Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and in particular to a material clamp and a multi-functional palletizer. Background Technology

[0002] When a palletizer is working, the clamps need to be moved to the material location, gripped and secured by the clamps, and then transferred and palletized. Current clamps typically can only transfer and palletize a single type of material. If multiple different materials need to be transferred simultaneously, multiple clamps are required, each with its own moving mechanism, resulting in a complex overall structure and high production costs. Therefore, there is an urgent need for a clamp capable of handling diverse materials, thereby simplifying the overall structure. Utility Model Content

[0003] The purpose of this utility model is to provide a material clamp and a multi-functional palletizer to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0006] This technical solution has at least the following beneficial effects: The base frame is used to connect to the mobile device of the external device. During operation, the mobile device of the external device drives the base frame to move to the material to be clamped. The material can be moved by either the picking component or the clamping component. Specifically, when the picking component is used to move the material, the left and right jaws rotate towards each other, so that the left and right jaws move up to above the picking end. At this time, the picking end can approach the material to remove the material. When the clamping component is used to move the material, the left and right jaws rotate away from each other, so that the left and right jaws protrude downward from the picking end. When they move closer to the material, the left and right jaws move closer to each other again, thereby clamping the left and right sides of the material to remove the material. In this way, the picking component and the clamping component can be used to clamp different materials, enriching the overall functionality, simplifying the structure for moving and stacking different materials, reducing equipment manufacturing costs, and making it more practical.

[0007] As a further improvement to the above technical solution, the left clamping part includes a first telescopic drive, a first rotating shaft and a first transmission block. The first rotating shaft is rotatably connected to the base frame. One end of the first transmission block is connected to the first rotating shaft. One end of the first telescopic drive is rotatably connected to the base frame. The other end of the first telescopic drive is rotatably connected to the other end of the first transmission block. The left gripper is connected to both ends of the first rotating shaft.

One end of the second telescopic drive is rotatably connected to the base frame. The other end of the second telescopic drive is rotatably connected to the other end of the second transmission block. The two ends of the second rotating shaft are respectively connected to the right gripper.

[0009] As a further improvement to the above technical solution, the two left grippers and the two right grippers are staggered relative to each other in the front-back direction.

[0010] As a further improvement to the above technical solution, the bottom of the left gripper is bent to the right to form a left hook, and the bottom of the right gripper is bent to the left to form a right hook.

[0011] As a further improvement to the above technical solution, the top side of the left hook is provided with a plurality of first serrations, and the top side of the right hook is provided with a plurality of second serrations.

[0012] As a further improvement to the above technical solution, the material handling component includes a negative pressure box connected to the bottom side of the base frame, a negative pressure pump connected to the negative pressure box, and a plurality of vacuum suction cups connected to the bottom side of the negative pressure box. The plurality of vacuum suction cups are respectively connected to the interior of the negative pressure box, and the plurality of vacuum suction cups respectively form a plurality of material handling ends.

[0013] As a further improvement to the above technical solution, multiple material handling components are provided on the bottom side of the base frame.

[0014] A multi-functional palletizer includes a robotic arm and the aforementioned material clamps, wherein the robotic arm is driven to the base frame.

[0015] This technical solution has at least the following beneficial effects: During operation, the robotic arm drives the base frame to move to the material to be gripped.

[0028] Reference Figure 1 and Figure 2A material clamp includes a base frame 100, a material picking component, and a clamping component. The material picking component is disposed on the bottom side of the base frame 100 and has a downwardly facing material picking end. The clamping component includes a left clamping part and a right clamping part disposed on the base frame 100. The left clamping part has a rotatable left jaw 211, and the right clamping part has a rotatable right jaw 221. The left jaw 211 and the right jaw 221 can rotate in a direction away from each other and protrude downward from the material picking end. The left jaw 211 and the right jaw 221 can rotate in a direction closer to each other and move upward above the material picking end.

