[0002] In the production and quality inspection of electrical products such as motors, electrical testing is a crucial step in ensuring product quality and performance stability. Traditional testing methods typically rely on manual operation, where workers use testing tools to test each workpiece individually. This method has advantages in practical applications, such as simple structure and low cost, and is particularly suitable for small-batch or non-continuous production scenarios. However, as industrial manufacturing moves towards automation and intelligence, manual inspection has gradually revealed problems such as low efficiency, high labor intensity, and poor consistency, making it difficult to meet the modern enterprise's production demands for both high efficiency and high quality.

[0003] Manual electrical testing requires operators to manually place the workpiece, control the contact of the testing probe, and read the test results. This method is not only cumbersome and time-consuming, but also susceptible to human factors such as fatigue, misjudgment, and missed detections, leading to unstable test quality.

[0004] The purpose of this invention is to solve the problems of slow detection efficiency and low accuracy caused by the need for manual testing in traditional electrical testing equipment. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1 to 6As shown, this utility model proposes an electrical testing device, including a workbench 1, a support 2 on the workbench 1, and at least one electrical testing station 3 mounted on the workbench 1. The electrical testing station 3 includes a first linear actuator 31, and at least one detection terminal 33 is provided at the power output end of the first linear actuator 31. The support 2 is positioned above the first linear actuator 31 and has a station for placing the workpiece to be tested. In use, the workpiece to be tested is placed in the station on the support 2, which is located above the first linear actuator 31. During testing, the first linear actuator 31 drives the detection terminal 33 to move upward toward and contact the workpiece, thereby achieving electrical testing. This process achieves automated testing operation, eliminating the need for manual contact testing and effectively solving the problem of low efficiency caused by the reliance on manual testing in traditional electrical testing equipment.

[0030] Optionally, in some embodiments, the first linear actuator 31 is one or more of an electric actuator, a cylinder, and a hydraulic cylinder.

[0031] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, a placement disk 34 is provided above the first linear actuator 31. The placement disk 34 is mounted on the workstation provided on the support 2 for placing the workpiece to be tested. The placement disk 34 is used to place the workpiece to be tested. The placement disk 34 is provided with a retaining ring 341, and the retaining ring 341 has at least one clearance groove 342. The position of the clearance groove 342 corresponds to the detection terminal 33, and the clearance groove 342 is used for the detection terminal 33 to pass through. When the first linear actuator 31 drives the detection terminal 33 to move upward, the detection terminal 33 can accurately contact the workpiece through the corresponding clearance groove 342 to complete the electrical test. This structure ensures that the detection terminal 33 can be accurately aligned and reduces the risk of accidental contact, improving the stability and accuracy of the test. The retaining ring 341 can position and fix the workpiece to be tested, preventing the workpiece from shifting or shaking during the test, thereby ensuring the accuracy of the test. At the same time, the retaining ring 341 can provide guidance for the placement of the workpiece to be tested.

[0032] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, a terminal base 32 is mounted on the power output end of the first linear driver 31, and the detection terminal 33 is mounted on the terminal base 32. When it is necessary to adapt to different models or specifications of workpieces to be inspected, the detection terminal 33 can be quickly replaced and adjusted simply by replacing the corresponding terminal base 32. This structural design allows the device to flexibly adapt to various inspection needs, improving the versatility and ease of use of the equipment.

[0033] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, a rotary clamping driver 35 mounted on the support 2 is provided on one side of the placement tray 34. The rotary clamping driver 35 is used to limit the position of the workpiece to be inspected. A clamping block 36 is installed at the power output point of the rotary clamping driver 35. The clamping block 36 is used to clamp and limit the workpiece to be inspected placed on the placement tray 34. When the workpiece to be inspected is placed on the placement tray 34, the rotary clamping driver 35 is activated, driving the clamping block 36 to rotate and move closer to the workpiece, thereby clamping and fixing the workpiece. This structure, in conjunction with the retaining ring 341, further prevents the workpiece from shifting or shaking during the inspection process, ensuring that the inspection terminal 33 can accurately contact the workpiece.

