[0054] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0055] To achieve flexible automated product assembly, the present invention provides an embodiment of a flexible production line, and specifically provides an embodiment of a mobile power bank production method implemented through this flexible production line embodiment.

[0056] like Figure 1-19 The diagram shown is a schematic representation of an embodiment of the flexible production line provided by the present invention.

[0057] Please refer to Figure 1-19 This embodiment includes a feeding assembly 10, a moving assembly 20, an assembly station 30, a recycling device 40, and a tooling plate 50. The tooling plate 50 is fed onto the feeding assembly 10. The moving assembly 20 includes multiple moving units 21 and guide rails 22. The guide rails 22 connect the feeding assembly 10, the assembly station 30, and the recycling device 40. The moving units 21 move the tooling plate 50 to the assembly station 30, and / or move the tooling plate 50 to the recycling device 40. There are multiple assembly stations 30, and the arrangement of the multiple assembly stations 30 is determined according to the type of tooling plate 50. The assembly stations 30 assemble the components of the tooling plate 50. The recycling device 40 is used to move the tooling plate 50 from the end of the guide rail 22 to the beginning of the guide rail 22.

[0058] Specifically, the feeding assembly 10 is positioned near the beginning of the guide rail 22 to move the parts to be assembled into the mounting positions of the tooling plate 50. The tooling plate 50, once loaded, is moved to the assembly station 30 via the moving unit 21 in the moving assembly 20. The tooling plate 50 is then assembled at the assembly station 30. Depending on the actual needs, the assembly station 30 can perform one or more steps, such as moving, welding, or gluing. After the tooling plate 50 completes all assembly at multiple assembly stations 30, the assembled product is discharged from the last assembly station 30. At this point, all mounting positions of the tooling plate 50 are empty. The empty tooling plate 50 is moved from the end of the guide rail 22 to the beginning of the guide rail 22 via the recycling device 40, where the feeding assembly 10 reloads it, completing the automated cycle.

[0059] In one embodiment, the above-described flexible production line is specifically used for the assembly production of mobile power supplies. The assembly station 30 includes a switch assembly station 31, a lampshade assembly station 32, a PCB board assembly station 33, a glue application station 34, a battery assembly and welding station 35, and a cover assembly station 36.

[0060] In one embodiment, the switch assembly station 31 includes a first robotic arm 311, a first support frame 312, a clamping member 313, a holding member 314, and a pushing member 315. The first robotic arm 311 is connected to the first support frame 312, and the clamping member 313, the holding member 314, and the pushing member 315 are respectively connected to the first support frame 312. The holding member 314 is used to hold the mobile power switch, the clamping member 313 is used to clamp the mobile power switch, and the pushing member 315 is used to push the mobile power switch to rotate.

[0061] The switch assembly station 31 is used to assemble the power bank switch with the power bank's lower cover. The power bank switch is a cylindrical button with a lever and a cross-shaped connector. The retaining member 314 is arc-shaped, matching the cylindrical button shape of the power bank switch. After the retaining member 314 holds the cylindrical button, the switch lever extends and is parallel to and fits against the plane of the support rod of the retaining member 313. The clamping member 313 is pushed by a cylinder and moves towards the plane of the support rod of the retaining member 313, pressing the lever against the plane of the support rod of the retaining member 313. After clamping, the first robotic arm 311 moves the switch to the switch position on the power bank's lower cover, the clamping member 313 is released, and the pushing member 315, under the action of a cylinder, pushes the lever to rotate through a slender push rod, so that the lever matches the slot in the lower cover.

[0062] In one embodiment, the lampshade assembly station 32 includes a second robotic arm 321 and a first suction cup 322. The second robotic arm 321 is connected to the first suction cup 322, which is used for picking up and placing the lampshade of the portable power supply. The cover assembly station 36 includes a third robotic arm 361 and a second suction cup 362, which is connected to the second suction cup 362, and is used for picking up and placing the cover of the portable power supply.

[0063] The lampshade assembly station 32 is used for assembling the lampshade and the PCB board, while the cover assembly station 36 is used for assembling the upper and lower covers of the power bank. The lampshade assembly station 32 and the cover assembly station 36 have similar structures, the difference being in the suction cup structure. Since the lampshade is composed of three small lampshades, the first suction cup 322 is also composed of three small suction cups, with a shape and distribution matching the lampshade. The second suction cup 362 is used for taking off and placing the power bank's upper cover, therefore it adopts a suction cup structure with a large contact area.

