DETAILED DESCRIPTION

[0037] Before any embodiments of the present application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the foregoing drawings.

[0038] In this application, the terms "comprises," "includes," "has," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0039] In this application, the term "and / or" is a description of the association relationship between related objects, indicating that three relationships can exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent three situations: the existence of a centrifugal vortex magnetic pump alone, the existence of a centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump at the same time, and the existence of a centrifugal vortex magnetic pump alone. In addition, the character " / " in this application generally indicates that the related objects are in an "and / or" relationship.

[0040] In this application, the terms "connect," "combine," "couple," and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without an intermediary, and an indirect connection refers to two parts or components being connected to at least one intermediary, with the two parts or components being connected via the intermediary. Furthermore, "connect" and "couple" are not limited to physical or mechanical connections or couplings and may include electrical connections or couplings.

[0041] In this application, it will be understood by those skilled in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerance caused by manufacturing, assembly, use, etc. associated with a specific value. Such terms should also be considered to disclose a range defined by the absolute values of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values that do not use relative terms should also be disclosed as specific values with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0042] In this application, it will be understood by those skilled in the art that the function performed by an assembly can be performed by one assembly, multiple assemblies, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one assembly, or a combination of multiple parts.

[0043] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to the other element "upper" or "lower", but also be indirectly connected to the other element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, below can include directly below, lower left, lower right, lower front and lower back, etc.

[0044] See also Figures 1 to 4 This embodiment provides a punching device, which includes a frame 1, a punching lower die 2, a lower driving mechanism 3, a punching upper die 4, an upper driving mechanism 5, a feeding mechanism, a blanking mechanism 6 and a conveying mechanism 8.

[0045] Specifically, the punching lower die 2 is horizontally slidably arranged on the frame 1. The punching lower die 2 is used to carry and position the product. The lower driving mechanism 3 is used to drive the punching lower die 2 to slide. The punching upper die 4 is vertically slidably arranged on the frame 1. The punching upper die 4 can press the product carried by the punching lower die 2 and punch the material head on the product. The upper driving mechanism 5 is used to drive the punching upper die 4 to slide. The feeding mechanism is configured to supply the product produced by the injection molding machine to the punching lower die 2. The unloading mechanism 6 is arranged on the frame 1. The unloading mechanism 6 is configured to supply an empty material tray 9 to collect the products that have been punched through the material tray 9. The conveying mechanism 8 is arranged on the frame 1. The conveying mechanism 8 is configured to convey the products that have been punched on the punching lower die 2 to the material tray 9 supplied by the unloading mechanism 6. It should be pointed out that, in the embodiment, the feeding mechanism is a robot in the previous process, which can directly transport the products produced by the injection molding machine in the previous process to the punching lower mold 2, and will not be described in detail.

[0046] In actual application, the lower driving mechanism 3 first drives the punching lower die 2 to slide until the punching lower die 2 is away from the punching upper die 4, and then the feeding mechanism supplies the product produced by the injection molding machine to the punching lower die 2, and then the lower driving mechanism 3 drives the punching lower die 2 to slide until the punching lower die 2 is located below the punching upper die 4, and then the upper driving mechanism 5 drives the punching upper die 4 to descend until the punching upper die 4 presses the product carried by the punching lower die 2 and punches the material head on the product, thus completing the punching of the material head, and then the upper driving mechanism 5 drives the punching upper die 4 to rise and reset, and then the lower driving mechanism 3 drives the punching lower die 2 to slide until the punching lower die 2 is away from the punching upper die 4, and finally the conveying mechanism 8 conveys the product that has been punched on the punching lower die 2 to the unloaded material tray 9 supplied by the unloading mechanism 6.

[0047] It is understandable that by cooperating with the punching die 4 and the punching die 2 to punch the material head on the product, the punching position is more accurate than the manual cutting method of the material head in the prior art, thereby improving the production quality. It is also understandable that the punching method by the feeding mechanism, the conveying mechanism 8, the upper drive mechanism 5 and the lower drive mechanism 3 and other components cooperate with each other, compared with the manual cutting method in the prior art, is more efficient, and the operator is not easily fatigued, the labor intensity is low, and in addition, it avoids the situation where the operator needs to contact the high-temperature product, thereby avoiding the situation where the operator is burned.

[0048] Generally speaking, traditional injection molding production lines all use an assembly line production method to produce injection molded products. That is, traditional injection molding production lines can produce large quantities of injection molded products in a short time and have high production efficiency. Therefore, in order to ensure that the punching efficiency of the punching equipment can match the production efficiency of the injection molding production line, in this embodiment, two punching lower dies 2 are provided. The two punching lower dies 2 are arranged along their sliding direction and connected as a whole, so that the lower drive mechanism 3 can simultaneously drive the two punching lower dies 2 to slide. This arrangement allows one punching lower die 2 and punching upper die 4 to cooperate in punching the product while the transport mechanism 8 can load and unload the other punching lower die 2.

[0049] To further improve the punching efficiency of the punching equipment, two upper punching dies 4 are provided. The two upper punching dies 4 are spaced apart along the sliding direction of the lower punching die 2. The number of upper drive mechanisms 5 is two corresponding to the number of upper punching dies 4. A loading and unloading station capable of accommodating one lower punching die 2 is formed between the two upper punching dies 4, so that when one lower punching die 2 is in the loading and unloading station, the other lower punching die 2 can cooperate with any upper punching die 4.

