[0002] The PCB (Printed Circuit Board) is an electronic component electrical interconnection carrier. In the full-board resin plug hole process of the PCB and IC carrier board, in order to prevent the board edge process hole or the mounting plate from being contaminated by the resin, a protective film needs to be pasted on the four edges before the plug hole, and the adhesive film on the four edges needs to be torn off before entering the baking process after the plug hole is completed.

[0048] Please refer to Figures 1-18 The present application provides a vertical type automatic edge tearing machine, which comprises a base 1, a clamping device 2, a tearing assembly 3, a material taking and clamping assembly 10, a degumming assembly and a material collecting trolley 6.

[0049] Refer to Figures 1-8 The clamping device 2 is arranged on the front side of the base 1, and the clamping device 2 is used for clamping the upper and lower sides of the PCB board 8 to be torn, or for clamping the left and right sides of the PCB board 8. Specifically, the clamping device 2 comprises two vertical arms 20, a driving device 25, an upper clamping assembly 21, a lower clamping assembly 22, a left clamping assembly 23 and a right clamping assembly 24. Wherein, the two vertical arms 20 extend along the vertical direction and are slidably arranged on the base 1, and the driving device 25 is arranged on the base 1 and used for driving the two vertical arms 20 to move towards each other or to move away from each other. The top of each vertical arm 20 is provided with the upper clamping assembly 21, and the bottom of each vertical arm 20 is provided with the lower clamping assembly 22, and the upper clamping assembly 21 and the lower clamping assembly 22 are respectively used for clamping the upper and lower sides of the PCB board 8.

[0050] Refer to Figures 1-8The upper clamping assembly 21 is provided with two groups, that is, one group of upper clamping assemblies 21 is arranged on the top of each stand arm 20. The upper clamping assembly 21 comprises a second telescopic structure 210, a second telescopic rotary cylinder 211, a third clamping block 212 and a fourth clamping block 213. The second telescopic structure 210 is fixed on the stand arm 20 through a connecting plate. The second telescopic rotary cylinder 211 is fixedly connected with the telescopic end of the second telescopic structure 210. The second telescopic structure 210 is used to drive the second telescopic rotary cylinder 211 to move in the front-rear direction of the machine base 1. The third clamping block 212 is fixed on the cylinder body of the second telescopic rotary cylinder 211. The fourth clamping block 213 is drivingly connected with the output end of the second telescopic rotary cylinder 211. The second telescopic rotary cylinder 211 is used to drive the fourth clamping block 213 to rotate and drive the fourth clamping block 213 to telescope in the front-rear direction of the machine base 1. When the upper sides of the left and right ends of the PCB board 8 are respectively in the clamping channels of the two upper clamping assemblies 21, the second telescopic rotary cylinder 211 of each upper clamping assembly 21 drives the fourth clamping block 213 of each upper clamping assembly 21 to retract, so that the clamping channel between the third clamping block 212 and the fourth clamping block 213 clamps the PCB board 8.

[0051] Referring to Figures 1-8 The lower clamping assembly 22 is provided with two groups, that is, one group of lower clamping assemblies 22 is arranged on the bottom of each stand arm 20. The lower clamping assembly 22 is slidably arranged on the stand arm 20 through a sliding seat 201. The sliding seat 201 is located below the upper clamping assembly 21. The sliding seat 201 can slide in the vertical direction of the stand arm 20. The lower clamping assembly 22 comprises a third telescopic structure 220, a third telescopic rotary cylinder 221, a fifth clamping block 222 and a sixth clamping block 223. The third telescopic structure 220 is connected with the stand arm 20 through the sliding seat 201. The third telescopic rotary cylinder 221 is fixedly connected with the telescopic end of the third telescopic structure 220. The third telescopic structure 220 is used to drive the third telescopic rotary cylinder 221 to move in the front-rear direction of the machine base 1. The fifth clamping block 222 is fixed on the cylinder body of the third telescopic rotary cylinder 221. The sixth clamping block 223 is drivingly connected with the output end of the third telescopic rotary cylinder 221. The third telescopic rotary cylinder 221 is used to drive the sixth clamping block 223 to rotate and drive the sixth clamping block 223 to telescope in the front-rear direction of the machine base 1. In the state that the upper clamping assembly 21 and the lower clamping assembly 22 do not clamp and fix the PCB board 8, the fourth clamping block 213 of the upper clamping assembly 21 is in a horizontal state, and the sixth clamping block 223 of the lower clamping assembly 22 is in a horizontal state. In addition, the left clamping assembly 23 is arranged on one of the stand arms 20, and the right clamping assembly 24 is arranged on the other stand arm 20. The left clamping assembly 23 and the right clamping assembly 24 are respectively used to clamp the left and right sides of the PCB board 8. The left clamping assembly 23 on one stand arm 20 is located below the upper clamping assembly 21 on the stand arm 20. The right clamping assembly 24 on the other stand arm 20 is located below the upper clamping assembly 21 on the stand arm 20.

