Description

Technical Field

[0001] The invention belongs to the field of laser marking equipment, and in particular relates to laser marking equipment for producing automobile buttons. Background Art

[0002] Car buttons are a general term for various switches and control keys inside a car. They are usually used to control various functions of the car, including but not limited to lights, wipers, and audio systems. Car button laser marking is an advanced surface treatment process that uses the light energy conductor of the laser beam to cause chemical and physical changes in the surface material, thereby engraving the required graphics, text or patterns.

[0003] Existing publication number CN221363219U discloses a laser marking device for producing automobile buttons, including a box body, a mounting groove is opened on one side of the box body, a placing table is installed in the middle of the top of the box body, a laser machine body is fixedly installed on one side of the top of the box body, and an operating table is fixedly installed on one side of the laser machine body and located at the bottom of the box body, so as to solve the problem that the laser marking device is fixed in a way that the object is clamped by sliding a clamp block and then the fixing screw of the clamp block is rotated and fixed in the screw hole inside the slide groove, which requires personnel to operate and tighten, resulting in cumbersome clamping steps. At the same time, if the screws and the screw holes are used for a long time and the threads are slipped, the screws may not be tightened and the clamped object may fall off, thereby reducing the production efficiency and practicality of the marking equipment, thereby improving the work efficiency and practicality of the marking equipment.

[0004] The existing device also has the following deficiencies: 1. The existing device fixes the car button from the outside. The surface of the car button is usually smooth or frosted. Fixing and clamping from the outside often causes scratches and other damages to the surface, resulting in a high rate of defective products. The existing internal fixing technology requires first extending the fixing mechanism into the car button through a driving device, and then expanding the fixing mechanism through the driving device of the fixing mechanism to fix the car button. The work efficiency is low and the production cost is high.

[0005] 2. The existing device can only mark one angle of the button. For some car buttons that need to be marked at multiple angles (such as wiper rotary buttons), it is necessary to install and disassemble the rotary button to adjust the angle multiple times to complete the marking work, which seriously affects the work efficiency.

[0006] 3. When the existing laser marking equipment is working, its conveying, clamping, marking and unloading components are independent of each other and operate separately. The coordination between the components is poor and the working efficiency is low. Summary of the invention

[0007] The purpose of the present invention is to provide a laser marking device for producing automobile buttons in view of the problems raised in the above background technology.

[0008] To achieve the above object, the present invention adopts the following technical scheme: a laser marking device for producing automobile buttons, comprising: A workbench, wherein a conveyor belt is embedded in the workbench, the conveyor belt is driven by a motor, a discharge chute is provided on the top of the workbench, a control panel is provided on the upper surface of the workbench, a cavity is provided inside the workbench, and a plurality of evenly distributed laser marking machines are fixed on the workbench; A rotating assembly, the rotating assembly comprising a sleeve rotatably connected to the workbench, the bottom end of the sleeve extending into the cavity, a mounting plate fixed to the top end of the sleeve, and the rotating assembly driven by a transmission component; A clamping assembly, wherein the clamping assemblies are in plurality and are arranged in a circumferential array on the peripheral side wall of the mounting plate with the central axis of the mounting plate as the center; An angle adjustment component is used to adjust the angle of the clamping component.

[0009] Furthermore, the transmission component includes a groove wheel fixed on the sleeve, the groove wheel is provided with a plurality of evenly distributed sliding grooves, a first rotating shaft is rotatably connected inside the cavity, a dial is fixed on the first rotating shaft, and a cylindrical pin cooperating with the sliding groove is fixed on the dial.

[0010] Furthermore, the transmission component also includes a rotating seat fixed in the cavity, the rotating seat is rotatably connected to a second rotating shaft, both ends of the second rotating shaft are fixed with first bevel gears, and the rotating shaft of the conveyor belt and the first rotating shaft are fixed with a second bevel gear meshing with the first bevel gear.

[0011] Furthermore, the number of the slide grooves is the same as the number of the clamping components, and the angle between the axes of two adjacent laser marking machines is equal to the angle between two adjacent slide grooves.

