Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal stamping, more particularly to a feeding stamping and stacking system. BACKGROUND

[0002] Metal aluminum foil stamping parts are widely used in the electronic, packaging and other industrial fields, but they are thin, brittle and easily deformed, which are easily damaged in production, which puts high requirements on the discharge and stacking of stamping parts. The mainstream stacking system has obvious technical shortcomings when dealing with this challenge.

[0003] The existing technical solutions are mainly divided into two categories, both of which are difficult to balance efficiency, cost and quality. One is gravity feeding type stacking. This scheme relies on the weight of the workpiece after stamping to make it pass through the slide or directly fall into the stacking area. Although this method is simple in structure, its core defect is the unavoidable impact of falling. After the workpiece is separated from the mold, it will hit the workpiece or the bottom of the basket at a certain speed. This instantaneous impact force is enough to cause the edge of the aluminum foil to curl, the surface to appear indentation or the whole to deform. As the number of stacked layers increases, the pressure on the bottom layer of workpieces continues to increase, and the damage is further aggravated, which seriously restricts the final yield of the product.

[0004] The second is the mechanical arm handling type stacking. In order to overcome the impact problem of gravity feeding, some systems use industrial robots for grabbing and handling. However, this scheme introduces new problems. The first disadvantage is the contradiction between efficiency and cost. In order to achieve soft grabbing, the motion trajectory, speed of the mechanical arm and the adsorption force or clamping force of the end effector need to be programmed and controlled very finely, which greatly increases the complexity and cycle of system debugging. At the same time, the investment cost of industrial robots and their high-precision end effectors is high. Under the production rhythm of high-speed stamping, the repeated taking and placing action of the mechanical arm often becomes the bottleneck of the overall production efficiency, resulting in low equipment utilization, which is difficult to meet the dual needs of efficiency and cost in large-scale production.

[0005] In summary, gravity feeding type cannot overcome the physical impact to damage the quality, and mechanical arm handling type is difficult to popularize due to low efficiency and high cost. Therefore, an innovative solution is urgently needed to realize the lossless and smooth transfer of the whole process of aluminum foil stamping part discharge and stacking without sacrificing production efficiency and economy. In view of this, we propose a feeding stamping and stacking system. SUMMARY

[0048] Example 1: As Figures 2 to 14 As shown, the present invention relates to a feeding, stamping and palletizing system, including an uncoiling feeding mechanism 1, a stamping mechanism 2 at the output end of the uncoiling feeding mechanism 1, a belt conveyor 3 at the end of the stamping mechanism 2 away from the uncoiling feeding mechanism 1, a correction frame 4 on the belt conveyor 3, a palletizing mechanism 5 at the end of the belt conveyor 3 away from the stamping mechanism 2, and a blowing mechanism 6 on the stamping mechanism 2.

[0049] The palletizing mechanism 5 includes a palletizing frame 501, a fixed plate 502, a floating component 503, a synchronous rotating group 504, a drive unit 505, a rocker assembly 506, a material feeding chassis 507, and an air injection unit 508. The palletizing frame 501 is located at the end of the belt conveyor 3 away from the stamping mechanism 2. The fixed plate 502 is symmetrically arranged on the palletizing frame 501. The floating component 503 is connected to the bottom end of the fixed plate 502. The synchronous rotating group 504 is located on the fixed plate 502. The drive unit 505 is located at the top end of the palletizing frame 501. One end of the rocker assembly 506 is connected to the synchronous rotating group 504, and the other end of the rocker assembly 506 is connected to the floating component 503. The material feeding chassis 507 is located at the bottom end of the palletizing frame 501, and the air injection unit 508 is located on the outside of the palletizing frame 501.

[0050] The air injection unit 508 is connected to the unloading chassis 507 and supplies air to the floating component 503, so that the stamped parts are stacked in a buffered state. The floating component 503 can adjust its effective buffer support area to adapt to stamped parts of different sizes and avoid the decline in stacking quality caused by impact.

[0051] In this invention, aluminum foil rolls are unwound and fed by unwinding feeding mechanism 1 and conveyed to stamping mechanism 2 for stamping and forming; the stamped workpiece is blown away from the mold by blowing mechanism 6 and falls onto belt conveyor 3; belt conveyor 3 conveys the workpiece to the end, and after being guided by correction frame 4, it enters the working area of ​​stacking mechanism 5.

[0052] The palletizing process is as follows: The air injection unit 508 is started, and the airflow is conveyed upward through the unloading chassis 507, and finally overflows evenly from the effective buffer support area formed by the floating component 503, forming an air-buffered support layer above it. When the workpiece is sent into this area, it is in a buffered state under the action of the airflow, thereby effectively avoiding the hard impact and friction between the workpiece and the mechanical structure during the initial acceptance, and greatly protecting the surface quality and geometry of the vulnerable workpiece.

