Description

Technical Field

[0001] This utility model relates to the field of wafer manufacturing, and in particular to a protective tray for assisting in the replacement of grinding wheels. Background Technology

[0002] Currently, with the increasing thinning of terminal display panels and their growing complexity, the required chips are also becoming thinner to match terminal applications. Wafers from front-end foundries are relatively thick and require grinding to achieve the required final thickness.

[0003] The grinding machine uses grinding wheels to thin and polish products. Based on practical experience, after grinding approximately 20,000 pieces of product, the grinding wheel needs to be replaced with a new spare before continuing operation due to wear and tear. The teeth of the grinding wheel itself are made of diamond particles and adhesive, which are relatively fragile. Because the grinding wheel is heavy and the working space is limited during replacement, it is easily damaged by bumps. Grinding wheels are also expensive, resulting in significant economic losses. If personnel do not notice damage to the grinding wheel teeth in time, there is also a risk to the quality of the product. To solve the above problems, we propose a protective tray to assist in the replacement of grinding wheels. Utility Model Content

[0004] The purpose of this invention is to provide a protective tray for assisting in the replacement of grinding wheels. Its advantage is that it can prevent damage to the teeth of the grinding wheels when replacing them, thereby avoiding economic losses and product risks.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a protective tray for assisting in the replacement of grinding wheels, comprising a base, an electric lifting rod bolted to the top of the base, a mounting seat bolted to the top of the electric lifting rod, a tray on the top of the mounting seat, a slot on the surface of the tray, a mounting rod bolted to the bottom of the tray, the mounting rod slidingly sleeved with the inner wall of the mounting seat, a fixing rod slidingly sleeved with the inner wall of the mounting seat, a fixing hole on the surface of the mounting rod, the fixing hole engaging with one end of the fixing rod, a locking rod slidingly sleeved with the inner wall of the mounting seat, a first spring between one end of the locking rod and the inner wall of the mounting seat, a toggle rod bolted to the surface of the locking rod, and a locking hole on the surface of the fixing rod engaging with the locking rod.

[0006] Using the above technical solution, the slots on the tray engage with the teeth of the grinding wheel. When replacing the grinding wheel, the electric lifting rod moves the tray below the grinding wheel, placing the teeth of the grinding wheel into the slots on the tray. The silicone tray supports and cushions the grinding wheel, eliminating the need for manual handling and preventing potential collisions between the grinding wheel teeth, thus avoiding damage and improving safety. By moving the lever, the locking rod disengages from the locking hole, and the fixing rod disengages from the fixing hole under the action of the first spring. The tray can then be removed for easy replacement, improving practicality.

[0007] The present invention is further configured such that a second spring is sleeved on the surface of the fixing rod.

[0008] By adopting the above technical solution and setting a second spring, it is easy for the fixing rod to disengage from the fixing hole, making it convenient to use.

[0009] The present invention is further configured such that one end of the snap-fit ​​rod is wedge-shaped.

[0010] By adopting the above technical solution, one end of the snap-fit ​​rod is wedge-shaped, which facilitates the fixing of the fixing rod.

[0011] The present invention is further configured such that the tray is made of silicone.

[0012] By adopting the above technical solution and setting the tray material to silicone, the grinding wheel has good cushioning and protection performance.

[0013] The present invention is further configured such that a limiting block is bolted to the surface of the fixing rod, and the limiting block is slidably connected to the inner wall of the mounting base.

[0014] By adopting the above technical solution, a limit block is set to prevent the fixing rod from slipping.

[0015] The present invention is further configured such that an anti-slip sleeve is fixedly sleeved on the surface of the toggle lever.

[0016] By adopting the above technical solution, an anti-slip sleeve is installed to prevent hand slippage and facilitate operation.

[0017] The present invention is further provided that: an anti-slip pad is adhered to the bottom of the base.

[0018] By adopting the above technical solution, anti-slip pads are installed to prevent slippage and improve stability.

[0019] The present invention is further configured such that one end of the fixing rod is arc-shaped.

[0020] By adopting the above technical solution, one end of the fixing rod is made into an arc shape to prevent jamming and improve stability.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. This utility model uses a slot on the tray to match the teeth of the grinding wheel. When changing the grinding wheel, the electric lifting rod moves the tray under the grinding wheel and puts the teeth of the grinding wheel into the slot of the tray. The silicone tray will support and cushion the grinding wheel. On the one hand, it can eliminate the existing manual handling action, and on the other hand, it can avoid the possible collision of the grinding wheel teeth, avoid damage to the grinding wheel teeth, and improve safety.

[0023] 2. This utility model uses a movable lever to disengage the locking rod from the locking hole, and the fixing rod disengages from the fixing hole under the action of the first spring, allowing the tray to be removed, which facilitates tray replacement and improves practicality.
