Technical Field

[0001] The present invention relates to the technical field of battery welding, and in particular to a welding machine. Background Art

[0002] Button batteries are widely used in our daily lives, especially in small mobile devices such as earphones. During the production of button battery packs, the button battery connector terminals (PINs) and integrated circuit boards (BSBs) need to be assembled and soldered.

The pressure claw assembly comprises a connecting drive block and a fixed pressure claw, wherein the fixed pressure claw is mounted on one end of the connecting drive block, and the other end of the connecting drive block is driven and connected to the lifting drive part. One end of the fixed pressure claw is provided with a positioning groove, and both sides of the fixed pressure claw are provided with welding positioning grooves. When welding is required, the lifting drive part drives the connecting drive block to descend, thereby driving the fixed pressure claw to be fixed to the metal connecting piece to be welded. After the fixed pressure claw is fixed, the laser welding part performs laser welding at the corresponding position of the welding, thereby completing the entire welding process.

[0089] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0090] like Figure 1A specific embodiment of a welding machine shown includes a workbench equipped with a loading section, a positioning compensation section, a welding section, and a discharge section. The loading section is used to transport pre-welded connector terminals and integrated circuit boards to predetermined positions of the welding section and the positioning compensation section, respectively. The positioning compensation section is used to perform flatness inspection on the pre-welded connector terminals and angular position compensation on the integrated circuit board. The welding section 3 is used to weld the position-compensated connector terminals and integrated circuit board and transport them to the discharge section. The loading section and discharge section are located on either side of the welding section 3. In this embodiment, the positioning compensation section is provided between the loading section and the welding section 3, eliminating the need for commissioning personnel to perform additional quality inspections on the connector terminals and integrated circuit board, thereby improving the overall work efficiency of the welding machine. The positioning compensation section also reduces computational complexity, improves compensation accuracy, and ensures welding quality. Furthermore, the loading section, positioning compensation section, welding section 3, and discharge section are coordinated and processed together, allowing commissioning personnel to use this welding machine to debug welding production lines, shortening the debugging cycle and reducing the professional requirements of the commissioning personnel.

[0091] On the basis of the above embodiment, in a preferred embodiment, the feeding part includes a first feeding part 1, such as Figure 1 and Figure 2 As shown, the first loading section 1 includes a first feeding flyer 11, a first pick-up and flipping assembly 12, and a first pick-up and transfer assembly 13. The first feeding flyer 11 has a carrier tape suitable for carrying PINs; the first pick-up and flipping assembly 12 is located below the first feeding flyer 11 and is suitable for removing PINs from the carrier tape of the first feeding flyer 11 and flipping it; the first pick-up and transfer assembly 13 is located to one side of the first pick-up and flipping assembly 12 and is suitable for removing PINs from the first pick-up and flipping assembly 12 and transporting them to the welding section 3. In this embodiment, the first pick-up and flipping assembly 12 first removes the PINs from the carrier tape of the first feeding flyer 11, and the first pick-up and transfer assembly 13 then removes the PINs from the first pick-up and flipping assembly 12 and transports them to the welding station. The first feeding flyer 11, the first pick-up and flipping assembly 12, and the first pick-up and transfer assembly 13 cooperate to complete the loading of PINs, improving the loading efficiency and ensuring the accuracy of PIN loading.

[0092] On the basis of the above embodiment, in a preferred embodiment, two first feeding flyers 11 are provided to achieve non-stop material change of PIN.

[0093] On the basis of the above embodiment, in a preferred embodiment, a first pneumatic scissors is provided below the discharge port of the first feeding flyer 11, which is suitable for cutting the carrier tape to avoid accumulation of the carrier tape output.

[0094] On the basis of the above embodiment, in a preferred embodiment, as Figure 2 and Figure 3 As shown, the first material retrieving and flipping assembly 12 includes a clamping jaw 121, a first cylinder 122, and a rotating platform 123. The clamping jaw assembly 121 includes a pair of opposing first clamping jaws 1211, adapted to approach and grasp a PIN. The first cylinder 122 is connected to the clamping jaw assembly 121 and is adapted to control the reciprocating vertical movement of the clamping jaw assembly 121. The rotating platform 123 is connected to the first cylinder 122 and is adapted to drive the rotation of the first cylinder 122 and the clamping jaw assembly 121. In this embodiment, the first cylinder 122 controls the vertical movement of the first clamping jaw 1211. After the first clamping jaw 1211 removes the PIN from the carrier tape of the first feeding flyer 11, the rotating platform 123 rotates, flipping the PIN so that the first material retrieving and transferring assembly 13 can proceed with subsequent processes.

