Description

Technical Field

[0001] The present invention relates to the technical field of perovskite solar cell manufacturing, and particularly to an automatic taping device. Background Art

[0002] In the field of perovskite solar cell manufacturing, the taping and encapsulation process is one of the core processes, and its encapsulation accuracy directly determines the product yield and performance. In order to improve the taping efficiency and accuracy, automatic taping equipment is mainly used for automatic taping at present. During the taping process of the automatic taping equipment, it is necessary to ensure that the tape is smoothly conveyed at a constant tension to ensure that the adhesive layer has a uniform thickness, no bubbles, no wrinkles, and the fitting position error can be accurately controlled.

[0003] However, existing taping equipment usually uses traditional mechanical or open-loop control systems, which have the disadvantages of low taping accuracy, complex mechanisms, high assembly costs, and large floor space after machine matching. In the future, it is necessary to further develop automatic taping equipment with low cost, high accuracy, and adapted to the characteristics of perovskite solar cells to achieve commercial applications. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic taping device to ensure uniform taping, no bubbles, no wrinkles, etc., and improve the taping efficiency and effect.

[0005] The purpose of the present invention is achieved by the following technical solutions:

[0006] The present invention provides an automatic taping device, including: a first carrier plate, a tape unwinding mechanism, a tape winding mechanism, and a taping mechanism fixed on the first carrier plate. The taping mechanism is used to receive the tape output by the tape unwinding mechanism and attach the tape to the carrier to be taped, and the tape winding mechanism is used to recover the release paper separated from the tape.

[0007] The taping mechanism includes a first matching part. One side of the first matching part forms a guiding surface in contact with the tape, and the other side of the first matching part is connected to an elastic element. The elastic element can be deformed under pressure and apply an elastic force towards the carrier to be taped to the first matching part, so that the guiding surface presses the tape tightly against the carrier to be taped.

[0008] As a further improvement of an embodiment of the present invention, the width of the guiding surface is greater than or equal to the width of the tape; and / or, the tape pasting mechanism further includes a second cooperating portion, the first cooperating portion is slidably connected to the second cooperating portion in the direction of the elastic force. In the initial state, the guiding surface of the first cooperating portion protrudes from the second cooperating portion in the direction towards the carrier to be pasted with tape; when the guiding surface contacts the carrier to be pasted with tape, the guiding surface is squeezed by the carrier to be pasted with tape to be flush with the second cooperating portion, and the first cooperating portion squeezes the elastic element. The beneficial effects are as follows: By utilizing the mutual cooperation among the first cooperating portion, the elastic element and the second cooperating portion, while ensuring that the tape is evenly pressed and pasted onto the carrier to be pasted with tape, it can also prevent the glue layer from slipping on the surface of the carrier to be pasted with tape (such as the surface of a smooth glass substrate) during the pasting process, reducing the fitting error; in addition, setting the width of the guiding surface to be greater than or equal to the width of the tape can enable the tape to be squeezed by the guiding surface in the width direction, further improving the pasting effect.

[0009] As a further improvement of an embodiment of the present invention, continuous sliding grooves are formed on the mutually facing sides of the first cooperating portion and the second cooperating portion. The sliding grooves on the mutually facing surfaces of the first cooperating portion and the second cooperating portion are perpendicular to the surface of the carrier to be pasted with tape, and the sliding grooves are used for transporting the tape or the release paper;

[0010] and / or, the tape pasting mechanism further includes a third cooperating portion fixedly connected to the second cooperating portion, and the third cooperating portion abuts against one end of the elastic element away from the first cooperating portion;

[0011] and / or, on the side of the first cooperating portion close to recovering the release paper, and on the side of the second cooperating portion close to transporting the tape.

[0012] As a further improvement of an embodiment of the present invention, the automatic tape pasting device further includes a telescopic cylinder, the telescopic cylinder is connected to the first carrier plate, and the telescopic cylinder drives the first carrier plate to move up and down, so that the first cooperating portion presses the tape against the carrier to be pasted with tape or separates the first cooperating portion from the carrier to be pasted with tape;

[0013] and / or, the automatic tape pasting device further includes a hollow rotating platform and a first closed-loop servo motor for providing a rotational driving force to the hollow rotating platform. The hollow rotating platform is connected to the tape pasting mechanism, so that the first closed-loop servo motor can drive the tape pasting mechanism to rotate through the hollow rotating platform.

