Description

Technical Field

[0001] The invention belongs to the technical field of laser marking machines, and in particular relates to an adjusting device of a laser marking machine and a laser marking machine. Background Art

[0002] Laser marking machine is a device that uses high-energy laser beams to mark the surface of various materials permanently. Its operating principle is to irradiate the surface of the workpiece with a high-energy laser beam, so that the surface material quickly heats up and reaches the ignition point, thereby evaporating and exposing the deep material, forming the required text, pattern and image. Since the whole process is non-contact, no mechanical pressure will be generated on the workpiece, so the surface of the workpiece will not be damaged. Based on the high-precision and non-contact characteristics of laser marking machines, it is widely used in electronic components, integrated circuits (ICs), electrical appliances, mobile communications, precision instruments, glasses and clocks and other fields.

[0003] The laser marking machine on the market generally includes a column and a laser marking head. The column is fixedly installed on the table, while the laser marking head can be installed on the column in a liftable manner. When using a laser marking machine, the height of the laser marking head on the column needs to be flexibly adjusted according to the height of the product, and then the focal length of the lens of the laser marking head can be adjusted. However, the existing laser marking head can only be adjusted in the up and down directions, resulting in limitations in the adjustment range of the laser marking head, and it cannot meet the adjustment requirements of multiple angles; in addition, since the column is fixedly installed on the table, when the laser marking machine is not in use, the column and the laser marking head are easy to occupy the table space, and it is also easy to adhere to dust.

[0004] Therefore, in view of the above technical problems, it is necessary to provide an adjustment device for a laser marking machine and a laser marking machine.

[0005] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0006] The object of the present invention is to provide an adjustment device for a laser marking machine and a laser marking machine, which can solve the problem that the adjustment range of the laser marking head is limited and cannot be folded and stored.

[0007] In order to achieve the above object, a technical solution provided by a specific embodiment of the present invention is as follows:

[0008] An adjustment device for a laser marking machine, comprising: a workbench, an adjustment mechanism and a marking mechanism;

[0009] A marking platform is installed on the workbench, and a working cavity and a receiving cavity are excavated on the workbench, and the working cavity is connected with the receiving cavity;

[0010] The adjustment mechanism comprises a bottom plate, the bottom plate is slidably arranged in the working chamber, a rotating disk is installed on the bottom plate, a pair of connecting plates are fixedly installed on the rotating disk, a column is rotatably connected between the pair of connecting plates, and a connecting mechanism is installed on the column;

[0011] The marking mechanism is rotatably connected to the connecting mechanism. The marking mechanism comprises a connecting arm. A laser marking head is installed on the connecting arm. The laser marking head corresponds to the marking platform.

[0012] In one or more embodiments of the present invention, an adjustment groove is excavated at the bottom of the working chamber, and the adjustment groove is used to accommodate the adjustment screw and the adjustment block, so that the adjustment mechanism and the marking mechanism can move between the working chamber and the storage chamber, that is, when the marking mechanism is in use, the adjustment mechanism and the marking mechanism will move into the working chamber, and when the marking mechanism is not in use, the adjustment mechanism and the marking mechanism will be stored in the storage chamber;

[0013] A avoidance cavity is excavated at the bottom of the storage cavity, and the avoidance cavity corresponds to the laser marking head, so as to better store the laser marking head and avoid the laser marking head from contacting the bottom of the storage cavity, thereby ensuring the safety of storing the laser marking head.

[0014] In one or more embodiments of the present invention, an adjusting screw is rotatably connected in the adjusting groove, an adjusting motor is installed in the workbench, and the adjusting screw is connected to the output shaft of the adjusting motor. When the adjusting motor is running, the adjusting motor can drive the adjusting screw to rotate.

[0015] In one or more embodiments of the present invention, an adjustment block is fixedly connected to the bottom of the base plate, and the adjustment block is slidably disposed in the adjustment groove and is threadedly connected to the adjustment screw. When the adjustment screw rotates, the adjustment block is moved in the adjustment groove under the action of the thread, and the position of the adjustment mechanism and the marking mechanism can be adjusted, so that the adjustment mechanism and the marking mechanism can move in the working chamber and the storage chamber.

[0016] In one or more embodiments of the present invention, a first rotating motor is installed on one of the connecting plates, and the output shaft of the first rotating motor is fixedly connected to the column. When the first rotating motor is running, the output shaft of the first rotating motor can drive the column to rotate, thereby changing the angle between the base plate and the column, so as to unfold or store the column.

