[0002] The static contact of the circuit breaker is usually made of metal copper. During the processing and manufacturing process of the static contact of the circuit breaker, the silver point is usually processed in advance and fixed on the contact surface of the static contact. This can be achieved through a variety of methods, such as welding, riveting, etc. Among them, welding is a common and effective method, which can firmly connect the silver point and the static contact to ensure that it will not fall off or loosen during use.

[0003] Conventional spot welding equipment for static contact processing requires workers to first dock and fix the static contact and the silver point, and then add welding auxiliary materials before starting operation. The degree of automation is low. For example, the spot welding machine for welding static contacts described in application number 202010617155.5 does not require the addition of welding auxiliary materials, which improves welding efficiency, but still requires manual placement of static contacts.

[0025] The present invention also discloses a method for using a high-efficiency welding device for processing circuit breaker contacts, which specifically comprises the following steps:

[0026] S1. Pre-assemble the static contact, insert the static contact into the assembly frame, reserve a length of the static contact beyond the assembly frame according to the size of the silver sheet to be welded, and tighten the fastening bolts to complete the pre-assembly of the static contact;

[0027] S2. Push the counterweight adjustment column upward, and the counterweight adjustment column drives the L-shaped clamping plate to separate from the adjustment plate. Hold the adjustment plate, so that the adjustment plate drives the assembly plate to rotate downward, and place the static contact clamping module with the static contact pre-assembled in the first groove. During the process, the docking plate is placed in the first groove, and the positioning hole is sleeved on the positioning cone. The extrusion plate is rotated so that the extrusion plate falls on one side of the docking plate, and the assembly of the static contact clamping module is completed.

[0028] S3. Rotate the adjustment plate. After the adjustment plate drives the assembly plate to rotate 180° around the rotating shaft, the assembly plate drives the static contact clamping module to be set downward, lift the adjustment plate upward, and push the counterweight adjustment column upward. After the adjustment plate enters the card slot, release the counterweight adjustment column, so that the L-shaped card plate is stuck at the bottom of the adjustment plate, and the adjustment plate is fixed again;

[0029] S4, control the electric telescopic rod to extend, the electric telescopic rod pushes the pressing plate to move the first tooth plate downward, the first tooth plate drives the tooth roller to rotate, the tooth roller drives the second tooth plate to move upward, the four second tooth plates drive the seat plate with holes to move upward, the seat plate with holes drives the pressing head to move upward, and the static contact is grooved;

[0030] S5. After the groove is pressed, the electric telescopic rod is controlled to retract and reset, and then several silver sheets are stacked and placed in the storage cylinder, and the silver sheet at the bottom falls into the barrel;

[0031] S6, repeat the S2-S4 operation. When the electric telescopic rod is extended, the static contact groove that has completed the groove pressing is set upward. When the four first tooth plates drive the four tooth rollers to rotate, the two tooth rollers drive the two male tooth plates to move closer to the female tooth plate, and the remaining two tooth rollers drive the two female tooth plates to move closer to the male tooth plate. During the process, the two guide plates drive a collaborative plate to move, the collaborative plate drives the slider to move in the slide groove, and the slider drives the loading plate to push the bottom silver sheet to move in the barrel;

[0032] When the silver sheet is about to move to the movable opening, the guide plate squeezes the second spring, and then as the silver sheet continues to move, the silver sheet passes through the movable opening and falls into the groove of the static contact after pressing. The upper electrode driven by the pressing plate has not yet entered the movable opening. When the feeding plate is about to move to the movable opening, the tooth parts of the male tooth plate and the female tooth plate are both separated from the tooth roller. As the electric telescopic rod continues to extend, the pressing plate drives the upper electrode to pass through the movable opening and closely contact the top of the silver sheet in the static contact groove. At this time, the pressing head performs groove pressing on the static contact in the static contact clamping module set downward. At this time, the upper electrode, the silver sheet, the static contact and the lower electrode conduct electricity to weld the silver sheet to the static contact.

