Description

Technical Field

[0001] This utility model belongs to the field of antenna component processing, specifically relating to a flexible and automated antenna component end face grinding device. Background Technology

[0002] The antenna assembly consists of a primary mirror and a secondary mirror bonded together. Installed in a millimeter-wave sensor system for a projectile, the antenna assembly receives radiation signals from the target and background, effectively scanning ground-based metallic targets. The primary and secondary mirror substrates are made of polysulfone plastic. According to the manufacturing process, the end faces of the primary and secondary mirrors must be polished before bonding to ensure the antenna assembly's adhesion is strong enough to meet the specified tensile strength requirement of 27 kg ± 2.7 kg.

[0003] Currently, primary and secondary mirrors are polished individually by hand using traditional polishing discs. This process is not only extremely inefficient but also results in uneven polishing, uncontrollable end-face thickness, and poor quality consistency. Furthermore, the diamond abrasive used in the polishing process easily splashes onto the surfaces of the primary and secondary mirrors, creating deep scratches that affect the substrate surface quality and lead to product waste. Applying an electrostatic protective film to the primary and secondary mirrors before polishing can reduce the formation of deep scratches; however, the irregular conical shape of the mirrors and the tension they exhibit, combined with the relatively soft nature of the protective film, makes it prone to lifting at the inner edge, and the application of the film is time-consuming and labor-intensive.

[0024] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0025] This embodiment provides a flexible automated antenna assembly end face grinding device, including: a motor controller, a grinding device 1, a planar conveying device 2, and an antenna fixing device 4;

[0026] The planar conveying device 2 is connected to an antenna fixing device 4 above it, and the antenna fixing device 4 is connected to a grinding device 1 above it.

[0027] The grinding device 1 is connected to the motor controller at the input end of the flat conveyor device 2;

[0028] The antenna fixing device 4 is equipped with the antenna assembly 3 to be ground. The planar conveying device 2 sets the corresponding transmission speed through the motor controller and drives the antenna fixing device 4 into the grinding work area of ​​the grinding device 1 to grind the end face of the antenna assembly 3 to be ground.

[0029] The polishing device 1 is equipped with a sanding belt, which is used to polish the end face of the antenna assembly 3.

[0030] The grinding device 1 is equipped with a lifting column, and the height of the lifting column of the grinding device 1 can be adjusted according to different antenna components 3 to be ground.

[0031] The output of the motor controller is connected to the conveyor motor gearbox device, which is connected to the planar conveyor device 2. The motor controller controls the conveyor motor gearbox device to adjust the conveying speed of the planar conveyor device 2.

[0032] The motor control system features user-friendly operation buttons, enabling one-button control of equipment operation and shutdown. With one-button start, the planar conveyor begins transmission at its designated speed, moving the antenna mounting device into the grinding area to grind the workpiece's end face. After grinding, the workpiece is conveyed to the grinding completion area. The belt abrasive device, equipped with a fine abrasive belt, acts as the transmission mechanism. The workpiece passes through the belt abrasive surface along the planar conveyor, ensuring the flatness and roughness of the antenna assembly's end face. Antenna mounting devices are fabricated according to the antenna assembly size and further differentiated by primary and secondary lenses. The automated grinding equipment includes lifting columns, the height of which can be set according to different products. The antenna mounting device features multi-point antenna assembly mounting devices in each grinding area, accommodating multiple workpieces for simultaneous grinding, improving the grinding efficiency of primary and secondary lenses. The mounting devices employ an anti-scratch and anti-scratch design, ensuring seamless contact with the workpiece, preventing scratches, and reducing scrap rates. A schematic diagram of the automated grinding process is shown below. Figure 1 As shown.

[0033] The automated grinding operation steps for the antenna assembly end face are as follows:

[0034] 1. Loading the workpiece

[0035] 1) Adjust the height of the work area

[0036] The worm gear lift is controlled by a motor via an automated touch screen. The height of the grinding work area is adjusted according to the size of the workpiece. The adjustable height of the grinding work area is ≤10 cm, which ensures that the grinding belt fits in close contact with the workpiece to be ground.

