Description

Technical Field

[0001] This utility model belongs to the field of circuit testing technology, and specifically relates to an integrated circuit testing device. Background Technology

[0002] Integrated circuits (ICs) are created by integrating multiple electronic components (such as transistors, resistors, and capacitors) onto a single chip using semiconductor technology, forming a complex circuit system. They are widely used in computers, communications, home appliances, automobiles, and other fields, and have advantages such as small size, high performance, low cost, and high reliability. The invention of ICs has driven the development of electronic technology and made them a core component of modern electronic products and information technology.

[0003] Chinese patent publication number CN219997245U discloses an integrated circuit testing device, including a base. Two sets of servo motors are fixedly installed on one side of the base, and bidirectional threaded rods are fixedly connected to the output shafts of the two sets of servo motors. When positioning an integrated circuit board, this device first places the integrated circuit board on the upper surface of a placement plate, then starts the servo motors, which drive the bidirectional threaded rods to rotate. This structure effectively avoids the problem of circuit board misalignment during testing, achieving the desired positioning effect. It also improves the practicality of the device, enabling it to test circuit boards of different specifications, reducing positioning time, increasing testing efficiency, preventing damage to the integrated circuit board during actual use, and improving the accuracy of test results.

[0004] However, the current testing device has the following problem: when clamping and positioning the integrated circuit board, excessive clamping force can damage the integrated circuit board. Therefore, we propose an integrated circuit testing device. Utility Model Content

[0005] The purpose of this invention is to provide an integrated circuit testing device that can solve the problem in related technologies of avoiding damage to integrated circuit boards caused by excessive clamping force when clamping and positioning them.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An integrated circuit testing device includes a base plate, an L-shaped support frame fixedly connected to the top of the base plate, a detection component for testing disposed on the top of the L-shaped support frame, a driving component disposed on the top of the base plate, a connecting rod fixedly connected to the moving end of the driving component, and a clamping plate fixedly connected to the end of the connecting rod away from the driving component. The device is characterized in that: an anti-damage device is disposed on the side of the clamping plate, the anti-damage device including a short rod, the outer wall of the short rod penetrating and sliding on the side of the clamping plate, a push plate fixedly connected to one end of the short rod, a spring disposed between the clamping plate and the push plate, a friction plate fixedly connected to the top of the base plate, a hinge plate hinged to the side of the push plate, and a friction block hinged to the side of the hinge plate away from the push plate.

[0008] The side surface of the friction block is rough, the side surface of the friction plate is rough, and the rough surface of the friction plate is located on the displacement trajectory of the rough surface of the friction block.

[0009] The drive assembly includes a fixed frame, a motor is fixedly connected to the inner wall of the fixed frame, a bidirectional threaded rod is fixedly connected to the output shaft of the motor, and two threaded sleeves are threadedly connected to the circumferential surfaces of the bidirectional threaded rod with opposite thread directions, and the two threaded sleeves are provided as movable ends.

[0010] The bottom of the inner wall of the push plate is provided with an anti-wear device, which includes two rotating shafts. The bottom of the two rotating shafts is rotatably connected to the bottom of the inner wall of the push plate. A rubber belt is connected between the two rotating shafts. A rotating wheel is fixedly connected to the top of one of the rotating shafts. A one-way bearing is fixedly connected to the top of the rotating wheel. A thin plate is fixedly connected to the bottom of the inner wall of the push plate. An L-shaped plate is fixedly connected to the top of the friction plate.

[0011] The outer wall of the rotating wheel is roughened, the side of the L-shaped plate is roughened, and the roughened surface of the rotating wheel is in contact with the roughened surface of the L-shaped plate.

[0012] The inner wall of the thin plate is in contact with the inner wall of the rubber belt.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This invention utilizes a combination of a short rod, a push plate, a spring, a hinge plate, a friction block, and a friction plate to stop the push plate from moving. As the clamping plate continues to move, the push plate pushes the friction block towards the friction plate via the hinge plate. When the rough surface of the friction block comes into contact with the rough surface of the friction plate, the resistance between the friction block and the friction plate increases. This increased resistance makes it difficult for the clamping plate to continue moving, thus avoiding damage to the integrated circuit board due to excessive clamping force.