[0033] During the movement of the loading plate, the first spring is reset, pushing the limit block to drive the slide bar to move, and the slide bar drives the L-shaped plug plate to move in the barrel to limit the bottom of the stacked silver sheets;

[0034] S7. After the silver sheet welding is completed, the electric telescopic rod is controlled to retract and reset. During the process, the tooth roller reverses, and the second spring resets and pushes the guide plate, so that the guide plate pulls the male tooth plate and the female tooth plate to engage with the tooth roller again. The tooth roller drives the male tooth plate and the female tooth plate to move, so that the guide plate drives the cooperation plate to reset the feeding plate. During the process, the feeding plate squeezes the L-shaped plug plate, and the L-shaped plug plate drives the slide bar to make the limit block compress the first spring. At this time, the silver sheet at the bottom of the storage barrel falls into the barrel;

[0035] S8. Push the counterweight adjustment column upwards, and the counterweight adjustment column drives the L-shaped clamping plate to detach from the adjustment plate. Hold the adjustment plate, so that the adjustment plate drives the assembly plate to rotate downward, rotate the extrusion plate to detach from the docking plate, and take out the static contact clamping module that has completed the silver sheet welding.

[0036] The present invention provides a high-efficiency welding device for processing circuit breaker contacts and a method for using the same. The device has the following beneficial effects:

[0037] (1) The present invention realizes the groove pressing processing of the static contact, the automatic loading of the silver sheet, and the welding and fixing of the silver sheet by a single power drive mode through the cooperation of the lifting drive component, the pressing processing component and the silver sheet feeding component. While the processing efficiency is high, under the setting of two contact processing components, on the basis of improving the stability of the device during operation, double-station processing is realized, and the welding processing efficiency of the static contact is further improved. In addition, through the groove pressing processing of the static contact, a precise positioning space is provided for the silver sheet to ensure the uniformity of the silver sheet welding position, so as to realize the efficient and stable welding processing of the static contact and effectively ensure the finished product quality of the static contact.

[0038] (2) The present invention realizes multi-angle and multi-directional rotation of the assembly plate by cooperating with the rotating bar, the rotating shaft, the assembly plate and the adjusting plate, and cooperates with the arrangement of the card slot, the L-shaped card plate, the linkage plate and the counterweight adjustment column to ensure the stability of the position of the assembly plate by limiting the adjusting plate, thereby providing convenience for the processing of the static contact in the static contact clamping module. At the same time, under the interaction force of the upper electrode squeezing the silver sheet and the pressing head pressing the groove on the static contact, the stability of the device during the processing is ensured, and the service life of the device is effectively guaranteed.

Tighten the fastening bolt 6034 to complete the pre-assembly of the static contact 6033.

[0075] S2. Push the counterweight adjustment column 6010 upwards, and the counterweight adjustment column 6010 drives the L-shaped clamping plate 608 to separate from the adjustment plate 606. Hold the adjustment plate 606, so that the adjustment plate 606 drives the assembly plate 602 to rotate downward, and place the static contact clamping module 603 pre-assembled with the static contact 6033 in the first groove 6035. During the process, the docking plate 6031 is placed in the first groove 6035, and the positioning hole 6038 is sleeved on the positioning cone 6037. The extrusion plate 6039 is rotated so that the extrusion plate 6039 falls on one side of the docking plate 6031, and the assembly of the static contact clamping module 603 is completed.

[0076] S3, rotate the adjustment plate 606, and after the adjustment plate 606 drives the assembly plate 602 to rotate 180° around the rotation axis 6011, the assembly plate 602 drives the static contact clamping module 603 to be set downward, lift the adjustment plate 606 upward, and move the counterweight adjustment column 6010 upward. After the adjustment plate 606 enters the clamping slot 607, release the counterweight adjustment column 6010, and after the L-shaped clamping plate 608 is clamped at the bottom of the adjustment plate 606, the adjustment plate 606 is fixed again;

During the process, the feeding plate 706 squeezes the L-shaped plug plate 7095, and the L-shaped plug plate 7095 drives the slide bar 7092 to make the limit block 7093 compress the first spring 7094. At this time, the silver sheet 703 at the bottom of the storage cylinder 702 falls into the cylinder 701;

[0083] S8. Push the counterweight adjustment column 6010 upwards, and the counterweight adjustment column 6010 drives the L-shaped clamping plate 608 to separate from the adjustment plate 606. Hold the adjustment plate 606, so that the adjustment plate 606 drives the assembly plate 602 to rotate downward, rotate the extrusion plate 6039, so that the extrusion plate 6039 is separated from the docking plate 6031, and take out the static contact clamping module 603 that has completed the welding of the silver sheet 703.
