Specifically, the slider driving part 212 may be a linear driving cylinder, and the slider 211 is mounted at an output end of the linear driving cylinder. When no steel ball 620 is in the temporary storage channel 2111, the slide block driving component 212 drives the slide block 211 to make the temporary storage channel 2111 aligned with the first hole 2131, the steel ball 620 enters the temporary storage channel 2111, and the steel ball 620 in the feeding pipe 400 flows into the temporary storage channel 2111; when the temporary storage passage 2111 is filled with a predetermined number of steel balls, the slider driving part 212 drives the slider 211 to move so that the temporary storage passage 2111 is aligned with the second hole 2134, and the steel balls 620 are discharged from the temporary storage passage 2111 into the collecting passage 2211.

As shown in fig. 8, the thickness of the three sliders 211 is different, so that the length of the temporary storage passage 2111 of each slider 211 is different, and the diameter of the temporary storage passage 2111 is the same as that of the steel ball 620. The thickness of each slide block 211 is determined according to the sum of the heights of the preset number of steel balls 620, so that different temporary storage channels 2111 temporarily store different numbers of steel balls 620.

Fig. 8 also shows that the summary channel block 221 includes one summary channel 2211 and three summary branch channels 2212. The upper end of each collecting branch passage 2212 is respectively communicated with the corresponding second hole 2134, and the lower end is collected in one collecting passage 2211, so that the steel balls 620 flowing in from different temporary storage passages 2111 are collected in one collecting passage 2211 to be output, and different numbers of steel balls 620 can be output to the same assembly component 300. In other embodiments, the number of the summarizing branch channels 2112 may be other values, as long as it is ensured that the upper end of the summarizing branch channel 2212 has the corresponding second hole 2134, and the lower end is summarized in the same summarizing channel 2211.

For convenience of explaining the operation of the feed assembly 100 and the distribution assembly 200, the operation principle of the feed assembly 100 and the distribution assembly 200 is as follows: the steel balls 620 discharged from the feeding assembly 100 enter the six feeding pipes 400, the steel balls 620 enter each first hole 2131 through the feeding pipes 400, and then the steel balls 620 enter the corresponding temporary storage passage 2111 until the temporary storage passage 2111 is filled. Then, the slider driving component 212 corresponding to the required number of steel balls 620 drives the corresponding slider 211 to move along the x-axis direction, so that the temporary storage channel 2111 on the slider 211 is aligned with the corresponding second hole 2134, and the preset number of steel balls 620 fall into the summarizing channel 2211 in the summarizing module 220. In order to ensure that only a fixed number of steel balls 620 enter the summarizing passage 2211 each time, the driving devices 212 corresponding to the other two sliding blocks 211 do not work.

In addition, to achieve a faster flow of the steel balls 620 in the buffer channel 2111 into the summation channel 2211, the dispensing module 210 also comprises a blowing mechanism. Wherein, the blowing mechanism comprises an air pump and a blowing pipe. The gas-blowing pipe of the gas-blowing mechanism is mounted on the housing 213 of the dispensing module 210, and the gas-blowing mechanism can blow high-pressure gas into the temporary storage passage 2111. Specifically, as shown in fig. 5 and 7, for each group of the feeding pipe groups, three third holes 2132 are opened in the upper cover of the housing 213, each third hole 2132 is communicated with an air blowing pipe of an air blowing mechanism, and each third hole 2132 and a second hole 2134 corresponding to the third hole are arranged in a collinear manner along the thickness direction of the slider 211. When one end of the temporary storage channel 2111 on one sliding block 211 is communicated with the corresponding third hole 2132 and the other end of the temporary storage channel 2111 is communicated with the corresponding second hole 2134 of the temporary storage channel 2111, the blowing mechanism blows high-pressure gas into the temporary storage channel 2111, so that the steel balls 620 in the temporary storage channel 2111 are completely discharged into the collecting channel 2211.

In order to make the steel ball 620 enter the assembly 300 more quickly to complete the installation, each slide block 211 is provided with an air flow channel 2112. Air flow passage 2112 penetrates slider 211 from the thickness direction. The temporary storage channel 2111 and the air flow channel 2112 of each slider 211 are arranged in the x direction (first direction), and the distance between the projections of the air flow channel 2112 and the temporary storage channel 2111 on the horizontal plane is equal to the distance between the projections of the first hole 2131 and the second hole 2134 on the horizontal plane. When the temporary storage channel 2111 is aligned with the first hole 2131, the lower part of the air flow channel 2112 is aligned with the second hole 2134, the upper part of the air flow channel is aligned with the third hole 2132, the three form a channel, the air flow discharged by the air blowing mechanism blows the steel ball 620 into the gathering channel 2211 along the channel formed by the three, and the steel ball enters the assembly component 300 through the gathering channel 2211 to complete assembly; at this time, the temporary storage passage 2111 is opposite to the first hole 2131, the temporary storage passage 2111 can continue to collect the steel balls 620 from the feeding pipe 400, and when the temporary storage passage 2111 is filled with the steel balls 620, the next steel ball 620 output process can be performed, so that the assembly efficiency is improved.

