Description

Technical Field

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

[0002] The lead welding of the capacitor is to weld and fix the lead to the gold-sprayed surface of the capacitor core, which is a very important process in the capacitor manufacturing process.

[0003] The prior art also proposes a solution for capacitor lead welding. For example, a Chinese patent with 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; wherein, slide rails are provided in the vertical direction on both sides of the support frame, and the operating table moves along the slide rails; the lifting mechanism includes a connecting wire rope, a fixed pulley set, and a drive unit; the drive unit is used to control the tensioning and loosening of the connecting wire rope. This technical solution can adjust the height of the operating table according to the different heights of capacitors, thereby facilitating welding operations.

[0004] 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, the lead needs to be aligned with the capacitor and then welded to the surface of the capacitor. However, since the lead is small and light, it is more troublesome to align it with the capacitor, which affects the welding of the two.

[0005] Therefore, a capacitor lead welding device is proposed to solve the above problems. Summary of the Invention

[0006] To solve the above technical problems, the present invention provides a capacitor lead welding device, including a lead welding table, a supporting circular table rotatably arranged above the lead welding table, a plurality of groups of annular frames arranged above the supporting circular table, the plurality of groups of annular frames being arranged in a circular array above the supporting circular table, a placement frame plate 1 being arranged above each group of annular frames, a capacitor body to be welded being placed inside the placement frame plate 1, a placement frame plate 2 being installed above the lead welding table via a bracket, a lead body being placed inside the placement frame plate 2, the placement frame plate 1 and the placement frame plate 2 being designed to be on the same horizontal plane, and a welding head and welding wire being installed above the lead welding table via a bracket.

[0007] In one embodiment of the present invention, a contact rod is installed on the side wall of each group of the placement frame plates, a rectangular plate is provided above the lead welding table through a bracket, and a contact rod is provided below the rectangular plate. When the supporting table drives the annular frame and the contact rod to rotate, the contact rod will contact the contact rod; during operation, when the supporting table drives one group of the placement frame plates to rotate, it will also drive the contact rod to rotate. When the contact rod contacts the contact rod during the rotation, the external circuit is connected, and the external controller will first control the supporting 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 between the lead body and the capacitor body.

[0009] In one embodiment of the present invention, the shape of the fitting tube is a large diameter at one end and a small diameter at the other end, and 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 fitting tube, due to the shape design of the fitting tube itself, the lead body will be embedded in the end of the fitting tube with a smaller diameter, so that the fitting tube will drive the lead body to move to the side close to the capacitor body, facilitating the subsequent combination of the two, solving the process of manual docking and subsequent welding required by staff in the prior art, and the operation is more convenient.

[0010] In one embodiment of the present invention, a rotating disk is rotatably provided above the supporting circular table, the side wall of the rotating disk is connected to the output end of the motor, the motor is installed inside the supporting circular table, the side wall of the rotating disk is connected to the side wall of the annular frame through a recovery unit, and the recovery unit is used to recycle the welded capacitors. A retaining frame is installed above the lead welding table, and a rotating circular wheel is rotatably provided on the side wall of the retaining frame, and the side wall of the rotating circular wheel is connected to the side wall of the reciprocating cylinder through a horizontal axis.

[0011] In one embodiment of the present invention, a plurality of groups of limiting ring frames are installed on the side walls of the supporting truncated table, and the ring frames are rotatably arranged inside the limiting ring frames, and grooves adapted to the ring frames are provided inside the limiting ring frames; when working, the limiting ring frames are provided to facilitate the rotation of the ring frames, thereby facilitating the rotation of the capacitor body.

[0012] In one embodiment of the present invention, the recovery unit includes a reciprocating cylinder 2, the end of which is connected to the side wall of the rotating disk, the telescopic end of the reciprocating cylinder 2 is equipped with a connecting frame, a frame-shaped frame is installed above the annular frame, the end of the connecting frame away from the reciprocating cylinder 2 is connected to a placing frame plate 1, a limiting column frame is installed above the supporting table, and the end of the limiting column frame is in contact with the side wall of the capacitor body.

