Description

Technical Field

[0001] The invention relates to the technical field of liquid crystal display panel manufacturing, and in particular to a glue pulling device. Background Art

[0002] ACF (Anisotropic Conductive Film) glue is mainly used in the liquid crystal display panel industry. There are tiny conductive particles inside the ACF glue. After the conductive particles are crushed, electrical conduction can be achieved between the driver circuit board and the display panel. The ACF tape is composed of a release film and ACF glue. During use, the ACF glue needs to be cut off but the release film must not be cut off. Then the ACF glue is attached to a specific position of the driver circuit board and then bound to the display panel, while the release film is collected as waste.

[0003] In the existing ACF attachment process, the ACF glue is mostly cut into the size required for product attachment, and then directly attached to the product. The problem with this operation is that the two adjacent sections of ACF glue cannot be guaranteed to be completely separated, that is, the two sections of ACF glue are still connected together by residual parts. Then, during attachment, there is still a risk that the latter section of ACF glue will be bonded together, resulting in attachment failure, which leads to a waste of resources. For this reason, a transition glue section can be cut out in the middle of each two adjacent sections of ACF glue, so that the two sections of ACF glue can be easily separated. After the transition glue section in the middle of the ACF glue is removed, the product can be smoothly glued without adhesion. However, the device for removing the transition glue section is generally inefficient, and the actuator is more complex, requiring a large installation space, and the application conditions are limited.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0037] The present invention provides a glue pulling device in certain embodiments, including a back support mechanism 10 and a glue pulling mechanism. The back support mechanism 10 is provided with a back support surface 15 for supporting the glue strip to be pulled, and the glue strip to be pulled is adhered with transition glue. The glue pulling mechanism includes a translation mechanism 20 and a glue pulling head 30, and the glue pulling head 30 is arranged on the translation mechanism 20. The translation mechanism 20 drives the glue pulling head 30 to move back and forth in the direction of approaching and moving away from the back support surface 15. When the translation mechanism 20 drives the glue pulling head 30 to approach the back support surface 15, the glue pulling head 30 can move to a position where it abuts against the glue strip to be pulled and the glue pulling head 30 is adhered to the transition glue on the glue strip to be pulled. When the translation mechanism 20 drives the glue pulling head 30 away from the back support surface 15, the glue pulling head 30 drives the transition glue to separate from the glue strip to be pulled.

[0038] Reference Figure 1 and Figure 4 The process of removing the transition glue of the present invention is as follows: first, the side of the tape to be removed with the transition glue is the sticky side, and the other side is the smooth side. When the operator places the tape to be removed on the back support surface 15, the smooth side of the tape to be removed contacts the back support surface 15, and the sticky side of the tape to be removed corresponds to the glue removal head 30.

[0039] Then the translation mechanism 20 is started, and the movement direction of the translation mechanism 20 is the direction close to or away from the glue strip to be pulled. The glue pulling head 30 provided on the translation mechanism 20 has a glue pulling surface 37 for sticking the transition glue, and the glue pulling surface 37 only corresponds to the transition glue. When the translation mechanism 20 drives the glue pulling head 30 to move in the direction close to the glue strip to be pulled until the glue pulling head 30 abuts against the glue strip to be pulled, the glue pulling surface 37 touches the transition glue and sticks to it. Then the translation mechanism drives the glue pulling head 30 and the transition glue sticking to the glue pulling head 30 to move in the direction away from the glue strip to be pulled until the transition glue is separated from the glue strip to be pulled.

[0040] In some embodiments, the direction in which the translation mechanism 20 drives the rubber pulling head 30 to approach and move away from the back support surface 15 is the Y-axis direction. Figure 2 The translation mechanism 20 includes a Y-axis substrate 21 and a Y-axis connecting plate 22. The Y-axis connecting plate 22 moves along the Y-axis direction relative to the Y-axis substrate 21, and the Y-axis substrate 21 is fixed relative to the back support surface 15; a glue pulling cylinder 210 is arranged on the side of the Y-axis substrate 21 away from the Y-axis connecting plate 22, and a cylinder push rod 211 is connected to the output end of the glue pulling cylinder 210. The cylinder push rod 211 moves along the Y-axis direction, and a displacement hole is opened on the Y-axis substrate 21; a driving block 220 is arranged on the side of the Y-axis connecting plate 22 close to the Y-axis substrate 21, and a side of the Y-axis connecting plate 22 away from the Y-axis substrate 21 is connected to the glue pulling head 30, and the driving block 220 is connected to the cylinder push rod 211 through the displacement hole, and the driving block 220 moves in the displacement hole when the cylinder push rod 211 is extended or retracted.

