Description

Technical Field

[0001] The present invention relates to the precision machining technology of intelligent product connectors, and particularly to a driving device for separately feeding a strip and a paper tape and a using method thereof. Background Art

[0002] The precision machining process of intelligent product connectors mainly includes stamping, cleaning, electroplating, injection molding, assembly, shearing, CCD detection, packaging, etc. The characteristics of intelligent product connectors are that the parts are very small, the quantity is very large, and the types are particularly numerous, etc. It is impossible to process single loose parts at low cost, and continuous material processing is required, which uses a large amount of strip, carrier tape, paper tape, etc. The paper tape is wound into the glue tray together with the strip to protect the parts in the strip. When reprocessing these parts such as electroplating, assembling, packaging, etc., the strip needs to be fed. When feeding, on the one hand, the strip enters the automatic machine for operation, and on the other hand, the released paper tape needs to be recovered and wound into the glue tray at the same time. The most ideal state is that the length of the strip fed into the automatic machine is the same as the length of the paper tape recovered and wound into the glue tray at any time, so as to keep the length of the released strip consistent with the length of the paper tape recovered and wound into the glue tray. However, in most cases now, such a standard has not been achieved. Because when feeding, the diameter of the strip in the strip glue tray becomes smaller and smaller, while the diameter of the paper tape in the paper tape glue tray becomes larger and larger, it is impossible to realize equal-length feeding of the strip and winding of the paper tape. Sometimes, the paper tape in the strip tray tightly presses the strip, resulting in the parts being pressed and deformed. Therefore, to avoid this situation, manual intervention is required continuously to keep them consistent, which will reduce the degree of automation.

[0003] Chinese Patent Publication No. CN105858320A discloses an automatic feeding device for a wound strip. The wound strip includes a strip formed by connecting a plurality of electronic components one by one and a paper tape encapsulating and covering the strip. The strip encapsulated with the paper tape is integrally wound on a material tray. The automatic feeding device includes a machine table, a material tray bracket arranged on the machine table for hanging the material tray, a paper tape collecting tray arranged on the machine table for pulling and winding the paper tape, and it further includes a controller arranged in the machine table, a linear feeding track, a fixed-distance transfer mechanism, a cutting mechanism, and a linear vibration feeding mechanism which are all arranged on the machine table and arranged in sequence along the feeding direction. The controller is controlled to connect the fixed-distance transfer mechanism, the cutting mechanism, and the linear vibration feeding mechanism. This device does not consider the problems brought by the unequal feeding lengths of the paper tape and the strip.

[0004] Chinese Invention Patent Publication No. CN113371488A discloses a stamping strip automatic rewinding machine and its operation method, including a buffer tower, a strip feeding mechanism, a cutting mechanism, a turntable rewinding mechanism, a driven disk mechanism, a dispensing mechanism, a shearing mechanism, a paper tape feeding mechanism, a tape sticking mechanism, a manipulator handling mechanism, a labeling mechanism, and an appearance sampling mechanism. The strip passes through the buffer tower and the strip feeding mechanism and then enters the turntable rewinding mechanism. The paper tape feeding mechanism feeds the paper tape into the turntable rewinding mechanism. The turntable rewinding mechanism rewinds the strip and the paper tape together onto the paper disk. This patent is for the rewinding rather than the unwinding of the strip and the paper tape.

[0005] Chinese Utility Model Patent Publication No. CN214706556U discloses a synchronous unwinding device for a pin inserting machine, which is used to synchronously unwind the pin inserting strip and the paper tape. It includes a bracket and one or more synchronous unwinding components arranged on the bracket. The synchronous unwinding component includes a motor, a main shaft connected to the output shaft of the motor and driven by the motor to rotate, a unwinding reel synchronously rotating with the main shaft, a main connecting block connected to the motor body, a sub-connecting block connected to the main connecting block, two guide rails fixedly connected to the sub-connecting block, a mounting block slidably connected to the two guide rails, and a sub-shaft arranged on the mounting block. The sub-shaft can rotate freely relative to the mounting block. This device also does not consider the problem caused by the unequal unwinding lengths of the paper tape and the strip.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] A tape and paper tape equal-length feeding drive device mainly consists of an installation total bracket 2, a paper tape tensioning mechanism 3, a paper tape driving mechanism 5, a paper tape guiding assembly 6, a paper tape recycling assembly 7, a part glue disk assembly 8, as well as a tape 1 and a paper tape 4, as shown in Figure 1 the figure. The main feature of this device is that during feeding, the length of the tape entering the automatic machine is always consistent with the length of the paper tape entering the second glue disk, without any excess tape or long paper tape that may affect automated production.

