Description

Technical Field

[0001] This utility model relates to the field of refrigerator outer box assembly, and in particular to a positioning tool for refrigerator outer box assembly. Background Technology

[0002] In the refrigerator manufacturing process, the outer casing assembly is one of the key steps to ensure the integrity and quality of the refrigerator product. The outer casing not only protects the internal structure of the refrigerator but also has a significant impact on the product's appearance and transportation safety. Current refrigerator outer casing assembly typically involves placing the refrigerator on a conveyor belt, transporting it via the belt, and then using a robotic arm to grab the outer casing and fit it onto the refrigerator. However, current equipment can only achieve simple transport of the refrigerator and struggles to achieve proper centering. If the refrigerator is initially misaligned, it will also shift during transport. Furthermore, due to equipment instability or other external factors, the refrigerator may also shift during transport, affecting the outer casing assembly and leading to reduced assembly efficiency and quality.

[0003] Therefore, it is necessary to design a positioning fixture for refrigerator outer box assembly that can transport the refrigerator for centering and positioning, and then automatically pick up the outer box for assembly, to prevent positional deviation from affecting the assembly of the outer box, and improve assembly efficiency and quality. Utility Model Content

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0019] A positioning fixture for assembling the outer casing of a refrigerator, such as Figures 1-5 As shown, it includes a first support frame 1, a first conveyor belt 2, a second support frame 3, a placement rack 4, an adsorption component, and a positioning component. The first support frame 1 is equipped with the first conveyor belt 2 on its upper part, the second support frame 3 is connected to the upper side of the first support frame 1, and the placement rack 4 is connected to the rear of the first support frame 1. The second support frame 3 is equipped with an adsorption component for adsorbing the outer box of the refrigerator, and the first support frame 1 is equipped with a positioning component for centering the refrigerator.

[0020] like Figures 1-3 As shown, the adsorption assembly includes a trackless cylinder 5, a first sliding frame 6, an electric push rod 7, a mounting frame 8, and suction cups 9. The front of the second support frame 3 is connected to two trackless cylinders 5 on the left and right. The trackless cylinders 5 and the processor are electrically connected through a control module. The first sliding frame 6 is connected between the sliders of the trackless cylinders 5. The electric push rods 7 are connected to both the left and right sides of the first sliding frame 6. The electric push rods 7 and the processor are electrically connected through a control module. The mounting frame 8 is connected between the telescopic ends of the electric push rods 7. Four suction cups 9 are connected to both the left and right sides of the mounting frame 8.

[0021] like Figure 1 , Figure 4 and Figure 5As shown, the positioning assembly includes rollers 10, a second sliding frame 11, a second conveyor belt 12, a pressing block 13, a rack 14, a gear 15, a guide rod 16, and a telescopic spring 17. The lower part of the first sliding frame 6 is rotatably connected to the rollers 10, which are made of rubber and have good wear resistance. The front and rear parts of the first support frame 1 are slidably connected to the second sliding frames 11. Two second conveyor belts 12 are installed on the upper part of each second sliding frame 11. The middle part of the front second sliding frame 11 is connected to... There is a compression block 13, which is trapezoidal to facilitate compression and movement. The lower part of the second sliding frame 11 is connected to a rack 14. The middle part of the first support frame 1 is rotatably connected to a gear 15. The rack 14 meshes with the gear 15. The left and right sides of the first support frame 1 are connected to guide rods 16. The guide rods 16 are slidably connected to the front of the second sliding frame 11. The guide rods 16 are all T-shaped to facilitate guidance. The guide rods 16 are connected to the front of the second sliding frame 11 by a telescopic spring 17.

[0022] When assembling the refrigerator outer casing, this device can be used to bring the first support frame 1 into contact with the ground, place the outer casing on the placement rack 4, then place the refrigerator on the first conveyor belt 2, and then start the first conveyor belt 2 to transport the refrigerator. The refrigerator is then placed on the first conveyor belt 2 for further transport. Simultaneously, the processor activates the trackless cylinder 5 via the control module, causing the slider on the trackless cylinder 5 to move, which in turn moves the first sliding frame 6, causing the roller 10 to move and press the pressing block 13, which in turn moves the front second sliding frame 11 along the guide rod 16. The telescopic spring 17 is stretched, causing the corresponding rack 14 to move. The front rack 1... The roller 10 meshes with gear 15, causing gear 15 to rotate. Gear 15 meshes with the rear rack 14, driving the rear second sliding frame 11 to move, thus moving the second conveyor belt 12 and centering the refrigerator. The extrusion block 13 is trapezoidal, and the guide rods 16 are all T-shaped. When the roller 10 disengages from the extrusion block 13, the telescopic spring 17 rebounds, and the front second sliding frame 11 moves back to its original position, causing the front rack 14 to move back to its original position. The front rack 14 meshes with gear 15, causing gear 15 to rotate. Gear 15 meshes with the rear rack 14, driving the rear second sliding frame 11 to move back to its original position. The roller 10 is made of rubber. The material has good wear resistance. When the first sliding frame 6 moves to the top, the electric push rod 7 is activated, which drives the mounting frame 8 to move, causing the suction cup 9 to move and contact the outer box. The suction cup 9 is connected to an external vacuum pump to achieve adsorption of the outer box. After adsorption, the electric push rod 7 reverses its operation, causing the mounting frame 8 and suction cup 9 to move and reset, thereby moving the outer box above the first conveyor belt 2. Then, the slider on the trackless cylinder 5 reverses its movement and resets, causing the first sliding frame 6 to move and reset, moving the outer box to fit onto the refrigerator. After the outer box is assembled, the vacuum pump is turned off, so that the suction cup 9 no longer adsorbs the outer box. At the same time, the roller 10 moves and squeezes the second sliding frame 11 to move, and the telescopic spring... Spring 17 is stretched, causing the second conveyor belt 12 to contact the outer box. The refrigerator and outer box are conveyed and discharged through the operation of the first conveyor belt 2 and the second conveyor belt 12. When the roller 10 disengages from the pressing block 13, the telescopic spring 17 rebounds, and the second sliding frame 11 and the second conveyor belt 12 move back to their original positions. The refrigerator continues to be conveyed and discharged through the first conveyor belt 2. The above operation is then repeated to convey, position, and assemble the outer box of the next refrigerator until the assembly is completed. This allows the refrigerator to be automatically picked up and assembled after being centered, preventing positional deviation from affecting the assembly of the outer box, and improving assembly efficiency and quality. After the assembly is completed, the first conveyor belt 2 and the second conveyor belt 12 can be turned off.
