Description

Technical Field

[0001] The present invention relates to the field of lamp bead packaging, and specifically discloses a taping machine and method for LED lamp bead production. Background Art

[0002] When patch-type LEDs are mass-produced, a light-splitting process and a taping process are required. Among them, the light-splitting process is to detect the performance parameters of the LEDs and classify the LEDs according to their luminous color temperature values. The taping process is to load the LEDs onto a carrier tape for roll packaging for easy transportation and sales. When in use, a whole roll of taping material needs to be unrolled first, then the lamp beads are taken out from the tape, and finally the lamp beads are pasted onto the bottom plate one by one by a mounter.

[0003] For example, the invention patent with the patent application number CN116902285B discloses a taping machine for LED lamp bead production, including an outer frame support, a door panel, a support guide plate, etc.; one side of the outer frame support is connected with a door panel through a hinge, the middle part of the inner wall of the outer frame support is fixedly connected with a support guide plate, the support guide plate passes through the top of the outer frame support, and a groove is opened on the upper side of the support guide plate to reduce the occurrence of wrinkles caused by the slack of the adhesive film, so that the adhesive film can be flat and stable and adhered to the lamp bead carrier tape and the patch lamp beads, so that the patch lamp beads can be more firmly adhered to the wound lamp bead carrier tape, facilitating the complete taping of the lamp bead carrier tape.

[0004] The existing taping machine only ensures that the lamp beads can be accurately attached to the lamp bead carrier tape to prevent the position of the lamp beads from shifting in the lamp bead carrier tape. However, when the lamp bead carrier tape and the adhesive film are used up, they need to be manually replaced. After the replacement is completed, the starting ends of the lamp bead carrier tape and the adhesive film need to be manually pulled to the taping machine by workers, and then the machine can be started. This will lead to an increase in time and labor costs. At the same time, when the starting ends of the materials are manually pulled to the taping machine by workers, the operators need to repeatedly adjust the position to align with the guiding inlet of the taping machine, resulting in the cutting and discarding of the ineffective traction section, which also causes waste of materials. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a taping machine and method for LED lamp bead production to solve the technical problems that when the lamp bead carrier tape and the adhesive film on the existing taping machine are used up, they need to be manually replaced. During the replacement process, due to the need for manual traction for feeding, this leads to an increase in labor costs and waste of raw materials, and also reduces the production efficiency of the taping machine.

[0006] To achieve the above object, the present invention provides the following technical solutions: a taping machine and method for producing LED lamp beads, including a base, a conveying table, two feeding mechanisms, a lamp bead carrier tape, a sticky film, a first robotic arm, a connecting mechanism, a heat sealing mechanism, and a winding mechanism. The conveying table is fixedly connected to the base. Two feeding mechanisms are also provided on the base. The lamp bead carrier tape and the sticky film are respectively arranged on the two feeding mechanisms. The lamp bead carrier is in contact with the conveying table, and the sticky film can be adhered to the lamp bead carrier tape. The first robotic arm is also provided on the base, and the first robotic arm is used for clamping the LED lamp beads and placing them into the lamp bead carrier tape. A connecting mechanism is also provided on the base, and the connecting mechanism is used for connecting two sets of the lamp bead carrier tapes. The heat sealing mechanism is arranged on the base, and the heat sealing mechanism is used for heat-sealing and connecting the sticky film. The winding mechanism is arranged on the base, and the winding mechanism is used for collecting the LED lamp bead tapes after the taping is completed. When it is necessary to package the LED lamp beads, start the first robotic arm on the base. The first robotic arm clamps and places the LED lamp beads into the lamp bead carrier tape. At this time, the winding mechanism drives the lamp bead carrier tape to move on the conveyor belt. When the lamp bead carrier tape is moving, the sticky film on the feeding mechanism will also adhere to the lamp bead carrier tape. When the lamp bead carrier tape on the feeding mechanism is used up, the starting end of another set of lamp bead carrier tape on the feeding mechanism is connected to the end of the lamp bead carrier tape that is about to be used up through the connecting mechanism, and then the lamp bead carrier tape can be used continuously. When the sticky film on the feeding mechanism is used up, the starting end of another set of sticky film on the feeding mechanism is connected to the end of the sticky film that is about to be used up through the heat sealing mechanism, and then the sticky film can be used continuously.

