[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] Figure 1 A schematic diagram of the PCB LED strip automatic assembly machine structure in an embodiment of the present invention is shown. Figure 2 A schematic diagram of the PCB light strip feeding mechanism in an embodiment of the present invention is shown. The automatic PCB light strip assembly machine includes: a PCB light strip feeding mechanism 4 for feeding and conveying PCB light strips 5; a material handling mechanism 2 for transporting the carrier 6 and the PCB light strips 5; a carrier feeding mechanism 3 for feeding and conveying the carrier 6; and a loading platform 1 for fixing the carrier 6 and the PCB light strips 5. The material handling mechanism 2 includes a carrier gripping device 26 and a PCB light strip 5 adsorption part.

[0052] The carrier gripping device 26 includes a first clamping part and a second clamping part, which are symmetrically distributed on the material handling mechanism 2.

[0053] The PCB light strip 5 adsorption part includes a set of movable adsorption parts 28 and several sets of fixed adsorption parts 27. The movable adsorption parts 28 are disposed at one end of the material picking mechanism 2, and the several sets of fixed adsorption parts 27 are arranged on the material picking mechanism 2 at a preset interval.

[0054] The movable adsorption part 28 is used to drive the PCB light strip 5 to move;

[0055] The loading platform 1 is provided with a positioning plate 11, which is used to support the carrier 6. The carrier 6 is provided with a plurality of light strip slots, and a locking mechanism is provided on the light strip slots. The PCB light strip 5 is set on the light strip slot based on the locking mechanism.

[0056] Specifically, the PCB light strip loading mechanism 4, the carrier loading mechanism 3, and the loading platform 1 are arranged in parallel along the X-axis. The picking mechanism 2 is located above the PCB light strip loading mechanism 4, the carrier loading mechanism 3, and the loading platform 1. The picking mechanism 2 can move along the X-axis and the Y-axis, which facilitates the picking mechanism 2 to pick up the carrier 6 and the PCB light strip 5 from the carrier loading mechanism 3 and the PCB light strip loading mechanism 4 and transport them to the loading platform 1.

[0057] Furthermore, the loading platform 1 is positioned between the carrier loading mechanism 3 and the PCB light strip loading mechanism 4, so that the operations of the material handling mechanism 2 in transporting the carrier 6 and transporting the PCB light strip 5 can be independent of each other, avoiding the carrier 6 or PCB light strip 5 from falling off during the transport process and affecting other equipment.

[0058] Specifically, Figure 3 The diagram shows a rear view of the PCB light strip feeding mechanism in an embodiment of the present invention. The PCB light strip feeding mechanism 4 includes a PCB light strip hopper 41, a lifting plate 43, a first lifting screw assembly 42, and a first driving component 44. The PCB light strip hopper 41 is provided with a hopper groove, and a plurality of PCB light strips 5 are placed in the hopper groove, with the plurality of PCB light strips 5 stacked in the hopper groove.

[0059] Furthermore, the PCB light strip hopper 41 can be provided with a number of hopper slots, thereby enabling the simultaneous supply of multiple PCB light strips 5.

[0060] Specifically, the lifting plate 43 is located below the PCB light strip hopper 41. The lifting plate 43 is mounted on the first lifting screw assembly 42 and moves up and down along the Y-axis based on the first lifting screw assembly 42. The lifting plate 43 is provided with a plurality of lifting slots. The plurality of lifting slots are located below the hopper hopper and are connected to the PCB light strip 5 at the bottom of the hopper hopper. When the lifting plate 43 moves up and down with the first lifting screw assembly 42, it can lift the PCB light strip 5 in the hopper hopper through the plurality of lifting slots.

[0061] Furthermore, the lifting slot pieces are distributed at preset intervals, so that the lifting plate 43 can keep the PCB light strip 5 stable when lifting the PCB light strip 5, and reduce the contact stress between the lifting plate 43 and the PCB light strip 5, thereby avoiding damage to the PCB light strip 5 during the lifting process.

