Description

Technical Field

[0001] This utility model relates to fixtures, and more particularly to a test fixture for a robot drive control cabinet. Background Technology

[0002] Industrial robots typically require robot drive and control cabinets to control their movement. After assembly, these cabinets need to undergo functional testing. Currently, the common practice is to connect the robot drive and control cabinet to the industrial robot for actual testing. The robot's joints are moved by controlling the robot's drive and control cabinet, and the joint movements are observed to determine if they meet the requirements. This helps to determine if the robot drive and control cabinet is functioning properly. However, because robot movement requires a lot of space, and if the robot drive and control cabinet is not functioning properly, it may cause one of the robot's joints to rotate excessively during testing, damaging the robot used for testing. This makes testing quite inconvenient. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a robot drive and control cabinet test fixture, which has the advantage of making the testing process more convenient.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a test fixture for a robot drive and control cabinet, including: a base plate, a top plate, a motor, a power supply, and a control module. The top plate is fixed above the base plate by a side plate, and the motor is fixed to the bottom surface of the top plate. A first clearance hole is provided on the top plate for the motor's rotating shaft to extend out. The power supply and control module are fixed to the base plate. The control module is electrically connected to the power supply and the motor. An internal encoder is coaxially connected to the motor. The robot drive and control cabinet can be detachably electrically connected to the control module. The robot drive and control cabinet can control the rotation of the motor, and the control module can detect the number of rotations of the motor through the internal encoder.

[0005] Optionally, an external encoder is also included. The external encoder is fixed to the bottom surface of the top plate. A second clearance hole is provided on the top plate for the detection end of the external encoder to extend out. A first transmission wheel is provided on the motor adjacent to the external encoder, and a second transmission wheel is provided on the detection end of the external encoder. The first transmission wheel and the second transmission wheel are connected by a transmission belt, and the motor can drive the detection end of the external encoder to rotate.

[0006] Optionally, a top cover is also included, with positioning pins on both sides of the top plate and a U-shaped groove at the bottom of the top cover. The top cover can be placed on the top plate, and the positioning pins can be engaged in the U-shaped groove. The top cover is made of transparent material, and openings for wiring are provided on the side plates.

[0007] Alternatively, the motor may be a servo motor.

[0008] Optionally, it also includes a front plate, a rear plate, a terminal block, a relay, a power indicator light, and a test indicator light. The front plate and the rear plate are respectively fixed to the front end and the rear end of the side plate. The power indicator light and the test indicator light are fixed to the front plate. The power indicator light is electrically connected to the power supply. The terminal block and the relay are fixed to the top surface of the base plate. The power supply, the motor, the internal encoder, the external encoder, the relay, and the test indicator light are electrically connected to the control module through the terminal block. The top plate has an observation port at the position corresponding to the control module.

[0009] Alternatively, the number of motors is six, the number of external encoders is two, and the drive belt is a toothed drive belt.

[0010] Alternatively, the top cover may be made of transparent plexiglass.

[0011] Alternatively, the first and second drive wheels may have the same diameter.

[0012] The beneficial technical effects of this utility model are as follows: The robot drive control cabinet test fixture includes a base plate, a top plate, a motor, a power supply, and a control module. In use, the robot drive control cabinet is first electrically connected to the control module. Then, the robot drive control cabinet drives the motor to rotate a specific number of revolutions through the control module. An internal encoder detects the number of revolutions and inputs it into the control module. The control module compares the actual number of revolutions with the set number. If they match, the robot drive control cabinet is functioning normally. Since the robot's joints are driven by the motor's rotation, controlling the motor to rotate a specific number of revolutions simulates the robot joint swinging at a specific angle. By comparing the actual number of revolutions with the set value, the normal functioning of the robot drive control cabinet is determined. This eliminates the need for an additional robot for testing and provides space for robot movement. When the robot drive control cabinet malfunctions, it only affects the number of motor revolutions and does not damage the robot joints due to excessive rotation angles. This is more convenient than using a robot for testing and offers the advantage of a more convenient testing process. Attached Figure Description

