[0002] Ceramic heating element is a medium that can make the heating wire heat up after being powered on. Ceramic heating element is widely used in life. For example, it is used in atomizers. Its function is to heat the heating wire through battery power, thereby generating heat.

[0003] After searching, the patent with patent application number CN202121420083.1 discloses a welding device for ceramic heating element pins. Although the device is used by setting a cutting chuck and a welding chuck, the welding chuck is located on the side of the cutting chuck that is delivered to the pins, and the cutting chuck is arranged on the cutting slide, and the cutting slide is driven by the cutting slide cylinder to slide back and forth toward the spot welding table; the welding chuck is arranged at the front end of the welding slide, and the welding slide is arranged below the cutting slide, and the welding slide is driven by the welding slide driver to slide toward the spot welding table; the welding chuck clamps the feeding pins. To connect with the ceramic heating element on the spot welding table, the ceramic heating element is clamped and fixed by the spot welding chuck and then the pins are welded through the spot welding head; the bending part of the foot folding test device has a downward inclined bending surface, and the bending test chuck clamps and sends the ceramic heating element with welded pins to the bending test table, and the bending part is driven by the bending cylinder to bend the pins to a set angle. However, when the device is used, it is still necessary to manually distinguish whether the welding is defective, which greatly increases the inspection time and cost, and manual inspection may not be able to detect welding defects in time, resulting in products with quality risks entering the market. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a welding device for ceramic heating element pins, which solves the problems raised in the background technology.

[0005] The solution of the present invention to solve the above technical problems is as follows: A welding device for a ceramic heating element pin comprises a base, a crossbeam is mounted on the base, a lifting frame is mounted on the crossbeam for transverse sliding through a transverse sliding module, and a welding module and a tin feeding component are mounted on the bottom end of the lifting frame; A tin coil rack is installed on the back of the crossbeam, a negative pressure tube is installed on the lifting frame, a first bracket is installed on the lifting frame behind the negative pressure tube, an industrial camera is installed on the first bracket, a feeding assembly is installed on the upper limit of the base, a limiting block is placed on the base, and the feeding assembly is limited on the base by the limiting block; The loading assembly is located in the base and is equipped with a feeding motor. A threaded rod is installed at the output end of the feeding motor. Guide rails are provided on both sides of the threaded rod. A sliding seat is slidably installed on the threaded rod. A connecting seat is connected to the sliding seat. A tray is installed on the connecting seat, and a workpiece is placed on the upper limit of the tray.

[0006] Based on the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, an angle of fifteen degrees is set between the industrial camera and the horizontal plane, and the industrial camera is used to take pictures and compare the pins after welding to determine whether the pins after welding meet the specifications.

[0008] The beneficial effects of adopting the above further scheme are: A 15-degree angle is deliberately set between the industrial camera and the horizontal plane. This design is not a random move, but the best shooting angle obtained after precise calculation and multiple tests. This angle enables the industrial camera to capture the subtle features of the welding pins from a more favorable perspective, including but not limited to the fullness of the solder joints, the uniformity of the solder distribution, and whether there are defects in the welding joints. The accurate capture of these key details undoubtedly greatly improves the accuracy and efficiency of welding quality inspection. At the same time, the 15-degree angle also effectively reduces the visual interference caused by light refraction or shadows on the workpiece surface, thereby ensuring that the captured image can truly and accurately reflect the welding quality. This is of vital importance for timely discovering and solving quality problems in the welding process and improving overall product quality.

[0009] Furthermore, the pallet is evenly provided with limiting grooves, and the workpiece is placed on the pallet through a rectangular array of limiting grooves. A plane coordinate system is established through the rectangular arrangement of the limiting grooves, thereby facilitating the industrial camera to record the position of the workpiece that does not meet the specifications.

[0010] The beneficial effects of adopting the above further scheme are: Limiting grooves are evenly arranged on the pallet, and the workpieces are placed in a rectangular array through these limiting grooves. This design not only achieves accurate positioning and stable placement of the workpieces, but also avoids welding quality problems caused by shaking or misalignment of the workpieces. More importantly, an intuitive and easy-to-understand plane coordinate system is established through the rectangular arrangement of the limiting grooves. When the industrial camera detects a workpiece whose welding quality does not meet the specifications, it can quickly record the specific location of the defective product based on this coordinate system. This function is crucial for subsequent quality tracing and defective product handling. It not only helps to quickly locate the problem workpiece and reduce the workload of quality inspection, but also provides strong data support for quality improvement in the production process.

