AI Technical Summary
In camera manufacturing, when a robotic arm grasps a precision ceramic substrate, friction caused by misalignment generates debris, affecting product yield and optical performance. This friction is particularly severe when there are errors in product recognition.
Design a support plate structure including a positioning groove and a clearance groove. The depth of the positioning groove is less than the thickness of the product, so that the upper part of the product is located in the clearance groove, avoiding friction between the incoming material gripping arm and the inner wall of the positioning groove. The risk of friction is reduced by the stepped structure and anti-collision groove design.
It effectively avoids debris generated by friction, improves product yield, and ensures the accuracy of product identification and optical performance.

TECHNICAL FIELD
[0001] The utility model relates to a buffer disc technical field, concretely is a bearing disc structure. BACKGROUND
[0002] In camera manufacturing, the disc body is a platform for transferring precise ceramic substrates in the equipment. When the mechanical arm picks up the precise ceramic substrate and places it on the disc body, if the mechanical arm is offset, it will touch the inner wall of the disc body. The inner wall will rebound a force to the mechanical arm and the ceramic substrate. There is a gap between the mechanical arm and the ceramic substrate, which will cause friction, thereby generating substrate debris. The operation of the mechanical arm relies on vacuum, suction (suck product), and blowing (blow product). The blowing airflow will cause the debris generated by friction to scatter on the product, making the product a defective product. Optical products are particularly sensitive to dust, and any debris generated by friction will reduce the yield of the product. In product recognition (PR), the incoming material pickup arm does not touch the bearing disc. However, as shown in the drawings, when there is an error in product recognition, the incoming material pickup arm 8 will touch the bearing disc, and there will be friction between the incoming material pickup arm 8 and the bearing disc, thereby generating debris. The debris affects the pixel recognition function of the optical product. Figure 6 INVENTION CONTENTS The utility model provides a bearing disc structure.

[0025] The preferred embodiments of the present application will be described below with reference to the drawings, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present application, and are not used to limit the present application.
[0026] Embodiment: as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the present application provides a kind of bearing disc structure for protecting ceramic substrate to reduce friction, including disc body 1, the upper surface of disc body 1 is equipped with multiple positioning groove 2 with the rotation center of disc body 1 as center and is positioned to product 10, and the upper portion of positioning groove 2 is equipped with avoiding groove 3 for moving adjusting incoming material grabbing arm 8, the depth H of positioning groove 2 is less than the thickness D of the product 10 positioned, so that the upper portion of the product 10 positioned is located in avoiding groove 3.In product identification error, incoming material grabbing arm 8 will move left and right, but due to the height of the bearing disc beside is lower than the height of incoming material grabbing arm 8 placing ceramic substrate, incoming material grabbing arm 8 touches the inner wall of positioning groove 2, and there will be no friction between incoming material grabbing arm 8 and the inner wall of positioning groove 2, thereby avoiding the generation of debris.
[0027] Multiple positioning grooves 2 are equally divided with the rotation center of disc body 1 as center, so that it is convenient to take and place material.
[0028] Avoiding groove 3 and positioning groove 2 are in stepped structure.
[0029] The specification size of avoiding groove 3 is greater than the specification size of positioning groove 2, so that in product 10 identification error, incoming material grabbing arm 8 will move left and right, but due to the height of the bearing disc beside is lower than the height of incoming material grabbing arm 8 placing ceramic substrate, incoming material grabbing arm 8 touches the inner wall of positioning groove 2, and there will be no friction between incoming material grabbing arm 8 and the inner wall of positioning groove 2, thereby avoiding the generation of debris.
[0030] The inner contour of the positioning groove 2 is matched with the outer contour of the ceramic substrate of the product 10 to be positioned, and the two sides of the positioning groove 2 are provided with the notches 4 which are communicated with the positioning groove 2. In this way, when some products 10 cannot be sucked up due to the problem of warping deformation, the product 10 can be clamped by using the tweezers through the notches 4, and manual operation is facilitated.
[0031] The anti-collision gap 9 is left between the positioning groove 2 and the ceramic substrate of the product, so as to play an anti-collision role.
[0032] The anti-collision groove 5 is arranged in a stepped manner with the avoidance groove 3 at the top of the positioning groove 2, so as to avoid the inner wall of the positioning groove 2 being touched by the incoming material grabbing arm.
