Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for conveyor lines, specifically a conveyor line fixing device. Background Technology

[0002] In industrial production, pallets need to be transported to designated locations via conveyors, and then robotic arms perform subsequent operations such as precise palletizing.

[0003] In existing technologies, when pallets are transported on a conveyor line, there is a lack of effective fixing measures after the pallets reach the designated position. As a result, when the robotic arm performs palletizing operations, the unstable position of the pallets makes it impossible to accurately place the goods, which affects the accuracy and efficiency of palletizing and reduces production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a conveyor line fixing device to solve the problem mentioned in the background art of the lack of effective fixing measures after the pallet reaches the designated position, which affects the accurate stacking of the robot.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A conveyor line fixing device includes: a U-shaped frame, in which three sets of conveyor belts are driven and installed to transport a pallet; a placement plate is provided between the three sets of conveyor belts; two sets of placement plates are fixedly installed on the upper inner surface of the U-shaped frame; and four sets of guide frames are fitted on the outer surface of the U-shaped frame, with fastening mechanisms slidably installed on the outer surfaces of the four sets of guide frames.

[0007] Preferably, a barrier plate is fixedly installed on the upper surface of both sets of placement plates, so that the barrier plate can block the pallet being transported, allowing the fastening mechanism to accurately fasten to the outer surface of the pallet.

[0008] Preferably, the fastening mechanism includes a fastening frame, with crossbars fixedly installed on both upper ends of the fastening frame. Each set of crossbars has mounting plates fixedly installed at both ends. Each set of mounting plates has four sets of limiting wheels rotatably installed at one end. Each pair of opposing limiting wheels abuts against both ends of the guide frame, thereby allowing the fastening frame to slide on the outer surface of the four sets of guide frames via the limiting wheels.

[0009] Preferably, a linear module is fixedly installed between every two sets of guide frames. The moving block of the linear module is fixedly connected to the crossbar, so that the moving block of the linear module can drive the buckle frame to perform lifting and lowering operations.

[0010] Preferably, two sets of mating blocks are fixedly installed at both ends of the lower surface of the buckle frame, and an L-shaped clamp is rotatably installed between each pair of horizontally opposite mating blocks, the L-shaped clamp extending rotatably to one end of the inner side of the buckle frame.

[0011] Preferably, a torsion spring is fixedly connected inside the docking block, and the other end of the torsion spring is fixedly connected to one end of the L-shaped clamping plate, so that the torsion spring can apply a torsion force to the L-shaped clamping plate.

[0012] Preferably, a limiting plate is fixedly installed on the lower end of the outer surface of each docking block. The limiting plate can block the connecting plate, and the connecting plate is fixedly installed on one end of the lower surface of the L-shaped clamp.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Through the design of the conveyor belt, baffles, guide frame, and fastening mechanism, during the conveyor belt transport of pallets, the pallets are blocked by the baffles set between the conveyor belts, forcing them to stop at a set position. The position where the pallet is blocked is flush with the fastening mechanism that slides on the outer surface of the guide frame. Then, the fastening mechanism can be activated to descend horizontally and fasten to the outer surface of the pallet, thereby clamping and fixing the pallet and stabilizing it. Then, the robot arm can pick up the pallet from the top surface for precise stacking. By fastening the pallet inside, a reliable guarantee is provided for the robot arm's precise stacking, improving the accuracy and efficiency of stacking, and thus improving production efficiency.

[0015] 2. Through the design of the buckle frame, crossbar, limit wheels, linear module, L-shaped clamping plate, torsion spring, limit plate, and connecting plate, the pallet is blocked by the barrier plate, forcing it to stop in the set position. Then, the linear module can be activated to pull down the crossbar via the moving block, causing the buckle frame to move vertically downward. The limit wheels on the mounting plates on both sides of the buckle frame roll along the outer surface of the guide frame. With the advantages of low rolling friction resistance and high motion accuracy, the buckle frame is ensured to descend smoothly and vertically, avoiding the buckling position deviation caused by shaking. As the buckle frame moves downward, the L-shaped clamping plate rotatably installed inside the buckle frame will contact the edge of the pallet first. The pallet applies a counterforce to the L-shaped clamps, which overcomes the spring force of the torsion spring, causing the L-shaped clamps to rotate and open around the connecting block. The L-shaped clamps then spring onto both ends of the pallet using the torsional force applied by the torsion spring. At the same time, the buckle frame is also fitted onto the outer surface of the pallet, forming a three-dimensional surrounding buckle. Compared to single-sided or single-point fixing, this method can firmly clamp the pallet and effectively resist the effects of vibration and tilt during subsequent handling and stacking, preventing the pallet and goods from shifting or even falling, and ensuring stability during the gripping and holding process.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-3 This embodiment provides the following technical solution:

[0022] like Figure 1 As shown, a conveyor line fixing device includes: a U-shaped frame 1, with three sets of conveyor belts 101 internally mounted to transport pallets. Placement plates 102 are provided between the three sets of conveyor belts 101, and two sets of placement plates 102 are fixedly mounted on the upper inner surface of the U-shaped frame 1. Four sets of guide frames 104 are fitted onto the outer surface of the U-shaped frame 1, and fastening mechanisms 2 are slidably mounted on the outer surfaces of the four sets of guide frames 104. Barrier plates 103 are fixedly mounted on the upper surfaces of both sets of placement plates 102 to block the transported pallets, allowing the fastening mechanisms 2 to accurately fasten onto the outer surface of the pallets.

