Description

TECHNICAL FIELD

[0002] High polymer diffusion welding is also called diffusion welding, and diffusion welding refers to the solid-state welding method of pressing workpieces at high temperature without visible deformation and relative movement.

[0003] The diffusion welding machine is used to press and weld the end of the workpiece (copper / aluminum foil soft connection) into shape. The existing technology generally uses the principle of resistance welding: the lower pressing device presses the workpiece tightly between the upper and lower graphite electrodes (welding head), a large current is passed between the two electrodes to make the workpiece conductive and heated to 60% to 80% of the melting point temperature of the base material, and the heat and pressure are maintained to press and weld the foil pieces together.

[0004] The existing diffusion welding, when working, the graphite of the upper and lower welding heads is pressed against each other to heat the copper / aluminum foil soft connection, and a large current is connected to heat the copper / aluminum foil soft connection. The graphite of the upper and lower welding heads must be parallel to each other to prevent the copper / aluminum foil soft connection from being unevenly stressed during welding, which can cause virtual welding. The temperature of the graphite welding head reaches 600-650 degrees Celsius, which causes the surface of the graphite to oxidize at high temperature, 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 the production efficiency.

[0032] Through the above technical scheme, the utility model drives self locking leveling device 6 to move up and down by moving device 5, self locking leveling device 6 includes first base plate 7 and second base plate 8, second base plate 8 is movably connected first base plate 7 by guide column 9, second base plate 8 is fixedly installed with self locking mechanism 10, first base plate 7 is fixedly connected with moving device 5, second base plate 8 is fixedly installed with upper welding head 11, when leveling, worker first adjusts and fixes the graphite of lower welding head 4, self locking mechanism 10 is started and unlocked, so that second base plate 8 can be slightly twisted and moved relative to first base plate 7, starting moving device 5 drives self locking leveling device 6 to move down, so that upper welding head 11 is close to lower welding head 4, so that the graphite of upper welding head 11 is abutted and fitted on the graphite of lower welding head 4, at this time, the graphite of upper welding head 11 and the graphite of lower welding head 4 are in the state of mutual parallelism, self locking mechanism 10 is started and locked, so that second base plate 8 is fixed on first base plate 7, that is, the graphite posture of upper welding head 11 is fixed, always keeps mutual parallelism with the graphite of lower welding head 4, moving device 5 is raised and reset, and the graphite parallelism adjustment of two welding heads is quickly and automatically completed, and production efficiency is improved.

[0033] Embodiment two:

[0034] As Figures 1-10As shown, the first bearing plate 1 is a basic structure, which is used for mounting and supporting other structures. The first bearing plate 1 is fixedly installed with the second bearing plate 3 through the support 2, and the second bearing plate 3 has the same effect as the first bearing plate 1. The first bearing plate 1 is fixedly installed with the lower welding head 4, and cooperates with the upper welding head 11 to complete the welding process of the copper-aluminum foil soft cable. The second bearing plate 3 is fixedly installed with the moving device 5, which has the ability of moving up and down and is guided by the cross slide rail 25 to ensure the stability of the moving device 5 during movement.

[0035] The self-locking leveling device 6 is fixedly installed on the moving device 5. The self-locking leveling device 6 is the core component mechanism of the utility model, and the main function thereof 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 high polymer diffusion welding process, because the copper-aluminum foil soft cable needs to be uniformly stressed in the high polymer diffusion welding process, so as to ensure the firmness of welding and prevent virtual welding between the copper-aluminum foil. The self-locking leveling device 6 is composed of the first base plate 7 and the second base plate 8, and the second base plate 8 is movably connected with the first base plate 7 through the guide column 9, so that the second base plate 8 can be slightly twisted relative to the first base plate 7.

[0036] The self-locking mechanism 10 is fixedly installed on the second base plate 8 and is mainly used for locking the current posture of the second base plate 8, that is, the self-locking mechanism 10 can fix the current posture of the graphite of the upper welding head 11, so as to ensure the stability of the upper welding head 11 during welding. The first base plate 7 is fixedly connected with the moving device 5, and the second base plate 8 is fixedly installed with the upper welding head 11. When the utility model is automatically leveled and locked, the worker first needs to adjust and fix the graphite of the lower welding head 4 in place, and then starts the equipment. The self-locking mechanism 10 starts and unlocks the second base plate 8, so that the second base plate 8 can be slightly twisted relative to the first base plate 7.

[0037] After the moving device 5 is started, the upper welding head 11 on the self-locking leveling device 6 is driven to move 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 base plate 8 can be slightly twisted when it contacts the graphite of the lower welding head 4, and when the graphite of the upper welding head 11 is tightly attached to 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 mutually parallel state, the self-locking mechanism 10 is started and locked to the second base plate 8, so as to fix the second base plate 8 on the first base plate 7, that is, the posture of the graphite of the upper welding head 11 is locked and always in a mutually parallel state with the graphite of the lower welding head 4.

[0038] After the above steps are completed, 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 locking process is completed.

