Visual positioning mechanism and laminator

Abstract

This application provides a visual positioning mechanism and a stacking machine. The visual positioning mechanism includes a positioning bracket and four camera units, which are spaced apart and mounted on the positioning bracket. This application utilizes positioning holes at the four corners of an electrode diaphragm. The four camera units are spaced apart on the positioning bracket and positioned directly opposite the four positioning holes. When the electrode diaphragm passes under the positioning bracket, if each of the four camera units detects one of the four positioning holes, the electrode diaphragm is determined to be in the correct position. If at least one of the four camera units fails to detect a corresponding positioning hole, the electrode diaphragm is determined to be misaligned and requires adjustment. The stacking machine using this visual positioning mechanism helps improve the feeding accuracy of the electrode diaphragms, thereby improving the stacking accuracy of multiple electrode diaphragms and enhancing the stacking quality of the product.

[0001] This application belongs to the field of lamination technology, and more specifically, relates to a visual positioning mechanism and a lamination machine using the visual positioning mechanism. Background Technology

[0002] A laminating machine is a device that stacks multiple electrode films together to form a product. The electrode films are automatically fed by a film feeding mechanism, then positioned by a positioning mechanism, and cut by a film cutting mechanism. Finally, multiple electrode films are stacked together to form the final product. Among these, the positioning mechanism's positioning of the electrode films directly affects the stacking accuracy of subsequent electrode films, which places high demands on the positioning mechanism.

[0003] Currently, positioning holes are provided at both ends of the electrode diaphragm, and the positioning mechanism uses two cameras aligned with the two positioning holes to achieve positioning. However, the dual-hole positioning method still suffers from electrode diaphragm misalignment, resulting in poor product quality when multiple electrode diaphragms are stacked together.

[0036] Please see Figure 1 The visual positioning mechanism provided in this application embodiment will now be described. This visual positioning mechanism is used to position an electrode diaphragm, which has a square structure, such as a rectangle or square. Positioning holes are respectively provided at the four corners of the electrode diaphragm. Specifically, the visual positioning mechanism includes a positioning bracket 1 and four camera units 2. The positioning bracket 1 is mounted on the frame of the laminating machine and can be positioned above the electrode diaphragm. The four camera units 2 are spaced apart on the positioning bracket 1, all four camera units 2 being located above the electrode diaphragm, and each of the four camera units 2 is positioned directly opposite the four positioning holes. This structure, by providing positioning holes at the four corners of the electrode diaphragm and by spaced apart on the positioning bracket 1, allows for effective positioning of the four electrode diaphragms. When the electrode diaphragm passes under the positioning bracket 1, if the four camera units 2 detect the four positioning holes respectively, it is determined that the electrode diaphragm is in the correct position; if at least one of the four camera units 2 fails to detect the corresponding positioning hole, it is determined that the position of the electrode diaphragm is deviated and the position of the electrode diaphragm needs to be adjusted.

[0037] In one embodiment, see Figure 2 and Figure 3As a specific embodiment of the visual positioning mechanism provided in this application, each camera unit 2 includes a mounting bracket 21, a camera body 22, a support frame 23, and a camera lens 24. The mounting bracket 21 is mounted on the positioning bracket 1, the camera body 22 and the support frame 23 are respectively mounted on the mounting bracket 21, and the camera lens 24 is mounted on the support frame 23. The camera lens 24 is located directly below the camera body 22, and the support frame 23 has a clearance hole 231 connecting the camera body 22 and the camera lens 24. Specifically, the mounting bracket 21 can be mounted on the positioning bracket 1 using fasteners such as screws and bolts, thus achieving a detachable connection of the mounting bracket 21. The camera lens 24 can be mounted on the support frame 23 using fasteners such as screws and bolts, thus achieving a detachable connection of the camera lens 24. In this structure, the mounting bracket 21 can support the camera body 22; the support frame 23 can support the camera lens 24; and the clearance hole 231 allows light from the camera body 22 to pass through the camera lens 24. Among them, the camera body 22 and the camera lens 24 are commonly used cameras on the market, such as CCD (Charge Coupled Device) cameras.

[0038] In one embodiment, see Figure 2 and Figure 3 As a specific embodiment of the visual positioning mechanism provided in this application, each mounting bracket 21 includes a first bracket 211 and a second bracket 212. The first bracket 211 is mounted on the positioning bracket 1, and the second bracket 212 is connected to the first bracket 211. The first bracket 211 has a first through hole 2111, and the second bracket 212 has a second through hole 2121. The first through hole 2111 and the second through hole 2121 enclose an area through which the camera body 22 passes. The second bracket 212 and the first bracket 211 can be detachably connected by fasteners such as screws and bolts. Both the first through hole 2111 and the second through hole 2121 can be semi-circular holes, forming a circular area. This structure allows for the clamping and fixing of the camera body 22 through the second bracket 212 and the first bracket 211. By clamping the camera body 22 at different positions, the position of the camera body 22 mounted on the mounting bracket 21 can be adjusted, thereby adjusting the distance between the camera body 22 and the camera lens 24.