[0052] The left clamping assembly 23 is provided with two groups, and the right clamping assembly 24 is also provided with two groups. The two groups of left clamping assemblies 23 are respectively arranged on the top of a vertical arm 20 and on the sliding seat 201 of the vertical arm 20. The two groups of right clamping assemblies 24 are respectively arranged on the top of another vertical arm 20 and on the sliding seat 201 of the vertical arm 20. The left clamping assembly 23 at the bottom and the right clamping assembly 24 at the bottom can be respectively lifted up and down with the two groups of lower clamping assemblies 22.

[0053] It should be noted that, in the state that the upper clamping assembly 21 and the lower clamping assembly 22 clamp the PCB board 8, the left clamping assembly 23 and the right clamping assembly 24 are not in contact with the PCB board 8. In the state that the left clamping assembly 23 and the right clamping assembly 24 clamp the PCB board 8, the upper clamping assembly 21 and the lower clamping assembly 22 are not in contact with the PCB board 8.

[0054] The left clamping assembly 23 comprises a fourth telescopic structure 230, a fourth telescopic rotary cylinder 231, a seventh clamping block 232 and an eighth clamping block 233. The fourth telescopic structure 230 is fixed on a vertical arm 20, and the fourth telescopic structure 230 is drivingly connected with the fourth telescopic rotary cylinder 231 for driving the fourth telescopic rotary cylinder 231 to move in the front-rear direction of the machine base 1. The seventh clamping block 232 is fixed on the cylinder body of the fourth telescopic rotary cylinder 231, and the eighth clamping block 233 is fixed on the output end of the fourth telescopic rotary cylinder 231. When the left side of the PCB board 8 is located in the clamping channel formed between the seventh clamping block 232 and the eighth clamping block 233, the fourth telescopic rotary cylinder 231 drives the eighth clamping block 233 to rotate 90° and retract, so that the clamping channel between the seventh clamping block 232 and the eighth clamping block 233 clamps the left side of the PCB board 8.

[0055] It should be noted that, in the state that the left clamping assembly 23 does not clamp the PCB board 8, the eighth clamping block 233 is in a vertical state. In addition, since the left clamping assembly 23 and the right clamping assembly 24 have the same structure, the structure of the right clamping assembly 24 will not be described here.

[0056] When the transplanting and carrying mechanism or the mechanical hand of the previous process clamps the PCB board to be torn and moves into the corresponding position of the tearing machine of the present embodiment, the transplanting and carrying mechanism or the mechanical hand clamps the left and right sides of the PCB board. The upper clamping assembly 21 and the lower clamping assembly 22 of the tearing machine clamp the upper and lower sides of the PCB board to be torn, so as to clamp, position and fix the incoming PCB board. At this time, the transplanting and carrying mechanism or the mechanical hand releases the clamping of the PCB board and moves out of the tearing machine.

[0057] Specifically, it can be understood that after the transplanting carrying mechanism or the mechanical hand of the previous process clamps the PCB to be torn and moves into the corresponding position of the tearing machine of the embodiment, the upper clamping assembly 21 and the lower clamping assembly 22 act simultaneously, the second telescopic structure 210 of the upper clamping assembly 21 drives the second telescopic rotary cylinder 211 to drive the fourth clamping block 213 to abut against the upper side of the board surface of the PCB 8, and the third telescopic structure 220 of the lower clamping assembly 22 drives the third telescopic rotary cylinder 221 to drive the sixth clamping block 223 to abut against the lower side of the board surface of the PCB 8. At this time, the second telescopic rotary cylinder 211 of the upper clamping assembly 21 drives the fourth clamping block 213 to rotate 90° and drives the fourth clamping block 213 to move forward, and the third telescopic rotary cylinder 221 of the lower clamping assembly 22 drives the sixth clamping block 223 to rotate 90° and drives the sixth clamping block 223 to move forward, so that the upper clamping assembly 21 and the lower clamping assembly 22 clamp the PCB 8 simultaneously.

[0058] The second telescopic structure 210 and the first telescopic structure 1030 of the embodiment can both be selected as telescopic cylinders. Of course, in other embodiments, the second telescopic structure 210 and the first telescopic structure 1030 can both be selected as electric push rods, which are not limited here.

[0059] In addition, the sliding seat 201 on each vertical arm 20 is connected with a lifting structure 202, and the lifting structure 202 is used to drive the sliding seat 201 to ascend and descend along the vertical arm 20, so as to adjust the distance between the lower clamping assembly 22 and the upper clamping assembly 21. Since the two vertical arms 20 can move towards or away from each other along the left-right direction of the machine base 1 under the drive of the driving device 25, the distance between the left clamping assembly 23 and the right clamping assembly 24 can be adjusted, so that the clamping device 2 of the embodiment can be suitable for clamping and fixing PCBs 8 of different sizes.

