Technical Field

[0001] This utility model relates to the field of temperature and frequency instrument testing technology, specifically to a driver board testing fixture. Background Technology

[0002] A thermotherapy device is a physiotherapy device that combines thermotherapy with microcurrent stimulation. It is mainly used to promote blood circulation, relieve pain and muscle fatigue, and is commonly used in home health care or rehabilitation physiotherapy settings.

[0003] The driver board is the control center of the temperature transmitter, mainly responsible for controlling and regulating the temperature control system and ultrasonic operation. Existing driver board testing fixtures (application number 202420397812.3) use a fixing mechanism on the test bench to fix and test the driver board. However, during testing of the driver board on the test bench, due to its large structure, a single fixing mechanism can only fix it, not precisely position it to ensure the various detection points on the driver board are connected to the corresponding probes, thus affecting the accuracy of the driver board testing fixture. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a driver board testing fixture to solve the technical problem that the existing driver board testing fixture cannot accurately position the driver board during testing so that each detection point on the driver board is positioned and connected with the corresponding probe, which affects the testing accuracy of the driver board testing fixture.

[0005] According to the technical solution provided in the embodiments of this application, the driver board testing fixture includes a test platform, on which two slide grooves are provided, and corresponding fasteners are slidably installed in each slide groove so that the two corresponding fasteners fix the carrier board.

[0006] Two positioning slots are arranged side by side and correspondingly on both sides of the carrier plate, and are engaged with the corresponding fastener support, so that the carrier plate is positioned and engaged on the fastener.

[0007] Several positioning holes are evenly arranged around the positioning groove on the carrier plate, and several corresponding positioning protrusions are provided on the test platform. Each positioning protrusion is positioned and engaged in the corresponding positioning hole, thereby positioning the installation position of the carrier plate.

[0008] The positioning groove is disposed on the surface of the carrier plate and its structure is similar to that of the bottom structure of the drive plate, so that the drive plate is positioned and engaged in the positioning groove.

[0009] Furthermore, the positioning slot has a U-shaped structure.

[0010] Furthermore, the positioning groove on the carrier plate is provided with a number of detection holes, each of which corresponds to a detection point on the drive plate.

[0011] Furthermore, the test bench is also equipped with several probes, each probe corresponding to one of the detection holes.

[0012] Furthermore, the carrier plate is provided with a number of screw holes, and a corresponding fixing bolt is screwed into each screw hole so that the fixing bolt rotates and moves downward, thereby fixing the drive plate on the carrier plate.

[0013] Furthermore, the test bench is also equipped with two start buttons and two indicator lights, with the two start buttons being electrically connected to the corresponding probes and indicator lights, respectively.

[0014] Furthermore, the test bench is also equipped with an ultrasonic interface, which is connected to the ultrasonic connection terminal on the driver board for ultrasonic output testing on the driver board.

[0015] Furthermore, both the latching component and the carrier plate are made of insulating material, so that during the testing process on the test bench, the operator is less likely to come into contact with the current, thereby improving the safety of the test fixture.

[0016] In summary, the beneficial effects of this application are as follows:

[0017] 1. By setting corresponding positioning slots on both sides of the carrier plate, the corresponding positioning slots are engaged with the fasteners, thereby positioning both sides of the carrier plate, so that each test hole on the carrier plate is engaged with the corresponding probe on the test bench, thereby improving the testing accuracy of the test fixture.

[0018] Second, by setting several positioning holes on the carrier plate and setting several corresponding positioning protrusions on the test bench, so that each positioning hole is engaged with the corresponding positioning protrusion, the carrier plate is positioned and installed on the top of the test bench, so that the probe is positioned and abutted against the detection point on the drive plate engaged on the carrier plate, thereby improving the testing accuracy of the temperature and frequency meter drive board by the test fixture.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] The driver board test fixture has the following structure: Figures 1-4 As shown, the system includes a test platform 100, which has an L-shaped structure. The test platform 100 has two sliding grooves, each containing a corresponding fastener 110 for sliding installation. The two corresponding fasteners 110 secure the sides of the carrier plate 200 on which the drive board is placed. Two positioning slots 210 are arranged side-by-side and correspondingly on both sides of the carrier plate 200, engaging with the corresponding fastener 110 support portions. This positions the carrier plate 200 against the fasteners 110, preventing lateral movement of the carrier plate 200. Several positioning holes 220 are evenly distributed on the carrier plate 200. The positioning groove 230 is surrounded by a number of corresponding positioning protrusions 120 on the test platform 100. Each positioning protrusion 120 is positioned and engaged in the corresponding positioning hole 220, thereby positioning the installation position of the carrier plate 200, and thus positioning and abutting the probe 130 with the detection point on the drive plate that is engaged on the carrier plate 200, thereby improving the testing accuracy of the test fixture for the temperature and frequency instrument drive plate; the positioning groove 230 is set on the surface of the carrier plate 200, and its structure is similar to the bottom structure of the drive plate, so that the drive plate is positioned and engaged in the positioning groove 230, thereby positioning and installing each detection point on the drive plate at the corresponding detection hole 240.

