Description

Technical Field

[0001] The utility model relates to the technical field of resistor production, in particular to a high-speed taping machine for chip resistors. Background Art

[0002] The taping machine puts bulk component products into carrier tape. During the production process of existing chip resistors, the chip resistors need to be placed in a vibration plate, and the vibration plate is used to transport the chip resistors to the taping machine. The taping machine puts the chip resistors into the carrier tape. During the operation of the taping machine, it is usually necessary to cut them to the appropriate size.

[0003] In this regard, China applied for patent number: CN201921476485.6, which discloses a cutting device of a braiding machine, including a bottom plate, a support rod is fixedly installed on the top of the bottom plate, a fixed plate is welded on the top of the support rod, the fixed plate is a cavity structure, and a through strip through hole is opened on the upper and lower parts of the bottom plate, a cutting knife is arranged in the strip through hole of the fixed plate, a pressing seat is welded on the top of the fixed plate, and the material of the cutting knife is metal material, a support seat is welded on the top of the fixed plate, and a cylinder is arranged on the top of the support seat, the piston rod of the cylinder points to the pressing seat, and an extrusion seat is fixedly installed on one end of the piston rod. The utility model firstly enables the cutting knife to cut the produced cover tape and carrier tape more conveniently through the arrangement of the cylinder, the extrusion seat, the pressing seat and the spring; through the arrangement of the motor, the rotating fan blade and the heating resistor wire, the cutting knife can be heated during the cutting process, so as to heat-seal the cut surface.

[0004] The shearing device can heat the cutting knife by heating the resistance wire so as to heat-seal the cut surface. However, since the carrier tape is mostly made of PC material, the cut surface of the carrier tape will stick to the cutting knife when cut by the high-temperature cutting knife. As the cutting knife rises and resets, the carrier tape will be displaced, which will affect the subsequent use of the device.

[0005] Therefore, in order to solve the above problems, a high-speed taping machine for chip resistors is proposed. Utility Model Content

[0006] The purpose of the utility model is to provide a high-speed taping machine for chip resistors, so as to solve the problem that the shearing device in the prior art mentioned in the above background technology can heat the cutting knife by heating the resistance wire so as to heat-seal the cut surface, but since the carrier tape is mostly made of PC material, when it is cut by the high-temperature cutting knife, the cut surface of the carrier tape will stick to the cutting knife, and as the cutting knife rises and resets, the carrier tape will be displaced, which will affect the subsequent use of the device.

[0007] To achieve the above object, the utility model provides the following technical solution: a high-speed taping machine for chip resistors, comprising: a bracket, a vibration plate, a feeding mechanism and a conveying platform are installed on the top surface of the bracket;

[0008] A cutting structure is installed on the top surface of the bracket, and the cutting structure includes a mounting frame, the mounting frame is fixedly installed on the top surface of the bracket, a resistance heating block is fixedly installed on the inner side of the mounting frame, an electric telescopic rod is fixedly installed on the top surface of the mounting frame, the extended end of the electric telescopic rod is fixedly connected with a cutting knife body, the top surface of the cutting knife body is threadedly connected with a guide column, the outer side of the guide column is sleeved with a movable frame, the top surface of the movable frame is fixedly connected with a first spring, two groups of scrapers are slidably installed on the inner side wall of the movable frame, the surface of the scraper is fixedly connected with a second spring, the bottom surface of the scraper is fixedly installed with a fixed column, a movable column is movably installed inside the bottom end of the fixed column, the top surface of the movable column is fixedly connected with a third spring, and a rubber roller is movably installed on the bottom end of the movable column through a bearing.

[0009] Preferably, the vibration plate, the feeding mechanism and the mounting frame are arranged in sequence from right to left, and the conveying platform passes through the feeding mechanism and the mounting frame.

[0010] Preferably, the cutting knife body is located on the inner side of the resistance heating block, the first spring is sleeved on the outer side of the guide column, and one end of the first spring is fixedly connected to the guide column.

