Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and in particular to a capacitor lead welding device. Background Art

[0002] The lead welding of a capacitor is to weld and fix the lead on the metallized surface of the capacitor core, which is a very important process in the capacitor manufacturing process; The prior art also proposes a solution for the lead welding of capacitors. For example, a Chinese patent with the publication number CN207489684U discloses a capacitor lead welding device, which includes a support frame, a lifting mechanism installed on the support frame, and an operating table connected to the lifting end of the lifting mechanism. Among them, slide rails are vertically arranged on both sides of the support frame, and the operating table moves along the direction of the slide rails. The lifting mechanism includes a connecting steel wire rope, a fixed pulley group, and a driving part. The driving part is used to control the tensioning and relaxation of the connecting steel wire rope. This technical solution can adjust the height of the operating table according to capacitors of different heights, facilitating the welding operation.

[0003] Although the above technical solution can adjust the height of the operating table according to capacitors of different heights, there are still other problems in actual use. For example, during the lead welding process, it is necessary to align the lead with the capacitor and then weld it on the surface of the capacitor. However, since the lead is small and light, it is rather troublesome to align it with the capacitor, which affects the welding of the two.

[0004] Therefore, a capacitor lead welding device is proposed to solve the above problems. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides a capacitor lead welding device, which includes a lead welding table. Above the lead welding table, a bearing turntable is rotatably arranged. Above the bearing turntable, multiple groups of annular frames are arranged. The multiple groups of annular frames are designed in a circumferential array above the bearing turntable. Above each group of annular frames, a placement frame plate one is arranged. Inside the placement frame plate one, a capacitor body to be welded is placed. Above the lead welding table, a placement frame plate two is installed through a bracket. Inside the placement frame plate two, a lead body is placed. The placement frame plate one and the placement frame plate two are designed on the same horizontal plane. Above the lead welding table, a welding head and a welding wire are installed through a bracket.

[0006] In one embodiment of the present invention, contact rods are installed on the side walls of each set of the placement frame plates one. Above the lead welding table, a rectangular plate is provided through a bracket. Below the rectangular plate, a contact rod is provided. During the process of the bearing round table driving the annular frame and the contact rods to rotate, the contact rods will contact the contact bars. During operation, when the bearing round table drives one set of the placement frame plates one to rotate, it will simultaneously drive the contact rods to rotate. When the contact rods contact the contact bars during rotation, the external circuit is connected at this time. The external controller will first control the bearing round table to stop rotating. If the lead body and the capacitor body are in contact with each other at this time, the external controller will continue to control the welding head to weld the welding wire to the contact part of the lead body and the capacitor body.

[0007] In one embodiment of the present invention, a reciprocating cylinder one is provided above the lead welding table. The telescopic end of the reciprocating cylinder one is connected to the side wall of the rectangular plate. Two fitting tubes are installed on the side wall of the rectangular plate away from the reciprocating cylinder one. The two fitting tubes and the placement frame plates two are designed on the same horizontal plane. The inner diameter of the fitting tube is larger than the diameter of the lead body. During operation, when the contact rods and the contact bars are in contact, if the lead body and the capacitor body are not in contact at this time and the bearing round table is in a stopped state at this time, then the external controller will control the telescopic end of the reciprocating cylinder one to move, so that its telescopic end drives the rectangular plate to move. The rectangular plate will drive the fitting tubes to move. Then the fitting tubes will move to the outside of the lead body, and the lead body will penetrate into the inside of the fitting tubes. Subsequently, the fitting tubes will drive the lead body to move towards the side close to the capacitor body, that is, the lead body will contact the capacitor body. In this way, it is convenient for welding the two, and it has the function of automatic docking.

