[0002] Sensors have a wide range of applications, such as common pressure sensors and flow sensors. As precision instruments, sensors are more rigorous in their processing and manufacturing than general electronic equipment, and have higher requirements for accuracy and product yield.

[0003] In pressure sensors, the overload diaphragm is a core component, and its welding directly affects the overall reliability. In existing technologies, overload diaphragm energy storage welding is done manually, a process inherently prone to instability. First, the overload diaphragm must be manually placed and aligned. Before welding, conductive welding fixtures and positioning fixtures must be placed sequentially on top of the sensor. Second, it must be confirmed that the electrodes, welding fixtures, and overload diaphragm are concentric before welding can begin. Therefore, welding efficiency is low, and welding overload diaphragms of varying thicknesses requires manual adjustment of the welding program, frequently resulting in poorly welded overload diaphragms. The main reasons for these technical problems are human and tooling factors. The lack of standardization and uncertainty in manual operation leads to low yield and insufficient efficiency in the overload diaphragm welding process. Summary of the Invention

[0030] Refer to the accompanying drawings in this application specification. Figures 1 to 3As shown, an automatic overload diaphragm energy storage welding device according to a first preferred embodiment of this application is described below. The automatic overload diaphragm energy storage welding device is used for energy storage welding of an overload diaphragm and a base of a sensor. The device includes a welding machine assembly 10, a gripping mechanism 20, a positioning mechanism 30, and a controller 40. The controller 40 is electrically connected to the welding machine assembly 10, the gripping mechanism 20, and the positioning mechanism 30, and controls the workflow and working state of these components, achieving automated processing, reducing manual intervention, and improving product production efficiency.

[0031] The welding assembly 10 includes a working base plate 11, an energy storage welding machine 12 fixed on the working base plate 11, and a welding station 13, wherein the energy storage welding machine 12 is arranged adjacent to the welding station 13, and the welding head of the energy storage welding machine 12 is located directly above the welding station 13. The gripping mechanism 20 grips the overload diaphragm and the base to be processed and places them at the corresponding positions on the welding station 13 of the welding assembly 10. Then, the positioning mechanism 30 adjusts the relative positions of the overload diaphragm and the base, as well as the positions of the overload diaphragm and the base on the welding station 13 corresponding to the welding head of the energy storage welding machine 12. Finally, the energy storage welding machine 12 of the welding assembly 10 performs welding to weld the overload diaphragm and the base together.

[0032] The welding station 13 is disposed on the working substrate 11 and is electrically connected to the energy storage welding machine 12. That is, the welding station 13 is a conductive tooling used to hold and accommodate the overload diaphragm to be welded. The positioning mechanism 30 is disposed on one side of the welding station 13 of the welding machine assembly 10. After the base and the overload diaphragm are placed on the welding station 13, the positioning mechanism 30 adjusts the concentricity of the overload diaphragm and the base, and maintains the overload diaphragm and the base at a high degree of concentricity when the energy storage welding machine 12 is welding, so as to meet the requirements of overall product consistency and stability.

[0033] The welding station 13 is provided with a welding station 130, wherein the gripping mechanism 20 clamps the base and the overload diaphragm into the welding station 130 of the welding station 13 in sequence, and the positioning mechanism 30 adjusts the concentricity of the overload diaphragm located in the welding station 130 on one side of the welding station 13, and maintains the concentricity of the overload diaphragm during welding by the energy storage welding machine 12, so as to improve the accuracy and stability of welding.

[0034] After the base is clamped onto the welding station 130 of the welding station 13, the positioning mechanism 30 positions the base to the welding position of the welding station 130, which is directly opposite the welding head of the energy storage welding machine 12. When the overload diaphragm is moved above the base, the positioning mechanism 30 positions the base and the overload diaphragm, adjusting their concentricity. When the energy storage welding machine 12 is about to perform energy storage welding on the overload diaphragm, the positioning mechanism 30 repositions the overload diaphragm and the base, and the positioning mechanism 30 is provided with a positioning welding hole 301, which allows the welding head of the energy storage welding machine 12 to pass through for welding the overload diaphragm.

