Description

Technical Field

[0001] This invention relates to the field of testing technology, and in particular to a quality testing device for film connectors after production. Background Technology

[0002] The post-production quality inspection device for film fasteners is a specialized device used to detect appearance defects and adhesive performance of film fasteners, ensuring that the products meet design requirements and usage standards. The degree of bending of the film fastener is a core physical indicator that determines its reliability, directly affecting its retention after folding, the smoothness of automated packaging lines, and the final adhesive effect. Currently, during the post-production quality inspection of film fasteners, when inspecting the internal crease quality of film fasteners with closed ring structures, it is necessary to first break the ring along the crease and flatten it at the inspection station. Uneven force during the breaking process can affect the inspection results. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a quality inspection device for film connectors after production.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a quality inspection device for membrane connectors after production, comprising a support frame, with legs fixedly connected to the bottom of the support frame, and a fixed platform fixedly connected to the support frame. A starting assembly for quality inspection of the membrane connectors is provided on the fixed platform. The starting assembly contains a trigger plate and a starting plate, which, through their cooperation, provide power for quality inspection of the membrane connectors. A first housing is provided within the starting assembly, and the first housing is fixedly connected to the bottom of the fixed platform. A stepper motor is located inside the first housing. A bearing is provided on the fixed platform, and a transmission column is fixedly connected to the inner ring of the bearing on the fixed platform. The output shaft of the stepper motor is fixedly connected to the transmission column, and the outer side of the transmission column is fixedly connected to the trigger plate. The support frame has a movable hole for placing a fixed sleeve, which is inserted into the movable hole of the support frame. A placement frame is fixedly connected to the top of the fixed sleeve, and two fixed posts are correspondingly inserted into the placement frame. A starter plate is movably connected to the outer side of each fixed post. A blocking block is provided on the top of each starter plate, and each blocking block is fixedly connected to the corresponding fixed post. A fixed sleeve is fixedly connected to the outer side of the moving rod. The trigger plate is tilted; when the trigger plate moves to a position corresponding to the starter plate, the trigger plate and starter plate are in contact. The starting assembly also includes a... Each positioning block is fixedly connected to the top of the support frame. The positioning block has a moving hole for placing a movable column, which is inserted into the moving hole. One end of the movable column is fixedly connected to a stop plate, and the end of the movable column away from the stop plate is fixedly connected to a limit frame. The top of the limit frame has two placement plates. Each fixed column passes through the limit frame and is fixedly connected to its corresponding placement plate. Each placement plate has a supplementary block fixedly connected to its top. A fixed plate is fixedly connected to the outside of the movable column. A first spring is sleeved on the movable column, with both ends of the first spring fixedly connected to the positioning block and the fixed plate, respectively. Two second springs are located inside the placement frame. Each second spring has its two ends fixedly connected to the corresponding fixed post and the inner wall of the placement frame. A bearing plate is fixedly connected to the bottom of each fixed post. Two trigger bars are fixedly connected to the outer side of the support frame. Each trigger bar is triangular. When the two bearing plates move to the position corresponding to the trigger bars, the bearing plates fit with the trigger bars. Each positioning frame is L-shaped. Each placement plate has an inclined slope to expand the membrane connection buckle. The placement frame and the limiting frame are semi-arc-shaped. The limiting frame and the placement frame have the same shape. When the moving post moves to the farthest end away from the trigger plate, the two fixed posts move to the two ends of the limiting frame and the placement frame.

