Abstract

A fixture closing device includes a support frame, a stop mechanism, a carrying and moving mechanism, and a closing mechanism. The stop mechanism is located on the support frame and stops the fixture as it moves to the support frame. The carrying and moving mechanism is located on the support frame and to one side of the stop mechanism, supporting the fixture stopped by the stop mechanism and moving the fixture. The closing mechanism is located on the support frame and opposite to the carrying and moving mechanism, pushing the cover plate of the fixture to rotate so that the cover plate presses onto the product carried by the fixture. This fixture closing device, by incorporating the stop mechanism and the carrying and moving mechanism, facilitates the movement of the fixture conveyed on the transmission line to a predetermined operating position. By using the closing mechanism to push the cover plate of the fixture to rotate, it automatically pushes the cover plate onto the product to complete the fixture closing operation, improving the efficiency of fixture closing and reducing labor costs. Furthermore, the automation method ensures high stability during fixture closing, thereby improving the yield rate during product assembly.

Description

Technical Field

[0001] This application relates to the field of automatic jig operation device technology, specifically to a jig closing device. Background Technology

[0002] Currently, in the assembly process of products such as laptop keyboards and mobile phone casings, the product is typically placed on the base of a fixture for positioning. Then, magnetic pieces and other components are placed on the fixture's cover plate. The cover plate is then manually flipped to close the fixture, pressing the components onto the corresponding positions on the product, thus facilitating assembly operations such as welding, baking, and bonding. However, manually flipping the cover plate to close the fixture is inefficient, requiring multiple people to operate the fixture on the conveyor line, resulting in high labor costs. In addition, the assembly quality of manual operations is low and inconsistent. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0078] Please see Figure 1 This application provides a fixture lid-closing device 100, which includes a support frame 10, a stop mechanism 20, a load-bearing moving mechanism 30, and a lid-closing mechanism 40.

[0079] Please see Figure 1 and Figure 2In this embodiment, the fixture closing device 100 is used to push the cover plate 220 of the fixture 200 to rotate, so that when the cover plate 220 is closed, it causes the assembly 300 to press onto the corresponding position of the product (not shown), thereby facilitating assembly operations such as welding, baking, and bonding of the assembly 300 and the product. The product can be a laptop keyboard, a mobile phone casing, etc., and the assembly 300 can be a magnetic sheet, a snap-fit ​​spring, etc. For ease of understanding and explanation, this embodiment uses a laptop keyboard as the product, a magnetic sheet as the assembly 300, and the fixture 200 including a base 210 and multiple cover plates 220, with the multiple cover plates 220 rotatably mounted on the base 210, as an example. Obviously, this is not a limitation of this embodiment.

[0080] In this embodiment, a stop mechanism 20 is provided on the support frame 10. The stop mechanism 20 is used to stop the fixture 200 from moving to the support frame 10. Multiple fixtures 200 are transported on a transmission line (not shown). When a product is placed on the base 210 of the fixture 200 for positioning, and the assembly 300 is placed at the designated position on the cover plate 220 and glue is applied using a dispensing machine (not shown), the transmission line moves the fixture 200 to the support frame 10, and the stop mechanism 20 stops the fixture 200.

[0081] The carrying and moving mechanism 30 is disposed on the support frame 10 and located on one side of the stop mechanism 20. The carrying and moving mechanism 30 is used to carry the fixture 200 stopped by the stop mechanism 20 and drive the fixture 200 to move. The carrying and moving mechanism 30 can be disposed in front of the stop mechanism 20 and below the transmission line. When the stop mechanism 20 stops the fixture 200, the carrying and moving mechanism 30 lifts the fixture 200 off the transmission line and carries the fixture 200.

[0082] The closing mechanism 40 is mounted on the support frame 10 and is positioned opposite the carrying and moving mechanism 30. The closing mechanism 40 is used to push the cover plate 220 of the fixture 200 to rotate, so that the cover plate 220 presses onto the product carried by the fixture 200. Specifically, when the carrying and moving mechanism 30 lifts the fixture 200, the closing mechanism 40 moves toward the cover plate 220 and pushes the cover plate 220 to rotate, thereby causing the cover plate 220 to drive the assembly 300 to press onto the corresponding position of the product.