[0041] Reference Figure 2 , glue pulling cylinder 210 and cylinder push rod 211 are arranged on Y-axis base plate 21, and drive block 220 is arranged on Y-axis connecting plate 22, so that relative movement of Y-axis base plate 21 and Y-axis connecting plate 22 can be realized. Since fixed power source (i.e. glue pulling cylinder 210 and cylinder push rod 211) is arranged on one side of Y-axis base plate 21 to provide driving force, Y-axis connecting plate 22 is arranged on the other side to meet the movement of glue pulling head 30, so that translation mechanism 20 can not only meet the mobile demand, but also provide the driving force required for movement. This kind of design translation mechanism 20 is compact in structure, and forms a tightly connected whole, so that the glue pulling device as a whole is small and light, and saves space.

[0042] Furthermore, if Figure 2 As shown, a limit adjustment block 222 is provided on one side of the Y-axis connecting plate 22 close to the Y-axis substrate 21, and the limit adjustment block 222 is threadedly connected to the Y-axis connecting plate; the limit adjustment block 222 is spaced apart from the driving block 220 and the spacing direction is consistent with the moving direction of the rubber pulling head 30, and the limit adjustment block 222 is threadedly connected to the driving block 220 through a long screw.

[0043] When the driving block 220 is closer to the back support surface 15, the smaller the stroke of the driving block 220 driven by the glue pulling cylinder 210 is, the smaller the stroke distance between the glue pulling head 30 driven by the glue pulling cylinder 210 and the back support surface 15 is; conversely, the larger the distance between the driving block 220 and the back support surface 15 is, the larger the stroke of the driving block 220 driven by the glue pulling cylinder 210 is, and the larger the stroke distance between the glue pulling head 30 and the back support surface 15 is.

[0044] During the application of the glue pulling device, workers can rotate the long screw to change the distance between the driving block 220 and the limit adjustment block 222, and then complete the adjustment of the stroke distance between the glue pulling head 30 and the back support surface 15. The adjustment of the stroke distance can ensure that the driving block 220 generates a certain amount of overpressure under the fixed stroke of the glue pulling cylinder 210, and avoid deformation and breakage of the glue strip to be pulled due to excessive overpressure.

[0045] Furthermore, a return spring 223 is sleeved on the long screw rod. When the worker rotates the long screw rod to move the driving block 220 away from the limit adjustment block 220, the return spring 223 can provide a driving force, saving time and effort and improving work efficiency.

[0046] Furthermore, if Figure 2 As shown, a Y-guide rail 212 is provided on one side of the Y-axis substrate 21 close to the Y-axis connecting plate 22, and a sliding block 221 is provided on one side of the Y-axis connecting plate 22 close to the Y-axis substrate 21. The sliding block 221 is slidably matched with the Y-guide rail 212, and the sliding direction of the sliding block 221 and the Y-guide rail 212 is the Y-axis direction. The arrangement of the Y-guide rail 212 and the sliding block 221 can guide the movement of the Y-axis connecting plate 22, so that the movement of the Y-axis connecting plate 22 relative to the Y-axis substrate is smoother, thereby increasing the stability of the device operation.

[0047] In some embodiments, Figure 1 As shown, the glue pulling mechanism also includes a material wheel assembly 50. Figure 2 and Figure 3As shown, the material wheel assembly 50 includes a feeding wheel 52 and a receiving wheel 53, and the feeding wheel 52 and the receiving wheel 53 are located on one side of the Y-axis connecting plate 22 where the glue pulling head 30 is provided, and the feeding wheel 52 and the receiving wheel 53 are rotatably connected to the Y-axis connecting plate 22, and the adhesive paper tape 54 is wound around the feeding wheel 52, the glue pulling head 30 and the receiving wheel 53 in sequence; the viscosity between the adhesive paper tape 54 and the transition glue is greater than the viscosity between the transition glue and the glue tape to be pulled, when the Y-axis connecting plate 22 drives the glue pulling head 30 to abut against the back support surface 15, the adhesive surface of the adhesive paper tape 54 adheres to the transition glue, and the smooth surface of the adhesive paper tape 54 covers the glue pulling head 30, and when the Y-axis connecting plate 22 drives the glue pulling head 30 away from the back support surface 15, the adhesive paper tape 54 adheres to the transition glue and separates it from the glue tape to be pulled.

