Implementation

[0020] The present invention can be further understood through the specific embodiments given below, but they are not intended to limit the present invention.

[0021] Embodiment 1: A chip pressure test seat, comprising: a seat body 1, a mounting groove 2 is formed on the top of the seat body 1, and a pressure sensor 5 is arranged on the bottom inner wall of the mounting groove 2, a top plate 4 is arranged inside the mounting groove 2 and above the pressure sensor 5, and a first elastic member 6 is arranged between the top plate 4 and the bottom of the mounting groove 2;

[0022] The staff first places the chip to be tested on the upper surface of the top plate, and then presses the chip to be tested into the mounting groove, thereby driving the top plate to move downward and compressing the first elastic member. When the chip to be tested is completely inserted into the mounting groove, the upper surface of the chip to be tested is lower than the upper surface of the seat body, and the top plate is completely separated from the fixing block. At this time, the fixing block is reset and moves toward the chip to be tested under the action of the elastic restoring force of the third elastic member, thereby fixing the chip to be tested in the middle of the upper surface of the top plate;

[0023] A connecting groove 15 is respectively provided on two opposite inner walls of the mounting groove 2. One end of a fixing block 9 can pass through the connecting groove 15 and extend into the interior of the mounting groove 2. The other end of the fixing block 9 is located outside the base 1 and is fixedly connected to a limiting plate 8. A third elastic member 7 is provided between the limiting plate 8 and the outer wall of the base 1. When the lower surface of the fixing block 9 contacts the upper surface of the top plate 4, the upper surface of the chip to be tested 3 placed on the top plate 4 is flush with the surface of the base 1, and the first elastic member 6 is in a compressed state.

[0024] The pressure sensor is pressed downward to release the pressure from the pressure sensor, and the pressure on the chip to be tested is then observed. When a pressure test is completed, the staff member squeezes the fixing frame toward one side of the seat body. At this time, the second elastic member is gradually compressed, and the side plate of the fixing frame drives the push block to contact the limit plate and squeeze the limit plate. The limit plate moves to the side away from the seat body under the squeezing of the push block, thereby driving the fixing block to move in the connecting groove, and the fixing block is separated from the top plate. At this time, the fixing block no longer limits the top plate, and the top plate resets upward under the action of the elastic restoring force of the first elastic member itself, and drives the chip to be tested on its top to move upward to the top of the seat body and separate from the mounting groove. At this time, the staff member can directly remove the chip to be tested from the surface of the top plate, and there is no need to use tweezers to remove the chip to be tested from the mounting groove. This is convenient and quick, thereby improving work efficiency.

[0025] A slide groove 14 is provided on one side of the connecting groove 15 and on the outer wall of the seat body 1 , and a push block 13 for pushing the limiting plate 8 away from the mounting groove 2 is slidably connected to the slide groove 14 .

[0026] The push block 13 is provided with a guide inclined surface 16 on one side thereof opposite to the limiting plate 8 .

[0027] A slider 17 is slidably connected inside the slide groove 14 , and the slider 17 is fixedly connected to the push block 13 via a fixing plate 10 .

[0028] One end of the fixing block 9 close to the top plate 4 has an arc-shaped end surface.

[0029] Embodiment 2: A chip pressure test seat, comprising: a seat body 1, a mounting groove 2 is formed on the top of the seat body 1, and a pressure sensor 5 is arranged on the bottom inner wall of the mounting groove 2, a top plate 4 is arranged inside the mounting groove 2 and above the pressure sensor 5, and a first elastic member 6 is arranged between the top plate 4 and the bottom of the mounting groove 2;

[0030] The position of the chip to be tested is positioned, and its pressed position will not be offset, so as to ensure that the subsequent detection operation of the chip to be tested can be carried out normally. At this time, the lower surface of the fixed block will contact with the upper surface of the top plate and limit it to prevent it from moving upward under the elastic force of the first elastic member;

[0031] A connecting groove 15 is respectively provided on two opposite inner walls of the mounting groove 2. One end of a fixing block 9 can pass through the connecting groove 15 and extend into the interior of the mounting groove 2. The other end of the fixing block 9 is located outside the base 1 and is fixedly connected to a limiting plate 8. A third elastic member 7 is provided between the limiting plate 8 and the outer wall of the base 1. When the lower surface of the fixing block 9 contacts the upper surface of the top plate 4, the upper surface of the chip to be tested 3 placed on the top plate 4 is flush with the surface of the base 1, and the first elastic member 6 is in a compressed state.

