Abstract
Description
Technical Field
[0001] This application relates to the field of battery production equipment technology, and in particular to a nailing device and a battery production line. Background Technology
[0002] The sealing nail welding process in the battery production line has high requirements for welding position and welding quality. When the sealing nail is automatically picked up and placed in the welding process, the placement of the sealing nail at the liquid injection port directly affects the welding efficiency and welding quality.
[0003] In related technologies, the pick-and-place mechanism uses a non-contact method when placing the nail, which cannot guarantee that the sealing nail will sink completely to the bottom when it falls into the injection port. This results in gaps between the sealing nail and the top cover or misalignment, affecting the stability of subsequent welding of the sealing nail. Utility Model Content
[0004] In view of the above problems, this application provides a nailing device and a battery production line, which aims to realize the synchronous action of nail placement and nail pressing to improve the accuracy of the nail placement position, thereby improving the welding stability of the subsequent sealing nails.
[0005] This application provides a top-mounting device, including a frame, a drive mechanism, and a suction cup mechanism. The drive mechanism is located on the frame. The suction cup mechanism is located on the frame and is drively connected to the drive mechanism. The drive mechanism drives the suction cup mechanism to move up and down. The suction cup mechanism includes a housing, a piston, and a suction cup. An airflow channel is formed inside the housing. The housing has a vacuum port and an air outlet communicating with the airflow channel. The horizontal plane of the air outlet is located above the horizontal plane of the vacuum port. The vacuum port is used to connect to a vacuum device. The piston is vertically and vertically located within the airflow channel. The piston is configured to control the connection and disconnection between the vacuum port and the air outlet. The suction cup is connected to the bottom of the piston. When the drive mechanism drives the suction cup mechanism to descend, the suction cup presses the sealing pin against the top cover. The suction cup is configured to receive an upward thrust when pressing the sealing pin. The thrust is the reaction force of the sealing pin, which drives the piston to rise through the suction cup, so that the vacuum port and the air outlet are connected. When the drive mechanism drives the suction cup mechanism to rise, the suction cup disengages from the sealing pin. The suction cup and the piston descend relative to the housing under the action of external force, thereby blocking the connection between the vacuum port and the air outlet.
[0006] In the technical solution of this application embodiment, by using the combined use of a drive mechanism and a suction cup mechanism, a vacuum negative pressure is first generated at the vacuum port under the action of an external vacuum device. Then, the suction cup of the suction cup mechanism picks up the sealing nail under the vacuum negative pressure generated at the vacuum port. When the drive mechanism drives the suction cup mechanism to descend, the suction cup places the sealing nail at the liquid injection port of the top cover and presses the sealing nail tightly onto the top cover to achieve the nail pressing action. At the same time, the suction cup will be subjected to an upward thrust when pressing the sealing nail. This thrust is the reaction force of the sealing nail. At this time, the suction cup drives the piston to rise, so that the vacuum port and the air outlet are connected to achieve vacuum breaking. This allows the vacuum port to be connected to the external atmosphere through the air outlet, achieving internal and external pressure balance. At this time, the suction cup releases the adsorption force on the sealing nail to achieve the nail release action. After the nail is released, the drive mechanism drives the suction cup mechanism to rise. At this time, the suction cup is detached from the sealing nail. At the same time, the suction cup and the piston can descend relative to the outer shell under the action of external force, which can block the connection between the vacuum port and the air outlet, thereby achieving the descent and reset of the suction cup and the piston. Therefore, this solution can achieve synchronous action of nail placement and nail pressing, thereby improving the accuracy of the sealing nail placement position and thus improving the welding stability of the sealing nail in the subsequent process.
[0007] In some embodiments, the piston has an elastic element at its top, with the end of the elastic element away from the piston connected to the inner wall of the airflow channel. When the drive mechanism drives the suction cup mechanism to descend, the suction cup drives the piston to rise to compress the elastic element. When the drive mechanism drives the suction cup mechanism to rise, the suction cup disengages from the sealing pin, and the elastic element releases pressure to drive the piston and suction cup to descend, thereby blocking the connection between the vacuum port and the air outlet. This design allows the suction cup mechanism to descend while the piston rises to compress the elastic element, at which point the elastic element accumulates energy. Then, when the drive mechanism drives the suction cup mechanism to rise, the suction cup disengages from the sealing pin, and the elastic element releases pressure to drive the piston and suction cup to descend, thereby blocking the connection between the vacuum port and the air outlet. Therefore, this embodiment can achieve automatic piston descent and reset with the elastic element design, eliminating the need for an additional drive mechanism to drive the piston descent and reset, thus reducing the power source output and lowering costs. Furthermore, the elastic element design can act as a buffer when the suction cup presses against the sealing pin, reducing the risk of damaging the sealing pin and the top cover.
