Description

Technical Field

[0001] The invention relates to the technical field of current collecting tube bracket processing equipment, and in particular to automatic welding equipment for current collecting tube brackets. Background Art

[0002] The existing header bracket for heat exchangers is usually directly connected to the heat exchange flat tubes without any diversion measures. After entering the header bracket, the gas-liquid two-phase stratification phenomenon is obvious, resulting in uneven distribution of the refrigerant entering each heat exchange flat tube, and poor heat exchange performance of the heat exchanger. In recent years, the diversion technology of inserting the diversion tube in the header bracket has emerged to improve the heat exchange performance of the heat exchanger. This requires opening holes on the header bracket to weld the pipe socket for inserting the diversion tube. The existing technology usually welds the pipe socket manually with the help of tooling, and visually locates the welding through the assembly groove at one end of the header bracket. Because there is an error in visual positioning, the consistency of multiple pipe sockets on the same header bracket is poor, and the welding efficiency is relatively slow, affecting the welding efficiency and product quality. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an automatic welding device for a collector bracket to solve the technical problems of low welding consistency in the prior art.

[0006] The support seat forms a receiving surface for placing the workpiece to be processed, and the receiving surface is inclined so that the workpiece to be processed located on the receiving surface can move to the positioning device under the action of gravity;

[0007] The material blocking assembly is arranged at the end of the receiving surface close to the positioning device, and the material blocking assembly comprises a limiting column and a material blocking driving member for driving the limiting column to rise and fall, and when the material blocking driving member is extended, it drives the limiting column to rise and penetrate the receiving surface so that the workpiece being processed on the receiving surface remains stationary;

[0014] The conveying assembly includes a fixing portion and a transfer portion connected to the fixing portion;

[0015] The fixing part is used to fix the workpiece to be processed on the positioning assembly; the transfer part is used to drive the workpiece to be processed to move to the welding device;

[0016] The welding device comprises a welding execution assembly and a welding transmission assembly fixed on the bracket body;

[0017] The welding transmission assembly includes a welding fixing part and a welding transmission part, wherein the welding fixing part includes a clamping claw, and the clamping claw is used to clamp the workpiece to be processed on the conveying assembly; the welding transmission part is used to drive the welding fixing part to move toward the welding execution assembly or away from the welding execution assembly;

[0018] When the workpiece being processed moves to the welding execution assembly, the welding execution assembly welds the workpiece being processed.

[0019] Preferably, the support seat comprises a first support plate, a second support plate arranged parallel to the first support plate, and a loading guide rail slidably connected to the second support plate;

[0020] A loading rotary motion output device is fixedly installed on the end of the second support plate away from the first support plate through a loading bracket, and the output shaft of the loading rotary motion output device is fixedly connected to an adjusting screw rod, and the end of the adjusting screw rod away from the loading rotary motion output device is passed through the first support plate and is threadedly connected to the first support plate, and the loading rotary motion output device controls the adjusting screw rod to perform forward and reverse motions so that the supporting surface can retract or extend in the width direction to adapt to workpieces of different lengths.

[0021] The collecting tube bracket is set with different lengths according to different specifications. The combination of the feeding rotary motion output device and the adjusting screw can form the receiving surfaces of different widths according to the different lengths of the collecting tube bracket, which can facilitate the feeding of the collecting tube brackets of different lengths and improve the applicability of the present invention.

[0022] Preferably, the positioning structure comprises a first rotating axis and a second rotating axis arranged parallel to the first rotating axis, and rollers are symmetrically arranged on the first rotating axis and the second rotating axis to place the workpiece to be processed.

The plurality of adsorption plates are controlled by the same adsorption control signal so that the processed workpiece adsorbed by the adsorption plates can fall off the conveying assembly.

[0024] By adsorbing the collector bracket on the positioning assembly through the adsorption plate, the positioning position of the collector bracket will not be shifted due to shaking during transportation, thereby reducing the positioning error of welding. At the same time, the adsorption plate will not scratch the collector bracket during contact with the collector bracket, nor will it damage the coating on the surface of the collector bracket, thereby improving product quality during the welding process.