[0039] The moving device 5 is guided by the cross slide rail 25 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, starting the equipment will automatically complete the leveling of the upper welding head 11, greatly reducing the time spent on manual adjustments and improving the level of automation. The emergence of this mechanism solves the problem of frequent manual adjustment of the welding head parallelism in traditional welding, reduces operational complexity, and improves work efficiency.

[0041] Example 3:

[0042] like Figures 1-10 As shown, the self-locking mechanism 10 of this utility model includes a drive cylinder 12, a push block 13, and a ball bearing 14. The function of the drive cylinder 12 is to drive the push block 13 to move by air pressure, so as to achieve stable control of the second base plate 8 when locking or unlocking. The connection between the drive cylinder 12 and the push block 13 is direct, ensuring that the push block 13 can extend and retract smoothly under the action of the drive cylinder 12.

[0043] Four mounting holes 15 are provided on the first substrate 7. The mounting holes 15 are used to movably mount the ball bearings 14, so that the ball bearings 14 cooperate with the push block 13 to complete the locking or unlocking state of the self-locking mechanism 10. When the push block 13 extends, the push block 13 abuts against the ball bearings 14 in a movable manner, so that the ball bearings 14 abut against the mounting holes 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 make movable contact with the ball bearings 14. The inclined groove 16 is an inclined structure. When the push block 13 moves, it generates different magnitudes of squeezing force on the ball bearings 14 to fix 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 drive cylinders 12 of these four self-locking mechanisms 10 is kept consistent to ensure that the self-locking mechanisms 10 can work together to generate a unified force, thereby effectively fixing the second substrate 8.

[0045] When the self-locking mechanism 10 is activated, the drive cylinder 12 is activated, and the push block 13 extends outward. During this process, the inclined groove 16 of the push block 13 abuts against the ball 14. Due to the contact between the inclined groove 16 of the push block 13 and the ball 14, the push block 13 generates a downward force. This force acts directly on the second substrate 8, and because all four self-locking mechanisms 10 exert force simultaneously, the second substrate 8 is firmly locked onto the first substrate 7, thereby ensuring the stability of the entire structure during welding and preventing 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 cause the push block 13 to retract. At this time, the inclined groove 16 of the push block 13 reduces the force on the ball 14, 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, facilitating 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 retraction 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 an appropriate value, and the self-locking mechanism 10 locks the second base plate 8. In this process, the four self-locking mechanisms 10 work together to form a uniform force to maximize the stability of the second base plate 8. When the unlocking state is triggered, the driving cylinder 12 needs to retract at the right 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 base plate 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 of the welding process. The working state of the driving cylinder 12 must be consistent to ensure that the air pressure of all self-locking mechanisms 10 is the same, so as to avoid uneven locking due to changes in the air pressure of individual self-locking mechanisms 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 utility model discloses a second base plate 8 fixed mounting has the guide groove subassembly 17. The main function of guide groove subassembly 17 is with the push block 13 in self -locking mechanism 10 cooperation work. Push block 13 will be driven by air pressure and realize telescopic movement in the working process, and guide groove subassembly 17 plays the role of protection and guiding. The setting of guide groove subassembly 17 can effectively prevent push block 13 from directly rubbing with second base plate 8 in the activity process. If push block 13 directly contacts with second base plate 8, friction will possibly cause the wear and tear of the surface of second base plate 8, and long -term use can cause the damage of structure. Through guide groove subassembly 17 as buffer, avoid push block 13 directly with second base plate 8 contact, prevent second base plate 8 from being abraded, improve the service life of second base plate 8. The inside surface of guide groove is smooth and smears with lubricating oil, to reduce the friction resistance produced when push block 13 moves, make push block 13 can smoothly pass. The sidewall of guide groove should have certain height to prevent push block 13 from deviating from normal trajectory in the movement process. In this way, guide groove subassembly 17 can ensure that push block 13 always linearly slides along the predetermined path, thereby improving the stability and accuracy of movement. When push block 13 moves in guide groove, not only reduces friction, but also can obtain more stable movement, which is crucial for the accuracy of leveling process. By reducing friction and improving the smoothness of sliding, guide groove subassembly 17 provides better protection for the operation of the whole mechanism, ensuring that push block 13 can be accurately positioned when leveling.

[0049] The utility model discloses a guide column 9 fixed mounting has spring 18. The one end spring 18 elastically abuts at first base plate 7, and guide column 9 is fixedly installed on second base plate 8. Through the elastic abutment of spring 18, first base plate 7 will produce a tendency close to second base plate 8. The setting of this structure is crucial for the stability and reliability of the whole self -locking mechanism. When self -locking mechanism 10 locks second base plate 8, spring 18 is compressed. When self -locking mechanism 10 starts and will push block 13 stretch out, the power that push block 13 exerts downward makes the distance between second base plate 8 and first base plate 7 increase. At this time, spring 18 generates force due to compression. This force will firmly fix second base plate 8 on first base plate 7, ensure that the stable relative position between the two is kept in the welding operation. The elastic property of spring 18 makes first base plate 7 can realize automatic adjustment and butt joint under the action of self -locking mechanism 10. This automatic adjustment ability can produce uniform pressure distribution in the welding process, ensure the consistency and reliability of welding effect. Through the compression of spring 18, first base plate 7 fixes second base plate 8 in the self -locking state, thereby enhancing the strength of welding connection.

