The accompanying drawings have illustrated specific embodiments of this application, which will be described in more detail below. These drawings and textual descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0032] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0033] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. Furthermore, components, features, and elements with the same names in different embodiments of this application may have the same meaning or different meanings, the specific meaning of which must be determined by its interpretation in that specific embodiment or further in conjunction with the context of that specific embodiment.

[0034] It should be understood that although the terms first, second, third, etc., may be used herein to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this document, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if," as used herein, can be interpreted as "when," "when," or "in response to determination." Furthermore, as used herein, the singular forms "a," "an," and "the" are intended to also include the plural forms unless the context indicates otherwise. It should be further understood that the terms "comprising," "including," indicate the presence of the stated feature, step, operation, element, component, item, kind, and / or group, but do not exclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, components, items, kinds, and / or groups. The terms "or" and "and / or" as used herein are to be interpreted as inclusive, or mean any one or any combination thereof. Therefore, "A, B, or C" or "A, B, and / or C" means "any one of the following: A; B; C; A and B; A and C; B and C; A, B, and C." Exceptions to this definition only occur when combinations of elements, functions, steps, or operations are inherently mutually exclusive in some way. When describing the structure of a component, when referring to a layer or region as being "above" or "on top of" another layer or region, it can mean being directly above another layer or region, or containing other layers or regions between it and another layer or region. Furthermore, if the component is flipped, the layer or region will be located "below" or "under" another layer or region. In embodiments of this application, "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0035] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0036] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no specific meaning in itself. Therefore, "module," "part," or "unit" may be used interchangeably.

[0037] The applicant discovered that the packaging box may include a box body and a box lid, with a buckle on the side wall of one of the box body and the snap-fit ​​hole on the side wall of the other, so that the packaging box can be closed by fastening the box lid to the opening of the box body and engaging the buckle with the snap-fit ​​hole.

[0038] Currently, the production and processing of materials such as boxes or lids with snap-fit ​​holes requires two processes: forming and punching. After the material is formed, it is transferred to a punching device for punching. After punching, the material is transferred to the downstream production line for subsequent processes.

[0039] However, in existing punching equipment, material transfer is mainly done manually, which results in low material production efficiency and high labor and material costs in the production process.

[0040] In view of the above problems, the applicant proposes a punching device, including a carrying mechanism, a punching mechanism, a feeding mechanism, and a discharging mechanism. The carrying mechanism is provided with a punching position. The punching mechanism is mounted on the carrying mechanism and includes a punching cutter located on one side of the punching position. The punching cutter is movable in the direction of approaching or moving away from the punching position, so that the punching cutter can punch holes in the material at the punching position. The feeding mechanism is mounted on the carrying mechanism and is used to transport the material to the punching position. The discharging mechanism is mounted on the carrying mechanism and is used to remove the material from the carrying mechanism, thereby realizing automatic feeding and automatic discharging to improve production efficiency and reduce the labor and material costs of material production.

[0041] First Embodiment

[0042] Please see Figure 1 and Figure 2In a first aspect, embodiments of this application provide a punching device, including a carrying mechanism 10, a punching mechanism 20, a feeding mechanism, and a discharging mechanism 30. The carrying mechanism 10 is provided with a punching position 11. The punching mechanism 20 is disposed on the carrying mechanism 10 and includes a punching cutter 21 disposed on one side of the punching position 11. The punching cutter 21 is movable in a direction toward or away from the punching position 11. The feeding mechanism is disposed on the carrying mechanism 10 and is used to transport material 40 to the punching position 11. The discharging mechanism 30 is disposed on the carrying mechanism 10 and is used to remove material 40 from the punching position 11.

[0043] It should be clarified that the punching device of this application can be applied to the packaging field to punch holes in packaging boxes such as lock boxes. Alternatively, the punching device of this application can also be applied to other fields to punch holes in other materials 40 that require punching. For example, the punching device of this application can also be used to punch holes in materials 40 such as wood boards and leather. The actual application of the punching device of this application is not limited in this embodiment.

