[0002] In the modern home appliance manufacturing industry, refrigerator production has become highly dependent on automated production lines to improve production efficiency and product quality. The pre-assembly process, a crucial step in refrigerator production, primarily involves accurately installing components such as the compressor, evaporator, and condenser onto the refrigerator body.
[0003] In the process of assembling refrigerators, the precise positioning of the cabinet plays a decisive role in the pre-assembly quality and efficiency. If the positioning is inaccurate, it will lead to the installation deviation of parts, affecting the refrigerator's core functions such as cooling performance and sealing, increasing the defect rate, and also reducing the operating efficiency of the production line and increasing production costs. Therefore, it needs to be improved. Utility Model Content

[0028] This utility model provides the following technical solution:
[0029] Example 1
[0030] Please see Figure 1-6 This utility model provides a technical solution: a multi-angle adaptive positioning fixture for a refrigerator pre-assembly production line, including a support column 1, a conveyor table 2 fixedly connected to the top of the support column 1, a lifting and rotating mechanism 5 set in the middle of the top of the conveyor table 2, a pressing mechanism 6 set on the top of the lifting and rotating mechanism 5, a refrigerator body 4 set on the top of the conveyor table 2, a vision sensor 3 fixedly connected to the back end of the top of the conveyor table 2, and an infrared detector 7 set on the inner side of the lifting and rotating mechanism 5.
[0031] The lifting and rotating mechanism 5 includes a lifting component 51 and a rotating component 52. The lifting component 51 is located at the top center of the conveyor table 2, and the rotating component 52 is located at the top of the lifting component 51.
[0032] The lifting assembly 51 includes a support frame 513, which is fixedly connected to the top of the conveyor table 2. An infrared detector 7 is fixedly connected to the inner front side of the support frame 513. A first cylinder 515 is fixedly connected to the top of the support frame 513. A lifting plate 512 is fixedly connected to the bottom of the first cylinder 515. A lifting disk 511 is fixedly connected to the inner side of the lifting plate 512. The lifting disk 511 is slidably connected to the inner side of the support frame 513. A limit rod 514 is fixedly connected to the top of the lifting plate 512.
[0033] Furthermore, there are two limiting rods 514. The two limiting rods 514 are fixedly connected to the top of the lifting plate 512, and the two limiting rods 514 are slidably connected to the inner side of the support frame 513. The limiting rods 514 can limit the lifting plate 512, making the lifting plate 512 more stable during the lifting process.
[0034] Example 2
[0035] Please see Figure 1-6Furthermore, based on Embodiment 1, the rotating assembly 52 further includes a load-bearing frame 528, which is fixedly connected to the top right side of the lifting plate 511. A drive motor 525 is fixedly connected to the top of the load-bearing frame 528, a rotating shaft 526 is fixedly connected to the bottom of the drive motor 525, a drive gear 527 is fixedly connected to the bottom of the rotating shaft 526, a rotating gear 524 is meshed on the left side of the drive gear 527, a rotating cylinder 522 is fixedly connected to the bottom of the rotating gear 524, a second cylinder 523 is fixedly connected to the outside of the rotating cylinder 522, and a protective clamp 521 is fixedly connected to the inside of the second cylinder 523.
[0036] Furthermore, a circular groove corresponding to the movement trajectory of the rotating gear 524 is provided on the inner side of the lifting plate 511, and the rotating gear 524 is rotatably connected to the inside of the circular groove. Through the circular groove, the rotating gear 524 can rotate inside the lifting plate 511, making the rotating gear 524 more stable during rotation.
[0037] Furthermore, there are four second cylinders 523, which are fixedly connected to the front, rear, left, and right sides of the rotating cylinder 522 respectively. Through the four second cylinders 523, the protective clamps 521 can be driven to clamp and fix the refrigerator body 4 on the front, rear, left, and right sides.
[0038] Example 3
[0039] Please see Figure 1-6 Furthermore, based on Embodiment 1, the pressing mechanism 6 includes a fixed frame 61, which is fixedly connected to the top of the lifting plate 511. A third cylinder 62 is fixedly connected to the top of the fixed frame 61, and a protective pressure plate 63 is fixedly connected to the bottom of the third cylinder 62.
[0040] Furthermore, the bottom of the protective pressure plate 63 is made of rubber, and the protective pressure plate 63 is slidably connected to the inside of the lifting plate 511. The protective pressure plate 63 can press and fix the refrigerator body 4, making it more stable when the staff assembles the refrigerator body 4.
[0041] In actual operation, when this device is used, the PLC controller opens the conveyor 2, and the refrigerator body 4 is placed in the middle of the top of the conveyor 2. The refrigerator body 4 is conveyed by the conveyor 2. When the refrigerator body 4 moves to the inside of the support frame 513, the infrared detector 7 detects the position of the refrigerator body 4 and transmits the signal to the PLC controller, so that the PLC controller transmits the signal to the conveyor 2, so that the conveyor 2 stops operating.
[0042] After the conveyor 2 stops operating, the PLC controller activates the vision sensor 3, which collects the position and angle of the refrigerator body 4. The collected image is digitized by the image acquisition unit and processed by the vision software. The result information is then transmitted to the PLC controller. When the result information indicates that the position of the refrigerator body 4 needs to be rotated and adjusted, the PLC controller activates the first cylinder 515, which drives the lifting plate 511 to move downward through the lifting plate 512. The lifting plate 511 then drives the rotating cylinder 522 to move to the periphery of the refrigerator body 4. The PLC controller then activates the second cylinder 523, which drives the protective clamp 521 to move, allowing the protective clamp 521 to clamp the refrigerator body 4.
[0043] After clamping the refrigerator body 4, the PLC controller turns on the drive motor 525, which drives the drive gear 527 to rotate via the rotating shaft 526. The drive gear 527 then drives the rotating cylinder 522 and the second cylinder 523 to rotate via the rotating gear 524. The second cylinder 523 then drives the refrigerator body 4 to rotate via the protective clamp 521, allowing the refrigerator body 4 to rotate 180 degrees back and forth. This adjusts the position of the refrigerator body 4, ensuring it is aligned correctly. After adjusting the position, the clamping of the refrigerator body 4 is released, and the PLC controller turns on the third cylinder 62, which moves the protective pressure plate 63 downward. This allows the protective pressure plate 63 to press and fix the refrigerator body 4, making it more stable for workers to assemble. Infrared detector 7 model: Visual sensor 3 model: Omron F250.
