[0024] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0025] Please see Figures 1 to 2 , Figure 5 , Figure 1 This is a three-dimensional structural schematic diagram of the insulation testing device 100 according to one embodiment of the present utility model; Figure 2 yes Figure 1 Side view of the insulation testing device 100; Figure 5 yes Figure 1 A three-dimensional structural schematic diagram of the carrier 210. This utility model provides an insulation testing device 100, which includes a base 10, a conductive probe 20, a lifting mechanism 30, and a testing module. The conductive probe 20 is mounted on the base 10; the lifting mechanism 30 includes a driving member 31 and a pushing plate 32, with the pushing plate 32 spaced apart from the conductive probe 20. The gap between the pushing plate 32 and the conductive probe 20 allows the carrier 210, which carries a workpiece 300, to pass through. The driving member 31 is mounted on the base 10 and connected to the pushing plate 32, and can drive the pushing plate 32 to push the workpiece 300 on the carrier 210 until it abuts against the conductive probe 20; the testing module is electrically connected to the conductive probe 20 and the pushing plate 32 to obtain the resistance value of the workpiece 300.

[0026] Specifically, the conductive probe 20 and the push plate 32 are arranged at intervals along the Z direction, the driving direction of the drive unit 31 is parallel to the Z direction, the detection module outputs a high level to the conductive probe 20 and grounds the push plate 32, and a feed trough 11 is provided on the base 10.

[0027] Understandably, during the production process, the carrier 210 is transported on a conveyor line. The conveyor line can transport the carrier 210 from the feed chute 11 along the X direction to the gap between the conductive probe 20 and the push plate 32. The push plate 32 can push the workpiece 300 on the carrier 210 towards the conductive probe 20 along the Z direction, so that the workpiece 300 is in a state where it is jointly clamped by the push plate 32 and the conductive probe 20. In this state, current can flow from the conductive probe 20 through the workpiece 300 to the push plate 32. The detection module can obtain the resistance value of the workpiece 300 by collecting the current on the conductive probe 20. After the detection module completes the detection of the workpiece 300, when the drive unit 31 drives the push plate 32 to move away from the conductive probe 20 along the Z direction, the workpiece 300 falls back to the carrier 210, so that the conveyor line can drive the carrier 210 to move the workpiece 300 away from the gap between the conductive probe 20 and the push plate 32. It should be understood that in some other embodiments, the carrier 210 may move along the Y direction into the gap between the conductive probe 20 and the push plate 32, and the detection module may obtain the resistance of the workpiece 300 by collecting the current on the push plate 32.

[0028] The insulation testing device 100 of this utility model has a gap between the push plate 32 and the conductive probe 20 for the carrier 210 carrying the workpiece 300 to pass through. The driving member 31 can drive the push plate 32 to push the workpiece 300 on the carrier 210 to abut against the conductive probe 20, so that the detection module can obtain the resistance value of the workpiece 300. During the detection process, there is no need to manually transfer the workpiece 300 on the carrier 210, thereby improving the detection efficiency of the workpiece 300.

[0029] Please see Figures 1 to 2 , Figure 5 In one embodiment of this implementation, the lifting mechanism 30 further includes a slider 35 and a slide rail 36. The slide rail 36 is mounted on the base 10, the slider 35 slides in conjunction with the slide rail 36, the push plate 32 is mounted on the slider 35, and the drive member 31 can drive the push plate 32 to move along the slide rail 36.

[0030] Specifically, the slide rail 36 extends along the Z direction, and the slider 35 can slide and cooperate with the slide rail 36 along the Z direction. There are two slide rails 36, which are spaced apart on the base 10 along the X direction. There are two sliders 35, which cooperate with the two slide rails 36 in a one-to-one correspondence. Both sliders 35 are connected to the push plate 32.

[0031] It is understandable that by setting slider 35 and slide rail 36, a sliding connection between push plate 32 and base 10 can be achieved. The presence of two sliders 35 and two slide rails 36 is beneficial for improving the stability of push plate 32 when driven by drive member 31.

[0032] Please see Figures 1 to 2 , Figure 5In one embodiment of this implementation, the driving component 31 is a push rod motor, which is located on the side of the push plate 32 away from the conductive probe 20.