[0008] In one embodiment of the present invention, the shape of the fitting tube is large in diameter at one end and small in diameter at the other end. The inner diameter of the fitting tube at the small-diameter end is smaller than the diameter of the lead body. During operation, when the lead body extends into the inside of the fitting tube, due to the design of the shape of the fitting tube itself, the lead body will be embedded in the end with a smaller diameter of the fitting tube. In this way, the fitting tube will drive the lead body to move towards the side close to the capacitor body, which is convenient for the subsequent combination of the two, and solves the problem that in the prior art, it is necessary for the staff to manually dock and then weld, and the operation is relatively convenient.

[0009] In one embodiment of the present invention, a rotating disk is rotatably provided above the bearing round table. The side wall of the rotating disk is connected to the output end of the motor. The motor is installed inside the bearing round table. The side wall of the rotating disk is connected to the side wall of the annular frame through a recycling unit. The recycling unit is used to recycle the welded capacitors. Above the lead welding table, a blocking frame is installed. A rotating round wheel is rotatably provided on the side wall of the blocking frame. The side wall of the rotating round wheel is connected to the side wall of the reciprocating cylinder one through a cross shaft.

[0010] In an embodiment of the present invention, a plurality of limiting ring frames are installed on the side wall of the bearing frustum. The annular frame is rotatably arranged inside the limiting ring frame, and a groove adapted to the annular frame is arranged in the limiting ring frame. During operation, the arrangement of the limiting ring frame facilitates the rotation of the annular frame, thereby facilitating the rotation of the capacitor body.

[0011] In an embodiment of the present invention, the recovery unit includes a reciprocating cylinder II. The end of the reciprocating cylinder II is connected to the side wall of the rotating disc. A connecting frame is installed at the telescopic end of the reciprocating cylinder II. A frame-shaped frame is installed above the annular frame. The end of the connecting frame away from the reciprocating cylinder II is connected to the placement frame plate I. A limiting column frame is installed above the bearing frustum, and the end of the limiting column frame contacts the side wall of the capacitor body.

[0012] In an embodiment of the present invention, a limiting column plate is installed below the placement frame plate I. The limiting column plate is slidably arranged in the frame-shaped frame. A groove adapted to the limiting column plate is opened in the frame-shaped frame. The end of the connecting frame is connected to the side wall of the limiting column plate. During operation, when the connecting frame moves, the connecting frame will simultaneously pull the limiting column plate and the placement frame plate I away from the capacitor, thus facilitating the recovery of the capacitor. Moreover, with the mutual limitation between the limiting column plate and the frame-shaped frame, it is convenient for the annular frame to drive the placement frame plate I and the capacitor body to rotate.

[0013] In an embodiment of the present invention, two folding plates are rotatably installed on the end face of the placement frame plate I. The two folding plates are used to fix the capacitor body. An electric column is installed on the side wall of the placement frame plate I. The telescopic end of the electric column is hinged to the side wall of the folding plate. During operation, when the capacitor body is placed inside the placement frame plate, by controlling the telescopic end of the electric column to drive the folding plate to rotate, the two folding plates on both sides are pressed against the outer wall of the capacitor body, which plays a certain clamping role on the capacitor body. Thus, it is convenient for the subsequent annular frame to drive the placement frame plate I and the capacitor body to rotate, so that the capacitor body will not fall off.

[0014] In an embodiment of the present invention, the folding plate is made of rubber, and friction lines are arranged on the inner wall of the folding plate.

[0015] The above technical solution of the present invention has the following advantages compared with the prior art: For the capacitor lead welding device of the present invention, by controlling the movement of the telescopic end of the reciprocating cylinder I, the telescopic end drives the rectangular plate to move. The rectangular plate drives the fitting tube to move. Then the fitting tube moves to the outside of the lead body, and the lead body penetrates into the fitting tube. Subsequently, the fitting tube drives the lead body to move towards the side close to the capacitor body, that is, the lead body contacts the capacitor body, thus facilitating the welding of the two and achieving the function of automatic docking.

