Description

Technical Field

[0001] This utility model relates to the field of mobile phone screen separation technology, and in particular to a positioning adjustment mechanism and a laser screen removal machine. Background Technology

Laser scanning for adhesive removal requires finding a reference plane for the laser focus to maximize its effectiveness. When placing products of varying thicknesses on a worktable, this reference plane remains constant. The product surface needs to be aligned with this reference plane; currently, manual adjustments are inaccurate and inefficient. Summary of the Invention

The worktable is fixedly connected to the second slider. The height measuring mechanism is rotatably connected to the first slider. A positioning sensing plate is detachably arranged on the positioning plate, and a sensor is arranged on the first slider.

[0005] Preferably, the positioning plate has a plurality of positioning holes for mounting the positioning sensor sheet.

[0006] Preferably, the positioning plate is provided with limit blocks at both ends to restrict the movement of the first slider and the second slider.

[0007] A laser screen removal machine, including the aforementioned positioning and adjustment mechanism, comprises a first side plate disposed on one side of the workbench, wherein a fresh air deodorization device is disposed on the first side plate.

[0008] Preferably, it also includes a laser generator; the laser generator is disposed on the partition plate, a reflector is disposed above the laser generator, a galvanometer is disposed on the side of the reflector, and a field mirror is disposed below the galvanometer.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. The heat generated by the laser can remove the paint layer on the back of the phone's outer screen, thus removing the adhesive from the phone frame and allowing the phone screen assembly to be manually removed from the frame.

[0011] The system automatically positions mobile phone surfaces of different thicknesses onto the reference surface of the laser focal point through the cooperation of the drive device, the first slider, the second slider, the height measuring mechanism, and the positioning sensor.

[0018] This embodiment proposes a laser screen removal machine, including a chassis 100, a positioning and adjustment mechanism, a worktable 300, and a laser generator 400. The positioning and adjustment mechanism includes a positioning plate 210, a guide post 220, a driving device 230, a first slider 240, a second slider 250, and a height measuring mechanism 260. A partition 120 is vertically arranged on the bottom plate 110 of the chassis 100. The positioning plate 210 and the guide post 220 are both vertically arranged on the bottom plate 110. The driving device is a lead screw motor, which provides more precise stroke. Fixed on the partition 120 of the laser screen removal machine, and with the driving direction, i.e. the length direction of the lead screw, perpendicular to the base plate 110, the first slider 240 is sleeved on the lead screw and the guide post 220, the second slider 250 is drivenly connected to the lead screw and sleeved on the guide post 220, the worktable 300 is fixedly connected to the second slider 250, the height measuring mechanism 260 is rotatably connected to the first slider 240, the positioning plate 210 is detachably provided with a positioning sensor 211, and the first slider 240 is provided with a sensor 241.

[0019] Because the reference plane of the laser focus is not on the same plane when each machine leaves the factory, the positioning plate 210 is provided with several positioning holes 212 for installing the positioning sensor 211. The position of the positioning sensor 211 can be selected according to the actual situation.

[0020] The first slider 240 and the second slider 250 move on the lead screw. Because of the obstruction of the base plate 110 and other structures, limit blocks 213 need to be set at both ends of the positioning plate 210 to limit the movement of the first slider 240 and the second slider 250 and avoid excessive movement.

[0021] A first side plate 130 is set on one side of the workbench 300. A fresh air deodorization device 131 is set on the first side plate 130. The deodorization device can be an ordinary adsorption deodorization fresh air machine or a plasma deodorization device.

[0022] It also includes a laser generator 400; the laser generator 400 is mounted on the partition 120, a reflector 500 is mounted above the laser generator 400, a galvanometer 600 is mounted on the side of the reflector 500, and a field mirror 700 is mounted below the galvanometer 600; directly below the field mirror 700 is the worktable 300, the mobile phone is placed on the worktable 300, the height measuring mechanism 260 is rotated onto the mobile phone, and the second slider 250 will move upward with the height measuring mechanism 260; the lead screw motor is started, the first slider 240 moves upward, taking the second slider 250 upward, until the second slider 250 senses the positioning sensor 211, the lead screw motor stops working, at this time the surface of the mobile phone on the worktable 300 is on the laser focal reference plane.

[0023] A guide rail 121 is provided on the other side of the partition 120 away from the laser generator 400. The guide rail 121 is slidably connected to the worktable 300, which can ensure that the worktable 300 runs more smoothly.

[0024] This invention utilizes the instantaneous heat generated by a laser to remove the paint layer behind the phone's outer screen, thus detaching it from the adhesive on the phone frame and allowing the phone screen assembly to be manually removed from the frame. Through the cooperation of the driving device 230, the first slider 240, the second slider 250, the height measuring mechanism 260, and the positioning sensor 211, the phone surface of different thicknesses is automatically positioned on the reference surface of the laser focal point.

[0025] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
