Description

Technical Field

[0001] This application relates to the field of mechanical equipment technology, and in particular to a release film recycling device. Background Technology

[0002] Currently, in order to protect the components of electronic devices, many components are covered with release films before assembly. When assembling the above products, the release films need to be peeled off.

[0003] In existing technologies, manually peeling the release film off the workpiece is time-consuming; or, using a recycling device to remove the release film from the workpiece with tape, the tape is prone to loosening and falling off or sticking together, causing the device to malfunction, affecting work efficiency, wasting tape, and hindering cost reduction. Summary of the Invention

[0004] This application provides a release film recycling device that keeps the tape taut throughout the entire collection process, ensuring consistent tension before and after collection. This makes the device operate more smoothly, prevents the tape from falling off or sticking together due to loosening, and improves work efficiency.

[0005] This application provides a release film recycling device, which includes at least one adhesive tape, a mounting plate, and a feeding mechanism and a receiving mechanism spaced apart on the mounting plate. A first end of the adhesive tape is connected to the feeding mechanism, which stores unused sections of the adhesive tape. A second end of the adhesive tape is connected to the receiving mechanism, which recycles sections of the adhesive tape to which the release film is attached. The release film recycling device further includes at least one actuator located between the feeding mechanism and the receiving mechanism. A portion of the tape is wound around at least one actuator, and the actuator is movable between a first position and a second position, the second position being away from the workpiece on which the release film is disposed relative to the first position; wherein, in the first position, the adhesive side of the tape wound on the working surface of the actuator is able to contact the release film on the workpiece so as to adhere the release film when the actuator moves toward the second position; and, the positions of the two ends of the tape located between the feeding mechanism and the receiving mechanism remain unchanged when the actuator moves between the first position and the second position.

[0006] In the release film recycling device of this application embodiment, since a portion of the tape between the feeding mechanism and the receiving mechanism is wrapped around the actuator, when the actuator moves between the first position and the second position, the positions of both ends of the tape between the feeding mechanism and the receiving mechanism remain unchanged. This causes the feeding mechanism, such as the feeding wheel, and the receiving mechanism, such as the receiving wheel, to remain stationary. Throughout the receiving process, the tape can be kept taut, ensuring consistent receiving tension. The tape runs more smoothly, preventing the tape from falling off or sticking together due to loosening, thus improving work efficiency and preventing tape waste, which helps reduce costs.

[0007] In one possible implementation, the actuator includes: a support plate; a support block disposed at one end of the support plate near the workpiece along the direction of movement; and a steering wheel rotatably disposed on the support plate between the feeding mechanism and the support block, and located away from the workpiece relative to the support block, with the steering wheel and the support block offset from each other; wherein the tape is sequentially arranged around the steering wheel and the support block, with the adhesive surface of the tape on the steering wheel facing the steering wheel, and the adhesive surface of the tape on the support block facing away from the support block, and the surface of the support block facing the workpiece being the working surface; and, when the actuator moves between the first position and the second position, the tape moves around the steering wheel and the support block, and the length change of the tape between the feeding mechanism and the support block is opposite to the length change of the tape between the support block and the receiving mechanism, such that the positions of the two ends of the tape between the feeding mechanism and the receiving mechanism remain unchanged. In other words, in this implementation, when the actuator moves from the first position to the second position, the length of the conveyor belt between the feeding mechanism and the steering wheel increases, and the length of the conveyor belt between the support block and the receiving mechanism decreases, so that the positions of both ends of the conveyor belt between the feeding mechanism and the receiving mechanism remain unchanged; when the actuator moves from the second position to the first position, the length of the conveyor belt between the feeding mechanism and the steering wheel decreases, and the length of the conveyor belt between the support block and the receiving mechanism increases, so that the positions of both ends of the conveyor belt between the feeding mechanism and the receiving mechanism remain unchanged.