[0008] In some embodiments, a buffer mechanism is also provided on the top of the elastic element. This design allows the buffer mechanism to provide secondary protection for the entire suction cup mechanism when the elastic element is compressed to its extreme state, preventing damage from overpressure and reducing the risk of crushing the sealing pin and top cover.
[0009] In some embodiments, the vacuum port and the exhaust port are located on opposite side walls of the housing. This design allows the vacuum port to be positioned further away from the exhaust port, making it easier to connect the vacuum port to external vacuum equipment.
[0010] In some embodiments, the upper nail device further includes an adapter mechanism, through which the suction cup mechanism is connected to the drive mechanism. The drive mechanism drives the adapter mechanism to rise and fall, thereby enabling the adapter mechanism to drive the suction cup mechanism to rise and fall. This design, by employing an adapter mechanism, makes it easier to connect the suction cup mechanism to the drive mechanism, so that during the process of the drive mechanism driving the adapter mechanism to rise and fall, the adapter mechanism can smoothly drive the suction cup mechanism to rise and fall in the vertical direction.
[0011] In some embodiments, the adapter mechanism includes a mounting component, a pressure sensor, and a trigger. The mounting component is drively connected to the drive mechanism, and a housing is disposed on the mounting component. The pressure sensor is disposed on the mounting component. The trigger is disposed on the outside of the housing, at least partially below the pressure sensor. When the suction cup presses the sealing nail onto the top cover, the trigger triggers the pressure sensor, causing the pressure sensor to detect the pressure of the suction cup on the sealing nail. With this design, when the drive mechanism lowers the suction cup mechanism, the suction cup places the sealing nail at the liquid inlet of the top cover and presses the sealing nail onto the top cover to achieve the nail-pressing action. Simultaneously, the suction cup experiences an upward thrust when pressing the sealing nail. At this time, the suction cup drives the piston to rise, and the suction cup transmits the pressure applied to the sealing nail to the trigger via the piston, causing the trigger to activate the pressure sensor. The pressure sensor can then acquire the pressure of the suction cup on the sealing nail for real-time detection. The pressure detected by the pressure sensor is used to control the descent distance of the drive mechanism driving the suction cup mechanism, ensuring quality during the sealing nail placement process and preventing product damage.
[0012] In some embodiments, the mounting component includes a connecting plate, a first mounting plate, and a second mounting plate; the connecting plate is drive-connected to the drive mechanism; the first mounting plate is disposed on the connecting plate, and a pressure sensor is mounted on the first mounting plate; the second mounting plate is disposed on the connecting plate and located below the first mounting plate, and a housing is mounted on the second mounting plate. With this design, during assembly, the pressure sensor can be first mounted on the first mounting plate, and then the housing can be mounted on the second mounting plate, allowing the entire suction cup mechanism to be mounted on the second mounting plate via the housing. Then, the connecting plate is used to mount the entire adapter mechanism and the entire suction cup mechanism onto the frame and drive-connected to the drive mechanism, thereby achieving quick installation of the adapter mechanism and the suction cup mechanism.
[0013] In some embodiments, the outer casing passes through the second mounting plate, and the outer side of the outer casing is further provided with a first limiting member and a second limiting member spaced apart. The first limiting member and the second limiting member abut against the top surface and the bottom surface of the second mounting plate, respectively. This design allows the outer casing to be passed through the second mounting plate during assembly. Then, the first limiting member is fitted onto the outer casing so that it abuts against the top surface of the second mounting plate, and the second limiting member is fitted onto the outer casing so that it abuts against the bottom surface of the second mounting plate. This allows the outer casing to be fixed to the second mounting plate by the limiting positions of the first and second limiting members, thereby improving the installation reliability of the outer casing and, consequently, the installation reliability of the suction cup mechanism.