[0029] As described above, the base frame 100 is used to connect to the mobile device of the peripheral device. During operation, the mobile device of the peripheral device drives the base frame 100 to move to the material to be gripped. The material can be moved using either the material-grabbing component or the material-clamping component. Specifically, when the material-grabbing component is used, the left gripper 211 and the right gripper 221 rotate towards each other, causing the left gripper 211 and the right gripper 221 to move upwards above the material-grabbing end. At this time, the material-grabbing end can approach the material to remove it. When the material-clamping component is used... When the component picks up materials, the left gripper 211 and the right gripper 221 rotate in a direction away from each other, causing the left gripper 211 and the right gripper 221 to protrude downwards from the picking end. When they move closer to the material, the left gripper 211 and the right gripper 221 move closer to each other, thereby clamping the left and right sides of the material to pick it up. In this way, the picking component and the clamping component can be selected to clamp different materials, enriching the overall functions, simplifying the structure for picking up and stacking different materials, reducing equipment manufacturing costs, and making it more practical.

[0030] The left clamping section has a drive source that can drive the left gripper 211 to reciprocate. For example, the left clamping section includes a rotary drive mounted on the base frame 100. The rotary drive is connected to the left gripper 211. The rotary drive can be a motor or a rotary cylinder, etc., to drive the left gripper 211 to rotate directly, thereby adjusting the position of the left gripper 211 and picking up and putting away materials. In addition, the left clamping section can also use a telescopic drive to drive the left gripper 211 to rotate. Specifically, the left clamping section includes a first telescopic drive 212, a first rotating shaft 213, and a first transmission block 214. The first rotating shaft 212... 3. Rotatably connected to the base frame 100, one end of the first transmission block 214 is connected to the first rotating shaft 213, one end of the first telescopic drive 212 is rotatably connected to the base frame 100, and the other end of the first telescopic drive 212 is rotatably connected to the other end of the first transmission block 214. The first telescopic drive 212 can be driven by a cylinder, electric screw or hydraulic cylinder, etc. The two ends of the first rotating shaft 213 are respectively connected to the left gripper 211. Naturally, the rotation axis of the first rotating shaft 213 and the rotation axes of the two ends of the first telescopic drive 212 both extend in the front-back direction.

[0031] In this embodiment, left grippers 211 are connected to both ends of the first rotating shaft 213. At this time, the two left grippers 211 are located on both sides of the base frame 100. When it is necessary to drive the left grippers 211 to rotate, the extension or retraction of the first telescopic drive 212 is controlled, and the first rotating shaft 213 is driven to rotate through the first transmission block 214, so that the left grippers 211 connected to both ends of the first rotating shaft 213 rotate closer to the right gripper 221 or rotate away from the right gripper 221.

[0032] Similarly, the right clamping section has a drive source that can drive the right gripper 221 to reciprocate. For example, the right clamping section includes a rotary drive mounted on the base frame 100. The rotary drive is connected to the right gripper 221. The rotary drive can be a motor or a rotary cylinder, etc., to directly drive the right gripper 221 to rotate, thereby adjusting the position of the right gripper 221 and picking up and putting away materials. In addition, the right clamping section can also use a telescopic drive to drive the right gripper 221 to rotate. Specifically, the right clamping section includes a second telescopic drive 222, a second rotating shaft 223, and a second transmission block 224. The second rotating shaft... 223 is rotatably connected to the base frame 100. One end of the second transmission block 224 is connected to the second rotating shaft 223. One end of the second telescopic drive 222 is rotatably connected to the base frame 100. The other end of the second telescopic drive 222 is rotatably connected to the other end of the second transmission block 224. The second telescopic drive 222 can be driven by a cylinder, an electric lead screw, or a hydraulic cylinder. The two ends of the second rotating shaft 223 are respectively connected to the right gripper 221. Naturally, the rotation axis of the second rotating shaft 223 and the rotation axes of the two ends of the second telescopic drive 222 both extend in the front-back direction.

[0033] In this embodiment, right grippers 221 are connected to both ends of the second rotating shaft 223. At this time, the two right grippers 221 are located on both sides of the base frame 100. When it is necessary to drive the right grippers 221 to rotate, the extension or retraction of the second telescopic drive 222 is controlled, and the second rotating shaft 223 is driven to rotate through the second transmission block 224, so that the right grippers 221 connected to both ends of the second rotating shaft 223 rotate closer to the right gripper 221 or rotate away from the right gripper 221.

[0034] In the above embodiment, the two left grippers 211 and the two right grippers 221 can face each other directly. At this time, the lengths of the left grippers 211 and the right grippers 221 cannot be designed to be too long, thus avoiding interference when they approach each other. To extend the length of the left grippers 211 and the right grippers 221 and improve their applicability to material gripping, in this embodiment, the two left grippers 211 and the two right grippers 221 are staggered relative to each other in the front-back direction. When the two left grippers 211 and the two right grippers 221 rotate to approach each other, they are staggered to avoid mutual interference and collision.

