The conductive silver paste is poured onto the top of the coating table 11, and the scraper 16 evenly coats the conductive silver paste on the top of the coating table 11. Through the above structure, the setting of turning the fine adjustment knob 15 to move the scraper 16 closer to or further away from the coating table 11 is formed, forming an adjustable coating structure.

Silicon guide plates are installed on the side wall of the guide plate 32 near the baffle plate 33. The silicone strip pulls the baffle plate 33 to slide on the inner wall of the hopper 3. The silicone strip contacts the baffle plate 33 and presses the baffle plate 33 against the inner wall of the hopper 3, thereby adjusting the opening size of the outlet 31. The conductive silver paste flows out from the outlet 31 and falls onto the top of the coating table 11. Through the above structure, the sliding baffle plate 33 adjusts the opening size of the outlet 31, forming a feeding speed adjustment structure, realizing the function of adjusting the feeding speed control of conductive silver paste and improving the convenience of controlling the feeding speed of conductive silver paste.

[0030] like Figure 2 As shown, the bottom of the testing platform 1 is fixedly connected with rubber feet 6. Multiple sets of rubber feet 6 are set at the bottom of the testing platform 1 and are evenly distributed at the four corners of the bottom of the testing platform 1. During operation, after the testing platform 1 is placed in the working area, the box 5 contacts the working area, increasing the friction between the testing platform 1 and the working area, reducing the deviation of the testing platform 1 during operation, and improving the stability of the testing platform 1 during operation.

[0031] During operation, the conductive silver paste to be tested is placed into the feeding assembly.

The screw 14 then moves the scraper 16, which slides along the inner wall of the scraper rack 12. The distance between the bottom of the scraper 16 and the coating table 11 is adjusted. The scraper rack 12 is then moved on top of the coating table 11 by the coating moving assembly. Conductive silver paste is poured onto the top of the coating table 11, and the scraper 16 evenly coats the conductive silver paste on top of the coating table 11. The servo motor 21 is then started, driving a set of lead screws 22 to rotate. The lead screws 22, through gears inside the gearbox 24, drive another... A set of lead screws 22 rotates, driving a pair of sliding frames 23 to move in the middle of the testing table 1. The sliding frames 23 drive the scraper frame 12 to move evenly on the side wall of the coating table 11, making the coating of conductive silver paste by the scraper 16 more uniform. The conductive silver paste to be tested is placed into the hopper 3. A silicone strip is installed on the side wall of the guide plate 32 near the baffle plate 33. Pulling the baffle plate 33 to slide on the inner side wall of the hopper 3, the silicone strip contacts the baffle plate 33 and squeezes the baffle plate 33 against the inner side wall of the hopper 3, thereby adjusting the opening size of the outlet 31. The conductive silver paste flows out from the outlet 31. After the conductive silver paste is coated on the top of the coating table 11, the bracket 4 is rotated to bring the baking lamp 41 close to the top of the coating table 11.