[0014] In some embodiments, the drive mechanism includes a cylinder, a solenoid valve, and a speed control valve; the cylinder is mounted on the frame, and the suction cup mechanism is driven and connected to the cylinder; the solenoid valve is mounted on the frame and communicatively connected to the cylinder; the speed control valve is mounted on the frame and communicatively connected to the cylinder. With this design, when the pressure of the suction cup on the sealing nail reaches a predetermined value, the system controls the solenoid valve to stop outputting, thereby controlling the cylinder to maintain the existing downward pressure position. At this time, the pressure of the suction cup on the sealing nail remains constant, thus maintaining pressure on the sealing nail and improving the installation reliability of the sealing nail. Furthermore, the speed control valve can control the speed at which the cylinder drives the suction cup mechanism to rise and fall, enabling the suction cup mechanism to descend at an appropriate speed and avoiding damage to the product due to excessive downward pressure.
[0015] In some embodiments, the nailing device further includes a visual positioning mechanism, which is mounted on the frame and communicatively connected to the drive mechanism. The visual positioning mechanism is configured to detect the position of the sealing nail in real time to control the drive mechanism to adjust the placement position of the sealing nail. This design allows for precise positioning of the sealing nail by using a visual positioning mechanism to detect its position in real time, thereby improving the accuracy of the sealing nail placement and ultimately enhancing the welding stability of the sealing nail.
[0016] This application also provides a battery production line, including the aforementioned nailing device.

[0034] The sealing nail welding process in the battery production line has high requirements for welding position and welding quality. When the sealing nail is automatically picked up and placed in the welding process, the placement of the sealing nail at the liquid injection port directly affects the welding efficiency and welding quality.
[0035] In related technologies, the pick-and-place mechanism uses a non-contact method when placing the nail, which cannot guarantee that the sealing nail will sink completely to the bottom when it falls into the injection port. This results in gaps between the sealing nail and the top cover or misalignment, affecting the stability of subsequent welding of the sealing nail.
[0036] To address the aforementioned issues, this application proposes a nail-feeding device 100, designed to achieve synchronized nail placement and pressing actions, thereby improving the accuracy of the sealing nail placement position and thus enhancing the welding stability of the sealing nail. A detailed description follows with reference to the accompanying drawings and embodiments.
[0037] Please see Figures 1 to 5 In one embodiment of this application, the nailing device 100 includes a frame 10, a drive mechanism 20, and a suction cup mechanism 30. The drive mechanism 20 is disposed on the frame 10. The suction cup mechanism 30 is disposed on the frame 10 and is connected to the drive mechanism 20. The drive mechanism 20 drives the suction cup mechanism 30 to move up and down. The suction cup mechanism 30 includes a housing 31, a piston 32, and a suction cup 33. An airflow channel 311 is formed inside the housing 31. The housing 31 is provided with a vacuum port 312 and an air outlet 313 communicating with the airflow channel 311. The horizontal plane of the air outlet 313 is located above the horizontal plane of the vacuum port 312. The vacuum port 312 is used to connect to a vacuum device. The piston 32 is vertically and vertically disposed in the airflow channel. Inside channel 311, piston 32 is configured to control the connection between vacuum port 312 and air outlet 313; suction cup 33 is connected to the bottom of piston 32. When drive mechanism 20 drives suction cup mechanism 30 to descend, suction cup 33 presses the sealing pin against the top cover. Suction cup 33 is configured to receive an upward thrust when pressing the sealing pin. The thrust is the reaction force of the sealing pin, so that the piston 32 is driven to rise through suction cup 33, so that vacuum port 312 and air outlet 313 are connected; when drive mechanism 20 drives suction cup mechanism 30 to rise, suction cup 33 disengages from the sealing pin. Suction cup 33 and piston 32 descend relative to outer shell 31 under the action of external force, so as to block the connection between vacuum port 312 and air outlet 313.
[0038] In this embodiment, the frame 10 serves as the support frame for the entire nail-attaching device 100, supporting structural components such as the drive mechanism 20 and the suction cup mechanism 30. When the nail-attaching device 100 is applied to a battery production line, it can be mounted on a robotic arm or other driving equipment. Driven by the robotic arm or other driving equipment, the nail-attaching device 100 moves in three-dimensional space until the suction cup 33 picks up the sealing nail from the material frame or the previous process. Then, the nail-attaching device 100 moves until the suction cup 33 is positioned above the liquid injection port of the top cover. At this point, the drive mechanism 20 drives the suction cup mechanism 30 to descend, and the suction cup 33 places the sealing nail at the liquid injection port of the top cover. The vacuum port 312 and the air outlet 313 can be located on the same side wall of the outer casing 31, on opposite side walls of the outer casing 31, or on adjacent side walls of the outer frame, as long as the horizontal plane of the air outlet 313 is above the horizontal plane of the vacuum port 312. Vacuum equipment can be an external vacuum pump, vacuum generator, or other equipment capable of generating a vacuum.
