Detailed Implementation

[0022] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0023] Example 1

[0024] A type of LCD screen strip pressing machine, such as Figures 1-5 As shown, the system includes a mounting plate 1, a conveyor belt 2, a backing plate 3, an electric slide rail 4, a sliding frame 5, a pressure frame 6, a guide rail 7, a pressure plate 8, a double-acting screw 9, a push block 91, an inclined plate 11, a contact rod 12, and a tension rope 13. Conveyor belts 2 are fixed to both sides of the mounting plate 1. Electric slide rails 4 are fixed to both the left and right sides of the rear of the mounting plate 1. A backing plate 3 is fixed between the middle of the two electric slide rails 4. A sliding frame 5 is slidably connected between the upper parts of the two electric slide rails 4. Pressure frames 6 are slidably connected to both sides of the sliding frame 5. Guide rails 7 are fixedly connected to both the front and rear sides of the middle section of the sliding frame 5. A pressure plate 8 is slidably connected to the middle of the guide rails 7. A double-acting screw 9 is rotatably connected to the top of the sliding frame 5. Push blocks 91 are threadedly connected to both the left and right sides of the double-acting screw 9. Push blocks 91 are slidably connected to the sliding frame 5. Push blocks 91 are pressed and engaged with the adjacent pressure frame 6. Inclined plates 11 are fixedly connected to both the front and rear sides of the upper part of the pressure frame 6. Contact rods 12 are fixedly connected to both the left and right sides of the top of the pressure plate 8. Inclined plates 11 are pressed and engaged with the adjacent contact rods 12. A tension rope 13 is fixedly connected between the pressure plate 8 and the adjacent guide rail 7.

[0025] like Figure 1 As shown, the conveyor belt 2 has longitudinally distributed blocks fixed to both the upper and lower sides.

[0026] like Figure 4 and Figure 5As shown, it also includes a limiting plate 10, a first spring 101, a connecting frame 102, and a sliding sleeve 103. The connecting frame 102 is slidably connected to both the front and rear sides of the middle of the electric slide rail 4. The first spring 101 is fixed between the connecting frame 102 and the electric slide rail 4. The sliding sleeve 103 is fixedly connected to both the front and rear sides of the pressure frame 6 near the adjacent electric slide rail 4. The connecting frame 102 is slidably connected to the adjacent sliding sleeve 103. The limiting plate 10 is fixedly connected between the front and rear connecting frames 102.

[0027] like Figure 4 As shown, the limiting plate 10 has a sloping surface on its front side.

[0028] When workers need to press the LCD screen and frame together, they can first align the LCD screen with the frame and place it on the conveyor belt 2. Then, according to the size of the LCD screen, the bidirectional screw 9 is rotated. If the LCD screen is large, the bidirectional screw 9 can be rotated in the forward direction, causing the push blocks 91, pressure frame 6, inclined plate 11, and connecting frame 102 on both sides to move in opposite directions. The first spring 101 is then stretched, and the inclined plates 11 on both sides, moving in opposite directions, will contact and squeeze the adjacent contact rod 12, thereby causing the contact rods 12 and pressure plate 8 on both sides to move in opposite directions. The tension rope 13 follows. If the LCD screen is small, the bidirectional screw 9 can be rotated in the reverse direction to move the push blocks 91 on both sides towards each other. The pressure frames 6, inclined plates 11, and connecting frames 102 on both sides will move towards each other under the action of the first spring 101, while the contact rods 12 and pressure plates 8 on the front and rear sides will move towards each other under the action of the tension rope 13. After adjustment, the LCD screen can be transported backward to a suitable position by the conveyor belt 2 and the abutment. However, since the precision of manually adjusting the bidirectional screw 9 is not high enough, the positions of the pressure frames 6 and pressure plates 8 are usually adjusted to be slightly smaller than the LCD screen. The position of the screen size is such that when the LCD screen moves backward, it contacts and presses against the limiting plate 10, causing the limiting plates 10 on the left and right sides, the pressure frame 6, and the inclined plate 11 to move in opposite directions. The first spring 101 is then stretched, and the contact rods 12 on the front and rear sides and the pressure plate 8 also move in opposite directions under the pressure of the inclined plate 11. The tension rope 13 is then stretched, and then the pressure frame 6 and pressure plate 8 can be moved downward by the electric slide rail 4 to press the LCD screen and the frame together. During this process, the abutment plate 3 supports the LCD screen and the frame, thus allowing for adaptability to different sizes of LCD screens to be assembled. Adjustments are made to ensure that the pressure frame 6 and pressure plate 8 can accurately press the LCD screen and the frame. After pressing, the pressure frame 6 and pressure plate 8 are moved upward and reset by the electric slide rail 4. Then, the LCD screen and frame are transported backward to the external collection device by the conveyor belt 2. At this time, the limiting plates 10, pressure frame 6, inclined plate 11 and connecting frame 102 on the left and right sides will move towards each other under the action of the first spring 101 until the pressure frame 6 contacts the push block 91. The contact rods 12 and pressure plate 8 on the front and rear sides will also move towards each other under the action of the tension rope 13 until the contact rod 12 contacts the inclined plate 11.

[0029] Example 2

[0030] Based on Example 1, such as Figure 5 and Figure 6 As shown, it also includes a guard plate 14 and a second spring 141. The guard plate 14 is slidably connected to the lower middle part of the sliding frame 5, and two second springs 141 are fixed between the guard plate 14 and the sliding frame 5.

[0031] like Figure 7 As shown, it also includes a wiping wheel 15 and a fan 16. The wiping wheel 15 is fixedly connected to the rear side of the mounting plate 1, and the fan 16 is fixedly connected to the rear side of the mounting plate 1.

[0032] When the electric slide rail 4 moves the pressure frame 6 and pressure plate 8 downwards, the guard plate 14 also moves downwards and presses against the LCD screen under the action of the second spring 141, thereby fixing and protecting the LCD screen and preventing it from shifting during pressing. When the electric slide rail 4 moves the pressure frame 6 and pressure plate 8 upwards to reset, the second spring 141 will first return to its original state and then move the guard plate 14 upwards to reset. When the conveyor belt 2 transports the LCD screen and frame backwards to the external collection device, the fan 16 can be started, and the fan 16 and wiping wheel 15 can be used to clean the dust and other impurities on the surface of the LCD screen, thereby ensuring the cleanliness of the LCD screen.

[0033] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