[0060] It should be noted that the driving device 25 includes a first screw rod driving mechanism 251 and a second screw rod driving mechanism 252, the first screw rod driving mechanism 251 is used to drive one vertical arm 20 to slide along the left-right direction of the machine base 1, and the second screw rod driving mechanism 252 is used to drive the other vertical arm 20 to slide along the left-right direction of the machine base 1. In addition, the lifting structure 202 can also be selected as a screw rod driving mechanism. Since the screw rod driving mechanism described above belongs to a mechanical conventional structure and is prior art, it is not repeated here.

[0061] Referring to Figure 1 , Figures 9-17The tearing assembly 3 is arranged at the rear side of the base 1, and comprises left and right tearing devices and up and down tearing devices. The left and right tearing devices comprise a driving unit, a left connecting arm 301, a right connecting arm 31, a left tearing assembly 32 and a right tearing assembly 33. The left and right connecting arms 301 and 31 extend in the vertical direction and are movably arranged at the left and right sides of the rear side of the base 1 respectively. The driving unit is arranged on the base 1 and is used to drive the left and right connecting arms 301 and 31 to move towards or away from each other. The left and right tearing assemblies 32 and 33 are arranged on the left and right connecting arms 301 and 31 respectively, and are used to tear the left and right adhesive films 80 on the PCB 8 respectively.

[0062] The structure of the driving unit is the same as that of the driving device 25, and will not be described here.

[0063] The structure of the right tearing assembly 33 is the same as that of the left tearing assembly 32.

[0064] With reference to Figure 9 、 Figure 14 and Figure 17 , the right tearing assembly 33 comprises a right lifting mechanism 330 and a right tearing component. The right lifting mechanism 330 is arranged on the right connecting arm 31 and is used to drive the right tearing component to lift up and down. Specifically, the right tearing component comprises a right connecting seat 332, a telescopic tearing clamp jaw mechanism 333 and a telescopic rotating tearing mechanism 334. The right connecting seat 332 is arranged on the right connecting arm 31 in the vertical direction and is connected with the lifting end of the right lifting mechanism 330. The telescopic tearing clamp jaw mechanism 333 and the telescopic rotating tearing mechanism 334 are arranged on the right connecting seat 332. The telescopic tearing clamp jaw mechanism 333 is used to clamp the top end of the adhesive film 80 on the right side of the PCB 8 and tear the adhesive film 80 on the right side of the PCB 8 to a certain angle. The telescopic rotating tearing mechanism 334 is used to clamp the adhesive film 80 peeled off by the telescopic tearing clamp jaw mechanism 333 and rotate the adhesive film 80 on the right side of the PCB 8 by 360° to tear it downward. Thus, it can be understood that, in the state that the upper clamping assembly 21 and the lower clamping assembly 22 clamp the upper and lower sides of the PCB 8 respectively, the right tearing assembly 33 tears the adhesive film 80 on the right side of the PCB 8 to a certain angle through the telescopic tearing clamp jaw mechanism 333, then clamps the adhesive film 80 peeled off by the telescopic tearing clamp jaw mechanism 333 through the telescopic rotating tearing mechanism 334 of the right tearing assembly 33, and rotates it by 360° and tears it downward, so as to complete the tearing action of the adhesive film 80 on the right side of the PCB 8.

[0065] Similarly, in the state that the upper clamping assembly 21 and the lower clamping assembly 22 clamp the upper and lower sides of the PCB board 8 respectively, the left adhesive film 80 on the left side of the PCB board 8 is torn off at a certain angle by the telescopic adhesive film tearing jaw mechanism 333 of the left adhesive film tearing assembly 32, and then the adhesive film 80 peeled off by the telescopic adhesive film tearing jaw mechanism 333 is clamped by the telescopic rotary adhesive film tearing mechanism 334 of the left adhesive film tearing assembly 32, and is rotated by 360 degrees and torn downward, that is, the adhesive film tearing action of the left adhesive film 80 on the PCB board 8 is completed.

[0066] Of course, when the adhesive film tearing action of the left and right adhesive films 80 on the PCB board 8 is performed, the upper clamping assembly 21 and the lower clamping assembly 22 act simultaneously, so that the left and right adhesive films 80 on the PCB board 8 are torn off simultaneously, improving the adhesive film tearing efficiency.