[0013] In one embodiment of the present invention, a limiting column plate is installed below the placement frame plate 1, and the limiting column plate is slidably set in the frame frame. A groove suitable for the limiting column plate is provided in the frame frame, and 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 1 away from the capacitor, which is convenient for the recovery of the capacitor, and the limiting column plate and the frame frame are mutually limited, which can facilitate the annular frame to drive the placement frame plate 1 and the capacitor body to rotate.

[0014] In one embodiment of the present invention, two folding plates are rotatably installed on the end surface of the placement frame plate one, and the two folding plates are used to fix the capacitor body. The side wall of the placement frame plate one is installed with an electric column, and 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, the folding plates are driven to rotate by controlling the telescopic end of the electric column, so that the folding plates on both sides are pressed against the outer wall of the capacitor body, that is, they have a certain clamping effect on the capacitor body, which makes it convenient for the subsequent annular frame to drive the placement frame plate one and the capacitor body to rotate, so that the capacitor body will not fall.

[0015] In one embodiment of the present invention, the folding plate is made of rubber, and the inner wall of the folding plate is provided with friction patterns.

[0016] The above technical solution of the present invention has the following advantages over the prior art:

[0017] The capacitor lead welding device described in the present invention controls the movement of the telescopic end of a reciprocating cylinder so that the telescopic end drives the movement of a rectangular plate, which in turn drives the movement of a fitting tube. The fitting tube then moves to the outside of the lead body, and the lead body penetrates into the fitting tube. The fitting tube then drives the lead body to move toward the side close to the capacitor body, that is, the lead body and the capacitor body come into contact with each other, thereby facilitating the welding of the two and achieving an automatic docking function.

[0018] In the capacitor lead welding device described in the present invention, since the end of the limiting column frame contacts the side wall of the capacitor body, when the placement frame plate moves, the capacitor body will remain in a fixed position under the limit, that is, the placement frame plate will be away from the bottom of the capacitor body. When the placement frame plate completely leaves the bottom of the capacitor body, the welded capacitor will fall to the recovery seat below under the action of its own gravity. With this design, the lead welding device of the present invention can not only continuously weld capacitors, but also automatically recycle welded capacitors, thereby improving the welding efficiency of the capacitors.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0032] Reference 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, a supporting circular table 2 is rotatably provided above the lead welding table 1, a plurality of groups of annular frames 3 are provided above the supporting circular table 2, and the plurality of groups of annular frames 3 are designed in a circular array above the supporting circular table 2, a placement frame plate 1 301 is provided above each group of annular frames 3, a capacitor body 4 to be welded is placed inside the placement frame plate 1 301, a placement frame plate 2 101 is installed above the lead welding table 1 via a bracket, a lead body 5 is placed inside the placement frame plate 2 101, the placement frame plate 1 301 and the placement frame plate 2 101 are designed to be on the same horizontal plane, and a welding head 6 and a welding wire 7 are installed above the lead welding table 1 via a bracket;

[0033] 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 controlled by an external hydraulic system, that is, the welding head 6 and the welding wire 7 can be controlled by the external hydraulic system to approach the contact position between the lead body 5 and the capacitor column head 4. The control method of the hydraulic system and the welding method of the welding head 6 are both existing technologies and are not redundantly described in the embodiment of the present invention.

[0034] Refer to the attached Figure 1 and Figure 3As shown, a capacitor body 4 is placed inside each placement frame plate 1 301, and the rotation of the supporting table 2 is controlled by an external controller, so that the supporting table 2 drives one group of placement frame plates 1 301 to move toward the side close to the placement frame plate 2 101. When one group of placement frame plates 1 301 and the placement frame plate 2 101 move to the same horizontal plane, the rotation of the supporting table 2 is stopped. At this time, the capacitor body 4 and the lead body 5 are also in contact with each other. Thereafter, the lead body 5 can be welded to the surface of the capacitor body 4 through the welding head 6. After the welding of one group of capacitor bodies 4 is completed, the next group of capacitor bodies 4 can be welded by continuing to rotate the supporting table 2. With this design, the leads and capacitors can be welded continuously. Moreover, since the placement frame plate 1 301 and the placement frame plate 2 101 are designed to be on the same horizontal plane, the leads and capacitors have a good docking effect, which solves the problem in the prior art that the leads are small and light, making it difficult to dock with the capacitors.