[0007] Further, both of the two feeding mechanisms include a first fixing plate, a first motor, a triangular turntable, and a feeding disk. The first fixing plate is fixedly connected to the base. The first motor is fixedly connected to the first fixing plate. The power output end of the first motor is fixedly connected to the triangular turntable. Feeding disks are arranged at the three corners of the triangular turntable, and the feeding disks are rotatably connected to the triangular turntable. When it is necessary to replace the lamp bead carrier tape, fix the end of the lamp bead carrier tape film on the feeding disk through the connecting mechanism. After fixing, drive the first motor on the first fixing plate. The first motor drives the triangular turntable to rotate. Since the feeding disks are arranged at the three corners of the triangular turntable, the just-used feeding disk is rotated to the other end at this time, and the unused feeding disk is rotated to the connecting mechanism. At this time, the connecting mechanism can connect the starting end of the unused lamp bead carrier tape to the end of the lamp bead carrier tape that was just fixed. When the sticky film needs to be replaced, only need to fix the end of the lamp bead carrier tape through the heat sealing mechanism, and then the triangular turntable rotates to move the unused sticky film to the heat sealing mechanism. At this time, the heat sealing mechanism fixes the starting end of the new sticky film to the end of the sticky film that was just fixed.

[0008] Further, the connecting mechanism includes a second fixing plate, a second robotic arm, a fixing needle, a first connecting plate, and a first inclined platform. The second fixing plate is fixedly connected to the base. The second robotic arm is fixedly connected to the second fixing plate. The fixing needle is arranged on the second robotic arm. One end of the first connecting plate is fixedly connected to the second fixing plate, and the other end is fixedly connected to the first inclined platform. The first inclined platform contacts the lamp bead carrier tape. When it is necessary to fixedly connect two groups of lamp bead carrier tapes, the lamp bead carrier tape is lifted by the first inclined platform on the first connecting plate, and then the second robotic arm on the second fixing plate drives the fixing needle to move. The starting end of the lamp bead carrier tape on the feeding tray is connected by the fixing needle. Since there are several fine needles on the fixing needle, the fixing needle is inserted into the starting end of the lamp bead carrier tape by the second robotic arm, and then the lamp bead carrier tape can be driven to move.

[0009] Further, the connecting mechanism further includes a first support block, a connecting device, a second support block, a second hydraulic rod, a first L-shaped rod, and a first limiting plate. The first support block is fixedly connected to the side wall of the first inclined platform. The connecting device is fixedly connected to the first support block and is used to connect two groups of the lamp bead carrier tapes. The second support block is fixedly connected to the side wall of the first inclined platform. The second hydraulic rod is fixedly connected to the second support block. The telescopic end of the second hydraulic rod is fixedly connected to the first L-shaped rod. The first limiting plate is fixedly connected to the first L-shaped rod and can be attached to the lamp bead carrier tape. When it is necessary to connect and fix the starting end of one group of lamp bead carrier tape and the end of another group of lamp bead carrier tape, the winding mechanism drives the lamp bead carrier tape to move. When the end of the lamp bead carrier tape moves to the end of the first inclined platform, the first L-shaped rod is driven to move by the second hydraulic rod on the second support block. The first L-shaped rod drives the first limiting plate to move. The end of the lamp bead carrier tape is pressed and fixed on the first inclined platform by the first limiting plate. At this time, the first limiting plate is not completely fixed at the end of the lamp bead carrier tape, leaving a distance for subsequent connection. When the lamp bead carrier tape is fixed on the first inclined platform by the first limiting plate, the triangular turntable drives the feeding tray to rotate, bringing the unused lamp bead carrier tape to the side close to the second robotic arm. Then, the starting end of the lamp bead carrier tape on the feeding tray is fixed by the fixing needle on the second robotic arm. After fixing, the starting end of the lamp bead carrier tape is pulled to the first inclined platform by the second robotic arm. Then, the two ends of the lamp bead carrier tape are aligned, and the connecting device on the first support block uses staples for connection and fixation. During the fixation process, the second robotic arm drives the fixing needle to be pulled out from the lamp bead carrier tape.

[0010] Further, the heat-sealing mechanism includes a third fixing plate, a third robotic arm, a suction cup, a second connecting plate, and a second inclined table. The third fixing plate is fixed on the base. The third robotic arm is fixedly connected to the third fixing plate. The suction cup is arranged on the third robotic arm. One end of the second connecting plate is fixedly connected to the third fixing plate, and the other end is fixedly connected to the second inclined table. The second inclined table contacts the adhesive film. The adhesive film is lifted by the second inclined table on the second connecting plate. Since the second inclined table is made of polyethylene, the second inclined table will not adhere to the adhesive film. When it is necessary to fix two groups of adhesive films, the third robotic arm on the third fixing plate drives the suction cup to move. The starting end of the adhesive film on the feeding tray is sucked by the suction cup, and then the starting end of the adhesive film is pulled to the second inclined table by the third robotic arm.

