[0022] This invention proposes a capacitor core assembly device 100.

[0023] Please see Figures 1-2In one embodiment of the present invention, the capacitor core assembly device 100 includes a transport module 1, a capacitor assembly module 4, a spacer assembly module 5, a solder pad assembly module 6, a lead wire assembly module 8, and two dispensing modules 7. The transport module 1 includes a turntable 11, on which six assembly stations are spaced apart along its rotation direction. The six assembly stations are, in sequence, a first station 111, a second station 112, a third station 113, a fourth station 114, a fifth station 115, and a sixth station 116. Position 116; An assembly fixture 2 is provided on the top of the turntable 11, and the turntable 11 is used to drive the assembly fixture 2 to move sequentially to each assembly station along the rotation direction; A capacitor assembly module 4 is provided corresponding to the first station 111, and the capacitor assembly module 4 is used to place at least one capacitor on the assembly fixture 2 located at the first station 111, and to place multiple capacitors at radial intervals along the turntable 11 when loading and placing the capacitor; A spacer assembly module 5 is provided corresponding to the second station 112, and the spacer assembly module 5 is used to assemble the capacitors at the second station 112. When the jig 2 contains multiple capacitors, a spacer is placed between any two adjacent capacitors on the assembly jig 2; the solder pad assembly module 6 is set corresponding to the fourth station 114, and the solder pad assembly module 6 is used to load two solder pads into the assembly jig 2 located at the fourth station 114, and the two electrodes of each capacitor are in contact with the two solder pads respectively; the two dispensing modules 7 are the first dispensing module 7a and the second dispensing module 7b, respectively, and the first dispensing module 7a and the second dispensing module 7b are both set on the top of the turntable 11 and correspond to the third station respectively. The assembly fixture 113 and the fifth station 115 are set up; the first dispensing module 7a is used to apply flux to the electrodes of the capacitor in the assembly fixture 2 located in the third station 113; the second dispensing module 7b is used to apply flux to the solder pads in the assembly fixture 2 located in the fifth station 115; the lead assembly module 8 is set up corresponding to the sixth station 116, and the lead assembly module 8 is used to insert two leads into the assembly fixture 2 located in the sixth station 116, and the two leads are respectively located on the side of the two solder pads away from the capacitor, so as to assemble a capacitor core assembly.

[0024] The capacitor assembly apparatus 100 of the present invention has six assembly stations arranged on a turntable 11 along its rotation direction. A capacitor assembly module 4 is provided corresponding to the first station 111. The capacitor assembly module 4 is used to place capacitors onto the assembly fixture 2 located at the first station 111, and the capacitor assembly module 4 can place different numbers of capacitors on the assembly fixture 2 according to the specifications of the capacitor core assembly to be assembled. A spacer assembly module 5 is provided corresponding to the second station 112. The spacer assembly module 5 is used to place spacers between any two adjacent capacitors when multiple capacitors are placed on the assembly fixture 2, thereby separating the two adjacent capacitors to avoid mutual interference. A first dispensing module 7a is provided corresponding to the third station 113. The first dispensing module 7a is used to apply flux to the electrodes of the capacitors and... The fourth station 114 is equipped with a solder pad assembly module 6. After flux is applied to the capacitor electrodes, the solder pad assembly module 6 aligns the solder pads with the capacitor electrodes for assembly. The flux facilitates subsequent soldering and also helps to adhere the solder pads to the capacitor electrodes, preventing them from falling off during transport via the turntable 11. The fifth station 115 is equipped with a second dispensing module 7b, and the sixth station 116 is equipped with a lead wire assembly module 8. The second dispensing module 7b is used to apply flux to the side of the solder pad away from the capacitor, and the lead wire assembly module 8 is used to assemble the lead wires on the side of the solder pad away from the capacitor. The flux applied to the solder pads not only facilitates subsequent soldering of the solder pads and leads, but also has a certain degree of adhesion, which can adhere the lead wires to the solder pads and prevent them from falling off. Therefore, the capacitor core assembly device 100 of the present invention, compared with the manual assembly method, not only realizes the automatic assembly of capacitor cores, greatly improving the assembly efficiency and yield of capacitor cores, but also can assemble capacitor cores with different numbers of capacitors, making it more versatile.

