[0029] Example 1

[0030] The present embodiment provides a laser marking device to solve the problems in the related art of slow marking speed, low efficiency, and easy damage or contamination of fixture consumables caused by marking.

[0031] like Figure 1 As shown, a laser marking device includes: a frame 100, a laser 200 and a bearing assembly 300. The laser 200 is mounted on the frame 100. The bearing assembly 300 includes a support truss 310, a fixture platform 330, and a fixture pressure plate 320. The support truss 310 includes a sliding portion and a rotating portion, the sliding portion can be slidably arranged on the frame 100, and the rotating portion can rotate relative to the sliding portion. The fixture platform 330 can be telescopically arranged on the rotating portion, the fixture pressure plate 320 can be slidably mounted on the rotating portion in a direction close to or away from the fixture platform 330, and the fixture pressure plate 320 is arranged parallel to the fixture platform 330; the fixture pressure plate 320 is located on the side of the support truss 310 facing the laser 200.

[0032] Specifically, when using the laser marking device of this embodiment, the jig carrier 330 is controlled to extend in a direction away from the frame 100, and the jig consumable 400 to be marked is placed on the jig carrier 330. After placement, the jig carrier 330 is retracted to a suitable position, and then the jig pressing plate 320 is controlled to slide in a direction close to the jig carrier 330 until the jig pressing plate 320 contacts the jig consumable 400 to fix the jig consumable 400. After fixation, the sliding part of the support truss 310 is controlled to move to change the distance between the laser 200 and the jig consumable 400 so that the laser 200 can be focused. After focusing, the laser 200 is started to laser mark the jig consumable 400.

[0033] After the jig consumable 400 on the jig carrier 330 is laser marked, the sliding part is controlled to move to a suitable position to reserve a rotation space for the rotating part, and then the rotating part is controlled to rotate until the other side of the jig consumable 400 is aligned with the laser 200. The sliding part is controlled to move again to refocus, and after focusing is completed, the other side of the jig consumable 400 can be laser marked.

[0034] The laser marking device of this embodiment does not need to mark the jig consumables 400 one by one manually when marking the jig consumables 400. Through the laser 200, multiple jig consumables 400 can be marked at the same time, thereby improving the efficiency of the marking operation. In addition, the laser 200 used in this embodiment to mark the jig consumables 400 can prevent the jig consumables 400 from being contaminated by chemical markers. Compared with engraving with a knife, the use of laser to mark the outer packaging of the jig consumables 400 will not cause damage to the outer packaging, nor will it produce outer packaging debris. There is no need to worry about the outer packaging of the jig consumables 400 being damaged or contaminated by debris, making this embodiment efficient and reliable, highly safe, and highly practical.

[0035] The laser marking process is called the "photo-erosion" effect. That is, the laser with high load energy can break the chemical bonds in the material or the surrounding medium, causing the material to be destroyed by a non-thermal process, and the inner layer of the material and the area near the processing area do not produce heating or thermal deformation. The laser-marked material processing area has smooth edges and extremely low carbonization to achieve the purpose of laser marking. It can be understood that in this embodiment, through the precise control of the laser energy output, the laser output by the laser 200 can be adapted to a variety of different materials of fixture consumables 400, thereby improving the practicality of this embodiment.

[0036] In one embodiment, the direction in which the jig carrier 330 is extended and retracted is perpendicular to the direction in which the jig platen 320 slides. That is, when the jig carrier 330 needs to be extended and retracted, it can be extended and retracted in the horizontal direction, extending to facilitate the operator to place the jig consumables 400, and retracting to facilitate the jig platen 320 to fix the jig consumables 400. When the jig platen 320 slides, it can slide in the vertical direction, which is convenient for assisting the jig carrier 330 to operate normally and improves the rationality of the structure of this embodiment.

[0037] In one embodiment, illustratively, a horizontal slide rail is provided on the rotating part of the support truss 310, and the jig carrier 330 can be slidably installed in the slide rail. When it is necessary to place a jig on the jig carrier 330, the jig carrier 330 is controlled to slide along the slide rail and extend away from the frame 100 to facilitate the operator to operate. After placement, the jig carrier 330 is controlled to return to the appropriate position and subsequent operations can be carried out.

[0038] In one embodiment, for example, Figure 1 As shown, a first motor 510 is provided on the support truss 310, and the first motor 510 is fixedly provided on the sliding part, and the first motor 510 can drive the rotating part to rotate. In this way, when the jig consumables 400 on the jig carrier 330 are laser marked, the jig carrier 330 can be controlled to rotate by the first motor 510, so as to ensure a stable and smooth rotation process, prevent the jig consumables 400 from falling, improve the reliability of this embodiment, and make this embodiment easy to use.

