[0022] Example 1

[0023] Embodiment 1 of the utility model is a fixing device for processing power amplifier chips, comprising a base plate 1, a clamping assembly 3 for clamping the power amplifier chip is arranged above the base plate 1, a sliding assembly 2 is arranged between the clamping assembly 3 and the base plate 1, and the sliding assembly 2 drives the clamping assembly 3 to move.

[0024] Reference Figure 1 to Figure 3 The sliding component 2 is mainly used for moving the clamping component 3, so as to facilitate the clamping component 3 to move closer to or farther from the middle of the bottom plate 1 to adapt to the clamping of power amplifier chips of different lengths; the internal structure of the clamping component 3 can be adaptively adjusted according to the width of the power amplifier chip to better clamp the power amplifier chip and facilitate taking it, so that the device has reusability.

[0025] In some preferred embodiments, the clamping assembly 3 includes two movable plates 30 , and clamping accommodating frames 31 are respectively provided on opposite sides of the two movable plates 30 , and the clamping accommodating frames 31 fix the power amplifier chip.

[0026] Specifically, refer to Figure 1The two moving plates 30 are symmetrically located above the bottom plate 1, and the clamping and containing frames 31 are located on the sides of the moving plates 30. The two clamping and containing frames 31 are symmetrical to each other. At the same time, the clamping and containing frames 31 are hollow inside, and the side away from the moving plates 30 is open, which is convenient for clamping the power amplifier chip, providing adjustment space to adapt to power amplifier chips of different specifications, and improving the utilization rate of the device. The number of clamping and containing frames 31 is not limited here, and can adapt to the processing of a large number of power amplifier chips after being fixed.

[0027] In some preferred embodiments, a clamping plate 32 and a spring 33 are respectively disposed at the two inner ends of the clamping accommodating frame 31 , and two ends of the spring 33 are respectively fixedly connected to the clamping plate 32 and the inner end of the clamping accommodating frame 31 .

[0028] Specifically, the spring 33 connects the clamping plate 32 and the inner end of the clamping frame 31, providing conditions for the clamping plate 32 to adjust the clamping width. At the same time, in the process of clamping the power amplifier chip, one of the clamping plates 32 is first compressed in the direction of the spring 33, and then the power amplifier chip is placed in the clamping space. The elastic action of the spring 33 enables the clamping plates 32 at both ends of the power amplifier chip to be firmly clamped to avoid detachment during the processing.

[0029] In some preferred embodiments, the inner wall of the clamping frame 31 close to the movable plate 30 is provided with a sliding groove 34, and one end of the clamping plate 32 is located in the sliding groove 34. A rubber pad 35 is also included, and the rubber pad 35 is located on the side of the clamping plate 32 away from the spring 33 and the inner wall of the clamping frame 31 close to the movable plate 30.

[0030] Specifically, Figure 2 As shown, one end of the clamping plate 32 is located in the slide groove, which is for the movement of the clamping plate 32 in the clamping frame 31 on the one hand, and for limiting the clamping plate 32 on the other hand, to prevent the clamping plate 32 fixedly connected to the spring 33 from deflecting during the clamping process, so as to maximize the clamping effect on the power amplifier chip. The rubber pad 35 is mainly located on the side and inner bottom surface of the clamping frame 31 provided with the slide groove 34, and the two side surfaces opposite to the clamping plate 32.

[0031] In some preferred embodiments, one side of the movable plate 30 is disposed on a stabilizing plate 36 , one side of the stabilizing plate 36 is on the same side as the clamping and accommodating frame 31 , and a rubber pad 35 is disposed on the surface of the stabilizing plate 36 .

[0032] Specifically, Figure 3As shown, the stabilizing plate 36 is mainly used to support the bottom surface of the power amplifier chip. A layer of rubber pad 35 matching the stabilizing plate 36 is arranged on the surface of the stabilizing plate 36, so that the surface of the rubber pad 35 is flush with the rubber pad 35 on the bottom surface of the clamping accommodating frame 31, effectively protecting the power amplifier chip from damage during the clamping process. The size of the stabilizing plate 36 is set according to actual conditions to ensure that it does not affect the support of the bottom surface of power amplifier chips of various specifications.

[0033] Example 2

[0034] This embodiment 2 is implemented on the basis of embodiment 1, and the sliding assembly 2 includes a driving motor and a screw rod 21 with a sliding block 22, and two fixed rods 20 are symmetrically arranged in the base plate 1. One end of the screw rod 21 is located in the fixed rod 20, and the surface of the sliding block 22 is movably connected to two connecting rods 23. The end of the connecting rod 23 away from the sliding block 22 is connected to the bottom of the movable plate 30.

[0035] Specifically, the sliding assembly 2 turns on the driving motor, which drives the screw 21 to rotate, and the sliding block 22 sleeved on the outer periphery of the screw 21 moves. The connecting rod 23 on the top surface of the sliding block 22 will drive the two moving plates 30 to move closer to or away from each other. The connecting rod 23 can rotate within a certain range on the surface of the sliding block 22 to ensure that the two moving plates 30 make the clamping accommodating frame 31 move closer to or away from each other.

[0036] In some preferred embodiments, a connecting plate 300 is provided at the bottom of the movable plate 30, and the connecting plate 300 is hinged to the connecting rod 23. Specifically, the connecting plate 300 is hinged to the connecting rod 23, and when the driving motor is started, the angle between the connecting rod 23 and the connecting plate 300 changes within a certain range, thereby adapting to the movement of the movable plate 30.

[0037] When the utility model is used, firstly one of the clamping plates 32 is moved in the direction of the spring 33 to reserve a larger space for placing the power amplifier chip. When the power amplifier chip is placed in the clamping accommodating frame 31, under the elastic action of the spring 33, the clamping plates 32 on both sides are effectively clamped. The rubber pads 35 arranged on the sides of the clamping plates 32 effectively protect the power amplifier chip from being damaged. At the same time, a stabilizing plate 36 with a rubber pad 35 is arranged on the bottom surface of the power amplifier chip. The stabilizing plate 36 provides a supporting force for the bottom of the power amplifier chip; thereby, the driving motor drives the screw rod 21 to rotate, so that the sliding block 22 moves, so as to drive the moving plates 30 to move closer to or away from each other, so that the spacing between the two moving plates 30 adapts to the size of the power amplifier chip. At the same time, during the removal process, the driving motor is turned on again to move the two moving plates 30 away from each other, so as to ensure that the power amplifier chip is located above the stabilizing plate 36, and push one of the clamping plates 32 to be removed. The utility model adopts a clamping and placing frame provided in the clamping assembly 3, and the clamping plate 32 and the spring 33 cooperate with each other to adapt to power amplifier chips of different widths, and at the same time the stabilizing plate 36 below provides horizontal support; the sliding assembly 2 connects the movable plate 30 through the sliding block 22, the connecting rod 23 and the connecting block, so that the two movable plates 30 move relative to each other to adapt to power amplifier chips of different lengths, which can effectively improve the utilization rate of the device, facilitate taking, and have high work efficiency.

[0038] The above is only a preferred embodiment of the utility model and does not limit the utility model in any form. According to the technical essence of the utility model, within the spirit and principles of the utility model, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the utility model.
