Description

Technical Field

[0001] This invention belongs to the field of electronic component packaging equipment, and more specifically to the field of chip resistor packaging equipment. In particular, it relates to a resistor tape winding mechanism and its usage method. Background Technology

[0002] After being braided, resistor tapes are obtained. Resistor tapes longer than 5 meters are wound using a plastic reel as the central axis before packaging and shipping. Resistor tapes shorter than 5 meters do not have a plastic reel and must be wound into hollow circles before being placed in sealed plastic bags for packaging and shipping. Figure 1-3 As shown.

[0003] For resistor tape products shorter than 5 meters, the current technology involves manual winding, with the outermost ring secured with tape after manual winding. Manual winding cannot guarantee a consistent outer diameter for products of the same length, nor can it guarantee a consistent outer diameter for products of different lengths. Furthermore, manually wound products are not perfectly round. Therefore, manual winding affects the product's aesthetics and consistency, and is also slow.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0005] The technical problem to be solved by this invention is to address the issue that the manual hollow-circle winding of resistance strips shorter than 5 meters results in inconsistent outer diameters, difficulty in roundness control, low winding efficiency, and poor quality consistency after winding resistance strips of different lengths.

[0006] The inventive concept of this invention is to design an automatic winding mechanism for resistor carrier tape. This mechanism uses a variable-diameter shaft as the winding shaft, selecting different speed settings for resistor carrier tapes of different lengths. Manual feeding is used, the machine is started for automatic winding, and it stops automatically after winding. The wound tape is then manually removed, and the outermost ring is manually secured with adhesive tape. This achieves the goal of ensuring that resistor carrier tapes of different lengths have approximately the same outer diameter after being wound into a product, improving the consistency of the outer diameter, roundness, winding efficiency, and overall quality.

[0007] Therefore, the present invention provides a resistance tape winding mechanism, such as... Figure 4-10 As shown. Includes: 2. Variable diameter shaft core, 3. Limit plate positioning block, 4. Foot switch, 5. PLC controller, 6. Servo controller, 7. Tension spring, 8. Frame housing, 9. Feeding limit mechanism, 10. Sensor mounting bracket, 11. Sensor, 12. Linear bearing seat, 13. Equipment platform, 14. Guide shaft, 15. Limit plate, 16. Clamping block, 17. Servo motor, 18. Torsion spring, 19. Servo motor mounting base.

[0008] The variable diameter shaft 2 has multiple (two or more) discs with variable diameter shaft limiting holes A4 of different diameters, designed to accommodate resistor strips of different lengths. Each disc has multiple (two or more) variable diameter shaft limiting holes A4 (the spacing between the limiting holes A4 is evenly distributed around the circle) for different resistor sizes. The limiting holes A4 are used to fix the head of the resistor strip. The variable diameter shaft is designed with multiple discs of different diameters to accommodate resistor strips of various lengths. The operator selects different settings based on the resistor strip length, with different diameter discs corresponding to different settings. To ensure that the outer diameters of resistor strips of different lengths are approximately the same after winding, the longest resistor strip has the smallest inner diameter after winding, so the smallest circle setting (lowest setting) of the variable diameter shaft is selected; while the shortest resistor strip has the largest inner diameter after winding, so the largest circle setting (highest setting) is selected; other lengths are sequentially adjusted inwards (one setting corresponds to one length range). The tail of the variable diameter shaft is connected to the shaft of the servo motor. It is designed with a shaft hole structure that can be tightened and loosened and can be limited, and is fixed by bolt tightening.

[0009] The positioning block 3 of the limiting plate is L-shaped with a rectangular bottom surface for fixing to the equipment platform 13. The vertical surface is trapezoidal with multiple (more than two) grooves at the top of the trapezoid. Each groove is a level, corresponding to different lengths of resistor strips. The lowest level corresponds to the smallest circular level (level 1), and the highest level corresponds to the largest circular level. This is used to fix the limiting plate 15, so that the limiting plate 15 is supported and fixed at each level.

[0010] The foot switch 4 is used by the operator to start and stop the equipment.

[0011] The PLC controller 5 is used as the PLC program controller for the equipment.

[0012] The servo controller 6 is used to control the servo motor.

[0013] The tension spring 7 is used to tighten the limiting plate, providing tension to press the limiting plate against the product side.

[0014] The rack housing 8 is used to provide overall support and enclosure for the equipment.

[0015] The feeding limiting mechanism 9 is provided with a preliminary limiting hole A1, which is used for the product to pass through the preliminary limiting hole A1 of the mechanism, and can prevent the product from swinging left and right and flipping.

[0016] The sensor mounting bracket 10 is used to mount the sensor 11 and also provides a sensor detection limiting hole A2 through which the product passes.

[0017] The sensor 11 is used to detect the presence or absence of a product; if no product is present, the program controls the automatic shutdown.

