Description

Technical Field

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

[0002] Capacitor production includes multiple processes, such as winding, gold spraying, heat setting, assembly, etc. The gold spraying process is usually: Figure 3 The automatic gold spraying machine 7 shown in the figure is provided with a conveying device for conveying Figure 4 The material frame 8 shown in the figure has a plurality of hanging rings 81 at one end. When the material frame 8 is conveyed, the conveying hook 73 of the conveying device hangs the hanging ring 81, moves and turns inside the automatic gold spraying machine 7, so that both ends of each core 9 are sprayed with gold. After the gold spraying is completed, the material frame 8 will move to the window 71 position of the automatic gold spraying machine 7. According to the specific model of the automatic gold spraying machine 7, the window plate 72 is opened manually or automatically, and the material frame 8 can be taken out. The arrangement of the cores 9 in the material frame 8 is usually as follows Figure 4 As shown, when the material frame 8 is in a vertical state, the cores 9 in its storage slots are arranged in multiple rows and staggered, and each horizontal row at the same height includes n cores 9.

[0003] At present, the automation level of capacitors during gold spraying is relatively high, but after gold spraying, the process of removing the material frame 8 and taking the core 9 out of the material frame 8 is relatively low in automation level and needs to be completed by manual operation. First, the worker needs to remove the material frame 8 from the conveying hook 73, and then place the material frame 8 on a horizontal plane, such as on the edge of a table, and then manually slap the core 9 into a pre-placed collection frame. In addition, the core 9 is already tightly packed in the material frame 8 before gold spraying, and it is difficult to move. After gold spraying, the metal solids attached between the core 9 and the inner wall of the material frame 8 will further make the core 9 fixed more tightly, so it is necessary to slap the core 9 with force. In addition, since gold is only sprayed on the end of the core 9, it is necessary to cover the outer peripheral side with protective paper to avoid short circuit or other electrical failures. The core 9 is randomly scattered in the collection frame. Before using it in the subsequent process, it is necessary to take it out one by one and manually tear off the protective paper. Sometimes, in order to facilitate the subsequent process, the core 9 that has been torn off the protective paper should be arranged neatly. Therefore, the entire capacitor core cutting process consumes a lot of manpower and has low efficiency. Summary of the invention

[0004] In view of the above-mentioned defects, the present invention provides a capacitor core unloading device, which can automatically complete the tasks of obtaining a material frame, unloading cores, and collecting cores, thereby saving manpower and improving unloading efficiency.

By automatically controlling the paper cutter to cut the protective paper, the cutting force can be controlled more accurately to avoid damage to the core caused by improper operation during manual cutting.

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.

[0038] like Figure 1~Figure 3 , Fig. 9 , Fig.16 , Fig.17As shown, the paper transfer unit 5 passes through both sides of the collecting unit 1 and is used to separate the protective paper on the core 9 in the storage rack 452. The paper transfer unit 5 includes a pair of twelfth linear mechanisms 51 respectively arranged on both sides of the unloading platform 11. A third rotating motor 52 is arranged on the sliding end of the twelfth linear mechanism 51, and a rotating rod 53 passing through the first side groove 15 is arranged at one end of the output shaft thereof. The outer peripheral side of the rotating rod 53 is fixed with n friction conveying wheels 54. After the protective paper of the core 9 is cut, as shown in FIG.

A rotating seat 55 is provided on the sliding end of another twelfth linear mechanism 51, and one end of the rotating rod 53 is rotatably matched with the rotating seat 55.

[0039] like Figure 1~Figure 3 , Fig. 9 , Fig.15 , Fig.17 As shown, the temporary storage unit 6 is arranged at one end of the collecting 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, one side of which is provided with an L-shaped horizontal frame 611, and one end of the long side of the L-shaped horizontal frame 611 is fixed to the side of the unloading platform 11. The output end of the thirteenth linear mechanism 61 is provided with a mounting seat 62, and one end of the mounting seat 62 is equipped with a temporary storage bucket 64. The lower end of the temporary storage bucket 64 is formed with an inclined portion 641, so that the protective paper can naturally fall into the temporary storage bucket 64. One end of the temporary storage bucket 64 is open, and The upper part of the opening end of the temporary storage bucket is respectively provided with n grooves 66 for the friction conveying wheel 54 to pass through. The inner bottom wall of the opening end of the temporary storage bucket is higher than the bottom end of the core 9 in a horizontal state, so that when the friction conveying wheel 54 conveys the protective paper into the temporary storage bucket 64, the core 9 is blocked and will not move. Specifically, a slot 63 is provided at the upper end of the mounting seat 62, and an inverted L-shaped plug block 65 is provided at the other end of the temporary storage bucket 64. When the vertical part of the inverted L-shaped plug block 65 is inserted into the slot 63, the temporary storage bucket 64 is fixedly connected to the output end of the thirteenth linear mechanism 61.

