Description

Technical Field

[0001] This invention belongs to the technical field of auxiliary equipment for manufacturing plate-shaped electronic components, and specifically relates to a vertical plate edge degumming machine. Background Technology

[0002] In the manufacturing process of sheet-like electronic components such as PCBs or IC substrates, edge debonding is a crucial step in ensuring the cleanliness of the molding area. During the full-board resin via plugging process of PCBs and IC substrates, to prevent resin contamination of process holes or mounting holes on the board edges, protective tape needs to be applied to the four edges of the board before plugging, and then removed after plugging. For a long time, this process has relied mainly on manual labor, where operators hold the PCB or IC substrate and manually peel off the protective tape edge by edge. This is not only labor-intensive and inefficient, but also prone to contaminating the molding area of ​​the PCB or IC substrate with residual ink from the tape, causing irreversible quality defects.

[0003] To overcome the numerous drawbacks of manual adhesive removal, Chinese patent document CN120751611B discloses a vertical automated PCB edge adhesive removal machine. This machine addresses the adhesive removal needs of the four edges of a PCB by incorporating four independent actuators: a left adhesive removal device, a right adhesive removal device, an upper adhesive removal device, and a lower adhesive removal device. Each actuator independently removes the adhesive tape from its corresponding edge. It is also equipped with upper clamping components, lower clamping components, left clamping components, and right clamping components to hold the corresponding sides of the PCB. The removed adhesive tape waste is collected in a receiving trolley below via a conveyor channel, eliminating the need for manual cleaning. This vertical automated PCB edge adhesive removal machine automates the PCB edge adhesive removal process, reduces the labor intensity of operators, minimizes the risk of contamination from manual contact with the PCB surface, and improves production efficiency and product yield to a certain extent.

[0004] However, the four independent adhesive-removing mechanisms in the aforementioned vertical automated PCB edge peeling machine each require their own independent drive and transmission structures, resulting in a large number of parts, which increases the manufacturing cost of the equipment and also raises the difficulty and cost of subsequent maintenance. Furthermore, the aforementioned vertical automated PCB edge peeling machine uses a unidirectional pulling method for adhesive removal. During the peeling process, the tape is only subjected to tension in one direction, leading to uneven force distribution. Excessive tension near the peeling jaws can easily cause the tape to break, while insufficient tension further away from the jaws can easily result in tape residue. The unidirectional pulling force can also be concentrated in localized areas of the PCB board. When the PCB board is thin or made of brittle material, it is prone to deformation or even breakage. Summary of the Invention

[0005] The purpose of this invention is to propose a vertical board edge degumming machine to solve the technical problem of complex structure in existing degumming equipment.

[0006] To solve the above problems, the present invention provides a technical solution for a vertical board edge degumming machine: A vertical board edge degumming machine includes a frame, a rotary drive mechanism, a clamping plate assembly, and a degumming assembly; The clamping plate assembly is assembled at the output end of the rotary drive mechanism and is used to clamp the corresponding side of the adhesive sheet to be peeled. The rotary drive mechanism is used to drive the clamping plate assembly to rotate. The rotary drive mechanism and the adhesive tearing assembly are arranged sequentially along a straight line, and at least one of the rotary drive mechanism and the adhesive tearing assembly is slidably mounted on the frame along the straight line. When the clamping plate assembly and the adhesive-removing assembly approach each other to a set position, the adhesive-removing assembly removes the adhesive tape from the corresponding side of the sheet material to be peeled; after the clamping plate assembly and the adhesive-removing assembly move away from each other, the rotation drive mechanism drives the clamping plate assembly to rotate so that the different sides of the sheet material to be peeled correspond to the adhesive-removing assembly respectively.

[0007] Beneficial Effects: This invention uses a rotary drive mechanism to rotate the clamping plate assembly in a vertical plane, sequentially rotating the four corresponding sides of the board to be peeled to their corresponding positions with the peeling assembly. By bringing the clamping plate assembly and the peeling assembly closer together, the adhesive tape on the board is delivered to the peeling assembly for removal. The entire system requires only one peeling assembly to remove the adhesive tape from all four sides of the board, eliminating the need for separate peeling mechanisms on each side. This reduces the number of parts in the vertical board edge de-adhesive machine, lowering manufacturing costs and reducing maintenance difficulty and costs. Furthermore, this invention automates the process, eliminating operator hand contact with the board surface, effectively reducing the risk of contamination and improving product yield.

[0008] Furthermore, the adhesive tearing assembly includes two sets of adhesive tearing claw pairs capable of moving synchronously towards or away from each other, each pair of adhesive tearing claws comprising two oppositely arranged adhesive tearing grippers.

[0009] Beneficial effects: The adhesive tearing assembly uses two sets of tearing claws that can move synchronously in opposite directions or in opposite directions. During the tearing process, the adhesive tape is subjected to force from both sides of the board at the same time, making the force on the adhesive tape more even and avoiding the problem of adhesive tape breakage or residue caused by pulling in one direction.