[0025] Preferably, the transfer unit comprises:

[0026] A cam seat, wherein a rotating shaft is passed through the cam seat, and a transfer track is arranged on the cam seat;

[0027] A first connecting rod, one end of which is fixedly connected to the rotating shaft;

[0032] Preferably, the transfer track includes a horizontal portion and vertical portions located at both ends of the horizontal portion, and the vertical portions located at both ends of the horizontal portion are located on the same side of the horizontal portion.

[0033] The design of the transfer track allows the workpiece on the positioning assembly to be first lifted vertically, then horizontally displaced, and then vertically placed on the welding device, which can reduce the contact between the positioned workpiece and the positioning assembly and the welding device, while reducing scratches on the collecting tube bracket during transportation, thereby ensuring product quality. At the same time, when the workpiece moves along such a transfer track, the first rotary power output device performs a reciprocating swinging motion of positive and negative 180 degrees, which is easy to control.

[0034] Preferably, the fixing part also includes a second conveying rod arranged parallel to the first conveying rod, and a plurality of the adsorption plates are evenly arranged on the second conveying rod, and when the first conveying rod adsorbs the workpiece to be processed on the positioning assembly, the second conveying rod can adsorb the workpiece to be processed on the welding base.

[0035] The addition of the second conveying rod can transfer the unwelded collecting tube bracket to the welding base while also taking the collecting tube bracket welded on the welding base and transferring it to the next process. The steps of taking the semi-finished products and transferring the finished products in the welding process are carried out simultaneously, which can improve the production rhythm and thus ensure production efficiency.

[0037] The diameters of the collecting tube brackets vary. During manual welding, it is necessary to replace the tooling according to the different diameters of the collecting tube brackets and then perform welding. The design of the clamping parts with different depths can make the present invention adapt to more different specifications of collecting tube brackets. The shallower the depth, the more suitable it is for collecting tube brackets with larger diameters, thereby improving the applicability of the present invention.

[0038] Preferably, a finished product conveyor belt is also arranged near the welding device. When the first conveying rod places the adsorbed workpiece to be processed on the welding base, the finished product conveyor belt can receive the workpiece to be processed placed on the second conveying rod and convey it.

[0039] The finished product conveyor belt is provided to receive the welded collecting pipe bracket from the second conveying rod and convey it to the next processing step, so that automatic unloading can be achieved without manual intervention, thereby reducing the labor intensity of the staff.

[0040] Preferably, the roller is a rubber wheel.

[0041] The design of the rubber wheel can reduce scratches on the collector bracket during the positioning process, thereby improving product quality.

[0042] The present invention discloses an automatic welding device for a collector bracket, which has low consistency compared with the manual welding in the prior art:

[0043] The present invention only requires manual feeding in the feeding device during the entire welding process, thereby improving the degree of automation of the present invention, saving labor costs and reducing the labor intensity of the staff; at the same time, the present invention greatly improves production efficiency;

[0044] The present invention collects images through an image acquisition device provided on a positioning component and finds the preset position of the assembly groove and accurately locates the welding position through an image processor. The image processor is configured with a first processing strategy and a corresponding first trigger condition to process image information. When the processed image information meets the first trigger condition, a positioning control signal is output according to the image to control the action of the positioning rotary motion output device. Compared with manual visual positioning, the positioning deviation is reduced and the consistency of the welding position of the pipe socket on the batch manifold bracket is improved.

[0045] The present invention adjusts the positioning welding position on the positioning assembly, which is convenient to operate, can reduce scratches caused by mutual contact during manual rotation positioning, and can improve the quality of the collector bracket.

[0059] The feeding device 2 includes a support base 21 and a material blocking assembly 22;

[0060] The support seat 21 forms a receiving surface for placing the workpiece to be processed, and the receiving surface is inclined so that the workpiece to be processed located on the receiving surface can move to the positioning device 3 under the action of gravity;

[0061] The inclination angle formed by the receiving surface and the horizontal angle can be set to 5 degrees, so that the collecting pipe bracket can slide on the receiving surface to the positioning device 3 relatively quickly under the action of gravity alone.

[0062] The material blocking assembly 22 is arranged at the end of the receiving surface close to the positioning device 3, referring to Figure 3 The material blocking assembly 22 includes a limiting column 221 and a material blocking driving member 222 for driving the limiting column 221 to rise and fall. When the material blocking driving member 222 is extended, it drives the limiting column 221 to lift and penetrate the receiving surface so that the workpiece being processed on the receiving surface remains stationary; when the material blocking driving member 222 is not working, the top of the limiting column 221 is lower than the receiving surface and will not hinder the sliding of the collecting tube bracket.