[0016] For a capacitor lead welding device according to the present invention, since the end of the limit post frame contacts the side wall of the capacitor body, when the placement frame plate 1 moves, the capacitor body will not move under the limit, that is, the placement frame plate 1 will move away from the bottom of the capacitor body. When the placement frame plate 1 completely leaves the bottom of the capacitor body, the welded capacitor will fall into the recovery seat below under its own gravity. With such a design, the lead welding device of the present invention can not only continuously weld capacitors, but also automatically recover the welded capacitors, improving the welding efficiency of capacitors.

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and be able to implement it, but the embodiments cited do not limit the present invention.

[0021] Referring Figures 1 to 4 As shown, a capacitor lead welding device according to an embodiment of the present invention includes a lead welding table 1. Above the lead welding table 1, a bearing turntable 2 is rotatably provided. Above the bearing turntable 2, a plurality of annular frames 3 are provided. The plurality of annular frames 3 are designed in a circumferential array above the bearing turntable 2. Above each annular frame 3, a placement frame plate 301 is provided. Inside the placement frame plate 301, a capacitor body 4 to be welded is placed. Above the lead welding table 1, a placement frame plate 101 is installed through a bracket. Inside the placement frame plate 101, a lead body 5 is placed. The placement frame plate 301 and the placement frame plate 101 are designed on the same horizontal plane. Above the lead welding table 1, a welding head 6 and a welding wire 7 are installed through a bracket; During operation, it should be noted that the welding head 6 and the welding wire 7 mentioned in the embodiment of the present invention are both controlled by an external hydraulic system, that is, the external hydraulic system can control the welding head 6 and the welding wire 7 to move towards the contact position close to the lead body 5 and the capacitor terminal 4. The control method of the hydraulic system and the welding method of the welding head 6 are both prior arts and will not be described in detail in the embodiment of the present invention; Referring to the attached Figure 1 and Figure 3 As shown, a capacitor body 4 is placed inside each placement frame plate 301. The bearing turntable 2 is controlled to rotate through an external controller, so that the bearing turntable 2 drives one of the placement frame plates 301 to move towards the side close to the placement frame plate 101. When one of the placement frame plates 301 and the placement frame plate 101 move to the same horizontal plane, the rotation of the bearing turntable 2 is stopped. At this time, the capacitor body 4 and the lead body 5 also come into contact with each other. Then, the lead body 5 can be welded to the surface of the capacitor body 4 through the welding head 6. After one group of capacitor bodies 4 is welded, through the continuous rotation of the bearing turntable 2, the next group of capacitor bodies 4 can be welded. With such a design, the lead and the capacitor can be welded continuously, and since the placement frame plate 301 and the placement frame plate 101 are designed on the same horizontal plane, the docking effect between the lead and the capacitor is good, solving the problem in the prior art that it is difficult to dock the lead with the capacitor due to the small size and light weight of the lead.

[0022] It should be noted that the lower end surface of the bearing turntable 2 is connected to the output end of the motor.

[0023] A contact rod 8 is installed on the side wall of each placement frame plate 301. Above the lead welding table 1, a rectangular plate 9 is arranged through a bracket. Below the rectangular plate 9, a contact rod 10 is arranged. During the process of the bearing turntable 2 driving the annular frame 3 and the contact rod 8 to rotate, the contact rod 8 will contact the contact rod 10.

[0024] During operation, when the bearing turntable 2 drives one group of the placement frame plates 301 to rotate, it will simultaneously drive the contact rod 8 to rotate. When the contact rod 8 contacts the contact rod 10 during rotation, the external circuit is connected at this time. The external controller will first control the bearing turntable 2 to stop rotating. If the lead body 5 and the capacitor body 4 are in contact with each other at this time, the external controller will continue to control the welding head 6 to weld the welding wire 7 to the contact part of the lead body 5 and the capacitor body 4. It should be noted that the contact rod 10 is connected to the external controller through a power line. The external controller is used to control the rotation of the bearing turntable 2. When the contact rod 8 and the contact rod 10 are in contact, the external circuit will be connected through the power line, so that the external controller will control the rotation of the bearing turntable 2.

