[0028] The specific embodiments disclosed herein will now be described in detail with reference to the accompanying drawings.

[0029] like Figure 1 As shown, this disclosure provides a material frame 100 for placing workpieces. The material frame 100 includes: a base 101, which is flat and has a sliding groove 1011 with a preset extension length on its upper surface; and a plurality of adjusting members 102, which are disposed above the base 101 and are tunably connected to the sliding groove 1011. The plurality of adjusting members 102 and the base 101 form an open bearing cavity 105. The workpiece is placed in the bearing cavity 105, and any one or more of the adjusting members 102 can move in the sliding groove 1011 to adjust the length and / or width of the bearing cavity 105.

[0030] This solution provides a material frame 100 specifically designed for placing workpieces. The material frame 100 includes a base 101 and four adjusting members 102. Specifically, the base 101 is designed as a flat plate, and its upper surface is specially provided with sliding grooves 1011 of a predetermined extension length. These sliding grooves 1011 are key structures for realizing the function of the material frame 100. The four adjusting members 102 are arranged above the base 101, and together with the base 101, they form a square bearing cavity 105. This bearing cavity 105 has an opening to facilitate the placement of workpieces.

[0031] In use, the size of the supporting cavity 105 first needs to be adjusted according to the size of the workpiece to be placed. This is achieved by moving the adjusting member 102 within the sliding groove 1011 on the base 101. Moving the adjusting member 102 along the sliding groove 1011 changes the size of the supporting cavity 105 until it perfectly matches the size of the workpiece. Once adjusted, the workpiece can be placed into the adjusted supporting cavity 105. This design gives the material frame 100 high flexibility and adaptability, meeting the placement requirements of different workpieces. By moving the adjusting member 102 within the sliding groove 1011, the size of the supporting cavity 105 can be easily adjusted, thus achieving effective support and fixation for different workpieces.

[0032] Those skilled in the art will understand that the number of adjustment components 102 is not limited in this solution. It can be four as in the above-described embodiment, or three or five, as long as they can form a bearing cavity 105 that is adapted to the shape of the workpiece.

[0033] In one embodiment, the bearing cavity 105 is a square cavity, and the plurality of adjustment members 102 include four, which are respectively located around the bearing cavity 105, and all four adjustment members 102 are bent structures with a preset extension height.

[0034] In this design, the supporting cavity 105 is a square cavity surrounded by four adjusting members 102. Specifically, the four adjusting members 102 of the material frame 100 are designed to be spaced apart, and each adjusting member 102 has a bent structure with a preset extension height. These bent structures are specially designed with two interconnected sidewalls at right angles. Although the sidewalls of the supporting cavity 105 are not sealed in this design, the sidewalls of the four adjusting members 102 can limit the workpiece in four directions, thereby ensuring that the material frame 100 still has the function of supporting the workpiece.

[0035] In some embodiments, any one or two of the adjustment members 102 are plate-shaped structures with a preset extension height, and the remaining adjustment members are bent structures with a preset extension height.

[0036] In one specific implementation, any two adjacent adjusting members 102 are bent structures with a preset extension height, while the other two adjusting members 102 are plate-like structures with a preset extension height. That is, in this implementation, the structures of the four adjusting members 102 are not entirely identical; two adjacent adjusting members 102 are bent structures, while the other two are plate-like structures. When the workpiece is a battery core, the core is provided with tabs, which typically have positive and negative tabs. Therefore, to avoid obstructing the tabs on the battery core, two adjusting members 102 are set as plate-like structures.

[0037] like Figure 1 and Figure 2 As shown, in another specific embodiment, the three adjusting members 102 can also be configured as bent structures with a preset extension height, and one adjusting member 102 can be configured as a plate-like structure with a preset extension height. Since the number and position of the tabs on the stacked core are not the same, this configuration is also intended to avoid the tabs.

[0038] In one specific embodiment, the material frame 100 further includes at least two sliding plates 103 arranged opposite to each other along the length or width direction of the bearing cavity 105. The adjusting member 102 is adjustablely mounted on the sliding plate 103. The sliding plate 103 is located on the side of the adjusting member 102 away from the bearing cavity 105. The sliding plate 103 is slidably connected to the sliding groove 1011 to adjust the length or width of the bearing cavity 105.