[0044] The supporting mechanism 10 can be used to support at least one of the material 40, the punching mechanism 20, the feeding mechanism, and the unloading mechanism 30. The supporting mechanism 10 may include a first supporting platform 12, and the punching position 11 is disposed on the supporting surface of the first supporting platform 12. In the punching mechanism 20, the punching cutter 21 can extend in a direction close to or away from the punching position 11. That is, the direction in which the punching cutter 21 approaches or moves away from the punching position 11 is the length direction of the punching cutter 21. The punching mechanism 20 may also include a first driving member 22, which is connected to the punching cutter 21 to drive the punching cutter 21 to move in a direction close to or away from the punching position 11, so that the punching cutter 21 can punch the material 40 in the punching position 11. Optionally, the first driving member 22 may include, but is not limited to, a cylinder, a hydraulic cylinder, a motor, or other driving structures. Alternatively, the first driving member 22 may also be a combination of a cylinder, a hydraulic cylinder, a motor, or other driving structures and a connecting rod or other transmission structure. This embodiment is not limited to this. The feeding and / or unloading mechanism 30 includes, but is not limited to, structures such as robotic arms and suction cups capable of gripping materials 40. The shape and size of the punching position 11 can be adapted to the shape and size of the material 40. For example, when the material 40 is square, the shape of the punching position 11 can be square; when the material 40 is round, the shape of the punching position 11 can be round; and when the material 40 is irregular in shape, the shape of the punching position 11 is also irregular in shape.

[0045] This application provides a punching device, including a carrying mechanism 10, a punching mechanism 20, a feeding mechanism, and a discharging mechanism 30. The carrying mechanism 10 is provided with a punching position 11. The punching mechanism 20 is mounted on the carrying mechanism 10 and includes a punching cutter 21 mounted on one side of the punching position 11. The punching cutter 21 is movable in the direction of approaching or moving away from the punching position 11, so that the punching cutter 21 can punch holes in the material 40 on the punching position 11. The feeding mechanism is mounted on the carrying mechanism 10 and is used to transport the material 40 to the punching position 11. The discharging mechanism 30 is mounted on the carrying mechanism 10 and is used to remove the material 40 from the carrying mechanism 10, thereby realizing automatic feeding and automatic discharging, eliminating the need for manual transfer of the material 40, enabling the punching device to automatically connect and punch holes, thereby improving production efficiency and reducing the labor and material costs of producing the material 40.

[0046] It is understood that in the punching structure, the number of punching cutters 21 can be one or more. The number and position of punching cutters 21 can be flexibly set according to the number and position of snap-fit ​​holes to be formed on the material 40. This embodiment does not limit this.

[0047] According to a first aspect of the embodiments of this application, the number of punching positions 11 on the carrying mechanism 10 can be multiple, and the multiple punching positions 11 are arranged at intervals. Correspondingly, the number of punching mechanisms 20 can be multiple, and the multiple punching mechanisms 20 are arranged one-to-one with the multiple punching positions 11. Furthermore, the feeding mechanism is used to transport multiple materials 40 one-to-one to the multiple punching positions 11, and the unloading mechanism 30 is used to remove multiple materials 40 from the carrying mechanism 10, thereby enabling the simultaneous transfer of multiple materials 40, so that the punching device can punch multiple materials 40 at the same time, thereby improving the punching efficiency.

[0048] Furthermore, the supporting mechanism 10 may also have a second supporting platform 13, and the number of first supporting platforms 12 may be multiple. Multiple first supporting platforms 12 are sequentially arranged on the second supporting platform 13, and multiple punching positions 11 and multiple punching mechanisms 20 are arranged one-to-one on multiple first supporting platforms 12. Thus, by individually arranging multiple punching positions 11 and multiple punching mechanisms 20 one-to-one, interference between adjacent punching mechanisms 20 can be reduced.

[0049] Please see Figure 2 According to a first aspect of the present application, the punching device further includes a limiting mechanism 50 disposed on the bearing mechanism 10. The limiting mechanism 50 includes a plurality of limiting blocks 51 disposed in the punching position 11. The plurality of limiting blocks 51 are spaced apart along the edge of the punching position 11. The side of the limiting block 51 facing the edge of the punching position 11 is a bonding surface 52, which is used to bond with the inner wall of the material 40.