[0011] Furthermore, the lifting frame is provided with a lifting motor, a screw module is installed at the output end of the lifting motor, a slider is slidably installed on the screw module, the negative pressure tube is installed on the slider, and the negative pressure tube is driven by the lifting frame to be lifted and lowered.

[0012] The beneficial effects of adopting the above further scheme are: The lifting motor acts as a power source, and drives the slider to slide through the screw module at the output end, thereby driving the negative pressure tube to lift and lower. This design not only improves the accuracy and stability of the lifting control, but also enables the negative pressure tube to be flexibly adjusted in height according to the needs of the welding operation. This flexible height adjustment capability not only helps to optimize the smoke collection effect during the welding process, but also ensures that the negative pressure tube will not collide with the workpiece or welding equipment during the welding process, thereby ensuring the safety and reliability of the welding operation.

[0013] Furthermore, a dust collecting pipe is provided at the bottom end of the negative pressure pipe, and a limiting frame is installed on the dust collecting pipe. The negative pressure pipe is supported and limited by the limiting frame, so that the negative pressure pipe is installed on the feeding assembly, and the smoke generated during welding is sucked out by the negative pressure pipe through negative pressure.

[0014] The beneficial effects of adopting the above further scheme are: A dust collecting pipe is set at the bottom of the negative pressure pipe, and is stably mounted on the feeding assembly through a limit frame. This design not only ensures the stability of the negative pressure pipe during the welding process, but also greatly improves the effect of smoke and dust collection. During the welding process, the negative pressure pipe quickly sucks the generated smoke and harmful gases into the dust collecting pipe through negative pressure suction, and then processes and discharges them through subsequent processing equipment. This design not only helps to keep the working environment clean and safe, and reduce the health risks of welding operations to operators, but also effectively extends the service life of the negative pressure pipe and dust collecting pipe, and reduces the maintenance cost of the equipment.

[0015] Furthermore, the welding module is provided with a fixing frame, which is fixed on one side of the negative pressure tube. An arc-shaped adjustment seat is slidably mounted on the fixing frame, and an electric heating head is slidably mounted on the adjustment seat. The electric heating head adjusts the angle with the workpiece through the adjustment seat.

[0016] The beneficial effects of adopting the above further scheme are: The fixed frame in the welding module is slidably mounted with an arc-shaped adjustment seat, and the electric heating head is slidably mounted on the adjustment seat. This flexible design allows the electric heating head to be accurately adjusted according to the shape and size of different workpieces. During the welding process, the electric heating head can contact the workpiece at the best angle to ensure the consistency and stability of the welding quality. This flexible adjustment capability not only improves the adaptability and flexibility of the welding operation, but also helps to reduce the difficulty and cost of welding caused by differences in workpiece shapes. For workpieces of different shapes and sizes, there is no need to replace the welding module or make complex adjustments. Simply adjusting the angle of the electric heating head can meet the welding needs.

[0017] Furthermore, the tin feeding assembly is installed on one side of the first bracket, and the tin feeding assembly is provided with a lifting cylinder, a lifting slider is installed at the output end of the lifting cylinder, a cantilever is installed on the lifting slider, and a guide tube is installed at the end of the cantilever, and the tin wire on the tin coil rack is guided to the electric heating head through the guide tube.

[0018] The beneficial effects of adopting the above further scheme are: The combination of the lifting cylinder and the lifting slider achieves accurate and stable feeding of the tin wire. During the welding process, the lifting cylinder flexibly adjusts the feeding speed and position according to the needs of the welding operation to ensure that the tin wire can be accurately and stably delivered to the electric heating head for welding. This automated design not only improves the automation and efficiency of the welding operation, but also helps to reduce the errors and safety hazards caused by manual feeding. For large-scale, high-efficiency welding production, this design undoubtedly has great advantages and value.

[0019] Furthermore, a groove is provided on the limit block, and a proximity switch is installed in the groove. When the loading assembly moves into place, the loading assembly blocks the proximity switch, thereby enabling the device to perform welding operations on the workpiece on the loading assembly after it is in place.

[0020] The beneficial effects of adopting the above further scheme are: The design of opening a groove on the limit block and installing a proximity switch realizes the precise positioning and automatic detection of the feeding component. When the feeding component moves into place, it blocks the trigger signal of the proximity switch, thereby triggering the welding equipment to perform the welding operation. This design not only improves the accuracy and reliability of the welding operation, but also helps to reduce welding defects and cost waste caused by positioning errors. This design is particularly important for workpieces that require high-precision welding operations. It can ensure that the welding operation is carried out at the right time and position, thereby avoiding welding quality problems caused by inaccurate positioning.