[0083] In this embodiment, the fixture 200 has multiple cover plates 220. These multiple cover plates 220 are used to press different sizes of assembly parts 300 onto different positions on the inner wall of the product, thereby facilitating the subsequent placement of the fixture 200, the product, and the assembly parts 300 into an oven to cure the adhesive on the assembly parts 300, thus achieving the assembly operation between the assembly parts 300 and the product. Correspondingly, there are also multiple closing mechanisms 40. These multiple closing mechanisms 40 are spaced apart on the support frame 10 and correspond one-to-one with each of the multiple cover plates 220. Each of the multiple closing mechanisms 40 is used to push the corresponding cover plate 220 to rotate.

[0084] Please see Figure 1 In this embodiment, the support frame 10 includes a base plate 11, a top plate 12, a lifting drive component 13, a support rod 14, and a lifting plate 15. A stop mechanism 20 and a load-bearing moving mechanism 30 are both located on the base plate 11; the top plate 12 is spaced apart from the base plate 11, and the lifting drive component 13 is located on the top plate 12; both ends of the support rod 14 are connected to the base plate 11 and the top plate 12 respectively, and the support rod 14 is used to support the base plate 11 and the top plate 12; the lifting plate 15 is slidably located on the support rod 14 and connected to the lifting drive component 13; a cover-closing mechanism 40 is located on the lifting plate 15, and the lifting plate 15 is used to drive the cover-closing mechanism 40 closer to or further away from the load-bearing moving mechanism 30 under the drive of the lifting drive component 13, so that when the cover-closing mechanism 40 approaches the load-bearing moving mechanism 30, it pushes the cover plate 220 to rotate.

[0085] Specifically, the lifting drive component 13 can be a telescopic cylinder, and there are multiple support rods 14. These support rods 14 are spaced apart and pass through the lifting plate 15. Multiple closing mechanisms 40 are spaced apart on the side of the lifting plate 15 facing the base plate 11. When the carrying and moving mechanism 30 lifts the fixture 200, the lifting drive component 13 drives the multiple closing mechanisms 40 to move towards the carrying and moving mechanism 30 via the lifting plate 15, thus facilitating the multiple closing mechanisms 40 to push their respective cover plates 220 to rotate. Furthermore, after the multiple closing mechanisms 40 push their respective cover plates 220 to press the assembly 300 onto the product, the lifting drive component 13 drives the multiple closing mechanisms 40 away from the carrying and moving mechanism 30 via the lifting plate 15, thereby preventing interference between the cover mechanism 40 and the fixture 200 when the transmission line continues to move the fixture 200.

[0086] In this embodiment, the support frame 10 also includes a limiting buffer assembly 16. The limiting buffer assembly 16 is disposed on the base plate 11 and extends to the lifting plate 15. The limiting buffer assembly 16 is used to elastically abut against the lifting plate 15 when the lifting drive member 13 drives the lifting plate 15 to approach the bearing moving mechanism 30, so as to limit the moving distance of the lifting plate 15 and buffer the lifting plate 15.

[0087] Specifically, there are multiple limiting buffer components 16, which are spaced apart on the base plate 11. Each limiting buffer component 16 includes a fixed rod 161 and a limiting buffer element 162. One end of the fixed rod 161 is connected to the base plate 11, and the other end of the fixed rod 161 extends toward the lifting plate 15. The limiting buffer element 162 can be a hydraulic buffer, which is located at the other end of the fixed rod 161. When the lifting drive component 13 drives the lifting plate 15 to approach the bearing moving mechanism 30, the limiting buffer element 162 abuts against the lifting plate 15, thereby limiting and buffering the lifting plate 15.

[0088] Thus, by setting the limiting buffer 162 to limit the movement distance of the lifting plate 15 and buffer the lifting plate 15, it is beneficial to improve the accuracy of the lifting drive 13 when it drives multiple closing mechanisms 40 to move to a predetermined position close to the bearing moving mechanism 30 through the lifting plate 15. It can also reduce the vibration generated after the lifting plate 15 reaches the predetermined position, thereby improving the accuracy of the closing mechanism 40 when it pushes the cover plate 220 to rotate.

[0089] In this embodiment, the fixture closing device 100 also includes a controller 80, which is disposed on the top plate 12 and electrically connected to the lifting drive 13, the stop mechanism 20, the load-bearing moving mechanism 30 and the closing mechanism 40, thereby controlling the operation of the lifting drive 13, the stop mechanism 20, the load-bearing moving mechanism 30 and the closing mechanism 40.