[0012] Furthermore, the clamping assembly includes a plurality of ear seats evenly fixed on the mounting plate, the ear seat is provided with a through hole, a lifting rod passing through the through hole is provided in the through hole, an electric push rod is fixed to the bottom end of the ear seat, an extrusion plate is fixed to the output end of the electric push rod, the extrusion plate is slidably connected to the lifting rod, a limiting plate is fixed on the lifting rod, a spring is sleeved on the lifting rod between the limiting plate and the extrusion plate, two ends of the spring are respectively fixed on the extrusion plate and the limiting plate, a baffle is fixed to the top end of the lifting rod, and a rotating ring is rotatably connected to the baffle.

[0013] Furthermore, the clamping assembly also includes a plurality of connecting rods rotatably connected to the extrusion plate and a plurality of inner support rods rotatably connected to the bottom end of the lifting rod, the number of the connecting rods is the same as the number of the inner support rods, one end of the connecting rod away from the extrusion plate is rotatably connected to the inner support rod, and a rubber ball is fixed to one end of the inner support rod away from the lifting rod.

[0014] Furthermore, the angle adjustment assembly includes a rotating sleeve rotatably connected to the through hole, the lifting rod passes through the rotating sleeve, and a column gear is fixed to the top of the rotating sleeve.

[0015] Furthermore, the angle adjustment assembly also includes a support rod fixed on the workbench, two mounting rods are fixed on the support rod, and arc-shaped racks meshing with column gears are fixed on the ends of the two mounting rods away from the support rod.

[0016] Compared with the prior art, the advantages of the present invention are: The present invention arranges a transmission component. Every time the rotating shaft of the conveyor belt rotates one circle, the mounting plate is driven to rotate a specific angle (the angle is equal to the angle between the axes of two adjacent laser marking machines) under the action of the transmission component. The arrangement of the transmission component makes the cooperation between the conveyor belt and the rotating component more coordinated, which is beneficial to improving work efficiency. The rotating component does not need to be driven by an additional driving device, thereby reducing equipment costs.

[0017] The present invention provides a clamping assembly. When the clamping assembly rotates to above the conveyor belt, the lifting rod is pushed downward by the electric push rod. When the rotating ring contacts the rotating sleeve, the electric push rod pushes the extrusion plate downward to make the connecting rod open the inner support rod, so that the rubber ball abuts against the inner wall of the button to fix the button. When the clamping assembly rotates to above the unloading chute, the electric push rod is shortened to remove the marked automobile button. The rubber ball is fixed from the inside of the button to avoid scratches and other damage to the button during clamping, thereby reducing the defective rate of the product. In addition, the downward movement of the lifting rod and the expansion of the inner support rod are achieved only by a single driving source, without the need for multiple driving devices, thereby reducing the production cost of the equipment, simplifying the clamping steps, and improving work efficiency.

[0018] The present invention sets an angle adjustment component. When the clamping component contacts the arc-shaped rack, the laser marking machine performs the first marking on the button. Then the clamping component continues to rotate with the mounting plate. At the same time, under the meshing action of the arc-shaped rack and the column gear, the clamping component drives the car button to rotate to adjust the angle. When the clamping component rotates to the next laser marking machine position, the second marking is directly performed. There is no need to manually adjust the angle of the car button, and the work efficiency is high.

[0019] In the present invention, when the clamping assembly rotates to above the unloading chute, the electric push rod is shortened to unload the marked automobile button, without the need for additional unloading equipment, and the unloading operation and the marking work are carried out synchronously, which is conducive to improving work efficiency.

[0020] The marking work of the automobile button in the present invention is completed in one step from conveying, clamping, multi-angle marking to unloading, and the components cooperate with each other and operate simultaneously, which greatly improves the work efficiency and reduces the production cost of the equipment.

DETAILED DESCRIPTION

[0023] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0024] like Figure 1-Figure 8As shown, a laser marking device for producing automobile buttons includes a workbench 1, a rotating component, a clamping component and an angle adjustment component. A conveyor belt 11 is embedded in the workbench 1, and the conveyor belt 11 is driven by a motor. A discharge chute 12 is provided on the workbench 1, a control panel 13 is provided on the upper surface of the workbench 1, a cavity 14 is provided inside the workbench 1, and a plurality of evenly distributed laser marking machines 15 are fixed on the workbench 1.

[0025] During operation, the car buttons are evenly placed on the conveyor belt 11 through the unloading device, and the unloading device unloads once each time the rotating shaft of the conveyor belt 11 rotates one circle.