[0034] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the workbench 1 is provided with a clamping mechanism 4, the clamping mechanism 4 including a base 41, a sliding plate 44 slidably connected to the base 41, a third linear actuator 47 being provided on one side of the sliding plate 44, and at least one clamping actuator 49 being provided at the power output end of the third linear actuator 47 for clamping a workpiece. A connecting plate 48 is mounted on the power output end of the third linear actuator 47, and the clamping actuator 49 is mounted on the connecting plate 48. A linear motor is mounted on the base 41, and the linear motor is used to drive the sliding plate 44 to slide along the guide direction of the slide rail 42. A top plate 45 is slidably connected to the sliding plate 44, the third linear actuator 47 is mounted on one side of the top plate 45, and a second linear actuator 46 is mounted on the sliding plate 44, the power output end of the second linear actuator 46 being fixedly connected to the top plate 45. When workpieces need to be moved or loaded / unloaded, the third linear actuator 47 drives the clamping actuator 49 to move above the workpiece, and the clamping actuator 49 clamps the workpiece. Subsequently, the linear motor starts, driving the slide plate 44 to slide along the slide rail 42, moving the clamped workpiece to the target position, completing the automatic clamping and moving operation. This further improves the automation level of the entire electrical testing device, increases the working efficiency of the equipment, reduces manual intervention, and enhances the adaptability of the equipment in multi-station collaboration and continuous testing scenarios.

[0035] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, a top plate 45 is slidably connected to the slide plate 44, a third linear actuator 47 is mounted on one side of the top plate 45, a second linear actuator 46 is mounted on the slide plate 44, the power output end of the second linear actuator 46 is fixedly connected to the top plate 45, a slide rail 42 is mounted on the base 41, a slide block 43 is slidably engaged with the slide rail 42, and the slide block 43 is fixedly connected to the slide plate 44. The sliding direction of the top plate 45 is perpendicular to the sliding direction of the slide plate 44 along the slide rail 42. This constitutes a three-dimensional motion structure with XY-direction linkage, enabling the clamping mechanism to accurately position and transport the workpiece in multiple directions.

[0036] Optionally, in some embodiments, the second linear actuator 46 and the third linear actuator 47 are one or more combinations of electric actuators, cylinders, and hydraulic cylinders.

[0037] Example 1:

[0038] This invention proposes an electrical testing device, including a workbench 1, a support 2 on the workbench 1, and at least one electrical testing station 3 mounted on the workbench 1. The electrical testing station 3 includes a first linear actuator 31, which is one or more combinations of an electric push rod, a cylinder, and a hydraulic cylinder. At least one detection terminal 33 is provided at the power output end of the first linear actuator 31. The support 2 is positioned above the first linear actuator 31 and has a station for placing the workpiece to be tested. In use, the workpiece to be tested is placed in the station on the support 2, which is located above the first linear actuator 31. During testing, the first linear actuator 31 drives the detection terminal 33 to move upward toward and contact the workpiece, thereby achieving electrical testing. This process achieves automated testing, eliminating the need for manual contact testing and effectively solving the problem of low efficiency caused by the reliance on manual testing in traditional electrical testing equipment.

[0039] A placement tray 34 is disposed above the first linear actuator 31. The placement tray 34 is mounted on the workstation of the support 2 for placing the workpiece to be tested. The placement tray 34 is used to place the workpiece to be tested. The placement tray 34 is provided with a retaining ring 341, which has at least one clearance groove 342. The clearance groove 342 is positioned corresponding to the detection terminal 33 and is used to allow the detection terminal 33 to pass through. When the first linear actuator 31 drives the detection terminal 33 to move upward, the detection terminal 33 can accurately contact the workpiece through the corresponding clearance groove 342 to complete the electrical test. This structure ensures that the detection terminal 33 can be accurately aligned and reduces the risk of accidental contact, thereby improving the stability and accuracy of the test. The retaining ring 341 can position and fix the workpiece to be tested, preventing the workpiece from shifting or shaking during the test, thereby ensuring the accuracy of the test. At the same time, the retaining ring 341 can provide guidance for the placement of the workpiece to be tested. A terminal base 32 is installed at the power output end of the first linear actuator 31, and the detection terminal 33 is installed on the terminal base 32. When it is necessary to adapt to different models or specifications of workpieces to be inspected, the detection terminals 33 can be quickly replaced and adjusted simply by changing the corresponding terminal base 32. This structural design allows the device to flexibly adapt to various inspection needs, improving the versatility and ease of use of the equipment.

[0040] A rotary clamping driver 35, mounted on a support 2, is provided on one side of the placement tray 34. The rotary clamping driver 35 is used to limit the movement of the workpiece to be inspected. A clamping block 36 is installed at the power output point of the rotary clamping driver 35. The clamping block 36 is used to clamp and limit the workpiece placed on the placement tray 34. When the workpiece to be inspected is placed on the placement tray 34, the rotary clamping driver 35 is activated, driving the clamping block 36 to rotate and move closer to the workpiece, thereby clamping and fixing the workpiece. This structure, in conjunction with the retaining ring 341, further prevents the workpiece from shifting or shaking during the inspection process, ensuring that the inspection terminal 33 can accurately contact the workpiece.

