The conveying device 10 is used to convey the mounting seat 300, so that the mounting seat 300 passes through the dispensing device 20, the assembly device 30 and the feeding device 40 in sequence. The dispensing device 20 is used to dispense glue on the assembly position of the conveyed mounting seat 300, so as to bond and fix the capacitor 200. The pin cutting device 50 is used to cut the pin 201 of the capacitor 200, the bending device 60 is used to bend the pin 201 of the capacitor 200 after the pin cutting, and the detection device 70 is used to detect the capacitor 200 after the bending. The transfer device 80 is arranged between the pin cutting device 50, the bending device 60 and the detection device 70, and is used to transfer the capacitor 200 after the pin cutting and the capacitor 200 after the bending. The assembly device 30 is used to assemble the capacitor 200 after the inspection to the mounting seat 300 after the dispensing, and the unloading device 40 is used for the shunt unloading of the mounting seat 300 after the capacitor 200 is assembled.

Among them, the control system is an existing design, and its structure and control principle are well known in the art, so it will not be described in detail here.

[0029] Specifically, in the preferred embodiment of the present application, the glue dispensing device 20 and the leg shearing device 50 are arranged on two opposite sides of the conveying device 10, the leg shearing device 50, the bending device 60 and the detection device 70 are arranged in a straight line along the conveying direction of the conveying device 10, the transfer device 80 is arranged parallel to and spaced apart from the three, and the assembly device 30 and the detection device 70 are arranged in a straight line along a direction perpendicular to the conveying direction of the conveying device 10. The optimization of the layout between the devices makes the structure of the whole machine more compact, and the transfer device 80 and the assembly device 30 only need to move in a straight line, and the moving stroke is shorter, thereby further improving the assembly efficiency.

[0030] See also Figure 1 and Figure 2 The conveying device 10 includes a conveyor belt 11, a feeding mechanism 12 disposed at the input end of the conveyor belt 11, and a return belt 13 disposed beside the conveyor belt 11 and dockable with the conveyor belt 11. The feeding mechanism 12 takes and places the mounting seat 300 at the output end of the previous device into the positioning fixture 400 at the input end of the conveyor belt 11 through the feeding clamp 121. The conveyor belt 11 is used to transport the mounting seat 300 loaded in the positioning fixture 400, and the return belt 13 is used to return the empty positioning fixture 400 at the output end of the conveyor belt 11 to the input end of the conveyor belt 11. When the mounting seat 300 with the capacitor 200 installed in the positioning fixture 400 is taken away by the unloading device 40, the return belt 13 transports the empty positioning fixture 400 to the input end of the conveyor belt 11 in the direction opposite to the conveying direction of the conveyor belt 11, thereby realizing the recycling of the positioning fixture 400.

[0031] Specifically, in order to achieve the docking of the return belt 13 and the conveyor belt 11, the conveyor device 10 also includes a docking mechanism 14 arranged between the return belt 13 and the conveyor belt 11, and the docking mechanism 14 includes a push member 141 arranged at the output end of the return belt 13, the output end and the input end of the conveyor belt 11, and a receiving guide rail 142 arranged between the input end and the output end of the return belt 13 and the conveyor belt 11, wherein one push member 141 can push the positioning fixture 400 located at the output end of the return belt 13 under the drive of the push driver 143 connected thereto, so that it passes through the receiving guide rail 1 42 is pushed to the input end of the conveyor belt 11. Similarly, another pusher 141 can push the empty positioning fixture 400 located at the output end of the conveyor belt 11 under the drive of the push driver 143 connected thereto, so that it is pushed to the input end of the return belt 13 through the receiving guide rail 142. The loading mechanism 12 transfers the mounting seat 300 from the previous device to the positioning fixture 400 located at the input end of the conveyor belt 11, and then the third pusher 141 located here pushes the positioning fixture 400 equipped with the mounting seat 300 onto the conveyor belt 11 for the conveyor belt 11 to be transported. Among them, a sensor 15 is provided at each of the input and output ends of the conveyor belt 11, which is used to sense whether the positioning fixture 400 is discharged, so as to send a signal to the controller, thereby giving the conveyor belt 11 an action instruction. In order to improve the accuracy of dispensing and assembly, a positioning mechanism for positioning the positioning fixture 400 is also provided at the dispensing device 20 and the assembly device 30 on the conveyor belt 11.

