[0030] like Figure 1 and Figure 2 As shown, a pneumatic iPad screen pressing fixture includes a base 100, a fixing module 200, a support 300, a cylinder 400, and a pressing assembly 500; the fixing module 200 is fixed to the top of the base 100 and is used to fix the iPad screen.
[0031] The support member 300 is vertically connected to the top of the base 100, and a guide shaft 301 is fixed between the support member 300 and the base 100;
[0032] Cylinder 400 is mounted on the side of support 300, and its output end extends downward and is connected to pressing assembly 500;
[0033] The pressing assembly 500 includes a pressure plate 501, on which a linear bearing 504 is mounted. The linear bearing 504 is slidably engaged with a guide shaft 301, driving the pressing assembly 500 to move axially along the guide shaft 301 to perform the pressing operation. The engagement between the guide shaft 301 and the linear bearing 504 ensures that the movement trajectory of the pressing assembly 500 is always perpendicular, avoiding the skewing problem caused by the lack of a guiding structure in traditional fixtures. The cylinder 400 makes the pressing process smoother, reduces errors from manual operation, and improves production efficiency and product yield.
[0034] like Figure 2 and Figure 3 As shown, the fixing module 200 includes a support plate 201, which is fixed to the top of the base 100. The top surface of the support plate 201 is provided with a receiving groove 202 that matches the shape of the iPad screen. The shape matching design of the receiving groove 202 enables the iPad screen to be placed quickly and accurately, reducing adjustment time.
[0035] like Figure 2 and Figure 3 As shown, limit blocks 203 are fixedly connected to the four corners of the top of the support plate 201, and the four limit blocks 203 are distributed at the four corners of the receiving groove 202.
[0036] Limiting strips 204 are fixedly connected to both the front and rear sides of the top of the support plate 201. The limiting strips 204 are arranged along the length direction of the receiving groove 202 and are located between two limiting blocks 203 to limit the displacement of the iPad screen. The limiting blocks 203 and the limiting strips 204 form a circumferential limit on the iPad screen, which can prevent the screen from shifting or warping during the pressing process and ensure the accuracy of the pressing position.
[0037] like Figure 2 and Figure 3 As shown, the bottom of the receiving slot 202 is provided with a relief slot 205. The position of the relief slot 205 corresponds to the interface area of the iPad screen, so as to avoid interference with the interface during the pressing process and protect the interface structure of the iPad screen.
[0038] like Figure 4 and Figure 5 As shown, corner blocks 502 are fixedly connected to the four corners of the bottom of the pressure plate 501, and edge strips 503 are fixedly connected to the front and rear sides of the pressure plate 501. The edge strips 503 are set along the length of the pressure plate 501 and are located between the two corner blocks 502, so as to apply pressure evenly to the four corners and edges of the screen.
[0039] like Figure 2 and Figure 5As shown, the top of the base 100 is provided with at least two positioning holes 101, and the bottom of the pressure plate 501 is provided with a corresponding positioning rod 505. The positioning rod 505 is coaxially engaged with the positioning hole 101 and is used to calibrate the pressing position of the pressure plate 501. During the pressing process, the positioning rod 505 will be inserted into the positioning hole 101, and the movement trajectory of the pressure plate 501 will be completely aligned with the receiving groove 202 of the fixing module 200.
[0040] like Figure 1 and Figure 4 As shown, a mounting plate 506 is fixedly connected to the top of the pressure plate 501. The mounting plate 506 is fixedly connected to the output end of the cylinder 400, which facilitates the installation of the pressing assembly 500.
[0041] The bottom surface of the corner block 502 and the edge strip 503 is provided with an elastic buffer layer. The elastic buffer layer is made of silicone or rubber and is bonded to the bottom surface of the corner block 502 and the edge strip 503. The elastic buffer layer can effectively absorb the impact energy during the pressing process, prevent the brittle cracking or scratches of the screen corners, and improve the stability of the pressing process and the finished quality of the screen.
