Description

Technical Field

[0001] This invention belongs to the technical field of sensor processing equipment, specifically a six-axis precision welding machine for sensors. Background Technology

[0002] A sensor is a device that can sensitively detect and effectively convert specific types of signals. Sensors not only have excellent external perception capabilities, capturing various changes in the surrounding environment, but also have the ability to accurately convert these complex and ever-changing external changes into electrical signals that are easy to process and analyze. Whether it is the rise and fall of temperature, the increase or decrease of pressure, the fluctuation of sound, the brightness of light, or the strength of electromagnetic fields, sensors can perform comprehensive and accurate detection and make corresponding responses and conversions accordingly.

[0003] In the current sensor manufacturing process, the chip needs to be precisely placed in a specific slot by hand and then moved directly under the welding head of the welding equipment. However, the method of relying on manual positioning has a significant problem: due to human factors, there may be slight deviations in the position of the sensor during placement. These deviations, although they may seem insignificant, can lead to serious quality problems in the subsequent welding process, making the welded sensor unable to meet the predetermined standards and thus considered a defective product. This not only affects production efficiency but also increases production costs, as defective products need to be reprocessed or discarded. Therefore, it is necessary to improve and optimize this process. Summary of the Invention

[0004] To address the problem mentioned in the background art that manual chip positioning during sensor processing can easily lead to minor deviations, affecting welding quality and production efficiency, this invention provides a six-axis precision welding machine for sensors.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a six-axis precision welding machine for sensors, including a base, a hollow cylinder one fixedly installed on the top of the base, a hollow cylinder two slidably installed on the inner wall of the hollow cylinder one, a stage fixedly installed on the top of the hollow cylinder two, a cross frame fixedly sleeved on the outer wall of the hollow cylinder one, and four sets of positioning mechanisms arranged inside the cross frame;

[0006] The positioning mechanism includes a linkage component one and a linkage component two. The linkage component one includes a slider that is slidably installed on the inner wall of the cross frame. Connecting rod one is respectively hinged to the outer walls of the two sides of the outer wall of the slider. The bottom of the two connecting rods one is hinged to the top of the base. Connecting rod two is respectively hinged to the outer walls of the two connecting rods one. The top of the two connecting rods two is hinged to the bottom of the platform.

[0007] Preferably, the second linkage component includes a rectangular groove formed on the outer wall of the cross frame, a rectangular horizontal block slidably installed on the inner wall of the rectangular groove, the side of the rectangular horizontal block near the slider being fixedly connected to the slider, a curved rod hingedly installed on the side of the rectangular horizontal block away from the slider, a positioning plate being fixedly installed on the top outer wall of the curved rod, and the positioning plate being slidably connected to the top of the platform.

[0008] Preferably, the top of the base is elastically connected to the bottom of the platform by a spring damping rod assembly, which is located at the center of hollow cylinder one and hollow cylinder two.

[0009] Preferably, limiting grooves are formed on the top and bottom inner walls of the cross frame, and limiting protrusions are fixedly installed on the top and bottom of the slider, with the two limiting protrusions slidably connected to the corresponding limiting grooves.

[0010] Preferably, L-shaped support frames are fixedly installed on the outer walls of both sides of the cross frame, and rotating rods are rotatably installed on the side of the two L-shaped support frames that are close to each other.

[0011] Preferably, the rotating rod passes through the bending rod, and the rotating rod is fixedly connected to the bending rod.

[0012] Preferably, an L-shaped track is fixedly installed on the outer side wall of the platform, and the L-shaped track is slidably connected to the bending rod.

[0013] Preferably, a rectangular slot is formed on the outer wall of the positioning plate, and the L-shaped track is slidably connected to the rectangular slot.

[0014] Preferably, the bending rod is configured with three folds, and the bending shape of the bending rod is trapezoidal.

