Description

Technical Field

[0001] This application relates to the field of circuit board manufacturing, and in particular to an FPC quick-change depaneling machine. Background Technology

[0002] Flexible printed circuit boards (FPCs), due to their excellent flexibility and thinness, have become key components for achieving high-density interconnection and three-dimensional assembly in modern consumer electronics, automotive electronics, and other fields. On automated assembly lines, individual flexible printed circuit boards typically need to be removed from the incoming substrate and precisely transferred to a dedicated assembly tray so that the tray can carry the flexible printed circuit board into subsequent automated mounting, soldering, or inspection processes.

[0003] Currently, the operation of picking up and placing flexible circuit boards from the substrate onto the tray mainly relies on manual labor. However, this method has significant drawbacks: First, manual operation is inefficient and has become a bottleneck restricting the improvement of the overall production line capacity; second, FPCs are thin and flexible, and manual handling is prone to bending, scratching, or even damaging the electrical performance of the boards due to improper handling force or angle, directly affecting the product yield. Summary of the Invention

[0004] In order to improve the efficiency and yield of flexible circuit boards from substrate to tray, this application provides an FPC quick-change depaneling machine.

[0005] The FPC quick-change depaneling machine provided in this application adopts the following technical solution:

[0006] An FPC quick-change depaneling machine includes a chassis, a main conveying mechanism disposed within the chassis, a base plate movably mounted on the main conveying mechanism, and a substrate placed on the base plate; a first limiting mechanism located within the main conveying mechanism, used to clamp and fix the base plate and drive the base plate to move; a lifting mechanism disposed at the moving end of the first limiting mechanism and used to lift the flexible circuit board within the substrate; a secondary conveying mechanism, on which a tray is movably mounted; a second limiting mechanism located within the secondary conveying mechanism, used to clamp and fix the tray and drive the tray to move; and a gripping mechanism that grips the flexible circuit board on the base plate and places it into the tray.

[0007] By adopting the above technical solution, during the quick replacement of flexible circuit boards, the substrate is first mounted on the base plate, then the base plate is sent into the main conveying mechanism, and the empty tray is sent into the auxiliary conveying mechanism. A first limiting mechanism fixes the base plate to the main conveying mechanism, and a second limiting mechanism fixes the tray to the auxiliary conveying mechanism. A lifting mechanism lifts the flexible circuit board, and a gripping mechanism then grips the lifted flexible circuit board and places it in the tray. Subsequently, the first and second limiting mechanisms move the base plate and tray, and the gripping mechanism performs the pick-and-place operation of the flexible circuit board again. With this setup, the gripping and placement of flexible circuit boards are fully automated, thereby greatly improving the efficiency and yield of flexible circuit board handling.

[0008] Preferably, the main conveying mechanism includes a main support, a main conveyor belt, and a main drive component. The main support is disposed inside a housing, the main conveyor belt is rotatably mounted on the main support, and the main drive component is disposed on the main support and is used to drive the main conveyor belt to rotate. The auxiliary conveying mechanism includes a secondary support, a secondary conveyor belt, and a secondary drive component. The secondary support is disposed inside a housing, the secondary conveyor belt is rotatably mounted on the secondary support, and the secondary drive component is disposed on the secondary support and is used to drive the secondary conveyor belt to rotate.

[0009] By adopting the above technical solution, the base plate is fed onto the main support, the main drive unit drives the main conveyor belt to rotate, the main conveyor belt drives the base plate to move on the main support, the pallet is fed onto the secondary support, the secondary drive unit drives the secondary conveyor belt to rotate, the secondary conveyor belt drives the pallet to move on the secondary support.

[0010] Preferably, the first limiting mechanism includes a first driving member, a movable seat, two first baffles, a first lifting member, and a top plate. The movable seat is slidably disposed inside the chassis. The first driving member is disposed inside the chassis and is used to drive the movable seat to slide. The lifting mechanism is disposed on the movable seat. The two first baffles are disposed on both sides of the movable seat and located above the bottom plate. The bottom of the first baffle is provided with a positioning pin. The bottom plate is provided with a positioning hole, and the positioning pin is inserted into the positioning hole. The two first lifting members are disposed on both sides of the movable seat. The two top plates are disposed on the two first lifting members and located below the bottom plate.

