[0037] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly. Those skilled in the art can reasonably determine the specific meaning of these terms in this utility model in conjunction with the specific content of the technical solution.

[0038] refer to Figures 1 to 8 This utility model provides an automatic feeding device, including a workbench 100 and a conveyor belt mechanism 110. The conveyor belt mechanism 110 is disposed on the workbench 100 and has a feeding position and a picking position. It also includes a feeding component 200 and a sliding component 300.

[0039] The feeding assembly 200 includes a feeding component 210, a limiting component 220, and an extension rod 230. The bottom end of the extension rod 230 is connected to the limiting component 220, and the feeding component 210 is movably connected to the limiting component 220. The feeding component 210 is used to grip materials. The sliding component 300 can drive the feeding assembly 200 to slide so that the materials can be transferred.

[0040] It should be understood that the sliding component 300 can drive the feeding component 200 to move. When the feeding component 210 moves into the container, the feeding component 210 grabs the material in the container, and then the sliding component 300 starts to move the material again.

[0041] It should be noted that the loading component 210 adopts a magnetic loading method. When the loading component 210 approaches the material, the material can be attracted to the loading component 210, thereby replacing the traditional robotic arm that grips the material. This avoids the problem of excessive gripping force from the robotic arm, which can easily damage the material. In some embodiments, the loading component 210 can be an electromagnet. When the circuit is on, the electromagnet is magnetic and is used by the loading component 210 to transfer the material from the container to the loading position. When the circuit is off, the electromagnet loses its magnetism, allowing the material on the loading component 210 to fall onto the conveyor belt mechanism 110. The loading component 210 is movably connected to the limiting component 220, allowing the loading component 210 to float up and down and swing when in contact with the material, reducing the pressure exerted by the loading component 210 on the material and preventing damage to the material.

[0042] According to the automatic feeding device provided in this embodiment of the present utility model, the sliding component 300 includes a worktable 100, a conveyor belt mechanism 110, a sliding seat 310, a slide rail 320, and a robotic arm 330. The conveyor belt mechanism 110 is disposed on the worktable 100 and has a feeding position and a picking position. The slide rail 320 is disposed corresponding to the feeding position and is fixed to the worktable 100 in a horizontal state. The sliding seat 310 is connected to the robotic arm 330, and the robotic arm 330 is connected to the assembly plate 240. The sliding seat 310 can slide along the slide rail 320, and the robotic arm 330 can rise and fall relative to the sliding seat 310.

[0043] In this embodiment, the loading position and the unloading position do not overlap. In other embodiments, the loading position and the unloading position may overlap, and this is not a limitation. The loading component 200 can transfer materials from inside the container to the loading position of the conveyor belt mechanism 110, and the conveyor belt mechanism 110 can transport the materials from the loading position to the unloading position. The loading component 210 grabs the materials inside the container, and then the sliding component 300 moves the loading component 210 back to the loading position so that the materials on the loading component 210 are placed on the conveyor belt mechanism 110, and then the conveyor belt mechanism 110 transports the materials from the loading position to the unloading position.

[0044] It should be understood that the slide rail 320 is fixed horizontally to the worktable 100. Through an external drive device, the sliding seat 310 can slide horizontally along the slide rail 320, and the robotic arm 330 slides in cooperation with the sliding seat 310. The robotic arm 330 can rise and fall relative to the sliding seat 310. The sliding seat 310 can limit and stabilize the robotic arm 330. The bottom end of the robotic arm 330 is connected to the assembly plate 240. The sliding seat 310 slides along the slide rail 320, driving the robotic arm 330 to slide above the container. The robotic arm 330 descends, allowing the loading component 210 to extend into the container and absorb the materials stacked inside. Then, the robotic arm 330 rises, and the sliding seat 310 slides along the slide rail 320, placing the materials at the loading position of the conveyor belt mechanism 110. The conveyor belt mechanism 110 transports the materials from the loading position to the docking position.

[0045] According to the automatic feeding device provided in the embodiment of this utility model, the feeding component 210 has a limiting hole 211 and a limiting groove 212, and the limiting hole 211 and the limiting groove 212 are connected; the limiting component 220 includes a first limiting block 221, a second limiting block 222 and a connecting rod 223, the first limiting block 221 is connected to the extension rod 230, one end of the connecting rod 223 is connected to the first limiting block 221 and the other end is connected to the second limiting block 222, and the connecting rod 223 is clearance-fitted with the limiting hole 211, and the second limiting block 222 is located in the limiting groove 212.

