[0002] A sensor is a device that can keenly perceive and effectively convert specific types of signals. The sensor not only has excellent external perception capabilities and can capture various changes in the surrounding environment, but also has the ability to accurately convert these complex and changeable external changes into electrical signals that are easy to process and analyze. Whether it is the rise and fall of temperature, the increase and decrease of pressure, or the rise and fall of sound, the brightness of light, and the strength of the electromagnetic field, the sensor can perform comprehensive and accurate detection and make corresponding responses and conversions accordingly.

[0003] In the current sensor processing process, the chip needs to be placed manually and precisely in a specific slot, and then moved to just below the welding head of the welding equipment. However, there is a significant problem with the method that relies on manual positioning: due to human factors, the sensor may have slight positional deviations when placed. Although these deviations may seem insignificant, they may cause serious quality problems in the subsequent welding process, making the welded sensor unable to meet the established standards and thus be regarded as an unqualified product. This not only affects production efficiency, but also increases production costs, because unqualified products need to be reprocessed or discarded. Therefore, they need to be improved and optimized. Summary of the invention

[0004] In order to solve the problem in the above background technology that manual positioning of chips in sensor processing is prone to cause slight deviations, affecting welding quality and production efficiency, the present invention provides a six-axis precision welding machine for sensors.

[0005] To achieve the above object, the present invention provides the following technical solution: a six-axis precision welding machine for sensors, comprising a base, a hollow cylinder 1 is fixedly installed on the top of the base, a hollow cylinder 2 is slidably installed on the inner wall of the hollow cylinder 1, a stage is fixedly installed on the top of the hollow cylinder 2, a cross frame is fixedly sleeved on the outer wall of the hollow cylinder 1, and four groups of positioning mechanisms are arranged inside the cross frame;

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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] like Figures 1 to 8 As shown, the present invention provides a six-axis precision welding machine for sensors, comprising a base 1, a hollow cylinder 2 is fixedly installed on the top of the base 1, a hollow cylinder 4 is slidably installed on the inner wall of the hollow cylinder 2, a loading platform 5 is fixedly installed on the top of the hollow cylinder 4, a cross frame 3 is fixedly sleeved on the outer wall of the hollow cylinder 2, and four groups of positioning mechanisms are arranged inside the cross frame 3;

[0031] The positioning mechanism includes a linkage component 1 and a linkage component 2. The linkage component 1 includes a slider 7 slidably installed on the inner wall of the cross frame 3. Linkage rods 1 8 are hingedly installed on the outer walls of both sides of the outer wall of the slider 7. The bottoms of the two link rods 1 8 are hinged to the top of the base 1. Linkage rods 2 801 are hingedly installed on the outer walls of the two link rods 1 8. The tops of the two link rods 2 801 are hinged to the bottom of the loading platform 5.

[0032] By setting a positioning mechanism, when the stage 5 is subjected to a greater downward pressure, the slider 7 will move in the limiting groove 301 toward the outer wall of the cross frame 3, and the movement is connected through the hinge connection of the connecting rod 1 8 and the connecting rod 2 801, so that they rotate close to each other with the hinge point as the center. As the slider 7 moves, the stage 5 and the hollow cylinder 2 4 connected thereto will also move downward together. In this process, the spring damping rod assembly 6 will be subjected to pressure and compression, providing a buffer for the stable descent of the stage. When the slider 7 moves, it will drive the rectangular cross block 9 to move together. The rectangular cross block 9 is connected to the bending rod 10 by a hinge. Therefore, when the rectangular cross block 9 moves, it will drive 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 will adjust the position of the sensor. When the positioning mechanism of the device responds to the downward load, the slider 7, the connecting rod mechanism, the spring damping rod assembly 6, the bending rod 10 and the positioning plate 1002 cooperate to achieve precise adjustment and stable support of the sensor position, which not only improves the positioning accuracy and consistency during the welding process, but also enhances the adaptability of the welding machine to load changes, providing strong support for the manufacture of high-precision sensors.

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

[0034] By setting the rectangular groove 302 and utilizing the spatial structure of the cross frame 3, a sliding track is provided for the subsequent sliding installation of the rectangular cross block 9, thereby effectively improving the precise positioning of the sensor. One side of the rectangular cross block 9 is tightly and fixedly connected to the slider 7 to ensure the synchronous movement between the two. On the other side, a bending rod 10 is hingedly installed on its outer wall, so that the bending rod 10 can rotate around the rotating rod 1001 as a fixed point, thereby achieving flexible adjustment and positioning. The positioning plate 1002 is fixedly installed on the top outer wall of the bending rod 10, which first enhances the stability of the bending rod 10, and also enables 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 loading platform 5 are elastically connected via a spring damping rod assembly 6, and the spring damping rod assembly 6 is located at the center of the hollow cylinder 1 2 and the hollow cylinder 2 4.

