Description

Technical Field

[0001] The utility model belongs to the technical field of taping winding equipment for electronic components, and particularly relates to a multi-segment shearing mechanism with layered structure for a taping winder. Background Art

[0002] Small-sized electronic components such as capacitors, inductors, electronic wafers, crystal oscillator components, etc. are usually packaged or transferred by taping. Generally, the tape includes a base tape and a film. The base tape is provided with recesses for accommodating the electronic components, and then the packaging is achieved by hot-pressing and bonding the film. After continuous production of taping packaging, it is usually segmented and wound according to specifications, and wound by a taping winder.

[0003] In the existing taping winder, after the previous roll of tape is wound, the base tape and the film are directly cut, and then the next roll is wound. In this way, the ends of the base tape and the film of each roll of tape produced are flush and thermally bonded together, making it very difficult to separate the base tape and the film subsequently, which brings inconvenience to the use of electronic components and affects production efficiency.

[0004] Therefore, the applicant adjusted the winding and shearing process. When the base tape and the film of the tape are compounded, a blank section without components is reserved at a certain distance according to the winding specification, and the base tape and the film in this section are not thermally sealed and are in a separable state. During subsequent shearing, the blank section is segmented and sheared. Based on this, the present multi-segment shearing mechanism with layered structure is developed to apply to the above process. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a multi-segment shearing mechanism with layered structure for a taping winder, aiming to solve the technical problem that the ends of the tape are flush and difficult to peel off after winding in the existing technology.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A multi-segment shearing mechanism with layered structure for a taping winder, which includes a transmission track substrate arranged at an inclined angle between the winding guiding mechanism and the tape traction mechanism of the taping winder. The high-position end of the transmission track substrate has a tape inlet track opposite to the outlet end of the tape traction mechanism, and the low-position end of the transmission track substrate has a tape outlet track opposite to the inlet end of the winding guiding mechanism; between the tape inlet track and the tape outlet track on the transmission track substrate, there is a hollow connecting section that connects the two and penetrates the transmission track substrate up and down. At the starting end of the hollow connecting section, a swing block is installed. The swing block is provided with a movable track connected to the end of the tape inlet track. The swing block is driven by a swing driving cylinder and its output swing shaft installed on the lower surface of the transmission track substrate; the tape inlet track, the tape outlet track, and the movable track on the swing block are arranged along the same axial direction;

[0008] A first cover plate is installed on the upper part of the hollow connection section of the transmission track substrate. The first cover plate is provided with vacuum adsorption holes and is connected to a vacuum adsorption nozzle.

[0009] A shearing assembly is also installed on the lower surface of the transmission track substrate, on the side of the tail end of the hollow connection section. The shearing assembly includes a blade seat, a blade seat slide rail, a blade seat propulsion cylinder, and a shearing cylinder. The blade seat is provided with an upper blade and a lower blade, and the output end of the shearing cylinder drives the blade to move to achieve shearing.

[0010] Furthermore, the swing block is in a right-angled bent shape. The movable track is arranged on the outer corner surface of the swing block, and the starting end of the movable track on the swing block inclines downward; the output swing shaft of the swing driving cylinder is connected to the middle of the vertical side of the swing block; in this way, when the swing block rotates around the swing shaft towards the tail end direction, the starting end of the movable track will not lift the tape and cause tape jamming, which can ensure the continuous transmission of the tape. During normal transmission, the starting end of the movable track is located lower and does not affect the transmission of the tape;

[0011] Furthermore, the blade seat propulsion cylinder and the blade seat slide rail are fixedly arranged on the lower surface of the transmission track substrate. The blade seat is movably arranged on the blade seat slide rail and is connected to the output end of the blade seat propulsion cylinder. The blade seat propulsion cylinder can reciprocally drive the blade seat and the blade thereon to move to the shearing position. The upper blade is a fixed blade, which is arranged adjacent to the lower surface of the track substrate. The lower blade is a movable blade. The shearing cylinder is installed below the tail end of the hollow connection section through a second suspension plate, and its output end is arranged upward. When the blade on the blade seat moves to the shearing position, that is, when the upper and lower blades extend into the hollow connection section, the output end of the shearing cylinder jacks up upward to drive the lower blade upward to achieve a shearing action with the upper blade;

[0012] Furthermore, the starting end of the tape outlet track has a guiding inclined surface that inclines downward, which is convenient for the cut tape to be re-introduced into the tape outlet track;

[0013] Furthermore, a second cover plate and a third cover plate are respectively installed above the tape inlet track and the tape outlet track, so as to make the transmission track neater and smoother and avoid the tape from warping;

[0014] A sealing end assembly is also provided at the tail end of the tape outlet track of the transmission track substrate. The sealing end assembly includes an upper sealing end block and a lower sealing end block that are relatively arranged up and down at the outlet of the tape outlet track. Among them, the upper sealing end block is connected to an upper sealing end cylinder, and the lower sealing end block is connected to a lower sealing end cylinder below. The lower sealing end cylinder is installed on the lower surface of the transmission track substrate through a first suspension plate.

