Description

Technical Field

[0001] The invention belongs to the technical field of diffusion welding, and in particular relates to an automatic parallelization and self-locking mechanism used in diffusion welding. Background Art

[0002] Polymer diffusion welding is also called diffusion welding. Diffusion welding refers to a solid-state welding method in which the workpiece is pressurized at high temperature without causing visible deformation and relative movement.

[0003] The diffusion welding machine is used to press and weld the ends of the workpiece (copper / aluminum foil soft connection). The existing technology generally adopts the principle of resistance welding: the pressing device presses the workpiece between the upper and lower graphite electrodes (welding heads), and a large current is passed between the two electrodes to make the workpiece conductive and heated to 60% to 80% of the melting point of the parent material, and the temperature is kept and the pressure is maintained to press and weld the layers of foil together.

[0004] When the existing diffusion welding is working, the graphite of the upper and lower welding heads squeeze the copper-aluminum foil soft row against each other, and at the same time, a large current is connected to heat the copper-aluminum foil soft row. The graphite of the upper and lower welding heads must be ensured to be parallel to each other to prevent the copper-aluminum foil soft row from having a cold weld due to uneven force during welding. The temperature of the graphite welding head reaches 600-650 degrees Celsius. The high temperature oxidizes the surface of the graphite, affecting the welding effect. The graphite welding head needs to be disassembled and polished, but the graphite of the upper and lower welding heads needs to be adjusted to be parallel during installation, which greatly affects production efficiency.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment 1:

[0031] like Figure 1-Figure 10As shown, the present invention provides an automatic paralleling self-locking mechanism for diffusion welding, comprising a first support plate 1, the first support plate 1 is fixedly mounted with a second support plate 3 through a support member 02, the first support plate 1 is fixedly mounted with a lower welding head 4, the second support plate 3 is fixedly mounted with a moving device 5, the moving device 5 is fixedly mounted with a self-locking leveling device 6, the self-locking leveling device 6 comprises a first substrate 7 and a second substrate 8, the second substrate 8 is movably connected to the first substrate 7 through a guide column 9, the second substrate 8 is fixedly mounted with a self-locking mechanism 10, the first substrate 7 is fixedly connected to the moving device 5, and the second substrate 8 is fixedly mounted with an upper welding head 11. The self-locking mechanism 10 comprises a driving cylinder 12, a push block 13 and a ball 14, the driving cylinder 12 drives and connects the push block 13, the first substrate 7 is provided with an assembly hole 15, and the push block 13 abuts against the assembly hole 15 through the ball 14. The push block 13 is provided with an inclined groove 16, and the inclined groove 16 abuts against the ball 14. The second substrate 8 is fixedly mounted with a guide groove assembly 17. The guide column 9 is fixedly mounted with a spring 18, one end of which elastically abuts against the first substrate 7. The first substrate 7 is fixedly mounted with a concave spherical component 19, and the second substrate 8 movably abuts against the concave spherical component 19 through a convex spherical component 20. The moving device 5 includes a driving device 21, a fixed part 22 and a moving part 23. The driving device 21 is driven and connected to the moving part 23 through a screw rod 24, and the fixed part 22 is slidably connected to the moving part 23 through a cross slide rail 25. The lower welding head 4 and the upper welding head 11 are both provided with a liquid cooling plate 26. The number of self-locking mechanisms 10 is 4. The first carrier plate 1 is fixedly mounted with a temperature sensor 27.

[0032] Through the above technical solution, the present invention drives the self-locking leveling device 6 to move up and down through the moving device 5. The self-locking leveling device 6 includes a first substrate 7 and a second substrate 8. The second substrate 8 is movably connected to the first substrate 7 through a guide column 9. The second substrate 8 is fixedly installed with a self-locking mechanism 10. The first substrate 7 is fixedly connected to the moving device 5. The second substrate 8 is fixedly installed with an upper welding head 11. During leveling, the worker first adjusts and fixes the graphite of the lower welding head 4, and the self-locking mechanism 10 is started and unlocked, so that the second substrate 8 can be slightly twisted relative to the first substrate 7. Start the moving device 5 and drive the self-locking leveling device 6 to move downward, so that the upper welding head 11 is close to the lower welding head 4, and the graphite of the upper welding head 11 is abutted against the graphite of the lower welding head 4. At this time, the graphite of the upper welding head 11 and the graphite of the lower welding head 4 are in a parallel state, and the self-locking mechanism 10 is started and locked to fix the second substrate 8 on the first substrate 7, that is, the graphite posture of the upper welding head 11 is fixed, and it always remains parallel to the graphite of the lower welding head 4. The moving device 5 rises and resets, and the graphite parallelism adjustment of the upper and lower welding heads is quickly and automatically completed, thereby improving production efficiency.

