It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] Example 1

[0028] Reference Figure 1-4 A steel capsule self-adjusting grinding platform device comprises a machine platform 1 and a machine top frame 2. The machine top frame 2 is fixed on the top of the machine platform 1. A first protective shell 3 and a second protective shell 4 are arranged on the top of the machine platform 1 and located inside the machine top frame 2. The second protective shell 4 is fixed to the machine platform 1. A moving matching mechanism is arranged between the first protective shell 3 and the second protective shell 4. The moving matching mechanism is used to move and carry the glass substrate of the automobile on-board display. A positioning grinding mechanism is arranged on the inner side of the machine top frame 2. The positioning grinding mechanism is used to assist the moving matching mechanism in grinding the glass substrate.

[0029] The mobile matching mechanism includes a driving component and a self-adjusting component. The driving component is installed on the inner side of the second protective shell 4, and the self-adjusting component is installed on the top of the driving component.

[0030] The driving assembly includes a bearing seat 5, a driving motor 6, a transmission wheel 7, a forward screw 8, a screw nut 9, a mounting plate 10, a guide rail slider 11 and a forward guide rail 12. The driving motor 6 is fixed to the top of the machine 1 and located inside the second protective shell 4. A pulley is fixed to the output end of the driving motor 6. The outer side of the pulley is connected to the driving wheel 7 through a belt. The forward screw 8 is fixed to the inner side of the driving wheel 7. The outer side of the forward screw 8 is threadedly connected to the screw nut 9. The top of the machine 1 and the positions corresponding to the first protective shell 3 and the second protective shell 4 are fixed with forward guide rails 12, one of which is located inside the second protective shell 4, and the other forward guide rail 12 is fixed to the first protective shell 3. One side of one of the forward guide rails 12 is fixed There is a bearing seat 5, the inner side of the bearing seat 5 is rotatably connected to the forward screw rod 8 through a bearing, the other end of the forward screw rod 8 is rotatably connected to one of the forward guide rails 12 through a bearing, and a mounting plate 10 is installed on the top of the two forward guide rails 12, the mounting plate 10 is fixed to the sealing box body 13, the mounting plate 10 is fixed to the screw nut 9, and a plurality of guide rail sliders 11 are evenly fixed on the bottom of the mounting plate 10, and the guide rail sliders 11 are all slidably connected to the forward guide rails 12; a plurality of serpentine water spray pipes 26 are evenly fixed on the inner side of the forward guide rail 12, when the drive motor 6 is started, the output end of the drive motor 6 drives the pulley to rotate, and then the mounting plate 10 drives the steel capsule and the glass substrate to move; the steel capsule is a steel plate with small ductility, and there is electrostatic adsorption on the upper surface of the steel capsule.

[0031] The self-adjusting component includes a sealed box 13, a steel bag and an inflation interface 14. The sealed box 13 is fixed on the top of the driving component, the inflation interface 14 is fixed on one side of the sealed box 13, and the steel bag is fixed on the top of the sealed box 13; the steel bag specifically refers to a steel sheet with a certain elastic deformation ability. When the driving component drives the glass substrate to move forward as a whole, through the inflation of the sealed box 13, if the glass substrate is uneven, the steel bag will deform accordingly, so that it can adapt to the glass substrate and the grinding disc 22, so that the grinding is more complete; at the same time, when it is not in a working state, the steel bag is in a non-inflated state.

[0032] Example 2

[0033] Embodiment 1 is further optimized, specifically, as Figure 5As shown, the positioning grinding mechanism includes a mounting frame 15, a lifting motor 16, a movable connecting frame 17, a connecting plate 18, a first guide rail 19, a movable bracket 20, a rotating motor 21, a grinding disc 22 and a lifting screw 25. The mounting frame 15 is fixed to the top of the inner side of the top frame 2, the lifting motor 16 is fixed to the top of the mounting frame 15, the output end of the lifting motor 16 passes through the mounting frame 15 and is fixed with the lifting screw 25, the outer side of the lifting screw 25 is threadedly connected with the movable connecting frame 17, both ends of the movable connecting frame 17 are slidably connected with the first guide rail 19, the first guide rail 19 is fixed to the inner side of the mounting frame 15, and the inner side of the movable connecting frame 17 is fixed with the connecting plate 18. 8. A movable bracket 20 is assembled below the connecting plate 18, a rotating motor 21 is fixed on the top of the movable bracket 20, and a grinding disc 22 is fixed on the output end of the rotating motor 21 through the movable bracket 20. The grinding disc 22 is made of alumina and has wear-resistant properties to ensure uniform grinding and durability; the lifting motor 16 is started, and the output end of the lifting motor 16 drives the lifting screw 25 to rotate, so that the movable connecting frame 17 can be adjusted up and down, so that the grinding disc 22 can be adjusted to a height that contacts the glass substrate. When the glass substrate on the steel capsule contacts the grinding disc 22, the grinding process is realized as the steel capsule drives the glass substrate to move continuously.