[0039] The drive mechanism 20 can be a linear cylinder 21, or a structural component that combines the linear cylinder 21 with other transmission structures. The transmission structure can be a screw-nut combination, a gear-rack combination, etc., as long as it can smoothly drive the suction cup mechanism 30 to rise and fall vertically. When the drive mechanism 20 drives the suction cup mechanism 30 to rise, the suction cup 33 disengages from the sealing pin. At this time, the piston 32 can be driven to descend and reset under the action of the elastic element 34, or it can be driven to descend and reset under the action of an additional drive component.
[0040] The suction cup mechanism 30 can be raised and lowered under the action of the drive mechanism 20. When the drive mechanism 20 drives the suction cup mechanism 30 to descend, the suction cup 33 can press the sealing nail onto the top cover. At the same time, the suction cup 33 will be pushed upward in the opposite direction when pressing the sealing nail. The suction cup 33 can drive the piston 32 to rise in the airflow channel 311, so that the vacuum port 312 can be connected to the air outlet 313 through the airflow channel 311, thereby realizing the pressure relief and nail release action.
[0041] The outer shell 31 is the supporting shell for the entire suction cup mechanism 30, and is used to install the piston 32, suction cup 33 and other structures. The outer shell 31 can be directly connected to the drive mechanism 20, or it can be connected to the drive mechanism 20 through the adapter mechanism 40.
[0042] Piston 32 is vertically mounted within airflow channel 311, and the outer periphery of piston 32 forms a seal with the peripheral wall of airflow channel 311 to ensure the accuracy of piston 32 in controlling the opening and closing of vacuum port 312 and air outlet 313. When piston 32 moves up and down within airflow channel 311, it can have a first position and a second position; where piston 32 is in the first position, please refer to... Figure 4 The piston 32 is positioned between the vacuum port 312 and the outlet port 313 to block the communication between them; when the piston 32 is in the second position, please refer to... Figure 5 The piston 32 is positioned above the air outlet 313, allowing the vacuum port 312 to communicate with the air outlet 313. When the piston 32 is in the first position, the vacuum port 312 generates a vacuum negative pressure, which allows the suction cup 33 to have an adsorption force through the airflow channel 311, at which point the suction cup 33 can pick up the sealing nail. When the piston 32 is in the second position, the vacuum port 312 communicates with the outside atmosphere through the air outlet 313 to break the vacuum, at which point the suction cup 33 releases its adsorption force on the sealing nail.
[0043] The suction cup 33 is used to pick up or release the sealing nail. The suction cup 33 can also be connected to the bottom of the piston 32 by a connecting rod, screw or other connecting structure, as long as the piston 32 can be driven to rise when the suction cup 33 is subjected to an upward thrust.
[0044] In summary, in the technical solution of this application embodiment, by using the driving mechanism 20 and the suction cup mechanism 30 in cooperation, firstly, a vacuum negative pressure is generated at the vacuum port 312 under the action of an external vacuum device. Then, the suction cup 33 of the suction cup mechanism 30 picks up the sealing nail under the vacuum negative pressure generated at the vacuum port 312. When the driving mechanism 20 drives the suction cup mechanism 30 to descend, the suction cup 33 places the sealing nail at the liquid injection port of the top cover and presses the sealing nail tightly onto the top cover to achieve the nail pressing action. At the same time, the suction cup 33 will be subjected to an upward pushing force when pressing the sealing nail. This pushing force is the reaction force of the sealing nail. The suction cup 33 drives the piston 32 to rise, connecting the vacuum port 312 with the air outlet 313 to break the vacuum. This allows the vacuum port 312 to connect with the external atmosphere through the air outlet 313, achieving pressure balance. At this point, the suction cup 33 releases its suction force on the sealing nail to release it. After the nail is released, the drive mechanism 20 drives the suction cup mechanism 30 to rise, at which point the suction cup 33 detaches from the sealing nail. Simultaneously, the suction cup 33 and piston 32 can descend relative to the outer casing 31 under external force, thus blocking the connection between the vacuum port 312 and the air outlet 313, and achieving the descent and reset of the suction cup 33 and piston 32. Therefore, this solution can achieve synchronous nail release and nail pressing, improving the accuracy of the sealing nail placement and thus enhancing the welding stability of the sealing nail.