[0010] Furthermore, the distance between the two tearing claws in the tearing claw pair is adjustable. One of the two tearing claws is provided with a toothed biting part, and the other is provided with a biting groove that matches the toothed biting part. The tearing claw pair clamps the tape by the biting engagement of the toothed biting part and the biting groove.

[0011] Beneficial effects: The meshing of the toothed jaws and the jaw grooves increases the friction and biting force between the tearing jaws and the tape, improves the reliable gripping effect of the tearing jaws on the tape, prevents the tape from slipping out of the gap between the two tearing jaws during the tearing process, improves the reliability of the tearing operation, and reduces the occurrence of tearing failures.

[0012] Furthermore, each of the two adhesive-tearing claws is embedded with a detection probe. When the adhesive-tearing claws are closed and there is no adhesive tape between the two adhesive-tearing claws, the two detection probes form a conductive circuit.

[0013] Beneficial effects: When the tearing claws are closed and there is no tape between the two tearing claws, the two detection probes form a conductive circuit. If there is tape, the two detection probes are blocked by the tape and cannot conduct, thus determining whether the tearing claws have successfully gripped the tape. This detection method can promptly detect cases where tape has not been gripped, avoiding invalid tearing actions and improving the success rate of tape tearing operations. The detection process can be completed before the tearing action begins, ensuring the smooth progress of subsequent processes and reducing rework problems caused by missed tape removal.

[0014] Furthermore, the adhesive tearing assembly also includes a rotary de-adhesion mechanism corresponding to the adhesive tearing claw pair. The output end of the rotary de-adhesion mechanism is fixed relative to the adhesive tearing claw pair to drive the adhesive tearing claw pair to rotate. A tape collection device is provided on the frame below the adhesive tearing assembly.

[0015] Beneficial effects: After the tape is torn off, the rotating de-tapping mechanism drives the tearing claws to flip over, automatically putting the tape into the tape collection device below. This achieves automatic collection of tape waste, eliminating the need for manual cleaning of the tape on the claws, simplifying the work process and reducing the labor intensity of the operators.

[0016] Furthermore, a tearing limit block is provided between the two tearing claws. The tearing limit block moves horizontally together with the tearing claws to flatten any sagging tape.

[0017] Beneficial effects: The tape-tearing limit block can flatten any sagging tape before the tape-tearing jaws grip it, ensuring that the tape can enter smoothly between the two tape-tearing jaws. This avoids problems such as clamping failure or incomplete tape tearing caused by tape sagging, improves the accuracy of tape clamping, and further guarantees the tape-tearing effect.

[0018] Furthermore, the clamping assembly includes a mounting base plate and two sets of clamping units movably mounted on the mounting base plate in the vertical direction. The mounting base plate is connected to the output end of the rotary drive mechanism. Each clamping unit includes two sets of clamping components arranged at intervals in the horizontal direction. Each clamping component has two independent clamping ends that can rotate and extend, and two abutment ends that correspond to and cooperate with the clamping ends and can extend. The extension and retraction directions of the abutment ends and the corresponding clamping ends are the same, and a clamping channel is formed between them. The two clamping ends and the two abutment ends are respectively used to clamp the two mutually perpendicular sides of the adhesive sheet to be peeled.

[0019] Beneficial effects: The clamping assembly has a high degree of integration and a compact structure, which can adapt to the adhesive-bearing materials of different heights and sizes. The two clamping ends of each clamping component can operate independently. That is, if the top and bottom edges of the adhesive-bearing material are to be peeled, only the left and right clamping ends of the material can be clamped to achieve the purpose of clamping the material. If the left and right edges of the material are to be peeled, only the top clamping end of the material can be clamped to achieve the purpose of clamping the material. There is no need to set clamping components on all four sides of the material to be peeled, which simplifies the structure of the clamping assembly.

[0020] Furthermore, the clamping plate assembly also includes a first synchronous transmission mechanism disposed on the mounting base plate. The first synchronous transmission mechanism is in transmission cooperation with the two sets of clamping units to drive the two sets of clamping units to move synchronously towards or away from each other in the vertical direction.

[0021] Beneficial effects: The two sets of clamping units share a first synchronous transmission mechanism to achieve synchronous action, so that the plate is evenly clamped in the vertical direction. There is no need to configure a separate drive structure and transmission structure for each set of clamping units, which simplifies the structure of the clamping plate assembly; at the same time, it simplifies the control logic of the equipment.

[0022] Furthermore, each clamping unit includes a mounting base, on which a second synchronous transmission mechanism is provided. The second synchronous transmission mechanism is in transmission cooperation with the two clamping components to drive the two clamping components to move synchronously towards or away from each other in the horizontal direction.

