[0014] Please see Figure 1-6The present invention relates to a nickel sheet insulation withstand voltage continuity vibration welding test fixture, comprising: a base plate 1, a testing mechanism on the top of the base plate 1, the testing mechanism being used to facilitate full inspection of the nickel sheet welding quality, ensuring the electrical safety and reliability of the product; the testing mechanism including left and right side support plates 2 and a core fixing plate 3; the left and right side support plates 2 being located on the top of the base plate 1 and vertically fixed to the left and right sides of the base plate 1; the core fixing plate 3 being installed on the top of the base plate 1; a download platform 4 being installed on the top of the core fixing plate 3; the download platform 4 being horizontally fixed in the middle of the top of the core fixing plate 3; a positioning pin 10 being installed on the top of the download platform 4; and an upper loading platform 5 being installed on the top of the positioning pin 10. The loading stage 5 is stacked on top of the download stage 4. A probe mounting plate 6 is installed on the top of the loading stage 5. An observation window 7 is installed on the top of the base plate 1, located in front of the left and right side support plates 2. A top cover plate 8 is located on top of the left and right side support plates 2 and is horizontally fixed to the top of the left and right side support plates 2. Side cover plates 9 are installed on the outer walls of the left and right side support plates 2 and are vertically fixed to the outer walls of the left and right side support plates 2. The base plate 1 is made of black bakelite with a thickness of 6mm, the left and right side support plates 2 are made of bakelite with a thickness of 10mm, the download stage 4 is made of FR4 epoxy resin glass cloth with a thickness of 12mm, and the loading stage 5 is made of F... The base plate 1 is made of R4 epoxy resin glass cloth, 10mm thick. The probe fixing plate 6 is made of green FR4 polished plate, 10mm thick. The observation window 7 is made of acrylic, 10mm thick. The top cover plate 8 and side cover plate 9 are both made of black bakelite, 10mm thick. The base plate 1 is placed horizontally on the workbench, ensuring a flat surface (checked with a level, error ≤ 0.1mm). The base plate 1 serves as the foundation of the fixture. The high strength of the black bakelite (Brind hardness ≥ 100HB) ensures long-term use without deformation. The left and right side support plates 2 are vertically fixed to the left and right edges of the base plate 1, forming a U-shaped frame. The bakelite provides insulation. (Volume resistivity > 10¹³ Ω·cm) can isolate external interference and prevent test voltage leakage. The core fixing plate 3 is horizontally fixed to the top center of the base plate 1 as the base of the download stage 4. The download stage 4 is horizontally locked to the top center of the core fixing plate 3. The download stage 4 is a precise positioning carrier for the nickel sheet. The surface is ground (flatness Ra ≤ 0.1 μm) and has a custom groove pre-processed to match the contour of the nickel sheet to ensure that the welding points correspond one-to-one with the test probes. The positioning pin 10 is inserted into the positioning hole on the top of the download stage 4. The upper platform 5 is stacked on top of the download stage 4 and precisely aligned by the positioning pin 10 to ensure that the coaxiality error of the grooves of the upper platform 5 and the download stage 4 is ≤ 0.The upper stage 5, with a diameter of 0.02mm, is also ground and pre-machined with probe guide holes to guide the probe to make vertical contact with the nickel sheet. The probe fixing plate 6 is horizontally locked to the top of the upper stage 5. The probe fixing plate 6 is a precise guide carrier for the test probe. Its surface is machined with a dense array of small holes, the positions of which correspond perfectly with the test points (such as positive and negative poles, insulation detection positions) on the nickel sheet. After the probe passes through the small holes, it makes precise contact with the nickel sheet through the guide holes of the upper stage 5. The observation window 7 is fixed in front of the left and right support plates 2 and locked with screws. The transparency of the acrylic (light transmittance > 90%) facilitates observation of the internal nickel sheet condition and isolates dust and moisture. The top cover plate 8 is horizontally fixed. The left and right support plates 2 are fixed to the top and secured with screws to seal the top of the fixture and prevent dust from entering from above. The side cover plates 9 are vertically fixed to the outer wall (non-operating side) of the left and right support plates 2 and secured with screws to seal the sides of the fixture, enhancing overall rigidity. Custom slots and holes restrict the position of the nickel sheet, ensuring that the relative positional error between the nickel sheet and the probe during testing is ≤0.05mm. A small hole array guides the probe to perpendicularly contact the nickel sheet test point, avoiding test failures caused by probe misalignment (such as misjudging a cold solder joint during continuity testing). The high insulation of FR4 prevents high-voltage testing (such as AC1000V) from leaking to other parts of the fixture, ensuring test safety and accuracy.

[0015] Working principle: Place the base plate 1 horizontally on the workbench, ensuring the bottom surface is flat. The base plate 1 serves as the foundation of the fixture. Vertically fix the left and right support plates 2 to the left and right edges of the base plate 1. Horizontally fix the core fixing plate 3 to the top center of the base plate 1 as the base of the download platform 4. Horizontally lock the download platform 4 to the top center of the core fixing plate 3. The download platform 4 is a precise positioning carrier for the nickel sheet. Insert the positioning pin 10 into the positioning hole at the top of the download platform 4. Stack the upper platform 5 on top of the download platform 4 and align it precisely using the positioning pin 10. Horizontally lock the probe fixing plate 6 to the top of the upper platform 5. Fix the observation window 7 in front of the left and right support plates 2. Horizontally fix the top cover plate 8 to the top of the left and right support plates 2. Vertically fix the side cover plate 9 to the outer wall (non-operating side) of the left and right support plates 2. Tighten with screws to seal the sides of the fixture and assemble the fixture.
