Description

Technical Field

[0001] This invention relates to the field of pen tip processing technology, specifically to an integrated device for iridium tip welding and post-weld visual online inspection. Background Technology

[0002] The nibs of writing instruments such as fountain pens and gold pens generally employ a structure with a welded hard, wear-resistant alloy ball (commonly known as an "iridium tip"). The iridium tip is the part of the pen nib that directly contacts the paper, and its material is mostly platinum group metals or high-hardness wear-resistant alloys. It is fixed to the tip of the pen nib by high-temperature welding, and the quality of the welding directly affects the durability and consistency of the pen nib.

[0003] Traditional iridium dotting processes for pen nibs are mostly carried out manually or semi-automatically. The main processes include: pen nib positioning, iridium nib loading, manual or pneumatic clamping, resistance welding, and post-weld visual inspection. Among these, post-weld inspection is mainly carried out by manual sampling or full inspection using magnifying glasses or microscopes. Production efficiency is significantly affected by the skill level of the workers, making it difficult to achieve high-speed automated production.

[0047] The principle of the integrated device for iridium tip welding and post-weld visual online inspection in this application: First, the display controller 11 is started, the equipment operating parameters are set, all components are started, the drive motor 101 starts working, and drives the drive column 102 and the outer upper and lower cams 103, clamping cam 104, lifting cam 105 and energizing cam 106 to rotate synchronously. When the pen tip vibrating plate 2 is started, the pen tip bodies 100 stored inside are arranged in an orderly manner through vibration and conveyed one by one through the feeding groove 21 to the slot 33 of the pen tip misalignment mechanism 3. Since the pen tip groove 321 of the push plate 32 is aligned with the slot 33 in the initial state, the single pen tip body 100 conveyed will be directly inserted into the pen tip groove 321 of the push plate 32, completing the automatic feeding and initial positioning of the pen tip and avoiding the simultaneous conveying of multiple pen tips. After the pen tip body 100 is inserted into the pen tip groove 321, the drive component A31 is activated, pushing the push plate 32 to slide along the inner side of the misaligned upright plate 34 away from the pen tip vibrating plate 2, so that the pen tip groove 321 is misaligned with the slot 33, preventing the pen tip body 100 from falling in again. At the same time, the pen tip body 100 in the pen tip groove 321 is precisely pushed to the electric clamp 44 close to the pen tip misalignment mechanism 3, realizing the misalignment separation and precise positioning of the pen tip body 100, and preparing for the subsequent clamping by the electric clamp 44. The drive component A31 retracts, causing the push plate 32 to reset, and the pen tip groove 321 aligns with the slot 33 again, ready to receive the next pen tip body 100, forming a continuous feeding cycle.