[0005] With the above technical solution, when quality inspection of the membrane connector is required, the connecting part of the membrane connector is slid along the two inclined sections, so that the bottom of the circular part of the membrane connector slides to the top of the two placement plates, and the two supplementary blocks are in contact with the inner ring of the membrane connector. Then, the stepper motor is started, and the stepper motor drives the transmission column to rotate. When the transmission column rotates, it drives the trigger plate to rotate. When the inclined part of the trigger plate rotates to the position corresponding to the start plate, the trigger plate pushes the start plate to move. When the start plate moves, it drives the two fixed columns to move. When the fixed columns move, they drive the limit frame and the placement frame to move. When the placement frame moves, it drives the moving rod to move. When the limit frame moves, it drives the moving column to move. When the moving column moves, it drives the fixed plate to move. When the fixed plate moves, it drives the first spring to compress. The moving column drives the stop. The plate moves away from the positioning block, and while the limiting frame moves, the fixed post with bearing plate moves towards the trigger strip. When the bearing plate is in contact with the trigger strip, it moves towards both ends of the limiting frame. As the bearing plate moves, it drives the fixed post to move, compressing the two second springs. As the fixed post expands, it drives the two placement plates to expand. As the two placement plates expand, they drive the circular part of the membrane connector buckle to expand for yield degree detection. When the detection is completed, the stepper motor is started. The stepper motor drives the tilting part of the trigger plate to move away from the starter plate, causing the compressed first spring to rebound and reset the limiting frame. When the limiting frame resets, it drives the two fixed posts to reset. Then, the two compressed second springs rebound and cause the fixed posts to contract. Subsequently, the fixed posts drive the two placement plates to reset, thus completing the membrane connector buckle quality detection.

[0006] In a preferred embodiment of the present invention, a connecting frame is fixedly connected to the outer side of the fixed platform. The connecting frame is equipped with a conveying component for cooperating with the starting component. The conveying component contains a threaded post and a positioning platform. The cooperation between the threaded post and the positioning platform allows the membrane connector to be transferred. The top of the positioning platform is equipped with a positioning component for cooperating with the conveying component. The positioning component contains a positioning plate and a blocking plate. The cooperation between the positioning plate and the blocking plate allows the membrane connector to be fixed. The conveying component contains two bearing plates, each equipped with a bearing. The inner rings of the bearings on both bearing plates are fixedly connected to the threaded post. A positioning frame is fixedly connected to both ends of each bearing plate. A threaded block is threadedly connected to the outer side of the threaded post. One of the bearing plates is fixedly connected to... There is a second housing, inside which is a servo motor. The output shaft of the servo motor is fixedly connected to a threaded column. Each positioning frame has a fixedly connected limit column inside. Each limit column has a movable block movably connected to its outer side. Both movable blocks and the threaded block are fixedly connected to the positioning platform. The positioning assembly has two tension springs. The positioning platform has two placement holes for placing the tension springs. Each placement hole on the positioning platform has a movable block inserted into it. Each tension spring is located in the corresponding placement hole on the positioning platform. Both ends of each tension spring are fixedly connected to the corresponding movable block and the inner wall of the positioning platform, respectively. A positioning plate is fixedly connected to the top of each movable block. A blocking plate is fixedly connected to the outer side of the positioning platform. The outer side of each positioning plate is semi-circular.

[0007] With the above technical solution, when the membrane connector needs to be tested, the membrane connector is placed between two positioning plates, and then the two positioning plates move away from the positioning table. When the positioning plates move, they drive the moving blocks to move, and the moving blocks drive the tension springs to stretch. When the membrane connector is placed between the positioning plates, the two positioning plates fix the membrane connector. Then, the servo motor is started, and the servo motor drives the threaded column to rotate. When the threaded column rotates, it drives the threaded block to move towards the position of the placement plate. When the placement plate moves, it drives the two movable blocks to move. When the positioning plates move the membrane connector to the position corresponding to the placement plate, the blocking plate pushes the membrane connector to slide to the outside of the two placement plates.

[0008] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. This invention, through the setting of the starting component, the conveying component and the positioning component, and the cooperation of the placement plate and the supplementary block, adopts a detection method that expands synchronously from the inside of the ring. It can complete the yield degree detection without having to pry open and flatten the film connecting buckle along the crease, avoiding irreversible damage to the product caused by the pretreatment operation, eliminating the systematic error introduced by the detection itself, and ensuring that the detection results can accurately reflect the original quality state of the product.

