[0042] A laser marking machine 100 proposed by the present invention aims to provide a laser marking machine 100 with high working efficiency. The specific structure of the laser marking machine 100 of the present invention will be described below:

[0043] Referring to Figures 1 to 8 , in an embodiment of the laser marking machine 100 of the present invention, the laser marking machine 100 includes:

[0044] A frame 10, and a machine table 11 is provided on the frame 10;

[0045] A transmission track 20, which is provided on the machine table 11. Along the transmission direction of the transmission track 20, a loading position, a marking position, and an unloading position are sequentially arranged at intervals on the transmission track 20. The transmission track 20 is used to transmit the nameplate to be processed from the loading position to the marking position and transmit the finished nameplate to the unloading position;

[0046] A feeding bin 30, which is provided on the machine table 11 and has a discharge port, and the discharge port is oppositely arranged with the loading position;

[0047] A first material taking mechanism 40, which is provided on the machine table 11 and is used to convey the product from the discharge port to the loading position; and

[0048] A marking device 50, which is provided on the machine table 11. The marking device 50 has a laser emission port, and the laser emission port is oppositely arranged with the marking position and is used to perform laser marking treatment on the nameplate to be processed at the marking position.

[0049] In this embodiment, the frame 10 includes an upper frame 12 and a lower frame 13. A machine table 11 is provided between the upper frame 12 and the lower frame 13. Among them, a control electrical box and an industrial control computer are provided in the lower frame 13, and the industrial control computer is provided with a programmable control system (PLC).

[0050] The laser marking machine 100 mainly realizes the automatic control of structures such as the transmission track 20, the feeding bin 30, the first material taking mechanism 40, the marking device, and the second material taking mechanism 60 through the programming of the PLC program.

[0051] The first material taking mechanism 40 is disposed opposite to the loading position of the transmission track 20, and the second material taking mechanism 60 is disposed opposite to the material taking position of the transmission track 20.

[0052] The laser marking machine further includes a second material taking mechanism 60. The second material taking mechanism 60 is disposed on the machine table 11 and above the transmission track 20, and is used to take out the finished nameplate from the material taking position. The second material taking mechanism 60 includes a fixed plate, a material taking head, a lifting cylinder, a conveying slide rail, and a driving member. The fixed plate is disposed on the tabletop of the machine table 11. The conveying slide rail is disposed on one surface of the fixed plate and extends along the transmission direction of the transmission track 20. The driving member drives the lifting cylinder to be slidably connected to the surface of the conveying slide rail away from the fixed plate. The material taking head is disposed on the lifting part of the lifting cylinder to drive the material taking head to move towards or away from the material taking position of the transmission track 20, so that the material taking head can suck the workpiece at the material taking position. The second material taking mechanism 60 further includes a discharging groove, and the material taking head can suck the finished nameplate at the material taking position into the discharging groove.

[0053] The laser marking machine 100 further includes a signal device. The signal device includes a sensor, an alarm, a camera, and a display screen. Among them, sensors are provided at the loading position, the marking position, and the material taking position of the transmission track 20. The sensor at the loading position senses whether there is incoming material. If there is no material, the display lamp of the alarm will remind the user, and the signal will be fed back in the control system. When incoming material is sensed, the control system controls the first material taking mechanism 40 to work to convey the product from the discharging port to the loading position; the sensor at the marking position senses the incoming material. After sensing the incoming material, the signal is transmitted to the control system, and the marking device is controlled to work. At the same time, the camera can collect the image information of the marking result and send it to the display screen for display, so that the user can observe whether the marking result is good; the sensor at the material taking position senses the incoming material, and the control system controls the second material taking mechanism 60 to work to take out the product from the material taking position.

[0054] Therefore, it can be understood that in the technical solution of the present invention, the laser marking machine 100 sequentially transports the product to the loading position, the marking position and the material taking position through the transmission track 20, wherein the product is transported from the discharge port of the feed bin 30 to the loading position through the first material taking mechanism 40, and then the product is transported to the marking position by the transmission track 20 for marking by the marker, and after the marking is completed, the product is transported to the material taking position by the transmission track 20, thereby completing the automatic loading and unloading process, without manual loading and unloading, and improving the work efficiency. That is, the present invention provides a laser marking machine 100 with high work efficiency.