[0048] In the initial state, both sets of electric clamps 44 are in the lowest position, with one set close to the pen tip misalignment mechanism 3 and the other set close to the welding mechanism 5; at this time, the roller A433 is in contact with the concave surface of the upper and lower cams 103, the slide rail A43 is in the descending state, the electric clamps 44 have not risen, and the clamping conditions are met. The electric clamp 44 close to the pen tip misalignment mechanism 3 is activated to clamp the pen tip body 100 pushed below the pen tip groove 321, thus completing the clamping of the pen tip body 100 to be welded; at the same time, the electric clamp 44 close to the welding mechanism 5 is activated to clamp the pen tip body 100 that has been welded on the welding mechanism 5, thus completing the clamping of the welded pen tip body 100. After clamping is completed, the drive motor 101 drives the upper and lower cams 103 to continue rotating. When the first convex surface of the upper and lower cams 103 rotates to contact the roller A433 connected to the upper and lower cam lever 432, the convex surface generates an upward thrust on the roller A433, pushing the roller A433 to move upward. The roller A433 drives the slider B431 to slide upward along the shifting base 4311 through the upper and lower cam lever 432. The slider B431 drives the slide rail A43 to rise synchronously. The slide rail A43 drives the slider A42 and the two sets of electric clamps 44 to rise synchronously, so that the two sets of electric clamps 44 respectively drive the pen tip to be welded and the already welded pen tip to rise, disengage from the pen tip misalignment mechanism 3 and the welding mechanism 5, and complete the first rising action. After the two sets of electric clamps 44 rise to their highest positions, the drive unit B41 is activated, driving the slider A42 to slide along the slide rail A43 away from the pen tip misalignment mechanism 3 and towards the camera detection component 6, causing the two sets of electric clamps 44 to move horizontally: the electric clamp 44 close to the pen tip misalignment mechanism 3 moves to directly above the welding mechanism 5, and the electric clamp 44 close to the welding mechanism 5 moves to directly above the camera detection component 6; As the upper and lower cams 103 continue to rotate, the first convex surface separates from the roller A433, and the roller A433 again comes into contact with the concave surface of the upper and lower cams 103. The slide rail A43 descends under its own weight and the component's restoring force, causing the two sets of electric clamps 44 to descend to their lowest position and not rise. At this time, the electric clamp 44 holding the pen tip to be welded is located directly above the welding mechanism 5, ready to place the pen tip into the upper welding assembly 51. The electric clamp 44 holding the already welded pen tip is located directly above the camera inspection assembly 6, ready to perform post-weld inspection. After the electric clamp 44 descends to its lowest position, the electric clamp 44 holding the pen tip body 100 to be welded places the pen tip body 100 between the clamping pressure plate 5111 and the conductive clamping plate 5121 of the upper welding assembly 51, so that the upper welding assembly 51 clamps the pen tip body 100; the electric clamp 44 holding the welded pen tip places the welded pen tip in the detection position to detect the pen tip body 100. After the upper welding component 51 is clamped and the camera detection component 6 has completed its detection, the two electric clamps 44 release the pen tip body 100. When its second convex surface rotates to contact the roller A433, it pushes the roller A433 upward again, causing the two sets of electric clamps 44 to rise for the second time. Then the drive component B41 retracts, driving the slider A42 to reset along the slide rail A43, causing the two sets of electric clamps 44 to return to the initial horizontal position, that is, one set close to the pen tip misalignment mechanism 3 and the other set close to the welding mechanism 5. After descending, it clamps the new pen tip body 100 to be welded and the new pen tip body 100 that has been welded. During welding, the pen tip body 100 to be welded is placed between the clamping pressure plate 5111 and the conductive clamping plate 5121 of the upper welding assembly 51; then the welding process is started. In the initial state, the roller connected to the clamping cam lever 517 is in contact with the convex surface of the corresponding clamping cam 104, and the pen tip front plate 511 and the conductive moving plate B512 are in a state of being far apart. The drive motor 101 drives the opening cam 104 and the lifting cam 105 to rotate synchronously. When the concave surface of the opening cam 104 contacts the roller connected to the opening cam lever 517, the roller loses the support of the convex surface of the opening cam 104. Under the elastic force of the spring A515, the spring A515 pushes the pen tip pressure plate 5141 to move away from the dovetail fixing seat 513. The pen tip pressure plate 5141 drives the