[0032] By opening a connecting groove inside the mounting groove, and one end of a fixed block slidably connected inside the connecting groove can limit the top plate, it is convenient to place the chip to be tested on the top plate, and after the test is completed, the limiting plate can be pulled open so that the top plate can continue to lift the chip, thereby realizing segmented lifting of the chip, reducing the impact force of the chip rising upward, greatly reducing the situation where the chip pops up, and also facilitating the chip to be exposed from the mounting groove, which is beneficial to improving the efficiency of chip picking.

[0033] A slide groove 14 is provided on one side of the connecting groove 15 and on the outer wall of the seat body 1 , and a push block 13 for pushing the limiting plate 8 away from the mounting groove 2 is slidably connected to the slide groove 14 .

[0034] The push block 13 is provided with a guide inclined surface 16 on one side thereof opposite to the limiting plate 8 .

[0035] A slider 17 is slidably connected inside the slide groove 14 , and the slider 17 is fixedly connected to the push block 13 via a fixing plate 10 .

[0036] The two fixing plates 10 located on both sides of the base body 1 are fixedly connected via a connecting plate 11 , and a plurality of second elastic members 12 are disposed between the connecting plate 11 and the base body 1 .

[0037] There are two third elastic members 7 , and the two third elastic members 7 are symmetrically arranged above and below the fixing block 9 .

[0038] The working principle is:

[0039] When in use, the staff first places the chip to be tested on the upper surface of the top plate, and then presses the chip to be tested into the installation groove, thereby driving the top plate to move downward and compressing the first elastic member. When the chip to be tested completely enters the installation groove, the upper surface of the chip to be tested is lower than the upper surface of the seat body, and the top plate is completely separated from the fixing block. At this time, the fixing block is reset and moves toward the chip to be tested under the action of the elastic restoring force of the third elastic member, thereby fixing the chip to be tested in the middle of the upper surface of the top plate, positioning the position of the chip to be tested, and its compressed position will not be offset, ensuring that subsequent detection operations of the chip to be tested can be carried out normally, and at this time, the lower surface of the fixing block will contact the upper surface of the top plate and limit it to prevent it from moving upward under the action of the elastic force of the first elastic member;

[0040] Then, press the chip to be tested downward and make its lower surface contact with the pressure sensor, and the pressure condition of the chip to be tested at this time can be observed. When a pressure detection operation is completed, the staff will squeeze the fixing frame toward one side of the seat body. At this time, the second elastic member is gradually compressed, and the side plate of the fixing frame will drive the push block to contact with the limit plate and squeeze the limit plate. The limit plate will move to the side away from the seat body under the squeezing of the push block, thereby driving the fixing block to move in the connecting groove, and the fixing block is separated from the top plate. At this time, the fixing block no longer limits the top plate, and the top plate resets upward under the action of the elastic restoring force of the first elastic member itself, and drives the chip to be tested on its top to move upward to the top of the seat body and separate from the mounting groove. At this time, the staff can directly remove the chip to be tested from the surface of the top plate, and there is no need to use tweezers to remove the chip to be tested from the mounting groove. It is convenient and quick, thereby improving work efficiency.

[0041] When the above-mentioned chip pressure test seat is used, a connecting groove is opened inside the mounting groove, and one end of a fixed block slidably connected inside the connecting groove can limit the top plate, so that the chip to be tested can be placed on the top plate. After the test is completed, the limiting plate can be pulled open so that the top plate can continue to lift the chip, thereby realizing segmented lifting of the chip, reducing the impact force of the chip rising upward, greatly reducing the situation where the chip pops up, and facilitating the chip to be exposed from the mounting groove, which is beneficial to improving the efficiency of chip picking.

[0042] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
