Description

Technical Field

[0001] The utility model belongs to the technical field of liquid crystal touch module lamination, and in particular relates to a positioning jig for producing liquid crystal touch modules. Background Art

[0002] ‌LCD touch screen, also known as touch panel, is an inductive liquid crystal display device that can receive input signals such as contacts‌. When the user touches the graphic button on the screen, the tactile feedback system on the screen can drive various connection devices according to the pre-programmed program, thereby replacing the mechanical button panel and creating vivid audio and video effects through the LCD display. LCD touch screen has the advantages of being light, taking up little space, and being convenient and flexible. It has gradually replaced keyboards and become a commonly used human-computer interaction tool for embedded systems. Touch screens can be divided into five categories according to their technical principles, among which resistive touch screens are more commonly used in embedded systems. With the growing demand for multimedia information query, touch screens have been widely used in many fields, such as public information query, industrial control, multimedia teaching, etc., due to their advantages such as ease of use, durability, fast response speed, and space saving;

[0003] After searching, the application (publication) number is: CN114801422A, which discloses: a touch screen assembly fitting and positioning jig, "including a frame, the inner side of the frame is connected to the base through an integral mold, a placement plate is provided above the base, a positioning mechanism is provided on the inner side of the top end of the frame and extends to the interior of the frame, the positioning mechanism includes a push block, a push block, a movable rod, and a movable plate, the push block is slidably connected to the outer wall of one end of the frame through a slide groove and a slider and extends through the frame to the interior of the base" and other technical features, with "by setting the positioning mechanism, compared with the traditional fitting jig, which needs to manually adjust the inner diameter of the jig to match the outer wall of the screen assembly, this structure can automatically match the size of the outer wall of the screen assembly to limit the screen assembly, and after the screen assembly is taken out, the fitting jig can be reset again, reserving sufficient space to facilitate the placement and positioning of the next screen assembly, thereby further improving the placement efficiency of the screen assembly" and other technical effects;

[0004] In actual use, it was found that because the device needs to leave space for the "movable plate" and "block" to move, and to ensure clamping reliability, the "block" needs to have a certain width, which greatly reduces the area available for the "placement plate". The stability of the touch module during assembly is also reduced. In addition, after the module components are fitted together to ensure tightness, pressure needs to be applied. Due to the small contact area, the pressure generated increases, which can easily damage the module or cause the module to deform due to downward pressure. The glue then solidifies, causing the finished product to deform and become scrapped.

[0005] To solve the above problems, this application proposes a positioning fixture for producing liquid crystal touch modules. Utility Model Content

[0030] See also Figure 1-6 As shown, the utility model is a positioning jig for producing liquid crystal touch modules, comprising a laminating jig table 1, a positioning component 2 is provided on the laminating jig table 1, and a pressing component 3 is further provided between the laminating jig table 1 and the positioning component 2; the positioning component 2 comprises a positioning plate 21 sliding on the upper surface of the laminating jig table 1 and an internal thread block 22 fixed to the bottom of the positioning plate 21, and a screw 23 rotating inside the laminating jig table 1 and threadedly engaged with the internal thread block 22; the pressing component 3 comprises a rotating plate 31 rotatably provided on the positioning plate 21 and a pressing rod 32 fixed away from the hinged end of the rotating plate 31, and The local gear 33 is coaxial with the hinge of the rotating plate 31 and the positioning plate 21, and also includes a tooth plate 34 that is perpendicular to the bonding jig table 1 and meshes with the local gear 33. In this embodiment, through the mutual cooperation between the bonding jig table 1 and the positioning component 2 and the pressing component 3, the bonding jig table 1 provides a reliable placement surface to avoid deformation of the touch module caused by pressing. The positioning component 2 can flexibly position or release the touch module placed on the bonding jig table 1. The pressing component 3 can be adjusted synchronously with the adjustment of the positioning component 2, and can provide stable and uniform downward pressure after adjustment, thereby ensuring the consistency and quality of the finished product.