[0050] It is understandable that when the material 40 is placed in the punching position 11, the material 40 can be equivalent to covering the punching position 11. The side of the material 40 with the opening is in contact with the bearing surface of the bearing mechanism 10, while the bottom wall of the material 40 is separated from the bearing surface. Therefore, when multiple limiting blocks 51 are provided in the punching position 11, the multiple limiting blocks 51 are located in the space formed by the bearing surface and the material 40. Furthermore, since the multiple limiting blocks 51 are spaced along the edge of the punching position 11, the side of the limiting block 51 facing the edge of the punching position 11 is the contact surface 52. Therefore, the contact surface 52 of the limiting block 51 can be in contact with the inner wall of the material 40. It should be clarified that the edge of the punched position 11 in this embodiment refers to the outline of the punched position 11, that is, the boundary line between the punched position and other areas on the bearing mechanism 10. When the punched position 11 is square, the shape formed by its edge is square. When the punched position 11 is circular, the shape formed by its edge is circular. When the punched position 11 is other irregular shapes, the shape formed by its edge is the irregular shape corresponding to the punched position 11.

[0051] The number of limiting blocks 51 can be reasonably set according to the type of material 40. For example, when the material 40 is a square packaging box, the punching position 11 can also be square. In this case, the number of limiting blocks 51 can be four, and the four limiting blocks 51 are arranged alternately. Each limiting block 51 can be located at the junction of two adjacent edges of the punching position 11. At this time, the contact surface 52 of each limiting block 51 can include two sub-surfaces. The two sub-surfaces are adjacent to each other and face the two adjacent edges of the punching position 11 respectively. The two sub-surfaces are respectively in contact with the inner wall of the material 40. Therefore, each limiting block 51 can limit the material 40 in two directions.

[0052] In this embodiment, by setting multiple limiting blocks 51 in the punching position 11, the multiple limiting blocks 51 are arranged sequentially at intervals along the circumference of the punching position 11 and close to the edge of the punching position 11. The side of the limiting block 51 facing the edge of the punching position 11 forms a contact surface 52, which is in contact with the inner wall of the material 40. Therefore, when the material 40 is placed in the punching position 11, the multiple limiting blocks 51 can be located inside the material 40 and abut against the inner wall of the material 40 along the circumference of the punching position 11, thereby limiting the material 40 in a direction parallel to the punching position 11 to prevent the material 40 from shifting position, improving the positional accuracy of the material 40 placed on the punching position 11, thereby reducing the risk of positional deviation and excessive burrs in the snap-fit ​​hole formed by the punching of the material 40.

[0053] Optionally, the shape of the bonding surface 52 can be adapted to the shape of the inner wall of the material 40 to ensure a good bonding effect. For example, when the inner wall of the material 40 forms a concave portion, the bonding surface 52 can form a convex portion corresponding to the concave portion, and when the inner wall of the material 40 forms a convex portion, the bonding surface 52 can form a concave portion corresponding to the convex portion, thereby ensuring that the bonding surface 52 is completely bonded to the inner wall of the material 40.

[0054] Please see Figure 3 and Figure 4 According to a first aspect of the embodiments of this application, the punching mechanism 20 further includes a punching auxiliary component 23. The punching auxiliary component 23 includes an abutment portion 231 disposed in the punching position 11. The abutment portion 231 has a first through hole 232 corresponding to the punching knife 21 along the moving direction of the punching knife 21. An abutment surface 233 is formed on the side of the abutment portion 231 facing the punching knife 21. The abutment surface 233 is used to abut against the inner wall of the material 40. The first through hole 232 is used for the punching knife 21 to be inserted.

[0055] It is understandable that the direction of movement of the punching cutter 21 is the direction in which the punching cutter 21 moves closer to or further away from the punching position 11, which is the length direction of the punching cutter 21. The punching auxiliary component 23 is mounted on the supporting mechanism 10 and can be connected to the supporting mechanism 10 by fasteners such as bolts.

[0056] In the punching auxiliary component 23, the abutting part 231 is located inside the punching position 11, and the abutting part 231 has an abutting surface 233 formed on the side facing the punching cutter 21. That is, the abutting surface 233 is located on the side of the abutting part 231 facing the edge of the punching position 11. When the material 40 is placed on the punching position 11, the inner wall of the material 40 can fit against the abutting surface 233. The abutment portion 231 has a first through hole 232 formed along the moving direction of the punching cutter 21. The first through hole 232 is correspondingly provided with the punching cutter 21. Therefore, when the punching cutter 21 moves toward the punching position 11, the punching cutter 21 can first pass through the side wall of the material 40 and insert into the first through hole 232, thereby punching a snap-fit ​​hole on the side wall of the material 40. During this process, the abutment portion 231 abuts against the inside of the material 40, which can prevent other parts of the material 40 except the snap-fit ​​hole from being deformed under the punching of the punching cutter 21.

