Description

Technical Field

[0001] This utility model relates to the technical field of material handling devices, and in particular to a material handling device. Background Technology

[0002] Please see Figure 1 When the tray 100 is loaded with a large number of small products 200 (such as small soft-pack battery cells), the size of the picking slot 1001 that can be set on one side of the small product 200 is small, so it is difficult to manually pick out these small products 200. Moreover, the force required to pick them out is often large, which poses a risk of damaging the appearance of the products. In addition, manually picking out the small products 200 one by one also has the problem of low picking efficiency. Therefore, it is urgent to design a picking device to improve the efficiency of manually picking out a large number of small products 200 from the tray 100. Utility Model Content

[0003] This utility model provides a material handling device, which mainly solves the technical problem of how to improve the material handling efficiency of small products when they are difficult to manually remove.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A material handling device, comprising:

[0006] The suction plate has an internal air cavity and an external surface with at least one adsorption hole communicating with the air cavity.

[0007] The foot pedal valve is provided with an air inlet and a first air outlet and a second air outlet respectively connected to the air inlet. The air inlet is used to connect to an external air source. When the foot pedal valve is not pressed, the first air outlet is normally closed and the second air outlet is normally open. When the foot pedal valve is pressed, the first air outlet is open and the second air outlet is closed. The second air outlet is connected to the air chamber through an air pipe.

[0008] A vacuum generator includes an input end for air intake and an output end for generating negative pressure. The input end is connected to the first air outlet through an air pipe, and the output end is connected to the air chamber through an air pipe.

[0009] In one of the technical solutions, the material handling device includes a three-way connector, a first air pipe, a second air pipe, and a third air pipe;

[0010] The first air tube, the second air tube, and the third air tube are respectively connected to the three-way connector. The end of the first air tube away from the three-way connector is connected to the output end of the vacuum generator. The end of the second air tube away from the three-way connector is connected to the second air outlet. The end of the third air tube away from the three-way connector is connected to the air chamber.

[0011] In one of the technical solutions, a one-way throttle valve is installed along the path of the second air tube.

[0012] In one of the technical solutions, a filter is provided along the path of the third air tube.

[0013] In one of the technical solutions, the material handling device further includes a fixed base with screw holes and at least two pairs of elastic arms, which together clamp the filter.

[0014] In one of the technical solutions, the surface of the suction plate is provided with a plurality of suction holes, and each suction hole is equipped with a suction nozzle.

[0015] In one of the technical solutions, the suction plate has a bent and extended handle portion.

[0016] In one of the technical solutions, the foot valve includes a valve body, a pedal, and an elastic element;

[0017] The pedal is rotatably connected to the valve body and has a first rotational position and a second rotational position relative to the valve body. The elastic element is connected between the valve body and the pedal. The pedal is in the first rotational position due to the elastic force of the elastic element. The valve body is provided with the air inlet, the first air outlet and the second air outlet.

[0018] When the pedal is not pressed and is in the first rotating position, the pedal blocks the first air outlet but does not block the second air outlet;

[0019] When the pedal is pressed to the second rotation position, the pedal blocks the second air outlet but not the first air outlet.

[0020] Compared with the prior art, the material handling device provided by this utility model has at least the following beneficial effects:

[0021] Before using the material handling device in this solution, an external air source needs to be connected to the air inlet on the foot valve via an air hose. When the material handling device is handling material, the foot valve needs to be pressed, switching the first air outlet on the foot valve from a normally closed state to an open state. At the same time, the second air outlet on the foot valve switches from a normally open state to a closed state. At this time, the gas pumped by the external air source will enter the input end of the vacuum generator from the first air outlet, enabling the output end of the vacuum generator to generate negative pressure. This creates a negative pressure state in the air chamber inside the suction plate, allowing the suction plate to be used to pick up small products. After the small product is picked up, the foot can be removed from the foot valve, returning it to its unpressed state. At this time, the first air outlet automatically closes and the second air outlet opens. The gas pumped by the air source will then enter the air chamber from the second air outlet, releasing the negative pressure state in the air chamber. The small product that was originally picked up on the suction plate will then automatically fall onto the table.

