Description

Technical Field

[0001] This application relates to the technical field of auxiliary equipment for motor manufacturing, and particularly to a tool for testing motor circuit boards to improve efficiency. Background Art

[0002] With the development and progress of electronic technology, some finished motors are usually provided with circuit boards that can enhance the protection function of the motor.

[0003] During the motor production process, before installing the circuit board on the motor, it is necessary to test the circuit board. Workers usually use the probe of a multimeter to contact the test points on the circuit board, and determine whether the function of the circuit board is normal by observing the readings of the multimeter.

[0004] However, since the sizes of the test points on the circuit board are generally small, it is not convenient for workers to find the test points, resulting in low test efficiency of the circuit board. Moreover, due to human factors, misjudgment is likely to occur. Utility Model Content

[0005] In order to improve the test efficiency of the circuit board, this application provides a tool for testing motor circuit boards to improve efficiency.

The probe is electrically connected to the industrial control computer, and the position of the probe corresponds to the test points on the circuit board. A positioning component for positioning the circuit board is arranged below the probe.

[0008] By adopting the above technical solutions, during the circuit board testing process, the circuit board is placed on the positioning component, and the positioning component positions the circuit board. The moving component drives the probe to approach the circuit board. After the probe contacts the test points on the circuit board, an electrical connection between the circuit board and the industrial control computer is achieved, so that the parameters of the circuit board can be tested.

The connecting portion is disposed on one side of the mounting portion along a direction parallel to the mounting portion. The contact pin is mounted on the mounting portion, and the sliding hole is located on the connecting portion.

[0012] By adopting the above technical solution, the contact pin and the sliding hole are respectively arranged on two components, reducing the occurrence of mutual influence between the two.

[0013] Optionally, the moving component further includes a guide sleeve. The guide sleeve is slidably sleeved on the guide rod and fixedly connected to the sliding plate.

[0014] By adopting the above technical solution, the contact area between the sliding plate and the guide rod is increased through the sliding sleeve, thereby improving the stability of the sliding plate during the sliding process.

[0015] Optionally, multiple groups of the guide rods are arranged at intervals along a direction perpendicular to their own lengths.

[0016] By adopting the above technical solution, the arrangement of multiple guide rods further improves the stability of the sliding plate during the sliding process.

The driving member is arranged directly above the mounting portion, making the force more uniform when the driving member drives the sliding plate to press down, reducing the occurrence of the sliding plate tilting.

[0019] Optionally, the positioning component includes a positioning plate. The positioning plate is mounted on the cabinet, and a positioning groove for limiting the circuit board is provided on one side of the positioning plate close to the sliding plate.

[0020] By adopting the above technical solution, during the circuit board testing process, the circuit board is embedded in the positioning groove, and the positioning groove can limit the movement of the circuit board, thereby improving the stability of the circuit board during the testing process.

The contact component 2 includes a contact pin 21 and a moving component 22 for driving the contact pin 21 to move up and down. The contact pin 21 is vertically arranged and connected to the moving component 22. The upper end of the contact pin 21 is electrically connected to the industrial computer, and the industrial computer is used to test parameters (such as power, voltage, current, etc.) at the measuring point position on the circuit board. A positioning component 3 for positioning the circuit board is arranged below the contact pin 21. During the circuit board testing process, the circuit board is placed on the positioning component 3, and then the moving component 22 drives the contact pin 21 to abut against the measuring point on the circuit board, realizing the electrical connection between the circuit board and the industrial computer. Then, the test program inside the industrial computer is run to realize the rapid testing of the circuit board and improve the testing efficiency of the circuit board.

[0030] Referring to Figure 1 and Figure 2 , further, a motor electrically connected to the contact pin 21 can be arranged inside the cabinet 1. When the sliding plate 222 moves down, the motor is connected to the output end of the circuit board, so as to conveniently measure the parameters of the circuit board in the load state.

[0031] Referring to Figure 1 and Figure 2 , the moving component 22 includes a guide rod 221 and a sliding plate 222. The guide rod 221 is vertically arranged. A sliding hole is formed in the sliding plate 222, and the sliding plate 222 is slidably sleeved outside the guide rod 221. The touch pin 21 is installed on the sliding plate 222, and sliding the sliding plate 222 can drive the touch pin 21 to move.

[0032] Referring to Figure 1 and Figure 2 , the sliding plate 222 includes a mounting portion 2221 and a connecting portion 2222. The connecting portion 2222 is arranged on one side of the mounting portion 2221 in a direction parallel to the mounting portion 2221 and is integrally formed with the mounting portion 2221. The sliding hole is located on the connecting portion 2222. The staff can place the circuit board from the side of the sliding plate 222 away from the connecting portion 2222, reducing the influence caused by the guide rod 221 during the placement of the circuit board.

[0033] Referring to Figure 1 and Figure 2 , the moving component 22 further includes a guide sleeve 224. The guide sleeve 224 is slidably sleeved on the guide rod 221 and is welded to the connecting portion 2222 to improve the stability of the sliding plate 222 during sliding.

A positioning groove 32 is formed on the side of the positioning plate 31 close to the contact pin 21. The positioning groove 32 matches the shape of the circuit board, and the circuit board of the motor can be embedded in the positioning groove 32, thereby limiting the circuit board and reducing the movement of the circuit board during the circuit board testing process, and improving the stability during the circuit board testing process.