[0015] Preferably, the four positioning mechanisms are designed in a square pattern, with the distribution direction consistent with the outer wall of the cross frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] This invention employs a linkage assembly consisting of a slider, connecting rod one, connecting rod two, a bending rod, and a positioning plate. This allows the slider to move smoothly within the cross frame, and the hinged connection of the connecting rod and the bending rod enables precise adjustment of the position of the stage and the sensor chip. Furthermore, the cooperation between the limiting protrusion and the limiting groove, as well as the sliding connection between the L-shaped track and the bending rod and the positioning plate, further enhances the accuracy and stability of the positioning.

[0018] This invention ensures structural stability throughout the welding process by incorporating a spring-damping rod assembly, a matching limiting protrusion and groove, and stable support from an L-shaped support frame and a rotating rod. The spring-damping rod assembly not only absorbs and disperses impact forces, effectively reducing vibration and noise, but also provides cushioning for the stable descent of the platform, preventing excessive movement or collisions due to inertia, thereby further improving welding precision and consistency.

[0019] This invention also has good adaptability, enabling it to handle sensors and materials of different sizes and shapes, meet different welding requirements, improve production efficiency, reduce production costs, and meet the needs of large-scale production. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1 to 8 As shown, the present invention provides a six-axis precision welding machine for sensors, including a base 1, a hollow cylinder 2 fixedly installed on the top of the base 1, a hollow cylinder 4 slidably installed on the inner wall of the hollow cylinder 2, a platform 5 fixedly installed on the top of the hollow cylinder 4, and a cross frame 3 fixedly sleeved on the outer wall of the hollow cylinder 2, with four sets of positioning mechanisms arranged inside the cross frame 3.

[0031] The positioning mechanism includes a first linkage component and a second linkage component. The first linkage component includes a slider 7 that is slidably installed on the inner wall of the cross frame 3. Connecting rods 8 are hinged to the outer walls of both sides of the slider 7. The bottom of both connecting rods 8 is hinged to the top of the base 1. Connecting rods 801 are hinged to the outer walls of both connecting rods 8. The top of both connecting rods 801 is hinged to the bottom of the platform 5.

[0032] By setting a positioning mechanism, when the stage 5 is subjected to greater downward pressure, the slider 7 will move towards the outer wall of the cross frame 3 within the limiting groove 301. The movement is achieved through the hinged connection between connecting rod 1 8 and connecting rod 2 801, causing them to rotate closer to each other around the hinge point. As the slider 7 moves, the stage 5 and the hollow cylinder 2 4 connected to it will also move downward together. During this process, the spring damping rod assembly 6 will be subjected to pressure and compressed, providing a buffer for the stable descent of the stage. While the slider 7 moves, it will drive the rectangular horizontal block 9 to move together. The rectangular horizontal block 9 is hinged to the curved rod 10. Therefore, when the rectangular horizontal block 9 moves, it drives the bending rod 10 and the positioning plate 1002 to slide in the opposite direction on the top of the platform 5 with the rotating rod 1001 as the hinge point. This sliding process adjusts the position of the sensor. When dealing with downward loads, the positioning mechanism of the device achieves precise adjustment and stable support of the sensor position through the cooperation of the slider 7, the linkage mechanism, the spring damping rod assembly 6, the bending rod 10, and the positioning plate 1002. This not only improves the positioning accuracy and consistency during the welding process, but also enhances the welding machine's adaptability to load changes, providing strong support for the manufacturing of high-precision sensors.

[0033] like Figure 2 , Figure 5As shown, the linkage component two includes a rectangular groove 302 formed on the outer wall of the cross frame 3. A rectangular horizontal block 9 is slidably installed on the inner wall of the rectangular groove 302. The side of the rectangular horizontal block 9 close to the slider 7 is fixedly connected to the slider 7. A curved rod 10 is hingedly installed on the side of the rectangular horizontal block 9 away from the slider 7. A positioning plate 1002 is fixedly installed on the top outer wall of the curved rod 10. The positioning plate 1002 is slidably connected to the top of the platform 5.

