Description

Technical Field

[0001] This application relates to photovoltaic cell manufacturing technology, and more particularly to a tape laying device for the internal material strip of a photovoltaic cell. Background Technology

[0002] In the manufacturing process of photovoltaic cells, there is a process of laying material tapes. For example, after photovoltaic cells are wired together, they are arranged in a rectangular shape on the backsheet glass. Generally, film tape (material tape) is laid in the gaps between the rectangularly arranged cells. Another example is that busbars (material tape) are cut into a certain length and laid on the bending platform or in the photovoltaic module to be welded. Therefore, it is necessary to lay material tape of a certain length in a designated position. Manual laying of material tape is inefficient. Utility Model Content

[0003] In view of this, it is necessary to provide a tape-laying device that improves efficiency.

[0004] Some embodiments of this application provide a tape laying apparatus, which includes a feeding mechanism, a cutting mechanism, an adsorption member, a tape pulling mechanism, and a transfer mechanism. The feeding mechanism carries and releases the tape. The cutting mechanism is disposed on one side of the feeding mechanism and configured to allow the tape to pass through and cut the tape when it has passed a predetermined length. The adsorption member is opposite to the cutting mechanism and configured to provide an adsorption force to the tape. The tape pulling mechanism includes a tape pulling drive and a tape pulling member. The tape pulling drive drives the tape pulling member to the cutting mechanism. The tape pulling member is configured to fix or release the free end of the tape. The tape pulling drive drives the tape pulling member to move along a first direction to move the tape above the adsorption member. The transfer mechanism is configured to transfer the tape on the adsorption member to a predetermined position.

[0005] The aforementioned tape laying device pulls the tape through the cutting mechanism to the top of the adsorption unit via the tape pulling mechanism. The cutting mechanism cuts the tape, and the adsorption unit can adsorb the cut tape. The transfer mechanism takes the tape out of the adsorption unit and transfers it to the set position, thus realizing automated cutting and transfer of the tape to the set position, completing the automated laying of the tape and improving tape laying efficiency.

[0006] According to some embodiments of this application, a puller drives a strip of material of a predetermined length to protrude along a first direction to opposite sides of the adsorption member. The transfer mechanism includes a transfer drive and two transfer members, the transfer drive being configured to drive the two transfer members to move along a second direction to opposite sides of the adsorption member along the first direction, the second direction intersecting the first direction. The transfer members are configured to fix or release the ends of the strip along the first direction.

[0007] In the above embodiments, a strip of a set length protrudes along the first direction to the opposite sides of the adsorption member, forming two free ends at both ends of the strip that are not adsorbed by the adsorption member, which facilitates the transfer member to fix or release the free ends of the strip.

[0008] According to some embodiments of this application, the cutting mechanism and the adsorption element are spaced apart along a first direction to leave operating space; the tape laying device further includes a lifting mechanism, which includes a lifting drive and a carrier. The lifting drive is configured to drive the carrier to move up and down, so that the carrier moves into or out of the operating space. The carrier is configured to support the tape within the operating space.

[0009] In the above embodiments, the cutting mechanism and the adsorption component are spaced apart by an outflow operating space, allowing the transfer component to move into the operating space to clamp and fix the end of the material strip, thereby enabling subsequent transfer of the material strip to a set position. The pulling component drives the material strip, causing one end of the material strip to leave the cutting mechanism. When the material strip is made of a flexible material, when cutting or uncutting the material strip, the pulling component and the feeding mechanism pull the material strip simultaneously, allowing the material strip to be taut or slightly drooping. The longer the material strip passes through the cutting mechanism, the stronger the droop. The bearing component supports the material strip, reducing the risk of the material strip drooping and getting stuck at the end of the adsorption component, causing damage to the material strip.

[0010] According to some embodiments of this application, the lifting drive is configured to drive the carrier out of the operating space before the pull belt or transfer member moves into the operating space, and to exit the operating space when the pull belt or transfer member moves out of the operating space.

[0011] In the above embodiments, the lifting drive is configured to drive the carrier out of the operating space before the pull belt or transfer member moves into the operating space, and to exit the operating space when the pull belt or transfer member moves out of the operating space, thereby reducing the risk of interference between the carrier and the pull belt mechanism and the transfer mechanism.