[0008] In one possible implementation, the release film recycling device further includes: a first guide wheel, disposed on the mounting plate on the side of the actuator near the feeding mechanism, and closer to the workpiece relative to the steering wheel when the actuator is in the first position; a second guide wheel, disposed on the mounting plate on the other side of the actuator near the receiving mechanism, and farther away from the workpiece relative to the steering wheel when the actuator is in the second position; wherein, the tape without the release film wrapped around the first guide wheel, with the adhesive side of the tape on the first guide wheel facing outward; the tape with the release film wrapped around the second guide wheel, with the adhesive side of the tape on the second guide wheel facing inward; and the tape between the first guide wheel and the steering wheel, the tape between the steering wheel and the support block, and the tape between the support block and the second guide wheel extend along the moving direction of the actuator, such that: when the actuator moves between the first position and the second position, the change in length of the tape between the first guide wheel and the steering wheel is opposite to the change in length of the tape between the support block and the second guide wheel, thereby keeping the positions of both ends of the tape between the feeding mechanism and the receiving mechanism unchanged. In other words, in this implementation, in order to ensure that the length change rate of the conveyor belt between the feeding mechanism and the support block is the same as the length change rate of the conveyor belt between the support block and the receiving mechanism, a first guide wheel can be provided on the side of the steering wheel near the feeding mechanism so that the conveyor belt between the first guide wheel and the steering wheel extends along the moving direction of the actuator. A second guide wheel can be provided on the side of the steering wheel near the receiving mechanism so that the conveyor belt between the support block and the second guide wheel extends along the moving direction of the actuator. In addition, the conveyor belt between the steering wheel and the support block also extends along the moving direction of the actuator.

[0009] In one possible implementation, the steering wheel includes a first shaft and a first cylinder, the first shaft being disposed on the mounting plate, and the first cylinder being rotatably disposed on the first shaft; or, the steering wheel includes a plurality of first branches spaced apart in a circumferential direction, each first branch including a second shaft and a second cylinder, the second shaft being disposed on the mounting plate, and the second cylinder being rotatably disposed on the second shaft. That is, in this implementation, the steering wheel may include only one first shaft and one first cylinder, with the first cylinder rotatably disposed on the first shaft, resulting in a simple structure that is convenient for manufacturing and installation; alternatively, the steering wheel may include multiple second shafts, each with a second cylinder rotatably disposed on it, thereby reducing the contact area between the steering wheel and the conveyor belt, making the conveyor belt movement smoother.

[0010] In one possible implementation, the steering wheel includes a plurality of second branches spaced apart in a circumferential direction. Each second branch includes a third shaft and a plurality of balls. The third shaft is disposed on the mounting plate, and the plurality of balls are rotatably disposed on the third shaft. That is, in this implementation, the steering wheel may include a plurality of third shafts, each with a plurality of balls rotatably disposed thereon. This reduces the contact area between the steering wheel and the conveyor belt, resulting in smoother belt movement.

[0011] In one possible implementation, the portion of the outer circumferential surface of the steering wheel that contacts the adhesive tape is provided with an anti-stick material; and / or, the outer circumferential surface of the steering wheel is provided with multiple grooves or perforated structures. That is, in this implementation, to reduce the adhesion between the adhesive tape and the steering wheel, an anti-stick material can be coated on the steering wheel; or, grooves or perforated structures can be provided on the steering wheel, such as through knurling, to reduce the contact area between the steering wheel and the adhesive tape.

[0012] In one possible implementation, the support block includes a first support portion and a second support portion. The first support portion is close to the workpiece relative to the second support portion. The first and second support portions are connected to form a stepped structure. The cross-section of the first support portion is smaller than that of the second support portion. The shape of the first support portion is adapted to the shape of the groove on the workpiece where the release film is disposed. The surface of the first support portion facing the workpiece is the working surface. The distance between the working surface and the stepped structure is greater than the depth of the groove. In other words, in this implementation, to allow the support block to extend into the groove where the release film is disposed, the shape of the first support portion of the support block can be adapted to the shape of the groove. The second support portion of the support block and the first support portion can form a stepped structure. Furthermore, to prevent interference with the groove, the distance between the stepped structure and the working surface is greater than the depth of the groove.

