Description

Technical Field

[0001] The invention belongs to the technical field of vacuum coating, and in particular relates to an outer film rapid cooling device for vacuum coating. Background Art

[0002] Vacuum coating refers to a method of heating metal or non-metallic materials under high vacuum conditions to cause them to evaporate and condense on the surface of the coated part to form a thin film. For example, vacuum aluminum coating, vacuum chromium coating, etc. The vacuum coating process involves multiple different processes, each of which requires a different temperature. The product needs to be cooled after high temperature. Temperature changes directly affect the quality of the coated product. Coating is carried out in a highly sealed vacuum environment.

[0003] At present, the basic cooling method is natural cooling. The cooling speed of this method is generally slow, and it uses single-chip or single-piece cooling. The cooling effect cannot keep up with the coating efficiency of the vacuum film machine, and there may be problems such as untimely cooling and poor cooling effect. Summary of the Invention

[0004] The purpose of the present invention is to provide a device for rapid cooling of outer films for vacuum coating, which realizes automatic clamping and blanking of workpieces through the mutual cooperation of fixed clamping claws, movable clamping claws, guide grooves, and support components, and improves cooling efficiency and cooling effect through cooling components.

[0005] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows:

[0006] A device for rapidly cooling outer films for vacuum coating, comprising a main conveyor belt, a plurality of fixed clamping claws mounted on the main conveyor belt, movable clamping claws slidably mounted on the fixed clamping claws, a first spring mounted between the movable clamping claws and the fixed clamping claws, a limit platform being provided on one side of the main conveyor belt close to the movable clamping claws, a guide groove being provided on the limit platform, a sliding mechanism being mounted in the guide groove, a support assembly, a cooling assembly and a blanking port being sequentially arranged between the main conveyor belt and the limit platform along the conveying direction of the main conveyor belt;

[0007] When the movable clamping claw moves to the top of the support assembly, it drives the workpiece and the main conveyor belt to move synchronously;

[0008] When the movable clamping claw moves to above the cooling assembly, the first spring contracts, the workpiece is clamped by the movable clamping claw and the fixed clamping claw, and is separated from the supporting assembly;

[0009] When the movable clamping claw moves to above the blanking opening, the first spring stretches and the workpiece falls into the blanking opening.

[0010] In the above solution, the cooling component can use air cooling or water cooling equipment, and the main conveyor belt uses a chain plate conveyor belt.

[0011] It is further defined that the fixed clamping claw includes a first V-shaped plate, the first V-shaped plate is fixedly connected to the main conveyor belt, both ends of the first V-shaped plate are fixedly connected to a first fixed block, the first fixed block is horizontally provided with a first through hole, the movable clamping claw includes a second V-shaped plate, the first fixed block is slidably mounted with a first rod in the first through hole, both ends of the second V-shaped plate are fixedly connected to a second fixed block, the first rod is fixedly connected to the second fixed block, the first spring is sleeved on the first rod and is located between the first and second fixed blocks. This structural design increases the scope of application of the device, as circular workpieces are clamped by the inclined surfaces of the first and second V-shaped plates, and rectangular workpieces are clamped by the flat surfaces of the first and second V-shaped plates.

[0012] The sliding mechanism further defines a third rod, the second V-shaped plate being fixedly connected to the second rod, the third rod being fixedly connected to the free end of the second rod, and the first wheel being rotatably mounted on the third rod within the guide groove. This structural design, through the provision of the first wheel, allows the movable clamping claw to move along the guide groove, thereby reducing friction.

[0013] It is further defined that the support assembly includes a fixed table, the fixed table is arranged between the main conveyor belt and the limit table, a first sliding groove is provided on the fixed table, a movable table is slidably installed in the first sliding groove on the fixed table, a second spring is installed in the first sliding groove between the movable table and the fixed table, a second sliding groove is horizontally provided at the lower end of the movable table, a third sliding groove connected to the second sliding groove is vertically provided at the upper end of the movable table, a lifting block is slidably connected to the movable table in the third sliding groove, a top block is fixedly connected to one side of the second sliding groove on the fixed table, and the contact surface between the top block and the lifting block is an inclined surface. With such a structural design, by providing the top block and the lifting block, when the movable table moves, the top block causes the lifting block to push the workpiece between the movable clamping claw and the fixed clamping claw, thereby realizing automatic clamping.