[0037] 2) Insert the workpiece into the embedded auxiliary fixing device.

[0038] The fixing device is made of traceless material. The auxiliary fixing device restricts the workpiece's degree of freedom. The workpiece fits closely to the auxiliary device. The auxiliary fixing device is designed in 4 specifications according to different models of primary and secondary mirror sizes. Each specification has 6 sets of workpiece positions embedded in it to place the workpiece. The grinding work of 6 sets of workpieces can be completed at the same time, while ensuring the consistency and compatibility of grinding height.

[0039] Adjusting the transmission speed of the planar transmission device

[0040] The grinding speed is adjusted by integrating a turbine gearbox with a motor control system, and the speed value is adjusted via a convenient touch screen, ensuring that the grinding roughness is adjustable.

[0041] 2. Automated grinding

[0042] 1) Start the equipment with one button and push the workpiece and auxiliary fixing device into the grinding area.

[0043] (1) By designing convenient operation buttons in the motor control system, the operation and stop of the equipment can be controlled with one button.

[0044] (2) The auxiliary fixing device is firmly attached to the conveyor belt, and the sanding belt grinding device gently grinds the workpiece.

[0045] (3) The workpiece is assembled in the auxiliary device with limited freedom, so it will not deviate from the grinding device during the grinding process, thus ensuring the flatness of the workpiece end face.

[0046] (4) The grinding process selects fine sandpaper of appropriate grit size to achieve uniform, automatic and traceless grinding, which eliminates the need for the protective film application process.

[0047] 2) After automated grinding is completed, the workpiece is ejected by the planar transmission device.

[0048] 3. Remove the workpiece

[0049] The auxiliary device adopts a through-sinking groove design, which allows for quick replacement of the workpiece after grinding. The quick replacement time for a single workpiece is less than 3 seconds, thus completing the grinding process quickly.

[0050] 4. Cleaning

[0051] Achieving a grinding speed of ≥3 pieces / minute for the primary and secondary mirror end faces: Calculated from the completion of the entire grinding process: From the slowest calculation of 2 minutes from the installation of the antenna assembly in the auxiliary fixing device to the completion of grinding and cleaning, at least 6 workpieces can be ground every 2 minutes, which can improve efficiency by 50%.

[0052] 1) Adjustable height of the grinding work area ≤ 10 cm: The grinding work area can be raised and lowered by connecting the worm screw jack and the plane conveyor, thus ensuring that the grinding depth is adjustable.

[0053] 2) Adjustable transmission speed of the flat drive device: The flat drive device is powered by a conveyor motor. By integrating with the turbine gearbox, the grinding speed can be adjusted within a certain range to ensure that the grinding roughness is adjustable.

[0054] 1) Design an auxiliary fixing device for antenna components to ensure flatness and stability during grinding: The workpiece and the auxiliary device are closely fitted, and the workpiece and the auxiliary device have limited freedom of movement after assembly, so that it will not deviate from the grinding device during the grinding process, thus ensuring the flatness of the workpiece end face.

[0055] 2) Optimize the structure of the auxiliary fixing device so that the single-piece quick replacement time is less than 3 seconds: The auxiliary fixing device is designed to embed multiple workpiece positions to place antenna components, and adopts a sunken groove through design to facilitate quick workpiece replacement and complete the grinding process quickly.

[0056] 3) The fixing device adopts a scratch-resistant design to ensure no contact with the workpiece and prevent scratches: the auxiliary fixing device material is selected to ensure that the antenna assembly is stable and does not deform during the grinding process and the base is not damaged.

[0057] 4) Four auxiliary antenna fixing devices are designed according to the size of the primary and secondary antenna mirrors in the product design to ensure consistency and compatibility of grinding height: Multiple specifications of auxiliary fixing devices are designed to meet the requirements of different products with varying primary and secondary mirror heights and sizes. A multi-point embedded design allows for simultaneous grinding of multiple workpieces, ensuring compatibility for grinding all products in production.

[0058] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