[0039] In one embodiment, see Figure 3As a specific embodiment of the visual positioning mechanism provided in this application, each mounting bracket 21 has a first mounting hole 2112, which can be formed on the first bracket 211; each support frame 23 has a second mounting hole 232, and each second mounting hole 232 is connected to the corresponding first mounting hole 2112 by fasteners such as screws and bolts. Each first mounting hole 2112 is an elongated hole; or, each second mounting hole 232 is an elongated hole; or, both the first mounting hole 2112 and the second mounting hole 232 are elongated holes. With this structure, by adjusting the position of the support frame 23 mounted on the mounting bracket 21, the distance between the camera lens 24 and the camera body 22 can be adjusted, thereby adjusting the image clarity of the camera unit 2. In this embodiment, each second mounting hole 232 is an elongated hole.

[0040] In one embodiment, see Figure 1 As a specific embodiment of the visual positioning mechanism provided in this application, the visual positioning mechanism further includes two through-beam detectors 3, which are respectively mounted on the positioning bracket 1 and arranged at a distance from each other. One through-beam detector 3 is located between the two camera units 2 on the left side, and the other through-beam detector 3 is located between the two camera units 2 on the right side. In this structure, the two through-beam detectors 3 can be used to detect the presence of an electrode diaphragm. If an electrode diaphragm is detected, the four camera units 2 perform position detection on the electrode diaphragm; if no electrode diaphragm is detected, the four camera units 2 do not perform detection.

[0041] In one embodiment, see Figure 4 As a specific embodiment of the visual positioning mechanism provided in this application, each through-beam detector 3 includes a detector body 31, an through-beam support 32, and an through-beam adjustment frame 33. The through-beam support 32 is mounted on the positioning support 1, one end of the through-beam adjustment frame 33 is mounted on the through-beam support 32, and the other end of the through-beam adjustment frame 33 is connected to the detector body 31. The detector body 31 is a commonly used detector on the market and will not be described in detail here. This structure allows for adjustment of the position of the detector body 31 via the through-beam adjustment frame 33, thereby adjusting the distance between the two detector bodies 31, thus adapting to electrode films of different sizes.

[0042] In one embodiment, see Figure 4As a specific implementation of the visual positioning mechanism provided in this application, each through-beam adjustment frame 33 includes a first through-beam support 331, a second through-beam support 332, a first through-beam guide rod 333, and a second through-beam guide rod 334. The first through-beam guide rod 333 connects the first through-beam support 331 and the second through-beam support 332. A detector body 31 is installed at one end of the first through-beam support 331, and the other end of the first through-beam support 331 is sleeved on one end of the first through-beam guide rod 333. One end of the second through-beam support 332 is sleeved on the other end of the first through-beam guide rod 333, and the other end of the second through-beam support 332 is sleeved on one end of the second through-beam guide rod 334. The through-beam bracket 32 ​​is sleeved on the other end of the second through-beam guide rod 334. This structure allows for multi-directional adjustment of the detector body 31's position by adjusting the positions of the first beam support 331 and the second beam support 332 on the first beam guide rod 333, and by adjusting the positions of the beam bracket 32 ​​and the second beam support 332 on the second beam guide rod 334.

[0043] In one embodiment, see Figure 4 As a specific embodiment of the visual positioning mechanism provided in this application, the first pair of beam guide rods 333 is arranged horizontally, and the second pair of beam guide rods 334 is arranged vertically, with the first pair of beam guide rods 333 perpendicular to the second pair of beam guide rods 334. The first pair of beam support base 331 is mounted on the first pair of beam guide rods 333 using screws, bolts, or other fasteners; both ends of the second pair of beam support base 332 are respectively mounted on the second pair of beam guide rods 334 using screws, bolts, or other fasteners; and the beam bracket 32 ​​is mounted on the second pair of beam guide rods 334 using screws, bolts, or other fasteners. With this structure, the horizontal positions of the first pair of beam support bases 331 and 332 can be adjusted using the first pair of beam guide rods 333, and the vertical position of the second pair of beam support bases 332 can be adjusted using the second pair of beam guide rods 334. This allows for multi-directional adjustment of the detector body 31 in both the horizontal and vertical directions.

[0044] In one embodiment, see Figure 1 As a specific embodiment of the visual positioning mechanism provided in this application, the visual positioning mechanism further includes a dust collector 4 mounted on the positioning bracket 1. The dust collector 4 can be installed above the two through-beam detectors 3. The dust collector 4 can be a currently available device commonly used in the market. With this structure, the dust collector 4 can perform dust removal on the electrode diaphragm, thereby achieving cleaning of the electrode diaphragm.

[0045] This application also provides a laminating machine, including the visual positioning mechanism provided in any of the above embodiments. This structure involves creating positioning holes at the four corners of the electrode film and installing four camera units 2 spaced apart on the positioning bracket 1, each camera unit 2 facing one of the four positioning holes. When the electrode film passes under the positioning bracket 1, if the four camera units 2 detect the four positioning holes, the electrode film is determined to be in the correct position; if at least one of the four camera units 2 fails to detect the corresponding positioning hole, the position of the electrode film is determined to be deviated, requiring adjustment. The laminating machine using this visual positioning mechanism helps improve the feeding accuracy of the electrode films, thereby improving the stacking accuracy of multiple electrode films and enhancing the stacking quality of the product.
