Description

Technical Field

[0001] The invention belongs to the field of welding, in particular to an automatic welding machine for capacitor cores. Background Art

[0002] A capacitor is an electronic component that can store and release electrical energy. It is widely used in electronic circuits. Common capacitors are generally cylindrical and have the advantages of compact structure, good heat dissipation, and high mechanical strength. The core of the capacitor is generally made of metal foil and is used to store charge. The welding between the capacitor core and the lead is a key link in the capacitor manufacturing process. The lead is spot-welded to the end face of the capacitor core for subsequent electrical connection between other equipment and the capacitor.

[0003] A patent application with publication number CN110125569A discloses a battery terminal welding device, including a battery conveying device, a battery terminal conveying device, a battery terminal grasping device and a battery terminal welding mechanism. The above-mentioned battery terminal welding device can achieve welding of battery terminals to battery poles of a battery workpiece through the cooperation of the battery conveying device, the battery terminal conveying device, the battery terminal grasping device and the battery terminal welding mechanism, without the need for manual operation, with a high degree of automation and reduced labor costs.

[0004] The traditional capacitor core welding method requires first determining the welding position of the capacitor core, and then connecting the leads to be welded with the welding position of the capacitor core before proceeding with the subsequent welding work. However, the leads are relatively small, and the welding end of the capacitor core is difficult to confirm. The traditional mechanical grasping method cannot guarantee the accurate grasping effect, which easily leads to the problem of excessively high defective rate.

[0005] To this end, the present invention provides a capacitor core automatic welding machine. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: an automatic capacitor core welding machine according to the present invention comprises a base plate, the top of the base plate is fixedly connected to two parallel supporting platforms, the top surface of the supporting platform is provided with a plurality of fixed sleeves that are continuously movable, a welding gun is provided above the middle part of the supporting platform, the welding gun is arranged in an inclined manner, the bottom of the welding gun is fixedly connected to a movable platform for driving the welding gun to move, a winding box is provided above the welding gun, the output end of the winding box is fixedly connected to an extrusion head, the end of the extrusion head is provided with a fixed disk that can rotate and translate, a screening platform is provided above the end of the support platform, the screening platform comprises a driving box that can be lifted and translated, a servo motor is provided inside the driving box, the output end of the servo motor is fixedly connected to a rotating wheel, an entry hole for transporting the capacitor core is opened inside the rotating wheel, and cameras are installed on both ends of the outer side of the entry hole;

[0008] The capacitor core is continuously transported to one side of the rotating wheel using a transport device, and the direction of the end of the capacitor core is observed through a camera. There are many types of capacitor cores, most of which require the core to be assembled and then tested with power. After the test is completed, the aluminum foil protrusion of the core is flat-core welded. The welded part is generally the lead. The end of the core is observed through a camera to see if it is the end of the aluminum foil protrusion required. The capacitor core suitable for this device is the most common cylindrical shape, and the welding position is at the end of the cylinder. If it is observed that the aluminum foil protrusion is at one end, the transport device inserts the capacitor core into the entry hole. After the capacitor core is inserted into the hole, the entry hole will translate the capacitor core to the other end of the entry hole, and the servo motor will drive the rotating wheel to rotate counterclockwise at the same time. At this time, the protruding end of the aluminum foil of the capacitor core will face upwards, and then the entry hole will discharge the capacitor core downwards, and the bottom of the capacitor core will be fixed to the fixed sleeve; if it is observed that it is not the protruding end of the aluminum foil, then after the capacitor core is inserted into the entry hole, the rotating wheel will be directly rotated clockwise, so that the protruding end of the aluminum foil of the capacitor core will still face upwards, and then the capacitor core will be fixed in the fixed sleeve, so that the fixed sleeve can move with the capacitor core; the rotation direction of the rotating wheel is Figure Fivefor reference; when it moves to the bottom of the welding gun, an electric winding roller is installed in the winding box for winding a large amount of metal leads. Through the rotation of the electric winding roller, the lead will be discharged from the extruder head. When the lead is just discharged, the end of the lead is fixed by the fixed disk, and the fixed disk is controlled to move outward to stretch the lead to the required length. Then the end of the extruder head squeezes the lead to cut the lead; the fixed disk is controlled to rotate, and the lead and the fixed disk are rotated to a vertical state. At the same time, the fixed disk is controlled to move to the top of the fixed sleeve and the capacitor core, and the bottom of the lead is fit with the protruding position of the aluminum foil of the capacitor core, and the welding gun is used to weld the fitting part; thereby completing the lead welding of the capacitor core. Through this setting, not only the fully automatic selection of the capacitor core is realized, and the capacitor core is moved to the designated welding location in the required direction, but also the lead of the required length can be accurately pulled out, and the end of the lead is controlled to be combined with the welding part of the capacitor core, ensuring the fully automated process of the welding process, thereby improving the welding efficiency.

