Description

Technical Field

[0001] This utility model relates to the field of motor processing equipment technology, and in particular to a multi-station motor testing device. Background Technology

[0002] During the manufacturing process, the motor is transported to various processing stations via a conveyor line for different processing steps. Powering on the motor for testing is one such step. When the motor, placed on a carrier, is conveyed to the testing device, the device powers on the motor to perform functional testing. Because the carrier is on the conveyor line, placing the testing device on the same line would only allow for individual motor testing, resulting in low efficiency and failing to meet the demands of high-efficiency motor processing. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a multi-station motor testing device that can test multiple motors simultaneously, thereby improving testing efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a multi-station motor detection device, comprising: The testing mechanism is provided in multiple ways along a first direction. Each testing mechanism includes a robotic arm and a placement frame. The placement frame includes multiple placement positions for placing motors and energizing the motors. The conveyor line is provided in two sections, which are located on both sides of the detection mechanism in the second direction. Each conveyor line includes a conveyor body and a lifting mechanism. The conveyor body conveys a carrier on which the motor is placed along the first direction. The lifting mechanism is correspondingly provided with the detection mechanism. The robot arm moves the motor between the corresponding lifting mechanism and the placement frame. The lifting mechanism includes two lifting plates located on both sides of the conveyor body in a second direction. The two lifting plates are lifted and lowered under the drive of corresponding lifting drive components. Each lifting plate is slidably connected with a rod that can slide along the second direction. The carrier is provided with a hole for inserting the rod. The lifting mechanism can lift the carrier to a first height so that the carrier behind the lifting mechanism can continue to move along the conveyor body. The beneficial effects of this utility model are as follows: by setting up multiple detection mechanisms, and in conjunction with the lifting mechanism that clamps and lifts the carrier from both sides, the carrier can be continuously transported on the conveyor line body, thereby improving the detection efficiency of the motor and enabling more motors to be detected in the same amount of time. Furthermore, a vertical gap is left between the lower surface of the carrier located at the first height and the motor on the carrier on the conveyor body.

[0005] Furthermore, a transverse drive component is fixed on the lifting plate, which drives a connecting plate to slide along a second direction, and multiple insert rods are fixed on the connecting plate.

[0006] Furthermore, a mounting plate is fixed below the conveyor body, and the lifting drive component is fixed on the mounting plate.

[0007] Furthermore, the conveyor body is provided with two stop cylinders at each of the lifting mechanisms to prevent the movement of the carrier on the conveyor body. One stop cylinder is located behind the lifting mechanism in the conveying direction of the conveyor body, and the other stop cylinder is located in front of the lifting mechanism in the conveying direction of the conveyor body.

[0008] Furthermore, the placement positions are arranged in multiple rows along the vertical direction, and each row of placement positions has multiple placement positions arranged along the second direction. Furthermore, the multiple rows of placement positions are arranged in a stepped manner, with the row of placement positions closest to the robotic arm located at the bottom. This stepped distribution of placement positions facilitates the robotic arm in retrieving motors from the placement positions. Even if a motor is present in one placement position, the robotic arm can place another motor in a different placement position without colliding with that motor.

[0009] Furthermore, each of the placement positions includes a positioning block and a detection plug. The positioning block includes a positioning cavity for placing a motor, and the motor includes a socket corresponding to the detection plug.

[0010] Furthermore, each of the placement positions is also equipped with an indicator light to display the test results.

[0011] Furthermore, the robotic arm includes a six-axis robotic arm body and a clamping assembly connected to the output end of the six-axis robotic arm body, the clamping assembly being used to clamp a motor. Attached Figure Description

Detailed Implementation The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0014] In the diagrams below, the X direction is the first direction, and the Y direction is the second direction.

[0015] This utility model discloses a multi-station testing device for motors 4, which can perform simultaneous or sequential testing of multiple motors 4.

[0016] See appendix Figure 1 As shown, the multi-station testing device for motor 4 includes a testing mechanism 1 and a conveyor line 2. The testing mechanism 1 is used for power-on testing of motor 4, and the conveyor line 2 is used for conveying a carrier 3 on which motor 4 is placed. Each carrier 3 has one motor 4 placed on it and is conveyed along the conveyor line 2 to the working area of ​​the testing mechanism 1.