[0013] In one possible implementation, multiple adhesive strips are spaced apart on the support block along the width direction of the adhesive strips. The surface of the support block facing the release film is planar, or the surface of the support block facing the workpiece includes multiple protrusions, and the multiple adhesive strips are respectively disposed on the multiple protrusions; or, the actuator includes multiple support blocks, which are spaced apart between the feeding mechanism and the receiving mechanism. That is, in this implementation, to improve work efficiency or adapt to different work needs, multiple adhesive strips can be arranged side by side; or, multiple support blocks can be arranged side by side.

[0014] In one possible implementation, the feeding mechanism and the receiving mechanism are disposed on a first side of the mounting plate. The mounting plate has a slot located between the feeding mechanism and the receiving mechanism. The actuator is disposed on the first side of the mounting plate corresponding to the slot. The release film recycling device further includes a drive mechanism located on a second side of the mounting plate opposite to the first side and connected to the actuator via the slot. The drive mechanism drives the actuator to move between the first position and the second position. In other words, in this implementation, the actuator and drive mechanism can be located on opposite sides of the mounting plate, thus reducing the area of ​​the mounting plate and consequently reducing its volume.

[0015] In one possible implementation, the feeding mechanism includes: a first axle, disposed on the mounting plate; a feeding wheel, rotatably mounted on the first axle, with one end of the tape connected to the feeding wheel and the unused section of the tape wound around the feeding wheel; a fastener, disposed on the first axle and spaced apart from the feeding wheel; and an elastic element compressed between the feeding wheel and the fastener. That is, in this implementation, the take-up wheel is the driving wheel, and the feeding wheel is the driven wheel. To prevent the feeding wheel from continuing to rotate due to inertia when the take-up wheel stops rotating, thus causing the tape to loosen, resistance can be applied to the feeding wheel by the fastener and the elastic element.

[0016] In one possible implementation, the receiving mechanism includes: a second axle disposed on the mounting plate; a receiving wheel rotatably mounted on the second axle, the other end of the adhesive tape being connected to the receiving wheel, and the section of the adhesive tape with the release film attached being wound around the receiving wheel; a motor and a drive belt, the motor being spaced apart from the receiving wheel and driving the receiving wheel to rotate via the drive belt. In other words, in this implementation, the adhesive tape with the release film attached can be recycled via the receiving wheel rotatably mounted on the second axle.

[0017] In one possible implementation, the receiving mechanism further includes: a photoelectric sensor fixedly mounted relative to the mounting plate; and an indexing disk coaxially mounted with the receiving wheel, the indexing disk having a plurality of indexing structures evenly distributed along its circumference, the indexing structures being used to allow or block the light signal from the photoelectric sensor. In other words, in this implementation, the angle of rotation of the receiving wheel can be measured using the photoelectric sensor and the indexing disk, thereby enabling the receiving wheel to move the tape by a predetermined length with each movement, and to perform fixed-length receiving of the tape with release film attached.

[0018] Other features and advantages of the present invention will be described in detail in the following detailed embodiments section. Attached Figure Description

[0026] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0027] In the description of this application, the terms “center,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0028] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection" and "joining" should be interpreted broadly, for example, they can be fixed connections, detachable connections, mating connections or integral connections; those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments.

[0030] To protect the components of electronic devices, many components are covered with release films before assembly. Taking a single circuit board as an example, various sizes of dustproof release films are present on the board. During the assembly process, the release films need to be peeled off before assembly. Due to the small size of the release films and their static electricity and stickiness, the collection of release film waste is difficult.

[0031] For example, manually peeling the release film off the workpiece is time-consuming and labor-intensive, which is not conducive to cost reduction. In addition, existing recycling devices use tape to stick the release film off the workpiece. Due to unreasonable structural design, the tape is prone to falling off or sticking together, which affects work efficiency and wastes tape, which is not conducive to cost reduction.

[0032] In view of this, this application provides a release film recycling device for the collection of release film waste in the electronics industry, such as the collection of release film in the single board assembly process. The device keeps the tape taut throughout the collection process, ensuring consistent tension before and after collection, making the tape run more smoothly, preventing the tape from loosening and falling off or sticking together, and avoiding tape waste. This helps to improve work efficiency and reduce costs.

