Description

Technical Field

[0001] The utility model relates to the technical field of glass substrate positioning, in particular to a film covering and positioning mechanism for a chip glass substrate. Background Technique

[0002] The glass substrate is a basic material for the production of flat panel displays. When producing flat panel displays, it is necessary to first cut the glass substrate, cut a whole glass substrate into small glass substrates of different sizes, remove the burrs of the glass substrate, and then cover the film on the glass substrate. However, before covering the film, it is necessary to position the glass substrate. If the positioning is inaccurate, it will cause the film to be misaligned, resulting in the scrapping of the glass substrate. The existing glass substrate positioning mainly adopts the extrusion positioning method. Especially when extruding the side of the glass substrate, it is very easy to cause the glass substrate to deform, and in severe cases, the glass substrate will even break.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] In order to deepen the understanding and recognition of the present utility model below, the technical solutions in the embodiments of the present utility model will be clearly and completely described and introduced with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments, and no formal restrictions are imposed on this embodiment. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] Please refer to Figures 1 - 3, the present utility model provides a technical solution: a film covering and positioning mechanism for a chip glass substrate, including a support plate 1. A guide frame 5 is provided at the lower end of the support plate 1. The guide frame 5 is of an L-shaped structure. The upper end of the guide frame 5 is rotatably connected to the corner of the support plate 1. A positioning table 2 is fixedly connected to the upper end of the support plate 1. Ventilation channels 3 are provided in the middle of both sides of the positioning table 2. A plurality of adsorption ports 4 are provided on both side walls of the positioning table 2. The adsorption ports 4 communicate with the ventilation channels 3. An installation groove 16 is provided at the side end of the positioning table 2. A clamping block 12 is slidably connected in the installation groove 16. A pressure sensor 15 is fixedly connected to the bottom of the installation groove 16. An elastic member 14 is provided between the clamping block 12 and the pressure sensor 15. A guide groove 6 is provided at the upper end of the guide frame 5. A sliding block 7 is slidably connected in the guide groove 6. An electric push rod 11 is fixedly connected between the sliding block 7 and the inner wall of the guide groove 6. The electric push rod 11 is electrically connected to the pressure sensor 15. A plurality of installation holes 9 are provided at the upper end of the guide frame 5. A blocking plate 10 is provided at the upper end of the guide frame 5.

[0017] The positioning table 2 is of an L-shaped structure. The lengths of both sides of the positioning table 2 are the same. The installation groove 16 is located at the corner of the positioning table 2. A clamping groove 13 is provided at the upper end of the clamping block 12. The clamping groove 13 is of a V-shaped structure. The bottom of the clamping groove 13 is at 90 degrees. A driving plate 8 is hinged to the upper end of the sliding block 7. The driving plate 8 is inclined. The top end of the driving plate 8 is hinged to the lower end of the support plate 1. The middle of the blocking plate 10 is of a horizontal structure. The two sides of the blocking plate 10 are of inclined structures. Protrusions are provided at the lower ends of both sides of the blocking plate 10. The protrusions are inserted into the installation holes 9. A pressure sensing module is provided in the middle part of the blocking plate 10. The electric push rod 11 is connected to the pressure sensing module. The support plate 1 is usually in a horizontal state. After placing the glass substrate on the support plate 1, it deforms from the horizontal state to an inclined state to position the glass substrate. After positioning, it returns to the horizontal state again. After placing the glass substrate on the support plate 1, the electric push rod 11 drives the sliding block 7 to move in the guide groove 6. The sliding block 7 can drive the support plate 1 to rotate through the driving plate 8, so that the support plate 1 and the glass substrate are inclined. Under the action of gravity, the glass substrate can slide to the positioning table 2 and is guided and positioned by the positioning table 2. When the corner of the glass substrate is clamped into the clamping groove 12 of the clamping block 12, the clamping block 12 is squeezed and moved by gravity, so that pressure is read on the pressure sensor 15. At this time, negative pressure is generated in the adsorption port 4, so as to adsorb and fix the side end of the glass substrate. The pressure sensor 15 transmits a signal to the electric push rod 11 to reset the support plate 1, which is convenient for subsequent film covering operations. When the sliding block 7 moves, it will hit the pressure sensing module on the blocking plate 10, so as to control the electric push rod to continue working. Place the blocking plate 10 at different positions to control the rotation angle of the support plate 1, so that the support plate 1 can ensure that the glass substrate slides down after rotation, and at the same time avoid the glass substrate from falling due to too large an inclination angle of the support plate 1.

For those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model, and the scope of the present utility model is defined by the appended claims and their equivalents.