[0032] See also Figure 3 The dispensing device 20 includes a dispensing head 21, an X-axis module 23 mounted on a bracket 22, a Y-axis module 24 connected to the output end of the X-axis module 23, and a Z-axis module 25 connected to the output end of the Y-axis module 24. The dispensing head 21 is connected to the output end of the Z-axis module 25. The dispensing head 21 is placed vertically relative to the working platform 101. The dispensing head 21 can move linearly along the X-axis, Y-axis and Z-axis directions under the drive of the X-axis module 23, the Y-axis module 24 and the Z-axis module 25, so as to realize dispensing of two assembly positions in the mounting seat 300. Preferably, in the conveying direction, an ion blower for cleaning is also provided on the front side of the dispensing device 20, so that cleaning is performed before dispensing, and the dispensing effect is better.

[0033] See also Figure 4 and Figure 5The pin-cutting device 50 includes a cutting table 51, a cutting cylinder 52 disposed above the cutting table 51, and a cutter 53 connected to the output end of the cutting cylinder 52. The cutting table 51 is used to carry the capacitor 200 transmitted to its table, so that the pin 201 of the capacitor 200 is located directly below the cutter 53. The cutting cylinder 52 can drive the cutter 53 to move up and down in a straight line to cut the pin 201. Specifically, in order to improve efficiency, in the preferred embodiment of the present application, the pin-cutting device 50 can cut the pins 201 of two capacitors 200 each time, and the cutter 53 is rectangular, and two capacitors 200 can be moved to the bottom of the cutter 53 each time. Further, in order to improve the precision of cutting, in other embodiments, before the cutter 53 punches the pin 201, the cutter seat 54 used to fix the cutter 53 can be firstly pressed with the cutting table 51, so as to fix the capacitor 200 transmitted on the material belt, and then the cutter 53 performs the cutting operation. Of course, a crimping piece 55 may also be provided to fix the capacitor 200 transmitted on the material tape.

[0034] It should be noted that when the capacitor 200 is loaded in the form of a roll, the capacitor assembly machine 100 of the present invention also includes a feeding device 90, which includes a discharge tray 91, a spacer paper receiving tray 92 and a sticker receiving tray 93. Multiple capacitors 200 are evenly distributed between the spacer paper and the sticker to form a material strip 202. The material strip 202 is rolled into a roll and loaded on the discharge tray 91. The free end of the material strip 202 is wound around the guide wheel, the tensioning wheel, and the shearing table 51 of the shearing foot device 50 and then connected to the spacer paper receiving tray 92. After the capacitor 200 is taken away, the spacer paper is wound on the spacer paper receiving tray 92, and the sticker is separated from the spacer paper and wound on the sticker receiving tray 93. When the spacer paper receiving tray 92 rotates, the material strip 202 can be pulled, so that the capacitors 200 on the material strip 202 are wound around the shearing table 51 in turn, and the distance of 1 or 2 capacitors 200 can be wound each time.

[0035] See also Figure 6 The transfer device 80 includes a pick-and-place mechanism 81 and a pick-and-place mechanism 82 arranged in parallel and at intervals. The spacing between the pick-and-place mechanism 81 and the pick-and-place mechanism 82 corresponds to the spacing between the foot-cutting device 50 and the bending device 60. In order to improve efficiency, the transfer device 80 can transfer two capacitors 200 each time. Then the pick-and-place mechanism 81 and the pick-and-place mechanism 82 both include two transfer jaws 83 arranged side by side. The pick-and-place mechanism 81 and the pick-and-place mechanism 82 can drive the two transfer jaws 83 connected thereto to move linearly along the X-axis direction and the Z-axis direction, thereby respectively transferring the capacitor 200 after the foot is cut and the capacitor 200 after the bending. Specifically, the pick-and-place mechanism 81 disposed between the foot-cutting device 50 and the bending device 60 is used for transferring the capacitor 200 after the foot is cut, and the pick-and-place mechanism 82 disposed between the bending device 60 and the detection device 70 is used for transferring the capacitor 200 after the bending. Of course, in other embodiments, only one transfer jaw 83 can be provided in each pick-and-place mechanism.