[0063] The material blocking driving member 222 may be a cylinder.

[0071] For example, the first processing strategy may be to scan the rotating collector bracket through the image acquisition device 313, and the movement position of the assembly slot preset in the image processor relative to the image acquisition device 313 is used as the first trigger condition. When the assembly slot on the collector bracket moves to the preset position, a positioning control signal is output to stop the positioning rotation motion outputter 312 from rotating.

[0072] Reference Figure 5 and Figure 6 , the conveying assembly 32 includes a fixing portion 321 and a transfer portion 322 connected to the fixing portion 321;

[0079] In the prior art, manual welding is usually used, which has the problems of low welding efficiency and low consistency of welding quality of pipe sockets in batch header brackets, and problems such as false welding and leaking welding emerge in an endless stream, which reduces the overall quality of the product and may affect the performance of the header bracket;

[0080] In the present invention, only the loading device 2 is required to manually load the header bracket during the entire welding process, which improves the automation level of the present invention, saves labor costs, reduces the labor intensity of the staff, avoids manual repetitive mechanical actions, and improves the welding efficiency. Furthermore, the welding execution component 41 replaces manual welding to ensure that the welding quality of each pipe socket is consistent, thereby improving product quality and product performance.

[0081] The present invention collects images through the image acquisition device 313 on the positioning component 31, finds the preset position of the assembly groove and accurately locates the welding position through the image processor, and the image processor is configured with a first processing strategy and a corresponding first trigger condition to process the image information, and when the processed image information meets the first trigger condition, the positioning rotation output device 312 is controlled to move according to the image output positioning control signal, compared with manual visual positioning, the positioning deviation is reduced, and the consistency of the welding position of the pipe socket on the batch manifold bracket is improved;

The output shaft of the loading rotary motion output device 215 is fixedly connected to an adjusting screw 216. The end of the adjusting screw 216 away from the loading rotary motion output device 215 is penetrated by the first support plate 211 and is threadedly connected to the first support plate 211. The loading rotary motion output device 215 controls the adjusting screw 216 to perform forward and reverse movements to allow the supporting surface to retract or extend in the width direction to adapt to workpieces of different lengths.

[0085] The collecting tube bracket is set with different lengths according to different specifications. The combination of the feeding rotary motion output device 215 and the adjustment screw can form receiving surfaces of different widths according to the different lengths of the collecting tube bracket, which can facilitate the feeding of collecting tube brackets of different lengths and improve the applicability of the present invention.

[0086] Preferably, refer to Figure 4 The positioning structure 311 includes a first rotating shaft 3111 and a second rotating shaft 3112 arranged parallel to the first rotating shaft 3111 . Rollers 3113 are symmetrically arranged on the first rotating shaft 3111 and the second rotating shaft 3112 to place the workpiece to be processed.

[0087] Specifically, the same positioning rotational motion output device 312 can drive the two rotating shafts to rotate in the same direction through pulleys and belts.

[0088] Preferably, refer to Figure 6 and Figure 7 The fixing part 321 includes a first conveying rod 3211, and a plurality of adsorption plates 3212 are evenly arranged at the end of the first conveying rod 3211 close to the positioning component 31. The adsorption plates 3212 are used to adsorb the workpiece being processed on the positioning component 31. The plurality of adsorption plates 3212 are controlled by an adsorption control signal generated by the same vacuum generator 3213 so that the workpiece being processed adsorbed by the adsorption plates 3212 can fall off from the conveying component 32.

[0089] By adsorbing the collector bracket on the positioning assembly 31 through the adsorption plate 3212, the positioning position of the collector bracket will not be shifted due to shaking during transportation, thereby reducing the positioning error of welding. At the same time, the adsorption plate 3212 will not scratch the collector bracket during contact with the collector bracket, nor will it damage the coating on the surface of the collector bracket, thereby improving product quality during the welding process.

