[0013] The lower end of the material receiving cylinder is connected to an adjusting cylinder, which can move up and down to adjust the width of the gap, thereby making this invention applicable to workpieces of different thicknesses.

[0014] The adjusting cylinder and the receiving cylinder are connected by a thread, and the height of the adjusting cylinder can be easily adjusted by simply turning the adjusting cylinder.

[0015] The top of the material receiving cylinder is provided with several auxiliary rods spaced apart circumferentially, and the auxiliary rods are arranged vertically.

[0036] Example

[0037] like Figure 1 As shown, this embodiment discloses a sheet punching and loading mechanism, which includes: a platform 1, an air pump, a material receiving cylinder 4, and a driving mechanism.

[0038] The platform 1 has a workpiece placement position. During punching, the workpiece 14 is placed on the workpiece placement position, and a through hole is punched into the workpiece 14 at the workpiece placement position. Additionally, the platform 1 has a clearance hole 11 located at the center of the workpiece placement position. During punching, the punch head of the stamping equipment above the platform 1 is vertically aligned with the clearance hole 11. When the punch head strikes downwards, a through hole is punched into the workpiece 14 corresponding to the clearance hole 11. This clearance hole 11 is a common feature in traditional stamping equipment and will not be elaborated further. In other words, the platform 1 can also be considered as the stamping platform of the stamping equipment, with the punch head (not shown in the figure) located directly above the workpiece placement position.

[0039] In addition, air jet holes 10 are provided on the carrier 1, and the air jet holes 10 are located at the edge of the workpiece placement position on the carrier 1. The air outlet end of the air pump is connected to the air jet holes 10. Specifically, when setting up, the air supply joint of the air pump can be screwed onto the air jet holes 10 from the lower surface of the carrier 1 by means of threaded connection. When the air pump is started, gas is instantly ejected upward from the air jet holes 10.

[0040] The material receiving cylinder 4 is installed on the carrier 1 through a support frame 7 and is used for placing the workpiece 14. The sheet punching loading and unloading mechanism of the present application is applicable to punching of sheets with different shapes, such as circular sheets, square sheets, etc. The shape of the material receiving cylinder 4 can be set to a shape matching the shape of the sheet. For example, when the sheet is square, the shape of the material receiving cylinder 4 can be set to a cube shape, and when the sheet is circular, the material receiving cylinder 4 can be set to a cylindrical shape. In this embodiment, the sheet is taken as an example of a circular sheet, as Figure 1 shown.

[0041] When installing the material receiving cylinder 4, the installation height of the material receiving cylinder 4 needs to be controlled so that a gap is formed between the lower end of the material receiving cylinder 4 and the upper surface of the carrier 1. When the width of this gap is L, L needs to meet the following conditions: H < L < 2H, where H is the thickness of the workpiece 14. This can ensure that only the lowermost workpiece 14 is pushed out of this gap.

[0042] The driving mechanism is arranged on the carrier 1 and is used for pushing the workpiece 14 falling from the material receiving cylinder 4 to the workpiece placement position on the carrier 1. Specifically, the driving mechanism includes a driver 2 arranged on the carrier 1 and a pushing plate 3 connected to the driver 2. The thickness of the pushing plate 3 is slightly less than the thickness of the workpiece 14 to ensure that the pushing plate 3 can pass through the gap between the material receiving cylinder 4 and the carrier 1 and push the workpiece 14 to the workpiece placement position.

[0043] Specifically, when setting up, the driving mechanism is arranged opposite to the workpiece placement position, and the driver 2 can be realized by using a cylinder or a hydraulic rod. During loading, the driver 2 extends to push the pushing plate 3 forward, and the pushing plate 3 pushes the lowermost workpiece forward into the workpiece placement position. After the pushing plate 3 retracts, the workpiece 14 in the material receiving cylinder 4 falls due to its own gravity, and a new workpiece falls into the gap. The driving mechanism pushes the next workpiece forward, and so on to achieve automatic loading.

[0044] In order to better push the workpiece, as Figure 4 shown, an arc-shaped opening 31 is provided at the front end of the pushing plate 3. The setting of the arc-shaped opening 31 makes the pushing plate 3 more suitable for circular sheet workpieces. Of course, when processing square sheet workpieces, the arc-shaped opening 31 may not be provided.