[0090] In this embodiment, the support frame 10 also includes a cover-closing sensor 17. The cover-closing sensor 17 is disposed on the lifting plate 15 and electrically connected to the controller 80. The cover-closing sensor 17 can be a functional sensor that can sense the position of an object, such as a photoelectric sensor or an acoustic sensor. The cover-closing sensor 17 is used to sense whether the cover plate 220 is closed. When the cover-closing sensor 17 senses that the cover plate 220 is closed, the cover-closing sensor 17 sends sensing information to the controller 80, so that the lifting drive 13 can drive the lifting plate 15 and the cover-closing mechanism 40 back to their original positions under the control of the controller 80.

[0091] In this embodiment, the support frame 10 further includes a connecting plate 18, which is connected to the top plate 12 and passes through the lifting plate 15. There can be two connecting plates 18. The fixture closing device 100 also includes a first scanning element 50 and a second scanning element 60. The first scanning element 50 and the second scanning element 60 are respectively located at the ends of the two connecting plates 18 away from the top plate 12, and both are electrically connected to the controller 80. The first scanning element 50 is used to scan the identification code of the fixture 200, and the second scanning element 60 is used to scan the identification code of the product. The first scanning element 50 and the second scanning element 60 respectively send the scanned identification code of the fixture 200 and the product identification code to the controller 80 for binding, thereby facilitating traceability of the product assembly process. The identification code can be a barcode, QR code, etc.

[0092] In this embodiment, the fixture closing device 100 further includes a barcode scanning shielding component 70. The barcode scanning shielding component 70 includes a fixed plate 71, a barcode scanning shielding drive 72, and a shielding plate 73. The fixed plate 71 passes through the lifting plate 15 and is connected to the side of the top plate 12 facing the bottom plate 11. The fixed plate 71 is located on one side of the second scanning element 60. The barcode scanning shielding drive 72 is disposed on the fixed plate 71 and connected to the controller 80. The shielding plate 73 is connected to the barcode scanning shielding drive 72, so that it moves towards the second scanning element 60 and shields the second scanning element 60 under the drive of the barcode scanning shielding drive 72. After the second scanning element 60 scans the product's identification code once, the barcode scanning shielding drive 72 drives the shielding plate 73 to shield the second scanning element 60, preventing the second scanning element 60 from repeatedly scanning the product's identification code and thus preempting the controller 80's computing resources. This helps improve the stability of the fixture closing device 100 during operation.

[0093] In this embodiment, the fixture closing device 100 also includes a safety detection sensor 90. The safety detection sensor 90 can be mounted on the fixed rod 161 or the support rod 14. The safety detection sensor 90 can be a functional sensor for sensing the position of an object, such as a light sensor. The safety detection sensor 90 is electrically connected to the controller 80. When an operator inserts their body into the fixture closing device 100, the safety detection sensor 90 sends sensing information to the controller 80. The controller 80 then controls the entire fixture closing device 100 to stop moving, thereby reducing the risk of injury to the operator.

[0094] Please see Figure 1 and Figure 3In this embodiment, the stop mechanism 20 includes a stop drive member 21, a fixing block 22, and a stop assembly 23. The stop drive member 21 is disposed on the bottom plate 11 of the support frame 10 and located on one side of the carrying moving mechanism 30; the fixing block 22 is disposed on the side wall of the stop drive member 21 and extends towards the top plate 12; the stop assembly 23 is rotatably disposed on the fixing block 22 and connected to the output end of the stop drive member 21. Under the drive of the stop drive member 21, one end of the stop assembly 23 swings toward or away from the fixing block 22, and when one end of the stop assembly 23 moves away from the fixing block 22, the stop fixture 200 is stopped.

[0095] Specifically, the stop drive component 21 can be a telescopic cylinder, and the stop drive component 21 is electrically connected to the controller 80. When the transmission line drives the fixture 200 to move between the bottom plate 11 and the top plate 12, the stop drive component 21 drives the stop assembly 23 to rotate, thereby moving the end of the stop assembly 23 near the bearing moving mechanism 30 away from the fixed block 22 to stop the fixture 200; when the cover closing mechanism 40 pushes the cover plate 220 to rotate, causing the cover plate 220 to carry the assembly 300 to cover the product, the stop drive component 21 drives the stop assembly 23 to return to its original position, thereby moving the end of the stop assembly 23 near the bearing moving mechanism 30 closer to the fixed block 22 to avoid the fixture 200, thus facilitating the transmission line to move the fixture 200 to the next process.