[0011] Further, the heat-sealing mechanism further includes a third hydraulic rod, a second L-shaped rod, a heat-sealing module, a fourth hydraulic rod, a third L-shaped rod, and a second limiting block. The third hydraulic rod is fixedly connected to the second connecting plate. The telescopic end of the third hydraulic rod is fixedly connected to the second L-shaped rod. The second L-shaped rod is fixedly connected to the heat-sealing module. The heat-sealing module is used to heat-seal and connect two groups of the adhesive films. The fourth hydraulic rod is fixedly connected to the second connecting plate. The telescopic end of the fourth hydraulic rod is fixedly connected to the third L-shaped rod. The third L-shaped rod is fixedly connected to the second limiting block. The second limiting block can be attached to the adhesive film. When it is necessary to heat-seal and connect two groups of adhesive films, when the coiling mechanism drives the bead carrier tape to move, it will also drive the adhesive film to move. When the end of the adhesive film moves to the end of the second inclined table, the fourth hydraulic rod drives the third L-shaped rod to move, and the third L-shaped rod drives the second limiting block to move. The end of the adhesive film is pressed and fixed on the second inclined table by the second limiting block. At this time, the second limiting block is not completely fixed at the end of the adhesive film, leaving a section for subsequent connection. At this time, the third robotic arm uses the suction cup to pull the starting end of the adhesive film on the feeding tray to the second inclined table to overlap with the end of the adhesive film fixed on the second inclined table. When the starting end and the end of the adhesive film coincide, the third hydraulic rod can drive the second L-shaped rod to move, and the second L-shaped rod drives the heat-sealing module to move to the overlapping part, and then starts heat-sealing connection. During the heat-sealing connection process, the third robotic arm drives the suction cup to pull out from the adhesive film.

[0012] Further, the winding mechanism includes a tractor, a winder, a fourth fixing plate, a support plate, two connecting rods, two limiting wheels, a support rod, a fifth hydraulic rod, and a rectangular cutting block. The tractor is fixedly connected to the base, the winder is fixedly connected to the side wall of the base, the fourth fixing plate is fixedly connected to the winder, the support plate is arranged on the fourth fixing plate, the support plate is attached to the lamp bead tape, two connecting rods are fixedly connected to the support plate, the two limiting wheels are rotatably arranged on the two connecting rods respectively, the support rod is fixedly connected to the winder, the fifth hydraulic rod is fixedly connected to the support rod, the telescopic end of the fifth hydraulic rod is fixedly connected to the rectangular cutting block, and the rectangular cutting block is located between the two limiting wheels. By rotating the tractor, the lamp bead tape can be driven to move on the transfer table, and then the encapsulated LED lamp bead tape can be collected by the winder. The support plate on the fourth fixing plate supports the lamp bead tape. The two limiting wheels on the two connecting rods limit the lamp bead tape and the adhesive film on the support plate, and also play a role in pressing the adhesive film and the lamp bead tape. When the winder is full and needs to replace the winding shaft, at this time, the fifth hydraulic rod on the support rod drives the rectangular cutting block to move. Through the cooperation of the tractor, the connection position of the previous lamp bead tape and the adhesive film is moved to the position of the rectangular cutting block, and then it is cut by the rectangular cutting block. At this time, the winding shaft on the winder can be replaced.

[0013] The working principle and beneficial effects of this solution are as follows:

[0014] When the lamp bead tape on the unwinding reel is about to be used up, the tractor reduces its rotation speed. When the end of the lamp bead tape on the unwinding reel moves to the first inclined platform, the tractor stops working. The first limiting plate fixes the end of the lamp bead tape on the first inclined platform. The position where the first limiting plate presses and fixes is still a certain distance from the end, providing a connection position for subsequent connection. The triangular turntable drives the unwinding reel to rotate to be close to the second robotic arm. The second robotic arm drives the fixing needle to move and insert into the starting end of the lamp bead tape on the unwinding reel, driving the starting end of the lamp bead tape to move to the first inclined platform and fit with the cross-section of the end of the lamp bead tape just fixed. The staple is used to fixedly connect the starting end and the end of the lamp bead tape through the connecting device. There is no need for manual operation to replace and feed the lamp bead tape. The second robotic arm drives the fixing needle to traction and fix the starting end of the lamp bead tape, reducing the labor cost expenditure and making the connection accuracy and repeatability consistent.

