Description

Technical Field

[0001] This invention relates to the field of capacitor manufacturing, specifically to a capacitor marking device and marking method. Background Technology

[0002] In capacitor manufacturing, laser marking is typically performed on the capacitor surface to indicate product model, specifications, production batch, and other information for subsequent traceability and use. Most existing capacitor marking devices use a conveyor line in conjunction with a laser marker. However, in actual production, dust, debris, and other impurities easily adhere to the capacitor surface. Direct marking can lead to unclear markings, poor adhesion, or even missing marks. Furthermore, some capacitors require marking or subsequent processing on both sides. Existing equipment usually uses manual flipping or adds a separate flipping mechanism, which is not only inefficient but also prone to capacitors falling or shifting position during flipping, affecting production cycle and yield. Additionally, different capacitor sizes have varying diameters, making it difficult for traditional rigid roller conveyors to adaptively adjust, easily causing conveyor jamming or product damage.

[0003] Therefore, it is necessary to provide a capacitor marking device and marking method. Summary of the Invention

[0004] The present invention provides a capacitor marking device and marking method, which effectively solves the problems of difficulty in flipping and low cleanliness before marking in existing capacitor processing.

The drive shaft assembly includes a second ball bearing A mounted on the second housing, a second shaft A fixedly connected to the inner ring of the second ball bearing A, a second pulley A coaxially fixedly mounted on the second shaft A, a second gear A coaxially fixedly mounted on the second shaft A, and a second lower roller fixedly mounted on the second shaft A. The driven shaft assembly includes a second linear guide rail vertically mounted on the second housing, and a sliding... The drive assembly includes a slide plate mounted on the second linear guide rail, a limiting plate mounted on the second housing and located at the upper end of the second linear guide rail, a first elastic element connecting the lower end face of the limiting plate and the upper end face of the slide plate, a second shaft B mounted on the slide plate, a second gear B coaxially fixedly mounted on the second shaft B and meshing with the second gear A, and a second upper roller pressure roller coaxially fixedly mounted on the second shaft B and located above the lower roller pressure roller. The drive assembly includes a second motor mounted on the second housing, a drive wheel mounted on the rotating shaft of the second motor, and a second belt that is connected to the drive wheel, the second pulley A, and the second pulley B for transmission.

[0008] Furthermore, the second upper roller includes a second main shaft B coaxially and fixedly connected to the second shaft B, and second discs B respectively disposed at both ends of the second main shaft B. The second lower roller A includes a second main shaft A coaxially and fixedly connected to the second shaft A, and second discs A respectively disposed at both ends of the second main shaft A. An annular groove is provided on the outer periphery of the second disc B. The annular groove includes a bottom wall and side walls connected to both sides of the bottom wall. The two sides of the second disc A are respectively located between the two side walls.

[0009] Furthermore, the marking mechanism includes a third support mounted on the frame, a laser marking device mounted on the third support, a third CCD camera mounted on the third support, a dust blowing assembly mounted on the frame and located on one side of the conveyor line, and a positioning assembly mounted on the frame.

[0010] Furthermore, the dust blowing assembly includes a fourth housing mounted on the frame, several air blowers arranged along the X-axis on the fourth housing, and a fourth roller pressing assembly mounted on the second housing.

[0011] Furthermore, the positioning assembly includes a mounting base mounted on the frame, a No. 3 linear guide rail vertically mounted on the mounting base, a lifting seat slidably mounted on the No. 3 linear guide rail, a No. 3 cylinder mounted on the mounting base for driving the lifting seat to rise and fall, and an upper limit rod mounted on the lifting seat.

[0012] Furthermore, the flipping mechanism includes a No. 5 housing and a No. 5 support mounted on the frame, a No. 5 motor mounted on the No. 5 support, a rotating frame mounted on the No. 5 motor shaft, a No. 5 conveying track mounted on the rotating frame, and a No. 5 roller pressing assembly mounted on the rotating frame. The No. 5 conveying track includes an inlet and an outlet, and the No. 5 roller pressing assembly is used to press the capacitors at the inlet and outlet.

[0013] Furthermore, the No. 5 roller pressing assembly includes a No. 5 shaft A rotatably mounted on the rotating frame and located at both ends of the No. 5 conveying track; a mounting frame slidably mounted on the rotating frame; springs at both ends abutting against the mounting frame and the rotating frame respectively; two No. 5 shafts B fixedly mounted on the rotating frame and located above the No. 5 shaft A respectively; a No. 5 pulley A and a No. 5 lower pressing roller coaxially fixed on the No. 5 shaft A; a No. 5 upper pressing roller rotatably mounted on the No. 5 shaft B; a No. 6 motor mounted on the rotating frame; a No. 5 drive wheel coaxially fixed on the No. 6 motor shaft; and a No. 5 belt that is drivingly connected to the No. 5 drive wheel and the No. 5 pulley A.

