[0002] A touch screen, also known as a touch panel, is an inductive liquid crystal display device that can receive input signals such as touches. When a graphic button on the screen is touched, the tactile feedback system on the screen can drive various connecting devices according to a pre-programmed program, which can be used to replace a mechanical button panel to achieve a more convenient and fast interface operation. Due to its excellent display and operation performance, the touch screen is often used as the operation and display unit of intelligent devices and is widely used on the upper part of intelligent mobile devices. In terms of structure, the touch screen is mostly connected and installed as an independent screen module with the intelligent workpiece body. When assembling the touch screen, the touch screen needs to be accurately bonded and installed with the workpiece body. In order to ensure the bonding and installation accuracy of the screen body and the workpiece body, a positioning jig is required to provide positioning assistance for the bonding of the touch screen.

For the connection and installation with the driving cylinder 6, as shown in the appendix Figure 3 , a connecting plate seat 8 is fixedly installed at the bottom end of the lifting guide column 7. The push rod end of the driving cylinder 6 is fixedly connected to the middle part of the bottom side of the connecting plate seat 8. The positioning plate seat 2 is movably lifted and installed on the upper part of the fixed support 1 under the drive of the driving cylinder 6.

[0027] As shown in the appendix Figure 2 , the longitudinal positioning flap 3 and the transverse positioning flap 4 are both provided in pairs.

For the fitting and positioning of the workpiece body, positioning notches adapted to the side of the workpiece body are provided on the inner sides of the longitudinal positioning flap 3 and the transverse positioning flap 4. The notch formed by the longitudinal positioning flap 3 and the transverse positioning flap 4 is fitted with the side of the workpiece body for positioning, and the positioning is accurate and fast.

[0028] For the convenience of the flipping actions of the longitudinal positioning flap 3 and the transverse positioning flap 4, as shown in the appendix Figure 1 , the lower corners of the outer sides of the longitudinal positioning flap 3 and the transverse positioning flap 4 are all provided with round chamfers. For the guiding and supporting of the flipping of the longitudinal positioning flap 3 and the transverse positioning flap 4, as shown in the appendix Figure 5 , a flipping guiding surface 10 is provided on the inner side of the plate seat installation groove. When flipping and opening, the outer sides of the longitudinal positioning flap 3 and the transverse positioning flap 4 are in contact with the flipping guiding surface 10. Through the up and down movement of the positioning plate seat 2, the flap structure can perform synchronous up and down flipping movements. When the positioning plate seat 2 moves down, the flap turns up to perform the alignment and fitting positioning of the workpiece body. When the positioning plate seat 2 moves up, the flap turns down to release the positioning of the workpiece body. The whole process can automatically realize the automatic alignment positioning and unloading release operations of the workpiece body, which is beneficial to the loading and unloading installation operations of the jig and greatly improves the operation convenience of the jig.

The vacuum suction cup 5 and the lifting guide column 7 are installed in a concentric distribution. In order to facilitate the communication and driving of the vacuum suction cup 5, an air guide hole is penetrated in the middle of the lifting guide column 7. The upper part of the air guide hole is connected and installed with the vacuum suction cup 5, and the lower part of the air guide hole is connected and installed with an air pipe interface 11. The air pipe interface 11 is connected and installed with the driving end of the external pneumatic driving device through the air pipe. After positioning is completed, the vacuum suction cup 5 arranged on the upper part of the positioning plate seat 2 is used to complete the installation and limitation of the workpiece body through vacuum adsorption. No additional clamping and fixing structure is required. The structure is simple and the operation is reliable. Compared with the traditional side clamping positioning fixture, it has a more stable installation and fixing effect on the workpiece body with rounded corners, and can effectively improve the positioning accuracy of the touch screen bonding operation.

[0030] Working principle or structural principle, when working, the longitudinal positioning flap 3 and the transverse positioning flap 4 are in a flipped-down open state, the workpiece body is placed on the upper part of the positioning plate seat 2 through the handling equipment, and then the cylinder 6 is driven to drive the positioning plate seat 2 to move downward. When the positioning plate seat 2 moves downward, it is guided and supported by the flipping guide surface 10 on the upper part of the fixed support 1, and the longitudinal positioning flap 3 and the transverse positioning flap 4 are flipped and closed synchronously until they reach the lower stop position, and the lower part of the positioning plate seat 2 is in contact with the bottom side of the groove of the fixed support 1, and at the same time, the upper part of the flipping side of the longitudinal positioning flap 3 and the transverse positioning flap 4 is in contact with the side of the positioning plate seat 2 to limit the position. The workpiece body is pushed and moved to the center of the positioning plate seat 2 with the cooperation of the plate 4, and the installation and positioning of the workpiece body are completed by the engagement of the side grooves of the longitudinal positioning flap 3 and the transverse positioning flap 4.