[0022] The material handling device of this solution has the advantages of simple structure and simple operation. With this material handling device, the operator can quickly take out small products from the material tray by stepping on the foot valve. This can greatly improve the efficiency of picking up small products and also avoid damage to small products caused by forcefully prying them out. Attached Figure Description

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0038] Please refer to the following: Figures 2 to 5This utility model provides a material handling device, which mainly includes a suction plate 1, a foot valve 2, a vacuum generator 3, and several air pipes. The suction plate 1 is made of lightweight and non-deformable acetal material. An air chamber 11 is provided inside the suction plate 1, and at least one adsorption hole 12 connected to the air chamber 11 is provided on the outer surface of the suction plate 1. When the air chamber 11 is under negative pressure, the adsorption hole 12 can adsorb small products. The foot valve 2 is equipped with an air inlet 211, a first air outlet 212, and a second air outlet 213. The air inlet 211 is used to connect to an external air source. The first air outlet 212 and the second air outlet 213 are respectively connected to the air inlet 211. However, only one of the first air outlet 212 and the second air outlet 213 is in the open state, while the other is in the closed state. Specifically, when the foot valve 2 is not pressed, the first air outlet 212 is in the normally closed state and the second air outlet 213 is in the normally open state. When the foot valve 2 is pressed, the first air outlet 212 is in the open state and the second air outlet 213 is in the closed state. The second air outlet 213 is connected to the air chamber 11 mentioned above through an air pipe. The vacuum generator 3 is existing technology. The vacuum generator 3 includes an input end 31 and an output end 32. The input end 31 is connected to the first air outlet 212 mentioned above through an air pipe. When the first air outlet 212 is opened, the positive pressure gas from the gas source can enter the vacuum generator 3 from the input end 31. The vacuum generator 3 utilizes Bernoulli's principle to generate negative pressure at the output end 32 using positive pressure gas. The output end 32 is connected to the air chamber 11 mentioned above through an air pipe, so that the air chamber 11 can also generate negative pressure.

[0039] The following is a more detailed explanation of the usage process of the material handling device in this solution: Before using the material handling device, it is necessary to connect the external air source and the air inlet 211 on the foot valve 2 using an air pipe. When the material handling device is handling material, the foot valve 2 needs to be pressed to switch the first air outlet 212 on the foot valve 2 from the normally closed state to the open state. At the same time, the second air outlet 213 on the foot valve 2 is switched from the normally open state to the closed state. At this time, the gas pumped by the external air source will enter the input end 31 of the vacuum generator 3 from the first air outlet 212, so that the output end 32 of the vacuum generator 3 can generate negative pressure, thereby making the air chamber 11 in the suction plate 1 in a negative pressure state. At this time, the suction plate 1 can be used to adsorb small products. After the small product is sucked out, the foot can leave the foot pedal valve 2, so that the foot pedal valve 2 returns to the unpressed state. At this time, the first air outlet 212 is automatically closed and the second air outlet 213 is open. At this time, the gas pumped by the air source will enter the air chamber 11 from the second air outlet 213, so that the air chamber 11 is released from the negative pressure state. At this time, the small product that was originally adsorbed on the suction plate 1 will automatically fall onto the table.

[0040] Please refer to them again. Figures 2 to 5 The material handling device in this embodiment also includes a three-way connector 4, a first air pipe 5, a second air pipe 6, and a third air pipe 7. The three-way connector 4 has three holes for connecting air supply pipes, and the three holes are interconnected. The first air pipe 5, the second air pipe 6, and the third air pipe 7 are respectively connected to the three-way connector 4. The end of the first air pipe 5 away from the three-way connector 4 is connected to the output end 32 of the vacuum generator 3. The end of the second air pipe 6 away from the three-way connector 4 is connected to the second air outlet 213. The end of the third air pipe 7 away from the three-way connector 4 is connected to the air chamber 11. Specifically, when the foot pedal 2 is pressed, the gas pumped by the external air source will enter the input end 31 of the vacuum generator 3 from the first air outlet 212, so that the output end 32 of the vacuum generator 3 can generate negative pressure. Since the output end 32 of the vacuum generator 3 is connected to the air chamber 11 through the first air pipe 5 and the third air pipe 7, the air chamber 11 in the suction plate 1 can also be in a negative pressure state. When the foot leaves the foot pedal valve 2, the gas pumped by the air source will be output from the second air outlet 213 and enter the air chamber 11 sequentially along the second air pipe 6 and the third air pipe 7, thereby releasing the negative pressure state of the air chamber 11. As can be seen from the above, the formation of negative pressure in the suction plate 1 and the outward pressure relief both affect the third air pipe 7. By adopting the above design, it is beneficial to reduce the number of air pipes used. At the same time, only one air connector connected to the third air pipe 7 needs to be set on the suction plate 1, thereby making the overall structure of the material handling device simpler and reducing the manufacturing cost of the material handling device.