[0033] Embodiment 2:

[0034] like Figure 1-Figure 10As shown, the first support plate 1 of the present invention is a basic structure, and its function is to install and support other structures. The first support plate 1 is fixedly mounted with a second support plate 3 through a support member 2, and the second support plate 3 has the same function as the first support plate 1. A lower welding head 4 is fixedly mounted on the first support plate 1, and cooperates with an upper welding head 11 to complete the welding process of the copper-aluminum foil soft row. A moving device 5 is fixedly mounted on the second support plate 3, and the moving device 5 has the ability to move up and down, and is guided by a cross slide rail 25 to ensure the stability of the moving device 5 during movement.

[0035] A self-locking leveling device 6 is fixedly installed on the moving device 5. The self-locking leveling device 6 is the core component of the present invention, and its main function is to automatically level the graphite of the upper welding head 11 so that the graphite of the upper welding head 11 is parallel to the graphite of the lower welding head 4. This leveling process is crucial in the polymer diffusion welding process, because the copper-aluminum foil soft row needs to be evenly stressed during the polymer diffusion welding process to ensure the firmness of the welding and prevent the copper-aluminum foil from having a cold weld. The self-locking leveling device 6 is composed of a first substrate 7 and a second substrate 8. The second substrate 8 is movably connected to the first substrate 7 through a guide column 9, so that the second substrate 8 can perform a small torsional movement relative to the first substrate 7.

[0036] A self-locking mechanism 10 is fixedly installed on the second substrate 8, which is mainly used to lock the current posture of the second substrate 8, that is, the self-locking mechanism 10 can fix the current posture of the graphite of the upper welding head 11 to ensure the stability of the upper welding head 11 during the welding process. The first substrate 7 is fixedly connected to the moving device 5, and the second substrate 8 is fixedly installed with the upper welding head 11. When the present invention automatically adjusts the parallelism and self-locks, the worker first needs to adjust and fix the graphite of the lower welding head 4 in place, and then start the equipment. The self-locking mechanism 10 starts and unlocks the second substrate 8, so that the second substrate 8 can perform a small torsional activity relative to the first substrate 7.

[0037] After the moving device 5 is started, the upper welding head 11 on the self-locking leveling device 6 is driven downward to approach the lower welding head 4, so that the graphite of the upper welding head 11 is in contact with the graphite of the lower welding head 4. Due to the unlocked state of the self-locking mechanism 10, the graphite of the upper welding head 11 on the second substrate 8 can be slightly twisted when it contacts the graphite of the lower welding head 4. When the graphite of the upper welding head 11 is pressed against the graphite of the lower welding head 4, the moving device 5 stops moving and maintains the downward pressure. At this time, the graphite of the upper welding head 11 and the graphite of the lower welding head 4 are in a state of being parallel to each other, and the self-locking mechanism 10 is started and locks the second substrate 8, thereby fixing the second substrate 8 on the first substrate 7, that is, the posture of the graphite of the upper welding head 11 is locked, and it is always in a state of being parallel to the graphite of the lower welding head 4.

[0038] After completing the above steps, the moving device 5 rises to separate the graphite of the upper welding head 11 from the graphite of the lower welding head 4, and the automatic leveling and self-locking process is completed.

[0039] The moving device 5 uses a cross slide rail 25 to guide its movement, so as to ensure the stability of the moving device 5 during the movement, prevent the leveled graphite from swinging during the movement, and improve the welding effect.