[0033] Figure 1 This is a three-dimensional structural diagram of a release film recycling device provided in an embodiment of this application. Figure 2 for Figure 1 The diagram shows a three-dimensional representation of the release film recycling device with the actuator in the second position. Figure 1 and Figure 2 As shown, the release film recycling device includes at least one tape 1, a mounting plate 2, and a feeding mechanism 3 and a receiving mechanism 4 spaced apart on the mounting plate 2. The tape 1 can be a transparent tape. The first end of the tape 1 is connected to the feeding mechanism 3, which is used to store unused sections of the tape 1; the second end of the tape 1 is connected to the receiving mechanism 4, which is used to recycle the sections of the tape 1 to which the release film is attached.

[0034] The feeding mechanism 3 may include a first wheel shaft 31 and a feeding wheel 32. The first wheel shaft 31 is mounted on the mounting plate 2. The feeding wheel 32 is rotatably mounted on the first wheel shaft 31, one end of the tape 1 is connected to the feeding wheel 32, and the unused section of the tape 1 is wound around the feeding wheel 32.

[0035] Furthermore, the feeding mechanism 3 may also include fasteners and elastic elements. The feeding wheel 32 may be disposed on the first side of the mounting plate 2, and the fasteners and elastic elements may be disposed on the second side of the mounting plate 2 opposite to the first side, so the fasteners and elastic elements are not shown in the figure. Specifically, the fasteners are disposed on the first wheel shaft 31 and spaced apart from the feeding wheel 32. The elastic element is compressed and disposed between the feeding wheel 32 and the fasteners. For example, the fasteners may be nuts, the first wheel shaft 31 may be provided with external threads, the internal threads of the nuts may match the external threads of the first wheel shaft 31, and the nuts may be fitted on the first wheel shaft 31. The elastic element may be springs, which are fitted on the first wheel shaft 31. One end of the elastic element abuts against the feeding wheel 32, and the other end abuts against the fasteners. By using the compressed elastic element, such as a spring, to apply frictional force to the feeding wheel 32, constant speed feeding can be achieved, avoiding excessive speed of the feeding wheel due to motion inertia and loosening of the conveyor belt movement path.

[0036] The receiving mechanism 4 may include a second axle 41, a receiving wheel 42, a motor 43, and a drive belt. The drive belt may be located on the second side of the mounting plate 2, so it is not shown in the figure. The second axle 41 is mounted on the mounting plate 2. The receiving wheel 42 is rotatably mounted on the second axle 41, and the other end of the adhesive tape 1 is connected to the receiving wheel 42, with the section of the adhesive tape 1 having the release film attached wrapped around the receiving wheel 42. The motor 43 is spaced apart from the receiving wheel 42 and drives the receiving wheel 42 to rotate via the drive belt.

[0037] In addition, the receiving mechanism 4 may also include a photoelectric sensor and an indexing plate. The photoelectric sensor is fixedly mounted relative to the mounting plate 2. The indexing plate is coaxially mounted with the receiving wheel 42, so that the indexing plate and the receiving wheel 42 rotate at the same angle. The indexing plate has several indexing structures evenly distributed along its circumference, which are used to allow or block the light signal from the photoelectric sensor. The receiving wheel 42 is driven to rotate by a stepper motor 43, and the rotation angle of the receiving wheel 42 can be measured by the photoelectric sensor and the indexing plate, thus enabling fixed-length tape receiving.

[0038] In one example, the indexing structure is used to transmit light signals from a photoelectric sensor. The input and output ends of the photoelectric sensor are located on opposite sides of the indexing disk. The indexing structure may include an opening or a hole. The indexing disk includes a main body, and the hole may be located on the main body, or the opening may be located on the outer periphery of the main body. Thus, whether the input end of the photoelectric sensor receives the light signal from the output end can determine the rotation angle of the indexing disk. Specifically, when the light signal emitted from the output end of the photoelectric sensor passes through the opening or hole, and the input end receives the light signal, it can be determined that the rotation angle of the indexing disk has reached the set value.