[0034] By setting a rectangular groove 302 and utilizing the spatial structure of the cross frame 3, a sliding trajectory is provided for the subsequent sliding installation of the rectangular horizontal block 9, thereby effectively improving the precise positioning of the sensor. One side of the rectangular horizontal block 9 is tightly fixedly connected to the slider 7, ensuring synchronous movement between the two. On the other side, a bent rod 10 is hinged to its outer wall, allowing the bent rod 10 to rotate around the rotating rod 1001 as a fixed point, thus achieving flexible adjustment and positioning. A positioning plate 1002 is fixedly installed on the top outer wall of the bent rod 10, enhancing its stability and allowing the positioning plate 1002 to slide smoothly on the top of the stage 5. The sliding connection between the positioning plate 1002 and the stage 5 further improves the stability and accuracy of the sensor chip during the welding process.

[0035] like Figure 2 As shown, the top of the base 1 and the bottom of the platform 5 are elastically connected by a spring damping rod assembly 6, which is located at the center of the hollow cylinder 2 and the hollow cylinder 4.

[0036] With the spring damping rod assembly 6 located at the center of hollow cylinder 2 and hollow cylinder 4, this layout not only optimizes space utilization but also ensures that the platform 5 maintains a stable motion state when subjected to external forces. The spring portion in the spring damping rod assembly 6 has excellent elastic recovery capabilities, effectively absorbing and dispersing external impact forces, thereby greatly reducing vibration and noise that may be generated during welding. This vibration reduction effect not only improves the accuracy and consistency of welding but also extends the service life of the welding machine.

[0037] like Figures 1 to 5 As shown, limit grooves 301 are respectively opened on the top and bottom inner walls of the cross frame 3, and limit protrusions 701 are fixedly installed on the top and bottom of the slider 7, and the two limit protrusions 701 are slidably connected to the corresponding limit grooves 301.

[0038] By creating limiting grooves 301 on the top and bottom inner walls of the cross frame 3, the limiting grooves 301 have precise dimensions and shapes that can match the limiting protrusions 701 on the slider 7. When the slider 7 slides within the cross frame 3, the limiting protrusions 701 are tightly embedded in the limiting grooves 301 and slide smoothly with the movement of the slider. This prevents the slider 7 from falling off during movement and avoids unstable phenomena such as jamming or shaking. The cooperation between the limiting protrusions 701 and the limiting grooves 301 not only achieves precise control of the movement of the slider 7, but also improves the stability and reliability of the entire welding system. During the welding process, this stable support and precise control are crucial for ensuring the accurate positioning of the sensor chip and avoiding the degradation of welding quality or the generation of unqualified products caused by minor deviations or shaking.

[0039] like Figures 5 to 6 As shown, L-shaped support frames 702 are fixedly installed on the outer walls of both sides of the cross frame 3. A rotating rod 1001 is rotatably installed on the side of the two L-shaped support frames 702 that are close to each other. The rotating rod 1001 passes through the bending rod 10 and is fixedly connected to the bending rod 10.

[0040] By combining the L-shaped support frame 702 and the rotating rod 1001, precise control and stable support of the bending rod 10 are achieved, which improves the accuracy and consistency of subsequent welding and makes the welding process smoother and more efficient. At the same time, due to its compact and stable structure, the welding machine also has good durability and reliability, and can operate stably for a long time to meet the needs of large-scale production.

[0041] like Figures 5 to 8 As shown, an L-shaped track 501 is fixedly installed on the outer side wall of the platform 5, and the L-shaped track 501 is slidably connected to the curved rod 10.

[0042] The L-shaped track 501 not only provides precise guidance but also achieves a tight sliding connection with the bending rod 10. This design ensures that the bending rod 10 can accurately move along the path of the L-shaped track 501 to the predetermined positioning position, thereby achieving precise fixation of the sensor chip, which improves the welding accuracy and consistency and reduces the generation of defective products.