[0021] Furthermore, two groups of feeding components are provided on the base, and the lifting frame is driven by the lateral sliding module, and the workpieces on the two groups of feeding components are welded in turn by the welding module and the tin feeding component on the lifting frame.

[0022] The beneficial effects of adopting the above further scheme are: By driving the lifting frame to move by the horizontal sliding module, the workpieces on the two groups of loading components can be welded in turn. This design not only helps to shorten the production cycle and reduce production costs, but also improves the utilization rate and flexibility of the equipment. For workpieces that need to be produced in large quantities, this design undoubtedly has great advantages and value. It can significantly improve production efficiency and quality stability, creating more economic and social benefits for the enterprise.

[0023] Furthermore, a protective cover is provided on the outer side cover of the lifting motor, through which the lifting motor is shielded and protected, and heat dissipation holes are opened on the protective cover.

[0024] The beneficial effects of adopting the above further scheme are: The lifting motor is shielded and anti-slipped by the shield. At the same time, heat dissipation holes are opened on the shield to ensure good heat dissipation and stable operation of the motor. This design not only extends the service life and reliability of the lifting motor, but also helps to improve the stability and safety of the entire welding equipment. During the welding process, the lifting motor needs to withstand large loads and vibrations, so it is very important to effectively protect and dissipate heat for it. The design of the shield and heat dissipation holes can significantly reduce the failure rate and maintenance cost of the motor, providing a strong guarantee for the long-term stable operation of the equipment.

[0025] The present invention provides a welding device for ceramic heating element pins, which has the following beneficial effects: The equipment realizes the precise movement and positioning of the welding module and the tin feeding assembly through the horizontal sliding module, lifting frame, lifting motor and screw module, making the welding process highly automated. The electric heating head in the welding module can be adjusted by adjusting the angle through the adjustment seat to meet the needs of different workpieces, which increases the flexibility of the equipment. In addition, the equipment can perform welding operations on the workpieces on two groups of feeding assemblies in turn at the same time, greatly improving production efficiency.

[0026] The industrial camera is set at a 15-degree angle to the horizontal plane, which can take pictures and compare the pins after welding to ensure that the welding quality meets the specifications. The tin feeding component can accurately deliver the tin wire to the electric heating head through the lifting cylinder, cantilever and guide tube structures to ensure the continuity and stability of welding.

[0027] The setting of negative pressure pipe and dust collection pipe can effectively improve the working environment and protect the health of operators by sucking the smoke generated during welding through negative pressure.

[0028] There is a protective cover on the outside of the lifting motor to shield and protect the lifting motor. At the same time, there are heat dissipation holes on the protective cover to ensure the safe operation of the motor. The setting of the proximity switch can accurately detect whether the feeding component is in place to avoid safety hazards caused by misoperation.

[0029] The loading component realizes automatic loading and positioning of workpieces through feeding motors, threaded rods and guide rails. The evenly spaced limit slots on the pallet not only limit the position of the workpiece, but also establish a plane coordinate system through a rectangular arrangement, making it easier for industrial cameras to record the position of workpieces that do not meet the specifications, thereby improving the intelligence level of the equipment.

