[0004] Therefore, there is a need to provide an auxiliary structure for visual recognition equipment that can accurately and quickly transfer the product under test to the visual recognition station. Utility Model Content

[0005] The main objective of this invention is to provide an auxiliary structure for visual recognition devices, addressing the shortcomings of existing technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An auxiliary structure for a visual recognition device includes a device body and an operating table disposed on its upper surface. Side plates are provided on both sides of the front end of the operating table, and a plurality of carriers for loading products are placed between the two side plates. A take-out mechanism for removing the carriers is installed around the periphery of the two side plates. A transfer mechanism for gripping the carriers from the take-out mechanism is installed at the rear end of the operating table. The transfer mechanism transfers the carriers to the visual recognition station on the device body. The transfer mechanism is disposed opposite to the take-out mechanism.

[0008] Preferably, a conveyor belt is provided on the inner side of both side plates, and the two ends of each carrier are placed on the surface of the conveyor belt on the corresponding side to enable the carrier to slide along the conveyor belt.

[0009] Preferably, the removal mechanism includes vertical plates symmetrically installed on the outer sides of the two side plates. A propulsion cylinder is fixedly installed on the inner side of each vertical plate. The end of the propulsion cylinder is connected to an L-shaped fixing block. A horizontal plate is connected between the top ends of the two vertical plates. A first lifting cylinder is installed on the side of the horizontal plate near the rear end of the operating table. The first lifting cylinder is connected to a slider that can move up and down along it. The slider is connected to a first cylinder group consisting of several finger cylinders arranged side by side, which can follow it up and down along the first lifting cylinder, through a connecting plate. The gripper at the bottom of the finger cylinder removes the carrier and places it on the L-shaped fixing blocks on both sides.

[0010] Preferably, a guide plate is fixedly installed on the side of the first cylinder group facing the first lifting cylinder, and a lateral movement component that can drive the first cylinder group to move left and right is installed on the connecting plate.

[0011] Preferably, the lateral movement assembly includes a fixing member located above the connecting plate and fixedly connected to the guide plate. The fixing member is hollow. The lateral movement assembly also includes a stepper motor fixed to the connecting plate. The output end of the stepper motor is connected to a lead screw. The end of the lead screw is connected to the fixing member. When the stepper motor is started, it drives the lead screw to drive the fixing member to move left and right, thereby driving the first cylinder group connected to the fixing member to move left and right.

[0012] Preferably, a position sensor is mounted on the slider, and the position sensor is located above the fixing member.

[0013] Preferably, the transfer mechanism includes a drive cylinder fixedly installed at the rear end of the operating table, a second lifting cylinder fixedly connected to the upper end of the drive cylinder and slidable along it, the second lifting cylinder being fixedly connected to a convex plate, baffles facing the extraction mechanism being installed on both sides of the convex plate, and a pad for placing the side of the carrier being installed on the outer bottom of each baffle.

[0014] Compared with the prior art, the present invention will have at least the following beneficial effects:

[0015] ①The auxiliary structure of this utility model can quickly and accurately transfer the carrier loaded with NTC thermistors to the vision recognition station on the equipment body, and the vision recognition station performs visual recognition and detection on the solder joints of the NTC thermistors.

[0016] ② After the grippers of the first cylinder group pick up the NTC thermistor on the carrier, they place it on the L-shaped fixing block under the action of the first lifting cylinder.

Detailed Implementation

[0029] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely exemplary embodiments of this utility model, and not the only embodiments.

[0030] like Figures 1 to 7 As shown, an auxiliary structure for a visual recognition device includes a device body 1 and an operating table 2 disposed on its upper surface. Side plates 3 are disposed on both sides of the front end of the operating table 2. A plurality of product-loading carriers 4 are placed between the two side plates 3, each carrier 4 containing a plurality of products arranged side-by-side. Removal mechanisms for taking out the carriers 4 are installed on the outer sides of the two side plates 3. A transfer mechanism for gripping the carriers 4 from the removal mechanisms is installed at the rear end of the operating table 2. The transfer mechanism transfers the carriers 4 to a visual recognition station 28 on the device body 1. The transfer mechanism is disposed opposite to the removal mechanism. The auxiliary structure can transfer the product-loading carriers 4 to the visual recognition station 28 on the device body 1, where the visual recognition station 28 detects the products on the carriers 4. In this embodiment, the product loaded in the carriers 4 is an NTC thermistor.