Alternatively, to enhance the air flow effect, the air flow channels 2112 of the other two non-operating sliders 211 may communicate with the second hole 2134 and the third hole 2132, respectively, when one slider 211 is operating. At this point, high pressure air flows through air flow passage 2112 into summing passage 2211, enhancing the air flow in summing passage 2211, causing steel ball 620 to enter assembly 300 more quickly to complete the installation.

As shown in fig. 8, the summing module 220 includes a summing channel block 221, the summing channel block 221 includes three summing branch channels 2212, the upper ends of the three summing branch channels 2212 are respectively connected to three second holes 2134 corresponding to the three sliders 211, and the lower ends of the three summing branch channels 2212 are merged into the summing channel 2211. The steel balls 620 with the preset number enter the collecting branch passage 2212 from the corresponding second holes 2134 and then flow into the collecting passage 2211, so that the pressure valve core 600 with different numbers of steel balls 620 can be assembled on one device.

As shown in fig. 9, the mounting assembly 300 includes a mounting frame 310, a mounting lift module 320, a mounting nozzle module 330, and a workpiece placement module 340. Wherein, the fixed end of the assembly lifting module 320 is fixed on the assembly frame 310. The assembling lifting module 320 may drive the assembling nozzle module 330 mounted on the assembling lifting module 320 to move up and down linearly. The workpiece placing module 340 is used for storing the pressure valve core 600 to be assembled with the steel ball 620 and is located right below the nozzle assembling module 330, and the workpiece placing module 340 can also drive the pressure valve core 600 to rotate by taking the central axis of the pressure valve core 600 as an axis. In order to more clearly show the working principle of the main components of the assembly 300, the workpiece placing module 340 is hidden in fig. 9 except for the workpiece placing seat.

Specifically, the assembly lifting module 320 includes an assembly lifting driving member 321 and a nozzle mounting plate 322. Wherein the fitting cylinder 321 may be a linear driving cylinder. The body of the assembly cylinder 321 is fixed on the assembly frame 310, and the output end of the assembly cylinder 321 is fixedly connected with the nozzle mounting plate 322. The assembling cylinder 321 can drive the nozzle mounting plate 322 to reciprocate along the vertical direction. The nozzle-assembling module 330 is fixed to the nozzle-mounting plate 322. When the valve core 600 of the pressure valve to be assembled with the steel ball 620 is placed on the workpiece placing module 340, the linear driving cylinder drives the material nozzle mounting plate 322 to drive the material nozzle assembling module 330 to move downwards until the valve core 600 of the pressure valve enters the material nozzle assembling module 330 to install the steel ball 620. When the pressure valve spool 600 in the assembly nozzle module 330 is installed, the assembly cylinder 321 drives the assembly nozzle module 330 to move upwards, and the assembly nozzle module 330 is separated from the pressure valve spool 600, so that the pressure valve spool 600 is convenient to take out.

In order to prevent the assembly lifting module 320 from deviating from moving in the vertical direction, as shown in fig. 9, the assembly 300 further includes a lifting guide column 323, the lifting guide column 323 is fixedly connected to the frame 310, and the lower end of the lifting guide column 323 is connected to the nozzle mounting plate 322. The lifting guide post 323 is arranged in the vertical direction, and the material nozzle mounting plate 322 can slide relatively along the vertical direction relative to the lifting guide post 323, so that the stability of the lifting motion of the material nozzle mounting plate 322 is ensured.

Fig. 10 is a sectional view of an assembly nozzle module 330, and the assembly nozzle module 330 includes a nozzle 331, a nozzle gate 332, and a nozzle gate driving part 333. The nozzle gate 332 is installed in the nozzle 331, and the nozzle gate driving part 333 is connected to the nozzle gate 332.

Specifically, the center of the nozzle 331 is provided with a workpiece mounting hole 3312 for the valve core 600 of the pressure valve to enter, the sidewall is provided with a feeding channel 3311 for the steel ball 620 to enter, and the upper end of the feeding channel 3311 is communicated with the feeding pipe 500. The steel ball 620 to be installed flows in from the feeding pipe 500, and the high pressure gas blown by the blowing mechanism pushes the steel ball 620 into the feeding channel 3311 and finally into the pressure valve core 600. The nozzle gate 332 is installed in the workpiece installation hole 3312 and connected to a nozzle gate driving member 333. The nozzle gate driving part 333 may be a linear driving cylinder, and the nozzle gate 332 is connected to an output end of the linear driving cylinder. The nozzle gate driving part 333 may drive the nozzle gate 332 to reciprocate up and down. When the pressure valve spool 600 is not present in the workpiece mounting hole 3312, the nozzle gate 332 is located at the bottom dead center, and the discharge port of the feed passage 3311 is blocked by the sidewall of the nozzle gate 332, so that the steel ball 620 cannot be discharged. When the valve core 600 of the pressure valve to be assembled with the steel ball 620 is in place in the workpiece mounting hole 3312, the nozzle gate 332 moves upwards, the discharge hole of the feed channel 3311 is opened, and the steel ball 620 can smoothly enter the valve core 600 of the pressure valve to complete the assembly. When the valve core 600 of the pressure valve completes the assembly of the steel ball 620, the nozzle gate 332 moves downwards again to block the discharge hole of the feeding channel 3311, and the steel ball 620 is prevented from being discharged. The up-and-down movement of the nozzle gate 332 opens or blocks the discharge hole of the feed channel 3311, so as to control the transmission of the steel ball 620 between the feed pipe 3311 and the pressure valve core 600, thereby ensuring the controllability of the installation process.

