Description

Technical Field

[0001] The utility model belongs to the field of carrier tapes, and in particular relates to a carrier tape positioning punching die. Background Art

[0002] Carrier tape refers to a strip product used in the field of electronic packaging. It has a specific thickness and is equidistantly distributed along its length with holes (also called pockets) for holding electronic components and positioning holes for indexing and positioning. A center hole is opened in the center of the pocket. The carrier tape has very strict requirements on the accuracy of the punching positions of its positioning holes and center hole, especially the center hole. The deviation of the punching position seriously affects the progress of the next process and may even cause product defects.

[0003] The micro-part carrier punching die, with publication number CN214686930U, includes a die base, a punching positioning plate, a guide post, a needle suspension, a needle pressure plate, and a die connection seat. The die connection seat is screwed onto the needle suspension, the guide post is mounted on the top of the die base, and the needle suspension is movably mounted on the outer wall of the guide post via a guide sleeve. A mounting slot is longitudinally provided in the middle of the needle suspension. The size of the needle pressure plate is consistent with that of the mounting slot, and the needle pressure plate is located in the mounting slot. A movable slot 1 is longitudinally provided on both the left and right sides of the mounting slot, and a guide rail is installed on the inner wall of the movable slot 1. The front and back of the die base are respectively installed with an entry track and an exit track, and a punching drive wheel is installed on the top of the exit track. Like the current common carrier tape punching dies, it uses rollers to pull the carrier tape, and positions the carrier tape through tracks or grooves. After the carrier tape is pulled to the punching position, the pulling of the carrier tape is stopped, and then the punching operation is performed. Although this method has tracks or grooves to position the carrier tape on the left and right sides of the conveying direction, thereby improving the punching accuracy, it is unable to position the pockets on the front and back sides of the movement direction. In addition, there is a problem of uneven tension when the roller pulls the carrier tape. When the traditional carrier tape punching die encounters this situation, it will cause the front and back positions of the carrier tape punching to shift. In addition, the vibration of the machine itself during operation will also cause the punching position to shift. The above problems cannot be well solved in the current carrier tape punching die, and the punching accuracy needs to be improved. Utility Model Content

[0016] The beneficial effects of the utility model are:

[0017] 1. By setting the bumps, the pockets are fixed in position before punching, ensuring punching accuracy. Simply setting the bumps not only solves the problem of punching position offset caused by the traditional lack of front and rear positioning of the pocket in the conveying direction, because the bumps hold the pockets down, which is equivalent to positioning the pockets front, back, left, and right during punching; it also solves the problem of pocket position offset caused by uneven tension. Even if the pocket position is offset due to uneven tension, the pocket position will be automatically corrected during the downward movement of the bumps. It also solves the problem of punching position offset caused by machine vibration, because the bumps have already pressed the pockets against the positioning guide grooves, preventing them from offsetting even when subjected to vibration. Using bumps to directly position the pockets greatly improves punching accuracy without the need for complex structures.

[0018] 2. The center lines of each first perforation and each second perforation are arranged to be collinear. In terms of the punching needle group, the accuracy of the punching position is guaranteed. The arrangement of the first perforation and the second perforation not only allows the first needle and the second needle to pass through, but also positions and guides the first needle and the second needle to avoid tilting of the first needle and the second needle, thereby ensuring the accuracy of punching.

[0019] 3. Use the pressing block to position the carrier tape at the location of the positioning hole to ensure the punching accuracy of the positioning hole.

[0020] 4. The setting of the frustum hole and the discharge port is more conducive to the discharge of waste.

[0021] 5. Through the setting of guide columns and guide holes, guiding positioning is carried out to further improve the punching accuracy.

[0022] 6. The chamfered portion is more conducive to the correction of the pocket position by the protrusion, further improving the punching accuracy.

