Example one

As shown in fig. 1 to 7, an infrared radiation carbon ink electric heating plate detection device includes a conveying mechanism 100, wherein the conveying mechanism 100 is adapted to convey an electric heating plate 300; the screening mechanism 200 is suitable for screening and recycling the electric heating plates 300, the screening mechanism 200 comprises an upper screening plate 210, a lower screening plate 220, a guide part 230, a screening part 240, a glue scraping part 250 and a glue applying part 260, wherein the guide part 230, the screening part 240, the glue scraping part 250 and the glue applying part 260 are sequentially arranged on the lower screening plate 220, the glue applying part 260 is arranged between the upper screening plate 210 and the lower screening plate 220, the screening part 240 comprises two guide bars 241 obliquely arranged between the upper screening plate 210 and the lower screening plate 220 and two limit plates 242 respectively arranged on one side of the two guide bars 241, the two guide bars 241 are respectively arranged on two sides of the lower screening plate 220, a sliding space 243 is arranged between the limit plates 242 and the lower screening plate 220, and the size of the sliding space 243 is matched with the size of the main plate 310 of the electric heating plate 300; the conveying mechanism 100 conveys the electric heating plate 300 to the screening mechanism 200, and the guiding part 230 is suitable for adjusting the position of the electric heating plate 300; when the electric heating plate 300 has at most one tab 320, the electric heating plate 300 passes through the sliding space 243 to the scraping part 250, when the electric heating plate 300 has two tabs 320, the tabs 320 pass through the guide strips 241 to slide to the glue smearing part 260 on one side of the upper screening plate 210, the scraping part 250 is adapted to peel off the chip 330 on the electric heating plate 300 from the electric heating plate 300 and melt the glue on the chip 330, and the glue smearing part 260 coats the glue melted on the chip 330 on the qualified electric heating plate 300. Because the tab 320 on the two sides of the electric heating plate 300 is soft, when the qualified electric heating plate 300 passes through the guide bar 241, the main plate 310 in the middle of the electric heating plate 300 may sink, and the unqualified electric heating plate 300 located in the sliding space 243 can play a supporting role, so as to prevent the tab 320 of the qualified electric heating plate 300 from being broken.

In order to ensure that the main plate 310 of the electric heating plate 300 is positioned between the lower screening plates 220 for conveying, the guiding portion 230 includes two oppositely disposed guiding plates 231, the guiding plates 231 are fixed on the upper screening plates 210, wherein the guiding plates 231 are in the shape of circular arc, and the minimum distance between the two guiding plates 231 is matched with the size of the main plate 310 of the electric heating plate 300. The guide plate 231 allows the electric heating plate 300 to be transported at the middle position of the lower screening plate 220, which may affect the screening effect if the electric heating plate 300 is deflected to one side. The guide plate 231 is arranged on the upper-layer screening plate 210, the movement of the main plate 310 is limited, the tabs 320 are arranged on two sides of the main plate 310 and are located in the middle of the main plate 310, the guide plate 231 cannot contact the tabs 320, and therefore the guide plate 231 only limits the movement track of the main plate 310. The guide plates 231 are arc-shaped, and the end with the largest distance between the two guide plates 231 is arranged close to the end of the conveying mechanism 100 which conveys the electric heating plate 300, so that the guide effect is achieved, and the electric heating plate 300 which enters gradually draws close to the middle. The guide plate 231 plays a role in first positioning, and ensures the position of the electric heating plate 300 when being conveyed in each time.

The limiting plate 242 is arranged in a circular arc on one side away from the guide bar 241. The spacing plate 242 is spaced from the lower screening plate 220 by a certain distance, that is, the spacing plate 242 is spaced from one end of the guide bar 241 close to the lower screening plate 220 by a certain distance. When the electric heating plate 300 has one tab 320, one end of the electric heating plate 300 having the tab 320 slides on the guiding strip 241, and the other end slides in the sliding space 243, and when one end of the electric heating plate 300 not having the tab 320 moves a distance in the sliding space 243, the electric heating plate 300 having one end of the tab 320 moves a small distance upwards first, due to the limitation of the sliding space 243, the end of the electric heating plate 300 having the tab 320 moves downwards, and under the action of the arc, due to the spacing plate 242 and the guiding strip 241 being close to one end of the lower screening plate 220, the end can be clamped in the sliding space 243, and due to the flexible material of the tab 320, the tab 320 is bent, and then the electric heating plate 300 is conveyed from the sliding space 243.

