Detailed implementation mode

[0010] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0011] Embodiment: As Figures 1-6As shown in the figure, the present invention provides a continuous online marking machine, which includes a machine body housing 1. Inside the machine body housing 1, a conveyor belt 2 is rotatably installed. On one side of the machine body housing 1, a first motor 3 is fixedly installed, and the output end of the first motor 3 is fixedly connected to one end of the driving roller of the conveyor belt 2. On the conveyor belt 2, a plurality of turnover assemblies 4 are rotatably installed at equal intervals. The plurality of turnover assemblies 4 each include a rotating frame 401, and the rotating frame 401 is rotatably installed on the conveyor belt 2. On one side of the conveyor belt 2, a plurality of second motors 402 are fixedly installed at equal intervals, and the output end of the second motor 402 is fixedly connected to one end of the rotating shaft of the corresponding rotating frame 401. Inside the plurality of rotating frames 401, two clamping plates 403 are slidably installed in a mirror image distribution. On one side of the plurality of clamping plates 403, a clamping groove 4031 is provided. At both ends inside the plurality of rotating frames 401, electric push rods 404 are fixedly installed, and the output end of the electric push rod 404 is fixedly connected to the corresponding clamping plate 403. Inside the machine body housing 1, a marking assembly 6 and a cleaning assembly 7 are installed. The workpiece to be marked can be placed in the rotating frame 401. By using the two electric push rods 404 located in the same rotating frame 401 to work synchronously, the two clamping plates 403 are driven to move towards each other to clamp the workpiece, so that both ends of the workpiece are clamped into the clamping grooves 4031 on the clamping plates 403. Then, the first motor 3 is used to drive the conveyor belt 2 to rotate, and the conveyor belt 2 drives the rotating frame 401 to move. When the rotating frame 401 clamping the workpiece moves to directly below the marking assembly 6, the first motor 3 stops working and the rotating frame 401 stops moving. Then, the cleaning assembly 7 is used to clean the side of the workpiece to be marked. Then, the marking assembly 6 is used to mark the workpiece. After one side is marked, the second motor 402 is used to drive the rotating frame 401 and the workpiece to be turned over by 180 degrees to change the surface. Then, the cleaning assembly 7 is used to clean the side of the workpiece to be marked. Then, the marking assembly 6 is used to mark the workpiece. The turnover assembly 4 can be used to turn over and change the surface of the workpiece to be marked, thus achieving the purpose of facilitating double-sided marking of the workpiece, saving time and effort and having high efficiency. When the conveyor belt 2 drives the rotating frame 401 and the workpiece with marking completed to move to below the conveyor belt 2, the two electric push rods 404 located in the same rotating frame 401 work synchronously, driving the two clamping plates 403 to move away from each other to release the clamping of the workpiece, so that the workpiece falls to the inner bottom end of the machine body housing 1. The inner bottom end of the machine body housing 1 is in a slope shape, which is convenient for the workpiece to slide down. And a sponge pad is laid on the slope to prevent the workpiece from being damaged when it falls.

[0012] The marking component 6 includes a first sliding groove 601, which is fixedly installed at the inner top end of the machine body shell 1. A slider 602 is slidably installed in the first sliding groove 601. The bottom end of the slider 602 is detachably installed with a laser marker 603 through bolts. The laser marker 603, also known as the printing head, is a prior art and mainly includes a laser generator, a galvanometer system, and a focusing lens. The laser generator generates a high-energy laser beam. According to different workpiece materials, the laser focal length is adjusted through the focusing lens, and the laser is reflected by the high-speed galvanometer to complete precise marking for marking. A first lead screw 604 is rotatably installed in the first sliding groove 601, and the first lead screw 604 is threadedly inserted into the slider 602. A third motor 605 is fixedly installed on one side of the machine body shell 1, and the output end of the third motor 605 is fixedly connected to one end of the first lead screw 604. According to the marking position on the workpiece, the third motor 605 is used to drive the first lead screw 604 to rotate. The first lead screw 604 drives the slider 602 to slide in the first sliding groove 601, and the slider 602 drives the laser marker 603 to move.

