Description

Technical Field

[0001] The present invention relates to the field of stamping technology, in particular to a stamping product collecting device with a stacking device and a stacking method. Background Art

[0002] Stamping is widely used in the industry as a simple and efficient production method. In order to simplify the mold structure and ensure production efficiency, the mold is usually designed to be blanked under the mold. For the collection of the blanks (stamping products) after blanking, the conventional practice is to place a material frame or conveyor belt under the mold. After stamping, the blanks fall freely into the material frame or conveyor belt, and then they are manually sorted and stacked. This process requires a lot of time and energy of the operators, which is not conducive to automated production operations, and the production efficiency is also very low.

[0003] In addition, for thicker sheets, affected by the mold gap and punching force, one side of the edge of the product will show different degrees of arc edges after the first rough punching, which does not meet the quality requirements. The stamped product needs to be turned over and punched a second time to achieve the purpose of cutting off the arc edges and leveling. To facilitate the second punching, the rough punched products need to be manually identified and folded one by one in the same direction (forward or reverse of the first punching direction). This process often takes a lot of workers' time and energy and cannot meet the needs of mass production. Summary of the invention

[0004] In order to solve the above problems, one of the objectives of the present invention is to provide an automatic stamping product folding device which can automatically collect and stack stamping products in the same direction.

[0005] In order to achieve the main purpose of the present invention, the stamping product collection device provided by the present invention includes a frame, a conveying device, a stacking device and a control device; the conveying device is installed on the frame; the stacking device includes a lifting and holding device, a stacking platform and a first stopper, and the lifting and holding device is installed on the frame; the lifting and holding device is connected to the stacking platform, and the lifting and holding device can drive the stacking platform to rise and fall, and can fix the stacking platform in the position after lifting and falling; the stacking platform is arranged at one end of the conveying outlet of the conveying device, and the first stopper is arranged on the frame and stands on the side of the stacking platform away from the conveying device; the control device is electrically connected to the lifting and holding device.

[0006] As can be seen from the above, the present invention, through the arrangement and structural design of the stamping product collecting device, the stacking platform is arranged at one end of the conveying outlet of the conveying device; in the initial state, the lifting and holding device drives the stacking platform to rise to a position where the upper surface is flush with the conveying surface of the conveying device or lower than the conveying surface of the conveying device, preferably, the upper surface of the stacking platform is slightly lower than the conveying surface of the conveying device, and the stamping products can be conveyed to the stacking platform through the conveying device; after the stacking platform stacks a set number of stamping products (if the upper surface of the stacking platform is flush with the conveying surface of the conveying device in the initial state, the stacking platform needs to be lowered after stacking one stamping product), the stacking platform is driven to descend to a set height (the specific value can be set according to the material thickness of the stamping product) by the lifting and holding device, so that the conveying platform can continue to stack new stamping products. The stamped products put in can be stacked on the stacking platform after multiple cycles, which is convenient for collecting and stacking the stamped products; when a set number of stamped products are stacked on the stacking platform, the stacked stamped products are taken out of the stacking platform, and then the lifting and holding device drives the stacking platform to rise to the initial state to continue the stacking operation, and the cycle is repeated; and a first stopper is provided on the side of the stacking platform away from the conveying device, which can limit the stamped products from passing out of the stacking platform and ensure that the stamped products can be neatly stacked on the stacking platform; in particular, the stacking platform does not change the direction of the stamped products when stacking them, so that the stacked stamped products all maintain the same direction (forward or reverse of the first stamping direction), avoiding manual secondary screening and sorting, saving time and improving production efficiency.

[0007] A preferred solution is that the stacking device also includes a pressing device, which includes a pressing mechanism telescopically arranged above the stacking platform, and the pressing mechanism can be telescopically pressed to contact the stacking platform or the stamped product on the stacking platform; the pressing device is electrically connected to the control device.

[0008] As can be seen from the above, the stacking platform is arranged at one end of the conveying outlet of the conveying device, and the stamping products can be conveyed to the stacking platform via the conveying device. However, when the stamping products are conveyed to the stacking platform by the conveying device for stacking, the stamping products may not fit each other on the stacking platform and the stamping products may not fit the stacking platform, resulting in uneven stacking and even clogging of the conveying channel. Therefore, a pressing device is provided, and when a new stamping product is conveyed to the top of the stacking platform, a pressing mechanism is used to press the new stamping product conveyed to the top of the stacking platform, so that the stamping products on the stacking platform fit well with each other, and the stamping products on the stacking platform fit well with the stacking platform, so as to successfully complete the stacking of the stamping products, and also ensure that the stamping products on the stacking platform can be stacked neatly, and the stacking device can continue to perform the stacking operation smoothly.

[0009] A further solution is that the stacking device also includes an incoming material detection device, which detects whether there are stamping products transmitted to the top of the stacking platform; the incoming material detection device is electrically connected to the control device.

[0010] As can be seen from the above, since the production and transmission frequency of stamping products is not fixed, the frequency of stamping products being transmitted to the stacking device is also not fixed. Therefore, if a fixed pressing frequency is set for the pressing device, and a fixed lifting frequency is set for the lifting and holding device, the lifting and holding device and the pressing device may continue to operate even when no stamping products are transmitted, causing the stacking platform to continue to descend when no stamping products are transmitted, resulting in the stacking device running empty. In addition, in the case of excessive descending of the stacking platform, since there is a large height difference between the stacking platform and the stamping products stacked on the stacking platform and the conveying surface of the conveying device, if a new stamping product is transmitted at this time, it may cause the newly transmitted stamping product to fail to be stacked on the stacking platform as required, resulting in stacking abnormalities. Therefore, a material detection device is set to detect the transmission of stamping products, and the control device controls the action of the lifting and holding device and the pressing device according to the transmission of the stamping products to the stacking platform. This can ensure that the lifting and holding device and the pressing device can operate in an orderly manner and avoid the occurrence of stacking abnormalities.

[0011] A further solution is to further include a connecting platform, wherein the upper surface of one end of the connecting platform is connected to the conveying surface of the conveying device, and the other end of the connecting platform is connected to the stacking platform.

[0012] As can be seen from the above, a general conveying device has a curved surface at one end of the conveying outlet. The conveying of stamped products on the curved surface has great uncertainty, and the stamped products may flip over, so that the stamped products cannot be smoothly conveyed to the top of the stacking platform as required. Therefore, a connecting platform is set between the conveying device and the stacking platform, and the stamped products are conveyed from the conveying device to the connecting platform. The stamped products on the connecting platform can be pushed forward by the stamped products on the conveying equipment until the stamped product at the front end in the conveying direction is pushed against the first stop block, and the lifting and holding device drives the stacking platform to descend to a set height. The stamped product that hits the first stop block follows the stacking platform to descend under the action of gravity, or the stamped product that hits the first stop block is pressed by the pressing device to fit on the stacking platform or on the stacking platform.

[0013] A further solution is that it also includes a pause device, the upper surface of the connecting table is flush with the conveying surface of the conveying device, the pause device includes a telescopic rod located above the connecting table and facing the connecting table, the telescopic rod can be extended to touch and press the connecting table or touch and press the stamped product on the connecting table.

[0014] As can be seen from the above, since the stamping products on the connecting table need to be pressed and transmitted by the stamping products on the conveying device, the stamping products will squeeze each other during the conveying process before being transmitted to the stacking platform, so that one end of the stamping product newly transmitted to the top of the stacking platform will collide with the first stop block, and the other end will collide with the stamping product that is about to be introduced; therefore, a pressing device is provided, and when the stacking platform descends, a pressing mechanism is used to press the stamping product above the stacking platform, so that it descends synchronously with the stacking platform to complete the stacking of the stamping products above the stacking platform; however, when the pressing device presses the stamping product above the stacking platform, it may cause the stamping product that is about to be introduced to flip over, causing abnormal transmission; therefore, a pause device is provided, and before the pressing device presses the stamping product above the stacking platform, a telescopic rod is first used to press the stamping product that is about to be introduced on the connecting table, so as to avoid the stamping product that is about to be introduced from flipping over, and also to avoid the stamping product that is about to be introduced from affecting the pressing device to press the stamping product above the platform.

[0015] Another preferred solution is that the stacking device also includes a first adjusting and holding mechanism, which is connected to the first stopper, and can drive the first stopper to move toward or away from the conveying device, and can fix the first stopper in the adjusted position.

[0016] As can be seen from the above, since the sizes of stamped products in different batches may be different, if the size of the stamped product is too large, one end of the stamped product may have already hit the first stop while the other end is still on the connecting table or the conveying device, causing abnormal stacking; if the size of the stamped product is too small, the stacking may become loose; therefore, a first adjusting and holding mechanism is provided, which drives the first stop to move toward or away from the conveying device to change the limit size of the first stop, so that the distance between the first stop and the conveying device adapts to the size of the stamped product, thereby ensuring that the stacking operation proceeds normally.

[0017] In order to solve the above-mentioned problem, a second object of the present invention is to provide a stamping product stacking method which can automatically collect and stack stamping products in the same direction.

[0018] In order to achieve the main purpose of the present invention, the present invention provides a method for stacking stamped products, which adopts the aforementioned stamping product collecting device, sets the height value of the stacking platform's descent at one time; sets the first interval time for the stacking platform to move downward; initial state: the upper surface of the stacking platform is not higher than the conveying surface of the conveying device; the conveying device operates: the conveying device operates to convey the stamping products, and the stamping products fall onto the stacking platform when they are transferred to the top of the stacking platform; the stacking platform moves downward: when the time from the last downward movement of the stacking platform reaches the first interval time, the lifting and holding device drives the stacking platform to move downward by the height value.

