Description

A positioning fixture for hot-press bonding of mobile phone screens Technical Field

[0001] This utility model belongs to the field of mobile phone screen clamping technology, and in particular relates to a positioning clamp for hot pressing and bonding of mobile phone screens. Background Technology

[0002] In recent years, the rapid popularization of smartphones has driven the growth of the global mobile phone screen market and accelerated technological innovation, leading to a continuous increase in industry scale. In terms of product composition, current mobile phone screens are mainly touchscreens, consisting primarily of cover glass, touch modules, and display modules. However, with the increasing demands for thinner and lighter mobile phones and higher-definition displays, as well as the growing maturity of embedded touch technology, the mobile phone screen industry is gradually shifting from traditional single-component supply to integrated module production, with a clear trend towards vertical integration of the industry chain.

[0003] In the production of mobile phone screens, components such as touch modules and display modules need to be bonded together by hot pressing. In this process, the screen needs to be clamped first and then bonded. During the clamping process, the position of the mobile phone screen may shift from the center position of the hot pressing bonding device, resulting in uneven force on the screen, which affects the bonding efficiency and product quality. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a positioning fixture for hot pressing and bonding of mobile phone screens, which can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a positioning fixture for hot pressing and bonding of mobile phone screens, including: a base, side plates fixed on both sides of the base, a movable bracket installed on one side of the base, connecting brackets installed on both sides of the movable bracket, a fixed bracket installed inside the side plates, and a fixture connected to one side of the fixed bracket.

[0007] It also includes: the side plates fixed on both sides of the base have grooves with bevels inside, and the size of the grooves allows the fixing frame to move inside the side plates along the direction of the grooves;

[0008] Two sets of waist-shaped slots are opened on both sides of the movable bracket, and a limit is provided at the top of the waist-shaped slot on the movable bracket. A waist-shaped slot that matches the two sides of the movable bracket is opened on one side of the connecting frame, and a limit is provided at the bottom of the slot on the connecting frame that corresponds to the movable bracket.

[0009] Furthermore, a set of cylinders is installed on one side of the base, and a piston rod is provided inside the cylinder. The movable bracket is connected to the piston rod through a slot on one side.

[0010] Furthermore, the top of the movable bracket is provided with a set of threaded holes, and the top of the limiting block is provided with an oblong groove. The limiting block is installed on the movable bracket by means of a threaded connection between the positioning bolt and the movable bracket.

[0011] Furthermore, a set of grooves is provided on one side of the base, and a cylinder is fixed inside the grooves. A round hole is provided in the middle part of the rocker plate to cooperate with the cylinder in the groove of the base. The rocker plate is rotatably connected to the cylinder in the base through the round hole.

[0012] Furthermore, the movable bracket and the connecting frame are connected by a connecting slider. The top and bottom of the connecting slider are respectively installed inside the waist-shaped slots on the movable bracket and the connecting frame, so that the movable bracket and the connecting frame are connected by transmission through the connecting slider.

[0013] Furthermore, two sets of rollers are installed on both sides of the connecting slider, allowing the connecting slider to move along the direction of the waist-shaped slot on the movable bracket and connecting frame.