[0045] A baffle 12 is provided on the platform 1. Specifically, the baffle 12 is located in front of the workpiece placement position. When the workpiece 14 is pushed to the workpiece placement position, its front end can abut against the baffle 12. In other words, the baffle 12 is used to limit the pushing position of the workpiece. When the drive mechanism extends forward to the set position, the workpiece is just pushed onto the workpiece placement position, and the front end of the workpiece just abuts against the baffle 12. The baffle 12 can prevent the workpiece from moving forward excessively due to inertia. The baffle 12 can effectively limit the pushing position of the workpiece 14, so that the workpiece 14 can be accurately pushed to the workpiece placement position. Figure 2 As shown.

[0046] In some other embodiments, the workpiece placement position can also be a cavity formed on the platform. The size and shape of the cavity match the workpiece. When the drive mechanism pushes the workpiece forward, the workpiece can fall into the cavity. Based on this structure, the baffle 12 may not be provided.

[0047] In addition, two limiting plates 9 are arranged parallel to each other on the upper surface of the platform 1, forming a pushing channel between the two limiting plates 9. When set up, the two limiting plates 9 are respectively located on both sides of the receiving cylinder 4, so that the pushing channel extends from below the receiving cylinder 4 to the workpiece placement position. The workpiece placement position is located within the pushing channel, and the width of the pushing channel matches the width of the workpiece, meaning that the falling workpiece can just land within the pushing channel. When the drive mechanism extends, the workpiece 14 is pushed along the pushing channel to the workpiece placement position.

[0048] In this embodiment, the pushing path of the workpiece 14 can be limited by the pushing channel, so as to ensure that the workpiece 14 can be accurately pushed to the workpiece placement position.

[0049] In this embodiment, the air jet 10 is located on the edge of the workpiece placement position near the receiving cylinder 4. A collection hopper 13 is provided on the platform 1, and the collection hopper 13 is positioned opposite the air jet 10. When the workpiece is pushed to the workpiece placement position, the edge of the workpiece covers the air jet 10. After punching is completed, the air pump is activated, and the gas instantly blown out by the air pump blows one side of the workpiece up, causing the workpiece to flip forward and fall into the collection hopper 13. Figure 3 As shown, this facilitates the collection of workpieces.

[0050] In this embodiment, the air jet 10 is located at the edge of the workpiece placement position. Therefore, when the air pump blows air, the workpiece will flip forward and fall for collection. If the air jet 10 is located near the middle of the workpiece placement position, when air is blown, the workpiece may be blown upwards and may fall back to its original position, making it impossible to unload.

[0051] In other embodiments, the lower end of the receiving cylinder 4 is connected to an adjusting cylinder 8, which can move up and down to adjust the width of the gap, thereby making this embodiment applicable to workpieces 14 of different thicknesses. Specifically, the adjusting cylinder 8 and the receiving cylinder 4 can be connected by a thread, and the height of the adjusting cylinder 8 can be easily adjusted by simply turning it.

[0052] In other embodiments, the top of the material receiving cylinder 4 is provided with a plurality of auxiliary support rods 5 spaced circumferentially, and the auxiliary support rods 5 are vertically arranged. In this embodiment, the number of auxiliary support rods 5 is set to three. The arrangement of the auxiliary support rods 5 can increase the storage capacity of the workpieces while reducing the weight of the device; at the same time, there is a gap between the two auxiliary support rods 5, which also facilitates the addition and placement of workpieces in the space enclosed by the three auxiliary support rods 5. As the number of workpieces in the material receiving cylinder 4 decreases, the workpieces between the three auxiliary support rods 5 enter the material receiving cylinder 4.

[0053] In addition, the wall of the receiving cylinder 4 is provided with an observation port 6, which extends along the axial direction of the receiving cylinder 4. The number of unprocessed workpieces inside the receiving cylinder 4 can be observed through the observation port 6, making it easy to determine whether workpieces need to be added to the receiving cylinder 4.

[0054] In this embodiment, the workpiece 14 is automatically unloaded by its own weight. The drive mechanism then pushes the fallen workpiece 14 to the workpiece placement position. After the workpiece is punched, it is blown by an air pump to unload. This method has high loading and unloading efficiency and lower equipment cost and maintenance cost compared to the loading and unloading method using a robotic arm.

[0055] It should be noted that all features disclosed in this specification, or all steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and / or steps.

[0056] Furthermore, the specific embodiments described above are exemplary. Those skilled in the art can devise various solutions inspired by the disclosure of this utility model, and these solutions all fall within the scope of this utility model and its protection. Those skilled in the art should understand that this utility model specification and its drawings are illustrative and not intended to limit the scope of the claims.