[0039] The sliding plate 103 is provided with a through hole 1031 with a preset extension length. The extension direction of the through hole 1031 is perpendicular to the extension direction of the sliding groove 1011. The material frame also includes a plurality of corresponding fasteners and a plurality of locking elements. One end of the fastener is fixedly connected to the adjusting element 102, and the other end passes through the through hole 1031 and is connected to the locking element, so that the adjusting element 102 is adjustablely mounted on the sliding plate 103. The adjusting element 102 can slide along the through hole 1031 to adjust the width or length of the bearing cavity 105.

[0040] like Figure 1As shown, in this design, the material frame 100 also includes two sliding plates 103 arranged opposite each other along the length of the bearing cavity 105. One end of each sliding plate 103 is inserted into a sliding groove 1011 on the base 101 and slidably connected to the sliding groove 1011, while the other end extends upward. A slider is provided at the end of the sliding plate 103 connected to the base 101, and the slider is inserted into the sliding groove 1011 and slidably connected to the base 101. This structural design allows the slider to drive the sliding plate 103 to slide freely within the sliding groove 1011, thereby adjusting the length of the bearing cavity 105 to accommodate workpieces of different sizes.

[0041] In addition, two sliding plates 103 are provided on the side of the material frame 100 along its length, and each sliding plate 103 is provided with a through hole 1031 with a preset extension length. These through holes 1031 allow four adjusting members 102 to be installed on the sliding plate 103 and to slide along the through holes 1031, thereby adjusting the distance between two adjusting members 102 on the same sliding plate 103. Specifically, the material frame 100 is equipped with multiple corresponding fixing members and locking members, wherein one end of the fixing member is fixedly connected to the adjusting member 102, and the other end passes through the through hole 1031 and is connected to the locking member. During use, the fixing member drives the adjusting member 102 to move in the through hole 1031, thereby adjusting the size of the bearing cavity 105. More specifically, in this solution, the sliding plate 103 is located on the side of the adjusting member 102 away from the bearing cavity 105.

[0042] Those skilled in the art will understand that in other embodiments, the sliding plate 103 may also be arranged along the width direction of the bearing cavity 105, thereby enabling the length of the bearing cavity 105 to be adjusted to accommodate workpieces of different sizes.

[0043] It is worth noting that the through hole 1031 and the sliding groove 1011 in this design are perpendicular to each other. That is, if the sliding groove 1011 is set along the width direction of the material frame 100, then the through hole 1031 is set along the length direction of the material frame 100. This vertical layout makes the size adjustment of the material frame 100 more flexible and precise. During use, the width of the material frame 100 can be adjusted by controlling the two sliding plates 103 to move closer or further apart along the sliding groove 1011; similarly, the length of the material frame 100 can be adjusted by controlling the two or four adjusting pieces 102 oppositely arranged on the sliding plates 103 to move closer or further apart along the through hole 1031. This design allows the material frame 100 to adjust both its length and width simultaneously to accommodate workpieces of different lengths and widths, improving the applicability and ease of operation of the material frame 100.

[0044] Those skilled in the art will understand that, in different embodiments, the design of the material frame 100 allows for a configuration in which one sliding plate 103 is fixed to the base 101, while another sliding plate 103 is slidably connected to the base 101. Thus, the width of the material frame 100 can be adjusted by moving the other sliding plate 103 closer to or further away from the sliding plate 103 fixed to the base 101. The same principle applies to adjusting the length of the material frame 100. In another embodiment, two opposing adjusting members 102 can be fixed to two sliding plates 103 respectively, while two other adjusting members 102 are slidably connected to the sliding plates 103. By controlling these two slidably connected adjusting members 102 to move closer to or further away from the adjusting members 102 fixed to the sliding plates 103, the length of the material frame 100 can be adjusted.

[0045] In one specific implementation, the sliding plate 103 is provided with two through holes 1031 spaced apart along its horizontal direction. That is, in this solution, one adjusting member 102 corresponds to one through hole 1031. By distributing the through holes 1031 in this solution, the force borne by a single hole can be reduced, thereby improving the structural stability and durability of the sliding plate 103.

[0046] In some specific embodiments, both the sliding plate 103 and the adjusting member 102 have a preset extension height. The sliding plate 103 has at least two through holes 1031 arranged opposite to each other and parallel to each other along its preset extension height direction. The adjusting member 102 is adjustablely connected to the through holes 1031 through the fixing member and the locking member, so that the preset extension height direction of the adjusting member 102 is consistent with the preset extension height direction of the sliding plate 103, and the preset extension height direction is perpendicular to the extension direction of the through holes 1031 and the extension direction of the sliding groove, respectively.