[0026] The rotating assembly includes a sleeve 21 rotatably connected to the workbench 1, the bottom end of the sleeve 21 extends into the cavity 14, and a mounting plate 22 is fixed to the top of the sleeve 21. The rotating assembly is driven by a transmission component, and the transmission component includes a groove wheel 23 fixed to the sleeve 21. The groove wheel 23 is provided with a plurality of evenly distributed slide grooves 230. The number of the slide grooves 230 is the same as the number of the clamping assembly. The angle between the axes of two adjacent laser marking machines 15 is equal to the angle between the two adjacent slide grooves 230. The cavity 14 is rotatably connected to the inner part of the sleeve 21. There is a first rotating shaft 24, a dial 25 is fixed on the first rotating shaft 24, a cylindrical pin 251 that cooperates with the slide groove 230 is fixed on the dial 25, the transmission component also includes a rotating seat 141 fixed in the cavity 14, the rotating seat 141 is rotatably connected to the second rotating shaft 26, both ends of the second rotating shaft 26 are fixed with first bevel gears 261, the rotating shaft of the conveyor belt 11 and the first rotating shaft 24 are fixed with a second bevel gear 27 that meshes with the first bevel gear 261, and the first bevel gear 261 and the second bevel gear 27 have the same number of teeth.

[0027] During operation, the conveyor belt 11 drives its rotating shaft to rotate. Under the joint action of the first bevel gear 261, the second bevel gear 27 and the second rotating shaft 26, the first rotating shaft 24 rotates synchronously, thereby driving the dial 25 to rotate. Every time the dial 25 rotates one circle, the cylindrical pin 251 drives the groove wheel 23 to rotate a specific angle (the angle is equal to the angle between the axes of two adjacent laser marking machines), realizing intermittent rotation of the rotating component.

[0028] There are multiple clamping components and they are evenly distributed on the mounting plate 22. The clamping components include multiple ear seats 31 evenly fixed on the mounting plate 22. The ear seats 31 are provided with through holes 310. The through holes 310 are provided with lifting rods 32 that penetrate through the through holes 310. An electric push rod 33 is fixed to the bottom end of the ear seats 31. An extrusion plate 34 is fixed to the output end of the electric push rod 33. The extrusion plate 34 is slidably connected to the lifting rod 32. A limit plate 35 is fixed to the lifting rod 32. A spring 36 is sleeved on the lifting rod 32 between the limit plate 35 and the extrusion plate 34. The two ends of the spring 36 are respectively fixed to the extrusion plate 34 and the limit plate 35. The lifting rod 3 2 is fixed with a baffle plate 321, and a rotating ring 3211 is rotatably connected to the baffle plate 321. The clamping assembly also includes a plurality of connecting rods 341 rotatably connected to the extrusion plate 34 and a plurality of inner support rods 322 rotatably connected to the bottom end of the lifting rod 32. The number of the connecting rods 341 and the inner support rods 322 is the same. The end of the connecting rod 341 away from the extrusion plate 34 is rotatably connected to the inner support rod 322. The end of the inner support rod 322 away from the lifting rod 32 is fixed with a rubber ball 3221. In this embodiment, there are six groups of clamping assemblies, three laser marking machines 15, and the angle between the axes of two adjacent laser marking machines 15 is 60°.

[0029] During operation, when the clamping assembly rotates to above the conveyor belt 11, the electric push rod 33 extends, and the extension of the electric push rod 33 pushes the lifting rod 32 to move downward. When the rotating ring 3211 contacts the rotating sleeve 1, the electric push rod 33 pushes the extrusion plate 34 to move downward so that the connecting rod 341 opens the inner support rod 322, so that the rubber ball 3221 abuts against the inner wall of the car button to fix the car button. When the mounting plate 22 rotates again, the clamping assembly drives the car button to rotate together. When the car button rotates to the position where the laser marking machine 15 is located, the laser marking machine 15 marks the car button. When the car button rotates to above the discharge chute 12, the electric push rod 33 shortens and the extrusion plate 34 moves upward relative to the lifting rod 32, so that the inner support rod 322 is retracted, and the rubber ball 3221 is separated from the car button, so that the car button falls into the discharge chute 12 under the action of gravity. After the spring 36 returns to its original shape, the electric push rod 33 continues to shorten and drives the lifting rod 32 to return to its initial height.