[0035] The positioning mechanism 30 has a positioning cavity 302, which communicates with the positioning weld hole 301, and the positioning weld hole 301 is located directly above the positioning cavity 302. The positioning cavity 302 of the positioning mechanism 30 is used to adjust the position of the base and the overload diaphragm, and to correct the concentricity of the base and the overload diaphragm. The welding head of the energy storage welding machine 12 can pass through the positioning weld hole 301 of the positioning mechanism 30 to weld the overload diaphragm located in the positioning cavity 302, preventing the overload diaphragm and the base from shifting positions during the welding process.

[0036] It is understood that the positioning structure 30 can not only be used to adjust the position of the overload diaphragm and the base, but also to restrict the movement of the overload diaphragm and maintain its concentricity during energy storage welding, which is beneficial to improving the product yield.

[0037] The positioning mechanism 30 further includes a positioning mechanism driver 31 and a gripper mechanism 32, wherein the positioning mechanism driver 31 is connected to the gripper mechanism 32 and can drive the gripper mechanism 32 to move. The gripper mechanism 32 can clamp the base and the overload diaphragm, correcting the concentricity of the base and the overload diaphragm. It is understood that the positioning cavity 302 and the positioning weld hole 301 of the positioning mechanism 30 are formed in the gripper mechanism 32.

[0038] The gripper mechanism 32 includes at least two gripper units 321, wherein the gripper units 321 of the gripper mechanism 32 are drivably connected to the positioning mechanism driver 31, and the positioning mechanism driver 31 drives the gripper units 321 of the gripper mechanism 32 to move openly and closeably.

[0039] When the positioning mechanism 30 positions the base and the overload diaphragm, the gripper unit 321 of the gripper mechanism 32 is driven open by the positioning mechanism driver 31, opening the positioning cavity 302 of the gripper mechanism 32. The positioning mechanism driver 31 drives the gripper unit 321 of the gripper mechanism 32 to clamp the base and the overload diaphragm, wherein the base and the overload diaphragm are clamped in the positioning cavity 302 by the gripper mechanism 32. Since the position of the positioning mechanism 30 is fixed, the position of the base and the overload diaphragm, which are fixed by the gripper mechanism 32 of the positioning mechanism 30, is also fixed. Preferably, in this preferred embodiment of the present application, the size of the positioning cavity 302 of the positioning mechanism 30 is adapted to the size of the base and the overload diaphragm. Therefore, the positioning mechanism 30 can adjust the position of the base and the overload diaphragm at the welding station 130 of the welding station 13 by clamping, and adjust the relative position of the base and the overload diaphragm during the clamping process, thereby correcting the concentricity of the overload diaphragm.

[0040] During the energy storage welding process, the gripper unit 321 of the gripper mechanism 32 of the positioning mechanism 30 closes, wherein the base and the overload diaphragm are held in the positioning cavity 302 of the gripper mechanism 32. At this time, the overload diaphragm and the base maintain a high degree of concentricity, and the positions of the overload diaphragm and the base are directly opposite to the position of the welding head of the energy storage welding machine 12, that is, the welding head of the energy storage welding machine 12 is directly opposite to the positioning welding hole 301 of the positioning mechanism 30, and the positioning welding hole 301 of the positioning mechanism 30 is located directly below the welding head of the energy storage welding machine 12. The gripper mechanism 32 of the positioning mechanism 30 clamps and fixes the overload diaphragm and the base, and the energy storage welding machine 12 welds the overload diaphragm and the base through the positioning welding hole 301 directly above the positioning mechanism 30. Since the overload diaphragm and the base are fixed by the positioning mechanism 30, their positions are fixed during the welding process. Therefore, they maintain a high degree of concentricity and do not need to be adjusted during the welding process, thus meeting the requirements of overall product consistency and stability.

[0041] It should be noted that in the prior art, when performing energy storage welding on an overload diaphragm, the overload diaphragm needs to be manually placed, and a complete set of conductive fixtures needs to be placed. Then, it is necessary to observe whether the workpiece and the fixtures are concentric before welding can be completed. In this preferred embodiment of the present application, the overload diaphragm can be automatically placed and its concentricity can be automatically corrected, maintaining a high degree of concentricity. It does not require adjustment for each welding, thus meeting the requirements of overall product consistency and stability.