[0019] It can be seen from the above that when the stamping machine is stamping and producing the same batch of stamped products, the stamping frequency and the production frequency of the stamped products are relatively fixed. When stacking the stamped products, the stacking platform only needs to descend to the set height value according to the set interval time (fixed frequency), so that the upper surface of the stacking platform is always kept not higher than the conveying surface of the conveying device, so that the stamped products conveyed to the upper surface of the stacking platform can fall onto the stacking platform or onto the stamped products on the stacking platform under the action of gravity, thereby completing the stacking operation of the same batch of stamped products; a lifting and holding device is provided so that the height difference between the upper surface of the stacking platform and the conveying surface of the conveying device can be controlled, and the stamped products will not flip over after falling onto the stacking platform due to the excessive height difference between the upper surface of the stacking platform and the conveying surface of the conveying device, so that the stacking device can stack the materials neatly, and ensure that the directions of the stamped products stacked by the stacking device (forward or reverse direction of stamping) are the same, thereby avoiding subsequent manual identification and screening.

[0020] In order to solve the above problems, the third object of the present invention is to provide a stamping product stacking method that can automatically collect and stack stamping products in the same direction.

[0021] In order to achieve the main purpose of the present invention, the present invention provides a method for folding stamped products, which adopts the aforementioned automatic folding device for stamped products, sets the height value of the stacking platform to be lowered once; sets the first interval time for the stacking platform to move downward; sets the second interval time for the pressing device to press the material; initial state: the upper surface of the stacking platform is not higher than the conveying surface of the conveying device; the conveying device operates: the conveying device operates to convey the stamped products, and the stamped products are transferred to the stacking platform; the pressing device presses the material: when the time from the last time the pressing device pressed the material reaches the second interval time, the pressing mechanism touches and presses the stamped product on the stacking platform once. The stacking platform moves downward: when the time from the last time the stacking platform moved downward reaches the first interval time, the lifting and holding device drives the stacking platform to move downward by the height value.

[0022] As can be seen from the above, the stacking platform is arranged at one end of the conveying outlet of the conveying device, and the stamping products can be conveyed to the stacking platform via the conveying device. However, when the stamping products are conveyed to the stacking platform by the conveying device for stacking, the stamping products may not fit each other on the stacking platform and the stamping products may not fit the stacking platform, resulting in uneven stacking and even clogging of the conveying channel. Therefore, a pressing device is provided, and when a new stamping product is conveyed to the top of the stacking platform, a pressing mechanism is used to press the new stamping product conveyed to the top of the stacking platform, so that the stamping products on the stacking platform fit well with each other, and the stamping products on the stacking platform fit well with the stacking platform, so as to successfully complete the stacking of the stamping products, and also ensure that the stamping products on the stacking platform can be stacked neatly, and the stacking device can continue to perform the stacking operation smoothly.

[0023] In order to solve the above problems, a fourth object of the present invention is to provide a stamping product stacking method that can automatically collect and stack stamping products in the same direction.

[0024] In order to achieve the main purpose of the present invention, the present invention provides a method for stacking stamped products, which adopts the aforementioned automatic stacking device for stamped products, sets the height value of the stacking platform descending once; sets the first preset interval stacking amount; sets the second preset interval stacking amount; initial state: the stacking platform is not higher than the connecting platform; the conveying device operates: the conveying device operates to convey the stamping products, and the stamping products are transmitted to the stacking platform to trigger the incoming material detection device; the pressing device presses the materials: when the incoming material detection device detects that the number of stacked materials on the stacking platform has reached the second preset interval stacking amount since the last time the pressing device pressed the materials, the pressing mechanism touches and presses the stamping products on the stacking platform once; the stacking platform moves downward: when the incoming material detection device detects that the number of stacked materials on the stacking platform has reached the first preset interval stacking amount since the last time the pressing device pressed the materials, the lifting and holding device drives the stacking platform to move downward by the height value.

[0025] As can be seen from the above, since the production and transmission frequency of stamping products is not fixed, the frequency of stamping products being transmitted to the stacking device is also not fixed. Therefore, if a fixed pressing frequency is set for the pressing device, and a fixed lifting frequency is set for the lifting and holding device, the lifting and holding device and the pressing device may continue to operate in the absence of stamping products being transmitted, causing the stacking platform to continue to descend in the absence of stamping products being transmitted, resulting in the phenomenon of the stacking device running empty. In addition, in the case of excessive descending of the stacking platform, since the stacking platform and the stamping products stacked on the stacking platform have been in contact with the conveying device of the conveying device, There is a large height difference between the surfaces. If a new stamping product is introduced at this time, it may cause the newly introduced stamping product to not be stacked on the stacking platform as required, resulting in stacking abnormality; therefore, a material detection device is set to detect the introduction of stamping products, and the control device controls the action of the lifting and holding device and the pressing device according to the situation of the stamping products being introduced into the stacking platform (the stacking platform descends once after each stacking of the first preset interval, and the pressing device presses once after each stacking of the second preset interval). This can ensure that the lifting and holding device and the pressing device can operate in an orderly manner to avoid the occurrence of stacking abnormalities.

[0026] In order to solve the above-mentioned problems, the fifth object of the present invention is to provide a stamping product stacking method which can automatically collect and stack stamping products in the same direction.

[0027] In order to achieve the main purpose of the present invention, the present invention provides a stamping product folding method, which adopts the aforementioned automatic folding device for stamping products, sets the height value of the stacking platform to be lowered once; sets the first preset time; sets the stacking amount at the first preset interval; sets the stacking amount at the second preset interval; initial state: the stacking platform is not higher than the connecting platform; the conveying device is in operation: the conveying device is in operation to convey the stamping product, and the stamping product on the connecting platform is resisted by the stamping product on the conveying device and continues to move to the stacking platform to trigger the incoming material detection device; the device is paused to press the material: when the incoming material detection device detects When a stamped product is transmitted to the stacking platform, the telescopic rod extends until it touches and presses the stamped product on the connecting platform, and retracts after continuous pressing for a first preset time; the pressing device presses the material: when the incoming material detection device detects that the number of stacked materials on the stacking platform has reached the second preset interval stacking amount since the last time the pressing device pressed the material, the pressing mechanism touches and presses the stamped product on the stacking platform once; the stacking platform moves downward: when the incoming material detection device detects that the number of stacked materials on the stacking platform has reached the first preset interval stacking amount since the last time the pressing device pressed the material, the lifting and holding device drives the stacking platform to move downward by a height value.

[0028] As can be seen from the above, since the stamped products on the connecting table need to be pressed and transmitted by the stamped products on the conveying device, the stamped products will squeeze each other during the transmission before being transmitted to the stacking platform, so that one end of the stamped product newly transmitted to the top of the stacking platform will collide with the first stopper, and the other end will collide with the stamped product that is about to be transmitted; therefore, a pressing device is set up, and when the stacking platform descends, a pressing mechanism is used to press the stamped product above the stacking platform, so that it descends synchronously with the stacking platform, and the stacking of the stamped products above the stacking platform is completed; however, when the pressing device presses the stamped product above the stacking platform, it may cause the stamped product that is about to be transmitted to The stamped products are flipped over, causing abnormal transmission. Therefore, a pause device is provided. Before the pressing device touches the stamped products above the stacking platform, a telescopic rod is first used to touch and press the stamped products on the connecting platform to be transferred in, so as to avoid the stamped products to be transferred in flipping over and also avoid the stamped products to be transferred in affecting the pressing device touching the stamped products above the material platform. In addition, when taking the stacked stamped products from the stacking platform, the pause device can be used to press the stamped products on the connecting platform to avoid the stamped products on the connecting platform from being continuously transferred to the stacking platform. There is no need to shut down the stamping machine and the conveying device, which is beneficial to improving the stamping efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Embodiment of the stamping product collecting device:

[0039] Please refer to Figures 1 to 8The stamping product collecting device of this embodiment includes a frame 1, a conveying device 2, a stacking device 3 and a control device (not shown in the figure); the conveying device 2 is installed on the frame 1; the stacking device 3 includes a first lifting and holding device, a stacking platform 301 and a first stopper 302, and the first lifting and holding device is installed on the frame 1; the first lifting and holding device is connected to the stacking platform 301, and the first lifting and holding device can drive the stacking platform 301 to rise and fall, and can fix the stacking platform 301 in the position after lifting; the stacking platform 301 is arranged at one end of the conveying outlet of the conveying device 2, and the first stopper 302 is arranged on the frame 1 and stands on the side of the stacking platform 301 away from the conveying device 2; the control device is electrically connected to the first lifting and holding device. The stacking platform 301 is arranged at one end of the conveying outlet of the conveying device 2; in the initial state, the first lifting and holding device drives the stacking platform 301 to rise to a position where the upper surface is flush with the conveying surface of the conveying device 2 or a position lower than the conveying surface of the conveying device 2, and the stamped products can be conveyed to the stacking platform 301 through the conveying device 2; after the stacking platform 301 stacks a set number of stamped products (if the upper surface of the stacking platform 301 is flush with the conveying surface of the conveying device 2 in the initial state, the stacking platform 301 needs to be lowered after stacking one stamped product), the stacking platform 301 is driven to descend to a set height by the first lifting and holding device, so that the conveying platform can continue to stack the newly introduced stamped products, and multiple stamped products can be stacked on the stacking platform 301 after multiple cycles, which is convenient for stacking the stamped products. The stacking platform 301 is used to collect and stack stamped products; a set number of stamped products are stacked on the stacking platform 301, and the stacked stamped products are taken away from the stacking platform 301. Then the first lifting and holding device drives the stacking platform 301 to rise to the initial state and continue the stacking operation, which is repeated in a cycle; and a first stopper 302 is provided on the side of the stacking platform 301 away from the conveying device 2. The first stopper 302 can limit the stamped products from being transmitted out of the stacking platform 301, and also ensure that the stamped products can be neatly stacked on the stacking platform 301; in particular, the stacking platform 301 does not change the direction of the stamped products when stacking the stamped products, so that the stacked stamped products all maintain the same direction (forward or reverse of the first stamping direction), avoiding manual secondary screening and sorting, saving time, and improving production efficiency.

