Description

Technical Field

[0001] The utility model relates to the technical field of gallium arsenide, in particular to a gallium arsenide crystal rod adhesion auxiliary clamp. Background Art

[0002] For GaAs crystal rods with 0F edge, in order to ensure the normal use of GaAs crystal rods, it is necessary to bond the base on the other side of the GaAs crystal rod. During the actual bonding operation, the GaAs crystal rod is placed on the base, and the OF edge of the GaAs crystal rod is adjusted to 45° using a tool to confirm the bonding area of ​​the GaAs crystal rod. After marking the bonding area, the GaAs crystal rod is removed, and mixed glue is applied to the bonding area. The bonding area of ​​the GaAs crystal rod is connected to the concave arc surface of the base, and the GaAs crystal rod is placed on the base again, and the GaAs crystal rod is slightly squeezed to make it fully fit with the base.

[0003] The existing patent 202221194503.3 discloses a gallium arsenide crystal rod bonding auxiliary clamp, which includes a workbench and a clamp body arranged on the workbench. The clamp body is fixedly connected to the workbench through an elastic member. A working area for placing the gallium arsenide crystal rod and the base is formed between the clamp body and the workbench. The inner wall of the clamp body is arranged in an arc shape and matches the shape of the gallium arsenide crystal rod. Support members are provided on the clamp body. The support members are arranged in pairs. The two support members are respectively arranged on both sides of the clamp body. The support members are movably connected to the clamp body and can move up and down along its own axis.

[0004] In the actual implementation of the above patent, although the spring can be used to pull the clamp body, the spring pulling is prone to slight shaking, which affects the accuracy of GaAs bonding. At the same time, rotating the support to press and release GaAs during use requires simultaneous synchronous operation on both sides. If the operation is not performed synchronously at the same time, the position of GaAs may change slightly, which is troublesome to operate and affects the accuracy of bonding again. Therefore, we propose a GaAs crystal rod bonding auxiliary clamp. Utility Model Content

[0005] The utility model aims to provide a gallium arsenide crystal rod adhesion auxiliary clamp, which solves the problems raised in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gallium arsenide crystal rod adhesion auxiliary fixture, comprising a base, and limit plates are installed on both sides of the top of the base;

[0007] A support plate is fixed to one side of the top of the base, and a lifting plate is connected to one side wall of the support plate. Limiting grooves are provided on both sides of one side wall of the support plate, and an adaptive limiting slider is inserted into the inner cavity of the limiting groove.

[0009] As a preferred implementation of the utility model, a limiting strip is fixed to one side of the bottom of the inclined plate.

[0010] By adopting the above technical solution and setting the limiting strip, the GaAs crystal rod can be limited when it is adsorbed, so as to ensure the accurate position of the GaAs crystal rod, and further ensure the high accuracy when the GaAs crystal rod is lowered and bonded.

[0011] As a preferred embodiment of the utility model, a strip groove is opened on the top of the base, a dual-axis motor is fixed in the middle of the inner cavity of the strip groove, screw rods are fixed at both ends of the dual-axis motor, the outer end of the screw rod is rotatably connected to the inner wall of the strip groove, the outer wall of the screw rod is covered with an adaptive screw rod slider, and the top of the screw rod slider is fixedly connected to the corresponding limit plate.

[0012] By adopting the above technical solution, the dual-axis motor can drive the lead screw to rotate, thereby driving the lead screw sliders on both sides to move, thereby driving the limit plates on both sides to move synchronously closer to or farther away from each other, so that the base can be clamped and positioned, and the base can be ensured to be centered compared to the limit plates on both sides when clamped, thereby achieving rapid positioning while ensuring the accuracy of the alignment of the base and the gallium arsenide crystal rod, thereby further improving the accuracy of bonding.

[0013] As a preferred implementation of the utility model, an adaptive rubber strip is fixedly glued to the inner side wall of the limiting plate.

[0014] By adopting the above technical solution and setting the rubber strip, the limiting plate can avoid abrasion of the base when clamping and limiting the base, while ensuring a high degree of clamping fit.

[0015] As a preferred embodiment of the present invention, the inclination angle of the inclined plate is 45°.

[0016] By adopting the above technical solution, it is ensured that the positions of the gallium arsenide crystal rod and the base correspond accurately after the inclined plate and the gallium arsenide crystal rod are flatly attached and adsorbed.

[0017] As a preferred embodiment of the utility model, rubber blocks are embedded at the four corners of the bottom of the base.

[0018] By adopting the above technical solution and the provision of the rubber block, the overall stability of the device is high during use, and sliding is avoided.