[0042] The energy storage welding machine 12 includes a welding head 122 connected to a welding machine host 121, and a downward pressure cylinder 123 for driving the welding head 122 to move. The welding head 122 and the downward pressure cylinder 123 are disposed at the front end of the welding machine host 121, and the downward pressure cylinder 123 is connected to the welding head 122. The downward pressure cylinder 123 can drive the welding head 122 of the energy storage welding machine 12 to move vertically downward in the longitudinal direction.

[0043] The welding head 122 of the energy storage welding machine 12 can be driven by the pressure cylinder 123 to move along the positioning welding hole 301 of the positioning mechanism 30, that is, the welding head 122 is directly above the positioning welding hole 301 of the positioning mechanism 30.

[0044] The welding head 122 and the pressing cylinder 123 of the energy storage welding machine 12 are located at the front end of the welding machine host 121, and the welding head 122 and the pressing cylinder 123 are fixedly installed by a bracket.

[0045] The welding head 122 of the energy storage welding machine 12 can pass through the positioning welding hole 301 of the positioning mechanism 30 and weld the overload diaphragm and the base within the positioning cavity 302 of the positioning mechanism 30. Preferably, in this preferred embodiment of the present application, the outer diameter of the welding head 122 of the energy storage welding machine 12 is adapted to the diameter of the positioning welding hole 301 of the positioning mechanism 30. When the pressing cylinder 123 drives the welding head 122 to move toward the positioning welding hole 301 of the positioning mechanism 30, the positioning welding hole 301 of the positioning mechanism 30 guides the direction and position of the welding head 122, thereby aligning the welding head 122 with the welding position of the overload diaphragm and the base to be welded.

[0046] The controller 40 controls the positioning mechanism 30 to open and close, and the controller 40 controls the gripper mechanism 32 of the positioning mechanism 30 to adjust the position of the overload diaphragm and the base in a gripping manner, and to correct and maintain the concentricity of the overload diaphragm and the base in a gripping and fixing manner, so as to prevent the overload diaphragm and the base from separating from each other or from being too concentric during the welding process.

[0047] First, after the base is delivered to the welding station 13 by the gripping mechanism 20, the controller 40 controls the gripper mechanism 32 of the positioning mechanism 30 to close, and the gripper mechanism 32 positions the base to a specific position on the welding station 130 of the welding station 13. After positioning, the controller 40 controls the gripper mechanism 32 to open. The gripping mechanism 20 then transports the overload diaphragm to be welded above the base. The controller 40 controls the gripper mechanism 32 of the positioning mechanism 30 to close again, and the gripper mechanism 32 of the positioning mechanism 30 positions the overload diaphragm and the base to the specific position on the welding station 130 of the welding station 13. After positioning, the controller 40 controls the gripper mechanism 32 to open. When welding is required, the controller 40 controls the gripper mechanism 32 of the positioning mechanism 30 to close again, and the welding head 122 of the energy storage welding machine 12 passes through the positioning welding hole 301 of the positioning mechanism 30 to reach the positioning cavity 302 under the driving action of the downward pressure cylinder 123 to weld and fix the overload diaphragm and the base held in the positioning cavity 302.

[0048] Understandably, no manual intervention is required for installation and adjustment during this process. The entire process is automated, with the controller 40 controlling the welding machine assembly 10, the gripping mechanism 20, and the positioning mechanism 30. Furthermore, no adjustments are needed for each welding operation, thus meeting the requirements for overall product consistency and stability.

[0049] The gripping mechanism 20 includes a feeding mechanism 21, a discharging mechanism 22, and a diaphragm conveyor 23, wherein the feeding mechanism 21, the discharging mechanism 22, and the diaphragm conveyor 23 are arranged adjacent to the welding station 13. The feeding mechanism 21 transports the base to be processed to the welding station 130 of the welding station 13. The diaphragm conveyor 23 is used to transport the overload diaphragm to be processed to the base located above the base on the welding station 13. The processed base and the overload diaphragm are taken out by the discharging mechanism 22 and transported outward.