[0014] The capacitor marking method uses the aforementioned capacitor marking device. After the capacitor passes through the dust removal mechanism to remove surface dust, it is conveyed along the conveyor line to the marking mechanism for laser marking. After marking, it is conveyed along the conveyor line to the flipping mechanism, which flips the capacitor 180 degrees.

[0015] Beneficial effects of the invention: 1. By sequentially setting up a dust removal mechanism, a marking mechanism, and a flipping mechanism along the conveyor line, the entire process of dust removal, upper surface marking, and automatic flipping of capacitors is fully automated. This effectively avoids the impact of dust on marking quality, reduces manual intervention, and significantly improves production efficiency and product yield. Simultaneously, the flipping mechanism can flip the capacitors, facilitating double-sided processing.

[0016] 2. The dust removal mechanism adopts a flexible floating No. 2 roller pressing component. The No. 1 elastic element enables the No. 2 upper roller pressing wheel to adaptively press the capacitor, which not only ensures the stable conveying of capacitors of different diameters, but also avoids damage to the capacitors caused by rigid extrusion. At the same time, it works with the exhaust component to form a relatively closed dust removal space, which has a good dust removal effect and stable operation.

[0017] 3. The flipping mechanism is equipped with No. 5 roller pressing components at both the inlet and outlet of the No. 5 conveying track. Utilizing a spring-loaded sliding mounting frame structure, the No. 5 upper roller pressing roller and the No. 5 lower roller pressing roller continuously apply elastic clamping force to both ends of the capacitor during the flipping process. This achieves both active roller feeding of the capacitor and forms a bidirectional physical blockage during flipping, effectively preventing the capacitor from slipping off both ends of the track due to gravity or inertia. The structure is compact and highly reliable.

[0018] 4. The marking mechanism combines a laser marking machine, a No. 3 CCD camera, a dust blowing component, and a positioning component. The positioning component accurately blocks and positions the capacitor, the dust blowing component removes residual dust before and after marking, and the No. 3 CCD camera can be used to inspect the effect after marking, thus improving the overall quality of the product.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] like Figure 1 As shown, the first embodiment provided in this application is a capacitor marking device, including a frame 1, a conveyor line 2 arranged along the X-axis on the frame 1, a dust removal mechanism 3 and a flipping mechanism 4 respectively arranged on the frame 1 and located at both ends of the conveyor line 2, and a marking mechanism 5 arranged on the frame 1 and located between the dust removal mechanism 3 and the flipping mechanism 4. The dust removal mechanism 3 is used to remove dust from the surface of the capacitor, the marking mechanism 5 is used to mark the upper surface of the capacitor, and the flipping mechanism 4 is used to flip the marked capacitor.

[0030] In actual use, the capacitor first passes through the dust removal mechanism 3 to remove surface dust, then enters the marking mechanism 5 along the conveyor line 2 to complete the marking on the upper surface of the capacitor, and finally enters the flipping mechanism 4 along the conveyor line 2 to flip the capacitor for subsequent processes or unloading.

[0031] In the above design, the entire device integrates dust removal, marking and flipping functions, realizing full automation of the capacitor surface treatment process. It effectively ensures the cleanliness of the surface before marking, avoids marking quality defects caused by dust, and provides convenience for processing or unloading the other side of the capacitor through the flipping mechanism 4, significantly improving production efficiency and yield.

[0032] Specifically: such as Figure 2 As shown, the dust removal mechanism 3 includes a first chamber 31 with an inlet 401 and an outlet 402, an exhaust assembly inside the first chamber 31, a second box 32 on one side of the first chamber 31, a feeding track 33 inside the second box 32, and a second roller pressing assembly 34 on the second box 32. The conveyor line 2 passes through the outlet 402 along the inlet 401, and the second roller pressing assembly 34 is used to roll the capacitors on the conveyor line 2.

[0033] In actual operation, the capacitor passes through the feed inlet 401 of the first cavity 31 along the conveyor line 2 and is rolled into the feeding track 33 by the second roller pressing assembly 34. When the capacitor moves in the second track, the dust on the surface of the capacitor on the second track is removed by the suction assembly using negative pressure. As subsequent capacitors continue to enter the feeding track 33 from the feed inlet 401, the products in the feeding track 33 are removed from the feeding track 33 and rolled by another part of the second roller pressing assembly 34 until they flow out of the discharge port 402.