[0032] The paper tape tensioning mechanism 3 mainly consists of a roller assembly 30, a positioning piece 31, a swing rod 32, a first torsion spring 33, a second micro-bearing 34, a rotating shaft 35, a fixed seat 36, a photoelectric switch BB, and a photoelectric switch CC, as shown in Figure 2 . The positioning piece is installed on the swing rod; the second micro-bearing is installed on the rotating shaft; among them, the roller assembly 30 consists of a third snap ring 46, a third micro-bearing 47, a roller 48, a limit sleeve 49, and a second roller shaft 51, as shown in Figure 3 . The paper tape tensioning mechanism 3 is rigidly connected to the installation total bracket 2 through the fixed seat 36 with fasteners. The rotating shaft 35 is in interference fit with the fixed seat. The bearing sleeve 52 is connected to the rotating shaft 35 through the second micro-bearing 34. The swing rod 32 is connected to the bearing sleeve with fasteners. Both the roller assembly 30 and the positioning piece 31 are fixed on the swing rod 32 with fasteners. The first torsion spring 33 is sleeved on the outer circle of the bearing sleeve 52. One end of the first torsion spring is inserted into a hole on the outer circle of the bearing sleeve, and the other end is hooked on one side of the swing rod 32. The adjusting sleeve is sleeved on the rotating shaft 35, which not only limits the first torsion spring but also can adjust the torsion force of the first torsion spring according to actual requirements. The roller 48 and the second roller shaft are connected by the third micro-bearing, and snap rings and limit sleeves are provided at both ends of the roller to prevent the roller from moving axially on the shaft. A photoelectric switch BB and a photoelectric switch CC are provided in this assembly, which are the switches of the second driving motor 24. When the positioning piece rotates counterclockwise to the position of the photoelectric switch CC, the second driving motor starts, and when the positioning piece rotates clockwise to the position of the photoelectric switch BB, the second driving motor stops.

[0033] The main feature of the paper tape tensioning mechanism is that when the paper tape driving mechanism 5 receives the driving signal sent by the microprocessor on the circuit board, the driving motor 20 starts to feed the paper tape for feeding. The fed paper tape, under the tension of the first torsion spring 33, causes the roller assembly 30 and the positioning piece 31 fixed on the swing rod 32 to swing to the left together, keeping the paper tape always in a tensioned state. When the positioning piece 31 swings to the position of the photoelectric switch C (seeFigure 5 ), the microprocessor sends a start signal to the second driving motor 24, and the second driving motor rotates counterclockwise to wind the paper tape released during feeding into the second rubber disk until the positioning piece 31 swings to the position of the photoelectric switch B (see Figure 4 ), the microprocessor sends a stop signal to the second driving motor; Another feature of this mechanism is that a fan-shaped slot hole DD is opened on the total mounting bracket 2, so that the first roller shaft 50 can swing left and right in the fan-shaped slot hole D. The third feature is that the roller 48 is connected to the first roller shaft 50 through the third micro-bearing 47, and the swing rod 32 is also connected to the rotating shaft 35 through the second micro-bearing 34, and its rotational resistance is very small, see Figure 2 .

