Abstract
Description
Technical Field
[0001] The present application relates to the field of chip processing, and in particular to a loading and unloading cover opening mechanism. Background Art
[0002] There is a detection step in the chip processing process. Clamping blocks for positioning the chip are installed on both sides of the test seat. When the chip needs to be placed, it is necessary to press the clamping structure first to open the clamping structure, and then place the chip on the test seat, and finally release the clamping structure. At this time, the clamping structure positions the chip, which is convenient for the test seat to detect the chip. In order to facilitate the placement of chips, the existing chip transmission structure will be installed with a pressing structure directly below the manipulator. The pressing structure plays the role of pressing the clamping block. A hole for the manipulator to place the chip is opened in the center of the pressing structure. The manipulator passes through the hole to pick up the chip. After the material thickness is determined, the chip is moved to the top of the test seat, and the pressing structure presses the clamping structure. The manipulator moves down to place the chip on the test seat.
[0003] However, during the actual operation of the equipment, the pressing structure is located directly below the robot arm. After the robot arm moves down to pick up the material, the chip position is not positioned, causing the pressing structure to interfere with the robot arm's material picking, causing the chip on the robot arm to fall off the robot arm, affecting the chip processing efficiency.

[0034] The following is combined with Figure 1-Figure 8 This application is described in further detail.
[0035] The present application embodiment discloses a loading and unloading cover opening mechanism. Figure 1 and Figure 2 , including a mounting frame 1, a plurality of adsorbing members 2 for adsorbing chips, and a pressing member 3 for pressing and opening the clamping structure on the detection seat. In the embodiment of the present application, a plurality of adsorbing members 2 are sequentially arranged along the length direction of the mounting frame 1 and are located at the lower end of the mounting frame 1, so that the adsorbing members 2 can adsorb chips. The pressing member 3 is installed on the mounting frame 1 and is located below the adsorbing members 2. The mounting frame 1 is provided with a pushing member 4 for driving the pressing member 3 to move along the width direction of the mounting frame 1.
[0036] Reference Figure 3 and Figure 4In order to extend the stroke of the adsorption member 2 moving up and down, a connecting plate 5 is installed on the side of the mounting frame 1 facing the adsorption member 2. A driving member 6 for driving the connecting plate 5 to move up and down is fixedly installed on the mounting frame 1. The driving member 6 includes a servo motor installed on the mounting frame 1 and a ball screw arranged at the piston end of the servo motor. The connecting plate 5 is connected to the nut of the ball screw, so that the servo motor drives the connecting plate 5 to move up and down. The driving member 6 can also be a cylinder. The main purpose of the driving member 6 is to drive the connecting plate 5 to move up and down. Several adsorption members 2 are arranged in sequence along the length direction of the connecting plate 5. The adsorption member 2 includes a mobile cylinder 22 installed on the connecting plate 5 and a suction nozzle 21 arranged at the piston end of the mobile cylinder 22. The mobile cylinder 22 is used to drive the suction nozzle 21 to move up and down to pick up materials. In order to facilitate the installation of the adsorption component 2 and to facilitate the adjustment of the spacing between several adsorption components 2, a slide rail 7 is fixedly installed along the length direction on the side of the connecting plate 5 facing the adsorption component 2. Multiple groups of slide rails 7 are arranged. Several sliders 8 are fixedly installed on the side of the adsorption component 2 close to the slide rail 7. The slider 8 is located on the side of the moving cylinder 22 facing the slide rail 7.
[0037] Reference Figure 4 and Figure 5 When the suction nozzle 21 adsorbs the chip to be detected, the pushing member 4 drives the pressing member 3 to move toward the mounting frame 1 to avoid the suction nozzle 21 and facilitate the suction nozzle 21 to adsorb the chip. The pushing member 4 includes a pushing cylinder 41 fixedly installed on the mounting frame 1 and a connecting block 42 fixedly installed on the piston end of the pushing cylinder 41 and connected to the pressing member 3. The piston end of the pushing cylinder 41 is arranged along the width direction of the mounting frame 1, so that the pushing cylinder 41 drives the pressing member 3 to reciprocate along the width direction of the mounting frame 1. In order to improve the stability of the movement of the pressing member 3, the mounting frame 1 is fixedly installed with a guide rail 14 along the width direction, and the pressing member 3 is fixedly installed with a guide block 15 located on the guide rail 14.
