Description

Chip positioning structure

Technical Field

The present application relates to the field of chip processing technology, and in particular to a chip positioning structure.

Background Art

A chip generally refers to an integrated circuit. It uses a certain process to interconnect the transistors, resistors, capacitors, inductors and other components and wiring required in a circuit, and is made on a small piece or several small pieces of semiconductor wafers or dielectric substrates. The chips are then packaged in a tube shell to become a miniature structure with the required circuit functions. All components are structurally integrated, making a major step forward in the direction of miniaturization, low power consumption, intelligence and high reliability of electronic components.

There are many processes in chip processing, such as photolithography and etching, which makes it very important to fix the chip during processing. Once unwanted movement or shaking occurs, the chip may be damaged. Therefore, a positioning structure is used to position and fix the chip. The existing positioning structure is generally a base, and a plurality of pressing tables are slidably arranged on the base. A pressing mechanism (generally a quick pressing clamp) is arranged on the pressing table. When positioning the chip, the chip is placed on a plurality of pressing tables, and a plurality of pressing mechanisms are used to press and fix the four sides or four corners of the chip respectively, so as to achieve the effect of positioning and fixing. Although the pressing or releasing of the pressing mechanism (i.e., the quick pressing clamp) is relatively simple and convenient, in actual use, since multi-point fixation is adopted, multiple pressing mechanisms need to be adjusted when fixing or releasing the fixation, which makes the operation process cumbersome, thereby reducing the processing efficiency. Therefore, the present application proposes a chip positioning structure.

DETAILED DESCRIPTION

In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

As shown in FIG. 1 to FIG. 4 , a chip positioning structure proposed in one embodiment of the present application includes:

Base 1;

A mounting plate 2 is arranged on the base 1, a plurality of supporting blocks 3 are arranged in an array on the outer peripheral side of the mounting plate 2, a support 4 is arranged on the supporting block 3, and a pressure rod 5 is hinged on the support 4;

The movable ring 6 has two guide rods 7 on the base 1, and the ends of the two guide rods 7 are provided with limit plates. The movable ring 6 is slidably sleeved on the two guide rods 7. A spring 8 sleeved on the guide rods 7 is installed between the movable ring 6 and the base 1. A plurality of connecting rods 9 are arranged in an array on the outer peripheral side of the movable ring 6, and the ends of the plurality of connecting rods 9 are provided with adjusting rods 10. The ends of the plurality of adjusting rods 10 are respectively slidably connected with the plurality of pressure rods 5. When the chip is processed and needs to be positioned and fixed, the movable ring 6 is first slid downward so that the movable ring 6 slides downward along the two guide rods 7. The movable ring 6 squeezes the spring 8. When the movable ring 6 moves downward, it drives the plurality of connecting rods 9 to move downward, thereby driving the plurality of adjusting rods 10 to move downward. Since the end of the adjusting rod 10 is slidably connected with the pressure rod 5, and the adjusting rod 10 slides vertically, the adjusting rod 10 moves downward, thereby driving the hinge point of the pressure rod 5 and the support 4 to rotate. , so that the ends of several pressure rods 5 are synchronously away from the supporting blocks 3, and then the chips are placed on several supporting blocks 3. Preferably, the number of supporting blocks 3 is four and they are distributed in a rectangular shape. The four sides of the chip are placed on the four supporting blocks 3 respectively, and then the movable ring 6 is loosened. Under the elastic force of the spring 8, the movable ring 6 slides upward and resets, thereby driving several adjustment rods 10 to move upward and reset, thereby driving several pressure rods 5 to rotate and reset around the hinge point, so that the pressure rod 5 presses the chip placed on the supporting block 3, thereby achieving the role of positioning and fixing, which is convenient for processing. The overall setting of the device can adjust the movement of the movable ring 6 and then use the elastic force of the spring 8 to synchronously adjust the rotation of several pressure rods 5 around the hinge point, so that several pressure rods 5 synchronously press and resist the chip. Compared with the existing pressure clamps that rely on multiple independent quick pressing pliers, the adjustment process is reduced, thereby improving the processing efficiency.

As shown in Figure 4, in some embodiments, one end of the pressure rod 5 is penetrated by a first through groove 11, and the opposite sides of the inner wall of the first through groove 11 are penetrated by second through grooves 12. A support rod 13 is provided at the end of the adjusting rod 10, and the two ends of the support rod 13 slide through the two second through grooves 12 respectively. When the adjusting rod 10 slides, the two ends of the support rod 13 slide along the two second through grooves 12 respectively. Since the adjusting rod 10 slides vertically, when the adjusting rod 10 moves, the support rod 13 slides along the second through groove 12, thereby driving the pressure rod 5 to rotate around the hinge point to achieve the effect of pressing and fixing or releasing the pressing and fixing.