[0067] Since the right connecting seat 332 can be lifted up and down along the right connecting arm 31, and the telescopic adhesive film tearing jaw mechanism 333 and the telescopic rotary adhesive film tearing mechanism 334 of the right adhesive film tearing assembly 33 are both fixed on the right connecting seat 332, the telescopic adhesive film tearing jaw mechanism 333 and the telescopic rotary adhesive film tearing mechanism 334 of the right adhesive film tearing assembly 33 can be lifted up and down. Here, the specific structure of the telescopic adhesive film tearing jaw mechanism 333 of the right adhesive film tearing assembly 33 is described in detail. The telescopic adhesive film tearing jaw mechanism 333 includes a pneumatic jaw 3330, a mounting plate 3331 and a first driving module 3332. The first driving module 3332 is fixed on the right connecting seat 332, the mounting plate 3331 is connected with the first driving module 3332, the first driving module 3332 is a linear module, the first driving module 3332 is used to drive the mounting plate 3331 to move in the front-rear direction of the machine base 1, and the pneumatic jaw 3330 is fixed on the mounting plate 3331. In this way, the pneumatic jaw 3330 can not only be lifted up and down, but also move in the front-rear direction of the machine base 1, so that the pneumatic jaw 3330 can clamp the top of the adhesive film 80 on the right side of the PCB board 8.

[0068] It should be noted that since the adhesive tape is flexible, the top end of the adhesive film 80 on the right side of the PCB board 8 can be downward, in order to avoid the failure of the pneumatic jaw 3330 clamping the top end of the adhesive film 80 on the right side of the PCB board 8, the pneumatic jaw 3330 of the present embodiment moves from bottom to top along the adhesive film 80 on the right side of the PCB board 8, and the pneumatic jaw 3330 is opened at the same time, while ensuring that the adhesive film 80 on the right side of the PCB board 8 is within the clamping range of the pneumatic jaw 3330. After the pneumatic jaw 3330 moves from bottom to top to the top end position of the adhesive film 80 on the right side of the PCB board 8, the pneumatic jaw 3330 is clamped, thereby avoiding the pneumatic jaw 3330 clamping the top end of the adhesive film 80 on the right side of the PCB board 8.

[0069] Here, the specific structure of the telescopic rotary tearing mechanism 334 of the right tearing assembly 33 is described in detail. The telescopic rotary tearing mechanism 334 of the right tearing assembly 33 includes a first telescopic unit 3340, a first rotary clamp jaw 3341, a connecting disc 3343, a film winding rod 3344, and a first power unit 3342. The first telescopic unit 3340 is fixed on the right connecting seat 332. The first power unit 3342 is selected from a driving motor. The first power unit 3342 is fixed on the first telescopic unit 3340. The first telescopic unit 3340 can be selected from a linear module. The output end of the first power unit 3342 is connected with the first rotary clamp jaw 3341. The first power unit 3342 is used to drive the first rotary clamp jaw 3341 to rotate 360°. The first rotary clamp jaw 3341 is used to clamp the adhesive film 80 peeled off by the telescopic tearing clamp jaw mechanism 333. The first telescopic unit 3340 is used to drive the first power unit 3342 to drive the first rotary clamp jaw 3341 to telescope along the horizontal front-back direction of the machine base 1, so that the first rotary clamp jaw 3341 can clamp the adhesive film 80 peeled off at a certain angle on the right side of the PCB board 8. In the state that the first rotary clamp jaw 3341 clamps the adhesive film 80 peeled off at a certain angle on the right side of the PCB board 8, the first rotary clamp jaw 3341 is driven by the first power unit 3342 to rotate 360°. At the same time, under the driving of the right lifting mechanism 330, the first rotary clamp jaw 3341 and the pneumatic clamp jaw 3330 descend along the right connecting arm 31, so that the adhesive film 80 on the right side of the PCB board 8 can be completely torn off.

[0070] It should be noted that the telescopic rotary tearing mechanism 334 and the telescopic tearing clamp jaw mechanism 333 interact with each other, which can avoid the adhesive film 80 from being broken during the tearing process, thereby avoiding the phenomenon that the adhesive film 80 is not completely torn off. For example, the telescopic tearing clamp jaw mechanism 333 can provide stable clamping force to ensure that the adhesive film 80 does not loosen or fall off during rotation. Specifically, the pneumatic clamp jaw 3330 plays a role in clamping and fixing the adhesive film 80, and the first rotary clamp jaw 3341 plays a role in rotating and peeling off the adhesive film 80. The two cooperate with each other. When the adhesive film 80 is torn in a rotary manner, the adhesive film 80 will be gradually peeled off along the circumferential direction of rotation. The stress is gradually transmitted and dispersed along the circumferential direction, rather than concentrated on a straight line. That is, the stress is dispersed on a larger area of the adhesive film 80. Compared with the single straight-line tearing mode, the rotary tearing mode can make the stress distribution more uniform, thereby avoiding the stress being too large at a local point of the adhesive film 80 and causing the adhesive film 80 to break.

