[0039] In order to further illustrate the structure of the scraping equipment in the embodiment, the following will be described in detail according to the material preparation, material taking, positioning and placing, conveying, scraping and discharging process.

[0040] Referring to Figures 1 to 4 , about material preparation and material taking part: the adopted feeding assembly includes material box 11, lifting mechanism 12, feeding gripper 13 and translation mechanism 14.

[0041] The sheet ring 15 supporting the substrate 2 is stacked in the magazine 11, the lifting mechanism 12 is arranged at the bottom of the magazine 11 for driving the magazine 11 to move up and down at equal intervals, and the translation mechanism 14 is arranged in parallel with the material scraping platform 1 to move the material feeding gripper 13 through its moving pair and move the material feeding gripper 13 to the magazine 11 to clamp the sheet ring 15 in the magazine 11.

[0042] In addition, the lifting mechanism 12 and the translation mechanism 14 in the embodiment both adopt a servo motor + screw pair structure to realize precise control of transmission.

[0045] In order to simplify the control steps and improve the stability of the sheet ring 15 placed on the material scraping platform 1, the opening side of the magazine 11 is arranged close to and aligned with the top surface of the material scraping platform 1, and the screw pair structure of the translation mechanism 14 passes through the middle part of the material scraping platform 1. For this purpose, a rectangular recess is reserved in the middle part of the material scraping platform 1 to facilitate the installation of the screw pair structure and the movement of the material feeding gripper 13, and to facilitate the taking out of the sheet ring 15 in the magazine 11 by the material feeding gripper 13 and the stable placement of the sheet ring 15 on the top surface of the material scraping platform 1.

[0046] Referring to Figure 1, about positioning and placing part: a light inspection camera 17 is arranged between the material box 11 and the scraping jig 3 and above the scraping platform 1. Specifically, the light inspection camera 17 is fixed on the second gantry 16 and used to detect the position and angle deviation of the substrate 2 relative to the scraping jig 3; meanwhile, the light inspection camera 17 can communicate with the PLC control cabinet, so that when the position and angle deviation of the substrate 2 relative to the scraping jig 3 is found, the PLC control cabinet controls the translation mechanism 14 and the electric turntable 9 at the bottom of the scraping platform 1 to realize the adjustment of the position and angle of the substrate 2, so as to ensure that the scraping knife 4 and the substrate 2 needing to be scraped are "corrected" in position and angle, that is, to ensure that the side edges of the substrate 2 are parallel to the X-axis and Y-axis directions.

[0047] Referring to Figures 4 to 6 , about the conveying and scraping part: the scraping equipment adopted includes the scraping platform 1, the scraping jig 3 and the moving assembly. The scraping platform 1 is used to carry the substrate 2 to be processed, the scraping jig 3 is used to scrape and clean the waste edge material on the substrate 2, and the moving assembly is used to "correct" the substrate 2 and convey the substrate 2 to the corresponding station.

[0048] Specifically, the scraping jig 3 includes the scraping knife 4, the scraping knife lifting structure 6 and the distance measuring unit 5.

[0049] The moving assembly includes the X-axis linear motion assembly 7 and the Y-axis linear motion assembly 8 which are perpendicular to each other. The bottom of the scraping platform 1 is connected with an electric turntable 9 which can drag the scraping platform 1 to rotate around the Z-axis, and the electric turntable 9 can be connected with the moving pair of the X-axis linear motion assembly 7 through a connecting piece, so that the scraping platform 1 can move to the scraping station along the X-axis linear motion assembly 7; the Y-axis linear motion assembly 8 is supported on the first gantry 10 and above the scraping platform 1, and the scraping jig 3 can be connected with the moving pair of the Y-axis linear motion assembly 8 through a connecting piece, so that the scraping knife 4 can be dragged by the Y-axis linear motion assembly 8 to perform the scraping operation of the waste edge material.

[0050] Further, the distance measuring unit 5 preferably adopts a laser range finder which adopts the triangular reflection method for distance measuring (which is a prior art and will not be described here). In this embodiment, since one side of the substrate 2 is tightly attached to the green film 24 by the heat film, the laser range finder fixed on the scraping knife lifting structure 6 can be used to detect the thickness of the substrate 2 and the heat film, and the scraping knife lifting structure 6 can automatically adjust the height of the scraping knife 4 according to the average value of the thickness measured by the laser range finder.