[0050] It is understandable that by placing the loading and unloading station between the two punching upper dies 4, it is possible to ensure that when the transport mechanism 8 performs loading and unloading operations on any punching lower die 2, there is always one punching upper die 4 in a coordinated working state with the other punching lower die 2. It should be noted that the upper drive mechanism 5 can be any linear drive mechanism in the prior art, such as a pneumatic cylinder, an electric cylinder, a linear module, etc. In this embodiment, the upper drive mechanism 5 is a pneumatic cylinder. It should also be noted that the lower drive mechanism 3 can be any linear drive mechanism capable of multi-stage drive in the prior art, such as an electric cylinder, a linear module, etc. In this embodiment, the lower drive mechanism 3 is a linear module.

[0051] In order to further improve the punching efficiency of the punching equipment, each punching lower die 2 can carry and position multiple products, and the punching upper die 4 corresponds to the structural setting of the punching lower die 2, so that multiple products can be punched at the same time. In this embodiment, the punching lower die 2 includes two structures for carrying and positioning products. It should be noted that the specific structure of the punching lower die 2 and the punching upper die 4 depends on the structure of the product, so this embodiment will not be described in detail. It should also be noted that the design method of the punching lower die 2 and the punching upper die 4 is well known to those skilled in the art and will not be described in detail.

[0052] The handling mechanism 8 includes a multi-axis manipulator 81 and a gripper 82. The gripper 82 is disposed at the movable end of the multi-axis manipulator 81 and is used to grasp products. In this embodiment, the gripper 82 includes two pneumatic gripper fingers, which can simultaneously grasp two small products or, in combination, grasp a large product, providing high applicability.

[0053] It is understandable that if unqualified products are not promptly processed, they will flow into the next process, thereby affecting the product yield rate. To this end, the punching equipment also includes a detection mechanism 101 disposed on the frame 1. The detection mechanism 101 is located above the loading and unloading station. The detection mechanism 101 is configured to detect whether the punching lower die 2 located at the loading and unloading station is loaded with products, and is also configured to detect whether the punched products are qualified. The multi-axis manipulator 81 is electrically connected to the detection mechanism 101. This configuration enables the multi-axis manipulator to promptly process unqualified products, thereby preventing unqualified products from flowing into the next process.

[0054] The transport mechanism 8 further comprises a throwing box 102 provided on the frame 1, and the throwing box 102 is used for storing unqualified products. Such a setting makes it easier for the multi-axis manipulator to handle unqualified products.

[0055] The unloading mechanism 6 comprises a storage frame 61, a drive assembly 62, and a pull assembly 63. The storage frame 61 includes a storage chamber capable of vertically stacking multiple trays 9. The drive assembly 62 is mounted on the frame 1 and is configured to lift the tray 9 at the bottom of the storage chamber. The pull assembly 63 is mounted on the frame 1 and is configured to pull the tray 9 at the top of the storage chamber out of the chamber. This arrangement enables automated feeding of fully loaded trays 9.

[0056] It should be noted that the drive assembly 62 can select any linear drive structure such as a cylinder, a linear module, etc. in the prior art. It should also be noted that the pulling assembly 63 includes a claw that can hook the material tray 9 and a drive structure that drives the claw to move in a preset direction. The drive structure can select any linear drive structure in the prior art. It should also be pointed out that the material tray 9 is correspondingly provided with a card slot that is compatible with the claw. In addition, the empty material trays 9 are manually arranged one by one in the storage cavity, and the fully loaded material trays 9 are also manually taken out one by one from the storage cavity. Of course, the storage frame 61 can also be directly replaced as a whole.

[0057] To achieve uninterrupted production, in this embodiment, two unloading mechanisms 6 are provided. This arrangement allows one unloading mechanism 6 to enter a neutral position when manually replacing a tray 9 or a storage frame 61, switching to the other unloading mechanism 6 to continue unloading. If one tray 9 in one unloading mechanism 6 becomes fully loaded and needs to be replaced, the other unloading mechanism 6 can also enter a neutral position to continue unloading, thus achieving uninterrupted production. Furthermore, uninterrupted production ensures that the injection molding machine does not need to be stopped for waiting, thus avoiding the problem of plastic hardening in the material pipe due to machine downtime, requiring pipe cleaning and resetting.

[0058] It should be noted that if the shavings dropped from the product are not collected in time, they will accumulate and clog the punching die 2, affecting the production environment. Therefore, the punching equipment also includes a waste box 103 provided on the frame 1. The waste box 103 is located below the punching die 2 and is used to store the shavings dropped from the product.

[0059] In order to improve the convenience of collecting the material heads, the punching lower die 2 includes a waste channel 21 for discharging the fallen material heads. The waste channel 21 is connected to the waste box 103 through the guide channel, so that the fallen material heads can directly fall into the waste box 103 through the waste channel 21 and the guide channel.

[0060] This embodiment further provides an injection molding production line, which includes an injection molding machine, a transport device, and the aforementioned punching and shearing device, wherein the transport device is used to transport products produced by the injection molding machine to the punching and shearing device. It is understood that the injection molding production line including the aforementioned punching and shearing device can improve production quality and production efficiency.

[0061] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
