Description

Technical Field

[0001] This utility model relates to the field of flexible board production technology, and in particular to a material tray unloading device. Background Technology

[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 connected 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 from the reel, 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.

[0003] Furthermore, before cutting the old strip on the original reel, it is usually necessary to unload the old strip, that is, pull the unused old strip off the reel so that it can be cut from the part closest to the reel. However, in traditional technology, the unused old strip is usually pulled off the reel manually, which is not only inefficient but also prone to contaminating the strip and affecting product quality.

Then, the unloading reel can be retrieved from the outside by a manipulator at the bottom of the frame of the unloading trough frame and moved from the outside of the unloading trough frame. The material is delivered to the outside of the strip conveyor frame of the unloading platform. During the transfer of the reel, the reel can be rotated simultaneously to pull out the material, causing the pulled-out strip to fall sequentially into the material channel of the unloading trough frame and the conveyor channel of the strip conveyor frame. Then, the strip in the conveyor channel of the strip conveyor frame is conveyed by the strip conveyor drive on the unloading conveyor mechanism, continuously pulling out the strip from the reel on the picking robot located outside the strip conveyor frame. The pulled-out strip is then transferred to the unloading groove of the unloading trough frame for temporary storage until all excess strip on the reel is pulled out. During this process, unused old strip on the original reel can be automatically pulled out, greatly improving the pulling and unloading efficiency. The unloading groove on the unloading trough frame also stores and protects the unloaded strip, preventing contamination and ensuring product quality. Attached Figure Description

[0034] 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.

[0035] like Figures 1 to 2As shown, this utility model proposes a material tray unloading device 10, including an unloading frame 100, a picking robot 200 and an unloading conveying mechanism 300 mounted on the unloading frame 100, and a material strip unloading mechanism 400 that cooperates with both the picking robot 200 and the unloading conveying mechanism 300. The picking robot 200 can pick up the material tray 20 to be unloaded from other workstations and move the material tray 20 to one side of the unloading conveying mechanism 300. During the movement of the material tray 20, preliminary material pulling and unloading can also be performed, so that the pulled material strip falls on the material strip unloading mechanism 400 and the unloading conveying mechanism 300. The remaining material strip on the material tray can be fully pulled and unloaded by the material strip unloading mechanism 400, and the pulled material strip is stored in the material strip unloading mechanism 400.

[0036] Furthermore, the unloading rack 100 may include a frame 110 and an unloading platform 120 disposed on the frame 110. A picking robot 200 may be disposed at the bottom of the frame 110, located outside the unloading platform 120. Moreover, the unloading conveying mechanism 300 may include a strip conveyor frame 310 disposed on the unloading platform 120 and having a conveying channel 302, and a strip conveying drive 320 disposed on the strip conveyor frame 310. The picking robot 200 corresponds to and cooperates with the strip conveyor frame 310. Furthermore, the strip unloading mechanism 400 may include a trough rotation drive 410 disposed on the side of the unloading platform 120, and an unloading trough frame 420 with an unloading groove 402 connected to the trough rotation drive 410. The top of the unloading trough frame 420 has a trough channel 404 corresponding to and cooperating with the conveying channel 302, and the trough channel 404 communicates with the unloading groove 402.

[0037] In its initial state, the unloading tray 420 of the strip unloading mechanism 400 is folded, and its side is parallel to the side of the unloading platform 120. When it is necessary to unload the strip on the reel 20, the unloading tray 420 can be unfolded by the tray rotation drive 410, so that the side of the unloading tray 420 is perpendicular to the side of the unloading platform 120, and the tray channel 404 on the unloading tray 420 is connected to the conveying channel 302 of the strip conveyor 310 of the unloading conveyor mechanism 300. Then, the unloading reel 20 can be picked up from the outside by the picking robot 200 at the bottom of the frame 110 of the unloading tray 100, and the reel 20 can be unloaded from the outside of the unloading tray 420. The material is transferred to the outside of the material conveyor 310 of the unloading platform 120. During the transfer of the reel 20, the reel 20 can be rotated to pull out the material, so that the pulled-out material falls into the material channel 404 of the unloading trough frame 420 and the conveying channel 302 of the material conveyor 310 in sequence. Then, the material conveyor drive 320 on the unloading conveyor mechanism 300 can convey the material in the conveying channel 302 of the material conveyor 310, so that the material in the reel 20 on the picking robot 200 located outside the material conveyor 310 can be continuously pulled out, and the pulled-out material is transferred to the unloading groove 402 of the unloading trough frame 420 for temporary storage, until all the excess material in the reel 20 is pulled out. During this process, the unused old material strip on the original roll 20 can be automatically pulled out, which can greatly improve the material pulling and unloading efficiency. The unloaded material strip can also be stored and protected by the unloading groove 402 on the unloading trough frame 420 to avoid contamination of the material strip and ensure product quality.