[0045] Please see Figures 4 to 5In one embodiment of this application, the top of the piston 32 is provided with an elastic element 34, and the end of the elastic element 34 away from the piston 32 is connected to the inner wall of the airflow channel 311. When the drive mechanism 20 drives the suction cup mechanism 30 to descend, the suction cup 33 drives the piston 32 to rise to compress the elastic element 34. When the drive mechanism 20 drives the suction cup mechanism 30 to rise, the suction cup 33 disengages from the sealing pin, and the elastic element 34 releases pressure to drive the piston 32 and the suction cup 33 to descend, so that the piston 32 blocks the communication between the vacuum port 312 and the air outlet 313.
[0046] The elastic element 34 is used to elastically connect the piston 32 to the inner wall of the airflow channel 311. When the suction cup 33 drives the piston 32 to rise, the elastic element 34 is compressed. When the suction cup 33 releases the thrust on the piston 32, the elastic element 34 releases the pressure. The elastic element 34 can be a structural component with elastic force, such as a spring, sheet, silicone, or rubber.
[0047] This design allows the suction cup 33 to drive the piston 32 to rise and compress the elastic element 34 when the drive mechanism 20 drives the suction cup mechanism 30 to descend, at which point the elastic element 34 accumulates energy. Then, when the drive mechanism 20 drives the suction cup mechanism 30 to rise, the suction cup 33 disengages from the sealing pin, and the elastic element 34 releases pressure to drive the piston 32 and the suction cup 33 to descend, so that the piston 32 blocks the connection between the vacuum port 312 and the air outlet 313. Therefore, this embodiment can achieve automatic descent and reset of the piston 32 with the design of the elastic element 34, without the need for an additional drive mechanism to drive the piston 32 to descend and reset, thus reducing the power source output and lowering costs. In addition, the design of the elastic element 34 can act as a buffer when the suction cup 33 presses against the sealing pin, reducing the risk of damaging the sealing pin and the top cover.
[0048] Please see Figures 4 to 5 In one embodiment of this application, a buffer mechanism 35 is also provided on the top of the elastic member 34.
[0049] The buffer mechanism 35 is used to further buffer the suction cup mechanism 30. The buffer mechanism 35 can also be a spring, sheet, silicone, rubber or other structural components.
[0050] With this design, when the elastic element 34 is compressed to its extreme state, the buffer mechanism 35 can provide secondary protection for the entire suction cup mechanism 30 to prevent damage from overpressure, while also reducing the risk of crushing the sealing pin and top cover.
[0051] Please see Figures 4 to 5 In one embodiment of this application, the vacuum port 312 and the air outlet 313 are respectively disposed on the opposite side walls of the outer casing 31.
[0052] This design allows the vacuum port 312 to be positioned further away from the outlet 313, making it easier to connect the vacuum port 312 to external vacuum equipment.
[0053] Please see Figures 1 to 2 In one embodiment of this application, the nailing device 100 further includes a transfer mechanism 40, and the suction cup mechanism 30 is connected to the drive mechanism 20 through the transfer mechanism 40. The drive mechanism 20 drives the transfer mechanism 40 to rise and fall, so that the transfer mechanism 40 drives the suction cup mechanism 30 to rise and fall.
[0054] The adapter mechanism 40 is used to connect the suction cup mechanism 30 to the drive mechanism 20. The adapter mechanism 40 can be a plate-shaped, block-shaped, or other shape of adapter structure, as long as it can stably connect the suction cup mechanism 30 to the drive mechanism 20. In some embodiments, in order to improve the smoothness of the adapter mechanism 40 during the lifting process, and to improve the stability of the suction cup mechanism 30 during the lifting process, a slider can be provided on the adapter mechanism 40, and a slide rail extending in the vertical direction can be provided on the frame 10, so that the slider slides in cooperation with the slide rail. In this way, when the drive mechanism 20 drives the adapter mechanism 40 to lift, the slider can slide smoothly along the slide rail.