[0035] It should be noted that the lower end surface of the supporting truncated platform 2 is connected to the output end of the motor.

[0036] A contact rod 8 is installed on the side wall of each group of the placement frame plates 301, a rectangular plate 9 is arranged above the lead welding table 1 through a bracket, and a contact rod 10 is arranged below the rectangular plate 9. When the supporting circular table 2 drives the annular frame 3 and the contact rod 8 to rotate, the contact rod 8 will contact the contact rod 10.

[0037] During operation, when the supporting platform 2 drives one of the mounting frame plates 301 to rotate, it simultaneously drives the contact rod 8 to rotate. When the contact rod 8 contacts the contact rod 10 during rotation, the external circuit is connected, and the external controller first controls the supporting platform 2 to stop rotating. If the lead body 5 and the capacitor body 4 are in contact at this time, the external controller continues to control the welding head 6 to weld the welding wire 7 to the contact point between the lead body 5 and the capacitor body 4. It should be noted that the contact rod 10 is connected to the external controller via a power cord. The external controller is used to control the rotation of the supporting platform 2. When the contact rod 8 and the contact rod 10 contact, the external circuit is connected via the power cord, thereby controlling the rotation of the supporting platform 2.

[0038] Reference Figures 2 to 6As shown, a reciprocating cylinder 11 is provided above the lead welding station 1, and the telescopic end of the reciprocating cylinder 11 is connected to the side wall of the rectangular plate 9. Two sets of fitting tubes 12 are installed on the side wall of the rectangular plate 9 away from the reciprocating cylinder 11. The two sets of fitting tubes 12 and the placement frame plate 101 are designed to be on the same horizontal plane. The inner diameter of the fitting tube 12 is larger than the diameter of the lead body 5. When working, 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 load-bearing The table 2 is in a stopped state, and then the external controller will control the telescopic end of the reciprocating cylinder 11 to move, so that the telescopic end drives the rectangular plate 9 to move, and the rectangular plate 9 drives the fitting tube 12 to move, and 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, and then the fitting tube 12 will drive the lead body 5 to move to the side close to the capacitor body 4, that is, the lead body 5 will contact with the capacitor body 4, which facilitates the welding of the two and plays the function of automatic docking.

[0039] The shape of the fitting tube 12 is that one end has a large diameter and the other end has a small diameter, and the inner diameter of the fitting tube 12 at the end with a small diameter is smaller than the diameter of the lead body 5; during operation, when the lead body 5 is extended into the fitting tube 12, due to the shape design of the fitting tube 12 itself, the lead body 5 will be embedded in the end with a smaller diameter of the fitting tube 12, so that the fitting tube 12 will drive the lead body 5 to move to the side close to the capacitor body 4, which is convenient for the subsequent combination of the two, and solves the process of manual docking and welding required by the staff in the existing technology, and the operation is more convenient.

[0040] Reference Figures 3 to 7As shown, a rotating disk 13 is rotatably provided above the supporting circular platform 2, and the side wall of the rotating disk 13 is connected to the output end of the motor. The motor is installed inside the supporting circular platform 2, and the side wall of the rotating disk 13 is connected to the side wall of the annular frame 3 through a recovery unit. The recovery unit is used to recycle the capacitors that have been welded. A retaining frame 14 is installed above the lead welding station 1, and a rotating circular wheel 141 is rotatably provided on the side wall of the retaining frame 14. The side wall of the rotating circular wheel 141 is connected to the side wall of the reciprocating cylinder 11 through a horizontal axis. During operation, when the welding head 6 welds the contact parts of the lead body 5 and the capacitor body 4 normally, the rotating disk is driven by the motor. 13 rotates, and the rotating disk 13 drives the annular frame 3, the placement frame plate 301, and the capacitor body 4 to rotate through the recovery unit, and at the same time, the rotating circular 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 circular 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 area between the lead body 5 and the capacitor body 4. With this design, the capacitor can be automatically rotated, the welding accuracy is improved, and the problem that some welding methods in the prior art require the staff to manually adjust the capacitor position is solved.