This design not only ensures the stability of the negative pressure pipe 10 during the welding process, but also greatly improves the effect of smoke collection. During the welding process, the negative pressure pipe 10 quickly sucks the generated smoke and harmful gases into the dust collecting pipe 1001 by means of negative pressure suction, and processes and discharges them through subsequent processing equipment. This design not only helps to keep the working environment clean and safe, and reduce the health risks of welding operations to operators, but also effectively prolongs the service life of the negative pressure pipe 10 and the dust collecting pipe 1001, and reduces the maintenance cost of the equipment. The lifting frame 7 is provided with a lifting motor 701, and the outer cover of the lifting motor 701 is provided with a shield, and the lifting motor 701 is shielded and protected by the shield, and the shield is provided with heat dissipation holes, and the lifting motor 701 is shielded and anti-slip treated by the shield. At the same time, the shield is also provided with heat dissipation holes to ensure good heat dissipation and stable operation of the motor. This design not only prolongs the service life and reliability of the lifting motor 701, but also helps to improve the stability and safety of the entire welding equipment. During the welding process, the lifting motor 701 needs to withstand large loads and vibrations, so it is very important to effectively protect and dissipate the heat for it. The design of the shield and the heat dissipation holes can significantly reduce the failure rate and maintenance cost of the motor, providing a strong guarantee for the long-term stable operation of the equipment. The output end of the lifting motor 701 is installed with a screw module 702, and a slider 703 is slidably installed on the screw module 702. The negative pressure tube 10 is installed on the slider 703. The negative pressure tube 10 is driven to lift by the lifting frame 7. The lifting motor 701 serves as a power source, and drives the slider 703 to slide through the screw module 702 at the output end, thereby driving the negative pressure tube 10 to lift. This design not only improves the accuracy and stability of the lifting control, but also enables the negative pressure tube 10 to be flexibly adjusted in height according to the needs of the welding operation.This flexible height adjustment capability not only helps to optimize the smoke collection effect during welding, but also ensures that the negative pressure tube 10 will not collide with the workpiece 205 or welding equipment during welding, thereby ensuring the safety and reliability of the welding operation. The welding module 3 is provided with a fixed frame 301, which is fixed to one side of the negative pressure tube 10. An arc-shaped adjustment seat 302 is slidably installed on the fixed frame 301, and an electric heating head 303 is slidably installed on the adjustment seat 302. The electric heating head 303 adjusts the angle with the workpiece 205 through the adjustment seat 302. The arc-shaped adjustment seat 302 is slidably installed on the fixed frame 301 in the welding module 3, and the electric heating head 303 is slidably installed on the adjustment seat 302. This flexible design enables the electric heating head 303 to accurately adjust the angle according to the shape and size of different workpieces 205. During the welding process, the electric heating head 303 can contact the workpiece 205 at the best angle, thereby ensuring the consistency and stability of the welding quality. This flexible adjustment capability not only improves the adaptability and flexibility of the welding operation, but also helps to reduce the welding difficulty and cost caused by the difference in the shape of the workpiece 205. For workpieces 205 of different shapes and sizes, there is no need to replace the welding module 3 or make complex adjustments. Simply adjusting the angle of the electric heating head 303 can meet the welding requirements. The lifting frame 7 is located behind the negative pressure tube 10 and is equipped with a first bracket 5. The first bracket 5 is equipped with an industrial camera 4. There is a 15-degree angle between the industrial camera 4 and the horizontal plane. The industrial camera 4 takes pictures and compares the pins after welding to determine whether the pins after welding meet the specifications. A 15-degree angle is deliberately set between the industrial camera 4 and the horizontal plane. This design is not a random move, but the best shooting angle obtained after precise calculations and multiple tests. This angle enables the industrial camera 4 to capture the subtle features of the welding pins from a more favorable perspective, including but not limited to the fullness of the solder joints, the uniformity of the solder distribution, and whether there are defects in the welding joints. The accurate capture of these key details undoubtedly greatly improves the accuracy and efficiency of welding quality inspection. At the same time, the fifteen-degree angle also effectively reduces the visual interference caused by light refraction or shadows on the surface of the workpiece 205, thereby ensuring that the captured image can truly and accurately reflect the welding quality. This is of vital importance for timely discovering and solving quality problems in the welding process and improving the overall product quality. The tin feeding component 11 is installed on one side of the first bracket 5. The tin feeding component 11 is provided with a lifting cylinder 1101. The output end of the lifting cylinder 1101 is provided with a lifting slider 1104. The lifting slider 1104 is provided with a cantilever 1102. The end of the cantilever 1102 is provided with a guide tube 1103. The tin wire on the tin coil rack 9 is guided to the electric heating head 303 through the guide tube 1103. The combination design of the lifting cylinder 1101 and the lifting slider 1104 realizes the precise feeding and stable supply of the tin wire.During the welding process, the lifting cylinder 1101 flexibly adjusts the feeding speed and position according to the needs of the welding operation to ensure that the tin wire can be accurately and stably delivered to the electric heating head 303 for welding. This automated design not only improves the automation and efficiency of the welding operation, but also helps to reduce the errors and safety hazards caused by manual feeding. For large-scale and high-efficiency welding production, this design undoubtedly has great advantages and value. The upper limit of the base 1 is installed with a feeding assembly 2. Two groups of feeding assemblies 2 are arranged on the base 1. The lifting frame 7 is driven by the horizontal sliding module 8. The welding module 3 and the tin feeding assembly 11 on the lifting frame 7 are used to perform welding operations on the workpieces 205 on the two groups of feeding assemblies 2 in turn. The lifting frame 7 is driven to move by the horizontal sliding module 8, so that the workpieces 205 on the two groups of feeding assemblies 2 can be welded in turn. This design not only helps to shorten the production cycle and reduce production costs, but also improves the utilization rate and flexibility of the equipment. For workpieces 205 that need to be produced in large quantities, this design undoubtedly has great advantages and value. It can significantly improve production efficiency and quality stability, and create more economic and social benefits for enterprises. A limit block 12 is placed on the base 1, and the feeding component 2 is limited on the base 1 by the limit block 12. A groove 1202 is provided on the limit block 12, and a proximity switch 1201 is installed in the groove 1202. When the feeding component 2 moves into place, the feeding component 2 blocks the proximity switch 1201, so that the device performs welding operation on the workpiece 205 on the feeding component 2 after it is in place. The design of providing the groove 1202 on the limit block 12 and installing the proximity switch 1201 realizes the precise positioning and automatic detection of the feeding component 2. When the feeding component 2 moves into place, it blocks the trigger signal of the proximity switch 1201, thereby triggering the welding equipment to perform welding operation. This design not only improves the accuracy and reliability of the welding operation, but also helps to reduce welding defects and cost waste caused by positioning errors. This design is particularly important for the workpiece 205 that requires high-precision welding operation. It ensures that welding operations are performed at the correct time and position, thus avoiding welding quality problems caused by inaccurate positioning.