[0034] The paper tape driving mechanism 5 is mainly composed of a paper tape pressing device 12, a first locking nut 13, a first fixing rod 14, a first motor fixing plate 15, a photoelectric switch bracket 16, a driving shaft 17, a positioning disk 18, a positioning disk fixing sleeve 19, a first driving motor 20, a first micro-bearing 21, a first micro-bearing fixing sleeve 22, and a first snap ring 23, see Figure 6 . The main function of the paper tape driving mechanism 5 is to drive and pull the paper tape to feed through the first driving motor 20, so as to drive the material tape to unwind. The paper tape pressing device 12, on the one hand, plays the role of pressing the paper tape 4, and on the other hand, plays the role of transmitting force to push the paper tape forward. The first micro-bearing fixing sleeve 22 is fixed on the total mounting bracket 2 by the first locking nut 13, and the first motor fixing plate 15 is indirectly fixed on the total mounting bracket by the first fixing rod 14 through fasteners. The driving shaft 17 is sleeved on the shaft of the first driving motor by a set screw and is connected to the first micro-bearing fixing sleeve through the first micro-bearing. A positioning disk fixing sleeve 19 is also provided at one end of the driving shaft, and the positioning disk is fixed on the positioning disk fixing sleeve. When the first driving motor starts, the driving shaft, the positioning disk fixing sleeve, the positioning disk and the shaft of the first driving motor rotate together. The first driving motor and the photoelectric switch AA bracket are both fixed on the first motor fixing plate. The photoelectric switch AA is installed on the photoelectric switch bracket, and its emitting end and receiving end are respectively on both sides of the positioning disk, used to count the number of times the slit E on the positioning disk passes through the photoelectric switch AA. The slit E of the positioning disk is as Figure 10 shown, the paper tape pressing device is mainly composed of a second snap ring 37, a rubber roller 38, a connecting piece 39, a third micro-bearing 40, a second locking nut 41, a second locking screw 42, a double torsion spring 43, a torsion spring shaft 44, and a rubber roller shaft 45, see Figure 7。The torsion spring shaft 44 is fixed to the mounting bracket assembly 2 with the lock nut II 41. The torsion spring shaft passes through the center of the double torsion spring and the mounting round hole at one end of the connecting member 39. Both sides of the double torsion spring are fastened to the torsion spring shaft with lock screws. The other end of the pressing plate is penetrated with a rubber roller shaft 45, on which a rubber roller, a miniature bearing III and a snap ring II are mounted. The relational expression among the diameter D of the drive shaft, the number M of the slits on the positioning disk, the pitch P of the strip material and the set value N of the periodic increment of the photoelectric switch F is D = NP / π (assuming M = N). According to the actual situation, for the convenience of calculation, M can be designed as 2 n N (n is an integer), then D = NP / 2 n π. However, no matter what value M is set to, every time the positioning disk rotates through one slit, the paper tape will feed a length equal to one pitch of the strip material.

[0035] The main feature of the paper tape drive mechanism 5 is that it receives the step count signal from the photoelectric switch F. When the step count increment reaches a set value N (a positive integer), the drive motor I 20 starts once (every N steps form a cycle, and the drive motor starts once per cycle) to complete the feeding action of the paper tape 4. Assuming the pitch of the strip material is P, when the paper tape completes a feeding length of NP in one cycle, the drive motor I stops moving and waits for the count increment signal of the next cycle. The feeding principle of the paper tape 4 is as follows: Since a part of the rubber roller 38 presses on the paper tape 4 and another part presses on the drive shaft 17, when the drive motor I starts, the drive shaft 17 rotates to drive the rubber roller 38 to rotate, and the rotation of the rubber roller drives the paper tape 4 to feed, and there is no relative sliding between the drive shaft, the rubber roller and the paper tape; the positioning disk 18 is rigidly connected to the drive shaft 17 and rotates synchronously with the drive shaft; M slits E are equally spaced on the positioning disk. When the drive motor I starts, every time it rotates through one slit, the paper tape feeds a length equal to one pitch of the strip material; the photoelectric switch AA is used to detect the number of times the slit on the disk passes through the photoelectric switch. If the diameter of the drive shaft I at the position of the paper tape is D and M = N is assumed, according to the length of the strip material entering the automatic machine being equal to the feeding length of the paper tape, then NP = πD. Given N and P, D = NP / π can be obtained.