[0057] Please continue reading. Figure 3 and Figure 4 According to a first aspect of the present application, the punching auxiliary member 23 further includes a guide portion 234. The guide portion 234 is spaced apart from the abutment portion 231 along the moving direction of the punching cutter 21 and is located on the side of the abutment portion 231 facing the punching cutter 21. The guide portion 234 forms a second through hole 235 corresponding to the punching cutter 21 along the moving direction of the punching cutter 21. The second through hole 235 is used to guide the punching cutter 21 during its movement.

[0058] The guide portion 234 has a second through hole 235 corresponding to the punching cutter 21 along the moving direction of the punching cutter 21. The guide portion 234 is spaced apart from the abutment portion 231 along the moving direction of the punching cutter 21 and is located on the side of the abutment portion 231 facing the punching cutter 21. Therefore, during the process of the punching cutter 21 moving towards the punching position 11 to pass through the side wall of the material 40 and insert into the first through hole 232 of the abutment portion 231, the punching cutter 21 can pass through the second through hole 235 of the guide portion 234. Thus, the guide portion 234 can guide the punching cutter 21 during its movement, improve the stability of the punching cutter 21, and prevent the punching cutter 21 from deviating and affecting the punching position 11 accuracy of the material 40.

[0059] It is understandable that when the punching cutter 21 is reset in a direction away from the punching position 11, the punching cutter 21 can be located on the side of the guide portion 234 away from the abutment portion 231, or the punching cutter 21 can also stay in the second through hole 235 of the guide portion 234. Thus, the guide portion 234 can also limit the punching cutter 21 when it stops moving, so as to further prevent the punching cutter 21 from shifting position.

[0060] Please continue reading. Figure 3 and Figure 4 According to a first aspect of the embodiments of this application, the punching mechanism 20 further includes a first driving member 22. The first driving member 22 includes a cylinder body 221 and a piston rod 222 connected to the cylinder body 221. The piston rod 222 extends along the moving direction of the punching cutter 21 and is connected to the punching cutter 21, thereby driving the punching cutter 21 to move. The structure is simple and has high stability.

[0061] It is understandable that the cylinder body 221 can be located on the side of the punching cutter 21 away from the punching position 11. In this case, after the piston rod 222 extends, it can drive the punching cutter 21 to move towards the punching position 11. Alternatively, the cylinder body 221 can also be located below the punching position 11 or on the side of the punching position 11 away from the punching cutter 21. In this case, after the piston rod 222 retracts, it can drive the punching cutter 21 to move towards the punching position 11.

[0062] Please continue reading. Figure 3 and Figure 4 According to a first aspect of the embodiments of this application, the punching mechanism 20 further includes a support member 24, which is disposed on the side of the cylinder body 221 facing the punching cutter 21. The support member 24 is connected to the cylinder body 221 and the bearing mechanism 10 respectively, and the piston rod 222 passes through the support member 24 and extends to be connected to the punching cutter 21.

[0063] The support member 24 has a through hole along the extension direction of the piston rod 222. The piston rod 222 can pass through the through hole and extend to connect with the punch 21. Therefore, the support member 24 can guide the piston rod 222 during its extension and retraction, preventing the piston rod 222 from vibrating or shifting position, which would affect the stability of the punch 21. Furthermore, the support member 24 is connected to both the cylinder body 221 and the bearing mechanism 10, which can also improve the stability of the cylinder body 221 and further improve the stability of the punch 21.

[0064] Please continue reading. Figure 3 According to a first aspect of the embodiments of this application, the punching mechanism 20 further includes a mounting member 25, which is connected to the punching cutter 21 and the piston rod 222 respectively. The piston rod 222 is connected to the punching cutter 21 through the mounting member 25, thereby facilitating the installation and disassembly of the punching cutter 21.