[0039] When using this embodiment, the jig consumable 400 is placed on the jig carrier 330 and pressed by the jig pressing plate 320, and then the support truss 310 can be adjusted to a suitable position to perform laser marking on the jig consumable 400. After marking, the relative position of the jig carrier 330 and the jig pressing plate 320 remains unchanged, and the jig carrier 330 is rotated, and the jig pressing plate 320 also rotates, and the jig consumable 400 is flipped. After flipping to a suitable position, the support truss 310 can be changed to a suitable position again, and the other side of the jig consumable 400 is laser marked.

[0040] In one embodiment, for example, Figure 1As shown, a transmission member is also arranged between the first motor 510 and the rotating part, and the transmission member includes a first transmission wheel 520, a second transmission wheel 530 and a rack. The first transmission wheel 520 is arranged on the output shaft of the first motor 510, the second transmission wheel 530 is arranged on the rotating part, and the rack is sleeved on the first transmission wheel 520 and the second transmission wheel 530. The first motor 510 rotates to drive the first transmission wheel 520 to rotate, and the first transmission wheel 520 drives the second transmission wheel 530 to rotate through the rack, and the second transmission wheel 530 drives the rotating part to rotate to complete the transmission action. Through the transmission of the first transmission wheel 520, the second transmission wheel 530 and the rack, it is possible to avoid slipping between the rack and the first transmission wheel 520, the second transmission wheel 530, and mis-transmission, so that the transmission process between the first motor 510 and the fixture carrier 330 is stable and reliable, and then the flipping process of the fixture carrier 330 is stable and reliable, and errors are prevented in the transmission process, which causes the fixture consumables 400 to fall, bump, etc., and improve the reliability of this embodiment.

[0041] Please continue reading Figure 1 Exemplarily, the radius of the first transmission wheel 520 is set to R1, and the radius of the second transmission wheel 530 is set to R2, satisfying: R1<R2. The radius of the first transmission wheel 520 and the second transmission wheel 530 is limited, that is, the transmission ratio between the first motor 510 and the fixture carrier 330 is controlled, that is, the rotation speed of the fixture carrier 330 is controlled. If the radius of the first transmission wheel 520 is smaller than the radius of the second transmission wheel 530, the rotation speed will be reduced when the rotation of the first transmission wheel 520 is transmitted to the second transmission wheel 530. In this way, the first motor 510 rotates, driving the fixture carrier 330 to rotate at a lower speed, which can make the rotation process of the fixture carrier 330 more stable, avoid the fixture carrier 330 rotating too fast, causing the fixture consumables 400 to fall, and further improve the reliability of this embodiment.

[0042] In one embodiment, for example, Figure 1 As shown, a bearing groove is provided on the jig carrier 330, and a marking hole is provided in the bearing groove, and the marking hole is set as a through hole; a marking hole is also provided on the jig pressure plate 320 accordingly. A marking hole is provided on the jig pressure plate 320, and when the laser 200 is started and the jig consumables 400 are laser-marked, the laser can pass through the marking hole and directly hit the jig consumables 400, so as to avoid the laser emitted by the laser 200 from contacting the jig pressure plate 320 and affecting the normal progress of the marking operation. Correspondingly, a marking hole is provided on the jig carrier 330, so that after the jig carrier 330 and the jig pressure plate 320 are flipped together, when the jig carrier 330 faces the laser 200, the laser 200 can perform the marking operation on the jig consumables 400.

[0043] A bearing groove is provided on the jig carrier 330. When placing the jig consumable 400, it can be directly placed in the bearing groove. The bearing groove limits the jig consumable 400 in the horizontal direction, and the jig pressing plate 320 limits the jig consumable 400 in the vertical direction. The bearing groove cooperates with the jig pressing plate 320 to ensure that the jig carrier 330 and the jig pressing plate 320 limit the jig consumable 400 reliably. In addition, the marking hole is provided in the bearing groove, which can also enable the bearing groove to position the jig consumable 400. That is to say, when using the laser marking device of this embodiment, before placing the jig consumable 400, the laser 200 can be controlled to position the bearing groove part. After placing the jig consumable 400, laser marking can be directly performed, making the use process of this embodiment more flexible.

[0044] It is understandable that the cross section of the marking hole is smaller than the cross section of the bearing slot, and when the jig consumable 400 is placed in the bearing slot, it can fit in the bearing slot. In this way, the bearing slot limits the jig consumable 400 firmly and reliably, and when the jig carrier 330 is turned over and rotated to any angle, the jig consumable 400 will not fall out of the bearing slot, further making this embodiment more convenient to use.