[0025] Understandably, when assembling a capacitor core assembly with only a single capacitor, the spacer assembly module 5 does not participate in the assembly work. When assembling a capacitor core assembly with multiple capacitors, the capacitor assembly module 4 first places the multiple capacitors sequentially and at intervals on the assembly fixture 2 to facilitate the subsequent assembly of the spacers. All capacitors are placed in the same direction, with the positive terminals on the same side and the negative terminals on the other side; all positive terminals are in contact with the same solder pad, and all negative terminals are in contact with the same solder pad.

[0026] It should be noted that, Figure 11 (a) is a capacitor core assembly 200 consisting of a single capacitor, which includes a capacitor 201, two solder pads 203 and two leads 204. The two solder pads 203 are respectively connected to the two electrodes of the capacitor 201, and the two leads 204 are respectively connected to the side of the two solder pads 203 away from the capacitor 201. Figure 11(b) is a capacitor core assembly 200 consisting of multiple capacitors 201, including capacitors 201, spacers 202, two solder pads 203 and two leads 204. A spacer 202 is provided between any two adjacent capacitors 201. The two solder pads 203 are respectively connected to the two electrodes of each capacitor 201. The two leads 204 are respectively connected to the side of the two solder pads 203 away from the capacitors 201.

[0027] Please see Figure 4 and Figure 5 In one embodiment, the assembly fixture 2 includes a base 21 and a rotating rod 22. The rotating rod 22 is rotatably connected to the top of the base 21 and extends radially along the turntable 11. The top of the rotating rod 22 is provided with an assembly groove 221 for assembling capacitor cores. A sliding groove 222 communicating with the assembly groove 221 is provided on the rotating rod 22 and on one side of the assembly groove 221. A top rod 23 is provided in the sliding groove 222. The top of the base 21 is also provided with a first pushing mechanism 24. The first pushing mechanism 24 is used to push the top rod 23 toward the end of the assembly groove 221 into the sliding groove 222 or out of the sliding groove 222, so that the capacitor placed in the assembly groove 221 is clamped or released by the cooperation of the top rod 23 and the side wall of the assembly groove 221 away from the sliding groove 222.

[0028] Understandably, the assembly fixture 2 is provided with a rotating rod 22, and the top of the rotating rod 22 is provided with an assembly groove 221. During the assembly process, the capacitor, separator, solder pad and lead wire are all assembled in the assembly groove 221. The rotating rod 22 is also provided with a sliding groove 222 on one side of the assembly groove 221. A push rod 23 is provided in the sliding groove 222. By providing a first pushing mechanism 24 on the base 21, the first pushing mechanism 24 can push the push rod 23 into the assembly groove 221, thereby pressing the capacitor placed in the assembly groove 221.

[0029] It should be noted that when assembling a capacitor core assembly consisting of a single capacitor, the capacitor can be pressed into the assembly slot 221 by the push rod 23 after the capacitor is inserted into the assembly slot 221. When assembling a capacitor core assembly consisting of multiple capacitors, after placing a spacer between any two adjacent capacitors, since the multiple capacitors are placed radially spaced along the turntable 11, the slide 222 extends radially along the turntable 11, and the push rod 23 also moves radially along the turntable 11, the multiple capacitors can also be pressed into the assembly slot 221 by the push rod 23.

[0030] Please combine Figure 2 , Figure 4 and Figure 5 In one embodiment, a cam 12 is provided at the top center of the turntable 11, and the turntable 11 rotates relative to the cam 12. The first dispensing module 7a and the second dispensing module 7b are both provided on the top of the cam 12.

[0031] Furthermore, the first pushing mechanism 24 includes a locking rod 241, a locking block 242, and a first elastic element (not shown in the figure). The locking rod 241 is slidably connected to the base 21 and extends radially along the turntable 11. One end of the locking rod 241 abuts against the cam 12. The locking block 242 is connected to the end of the locking rod 241 away from the cam 12. A limiting block 231 is provided at the top of the push rod 23, and the limiting block 231 extends out of the slide groove 222. The locking block 242 is located on the side of the limiting block 231 away from the cam 12 and abuts against the limiting block 231. The first elastic element is provided in the slide groove 222 and is located on the side of the push rod 23 near the cam 12. The two ends of the first elastic element abut against the push rod 23 and the groove wall of the slide groove 222, respectively.