[0099] The design of the transfer track 3223 allows the workpiece on the positioning component 31 to be lifted vertically first, then horizontally displaced and then placed vertically on the welding device 4, which can reduce the contact between the positioned workpiece and the positioning component 31 and the welding device 4, while reducing scratches on the collecting tube bracket during transportation, thereby ensuring product quality. At the same time, when the workpiece moves along such a transfer track 3223, the first rotary motion output device performs a reciprocating swinging motion of positive and negative 180 degrees, which is easy to control.

[0100] Preferably, refer to Figure 7The fixing part 321 also includes a second conveying rod 3214 arranged parallel to the first conveying rod 3211, and a plurality of adsorption plates 3212 are evenly arranged on the second conveying rod 3214. When the first conveying rod 3211 adsorbs the workpiece to be processed on the positioning assembly 31, the second conveying rod 3214 can adsorb the workpiece to be processed on the welding base 4212.

[0101] The addition of the second conveying rod 3214 can transfer the unwelded collecting tube bracket to the welding base 4212 while also taking the welded collecting tube bracket on the welding base 4212 and transferring it to the next process. The steps of taking the semi-finished products and transferring the finished products in the welding process are carried out simultaneously, which can improve the production rhythm and thus ensure production efficiency.

[0102] Preferably, refer to Figure 8 The clamping claw 4211 is an air claw. The clamping claw 4211 has a clamping structure that can adapt to workpieces of different diameters. The clamping structure includes a first clamping portion 42111, a second clamping portion 42112, a third clamping portion 42113, a fourth clamping portion 42114 and a fifth clamping portion 42115. The depth of the first clamping portion 42111 recessed into the clamping claw 4211 is greater than that of the second clamping portion 42112, the depth of the second clamping portion 42112 recessed into the clamping claw 4211 is greater than that of the third clamping portion 42113, the depth of the third clamping portion 42113 recessed into the clamping claw 4211 is greater than that of the fourth clamping portion 42114, and the depth of the fourth clamping portion 42114 recessed into the clamping claw 4211 is greater than that of the fifth clamping portion 42115.

[0103] The diameters of the collecting tube brackets vary. During manual welding, it is necessary to replace the tooling according to the different diameters of the collecting tube brackets and then perform welding. The design of the clamping parts with different depths can make the present invention adapt to more different specifications of collecting tube brackets. The shallower the depth, the more suitable it is for collecting tube brackets with larger diameters, thereby improving the applicability of the present invention.

[0104] Preferably, refer to Figure 1 and Figure 2 A finished product conveyor belt 5 is also provided near the welding device 4. When the first conveying rod 3211 places the adsorbed workpiece on the welding base 4212, the finished product conveyor belt 5 can receive the workpiece placed on the second conveying rod 3214 and convey it.

[0107] The design of the rubber wheel can reduce scratches on the manifold bracket during positioning and improve product quality.

[0108] All of the above-mentioned rotary motion output devices can be configured as servo motors.

[0109] During the working process, the material is manually loaded onto the support seat 21, and then the second support plate 212 is adjusted to adapt to the length of the collector bracket to be welded. When a collector bracket moves to the positioning component 31 due to gravity, the limit column 221 is lifted above the receiving surface under the drive of the material blocking drive 222, so that the collector brackets adjacent to and after the first one remain stationary. At the same time, the positioning rotation driver drives the collector bracket to rotate on the positioning component 31. When it rotates to the position required for welding, the image processor outputs a positioning control signal to stop the positioning rotation driver and maintain the current position. Then, the collector bracket on the positioning component is transferred to the welding fixing part through the adsorption disk 3212 on the first conveying rod 3211. 421, at the same time, the suction plate 3212 on the second conveying rod 3214 transfers the welded collecting tube bracket to the finished product conveyor belt 5 for transmission to the next process, and the collecting tube bracket to be welded is placed on the welding fixing part 421 and then the clamping claw 4211 firmly clamps the collecting tube bracket. At the same time, the welding rotational motion output device 4222 controls the welding fixing part 421 to approach the welding execution component 41 through a forward circuit, and when the collecting tube bracket moves to the welding execution component 41, the welding execution component 41 welds the collecting tube bracket. After the welding is completed, the welding rotational motion output device 4222 returns to the initial position through a reverse circuit control and continues to receive the collecting tube bracket on the first conveying rod 3211.