[0040] After the worker completes the adjustment of the lower welding head 4, the device can be started to automatically complete the leveling of the upper welding head 11, which greatly reduces the time of manual adjustment and improves the degree of automation. The emergence of this mechanism solves the problem of frequent manual adjustment of the parallelism of the welding head in traditional welding, reduces the complexity of operation, and improves work efficiency.

[0041] Embodiment three:

[0042] like Figure 1-Figure 10 As shown, the self-locking mechanism 10 of the present invention includes a driving cylinder 12, a push block 13 and a ball 14. The driving cylinder 12 drives the movement of the push block 13 by air pressure, so as to achieve stable control of the second substrate 8 when locking or unlocking. The connection between the driving cylinder 12 and the push block 13 is direct, ensuring that the push block 13 can be smoothly extended and retracted under the action of the driving cylinder 12.

[0043] Four assembly holes 15 are provided on the first substrate 7. The assembly holes 15 are used to movably install the ball 14, so that the ball 14 cooperates with the push block 13 to complete the locking or unlocking state of the self-locking mechanism 10. When the push block 13 is extended, the push block 13 abuts against the ball 14 in a movable manner, so that the ball 14 abuts against the assembly hole 15 (i.e., the first substrate 7). The inclined groove 16 of the push block 13 is a key structural part of the push block 13. Its function is to movably abut against the ball 14. The inclined groove 16 is an inclined structure. When the push block 13 moves, it generates different sizes of squeezing force on the ball 14 to achieve the fixation of the second substrate 8.

[0044] There are four self-locking mechanisms 10, which are evenly distributed at the four corners of the second substrate 8. During operation, the working air pressure of the driving cylinders 12 of the four self-locking mechanisms 10 is kept consistent to ensure that the self-locking mechanisms 10 can work together during operation to generate a uniform force, thereby effectively fixing the second substrate 8.

[0045] When the self-locking mechanism 10 starts to lock, the driving cylinder 12 starts to start, and the push block 13 will extend outward. During this process, the inclined groove 16 of the push block 13 will abut against the ball 14 upward. Due to the abutment between the inclined groove 16 of the push block 13 and the ball 14, the push block 13 will generate a downward force at this time. This force acts directly on the second substrate 8, and because the four self-locking mechanisms 10 exert force at the same time, the second substrate 8 will be firmly locked on the first substrate 7, thereby ensuring that the entire structure is stable and motionless during the welding process, avoiding displacement caused by external factors.

[0046] When the self-locking mechanism 10 is in the unlocked state, the action of the driving cylinder 12 will retract the push block 13. At this time, the force of the inclined groove 16 of the push block 13 on the ball 14 is reduced, and the ball 14 can move freely relative to the assembly hole 15. At this time, the second base plate 8 can move slightly on the first base plate 7, which is convenient for fine adjustment during the leveling process.

[0047] In the specific operation process, the operation of the self-locking mechanism 10 depends on the precise control of the driving cylinder 12. The start and stop of the driving cylinder 12 controls the extension and contraction of the push block 13, thereby affecting the locking and unlocking of the self-locking mechanism 10. When locking is required, the working air pressure of the cylinder will be set to a suitable value, and the self-locking mechanism 10 locks the second substrate 8. In this process, the four self-locking mechanisms 10 work together to form a uniform force to maximize the stability of the second substrate 8. When the unlocking state is triggered, the driving cylinder 12 needs to be retracted at an accurate time to ensure that the push block 13 can be freely retracted. In this state, due to the reduction of the contact force of the inclined groove 16 between the push block 13 and the ball 14, the second substrate 8 can be fine-tuned to ensure the parallelism of the upper and lower welding heads 4 before welding. In this way, the self-locking mechanism 10 improves the efficiency during the welding process. The working state of the driving cylinder 12 must be kept consistent to ensure that the air pressure of all self-locking mechanisms 10 is the same to avoid uneven locking caused by changes in the air pressure of a single self-locking mechanism 10. This design requires the driving system to have high stability and accuracy to ensure that the parallelism between the upper welding head 11 and the lower welding head 4 is not affected during the welding process.