[0040] Please refer to Figure 4 Furthermore, a first stopper 201 and a second stopper 202 are provided on the conveying surface of the conveying device 2 and are arranged along the conveying direction of the conveying device 2, and the first stopper 201 and the second stopper 202 are arranged at intervals; the setting of the first stopper 201 and the second stopper 202 can limit the deflection of the stamping products toward both sides of the conveying direction of the conveying device 2 during the conveying process, thereby ensuring that the stamping products are conveyed in a regular and orderly manner.

[0041] Please refer to Figure 4Preferably, the first stopper 201 is connected with a first adjusting and holding mechanism, and the first stopper 201 can be adjusted to be close to or away from the second stopper 202 by operating the first adjusting and holding mechanism, and the first adjusting and holding mechanism can fix the first stopper 201 in the adjusted position. Since the sizes of stamping products of different batches may be different, the first stopper 201 and the second stopper 202 with a fixed spacing cannot meet the limiting requirements of all stamping products. Therefore, a first adjusting and holding mechanism is provided to adjust the distance between the first stopper 201 and the second stopper 202. The spacing between the first stopper 201 and the second stopper 202 is adjusted by operating the first adjusting and holding mechanism to match the size of the stamping product, thereby ensuring that stamping products of different batches can be neatly and normally conveyed along the conveying direction of the conveying device 2, and the application range is wide.

[0042] Please refer to Figure 4 Preferably, the first stopper 201 is slidably mounted on the frame 1, a first threaded hole is provided on the first stopper 201, and the first adjustment and holding mechanism includes a first screw rod 203, the first screw rod 203 is rotatably connected to the frame 1, and the first screw rod 203 is threadedly engaged with the first threaded hole. By screwing the first screw rod 203, the first screw rod 203 rotates to drive the first stopper 201 to slide, thereby adjusting the distance between the first stopper 201 and the second stopper 202. The first adjustment and holding mechanism has a simple structure and is easy to adjust.

[0043] Please refer to Figure 4 Preferably, the first stopper 201 is provided with at least two first threaded holes distributed along the conveying direction of the conveying device 2, and the first adjustment and holding mechanism includes at least two first screws 203, each of which is rotatably connected to the frame 1, and each of the first screws 203 is threadedly matched with each of the first threaded holes in a one-to-one correspondence. At least two groups of first screws 203 are threadedly matched in a one-to-one correspondence, and the distance between the first stopper 201 and the second stopper 202 can be adjusted by rotating each of the first screws 203.

[0044] Please refer to Figure 3 Preferably, at least one first screw rod 203 is provided with a hand wheel 207. The setting of the hand wheel 207 enables the operator to rotate the first screw rod 203 by screwing the hand wheel 207, which makes the operation easier and more labor-saving.

[0045] Please refer to Figure 3 and Figure 4, further, each first screw rod 203 is connected by transmission. In this way, when one of the first screw rods 203 is screwed, the other first screw rods 203 can rotate together, avoiding the screwing of multiple first screw rods 203, and the operation is simpler and more convenient. There are many transmission connection methods between each first screw rod 203, for example, a sprocket is installed on each first screw rod 203, and each sprocket is connected by chain transmission; for another example, a toothed belt wheel 205 is installed on each first screw rod 203, and each toothed belt wheel 205 is connected by toothed belt 206; for another example, a gear is installed on each first screw rod 203, and each gear is connected by rack transmission. The transmission of the chain and the sprocket, the transmission of the toothed belt wheel 205 and the toothed belt 206, and the transmission of the gear and the rack can ensure that each first screw rod 203 has a fixed transmission ratio, which is conducive to making each first screw rod 203 transmit according to the set requirements.

[0046] Please refer to Figure 4 Preferably, the second stopper 202 is connected with a second adjusting and holding mechanism, and the second stopper 202 can be adjusted to be close to or away from the first stopper 201 by operating the second adjusting and holding mechanism. The structure and principle of the second adjusting and holding mechanism can be the same as those of the first adjusting and holding mechanism. The second adjusting and holding mechanism is provided for the second stopper 202, so that both the first stopper 201 and the second stopper 202 can be adjusted relative to the conveying device 2, so that not only the distance between the first stopper 201 and the second stopper 202 can be adjusted more conveniently, but also the positions of the first stopper 201 and the second stopper 202 on the conveying device 2 can be adjusted, so that the first stopper 201 and the second stopper 202 can better adapt to stamping products of different batches and sizes. Taking the conveyor belt 209 as an example, a first adjustment and holding mechanism and a second adjustment and holding mechanism are provided, so that the first stopper 201 and the second stopper 202 can be adjusted relative to the conveyor belt 209, which is beneficial for the first stopper 201 and the second stopper 202 to limit the stamped products to the center of the conveyor belt 209 for transmission, and is beneficial for adjusting the stamped products on the conveyor belt 209 to be aligned with the stacking device 3, so that the stamped products can be smoothly transmitted into the stacking device 3.

[0047] Please refer to Figure 4 Preferably, a slide bar 208 is fixed on the frame 1, a slide hole is provided on the first stopper 201, the slide bar 208 passes through the slide hole, and the axis direction of the slide bar 208 is perpendicular to the conveying direction of the conveying device 2 and parallel to the conveying surface of the conveying device 2. The first stopper 201 can slide along the slide bar 208, and the sliding direction of the first stopper 201 is perpendicular to the conveying direction of the conveying device 2 and parallel to the conveying surface of the conveying device 2. In this way, the first stopper 201 can be adjusted to move directly toward or away from the second stopper 202, and the distance between the first stopper 201 and the second stopper 202 can be directly adjusted, and the adjustment is faster and more efficient.

[0048] Please refer to Figure 4Furthermore, the conveying device 2 includes a conveyor belt 209 , a first pulley 210 and a second pulley. A supporting mechanism 211 is provided between the first pulley 210 and the second pulley, and the conveyor belt 209 is supported on the supporting mechanism 211 . Using a conveyor belt 209 to transport materials is a commonly used method in industrial production, and can achieve the function and purpose of transportation; in addition, since the rigidity of the conveyor belt 209 is generally low, and the stamping products are generally steel products with large density and mass, if the conveyor belt 209 is only tightened by the first pulley 210 and the second pulley, then the conveyor belt 209 may be bent due to the gravity of the stamping products when transporting the stamping products, which is not conducive to the transportation of the stamping products, nor is it conducive to the continuous normal operation of the conveyor belt 209; therefore, a supporting mechanism 211 is set between the first pulley 210 and the second pulley, and the conveyor belt 209 is supported on the supporting mechanism 211 under the action of its own gravity and / or the gravity of the stamping products, so that the upper surface of the conveyor belt 209 remains flat, ensuring the smooth transportation of the stamping products on the conveyor belt 209.

[0049] Please refer to Figure 3 Preferably, the conveying device 2 of the stamping product collection device of this embodiment further includes a third adjusting and holding mechanism 212, the first pulley 210 is rotatably arranged on the third adjusting and holding mechanism 212, the third adjusting and holding mechanism 212 can adjust the first pulley 210 to be close to or away from the second pulley, and the third adjusting and holding mechanism 212 can keep the first pulley 210 in the adjusted position. Since the installation of the conveyor belt 209 needs to be tightened on the first pulley 210 and the second pulley, in order to facilitate the installation and disassembly of the conveyor belt 209 and to facilitate the tightening of the conveyor belt 209, the third adjusting and holding mechanism 212 is provided to facilitate the adjustment of the distance between the first pulley 210 and the second pulley, and to keep the first pulley 210 in the adjusted position. When installing the conveyor belt 209, the third adjusting and holding mechanism 212 is operated to shorten the distance between the first pulley 210 and the second pulley. After the conveyor belt 209 is put on the first pulley 210 and the second pulley, the third adjusting and holding mechanism 212 is adjusted to increase the distance between the first pulley 210 and the second pulley to tighten the conveyor belt 209. In addition, the conveyor belt 209 is prone to deformation after long-term use and is prone to stretching due to long-term tension, which causes the conveyor belt 209 to become loose and slip relative to the first pulley 210 and the second pulley after a period of use. At this time, the first pulley 210 can be adjusted to move away from the second pulley by operating the third adjusting and holding mechanism 212 to re-tighten the conveyor belt 209. The function of the third adjusting and holding mechanism 212 is similar to that of the first adjusting and holding mechanism, and the third adjusting and holding mechanism can be set with reference to the first adjusting and holding mechanism.

[0050] Please refer to Figure 1 , Figure 3 and Figure 6Furthermore, the stacking device 3 of the stamping product collection device of the present embodiment also includes a pressing device, which includes a pressing mechanism 304 telescopically arranged above the stacking platform 301, and the pressing mechanism 304 can be telescopically pressed to touch the stacking platform 301 or to touch the stamping products on the stacking platform 301; the pressing device is electrically connected to the control device. The stacking platform 301 is arranged at one end of the conveying outlet of the conveying device 2, and the stamping products can be conveyed to the stacking platform 301 via the conveying device 2. However, when the conveying device 2 conveys the stamping products to the stacking platform 301 for stacking, the stamping products may not fit each other on the stacking platform 301, and the stamping products may not fit the stacking platform 301, resulting in uneven stacking and even clogging of the conveying channel, which causes the stamping products on the conveying device 2 to be unable to be continuously conveyed to the stacking platform 301 to complete the stacking. material; therefore, a pressing device is provided, and when a new stamping product is transferred to the top of the stacking platform 301, the pressing mechanism 304 is used to touch and press the new stamping product transferred to the top of the stacking platform 301, so that the stamping products on the stacking platform 301 fit well with each other, and also make the stamping products on the stacking platform 301 fit well with the stacking platform 301, so as to smoothly complete the stacking of the stamping products, and also ensure that the stamping products on the stacking platform 301 can be stacked neatly, and the stacking device 3 can continue to smoothly perform the stacking operation.