[0048] One end of the adhesive tape 54 is wound around the unwinding wheel 52, and the other end is wound around the receiving wheel 53, and a portion between the two ends of the adhesive tape 54 is covered on the adhesive pulling head 30. The smooth surface of the adhesive tape 54 abuts against the adhesive pulling surface 37, and the sticky surface of the adhesive tape 54 corresponds to the transition glue.

[0049] When the Y-axis connecting plate 22 drives the glue pulling head 30 to move in the direction close to the glue tape to be pulled, until the glue pulling surface 37 abuts against the glue tape to be pulled, the sticky surface of the adhesive paper tape 54 touches the transition glue and sticks to it. Since the stickiness between the sticky surface of the adhesive paper tape 54 and the transition glue is greater than the stickiness between the transition glue and the sticky surface of the glue tape to be pulled, when the Y-axis connecting plate 22 drives the glue pulling head 30 to move in the direction away from the glue tape to be pulled, the adhesive paper tape 54 sticks to the transition glue and separates it from the glue tape to be pulled.

[0050] After that, the material collection wheel 53 rotates, and the adhesive tape 54 with the transition glue is wound and recycled. The adhesive tape 54 pulls the material discharge wheel 52 to rotate during the process of being wound and recycled, and the material discharge wheel 52 discharges a section of the adhesive tape 54 that is not adhered to the transition glue. In the process of discharging and collecting materials, the part of the adhesive tape 54 wrapped on the glue pulling head 30 will also be replaced, so as to achieve the continuous and uninterrupted glue pulling action of the glue pulling head 30 until the roll of adhesive tape 54 is consumed. This design completes the recovery of the transition glue while the glue pulling operation, and realizes that one driving source completes multiple actions, the action connection is more closely connected, and the structure is more compact.

[0051] In some embodiments, Figure 1 As shown, the glue pulling mechanism also includes a clip mechanism 40. Figure 2As shown, the magazine mechanism 40 includes a magazine base plate 41, and the magazine base plate 41 is slidably matched with the Y-axis connecting plate 22 through a guide assembly, and the Y-axis connecting plate 22 drives the magazine base plate 41 to move along the Y-axis direction, and the side of the magazine base plate 41 away from the Y-axis connecting plate 22 is tightly connected to the rubber pulling head 30, and the unloading wheel 52 and the collecting wheel 53 are both rotatably connected to the magazine base plate 41.

[0052] The unloading wheel 52 and the collecting wheel 53 are both arranged on the magazine base plate 41, and the magazine base plate 41 is detachably connected to the Y-axis connecting plate 22, that is, the magazine mechanism 40 as a whole is detachable from the translation mechanism 20. Therefore, when the adhesive tape 54 in the unloading wheel 52 is consumed or the collecting wheel 53 cannot recycle the adhesive tape 54, the magazine base plate 41 can be directly removed from the Y-axis connecting plate 22, which means that the magazine mechanism 40 is separated from the translation mechanism 20. Then, a new magazine base plate 41 is installed with the Y-axis connecting plate 22. The new magazine base plate 41 has an empty collecting wheel 52 and a unloading wheel 52 with a full roll of adhesive tape 54 installed. After the replacement, the translation mechanism 20 can be directly started to continue the glue pulling operation. Then, the removed magazine mechanism 40 is replaced with offline adhesive tape. By detachably connecting the clip mechanism 40 to the translation mechanism 20 , the adhesive tape 54 can be quickly replaced, which reduces the downtime of the entire device due to replacement of the adhesive tape 54 , thereby improving the utilization rate of the entire device.

[0053] In some embodiments, a positioning device 70 is further provided on the magazine base plate 41, and the positioning device 70 is used to position the magazine base plate 41 and the Y-axis connecting plate 22 when they are connected to each other. The positioning device can be a reset type indexing pin, a self-locking type indexing pin, a handle type indexing pin, a flange type indexing pin or a compact type indexing pin.