[0055] This design, by using the adapter mechanism 40, makes it easier to connect the suction cup mechanism 30 to the drive mechanism 20, so that when the drive mechanism 20 drives the adapter mechanism 40 to rise and fall, the adapter mechanism 40 can smoothly drive the suction cup mechanism 30 to rise and fall in the vertical direction.
[0056] Please see Figure 2 In one embodiment of this application, the adapter mechanism 40 includes a mounting member 41, a pressure sensor 42, and a trigger member 43; the mounting member 41 is tractively connected to the drive mechanism 20, and the housing 31 is disposed on the mounting member 41; the pressure sensor 42 is disposed on the mounting member 41; the trigger member 43 is disposed on the outside of the housing 31, and the trigger member 43 is at least partially located below the pressure sensor 42; when the suction cup 33 presses the sealing nail onto the top cover, the trigger member 43 triggers the pressure sensor 42 so that the pressure sensor 42 detects the pressure of the suction cup 33 on the sealing nail.
[0057] Mounting component 41 is used to support and mount structural components such as pressure sensor 42, trigger 43, and suction cup mechanism 30, so as to connect the entire adapter mechanism 40 and the entire suction cup mechanism 30 to the drive mechanism 20. The mounting component 41 can be plate-shaped, block-shaped, or some other shape.
[0058] The pressure sensor 42 is a device that converts pressure into an electrical signal. It can convert the pressure applied to the pressure sensor 42 by the trigger 43 into an electrical signal to obtain the pressure of the suction cup 33 on the sealing nail.
[0059] The trigger element 43 is mounted on the housing 31. When the suction cup 33 presses the sealing pin onto the top cover, the suction cup 33 drives the piston 32 to rise, which in turn drives the trigger element 43 to rise. When the trigger element 43 rises to contact the pressure sensor 42 and continues to rise, the trigger element 43 squeezes the pressure sensor 42, thereby triggering the pressure sensor 42. Specifically, the top of the piston 32 can be connected to the trigger element 43 using an elastic element or other structural component to enable the piston 32 and the trigger element 43 to work together.
[0060] With this design, when the drive mechanism 20 drives the suction cup mechanism 30 to descend, the suction cup 33 places the sealing nail at the liquid injection port of the top cover and presses the sealing nail against the top cover to achieve the nail pressing action. At the same time, the suction cup 33 will be subjected to an upward thrust when pressing the sealing nail. At this time, the suction cup 33 drives the piston 32 to rise. Then, the suction cup 33 will transmit the pressure applied to the sealing nail to the trigger 43 through the piston 32, so that the trigger 43 will trigger the pressure sensor 42. At this time, the pressure sensor 42 can obtain the pressure of the suction cup 33 on the sealing nail to detect the pressure applied to the sealing nail in real time. Thus, the descent distance of the drive mechanism 20 driving the suction cup mechanism 30 is controlled by the pressure detected by the pressure sensor 42, ensuring the quality of the sealing nail placement process and avoiding damage to the product.
[0061] Please see Figure 2 In one embodiment of this application, the mounting component 41 includes a connecting plate 411, a first mounting plate 412, and a second mounting plate 413; the connecting plate 411 is drively connected to the drive mechanism 20; the first mounting plate 412 is disposed on the connecting plate 411, and the pressure sensor 42 is mounted on the first mounting plate 412; the second mounting plate 413 is disposed on the connecting plate 411 and located below the first mounting plate 412, and the housing 31 is mounted on the second mounting plate 413.
[0062] The connecting plate 411 can be a vertically placed plate-shaped structure, the first mounting plate 412 can be a horizontally placed plate-shaped structure, and the second mounting plate 413 can also be a horizontally placed plate-shaped structure. The height of the second mounting plate 413 protruding from the connecting plate 411 is greater than the height of the first mounting plate 412 protruding from the connecting plate 411. The connecting plate 411 has a first plate surface near the frame 10 and a second plate surface away from the frame 10. The first mounting plate 412 and the second mounting plate 413 can be mounted on the second plate surface. The pressure sensor 42 can be mounted on the side of the first mounting plate 412 near the second mounting plate 413. The housing 31 is mounted on the part of the second mounting plate 413 that protrudes from the first mounting plate 412, thereby mounting the entire suction cup mechanism 30 on the second mounting plate 413. The trigger 43 is connected to the housing 31, and the trigger 43 is at least partially located below the pressure sensor 42. The trigger 43 can be a Z-shaped or some other shaped structure.
