With the continuous advancement of automation technology, efficient and accurate lifting, positioning, and automatic marking of workpieces on conveyor lines have become key requirements for improving production efficiency and product quality. Traditional production methods often rely on manual operation for pallet positioning and workpiece marking, which is not only inefficient but also difficult to ensure accuracy. Manual positioning is prone to errors, resulting in inaccurate marking positions, affecting the appearance and quality of the product. Furthermore, manual operation is labor-intensive and costly, making it difficult to meet the needs of large-scale production. To address these issues, simple mechanical positioning and marking equipment have been applied to production.
[0003] The existing technology has the following problems in actual use: there are many types of positioning mechanisms for pallets on conveyor lines, and the most commonly used ones are to directly use blocking cylinders to block the movement of pallets on the conveyor line. However, the pallet of this positioning mechanism is not separated from the line body, which will cause the pallet and the conveyor line chain to be in a friction state. During use, the pallet shakes slightly, and the pallet support plate and chain are worn out after long-term use. Secondly, the marking machine cannot be adjusted automatically, so a conveyor line lifting and positioning automatic marking equipment is needed to solve the above problems. Utility Model Content

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.
[0022] The specific embodiments of the present utility model are described below with reference to the accompanying drawings. Specific embodiment one:
[0024] Reference Figure 1-4 A jacking and positioning automatic marking equipment on a conveyor line includes a transmission line 1, a welding frame 2, a pallet jacking and positioning mechanism 3, a workpiece pallet 4, a smoke purifier 5 and an automatic marking mechanism 6. The transmission line 1 is installed on the top of the welding frame 2, the workpiece pallet 4 is installed in the middle of the top of the welding frame 2, the workpiece is placed on the top of the workpiece pallet 4, and the smoke purifier 5 is placed in the middle of the back of the welding frame 2.
[0025] Pallet support rods 10 are passed through both sides of the top of the workpiece pallet 4, and a pallet positioning pin 11 is bolted to one side of the top of the workpiece pallet 4. Both sides of the bottom of the workpiece pallet 4 are connected with a jacking guide shaft 12. A pallet blocking cylinder 7 is installed in the middle of the bottom end of the workpiece pallet 4, and a jacking cylinder 9 is installed on one side of the top of the welding skeleton 2. The front of the jacking cylinder 9 is electrically connected to the pallet in place proximity switch 8. The pallet jacking and positioning mechanism 3 includes a pallet blocking cylinder 7, a pallet in place proximity switch 8, a lifting cylinder 9, a pallet support rod 10, a pallet positioning pin 11 and a lifting guide shaft 12. The transmission line 1 serves as a carrier for the movement of the workpiece pallet 4, so that the workpiece pallet 4 can flow between the various workstations. The welding skeleton 2 serves as the main frame of the equipment, which is used to support and connect the conveyor line body and install various functional components.
[0026] A marking machine frame 13 is installed on the back side of the top of the welding frame 2, close to the side of the smoke purifier 5. The bottom end of the marking machine frame 13 is transmission-connected to a lifting servo motor 16. The front of the marking machine frame 13 is slidingly connected to a lifting block 17. The front of the lifting block 17 is connected to a marking machine head 14. The side of the marking machine head 14 is electrically connected to a laser rangefinder 15. The smoke purifier 5 is mainly a kind of automatic vacuum cleaner, which is used to collect smoke and dust generated when the marking machine is working to keep the product clean and tidy.
[0027] The automatic marking mechanism 6 is composed of a marking machine frame 13 , a marking machine head 14 , a laser rangefinder 15 , a lifting servo motor 16 and a lifting block 17 .
[0028] It should be noted that the lifting of the lifting cylinders 9 on both sides must be synchronized, and the air inlet and outlet speeds of the two cylinders must be as consistent as possible to avoid asynchronous lifting of the lifting mechanism and damage to the guide shaft and linear bearings.