[0045] In one embodiment, for example, Figure 1 As shown, the jig carrier 330 is provided with a plurality of bearing grooves, and correspondingly, the jig carrier 330 and the jig pressure plate 320 are provided with a plurality of marking holes. In this way, the jig carrier 330 can fix a plurality of jig consumables 400 at the same time for marking. When marking, the laser 200 can be moved to any position above the jig carrier 330 through the cooperation of the first transmission rod and the second transmission rod, and laser marking of jig consumables 400 at any position can be performed, thereby further improving the marking efficiency of this embodiment.

[0046] In one embodiment, for example, Figure 1 As shown, the laser 200 is arranged at the end of the frame 100, and the laser 200 is arranged in the direction of the frame 100; the bearing assembly 300 is arranged on the end of the frame 100 away from the laser 200. The bearing assembly 300 and the laser 200 are respectively arranged at the two ends of the frame 100, so that when operating the bearing assembly 300, the operator does not need to get close to the laser 200, which prevents accidental contact and misoperation of the laser 200, thereby improving the safety of this embodiment. Furthermore, during the marking operation, it is also convenient for the bearing assembly 300 to slide along the frame 100, so that the laser 200 can be focused, ensuring that this embodiment can operate normally, and improving the reliability of this embodiment.

[0047] In one embodiment, for example, Figure 1As shown, a slide groove is provided on the frame 100, and the slide groove extends in the direction from the laser 200 to the bearing assembly 300, and the bearing assembly 300 can be slidably installed in the slide groove. Specifically, the sliding part of the support truss is installed in the slide groove, and the moving track of the bearing assembly 300 is restricted by the slide groove, so that the bearing assembly 300 can only slide in the direction in which the slide groove extends. The direction of the slide groove is set according to the laser emission direction of the laser 200, so that when the bearing assembly 300 moves along the slide groove, it is convenient to cooperate with the laser 200 for focusing, so as to facilitate the subsequent laser marking operation.

[0048] In one embodiment, for example, Figure 1 As shown, the frame 100 is provided with a second motor 610, which is provided on the frame 100 and can drive the bearing assembly 300 to slide along the slide groove. The bearing assembly 300 is controlled by the second motor 610, so that the movement of the bearing assembly 300 is more stable and reliable.

[0049] It should be noted that, in the present embodiment, the first motor 510 and the second motor 610 are both provided with data transmission components, that is, the first motor 510 and the second motor 610 can be remotely controlled. In this way, when marking operation is required, it is only necessary to place the jig consumables 400, and remote operation can be performed to control the first motor 510 and the second motor 610, drive the bearing assembly 300 to move to a suitable position, and then start the laser 200. When the marking on one side of the jig consumables 400 is completed and needs to be flipped, the first motor 510 can also be remotely controlled to complete it, thereby reducing the operating difficulty of the present embodiment. At the same time, remote operation can also prevent the operator from being too close to the laser 200, and prevent the operator from being nearby when the laser 200 emits a laser, thereby improving the safety of the present embodiment.

[0050] In one embodiment, for example, Figure 1 As shown, a shooting assembly 700 is also provided on the frame 100. The shooting assembly 700 is arranged at a position close to the laser 200 on the frame 100, and the shooting assembly 700 is arranged in the direction of the bearing assembly 300. The shooting assembly 700 is arranged at a position close to the laser 200. When performing laser marking operation, the shooting assembly 700 can record the entire marking process and retain the working image, which is convenient for the subsequent information verification of the fixture consumables 400. Furthermore, the laser 200 and the shooting assembly 700 can be arranged on the second transmission rod, or the shooting assembly 700 can be arranged on the outer wall of the laser 200, so that the laser 200 and the shooting assembly 700 can move synchronously. In this way, when adjusting the laser 200, the shooting assembly 700 can follow the adjustment synchronously, and it is no longer necessary to adjust it separately, which further improves the convenience of this embodiment.

[0051] It is understandable that the shooting component 700 can be configured as any device capable of shooting and recording the marking operation process. Exemplarily, the shooting component 700 is configured as a camera.

[0052] In one embodiment, illustratively, a control component can be provided at the end of the frame 100 close to the laser 200, and the control component and the laser 200 are respectively arranged on both sides of the frame 100. The control component includes a screen and a control circuit board, and the first motor 510 and the second motor 610 are both electrically connected to the control circuit board, and the screen is also electrically connected to the control circuit board. When using this embodiment, after the power is turned on, the control circuit board transmits and displays the states of the first motor 510 and the second motor 610 on the screen, and the operator can make subsequent operations through the screen display content and the current state of the device, and laser mark the fixture consumables 400, making this embodiment easier to operate. It should be noted that the control component and the laser 200 are respectively arranged on both sides of the frame 100, that is, when the operator operates this embodiment or watches the screen display content, he is also in a position away from the laser 200, which improves the safety of this embodiment and ensures the personal safety of the operator.

[0053] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