[0025] Refer to Figures 2 to 6 As shown in the figure, a reciprocating cylinder 11 is arranged above the lead welding table 1. The telescopic end of the reciprocating cylinder 11 is connected to the side wall of the rectangular plate 9. Two fitting tubes 12 are installed on the side wall of the rectangular plate 9 away from the reciprocating cylinder 11. The two fitting tubes 12 and the placement frame plate 101 are designed on the same horizontal plane. The inner diameter of the fitting tube 12 is larger than the diameter of the lead body 5. During operation, when the contact rod 8 and the contact rod 10 are in contact, if the lead body 5 and the capacitor body 4 are not in contact at this time and the bearing turntable 2 is in a stopped state at this time, then the external controller will control the telescopic end of the reciprocating cylinder 11 to move, so that its telescopic end drives the rectangular plate 9 to move. The rectangular plate 9 will drive the fitting tube 12 to move. Then the fitting tube 12 will move to the outside of the lead body 5, and the lead body 5 will penetrate into the inside of the fitting tube 12. Subsequently, the fitting tube 12 will drive the lead body 5 to move towards the side close to the capacitor body 4, that is, the lead body 5 will contact the capacitor body 4, which is convenient for welding the two and realizes the function of automatic docking.

[0026] The shape of the fitting tube 12 is that one end has a large diameter and the other end has a small diameter. The inner diameter of the fitting tube 12 at the small-diameter end is smaller than the diameter of the lead body 5. During operation, when the lead body 5 extends into the inside of the fitting tube 12, due to the design of the shape of the fitting tube 12 itself, the lead body 5 will be embedded in the small-diameter end of the fitting tube 12. In this way, the fitting tube 12 will drive the lead body 5 to move towards the side close to the capacitor body 4, which is convenient for the subsequent combination of the two, solving the problem that in the prior art, it is necessary for the staff to manually dock and then weld, and the operation is relatively convenient.

[0027] Refer to Figures 3 to 7As shown in the figure, a rotating disk 13 is rotatably arranged above the bearing frustum 2. The side wall of the rotating disk 13 is connected to the output end of the motor, and the motor is installed inside the bearing frustum 2. The side wall of the rotating disk 13 is connected to the side wall of the annular frame 3 through a recycling unit. The recycling unit is used to recycle the welded capacitors. Above the lead welding table 1, a blocking frame 14 is installed. A rotating round wheel 141 is rotatably arranged on the side wall of the blocking frame 14. The side wall of the rotating round wheel 141 is connected to the side wall of the reciprocating cylinder 11 through a horizontal shaft; during operation, when the welding head 6 normally welds the contact part of the lead body 5 and the capacitor body 4, at this time, the motor drives the rotating disk 13 to rotate. The rotating disk 13 will drive the annular frame 3, the placing frame plate 301, and the capacitor body 4 to rotate through the recycling unit. At the same time, the rotating round wheel 141 will drive the reciprocating cylinder 11, the rectangular plate 9, the fitting tube 12, and the lead body 5 to rotate. Since the rotating round wheel 141 and the rotating disk 13 rotate synchronously, the entire capacitor body 4 and the lead body 5 will rotate synchronously. Therefore, the welding head 6 can slowly weld the entire contact part of the lead body 5 and the capacitor body 4. With such a design, the capacitor can be automatically rotated, improving the welding accuracy and solving the problem that in the prior art, some welding methods require workers to manually adjust the position of the capacitor.

[0028] A plurality of limiting ring frames 15 are installed on the side wall of the bearing frustum 2. The annular frame 3 is rotatably arranged inside the limiting ring frames 15. A groove adapted to the annular frame 3 is provided inside the limiting ring frames 15; during operation, the installation of the limiting ring frames 15 can facilitate the rotation of the annular frame 3, thereby facilitating the rotation of the capacitor body 4.