[0064] In one embodiment, the PCB assembly station 33 includes a fourth robotic arm 331, a second support frame 332, a third suction cup 333, and a solder gun 334. The fourth robotic arm 331 is connected to the second support frame 332, and the third suction cup 333 and the solder gun 334 are respectively connected to both ends of the second support frame 332. The third suction cup 333 is used for picking up and placing the power bank PCB board, and the solder gun 334 is used for spraying solder.

[0065] The PCB assembly station 33 is used for assembling the power bank PCB and the power bank's lower cover. A third suction cup 333 picks up the power bank PCB from the fixture and moves it to the PCB assembly position in the power bank's lower cover via a fourth robotic arm 331. The fourth robotic arm 331 then moves the solder gun 334, which sprays solder onto the solder points on the PCB. The solder gun 334 is a conventional technique, and its specific structure and principle will not be described in detail here.

[0066] In one embodiment, the adhesive application station 34 includes a fifth robotic arm 341 and a glue gun 342, which are connected together. The glue gun 342 is used to spray adhesive. The adhesive application station 34 is used for applying adhesive to a portable power bank battery. The fifth robotic arm 341 moves the glue gun 342, evenly applying the adhesive sprayed by the glue gun 342 to the battery surface.

[0067] The battery assembly and welding station 35 includes a sixth robotic arm 351, a third support frame 352, a welding torch 353, and a fourth suction cup 354. The sixth robotic arm 351 is connected to the third support frame 352, and the welding torch 353 and the fourth suction cup 354 are respectively connected to the third support frame 352. The fourth suction cup 354 is used for picking up and placing the power bank battery. The battery assembly and welding station 35 is used to move the power bank battery into the lower cover for assembly, and then weld the battery to the PCB board using the welding torch 353. The glue gun 342 and the welding torch 353 are both conventional techniques, and their specific structures and principles will not be described in detail here.

[0068] In one embodiment, the loading assembly 10 includes a loading robot 11 and a parts rack 12, wherein the loading robot 11 picks up parts from the parts rack 12 and moves them to the tooling plate 50.

[0069] Specifically, there are two parts racks 12 and two loading robots 11. The two loading robots 11 are located on the front side of the head end of the guide rail 22, and the two parts racks 12 are located on both sides of the loading robots 11. The loading robots 11 pick up parts from the parts racks 12 and place them on the tooling plate 50 of the recycling device 40.

[0070] The suction cups in the above embodiments all adopt a vacuum suction cup structure. The robotic arm adopts a robotic arm structure driven by Mitsubishi Electric.

[0071] In one embodiment, such as Figure 8-10 As shown, the moving component 20 also includes a guide rail frame 29, which supports the guide rail 22. The moving unit 21 is located below the guide rail 22. The moving unit 21 includes a retaining groove 23 and a power component 24. The power component 24 drives the retaining groove 23 to move along the direction of the guide rail 22. The moving unit 21 is connected to the bottom of the tooling plate through the retaining groove 23. The power component 24 drives the tooling plate to move from the first position to the second position along the direction of the guide rail 22, and then moves the tooling plate from the second position to the third position.

[0072] The guide rail bracket 29 supports the guide rail 22 at a certain height above the horizontal plane. The power assembly 24 and the retaining groove 23 are lower than the plane of the guide rail 22. The bottom of the tooling plate is provided with a retaining post that matches the retaining groove 23. When the tooling plate is placed on the guide rail 22, the retaining post extends into the bottom of the guide rail. The power assembly 24 drives the retaining groove 23 to move and match the retaining post. After the matching connection, the power assembly 24 drives the retaining groove 23 to move along the direction of the guide rail 22. The point of action of the movement is located on the back of the tooling plate, so it will not affect the parts placed on the front of the tooling plate. Furthermore, the segmented movement increases the movement distance.

[0073] The segmented movement is achieved using a movable plate 25, which has a predetermined length and a retaining slot 23 at each end. A power assembly 24 is connected to the middle of the movable plate 25. The retaining slot 23 at the front end of the movable plate 25 connects to a tooling plate, and the power assembly 24 drives the tooling plate from a first position to a second position. The retaining slot 23 at the rear end of the movable plate 25 connects to the tooling plate, and the power assembly 24 drives the tooling plate from the second position to a third position.