[0051] The pressing device and the later-described pause device have similar functions, so the setting of the pressing device can refer to the later-described pause device; preferably, the pressing device includes a first pressure cylinder 305 fixed on the frame 1, and the pressing mechanism 304 is fixed to the piston of the first pressure cylinder 305. By controlling the first pressure cylinder 305 to drive the pressing mechanism 304 to extend and retract, the stamping product on the stacking platform 301 can be pressed, and the first pressure cylinder 305 is easy to control and simple and convenient to use.

[0052] Please refer to Figure 3 and Figure 6Furthermore, the stacking device 3 also includes an incoming material detection device, which detects whether there are stamping products transmitted to the top of the stacking platform 301; the incoming material detection device is electrically connected to the control device. Since the production and transmission frequency of stamping products is not fixed, the frequency of stamping products being transmitted to the stacking device 3 is also not fixed. Therefore, if a fixed pressing frequency is set for the pressing device, and a fixed lifting frequency is set for the first lifting and holding device, the first lifting and holding device and the pressing device may continue to operate even when no stamping products are transmitted, causing the stacking platform 301 to continue to descend when no stamping products are transmitted, resulting in the stacking device 3 running empty. In addition, in the case of excessive decline of the stacking platform 301, since there is a large height difference between the stacking platform 301 and the stamping products stacked on the stacking platform 301 and the conveying surface of the conveying device 2, if a new stamping product is transmitted at this time, the newly transmitted stamping product may not be stacked on the stacking platform 301 as required, resulting in stacking abnormalities. Therefore, a material detection device is provided to detect the transmission of stamping products, and the control device controls the actions of the first lifting and holding device and the pressing device according to the transmission of the stamping products to the stacking platform 301. This can ensure that the first lifting and holding device and the pressing device can operate in an orderly manner and avoid the occurrence of stacking abnormalities.

[0053] Please refer to Figure 3 and Figure 6Alternatively, the incoming material detection device can directly use the sensor 309 to sense whether a stamping product is introduced into the conveying device 2. For example, a proximity switch or a touch switch is installed on the first stopper 302. When the proximity switch or the touch switch is triggered by the stamping product, it proves that a stamping product is introduced into the stacking platform 301. At this time, the pressing device can be used to touch the stamping product so that the stamping product fits well with the stacking platform 301 or fits well with the stamping product on the stacking platform 301. Preferably, the incoming material detection device includes a movable component 308 and a sensor 309. The movable component 308 is movably arranged on the first stopper 302 and extends above the stacking platform 301 or above the stamping product on the stacking platform 301. When a newly introduced stamping product is transmitted to and hits the first stopper 302, the newly introduced stamping product can trigger the movable component 308 to move through the sensing area of ​​the sensor 309. The sensor 309 is electrically connected to the control device. Before a newly-incoming stamping product is transmitted to and collides with the first stopper 302 (the upper surface of the stacking platform 301 has been lowered below the conveying surface of the conveying device 2), the movable component 308 extends above the stacking platform 301 or above the stamping product on the stacking platform 301; when a newly-incoming stamping product is transmitted to and collides with the first stopper 302, under the contact and pressure of the newly-incoming stamping product, the movable component 308 moves relative to the first stopper 302 and passes through the sensing area of ​​the sensor 309. When the sensor 309 senses the movable component 308, the control device recognizes that the newly-incoming stamping product is transmitted to the set position above the stacking platform 301. The control device controls the action of the first lifting and holding device and the pressing device according to the number and timing of the incoming stamping products, and presses the newly-incoming stamping product to be attached to the stacking platform 301 or to the stamping product attached to the stacking platform 301.

[0054] Please refer to Figure 6Optionally, the movable component 308 can be hinged on the first stopper 302 (on the frame 1) or can be slidably mounted on the first stopper 302; when the movable component 308 is hinged on the first stopper 302, the first stopper 302 can be freely suspended above the stacking platform 301 or above the stamping product on the stacking platform 301 under the action of gravity. When a new stamping product is introduced into the stacking platform 301, the newly introduced stamping product can touch the movable component 308 and press the movable component 308 to leave the stacking platform 301. When the first lifting and holding device drives the stacking platform 301 and the stamping product on the stacking platform 301 to descend, the touching of the movable component 308 is released, and the movable component 308 is under the action of gravity. It is suspended below and returned to the top of the stamping product on the stacking platform 301; preferably, the incoming material detection device also includes a limit member, which is arranged on the rotation path of the movable component 308. When the movable component 308 hits the limit member, one end of the movable component 308 extends above the stacking platform 301 or extends to above the stamping product on the stacking platform 301; the setting of the limit member enables the movable component 308 to be restricted by the limit member when returning to the top of the stacking platform 301 under the action of gravity, so that after the movable component 308 returns to the top of the stacking platform 301, it can remain relatively still above the stacking platform 301, avoiding the movable component 308 from swinging back and forth above the stacking platform 301, making it convenient for the movable component 308 to hit the next incoming stamping product.

[0055] Optionally, the movable component 308 can also be slidably mounted on the first stop block 302 (this embodiment is not shown in the figure), and a first return member is provided between the movable component 308 and the first stop block 302. When the movable frame is slidably mounted on the first stop block 302, the movable component 308 extends from the first stop block 302 in the direction of the conveying device 2, and the movable component 308 is extended to above the stacking platform 301 under the action of the first return member; when a new stamping product is introduced to the top of the stacking platform 301, the newly introduced stamping product contacts the movable component 308 to retract to the side of the stacking platform 301 where the first stop block 302 is provided. When the first lifting and holding device drives the stacking platform 301 and the stamping products on the stacking platform 301 to descend, the movable component 308 is released from being touched, and the movable component 308 is extended again to above the stacking platform 301 under the action of the first return member, waiting for the next incoming stamping product to be detected. Of course, when the movable member 308 is hinged to the first stopper 302, the first return member can also be used to assist the movable member 308 in returning to its original position, so as to prevent the movable member 308 from rocking back and forth above the stacking platform 301. Preferably, the first return member is a compression spring, one end of which contacts the movable member 308, and the other end contacts the first stopper 302.

[0056] Please refer to Figure 3Furthermore, it also includes a connecting platform 316, the upper surface of one end of the connecting platform 316 is connected to the conveying surface of the conveying device 2, and the other end of the connecting platform 316 is connected to the stacking platform 301. Generally, there will be a curved surface at one end of the conveying outlet of a conveying device 2 (for example, a conveying device 2 conveyed by a conveyor belt 209). The conveying of stamped products on the curved surface has great uncertainty, and the stamped products may flip over, so that the stamped products cannot be smoothly conveyed to the top of the stacking platform 301 as required. Therefore, a connecting platform 316 is set between the conveying device 2 and the stacking platform 301, and the stamped products are conveyed from the conveying device 2 to the connecting platform 316. The stamped products on the connecting platform 316 can be pushed forward by the stamped products on the conveying equipment until the stamped products at the front end in the conveying direction are pushed against the first stop block 302, and the first lifting and holding device then drives the stacking platform 301 to descend to a set height. The stamped product that hits the first stop block 302 follows the stacking platform 301 to descend under the action of gravity, or the stamped product that hits the first stop block 302 is pressed by the pressing device to fit on the stacking platform 301 or on the stamped product on the stacking platform 301.

[0057] Please refer to Figure 1 Preferably, a third stopper 313 and a fourth stopper 314 are provided on both sides of the connecting platform 316 along the conveying direction of the stamping products; like the first stopper 201 and the second stopper 202, the setting of the third stopper 313 and the fourth stopper 314 can limit the conveying path of the stamping products, making the conveying of the stamping products on the connecting platform 316 more regular.

[0058] Please refer to Figure 1 Preferably, the third stopper 313 and the fourth stopper 314 are also each provided with an adjustment and retaining mechanism (the function is similar to other adjustment and retaining mechanisms, and the structure can refer to other adjustment and retaining mechanisms) to adapt to stamping products of different sizes.

[0059] Please refer to Figure 3 and Figure 6, further, it also includes a pause device. The upper surface of the connecting platform 316 is flush with the conveying surface of the conveying device 2. The pause device includes a telescopic rod 318 located above the connecting platform 316 and facing the connecting platform 316. The telescopic rod 318 can be extended to touch and press onto the connecting platform 316 or onto the stamped product on the connecting platform 316. Since the stamped product on the connecting platform 316 needs to be pressed and conveyed by the stamped product on the conveying device 2, the stamped products will squeeze each other during the conveyance before being conveyed to the stacking platform 301, so that one end of the stamped product newly conveyed to the top of the stacking platform 301 will collide with the first stopper 302, and the other end will collide with the stamped product that is about to be transferred in; therefore, a pressing device is provided, and when the stacking platform 301 descends, the pressing mechanism 304 is used to press the stamped product above the stacking platform 301, so that it descends synchronously with the stacking platform 301, completing the stacking. The stamping products on the platform 301 are stacked; however, when the pressing device touches the stamping products on the stacking platform 301, it may cause the stamping products to be transferred in to flip over, causing abnormal transmission; therefore, a pause device is provided, and before the pressing device touches the stamping products on the stacking platform 301, the telescopic rod 318 is first used to touch the stamping products to be transferred in on the connecting platform 316 to avoid flipping of the stamping products to be transferred in, and also to avoid the stamping products to be transferred in affecting the pressing device touching the stamping products on the platform.

[0060] Please refer to Figure 3 and Figure 6 Preferably, the pause device includes a second pressure cylinder 319 fixed on the frame 1, and the telescopic rod 318 is fixed to the piston of the second pressure cylinder 319. By controlling the second pressure cylinder 319 to drive the telescopic rod 318 to extend and retract, the stamping product on the connecting table 316 can be pressed, and the second pressure cylinder 319 is easy to control and simple and convenient to use.