[0014] The movable clamping claw is further defined as being fixedly connected to a first plate, and the movable platform is fixedly connected to one side of the first plate. With this structural design, when the movable clamping claw moves above the support assembly, the first plate and the L-shaped plate cause the movable clamping claw and the movable platform to move synchronously, thereby achieving continuous feeding.

[0015] Furthermore, the main conveyor frame is fixedly connected to a first limit plate, and the fixed clamping claw is fixedly connected to a second limit plate. This structural design allows the first limit plate to support the second limit plate, thereby preventing the main conveyor from deflecting when the movable clamping claw is tightened.

[0016] It is further defined that a plurality of second wheels are evenly spaced and mounted on the first limiting plate. Such a structural design reduces friction by providing the second wheels.

[0017] Further defined, a secondary conveyor belt is disposed below the second rod, the secondary conveyor belt being coaxially driven with the primary conveyor belt, and a plurality of limit brackets are mounted on the secondary conveyor belt, within which the second rod body is slidably mounted. This structural design, through the provision of the secondary conveyor belt and the limit brackets, prevents the second rod body from deflecting.

[0018] The invention adopting the above technical solution has the following advantages:

[0019] 1. Through the cooperation of fixed clamping claws, movable clamping claws, guide grooves and support components, automatic clamping and blanking of workpieces are realized, and the cooling efficiency and cooling effect are improved through the cooling components.

[0020] 2. When the movable clamping claw moves to the top of the supporting assembly, the movable clamping claw and the movable table are moved synchronously through the first plate and the L-shaped plate to achieve continuous feeding.

[0021] 3. By setting the top block and the lifting block, when the movable table moves, the top block enables the lifting block to push the workpiece between the movable clamping claw and the fixed clamping claw to achieve automatic clamping. BRIEF DESCRIPTION OF THE DRAWINGS

Implementations not shown or described in the drawings are forms known to those of ordinary skill in the art. In addition, directional terms mentioned in the embodiments, such as "upper," "lower," "top," "bottom," "left," "right," "front," and "back," are merely references to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0036] like Figures 1 to 4 As shown, a device for rapidly cooling outer films for vacuum coating of the present invention comprises a main conveyor belt 1, on which a plurality of fixed clamping claws 2 are mounted, on which movable clamping claws 3 are slidably mounted, and between which a first spring 31 is mounted, a limit platform 4 is provided on the side of the main conveyor belt 1 close to the movable clamping claw 3, on which a guide groove 41 is formed, and in which a sliding mechanism is mounted, and between the main conveyor belt 1 and the limit platform 4, a support assembly 5, a cooling assembly 6 and a blanking port 7 are sequentially arranged along the transmission direction of the main conveyor belt 1;

[0037] When the movable clamping claw 3 moves to the top of the supporting assembly 5, it drives the workpiece and the main conveyor belt 1 to move synchronously;

[0038] When the movable clamping claw 3 moves to above the cooling assembly 6, the first spring 31 contracts, and the workpiece is clamped by the movable clamping claw 3 and the fixed clamping claw 2 and is separated from the supporting assembly 5;

[0039] When the movable clamping claw 3 moves to above the blanking opening 7 , the first spring 31 stretches and the workpiece falls to the blanking opening 7 .

[0040] The cooling assembly 6 adopts air cooling equipment, and the main conveyor belt 1 adopts a chain plate conveyor belt.

[0041] See Figure 2 and Figure 3The fixed clamping claw 2 includes a first V-shaped plate 21, which is fixedly connected to the main conveyor belt 1. Both ends of the first V-shaped plate 21 are fixedly connected to a first fixed block 22, and a first through-hole is transversely opened on the first fixed block 22. The movable clamping claw 3 includes a second V-shaped plate 32, and a first rod 23 is slidably mounted in the first through-hole of the first fixed block 22. Both ends of the second V-shaped plate 32 are fixedly connected to a second fixed block 33, and the first rod 23 is fixedly connected to the second fixed block 33. The first spring 31 is sleeved on the first rod 23 and is located between the first fixed block 22 and the second fixed block 33. The circular workpiece is clamped by the inclined surfaces of the first V-shaped plate 21 and the second V-shaped plate 32, and the rectangular workpiece is clamped by the flat surfaces of the first V-shaped plate 21 and the second V-shaped plate 32, thereby increasing the applicability of the device.