The first driving member 44 drives the first lifting screw 421 to rotate through the transmission belt.

[0063] Furthermore, a second transmission wheel 426 is provided at the top of the second lifting screw 422. The first transmission wheel 425 and the second transmission wheel 426 are connected by a second transmission belt 427. When the first driving member 44 drives the first lifting screw 421 to rotate, the second lifting screw 422 can be driven to rotate synchronously through the second transmission belt 427. Specifically, Figure 4 A schematic diagram of the carrier loading mechanism in an embodiment of the present invention is shown. The carrier loading mechanism 3 includes a lifting plate 33, a second lifting screw assembly 32, and a second drive member 31. The lifting plate 33 is disposed on the second lifting screw assembly 32. The output end of the second drive member 31 is connected to the second lifting screw assembly 32. The lifting plate 33 is used to carry a plurality of carriers 6, and the plurality of carriers 6 are stacked on the lifting plate 33.

[0064] Furthermore, the second lifting screw assembly 32 has the same structural features and functional effects as the first lifting screw assembly 42. For details, please refer to the structural features and functional effects of the first lifting screw assembly 42, which will not be elaborated here.

[0065] Specifically, the working process of the carrier loading mechanism 3 is as follows: after the material taking mechanism 2 completes a material taking operation of the carrier 6 on the carrier loading mechanism 3, the second driving component 31 drives the second lifting component to rotate, thereby driving the lifting plate 33 to lift the carrier 6 by a preset distance for material feeding.

[0066] Furthermore, after all the carriers 6 on the lifting platform 33 have been moved, the second drive unit 31 drives the lifting platform 33 to descend to the bottom position, waiting for the operator to load the carriers 6.

[0067] Furthermore, the first driving component 44 and the second driving component 31 can be a drive motor or a drive cylinder 281, thereby enabling the lifting and feeding of the PCB light strip 5 in coordination with the assembly efficiency of the PCB light strip 5.

[0068] Specifically, Figure 5 A schematic diagram of the material handling mechanism in an embodiment of the present invention is shown. The material handling mechanism 2 includes a transplanting mechanism, a support frame 24, a material handling plate 25, and a lifting motor 21.

The left slide rail assembly 22 is slidably connected to one side of the support frame 24, and the right slide rail assembly 23 is slidably connected to the other side of the support frame 24.

[0069] Specifically, the left slide rail assembly 22 is provided with a left slide rail, a left transmission pulley and a connecting block. A left connecting plate 29 is provided on one side of the support frame 24. The left connecting plate 29 is fixed on the mating slider of the left slide rail. The support frame 24 can move on the left slide rail based on the left connecting plate 29 and the mating slider. One end of the connecting block is provided on the transmission pulley and the other end of the connecting block is fixed on the left connecting plate 29.

[0070] Furthermore, the connecting block can move along the X-axis based on the rotation of the left transmission pulley, and the left transmission pulley can drive the left connecting plate 29 to move along the left slide rail based on the connecting block, thereby driving the support frame 24 to move along the X-axis.

[0071] Furthermore, the right slide rail assembly 23 is provided with a right slide rail and a right transmission pulley, and a right connecting plate is provided on one side of the support frame 24. One side of the support frame 24 is based on the right connecting plate and cooperates with the sliding block of the right slide rail. The structural connection relationship of the right slide rail assembly is the same as that of the left slide rail assembly. For details, please refer to the structural connection relationship of the left slide rail assembly described above. It will not be repeated here.

[0072] Furthermore, the transplanting mechanism is positioned above the PCB light strip feeding mechanism 4, the carrier feeding mechanism 3, and the loading platform 1. The support frame 24 can move to the position above the PCB light strip feeding mechanism 4, the carrier feeding mechanism 3, and the loading platform 1 based on the transplanting mechanism, so as to meet the material picking and handling operations of the PCB light strip 5 and the carrier 6 of the picking mechanism 2. By setting the left slide rail assembly and the right slide rail assembly, the structural stability of the transplanting mechanism is improved, thereby improving the reliability of the material picking and handling of the transplanting mechanism.