The scraping portion 250 includes a baffle 251 fixed on the upper screening plate 210, the baffle 251 is disposed toward the lower screening plate 220, a heating device is disposed in the baffle 251, wherein when the chip 330 on the electric heating plate 300 abuts against the baffle 251, the heating device heats the chip 330 to melt the glue on the chip 330, and the chip 330 is peeled off from the electric heating plate 300. The chip 330 is disposed above the front end of the electric heating plate 300 and in the middle of the electric heating plate 300, when the chip 330 contacts the baffle 251, the hot melt adhesive melts due to the heat of the chip 330, the chip 330 abuts against the baffle 251, and the conveying mechanism 100 conveys the electric heating plate 300, thereby peeling the chip 330 off the electric heating plate 300.

The lower screening plate 220 is further provided with a mounting groove 211, the position of the mounting groove 211 corresponds to the position of the baffle 251, wherein when the chip 330 is peeled off from the electric heating plate 300, the chip 330 can fall into the mounting groove 211. The peeled chip 330 can be dropped and collected from the mounting groove 211, and the chip 330 cannot move to the rear of the baffle 251, i.e., in the direction of the squeegee 250, by the action of the baffle 251.

Two fixing plates 270 oppositely arranged on the lower-layer screening plate 220 are further arranged between the screening part 240 and the glue scraping part 250, wherein the fixing plates 270 are also arc-shaped, and the minimum distance between the two fixing plates 270 is matched with the size of the main plate 310 of the electric heating plate 300. The fixing plate 270 and the guide plate 231 act in the same direction, and the moving track of the electric heating plate 300 is adjusted, so that the main plate 310 of the electric heating plate 300 can move in the middle of the lower screening plate 220, and finally the position of the chip 330 is conveniently matched with the position of the glue coating groove 262. The end of the two fixing plates 270 having the larger distance therebetween is disposed near the screening part 240 so that the electric heating plate 300 contacts the arc-shaped fixing plates 270 and then gradually approaches toward the center. The fixing plate 270 serves a second positioning function, and ensures a position of the electric heating plate 300 every time it is conveyed.

The glue smearing part 260 comprises an arc-shaped driving plate 261 arranged on the lower screening plate 220 and a glue coating groove 262 arranged on the upper screening plate 210, wherein the arc-shaped driving plate 261 is positioned on one side of the fixing plate 270 away from the guide part 230; when the electric hot plate 300 passes through the arc-shaped driving plate 261, the glue melted on the electric hot plate 300 can be applied to the qualified electric hot plate 300 from the glue coating groove 262. The unqualified electric hot plate 300 moves upwards under the action of the arc-shaped driving plate 261, and then the part of the unqualified electric hot plate 300 where the glue is melted is smeared on the qualified electric hot plate 300 from the glue coating groove 262, so that the qualified electric hot plate 300 can be labeled conveniently at the later stage. The thickness of the upper screening plate 210 is relatively thin, and the glue protrudes from the main plate 310 of the electric heating plate 300, so that when the electric heating plate 300 is tilted, the glue protruding from the main plate 310 of the electric heating plate 300 can be smeared on the bottom of the qualified electric heating plate 300. The arc-shaped driving plate 261 is further provided with a glue overflow groove, so that glue can fall into the glue overflow groove conveniently when dripping.

In order to prevent glue from being applied to the upper screening plate 210, the glue applying groove 262 has a length direction parallel to the conveying direction of the electric heating plate 300. The glue coating part is positioned in the glue coating groove 262, so that the glue cannot be adhered to two sides of the glue coating groove 262, namely the upper-layer screening plate 210, and the movement stability of the electric heating plate 300 on the upper-layer screening plate 210 is ensured. Since the electric heating plates 300 are one after another, the qualified electric heating plates 300 are contacted by one electric heating plate 300, and the new qualified electric heating plate 300 pushes the former qualified electric heating plate 300 to move for delivery.

