Description

Technical Field

[0001] This utility model relates to the field of electronic component manufacturing, and in particular to a paper tape folding device used in the production of ceramic capacitors and varistors. Background Technology

[0002] Ceramic capacitors and varistors are in the millimeter or even sub-millimeter size. Therefore, for ease of production and quality inspection, the leads of ceramic capacitors and varistors are neatly arranged and pasted onto paper tape. When packaging the products, the paper tape is folded to a certain length and then boxed.

[0003] The technical solution disclosed in Chinese utility model patent application number 201910638524.6, entitled "A Capacitor Lead Cutting and Packaging Machine," involves the tape being driven into the space between two guide blocks by friction between a flattening drive wheel and a rubber-coating wheel. A folding block is positioned on each side of the guide block's discharge end, and a folding cylinder is connected to the outer side of each folding block. When the tape passes between the two folding blocks, the two folding cylinders drive the two folding blocks to contract inward, thereby pressing creases into the tape. However, this technology still has the following technical problems in use:

[0004] First, the conveying of the tape is accomplished by the flattening drive wheel and the rubber-coated wheel, and the folding is accomplished by the folding block driven by the folding cylinder. In this way, the movement of the tape and the pressing out of the folds are accomplished by two different mechanisms, which makes the structure of the device relatively loose, occupies a large space, and has high manufacturing cost and low operating efficiency.

[0005] Furthermore, the movement of the tape is accomplished by the friction generated by the squeezing between the tape and the flattening drive pulley and the rubber-coated pulley. This will cause a certain degree of wear on the surface of the tape, affecting its quality. On the other hand, when electronic components are installed on the tape, the squeezing between the flattening drive pulley and the rubber-coated pulley will damage the electronic components. Therefore, this device is not suitable for tapes with electronic components, and its application range is relatively small.

[0006] Given the above-mentioned shortcomings of the existing technology, the applicant believes it is necessary to improve it to provide a paper tape crease structure that occupies less space, has lower operating costs, and is more widely applicable. Utility Model Content

[0007] The purpose of this invention is to solve the above-mentioned problems and shortcomings, and to provide a paper tape folding structure for the production of ceramic capacitors and varistors. This paper tape folding structure is provided with master and slave folding blocks, as well as pins and pin slots on the drive and slave disks, respectively, so that the paper tape transfer and folding can be realized in one mechanism. The overall structure is not only compact and occupies little space, but also has low manufacturing cost, high efficiency, and wider application range.

[0008] The technical solution of this utility model is implemented as follows: a paper tape crease structure applied to the production of ceramic capacitors and varistors includes an active disk, a driven disk, a main crease block, and a secondary crease block. The main crease block is mounted on the active disk, and the secondary crease block is mounted on the driven disk. The main crease cutting edge on the main crease block and the secondary crease cutting edge on the secondary crease block are arranged in opposite directions. A guide pin and a pin groove for moving the paper tape are also provided between the active disk and the driven disk.

[0009] Furthermore, the main crease blocks are installed on the driving disk in a cross-shaped, equally spaced manner, while the secondary crease blocks are installed on the driven disk in a straight, symmetrical manner.

[0010] Furthermore, the active disc has a plurality of equally spaced dial pins on its circumferential side surface, and the driven disc has annular pin grooves on its circumferential side surface.

[0011] Furthermore, the active disk has several insertion holes on its circumferential side for mounting the pins; the top surface of the active disk also has several screw holes that communicate with the insertion holes; and the top surface of the active disk located inside the screw holes also has adjustment holes that communicate with the insertion holes.

[0012] Furthermore, the top surface of the active disk is provided with a main mounting groove for mounting the main crease block; the main mounting groove is composed of a through-hole wide groove and a long groove, making the main mounting groove as a whole T-shaped structure; the main crease block is correspondingly composed of an integrally connected crease blade, a mounting part, and a connecting part connecting the crease blade and the mounting part, with the main crease blade located at the front end of the crease blade; the width of the mounting part is set to be greater than the width of the crease blade and the connecting part, making the main crease block as a whole T-shaped structure; the mounting part is embedded in the wide groove, and the connecting part and the crease blade are arranged along the long groove.

