[0002] In the production process of FPC (Flexible Printed Circuit) products, SMT (Surface Mount Technology) pick-and-place machines are used to print and mount electronic components onto the FPC. Furthermore, to achieve uninterrupted production for the SMT pick-and-place machine, new tape needs to be added to the original reel before the old tape runs out, and the original reel is replaced with the new tape. Moreover, to ensure continuous feeding, the old tape on the original reel is usually cut, and the new tape on the new reel is connected to the old tape for use by the SMT pick-and-place machine. In traditional technology, new reels containing new tape are typically manually transported to the loading station, and the starting end of the new tape is unwound in preparation for cutting. This manual loading method is inefficient, affects production cycle time, and is extremely labor-intensive and resource-intensive. Utility Model Content

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] like Figures 1 to 2As shown, this utility model proposes a material strip feeding device 10, including a frame 100, a hopper mechanism 200 located at the bottom of the frame 100, a tray lifting mechanism 300 located between the bottom and middle of the frame 100, and a material strip pulling mechanism 400 located in the middle of the frame 100. The tray lifting mechanism 300 corresponds to and cooperates with the hopper mechanism 200 and the material strip pulling mechanism 400. The hopper mechanism 200 can store multiple reels 20; the tray lifting mechanism 300 can grab the reels in the hopper mechanism 200 at the lower position, remove the reels 20 from the hopper mechanism 200 and move them to a preset height position, so that the starting end of the material strip 22 in the reel 20 corresponds to the material strip pulling mechanism 400; the material strip pulling mechanism 400 can clamp the starting end of the material strip 22 and pull it out, continuously pulling the material strip 22 from the reel 20.

[0038] Specifically, the frame 100 may include a base frame 110 and a worktable 120 mounted on the base frame 110. The base frame 110 may be provided with a storage station for assembling a hopper mechanism 200; the side of the worktable 120 may be provided with a material handling station for assembling a material tray lifting mechanism 300; the worktable 120 may be provided with a material pulling station for assembling a material strip pulling mechanism 400.

[0039] Furthermore, the hopper mechanism 200 may include a hopper 210 slidably mounted on the base frame 110 at a storage station, and a hopper telescopic drive 220 connected to the hopper 210. The hopper 210 can store multiple reels 20, and the hopper telescopic drive 220 can drive the hopper 210 and the multiple reels 20 thereon to reciprocate. Moreover, the hopper lifting mechanism 300 may include a hopper lifting frame 310 located on the side of the workbench 120, and a hopper pick-and-place hook 320 connected to the hopper lifting frame 310, the hopper pick-and-place hook 320 correspondingly engaging with the hopper 210. The hopper lifting frame 310 can move up and down on the side of the workbench 120, and the hopper pick-and-place hook 320 can pick up the reels 20 in the hopper 210. Furthermore, the strip pulling mechanism 400 may include a pulling base 410 and a telescopic pulling drive 420 disposed on the worktable 120, and a strip clamping structure 430 slidably disposed on the pulling base 410 and connected to the telescopic pulling drive 420.

[0040] When feeding the strip 22 onto the reel 20, multiple reels 20 with strips can be pre-placed in the reel bin 210 of the hopper mechanism 200. When it is necessary to retrieve the reel 20 from the reel bin 210, the reel lifting frame 310 of the reel lifting mechanism 300 can be used to drive the reel pick-up hook 320 to descend to the retrieval position. Then, the reel telescopic drive 220 drives the reel bin 210 to slide on the base frame 110, so that the reel 20 in the reel bin 210 and the reel pick-up hook 320 of the reel lifting mechanism 300 are engaged. Correspondingly, the material tray lifting frame 310 can be used to drive the material tray pick-up hook 320 to rise and hook the reel 20, and continue to drive the material tray pick-up hook 320 to hook the reel 20 to rise to the discharge position; then, the telescopic pulling drive member 420 of the material strip pulling mechanism 400 can be used to drive the material strip clamping structure 430 to extend to the discharge position, and the material strip clamping structure 430 can clamp the starting end of the material strip 22 on the reel 20 at the discharge position, and pull the material strip to discharge, so as to pull the material strip 22 out of the reel 20.

[0041] Furthermore, such as Figures 2 to 4 As shown, the material hopper 210 of the material hopper mechanism 200 may include a storage base 212 slidably mounted on the base frame 110, a storage slot 214 engaged on the storage base 212, and multiple storage racks 216 arranged side-by-side in the receiving cavity 2142 of the storage slot 214. The material hopper hook 320 corresponds to and engages with the storage racks 216. The storage base 212 is connected to the material hopper telescopic drive 220. The material hopper telescopic drive 220 can drive the storage base 212 and the storage slot 214 on it to reciprocate, thereby driving the multiple storage racks 216 on the storage slot 214 and the reel 20 on it to reciprocate, so that one storage rack 216 on the storage slot 214 is positioned at a position corresponding to the material hopper hook 320. The material tray pick-and-place hook 320 can simultaneously grab the storage rack 216 and the coil 20 on it, and move it up and down under the drive of the material tray lifting frame 310.