pen tip pressure front plate 511 to slide towards the conductive moving plate B512 through the slide rod A514. The clamping pressure plate 5111 approaches the conductive clamping plate 5121, and the pen tip body 100 is firmly clamped between the two, completing the clamping action. At this time, the part of the pen tip body 100 to be welded is aligned with the iridium in the iridium groove 5231 on the top of the ejector pin 523, ensuring accurate welding positioning; simultaneously, the convex surface of the lifting cam 105 contacts the roller C535 connected to the lifting cam lever 534, generating a thrust on the roller C535, causing the lifting cam lever 534 to rotate around the lifting cam lever connecting seat 536, and the other end of the lifting cam lever 534 rotates downward, applying force to the lower welding lifting plate drive plate 533 on the outer side of the lower welding lifting plate 53. The downward thrust pushes the lower welding lifting plate 53 to move downward. The lower welding lifting plate 53 drives the slider C531 to slide downward along the slide rail B532, and at the same time drives the slide rod B539 to slide downward along the lower welding fixing plate 537, and the spring B538 is compressed. The lower welding lifting plate 53 drives the ejector pin 523 to move downward synchronously through the conductive rod 524. The iridium groove 5231 at the top of the ejector pin 523 moves downward, so that an iridium granule in the hemispherical groove 5211 can be replenished into the iridium groove 5231. After the iridium granules are replenished, the lifting cam 105 continues to rotate, the convex surface separates from the roller C535, the roller C535 loses its thrust, and the lifting cam lever 534 resets; at this time, the spring B538 returns to its natural extension and contraction state, pushing the lower welding lifting plate 53 upward to reset, and the lower welding lifting plate 53 drives the ejector pin 523 and the conductive rod 524 to rise synchronously, driving the iridium granules in the iridium granule groove 5231 to move upward, so that the iridium granules accurately fit the welding part of the pen tip body 100, ensuring that the iridium granules and the pen tip are in close contact; During the contact process, the energized cam 106 on the drive motor 101 rotates, and its concave surface rotates to align with the triangular end of the guide rod 91. The guide rod 91 is pushed by the guide rod connecting assembly 92 to fit against the concave surface of the energized cam 106. The guide rod 91 drives the electrode seat 93 to move synchronously, and the electrode seat 93 drives the bottom electrode rod A94 to move, so that the electrode rod A94 and the electrode rod B95 are closely attached. At this time, the circuit is connected, and the current passes through the electrode rod B95, the electrode rod A94, the conductive rod 524, the ejector pin 523 and the conductive moving plate B512, and transmits the current to the contact part between the iridium tip and the pen tip body 100. High temperature is generated through the resistance heating effect to realize the resistance welding of the iridium tip and the pen tip. At the same time as welding starts, the control vent pipe 54 of the chassis 12 opens, and a continuous inert gas flow, such as argon, is introduced into the welding area between the iridium tip and the pen tip. Argon forms a protective gas layer at the welding area, which isolates the air and prevents the welding area from oxidizing, avoiding defects such as oxidation spots and cold solder joints, and greatly improving the welding quality and pen tip durability. After the preset welding time is reached, the energized cam 106 continues to rotate, causing its convex surface to contact the triangular end of the guide rod 91, generating an outward thrust on the guide rod 91. This pushes the guide rod 91 along the guide rod connecting assembly 92 in a direction away from the drive assembly 10, thereby causing the guide rod 91 to move synchronously with the electrode seat 93. The electrode seat 93 then moves the bottom electrode rod A94, causing electrode rod A94 to separate from electrode rod B95, disconnecting the circuit and stopping the welding operation; thus completing the welding process. After welding, the clamping cam 104 continues to rotate, and its convex surface contacts the roller B518 connected to the pen tip front plate 511. The convex surface of the clamping cam 104 exerts a pushing force on the roller B518 connected to the pen tip front plate 511, pushing the pen tip front plate 511 to slide away from the conductive moving plate B512. The slide bar A514 drives the pen tip rear plate 5141 to move, the spring A515 is compressed, and the clamping pressure plate 5111 separates from the conductive clamping plate 5121, completing the release action. Meanwhile, the ejector pin 523 descends again with the lower welding lifting plate 53, entering the next iridium granule replenishment cycle. This process is repeated sequentially to achieve a continuous cycle of iridium granule replenishment, welding positioning, and reset replenishment, without the need for manual intervention.