[0009] 2. This invention, through the setting of a starting component, a conveying component, and a positioning component, achieves automatic product transfer by driving a threaded column with a servo motor, and completes automatic centering positioning of the product with a tension spring semi-arc positioning plate. The entire process of inspection can be completed without manual intervention, reducing the intensity of manual labor.

[0010] 3. By setting up the starting component, the conveying component and the positioning component, and by using the internal expansion cooperation between the placement plate and the supplementary block, the present invention adopts a non-destructive testing method to avoid visible damage such as base film breakage, adhesive layer peeling and surface scratches caused by the prying operation, thereby reducing the product scrap rate during the testing process.

[0011] 4. This invention precisely controls the power transmission during the detection process through the linkage between the trigger disc and the start disc. The triangular trigger bar drives the fixed column to achieve uniform and symmetrical expansion of the ring, reducing fluctuations in detection results caused by human error and improving the accuracy of quality judgment.

[0012] 5. This invention utilizes modular assembly of the placement plate and supplementary block, and the core detection mechanism adopts a replaceable design. It can quickly adapt to various specifications of film connectors by simply replacing the corresponding size parts, thereby improving the versatility of the device, shortening the production line changeover and debugging time, and meeting the needs of multi-variety production.

A fixed platform 4 is fixedly connected to the support frame 1, and a starting assembly for quality inspection of the membrane fasteners is provided on the fixed platform 4. The starting assembly contains a trigger plate 8 and a starting plate 17, which provide power for quality inspection of the membrane fasteners through their cooperation. A first housing 5 is provided inside the starting assembly and is fixedly connected to the bottom of the fixed platform 4. A stepper motor 6 is provided inside the first housing 5. A bearing is provided on the fixed platform 4, and a transmission column 7 is fixedly connected to the inner ring of the bearing. The output shaft of the stepper motor 6 is fixedly connected to the transmission column 7, and the outer side of the transmission column 7 is fixedly connected to the trigger plate 8. The connection includes a movable hole on the support frame 1 for placing the fixed sleeve 24. The fixed sleeve 24 is inserted into the movable hole of the support frame 1. A placement frame 15 is fixedly connected to the top of the fixed sleeve 24. Two fixed posts 19 are correspondingly inserted into the placement frame 15. A starting plate 17 is movably connected to the outside of each fixed post 19. A blocking block 18 is provided on the top of each starting plate 17. Each blocking block 18 is fixedly connected to the corresponding fixed post 19. The fixed sleeve 24 is fixedly connected to the outside of the moving rod 23. The trigger plate 8 is inclined. When the trigger plate 8 moves to the position corresponding to the starting plate 17, the trigger plate 8 and the starting plate 17 are in contact. The starting assembly also includes a positioning block 9, which is fixedly connected to the top of the support frame 1. Positioning block 9 has a movable hole for placing movable column 10. Movable column 10 is inserted into the movable hole of positioning block 9. One end of movable column 10 is fixedly connected to baffle plate 11. The end of movable column 10 away from baffle plate 11 is fixedly connected to limit frame 14. The top of limit frame 14 is provided with two placement plates 20. Each fixed column 19 passes through limit frame 14 and is fixedly connected to the corresponding placement plate 20. The top of each placement plate 20 is fixedly connected with supplementary block 21. Fixed plate 13 is fixedly connected to the outside of movable column 10. First spring 12 is sleeved on movable column 10. The two ends of first spring 12 are fixedly connected to positioning block 9 and fixed plate 13 respectively. The inside of placement frame 15 is provided with two second springs 16. Both ends are fixedly connected to the corresponding fixed posts 19 and the inner wall of the placement frame 15 respectively. A bearing plate 25 is fixedly connected to the bottom of each fixed post 19. Two trigger bars 22 are fixedly connected to the outer side of the support frame 1, and each trigger bar 22 is triangular. When the two bearing plates 25 move to the position corresponding to the trigger bars 22, the bearing plates 25 and trigger bars 22 are in contact. Each positioning frame 29 is L-shaped, and each placement plate 20 is provided with an inclined slope to expand the membrane connection buckle. The placement frame 15 and the limiting frame 14 are semi-arc-shaped, and the limiting frame 14 and the placement frame 15 have the same shape. When the moving post 10 moves to the farthest end away from the trigger plate 8, the two fixed posts 19 move to the two ends of the limiting frame 14 and the placement frame 15. like Figure 1, Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when a quality inspection of the membrane connector is required, the connecting part of the membrane connector is slid along the two inclined sections, and then the bottom of the circular part of the membrane connector slides to the top of the two placement plates 20, and the two supplementary blocks 21 are in contact with the inner ring of the membrane connector. Then, the stepper motor 6 is started, and the stepper motor 6 drives the transmission column 7 to rotate. When the transmission column 7 rotates, it drives the trigger disk 8 to rotate. When the inclined part of the trigger disk 8 rotates to the position corresponding to the starter disk 17, the trigger disk 8 pushes the starter disk 17 to move. When the starter disk 17 moves, it drives the two fixed columns 19 to move. When the fixed columns 19 move, they drive the limit frame 14 and the placement frame 15 to move. When the placement frame 15 moves, it drives the moving rod 23 to move. When the limit frame 14 moves, it drives the moving column 10 to move. When the moving column 10 moves, it drives the fixed plate 13 to move. When the fixed plate 13 moves, it drives the first spring 12 to compress. When the moving column 10 moves, it drives the stop plate 11 to move away from the starting plate 10. The positioning block 9 moves, and while the limiting frame 14 moves, the fixing post 19 moves with the bearing plate 25 toward the trigger bar 22. When the bearing plate 25 is in contact with the trigger bar 22, the bearing plate 25 moves toward both ends of the limiting frame 14. As the bearing plate 25 moves, it drives the fixing post 19 to move, and the two second springs 16 are compressed. As the fixing post 19 expands, it drives the two placement plates 20 to expand. As the two placement plates 20 expand, they drive the circular part of the membrane connector buckle to expand for yield degree detection. When the detection is completed, the stepper motor 6 is started. The stepper motor 6 drives the inclined part of the trigger disk 8 to move away from the starting disk 17. As a result, the compressed first spring 12 rebounds and drives the limiting frame 14 to reset. When the limiting frame 14 resets, it drives the two fixing posts 19 to reset. As a result, the two compressed second springs 16 rebound and drive the fixing post 19 to contract. Then the fixing post 19 drives the two placement plates 20 to reset, thus completing the membrane connector buckle quality detection.