[0054] Specifically, when the positioning device adopts a self-locking indexing pin, the self-locking indexing pin includes a pin body, a pin head, a handle and a built-in spring. The built-in spring is sleeved on the pin body, and the pin body passes through the magazine base plate 41. A pin head is provided at one end of the pin body close to the Y-axis connecting plate 22, and a handle is provided at one end of the pin body away from the Y-axis connecting plate 22. A matching portion corresponding to the pin head is provided on the Y-axis connecting plate 22.

[0055] When the magazine base plate 41 is separated from the Y-axis connecting plate 22, the pin head is in a retracted state and the handle is in a pulled-out state. After the worker installs the magazine base plate 41 on the Y-axis connecting plate 22 through the guide assembly, the worker rotates the pulled-out handle and releases the handle after rotating it to a certain angle. The pin head returns to a protruding state through the elastic force of the built-in spring and completes the matching with the matching part, thereby achieving the positioning between the magazine base plate 41 and the Y-axis connecting plate 22.

[0056] Furthermore, a fastening device is provided between the magazine base plate 41 and the Y-axis connecting plate 22. The fastening device may be a quick clamp. When the magazine base plate 41 is connected to the Y-axis connecting plate 22 and positioned by the self-locking indexing pin, the worker presses the handle of the quick clamp to complete the compression of the magazine base plate 41 and the fixation to the Y-axis connecting plate 22.

[0057] In some embodiments, the guide assembly includes a fixed guide block 224 and a movable guide block 410, the number of the fixed guide blocks 224 and the movable guide blocks 410 are both two, the two fixed guide blocks 224 are spaced apart on the side of the Y-axis connecting plate 22 close to the magazine base plate 41, a connecting groove is formed between the two fixed guide blocks 224, and the two movable guide blocks 410 are spaced apart on the side of the magazine base plate 41 close to the Y-axis connecting plate 22 and can be embedded in or out of the connecting groove along the sliding direction; when the movable guide block 410 is embedded in the connecting groove, the relative position of the magazine mechanism 40 and the translation mechanism 20 in the Y-axis direction is fixed, and when the movable guide block 410 is out of the connecting groove, the magazine mechanism 40 is separated from the translation mechanism 20, and the embedding and separation direction of the movable guide block 410 is the Z-axis direction, and the Z-axis direction is perpendicular to the Y-axis direction.

[0058] The clip base plate 41 and the Y-axis connecting plate 22 are disassembled by plugging and unplugging through the cooperation between the fixed guide block 224 and the movable guide block 410. This design has a simple structure and low production cost, and can realize the rapid installation and disassembly between the clip base plate 41 and the Y-axis connecting plate 22, saving time and thus improving the operating efficiency of the device.

[0059] In some embodiments, a sensor is provided on the Y-axis connecting plate 22, and the output end of the sensor passes through the clip bottom plate 41 to sense the adhesive tape 54 on the discharge wheel 52. A brake 411 is provided on the clip bottom plate 41, and the output shaft of the brake 411 passes through the clip bottom plate 41 and is rotatably connected to the discharge wheel 52.

[0060] The sensor is used to monitor the use of the adhesive tape 54 on the unloading wheel 52. When the sensor detects that the adhesive tape 54 has been used up, it sends a signal to the display device to remind the staff to perform the material change operation. The setting of the brake 411 can provide a certain rotation damping to the unloading wheel 52 when it rotates. The setting of the brake can not only prevent the pulling speed from being too fast when supplying the pulling material, resulting in an overshoot of the rotation speed of the unloading wheel 52, but also prevent the supply of too many blank adhesive tapes 54, resulting in a waste of resources. The setting of the brake can also increase the tension of the adhesive tape 54 between the unloading wheel 52 and the collecting wheel 53, making the process of unloading and collecting more smooth, thereby improving the glue pulling effect and efficiency.

[0061] In some embodiments, Figure 2As shown, the clip mechanism 40 further includes a reset swing arm 42 and a rotating device. The reset swing arm 42 is located on the side of the clip base plate 41 away from the receiving wheel 53. A limit position is provided on the side of the reset swing arm 42 close to the Y-axis base plate 21. The limit position is eccentric to the connecting shaft 430. A limit device is provided between the limit position and the Y-axis base plate 21. The limit device is used to limit the reset swing arm 42 from moving together with the clip base plate 41.