[0096] In this embodiment, the stop assembly 23 includes a stop block 231 and a stop wheel 232. The stop block 231 is rotatably mounted on the fixed block 22, one end of the stop block 231 is connected to the output end of the stop drive member 21, and the other end of the stop block 231 extends toward the bearing moving mechanism 30. The stop wheel 232 is rotatably mounted on the other end of the stop block 231, and the stop wheel 232 is used to rotate and abut against the fixture 200 under the drive of the stop block 231 to stop the fixture 200. The stop wheel 232 can be made of elastic material such as rubber. When the stop drive member 21 drives the stop block 231 to rotate and causes the stop wheel 232 to abut against the fixture 200, the stop wheel 232 can disperse the impact force of the fixture 200 by rotating, thereby helping to reduce the damage to the fixture 200 when stopping it. In addition, when the carrier moving mechanism 30 lifts the fixture 200 off the transmission line, the stop wheel 232 reduces the friction between itself and the fixture 200 by rotating, which helps the carrier moving mechanism 30 to lift the fixture 200 quickly.

[0097] Please see Figure 1 and Figure 4In this embodiment, the supporting moving mechanism 30 includes a moving drive component 31, a sliding rod 32, and a supporting plate 33. The moving drive component 31 is disposed on the bottom plate 11 of the support frame 10; the sliding rod 32 is slidably inserted into the bottom plate 11 of the support frame 10 and located on one side of the stop mechanism 20; the supporting plate 33 is disposed on the sliding rod 32 and located between the bottom plate 11 and the top plate 12. The supporting plate 33 is directly opposite the closing mechanism 40 and connected to the moving drive component 31. The supporting plate 33 is used to support the fixture 200 stopped by the stop mechanism 20 under the drive of the moving drive component 31 and to lift the fixture 200.

[0098] Specifically, the moving drive component 31 can be a telescopic cylinder, and there are multiple sliding rods 32, which are spaced apart and inserted into the base plate 11 and extend towards the lifting plate 15. When the stop wheel 232 of the stop mechanism 20 stops the fixture 200, the moving drive component 31 drives the bearing plate 33 and the multiple sliding rods 32 to move towards the lifting plate 15, so that the bearing plate 33 lifts the fixture 200 and supports the fixture 200, preventing the fixture 200 from shaking under the drive of the transmission line when the cover closing mechanism 40 pushes the cover plate 220 to rotate, thereby improving the stability and accuracy of the cover closing mechanism 40 when pushing the cover plate 220 to rotate.

[0099] In this embodiment, the carrying and moving mechanism 30 further includes an assembly plate 34 and a first limiting member 35. The assembly plate 34 is disposed at the end of the sliding rod 32 away from the lifting plate 15, and both ends of the assembly plate 34 can be connected to two adjacent sliding rods 32. The first limiting member 35 is disposed on the assembly plate 34 and extends towards the base plate 11. The first limiting member 35 can also be a hydraulic damper. When the moving drive member 31 drives the carrying plate 33 and multiple sliding rods 32 to move towards the lifting plate 15, the first limiting member 35 abuts against the base plate 11 to limit the moving distance of the carrying plate 33, thereby improving the accuracy of the carrying plate 33 moving to the predetermined position when the moving drive member 31 drives the carrying plate 33 to move towards the closing mechanism 40.

[0100] In this embodiment, the carrying and moving mechanism 30 further includes a second limiting member 36, which is disposed on the base plate 11 and extends towards the carrying plate 33. Multiple second limiting members 36 may be provided and spaced apart. The second limiting member 36 may also be a hydraulic damper. When the moving drive member 31 drives the carrying plate 33 and multiple sliding members back to their original positions, the second limiting member 36 abuts against the carrying plate 33 and limits the movement distance of the carrying plate 33, thereby improving the accuracy of the moving drive member 31 driving the carrying plate 33 back to its original position.

[0101] Please see Figure 2 and Figure 4In this embodiment, the supporting moving mechanism 30 further includes a positioning block 37 and a side-push positioning component 38. The positioning block 37 is disposed on the side of the supporting plate 33 opposite to the bottom plate 11, and is used to insert into the positioning hole 230 of the fixture 200 to position the fixture 200 on the supporting plate 33. The side-push positioning component 38 is disposed on the supporting plate 33 and located on one side of the positioning block 37, and is used to push the fixture 200 to move on the supporting plate 33 so that the positioning block 37 is inserted into the positioning hole 230 of the fixture 200.