[0015] With the above structure, when the winding of the coiling machine is about to end, the bottom tape in the tape can be cut separately first, and then the whole tape can be cut, so that the film covering at the end of the wound tape protrudes from the bottom tape, which is also convenient for quickly peeling off the film covering and the bottom tape subsequently.

[0020] In an embodiment of the present invention, as Figures 1 to 6 shown, the present invention relates to a multi-layer multi-segment shearing mechanism 3 of a tape coiling machine, which includes a transmission track substrate 30 arranged at an inclined angle between a winding guiding mechanism 1 and a tape traction mechanism 2 of the tape coiling machine. The winding guiding mechanism 1 and the tape traction mechanism 2 are conventional technologies and will not be described in detail herein.

[0021] The overall transmission track substrate 30 is arranged in a horizontal inclined "T" structure. The high end of the transmission track substrate 30 has a tape inlet track 301 opposite to the outlet end of the tape traction mechanism 2, and the low end of the transmission track substrate 30 has a tape outlet track 302 opposite to the inlet end of the winding guiding mechanism 1. Between the tape inlet track 301 and the tape outlet track 302 on the transmission track substrate 30, there is a hollow connection section 303 that connects the two and runs through the transmission track substrate 30 vertically. At the starting end of the hollow connection section 303, a swing block 31 is installed. An active track 311 connected to the end of the tape inlet track 301 is provided on the swing block 31. The swing block 31 is driven by a swing drive cylinder 32 and its output swing shaft 321 installed on the lower surface of the transmission track substrate 30. The tape inlet track 301, the tape outlet track 302, and the active track 311 on the swing block 31 are arranged along the same straight-line transmission direction.

[0022] A first cover plate 33 is installed on the upper part of the hollow connection section 303 of the transmission track substrate 30. Vacuum adsorption holes 331 are provided on the first cover plate 33 and are connected to a vacuum adsorption nozzle (omitted in the figure). The position of the vacuum adsorption holes 331 corresponds to the film on the transmitted tape. When needed, the film on the tape is adsorbed through the vacuum adsorption holes 331 to separate the film from the base tape. After separation, the base tape bends downward into an inverted arch shape, so as to form a space for the upper blade of the shearing assembly to pass through between the film and the base tape, realizing the cutting of the base tape by the shearing assembly.

[0023] A shearing assembly 34 is also installed on the lower surface of the transmission track substrate 30, on the side of the tail end of the hollow connection section 303. The shearing assembly 34 includes a blade seat 341, a blade seat slide rail 342, a blade seat propulsion cylinder 343, and a shearing cylinder 344. An upper blade 345 and a lower blade 346 are provided on the blade seat 341. The output end of the shearing cylinder 344 drives the blade to perform shearing. Specifically, the blade seat propulsion cylinder 343 and the blade seat slide rail 342 are fixedly arranged on the lower surface of the transmission track substrate 30. The blade seat 341 is movably arranged on the blade seat slide rail 342 and is connected to the output end of the blade seat propulsion cylinder 343. The blade seat propulsion cylinder 343 can reciprocally drive the blade seat 341 and the blades thereon to run to the shearing position. The upper blade 345 is a fixed blade, arranged adjacent to the lower surface of the transmission track substrate 30. The lower blade 345 is a movable blade. The shearing cylinder 344 is installed below the tail end of the hollow connection section 303 through a second suspension plate 347 and its output end is arranged upward. When the blades on the blade seat 341 move to the shearing position, that is, when the upper and lower blades extend into the hollow connection section 303, the output end of the shearing cylinder 344 jacks upward to drive the lower blade 346 upward to shear with the upper blade 345.