[0047] In this design, both the sliding plate 103 and the adjusting member 102 have preset extension heights, and their extension height directions are consistent. Two or more through holes 1031 are spaced apart along the height direction on the sliding plate 103. Correspondingly, the adjusting member 102 also has mounting positions corresponding to the number of through holes 1031. The adjusting member 102 is adjustablely connected to the through holes 1031 via fixing members and locking members. By setting through holes 1031 at different heights, this design provides multiple fixing points for the adjusting member 102, thereby more firmly fixing the adjusting member 102 to the sliding plate 103 and preventing the adjusting member 102 from tilting in the height direction.

[0048] In addition, a second perforated portion 1033 is provided between two adjacent through holes 1031. This design not only saves materials but also reduces the overall weight of the frame 100, making it lighter.

[0049] It is worth noting that in this scheme, the preset extension height direction of the sliding plate 103 is perpendicular to the extension direction of the through hole 1031 and the extension direction of the sliding groove 1011.

[0050] In one specific implementation, to further reduce the overall weight of the material frame 100, this solution provides several first hollow portions 1012 spaced apart on the base 101. These first hollow portions 1012 reduce the weight of the material frame 100 while also reducing material usage and saving costs.

[0051] like Figure 2 As shown, in a specific embodiment, the material frame 100 further includes a reinforcing rib 104, the reinforcing rib 104 having a connecting hole 1041 extending in the same direction as the sliding groove 1011, the base fixing member at the sliding groove 1011 passing through the connecting hole 1041 and connected to the side wall of the sliding plate 103, the sliding plate 103 being able to slide along both the connecting hole 1041 and the sliding groove 1011 simultaneously.

[0052] In this design, the two sliding plates 103 are spaced apart and vertically supported on the base 101, resulting in poor stability. To improve the stability of the sliding plates 103, reinforcing ribs 104 are specially provided to connect the two sliding plates 103, thereby enhancing the overall stability of the sliding plates 103. Since the sliding plates 103 need to slide along the sliding groove 1011, connecting holes 1041 corresponding to the sliding groove 1011 are provided on the reinforcing ribs 104, allowing the sliding plates 103 to move smoothly along the sliding groove 1011 and the connecting holes 1041. To securely connect the sliding plates 103 and the reinforcing ribs 104, corresponding fasteners are also provided in the material frame 100. These fasteners can be bolts or other similar fixing structures or components, which pass through the connecting holes 1041 and connect to the side wall of the sliding plates 103, ensuring that the sliding plates 103 maintain a stable connection with the reinforcing ribs 104 while sliding. This design ensures the free sliding of the sliding plate 103 and improves the stability and reliability of the entire material frame 100 structure.

[0053] It is worth noting that, in order to enhance the structural stability of the sliding plate 103, two connecting ribs were specially designed, which are connected to both ends of the sliding plate 103 respectively. These connecting ribs are plate-shaped structures located in the middle region of the height direction of the sliding plate 103.

[0054] Those skilled in the art will understand that when one sliding plate 103 is fixed and the other sliding plate 103 is slidable, the configuration of the connecting hole 1041 on the reinforcing rib 104 will be adapted accordingly. Specifically, only the connecting hole 1041 connected to the slidable sliding plate 103 needs to be provided on the reinforcing rib 104. This design allows the fixed sliding plate 103 to remain stable, while the sliding plate 103 can slide along the reinforcing rib 104 through the connecting hole 1041, thereby adjusting the size of the material frame 100.

[0055] In some embodiments, a notch 1032 is provided on the side wall of the sliding plate 103, and the two end walls of the reinforcing rib 104 extending in the height direction abut against the upper and lower side walls of the notch 1032, respectively.

[0056] In this design, the reinforcing rib 104 is designed as a plate-like structure with a preset extension length and a preset extension width. The length direction of the reinforcing rib 104 is parallel to the extension direction of the sliding groove 1011, while its width direction is consistent with the extension direction of the adjusting member 102 (i.e., the height direction of the adjusting member 102). This design allows the reinforcing rib 104 to work effectively in conjunction with the sliding groove 1011 and the adjusting member 102.

