Description

Technical Field

[0001] The invention relates to a heat dissipation fin welding technology, and in particular to a welding processing device for a fin-type radiator. Background Art

[0002] The fin-type heat sink is a commonly used heat dissipation and cooling component in the inverter field, usually consisting of a base plate and several fins.

[0003] Welding is an essential step in the production process of fin-type heat sinks, and the most commonly used welding method is manual welding, and some welding robots are also used for welding. When manual welding is used for welding, it not only lacks precise positioning, but is also prone to inefficiency and welding position deviation during the welding process, resulting in insufficient welding quality. When welding is performed by a welding robot, the feeding robot grabs the heat sink fins one by one and places them in the appropriate position on the substrate. After placement, the heat sink fins are continued to be clamped to ensure the stability of the fins during the welding process, which makes the welding of a set of fin-type heat sinks take a long time, resulting in an increase in the welding processing cost of the fin-type heat sink. Summary of the Invention

[0004] The object of the present invention is to provide a welding processing device for a fin-type radiator to solve the above-mentioned deficiencies in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: A welding processing device for a fin-type heat sink, comprising a base, a rotating table rotatably provided on the base, the rotating table being driven by a motor, the motor driving the rotating table to rotate intermittently, and the rotating table rotating at a single angle of 90°; The outside of the base is circularly provided with a substrate robotic arm, a gear robotic arm, a welding robotic arm and a blanking robotic arm in sequence, and the rotating table is circumferentially and equidistantly provided with a substrate loading station, a gear loading station, a welding station and a blanking station; The substrate loading station, the gear loading station, the welding station and the unloading station are all provided with a carrying unit, and the substrate and the gear are carried on the carrying unit.

[0006] Furthermore, the positions of the substrate robot arm, the gear robot arm, the welding robot arm and the unloading robot arm correspond to the substrate loading station, the gear loading station, the welding station and the unloading station respectively.

[0007] Furthermore, the supporting unit includes a supporting seat installed on the surface of the rotating table, a supporting groove is provided on the upper surface of the supporting seat, and connecting plates are installed on the surface of the rotating table symmetrically distributed on both sides of the supporting seat, and a plurality of support bars are installed at equal distances along the length direction on the surfaces of the connecting plates facing each other on both sides, and positioning grooves are provided at the ends of the support bars.

[0008] Furthermore, the shape and specifications of the bearing groove are adapted to the base plate, the shape and size specifications of the positioning groove are adapted to the tooth plate, and the distance between the positioning grooves on both sides away from the inner wall of one side is adapted to the length value of the tooth plate.

[0009] Furthermore, the surface of the rotating table is equipped with guide bars symmetrically distributed on both sides of the bearing seat, the surface of the guide bar is provided with a guide groove, the inner side of the guide groove is slidably connected to a guide block, and the top of the guide block is equipped with a support frame.

[0010] Furthermore, the connecting plate is fixedly connected to the top of the side of the support frame, and the position height of the support bar is adapted to the tooth plate. When the tooth plate is supported on the surface of the base plate, the top surface of the support bar is flush with the top surface of the tooth plate.

[0011] Furthermore, the surface of the rotating table is rotatably connected to a synchronous gear, the outside of the support frames on both sides are fixedly connected to synchronous rods, the outsides of the two synchronous rods are fixedly connected to synchronous racks, and the surface of the rotating table is installed with an electric telescopic rod corresponding to the synchronous rack.

[0012] Furthermore, the two synchronous racks are respectively engaged with the two sides of the synchronous gear, and the telescopic end of the electric telescopic rod is fixedly connected to one of the synchronous racks.

[0013] Compared with the prior art, the welding processing device for a fin-type radiator provided by the present invention has the following beneficial effects: 1. The welding processing device of the tooth-fin type radiator can stably load, assemble and weld the tooth-fin type radiator during the welding process through the mutual cooperation between the rotating table, the base plate robot arm, the tooth-fin robot arm, the welding machine robot arm, the unloading robot arm and the carrying unit, thereby making the welding process of the tooth-fin type radiator more convenient and efficient.

[0014] 2. The welding processing device of the gear-type radiator adjusts the workstation position through intermittent rotation of the rotary table, so that the carrying units in different states move to different robot arm positions. This not only allows the welding work of the radiator to continue, but also makes the structure of the welding processing device more compact and occupies less space, which is conducive to reducing the welding processing cost of the radiator.

[0015] 3. The welding processing device of the tooth-type radiator can stably support and limit the tooth-plate during welding through the mutual cooperation of the connecting plate, the support bar and the positioning groove. Moreover, the mutual cooperation between the support frame, the synchronous gear, the synchronous rack and the electric telescopic rod can adjust the distance between the support bars on both sides when needed, which not only facilitates the loading of the substrate, but also does not hinder the removal of the workpiece after welding is completed, which is conducive to the smooth progress of the radiator welding work.