A plurality of conveyor belts arranged parallel to the entry hole are installed in the entry hole, and two electric universal wheels are installed in the middle of the cross-shaped entry hole. The cross-shaped entry hole creates two intersecting through-channels. When one of the through-channels receives the capacitor core, the conveyor belt is controlled according to the information observed by the camera 1, so that the capacitor core can be fixed in place or transferred to the other end of the through-channel. After that, no matter whether the rotating wheel is rotated clockwise or counterclockwise, it rotates 90 degrees, so that the other through-channel can be transferred. A through channel rotates to a horizontal state and receives the next capacitor core, while the previous capacitor core is at the bottom of the rotating wheel and is discharged outward through the conveyor belt. Through this setting, the rotating wheel can synchronously grasp and discharge the capacitor core, doubling its own transfer efficiency, thereby realizing the function of quickly determining the direction of the capacitor core and fixing it to the fixed sleeve in the correct direction; the electric universal wheel is used to assist the movement of the capacitor core when the capacitor core passes through the center of the entry hole. The electric universal wheel drives and rotates to adapt to the two directions of the cross-shaped entry hole.

The rotation of the fixed disk is controlled by the rotating table, and a motor is installed in the rotating table to control the fixed disk to rotate to a horizontal or vertical state. The entire winding box is driven to rise and fall by the electric telescopic rod three, so that no matter how long the lead wire is, its bottom can contact the top surface of the capacitor core.

At the same time, the fourth electric telescopic rod can control the horizontal position of the fixed plate and the lead, and the second electric telescopic rod is used to push outward to fine-tune the connection position of the bottom of the lead and the capacitor core, thereby ensuring the accuracy of the welding position.

[0013] Preferably, multiple fixing sleeves are connected end to end, a fixing hole is provided on the top of the fixing sleeve, and a friction roll of elastic material is fixed in the fixing hole. The fixing sleeves connected end to end only need to continuously recycle the fixing sleeve at one end and continuously supply the fixing sleeve at the other end to control the synchronous movement of multiple fixing sleeves. The fixing hole is used to insert and fix the capacitor core, and the friction roll can increase the friction force on the capacitor core, thereby ensuring the firmness of the fixation and preventing movement and falling off.

[0014] Preferably, a discharge box and a disassembly box are respectively installed at both ends of the base plate, and friction wheels are provided in the discharge box and the disassembly box. The friction wheels are located above the support platform, and a transmission hole is opened in the middle of the disassembly box.

[0032] like Figures 1 to 8 As shown, an automatic welding machine for a capacitor core according to an embodiment of the present invention includes a base plate 6, the top of which is fixedly connected to two parallel support platforms 14, the top surface of which is provided with a plurality of continuously moving fixed sleeves 16, a welding gun 30 is provided above the middle portion of the support platform 14, the welding gun 30 is arranged in an inclined manner, the bottom of the welding gun 30 is fixedly connected to a movable platform 22 for driving the welding gun 30 to move, a winding box 4 is provided above the welding gun 30, the output end of the winding box 4 is fixedly connected to an extrusion head 24, the end of the extrusion head 24 is provided with a fixed disk 26 capable of rotating and translating, a screening table 2 is provided above the end of the support platform 14, the screening table 2 includes a driving box 11 capable of lifting and translating, a servo motor is provided inside the driving box 11, the output end of the servo motor is fixedly connected to a rotating wheel 10, an entry hole 13 for transporting a capacitor core is opened inside the rotating wheel 10, and cameras 19 are installed on both ends of the outer side of the entry hole 13;

