Description
Technical Field
[0001] The utility model relates to the technical field of clamping fixtures, in particular to a novel horizontal clamping fixture. Background Art
[0002] After the chip is packaged into a module, the optoelectronic performance needs to be tested. Since the power supply electrode of the module is on the bottom of the module and the electrode size is very small, at the level of hundreds of microns, a very small spring probe is needed for power supply; the front of the module is the light-emitting surface, and the divergence angle is generally greater than 110°, so the fixture cannot be pressed from top to bottom like a conventional structure when fixing the module; the appearance of the module is made of a relatively soft material, and it is easy to get scratches during the clamping process, causing defects, so a special structure is needed to avoid scratches. In view of the above three difficulties, it is particularly important to design a new fixture. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0023] Reference Figure 1-Figure 5A novel horizontal clamping fixture comprises a base plate 1, on which are provided:
[0024] The power supply component 2 is plate-shaped as a whole according to the distribution of the pads on the bottom surface of the module, and a spring probe 3 and a fixed clamping seat 4 are arranged on its surface, and the fixed clamping seat 4 is located on one side of the spring probe 3, wherein the spring probe 3 structure is embedded in the top of the power supply component 2, and the fixed clamping seat 4 is fixedly installed on the top of the power supply component 2, and the position of the power supply component 2 where the spring probe 3 is arranged is through-shaped, and the position corresponding to the position of the bottom plate 1 is also through-shaped, and the spring probe 3 is installed on the probe station, and the probe station is connected to an external power supply device through this position;
[0025] The spring clamping assembly 5 is plate-shaped as a whole and is located on one side of the power supply assembly 2. A spring column 6 is provided on its surface, and a movable clamping seat 7 is provided at one end of the spring column 6. The movable clamping seat 7 is adapted to the fixed clamping seat 4. A wear-resistant block 8 is provided on the top of the movable clamping seat 7. The spring column 6 adopts an elastically adjustable spring column 6 to facilitate the adjustment of the clamping force. The spring clamping assembly 5 is embedded in the top of the bottom plate 1.
[0026] The clamping and resetting assembly 9 is plate-shaped as a whole and is located on the other side of the spring clamping assembly 5. A cylinder 10 is installed on its surface, and a movable plate 11 is installed on the driving end of the cylinder 10. A roller 12 is rotatably installed on the end of the movable plate 11 through a bearing, and the roller 12 is movably abutted against the side of the wear-resistant block 8. The wear-resistant block 8 is tangent to the roller 12 of the clamping and resetting assembly 9. When the cylinder 10 in the clamping and resetting assembly 9 contracts, it pushes the wear-resistant block 8 together with the movable clamping seat 7 to move, thereby loosening the module.
[0027] This fixture is a tooling for clamping a module (module: a product after chip packaging) and then providing a specified test temperature for the module and conducting an electrical test on the module. When in use, first control the cylinder 10 in the clamping reset assembly 9 to perform a contraction movement, so that the mobile clamping seat 7 is separated from the fixed clamping seat 4 at this time, and then the module to be assembled is placed on the needle film 13 and contacts the fixed clamping block. At this time, the cylinder 10 cylinder rod performs a stretching movement, pushing the roller 12 to abut against the wear-resistant block 8, so that the mobile clamping seat 7 performs a horizontal movement under the push of the elastic force of the spring column 6, thereby realizing the movement. The dynamic clamping seat 7 cooperates with the fixed clamping seat 4 in a side-pushing manner to clamp the chip module. After the module is clamped by the side, the module pad is aligned with the position of the spring probe 3. At this time, the fixed clamping seat 4 and the needle membrane 13 are already at the set temperature. The spring probe 3 is energized and tested at the set temperature. After the test is completed, the cylinder rod of the clamping reset assembly 9 cylinder 10 performs a contraction movement. At this time, the mobile clamping seat 7 is moved away from the fixed clamping seat 4, and the module is removed. Compared with the prior art, the clamp will not block the chip surface, solving the problem of the previous clamp structure blocking the light-emitting surface.
[0028] In this embodiment, the power supply component 2 also includes a needle membrane 13. The needle membrane 13 is made of polytetrafluoroethylene and has good chemical stability, high temperature resistance and electrical insulation properties. A microporous structure for fixing the spring probe 3 is provided on the surface of the needle membrane 13, and the micropore distribution of the microporous structure corresponds to the distribution of the spring probe 3. The spring probe 3 passes through the hole of the needle membrane 13 to contact the module to form an electrical connection, and both ends of the spring probe 3 are elastic and can be compressed appropriately.
[0029] In this embodiment, the spring clamping assembly 5 further includes a linear guide rail 14 arranged on its surface, and the bottom of the movable clamping seat 7 is slidably connected to the linear guide rail 14 to provide a guide for the displacement of the movable clamping seat 7.
[0030] In this embodiment, a heating element 15 and a temperature sensor 16 are provided inside the power supply component 2, and the heating element 15 and the temperature sensor 16 are extended to the outside of the power supply component 2 through the opening on the outside of the power supply component 2. The heating element 15 adopts an electric heating rod for heating, and the temperature sensor 16 monitors the ambient temperature. When the set temperature is detected, the heating of the electric heating rod is stopped by controlling the processor, thereby providing a corresponding temperature environment for the module test.
[0031] In this embodiment, the fixed clamping seat 4 and the movable clamping seat 7 are both made of brass to avoid scratches on the surface of the module. The opening shapes of the opposite ends of the fixed clamping seat 4 and the movable clamping seat 7 are both V-shaped, and the shape depends on the external dimensions of the module.
[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
