The discharge end of the outer cap material conveying channel 13 can be positioned above the tin heating device 18, and a point injection position, a tin conveying position and a gasket position are sequentially limited on the path from the outer cap feeding device 12 to the tin heating device 18 by the outer cap material conveying channel 13. The free ends of the soldering flux spot pouring device 15, the tin feeding and cutting device 16 and the gasket feeding device 17 are respectively suspended above the spot pouring position, the tin feeding position and the gasket position of the outer cap material conveying channel 13. The discharge end of the heated tin melting device 18 can be connected with the outer cap discharging device 14. The outer cap sent out by the outer cap feeding device 12 passes through the positions below the scaling powder spot injection device 15, the tin feeding and cutting device 16 and the gasket feeding device 17 along the outer cap feeding channel 13 in sequence, and is sent into the tin heating device 18 to be processed in sequence, so that the scaling powder, the tin wires and the gaskets are added in sequence in the outer cap, the outer cap is manufactured through heating treatment, and the outer cap is sent to the outer cap discharging device 14 through the tin heating device 18.

The output shaft of the driving device 22 can be connected with the soldering flux dispensing device 15, the tin conveying and cutting device 16 and the gasket conveying device 17, so as to drive the soldering flux dispensing device 15, the tin conveying and cutting device 16 and the gasket conveying device 17 to move simultaneously, so that the device 1 can synchronously add soldering flux, tin wires and gaskets at the dispensing position, the tin conveying position and the gasket position of the outer cap material conveying channel 13, the structure is simple, the action is efficient, and the cost of the device 1 can be reduced.

Specifically, the control device controls the starting of the outer cap feeding device 12 and controls the supply speed of the outer cap feeding device 12, so that the outer caps are fed to the outer cap feeding channel 13. When the outer cap moves to the position below the free end of the soldering flux dispensing device 15, the control device controls the control valve of the soldering flux dispensing device 15 to be opened to add soldering flux into the outer cap, and then when the outer cap reaches the position below the free end of the tin feeding and cutting device 16, the control device controls the tin feeding and cutting device 16 to be started to add tin wires into the outer cap. When the outer cap reaches below the free end of the gasket feeding device 17, the control device controls the gasket feeding device 17 to start to add the gasket in the outer cap. It can be understood that when three or more outer caps are processed, the flux dispensing device 15, the tin feeding and cutting device 16 and the pad feeding device 17 can synchronously operate under the driving of the driving device 22 to perform three operations, thereby greatly improving the production efficiency of the outer caps. The outer cap moves along the outer cap feeding channel 13 until the outer cap moves away from the outer cap feeding channel 13 to reach the feeding end of the tin heating device 18, the control device controls the tin heating device 18 to heat the outer cap, the periphery of the molten tin wire can wrap the gasket after heating, and the gasket of the obtained outer cap is not easy to fall off. Finally the outer cap reaches the outer cap discharge 14 and the control means controls the outer cap discharge 14 to start and move the outer cap to the storage means.

In the third motion state, the four movable stoppers 191 move away from the outer cap feed passage 13 in the left-right direction to release the outer caps gripped by the respective movable stoppers 191. In the fourth motion state, the taking mechanism 20, the buffer mechanism 21, and the four movable positioners 191 are all returned to the initial positions in the first motion state in the front-rear direction to perform the first motion state again, and thus to reciprocate.
