Description

Technical Field

[0001] The utility model belongs to the technical field of assembly machinery, and particularly relates to a door installation and positioning mechanism. Background Art

[0002] In the production and processing of refrigerators, it is necessary to assemble the refrigerator door on the box body. During the assembly, due to the certain weight of the refrigerator door itself, machinery is usually required for the positioning and transportation of the refrigerator door and the box body. After the refrigerator door and the box body are aligned, assembly is carried out.

[0003] The existing alignment devices usually set a fixed position to place the box body, and then hoist the refrigerator door to the top of the box body. During the alignment process, the relative position between the refrigerator door and the box body is usually determined by fine-tuning the refrigerator door conveying device, which has the problem of cumbersome alignment process. At the same time, during the long-term operation, the conveying position of the refrigerator door conveying device is prone to deviation. Since the refrigerator door and the refrigerator body have the same shape, if not discovered in time, there will be the problem of misalignment of the refrigerator door assembly, affecting the aesthetics and even resulting in inability to assemble. Summary of the Utility Model

[0004] In view of the above existing technical problems, the utility model provides a door installation and positioning mechanism to solve the problems of inaccurate alignment and difficulty in discovering deviation existing in the existing refrigerator door assembly and alignment device. The door installation and positioning mechanism can effectively improve the alignment accuracy between the door panel and the box body and timely discover the misalignment situation.

[0005] The utility model provides a door installation and positioning mechanism for the installation and positioning of a box body and a door panel, including a guide rail frame, a door panel stacking mechanism, a box body positioning mechanism, a horizontal guide rail, a horizontal plate, a lifting device, a suction plate and suction cups. The door panel stacking mechanism and the box body positioning mechanism are arranged at intervals below the guide rail frame. The horizontal guide rail is located on the guide rail frame and extends from the door panel stacking mechanism to the box body positioning mechanism. The horizontal plate is arranged on the horizontal guide rail so as to be able to walk horizontally. The lifting device is arranged on the horizontal plate, the bottom of the lifting device is connected to the suction plate, and a plurality of suction cups are arranged below the suction plate. The box body positioning mechanism is provided with a first limiting part and a second limiting part which are arranged at intervals for limiting the box body. The first limiting part is provided with a first infrared transmitting head, and the second limiting part is provided with a second infrared transmitting head. Both the first infrared transmitting head and the second infrared transmitting head face upward. Corresponding to the positions of the first infrared transmitting head and the second infrared transmitting head on the guide rail frame, a first infrared receiving head and a second infrared receiving head are correspondingly arranged.

[0006] Further, a belt and a driving motor are provided on the guide rail frame. The belt extends in a direction parallel to the horizontal guide rail, and the driving motor is used to drive the belt to rotate. The horizontal plate is fixed to the belt.

[0007] Further, the number of the horizontal guide rails is two, and the two horizontal guide rails are arranged in parallel. Both sides of the horizontal plate are slidably arranged on the two horizontal guide rails.

[0008] When the door installation positioning mechanism assembles and positions the door panel and the box body, multiple door panels can be stacked on the top of the door panel stacking mechanism, and the box body is placed between the first limiting part and the second limiting part. The suction plate is moved above the door panel stacking mechanism by the movement of the horizontal plate on the horizontal guide rail. The lifting device drives the suction plate to press down and suck the door panel, and then drives the door panel to rise. Then, the horizontal plate drives the door panel to move to the top of the box body. At this time, if the first infrared receiving head and the second infrared receiving head can receive infrared signals, it means that the door panel and the box body are accurately positioned. If one of the first infrared receiving head and the second infrared receiving head cannot receive the infrared signal, it means that the door panel at least blocks the first infrared transmitting head or the second infrared transmitting head. At this time, the door panel is misaligned. It is necessary to determine whether the walking is not in place or the stroke is too large according to the specific receiving conditions of the first infrared receiving head and the second infrared receiving head, and correspondingly adjust the stroke of the horizontal plate to ensure the accuracy of the positioning of the door panel and the box body.

The door panel stacking mechanism 1 and the box body positioning mechanism 5 are arranged at intervals below the guide rail frame 11. The horizontal guide rail 14 is located on the guide rail frame 11 and extends from the door panel stacking mechanism 1 to the box body positioning mechanism 5. The horizontal plate 12 is arranged on the horizontal guide rail 14 so as to be able to move horizontally. The lifting device 13 is arranged on the horizontal plate 12, and the bottom of the lifting device 13 is connected to the suction plate 10. A plurality of the suction cups 9 are arranged below the suction plate 10. A first limiting part 4 and a second limiting part 6 are arranged on the box body positioning mechanism 5. The first limiting part 4 and the second limiting part 6 are arranged at intervals for limiting the box body 8. A first infrared transmitting head 3 is arranged on the first limiting part 4, and a second infrared transmitting head 7 is arranged on the second limiting part 6. Both the first infrared transmitting head 3 and the second infrared transmitting head 7 face upward. Corresponding to the positions of the first infrared transmitting head 3 and the second infrared transmitting head 7 on the guide rail frame 11, a first infrared receiving head 17 and a second infrared receiving head 18 are correspondingly arranged.

[0015] A belt 15 and a driving motor 16 are arranged on the guide rail frame 11. The belt 15 extends in a direction parallel to the horizontal guide rail 14. The driving motor 16 is used to drive the belt 15 to rotate. The horizontal plate 12 is fixed to the belt 15.

[0016] The number of the horizontal guide rails 14 is 2. The 2 horizontal guide rails 14 are arranged in parallel with each other. The two sides of the horizontal plate 12 are slidably arranged on the 2 horizontal guide rails 14.

Then, the horizontal plate 12 drives the door panel 2 to move to the top of the box body 8. At this time, if the first infrared receiving head 17 and the second infrared receiving head 18 can receive infrared signals, it means that the door panel 2 and the box body 8 are accurately positioned. If either the first infrared receiving head 17 or the second infrared receiving head 18 cannot receive infrared signals, it means that the door panel 2 at least blocks the first infrared transmitting head 3 or the second infrared transmitting head 7. At this time, the situation of misalignment of the door panel 2 occurs. It is necessary to determine whether the walking is not in place or the stroke is too large according to the specific reception of the first infrared receiving head 17 and the second infrared receiving head 18, and correspondingly adjust the stroke of the horizontal plate 12 to ensure the accuracy of the positioning of the door panel 2 and the box body 8.