[0033] The capacitor core is continuously transported to one side of the rotating wheel 10 by using a transport device, and the direction of the end of the capacitor core is observed through a camera 19; there are many types of capacitor cores, most of which require the core to be assembled and then tested for power on. After the test is completed, the aluminum foil protrusion of the core is flat-core welded, and the welded part is generally the lead; the core end is observed through a camera 19 to see if it is the desired aluminum foil protrusion end. The capacitor core applicable to this device is the most common cylindrical shape, and the welding position is at the end of the cylinder; if it is observed that it is the aluminum foil protrusion end, then after the transport device inserts the capacitor core into the entry hole 13, the entry hole 13 will translate the capacitor core to the other end of the entry hole 13, and at the same time, the servo motor drives the rotating wheel 10 to rotate counterclockwise. At this time, the protruding end of the aluminum foil of the capacitor core faces upward, and then the entry hole 13 discharges the capacitor core downward, and the bottom of the capacitor core will be fixed to the fixing sleeve 16; if it is observed that it is not the protruding end of the aluminum foil, then after the capacitor core is inserted into the entry hole 13, the rotating wheel 10 is directly rotated clockwise, so that the protruding end of the aluminum foil of the capacitor core can still face upward, and then the capacitor core is fixed in the fixing sleeve 16, so that the fixing sleeve 16 can move with the capacitor core; the rotation direction of the rotating wheel 10 is Figure 5 For reference; when the fixed sleeve 16 and the capacitor core are moved to the bottom of the welding gun 30, an electric winding roller is installed in the winding box 4 for winding a large amount of metal leads. Through the rotation of the electric winding roller, the lead is discharged outward from the extrusion head 24. When the lead is just discharged, the end of the lead is fixed by the fixed disk 26, and the fixed disk 26 is controlled to move outward to stretch the lead to the required length. After that, the end of the extrusion head 24 squeezes the lead to cut the lead; the fixed disk 26 is controlled to rotate, and the lead and the fixed disk 26 are rotated to a vertical state. At the same time, the fixed disk 26 is controlled to move above the fixed sleeve 16 and the capacitor core, and the bottom of the lead is aligned with the capacitor. The protruding portion of the aluminum foil of the core is fitted, and the fitting portion is welded using a welding gun 30. The welding gun 30 generates heat by releasing an arc, and the heat acts on the lead wire, causing the end of the lead wire to melt and fit with the protruding portion of the aluminum foil of the capacitor core, so that the two are fixedly welded; thereby completing the lead welding work of the capacitor core. Through this setting, not only is the capacitor core fully automatically selected, and the capacitor core is moved to the designated welding location in the required orientation, but the lead wire of the required length can also be accurately extracted, and the end of the lead wire is controlled to be combined with the welding portion of the capacitor core, ensuring a fully automated process of the welding process, thereby improving welding efficiency.

A plurality of conveyor belts 18 arranged parallel to the entry hole 13 are installed in the entry hole 13, and two electric universal wheels 17 are installed in the middle of the cross-shaped entry hole 13;

[0035] During operation, the cross-shaped entry hole 13 creates two intersecting through-channels. After one of the through-channels receives the capacitor core, the conveyor belt 18 is controlled according to the information observed by the camera 19, so that the capacitor core can be fixed in place or transferred to the other end of the through-channel. After that, whether the rotating wheel 10 is rotated clockwise or counterclockwise, it rotates ninety degrees, so that the other through-channel can be rotated to a horizontal state and the next capacitor core can be received. The previous capacitor core is at the bottom of the rotating wheel 10 and is discharged outward through the conveyor belt 18. Through this setting, the rotating wheel 10 can synchronously grasp and discharge the capacitor core, doubling its own transfer efficiency, thereby realizing the function of quickly determining the direction of the capacitor core and fixing it to the fixed sleeve 16 in the correct direction; the electric universal wheel 17 is used to assist the movement of the capacitor core when the capacitor core passes through the center position of the entry hole 13. The electric universal wheel 17 drives and rotates to adapt to the two directions of the cross-shaped entry hole 13.

[0036] Two vertically arranged electric telescopic rods 3 23 are fixedly connected to the outside of the winding box 4. An electric telescopic rod 4 25 is fixedly connected to the end of the winding box 4. The electric telescopic rod 4 25 is located above the extrusion head 24. The end of the electric telescopic rod 4 25 is fixedly connected to a rotating platform 27. The rotating end of the rotating platform 27 is fixedly connected to a fixed plate 26.