[0053] When the next workpiece needs to be stacked, the air blower set 508 will instantaneously reduce or close the air flow, the buffer support force disappears, and the buffered workpiece will land extremely smoothly and slowly on the workpiece or the blanking bottom disc 507 that has been stacked below, achieving soft landing. This completely solves the deformation and damage problems caused by high-speed impact of workpieces in the traditional gravity blanking mode.

[0054] At the same time, the driving unit 505 drives the synchronous rotating group 504 to drive the rocker assembly 506 to act, so as to accurately adjust the expansion diameter of the floating assembly 503, change the size of the effective buffer support area, and match different sizes of stamping parts. This design enables a single device to flexibly adapt to various product specifications without the need to replace hardware, significantly improving the universality and production efficiency of the device, and overcoming the bottleneck of high cost and slow beat of the mechanical arm conveying mode.

[0055] In the embodiment of the present application, the stacking frame 501 comprises a bottom plate 5011, a top plate 5012, a support column 5013, a bottom hole 5014 and a top hole 5015, the bottom plate 5011 is arranged on two blanking bottom discs 507, the support column 5013 is arranged at the top end of the bottom plate 5011, the top plate 5012 is arranged at the top end of the support column 5013, the top hole 5015 is symmetrically arranged on the top plate 5012, the bottom hole 5014 is symmetrically arranged on the bottom plate 5011, the fixed disc 502 is fixedly hoisted at the bottom end of the bottom hole 5014, the driving unit 505 is arranged on the top plate 5012, the deviation rectifying frame 4 is fixedly arranged at the position of the top plate 5012 located at the top hole 5015, and the diameter of the top hole 5015 is greater than that of the bottom hole 5014.

[0056] In the present application, the bottom plate 5011 is arranged on the blanking bottom disc 507 to provide a mounting base for the core mechanism. The support column 5013 and the top plate 5012 jointly constitute a high-rigidity support frame, which effectively ensures the stability of the positions of various components during stacking, and provides a basis for precise buffering and stacking.

[0057] In the embodiment of the present application, the fixed disc 502 comprises a disc body 5021, a cylinder body 5022, an inner tooth ring 5023 and a sliding groove 5024, the disc body 5021 is fixedly hoisted at the bottom end of the top hole 5015, the cylinder body 5022 is fixedly connected to the bottom end of the disc body 5021, the inner tooth ring 5023 is rotatably arranged at the bottom end of the disc body 5021, the sliding groove 5024 is annularly and equidistantly arranged on the cylinder body 5022, and the synchronous rotating group 504 is connected to the cylinder body 5022 and the disc body 5021.

[0058] In the present application, when the driving unit 505 drives the inner tooth ring 5023 to rotate, power is transmitted through the synchronous rotating group 504 engaged therewith, and finally converted into the synchronous and stable radial movement of all expansion and contraction blocks 5042 along the sliding groove 5024.

[0059] As another embodiment of the application, the floating assembly 503 comprises flexible inclined plate A 5031, flexible inclined plate B 5032, vertical plate A 5033, vertical plate B 5034, fixed rod 5035, sleeve ring 5036 and insertion rod 5037, the flexible inclined plate A 5031 and the flexible inclined plate B 5032 are connected in a ring shape at the bottom end of the cylinder 5022, the flexible inclined plate A 5031 and the flexible inclined plate B 5032 partially overlap and contact, the vertical plate A 5033 is connected to the bottom end of the flexible inclined plate A 5031, the vertical plate B 5034 is connected to the bottom end of the flexible inclined plate B 5032, the vertical plate A 5033 and the vertical plate B 5034 partially overlap and contact, the fixed rod 5035 is symmetrically fixed to the vertical plate B 5034, the sleeve ring 5036 is fixed to the end of the fixed rod 5035 away from the vertical plate B 5034, the insertion rod 5037 is symmetrically fixed to the vertical plate A 5033, and the end of the insertion rod 5037 away from the vertical plate A 5033 is movably inserted into the sleeve ring 5036, and one end of the rocker assembly 506 is fixed to the vertical plate A 5033.

[0060] In the application, the flexible inclined plate A 5031 and the flexible inclined plate B 5032 are connected at the bottom end of the cylinder 5022 and arranged in a ring shape, partially overlap and contact, and together form a conical fairing that can expand and contract radially.

[0061] When the rocker assembly 506 pulls or pushes the vertical plate A 5033, the power is transmitted to the insertion rod 5037 through the sliding fit and limiting in the sleeve ring 5036, and the sleeve ring 5036 is fixed to the vertical plate B 5034 through the fixed rod 5035. This design ensures that all vertical plates A 5033 and vertical plates B 5034 and the corresponding flexible inclined plates A 5031 and flexible inclined plates B 5032 above can expand or contract radially synchronously and smoothly, realizing continuous and stable adjustment of the diameter of the buffer area of the floating assembly 503.

