Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of film laminating machine, especially relates to a stripping module and cutting module. BACKGROUND

[0002] In production, the film material is double-layered when coming out of the decoiler, one layer is the film with adhesive, and the other layer is the release film for preventing adhesion, the release film at the bottom is equivalent to the packaging material and does not participate in the actual attachment to the product, so it is necessary to peel off the release film and then cut the film with adhesive, and then attach the cut film with adhesive to the product for use. When stripping the release film, the existing structure mainly clamps one end of the release film by a clamp, and then applies a certain external force to drag it from the film material, so as to realize the separation of the two layers of film. Although the operation is simple, there is no appropriate structure to support the film with adhesive after being peeled off, which is easy to cause curling or wrinkling of the film with adhesive, and the wrinkled film with adhesive after being peeled off will be directly scrapped, thereby reducing the product yield. Secondly, the dragging of external force is easy to cause slight deformation of the film body, especially the deformation of the film with adhesive, which will directly affect the yield of the product film laminating, causing resource waste. Therefore, it is necessary to design a stripping module and cutting module to solve these problems. SUMMARY

[0003] The utility model solves the problem of providing a stripping module and cutting module, which can quickly strip the release film, ensure the stability and smoothness of the stripping process, and will not cause curling or wrinkling of the film with adhesive, or even deformation, which helps to improve the yield of the peeled film body.

In the description of the utility model, the meaning of "a plurality of" is two or more, unless otherwise specified.

[0027] The utility model will be further described below in combination with embodiments and drawings:

[0028] It needs to be noted that, in the embodiment, the film material 400 is double-layered when it comes out of the uncoiler, one layer is a film with adhesive (namely the upper film 410), and the other layer is a release film (namely the lower film 420), the release film needs to be peeled from the film material, and the upper film 410 needs to be cut and attached to the product surface. The film material 400 is pulled out to a proper degree in the process that the peeling module moves from right to left, and the peeling module gives the film material 400 a certain supporting force and pulling force to pull the film material 400 to move left to the peeling position and stop. Then the peeling module is driven to move from left to right, and the lower film 420 is quickly peeled at the same time, and the upper film 410 is relatively stationary at this time, and can be quickly cut and attached after peeling.

[0029] The technical scheme adopted by the utility model is: Figure 1 and Figure 2 As shown in a kind of peeling module, peeling module includes:

[0030] Fixed frame 100;

[0031] The feeding assembly is arranged on the fixed frame 100 and used for providing the film material 400, which comprises an upper film 410 and a lower film 420 adhered to each other;

[0032] The movable assembly is arranged on the fixed frame 100 and comprises a support 310 in contact with the side of the lower film 420 away from the upper film 410, and a winding assembly used for winding the lower film 420;

[0033] The driving assembly 500 is arranged on the fixed frame 100 and provides power for the movement of the support 310;

[0034] The movable assembly is configured to move the support 310 towards the feeding assembly when the upper film 410 is static, so as to peel the lower film 420 from the upper film 410 and wind the lower film 420 in the winding assembly 320. In the embodiment, the film material 400 is first pulled out to the left by a suitable length, and then the movable assembly is driven to move the support 310 to the right, while the winding assembly 320 is driven to rotate clockwise to wind the lower film 420, and the winding of the lower film 420 is accompanied by a rightward pulling force to peel the lower film 420 from the upper film 410. Figure 2 As shown in the figure, at this time, the film material 400 is located at the peeling position, the feeding assembly stops feeding, the upper film 410 is in a static state relative to the lower film 420, the driving assembly 500 drives the support 310 to move to the right, and the winding assembly 320 rotates clockwise to wind the lower film 420. At the same time of winding, the lower film 420 is peeled from the upper film 410 by the rightward pulling force. The support 310 stably supports the film material 400 from below to prevent the upper film 410 from curling or wrinkling and self-adhering, unnecessary movement or deviation during the peeling process, avoid the peeling error caused by the change of position, and further avoid the slight deformation of the upper film 410 caused by the dragging, which helps to improve the product sticking film yield. By controlling the moving speed of the support 310 and matching the winding speed of the winding assembly 320, the peeling force can be controlled to be moderate and uniform, avoiding too small force leading to slow peeling speed and time delay, and also avoiding too large force leading to deformation or damage of the upper film 410, which helps to improve the production efficiency.

[0035] It should be noted that, during the peeling process, the lower film 420 is subjected to the rightward pulling force from the winding roller 321 and the leftward pulling force from the support 310, and the rightward pulling force from the winding roller 321 is greater than the leftward pulling force from the support 310, so that the peeling process can be kept stable and smooth. Correspondingly, the film material 400 is subjected to the rightward pulling force from the feeding roller 210 and the leftward pulling force from the support 310, and the two forces are of the same size to ensure that the film material 400 is relatively static during the peeling process. This design can better control the peeling force, avoid curling, wrinkling or damage of the upper film 410, ensure the product quality, and save costs.

[0036] Preferably, the support member 310 comprises a first support plate 311, a second support plate 312 connected to the first support plate 311, and an arc-shaped support plate 313 connected to both the first support plate 311 and the second support plate 312 and curved away from the feeding assembly. During the rightward peeling process, the first support plate 311 and the arc-shaped support plate 313 directly contact the lower layer film 420, and the two cooperate with each other to provide stable support, which also helps to maintain the shape and stability of the upper layer film 410 after the release film (i.e. the lower layer film 420) is peeled off, ensuring that the product does not curl, wrinkle, self-adhere, deform or be damaged due to loss of support during the peeling process. In addition, the arc-shaped support plate 313 can significantly improve the efficiency and quality of peeling the release film, as it reduces product damage and rework rates caused by improper operation or insufficient support, and improves production efficiency and product quality. At the same time, the design of the arc-shaped support plate 313 can also be adjusted and optimized according to the shape and needs of specific products to better meet the actual needs in the production process, and has better adaptability.

