Description

Technical Field

[0001] This utility model relates to the technical field of wheel hub production equipment, specifically to a wheel hub transfer device for a painting line. Background Technology

[0002] The wheel hub is a crucial component of a vehicle, consisting of the rotating part of the wheel core connected to the inner rim of the tire via a pillar. During production, after the wheel hub is formed, its surface is painted on a painting line. Due to the multiple painting processes involved, the wheel hub needs to be transferred to the next painting line after each painting process. As retail products for the market, the wheel hubs have complex and diverse structures and designs. To meet the needs of different car models and styles, the center hole size of retail products varies from 54mm to 110mm in diameter. Existing equipment and operating methods cannot accommodate all products, requiring manual transfer to meet production needs. This results in low production efficiency and safety hazards. Furthermore, during manual transfer, the paint mist environment poses a significant health hazard, requiring the wearing of respirators. Manual transfer also increases the risk of dirt falling onto the wheel hub surface and damage from impacts, leading to a higher product defect rate.

[0003] Therefore, how to design a transfer device that can be applied to various types of wheel hubs and can realize automated transfer functions has become an urgent technical problem to be solved in this field. Utility Model Content

Detailed Implementation

[0028] To enhance understanding of this utility model, it will be further described in detail below with reference to embodiments and accompanying drawings. This utility model can be implemented in the following ways:

[0029] Reference Figure 1-6 A painting line hub transfer device includes a robotic arm 1 and a pick-and-place rack 2 movably disposed below the robotic arm 1.

[0030] The robotic arm 1 has a slide 3 at its free end; the slide 3 is equipped with a sliding drive source 4 that drives the pick-and-place frame 2 to reciprocate at the bottom of the slide 3; the robotic arm 1 is located on the sides of the two painting lines, and the robotic arm 1 can move laterally and longitudinally, thereby driving the slide 3 to move laterally and longitudinally.

[0031] To enable the wheel hub picking and placing function, the bottom of the picking and placing frame 2 is equipped with several linearly distributed transfer fixtures 5. This embodiment uses three transfer fixtures 5, allowing multiple wheel hubs 6 to be transferred in a single line-turning action, further improving production efficiency and reducing production costs. The transfer fixtures 5 employ a mechanical gripper telescopic design. Specifically, the transfer fixture 5 includes a telescopic gripper 51 for clamping the wheel hub 6 and a telescopic drive source 52 for controlling the extension and retraction of the telescopic gripper 51. The telescopic gripper 51 is located at the free end of the transfer fixture 5. Above and below the telescopic drive source 52 are connecting plates 53 connected to the picking and placing frame 2 and connecting parts 54 for mounting the telescopic gripper 51, respectively. The telescopic drive source 52 is a telescopic cylinder. The telescopic cylinder directly extends the gripper head to open and close. The diameter of the gripper head of the telescopic gripper 51 is in the range of 35-40mm, allowing the gripper head of the telescopic gripper 51 to extend into the center hole of any type of wheel hub 6. The telescopic gripper 51 described in this embodiment has a gripper head diameter of 38mm, which can meet the conversion requirements of all products.

[0032] To enable the pick-and-place frame 2 to accommodate multiple transfer fixtures 5, the pick-and-place frame 2 includes a main rod 21 and several protective rods 22 perpendicular to the main rod 21. The transfer fixtures 5 are installed at the bottom of the main rod 21. In this embodiment, the three transfer fixtures 5 are evenly distributed in a straight line at the bottom of the main rod 21. The positions of the protective rods 22 correspond one-to-one with the positions of the transfer fixtures 5. Protective vertical rods 23 extend downwards from both ends of the protective rods 22. The protective vertical rods 23 reduce the risk of the wheel hub 6 being bumped during the transfer process. A wheel hub detector 7 is provided on the inner side of the free end of the protective vertical rod 23. The wheel hub detector 7 is electrically connected to the telescopic drive source 52. The wheel hub detector 7 feeds back the signal indicating that the wheel hub 6 is in position to the telescopic drive source 52, controlling the telescopic drive source 52 to drive the telescopic gripper 51 to pick up and place the wheel hub 6.

[0033] Furthermore, sliding rails 31 are provided on both sides of the bottom of the slide block 3. The pick-and-place rack 2 transfers the wheel hub 6 from one painting line to another by slidingly connecting to the sliding rails 31. Specifically, a sliding connector 24 is provided on the top of the pick-and-place rack 2, which is slidably connected to the sliding rails 31. The sliding connector 24 includes a mounting plate 241 and sliders 242 provided on both sides of the top of the mounting plate 241. The sliders 242 are slidably connected to the sliding rails 31. The sliding drive source 4 can control the sliders 242 of the mounting plate 241 to reciprocate along the sliding rails 31, thereby driving the pick-and-place rack 2 to transfer from one painting line 8 to another painting line 8, realizing the rotation of the wheel hub 6.

[0034] Working principle: The robot arm 1 controls the pick-and-place rack 2 to move to the transfer line position, and then controls the slide 3 to descend. When the wheel hub detector 7 detects that the transfer fixture 5 has penetrated into the center hole of the wheel hub 6, the telescopic drive source 52 controls the gripper head of the telescopic gripper 51 to open, thereby clamping the wheel hub 6. Then the robot arm 1 controls the slide 3 to rise, and the sliding drive source 4 drives the pick-and-place rack 2 to slide along the sliding track 31 of the slide 3 to above another painting line 8. Then the slide 3 descends to the designated position, and the telescopic drive source 52 controls the gripper head of the telescopic gripper 51 to close, so that the wheel hub 6 disengages from the transfer fixture 5 and rotates to the support fixture 81 of the other painting line 8. Then it resets and repeats the above operation.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
