Description

Technical Field

[0001] The utility model belongs to the technical field of metal part cleaning, and particularly relates to a pre-treatment conveying device for PVD-coated metal parts. Background Technique

[0002] Metal parts can be seen everywhere in our daily life. In order to enhance the wear resistance, high temperature resistance, corrosion resistance, oxidation resistance, radiation protection, conductivity, magnetism conduction, insulation and decoration of metal parts, a common practice is to deposit a protective film on the surface of metal parts through vacuum ion coating technology. However, since there are sundries such as oil stains, residual glue, residual wax or dust on the surface of many parts after production, which is not conducive to depositing the protective film, it is necessary to perform DI water ultrasonic cleaning on the metal parts before vacuum coating. For example, in the Chinese patent with the application number 202122257454.5, a pre-treatment conveying device for PVD-coated metal parts is mentioned. This conveying device hooks the metal part cleaning rack through a hook in an open state and transports the metal part cleaning rack to the processing position of the next process. However, in the above-mentioned conveying device, since the hook is in an open state, it is inevitable that the metal part cleaning rack accidentally falls off the hook during the transportation process of the metal part cleaning rack, and it is impossible to ensure the continuous progress of the transportation work. Content of the Utility Model

[0003] The purpose of the utility model is to provide a pre-treatment conveying device for PVD-coated metal parts, so as to solve the problem that the hook in an open state cannot avoid the accidental detachment of the metal part cleaning rack from the hook during the transportation process of the metal part cleaning rack, and it is impossible to ensure the continuous progress of the transportation work mentioned in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A pre-treatment conveying device for PVD-coated metal parts, including a fixed frame and a movable frame.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-6 As shown, the present utility model provides a technical solution: a pre-treatment transportation device for PVD-coated metal parts, including a fixed frame 1 and a movable frame 2. The movable frame 2 is movably arranged on the fixed frame 1, and a slide rail is provided on the movable frame 2. A slider 3 is slidably connected to the slide rail, and a hook component 4 is provided on the slider 3. The hook component 4 includes a mounting seat 5, a moving column 6, a hook 7, a fixed column 8, a limit block 9, and a first electric push rod 10. The hook 7 is rotatably connected inside the mounting seat 5. The fixed column 8 is fixed at a position on the inner side wall of the mounting seat 5 close to the hook 7. The moving column 6 and the limit block 9 are both fixed at positions on the outer side wall of the mounting seat 5 close to the hook 7. The moving column 6 abuts against the tail end of the hook 7, and the limit block 9 abuts against the bent end of the hook 7. The first electric push rod 10 is arranged at a position behind the hook 7 inside the mounting seat 5, and the output end of the first electric push rod 10 is connected to a moving plate 11;

[0024] The moving column 6, the hook 7, the fixed column 8, and the limit block 9 are on the same plane;

[0025] Two hooks 7 are provided, and a spring is provided between the two hooks 7.

[0026] In the above technical solution, the first electric push rod 10 drives the moving plate 11 to move downward. The movement of the moving plate 11 drives the moving column 6 to move downward. The movement of the moving column 6 pushes the tails of the two hooks 7 closer to each other, so as to open the hook ends of the two hooks 7, thereby hooking the metal part cleaning rack. Then, the first electric push rod 10 drives the moving plate 11 to move upward, thereby driving the moving column 6 to move upward. At the same time, the tails of the two hooks 7 move away from each other under the deformation force of the spring, and then the hook ends of the two hooks 7 are closed, so that the hooked metal part cleaning rack can be restricted at the hook ends of the two hooks 7, which is beneficial to preventing the metal part cleaning rack from accidentally falling off the hook 7 during the movement process.

[0027] In this embodiment, preferably, a guiding groove is provided inside the mounting seat 5, and the guiding groove is located between the moving column 6 and the moving plate 11. The moving column 6 passes through the guiding groove and is connected to the moving plate 11;

[0028] The moving column 6 is guided and limited by the guiding groove to ensure the stability of the moving column 6 during the movement process.

[0029] As Figures 5-6 shown, a steering component is provided on the slider 3. The steering component includes a gear 12, a rack 13, a sliding plate 14 and a limiting plate 15. The rack 13 is located behind the gear 12, and the rack 13 meshes with the gear 12. The sliding plate 14 is connected to the rack 13 away from the gear 12. The limiting plate 15 is fixed inside the slider 3, and the sliding plate 14 is slidably connected to the limiting plate 15. The sliding plate 14 and the limiting plate 15 can ensure the stability of the movement of the rack 13;

[0030] The gear 12 is connected to the hooking component 4, and the rotation angle of the hooking component 4 is 90 degrees;

[0031] A second electric push rod 16 is provided on one side of the slider 3, and the output end of the second electric push rod 16 is connected to the rack 13;

[0032] In the above technical solution, the second electric push rod 16 drives the rack 13 to move. The movement of the rack 13 meshes with the gear 12, thereby driving the gear 12 to rotate 90 degrees, and then driving the hooking component 4 to rotate 90 degrees, so as to change the hooking direction of the hook 7 on the hooking component 4, which is convenient for hooking and putting down the metal part cleaning rack;

[0033] By limiting the extension length of the second electric push rod 16, the movement distance of the rack 13 is limited, so that the gear 12 can only rotate 90 degrees.

[0034] In this embodiment, preferably, a first driving component 17 is provided on the movable frame 2, and the first driving component 17 drives the slider 3 to slide along the slide rail. The first driving component 17 includes a cylinder;

[0035] A second driving component is provided on the fixing frame 1, and the second driving component drives the movable frame 2 to move horizontally along the fixing frame 1. The second driving component includes a lead screw and a motor;

[0036] The slider 3 is driven to move by the first driving component 17 to indirectly drive the hook component 4 to move up and down, so as to realize the picking and placing of the metal part cleaning rack; the movable frame 2 is driven to move by the second driving component to indirectly drive the hook component 4 to move left and right, so as to realize the transportation of the metal part cleaning rack.

[0037] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