[0011] Preferably, the movable frame is in a "door"-shaped structure, and the movable frame is sleeved on the outer side of the cutting knife body.

[0012] Preferably, the two groups of scrapers are in contact with each other, the two groups of scrapers are located directly below the cutting knife body, and one end of the second spring is fixedly connected to the inner wall of the movable frame.

[0013] Preferably, one end of the third spring is fixedly connected to the inner wall of the fixing column.

[0014] Compared with the prior art, the beneficial effect of the utility model is as follows: the utility model arranges a rubber roller on the lower side of the cutting knife body, which can be pressed on both sides of the carrier tape cutting position, and can position the carrier tape after cutting, so that when the cutting knife body is raised and reset, the carrier tape can be located at the original position on the top surface of the conveyor platform, which can ensure the normal conveying of the carrier tape on the conveyor platform and facilitate subsequent processing and production.

[0015] The utility model is provided with a cutting structure, and the electric telescopic rod is started to drive the cutting knife body, the movable frame, the scraper and the rubber roller to descend. The rubber roller contacts the top surface of the carrier belt, and the electric telescopic rod cannot drive the rubber roller to continue to descend. Therefore, the continued action of the electric telescopic rod will cause the upper end of the movable column to retract into the fixed column and squeeze the third spring to make the cutting knife body and the scraper continue to descend. When the movable column moves into place in the fixed column, the scraper cannot continue to move downward. Therefore, when the electric telescopic rod drives the cutting knife body to continue to descend, the movable frame will move upward on the outer side of the guide column and squeeze the first spring to make the cutting knife body descend relative to the scraper. The cutting knife body will separate the two groups of scrapers to the left and right, so that the two groups of scrapers move inside the movable frame and By squeezing the second spring, the cutting knife body descends between the two groups of rubber rollers, and the part of the carrier belt between the two groups of rubber rollers can be cut off. When the electric telescopic rod drives the cutting knife body to rise and reset, the movable frame and the rubber roller will remain fixed under the action of the first spring. Therefore, the cutting knife body will rise between the two groups of rubber rollers, and the carrier belt will always be positioned on the top surface of the conveyor platform under the action of the rubber rollers, which can facilitate the separation of the cutting knife body and the carrier belt and avoid the carrier belt from sticking to the cutting knife body. As the cutting knife body rises, the cutting knife body will rise between the two groups of scrapers. The scrapers will fit closely to the surface of the cutting knife body under the action of the second spring, and can scrape off the debris on the surface of the cutting knife body, so as to keep the surface of the cutting knife body clean.

[0025] A high-speed tape-making machine for chip resistors, comprising: a bracket 1, a vibration plate 11, a feeding mechanism 12 and a conveying platform 13 are installed on the top surface of the bracket 1;

[0026] A cutting structure 2 is installed on the top surface of the bracket 1. The cutting structure 2 includes a mounting frame 21, which is fixedly mounted on the top surface of the bracket 1. A resistance heating block 22 is fixedly mounted on the inner side of the mounting frame 21. An electric telescopic rod 23 is fixedly mounted on the top surface of the mounting frame 21. The extended end of the electric telescopic rod 23 is fixedly connected to a cutting knife body 24. A guide column 25 is threadedly connected to the top surface of the cutting knife body 24. A movable frame 26 is sleeved on the outer side of the guide column 25. A first spring 27 is fixedly connected to the top surface of the movable frame 26. Two sets of scrapers 28 are slidably mounted on the inner side wall of the movable frame 26. The surface of the scraper 28 is fixedly connected to a second Spring 29, the bottom surface of the scraper 28 is fixedly installed with a fixed column 210, the bottom end of the fixed column 210 is movably installed with a movable column 211, the top surface of the movable column 211 is fixedly connected with a third spring 212, and the bottom end of the movable column 211 is movably installed with a rubber roller 213 through a bearing. By arranging the rubber roller 213 on the lower side of the cutting knife body 24, it can be pressed on both sides of the carrier tape cutting position, so that the carrier tape after cutting can be positioned, so that when the cutting knife body 24 is raised and reset, the carrier tape can be located at the original position on the top surface of the conveying platform 13, which can ensure the normal conveying of the carrier tape on the conveying platform 13 and facilitate subsequent processing and production.