[0014] As a further improvement of an embodiment of the present invention, the automatic adhesive pasting device further includes a buffer device disposed below the telescopic cylinder. The buffer device is configured to apply an upward buffering force to the first carrier plate when the telescopic cylinder controls the first carrier plate to drive the first engaging portion to move downward. The beneficial effect is that by providing a buffer device below the telescopic cylinder, it can be avoided that when the telescopic cylinder drives the first engaging portion to move downward, the impact force on the carrier to be pasted is too large when the lead-out surface of the first engaging portion just contacts the carrier to be pasted, thereby avoiding mechanical damage to the carrier to be pasted when pressing and pasting the adhesive, and improving the smoothness and reliability of the operation of the adhesive pasting device.

[0015] And / or, the automatic adhesive pasting device further includes a second carrier plate, which is used to integrate the telescopic cylinder, the buffer device, the hollow rotary platform, and the first closed-loop servo motor. The beneficial effect is that in the present invention, the first carrier plate is used to integrate components such as the unwinding mechanism, the winding mechanism, and the adhesive pasting mechanism, and the second carrier plate is used to integrate components such as the telescopic cylinder and the hollow rotary platform. By connecting the telescopic cylinder to the first carrier plate to fix the relative positions between the first carrier plate, the components on the first carrier plate, the second carrier plate, and the components on the second carrier plate, the relative position relationship and connection relationship between the components can be reasonably set, so that the automatic adhesive pasting device of the present invention has the characteristics of simple structure, high integration, small volume, etc., and has a high degree of fit with the placement platform of the carrier to be pasted.

[0016] As a further improvement of an embodiment of the present invention, the automatic adhesive pasting device further includes a cylinder cutting device fixed on the first carrier plate. The cylinder cutting device is close to the adhesive pasting mechanism and is disposed on one side of transporting the tape, and is used to provide a pneumatic impact in the direction of the tape so that the tape on the tape is cut off and the release paper remains integral.

[0017] As a further improvement of an embodiment of the present invention, the unwinding mechanism includes an unwinding reel. A unwinding roller is disposed in the middle of the unwinding reel. A first rotating shaft is provided at the center of the unwinding roller. The unwinding reel is fixed on the first carrier plate through the first rotating shaft. The tape is spirally wound around the outer peripheral surface of the unwinding roller.

[0018] The unwinding mechanism further includes a tension control device, which is configured to apply a resistance when the tape is separated from the unwinding mechanism to provide a tension force to the tape.

[0019] The winding mechanism includes a winding reel. A winding roller is disposed in the middle of the winding reel. A second rotating shaft is provided at the center of the winding roller. The winding reel is fixed on the first carrier plate through the second rotating shaft. The recovered release paper is spirally wound around the outer peripheral surface of the winding roller.

[0020] The winding mechanism further includes a coupling and a second closed-loop servo motor disposed on a side of the winding reel away from the winding roller. The coupling is fixedly connected to the second rotating shaft, and the second closed-loop servo motor is connected to the winding reel through the coupling, and is configured to apply a driving force to the winding reel to cause the winding reel to rotate around the second rotating shaft to wind the release paper, and drive the unwinding reel to rotate around the first rotating shaft to transport the tape.

[0021] As a further improvement of an embodiment of the present invention, the tension control device is disposed on a side of the first carrier plate away from the unwinding reel, and the tension control device is fixedly disposed on the first rotating shaft and connected to the unwinding reel through the first rotating shaft;

[0022] And / or, the unwinding mechanism further includes a fixing device connecting the unwinding reel and the first rotating shaft, and the fixing device is configured to fix the position of the unwinding reel on the first rotating shaft.

[0023] As a further improvement of an embodiment of the present invention, the automatic tape sticking device further includes a first guide wheel group and a second guide wheel group fixed on the first carrier plate. The first guide wheel group is disposed on a path where the tape is transported from the unwinding mechanism to the tape sticking mechanism, and is configured to allow the tape transported from the unwinding mechanism to enter from an inlet end of the chute. The second guide wheel group is disposed on a path where the release paper is recycled and transported from the tape sticking mechanism to the winding mechanism, and is configured to guide the release paper out along an outlet end of the chute and transport it to the winding mechanism.

[0024] As a further improvement of an embodiment of the present invention, the automatic tape sticking device further includes a cylinder clamping device fixed on the first carrier plate. The cylinder clamping device is disposed on a path of the recycled release paper, and is configured to apply a clamping force to the release paper passing through the cylinder clamping device.

