Description

Technical Field

[0001] This utility model relates to the field of flywheel marking technology, and in particular to a device that can automatically mark multiple marks on flywheel assemblies on a conveyor line. Background Technology

[0002] The flywheel assembly is a crucial component of a car engine, mounted behind the crankshaft. Its outer ring gear engages with the starter motor to start the engine. To ensure traceability of all parts, engine manufacturers require that each part be marked with a barcode or QR code containing production information. This allows for quick identification of the part during assembly, establishing a permanent engine record and providing information for future engine maintenance. Therefore, the identifiability of the markings on components is of paramount importance.

[0003] The current common method for marking flywheel assemblies is to use laser marking machines to print QR codes. These machines are currently used offline from the production conveyor line. After the product is conveyed to its designated position, it is manually stopped. Due to the lack of precise positioning, the product is pushed to its approximate location before the marking machine is restarted for marking. This lack of precise positioning leads to inaccurate marking positions and ghosting, resulting in substandard marking quality. Furthermore, when marking multiple marks is required, multiple machines and multiple personnel are needed, resulting in low marking efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to address the above-mentioned shortcomings of the prior art by providing a device that can automatically mark multiple marks on a flywheel assembly on a conveyor line. This device can mark multiple flywheel assemblies at the same station, effectively improving the marking speed and marking quality. It has the characteristics of wide applicability and strong practicality.

[0005] The technical solution adopted by this utility model is: a device that can automatically mark multiple marks on a flywheel assembly on a conveyor line, including a base, a connecting plate on the base, a rotating device for rotating the flywheel assembly on the connecting plate, a lifting conveyor line for conveying the flywheel assembly above the rotating device, a clearance groove in the middle of the lifting conveyor line, the output end of the rotating device being inserted into the clearance groove, multiple lifting cylinders between the bottom of the lifting conveyor line and the base, multiple guide components between the lifting conveyor line and the base, a centering component for positioning the flywheel assembly above the lifting conveyor line, and a marking machine for laser marking on one side of the base.

[0006] As a further improvement, the rotating device includes a CNC indexing head, a connecting sleeve, a base plate, and a mandrel. The CNC indexing head is mounted on a connecting plate. One end of the connecting sleeve is mounted on the rotating end of the CNC indexing head, and the other end of the connecting sleeve is connected to the base plate. The mandrel is arranged in the middle of the base plate. The base plate is provided with a positioning pin that matches the hole position of the flywheel assembly. The base plate is arranged below the clearance groove.

[0007] Furthermore, the lifting conveyor line includes a support base, a drive motor, and two conveyor roller groups. The two conveyor roller groups are symmetrically arranged on the support base. The drive motor is installed on one side of the support base, and the output end of the drive motor is connected to one of the conveyor roller groups.

[0008] Furthermore, the guide assembly includes a slide rod and a guide sleeve. Multiple slide rods are provided around the bottom of the support base. The guide sleeve is installed on the base, and the slide rod is movably inserted into the guide sleeve.

[0009] Furthermore, the centering component includes a mounting frame, a double-rod cylinder, a vertical plate, a connecting beam, and positioning columns. The mounting frame is installed on the lifting conveyor line, the double-rod cylinder is installed at the bottom of the mounting frame, and vertical plates are provided on both output ends of the double-rod cylinder. A connecting beam is provided on the vertical plate, and positioning columns are provided at both ends of the connecting beam.

[0010] Furthermore, the dual-rod cylinder is provided with guide rods on both sides, and the guide rods are movably inserted into the upright plate.

[0011] Furthermore, the lifting conveyor line is equipped with a photoelectric sensor, which is electrically connected to an external controller.