[0023] 7. By setting the width of the supporting ridges smaller than the width of the positioning guide grooves, the contact surface between the pocket and the supporting ridges is reduced, friction is reduced, and punching accuracy is further improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0036] Any content not described in detail in this specification belongs to the prior art known to those skilled in the art. In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," and the like, indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely for the purpose of facilitating the description of the utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the utility model. Furthermore, the terms "first," "second," and "third," etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0037] like Figures 1 to 10 As shown, a carrier tape positioning punching die provided in this embodiment includes an upper die 1 and a lower die 2 that cooperate with each other. The lower die 2 is provided with a guide plate 3 and a limit plate 4. The limit plate 4 is located above the guide plate 3 and forms a conveying channel 5 for the carrier tape to pass through between the limit plate 4 and the guide plate 3. The top of the guide plate 3 has a plurality of positioning guide grooves 6 for conveying and guiding the carrier tape at intervals along its length. The upper die 1 is provided with a pressing plate 7. The bottom of the pressing plate 7 has a plurality of protrusions 8 that act on the pockets of the carrier tape to position the pockets of the carrier tape. A punching needle group 9 is provided in the middle of the upper die 1. When punching, the punching needle group 9 passes through the protrusion 8. The top of the upper die 1 of this embodiment is detachably connected to a connecting seat connected to a driving member that drives the upper die to move up and down.

[0038] The present invention also uses rollers to pull the carrier belt to perform punching operations, positioning the left and right sides of the bag in the conveying direction via the positioning guide groove 6. Furthermore, the provision of the protrusion 8 allows the bag to be fixed in position before punching, ensuring punching accuracy. The provision of the protrusion 8 alone not only solves the problem of offset punching positions caused by the lack of front and rear positioning of the bag in the conveying direction, because the protrusion 8 holds the bag in place, effectively positioning the front, rear, left, and right sides of the bag during punching; it also solves the problem of offset punching positions caused by uneven tension. Even if the pocket position shifts due to uneven tension, the downward movement of the protrusion 8 automatically corrects the pocket position. It also solves the problem of offset punching positions caused by machine vibration, because the protrusion 8 presses the bag against the positioning guide groove 6, preventing the bag from shifting even when subjected to vibration. Using the protrusion 8 to directly position the bag significantly improves punching accuracy without the need for complex structures.

[0039] In this embodiment, six pressing blocks 10 are fixed to the bottom of the pressing plate 7 at equal intervals along its length, and four protrusions 8 are fixed to the right side of the bottom of the pressing block 10 at equal intervals along its length. The upper mold 1, the pressing plate 7, the pressing block 10, the protrusion 8, and the guide plate 3 all have a perforation group 11 for the punching needle group 9 to pass through. The perforation group 11 includes six groups of perforations arranged at equal intervals, each group of perforations includes four first perforations 111 and four second perforations 112, the four first perforations 111 and the four second perforations 112 are arranged side by side, the center lines of the first perforations 111 of the upper mold 1, the pressing plate 7, the pressing block 10, the protrusion 8, and the guide plate 3 are collinear, the center lines of the second perforations 112 of the upper mold 1, the pressing plate 7, the pressing block 10, the protrusion 8, and the guide plate 3 are collinear, the punching needle group 9 includes six groups of punching needles arranged at equal intervals, each group of punching needles includes four first needles 91 and four second needles 92, the four first needles 91 and the four second needles 92 are arranged side by side, the first perforations 111 are for the first needles 91 to pass through, and the second perforations 112 are for the second needles 92 to pass through. The top of the pressing plate 7 has a groove 12. The pressing plate 7, the pressing block 10, and the protrusion 8 all have a first through-hole 111. The first through-hole 111 of the pressing plate 7 communicates with the groove 12 and the first through-hole 111 of the pressing block 10, respectively. The first through-hole 111 of the protrusion 8 passes through the upper and lower side walls of the protrusion 8 and communicates with the first through-hole 111 of the pressing block 10. The pressing plate 7 and the pressing block 10 both have a second through-hole 112. The second through-hole 112 of the pressing block 10 passes through the upper and lower side walls of the pressing block 10 and communicates with the second through-hole 112 of the pressing plate 7. The second through-hole 112 of the pressing plate 7 communicates with the groove 12. The bottom end of the first through-hole 111 of the guide plate 3 passes through the bottom wall of the guide plate 3, and its top end communicates with the positioning guide groove 6. The second through-hole 112 of the guide plate 3 passes through the upper and lower walls of the guide plate 3. Therefore, this embodiment can punch six carrier tapes at a time. In other embodiments, nine, twelve, and so on can also be punched at a time. The center hole of the pocket is punched by the first needle 91, and the positioning hole of the carrier tape is punched by the second needle 92. The carrier tape to be punched is conveyed and guided by the conveying channel 5. Combined with the setting of the pressure plate 7, the carrier tape is guided and positioned before punching. After positioning, the punching needle group 9 performs synchronous punching operations on multiple carrier tapes at once, which not only has high punching accuracy but also high punching efficiency. The center lines of each first perforation 111 and the center lines of each second perforation 112 are collinear. In terms of the punching needle group 9, the accuracy of the punching position is guaranteed. The setting of the first perforation 111 and the second perforation 112 not only allows the first needle 91 and the second needle 92 to pass through, but also positions and guides the first needle 91 and the second needle 92 to avoid tilting of the first needle 91 and the second needle 92, thereby ensuring the accuracy of punching. The carrier tape at the position of the positioning hole to be punched is positioned by the pressure block 10 to ensure the accuracy of the punching of the positioning hole.