[0042] Furthermore, the storage rack 216 may include a main rack 2162 that is fitted into the receiving cavity of the storage slot 214, and a rack protrusion 2164 that protrudes from one side of the main rack 2162. The main rack 2162 can support and hold the reel 20. The rack protrusion 2164 protruding from one side of the main rack 2162 can be used to position the starting end of the strip 22 of the reel 20 on the main rack 2162, so that the strip pulling mechanism 400 can clamp and pull the starting end of the strip 22. It can also be used to cooperate with the reel pick-and-place hook 320, so that the reel lifting mechanism 300 can hook and lift the storage rack 216 and the reel 20 on it.

[0043] Furthermore, the main tray frame 2162 has a recessed chuck cavity 2163 in the middle, and both sides of the main tray frame 2162 are provided with positioning slots or positioning protrusions that engage with the cavity walls of the receiving cavity. The chuck cavity 2163 in the middle of the main tray frame 2162 can be used to hold the coil 20; while the snap-fit ​​structures (i.e., positioning slots or positioning protrusions) on both sides of the main tray frame 2162 can be used to movably hold the storage rack 216 in the receiving cavity of the storage slot 214 from both sides, which facilitates the positioning and confinement of the storage rack 216 in the storage slot 214.

[0044] Moreover, such as Figures 6 to 8 As shown, the top of the tray frame protrusion 2164 may be provided with a discharge groove 2165, and the bottom of the tray frame protrusion 2164 is provided with a hook groove 2166, and the tray pick-up and drop hook 320 is correspondingly engaged with the hook groove 2166. The discharge groove 2165 on the top of the tray frame protrusion 2164 can be used to position the starting end of the material strip 22 of the coil 20; while the hook groove 2166 on the bottom of the tray frame protrusion 2164, which engages with the tray pick-up and drop hook 320, can be used to easily hook the tray rack 216. When it is necessary to unload the reel 20 on a certain storage rack 216, the reel pick-up hook 320 can be positioned below the bottom of the reel frame protrusion 2164 of the storage rack 216 under the drive of the reel lifting frame 310. When the reel pick-up hook 320 is driven to rise by the reel lifting frame 310, the storage rack 216 can be hooked by the hook groove 2166.

[0045] Furthermore, the storage rack 216 may include a discharge limiting block 2168 rotatably mounted on the top of the rack protrusion 2164, and the discharge limiting block 2168 may be located on the side of the discharge groove 2165. When the material strip in the discharge groove 2165 at the top of the rack protrusion 2164 of the storage rack 216 is clamped and discharged by the material strip pulling mechanism 400, the discharge limiting block 2168 can be rotated to press against the top surface of the material strip in the discharge groove 2165, thereby preventing the material strip from shifting during the discharge process.

[0046] In addition, such as Figures 1 to 4 As shown, the hopper telescopic drive component 220 may include a linear motor drive module 222 and a telescopic support frame 224 mounted on the base frame 110. The storage base 212 is connected to the linear motor drive module 222 and slidably mounted on the telescopic support frame 224. The linear motor drive module 222 can drive the storage base 212 and the storage tray 210 to reciprocate along the telescopic support frame 224. The telescopic support frame 224 can support and guide the storage base 212 and the storage tray 210, ensuring stability and reliability.

[0047] In addition, such as Figures 5 to 6As shown, the tray lifting mechanism 300 includes a tray lifting base plate 310 located on the side of the workbench 120, a tray lifting motor 314 mounted on the tray lifting base plate 312, and a tray direct-moving structure 316 connected to the tray lifting motor 314. A tray pick-up / placement hook 320 is connected to the tray direct-moving structure 316 and slides vertically on the tray lifting base plate 312. The tray lifting motor 314 drives the tray direct-moving structure 316, causing the tray pick-up / placement hook 320 to reciprocate along a vertical straight line (i.e., lifting and lowering). Furthermore, the tray direct movement structure 316 may include a pulley drive structure arranged vertically on the tray lifting base plate 312. This pulley drive structure may include a first pulley and a second pulley arranged vertically on the tray lifting base plate 312, and a drive belt disposed between the first and second pulleys. The tray lifting motor 314 is connected to the first pulley (or the second pulley), and the tray pick-and-place hook 320 is connected to the drive belt. Alternatively, the tray direct movement structure 316 may also be a screw and nut drive structure, or a gear and rack drive structure, etc.