[0073] Specifically, the material handling carrier plate 25 is an L-shaped structural plate, which includes a main carrier plate located in the XZ plane and a connecting carrier plate located in the YZ plane. A plurality of reinforcing ribs 251 are provided between the main carrier plate and the connecting carrier plate. The plurality of reinforcing ribs 251 are used to improve the stability of the connection structure between the main carrier plate and the connecting carrier plate, and to improve the overall rigidity of the material handling carrier plate 25, so as to meet the clamping and handling requirements of the PCB light strip 5 and the carrier 6.

[0074] Furthermore, the support frame 24 is provided with a slide rail assembly 241, and the connecting plate is disposed on the matching slider of the slide rail assembly 241, thereby enabling it to move up and down along the slide rail assembly 241 in the Y-axis direction.

[0075] Furthermore, multiple slide rail assemblies 241 can be provided on the support frame 24. The multiple slide rail assemblies 241 are evenly distributed on the support frame 24 to improve the connection structure stability of the material picking carrier plate 25 and ensure that the material picking carrier plate 25 can move smoothly on the support frame 24.

[0076] Furthermore, the lifting motor 21 is fixed in the middle of the support frame 24, and the output end of the lifting motor 21 is connected to the reinforcing rib plate 251 in the middle of the material picking carrier plate 25. The lifting motor 21 is used to drive the material picking carrier plate 25 to move up and down along the Y axis, thereby meeting the operation requirements of picking, transporting and releasing PCB light strip 5 and carrier 6.

[0077] Specifically, the material handling mechanism 2 is provided with a plurality of carrier gripping devices 26 and a plurality of PCB light strip 5 adsorption parts. The plurality of carrier gripping devices 26 are evenly arranged on the material handling carrier plate 25. The plurality of carrier gripping devices 26 are used to clamp and transport the carrier 6, and the plurality of PCB light strip 5 adsorption parts are used to adsorb and transport the PCB light strip 5.

[0078] Specifically, the carrier gripping device 26 includes a gripper cylinder, a first gripper, and a second gripper. The gripper cylinder is located at the central axis of the material handling plate 25. One end of the first gripper extends outside one side of the material handling plate 25, and the other end is connected to the output end of the gripper cylinder. One end of the second gripper extends outside the other side of the material handling plate 25, and the other end is connected to the output end of the gripper cylinder. The gripper cylinder is used to drive the first gripper and the second gripper to move.

[0079] Furthermore, the output end of the gripper cylinder is provided with a first moving block and a second moving block. The gripper cylinder can drive the first moving block and the second moving block to move towards each other or away from each other. One end of the first gripper is provided on the first moving block, and one end of the second gripper is provided on the second moving block. The gripper cylinder can drive the first gripper and the second gripper to move towards each other or away from each other, thereby realizing the release of the gripper of the carrier 6.

[0080] Specifically, a clamping mating plate is provided at one end of the first gripper extending outside the material handling plate 25. The clamping mating plate is provided with a mating groove. When clamping the carrier 6, one side of the carrier 6 can be engaged in the mating groove, thereby improving the stability of the mating connection between the first gripper and the carrier 6 and improving the reliability of the first gripper in handling the carrier 6.

[0081] Furthermore, a guide block is also provided on the first gripper, which is used to restrict the movement direction of the first gripper.

[0083] Specifically, the plurality of PCB light strip 5 adsorption parts include a plurality of fixed adsorption parts 27 and at least one movable adsorption part 28. The plurality of PCB light strip 5 adsorption parts are arranged on the material pick-up carrier 25 at a preset interval, wherein the movable adsorption part 28 is disposed at one end of the material pick-up carrier 25.

[0084] Furthermore, each of the PCB light strip 5 adsorption parts is provided with a plurality of suction nozzles, which are evenly arranged along the X-axis direction, and each of the suction nozzles corresponds one-to-one with the material hopper in the PCB light strip feeding mechanism 4, so as to perform adsorption operations on multiple PCB light strips 5 simultaneously.

