[0036] Such as Figures 1 to 5As shown together, this embodiment provides a pull - cover fixture device with a degumming function. This pull - cover fixture device with a degumming function includes a fixture main body 1 and a cross - beam 2. The cross - beam 2 is located at the top of the fixture main body 1. A first threaded sleeve 3 is also provided at the top of the fixture main body 1. The first threaded sleeve 3 is installed in the middle of the fixture main body 1. One end of the first threaded sleeve 3 passes through the cross - beam 2 and is fixedly installed with a rotating shaft 4. A second threaded sleeve 5 is provided on the outer side of the rotating shaft 4. A lifting slider 6 is installed on the outer side of the second threaded sleeve 5, and the lifting slider 6 is threadedly connected to the second threaded sleeve 5. Clamping blocks 7 are symmetrically distributed on both sides of the fixture main body 1. Connecting rods 8 are hinged to the tops of the clamping blocks 7. The clamping blocks 7 are hinged to the lifting slider 6 through the connecting rods 8. The cross - beam 2 and the fixture main body 1 are horizontally arranged. The heat - dissipation cover in the fixture main body 1 is placed in a groove embedded in the fixture main body 1. The first threaded sleeve 3 penetrates through the cross - beam 2 as a whole. When the first threaded sleeve 3 rotates, the rotating shaft 4 rotates synchronously with the first threaded sleeve 3. When the second threaded sleeve 5 rotates, the lifting slider 6 can rotate along the surface of the second threaded sleeve 5 and pull the clamping blocks 7 through the connecting rods 8 to approach the heat - dissipation cover in the groove of the fixture main body 1 and finally complete the clamping of the heat - dissipation cover, thus eliminating the need for manual fixing of the heat - dissipation cover.

[0037] A rotating groove 9 is provided at one end of the rotating shaft 4 close to the first threaded sleeve 3. A collar 10 is fixedly installed at the top of the second threaded sleeve 5, and the second threaded sleeve 5 is movably connected to the outside of the rotating groove 9 through the collar 10. The second threaded sleeve 5 can be transferred in the rotating groove 9 through the collar 10, so that when the second threaded sleeve 5 rotates on the rotating shaft 4, the first threaded sleeve 3 at the top of the rotating shaft 4 does not rotate.

[0038] The diameter of the rotating groove 9 is smaller than the diameter of the rotating shaft 4 and is the same as the inner - ring diameter of the collar 10. One end of the rotating shaft 4 far from the first threaded sleeve 3 protrudes from one end of the second threaded sleeve 5 far from the collar 10. The second threaded sleeve 5 can rotate on the rotating groove 9 in the rotating shaft 4 through the collar 10 but always remains on the rotating shaft 4, does not disengage from the rotating shaft 4, and the vertical height remains unchanged.

[0039] Limit shafts 11 are fixedly installed on the sides of the clamping blocks 7 far from the second threaded sleeve 5. Arm guards 12 are symmetrically distributed at both ends of the cross - beam 2. One end of the limit shaft 11 penetrates through the arm guards 12 as a whole. When the limit shaft 11 moves under the restriction of the arm guards 12, it always remains on the same straight line, so that when clamping the heat - dissipation cover in the fixture main body 1, the angles on both sides remain horizontal.

[0040] The limit shafts 11 are arranged parallel to the cross - beam 2. The limit shafts 11 correspond to the arm guards 12 one by one, and the included angle between them and the arm guards 12 is ninety degrees. The arm guards 12 are connected to the fixed points on the fixture main body 1, providing support during the operation of the device, ensuring the stable operation of the device, and preventing the tester from directly contacting the heat - dissipation cover, thus ensuring the use safety.

[0041] On the side of the clamping block 7 away from the limit shaft 11, an arc-shaped groove 13 is provided. At the bottom of the arc-shaped groove 13, a positioning groove 14 is provided, and the arc-shaped grooves 13 and the positioning grooves 14 are in one-to-one correspondence. The shape of the arc-shaped groove 13 corresponds to that of the heat dissipation cover, and the bottom of the arc-shaped groove 13 is sheet-shaped, which is convenient for inserting from the bottom of the heat dissipation cover in the fixture body 1. After the positioning groove 14 completes the clamping, it corresponds to the central hole of the heat dissipation cover in the fixture body 1, so as to ensure the accuracy of the degumming work of the heat dissipation cover. After the heat dissipation cover is clamped, the heat dissipation cover does not contact the inner side of the clamping block 7, but only lies in the arc-shaped groove 13.