[0049] During testing, the display controller 11 controls the recognition camera 61 to start, with the lens aimed at the welding area of ​​the pen tip, capturing high-definition images of the welding area in real time. The shooting angle precisely covers the connection between the iridium tip and the pen tip, ensuring no blind spots. The recognition camera 61 transmits the captured images to the display controller 11 in real time. The image processing system built into the display controller 11 performs grayscale conversion, noise reduction, contour extraction, and other processing on the images, accurately identifying key parameters such as the welding position, welding area, and surface flatness of the iridium tip. The image processing system compares the identified parameters with preset acceptance standards and automatically determines whether the pen tip welding quality is qualified.

[0050] After the inspection is completed, if the product is determined to be defective: the electric clamp 44 close to the camera inspection component 6 is activated, releasing the defective pen tip body 100. The defective pen tip body 100 falls into the defective bin 7 under its own gravity, completing the collection of defective products; then the electric clamp 44 is reset, ready to clamp the next soldered pen tip. If the product is determined to be qualified: the display controller 11 sends a signal to the feeding assembly 8, the electric push rod 83 is activated, and the feeding chute 82 is moved closer to the detection position, so that one end of the feeding chute 82 is aligned with the qualified pen tip at the detection position and the other end is aligned with the opening of the finished product box 81. The electric clamp 44 close to the camera detection assembly 6 is released, and the qualified pen tip falls into the feeding chute 82 under its own gravity. Through the tilting and guiding action of the feeding chute 82, it slides smoothly into the finished product box 81, completing the automatic feeding of qualified products. After the material is unloaded, the electric push rod 83 retracts, driving the unloading chute 82 to reset, ready for the unloading of the next qualified product; the finished product box 81 and the defective bucket 7 can be removed at any time for the storage of qualified products and the handling of defective products, making operation and maintenance convenient.

[0051] The drive motor 101 rotates continuously at a constant speed, driving the cams to move synchronously, achieving precise linkage of the actions of each component: the pen tip vibratory plate 2 continuously feeds, the pen tip misalignment mechanism 3 continuously positions, the pen tip shifting mechanism 4 continuously clamps and shifts alternately, the welding mechanism 5 continuously completes iridium granule replenishment, welding positioning and welding actions, the camera detection component 6 continuously detects, and the unloading component 8 and defective bin 7 continuously complete unloading and sorting. The entire process requires no manual intervention, achieving high-speed automated continuous production.

[0052] It is worth noting that the above welding and inspection methods have the following beneficial effects: By driving the cams to rotate synchronously through the drive motor 101, the precise linkage of the actions of each component is achieved. There is no need for manual feeding, positioning, inspection, sorting and other operations. This solves the problems of low welding efficiency of iridium tips in existing technologies and the difficulty in achieving high-speed automated production of iridium tips by relying on manual inspection after welding.

[0053] The upper welding assembly 51 is precisely clamped by the pen tip front plate 511 and the conductive moving plate B512, and with the fitting design of the clamping pressure plate 5111, the conductive clamping plate 5121 and the pen tip body 100, it ensures that there is no deviation during pen tip welding; the ejector pin 523 achieves vertical lifting and positioning of the iridium tip through the high-precision cooperation of the slide bar B539 and the lower welding fixing plate 537, while the vent pipe 54 introduces protective gas to isolate air and prevent welding oxidation.

[0054] Using the recognition camera 61 in conjunction with the image processing system in the display controller 11, non-contact online inspection of the soldered pen tip is performed. The system can automatically identify parameters such as the positional deviation of the iridium particle, the welding area, and the surface flatness. This not only eliminates the problems of missed detection and false detection caused by fatigue and strong subjectivity in manual inspection, but also provides real-time data feedback.

[0055] By setting up a defective bin 7 and a feeding component 8, and in conjunction with visual inspection results, qualified products and defective products can be automatically separated. Qualified products slide into the finished product box 81 through the feeding chute 82, while defective products automatically fall into the defective bin 7. No manual sorting is required, which further reduces labor costs.

[0056] By setting up the pen tip misalignment mechanism 3, the pen tip misalignment mechanism 3 achieves the separation and precise positioning of pen tips one by one through the cooperation of the push plate 32 and the slot 33, which solves the problem of material accumulation caused by continuous material discharge from the pen tip vibrating plate 2, and ensures the correct posture of the pen tip at a specific work station, thus providing a guarantee for the stable clamping of the subsequent electric clamp 44.