[0036] In the preferred embodiment of the present application, the transfer device 80 can synchronously transfer the two capacitors 200 after the shearing and the two capacitors 200 after the bending, so the spacing between the shearing device 50 and the bending device 60 and between the bending device 60 and the detection device 70 can be equal, and the spacing between the pick-up and placement mechanism 81 and the pick-up and placement mechanism 82 corresponds thereto. Specifically, the pick-up and placement mechanism 81 includes an X-axis module 811 installed at the lower end of the bracket 84, a Z-axis module 812 connected to the output end of the X-axis module 811, and two clamping drivers 813 connected to the output end of the Z-axis module 812, and the output ends of the two clamping drivers 813 are each connected to a transfer clamp 83. Correspondingly, the pick-and-place mechanism 82 includes an X-axis module 821 mounted on the upper end of the bracket 84, a Z-axis module 822 connected to the output end of the X-axis module 821, and two clamping drivers 823 connected to the output end of the Z-axis module 822. The output ends of the two clamping drivers 823 are each connected to a transfer clamp 83. Among them, the four clamps 83 in the two pick-and-place mechanisms are arranged in a straight line along the X-axis direction, so that under the drive of the corresponding X-axis module 811 and the X-axis module 821, the four clamps 83 can be translated synchronously.

[0037] It should be noted that, in a preferred embodiment, the number of Z-axis modules 812 in the pick-and-place mechanism 81 is 2, and the corresponding two clamps 83 can alternately clamp the capacitors 200 after the shearing feet from the shearing foot device 50, and can synchronously place the two capacitors 200 at the bending device 60; and for the pick-and-place mechanism 82, only one Z-axis module 822 can be set, and the corresponding two clamps 83 can synchronously clamp and place the bent capacitors 200, thereby improving efficiency. It can be flexibly set according to actual needs, and effectively improve the adaptability of the transfer device 80.

[0038] See also Figure 7The bending device 60 includes a bending platform 61, a folding knife 62 arranged on the upper side end of the bending platform 61, and a bending driving mechanism 63 connected to the folding knife 62. A first slot 61a is provided at the connection between the top wall 611 and the side wall 612 of the bending platform 61, so that the two pins 201 of the capacitor 200 connected to the first slot 61a are suspended at the notch of the first slot 61a. The bending driving mechanism 63 can drive the folding knife 62 to approach the capacitor 200 and press its two pins 201 toward the side wall 612 to bend it. Specifically, in this embodiment, the folding knife 62 includes a left folding portion 621 and a right folding portion 622, and the left folding portion 621 and the right folding portion 622 can make a linear movement close to or away from each other, so that they can be inserted between the two pins 201 of the capacitor 200, and the two pins 201 can be bent in two opposite directions until the two pins 201 are bent to fit with the side wall 612, so as to form a 90° bent foot. The left folding portion 621 and the right folding portion 622 are specifically hook-shaped. Of course, in other embodiments, the folding knife 62 can also be an integral body and in a plate shape, so that the pins 201 can also be bent from top to bottom or from bottom to top.

[0039] In order to further improve the accuracy of bending, in a preferred embodiment of the present application, the bending device 60 also includes a downloading platform 64 arranged below the folding knife 62. The downloading platform 64 can support the pin 201 from below the pin 201 at the notch of the first card slot 61a, so that it can cooperate with the folding knife 62 to confine the pin 201 between the folding knife 62 and the downloading platform 64. When the left folding portion 621 and the right folding portion 622 move back to back to bend the pin 201, the two pins 201 are bent to both sides relative to the capacitor 200 body in the direction defined by the folding knife 62, the downloading platform 64 and the side wall 612, thereby making the bending more accurate.

[0040] Specifically, the driving mechanism 63 includes a Y-axis driving cylinder 631, a Z-axis driving cylinder 632 and a Z-axis driving cylinder 633 connected to the output end of the Y-axis driving cylinder 631, a downloading platform 64 connected to the output end of the Z-axis driving cylinder 632, a clamping cylinder 634 connected to the output end of the Z-axis driving cylinder 633, and a folding knife 62 connected to the output end of the clamping cylinder 634. The Y-axis driving cylinder 631 first drives the folding knife 62 and the downloading platform 64 to move linearly along the Y-axis direction, so that the folding knife 62 moves to be located directly above the pin 201, and the downloading platform 64 is transferred to abut against the side wall 612 of the bending platform 61. Afterwards, the Z-axis driving cylinder 632 and the Z-axis driving cylinder 633 are actuated to correspondingly drive the downloading platform 64 and the folding knife 62 to move linearly along the Z-axis, so that the downloading platform 64 moves up to be close to the first slot 61a to support the pin 201 from below, and the folding knife 62 also moves down to abut against the downloading platform 64, and the left folding part 621 and the right folding part 622 of the folding knife 62 are just inserted between the two pins 201, and the clamping cylinder 634 then drives the left folding part 621 and the right folding part 622 to move linearly away from each other, thereby bending the two pins 201.

