[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 2 As shown, this utility model proposes a circuit board loading and conveying device 10, including a device frame, a tray conveying mechanism 100, a tray storage and distribution mechanism 200, and a receiving and transferring mechanism 300 mounted on the device frame. The receiving and transferring mechanism 300 can receive materials from other workstations (i.e., receive multiple stacked trays) and transfer the received stacked trays to the tray conveying mechanism 100. The tray storage and distribution mechanism 200 stores and distributes the trays one by one onto the tray conveying mechanism 100, which then transports the trays to the next workstation.

[0036] Specifically, the tray conveying mechanism 100 may include a conveying base 110 mounted on a frame, a conveying telescopic drive member 120 arranged side-by-side on both sides of the conveying base 110, a conveying frame 130 slidably mounted side-by-side on both sides of the conveying base 110, and a conveyor belt structure 140 mounted on each conveyor frame 130. Each conveying telescopic drive member 120 is connected to one conveyor frame 130. Furthermore, the tray storage and distribution mechanism 200 may include a tray storage compartment 210 mounted on the top of the two conveyor frames 130, telescopic tray distribution structures 220 mounted on the sides of the two conveyor frames 130 respectively, and a lifting tray distribution support member 230 mounted between the two conveyor frames 130. The telescopic tray distribution structure 220 is located below the tray storage compartment 210 and above the conveyor belt structure 140, while the lifting tray distribution support member 230 is located between the two conveyor belt structures 140 and below the tray storage compartment 210. Furthermore, the material receiving and transplanting mechanism 300 may include a transplanting base 310 mounted on the equipment frame, a linear drive module 320 mounted on the transplanting base 310 and extending along the length of the conveyor frame 130, and a lifting receiving platform 330 slidably mounted on the transplanting base 310 and connected to the linear drive module 320. The lifting receiving platform 330 is located between the two conveyor belt structures 140 and below the storage compartment 210.

[0037] The two conveyor frames 130 are moved away from each other by the conveyor telescopic drive 120 of the tray conveying mechanism 100. Then, the linear drive module 320 of the receiving and transferring mechanism 300 drives the lifting receiving platform 330 to move linearly, so that the lifting receiving platform 330 can receive multiple stacked pallets loaded with circuit board products from other workstations and move the stacked pallets to below the storage compartment 210 at the top of the two conveyor frames 130 of the tray conveying mechanism 100. Then, the lifting receiving platform 330 can lift the multiple pallets it carries into the storage compartment 210. Then, the two conveyor frames 130 are moved closer to each other by the conveyor telescopic drive 120 of the tray conveying mechanism 100. The telescopic tray-separating structure 220 below the storage compartment 210 supports and limits the pallets in the storage compartment 210 from the bottom. 30 can be reset; then, when it is necessary to discharge the pallet in the storage bin 210 to the conveyor belt structure 140 on the two conveyor frames 130 of the pallet conveying mechanism 100, the lifting and lowering support member 230 can be moved to support the pallet in the storage bin 210 from the bottom, and the telescopic splitting structure 220 can be retracted from the bottom of the storage bin 210, so that one pallet at the bottom of the storage bin 210 is unloaded onto the lifting and lowering support member 230; then, the telescopic splitting structure 220 can be extended from the bottom of the storage bin 210 to support and limit the pallet at the bottom of the storage bin 210, and the lifting and lowering support member 230 can lower the pallet on it, so that the pallet falls onto the conveyor belt structure 140 on the two conveyor frames 130 of the pallet conveying mechanism 100, and the pallet is automatically transported to the next station through the two conveyor belt structures 140.

[0038] In addition, such as Figures 3 to 4 As shown, the conveying base 110 of the tray conveying mechanism 100 may include a first base 112 and a second base arranged side by side on the equipment frame, and the receiving and transferring mechanism 300 may be disposed between the first base 112 and the second base. By separating the first base 112 and the second base, a gap is formed between them, so that the receiving and transferring mechanism 300 is located in the gap between the two conveyor frames 130 (and the two conveyor belt structures 140), which facilitates the transfer of the tray to the storage compartment 210 between the two conveyor frames 130 by the receiving and transferring mechanism 300.

[0039] Furthermore, each conveyor telescopic drive component 120 may include a conveyor telescopic drive motor 122 located in the middle of the first base 112 or the second base, a conveyor screw transmission structure 124 connected to the conveyor telescopic drive motor 122, and a guide slide structure 126 respectively located on both sides of the first base 112 or the second base. The conveyor screw transmission structure 124 is connected to the conveyor frame 130. The conveyor telescopic drive motor 122 can drive the conveyor screw transmission structure 124 to operate, causing the conveyor screw transmission structure 124 to drive the conveyor frame 130 to move. This allows the two conveyor frames 130 to move closer or further apart, thereby causing the conveyor belt structures 140 on the two conveyor frames 130 to move closer or further apart. This not only accommodates pallets of different sizes but also facilitates the clamping and support of pallets received and transferred from the receiving and transferring mechanisms 300 on both sides via the telescopic tray-separating structure 220 on the conveyor frame 130. In addition, by providing guide slide structures 126 on both sides of the conveying screw drive structure 124, the conveying frame 130 can be slidably supported from both sides, making the movement of the conveying frame 130 more stable and reliable.