[0042] The first threaded sleeve 3 penetrates through the whole cross beam 2 and is threadedly connected to the cross beam 2. A pressing member 15 is installed at one end of the first threaded sleeve 3 away from the rotating shaft 4. The first threaded sleeve 3 can rotate in the middle of the cross beam 2. On the premise that the position of the cross beam 2 remains unchanged, the initial height between the rotating shaft 4 and the fixture body 1 is changed, so that the height change between the lifting slider 6 on the second threaded sleeve 5 and the fixture body 1 is changed, so that the maximum distance of the clamping block 7 moving on the fixture body 1 is changed, to adapt to the clamping requirements of heat dissipation covers of different sizes.

[0043] The pressing member 15 is a hydraulic cylinder, and its telescopic end is the pressing end. The telescopic end of the pressing member 15 protrudes from one end of the rotating shaft 4 away from the first threaded sleeve 3. After the heat dissipation cover in the fixture body 1 is clamped, the length of the pressing member 15 protruding from the rotating shaft 4 can be increased. After passing through the middle hole of the heat dissipation cover in the fixture body 1, by pressing the fixture body 1, sufficient thrust can be generated, and then the heat dissipation cover can be smoothly peeled off from the fixture. The automatic pulling and degumming functions significantly shorten the peeling time of the heat dissipation cover from the fixture body 1 and improve the testing efficiency.

[0044] During use, the collar 10 connected to the second threaded sleeve 5 enables the second threaded sleeve 5 to rotate in the rotation groove 9 of the rotating shaft 4. Without rotating the first threaded sleeve 3, the height between the second threaded sleeve 5 and the fixture body 1 remains unchanged. The lifting slider 6 threadedly connected to the second threaded sleeve 5 moves along the outer side of the second threaded sleeve 5, and through the connecting rod 8 hinged at both ends, the clamping block 7 is pulled to approach the heat dissipation cover adhesively attached to the fixture body 1 in the groove of the fixture body 1, and finally the clamping of the heat dissipation cover is completed. Thus, it is not necessary to manually fix the heat dissipation cover. During this process, there is no need to manually clamp and separate the heat dissipation cover and the fixture, thereby avoiding damage to the heat dissipation cover or the fixture, ensuring the test efficiency and product quality. During this process, the limiting shaft 11, which is restricted by the protective arm 12 and horizontally arranged with the cross beam 2, enables the clamping block 7 to move in a straight line in the groove of the fixture body 1. And when the heat dissipation cover is located in the arc-shaped groove 13 and does not contact the inner side of the clamping block 7, when the positioning groove 14 after splicing corresponds to the central hole of the heat dissipation cover, the clamping of the heat dissipation cover is completed. Thus, while ensuring that the angles on both sides of the heat dissipation cover are horizontal, the precision of the degumming work of the heat dissipation cover is ensured. By connecting the protective arm 12 to the fixed point in the fixture body 1, support is provided for the entire device, and direct contact between the tester and the heat dissipation cover is avoided, thereby ensuring the use safety. By rotating the first threaded sleeve 3, the distance between the rotating shaft 4 and the fixture body 1 changes, causing the overall height between the lifting slider 6 on the second threaded sleeve 5 and the fixture body 1 to change, so that the maximum distance of movement of the clamping block 7 on the fixture body 1 changes, adapting to the clamping requirements of heat dissipation covers of different sizes. After the hydraulic-driven pressing member 15 completes the clamping of the heat dissipation cover in the fixture body 1, the length protruding from the rotating shaft 4 increases. After passing through the central hole of the heat dissipation cover in the fixture body 1, by pressing the fixture body 1, sufficient thrust is generated, and then the heat dissipation cover is smoothly peeled off from the fixture. The automated pulling and degumming functions significantly shorten the peeling time of the heat dissipation cover from the fixture body 1 and improve the test efficiency.

In addition, it should also be understood that after reading the technical content of the present invention, those skilled in the art can make various changes, modifications, and / or variations to the present invention, and all these equivalent forms also fall within the protection scope defined by the appended claims of this application.