[0017] In one or more embodiments of the present invention, a lifting slot is provided in the column, and the connecting mechanism includes a lifting block, which is slidably arranged in the lifting slot. The top wall of the column is connected to a lifting motor, and the output shaft of the lifting motor is fixedly connected to a lifting screw, and the lifting screw is threadedly connected to the lifting block. When the lifting motor is running, the lifting motor can drive the lifting screw to rotate. Since the lifting block is threadedly connected to the lifting screw, the lifting block can move up and down in the lifting slot to adjust the upper and lower heights of the marking mechanism so that the marking mechanism can better perform laser marking.

[0018] In one or more embodiments of the present invention, a U-shaped frame is fixedly connected to the lifting block, and the side wall of the column is provided with a stabilizing groove matching the U-shaped frame. The U-shaped frame moves in the stabilizing groove, which can increase the stability of the lifting block when it moves up and down, avoid shaking of the marking mechanism, and ensure that the marking mechanism can be lifted and lowered safely and stably.

[0019] In one or more embodiments of the present invention, a second rotary motor is installed in the lifting block, and the output shaft of the second rotary motor is connected to the rotary shaft.

[0020] The upper and lower sides of the U-shaped frame are fixedly connected with reinforcement plates, and the reinforcement plates are fixedly connected with positioning pins.

[0021] In one or more embodiments of the present invention, a connecting frame is installed on the connecting arm, and the connecting frame is fixedly connected to the rotating shaft. When the rotating shaft rotates, the rotating shaft can drive the connecting frame to rotate, and then drive the connecting arm and the laser marking head to rotate, so as to change the angle between the connecting arm and the column, so as to realize the expansion or folding of the connecting arm and the laser marking head;

[0022] A pair of positioning rails are connected to one side of the connecting frame close to the U-shaped frame, and a pair of positioning pins are slidably arranged in the pair of positioning rails respectively. By moving the positioning pins in the positioning rails, the stability of the connecting arm and the laser marking head during rotation can be increased, thereby ensuring that the laser marking head can rotate stably.

[0023] A laser marking machine comprises the adjusting device of the laser marking machine.

[0024] Compared with the prior art, the adjustment device of the laser marking machine and the laser marking machine of the present invention can adjust the position of the laser marking head in a larger range to meet the user's needs for multi-angle adjustment of the laser marking head. At the same time, it can also realize the folding storage of the column and the laser marking head to avoid occupying too much table space and reduce dust adhesion to a certain extent.

DETAILED DESCRIPTION

[0040] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0041] like Figures 1 to 12 As shown, an adjustment device for a laser marking machine in one embodiment of the present invention includes a workbench 1, an adjustment mechanism 2 and a marking mechanism 3.

[0042] A marking table 101 is installed on the workbench 1 , and the product to be marked is placed on the marking table 101 , and then the laser marking head 302 is used to mark the product.

[0043] In addition, a working chamber 102 and a storage chamber 103 are excavated on the workbench 1, and the working chamber 102 is connected to the storage chamber 103. When the marking mechanism 3 is marking the product, the adjusting mechanism 2 and the marking mechanism 3 will move into the working chamber 102 to mark the product. When the marking mechanism 3 is not in use, the adjusting mechanism 2 and the marking mechanism 3 will move into the storage chamber 103, and then the adjusting mechanism 2 and the marking mechanism 3 will be folded so that the adjusting mechanism 2 and the marking mechanism 3 are parallel to each other, and finally the adjusting mechanism 2 is controlled to rotate 90°, and the adjusting mechanism 2 and the marking mechanism 3 are stored in the storage chamber 103, that is, Figure 4 The state shown can avoid the adjustment mechanism 2 and the marking mechanism 3 from occupying the table space, and can also reduce dust adhesion to a certain extent.

[0044] Preferably, the working chamber 102 and the receiving chamber 103 surround the marking platform 101, that is, Figure 1In the state shown, the working chamber 102 and the storage chamber 103 form an L-shape as a whole, so as to fold and store the adjustment mechanism 2 and the marking mechanism 3.

[0045] Specifically, a avoidance cavity 104 is opened at the bottom of the storage cavity 103, and the avoidance cavity 104 corresponds to the laser marking head 302. When the marking mechanism 3 is stored in the storage cavity 103, part of the laser marking head 302 will be stored in the adjusting screw 105 to avoid the laser marking head 302 from contacting the bottom of the storage cavity 103, thereby ensuring the safety of the laser marking head 302 being stored.

