Description

Technical Field

[0002] When producing semiconductor multilayer inductors, the loading process is often completed by sucking the blanks with a vacuum nozzle gripper. Figure 1 As shown in the figure, when picking up a blank, the nozzle must not touch the detection area or mark on the blank. In actual semiconductor multilayer inductor production, commonly used blank sizes are 6 inches, 8 inches, and 10 inches. To prevent the nozzle from touching the detection area and mark during loading, the spacing between the nozzles must be frequently adjusted to accommodate different sizes of blanks.

The suction nozzles are located in the slide groove of the bracket and are fixed by loosening and tightening screws. When the spacing needs to be adjusted, the position of the suction nozzles needs to be adjusted manually one by one. Generally, a mechanical gripper is equipped with four vacuum suction nozzle mechanisms, which suck 4 sheets at a time. Therefore, for sheets of different sizes, the positions of 16 suction nozzles need to be adjusted each time. The adjustment process is extremely inconvenient and inefficient.

[0037] Linear slide rails 200 are respectively fixed on the support arms 101;

[0038] Sliding blocks 300 are respectively slidably fixed on the linear slide rails 200, and the sliding blocks 300 can slide along the linear slide rails 200;

[0039] Nozzles 400 are respectively fixed on the sliding blocks 300, and the nozzles 400 move synchronously with the sliding blocks 300;

[0040] A rotating part 500 is rotatably fixed at the center of the platform part 102 through a hinge shaft, and the rotating part 500 can rotate relative to the support 100;

[0041] A connecting rod 600 is used to connect the rotating part 500 and the slider 300, and the two ends of the connecting rod 600 are respectively hinged to the rotating part 500 and the slider 300, and the rotating part 500 drives the slider 300 through the connecting rod 600.

[0042] The suction nozzle 400 is slidably fixed on the supporting arm 101 of the support 100 through the slider 300 and the linear slide rail 200 to form a sliding pair, the rotating part 500 is connected with the suction nozzle 400 through the connecting rod 600, the connecting rod 600 is respectively hinged to the rotating part 500 and the slider 300 to form two rotating pairs, and the rotating part 500 is rotatably fixed on the platform part 102 to form a rotating pair; wherein the rotating part 500, the connecting rod 600, the suction nozzle 400, the linear slide rail 200 and the slider 300 form a crank slider 300 mechanism, when the rotating part 500 rotates, the slider 300 is driven to slide along the linear slide rail 200 through the connecting rod 600, and the sliders 300 on the four supporting arms 101 are connected with the rotating part 500 through the connecting rod 600, so that the distance between the suction nozzles 400 is adjusted in linkage to adapt to different sizes of tablets, and the position of the suction nozzle 400 is avoided to be adjusted one by one, and the efficiency is improved.

[0043] In the embodiment, the rotating part 500 includes a first rotating rod 501 and a second rotating rod 502, the first rotating rod 501 and the second rotating rod 502 are stacked above and below and are fixed at the center of the platform part 102 through a hinge shaft, and the first rotating rod 501 and the second rotating rod 502 are connected with the sliders 300 with opposite oblique angles through the connecting rod 600. The first rotating rod 501 and the second rotating rod 502 link the sliders 300 with opposite oblique angles respectively, the hinge shaft is located at the center of the first rotating rod 501 and the second rotating rod 502, and the sliders 300 with opposite oblique angles move synchronously, that is, rotating the first rotating rod 501 and the second rotating rod 502 to adjust the distance between the suction nozzles 400.

[0044] In the embodiment, the platform part 102 is provided with a first limiting nut 503 and a second limiting nut 504, and the first limiting nut 503 and the second limiting nut 504 are respectively used to limit the rotation angle of the first rotating rod 501 and the second rotating rod 502.

[0045] In the embodiment, the horizontal height of the first limiting nut 503 and the second limiting nut 504 respectively corresponds to the first rotating rod 501 and the second rotating rod 502. Because the first rotating rod 501 and the second rotating rod 502 are stacked above and below and have different heights, the rotation angle is limited accordingly, so the horizontal height of the first limiting nut 503 and the second limiting nut 504 respectively corresponds to the first rotating rod 501 and the second rotating rod 502.

[0048] In the present embodiment, the positioning pin 700 is adjusted and fixed on the upper and lower sides of the rotating part 500 by two elastic nuts 701. When the positioning pin 700 needs to be lifted upward, the lower locking nut is loosened. After the positioning pin 700 is reinserted into the positioning hole 103, the positioning pin 700 is fixed by the lower locking nut.

When the positioning pin 700 is moved above the designated positioning hole 103, the positioning pin 700 is released, and under the action of the spring force, the positioning pin 700 is reset downward and inserted into the positioning hole 103. In the process of daily use, under the action of the spring force, the positioning pin 700 can be effectively prevented from jumping out of the positioning hole 103 due to vibration.

By arranging an obstacle at the port of the linear slide rail 200, the sliding stroke of the sliding block 300 can be effectively limited to prevent the sliding block 300 from sliding out of the linear slide rail 200.

[0051] In another embodiment, the linear slide rail 200 can be replaced by a linear slide groove, and the slide block 300 is located in the slide groove.

[0052] In another embodiment, the rotating part 500 can be driven by a motor, and the positioning hole 103 and the positioning pin 700 can be replaced by a limit sensor. The rotating part 500 is driven by the motor, thereby automatically adjusting the spacing of the suction nozzle 400 to adapt to different sizes of the sheet material, and the sensor is numbered, corresponding to 6-inch, 8-inch and 10-inch sheet materials respectively. That is, automatic adjustment and automatic positioning are realized, and manual adjustment is completely eliminated, realizing automation.

The rotating part 500, the connecting rod 600, the suction nozzle 400, the linear slide rail 200 and the slide block 300 form a crank slide block 300 mechanism. When the rotating part 500 rotates, the slide block 300 is driven to slide along the linear slide rail 200 through the connecting rod 600. The slide blocks 300 on the four supporting arms 101 are connected with the rotating part 500 through the connecting rod 600, thereby synchronously adjusting the spacing of the suction nozzle 400 to adapt to different sizes of the sheet material. The platform part 102 is provided with a plurality of positioning holes 103, different positioning holes 103 correspond to different commonly used sizes, and the positioning pin 700 cooperates with the positioning hole 103 to realize quick adjustment, positioning and fixing effect.
