Description

Technical Field

[0001] This invention relates to the field of S25 automotive bulb manufacturing technology, and in particular to a wiping device for the solder joints of the bulb head in an S25 bulb aging machine. Background Technology

[0002] Light bulb aging (aging test) is a key quality control process in lighting product manufacturing. It involves testing the electrical performance and operational stability of the bulbs through electrical continuity testing, eliminating substandard products, and ensuring the quality of the bulbs leaving the factory. Utility model patent CN209321910 U discloses a feeding device for a P21 light bulb aging pressurizing machine. This device includes a base, a conveyor track (vibrating feeding component), and a light bulb transfer tray. The transfer tray has several light bulb slots arranged around its circumference. Driven by a stepper motor, the transfer tray rotates intermittently, receiving light bulbs from the conveyor track. A robotic arm then picks up and flips the bulbs, feeding them to the testing station, thus achieving automated light bulb transfer and feeding. This type of transfer tray-type light bulb aging feeding mechanism is widely used in the S25 light bulb aging production line. It relies on a vibrating feeding component to sort and feed the bulbs, which fall into the slots of the light bulb transfer tray. The transfer tray rotates intermittently, transferring the bulbs directly to the feeding station for flipping and feeding.

[0003] However, existing aging and feeding devices of this type can only complete the actions of bulb conveying, transfer, and feeding, and do not have a pre-treatment cleaning structure for the solder joints on the top of the bulb. In actual production, there are the following defects: After the bulb completes the top soldering process, the surface of the solder joint is prone to residual impurities such as solder slag, solder spots, oxide layer, and oil. If the above-mentioned dirt and impurities are not removed in advance, when the bulb enters the aging test, it will cause poor contact between the bulb and the electrodes of the aging equipment, resulting in problems such as abnormal power supply, misjudgment of detection, and wrong rejection of good products. Bulbs with dirty solder joints entering the market will also cause customer quality complaints and damage the brand reputation. Summary of the Invention

[0004] The purpose of this invention is to provide a wiping device for the solder joints of the lamp holder in an S25 bulb aging machine. This device can automatically clean and wipe the solder joints on the top of the lamp holder, remove residual dirt from the solder joints, and solve problems such as poor contact and customer complaints caused by dirty solder joints.

[0005] To achieve the above objectives, the present invention provides the following solution:

The lifting cylinder is located on the lower part of the support, and the piston rod at the lower end of the lifting cylinder is connected to the wool wheel, which is located below the wiping station and is driven to rotate by a rotary motor. When the piston rod of the pressing cylinder moves downward, it can drive the pressing head to press the lamp. When the piston rod of the lifting cylinder moves upward, it can drive the rotating wool wheel upward to wipe the lamp holder.

[0007] Preferably, there are twelve bayonets, and the wiping station includes two bayonets, namely the third bayonet and the fourth bayonet, which are respectively the bayonets after the light bulbs are fed into the light bulb transfer tray.

The upper end of the second slide rod protrudes from the second through hole and is provided with an external thread and is threadedly connected to the second limiting block.

[0010] Preferably, the pressure head is provided in two parts, namely a first pressure head and a second pressure head. The first pressure head corresponds to the third bayonet, and the second pressure head corresponds to the fourth bayonet. The lower end of the first slide rod is threaded to the upper part of the first pressure head, and the lower end of the second slide rod is threaded to the upper part of the second pressure head. Each pressure head has an inner groove at the bottom that matches the light bulb, and each pressure head has a silicone buffer pad at the bottom.

[0011] Preferably, a first spring is sleeved on the outer wall of the first slide rod, and a second spring is sleeved on the outer wall of the second slide rod. The upper end of each spring is located in a linear bearing on the same side, and the lower end of each spring abuts against the upper surface of the pressure head on the same side.

[0012] Preferably, there are two wool wheels, namely a first wool wheel and a second wool wheel.