[0029] Refer to Figures 2 to 8 As shown in the figure, the recycling unit includes a reciprocating cylinder 16. The end of the reciprocating cylinder 16 is connected to the side wall of the rotating disk 13. A connecting frame 17 is installed at the telescopic end of the reciprocating cylinder 16. Above the annular frame 3, a frame-shaped frame 18 is installed. The end of the connecting frame 17 away from the reciprocating cylinder 16 is connected to the placing frame plate 301. Above the bearing frustum 2, a limiting column frame 201 is installed. The end of the limiting column frame 201 contacts the side wall of the capacitor body 4; during operation, after the capacitor and the lead are welded once, first control the fitting tube 12 to move away from the lead body 5, and then continue to control the bearing frustum 2 to rotate. When the contact rod 8 and the contact lever 10 of the next group are in contact, at this time, the previously welded capacitor and lead of the previous group also just move to the recycling station; at this time, the capacitors of the next group are normally welded, and the capacitors moved to the recycling station are operated as follows: By controlling the telescopic end of the reciprocating cylinder II 16 to drive the connecting frame 17 to move, the connecting frame 17 will drive the placing frame plate I 301 to move. Referring to the attached drawings, since the end of the limit post frame 201 contacts the side wall of the capacitor body 4, when the placing frame plate I 301 moves, the capacitor body 4 will be immovable under the limit, that is, the placing frame plate I 301 will move away from the bottom of the capacitor body 4. When the placing frame plate I 301 completely leaves the bottom of the capacitor body 4, the welded capacitor will fall into the recovery seat below under its own gravity. With such a design, the lead welding device of the present invention can not only continuously weld the capacitors, but also automatically recover the welded capacitors, improving the welding efficiency of the capacitors.

[0030] Referring Figures 3 to 10 As shown, a limit post plate 19 is installed below the placing frame plate I 301. The limit post plate 19 is slidably arranged in the frame-shaped frame 18. A groove adapted to the limit post plate 19 is formed in the frame-shaped frame 18. The end of the connecting frame 17 is connected to the side wall of the limit post plate 19. During operation, when the connecting frame 17 moves, the connecting frame 17 will simultaneously pull the limit post plate 19 and the placing frame plate I 301 away from the capacitor, which is convenient for the recovery of the capacitor. Moreover, under the mutual limitation of the limit post plate 19 and the frame-shaped frame 18, it is convenient for the annular frame 3 to drive the placing frame plate I 301 and the capacitor body 4 to rotate.

[0031] Two folding plates 20 are rotatably installed on the end face of the placing frame plate I 301. The two folding plates 20 are used to fix the capacitor body 4. An electric column 21 is installed on the side wall of the placing frame plate I 301. The telescopic end of the electric column 21 is hinged to the side wall of the folding plate 20. The folding plate 20 is made of rubber, and friction lines are arranged on the inner wall of the folding plate 20. During operation, when the capacitor body 4 is placed inside the placing frame plate 301, by controlling the telescopic end of the electric column 21 to drive the folding plate 20 to rotate, the two folding plates 20 on both sides are pressed against the outer wall of the capacitor body 4, that is, a certain clamping effect is exerted on the capacitor body 4, which is convenient for the subsequent annular frame 3 to drive the placing frame plate I 301 and the capacitor body 4 to rotate, so that the capacitor body 4 will not fall off.

[0032] Moreover, after welding is completed and the capacitor needs to be recovered, at this time, the electric column 21 drives the folding plate 20 to move away from the capacitor body 4, and then the recovery of the capacitor can be realized through the above operations.

