Description

Technical Field

[0001] This application relates to the field of electronic component testing technology, and in particular to a resistor positioning platform. Background Technology

[0002] With the continuous improvement of mobile terminal functions, especially smartphones, the number and types of integrated electronic components are gradually increasing. Among them, surface mount resistors, as basic and critical components, are widely used in various circuit modules to achieve functions such as current control, voltage distribution, and signal conditioning. The performance stability of surface mount resistors is directly related to the reliability of the entire circuit. Therefore, in the mobile phone manufacturing process, accurate and effective testing of surface mount resistors has become an essential procedure.

[0003] In existing technologies, resistance testing typically involves fixing the resistor on a positioning platform and using a probe testing mechanism to collect resistance parameters. However, in real-world applications, mobile phone circuits often operate at high temperatures, causing the resistor's performance to deviate with temperature changes. Test results performed only at room temperature cannot fully reflect the resistor's stability under actual operating conditions. To verify the resistor's performance in high-temperature environments, existing methods usually simulate high-temperature conditions by heating the entire circuit and then performing the resistance test.

[0004] However, simulating high temperatures and testing resistance through overall heating can lead to unnecessary energy consumption and may also interfere with the testing environment of other testing procedures or surrounding components, thereby reducing the accuracy and stability of the test. Utility Model Content

[0005] To enable heating only the resistor under test after resistor positioning, avoiding heating the entire system and minimizing the impact on other testing procedures, this application provides a resistor positioning platform. This application provides the following technical solution:

[0006] A resistor positioning platform includes a base, a base plate, and a positioning plate. The base plate is disposed on the base, and the positioning plate is disposed on the base plate. The top surface of the positioning plate is provided with a positioning bearing for limiting the position of the resistor. The base plate is provided with a first positioning component and a second positioning component on adjacent sides of the positioning plate, respectively. A heating rod is inserted inside the positioning plate.

[0007] In one specific implementation, the base plate is provided with heat-insulating side plates around the positioning plate, the heat-insulating side plates are provided with a first clearance groove at the position of the first positioning component and the second positioning component, and the heat-insulating side plates are provided with a second clearance groove at the position of the heating rod.

[0008] In one specific implementation, a heat-insulating base plate is provided between the base plate and the positioning plate. The size of the heat-insulating base plate is the same as that of the positioning plate, and the inner wall of the heat-insulating side plate is in contact with the outer wall of the positioning plate and the heat-insulating base plate.

[0009] In one specific implementation, the first positioning component includes a first positioning cylinder and a first rotary bearing. The first positioning cylinder is disposed on the base plate, and the piston rod of the first positioning cylinder is connected to the first rotary bearing. The positioning plate is provided with a first positioning groove on one side of the first positioning cylinder, the piston rod of the first positioning cylinder is located in the first positioning groove, and the first rotary bearing is located above the first positioning groove.

[0010] In one specific implementation, the second positioning component includes a second positioning cylinder and a second rotary bearing. The second positioning cylinder is disposed on the base plate, and the piston rod of the second positioning cylinder is connected to the second rotary bearing. The positioning plate has a second positioning groove on one side of the second positioning cylinder, the piston rod of the second positioning cylinder is located in the second positioning groove, and the second rotary bearing is located above the second positioning groove.

[0011] In one specific implementation scheme, the positioning plate is provided with a plurality of suction holes, which are evenly distributed on the top surface of the positioning plate. The suction holes are used to connect with a vacuum generator used in conjunction with the resistance positioning platform.

[0012] In one specific implementation, the heating rods are provided in a plurality of form, and the plurality of heating rods are evenly arranged through the positioning plate, wherein a temperature sensor is provided inside the positioning plate.

[0013] In one specific implementation, a micrometer adjustment platform is provided between the base and the base plate.

[0014] In summary, the beneficial effects of this application include at least the following:

[0015] 1) By sequentially installing a heat-insulating base plate and a positioning plate on the base plate, and adding heat-insulating side plates around the positioning plate, a relatively independent and stable heating space can be formed for the resistor under test during the positioning process. This effectively prevents heat from diffusing outward and ensures the constancy and controllability of the heating environment. Simultaneously, heating rods are evenly inserted inside the positioning plate, and a temperature sensor is configured. This not only enables rapid and uniform heating of the resistor but also allows for real-time monitoring and adjustment of the heating temperature, ensuring the accuracy and reliability of resistor testing under different temperature conditions.

[0016] 2) The combination structure of the rotating bearing and the positioning groove reduces friction and damage during the clamping process, thereby improving the stability and reliability of the resistor during high-temperature testing.

[0017] A positioning bearing is installed on the top surface of the positioning plate to initially limit the resistor's position. A first positioning component and a second positioning component are installed on the base plate, and mechanical drive further supports and securely fixes the resistor at multiple points. Simultaneously, a heating rod is inserted inside the positioning plate to provide a controllable heating environment while the resistor is fixed, enabling testing of the resistor under different temperature conditions. By integrating the heating element inside the positioning plate and combining it with a multi-point mechanical limiting structure, the resistor can achieve precise positioning and localized heating during testing, thus ensuring the accuracy and stability of the test while avoiding unnecessary impact on surrounding components or other testing procedures.

[0026] This application discloses a resistor positioning platform.