[0023] Through the design of the conveyor belt 101, the baffle plate 103, the guide frame 104, and the fastening mechanism 2, during the process of conveying the pallet by the conveyor belt 101, the pallet is blocked by the baffle plate 103 set between the conveyor belts 101, forcing it to stop at a set position. The position where the pallet is blocked is flush with the fastening mechanism 2 which is slidably installed on the outer surface of the guide frame 104. Then, the fastening mechanism 2 can be activated to descend horizontally and fasten to the outer surface of the pallet, thereby clamping and fixing the pallet and making the pallet stable. Then, the robot can pick up the pallet from the top surface for precise stacking. By fastening the pallet inside, a reliable guarantee is provided for the robot to stack accurately, improving the accuracy and efficiency of stacking, thereby improving production efficiency.

[0024] like Figures 2-3 As shown, the fastening mechanism 2 includes a fastening frame 201. Crossbars 202 are fixedly installed on the upper ends of both sides of the fastening frame 201. Mounting plates 203 are fixedly installed at both ends of each set of crossbars 202. Four sets of limiting wheels 204 are rotatably mounted on one end of each set of mounting plates 203. Each pair of opposing limiting wheels 204 abuts against both ends of the guide frame 104, allowing the fastening frame 201 to slide on the outer surface of the four sets of guide frames 104 via the limiting wheels 204. A linear module 205 is fixedly installed between each pair of guide frames 104. The moving block of the linear module 205 is fixedly connected to the crossbars 202, allowing the linear module 205 to move and drive the fastening frame 201 to perform lifting and lowering operations. Two sets of mating blocks 207 are fixedly installed at both ends of the lower surface of the buckle frame 201. An L-shaped clamping plate 206 is rotatably installed between each pair of laterally opposite mating blocks 207, and the L-shaped clamping plate 206 extends rotatably to one end of the inner side of the buckle frame 201. A torsion spring 209 is fixedly connected inside the mating block 207, and the other end of the torsion spring 209 is fixedly connected to one end of the L-shaped clamping plate 206, so that the torsion spring 209 can apply a torsional force to the L-shaped clamping plate 206. A limiting plate 208 is fixedly installed at the lower end of the outer surface of the mating block 207. The limiting plate 208 can block the connecting plate 210, which is fixedly installed at one end of the lower surface of the L-shaped clamping plate 206.

[0025] Through the design of the buckle frame 201, crossbar 202, limiting wheel 204, linear module 205, L-shaped clamp 206, torsion spring 209, limiting plate 208, and connecting plate 210, the tray is blocked by the barrier plate 103, forcing it to stay in the set position. Then, the linear module 205 can be activated to pull down the crossbar 202 via the moving block, causing the buckle frame 201 to move vertically downward. At the same time, the limiting wheels 204 on the mounting plates 203 on both sides of the buckle frame 201 roll along the outer surface of the guide frame 104. With the advantages of low rolling friction resistance and high motion accuracy, the buckle frame 201 is ensured to descend smoothly and vertically, avoiding the buckling position deviation caused by shaking. As the buckle frame 201 moves downward, the internal rotation of the buckle frame 201... The installed L-shaped clamp 206 will first contact the edge of the pallet, and the pallet can then exert a reverse force on the L-shaped clamp 206 to overcome the elastic force of the torsion spring 209, causing the L-shaped clamp 206 to rotate and open around the docking block 207. The L-shaped clamp 206 can then be clamped at both ends of the pallet by the torsional elastic force applied by the torsion spring 209. At this time, the buckle frame 201 will also be fitted onto the outer surface of the pallet, forming a three-dimensional surrounding buckle for the pallet. Compared with single-sided or single-point fixing, it can firmly clamp the pallet and effectively resist the effects of vibration and tilt during subsequent handling and stacking, preventing the pallet and goods from shifting or even falling, and ensuring stability during the gripping and clamping process.

[0026] Based on the above technical solution, the working steps of this solution are summarized as follows: During the conveyor belt 101's transport of the pallet, the pallet is blocked by the baffle plates 103 set between the conveyor belts 101, forcing it to stop at a set position. The blocked position of the pallet is flush with the buckle frame 201 slidably mounted on the outer surface of the guide frame 104. Then, the linear module 205 can be activated to drive the buckle frame 201 to move vertically downward by pulling down the crossbar 202 via the moving block. The limit wheels 204 on the mounting plates 203 on both sides of the buckle frame 201 roll along the outer surface of the guide frame 104, ensuring that the buckle frame 201 descends smoothly and vertically. As the buckle frame 201 moves downward, the L-shaped clamp 206 rotatably mounted inside the buckle frame 201 will first contact the edge of the pallet, and the pallet can then exert a reverse force on the L-shaped clamp 206 to overcome the torsion spring 209. The elastic force causes the L-shaped clamp 206 to rotate and open around the docking block 207. The L-shaped clamp 206 can then be clamped at both ends of the pallet by the torsional elastic force applied by the torsion spring 209. At this time, the buckle frame 201 will also be fitted onto the outer surface of the pallet, forming a three-dimensional surrounding buckle for the pallet. Compared with single-sided or single-point fixing, it can firmly clamp the pallet. Then, the robot arm can clamp the pallet from the top surface for precise stacking. The buckle frame 201 can then be lifted again by the linear module 205, and the L-shaped clamp 206, which is not touched by the pallet, can be twisted back to its original position by the torsion spring 209. During the twisting back to its original position, the L-shaped clamp 206 will be fixed in the current position by touching one end of the limiting plate 208 through the connecting plate 210 on the lower surface, so as to be fastened to the pallet for the next time.

[0027] In summary, this conveyor line fixing device allows the pallets to be secured within the locking frame 201 during the pallet clamping and stacking process, thus forming a three-dimensional surrounding clamping of the pallet. Compared to single-sided or single-point fixing, it can firmly clamp the pallet and effectively resist the effects of vibration and tilting during subsequent handling and stacking, preventing the pallet and goods from shifting or even falling, and ensuring stability during the gripping and holding process.