[0038] Specifically, such as Figures 1 to 2 As shown, the frame 110 of the unloading rack 100 may include a bottom frame plate, an unloading platform 120 may protrude from one side of the bottom frame plate, and a picking robot 200 may be located on the other side of the bottom frame plate, so that the two can be arranged side by side (e.g., along the transverse direction of the bottom frame plate) on the bottom frame plate, facilitating the picking robot 200 to move the reel 20 from one side of the unloading platform 120 to the other side. Moreover, the unloading conveying mechanism 300 and the conveying channel 302 may be arranged along the extension direction of the unloading platform 120, arranged side by side with the picking robot 200; the strip unloading mechanism 400 may be located on one side of the unloading platform 120, also arranged side by side with the picking robot 200.

[0039] Furthermore, such as Figures 3 to 5As shown, the material conveyor frame 310 of the unloading conveyor mechanism 300 may include a conveyor base 312 disposed on the unloading platform 120, a fixed conveyor frame 314 fixedly disposed on one side of the conveyor base 312, and a movable conveyor frame 316 slidably disposed on the other side of the conveyor base 312. A conveying channel 302 is formed between the fixed conveyor frame 314 and the movable conveyor frame 316. The material conveyor drive unit 320 may be disposed on the fixed conveyor frame 314 and / or the movable conveyor frame 316. The fixed conveyor frame 314 and the movable conveyor frame 316 may be arranged side by side on the unloading platform 120, both arranged along the extending direction of the unloading platform 120. Moreover, by sliding the movable conveyor frame 316 on the conveyor base 312, the movable conveyor frame 316 can be moved closer to or further away from the fixed conveyor frame 314, thereby adjusting the width of the conveying channel 302 and enabling the conveying of material belts of different sizes.

[0040] Furthermore, the fixed conveyor frame 314 may include a first limiting frame disposed on the conveyor base 312 along the extension direction of the unloading platform 120, a first guide protrusion protruding from the inner side of the first limiting frame, and a first guide wheel rotatably disposed on the inner side of the first limiting frame and located at both ends of the first guide protrusion. The first guide protrusion can guide and support the material belt in the conveyor channel 302 from one side, and the first guide wheel can guide the material belt into or out of the conveyor channel 302.

[0041] Furthermore, the movable conveyor frame 316 may include a second limiting frame slidably disposed on the conveyor base 312 along the extension direction of the unloading platform 120, a limiting frame telescopic drive member disposed on the conveyor base 312 and connected to the second limiting frame, a second guide protrusion protruding from the inner side of the second limiting frame, and a second guide wheel rotatably disposed on the inner side of the second limiting frame and located at both ends of the second guide protrusion. The second limiting frame is disposed opposite to the first limiting frame, forming a conveying channel 302 between them. Moreover, the limiting frame telescopic drive member can drive the second limiting frame to reciprocate on the conveyor base 312 to adjust the distance between the second limiting frame and the first limiting frame, thereby adjusting the width of the conveying channel 302. Furthermore, the second guide protrusion may be disposed opposite to the first guide protrusion, providing guidance and support for the material belt in the conveying channel 302 from the other side; the second guide wheel may be disposed opposite to the first guide wheel, allowing the material belt to be guided or unguided into the conveying channel 302 via the corresponding first and second guide wheels.

[0042] Furthermore, the material conveying drive 320 of the unloading conveying mechanism 300 can be mounted on the fixed conveyor frame 314 and / or the movable conveyor frame 316. Moreover, one or more material conveying drive 320s can be provided to drive the material conveying in the conveying channel 302. In this embodiment, a material conveying drive 320 can be provided at each end of the fixed conveyor frame 314, driving the material conveying from both ends of the conveying channel 302. Furthermore, each material conveying drive 320 can include a main conveying wheel structure 322 and an auxiliary conveying wheel structure 324 correspondingly mounted on the fixed conveyor frame 314. The main conveying wheel structure 322 and the auxiliary conveying wheel structure 324 can partially protrude into the conveying channel 302, corresponding to and cooperating with guide protrusions on the fixed conveyor frame 314 and the movable conveyor frame 316, allowing for clamping and conveying of the material conveying in the conveying channel 302 from both the upper and lower sides.