[0038] Reference Figure 5 and Figure 6 The pressing member 3 includes a mounting plate 31 and a plurality of pressing seats 32 mounted on the mounting plate 31. The mounting plate 31 is arranged on the bottom surface of the guide block 15. The mounting plate 31 is driven to retract to avoid the suction nozzle 21 by pushing the cylinder 41. The plurality of pressing seats 32 are arranged in sequence along the length direction of the mounting plate 31 corresponding to the plurality of suction nozzles 21. One pressing seat 32 corresponds to one suction nozzle 21. The top surface of the mounting plate 31 is provided with a plurality of mounting holes 9 for mounting the pressing seats 32 along the length direction, so as to improve the stability of the pressing seats 32 on the mounting plate 31.
[0039] Reference Figure 7 and Figure 8The pressing seat 32 includes a positioning frame 321 installed on the mounting plate 31 and located in the mounting hole 9, a limiting frame 322 arranged below the positioning frame 321 and extending downward, and a pressing frame 323 arranged in the limiting frame 322. Space for the chip to pass through is formed in the positioning frame 321, the limiting frame 322 and the pressing frame 323. The inner diameter of the limiting frame 322 is larger than the inner diameter of the pressing frame 323. The limiting frame 322 is provided with a limiting groove 10 along the height direction. The pressing frame 323 is fixed with a limiting block 11 located in the limiting groove 10. The limiting frame 322 is fixed with an elastic member 12 located in the limiting groove 10. One end of the elastic member 12 is connected to the limiting frame 322, and the other end of the elastic member 12 is connected to the limiting block 11. The elastic member 12 uses a spring in the embodiment of the present application. The bottom surface of the pressing frame 323 is provided with an avoidance groove 13, which is used to avoid the clamping structure pressed open by the pressing frame 323 and provide a chip placement path. The inner wall of the pressing frame 323 is arranged from top to bottom as a reduction portion and a flat portion, and the reduction portion gradually reduces the distance between the two inner side walls downward, which is used to guide the chip to enter the detection seat accurately; the flat portion gradually increases the distance between the two inner side walls, and the maximum distance between the flat portion and the two inner side walls is smaller than the maximum distance between the reduction portion and the two inner side walls.
[0040] The implementation principle of a loading and unloading cover opening mechanism in the embodiment of the present application is as follows: when the loading and unloading cover opening mechanism of the present application is installed in the device, a linear motor or other driving structure such as a cylinder can be used to drive the cover opening mechanism to move horizontally or vertically. The linear motor drives the mounting frame 1 to move to the top of the chip placement tray to be detected, and then drives the cylinder 41 to start and drive the pressing part 3 to move toward the mounting frame 1 away from the adsorption part 2, and the moving cylinder 22 drives the suction nozzle 21 to move down to adsorb the chip. After the chip is adsorbed, the moving cylinder 22 drives the suction nozzle 21 to move up, and the suction nozzle 21 moves up to drive the chip to move up to the top of the mounting plate 31.
[0041] After the push cylinder 41 pushes the mounting plate 31 to move directly below the chip; the linear motor drives the mounting frame 1 to move directly above the detection seat, and another set of cylinders or linear motors are used to drive the mounting frame 1 to move downward as a whole, and the pressing frame 323 presses the clamping structure on the detection seat. After the clamping structure is opened, the suction nozzle 21 moves downward to drive the chip into the pressing frame 323, and then the suction nozzle 21 passes through the pressing frame 323 and places the chip on the detection seat for detection.
[0042] The pressing frame 323 moves upward, and the clamping structure positions the chip, improving the stability of the chip on the test seat. After the chip test is completed, the pressing frame 323 continues to press the clamping structure, and the suction nozzle 21 passes through the pressing frame 323 to absorb the chip. Since the chip is placed in the test seat through the pressing frame 323 and the placement position is calibrated, the chip will not be disturbed by the pressing frame 323 when the suction nozzle 21 absorbs the chip, and the chip can be accurately taken out of the pressing frame 323. This application effectively avoids the phenomenon of the chip falling when it is taken and placed, and improves the stability of the chip on the test seat.
[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