[0025] Compared with the prior art, the beneficial effects of the present invention at least include: through the cooperation of the first engaging portion and the elastic element, the present invention can achieve a stable pressing force on the tape during the tape sticking process with a simple structure, and "coat" the tape on the carrier to be tape-stuck by pressing, so as to ensure that the tape is stably attached to the carrier to be tape-stuck. Compared with the prior art of manual tape sticking or using a roller to stick the tape, the tape sticking property of the present application on the carrier to be tape-stuck is stronger, and the tape attached to the carrier to be tape-stuck is not likely to have problems such as bubbles and wrinkles, and at the same time, it will not affect the tape sticking effect due to the movement inertia of the tape assembly during transportation.

Detailed implementation manners

[0033] Now, example embodiments will be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this invention will be more complete and comprehensive, and will fully convey the concept of the example embodiments to those skilled in the art. Like reference numerals in the figures denote the same or similar structures, and thus their repeated description will be omitted.

[0034] The words expressing positions and directions described in the present invention are all illustrated with reference to the accompanying drawings as examples, but can be changed according to needs, and all changes made are included within the protection scope of the present invention.

[0035] As Figures 1 to 4As shown, this embodiment provides an automatic glue sticking device, including a first carrier plate 21 and an unwinding mechanism 3 , a rewinding mechanism 4 and a glue sticking mechanism 5 fixed on the first carrier plate 21 .

[0036] The unwinding mechanism 3 is used to place the tape 1, which includes a release paper 11 and an adhesive layer 12 pasted on the release paper 11. The release paper 11 is attached to the sticky surface of the adhesive layer 12 to isolate the adhesive layer 12 from the external environment and prevent the adhesive layer 12 from sticking when not in use. At the same time, the adhesive layer 12 can be easily removed from the release paper 11 when needed.

[0037] Specifically, the adhesive tape 1 is a butyl adhesive tape, the isolation paper 11 is a release paper, and the adhesive layer 12 is a butyl rubber adhesive layer.

[0038] The gluing mechanism 5 is used to receive the adhesive tape 1 output by the unwinding mechanism 3, separate the adhesive layer 12 in the adhesive tape 1 from the release paper 11 and apply the adhesive layer 12 in the adhesive tape 1 to the carrier A to be glued, and the reeling mechanism 4 is used to recover the release paper 11 separated from the adhesive tape 1. Specifically, in the horizontal direction of the automatic gluing device, the unwinding mechanism 3 can be arranged on the right side of the entire device, the reeling mechanism 4 can be arranged on the left side of the entire device, and the gluing mechanism 5 is arranged between the unwinding mechanism 3 and the reeling mechanism 4; in the longitudinal direction of the automatic gluing device, the gluing mechanism 5 is arranged below the unwinding mechanism 3 and the reeling mechanism 4, the unwinding mechanism 3 can be arranged above the reeling mechanism 4, and of course, the unwinding mechanism 3 can also be arranged below the reeling mechanism 4.

[0039] See also Figure 5 and Figure 6 The adhesive laminating mechanism 5 comprises a first matching portion 51, one side of which forms a lead-out surface 511 that abuts against the adhesive tape 1, that is, the side of the first matching portion 51 facing the carrier A to be glued is the lead-out surface 511, and the lead-out surface 511 is used to laminarize the adhesive tape 1 onto the carrier A to be glued. The other side of the first matching portion 51 is connected to an elastic element 54, that is, the side of the first matching portion 51 that is away from the lead-out surface 511 is connected to the elastic element 54, and the elastic element 54 can be deformed under pressure and exert an elastic force on the first matching portion 51 toward the carrier A to be glued, so that the lead-out surface 511 presses the adhesive layer 12 in the adhesive tape 1 onto the carrier A to be glued.

[0040] The carrier A to be glued can be a glass substrate or other substrates or underlays to be glued, and the present invention is not limited thereto. During the gluing operation, the glue layer 12 at the front end of the adhesive tape 1 is separated from the release paper 11, and the separated glue layer 12 is pressed by the first matching portion 51 and adhered to the carrier A to be glued, and the release paper 11 can be pulled by the reeling mechanism 4 and recovered by the reeling mechanism 4. As the unwinding mechanism 3 continues to feed the adhesive tape 1, the reeling mechanism 4 continues to pull the release paper 11 so that the release paper 11 is separated from the glue layer 12.