[0041] The worktable 1 is equipped with a clamping mechanism 4, which includes a base 41. A sliding plate 44 is slidably connected to the base 41. A third linear actuator 47 is located on one side of the sliding plate 44. At least one clamping actuator 49 is located at the power output end of the third linear actuator 47, and the clamping actuator 49 is used to clamp the workpiece. A connecting plate 48 is installed at the power output end of the third linear actuator 47, and the clamping actuator 49 is installed on the connecting plate 48. A linear motor is installed on the base 41, and the linear motor is used to drive the sliding plate 44 to slide along the guide direction of the slide rail 42. A top plate 45 is slidably connected to the sliding plate 44. The third linear actuator 47 is installed on one side of the top plate 45. A second linear actuator 46 is installed on the sliding plate 44. The second linear actuator 46 and the third linear actuator 47 are one or more combinations of electric push rods, cylinders, and hydraulic cylinders. The power output end of the second linear actuator 46 is fixedly connected to the top plate 45. When workpieces need to be moved or loaded / unloaded, the third linear actuator 47 drives the clamping actuator 49 to move above the workpiece, and the clamping actuator 49 clamps the workpiece. Then, the linear motor starts, driving the slide plate 44 to slide along the slide rail 42, moving the clamped workpiece to the target position, completing the automatic clamping and moving operation. This further improves the automation level of the entire electrical testing device, increases the equipment's working efficiency, reduces manual intervention, and enhances the equipment's adaptability in multi-station collaboration and continuous testing scenarios. A top plate 45 is slidably connected to the slide plate 44. The third linear actuator 47 is installed on one side of the top plate 45. A second linear actuator 46 is installed on the slide plate 44, and the power output end of the second linear actuator 46 is fixedly connected to the top plate 45. A slide rail 42 is installed on the base 41, and a slide block 43 is slidably fitted onto the slide rail 42. The slide block 43 is fixedly connected to the slide plate 44. The sliding direction of the top plate 45 is perpendicular to the sliding direction of the slide plate 44 along the slide rail 42. This forms a three-dimensional motion structure that is linked in the XY direction, enabling the clamping mechanism to accurately position and transport the workpiece in multiple directions.

[0042] Specifically, the working principle of this utility model is as follows:

[0043] Before the inspection begins, the clamping mechanism 4 automatically loads the workpiece. A linear motor in the clamping mechanism 4 drives the slide plate 44 to move along the slide rail 42 to the predetermined picking position. The second linear actuator 46 adjusts the lateral position of the top plate 45, and the third linear actuator 47 controls the clamping actuator 49 to descend to the workpiece gripping height. After the clamping actuator 49 actuates, it clamps the workpiece to be inspected. Subsequently, the third linear actuator 47 rises, lifting the workpiece to a safe height, and the slide plate 44 slides again along the slide rail 42 above the support 2. The clamping actuator 49 releases the workpiece, allowing it to fall accurately into the designated position on the placement tray 34. At this time, the retaining ring 341 positions and guides the workpiece, ensuring it is in the correct inspection position. Simultaneously, the rotary clamping actuator 35 activates, causing the clamping block 36 to rotate and move closer to the workpiece, achieving clamping and limiting of the workpiece to prevent it from shifting or shaking during subsequent inspection.

[0044] Once the workpiece is stably fixed on the placement tray 34, the electrical testing station 3 begins operation. The first linear actuator 31, acting as the power source, starts according to a preset program and pushes the terminal base 32 upwards, causing the testing terminal 33 to rise along with it. The testing terminal 33 precisely contacts the test point on the workpiece along the path of the clearance groove 342 on the retaining ring 341, thus establishing a stable electrical connection. Through this electrical connection, the system can test the workpiece for electrical parameters such as resistance, continuity, and insulation performance. Because the position of the clearance groove 342 corresponds one-to-one with the testing terminal 33, accidental or misaligned contact is effectively avoided, improving the accuracy and stability of the test. After completing one test, the first linear actuator 31 resets, causing the testing terminal 33 to detach from the workpiece, ready for the next testing cycle.

[0045] After the electrical testing is completed, the clamping mechanism 4 restarts to automatically unload the workpiece. The entire clamping process is controlled by multiple linear drives and linear motors, achieving multi-degree-of-freedom motion in the XYZ directions to meet the loading and unloading requirements of different positions and postures. Simultaneously, new workpieces to be tested can be fed back into the testing area, forming a continuous testing process. Through this automated operation, this application not only significantly improves testing efficiency but also reduces manual intervention and labor intensity.

[0046] In summary, this invention solves the problems of slow detection efficiency and low accuracy caused by the need for manual testing in traditional electrical testing equipment.
