A display screen hot pressing device

Abstract

This utility model discloses a display screen hot pressing device, belonging to the field of hot pressing technology. The device includes a clamping assembly with a pair of symmetrical extension components in the middle. The key technical point is that a servo motor drives a worm gear to rotate, which in turn drives a worm wheel and a rotating shaft to rotate, causing the driving rod to rotate. This, in turn, drives a sliding block to slide on a mounting base plate via a driven rod, ultimately achieving the clamping action of the clamping block on the display screen. This design allows for flexible adjustment of the clamping block's position according to different display screen sizes, adapting to diverse production needs. Furthermore, the T-shaped sliding protrusion at the lower end of the sliding block cooperates with the T-shaped sliding groove on the mounting base plate, greatly enhancing the stability of the sliding block during sliding and effectively preventing it from shaking or shifting during hot pressing. This ensures precise positioning and firm fixation of the display screen, improving the accuracy of hot pressing and the yield rate of the product.

Description

Technical Field

[0001] This utility model relates to the field of hot pressing technology, and more specifically, to a display screen hot pressing device. Background Technology

[0002] Clamping is an essential step in the hot-pressing process of displays, mainly for the following reasons. First, the hot-pressing process requires applying a certain amount of pressure and temperature to the display. Without clamping and fixing, the display is prone to displacement under pressure. Once displacement occurs, the contact position between the display and other components will deviate, leading to problems such as display defects and uneven display, which seriously affects product quality and reduces yield.

[0003] However, current hot pressing devices for displays on the market have many shortcomings when performing hot pressing operations on displays. Some hot pressing devices have inadequate clamping structure designs, making it difficult to accurately position and fix displays of different sizes. Displays are prone to shifting during the hot pressing process, resulting in poor hot pressing effects and reduced product qualification rates. Furthermore, some hot pressing devices lack flexible expansion capabilities, failing to meet the placement and processing needs of displays of different specifications, limiting the equipment's applicability and increasing the cost of equipment replacement for companies.

[0004] Therefore, a display screen hot pressing device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a display screen hot pressing device, which drives the worm gear to rotate through a servo motor, thereby driving the worm wheel and the rotating shaft to rotate, causing the driving rod to rotate, and then driving the sliding block to slide on the mounting base plate through the driven rod, ultimately realizing the clamping action of the clamping block on the display screen. This design can flexibly adjust the position of the clamping block according to the display screen of different sizes.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0009] Furthermore, a driving rod is fixedly connected to the upper end of the rotating shaft, and driven rods are rotatably connected to both ends of the driving rod. A pair of driven rods are rotatably connected to sliding blocks at their ends that are far apart from each other. A pair of sliding blocks are slidably connected to the upper end of the mounting base plate. A clamping block is fixedly connected to the upper end of the pair of sliding blocks. An upper protective shell is fixedly connected to the upper end of the mounting base plate.

[0010] Furthermore, the extension component includes two pairs of connecting rods, which are fixedly connected to the front and rear ends of the mounting base plate, respectively, and a placement plate is fixedly connected between each pair of connecting rods.

[0011] Furthermore, a pair of T-shaped sliding protrusions are fixedly connected to the lower end of each pair of sliding blocks.

[0012] Furthermore, the upper end of the mounting base plate is provided with two pairs of T-shaped sliding grooves that are slidably connected to the T-shaped sliding protrusions.

[0013] Furthermore, the main body of the sliding block is C-shaped.

[0014] Furthermore, the main body of the clamping block is L-shaped.

[0015] In summary, this utility model has the following beneficial effects:

[0016] (1) This solution uses a servo motor to drive the worm gear to rotate, which in turn drives the worm wheel and the rotating shaft to rotate, causing the driving rod to rotate. Then, the driven rod drives the sliding block to slide on the mounting base plate, ultimately achieving the clamping action of the clamping block on the display screen. This design can flexibly adjust the position of the clamping block according to different sizes of display screens to adapt to diverse production needs. In addition, the T-shaped sliding protrusion at the lower end of the sliding block cooperates with the T-shaped sliding groove on the mounting base plate, which greatly enhances the stability of the sliding block during sliding and effectively prevents it from shaking or shifting during hot pressing. This ensures accurate positioning and firm fixation of the display screen, improves the accuracy of hot pressing and the yield rate of the product.