[0074] Since the movable plate 25 has a certain length and its connection point with the power assembly 24 is in the middle of the movable plate 25, the moving distance of the tooling plate can be extended by the movable plate 25. That is, the moving distance of the tooling plate is the sum of the stroke distance of the power assembly 24 and the length of the movable plate 25. Assuming that the first end of the movable plate 25 is the left end and the last end is the right end, when the power assembly 24 drives the movable plate 25 to the leftmost position of its stroke, the retaining groove 23 at the first end of the movable plate 25 connects with the tooling plate in the first position; the power assembly 24 drives the tooling plate 15 to the rightmost position of its stroke, at which point the tooling plate is in the second position, the retaining groove 23 at the first end of the movable plate 25 releases the tooling plate, the power assembly 24 moves to the left so that the retaining groove 23 at the last end of the movable plate 25 connects with the tooling plate, and then drives the tooling plate to the rightmost position of its stroke, at which point the tooling plate is in the third position.

[0075] The movable plate 25 has a hollow structure to reduce its weight, thereby reducing the load on the power assembly 24. The retaining groove 23 is semi-circular, and its shape matches the shape of the retaining post at the bottom of the tooling plate. The opening of the semi-circular groove 23 is perpendicular to the direction in which the tooling plate moves along the guide rail 22. The contact point between the inner wall of the retaining groove 23 and the retaining post of the tooling plate is the stress point. The power assembly 24 drives the retaining groove 23 of the movable plate 25 to move perpendicular to the guide rail direction, engaging the retaining post of the tooling plate through the side opening of the retaining groove 23. After the retaining groove 23 connects with the retaining post, the power assembly 24 drives the movable plate 25 to move along the guide rail 22, which in turn pulls the tooling plate along the guide rail 22.

[0076] The power assembly 24 includes a pusher 241 and a linear motion assembly 242. The pusher 241 is fixedly connected to the movable plate 25, and drives the movable plate 25 to move perpendicular to the guide rail 22. The opening of the retaining groove 23 is aligned with the perpendicular direction of the guide rail 22, and the retaining groove 23 engages or disengages with the retaining post at the bottom of the tooling plate via the pusher 241. The linear motion assembly 242 is connected to the pusher 241 and drives the pusher 241 to move along the guide rail 22.

[0077] The pusher 241 is a linear motor or a cylinder. In this embodiment, the pusher 241 is a cylinder, and the linear motion assembly 242 is a linear motor. Taking the direction of the guide rail as the x-direction and the direction perpendicular to the direction of the guide rail as the y-direction, the cylinder pushes the moving plate 25 to move in the y-direction, thereby achieving the matching and separation of the clamping groove 23 and the tooling plate clamping post. The linear motion assembly 142 drives the moving plate 25 to move in the x-direction, thereby pulling the tooling plate to move in the x-direction.

[0078] Multiple rollers 26 are provided on both sides of the guide rail 22 for supporting the tooling plate. There are multiple rollers 26 arranged in sequence. The two sides of the tooling plate contact the rollers 26, and the rollers 26 provide rolling friction, which has less resistance than sliding friction.

[0079] The system includes multiple limiting blocks 27, which are located on both sides of the guide rail 22. The height of the limiting grooves on the limiting blocks 27 matches the thickness of the tooling plate. The limiting blocks 27 are arranged in groups of four, distributed at the four corners. The width and length of adjacent limiting blocks match the dimensions of the tooling plate. Two limiting blocks 27 are provided on each side of the guide rail 22. The limiting blocks 27 restrict the direction of movement of the tooling plate on the guide rail 22, preventing the tooling plate from detaching from the side of the guide rail 22 during movement.

[0080] The system includes an anti-collision sensor 28, which is located on the side of the guide rail 22. The anti-collision sensor 28 is electrically connected to the power assembly 24 and is used to detect the movement status and distance of the tooling plates on the guide rail 22, thereby controlling the operation of the power assembly 24 and preventing collision damage to adjacent tooling plates.

[0081] In one embodiment, such as Figure 11-15 As shown, the mobile component 20 is provided with a recycling device 40 at each end, and the two recycling devices 40 are connected by a recycling conveyor belt 46, which is located below the guide rail 22.

[0082] The recycling device 40 includes a frame 45, a lifting assembly 41, a support frame 42, and a translation assembly 43. The lifting assembly 41 and the support frame 42 are located on the frame 45, and the translation assembly 43 is located on the support frame 42. The translation assembly 43 is used for the movement of the tooling plate on the support frame 42. The lifting assembly 41 is connected to the support frame 42 and is used for the movement of the support frame 42 between the plane where the guide rail 22 is located and the plane where the recycling conveyor belt 46 is located.