[0043] Further, the main conveyor wheel structure 322 may include a material belt conveyor motor 3222 mounted on the unloading platform 120, a main material belt conveyor shaft 3224 connected to the material belt conveyor motor 3222 and rotatably mounted on the fixed conveyor frame 314, and main conveyor rollers 3226 and main conveyor gears 3228 respectively mounted at both ends of the main material belt conveyor shaft 3224; correspondingly, the auxiliary conveyor wheel structure 324 may include a conveyor wheel lifting member 3242 mounted on the fixed conveyor frame 314, an auxiliary conveyor wheel frame 3244 connected to the conveyor wheel lifting member 3242, an auxiliary material belt conveyor shaft 3245 rotatably mounted on the auxiliary conveyor wheel frame 3244, and auxiliary conveyor rollers 3246 and auxiliary conveyor gears 3248 respectively mounted at both ends of the auxiliary material belt conveyor shaft 3245. The auxiliary conveyor gear 3248 is correspondingly engaged with the main conveyor gear 3228, and the auxiliary conveyor rollers 3246 and main conveyor rollers 3226 are correspondingly engaged and both located in the conveying channel 302. In addition, the conveyor wheel lifting component 3242 can be configured as a motor-driven structure or a cylinder-driven structure.

[0044] In the initial state, the main conveying roller 3226 of the main conveying wheel structure 322 can be located on the lower side of the conveying channel 302, and the auxiliary conveying roller 3246 of the auxiliary conveying wheel structure 324 can be located on the upper side of the conveying channel 302. When the material reel 20 is moved from one side (the side closer to the material strip unloading mechanism 400) to the other side (the side farther from the material strip unloading mechanism 400) of the unloading conveying mechanism 300 by the material handling robot 200, the material strip will be pulled out from the reel 20 and laid flat in the conveying channel 302. The two sides of the material strip can fall onto the first guide protrusion of the fixed conveying frame 314 and the second guide protrusion of the movable conveying frame 316, and fall onto the main conveying roller 3226 of the main conveying wheel structure 322. At this time, the conveying wheel lifting member 32 of the auxiliary conveying wheel structure 324 can be used to lift the material strip. 42 drives the auxiliary conveyor frame 3244 to descend, causing the auxiliary conveyor roller 3246 and auxiliary conveyor gear 3248 on the auxiliary conveyor frame 3244 to fall to a preset position, and causing the auxiliary conveyor roller 3246 to press onto the material belt on the main conveyor roller 3226, and causing the auxiliary conveyor gear 3248 to mesh with the main conveyor gear 3228; in addition, the main material belt conveyor shaft 3224 and the main conveyor roller 3226 and the main conveyor gear 3228 on it can be driven to rotate by the material belt conveyor motor 3222, and the main conveyor gear 3228 on it can be driven to rotate, thereby driving the auxiliary conveyor roller 3246 to rotate, so as to clamp and convey the material belt between the auxiliary conveyor roller 3246 and the main conveyor roller 3226, thereby pulling the material belt on the reel 20 out.

[0045] In addition, such as Figures 6 to 8 As shown, the material trough rotation drive 410 of the material strip unloading mechanism 400 may include a material trough rotation base plate 412 disposed on the side of the unloading platform 120, a material trough rotation motor 414 disposed on the material trough rotation base plate 412, a material trough rotation shaft 416 connected to the material trough rotation motor 414, and a material trough rotation seat 418 disposed on the material trough rotation shaft 416. The material trough rotation seat 418 is connected to the unloading trough frame 420. The material trough rotation motor 414 can drive the material trough rotation shaft 416 to rotate, which can drive the material trough rotation seat 418 to rotate, thereby driving the unloading trough frame 420 to rotate, so that the unloading trough frame 420 can rotate from a folded state to an unfolded state for receiving and unloading materials. When the unloading trough frame 420 is in the folded state, it can save its occupied space; while when the unloading trough frame 420 is in the unfolded state, the material trough channel 404 of the unloading trough frame 420 can be connected to the conveying channel 302, which is convenient for receiving and conveying the material strip.

