Technical Field

The present application relates to the field of battery manufacturing, and in particular, to a measurement apparatus and a measurement method used in the field of battery manufacturing.

Background

As the energy density of lithium batteries is required to be higher (volume energy density is equal to battery energy/battery volume) in terminal products such as electronic products and electric vehicles, the accuracy of measurement of battery dimensions (including length, width and height) is also required to be higher. At present, the main working principle of the equipment for measuring the size of the battery is as follows: and abutting the battery against the fixed plate, driving the movable pressing plate to move, pressing the battery by the movable pressing plate, and calculating the size of the battery by calculating the displacement of the movable pressing plate. The measurement mode has higher requirements on the installation angle of the movable pressure plate and the fixed plate. If the parallelism of the installation of the fixed plate and the movable pressing plate is poor, namely the deviation of the installation angle is large, the final size measurement result is influenced. Therefore, a measuring apparatus and a measuring method are required to measure the installation angle of the fixed plate and the movable platen.

In order to solve the problem that the installation angles of the fixed plate and the movable pressing plate in the battery size measuring equipment are difficult to measure, a measuring device and a measuring method are needed.

Fig. 1 is a schematic structural view of a battery thickness measuring apparatus 100. The battery thickness measuring apparatus 100 (hereinafter referred to as the apparatus 100) is used to measure the size of the battery 200. As shown in fig. 1, the apparatus 100 may include a stage 110, a fixed plate 120, a movable platen 130, a linear drive 150, and a displacement sensor 170.

Platform 110 is the mounting platform for apparatus 100. The platform 110 may include a mounting surface 111 thereon.

The fixing plate 120 may be fixedly mounted on the platform 110. The fixing plate 120 may include a first measured surface 121. The first measured surface 121 may be perpendicular to the mounting surface 111.

The movable platen 130 may be slidably mounted on the platform 110. The movable platen 130 may include a second measured surface 131. The second measured surface 131 may be disposed opposite to and parallel to the first measured surface 121. The movable platen 130 is movable relative to the fixed platen 120 in a direction perpendicular to the first surface 121 and the second surface 131 to be measured, so that the distance between the first surface 121 and the second surface 131 to be measured is changed.

The linear driving device 150 may be mounted on the stage 110 and may be connected to the movable platen 130 for driving the movable platen 130 to move relative to the fixed platen 120. The linear drive 150 may include a power unit 151. In some embodiments, the linear drive 150 may also include a connecting rod 153. The power unit 151 is used to provide linear motion to the linear driving unit 150. The power unit 151 may be directly connected to the movable platen 130, or may be connected to the movable platen 130 through a connection rod 153. The power device 151 may be a linear motor, an electric push rod, a linear module, or the like. Both ends of the connection rod 153 may be connected to the power unit 151 and the movable platen 130, respectively. The connecting rod 153 can move the movable platen 130 relative to the fixed platen 120 under the driving of the power device 151.

The displacement sensor 170 may be mounted on the platform 110. The probe 171 on the displacement sensor 170 may be in contact with the movable platen 130. A spring device (not shown in fig. 1) is provided between the probe 171 and the movable platen 130 so that the probe 171 is always in contact with the movable platen 130. When the linear driving device 150 drives the movable platen 130 to move, the probe 171 moves together with the movable platen 130 and may feed back the displacement of the movement of the movable platen 130 to the displacement sensor 170.

As shown in fig. 1, the apparatus 100 measures the thickness dimension of the battery 200 by first placing the battery 200 between the first measured surface 121 of the fixed plate 120 and the second plane 31 of the movable platen 130; the linear driving unit 150 drives the movable platen 130 to move toward the fixed platen 20 until the battery 200 is clamped between the fixed platen 120 and the movable platen 130; the thickness of the battery 200 is calculated by the displacement of the movable platen 130 detected by the displacement sensor 170.