[0055] Combined with reference Figures 1 to 7 In one embodiment of the laser marking machine 100 of the present invention, the feed bin 30 includes two adjustment plates 31, both of which are convexly arranged on the table of the machine and arranged opposite to each other. A material trough is provided on the surface of one adjustment plate 31 facing the other adjustment plate 31, and the material trough extends along the height direction of the laser marking machine 100. The two material troughs are arranged opposite to each other and form a material storage trough, and the discharge port is arranged at the discharge end of the material storage trough.

[0056] The feed bin 30 further includes a driving mechanism 32 , which is transmission-connected to the two adjustment plates 31 and drives the two adjustment plates 31 to move closer to or away from each other so as to adjust the size of the material storage trough.

[0057] In this embodiment, the two adjustment plates 31 are arranged in linkage, that is, one driving motor can simultaneously drive the two adjustment plates 31 to move closer to each other to reduce the material storage slot, or to move away from each other to expand the material storage slot, thereby reducing the use of driving motors and effectively reducing costs. Of course, in other embodiments of the present invention, in order to improve the flexibility of adjusting the two adjustment plates 31, the two adjustment plates 31 can also be respectively connected to different driving motors.

[0058] It can be understood that in order to improve the versatility of the feed bin 30 to accommodate products of different sizes, a driving mechanism 32 is used to drive the two adjustment plates 31 to move closer to or away from each other to adjust the size of the storage trough.

[0059] Combined with reference Figures 1 to 7 In one embodiment of the laser marking machine 100 of the present invention, the driving mechanism 32 includes a hand wheel 324, a screw rod 321, a first nut 322 and a second nut 323. The screw rod 321 is rotatably disposed on the table of the machine table 10 and extends along the arrangement direction of the two adjustment plates 31. The first nut 322 and the second nut 323 are both sleeved on the screw rod 321, and the two adjustment plates 31 are fixedly connected to the first nut 322 and the second nut 323, respectively.

[0060] The handwheel 324 is drivingly connected to the lead screw 321 to drive the lead screw 321 to rotate relative to the first nut 322 and the second nut 323, so that the first nut 322 and the second nut 323 move towards each other or in opposite directions along the lead screw 321.

[0061] It can be understood that by driving the lead screw 321 to rotate through the handwheel 324, the lead screw 321 can rotate relative to the first nut 322 and the second nut 323. This setting can convert the rotational motion into a linear motion process, so that the driving mechanism 32 can easily achieve the transmission process to drive the two adjusting plates 31 to move linearly relative to each other.

[0062] Of course, in other embodiments of the present invention, a push cylinder can also be used as the driving mechanism 32. The push cylinder includes a fixed part and a telescopic rod. The telescopic rod is fixedly connected to the two adjusting plates 31, and the telescopic rod is slidably connected to the fixed part to drive the two adjusting plates 31 to approach or move away from each other.

[0063] Referring to Figures 1 to 7 , in an embodiment of the laser marking machine 100 of the present invention, each adjusting plate 31 includes a limiting plate 311 and a mounting plate 312. The mounting plate 312 is slidably disposed on the tabletop of the machine table 11 and extends along the transmission direction of the transmission track 20. The limiting plate 311 is disposed on the mounting plate 312 and extends in the direction facing the tabletop of the machine table 10, and the two limiting plates 311 are oppositely disposed. A material groove is provided on the surface of one limiting plate 311 facing the other limiting plate 311.

[0064] In this embodiment, the mounting plate 312 extends along the transmission direction of the transmission track 20, that is, extends in the horizontal direction, and the limiting plate 311 is perpendicular to the mounting plate 312, that is, extends in the vertical direction.

[0065] It can be understood that in order to facilitate adjusting the size of the material storage groove and at the same time facilitate the installation and fixation of the adjusting plate 31, the mounting plate 312 is slidably disposed on the tabletop of the machine table 11, and the limiting plate 311 is disposed on the mounting plate 312 and extends in the direction facing the tabletop of the machine table.

[0066] Referring to Figures 1 to 7 , in an embodiment of the laser marking machine 100 of the present invention, each limiting plate 311 includes a first movable plate 311a, a second movable plate 311b and a connecting plate 311c;

[0067] In a limiting plate 311, a connecting plate 311c is disposed above a mounting plate 312. A first movable plate 311a and a second movable plate 311b are both slidably disposed on two sides of the connecting plate 311c, and both extend toward the direction of the other limiting plate 311 and are oppositely arranged. The sliding directions of the first movable plate 311a and the second movable plate 311b are consistent with the conveying direction of the conveying track 20 so as to approach each other or move away from each other.