[0012] According to some embodiments of this application, the carrier is provided with two first stops spaced apart along a second direction, allowing the material strip to pass between the two first stops. The adsorption member is provided with two second stops spaced apart along a second direction, allowing the material strip to pass between the two second stops.

[0013] In the above embodiment, two opposing first stop portions stop on opposite sides of the strip, which plays a positioning role for the strip. After the strip is cut, the portion of the strip away from the puller moves along the area between the two first stop portions, which helps to improve the positional accuracy of the strip entering the adsorption member.

[0014] According to some embodiments of this application, the transfer mechanism further includes two tensioning drive members, which are disposed on the transfer drive member. Each transfer member is disposed on the corresponding tensioning drive member. One of the two tensioning drive members drives the corresponding transfer member to move along a first direction, and the other of the two tensioning drive members drives the corresponding transfer member to move in the opposite direction of the first direction.

[0015] In the above embodiments, under the driving action of the two tensioning drive members, the two conveying members move in two opposite directions parallel to the first direction, so that the material belt conveyed by the conveying mechanism remains taut during the conveying process, which is beneficial to improving the positional accuracy of the material belt when it is moved to the set position.

[0016] According to some embodiments of this application, the belt puller is configured to drive the belt puller to move the belt sequentially along a first direction, move in the opposite direction of the first direction, and move along the first direction after the belt puller fixes the end of the belt. The cutting mechanism cuts the belt when the belt puller moves in the opposite direction of the first direction.

[0017] In the above embodiments, the puller drives the material belt to move in the opposite direction along the first direction, so that the uncut material belt is relaxed. The relaxed material belt will fall onto the adsorption member, and the adsorption member provides adsorption force to the material belt, thereby reducing the uncontrollable risk of the material belt moving freely due to sudden breakage after the cutting mechanism cuts the material belt, resulting in the end of the material belt moving away from the puller.

[0018] According to some embodiments of this application, the feeding mechanism includes a drum and a plurality of guide wheels. The drum is used to hold the wound strip and release the strip when it rotates. The plurality of guide wheels are spaced apart and rotatably disposed between the drum and the cutting mechanism, and are used to wind the strip to guide the strip from the drum to the cutting mechanism.

[0019] In the above embodiments, multiple guide wheels can temporarily store the material strip. The multiple guide wheels are spaced apart and tension the material strip, which helps to reduce the curvature of the material strip caused by the drum before the material strip is pulled, and helps to improve the uniform adsorption effect of the adsorption element on the material strip.

[0020] According to some embodiments of this application, the cutting mechanism includes a body and a clamping member and a cutting member disposed on the body. The body is configured to allow the strip to pass through and to support the strip. The clamping member is configured to clamp the strip onto the body as the strip passes through the body for a predetermined length. The cutting member is configured to cut the strip while the clamping member clamps the strip.

[0021] In the above embodiments, when the material strip passes through the main body at a set length, the pressing member presses down on the material strip, which is beneficial to the stability of the position of the free end of the material strip. In other words, it is beneficial to the stability of the starting position of the pulling member pulling the material strip at the cutting mechanism each time, which in turn helps to improve the positional accuracy of the pulling member driving the material strip onto the adsorption member.

[0022] According to some embodiments of this application, the pull belt member includes a clamping member and a release driving member, wherein the release driving member is disposed on the pull belt driving member and the clamping member is disposed on the release driving member.

[0023] The release drive can drive the clamp to move toward or away from the adsorption element, and the clamp is configured to clamp or release the end of the strip.

[0024] In the above embodiments, the release drive drives the belt pulling member to move away from the adsorption member, so that the free end of the belt moves away from the adsorption member. During the process of the belt pulling member moving the belt along the first direction, the belt is almost separated from the adsorption member before being cut, which reduces or avoids the friction between the belt and the adsorption member, and is conducive to improving the belt pulling efficiency.