[0085] Specifically, each of the suction nozzles includes a suction cup rod and a vacuum suction cup. The material carrier plate 25 is provided with several through slots at the installation position of the PCB light strip 5 adsorption part. Several suction cup rods are inserted into the through slots. One end of the suction cup rod extends through the through slot to the bottom of the material carrier plate 25. The vacuum suction cup is disposed on one end of the suction cup rod and is used to adsorb the PCB light strip 5 on the PCB light strip feeding mechanism 4. The other end of the suction cup rod is connected to an external air source through a connecting pipe, thereby controlling the suction and release of the vacuum suction cup.

[0086] Furthermore, a spring is provided inside the suction cup rod. When the PCB light strip 5 is adsorbed by the suction part of the PCB light strip 5, the suction cup rod can reduce the squeezing force on the PCB light strip 5 through the spring, thereby reducing the risk of the PCB light strip 5 being damaged by pressure.

[0087] Specifically, the fixed adsorption part 27 includes a mounting plate, which is fixed at the positions of several through slots. The mounting plate is used to support several suction nozzles, so that the suction nozzles can move up and down with the material pick-up carrier 25 to adsorb and transport the PCB light strip 5.

[0088] Specifically, Figure 6 A schematic diagram of the movable adsorption unit structure in an embodiment of the present invention is shown. The movable adsorption unit 28 includes a driving cylinder 281, a top block 282, and a mounting movable plate 283. One end of the material picking carrier plate 25 is provided with a slide rail along the Z-axis. The mounting movable plate 283 is disposed on a matching slider of the slide rail, that is, the mounting movable plate 283 can move along the slide rail along the Z-axis with the matching slider. The mounting movable plate 283 is used to support the suction nozzle inside the movable adsorption unit 28.

[0089] Furthermore, the output end of the drive cylinder 281 is connected to one end of the top block 282, and the other end of the top block 282 is connected to the mounting movable plate 283. The drive cylinder 281 can drive the top block 282 to move along the Z-axis, thereby pushing the mounting movable plate 283 to move along the Z-axis.

[0090] Furthermore, the movable adsorption part 28 is also provided with a limiting plate 284, which is used to limit the moving distance of the mounting movable plate 283, so as to prevent the mounting movable plate 283 from causing the PCB light strip 5 to exceed the moving limit range and thus damage the PCB light strip 5.

[0091] Specifically, the PCB light strip 5 is transported and loaded as follows: the picking mechanism 2 picks up the PCB light strip 5 from the PCB light strip loading mechanism 4 through the fixed adsorption part 28 and several movable adsorption parts 27, transports the PCB light strip 5 to the top of the loading platform 1, and drives the picking mechanism 2 to descend through the lifting motor 21, so that the PCB light strip 5 cooperates with the light strip slot of the carrier 6 on the loading platform 1.

[0092] Furthermore, by releasing the adsorption of the PCB light strip 5 by several fixed adsorption parts 27, and driving the material handling mechanism 2 to rise by the lifting motor 21, one end of the PCB light strip 5 is lifted by the movable adsorption part 28. The PCB light strip 5 is then driven to move in the Z-axis direction by the driving cylinder 281, so that one end of the PCB light strip 5 is aligned with one end of the carrier 6. The lifting motor 21 drives the material handling mechanism 2 to descend, so that the fixed adsorption parts 27 are in contact with the PCB light strip 5. The fixed adsorption parts 27 and the movable adsorption parts 28 press the PCB light strip 5 into the light strip groove of the carrier 6 and lock it based on the locking mechanism of the carrier 6. The movable adsorption parts 28 release the adsorption of the PCB light strip 5, and the lifting motor 21 drives the material handling mechanism 2 to rise, completing the material handling and loading operation of the PCB light strip 5.