[0015] This invention utilizes the combination of a rotating shaft, rubber belt, rotating wheel, one-way bearing, L-shaped plate, and thin plate. The rotating wheel is restricted by the one-way bearing, so it does not drive the rubber belt to rotate via the rotating shaft. Therefore, the rotating wheel and the L-shaped plate are in a slipping state. This process repeats, and the rubber belt rotates each time the push plate moves, ensuring that the clamping surface of the rubber belt is different each time, thus avoiding the problem of the rubber belt being damaged by being clamped on the same side.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figure 1-5As shown, an integrated circuit testing device includes a base plate 1. An L-shaped support frame 2 is fixedly connected to the top of the base plate 1. A detection component 201 for testing is disposed on the top of the L-shaped support frame 2. A drive component 3 is disposed on the top of the base plate 1. The drive component 3 includes a fixed frame 31. A motor 32 is fixedly connected to the inner wall of the fixed frame 31. A bidirectional threaded rod 33 is fixedly connected to the output shaft of the motor 32. Two threaded sleeves 34 are threadedly connected to the circumferential surfaces of the bidirectional threaded rod 33 with opposite thread directions. The two threaded sleeves 34 are provided as moving ends. A connecting rod 4 is fixedly connected to the moving end of the drive component 3. The end of the connecting rod 4 away from the drive component 3 is fixedly connected to... A clamping plate 401 is characterized in that: a damage prevention device 5 is provided on the side of the clamping plate 401, the damage prevention device 5 includes a short rod 51, the outer wall of the short rod 51 penetrates and slides on the side of the clamping plate 401, a push plate 52 is fixedly connected to one end of the short rod 51, a spring 53 is provided between the clamping plate 401 and the push plate 52, a friction plate 56 is fixedly connected to the top of the bottom plate 1, a hinge plate 54 is hinged to the side of the push plate 52, a friction block 55 is hinged to the side of the hinge plate 54 away from the push plate 52, the side of the friction block 55 is a rough surface, the side of the friction plate 56 is a rough surface, and the rough surface of the friction plate 56 is located on the displacement trajectory of the rough surface of the friction block 55.

[0025] According to the above structure, the integrated circuit board is placed on the base plate 1, and the motor 32 is started. The output shaft of the motor 32 causes the bidirectional threaded rod 33 to rotate. The rotation of the bidirectional threaded rod 33 causes the two threaded sleeves 34 to move towards the integrated circuit board. The movement of the two threaded sleeves 34 drives the connecting rod 4 to move. The movement of the connecting rod 4 causes the clamping plate 401 to fix the integrated circuit board. Then, the detection component 201 is started to detect the integrated circuit board. The movement of the clamping plate 401 drives the short rod 51 to move. The movement of the short rod 51 drives the push plate 52. When the push plate 52 moves, it will first come into contact with the integrated circuit board. Under the reaction force of the integrated circuit board, the push plate 52 will stop moving. As the clamping plate 401 continues to move, the push plate 52 will push the friction block 55 towards the friction plate 56 through the hinge plate 54. When the rough surface of the friction block 55 comes into contact with the rough surface of the friction plate 56, the resistance between the friction block 55 and the friction plate 56 increases. The increase in resistance makes it difficult for the clamping plate 401 to continue moving, thereby avoiding the problem of damage to the integrated circuit board due to excessive clamping force.

[0026] like Figure 1-5As shown, an anti-wear device 6 is provided at the bottom of the inner wall of the push plate 52. The anti-wear device 6 includes two rotating shafts 61. The bottom of both rotating shafts 61 is rotatably connected to the bottom of the inner wall of the push plate 52. A rubber belt 62 is connected between the two rotating shafts 61. A rotating wheel 63 is fixedly connected to the top of one of the rotating shafts 61. A one-way bearing 64 is fixedly connected to the top of the rotating wheel 63. A thin plate 66 is fixedly connected to the bottom of the inner wall of the push plate 52. An L-shaped plate 65 is fixedly connected to the top of the friction plate 56. The outer wall of the rotating wheel 63 is rough, and the side of the L-shaped plate 65 is rough. The rough surface of the rotating wheel 63 is in contact with the rough surface of the L-shaped plate 65. The inner wall of the thin plate 66 is in contact with the inner wall of the rubber belt 62.

[0027] According to the above structure, during each clamping process of the integrated circuit board by the push plate 52, the push plate 52 drives the rotating shaft 61 to move synchronously. The movement of the rotating shaft 61 drives the rotating wheel 63 to move. Under the action of friction between the rough surface of the rotating wheel 63 and the rough surface of the L-shaped plate 65, the rotating wheel 63 drives one of the rotating shafts 61 to rotate. When the rotating shaft 61 rotates, it will cause the other rotating shaft 61 to rotate synchronously through the rubber belt 62. Each time the push plate 52 opens, the push plate 52 drives the rotating wheel 63 to move synchronously in the opposite direction through the rotating shaft 61. Since the rotating wheel 63 is restricted by the one-way bearing 64, the rotating wheel 63 will not drive the rubber belt 62 to rotate through the rotating shaft 61. Therefore, the rotating wheel 63 and the L-shaped plate 65 are in a slipping state at this time. This process is repeated, and each time the push plate 52 moves, it will cause the rubber belt 62 to rotate, thereby ensuring that the clamping surface of the rubber belt 62 is different each time, thus avoiding the problem of the rubber belt 62 being damaged by clamping the same surface all the time.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