[0011] By adopting the above technical solution, after the main conveying mechanism moves the base plate to the designated position, the two first lifting members move the top plate upward. The top plate pushes the base plate upward to disengage from the main conveying mechanism. The top plate and the first baffle clamp and fix the base plate vertically. The positioning pin is inserted into the positioning hole and fixes the base plate horizontally, making the gripping mechanism more accurate when gripping the flexible circuit board. At the same time, the first driving member drives the base plate to move through the moving seat, which facilitates the gripping of subsequent flexible circuit boards.

[0012] Preferably, the lifting mechanism includes a three-axis moving assembly and a top head. The three-axis moving assembly is mounted on a moving base, and the top head is detachably mounted on the moving end of the three-axis moving assembly. The base plate has multiple insertion holes corresponding to the flexible circuit board. The top head is inserted into the insertion holes and lifts the flexible circuit board inside the base plate.

[0013] By adopting the above technical solution, the three-axis moving mechanism drives the top head to move freely in three-dimensional space. After the top head rises and moves, it is inserted into the insertion hole of the base plate, thereby lifting the flexible circuit board from the substrate.

[0014] Preferably, the second limiting mechanism includes a second driving member, a translation plate, a second lifting member, a tray, two second baffles, a first translation member, and clamping plates. The translation plate is slidably disposed within the chassis. The second driving member is disposed within the chassis and is used to drive the translation plate to move. The tray is lifted and disposed on the translation plate and located below the tray. The second lifting member is disposed on the translation plate and is used to drive the tray to move up and down. The two second baffles are disposed on both sides of the translation plate and located above the tray. The two clamping plates are slidably disposed at both ends of the translation plate and located on both sides of the tray. The two first translation members are disposed on the translation plate and are used to drive the two clamping plates to move.

[0015] By adopting the above technical solution, after the main conveying mechanism moves the pallet to the designated position, the second lifting component moves the pallet upward, and the pallet pushes the pallet upward to disengage from the auxiliary conveying mechanism. The pallet and the second baffle clamp the pallet vertically, and the two first translation components move the two clamping plates horizontally to clamp the pallet, making the gripping mechanism more accurate when placing flexible circuit boards. At the same time, the second driving component moves the pallet through the translation plate, which facilitates the subsequent placement of flexible circuit boards.

[0016] Preferably, the gripping mechanism includes a gantry frame, a third driving component, a fourth driving component, a third lifting component, a suction cup base, and an elastic component. The gantry frame is disposed inside the chassis, the third driving component is disposed on the gantry frame, the fourth driving component is disposed at the translation end of the third driving component, the third lifting component is disposed at the lifting end of the fourth driving component, the suction cup base is slidably disposed at the lifting end of the third lifting component, and the elastic component is disposed on the suction cup base and abuts against the lifting end of the third lifting component.

[0017] By adopting the above technical solution, the third and fourth drive components on the gantry frame drive the suction cup seat to move horizontally and vertically through the third lifting component. When the suction cup seat moves above the base plate, the third lifting component drives the suction cup seat to move downward, so that the bottom of the suction cup seat abuts against the flexible circuit board. When the lifting mechanism lifts the flexible circuit board in the substrate, the flexible circuit board drives the suction cup seat to move upward. The suction cup seat pushes the elastic component to contract and deform, so that the flexible circuit board presses against the suction cup seat. Then the suction cup seat adsorbs the flexible circuit board and drives the flexible circuit board to be placed in the tray.

[0018] Preferably, multiple sets of the auxiliary conveying mechanism, the second limiting mechanism, the tray, the fourth driving component, the third lifting component, and the suction cup seat are provided, and multiple sets of the auxiliary conveying mechanism, the second limiting mechanism, the tray, the fourth driving component, the third lifting component, and the suction cup seat are respectively located on both sides of the main conveying mechanism.

[0019] By adopting the above technical solution, multiple sets of suction cups can jointly grasp the flexible circuit board and place it in multiple trays, thereby greatly improving the efficiency of picking up and placing the flexible circuit board.

[0020] Preferably, an adhesive layer is provided on the base plate, and the substrate is bonded to the adhesive layer.

[0021] By adopting the above technical solution, when the lifting mechanism lifts the flexible circuit board, the adhesive layer can bond and fix the substrate, so that the substrate will not lift up.

