Description

Technical Field

[0001] The utility model belongs to the technical field of indentation molds, and in particular relates to an indentation mold. Background Art

[0002] When packaging new energy lithium batteries, soft pack packaging is one of the commonly used methods. When packaging square batteries, it is necessary to make an indentation on the aluminum film that matches the size of the square battery. The aluminum film with the indentation can be easily folded and wrapped on the square battery, which is convenient for the bonding and shaping of the aluminum film.

[0003] In actual production, most of the indentation molds are one-piece metal lines, and the indentation mold is fixed on the production machine. When forging aluminum film, the aluminum film is placed between the platform of the production machine and the indentation mold. The cylinder on the machine reciprocates to press the mold on the aluminum film to form an indentation. After forging, take it out and put in a new aluminum film to repeat the operation.

[0004] Due to the different sizes and protection levels of square batteries, the thickness of the aluminum film is also different. When the thickness of the aluminum film is large, the required indentation depth and width must be increased accordingly to facilitate folding. The existing mold can only indent one specification of aluminum film. Changing the indentation specification requires replacing the entire mold, which is very inconvenient to use and affects work efficiency. In addition, there is a risk of worker injury when repeatedly taking and placing the aluminum film.

[0005] Therefore, in view of the above technical problems, it is necessary to provide an indentation mold.

[0006] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0028] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0029] like Figure 1 and Figure 2As shown, an indentation mold in one embodiment of the utility model is installed on an indentation machine 1, and a conveyor belt 11 and a platform 12 are provided on the indentation machine 1, wherein the conveyor belt 11 is in two pairs, and the two pairs of conveyor belts 11 are symmetrically installed on the side wall of the indentation machine 1, and the upper end surface height of the platform 12 is equal to the belt surface height of the conveyor belt 11 on the lower side. The indentation mold includes a locking plate 2 and a mounting plate 6, and the locking plate 2 and the mounting plate 6 are square plates and welded to the upper ends of the opposite side walls of the indentation machine 1. A first rotating hole 21 is provided on the locking plate 2, and a second rotating hole 61 is provided on the mounting plate 6. A rotating rod 3 is rotatably connected in the first rotating hole 21 on the locking plate 2 and the second rotating hole 61 on the mounting plate 6, and the rotating rod 3 passes through the locking plate 2 and the mounting plate 6. A plurality of indentation components 4 are interference fit on the rotating rod 3, and a plurality of indentation balls 422 are rotatably connected on the indentation components 4, and the indentation balls 422 can forge the aluminum film on the platform 12. One end of the rotating rod 3 passing through the locking plate 2 is threadedly connected with a locking handle 5, and the locking handle 5 can lock the rotating rod 3, and the rotating rod 3 cannot rotate after being locked.

[0030] Specifically, when forging the aluminum film, the two pairs of conveyor belts 11 clamp the aluminum film and drive the aluminum film to move toward the discharge end of the indentation machine 1. When the aluminum film passes under the indentation assembly 4, the indentation ball 422 on the indentation assembly 4 is indented. Because the indentation ball 422 is rotatably connected to the indentation assembly 4, when the aluminum film passes through the indentation ball 422, the worker does not need to repeatedly pick up the aluminum film to adjust the position of the aluminum film on the platform 12. The indentation ball 422 can forge the aluminum film sliding on the platform 12, saving working time.

[0031] Furthermore, because the reciprocating indentation die for forging the aluminum film is fixedly mounted on the indentation machine 1, there is no need to manually take and place the aluminum film repeatedly between the indentation machine 1 and the forging die, which greatly reduces the risk of worker injury.

[0032] like Figures 1 to 4 As shown, in order to forge indentations of different widths for aluminum films of different thicknesses, four connecting blocks 41 are provided on the indentation assembly 4, and the four connecting blocks 41 are evenly distributed on the indentation assembly 4, and two adjacent connecting blocks 41 are perpendicular to each other. An adjusting column 42 is installed on the connecting block 41, and an indentation ball 422 is rotatably connected to the end surface of the adjusting column 42 away from the connecting block 41, and the indentation balls 422 on different adjusting columns 42 have different diameters.

[0033] Specifically, the indentation ball 422 is connected to the adjustment column 42 in a bull's eye universal wheel structure, and the indentation ball 422 can be rotated on the adjustment column 42 without falling. When indentations of different widths are required, an indentation ball 422 with a suitable diameter is selected, and the rotating rod 3 is rotated to make the adjustment column 42 where the suitable indentation ball 422 is located perpendicular to the platform 12.