[0036] The paper tape recycling assembly mainly consists of a drive motor II 24, a motor fixing plate II 25, a rotating shaft II 26, a fixing rod II 27, a rubber disk II 28 and a locking device II 29. The locking device II is used to lock the rubber disk II, as shown in Figure 8 。The main function of this assembly is to recycle and wind the paper tape fed by the aforementioned paper tape feeding mechanism into the rubber disk II 28 exactly without excess or shortage.

[0037] During the paper tape feeding process, the positioning piece 31 swings to the left. When it swings to the position of the photoelectric switch CC, the microprocessor sends a start signal to the driving motor two 24, driving the glue disk two 28 to rotate counterclockwise, and winding the paper tape released during the paper tape feeding into the glue disk two, achieving the effect of paper tape recycling. At the same time, the positioning piece swings to the right. When the positioning piece swings to the right to the position of the photoelectric switch BB and receives the stop signal from the microprocessor, the driving motor two stops rotating.

[0038] The paper tape guiding assembly 6, as Figure 9 shown, is mainly composed of a circlip three 46, a miniature bearing three 47, a roller 48, a limit sleeve 49, and a roller shaft one 50. The main function of this assembly is to change the direction of the paper tape so that the paper tape enters the paper tape driving mechanism horizontally.

[0039] As Figure 11 shown, the tape reel assembly 8 is mainly composed of a rotating shaft one 9, a glue disk one 10, and a locking device one 11. A tape 1 containing parts to be packaged or reprocessed and a paper tape 4 for isolation and protection are wound in the glue disk 10. The tape enters the automatic machine, and the paper tape is recycled and wound into the glue disk two 28. Before the tape enters the automatic machine, it needs to pass through the photoelectric switch FF for counting, and the counting signal is transmitted to the microprocessor in real time for the next action.

[0052] Such as Figure 12 , after the system is powered on, first perform an initial position self-check. When the first drive motor starts, the positioning disk rotates counterclockwise until the nearest slit on the disk reaches the position of the photoelectric switch. Then the second drive motor starts, and the positioning piece rotates clockwise until it reaches the position of photoelectric switch B. After the self-check is completed, the photoelectric switch F performs step counting until the incremental set value N. Then the first drive motor starts, and the positioning piece swings counterclockwise. Determine whether it reaches the position of photoelectric switch C. If not, return to the step of the photoelectric switch F performing step counting until the incremental set value N. If so, the second drive motor starts, and when the positioning piece swings clockwise to the position of photoelectric switch B, the second drive motor stops. While the positioning piece swings counterclockwise, when the photoelectric switch A passes through the N slits on the positioning disk, the first drive motor stops. Determine whether to continue. If not, press the exit key to end. If so, return to the step of the photoelectric switch F performing step counting until the incremental set value N.

7. The usage method of a feeding drive device for a material tape and a paper tape with equal length as described in any one of claims 1 - 6, characterized in that: The following steps are involved: The paper tape is pulled through the paper tape driving mechanism and the paper tape tensioning mechanism in sequence and is wound around the paper tape recovery component. The material tape is discharged through the photoelectric switch F for counting, and the counting signal is transmitted to the microprocessor in real time. When the paper tape driving mechanism receives the driving signal from the microprocessor, the driving motor starts to feed the paper tape and discharge the material, so that the paper tape is always in a tensioned state. The paper tape driving mechanism receives the counting signal from the photoelectric switch F. When the counting increment reaches a set value N, the paper tape driving mechanism starts once to complete the feeding action of the paper tape. The step length of the material tape is set to P. When the paper tape completes a feeding length NP of a cycle, the paper tape driving mechanism stops moving and waits for the counting increment signal of the next cycle. During the paper tape feeding process, the microprocessor sends a starting signal to the paper tape recovery component to reel in the paper tape released during the paper tape feeding.