[0016] The present invention achieves the following beneficial technical effects compared to the prior art:

[0017] The S25 bulb aging machine's lamp head solder joint wiping device provided by this invention uses a downward movement of the piston rod of a pressing cylinder to drive a pressure head to press the bulb from above, limiting its position. A lifting cylinder drives a rotating wool wheel to rise from below the lamp head and contact the solder joint. The rotating wool wheel cleans the solder joint of slag, oxide layer, and oil, effectively removing residual dirt from the lamp head solder joint and solving problems such as poor contact and customer complaints caused by dirty solder joints. The invention's vertically aligned positioning-brushing structure achieves the effect of "first positioning and fixing the bulb, then performing solder joint brushing." Furthermore, the third and fourth clamps are located on one side of the vibrating feeding assembly, allowing the robotic arm mechanism for gripping and flipping the bulb during feeding to be located on the other side. This not only ensures that the mechanisms do not interfere with each other, but also allows for the addition of a lamp head brushing device to the existing aging machine feeding mechanism, while retaining the original base, vibrating feeding assembly, and bulb transfer tray. Only the existing equipment needs to be upgraded, without replacing the entire machine, thus reducing modification costs. Attached Figure Description

Detailed Implementation

[0023] This invention provides a wiping device for the solder joints of the lamp holder in an S25 bulb aging machine, such as... Figures 1-4 As shown, the device includes a base 1, on which a vibrating feeding assembly 2 and a bulb transfer tray 3 are mounted. The vibrating feeding assembly 2 transports the bulbs to the slots 4 of the bulb transfer tray 3. The bulb transfer tray 3 is driven by a cylinder to rotate intermittently to move the bulbs. The conveying of the vibrating feeding assembly 2 and the transfer of the bulb transfer tray 3 are existing technologies and will not be described in detail here. This wiping device also includes a bulb pressing and positioning device and a bulb head brushing device. The bulb pressing and positioning device includes a pressing cylinder 5 and a pressing head. A bracket 7 is mounted on the base 1, and the pressing cylinder 5 is located on the upper part of the bracket 7. The piston rod at the upper end of the pressing cylinder 5 is connected to the pressing head, which is located above the wiping station. In this embodiment, there are twelve slots, and the wiping station includes two slots, namely the third slot 8 and the fourth slot 9 after the bulbs are fed into the bulb transfer tray 3. The lamp holder cleaning device includes a lifting cylinder 10 and a wool wheel. The lifting cylinder 10 is located at the lower part of the bracket 7. The piston rod at the lower end of the lifting cylinder 10 is connected to the wool wheel. The wool wheel is located below the wiping station and is driven to rotate by the rotary motor 6. When the piston rod of the pressing cylinder 5 moves downward, it can drive the pressure head to press the bulb. When the piston rod of the lifting cylinder 10 moves upward, it can drive the rotating wool wheel to move upward to wipe the lamp holder.

[0024] In this invention, the downward movement of the piston rod of the lowering cylinder 5 drives the pressure head to press the bulb from above, limiting the bulb's position. The lifting cylinder 10 drives the rotating wool wheel to rise from below the bulb head and contact the solder joint. The rotating wool wheel cleans the solder joint by wiping away solder slag, oxide layer, and oil stains, thus cleaning residual dirt from the solder joint and solving problems such as poor contact and customer complaints caused by dirty solder joints. The positioning-brushing structure arranged vertically in this invention achieves the effect of "first positioning and fixing the bulb, then performing solder joint brushing" for the bulb. In addition, the third bayonet 8 and the fourth bayonet 9 are located on one side of the vibrating feeding assembly 2, and the robotic arm mechanism for gripping and flipping the bulb during feeding can be set on the other side of the vibrating feeding assembly 2. This not only ensures that the actions of the mechanisms do not interfere with each other, but also adds a bulb head brushing device to the existing feeding mechanism of the aging machine, retaining the main structure of the original base 1, vibrating feeding assembly 2, and bulb transfer tray 3. Only the existing equipment needs to be modified and upgraded, without replacing the entire machine, thus reducing modification costs.

