Description
Technical Field
[0001] The utility model relates to the field of polishing devices, in particular to a polishing device for the insulating layer of the welding foot of an LCM backlight fixed iron frame. Background Art
[0002] Liquid Crystal Modules (LCMs) are essential display components in modern electronic devices. They control the arrangement of liquid crystal molecules to adjust light transmission, thereby displaying images. The backlight mounting frame plays a crucial role in the LCM's structure. It provides solid support for the backlight source and ensures the stability of the electrical connection. However, to ensure the electrical safety of the LCM backlight mounting frame, its surface is typically covered with an insulating layer to prevent electrical short circuits. However, the presence of this insulating layer also requires polishing on specific solder pins so that the grounding wire can directly contact the metal part of the frame for effective grounding. This step is crucial to ensuring the reliability and safety of the LCM.
[0003] In existing technology, the insulation layer of the soldered pins of the LCM backlight mounting iron frame is typically polished using a manual handheld polishing device. The operator needs to manually control the polishing tool to precisely polish the insulation layer of the soldered pins to ensure the connection of the ground wire. However, this manual operation method has many limitations. First, it is difficult to ensure consistency and accuracy when polishing with a handheld grinder, and the polishing quality is difficult to guarantee. Second, manual polishing is inefficient and cannot meet the needs of large-scale production. In addition, prolonged manual operation may cause operator fatigue, further affecting the quality and efficiency of polishing. Utility Model Content
[0004] In response to the shortcomings of the existing technology, the purpose of the present utility model is to provide an insulation layer grinding device for the welding feet of the LCM backlight fixed iron frame, comprising a base plate, a slide fixedly connected to the front side of the top of the base plate, a skateboard slidably connected to the top of the slide, the skateboard slides left and right on the slide, a support plate slidably connected to the top of the skateboard, the support plate slides back and forth on the skateboard, a placement groove is opened on the left side of the top of the support plate for placing the LCM backlight fixed iron frame, a column is fixedly connected to the rear side of the top of the base plate, and a grinder is fixedly connected to the front side of the upper part of the column for grinding the insulation layer on the welding feet of the LCM backlight fixed iron frame.
[0005] Furthermore, a first limit column is fixedly connected to the left end of the slide, and a first adjusting screw is threaded on the first limit column. When the slide slides to the leftmost end, it abuts against the right end of the first adjusting screw; a second limit column is fixedly connected to the right side of the front end of the slide, and the second limit column is threaded with the second adjusting screw. A limit block is fixedly connected to the middle part of the front end of the slide, and when the slide slides to the rightmost end, the limit block abuts against the left end of the second adjusting screw.
[0006] Furthermore, two guide rods are fixedly connected to the right end of the slide, and holes corresponding to the two guide rods are opened at the right end of the slide. The two guide rods are slidably connected to the holes opened at the right end of the slide.
[0007] Furthermore, a first mounting post is fixedly connected to the top of the skateboard, and a second mounting post is fixedly connected to the left side of the bottom end of the support plate. The positions of the first mounting post and the second mounting post correspond front to back, and a spring is clamped between the first mounting post and the second mounting post.
[0008] Furthermore, a positioning block is fixedly connected to the rear side of the top end of the support plate, and the positioning block corresponds to the opening of the LCM backlight fixing iron frame.
[0009] Compared with the prior art, the beneficial effects of the present invention are:
[0010] 1. Improved work efficiency and grinding quality: By securing the grinder, the insulating layer of the welded legs of the LCM backlight mounting frame can be polished by simply sliding the slide and support plate, eliminating the need for manual handheld grinding and improving work efficiency. By adjusting the second adjustment screw, when the slide is slid to the far right, the welded legs of the LCM backlight mounting frame precisely contact the grinding head of the grinder, ensuring consistent grinding thickness each time and improving grinding quality.
[0011] 2. Ensures consistent grinding direction and position: By designing a positioning block on the rear side of the top of the pallet, this device ensures that each LCM backlight fixing iron frame is placed with the open end facing backward, ensuring that each grinding is targeted at the same welding foot. This design ensures consistent and standardized grinding. This not only improves production efficiency but also helps reduce damage or rework caused by positioning errors.