[0018] The linear bearing housing 12 is used to install and fix the guide shaft.

[0019] The device platform 13 provides a platform for component installation.

[0020] The guide shaft 14 is used to connect the limiting plate 15 and the linear bearing seat 12, and can be manually operated to move back and forth to select the gear.

[0021] The limiting plate 15 is a hollow mechanism used to prevent the product from shifting left or right during winding. It has bolt clamping limiting holes A3 on it; the resistor strip product passes through the clamping limiting holes A3, which helps to hold the resistor strip product in place. It also serves to fix the clamping block 16.

[0022] The clamping block 16 is used to clamp the product when the servo rotates the tape winding, and the pressure is greater when it works with the torsion spring 18.

[0023] The servo motor 17 is used to drive the variable diameter shaft core to rotate and wind the tape. When the servo is selected, because the servo has the function of stopping and braking, it will not continue to rotate due to inertia or rotate in the opposite direction due to tension, which would cause the finished tape to loosen.

[0024] The torsion spring 18 is used to cooperate with the clamping block 16 to increase the pressure on the product (the product itself has a certain hardness and elasticity).

[0025] The servo motor mounting bracket 19 is used to fix the servo motor on the desktop.

[0026] The method of using the aforementioned resistance tape winding mechanism is as follows: (1) Using manual feeding, the resistor strip product is passed through the initial limiting hole (A1) from head to tail. For example... Figure 5 and Figure 11 As shown.

[0027] (2) Pass the resistive strip product through the sensor detection limit hole (A2) from head to tail to limit the product and perform photoelectric sensor to detect whether the product is present or not.

[0028] (3) Pass the resistor strip through the clamping and limiting hole (A3) from head to tail; (pass it through the two limiting bolts of the limiting clamping plate to prevent the resistor strip from loosening and bouncing up when rotating due to excessive elasticity).

[0029] (4) Pass the resistor strip product through the variable diameter shaft core limiting hole (A4) in the head-to-tail direction and clamp the head of the resistor strip product.

[0030] (5) Start the resistance tape winding mechanism to make the variable diameter shaft rotate and drag the resistance tape winding to rotate.

[0031] (6) After the roll is finished, the equipment will stop automatically. Then, the rolled tape is removed manually, and the outermost ring is fixed manually with tape.

[0032] The variable diameter shaft allows manual selection of different gear positions for the tape winding, and the limiting plate positioning block 3 provides a fixed support for achieving gear selection.

[0033] Advantages of this equipment: ① By selecting different variable diameter shaft settings, the outer diameter of the resistor tape of different lengths can be made to be approximately the same (around 80mm).

[0034] ② No manual pressing is required when winding the tape, realizing the elimination of manual operation for resistor tape winding without plastic reels. Previously, manual winding was required, and other similar small devices required manual tightening of the resistor tape winding.

[0035] ③ The equipment can detect the presence or absence of products and automatically stops when the tape winding ends, requiring no human supervision during the winding process.

[0036] ④ The products rolled by this equipment have high roundness and will not deform.

[0037] ⑤ The speed is adjustable; the speed of the tape winding can be adjusted by adjusting the speed of the servo motor.

[0038] This invention can be used for rolls of strip-shaped packaged products, such as resistor tapes or other similar electronic component tapes. Attached Figure Description

Detailed Implementation

[0052] like Figure 1 As shown, the specific implementation method of the resistor tape winding mechanism and its usage is as follows: The sensor 11 is a photoelectric sensor.

[0053] The clamping block 16 is racket-shaped.

[0054] The variable diameter shaft 2 has six discs with limiting holes of different diameters. Each disc has four limiting holes (evenly distributed at 90° intervals) for fixing the head of the resistance strip. The variable diameter shaft is designed with six discs of different diameters to accommodate six different lengths of resistance strip. The operator selects different settings according to the length of the resistance strip, with six different diameter discs corresponding to six settings. To ensure that the outer diameter of resistance strips of different lengths is approximately the same after winding (around 80mm, typically 70mm-90mm), the longest resistance strip has the smallest inner diameter after winding, so the smallest setting (setting 1) of the variable diameter shaft is selected; while the shortest resistance strip has the largest inner diameter after winding, so the largest setting (setting 6) of the variable diameter shaft is selected; other lengths are sequentially adjusted inwards (one setting corresponds to one length range). The tail of the variable diameter shaft connects to the shaft of the servo motor and is designed with a shaft hole structure that can be tightened and loosened and limited, and is fixed with bolts.

[0055] The positioning block 3 of the limiting plate is used to fix the limiting plate 15, so that the limiting plate 15 is supported and fixed in the six positions.

[0056] For the A2 sensor detecting the limit hole: the equipment will stop rotating after a 0.5-second delay when there is no product.

[0057] The variable diameter shaft allows manual selection of 6 winding positions.