[0032] Understandably, by setting the locking rod 241, which abuts against the cam 12, the locking rod 241 slides relative to the base 21 when it abuts against the cam 12 at different positions, thereby driving the locking block 242 to slide. When the locking rod 241 slides away from the cam 12, the locking block 242 moves closer to the mounting groove 221, causing the push rod 23 to extend into the mounting groove 221 under the elastic force of the first elastic element. When the locking rod 241 slides towards the cam 12, the locking block 242 drives the limiting block 231 to slide away from the mounting groove 221, thereby driving the push rod 23 to extend out of the mounting groove 221, while compressing the first elastic element.

[0033] Please combine Figure 4 and Figure 5 In one specific embodiment, a first hinge seat 243 is provided at one end of the locking rod 241 that abuts against the cam 12. A first roller 244 that rolls in contact with the outer edge of the cam 12 is hinged to the first hinge seat 243. When the turntable 11 drives the assembly fixture 2 to move in the rotation direction, the first roller 244 rolls along the outer edge of the cam 12. A second elastic element 245 is sleeved on the locking rod 241, and both ends of the second elastic element 245 abut against the base 21 and the first hinge seat 243, respectively. By setting the first roller 244 to contact the outer edge of the cam 12, frictional resistance is reduced; and through the second elastic element 245, it is ensured that the second roller 272 is always in contact with the outer edge of the cam 12, so that when the second roller 272 abuts against the cam 12 at different positions, it slides relative to the base 21 in the corresponding direction.

[0034] Furthermore, the outer edge of the cam 12 is provided with a mating area that can abut against the locking rod 241, and the mating area extends along the rotation direction of the turntable 11; the position of the mating area corresponding to the third station 113 to the sixth station 116 is a mating part that abuts against the push rod 27; when the locking rod 241 abuts against the mating part, the push rod 23 extends into the assembly groove 221; when the locking rod 241 abuts against the other positions on the mating area except for the mating part, the push rod 23 extends out of the assembly groove 221.

[0035] Understandably, the push rod 23 does not extend into the assembly slot 221 during the first station 111 to the second station 112, mainly to facilitate the assembly of capacitors and spacers. During the third station 113 to the sixth station 116, the push rod 23 presses the capacitors together, which can prevent the capacitors from shaking when applying flux. When assembling a capacitor core group composed of multiple capacitors, it can also make the spacers and capacitors fit more closely and without gaps. Furthermore, clamping the capacitors also helps to prevent the capacitors from shaking when assembling solder pads and leads, thus improving the yield of finished products.

[0036] Please combine Figure 2 , Figure 4 and Figure 5 In one embodiment, two clamping blocks 25 are slidably disposed on the top of the base 21, and the two clamping blocks 25 are respectively located on opposite sides of the assembly groove 221 along the circumference of the turntable. Each clamping block 25 has a protrusion on the top of the side facing the assembly groove 221. A first mounting groove 211 is opened at the bottom of the base 21, and the bottom of each clamping block 25 extends into the first mounting groove 211. A second pushing mechanism 26 is disposed in the first mounting groove 211. A push rod 27 that can slide radially along the turntable 11 is disposed on the side of the base 21 facing the cam 12. One end of the push rod 27 facing the cam 12 slides against the cam 12, and the other end of the push rod 27 away from the cam 12 extends into the first mounting groove 211 and is connected to the second pushing mechanism 26.

[0037] Understandably, by providing two clamping blocks 25 on the top of the base 21, with the two clamping blocks 25 located on opposite sides of the assembly groove 221 along the circumference of the turntable, the protrusions on the clamping blocks 25 can extend into the assembly groove 221. Through the cooperation of the two protrusions, the capacitor can be clamped and centered in the assembly groove 221. Furthermore, when multiple capacitors are placed in the assembly groove 221, the two protrusions can cooperate to align the multiple capacitors, ensuring that the multiple capacitors are aligned and improving assembly accuracy. By providing a second pushing mechanism 26 and a push rod 27 on the base 21, one end of the push rod 27 abuts against the cam 12. When the push rod 27 abuts against the cam 12 at different positions, it slides relative to the base 21, and through the second pushing mechanism 26, it drives the two clamping blocks 25 to move closer or further away from each other, so that the protrusions extend into or out of the assembly groove 221.