[0095] On the basis of the above embodiment, in a preferred embodiment, as Figure 2 and Figure 4 As shown, the first material removal and transplanting assembly 13 includes a second clamping jaw 131, a second cylinder 132, and a rotary motor 133. Two second clamping jaws 131 are symmetrically provided, each adapted to remove a PIN from the first clamping jaw 1211 and place it on the welding portion 3. The second cylinder 132 is adapted to drive the second clamping jaw 131 upward and downward. The rotary motor 133 is connected to the second cylinder 132 and adapted to drive the second cylinder 132 and the second clamping jaw 131 in rotation. In this embodiment, after the second clamping jaw 131 removes the PIN from the first clamping jaw 1211, the rotary motor 133 flips the PIN horizontally 180° to align the orientation of the PIN corner pads.

[0096] On the basis of the above embodiment, in a preferred embodiment, the feeding part further includes a second feeding part 2, such as Figure 5 and Figure 6 As shown, the second loading section 2 includes a second feeding assembly 21 and a second transplanting assembly 22. The second feeding assembly 21 includes a second feeding flyer 211 and a second pneumatic scissors 212. The carrier tape of the second feeding flyer 211 is suitable for carrying BSBs. The second pneumatic scissors 212 are arranged below the discharge port of the second feeding flyer 211 and are suitable for cutting the carrier tape.

[0097] On the basis of the above embodiment, in a preferred embodiment, as Figure 5 and Figure 7As shown, the second transfer assembly 22 is positioned above the second feed flyer 211. The second transfer assembly 22 includes a transfer driver 221 and a suction member 222. The transfer driver 221 is connected to the suction member 222, driving the suction member 222 in linear reciprocating motion. The suction member 222 is adapted to grasp BSBs. In this embodiment, the second transfer assembly 22 removes BSBs from the carrier tape of the second feed flyer 211 and transfers them to the second compensation unit 5 for position compensation.

[0098] On the basis of the above embodiment, in a preferred embodiment, as Figure 7 and Figure 8 As shown, the suction member 222 includes a vacuum solenoid valve 2221 and a third suction block 2222. The third suction block 2222 is provided with a first boss 2223. The first boss 2223 defines an air channel that connects to the interior of the third suction block 2222. The vacuum solenoid valve 2221 is connected to the third suction block 2222 and is suitable for controlling the air pressure within the air channel. In this embodiment, the vacuum solenoid valve 2221 and the third suction block 2222 are connected to achieve negative pressure suction, thereby smoothly adsorbing the BSB onto the first boss 2223 for subsequent position compensation.

[0099] Based on the above embodiment, in a preferred embodiment, the shape of the first boss 2223 is the same as that of the BSB, and the size of the first boss 2223 is not larger than that of the BSB. In this embodiment, the shape and size of the first boss 2223 are set to facilitate entering the groove of the carrier tape of the second feeding flyer 211 to retrieve the material.

[0100] On the basis of the above embodiment, in a preferred embodiment, the positioning compensation unit includes a detection unit 4, such as Figure 9 As shown, the inspection unit 4 includes a shaping assembly 41 and a first image sensor 42. The shaping assembly 41 includes two symmetrical shaping blocks 411 and sliders 412. The sliders 412 are controlled by a driver and are adapted to drive the shaping blocks 411 toward and compress the PIN. The first image sensor 42 is positioned on one side of the shaping assembly 41 and is adapted to inspect the flatness of the shaped PIN. In this embodiment, the shaping blocks 411 first press and shape the PIN, while the first image sensor 42 inspects the flatness of the shaped PIN. This avoids waste of BSBs due to substandard PIN quality, improves the BSB soldering yield, and reduces the reject rate.

[0101] Based on the above embodiment, in a preferred embodiment, the shaping assembly 41 further includes a spring connecting the shaping block 411 and the slider 412. In this embodiment, the spring provides a certain amount of dynamic buffering for the shaping block 411, thereby preventing damage to the PIN caused by the downward pressure of the shaping block 411.