[0061] Please refer to Figure 3 and Figure 6Preferably, an anti-skid piece is fixedly provided at the end of the telescopic rod 318 facing the connecting platform 316. Since the movement of the stamping product needs to be blocked by the static friction between the telescopic rod 318 and the stamping product, the contact pressure between the telescopic rod 318 and the stamping product will be relatively large. The use of a rigid telescopic rod 318 to directly contact and press the stamping product is likely to cause damage to the surface of the stamping product; therefore, an anti-skid piece is provided at the end of the telescopic rod 318 that is facing the connecting platform 316. When the telescopic rod 318 is extended, the anti-skid piece is used to contact and press the stamping product, which is beneficial to improving the friction coefficient between the telescopic rod 318 and the stamping product, improving the maximum static friction force applied by the telescopic rod 318 to the stamping product, and facilitating the reliability of the pause device to limit the movement of the stamping product by contacting and pressing the stamping product. At the same time, it is also beneficial to reduce the contact pressure between the telescopic rod 318 and the stamping product, and reduce the damage of the telescopic rod 318 to the stamping product; in addition, the anti-skid piece is generally a flexible piece, which can avoid the rigid contact between the telescopic rod 318 and the stamping product, thereby preventing the telescopic rod 318 from damaging the stamping product.

[0062] Please refer to Figure 3 and Figure 6 Preferably, the end surface area of ​​the telescopic rod 318 facing the connecting platform 316 is larger than the cross-sectional area of ​​the section of the telescopic rod 318 that is slidably connected to the main body of the second pressure cylinder 319. Since the static friction between the telescopic rod 318 and the stamped product is needed to block the movement of the stamped product, the contact pressure between the telescopic rod 318 and the stamped product will be relatively large. Using the rigid telescopic rod 318 to directly contact and press the stamped product is likely to cause damage to the surface of the stamped product; therefore, setting the end area of ​​the telescopic rod 318 larger than the cross-sectional area of ​​the section of the telescopic rod 318 that is slidably connected to the main body of the second pressure cylinder 319 is conducive to increasing the contact surface between the telescopic rod 318 and the stamped product, reducing the pressure (pressure per unit area) between the telescopic rod 318 and the stamped product, and reducing the damage to the surface of the stamped product caused by the telescopic rod 318, and also conducive to increasing the reliability of the telescopic rod 318 to limit the movement of the stamped product by contacting and pressing the stamped product.

[0063] Please refer to Figure 3 and Figure 4Furthermore, the stamping product collecting device of the present embodiment further includes a pressing device, which includes a pressure strip 213, and the pressure strip 213 is arranged above the conveying surface of the conveying device 2 along the conveying direction of the conveying device 2. Due to the setting of the pause device, it is easy to cause the stamping products on the conveying device 2 to touch each other, and then cause some stamping products to lift up from the conveying surface of the conveying device 2, causing the state of the stamping products on the conveying device 2 to be disordered; therefore, a pressing device is arranged above the conveying surface of the conveying device 2 to compress the space above the stamping products, so as to prevent the stamping products from tilting up due to touching each other, and to prevent the stamping products from being disordered on the conveying device 2, so as to ensure that the stamping products can be attached to the conveying surface of the conveying device 2 and be normally conveyed.

[0064] Please refer to Figure 3 and Figure 4 Preferably, it also includes a fourth adjustment and holding mechanism, by operating the fourth adjustment and holding mechanism, the distance between the pressure strip 213 and the conveying surface can be adjusted, and the fourth adjustment and holding mechanism can fix the pressure strip 213 in the adjusted position. Since the thickness of different batches of stamped products may be different, if it is fixed above the conveying surface of the conveyor 2, it may cause some batches of stamped products to still be able to tilt up, and some batches of stamped products cannot pass through the space between the conveying surface and the pressure strip 213; therefore, a fourth adjustment and holding mechanism is set for the pressure strip 213, and the fourth adjustment and holding mechanism drives the pressure strip 213 to adjust the distance between the pressure strip 213 and the conveying surface to adapt to the thickness of different batches of stamped products, and ensure that different batches of stamped products can smoothly pass through the space between the conveying surface and the pressure strip 213, and will not tilt up from the conveying surface. The function of the fourth adjustment and holding mechanism is similar to that of the first adjustment and holding mechanism, and the structure can also be set with reference to the first adjustment and holding mechanism.

[0065] Preferably, the pressure strip 213 is slidably disposed on the frame 1, and a second threaded hole is disposed on the pressure strip 213. The fourth adjustment and holding mechanism includes a second screw rod (not shown in the figure), the second screw rod is threadedly engaged with the second threaded hole, and the second screw rod is rotatably connected to the frame 1. The second screw rod is rotated to drive the pressure strip 213 to slide, so as to adjust the distance between the pressure strip 213 and the conveying surface. The fourth adjustment and holding mechanism has a simple structure and is easy to adjust.

[0066] Preferably, at least two second threaded holes are provided on the pressure strip 213, and the fourth adjustment and holding mechanism includes at least two second screws, each second screw is matched with each second threaded hole in a one-to-one correspondence, and each second screw is rotatably connected to the frame 1. At least two groups of second screws are provided in a one-to-one correspondence, and the distance between the pressure strip 213 and the conveying surface can be adjusted by rotating each second screw.

[0067] Preferably, the warping device is provided with two sets of second screws and second threaded holes, and the two second screws are transmission connected. The transmission connection method between the second screws is similar to the transmission connection method of the first screw 203 in the width adjustment device, and they can learn from each other.

[0068] Please refer to Figure 3 and Figure 4 Preferably, at least two first holes are provided on the pressure strip 213, and at least two second holes are provided on the frame 1. Each first hole and each second hole correspond to a hole group, and each hole group includes at least one long hole. The length direction of each long hole is parallel. The fourth adjustment and holding mechanism includes multiple sets of bolts 214 and nuts that are matched and connected one by one. Each bolt 214 passes through the first hole and the second hole of each hole group one by one. The first hole and the second hole of the same hole group can be matched with different positions of the long hole, so as to achieve the adjustment and change of the distance between the pressure strip 213 and the conveying surface, and the structure is simple.

[0069] Please refer to Figure 4 Preferably, two pressure strips 213 are provided, and the two pressure strips 213 are respectively provided on the first stopper 201 and the second stopper 202. The pressure strip 213 is installed on the first stopper 201 and the second stopper 202 to avoid providing a separate installation structure for the pressure strip 213, so that the structure of the warping device is more concise.

[0070] Please refer to Figure 3 and Figure 5 Furthermore, a pressure wheel device is provided above the connecting platform 316, and the pressure wheel device includes a roller 311 located above the connecting platform 316, and the rotation plane of the roller 311 is parallel to the conveying direction of the conveying device 2, and the roller 311 can contact the stamping product on the connecting platform 316. Since the stamped products on the stacking table are in contact with each other, the stamped products may be warped on the connecting table 316, causing abnormal transmission of the stamped products; therefore, a pressure wheel device is arranged above the connecting table 316, and the roller 311 contacts the stamped product on the connecting table 316. When two or more stamped products are stacked and transmitted, the pressure wheel can ensure that the product located below is transmitted first, thereby playing a role in separating the sheets and ensuring the orderly transmission of each stamped product. At the same time, it can effectively prevent the stamped products on the connecting table 316 from warping up, ensuring that the stamped products are smoothly contacted and transmitted on the connecting table 316; in addition, since the rolling plane of the roller 311 is parallel to the transmission direction of the transmission device 2, the roller 311 can rotate in the direction of the friction force when it is subjected to the friction force from the stamped product, and will not generate a blocking force opposite to the transmission direction of the stamped product. Therefore, the contact between the roller 311 and the stamped product will not cause the stamped product to be stuck due to friction, which is conducive to the smooth transmission of the stamped product on the connecting table 316.

[0071] Please refer to Figure 3 and Figure 5Preferably, the pressing wheel device also includes a connecting rod 312 and a first pre-tightening device (not shown in the figure), one end of the connecting rod 312 is hinged to the frame 1, and the other end of the connecting rod 312 is rotatably connected to the roller 311; one end of the first pre-tightening device is connected to the frame 1, and the other end is connected to the connecting rod 312; under the action of the first pre-tightening device, the roller 311 is pressed onto the connecting platform 316 or onto the stamping product on the connecting platform 316. Since the thickness of stamped products in different batches is different, if the roller 311 is set at a fixed position above the connecting platform 316, then if the thickness of the stamped product is too small, the roller 311 may not be able to contact the stamped product on the connecting platform 316, causing the stamped product to tilt; if the thickness of the stamped product is too large, the existence of the roller 311 may block the transmission of the stamped product and affect the normal transmission of the stamped product on the connecting platform 316; therefore, a connecting rod 312 and a first pre-tightening device are provided, and the roller 311 is pressed onto the connecting platform 316 or onto the stamped product on the connecting platform 316 under the action of the first pre-tightening device. In this way, on the one hand, when the stamped product is transmitted to the connecting platform 316, the roller 311 can effectively press the stamped product on the connecting platform 316 to prevent the stamped product on the connecting platform 316 from tilting due to mutual contact; on the other hand, the roller 311 can press stamped products of different thicknesses to ensure that stamped products of different batches and thicknesses can be smoothly transmitted on the connecting platform 316.

[0072] Optionally, the first pre-tightening device (not shown) includes a compression spring, a tension spring or a torsion spring. The compression spring, the tension spring and the torsion spring can all achieve a pre-tightening effect on the roller 311, so that the roller 311 contacts and presses the stamped product on the connecting platform 316, which can meet the use requirements.

[0073] Preferably, the pressing wheel device includes a sliding rod and a second pre-tightening device (this mode is not shown in the figure), the sliding rod is slidably arranged on the frame 1, and the roller 311 is pressed onto the connecting platform 316 or onto the stamped product on the connecting platform 316 under the action of the second pre-tightening device. As with the setting of the connecting rod 312 and the first pre-tightening device, the setting of the sliding rod and the second pre-tightening device, on the one hand, when the stamped product is transferred to the connecting platform 316, the roller 311 can effectively press the stamped product on the connecting platform 316 to prevent the stamped product on the connecting platform 316 from tilting due to mutual contact; on the other hand, the roller 311 can press stamped products of different thicknesses to ensure that stamped products of different batches and thicknesses can be smoothly transferred on the connecting platform 316.