[0014] This utility model has the following beneficial effects: By setting matching waist-shaped slots on both sides of the movable bracket and one side of the connecting frame, and using connecting sliders installed inside both the movable bracket and the connecting frame, the piston rod driven by the cylinder pushes the movable bracket, causing the connecting sliders to move simultaneously inside both the movable bracket and the connecting frame. This enables the connecting frame to move in the direction of the movable bracket. The fixed frame fixed on the other side of the connecting frame allows the fixed frame to move along the direction of the groove on the side plate. When the limiting block positions the workpiece, the two sets of clamps installed on the two sets of fixed frames clamp the workpiece, which effectively solves the problem of the workpiece not being in the center of the device during clamping, and reduces the problem of uneven force on the screen affecting product quality.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please refer to Figures 1-4. This utility model is a positioning fixture for hot-press bonding of mobile phone screens, including: a base 1, side plates 2 fixed on both sides of the base 1, a movable bracket 3 installed on one side of the base 1, connecting brackets 4 installed on both sides of the movable bracket 3, a fixing bracket 5 installed inside the side plates 2, and a clamp 6 connected to one side of the fixing bracket 5; it also includes: two sets of side plates 2 fixed on both sides of the base 1, with grooves with bevels opened inside the side plates 2, and the size of the grooves allows the fixing bracket 5 to move inside the side plates 2 along the direction of the grooves, and the movable bracket 3... The movable support 3 is installed inside the track opened on the base 1, allowing it to move along the track opening direction. A set of cylinders 10 is installed on one side of the base 1. The cylinders 10 have piston rods inside. One side of the movable support 3 is connected to the piston rod of the cylinders 10. The movable support 3 can be moved by driving the cylinders 10. A set of threaded holes is also opened on the top of the movable support 3. The limiting block 7 is installed on the top of the movable support 3 by opening threaded holes that cooperate with the positioning bolts 9 and using the threaded connection between the positioning bolts 9 and the threaded holes on the top of the movable support 3. Two sets of waist-shaped slots are respectively opened on both sides of the movable bracket 3, and a limit is provided at the top of the waist-shaped slot of the movable bracket 3. A waist-shaped slot that matches the two sides of the movable bracket 3 is opened on one side of the connecting frame 4, and a limit is provided at the bottom of the slot of the connecting frame 4 that corresponds to the one on the movable bracket 3. The top and bottom of the connecting slider 8 are respectively installed inside the slots opened on the movable bracket 3 and the connecting frame 4. The limit inside the slots allows the connecting slider 8 to connect the movable bracket 3 and the connecting frame 4. Two sets of rollers are installed on both sides of the connecting slider 8, allowing the connecting slider 8 to move along the opening direction of the waist-shaped slots on the movable bracket 3 and the connecting frame 4. The size of the connecting slider 8 is designed so that the connecting slider 8 can move simultaneously in the two sets of waist-shaped slots. A set of grooves is opened on one side of the base 1, and a cylinder is fixed inside the grooves. A round hole that matches the cylinder in the groove of the base 1 is opened in the middle part of the rocker plate 11. The rocker plate 11 is rotatably connected to the cylinder in the base 1 through the round hole.

[0024] During processing, the mobile phone screen to be processed is first placed on the rocker plate 11. Then, the cylinder 10 drives the moving bracket 3 to move along the groove on the bottom base 1 of the moving bracket 3. When the piston rod pushes the moving bracket 3, the connecting slider 8 inside the moving bracket 3 moves simultaneously along the moving direction of the moving bracket 3. When the connecting slider 8 moves to the limit position in the slot on the connecting frame 4, the connecting slider 8 can continue to move along the direction of the slots on both sides of the moving bracket 3, driving the connecting frame 4 to move simultaneously along the moving direction of the moving bracket 3. A fixing frame 5 is fixed on the other side of the connecting frame 4, so that the fixing frame 5 moves along the groove on the side plate 2. A clamp 6 is also installed on the other side of the fixing frame 5. The simultaneous movement of the two sets of clamps 6 can clamp the mobile phone screen. By the inward movement of the limiting block 7 and the two sets of clamps 6, the screen can be clamped while being positioned, so that the mobile phone screen is always in the center position of the device, so that the hot pressing bonding device above can process it. After processing is completed, the cylinder 10 is driven again to retract the moving bracket 3. During the retraction of the moving bracket 3, the connecting slider 8 first moves with the moving bracket 3 to another limit position in the connecting frame 4, and then pulls the connecting frame 4 and the moving bracket 3 to move simultaneously, so that the fixed frame 5 moves along the groove direction again, so that the distance between the two sets of clamps 6 increases and no longer clamps. Then, using the pressure plate fixed on one side of the rocker 11, the rocker 11 can be lifted by simply pressing the pressure plate, making it easier to remove the mobile phone screen.
