Technical Field

[0001] This utility model relates to the field of film peeling technology, and in particular to a material positioning mechanism and a film peeling machine for applying auxiliary materials and maintaining pressure. Background Technology

[0002] When tearing film from a film-tearing machine, precise positioning of the material is crucial; otherwise, the machine's robotic arm may fail to grasp the transparent film, resulting in a failed tear. To ensure accurate tearing, current film-tearing machines typically employ precise alignment to transfer the material onto a carrier. This precise transfer usually involves capturing images with a camera, then using image recognition to mark points or compare positions, followed by precise control of the material transfer. However, this precise transfer technology is relatively expensive. Therefore, it is essential to develop a lower-cost material positioning mechanism to facilitate accurate material transfer. Summary of the Invention

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0026] The present invention will now be described in detail with reference to the accompanying drawings. Figures 1 to 7 As shown.

[0027] Example 1: See Figures 1 to 3A material positioning mechanism includes a carrier 1, which has a material placement area 11. One side of the carrier 1 along its length has a through hole 12, and one end of the through hole 12 has a plug 17. The material placement area 11 has several sets of linearly arranged recesses 15. The bottom surface of the recesses 15 has a connecting hole 14, which communicates with the through hole 12 and is connected to a suction nozzle 16. The upper end of the suction nozzle 16 is located inside the recesses 15. The left end and the front end of the carrier 1 are respectively provided with upwardly protruding positioning blocks 13. The mechanism also includes a right pushing mechanism 3 and a rear pushing mechanism 2 for pushing the material. The right pushing mechanism 3 and the rear pushing mechanism 2 are located on the right side and the rear side of the carrier 1, respectively.

[0028] In use, one end of the perforation 12 is connected to a suction device, such as a vacuum pump, via a pipe, so that the material is adsorbed and fixed during material positioning; two perforations 12 can be provided, such as... Figure 2 , Figure 3 As shown, there are two sets of corresponding recesses 15. In the initial stage, the air pump does not work; or the air is not pumped out of the perforation 12 by controlling the switch valve; or the air pumping power is small and insufficient to fix the material. The material is transferred to the material placement area 11 of the carrier 1 by the transfer mechanism. It can be understood that the size of the material placement area 11 can be set to be less than or equal to the size of the material. Therefore, after the material is placed, the right end and rear end of the material may be exposed on the carrier 1. Then the right pushing mechanism 3 and the rear pushing mechanism 2 act respectively to push the material. The pushing can be sequential. For example, the right pushing mechanism 3 first pushes the material to the left, so that the material is against or close to the positioning block 13 at the left end. At this time, the pressure of the right pushing mechanism 3 on the material is very small. It can be calculated that the distance between the pushing surface of the right pushing mechanism 3 and the side of the positioning block 13 at the left end is equal to or very close to the length of the material in the left and right direction, such as about 0.1 mm apart. The rear pushing mechanism 2 then pushes forward, while the right pushing mechanism 3 remains unchanged. The rear pushing mechanism 2 pushes the material forward until it comes into contact with or approaches the positioning block 13 on the front side, with a proximity distance of about 0.1 mm. At this point, it is considered that the material has entered the material placement area 11. Then, the suction device works or the suction power is increased, and the suction nozzle 16 adsorbs and fixes the material on the carrier 1. The upper end surface of the suction nozzle 16 is flush with or slightly lower than the surface of the material placement area 11, such as about 0.1 mm lower; thus, the positioning of the material is completed.

[0029] See Figure 5 , Figure 4The rear pushing mechanism 2 includes a rear cylinder 21. The push block 22 of the rear cylinder 21 is connected to a push plate 23. The left and right ends of the push plate 23 are respectively provided with mounting holes and connected to linear bearings 26. The linear bearings 26 are sleeved with push rods 24. One end of the push rod 24 is inserted into the linear bearing 26 and is provided with a connecting hole. It is connected to a cover 29 through a connector 210. The cover 29 abuts against the end face of the linear bearing 26. The other end of the push rod 24 is connected to a flexible sleeve 28 and a limiting sleeve 25 is sleeved on it. The limiting sleeve 25 is located between the flexible sleeve 28 and the linear bearing 26.

[0030] The rear pushing mechanism 2 uses a rear cylinder 21 as its power source to move the push plate 23, which in turn moves the push rod 24 forward, pushing the material forward. In this embodiment, the maximum stroke of the rear cylinder 21 is required during operation; that is, when the rear cylinder 21 drives the push rod 24 to move the maximum distance, the push rod 24 can push the material to a predetermined position. Due to measurement errors, to eliminate these errors, this embodiment uses a linear bearing 26 and a cover 29. Initially, the cover 29 and the limiting sleeve 25 can be disassembled, allowing the push rod 24 to move relative to the linear bearing 26 and be positioned further forward, thus pushing the material forward. When the push rod 24 pushes the material forward until it abuts against the positioning block 13 on the front side, the cylinder may still be pushing against the linear bearing 26. The push rod 24 will move relative to the linear bearing 26 until the cylinder push block moves to its maximum stroke. At this time, the cover 29 is connected to the push rod 24 through the connector 210, and the cover 29 abuts against the linear bearing 26. At the same time, the distance between the flexible sleeve 28 and the linear bearing 26 is recorded. The upper limit sleeve 25 is then installed. The length of the upper limit sleeve 25 is equal to or slightly larger than this distance, such as about 0.1 mm larger. The next time the push rod is pushed, the material can be accurately pushed into the material placement area 11. The upper limit sleeve 25 can prevent the push rod 24 from moving backward relative to the linear bearing 26. The flexible sleeve 28, the upper limit sleeve 25 and the push rod 24 can be connected by mating or interference fit, and can be installed by thermal expansion and contraction.