[0017] Multiple detection mechanisms 1 are spaced apart along a first direction. Each detection mechanism 1 includes a robotic arm 11 and a placement rack 12. The placement rack 12 includes multiple placement positions for placing motors 4 and energizing them. For example, there are two detection mechanisms 1, namely a first detection mechanism 1a and a second detection mechanism 1b. Each detection mechanism 1 includes multiple placement positions. The detection of motors 4 requires a certain amount of time. While a motor 4 is being detected at one placement position, the robotic arm 11 can continuously transport motors 4 from the conveyor line 2 to other placement positions for detection.

[0018] Two conveyor lines 2 are provided, located on both sides of the second direction of the testing mechanism 1. The two conveyor lines 2 are a loading conveyor line 2a and a unloading conveyor line 2b. The loading conveyor line 2a is used to transport the motor 4 to be tested, and the unloading conveyor line 2b is used to transport the motor 4 after testing. The robot arm 11 moves the motor 4 on the loading conveyor line 2a and places it in the placement position. The motor 4 is powered on for testing at this position. After the test is completed, the robot arm 11 moves the motor 4 to the unloading conveyor line 2b for unloading.

[0019] See appendix Figure 2 As shown, each conveyor line 2 includes a conveyor line body 21 and a lifting mechanism 22. The conveyor line body 21 conveys a carrier 3 with a motor 4 placed on it along a first direction. The lifting mechanism 22 is set in correspondence with the detection mechanism 1. The robot arm 11 moves the motor 4 between the corresponding lifting mechanism 22 and the placement frame 12. The lifting mechanism 22 lifts the carrier 3 upward to detach it from the conveyor line body 21. At this time, the carrier 3 will not continue to be conveyed by the conveyor line 2, but will be located in a fixed position. The robot arm 11 moves the motor 4 on the lifted carrier 3 or places the motor 4 on the lifted carrier 3. After the lifting mechanism 22 moves the carrier 3 down to abut against the conveyor line body 21, the conveyor line body 21 can continue to convey the carrier 3.

[0020] The lifting mechanism 22 includes two lifting plates 221 located on both sides of the conveyor body 21 in the second direction. The two lifting plates 221 are lifted and lowered under the drive of the corresponding lifting drive component 222. Each lifting plate 221 is slidably connected with a plug rod 223 that can slide along the second direction. The carrier 3 is provided with a plug hole for the plug rod 223 to be inserted. The lifting mechanism 22 can lift the carrier 3 to a first height so that the carrier 3 behind the lifting mechanism 22 can continue to move along the conveyor body 21.

[0021] Compared to the lifting mechanism 22 that rises and falls from the middle of the conveyor body 21, in this embodiment, the lifting plate 221 of the lifting mechanism 22 is located on both sides of the width direction of the conveyor body 21. That is, when the lifting plate 221 rises and falls, it will not interfere with the conveying of the carrier 3 on the conveyor body 21. The lifting mechanism 22 can then clamp the carrier 3. When the insertion rod 223 approaches the carrier 3 along the second direction and inserts into the insertion port, it fixes the carrier 3 and then drives the carrier 3 to rise and fall. At this time, the lifting mechanism 22 will not stop the movement of the subsequent carrier 3. The subsequent carrier 3 can continue to move along the conveyor body 21 to reach the working area of ​​the next detection mechanism 1, reducing the waiting time of the carrier 3 on the conveyor body 21 and allowing the carrier 3 to be continuously conveyed by the conveyor body 21.

[0022] In this embodiment, multiple detection mechanisms 1 are set up, and together with the lifting mechanism 22 that clamps the carrier 3 from both sides and lifts the carrier 3, the carrier 3 can be continuously transported on the conveyor body 21, which improves the detection efficiency of the motor 4 and allows more motors 4 to be detected in the same amount of time.

[0023] See appendix Figure 3 As shown, there is a vertical gap between the lower surface of the carrier 3 located at the first height and the motor 4 on the carrier 3 on the conveyor body 21. That is, for one carrier 3 at the first height, it is necessary to ensure that another carrier 3 with a motor 4 fixed behind it passes underneath it.