[0039] In another example, the indexing structure is used to block the light signal from the photoelectric sensor. The input and output terminals of the photoelectric sensor are located on one side of the indexing disk. The indexing structure may include protrusions. The indexing disk includes a main body, and the protrusions extend beyond the outer peripheral edge of the main body; that is, multiple protrusions may be spaced apart along the outer peripheral edge of the main body. When the signal emitted from the output terminal of the photoelectric sensor is blocked by the protrusions and reflected back to the input terminal, the input terminal can receive the light signal, thus determining that the rotation angle of the indexing disk has reached the set value.

[0040] Continue to refer to Figure 1 and Figure 2 The release film recycling device also includes at least one actuator 5, located between the feeding mechanism 3 and the receiving mechanism 4. A portion of the tape 1 between the feeding mechanism 3 and the receiving mechanism 4 is wrapped around the at least one actuator 5, and the actuator 5 is movable between a first position and a second position, the second position being farther away from the workpiece on which the release film is applied relative to the first position. Figure 1 In the middle, executive agency 5 is in the first position; in Figure 2 In this context, the executive body occupies the second position.

[0041] In the first position, the adhesive side of the tape 1 wrapped around the working surface of the actuator 5 can contact the release film on the workpiece, so that the release film can be picked up when the actuator 5 moves towards the second position, thereby peeling the release film off the workpiece; and, when the actuator 5 moves between the first and second positions, the positions of the two ends of the tape 1 located between the feeding mechanism 3 and the receiving mechanism 4 remain unchanged. That is to say, the actuator 5 is an equal-length motion structure. Utilizing the principle of equal-length motion, with the feeding wheel 32 and the receiving wheel 42 stationary, the equal-length structure reciprocates between the first and second positions to complete the collection of the release film.

[0042] The feeding mechanism 3 and the receiving mechanism 4 can be arranged on the first side of the mounting plate 2. The mounting plate 2 is provided with a slot K, which is located between the feeding mechanism 3 and the receiving mechanism 4. The execution mechanism 5 is arranged on the first side of the mounting plate 2 corresponding to the slot K. The release film recycling device also includes a drive mechanism 8, which is located on the second side of the mounting plate 2 and is connected to the execution mechanism 5 through the slot K. The drive mechanism 8 is used to drive the execution mechanism 5 to move between the first position and the second position.

[0043] In one example, the drive stroke of the drive mechanism 8 can be set to restrict the movement of the actuator 5 between a first position and a second position. In another example, a limiting member (not shown in the figure) can be provided on the actuator 5, such as on the support plate 51, and a first positioning member and a second positioning member (not shown in the figure) can be provided at intervals on the mounting plate 2. The limiting member can move between the first positioning member and the second positioning member, thereby restricting the movement of the actuator 5 between the first position and the second position.

[0044] Furthermore, the release film recycling device can be equipped with one or more actuators 5. In this embodiment, the release film recycling device is mainly described with one actuator 5 as an example. In addition, the release film recycling device may also include a conveying mechanism (not shown in the figure), which is used to transport the workpiece with the release film to the first position.

[0045] In the release film recycling device of this application embodiment, since a portion of the tape between the feeding mechanism and the receiving mechanism is wrapped around the actuator, when the actuator moves between the first position and the second position, the positions of both ends of the tape between the feeding mechanism and the receiving mechanism remain unchanged. This causes the feeding mechanism, such as the feeding wheel, and the receiving mechanism, such as the receiving wheel, to remain stationary. Throughout the entire receiving process, the tape can be kept taut, ensuring consistent receiving tension, smoother operation, and preventing the tape from loosening, falling off, or sticking together. This improves work efficiency, avoids tape waste, and helps reduce costs.

[0046] Continue to refer to Figure 1 and Figure 2 The actuator 5 may include a support plate 51, a support block 52, and a steering wheel 53. The support block 52 is disposed at the end of the support plate 51 near the workpiece along the direction of movement. The steering wheel 53 is rotatably disposed on the support plate 51 between the feeding mechanism 3 and the support block 52, and is located away from the workpiece relative to the support block 52; the steering wheel 53 and the support block 52 are offset from each other. Alternatively, if necessary, the steering wheel 53 may also be fixedly disposed on the support plate 51.