[0046] like Figures 1 to 12 As shown, an adjustment groove is cut at the bottom of the working chamber 102, and the adjustment groove is used to accommodate the adjustment screw 105 and the adjustment block 202, so that the adjustment mechanism 2 and the marking mechanism 3 can move between the working chamber 102 and the storage chamber 103, that is, when the marking mechanism 3 is in use, the adjustment mechanism 2 and the marking mechanism 3 will move into the working chamber 102. When the marking mechanism 3 is not in use, the adjustment mechanism 2 and the marking mechanism 3 will be stored in the storage chamber 103.

[0047] Among them, an adjusting screw 105 is rotatably connected in the adjusting groove, an adjusting motor is installed in the workbench 1, and the adjusting screw 105 is connected to the output shaft of the adjusting motor. When the adjusting motor is running, the adjusting motor can drive the adjusting screw 105 to rotate. Since the adjusting block 202 is threadedly connected to the adjusting screw 105, the adjusting block 202 can move in the adjusting groove.

[0048] like Figures 1 to 12 As shown, the adjustment mechanism 2 includes a bottom plate 201 , which is slidably disposed in the working chamber 102 , and the bottom plate 201 is used to install a column 205 .

[0049] Among them, an adjustment block 202 is fixedly connected to the bottom of the bottom plate 201, and the adjustment block 202 is slidably arranged in the adjustment groove and is threadedly connected with the adjustment screw 105. When the adjustment screw 105 rotates, the adjustment block 202 is moved in the adjustment groove by the action of the thread, and then the position of the adjustment mechanism 2 and the marking mechanism 3 can be adjusted, so that the adjustment mechanism 2 and the marking mechanism 3 can move in the working chamber 102 or the storage chamber 103, which not only facilitates the laser marking head 302 to better mark the product, but also can realize the folding and storage of the adjustment mechanism 2 and the marking mechanism 3.

[0050] In addition, a turntable 203 is installed on the base plate 201, and the turntable 203 is rotatably connected to the base plate 201. By rotating the turntable 203 and the base plate 201, the inclination angle of the laser marking head 302 can be fine-tuned so that the laser marking head 302 can better mark the product on the marking table 101, and then the position of the laser marking head 302 can be adjusted in a larger range to meet the user's needs for multi-angle adjustment of the laser marking head 302.

[0051] Specifically, a pair of connecting plates 204 are fixedly installed on the turntable 203, and a column 205 is rotatably connected between the pair of connecting plates 204. The column 205 can be fixed through the cooperation between the connecting plates 204 and the first rotating motor 206 to ensure that the laser marking head 302 can stably mark the product.

[0052] Preferably, the rotation angle range of the column 205 is 0-90°. Figure 4 In the example, the angle of the column 205 is 0°. Figure 3 In the figure, the angle of the column 205 is 90°.

[0053] In addition, a first rotary motor 206 is installed on one of the connecting plates 204, and the output shaft of the first rotary motor 206 is fixedly connected to the column 205. When the first rotary motor 206 is running, the output shaft of the first rotary motor 206 can drive the column 205 to rotate, thereby changing the angle between the bottom plate 201 and the column 205, so as to expand or store the column 205.

[0054] At the same time, when the adjustment mechanism 2 moves into the working chamber 102, the first rotary motor 206 can also be operated according to different products, so that the column 205 is tilted toward the side close to the marking table 101, that is, Figure 1 The state shown allows the laser marking head 302 to better mark the product on the marking table 101 , and the position of the laser marking head 302 can be adjusted in a wider range to meet the user's needs for adjusting the laser marking head 302 at multiple angles.

[0055] Preferably, the first rotating motor 206 is a servo motor, and the first rotating motor 206 has a self-locking function, that is, when the first rotating motor 206 is not running, the output shaft of the first rotating motor 206 can be self-locked and fixed, thereby keeping the column 205 stable to ensure the safety of the laser marking head 302 during marking.

[0056] like Figures 1 to 12 As shown, a lifting slot 207 is provided in the column 205 , and the lifting slot 207 is used to accommodate a lifting block 208 .

[0057] Among them, a connecting mechanism is installed on the column 205, which is used to connect the marking mechanism 3. At the same time, the column 205 and the marking mechanism 3 can be rotated, which not only facilitates the laser marking head 302 to better mark the product, but also allows the marking mechanism 3 to be folded so that the marking mechanism 3 can be stored, thereby avoiding the marking mechanism 3 occupying the table space of the workbench 1.

[0058] Specifically, the connection mechanism includes a lifting block 208, which is slidably disposed in the lifting slot 207, and a lifting motor 209 is connected to the top wall of the column 205. The output shaft of the lifting motor 209 is fixedly connected to a lifting screw, and the lifting screw is threadedly connected to the lifting block 208. When the lifting motor 209 is running, the lifting motor 209 can drive the lifting screw to rotate. Since the lifting block 208 is threadedly connected to the lifting screw, the lifting block 208 can move up and down in the lifting slot 207, so as to adjust the upper and lower heights of the marking mechanism 3 according to different products, so that the marking mechanism 3 can better perform laser marking.