It should be noted that the movable platen 130 and the fixed platen 120 may be disposed horizontally, and the movable platen 130 may move in the horizontal direction with respect to the fixed platen 120. The movable platen 130 and the fixed platen 120 may also be vertically disposed, and the movable platen 130 may move in a vertical direction with respect to the fixed platen 120. Of course, the movable platen 130 and the fixed platen 120 are oppositely disposed in other directions. The device 100 can be used for measuring the length, width and height of the battery 200, and can also be used for measuring the size of other square products, and the measuring method is the same as that of the battery 200, and the description thereof is omitted.

The relative mounting angles of the fixed plate 120 and the movable platen 130 are important to the apparatus 100. For example, in the apparatus 100, the fixed plate and the movable platen 130 should be nominally disposed in parallel. If the first measured surface 121 of the fixed plate 120 and the second measured surface 131 of the movable platen 130 are installed in a poor parallelism, i.e., the installation angle deviation is large, the final dimension measurement result will be influenced. Therefore, it is important to measure the mounting angles of the first measured surface 121 and the second measured surface 131 during the mounting of the apparatus 100. Accordingly, in other devices there is often a requirement to maintain a certain preset angle between certain two planes. When the angle between the two planes deviates greatly from the preset angle, the operation accuracy of the other devices is affected. Therefore, it is important to measure the angle between the two measured surfaces accurately.

The present application provides a measuring device, such as the measuring device 300 shown in fig. 2-3, which can be used to measure the installation angle between the first measured surface 121 of the fixed plate 120 and the second measured surface 131 of the movable platen 130 of the apparatus 100, thereby ensuring that the installation of the fixed plate 20 and the movable platen 130 of the apparatus 100 meets the requirements and improving the measurement accuracy of the apparatus 100. It should be noted that the measuring apparatus 300 may be used to measure not only whether the first measured surface 121 and the second measured surface 131 of the device 100 are parallel, but also whether the angle between the first measured surface 121 and the second measured surface 131 of other devices is close enough to the preset installation angle. The first measured surface 121 is movable relative to the second measured surface 131.

Fig. 2 is a front view of a measuring device 300 according to an embodiment of the present application; fig. 3 is a right side view of a measurement device 300 according to an embodiment of the present application. As shown in fig. 2 and 3, the measuring device 300 may include a plurality of pressure sensors 310 and an elastic member 320. In some embodiments, the measurement device 300 may further include a reference block 350 and a signal acquisition device 360. In some embodiments, the measurement device 300 may further include a signal processing device 370.

Pressure sensor 310 may be used to measure the pressure to which it is subjected. The plurality of pressure sensors 310 may be mounted on the elastic member 320 and distributed at different positions on the elastic member 320 for measuring the pressure applied to different positions of the elastic member 320. When the measuring device 300 is in operation, the plurality of pressure sensors 310 may be installed between the elastic member 320 and the first surface 121 and pressed by the second surface 131, so as to measure the pressure applied to the elastic member 320. The number of pressure sensors 310 may be 1, 2, 3, etc.

The elastic member 320 is a compressible member having elasticity. The elastic member 320 can generate a certain deformation amount under the pressure, and the deformation amount is positively correlated with the pressure, i.e. the larger the pressure is, the larger the deformation amount is. Conversely, the greater the amount of deformation of the elastic member 320, the greater the pressure that is received. For example, the deformation of the elastic member 320 is proportional to the pressure. The elastic component can be a single elastic body or a plurality of elastic bodies. For example, the elastic member 320 may be composed of a plurality of elastic bodies 330. The resilient member 320 may include a first end 321 and a second end 322. For example, in the case where the elastic members 320 are formed by the plurality of elastic bodies 330, each elastic body 330 includes the first end 321 and the second end 322. A plurality of pressure sensors 310 may be mounted on a first end 321 of the resilient member 320. When the measuring device 300 measures the angle between the first measured surface 121 and the second measured surface 131, the measuring device 300 is placed between the first measured surface 121 and the second measured surface 131, so that the first end 321 abuts against the first measured surface 121, and the second end 322 abuts against the second measured surface 131, namely, the elastic member 320 is clamped by the first measured surface 121 and the second measured surface 131; the elastic member 320 is deformed by the first surface 121 and the second surface 131, and the plurality of pressure sensors 310 measure the pressure distribution between the first surface 121 and the second surface 131. When the first surface to be measured 121 and the second surface to be measured 131 are not absolutely parallel to each other, the elastic member 320 is deformed by different portions. Accordingly, the pressure sensors 310 at different locations are subject to different pressures; according to the pressure detected by the pressure sensor 310 at different positions on the elastic member 320, the deformation amount of different positions on the elastic member 320 can be calculated; based on the difference between the amounts of deformation at the different portions and the distribution coordinates of the pressure sensors 310, the angle between the first measured surface 121 and the second measured surface 131 is calculated.