[0046] Furthermore, the unloading trough frame 420 may include a trough main frame 422 connected to the trough rotation drive 410, and a pressing frame structure 424 disposed on the top of the trough main frame 422. The trough main frame 422 has an unloading groove 402 inside and a trough channel 404 communicating with the unloading groove 402 on the top. The pressing frame structure 424 is located on the top of the trough channel 404. By setting a pressing frame structure 424 on the top of the material trough main frame 422 of the unloading trough frame 420, when the material strip on the reel 20 is pulled out by the picking robot 200, passes through the material trough channel 404 at the top of the material trough main frame 422, and passes through the conveying channel 302 between the fixed conveying frame 314 and the movable conveying frame 316 of the unloading conveying mechanism 300, and is clamped and pulled out by the material strip conveying drive 320, the material strip can be pressed down from above the material trough channel 404. This causes the material strip on the reel 20 to continuously move towards the unloading trough frame 420 under the action of the material strip conveying drive 320, and fall from the material trough channel 404 into the unloading groove 402 of the material trough main frame 422, temporarily storing the unloaded material strip and preventing it from being contaminated or damaged. During the unloading process, the material strip in the material channel 404 is pressed down by the pressing frame structure 424 to prevent it from falling outside the unloading trough frame 420. In addition, after the material strip is docked, the material strip conveyor drive 320 can be driven to rotate in reverse to collect the material strip that has fallen into the unloading groove 402.

[0047] Furthermore, the pressing frame structure 424 may include a pressing lifting member 4242 disposed on one side of the top of the main frame 422 of the material trough, a pressing connecting plate 4244 connected to the pressing lifting member 4242, and a pressing top plate 4246 connected to the pressing connecting plate 4244. The pressing top plate 4246 is located in the material trough channel 404 and extends along the length of the material trough channel 404. The pressing lifting member 4242 can drive the pressing connecting plate 4244 and the pressing top plate 4246 thereon to move up and down, so that the pressing top plate 4246 falls into the material trough channel 404 or rises above the material trough channel 404. When the material strip on the reel 20 is pulled out by the robotic arm 200, the pressing plate 4246 can be positioned above the material channel 404 to facilitate the material strip falling into the material channel 404. After the material strip falls into the material channel 404, the pressing plate 4246 can be lowered into the material channel 404 to press the material strip firmly into the material channel 404. Moreover, the pressing plate 4246 can be extended along the length of the material channel 404, and its length can be set to be relatively long to better press most of the material strip passing through the material channel 404 into the material channel 404, so that the material strip falls better into the unloading groove 402 when it is unloaded from the reel 20. In addition, the pressing lifting component 4242 can be configured as a drive cylinder.

[0048] Furthermore, the material channel 404 has a discharge end near the discharge platform 120 and a feed end away from the discharge platform 120. The bottom surface of the pressure plate 4246 can be inclined upward from the feed end to the discharge end. This allows the bottom surface of the pressure plate 4246 to be set as an incline, so that it can press the material strip tightly at the feed end and press it loosely or even separate it from the material strip at the discharge end. This prevents the material strip from moving out of the material channel 404 from the feed end during discharge, further ensuring that the material strip can fall fully into the discharge groove 402 during discharge.

[0049] Furthermore, the unloading trough frame 420 may include a trough adjustment structure 428 disposed on the trough main frame 422, and a pressing frame structure 424 disposed on the trough adjustment structure 428. The width of the trough channel 404 can be adjusted by the trough adjustment structure 428 to accommodate material strips of different sizes, and the material strip falling into the trough channel 404 can also be limited. Further, the trough adjustment structure 428 may include a trough telescopic drive member 4282 disposed on the trough main frame 422, and a trough adjustment plate 4284 connected to the trough telescopic drive member 4282. The trough adjustment plate 4284 is disposed on one side of the trough main frame 422 and forms a trough channel 404 between the opposite side of the trough main frame 422, and the pressing frame structure 424 is disposed on the trough adjustment plate 4284. The material trough extension drive 4282 can drive the material trough adjustment plate 4284 to extend and retract, thereby adjusting the distance between the material trough adjustment plate 4284 and the other side of the material trough main frame 422, which in turn adjusts the width of the material trough channel 404. Moreover, when the material trough adjustment plate 4284 is extended and retracted by the material trough extension drive 4282, the pressure frame structure 424 can also be extended and retracted together, so that the pressure top plate 4246 of the pressure frame structure 424 is always directly above the material trough channel 404.

[0050] Furthermore, each end of the top of the trough main frame 422 can be provided with a guide shaft 429, and the two ends of the trough adjusting plate 4284 can be movably mounted on the two guide shafts 429 respectively. The two guide shafts 429 at the top of the trough main frame 422 can support and guide the material strip from the feeding end to the unloading end of the trough main frame 422, and can also provide movable support from both ends of the trough adjusting plate 4284. When the trough adjusting plate 4284 is driven by the trough telescopic drive component 4282, the trough adjusting plate 4284 can reciprocate along the two guide shafts 429, allowing for smooth and convenient adjustment. In addition, the trough telescopic drive component 4282 can be configured as a cylinder-driven structure.

[0051] It should be noted that in this invention, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