[0034] Example 3

[0035] Embodiment 2 is further optimized, specifically, as Figure 5-6 As shown, the positioning grinding mechanism also includes a weight-reducing cylinder 23 and a second guide rail 24. The weight-reducing cylinder 23 is fixed to the top of the movable bracket 20, and the output end of the weight-reducing cylinder 23 is fixed to the connecting plate 18. Both ends of the movable bracket 20 are slidably connected to the second guide rail 24, and the second guide rail 24 is fixed to the inner side of the mounting frame 15. In the actual grinding process, the overall downward pressure on the glass substrate may cause broken pieces. By adjusting the advance amount of the output end of the weight-reducing cylinder 23, the weight can be lifted upward, thereby reducing the force acting on the glass substrate during grinding and preventing the generation of broken glass substrates.

[0036] From the above, we can know that:

[0037] The present invention is directed to the following technical problem: In the existing on-board LCD manufacturing process, residual glue will be generated due to the sealing of the upper process. The traditional grinding and cleaning method usually uses a single aluminum plate as a support grinding platform, but the glass substrate of the on-board display of the car is very long. At this time, the grinding platform is too long to ensure a good platform flatness. In addition, the grinding platform needs to move forward during grinding, and it is even more impossible to ensure that the grinding disc and the grinding platform are not relatively parallel. There are disadvantages such as incomplete residual glue during grinding and residual glue remaining. The technical solutions of the above embodiments are adopted. At the same time, the implementation process of the above technical solution is:

[0038] In the specific implementation process, the electrical and pneumatic components in the present invention use PLC systems and multiple sensors to achieve intelligent control of the cleaning process, making the operation more accurate and convenient;

[0039] The device is moved to a designated area, and then the device is electrically connected to an external power source. When the glass substrate needs to be ground, the sealed box 13 is first inflated through the inflation interface 14, and the steel capsule will swell and deform as the air is inflated. The glass substrate is electrostatically adsorbed on the upper surface of the steel capsule, and then the drive motor 6 and the lifting motor 16 are started. The output end of the drive motor 6 drives the pulley to rotate, so that the pulley drives the transmission wheel 7 to rotate synchronously through the belt. Because the transmission wheel 7 is fixed to the forward screw rod 8, the forward screw rod 8 is threadedly connected to the screw nut 9, the screw nut 9 is fixed to the mounting plate 10, and the guide rail slider 11 at the bottom of the mounting plate 10 is slidably connected to the forward guide rail 12, the mounting plate 10 can drive the steel capsule and the glass substrate on the sealed box 13 to move. When the glass substrate and the grinding disc 22 are in contact for grinding, the downward pressure from the grinding disc 22 causes the steel capsule to deform as it is not parallel. If there is residual glue on the glass substrate, the steel capsule can deform adaptively to ensure flatness.

[0040] When the sealed box is inflated during operation, the steel bag will swell and deform as the air is inflated, but the surface of the steel bag remains flat (such as Figure 7 shown);

[0041] During grinding, the upper surface of the steel capsule electrostatically absorbs the glass to be ground. When the glass and the grinding disc come into contact and grind, due to the different positions of the contaminants on the glass, the downward force of the grinding disc is different, causing the steel capsule to deform due to non-parallelism (such as Figure 8 As shown, the deformation is exaggerated to demonstrate the effect), so as to ensure the parallelism between the grinding disc and the glass.

[0042] Through the above configuration, the present application can certainly solve the above technical problems and achieve the following technical effects:

[0043] The present invention adopts the structural design of the mobile matching mechanism and the positioning grinding mechanism, and inflates the steel bag to produce deformation, so that the grinding disk 22 and the steel bag below the grinding disk 22 can be relatively completely parallel, thereby improving the removal rate of residual glue and foreign matter on the surface of the glass substrate, thereby improving product quality and yield, and accelerating work efficiency to meet high-quality cleaning requirements. In addition, the combination of the PLC system and a variety of sensors is adopted to realize intelligent control of the cleaning process, making the operation more accurate and convenient.