[0065] Please see Figure 5 According to a first aspect of the embodiments of this application, the mounting member 25 includes a mounting portion 251 and a limiting pin 252. The punching cutter 21 is inserted into the mounting portion 251, and the limiting pin 252 passes through the punching cutter 21 and is inserted into the mounting portion 251. The extending direction of the limiting pin 252 is perpendicular to the moving direction of the punching cutter 21.

[0066] In this embodiment, the punching cutter 21 is inserted into the mounting portion 251. Therefore, the mounting portion 251 can limit the punching cutter 21 along the width and thickness directions, preventing the punching cutter 21 from shifting position along the width and thickness directions and affecting the punching accuracy of the material 40. The limiting pin 252 passes through the punching cutter 21 and is inserted into the mounting portion 251. The extension direction of the limiting pin 252 is perpendicular to the moving direction of the punching cutter 21. Thus, the limiting pin 252 can limit the punching cutter 21 along the moving direction, preventing the punching cutter 21 from separating from the mounting part 25 during movement. The structure is simple, the assembly is convenient, and the limiting effect is good.

[0067] Please continue reading. Figure 5 According to a first aspect of the embodiments of this application, the mounting part 251 includes a first wall plate 253, a second wall plate 254 and a third wall plate 255 spaced apart along the moving direction of the punching cutter 21. The second wall plate 254 includes a main body 256 and a fixing part 257 connected to the side of the main body 256 near the first wall plate 253. The punching cutter 21 passes through the first wall plate 253 and abuts against the side of the main body 256 near the first wall plate 253. The limiting pin 252 passes through the punching cutter 21 and is inserted into the fixing part 257. Therefore, cavities can be formed between the first wall plate 253 and the second wall plate 254 and between the second wall plate 254 and the third wall plate 255, thereby reducing the weight of the mounting part 251.

[0068] The mounting part 251 may also include a side panel that is arranged circumferentially around the first wall panel 253. The side panel is connected to the first wall panel 253, the second wall panel 254 and the third wall panel 255 respectively, so as to enclose the first wall panel 253, the second wall panel 254 and the third wall panel 255 to form two cavities.

[0069] Optionally, the first wall panel 253, the second wall panel 254 and the third wall panel 255 can also be locked along the extension direction of the punching tool 21 by fasteners such as bolts to improve structural strength.

[0070] It is understood that the mounting part 251 and the piston rod 222 can be connected by fasteners such as bolts, or by welding, bonding or other methods. This embodiment does not limit the connection.

[0071] For example, the mounting component 25 may also include a fastening bolt, and the piston rod 222 can be locked onto the mounting portion 251 by the fastening bolt. When the cylinder body 221 is positioned on the side of the punching cutter 21 away from the punching position 11, the piston rod 222 can pass through the third wall plate 255 and abut against the main body portion 256 of the second wall plate 254. At this time, the fastening bolt can pass through the main body portion 256 of the first wall plate 253 and the second wall plate 254 in sequence from the side of the first wall plate 253 away from the second wall plate 254, and be inserted into the piston rod 222 to fix the piston rod 222. When the cylinder body 221 is positioned below the punching position 11 or on the side of the punching position 11 away from the punching cutter 21, the piston rod 222 can pass through the first wall plate 253 and abut against the main body 256. At this time, the fastening bolt can pass through the third wall plate 255 and the main body 256 in sequence from the side of the third wall plate 255 away from the second wall plate 254, and be inserted into the piston rod 222 to fix the piston rod 222.

[0072] Furthermore, the fastening bolt and piston rod 222 can be connected by threads to ensure the connection strength between the two.

[0073] According to a first aspect of the embodiments of this application, the punching mechanism 20 may further include at least one guide post, the extension direction of which is parallel to the extension direction of the piston rod 222. The guide post passes through the support member 24 from the side of the support member 24 near the cylinder body 221 and is connected to the mounting member 25. The guide post is configured to be telescopically oriented along the extension direction of the piston rod 222, so that it can extend or retract synchronously during the movement of the piston rod 222 driving the punching cutter 21, thereby further guiding the piston rod 222 and the punching cutter 21 and improving the stability of the piston rod 222 and the punching cutter 21.

