Description

Technical Field

[0001] The invention belongs to the technical field of laser marking, and in particular relates to a card-matching laser marking machine. Background Art

[0002] Laser marking machines use laser beams to make permanent marks on the surfaces of various materials. The effect of marking is to expose the deeper materials through the evaporation of the surface materials, or to "carve" traces through the chemical and physical changes of the surface materials caused by light energy, or to burn part of the material through light energy to reveal the required etching patterns, text, barcodes and other graphics.

[0003] However, when the laser marking machine in the prior art is marking a plastic pipe made of a relatively soft material, due to the limitation of the material of the pipe itself, the existing clamping device usually drives the pipe to rotate so as to mark different positions on the pipe. When the clamping device in the prior art drives the pipe to rotate, an active clamping part usually drives another driven clamping part to clamp and rotate the pipe. However, since the material of the plastic pipe itself is relatively soft, when the clamping is too tight, it will be affected by the moving virtual position, which will not only cause distortion and damage to the pipe itself, but also affect the accuracy of pipe marking.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a card-type laser marking machine.

DETAILED DESCRIPTION

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] See also Figure 1-6 As shown, in this embodiment, a card-type laser marking machine is provided, comprising a processing seat 1, a laser marking mechanism 2 and a control console 3 are respectively installed on the upper side of the processing seat 1, a processing table 4 is installed on the upper side of the processing seat 1, and a moving mechanism connected to the processing table 4 is installed in the processing seat 1;

[0028] An adjusting seat 5 and a fixed seat 6 are respectively installed on the upper side of the processing table 4, and a moving assembly 7 connected to the adjusting seat 5 is installed on the upper side of the processing table 4. Two first rope wheels 8 are rotatably matched in the adjusting seat 5, and one side of the two first rope wheels 8 are rotatably matched with a fixed cone 13 and a fixed head 9, respectively. A cavity is provided in the processing table 4, and a connecting cylinder 10 is installed in the cavity. A sliding member 11 is slidably matched in the connecting cylinder 10. Two second rope wheels 12 are fixedly connected to one end of the connecting cylinder 10 and the sliding member 11, and a connecting rope 14 is installed between the second rope wheels 12 and the first rope wheels 8 opposite to each other, and an elastic assembly 15 corresponding to the connecting rope 14 is installed in the processing table 4.

[0029] The application of one aspect of this embodiment is as follows: when in use, first adjust the adjustment seat 5 on the movable assembly 7 according to the size of the pipe to be marked, and fix the pipe between the movable seat 5 and the fixed seat 6, and then control the laser marking mechanism 2 to mark the pipe through the control console 3. When one side of the pipe is processed, the first pulley 6 on the fixed seat 6 can be controlled to rotate. The rotation of the first pulley 6 can drive the connecting rope 14 to move. The movement of the connecting rope 14 can drive the connecting tube 10 to rotate through the sliding member 11. The rotation of the connecting tube 10 can drive another second pulley 12 connected to the connecting tube 10 to rotate, so that the fixed cone 13 on one side of the other first pulley 8 can be driven to rotate through the connecting rope 14, so that the pipe can be driven to rotate. Finally, the laser marking mechanism 2 is started again through the control console 3 to mark the pipe.

[0030] By means of the connecting rope 14, the first rope wheel 12 and the first rope wheel 12 can be cooperated with to drive the fixed cone 13 and the fixed head 9 at one end of the first rope wheel 12 to rotate synchronously. The displacement error caused by the moving virtual position in the transmission mode such as gears in the prior art can be reduced under the drive of the connecting rope 14, so that the pipe can be more accurately marked and the problem of damage to the pipe during marking can be avoided. By means of the sliding member 11, when the adjusting seat 5 and the fixing seat 6 are fixed to pipes of different sizes, the problem that the position between the adjusting seat 5 and the fixing seat 6 is changed, which will affect the two second rope wheels 12 and make them unusable due to the change in distance, can be avoided. Therefore, not only can pipes of different sizes be marked, but also the stability of clamping pipes of different sizes can be improved. By means of the elastic plastic member 15, the connecting rope 14 between the first rope wheel 8 and the second rope wheel 12 can be squeezed, so that the tightness of the connecting rope 14 can be adjusted, further reducing the influence of the moving virtual position on the pipes to be marked.

[0031] like Figure 2-4As shown, the sliding member 11 of this embodiment includes a square slide groove opened in the connecting tube 10, a square slide frame 16 is slidably matched in the square slide groove, one end of the square slide frame 16 is fixedly connected to a fixed tube 17 connected to the first rope pulley 12, a plurality of connecting grooves are opened on the peripheral side of the square slide frame 16, a plurality of pulleys 18 are elastically matched in the connecting groove, and a control member corresponding to the pulley 18 is installed in the square slide frame 16; the control member includes a rotating rod 19 rotatably matched in the square slide frame 16, a plurality of arc cams 20 corresponding to the pulley 18 are installed on the rotating rod 19, and a plurality of first elastic cams 20 are fixedly connected to the inner wall of the square slide frame 16 Spring, one end of each of the two first springs is fixedly connected to a mounting seat 21, and the pulley 18 rotatably fits in the mounting seat 21; one end of the rotating rod 19 is provided with a sliding groove, in which a moving rod 22 is slidably fitted, and one end of the moving rod 22 is fixedly connected to a threaded rod 23, and the inner wall of the sliding groove is provided with a limiting groove 24, in which a limiting plate 25 connected to the moving rod 22 is slidably fitted, and the threaded rod 23 is threadedly fitted with one side of the inner wall of the connecting tube 10, wherein one end of the rotating rod 19 passes through the fixed tube 17 and the second rope pulley 12 and extends to one side of the processing table 4, and a control disk 26 is fixedly connected to the rotating rod 19 on one side of the processing table 4.