[0035] Embodiment 2 In order to facilitate feeding and record the specific location of defective products, for example, Figures 1 to 9As shown, the present invention also includes: a feeding assembly 2 is located in the base 1 and is installed with a feeding motor 201, a threaded rod 202 is installed at the output end of the feeding motor 201, guide rails 203 are arranged on both sides of the threaded rod 202, a sliding seat 206 is slidably installed on the threaded rod 202, a connecting seat 207 is connected to the sliding seat 206, a tray 204 is installed on the connecting seat 207, a workpiece 205 is placed on the upper limit of the tray 204, and limiting grooves are evenly arranged on the tray 204, and the workpiece 205 is placed on the tray through a rectangular array of limiting grooves On pallet 204, a plane coordinate system is established through the rectangular arrangement of limit grooves, so that the industrial camera 4 can record the position of the workpiece 205 that does not meet the specifications. Limit grooves are evenly opened on the pallet 204, and the workpiece 205 is placed in a rectangular array through these limit grooves. This design not only realizes the precise positioning and stable placement of the workpiece 205, but also avoids welding quality problems caused by shaking or misalignment of the workpiece 205. More importantly, an intuitive and easy-to-understand plane coordinate system is established through the rectangular arrangement of the limit grooves. When the industrial camera 4 detects a workpiece 205 whose welding quality does not meet the specifications, it can quickly record the specific location of the defective product according to this coordinate system. This function is crucial for subsequent quality tracing and defective product processing. It not only helps to quickly locate the problem workpiece 205 and reduce the workload of quality inspection, but also provides strong data support for quality improvement in the production process.

[0036] Working principle: The feeding assembly 2 drives the threaded rod 202 to rotate through the feeding motor 201, so that the sliding seat 206 moves along the guide rail 203, thereby driving the workpiece 205 on the tray 204 to move to the welding position. The limit grooves on the tray 204 ensure that the workpieces 205 are neatly arranged in a rectangular array.

[0037] Through the cooperation of the lateral sliding module 8 and the lifting frame 7, the welding module 3 and the tin feeding assembly 11 are moved above the workpiece 205 to be welded. At the same time, the negative pressure pipe 10 is started to extract the smoke generated during the welding process.

[0038] The electric heating head 303 can adjust the angle by adjusting the seat 302 to meet the welding requirements of different workpieces. The lifting cylinder 1101 of the tin feeding assembly 11 drives the lifting slide 1104, the cantilever 1102, and the guide tube 1103 to move, and the tin wire is sent to the electric heating head 303 for welding.

[0039] After welding is completed, the industrial camera 4 takes a picture of the welded pins to capture an image of the welding area. The captured image is compared with a preset welding specification standard image, and an image processing algorithm is used to determine whether the welding quality meets the requirements. If it is found that the welding quality does not meet the requirements (such as crooked pins, incomplete welding, etc.), the workpiece 205 is marked as a defective product.

[0040] Since the pallet 204 is evenly provided with limiting grooves, the workpieces 205 are placed on the pallet 204 through a rectangular array of limiting grooves, so each workpiece 205 has a unique position coordinate on the pallet 204. When the industrial camera 4 identifies a defective product, the specific position of the defective product is recorded according to the position coordinates of the defective product on the pallet 204. This can be achieved by associating the position coordinates with the image information of the defective product and storing them in the control system of the device.

[0041] The control system can guide the operator or the automated equipment to remove the defective products from the tray 204 for rework or scrapping based on the recorded defective product location information. At the same time, the control system can also count the number and distribution of defective products to provide a basis for subsequent process improvement and quality control.
