Description

Technical Field

[0001] The utility model relates to the technical field of coil processing, in particular to an automatic punching machine. Background Art

[0002] With the increasing development of new energy vehicles, in order to meet the energy and voltage requirements of electric vehicles, its power battery system is composed of single or multiple battery packs. Generally speaking, each battery pack is composed of several battery modules, and each battery module is composed of several single cells. Usually, several single cells are connected in series and parallel to form a battery module, and then the battery module is bundled and tightened with a steel strip to form a complete battery module. The steel strip is continuously stamped from a metal coil. The stamping process is usually operated by a punching press. At present, most of the punching processes are manual operations. The coil is punched on the punching press through a customized die, and then the punched steel strip is cut to the same length by means of manual feeding and manual positioning.

[0003] The above processing method has a high dependence on manual labor, low processing efficiency, and during the punching process, manual positioning of the coil is required. Thus, there are relatively large safety hazards, waste of labor costs, low production efficiency, and high comprehensive production costs. Summary of the Utility Model

[0004] In order to overcome the shortcomings in the prior art, the purpose of the utility model is to provide an automatic punching machine.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An automatic punching machine, comprising a base and a punching machine fixed on the base. The punching machine includes a feeding mechanism, a conveying and positioning mechanism, a length detection mechanism, a fixed pressing machine, and a punching mechanism. The feeding mechanism and the length detection mechanism are both fixedly connected to the base. The conveying and positioning mechanism is fixedly connected to the base and is arranged on both sides of the length detection mechanism. The fixed pressing machine is fixedly connected to the base and is arranged on the right side of the conveying and positioning mechanism. The punching mechanism is fixedly connected to the base and is arranged on the right side of the fixed pressing machine. A conveying channel is fixedly connected between the fixed pressing machine and the punching mechanism. An outlet is arranged on one side of the punching mechanism.

[0007] Compared with the prior art, the automatic punching machine of the present application has the following beneficial effects:

[0008] In actual application, when the coiled stainless steel strip is conveyed to the length detection mechanism through the feeding mechanism and the conveying and positioning mechanism, the servo motor cooperates with the length detection mechanism to send out the accurate length of the steel strip into the punching mechanism part. The punching mechanism can complete the punching of the steel strip length. The punching power uses the servo motor for punching, and the punching is very stable with little noise. The equipment also has the function of convex point stamping for projection welding. The standard configuration is to punch 6 convex points. Other numbers of convex points can also be achieved by replacing the mold.

[0009] Preferably, the length detection mechanism includes a detection base, a bearing seat, a first motor and a driving roller. The detection base is fixedly connected to the base. First through holes are formed on both sides of the detection base. The bearing seat is connected in the first through hole. Both ends of the driving roller are rotatably connected to the bearing seat. The output end of the first motor passes through the first through hole and is connected to the driving roller.

[0010] Beneficial effects: The driving roller is driven to rotate by the first motor, so that the coiled stainless steel strip is conveyed through two horizontally arranged driving rollers. The first motor cooperates with the controller to detect the length of the feeding amount of the coiled stainless steel strip, thereby improving the punching accuracy.

[0011] Preferably, the conveying and positioning mechanism includes a support base, a vertical limiting wheel and a horizontal limiting wheel. Vertical limiting columns and horizontal limiting columns are fixedly arranged on the support base. The vertical limiting wheel is rotatably connected to the vertical limiting column, and the horizontal limiting wheel is rotatably connected to the horizontal limiting column.

[0012] Beneficial effects: The conveying and positioning mechanism limits and fixes the up-and-down displacement position and left-and-right displacement position of the coiled stainless steel strip by arranging multiple groups of vertical limiting wheels and horizontal limiting wheels, reduces the displacement deviation of the stainless steel strip during conveying, and improves the conveying and detection accuracy of the subsequent length detection mechanism.

[0013] Preferably, a first sliding groove is formed on the support base. A first sliding block and an adjusting stud are arranged in the first sliding groove. An adjusting hole is formed on the first sliding block. The first sliding groove is slidably connected to the first sliding block. The adjusting stud passes through the adjusting hole and is connected to the first sliding groove.

[0014] Beneficial effects: By forming a first sliding groove on the support base, the feeding width of the conveying and positioning mechanism can be adjusted according to the width of the stainless steel strip to ensure that the vertical limiting wheels always remain on both sides of the stainless steel strip.

[0015] Preferably, the fixed pressing machine includes a pressing base, a second motor, a motor fixing base, a fixed pressing plate and a fixed bottom plate. The pressing base is fixedly connected to the base. A limiting groove is formed in the pressing base. The fixed bottom plate is fixedly connected in the limiting groove. The motor fixing base is fixedly connected to the top of the pressing base. A second through hole and a third through hole are formed in the motor fixing base. The second motor is fixedly connected to the motor fixing base. The output end of the second motor passes through the third through hole and is fixedly connected to the fixed pressing plate. A guiding column is fixedly arranged on the fixed pressing plate. The guiding column is slidably connected to the second through hole. A steel belt fixing groove is formed in the fixed bottom plate.

[0016] Beneficial effects: When the length detection mechanism conveys the steel belt of a specified length into the punching mechanism, the second motor above the fixed pressing machine drives the fixed pressing plate to press down to the fixed bottom plate, so that the stainless steel belt is fixed in the steel belt fixing groove and is not easy to move, facilitating the subsequent punching mechanism to perform punching bumps and punching operations.

