Description

Technical Field

[0001] The present application relates to the technical field of battery processing equipment, and in particular to a pushing mechanism and a punching device with an overload protection function. Background Art

[0002] During the battery jig manufacturing process, a stamping device is required. In related technologies, the stamping device usually includes a stamping mechanism and a pushing mechanism. The stamping mechanism is used to complete the stamping of the battery jig, and the pushing mechanism is used to push the stamped battery jig out of the stamping mechanism.

[0003] Since the power source of the stamping mechanism and the power source of the pushing mechanism are the same power source, when the battery jig gets stuck on the stamping mechanism, the pushing mechanism is easily overloaded due to the jamming of the battery jig, thereby causing damage to the power source and affecting the normal operation of the stamping device.

[0004] Therefore, there is an urgent need for a pushing mechanism with an overload protection function to solve the above problems. Utility Model Content

[0005] The purpose of this application is to solve or at least alleviate some or all of the above problems. To this end, the purpose of this application is to provide a pusher mechanism and a punching device with an overload protection function, which can prevent the pusher mechanism from being overloaded due to the jamming of the battery fixture and avoid damage to the power source.

[0006] In order to achieve the above objectives, this application adopts the following technical solutions:

[0007] In a first aspect, a pushing mechanism with an overload protection function is provided, comprising:

[0008] carrier;

[0009] A drive assembly comprising a slider for transmission connection with a power source of the punching device, the slider being capable of reciprocating in a first direction relative to the carrier and having a pushing position and an avoidance position;

[0010] The pushing assembly includes a baffle, a pushing member and a guide transmission member. The baffle is fixedly connected to the slider. The pushing member has a through hole extending along a first direction. One end of the guide transmission member is fixedly connected to the baffle, and the other end is passed through the through hole. The friction force between the guide transmission member and the hole wall of the through hole is less than the maximum load force of the power source.

[0011] As an optional solution for the pushing mechanism with overload protection function, the pushing assembly also includes a damping adjustment part, and the pushing part also has a threaded hole connected to the through hole. The damping adjustment part is threadedly connected to the threaded hole, and the end face of the damping adjustment part can abut against the guide transmission part.

[0012] As an optional solution of the pushing mechanism with overload protection function, the guide transmission member is cylindrical, and the guide transmission member has a guide surface extending along the first direction, and the guide surface abuts against the end surface of the damping adjustment member.

[0013] As an optional solution of the pushing mechanism with overload protection function, the pushing assembly further includes an elastic member, which is located between the baffle and the pushing member, and the elastic deformation direction of the elastic member is the same as the first direction.

[0014] As an optional solution of the pushing mechanism with overload protection function, the elastic member is sleeved outside the guide transmission member.

[0015] As an optional solution for the pushing mechanism with overload protection function, the number of the guide transmission members is at least two, at least two of the guide transmission members are arranged at intervals along the second direction, and each of the guide transmission members is configured with the elastic member.

[0016] As an optional solution for the pushing mechanism with overload protection function, the driving assembly also includes a transmission plate and a limit plate. The transmission plate is used to be connected to the power source for transmission. The two limit plates are fixed to the transmission plate at intervals along the second direction to form a limit groove with a smaller upper part and a larger lower part. The slider is fixed to the transmission plate and matches the limit groove.

[0017] As an optional solution of the pushing mechanism with overload protection function, the baffle is fixedly connected to the end of the slider, and the baffle has a limiting protrusion, which is accommodated in the limiting groove and matches the limiting groove.

[0018] As an optional solution of the pushing mechanism with overload protection function, the pushing member includes a transmission part and a pushing part, the transmission part is provided with the through hole, and at least two of the pushing parts are fixed to the transmission part at intervals along the second direction.

[0019] In the second aspect, a stamping device is provided, including a power source, a stamping mechanism and a pushing mechanism with overload protection function as described above, wherein the power source is used to provide power to the stamping mechanism and the pushing mechanism, and the pushing mechanism is used to push out the product stamped by the stamping mechanism.

[0020] The beneficial effects of this application are:

[0021] The present application provides a pushing mechanism with an overload protection function, comprising a carrier, a drive assembly and a pushing assembly, wherein the drive assembly is used to drive the pushing assembly to move, and the pushing assembly has an overload protection function. When the battery jig is not stuck, the friction between the guide transmission member and the pushing member enables the pushing assembly as a whole to reciprocate along the first direction. When the battery jig is stuck, the guide transmission member can slide along the perforation relative to the pushing member. At this time, if the slider moves from the avoidance position to the pushing position, the baffle drives the guide transmission member to move relative to the pushing member along the first direction toward the direction of the pushing member under the action of the slider. If the slider moves from the pushing position to the avoidance position, the block drives the guide member to move relative to the pushing member along the first direction away from the pushing member under the action of the slider, thereby avoiding overload of the slider load to better protect the power source from being damaged.