[0074] Please continue reading. Figure 2According to a first aspect of the embodiments of this application, the support mechanism 10 includes a support plate 14, the support plate 14 includes a first side P1 and a second side P2 disposed opposite to each other along a first direction X, a punching position 11 and a punching knife 21 are both located on the first side P1, and the punching knife 21 is disposed inclined towards the first side P1 from the end near the punching position 11 toward the direction away from the punching position 11, the first direction X is the thickness direction of the support plate 14.

[0075] In the support mechanism 10, the first support platform 12 may include a support plate 14 and multiple support rods. The multiple support rods are disposed on the second side P2 of the support plate 14 to support the support plate 14. The support plate 14 includes a first side P1 and a second side P2 disposed opposite to each other along a first direction X, where the first direction X is the thickness direction of the support plate 14. Therefore, the support surface of the first support platform 12 is located on the surface of the first side P1 of the support plate 14. The punching position 11 and the punching cutter 21 are both located on the first side P1 of the support plate 14. Therefore, when the material 40 is placed in the punching position 11, the material 40 is located on the first side P1 of the support plate 14, thereby enabling the punching cutter 21 to punch holes in the material 40.

[0076] It is understandable that, for materials such as packaging boxes, in order to increase the volume, the angle between the side wall and the bottom wall of the material 40 is usually greater than 90°. Therefore, when the material 40 is covered by the punching position 11, the side wall of the material 40 tilts from the side close to the bearing surface to the side away from the bearing surface towards the edge away from the punching position 11.

[0077] Therefore, in this embodiment, the punching cutter 21 is set to be inclined towards the first side P1 from the end near the punching position 11 to the direction away from the punching position 11, so that the moving direction of the punching cutter 21 can be perpendicular to the side wall of the material 40. In other words, the punching cutter 21 can punch the side wall of the material 40 perpendicularly, thereby ensuring the punching effect of the punching cutter 21.

[0078] It is understandable that other components such as the first drive member 22 in the punching mechanism 20 can also be tilted from the side close to the bearing surface to the side away from the edge of the punching position 11, so as to facilitate the movement of the punching cutter 21.

[0079] Please continue reading. Figure 2 According to a first aspect of the embodiments of this application, the support mechanism 10 includes a support plate 14, the support plate 14 includes a first side P1 and a second side P2 disposed opposite to each other along a first direction X, the punching position 11 and the punching knife 21 are both located on the first side P1, the punching mechanism 20 also includes a first driving member 22 located on the side of the punching knife 21 near the punching position 11, part of the first driving member 22 is located on the first side P1 and connected to the punching knife 21, and the remaining part of the first driving member 22 is located on the second side P2, the first direction X is the thickness direction of the support plate 14.

[0080] In this embodiment, the first driving member 22 is located on the side of the punching cutter 21 near the punching position 11, and part of the first driving member 22 is located on the first side P1 of the support plate 14 and connected to the punching cutter 21. The remaining part of the first driving member 22 is located on the second side P2 of the support plate 14. Compared with the first driving member 22 being located on the side of the punching cutter 21 away from the punching position 11, the assembly between the punching mechanism 20 and the support mechanism 10 can be more compact, reducing the overall volume of the two. At the same time, it can also avoid interference between the first driving member 22 and other structures in the punching device.

[0081] Please see Figure 6 According to a first aspect of the embodiments of this application, the supporting mechanism 10 includes a supporting plate 14, the supporting plate 14 includes a first side P1 and a second side P2 disposed opposite to each other along a first direction X, the punching position 11 and the punching cutter 21 are both located on the first side P1, the punching mechanism 20 also includes a guide member 26 disposed on the first side P1 and located in the punching position 11, the guide member 26 forms a guide cavity 261 and an inlet 262 and an outlet 263 communicating with the guide cavity 261, the inlet 262 is located on the side of the guide member 26 close to the punching cutter 21 and is disposed corresponding to the punching cutter 21, the guide member 26 passes through the supporting plate 14 and makes the outlet 263 communicate with the second side P2, the first direction X is the thickness direction of the supporting plate 14.