[0029] The automatic marking mechanism 6 needs to return to the highest origin to complete the action. If the mechanism is not at the origin, the workpiece pallet 4 with the workpiece cannot be released to this marking station to avoid the marking machine head 14 being too low and the workpiece pallet 4 with the workpiece colliding with the marking machine when moving to this station. Specific embodiment two:
[0031] Reference Figure 1-4After the equipment is started, the conveyor line 1 begins operating under the motor's drive. At this point, the pallet blocking cylinder 7 in the pallet lifting and positioning mechanism 3 is retracted, the lifting cylinder 9 is in its initial position, and the pallet in-position proximity switch 8 is on standby. The marking machine head 14 in the automatic marking mechanism 6 is at its initial height, and the laser rangefinder 15 is performing a self-test and preparing to measure the working distance. The fume extractor 5 is on, ready to collect fume and dust generated during marking. A worker places the workpiece pallet 4 loaded with a workpiece on the conveyor line 1. The non-slip texture on the conveyor line 1 creates sufficient friction with the workpiece pallet 4, driving the workpiece pallet 4 toward the interior of the equipment. When the workpiece pallet 4 reaches the designated position, the pallet in-position proximity switch 8 is triggered. This signal causes the conveyor line 1 to stop operating. At this point, the pallet blocking cylinder 7 extends, preventing the workpiece pallet 4 from moving further. Subsequently, the lifting cylinder 9 begins operating, smoothly lifting the workpiece pallet 4 via the pallet support rod 10. During the lifting process, the lifting guide shaft 12 ensures smooth and vertical lifting. When the workpiece pallet 4 rises to a certain height, the pallet positioning pin 11 is inserted into the positioning hole of the workpiece pallet 4 to achieve precise positioning of the workpiece pallet 4. At the same time as the workpiece pallet 4 is lifted and positioned, the automatic marking mechanism 6 starts working. The laser rangefinder 15 measures the distance between the marking machine head 14 and the workpiece and transmits the data to the control system. Based on the measurement results, the control system adjusts the height of the marking machine head 14 through the lifting servo motor 16 so that it reaches the optimal marking position. When the marking machine head 14 is adjusted to the appropriate position, it starts marking the workpiece. During the marking process, the marking machine frame 13 provides stable support for the marking machine head 14. At the same time, the smoke purifier 5 continues to work, collecting the smoke and dust generated by marking to keep the product clean and tidy. After marking is completed, the lifting cylinder 9 retracts and the workpiece pallet 4 descends under the action of gravity. The pallet positioning pin 11 is pulled out of the positioning hole, and the pallet blocking cylinder 7 also retracts. The conveyor line 1 is started again and the workpiece pallet 4 that has been marked is transported to the next station. The equipment repeats the above working process and continuously performs lifting, positioning and automatic marking operations on the workpiece on the conveyor line.
[0032] In summary:
[0033] 1. In this equipment, a marking machine frame 13 is installed on the back side of the top of the welding skeleton 2 near the side of the smoke purifier 5. The bottom end of the marking machine frame 13 is transmission-connected to a lifting servo motor 16. The front of the marking machine frame 13 is slidingly connected to a lifting block 17. The front of the lifting block 17 is connected to the marking machine head 14. The side of the marking machine head 14 is electrically connected to a laser rangefinder 15. The smoke purifier 5 is mainly a kind of automatic vacuum cleaner, which is used to collect smoke and dust generated when the marking machine is working to keep the product clean and tidy. The automatic marking mechanism 6 is composed of a marking machine frame 13, a marking machine head 14, a laser rangefinder 15, a lifting servo motor 16 and a lifting block 17. It should be noted that the lifting of the lifting cylinders 9 on both sides must be synchronized, and the air inlet and outlet speeds of the two cylinders must be as consistent as possible to avoid asynchronous lifting of the lifting mechanism and damage to the guide shaft and linear bearings.
[0034] 2. After the equipment is started, the conveyor line 1 begins operating under the drive of the motor. At this point, the pallet blocking cylinder 7 in the pallet lifting and positioning mechanism 3 is retracted, the lifting cylinder 9 is in its initial position, and the pallet in-position proximity switch 8 is on standby. The marking machine head 14 in the automatic marking mechanism 6 is at its initial height, and the laser rangefinder 15 is performing a self-test and preparing to measure the working distance. The fume extractor 5 is on, ready to collect fume and dust generated during marking. A worker places a workpiece pallet 4 loaded with a workpiece on the conveyor line 1. The non-slip texture on the conveyor line 1 creates sufficient friction with the workpiece pallet 4, driving the workpiece pallet 4 toward the interior of the equipment. When the workpiece pallet 4 reaches the designated position, the pallet in-position proximity switch 8 is triggered. This triggers the pallet in-position proximity switch 8, causing the conveyor line 1 to stop operating. At this point, the pallet blocking cylinder 7 extends, preventing the workpiece pallet 4 from moving further. Subsequently, the lifting cylinder 9 activates, smoothly lifting the workpiece pallet 4 via the pallet support rods 10.
