the swing arm 5 switches direction and is connected to the first connecting member 3a or the second connecting member 3b to switch the printing direction.
Specifically, the base frame 1 can reciprocate along the horizontal direction, the first adjusting component 2a and the second adjusting component 2b are respectively arranged on two sides of the base frame 1, the first adjusting component 2a is connected with the first connecting component 3a, and the second adjusting component 2b is connected with the second connecting component 3 b. When printing reciprocally, due to the change of the printing direction, the matching direction of the scraper 6 on the screen needs to be switched, so that the conductive paste can be printed on the silicon chip when the scraper 6 reciprocates. For this purpose, the device switches the connection form of the oscillating arm 5 with the first connecting component 3a or with the second connecting component 3b according to the printing direction, so that the scraper 6 can drive the conductive paste to flow towards the movement direction of the scraper 6, so as to form a corresponding conductive structure on the silicon wafer. It should be noted that the matching angle between the scraper 6 and the screen can affect the printing quality, for this reason, the device can adjust the position of the first connecting component 3a along the vertical direction through the first adjusting component 2a, and can adjust the position of the second connecting component 3b along the vertical direction through the second adjusting component 2b, so as to adjust the matching angle between the swing arm 5 and the first connecting component 3a and the second connecting component 3b, so as to adjust the matching angle between the scraper 6 and the screen, and thus, the conductive paste can be uniformly printed on the silicon wafer.
As a first embodiment of the first adjusting assembly 2a and the second adjusting assembly 2b, the first adjusting assembly 2a and the second adjusting assembly 2b each include an adjusting screw 21 connected to the base frame 1. Specifically, by adjusting the screwing depth of the adjusting screw 21 and the base frame 1, the position of the scraper 6 along the vertical direction can be changed, so that the swing angle of the swing arm 5 is changed, and the matching angle of the scraper 6 and the silk screen is correspondingly changed.

When the scraper 6 moves from right to left to the leftmost position, the second electromagnetic part 31b is powered off, the scraper 6 is lifted up, the electric rotating shaft 4 drives the swing arm 5 to rotate, the first electromagnetic part 31a is powered on, the swing arm 5 and the first electromagnetic part 31a are tightly attracted, and the scraper 6 is reset.
In order to improve the attraction surface of the electromagnetic member 31 and the swing arm 5, the swing arm 5 is stably attracted. The electromagnetic part 31 is provided with an inclined surface contact electromagnetic block 311 matched with the brush head.
Referring to fig. 3, it should be noted that when the first and second adjusting members 2a and 2b move in the vertical direction to change the position of the electromagnetic member 31, the inclination angle of the inclined surface contact electromagnetic block 311 is not changed, so that the swing arm 5 cannot be completely attached. To solve this problem, the electromagnetic member 31 further includes a mounting case 312 connected to the first adjusting assembly 2a or the second adjusting assembly 2 b; the mounting housing 312 is made of a non-magnetic material, and the inclined surface contact electromagnet block 311 can rotate relative to the mounting housing 312. Specifically, a hinge shaft 313 is provided between the electromagnetic member 31 and the mounting housing, and the electromagnetic member 31 can be completely attracted to the swing arm 5 by rotating the electromagnetic member 31 relative to the mounting housing 312, so as to improve the connection reliability between the swing arm 5 and the electromagnetic member 31.