[0022] The punching device provided in the present application uses the above-mentioned pushing mechanism to prevent the pushing mechanism from being overloaded due to the jamming of the battery fixture, thereby avoiding damage to the power source. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] 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.

[0036] 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.

[0037] In this application, the term "and / or" describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Additionally, the character " / " in this application generally indicates that the related objects are in an "and / or" relationship.

[0038] 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.

[0039] 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).

[0040] 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.

[0041] 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.

[0042] Figure 1 A schematic structural diagram of the stamping device provided in an embodiment of the present application is shown. Figure 2 The figure shows an exploded schematic diagram of the punching device provided in the embodiment of the present application. Figures 1 to 2 As shown, the stamping device includes a stamping mechanism 200 and a pushing mechanism 100. The stamping mechanism 200 is used to stamp the product, and the pushing mechanism 100 is used to push the product stamped by the stamping mechanism 200 out to facilitate the next stamping operation. It should be noted that the stamping device can be used for stamping the battery jig 300.

[0043] In this embodiment, the stamping mechanism 200 includes an upper mold 201 and a lower mold 202. The upper mold 201 and the lower mold 202 cooperate to achieve stamping and forming of the product. In addition, the power source of the stamping mechanism 200 and the power source of the pusher mechanism 100 are the same power source. Then, different transmission mechanisms are used to achieve the upper and lower opening and closing movement of the upper mold 201 of the stamping mechanism 200 and the linear pusher movement of the output end of the pusher mechanism 100.

[0044] The working process of the stamping device provided by the present application is as follows: when the upper mold 201 moves upward to open the mold, the output end of the pusher mechanism 100 moves along a first direction toward the stamping mechanism 200 and pushes out the stamped product; when the upper mold 201 moves downward to close the mold, the output end of the pusher mechanism 100 moves along the first direction away from the stamping mechanism 200 to avoid the upper mold 201. The first direction is the movement direction of the output end of the pusher mechanism 100.

[0045] In the related art, the pushing mechanism 100 and the punching mechanism 200 are mostly rigidly connected, and since the power source of the punching mechanism 200 is the same as the power source of the pushing mechanism 100, when the battery jig 300 gets stuck on the punching mechanism 200, the pushing mechanism 100 is easily overloaded due to the jamming of the battery jig 300, thereby causing damage to the power source.

[0046] In order to solve the above problems, the present application provides a pushing mechanism 100 with an overload protection function. When the battery fixture 300 gets stuck, the pushing mechanism 100 can be prevented from being overloaded, thereby protecting the power source of the stamping device from damage.

[0047] Figure 3 A structural schematic diagram of the material pushing mechanism 100 provided in an embodiment of the present application is shown. Figure 4 Shown Figure 3 A schematic cross-sectional view of the middle pushing mechanism 100 in one direction. Figure 5 Shown Figure 4 A partial enlarged view of the middle pushing mechanism 100. Figure 6 Shown Figure 3 A schematic cross-sectional view of the push mechanism 100 in another direction. Figures 3 to 6As shown, the pushing mechanism 100 includes a carrier 1, a drive assembly 2, and a pushing assembly 3. The drive assembly 2 includes a slider 21 for transmission connection with a power source. The slider 21 can reciprocate along a first direction relative to the carrier 1 and has a pushing position and an avoidance position. When the slider 21 moves from the avoidance position to the pushing position, the pushing assembly 3 can push the battery jig 300 stamped by the stamping mechanism 200 out of the stamping mechanism 200; when the slider 21 moves from the pushing position to the avoidance position, the pushing assembly 3 can avoid the upper mold 201 of the stamping mechanism 200, so that the upper mold 201 and the lower mold 202 cooperate to complete the stamping of the battery jig 300.

[0048] The pusher assembly 3 includes a baffle 31, a pusher member 32, and a guide transmission member 33. The baffle 31 is fixedly connected to the slider 21. The pusher member 32 has a through-hole 3211 extending in a first direction. One end of the guide transmission member 33 is fixedly connected to the baffle 31, and the other end is inserted into the through-hole 3211. The friction between the guide transmission member 33 and the wall of the through-hole 3211 is less than the maximum load of the power source. When the battery jig 300 is not stuck, the friction between the guide transmission member 33 and the pusher member 32 enables the pusher assembly 3 to reciprocate in the first direction. When the battery fixture 300 is stuck, the guide transmission member 33 can slide along the through hole 3211 relative to the pushing member 32. At this time, if the slider 21 moves from the avoidance position to the pushing position, the baffle 31 drives the guide transmission member 33 to move relative to the pushing member 32 along the first direction toward the direction of the pushing member 32 under the action of the slider 21. If the slider 21 moves from the pushing position to the avoidance position, the block drives the guide member to move relative to the pushing member 32 along the first direction away from the pushing member 32 under the action of the slider 21, thereby avoiding overload of the slider 21 and better protecting the power source from damage.

