Description
Technical Field
[0001] This utility model relates to the field of integrated circuit testing technology, specifically a positioning device for testing multi-chip integrated circuits. Background Technology
[0002] In today's highly developed electronic information age, integrated circuits, as the core components of electronic devices, directly determine the reliability and stability of the entire electronic system through their performance and quality. With the rapid advancement of technology, multi-chip integrated circuits have emerged, integrating multiple chips with different functions into a single package, achieving higher integration, stronger processing capabilities, and richer functionality. Testing of multi-chip integrated circuits is a crucial step in their production process.
[0003] Currently, some positioning devices for testing multi-chip integrated circuits on the market suffer from low positioning accuracy. Multi-chip integrated circuits have a compact chip layout, densely packed test points, and tiny dimensions, requiring extremely high positioning accuracy. Some traditional positioning devices, due to insufficient structural design or outdated positioning technology, are prone to deviations during the positioning process, causing test probes to fail to accurately contact the test points. This not only affects the accuracy of test results but may also damage the chip due to misaligned contact between the probe and the test point, resulting in unnecessary economic losses. Utility Model Content
[0004] The purpose of this invention is to provide a positioning device for testing multi-chip integrated circuits, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for testing multi-chip integrated circuits, comprising a mounting housing, a rotating seat 1 rotatably mounted inside the mounting housing, four placement slots on the outer side of the rotating seat 1, a protective vertical shell fixedly mounted on one side of the mounting housing, a transmission assembly installed inside the protective vertical shell, a connecting pipe connected to one side of the protective vertical shell, a protective cover connected to the end of the connecting pipe away from the protective vertical shell, a fixed connecting rod fixedly mounted inside the protective vertical shell, a projection lamp fixedly mounted inside the fixed connecting rod extending through the connecting pipe to the interior of the protective cover at the end of the fixed connecting rod away from the protective vertical shell, and a rotating seat 2 rotatably mounted inside the protective cover, four positioning screens fixedly mounted on the outer side of the rotating seat 2.
[0006] Preferably, the transmission assembly includes a driving wheel and a driven ring. Both the driving wheel and the driven ring are rotatably mounted on the inner side of the protective vertical shell. A transmission belt is sleeved on the outer side of the driving wheel and the driven ring. A bent rod is fixedly mounted on one side of the driven ring. The end of the bent rod away from the driven ring is in contact with the rotating seat.
[0007] Preferably, the projection lamp is located inside the rotating base two, and the centers of the projection lamp, the rotating base two, and the rotating base one are on the same vertical line.
[0008] Preferably, one side of the drive wheel is fixedly connected to one side of the rotating seat, a rotating handle is fixedly installed at the end of the rotating seat away from the drive wheel, four magnets are fixedly installed on one side of the mounting housing, and a magnet is fixedly installed on the side of the rotating handle connected to the rotating seat, with the magnetic poles of the opposite sides of the magnets being opposite.
[0009] Preferably, a rubber ring is fixedly installed inside each of the four placement slots.
[0010] Preferably, the bottom of the mounting housing is fixedly equipped with four support legs, which are installed in a rectangular symmetrical arrangement at the four corners of the bottom of the mounting housing.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by placing the circuit board to be tested inside the placement slot, the rubber ring inside the placement slot can protect the circuit board to be tested. Then, the projection lamp is turned on, and the projection lamp can project onto the circuit board to be tested placed inside the placement slot through the positioning screen, thereby projecting the test points onto the top of the circuit board to be tested, thereby locating the test points of the circuit board to be tested, improving the subsequent test effect, and the positioning will not damage the circuit board to be tested, ensuring the test accuracy of the circuit board.