[0046] It should be understood that the top of the feeding component 210 is limited by the first limiting block 221, and the bottom of the feeding component 210 is limited by the second limiting block 222. The feeding component 210 floats up and down between the first limiting block 221 and the second limiting block 222. An extension connecting rod 223 is provided between the first limiting block 221 and the second limiting block 222. The diameter of the connecting rod 223 is smaller than the diameter of the limiting hole 211, and the height of the connecting rod 223 is greater than the height of the limiting hole 211, so that the feeding component 210 can rise and fall along the connecting rod 223, and the feeding component 210 can swing at a suitable angle to avoid damaging the material. The second limiting block 222 is located in the limiting groove 212, and the height of the second limiting block 222 is smaller than the height of the limiting groove 212. When the feeder 210 rises to its highest point, its top edge abuts against the first limiting block 221; when the feeder 210 falls to its lowest point, the top edge of the second limiting block 222 abuts against the top wall of the limiting groove 212, and the second limiting block 222 can only move within the limiting groove 212. Thus, when the sliding assembly 300 drives the feeder 210 to contact the material, the feeder 210 can adaptively float and swing, avoiding excessive pressure that could damage the material.

[0047] According to the automatic feeding device provided in this embodiment of the present utility model, the feeding component 200 includes an assembly plate 240, which is connected to an extension rod 230; there are multiple extension rods 230 and limiting members 220, with multiple extension rods 230 being equally spaced along the length direction of the assembly plate 240, and each extension rod 230 corresponding to a limiting member 220; there are multiple limiting holes 211 and limiting grooves 212, with each limiting hole 211 corresponding to a connecting rod 223, and each limiting groove 212 corresponding to a second limiting block 222.

[0048] It should be understood that, in this embodiment, the assembly plate 240 is used to install multiple extension rods 230. The extension rods 230 are symmetrically arranged at both ends of the assembly plate 240, and each extension rod 230 is equally spaced along the length direction of the assembly plate 240. Each extension rod 230 corresponds to a limiting member 220. In this embodiment, the length direction of the feeding member 210 is perpendicular to the conveying direction of the conveyor belt mechanism 110. Workers neatly stack materials in the container, with the stacking method adapted to the feeding member 210. When the sliding component 300 drives the assembly plate 240 to slide into the container, multiple materials can be adsorbed by the multiple feeding members 210, thereby transferring multiple materials from the container to the conveyor belt mechanism 110. The sliding component 300 can complete the transfer of multiple materials in one operation, increasing work efficiency.

[0049] The automatic feeding device provided according to the embodiment of the present utility model also includes a dropping component 400. The dropping component 400 is set corresponding to the feeding position. The dropping component 400 includes a support frame 410, a telescopic drive component 420 and a dropping plate 430. The support frame 410 is set on one side of the conveyor belt mechanism 110. The telescopic drive component 420 is fixed to the support frame 410 and drives the dropping plate 430.

[0050] In this embodiment, there are two sets of material feeding components 400. The two sets of material feeding mechanisms operate in the same state and are symmetrically arranged on both sides of the conveyor belt mechanism 110. The support frame 410 is fixed to the conveyor belt mechanism 110. The material feeding plate 430 is arranged corresponding to the feeding component 210. There is a clearance space between the material feeding plate 430 and the feeding component 210. When the material feeding plate 430 descends and comes into contact with the material adsorbed on the feeding component 210, the material can fall onto the conveyor belt mechanism 110, and the material feeding plate 430 will not damage the feeding component 210. The telescopic drive component 420 can drive the material feeding plate 430 to rise and fall, so that the material feeding plate 430 comes into contact with or separates from the material.

[0051] According to the automatic feeding device provided in the embodiment of this utility model, the unloading component 400 further includes a first sensor 440, which is disposed on the side of the conveyor belt mechanism 110, and is disposed corresponding to the feeding position. The first sensor 440 is signal connected to the telescopic drive component 420.

[0052] It should be noted that the sensing direction of the first sensor 440 is towards the conveying surface of the conveyor belt mechanism 110. The first sensor 440 is set to the loading position and is used to monitor whether there is material at the loading position of the conveyor belt mechanism 110. When the first sensor 440 detects that there is no material at the loading position of the conveyor belt mechanism 110, the telescopic drive member 420 drives the dropping plate 430 to descend so that the dropping plate 430 abuts against the material adsorbed on the loading member 210, so that the material falls from the loading member 210 to the conveyor belt mechanism 110. When the first sensor 440 detects that there is material at the loading position of the conveyor belt mechanism 110, the dropping plate 430 stops in its original position to prevent the material from piling up on the conveyor belt mechanism 110. When the conveyor belt mechanism 110 transfers the material to a point where the first sensor 440 can no longer detect it, it indicates that there is no material at the loading position, and at this time the telescopic drive member 420 can start to operate.