[0038] It should be noted that the push rod 27 and the locking rod 241 are spaced apart in the vertical direction, so that they abut against different positions on the cam 12 respectively.

[0039] Furthermore, the outer edge of the cam 12 is provided with an abutment area that can abut against the push rod 27, and the abutment area extends along the rotation direction of the turntable 11; the abutment area forms a recess that abuts against the push rod 27 at the positions between the first station 111 and the second station 112, the positions between the second station 112 and the third station 113, the positions between the fourth station 114 and the fifth station 115, and the positions after the sixth station 116; wherein, when the push rod 27 abuts against the recess, the second pushing mechanism 26 pushes the two clamping blocks 25 closer to each other so that each protrusion extends into the assembly groove 221; when the push rod 27 abuts against the other positions on the abutment area except for the recess, the second pushing mechanism 26 pushes the two clamping blocks 25 away from each other so that each protrusion extends out of the assembly groove 221.

[0040] Understandably, the contact area extends along the rotation direction of the turntable 11, and recesses that abut against the push rod 27 are formed at positions corresponding to the first station 111 to the second station 112, the second station 112 to the third station 113, the fourth station 114 to the fifth station 115, and positions after the sixth station 116. Understandably, when assembling a capacitor at the first station 111, the protrusion is outside the assembly groove 221; at positions between the first station 111 and the second station 112, the push rod 27 abuts against the recesses, and the protrusion extends into the assembly groove 221 to center the capacitor; when assembling a spacer at the second station 112, the protrusion is outside the assembly groove 221; at positions between the second station 112 and the third station 113, the protrusion extends into the assembly groove 221 to center the capacitor and spacer, so that the capacitor and spacer are aligned with each other; at the sixth station 112, the protrusion abuts against the push rod 27. At station 113, the protrusion is outside the assembly slot 221, facilitating the application of flux to the capacitor's motor. Between stations 113 and 114, and at station 114, the protrusion remains outside the assembly slot 221 to prevent it from scratching the flux, thus facilitating the assembly of solder pieces. Between stations 114 and 115, after the solder pieces are assembled, the protrusion extends into the assembly slot 221, pressing the two solder pieces firmly onto the two electrodes of the capacitor, ensuring full contact and adhesion between the solder pieces and the flux. Between stations 115 and 116, the protrusion extends out of the assembly slot 221, facilitating further application of flux to the solder pieces and attachment of leads to the outer side of the solder pieces. A protrusion is also provided after station 116, allowing the leads to be clamped onto the solder pieces after lead assembly, ensuring full contact between the leads and the flux applied to the solder pieces.

[0041] Therefore, by cooperating with the cam 12 and the push rod 27, the two clamping blocks 25 can be driven to move away from or move closer to each other through the second push mechanism 26 during the process of transporting the assembly fixture 2 on the turntable 11, so as to achieve the centering positioning of the capacitor, the clamping of the solder sheet and the clamping of the lead wire. No additional power source such as the electric push rod 27 is required, which reduces energy consumption, saves costs, and improves the assembly accuracy and yield of finished products.

[0042] Please see Figure 5 Furthermore, the second pushing mechanism 26 includes a push block 261 and two first springs (not shown in the figure). The push block 261 is disposed in the first mounting groove 211, and the opposite sides of the push block 261 abut against the two clamping blocks 25 respectively. The end of the push rod 27 away from the cam 12 extends into the first mounting groove 211 and is connected to the push block 261. The distance between the opposite sides of the push block 261 gradually decreases from the end near the push rod 27 to the other end. The side of each clamping block 25 away from the push block 261 abuts against the groove wall of the first mounting groove 211 through the first spring.

[0043] Understandably, by providing a push block 261 between the two clamping blocks 25, when the push rod 27 abuts against the cam 12 and slides away from the cam 12, the push rod 27 drives the push block 261 to slide, causing the push block 261 to push the two clamping blocks 25 away from each other and compress the first spring; when the push rod 27 slides toward the cam 12, the push block 261 retracts from the two clamping blocks 25, and under the elastic restoring force of the corresponding first spring, the two clamping blocks 25 move closer to each other.

