Description

Technical Field

[0001] This utility model relates to the field of dip coating machine technology, and in particular to a fixing device for a VCD robotic arm that detects the reflector plate in the color film coating section of a display panel. Background Technology

[0002] In the color filter coating process of panel manufacturing, after the photoresist is evenly coated on the substrate surface, it needs to be dried. The main purpose of VCD (low-pressure photoresist drying) is to remove volatile components such as solvents from the photoresist, so that the photoresist can better adhere to the substrate and form a stable photoresist film layer that meets the process requirements, thus preparing for subsequent exposure, development and other process steps.

[0003] In the VCD manufacturing process, specifically during the color filter coating stage at a panel factory, robotic arms need to precisely perform various actions, such as grasping and placing substrates. To enable precise substrate handling, a detection reflector is typically installed on the VCD equipment. This reflector works in conjunction with a photoelectric sensor to accurately determine the robotic arm's position. When light emitted from the robotic arm's photoelectric sensor illuminates the reflector, the signal from the reflected light is used to determine whether the robotic arm has reached a specific position, such as whether it has accurately placed the substrate into the designated location within the VCD equipment or precisely removed the substrate from the VCD equipment.

[0004] like Figure 1 As shown, the existing detection reflector 3 is installed on the edge of the VCD device frame 4, and the top surface of the detection reflector protrudes from the VCD device frame. To ensure the normal operation of the VCD device, personnel need to clean it regularly, such as removing residual solvents, dust, and other impurities from inside the device. Simultaneously, key components of the equipment (such as vacuum pumps and valves) must be inspected and maintained to ensure continuous and stable operation. However, the detection reflector protruding from the VCD device frame is prone to deformation under pressure during maintenance, which can cause the receiver to fail to receive signals, leading to the coating machine malfunctioning. Furthermore, prolonged storage of coated products can result in product defects and scrap, impacting factory costs, product yield, and uptime. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a fixing device for the detection reflector of the VCD robotic arm in the color film coating section of the display panel, which can prevent the detection reflector from being deformed by pressure during operation.

[0006] This utility model is implemented as follows:

[0007] This utility model provides a fixing device for the detection reflector of a VCD robotic arm in the color film coating section of a display panel. It includes a fixing seat installed on the outer edge of the VCD device. The top of the fixing seat has a mounting groove corresponding to the detection reflector. The depth of the mounting groove is greater than the height of the detection reflector, so that the detection reflector is hidden inside the mounting groove.

[0008] Furthermore, the detection reflector has long slot countersunk holes at both ends, and the length of the long slot countersunk holes extends into the width of the fixing base.

[0009] Furthermore, the length of the mounting groove is greater than the length of the detection reflector, and the side wall of the fixing seat is provided with an elongated hole that communicates with the mounting groove. The length of the elongated hole matches the length of the mounting groove. The fixing bolt passes through the elongated hole and connects with the detection reflector to fix the detection reflector in the mounting groove.

[0010] Furthermore, the mounting base is made of 6061 aluminum.

[0011] The advantages of this utility model are: by concealing the detection reflector inside the installation groove, it can prevent the detection reflector from being deformed by pressure during operation, avoid abnormal detection reflector, avoid the coating machine from shutting down, resulting in defective or scrapped products, and improve the uptime of the equipment.

[0018] Please see Figures 2 to 3This utility model provides a fixing device for the detection reflector plate of a VCD robotic arm in the color film coating section of a display panel. It includes a fixing base 1 installed on the outer edge of the VCD device. The top of the fixing base 1 has a mounting groove 11 corresponding to the detection reflector plate 2. The depth of the mounting groove 11 is greater than the height of the detection reflector plate 2, so that the detection reflector plate 2 is concealed within the mounting groove 11. Because the detection reflector plate 2 is concealed within the mounting groove 11, it is less likely to be compressed during operation. Therefore, it can prevent the detection reflector plate 2 from being deformed by pressure during operation, avoiding abnormalities in the detection reflector plate 2 that could cause the coating machine to shut down, resulting in defective or scrapped products, and improving the equipment's uptime.

[0019] Specifically, the detection reflector 2 has elongated countersunk holes 12 at both ends, the length of which extends into the width of the mounting base 1. The mounting position of the mounting base 1 can be adjusted via the elongated countersunk holes 12 to allow the detection reflector 2 to be installed in the desired position.

[0020] Specifically, the length of the mounting groove 11 is greater than the length of the detection reflector 2. The side wall of the fixing base 1 is provided with an elongated hole 13 communicating with the mounting groove 11. The length of the elongated hole 13 matches the length of the mounting groove 11. A fixing bolt passes through the elongated hole 13 and connects to the detection reflector 2 to fix the detection reflector 2 within the mounting groove 11. The elongated hole 13 allows adjustment of the installation position of the detection reflector 2 to ensure it is installed in the desired location. The countersunk hole 12 and the elongated hole 13 are used to adjust the position of the detection reflector 2 in two directions (X-axis and Y-axis) to ensure it is installed in the desired location.

[0021] Specifically, the mounting base 1 is made of 6061 aluminum. Furthermore, to improve the corrosion resistance of the mounting base 1, it can be anodized to its original color.
