Description

Technical Field

[0001] This utility model relates to the field of carrier tape winding technology, specifically to a carrier tape winding device for electronic components. Background Technology

[0002] Carrier tape refers to a strip-shaped product used in the field of electronic packaging. It has a specific thickness and has holes for holding electronic components and positioning holes for indexing and positioning distributed evenly along its length. These carrier tapes are produced in large quantities and cannot be placed randomly. They must be wound up and stored using a winding device.

[0003] Patent document CN214692395U discloses an improved carrier tape winding device, including a base and a limiting plate. A control switch is fixedly installed on the upper left side of the base, and a column is welded to the upper middle of the base. A through groove is formed at the upper end of the column, and a straight rod is arranged in the inner cavity of the through groove. A first pulley is fixedly installed at the right end of the straight rod. A motor is fixedly installed on the upper right side of the base, and a transmission rod is arranged on the left side of the motor. The output end of the motor shaft is connected to the transmission rod. This utility model controls the width of the carrier tape winding by using a straight rod, threads, a limiting plate, and a threaded groove, thereby improving practicality and facilitating the removal of the wound carrier tape. The use of a strip frame, spring, and rubber plate prevents wrinkles from forming on the carrier tape during winding, further improving winding efficiency. It is practical and suitable for widespread promotion and use.

[0004] However, when the above-mentioned utility model is used, since there is no limiting device for the straight rod, if there is carrier tape wound on the straight rod when the motor is not working, the straight rod may be rotated due to accidental contact by the staff, which will cause the carrier tape to be unwound from the straight rod, causing unnecessary trouble for the staff. Therefore, a new electronic component carrier tape winding device is proposed to optimize the above-mentioned existing technology. Utility Model Content

[0018] 4. The second fixing plate of this utility model is combined with the positioning groove and positioning pin, and can also be combined with the first fixing plate. It is further locked and fixed by connecting piece and fixing bolt to form a whole. At the same time, the insertion of hexagonal plug and hexagonal slot makes rotation limit between the first winding shaft and the second winding shaft, and between the second winding shafts. Thus, multiple driven winding mechanisms can be extended on the outside of the first base plate, driven by a motor, to wind up multiple carrier tapes at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Please see Figures 1-4In this embodiment of the present invention, an electronic component carrier tape winding device includes a first base plate 1. The first base plate 1 has a first upright plate 2 fixedly connected to one side of its top surface. A pressing mechanism 3 is connected to the middle of one side of the first upright plate 2. A U-shaped groove 4 is fixedly connected to the top of the other side of the first upright plate 2. A first winding shaft 5 is rotatably connected to the U-shaped groove 4 and the first upright plate 2. A limiting mechanism 6 is connected to one end of the first winding shaft 5 located above the pressing mechanism 3. A worm gear 7 is fixedly sleeved inside the U-shaped groove 4. A worm 8 meshes with the worm gear 7 on its outer side. Both ends of the worm 8 are rotatably installed with the U-shaped groove 4. A motor 9 is fixedly installed at the bottom of the U-shaped groove 4 corresponding to the end of the worm 8. The motor 9 is externally connected to a power supply and a switch. The output end of the motor 9 is fixedly connected to the worm 8. The pressing mechanism 3 includes a frame 10, a spring 11, and a pressing plate 12. The limiting mechanism 6 includes a limiting disc 13, a convex key 14, and a hand-tightening bolt 15.

[0028] The motor 9 drives the worm gear 8 to rotate, which in turn drives the worm wheel 7 to rotate, thereby driving the first take-up shaft 5 to take up the carrier belt. The principle that the worm wheel 7 cannot drive the worm gear 8 to rotate in the opposite direction creates a self-locking effect, which effectively prevents workers from accidentally touching the straight rod and causing it to rotate, which would result in the carrier belt being unwound from the straight rod and causing unnecessary trouble for the workers.

[0029] The frame 10 is fixedly connected to the first upright plate 2. The extrusion plates 12 are symmetrically arranged on the inner side of the frame 10. The springs 11 are evenly arranged between the extrusion plates 12 and the frame 10. One end of the spring 11 is fixedly connected to the extrusion plate 12, and the other end of the spring 11 is fixedly connected to the inner wall of the frame 10.

[0030] Based on the elasticity of the spring 11, the spring 11 pushes the extrusion plate 12 to move towards the center. The extrusion plate 12 applies a reaction force to the winding carrier tape, thereby stretching the carrier tape and preventing wrinkles from forming during winding, thus further improving winding efficiency.

[0031] The limiting disc 13 is sleeved on the outside of the first take-up shaft 5. A keyway 16 is provided on the circumference of the first take-up shaft 5. A convex key 14 is slidably connected in the keyway 16 and fixedly connected to the inner wall of the center hole of the limiting disc 13. The limiting disc 13 slides on the first take-up shaft 5 through the cooperation of the convex key 14 and the keyway 16. A hand-tightening bolt 15 is threadedly connected to the limiting disc 13 and passes through the limiting disc 13 against the outer wall of the first take-up shaft 5. A threaded hole for threaded connection of the hand-tightening bolt 15 is provided on the limiting disc 13.