[0071] Referring to Figure 17In order to facilitate the peeling of the film 80 from the first rotating clamp jaw 3341, the first rotating clamp jaw 3341 is connected to the first power unit 3342 through a connecting disc 3343, a plurality of film winding rods 3344 are fixed on the connecting disc 3343, the plurality of film winding rods 3344 are uniformly distributed along the circumference of the connecting disc 3343, and the plurality of film winding rods 3344 are located at the periphery of the first rotating clamp jaw 3341. In this way, the film 80 can be wound on the plurality of film winding rods 3344.

[0072] Since the structure of the right film peeling assembly 33 is the same as that of the left film peeling assembly 32, and the film peeling manner of the right film peeling assembly 33 is the same as that of the left film peeling assembly 32, the structure of the left film peeling assembly 32 will not be described here.

[0073] The action of the left film peeling assembly 32 clamping the top end of the film 80 on the left side of the PCB board 8 is the same as that of the right film peeling assembly 33 clamping the top end of the film 80 on the right side of the PCB board 8, and thus will not be described here.

[0074] The up-and-down film peeling device includes the upper film peeling device 4 and the lower film peeling device 5.

[0075] Referring to Figures 9-17 The upper film peeling device 4 includes an upper driving mechanism 40 and an upper film peeling assembly 41, both ends of the upper driving mechanism 40 are fixed at the top of the left connecting arm 301 and the right connecting arm 31 respectively, the upper driving mechanism 40 is drivingly connected with the upper film peeling assembly 41, and the upper driving mechanism 40 is used to drive the upper film peeling assembly 41 to move along the left-right direction of the machine base 1, so that the upper film peeling assembly 41 peels the upper side film 80 on the PCB board 8. The upper driving mechanism 40 of the present embodiment selects an existing screw rod driving structure, which will not be described here.

[0076] Referring to Figures 9-15 The upper film peeling assembly 41 includes an upper film peeling component 410 and an upper adhesive tape supporting and flattening assembly 411; the upper film peeling component 410 is arranged on the upper driving mechanism 40, and is used to clamp one end of the film 80 on the upper side of the PCB board 8 and peel the film 80 on the upper side of the PCB board 8 to a set angle; the upper adhesive tape supporting and flattening assembly 411 is arranged on the upper driving mechanism 40, and is used to support and flatten the film 80 peeled by the upper film peeling component 410. The upper film peeling assembly 41 of the present embodiment cooperates with the upper adhesive tape supporting and flattening assembly 411 and the upper film peeling component 410 to ensure that the film 80 on the upper side of the PCB board 8 is smoothly and completely peeled.

[0077] In particular, referring to Figures 9-15The upper tearing component 410 includes an upper connecting seat 4100, a third telescopic unit 4101 and an upper rotating tearing mechanism 4102. The upper connecting seat 4100 is connected with the upper driving mechanism 40. The third telescopic unit 4101 is arranged on the upper connecting seat 4100 in the vertical direction. The telescopic end of the third telescopic unit 4101 is connected with the upper rotating tearing mechanism 4102. The upper rotating tearing mechanism 4102 is used for clamping one end of the adhesive film 80 on the upper side of the PCB board 8. The third telescopic unit 4101 drives the upper rotating tearing mechanism 4102 to rise, so that the adhesive film 80 on the upper side of the PCB board 8 is torn to a set angle. The third telescopic unit 4101 of the embodiment can be a linear module or a telescopic cylinder, which is not limited here.

[0078] With reference to Figures 9-15 The upper rotating tearing mechanism 4102 includes a second rotating clamp jaw 41021 and a second power unit 41022. The second power unit 41022 is fixed on the third telescopic unit 4101. The second rotating clamp jaw 41021 is connected with the output end of the second power unit 41022. The second power unit 41022 is also a driving motor. The second power unit 41022 is used for driving the second rotating clamp jaw 41021 to rotate by 360°. The third telescopic unit 4101 drives the second power unit 41022 to drive the second rotating clamp jaw 41021 to rise and fall. When the second rotating clamp jaw 41021 clamps one end of the adhesive film 80 on the upper side of the PCB board 8, the third telescopic unit 4101 drives the second power unit 41022 to drive the second rotating clamp jaw 41021 to rise, so that the adhesive film 80 on the upper side of the PCB board 8 is torn to a set angle. It should be noted that since the adhesive tape is flexible, one end of the adhesive film 80 on the upper side of the PCB board 8 can be downward. In order to avoid the failure of clamping one end of the adhesive film 80 on the upper side of the PCB board 8 by the second rotating clamp jaw 41021, the second rotating clamp jaw 41021 moves from left to right along the adhesive film 80 on the upper side of the PCB board 8, and the second rotating clamp jaw 41021 is opened at the same time. Meanwhile, it is ensured that the adhesive film 80 on the upper side of the PCB board 8 is within the clamping range of the clamp jaw. After the second rotating clamp jaw 41021 moves from left to right to the position of one end of the adhesive film 80 on the upper side of the PCB board 8, the second rotating clamp jaw 41021 is clamped, so as to avoid clamping one end of the adhesive film 80 on the upper side of the PCB board 8 by the second rotating clamp jaw 41021.

