[0027] Reference Figures 1 to 3 The utility model discloses a kind of strong current test device, including base plate 400, floating block 200, probe 210 and multiple elastic members 300.Floating block 200 is configured to be connected on base plate 400 along up-down direction slidingly.Probe 210 is located on the lower surface of floating block 200, and probe 210 is used to be in contact with product.The upper end of multiple elastic members 300 is connected with base plate 400, and the lower end of multiple elastic members 300 is connected with the upper surface of floating block 200, and multiple elastic members 300 are used to push down floating block 200, so that probe 210 keeps in contact with product.
[0028] In the embodiment of the utility model, the strong current testing device further includes a rack, a driving manipulator and a testing and detecting module. The driving manipulator is arranged on the rack, the output end of the driving manipulator is connected with the substrate 400, and the driving manipulator is used for driving the substrate 400 to move in the up-down direction, the left-right direction and the front-back direction, so that the probe 210 can abut against the product to be tested. The testing and detecting module is electrically connected with the probe 210, and after the probe 210 abuts against the product, the testing and detecting module can obtain the strong current signal of the product, and thus the testing and detecting module can measure the strong current parameter of the product. The driving manipulator and the testing and detecting module are common settings in the field of strong current testing devices, and will not be further described here. In the embodiment of the utility model, the floating block 200 is made of insulating material, the probe 210 is a copper block, and the probe 210 is connected with the grounding cable 211. The grounding cable 211 is a common setting in the strong current testing device, and will not be further described here.
[0029] In the prior art, other running devices such as a circular vibration feeder often exist in the test environment. The vibration generated when these devices run can be transmitted to the product being tested through the ground or other supporting structures, causing the product to vibrate. After the product vibrates, the probe 210 in the existing strong current testing device will have a relative displacement between the probe 210 and the product to be tested, causing the contact to be intermittent, and thus the strong current testing device cannot continuously and stably obtain test data, thereby reducing the measurement accuracy of the strong current testing device. In the embodiment of the utility model, the elastic member 300 is a compression spring.
[0030] It can be understood that when the product needs to be tested for strong current, the floating block 200 is lowered, so that the probe 210 on the lower surface of the floating block 200 abuts against the product to be tested, and the plurality of elastic members 300 are all in a compressed state. After the plurality of elastic members 300 are all in a compressed state, the plurality of elastic members 300 can all push the floating block 200 downward, so that the probe 210 can press on the product, and thus the probe 210 can always abut against the product. Since the plurality of elastic members 300 are all telescopic, during the vibration of the product, the floating block 200 and the probe 210 can adaptively rise and fall according to the vibration of the product, so that the probe 210 can always abut against the vibrating product, avoiding the relative displacement between the probe 210 and the product, and thus ensuring the measurement accuracy of the strong current testing device.
[0031] Reference Figure 2 and Figure 3The strong current testing device further comprises a plurality of guide members 110 parallel to the up-down direction, a plurality of guide holes 220 are formed on the floating block 200, upper ends of the plurality of guide members 110 are connected with the base plate 400, lower ends of the plurality of guide members 110 are respectively arranged in the plurality of guide holes 220, and the plurality of elastic members 300 are respectively sleeved on the plurality of guide members 110. It can be understood that the lower ends of the plurality of guide members 110 are respectively arranged in the plurality of guide holes 220 on the floating block 200, the guide member 110 can abut against the hole wall of the guide hole 220, so that the floating block 200 and the probe 210 on the floating block 200 can move up and down stably.
[0032] With reference to Figure 3 The guide member 110 is a bolt, a threaded section of the bolt is threadedly connected with the base plate 400, and a large end of the bolt can abut against the lower surface of the floating block 200. In the embodiment of the utility model, when the probe 210 does not abut against the product, that is, when the probe 210 is located at the initial position, the plurality of elastic members 300 are all in the compressed state, at this time, the plurality of elastic members 300 push the floating block 200 downward, so that the lower surface of the floating block 200 is pressed on the large ends of the plurality of bolts. The large ends of the plurality of bolts limit the floating block 200, avoid the floating block 200 from being separated from the plurality of bolts due to the too long stroke of the floating block 200 moving downward, and ensure that the strong current testing device can normally operate. On the other hand, when it is necessary to adjust the initial position of the floating block 200 and the probe 210 according to different specifications of products, the operator can loosen or tighten the plurality of bolts, so that the large ends of the plurality of bolts are lowered or raised, and then the initial position of the floating block 200 and the probe 210 is lowered or raised, thereby improving the use flexibility of the strong current testing device. It needs to be explained that the threaded section of the bolt is the upper end of the bolt, and the large end of the bolt is the lower end of the bolt.