As previously described, the resilient member 320 may be a large resilient compressible elastomer 330. The elastic member 320 may also include a plurality of small highly uniform elastic compressible elastic bodies 330, as shown in fig. 2 and 3, the number of the elastic bodies 330 being 4. Of course, the number of the elastic bodies may be any number, for example, the number of the elastic bodies 330 may be 1, 2, 3, etc., and the present application is not limited thereto. The elastic body 330 is made of an elastic material. The material of the elastic body 330 may be rubber, polyurethane, a spring, etc. The material of the plurality of elastic bodies 330 may be the same or different. For example, at least one elastic body 330 of the elastic bodies 330 is made of rubber. Each of the plurality of elastic bodies 330 may have at least one of the plurality of pressure sensors 310 mounted thereon. For example, the number of pressure sensors 310 that can be mounted on each elastic body 330 can be 1, 2, 3, and so on. As shown in fig. 3, a pressure sensor 310 may be mounted at the first end 321 of each elastomer 330. It should be noted that, in the initial state, the heights of the elastic bodies 330 need to be consistent to ensure the accuracy of the measurement of the first measured surface 121 and the second measured surface 131.

The measuring device 300 provided by the application can rapidly measure the compression amount of different parts by combining the elastic component 320 and the pressure sensor 310, has high measurement sensitivity, and can be used for measuring the angle between the first measured surface 121 and the second measured surface 131 and even measuring the parallelism between the first measured surface 121 and the second measured surface 131. And, by changing the distribution orientation of the pressure sensors 310, it is possible to measure the parallelism between the first measured surface 121 and the second measured surface 131 in different directions. In addition, by increasing the number of distributions of the pressure sensors 310, the accuracy of the measurement can be increased.

When the measuring apparatus 300 is in operation, the first end 321 of the elastic member 320 may directly abut against the first surface to be measured 121, or may indirectly abut against the first surface to be measured 121. Such as the elastic member 320 of the measuring device 300 shown in fig. 2 and 3, is indirectly abutted against the first measured surface 121. In fig. 2 and 3, the measurement apparatus 300 may further include a reference block 350. The reference block 350 is a mounting base of the measuring device 300. The elastic member 320 is mounted on the reference block 350. The reference block 350 may include a first face 351 and a second face 352. The first surface 351 is a reference surface of the measuring apparatus 300. The first face 351 may be disposed parallel to the second face 352. The first end 321 of the elastic member 320 may be connected with the second face 352 of the reference block 350. When the measuring device 300 measures the angle between the first measured surface 121 and the second measured surface 131, the first surface 351 of the reference block 350 abuts against the first measured surface 121, the first end 321 of the elastic member 320 abuts against the first measured surface 121 indirectly through the reference block 350, the plurality of pressure sensors 310 are distributed between the first end 321 of the elastic member 320 and the second surface 352 of the reference block 350, further, the second end 322 of each elastic member 330 and the second surface 352 of the reference block 350, the second end 322 of the elastic member 320 abuts against the second measured surface 131, and the first measured surface 121 and the second measured surface 131 clamp the elastic member 320; the elastic member 320 is deformed by the first surface 121 and the second surface 131, and the plurality of pressure sensors 310 measure the pressure distribution between the first surface 121 and the second surface 131. Since the first surface to be measured 121 and the second surface to be measured 131 are not absolutely parallel to each other, the deformation amount of different portions of the elastic member 320 is different, and the pressure applied to the pressure sensor 310 is also different; according to the pressure detected by the pressure sensor 310 at different positions on the elastic member 320, the deformation amount of different positions on the elastic member 320 can be calculated; based on the difference between the amounts of deformation at the different portions and the distribution coordinates of the pressure sensors 310, the angle between the first measured surface 121 and the second measured surface 131 is calculated. The arrangement of the elastic member 320 mounted on the reference block 350 makes the measuring device 300 more easily integrated and more convenient and reliable in measurement.