[0031] like Figure 2 As shown, in actual operation, several carriers 4 loaded with NTC thermistors are first stacked between two side plates 3 by manual labor. The retrieval mechanism will then take out the carriers 4 loaded with NTC thermistors one by one. To facilitate the retrieval mechanism to quickly remove the carriers 4 in the rear row, a conveyor belt 5 is provided on the inner side of both side plates 3. The carriers 4 are placed directly on the conveyor belt 5. Specifically, the two ends of several carriers 4 are placed on the conveyor belt surface on the corresponding side so that the carriers 4 can slide along the conveyor belt 5. This allows the carriers 4 to move quickly, making it easy for the retrieval mechanism to quickly remove the carriers 4. It also ensures that the carriers 4 slide smoothly on the conveyor belt 5. Furthermore, it can save manpower and improve the moving efficiency of the carriers 4.

[0032] like Figures 2 to 5As shown, the removal mechanism that takes out the NTC thermistor from the conveyor belt 5 between the two side plates 3 includes vertical plates 6 symmetrically installed on the outer sides of the two side plates 3. A push cylinder 7 is fixedly installed on the inner side of each vertical plate 6. The end of the push cylinder 7 is connected to an L-shaped fixing block 8. The push cylinder 7 can drive the L-shaped fixing block 8 to move in the direction of the transfer mechanism. A horizontal plate 9 is connected between the tops of the two vertical plates 6. A first lifting cylinder 10 is installed on the side of the horizontal plate 9 near the rear end of the operating table 2. The first lifting cylinder 10 is connected to a slider 11 that can move up and down along it. The slider 11 is connected to a first cylinder group consisting of several finger cylinders 12 arranged side by side, which can follow it up and down along the first lifting cylinder 10, through a connecting plate 15. The gripper 13 at the bottom of the finger cylinder 12 takes out the carrier 4 and places it on the L-shaped fixing blocks 8 on both sides.

[0033] Specifically, after the carrier 4 carrying the NTC thermistor is placed on the conveyor belt 5, it is taken out by the removal mechanism. The specific operation process is as follows: the first lifting cylinder 10 descends to a position above the gripper 13 of several finger cylinders 12 connected to the first lifting cylinder 10, which can grip the NTC thermistor. After the finger cylinders 12 are activated, the gripper 13 grips the corresponding NTC thermistor to grip the entire carrier 4. The first lifting cylinder 10 rises so that the two sides of the carrier 4 can be placed in the position of the corresponding L-shaped fixing block 8. The push cylinders 7 inside the two vertical plates 6 drive the L-shaped fixing block 8 to move towards the gripped carrier 4 and move it below the carrier 4. The first lifting cylinder 10 descends so that the two sides of the carrier 4 can fall on the L-shaped fixing block 8. The two push cylinders 7 drive the L-shaped fixing block 8 carrying the carrier 4 to move towards the transfer mechanism, and the transfer mechanism transfers the carrier 4 to the vision recognition station 28 set on the equipment body 1 for subsequent operations.

[0034] It should be noted that since several NTC thermistors are mounted side by side in the carrier 4, and the NTC thermistors have a certain length, the clamps 13 in the first cylinder group of the removal mechanism can directly clamp the corresponding NTC thermistors, which can reduce the interference of the NTC thermistors on the L-shaped fixing block 8.