[0012] Additionally, when projecting and positioning circuit boards of different sizes, the handle can be turned to rotate the first rotating seat inside the mounting housing, thereby rotating the placement slot of the required size to the top. When the first rotating seat rotates, it can drive the drive wheel to rotate, which in turn drives the driven ring to rotate via the transmission belt, which in turn drives the second rotating seat to rotate via the bending rod, thereby rotating the corresponding positioning screen directly below the projection lamp, thus achieving the positioning of circuit boards of different sizes to be tested.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-4 This utility model provides a technical solution: a positioning device for testing multi-chip integrated circuits, including a mounting shell 1, a rotating seat 2 rotatably mounted inside the mounting shell 1, four placement slots 9 on the outer side of the rotating seat 2, a protective vertical shell 3 fixedly mounted on one side of the mounting shell 1, a transmission assembly installed inside the protective vertical shell 3, a connecting pipe 5 connected to one side of the protective vertical shell 3, a protective cover 4 connected to the end of the connecting pipe 5 away from the protective vertical shell 3, a fixed connecting rod 17 fixedly mounted inside the protective vertical shell 3, the end of the fixed connecting rod 17 away from the protective vertical shell 3 extending through the connecting pipe 5 to the inside of the protective cover 4, where a projection lamp 19 is fixedly mounted. The rotating seat 11 is rotatably mounted inside the rotating seat 11. Four positioning screens 10 are fixedly mounted on the outside of the rotating seat 11. The transmission assembly includes a drive wheel 14 and a driven ring 16. Both the drive wheel 14 and the driven ring 16 are rotatably mounted inside the protective vertical shell 3. A transmission belt 15 is sleeved on the outside of the drive wheel 14 and the driven ring 16. A bent rod 18 is fixedly mounted on one side of the driven ring 16. The end of the bent rod 18 away from the driven ring 16 is in contact with the rotating seat 11. The projection lamp 19 is located inside the rotating seat 11. The centers of the projection lamp 19, the rotating seat 11, and the rotating seat 2 are on the same vertical line. Rubber rings 7 are fixedly mounted inside the four placement slots 9.
[0020] The working principle of the above technical solution is as follows: First, the circuit board to be tested is placed inside the placement slot 9. The rubber ring 7 inside the placement slot 9 can protect the circuit board to be tested. Then, the projection lamp 19 is turned on. The projection lamp 19 can project onto the circuit board to be tested placed inside the placement slot 9 through the positioning screen 10, thereby projecting the test points onto the top of the circuit board to be tested, thus locating the test points of the circuit board to be tested, improving the subsequent test effect, and the positioning will not damage the circuit board to be tested, ensuring the test accuracy of the circuit board. In addition, when it is necessary to project and locate circuit boards of different sizes, the rotating handle 8 can be turned to drive the rotating seat 2 to rotate inside the mounting housing 1, thereby rotating the placement slot 9 of the required size to the top. When the rotating seat 2 rotates, it can drive the drive wheel 14 to rotate, thereby driving the driven ring 16 to rotate through the transmission belt 15, thereby driving the rotating seat 11 to rotate through the bending rod 18, thereby rotating the corresponding positioning screen 10 to the bottom of the projection lamp 19, thus realizing the positioning of circuit boards of different sizes to be tested.
[0021] In another implementation scheme, such as Figures 1-4 As shown, one side of the drive wheel 14 is fixedly connected to one side of the rotating seat 2. A rotating handle 8 is fixedly installed on the end of the rotating seat 2 away from the drive wheel 14. Four magnets 13 are fixedly installed on one side of the mounting housing 1. A magnet 2 is fixedly installed on the side of the rotating handle 8 connected to the rotating seat 2, and the magnetic poles of the opposite sides of the magnet 2 and the magnet 13 are opposite.
[0022] The magnets 13 and 2 can be used to fix the rotating handle 8 when it is turned, thereby fixing the position of the rotating seat 2 and preventing it from rotating during use.
[0023] In another implementation scheme, such as Figures 1-4 As shown, four support legs 6 are fixedly installed at the bottom of the mounting housing 1, and the four support legs 6 are installed in a rectangular symmetrical arrangement at the four corners of the bottom of the mounting housing 1.
[0024] The support legs 6 provide overall support for the device, ensuring its normal operation.
[0025] Working principle: First, the circuit board to be tested is placed inside the placement slot 9. The rubber ring 7 inside the placement slot 9 protects the circuit board. Then, the projection lamp 19 is turned on. The projection lamp 19 projects onto the circuit board placed inside the placement slot 9 through the positioning screen 10, thus projecting the test points onto the top of the circuit board. This locates the test points on the circuit board, improving the subsequent testing effect. Moreover, the positioning does not damage the circuit board, ensuring the accuracy of the circuit board test. In addition, when it is necessary to project and position circuit boards of different sizes, the rotating handle 8 can be rotated to drive the rotating seat 2 to rotate inside the mounting housing 1, thereby positioning the circuit board. When the required size placement slot 9 is rotated to the top, the rotation of rotating base 12 drives the drive wheel 14 to rotate, which in turn drives the driven ring 16 to rotate via the transmission belt 15. This, in turn, drives rotating base 2 11 to rotate via the bending rod 18, thereby rotating the corresponding positioning screen 10 directly below the projection lamp 19. This allows for the positioning of circuit boards of different sizes to be tested. Magnets 13 and 2 can fix the rotating handle 8 when it is rotated, thus fixing the position of rotating base 12 and preventing it from rotating during use. The support legs 6 can support the entire device, ensuring its normal operation.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