[0041] The glue - applying mechanism 5 further includes a second engaging portion 52. The first engaging portion 51 and the second engaging portion 52 are slidably connected in the direction of the elastic force. In the initial state, the guiding surface 511 of the first engaging portion 51 protrudes from the second engaging portion 52 in the direction towards the carrier A to be glued. When the guiding surface 511 contacts the carrier A to be glued, the guiding surface 511 is squeezed by the carrier A to be flush with the second engaging portion 52, and the first engaging portion 51 squeezes the elastic element 54. That is to say, when the guiding surface 511 and the carrier A to be glued approach each other under an external force and the guiding surface 511 contacts the carrier A to be glued, the external force will further cause the guiding surface 511 and the carrier A to be glued to be closely attached. At this time, the carrier A to be glued will squeeze the guiding surface 511, causing the first engaging portion 51 to move upward relative to the second engaging portion 52 until the guiding surface 511 is flush with the lower surface of the second engaging portion 52. Since the elastic element 54 is arranged above the first engaging portion 51, during the process of the first engaging portion 51 moving upward relative to the second engaging portion 52, the first engaging portion 51 compresses the elastic element 54 upward. The elastic element 54 is squeezed and deformed, thereby applying an elastic force towards the surface of the carrier A to be glued to the first engaging portion 51, so that the glue layer 12 located on the guiding surface 511 can be tightly pressed and adhered to the carrier A to be glued. In this way, compared with the prior art of manual glue - applying or using a roller to apply glue, in this application, by the mutual cooperation of the first engaging portion 51 and the elastic element 54 in the glue - applying mechanism 5, in the process of the tape 1 being transported, the glue layer 12 located on the guiding surface 511 can be tightly pressed and evenly adhered to the carrier A to be glued by pressing, preventing the glue layer 12 from slipping on the surface of the carrier A to be glued (such as the surface of a smooth glass substrate) during the glue - applying process, and reducing the fitting error.

[0042] Wherein, the width of the guiding surface 511 is greater than or equal to the width of the tape 1, so that the glue layer 12 in the tape 1 can be squeezed by the guiding surface 511 in the width direction.

[0043] Furthermore, the glue - applying mechanism 5 further includes a third engaging portion 53 fixedly connected to the second engaging portion 52. The third engaging portion 53 abuts against one end of the elastic element 54 away from the first engaging portion 51. Specifically, the third engaging portion 53 is arranged above the first engaging portion 51 and the second engaging portion 52 and is fixedly connected to at least the second engaging portion 52, and the third engaging portion 53 is perpendicular to the second engaging portion 52. The elastic element 54 is arranged between the first engaging portion 51 and the third engaging portion 53 and connects the first engaging portion 51 and the third engaging portion 53.

[0044] Of course, a connecting portion 512 may be provided on the side of the first engaging portion 51 away from the lead-out surface 511. The connecting portion 512 can be used to connect the first engaging portion 51 and the third engaging portion 53. A through-hole is also provided at the corresponding position of the third engaging portion 53 corresponding to the connecting portion 512. The connecting portion 512 can pass through the through-hole and extend out of the side surface of the third engaging portion 53 away from the first engaging portion 51. Specifically, the connecting portion 512 can be a cylindrical structure. The elastic element 54 can be wound around the connecting portion 512, and the upper end surface of the elastic element 54 is connected to the third engaging portion 53, and the lower end surface of the elastic element 54 is connected to the first engaging portion 51. For example, the elastic element 54 is a spring, and the spring is sleeved on the connecting portion 512.

[0045] The size of the through-hole on the third engaging portion 53 can be slightly larger than the size of the connecting portion 512 and smaller than the size of the upper end surface of the elastic element 54. So that when the lead-out surface 511 contacts the carrier A to be adhesively attached and the first engaging portion 51 moves upward relative to the second engaging portion 52, the connecting portion 512 can move upward through the through-hole of the third engaging portion 53, while the upper end surface of the elastic element 54 is abutted against the lower surface of the third engaging portion 53. The first engaging portion 51 moves upward to compress the elastic element 54, and the elastic element 54 is squeezed and applies a downward elastic force to the first engaging portion 51, so that the lead-out surface 511 presses the adhesive layer 12 tightly against the carrier A to be adhesively attached.

[0046] See Figure 1 , on the side of the first engaging portion 51 close to the recovery release paper 11, and on the side of the second engaging portion 52 close to the transport tape 1. That is to say, on the side of the first engaging portion 51 close to the winding mechanism 4, and on the side of the second engaging portion 52 close to the unwinding mechanism 3. Of course, it can also be that the first engaging portion 51 is on the side close to the unwinding mechanism 3, and the second engaging portion 52 is on the side close to the winding mechanism 4.