[0037] During operation, the distance between the fixed disk 26 and the extrusion head 24 is controlled by extending the electric telescopic rod 25, thereby determining the length of the pulled lead wire. The rotation of the fixed disk 26 is controlled by the rotating table 27. The rotating table 27 is equipped with a motor to control the fixed disk 26 to rotate to a horizontal or vertical state. The electric telescopic rod 3 23 drives the entire winding box 4 to rise and fall, so that no matter how long the lead wire is, its bottom can contact the top surface of the capacitor core.

[0038] An electric slide rail is fixedly connected to the interior of the base plate 6, a movable end of the electric slide rail is fixedly connected to a movable platform 22, a top of the movable platform 22 is fixedly connected to an electric telescopic rod 5, and a top of the electric telescopic rod 5 is fixedly connected to a welding gun 30;

[0043] During operation, the fixed sleeves 16 connected end to end only need to continuously recycle at one end and continuously supply at the other end to control the synchronous movement of multiple fixed sleeves 16. The fixing hole 29 is used to insert and fix the capacitor core, and the friction roll 28 can increase the friction force on the capacitor core. The friction roll 28 uses a material that does not generate static electricity to ensure the firmness of the fixation and prevent movement and falling off.

[0048] A vibrating plate 1 is provided on one side of the screening table 2. A guide tube 7 is fixedly connected to the output end of the vibrating plate 1. The end of the guide tube 7 faces the middle of the rotating wheel 10.

[0049] During operation, multiple capacitor cores are placed in the vibration disk 1, and the capacitor cores are continuously transferred upward by the action of the vibration disk 1. According to the shape of the capacitor core, a suitable vibration disk 1 and an adapted guide tube 7 are selected to send the capacitor cores one by one to one side of the rotating wheel 10.

[0050] A cutting plate capable of lifting and lowering is provided in the transmission hole, and the transmission hole passes through the front and rear ends of the disassembly box 5;

[0051] During operation, the last fixing sleeve 16 can be cut off by the lifting cutting plate when the fixing sleeve 16 passes by, so that the fixing sleeve 16 and the welded capacitor core can be stored separately. The fixing sleeves 16 connected end to end have cut marks on the surface and will break under the action of extrusion. They can also be discharged directly while keeping the end together, depending on the subsequent processing method.

[0052] During operation, the transport equipment is used to continuously transport the capacitor core to one side of the rotating wheel 10, and the direction of the end of the capacitor core is observed through a camera 19; there are many types of capacitor cores, most of which require the core to be assembled and then tested for power on. After the test is completed, the aluminum foil protrusion of the core is flat-core welded, and the welded part is generally the lead; the core end is observed through a camera 19 to see if it is the required aluminum foil protrusion end. The capacitor core applicable to this device is the most common cylindrical shape, and the welding position is at the end position of the cylinder; if it is observed that it is the aluminum foil protrusion end, then after the transport equipment inserts the capacitor core into the entry hole 13, it is entered The entry hole 13 will translate the capacitor core to the other end of the entry hole 13, and at the same time, the servo motor drives the rotating wheel 10 to rotate counterclockwise. At this time, the protruding end of the aluminum foil of the capacitor core faces upward, and then the entry hole 13 discharges the capacitor core downward, and the bottom of the capacitor core will be fixed to the fixing sleeve 16; if it is observed that it is not the protruding end of the aluminum foil, then after the capacitor core is inserted into the entry hole 13, the rotating wheel 10 is directly rotated clockwise, so that the protruding end of the aluminum foil of the capacitor core can still face upward, and then the capacitor core is fixed in the fixing sleeve 16, so that the fixing sleeve 16 can move with the capacitor core; the rotation direction of the rotating wheel 10 is Figure FiveFor reference; when it moves to the bottom of the welding gun 30, an electric winding roller is installed in the winding box 4 for winding a large amount of metal lead. Through the rotation of the electric winding roller, the lead is discharged outward from the extrusion head 24. When the lead is just discharged, the end of the lead is fixed by the fixed disk 26, and the fixed disk 26 is controlled to move outward to stretch the lead to the required length. After that, the end of the extrusion head 24 squeezes the lead to cut the lead; the fixed disk 26 is controlled to rotate, and the lead and the fixed disk 26 are rotated to a vertical state, and the fixed disk 26 is controlled to move to the fixed sleeve 16 and the top of the capacitor core, and make the bottom of the lead fit with the protruding position of the aluminum foil of the capacitor core, and use the welding gun 30 to weld the fitting part; thereby completing the lead welding work of the capacitor core. Through this setting, not only the capacitor core is fully automatically selected, the capacitor core is moved to the designated welding position in the required orientation, but also the lead of the required length can be accurately extracted and the end of the lead is controlled to be combined with the welding position of the capacitor core, ensuring the full automation of the welding process, thereby improving the welding efficiency.