[0034] In the above design, the structural design and specific implementation of the dust removal mechanism 3 ensures the stable transport of the capacitor during the dust removal process by the roller pressing component, preventing the capacitor from shifting due to airflow impact. At the same time, the cavity structure relatively encloses the dust removal area, improving the dust removal effect. Moreover, the structure is compact and works well with the conveyor line 2.

[0035] Specifically: such as Figure 3 and Figure 4As shown, the second roller pressing assembly 34 includes at least one drive shaft assembly 341, a driven shaft assembly 342 corresponding to the drive shaft assembly 341, and a drive assembly 343 for driving the drive shaft assembly 341 to rotate. The drive shaft assembly 341 includes a second ball bearing A mounted on the second housing 32, a second shaft A3411 fixedly connected to the inner ring of the second ball bearing A, a second pulley A3412 coaxially fixedly mounted on the second shaft A3411, a second gear A3413 coaxially fixedly mounted on the second shaft A3411, and a second lower roller 3414 coaxially fixedly mounted on the second shaft A3411. The driven shaft assembly 342 includes a second linear guide rail 3421 vertically mounted on the second housing 32, and a slidingly mounted... The drive assembly 343 includes a slide plate 3422 on the second linear guide rail 3421, a limiting plate 3423 on the second housing 32 and located at the upper end of the second linear guide rail 3421, a first elastic element 3424 connecting the lower end face of the limiting plate 3423 and the upper end face of the slide plate 3422, a second shaft B3425 on the slide plate 3422, a second gear B3426 coaxially fixed on the second shaft B3425 and meshing with the second gear A3413, and a second upper roller 3427 coaxially fixed on the second shaft B3425 and located above the lower roller. The drive assembly 343 includes a second motor on the second housing 32, a drive wheel on the rotating shaft of the second motor, and a second belt that is connected to the drive wheel, the second pulley A3412, and the second pulley B.

[0036] In actual use, the drive assembly 343 drives the drive wheel to rotate via the second motor. With the cooperation of the second pulley A3412 and the second pulley B, the second belt drives the second pulley A3412 and the second pulley B to rotate synchronously. The second pulley A3412 drives the second shaft A3411 and the second lower roller 3414 to rotate. Simultaneously, the second gear A3413 on the second shaft A3411 drives the meshing second gear B3426 to rotate in the opposite direction. This causes the second upper roller 3427 and the second lower roller 3414 on the second shaft B3425 to rotate in opposite directions, so that the upper and lower end faces of the capacitor are rolled by the second upper roller 3427 and the second lower roller 3414 respectively. The second shaft B3425 is slidably mounted on the second linear guide rail 3421 via the slide plate 3422, and is pressed against the limiting plate 3423 by the first elastic element 3424, thereby adapting to the height of the capacitor and applying elastic roller pressure.

[0037] In the above design, the structure and specific implementation of the No. 2 roller pressing assembly 34 achieves an elastic floating driven shaft structure through elastic elements, which can automatically adapt to the thickness changes of capacitors of different diameters, ensuring that the roller pressing wheel and the capacitor surface are always in close contact and the pressure is moderate, effectively conveying the capacitor and avoiding product damage. At the same time, the gear meshing transmission ensures that the upper and lower roller pressing wheels rotate synchronously in opposite directions, and the conveying is smooth and reliable.

[0038] Specifically: the second upper roller 3427 includes a second main shaft B coaxially and fixedly connected to the second shaft B3425, and second disks B respectively disposed at both ends of the second main shaft B; the second lower roller 3414 includes a second main shaft A coaxially and fixedly connected to the second shaft A3411, and second disks A respectively disposed at both ends of the second main shaft A. Figure 4 As shown, an annular groove 3400 is provided on the outer periphery of the second disk B. The annular groove 3400 includes a bottom wall and side walls connected to both sides of the bottom wall. The two sides of the second disk A are respectively located between the two side walls.

[0039] In actual use, when the second upper roller 3427 and the second lower roller 3414 are not pressing the capacitor, the second disc A on both sides of the upper edge of the second lower roller 3414 extending into the annular groove 3400 is located between the two side walls of the annular groove 3400 of the second disc B, so that the belt can be guided to prevent deviation when running on the pulley through this interlocking structure.

[0040] In the above design, the structural design and specific implementation of the second upper roller pressure roller 3427 and the second lower roller pressure roller 3414 can form an effective lateral limit through the second pulley A3412 and the second pulley B, preventing the belt from running off track or derailing during high-speed operation, thus improving the stability and service life of the transmission system. It is applicable to the belt drive arrangement in the compact space of multiple pulleys in this application.