[0044] In one specific embodiment, a second hinge seat 271 is provided at one end of the push rod 27 that abuts against the cam 12. A second roller 272 that rolls in contact with the outer edge of the cam 12 is mounted on the second hinge seat 271. When the turntable 11 drives the assembly fixture 2 to rotate, the second roller 272 rolls along the outer edge of the cam 12. A second spring 273 is sleeved on the push rod 27, and both ends of the second spring 273 abut against the base 21 and the second hinge seat 271, respectively. Through the elastic force of the second spring 273, it can be ensured that the second roller 272 is always in contact with the outer edge of the cam 12. Therefore, the second spring 273 on the push rod 27 is mainly used to drive the push rod 27 to slide toward the cam 12, thereby causing the push block 261 to retract from the two clamping blocks 25. During the retraction of the push block 261, the two clamping blocks 25 move closer to each other under the action of the two first springs.

[0045] Please combine Figures 2-5In one embodiment, four rotating modules 3 are further provided around the turntable 11, and the four rotating modules 3 are respectively provided for four assembly stations, namely the third station 113, the fourth station 114, the fifth station 115, and the sixth station 116; each rotating module 3 includes a base 31, a translation mechanism 32, and a rotation mechanism 33. The translation mechanism 32 is disposed on the top of the base 31, and the rotation mechanism 33 is disposed on the top of the translation mechanism 32. The rotation mechanism 33 includes a rotation drive component 33. 1 and a rotating shaft 332 connected to the rotating drive 331, the rotating shaft 332 having a locking block 333 at one end facing the turntable 11 that can engage with the rotating rod 22; each rotating module 3 is used to drive the rotating mechanism 33 on its top to translate when the assembly fixture 2 is located at the corresponding assembly station, so that the locking block 333 engages or disengages from the rotating rod 22 of the assembly fixture 2; and is also used to drive the rotating rod 22 to rotate through the rotating shaft 332 of the rotating mechanism 33 when the locking block 333 engages with the rotating rod 22.

[0046] Four rotating modules 3 are arranged around the turntable 11, and the four rotating modules 3 are respectively set for the third station 113, the fourth station 114, the fifth station 115 and the sixth station 116. Each rotating module 3 includes a translation mechanism 32 and a rotation mechanism 33. A locking block 333 that can engage with the rotating rod 22 is provided on the rotation shaft 332 of the rotation mechanism 33. When the assembly fixture 2 is located at any of the four assembly stations, the corresponding rotating module 3 drives the rotating rod 22 on the assembly fixture 2 to rotate, thereby adjusting the angle of the capacitor.

[0047] Understandably, when assembly fixture 2 is at the third station 113, the corresponding rotary module 3 drives the rotating rod 22 to rotate, so that one end electrode of the capacitor faces upward, facilitating the application of flux to the capacitor electrode through the first dispensing module 7a. The rotary module 3 drives the rotating rod 22 to rotate in different directions, so that flux is applied to both ends of the capacitor electrode through the first dispensing module 7a. When assembly fixture 2 is at the fourth station 114, the corresponding rotary module 3 drives the rotating rod 22 to rotate, again so that both ends of the capacitor face upward, facilitating the assembly of solder pads. When assembly fixture 2 is at the fifth station 115, the corresponding rotary module 3 drives the rotating rod 22 to rotate, so that the solder pad faces upward, facilitating the application of flux to the solder pad. When assembly fixture 2 is at the sixth station 116, the corresponding rotary module 3 drives the rotating rod 22 to rotate, so that the solder pad faces upward, facilitating the assembly of leads on the outside of the solder pad. Therefore, by setting up four rotating modules 3, it is beneficial to assemble flux, solder pads and leads, and also improves assembly efficiency and accuracy.

[0048] Furthermore, during the rotation of the rotating module 3 and the rotating gripper, the aforementioned push rod 23 presses the capacitor against the assembly slot 221, preventing the capacitor from shaking or shifting.

[0049] It should be noted that the rotary drive component 331 can be a drive motor in the prior art, and the translation mechanism 32 can be a drive cylinder in the prior art.