[0040] Furthermore, the conveying telescopic drive component 120 may also include an intermediate transmission structure connecting the conveying telescopic drive motor 122 and the conveying screw transmission structure 124. This intermediate transmission structure may be a belt drive structure or a chain drive structure. Moreover, both the first base 112 and the second base may include a conveying base 110 plate and a side mounting plate located on the side of the middle portion of the conveying base 110 plate. The conveying telescopic drive motor 122 and the intermediate transmission structure may be located on the side mounting plate, and the conveying screw transmission structure 124 may be located in the middle portion of the conveying base 110 plate. The guide slide structure 126 may include a guide rail and a guide frame located at the end of the conveying base 110 plate, and a sliding base slidably disposed on the guide rail and movably sleeved on the guide frame. The conveying frame 130 is disposed on the sliding base.

[0041] In addition, the storage compartment 210 may include side compartment plates 212 that are vertically protruding from the top of the two conveyor frames 130 respectively; and the telescopic tray structure 220 may include a telescopic tray drive frame 222 provided on the conveyor frame 130, and a telescopic tray plate 224 provided on the telescopic tray drive frame 222. The telescopic tray plate 224 is laterally telescopically provided on the inner side of the conveyor frame 130 and located at the bottom of the side compartment plate. The telescopic tray plates 224 on both sides and the side compartment plates on both sides form a tray cavity for storing and loading circuit board products. When multiple stacked pallets are transferred to the bottom of the pallet cavity via the receiving and transfer mechanism 300, the pallets can be lifted into the pallet cavity by the lifting receiving platform 330. The two conveyor frames 130 can be driven to move closer to each other by the conveyor telescopic drive component 120, so that the side compartment plates 212 on the conveyor frames 130 limit the multiple pallets from both sides. Then, the telescopic partition plate 224 can be extended to the inside of the conveyor frame 130 by the telescopic partition drive frame 222 of the telescopic partition structure 220, so that the telescopic partition plates 224 on both sides support and limit the multiple pallets from the bottom of both sides, thereby confining the multiple pallets in the storage compartment 210. Then, the lifting receiving platform 330 and the receiving and transfer mechanism 300 are reset.

[0042] Furthermore, the telescopic tray-splitting drive frame 222 may include a telescopic drive base frame 2222 disposed on the outer side of the conveyor frame 130, a telescopic drive cylinder 2224 disposed on the telescopic drive base frame 2222, and an intermediate connecting frame 2226 connected to the telescopic drive cylinder 2224. The intermediate connecting frame 2226 is connected to the middle of the telescopic tray-splitting plate 224, and the two sides of the telescopic tray-splitting plate 224 are slidably connected to the telescopic drive base frame 2222. The telescopic drive cylinder 2224 can drive the intermediate connecting frame 2226 and the telescopic tray-splitting plate 224 connected thereto to telescopically move, so that the telescopic tray-splitting plate 224 extends out of the inner side of the conveyor frame 130, or retracts into the conveyor frame 130 (or retracts out of the outer side of the conveyor frame 130), so that the protruding end of the telescopic tray-splitting plate 224 supports and limits the bottom of the tray to prevent the tray in the storage compartment 210 from falling, or releases the support and limitation on the bottom of the tray to allow the tray in the storage compartment 210 to fall. Furthermore, by sliding both sides of the telescopic tray 224 onto the telescopic drive base 2222, the telescopic movement of the tray 224 is stable and reliable, and the support for the pallet is more stable. Additionally, the telescopic drive cylinder 2224 can be replaced with other telescopic drive structures.

[0043] In addition, such as Figures 5 to 6As shown, the lifting tray support 230 may include a lifting support drive motor 232 mounted on the equipment frame, a lifting support transmission component 234 connected to the lifting support drive motor 232, and a lifting support plate structure 236 mounted on the lifting support transmission component 234. The lifting support plate structure 236 is located between the two conveyor belt structures 140 and below the storage compartment 210. The lifting support drive motor 232 can drive the lifting support transmission component 234 to operate, causing the lifting support transmission component 234 to move the lifting support plate structure 236 up and down, so that the lifting support plate structure 236 can support and lift the pallets. By cooperating with the lifting tray support 230 and the telescopic tray structure 220, the pallets stored in the storage compartment 210 can be trayed and unloaded.

[0044] When it is necessary to separate and unload the pallets stored in the storage compartment 210, the lifting support drive motor 232 and the lifting support transmission component 234 can drive the lifting support plate structure 236 to the bottom of the storage compartment 210 to support the pallets at the bottom of the storage compartment 210; then, the telescopic separating drive frame 222 can drive the telescopic separating plate 224 to retract, so that the telescopic separating plate 224 releases the support of the pallets at the bottom of the storage compartment 210, allowing the pallets at the bottom of the storage compartment 210 to fall onto the lifting support plate structure 236; then, the lifting support drive motor 232 and the lifting support transmission component 234 can drive... The lifting support plate structure 236 and the pallet on it are lowered to a preset height (the height of one pallet). Then, the telescopic tray drive frame 222 drives the telescopic tray plate 224 to extend, so that the telescopic tray plate 224 supports the pallet at the bottom of the storage compartment 210 again. Then, the lifting support plate structure 236 and the pallet on it can be driven to continue to descend (to below the conveyor belt structure 140) by the lifting support drive motor 232 and the lifting support transmission component 234, so that the pallet on the lifting support plate structure 236 falls onto the two conveyor belt structures 140, and the pallet can be transported by the two conveyor belt structures 140.