[0063] With this design, during assembly, the pressure sensor 42 can be installed on the first mounting plate 412 first, and then the housing 31 can be installed on the second mounting plate 413. The entire suction cup mechanism 30 can be installed on the second mounting plate 413 through the housing 31. Then, the entire adapter mechanism 40 and the entire suction cup mechanism 30 can be installed on the frame 10 using the connecting plate 411 and connected to the drive mechanism 20, thereby achieving quick installation of the adapter mechanism 40 and the suction cup mechanism 30.
[0064] Please see Figure 2 In one embodiment of this application, the outer shell 31 passes through the second mounting plate 413, and the outer side of the outer shell 31 is also provided with a first limiting member 314 and a second limiting member 315 spaced apart. The first limiting member 314 and the second limiting member 315 abut against the top surface and the bottom surface of the second mounting plate 413, respectively.
[0065] The first limiting member 314 is used to limit the top of the second mounting plate 413 to prevent the suction cup mechanism 30 from descending relative to the second mounting plate 413. The first limiting member 314 can be a limiting collar, a limiting clamp, or other limiting structural members.
[0066] The second limiting member 315 is used to limit the bottom of the second mounting plate 413 to prevent the suction cup mechanism 30 from rising relative to the second mounting plate 413. The second limiting member 315 can be a limiting collar, a limiting clamp, or other limiting structural members.
[0067] With this design, during assembly, a second limiting member 315 can be first fitted onto the outer shell 31, and then the outer shell 31 can be inserted onto the second mounting plate 413 so that the second limiting member 315 abuts against the bottom surface of the second mounting plate 413. Then, a first limiting member 314 can be fitted onto the outer shell 31 so that the first limiting member 314 abuts against the top surface of the second mounting plate 413. Under the limiting of the first limiting member 314 and the second limiting member 315, the outer shell 31 can be fixed onto the second mounting plate 413, thereby improving the installation reliability of the outer shell 31 and thus improving the installation reliability of the suction cup mechanism 30.
[0068] Please see Figure 2 In one embodiment of this application, the drive mechanism 20 includes a cylinder 21, a solenoid valve 22, and a speed control valve 23; the cylinder 21 is mounted on the frame 10, and the suction cup mechanism 30 is connected to the cylinder 21 in a transmission manner; the solenoid valve 22 is mounted on the frame 10 and is communicatively connected to the cylinder 21; the speed control valve 23 is mounted on the frame 10 and is communicatively connected to the cylinder 21.
[0069] The solenoid valve 22 is used to control the cylinder 21 to start or stop working. The solenoid valve 22 can be connected to the cylinder 21 via an electrical connection cable or a wireless module.
[0070] The speed control valve 23 is used to control the speed at which the cylinder 21 drives the suction cup mechanism 30 to rise and fall. The speed control valve 23 can also be connected to the cylinder 21 via an electrical connection cable or a wireless module.
[0071] With this design, when the pressure of the suction cup 33 on the sealing nail reaches a predetermined value, the system controls the solenoid valve 22 to stop outputting, so that the cylinder 21 is controlled by the solenoid valve 22 to maintain the existing downward pressure position. At this time, the pressure of the suction cup 33 on the sealing nail is constant, so as to maintain the pressure on the sealing nail, thereby improving the installation reliability of the sealing nail. In addition, the speed control valve 23 can control the speed at which the cylinder 21 drives the suction cup mechanism 30 to rise and fall, so that the suction cup mechanism 30 can be driven to descend at an appropriate speed, avoiding damage to the product due to excessive downward pressure.
[0072] Please see Figure 1 In one embodiment of this application, the nailing device 100 further includes a visual positioning mechanism 50, which is disposed on the frame 10 and is communicatively connected to the drive mechanism 20. The visual positioning mechanism 50 is configured to detect the position of the sealing nail in real time so as to control the drive mechanism 20 to adjust the nailing position of the sealing nail.
[0073] The visual positioning mechanism 50 can be a CCD camera with a visual positioning system that can accurately position the sealing nail.
[0074] This design allows the visual positioning mechanism 50 to detect the position of the sealing nail in real time, thereby controlling the drive mechanism 20 to adjust the placement position of the sealing nail. This enables precise positioning of the sealing nail, improving the accuracy of the placement position and thus enhancing the welding stability of the sealing nail in the future.