[0053] The automatic feeding device provided according to the embodiment of the present utility model also includes a material blocking component 500. The material blocking component 500 is set corresponding to the material picking position and includes a telescopic rod 510 and a baffle 520. The telescopic rod 510 is set on one side of the conveyor belt assembly and is connected to the baffle 520. The telescopic rod 510 can drive the baffle 520 to approach or move away from the conveying surface of the conveyor belt mechanism 110 so that the baffle 520 blocks the material.

[0054] It should be noted that the length direction of the baffle 520 is perpendicular to the conveyor belt's conveying direction, and the telescopic rod 510 is extendable and retractable, allowing the baffle 520 to rise and fall. When the baffle 520 descends below the top surface of the material, it can block the material at the picking position, preventing it from falling onto the conveyor belt mechanism 110 and causing damage if the material is not picked up in time. Furthermore, the extension length of the telescopic rod 510 is adjustable, allowing the baffle 520 to block stacked materials.

[0055] According to the automatic feeding device provided in the embodiment of this utility model, the material blocking assembly 500 further includes a guide rod 530 and a slider 540. The guide rod 530 is disposed on one side of the conveyor belt assembly, the slider 540 is slidably engaged with the guide rod 530, and the slider 540 is connected to the baffle 520.

[0056] It should be understood that the guide rod 530 is fixed to one side of the conveyor belt, the slider 540 can move up and down along the height direction of the guide rod 530, and the slider 540 is connected to the baffle 520. The guide rod 530 can limit the sliding of the slider 540 so that the slider 540 does not deviate or shake when it is raised and lowered, making the raising and lowering of the baffle 520 smoother and more reliable.

[0057] According to the automatic feeding device provided in the embodiment of this utility model, the material blocking component 500 includes a lifting drive component 550 and an adsorption plate 560. The lifting drive component 550 is disposed on the worktable 100 and connected to the adsorption plate 560. The lifting drive component 550 can drive the adsorption plate 560 to rise and fall so that the adsorption plate 560 can approach or move away from the conveying surface of the conveyor belt mechanism 110.

[0058] It should be understood that in this embodiment, the height of the adsorption plate 560 is always lower than the conveying surface of the conveyor belt mechanism 110, and the lifting drive 550 can drive the adsorption plate 560 closer to the conveying surface of the conveyor belt mechanism 110. The magnetic force of the adsorption plate 560 is adjusted to an appropriate size; when materials accumulate at the picking position of the conveyor belt mechanism 110, the adsorption plate 560 moves closer to the conveying surface of the conveyor belt mechanism 110 so that the adsorption plate 560 adsorbs the lower-height materials, causing the higher-height materials to fall onto the conveyor belt mechanism 110, thus avoiding material accumulation. In another embodiment, the height of the adsorption plate 560 can always be higher than the conveying surface of the conveyor belt mechanism 110, and the adsorption plate 560 is used to adsorb materials at higher heights.

[0059] According to the automatic feeding device provided in the embodiment of this utility model, the material blocking component 500 further includes a second sensor 570. The second sensor 570 is disposed on the side of the conveyor belt mechanism 110. The second sensor 570 is disposed corresponding to the material picking position. The second sensor 570 is signal connected to the lifting drive component 550 and the telescopic rod 510.

[0060] It should be understood that, in this embodiment, taking a furniture slide rail as an example, the furniture slide rail has a grooved surface and a top surface. The sensing end of the second sensor 570 faces the conveying surface of the conveyor belt mechanism 110. When the top surfaces of two furniture slide rails are stacked together, due to the height difference from a single furniture slide rail, when the second sensor 570 detects that there is a stack of furniture slide rails at the material pick-up position of the conveyor belt mechanism 110, the telescopic rod 510 extends, allowing the baffle 520 to block the stacked furniture slide rails. At the same time, the lifting drive component 550 extends, allowing the suction plate 560 to hold the furniture slide rail located below, so that the furniture slide rail located above falls onto the conveyor belt mechanism 110. When the second sensor 570 senses that there is material that has not been picked up at the unloading position, the telescopic rod 510 extends further, allowing the baffle 520 to block the material, preventing the material from falling due to untimely manual material pick-up.