[0074] Please refer to Figure 1 and Figure 3Furthermore, the stacking device 3 also includes a fifth adjusting and holding mechanism 315, which is connected to the first stopper 302. The fifth adjusting and holding mechanism 315 can drive the first stopper 302 to move toward or away from the conveying device 2, and can fix the first stopper 302 in the adjusted position. Since the sizes of stamped products in different batches may be different, if the size of the stamped product is too large, one end of the stamped product may have already hit the first stopper 302, while the other end is still on the connecting platform 316 or the conveying device 2, causing abnormal stacking; if the size of the stamped product is too small, the stacking may become loose; therefore, the fifth adjusting and holding mechanism 315 is set, and the fifth adjusting and holding mechanism 315 drives the first stopper 302 to move toward or away from the conveying device 2 to change the limit size of the first stopper 302, so that the distance between the first stopper 302 and the conveying device 2 adapts to the size of the stamped product, ensuring that the stacking operation proceeds normally.

[0075] Specifically, the function of the fifth adjustment and holding mechanism 315 is similar to that of the first adjustment and holding mechanism, and the structure of the fifth adjustment and holding mechanism 315 can be set with reference to the structure of the first adjustment and holding mechanism.

[0076] Please refer to Figure 3 and Figure 6 Preferably, the stacking device 3 further includes a second stopper 306 and a third stopper 307 arranged at intervals, and the second stopper 306 and the third stopper 307 are respectively disposed on both sides of the stacking platform 301 along the conveying direction of the conveying device 2. The second stopper 306 and the third stopper 307 are arranged so that the stamping products stacked on the stacking platform 301 can be better limited by the second stopper 306 and the third stopper 307, so as to avoid abnormal movement of the stamping products on the stacking platform 301, so that the stamping products can be stacked neatly on the stacking platform, so as to ensure the normal stacking operation and improve the stacking quality.

[0077] Please refer to Figure 3 Preferably, the stacking device 3 further includes a sixth adjusting and holding mechanism 317, which is connected to the second stopper 306. The sixth adjusting and holding mechanism 317 can drive the second stopper 306 to move toward or away from the third stopper 307, and can fix the second stopper 306 at the adjusted position. Like the fifth adjusting and holding mechanism 315, the sixth adjusting and holding mechanism 317 is provided to help adjust the distance between the second stopper 306 and the third stopper 307, thereby adjusting the limit size of the second stopper 306 and the third stopper 307, so that the stacking device 3 can neatly stack stamping products of different sizes.

[0078] Please refer to Figure 3Specifically, the second stopper 306 is connected to a connecting plate 320 from a side away from the third stopper 307 , and the connecting plate 320 is connected to the sixth adjustment and holding mechanism 317 .

[0079] Please refer to Figure 3 , Optionally, the function of the first lifting and holding device is to drive the stacking platform 301 to lift and lower, and keep the stacking platform 301 in the position after lifting, and needs to be able to withstand the gravity of the stamping product. Therefore, any first lifting and holding device that can meet the above requirements can be used here, such as linear motor transmission, gear rack transmission, etc.; Preferably, the first lifting and holding device also includes a third screw 303 and a power device (not shown in the figure), and the stacking platform 301 is slidably arranged on the frame 1 and threadedly connected to the third screw 303; the third screw 303 is fixed or transmission-connected to the rotating shaft of the power device. The third screw 303 is threadedly connected to the stacking platform 301, and the power device adjusts the lifting and lowering of the stacking platform 301 by driving the third screw 303 to rotate; since the third screw 303 is threadedly connected to the stacking platform 301, the stacking platform 301 can be maintained at any position after lifting and lowering.

[0080] Optionally, the power device is a stepper motor or a servo motor, and the control device controls the stepper motor or the servo motor to operate according to set requirements.

[0081] Please refer to Figure 3 Specifically, a connecting block 310 extends from the bottom of the stacking platform 301, the connecting block 310 is slidably connected to the frame 1, and the connecting pipe is threadedly connected to the third screw 303. Since the stacking platform 301 needs to be located at one end of the conveying outlet of the conveying device 2, the position is relatively fixed, and the installation and driving difficulty is also high; therefore, the connecting block 310 is provided, and the movement of the stacking platform 301 is controlled by fixing the connecting block 310 to the stacking platform 301, which is conducive to the easy installation of the stacking platform 301.

[0082] Please refer to Figure 3 Specifically, the function of the sixth adjustment and holding mechanism 317 is similar to that of the first adjustment and holding mechanism, and the structure of the sixth adjustment and holding mechanism 317 can refer to the structure setting of the first adjustment and holding mechanism.

[0083] Please refer to Figure 1 and Figure 7Further, the stamping product collecting device also includes a collecting device 4, which is arranged on the frame 1 and located at one end of the conveying outlet of the conveying device 2. The collecting device 4 includes a collecting platform 401 and a first pushing mechanism 402. The upper surface of the collecting platform 401 is lower than the conveying surface of the conveying device 2. The second stopper 306 stands on the collecting platform 401, and the first pushing mechanism 402 drives the second stopper 306 to move. After the stamping products are transferred to the collecting platform 401 by the conveying device 2 and stacked into a stack, the first pushing mechanism 402 drives the second stopper 306 to contact and push the stacked stamping products, so that multiple stacks of stamping products in the continuous production process are neatly stacked together, and the stamping products are automatically collected; in addition, the second stopper 306 pushes the stacked stamping products away from the stacking position (stack platform 301) of the stamping products, so that the stacking position (stack platform 301) of the stamping products can continue to receive the newly introduced stamping products for stacking.

[0084] Please refer to Figure 1 and Figure 3 Preferably, after the stamping products are transmitted from the conveying device 2, they are first transmitted to the stacking platform 301 for stacking. When the stamping products on the stacking platform 301 are stacked to a set number, the first lifting and holding device drives the stacking platform 301 to rise and fall to be flush with the collecting platform 401, and then the first pushing mechanism 402 drives the second stop block 306 to push the stamping products to the collecting platform 401; after the stamping products on the stacking platform 301 are pushed to the collecting platform 401, the stacking platform 301 returns to the initial state driven by the first lifting and holding device to continue stacking.

[0085] Please refer to Figure 1 and Figure 3 Preferably, the third stopper 307 is connected to a second lifting and holding device 409, and the second lifting and holding device 409 drives the third stopper 307 to rise and fall. In the initial state, the second stopper 306 and the third stopper 307 are respectively placed on both sides of the stacking platform 301. When the stamping products on the stacking platform 301 are stacked to a set number, before the first pushing mechanism 402 drives the second stopper 306 to push the stamping products, the second lifting and holding device 409 first drives the third stopper 307 to descend below the collecting platform 401, so as to prevent the stamping products from being pushed by the second stopper 306 and colliding with the third stopper 307.

[0086] Please refer to Figure 1Preferably, the material collecting device 4 also includes a first material blocking member 403, which is arranged on the material collecting platform 401. When the first pushing mechanism 402 drives the second blocking block 306 to push the stamping product, the second blocking block 306, the stamping product and the first material blocking member 403 collide sequentially along the pushing direction of the first pushing mechanism 402. Since a stack of stamped products contains multiple vertically overlapping stamped products, the second stopper 306 may easily cause the stacked stamped products to fall forward and scatter along the pushing direction of the second stopper 306 when pushing the stacked stamped products, so that the stacks of stamped products cannot be stacked together normally; therefore, a first stopper 403 is added, and the second stopper 306 is set to sequentially contact the second stopper 306, the stamped products and the first stopper 403 along the pushing direction of the first pushing mechanism 402 when the second stopper 306 contacts and pushes the stacked stamped products, so that the first stopper 403 can block the stacked stamped products, prevent the stacked stamped products from falling forward along the pushing direction of the second stopper 306, and ensure that the stacks of stamped products can be stacked smoothly.

[0087] Please refer to Figure 1 When the first pushing mechanism 402 is provided, the sixth adjusting and holding mechanism 317 can be used to adjust the initial position of the second stop block 306; especially when the first pushing mechanism 402 is a cylinder (or a hydraulic cylinder), the pushing stroke of the first pushing mechanism 402 will be relatively fixed, and it will be inconvenient to use the first pushing mechanism 402 to adjust the initial position of the second stop block 306.

[0088] Please refer to Figure 1 Preferably, the first stopper 403 is slidably disposed on the frame 1 , and the sliding direction of the first stopper 403 is parallel to the moving direction of the second stopper 306 . There are many ways to set the first stopper 403. For example, the first stopper 403 is placed directly on the material collection platform 401, and the first stopper 403 moves under the contact pressure of the stacked stamping products. This setting method of the first stopper 403 is relatively simple. However, if the first stopper 403 is placed directly on the material collection platform 401, it may cause the first stopper 403 to tip forward along the pushing direction of the second stopper 306 during the pushing process of the second stopper 306. If the first stopper 403 tips over, it is very likely to lose the contact pressure on the stamping product, causing the stacked stamping products to tip over and scatter. Therefore, the first stopper 403 is slidably arranged on the frame 1, so that the first stopper 403 will not tip over due to the push of external force, ensuring that the first stopper 403 can continuously and effectively prevent the stacked stamping products from tipping over and scattering.

[0089] Please refer to Figure 1Preferably, the material collection device 4 also includes a second return member, which can drive the first stop member 403 to move in a direction opposite to the pushing direction of the first pushing structure. After a set number of stamping products are stacked on the material collection platform 401, the stamping products on the material collection platform 401 need to be removed. At this time, the first stop member 403 has been pushed away from the stacking position of the stamping products by the stacked stamping products. If there are newly stacked stamping products that need to be pushed away from the stacking position at this time, the first stop member 403 will not be able to effectively resist and stop the newly stacked stamping products, which may cause the newly stacked stamping products to fall and scatter; or after each stamping product on the material collection platform 401 is removed, the first stop member 403 is manually moved back to a position close to the stacking position of the stamping products, so that the first stop member 403 can continue to contact and press to prevent the newly stacked stamping products from falling and scattering. However, this manual operation method is not conducive to automated production and wastes the operator's time and energy; therefore, a second return member is set for the first stop member 403. On the one hand, after the stamped product with the first stop member 403 is taken away, the first stop member 403 can be driven by the return member to return to a position close to the stacking position of the stamped product, so that the first stop member 403 can continue to effectively stop the stamped products of different batches, so that the collection device 4 can collect materials automatically throughout the process; on the other hand, when the first stop member 403 stops the stacked stamped products, the first stop member 403 can better stop the stamped products under the drive of the second return member, ensuring that the stamped products of each stack can be stacked neatly during the pushing process of the first material return block.