[0082] In this embodiment, a guide member 26 is provided on the first side P1 of the support plate 14, so that the guide member 26 is located at the punching position 11. In the guide member 26, the inlet 262 is located on the side of the guide member 26 close to the punching knife 21 and is correspondingly provided with the punching knife 21. Therefore, when the punching knife 21 passes through the side wall of the material 40 and punches a snap-fit ​​hole on the side wall, the waste material punched out can fall from the inlet 262 of the guide member 26 into the guide cavity 261, move to the outlet 263 in the guide cavity 261, and move out of the guide cavity 261 from the outlet 263, thereby guiding the waste material to the second side P2 of the support plate 14, so as to avoid the waste material accumulating in the punching position 11 and to prevent the waste material from being transported to the downstream production line along with the material 40 after the material 40 is punched.

[0083] Optionally, an opening may be formed on the support plate 14 along the first direction X, the opening connecting the first side P1 and the second side P2 of the support plate 14, and at least part of the guide member 26 may be located in the opening, thereby facilitating the flow of waste material in the guide cavity 261 from the discharge port 263 to the second side P2.

[0084] Optionally, the guide member 26 is inclined toward the second side P2 from the inlet 262 toward the outlet 263, so that the waste material in the guide cavity 261 can flow from the outlet 263 to the second side P2.

[0085] According to a first aspect of the embodiments of this application, the feeding mechanism includes a first gripper, a second driving member, a third driving member, and a fourth driving member. The second driving member is connected to the first gripper and is used to drive the first gripper to rotate around an axis extending in the second direction Y. The third driving member is connected to the second driving member. The fourth driving member is connected to the third driving member. A portion of the third driving member moves along either the first direction X or the second direction Y, and a portion of the fourth driving member moves along the other direction. The first direction X is perpendicular to the second direction Y.

[0086] The first direction X is the thickness direction of the support plate 14, and the second direction Y can be either the length direction or the width direction of the support plate 14. The second driving component can be a drive motor or other rotary drive structures such as a rotary cylinder. The third and fourth driving components can be linear drive structures such as cylinders or hydraulic cylinders, or combinations of rotary drive structures such as motors with other transmission structures; this embodiment does not impose any limitations.

[0087] In this embodiment, the first gripper is used to pick up and put down material 40. The second drive member is connected to the first gripper and is used to drive the first gripper to rotate around the axis extending in the second direction Y. Therefore, the first gripper can grip material 40 from multiple directions to improve its applicability. Furthermore, the third drive member is connected to the second drive member, and the fourth drive member is connected to the third drive member. Part of the third drive member moves along either the first direction X or the second direction Y, and part of the fourth drive member moves along the other direction. Thus, the third drive member can drive the second drive member and the first gripper connected to the second drive member to move along either the first direction X or the second direction Y. The fourth drive member can drive the third drive member, the second drive member, and the first gripper to move along the other direction, so as to move the material 40 gripped by the first gripper to the punch position 11 of the bearing mechanism 10. The structure is simple and the operation is convenient.

[0088] According to a first aspect of the embodiments of this application, the third driving member includes a first driving component and a first transmission component. The first driving component includes a first driving wheel, a first driven wheel, and a first conveyor belt respectively sleeved on the first driving wheel and the first driven wheel. The first driving wheel and the first driven wheel are spaced apart along a first direction X. The first transmission component is connected to the first conveyor belt and the first gripper respectively. Therefore, when the first driving wheel rotates, it can drive the first conveyor belt to move along the first direction X, thereby driving the first transmission component and the first gripper connected to the first transmission component to move along the first direction X through the first conveyor belt. The structure is simple and the transmission is stable.

[0089] And / or, the fourth driving component includes a second driving component and a second transmission component. The second driving component includes a second driving wheel, a second driven wheel, and a second conveyor belt respectively sleeved on the second driving wheel and the second driven wheel. The second driving wheel and the second driven wheel are spaced apart along the second direction Y. The second transmission component is connected to the second conveyor belt and the third driving component respectively. Therefore, when the second driving wheel rotates, it can drive the second conveyor belt to move along the second direction Y, thereby driving the second transmission component and the third driving component connected to the second transmission component to move along the second direction Y through the second conveyor belt. The structure is simple and the transmission is stable.

[0090] It should be clarified that, in this embodiment, the axial direction of the first driving wheel and the first driven wheel of the third driving member extends along the second direction Y or the third direction Z, and the axial direction of the second driving wheel and the second driven wheel of the fourth driving member extends along the third direction Z.

