Description

Technical Field

[0001] The utility model relates to a turnover device, in particular to a turnover device for coating film. Background Art

[0002] When coating film, it is necessary to place the coating substrate in the coating chamber. Generally, the coating is carried out on one side only. When coating the other side, the coating substrate needs to be taken out of the coating chamber, manually turned over and then put back. Or a turnover device can be set in the coating chamber. However, the clamping force of the existing turnover device on the coating substrate is constant. If the clamping force is too small, the coating substrate may fall off during the turnover process. If the clamping force is too large, the surface of the coating substrate may be scratched. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a turnover device for coating film, which solves the technical problem that it is difficult to control the clamping force of the existing turnover device on the coating substrate.

[0004] To achieve the above purpose, the utility model provides a turnover device for coating film, which includes a power structure, a coating chamber, a first clamping structure and a second clamping structure;

[0005] The power structure is fixedly arranged outside the coating chamber;

[0006] The first clamping structure includes a connecting rod, a fixed frame, a top plate, a lead screw, a lower pressing plate, a pin rod and a spring. One end of the connecting rod is in transmission connection with the power structure. The rod body of the connecting rod is rotatably connected with the coating chamber. The other end of the connecting rod is fixedly connected with the fixed frame. The fixed frame is threadedly connected with the lead screw. One end of the lead screw is rotatably connected with the top plate. The top plate is suspended in the fixed frame. One side of the fixed frame abuts against the top plate. A lower pressing plate is arranged below the top plate. A pin rod is fixedly connected to the top of the lower pressing plate. The pin rod sequentially passes through the top plate and the fixed frame. The pin rod is sleeved with a spring. The two ends of the spring respectively abut against the top plate and the lower pressing plate;

[0007] The structure of the second clamping structure is the same as that of the first clamping structure. The second clamping structure and the first clamping structure are arranged in mirror symmetry in the coating chamber;

[0008] The power structure is used to drive one connecting rod to rotate.

[0009] Preferably, the power structure includes a motor, a first sprocket, a chain and a second sprocket;

[0010] The motor is fixedly connected to the outer side wall of the coating chamber. The output end of the motor is key-connected to the first sprocket. The first sprocket is meshed with the chain. The chain is also meshed with the second sprocket. The second sprocket is key-connected to the connecting rod.

[0011] Preferably, the connecting rod of the second clamping structure is rotatably connected to the side wall of the coating chamber.

[0012] Preferably, a pull ring is fixedly provided at the top of the pin rod, and a through hole for the pin rod to pass through is provided at the top of the fixed frame, and the pull ring cannot pass through the through hole.

[0013] The beneficial effects achieved by the present utility model are as follows:

[0014] In the present utility model, the lower pressing plate presses and fixes the coating substrate at the bottom of the fixed frame. The force of the lower pressing plate on the coating substrate is provided by the restoring force of the spring. When the pressure of the lower pressing plate on the coating substrate is insufficient, the screw rod can be rotated to move the top plate downward, so that the spring is further compressed, thereby adjusting the pressure between the lower pressing plate and the coating substrate, ensuring that the coating substrate is firmly fixed, and at the same time preventing the pressure between the lower pressing plate and the coating substrate from being too large and damaging the surface of the coating substrate.

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model. Many specific details are set forth in the following description in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0021] As Figure 1 、 Figure 2As shown in the figure, the utility model discloses a flipping device for coating, which comprises a power structure 1, a coating chamber 2, a first clamping structure 3 and a second clamping structure 4. The power structure 1 is used to drive the first clamping structure 3 to rotate. For example, Figure 2 As shown in the figure, the power structure 1 comprises a motor 11, a first sprocket 12, a chain 13 and a second sprocket 14. The motor 11 is fixedly connected to the outer side wall of the coating chamber 2. The output end of the motor 11 is key-connected to the first sprocket 12. The first sprocket 12 meshes with the chain 13. The chain 13 also meshes with the second sprocket 14. The second sprocket 14 is located in the middle of the side wall of the coating chamber 2. The second sprocket 14 is drivingly connected to the first clamping structure 3. In the use state, the second sprocket 14 and the first sprocket 12 tighten the chain 13.

[0022] For example, Figure 1 and Figure 3 As shown in the figure, the first clamping structure 3 comprises a connecting rod 31, a fixed frame 32, a top plate 33, a lead screw 34, a lower pressing plate 35, a pin rod 36 and a spring 37. Taking Figure 1 as an example, the left end of the connecting rod 31 is key-connected to the second sprocket 14. The rod body of the connecting rod 31 passes through the side wall of the coating chamber 2 and is rotatably connected to the side wall. The right end of the connecting rod 31 extends into the coating chamber 2. The right end of the connecting rod 31 is fixedly connected to the fixed frame 32. A through groove is formed in the middle of the fixed frame 32. A lead screw 34 is threadedly connected to the top of the fixed frame 32. The bottom end of the lead screw 34 is rotatably connected to the top plate 33. The top plate 33 is arranged in the through groove. A lower pressing plate 35 is arranged below the top plate 33. Two pin rods 36 are fixedly connected to the top of the lower pressing plate 35. These two pin rods 36 are symmetrically arranged. The pin rods 36 sequentially pass through the top plate 33 and the fixed frame 32 and extend above the fixed frame 32. A spring 37 is sleeved on the pin rod 36. The two ends of the spring 37 are respectively abutted against the top plate 33 and the lower pressing plate 35.

[0023] In order to be able to lift the pin rod 36 more conveniently, as Figure 3 shown in the figure, a pull ring 361 is fixedly arranged at the top of the pin rod 36. The top wall of the fixed frame 32 has a through hole for the pin rod 36 to pass through. The pull ring 361 cannot pass through the through hole.

[0024] Referring to Figure 1 again, the structure of the second clamping structure 4 is the same as that of the first clamping structure 3. The two are arranged in mirror symmetry in the coating chamber 2. The connecting rod 31 of the second clamping structure 4 is rotatably connected to the side wall of the coating chamber 2.

[0025] In use, one end of the coated substrate is clamped in the first clamping structure 3. The specific operation method is as follows: First, pinch the pull ring 361 and lift the pin rod 36 upward to raise the height of the lower pressing plate 35. Place the coated substrate under the lower pressing plate 35 and then release the pull ring 361. At this time, the coated substrate is clamped by the lower pressing plate 35 and the fixed frame 32. Subsequently, the operator can feel whether the clamping force is appropriate according to experience. If the clamping force is too large or too small, the screw rod 34 can be rotated. The screw rod 34 drives the top plate 33 to move upward or downward. During this process, the spring 37 is always in a compressed state, that is, the lower pressing plate 35 always abuts against the coated substrate. When the top plate 33 moves upward, the length of the spring 37 becomes longer and the pressure between the lower pressing plate 35 and the coated substrate becomes smaller. When the top plate 33 moves downward, the spring 37 is further compressed and the pressure between the lower pressing plate 35 and the coated substrate becomes larger. Then, the other end of the coated substrate is clamped in the second clamping structure 4 in the same way.

[0026] When flipping is required, start the motor 11. The motor 11 drives the first sprocket 12 to rotate, which in turn drives the chain 13 to rotate. The chain 13 drives the second sprocket 14 to rotate, and the second sprocket 14 drives the connecting rod 31 to rotate, so that the coated substrate rotates. The coated substrate then drives the second clamping structure 4 to rotate, thus completing the flipping of the coated substrate.

[0027] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.