[0015] When the sticky film on the feeding tray is about to be used up, the connection sequence of the heat-sealing mechanism is the same as that of the connection mechanism. Only the starting end of the sticky film is fixed by a suction cup, and then overlaps with the end of the sticky film on the second inclined table and is heat-sealed and connected by a heat-sealing device. During the heat-sealing connection process, the third robotic arm drives the suction cup to pull off from the sticky film. Since the lamp bead carrier tape material is relatively thick, heat-sealing will cause problems with unstable connection. Using the staple connection of the connection device makes the connection more firm and stable. Since the sticky film is relatively thin, if staple connection is used, because only the two ends are connected by staples, the sticky film is prone to tearing during movement. Using heat-sealing not only improves the firmness between the sticky films, but also increases the contact area at both ends due to the overlap of the starting end and the end for heat-sealing, reducing the risk of tearing.

The second limiting block 36 can be attached to the adhesive film 5, as Figure 4 and Figure 5 shown.

[0030] The rewinding mechanism includes a tractor 37, a rewinder 38, a fourth fixing plate 43, a support plate 44, two connecting rods 45, two limiting wheels 46, a support rod 40, a fifth hydraulic rod 41 and a rectangular cutting block 42. The tractor 37 is fixedly connected to the base 1 and is used to tow the lamp bead carrier tape 4 and the adhesive film 5 after adhesion. The rewinder 38 is fixedly connected to the side wall of the base 1 and is used to wind the lamp bead carrier tape 4 and the adhesive film 5 after adhesion. The tractor 37 and the rewinder 38 are prior arts. The fourth fixing plate 43 is fixedly connected to the rewinder 38, and the fourth fixing plate 43 is fixedly connected with a support plate 44. The support plate 44 contacts the lamp bead carrier tape 4. One ends of the two connecting rods 45 are fixedly connected to the side wall of the support plate 44, and the other ends of the two connecting rods 45 are respectively rotatably provided with two limiting wheels 46. Both of the two limiting wheels 46 contact the adhesive film 5, and both of the two limiting wheels 46 can rotate on the adhesive film 5. The lamp bead carrier tape 4 and the adhesive film 5 are located between the two limiting wheels 46 and the support plate 44. One end of the support rod 40 is fixedly connected to the rewinder 38, and the other end is fixedly connected with a fifth hydraulic rod 41. The telescopic end of the fifth hydraulic rod 41 is fixedly connected with the rectangular cutting block 42. The rectangular cutting block 42 is located between the two limiting wheels. The rectangular cutting block 42 is U-shaped with sharp ends and can cut the adhesive film 5 and the lamp bead carrier tape 4, as Figure 6 and Figure 7 shown.

[0031] During specific implementation:

[0032] When it is necessary to put the LED lamp beads into the lamp bead carrier tape 4 for encapsulation through the adhesive film 5, the lamp beads are picked up by the first robotic arm 7 on the base 1, and then the LED lamp beads are put into the lamp bead carrier tape 4. At this time, the tractor 37 will drive the lamp bead carrier tape 4 to move on the transfer table 2. During the movement, the adhesive film 5 is pressed onto the lamp bead carrier tape 4 by the pressing roller 6 for encapsulation. At this time, the rewinder 38 collects the encapsulated lamp bead carrier tape 4.

[0033] When the lamp bead carrier tape 4 on the feeding tray 11 is about to be used up, the traction device 37 needs to reduce its rotation speed at this time. When the end of the lamp bead carrier tape 4 on the feeding tray 11 moves onto the first inclined platform 16, the traction device 37 stops working. At this time, the second hydraulic rod 22 on the second support block 23 is started, and the second hydraulic rod 22 drives the first L-shaped rod 24 to move. The first L-shaped rod 24 drives the first limiting plate 25 to fix the end of the lamp bead carrier tape 4 on the first inclined platform 16. At this time, there is still a certain distance from the position pressed and fixed by the first limiting plate 25 to the end, providing a connection position for subsequent connection. At this time, the connection of the lamp bead carrier tape 4 can be started. The first motor 9 on the first fixing plate 8 is started, and the first motor 9 drives the triangular turntable 10 to rotate. Since the three corners of the triangular turntable 10 are respectively provided with feeding trays 11, when the first motor 9 rotates, the unused feeding tray 11 is rotated to the position of the second robotic arm 13, and the used-up feeding tray 11 can be replaced manually. At this time, the second robotic arm 13 on the second fixing plate 12 is started, and the second robotic arm 13 drives the fixing needle 14 to move to the starting end of the lamp bead carrier tape 4 on the feeding tray 11. After the second robotic arm 13 inserts the fixing needle 14 into the starting end of the lamp bead carrier tape 4, it drives the starting end of the lamp bead carrier tape 4 to move onto the first inclined platform 16. When the lamp bead carrier tape 4 is moving, it will also not rotate on the triangular turntable 10, preventing the lamp bead carrier tape 4 from being pulled and broken. At this time, the second robotic arm 13 drives the starting end of the lamp bead carrier tape 4 to be in cross-section contact with the just-fixed end of the lamp bead carrier tape 4. After the contact, the stapler of the connecting device 17 is used to fixedly connect the starting end and the end of the lamp bead carrier tape 4. During the operation of the connecting device 17, the second robotic arm 13 drives the fixing needle 14 to be pulled out. After the connection, the lamp bead carrier tape 4 can continue to be used, eliminating the need for manual replacement and traction feeding operations of the lamp bead carrier tape 4. By driving the fixing needle 14 by the second robotic arm 13 to traction-fix the starting end of the lamp bead carrier tape 4, the labor cost expenditure is reduced, and the accuracy and repeatability are also kept consistent, avoiding the problem of unstable connection caused by human error.