[0041] Please see Figure 2 The material handling device in this embodiment also includes a one-way throttle valve 8. The one-way throttle valve 8 is disposed on the path of the second air pipe 6. The one-way throttle valve 8 can adjust the flow rate of the gas flowing out from the second air outlet 213, thereby helping to control the pressure of the suction plate 1 within a suitable range, preventing the pressure relief pressure from being too high and causing small products to be blown out by strong pressure, and also preventing the pressure relief pressure from being too low and causing small products to be difficult to detach from the suction plate 1.

[0042] Please see Figure 2 The material handling device in this embodiment also includes a filter 9, which is disposed on the path of the third air pipe 7. The filter 9 is used to filter impurities in the gas flowing out from the second air outlet 213, preventing foreign objects from entering the air chamber 11 inside the suction plate 1, and also preventing small products from being impacted by foreign objects during the pressure relief process, thereby ensuring that the suction plate 1 will not damage the appearance of small products during the pressure relief process.

[0043] Please refer to the following: Figure 2 and Figure 6The material handling device in this embodiment also includes a fixing base 10, which has screw holes 101 and at least two pairs of elastic arms 102. The fixing base 10 can be fixed in a designated position by passing screws through the screw holes 101. The filter 9 is fixed in a designated position by snapping it between the two pairs of elastic arms 102, so that the two pairs of elastic arms 102 together clamp the filter 9.

[0044] Please refer to the following: Figure 2 , Figure 4 and Figure 5 The suction plate 1 has multiple suction holes 12 as described above on its surface, and each suction hole 12 is equipped with a suction nozzle 14. This design allows the suction plate 1 to reliably pick up multiple small products simultaneously, thereby improving the efficiency of picking up small products. In addition, the suction plate 1 also has a bent and extended handle 13. This handle 13 design allows operators to more easily hold the suction plate 1 for picking up materials, which also helps to improve the efficiency of picking up small products.

[0045] Please refer to the following: Figure 2 and Figure 3 This section provides a more detailed description of the structure of the foot valve 2 described above. The foot valve 2 can be understood as including at least a valve body 21, a pedal 22, and an elastic element (not shown in the figure). The valve body 21 is provided with the aforementioned air inlet 211, a first air outlet 212, and a second air outlet 213. The pedal 22 and the valve body 21 are rotatably connected. The elastic element connects the valve body 21 and the pedal 22. The elastic element can be a torsion spring or a spring. Let the position where the pedal 22 springs upward relative to the valve body 21 under the elastic force of the elastic element be the first rotational position, and let the position where the pedal 22 is pressed be the second rotational position. Figure 2 and Figure 3 The pedals 22 shown are all in the first rotating position. Specifically, when the pedal 22 is not pressed and is in the first rotating position, the pedal 22 blocks the first air outlet 212 but not the second air outlet 213. At this time, the air chamber 11 in the suction plate 1 is under positive pressure. When the pedal 22 is pressed to the second rotating position, the pedal 22 blocks the second air outlet 213 but not the first air outlet 212. At this time, the air chamber 11 in the suction plate 1 is under negative pressure. It can be seen that by designing the foot valve 2 as described above, the operator can control the suction plate 1 to suck up or depressurize by controlling the foot valve 2, thereby improving the efficiency of the operator in picking up small products.

[0046] In summary, the material handling device of this solution has the advantages of simple structure and simple operation. With the material handling device of this solution, small products can be quickly removed from the material tray by manually stepping on the foot valve 2. This is beneficial to greatly improve the efficiency of material handling of small products, and can also avoid damage to small products caused by forceful prying.

[0047] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