[0023] Beneficial effects: The two sets of clamping components in each clamping unit share a second synchronous transmission mechanism to achieve consistent movement in the horizontal direction, so that the plate is clamped evenly in the horizontal direction, which further improves the stability of plate clamping. There is no need to configure a separate horizontal drive structure and transmission structure for each set of clamping components, which simplifies the structure of the clamping components; it also simplifies the control logic of the equipment and enables the equipment to adapt to plates of different widths.

[0024] Furthermore, each of the two clamping components of one set of clamping units includes a limiting member that can extend and retract in the horizontal direction. The two limiting members are used to stop and cooperate with the first side of the adhesive sheet to be peeled to limit the placement height of the adhesive sheet to be peeled. One of the two abutting ends has a limiting surface for stopping and cooperating with the second side of the adhesive sheet to be peeled, and the first side is perpendicular to the second side.

[0025] Beneficial effects: The two limiting components play a positioning role during the placement of the board, avoiding problems such as inaccurate glue removal position or unstable clamping caused by the board's skewed position; the limiting components are telescopic and can be retracted after positioning is completed, without affecting subsequent glue removal and flipping actions.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] An embodiment of the vertical board edge degumming machine provided by the present invention: like Figure 1 As shown, the vertical board edge degumming machine adopts a vertical layout and includes a frame 1, a rotating lifting module 2, a clamping plate assembly 3, a degumming assembly 4, and a tape collection device 7.

[0030] like Figure 2 As shown, the frame 1 serves as the supporting foundation for the entire machine; the rotary lifting module 2 is used to drive the clamping plate assembly 3 to rotate around the horizontal axis in the vertical plane and to lift in the vertical direction; the clamping plate assembly 3 is used to clamp the adhesive sheet to be peeled; the adhesive peeling assembly 4 is used to peel off the adhesive tape on the adhesive sheet to be peeled; and the adhesive tape collecting device 7 is used to collect the peeled adhesive tape 6.

[0031] This embodiment uses PCB board 5 as the substrate to be peeled off.

[0032] Specifically, such as Figure 3 and Figure 4 As shown, the rotary lifting module 2 includes a lifting drive mechanism 21 and a rotary drive mechanism 22. The lifting drive mechanism 21 includes a mounting bracket 211, a slide module 212, and a lifting drive source 213. The mounting bracket 211 is fixed on the frame 1. Two sets of slide modules 212 are arranged parallel to each other in the left-right direction. The two sets of slide modules 212 are arranged vertically and are both mounted on the mounting bracket 211. The lifting drive source 213 includes a reducer and a steering mechanism 215 that are connected by transmission. The steering mechanism 215 has two output ends, left and right. The two output ends are connected to the power input ends of the two slide modules 212 by a gear steering box, so that the slides on the two sets of slide modules 212 can perform synchronous lifting and lowering movements through a single lifting drive source 213.

[0033] The rotary drive mechanism 22 includes a motor base plate 221 and a rotary drive source 222. The motor base plate 221 extends in the left-right direction, and its left and right ends are respectively connected to the slides of two slide modules 212, thereby being driven by the slide modules 212 to lift and lower. The rotary drive source 222 is mounted on the motor base plate 221 and includes a reducer and a rotary servo motor with transmission connection. The rotation shaft of the rotary servo motor serves as the power output end of the rotary drive mechanism 22 and is connected to the entire clamping plate assembly 3, thereby driving the entire clamping plate assembly 3, that is, driving the PCB board 5 to rotate 360° around the horizontal axis in the vertical plane. The rotation angle is controlled by the encoder feedback of the rotary servo motor and the controller of the entire vertical board edge degumming machine to ensure accurate positioning for each board edge switching.

[0034] like Figure 5 As shown, the clamping assembly 3 includes a mounting base plate 31 and two sets of clamping units 32 arranged vertically at intervals. The two sets of clamping units 32 are movably assembled with the mounting base plate 31 in the vertical direction, thereby adjusting the clamping height of the two sets of clamping units 32 to accommodate PCB boards 5 of different heights. Specifically, as... Figure 5 and Figure 6As shown, a first synchronous transmission mechanism 33 is mounted on the mounting base 31. The first synchronous transmission mechanism 33 is a synchronous belt mechanism, including a first motor 331, a first driving pulley 332, a first driven pulley 333, and a first synchronous belt 334. The first motor 331 is fixed on the mounting base 31, and its output shaft is coaxially connected to the first driving pulley 332. The first driven pulley 333 is rotatably assembled with the mounting base 31 and is arranged vertically spaced from the first driving pulley 332. The first synchronous belt 334 is wound around the first driving pulley 332 and the first driven pulley 333. First slide rails 311 extending vertically are fixed on the left and right sides of the first synchronous transmission mechanism 33 on the mounting base 31. Two sets of first sliders 312 arranged vertically spaced are slidably mounted on each first slide rail 311.

