Description

Technical Field

[0001] The utility model relates to the field of chip processing, in particular to an electronic component accessory clamp for computer chips. Background Art

[0002] The computer chip manufacturing industry needs to test a large number of chips produced to ensure that the performance of the chips leaving the factory is intact. During the chip research and development process, the chip also needs to be tested for performance indicators such as the degree of chip aging. This test usually requires the chip to be fixed in a fixture, and a number of probes on the fixture that correspond to the chip pins one by one are used to contact the chip pins. The probes are then connected to the circuit, thereby testing the chip performance through the circuit.

[0003] Computer chips are small and easily damaged, so they are usually clamped and fixed one by one using a single fixture for inspection. Operators need to repeatedly place and remove the chips, which makes this inspection method very inefficient and is not conducive to mass computer chip inspection.

[0004] Therefore, in view of the fact that the fixture currently used for computer chip testing can only fix and test a single chip at a time, which is inefficient in the face of large-scale testing work, an electronic component fixture can be designed that can quickly position multiple computer chips to improve the efficiency of batch testing. Utility Model Content

[0005] In order to overcome the problem that the fixtures currently used for computer chip testing can only fix and test a single chip at a time, which is inefficient in the face of large-scale testing work.

[0006] The technical scheme of the utility model is: an electronic component accessory fixture for computer chips, comprising a base, a transmission bin integrally formed on the upper end of the base, a placement platform, a back plate and a synchronous transmission mechanism; the transmission bin is a hollow structure and a synchronous transmission mechanism consisting of an outer gear ring, a driven gear and a screw is arranged inside and above the transmission bin, eight placement platforms are distributed around the upper end of the transmission bin, a side of the placement platform facing the edge of the transmission bin is fixedly connected with the back plate, the computer chip is placed on the placement platform and abuts against the side wall of the back plate, the outer wall and the inner wall of the outer gear ring are both provided with tooth grooves, the outer gear ring is rotatably connected to the inner side of the transmission bin, eight driven gears are arranged and one-to-one correspondence is arranged below the placement platform, the driven gears are respectively meshed and connected with the tooth grooves on the inner wall of the outer gear ring, the upper end of the driven gear is fixedly connected with a screw extending from the top wall of the transmission bin, the screw is threadedly connected with a jacket located above the placement platform, a driving bin is arranged on one side of the transmission bin, and a driving gear meshed and connected with the tooth grooves on the outer wall of the outer gear ring is arranged in the driving bin.

[0007] Preferably, a computer chip or other electronic component is placed on the placement table with one end thereof against the back plate, keeping the pins of the chip exposed on both sides of the placement table, and then the outer gear ring is driven to rotate by the rotation of the driving gear, and the outer gear ring then drives the driven gears meshing with the inner wall teeth to rotate. Correspondingly, the screw on the driven gear rotates synchronously in one direction, and the jacket thereon moves vertically up and down through the threaded transmission. When it moves downward, it gradually approaches the computer chip on the placement table until it is pressed against the surface of the computer chip. A circle of silicone ring is provided on the lower edge of the jacket, which will be squeezed, deformed and expanded after contacting the computer chip, thereby increasing the contact area and improving the friction locking force. At the same time, the contact between the rubber ring and the computer chip is flexible contact, which is not easy to cause damage to the chip.

[0008] Preferably, a motor is installed at the upper end of the driving bin, and the transmission shaft of the motor extends into the driving bin and is fixedly connected to the driving gear. The motor drives the driving gear to rotate and drives the outer gear ring through meshing transmission. The motor drives the driving gear to rotate, and the driving gear drives the outer gear ring to rotate. The outer gear ring then drives the driven gear to rotate synchronously through the meshing transmission of its inner wall tooth groove and the driven gear, thereby controlling the rotation of the screw and forcing the jacket on the screw to move vertically up and down.