[0059] like Figures 1 to 12 As shown, a U-shaped frame 210 is fixedly connected to the lifting block 208, and a stabilizing groove 211 matching the U-shaped frame 210 is provided on the side wall of the column 205. By the U-shaped frame 210 moving in the stabilizing groove 211, the stability of the lifting block 208 when moving up and down can be increased, and the shaking of the marking mechanism 3 can be avoided, so as to ensure that the marking mechanism 3 can be lifted and lowered safely and stably.

[0060] Among them, a second rotary motor is installed in the lifting block 208, and the output shaft of the second rotary motor is connected to the rotary shaft 212. When the second rotary motor is running, the second rotary motor can drive the rotary shaft 212 to rotate. Since the rotary shaft 212 is fixedly connected to the connecting frame 303, the rotary shaft 212 can drive the connecting frame 303, the connecting arm 301 and the laser marking head 302 to rotate, which not only facilitates the laser marking head 302 to better mark the product on the marking table 101, but also can fold and store the connecting arm 301 and the laser marking head 302 to avoid the marking mechanism 3 occupying space.

[0061] like Figures 1 to 4 As shown, when the laser marking head 302 is in the working state, an angle is formed between the connecting arm 301 and the column 205. When the laser marking head 302 is in the folded state, the connecting arm 301 and the column 205 are parallel.

[0062] In addition, the upper and lower sides of the U-shaped frame 210 are fixedly connected with reinforcing plates 213, and the reinforcing plates 213 are fixedly connected with positioning pins 214. By sliding the positioning pins 214 in the positioning rails 304, the stability of the connecting arm 301 and the laser marking head 302 during rotation can be improved.

[0063] like Figures 1 to 12As shown, a third rotating motor is installed in the bottom plate 201, and the output shaft of the third rotating motor is connected to a rotating gear 215. When the third rotating motor is running, the third rotating motor can drive the rotating gear 215 to rotate.

[0064] The side wall of the turntable 203 is provided with a rack 216, and the rotating gear 215 meshes with the rack 216. When the rotating gear 215 rotates, the turntable 203 is rotatably connected to the bottom plate 201 because the rotating gear 215 meshes with the rack 216. Therefore, the rack 216 is meshed to drive the turntable 203 to rotate, and the turntable 203 can drive the adjustment mechanism 2 and the marking mechanism 3 to rotate to fine-tune the inclination angle of the laser marking head 302, and then the position of the laser marking head 302 can be adjusted in a wider range to meet the user's needs for adjusting the laser marking head 302 at multiple angles, so that the laser marking head 302 can better perform laser marking on the product.

[0065] Preferably, the tilt angle of the laser marking head 302 ranges from 0° to 15°.

[0066] In addition, a cylinder 217 is installed on the rotating disk 203, and a fixing plate 218 is connected to the free end of the cylinder 217. A plurality of needles 219 are installed on the fixing plate 218. A through slot matching the fixing plate 218 is provided in the rotating disk 203, and the needles 219 are in contact with the bottom plate 201. When the rotating disk 203 does not need to rotate, the cylinder 217 is extended, and the cylinder 217 drives the fixing plate 218 and the needles 219 to move, so that the needles 219 are in contact with the bottom plate 201. The rotating disk 203 can be locked and fixed by the needles 219 to prevent the rotating disk 203 from rotating.

[0067] When the turntable 203 needs to rotate, the cylinder 217 contracts, causing the fixed plate 218 and the needle 219 to contract in the through slot, and then the third rotating motor is operated, which drives the rotating gear 215 to operate, and the turntable 203 can be rotated through the meshing action of the rotating gear 215 and the rack 216.

[0068] like Figures 1 to 12 As shown, the marking mechanism 3 is rotatably connected to the connecting mechanism, and the marking mechanism 3 is used to mark the product on the marking platform 101 .

[0069] The marking mechanism 3 includes a connecting arm 301, on which a laser marking head 302 is mounted, and the laser marking head 302 corresponds to the marking platform 101. The laser marking head 302 can be used to mark the product on the marking platform 101.