[0051] Specifically, the scraper lifting structure 6 in the embodiment includes a support frame 601, a direct drive guide rail 602, a synchronous belt assembly, and a stepper motor 605. The support frame 601 is fixed on the moving pair of the Y-axis direct drive assembly 8, the knife holder 26 is slidably connected with the support frame 601 through the direct drive guide rail 602, the guide rail of the direct drive guide rail 602 is fixed on the support frame 601, and the slider of the direct drive guide rail 602 is fixedly connected with the knife holder 26. The synchronous belt assembly includes a set of synchronous pulleys 603 and a synchronous belt 604, the synchronous pulleys 603 are rotatably connected to the upper and lower sides of the support frame 601, the synchronous belt 604 is drivingly connected between the synchronous pulleys 603, and the synchronous belt 604 can be fixedly connected with the slider of the direct drive guide rail 602. The stepper motor 605 (supporting electromagnetic brake) drives the synchronous pulleys 603 to rotate, the rotation of the synchronous pulleys 603 drives the synchronous belt 604 to move, thereby automatically adjusting the up and down movement of the knife holder 26.

[0052] With reference to Figure 1 , regarding the blanking part: a material collecting assembly is arranged on the right side of the scraping platform 1 in the X-axis direction. The material collecting assembly includes a direct drive mechanical arm 18, a blanking gripper 19, a rotating part 20, and a storage box 21. The blanking gripper 19 is installed on the rotating part 20, the rotating part 20 is fixed on the direct drive mechanical arm 18, and the storage box 21 is located on one side of the direct drive mechanical arm 18 and is an internal cavity arranged on a workbench 23.

[0053] In the embodiment, by using the displacement ability of the direct drive mechanical arm 18 and the angular displacement ability of the rotating part 20, the blanking gripper 19 can sequentially perform the operations of clamping, retreating, turning over, and moving down on the sheet ring 15 that has completed the waste edge material removal operation of the substrate 2, so as to place the sheet ring 15 in the storage box 21.

[0054] With reference to Figure 5 , the scraping equipment in the embodiment further includes a dust suction pipe 22 and a brush. The dust suction pipe 22 can be fixed on the support frame 601 when in use, so that the pipe opening of the dust suction pipe 22 is close to the scraper 4 and the dust suction pipe 22 can move with the scraper 4. The brush is uniformly distributed at the pipe opening of the dust suction pipe 22. In the embodiment, the other end of the dust suction pipe 22 is connected with a vacuum pump, so that a negative pressure is formed in the dust suction pipe 22 to timely suck the removed waste edge material of the substrate 2 and prevent the waste edge material from flying around. At the same time, the brush can sweep the waste edge material, so as to improve the cleanliness of the surface of the substrate 2, so that the waste edge material removal environment of the substrate 2 is greatly improved, and even the waste edge material flying is basically avoided.

[0055] In summary, the specific scraping process of the photoelectric product scraping equipment in the embodiment is as follows:

[0056] Step 1: Put the array of sheet rings 15 with multiple cut substrates 2 into the magazine 11, and then put the magazine 11 on the top end of the guide rod 25;

[0057] Step 2: The feeding gripper 13 is driven by the translation mechanism 14 to approach the magazine 11. The feeding gripper 13 operates to clamp and take out a sheet ring 15 in the magazine 11, and then places the sheet ring 15 on the scraping platform 1;

[0058] Step 3: The Vision position of each substrate 2 is located by the light detection camera 17. According to the actual state detected by the photographing, the translation mechanism 14 and the electric turntable 9 are controlled to adjust the position and angle of the substrate 2 to ensure that the scraper 4 is "corrected" in position and angle with the substrate 2 to be scraped off the waste edge material;

[0059] Step 4: After the correction is completed, the scraping platform 1 is moved to the scraping position under the action of the X-axis direct drive assembly 7;

[0060] Step 5: The thickness of the substrate 2 is measured by the distance measuring unit 5, and the scraper lifting structure 6 is controlled to automatically adjust the height of the scraper 4 to complete the preparation of the scraper 4;

[0061] Step 6: Then the scraper 4 is dragged by the Y-axis direct drive assembly 8 to scrape off the long waste edge material of the substrate 2, and the long waste edge material is removed by vacuum suction through the dust suction pipe 22. After the scraping platform 1 is rotated by 90°, the scraper 4 is dragged by the Y-axis direct drive assembly 8 to scrape off the short waste edge material of the substrate 2;

[0062] Step 7: Finally, the straight cross mechanical arm 18 cooperates with the rotating part 20 to place the sheet ring 15 that has completed the waste edge material removal of the substrate 2 in the storage box 21.

[0063] Example Two:

[0064] The difference between this embodiment and the above-mentioned embodiment one is that a servo cylinder perpendicular to the Y-axis direct drive assembly 8 is arranged on the Y-axis direct drive assembly 8, so that the scraper 4 has the moving ability in the X-axis and Y-axis directions. Then in the above-mentioned step 6, after the long waste edge material of the substrate 2 is scraped off, the scraping platform 1 does not need to be rotated by 90° by the electric turntable 9 to remove the short waste edge material of the substrate 2. In this embodiment, the servo cylinder is used to displace in the X-axis direction, so that the short waste edge material of the substrate 2 can be removed.

[0065] The above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit the present application; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can be modified, or some technical features can be replaced by equivalent features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present application.
