Detailed Implementation

[0021] The embodiments of this utility model are described in detail below, with reference to Figures 1 to 4 This utility model provides an automatic FPC scraping device, including a frame 100, a drive unit 200, a transmission assembly 300, a scraper 400, and a sample stage 500. The drive unit 200 is mounted on the frame 100 and connected to the scraper 400 via the transmission assembly 300. The sample stage 500 is used to position and place the FPC 700 and is located below the scraper 400. The drive unit 200 can drive the scraper 400 to reciprocate through the transmission assembly 300 to scrape the FPC 700 on the sample stage 500. This scraping device uses the sample stage 500 to position and place the FPC 700, and uses the drive unit 200 and the transmission assembly to drive the scraper 400 to reciprocate to scrape the FPC 700 on the sample stage 500. This simplifies operation, saves labor costs, and improves work efficiency. Moreover, using a mechanical device to replace manual scraping makes it easier to control the scraping speed and force, ensuring the consistency of scraping parameters each time and better verifying the wear resistance of the FPC 700 protective film.

[0022] Furthermore, referring to Figure 1 and Figure 2 The drive unit 200 is a rotary motor, and the transmission assembly 300 includes an eccentric shaft 310, a universal joint 320, a slider 330, and a slide bar 340. The eccentric shaft 310 is fixedly installed at the output end of the drive unit 200. One end of the universal joint 320 is connected to the eccentric shaft 310, and the other end is connected to the slider 330. The slider 330 is slidably connected to the slide bar 340, which is fixedly installed on the frame 100. The scraper 400 is installed below the slider 330. When the rotary motor starts, the eccentric shaft 310 can rotate horizontally, thereby driving the universal joint 320 to reciprocate on the horizontal plane, and finally driving the slider 330 to reciprocate along the slide bar 340, so as to drive the scraper 400 to scrape the FPC700 on the sample stage 500 back and forth.

[0023] Furthermore, a weight holder 600 is vertically slidably connected to the slider 330. The weight holder 600 is used to mount and place the weight 610, and the scraper 400 is fixedly mounted on the lower end of the weight holder 600. By adjusting the weight of the weight 610 placed on the weight holder 600, the downward pressure of the scraper 400 on the FPC700 can be adjusted, thereby quantifying the scraping force and ensuring the consistency of scraping parameters each time. Furthermore, a weight fixing rod 620 is fixedly connected to the top of the weight holder 600. The weight fixing rod 620 is used to connect the weight 610 in series to prevent the weight 610 from falling off when the slider 330 moves back and forth.

[0024] Furthermore, referring to Figure 3This automatic scraping device also includes a counter, which is used to obtain the number of scraping cycles of the scraper 400 to ensure the consistency of scraping parameters each time. The counter can directly identify the number of back-and-forth movements of the scraper 400, or it can identify them indirectly. For example, if the drive unit 200 is a rotary motor, and the counter is electrically connected to the drive unit 200, the counter is used to record the number of rotations of the drive unit 200, thereby obtaining the number of scraping cycles of the scraper 400. To ensure the consistency of scraping parameters each time, the number of rotations of the rotary motor can be preset. The counter uses a counting relay, and the number on the counting relay is preset. For each rotation of the rotary motor, the number on the counter decreases by 1. When the number on the counting relay is 0, the rotary motor stops operating. Furthermore, this automatic scraping device also includes a relay, which is electrically connected to the FPC700 sample lead wire and the scraper 400. When the relay is closed, the drive unit 200 can operate normally. When the scraper 400 scrapes through the protective adhesive of the FPC700 and comes into contact with the FPC700 sample lead wire, the relay is opened, and the drive unit 200 stops operating. Therefore, scraping can be stopped in time at the moment the protective adhesive is scraped through. Furthermore, this automatic scraping device also includes a buzzer, which is electrically connected to the relay. When the relay changes from the closed state to the open state, the buzzer sounds an alarm. At this time, the number of scraping times when NG (not working) can be recorded by the numbers displayed on the counter.

[0025] Furthermore, referring to Figure 1 and Figure 4 The sample stage 500 includes a bottom layer 510, a middle layer 520, a top layer 530, and a clamp 540. The bottom layer 510 is fixedly connected to the frame 100. The middle layer 520 is movably connected to the bottom layer 510 along the X-axis. The top layer 530 is movably connected to the middle layer 520 along the Y-axis. The clamp 540 is mounted on the top layer 530 for positioning and clamping the FPC 700. It adopts a three-layer structure, and the position of the clamp 540 can be adjusted by moving the middle layer 520 and the top layer 530 to facilitate positioning the scraping position. Further, the clamp 540 includes a positioning post 541, a first clamping block 542, and a second clamping block 543. The positioning post 541 is horizontally fixedly mounted on the top layer 530 and protrudes upward from the top layer 530. The positioning post 541 is used to position and support the FPC 700. The first clamping block 542 and the second clamping block 543 can move towards / away from each other to clamp / release the FPC 700. During scraping, the top outer periphery of the positioning post 541 supports the FPC700, and the first clamping block 542 and the second clamping block 543 clamp the FPC700 on both sides. The scraper 400 is located on top of the FPC700 and performs scraping corresponding to the position of the positioning post 541, thus ensuring point contact between the FPC700 and the scraper 400, which is more conducive to scraping verification. Furthermore, the movement of the middle layer 520 and the top layer 530 can be achieved by using a gear and rack mechanism, and the movement of the first clamping block 542 and the second clamping block 543 can be achieved by using an electric gripper mechanism.