[0079] With reference to Figures 9-15The upper adhesive tape supporting and flattening assembly 411 comprises a fourth telescopic unit 412, a fifth telescopic unit 413, a supporting and flattening wheel 414 and a connecting block 415. The fifth telescopic unit 413 is horizontally arranged on the upper connecting seat 4100, the fourth telescopic unit 412 is fixed along the vertical direction at the telescopic end of the fifth telescopic unit 413, the fifth telescopic unit 413 is used to drive the fourth telescopic unit 412 to move along the front and back directions of the machine base 1, the connecting block 415 is fixedly connected with the telescopic end of the fourth telescopic unit 412, and the fourth telescopic unit 412 is used to drive the connecting block 415 to move up and down. The supporting and flattening wheel 414 is arranged on the connecting block 415 and can support the upper side adhesive film 80 of the PCB 8. It can be understood that when the second rotary jaw 41021 of the upper rotary tearing adhesive film mechanism 4102 clamps one end of the upper side adhesive film 80 of the PCB 8 and moves up to tear the adhesive film 80 to a certain angle, the fourth telescopic unit 412 drives the connecting block 415 to drive the supporting and flattening wheel to move down to below the upper side adhesive film 80 torn to a certain angle, then the fifth telescopic unit 413 drives the connecting block 415 to drive the supporting and flattening wheel 414 to move to the position directly below the upper side adhesive film 80 torn to a certain angle, at this time, the fourth telescopic unit 412 drives the connecting block 415 to drive the supporting and flattening wheel to move up, so that the supporting and flattening wheel of the upper adhesive tape supporting and flattening assembly 411 supports the adhesive film 80 peeled by the upper tearing adhesive film component 410 to a horizontal state, so as to ensure that the second rotary jaw 41021360° rotates and tears the upper side adhesive film 80 of the PCB 8 from right to left.

[0080] It should be noted that when the upper side adhesive film 80 of the PCB 8 is torn, the second rotary jaw 41021 of the upper rotary tearing adhesive film mechanism 4102 clamps one end of the upper side adhesive film 80 of the PCB 8 and tears the adhesive film 80 to a certain angle, the supporting and flattening wheel of the upper adhesive tape supporting and flattening assembly 411 supports the adhesive film 80 torn by the second rotary jaw 41021 to a horizontal state with the clamping point of the adhesive film 80, at this time, the upper connecting seat 4100 is driven by the upper driving mechanism 40 to move from right to left, thereby driving the upper adhesive tape supporting and flattening assembly 411 and the upper rotary tearing adhesive film mechanism 4102 to move from right to left, and the second power unit 41022 of the upper rotary tearing adhesive film mechanism 4102 drives the second rotary jaw 41021360° to rotate, so that the upper tearing adhesive film assembly 41 achieves the purpose of rotating and tearing the adhesive film from right to left, and ensures that the upper side adhesive film 80 of the PCB 8 is torn smoothly.

[0081] Referring to Figure 14 , Figure 17The adhesive peeling device 5 includes a lower drive mechanism 50 and an adhesive peeling assembly 51. The two ends of the lower drive mechanism 50 are respectively disposed on the left connecting arm 301 and the right connecting arm 31. Specifically, the two ends of the lower drive mechanism 50 are respectively fixed to the left connecting seat 320 on the left connecting arm 301 and the right connecting seat 332 on the right connecting arm 31. The lower drive mechanism 50 is located below the left adhesive peeling assembly 32 and the right adhesive peeling assembly 33. The lower drive mechanism 50 is driven to the adhesive peeling assembly 51, and is used to drive the adhesive peeling assembly 51 to move in the left-right direction along the base 1, so that the adhesive peeling assembly 51 peels off the lower adhesive film 80 on the PCB board 8.

[0082] Reference Figure 14 , Figure 17 The lower adhesive peeling assembly 51 includes a lower adhesive peeling component 510 and a lower adhesive tape flattening assembly 511. The lower adhesive peeling component 510 includes a lower connecting seat 5101 and a lower rotating adhesive peeling mechanism 5102. The lower connecting seat 5101 is connected to the lower driving mechanism 50, and the lower rotating adhesive peeling mechanism 5102 is disposed on the lower connecting seat 5101. The lower rotating adhesive peeling mechanism 5102 is used to clamp one end of the adhesive film 80 on the lower side of the PCB board 8. Since the lower driving mechanism 50 can descend with the left connecting seat 320 and the right connecting seat 332, the lower rotating adhesive peeling mechanism 5102 can also descend with the lower driving mechanism 50. Specifically, since the right lifting mechanism 330 is used to drive the right connecting seat 332 to rise and fall, and the left lifting mechanism 321 drives the left connecting seat 320 to rise and fall, the right lifting mechanism 330 and the left lifting mechanism 321 are driven synchronously, so that the left connecting seat 320 and the right connecting seat 332 descend synchronously, thereby causing the lower driving mechanism 50 to descend.