[0022] Preferably, a screw is rotatably disposed inside the base plate, and a slide plate is slidably disposed inside the base plate. The screw is threaded through the slide plate, and multiple push blocks are disposed on the side wall of the slide plate. Multiple sliding grooves are formed on the base plate, and a top block is slidably disposed inside the sliding grooves of the base plate. The top block is located below the edge of the adhesive layer and is slidably disposed on the slide plate. A push groove is inclinedly formed inside the top block, and the push block is slidably disposed inside the push groove.

[0023] By adopting the above technical solution, the adhesive layer needs to be removed and replaced after a long period of use. Rotating the screw causes the slide plate to slide, and the slide plate causes the pusher block to move in the push groove. During the movement of the pusher block, the top block moves upward in the slide groove. The top of the top block extends out of the slide groove and abuts against the edge of the adhesive layer, thereby lifting the edge of the adhesive layer, making it easier for the operator to remove the adhesive layer.

[0024] Preferably, a plurality of rotating wheels are spaced apart on the side of the top wall of the top block near the adhesive layer, the height of the top of the rotating wheels is greater than the height of the top wall of the top block, and the rotating wheels move upward to abut against the adhesive layer.

[0025] By adopting the above technical solution, when the top block moves upward, it drives the rotating wheel to rise synchronously. The rotating wheel first contacts the bottom wall of the adhesive layer, so that the adhesive layer does not contact the top wall of the top block, thus preventing the adhesive layer from sticking to the top block. As the top block continues to rise, the rotating wheel rolls on the bottom wall of the adhesive layer, which makes it easier to lift the edge of the adhesive layer.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. When quickly changing flexible circuit boards, the substrate is first installed on the base plate, and then the base plate is sent into the main conveying mechanism. The empty tray is sent into the auxiliary conveying mechanism. The first limiting mechanism fixes the base plate on the main conveying mechanism, and the second limiting mechanism fixes the tray on the auxiliary conveying mechanism. The lifting mechanism lifts the flexible circuit board, and the gripping mechanism then grips the lifted flexible circuit board and places it in the tray. Subsequently, the first and second limiting mechanisms drive the base plate and the tray to move, and the gripping mechanism picks up and places the flexible circuit board again. The gripping and placing of the flexible circuit board are all automated operations, which greatly improves the efficiency and yield of flexible circuit board picking and placing.

[0028] 2. After the main conveying mechanism moves the base plate to the designated position, the two first lifting components move the top plate upward. The top plate pushes the base plate upward to disengage from the main conveying mechanism. The top plate and the first baffle clamp the base plate vertically, and the positioning pin is inserted into the positioning hole and fixed the base plate horizontally. This makes the gripping mechanism grip the flexible circuit board more accurately. At the same time, the first driving component moves the base plate through the moving seat, which facilitates the gripping of subsequent flexible circuit boards.

[0029] 3. After the main conveying mechanism moves the pallet to the designated position, the second lifting component moves the pallet upward. The pallet pushes the pallet upward to disengage from the auxiliary conveying mechanism. The pallet and the second baffle clamp the pallet vertically. The two first translation components move the two clamping plates horizontally to clamp the pallet, making the gripping mechanism more accurate when placing the flexible circuit board. At the same time, the second driving component moves the pallet through the translation plate, which facilitates the subsequent placement of the flexible circuit board. Attached Figure Description

[0044] The following is in conjunction with the appendix Figures 1-13 This application will be described in further detail.

[0045] This application discloses an FPC quick-change depaneling machine.

[0046] Example 1:

[0047] Reference Figure 1 and Figure 2 An FPC quick-change depaneling machine includes a chassis 1, with a feed inlet 33 on one side and a discharge outlet 34 on the other side.

[0048] Reference Figure 3 A main conveyor mechanism 4 is installed in the middle of the chassis 1. A base plate 2 is movably placed on the main conveyor mechanism 4, and a base plate 10 is adhered to the base plate 2. A secondary conveyor mechanism 7 is installed on both sides of the main conveyor mechanism 4 inside the chassis 1, and a tray 3 is movably placed on the secondary conveyor mechanism 7.