[0041] The side walls of the supporting platform 2 are equipped with multiple sets of limiting ring frames 15, and the annular frame 3 is rotatably arranged inside the limiting ring frame 15. The limiting ring frame 15 is provided with a groove adapted to the annular frame 3; when working, the limiting ring frame 15 is provided to facilitate the rotation of the annular frame 3, thereby facilitating the rotation of the capacitor body 4.

[0042] Reference Figures 2 to 8 As shown, the recovery unit includes a reciprocating cylinder 16, the end of the reciprocating cylinder 16 is connected to the side wall of the rotating disk 13, and a connecting frame 17 is installed at the telescopic end of the reciprocating cylinder 16. A frame frame 18 is installed above the annular frame 3, and the end of the connecting frame 17 away from the reciprocating cylinder 16 is connected to the placement frame plate 301. A limiting column frame 201 is installed above the supporting circular table 2, and 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, the bonding tube 12 is first controlled to move away from the lead body 5, and then the supporting circular table 2 is continued to be controlled to rotate. When the contact rod 8 of the next group contacts the contact rod 10, the capacitor and lead of the previous group that have been welded are also moved to the recovery station; at this time, the capacitors of the next group are welded normally, and the operation steps of the capacitors moved to the recovery station are as follows:

[0043] By controlling the telescopic end of the reciprocating cylinder 2 16 to drive the connecting frame 17 to move, the connecting frame 17 will drive the placement frame plate 301 to move. As shown in the accompanying drawings, since the end of the limiting column frame 201 is in contact with the side wall of the capacitor body 4, the capacitor body 4 will not move under the limit when the placement frame plate 301 moves, that is, the placement frame plate 301 will be away from the bottom of the capacitor body 4. When the placement frame plate 301 completely leaves the bottom of the capacitor body 4, the welded capacitor will fall to the recovery seat below under the action of its own gravity. With this design, the lead welding device of the present invention can not only continuously weld the capacitor, but also automatically recycle the welded capacitor, thereby improving the welding efficiency of the capacitor.

[0044] Reference Figures 3 to 10 As shown, a limiting column plate 19 is installed under the placement frame plate 301, and the limiting column plate 19 is slidably set in the frame frame 18. A groove suitable for the limiting column plate 19 is provided in the frame frame 18, and the end of the connecting frame 17 is connected to the side wall of the limiting column plate 19; during operation, when the connecting frame 17 moves, the connecting frame 17 will simultaneously pull the limiting column plate 19 and the placement frame plate 301 away from the capacitor, which is convenient for the recovery of the capacitor, and the limiting column plate 19 and the frame frame 18 limit each other, which can facilitate the annular frame 3 to drive the placement frame plate 301 and the capacitor body 4 to rotate.

[0045] Two folding plates 20 are rotatably installed on the end surface of the placement frame plate 301, and the two folding plates 20 are used to fix the capacitor body 4. The side wall of the placement frame plate 301 is installed with an electric column 21, and the telescopic end of the electric column 21 is hinged to the side wall of the folding plate 20. The material of the folding plate 20 is rubber, and the inner wall of the folding plate 20 is provided with friction grooves; during operation, when the capacitor body 4 is placed inside the placement frame plate 301, the telescopic end of the electric column 21 is controlled to drive the folding plate 20 to rotate, so that the folding plates 20 on both sides are pressed on the outer wall of the capacitor body 4, that is, the capacitor body 4 has a certain clamping effect, which makes it convenient for the subsequent annular frame 3 to drive the placement frame plate 301 and the capacitor body 4 to rotate, so that the capacitor body 4 will not fall.