Detailed Implementation

[0035] The implementation of this application will now be described with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0037] This application provides a tape laying apparatus in several embodiments, comprising a feeding mechanism, a cutting mechanism, an adsorption member, a tape pulling mechanism, and a transfer mechanism. The feeding mechanism carries and releases the tape. The cutting mechanism is located on one side of the feeding mechanism and is configured to allow the tape to pass through and cut the tape when it has passed a predetermined length. The adsorption member is opposite the cutting mechanism and is configured to provide an adsorption force to the tape. The tape pulling mechanism includes a pulling drive and a pulling member. The pulling drive drives the pulling member to the cutting mechanism. The pulling member is configured to fix or release the free end of the tape. The pulling drive drives the pulling member to move along a first direction to move the tape above the adsorption member, which extends along the first direction. The transfer mechanism is configured to transfer the tape on the adsorption member to a predetermined position.

[0038] The aforementioned tape laying device pulls the tape through the cutting mechanism to the top of the adsorption unit via the tape pulling mechanism. The cutting mechanism cuts the tape, and the adsorption unit can adsorb the cut tape. The transfer mechanism takes the tape out of the adsorption unit and transfers it to the set position, thus realizing automated cutting and transfer of the tape to the set position, completing the automated laying of the tape and improving tape laying efficiency.

[0039] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0040] Please see Figure 1 and Figure 2One embodiment of this application provides a tape laying device 100 for laying material tape 200 (e.g., Figure 7 (Or as shown in 8) to the set position. In one embodiment, the material strip 200 is a film strip, and the photovoltaic cells are arranged at intervals on a platform (e.g., back glass) after being string-welded. The material strip 200 is cut to a set length and laid in the gap between two adjacent cells.

[0041] The tape laying device 100 includes a feeding mechanism 10, a cutting mechanism 20, an adsorption element 30, a tape pulling mechanism 40, and a transfer mechanism 50. The feeding mechanism 10 is used to carry the uncut tape 200. The feeding mechanism 10 can also release the tape 200, allowing the tape 200 to pass through the cutting mechanism 20. The cutting mechanism 20 cuts the tape 200 when it has passed a predetermined length, to meet the requirement of laying tape 200 of a predetermined length.

[0042] The cutting mechanism 20 and the adsorption member 30 are arranged along the first direction X. The pulling mechanism 40 can fix the free end of the strip 200 protruding to one side of the cutting mechanism 20 after passing through the cutting mechanism 20, and drive the strip 200 to move along the first direction X above the adsorption member 30. The adsorption member 30 adsorbs the strip 200, which helps to stabilize the shape of the strip 200 of a set length. The transfer mechanism 50 is used to remove the strip 200 from the adsorption member 30 and transfer the strip 200 to a set position, such as transferring the strip 200 of a set length to the back glass between photovoltaic cells.

[0043] In one embodiment, the transfer mechanism 50 drives the material belt 200 to move along the second direction Y to a set position.

[0044] In one embodiment, the first direction X is perpendicular to the second direction Y, but this is not a limitation. For example, in other embodiments, the first direction X and the second direction Y may intersect at other angles, such as 60°, 45°, etc., as long as the material strip 200 moves along the first direction X to above the adsorption member 30, and the conveying mechanism 50 can pick up the two ends of the material strip 200 of a set length along the first direction X on the adsorption member 30, and convey the material strip 200 along the second direction Y to the set position.

[0045] Compared to the transfer mechanism 50 transferring the material belt 200 along the first direction X, the transfer mechanism 50 transferring the material belt 200 along the second direction Y is beneficial to improving work efficiency. Because the length of the material belt 200 (the dimension of the material belt 200 along the first direction X) is much greater than the width (the dimension of the material belt 200 along the second direction Y), it is beneficial to quickly move the material belt 200 out of the area above the adsorption member 30. It is also beneficial to avoid the space above the adsorption member 30 where the pulling mechanism 40 pulls the material belt 200. Thus, the transfer mechanism 50 transfers the cut material belt 200 to the set position and the pulling mechanism 40 pulls the material belt 200 to be cut to the top of the adsorption member 30 at the same time, which is beneficial to improving the work efficiency of the tape laying device 100.