[0040] The first through-hole 111 and the second through-hole 112 of the guide plate 3 each include a cylindrical hole 13 and a conical hole 14 disposed at the bottom of the cylindrical hole 13. The lower mold 2 has a discharge port 15 in the middle, which is located below the conical hole 14. The arrangement of the conical hole 14 and the discharge port 15 further facilitates the discharge of waste.

[0041] Among them, it also includes a guide sleeve 16, a guide rod 17, a first connecting member 18, a second connecting member 19, and a spring 20. The guide sleeve 16 is fixed at the four corners of the upper mold 1, and the guide rod 17 is fixed at the four corners of the lower mold 2. The guide rod 17 passes through the pressure plate 7 and the guide sleeve 16. The left and right sides of the pressure plate 7 are provided with a first connecting member 18. The top of the first connecting member 18 passes through the pressure plate 7 and is connected to the bottom of the upper mold 1. The bottom end of the first connecting member 18 is a free end and is located below the pressure plate 7. The front and rear sides of the pressure plate 7 are provided with a second connecting member 19. The front and rear sides of the upper mold 1 both have an accommodating space 21. The bottom end of the second connecting member 19 passes through the upper mold 1 and is connected to the top of the pressure plate 7. The top of the second connecting member 19 is a free end and is located in the accommodating space 21. The first connecting member 18 and the second connecting member 19 are surrounded by a spring 20, and the spring 20 is located between the upper mold 1 and the pressure plate 7. The first connecting member 18 and the second connecting member 19 have the same structure, both including a head 22, a rod 23, and a threaded portion 24. The head 22 and the threaded portion 24 are connected by the rod 23. The first connecting member 18 is screwed to the upper mold 1 through the threaded portion 24, and the second connecting member 19 is connected to the pressure plate 7 through the threaded portion 24. The free ends of the first connecting member 18 and the second connecting member 19 are both the head 22. The setting of the guide rod 17 and the guide sleeve 16 makes the up and down movement of the punching needle group 9 more stable. During the downward movement of the upper mold 1, the pressure plate 7 follows the downward movement. The pressure plate 7 first hits the lower mold 2. When the upper mold 1 continues to move downward, the spring 20 contracts, and the pressure plate 7 is pressed against the top of the lower mold 2. The punching needle group 9 passes through the pressure plate 7, the pressure block 10, and the protrusion 8, and punches the carrier tape. After punching is completed, the upper mold 1 moves upward, driving the pressure plate 7 to move upward, causing the punching needle group 9 to move upward and leave the carrier tape, and the spring 20 extends and resets, driving the pressure plate 7 to reset. Through the setting of the first connecting member 18 and the second connecting member 19, not only the smoothness of the up and down movement of the pressure plate 7 is improved, but also the movement position of the pressure plate 7 is limited to prevent the pressure plate 7 from detaching.

[0042] The pressure plate 7 has guide holes 25 on its left and right sides, and the top of the limit plate 4 has guide posts 26 that cooperate with the guide holes 25. The middle of the limit plate 4 has six through holes 27 evenly spaced along its length for the pressure block 10 to pass through. The guide posts 26 and guide holes 25 provide guidance and positioning, further improving punching accuracy.

[0043] Among them, the front, back, left and right sides of the bottom of the projection 8 are all provided with chamfered portions 28. The provision of the chamfered portions 28 is more conducive to the correction of the pocket position by the projection 8, further improving the punching accuracy.

[0044] The positioning guide groove 6 extends through the front and rear walls of the guide plate 3. A supporting ridge 29 is provided at the center of the inner bottom of the positioning guide groove 6. The width of the supporting ridge 29 is smaller than that of the positioning guide groove 6. By making the width of the supporting ridge 29 smaller than that of the positioning guide groove 6, the contact surface between the pocket and the supporting ridge 29 is reduced, friction is reduced, and punching accuracy is further improved.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