[0049] Two second limiting mechanisms 8 are installed inside the chassis 1. The two second limiting mechanisms 8 are located below the two auxiliary conveying mechanisms 7. The second limiting mechanisms 8 can fix the pallet 3 and drive the pallet 3 to move when it is fixed.

[0050] Reference Figure 3 and Figure 4The first limiting mechanism 5 is installed inside the chassis 1. The first limiting mechanism 5 is located below the main conveying mechanism 4. The first limiting mechanism 5 can fix the base plate 2 and drive the base plate 2 to move when it is fixed.

[0051] A lifting mechanism 6 is installed on the first limiting mechanism 5, which can lift the flexible circuit board inside the substrate 10. A gripping mechanism 9 is installed inside the chassis 1 above the main conveying mechanism 4 and the auxiliary conveying mechanism 7. The gripping mechanism 9 can grip the flexible circuit board lifted by the lifting mechanism 6 and place it on the tray 3.

[0052] The automated pick-and-place process used for quick-change of flexible printed circuit boards (FPCs) is as follows:

[0053] First, the substrate 10 carrying the flexible circuit board is mounted on the base plate 2, and the base plate 2 is fed into the main conveying mechanism 4 through the feed port 33; simultaneously, the empty tray 3 is fed into the auxiliary conveying mechanism 7 through the feed port 33. After the main conveying mechanism 4 conveys the base plate 2 to the designated position, the main limiting mechanism precisely locks the base plate 2 onto the main conveying mechanism 4; after the auxiliary conveying mechanism 7 conveys the tray 3 to the designated position, the auxiliary limiting mechanism securely fixes the tray 3 onto the auxiliary conveying mechanism 7.

[0054] After positioning, the lifting mechanism 6 smoothly lifts multiple flexible circuit boards from below the base plate 2, separating them from the substrate 10. The gripping mechanism 9 then picks up the lifted flexible circuit boards and transfers them precisely into the tray 3 on the auxiliary conveying mechanism 7. After a single pick-and-place operation, the main limiting mechanism and the auxiliary limiting mechanism drive the base plate 2 and the tray 3 to move stepwise, bringing the next workstation to the operating position, allowing the gripping mechanism 9 to continue the subsequent pick-and-place cycle. Once all the flexible circuit boards on the base plate 2 have been gripped, the base plate 2 and the tray 3 are discharged from the discharge port 34 on the other side of the chassis 1, and then new base plates 2 and trays 3 are fed in.

[0055] The FPC quick-change depaneling machine realizes fully automated operation from substrate 10 separation to tray 3 placement, replacing the traditional manual handling method, significantly improving the efficiency, positioning accuracy and operation consistency of flexible circuit board transfer, thereby effectively improving production yield and equipment utilization.

[0056] Reference Figure 4Specifically, the main conveying mechanism 4 includes two main supports 41, a main conveyor belt 42, and a main drive unit 43. The two main supports 41 are fixedly installed at intervals inside the housing 1. The two main conveyor belts 42 are rotatably mounted on the side walls of the two main supports 41 that are close to each other via rollers. The two main drive units 43 are fixedly installed on the side walls of the two main supports 41 that are far from each other. In this application, the main drive unit 43 can be a servo motor, and the drive ends of the two main drive units 43 are connected to the rollers inside the main conveyor belts 42. The base plate 2 is placed on the main conveyor belts 42, and the main drive units 43 drive the main conveyor belts 42 to rotate, which in turn drives the base plate 2 to move.

[0057] Reference Figure 5 The first limiting mechanism 5 includes a first driving component 51, a movable seat 52, two first baffles 53, a first lifting component 54, and a top plate 55. The first driving component 51 is installed inside the housing 1, and the movable seat 52 is slidably installed inside the housing 1 along the moving direction of the bottom plate 2. In this application, the first driving component 51 can be selected as a linear module, and the movable seat 52 is fixedly connected to the translation end of the first driving component 51.

[0058] Reference Figure 5 and Figure 6 Both first baffles 53 are fixedly installed at both ends of the movable base 52 via first brackets 14, and the two first baffles 53 are located above the two main brackets 41. One positioning pin 11 is fixedly installed on the bottom wall of one first baffle 53, and two positioning pins 11 are fixedly installed on the bottom wall of the other first baffle 53. Three positioning holes 12 are opened on both sides of the base plate 2.