[0034] Furthermore, when the thickness of the aluminum film is large, the required indentation depth will also increase. A second internal thread 411 is provided on the connecting block 41, and a second external thread 421 matching the second internal thread 411 is provided on the adjusting column 42. The adjusting column 42 and the connecting block 41 are connected together through threads. The depth of the indentation can be controlled by rotating the adjusting column 42 to adjust the length of the adjusting column 42 exposed from the connecting block 41.

[0035] like Figure 2 , Figure 5 and Figure 6 As shown, in order to lock the adjustment column 42 in the vertical direction, a fixing groove 22 is provided on the inner side wall of the locking plate 2. The fixing groove 22 is cross-shaped, and the center position of the fixing groove 22 coincides with the first rotating hole 21 and is penetrated by the first rotating hole 21. A protrusion 31 matching the fixing groove 22 is provided on the rotating rod 3, and the protrusion 31 is clamped in the fixing groove 22. A locking handle 5 is threadedly connected to the end surface of the rotating rod 3 exposed from the locking plate 2, and a blocking piece 51 is welded on the locking handle 5. The blocking piece 51 and the protrusion 31 clamp the locking plate 2, so that the rotating rod 3 cannot rotate.

[0036] Specifically, a first external thread 32 is provided at one end of the rotating rod 3, and a first internal thread 52 is provided at one end of the locking handle 5 connected to the rotating rod 3. The locking handle 5 is continuously rotated, and the locking handle 5 moves linearly on the rotating rod 3 under the action of the tightening force, and finally the blocking piece 51 on the locking handle 5 abuts against the outer wall of the locking plate 2. Because the protrusion 31 on the rotating rod 3 is clamped in the fixing groove 22 on the inner wall of the locking plate 2, the blocking piece 51 abuts against the outer wall of the locking plate 2, and the protrusion 31 cannot be separated from the fixing groove 22, so the rotating rod 3 can be locked.

[0037] When the aluminum film is forged, the indentation assembly 4 will vibrate. In order to prevent the vibration from causing the connection between the locking handle 5 and the rotating rod 3 to loosen, an elastic block 33 is threadedly connected to the end of the rotating rod 3 that is exposed from the outer wall of the mounting plate 6. When the first external thread 32 is clamped in the fixing groove 22, the elastic block 33 also fits the outer wall of the mounting plate 6. After tightening the locking handle 5, the rebound force of the elastic block 33 can strengthen the friction between the baffle 51 on the locking handle 5 and the side wall of the locking plate 2, so that the connection between the locking handle 5 and the rotating rod 3 is stable.

[0038] Preferably, the outer wall surface of the locking plate 2 has burrs, which can increase the friction between the blocking piece 51 and the locking plate 2 .

[0039] like Figure 1 , Figure 4 and Figure 6As shown, the fixing groove 22 , the protrusion 31 and the connecting block 41 are parallel to each other in the horizontal and vertical directions. When the protrusion 31 is inserted into the fixing groove 22 , there will be a connecting block 41 perpendicular to the upper end surface of the forging platform 12 .

[0040] When in use, insert the whole aluminum film onto two sets of conveyor belts 11, start the conveyor belts 11, and the conveyor belts 11 transport the aluminum film into the creasing machine 1. After the aluminum film passes through the vertical adjusting column 42, it is forged by the creasing ball 422 on the adjusting column 42, and then transported out from the discharge end of the creasing machine 1 by the conveyor belts 11.

[0041] When the depth of the indentation of the aluminum film needs to be adjusted, the adjusting column 42 is rotated to extend or retract the adjusting column 42 in the connecting block 41 , and the depth of the indentation is controlled by adjusting the extended length of the adjusting column 42 .

[0042] When the width of the indentation needs to be adjusted, the locking handle 5 is rotated to move the baffle 51 away from the locking plate 2, and the locking handle 5 is pushed toward the mounting plate 6 to make the protrusion 31 disengage from the fixing groove 22, and then the locking handle 5 is rotated to select the indentation ball 422 with a suitable diameter, so that the adjustment column 42 connected to the indentation ball 422 is perpendicular to the platform 12. The locking handle 5 is pulled, and the protrusion 31 will enter the fixing groove 22. At this time, the locking handle 5 is rotated to make the baffle 51 on the locking handle 5 fit the outer wall of the locking plate 2, and the locking handle 5 is continued to be rotated, so that the protrusion 31 can be firmly clamped in the fixing groove 22, thereby locking the elastic block 33 and preventing it from rotating.

[0043] When only one indentation is required on the aluminum film, the adjusting column 42 can be rotated and locked in the connecting block 41 so that the indentation ball 422 in the connecting block 41 does not contact the aluminum film. Only the distance between the adjusting column 42 and the platform 12 needs to be adjusted so that the indentation ball 422 on the adjusting column 42 can make an indentation on the aluminum film. Using the same operation steps, multiple indentations can be made on the aluminum film according to production needs.

[0044] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0045] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