[0035] In this embodiment, each clamping unit 32 includes a mounting base 321 and two sets of horizontally spaced clamping assemblies 326 mounted on the mounting base 321. First slider support blocks 313 are connected to the left and right ends of the mounting base 321 at positions corresponding to the first slider 312, and the first slider support blocks 313 are connected to the corresponding positions of the first slider 312. A first synchronous belt pressure block is installed on the mounting base 321 at the position corresponding to the first synchronous belt 334. In the two sets of clamping units 32, the first synchronous belt pressure block on one mounting base 321 presses against the left side of the first synchronous belt 334, and the first synchronous belt pressure block on the other mounting base 321 presses against the right side of the first synchronous belt 334. When the first motor 331 rotates forward or reverse, the two mounting bases 321 can achieve synchronous movement towards or away from each other.

[0036] The two sets of clamping components 326 assembled on the same mounting base 321 have the same structure. The structure of one set of clamping components 326 will be described below.

[0037] like Figure 6 , Figure 7 and Figure 8As shown, the clamping assembly 326 includes a cylinder fixing plate 3261, a first slide cylinder 3262, a second slide cylinder 3263, a first rotary clamping cylinder 3265, and a second rotary clamping cylinder 3266. The cylinder fixing plate 3261 has two mutually perpendicular mounting surfaces. The first slide cylinder 3262 is fixed on the horizontal mounting surface, and the second slide cylinder 3263 is fixed on the vertical mounting surface. The first rotary clamping cylinder 3265 is mounted on the slide of the first slide cylinder 3262 and is driven to move back and forth by the first slide cylinder 3262. The second rotary clamping cylinder 3266 is mounted on the slide of the second slide cylinder 3263 and is driven to move back and forth by the second slide cylinder 3263. A first abutment block 3269 is fixed to the cylinder body of the first rotary clamping cylinder 3265. A first clamping block 3267 is connected to the piston rod of the first rotary clamping cylinder 3265, which can drive the first clamping block 3267 to rotate 90° and extend and retract back and forth. The first clamping block 3267 has a limiting groove for the PCB board 5 to extend into, and the first abutment block 3269 is used to abut against the surface of the PCB board 5. The first clamping block 3267 and the first abutment block 3269 cooperate to clamp the upper or lower edge of the PCB board 5. A second abutment block 3270 is fixed to the cylinder body of the second rotary clamping cylinder 3266. A second clamping block 3268 is connected to the piston rod of the second rotary clamping cylinder 3266, which can drive the second clamping block 3268 to rotate 90° and extend and retract back and forth. The structure of the second clamping block 3268 is the same as that of the first clamping block 3267. The second abutting block 3270 has a limiting step, which has a limiting surface and an abutting surface. The limiting surface is used to stop the left or right side of the PCB board 5. The first clamping block 3267 cooperates with the first abutting block 3269 to form a clamping channel, which can clamp the top or bottom edge of the PCB board 5. The second clamping block 3268 cooperates with the second abutting block 3270 to form a clamping channel, which can clamp the left or right side of the PCB board 5. The first clamping block 3267 and the second clamping block 3268 work independently. When clamping the PCB board 5, only one of them works while the other is disengaged. The first clamping block 3267 and the second clamping block 3268 respectively form the two clamping ends of the entire clamping assembly 326; the first abutting block 3269 and the second abutting block 3270 respectively form the two abutting ends of the entire clamping assembly 326.

[0038] It should be noted that both the first clamping block 3267 and the second clamping block 3268 are operated by corresponding rotary clamping cylinders. First, the first clamping block 3267 and the second clamping block 3268 are rotated 90°, then retracted backward to engage with the corresponding first abutment block 3269 and the second abutment block 3270, thereby clamping the PCB board 5. The process of releasing the PCB board 5 is the reverse of the clamping process described above, and will not be elaborated further here.

[0039] like Figure 6and Figure 7 As shown, to facilitate the positioning of the PCB board 5, a third slide cylinder 3264 is respectively provided in the two sets of clamping components 326 of one of the clamping units 32. A limiter 3271 is fixed on the slide of the third slide cylinder 3264, and the third slide cylinder 3264 is fixed on the cylinder body of the second rotary clamping cylinder 3266. The two limiters 3271 are used to stop the upper edge of the PCB board 5 to limit the placement height of the PCB board 5. The limiters 3271 cooperate with the second clamping block 3268 to quickly position the PCB board 5.