[0047] Combined with Figure 5 and Figure 6 , continuous sliding grooves are provided on the mutually facing side surfaces of the first engaging portion 51 and the second engaging portion 52. The sliding grooves on the mutually facing surfaces of the first engaging portion 51 and the second engaging portion 52 are perpendicular to the surface of the carrier A to be adhesively attached. The sliding grooves are used for transporting the transport tape 1 or the release paper 11. Specifically, taking the side of the first engaging portion 51 close to the winding mechanism 4 and the side of the second engaging portion 52 close to the unwinding mechanism 3 as an example, the sliding groove 521 of the second engaging portion 52 is used for transporting the transport tape 1. The release paper 11 is close to the surface of the sliding groove 521 of the second engaging portion 52. When the tape 1 passes through the lead-out surface 511 of the first engaging portion 51, the adhesive layer 12 is pressed by the lead-out surface 511 and adhered to the carrier A to be adhesively attached and separated from the release paper 11. The separated release paper 11 then passes through the sliding groove 513 of the first engaging portion 51 and is transported by the sliding groove 513 of the first engaging portion 51 to the winding mechanism 4.

[0048] See Figure 3 andFigure 4 The automatic glue pasting device further includes a telescopic air cylinder 6. The telescopic air cylinder 6 is connected to the first carrier plate 21. The telescopic air cylinder 6 drives the first carrier plate 21 to move up and down, so that the first matching part 51 presses the glue layer 12 against the carrier A to be glued or separates the first matching part 51 from the carrier A to be glued. That is, the first matching part 51 can press the carrier A to be glued through the driving force of the telescopic air cylinder 6 and squeeze the elastic element 54. Specifically, the telescopic air cylinder 6 includes a piston rod 61, which is connected to the first carrier plate 21 through a connecting piece 23. The connecting piece 23 is fixed at the position of the piston rod 61 of the telescopic air cylinder 6. When the telescopic air cylinder 6 is started, its piston rod stretches up and down to drive the connecting piece 23 and the first carrier plate 21 to move up and down at the same time.

[0049] The automatic glue pasting device may further include a buffer device 62 disposed below the telescopic air cylinder 6, specifically, it may be disposed below the piston rod 61 of the telescopic air cylinder 6. The buffer device 62 is used to apply an upward buffer force to the first carrier plate 21 when the telescopic air cylinder 6 controls the first carrier plate 21 to drive the first matching part 51 to move downward, so as to avoid excessive impact force on the carrier A to be glued when the lead-out surface 511 of the first matching part 51 just contacts the carrier A to be glued when the telescopic air cylinder 6 drives the first matching part 51 to move downward, avoid mechanical damage to the carrier A to be glued when pressing and pasting glue, and improve the smoothness and reliability of the operation of the glue pasting device.

[0050] The buffer device 62 may be a device with elastic function, such as a spring or a rubber pad, etc., or a damping device or a buffer cavity, etc. The present invention does not limit this, as long as it is ensured that the buffer device 62 is connected to the piston rod 61, and when the piston rod 61 makes a telescopic movement, the acting force of the piston rod 61 moving downward can be slowed down.

[0051] Of course, a telescopic air cylinder 6 with a built-in buffer cavity can also be provided, that is, a buffer cavity is provided at the lower end of the telescopic air cylinder 6. When the piston rod 61 of the telescopic air cylinder 6 approaches the end, the gas in the closed buffer cavity is compressed to generate back pressure to slow down the piston speed.

[0052] Further, the automatic glue pasting device further includes a hollow rotating platform 71 and a first closed-loop servo electrode 72 for providing a rotational driving force to the hollow rotating platform 71. The hollow rotating platform 71 is connected to the glue pasting mechanism 5, so that the first closed-loop servo electrode 72 can drive the glue pasting mechanism 5 to rotate through the hollow rotating platform 71. That is to say, when it is necessary to change the glue pasting direction of the glue pasting mechanism 5 on the surface of the carrier A to be glued, the first closed-loop servo electrode 72 can be used to control the hollow rotating platform 71 to change the rotation of the glue pasting mechanism 5. For example, the hollow rotating platform 71 can control the glue pasting mechanism 5 to paste glue along the length direction of the carrier A to be glued. When the glue pasting mechanism 5 completes the glue pasting along the length direction of the carrier A to be glued, the glue pasting mechanism 5 can be controlled to rotate 90° to paste glue along the width direction of the carrier A to be glued.