[0027] Reference Figure 1 The resistance positioning platform includes a base 1, a micrometer adjustment platform 2, a base plate 3, and a positioning plate 5. The micrometer adjustment platform 2 is mounted on the base 1, and the base plate 3 is mounted on the micrometer adjustment platform 2. Figure 2The base plate 3 has a heat-insulating base plate 9 on its top surface, and a positioning plate 5 is installed on the heat-insulating base plate 9. The dimensions of the heat-insulating base plate 9 and the positioning plate 5 are the same. Heat-insulating side plates 4 are provided around the positioning plate 5 on the base plate 3. The inner side wall of the heat-insulating side plates 4 is in contact with the outer side wall of the positioning plate 5 and the heat-insulating base plate 9. Several heating rods 8 are inserted into the positioning plate 5, and the heating rods 8 are evenly arranged in the positioning plate 5. A temperature sensor is installed in the positioning plate 5. The heat-insulating side plates 4 have a second clearance groove 42 at the position of the heating rods 8 to facilitate the setting of the heating rods 8 for power supply. By sequentially setting the heat-insulating base plate 9 and the positioning plate 5 on the base plate 3, and adding heat-insulating side plates 4 around the positioning plate 5, the measured resistor can form a relatively independent and stable heating space during the positioning process, thereby effectively preventing heat from diffusing outward and ensuring the constantness and controllability of the heating environment. Meanwhile, heating rods 8 are evenly inserted inside the positioning plate 5 and a temperature sensor is configured, which not only enables rapid and uniform heating of the resistor, but also allows for real-time monitoring and adjustment of the heating temperature to ensure the accuracy and reliability of resistor testing under different temperature conditions.

[0028] Reference Figure 1 and Figure 2 The positioning plate 5 is provided with positioning bearings 52 for limiting the resistor. There are three positioning bearings 52, one of which is located on one side of the top surface of the positioning plate 5, and the other two are located on the opposite side of the top surface of the positioning plate 5. The base plate 3 is provided with a first positioning component 6 and a second positioning component 7 on the adjacent sides of the positioning plate 5 where the positioning bearings 52 are not located. The heat insulation side plate 4 is provided with a first clearance groove 41 at the position of the first positioning component 6 and the second positioning component 7.

[0029] Reference Figure 1 and Figure 2The first positioning assembly 6 includes a first positioning cylinder 61 and a first rotary bearing 62. The first positioning cylinder 61 is fixedly installed on the top surface of the base plate 3. The piston rod of the first positioning cylinder 61 is fixedly connected to the first rotary bearing 62. The positioning plate 5 has a first positioning groove 53 on one side of the first positioning cylinder 61. The piston rod of the first positioning cylinder 61 passes through the first clearance groove 41 and is located in the first positioning groove 53. The first rotary bearing 62 is located above the first positioning groove 53. The second positioning assembly 7 includes a second positioning cylinder 71 and a second rotary bearing 72. The second positioning cylinder 71 is fixedly installed on the top surface of the base plate 3. The piston rod of the second positioning cylinder 71 is fixedly connected to the second rotary bearing 72. The positioning plate 5 has a second positioning groove 54 on one side of the second positioning cylinder 71. The piston rod of the second positioning cylinder 71 passes through the first clearance groove 41 and is located in the second positioning groove 54. The second rotary bearing 72 is located above the second positioning groove 54. During the resistor positioning process, the resistor is first placed between the positioning bearings 52 on the top surface of the positioning plate 5. The three positioning bearings 52 provide initial positioning for the resistor, preventing large-scale horizontal displacement. Subsequently, the first positioning component 6 and the second positioning component 7, driven by the first positioning cylinder 61 and the second positioning cylinder 71 respectively, cause their piston rods to push the rotary bearings along the first positioning groove 53 and the second positioning groove 54. The rotary bearings further press and limit the resistor, thereby achieving multi-point support and stable fixation of the resistor. Through the above structure, the resistor is reliably limited in both the longitudinal and lateral directions, ensuring that the resistor's position remains consistent during the testing process. In addition, the cooperative structure between the rotary bearings and the positioning grooves reduces friction and damage to the resistor during clamping, thereby improving the stability and reliability of the resistor during high-temperature testing.

[0030] Reference Figure 2 The positioning plate 5 has several suction holes 51 evenly distributed on its top surface. These suction holes 51 connect to a vacuum generator used in conjunction with the resistor positioning platform. During positioning, once the resistor is placed on the top surface of the positioning plate 5, the vacuum generator connects with the suction holes 51, creating a negative pressure adsorption force on the top surface of the positioning plate 5, thus firmly adsorbing the resistor onto the positioning plate 5. Because the suction holes 51 are evenly distributed on the top surface of the positioning plate 5, the adsorption force can act on different positions of the resistor, ensuring that the resistor maintains a stable and uniform stress state when fixed, avoiding tilting or displacement problems caused by single-point adsorption. The combination of these suction holes 51 and the vacuum generator not only further enhances the positioning stability of the resistor but also forms a double fixing effect with the mechanical limiting structure, improving positioning accuracy while reducing the risk of loosening of the resistor due to vibration or temperature changes during testing.

[0031] In summary, by setting a heat-insulating base plate 9 and a heat-insulating side plate 4 between the positioning plate 5 and the base plate 3, a relatively independent and stable heating space is formed. Heating rods 8 and temperature sensors are evenly distributed within the positioning plate 5 to achieve rapid heating and real-time temperature monitoring of the resistor. Simultaneously, combined with the positioning bearing 52, the cylinder-driven rotary bearing positioning assembly, and the vacuum adsorption hole, the resistor can be dually fixed by multi-point limiting and negative pressure adsorption during testing, ensuring its stable position even at high temperatures. Compared with existing overall heating methods, the solution in this application only heats the resistor locally, significantly reducing energy consumption and avoiding interference with other testing processes or surrounding components, thus effectively solving the problems of insufficient testing accuracy and stability in existing technologies.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