[0040] like Figure 5 and Figure 9 As shown, the mounting base 321 is equipped with a second synchronous transmission mechanism 322, which is in transmission cooperation with two sets of clamping assemblies 326 to drive the two sets of clamping assemblies 326 to move synchronously towards or away from each other in the horizontal direction. Specifically, the second synchronous transmission mechanism 322 includes a second motor 3221, a bidirectional lead screw 3222, and a lead screw mating block. The output shaft of the second motor 3221 is connected to the bidirectional lead screw 3222 via a coupling. The bidirectional lead screw 3222 has two external thread segments with opposite thread directions. There are two lead screw mating blocks, each threadedly mating with one of the two external thread segments. The cylinder fixing plate 3261 of each set of clamping assemblies 326 is fixed on a clamping plate base 325, which is connected to the corresponding lead screw mating block. The mounting base 321 is equipped with a second slide rail 323 extending in the left-right direction. A second slider 324 is slidably fitted on the second slide rail 323, and the clamping plate base 325 is connected to the corresponding second slider 324. When the second motor 3221 rotates forward or reverse, it drives the two lead screw mating blocks to move synchronously towards or away from each other through the bidirectional lead screw 3222, thereby driving the two sets of clamping components 326 to move synchronously towards or away from each other, so as to clamp PCB boards 5 of different widths.

[0041] A support plate is also installed on the side of the mounting base 321 facing away from the clamping assembly 326. Two first photoelectric switches 34, spaced apart in the left-right direction, are fixed on the support plate. A first trigger plate is provided on the clamping base 325 to trigger the first photoelectric switches 34. The first photoelectric switches 34 are used to limit the horizontal movement of the two sets of clamping assemblies 326. Before operation, the operator inputs the width of the PCB board 5 to be peeled through the human-machine interface. The controller controls the second motor 3221 to operate according to the input dimensions, automatically adjusting the spacing between the two clamping assemblies 326 to a suitable position.

[0042] The adhesive tape removal assembly 4 is located below the clamping plate assembly 3 and is used to remove the adhesive tape from the PCB board 5. Figure 10 and Figure 11As shown, the adhesive-tearing assembly 4 includes a transplanting mounting plate 41 and two sets of adhesive-tearing claw pairs 44. The transplanting mounting plate 41 is provided with a third synchronous transmission mechanism 42 for driving the two sets of adhesive-tearing claw pairs 44 to move synchronously in opposite directions or in opposite directions. Figure 12 and Figure 13 As shown, the third synchronous transmission mechanism 42 is a synchronous belt mechanism, including a third motor 421, a third driving pulley 422, a third driven pulley 423, and a third synchronous belt 424. The third motor 421 is fixed on the third base 45, which is assembled with the transplanting mounting plate 41. The output shaft of the third motor 421 is connected to the third driving pulley 422. The third driven pulley 423 is rotatably mounted on the transplanting mounting plate 41 and is spaced apart from the third driving pulley 422 in the left-right direction. The third synchronous belt 424 is wound around the third driving pulley 422 and the third driven pulley 423. Synchronous belt mounting plates 425 are respectively provided on the upper and lower sides of the third synchronous belt 424, and the synchronous belt mounting plates 425 clamp the third synchronous belt 424.

[0043] The adhesive-removing assembly 4 also includes a rotary adhesive-removing mechanism that corresponds one-to-one with the adhesive-removing claws 44. The rotary adhesive-removing mechanism includes a rotary cylinder 43 and a cylinder mounting base. Two synchronous belt mounting plates 425 are respectively connected to the corresponding cylinder mounting bases, and the two rotary cylinders 43 are respectively fixed on the corresponding cylinder mounting bases.

[0044] like Figure 12 As shown, to ensure more stable horizontal movement of the tearing claw pair 44, a third slide rail 426 with vertically spaced parallel arrangement is provided on the transplanting mounting plate 41. The upper and lower ends of the synchronous belt mounting plate 425 are respectively slidably engaged with the third slide rail 426 via third sliders. The transplanting mounting plate 41 is also equipped with a second photoelectric switch 46 for detecting the position of the tearing claw pair 44. Two second photoelectric switches 46 are provided, arranged at intervals in the left-right direction. One of the synchronous belt mounting plates 425 is equipped with a second trigger plate for triggering the second photoelectric switch 46.

[0045] like Figure 14 and Figure 15 As shown, the adhesive-tearing claw pair 44 includes a gripper cylinder 441 and two opposing adhesive-tearing claws 442. The two adhesive-tearing claws 442 are respectively connected to two pneumatic fingers of the gripper cylinder 441, and the gripper cylinder 441 realizes the opening and closing of the adhesive-tearing claw pair 44. One of the two adhesive-tearing claws 442 is provided with a toothed biting part 443, and the other is provided with a biting groove 444 that matches the toothed biting part 443 to increase the friction when gripping the adhesive tape. The toothed biting part 443 is a protrusion, and the adhesive-tearing claw pair 44 clamps the adhesive tape by the biting engagement of the toothed biting part 443 and the biting groove 444. An electro-proportional valve is connected in series in the air circuit of the gripper cylinder 441. The electro-proportional valve receives an analog signal from the controller and can steplessly adjust the output air pressure, thereby realizing the precise adjustment of the gripping force of the adhesive-tearing claws 442.