[0057] To enhance the connection stability between the sliding plate 103 and the reinforcing rib 104, notches 1032 are specifically designed on the sidewall of the sliding plate 103. The extension length of these notches 1032 in the height direction of the sliding plate 103 is slightly greater than the width of the reinforcing rib 104, ensuring that the two end walls of the reinforcing rib 104 in the width direction can abut against the upper and lower sidewalls of the notches 1032, respectively. This structural design not only improves the connection stability but also helps to distribute forces and reduce local stress concentration, thereby enhancing the structural strength and durability of the entire frame 100. Through this carefully designed connection method, the frame 100 maintains its lightweight design while ensuring sufficient load-bearing capacity and stability.

[0058] In some embodiments, a scale mark is provided on the base 101 at the sliding groove 1011, and / or a scale mark is provided on the reinforcing rib 104 at the connecting hole 1041, and / or a scale mark is provided on the sliding plate 103 at the through hole 1031.

[0059] In this design, scale marks are provided on the base 101 at the sliding groove 1011, or on the reinforcing rib 104 at the connecting hole 1041. This design allows the user to more accurately determine the position of the adjusting member 102 by referring to these scale marks when adjusting the material frame 100. By referring to these scale marks, the user can easily adjust the width of the bearing cavity 105 to accommodate workpieces of different widths, ensuring that the setting of the material frame 100 is both accurate and efficient.

[0060] Those skilled in the art will understand that, in other embodiments, to improve the applicability and ease of operation of the material frame 100, scale markings can be simultaneously provided on both the base 101 and the reinforcing rib 104. By equipping both key structures with scale markings, the operator can easily read the dimensions from any angle, facilitating precise positioning when adjusting the material frame 100.

[0061] Those skilled in the art will understand that, in other embodiments, scale markings may also be provided on the sliding plate 103 at the through hole 1031. This design allows the user to more accurately determine the position of the adjusting member 102 by referring to these scale markings when adjusting the material frame 100. That is, by referring to these scale markings, the user can easily adjust the length of the bearing cavity 105 to accommodate workpieces of different lengths, ensuring that the setting of the material frame 100 is both accurate and efficient.

[0062] The material frame 100 disclosed herein possesses dual functions: adjusting both the length and width of the carrying cavity 105. This flexibility allows the material frame 100 to adapt to workpieces of different sizes. By precisely adjusting the dimensions of the carrying cavity 105, users can easily meet the placement requirements of workpieces of various sizes without needing to replace or use multiple material frames 100 of different specifications. This design not only improves the versatility of the material frame 100 but also greatly enhances the user experience by simplifying the operation process and reducing the additional workload caused by workpiece size mismatch.

[0063] In one specific implementation, the adjusting member 102 has a guide structure at the open end facing the bearing cavity 105. The guide structure is formed by an inclined surface, which is at an angle to the preset extension height direction and is inclined in a direction away from the open, so that the workpiece can be received into the material frame from the open.

[0064] In this design, to facilitate smoother entry of the workpiece into the bearing cavity 105 from the opening of the receiving cavity, a guide structure is provided at the end of the adjusting member 102 away from the base 101. Specifically, this guide structure is an inclined surface that forms an angle with the preset extension height direction of the adjusting member and is inclined away from the opening. That is, the inclined surface in this design has a first end and a second end at a height. The first end is located on the side wall of the adjusting member away from the bearing cavity 105, and the second end is located on the side wall surrounding the bearing cavity 105, with the height of the first end greater than the height of the second end. This arrangement ensures that when the workpiece enters the bearing cavity 105 from the opening, it will not be obstructed by the top wall of the adjusting member 102 and will enter the bearing cavity 105 more smoothly via the guide structure.

[0065] In a second aspect, this disclosure provides a die-cutting apparatus, the die-cutting apparatus including a conveying device and the aforementioned material frame 100, the conveying device conveying the workpiece and housing it in the material frame.

[0066] In some embodiments, a die-cutting apparatus is also provided, including the material frame 100 and conveying device as described in the above embodiments. In use, the conveying device transports the workpiece to the material frame, and the material frame collects the workpiece in preparation for the next operation.

[0067] The material frame 100 in this solution can adjust the length and width of the bearing cavity 105, thereby enabling it to bear workpieces of different sizes.

[0068] While numerous embodiments of this disclosure have been shown and described herein, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Many modifications, alterations, and alternatives will occur to those skilled in the art without departing from the spirit and intent of this disclosure. It should be understood that various alternatives to the embodiments of this disclosure described herein may be employed in the practice of this disclosure. The appended claims are intended to define the scope of this disclosure and therefore cover equivalents or alternatives within the scope of these claims.