[0059] Two first lifting components 54 are fixedly installed at both ends of the movable base 52, and two top plates 55 are fixedly installed at the lifting ends of the two first lifting components 54. In this application, the first lifting component 54 can be a cylinder, and the top plate 55 is located below the main support 41. Both ends of the movable base 52 along the moving direction of the base plate 2 are equipped with blocking blocks 16 that are slidably installed in the vertical direction by cylinders.

[0060] When the main conveying mechanism 4 moves the base plate 2, the blocking block 16 moves upward. When the base plate 2 abuts against the blocking block 16, the base plate 2 is in position. The two first lifting members 54 move the top plate 55 upward, and the two top plates 55 lift the base plate 2 off the main conveyor belt. The two top plates 55 and the two first baffles 53 clamp and fix the base plate 2 vertically, and the three positioning pins 11 are inserted into the three positioning holes 12 of the base plate 2, which can limit the base plate 2 horizontally, thus forming a stable fixation for the base plate 2. Then the blocking block 16 descends and resets. When the first driving member 51 moves the moving seat 52, the moving seat 52 can move the base plate 2, which facilitates the gripping mechanism 9 to continue to perform the subsequent pick-and-place cycle.

[0061] Reference Figure 7 The auxiliary conveying mechanism 7 includes two auxiliary supports 71, an auxiliary conveyor belt 72, and auxiliary drive components 73. The two auxiliary supports 71 are fixedly installed at intervals inside the housing 1. The two auxiliary conveyor belts 72 are rotatably mounted on the side walls of the two auxiliary supports 71 that are close to each other via rollers. The two auxiliary drive components 73 are fixedly installed on the side walls of the two auxiliary supports 71 that are far from each other. In this application, the auxiliary drive components 73 can be selected as servo motors, and the drive ends of the two auxiliary drive components 73 are connected to the rollers inside the auxiliary conveyor belts 72. The tray 3 is placed on the auxiliary conveyor belts 72, and the auxiliary drive components 73 drive the auxiliary conveyor belts 72 to rotate, thereby moving the tray 3.

[0062] Reference Figure 7 and Figure 8 The second limiting mechanism 8 includes a second driving component 81, a translation plate 82, a second lifting component 83, a support plate 84, two second baffles 85, a first translation component 86, and a clamping plate 87. The second driving component 81 is installed inside the housing 1, and the translation plate 82 is fixedly installed on the translation end of the second driving component 81. In this application, the second driving component 81 can be selected as a linear module. A blocking plate 17 is slidably installed vertically at the end of the translation plate 82 along the moving direction of the tray 3 via a cylinder.

[0063] The second lifting component 83 is fixedly installed in the middle of the top wall of the translation plate 82. The support plate 84 is lifted and lowered on the translation plate 82 via four telescopic rods 18, and the support plate 84 is located below the tray 3. In this application, the second lifting component 83 can be a cylinder, and the lifting end of the second lifting component 83 is fixedly connected to the middle of the bottom wall of the support plate 84. Two second baffles 85 are fixedly installed on both sides of the translation plate 82 via two second brackets 15, and the two second baffles 85 are located above the two auxiliary brackets 71.

[0064] Two first translation components 86 are fixedly installed on both sides of the bottom wall of the pallet 84 along the moving direction of the pallet 3. Two clamping plates 87 are installed on the translation ends of the two first translation components 86. In this application, the first translation components 86 can be cylinders. Two positioning blocks 19 are fixedly installed on the top walls of the two clamping plates 87, and two positioning grooves 20 are formed on the opposite side walls of the pallet 3.

[0065] When the secondary conveyor mechanism 7 moves the pallet 3, the baffle plate 17 rises and moves. When the pallet 3 abuts against the baffle plate 17, the pallet 3 is in position. The second lifting member 83 moves the pallet 84 upward, lifting the pallet 3 off the secondary conveyor belt. The pallet 84 and the two second baffle plates 85 clamp and fix the pallet 3 vertically. The two first translation members 86 move the positioning block 19 through the clamping plate 87 and insert it into the positioning groove 20 of the pallet 3, thus limiting the pallet 3 horizontally and fixing it securely. Then the baffle plate 17 descends and resets. When the second driving member 81 moves the translation plate 82, the translation plate 82 moves the pallet 3, making it easier for the gripping mechanism 9 to continue the subsequent pick-and-place cycle.