[0083] The lower rotating adhesive tearing mechanism 5102 has the same structure as the upper rotating adhesive tearing mechanism 4102; the lower tape flattening assembly 511 has the same structure as the upper tape flattening assembly 411, and will not be described here.

[0084] Since the action of the lower rotating adhesive peeling mechanism 5102 clamping one end of the adhesive film 80 on the lower side of the PCB board 8 is the same as that of the upper rotating adhesive peeling mechanism 4102 clamping one end of the adhesive film 80 on the upper side of the PCB board 8, it will not be described in detail here.

[0085] After the second rotating jaw 41021 of the current rotating adhesive tearing mechanism 5102 clamps one end of the adhesive film 80 on the lower side of the PCB board 8, the second rotating jaw 41021 continues to descend, which can tear the adhesive film 80 on the lower side of the PCB board 8 to the set angle.

[0086] It should be noted that when performing the adhesive peeling action on the lower side of PCB board 8, refer to... Figure 17The second rotating gripper of the lower rotating tearing mechanism 5102 clamps one end of the adhesive film 80 on the lower side of the PCB 8 and tears a certain angle, the supporting wheel of the lower adhesive tape supporting and flattening assembly 511 supports and flattens the adhesive film 80 torn by the second rotating gripper 41021 of the lower rotating tearing mechanism 5102, so that the adhesive film 80 is supported to be horizontal with the clamping point of the adhesive film 80. At this time, the lower connecting seat 5101 is driven to move from right to left by the lower driving mechanism 50, and the lower adhesive tape supporting and flattening assembly 511 and the lower rotating tearing mechanism 5102 are driven to move from right to left, and the second power unit 41022 of the lower rotating tearing mechanism 5102 drives the second rotating gripper 41021 to rotate 360°, so that the lower tearing assembly 51 can achieve the purpose of rotating and tearing from right to left, and ensure that the adhesive film 80 on the lower side of the PCB 8 is successfully torn off.

[0087] The lower driving mechanism 50 of the embodiment is selected from the existing screw rod driving structure, which is not described here.

[0088] Referring to Figure 1 , Figure 3 , Figure 6 and Figure 18 , the material taking and clamping assembly 10 is arranged on the top of the machine base 1, and is used for fixing the PCB 8 after tearing the adhesive tape. That is, it can be understood that the PCB 8 after tearing the adhesive tape is clamped and fixed by the material taking and clamping assembly 10. In the state that the PCB 8 after tearing the adhesive tape is clamped and fixed by the material taking and clamping assembly 10, the clamping device releases the clamping of the PCB 8 after tearing the adhesive tape.

[0089] Specifically, the material taking and clamping assembly 10 includes a fixed seat 101, a positioning sensor 102 and two sets of positioning and clamping assemblies 103. The fixed seat 101 is fixed on the top of the machine base 1, and the positioning and clamping assemblies 103 are fixed on the fixed seat 101 in the left-right direction of the machine base 1. The positioning sensor 102 is controlled by the electric control box of the automatic adhesive tearing machine of the embodiment, and is fixed on the fixed seat 101 and used for identifying whether there is a PCB 8 on the positioning and clamping assembly 103.

[0090] It should be noted that, referring to Figure 6 , the two positioning and clamping assemblies 103 are the same in structure.

[0091] Referring to Figure 1 , Figure 3 and Figure 6, the positioning and clamping assembly 103 comprises a first telescopic structure 1030, a first telescopic rotary cylinder 1031, a first clamping block 1032 and a second clamping block 1033, the first telescopic structure 1030 is fixed on the fixed seat 101, the first telescopic rotary cylinder 1031 is fixedly connected with the telescopic end of the first telescopic structure 1030, the first telescopic structure 1030 is used for driving the first telescopic rotary cylinder 1031 to move along the front and back directions of the machine base 1; the first clamping block 1032 is fixed on the cylinder body of the first telescopic rotary cylinder 1031, the second clamping block 1033 is drivingly connected with the output end of the first telescopic rotary cylinder 1031, the first clamping block 1032 is located below the rotary rod of the first telescopic rotary cylinder 1031, and the first telescopic rotary cylinder 1031 is used for driving the second clamping block 1033 to rotate and driving the second clamping block 1033 to telescope along the front and back directions of the machine base 1.

