Description

Technical Field

[0001] This utility model relates to the field of external module technology, and in particular to a bonding TP fixture for external modules. Background Technology

[0002] Touch panel fixtures are mainly used in the bonding process between add-on modules and touch panels (TPs) in products such as mobile phones, tablets, and smart wearable devices. By optimizing the fixture structure and function, the problems of low bonding accuracy, poor efficiency, and insufficient compatibility of existing bonding fixtures are solved, achieving efficient and precise bonding between add-on modules and TPs, thereby improving product manufacturing quality and efficiency.

[0003] In existing technologies, traditional bonding fixtures mostly rely on manual alignment. Due to the subjectivity and error of human operation, it is difficult to achieve precise alignment between the external module and the TP, resulting in problems such as misalignment and air bubbles after bonding, which affects the display effect and touch performance of the product. It is also easy to apply the module crookedly during bonding because there is looseness during the bonding process, resulting in poor bonding effect. Therefore, we propose a bonding fixture for external modules to TP. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] refer to Figure 1-6A bonding TP fixture for an external module includes a fixing plate, a workpiece placement rack, a fixing frame, and a moving box. The system includes four supporting columns, located at the four corners of the fixed plate; a workpiece placement rack, located some distance away from the fixed plate from each of the supporting columns; a fixed frame, located on the fixed plate, having an internal movable cavity; a threaded rod, located on the fixed frame; a first knob, located at one end of the threaded rod; a movable box, located at the end of the threaded rod away from the first knob, located within the movable cavity of the fixed frame; two movable slots, located on the workpiece placement rack; a sliding slot, located on one side of the workpiece placement rack; and a through slot, located on one side of the fixed frame. The touch panel to be fitted is placed above the workpiece placement rack 3, and the first knob 5 is controlled according to the size of the touch panel to rotate the threaded rod 4. After rotation, the threaded rod 4 can move the movable box 6 through threaded engagement, adjusting the position of the clamping plate 18. In this embodiment, a lead screw 11 is rotatably mounted on the inner side of the movable box 6, and the lead screw 11 is slidably located inside the through slot 10. A second knob 12 is fixedly mounted on the front side of the lead screw 11.

[0027] In this embodiment, the device further includes: a movable slider disposed on the lead screw, the movable slider being threadedly connected to the lead screw; and multiple fixed cylinders disposed on the movable slider and the movable box, respectively. In this embodiment, a spring 15 is fixedly installed on the inner wall of one side of the fixed cylinder 14, a movable block 16 is fixedly installed on the outer side of one end of the spring 15, a slide rod 17 is fixedly installed on one side of the movable block 16, and a clamping clamp plate 18 is fixedly installed on one side of the slide rod 17. After the clamping clamp plate 18 abuts against the touch panel, it can be moved by the cooperation of the spring 15 and the movable block 16, thereby ensuring that the clamping clamp plate 18 is always in contact with the touch panel. Multiple clamping clamp plates 18 can make the touch panel more stable during the clamping process.

[0028] In this embodiment, it further includes: two guide rods, respectively disposed inside the fixed frame; two guide blocks, disposed at one end of each guide rod; and a moving block disposed at the end of the guide rod away from the guide block. In this embodiment, the width of the through groove 10 is greater than the diameter of the lead screw 11, and the width of the sliding groove 9 is greater than the diameter of the fixed cylinder 14. The second knob 12 is controlled to drive the lead screw 11 to move. After the lead screw 11 rotates, it can drive the moving slider 13 to move through the threaded engagement, which can adjust the contact pressure between the clamping plate 18 and the touch panel to prevent damage due to excessive pressure. The moving groove 8, the sliding groove 9, and the through groove 10 can make the movement of multiple structures more stable and make the clamping plate 18 fit more closely to the touch panel.

[0029] In this embodiment, the workpiece placement rack 3 has a rubber pad inside, and the side of the clamping plate 18 has an anti-slip pad. The anti-slip pad and the rubber pad work together to prevent the touch panel from being damaged by collision during clamping, thus ensuring high safety. In this embodiment, a through hole is opened on one side of the fixed cylinder 14, the slide rod 17 fits into the through hole, and the outer diameter of the moving block 16 is larger than the inner diameter of the through hole. The through hole facilitates the slide rod 17 to move the clamping plate 18, while the moving block 16 prevents the slide rod 17 from detaching from the inside of the fixed cylinder 14.

[0030] The implementation principle of the TP bonding fixture for an external module in this embodiment is as follows: The touch panel to be bonded is placed above the workpiece placement rack 3. Based on the size of the touch panel, the first knob 5 is controlled to rotate the threaded rod 4. After rotation, the threaded rod 4 can move the movable box 6 through threaded engagement, adjusting the position of the clamping plate 18. The second knob 12 is then controlled to move the lead screw 11. After rotation, the lead screw 11 can move the movable slider 13 through threaded engagement, adjusting the clamping fixture. The contact pressure between plate 18 and the touch panel prevents damage due to excessive pressure. The moving groove 8, sliding groove 9 and through groove 10 allow multiple structures to move relatively stably and ensure that the clamping plate 18 fits closely to the touch panel. After the clamping plate 18 abuts against the touch panel, it can be moved by the cooperation of spring 15 and moving block 16, thus ensuring that the clamping plate 18 is always in contact with the touch panel. Multiple clamping plates 18 can make the touch panel more stable during the clamping process.