[0013] The cleaning component 7 includes a second sliding groove 701, which is fixedly installed at the inner top end of the machine body shell 1. A sliding plate 702 is slidably installed in the second sliding groove 701. A roller brush 703 is rotatably installed at the bottom end of the sliding plate 702. Flexible long bristles are fixedly arranged on the outer surface of the roller brush 703, and the bristles can contact the surface of the workpiece in the rotating frame 401. The default position of the roller brush 703 is on one side inside the machine body shell 1, which does not interfere with the movement and flipping of the rotating frame 401. A fourth motor 704 is fixedly installed on one side of the bottom end of the sliding plate 702, and the output end of the fourth motor 704 is fixedly connected to one end of the rotating shaft of the roller brush 703. A second lead screw 705 is rotatably installed in the second sliding groove 701, and the second lead screw 705 is threadedly inserted into the top end of the sliding plate 702. A fifth motor 706 is fixedly installed on one side of the machine body shell 1, and the output end of the fifth motor 706 is fixedly connected to one end of the second lead screw 705. The fifth motor 706 can be used to drive the second lead screw 705 to rotate. The second lead screw 705 drives the sliding plate 702 to move along the second sliding groove 701. The sliding plate 702 drives the roller brush 703 to move from one end of the rotating frame 401 to the other end. The fourth motor 704 is used to drive the roller brush 703 to rotate, cleaning the dust and other impurities on the surface of the workpiece, which is convenient for subsequent marking.

[0014] An inspection opening 5 is provided on one side of the machine body housing 1. A door panel 9 is hingedly installed in the inspection opening 5. By providing the inspection opening 5, it is convenient to inspect and replace the components inside the machine body housing 1. A support plate 8 is fixedly installed inside the machine body housing 1, and the upper surface of the support plate 8 is in contact with the inner surface of the conveyor belt 2. Since the conveyor belt 2 is mostly flexible, the support plate 8 can support the upper half of the conveyor belt 2 to prevent the rotating frame 401 and the workpiece from sinking when the cleaning assembly 7 cleans the workpiece, causing the roller brush 703 to disengage from the workpiece and resulting in incomplete cleaning.

[0015] Working principle: When the present invention is in use, first place the workpiece to be marked in the rotating frame 401. Utilize the two electric push rods 404 located in the same rotating frame 401 to work synchronously, driving the two clamping plates 403 to move towards each other to clamp the workpiece, so that both ends of the workpiece are clamped into the clamping grooves 4031 on the clamping plates 403. Then, utilize the first motor 3 to drive the conveyor belt 2 to rotate, and the conveyor belt 2 drives the rotating frame 401 to move. When the rotating frame 401 clamping the workpiece moves to directly below the laser marker 603, the first motor 3 stops working and the rotating frame 401 stops moving. Then, utilize the fifth motor 706 to drive the second lead screw 705 to rotate, and the second lead screw 705 drives the sliding plate 702 to move along the second chute 701. The sliding plate 702 drives the roller brush 703 to move from one end of the rotating frame 401 to the other end. Utilize the fourth motor 704 to drive the roller brush 703 to rotate, cleaning the dust and other impurities on the surface of the workpiece, facilitating subsequent marking. Then, according to the marking position on the workpiece, utilize the third motor 605 to drive the first lead screw 604 to rotate, and the first lead screw 604 drives the slider 602 to slide in the first chute 601. The slider 602 drives the laser marker 603 to move to the specified position, and utilize the laser marker 603 to perform laser marking on the workpiece. After one side is marked, utilize the second motor 402 to drive the rotating frame 401 and the workpiece to flip 180 degrees to change the surface. Then, utilize the cleaning assembly 7 to clean the side of the workpiece to be marked, and then utilize the marking assembly 6 to mark the other side of the workpiece. After the marking is completed, utilize the first motor 3 to drive the conveyor belt 2 to continue rotating. When the conveyor belt 2 drives the rotating frame 401 and the marked workpiece to move below the conveyor belt 2, the two electric push rods 404 located in the same rotating frame 401 work synchronously, driving the two clamping plates 403 to move away from each other to release the clamping of the workpiece, causing the workpiece to fall to the inner bottom end of the machine body housing 1. The inner bottom end of the machine body housing 1 is in a slope shape, facilitating the sliding of the workpiece; (It should be noted that the electrical components in this device are all linearly connected to an external power supply. This device also includes a control system, a positioning sensor, etc. The control system mainly includes a PLC (programmable logic controller), a drive module, and a communication interface. The PLC (programmable logic controller) is responsible for receiving instructions from the upper computer and coordinating the work of each component; the drive module is used to control the actions of actuators such as the print head and the motor; the communication interface supports Ethernet, RS-485, Wi-Fi, etc., and is linked with other devices on the production line (such as sensors, MES system); the positioning sensors are installed on both sides of the marking component 6 inside the body shell 1, and are used to detect the product position and cooperate with the control system to trigger the control of the print head, the motor, etc. to work, so as to achieve precise marking. The motors in this device are all servo motors and have a self-locking function).