[0046] The first direction X is perpendicular to the second direction Y. Compared with the first direction X and the second direction Y intersecting at other angles, the time taken for the conveying mechanism 50 to move the conveyor belt 200 above the adsorption member 30 is shorter, which further improves the working efficiency of the conveyor belt laying device 100.

[0047] It should be noted that in this application, the belt puller 41 drives the belt puller 43 to move along the first direction X, which means that the belt puller 41 can drive the belt puller 43 to move bidirectionally along the first direction X or in the opposite direction of the first direction X. When the belt puller 43 moves along the first direction X, it moves the material belt 200 above the adsorption member 30. When the belt puller 43 moves in the opposite direction of the first direction X, it can move the belt puller 43 to the cutting mechanism 20 to fix the free end of the material belt 200.

[0048] It is understood that in other embodiments, the transfer mechanism 50 may also transfer the conveyor belt 200 to a set position along the first direction X.

[0049] The cut length of the strip 200 is set according to actual needs, and this application does not limit it.

[0050] The tape laying device 100 pulls the tape 200, which has passed through the cutting mechanism 20, to the top of the adsorption member 30 via the tape pulling mechanism 40. The cutting mechanism 20 cuts the tape 200, and the adsorption member 30 can adsorb the cut tape 200. The transfer mechanism 50 takes the tape 200 out of the adsorption member 30 and transfers it to the set position, thus realizing the automated cutting and transfer of the tape 200 to the set position, completing the automated laying of the tape 200 and improving the tape laying efficiency.

[0051] The adsorption member 30 adsorbs and carries the material strip 200 of a set length. In cooperation with the transfer mechanism 50, it completes the process of transferring the material strip 200 to the set position. When the transfer mechanism 50 transfers the material strip 200, the pulling member 43 of the pulling mechanism 40 can move towards the cutting mechanism 20 to perform the next pulling operation, further improving the efficiency of the material strip 200.

[0052] The adsorption element 30 can adsorb the material strip 200, which helps to ensure the flatness of the material strip 200 and reduce the deformation of the material strip 200 during the transfer process. This reduces the impact of the deformation of the material strip 200 on the operation of the tape laying device 100 (e.g., removing the deformed material strip 200 or reshaping the material strip 200), thereby improving the efficiency of the tape laying device 100.

[0053] In one embodiment, the transfer mechanism 50 transfers the conveyor belt 200 by fixing both ends of the conveyor belt 200 along a first direction X. Please refer to [link to relevant documentation]. Figure 3 and Figure 4 The cutting mechanism 20 and the adsorption member 30 are spaced apart along the first direction X, forming an operating space 101 between them. The transfer mechanism 50 includes a transfer drive 51 and two transfer members 53. The two transfer members 53 are disposed on the transfer drive 51, and the transfer drive 51 drives the two transfer members 53 to move along the second direction Y.

[0054] It should be noted that the transfer drive 51 drives the two transfer members 53 to move along the second direction Y, which means that the transfer drive 51 can drive the two transfer members 53 to move bidirectionally along the second direction Y or the opposite direction of the second direction Y. The transfer members 53 can transfer the material belt 200 to the set position by moving along the second direction Y. The transfer members 53 can pick up the material belt 200 again by moving along the second direction Y.

[0055] In one embodiment, the puller 43 pulls the strip 200 along the first direction X until the strip 200 protrudes along the first direction X to opposite sides of the adsorption member 30. The adsorption member 30 provides adsorption force to the strip 200. The transfer drive 51 drives two transfer members 53 to move in opposite directions along the second direction Y to opposite sides of the adsorption member 30 along the first direction X. One of the two transfer members 53 moves into the operating space 101. The two transfer members 53 can fix the two ends of the strip 200 of a set length by clamping or adsorption. The transfer drive 51 drives the transfer members 53 to move along the second direction Y to move the strip 200 to the set position.

[0056] After the belt puller 43 pulls the belt 200 to a set length above the adsorption member 30, the belt puller 43 moves in the opposite direction of the first direction X to enter the next belt pulling operation.

[0057] The cutting mechanism 20 and the adsorption member 30 are spaced apart by the outflow operating space 101, so that the transfer member 53 can move into the operating space 101 to clamp and fix the end of the material belt 200, and then carry out the subsequent transfer of the material belt 200 to the set position.