[0062] At the same time, the flexible inclined plate A 5031 and the flexible inclined plate B 5032, and the vertical plate A 5033 and the vertical plate B 5034 always maintain a partially overlapping and contacting state. This design ensures that the entire floating assembly 503 maintains effective sealing and shielding in the circumferential direction during dynamic adjustment, ensuring that the airflow introduced from below is constrained inside the assembly to form a stable air cushion, and will not leak in large quantities from the assembly joints, thereby ensuring the reliability and uniformity of the buffering effect.

[0063] As another embodiment of the present application, the synchronous rotating group 504 comprises a gear 5041, an expansion block 5042, an air pipe 5043, a tooth slot 5044 and a tapered pipe 5045. The gear 5041 is arranged on the disc body 5021 in a ring shape and rotates at equal intervals. The expansion block 5042 is movably inserted into the sliding groove 5024. The air pipe 5043 is fixedly arranged at one end of the expansion block 5042. The tapered pipe 5045 is fixedly arranged at the other end of the expansion block 5042. The tooth slot 5044 is arranged on the expansion block 5042 and is connected with the gear 5041. The gear 5041 is also connected with the inner tooth ring 5023.

[0064] In the present application, when the driving unit 505 drives the inner tooth ring 5023 to rotate, power is synchronously transmitted to all tooth slots 5044 on the expansion blocks 5042 through the gear 5041, so as to force the plurality of expansion blocks 5042 to move radially along the sliding groove 5024 accurately and synchronously, thereby realizing efficient and unified transmission of power to the execution unit.

[0065] The air pipe 5043 is fixedly arranged at one end of the expansion block 5042 and is used for connecting compressed gas from the air compressor 508. When the stamping part falls, the system controls the air flow to enter the air pipe 5043 and blow upwardly through the tapered pipe 5045 fixedly arranged at the other end of the expansion block 5042. The main function of the air flow is not to lift the workpiece throughout the buffer, but to form an upward force under the workpiece in the initial stage of falling of the workpiece, so as to offset the kinetic energy of falling of the workpiece, thereby significantly slowing down the falling trend and speed of the workpiece and realizing soft unloading.

[0066] In the embodiment of the present application, the driving unit 505 comprises a motor 5051, a driving wheel 5052 and a belt 5053. The motor 5051 is fixedly arranged on the top plate 5012. The driving wheel 5052 is fixedly sleeved on the output end of the motor 5051. One end of the belt 5053 is sleeved on the driving wheel 5052.

Power is transmitted through the belt 5053 and drives the inner tooth ring 5023 to rotate. The power of the motor 5051 is transmitted to the inner tooth ring 5023 through the belt 5053. This transmission mode runs stably, has low noise and has certain overload protection capacity, so as to ensure stable and reliable operation of the system.

[0068] In the embodiment of the present application, the rocker assembly 506 comprises a locking frame 5061, a connecting rod 5062, an adapter frame 5063, a rocker 5064 and a rocker seat 5065, the locking frame 5061 is fixedly connected to the outer wall of the vertical plate A 5033, the connecting rod 5062 is connected to the locking frame 5061, the rocker seat 5065 is fixedly arranged on the outer wall of the bottom end of the cylinder 5022 in a ring shape at equal intervals, the rocker 5064 is rotatably connected to the rocker seat 5065, one end of the rocker 5064 is hingedly connected to the bottom end of the expansion and contraction block 5042, the other end of the rocker 5064 is fixedly connected to the adapter frame 5063, and the end of the adapter frame 5063 away from the rocker 5064 is hingedly connected to the end of the connecting rod 5062 away from the locking frame 5061.

[0069] In the present application, the rocker 5064 is installed on the cylinder 5022 through the rocker seat 5065, one end of the rocker 5064 is hingedly connected to the expansion and contraction block 5042, and the other end of the rocker 5064 is connected to the locking frame 5061 through the adapter frame 5063 and the connecting rod 5062, and the locking frame 5061 is fixed on the vertical plate A 5033.

[0070] When the expansion and contraction block 5042 moves radially in a small stroke under the driving of the synchronous rotating group 504, the small stroke radial movement is converted into a large stroke swing of the end of the connecting rod 5062 through the lever action of the rocker 5064 on the rocker seat 5065, which not only ensures the accuracy of adjustment, but also realizes a sufficient adjustment range, ensuring that the system can effectively adapt to workpieces of different sizes.

[0071] As another embodiment of the present application, the blanking bottom disc 507 is provided with a ventilation square tube 5071 at one end, the other end of the blanking bottom disc 507 is provided with a discharge port 5072, and the outer wall of the blanking bottom disc 507 is rotatably provided with a blocking frame 5073.