[0034] When the sticky film 5 on the material feeding tray 11 is about to be used up, the rotation speed of the tractor 37 also needs to be reduced. When the sticky film 5 on the material feeding tray 11 moves to the second inclined platform 30, the tractor 37 stops working. The fourth hydraulic rod 34 on the second connecting plate 29 drives the third L-shaped rod to move, and the third L-shaped rod drives the second limiting block 36 to move. The end of the sticky film 5 is fixed on the second inclined platform 30 through the second limiting block 36. At this time, there is still a certain distance between the position fixed by the second limiting block 36 and the end of the sticky film 5, providing a heat-sealing position for the follow-up. At this time, the first motor 9 on the first fixing plate 8 can be started. The first motor 9 drives the triangular turntable 10 to rotate. Since the three corners of the triangular turntable 10 are respectively provided with material feeding trays 11, when the first motor 9 rotates, the unused one is rotated to the third robotic arm 27, and the used-up sticky film 5 is replaced manually. At this time, the third robotic arm 27 on the third fixing plate 26 is started, and the third robotic arm 27 drives the suction cup 28 to move to the starting end of the sticky film 5 on the transfer tray. The sticky film 5 is sucked through the suction cup 28. At this time, the suction cup 28 on the third robotic arm 27 drives the starting end of the sticky film 5 to move to the second inclined platform 30 and overlap with the end of the sticky film 5 fixed by the second limiting block 36 just now. At this time, the third hydraulic rod 31 drives the second L-shaped rod 32 to move, and the second L-shaped rod 32 drives the heat-sealing module 33 to move to the overlapping part of the starting end and the end of the sticky film 5 for heat-sealing connection. During the heat-sealing connection process, the third robotic arm 27 drives the suction cup 28 to pull out from the sticky film 5. After the heat-sealing is completed, the sticky film 5 can continue to cooperate with the lamp bead carrier tape 4 for use, without manual replacement and traction feeding. The third robotic arm 27 drives the suction cup 28 to overlap the starting end and the end of the sticky film 5, and the connection precision is also improved through the third robotic arm 27. Since the material of the lamp bead carrier tape 4 is relatively thick, heat-sealing may cause the problem of unstable connection. The stapling connection of the connecting device 17 is used to make the connection more firm. Since the sticky film 5 is relatively thin, if stapling connection is used, because only the two ends are connected by staples, the sticky film 5 is easily torn during the movement. Using heat-sealing not only improves the firmness between the sticky films 5, but also increases the contact area at both ends due to the overlap heat-sealing of the starting end and the end, reducing the risk of tearing.

[0035] When the winding wheel on the coiler 38 is full, stop the operation of the tractor 37, start the fifth hydraulic rod 41 on the support rod 40, and the fifth hydraulic rod 41 drives the rectangular cutting block 42 to cut off the adhesive film 5 and the lamp bead carrier tape 4. The support plate 44 plays a role in supporting the operation of the rectangular cutting block 42. The limiting wheels 46 on the two connecting rods 45 play a role in further pressing and fixing the lamp bead carrier tape 4 and the adhesive film 5, preventing the separation of the lamp bead carrier tape 4 and the adhesive film 5 after being cut by the rectangular cutting block 42. Since the rectangular cutting block 42 is U-shaped, during the cutting process of the rectangular cutting block 42, it can cooperate with the tractor 37 to drive the lamp bead carrier tape 4 and the adhesive film 5 to move, pulling the part where the starting end and the ending end of the previous lamp bead carrier tape 4 are stapled by the connecting device 17 to the position of the rectangular cutting block 42, and then cutting it off to reduce the impact on the later use.

[0036] The above are only embodiments of the present invention. Common knowledge such as specific structures and characteristics known in the solution is not described in detail here. It should be noted that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the present invention.