[0058] It is understood that in other embodiments, the transfer member 53 can also strongly adsorb the material belt 200 to the side away from the adsorption member 30. For example, the adsorption force of the transfer member 53 on the material belt 200 is greater than the adsorption force of the adsorption member 30 on the material belt 200, or the adsorption member 30 stops adsorbing the material belt 200 when the transfer member 53 adsorbs the material belt 200, so that the transfer member 53 fixes the material belt 200 by adsorption, and realizes the subsequent transfer operation of the material belt 200. The operating space 101 can be omitted, and the cutting mechanism 20 and the adsorption member 30 do not need to be set apart.

[0059] In one embodiment, the tape laying device 100 further includes a lifting mechanism 60. The lifting mechanism 60 includes a lifting drive 61 and a support member 63. The lifting drive 61 is configured to drive the support member 63 to rise or fall in a direction parallel to a third direction Z, thereby moving the support member 63 into or out of the operating space 101. In one embodiment, the third direction Z is perpendicular to a first direction X and a second direction Y. The support member 63 is configured to support the tape 200 within the operating space 101.

[0060] When the belt puller 43 pulls the belt 200 from the cutting mechanism 20 through the operating space 101 and enters above the adsorption member 30, the lifting drive member 61 drives the carrier 63 to rise along the third direction Z into the operating space 101. The carrier 63 is roughly flush with the side of the adsorption member 30 facing the belt 200, and the carrier 63 can support the belt 200.

[0061] The puller 43 drives the strip 200, causing the free end of the strip 200 to leave the cutting mechanism 20. When the strip 200 is made of a flexible material, when cutting or uncutting the strip 200, the puller 43 and the feeding mechanism 10 pull the strip 200 simultaneously. The strip 200 can be taut or slightly drooping. The longer the strip 200 passes through the cutting mechanism 20, the stronger the droop. The support member 63 supports the strip 200, which can reduce the risk of the strip 200 being damaged by drooping and getting stuck at the end of the adsorption member 30.

[0062] It is understood that in other embodiments, when the operating space 101 is omitted, the lifting mechanism 60 may also be omitted.

[0063] It is understood that in other embodiments, the material strip 200 can also be a busbar. The busbar is more rigid than the membrane strip, and the degree of sagging of the busbar can be ignored when the belt puller 43 pulls the busbar to move along the first direction X, so the lifting mechanism 60 can also be omitted.

[0064] In one embodiment, please refer to Figure 4 and Figure 5The transfer mechanism 50 also includes two tensioning drive members 55. The two tensioning drive members 55 are disposed on the transfer drive member 51. Each transfer member 53 is disposed on its corresponding tensioning drive member 55. One of the two tensioning drive members 55 drives the corresponding transfer member 53 to move along a first direction X, and the other of the two tensioning drive members 55 drives the corresponding transfer member 53 to move in the opposite direction of the first direction X.

[0065] The transfer drive 51 drives two tension drive 55 and moves two transfer members 53 in opposite directions along the second direction Y, so that the two transfer members 53 are located on opposite sides of the adsorption member 30 along the first direction X. The two transfer members 53 clamp and fix the material belt 200 at opposite ends along the first direction X. The movement drive drives two tension drive 55 and moves two transfer members 53 along the second direction Y. The two tension drive 55 respectively drive the corresponding transfer members 53 to move in two opposite directions parallel to the first direction X, so that the material belt 200 is in a tensioned state, reducing the risk of the material belt 200 curling, warping, or misalignment when it moves to the set position.

[0066] Driven by the two tensioning drive members 55, the two transfer members 53 move in two opposite directions parallel to the first direction X, so that the material belt 200 transferred by the transfer mechanism 50 is kept taut during transfer, which helps to improve the positional accuracy of the material belt 200 when it is moved to the set position.

[0067] In one embodiment, please refer to Figure 6 The belt pull member 43 includes a clamping member and a release drive member 45. The release drive member 45 is disposed on the belt pull drive member 41, and the clamping member is disposed on the release drive member 45. The release drive member 45 is capable of driving the clamping member to move toward or away from the suction member 30, and the clamping member is configured to clamp or release the end of the belt 200.