[0102] Thus, by setting the positioning block 37 to position the fixture 200 on the support plate 33, the position of the fixture 200 relative to the closing mechanism 40 is kept uniform, which helps improve the accuracy of the closing mechanism 40 when it pushes the cover plate 220 to rotate. By setting the side-push positioning component 38 to push the fixture 200 to move so that the positioning block 37 can be inserted into the positioning hole 230 of the fixture 200, the situation where the fixture 200 cannot be positioned when it slides on the support plate 33 relative to the positioning block 37 can be avoided, thereby improving the accuracy of the positioning block 37 in positioning the fixture 200.

[0103] In this embodiment, there can be multiple side-push positioning components 38, arranged around the edge of the support plate 33. Each side-push positioning component 38 includes a side-push drive member 381 and a side-push plate 382. The side-push drive member 381 is located at the edge of the support plate 33 and electrically connected to the controller 80. The side-push drive member 381 can be a telescopic cylinder. The side-push plate 382 is connected to the side-push drive member 381 and moves towards the support plate 33 under the drive of the side-push drive member 381, thereby pushing the fixture 200 set on the support plate 33 to a predetermined position to cooperate with the positioning block 37. Thus, by setting the side-push positioning component 38 to include a side-push drive member 381 and a side-push plate 382, ​​the structure is simple and it is beneficial to improve the accuracy of pushing the fixture 200 to the predetermined position to cooperate with the positioning block 37.

[0104] Please see Figure 1 and Figure 5 In this embodiment, the lid closing mechanism 40 includes a translation drive 41, a movable seat 42, a lid closing drive 43, and a lid closing push assembly 44. The translation drive 41 is disposed on the lifting plate 15 of the support frame 10; the movable seat 42 is connected to the translation drive 41 and faces the bearing plate 33 of the carrying moving mechanism 30, so as to move closer to or away from the carrying moving mechanism 30 under the drive of the translation drive 41; the lid closing drive 43 is disposed on the movable seat 42; the lid closing push assembly 44 is connected to the lid closing drive 43, so as to push the lid plate 220 to rotate under the drive of the lid closing drive 43.

[0105] Specifically, both the translation drive 41 and the lid-closing drive 43 can be telescopic cylinders. When the lifting drive 13 drives the lid-closing mechanism 40 to move towards the supporting moving mechanism 30 via the lifting plate 15, the translation drive 41 drives the moving seat 42 to move laterally away from the supporting moving mechanism 30, thereby preventing the moving seat 42 from interfering with the lid 220 by driving the lid-closing drive 43 and the lid-closing pushing assembly 44. After the lid-closing drive 43 and the lid-closing pushing assembly 44 move to the predetermined position, the lid-closing drive 43 drives the lid-closing pushing assembly 44 to move towards the lid 220 to push the lid 220 to rotate. Thus, by setting the translation drive 41 to move the moving seat 42 closer to or further away from the bearing moving mechanism 30, the moving seat 42 can move the cover-closing drive 43 and the cover-closing push assembly 44 to a predetermined position and avoid the cover plate 220. By setting the cover-closing drive 43 to drive the cover-closing push assembly 44 to push the cover plate 220 to rotate, the cover plate 220 can press the assembly 300 onto the product more quickly and stably, thereby improving the efficiency of the closing fixture 200 and the yield rate during product assembly.

[0106] In this embodiment, the lid-closing pushing assembly 44 includes a pushing block 441 and a pushing wheel 442. The pushing block 441 is connected to the lid-closing driving member 43 and moves towards the lid plate 220 under the drive of the lid-closing driving member 43; the pushing wheel 442 is rotatably disposed on the side of the pushing block 441 facing the carrying moving mechanism 30, and the pushing wheel 442 is used to rotate and abut against the lid plate 220 under the drive of the pushing block 441 and push the lid plate 220 to rotate.

[0107] Specifically, the push wheel 442 can be made of elastic materials such as rubber. When the cover closing drive member 43 drives the push wheel 442 to abut against the cover plate 220 through the push block 441, the push wheel 442 will rotate under the squeezing force of the cover plate 220, which helps to reduce the friction between the cover plate 220 and the push wheel 442 when rotating, thereby improving the efficiency of the closing fixture 200 and reducing the wear on the cover plate 220.

