Description

TECHNICAL FIELD

[0001] The present application relates to the field of welding equipment manufacturing, in particular to a welding device with automatic cutting and pushing functions and a control method. BACKGROUND

[0002] In order to improve production efficiency, automatic production equipment is generally used to improve production efficiency, and the same is true in the field of welding, that is, two products to be welded are first prepared into independent finished products by stamping equipment, and then sent to the welding equipment for welding.

[0003] However, the existing welding method requires high-precision jigs for positioning, and the upper product to be welded needs to be positioned by vacuum suction and suspended during upper and lower welding, that is, the two products to be welded are positioned in the jigs, and the two jigs need to be aligned, otherwise the welded product is difficult to meet the required size and is prone to deviation. In addition, the electrode is prone to misalignment during welding, which makes it difficult to stably butt joint the product. More importantly, the existing method of placing each product to be welded in the jig and tool independently is extremely low in efficiency and difficult to automate, and manual placement is required. Especially in the case of small-sized products to be welded, such as sensor contacts, contacts or other small metal conductive parts, the size is less than 2mm, which is difficult to hold with hands. Only by using tweezers to pick up can the product be picked up. This method is difficult to observe with the naked eye and difficult to operate. Even if it can be picked up, it takes a lot of time to prepare. Moreover, the existing welding equipment is large in size, different positioning jigs of different sizes and shapes need to be installed for different products, which has poor applicability and is difficult to meet the production demand.

[0004] In summary, the existing welding device still needs to be further improved and enhanced. SUMMARY

[0061] The cutting assembly 5 (see Figures 1-3 , 9-10) is used to cut the welding piece A1 from the cutting position and push it to the position corresponding to the side pushing assembly 6;

[0065] The supporting structure 54 and the unlocking piece 55 are arranged on the first swing rod 51 and located between the shearing block 53 and the support shaft 52;

[0072] In addition, a stop block 531 is formed on one side of the shearing block 53 opposite the side pushing assembly 6, which is used to limit the excessive displacement of the side pushing piece 63 when pushing the welding piece A1, and is accurately located on the lower electrode D1;

[0074] (see Figures 1-14 ) After each component is assembled, the driving assembly 3 is debugged to make the above components can be synchronized and linked, and can not interfere with each other, as follows:

[0075] (1) After the upper driving gear 311 is sleeved on the output shaft 310 of the motor 31 and arranged on the base 1, the encoder 9 is synchronously arranged on the base 1, and the motor 31 or the driving gear 311 is connected to obtain the rotation angle;

[0076] (2) The two axial cams 33C, 33D and the two circumferential cams 33A, 33B are respectively arranged on the main shaft 32 which is detachably fixed; before being arranged and fixed, the angle setting of each cam 33A, 33B, 33C, 33D is needed, that is, the setting is performed through the following control method:

[0077] The start positions of the pushing, cutting, side pushing and lifting welding actions are arranged in the four demarcated areas C (i.e. the cross section of the main shaft 32 is projected as a whole circle, and the demarcated areas C are the areas between 0-360 degrees in the projected area, i.e. 0-90°, 90°-180°, 180°-270° and 270°-360°) demarcated in the circle. The angle range is arranged after the time length of a complete welding process is deducted from the time length of the welding (for example, the time length of the whole process from pushing to welding is artificially set as 500 ms, 0-360°=500 ms in a cycle (i.e. one rotation), and the welding time length is about 180 ms, so the angle range is 100°, and the total angle of the actions is 260° after the angle of 100° required by the welding time length is deducted). Then the angles of the actions in the corresponding demarcated areas C are arranged (i.e. the start positions of the actions are arranged in the range of 260°, and the start positions are arranged in the corresponding demarcated areas C respectively; for example, the angle transformation process of the main shaft 32 in one rotation is as follows: the pushing is performed in the range of 0-90°, the pushing action of the continuous strip-shaped workpiece A1 starts at 5°, and the workpiece A1 is sent to the position at 80°. At this time, the cutting assembly 5 and the side pushing assembly 6 are in a standby state (i.e. not stopped at the position of the cam projection) in the angle range of 5-80°. Then, when the main shaft 32 rotates to the position of 80°, the cutting assembly 5 acts to cut the workpiece A1. The angle transformation in this process is completed in the range of 80-150°, and the workpiece A1 is continuously held to 290°. In this range, the cutting block 53 and the side pushing assembly 6 are kept in the same position to push the cut workpiece A1. At the same time, the pushing assembly 4 gradually returns to the original state to wait for the next clamping. Then, the main shaft 32 continues to rotate, and the pushing starts at 155° and is completed at 220°. Finally, the lifting assembly starts to lift the cut workpiece A1 at 230°, and the welding starts at 285°. The cycle is repeated in this way).

[0078] (3) After the angles are calculated, the cams 33A, 33B, 33C and 33D are fixed to the main shaft 32, the main shaft 32 is installed in the bearing seat of the base 1, and a driven gear 321 is installed in the end of the main shaft 32 close to the motor 31. Then, the driving gear 311 is engaged with the driven gear 321.

[0079] (4) The upper rollers 8 are installed at the ends of the first sliding rod 41, the second sliding rod 61, the first swing rod 51 and the second swing rod 71, and are arranged corresponding to the cams 33A, 33B, 33C and 33D respectively. The cams 33A, 33B, 33C and 33D are always in contact with the rollers 8.

[0080] The control method of the actual welding is as follows:
