Description

Technical Field

[0001] This invention relates to the field of substrate stamping inspection and control, and particularly to a substrate anti-misfeeding detection device, a substrate continuous feeding stamping system, and a method. Background Technology

[0002] In continuous stamping dies, the stamped portion often fails to meet requirements due to misfeeding of the substrate (misfeeding mainly refers to a mismatch between the feeding speed and the continuous stamping frequency; for example, a slow feeding speed with a fast continuous stamping frequency results in an overly dense stamped portion, or a fast feeding speed with a slow continuous stamping frequency results in an overly sparse stamped portion). For instance, if the substrate is not fed in time, the stamped portion stops, and the press cannot detect the feeding abnormality immediately. The continuous stamping die continues to close at the normal stamping frequency, making both the die and the product susceptible to damage. When the substrate is incorrectly positioned at the stamping die, parts that should not be stamped are damaged. Therefore, preventing misfeeding of the substrate and improving the precision of stamped products are urgent technical problems that need to be solved. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a substrate misfeeding detection device, a substrate continuous feeding stamping system and method that can improve the accuracy of substrate placement and improve the precision of stamped products.

[0004] To solve the above-mentioned technical problems, one technical solution adopted by the present invention is: to provide a substrate anti-misfeed detection device for detecting substrates conveyed to a continuous stamping station; the substrate is provided with a plurality of equally spaced detection ports on one side along the conveying direction;

[0005] The substrate misfeeding detection device includes a mounting base disposed on one side, a detection block slidably disposed on the mounting base in a direction perpendicular to the conveying direction, and a detection unit; the end of the detection block near the substrate has a detection head adapted to the shape of the detection port; the detection unit is used to send a first signal to the stamping equipment when the detection block is located in the detection port so that the stamping equipment presses the substrate downward, and is also used to send a second signal to the stamping equipment when the detection block moves out of the detection port so that the stamping unit of the stamping equipment is in a non-stamping state.

[0006] Furthermore, the side of the detection port away from the continuous stamping station along the conveying direction is defined as a guide slope that is inclined outward and away from the continuous stamping station; the detection block moves towards the substrate under the elastic force of an elastic element so that the detection head enters the detection port; the detection block moves out of the detection port by the squeezing force of the guide slope when the substrate is conveyed forward; the detection unit is disposed on the mounting base and located outside the end of the detection block away from the substrate, and is used to detect the distance P between itself and the detection block; when the detection block is located inside the detection port, the distance P is equal to the preset safety distance P1, and a first signal is sent to the stamping equipment to make the stamping unit of the stamping equipment press the substrate downward; when the detection block moves out of the detection port, the distance P is less than the safety distance P1, and a second signal is sent to the stamping equipment to make the stamping unit of the stamping equipment in a non-stamping state.

[0007] Furthermore, the detection unit is defined as any one of the following: a laser detection unit, an ultrasonic detection unit, an infrared detection unit, a limit switch, and a proximity switch, which is a distance detection unit capable of detecting the distance between two objects.

[0008] Furthermore, it also includes a limiting block disposed on the mounting base. The limiting block has a through groove extending in a direction perpendicular to the conveying direction and with its opening facing the mounting base. The through groove and the side of the mounting base directly opposite it form a slide rail for the detection block to slide. The limiting block also has a through hole disposed parallel to the through groove. The detection block includes a restricted portion disposed on the side of the limiting block away from the substrate, a detection portion disposed on the side of the limiting block close to the substrate, and a sliding portion connected between the restricted portion and the detection portion and movably passing through the slide rail. The detection head is formed at the end of the detection portion facing the substrate. A clearance groove is formed on the side of the sliding portion facing the through hole, and on the two sides of the detection portion and the restricted portion directly opposite each other. The length of the clearance groove in a direction perpendicular to the conveying direction is greater than the length of the limiting block in the corresponding direction. The end of the elastic member away from the substrate is disposed in the through hole, and the end close to the substrate is connected to the detection portion.

[0009] To solve the above-mentioned technical problems, another technical solution adopted by the present invention is: to provide a substrate misfeeding detection method, used to detect misfeeding of the substrate during the substrate feeding process, comprising the following steps:

[0010] Several equally spaced detection ports are set on one side of the substrate along the conveying direction;

[0011] A detection block that can move in a direction perpendicular to the conveying direction is provided on one side of the substrate where the detection port is provided;

[0012] A detection unit is used to detect whether the detection block is located within the detection port;

[0013] When the detection unit detects that the detection block is located in the detection port, it considers the substrate to have been moved into place and sends a first signal to the stamping equipment so that the stamping equipment presses the substrate downward.

[0014] When the detection unit detects that the detection block has moved out of the detection port, it considers that the substrate has not been moved into place and sends a second signal to the stamping equipment to keep the stamping equipment in a non-stamping state.

[0015] Furthermore, the detection unit is disposed at the end of the detection block away from the substrate. The step of having the detection unit detect whether the detection block is located within the detection port includes the following sub-steps:

[0016] The distance between the detection block and the detection unit when the detection block is located inside the detection port is set as a safe distance P1;

[0017] Detect the distance P between the detection unit and the detection block;

[0018] When the detection block is located within the detection port, the distance P is equal to the preset safety distance P1: a first signal is sent to the stamping equipment to cause the stamping unit of the stamping equipment to press the substrate downward; a first signal is sent to the detection port stamping mechanism to cause the detection port stamping mechanism and the stamping equipment to press the substrate downward simultaneously.

[0019] When the detection block moves out of the detection port, the distance P is less than the safety distance P1: a second signal is sent to the stamping equipment to keep the stamping equipment in a non-stamping state; a second signal is sent to the detection port stamping mechanism to make the detection port stamping mechanism and the stamping equipment simultaneously in a non-stamping state.

[0020] To solve the above-mentioned technical problems, another technical solution adopted by the present invention is: a continuous feeding and stamping system for substrates, including a stamping device and a feeder for continuously feeding substrates to the stamping device, and further including the substrate anti-misfeeding detection device disposed in the substrate conveying route; the stamping device is used to stamp the substrate downward according to a first signal sent by the substrate anti-misfeeding detection device, and is also used to make the stamping unit in a non-stamping state with the stamping unit raised upward according to a second signal sent by the substrate anti-misfeeding detection device, and to send a third signal to the feeder when the stamping unit moves upward; the feeder is used to pause feeding after receiving the first signal, and is also used to continue feeding after receiving the third signal.

[0021] Furthermore, the distance between every two adjacent detection ports on the substrate is adapted to the step distance of the feeder;

[0022] The continuous substrate feeding and stamping system further includes a detection port stamping mechanism disposed between the substrate misfeed detection device and the feeder, the detection port stamping mechanism operating synchronously with the stamping unit of the stamping equipment; and / or

[0023] The continuous feeding and stamping system for the substrate also includes an edge trimming machine disposed between the substrate anti-misfeeding detection device and the stamping equipment for trimming the two lateral sides of the substrate. The edge trimming machine operates synchronously with the stamping unit of the stamping equipment.

[0024] To solve the above-mentioned technical problems, another technical solution adopted by the present invention is: to provide a continuous feeding and stamping method for a substrate, comprising the following steps:

[0025] The feeder continuously supplies the substrate to the stamping equipment;

[0026] A plurality of equally spaced detection ports are provided on one side of the substrate along the conveying direction; wherein, the side of the detection port away from the continuous stamping station along the conveying direction is defined as a guide slope that is away from the continuous stamping station and inclined outward.

[0027] The detection block located on one side of the substrate where the detection port is provided is brought into the detection port under the elastic force of an elastic element;

[0028] A detection unit is used to detect whether the detection block is located within the detection port;

[0029] When the detection unit detects that the detection block is located in the detection port, it is considered that the substrate has been moved into place, and a first signal is sent to both the stamping equipment and the feeder.

[0030] The feeder is paused, and the stamping unit of the stamping equipment is pressed downwards to press the substrate.

[0031] When the stamping unit of the stamping equipment moves upward, it sends a third signal to the feeder; after receiving the third signal, the feeder continues to feed, causing the detection head to move out of the detection port under the action of the guide slope;

[0032] When the detection unit detects that the detection block has moved out of the detection port, it considers that the substrate has not been moved into place and sends a second signal to the stamping equipment.

[0033] The stamping equipment is kept in a non-stamping state after moving upward according to the second signal.

[0034] Furthermore, in the step of setting a plurality of equally spaced detection ports on one side of the substrate along the conveying direction, the detection ports are formed by pressing the substrate downward by a detection port punching mechanism set between the feeder and the detection block.

[0035] When the detection unit detects that the detection block is located inside the detection port, the detection unit simultaneously sends a first signal to the detection port stamping mechanism, the stamping equipment, and the feeder.

[0036] The feeder is paused, and both the detection port stamping mechanism and the stamping unit of the stamping equipment are pressed downwards onto the substrate.

[0037] When the detection unit detects that the detection block has moved out of the detection port, the detection unit simultaneously sends a second signal to both the stamping equipment and the stamping mechanism of the detection port.

[0038] The stamping unit and the stamping mechanism of the inspection port of the stamping equipment are kept in a non-stamping state after moving upward.

[0039] The substrate misfeeding detection device, substrate continuous feeding stamping system and method of the present invention have the following beneficial effects: by setting detection ports at equal intervals on the long side of the substrate, and designing the distance between each two adjacent detection ports to match the step size of the feeder, the substrate is used as the basis for detecting whether it is fed into place. Whether the detection block located outside the long side of the substrate enters the detection port is used as the judgment of whether the substrate is fed into place. The first signal issued by the detection unit when the detection block enters the detection port is used as the trigger for whether the stamping equipment should perform stamping. When the detection block enters the detection port, the detection unit sends a first signal to both the stamping equipment and the feeder. Upon receiving the first signal, the feeder pauses feeding. Upon receiving the first signal, the stamping equipment causes the stamping unit to press the substrate downwards. When the stamping unit moves upwards, it sends a third signal to the feeder, which then continues feeding. The substrate moves the detection port toward the stamping equipment. As the guide bevel of the detection port moves toward the stamping equipment, it presses the detection head outwards, causing the detection block to move outwards (towards the detection unit) and compress the elastic element. As the detection block moves outwards, the distance P between the detection block and the detection unit gradually decreases, becoming less than the safety distance P1. This serves as a trigger signal to lift the stamping unit upwards and keep it stationary in a non-stamping state. This ensures that the stamping unit remains stationary while the substrate moves, preventing accidental stamping, damage to the product, or equipment. In summary, the substrate misfeeding prevention device of the present invention can realize the detection of substrate misfeeding through the cleverly designed detection port, detection block, elastic element and detection unit. The movement of each component is realized by its own force, without the need for external driving force equipment, so as to achieve precise control of substrate feeding position and improve product yield.

[0049] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0052] Please see Figures 1 to 3 In this embodiment, the substrate misfeed detection device 100 is used to perform misfeed detection on the substrate 200 being conveyed to the continuous stamping station. The substrate 200 can be limited to any material that requires continuous stamping, such as a metal bipolar plate. An air-cooled bipolar plate is one type of metal bipolar plate, mainly used in drones, portable power supplies, and other fields. Air-cooled metal bipolar plates are typically manufactured by stamping from a 0.05-0.10mm thick titanium or stainless steel substrate 200. One component of the air-cooled metal bipolar plate is the cathode plate, and the flow channel shape is usually a parallel direct current channel, formed using a high-speed continuous die forming process.

[0053] The substrate 200 is conveyed to a stamping device (not shown) via a feeder. The direction of the substrate 200 from the feeder to the stamping device is defined as the conveying direction of the substrate 200. The side of the substrate 200 parallel to the conveying direction is defined as the side in the length direction (long side), that is, the length direction of the substrate 200 is in the same direction as the conveying direction. The side of the substrate 200 perpendicular to the conveying direction is defined as the side in the width direction (short side), that is, the width direction of the substrate 200 is perpendicular to the conveying direction. A plurality of equally spaced detection ports 102 are provided on one side 101 (long side) of the substrate 200 along the conveying direction. The distance between each pair of adjacent detection ports 102 is adapted to the step distance of the feeder. The side of each detection port 102 away from the continuous stamping station along the conveying direction is defined as a guide slope 102a that is inclined outward and away from the continuous stamping station. In a specific example, each detection port 102 extends outward through the substrate 200 in a direction perpendicular to the conveying direction (hereinafter referred to as the width direction). The side of the detection port 102 closest to the stamping equipment along the conveying direction can be defined as a first flat surface 102b perpendicular to the conveying direction. The bottom of the detection port 102 parallel to the long side is defined as a second flat surface 102c parallel to the long side. The guide slope 102a is formed by tilting outward from the second flat surface 102c toward the feeder and along the width direction of the substrate 200.

[0054] The substrate misfeeding detection device 100 is disposed on the long side of the substrate 200 where the detection port 102 is provided, and includes a mounting base 210 disposed on the side 101, a detection block 220 slidably disposed on the mounting base 210 in a direction perpendicular to the conveying direction, and a detection unit 230.

[0055] The mounting base 210 has a horizontal mounting platform. A groove 211 is provided on the mounting platform along the width direction of the substrate 200, and the groove 211 extends through the mounting platform along the width direction of the substrate 200. A limiting block 240 is also provided on the mounting platform. The limiting block 240 has a through hole 241 extending along the width direction of the substrate 200, and a through groove 242 parallel to the through hole 241. The through groove 242 extends along the width direction of the substrate 200 with its opening facing the mounting base 210 (downward). The through groove 242 and the side of the mounting base 210 directly opposite it form a slide for the detection block 220 to slide. That is, the groove 211 and the through groove 242 together form the slide.

[0056] The detection block 220 is slidably disposed in the groove 211 along the width direction of the substrate 200 and is limited by the slide rail in the vertical direction. The detection block 220 includes a limiting part 221 disposed on the side of the limiting block 240 away from the substrate 200, a detection part 222 disposed on the side of the limiting block 240 close to the substrate 200, and a sliding part 223 connecting the limiting part 221 and the detection part 222 and movably passing through the slide rail. The limiting part 221 cooperates with the limiting block 240 to limit the movement of the detection block 220 toward the substrate 200. When the limiting part 221 abuts against the side of the limiting block 240 away from the substrate 200, the detection part 222 just enters the detection port 102 without exerting a force on the second flat surface 102c of the detection port 102 (for example, the detection part 222 approaches or is infinitely close to the second flat surface 102c). A clearance groove is formed on one side of the sliding part 223 facing the through hole 241, and on the two sides of the detection part 222 and the limiting part 221 facing each other. The length of the clearance groove along the width direction of the substrate 200 is greater than the length of the limiting block 240 in the corresponding direction. An elastic element 224 is provided at the end of the detection block 220 away from the substrate 200. The elastic element 224 can be defined as a helical spring. The end of the helical spring away from the substrate 200 is disposed in the through hole 241 or abuts against the limiting block 240, and the end near the substrate 200 is connected to the detection part 222. A detection head adapted to the shape of the detection port 102 is formed at the end of the detection block 220 near the substrate 200. The shape of the detection head is adapted to the detection port 102. The detection block 220 moves toward the substrate 200 under the elastic force of the elastic member 224 so that the detection head enters the detection port 102. When the substrate 200 is conveyed forward, the detection block 220 moves out of the detection port 102 by the squeezing force of the guide inclined surface 102a.

[0057] The detection unit 230 is used to send a first signal to the stamping device when the detection block 220 is located within the detection port 102, causing the stamping device to press the substrate 200 downwards. It is also used to send a second signal to the stamping device when the detection block 220 moves out of the detection port 102, causing the stamping unit of the stamping device to be in a non-stamping state. In the illustrated embodiment, the detection unit can be, but is not limited to, any of the following distance detection units capable of detecting the distance between two objects: a laser detection unit, an ultrasonic detection unit, an infrared detection unit, a limit switch, and a proximity switch. The detection unit 230 is disposed on the mounting base 210 and located outside the end of the detection block 220 away from the substrate 200, and is used to detect the distance P between it and the detection block 220. When the detection block 220 is located within the detection port 102, the distance P is equal to a preset safety distance P1, and a first signal is sent to the stamping device to cause the stamping unit of the stamping device to press the substrate 200 downwards. The first signal represents a detection head insertion signal. When the detection block 220 moves out of the detection port 102, the distance P is less than the safety distance P1, and a second signal is sent to the stamping equipment to make the stamping unit of the stamping equipment enter a non-stamping state. The second signal can be regarded as a non-positioning signal, and the non-stamping state refers to the stationary state when the stamping unit is lifted.

[0058] In this embodiment of the invention, detection ports 102 are equally spaced on the long side of the substrate 200, and the distance between each pair of adjacent detection ports 102 is designed to match the step size of the feeder, which serves as the basis for detecting whether the substrate 200 has been fed into place. Whether the detection block 220 located outside the long side of the substrate 200 enters the detection port 102 is used to determine whether the substrate 200 has been fed into place. The first signal issued by the detection unit 230 when the detection block 220 enters the detection port 102 is used as the trigger for whether the stamping equipment should perform stamping. When the detection block 220 enters the detection port 102, the detection unit 230 sends a first signal to both the stamping equipment and the feeder. After receiving the first signal, the feeder stops feeding. After receiving the first signal, the stamping equipment causes the stamping unit to press the substrate 200 downward. When the stamping unit moves upward, it sends a third signal to the feeder, and the feeder continues feeding. The substrate 200 drives the detection port 102 to move towards the stamping equipment. When the guide bevel of the detection port 102 moves towards the stamping equipment, it squeezes the detection head outward, causing the detection block 220 to move outward (towards the detection unit 230) and compress the elastic member 224. When the detection block 220 moves outward, the distance P between the detection block 220 and the detection unit 230 gradually decreases, becoming less than the safety distance P1. This serves as a trigger signal to lift the stamping unit upward and keep it stationary in a non-stamping state. In other words, the stamping unit remains stationary during the movement of the substrate 200, preventing accidental stamping, damage to products, and equipment. In summary, the substrate misfeeding prevention device of this invention, through its cleverly designed detection port 102, detection block 220, elastic element 224, and detection unit 230, achieves misfeeding prevention detection of the substrate 200. The movement of each component is achieved through its own force, eliminating the need for external driving force equipment, thus achieving precise control of the substrate 200 feeding position and improving product yield.

[0059] This invention also discloses a continuous feeding and stamping system for substrates, including a stamping device, a feeder for continuously feeding substrate 200 to the stamping device, a detection port stamping mechanism, a substrate anti-misfeeding detection device 100, and an edge trimming machine arranged sequentially along the conveying route. The feeder, detection port stamping mechanism, edge trimming machine, and stamping device are all electrically connected to the substrate anti-misfeeding detection device 100 to achieve signal transmission. The downward movement frequencies of the detection port stamping mechanism, edge trimming machine, and stamping unit are all consistent, meaning that the detection port stamping mechanism, edge trimming machine, and stamping device operate synchronously, each performing corresponding actions based on the first and second signals issued by the substrate anti-misfeeding detection device 100. The edge trimming machine is used to cut off the two long sides of the substrate 200, and the trimmed substrate 200 is conveyed to the stamping device for stamping.

[0060] The feeding step distance of the feeder is adapted to the distance between each pair of adjacent detection ports 102. With each step of the feeder, the corresponding detection port 102 is delivered to the position directly opposite the detection block 220. Without the obstruction of the long side of the substrate 200, the detection block 220 is immediately inserted into the detection port 102 under the elastic force of the elastic member 224. In this state, the distance P is equal to the safety distance P1 (the tolerance of the safety distance P1 can be limited to + / - 0.02 mm). This state indicates that the stamped part of the substrate 200 is located below the stamping unit (i.e., the substrate 200 is delivered into place). The detection unit 230 sends a first signal to the feeder, the detection port stamping mechanism, the trimming machine, and the stamping equipment. After the feeder, the detection port stamping mechanism, the trimming machine, and the stamping equipment receive the first signal simultaneously, the feeder stops feeding, and the detection port 102 stamping, the trimming machine, and the stamping equipment simultaneously stamp the substrate 200 downwards and move upwards. When the stamping equipment moves upward, it sends a third signal to the feeder, which continues to convey the substrate 200 forward. When the guide bevel of the detection port 102 moves toward the stamping equipment, it applies an outward thrust to the detection block 220. When the detection block 220 moves outward, the distance P between the detection block 220 and the detection unit 230 immediately becomes less than the safety distance P1. The detection unit 230 sends a second signal to the detection port stamping mechanism, the trimming machine, and the stamping equipment. The stamping equipment, the detection port stamping mechanism, and the trimming machine all remain in an upward-raised non-stamping state.

[0061] In this embodiment of the invention, the continuous feeding and stamping system for the substrate enables the substrate 200 to be accurately and effectively delivered into place via a substrate anti-misfeed detection device 100. A detection port stamping mechanism allows for the simultaneous forming of the detection port 102 as the substrate 200 is fed to the substrate anti-misfeed detection device 100. An edge trimming machine allows for the simultaneous trimming of the substrate 200 as it is conveyed to the stamping equipment. Both the detection port stamping mechanism and the edge trimming machine operate synchronously with the stamping equipment at the same frequency and are linked to the substrate anti-misfeed detection device 100. Stamping is controlled by a first signal and a second signal, resulting in a simple and efficient control logic that integrates multiple processes, saving processing time and improving processing efficiency.

[0062] Please see Figure 4 The present invention also discloses a method for detecting misfeeding of a substrate 200 during the feeding process of the substrate 200, comprising the following steps:

[0063] S110. Several equally spaced detection ports 102 are provided on one side 101 of the substrate 200 along the conveying direction;

[0064] In this step, the detection port punching mechanism, which is set between the feeder and the substrate misfeed detection device 100, can pre-punch the detection port 102 before the misfeed detection, thereby reducing the number of processes and improving efficiency.

[0065] S120, A detection block 220 is provided on one side 101 of the substrate 200 where the detection port 102 is provided, which can move in a direction perpendicular to the conveying direction (width direction);

[0066] S130, a detection unit 230 detects whether the detection block 220 is located within the detection port 102; wherein, the detection unit 230 is disposed outside the end of the detection block 220 away from the substrate 200; this step includes the following sub-steps:

[0067] S131. When the detection block 220 is located inside the detection port 102, the distance between it and the detection unit 230 is set as a safe distance P1.

[0068] S132. Detect the distance P between the detection unit 230 and the detection block 220.

[0069] S140. When the detection unit 230 detects that the detection block 220 is located within the detection port 102, it is considered that the substrate 200 has been moved into place, and a first signal is sent to the stamping equipment to cause the stamping equipment to press the substrate 200 downward. In this step, when the detection block 220 is located within the detection port 102, the distance P is equal to the preset safety distance P1: a first signal is sent to the stamping equipment to cause the stamping unit of the stamping equipment to press the substrate 200 downward. Preferably, a first signal is also sent to the detection port stamping mechanism and / or the trimming machine to cause the detection port stamping mechanism and / or the trimming machine and the stamping equipment to press the substrate 200 downward simultaneously. The detection port stamping mechanism is located between the substrate anti-misfeed detection device 100 (detection block) and the feeder, and the trimming machine is located between the substrate anti-misfeed detection device 100 and the stamping equipment.

[0070] S150. When the detection unit 230 detects that the detection block 220 has moved out of the detection port 102, it is considered that the substrate 200 has not been moved into place, and a second signal is sent to the stamping equipment to keep the stamping equipment in a non-stamping state. In this step, when the detection block 220 moves out of the detection port 102, the distance P is less than the safety distance P1: a second signal is sent to the stamping equipment to keep the stamping equipment in a non-stamping state. Preferably, a second signal is also sent to the detection port stamping mechanism and / or the edge trimming machine to make the detection port stamping mechanism and / or the edge trimming machine and the stamping equipment simultaneously in a non-stamping state.

[0071] In embodiments of the present invention, the trimming machine and the inspection port stamping mechanism can be considered as non-essential components. For example, in some embodiments, the inspection port 102 can be pre-formed before the stamping process, and the trimming process of the trimming machine can also be set after the stamping process.

[0072] Please see Figure 5 The present invention also discloses a continuous feeding stamping method for a substrate, comprising the following steps:

[0073] S210, The feeder continuously conveys the substrate 200 to the stamping equipment;

[0074] S220. A plurality of equally spaced detection ports 102 are provided on one side 101 of the substrate 200 along the conveying direction; wherein, the detection ports 102 are formed by a detection port punching mechanism provided between the feeder and the detection block 220 pressing the substrate 200 downward; the side of the detection port 102 away from the continuous punching station along the conveying direction is defined as a guide slope 102a that is away from the continuous punching station and inclined outward.

[0075] S230, the detection block 220 located on one side 101 of the substrate 200 where the detection port 102 is provided is brought into the detection port 102 under the elastic force of the elastic member 224;

[0076] S240, a detection unit 230 detects whether the detection block 220 is located within the detection port 102;

[0077] S250. When the detection unit 230 detects that the detection block 220 is located in the detection port 102, it is considered that the substrate 200 has been moved into place, and a first signal is sent to both the stamping equipment and the feeder; preferably, the detection unit 230 simultaneously sends a first signal to the stamping mechanism, the trimming machine, the stamping equipment and the feeder at the detection port.

[0078] S260, Stop feeding the feeder and make the stamping unit of the stamping equipment press the substrate 200 downward; preferably, make the detection port stamping mechanism, the trimming machine and the stamping unit of the stamping equipment all press the substrate 200 downward.

[0079] S270. After the stamping unit of the stamping equipment moves upward, it sends a third signal to the feeder. After receiving the third signal, the feeder continues to feed, causing the detection head to move out of the detection port 102 under the action of the guide inclined surface 102a.

[0080] S280. When the detection unit 230 detects that the detection block 220 has moved out of the detection port 102, it is considered that the substrate 200 has not been moved into place, and a second signal is sent to the stamping equipment. Preferably, the detection unit 230 simultaneously sends a second signal to the stamping mechanism of the detection port, the trimming machine and the stamping equipment.

[0081] S290, keep the stamping equipment in the non-stamping state after moving upward according to the second signal; preferably, keep the detection port stamping mechanism, the trimming machine and the stamping unit of the stamping equipment in the non-stamping state after moving upward.

[0082] In embodiments of the present invention, the inspection port stamping mechanism and the trimming machine can be considered as non-essential components, and the inspection port stamping process and the trimming process can be independent of the stamping process. For example, in some embodiments, the inspection port can be pre-formed before the stamping process, and the trimming process of the trimming machine can also be set after the stamping process.

[0083] The above embodiments merely illustrate preferred implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention should be determined by the appended claims.
