Description

Technical Field

[0001] This utility model relates to the field of stepper driver side-view technology, and in particular to a centralized testing device for stepper drivers. Background Technology

[0002] A stepper driver is an actuator that converts electrical pulses into angular displacement. When a stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle in a set direction, rotating step by step at fixed angles. The amount of angular displacement can be controlled by controlling the number of pulses, thereby achieving accurate positioning; at the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency, thereby achieving speed regulation and positioning.

[0003] To test the performance of stepper drivers after manufacturing, they need to be tested. Traditional testing methods involve manual testing of each driver individually, which is time-consuming, labor-intensive, and inefficient. Furthermore, the lack of a mechanism to stabilize the stepper driver during testing leads to instability. Therefore, this invention provides a centralized testing device for stepper drivers to solve these technical problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the background art by proposing a centralized testing device for stepper drivers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A centralized testing device for stepper drivers includes:

[0007] A right-angle bracket and a test motor fixedly installed inside the right-angle bracket, with a controller fixedly installed on the outside of the right-angle bracket;

[0008] A fixing plate is fixedly installed on the top of the right-angle base. Multiple stepper driver bodies are inserted into the top of the fixing plate, and sensors are fixedly installed on the side of the fixing plate.

[0009] The clamping assembly includes two brackets fixedly mounted on the side of a fixed plate. A rotating shaft is rotatably mounted between the two brackets. A gear is fixedly mounted on the surface of the rotating shaft, and multiple pressure rods are fixedly mounted on the surface of the rotating shaft. The multiple pressure rods are all fixedly positioned directly above the corresponding stepper driver body. A screw is threaded through the top of the fixed plate. Multiple discs are fixedly mounted on a section of the screw above the fixed plate, and the multiple discs mesh with the gear.

[0010] Preferably, the top of the fixing plate is provided with multiple positioning slots, and the positioning slots are matched with the stepper driver body. Multiple circuit boards are fixedly installed in each positioning slot, and multiple conductive sheets are installed on the surface of each circuit board. The conductive sheets are electrically connected to the corresponding stepper driver body.

[0011] Preferably, a knob is fixedly installed at the bottom of the screw.

[0012] Preferably, the surface of the controller is equipped with a touch screen and multiple buttons, and the multiple buttons correspond one-to-one with multiple stepper driver bodies.

[0013] Preferably, the controller is equipped with indicator lights and a buzzer.

[0014] Compared with existing technologies, the advantages of the stepper driver centralized testing device provided by this utility model are as follows:

[0015] 1. By turning the screw through the knob, each disc spirals downward. At this time, the disc can rotate downward through the gear and the shaft to drive each pressure rod to flip down simultaneously until it presses the top of each stepper driver body, thus fixing it in the corresponding positioning groove, thereby completing the fixation of the stepper driver body and ensuring the stability of the stepper driver body during the test.

[0016] 2. Issue specified commands through the touch screen to control the test motor to react using the corresponding stepper driver body. That is, each stepper driver body can be tested independently. Then repeat the above operation by pressing different buttons to achieve the effect of centralized testing of multiple stepper driver bodies.

[0017] In summary, this invention, by rotating the screw, allows each pressure rod to flip downwards, pressing and fixing each stepper driver body onto the fixed plate, ensuring the stability of the stepper driver body during testing. Furthermore, by pressing different buttons and operating the touchscreen display, each stepper driver body can be tested independently, achieving the effect of centralized testing of multiple stepper driver bodies, saving time and effort, and improving the testing efficiency of the device.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1 to 5 A centralized testing device for stepper drivers, comprising:

[0026] The test motor 2 is fixedly installed inside the right-angle bracket 1, and a controller 6 is fixedly installed on the outside of the right-angle bracket 1. The surface of the controller 6 is equipped with a touch screen 17 and multiple buttons 18. The touch screen 17 can perform corresponding operations and also display the data monitored by the sensor 5.

[0027] Furthermore, each of the multiple buttons 18 corresponds one-to-one with a multiple stepper driver body 4. The side view of each button 18 corresponds one-to-one with the top view of the multiple stepper driver bodies 4. That is, pressing one of the buttons 18 will connect the corresponding stepper driver body 4 to the circuit of the device. Then, the specified command is issued through the touch screen 17, and the corresponding stepper driver body 4 is used to control the test motor 2 to react. That is, each stepper driver body 4 can be tested independently. Finally, the above operation is repeated. By pressing different buttons 18, the effect of centralized testing of multiple stepper driver bodies 4 can be achieved. In the idle space of this device, all the above-mentioned electrical components, which refer to power components, and electrical components and power supply are connected by wires. The specific connection method should refer to the working principle in this technical solution. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0028] A fixing plate 3 is fixedly installed on the top of the right-angle base 1. Multiple stepper driver bodies 4 are inserted into the top of the fixing plate 3. Multiple positioning slots 13 are opened on the top of the fixing plate 3, and the positioning slots 13 match the stepper driver bodies 4. Multiple circuit boards 14 are fixedly installed in each positioning slot 13. Multiple conductive sheets 15 are installed on the surface of each circuit board 14, and the conductive sheets 15 are electrically connected to the corresponding stepper driver body 4, so that after the stepper driver body 4 is placed into the positioning slot 13, the stepper driver body 4 can be connected to the circuit of the entire device.

[0029] Furthermore, a sensor 5 is fixedly installed on the side of the fixed plate 3 to monitor the differences in the actions performed by the test motor 2 under the command of each stepper driver body 4.

[0030] The clamping assembly includes two brackets 7 fixedly mounted on the side of the fixed plate 3. A rotating shaft 8 is rotatably mounted between the two brackets 7. A gear 10 is fixedly mounted on the surface of the rotating shaft 8, and multiple pressure rods 9 are fixedly mounted on the surface of the rotating shaft 8. The multiple pressure rods 9 are all fixedly positioned directly above the corresponding stepper driver body 4. A screw 11 is threaded through the top of the fixed plate 3. A knob 16 is fixedly mounted on the bottom of the screw 11. Multiple discs 12 are fixedly mounted on a section of the screw 11 above the fixed plate 3, and the multiple discs 12 mesh with the gear 10.

[0031] Furthermore, the controller 6 is equipped with an indicator light 19 and a buzzer 20. During the test, when the indicator light 19 flashes and the buzzer 20 sounds, it indicates that there is an abnormality in the stepper driver body 4, so as to remind the staff.

[0032] The working principle of this utility model is as follows:

[0033] In use, first place each stepper driver body 4 into each positioning slot 13. Then, rotate the screw 11 by the knob 16 to make each disc 12 spiral downward. At this time, the disc 12 can rotate downward by the rotating shaft 8 through the gear 10 to drive each pressure rod 9 to flip downward until it presses the top of each stepper driver body 4, thus fixing it in the corresponding positioning slot 13 and connecting it to the circuit of this device, completing the fixation of the stepper driver body 4 and ensuring the stability of the stepper driver body 4 during the test.

[0034] Subsequently, a specified command is issued through the touch screen 17, and the corresponding stepper driver body 4 is used to control the test motor 2 to react. That is, each stepper driver body 4 can be tested independently. Finally, the above operation is repeated by pressing different buttons 18 to achieve the effect of centralized testing of multiple stepper driver bodies 4.

[0035] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