[0024] See appendix Figure 2 As shown, a transverse drive component 224 is fixed on the lifting plate 221. The transverse drive component 224 drives a connecting plate 225 to slide in the second direction. Multiple insertion rods 223 are fixed on the connecting plate 225. The number of insertion holes is set according to the number of insertion rods 223. The more insertion rods 223 there are, the more stable the fixation of the carrier 3 is. When the insertion rod 223 is not inserted into the insertion hole, the insertion rod 223 will not extend out of the lifting plate 221 in the second direction, that is, it will not extend above the conveyor body 21, and will not interfere with the carrier 3 conveyed by the conveyor body 21.

[0025] A mounting plate 226 is fixed below the conveyor body 21, and a lifting drive component 222 is fixed on the mounting plate 226. The mounting plate 226 supports the lifting drive component 222, and the position of the mounting plate 226 will not interfere with the transport of the carrier 3 on the conveyor body 21.

[0026] The conveyor body 21 is equipped with two stop cylinders 23 at each lifting mechanism 22. These stop cylinders 23 are used to prevent the movement of the carriers 3 on the conveyor body 21. The two stop cylinders 23 are designated as a first stop cylinder and a second stop cylinder. The first stop cylinder is located behind the lifting mechanism 22 in the conveying direction of the conveyor body 21. When the lifting mechanism 22 is lifting a carrier 3, the first stop cylinder blocks the carrier 3 located behind the lifting mechanism 22 on the conveyor body 21, ensuring that the two carriers 3 do not collide. The first stop cylinder will only release when the lifting mechanism 22 has lifted the carrier 3 to a first height position. The second stop cylinder is located in front of the lifting mechanism 22 in the conveying direction of the conveyor body 21. The second stop cylinder is used to limit the position of the carrier 3, stopping the carrier 3 within the working area of ​​the lifting mechanism 22.

[0027] See appendix Figure 4 As shown, there are multiple rows of placement positions arranged vertically, and each row of placement positions is arranged in multiple directions. At this time, multiple motors 4 can be placed on the placement rack 12 for testing.

[0028] In one embodiment, multiple rows of placement positions are arranged in a stepped manner, with the row of placement positions closest to the robot arm 11 located at the bottom. The stepped distribution of placement positions facilitates the robot arm 11 in picking up and discharging motors 4 from the placement positions. Even if there is a motor 4 on one placement position, the robot arm 11 can place another motor 4 in another placement position without colliding with that motor 4.

[0029] See appendix Figure 5 As shown, each placement position includes a positioning block 121 and a detection plug 122. The positioning block 121 includes a positioning cavity for placing the motor 4, and the motor 4 includes a socket corresponding to the detection plug 122. When the motor 4 is placed on the positioning block 121 and confined within the positioning cavity, the detection plug 122 is aligned with the socket and inserted into it. At this time, the controller detects... Each placement position is also equipped with an indicator light to display the test results. The indicator light is red and green. When the indicator light is red, it means that the motor 4 at that placement position has failed the test, and when the indicator light is green, it means that the motor 4 at that placement position has passed the test. The indicator light setup allows for a quick and intuitive understanding of the motor 4 test results.

[0030] The robotic arm 11 includes a six-axis robotic arm body 111 and a clamping assembly 112 connected to the output end of the six-axis robotic arm body 111. The clamping assembly 112 is used to clamp the motor 4.

[0031] The carrier 3, holding the motor 4 to be tested, is conveyed on the feeding conveyor line 2a. When the carrier 3 reaches the position of the lifting mechanism 22 corresponding to the first testing mechanism 1a, the lifting mechanism 22 lifts the carrier 3 to a first height position. At this time, the robot arm 11 of the first testing mechanism 1a grabs the motor 4 on the carrier 3 at the first height position. The carrier 3 on the feeding conveyor line 2a can pass under the carrier 3 at the first height position and continue to move to the position of the lifting mechanism 22 corresponding to the first testing mechanism 1a, reducing the waiting time of the carrier 3. For the motor 4 that has passed the test on the placement rack 12, the robot arm 11 of the testing mechanism 1 moves the motor 4 to the lifting mechanism 22 corresponding to the unloading conveyor line 2b. The lifting mechanism 22 moves down, causing the carrier 3 to come into contact with the conveyor body 21 of the unloading conveyor line 2b, and it continues to be conveyed.

[0032] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