[0019] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0020] The gallium arsenide crystal rod bonding auxiliary fixture of the technical solution of the present application places the base between two limiting plates for limiting, and then uses the bottom of the inclined plate to fit on the plane of the gallium arsenide crystal rod, so that the negative pressure hole negatively absorbs the gallium arsenide crystal rod, and then the electric push rod drives the lifting plate to descend, so that the gallium arsenide crystal rod can be accurately pressed on the base for bonding, which improves the convenience of operation, and the limiting strip can be used to limit the gallium arsenide crystal rod during adsorption, thereby improving the accuracy of gallium arsenide crystal rod bonding;

Limiting grooves are provided on both sides of one side wall of the support plate 2, and an adaptive limiting slider 21 is inserted into the inner cavity of the limiting groove. An electric push rod 22 is fixed to the top of the limiting slider 21, and the outer end of the electric push rod 22 is fixedly connected to the top of the inner cavity of the limiting groove, and the outer wall of the limiting slider 21 is fixedly connected to the end face of the lifting plate 3.

The outer end of the negative pressure pump 32 is connected to the cavity of the inclined plate 31, and a plurality of evenly distributed negative pressure holes 33 are provided at the bottom of the inclined plate 31.

[0032] In actual use, firstly, the flat surface of the gallium arsenide crystal rod is attached to the bottom of the inclined plate 31, and then the negative pressure pump 32 is started to generate negative pressure on the inclined plate 31, so that the negative pressure hole 33 is used to generate negative pressure, so that the gallium arsenide crystal rod is firmly adsorbed, and then the base is placed between the limit plates 11 on both sides for limiting, and then the electric push rod 22 drives the limit slider 21 to descend, so that the lifting plate 3 descends, so that the gallium arsenide crystal rod can be driven down to the surface of the base for bonding, and the operation is convenient and quick.

[0033] Furthermore, rubber blocks are embedded at the four corners of the bottom of the base 1. The provision of the rubber blocks ensures that the device as a whole has high stability during use and avoids sliding.

[0034] Furthermore, an adaptive rubber strip is fixedly glued to the inner wall of the limiting plate 11. The provision of the rubber strip can prevent the base from being worn when the limiting plate 11 clamps and limits the base, while ensuring a high degree of clamping fit.

[0035] It is worth mentioning that the tilting angle of the tilting plate 31 is 45°, so as to ensure that the positions of the GaAs crystal rod and the base correspond accurately after the tilting plate 31 and the GaAs crystal rod are flatly attached and adsorbed.

[0036] like Figure 1 and 2As shown; a limit strip 34 is fixed to one side of the bottom of the inclined plate 31. The setting of the limit strip 34 enables the GaAs crystal rod to be limited when it is adsorbed, thereby ensuring the accurate position of the GaAs crystal rod, and further ensuring high accuracy when the GaAs crystal rod is lowered and bonded.

[0038] The dual-axis motor 12 can drive the screw 13 to rotate, thereby driving the screw sliders 14 on both sides to move, thereby driving the limit plates 11 on both sides to move closer or farther away from each other synchronously, so that the base can be clamped and positioned, and the base can be ensured to be centered compared to the limit plates 11 on both sides when clamped, so as to achieve rapid positioning while ensuring the accuracy of the alignment of the base and the gallium arsenide crystal rod, thereby further improving the accuracy of bonding.

[0039] The implementation principle of the gallium arsenide crystal rod adhesion auxiliary clamp of the present application is as follows: in actual use, the gallium arsenide crystal rod is first placed between the two limit plates 11, and then the dual-axis motor 12 can drive the screw 13 to rotate, thereby driving the screw sliders 14 on both sides to move, so as to drive the limit plates 11 on both sides to approach each other synchronously, so as to clamp and position the base, and ensure that the base is centered relative to the limit plates 11 on both sides during clamping, and then the plane of the gallium arsenide crystal rod is attached to the bottom of the inclined plate 31, and then the negative pressure pump 32 is started to make the inclined plate 31 generate negative pressure, so as to generate negative pressure by using the negative pressure hole 33, so as to firmly adsorb the gallium arsenide crystal rod, and when the gallium arsenide crystal rod is adsorbed, the gallium arsenide crystal rod can be limited to ensure the accurate position of the gallium arsenide crystal rod, and then the electric push rod 22 drives the limit slider 21 to descend, so that the lifting plate 3 descends, so that the gallium arsenide crystal rod can be driven down to the surface of the base for bonding, the operation is convenient and quick, and the bonding accuracy is high.