[0091] Optionally, the third and fourth driving components also include motors, with the motor shaft of the third driving component coaxially connected to the first driving wheel to drive the first driving wheel to rotate, and the motor shaft of the fourth driving component coaxially connected to the second driving wheel to drive the second driving wheel to rotate.

[0092] Please see Figure 7 According to a first aspect of the embodiments of this application, the unloading mechanism 30 is located on one side of the bearing mechanism 10 along the first direction X. The unloading mechanism 30 includes a second gripper 31, a fifth driving member 32 and a sixth driving member 33. The fifth driving member 32 is connected to the second gripper 31 and is used to drive the second gripper 31 to move along the first direction X. The sixth driving member 33 includes a third driving component and a third transmission component 331. The third driving component includes a third driving wheel 332, a third driven wheel 333 and a third conveyor belt 334 respectively sleeved on the third driving wheel 332 and the third driven wheel 333. The third driving wheel 332 and the third driven wheel 333 are spaced apart along the third direction Z. The third transmission component 331 is connected to the fifth driving member 32 and the third conveyor belt 334 respectively. The first direction X and the third direction Z are perpendicular to each other.

[0093] When the second direction Y is either the length direction or the width direction of the bearing plate 14, the third direction Z can be the other.

[0094] In this embodiment, the second gripper 31 is used to pick up and put down material 40. The fifth drive member 32 is connected to the second gripper 31 and is used to drive the second gripper 31 to move along the first direction X, thereby facilitating the second gripper 31 to pick up the material 40 placed in the punching position 11. In the sixth drive member 33, the third drive component includes a third driving wheel 332, a third driven wheel 333, and a third conveyor belt 334 respectively sleeved on the third driving wheel 332 and the third driven wheel 333. The third driving wheel 332 and the third driven wheel 333 move along the first direction X. The third direction Z is set at intervals. The third transmission component 331 is connected to the fifth drive component 32 and the third conveyor belt 334 respectively. Therefore, when the third drive wheel 332 rotates, it can drive the third conveyor belt 334 to move along the third direction Z. The third conveyor belt 334 drives the fifth drive component 32 and the second gripper 31 connected to the fifth drive component 32 to move along the third direction Z through the third transmission component 331, so that the material 40 gripped by the second gripper 31 can be placed on the downstream assembly line. The structure is simple and the transmission is stable.

[0095] It is understandable that during the punching process of material 40, the fifth driving member 32 and the sixth driving member 33 drive the second gripping member 31 to move along the first direction X toward the punching position 11 until it comes into contact with material 40, thereby limiting the material 40 along the first direction X.

[0096] Optionally, the unloading mechanism 30 may also include a guide member, which includes a slide rail and a slider slidably disposed on the slide rail. The slide rail extends along the third direction Z, and the slider is connected to the sixth driving member 33. Thus, the cooperation between the slide rail and the slider can guide the sixth driving member 33, thereby improving the stability of the sixth driving member 33 in moving the fifth driving member 32 and the second gripper 31 along the third direction Z.

[0097] Furthermore, there can be two guide members, which are spaced apart on both sides of the bearing mechanism 10 along the second direction Y. The slide rails of both guide members are connected to the sixth drive member 33 to improve the guiding effect.

[0098] Optionally, the fifth driving component 32 can be a linear drive structure such as a cylinder or hydraulic cylinder, and the third driving component can also include a drive motor. The motor shaft of the drive motor is coaxially connected to the third driving wheel 332 to drive the third driving wheel 332 to rotate.

[0099] Optionally, the first gripper and / or the second gripper 31 may include suction cups to pick up the material 40, thereby avoiding damage to the material 40. The number of suction cups may be one or more, and this embodiment does not limit the number.

[0100] It is understandable that when the bearing mechanism 10 is provided with multiple punch positions 11, the number of suction cups in the first gripper and / or the second gripper 31 can be multiple, and the multiple suction cups correspond one-to-one with the multiple punch positions 11 to pick up the material 40 in the corresponding punch position 11.

[0101] Optionally, the first gripper and / or the second gripper 31 may further include a support frame connected to the suction cup to support it. It is understood that the support frame in the first gripper is connected to the second drive member, and the support frame in the second gripper 31 is connected to the fifth drive member 32.

[0102] The above are merely preferred embodiments of this application and do not limit the patent scope of this application.