[0047] The tape 1 is arranged sequentially around the steering wheel 53 and the support block 52, that is, the tape 1 is wrapped around the outer periphery of each part of the steering wheel 53 and the support block 52, and the adhesive surface of the tape 1 on the steering wheel 53 faces the steering wheel 53, while the adhesive surface of the tape 1 on the support block 52 faces away from the support block 52. The surface of the support block 52 facing the workpiece is the working surface. When the actuator 5 moves between the first position and the second position, the tape 1 can move around the steering wheel 53 and the support block 52. The change in length of the tape 1 between the feeding mechanism 3 and the steering wheel 53 is opposite to the change in length of the tape 1 between the support block 52 and the receiving mechanism 4, so that the positions of the two ends of the tape 1 between the feeding mechanism 3 and the receiving mechanism 4 remain unchanged.

[0048] Specifically, when the actuator 5 moves from the first position to the second position, the length of the conveyor belt 1 between the feeding mechanism 3 and the steering wheel 53 increases, and the length of the conveyor belt 1 between the support block 52 and the receiving mechanism 4 decreases, so that the positions of both ends of the conveyor belt 1 between the feeding mechanism 3 and the receiving mechanism 4 remain unchanged; when the actuator 5 moves from the second position to the first position, the length of the conveyor belt 1 between the feeding mechanism 3 and the steering wheel 53 decreases, and the length of the conveyor belt 1 between the support block 52 and the receiving mechanism 4 increases, so that the positions of both ends of the conveyor belt 1 between the feeding mechanism 3 and the receiving mechanism remain unchanged.

[0049] Furthermore, the release film recycling device may also include a first guide wheel 6 and a second guide wheel 7. The first guide wheel 6 is mounted on the mounting plate 2 on the side of the actuator 5 near the feeding mechanism 3, and is closer to the workpiece relative to the steering wheel 53 when the actuator 5 is in the first position. The second guide wheel 7 is mounted on the mounting plate 2 on the other side of the actuator 5 near the receiving mechanism 4, and is farther away from the workpiece relative to the steering wheel 53 when the actuator 5 is in the second position. To make the operation of the conveyor belt 1 smoother, both the first guide wheel 6 and the second guide wheel 7 are rotatably mounted on the mounting plate 2.

[0050] The tape 1 without release film passes around the first guide wheel 6, with the adhesive side of the tape 1 on the first guide wheel 6 facing outwards; the tape 1 with release film passes around the second guide wheel 7, with the adhesive side of the tape 1 on the second guide wheel 7 facing inwards; and the tape 1 between the first guide wheel and the steering wheel 53, the tape 1 between the steering wheel 53 and the support block 52, and the tape 1 between the support block 52 and the second guide wheel 7 extend along the moving direction of the actuator 5.

[0051] In order to ensure that the length change speed of the conveyor belt 1 between the feeding mechanism 3 and the steering wheel 53 is the same as the length change speed of the conveyor belt 1 between the support block 52 and the receiving mechanism 4, a first guide wheel 6 can be provided on the side of the steering wheel 53 near the feeding mechanism 3 so that the conveyor belt 1 between the first guide wheel 6 and the steering wheel 53 extends along the moving direction of the actuator 5. A second guide wheel 7 can be provided on the side of the steering wheel 53 near the receiving mechanism 4 so that the conveyor belt 1 between the support block 52 and the second guide wheel 7 extends along the moving direction of the actuator 5. Furthermore, the steering wheel 53 and the support block 52 are staggered, and the gap between the first guide wheel 6 and the steering wheel 53 can be the thickness of the conveyor belt 1, ensuring that the conveyor belt 1 between the steering wheel 53 and the support block 52 extends along the moving direction of the actuator 5.