[0032] The limiting plate 13 slides on the first winding shaft 5 through the cooperation of the keyway 16 and the convex key 14, and is locked and fixed with the hand-tightening bolt 15, thereby controlling the width of the carrier tape winding and further improving its practicality.

[0033] Example 2:

[0034] Please see Figure 5 In this embodiment of the present invention, an electronic component carrier tape winding device further includes a driven winding mechanism, which is disposed on the outside of the first base plate 1. The driven winding mechanism includes a second base plate 17, a second vertical plate 18, and a second winding shaft 19.

[0035] The second upright plate 18 is fixedly connected to the top surface of the second base plate 17. The second take-up shaft 19 is rotatably connected to the top of the second upright plate 18. The middle part of the second upright plate 18 is also connected to the extrusion mechanism 3. The frame 10 is fixedly connected to the second upright plate 18. The second take-up shaft 19 is also connected to the limit mechanism 6. The second take-up shaft 19 is also provided with a keyway 16 that matches the convex key 14.

[0036] A positioning groove 20 is provided on one side of the second base plate 17, and a positioning pin 21 is fixedly connected to the other side of the second base plate 17. A positioning groove 20 is also provided on the side of the first base plate 1 close to the second base plate 17. The positioning groove 20 corresponds to and is compatible with the positioning pin 21. A connecting piece 22 is fixedly connected to the top surface of the side of the second base plate 17 corresponding to the positioning pin 21. A fixing bolt 23 passes through the connecting piece 22. A round hole for the fixing bolt 23 to pass through is provided on the connecting piece 22. The fixing bolt 23 is inserted into the corresponding first base plate 1 or second base plate 17 and is threadedly connected to the first base plate 1 and the second base plate 17. Threaded holes are provided at the connection points of the fixing bolt 23 on the plates 1 and the second base plate 17.

[0037] One end of the second take-up spool 19 is fixedly connected to a hexagonal plug 24, and the other end of the second take-up spool 19 is provided with a hexagonal slot 25. The end of the first take-up spool 5 near the second take-up spool 19 is also provided with a hexagonal slot 25. The hexagonal slot 25 corresponds to and is compatible with the hexagonal plug 24. The insertion of the hexagonal plug 24 and the hexagonal slot 25 forms a limitation for rotation.

[0038] The second fixing plate 17 is combined with the positioning groove 20 and the positioning pin 21, and can also be combined with the first fixing plate 1. It is further locked and fixed by the connecting piece 22 and the fixing bolt 23 to form a whole. At the same time, the hexagonal plug 24 and the hexagonal slot 25 are inserted into each other, so that rotation is limited between the first winding shaft 5 and the second winding shaft 19, and between the two winding shafts 19. Thus, multiple driven winding mechanisms can be extended on the outside of the first base plate 1, driven by a motor, to wind up multiple carrier tapes at the same time.

[0039] The working principle of this utility model is as follows:

[0040] In use, the driven winding mechanism is connected to the first base plate 1. The second base plate 17 is then fitted against the first base plate 1 and positioned using the interlocking of the positioning groove 20 and positioning pin 21. The fixing bolt 23 is rotated, and the first base plate 1 and the second base plate 17 are connected together via the connecting piece 22. The first winding shaft 5 and the second winding shaft 19 are then connected via the interlocking of the hexagonal plug 24 and hexagonal slot 25, further connecting the driven winding mechanisms. The second base plates 17 are brought closer together and positioned using the interlocking of the positioning groove 20 and positioning pin 21. The fixing bolt 23 is rotated, and the spliced ​​second base plates 17 are connected together via the connecting piece 22. The hand-tightening bolt 15 is then loosened, and the limiting disc 13 slides on the first winding shaft 5 and the second winding shaft 19 via the cooperation of the convex key 14 and keyway 16. Adjust the width to fit the carrier belt, then rotate the hand-tightening bolt 15 again to abut against the outer wall of the first take-up shaft 5 and the second take-up shaft 19, so that the position of the limiting plate 13 is limited. At this time, the carrier belt to be wound is passed through the middle of the extrusion plate 12 and connected to the first take-up shaft 5 and the second take-up shaft 19. The extrusion plate 12 is pushed by the spring 11 to clamp the carrier belt, forming a tension effect. At this time, the motor 9 is started. The motor 9 drives the worm wheel 7 through the worm 8, thereby causing the first take-up shaft 5 to rotate, thereby realizing the rotation of the carrier belt. Through the cooperation of the hexagonal plug 24 and the hexagonal slot 25, the first take-up shaft 5 synchronously drives the second take-up shaft 19 to rotate. At the same time, the second take-up shaft 19 synchronously drives the adjacent second take-up shaft 19 to rotate through the cooperation of the hexagonal plug 24 and the hexagonal slot 25, thereby performing synchronous winding of multiple carrier belts.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
