Description

Technical Field

[0001] This utility model relates to the field of automation technology, and in particular to a clamping and positioning device for an intelligent screen removal machine. Background Technology

[0002] With the advancement of technology, electronic products have developed rapidly. For example, smartphones have gradually transitioned from small, portable devices to full-screen phones with increasingly larger screens and foldable phones with even greater thickness. Furthermore, modern phones are increasingly designed with dustproof and waterproof features, placing higher demands on the integrity and sealing of the phone. This has increased the difficulty of disassembly during phone repair.

[0003] Currently, smartphone panels and rear battery covers are primarily secured with adhesive. During disassembly, the panel must be heated to 65°C to degrade the adhesive before being removed and replaced using a suction cup. However, conventional phone clamping heating platforms typically only heat the bottom of the phone, resulting in a prolonged heating time and reduced disassembly efficiency. Therefore, improvements are needed. Utility Model Content

In one embodiment, it includes a mounting base plate 1; a lifting drive mechanism 2 is mounted on the mounting base plate 1, and the lifting drive mechanism 2 is driven and connected to a lifting plate 21; a support plate 22 for placing products is mounted on the lifting plate 21, and a lower heating component is also installed inside the support plate 22; a left and right clamping mechanism 3 is also mounted on the mounting base plate 1, and the left and right clamping mechanisms 3 are driven and connected to two side clamping seats 4; the two side clamping seats 4 are respectively arranged on one side of the support plate 22, and the two side clamping seats 4 are aligned with each other. A side heating assembly is installed on each side; the left and right clamping mechanisms 3 are used to drive the two side clamping seats 4 to move closer or further away from each other; an end clamping mechanism 5 is also installed on the mounting base plate 1, and the end clamping mechanism 5 is also driven to connect to an end clamping seat 6; the end clamping seat 6 is arranged near one end of the support plate 22, and an end fixing seat 7 is also provided at the other end of the top of the mounting base plate 1 near the support plate 22; an end heating assembly 71 is installed on each side opposite to the end fixing seat 7 and the end clamping seat 6, and the end clamping mechanism 5 is used to drive the end clamping seat 6 to move closer or further away from the end fixing seat 7.

[0025] Continue to refer to Figures 1 to 6As shown, in this embodiment, the lower heating component, the side heating component, and the end heating component 71 all include heating tubes and temperature-sensing thermocouples, which can heat the front, back, left, right, and bottom of the mobile phone. The heating is uniform, which can ensure that the product can heat up quickly to make the adhesive fail, so as to carry out the next screen removal process. This greatly saves the product heating time. With temperature-sensing thermocouples, closed-loop temperature control can be achieved, which improves the safety of heating. At the same time, a vacuum pump, a solenoid valve, and a filter are also installed on the mounting base plate 1, which can provide an air source for the screen removal machine's disassembly mechanism, so that the screen removal machine does not need an external air source, making it convenient to transport and suitable for various occasions that require maintenance.

[0026] In this embodiment, both the side heating assembly and the end heating assembly 71 further include a heating seat. The heating seat is detachably installed on one side of the side clamping seat 4, the end clamping seat 6, or the end fixing seat 7. The heating tube and the temperature measuring thermocouple are installed inside the heating seat. The following description takes the installation of the heating seat on the end clamping seat 6 as an example (the heating seat installed on the end clamping seat 6 or the end fixing seat 7 is similar). Refer to Figure 1 As shown, an installation step is provided on one side of the end clamping seat 6. The heating seat has an overall L-shaped structure. The horizontal end of the L-shaped heating seat is arranged on the installation step, and the vertical end of the L-shaped heating seat is arranged downward. At the same time, a locking hole is provided on the horizontal end of the L-shaped heating seat. A screw is locked into the locking hole, so the heating seat can be quickly installed on the end clamping seat 6. At the same time, when disassembling the heating seat, simply loosen the screw and remove it for replacement. It is simple and efficient.

[0027] Furthermore, in this embodiment, a first bracket 12 is installed on each side of the top of the mounting base plate 1 near the end fixing seat 7; the two first brackets 12 are arranged opposite to each other, and a pair of optical fibers 13 are installed on each first bracket 12. Through the optical fibers 13, the accuracy of the product being lifted into place can be ensured. During operation, the product to be disassembled is first placed on the carrier plate 22. Then, the left and right clamping mechanisms 3 drive the two side clamping seats 4 to move closer to each other to clamp the product in the center. Then, the left and right clamping mechanisms 3 drive the two side clamping seats 4 to retract to their original positions, and the lifting drive mechanism 2... The lifting plate 21 is driven to rise so that the product is raised to the position sensing position of the through-beam 13. Then, the end clamping mechanism 5 drives the end clamping seat 6 to move towards the end fixing seat 7 to push the product to the end fixing seat 7 and cooperate with the two side clamping seats 4 to clamp and fix the product. Finally, the disassembly mechanism of the screen removal machine presses down on the product to press and fix it. Then, the clamping and positioning device heats the left, right, front, back and bottom of the product, and the disassembly mechanism heats the top of the product to make the product quickly heat up to the required temperature. Finally, the disassembly mechanism removes the screen or back cover of the product.

The support plate 22 is floatingly connected to the lifting plate 21 via the first spring 212, which can accommodate the disassembly of mobile phones that are warped and uneven, and has strong compatibility.

At the same time, both the end clamping motor 51 and the lifting motor adopt stepper servo motors. When clamping, the clamping torque feedback stops and the position is confirmed. It can be compatible with various products and has high compatibility.