[0053] Furthermore, the automatic glue sticking device may further include a second carrier plate 22 , and the second carrier plate 22 is used to integrate the telescopic cylinder 6 , the buffer device 62 , the hollow rotating platform 71 and the first closed-loop servo electrode 72 .

[0054] Continue to see Figure 3 and Figure 4 , the second carrier plate 22 is arranged on the side of the first carrier plate 21 away from the glue sticking mechanism 5, the hollow rotating platform 71 and the first closed-loop servo electrode 72 can be fixedly arranged in the upper area of ​​the second carrier plate 22, and the telescopic cylinder 6 is fixedly connected to the side of the second carrier plate 22 away from the first carrier plate 21 and is located below the hollow rotating platform 71 and the first closed-loop servo electrode 72. The second carrier plate 22 is also provided with an opening 221 in the area near the piston rod 61 of the telescopic cylinder 6, and the connecting member 23 connecting the piston rod 61 and the first carrier plate 21 is located at the opening 221. One end of the buffer device 62 is connected to the piston rod 61, and the other end is connected to the second carrier plate 22. When the telescopic cylinder 6 is turned on and the piston rod 61 starts to telescope, the connecting member 23 can move up and down at the opening 221 of the second carrier plate 22 to drive the first carrier plate 21 to move up and down.

[0055] It should be noted that the present invention does not limit the size of the opening 221 on the second carrier plate 22. It only needs to ensure that the connecting member 23 does not interfere with the second carrier plate 22 when the piston rod 61 of the telescopic cylinder 6 performs telescopic movement, thereby ensuring the stability of the first matching portion 51 in the glue laminating mechanism 5 when pressing the glue layer 12.

[0056] Combination Figure 1 and Figure 2 The automatic glue sticking device further includes a cylinder cutting device 81 fixed on the first carrier plate 21. The cylinder cutting device 81 is close to the glue sticking mechanism 5 and is arranged on one side of the transport tape 1, and is used to provide air pressure shock in the direction of the tape 1 so that the glue layer 12 on the tape 1 is cut off and the isolation paper 11 is kept as a whole. Specifically, the cylinder cutting device 81 is arranged on one side of the second matching portion 52, that is, the side of the cylinder cutting device 81 providing air pressure shock faces the slide groove 521 of the second matching portion 52, and cuts the glue layer 12 located at the corresponding position of the slide groove 521 of the second matching portion 52.

[0057] Specifically, the cylinder cutting device 81 is a blade cylinder cutting device, which is provided with a blade at one end of the slide groove 521 of the second matching part 52. The blade applies pressure to the tape 1 at the corresponding position of the slide groove 521 of the second matching part 52 under the push of the air pressure impact provided by the cylinder. The pressure applied by the cylinder to the blade can be controlled so that only the adhesive layer 12 on the tape 1 is cut off, thereby reducing the cutting force on the isolation paper 11 and retaining the continuity of the isolation paper 11, so that the isolation paper 11 can be smoothly recycled to the winding mechanism 4.

[0058] See also Figures 1 to 4 The unwinding mechanism 3 includes an unwinding material disc 31, a unwinding roller 32 is provided in the middle of the unwinding material disc 31, a first rotating shaft 33 is provided at the center of the unwinding roller 32, the unwinding material disc 31 is fixed to the first carrier plate 21 through the first rotating shaft 33, and the adhesive tape 1 is spirally wound around the outer peripheral surface of the unwinding roller 32. The unwinding material disc 31 and the unwinding roller 32 can be integrally formed, and can rotate around the first rotating shaft 33 at the same time to drive the adhesive tape 1 to rotate. The winding mechanism 4 includes a winding material disc 41, a winding roller 42 is provided in the middle of the winding material disc 41, a second rotating shaft 43 is provided at the center of the winding roller 42, the winding material disc 41 is fixed to the first carrier plate 21 through the second rotating shaft 43, and the recycled release paper 11 is spirally wound around the outer peripheral surface of the winding roller 42. The winding material disc 41 and the winding roller 42 can be integrally formed, and can rotate around the second rotating shaft 43 at the same time. The winding mechanism 4 also includes a coupling 44 and a second closed-loop servo motor 45 arranged on the side of the winding material tray 41 away from the winding roller 42. The coupling 44 is fixedly connected to the second rotating shaft 43. The second closed-loop servo motor 45 is connected to the winding material tray 41 through the coupling 44, and is used to apply a driving force to the winding material tray 41 so that the winding material tray 41 and the winding roller 42 rotate around the second rotating shaft 43 to recycle the isolation paper 12, and drive the unwinding material tray 31 and the unwinding roller 32 to rotate around the first rotating shaft 33 to transport the tape 1.