[0050] The first substrate 7 of this invention is fixedly mounted with a concave spherical assembly 19. This concave spherical assembly 19 cooperates with a convex spherical assembly 20 on the second substrate 8. The concave spherical assembly 19 and the convex spherical assembly 20 form a joint ball structure, allowing the second substrate 8 to rotate around this joint ball structure. This structural design effectively improves the leveling efficiency of the welding head 11 on the second substrate 8. The concave spherical assembly 19 is designed with an inwardly concave spherical surface, while the convex spherical assembly 20 is an outwardly convex spherical surface. The combination of the two forms a pivot for movement, allowing the second substrate 8 to be flexibly adjusted during leveling.

[0051] Example 4:

[0052] like Figures 1-10 As shown, the moving device 5 of this utility model includes a driving device 21, a fixing member 22, and a moving member 23. The driving device 21 is connected to the moving member 23 via a lead screw 24, while the fixing member 22 is slidably connected to the moving member 23 via a cross slide rail 25. This structure aims to improve the stability of the moving member 23 during its movement, providing a reliable basis for precise adjustment of the welding head during welding. The main function of the driving device 21 is to convert rotational motion into linear motion through the lead screw 24, thereby driving the moving member 23 to move up and down. The use of the lead screw 24 can effectively increase the output torque of the driving device 21, so that the driving device 21 can still maintain a stable operating state when the moving member 23 needs to bear a large load. Through this transmission method, the operator can precisely control the position of the moving member 23 and achieve high-precision adjustment. This precise adjustment is crucial for 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 component 22 is connected to the movable component 23 via a cross slide rail 25, which improves the lateral force bearing capacity of the movable component 23. The cross slide rail 25 ensures that the movable component 23 maintains a stable movement trajectory with the support of the fixed component 22 during sliding. This design prevents possible deviation or shaking during movement, thereby improving the overall system stability. When the movable component 23 is working, the external force it experiences is mainly transmitted to the fixed component 22 through the cross slide rail 25, ensuring stability and accuracy during movement. In actual welding, the operator adjusts the position of the movable component 23 by controlling the drive device 21, causing the upper welding head 11 to move up and down to complete the welding and leveling process.

[0053] The lower welding head 4 and the upper welding head 11 are both provided with liquid cooling plates 26. The main function of the liquid cooling plates 26 is to block the heat conduction generated during the welding process of the welding head, preventing high temperature from causing damage to other devices. High temperature environment has a direct impact on the performance and service life of the welding equipment, therefore, effective temperature control using the liquid cooling plates 26 is of great significance. The liquid cooling plates 26 are internally provided with multiple guide holes, which are designed to guide the flow of the flowing cooling liquid. By inputting the flowing cooling liquid, the liquid cooling plates 26 can quickly take away the heat generated by the welding head during the welding process, keeping the welding head within the appropriate working temperature range. The flow of the cooling liquid through the guide holes not only improves the cooling efficiency, but also ensures uniform distribution of the temperature of the welding head, 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 their performance due to overheating, and even cause permanent damage. Therefore, the application of the liquid cooling plates 26 can significantly prolong the service life of the welding equipment and ensure the smooth progress of the welding operation. The liquid cooling plates 26 play a dual role of protection and temperature stabilization in the welding system. The flowing cooling liquid of the liquid cooling plates 26 can be selected from various types of cooling liquids, such as water or special cooling liquids. These cooling liquids can quickly absorb heat and take it away when flowing in the liquid cooling plates 26, ensuring that the welding head maintains the appropriate temperature. Through the circulating flow of the cooling liquid, the liquid cooling plates 26 can maintain a stable temperature level during the welding process, avoiding the negative effects of excessive temperature.

[0054] The utility model discloses a first bearing plate 1 fixedly installed with temperature sensor 27, and the temperature sensor 27 is a laser thermometer, which is used for measuring the temperature of the welding head graphite. The setting of the temperature sensor 27 plays a crucial role in controlling the current during the welding process, which 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 welding head graphite 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 traditional contact type temperature sensors 27, ensuring the accuracy and reliability of temperature measurement. The use of the laser thermometer greatly improves the response speed of temperature measurement, which can quickly capture the temperature change, thereby providing real-time data for current adjustment 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 temperature may cause oxidation and damage of the graphite, while too low temperature may cause poor welding, resulting in false welding or insufficient strength of the welding points. 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, keeping the welding temperature within the set optimal range. This temperature control mechanism effectively prevents faults caused by improper temperature during the welding process, thereby improving the stability and reliability of the welding. The temperature sensor 27 is connected with the welding control system, forming 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 judges the current welding state according to the temperature data and adjusts the welding current according to the preset temperature range. This feedback control mechanism enables the welding process to be self-adaptively adjusted, thereby ensuring that the welding temperature always remains at an appropriate level.