[0093] Specifically, Figure 7 A schematic diagram of the loading platform structure in an embodiment of the present invention is shown. Figure 8 A schematic diagram of the bottom structure of the loading platform in an embodiment of the present invention is shown. The loading platform 1 includes a Z-axis conveying device 12 and a lifting loading device. The Z-axis conveying device 12 includes a first conveyor pulley assembly 121 and a second conveyor pulley assembly 122. The first conveyor pulley assembly 121 and the second conveyor pulley assembly 122 are respectively disposed on both sides of the support frame.

[0094] Specifically, the Z-axis conveying device 12 further includes a conveying drive motor. The first conveyor pulley assembly 121 includes a first conveyor belt, a driving pulley, and a driven pulley. The driving pulley and the driven pulley are linked based on the first conveyor belt. The output end of the conveying drive motor is connected to the driving pulley. The conveying drive motor is used to drive the first conveyor pulley assembly 121 to rotate.

[0095] Furthermore, the second conveyor pulley assembly 122 is provided with the same conveying structure as the first conveyor pulley assembly 121, and the driven pulley of the first conveyor pulley assembly 121 is connected to the second conveyor pulley assembly 122 based on the rotating connecting shaft. When the conveying drive motor drives the first conveyor pulley assembly 121 to rotate, the first conveyor pulley assembly 121 can drive the second conveyor pulley assembly 122 to rotate synchronously based on the rotating connecting shaft.

[0096] Specifically, the carrier 6 is provided with a plurality of light strip slots, and each of the light strip slots is provided with a locking mechanism. The PCB light strip 5 is mounted on the light strip slot based on the locking mechanism. The light strip slot is provided with a plurality of mounting areas, each mounting area including a positioning slot on the top surface of the light strip slot and a mating slot on the bottom surface of the light strip slot. The positioning slot and the mating slot are staggered and connected to each other.

[0097] Specifically, Figure 9 A cross-sectional view of the locking mechanism structure in an embodiment of the present invention is shown. The locking mechanism includes a locking block 7 and a locking spring 71. The locking block 7 is a Z-shaped structure. One end of the Z-shaped structure is located in the slot and the other end is located in the mating slot. The Z-shaped structure is held in a locked state based on the locking spring 71.

[0098] Specifically, the lifting and loading device includes a positioning plate 11, on which a plurality of positioning pins are provided. The other end of the locking block 7 is provided with a mating hole 72, into which the positioning pins are inserted. When the material handling mechanism 2 transports the carrier 6 onto the positioning plate 11 of the lifting and loading device, the carrier 6 is positioned precisely on the positioning plate 11 by correspondingly engaging the mating hole 72 of the locking block 7 with the positioning pins.

[0099] Furthermore, the loading platform 1 is also provided with a push block baffle 13 and a push block cylinder 16. The push block cylinder 16 is located at the lower end of the positioning plate 11, and the output end of the push block cylinder 16 is connected to the push block baffle 13. The push block baffle 13 is located outside one side of the loading platform 1. When the carrier 6 is located on the positioning plate 11, the push block cylinder 16 can drive the push block baffle to retract and move, thereby pushing the carrier 6 on the positioning plate 11 to move. The locking block 7 remains stationary under the action of the positioning pin. The carrier 6 and the locking block 7 move relative to each other, so that the locking spring 71 on the locking block 7 is in a compressed state. The Z-shaped structural component is in an open state based on the compression of the locking spring 71, so that the PCB light strip 5 can be placed on the carrier 6.

[0100] Furthermore, after the PCB light strip 5 and the carrier 6 are engaged, the push block cylinder 16 drives the push block baffle 13 to reset, and the locking mechanism can elastically return based on the locking spring 71, thereby resetting the carrier 6. The locking mechanism is in a locked state and locks the PCB light strip 5 onto the carrier 6.