[0035] like Figure 6 and Figure 7As shown, in actual operation, after the removal mechanism removes the carrier 4, it needs to be moved. This is because the first cylinder group occupies a certain space, which will affect the transfer of the carrier 4 from the L-shaped fixing block 8 to the transfer mechanism. Therefore, in this embodiment, the following configuration is made: a guide plate 14 is fixedly installed on the side of the first cylinder group facing the first lifting cylinder 10. A lateral moving component that can drive the first cylinder group to move left and right is installed on the connecting plate 15. The guide plate 14 provides directional guidance for the movement of the lateral moving component. The function of the lateral moving component is to move the first cylinder group to a position that does not affect the transfer of the carrier 4. Under normal circumstances, the lateral moving component moves left and right. Specifically, the lateral moving component includes a fixing member 16 located above the connecting plate 15 and fixedly connected to the guide plate 14. The fixing member 16 is hollow. The lateral moving component also includes a fixing member. A stepper motor 17 is mounted on the connecting plate 15. The output end of the stepper motor 17 is connected to a lead screw 18. The end of the lead screw 18 is connected to a fixing member 16. When the stepper motor 17 is started, it drives the lead screw 18 to rotate and move the fixing member 16 left and right. This also drives the first cylinder group connected to the fixing member 16 to move left and right. More specifically, after the carrier 4 is placed on the L-shaped fixing block 8, the stepper motor 17 is started and the lead screw 18 is driven to rotate. The lead screw 18 drives the fixing member 16 to move in one of the left or right directions without affecting the movement of the L-shaped fixing block 8 to the transfer mechanism. After the L-shaped fixing block 8 is transferred to the transfer mechanism, the stepper motor 17 drives the lead screw 18 to return the fixing member 16 to its original position, and then drives the first cylinder group to return to its original position, continuing the removal operation for the next carrier 4 loaded with an NTC thermistor.

[0036] After the fixing member 16 is driven to another position, it needs to be returned to its original position. In order to accurately control the position of the fixing member 16 when it returns to its original position, a position sensor 19 is installed on the slider 11. The position sensor 19 is located above the fixing member 16. The setting of the position sensor 19 not only accurately controls the position of the fixing member 16 when it returns to its original position, but also accurately controls the position of the guide plate 14 fixedly connected to the fixing member 16 and the first cylinder group fixedly connected to the guide plate 14 when they return to their original positions.

[0037] After the carrier 4, equipped with an NTC thermistor, is removed from the retrieval mechanism, it needs to be transferred to the vision recognition station 28. This process is completed by a transfer mechanism, which includes a drive cylinder 20 fixedly installed at the rear end of the operating table 2. A second lifting cylinder 21, which can slide along the drive cylinder 20, is fixedly connected to the upper end of the drive cylinder 20. The second lifting cylinder 21 is fixedly connected to a convex plate 22. Both sides of the convex plate 22 are equipped with baffles 23 facing the retrieval mechanism. A pad 24 for placing the side of the carrier 4 is installed on the outer bottom of each baffle 23. The L-shaped fixing block 8 moves towards the transfer mechanism under the drive of the push cylinder 7. At the same time, the drive cylinder 20 starts and drives the second lifting cylinder 21 to move towards the retrieval mechanism. When the second lifting cylinder 21 moves to a position where the carrier 4 can be received, the carrier 4 on the L-shaped fixing block 8 enters the pad 24 on the convex plate 22, that is, the carrier 4 is transferred to the receiving mechanism. The two sides of the carrier 4 fall onto the corresponding pads 24, thereby enabling the carrier 4 to enter the transfer mechanism from the take-out mechanism. The transfer mechanism also includes a transverse guide rail 25 set on the equipment body 1. The bottom end of the transverse guide rail 25 is slidably connected to a second cylinder group. The second cylinder group includes at least two gripper cylinders 26 arranged side by side. The gripper 27 at the bottom of each gripper cylinder 26 grabs the carrier 4 body and transfers the carrier 4 from the pads 24 to the vision recognition station 28 set on the equipment body 1. Specifically, after the carrier 4 is transferred to the pads 24, the second lifting cylinder 21 rises and rises to the position where the gripper 27 of the gripper cylinder 26 can grab the carrier 4. Each gripper 27 grabs the carrier 4 body at the corresponding position. Then, the second cylinder group slides the carrier 4 loaded with NTC thermistors along the transverse guide rail 25 to the vision recognition station 28 for corresponding operations.

[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