[0102] On the basis of the above embodiment, in a preferred embodiment, the positioning compensation part further includes a compensation part 5, and the compensation part 5 includes an initial positioning compensation component 51, such as Figure 10 As shown, the initial positioning compensation assembly 51 includes a vacuum nozzle connector 511, a first suction block 512, and a compensation platform 513. The first suction block 512 is connected to the vacuum nozzle connector 511 and has an internal gas channel. The vacuum nozzle connector 511 has a vacuum hole that communicates with the gas channel. The BSB is placed at the vacuum hole. The vacuum nozzle connector 511 is connected to an external vacuum pump to absorb and secure the BSB. The compensation platform 513 is fixed to the bottom of the first suction block 512 and is suitable for horizontal movement to adjust the position of the first suction block 512.

[0103] On the basis of the above embodiment, in a preferred embodiment, the initial positioning compensation component 51 further includes a second image sensor, and light-transmitting holes are provided on the side walls and top walls of the first suction block 512. Light passes through the light-transmitting holes on the side walls and top walls of the first suction block 512 in turn and shines on the BSB, and the second image sensor takes pictures to detect the position of the BSB.

[0104] On the basis of the above embodiment, in a preferred embodiment, the BSB compensation part 5 further includes a pressed coaxial compensation component 52, such as Figure 11 and Figure 12 As shown, the coaxial compensating assembly 52 comprises a drive mechanism 521, a second suction block 522, and two pressure claws 523. The second suction block 522 is used to secure the BSB at a predetermined position on the positioning compensation section by suction. The two pressure claws 523 are symmetrically positioned on either side of the second suction block 522, and the pressure claws 523 are rotated by the drive mechanism 521. In this embodiment, the drive mechanism 521 adjusts the posture of the pressure claws 523 to compensate for the angular position of the BSB, providing coaxial compensation for the BSB and enabling coaxial welding of PIN and BSB. Therefore, when calculating the compensation value, the influence of the rotational radius of the rotating axis on the calculated result can be reduced, reducing the computational complexity, improving compensation accuracy, and ensuring weld quality.

[0105] In a preferred embodiment, based on the above embodiment, compensation unit 5 further includes a multi-axis servo platform 53, which is fixed to the pressed coaxial compensation assembly 52 and is suitable for controlling the linear movement of the pressed coaxial compensation assembly 52. ​​In this embodiment, the linear dimensional position of the BSB is first compensated by the multi-axis servo platform 53, and the angular position of the BSB is compensated by the pressed coaxial compensation assembly 52, thereby ensuring the welding accuracy of the PIN and BSB.

[0106] On the basis of the above embodiment, in a preferred embodiment, as Figure 12As shown, a pressing boss 5231 is provided on the pressing claw 523, and the pressing boss 5231 is suitable for pressing the PIN and BSB together with the clamping and positioning assembly 32 so that the welding machine can weld the PIN and BSB.

[0107] On the basis of the above embodiment, in a preferred embodiment, as Figure 16 As shown, the multi-axis servo platforms 53 are a pair symmetrically arranged on either side of the two sets of second feeder flyers 211, each including a first direction module 531, a second direction module 532, and a third direction module 533. In this embodiment, the multi-axis servo platforms 53 are symmetrically arranged on either side of the two sets of second feeder flyers 211, which allows one channel to be in the welding position while the other channel takes a BSB photo and compensates for the angle and synchronously completes the welding waiting position, thereby achieving the purpose of improving the welding standard parts and thus improving the positive electrode standard parts.

[0108] On the basis of the above embodiment, in a preferred embodiment, as Figure 13 As shown, the welding section 3 comprises a turntable 31, multiple sets of clamping and positioning assemblies 32, and a welding machine. The turntable 31 is rotatably mounted on a workbench. The first loading section 1, the detection section 4, the second loading section 2, and the compensation section 5 are sequentially arranged around the outer periphery of the turntable 31. Multiple sets of clamping and positioning assemblies 32 are arranged on the turntable 31 at equal intervals around the circumference. The clamping and positioning assemblies 32 are adapted to clamp pins. In this embodiment, each clamping and positioning assembly 32 is used to clamp a pin, which is then transported to the bottom of the welding machine via the turntable 31. After welding is completed, the turntable 31 continues to rotate, transporting the next pin to the bottom of the welding machine.

