Further, the side surface of the support base 1 is provided with an air receiving port 11 for communicating with a vacuum generator, and the air receiving port 11 communicates with the first air passage 12. The first air passage 12 may be disposed at the top of the support base 1, and the air receiving port 11 may be in communication with the first air passage 12 through a pipe. In actual use, vacuum generation is initiated to draw air from the first air passage 12, so that a negative pressure is formed in the first air passage 12.

The adsorption plate 2 is detachably arranged on the support base 1, and a second air passage 23 is arranged on the adsorption plate 2; when the adsorption plate 2 is arranged on the support base 1, the second air passage 23 is communicated with the first air passage 12; the adsorption plate 2 is provided with a plurality of support positions, and the support positions are provided with air holes 22 communicated with the second air passages 23. Since the second air passage 23 is communicated with the first air passage 12, when negative pressure is formed in the first air passage 12, negative pressure is also formed at the supporting position, so that the product placed on the supporting position can be adsorbed, and the solder paste printer can print solder paste on the product.

The supporting device comprises a supporting base 1 and an adsorption plate 2, wherein a first air passage 12 is formed in the supporting base 1, the adsorption plate 2 is detachably arranged on the supporting base 1, and a second air passage 23 is formed in the adsorption plate 2. When the adsorption plate 2 is disposed on the support base 1, the second air passage 23 communicates with the first air passage 12. The adsorption plate 2 is provided with a plurality of support positions, and air holes 22 communicated with the second air passages 23 are arranged in the support positions. Because the adsorption plate 2 is detachably arranged on the support base 1, the adsorption plate can be replaced according to production requirements in practical application, and the application range of the support device is widened. And the adsorption plate 2 is communicated with the support base 1 through the air passage, so that the gas flow area is large, the vacuum adsorption capacity of the adsorption plate 2 is high, the risk of product falling and shifting during production can be greatly reduced, and the production efficiency is improved.