[0068] In this embodiment, in a limiting plate 311, a plurality of first mounting grooves and second mounting grooves are formed in the surface of the connecting plate 311c facing the other limiting plate 311. The first movable plate 311a is inserted through the first mounting groove and slides within the first mounting groove. The second movable plate 311b is inserted through the second mounting groove and slides within the second mounting groove.

[0069] The limiting plate 311 further includes a driving cylinder, an adjusting lead screw, a third nut, and a fourth nut. The two ends of the adjusting lead screw are respectively inserted through the first movable plate 311a and the second movable plate 311b. A first connection hole is formed in the surface of the first movable plate 311a facing the second movable plate 311b. A second connection hole is formed in the surface of the second movable plate 311b facing the first movable plate 311a. The third nut is inserted through the first connection hole and fixedly connected to the first connection hole. The fourth nut is inserted through the second connection hole and fixedly connected to the second movable plate 311b. Both the third nut and the fourth nut are sleeved on the adjusting lead screw. The driving cylinder is in transmission connection with the adjusting lead screw to drive the adjusting lead screw to rotate relative to the third nut and the fourth nut, so that the third nut and the fourth nut move toward each other or move in opposite directions along the adjusting lead screw.

[0070] It can be understood that, in order to enable the feeding bin 30 to not only adjust the size of the storage tank in the X-axis direction, but also adjust the size of the storage tank in the Y-axis direction to improve the versatility of the feeding bin 30, the first movable plate 311a and the second movable plate 311b in the limiting plate 311 are made to approach each other or move away from each other to further adjust the size of the storage tank.

[0071] Referring to Figures 1 to 8 , in an embodiment of the laser marking machine 100 of the present invention, the conveying track 20 includes two conveyor belts 21. Each conveyor belt 21 is rotatably disposed on the surface of a mounting plate 312 facing the other mounting plate 312, and the two conveyor belts 21 are oppositely arranged. The limiting plate 311 is disposed higher than the conveyor belts 21.

[0072] In this embodiment, the conveying track 20 further includes a driving assembly. The driving assembly includes a driving motor, a driving wheel, and a driven wheel. The output shaft of the driving motor is rotationally connected to the driving wheel. The driving wheel is in transmission connection with the driven wheel through the conveyor belt 21.

[0073] It can be understood that, for the convenience of product transmission and to facilitate the adjustment of the width of the transmission track 20, each conveyor belt 21 is rotatably arranged on a mounting plate 312 so as to adjust the width of the transmission track 20 as the adjusting plate 31 moves, thereby enabling the transmission track 20 to adapt to workpieces of different sizes.

[0074] With reference to Figures 1 to 8 , in an embodiment of the laser marking machine 100 of the present invention, a plurality of first limiting blocks 211 are arranged on the conveying surface of a conveyor belt 21, and the plurality of first limiting blocks 211 are arranged at intervals along the length direction of the conveyor belt 21. A plurality of second limiting blocks 212 are arranged on the conveying surface of another conveyor belt 21, and the plurality of second limiting blocks 212 are arranged at intervals along the length direction of the other conveyor belt 21. Each first limiting block 211 is arranged opposite to a second limiting block 212.

[0075] It can be understood that, for the convenience of product transmission and to ensure the stability of product transmission on the transmission track 20, a plurality of first limiting blocks 211 are arranged on the conveying surface of a conveyor belt 21, and a plurality of second limiting blocks 212 are arranged on the conveying surface of another conveyor belt 21 to prevent the workpiece from shifting in position during the transmission on the transmission track 20, thereby causing problems such as marking misalignment.

[0076] With reference to Figure 8 , in an embodiment of the laser marking machine 100 of the present invention, each limiting plate 311 further includes a roller 311d. In a limiting plate 311, the roller 311d is rotatably arranged on the surface of the connecting plate 311c facing another limiting plate 311 and is arranged at the discharge port.

[0077] The first material taking mechanism 40 is a first suction cup. The first suction cup is arranged between the two conveyor belts 21 and is arranged below the conveying surface of the conveyor belt 21. The first suction cup is arranged opposite to the discharge port, and the axial direction of the roller 311d is arranged at an angle with the suction direction of the first suction cup.

[0078] In this embodiment, the two rollers 311d in the two limiting plates 311 are arranged parallel and opposite to each other. The rotation direction of one roller 311d is towards the other roller 311d, and the axial directions of the two rollers 311d are perpendicular to the suction direction of the first suction cup, so that the product can be separated from between the two rollers 311d to the transmission track 20 under the action of the first suction cup.