[0046] like Figure 14 As shown, the tops of the two tear-off claws 442 have inclined surfaces. When the tear-off claw pair 44 is closed, a V-shaped guide groove 445 is formed between the inclined surfaces of the two tear-off claws 442. This groove guides and corrects the slightly warped or misaligned head of the tape 6 when the tear-off claws 442 are close to the edge of the tape 6, guiding the head of the tape 6 to the effective clamping area in the center. Each of the two tear-off claws 442 is embedded with a detection probe 447. The detection end face of the detection probe 447 is flush with or slightly protrudes from the clamping surface of the tear-off claw 442. The tail ends of the two detection probes 447 are connected to the detection circuit of the controller via wires. The detection circuit can determine the continuity between the two detection probes 447. When the tear-off claw pair 44 is closed and there is no tape 6 between the two tear-off claws 442, the two detection probes 447 form a conductive loop. If the tearing claws 442 are closed and there is tape 6 between the two tearing claws 442, the two detection probes 447 will be isolated by the tape 6 and unable to conduct because the tape 6 is an insulating material. This detection method can determine whether the tearing claws 442 have successfully gripped the tape 6, avoiding rework.

[0047] To ensure smooth tape tearing, a tape tearing limit block 446 is provided between the two tape tearing jaws 442. The tape tearing limit block 446 is fixed on the cylinder body of the jaw cylinder 441 and moves horizontally together with the two tape tearing jaws 442 to flatten the tape 6 that is drooping.

[0048] The cylinder body of the gripper cylinder 441 is fixed to the rotary output end of the rotary cylinder 43, meaning the rotary cylinder 43 can drive the tearing gripper pair 44 to rotate, thereby enabling the degumming operation. A tape collection device 7 is located below the tearing assembly 4 on the frame 1. The tape collection device 7 is a tape collection trolley with a drawer-type structure, which can be pulled out from the side of the frame 1 for easy periodic cleaning of waste tape 6 by the operator. The rotary cylinder 43 can drive the entire tearing gripper pair 44 to rotate 180° around the horizontal axis, causing the opening of the tearing gripper 442 to face downwards. At this time, the tearing gripper 442 is released, and the tape 6 naturally falls into the tape collection device 7.

[0049] The specific working process of the vertical board edge degumming machine of the present invention is as follows: First, the lifting drive mechanism 21 drives the rotary drive mechanism 22 and the clamping plate assembly 3 to rise to the loading position. The output end of the rotary drive mechanism 22 is reset to the 0° reference position, keeping the mounting base plate 31 of the clamping plate assembly 3 vertical. The operator takes a PCB board 5 to be peeled off, measures the board length and width, and inputs the length and width dimensions of the PCB board 5 to be peeled off through the human-machine interface. According to the input parameters, the controller controls the second motor 3221 and the first motor 331 to start, automatically adjusting the distance between the two clamping units 32 to a position suitable for the current board length, and adjusting the distance between the two sets of clamping components 326 of each clamping unit 32 to a position suitable for the current board width.

[0050] Next, the second slide cylinders 3263 in both clamping units 32 extend, driving the second clamping blocks 3268 and the second abutment blocks 3270 on all the second rotary clamping cylinders 3266 to extend. At the same time, the two third slide cylinders 3264 in the upper clamping unit 32 extend, thereby driving the limiting members 3271 to extend. When placing the PCB board 5, the left and right sides of the PCB board 5 are respectively attached to the limiting surfaces on the second abutment blocks 3270, and the upper side is attached to the two limiting members 3271, realizing the rapid positioning of the PCB board 5. Then, each of the second rotary clamping cylinders 3266 is opened, so that each of the second clamping blocks 3268 cooperates with the corresponding second abutment blocks 3270 to clamp the left and right sides of the PCB board 5. After that, the two third slide cylinders 3264 retract, and the two limiting members 3271 are removed. The two sets of adhesive tearing claws 44 are in the initial avoidance position, in the open state, and the openings of the adhesive tearing claws 442 are facing upward.

[0051] First, use the adhesive peeler to peel off the tape from the bottom and top of the PCB board. Specifically, the lifting drive mechanism 21 drives the entire clamping plate assembly 3 to descend, so that the lower edge of the PCB board 5 extends into the gap between the two tearing claws 442 of the tearing claw pair 44. At this time, the claw cylinder 441 drives the tearing claw pair 44 to close. The clamping force of the claw cylinder 441 is adjusted by the electric proportional valve so that the tearing claws 442 maintain a very small clamping force. Then, the third synchronous transmission mechanism 42 drives the two sets of tearing claw pairs 44 to move synchronously in opposite directions until the tearing claw pairs 44 move to the outside of the PCB board 5. During this process, the tearing limit block 446 between the tearing claw pairs 44 moves synchronously with the tearing claws 442, flattening the tape 6 that may sag at the bottom of the PCB board 5 upwards, ensuring that the tape 6 exposed on both sides of the PCB board 5 enters the clamping area of ​​the tearing claw pair 44 smoothly. Then, the claw cylinder 441 retracts to clamp the tape 6 with the two tearing claws 442. The controller detects the gripping effectiveness using detection probes 447 embedded in the two adhesive-tearing claws 442. If the two detection probes 447 form a conductive circuit, it is determined that the tape 6 is not gripped. The controller controls the adhesive-tearing claws 442 to open, and the third synchronous transmission mechanism 42 re-drives the adhesive-tearing claws 442 to perform a secondary adhesive-strapping action until the detection probes 447 are isolated by the tape 6 to form an insulating circuit, confirming that the tape 6 is successfully gripped.

