Problems solved by technology
[0009] However, in the above-mentioned conventional situation, the manufacturing cost of the filler with nozzle as an additional part added to the supplied paste pot is high, and it is necessary to remove the filler with nozzle from the used paste pot, clean and reinstall it. There is a problem of low operating efficiency due to the back-and-forth operation of the additional parts for the new paste pot

Provided are: a paste supply apparatus that is more cost-effective easier to operate; and a screen printer, paste supply method, and screen printing method using said paste supply apparatus. The paste supply apparatus is provided with a paste pot (51), a pot holding part (52), and a pot pressing cylinder (53). The paste pot (51) is provided with: a bottomed cylindrical member (61) for accommodating a paste; for example, solder paste; and a center lid (62) movably inserted into the cylindrical member (61), a through-hole (63) being formed in the central portion of the center lid (62). The pot holding part (52) holds the paste pot (51) in a position in which the through-hole (63) faces downward. The pot pressing cylinder (53) causes the cylindrical member (61) to move relative to the center lid (62) of the paste pot (51), which is held by the pot holding part (52), causing an action in which paste is extruded from the through-hole (63).
Description
technical field [0001] The present invention relates to a paste supply device for supplying paste to a mask in contact with a substrate in a screen printer, a screen printer, a paste supply method, and a screen printing method. Background technique [0002] Conventionally, in a screen printing machine, as a paste supply device for supplying paste to a mask in contact with a substrate, there is known a device for extruding and supplying paste onto a mask from a syringe storing paste (for example, Patent Document 1). There is also known a paste supply device in which the paste stored in the syringe is supplied in a state sealed in a closed container composed of a bottomed cylindrical member called a paste pot and a middle cap inserted into the cylindrical member. , but instead of moving the paste from the paste pot to the syringe, the paste pot itself is used as a syringe (for example, Patent Document 2). [0003] In the latter paste supply device, as a preparation in advance...