[0052] When the actuator 5 moves between the first position and the second position, the change in length of the conveyor belt 1 between the first guide wheel 6 and the steering wheel 53 is opposite to the change in length of the conveyor belt 1 between the support block 52 and the second guide wheel 7, thus ensuring that the positions of both ends of the conveyor belt 1 between the feeding mechanism 3 and the receiving mechanism 4 remain unchanged. Specifically, when the actuator 5 moves from the first position to the second position, the length of the conveyor belt 1 between the first guide wheel 6 and the steering wheel 53 increases, and the length of the conveyor belt 1 between the support block 52 and the second guide wheel 7 decreases, so that the positions of both ends of the conveyor belt 1 between the feeding mechanism 3 and the receiving mechanism 4 remain unchanged; when the actuator 5 moves from the second position to the first position, the length of the conveyor belt 1 between the first guide wheel 6 and the steering wheel 53 decreases, and the length of the conveyor belt 1 between the support block 52 and the second guide wheel 7 increases, so that the positions of both ends of the conveyor belt 1 between the feeding mechanism 3 and the receiving mechanism remain unchanged.

[0053] Furthermore, the support block 52 may include a first support portion 521 and a second support portion 522. The first support portion 521 is closer to the workpiece than the second support portion 522. The first support portion 521 and the second support portion 522 are connected to form a stepped structure, and the cross-section of the first support portion 521 is smaller than the cross-section of the second support portion 522. The shape of the first support portion 521 is adapted to the shape of the groove on the workpiece where the release film is placed. The surface of the first support portion 521 facing the workpiece is the working surface, and the distance between the working surface and the stepped structure is greater than the depth of the groove. That is, the stepped structure serves to prevent interference between the second support portion 522 and the groove on the workpiece where the release film is placed. In addition, in order to prevent the edges of the support block 52 from damaging the tape 1 when the tape 1 rotates around the support block 52, rounded corners are provided on the two sides of the working surface of the first support portion 521 along the length direction of the tape 1.

[0054] Furthermore, to improve work efficiency or meet different work requirements, multiple adhesive tapes 1 are spaced apart on the support block 52 along the width direction of the adhesive tape 1. The surface of the support block 52 facing the release film is flat, or the surface of the support block 52 facing the workpiece includes multiple protrusions, and the multiple adhesive tapes 1 are respectively disposed on the multiple protrusions. At this time, the multiple adhesive tapes 1 can also be spaced apart on the feeding wheel 32 of the feeding mechanism 3, the steering wheel 53 of the execution mechanism 5, the receiving wheel 42 of the receiving mechanism 4, the first guide wheel 6, and the second guide wheel 7; the multiple adhesive tapes 1 can adhere to the release film at different positions on the same workpiece, or they can adhere to the release film on different workpieces.

[0055] Alternatively, the actuator 5 may include multiple support blocks 52, which are spaced apart between the feeding mechanism 3 and the receiving mechanism 4. The adhesive tape 1 on the working surface of the multiple support blocks 52 can adhere to release film at different locations on the same workpiece, or it can adhere to release film on different workpieces.

[0056] To reduce the adhesion between the tape 1 and the steering wheel 53, and to ensure consistent tension throughout the entire take-up process, preventing the steering wheel from sticking and causing machine malfunctions, an anti-stick material, such as Teflon (polytetrafluoroethylene), is applied to the outer circumference of the steering wheel 53 where it contacts the tape 1. This material utilizes the material's self-lubricating and non-stick (release properties) to reduce the viscosity between the surface of the steering wheel 53 and the tape 1. Optionally, to further reduce the contact area between the steering wheel 53 and the tape 1, multiple grooves or perforated structures are provided on the outer circumference of the steering wheel 53. For example, the steering wheel 53 may have a knurled surface treatment.

[0057] During the reciprocating motion of the actuator 5 between the first and second positions, the steering wheel 53 rotates back and forth. The adhesive surface of the tape 1 will repeatedly pass over the outer surface of the steering wheel 53. The steering wheel 53 is knurled and electroplated with Teflon to reduce surface viscosity, so that the steering wheel does not stick to the adhesive, ensuring that the entire material collection path is smooth and the machine does not stop.