For convenience of explaining the operation of the assembly 300, the assembly 300 operates according to the following principle: an operator fixes and places the pressure valve spool 600 to be assembled with the steel ball 620 on the workpiece placement module 340, and the assembly lifting driving component 321 drives the nozzle mounting plate 322 to drive the nozzle 331 to move downwards along the vertical direction until the pressure valve spool 600 enters the workpiece mounting hole 3312 on the nozzle 331. At this time, the nozzle gate driving part 333 drives the nozzle gate 332 to move upward, the discharge port of the feeding channel 3311 is opened, the high-pressure gas from the blowing mechanism blows the steel ball 620 into the feeding channel 3311 through the feeding pipe 500, then the high-pressure gas continuously blows the steel ball 620 into the steel ball mounting hole 21 on the pressure valve spool 600, the pressure valve spool 600 placing part 340 drives the pressure valve spool 600 to rotate, and the assembly of the steel balls 620 in all the steel ball mounting holes 211 on the pressure valve spool 600 is completed. After the pressure valve spool 600 is installed, the nozzle gate driving part 333 drives the nozzle gate 332 to move downward, and blocks the discharge port of the feed passage 3311. Then, the lifting driving component 321 is assembled to drive the nozzle mounting plate 322 to drive the nozzle 331 to move upwards in the vertical direction, and the pressure valve core 600 is separated from the workpiece mounting hole 3312, so that a primary assembly process is completed.

For convenience of understanding, the working principle of the assembling device provided by the embodiment is as follows:

the steel balls 620 are initially stored in the feed tank 101 and the feed agitator drive unit 102 drives the feed agitator 103 with the hoop 1031 mounted thereon to reciprocate linearly within the feed tank 101 to agitate the steel balls 620. The steel balls 620 at the bottom of the feed tank 101 are stirred by the feed stirrer 103 into the six feed pipes 400, respectively. The steel balls 620 in the six feeding pipes 400 respectively enter the corresponding temporary storage channels 2111 through the corresponding first holes 2131. Then the corresponding required number of the sliders 211 are driven by the corresponding slider driving components 212, so that the temporary storage channels 2111 are communicated with the corresponding collecting branch channels 2212, the steel ball 620 falls into the collecting branch channels 2212 from the temporary storage channels 2111 through the second hole 2134, and then the steel ball 620 enters the collecting branch channels 2212 and further enters the feeding pipe 500. When the steel ball 620 is completely discharged from the temporary storage channel 2111, the slide block 211 is reset, so that the temporary storage channel 2111 is communicated with the feeding pipe 400 again to enable the temporary storage channel 2111 to continuously collect the steel ball 620, at this time, high-pressure air entering from the third hole 2132 connected with the blowing pipe of the blowing mechanism enters the summarizing channel 2211 through the air flow channel 2112, the steel ball 620 is pushed into the feeding channel 3311 on the assembling nozzle 331 through the feeding pipe 500, and the air flow continuously pushes the steel ball 620 to enter the pressure valve core 600 through the discharging port of the feeding channel 3311, so that one assembling process is completed.

Before the steel ball 620 to be mounted leaves the distributing component 200, the mounting lifting driving component 321 drives the nozzle mounting plate 322 to move downwards along the axial direction of the lifting guide column 323 until the pressure valve core 600 of the steel ball 620 to be mounted placed on the workpiece placing module 340 enters the workpiece mounting hole 3312 of the nozzle 331, and at this time, the nozzle gate driving component 333 drives the nozzle gate 332 to move upwards to open the discharge hole of the feeding channel 3311, so that the preparation work before mounting is completed. After completion of one assembly process, the nozzle gate driving part 333 drives the nozzle gate 332 downward until blocking the lower outlet of the feed passage 3311. The assembly lifting driving part 321 drives the nozzle mounting plate 322 to move upwards along the axial direction of the lifting guide column 323, so that the assembled pressure valve core 600 can be conveniently taken out of the workpiece placing module 340 and a new pressure valve core 600 of the steel ball 620 to be assembled can be conveniently placed on the workpiece placing module 340.

When all the work of the equipment is completed and the residual steel balls 620 in the feeding assembly 100 need to be cleaned, the material cleaning driving part 111 of the material cleaning module 110 is opened, so that the second material cleaning hole 1121 on the material cleaning driving part 111 is opposite to the first material cleaning hole 1011 on the bottom surface of the feeding box 101, and the steel balls 620 in the feeding assembly 100 are discharged from the first material cleaning hole 1011.