[0012] Beneficial effects Compared with the prior art, this utility model has the following advantages: This invention relates to a device that automatically marks multiple tags on a flywheel assembly on a conveyor line. Under the action of a lifting cylinder, the lifting conveyor line is raised to the same height as the previous process's conveyor line. The flywheel assembly is fed into the lifting conveyor line from the previous process. After the lifting conveyor line brings the flywheel assembly to the marking position, the flywheel assembly triggers a photoelectric sensor on the lifting conveyor line. The photoelectric sensor generates a signal output to the controller, which controls the centering component to operate. A double-rod cylinder pulls the connecting beam through a vertical plate, causing the positioning columns at both ends of the connecting beam to retract and clamp the flywheel assembly, thus centering it. After the component centers and clamps the flywheel assembly, its magnetic sensor sends a signal to the solenoid valve controlling the lifting cylinder. The solenoid valve then commands the lifting cylinder to descend, causing the flywheel assembly to drop so that its center hole inserts into the mandrel of the centering component and its bottom pin hole inserts into the positioning pin, achieving precise positioning on the base plate. The flywheel assembly then disengages from the lifting conveyor line. Once the lifting conveyor line has descended to its designated position, the magnetic sensor on the lifting cylinder supporting its movement sends a signal to release the clamping mechanism from the centering component. After the centering component releases its clamping mechanism, the flywheel assembly... The magnetic sensor on the rotating device sends a signal to the CNC indexing head, which then rotates at a pre-set angle. Once the indexing head reaches its designated position, it sends a signal to the marking machine to apply the first mark. After the first mark is applied, the marking machine sends a feedback signal back to the indexing head, which then rotates again to apply another mark. This process continues until all marks are applied, allowing for 360° marking. Once all marks are printed, the marking machine sends a signal to the lifting cylinder to raise the conveyor line to the same height as the previous conveyor line. After the lifting conveyor line is raised to the same height as the previous conveyor line, the lifting cylinder outputs a signal to the drive motor to start the conveyor line and output the flywheel assembly. This patent has a CNC indexing head set in the tooling first. The marking is performed by linking the self-designed PLC with the marking machine. That is, after marking each mark, the indexing head rotates an adjustable angle to mark the next mark, and so on until the process is completed. The whole process realizes unmanned automatic marking, which effectively improves the marking efficiency. The centering component and the rotating device are used for precise positioning, which effectively improves the marking quality. It has the characteristics of strong practicality and wide applicability. Attached Figure Description

Detailed Implementation

[0015] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0016] See Figure 1-5As shown, this utility model discloses a device for automatically marking multiple marks on a flywheel assembly on a conveyor line. It includes a base 1, a connecting plate 8 on the base 1, a rotating device 2 for rotating the flywheel assembly 9 on the connecting plate 8, a lifting conveyor line 3 for conveying the flywheel assembly 9 above the rotating device 2, a clearance groove 6 in the middle of the lifting conveyor line 3, the output end of the rotating device 2 being inserted into the clearance groove 6, multiple lifting cylinders 7 between the bottom of the lifting conveyor line 3 and the base 1, multiple guide components 4 between the lifting conveyor line 3 and the base 1, a centering component 5 for positioning the flywheel assembly 9 above the lifting conveyor line 3, and a laser marking machine 10 on one side of the base 1. Under the action of the lifting cylinders 7, the lifting conveyor line 3 is raised to the level of the base 1. At the same height as the previous process's conveyor line, the flywheel assembly 9 is transported from the previous process into the lifting conveyor line 3. After the lifting conveyor line 3 moves the flywheel assembly 9 to the marking position, the flywheel assembly 9 triggers the photoelectric sensor 13 on the lifting conveyor line 3. The photoelectric sensor 13 generates a signal output to the controller, which controls the centering component 5 to work. The double-rod cylinder 54 pulls the connecting beam 53 through the upright plate 52. The positioning columns 55 at both ends of the connecting beam 53 on both sides retract and clamp the flywheel assembly 9. After the centering component 5 centers and clamps the flywheel assembly 9, the magnetic sensor on it sends a signal to the solenoid valve that controls the lifting cylinder 7. The solenoid valve sends a command to control the lifting cylinder 7 to descend, thereby causing the flywheel assembly 9 to descend and its center hole to insert into the core of the centering component 5. The pin holes on the bottom surface of shaft 21 and flywheel assembly 9 are inserted into positioning pin 11, allowing it to be precisely positioned on base plate 22. Flywheel assembly 9 disengages from lifting conveyor line 3. After lifting conveyor line 3 descends to its designated position, the magnetic sensor on lifting cylinder 7, which supports its lifting, sends a signal to release clamping onto centering assembly 5. When centering assembly 5 releases clamping, its magnetic sensor sends a signal to output to CNC indexing head 24 of rotating device 2. CNC indexing head 24 of rotating device 2 rotates at a pre-set angle. After CNC indexing head 24 of rotating device 2 reaches its designated angle, it outputs a signal to marking machine 10 to mark the first mark. After the first mark is marked, marking machine 10 sends a feedback signal to CNC indexing head 24 of rotating device 2, indicating that the indexing head has rotated to the designated angle. The marking machine 10 then marks the markings, and so on, marking can be performed in 360°. After all the markings are printed, the marking machine 10 outputs a signal to the lifting cylinder 7 to raise the lifting conveyor line 3 to the same height as the previous conveyor line. After the lifting conveyor line 3 is raised to the same height as the previous conveyor line, the lifting cylinder 7 outputs a signal to the drive motor to start the conveyor line and output the flywheel assembly 9. In this patent, a CNC indexing head is first set in the tooling, and the marking is performed in conjunction with the marking machine through a self-designed PLC. That is, after each marking is printed, the indexing head rotates an adjustable angle to print the next marking, and so on until the process is completed. The whole process realizes unmanned automatic marking, which effectively improves the marking efficiency. The centering component and the rotating device are used for precise positioning, which effectively improves the marking quality.

