Description

Technical Field

[0001] This invention relates to the field of electronic device packaging technology, and more specifically, to a fully automatic capping machine. Background Technology

[0002] In existing electrical products, the sockets and caps of electronic components require encapsulation, and this encapsulation and welding process necessitates a capping machine. The socket and cap are placed on a copper base (lower electrode) on the capping machine, and then the upper and lower electrodes are used. The upper electrode descends to complete the resistance welding process for encapsulating the socket and cap. However, in existing capping machines, the sockets and caps can only be transferred sequentially to the lower electrode for sealing before the upper electrode descends for the welding operation. Only after the sealing is complete and the encapsulated socket and cap are removed from the lower electrode can the next socket and cap be encapsulated. This process has a very low level of automation and low efficiency, making it difficult to meet the demands of high-efficiency production. Summary of the Invention

A third torsion spring is provided at the hinge between the third push-pull plate and the cap tray 29, and the third push-pull plate corresponds to the electromagnetic chuck 8 of the cap transfer component 60. When the two sides of the third push-pull plate are not under attraction, the third torsion spring makes the third push-pull plate perpendicular to the cap tray 29. When the electromagnetic chuck 8 of the cap transfer component 60 is not energized and is not magnetic, the electromagnetic chuck 8 can push past the third push-pull plate and fold towards the cap tray 29, causing the slide table 10 to slide from one side of the cap tray 29 to the other side.

[0075] The electrode transmission component on the cap includes a seventh transmission wheel 51 and a fifth transmission belt 52. The seventh transmission wheel 51 is fixedly mounted on the second transmission shaft 30, and the two seventh transmission wheels 51 correspond one-to-one with the two second transmission shafts 30.

The fourth support base 53 is disposed on the top surface of the housing 59 and is sleeved on the electrode transmission component of the cap. The tube cap sliding fastener is slidably disposed on the fourth support base 53.

[0077] The tube cap sliding fastener includes a fourth slide block 54 and an upper electrode component. The fourth slide block 54 is C-shaped and is horizontally slidably fastened to the bottom surface of the fourth support base 53. One side of the fourth slide block 54 is connected to the side of the fifth transmission belt 52, so that the fourth slide block 54 slides on the bottom surface of the fourth support base 53 as the fifth transmission belt 52 rotates.

[0078] The upper electrode component includes a cap pressure support 55, a magnetic coil, a cap pressure transmission rod 56, an upper electrode 57, and a third spring 58. The cap pressure support 55 is a thick-walled tubular structure, with one end vertically fixed to the bottom surface of the fourth slide block 54. The magnetic coil is fixedly embedded in a spiral groove on the inner wall of the cap pressure support 55. One end of the cap pressure transmission rod 56 is axially slidably embedded in the other end of the cap pressure support 55, and the sliding groove on the cap pressure transmission rod 56 engages with a sliding block on the inner wall of the cap pressure support 55. The upper electrode 57 is cylindrical, with its top surface fixedly mounted on the bottom end of the cap pressure transmission rod 56. A cap hole is provided on the bottom surface of the upper electrode 57, the diameter of which is larger than the outer diameter of the cap, to facilitate current transmission when the cap is fitted onto the cap, thereby resistively sealing the cap 61 onto the tube seat 62.

[0079] The operation process of the fully automatic cap sealing machine is as follows:

[0080] 1) After the tube seat tray 13 and the tube cap tray 29 are pushed to the predetermined position, the motor 40 starts to drive the first drive shaft 14 and the second drive shaft 30 to rotate, and the first automatic gripper 20 and the second automatic gripper 36 respectively clamp the tube seat 62 and the tube cap 61;

[0081] 2) While the motor 40 is continuously running, the clamped tube seat 62 and tube cap 61 are simultaneously transferred to the lower electrode seat 50 at the same position; the first automatic gripper 20 and the second automatic gripper 36 begin to descend, allowing the tube seat 62 to be placed into the encapsulation hole, after which the first automatic gripper 20 fully opens; then the tube cap 61 is fitted onto the tube seat 62, and the second automatic gripper 36 fully opens; at the same time, the DC current supplied to the magnetic coil is stopped, and the upper electrode 57, pushed by the third spring 58, passes through the first automatic gripper 20 and the second automatic gripper 36, causing the tube cap hole to fasten onto the tube cap 61; then, after positive DC current is supplied to the magnetic coil to generate a magnetic field, the tube cap pressure transmission rod 56 is pushed to drive the upper electrode 57 to apply pressure to the tube cap 61, thereby increasing the fastening pressure between the tube cap 61 and the tube seat 62; at the same time, welding current is input to the upper electrode 57, causing the tube cap 61 and the tube seat 62 to be resistively welded together;

[0082] 3) As the motor 40 continues to start, during the sealing process of the cap 61 and the base 62, the upper electrode 57 and the lower electrode move synchronously. After the sealing time reaches the predetermined time, a reverse DC current is passed to the magnetic coil to generate a magnetic field, and the upper electrode 57 is pulled up. At this time, as the upper electrode 57 and the lower electrode are continuously driven, they move horizontally. After the cap 61 and the base 62, which are resistively sealed together, are moved to the right by the lower electrode to the predetermined position, they are pushed out from below by high-pressure gas, so that the cap 61 and the base 62, which are resistively sealed together, are separated from the encapsulation hole, thus completing one sealing operation of the cap 61 and the base 62.

[0083] 4) As the motor 40 continues to start, the remaining caps 61 and the bases 62 will continuously complete resistance sealing operations on the cyclically moving upper electrode 57 and the lower electrode. This significantly improves the automation, continuity, and efficiency of the sealing between the bases 62 and the caps 61.
