Abstract
Description
Technical Field
[0001] This application relates to the field of electric vehicle controllers, and more particularly to a wave soldering plug testing device for electric vehicle controllers. Background Technology
[0002] An electric vehicle controller is a core component used to control the starting, running, forward and reverse movement, speed, and stopping of the electric vehicle motor, as well as other electronic devices in the vehicle. The controller consists of a circuit board, which undergoes wave soldering after production. Following this, the soldering of the component pins on the circuit board is inspected. If any component pins are missing or poorly soldered, the components on the circuit board are prone to loosening or breaking contacts during later use, affecting their lifespan.
[0003] In existing technologies, the soldering of components on circuit boards is usually inspected by direct human observation. However, the pins of components on circuit boards are usually quite small, making it inconvenient for human eyes to observe and inspect. Prolonged observation can easily cause eye fatigue and errors, affecting the convenience and accuracy of the inspection. Utility Model Content

[0016] Preferably, the elastic element is a spring, one end of which is fixedly connected to the support frame and the other end is fixedly connected to the cylinder.
[0017] By adopting the above technical solution, the support frame can provide installation for the cylinder, and the spring can apply a thrust to the cylinder, thereby providing space for the rotation of the cylinder; when the circuit board is detected to be improperly soldered, the piston rod of the cylinder drives the movement of the push block, so that the push block abuts against one side of the circuit board. At this time, both the push block and the cylinder rotate, thereby raising one side of the circuit board, making it easier to remove the circuit board.
[0018] Preferably, the push block has an inclined surface, which contacts one side of the circuit board.

[0028] To make the inventive objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0029] The following is in conjunction with the appendix Figure 1-4This application will be described in further detail.
[0030] Example 1:
[0031] This application discloses an electric vehicle controller wave soldering plug-in testing device, such as... Figure 1 As shown, the system includes a frame 1, with a start button 12 and a stop button 13 mounted on one side. A conveyor belt 11 is mounted on the frame 1, supporting an array of circuit boards, with the circuit boards adhering to the edges of the conveyor belt 11. A mounting frame 2 is provided on the frame 1, with a camera 21 and a display screen 22 mounted on the mounting frame 2. When a circuit board needs testing, the conveyor belt 11 transports the circuit board. When the circuit board moves to the bottom of the mounting frame 2, the camera 21 takes a picture of the circuit board, and the display screen 22 displays the photograph, also inspecting the solder joints of the components.
[0032] like Figure 1 and 2 As shown, mounting bracket 2 is mounted on frame 1, and a positioning rod 23 is fixedly connected to mounting bracket 2. The length direction of positioning rod 23 is vertical. Positioning rod 23 is equipped with a positioning element, namely positioning bolt 24, which passes through positioning rod 23 and is threadedly connected to frame 1. When mounting bracket 2 needs to be installed, the operator can move mounting bracket 2, thereby moving positioning rod 23 to a suitable position and making it fit against one side of frame 1. Then, positioning bolt 24 is screwed in, causing positioning bolt 24 to rotate until it abuts against positioning rod 23. Positioning bolt 24 can limit positioning rod 23, thereby limiting mounting bracket 2, facilitating the installation of mounting bracket 2 and thus facilitating the testing of circuit boards.
[0033] The implementation principle of the wave soldering plug-in testing device for electric vehicle controllers in this application is as follows:
[0034] The operator moves the mounting bracket 2 to a suitable position on the frame 1, and uses the positioning rod 23 and positioning bolt 24 to move and fix the mounting bracket 2 to the appropriate position. Then, the circuit board is transported by the conveyor belt 11. When the circuit board moves to the bottom of the mounting bracket 2, the imaging device 21 can take a picture of the circuit board, and the display screen 22 can display the picture. The solder joints of the components are also inspected. If improper soldering is detected, the machine can be stopped, and the operator can remove the improperly soldered circuit board, which improves the convenience and accuracy of the inspection.
[0035] Example 2:
[0036] like Figure 3 and 4As shown, a push block 3 slides relative to the frame 1. The push block 3 is located on one side of the mounting bracket 2 along the direction of circuit board travel. The push block 3 has an inclined surface 31. The push block 3 can slide to abut against one side of the circuit board, at which point the inclined surface 31 contacts one side of the circuit board. When the circuit board is found to be improperly soldered, the push block 3 can apply force to one side of the circuit board, thereby raising one side of the circuit board, making it easier for the operator to remove the improperly soldered circuit board.
[0037] like Figure 3 and 4 As shown, the frame 1 is equipped with a control assembly 4 for controlling the sliding of the push block 3. The control assembly 4 includes a support frame 41, a cylinder 42, and an elastic element. The support frame 41 is fixedly installed on the frame 1 and is located on one side of the mounting frame 2 along the circuit board travel direction. The cylinder 42 is installed on the support frame 41 and is rotatably connected to the support frame 41. The push block 3 is rotatably connected to the piston rod of the cylinder 42. The elastic element is a spring 43. One end of the spring 43 is fixedly connected to the support frame 41, and the other end is fixedly connected to the cylinder 42. Under normal conditions, the spring 43 applies a thrust to the cylinder 42, causing the bottom end of the cylinder 42 to move away from the support frame 41. When a faulty soldering is detected on the circuit board, the conveyor belt 11 continues to move the circuit board, moving it out of the mounting bracket 2. At this time, the piston rod of the cylinder 42 can drive the push block 3 to move, so that the push block 3 abuts against one side of the circuit board. Both the push block 3 and the cylinder 42 rotate, thereby pushing one side of the circuit board upward, making it easier for the operator to remove the faulty soldering circuit board.
[0038] The implementation principle of the wave soldering plug-in testing device for electric vehicle controllers in this application is as follows:
[0039] When a circuit board is found to be improperly soldered, the conveyor belt 11 moves the circuit board to the bottom of the mounting bracket 2, and then the cylinder 42 moves the push block 3. The push block 3 can apply force to one side of the circuit board, raising one side of the circuit board so that the operator can know the location of the improperly soldered circuit board, thus facilitating the removal of the circuit board.
[0040] 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.