[0066] Reference Figure 5 and Figure 6 The lifting mechanism 6 comprises a three-axis moving assembly 61 and two lifting heads 62. The three-axis moving assembly 61 is mounted on a sliding base, and the two lifting heads 62 are magnetically attached to the lifting end of the three-axis moving assembly 61. In this application, the horizontal movement of the three-axis moving assembly 61 is controlled by two linear modules, and the vertical movement is controlled by a motor and a cam. The base plate 2 has multiple insertion holes 23, each corresponding to a flexible circuit board. The three-axis moving assembly 61 moves the lifting heads 62 to insert them into the insertion holes 23 of the base plate 2, thereby lifting the flexible circuit boards within the substrate 10.

[0067] Reference Figure 3 and Figure 9 The gripping mechanism 9 includes a gantry frame 91, a third drive component 92, two fourth drive components 93, a third lifting component 94, a suction cup base 95, and multiple elastic components 96. The gantry frame 91 is fixedly installed inside the housing 1 and located above the main conveying mechanism 4 and the two auxiliary conveying mechanisms 7. The third drive component 92 is fixedly installed horizontally on the gantry frame 91, the two fourth drive components 93 are fixedly installed on the translation ends of the third drive component 92, and the two third lifting components 94 are fixedly installed on the lifting ends of the two fourth drive components 93. In this application, the third drive component 92 and the fourth drive component 93 can be selected as linear modules, and the third lifting component 94 can be selected as a cylinder.

[0068] The lifting end of the third lifting component 94 is fixedly mounted with a connecting plate 21. The suction cup seat 95 is slidably mounted on the bottom of the connecting plate 21 via four guide rods. Every four elastic elements 96 are installed between the connecting plate 21 and the suction cup seat 95. In this application, the elastic elements 96 can be selected as springs. Multiple sets of suction nozzles 22 are installed on the bottom of the suction cup seat 95, and the air passage distance of the multiple sets of suction nozzles 22 is independently set.

[0069] The third driving member 92 and the fourth driving member 93 work together to control the movement of the third lifting member 94, thereby driving the suction cup seat 95 to move in the horizontal and vertical directions. When the suction cup seat 95 moves to a preset position above the substrate 10, the third lifting member 94 drives it to move downward until the suction nozzle 22 at the bottom of the suction cup seat 95 contacts the surface of the flexible circuit board.

[0070] At this time, the bottom lifting mechanism 6 is activated, lifting the flexible circuit board inside the substrate 10 upwards. During the ascent, the flexible circuit board pushes the suction cup seat 95 upwards simultaneously, forcing the elastic element 96 to compress and deform, thereby forming a flexible, pressing contact between the suction nozzle 22 and the flexible circuit board. After ensuring stable attachment of the circuit board, the suction nozzle 22 is connected to negative pressure, reliably adsorbing the flexible circuit board. Subsequently, the third drive element 92 and the fourth drive element 93 lift, transfer, and precisely release it into the designated position within the tray 3.

[0071] Reference Figure 6 Nine adhesive layers 13 are pasted on the base plate 2, and the nine adhesive layers 13 are 3 3. Arrangement. Nine substrates 10 are bonded to nine adhesive layers 13, and holes corresponding to the insertion holes 23 are formed on the adhesive layers 13. Multiple positioning posts 32 are fixedly installed on the base plate 2, and every four positioning posts 32 are inserted into an adhesive layer 13 and a substrate 10 respectively to position them. When the lifting mechanism 6 lifts the flexible circuit board, the adhesive layer 13 at the bottom of the substrate 10 can provide sufficient adhesion to effectively constrain the substrate 10 and prevent it from warping or displacing under local lifting stress.

[0072] The four corners of the substrate 10 are all right angles, while the four corners of the adhesive layer 13 are all rounded. The right angles of the substrate 10 are not bonded to the adhesive layer 13, and the adhesive force between the adhesive layer 13 and the base plate 2 is greater than the adhesive force between the adhesive layer 13 and the substrate 10. After the flexible circuit board on the substrate 10 has been removed and placed, the substrate 10 can be quickly peeled off from the adhesive layer 13 through the right angles of the substrate 10 corners, thus facilitating the bonding of a new substrate 10.