[0062] like Figure 3 As shown, the rotating device includes a connecting shaft 430, a first one-way bearing 432 and a second one-way bearing 433. The first one-way bearing 432 is arranged on the magazine base plate 41, and the second one-way bearing 433 is arranged in the reset swing arm 42. The connecting shaft 430 is rotatably connected with the second one-way bearing 433, the first one-way bearing 432 and the receiving wheel 53 in sequence. The direction in which the first one-way bearing 432 and the second one-way bearing 433 drive the connecting shaft 430 to rotate is a first turn, and the direction opposite to the first turn is a second turn.

[0063] When the magazine base plate 41 is close to the back support surface 15, the reset swing arm 42 rotates along the second direction, and the connecting shaft 430 is stationary relative to the magazine base plate 41. When the magazine base plate 41 is away from the back support surface 15, the reset swing arm 42 drives the first one-way bearing 432, the second one-way bearing 433 and the connecting shaft 430 to rotate along the first direction, and the receiving wheel 53 winds the adhesive tape 54 to complete the receiving.

[0064] Reference Figure 3 , a bearing seat 431 is provided on the clip base plate 41, a first one-way bearing 432 is provided in the bearing seat 431, the inner rings of the first one-way bearing 432 and the second one-way bearing 433 can only rotate in the first direction relative to the outer ring, and the outer rings can only rotate in the second direction relative to the inner ring. In this embodiment, the first direction is defined as the clockwise rotation direction, and the second direction opposite to the first direction is the counterclockwise rotation direction. Since the inner rings of the first one-way bearing 432 and the second one-way bearing 433 are both fixedly connected to the connecting shaft 430, the outer ring of the first one-way bearing 432 is fixedly connected to the clip base plate 41, and the outer ring of the second one-way bearing 433 is fixedly connected to the reset swing arm 42. Therefore, the inner rings of the connecting shaft 430, the first one-way bearing 432 and the second one-way bearing 433 can only rotate clockwise relative to the reset swing arm 42, and the reset swing arm 42 rotates counterclockwise relative to the connecting shaft 430.

[0065] Further, the specific process of the reset swing arm 42 cooperating with the rotating device is as follows: first, when the glue pulling cylinder 210 extends, the Y-axis connecting plate 22 will move in the Y-axis direction close to the glue strip to be pulled under the guidance of the Y-guide rail 212. Because the clip base plate 41 is connected to the Y-axis connecting plate 22, the glue pulling head 30, the reset swing arm 42, the connecting shaft 430, the first one-way bearing 432 and the second one-way bearing 433 arranged on the clip base plate 41 move in the Y-axis direction along with the Y-axis connecting plate 22. However, since the reset swing arm 42 is provided with a limiting position, the Y-axis base plate 21 is provided with a limiting device, under the cooperation of the limiting position and the limiting device, when the glue pulling cylinder 210 extends, the reset swing arm 42 is driven to rotate counterclockwise around the connecting shaft 430, while the connecting shaft 430, the first one-way bearing 432 and the second one-way bearing 433 are stationary relative to the clip base plate 41, and the receiving wheel 53 rotatably connected to the connecting shaft 430 also does not rotate.

[0066] Then, the Y-axis connecting plate 22 moves until the adhesive tape 54 coated on the adhesive pulling head 30 is pressed and contacted with the transition glue and adheres. When the adhesive pulling cylinder 210 retracts, contrary to the above description, the Y-axis connecting plate 22 will move along the Y-axis direction away from the adhesive tape to be pulled under the guidance of the Y-guide rail 212. The adhesive tape 54 coated on the adhesive pulling head 30 removes the transition glue from the adhesive tape to be pulled by adhesion, thereby completing the adhesive pulling operation.

[0067] At the same time, during the retraction of the glue pulling cylinder 210, the reset swing arm 42 will be driven to rotate clockwise around the connecting shaft 430, so the reset swing arm 42 drives the connecting shaft 430 to rotate clockwise together, so the material receiving wheel 53 connected to the connecting shaft 430 also rotates clockwise. When the material receiving wheel 53 rotates, it pulls the adhesive paper material wrapped around itself to perform a winding action to rotate around itself, thereby completing the material receiving. Similarly, due to the movement of the adhesive paper material belt 54, the material discharging wheel 52 will also be pulled to perform the material discharging action. Then the glue pulling cylinder 210 extends and retracts again to complete the glue pulling operation until the adhesive paper material belt 54 on the material discharging wheel 52 is consumed.