[0049] To adjust the friction between the guide transmission member 33 and the wall of the through-hole 3211, the pusher assembly 3 further includes a damping adjustment member 34. The pusher member 32 further has a threaded hole 3212 that communicates with the through-hole 3211. The damping adjustment member 34 is threadedly connected to the threaded hole 3212, and the end surface of the damping adjustment member 34 can abut against the guide transmission member 33. In this embodiment, the damping adjustment member 34 can be a cap screw. The damping adjustment member 34 can be rotated using a tool such as a wrench to improve operational convenience.

[0050] When it is necessary to increase the friction between the guide transmission member 33 and the wall of the through-hole 3211, the depth to which the damping adjustment member 34 is screwed into the threaded hole 3212 can be increased to increase the contact force between the damping adjustment member 34 and the guide transmission member 33, thereby increasing the friction between the guide transmission member 33 and the wall of the through-hole 3211. Conversely, when it is necessary to reduce the friction between the guide transmission member 33 and the wall of the through-hole 3211, the depth to which the damping adjustment member 34 is screwed into the threaded hole 3212 can be reduced to reduce the contact force between the damping adjustment member 34 and the guide transmission member 33, thereby reducing the friction between the guide transmission member 33 and the wall of the through-hole 3211.

[0051] The guide transmission member 33 has a guide surface 331 extending in the first direction. The guide surface 331 abuts the end surface of the damping adjustment member 34. This arrangement, on the one hand, increases the contact area between the guide transmission member 33 and the damping adjustment member 34 via the guide surface 331, thereby increasing the abutment force exerted by the damping adjustment member 34 on the guide transmission member 33. On the other hand, because the guide surface 331 extends in the first direction, the guide surface 331 provides a certain degree of guidance when the guide transmission member 33 moves in the first direction relative to the pusher 32 and the damping adjustment member 34.

[0052] Furthermore, the guide transmission member 33 also has a limiting surface 332 set at an angle to the guide surface 331 , and the limiting surface 332 can abut against the side wall of the guide transmission member 33 to limit the movement stroke of the guide transmission member 33 by using the limiting surface 332 .

[0053] The pusher assembly 3 further includes an elastic member 35, which is positioned between the baffle 31 and the pusher 32. The elastic member 35 is elastically deformed in the same direction as the first direction. The elastic member 35 provides preload to the pusher 32, allowing the movement of the baffle 31 to be smoothly transmitted to the pusher 32 when the load on the pusher 32 is small.

[0054] The elastic member 35 is sleeved outside the guide transmission member 33. This arrangement not only limits and guides the elastic member 35 to prevent the elastic member 35 from separating from the baffle 31 and the pusher 32, but also saves space. For example, the elastic member 35 can be a spring.

[0055] In this embodiment, there are two guide transmission members 33, which are spaced apart along the second direction. Each guide transmission member 33 is equipped with an elastic member 35, thereby ensuring that the pusher 32 is subjected to a balanced force. In other embodiments, the guide transmission members 33 and the elastic members 35 may be arranged in any number, such as three, four, or five groups, without limitation.

[0056] The pusher 32 includes a transmission portion 321 and a pusher portion 322. The transmission portion 321 defines a through-hole 3211. Three pusher portions 322 are fixed to the transmission portion 321 at intervals along the second direction. In other embodiments, the number of pusher portions 322 can be two, four, five, six, or any other number, without limitation. Furthermore, the pusher portions 322 can be removably secured to the transmission portion 321 using screws or other means, allowing for installation of an appropriate number of pusher portions 322 based on product size, thereby improving the applicability of the pusher 32.

[0057] The driving assembly 2 also includes a transmission plate 22 and a limit plate 23. The transmission plate 22 is used to be connected to the power source for transmission. The two limit plates 23 are fixed to the transmission plate 22 at intervals along the second direction and form a limit groove 230 that is smaller at the top and larger at the bottom. The slider 21 is fixed on the transmission plate 22 and matches the limit groove 230 to achieve the upper and lower direction limitation of the slider 21 through the limit groove 230 to ensure the stability of the slider 21.

[0058] Furthermore, the baffle 31 is detachably fixedly connected to the end of the slider 21, and the baffle 31 has a limiting protrusion 311, which is accommodated in and matches the limiting groove 230. The limiting groove 230 can limit the baffle 31 in the up and down directions, ensuring the stability of the movement of the baffle 31.

[0059] The above shows and describes the basic principles, main features and advantages of this application. Those skilled in the art should understand that the above embodiments do not limit this application in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the scope of protection of this application.