[0052] After confirming that the tape 6 has been successfully clamped, the third synchronous transmission mechanism 42 drives the two sets of tearing claws 44 to move synchronously towards each other. At the same time, the lifting drive mechanism 21 drives the entire clamping plate assembly 3 to move upward. The rising speed of the clamping plate assembly 3 matches the moving speed of the two sets of tearing claws 44, thereby tearing off the tape 6 on the bottom of the PCB board 5. After tearing, the two rotary cylinders 43 drive the two tearing claws 44 to rotate 180°. The claw cylinder 441 extends, causing the two tearing claws 442 to release the tape 6. The tape 6 falls into the tape collection device 7 below. Then the tearing claws 44 reset, waiting for the next action. The rotary drive mechanism 22 rotates the entire clamping plate assembly 3 and the PCB board 5 clockwise by 180°, so that the top of the PCB board 5 faces down and is aligned with the tearing assembly 4. The above actions are repeated to tear off the tape 6 on the top of the PCB board 5.

[0053] After the adhesive peeling claws reach 44, they peel off the tape 6 on the left and right sides of the PCB board 5. After the tape 6 on the PCB board 5 is peeled off, the lifting drive mechanism 21 drives the clamping plate assembly 3 to move upward to the set position. At this time, the rotation drive mechanism 22 drives the clamping plate assembly 3 to rotate counterclockwise by 90°, so that the left and right sides of the PCB board 5 are in the up and down position. At this time, each of the first rotary clamping cylinders 3265 is activated, so that each of the first clamping blocks 3267 cooperates with the corresponding first abutting block 3269 to clamp the upper (i.e., the left side of the original PCB board 5) and the lower (i.e., the right side of the original PCB board 5) of the PCB board 5. At the same time, each of the second rotary clamping cylinders 3266 opens the second clamping block 3268 to release the clamping of the PCB board 5, and retracts the second clamping block 3268 so as not to affect the subsequent adhesive peeling operation. After clamping the PCB board 5 again, the lifting drive mechanism 21 lowers the PCB board 5 to the adhesive removal position, and the adhesive removal claws 44 repeat the above action to remove the adhesive tape 6 on the right side of the PCB board 5. Then, the rotation drive mechanism 22 rotates the clamping assembly 3 180°, so that the left side of the PCB board 5 rotates to a downward position and the right side rotates to an upward position. At this time, the first clamping block 3267 clamping the left side of the PCB board 5 releases the PCB board 5 and retracts, leaving only the first clamping block 3267 clamping the right side of the PCB board 5 to hold it. Then, the lifting drive mechanism 21 lowers the PCB board 5 to the adhesive removal position, and the adhesive removal claws 44 repeat the above action to remove the adhesive tape 6 on the left side of the PCB board 5.

[0054] After all the tape 6 has been removed, the operator holds the PCB board 5 and triggers the corresponding switch, such as a foot switch, to release the first clamping block 3267, allowing the de-adhesive-free PCB board 5 to be removed and placed in the qualified product area. The equipment automatically resets to its initial state, awaiting the loading of the next PCB board 5. All the removed tape waste is automatically collected in the tape collection cart below the frame 1. When the waste reaches the preset capacity, the human-machine interface issues a cleaning prompt. The operator pulls the tape collection cart out from the side of the frame 1, emptys the waste, and pushes it back to its original position.

[0055] This invention uses a rotating PCB board 5, which allows for the removal of adhesive tape 6 from all four sides of the PCB board 5 with only one set of adhesive removal assembly 4. This simplifies the structure of the entire vertical board edge de-adhesive machine, reduces the number of transmission structures and drive sources, and makes maintenance more convenient.

[0056] In the above embodiments, the clamping plate assembly 3 is raised and lowered while the adhesive-removing assembly 4 remains in the same position. The adhesive tape 6 on the sheet material to be peeled is delivered to the peeling position of the adhesive-removing assembly 4 by moving the clamping plate assembly 3 downwards towards the adhesive-removing assembly 4. In other embodiments, the position of the clamping plate assembly 3 remains unchanged while the adhesive-removing assembly 4 is raised and lowered to bring the adhesive-removing assembly 4 closer to the clamping plate assembly 3. In this case, the rotary drive mechanism 22 is directly fixed to the frame 1, and the lifting drive mechanism 21 is positioned at the location of the adhesive-removing assembly 4, with the output end of the lifting drive mechanism 21 connected to the adhesive-removing assembly 4.