[0053] The cross-shaped entry hole 13 creates two intersecting through-channels. When one of the through-channels receives a capacitor core, the conveyor belt 18 is controlled based on the information observed by camera 19, thereby fixing the capacitor core in place or transferring the capacitor core to the other end of the through-channel. The rotating wheel 10 then rotates 90 degrees clockwise or counterclockwise, so that the other through-channel can be rotated to a horizontal state and the next capacitor core can be received. The previous capacitor core is at the bottom of the rotating wheel 10 and is discharged outward via the conveyor belt 18. This arrangement allows the rotating wheel 10 to simultaneously grasp and discharge the capacitor core, doubling its own transfer efficiency, thereby achieving the function of quickly determining the orientation of the capacitor core and fixing it to the fixing sleeve 16 in the correct orientation. The electric universal wheel 17 is used to assist the movement of the capacitor core when the capacitor core passes through the center of the entry hole 13. The electric universal wheel 17 is driven and rotated to adapt to the two directions of the cross-shaped entry hole 13.

[0054] The distance between the fixed disk 26 and the extrusion head 24 is controlled by extending the electric telescopic rod 25, thereby determining the length of the pulled lead wire. The rotation of the fixed disk 26 is controlled by the rotating table 27. The rotating table 27 is equipped with a motor to control the fixed disk 26 to rotate to a horizontal or vertical state.

This ensures that no matter how long the lead wire is, its bottom can contact the top surface of the capacitor core.

[0055] The movable platform 22 is moved horizontally by an electric slide rail, and the height of the welding gun 30 is controlled by an electric telescopic rod 5. At the same time, the movement of the fixed sleeve 16 and the lifting and lowering setting of the winding box 4 are coordinated to ensure that the end of the lead wire can be accurately connected to the welding position of the capacitor core.

[0056] The connection position between the lead wire and the capacitor core is observed through the second camera 20 of the observation platform 15, and the moving parts such as the fourth electric telescopic rod 25 are fine-tuned to ensure the accuracy of the connection position. At the same time, the fourth electric telescopic rod 25 can control the horizontal position of the fixed plate 26 and the lead wire, and the second electric telescopic rod 21 is used to push outward to fine-tune the connection position between the bottom of the lead wire and the capacitor core, thereby ensuring the accuracy of the welding position;

[0057] The end-to-end fixed sleeves 16 only need to continuously recycle the fixed sleeves 16 at one end and continuously supply the fixed sleeves 16 at the other end to control the synchronous movement of multiple fixed sleeves 16. The fixing holes 29 are used to insert and fix the capacitor core, and the friction coils 28 can increase the friction force on the capacitor core to ensure the firmness of the fixation and prevent movement and falling off.

[0058] The outer edge of the fixed sleeve 16 is clamped by the friction wheel and the support platform 14, and the friction wheel rotates to provide a moving force to the fixed sleeve 16, so that multiple fixed sleeves 16 can move on the support platform 14;

[0059] The lifting and lowering of the drive box 11 is controlled by the electric telescopic rod 8, and the horizontal position of the drive box 11 is adjusted by the screw nut mechanism 9, thereby fine-tuning the position of the rotating wheel 10 to better receive and discharge the capacitor core;

[0060] By placing multiple capacitor cores on the vibration plate 1, the capacitor cores are continuously moved upward by the vibration plate 1. According to the shape of the capacitor core, a suitable vibration plate 1 and an adapted guide tube 7 are selected, so that the capacitor cores are sent one by one to one side of the rotating wheel 10.

[0061] By lifting the cutting plate, the last fixing sleeve 16 can be cut off when the fixing sleeve 16 passes by, so that the fixing sleeve 16 and the welded capacitor core can be stored separately. The fixing sleeves 16 connected end to end have cut marks on the surface and will break under the action of extrusion. They can also be discharged directly with the end to end kept, depending on the subsequent processing method.
