Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a tester for the electrical performance of a motor terminal block assembly. Background Technology

[0002] The Booster brushless motors used in new energy vehicles require low voltage, high torque, small size, and light weight. Therefore, the motor wiring must be stable, compact, well-insulated, reliable, and resistant to shock and vibration. Consequently, a terminal block assembly (or terminal block support assembly, lead wire fixing structure) is typically used to uniformly fix the multiple wires on the motor. This terminal block assembly has multiple terminals, and their electrical performance must be guaranteed. For example, the insulation resistance, insulation withstand voltage, and leakage current of each terminal must meet the required standards. This necessitates testing each terminal individually on the terminal block assembly. Currently, this is usually done manually with testing equipment, which is inefficient and costly.

[0029] The testing mechanism includes a test frame 31, a test head 32 and a test drive cylinder 33 mounted on the test frame. The test frame is fixedly mounted on the machine base. The test head is mounted on the end of the push rod of the test drive cylinder. One end of the test head is connected to the testing instrument. The testing instrument is prior art and is not within the protection scope of this utility model, so it will not be described in detail.

[0030] The marking mechanism 4 includes a marking frame 41, a marker pen 42 mounted on the marking frame, and a marking drive cylinder 43. The marking frame is fixedly mounted on the machine base, and the marker pen is mounted on the end of the push rod of the marking drive cylinder.

[0031] The turntable is a rotating turntable.

[0032] In this embodiment, the fixture is a transparent insulating material block, and the fixture is detachably connected to the turntable. In this embodiment, each fixture has two product slots, allowing for simultaneous electrical performance testing of two products.

[0033] In this embodiment, a rotary drive mechanism 5 is connected to the bottom of the turntable, which drives the turntable to rotate. The rotary drive mechanism is prior art and will not be described in detail.

[0034] In this embodiment, the test head 32 includes a test disk 321 and a test block 322. Both the test disk and the test block are provided with multiple detection pins 3211. The detection pins on the test block can correspond one-to-one with the three-phase terminals 201 on the product, and the detection pins on the test disk can correspond one-to-one with the ordinary terminals 202 on the product. This allows for simultaneous testing of the electrical performance of both the three-phase terminals and the ordinary terminals of the product.

[0035] In this embodiment, a mounting block 44 is fixed to the end of the push rod of the marking drive cylinder. The mounting block has a longitudinally extending mounting hole, and the upper end of the marker is inserted into the mounting hole and fixedly connected to the mounting block. This structure makes it easy to replace the marker with a new one after it is used up.

[0036] In this embodiment, the testing machine is covered by a protective shell 6.

[0037] In this embodiment, two start switches 11 are provided on the side of the machine platform closest to the operator, located on the left and right sides respectively.

If the above requirements are met, the product is qualified. If any terminal does not meet the above requirements, the product is unqualified and needs to be marked for subsequent rework. During rework, the specific terminal that is unqualified will be determined by instruments and then repaired.

[0041] The working principle and process of this utility model:

[0042] The operator places the product to be tested into the product slot of the fixture at the loading / unloading station and presses the start button. The fixture and product rotate with the turntable to the testing station. The test drive cylinder drives the test head and the detection head mounted on it to descend and perform electrical performance tests on each terminal. After the test is completed, the electrical performance test results are transmitted to the control system of the testing machine (the structure and working principle of the control system are not within the protection scope of this utility model, so they will not be described in detail). The fixture and product continue to rotate with the turntable to the marking station. If the product's electrical performance is qualified, the marking mechanism does not operate; if the product's electrical performance is unqualified, the marking drive cylinder drives the marker pen to descend and mark the product. Afterward, the fixture and product rotate with the turntable to the loading / unloading station, where the tested products are classified as qualified and unqualified and placed. Then, the above process is repeated.

[0043] The above description is merely an embodiment of the present utility model and does not limit the patent scope of the present utility model.