[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8As shown, a connecting frame 3 is fixedly connected to the outer side of the fixed platform 4. The connecting frame 3 is equipped with a transmission component for cooperating with the starting component. The transmission component is equipped with a threaded post 28 and a positioning platform 33. The membrane connector can be transferred through the cooperation of the threaded post 28 and the positioning platform 33. The top of the positioning platform 33 is equipped with a positioning component for cooperating with the transmission component. The positioning component is equipped with a positioning piece 36 and a blocking plate 37. The membrane connector can be fixed through the cooperation of the positioning piece 36 and the blocking plate 37. The transmission component is equipped with two bearing plates 25. Each bearing plate 25 is equipped with a bearing. The inner ring of the bearings of both bearing plates 25 is fixedly connected to the threaded post 28. A positioning frame 29 is fixedly connected to both ends of each bearing plate 25. A threaded block 32 is threadedly connected to the outer side of the threaded post 28. A second housing 26 is fixedly connected to one of the bearing plates 25. The 6 has a servo motor 27 inside, and the output shaft of the servo motor 27 is fixedly connected to the threaded column 28. Each positioning frame 29 has a limiting column 30 fixedly connected inside, and each limiting column 30 has a movable block 31 movably connected to its outer side. The two movable blocks 31 and the threaded block 32 are fixedly connected to the positioning table 33. The positioning assembly has two tension springs 34 inside, and the positioning table 33 has two placement holes for placing the tension springs 34. Each placement hole on the positioning table 33 has a moving block 35 inserted into it.

