Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator molding and assembly equipment, in particular to a clamping structure for automatic assembly of a refrigerator back panel molding line. Background Art

[0002] As for the refrigerator back panel forming line, it is used to produce refrigerator back panels of specified shapes and sizes. The forming materials can be VCM, PCM, etc. After processing such as mold punching, bending, and corner wrapping, the material is discharged for refrigerator body assembly.

[0003] The existing refrigerator body assembly process relies on automated servo equipment for positioning and transportation. However, the refrigerator back panel itself is large in size, and the general servo mechanical claw structure is difficult to meet its positioning requirements. In addition, the refrigerator back panel needs to be turned over during the assembly process. Therefore, we propose a clamping structure for the automated assembly of the refrigerator back panel forming line to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art. The utility model proposes a clamping structure for the automatic assembly of a refrigerator back panel forming line, which can not only clamp the refrigerator back panel but also turn it over.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a clamping structure for the automatic assembly of the refrigerator back panel forming line, comprising: a base, slide rails symmetrically arranged on both sides of the base, a clamping platform slidably connected to the slide rails and a linkage component. The two clamping platforms are symmetrically arranged with respect to the center of the base, and a flip component is also provided on the top. The linkage component comprises a gear, a rack corresponding to each clamping platform and a servo cylinder. The gear is rotatably connected to the center of the base and is coaxially fixed to an external drive motor on the back of the base. The rack and the servo cylinder each include two and are arranged parallel to the slide rails. One side of the rack tooth groove is meshed with the gear, and its back side is connected to the bottom of the clamping platform through a connecting platform. The output end of the servo cylinder is embedded and fixed with the clamping platform through a connecting shaft, and its back end is hinged to the other clamping platform through a hinge platform.

[0006] Furthermore, each of the clamping platforms includes a base plate, a slider, a heightening plate and a protective plate. The bottom surface of the base plate is slidably connected to the slide rail through the slider. The heightening plate is vertically fixed to the top surface of the base plate. The heightening plates on the two clamping platforms are relatively arranged with the gear as the center. The protective plates are fixedly mounted on both sides of the heightening plates and are exposed to form a hollow clamping opening. The flip assembly is fixed on the top of the heightening plate and is located in the clamping opening.

[0007] Furthermore, the flip assembly includes two turntables, a servo motor and two synchronous shafts. The two turntables are respectively fixed on the top of the two height-increasing plates. The two synchronous shafts are coaxially fixed in each turntable. The servo motor is connected and fixed to the back of the height-increasing plate and the output end is coaxially fixed to one of the synchronous shafts. The opposite ends of the two synchronous shafts are fixed to the external clamping block.

[0008] Furthermore, the output stroke of the servo cylinder is not less than the length setting of the rack.

[0009] Furthermore, fixed-point external bosses are fixed on both sides of the bottom surface of the base.

[0010] Compared with the existing technology, the beneficial effects of the present invention include: through the servo cylinder and the two clamping tables linked by gears and racks, the refrigerator back panel can be repeatedly clamped, and then the clamping and positioning of the refrigerator back panel can be achieved by relying on the synchronous shaft and the external clamping block. The refrigerator back panel can then be flipped through the flipping table, which greatly improves the assembly efficiency in the refrigerator back panel forming line.

[0015] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are only illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.

[0016] According to one embodiment of the present invention, Figure 1-Figure 2 Shown.

[0017] like Figure 1 As shown, for the overall structure, a clamping structure for the automated assembly of a refrigerator back panel molding line includes: a base 1, slide rails 2 symmetrically arranged on both sides of the base 1, a clamping platform 3 slidably connected to the slide rails 2, and a linkage assembly 4. The two clamping platforms 3 are symmetrically arranged with respect to the center of the base 1, and a flip assembly 5 is also provided on the top. The linkage assembly 4 includes a gear 6, a rack 7 corresponding to each clamping platform 3, and a servo cylinder 8. The gear 6 is rotatably connected to the center of the base 1 and is coaxially fixed to the external drive motor 20 on the back of the base 1. The rack 7 and the servo cylinder 8 each include two and are arranged parallel to the slide rail 2. The tooth groove of the rack 7 meshes with the gear 6, and its back is connected to the bottom of the clamping platform 3 through a connecting platform 21. The output end of the servo cylinder 8 is embedded and fixed to the clamping platform 3 through a connecting shaft 9, and its back end is hinged to the other clamping platform 3 through a hinge platform 10. Furthermore, the output stroke of the servo cylinder 8 is not less than the length of the rack 7. Fixed-point external bosses 19 are also fixed on both sides of the bottom surface of the base 1.

[0018] In this embodiment, each of the clamping platforms 3 includes a base plate 11, a slider 12, a heightening plate 13 and a protective plate 14. The bottom surface of the base plate 11 is slidably connected to the slide rail 2 through the slider 12. The heightening plate 13 is vertically fixed to the top surface of the base plate 11. The heightening plates 13 on the two clamping platforms 3 are relatively arranged with the gear 6 as the center. The protective plate 14 is fixedly mounted on both sides of the heightening plate 13 and is exposed to form a hollow clamping opening 15. The flip assembly 5 is fixed on the top of the heightening plate 13 and is located in the clamping opening 15.

[0019] As for the flip assembly 5, it includes two turntables 16, a servo motor 17 and two synchronous shafts 18. The two turntables 16 are respectively fixed on the top of the two height-increasing plates 13. The two synchronous shafts 18 are coaxially fixed in each turntable 16. The servo motor 17 is connected and fixed to the back of the height-increasing plate 13 and the output end is coaxially fixed with one of the synchronous shafts 18. The opposite ends of the two synchronous shafts 18 are fixed to the external clamping block.

[0020] Through the above structure, in the refrigerator back panel forming line, the above linkage component 4 cooperates with the two clamping tables 3 to clamp and position the refrigerator back panel, and then the flipping component 5 flips the refrigerator back panel for assembly, thereby automatically realizing the assembly line-style refrigerator forming operation. Specifically, for the clamping process, the servo output of the drive motor 20 drives the gear 6 to rotate, and then the two racks 7 engaged with the gear 6 can be transmitted to the clamping table 3 through the connecting table 21. The clamping table 3 slides relative to the slide rail 2. In order to ensure that the sliding amplitude is controlled, the servo cylinder 8 in the linkage component 4 can control the relative sliding distance of the two clamping tables 3 through the air rod stroke, and then cooperate with the synchronous shaft 18 on the top of the raising plate 13 to perform hollow clamping and positioning of the refrigerator back panel. The actual structure of the corresponding external clamping block can be multiple, which is not shown in the accompanying drawings.

[0021] Similarly, after the synchronous shaft 18 cooperates with the external clamp to clamp and position the refrigerator back panel, it can be flipped through the flip component 5, that is, the servo output of the servo motor 17 drives the synchronous shaft 18 to position and rotate in the turntable 16. The rotation amplitude is fixed-point, including 90° or 180 degrees, which is convenient for subsequent assembly line-style assembly operations.

[0022] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the scope of protection of the present invention.
