Description

Technical Field

[0001] The present invention belongs to the technical field of substrate coating, and in particular relates to a surface coating device and a coating method for an LED aluminum substrate. Background Art

[0002] Traditional coating devices usually use processes such as evaporation coating or magnetron sputtering coating to form a functional layer on the surface of the substrate. The functional layer needs to have good adhesion with the base film so that the functional layer is not easily peeled off from the base film. However, in the existing technology, in order to make the coating layer have good adhesion, the substrate is usually placed in a process chamber and preheated. The need for preheating in advance prolongs the coating process time, resulting in low substrate coating efficiency. Summary of the Invention

Under the action of the first electric push rod 34, the moving part 35 is driven to move back and forth on the base 31, driving the substrate in the traction channel 33, so that the substrate is heated under the action of the heating tube, the coating time is shortened, and the adhesion between the coating layer and the substrate is improved. The moving part 35 includes a moving platform 351, at least two groups of clamping parts, a second electric push rod 352 and a transmission rod 353 with the same number as the clamping parts.

[0059] In a further embodiment, the clamping portion includes an L-shaped movable table 354, a clamping plate 355 and a plurality of through holes 356. The L-shaped movable table 354 is slidably mounted on the movable table 351. The direction of movement of the L-shaped movable table 354 is perpendicular to the direction of movement of the movable table 351. The clamping plate 355 is mounted on the top of the L-shaped movable table 354. The clamping plate 355 is located above the placement table 32. The through holes 356 are arranged on the clamping plate 355. The clamping plates 355 approach or move away from each other under the action of the second electric push rod 352. When the clamping plates 355 approach each other, the through holes 356 approach each other to form a closed space for clamping the substrate.

[0060] In a further embodiment, the conveying assembly 4 includes a mounting frame 41, a first servo motor 42, at least two crawlers 43, several placement plates 44, a detection hole 45 and a detection probe. In this embodiment, two crawlers 43 are used.

The detection probe is connected to the first servo motor 42 through an external controller, and detects whether the detection hole 45 is blocked by the detection probe to detect whether there is a substrate on the placement plate 44, ensuring that there is a substrate on the transferred placement plate 44, effectively avoiding the placement plate 44 being coated when there is no substrate on the placement plate 44, avoiding waste of raw materials, and also improving the success rate of coating.

[0061] In a further embodiment, the conveying component 4 also includes at least two groups of proximity switches 46, at least two groups of blocking parts and lifting parts. In this embodiment, two groups of proximity switches 46 and two groups of blocking parts are used. The linear array of the proximity switches 46 is installed on the mounting frame 41, and the linear array of the blocking parts is installed on the mounting frame 41. The blocking parts are electrically connected to the proximity switches 46. The lifting part is installed on the mounting frame 41, and the lifting part is located between the tracks 43. The blocking part cooperates with the proximity switch 46 through the blocking part. When the placement plate 44 approaches the proximity switch 46, the blocking part rises to block the placement plate 44, and uses the detection probe to detect whether there is a substrate on the placement plate 44, and moves the placement plate 44 containing the substrate to the top of the lifting part, and lifts the placement plate 44 containing the substrate through the lifting part. When the placement plate 44 is lifted to a specific height, the substrate on the placement plate 44 is coated. Among them, the blocking part includes a first fixed frame 47, a third electric push rod 48 and an L-shaped baffle 49, the first fixed frame 47 is installed on the mounting frame 41, the third electric push rod 48 is installed between the tracks 43 through the first fixed frame 47, and the L-shaped baffle 49 is installed at the moving end of the third electric push rod 48. The L-shaped baffle 49 moves up and down between the tracks 43 under the drive of the third electric push rod 48.

If it is detected that there is a substrate on the placement plate 44, the external controller controls the third electric push rod 48 to retract, so that the placement plate 44 continues to move toward the lifting part.

[0062] In a further embodiment, the lifting portion includes a U-shaped cover 410, a fourth electric push rod 411, a positioning plate 412 and at least two sets of support plates 413, the U-shaped cover 410 is fixedly mounted on the mounting frame 41, the U-shaped cover 410 is located between the tracks 43, the fourth electric push rod 411 is mounted in the U-shaped cover 410, the positioning plate 412 is mounted on the moving end of the fourth electric push rod 411, and the support plates 413 are mounted at both ends of the positioning plate 412. When the plate 44 is placed When it moves to the top of the lifting part, the proximity switch 46 and the blocking part cooperate with each other to stop the placement plate 44 above the lifting part, and with the cooperation of the fourth electric push rod 411 and the support plate 413, the placement plate 44 and the substrate are pushed upward, waiting for the coating assembly to coat the substrate on the placement plate 44. When the substrate is coated, the fourth electric push rod 411 contracts, causing the placement plate 44 to fall onto the crawler 43. Under the action of the crawler 43, the placement plate 44 and the substrate are transported to the designated position to wait for further processing.

[0063] Through the above technical solution, the present invention can achieve the following working process:

[0064] When the substrate needs to be coated, the substrate to be coated is fed into the conveying track 21 and moved within the conveying track 21 toward the rectangular through hole 22. When the substrate to be coated moves to the rectangular through hole 22, it is driven by the pushing portion 23 to separate from the conveying track 21 and fall into the traction channel 33. After the substrates fall into the traction channel 33 in sequence, the heating tube heats the substrates in the traction channel 33 to increase the temperature of the substrates. At the same time, the first electric push rod 34 drives the moving portion 35 to move back and forth. Driven by the moving portion 35, the substrate moves within the traction channel 33, so that the substrate with the increased temperature moves out of the traction channel 33 and falls into the conveying track 33. In the component 4, a detection probe is used to pass through the detection hole 45 to the placement plate 44 to detect whether the substrate falls on the placement plate 44. When the presence of the substrate is detected on the placement plate 44, the first servo motor 42 drives the crawler 43 to rotate, driving the placement plate 44 away from the heating component 3. When the placement plate 44 moves to the top of the lifting part, the first servo motor 42 stops working and, under the action of the lifting part, moves the placement plate 44 upward for coating. After the coating is completed, the placement plate 44 is placed on the crawler 43 under the action of the lifting part. With the cooperation of the first servo motor 42 and the crawler 43, the placement plate 44 is moved to a predetermined position to wait for further processing.