[0041] Specifically: such as Figure 1 As shown, the marking mechanism 5 includes a third support 51 mounted on the frame 1, a laser marking device 52 mounted on the third support 51, a third CCD camera 53 mounted on the third support 51, a dust blowing assembly 54 mounted on the frame 1 and located on one side of the conveyor line 2, and a positioning assembly 55 mounted on the frame 1.

[0042] In actual use, when the capacitor is transported to the marking station by the conveyor line 2, the positioning component 55 accurately positions the capacitor, and the laser marking machine 52 accurately marks the upper surface of the capacitor according to the preset parameters. At the same time, the dust blowing component 54 blows air on the surface of the capacitor before and after marking to remove residual dust.

[0043] In the above design, the structural design and specific implementation of the marking mechanism 5 can not only use the dust blowing component 54 to further ensure the cleanliness of the marking area and improve the marking clarity and adhesion, but also use the No. 3 CCD camera 53 to detect the marking effect.

[0044] Specifically: such as Figure 5As shown, the dust blowing assembly 54 includes a fourth housing 541 mounted on the frame 1, several air blowers 542 arranged along the X-axis on the fourth housing 541, and a fourth roller pressing assembly 543 mounted on the second housing 32.

[0045] In actual use, the No. 4 box 541 serves as the installation base. During marking, several air blowers 542 arranged along the X-axis sequentially blow air to remove dust from the surface of the capacitors on the conveyor line 2. At the same time, the No. 4 roller pressing assembly 543 rolls and conveys or assists in positioning the passing capacitors to ensure stable movement of the capacitors during the dust blowing process.

[0046] In the above design, the structure and specific implementation of the dust blowing component 54, through the arrangement of multiple air blowers 542, achieves thorough cleaning of the marked capacitor, improving the thoroughness of dust removal. The No. 4 roller pressing component 543 ensures the positional stability of the capacitor under the action of airflow, avoids capacitor displacement or flipping due to air blowing, and ensures the positioning accuracy of subsequent marking.

[0047] Specifically: such as Figure 6 As shown, the positioning component 55 includes a mounting base 551 mounted on the frame 1, a third linear guide rail 552 vertically mounted on the mounting base 551, a lifting seat 553 slidably mounted on the third linear guide rail 552, a third cylinder 554 mounted on the mounting base 551 for driving the lifting seat 553 to rise and fall, and an upper limit rod 555 mounted on the lifting seat 553.

[0048] When it is necessary to limit the capacitor for marking, cylinder 554 drives the lifting seat 553 to rise and fall vertically along linear guide rail 552. The limiting rod 555 set on the lifting seat 553 then descends to the corresponding height of the conveyor line 2, blocking the capacitor from the front and achieving precise limiting of the marking position of the capacitor.

[0049] In the above design, the structural design and specific implementation of the positioning component 55 facilitates timely extension of the blocking mechanism when the capacitor reaches the marking station, and quick retraction to make way after marking is completed, without affecting the continuous operation of the conveyor line 2, thus achieving an effective connection between intermittent high-precision positioning and continuous conveying.

[0050] Specifically: such as Figure 7As shown, the flipping mechanism 4 includes a No. 5 housing 41 and a No. 5 support 42 mounted on the frame 1, a No. 5 motor 43 mounted on the No. 5 support 42, a rotating frame 44 mounted on the shaft of the No. 5 motor 43, a No. 5 conveying track 45 mounted on the rotating frame 44, and a No. 5 roller pressing assembly 46 mounted on the rotating frame 44. The No. 5 conveying track 45 includes an inlet 401 and an outlet 402. The No. 5 roller pressing assembly 46 is used to roll the capacitors at the inlet 401 and the outlet 402. The No. 5 housing 41 has clearance holes on opposite sides for the capacitors to avoid entering and exiting.

[0051] In actual use, the No. 5 roller pressing assembly 46 is respectively installed at the feed inlet 401 and discharge outlet 402 of the No. 5 conveying track 45. It elastically presses the capacitors entering and about to be output. After the capacitors enter the No. 5 conveying track 45, the No. 5 motor 43 drives the rotating frame 44 to begin rotating. At this time, both ends of the capacitor are pressed by the No. 5 roller pressing assembly 46. When the No. 5 motor 43 drives the rotating frame 44 to rotate 180 degrees, the No. 5 conveying track 45 rotates synchronously with the rotating frame 44. The No. 5 roller pressing assemblies 46 at the feed inlet 401 and discharge outlet 402 continuously apply roller pressure to the capacitors during the rotation process through elastic clamping. This ensures stable transport of the capacitors within the track and uses the clamping force formed by the elastic clamping to seal the capacitors inside the track, preventing them from slipping off the track due to gravity. After rotation, because both ends of the capacitors are pressed by the No. 5 roller pressing assembly 46, the No. 5 roller pressing assembly 46 drives the capacitors out of the No. 5 conveying track 45.