[0036] The spring damping rod assembly 6 is located at the center of the hollow cylinder 1 2 and the hollow cylinder 2 4. The spring damping rod assembly 6 is located at the center of the hollow cylinder 1 2 and the hollow cylinder 2 4. This layout not only optimizes the space utilization, but also ensures that the stage 5 can maintain a stable state of motion when subjected to external force. The spring part in the spring damping rod assembly 6 has excellent elastic recovery ability, which can effectively absorb and disperse the impact force from the outside, thereby greatly reducing the vibration and noise that may be generated during the welding process. This shock absorption 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, limiting grooves 301 are respectively provided on the top and bottom inner walls of the cross frame 3, and limiting protrusions 701 are respectively fixedly installed on the top and bottom of the slider 7, and the two limiting protrusions 701 are respectively slidably connected with the corresponding limiting grooves 301.

[0038] By respectively opening limiting grooves 301 on the top and bottom inner walls of the cross frame 3, the limiting grooves 301 have precise size and shape, and can match with the limiting protrusions 701 on the slider 7. When the slider 7 slides in the cross frame 3, the limiting protrusions 701 will be tightly embedded in the limiting grooves 301 and slide smoothly with the movement of the slider, which not only prevents the slider 7 from falling off during movement, but also avoids the occurrence of unstable phenomena such as jamming or shaking. The cooperation between the limiting protrusions 701 and the limiting grooves 301 not only realizes the 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 to ensuring the precise positioning of the sensor chip, avoiding the decline in welding quality or the production of unqualified products due to slight deviations or shaking.

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

[0040] Through the combination of the L-shaped support frame 702 and the rotating rod 1001, precise control and stable support of the bending rod 10 are achieved, the accuracy and consistency of subsequent welding are improved, and the welding process is made 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 side outer wall of the loading platform 5, and the L-shaped track 501 is slidably connected to the curved rod 10.

[0042] By setting up the L-shaped track 501, the L-shaped track 501 not only has a precise guiding function, but also realizes a tight sliding connection with the bending rod 10. This design ensures that the bending rod 10 can accurately move to the predetermined positioning position along the path of the L-shaped track 501, thereby realizing precise fixation of the sensor chip, thereby improving the accuracy and consistency of welding and reducing the generation of unqualified products.

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

[0044] The sliding connection between the rectangular hole groove and the L-shaped track 501 provides stable and precise positioning for the sensor chip, ensuring that the chip can always remain in the predetermined position during the welding process, thereby greatly improving the welding accuracy and consistency. The three-fold setting 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 enables the bending rod 10 to flexibly adapt to different positioning requirements, and the trapezoidal bending shape further enhances its strength and stability. This design not only enables the bending rod 10 to maintain a stable shape when subjected to external force, but also ensures that the positioning plate 1002 always maintains close contact with the L-shaped track 501 during the sliding process, thereby further improving the accuracy and stability of positioning.

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

[0046] The positioning mechanisms are arranged in a rectangular shape to ensure the accuracy and stability of the sensor chip during placement and positioning. Four groups of positioning mechanisms fix the chip from four directions, effectively avoiding slight deviations that may be caused by human operation. This not only improves the welding accuracy, but also enables the welded sensors to meet higher quality standards, thereby greatly reducing the generation rate of unqualified products. At the same time, due to the reduction of reprocessing and waste, production costs are also effectively controlled and production efficiency is significantly improved.

[0047] The working principle and use process of the present invention:

[0048] First, the six-axis precision welding machine for sensors of the present invention is fixedly installed within the operating range of the welding head to ensure that the welding machine is stable and accurately positioned. The sensor to be welded is carefully placed above the stage 5 to ensure that the sensor is in good contact with the stage and that the position is roughly centered. After the sensor is lowered, the top of the stage 5 is subjected to a downward force under the action of the sensor's own gravity. The downward force will be transmitted to the slider 7 through the connecting rod 2 801 to prepare for subsequent positioning and adjustment. Then, a clamping tool is used to place another material to be welded above the sensor to ensure that the position and angle of the material are correct so as to form a good welding contact with the sensor. Another material to be welded is placed on the top of the sensor to press the sensor so that the stage 5 is subjected to greater downward pressure. The slider 7 will move in the limiting groove 301 toward the outer wall of the cross frame 3, and move through the hinged connection of the connecting rod 1 8 and the connecting rod 2 801 to rotate close to each other with the hinge as the center. As the slider 7 moves, the stage 5 and the hollow cylinder 2 4 connected thereto will also move downward together. In this process , the spring damping rod assembly 6 will be subjected to pressure and compression, providing a buffer for the stable descent of the stage. When the slider 7 moves, it will drive the rectangular cross block 9 to move together. The rectangular cross block 9 is connected to the bending rod 10 by a hinge. Therefore, when the rectangular cross block 9 moves, it will drive 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 will adjust the position of the sensor to align it with the design requirements, thereby ensuring the accuracy of welding. After the sensor is accurately positioned, finally, start the welding function of the welding machine to weld the sensor and the material. During the welding process, the welding head will perform precise movement and welding according to the preset parameters and procedures to ensure the quality and efficiency of welding. After welding is completed, turn off the power of the welding machine, and wait for a while for the welding part to cool down. Use appropriate tools or equipment to check the welding quality to ensure that the welding part is firm, flat and has no defects. If the welding quality meets the requirements, the welded sensor and material can be removed from the stage for subsequent processing or testing.
