Description

Technical Field

[0001] This utility model relates to the field of refrigerator back panel manufacturing technology, specifically to an integrated device for drawing and bending refrigerator back panels. Background Technology

[0002] In the modern home appliance industry, refrigerators are an indispensable appliance in family life, and their market demand remains strong. The refrigerator back panel, as an important component of the refrigerator, plays a key role in the overall structural stability, heat dissipation performance, and protection of internal components.

[0003] In the manufacturing process of refrigerator back panels, bending and drawing are two key processes. Bending allows the back panel to be formed into the required shape and angle to adapt to the overall structure of the refrigerator; drawing can change the thickness of the back panel, improve its strength and rigidity, and also improve the surface quality of the back panel.

[0004] In the traditional refrigerator back panel manufacturing process, bending and drawing are usually carried out in separate steps and require different equipment. After the drawing process is completed, the back panel needs to be removed from the drawing machine and transferred to the bending machine by manual or mechanical handling. This process not only consumes additional time and labor costs, but also easily causes collisions, scratches and other damage to the back panel during handling, affecting the appearance quality of the product, and the work efficiency is low.

[0005] Therefore, in order to address the above problems, the applicant needs to design an integrated drawing and bending device for the refrigerator back panel to solve the problem. Utility Model Content

[0006] The purpose of this invention is to provide an integrated device for drawing and bending a refrigerator back panel, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an integrated device for drawing and bending a refrigerator back panel, comprising a base, and a clamping robot arm for clamping and drawing the refrigerator back panel is provided above the base.

[0008] It also includes: a bending mechanism disposed above the base, the bending mechanism being used to bend the refrigerator back panel, the bending mechanism comprising a base, a support plate fixedly disposed on the base, a rotating roller disposed on the support plate, a fixed frame fixedly disposed on the support plate, a hinge disposed on the fixed frame, a rotating frame disposed on the hinge, a control component disposed on the rotating frame, the control component being used to drive the rotating frame to rotate, a second bearing seat fixedly disposed on the rotating frame, and a second fixed shaft disposed inside the second bearing seat.

[0009] Furthermore, a clamping component is fixedly installed on the fixing frame, and the clamping component is used to clamp the back panel of the refrigerator. The clamping component includes a stabilizing base fixedly connected to the fixing frame, and a connecting rod is fixedly installed on the stabilizing base. A reinforcing plate is fixedly installed at the end of the connecting rod away from the stabilizing base, and a second cylinder is fixedly installed on the reinforcing plate. A clamping plate is installed at the output end of the second cylinder, and the clamping plate cooperates with the stabilizing base to lock the back panel of the refrigerator.

[0010] Furthermore, a first bearing seat is fixedly installed on the fixing frame, and a first fixed shaft is installed inside the first bearing seat.

[0011] Furthermore, a fixing component is fixedly installed below the fixing frame, and the fixing component is fixedly connected to the base.

[0012] Furthermore, the lifting component includes a rotating sleeve fixedly connected to the rotating frame, an extension is rotatably disposed on the rotating sleeve, and a cylinder is fixedly disposed below the extension.

[0013] Furthermore, a connecting member is rotatably provided at the end of the cylinder away from the extension member, and the connecting member is fixedly connected to the base.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the integrated drawing and bending device for refrigerator back panels can draw and bend the substrate used to manufacture refrigerator back panels, with high work efficiency, as detailed below:

[0015] When using this integrated refrigerator back panel drawing and bending device, the refrigerator back panel substrate bed is passed through the clamping component and above the first and second fixed shafts. A clamping robot grips one end of the refrigerator back panel. After clamping, cylinder two is activated, which moves the clamping plate to securely hold the substrate. Then, the clamping robot draws the refrigerator back panel substrate. After the substrate is drawn, cylinder one is activated, which pushes the extension piece. The extension piece moves using a rotating sleeve, which in turn moves a rotating frame. The rotating frame uses the first fixed shaft, the second fixed shaft, and the rotating roller to bend the refrigerator back panel substrate, thereby enabling the drawing and bending of the substrate used to manufacture the refrigerator back panel and improving work efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, this utility model discloses an integrated device for stretching and bending a refrigerator back panel, comprising a base 1, and a gripping robot 10 for gripping and stretching the refrigerator back panel is provided above the base 1. It also includes a bending mechanism 2 provided above the base 1, which is used to bend the refrigerator back panel. The bending mechanism 2 includes a base 20, a support plate 21 fixedly mounted on the base 20, a rotating roller 22 mounted on the support plate 21, a fixing frame 23 fixedly mounted on the support plate 21, a hinge 24 mounted on the fixing frame 23, a rotating frame 25 mounted on the hinge 24, a control component mounted on the rotating frame 25, and a second bearing seat 26 fixedly mounted on the rotating frame 25, with a second fixed shaft 27 disposed within the second bearing seat 26.