[0030] The angle adjustment assembly includes a rotating sleeve 41 rotatably connected to the through hole 310, the lifting rod 32 passes through the rotating sleeve 41, and a column gear 42 is fixed to the top of the rotating sleeve 41. The angle adjustment assembly also includes a support rod 43 fixed on the workbench 1, and two mounting rods 44 are fixed on the support rod 43. The ends of the two mounting rods 44 away from the support rod 43 are fixed with arc-shaped racks 45 meshing with the column gear 42.

[0031] During operation, when the clamping assembly contacts the arc-shaped rack 45, the car button rotates to the position of the first laser marking machine 15 for the first marking, and then the clamping assembly continues to rotate following the mounting plate 22. At the same time, under the meshing action of the arc-shaped rack 45 and the column gear 42, the clamping assembly drives the car button to rotate for angle adjustment, and the clamping assembly rotates to the position of the next laser marking machine 15 for marking again.

[0032] The working principle of the present invention is as follows: During operation, the staff turns on the device by operating the control panel 13, and the unloading device evenly places the car buttons on the conveyor belt 11. The unloading device unloads once each time the rotating shaft of the conveyor belt 11 rotates one circle; The operation of the conveyor belt 11 drives its rotating shaft to rotate. Under the joint action of the first bevel gear 261, the second bevel gear 27 and the second rotating shaft 26, the first rotating shaft 24 rotates synchronously, thereby driving the dial 25 to rotate. Every time the dial 25 rotates one circle, the cylindrical pin 251 drives the groove wheel 23 to rotate a specific angle (the angle is equal to the angle between the axes of two adjacent laser marking machines), thereby realizing the intermittent rotation of the mounting plate 22. By setting the transmission component, the conveyor belt 11 and the rotating component are more coordinated, which is conducive to improving work efficiency, and the rotating component does not need to be driven by an additional driving device, thereby reducing equipment costs; When the mounting plate 22 rotates, the clamping assembly is driven to rotate. When the clamping assembly rotates to the top of the conveyor belt 11, the electric push rod 33 is extended, and the electric push rod 33 is extended to push the extrusion plate 34, thereby pushing the lifting rod 32 downward under the transmission of the spring 36, so that the bottom end of the lifting rod 32 extends into the interior of the car button. When the rotating ring 3211 contacts the rotating sleeve 41, the lifting rod 32 cannot move downward any further, and the electric push rod 33 pushes the extrusion plate 34 downward and squeezes the spring 36, so that the connecting rod 341 opens the inner support rod 322, so that the rubber ball 3221 abuts against the inner wall of the car button to fix the car button. By fixing the button from the inside, the button surface is prevented from being damaged, and the defective rate of the product is reduced. In addition, the downward movement of the lifting rod and the expansion of the inner support rod are both realized by the electric push rod, and multiple driving devices are not required, which reduces the production cost of the equipment, simplifies the clamping steps, and improves the work efficiency. After the clamping assembly fixes the car button, when the mounting plate 22 rotates again, the clamping assembly drives the car button to rotate together. When the clamping assembly contacts the arc-shaped rack 45, the car button rotates to the position of the first laser marking machine 15 for the first marking. Then the clamping assembly continues to rotate with the mounting plate 22. At the same time, under the meshing action of the arc-shaped rack 45 and the column gear 42, the clamping assembly drives the car button to rotate and adjust the angle. When the clamping assembly rotates to the position of the next laser marking machine 15, it is marked again. By setting the angle adjustment assembly, the car button automatically rotates to adjust the angle when moving to the next laser marking machine 15. When the car button rotates to the next laser marking machine 15, it can be directly marked without manual adjustment of the angle of the car button, and the work efficiency is high. When the car button rotates to the top of the discharge chute 12, the electric push rod 33 shortens to make the extrusion plate 34 move upward relative to the lifting rod 32, so that the inner support rod 322 is retracted, and the rubber ball 3221 is separated from the car button so that the car button falls into the discharge chute 12 under the action of gravity. After the spring 36 returns to its original shape, the electric push rod 33 continues to shorten to drive the lifting rod 32 to return to its initial height. No additional unloading equipment is required, and the unloading operation and the marking work are carried out in coordination and synchronization, which is conducive to improving work efficiency. The marking work of the automobile button in the present invention is completed in one step from conveying, clamping, multi-angle marking to unloading, and the components cooperate with each other and operate simultaneously, which greatly improves the work efficiency and reduces the production cost of the equipment.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