[0068] The belt pull drive 41 drives the release drive 45 and moves the belt pull 43 in the opposite direction of the first direction X toward the cutting mechanism 20. The belt pull 43 fixes the free end of the material strip 200 at the cutting mechanism 20. Then, the release drive 45 drives the belt pull 43 to move in the third direction Z, so as to move the free end of the material strip 200 away from the carrier 63 and the adsorption member 30, so that the free end of the material strip 200 is separated from the adsorption member 30. The belt pull drive 41 drives the release drive 45 to move the belt pull 43 in the first direction X, so as to move the material strip 200 above the adsorption member 30. Next, the belt pull drive 41 drives the release drive 45 to move in the opposite direction of the first direction X. After the cutting mechanism 20 cuts the material strip 200, the belt pull drive 41 drives the release drive 45 to move in the first direction X until the belt pull 43 moves the material strip 200 to both sides of the adsorption member 30. The release drive 45 drives the belt pull 43 to move in the opposite direction of the third direction Z, so that the material strip 200 of the set length is adsorbed on the adsorption member 30.

[0069] The release drive 45 drives the pull belt 43 to rise along the third direction Z to move away from the adsorption element 30, so that the free end of the material belt 200 is away from the adsorption element 30. During the process of the pull belt 43 driving the material belt 200 to move along the first direction X, the material belt 200 is almost separated from the adsorption element 30 before being cut, which reduces or avoids the friction between the material belt 200 and the adsorption element 30, which is beneficial to improving the pulling efficiency.

[0070] It is understood that in other embodiments, the release drive member 45 may also be omitted. The material strip 200 is released by the pull member 43, and by controlling the distance between the pull member 43 and the adsorption member 30 to be less than a set value, when the pull member 43 releases the material strip 200, the adsorption member 30 adsorbs the material strip 200, causing the material strip 200 to adhere to the adsorption member 30.

[0071] In one embodiment, please refer to Figure 3 After the belt puller 43 fixes the free end of the material belt 200, the belt puller drive 41 is configured to drive the belt puller 43 to move the material belt 200 in the first direction X, in the opposite direction of the first direction X, and in the first direction X.

[0072] The cutting mechanism 20 cuts the material strip 200 when the belt puller 43 moves in the reverse direction of the first direction X. It should be noted that the cutting mechanism 20 performs the cutting operation on the material strip 200 while the belt puller 43 is moving the material strip 200 in the reverse direction of the first direction X, or when the belt puller 43 moves the material strip 200 in the reverse direction of the first direction X a certain distance and then pauses. After the cutting mechanism 20 cuts the material strip 200, the belt puller 43 moves the material strip 200 in the first direction X.

[0073] The puller 43 drives the material strip 200 to move in the opposite direction of the first direction X, so that the uncut material strip 200 is relaxed. The relaxed material strip 200 will fall onto the adsorption member 30. The adsorption member 30 provides adsorption force to the material strip 200. The puller 43 pulls the free end of the material strip 200 to move above the adsorption member 30. The part of the material strip 200 away from the puller 43 is adsorbed above the adsorption member 30 and moves along the adsorption member 30. This reduces the risk of uncontrollable position of the end of the material strip 200 away from the puller 43 due to the sudden break and free movement after the cutting mechanism 20 cuts the material strip 200.

[0074] To further improve the positional accuracy of the material strip 200 on the adsorption member 30, the carrier member 63 is provided with two first stop portions 631 spaced apart along the second direction Y, such as Figure 8 As shown, the material strip 200 is allowed to pass between the two first stop portions 631. In one embodiment, the first stop portion 631 includes a plurality of pillars arranged along a first direction X, but is not limited thereto. The two opposing first stop portions 631 stop on opposite sides of the material strip 200, providing positioning for the material strip 200. After the material strip 200 is cut, the portion of the material strip 200 away from the pulling member 43 moves along the area between the two first stop portions 631, which helps to improve the positional accuracy of the material strip 200 on the adsorption member 30.