[0070] In addition, a connecting frame 303 is installed on the connecting arm 301, and the connecting frame 303 is fixedly connected to the rotating shaft 212. When the rotating shaft 212 rotates, the rotating shaft 212 can drive the connecting frame 303 to rotate, and then drive the connecting arm 301 and the laser marking head 302 to rotate, so as to change the angle between the connecting arm 301 and the column 205, so as to realize the expansion or folding of the connecting arm 301 and the laser marking head 302, that is, when the angle between the connecting arm 301 and the column 205 is 0, the marking mechanism 3 is in a folded state; when the angle between the connecting arm 301 and the column 205 is not equal to 0, the marking mechanism 3 is in a working state.

[0071] Specifically, a pair of positioning rails 304 are connected to one side of the connecting frame 303 close to the U-shaped frame 210, and a pair of positioning pins 214 are respectively slidably disposed in the pair of positioning rails 304. By the positioning pins 214 moving in the positioning rails 304, the stability of the connecting arm 301 and the laser marking head 302 during rotation can be increased, ensuring that the laser marking head 302 can rotate stably.

[0072] A laser marking machine includes an adjustment device for the laser marking machine and a cover plate 4, wherein the cover plate 4 is arranged on a working chamber 102 and a storage chamber 103, thereby preventing external dust from entering the working chamber 102 or the storage chamber 103, so as to ensure the clean effect of the laser marking head 302 in the storage chamber 103.

[0073] Preferably, the cover plate 4 is L-shaped, that is Figure 4 Status shown.

[0074] In order to ensure that the workbench 1 has a flush surface, step holes are provided at the openings of the working chamber 102 and the storage chamber 103, and the cover plate 4 is installed in the step holes, and the cover plate 4 is made of high-strength metal.

[0075] In specific use, when a product needs to be laser marked, the product to be marked is placed on the marking table 101 and fixed using a clamp or other equipment.

[0076] Remove the cover plate 4, operate the first rotary motor 206, and the first rotary motor 206 drives the column 205 to rotate, that is, the column 205 rotates from the 0° state to the 90° state. Figure 3 When the column 205 has completed its rotation, the first rotating motor 206 is stopped, and the column 205 is fixed by utilizing the self-locking function of the first rotating motor 206 .

[0077] The adjusting motor in the operating workbench 1 drives the adjusting screw 105 to rotate. Since the adjusting block 202 is threadedly connected to the adjusting screw 105, the adjusting block 202 can move in the adjusting groove under the action of the thread, thereby enabling the base plate 201, the column 205 and the marking mechanism 3 to move from the storage chamber 103 to the working chamber 102.

[0078] The second rotating motor in the lifting block 208 is operated, and the second rotating motor drives the rotating shaft 212 to rotate. Since the rotating shaft 212 is fixedly connected to the connecting frame 303, the rotating shaft 212 can drive the connecting frame 303, the connecting arm 301 and the laser marking head 302 to rotate. At the same time, a pair of positioning pins 214 can move in a pair of positioning rails 304 respectively to ensure the stability of the connecting arm 301 and the laser marking head 302 during rotation. Then the laser marking head 302 is operated to mark the product on the marking platform 101.

[0079] In addition, according to different products, the column 205 can be adjusted so that the column 205 is in a non-90° state, such as Figure 1 As shown, the column 205 is in the 80° state.

[0080] At the same time, the third rotating motor can also be operated, and the third rotating motor drives the rotating gear 215 to operate. Through the meshing action of the rotating gear 215 and the rack 216, the turntable 203, the column 205, the connecting arm 301 and the laser marking head 302 can be rotated, so as to fine-tune the inclination angle of the laser marking head 302 in the horizontal direction, so that the laser marking head 302 can better mark the product, and the laser marking head 302 can also be adjusted in a wider range to meet the user's needs for adjusting the laser marking head 302 at multiple angles, so that the laser marking head 302 can better perform laser marking on the product.

[0081] When it is not necessary to mark the product, the first rotary motor 206 is controlled to operate so that the column 205 is at a 90° state, and then the third rotary motor is operated so that the connecting arm 301 rotates to be parallel to the column 205. The adjusting motor is operated so that the bottom plate 201, the column 205, the connecting arm 301 and the laser marking head 302 move from the working chamber 102 to the storage chamber 103.

[0082] Then, the first rotating motor 206 is operated to rotate the column 205 and the connecting arm 301 from the 90° state to the 0° state. At this time, the column 205, the connecting arm 301 and the laser marking head 302 are all in the storage chamber 103. Figure 4As shown, by covering the cover plate 4 at the ports of the working chamber 102 and the storage chamber 103, the adjustment mechanism 2 and the marking mechanism 3 can be stored, which can not only prevent the adjustment mechanism 2 and the marking mechanism 3 from occupying the table space of the workbench 1, but also prevent dust from adhering to the surface of the laser marking head 302.
