[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] As Figures 1 to 4The illustrated screen front shell pressing device includes a device stand 100 with an operation window. The device stand 100 contains multiple contoured carrier plates 200 for placing products and a fixed plate frame assembly 300 located above the multiple contoured carrier plates 200. A first vertical limiting component 400 is provided on the fixed plate frame assembly 300. A movable plate assembly 500 is provided on the first vertical limiting component 400, limiting its vertical movement relative to the contoured carrier plates 200. The movable plate assembly 500... A second vertical limiting component 600 is provided, on which a contouring pressure head component 700 is provided to limit the vertical movement of the contouring carrier plate 200. A buffer elastic component is provided between the moving plate component 500 and the contouring pressure head component 700.

A pressure sensing mechanism 900 is provided between the pressing drive mechanism 800 and the moving plate component 500. In this specific embodiment, the pressure sensing mechanism 900 is a commercially available pressure sensor with a pressure gauge; the buffer elastic component consists of multiple commercially available springs. In practice, the pressing drive mechanism 800 drives the moving plate assembly 500 to move vertically relative to the multiple conforming carrier plates 200 on which the products are placed, under the limitation of the first vertical limiting component 400. The conforming pressure head assembly 700, under the limitation of the second vertical limiting component 600, is driven by the moving plate assembly 500 to move relative to the multiple conforming carrier plates 200 on which the products are placed, through the elastic force applied by the buffer elastic component, to press the products. Furthermore, the pressure sensing mechanism 900 ensures that the pressure magnitude meets the standard, guaranteeing the quality of product pressing. High-precision elastic pressing effectively improves the quality stability and efficiency of product pressing. A mating joint structure is provided between the pressing drive mechanism 800 and the pressure sensing mechanism 900. The mating joint structure includes a first joint 810 and a second joint 910. The upper end of the first joint 810 is connected and fixed to the lower end of the pressing drive mechanism 800 and is driven to move vertically by the pressing drive mechanism 800. The second joint 910 is fixed to the upper end of the pressure sensing mechanism 900 by bolts. The first joint 810 includes an internally threaded connecting post 811 connected to the pressing drive mechanism 800 and a mating limiting platform 812 protruding from the lower end of the internally threaded connecting post 811. The outer surface of the upper end of the internally threaded connecting post 811 is provided with a plurality of corresponding planes for the knob. One side of the second joint 910 is provided with a mounting groove 911 extending toward its center for the internally threaded connecting post 811 to pass through and a limiting groove 912 located below the mounting groove 911 for limiting the mating limiting platform 812.During disassembly and maintenance, simply unscrew the internal threaded connecting post 811 from the lower end of the pressing drive mechanism 800, and then slide the internal threaded connecting post 811 and the mating limit table 812 out of the mounting groove 911 and the limit groove 912 respectively to complete the disassembly of the pressing drive mechanism 800 and the pressure sensing mechanism 900, thus making room for subsequent component disassembly. Installation, disassembly, and maintenance are convenient.

[0019] Based on the above, as shown in the figure Figure 1 and Figure 2 As shown, the fixed plate frame assembly 300 includes multiple horizontal fixed plates 310 located above multiple contoured carrier plates 200 and multiple sets of fixed columns 320 for fixing the multiple horizontal fixed plates 310. The first vertical limiting assembly 400 includes multiple sets of first vertical limiting structures respectively disposed on the multiple horizontal fixed plates 310. The moving plate assembly 500 includes multiple moving plates respectively disposed on the multiple sets of first vertical limiting structures, which limit their vertical movement. The second vertical limiting assembly 600 includes multiple sets of second vertical limiting structures respectively disposed on the multiple moving plates. The contouring pressure head assembly 700 includes multiple contouring pressure heads respectively disposed on the multiple sets of second vertical limiting structures, which limit their vertical movement relative to the multiple contoured carrier plates 200. The vertical relative movement of the multiple contouring pressure heads is independently limited, resulting in minimal mutual interference during long-term operation and ensuring the stability and accuracy of multi-position pressing.

[0020] Based on the above, such as Figure 1 and Figure 2 As shown, the pressing drive mechanism 800 includes multiple linear drive mechanisms, each used to drive multiple moving plates to move vertically. In this specific embodiment, the linear drive mechanism is a cylinder assembly with controllable stroke. In actual implementation, the linear drive mechanism can also be a hydraulic cylinder assembly or other linear drive mechanism, depending on the actual stroke, accuracy, and pressure. Multiple linear drive mechanisms independently drive the moving plates, ensuring no interference between the various pressing structures and resulting in more stable operation.

[0021] Based on the above, such as Figure 1 As shown, the equipment platform 100 is equipped with multiple sets of control buttons for operating multiple linear drive mechanisms. In this specific embodiment, each set of control buttons includes a dual start button and an emergency stop button located in the direction corresponding to the linear drive mechanism. Multiple linear drive mechanisms are operated independently. When one linear drive mechanism fails, the others can still be used. The faulty mechanism can be repaired at an appropriate time, avoiding overall downtime caused by a single component, thus ensuring more stable production capacity.

[0022] Based on the above, such as Figure 1 and Figure 2As shown, the operating window on the equipment platform 100 is equipped with multiple sets of safety light curtains 110, each corresponding to a different movement range of a moving plate. This provides good safety performance.

[0023] Based on the above, such as Figure 1 and Figure 2 As shown, the first vertical limiting structure includes multiple sets of first flange bearings 410 and first slide rods 420 used in conjunction, and the second vertical limiting structure includes multiple sets of second flange bearings 610 and second slide rods 620 used in conjunction. The simple structure achieves vertical limiting.

[0024] Based on the above, such as Figure 3 As shown, the periphery of the product placed on the conformal carrier plate 200 is provided with multiple pressing guide alignment posts 210. The conformal press head has alignment guide holes 711 at positions corresponding to the pressing guide alignment posts 210, with an inner diameter identical to the outer diameter of the pressing guide alignment posts 210. The upper end of the pressing guide alignment post 210 has a smooth guide arc surface, and the lower end of the alignment guide hole 711 has an outwardly expanding guide arc surface. During the pressing process, high-precision alignment and limiting, as well as guidance, prevent jamming and ensure proper pressing.

[0025] Based on the above, such as Figure 3 As shown, the periphery of the product placed on the conforming carrier plate 200 is provided with multiple travel limit blocks 220 for limiting the pressing displacement distance of the conforming pressure head. These limit the pressing limit distance of the conforming pressure head to prevent damage to the pressed product due to excessive pressing force caused by malfunction.

It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model.