[0009] Preferably, a swivel is provided at the upper end of the outer gear ring, and the swivel is rotatably connected to the swivel groove on the top wall of the transmission bin. A rotating shaft is provided at the lower end of the driven gear and is rotatably connected to the corresponding rotating hole on the base through the rotating shaft. The outer gear ring and the driven gear rotate stably in the transmission bin through the swivel and the rotating shaft respectively, and maintain their relative positions without shaking or deviation.

[0010] Preferably, eight guide rods corresponding to the mounting table are fixedly connected to the upper end of the transmission bin, and a clamping hole is provided on the jacket. The guide rods are inserted into the corresponding clamping holes and limit the jacket. The guide rods serve as a guiding and limiting structure for the jacket, so that when the screw rotates, the jacket will not rotate along with the screw due to friction, thereby maintaining the vertical up and down movement of the jacket.

[0011] Preferably, the guide rod is arranged parallel to one side of the screw, the upper end of the guide rod is fixedly connected to the end plate, the upper end of the screw is fixedly connected to the shaft head, the shaft head is rotatably connected in the end plate, and the upper end of the screw further improves its own rotational stability through the movable connection with the end plate to avoid large shaking.

[0012] Preferably, a top plate is provided above the transmission bin. The top plate is a hollow structure and the hollow buckle groove is located above the screw and the guide rod. Eight probe heads are installed around the lower end of the top plate and are opposite to the mounting platform. The probe heads are connected to the chip pins on the mounting platform and powered on for detection. The probe head 5 moves downward with the top plate until it contacts the pins on the chip to be detected. The probe head 5 is connected to the circuit and then starts to detect the chip to be detected.

[0013] Preferably, a cylinder is fixedly installed in the middle of the upper end of the transmission bin, and a protective cover is provided on the outer sleeve of the cylinder. The piston rod of the cylinder extends out of the protective cover and is fixedly connected to the top plate above. The vertical movement of the top plate is controlled by the cylinder. When the piston is extended, the top plate rises and the probe head leaves the chip to be detected. When the piston is contracted, the top plate descends and the probe head approaches the chip to be detected.

[0014] Beneficial effects of the utility model:

[0015] 1. The active gear drives the outer gear ring and then synchronously drives multiple driven gears to control the vertical lifting of the jacket along the screw rod, which can simultaneously press multiple computer chips to be tested, facilitating batch testing. Compared with the traditional one-by-one clamping and locking testing, the testing efficiency is greatly improved;

[0016] 2. The original opposite clamping and locking method is replaced by the clamping and fixing method. The chip is subjected to unidirectional force and evenly transmitted to the placement table. Compared with the method of clamping the computer chip in the air, it is less likely to cause damage to it. BRIEF DESCRIPTION OF THE DRAWINGS

After contacting the computer chip, it will be squeezed, deformed and expanded to increase the contact area and improve the friction locking force. At the same time, the contact between the rubber ring and the computer chip is flexible contact, which is not easy to cause chip damage.

[0026] See also Figure 1-Figure 2 , Figure 4-Figure 5In this embodiment, a motor 11 is installed at the upper end of the driving bin 9, and the transmission shaft of the motor 11 extends into the driving bin 9 and is fixedly connected to the driving gear 10. The motor 11 drives the driving gear 10 to rotate and drives the outer gear ring 5 through meshing transmission. The motor 11 drives the driving gear 10 to rotate, and the driving gear 10 drives the outer gear ring 5 to rotate.

[0027] See also Figure 1-Figure 5 In this embodiment, eight guide rods 12 corresponding to the placement platform 3 are fixedly connected to the upper end of the transmission warehouse 2.

A protective cover 19 is provided on the outer cover of the cylinder 18. The piston rod of the cylinder 18 extends out of the protective cover 19 and is fixedly connected to the top plate 16 above. The vertical movement of the top plate 16 is controlled by the cylinder 18. The extension of the piston causes the top plate 16 to rise, and the probe head 17 leaves the chip to be detected. The piston contracts, the top plate 16 descends, and the probe head 17 approaches the chip to be detected.