[0042] The sliding mechanism includes a third rod 34, a second rod 35 fixedly connected to the second V-shaped plate 32, and a free end of the third rod 34 fixedly connected to the second rod 35. The third rod 34 is rotatably mounted with a first wheel 36 within a guide groove 41. The provision of the first wheel 36 allows the movable clamping claw 3 to move along the guide groove 41, reducing friction.

[0043] See Figure 3 and Figure 4 The support assembly 5 includes a fixed platform 51, which is arranged between the main conveyor belt 1 and the limit platform 4. A first sliding groove 52 is provided on the fixed platform 51, and a movable platform 53 is slidably installed in the first sliding groove 52 of the fixed platform 51. A second spring 54 is installed in the first sliding groove 52 between the movable platform 53 and the fixed platform 51. A second sliding groove is horizontally provided at the lower end of the movable platform 53, and a third sliding groove is vertically provided at the upper end of the movable platform 53, which is connected to the second sliding groove. A lifting block 55 is slidably connected to the movable platform 53 in the third sliding groove. A top block 56 is fixedly connected to one side of the second sliding groove of the fixed platform 51, and the contact surface between the top block 56 and the lifting block 55 is an inclined surface. By providing the top block 56 and the lifting block 55, when the movable platform 53 moves, the top block 56 causes the lifting block 55 to push the workpiece between the movable clamping claw 3 and the fixed clamping claw 2, thereby realizing automatic clamping.

[0044] The movable clamping jaw 3 is fixedly connected to a first plate 37, and the movable platform 53 is fixedly connected to one side of the first plate 37. When the movable clamping jaw 3 moves above the support assembly 5, the first plate 37 and the L-shaped plate 57 cause the movable clamping jaw 3 and the movable platform 53 to move synchronously, achieving continuous feeding.

[0045] See Figure 2The first limiting plate 11 is fixedly connected to the frame of the main transmission belt 1, and the second limiting plate 24 is fixedly connected to the fixed clamping claw 2. The first limiting plate 11 supports the second limiting plate 24 to prevent the main transmission belt 1 from deflecting when the movable clamping claw 3 is tightened.

[0046] A plurality of second wheels 12 are evenly spaced and mounted on the first limiting plate 11. The second wheels 12 are provided to reduce friction.

[0047] A secondary transmission belt is provided below the second rod 35. The secondary transmission belt is coaxial with the main transmission belt 1. A plurality of limit racks are installed on the secondary transmission belt. The second rod 35 is slidably installed in the limit racks. The secondary transmission belt and the limit racks prevent the second rod 35 from deflecting.

[0048] The usage and principle of this embodiment are as follows:

[0049] The workpieces are placed one by one on the movable table 53 manually or by machine, and the main conveyor belt 1 and the auxiliary conveyor belt are transported synchronously, so that the fixed clamping claw 2 and the movable clamping claw 3 are transported synchronously.

[0050] When the fixed clamping jaw 2 and the movable clamping jaw 3 move to the top of the movable platform 53, the first plate 37 contacts the L-shaped plate 57, the movable clamping jaw 3 drives the movable platform 53 to move along the first sliding groove 52, and the lifting block 56 lifts the lifting block 55, so that the workpiece is pushed between the fixed clamping jaw 2 and the movable clamping jaw 3;

[0051] When the movable clamping claw 3 moves along the guide groove 41 and the inner width of the guide groove 41 is reduced, the movable clamping claw 3 clamps the workpiece to fix it. At this time, the first plate 37 is separated from the L-shaped plate 57. Due to the elasticity of the second spring 54, the movable platform 53 returns to its original position and waits for the next workpiece to be placed.

[0052] The clamped workpiece is sent to the top of the cooling assembly 6 for air cooling;

[0053] The air-cooled workpiece is sent to the top of the collecting port, the width of the inner portion of the guide groove 41 increases, and due to the elasticity of the first spring 31 , the workpiece falls to the collecting port.

[0054] The above describes in detail the device for rapid cooling of outer films for vacuum coating provided by the present invention. The description of the specific embodiments is intended only to facilitate understanding of the method and core concepts of the present invention. It should be noted that those skilled in the art will be able to make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the claims.