As shown in fig. 2 and 3, the measuring device 300 may further include a signal acquisition device 360. The signal acquisition device 360 may be electrically connected to the plurality of pressure sensors 310 and may be capable of acquiring data from the plurality of pressure sensors 310. The signal acquisition device 360 acquires the values of the plurality of pressure sensors 310 and displays the values on the display screen. The calculator can calculate the angles of the first measured surface 121 and the second measured surface 131 according to the data acquired by the signal acquisition device 360 and the position coordinates of the distribution of the plurality of pressure sensors 310. Of course, the data collected by the signal collecting device 360 may also be transmitted to the signal processing device 370, and the angle between the first measured surface 121 and the second measured surface 131 may also be calculated by the signal processing device 370.

In some embodiments, the measurement device 300 may further include a signal processing device 370. The signal processing device 370 may be communicatively connected to the signal acquisition device 360, and may be capable of calculating the angles of the first measured surface 121 and the second measured surface 131 based on the data of the plurality of pressure sensors 310 and the distribution of the positions of the plurality of pressure sensors 310 on the first end 321. The signal processing device 370 may receive the data collected by the signal collecting device 360, and calculate the angles of the first measured surface 121 and the second measured surface 131 according to the preset position distribution of the pressure sensors 310 on the first end 321, that is, the position coordinates distributed on the second surface 352 of the reference block 350. The signal processing device 370 may enable the angle to be calculated more quickly and accurately while saving time and labor costs.

In another aspect, the present application further provides a method for measuring by the measuring apparatus 300, which is used for measuring an angle between the first measured surface 121 and the second measured surface 131. Fig. 4 is a schematic diagram 400 illustrating a measuring apparatus 300 for measuring angles of a fixed plate 120 and a movable platen 130 according to an embodiment of the present disclosure. The method may include:

s410: the measuring device 300 is placed between the first measured surface 121 and the second measured surface 131, and the second measured surface 131 is driven to move towards the first measured surface 121, so that the first end 321 of the elastic member 320 of the measuring device 300 abuts against the first measured surface 121, and the second end 322 of the elastic member 320 abuts against the second measured surface 131.

Specifically, the measurement device 300 may include an elastic member 320 and a plurality of pressure sensors 310, the plurality of pressure sensors 310 being mounted at a first end 321 of the elastic member 320. As shown in fig. 4, the measuring device 300 includes an elastic member 320, a pressure sensor 310a, and a pressure sensor 310 b. The elastic member 320 includes an elastic body 330a and an elastic body 330 b. The pressure sensors 310a and 310b are installed at one ends of the elastic bodies 330a and 330b, respectively, connected to the second surface 352 of the reference block 350. The distance between pressure sensor 310a and pressure sensor 310b is X. As shown in fig. 4, the measuring device 300 is interposed between the fixed plate 120 and the movable platen 130. As described above, the movable platen 130 is movable relative to the fixed platen 120 in the direction perpendicular to the first surface 121 to be measured (the first surface 121 to be measured) by the linear driving unit 150.