Each moving block 35 has a positioning piece 36 fixedly connected to its top. The outer side of the positioning table 33 is fixedly connected to a blocking plate 37, and the outer side of each positioning piece 36 is semi-arc-shaped. like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, when the membrane connector needs to be tested, the membrane connector is placed between two positioning plates 36, and then the two positioning plates 36 move away from the positioning stage 33. When the positioning plates 36 move, they drive the moving block 35 to move, and the moving block 35 drives the tension spring 34 to stretch. When the membrane connector is placed between the positioning plates 36, the two positioning plates 36 fix the membrane connector, and then the servo motor 27 is started. The servo motor 27 drives the threaded column 28 to rotate. When the threaded column 28 rotates, it drives the threaded block 32 to move towards the position of the placement plate 20. When the placement plate 20 moves, it drives the two movable blocks 31 to move. When the positioning plates 36 move the membrane connector to the position corresponding to the placement plate 20, the blocking plate 37 pushes the membrane connector to slide to the outside of the two placement plates 20.

[0018] Working principle: Step 1, such as Figure 1, Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, when the membrane connector needs to be tested, the membrane connector is placed between two positioning plates 36, and then the two positioning plates 36 move away from the positioning table 33. When the positioning plates 36 move, they drive the moving block 35 to move. When the moving block 35 moves, it drives the tension spring 34 to stretch. When the membrane connector is placed between the positioning plates 36, the two positioning plates 36 fix the membrane connector. Then the servo motor 27 is started. The servo motor 27 drives the threaded column 28 to rotate. When the threaded column 28 rotates, it drives the threaded block 32 to move towards the position of the placement plate 20. When the placement plate 20 moves, it drives the two movable blocks 31 to move. When the positioning plates 36 drive the membrane connector to the position corresponding to the placement plate 20, the blocking plate 37 pushes the membrane connector to slide to the outside of the two placement plates 20. Step 2, as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, when a quality inspection of the membrane connector is required, the connecting part of the membrane connector is slid along the two inclined sections, and then the bottom of the circular part of the membrane connector slides to the top of the two placement plates 20, and the two supplementary blocks 21 are in contact with the inner ring of the membrane connector. Then, the stepper motor 6 is started, and the stepper motor 6 drives the transmission column 7 to rotate. When the transmission column 7 rotates, it drives the trigger disk 8 to rotate. When the inclined part of the trigger disk 8 rotates to the position corresponding to the starter disk 17, the trigger disk 8 pushes the starter disk 17 to move. When the starter disk 17 moves, it drives the two fixed columns 19 to move. When the fixed columns 19 move, they drive the limit frame 14 and the placement frame 15 to move. When the placement frame 15 moves, it drives the moving rod 23 to move. When the limit frame 14 moves, it drives the moving column 10 to move. When the moving column 10 moves, it drives the fixed plate 13 to move. When the fixed plate 13 moves, it drives the first spring 12 to compress. When the moving column 10 moves, it drives the stop plate 11 to move away from the starting plate 10. The positioning block 9 moves, and while the limiting frame 14 moves, the fixing post 19 moves with the bearing plate 25 toward the trigger bar 22. When the bearing plate 25 is in contact with the trigger bar 22, the bearing plate 25 moves toward both ends of the limiting frame 14. As the bearing plate 25 moves, it drives the fixing post 19 to move, and the two second springs 16 are compressed. As the fixing post 19 expands, it drives the two placement plates 20 to expand. As the two placement plates 20 expand, they drive the circular part of the membrane connector buckle to expand for yield degree detection. When the detection is completed, the stepper motor 6 is started. The stepper motor 6 drives the inclined part of the trigger disk 8 to move away from the starting disk 17. As a result, the compressed first spring 12 rebounds and drives the limiting frame 14 to reset. When the limiting frame 14 resets, it drives the two fixing posts 19 to reset. As a result, the two compressed second springs 16 rebound and drive the fixing post 19 to contract. Then the fixing post 19 drives the two placement plates 20 to reset, thus completing the membrane connector buckle quality detection.