[0101] Specifically, the lifting loading device further includes a lifting cylinder 17, a lifting bracket 19, and a lifting support shaft 18. The lifting cylinder 17 is mounted on the lifting bracket 19. The lifting bracket 19 is connected to the bottom of the positioning plate 11 based on two symmetrically distributed lifting support shafts 18. The lifting support shaft 18 is a telescopic shaft structure. When the lifting cylinder 17 drives the positioning plate 11 to descend, the lifting support shaft 18 can retract and support the positioning plate 11, ensuring the structural stability of the loading platform 1.

[0102] Specifically, the lifting cylinder 17 is connected to the positioning plate 11. The lifting cylinder 17 is used to drive the positioning plate 11 to move up and down. When the PCB light strip 5 is locked on the carrier 6, the lifting cylinder 17 drives the positioning plate 11 to descend. The carrier 6 descends accordingly and is supported on the Z-axis conveying device 12. The descent of the positioning plate 11 causes the positioning pin to disengage from the carrier 6. After the lifting cylinder 17 completes the descent operation of the fixed plate, the Z-axis conveying device 12 starts to work, driving the carrier 6 and the PCB light strip 5 to be conveyed out.

[0103] This invention provides an automatic assembly machine for PCB light strips 5. The automatic assembly machine for PCB light strips 5 uses a material picking mechanism 2 to pick up the carrier 6 and the PCB light strips 5 and transport them to the loading platform 1. The movable adsorption part 28 drives the PCB light strips 5 to automatically align on the carrier 6 and locks them synchronously through a locking mechanism, thereby improving the assembly efficiency and assembly effect of the PCB light strips 5.

[0104] Example 2:

[0105] Figure 10 This diagram illustrates a flowchart of an automatic PCB LED strip assembly machine according to an embodiment of the present invention. The assembly method is used to assemble a PCB LED strip 5 onto a carrier 6. The carrier 6 is equipped with a locking mechanism, and the PCB LED strip 5 is locked onto the carrier 6 based on the locking mechanism. The assembly method includes the following steps:

[0106] S11: The drive mechanism 2 picks up the carrier 6 on the carrier loading mechanism 3 and transports the carrier 6 to the positioning plate 11 of the loading platform 1. Specifically, the PCB light strip automatic assembly machine is equipped with a control host. The control host drives the pick-up mechanism 2 to move above the carrier loading mechanism 3, and drives the pick-up carrier plate 25 of the pick-up mechanism 2 to descend through the lifting motor 21, so that the carrier 6 of the carrier loading mechanism 3 is within the clamping range of the carrier gripping device 26. The gripper cylinder drives the first gripper and the second gripper to move towards each other, so that the first gripper and the second gripper clamp the carrier 6.

[0107] Specifically, the carrier loading device is equipped with a pressure sensor, which is connected to the control host. The pressure sensor is used to detect the storage status of the carriers 6 on the lifting platform 33. By detecting the pressure value on the lifting platform 33, the storage status of the carriers 6 on the lifting platform 33 is determined based on the pressure value. When the pressure value on the lifting platform 33 is lower than the preset pressure value, the pressure sensor feeds back to the control host. The control host controls the carrier loading mechanism 3 to issue a warning and notify the operator to replenish the carriers 6.

[0108] Specifically, the carrier 6 is provided with a plurality of light strip slots, each of which is provided with a locking mechanism. The positioning plate 11 is provided with a plurality of positioning pins. The carrier 6 is transported onto the positioning plate 11, and the locking mechanism on the carrier 6 is correspondingly set on the positioning pins of the positioning plate 11.

[0109] S12: Push the carrier 6 on the positioning plate 11 by pushing the push block baffle 13 to open the locking mechanism on the carrier 6.

[0110] Specifically, when the carrier 6 is engaged with the positioning plate 11 based on the positioning pin on the positioning plate 11, the control host controls the push block cylinder 16 to work, and the push block baffle 13 is driven to retract by the push block cylinder 16. The push block baffle 13 can push the carrier 6 to move, and the locking mechanism on the carrier 6 is opened based on the positioning pin on the positioning plate 11 so as to perform the assembly operation of the PCB light strip 5.