As shown in FIG. 4 , in some embodiments, bearing wheels 14 are provided at both ends of the support rod 13. The two bearing wheels 14 are respectively inserted and rolled in the two second through grooves 12. The bearing wheels 14 are provided to reduce the sliding friction resistance of the support rod 13 along the second through grooves 12, so that the adjustment pressure rod 5 can rotate around the hinge point more smoothly.

As shown in FIG3 , in some embodiments, a plurality of slots 15 are provided in an array on the outer peripheral side of the mounting plate 2, and plug rods 16 are slidably inserted in the plurality of slots 15, and a plurality of supporting blocks 3 are respectively arranged on the plurality of plug rods 16, and the connecting rod 9 adopts a telescopic rod. Preferably, the telescopic rod comprises an outer rod, which is connected to the movable ring 6, and an inner rod is slidably inserted in the outer rod, and the supporting block 3 is arranged on the inner rod, and a support plate 17 is provided on the supporting block 3, and an adjusting rod 10 slides through the support plate 17, and an adjusting member 18 for adjusting the synchronous sliding of the plurality of plug rods 16 is provided on the base 1. By providing the slots 15 on the outer peripheral side of the mounting plate 2, An insertion rod 16 is movably inserted in the slot 15, and the supporting block 3 is set on the insertion rod 16. The adjusting member 18 is used to adjust the synchronous sliding of several insertion rods 16, so that the distance between several supporting blocks 3 can be adjusted at the same time to be suitable for placing chips of different sizes. By setting a support plate 17 on the supporting block 3, the adjusting rod 10 slides through the support plate 17, and the connecting rod 9 adopts a telescopic rod. Therefore, when the supporting block 3 moves, the adjusting rod 10 can be driven to move synchronously, so that when chips of different sizes are pressed and positioned, when the movable ring 6 is adjusted to slide, several pressing rods 5 can still be adjusted synchronously to press and fix the chip.

As shown in FIGS. 2 and 3 , in some embodiments, the adjusting member 18 includes: a rotating rod 1801, which is rotatably connected between the base 1 and the mounting plate 2, a worm wheel 1802 is fixed on the rotating rod 1801, and a worm 1803 meshing with the worm wheel 1802 is rotatably provided on the base 1; a disc 1804, which is fixed on the rotating rod 1801, and a plurality of pull rods 1805 are eccentrically hinged on the disc 1804, and the free ends of the plurality of pull rods 1805 are respectively hinged to the plurality of supporting blocks 3, and the worm 1803 is twisted to adjust the rotation of the rotating rod 1801. 3 rotates, and the engagement of the worm 1803 and the worm wheel 1802 drives the rotating rod 1801 to rotate, thereby driving the disk 1804 to rotate. Since one end of the plurality of pull rods 1805 is eccentrically hinged to the disk 1804, and the other end is respectively hinged to the plurality of supporting blocks 3, when the disk 1804 rotates, the plurality of pull rods 1805 respectively pull or resist the plurality of supporting blocks 3, thereby achieving the effect of synchronously adjusting the movement of the plurality of insertion rods 16, thereby achieving the effect of adjusting the positions of the plurality of supporting blocks 3.

As shown in Figures 1 and 4, in some embodiments, a V-shaped plate 19 is provided on the supporting block 3. Preferably, the angle of the V-shaped plate 19 is 90°. Since most chips are square structures, when fixing the chip, the four corners of the chip are respectively placed in four V-shaped plates 19 to position the chip and avoid horizontal displacement. The pressure of the pressure rod 5 can better position and fix the chip.

As shown in FIG. 4 , in some embodiments, a rubber head 20 is provided at one end of the pressure rod 5 away from the first through groove 11 , and the rubber head 20 is provided to protect the chip and prevent the pressure rod 5 from pressing the surface of the chip hard and causing indentations.

As shown in Figure 2, in some embodiments, a limit rod 21 is rotatably provided on the base 1, and a block 22 is provided at the end of the limit rod 21. When the chip is positioned and fixed, the limit rod 21 is first rotated to move the movable ring 6 down to squeeze the spring 8, and then the limit rod 21 is rotated so that the block 22 overlaps the movable ring 6, thereby setting a limit on the movable ring 6. The movable ring 6 can be temporarily fixed, which is convenient for accurately placing the four corners of the chip in the four V-shaped plates 19. At the same time, when removing and unloading the chip, the movable ring 6 can also be temporarily fixed to facilitate better removal and unloading of the chip.