[0068] Specifically, since the extension and retraction strokes of the glue pulling cylinder 210 are fixed values, and the distance between the center of the limit position set on the reset swing arm 42 and the center of the connecting shaft 430 is fixed, the angle of each counterclockwise rotation of the reset swing arm 42 relative to the connecting shaft 430 is consistent, and the consistent rotation angle will result in a fixed rotation angle of the connecting shaft 430. Then, the rotation angle of the receiving wheel 53 driven by the connecting shaft 430 during the glue pulling process is also a fixed value, thereby realizing the fixed-length supply of the adhesive tape 54 on the unloading wheel 52.

[0069] The arrangement of the reset swing arm 42 and the rotating device enables the device to realize the linkage operation of the glue pulling operation and the fixed-length supply of the adhesive paper material belt 54 through a single power source, which can effectively shorten the connection time interval between the dynamic glue pulling actions and improve the operation efficiency.

[0070] In some embodiments, Figure 3 As shown, the rotating device further includes a deep groove ball bearing 434, which is disposed in the bearing seat 431 and is rotatably connected to the connecting shaft 430. The deep groove ball bearing 434 is used to axially limit the connecting shaft 430 and the bearing seat 431 to prevent the connecting shaft 430 from axially moving during operation, thereby ensuring the stability of the device operation.

[0071] In some embodiments, Figure 2 As shown, the limiting device includes a limiting block 420 and a pin 421. The limiting block 420 is fixedly connected to the Y-axis substrate 21. A limiting groove 422 is provided on the limiting block 420. One end of the pin 421 is located in the limiting position, and the other end of the pin 421 is located in the limiting groove 422.

[0072] When the magazine base plate 41 drives the reset swing arm 42 to move back and forth in the Y-axis direction, the pin shaft 421 can only rotate in the limiting groove 422 to limit the reset swing arm 42; when the magazine base plate 41 drives the reset swing arm 42 to move back and forth in the Z-axis direction, the pin shaft 421 can be restricted in the limiting groove 422.

[0073] When the magazine base plate 41 drives the reset swing arm 42 to move along the Y-axis direction close to the glue strip to be pulled out, the pin shaft 421 is located in the limiting groove 422, so that the reset swing arm 42 cannot move along with the magazine base plate 41 as a whole. Therefore, the pin shaft 421 cooperates with the limiting block 420 to limit the movement of the reset swing arm 42 in the Y-axis direction.

[0074] In some embodiments, the clip mechanism 40 further includes a reset spring 43 and a stop block 44, one end of the reset spring 43 is connected to the reset swing arm 42, and the other end of the reset spring 43 is connected to the clip bottom plate 41, when the reset swing arm 42 rotates along the second turning direction, the reset spring 43 is stretched and deformed, and when the reset swing arm 42 rotates along the first turning direction, the reset spring 43 returns to its original state according to its own elasticity;

[0075] The stop block 44 is connected to the magazine base plate 41 , and when the magazine mechanism 40 is disengaged from the translation mechanism 20 , the stop block 44 can limit the rotation of the reset swing arm 42 along the first turning direction.

[0076] When the reset swing arm 42 moves in the Y-axis direction away from the glue strip to be pulled, the reset spring 43 uses its own elastic force to quickly reset the reset swing arm 42. When the clip mechanism 40 is removed from the translation mechanism 20, the reset swing arm 42 can be effectively prevented from rotating under the action of the reset spring 43, thereby affecting the stability of the glue pulling device.

[0077] In some embodiments, Figure 5 As shown, the back support mechanism 10 is provided with an adsorption hole 14, which is formed on the back support surface 15, and the adsorption hole 14 is used to adsorb the glue tape to be pulled out. The setting of the adsorption hole 14 can ensure that when the glue pulling head 30 removes excessive glue, it exerts a pulling force on the transition glue. When the adhesive paper tape 54 coated on the glue pulling head 30 is adhered to the transition glue, the adsorption force of the adsorption hole 14 on the glue tape to be pulled out can prevent the glue pulling head 30 from pulling it, resulting in the glue tape to be pulled out being unable to be attached after it sticks to each other.

[0078] In some embodiments, the back-support mechanism 10 can adjust its position and angle in the Y-axis direction and the X-axis direction relative to the glue tape to be pulled (the Y-axis direction is the direction approaching or moving away from the glue tape to be pulled, and the X-axis direction is perpendicular to the Y-axis direction) so that the back-support mechanism 10 and the glue tape to be pulled are more closely fitted, thereby better achieving the glue pulling operation.