[0018] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0019] This specific embodiment details the robot drive and control cabinet test fixture described in this application, such as... Figures 1-3 As shown, the robot drive control cabinet test fixture includes: a base plate 1, a top plate 2, a motor 3, a power supply 4, and a control module 5. The top plate 2 is fixed above the top plate 2 by a side plate 6. The motor 3 is fixed to the bottom surface of the top plate 2. The top plate 2 has a first clearance hole for the rotation shaft of the motor 3 to extend out. The power supply 4 and the control module 5 are fixed to the base plate 1. The control module 5 is electrically connected to the power supply 4 and the motor 3. The motor 3 is coaxially connected to an internal encoder. The robot drive control cabinet can be detachably electrically connected to the control module 5. The robot drive control cabinet can control the rotation of the motor 3. The control module 5 can detect the number of rotations of the motor 3 through the internal encoder. In use, the robot drive control cabinet is first electrically connected to the control module 5. The robot drive control cabinet then drives the motor 3 to rotate a specific number of revolutions via the control module 5. The internal encoder detects the number of revolutions of the motor 3 and inputs it into the control module 5. The control module 5 compares the actual number of revolutions with the set number. If they match, the robot drive control cabinet is functioning correctly. Since the robot's joints are driven by motor rotation, controlling the motor 3 to rotate a specific number of revolutions simulates the robot joint swinging at a specific angle. By comparing the actual number of revolutions of the motor with the set value, the function of the robot drive control cabinet is determined. This eliminates the need for an additional robot for testing and provides space for robot movement. When the robot drive control cabinet malfunctions, it only affects the number of revolutions of the motor 3, without damaging the robot joints due to excessive rotation angles. This is more convenient than using a robot for testing and offers the advantage of a more convenient testing process. In this embodiment, the motor 3 with the internal encoder is a commercially available product.

[0020] Optionally, this embodiment also includes an external encoder 7, which is fixed to the bottom surface of the top plate 2. The top plate 2 has a second clearance hole for the detection end of the external encoder 7 to extend out. A first transmission wheel 8 is provided on the motor 3 adjacent to the external encoder 7, and a second transmission wheel 9 is provided on the detection end of the external encoder 7. The first transmission wheel 8 and the second transmission wheel 9 are connected by a transmission belt 10, and the motor 3 can drive the detection end of the external encoder 7 to rotate. Currently, robotic arms on the market are usually equipped with external encoders to calibrate and detect joint angles. These external encoders are driven and acquire data through the robot drive control cabinet. Therefore, the robot drive control cabinet also needs to test the functionality of its external encoder when it leaves the factory. The testing principle is as follows: the motor 3 drives the detection end of the external encoder 7 to rotate through the transmission belt 10. Since the motor 3 has an internal encoder, the user can know the actual number of rotations of the motor 3. At the same time, the transmission ratio of the first transmission wheel 8 and the second transmission wheel 9 is also known (in this embodiment, the transmission ratio is 1:1). Therefore, the actual number of rotations of the detection end of the external encoder 7 is also known. The user only needs to check whether the robot drive control cabinet can receive the rotation signal of the external encoder 7 and whether the received rotation signal of the external encoder 7 is consistent with the actual number of rotations to test whether the external encoder function of the robot drive control cabinet is normal. Usually, the test of the external encoder 7 is carried out after the motor drive function test is completed.

[0021] Optionally, this embodiment also includes a top cover 11. Positioning pins 12 are provided on both sides of the top plate 2. A U-shaped groove is formed at the bottom of the top cover 11, allowing it to cover the top plate 2. The positioning pins 12 can be engaged in the U-shaped groove. The top cover 11 is made of transparent material, and openings for wiring are provided on the side plate 6. During testing, the top cover 11 can cover the top plate 2 to prevent accidental contact with the rotating motor 3. The transparent material of the top cover 11 facilitates observation.

[0022] Optionally, in this embodiment, motor 3 is a servo motor.

[0023] Optionally, this embodiment also includes a front plate 13, a rear plate, a terminal block 14, a relay 15, a power indicator light, and a test indicator light. The front plate 13 and the rear plate are respectively fixed to the front end and rear end of the side plate 6. The power indicator light and the test indicator light are fixed to the front plate 13. The power indicator light is electrically connected to the power supply 4. The terminal block 14 and the relay 15 are fixed to the top surface of the base plate 1. The power supply 4, the motor 3, the internal encoder, the external encoder 7, the relay 15, and the test indicator light are electrically connected to the control module 5 through the terminal block 14. The top plate 2 has an observation port 16 at the position corresponding to the control module 5. The control module 5 can control the test indicator light to emit different colors to indicate the test results. The observation port 16 allows the user to easily observe the operating status of the control module 5, such as checking if any fault lights are on.

[0024] Optionally, in this embodiment, the number of motors 3 is six, the number of external encoders 7 is two, and the transmission belt 10 is a toothed transmission belt.

[0025] Optionally, in this embodiment, the top cover 11 is made of transparent plexiglass.

[0026] Optionally in this embodiment, the first transmission wheel 8 and the second transmission wheel 9 have the same diameter.

[0027] Using the robot drive control cabinet test fixture in this embodiment has the advantage of making the testing process more convenient.
