Description

Technical Field

[0001] The present invention relates to the technical field of capacitor production equipment, and particularly relates to a capacitor core blanking device. Background Art

[0002] The production of capacitors includes multiple processes, such as winding, spraying gold, heat setting, assembly, etc. The gold spraying process usually involves using an automatic gold spraying machine 7 as shown in Figure 3 wherein there is a conveying device for conveying a material frame 8 as shown in Figure 4 One end of the material frame 8 is provided with a plurality of hanging rings 81. When conveying the material frame 8, the conveying hook 73 of the conveying device hangs the hanging rings 81, moves and flips inside the automatic gold spraying machine 7, so that both ends of each core 9 are completed with gold spraying. After the gold spraying is completed, the material frame 8 will move to the position of the window 71 of the automatic gold spraying machine 7. According to the specific model of the automatic gold spraying machine 7, the window plate 72 is manually or automatically opened, and then the material frame 8 can be taken out. For the arrangement of the cores 9 in the material frame 8, it is usually as shown in Figure 4 When the material frame 8 is in a vertical state, the cores 9 in its storage groove are arranged in multiple staggered columns, and each horizontal row at the same height includes n cores 9.

[0003] At present, the degree of automation in gold spraying capacitors is relatively high. However, after the gold spraying is completed, the degree of automation in removing the material frame 8 and taking out the cores 9 from the material frame 8 is relatively low and needs to be completed manually. First, the worker needs to remove the material frame 8 from the conveying hook 73, then place the material frame 8 on a horizontal surface, such as the edge of a table, and then manually pat the cores 9 into a pre-placed collection box. Moreover, the cores 9 were already tightly packed in the material frame 8 before gold spraying and were difficult to move. After gold spraying, the metal solids attached between the cores 9 and between the cores 9 and the inner wall of the material frame 8 will further make the cores 9 fixed more tightly, so it is necessary to pat the cores 9 forcefully. In addition, since only the ends of the cores 9 are sprayed with gold, it is necessary to cover the outer peripheral side with protective paper to avoid short circuits or other electrical faults. The cores 9 are randomly scattered in the collection box. Before being used in subsequent processes, it is also necessary to take them out one by one and manually tear off the protective paper. Sometimes, in order to facilitate the subsequent processes, the cores 9 with the protective paper torn off also need to be arranged neatly. Therefore, the entire capacitor core blanking process consumes a lot of manpower and has low efficiency. Summary of the Invention

[0004] In view of the above defects, the present invention provides a capacitor core blanking device, which can automatically complete the work of obtaining the material frame, core blanking, and core collection, can save manpower, and improve the blanking efficiency.

[0005] In order to achieve the purpose of the present invention, the following technologies are proposed:

[0006] A capacitor core blanking device, comprising:

[0007] A collection unit, disposed outside the window of an automatic gold spraying machine, includes a discharging table, one end of which is provided with a discharging port. On the inner bottom surface of the discharging table, there are n conveyor belt conveyors extending outside the discharging port. A square opening is provided at the upper end of the discharging table, and a positioning assembly for positioning the material frame is further provided on the upper end surface of the discharging table;

[0008] A material taking unit, disposed on one side of the collection unit, is used to take down a material frame that has completed the gold spraying of the core in the automatic gold spraying machine and transfer it to the discharging table;

[0009] A material pressing unit, disposed on the other side of the collection unit, is used to press the cores in the material frame on the discharging table into the discharging table row by row;

[0010] A material distributing unit, passing through one side of the discharging table, includes an eighth linear mechanism fixed to one side surface of the discharging table. On one side of the sliding end of the eighth linear mechanism, there is a baffle plate located inside the discharging table. On one side of the lower end of the baffle plate, there are a second rotating motor and an arc-shaped slideway. One end of the output shaft of the second rotating motor is provided with a ninth linear mechanism. The output end of the ninth linear mechanism is provided with a storage rack and a tenth linear mechanism. The storage rack is used to temporarily store n cores. The output end of the tenth linear mechanism is provided with an eleventh linear mechanism.

The bottom end surface and the upper inclined surface of the arc-shaped slideway are both open, and there are n - 1 material distributing plates arranged inside the arc-shaped slideway;

[0011] A paper transfer unit, passing through both sides of the collection unit, is used to separate the protective paper on the cores in the storage rack;

[0012] A temporary storage unit, disposed at one end of the collection unit, is used to temporarily store the protective paper separated by the paper transfer unit.

[0013] Further, the positioning assembly includes two groups of side limiting rods respectively disposed on both sides above the square opening, and a number of end limiting rods. The end limiting rods are disposed at one end above the square opening, and a first linear mechanism is disposed at the other end above the square opening. The output end of the first linear mechanism is provided with a push plate.