[0079] Specifically, refer to Figure 5 The back support mechanism 10 also includes a back support plate 11, a back support connecting plate 13 and a back support fixing plate 12. The back support plate 11 is connected to the back support fixing plate 12 via the back support connecting plate 13. The back support plate 11 is provided with the back support surface 15.

[0080] The back support fixing plate 12 can move back and forth along the Y-axis direction relative to the glue strip to be pulled. When there is a gap between the back support support surface 15 and the glue strip to be pulled and no support force can be given to the glue strip to be pulled, the back support fixing plate 12 is adjusted to drive the back support support surface 15 on the back support support plate 11 to gradually approach the glue strip to be pulled along the Y-axis direction, so that the two are completely fitted, thereby improving the success rate of glue pulling.

[0081] The back support connecting plate 13 is movably assembled with the back support fixing plate 12, and the back support connecting plate 13 moves back and forth along the X-axis direction on the back support connecting plate 13 relative to the adhesive tape to be pulled. When the back support surface 15 and the adhesive tape to be pulled are misaligned and cannot be completely fitted, the back support connecting plate 13 is adjusted to move along the X-axis direction until the back support surface 15 on the back support plate 11 is completely fitted with the adhesive tape to be pulled, providing support force for the adhesive tape to be pulled, thereby improving the success rate of glue pulling.

[0082] The back support plate 11 is rotatably connected to the back support connecting plate 13, and the axial direction of the rotation axis of the back support plate 11 and the back support connecting plate 13 is parallel to the X-axis direction. The rotatable connection between the back support plate 11 and the back support connecting plate 13 can adjust the angle between the back support plate 11 and the adhesive tape to be pulled out, so that the back support surface 15 and the transition adhesive are more closely fitted.

[0083] In some embodiments, Figure 6 As shown, the rubber pulling head 30 includes a rubber pulling head body 32 and a connecting block 31. The connecting block 31 is provided with a plurality of disassembly connection positions, which are arranged at intervals along the Z-axis direction. The connecting block 31 is detachably connected to the magazine base plate 41 through the disassembly connection positions, and the rubber pulling head body 32 and the connecting block 31 are rotatably connected. When the connecting block 31 and the magazine base plate 41 are installed, the operator can determine a disassembly connection position at a suitable position according to the approximate position of the back support mechanism 10, and then fix the connecting block 31 and the magazine base plate 41 through the disassembly connection position. This arrangement can make a preliminary adjustment to the relative position of the rubber pulling head body 32 and the back support mechanism 10, thereby improving the rubber pulling accuracy.

[0084] In some embodiments, the glue pulling head body 32 has the function of rotating and adjusting around the Z axis, and the axial direction of the Z axis is perpendicular to the X axis direction and the Y axis direction. This setting can adjust the glue pulling head 30 and the transition glue level on the glue strip to be pulled adsorbed on the backing mechanism 10, thereby improving the success rate of glue pulling.

[0085] Specifically, refer to Figure 6 The rubber pulling head 30 also includes an adjusting pin 33, and the connecting block 31 includes a first protrusion 35 and a second protrusion 36. The adjusting pin 33 sequentially penetrates the first protrusion 35, the rubber pulling head body 32 and the second protrusion 36 along the Z-axis direction. The first protrusion 35 is provided with a top screw hole for installing an adjusting top screw 34, and the adjusting top screw 34 penetrates the first protrusion 35 and abuts against the rubber pulling head body 32. The second protrusion 36 is provided with a screw hole for installing a fixing screw, and the fixing screw is used to fix the adjusting pin 33 to prevent it from loosening and falling off.

[0086] The setting of the adjustment pin 33 and the adjustment top screw 34 can realize the rotation adjustment function of the glue pulling head body 32 around the Z axis. The setting of the adjustment top screw 34 can not only limit the rotation of the glue pulling head body 32, but also realize the rotation adjustment of the glue pulling head body 32 more linearly, and realize the quantification of the adjustment angle to a certain extent, so that the adhesion position between the glue pulling head body 32 and the transition glue can be made more accurate, and the adhesion between the two is higher, thereby improving the glue pulling accuracy and efficiency.