[0032] By means of the provided pulley 18, the arc cam 20 can be driven to rotate under the rotation of the rotating rod 19. After the arc cam 20 rotates a certain angle, the mounting seat 21 can be fixed, so that the pulley 18 and the square slide groove in the connecting tube 10 can be squeezed against each other, which can not only reduce the influence of the square sliding frame 16 on the movement of the connecting tube 16 when transmitting the connecting tube 16, but also enable the pulley 18 to slide in the square slide groove, so that the adjusting seat 5 will not be stuck when moving, thereby making the adjusting seat 5 more stable when adjusting the distance of pipes of different sizes, and under the setting of the first spring, a continuous elastic force can be provided to the pulley 18, so that the mounting seat 21 is not squeezed by the arc cam 20. The pulley 18 and the square groove in the connecting tube 10 can be disengaged from each other to facilitate the replacement or maintenance of the rotating rod 19. The threaded rod 23 can be used to fix the rotating rod 19 after squeezing the pulley 18 on the mounting seat 21, and the movable rod 22 can be used to prevent the threaded rod 23 from driving the rotating rod 19 to rotate synchronously when it is threadedly engaged and fixed with the connecting tube 10, thereby changing the corresponding positions of the arc cam 20 and the mounting seat 21, thereby causing the problem that the pulley 18 cannot be lifted up. Under the setting of the first limit plate 25, the threaded rod 23 can be driven to rotate synchronously when the rotating rod 19 rotates, which can make the threaded rod 23 more stable when rotating.

[0033] like Figure 5As shown, the tension assembly 15 of this embodiment includes an inner cavity opened in the adjustment seat 5, the inner cavity is equipped with an elastic wheel 27 corresponding to the connecting rope 14, one side of the elastic wheel 27 is fixedly connected to a connecting block, one side of the connecting block is fixedly connected to an elastic member, one end of the elastic member is fixedly connected to a bearing 28, one side of the bearing 28 is equipped with a first screw rod 29, the first screw rod 19 is threadedly engaged with one side of the adjustment seat 5, wherein one side of the adjustment seat 5 is fixedly connected with an adjustment handle; the elastic member includes a sliding column 30 fixedly connected to the lower side of the connecting block, and a mounting cylinder 31 fixedly connected to the bearing 28, the sliding column 30 is elastically engaged in the mounting cylinder 31, wherein a second spring is fixedly connected in the mounting cylinder 31, and one end of the second spring is connected to the sliding column 3.

[0034] By setting the tension wheel 27, the elastic force of the second spring itself can provide continuous pressure to the connecting block at one end of the sliding column 30, and can drive the connecting rope 14 to move, and continuously squeeze the connecting rope 14, so that the connecting rope 14 can be kept in a continuous taut state, and the influence of the moving virtual position on the rotation of the pipe is further reduced. By setting the first screw rod 29, the position of the tension wheel 27 can be adjusted, and under the action of the bearing 28, the tension wheel 27 can be kept from rotating with the first screw rod 29, so as to avoid the situation that the tension wheel 27 rotates and cannot be used. And under the setting of the adjustment handle, it can be more convenient for the staff to operate.

[0035] like Figure 2 As shown, the moving assembly 7 of this embodiment includes two fixed plates 32 fixedly connected to the processing table 4, a second screw rod 33 is rotatably engaged between the two fixed plates 32, and the adjusting seat 5 is threadedly engaged on the second screw rod 33, wherein an operating handle is rotatably engaged on one side of the fixed plate 32, and the operating handle is connected to the second screw rod 33 through the fixed plate 32; a guide rod 34 is fixedly connected between the two fixed plates 32, and a guide groove is provided on the adjusting seat 5 that is slidably engaged on the guide rod 34.

[0036] By setting the second screw rod 33, the staff can easily rotate the second screw rod 33 under the setting of the operating handle. The rotation of the second screw rod 33 can drive the adjustment seat 5 to move, and under the limiting guidance of the guide rod 34, the adjustment seat 5 can be more stable when moving.

[0037] like Figure 6As shown, the moving mechanism of this embodiment includes a first moving block fixedly connected to the lower side of the processing table 4, a first fixed frame 35 is installed in the processing seat 1, a third screw rod 36 is rotatably engaged in the first fixed frame 35, and the first moving block is threadedly engaged on the third screw rod 36; a second moving block is fixedly connected to the lower side of the first fixed frame 25, a second fixed frame 37 is installed in the processing seat 1, a fourth screw rod 38 threadedly engaged with the second moving block is rotatably engaged in the second fixed frame 37, wherein one end of the first fixed frame 35 and the second fixed frame 37 are rotatably engaged with a control handle connected to the third screw rod 36 and the fourth screw rod 38.

[0038] By setting the third screw rod 36, the first movable block can be driven by the control handle to move in the first fixed frame 35, so that the longitudinal processing position of the processing table 4 can be adjusted to facilitate marking the longitudinal position on the pipe. Under the rotation of the fourth screw rod 28, the second movable block can be moved in the second fixed frame 37, so as to drive the processing table 4 to move horizontally, so as to facilitate marking the horizontal position of the pipe, making the marking position of the pipe more flexible and efficient.

[0039] like Figure 1 As shown, a movable groove is provided on the processing table 4 of this embodiment. The setting of the movable groove can facilitate the movement of the connecting rope 14 in the adjustment seat 5 and protect the connecting rope 14 when adjusting the marking orientation of the pipe.

By providing a double group of rope pulleys, the influence of displacement virtual position can be better avoided compared with the synchronous wheels in the prior art.