[0052] In the above design, the structural design and specific implementation of the flipping mechanism 4 are achieved by setting No. 5 roller pressing components 46 at both the feed inlet 401 and the discharge outlet 402 of the flipping mechanism 4. The elastic pressing force of the roller pressing components forms a bidirectional blockage of the capacitor during flipping, which effectively solves the problem of the capacitor falling from both ends of the track due to gravity or inertia during the flipping process. At the same time, the elastic structure can adapt to the thickness of capacitors of different specifications, which not only ensures smooth feeding and discharging before and after flipping, but also ensures safety and reliability during the flipping process, significantly improving the stability and compatibility of the flipping mechanism 4.

[0053] Specifically: such as Figure 8As shown, the No. 5 roller pressing assembly 46 includes a No. 5 shaft A461 rotatably mounted on a rotating frame 44 and located at both ends of the No. 5 conveying track 45, a mounting frame 462 slidably mounted on the rotating frame 44, a spring 463 with its two ends abutting against the mounting frame 462 and the rotating frame 44 respectively, two No. 5 shafts B464 fixedly mounted on the rotating frame 44 and located above the No. 5 shaft A461 respectively, a No. 5 pulley A465 coaxially fixedly mounted on the No. 5 shaft A461, a No. 5 lower roller pressing roller 466, a No. 5 upper roller pressing roller 467 rotatably mounted on the No. 5 shaft B464, a No. 6 motor 468 mounted on the rotating frame 44, a No. 5 drive wheel coaxially fixedly mounted on the shaft of the No. 6 motor 468, and a No. 5 belt that is drivingly connected to the No. 5 drive wheel and the No. 5 pulley A465.

[0054] It should be noted that the position of the lower roller 466 and the upper roller 467 is based on the position of the lower roller 466 being below the upper roller 467. Figure 8 The position of the middle spring 463 differs from the actual assembly drawing. In the actual assembly, spring 463 does not protrude from the upper surface of the mounting bracket. Figure 8 This is to make it easier to intuitively understand the approximate location of spring 463.

[0055] In actual use, motor 468 drives drive wheel 5 to rotate, which in turn drives pulley A465 and shaft A461 to rotate via belt A461. Lower roller 466 on shaft A461 rotates accordingly, while upper roller 467 is rotatably mounted on shaft B464. Mounting bracket 462 is slidably mounted on rotating frame 44 and is provided with elastic force by spring 463, so that upper roller 467 presses against lower roller 466 with variable pressure. When the capacitor enters the feed port 401 or exits from the discharge port 402, the capacitor is clamped between upper roller 467 and lower roller 466. The compression of spring 463 is adaptively adjusted according to the thickness of the capacitor, thus providing a stable conveying force during normal transport. During the tumbling process, continuous elastic clamping forms a physical blockage to prevent the capacitor from falling off the track.

[0056] In the above design, the structure and specific implementation of the No. 5 roller pressing assembly 46 adopts a sliding mounting frame 462 structure loaded by spring 463, which enables the roller pressing assembly to have both active conveying and elastic sealing functions. While realizing the smooth feeding and discharging of capacitors, the continuous pre-tightening force of spring 463 forms a reliable block at both ends of the capacitor during the flipping process. There is no need to set up an additional gate or gripper mechanism, which simplifies the structure and provides a rapid response. The elastic adjustment characteristics of spring 463 enable it to be compatible with capacitors of different sizes within a certain range, which enhances the versatility and operational reliability of the flipping mechanism 4.

[0057] The second embodiment provided in this application is a capacitor marking method. Using the capacitor marking device, after the dust removal mechanism 3 removes the dust from the surface of the capacitor, it is transported along the conveyor line 2 to the marking mechanism 5 for laser marking. After marking, it is transported along the conveyor line 2 to the flipping mechanism 4, and the capacitor is flipped 180 degrees by the flipping mechanism 4.

[0058] The above design enables the capacitor to be cleaned before marking and allows the marked capacitor to be flipped over, improving marking accuracy and the convenience of double-sided operation.

[0059] In further detail, it should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