[0017] Preferably, the punching mechanism includes a die base, a third motor, a punching die and a die connecting member. The die base is fixedly connected to the base. A discharge port is fixedly formed on the right side of the die base. A punching groove is formed in the die base. The third motor is fixedly connected to the die base and is arranged on the top of the punching groove. The top of the die connecting member is fixedly connected to the output end of the third motor. The bottom of the die connecting member is connected to the punching die. The die connecting member and the punching die are both arranged in the punching groove. A punching bump and a punching cutter are arranged at the bottom of the punching die. A punching concave point is further formed at the bottom of the punching groove.

[0018] Beneficial effects: By driving the punching die to press down by the third motor, the stainless steel belt fixed in the punching groove is punched into a preset length by the punching die. The punching is very stable, with low noise, and continuous operation can be carried out.

[0019] Preferably, a punching sliding groove is formed in the die connecting member. A punching sliding block is fixedly arranged at the top of the punching die. The punching sliding groove is slidably connected to the punching sliding block.

[0020] Beneficial effects: By arranging the punching sliding groove and the punching sliding block to be slidably connected, when the die connecting member presses down, it can abut against the punching sliding block to punch the stainless steel belt. After punching is completed, the die connecting member rises to drive the punching die to rise. At this time, the length detection mechanism conveys the stainless steel belt to eject the punched steel belt out of the discharge port for the next punching operation.

[0021] Preferably, the feeding mechanism includes a feeding base, a dust removal brush, and a brush fixing seat. The feeding base is fixedly connected to the base, the brush fixing seat is fixedly connected to the feeding base, and the dust removal brush is fixedly connected to the brush fixing seat.

[0022] Beneficial effects: By arranging a dust removal brush at the front end of the feeding mechanism, dirt on the surface of the steel strip can be cleaned when the steel strip enters the punching machine, ensuring the accuracy of subsequent length detection by the length detection mechanism.

A conveying channel 7 is fixedly connected between the fixed pressing machine 5 and the punching mechanism 6. A discharge port 8 is arranged on one side of the punching mechanism 6.

[0037] Specifically, by setting the length detection mechanism 4 to precisely control the feeding amount of the stainless steel belt 46, it is ensured that the length of the stainless steel belt 46 punched by the punching mechanism 6 each time is the same, reducing the positioning steps required for manual punching and improving the production efficiency and processing accuracy.

[0038] The length detection mechanism 4 of this embodiment includes a detection base 9, a bearing seat 10, a first motor 11 and a driving roller 12.

Both ends of the driving roller 12 are rotatably connected to the bearing seats 10. The output end of the first motor 11 passes through the first through hole 13 and is connected to the driving roller 12.

[0039] Specifically, two driving rollers 12 are rotatably fixed up and down on the detection base 9. The stainless steel belt 46 passes through the middle of the two driving rollers 12 and abuts against them. When the first motor 11 drives the driving rollers 12 to rotate, the stainless steel belt 46 can be conveyed to the fixed pressing machine 5, and the feeding length each time is controlled by the first motor 11.

[0040] The conveying and positioning mechanism 3 of this embodiment includes a support base 14, a vertical limiting wheel 15 and a horizontal limiting wheel 16.

[0041] Specifically, two sets of conveying and positioning mechanisms 3 are arranged on the conveying line of the punching machine to position and support the stainless steel belt 46. By arranging multiple sets of vertical limiting wheels 15 and horizontal limiting wheels 16, the left and right positions and height of the stainless steel belt 46 during conveying are limited to ensure the position accuracy from the feeding mechanism 2 to the length detection mechanism 4.

[0042] A first sliding groove 19 is formed on the support base 14 of this embodiment. A first sliding block 20 and an adjusting screw column 21 are arranged in the first sliding groove 19. An adjusting hole 22 is formed on the first sliding block 20. The first sliding groove 19 is slidably connected to the first sliding block 20, and the adjusting screw column 21 passes through the adjusting hole 22 and is connected to the first sliding groove 19.

[0043] Specifically, through the sliding connection between the first sliding groove 19 and the first sliding block 20, the distance between the two vertical limiting wheels 15 can be adjusted according to the width of the stainless steel belt 46 in actual production.

[0044] The fixed pressing machine 5 of this embodiment includes a pressing base 23, a second motor 24, a motor fixing base 25, a fixed pressing plate 26 and a fixed bottom plate 27.

A steel belt fixing groove 32 is formed on the fixed bottom plate 27.

[0045] Specifically, when the stainless steel belt 46 is conveyed to the fixed pressing machine 5, the second motor 24 presses down the fixed pressing plate 26 to make it abut against the fixed bottom plate 27. At this time, the stainless steel belt 46 is fixed in the steel belt fixing groove 32 and is not easy to move, which is convenient for completing the stamping and punching process in the tail-end punching mechanism 6 and improves the punching accuracy.

[0046] The punching mechanism 6 of this embodiment includes a die base 33, a third motor 34, a punching die 35, and a die connecting member 36. The die base 33 is fixedly connected to the base 1. An outlet 8 is fixedly opened on the right side of the die base 33. A punching groove 37 is opened on the die base 33.

[0049] Specifically, through the mutual sliding connection of the punching chute 41 and the punching slider 42, when the third motor 34 drives the die connecting member 36 to rise, the punching die 35 can be driven to lift, facilitating the feeding of the stainless steel strip 46 by the length detection mechanism 4 for punching operations. When the third motor 34 drives the die connecting member 36 to press down, the punching die 35 punches and cuts the stainless steel strip 46 at the bottom.

[0050] The feeding mechanism 2 of this embodiment includes a feeding base 43, a dust removal brush 44, and a brush fixing seat 45. The feeding base 43 is fixedly connected to the base 1.