[0111] S13: Drive the material handling mechanism 2 to pick up the PCB light strip 5 from the PCB light strip feeding mechanism 4 and transport the PCB light strip 5 into the light strip slot on the carrier 6.

[0112] Specifically, the control host drives the transfer mechanism of the material picking mechanism 2 to move the material picking mechanism 2 above the PCB light strip loading mechanism 4. The lifting motor 21 drives the material picking carrier plate 25 to descend, so that the fixed adsorption part 27 and the movable adsorption part 28 on the material picking carrier plate 25 come into contact with the PCB light strip 5 of the PCB light strip loading mechanism 4. The fixed adsorption part 27 and the movable adsorption part 28 on the material picking mechanism 2 adsorb the PCB light strip 5 on the PCB light strip loading mechanism 4.

[0113] Furthermore, the material handling mechanism 2 transports the adsorbed PCB light strip 5 to the top of the carrier 6, and the control host drives the lifting motor 21 to work, which drives the material handling carrier plate 25 to descend, so that the PCB light strip 5 is correspondingly matched in the light strip groove of the carrier 6.

[0114] S14: Drive the active adsorption part 28 to adjust the position of the PCB light strip 5 on the carrier 6, and lock it in place by closing the locking mechanism.

[0115] Specifically, after the PCB light strip 5 is placed in the light strip slot of the carrier 6, the control host generates a PCB light strip adjustment command and sends it to the material picking mechanism 2. Based on the adjustment command, the material picking mechanism 2 releases the adsorption of the fixed adsorption part 27 on the PCB light strip 5, and drives the material picking carrier plate 25 to rise to a preset height through the lifting motor 21. At this time, the material picking carrier plate 25 is adsorbed and connected to one end of the PCB light strip 5 through the movable adsorption part 28. That is, one end of the PCB light strip 5 is lifted based on the rising operation of the material picking carrier plate 25. By driving the movable adsorption part 28 to move along the Z-axis, the PCB light strip 5 is moved on the light strip slot, so that multiple PCB light strips 5 are aligned at one end in the light strip slot of the carrier 6.

[0116] Furthermore, after the PCB light strips 5 on the carrier 6 are aligned, the control host drives the lifting motor 21 of the material picking mechanism 2 to work, causing the material picking carrier plate 25 to descend, so that the suction nozzles on the fixed suction part 27 and the movable suction part 28 come into contact with the PCB light strips 5, and the PCB light strips 5 are pressed into the light strip groove by the fixed suction part 27 and the movable suction part 28. The push plate is driven to reset by the push block cylinder 16, and the carrier 6 is reset based on the elasticity of the locking spring 71 of the locking mechanism, so that the locking mechanism returns to the locked state, locking the PCB light strips 5 into the light strip groove of the carrier 6.

[0117] Specifically, after the PCB light strip 5 is locked onto the carrier 6, the positioning plate 11 is driven to descend by the lifting cylinder, thereby disengaging the positioning pin on the positioning plate 11 from the locking mechanism of the carrier 6. The carrier 6 is then disengaged from the positioning plate 11, and the carrier 6 is supported on the Z-axis conveying device 12. The Z-axis conveying device 12 then transports the carrier 6 for the unloading operation.

[0118] This invention provides an automatic assembly method for PCB light strips 5. The assembly method involves a material handling mechanism 2 picking up a carrier 6 from a carrier loading mechanism 3 and transporting it to a loading platform 1. The material handling mechanism 2 then picks up a PCB light strip 5 from a PCB light strip loading mechanism 4 and transports it to the carrier 6 on the loading platform 1. The movable adsorption part 28 on the material handling mechanism 2 adjusts the position of the PCB light strip 5 on the carrier 6 to ensure alignment. Finally, a locking mechanism locks the PCB light strip 5 onto the carrier 6, effectively improving the assembly efficiency and effect of the PCB light strip 5 carrier 6.

Specific examples have been used to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