[0025] Specifically, the piston rod of the downward-pressing cylinder 5 is connected to the first connecting plate 11, and the first connecting plate 11 is connected to the second connecting plate 12. The second connecting plate 12 is located above the bulb transfer plate 3. The second connecting plate 12 is provided with a first through hole 13 and a second through hole 14. A first linear bearing 15 is fixedly connected in the first through hole 13, and a second linear bearing 16 is fixedly connected in the second through hole 14. A first sliding rod 17 is slidably connected in the first linear bearing 15, and a second sliding rod 18 is slidably connected in the second linear bearing 16. The upper end of the first sliding rod 17 protrudes from the first through hole 13 and is provided with external threads and is threadedly connected to the first limiting block 19. The upper end of the second sliding rod 18 protrudes from the second through hole 14 and is provided with external threads and is threadedly connected to the second limiting block 20. The pressure head has two parts, namely the first pressure head 21 and the second pressure head 22. The first pressure head 21 corresponds to the third bayonet 8, and the second pressure head 22 corresponds to the fourth bayonet 9. The lower end of the first slide rod 17 is threaded to the upper part of the first pressure head 21, and the lower end of the second slide rod 18 is threaded to the upper part of the second pressure head 22. Each pressure head has an inner groove 23 at the bottom that matches the bulb, which can radially limit the top of the bulb's glass shell and prevent the bulb from moving horizontally. Each pressure head has a silicone buffer pad at the bottom to form a flexible contact and avoid the rigid pressure head directly squeezing and damaging the bulb when pressing down.

[0026] When the piston rod of the pressing cylinder 5 moves downward, it drives the first connecting plate 11, the second connecting plate 12, the two linear bearings, the two sliding rods, and the two pressing heads to move downward, so that the pressing heads press against the bulb. Each sliding rod is slidably engaged with its corresponding linear bearing, allowing the pressing head to move vertically downward to contact and abut against the bulb's glass shell. The upper end of the sliding rod is provided with an external thread and is threadedly connected to a limiting block. The height of the limiting block can be adjusted by screwing the thread, thereby limiting the maximum downward stroke of the sliding rod and indirectly limiting the maximum downward stroke of the pressing head, preventing the pressing head from pressing down too much and crushing the bulb's glass shell.

[0027] A first spring 24 is sleeved on the outer wall of the first slide rod 17, and a second spring 25 is sleeved on the outer wall of the second slide rod 18. The upper end of each spring is located in the linear bearing on the same side, and the lower end of each spring abuts against the upper surface of the pressure head on the same side.

[0028] When the piston rod of the downward-pressing cylinder 5 moves downward, it drives the first connecting plate 11, the second connecting plate 12, the two linear bearings, the two sliding rods, and the two pressure heads to move downward. After the pressure head contacts the bulb's glass shell, the piston rod continues to move downward, driving the second connecting plate 12 to continue moving downward. This causes each linear bearing to move downward along its corresponding sliding rod. At this time, the two springs are compressed, and the spring force flexibly presses the bulb, preventing the cylinder from rigidly pressing it down. This provides overload protection for the bulb and prevents excessive cylinder thrust from crushing the glass shell. When the piston rod of the downward-pressing cylinder 5 moves upward to reset, the spring force assists the pressure head in rebounding and lifting, detaching it from the bulb.

[0029] The system has two wool wheels, designated as a first wool wheel 26 and a second wool wheel 27. The first wool wheel 26 corresponds to the first pressure head 21, and the second wool wheel 27 corresponds to the second pressure head 22. These two wool wheels correspond to the bulb holders at the third and fourth workstations, wiping both bulb holders with each stroke, thus improving wiping efficiency. Specifically, the piston rod of the lifting cylinder 10 is connected to the support plate 28, and the upper surface of the support plate 28 is connected to the first vertical plate 29. A rotating shaft 30 is rotatably connected to the first vertical plate 29, and the two wool wheels are spaced apart on the rotating shaft 30. The rotating shaft 30 is connected to the rotary motor 6 via a coupling 31. When the piston rod of the lifting cylinder 10 moves upward, it drives the support plate 28, the first vertical plate 29, the rotating shaft 30, and the rotary motor 6 to move upward, thereby driving the two wool wheels to move upward to contact and wipe the bulb holders.