[0013] The beneficial effects of this utility model are as follows: This application installs the main crease block and the secondary crease block on the driving disc and the driven disc respectively, with the crease edges of the main and secondary crease blocks arranged in opposite directions. A guide pin and a groove are provided between the circumferential sides of the driving and driven discs. During operation, the driving and driven discs rotate relative to each other, using the cooperation of the guide pin and groove to move the paper tape by a prying motion. Simultaneously, when the main and secondary crease blocks collide, their crease edges interlock, squeezing creases onto the paper tape passing between them. This ensures that the paper tape is stably and automatically folded and arranged together when transported to the folding tray. This application integrates the paper tape transport and crease creation into a single mechanism, making the entire crease mechanism more compact, occupying less space, reducing manufacturing costs, and increasing operating efficiency. Furthermore, since the paper tape transfer in this application is accomplished through the cooperation of the pin and the pin groove, the active and driven discs will not cause direct wear, stretching, deformation, or breakage to the paper tape itself. They will only fold and indent the paper tape at intervals. Even if there are small electronic components installed on the paper tape, they will not be damaged. Therefore, its application scenarios are wider. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0021] like Figure 1As shown, a paper tape crease structure for use in the production of ceramic capacitors and varistors includes an active disk 1, a driven disk 2, a main crease block 3, and a secondary crease block 4. To achieve the purpose of this invention, the main crease block 3 is mounted on the active disk 1, and the secondary crease block 4 is mounted on the driven disk 2. The main crease cutting edge 31 on the main crease block 3 and the secondary crease cutting edge 41 on the secondary crease block 4 are arranged in opposite directions. A guide pin 5 and a pin groove 6 for moving the paper tape are also provided between the circumferential sides of the active disk 1 and the driven disk 2. During operation, the driving disc 1 and the driven disc 2 rotate in opposite directions, and the main crease block 3 and the secondary crease block 4 are squeezed together. The main crease cutting edge 31 and the secondary crease block 4 interlock, thereby pressing creases into the paper tape. The paper tape is propelled forward by inserting a needle 5 through a hole in the paper tape, and the needle 5 is embedded in the needle groove 6. The driving disc 1 and the driven disc 2 can rotate very smoothly, ensuring smooth and stable production. At the same time, the main crease block 3 and the secondary crease block 4 can be squeezed together very tightly, thus ensuring that creases are pressed into the paper tape. In this way, the driving disc 1 and the driven disc 2 can both move the paper tape and simultaneously crease it, making the structure of this utility model very compact, saving space, and effectively reducing the manufacturing cost of the equipment.

[0022] In this application, since the paper tape is transferred by actuating a pin 3 on the drive disk 1, the transfer distance of the paper tape per unit time can be controlled by adjusting the rotation speed of the drive disk 1. The creases on the paper tape are created by the compression between the main crease block 3 and the secondary crease block 4; therefore, the spacing of the creases on the paper tape can be adjusted by regulating the rotation speeds of the drive disk 1 and the driven disk 2. When the drive disk 1 rotates quickly and the driven disk 2 rotates slowly, the paper tape moves a longer distance per unit time, and the frequency of compression between the main crease block 3 and the secondary crease block 4 is low, resulting in a longer spacing of the creases on the paper tape. Figure 1 As shown, to flexibly adjust the distance between creases on the paper tape, multiple main crease blocks 3 can be set on the circumferential side of the drive disc 1. This allows for a shorter crease spacing on the paper tape when the drive disc 1 rotates at the same speed. Preferably, the main crease blocks 3 are installed on the drive disc 1 in a cross-shaped, equally spaced arrangement, allowing for equal adjustment of the crease spacing. To further increase adjustment flexibility, the secondary crease blocks 4 are also installed on the driven disc 2 in a symmetrical, linear arrangement. This ensures that for every rotation of the driven disc 2, the secondary crease blocks 4 have two opportunities to press against the main crease blocks 3. Thus, the crease spacing on the paper tape can be adjusted by changing the speed of either the drive disc 1 or the driven disc 2, providing greater operational flexibility and allowing for the creation of creases with various spacings on the paper tape, thereby meeting the needs of various paper tape packaging.

[0023] like Figure 1As shown, the active disk 1 has several equally spaced needles 5 arranged on its circumferential side surface. In actual production, the spacing between the needles 5 is set to be the same as the hole spacing on the paper tape to achieve stable and uniform speed feeding of the paper tape, thereby ensuring precise control of the crease spacing. The driven disk 2 has annular needle grooves 6 arranged on its circumferential side surface, so that the needles 5 will not be stuck when moving in the needle grooves 6, ensuring smooth rotation of the active disk 1 and the driven disk 2.

[0024] like Figure 4 , 5 As shown, to facilitate the installation of the pin 5 onto the drive plate 1, the drive plate 1 has several insertion holes 12 along its circumferential side for inserting the pin 5. To further enhance the stability of the pin 5, the top surface of the drive plate 1 also has several screw holes 13 that communicate with the insertion holes 12. During installation, the pin 5 is first inserted into the insertion hole 12, and then screwed into the screw hole 13 to tighten it. This also makes the replacement of the pin 5 very convenient; if the paper tape is thicker, the pin 5 needs to be slightly longer, and if the paper tape is thinner, the pin 5 needs to be slightly shorter. To further facilitate the adjustment of the pin 5's length, an adjustment hole 14 communicating with the insertion hole 12 is also provided on the top surface of the drive plate 1, located inside the screw hole 13. This allows for the selection of a longer pin 5, and the adjustment hole 14 can be used to adjust the length of the pin 5 extending out of the insertion hole 12 to match different thicknesses of paper tape. This allows for length adjustment without removing pin 5, greatly increasing operational flexibility.