[0014] Further, the material taking unit includes a second linear mechanism with an output end pointing to the automatic gold spraying machine. On one side of the output end of the second linear mechanism, a third linear mechanism is vertically provided. At the upper end of the output shaft of the third linear mechanism, there is a first rotating motor. On one side of one end of the output shaft of the first rotating motor, there is an end plate. On one side surface of the end plate, there are a number of bottom clamping assemblies for clamping the material frame in the window from the bottom.

[0015] Further, the material pressing unit includes a fifth linear mechanism, the output end of which is provided with a sixth linear mechanism.

[0018] The beneficial effects of this technical solution are as follows:

[0019] 1. Through the material taking unit, the material frame can be automatically removed and placed on the collection unit. Through the material pressing unit and the material distributing unit, the cores in the material frame can be automatically distributed to each conveyor belt conveyor. Moreover, the unloaded cores are not randomly stacked, but are placed on the conveyor belt conveyor in sequence, group by group, each time, which is convenient for the subsequent production processes and can improve the automation level and the unloading efficiency of the capacitor cores.

[0020] 2. During the process of unloading the cores, the protective paper is automatically removed and collected, achieving the effect of eliminating the need for manual removal of the protective paper. By automatically controlling the cutting knife to cut the protective paper, the cutting force can be more accurately controlled, avoiding damage to the cores caused by improper operation during manual cutting.

[0045] As Figures 1 to 3 , Figures 9 to 14 , Figure 17 , Figure 18As shown, the material dividing unit 4 is arranged on one side of the unloading platform 11, including an eighth linear mechanism 41 fixed to one side of the unloading platform 11, a vertical block 411 is arranged on the upper end of the sliding end, a side plate 412 which is slidably matched with the second side groove 16 is arranged on the upper end of the vertical block 411, and a baffle 42 is arranged at one end of the side plate 412. When the sliding end of the eighth linear mechanism 41 moves to a predetermined position in a direction close to the automatic gold spraying machine 7, part of the baffle 42 passes through the end groove 14 to block the core 9 in the material frame 8 from being temporarily pressed into the unloading platform 11.

There are n-1 first limit blocks 453 and n-1 second limit blocks 454, and both sides of one end of the first limit block 453 and both sides of one end of the second limit block 454 are also respectively provided with arc surfaces matching the outer circumference of the core 9, and a first limit block 453 and a second limit block 454 are provided between each adjacent two cores 9. A tenth straight-line mechanism 46 is provided on one side of the support plate 451, and a convex plate 461 is provided at its output end. An eleventh straight-line mechanism 462 is provided at one end of the convex plate 461, and its output direction is parallel to the axial direction of the core 9 placed in the storage rack 452. The eleventh straight-line mechanism 462 outputs A frame plate 463 is provided at the end, and n paper cutters 47 for cutting the protective paper covering the outer surface of the core 9 are provided on one side of the frame plate 463. An arc-shaped slide 48 is provided at one end of the horizontal part of the L-shaped hanging plate 43, and its bottom end surface is parallel to the horizontal plane. The bottom end surface and the inclined surface of the upper end of the arc-shaped slide 48 are both open, and the opening at the top is smaller than the opening at the bottom. n-1 dividing plates 49 for spacing the cores 9 are provided in the arc-shaped slide 48, and the width of the dividing plates 49 increases successively from top to bottom. When the n cores 9 are separated from the arc-shaped slide 48 from the opening at the bottom end of the arc-shaped slide 48, they fall onto each conveyor belt conveyor 121 respectively.

[0046] like Figures 1 to 3 , Figure 9 , Figure 16 , Figure 17As shown, the paper transfer unit 5 penetrates both sides of the collection unit 1 and is used to separate the protective paper on the core 9 in the stock rack 452. The paper transfer unit 5 includes a pair of twelfth linear mechanisms 51 respectively arranged on both sides of the unloading table 11. A third rotary motor 52 is provided on the sliding end of one twelfth linear mechanism 51. One end of its output shaft is provided with a rotating rod 53 passing through the first side groove 15. n friction conveying wheels 54 are fixed on the outer peripheral side of the rotating rod 53. After the protective paper of the core 9 is cut, as Figure 17 shown, the friction conveying wheels 54 contact the outer peripheral side of the core 9 from the gap between adjacent first limit blocks 453 or between the first limit block 453 and the end block. A rotating seat 55 is provided on the sliding end of the other twelfth linear mechanism 51. One end of the rotating rod 53 is rotatably fitted to the rotating seat 55.

[0047] As Figures 1 to 3 , Figure 9 , Figure 15 , Figure 17 shown, the temporary storage unit 6 is arranged at one end of the collection unit 1 and is used to temporarily store the protective paper separated by the paper transfer unit 5. The temporary storage unit 6 includes a thirteenth linear mechanism 61. An L-shaped cross frame 611 is provided on one side of it. One long side end of the L-shaped cross frame 611 is fixed to the side of the unloading table 11. An installation seat 62 is provided at the output end of the thirteenth linear mechanism 61. A temporary storage hopper 64 is assembled at one end of the installation seat 62.