[0028] As a preferred embodiment, please refer to Figure 3The positioning slot 210 has a U-shaped structure and is engaged with the support part on the buckle 110, thereby positioning the carrier plate 200 about the left and right to prevent the carrier plate 200 from moving during the test, which would cause inaccurate test results.

[0029] As a preferred embodiment, please refer to Figure 1 and Figure 3 The positioning groove 230 on the carrier plate 200 is also provided with a number of detection holes 240, each detection hole 240 corresponding to a detection point on the driver plate. The test stage 100 is also provided with a number of probes 130, each probe 130 corresponding to each detection hole 240. After the driver plate is positioned and engaged in the positioning groove 230, each probe 130 abuts against each detection point on the driver plate, thereby improving the accuracy of the test fixture in testing the driver plate.

[0030] As a preferred embodiment, please refer to Figure 1 and Figure 4 The carrier plate 200 is also provided with several screw holes 250, and each screw hole 250 is screwed with a corresponding fixing bolt, so that the fixing bolt rotates and moves down, thereby fixing the drive plate on the carrier plate 200.

[0031] As a preferred embodiment, please refer to Figure 1 and Figure 3 The test bench 100 is also equipped with two start buttons 140 and two indicator lights 150. The two start buttons 140 are electrically connected to the corresponding probes 130 and indicator lights 150, respectively. Pressing the start button 140 will power on the fan relay on the driver board. When the indicator light 150 connected to the start button 140 lights up, the driver board indicates that the fan relay is conducting normally. Then, pressing the other start button 140 will power on the long-wave relay connected to it. When the indicator light 150 connected to the start button 140 lights up, the driver board indicates that the long-wave relay is conducting normally.

[0032] As a preferred embodiment, please refer to Figure 1 and Figure 3 The test bench 100 is also equipped with an ultrasonic interface 160. The ultrasonic connection terminal on the driver board is then plugged into the ultrasonic interface 160 on the test bench 100 to test the ultrasonic output on the driver board. The ultrasonic display screen 170 on the test bench 100 displays the ultrasonic output, thereby improving the testing efficiency and quality of the driver board test fixture for the temperature and frequency instrument driver board.

[0033] As a preferred embodiment, please refer to Figure 3 and Figure 4Both the buckle 110 and the carrier plate 200 are made of insulating material so that the operator is less likely to come into contact with the current during the test of the drive board on the test bench 100, thereby improving the safety of the test fixture.

[0034] The working principle of this utility model driver board testing fixture is as follows:

[0035] During the testing of the temperature transmitter driver board using the driver board testing fixture, the tester snaps the insulating carrier plate 200 between two clips 110. Corresponding positioning slots 210 are provided on both sides of the carrier plate 200, allowing the two positioning slots 210 to engage with the corresponding clips 110, thus positioning the sides of the carrier plate 200. Several positioning holes 220 are provided on the carrier plate 200, and several corresponding positioning protrusions 120 are provided on the test bench 100, allowing each positioning hole 220 to engage with its corresponding positioning protrusion 120. This positions the carrier plate 200 on the top of the test bench 100, positioning and engaging the test holes on the carrier plate 200 with the corresponding probes 130 on the test bench 100. The driver board is positioned and engaged within the positioning slots 230 on the carrier plate 200, thus positioning and engaging the probes 130 with the detection points on the driver board attached to the carrier plate 200, thereby improving the accuracy of the test fixture. To ensure the accuracy of the temperature and frequency analyzer driver board test, after the driver board is installed, the fixing bolts are screwed into the corresponding screw holes 250 to fix the driver board around its perimeter. The tester presses the start button 140 to power on the fan relay on the driver board. When the indicator light 150 connected to the start button 140 illuminates, the driver board indicates that the fan relay is conducting normally. Then, another start button 140 is pressed to power on the long-wave relay connected to the start button 140. When the indicator light 150 connected to the start button 140 illuminates, the long-wave relay on the driver board is conducting normally. Then, the ultrasonic connection terminal on the driver board is plugged into the ultrasonic interface 160 on the test bench 100 to test the ultrasonic output on the driver board. The ultrasonic display screen 170 on the test bench 100 displays the ultrasonic output, thereby improving the testing efficiency and quality of the temperature and frequency analyzer driver board using the driver board testing fixture.