DETAILED DESCRIPTION
[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the technical solutions in the specific implementation methods of the present invention are clearly and completely described below to further illustrate the present invention. Obviously, the specific implementation methods described are only part of the implementation methods of the present invention, rather than all styles.
[0020] The structure of the LCM backlight fixing iron frame 80 is shown in the figure below. Figure 5 As shown, the outer surface of the LCM backlight fixing iron frame 80 is covered with an insulating layer. In order to ground, the outer side of the welding foot 801 shown in the figure needs to be polished to remove the insulating layer. As can be seen from the figure, one side of the LCM backlight fixing iron frame 80 has an opening 802.
[0021] Example 1: Figures 1 to 4 As shown, the insulating layer grinding device for the welding foot of the LCM backlight fixed iron frame includes a base plate 10, a slide 20 is fixedly connected to the front side of the top of the base plate 10, a slide 30 is slidably connected to the top of the slide 20, two guide rods 40 are fixedly connected to the right end of the slide 30, and holes corresponding to the two guide rods 40 are opened at the right end of the slide 20. The two guide rods 40 are slidably connected to the holes opened at the right end of the slide 20, and the slide 30 can slide left and right on the slide 20 through the guiding effect of the two guide rods 40. The top of the slide 30 is slidably connected to a support plate 50, and the support plate 50 slides back and forth on the slide 30. A placement groove 501 is opened on the left side of the top of the support plate 50 for placing the LCM backlight fixed iron frame 80, and a column 101 is fixedly connected to the rear side of the top of the base plate 10, and a grinder 60 is fixedly connected to the front side of the upper part of the column 101 for grinding the insulating layer on the welding foot 801 of the LCM backlight fixed iron frame 80.
[0022] A first limiting post 201 is fixedly connected to the left end of the slide 20. A first adjustment screw 202 is threadedly connected to the first limiting post 201. When the slide 30 slides to its leftmost end, it abuts the right end of the first adjustment screw 202. A second limiting post 203 is fixedly connected to the right side of the front end of the slide 20. A second adjustment screw 204 is threadedly connected to the second limiting post 203. A limiting block 301 is fixedly connected to the middle of the front end of the slide 30. When the slide 30 slides to its rightmost end, the limiting block 301 abuts the left end of the second adjustment screw 204. By adjusting the second adjustment screw 204, the welded leg 801 of the LCM backlight fixed iron frame 80 can be precisely contacted with the grinding head of the grinder 60 when the slide 30 slides to its rightmost end.
[0023] When using this grinding device, first slide the slide plate 30 to the extreme left end and abut against the right end of the first adjusting screw 202, then place the LCM backlight fixing iron frame 80 on the placement groove 501, and then push the slide plate 30 to the extreme right end, and then slide the support plate 50 back and forth to use the grinder 60 to grind the insulation layer on the welding foot 801 of the LCM backlight fixing iron frame 80. During this process, the grinder 60 is in the open state throughout the process.
[0024] Example 2: This example is similar to Example 1. In addition to Example 1, a first mounting post 302 is further fixedly connected to the top of the slide plate 30, and a second mounting post 502 is fixedly connected to the left side of the bottom end of the support plate 50. The first mounting post 302 and the second mounting post 502 are positioned in a front-to-back relationship, and a spring 70 is clamped between the first mounting post 302 and the second mounting post 502. By providing the spring 70, the spring 70 is stretched when the support plate 50 is slid backward, and the elastic force of the spring 70 automatically returns the support plate 50 to its original position when the support plate 50 is released. This avoids the need to manually slide the support plate 50 back and forth, thereby improving grinding efficiency.
[0025] like Figure 5 As shown, an opening 802 is provided in the middle of the rear end of the LCM backlight fixed iron frame 80, and a positioning block 503 is fixedly connected to the rear side of the top end of the support plate 50. The positioning block 503 is triangular, and its front end can be placed in the middle opening 802 of the rear end of the LCM backlight fixed iron frame 80. By setting the positioning block 503, it can be ensured that one end of the opening 802 of each LCM backlight fixed iron frame 80 faces backward, ensuring that the welding foot 801 of each LCM backlight fixed iron frame 80 is polished at the right rear.