[0017] Specifically, the rotating device 2 includes a CNC indexing head 24, a connecting sleeve 23, a base plate 22, and a spindle 21. The CNC indexing head 24 is mounted on the connecting plate 8.

The spindle 21 is arranged in the middle of the base plate 22. The base plate 22 is provided with a positioning pin 11 that matches the hole position of the flywheel assembly 9. The base plate 22 is arranged below the clearance groove 6. The spindle 21 centers the flywheel assembly 9. With the cooperation of the positioning pin 11, the flywheel assembly 9 is rotated. By using the rotation of the CNC indexing head 24, the flywheel assembly 9 can be marked multiple times, effectively improving the marking efficiency. If the positioning pin 11 cannot be smoothly inserted into the hole position during the descent process, manual intervention is required, which will not be explained in detail here.

[0018] Preferably, the lifting conveyor line 3 includes a support base 33, a drive motor 31, and two conveyor roller groups 32. The two conveyor roller groups 32 are symmetrically arranged on the support base 33. The drive motor 31 is installed on one side of the support base 33, and the output end of the drive motor 31 is connected to one of the conveyor roller groups 32. The drive motor 31 drives the conveyor roller group 32 to convey the flywheel assembly 9. The clearance groove 6 between the two conveyor roller groups 32 allows the spindle 21 and the base plate 22 of the rotating device 2 to extend out from there, thereby positioning and rotating the flywheel assembly 9.

[0019] Furthermore, the guide assembly 4 includes a slide rod 42 and a guide sleeve 41. Multiple slide rods 42 are provided around the bottom of the support base 33. The guide sleeve 41 is installed on the base 1. The slide rods 42 are movably inserted into the guide sleeve 41. The slide rods 42 play a guiding role, making the lifting and lowering of the lifting conveyor line 3 more stable.

[0020] Furthermore, the centering component 5 includes a mounting frame 51, a double-rod cylinder 54, a vertical plate 52, a connecting beam 53, and positioning posts 55.

The double-rod cylinder 54 pulls the connecting beams 53 through the vertical plates 52, and the positioning posts 55 at both ends of the connecting beams 53 on both sides retract and clamp the flywheel assembly 9, which plays a positioning role for the flywheel assembly 9, so that the center hole of the flywheel assembly 9 can be smoothly inserted into the spindle 21.

[0021] Furthermore, guide rods 12 are provided on both sides of the double-rod cylinder 54. The guide rods 12 are movably inserted into the vertical plate 52. The guide rods 12 play a guiding role, making the operation of the double-rod cylinder 54 more stable.

[0022] Furthermore, a photoelectric sensor 13 is provided on the lifting conveyor line 3. The photoelectric sensor 13 is electrically connected to an external controller. The photoelectric sensor 13 is used to detect whether the flywheel assembly 9 is in place, so as to position the flywheel assembly 9.