[0109] On the basis of the above embodiment, in a preferred embodiment, as Figure 14As shown, the first direction is the X direction, the second direction is the Y direction, and the third direction is the Z direction. The clamping and positioning assembly 32 includes a first clamping block 321, a second reference block 322, a second clamping block 323, a third reference block 324, and a linear guide.

In this embodiment, the PIN is clamped in the X, Y, and Z directions to achieve precise positioning of the PIN, and the first clamping block 321, the second clamping block 323, and the third reference block 324 can be independently adjusted in position to ensure that the first clamping block 321, the second clamping block 323, and the third reference block 324 avoid the terminal protection cover to avoid deformation of the PIN due to the clamping blocks hitting the terminal protection cover. When the PIN is clamped, the third reference block 324 is driven by the linear guide to separate from the PIN, thereby achieving the effect of not affecting the height of the PIN and improving the welding yield.

[0110] On the basis of the above embodiment, in a preferred embodiment, as Figure 15 As shown, the thickness of the head of the first clamping block 321 is 0.4 mm.

[0111] On the basis of the above embodiment, in a preferred embodiment, the first clamping block 321 , the second clamping block 323 , the second reference block 322 and the third reference block 324 are all made of black zirconium oxide material.

[0112] Based on the above embodiment, in a preferred embodiment, the welding part 3 also includes a lifting and unloading assembly 33 connected to the clamping and positioning assembly 32. The lifting and unloading assembly 33 has a first driving member and a second driving member respectively connected to a pair of first clamping blocks 321 and a second clamping block 323. The first driving member and the second driving member are suitable for controlling the movement of the first clamping block 321 and the second clamping block 323.

[0113] Before welding, the first feeding flyer 11 transports the PIN, and the first cylinder 122 controls the first clamp 1211 to move up and down. After the first clamp 1211 takes the PIN out of the carrier tape of the first feeding flyer 11, the turntable 123 rotates to flip the PIN; after the second clamp 131 takes the PIN out of the first clamp 1211, the rotating motor 133 flips it horizontally 180° to make the direction of the PIN corner pad consistent. When the PIN is in the appropriate position, the second cylinder 132 controls the second clamp 131 to move up and down to place the PIN on the clamping positioning assembly 32 (that is, the predetermined position of the welding part).

[0114] During the operation of the first feeding flyer 11, the first pneumatic scissors are controlled by real-time monitoring to cut the carrier tape to avoid accumulation of the carrier tape output.

[0115] After the first clamping block 321, the second reference block 322, the second clamping block 323 and the third reference block 324 position and clamp the PIN in the X, Y and Z directions, the third reference block 324 is driven by the linear guide to separate from the PIN. After the PIN positioning and clamping work is completed, the shaping block 411 first presses and shapes the PIN, and the first image sensor 42 performs flatness detection on the shaped PIN. If the PIN flatness detection fails, it is determined to be a non-welded BSB, and the unqualified PIN is discharged by the defective discharge mechanism.

[0116] The second loading part 2 operates simultaneously with the first loading part 1, the second feeding flyer 211 transports the BSB, the vacuum solenoid valve 2221 is connected to the third suction block 2222 to achieve negative pressure adsorption, and enters the groove of the second feeding flyer 211 to take out the BSB.

[0117] The transplanting drive 221 controls the movement of the third suction block 2222, placing the BSB on the first suction block 512 for initial positioning compensation. After negative pressure is generated in the gas channel through the vacuum nozzle connector 511 to fix the BSB by suction, the compensation platform 513 moves in the horizontal direction to adjust the position of the first suction block 512. After the position of the first suction block 512 is adjusted, the second image sensor takes a photo to detect the position of the BSB.

[0118] After the initial positioning compensation of the BSB is completed, the second suction block 522 takes the BSB out of the first suction block 512. The driving mechanism 521 compensates for the angular position of the BSB by adjusting the posture of the pressure claw 523. Then the multi-axis servo platform 53 compensates for the linear dimension position of the BSB so that the BSB is in the welding position. The welding machine welds the PIN and BSB. After welding is completed, the welded product is transported by the unloading part.

[0119] During the welding process, the turntable 31 rotates to send the PIN to the bottom of the welding machine. After the welding is completed, the turntable 31 continues to rotate to send the next PIN to the bottom of the welding machine, and the welding work is completed in sequence.

[0120] 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 readily appreciate that other variations or modifications based on the above descriptions are possible. 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.