[0050] In one embodiment, in each rotating module 3, the top of the translation mechanism 32 is further provided with a vertically extending mounting plate 34. A pin 35 is provided on the side of the mounting plate 34 facing the turntable 11. A rotation drive 331 is located on the side of the mounting plate 34 away from the turntable 11, and a rotation shaft 332 is rotatably inserted through the mounting plate 34. Two locking blocks 28 are slidably provided on the top of the base 21, and the two locking blocks 28 respectively abut against the opposite sides of the rotating rod 22 and cooperate to clamp the rotating rod 22. A second mounting groove 212 is opened at the bottom of the base 21, and the bottom of each locking block 28 extends into the second mounting groove. Inside the mounting slot 212, the base 21 has an insertion hole 213 on the radial outer side of the turntable 11 that communicates with the second mounting slot 212. A gap is formed between the bottoms of the two locking blocks 28. The insertion hole 213 is set to correspond to the gap, and the gap gradually narrows from one end near the insertion hole 213 to the other end. Each rotating module 3 is also used to drive the pin 35 on its top to translate through the translation mechanism 32 when the assembly fixture 2 is located at the corresponding assembly station. This causes the pin 35 to pass through the insertion hole 213 and extend into the gap to abut against the two locking blocks 28, thereby pushing the two locking blocks 28 away from each other to release the rotating rod 22.

[0051] Understandably, by providing two locking blocks 28 on the top of the base 21, the two locking blocks 28 cooperate to clamp the rotating rod 22, which can prevent the rotating rod 22 from rotating outside during the transportation of the assembly fixture 2 by the turntable 11; by providing a pin 35 on the top of the translation mechanism 32 in the rotating module 3, when it is necessary to rotate the rotating rod 22 by the rotating mechanism 33, the pin 35 first extends into the second mounting groove 212 and pushes the two locking blocks 28 away from each other, thereby releasing the rotating rod 22.

[0052] Furthermore, a third spring 281 is provided on one side of each locking block 28 away from the gap. The elastic restoring force of the two third springs 281 causes the two locking blocks 28 to move closer to each other after the pin 35 retracts from the second mounting groove 212, thereby clamping the rotating rod 22.

[0053] Please see Figure 6In one embodiment, the capacitor assembly module 4 includes a capacitor feeding mechanism 41, a first moving mechanism 42, and a capacitor adsorption head 43.

[0054] By setting a capacitor feeding mechanism 41, the top of the capacitor feeding mechanism 41 has a capacitor feeding slot, and the capacitor feeding mechanism 41 is used to provide capacitors from the capacitor feeding slot; when assembling capacitors onto the assembly fixture 2, the first moving mechanism 42 drives the capacitor adsorption head 43 to move above the capacitor feeding slot, and the capacitor is adsorbed by the capacitor adsorption head 43. The first moving mechanism 42 continues to drive the capacitor adsorption head 43 to move, thereby placing the capacitor on the assembly fixture 2 located at the first station 111.

[0055] It should be noted that the capacitor feeding mechanism 41 can adopt a flexible vibrating feeder in the prior art, which can ensure that the appearance of the capacitor is not damaged.

[0056] Further, the first moving mechanism 42 includes a first translation component 421, a second translation component 422, and a first lifting component 423; wherein the second translation component 422 is disposed on top of the first translation component 421, the first lifting component 423 is disposed on the second translation component 422, and the capacitive suction head 43 is disposed on the first lifting component 423; the first translation component 421 is used to drive the second translation component 422 and the first lifting component 423 to translate, the second translation component 422 is also used to drive the first lifting component 423 to translate, and the first translation component 421 and the second translation component 422 are used to drive the first lifting component 423 to translate in different directions; the first lifting component 423 is used to drive the capacitive suction head 43 to lift.

[0061] In addition, a first positioning camera 45 is provided near the capacitor feeding mechanism 41.

The partition cutting mechanism 51 includes a support plate 511, a roller 512, and a cutting assembly 513. The roller 512 is disposed on one side of the support plate 511 and is used to sleeve the partition roll material. The cutting assembly 513 forms a cutting slit through which one end of the partition roll material passes. The cutting assembly 513 is used to cut the partition roll material to obtain partitions. The second moving mechanism 52 is disposed close to the partition cutting mechanism 51. The gripper 53 is disposed on the second moving mechanism 52 and is used to hold the partitions cut by the cutting assembly. The second moving mechanism 52 is used to drive the gripper 53 to move so as to place the partitions held on the gripper 53 onto the assembly fixture 2 located at the second station 112.