[0040] In this embodiment, the first linear mechanism 18, the second linear mechanism 21, the third linear mechanism 23, the fourth linear mechanism 26, the fifth linear mechanism 31, the seventh linear mechanism 34, the ninth linear mechanism 45, the tenth linear mechanism 46, the eleventh linear mechanism 462, and the thirteenth linear mechanism 61 all use linear hydraulic cylinders, and the sixth linear mechanism 32, the eighth linear mechanism 41, and the twelfth linear mechanism 51 all use rodless linear cylinders.

[0041] Working method: First, the material frame 8 is obtained by the material taking unit 2 and placed on the collecting unit 1, as follows: When the automatic gold spraying machine 7 finishes spraying a batch of cores 9 and opens the window plate 72, the second linear mechanism 21 and the connecting plate 22 move the positions of the bottom clamping assemblies, and then the bottom end of the material frame 8 is clamped by the bottom clamping assembly, and then the material frame 8 is moved upward first and then to the outside of the automatic gold spraying machine 7, so that the hanging ring 81 is separated from the conveying hook 73; Next, the material frame 8 is moved to the top of the unloading platform 11, and then the material frame 8 is rotated by the first rotating motor 24 so that the end of the lifting ring 81 first falls to the upper end surface 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 sets of side limit rods 17. At this time, the storage slot of the material frame 8 may not be exactly aligned with the square opening 13, then the first linear mechanism 18 controls the push plate 19 to make one end of the material frame 8 hit the end limit rod 171, so that the storage slot and the square opening 13 are aligned.

[0042] Then, the baffle 42 is moved by 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, while the other cores 9 are blocked by the baffle 42, and the position of the storage rack 452 is adjusted by the ninth linear mechanism 45, so that each storage position of the storage rack 452 is just below the above-mentioned n cores 9, and 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 the original position; After the core 9 is in the storage rack 452, the tenth linear mechanism 46 and the eleventh linear mechanism 462 control the paper cutters 47 to cut the protective paper from top to bottom. However, since the cores 9 are closely attached to each other and are limited by the end block, the first limit block 453 and the second limit block 454, the protective paper will not fall directly. Next, the position of the material storage rack 452 is adjusted by the ninth linear mechanism 45, and then the second rotary motor 44 is rotated to make the material storage rack 452 horizontal, and then the friction conveying wheels 54 are moved by the twelfth linear mechanisms 51, and then the temporary storage bucket 64 is pushed by the temporary storage unit 6, so that the material distribution unit, the paper transfer unit, and the temporary storage unit are partially in the following positions: Fig.17 The state shown, then the third rotary motor 52 is started to make the friction conveying wheel 54 convey the protection paper into the temporary storage bucket 64. During the conveying process, the friction conveying wheel 54 can also be slowly moved toward the groove 66 by the twelfth linear mechanism 51, so as to fully convey the protection paper into the temporary storage bucket 64. Then, the second rotary motor 44 is further rotated to align the end opening of the storage rack 452 with the opening of the arc-shaped slideway 48 at the top, as shown in FIG. Fig.18 As shown, the core 9 falls onto each conveyor belt conveyor 121 through the arc slide 48 and is transmitted to the subsequent process for use.

[0043] By analogy, the material storage rack 452 is flipped upward to be vertical again, and then the baffle plate 42 and the pressing plate 35 are moved to discharge the other cores 9 respectively.

[0044] After the cores 9 of a material frame 8 have been unloaded, the staff can take away the material frame 8 for standby use.

[0045] After multiple unloadings, the temporary storage bucket 64 will be filled with more protective paper, and the temporary storage bucket 64 can be moved out by the thirteenth linear mechanism 61, and then removed to pour out the protective paper.

[0046] The above are only some of the embodiments listed in this application and are not intended to limit this application.