[0046] Moreover, after welding is completed, when the capacitor needs to be recovered, the folding plate 20 is driven away from the capacitor body 4 by the electric column 21, and then the capacitor can be recovered through the above operation.

[0047] Working principle: Refer to the attached Figure 1 and Figure 3As shown, a capacitor body 4 is placed inside each placement frame plate 1 301 , and the rotation of the supporting table 2 is controlled by an external controller, so that the supporting table 2 drives one group of placement frame plates 1 301 to move toward the side close to the placement frame plate 2 101 . When one group of placement frame plates 1 301 and the placement frame plate 2 101 move to the same horizontal plane, the rotation of the supporting table 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 the welding of one group of capacitor bodies 4 is completed, the next group of capacitor bodies 4 can be welded by continuing to rotate the supporting table 2. With this design, the leads and capacitors can be welded continuously. Moreover, since the placement frame plate 1 301 and the placement frame plate 2 101 are designed to be on the same horizontal plane, the lead and capacitor have a good docking effect, which solves the problem in the prior art that the leads are small and difficult to dock with the capacitors.

[0048] When the supporting table 2 drives one of the placing frame plates 301 to rotate, it will also drive the contact rod 8 to rotate. When the contact rod 8 contacts the contact rod 10 during the rotation, the external circuit is connected. The external controller will first control the supporting table 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 between the lead body 5 and the capacitor body 4. 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, the external controller will continue to control the welding head 6 to weld the welding wire 7 to the contact part between the lead body 5 and the capacitor body 4. When the lead body 5 is touched, and the supporting table 2 is in a stopped state, the external controller will then control the telescopic end of the reciprocating cylinder 11 to move, so that the telescopic end drives the rectangular plate 9 to move, and the rectangular plate 9 drives the fitting tube 12 to move, and then the fitting tube 12 moves to the outside of the lead body 5, and the lead body 5 passes into the fitting tube 12, and then the fitting tube 12 drives the lead body 5 to move to the side close to the capacitor body 4, that is, the lead body 5 and the capacitor body 4 come into contact with each other, which facilitates the welding of the two and plays the role of automatic docking;

[0049] When the welding head 6 is welding the contact part of the lead body 5 and the capacitor body 4 normally, the rotating disk 13 is driven by the motor to rotate, and the rotating disk 13 drives the annular frame 3, the placement frame plate 301, and the capacitor body 4 to rotate through the recovery unit, and 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, so the welding head 6 can weld the entire contact part of the lead body 5 and the capacitor body 4. The capacitor is slowly welded at the same time. This design can automatically rotate the capacitor, improve the welding accuracy, and solve the problem that some welding methods in the prior art require workers to manually adjust the position of the capacitor. After the capacitor and the lead are welded once, the bonding tube 12 is first controlled to move away from the lead body 5, and then the supporting table 2 is continuously controlled to rotate. When the contact rod 8 and the contact rod 10 of the next group are in contact, the capacitor and lead of the previous group that have been welded are also moved to the recovery station. At this time, the capacitor of the next group is welded normally, and the operation steps of the capacitor moved to the recovery station are as follows:

[0050] By controlling the telescopic end of the reciprocating cylinder 2 16 to drive the connecting frame 17 to move, the connecting frame 17 will drive the placement frame plate 301 to move. As shown in the accompanying drawings, since the end of the limiting column frame 201 is in contact with the side wall of the capacitor body 4, the capacitor body 4 will not move under the limit when the placement frame plate 301 moves, that is, the placement frame plate 301 will be away from the bottom of the capacitor body 4. When the placement frame plate 301 completely leaves the bottom of the capacitor body 4, the welded capacitor will fall to the recovery seat below under the action of its own gravity. With this design, the lead welding device of the present invention can not only continuously weld the capacitor, but also automatically recycle the welded capacitor, thereby improving the welding efficiency of the capacitor.

[0051] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