[0057] In the above embodiments, the lifting drive mechanism 21 adopts a structure with a dual slide module 212, a steering mechanism 215, and a single drive source. In other embodiments, the lifting drive mechanism 21 may also adopt other structural forms, such as a robotic arm, a single ball screw with dual guide rails, a gear and rack lifting mechanism with a servo motor driving the gear to move along a vertical rack, or a structure with a pneumatic lifting cylinder and a magnetic scale for positioning.

[0058] In the above embodiments, the adhesive-tearing assembly 4 employs two sets of adhesive-tearing claw pairs 44 capable of synchronously moving towards or away from each other, and the moving speed of the adhesive-tearing claw pairs 44 during the adhesive-tearing process matches the rising speed of the clamping plate assembly 3. In other embodiments, the movement and adhesive-tearing method of the adhesive-tearing claw pairs 44 can also adopt a single-set translational structure. For example, only one set of adhesive-tearing claw pairs 44 that can translate bidirectionally along the side of the board is retained. After clamping the adhesive tape, it moves at a constant speed from one side of the board to the other, while the clamping plate assembly 3 rises synchronously and the speeds of the two are matched to complete the adhesive-tearing process.

[0059] In the above embodiments, the adhesive-tearing claws 44 clamp the adhesive tape using a meshing method where one adhesive-tearing claw 442 has a toothed biting portion 443 and the other adhesive-tearing claw 442 has a matching biting groove 444. In other embodiments, the adhesive-tearing claws 442 can also use other structures to clamp the adhesive tape. For example, a silicone anti-slip pad can be attached to the clamping surface of one adhesive-tearing claw 442, and the clamping surface of the other adhesive-tearing claw 442 can be a hard alloy flat surface; or permanent magnets can be embedded in both adhesive-tearing claws 442 to clamp the adhesive tape using magnetic attraction.

[0060] In the above embodiments, the success of tape clamping is determined by the formation of a conductive or non-conductive circuit by the detection probes 447 embedded in the two tearing claws 442. In other embodiments, the tape clamping detection method can also take other forms, such as installing a thin-film pressure sensor on the clamping surface of the tearing claw 442 to determine whether the tape is clamped by the detected pressure value; or installing a laser displacement sensor on one side of the tearing claw 442 to determine the clamping distance by measuring the closing gap of the tearing claw 442, etc.

[0061] In the above embodiment, a tear-stopping block 446, which moves horizontally along with the two tear-off grippers 442, flattens the drooping tape. In other embodiments, the tape flattening structure can also take other forms, such as providing a vertically floating silicone roller in front of the tear-off grippers 442. When the tear-off grippers 442 move outward, the roller first contacts the drooping tape and flattens it upward.

[0062] In the above embodiments, the clamping plate assembly 3 uses a first synchronous transmission mechanism 33 to drive the two sets of clamping units 32 to move synchronously towards or away from each other in the vertical direction. In other embodiments, each set of clamping units 32 can also be provided with a separate drive source and transmission mechanism, and the two drive sources can be kept synchronized. Of course, based on the use of the first synchronous transmission mechanism 33 to drive the two sets of clamping units 32 to move synchronously towards or away from each other in the vertical direction, the first synchronous transmission mechanism 33 can also be in the form of a bidirectional lead screw 3222 as in the above embodiments.

[0063] In the above embodiments, the second synchronous transmission mechanism 322 is in transmission cooperation with the two sets of clamping assemblies 326 to drive the two sets of clamping assemblies 326 to move synchronously towards or away from each other in the horizontal direction. In other embodiments, a drive source and transmission mechanism can also be provided for each set of clamping assemblies 326 separately, and the two drive sources can be kept synchronized. Of course, based on the use of the second synchronous transmission mechanism 322 to drive the two sets of clamping assemblies 326 to move synchronously towards or away from each other in the horizontal direction, the second synchronous transmission mechanism 322 can also be a synchronous belt mechanism.

[0064] In the above embodiments, the clamping component 326 clamps the corresponding side of the PCB board 5 by means of a clamping block and an abutment block. In other embodiments, a vacuum suction cup can also be used to adsorb the PCB board 5 for clamping. For example, a matrix of vacuum nozzles can be arranged on the mounting substrate 31 to adsorb the surface of the PCB board 5 by vacuum suction. The adsorption state is maintained when flipping without changing the clamping position.

[0065] While various embodiments of the invention have been shown and described in this specification, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Many modifications, alterations, and alternatives will occur to those skilled in the art without departing from the spirit and essence of the invention.