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Example 1: See also Figure 1-Figure 5A welding processing device for a fin-type radiator includes a base 1, a rotating table 2 is rotatably provided on the base 1, the rotating table 2 is driven by a motor, the motor drives the rotating table 2 to rotate intermittently, and the rotating table 2 rotates 90 degrees in a single rotation angle; The base 1 is provided with a substrate robot arm 3, a gear robot arm 31, a welding robot arm 32 and a blanking robot arm 33 in a circular shape. The rotating table 2 is provided with a substrate loading station 34, a gear loading station 35, a welding station 36 and a blanking station 37 in a circular shape at equal intervals. The substrate loading station 34 , the gear loading station 35 , the welding station 36 and the unloading station 37 are all provided with a carrying unit 4 , and the substrate 5 and the gear 6 are carried on the carrying unit 4 .

[0021] It should be noted that the positions of the substrate robot arm 3 , the gear robot arm 31 , the welding robot arm 32 and the unloading robot arm 33 correspond to the substrate loading station 34 , the gear loading station 35 , the welding station 36 and the unloading station 37 respectively.

[0022] The specific structure of the carrying unit 4 is described below. The carrying unit 4 includes a carrying seat 41 installed on the surface of the turntable 2. The upper surface of the carrying seat 41 is provided with a carrying groove 42. The surface of the turntable 2 is provided with connecting plates 43 symmetrically distributed on both sides of the carrying seat 41. A plurality of support bars 44 are installed at equal distances along the length direction of the surfaces of the connecting plates 43 facing each other on both sides. The ends of the support bars 44 are provided with positioning grooves 45.

[0023] It should be noted that the shape and specifications of the bearing groove 42 are compatible with the base plate 5, the shape and size specifications of the positioning groove 45 are compatible with the tooth plate 6, and the distance between the positioning grooves 45 on both sides away from the inner wall of one side is compatible with the length value of the tooth plate 6, so that under the coordinated positioning effect of the positioning grooves 45 on both sides, the tooth plate 6 is assembled with higher accuracy, thereby improving the subsequent welding quality.

[0024] During operation, the substrate 5 in the peripheral storage unit is grabbed by the substrate robot arm 3 and placed in the supporting slot 42 at the substrate loading station 34. When the turntable 2 rotates, the supporting seat 41 with the substrate 5 is rotated to the corresponding position of the tooth robot arm 31. At this time, the tooth 6 in the peripheral storage unit is grabbed by the tooth robot arm 31 and placed in the corresponding positioning slot 45, so that the bottom of the tooth 6 abuts against the surface of the substrate 5. Afterwards, the turntable 2 rotates again, so that the supporting seat 41 with the substrate 5 and the tooth 6 is rotated to the welding robot arm 32, so that the welding robot arm 32 can weld the assembled tooth 6 and the substrate 5, so that the tooth 6 can be stably welded and fixed on the surface of the substrate 5. Afterwards, the turntable 2 rotates again, so that the substrate 5 and the tooth 6 after welding are rotated to the unloading robot arm 33, so that the unloading robot arm 33 can remove the workpiece after welding.

[0025] Example 2: See also Figure 4-Figure 5 This embodiment provides a technical solution based on the above embodiment: the surface of the rotating table 2 is equipped with guide bars 7 symmetrically distributed on both sides of the bearing seat 41, and the surface of the guide bar 7 is provided with a guide groove 71. The inner side surface of the guide groove 71 is slidably connected with a guide block 72, and the top of the guide block 72 is equipped with a support frame 73.

[0026] It should be noted that the connecting plate 43 is fixedly connected to the top of the side of the support frame 73, and the position height of the support bar 44 is adapted to the tooth piece 6. When the tooth piece 6 is supported on the surface of the substrate 5, the top surface of the support bar 44 is flush with the top surface of the tooth piece 6, and the distance between two adjacent tooth pieces is greater than four times the support bar 44, so that after the tooth piece 6 is assembled, the positioning groove 45 can not only stably limit the position of the tooth piece 6, but also make the spacing between two adjacent support bars 44 meet the needs of the welding robot arm 32 for welding the tooth piece 6.

[0027] It should be further added that the surface of the rotating table 2 is rotatably connected to a synchronization gear 74, the outside of the support frames 73 on both sides are fixedly connected to synchronization rods 75, the outsides of the two synchronization rods 75 are fixedly connected to synchronization racks 76, and the surface of the rotating table 2 is installed with an electric telescopic rod 77 corresponding to the synchronization racks 76.

[0028] Furthermore, two synchronous racks 76 are respectively engaged with the two sides of the synchronous gear 74 , and the telescopic end of the electric telescopic rod 77 is fixedly connected to one of the synchronous racks 76 .

[0029] During operation, when the welded workpiece moves to the unloading robot arm 33, the electric telescopic rod 77 drives one of the synchronous racks 76 to move, so that under the transmission of the synchronous gear 74, the two synchronous racks 76 can move synchronously in opposite directions and drive the support frames 73 on both sides to move away from each other. When the support frame 73 moves, it drives the connecting plate 43 and the support bar 44 to move, so that the support bar 44 can be separated from the gear piece 6. After that, the unloading robot arm 33 removes the welded workpiece; When the supporting seat 41 that has just removed the workpiece rotates to the substrate robot 3 along with the rotating table 2, the substrate robot 3 places the substrate 5 in the supporting groove 42 on the supporting seat 41. After the substrate 5 is placed, the electric telescopic rod 77 drives the support bars 44 on both sides to move synchronously in opposite directions, so that the distance value between the positioning grooves 45 on both sides can meet the needs of placing the tooth plate 6.

[0030] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
