Description

Technical Field

[0001] This utility model relates to the field of semiconductor technology, specifically to a motor mounting structure for a packaging and testing machine. Background Technology

[0002] In the packaging test equipment of the vector network analyzer, the motor is the key actuator. Its main function is to drive the test probe, robotic arm or other moving parts to achieve precise positioning and contact with the device under test, thereby ensuring the accuracy and reliability of the test. As modern electronic devices develop towards miniaturization, high frequency and integration, the performance requirements of the motor of the packaging test equipment are also getting higher and higher.

[0003] Currently, the effective detection rate of packaging and testing machines on the market is low in actual use. This is mainly because the nozzle rod of the motor in the packaging and testing machine is not collinear with the center line of the motor shaft. Traditional bracket connectors have large installation errors, which leads to a reduction in the effective detection rate of the device. Therefore, a motor mounting structure for packaging and testing machines has been designed to solve the above problems. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a motor mounting structure for a packaging test machine to solve the technical problem of low effective detection rate of traditional devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a motor mounting structure for a packaging test machine, comprising a main body, on which a linear motor is mounted, and a motor shaft is provided at the bottom end of the linear motor. A bracket connector is mounted on the top of the main body, and screw connection holes and pin holes are provided at the connection between the bracket connector and the main body. Both screw connection holes and pin holes are designed as slotted holes.

[0006] By adopting the above technical solution, the screw connection holes and pin holes of the waist hole design allow for fine-tuning during installation, ensuring that the nozzle of the rod head is collinear with the center line of the motor shaft, thereby improving the detection accuracy and yield. Compared with the traditional round hole design, the waist hole provides a larger adjustment range and reduces the performance degradation of the device caused by installation errors.

[0007] The present invention is further configured such that a rotating shaft is provided outside the main body, and a plurality of limiting rods are connected to the rotating shaft. A rod head suction nozzle is installed at the end of each limiting rod, and a return spring is connected between each rod head suction nozzle and the corresponding limiting rod. The rod head suction nozzle cooperates with the motor shaft.

[0008] By adopting the above technical solution, multiple nozzle heads can simultaneously contact and test multiple devices under test, improving testing efficiency. In addition, the design of the return spring ensures that the force applied by each nozzle head is uniform, reducing testing errors caused by uneven force.

[0009] The present invention is further configured such that a mesh separation detection platform is installed below the main body, and the detection platform of the mesh separation detection platform cooperates with the corresponding rod head suction nozzle.

[0010] By adopting the above technical solution, as the rotating shaft rotates, the nozzle on the limit rod moves sequentially to the motor shaft of the linear motor. As the motor shaft descends, the device to be tested is pushed onto the mesh detection platform, thereby completing the detection of the device to be tested.

[0011] In summary, the present invention has the following main advantages:

[0012] This invention utilizes a waist-shaped design for the screw connection holes and pin holes, allowing for fine-tuning during the installation of the bracket connector. This ensures that the nozzle rod head is collinear with the center line of the motor shaft, thereby improving detection accuracy and yield. Compared to the traditional round hole design, the waist-shaped holes provide a larger adjustment range, reducing performance degradation caused by installation errors. The waist-shaped design of the screw connection holes and pin holes not only enhances the maintainability and adaptability of the equipment but also reduces incorrect assembly and equipment wear, thus extending the service life of the equipment.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] The embodiments of this utility model will be described below based on its overall structure.

[0020] The motor mounting structure of the packaging and testing machine, such as... Figure 1-4 As shown, the device includes a main body 1, on which a linear motor 4 is mounted, and a motor shaft 5 is provided at the bottom of the linear motor 4. A bracket connector 2 is mounted on the top of the main body 1, and the connection between the bracket connector 2 and the main body 1 is provided with screw connection holes 3 and pin holes 11. Both screw connection holes 3 and pin holes 11 are designed as slotted holes. The slotted hole design of the screw connection holes 3 and pin holes 11 allows for fine adjustment during installation to ensure that the rod head nozzle 6 is collinear with the center line of the motor shaft 5, thereby improving detection accuracy and yield. Compared with the traditional round hole design, the slotted hole provides a larger adjustment range and reduces the performance degradation of the device caused by installation errors.

[0021] The main body 1 is provided with a rotating shaft 10, and several limiting rods 9 are connected to the rotating shaft 10. Each limiting rod 9 has a rod head suction nozzle 6 installed at its end, and each rod head suction nozzle 6 is connected to the corresponding limiting rod 9 with a return spring 7. The rod head suction nozzle 6 cooperates with the motor shaft 5. Multiple rod head suction nozzles 6 can simultaneously contact and test multiple devices under test, improving testing efficiency. In addition, the design of the return spring 7 ensures that the force applied by each rod head suction nozzle 6 is uniform, reducing testing errors caused by uneven force.

[0022] A mesh detection platform 8 is installed below the main body 1, and the detection platform of the mesh detection platform 8 is matched with the corresponding rod head suction nozzle 6. As the rotating shaft 10 rotates, the rod head suction nozzle 6 on the limiting rod 9 moves sequentially to the motor shaft 5 of the linear motor 4. As the motor shaft 5 descends, the device to be tested is pushed onto the mesh detection platform 8, thereby completing the detection of the device to be tested.

[0023] Working principle: The main body 1 is equipped with a bracket connector 2, in which the screw connection hole 3 and pin hole 11 with the waist hole design allow for fine adjustment during installation to ensure that the rod head suction nozzle 6 is collinear with the center line of the motor shaft 5, thereby improving the detection accuracy and yield. Compared with the traditional round hole design, the waist hole provides a larger adjustment range and reduces the performance degradation of the device caused by installation errors. At this time, as the rotating shaft 10 rotates, the rod head suction nozzle 6 on the limit rod 9 moves sequentially to the motor shaft 5 of the linear motor 4. As the motor shaft 5 descends, the device to be tested is pushed onto the mesh detection platform 8, thereby completing the detection of the device. In addition, the design of the return spring 7 ensures that the force applied to each rod head suction nozzle 6 is uniform, reducing the test error caused by uneven force.