[0031] The connecting hole can be a threaded hole, and the connecting part 210 can be a bolt. It is understood that the threaded hole is relatively deep and the bolt shank is also relatively long, so that there is enough distance to adjust the connection position of the bolt. The rear end of the push rod 24 does not extend out of the linear bearing 26 to ensure that the cover 29 can abut against the end of the linear bearing 26.

[0032] Secondly, it is understandable that the friction between the push rod 24 and the linear bearing 26 is greater than the friction between the material and the carrier 1, so that in the early stage, the push rod 24 can push the material into the material placement area 11 and abut or approach the positioning block 13 on the front side.

[0033] Since different materials have different dimensions, in order to prevent the push rod 24 from pushing the material to collide with the positioning block 13 on the front side during the later positioning process, which may cause damage to the material, a flexible sleeve 28 is connected to the front end of the push rod 24 in this embodiment. The flexible sleeve 28 can be a rubber sleeve, silicone sleeve, etc., and has a certain degree of elasticity. It can both push the material into the material placement area 11 and prevent rigid collision.

[0034] Secondly, during the pushing process, the lower end face of the flexible sleeve 28 can be lower than the surface of the material placement area 11, and the flexible sleeve 28 can be pushed until it abuts against the side of the carrier 1.

[0035] See Figure 4 , Figure 5 The front end of the linear bearing 26 is connected to a flange 27, which is fixedly connected to the push plate 23.

[0036] To facilitate the fixing of the linear bearing 26, in this embodiment, a linear bearing 26 with a flange 27 connected to the front end is selected. The flange 27 is fixedly connected to the push plate 23, which facilitates installation and disassembly.

[0037] See Figure 5 The rear pushing mechanism 2 also includes a rear support frame 212 connected to the rear cylinder 21. The rear support frame 212 is provided with a rear support plate 211. The rear support plate 211 is provided with a rear connecting groove 213 in the front-rear direction. The rear cylinder 21 is provided with a connecting hole and is fixedly connected to the rear support plate 211 through the rear connecting groove 213 via a connector.

[0038] The connecting hole can be a threaded hole, and the connecting part can be a bolt; the rear connecting groove 213 is provided to adjust the front and rear positions of the rear cylinder 21, so as to facilitate better adjustment of the position of the push rod 24.

[0039] See Figure 6 The right pushing mechanism 3 includes a right cylinder 31, and the push block of the right cylinder 31 is connected to a right flexible block 32.

[0040] The right flexible block 32 can be made of materials such as rubber or silicone; the material is pushed by the right cylinder 31, so that the material enters the material placement area 11; the lower end of the right flexible block 32 is lower than the surface of the material placement area 11, and when pushing, it continues until the right flexible block 32 abuts against the side of the carrier 1; in specific settings, the size of the material placement area 11 is consistent with the size of the material.

[0041] See Figure 6 The right pushing mechanism 3 also includes a right bracket 37, which includes a right support plate 33. The lower end of the right cylinder 31 is connected to a right base plate 34. The right base plate 34 has right connecting grooves 35 in the left and right directions on both sides. The right support plate 33 has connecting holes. The right base plate 34 is connected to the right support plate 33 through a connector.

[0042] To facilitate the adjustment of the position of the right cylinder 31, this embodiment provides a right connecting groove 35 and connecting holes, etc.; the connecting holes and connecting parts can be threaded holes and screws, etc.

[0043] In this embodiment, the right pushing mechanism 3 is mainly used to push the wide side of the material, and the rear pushing mechanism 2 is mainly used to push the long side of the material; the structures of the right pushing mechanism 3 and the rear pushing mechanism 2 can be interchanged and selected as needed.

[0044] See Figure 6 The right bracket 37 is connected to a vertically arranged electric cylinder 36, and the push block of the electric cylinder 36 is connected to the right support plate 33.

[0045] The electric cylinder 36 allows for adjustment of the height of the right support plate 33 and the right cylinder 31, thereby adjusting the height of the right flexible block 32. When the lower end face of the right flexible block 32 needs to be flush with the surface of the material placement area 11, the height of the right cylinder 31 can be adjusted. The right cylinder 31 can drive the right flexible block 32 into the carrier 1. Of course, the electric cylinder 36 can be replaced with other linear modules, such as cylinders.

[0046] Example 2: See Figure 7 A pressure-holding film-peeling machine for applying auxiliary materials includes the aforementioned material positioning mechanism 100.