[0048] The second substrate 8 of the present invention is fixedly installed with a guide groove assembly 17. The main function of the guide groove assembly 17 is to work with the push block 13 in the self-locking mechanism 10. The push block 13 is driven by air pressure and realizes telescopic movement during operation, and the guide groove assembly 17 plays a role of protection and guidance. The setting of the guide groove assembly 17 can effectively prevent the push block 13 from directly rubbing against the second substrate 8 during the activity. If the push block 13 is in direct contact with the second substrate 8, the friction may cause wear on the surface of the second substrate 8, and long-term use may cause structural damage. The guide groove assembly 17 is used as a buffer to avoid direct contact between the push block 13 and the second substrate 8, prevent the second substrate 8 from being worn, and increase the service life of the second substrate 8. The inner surface of the guide groove is smooth and smeared with lubricating oil to reduce the friction resistance generated when the push block 13 moves, so that the push block 13 can pass smoothly. The side wall of the guide groove should have a certain height to prevent the push block 13 from deviating from the normal trajectory during movement. In this way, the guide groove assembly 17 can ensure that the push block 13 always slides in a straight line along the predetermined path, thereby improving the stability and accuracy of the movement. When the push block 13 moves in the guide groove, it not only reduces friction, but also obtains a smoother movement, which is crucial for the accuracy of the leveling process. By reducing friction and improving the smoothness of sliding, the guide groove assembly 17 provides better protection for the operation of the entire mechanism, ensuring that the push block 13 can be accurately positioned during leveling.

[0049] The guide post 9 of the present invention is fixedly installed with a spring 18. One end of the spring 18 elastically abuts against the first substrate 7, and the guide post 9 is fixedly installed on the second substrate 8. Through the elastic abutment of the spring 18, the first substrate 7 will have a tendency to approach the second substrate 8. The setting of this structure is crucial to the stability and reliability of the entire self-locking mechanism. When the self-locking mechanism 10 locks the second substrate 8, the spring 18 is compressed. When the self-locking mechanism 10 is started and the push block 13 is extended, the force applied downward by the push block 13 increases the distance between the second substrate 8 and the first substrate 7. At this time, the spring 18 generates a force due to compression. This force firmly fixes the second substrate 8 on the first substrate 7, ensuring that the relative position between the two is kept stable during the welding operation. The elastic characteristics of the spring 18 enable the first substrate 7 to achieve automatic adjustment and docking under the action of the self-locking mechanism 10. This automatic adjustment ability can produce a uniform pressure distribution during the welding process, ensuring the consistency and reliability of the welding effect. By compressing the spring 18, the first substrate 7 fixes the second substrate 8 in the self-locking state, thereby enhancing the strength of the welding connection.

[0050] The first substrate 7 of the present invention is fixedly mounted with a concave spherical component 19. The concave spherical component 19 cooperates with the convex spherical component 20 on the second substrate 8. The concave spherical component 19 and the convex spherical component 20 form a joint ball structure, so that the second substrate 8 can be twisted around the joint ball structure. Such a structural design can effectively improve the leveling efficiency of the welding head 11 on the second substrate 8. The shape of the concave spherical component 19 is designed to be an inner concave spherical surface, while the convex spherical component 20 is an outer convex spherical surface. The combination of the two forms a moving pivot, allowing the second substrate 8 to be flexibly adjusted during the leveling process.

[0051] Embodiment 4:

[0052] like Figure 1-Figure 10 As shown, the mobile device 5 of the present invention includes a driving device 21, a fixed part 22 and a moving part 23. The driving device 21 is connected to the moving part 23 through a screw rod 24, and the fixed part 22 is slidably connected to the moving part 23 through a cross slide rail 25. The setting of this structure is intended to improve the stability of the moving part 23 during the activity, and provide a reliable basis for the precise adjustment of the welding head during the welding process. The main function of the driving device 21 is to convert the rotational motion into linear motion through the screw rod 24, thereby driving the moving part 23 to move up and down. The use of the screw rod 24 can effectively increase the output torque of the driving device 21, so that when the moving part 23 needs to bear a large load, the driving device 21 can still maintain a stable operating state. Through this transmission mode, the operator can accurately control the position of the moving part 23 and achieve high-precision adjustment. This precise adjustment is crucial to the polymer diffusion welding process, because the welding quality often depends on the contact state and pressure distribution between the welding head and the workpiece. The fixed part 22 is connected to the movable part 23 through a cross rail 25, which improves the lateral force bearing capacity of the movable part 23. The setting of the cross rail 25 enables the movable part 23 to maintain a smooth motion trajectory with the support of the fixed part 22 when sliding. Such a design prevents deviation or jitter that may occur during the movement, thereby improving the stability of the overall system. When the movable part 23 is working, the external force it is subjected to is mainly transmitted to the fixed part 22 through the cross rail 25, ensuring the stability and accuracy during the movement. In actual welding, the operator adjusts the position of the movable part 23 by controlling the drive device 21, so that the upper welding head 11 moves up and down, and completes the welding and leveling process.

