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.

[0030] Example 1

[0032] The mating components include a supporting plate 19, a through-opening 20, a receiving plate 21, a sleeve 22, a guide rail 23, a clamp head 24 and a mating clamp head 25. The two output ends of the double-axis telescopic cylinder 15 are fixed with supporting plates 19, and one end of the driving device shell 5 is provided with a through-opening 20. A receiving plate 21 is fixed to one end of the supporting plate 19, and a sleeve 22 is fixed to the top of the receiving plate 21. A guide rail 23 is slidably connected to the top of the two sleeves 22, and the guide rail 23 is fixed to the inner side of the driving device shell 5. A clamp head 24 is fixed to one end of the receiving plate 21, and the clamp head 24 is gap-matched with the through-opening 20. A mating clamp head 25 corresponding to the position of the clamp head 24 is fixed to one end of the strip shell 4 close to the driving device shell 5. A notch is provided on the inner side of the clamp head 24, and the notch matches the size of the mating clamp head 25, so as to facilitate the clamping and fixing effect of the clamp head 24 on the mating clamp head 25.

[0033] The pulling mechanism also includes lateral anti-drift wheels 16 and bottom support wheels 17. Both sides of the strip shell 4 are evenly rotatably connected with multiple lateral anti-drift wheels 16 and bottom support wheels 17. The lateral anti-drift wheels 16 and bottom support wheels 17 are in close contact with the inner side of the sliding groove. Through the guiding effect of the lateral anti-drift wheels 16 and the bottom support wheels 17, the user can quickly pull out the strip shell 4 when pulling it.

[0034] The grinding disc 3 is composed of a magnetic stainless steel layer 11, a sponge layer 12 and an alumina grinding layer 13. The use of high-precision alumina material ensures uniform grinding and durability. At the same time, each grinding disc 3 is connected to the machine 1 through an elastic connection mechanism, so that it can adapt to the slight deformation and unevenness of the surface of the glass substrate.

[0035] A water injection joint 14 is provided on the inner side of the strip shell 4 and at a position vertically corresponding to the grinding disc 3 . When grinding, the water source is connected through the water injection joint 14 , which can improve the grinding effect of the grinding disc 3 on the OLED product panel 8 .

[0036] Example 2

[0037] Embodiment 1 is further optimized, specifically, as Figure 2 , Figure 5 , Fig. 9 and Fig.10 As shown, a loading platform is provided on one side of the machine 1, and an OLED product panel 8 is placed on the top of the loading platform. A plurality of groups of pressing rubber rollers 9 are provided on the inner side of the machine 1, and one end of the pressing rubber rollers 9 are fixed to the output end of the motor, and the motor is fixed to the machine 1. The outer sides of the pressing rubber rollers 9 are in contact with the OLED product panel 8. A driving grinding mechanism is installed between the grinding disc 3 and the strip shell 4. The driving grinding mechanism is used to drive the grinding disc 3 to grind the OLED product panel 8. When the grinding disc 3 grinds the OLED product panel 8, the grinding disc 3 located at the top rotates clockwise, and the grinding disc 3 located at the bottom rotates counterclockwise. The lateral force generated during grinding can be offset by the positioning of the pressing rubber rollers 9.

[0038] The driving grinding mechanism includes a power gear set 6, a transmission gear set 7 and a grinding rising and lowering cylinder 10. A driving motor is fixed to one end of the driving device shell 5. A power gear set 6 is arranged on the inner side of the driving device shell 5. The output end of the driving motor is fixed to a gear on the power gear set 6. A transmission gear set 7 is arranged on the inner side of the strip shell 4. The transmission gear set 7 is meshed and connected with the power gear set 6. A plurality of grinding rising and lowering cylinders 10 are evenly fixed to the bottom of the transmission gear set 7. The output end of the grinding rising and lowering cylinder 10 is fixed to the grinding disc 3. After the grinding disc 3 is replaced, the handle is pushed to make the strip shell 4 reset and move along the inner side of the sliding groove until the pliers 24 correspond to the position of the matching clamp 25. Then, the double-axis telescopic cylinder 15 is started to shrink the output end of the double-axis telescopic cylinder 15 until the two pliers 24 clamp the matching clamp 25 to achieve the positioning effect.

[0039] From the above, we can know that:

[0040] The present invention is directed to the following technical problem: In the existing OLED manufacturing process, since the grinding disc is a consumable, grinding will slowly wear away the oxide layer of the grinding disc during use, so it needs to be replaced frequently. Traditional replacement requires entering the machine, which has disadvantages such as low efficiency, poor adaptability, and safety issues. Since the existing equipment is large, replacement requires a dedicated bracket, and people have to lie on the bracket to work, which is very inconvenient and unsafe. The technical solutions of the above embodiments are adopted. At the same time, the implementation process of the above technical solution is:

[0041] The device is electrically connected to an external power source. In the initial state, when the grinding disc 3 is working, the strip shell 4 and the drive device shell 5 are both in the sliding groove, and the power gear set 6 is meshed and connected with the transmission gear set 7, so that the grinding ascending and descending cylinder 10 drives the grinding disc 3 to rotate, and the grinding disc 3 located at the top and the grinding disc 3 located at the bottom are controlled to rotate in opposite directions, so that the grinding disc 3 grinds the OLED product panel 8;

[0042] When the grinding disc 3 needs to be replaced later, first start the double-axis telescopic cylinder 15. The output end of the double-axis telescopic cylinder 15 pushes the supporting plate 19 to move, so that the supporting plate 19 drives the receiving plate 21 to move synchronously, and then the two sliding sleeves 22 move along the outer side of the guide rail 23 until the two clamp heads 24 are separated from the matching clamp heads 25. At this time, the strip shell 4 and the drive device shell 5 are no longer connected. Then pull the handle, and under the auxiliary guidance of the lateral anti-deviance wheel 16 and the bottom support wheel 17, the strip shell 4 can move along the inner side of the sliding groove, so that the strip shell 4 is pulled out, and then the grinding disc 3 on the strip shell 4 can be replaced.

[0043] Through the above configuration, the present application can certainly solve the above technical problems and achieve the following technical effects:

[0044] 1. The present invention greatly improves the efficiency, accuracy and safety of the operation through the structural design of the pull-out mechanism and the matching components. Specifically, its high efficiency is reflected in the adoption of a convenient pull-out design, which allows the operator to easily complete the pull-out operation of the grinding disc 3 by standing beside the machine 1 without having to climb onto the machine 1, which is convenient for the subsequent replacement of the grinding disc 3, thereby greatly reducing the operation time and improving the work efficiency, which greatly reduces the safety hazards in the operation process and completely changes the habit of operators in traditional operations who need to climb the machine for maintenance or replacement of parts.

[0045] 2. In terms of accuracy, after the grinding disc 3 is replaced, the present invention utilizes a pull-out mechanism and matching components to ensure that the replaced parts are accurately pushed back to the preset position. This process is both rapid and stable. At the same time, the upper and lower grinding discs 3 can be controlled to achieve reverse rotation for grinding, thereby achieving high grinding efficiency.

[0046] In terms of accuracy, after the grinding disc 3 and the strip shell 4 are replaced, the present invention utilizes a precise pull-out clamping device to ensure that the replaced parts are accurately pushed back to the preset positions. This process is both rapid and stable, effectively avoiding position deviations that may be caused by manual operation and ensuring the high-precision requirements of the grinding operation.