[0027] Furthermore, the vibration plate 11 , the feeding mechanism 12 and the mounting frame 21 are arranged in sequence from right to left, and the conveying platform 13 runs through the feeding mechanism 12 and the mounting frame 21 , and the carrier tape can be conveyed to the left through the conveying platform 13 .

[0028] Furthermore, the cutting knife body 24 is located on the inner side of the resistance heating block 22, and the first spring 27 is sleeved on the outer side of the guide column 25. One end of the first spring 27 is fixedly connected to the guide column 25. The cutting knife body 24 can be heated by the resistance heating block 22. The first spring 27 provides power for the movable frame 26 to reset on the cutting knife body 24, so that when the cutting knife body 24 is reset upward, the rubber roller 213 can be fixed in place.

[0029] Furthermore, the movable frame 26 is in a “door”-shaped structure, and the movable frame 26 is sleeved on the outer side of the cutting knife body 24 . The movable frame 26 provides a position for installing the scraper 28 and the rubber roller 213 on the cutting knife body 24 .

[0030] Furthermore, the two groups of scrapers 28 fit together, and the two groups of scrapers 28 are located directly below the cutting knife body 24. One end of the second spring 29 is fixedly connected to the inner wall of the movable frame 26.

[0031] Furthermore, one end of the third spring 212 is fixedly connected to the inner wall of the fixed column 210 , and the third spring 212 provides power for resetting the movable column 211 in the fixed column 210 .

[0032] Working principle: When in use, the carrier belt moves from right to left on the top surface of the conveyor platform 13, the resistance heating block 22 is started, the cutting knife body 24 can be heated, the electric telescopic rod 23 is started, the cutting knife body 24, the movable frame 26, the scraper 28 and the rubber roller 213 can be driven to descend, and the rubber roller 213 contacts the top surface of the carrier belt, and the electric telescopic rod 23 cannot drive the rubber roller 213 to continue to descend, so the continued movement of the electric telescopic rod 23 will cause the upper end of the movable column 211 to retract into the fixed column 210, and squeeze the third spring 212, so that the cutting knife body 24 and the scraper 28 continue to descend;

[0033] When the movable column 211 moves into position in the fixed column 210, the scraper 28 cannot move further downward, so when the electric telescopic rod 23 drives the cutting knife body 24 to continue to descend, the movable frame 26 moves upward outside the guide column 25 and squeezes the first spring 27, so that the cutting knife body 24 descends relative to the scraper 28. The cutting knife body 24 separates the two groups of scrapers 28 to the left and right, so that the two groups of scrapers 28 move inside the movable frame 26 and squeeze the second spring 29. The cutting knife body 24 descends between the two groups of rubber rollers 213, and the portion of the carrier tape located between the two groups of rubber rollers 213 can be cut off;

[0034] When the electric telescopic rod 23 drives the cutting knife body 24 to rise and reset, the movable frame 26 and the rubber roller 213 will remain fixed under the action of the first spring 27, so the cutting knife body 24 will rise between the two groups of rubber rollers 213, and the carrier belt will always be positioned on the top surface of the conveyor platform 13 under the action of the rubber roller 213, which can facilitate the separation of the cutting knife body 24 and the carrier belt, and avoid the carrier belt from sticking to the cutting knife body 24. As the cutting knife body 24 rises, the cutting knife body 24 will rise between the two groups of scrapers 28. The scrapers 28 are tightly attached to the surface of the cutting knife body 24 under the action of the second spring 29, and can scrape off the debris on the surface of the cutting knife body 24, so as to keep the surface of the cutting knife body 24 clean.