[0033] Specifically, the drive unit 31, the push plate 32, and the conductive probe 20 are arranged sequentially along the Z-direction. It is understood that the driving force of the push rod motor on the push plate 32 is adjustable, allowing for adjustable clamping force when the push plate 32 and the conductive probe 20 hold the workpiece 300. This helps reduce the risk of poor contact between the conductive probe 20 and the workpiece 300, thereby improving the accuracy of resistance detection of the workpiece 300. The push rod motor is located on the side of the push plate 32 opposite to the conductive probe 20, which simplifies the structure.

[0034] Please see Figures 1 to 2 , Figure 4 , Figure 4 yes Figure 1 A three-dimensional structural schematic diagram of the conductive probe 20. In one embodiment of this invention, the conductive probe 20 is formed with a bearing surface 21 for bearing against the workpiece 300.

[0035] Specifically, the insulation testing device 100 also includes a conductive base 22, which is connected to the base 10. A conductive probe 20 is fixed to the conductive base 22. The conductive probe 20 is made of copper, and its abutment plane 21 is perpendicular to the Z-direction. It is understood that the abutment plane 21 increases the contact area between the conductive probe 20 and the workpiece 300, which helps reduce the risk of poor contact between the conductive probe 20 and the workpiece 300, thereby improving the accuracy of the resistance detection of the workpiece 300. Using copper for the conductive probe 20 helps reduce its internal resistance, thus reducing the interference caused by the internal resistance of the conductive probe 20 on the measurement results.

[0036] Please see Figures 1 to 2 , Figure 4 In one embodiment of this implementation, multiple conductive probes 20 are spaced apart.

[0037] Specifically, four conductive probes 20 are provided, arranged at intervals along the X direction, and all are mounted on the conductive base 22. It can be understood that by providing multiple conductive probes 20, the insulation testing device 100 can simultaneously test multiple workpieces 300, which helps improve the testing efficiency of the insulation testing device 100.

[0038] Please see Figures 1 to 4 , Figure 3 yes Figure 1A three-dimensional structural diagram of the push plate 32, lifting block 33, and positioning element 34 of the insulation testing device 100. In one embodiment of this implementation, the push plate 32 is provided with a plurality of lifting blocks 33, and the plurality of lifting blocks 33 are arranged in a one-to-one correspondence with a plurality of conductive probes 20. The lifting blocks 33 are electrically connected to the testing module and are used to abut against the workpiece 300.

[0039] Specifically, four lifting blocks 33 and four conductive probes 20 are provided. The four lifting blocks 33 are arranged at intervals along the X direction. Each lifting block 33 forms a lifting surface 331 perpendicular to the Z direction. The lifting surface 331 is used to abut against the workpiece 300. In the plane perpendicular to the Z direction, the projection of the lifting block 33 and the projection of the conductive probe 20 partially overlap. It can be understood that by setting multiple lifting blocks 33 on the push plate 32, the push plate 32 can push multiple workpieces 300 to abut against the conductive probe 20 in one lifting action, and the lifting blocks 33 and conductive probes 20 can clamp multiple workpieces 300 one by one. The detection module is electrically connected to multiple conductive probes 20 and multiple lifting blocks 33 respectively, so that the lifting blocks 33 and conductive probes 20 can form multiple independent circuits corresponding to the workpieces 300. This allows the detection module to simultaneously obtain the resistance values ​​of multiple workpieces 300, which is beneficial to improving detection efficiency. The lifting block 33 has a lifting surface 331 perpendicular to the Z-direction, which increases the contact area between the lifting block 33 and the workpiece 300. This helps reduce the risk of the workpiece 300 falling when the lifting block 33 pushes it, and also reduces the risk of damage to the workpiece 300 caused by the lifting block 33. The projection of the lifting block 33 and the projection of the conductive probe 20 partially overlap, which helps to firmly clamp the workpiece 300 with the lifting block 33 and the conductive probe 20, thereby improving the accuracy of the detection results of the workpiece 300.

[0040] Please see Figures 1 to 5 In one embodiment of this implementation, a positioning member 34 is provided on the push plate 32. The positioning member 34 is used to abut against the carrier 210 to restrict the movement of the carrier 210 relative to the push plate 32.