[0090] Please refer to Figure 1Optionally, the second return member can be a tension spring or a compression spring, which can realize the function of returning the first material stop member 403; preferably, the collecting device 4 also includes a pneumatic cylinder 404, the cylinder body of the pneumatic cylinder 404 is fixed to the frame 1, the piston rod of the pneumatic cylinder 404 is connected to the first material stop member 403, and the extension direction of the piston rod is parallel to the moving direction of the second stop block 306. The first stopper 403 is connected to the piston rod, which can ensure that the first stopper 403 will not fall over when the second stopper 306 pushes the stacked stamped products, thereby preventing the stacked stamped products from falling over and scattering. In addition, the setting of the pneumatic cylinder 404, on the one hand, after the stamped product that contacts the first stopper 403 is taken away, the first stopper 403 can be controlled to return to the position where the first stopper 403 initially contacts the stamped product, so that the first stopper 403 can continue to effectively contact and block stamped products of different batches, so that the collection device 4 can collect materials automatically throughout the process. On the other hand, when the first stopper 403 contacts the stacked stamped products, the first stopper 403 can be adjusted by controlling the pneumatic cylinder 404. 3 and the stacked stamped products, so that the first stopper 403 can not only effectively stop the stacked stamped products and ensure that the stacked stamped products can be neatly stacked, but also not form too much resistance to the first pushing mechanism 402, thus saving energy; in addition, because the pressure of the pneumatic cylinder 404 is controllable, the timing of the first stopper 403 returning to the position where the first stopper 403 initially stops the stamped products can be adjusted and controlled according to the usage (for example, when the stamped product that is stopped by the first stopper 403 is just taken away, the first stopper 403 should be controlled to remain in the position before the stamped product is taken away, and after the second pushing mechanism 406 completes pushing and retracts, the first stopper 403 should be controlled to return to the position where it initially stops the stamped product).

[0091] Please refer to Figure 1 Preferably, the material collection device 4 further includes a second material pushing block 405 and a second material pushing mechanism 406. The second material pushing block 405 stands on the material collection platform 401. The second material pushing mechanism 406 drives the second material pushing block 405 to move, and the moving direction of the second material pushing block 306 is perpendicular to the moving direction of the second material pushing block 405. The second block 306 and the first material pushing mechanism 402 are arranged to push the stacked stamping products and arrange them in a row along a straight line to achieve the stacking of the stacked stamping products. However, stacking the stamping products in a row greatly limits the stacking amount of the stamping products, which is not in line with people's habit of stacking stamping products. Therefore, the second material pushing block 405 and the second material pushing mechanism 406 are used to push the stamping products stacked in a straight line in a direction perpendicular to the straight line, so that the stacked stamping products can be stacked and distributed in a two-dimensional array on the material collection platform 401, so that the material collection capacity of the material collection device 4 for the stacked stamping products is doubled.

[0092] Please refer to Figure 1 Preferably, the second push block 405 is a long block extending along the moving direction of the second block 306, and the second push block 405 can be extended and retracted along the length direction. The second push block 405 is set as a long block extending along the moving direction of the second block 306, so that the second push block 405 can push multiple stacks of stamped products distributed in a row at a time; the second push block 405 is set to be retractable along the length direction, so that when the stacking length of the multiple stacks of stamped products distributed in a row changes, it can be adapted by the extension and retraction of the second push block 405, so as to avoid the second push block 405 only pushing a part of a stack of stamped products, causing the stack of stamped products to rotate and scatter.

[0093] Please refer to Figure 1 Preferably, the material collecting device 4 further comprises a second material stopper 407, which is placed on the material collecting platform 401. When the second material pushing mechanism 406 drives the second material pushing stopper 405 to push the stamped product, the second material pushing stopper 405, the stamped product and the second material stopper 407 are sequentially colliding along the pushing direction of the second material pushing mechanism 406. Like the first material stopper 403, the second material stopper 407 can prevent the stacked stamped products from scattering forward along the moving direction of the second material pushing stopper 405, which is conducive to keeping the stacked stamped products neat.

[0094] Please refer to Figure 1 and Figure 2 Specifically, the second pushing mechanism 406 is provided with a mounting plate 411 extending along the length direction of the second pushing stopper 405, and the second pushing stopper 405 includes a fixed stopper 412 and an adjusting stopper 413. The fixed stopper 412 is fixed to the middle part of the mounting plate 411 along the direction of the second pushing stopper 405, and the adjusting stopper 413 is arranged at the end of the mounting plate 411 along the direction of the second pushing stopper 405 (preferably, the adjusting stopper 413 is arranged at both ends), and the adjusting stopper 413 can be fixed at different positions of the mounting plate 411 along the length direction of the second pushing stopper 405; preferably, the second pushing mechanism 406 The stopper 405 is installed on the side of the mounting plate 411 away from the second stopper 407, and the fixed block is suspended above the stacking platform 401. The second pushing stopper 405 extends from the mounting plate 411 toward the stacking platform 401, so that the mounting plate 411 protrudes toward the second stopper 407 side compared with the second pushing stopper 405. When the second pushing stopper 405 pushes the stamping product, the second pushing stopper 405 contacts the stamping product. The portion of the mounting plate 411 that protrudes toward the second stopper 407 compared with the second pushing stopper 405 is located above the stamping product, which can more effectively ensure the neatness of the stamping product.

[0095] Please refer to Figure 1 ,and Figure 2Preferably, similar to the above-mentioned adjustment and retaining mechanisms, a plurality of mounting holes distributed along the length direction of the second push stopper 405 are provided on the mounting plate 411, and the adjustment stopper 413 is fixed to the mounting holes on the mounting plate 411 by means of pins or screws. The position of the adjustment stopper 413 is different when the adjustment stopper 413 cooperates with different mounting holes.

[0096] Please refer to Figure 1 Preferably, it further comprises a collecting hopper 408, which is detachably mounted on the frame 1, and is located on the moving path of the second pushing block 405, and the collecting plane of the collecting hopper 408 is flush with the upper surface of the collecting platform 401. The second pushing block 405 pushes the stacks of stamping products arranged in rows to the collecting hopper 408, so that the stacks of stamping products are distributed in a two-dimensional array in the collecting hopper 408. When the collecting hopper 408 accumulates a set number of stamping products, the collecting hopper 408 with the stamping products is disassembled and removed, and replaced with an empty collecting hopper 408 installed on the collecting platform 401, completing the two-dimensional array accumulation and collection of the stamping products.

[0097] Please refer to Fig. 9 Preferably, the frame 1 includes a fixed frame 102 and an adjusting frame 103, the fixed frame 102 and the adjusting frame 103 are connected by a plurality of leveling bolts 104, the collecting device 4 and the stacking device 3 are both installed on the adjusting frame 103, and the stacking platform 301 and the collecting platform 401 can be leveled by adjusting each leveling bolt 104.

[0098] It should be noted that in this embodiment, adjustment and holding mechanisms are used in many places (the first adjustment and holding mechanism, the second adjustment and holding mechanism, the third adjustment and holding mechanism 212, the fourth adjustment and holding mechanism, the fifth adjustment and holding mechanism 315, the sixth adjustment and holding mechanism 317, and the adjustment and holding mechanisms of the third stopper 313 and the fourth stopper 314). The functions of these adjustment and holding mechanisms are similar, and therefore the structures of these adjustment and holding mechanisms can be set with reference to each other. The reason why the specific structures selected for each adjustment and holding mechanism in the accompanying drawings of this embodiment are different is that on the one hand, the adjustment and holding mechanisms shown in the drawings can all realize the functions of adjustment and holding, and on the other hand, factors such as the installation conditions during specific use and the demand for adjustment frequency are taken into consideration, and it does not hinder the interchangeability of various adjustment and holding mechanisms.

[0099] Punching machine embodiment:

[0100] The punching machine of this embodiment includes a punching table 101 and the aforementioned punching product collecting device, and the end of the conveying device 2 away from the stacking device 3 is placed under the punching table 101. The punching products produced by the punching machine fall from the punching table 101 to the conveying device 2, and the conveying device 2 conveys the punching products to the stacking device 3 for stacking. The punching products are kept in the same direction as the punching direction from production to stacking in the stacking device 3. Therefore, the punching machine of the present invention can automatically realize the same-direction stacking of the punching products (forward or reverse of the punching direction), avoiding manual secondary screening and sorting, saving time, and improving production efficiency.

[0101] Embodiment 1 of the stamping product folding method:

[0102] The stamping product stacking method of this embodiment adopts the aforementioned stamping product collecting device, sets the height value of the stacking platform 301 for one descent; sets the first interval time for the stacking platform 301 to move downward; initial state: the upper surface of the stacking platform 301 is not higher than the conveying surface of the conveying device 2; the conveying device 2 is in operation: the conveying device 2 is in operation to convey the stamping products, and the stamping products fall onto the stacking platform 301 when they are transferred to the top of the stacking platform 301; the stacking platform 301 moves downward: when the time from the last downward movement of the stacking platform 301 reaches the first interval time, the first lifting and holding device drives the stacking platform 301 to move downward by the height value. When the stamping machine is stamping and producing the same batch of stamped products, the stamping frequency and the production frequency of the stamped products are relatively fixed. When stacking the stamped products, the stacking platform 301 only needs to descend to the set height value according to the set interval time (fixed frequency), so that the upper surface of the stacking platform 301 is always kept not higher than the conveying surface of the conveying device 2, so that the stamped products conveyed to the upper surface of the stacking platform 301 can fall onto the stacking platform 301 or onto the stamped products on the stacking platform 301 under the action of gravity, thereby completing the stacking operation of the same batch of stamped products; a first lifting and holding device is provided so that the height difference between the upper surface of the stacking platform 301 and the conveying surface of the conveying device 2 can be controlled, and the stamped products will not flip over after falling onto the stacking platform 301 due to the excessive height difference between the upper surface of the stacking platform 301 and the conveying surface of the conveying device 2, so that the stacking device 3 can stack the materials neatly, and ensure that the directions of the stamped products stacked by the stacking device 3 (forward or reverse direction of stamping) are the same, thereby avoiding subsequent manual identification and screening.