[0031] Among them, a lifting plate 35 is fixed to the outside of the tooth plate 34, a sliding sleeve 36 is fixed to the bottom of the lifting plate 35, and a sliding seat 37 parallel to the screw 23 is provided at the bottom of the fitting jig table 1. In this embodiment, by setting the cooperation between the sliding sleeve 36 and the sliding seat 37, it can provide a movable space in the horizontal direction while being fixed in the vertical direction, thereby ensuring the vertical transmission stability while adapting to the horizontal adjustment of the positioning plate 21 on the fitting jig table 1.

[0032] Among them, a number of guide rods 38 are fixed at the bottom of the bonding jig table 1, and the slide 37 is fitted on the outside of the guide rods 38 and slides vertically. An electric cylinder 39 is fixed under the bonding jig table 1 to drive the slide 37 to slide on the outside of the guide rods 38. A connecting frame 310 is fixed between the output end of the electric cylinder 39 and the slide 37. In this embodiment, the guide rods 38 ensure the linear movement of the slide 37, the lifting plate 35, and the tooth plate 34, thereby ensuring the reliable engagement of the local gear 33 with the tooth plate 34.

[0033] Among them, the internal thread block 22 is fixed with a limit frame 311 on the side close to the tooth plate 34, and the lifting plate 35 slides in the limit frame 311 on the side away from the tooth plate 34. In this embodiment, the limit frame 311 limits the lifting plate 35 away from the tooth plate 34, thereby ensuring the meshing stability between the tooth plate 34 and the local gear 33.

[0034] Among them, the lifting plate 35 is provided with an avoidance groove 312 that cooperates with the screw 23 on the side close to the sliding sleeve 36. In this embodiment, the avoidance groove 312 can ensure the stable cooperation between the local gear 33 and the tooth plate 34 without affecting the cooperation between the internal thread block 22 and the screw 23.

[0035] Among them, the pressing component 3 also includes a driven wheel 24 fixed at one end of the screw 23, and a driving wheel 25 that engages with the driven wheel 24 is rotated at the bottom center of the bonding jig table 1. In this embodiment, the screw 23 and the driven wheel 24 are multiple groups distributed in a circle, and multiple driven wheels 24 engage with the same driving wheel 25 at the same time, thereby realizing the synchronous movement of multiple positioning plates 21 on the bonding jig table 1, thereby improving controllability and consistency.

[0036] Among them, a motor 26 is installed at the bottom of the bonding jig table 1, and a belt transmission group 27 is also provided between the output end of the motor 26 and the driving wheel 25. In this embodiment, the motor 26 is installed at the side position of the bottom of the bonding jig table 1 through the belt transmission group 27, which can leave enough installation space for the electric cylinder 39 without affecting the transmission, reduce the overall jig height, and make the structural distribution more reasonable.

[0037] It can be understood that through the mutual cooperation between the bonding jig table and the positioning components and the pressing components, the bonding jig table provides a reliable placement surface to avoid deformation of the touch module caused by pressing. The positioning components can flexibly position or release the touch module placed on the bonding jig table. The pressing components can be adjusted synchronously with the adjustment of the positioning components, and can provide stable, uniform and precise downward pressure after adjustment, thereby ensuring the consistency and quality of the finished product.

[0038] A specific application of this embodiment is as follows: the module component to be bonded is placed on the bonding jig table 1, and the motor 26 and the belt transmission group 27 drive the driving wheel 25 to engage with the driven wheel 24, and drive the screw 23 and the internal thread block 22 to generate a spiral, thereby driving the positioning plates 21 in four directions to move inward synchronously until the module component is positioned. During the adjustment process of the positioning component 2, the sliding sleeve 36 follows the movement of the internal thread block 22 and slides outside the sliding seat 37, and the toothed plate 34 and the lifting plate 35 on the sliding sleeve 36 also move accordingly;

[0039] After the bonding process, the output end of the electric cylinder 39 drives the slide 37 to move upward through the connecting frame 310. At this time, the slide 37 slides outside the guide rod 38, the sliding sleeve 36, the lifting plate 35, and the toothed plate 34 move upward, and the avoidance groove 312 moves upward outside the screw rod 23. The toothed plate 34 meshes with the local gear 33 and drives the rotating plate 31 and the pressure rod 32 to rotate toward the touch module until the pressure rod 32 presses the module into shape.

[0040] After the pressing is completed, the pressing part 3 is reset to Figure 1-2 In the state shown, the positioning component 2 is loosened and the formed touch module can be removed.