[0075] The adsorption member 30 is provided with two second stop portions 31 spaced apart along the second direction Y, which allow the material strip 200 to pass through. In one embodiment, the second stop portion 31 is a protruding structure, but it is not limited thereto. The two opposing second stop portions 31 stop on opposite sides of the material strip 200, which plays a positioning role for the material strip 200. After the material strip 200 is cut, the portion of the material strip 200 away from the pull member 43 moves along the area between the two second stop portions 31, which helps to improve the positional accuracy of the material strip 200 entering the adsorption member 30.

[0076] In one embodiment, the belt puller 43 fixes the fixed end of the belt 200 by clamping the free end of the belt 200. The belt puller 43 is a clamping and fixing structure such as a gripper cylinder or a gripper electric cylinder.

[0077] To reduce the risk of interference between the carrier 63 and the belt pulling mechanism 40 and the transfer mechanism 50, the lifting drive 61 is configured to drive the carrier 63 out of the operating space 101 before the belt pulling mechanism 43 or the transfer mechanism 53 moves into the operating space 101, and to exit the operating space 101 when the belt pulling mechanism 43 or the transfer mechanism 53 moves out of the operating space 101.

[0078] It is understood that in other embodiments, the free end of the strip 200 can also be fixed in other ways. For example, when the free end of the strip 200 is provided with a hole, protrusion or other structure, the pull member 43 is provided with a structure that matches the hole, protrusion or other structure of the strip 200. For example, the hole of the strip 200 cooperates with the pin of the pull member 43, so that the pull member 43 can drive the strip 200 to move together.

[0079] Please see Figure 7 The cutting mechanism 20 includes a main body 21, a holding member 23, and a cutting member 25. The holding member 23 and the cutting member 25 are respectively disposed on the main body 21. The main body 21 is configured to allow the material strip 200 released from the feeding mechanism 10 to pass through and to support the material strip 200. The holding member 23 is configured to hold the material strip 200 against the main body 21 as the material strip 200 passes through a predetermined length of the main body 21. The cutting member 25 is configured to cut the material strip 200 when the holding member 23 holds the material strip 200.

[0080] When the strip 200 passes through the main body 21 to a set length, the holding member 23 presses down on the strip 200. The strip 200 is clamped and fixed by the holding member 23 and the main body 21. The cutting member 25 cuts the fixed strip 200, which helps to improve the accuracy of the cut strip 200 in reaching the set length and also helps to stabilize the position of the free end of the strip 200. In other words, it helps to stabilize the starting position of the pulling member 43 pulling the strip 200 at the cutting mechanism 20 each time, and thus helps to improve the positional accuracy of the pulling member 43 driving the strip 200 onto the adsorption member 30.

[0081] In one embodiment, please refer to Figure 8 The feeding mechanism 10 includes a drum 11 and multiple guide wheels 13. The drum 11 holds the wound strip 200. The strip 200 is released when the drum 11 rotates. The multiple guide wheels 13 are rotatably disposed between the drum 11 and the cutting mechanism 20. The multiple guide wheels 13 are located between the drum 11 and the main body 21. Each guide wheel 13 is used to wind the strip 200 to guide the strip 200 from the drum 11 to the main body 21 of the cutting mechanism 20. The multiple guide wheels 13 can temporarily store the strip 200, allowing the released strip 200 to directly enter the main body 21 for cutting, pulling, and conveying operations.

[0082] Multiple guide wheels 13 are spaced apart and tension the material belt 200, which helps to reduce the curvature of the material belt 200 caused by the drum 11 before the material belt is pulled, and helps to improve the uniform adsorption effect of the adsorption component 30 on the material belt 200.

[0083] The aforementioned tape laying device 100 pulls the tape 200, which has passed through the cutting mechanism 20, to the top of the adsorption member 30 via the tape pulling mechanism 40. The cutting mechanism 20 cuts the tape 200, and the adsorption member 30 can adsorb the cut tape 200. The transfer mechanism 50 takes the tape 200 out of the adsorption member 30 and transfers it to the set position, thereby realizing automated cutting and transfer of the tape 200 to the set position, completing the automated laying of the tape 200, and improving the tape laying efficiency.

[0084] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and substance of the technical solutions of this application.