[0079] In a limiting plate 311, a groove is formed on the surface of the connecting plate 311c facing another limiting plate 311. The groove extends along the length direction of the roller 311d, and the roller 311d is rotatably arranged in the groove.

[0080] It can be understood that, in order to better control the products in the feeding bin 30 and facilitate the first suction cup to control the conveyance of only one product to the loading position of the transfer track 20 each time for accurate marking process, a roller 311d is provided at the discharge port of the feeding bin 30. Before the first suction cup works, the products are controlled by the roller 311d so as not to fall. When the first suction cup works, it sucks the product at the bottom of the feeding bin 30, deforms the product to disengage from the control of the roller 311d, and thus the product drops onto the transfer track 20 to complete the automatic loading process.

[0081] Certainly, in other embodiments of the present invention, the first material taking mechanism 40 can also be a manipulator, which conveys the product from the discharge port to the loading position of the transfer track 20 to complete the automatic loading process.

[0082] With reference to Figures 1 to 7 , in an embodiment of the laser marking machine 100 of the present invention, the driving mechanism 33 further includes two sliders 332 and a slide rail 333. The slide rail 333 is provided on the table surface of the machine platform 11 and extends along the arrangement direction of the two adjusting plates 31. The two sliders 332 are both slidably connected to the slide rail 333 and are provided on the surface of the slide rail 333 facing away from the machine platform 11. Each adjusting plate 31 is fixedly connected to the surface of a slider 332 facing away from the slide rail 333, and each adjusting plate 31 is slidably connected to the machine platform 11 through a slider 332 in cooperation with the slide rail 333.

[0083] In this embodiment, multiple slide rails 333 are provided, and the multiple slide rails 333 are arranged at intervals along the length direction of the mounting plate 312. A plurality of sliders 332 are provided, and each slider 332 is slidably connected to the surface of a slide rail 333 facing away from the machine platform 11.

[0084] It can be understood that, in order to improve the movement stability of the two adjusting plates 31 to stably adjust the size of the storage slot and the width of the transfer track 20, each adjusting plate 31 is slidably connected to the machine platform 11 through a slider 332 in cooperation with the slide rail 333.

[0085] With reference to Figure 2 and Figure 3 , in an embodiment of the laser marking machine 100 of the present invention, the laser marking machine 100 further includes an air extraction duct 70. The air extraction duct 70 is provided above the transfer track 20, and the air extraction port of the air extraction duct 70 faces the marking position.

[0086] It can be understood that, when the laser marking head 51 marks the product, impurities such as debris and dust are easily generated. Therefore, in order to improve the marking accuracy of the product and ensure the internal cleanliness of the laser marking machine 100, the air extraction port of the air extraction channel is set to face the marking position of the transfer track 20 to suck away the impurities generated during the marking of the product.

[0087] With reference to Figures 1 to 7 In an embodiment of the laser marking machine 100 of the present invention, the laser marking machine 100 further includes a second suction cup 80, which is arranged above the marking position and faces the marking position.

[0088] It can be understood that when the product is conveyed from the discharge port to the loading position of the transmission track 20 by using the first suction cup, the product is prone to deformation under the suction force. Therefore, in order to improve the marking accuracy and prevent misaligned marking caused by deformed products, the second suction cup 80 is arranged facing the marking position. When the product is conveyed to the marking position, the product at the marking position is first flattened by the second suction cup 80 to ensure the flatness of the product, and then the flattened product is marked to improve the marking accuracy.

[0089] With reference to Figure 2 and Figure 3 In an embodiment of the laser marking machine 100 of the present invention, the marking device includes a height adjustment component 52 and a laser marking head 51. The height adjustment component 52 is arranged on the machine table 10 and is in transmission connection with the laser marking head 51 to adjust the height of the laser marking head 51.

[0090] In this embodiment, the height adjustment component 52 includes a hand crank handle and a transmission member. The hand crank handle is in transmission connection with the transmission member, and the transmission member is in transmission connection with the laser marking head 51. The hand crank handle drives the laser marking head 51 to move towards or away from the transmission track 20 through the transmission member to adjust the height of the laser marking head 51.

[0091] It can be understood that in order to further improve the marking accuracy and accurately mark products with different thicknesses, the height adjustment component 52 is used to adjust the height of the laser marking head 51.

[0092] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