[0023] A clamping component 29 is fixedly installed on the fixing frame 23, and the clamping component 29 is used to clamp the back panel of the refrigerator. The clamping component 29 includes a stabilizing base 290 fixedly connected to the fixing frame 23, and a connecting rod 291 is fixedly installed on the stabilizing base 290. A reinforcing plate 292 is fixedly installed at the end of the connecting rod 291 away from the stabilizing base 290, and a cylinder 293 is fixedly installed on the reinforcing plate 292. A clamping plate 294 is installed at the output end of the cylinder 293, and the clamping plate 294 cooperates with the stabilizing base 290 to lock the back panel of the refrigerator. Through the linkage structure formed by the stabilizing base 290, the connecting rod 291, the reinforcing plate 292 and the cylinder 293, the back panel of the refrigerator can be directly fixed and clamped after the drawing process, without the need for manual or mechanical handling. The locking design of the clamping plate 294 and the stabilizing base 290 effectively avoids the collision and scratch damage caused by handling in traditional processes, while reducing the process changeover time and significantly improving the processing efficiency and product surface quality consistency.

[0024] A first bearing seat 230 is fixedly installed on the fixed frame 23, and a first fixed shaft 231 is installed inside the first bearing seat 230. By enhancing the rotational support stability of the fixed frame 23, the axial positioning accuracy of the rotating frame 25 during the bending process is ensured. This solves the problem of bending angle deviation caused by positioning errors between equipment in the traditional step-by-step process, improves the adaptability of the back panel to the overall structure of the refrigerator, and extends the service life of key components of the device.

[0025] A fixing member 232 is fixedly installed below the fixing frame 23, and the fixing member 232 is fixedly connected to the base 20, which significantly improves the overall rigidity of the bending mechanism 2 when subjected to the combined load of drawing and bending, effectively suppresses vibration and deformation during processing, and has strong stability.

[0026] The lifting component includes a rotating sleeve 282 fixedly connected to the rotating frame 25. An extension 281 is rotatably mounted on the rotating sleeve 282, and a cylinder 280 is fixedly mounted below the extension 281. Through the rotational cooperation between the rotating sleeve 282 and the extension 281, and the extension and retraction drive of the cylinder 280, the height of the rotating frame 25 can be adjusted in a controllable manner. This allows a single machine to adapt to the bending curvature requirements of back panels of different specifications, greatly improving the flexible production capability of the equipment while ensuring processing accuracy.

[0027] A connector 28 is rotatably provided at the end of cylinder 280 away from extension 281, and connector 28 is fixedly connected to base 20. Connector 28 facilitates support of cylinder 280 to make the pressure distribution more uniform during bending, which reduces energy consumption and avoids damage to the back plate material caused by local stress concentration.

[0028] Working principle: When using this integrated refrigerator back panel drawing and bending device, the refrigerator back panel substrate bed is passed through the clamping component 29 and above the first fixed shaft 231 and the second fixed shaft 27. The clamping robot 10 clamps one end of the refrigerator back panel. After clamping, cylinder 293 is activated, which drives the clamping plate 294 to move. The clamping plate 294 firmly clamps the substrate. Then, the clamping robot 10 draws the refrigerator back panel substrate. After the substrate is drawn, cylinder 280 is activated, which pushes the extension 281. The extension 281 moves using the rotating sleeve 282, which drives the rotating frame 25 to move. The rotating frame 25 bends the refrigerator back panel substrate using the first fixed shaft 231, the second fixed shaft 27, and the rotating roller 22. This allows for the drawing and bending of the substrate used to manufacture the refrigerator back panel, improving work efficiency.