[0037] Preferably, the movable assembly further comprises a locking member 330 for mounting and fixing the support member 310 on the driving assembly 500, the locking member 330 comprising a bolt 331 penetrating through the support member 310 and a nut 332 cooperating with the bolt. In this embodiment, the first support plate 311, the second support plate 312 and the arc-shaped support plate 313 are designed as one piece, which is wrapped around the outside of the support rod 520 and is mounted and fixed on the support rod 520 by the bolt 331 and the nut 332, so as to realize synchronous movement of the support rod 520 and the support member 310.

[0038] Preferably, the movable assembly further comprises a suction cup 340 arranged on the fixed frame 100 for holding the upper layer film 410. In this embodiment, the suction cup 340 here is a flat suction cup 340 connected to the robot arm. When the support member 310 moves to the left to the peeling position, the feeding assembly stops feeding, and at this time the film material 400 is in a stationary state. The suction cup 340 is driven by the robot arm to hold the upper layer film 410, which on the one hand can prevent unnecessary movement or deviation of the upper layer film 410 during the peeling process, helping to ensure the accuracy and precision of the peeling, and thus ensuring the flatness of the upper layer film 410, and on the other hand, the relatively fixed upper layer film 410 can simplify the process of peeling operation, reducing the time and effort spent on adjusting the position of the upper layer film, which helps to improve the overall efficiency of the peeling work.

[0039] Preferably, as shown in Figure 4 the driving assembly 500 comprises a rack 510 symmetrically arranged on the fixed frame 100, a gear 520 engaged with the rack 510, and a support rod 530 connecting adjacent gears 520, the support rod 530 being rotatably connected to the gear 520, and the support member 310 being wrapped around the outside of the support rod 530 and abutting against the lower layer film 420.

[0040] Preferably, the support rod 530 is coaxially arranged with the gear 520 and rotatably connected to the gear 520 via a bearing. In this embodiment, the support rod 530 and the gear 520 are rotatably connected. As the gear 520 rotates on the rack 510, it can drive the support rod 530 to move left and right, thereby driving the support member 310 to move left and right.

[0041] Preferably, gear 520 is connected to a drive motor, providing power for its rotation. In this embodiment, the drive motor drives gear 520 to rotate, thereby causing support rod 530 and support member 310 mounted on support rod 530 to move left and right together. Figure 3 As shown, starting from the initial position, gear 520 rotates counterclockwise, driving support rod 530 and support member 310 to move to the left, thereby pulling feed roller 210 to rotate counterclockwise to release film 400. At the same time, winding roller 321 rotates counterclockwise to release lower film 420. At this time, the moving speed of support member 310, in coordination with the rotation of feed roller 210 and winding roller 321, pulls film 400 to the left by an appropriate length. Here, lower film 420 is subjected to both the leftward pulling force of support member 310 and the rightward pulling force of winding roller 321 to ensure its smooth movement. Correspondingly, film 400 released from feed roller 210 is also subjected to both the leftward pulling force of support member 310 and the rightward pulling force of feed roller 210 to smoothly pull film 400 to the left.

[0042] Preferably, the roll assembly 320 includes a roll roller 321 connected to the fixed frame 100 and a roll motor for driving the roll roller 321 to rotate, and the feeding assembly includes a feeding roller 210 disposed on the fixed frame and a feeding motor for driving the feeding roller to rotate.

[0043] Preferably, the mounting frame 100 is equipped with a vision system for detecting the position of the film material. In this embodiment, multiple cameras are provided above the film material 400 to detect parameters such as the coordinates and angles of the pattern on the upper film 410 and feed them back to the robot arm, which then instructs the robot arm to drive the suction cup 340 to hold the upper film 410, preparing it for the peeling process. This helps to improve the level of automation and increase production efficiency.

[0044] A cutting module, applicable to the peeling module described above, includes a cutter mounted on a fixing frame 100 for cutting the upper layer film 410. The cutter consists of two blades that cut vertically. In this embodiment, when the peeling module moves to the right to its initial position, a set of release films is peeled off. Two blades that cut vertically are located on the left side of the peeling module. Driving the cutter cuts the peeled upper layer film 410. Subsequently, a robotic arm drives a suction cup to move the adsorbed upper layer film 410 to the cutting station for cutting and then laminating.

[0045] By adopting the technical scheme, the support member abutting against the lower layer film (i.e. the release film) is arranged at the bottom of the lower layer film, so that the film material can be stably supported during movement and peeling, and the upper layer film is prevented from being curled or wrinkled and self-adhered during peeling, thereby avoiding great waste of resources, and the film material is also prevented from being unnecessarily moved or deviated during peeling, thereby avoiding peeling errors caused by position changes, and further avoiding slight deformation of the upper layer film caused by dragging, so as to help improve the product film pasting yield. By controlling the moving speed of the support member and cooperating with the winding speed of the winding assembly, the peeling force can be reasonably controlled to be moderate and uniform, so as to avoid too small force leading to too slow peeling speed and time delay, and also avoid too large force leading to deformation or damage of the upper layer film, so as to help improve the yield of the peeled film body and improve the overall production efficiency.

[0046] The embodiments of the utility model are described in detail above, but the content is only the preferred embodiment of the utility model, and cannot be considered as limiting the implementation range of the utility model. Any equivalent change and improvement within the application range of the utility model should still belong to the patent coverage range of the utility model.