[0045] Furthermore, the lifting support transmission component 234 may include a lifting screw transmission structure 2342 connected to the lifting support drive motor 232; and the lifting support plate structure 236 may include a support base plate 2362 connected to the lifting screw transmission structure 2342, a lifting guide frame 2364 on each side of the support base plate 2362, and a support top plate 2366 on each lifting guide frame 2364. The lifting support drive motor 232 can drive the lifting screw transmission structure 2342 to work, so that the lifting screw transmission structure 2342 drives the support base plate 2362 to move up and down, which can drive the lifting guide frames 2364 on both sides of the support base plate 2362 to move up and down, thereby driving the support top plates 2366 on the two lifting guide frames 2364 to move up and down, so that the two support top plates 2366 support and lift the pallet from the bottom of the storage compartment 210.

[0046] In addition, such as Figures 7 to 8 As shown, the lifting receiving platform 330 of the receiving and transplanting mechanism 300 may include a receiving base 332 slidably disposed on the transplanting base 310, a receiving lifting drive 334 disposed on the receiving base 332, and a receiving plate 336 disposed on the receiving lifting drive 334. A linear drive module 320 is connected to the receiving base 332 and is used to drive the receiving plate 336 to move to the outside of the two conveyor frames 130 for receiving materials. The receiving lifting drive 334 is used to drive the receiving plate 336 to move up and down to the bottom of the storage compartment 210. The linear drive module 320 drives the receiving base 332 and its receiving plate 336 to move linearly, causing the receiving plate 336 to extend to the outside of the tray conveying mechanism 100 to receive multiple stacked pallets (loaded with circuit board products) from other workstations. Then, the linear drive module 320 drives the receiving plate 336 and its multiple pallets to move to the inside of the tray conveying mechanism 100, positioning the multiple pallets below the storage compartment 210. Then, the receiving lifting drive 334 drives the receiving plate 336 and its multiple pallets to rise, lifting the multiple pallets into the storage compartment 210. Then, in conjunction with the telescopic tray separating structure 220, the multiple pallets are confined within the storage compartment 210.

[0047] Furthermore, the receiving lifting drive 334 may include an eccentric rotating structure 3342 disposed on the receiving base 332 and connected to the receiving plate 336, and multiple lifting receiving supports 3344 connected between the receiving base 332 and the receiving plate 336. The eccentric movement of the eccentric rotating structure 3342 allows for lifting and lowering of the receiving plate 336; moreover, the multiple lifting receiving supports 3344 assist in supporting and lifting the receiving plate 336. The eccentric rotating structure 3342 and the lifting receiving supports 3344 make the lifting support of the receiving lifting drive 334 for the receiving plate 336 more stable and reliable.

[0048] Furthermore, the eccentric rotation structure 3342 may include an eccentric drive motor 33422 mounted on the receiving base 332, a rotating shaft 33424 connected to the eccentric drive motor 33422, a plurality of first eccentric connecting rods 33426 mounted on the rotating shaft 33424, and a second eccentric connecting rod 33428 hinged to each of the first eccentric connecting rods 33426. Each second eccentric connecting rod 33428 is hinged to the bottom of the receiving plate 336. When the eccentric drive motor 33422 drives the rotating shaft 33424 to rotate, it can drive the first eccentric connecting rods 33426 fixed on the rotating shaft 33424 to rotate. When the first eccentric connecting rods 33426 rotate, they can drive the second eccentric connecting rods 33428 to rotate, and at the same time, they can also cause the second eccentric connecting rods 33428 to move up and down, thereby causing the second eccentric connecting rods 33428 to drive the receiving plate 336 to move up and down.

[0049] Furthermore, the lifting receiving support 3344 may include a receiving support seat 33442 disposed on the receiving base 332, and a lifting cylinder 33444, a lifting hydraulic cylinder, or a telescopic sleeve on each side of the receiving support seat 33442. The two lifting cylinders 33444, the lifting hydraulic cylinders, or the telescopic sleeves are respectively connected to the bottom sides of the receiving plate 336. The lifting cylinders 33444 and the lifting hydraulic cylinders can provide auxiliary support for the receiving plate 336 and the receiving base 332, and can also limit the movement of the receiving plate 336 vertically.

[0050] The circuit board feeding and conveying equipment 10 provided by this utility model can automatically receive, store, unload and convey pallets without manual feeding, which can greatly improve production efficiency, reduce labor costs and reduce repetitive manual labor, which is in line with the trend of automation in the manufacturing industry.