[0073] The implementation principle of an FPC quick-change depaneling machine according to an embodiment of this application is as follows: First, a substrate 10 carrying flexible circuit boards is installed on a base plate 2, and the base plate 2 is sent into the main conveying mechanism 4; simultaneously, an empty tray 3 is sent into the auxiliary conveying mechanism 7. After the main conveying mechanism 4 conveys the base plate 2 to the designated position, the main limiting mechanism precisely locks the base plate 2 onto the main conveying mechanism 4; after the auxiliary conveying mechanism 7 conveys the tray 3 to the designated position, the auxiliary limiting mechanism securely fixes the tray 3 onto the auxiliary conveying mechanism 7. After positioning, the lifting mechanism 6 smoothly lifts multiple flexible circuit boards from below the base plate 2, separating them from the substrate 10. The gripping mechanism 9 then adsorbs the lifted flexible circuit boards and transfers and precisely places them into the tray 3 on the auxiliary conveying mechanism 7. After a single pick-and-place operation is completed, the main limiting mechanism and the auxiliary limiting mechanism respectively drive the base plate 2 and the tray 3 to move stepwise, so that the next workstation reaches the working position, and the gripping mechanism 9 can continue to perform subsequent pick-and-place cycles. Once all the flexible circuit boards on the base plate 2 have been picked up, the base plate 2 and tray 3 are sent out from the other side of the chassis 1, and then new base plates 2 and trays 3 are sent in. The FPC quick-change depaneling machine realizes fully automated operation from the separation of the substrate 10 to the placement of the tray 3, replacing the traditional manual picking and placing method, significantly improving the efficiency, positioning accuracy and operational consistency of flexible circuit board transfer, thereby effectively improving the production yield and equipment utilization rate.

[0074] Example 2:

[0075] Reference Figure 10 , Figure 11 , Figure 12 and Figure 13 The difference between this embodiment and Embodiment 1 is that two screws 25 are rotatably installed inside the base plate 2, each screw 25 is located between two adhesive layers 13, and a knob 24 is fixedly installed at the end of the screw 25 outside the base plate 2. Six slide plates 26 are slidably installed inside the base plate 2 along its own conveying direction, and each screw 25 is threaded through three slide plates 26 respectively.

[0076] The top wall of the base plate 2 has six grooves 28 along its thickness direction. Three grooves 28 are arranged at intervals along the length of a screw 25. Each groove 28 is located at the bottom of two adjacent adhesive layers 13 near their edges. A top block 29 is slidably installed in each groove 28 along the thickness direction of the base plate 2. The opposite sides of the top wall of the top block 29 are rounded. Three rotating wheels 31 are installed at intervals on the rounded corners of the top block 29. The height of the top wall of the top block 29 is lower than the height of the top of the rotating wheels 31.

[0077] An opening is formed in the middle of the bottom wall of the top block 29, through which the top block 29 is slidably mounted on the slide plate 26. Push grooves 30 are formed on both inner side walls of the top block 29, and the push grooves 30 are inclined. Push blocks 27 are fixedly mounted on the opposite side walls of each slide plate 26, and two push blocks 27 symmetrically mounted on both sides of the slide plate 26 are slidably mounted in the two push grooves 30 within a top block 29.

[0078] The implementation principle of Embodiment 2 of this application is as follows: When the adhesive layer 13 needs to be removed and replaced after long-term use, the adhesion between the adhesive layer 13 and the base plate 2 is relatively strong, making it difficult for the operator to peel off the adhesive layer 13. At this time, the knob 24 can be rotated. The knob 24 drives the slide plate 26 to slide through the screw 25. The slide plate 26 then drives multiple push blocks 27 to move synchronously. During the movement of the push blocks 27, the top block 29 is driven to move upward through the push groove 30. The top block 29 drives the rotating wheel 31 to move upward. The rotating wheel 31 will contact the bottom of the adhesive layer 13 before the top block 29, avoiding direct adhesion between the adhesive layer 13 and the surface of the top block 29. As the top block 29 continues to rise, the rotating wheel 31 rolls under the adhesive layer 13, thereby smoothly lifting the edge of the adhesive layer 13, making it easy for the operator to peel off the old adhesive layer 13.
