[0002] The sunroof primer coating process is a crucial step in automobile manufacturing, involving pretreatment of components such as the sunroof glass and frame before bonding. As a pretreatment agent, the primer significantly improves the surface activity of the substrates, enhancing the adhesion of subsequent adhesives and ensuring a strong bond between sunroof components. In the sunroof primer coating process, after the primer is applied, it needs to be transferred using equipment. Current transfer methods rely on manual inspection and handling, and additional manual inspection of the primer-coated areas is required, resulting in low efficiency. Utility Model Content

Detailed Implementation

[0024] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] See Figures 1-7 A sunroof primer unloading mechanism includes a frame 10 and a rotating disk 210 driven by a rotary motor mounted on the frame. A support rod 220 is fixed on the rotating disk 210, and a suction cup seat 221 is fixed on the support rod 221. A first suction cup 222 for mounting the sunroof is fixed on the suction cup seat. A pair of movable slides 230 are provided on both sides of the frame 10. A lifting mechanism is fixed to the movable end of each movable slide 230. A lifting plate 250 is fixed to the output end of the lifting mechanism. A second suction cup 251 is fixed to the lifting plate. One end of the frame 10 extends into a chamber 102. A camera 30 for detecting the primer liquid area is located at the top of the chamber 102.

[0026] One end of the platform 10 extending into the chamber 102 is fixed with an image fixing plate located below the acquisition camera. A support platform 40 is fixed on the upper surface of the image fixing plate, and a suction cup fixing seat 410 is fixed on the support platform. Multiple third suction cups 420 are fixed on the upper surface of the suction cup fixing seat.

[0027] In this embodiment, the lifting mechanism is a lifting cylinder 240. A rotary motor is fixed on the platform 10 and located below the rotating disk 210 to drive the rotating disk 20 to rotate. In the initial state, the skylight is placed above the first suction cup 222, and the primer coating equipment is located on one side of the rotating disk. The rotating disk 210 is fixedly connected to the output end of the rotary motor. After the skylight on the rotating disk 210 completes the primer coating on one side, the rotating disk 210 rotates 180° under the drive of the rotary motor, and then completes the primer coating on the other side of the skylight. Then, the movable end of the moving slide 230 is located on both sides of the rotating disk of the moving slide 230. The lifting plate 250 is raised under the drive of the lifting cylinder 240, and the second suction cup 251 is also raised synchronously. When the second suction cup 251 is higher than the first suction cup 222, the skylight is supported by the second suction cup 251 and detached from the first suction cup 222. Then, the moving slide 230 drives the skylight to move into the cabin, where the acquisition camera 30 in the cabin performs visual camera acquisition and comparison.

[0028] One end of the platform 10 extending into the cabin 102 is fixed with an image fixing plate located below the acquisition camera. A support platform 40 is fixed on the upper surface of the image fixing plate, and a suction cup fixing seat 410 is fixed on the support platform. Multiple third suction cups 420 are fixed on the upper surface of the suction cup fixing seat. After the moving slide 230 moves the skylight into the cabin, the moving slide 230 moves the skylight above the support platform 40. Then, the lifting plate 250 descends under the drive of the lifting mechanism. When the second suction cup 251 descends, the skylight located on the second suction cup 251 is supported by the third suction cups 420. Then, the acquisition camera 30 in the cabin performs visual camera acquisition and judges whether the base coat area meets the preset requirements based on visual recognition.

[0029] In actual implementation, the primer is generally black or colored to facilitate identification by the camera 30. The chamber 102 also has an auxiliary light source for illumination, which can be designed above the chamber 102 or on the support platform 40.

[0030] In this embodiment, the first suction cup 222, the second suction cup 251, and the third suction cup 420 are all connected to a negative pressure pump via pipelines. After placement in the sunroof, they can effectively absorb air using negative pressure.

[0031] In one embodiment of the present invention, a discharge robotic arm 50 is provided on the other side of the chamber 102. The movable end of the discharge robotic arm 50 is fixed with a clamp 510 for holding glass. An output suction cup 520 is fixed on the clamp 510. A light source and a marking camera 521 for taking pictures of glass markings are also fixed on the clamp. A protective cover is fixed on the outside of the marking camera 521.

[0032] During operation, the output suction cup 520 is connected to a negative pressure pump through a pipeline, and the marking camera 521 is used to identify the markings on the sunroof glass, thereby recording the sunroof glass that has completed the primer inspection.

[0033] In one embodiment of this utility model, a discharge storage rack 60 is also provided beside the discharge robotic arm. The discharge storage rack 60 includes a base frame 601 and a vertical frame 610 fixed to the rear side of the base frame. A pair of support rods 620 facing the discharge robotic arm are fixed on the vertical frame. Discharge guide seats 630 are provided on both sides of the base frame, and guide wheels 631 are provided on the inner side of the discharge guide seats for guidance. The guide wheels 631 are used to facilitate the insertion and guidance of the discharge storage rack 60, and the support rods 620 are used to receive the sunroof glass transferred from the discharge robotic arm 50.

[0034] A baffle 70 is fixed to the front of the discharge guide seat 630, and a corner-pressing cylinder 710 fixed to the guide seat is provided next to the baffle 70. The corner-pressing cylinder 710 is used to lock the storage rack 60 to prevent it from moving during the placement of the skylight.

[0035] In order to apply additional primer to sunroofs that do not meet the standards detected by the acquisition camera, a rework platform 80 is provided on the side of the discharge robotic arm. A rework rotary cylinder is fixed on the upper part of the rework platform 80. The rotating end of the rework rotary cylinder 810 is fixedly connected to the rework platform. A rework negative pressure suction cup 820 is fixed on the upper surface of the rework platform 810. The working mode of the rework platform 810 is similar to that of the rotating disk 210. After the rework negative pressure suction cup 820 adsorbs the sunroof, the rotary cylinder 810 drives the sunroof glass to rotate, thereby meeting the operation of manually applying primer.

[0036] The above description is only an embodiment of this utility model. The unloading robotic arm described herein is a commercially available multi-axis (at least 5-axis) robotic arm that can meet basic lifting, translation, and rotation capabilities. Any equivalent structural or process transformations made using the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