[0053] The lower welding head 4 and the upper welding head 11 of the present invention are both provided with a liquid cooling plate 26. The main function of the liquid cooling plate 26 is to block the heat conduction generated by the welding head during the welding process to prevent high temperature from causing damage to other devices. The high temperature environment has a direct impact on the performance and life of the welding equipment. Therefore, it is of great significance to use the liquid cooling plate 26 for effective temperature control. A plurality of guide holes are provided inside the liquid cooling plate 26, and these guide holes are designed to guide the flow of flowing coolant. By inputting flowing coolant, the liquid cooling plate 26 can quickly take away the heat generated by the welding head during the welding process and keep the welding head within a suitable working temperature range. The flow of coolant through the guide hole not only improves the cooling efficiency, but also ensures that the temperature of the welding head is evenly distributed, avoiding material damage or equipment failure caused by local overheating. During the welding process, the welding head is heated. If effective cooling measures are not taken, the welding head and its related components may lose performance due to overheating, or even cause permanent damage. Therefore, the application of the liquid cooling plate 26 can significantly extend the service life of the welding equipment and ensure the smooth progress of the welding operation. The liquid cooling plate 26 plays a dual role of protection and temperature stabilization in the welding system. The flowing coolant of the liquid cooling plate 26 can be selected from various types of coolants, such as water or a specific cooling liquid. When these coolants flow in the liquid cooling plate 26, they can quickly absorb and remove heat, ensuring that the welding head is maintained at a suitable temperature. Through the circulation of the coolant, the liquid cooling plate 26 can maintain a stable temperature level during the welding process, avoiding the negative effects caused by excessive temperature.

[0054] The first carrier plate 1 of the present invention is fixedly installed with a temperature sensor 27, which is a laser thermometer for measuring the temperature of the graphite of the welding head. The setting of the temperature sensor 27 plays a vital role in controlling the current during the welding process, and can ensure the stability of the welding temperature, thereby improving the welding quality. As a key monitoring device, the temperature sensor 27 can reflect the temperature change of the graphite of the welding head in real time. Through the laser thermometer, the temperature sensor 27 can accurately measure the temperature without contacting the welding head. This non-contact temperature measurement technology avoids the errors that may be caused by the traditional contact temperature sensor 27, ensuring the accuracy and reliability of temperature measurement. The use of the laser thermometer greatly improves the response speed of the temperature measurement, and can quickly capture the temperature change, thereby providing real-time data for the current regulation during the welding process. During the welding process, the temperature of the welding head directly affects the quality and efficiency of the welding. Too high a temperature may cause oxidation and damage to the graphite, while too low a temperature may cause poor welding, forming a cold weld or insufficient strength of the weld. Through accurate monitoring of the temperature of the welding head, the temperature sensor 27 can timely feedback the temperature information, and the operator can timely adjust the welding current according to the temperature change to keep the welding temperature within the set optimal range. This temperature control mechanism effectively prevents malfunctions caused by improper temperature during welding, thereby improving the stability and reliability of welding. The temperature sensor 27 is connected to the welding control system to form a closed-loop feedback control system. In this system, the temperature sensor 27 continuously monitors the temperature of the welding head and transmits the measured data to the control system. The control system determines the current welding state based on the temperature data and adjusts the welding current according to the preset temperature range. This feedback control mechanism enables the welding process to be adaptively adjusted, thereby ensuring that the welding temperature is always maintained at an appropriate level.