[0041] Preferably, in order to improve efficiency, the bending device 60 can bend the pins 201 of two capacitors 200 at a time, and two first slots 61a are provided on the bending table 61, and the number of corresponding folding knives 62 is also two. The two folding knives 62 can be driven by the correspondingly connected clamping cylinders 634 to complete the bending of the pins 201 of the two capacitors 200. In order to optimize the structure, the two folding knives 62 can be connected to the output end of the same clamping cylinder 634, and the two folding knives 62 can be arranged in a staggered manner. At this time, the left folding portion 621 and the right folding portion 622 of each folding knife 62 are spaced a certain distance apart and are a whole. The left folding portion 621 and the right folding portion 622 of the same folding knife 62 cannot move relative to each other. Instead, the two left folding portions 621 of the two folding knives 62 abut against each other and can cooperate to complete the bending of one capacitor 200, and the two right folding portions 622 of the two folding knives 62 abut against each other and can cooperate to complete the bending of another capacitor 200.

A second slot 71a is provided at the connection between the top wall and the side wall of the test bench 71. The capacitor 200 is clamped in the second slot 71a in a direction in which the bending portion of the pin 201 can abut against the side wall. The probe 73 can move linearly under the drive of the linear driver 74, so that it can abut against the bending portion of the pin 201 to complete the corresponding characteristic test. The rotary driver 72 can drive the test bench 71 to rotate, so that the tested capacitor 200 is in a position that is convenient for the assembly device 30 to take and deliver. Of course, in order to improve efficiency, the detection device 70 can complete the characteristic test of two capacitors 200 each time, and two second slots 71a are arranged at intervals on the test bench 71. In addition, in order to improve assembly accuracy, a plasma blower 75 is also provided at the detection device 70 for dust removal. The air nozzle 751 of the plasma blower 75 is disposed on the upper side of the test bench 71 .

After the dispensing device 20 dispenses glue on the mounting seat 300, the positioning fixture 400 is transferred toward the direction of the assembly device 30. At the same time, the shearing device 50 first shears the pins 201 of the two capacitors 200, and the transfer device 80 transfers the two capacitors 200 after the shearing to the bending device 60. The transfer device 80 is reset when it is operated for the first time. When the other two capacitors 200 are sheared, the transfer device 80 transfers the two capacitors 200 after the shearing to the bending device 60, and the synchronous The two capacitors 200 with bent pins 201 placed at the bending device 60 are transferred to the detection device 70. After that, the transfer device 80 is reset, and the two capacitors 200 after the pins are cut and the two capacitors 200 after bending can be transferred synchronously in the future. The capacitors 200 detected by the detection device 70 are transferred to the conveyor belt 11 by the assembly device 30 for assembly. After the assembly is completed, the mounting seat 300 with the capacitor 200 is transferred to the unloading device 40 at the output end of the conveyor belt 11. The unloading device 40 removes the mounting seat 300 with qualified capacitor assembly from the positioning fixture 400 and transfers it to the direction of the next device. The defective products are removed and transferred to the corresponding defective product conveyor belt 43 according to the type of defective products, and the empty positioning fixture 400 is recycled. The above operations are repeated continuously to complete the automated assembly line operation of assembling the capacitor 200 on the mounting seat 300.

[0047] Compared with the prior art, the dispensing device 20, the assembly device 30 and the unloading device 40 of the capacitor assembly machine 100 of the present invention are arranged in sequence along the conveying direction of the conveying device 10, the shearing device 50, the bending device 60, the detection device 70 and the transfer device 80 are arranged between the dispensing device 20 and the assembly device 30, and the transfer device 80 is arranged between the shearing device 50, the bending device 60 and the detection device 70, then the transfer device 80 can go back and forth between the three, so as to transfer the capacitor 200 after the shearing at the shearing device 50 to the bending device 60, and can transfer the bending device 60 to the capacitor 200. The capacitor 200 after bending at 60 is transferred to the detection device 70 to complete the corresponding action. At the same time, the dispensing device 20 on the conveying device 10 can dispense glue to the assembly position 301 of the mounting seat 300. When the mounting seat 300 after dispensing glue is transferred to the assembly device 30, the assembly device 30 just aligns the capacitor 200 detected by the detection device 70 and assembles it on the mounting seat 300. When the mounting seat 300 after the capacitor is assembled is transferred to the unloading device 40, the unloading device 40 performs diversion and unloading according to whether the assembly is qualified, thereby completing the required assembly operation. The machine has a compact structure, high assembly accuracy and high degree of automation, which effectively reduces the setting of assembly equipment, omits manual transportation, and reduces manufacturing costs.