[0043] like Figure 3 As shown, a rectangular slot is provided on the outer wall of the positioning plate 1002, and the L-shaped track 501 is slidably connected to the rectangular slot. The bending rod 10 is a three-fold setting, and the bending shape of the bending rod 10 is trapezoidal.

[0044] The sliding connection between the rectangular slot and the L-shaped track 501 provides stable and precise positioning for the sensor chip, ensuring that the chip remains in the predetermined position throughout the welding process, thereby greatly improving the welding accuracy and consistency. The three-fold design and trapezoidal bending shape of the bending rod 10 are also important guarantees for the accurate positioning of the welding machine. The three-fold design allows the bending rod 10 to flexibly adapt to different positioning requirements, while the trapezoidal bending shape further enhances its strength and stability. This design not only ensures that the bending rod 10 maintains a stable shape when subjected to external forces, but also ensures that the positioning plate 1002 maintains close contact with the L-shaped track 501 during the sliding process, thereby further improving the accuracy and stability of the positioning.

[0045] like Figure 1 As shown, the four positioning mechanisms are designed in a square pattern, and their distribution direction is consistent with the outer wall of the cross frame 3.

[0046] By using a quadrilateral-shaped positioning mechanism, the accuracy and stability of the sensor chip during placement and positioning are ensured. The four positioning mechanisms fix the chip from four directions, effectively avoiding minor deviations that may be caused by human operation. This not only improves the welding precision but also enables the welded sensor to meet higher quality standards, thereby greatly reducing the rate of defective products. At the same time, by reducing reprocessing and waste, production costs are effectively controlled, and production efficiency is significantly improved.

[0047] Working principle and usage process of this invention:

[0048] First, the six-axis precision welding machine for the sensor of this invention is fixedly installed within the working range of the welding head, ensuring the welding machine is stable and accurately positioned. The sensor to be welded is carefully placed above the stage 5, ensuring good contact between the sensor and the stage and that the position is approximately centered. After the sensor is placed down, the top of the stage 5 experiences a downward force under the sensor's own weight. This downward force is transmitted to the slider 7 through the connecting rod 801, preparing for subsequent positioning and adjustment. Then, another material to be welded is placed above the sensor using a clamping tool, ensuring the material's position and angle are correct to form a good welding contact with the sensor. The other material is placed on top of the sensor, pressing it down so that the stage 5 experiences greater downward pressure. The slider 7 moves within the limiting groove 301 towards the outer wall of the cross frame 3. This movement is achieved through the hinged connection between the connecting rod 8 and the connecting rod 801, causing them to rotate closer to each other around the hinge point. As the slider 7 moves, the stage 5 and the hollow cylinder 4 connected to it also move downward together. During this process... The spring-damping rod assembly 6 is subjected to pressure and compression, providing a buffer for the stable descent of the stage. As the slider 7 moves, it drives the rectangular horizontal block 9 to move as well. The rectangular horizontal block 9 is hinged to the bending rod 10. Therefore, when the rectangular horizontal block 9 moves, it drives the bending rod 10 and the positioning plate 1002 to slide in the opposite direction on the top of the stage 5 with the rotating rod 1001 as the hinge point. This sliding process adjusts the position of the sensor to align it with the design requirements, thereby ensuring the accuracy of the welding. After the sensor is accurately positioned, the welding function of the welding machine is activated to weld the sensor and the material. During the welding process, the welding head will move and weld precisely according to the preset parameters and program to ensure welding quality and efficiency. After welding is completed, the power of the welding machine is turned off, and the welded part is allowed to cool down for a period of time. The welding quality is checked using appropriate tools or equipment to ensure that the welded part is firm, flat, and free of defects. If the welding quality meets the requirements, the welded sensor and material can be removed from the stage for subsequent processing or testing.