[0025] like Figures 1 to 4 As shown, the top surface of the active disk 1 is provided with a main mounting groove 11 for mounting the main crease block 3; the main mounting groove 11 is composed of a through-hole wide groove 111 and a long groove 112, the wide groove 11 is arranged along the circumference of the active disk 1, and the long groove 112 is arranged along the radial direction of the active disk 1, so that the main mounting groove 11 has an overall T-shaped structure; the main crease block 3 is correspondingly composed of an integrally connected crease blade 30, a mounting part 32, and a connecting part 33 connecting the crease blade 30 and the mounting part 32, the main crease blade 31 is located at the front end of the crease blade 30; the width of the mounting part 32 is set to be greater than the width of the crease blade 30 and the connecting part 33, so that the main crease block 3 has an overall T-shaped structure; the mounting part 32 is embedded in the wide groove 111, and the connecting part 33 and the crease blade 30 are arranged along the long groove 112. Since both the main mounting groove 11 and the main crease block 3 are T-shaped structures, when the main crease block 3 is placed in the main mounting groove 11 during assembly, the main crease block 3 is not easy to fall out due to the limiting effect of the wide groove 111 on the mounting part 32, which prevents the crease edge 30 from being damaged by bumps and can also greatly speed up the assembly efficiency.

[0026] In actual production, paper tape comes in various specifications and thicknesses. To accommodate folding and creasing of paper tapes of different specifications, such as... Figure 1 , 2 As shown in Figure 3, the mounting part 32 has an elongated hole 321 that can be screwed into the wide slot 111 and moved back and forth. The crease blade 30 extends out of the outer edge of the drive disc 1 along the elongated slot 112. This allows adjustment of the length of the crease blade 30 extending out of the outer edge of the drive disc 1 to accommodate the crease requirements of paper tapes of different thicknesses, thereby greatly improving the applicability and operational flexibility of this utility model.

[0027] like Figure 2 , 3 As shown in Figure 4, the crease blade 30 is higher than the connecting part 33 and the mounting part 32, and the crease blade 30 is arranged with its bottom surface protruding from the bottom surface of the mounting part 32 and the connecting part 33; the front end of the elongated groove 112 is correspondingly provided with a clearance notch 113 for the crease blade 30 to be accommodated. In this way, the crease blade 30 can be made relatively large, thereby adapting to the processing of paper tapes of various widths.

[0028] Furthermore, the length of the clearance notch 113 is the same as the length of the crease blade 30, and the overall length of the main mounting groove 11 is equal to the overall length of the main crease block 3. This way, when a larger crease spacing is required on the paper tape and the number of main crease blocks 3 needs to be reduced, the main crease blocks 3 can simply be completely retracted into the main mounting groove 11 without needing to be removed, thus preventing the main crease blocks 3 from being lost due to improper storage.

[0029] like Figure 1 , 4 As shown in Figure 6, in order to save costs, the main crease block 3 and the secondary crease block 4 are crease blocks with the same structure. In this way, the same mold can be used for both during manufacturing, thereby saving production costs. Correspondingly, the structure of the secondary mounting groove 21 on the driven plate 2 that accommodates the secondary crease block 4 is also the same as the structure of the main mounting groove 11.

[0030] like Figure 1 , 2 As shown in Figure 3, a pressing protrusion 301 with an outer arc-shaped structure is provided on one side of the top of the crease blade 30, and a main crease edge 31 is formed between the other side of the top of the crease blade 30 and the pressing protrusion 301. In this way, when the main crease block 3 and the crease block 4 rotate and press in opposite directions, the rotation between the arc-shaped surfaces is relatively smooth and there will be no jamming, thus enabling production to proceed very smoothly.

[0031] like Figure 1As shown, bearing sleeve portions 15 are respectively provided at the center of the top surface of the driving disk 1 and the driven disk 2. The bearing sleeve portion 15 includes a fixed portion 151 and a movable portion 152. The two fixed portions 151 are respectively fixed to the top surface of the driving disk 1 and the driven disk 2. The movable portion 152 is screwed to the fixed portion 151 from the side. In this way, the movable portion 152 can be tightened from the top surface, so that the driving disk 1 or the driven disk 2 can be easily assembled onto the bearing. On the other hand, the movable portion 152 can also be loosened from the top surface to adjust the installation position of the driving disk 1 or the driven disk 2 on the bearing, so that the main crease block 3 and the secondary crease block 4 can be pressed together very precisely, thereby pressing out a stable crease on the paper tape.