[0035] To improve the stability of the left gripper 211 and right gripper 221 when handling items, in this embodiment, the bottom of the left gripper 211 is bent to the right to form a left hook 215, and the bottom of the right gripper 221 is bent to the left to form a right hook 225. When the left gripper 211 and right gripper 221 approach each other to clamp the material, the left hook 215 and right hook 225 can be inserted into the preset holes on the left and right sides of the material, respectively, thereby clamping and positioning the material on both sides. At this time, the left hook 215 and right hook 225 can be used to hook and position the material on the left and right sides, which can improve the stability of clamping the material and effectively prevent the material from falling.

[0036] Furthermore, the top side of the left hook 215 is provided with multiple first serrations 216, and the top side of the right hook 225 is provided with multiple second serrations 226. When the left hook 215 and the right hook 225 are inserted into the preset holes on the left and right sides of the material, the first serrations 216 on the left hook 215 and the second serrations 226 on the right hook 225 can be locked onto the edges of the material, effectively preventing the left hook 215 and the right hook 225 from slipping relative to the material, and further improving the stability of material clamping.

[0037] The material handling component can also use a clamping method to pick up and place materials. However, unlike the clamping component, the size of the clamp formed by the material handling component is different, allowing it to handle different materials. In this embodiment, the material handling component uses a different handling method than the clamping component to further improve overall versatility. Specifically, the material handling component includes a negative pressure box 310 connected to the bottom side of the base frame 100, a negative pressure pump connected to the negative pressure box 310, and multiple vacuum suction cups 320 connected to the bottom side of the negative pressure box 310. The multiple vacuum suction cups 320 are interconnected with the interior of the negative pressure box 310, and each vacuum suction cup 320 forms a multiple material handling end. In use, the negative pressure pump evacuates the negative pressure box 310, creating negative pressure on the multiple vacuum suction cups 320 connected to the negative pressure box 310. At this time, the multiple vacuum suction cups 320 act as multiple material handling ends, adsorbing the material under negative pressure when they approach it, thereby achieving the picking up and placing of the material.

[0038] In the above embodiments, there may be only one material-grabbing component. When it is necessary to adsorb materials with a large adsorption area or various shapes, multiple material-grabbing components can be selected. Specifically, multiple material-grabbing components are provided on the bottom side of the base frame 100. Multiple material-grabbing components can increase the adsorption range of materials, thereby improving the stability of material removal. In practical applications, the negative pressure box 310 can be disassembled from the base frame 100, thereby improving the flexibility of use.

[0039] like Figure 3As shown, a multi-functional palletizer includes a robotic arm 400 and the aforementioned material clamps, wherein the robotic arm 400 is connected to the base frame 100 via a transmission.

[0040] In this multi-functional palletizer, during operation, the robotic arm 400 drives the base frame 100 to move to the material to be clamped. The material can be moved by either the picking component or the clamping component, thus enabling the clamping of different materials, enriching the overall functionality, simplifying the structure for moving and stacking different materials, reducing equipment manufacturing costs, and making it more practical.

[0041] This utility model also includes a pallet conveyor 500, a product conveyor 600, and a pallet storage rack 700 disposed beside the robotic arm 400. The robotic arm 400 can drive the material clamp to move between the pallet conveyor 500, the product conveyor 600, and the pallet storage rack 700. In practical applications, the robotic arm 400 can be a six-degree-of-freedom manipulator. Both the pallet conveyor 500 and the product conveyor 600 are used to transport materials in a straight line and can be belt conveyors, roller conveyors, etc. In use, the pallet storage rack 700 stores empty pallets, the pallet conveyor 500 is used to transport pallets with products, and the product conveyor 600 is used to transport products to be stacked. Naturally, both can also transport different materials according to usage needs. The robotic arm 400 moves the material clamp to the pallet storage rack 700, removes the empty pallet and places it on the pallet conveyor 500. Then the robotic arm 400 moves the material clamp to the product conveyor 600, removes the product delivered by the product conveyor 600 and places it on the pallet. This process of picking up and placing products is repeated to stack the products on the pallet.