[0024] Furthermore, the swing block 31 is in a right-angled bent shape, the movable track 311 is arranged on the outer corner surface of the swing block 31, and the starting end of the movable track 311 on the swing block 31 inclines downward; the output swing shaft 321 of the swing driving cylinder 32 is connected to the middle part of the vertical side of the swing block 31; in this way, when the swing block 31 rotates around the output swing shaft 321 towards the tail end direction, the starting end of the movable track 311 will not lift up the tape to cause tape jamming, which can ensure the continuous transmission of the tape, and during normal transmission, the starting end of the movable track 311 is lower and does not affect the tape transmission;

[0025] Furthermore, the starting end of the tape outlet track 302 has a guiding inclined surface 304 that inclines downward, which is convenient for the cut tape to be re-introduced into the tape outlet track 302. Since the tape has a certain hardness and the distance from the outlet end of the swing block 31 to the guiding inclined surface 304 is short, the tape can be smoothly introduced into the tape outlet track 302;

[0026] Furthermore, a second cover plate 36 and a third cover plate 37 are respectively installed above the tape inlet track 301 and the tape outlet track 302 to make the transmission track neater and smoother and prevent the tape from warping; a side cover 38 is also provided on the outer side of the transmission track substrate 30 to prevent the bottom tape cut during shearing from popping out and at the same time make the appearance tidier.

[0027] In the mechanism of the present utility model, electronic devices such as photoelectric sensors and counters are used for counting, identification, etc., and cover plates are arranged at appropriate positions to shield the interior for protection or dust prevention effects, etc., which will not be elaborated here.

[0028] The working process of the present utility model is as follows: During normal transmission, the movable track 311, the tape feeding inlet track 301, and the tape feeding outlet track 302 are on the same transmission plane; when the winding is about to be completed and the blank section of the tape runs to the swing block 31, after the swing block 31 rotates with the output swing shaft 321, the rear section of the movable track 311 swings downward and deviates from the original transmission path. At this time, the winding at the rear stops, while the tape traction mechanism 2 in the front continues to convey a section of the tape. At the same time, the film covering on the blank section of the tape is adsorbed and fixed by the vacuum adsorption holes 331, and the bottom tape of the tape will bend downward to form an inverted arch. The tape feeding stops. At this time, there is space for the upper blade 345 of the cutting assembly 34 to extend over and be located below the film covering and above the bottom tape, while the lower blade 346 is located below the bottom tape. At this time, the bottom tape can be cut separately. After cutting the bottom tape, the cutting assembly 34 returns, and then the winding is started again while the vacuum adsorption holes 331 stop adsorbing the film covering. The winding continues while the tape is conveyed for a certain distance. When the blank section is about to end, the winding mechanism stops winding again, while the tape traction mechanism 2 continues to convey the tape, causing the tape including the film covering to bend downward as a whole to form an inverted arch. At this time, the tape feeding stops, and then the cutting assembly 34 extends over again to cut the tape as a whole, and then the winding is continued to be completed; since the bottom tape is cut twice, the bottom tape between the two break points will automatically fall off, which makes a section of the film covering at the end of the wound tape longer than the bottom tape, providing convenience for subsequent peeling of the film covering and facilitating efficient operation of subsequent processes; after the winding is completed and the reel is replaced, the next winding operation is carried out; during this period, the swing block 31 returns to its original position, the cutting assembly 34 resets, and the tape pressing assembly 35 resets; the tape traction mechanism 2 conveys the tape again.

[0029] At the tail end of the tape feeding outlet track 302 of the transmission track substrate 30, there is also a sealing end assembly 35. The sealing end assembly 35 includes an upper sealing end block 351 and a lower sealing end block 352 that are relatively located up and down at the outlet of the tape feeding outlet track 302. Among them, the upper sealing end block 351 is connected to an upper sealing end cylinder 353, and the lower sealing end block 352 is connected to a lower sealing end cylinder 354 below; the lower sealing end cylinder 354 is installed on the lower surface of the transmission track substrate 30 through a first suspension plate 355; through the sealing end assembly 35, when the bottom tape and the protruding film covering that have completed layer-by-layer cutting are about to leave the tail end of the tape feeding outlet track 302, the lower sealing end cylinder 354 and the upper sealing end cylinder 353 respectively drive the lower sealing end block 352 and the upper sealing end block 351 to move relatively to clamp the bottom tape and the film covering and perform hot melt sealing at the end, so that the ends of the wound material are hot-pressed and adhered, or a sealing end label can be printed simultaneously.

[0030] In summary, through the above structure, when the winding of the winding machine is about to end, the present utility model can first cut the bottom tape in the tape separately and then cut the tape as a whole, so that the film covering at the end of the wound tape protrudes from the bottom tape, which is also convenient for subsequent rapid peeling of the film covering and the bottom tape.

[0031] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