[0050] The feeding mechanism 21 of the gripping mechanism 20 includes a flipping mechanism 211 and a feeding gripper 212 disposed at the end of the flipping mechanism 211. The flipping mechanism 211 drives the feeding gripper 212 to rotate between a material picking position and the welding station 130 of the welding station 13. The feeding gripper 212 of the feeding mechanism 21 picks up the base to be processed from the material picking position and clamps the base to be processed into the welding station 130 of the welding station 13.

[0051] Preferably, in this preferred embodiment of the present application, the feeding claws 212 of the feeding mechanism 21 are disposed on both sides of the flipping mechanism 211. The feeding claws 212 of the feeding mechanism 21 grip the base to be processed on one side. After the flipping mechanism 211 drives the feeding claws 212 to flip, the feeding claws 212 at the other end are flipped to the material picking position, waiting to pick up the material.

[0052] The discharge mechanism 22 includes a rotating mechanism 221 and a discharge gripper 222 disposed at the end of the rotating mechanism 221. The rotating mechanism 221 can drive the discharge gripper 222 to rotate between the welding station 130 and a discharge position. The discharge gripper 222 of the discharge mechanism 22 can clamp the processed overload diaphragm and the base from the position of the welding station 130 and transport them to the discharge position.

[0053] Preferably, the discharge grippers 222 of the discharge mechanism 22 are arranged on both sides of the rotating mechanism 221. The discharge grippers 222 of the discharge mechanism 22 grip the base to be processed on one side. After the rotating mechanism 221 drives the discharge grippers 222 to flip, the discharge grippers 222 at the other end are flipped to the material picking position, waiting to pick up the material.

[0054] In a specific example of this application, the feeding mechanism 21 and the discharging mechanism 22 are symmetrically arranged relative to the welding station 13. That is, the feeding mechanism 21 transports the base to be processed to the welding station 13 from one side, and the discharging mechanism 22 removes the processed component from the other side opposite to the feeding mechanism 21.

[0055] The diaphragm conveyor 23 is used to convey the overload diaphragm to be processed to a specific position of the welding station 130 of the welding station 13, and the diaphragm conveyor 23 places the overload diaphragm above the base.

[0056] The diaphragm conveyor 23 includes a rotary conveying unit 231 and a suction unit 232 disposed at the end of the rotary conveying unit 231. The rotary conveying unit 231 of the diaphragm conveyor 23 can drive the suction unit 232 to move between a film picking position and the welding station 130 of the welding station 13. The suction unit 232 picks up the overloaded diaphragm to be processed from the film picking position. After the rotary conveying unit 231 moves the suction unit 232 to the welding station 130 of the welding station 13, the suction unit 232 places the overloaded diaphragm above the base.

[0057] The suction unit 232 of the membrane conveyor 23 acquires the overloaded membrane to be processed by gas adsorption. The membrane conveyor 23 further includes a position adjustment unit 233, wherein the position adjustment unit 233 is used to adjust the height position of the suction unit 232. When the overloaded membrane is lowered to the base, the position adjustment unit 233 lowers the position of the suction unit 232 so that the overloaded membrane is placed on the upper end of the base, rather than falling from a height onto the base.

[0058] The position adjustment unit 233 is located below the rotary conveying unit 231, and can drive the rotary conveying unit 231 and the suction unit 232 to move up and down along the height direction to adjust the height at which the suction unit 232 picks up and puts down.

[0059] The automatic energy storage welding equipment for overloaded diaphragms further includes a diaphragm storage mechanism 50, in which the overloaded diaphragm to be processed is placed. The diaphragm conveyor 23 retrieves the overloaded diaphragm to be processed from the diaphragm storage mechanism 50. The diaphragm storage mechanism 50 includes a memory and a position adjustment mechanism disposed within the memory. The memory has a storage chamber for holding the overloaded diaphragm, and the position adjustment mechanism is used to adjust the position of the overloaded diaphragm stored in the memory, so that the suction unit 232 of the diaphragm conveyor 23 can pick up the uppermost overloaded diaphragm.

[0060] The overloaded diaphragm to be processed is stacked in the memory of the diaphragm storage mechanism 50. The position adjustment mechanism can move up and down in the memory and lift the overloaded diaphragm to be picked up to a height position suitable for the pick-up unit 232 to pick up.

[0061] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations fall within the protection scope of this invention.