[0058] In addition, Figure 1 and Figure 2 In this design, the steering wheel 53 may include a first rotating shaft 531 and a first cylindrical body 532. The first rotating shaft 531 is mounted on the mounting plate 2, and the first cylindrical body 532 is rotatably mounted on the first rotating shaft 531, for example, via a bearing. The outer surface of the first cylindrical body 532 may be knurled. Compared to a design where the outer surface of the first cylindrical body 532 is not knurled, knurling reduces the contact area between the first cylindrical body 532 and the tape 1 by 70%, leaving only 30% as the contact area. Optionally, an anti-stick material may also be provided on the outer surface of the first cylindrical body 532.

[0059] Figure 3 This is a schematic diagram of another type of steering wheel in the release film recycling device according to an embodiment of this application. Figure 4 for Figure 3 A side view of the first branch in another type of steering wheel is shown. Figure 3 and Figure 4 As shown, the steering wheel 53 may include a plurality of first branches F1 spaced apart in the circumferential direction. Each first branch F1 includes a second rotating shaft F11 and a second cylindrical body F12. The second rotating shaft F11 is mounted on the mounting plate 2, and the second cylindrical body F12 is rotatably mounted on the second rotating shaft F11. The outer surface of the second cylindrical body F12 may be provided with an anti-stick material. Optionally, knurling may also be provided on the outer surface of the second cylindrical body F12.

[0060] Figure 5 This is a schematic diagram of another type of steering wheel in the release film recycling device according to an embodiment of this application. Figure 6 for Figure 5This is a side view schematic diagram of the second branch structure in another type of steering wheel. (See diagram below.) Figure 5 and Figure 6 As shown, the steering wheel 53 may include a plurality of second branches F2 spaced apart in the circumferential direction. Each second branch F2 includes a third rotating shaft F21 and a plurality of balls F22. The third rotating shaft F21 is mounted on the mounting plate 2, and the plurality of balls F22 are rotatably mounted on the third rotating shaft F21. The outer surfaces of the plurality of balls F22 may be provided with an anti-stick material. Optionally, the outer surfaces of the plurality of balls F22 may also be knurled.

[0061] In summary, the release film recycling device may include a feeding mechanism 3, a receiving mechanism 4, and a belt steering transmission section. The feeding mechanism 3 may include a first axle 31, a feeding wheel 32, fasteners, and elastic elements. The receiving mechanism 4 may include a second axle 41, a receiving wheel 42, a motor 43, and a transmission belt. The belt steering transmission section may include an actuator 5, a first guide wheel 6, and a second guide wheel 7. The actuator 5 may include a support plate 51, a support block 52, and a steering wheel 53.

[0062] The take-up roller 42 is the driving roller, driven by a motor 43 and a transmission belt. The rotation angle is measured by a photoelectric sensor and an indexing plate to achieve equidistant movement of the tape 1, thereby collecting the tape with the release film attached. The feed roller 32 is the driven roller, primarily feeding the tape equidistantly through internal shaft friction (generated by compression between the fastener and the take-up roller 42 via an elastic element) in conjunction with the driving roller. The tape steering transmission section, used to change the direction of tape transmission, is the main working component. The adhesive side of the tape is used to adhere the release film, and the steering roller 53 is used to align the adhesive side of the tape towards the release film on the workpiece. One or more steering rollers 53 can be provided as needed.

[0063] Since contact between the steering wheel 53 and the adhesive surface of the tape 1 is unavoidable, and the steering wheel 53, as a wheel-driven structure, is mostly made of aluminum, it is prone to sticking when the adhesive surface of the transparent tape passes over the steering wheel 53, causing a change in the entire motion path and mechanism malfunction. To prevent the steering wheel 53 from sticking to the tape, the material properties and surface treatment of the material can be changed to reduce the viscosity of the steering wheel, ensuring consistent tension throughout the entire material collection process and preventing the steering wheel from sticking and causing malfunction. Specifically, the viscosity can be reduced by using knurling on the surface of the roller (i.e., the steering wheel) and electroplating with an anti-stick material such as Teflon.