[0041] Specifically, the positioning element 34 is a positioning pin. One end of the positioning element 34 is connected to the push plate 32, and the other end extends relative to the push plate 32 along the Z direction. It can be understood that as the push plate 32 moves towards the workpiece 300 along the Z direction, the positioning element 34 can abut against the carrier 210 and provide a force perpendicular to the Z direction to the carrier 210. This restricts the carrier 210 from moving perpendicular to the Z direction relative to the push plate 32 and the conductive block, thereby reducing the risk of the workpiece 300 falling under the push of the push plate 32 and the risk that the push plate 32 and the conductive block cannot cooperate to clamp the workpiece 300.

[0042] Please see Figures 1 to 5Secondly, the present invention provides a conveying device, which includes a conveying line, a carrier 210 and an insulation testing device 100 according to any embodiment of the first aspect. The base 10 is connected to the conveying line, the carrier 210 is used to carry the workpiece 300, and the conveying line can convey the carrier 210 between the conductive probe 20 and the push plate 32.

[0043] Specifically, the base 10 can be installed on the conveyor line by welding, magnetic attraction, bolting, or adhesive bonding. The conveyor line extends along the X direction and passes through the gap between the conductive probe 20 and the push plate 32. This arrangement allows the conveyor line to transport the carrier 210 along the X direction through the feed chute 11 to the gap between the conductive probe 20 and the push plate 32, thereby enabling the insulation testing device 100 to test the workpiece 300 on the carrier 210. By incorporating the insulation testing device 100 from the first aspect of this invention into the conveying equipment, the testing efficiency of the workpiece 300 can be improved.

[0044] Please see Figures 1 to 6 , Figure 6 yes Figure 5 A three-dimensional structural schematic diagram of the carrier 210 from another perspective. In one embodiment of this implementation, the carrier 210 has a plurality of receiving holes 211 penetrating the carrier 210. The receiving holes 211 are used to receive the workpiece 300. The push plate 32 can approach the receiving hole 211 from the side of the carrier 210 toward the push plate 32 to push the workpiece 300 out of the receiving hole 211 from the side of the carrier 210 toward the conductive probe 20.

[0045] Specifically, the carrier 210 is fixed on the conveyor belt, and the receiving hole 211 penetrates the carrier 210 along the Z direction. The wall of the receiving hole 211 can abut against the workpiece 300. When the workpiece 300 is located in the receiving hole 211, part of the workpiece 300 is exposed on the side of the carrier 210 facing the push plate 32, and the other part of the workpiece 300 is exposed on the side of the carrier 210 facing the conductive probe 20. It can be understood that when the receiving hole 211 penetrates the carrier 210 along the Z direction, and the push plate 32 moves towards the conductive probe 20, a force can be applied to the workpiece 300 from the side of the workpiece 300 away from the conductive probe 20 on the carrier 210, so as to drive the workpiece 300 away from the receiving hole 211 and move the workpiece 300 to abut against the conductive probe 20. When the push plate 32 moves away from the conductive probe 20, it can bring the workpiece 300 closer to the carrier 210 and into the receiving hole 211. With this configuration, the drive unit 31 does not need to push the carrier 210 so that the carrier 210 moves with the workpiece 300 towards the conductive probe 20 in the Z direction. This reduces the risk of inaccurate detection results caused by the carrier 210 obstructing contact between the workpiece 300 and the conductive probe 20, and also reduces the driving force required by the drive unit 31. The carrier 210 is fixed to the conveyor belt, which reduces the risk of the carrier 210 falling off the conveyor belt when the push plate 32 pushes the workpiece 300 out of the receiving hole 211.

[0046] Please see Figures 1 to 6 In one embodiment of this implementation, the carrier 210 is provided with an inclined surface 212. When the push plate 32 moves, the push plate 32 can abut against the inclined surface 212 to correct the position of the carrier 210 relative to the push plate 32.

[0047] Specifically, the inclined plane 212 is parallel to the Y direction and intersects the Z direction. With this configuration, as the push plate 32 moves along the Z direction, the carrier 210 and the push plate 32 slide relative to each other along the inclined plane 212, thereby changing the relative position of the carrier 210 and the push plate 32 along the X direction. This allows for the correction of the position of the carrier 210 relative to the push plate 32 along the X direction, reducing the risk that the push plate 32 may fail to push the workpiece 300 due to the misalignment of the carrier 210 and the push plate 32.

[0048] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