One end of the temporary storage hopper 64 is open, and n grooves 66 for the friction conveying wheels 54 to pass through are respectively opened in the upper part of the open end of the temporary storage hopper. The inner bottom wall of the open end of the temporary storage hopper is higher than the bottom end of the core 9 in the horizontal state, so that when the friction conveying wheels 54 convey the protective paper into the temporary storage hopper 64, the core 9 is blocked and will not move. Specifically, a slot 63 is opened at the upper end of the installation seat 62. A reverse L-shaped insertion block 65 is provided at the other end of the temporary storage hopper 64. When the vertical part of the reverse L-shaped insertion block 65 is inserted into the slot 63, the temporary storage hopper 64 is fixedly connected to the output end of the thirteenth linear mechanism 61.

[0049] Working mode:

[0050] First, the material box 8 is obtained by the material taking unit 2 and placed on the collection unit 1, specifically as follows:

[0051] After the automatic gold spraying machine 7 finishes gold spraying a batch of cores 9 and opens the window plate 72, the positions of each bottom clamp assembly are moved through the second linear mechanism 21 and the connecting plate 22, and then the bottom end of the material frame 8 is clamped by the bottom clamp assembly. Then, the material frame 8 is first moved upward and then moved outward to the side of the automatic gold spraying machine 7 to disengage the hanging ring 81 from the conveying hook 73;

[0052] Next, the material frame 8 is moved above the unloading platform 11, and then the material frame 8 is rotated by the first rotating motor 24 so that the end of the hanging ring 81 first falls onto the upper end face of the unloading platform 11, and then the material frame 8 is slowly lowered and released so that it is located on the unloading platform 11, and the material frame 8 is between the two groups of side limiting rods 17. At this time, the storage groove of the material frame 8 may not be exactly aligned with the square opening 13, so the first linear mechanism 18 is used to control the push plate 19 to push one end of the material frame 8 against the end limiting rod 171 to align the storage groove with the square opening 13.

[0053] Then, the baffle 42 is moved through the eighth linear mechanism 41 so that the n cores 9 closest to the first linear mechanism 18 can fall into the unloading platform 11, and the other cores 9 are blocked by the baffle 42. And the position of the storage rack 452 is adjusted through the ninth linear mechanism 45 so that each storage position of the storage rack 452 is exactly below the above-mentioned n cores 9. Then, the n cores 9 are pressed down by the pressing unit 3, and these cores 9 fall into the storage rack 452. And due to the blocking of the baffle 42 and the adhesion of the metal, the other cores 9 remain in their original positions;

[0054] After the cores 9 are in the storage rack 452, the tenth linear mechanism 46 and the eleventh linear mechanism 462 are used to control each paper cutter 47 to cut the protective paper from top to bottom. However, since the cores 9 are close to each other and are limited by the end blocks, the first limit block 453, and the second limit block 454, the protective paper will not fall directly;

[0055] Next, the position of the storage rack 452 is adjusted through the ninth linear mechanism 45, and then it is rotated by the second rotating motor 44 to make the storage rack 452 horizontal. Then, each friction conveying wheel 54 is moved through each twelfth linear mechanism 51, and then the temporary storage unit 6 is used to push the temporary storage hopper 64 so that the local parts of the material distribution unit, the paper transfer unit, and the temporary storage unit are in the state as shown in Figure 17 shown. Then, the third rotating motor 52 is started to make the friction conveying wheel 54 convey the protective paper into the temporary storage hopper 64. During the conveying process, the friction conveying wheel 54 can also be slowly moved toward the groove 66 through the twelfth linear mechanism 51 to facilitate fully feeding the protective paper into the temporary storage hopper 64;

[0056] Then, it is further rotated by the second rotating motor 44 to align the end opening of the storage rack 452 with the upper opening of the arc-shaped slideway 48, as shown in Figure 18As shown, the core 9 falls onto each conveyor belt conveyor 121 through the arc-shaped slideway 48 and is conveyed for use in subsequent processes.

[0057] And so on, the storage rack 452 is flipped upward again to the vertical position, and then the positions of the baffle 42 and the pressing plate 35 are adjusted to separately feed other cores 9.

[0058] After all the cores 9 in a material frame 8 are fed, the staff can take away the material frame 8 for standby.

[0059] After feeding multiple times, the temporary storage hopper 64 will contain more protective paper, which can be removed from the temporary storage hopper 64 through the thirteenth linear mechanism 61, and then taken off to pour out the protective paper.

[0060] The above are only some of the embodiments listed in this application and are not intended to limit this application.