[0083] The frame 45 supports the lifting assembly 41, the support frame 42, and the translation assembly 43. Specifically, the frame 45 has a two-layer vertical structure. The lifting assembly 41 drives the support frame 42 to move up and down between the two layers of the frame 45. The height of the upper layer of the frame 45 matches the height of the guide rail of the moving assembly in the flexible production line, and the height of the lower layer of the frame 45 matches the height of the recycling conveyor belt in the flexible production line. The translation assembly 43 moves the tooling plate from the guide rail of the moving assembly to the support frame 42, or from the support frame 42 to the recycling conveyor belt. The lifting assembly 41 enables the tooling plate to move up and down between the plane of the recycling conveyor belt and the plane of the guide rail.

[0084] The support frame 42 includes a connecting rod 421 and at least two support rods 422. The support rods 422 are arranged in parallel, and the connecting rod 421 is located below the support rods 422 and connects the two support rods 422.

[0085] The widths of the two support rods 422 match the width of the tooling plate, serving as load-bearing supports for the tooling plate. A connecting rod 421 is located below the support rods 422 and is perpendicular to them; the connecting rod 421 is used to connect the two support rods 422.

[0086] The translation assembly 43 includes a conveyor belt 431, a first power component 432, and a transmission component 433. Transmission components 433 are respectively provided at both ends of the support rod 422. The first power component 432 drives the transmission components 433 to rotate, and the first power component 432 is connected to the connecting rod 421. The conveyor belt 431 is arranged parallel to the support rod 422, located inside the support rod 422, and surrounds the transmission components 433 at both ends of the support rod 422. The conveyor belt 431 is used to contact the tooling plate and drive the tooling plate to move.

[0087] The first power component 432 is a servo motor, the transmission component 433 is a gear, and a support wheel 434 is provided below the conveyor belt 431 for support. The servo motor is located on the connecting rod 421, driving the transmission component 433 to rotate, which in turn drives the cooperating conveyor belt 431 to rotate around the transmission components 433 on both sides. The conveyor belt 431 is tightly wrapped around the transmission components 433 at both ends of the bearing rod 422.

[0088] A rigid limiting support 423 is connected to the lower side of the support frame 42. The rigid limiting support 423 extends downward by a predetermined length and is higher than the plane where the support frame 42 is located. A sensor 424 is also included. The sensor 424 is located on the frame 45 at the start or end point of the moving range of the lifting assembly 41. In this embodiment, a sensor 424 is provided at both the start and end points to detect the movement of the support frame 42. By detecting whether the support frame 42 has moved into position, the sensor 424 determines whether to activate the translation assembly 43 to move the tooling plate.

[0089] Both the limit support 423 and the sensor 424 can be used to prevent collisions during the up-and-down movement of the support frame 42, thus avoiding damage to parts caused by excessive movement of the support frame 42.

[0090] The device includes a limiting component 44, which comprises a baffle 441 and a pressure roller 442. The baffle 441 is disposed on the support rod 422 and is used to limit the horizontal displacement of the tooling plate. The pressure roller 442 is disposed on the support rod 422, and the wheel surface of the pressure roller 442 is higher than the plane on which the support rod 422 is located. The wheel surface of the pressure roller 442 is used to contact the upper surface of the tooling plate to limit the vertical displacement of the tooling plate.

[0091] The number of baffles 441 includes at least two, each located on one of two parallel support rods 422. The width between them matches the width of the tooling plate, preventing the tooling plate from detaching from the conveyor belt 431 during movement and thus affecting its movement on the translation assembly 43. The height of the pressure roller 442 matches the thickness of the tooling plate. The pressure roller 442 presses the tooling plate vertically, limiting its vertical offset. At the same time, the pressure roller 442 rolls against the surface of the tooling plate, minimizing its impact on the horizontal movement of the tooling plate.

[0092] The lifting assembly 41 includes a lifting guide rail 411, a connecting block 412, and a second power component 413. The lifting guide rail 411 is mounted on the frame 45 and is arranged vertically to the horizontal plane.

The connecting block 412 is matched and connected to the lifting guide rail 411 and is connected to the support frame 42. The second power component 413 drives the connecting block 412 to move along the lifting guide rail 411. In this embodiment, the second power component is specifically a linear motor assembly.