[0072] In the present application, the blocking frame 5073 realizes the opening and closing of the discharge port 5072 through rotation. When the stacking operation is performed, the blocking frame 5073 closes the discharge port 5072, ensuring that a closed air chamber is formed in the blanking bottom disc 507, so that the airflow can be concentrated and upwardly conveyed, ensuring the normal progress of the buffering and stacking process; when the stacking reaches a predetermined number, the blocking frame 5073 is rotated to be opened, so that the workpiece group can be smoothly discharged from the discharge port 5072, realizing continuous production.

[0074] The fan 5081 generates the required air flow, which is stably delivered to the ventilation square pipe 5071 through the air delivery pipe 5082, to provide a continuous and reliable air source for the entire buffer stacking system. The air supply is centrally supplied and accurately controlled through the independently arranged air injection fan set 508, which not only ensures the stability of the air flow required for buffer stacking, but also facilitates the adjustment of air pressure and air volume to adapt to the processing needs of different specifications of workpieces. At the same time, the external design effectively reduces the influence of vibration on the stacking accuracy.

[0075] As another embodiment of the present application, a multi-way hose is connected to the top end of the air delivery pipe 5082, and the other end of the multi-way hose is connected to the air pipe 5043.

[0076] In the present application, the main air path is flexibly connected to the plurality of movable air pipes 5043 through the multi-way hose, ensuring that the air path connection remains unobstructed at all times when the expansion and contraction block 5042 drives the air pipe 5043 to move radially for adjustment, and will not be blocked or fall off due to position changes.

[0083] The belt conveyor 3 sequentially conveys the battery base and the battery top cap to the end;

[0084] The workpiece is guided by the correction frame 4 to ensure that it enters the working area of the stacking mechanism 5 in the correct attitude.

[0085] Step three, receiving and stacking of the stacking mechanism;

[0086] First, the system controls the fan 5081 of the air injection fan set 508 to generate air flow, which is delivered to the air pipe 5043 on the expansion and contraction block 5042 through the air delivery pipe 5082 and the multi-way hose, and is blown obliquely upward from the tapered pipe 5045;

[0087] When the battery base is sent to the stacking station, the motor 5051 of the driving unit 505 drives the inner ring 5023 on the fixed disc 502 to rotate through the driving wheel 5052 and the belt 5053;

[0088] The inner ring 5023 drives the multiple gears 5041 engaged with it to rotate synchronously, and the gears 5041 drive the tooth grooves 5044 on the expansion blocks 5042, so that all the expansion blocks 5042 move radially inward along the sliding grooves 5024;

[0089] The movement of the expansion blocks 5042 is converted into a pushing force on the upright plate A 5033 and the upright plate B 5034 of the floating assembly 503 through the rocker 5064 of the rocker assembly 506, and then through the linkage of the insertion rod 5037 and the sleeve ring 5036, so that all the upright plates and the flexible inclined plates A 5031 and B 5032 above them expand synchronously. At this time, the air chamber of the floating assembly 503 expands, and according to the Venturi effect, the flow rate slows down and the buffering force decreases, so as to adapt to the battery base with larger size but lighter weight.

[0090] Step four, buffering the falling and stacking of the battery top cap;

[0091] After the battery base is in place, the battery top cap is conveyed directly above it;

[0092] The system controls the air blower 5081 of the air blower set 508 to generate airflow, which is sent to the air pipe 5043 on the expansion block 5042 through the air conveying pipe 5082 and the multi-way hose, and blows obliquely upward from the tapered pipe 5045;

[0093] At the same time, the driving unit 505 drives the floating assembly 503 to shrink synchronously. At this time, the air chamber of the floating assembly 503 shrinks, and according to the Venturi effect, the flow rate increases and the buffering force increases, so as to adapt to the battery top cap with smaller size and larger weight;

[0094] When the battery top cap starts to fall, this concentrated airflow forms an upward force below it, effectively buffering and slowing down its falling trend and speed.

[0095] Step five, soft landing and precise stacking;

[0096] Under the action of airflow buffering, the battery top cap slowly and smoothly descends at a slow speed, and finally is accurately placed on the battery base below, completing the precise stacking of a battery shell assembly. This process completely eliminates the impact damage of the top heavy object on the bottom light and thin workpiece.

[0097] Step six, discharging and recycling;

[0098] The completed stacked assembly is transferred to the unloading tray 507. When the stack reaches a predetermined number, the blocking frame 5073 of the unloading tray 507 is rotated to open the discharge port 5072, and the finished assembly is discharged; the system is reset, and the production and stacking cycle of the next set of battery bases and battery top caps begins.

[0099] The embodiments of the present application are disclosed above, but not limited to, the ordinary skilled in the art can easily understand the spirit of the present application, and make different inferences and changes, as long as they do not deviate from the spirit of the present application, which are within the protection scope of the present application.
