Description

Technical Field

[0001] The utility model relates to the technical field of insulation impedance testing, in particular to an automatic insulation impedance testing device. Background Art

[0002] In the 3C (computer, communication and consumer electronics) industry, such as mobile phones and tablet computers, insulation impedance testing refers to the process of testing and evaluating the insulation performance of equipment. Insulation impedance refers to the ability of insulating materials in electronic equipment to block current, that is, the non-conductivity of insulating materials to current. The main purpose of insulation impedance testing is to ensure that the insulation performance of the equipment meets the relevant standards and specifications, and to ensure that there is no electrical short circuit or electric shock hazard during normal operation of the equipment.

[0003] In the industry, manual testing or semi-automatic testing is generally used. In manual testing, testers use multimeters and insulation testers to manually test products. Testers need to follow the test process and instructions, observe the oscilloscope readings or indicator light status, and record the test results. Semi-automatic testing combines machine operation and manual operation. Usually, testers use automated test equipment and software to perform tests, while the preparation of test operations and equipment connection need to be done manually. The test instrument control software will automatically perform the test and record the test results. Whether it is manual testing or semi-automatic testing, the participation of testers is required, the labor cost is high, and the manual operation steps need to be repeated during batch testing. The work content is boring and has certain requirements for manual skills, and the accuracy and stability of the test cannot be ensured. Utility Model Content

[0030] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0031] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0033] See also Figures 1 to 11 , is an automatic insulation impedance testing device according to an embodiment of the present invention, comprising a conveying component 10, at least one testing component 20 installed on one side of the conveying component 10, and a verification component 30 installed on one side of each testing component 20.

[0034] The conveying assembly 10 includes a product conveyor belt 11, a lifting module 12 installed on the product conveyor belt 11, a blocking cylinder 13 installed on opposite sides of the lifting module 12, a blocking block 14 connected to the top of the blocking cylinder 13, and a return conveyor belt 15 arranged parallel to the lower side of the product conveyor belt 11. The product conveyor belt 11 is used to convey a loaded pallet 40, on which a product 41 to be tested is carried; the return conveyor belt 15 is used to convey an empty pallet 40; the blocking cylinder 13 is used to drive the blocking block 14 to rise to abut against the side of the pallet 40, so that the lifting module 12 can lift the pallet 40.

[0035] In this embodiment, the lifting module 12 includes a lifting frame 121 slidably connected to the inside of the product conveyor belt 11, a support block 122 connected to the inner walls on both sides of the lifting frame 121, and a lifting cylinder 123 fixedly connected to the bottom of the product conveyor belt 11; wherein the support block 122 is used to abut the tray 40, the cylinder body of the lifting cylinder 123 is fixedly connected to the product conveyor belt 11, and the piston rod of the lifting cylinder 123 is connected to the top of the lifting frame 121 to drive the lifting frame 121 to move vertically, thereby lifting the tray 40, so as to facilitate the subsequent test assembly 20 to perform insulation impedance testing.

[0036] Furthermore, in the present embodiment, the lifting frame 121 is substantially U-shaped, and the outer walls on opposite sides of the lifting frame 121 are slidably connected to the product conveyor belt 11 through guide rail pairs 124 .

[0037] Furthermore, in the present embodiment, the lifting module 12 also includes a height limiting plate 125 respectively connected to the outside of the two opposite sides of the product conveyor belt 11, and the height limiting plate 125 is roughly arranged in a "7" shape. The top of the limiting plate 125 is used to abut the top of the lifting frame 121 to limit the lifting height range of the lifting frame 121.

[0038] In this embodiment, the conveying direction of the product conveyor belt 11 is opposite to the conveying direction of the return conveyor belt 15 .

[0039] The test assembly 20 includes a three-axis manipulator 21 installed on one side of the product conveyor belt 11, a carrier 22 installed at the end of the three-axis manipulator 21, buffer blocks 23 elastically installed at opposite ends of the bottom surface of the carrier 22, and a plurality of test probes 24 installed on the carrier 22; the buffer blocks 23 are used to elastically abut the tray 40, and the test probes 24 are used to abut the test points of the product to be tested 41 to achieve electrical connection for impedance testing. The number and position of the test probes 24 can be determined according to the actual product structure to be tested.

[0040] Furthermore, in actual use, the test efficiency can be improved by setting multiple test components 20. For example, Figure 1 and Figure 2 As shown, there are four test assemblies 20, of which two test assemblies 20 are for the first test process, and the other two test assemblies 20 are for the second test process. Insulation impedance tests can be performed on different positions of the product 41 to be tested, greatly improving the test efficiency.

[0041] The verification component 30 includes a vacuum fixture 31 installed on one side of the three-axis manipulator 21, and a standard product 32 detachably installed on the vacuum fixture 31. The standard product 32 here refers to a product that has been tested and met the standards. When testing products in large quantities, the three-axis manipulator 21 can periodically drive the test probe 24 to contact the test point of the standard product 32 for spot inspection. If the device alarms, it means that the test probe 24 is abnormal and needs to be manually replaced with a new test probe 24, which can effectively avoid the abnormality of the test probe 24 and cause errors in the test results or even damage to the product. Compared with traditional manual testing or semi-automatic testing, the automatic insulation impedance testing device of the utility model saves manual labor, greatly improves the degree of automation, and effectively ensures the accuracy and stability of the test.

[0042] When the test is completed, the tested products are taken away by a robot or manually, and the empty tray 40 is transferred to the return conveyor belt 15 to return the empty tray 40 to the loading position for use in the next test.

[0043] The above-mentioned automatic insulation impedance testing device has a reasonable structure and is easy to use. After the product 41 to be tested is transported to the location by the conveying assembly 10, the lifting cylinder module 12 lifts the product 41 to be tested, and the three-axis manipulator 21 drives the test probe 24 to fall and reach the product 41 to be tested for insulation impedance testing, which saves manual labor, greatly improves the degree of automation, and effectively ensures the accuracy and stability of the test.

[0044] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