[0059] Furthermore, the unwinding mechanism 3 also includes a tension control device 34, which is used to apply resistance when the adhesive tape 1 is separated from the unwinding mechanism 3, so as to provide tension to the adhesive tape 1. Specifically, the tension control device 34 is arranged on the side of the first carrier plate 21 away from the unwinding material tray 31, and the tension control device 34 is fixedly arranged on the first rotating shaft 33 and connected to the unwinding material tray 31 through the first rotating shaft 33, so as to control the rotation speed and braking torque of the unwinding material tray 31 and the unwinding roller 32, so as to keep the tension of the adhesive tape 1 in the unwinding mechanism 3 stable. For example, when the second closed-loop servo motor 45 controls the winding material tray 41 to stop rotating, the adhesive tape 1 in the unwinding mechanism 3 may continue to rotate due to inertia, and the tension control device 34 will detect the tension signal of the adhesive tape 1 in real time, and automatically adjust the output torque according to the tension signal of the adhesive tape 1, so as to keep the tension of the adhesive tape 1 stable during transportation.

[0060] Specifically, the tension control device 34 is a magnetic powder brake. Of course, the tension of the tape 1 can also be controlled by setting a servo motor and a tension sensor. For example, the tension sensor detects the tension signal of the tape 1 in real time, feeds the tension signal back to the system controller, and the system controller dynamically adjusts the speed or torque of the servo motor according to the received tension signal to achieve constant tension of the tape 1.

[0061] The unwinding mechanism 3 further includes a fixing device 35 connecting the unwinding reel 31 and the first rotating shaft 33. The fixing device 35 is used to fix the position of the unwinding reel 31 on the first rotating shaft 33 and lock the unwinding reel 31 to prevent problems such as the tape 1 breaking due to slipping and loosening during rotation.

[0062] Specifically, in this embodiment, there are two unwinding reels 31. Both ends of the unwinding roller 32 are respectively connected to an unwinding reel 31. The fixing device 35 is arranged on the side of the unwinding reel 31 away from the first carrier plate 21. By arranging two unwinding reels 31 and winding the tape 1 around the unwinding roller 32 between the two unwinding reels 31, the tape 1 can be transported more stably and fixed.

[0063] See Figure 1 , the automatic gluing device further includes a first guide wheel group 91 and a second guide wheel group 92 fixed on the first carrier plate 21. The first guide wheel group 91 is arranged on the path where the tape 1 is transported from the unwinding mechanism 3 to the gluing mechanism 5, and is used to guide the tape 1 transported from the unwinding mechanism 3 to enter through the inlet end of the chute. The second guide wheel group 92 is arranged on the path where the release paper 11 is recycled and transported from the gluing mechanism 5 to the winding mechanism 4, and is used to guide the release paper 11 out along the outlet end of the chute and transport it to the winding mechanism 4. Specifically, the inlet end of the chute is the upper port of the chute 521 of the second matching part 52, and the outlet end of the chute is the upper port of the chute 513 of the first matching part 51. The first guide wheel group 91 includes at least two guide wheels, and the second guide wheel group 92 includes at least two guide wheels.

[0064] The present invention does not limit the number of guide wheels of the first guide wheel group 91 and the second guide wheel group 92 and the specific setting positions of the guide wheels. It only needs to ensure that the guide wheel on the side of the first guide wheel group 91 close to the second matching part 52 can vertically guide the tape 1 into the inlet of the chute (i.e., the upper port of the chute 521 of the second matching part 52), and the guide wheel on the side of the second guide wheel group 92 close to the first matching part 51 can continue to vertically guide the release paper 11 at the outlet of the chute (i.e., the chute 513 of the first matching part 51) to ensure that the tape 1 or the release paper 11 can be tightly attached to the chutes on the first matching part 51 and the second matching part 52 during transportation through the gluing mechanism 5.

