Description

Technical Field

[0001] The present invention relates to the technical field of sputtering coating, and in particular to a coating bracket conveying system. Background Art

[0002] In the sputtering coating process, the target material is positioned in the center of a vacuum chamber, while the workpiece to be coated is placed on a cylindrical support within the chamber. As the target material sputters toward the workpiece surface, the cylindrical support rotates at high speed to evenly coat the workpiece. With the rapid development of the vacuum coating industry, customers are demanding increasingly high coating efficiency. Traditionally, the transport and delivery of the coating support utilizes a reciprocating in-and-out mechanism (open at one end). This requires frequent pumping and deflation in and out of the vacuum chamber, which wastes considerable time. Therefore, a new mechanism is needed to replace the traditional, inefficient transport system. Summary of the Invention

[0003] In view of the above problems, the purpose of the present invention is to provide an efficient coated stent delivery system to improve production efficiency.

[0004] In order to achieve the above object, the technical solution adopted in the present invention is: A coating bracket conveying system includes: a vacuum chamber, a gripping assembly, a suspension bracket, a conveyor and a transfer mechanism; the vacuum chamber is open at both ends, one end is an inlet and the other end is an outlet, the suspension bracket is arranged between the gripping assembly and the vacuum chamber, and the conveyor and the suspension bracket are arranged in a straight line; the transfer mechanism includes an adapted transfer vehicle A and ground rail A, a transfer vehicle B and ground rail B, the ground rail A is arranged at one end of the inlet of the vacuum chamber, and the ground rail B is arranged at one end of the outlet of the vacuum chamber.

[0005] Furthermore, there are two suspension brackets, which are arranged on both sides of the conveyor respectively, and a rotating mechanism is provided on the top of the suspension bracket.

[0006] The grabbing assembly includes a manipulator, a fixture and a jig plate for placing the coated workpiece; the fixture includes a card plate, which has a fixed card slot and a sliding card slot at both ends, and a clamping cylinder is provided at the bottom of the sliding card slot; the card plate is connected to the manipulator.

[0007] The clamping plate is a U-shaped metal plate, and two limit cylinders are symmetrically provided in the longitudinal direction of the clamping plate; the fixture plate is rectangular, and through holes for hanging are provided at both the upper and lower ends.

[0008] Compared with existing technologies, the present invention offers the following advantages: the vacuum chamber is designed with openings at both ends, with one end serving as the inlet and the other as the outlet. An assembly line-like conveying mechanism is employed outdoors, with a mobile transfer vehicle designed at the inlet to transport the coating racks into the chamber. A mobile transfer vehicle is also designed at the outlet to retrieve the coating racks upon exiting the chamber, where they are then connected to the outdoor assembly line, forming a closed transmission chain. This process significantly improves the efficiency and quality of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0010] The technical solution of the present invention is described clearly and completely below with reference to the accompanying drawings and specific embodiments. Example 1:

[0011] Please see Figure 1 This embodiment provides a coating rack conveying system, comprising: a vacuum chamber 10, a gripping assembly 20, a suspension rack 30, a conveyor 40, and a transfer mechanism. The vacuum chamber is open at both ends: one end is an inlet 11, and the other is an outlet 12. Both inlet and outlet are equipped with sealed doors 13. The suspension rack 30 is arranged between the gripping assembly 20 and the vacuum chamber 10. The conveyor 40 and the suspension rack are arranged in a straight line, forming an assembly line pattern to improve conveying efficiency. The transfer mechanism includes a transfer vehicle A 51 and a ground rail A 52, and a transfer vehicle B 53 and a ground rail B 54. Ground rail A is arranged at the inlet end of the vacuum chamber, and ground rail B is arranged at the outlet end of the vacuum chamber. When a coating rack enters the chamber, the transfer vehicle A moves on the ground rail A to deliver it. When a coating rack exits the chamber, the transfer vehicle B picks it up and then connects to the outdoor assembly line, forming a closed transmission chain.

[0012] See Figure 4-6The gripping assembly includes a manipulator 21, a fixture 22, and a jig plate 23 for placing the coated workpiece. The fixture includes a clamping plate 220, with a fixed slot 221 and a sliding slot 222 at each end of the clamping plate, and a clamping cylinder 223 at the bottom of the sliding slot; the clamping plate is connected to the manipulator.

[0013] See Figure 5 The card plate is a U-shaped metal plate, and two limiting cylinders 224 are symmetrically provided in the longitudinal direction of the card plate. Figure 6 The fixture plate is rectangular, and has through holes 230 for hanging at both ends. Example 2:

[0014] On the basis of Example 1, in order to further improve the conveying efficiency, there are two hanging brackets 30, which are arranged on both sides of the conveyor 40, and a rotating mechanism 31 is provided on the top of the hanging bracket. The rotating mechanism can drive the coating bracket to rotate, making it more convenient to hang and take the fixture plate. Figure 2-3 As shown, the rotating mechanism 31 uses a motor with a tapered output shaft. A turntable 32 is mounted on the suspension bracket, which can be raised to allow the motor's output shaft to be inserted into the circular hole at the top center of the coating bracket. Once tightened, the motor's output shaft drives the coating bracket to rotate under the action of friction.

[0015] Due to the large size of the coating bracket, the conveyor adopts a roller conveyor. At the same time, the transfer vehicle and the suspension bracket are also equipped with roller structures and driven by motors to ensure good support and smooth movement. For safety reasons, an arc-shaped guardrail 55 is installed on the transfer vehicle.

[0016] In the preferred solution, a six-axis manipulator is used. When the jig plate with the coated workpiece installed is hung, the jig plate is first transported to a fixed workstation 60 with relative accuracy. Then the manipulator moves accurately to the position of the jig plate to be grasped, the clamping cylinder is actuated, and the upper and lower slots of the fixture clamp the upper and lower end faces of the jig plate. Then the two positioning cylinders are limited to ensure that the relative position of the jig plate does not shift during the movement, ensuring the accuracy and reliability of the position when the plate is hung. The jig plate is hung on the coating bracket using the through holes on the jig plate. After one side is fully hung, the coating bracket rotates to reveal an empty space. Similarly, after the coating is completed, the manipulator cooperates with the fixture to complete the removal. The removed jig plate is placed on the workstation 61, and the empty coating bracket is sent to the upper hanging with the conveyor, forming a closed transmission chain.