[0048] Furthermore, the tray pick-up hook 320 may include a pick-up hook base 322 connected to the tray direct-movement structure 316 and slidably mounted on the tray lifting base plate 312, and a tray pick-up hook body 324 located at the end of the pick-up hook base 322. The tray direct-movement structure 316 can drive the pick-up hook base 322 and the tray pick-up hook body 324 to move up and down. Moreover, the pick-up hook base 322 may be bent and extended from one side of the workbench 120 (such as the first side) to the other side of the workbench 120 (such as the second side adjacent to the first side), and correspond to the hopper mechanism 200 located outside the second side of the workbench. Moreover, the tray lifting frame 310 may be located on the first side of the workbench 120, which can reduce the space occupied by the tray lifting mechanism 300 on the second side, making the tray pick-up hook 320 and the tray hopper 210 more compact and convenient for picking up materials.

[0049] In addition, such as Figure 5 , Figure 9 , Figure 10 As shown, the telescopic pulling drive 420 of the strip pulling mechanism 400 may include a telescopic pulling motor 422 mounted on the worktable 120, and a telescopic pulling screw structure 424 connected to the telescopic pulling motor 422. The telescopic pulling screw structure 424 is connected to the strip clamping structure 430. The telescopic pulling motor 422 drives the telescopic pulling screw structure 424 to work, causing the telescopic pulling screw structure 424 to drive the strip clamping structure 430 to move telescopically. This causes the strip clamping structure 430 to move to the position corresponding to the starting end of the strip 22 of the reel 20 on the storage rack 216, which is raised to a preset height by the reel lifting mechanism 300. The strip clamping structure 430 then clamps and conveys the starting end of the strip.

[0050] Furthermore, the material strip clamping and pulling structure 430 may include a clamping base 432 connected to the telescopic pulling screw structure 424 and slidably disposed on the pulling base 410, a main clamping wheel structure 434 disposed at the bottom of the clamping base 432, and an auxiliary clamping wheel structure 436 disposed at the top of the clamping base 432. A clamping and pulling gap is formed between the main clamping wheel structure 434 and the auxiliary clamping wheel structure 436. The telescopic pulling screw structure 424 can drive the main clamping wheel structure 434 to move below the starting end of the material strip and move the auxiliary clamping wheel structure 436 above the starting end of the material strip. The auxiliary clamping wheel structure 436 can clamp the starting end of the material strip at the clamping and pulling gap, and the material strip can be pulled out by the main clamping wheel structure 434 and the auxiliary clamping wheel structure 436.

[0051] Furthermore, the main clamping wheel structure 434 may include a main clamping frame 4342 and a main clamping motor 4344 located at the bottom of the clamping base 432, a main clamping shaft 4345 connected to the main clamping motor 4344 and rotatably mounted on the main clamping frame 4342, and main clamping wheels 4346 and a main drive gear 4348 respectively located on both sides of the main clamping shaft 4345. The main clamping motor 4344 can drive the main clamping shaft 4345 to rotate, thereby driving the main clamping wheels 4346 and the main drive gear 4348 to rotate.

[0052] Furthermore, the auxiliary clamping wheel structure 436 may include an auxiliary clamping lifting structure 4362 located on the top of the clamping base 432, an auxiliary clamping frame 4364 connected to the auxiliary clamping lifting structure 4362, an auxiliary clamping shaft 4365 rotatably mounted on the auxiliary clamping frame 4364, and auxiliary clamping wheels 4366 and auxiliary transmission gears 4368 respectively located on both sides of the auxiliary clamping shaft 4365. The auxiliary transmission gears 4368 are correspondingly engaged with the main drive gear 4348. The auxiliary clamping lifting structure 4362 can drive the auxiliary clamping frame 4364 and its auxiliary clamping wheels 4366 and auxiliary transmission gears 4368 to move up and down, so that the auxiliary transmission gears 4368 mesh with the main drive gear 4348, and the auxiliary clamping wheels 4366 and the main clamping wheels 4346 are correspondingly engaged vertically to clamp the starting end of the material strip in the clamping gap between them. Moreover, the main drive gear 4348 can drive the auxiliary transmission gear 4368 to rotate, which can drive the auxiliary clamping wheel 4366 to rotate, so that the auxiliary clamping wheel 4366 and the main clamping wheel 4346 rotate simultaneously to pull the material strip clamped between them out.

[0053] The material feeding device 10 provided by this utility model can automatically pick up and feed material from a reel containing material strips, and can automatically pull out the starting end of the material strip on the reel in preparation for cutting. Compared with the traditional manual feeding method, it can greatly improve the feeding and discharging efficiency of the reel, improve product production efficiency, and save a lot of manpower and material resources.