[0108] In this embodiment, the closing mechanism 40 further includes a buffer drive 45, a sliding seat 46, a push rod 47, and an elastic member 48. The buffer drive 45 is disposed on the movable seat 42 and spaced apart from the closing drive 43; the sliding seat 46 is slidably disposed on the movable seat 42 and connected to the buffer drive 45, so as to approach or move away from the support plate 33 of the carrying movable mechanism 30 under the drive of the buffer drive 45; the push rod 47 is slidably inserted into the sliding seat 46 and extends away from the movable seat 42, and the push rod 47 is used to abut against the cover plate 220 when the cover plate 220 rotates, and slides on the sliding seat 46 under the pushing action of the cover plate 220; the two ends of the elastic member 48 abut against the sliding seat 46 and the push rod 47 respectively, and the elastic member 48 is used to elastically support the push rod 47 when the cover plate 220 pushes the push rod 47 to slide, so as to slow down the speed at which the cover plate 220 presses onto the product.

[0109] Specifically, the buffer drive 45 is electrically connected to the controller 80. The buffer drive 45 can also be a telescopic cylinder, and the elastic element 48 can be a spring. The elastic element 48 is sleeved on the push rod 47, and its two ends abut against the push rod 47 and the sliding seat 46, respectively. When the push wheel 442 pushes the cover plate 220 to rotate, the buffer drive 45 drives the sliding seat 46 to move towards the fixture 200. Driven by the sliding seat 46, the push rod 47 passes through the side wall of the base 210 and abuts against the cover plate 220. The cover plate 220 slides by squeezing the push rod 47 under its own weight, thereby compressing the elastic element 48. Then, the cover plate 220 drives the assembly 300 to slowly close onto the product. In this way, by setting the push rod 47 and the elastic element 48 to cooperate to slow down the speed at which the cover plate 220 closes onto the product, the situation where the cover plate 220 drives the assembly 300 to close onto the product too quickly and damages the product is avoided, thereby improving the yield rate during product assembly.

[0110] In this embodiment, the closing mechanism 40 also includes a position sensor 49, which is disposed on the sliding seat 46 and corresponds to the top rod 47. The position sensor 49 is connected to the controller 80. The position sensor 49 can be a functional sensor that can sense the position of an object, such as a contact sensor or a photoelectric sensor. The position sensor 49 is used to sense the position information of the top rod 47, thereby determining whether the cover plate 220 is closed in place based on the position information of the top rod 47.

[0111] The process by which the fixture closing device 100 pushes the cover plate 220 on the fixture 200 to close in this embodiment includes:

[0112] The transmission line drives the fixture 200 to move between the bottom plate 11 and the top plate 12. The stop drive 21 drives the stop block 231 to rotate and makes the stop wheel 232 move away from the fixed block 22. The fixed block 22 stops the fixture 200.

[0113] The moving drive component 31 drives the support plate 33 to lift the fixture 200, and the side push positioning component 38 and the positioning block 37 cooperate to position the fixture 200.

[0114] The first scanner 50 and the second scanner 60 scan the identification code of the fixture 200 and the product identification code respectively, and send the scanned identification code of the fixture 200 and the product identification code to the controller 80 for binding.

[0115] The lifting drive 13 drives the lifting plate 15 and the closing mechanism 40 to move toward the support plate 33. The translation drive 41 drives the moving seat 42 to move laterally so that the closing drive 43 and the closing push assembly 44 avoid the cover plate 220. The closing drive 43 drives the push block 441 to move toward the cover plate 220 so that the push wheel 442 pushes the cover plate 220 to rotate. The buffer drive 45 drives the sliding seat 46 to move toward the fixture 200 so that the top rod 47 cooperates with the elastic member 48 to slow down the speed at which the cover plate 220 presses onto the product.

[0116] When the closing sensor 17 and the positioning sensor 49 detect that the cover plate 220 is closed, the controller 80 controls the lifting drive 13, the stop mechanism 20, the carrying moving mechanism 30 and the closing mechanism 40 to return to their original positions, and the transmission line drives the fixture 200 to move to the next process.

[0117] In summary, the fixture closing device 100 of this application embodiment stops the fixture 200 moving to the support frame 10 by setting a stop mechanism 20, and lifts and carries the fixture 200 by setting a carrying and moving mechanism 30, which facilitates the movement of the fixture 200 conveyed on the transmission line to a predetermined operating position. By setting a closing mechanism 40 to push the cover plate 220 of the fixture 200 to rotate, the cover plate 220 is automatically pushed to press onto the product to complete the closing operation of the fixture 200, which improves the efficiency of closing the fixture 200 and reduces labor costs. In addition, the high stability of closing the fixture 200 through automation can effectively reduce the occurrence of incomplete closing of the fixture 200 and scratches on the product, thereby improving the yield rate during product assembly.