The conveying mechanism 100 includes a first conveying belt 110, a second conveying belt 120, a third conveying belt 130, and a grabbing mechanism including a support and a gripper slidably disposed on the support, wherein,

the first conveyer belt 110 is adapted to convey the qualified electric heating plates 300, the second conveyer belt 120 is adapted to convey the unqualified electric heating plates 300, and the third conveyer belt 130 is adapted to convey the electric heating plates 300 to be screened to the screening mechanism 200; the gripper is adapted to grip the electric hot plate 300 after the glue is applied onto the first conveyor belt 110. The unqualified electric heating plates 300 are directly conveyed to the second conveying belt 120 from the lower screening plate 220, and the mechanical claw grabs the qualified electric heating plates 300 and conveys the qualified electric heating plates to the first conveying belt 110 for subsequent treatment. The third conveyor belt 130 conveys the electric heating plates 300 to be screened onto the screening mechanism 200 for screening.

In order to prevent the electric heating plates 300 from being stacked and not moving, guide grooves are formed on the first conveyor 110, the second conveyor 120 and the third conveyor 130, and guide blocks adapted to the guide grooves are also formed on the electric heating plates 300. The guide block is inserted into the guide groove, so that a third positioning effect is achieved, the electric heating plate 300 is prevented from shaking in the guide groove, the horizontal and transverse movement of the electric heating plate 300 is limited, and the electric heating plate 300 can still move upwards.

The working principle is as follows: the third conveyor belt 130 conveys the electric heating plates 300 to be screened to the screening mechanism 200, and the electric heating plates 300 to be screened are adjusted to enter the screening mechanism 200 under the action of the guide plates 231, so that each electric heating plate 300 main plate 310 can be positioned on the central line of the two guide strips 241 and enter the screening part 240.

When the electric heating plate 300 to be screened has two tabs 320, the electric heating plate 300 moves to the upper screening plate 210 under the action of the guiding bars 241, that is, the electric heating plate 300 is a qualified electric heating plate 300, and the electric heating plate 300 moves by pushing the electric heating plate 300 by the qualified electric heating plate 300.

When the electric heating plate 300 to be screened has a tab 320, because the position of the electric heating plate 300 has been adjusted to the middle position of two guide bars 241 under the action of the guide plate 231, one end of the electric heating plate 300 having the tab 320 slides on the guide bar 241, and the other end slides in the sliding space 243, after one end of the electric heating plate 300 not having the tab 320 moves a distance in the sliding space 243, the electric heating plate 300 at the end having the tab 320 of the electric heating plate 300 moves a short distance upwards, because of the limitation of the sliding space 243, the end of the electric heating plate 300 having the tab 320 moves downwards, and is clamped into the sliding space 243 under the action of the arc, and then is conveyed from the lower screening plate 220, and the electric heating plate 300 is a rejected electric heating plate 300.

When the electric heating plate 300 to be screened does not have the tab 320, since the position of the electric heating plate 300 is already adjusted to the middle position of the two guide bars 241 by the guide plate 231, both sides of the electric heating plate 300 directly move from the sliding space 243 to the glue scraping part 250, and the electric heating plate 300 is a defective electric heating plate 300.

The qualified electric heating plates 300 move on the upper screening plate 210, and the unqualified electric heating plates 300 move to the fixing plate 270, adjust the positions of the unqualified electric heating plates 300 again, and then move to the glue scraping part 250. The chip 330 is disposed above the front end of the electric heating plate 300 and in the middle of the electric heating plate 300, when the chip 330 contacts the baffle 251, the hot melt adhesive melts due to the heat of the heating device of the chip 330, the chip 330 abuts against the baffle 251, and the third conveyor belt 130 is always conveying the electric heating plate 300, thereby peeling the chip 330 off the electric heating plate 300. The hot melt adhesive is then left on the electric heating plate 300 and protrudes above the main plate 310 of the electric heating plate 300. The third conveyer belt 130 moves the electric hot plate 300 with the chip 330 removed to the glue smearing part 260, the unqualified electric hot plate 300 moves upwards under the action of the arc-shaped driving plate 261, and then the part of the glue at the head of the unqualified electric hot plate 300, which is melted, is smeared on the qualified electric hot plate 300 from the glue smearing groove 262, so that the qualified electric hot plate 300 can be labeled conveniently at the later stage.

Finally, the unqualified electric heating plate 300 is conveyed to the second conveying belt 120 under the action of the third conveying belt 130, and the mechanical claw conveys the electric heating plate 300 which is coated with the glue to the first conveying belt 110 for subsequent labeling treatment.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