[0063] By setting up a separator cutting mechanism 51, the separator cutting mechanism 51 cuts the separator roll material to obtain separators. The cut separators are then picked up by the gripper 53 driven by the second moving mechanism 52 and placed on the assembly fixture 2 located at the second station 112. By cutting the separators during the assembly process of the capacitor core assembly, separators of the required size can be cut according to the different specifications of the assembled capacitor core assembly, thus improving versatility.

[0064] Understandably, during the cutting process, the end of the spacer roll is first gripped by the gripper 53 and pulled a certain distance relative to the cutting seam. Then, it is cut by the cutting assembly, and the spacer of the required size can be obtained on the gripper 53.

[0065] Furthermore, the second moving mechanism 52 includes a support 521 and a second lifting assembly 522.

The third moving mechanism 62 is used to drive the solder sheet adsorption head 63 to move so as to place the solder sheets adsorbed on the solder sheet adsorption head 63 onto the assembly fixture 2 located at the fourth station 114.

[0068] Understandably, the welding sheet is placed in the welding sheet feeding slot of the welding sheet feeding mechanism 61, and the third moving mechanism 62 drives the welding sheet adsorption head 63 to move above the welding sheet feeding slot. The welding sheet is then adsorbed by the welding sheet adsorption head 63. The third moving mechanism then drives the welding sheet adsorption head 63 to move, and the welding sheet adsorbed on the welding sheet adsorption head 63 is placed on the assembly fixture 2 located at the fourth station 114.

[0069] It should be noted that the welding sheet feeding mechanism 61 can also adopt the flexible vibrating feeder in the prior art, which can ensure that the appearance of the welding sheet is undamaged. The third moving mechanism 62 has the same structure as the first moving mechanism 42, and will not be described in detail here.

[0070] Specifically, the third moving mechanism 62 is equipped with two welding sheet adsorption heads 63, which facilitates the simultaneous adsorption of two welding sheets and improves the assembly efficiency of the welding sheets.

[0072] In addition, a second positioning camera 65 is provided near the solder sheet feeding mechanism 61. The second positioning camera 65 is used to identify the solder sheets adsorbed on the solder sheet adsorption head 63, so that the solder sheet adsorption head 63 can correct the orientation of the solder sheets and facilitate the correct assembly of the solder sheets.

[0073] Please see Figure 9In one embodiment, the lead wire assembly module 8 includes a lead wire feeding mechanism 81, a fourth moving mechanism 82, and a lead wire adsorption head 83. The top of the lead wire feeding mechanism 81 has a lead wire feeding groove for placing the lead wire. The fourth moving mechanism 82 is disposed close to the lead wire feeding mechanism 81. The lead wire adsorption head 83 is disposed on the fourth moving mechanism 82 and is used to adsorb the lead wire. The fourth moving mechanism 82 is used to drive the lead wire adsorption head 83 to move so as to place the lead wire adsorbed on the lead wire adsorption head 83 onto the assembly fixture 2 located at the sixth station 116.

[0074] Understandably, the lead wire is placed through the lead wire feeding groove. The fourth moving mechanism 82 is used to first move the lead wire adsorption head 83 to the top of the lead wire feeding groove, and then adsorb the lead wire through the lead wire adsorption head 83. The fourth moving mechanism 82 then moves the lead wire adsorption head 83 to the assembly fixture 2 located at the sixth station 116, and places the lead wire in the assembly fixture 2.

[0075] It should be noted that the fourth moving mechanism 82 has the same structure as the aforementioned first moving mechanism 42, and will not be described in detail here.

[0076] Specifically, the fourth moving mechanism 82 is equipped with two lead wire adsorption heads 83, which facilitates the simultaneous adsorption of two leads and improves assembly efficiency.

[0077] It should be noted that the lead feeding mechanism 81 can use a vibratory feeder from the prior art, which can ensure that the appearance of the lead is undamaged.

The dispensing head 73 is disposed at the end of the support seat 72 away from the lifting seat 71, and the dispensing head 73 is disposed downwards and used to apply flux. It can be understood that by the lifting seat 71 driving the support seat 72 to rise and fall, the dispensing head 73 is driven to rise and fall, so that the dispensing head 73 contacts or disengages from the electrode of the solder pad or capacitor to apply flux.

[0079] It should be noted that the flux used in this embodiment can be solder paste from the prior art.