[0065] Furthermore, the automatic gluing device further includes a cylinder clamping device 82 fixed on the first carrier plate 21. The cylinder clamping device 82 is arranged on the path of the recycled release paper 11 and is used to apply a clamping force to the release paper 11 passing through the cylinder clamping device 82 to clamp the release paper 11 and prevent phenomena such as slack or stacking during the recycling of the release paper 11, ensuring the stability of the recycling process of the release paper 11. The cylinder clamping device 82 can be arranged at the position between the two guide wheels of the second guide wheel group 92 to apply a clamping force to the release paper 11 on the transportation path between the two guide wheels.

[0066] The present invention integrates components such as an unwinding mechanism 3, a winding mechanism 4, and a tape pasting mechanism 5 on a first carrier plate 21, and integrates components such as a telescopic cylinder 6 and a hollow rotating platform 71 on a second carrier plate 22. By reasonably setting the relative position and connection relationships between the components, the automatic tape pasting device of the present invention has the characteristics of simple structure, high integration, and small volume. Its dimensions in the horizontal and vertical directions can be about 200 mm × 700 mm, with a high degree of fit with the placement platform of the carrier A to be pasted with tape. At the same time, the transmission path of the tape 1 is short, avoiding unstable factors (such as slack of the tape 1 or the separator paper 11) during the transmission process with too long a transmission path.

[0067] The working principle of the automatic tape pasting device of the present invention is as follows: Control the telescopic cylinder 6 to drive the first carrier plate 21 to move downward, so as to drive the first mating part 51 on the tape pasting mechanism 5 to move downward. The lead-out surface 511 at the lower end of the first mating part 51 abuts against the surface of the carrier A to be pasted with tape and moves upward relative to the second mating part 52 until the lead-out surface 511 is flush with the lower end surface of the second mating part 52. At this time, since the elastic element 54 at the upper end of the first mating part 51 is compressed under pressure, an elastic force is applied to the first mating part 51 downward, and the lead-out surface 511 presses down the tape 1 so that the adhesive layer 12 is tightly attached to the surface of the carrier A to be pasted with tape; Control the winding reel 41 and the separator paper 11 to rotate through the second closed-loop servo motor 45 to drive the unwinding reel 31 and the tape 1 to rotate. At the same time, the placement platform of the carrier A to be pasted with tape can be controlled to start moving to drive the carrier A to be pasted with tape to move, and start pasting the tape. During the pasting process, the lead-out surface 511 always applies a downward pressing force to the adhesive layer 12, and evenly pastes the adhesive layer 12 on the carrier A to be pasted with tape; When the pasting is almost completed, according to the preset pasting length, control the opening of the cylinder cutting device 81 to cut the adhesive layer 12 outside the tape 1 at the corresponding position on the chute 521 of the second mating part 52, so that the cut adhesive layer 12 just passes through the lead-out surface 511 and is tightly attached to the end of the position on the carrier A to be pasted with tape that needs to be pasted; Control the telescopic cylinder 6 to drive the first carrier plate 21 to move upward, so as to drive the tape pasting mechanism 5 to move upward away from the carrier A to be pasted with tape. At this time, due to the elastic force of the elastic element, the first mating part 51 moves downward relative to the second mating part 52, and the tape pasting mechanism 5 returns to the initial state; The tape pasting is completed.

[0068] Of course, during the pasting process, the tension control device 34, the fixing device 35, the buffer device 62, and the cylinder clamping device 82 are always kept in the open state. After completing the pasting of one step, if it is necessary to change the pasting direction, the first closed-loop servo motor 72 can be controlled to start to drive the hollow rotating platform 71 to drive the tape pasting mechanism 5 to rotate, and then the pasting operation can be carried out.

[0069] In summary, through the mutual cooperation of the components on the tape sticking mechanism, the present invention "applies" the tape to the carrier to be taped by pressing. Compared with the prior art methods of manual tape sticking or using rollers to stick tape, the adhesion of the tape applied to the carrier to be taped in this application is stronger, and the tape adhered to the carrier to be taped is not prone to problems such as bubbles and wrinkles. At the same time, it will not affect the tape sticking effect due to the movement inertia of the tape assembly during transportation, preventing the tape from slipping on the surface of the carrier to be taped during the tape sticking process and reducing the fitting error. In addition, the automatic tape sticking device in this application has the characteristics of simple device structure, high integration, small volume, etc. The transmission path of the tape assembly is short, improving the transmission efficiency, and the device is convenient for maintenance and installation and has low cost.

Without departing from the principles and purposes of the present invention, those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the invention, and all such changes should fall within the protection scope of the claims of the present invention.