[0024] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0025] Reference Figures 1-4 As shown, a display screen hot pressing device is provided in a preferred embodiment of the present utility model, including a clamping component 1, and a pair of mutually symmetrical extension components 2 are provided in the middle of the clamping component 1.

[0026] The clamping assembly 1 includes a mounting base plate 101. A drive housing 102 is fixedly connected to the lower end of the mounting base plate 101. A rotating shaft 103 is rotatably connected to the middle of the mounting base plate 101. A worm gear 104 is fixedly connected to the lower end of the rotating shaft 103 and inside the drive housing 102. A servo motor 105 is fixedly connected inside the drive housing 102. A worm 106 is fixedly connected to the output end of the servo motor 105. The worm 106 meshes with the worm gear 104.

[0027] A driving rod 107 is fixedly connected to the upper end of the rotating shaft 103. Both ends of the driving rod 107 are rotatably connected to driven rods 108. A pair of driven rods 108 are rotatably connected to sliding blocks 109 at their far ends. Both sliding blocks 109 are slidably connected to the upper end of the mounting base plate 101. A clamping block 110 is fixedly connected to the upper end of both sliding blocks 109. An upper protective shell 111 is fixedly connected to the upper end of the mounting base plate 101.

[0028] This solution sets up a clamping assembly 1, which uses the meshing connection between the worm gear 106 and the worm wheel 104 at the output end of the servo motor 105 to drive the rotating shaft 103 to rotate, thereby causing the active rod 107 to rotate. The driven rods 108 at both ends of the active rod 107 drive the sliding block 109 to slide on the mounting base plate 101, thus achieving the effect of controlling the two clamping blocks 110 to move closer or further apart to clamp and release the display screen.

[0029] The extension component 2 includes two pairs of connecting rods 201, which are fixedly connected to the front and rear ends of the mounting base plate 101 respectively, and a placement plate 202 is fixedly connected between each pair of connecting rods 201.

[0030] A pair of T-shaped sliding protrusions are fixedly connected to the lower end of each pair of sliding blocks 109.

[0031] The upper end of the mounting base plate 101 has two pairs of T-shaped sliding grooves that are slidably connected to the T-shaped sliding protrusions.

[0032] The main body of the sliding block 109 is C-shaped.

[0033] The main body of the clamping block 110 is L-shaped;

[0034] This solution uses an L-shaped clamping block 110 to better fit the edge of the display screen, thereby clamping the display screen more stably and improving the reliability of clamping.

[0035] Specific implementation process: First, when it is necessary to clamp and fix the display screen, the servo motor 105 inside the drive housing 102 is started. The worm gear 106 at the output end of the servo motor 105 starts to rotate. Since the worm gear 106 is meshed with the worm wheel 104, the rotation of the worm gear 106 drives the worm wheel 104 to rotate, thereby causing the rotating shaft 103 fixedly connected to the worm wheel 104 to rotate synchronously. The driving rod 107 fixedly connected to the upper end of the rotating shaft 103 rotates accordingly. The driven rod 108 rotatably connected to both ends of the driving rod 107 swings under the drive of the driving rod 107. The sliding block 109 rotatably connected to the other end of the driven rod 108, because the T-shaped sliding protrusion at the lower end cooperates with the T-shaped sliding groove at the upper end of the mounting base plate 101, causes the sliding block 109 to slide linearly on the mounting base plate 101, ultimately driving the fixed connection of the sliding block 109 to rotate. The clamping block 110 moves towards the center to complete the clamping action of the display screen. By controlling the rotation direction and angle of the servo motor 105, the clamping block 110 can be released or the clamping force can be adjusted to adapt to the fixing requirements of different sized display screens. The two pairs of connecting rods 201 of the extension component 2 are fixed at the front and rear ends of the mounting base plate 101, respectively. The placement plate 202 is fixedly connected between each pair of connecting rods 201, providing additional placement space for display screens of different specifications. In actual production, for larger or special-sized display screens, part of them can be placed on the placement plate 202, which not only ensures the stability of the display screen during the hot pressing process, but also effectively utilizes the device space and meets diverse production needs. At the same time, the upper protective shell 111 protects the rotating parts inside the clamping component, prevents interference from external debris, and ensures the stable operation of the clamping component.