[0033] Working principle: Referring to the attached Figure 1 and Figure 3As shown, a capacitor body 4 is placed inside each placing frame plate 1-301. The rotation of the bearing frustum 2 is controlled by an external controller, so that the bearing frustum 2 drives one group of placing frame plates 1-301 to move towards the side close to the placing frame plate 2-101. When one group of placing frame plates 1-301 and the placing frame plate 2-101 move to the same horizontal plane, the rotation of the bearing frustum 2 is stopped. At this time, the capacitor body 4 and the lead body 5 are also in contact with each other. Then, the lead body 5 can be welded to the surface of the capacitor body 4 through the welding head 6. After one group of capacitor bodies 4 is welded, the next group of capacitor bodies 4 can be welded by the continuous rotation of the bearing frustum 2. With such a design, the lead and the capacitor can be welded continuously. Moreover, since the placing frame plate 1-301 and the placing frame plate 2-101 are designed to be in the same horizontal plane, the docking effect between the lead and the capacitor is good, solving the problem in the prior art that it is difficult to dock the lead with the capacitor due to the small size of the lead; When the bearing frustum 2 drives one group of placing frame plates 1-301 to rotate, it will also drive the contact rod 8 to rotate at the same time. When the contact rod 8 contacts the contact lever 10 during rotation, the external circuit is connected at this time, and the external controller will first control the bearing frustum 2 to stop rotating. If the lead body 5 and the capacitor body 4 are in contact with each other at this time, the external controller will continue to control the welding head 6 to weld the welding wire 7 to the contact part of the lead body 5 and the capacitor body 4; when the contact rod 8 and the contact lever 10 are in contact, if the lead body 5 and the capacitor body 4 are not in contact at this time and the bearing frustum 2 is in a stopped state at this time, then the external controller will control the telescopic end of the reciprocating cylinder 1-11 to move, so that its telescopic end drives the rectangular plate 9 to move. The rectangular plate 9 will drive the fitting tube 12 to move. Then, the fitting tube 12 will move to the outside of the lead body 5, and the lead body 5 will penetrate into the fitting tube 12. Subsequently, the fitting tube 12 will drive the lead body 5 to move towards the side close to the capacitor body 4, that is, the lead body 5 will be in contact with the capacitor body 4, which is convenient for welding the two and plays a function of automatic docking; When the welding head 6 welds the contact part of the lead body 5 and the capacitor body 4 normally, at this time, the rotating disk 13 is driven by the motor to rotate. The rotating disk 13 drives the annular frame 3, the placing frame plate 301, and the capacitor body 4 to rotate through the recycling unit. At the same time, the rotating round wheel 141 drives the reciprocating cylinder 11, the rectangular plate 9, the fitting tube 12, and the lead body 5 to rotate. Since the rotating round wheel 141 and the rotating disk 13 rotate synchronously, the entire capacitor body 4 and the lead body 5 will rotate synchronously. Therefore, the welding head 6 can slowly weld the entire contact part of the lead body 5 and the capacitor body 4. With such a design, the capacitor can be rotated automatically, improving the welding accuracy and solving the problem in the prior art that some welding methods require workers to manually adjust the position of the capacitor. After the capacitor and the lead are welded once, first control the fitting tube 12 to move away from the lead body 5, and then continue to control the bearing round platform 2 to rotate. When the contact rod 8 of the next group contacts the contact rod 10, at this time, the capacitor and the lead that have been welded in the previous group also just move to the recycling station. At this time, the capacitors of the next group are welded normally, and the operation steps for the capacitors that have moved to the recycling station are as follows: By controlling the telescopic end of the reciprocating cylinder 16 to drive the connecting frame 17 to move, the connecting frame 17 will drive the placing frame plate 301 to move. Referring to the attached drawings, since the end of the limit column frame 201 contacts the side wall of the capacitor body 4, under the movement of the placing frame plate 301, the capacitor body 4 will remain stationary under the limit, that is, the placing frame plate 301 will move away from the bottom of the capacitor body 4. When the placing frame plate 301 completely leaves the bottom of the capacitor body 4, the welded capacitor will fall into the recycling seat below under its own gravity. With such a design, the lead welding device of the present invention can not only continuously weld the capacitors, but also automatically recycle the welded capacitors, improving the welding efficiency of the capacitors.

[0034] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