[0033] With reference to Figures 1 to 3The strong current test device further comprises a mounting seat 100 connected with the base plate 400, the floating block 200 is configured to be connected on the mounting seat 100 in a sliding manner along the up-down direction, and the upper ends of the plurality of elastic members 300 are connected with the mounting seat 100. In the embodiment of the utility model, the upper end of the guide piece 110 is connected with the mounting seat 100, that is, the upper ends of the plurality of bolts are threadedly connected with the mounting seat 100. The plurality of elastic members 300 are arranged between the mounting seat 100 and the floating block 200. A plurality of first limiting grooves 120 are formed on the lower surface of the mounting seat 100, the upper ends of the plurality of elastic members 300 are respectively connected with the inner bottom walls of the plurality of first limiting grooves 120, a plurality of second limiting grooves 230 are formed on the upper surface of the floating block 200, and the lower ends of the plurality of elastic members 300 are respectively connected with the inner bottom walls of the plurality of second limiting grooves 230. It can be understood that the upper ends of the plurality of elastic members 300 respectively extend into the plurality of first limiting grooves 120, the lower ends of the plurality of elastic members 300 respectively extend into the plurality of second limiting grooves 230, and the inner side walls of the first limiting grooves 120 and the second limiting grooves 230 limit the elastic members 300, so that the elastic members 300 can be smoothly stretched and contracted. Figure 3 In the embodiment of the utility model, the plurality of second limiting grooves 230 are respectively communicated with the plurality of guide holes 220.
[0034] Reference Figure 1 And Figure 2 The mounting seat 100 is detachably connected with the base plate 400, and the probe 210 is detachably connected with the floating block 200. It can be understood that when the corresponding probe 210 needs to be replaced for different products, the operator can first detach the mounting seat 100 from the base plate 400, and then detach the probe 210 from the floating block 200. After selecting a new probe 210, the operator re-installs the new probe 210 on the floating block 200, and then re-installs the mounting seat 100 on the base plate 400, so as to complete the replacement of the probe 210. As an embodiment of the utility model, the probe 210 can be detachably connected with the floating block 200 through a threaded fastener, which will not be described further.
[0035] Reference Figure 1 And Figure 2The strong current testing device further comprises a fixing assembly. The mounting base 100 is provided with an insertion plate 130, and the base plate 400 is formed with an insertion slot 410. The insertion plate 130 is arranged in the insertion slot 410. The fixing assembly is arranged on the base plate 400 and is used for fixing the insertion plate 130 in the insertion slot 410. It can be understood that when the mounting base 100 needs to be detached from the base plate 400, an operator can control the fixing assembly to release the insertion plate 130, and then the insertion plate 130 is pulled out of the insertion slot 410 on the base plate 400, so that the mounting base 100 is detached. When the mounting base 100 needs to be mounted on the base plate 400, the operator can insert the insertion plate 130 into the insertion slot 410 on the base plate 400, and then control the fixing assembly to fix the insertion plate 130, so that the insertion plate 130 is fixed in the insertion slot 410, and the mounting base 100 is mounted.
[0036] Reference Figure 1 and Figure 2 The fixing assembly comprises two knob plungers 420. The two knob plungers 420 are arranged on the base plate 400. The left and right sides of the insertion plate 130 are provided with clamping grooves. The pin columns of the two knob plungers 420 can be inserted into the two clamping grooves, so that the insertion plate 130 is fixed in the insertion slot 410. The knob plunger 420 is a common mechanical component. The knob plunger 420 is usually composed of a knob, a plunger body and a pin column. An operator can rotate the knob, so that the pin column is retracted or extended. It can be understood that when the mounting base 100 needs to be detached from the base plate 400, the operator can rotate the knobs on the two knob plungers 420, so that the pin columns on the two knob plungers 420 are retracted and pulled out of the two clamping grooves on the insertion plate 130. At this time, the insertion plate 130 is released, and the operator can pull out the insertion plate 130 from the insertion slot 410 on the base plate 400 to detach the mounting base 100. When the mounting base 100 needs to be mounted on the base plate 400, the operator can insert the insertion plate 130 into the insertion slot 410 on the base plate 400, so that the two clamping grooves on the insertion plate 130 are aligned with the two knob plungers 420. Then the operator can rotate the knobs on the two knob plungers 420, so that the pin columns on the two knob plungers 420 are extended and inserted into the two clamping grooves on the insertion plate 130, and the insertion plate 130 is fixed in the insertion slot 410 on the base plate 400, so that the mounting base 100 is mounted.