[0030] The lower surface of the support plate 28 is connected to the second vertical plate 32, which is connected to the slider 33. The slider 33 is slidably connected to the vertical slide rail 34, which is fixed to the base 1. As the lifting cylinder 10 moves, the support plate 28 simultaneously moves the slider 33 along the slide rail 34, further defining the vertical direction and sharing the radial force on the piston rod of the lifting cylinder 10. This prevents the piston rod from being deformed by radial load due to the reverse lateral force when the wool wheels contact the lamp head. The two wool wheels are made of high-density pure wool material with moderate hardness, effectively cleaning the welding slag, weld spots, oxide layer, and minor burrs on the surface of the welding points on the lamp head, while avoiding damage to the welding points and electrode structure on the lamp head.

[0031] The fixed end of the lifting cylinder 10 is fixed to the bracket 7 via a connecting frame 35. A horizontal plate 36 is provided on the connecting frame 35, and a buffer positioning screw 37 is inserted through one side of the horizontal plate 36. The lower end of the buffer positioning screw 37 abuts against the piston rod of the lifting cylinder 10. This allows the buffer positioning screw 37 to be rotated to finely adjust the limit position, thereby adjusting the contact height between the wool wheel and the welding point on the top of the lamp holder.

[0032] The wiping device for the solder joints of the S25 bulb aging machine provided by this invention, during use, involves a vibrating feeding assembly 2 that sequentially transports the S25 bulbs, while the bulb transfer tray 3 is driven by a drive mechanism to rotate intermittently, with each bulb falling into the slots of the twelve-station bulb transfer tray 3. First, the controller starts the rotary motor 6, which drives the rotating shaft 30 via a coupling 31, causing the first wool wheel 26 and the second wool wheel 27 to rotate at high speed. After the bulbs flow to the third slot 8 and the fourth slot 9, the controller controls the piston rod of the pressing cylinder 5 to extend downwards. The pressing cylinder 5 drives the first connecting plate 11, the second connecting plate 12, two linear bearings, two sliding rods, and two pressing heads downwards. The silicone buffer pad at the bottom of each pressing head contacts the top of the bulb's glass shell. As the piston rod of the pressing cylinder 5 continues to descend, the spring on the outside of the sliding rod is compressed, and the bulb is flexibly pressed against the spring force. Then, the controller controls the piston rod of the lifting cylinder 10 to extend upwards, driving the support plate 28, the first vertical plate 29, the rotating shaft 30, and the two high-speed rotating wool wheels to move upwards as a whole; at the same time, it drives the slider 33 to slide vertically upwards along the vertical slide rail 34. The high-speed rotating wool wheels are in contact with the welding points on the top of the lamp head and the outer circumference of the lamp head, rotating and rubbing to remove welding slag, welding spots, oxide layers, oil and dirt from the surface of the welding points. After maintaining a certain brushing and wiping time, the welding point cleaning is completed. When the brushing and wiping time ends, the piston rod of the lifting cylinder 10 retracts downwards, driving the wool wheels to descend. The wool wheels disengage from the lamp head, and the piston rod of the pressing cylinder 5 retracts upwards to reset. The sliding rod follows upwards, driving the first pressing head 21 and the second pressing head 22 to lift up and leave the bulb, releasing the pressure constraint on the bulb. Then, the pressing and wiping steps are repeated for the next set of bulbs.

[0033] This invention has illustrated its principles and implementation methods using specific examples. The descriptions of these embodiments are merely illustrative of the method and its core ideas; furthermore, those skilled in the art will recognize that modifications may be made to the specific implementation methods and application scope based on the principles of this invention. Therefore, the content of this specification should not be construed as limiting the invention.