[0103] Embodiment 2 of the stamping product folding method:

[0104] The stamping product stacking method of this embodiment adopts the aforementioned automatic stamping product stacking device, sets the height value of the stacking platform 301 to be lowered once; sets the first interval time for the stacking platform 301 to move downward; sets the second interval time for the pressing device to press materials; initial state: the upper surface of the stacking platform 301 is not higher than the conveying surface of the conveying device 2; the conveying device 2 operates: the conveying device 2 operates to convey the stamping products, and the stamping products are transferred to the stacking platform 301; the pressing device presses materials: when the time from the last time the pressing device pressed materials reaches the second interval time, the pressing mechanism 304 touches and presses the stamping products on the stacking platform 301 once. The stacking platform 301 moves downward: when the time from the last time the stacking platform 301 moved downward reaches the first interval time, the first lifting and holding device drives the stacking platform 301 to move downward by the height value. The stacking platform 301 is arranged at one end of the conveying outlet of the conveying device 2. The stamped products can be conveyed to the stacking platform 301 via the conveying device 2. However, when the conveying device 2 conveys the stamped products to the stacking platform 301 for stacking, the stamped products may not fit together on the stacking platform 301 or the stamped products may not fit together with the stacking platform 301. The uneven stacking may even cause the conveying channel to be blocked, resulting in the stamped products on the conveying device 2 not being able to be continuously conveyed to the stacking platform 301 to complete the stacking. material; therefore, a pressing device is provided, and when a new stamping product is transferred to the top of the stacking platform 301, the pressing mechanism 304 is used to touch and press the new stamping product transferred to the top of the stacking platform 301, so that the stamping products on the stacking platform 301 fit well with each other, and also make the stamping products on the stacking platform 301 fit well with the stacking platform 301, so as to smoothly complete the stacking of the stamping products, and also ensure that the stamping products on the stacking platform 301 can be stacked neatly, and the stacking device 3 can continue to smoothly perform the stacking operation.

[0105] Embodiment 3 of the method for folding stamped products:

[0106] The stamping product stacking method of this embodiment adopts the aforementioned automatic stacking device for stamping products, sets the height value of the stacking platform 301 to be lowered once; sets the first preset interval stacking amount; sets the second preset interval stacking amount; initial state: the stacking platform 301 is not higher than the connecting platform 316; the conveying device 2 operates: the conveying device 2 operates to convey the stamping products, and the stamping products are transmitted to the stacking platform 301 to trigger the incoming material detection device; the pressing device presses the materials: when the incoming material detection device detects that the number of stacked materials on the stacking platform 301 has reached the second preset interval stacking amount since the last time the pressing device pressed the materials, the pressing mechanism 304 touches and presses the stamping products on the stacking platform 301 once; the stacking platform 301 moves downward: when the incoming material detection device detects that the number of stacked materials on the stacking platform 301 has reached the first preset interval stacking amount since the last time the pressing device pressed the materials, the first lifting and holding device drives the stacking platform 301 to move downward by the height value. Since the production and transmission frequency of stamping products is not fixed, the frequency of stamping products being transmitted to the stacking device 3 is also not fixed. Therefore, if a fixed pressing frequency is set for the pressing device and a fixed lifting frequency is set for the first lifting and holding device, the first lifting and holding device and the pressing device may continue to operate even when no stamping products are transmitted, causing the stacking platform 301 to continue to descend when no stamping products are transmitted, resulting in the stacking device 3 running empty. In addition, in the case where the stacking platform 301 is excessively descended, since the stacking platform 301 and the stamping products stacked on the stacking platform 301 have already contacted the transmission frequency of the conveying device 2, the stacking platform 301 and the stamping products stacked on the stacking platform 301 may not be able to pass through the stacking platform 301. There is a large height difference between the feeding surfaces. If a new stamping product is introduced at this time, it may cause the newly introduced stamping product to not be stacked on the stacking platform 301 as required, resulting in stacking abnormality; therefore, a material detection device is set to detect the introduction of stamping products, and the control device controls the action of the first lifting and holding device and the pressing device according to the situation of the stamping product being introduced into the stacking platform 301 (the stacking platform 301 descends once after each stacking of the first preset interval, and the pressing device presses once after each stacking of the second preset interval). This can ensure that the first lifting and holding device and the pressing device can operate in an orderly manner to avoid the occurrence of stacking abnormalities.

[0107] Preferably, each time a new stamping product is introduced into the stacking platform 301, the pressing device performs a pressing operation, and the first lifting and holding device also drives the stacking platform to drop by the thickness of one stamping product. This ensures that the stamping products are well fitted with each other, that the stamping products are well fitted with the stacking platform, and that the stamping products are neatly stacked on the stacking platform.

[0108] Specifically, set the height value of the stacking platform descending once; set the first preset interval stacking amount; set the second preset interval stacking amount; set the first interval stacking amount of the stacking platform moving downward; set the second interval stacking amount of the pressing device pressing the material;

[0109] Initial state: the stacking platform is not higher than the connecting platform, the stacking volume of the first interval is set to zero, and the stacking volume of the second interval is set to zero;

[0110] Conveying device operation: The conveying device operates to convey stamping products. The stamping products are conveyed to the stacking platform to trigger the incoming material detection device. The stacking amount of the first interval increases by one, and the stacking amount of the second interval increases by one.

[0111] The pressing device presses the material: compares the second interval stacking amount with the second preset interval stacking amount; when the second interval stacking amount is equal to the second preset interval stacking amount, the pressing mechanism touches and presses the stamped product on the stacking platform once; after the pressing mechanism touches and presses the stamped product on the stacking platform once, the second interval stacking amount is reset to zero.

[0112] The stacking platform moves down: compare the first interval stacking amount with the first preset interval stacking amount; when the first interval stacking amount is equal to the first preset interval stacking amount, the lifting and holding device drives the stacking platform to move down by a certain height; after the stacking platform moves down once, the first interval stacking amount is reset to zero.

[0113] Example 4 of the stamping product folding method:

[0114] The stamping product stacking method of this embodiment adopts the aforementioned automatic stamping product stacking device, sets the height value of the stacking platform 301 falling once; sets the first preset time; sets the stacking amount of the first preset interval; sets the stacking amount of the second preset interval; initial state: the stacking platform 301 is not higher than the connecting platform 316; the conveying device 2 operates: the conveying device 2 operates to convey the stamping products, and the stamping products on the connecting platform 316 are resisted by the stamping products on the conveying device 2 and continue to move to the stacking platform 301 to trigger the incoming material detection device; the device presses the material: when the incoming material detection device detects that there are stamping products conveyed to the stacking platform 301, the material detection device stops pressing the material. When the material pressing device is in operation, the telescopic rod 318 is extended to touch and press the stamped product on the connecting platform 316, and retracts after continuously touching and pressing for a first preset time; the pressing device presses the material: when the incoming material detection device detects that the number of stacked materials on the stacking platform 301 has reached the second preset interval stacking amount since the last time the pressing device pressed the material, the pressing mechanism 304 touches and presses the stamped product on the stacking platform 301 once; the stacking platform 301 moves downward: when the incoming material detection device detects that the number of stacked materials on the stacking platform 301 has reached the first preset interval stacking amount since the last time the stacking platform 301 was stacked, the first lifting and holding device drives the stacking platform 301 to move downward by a height value. Since the stamped products on the connecting platform 316 need to be pressed and conveyed by the stamped products on the conveying device 2, the stamped products will squeeze each other during the conveyance before being conveyed to the stacking platform 301, so that one end of the stamped product newly conveyed to the top of the stacking platform 301 will collide with the first stopper 302, and the other end will collide with the stamped product that is about to be transferred in; therefore, a pressing device is provided, and when the stacking platform 301 descends, a pressing mechanism 304 is used to press the stamped product above the stacking platform 301, so that it descends synchronously with the stacking platform 301, and the stacking of the stamped products above the stacking platform 301 is completed; however, when the pressing device presses the stamped product above the stacking platform 301, it may cause the stamped product that is about to be transferred in to collide with the first stopper 302. The incoming stamping products flip over, causing abnormal transmission; therefore, a pause device is provided, and before the pressing device touches the stamping products above the stacking platform 301, the telescopic rod 318 is first used to touch the incoming stamping products on the connecting platform 316 to avoid the incoming stamping products from flipping over, and also to avoid the incoming stamping products affecting the pressing device touching the stamping products above the material platform; in addition, when taking the stacked stamping products from the stacking platform 301, the pause device can press the stamping products on the connecting platform 316 to avoid the stamping products on the connecting platform 316 from being continuously transmitted to the stacking platform 301; there is no need to shut down the stamping machine and the conveying device 2, which is beneficial to improving the stamping efficiency.

[0115] Preferably, each time a new stamping product is introduced into the stacking platform 301, the pause device touches and presses the stamping product on the connecting platform 316 once, and then the pressing device performs a pressing operation, and the first lifting and holding device drives the stacking platform to drop by the thickness of a stamping product. This ensures that the stamping products are well fitted with each other, that the stamping products are well fitted with the stacking platform, and that the stamping products are neatly stacked on the stacking platform.

[0116] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