[0092] , the first clamping block 1032 and the second clamping block 1033 can form a clamping channel for clamping the PCB board 8, in the state that the PCB board with the adhesive removed is not clamped and fixed, the first telescopic rotary cylinder 1031 drives the second clamping block 1033 to be in a horizontal state, and the clamping channel between the first clamping block 1032 and the second clamping block 1033 is in an open state; when the four adhesive tapes on the PCB board 8 are all removed, the first telescopic rotary cylinder 1031 drives the second clamping block 1033 to rotate by 90°, at this time, the first clamping block 1032 and the second clamping block 1033 form a clamping channel, and the second clamping block 1033 is driven by the first telescopic rotary cylinder 1031 to move towards the first clamping block 1032, so that the clamping channel between the first clamping block 1032 and the second clamping block 1033 clamps the PCB board 8 with the adhesive removed, at this time, the clamping device releases the clamping of the PCB board 8 with the adhesive removed, and the transplanting and carrying mechanism or the mechanical hand moves to clamp and fix the left and right sides of the PCB board 8 with the adhesive removed, at this time, the positioning and clamping assembly 103 releases the clamping of the PCB board 8 with the adhesive removed, and the transplanting and carrying mechanism or the mechanical hand takes out the PCB board 8 with the adhesive removed, to complete the automatic taking of the PCB board with the adhesive removed. Referring to Figure 4 and Figure 14 , the material collecting trolley 6 is arranged in the machine base 1, and the adhesive removing assembly is used for removing the adhesive film 80 torn off by the upper adhesive tearing assembly 41 or the lower adhesive tearing assembly 51, the left adhesive tearing assembly 32 and the right adhesive tearing assembly 33 to the material collecting trolley 6 for collection.

[0093] Specifically, referring to Figure 1 , Figure 14 , Figure 16 and Figure 17The degumming assembly includes an upper degumming film unit 7, a lower degumming film unit 71, a left degumming film unit 72 and a right degumming film unit 73, the upper degumming film unit 7, the lower degumming film unit 71, the left degumming film unit 72 and the right degumming film unit 73 are arranged on the machine base 1, and the upper degumming film unit 7, the lower degumming film unit 71, the left degumming film unit 72 and the right degumming film unit 73 are respectively used for stripping the adhesive film 80 torn off by the upper tearing assembly 41 or the lower tearing assembly 51, the left tearing assembly 32 and the right tearing assembly 33 into the material collecting trolley 6.

[0094] Hereinafter, the right degumming film unit 73 is specifically described; refer to Figure 17 The right degumming film unit 73 includes a right fork 730 and a second driving module 731, the second driving module 731 is fixed on the right connecting seat 332, and is used for driving the right fork 730 to move along the left-right direction of the machine base 1, so that the plurality of film winding rods 3344 on the right tearing assembly 33 can enter the slot of the right fork 730.

[0095] Refer to Figure 1 , Figure 14 and Figure 17 When it is needed to strip the adhesive film 80 wound on the film winding rod 3344 of the right tearing assembly 33, the plurality of film winding rods 3344 of the right tearing assembly 33 enter the slot of the right fork 730, the first rotating jaw 3341 and the pneumatic jaw 3330 of the right tearing assembly 33 are both in the open state, the first telescopic unit 3340 of the right tearing assembly 33 drives the first power unit 3342 of the right tearing assembly 33 to drive the first rotating jaw 3341 of the right tearing assembly 33 to move along the rear side direction of the machine base 1, the adhesive film 80 wound on the plurality of film winding rods 3344 of the right tearing assembly 33 is stripped off under the action of the right fork 730, and the stripped adhesive film 80 can enter the material collecting trolley 6 through the conveying channel 60.

[0096] The structure of the left degumming film unit 72 is the same as that of the right degumming film unit 73, and the degumming mode of the adhesive film 80 is the same, which is not described here.

[0097] Refer to Figure 14 , Figure 15 The upper degumming film unit 7 includes an upper fork 70, when it is needed to strip the adhesive film 80 wound on the film winding rod 3344 of the upper tearing assembly 41, the plurality of film winding rods 3344 of the upper tearing assembly 41 enter the slot of the upper fork 70, the second rotating jaw 41021 of the upper tearing assembly 41 is in the open state, the third telescopic unit 4101 of the upper tearing assembly 41 drives the second power unit 41022 to drive the second rotating jaw 41021 to rise, and the adhesive film 80 wound on the plurality of film winding rods 3344 of the upper tearing assembly 41 is stripped off under the action of the upper fork 70 and enters the material collecting trolley 6.

[0098] The structure of the lower adhesive film stripping unit 71 is the same as that of the upper adhesive film stripping unit 7, and the adhesive film 80 is the same, which is not described here.

[0099] Working principle of the present application:
