[0015] As a further embodiment of this utility model: the conveyor belt is provided with ribs distributed at equal intervals, and an auxiliary centering mechanism is installed on the platform. The auxiliary centering mechanism includes a mounting frame, which is fixed on the platform. A slide is slidably connected to the inner wall of the mounting frame along the conveying direction of the conveyor belt. A mounting seat is installed at one end of the slide. A baffle that penetrates the mounting seat is slidably connected to the inner wall of the mounting seat. A roller is installed at the bottom of the baffle via a shaft. The baffle and the mounting seat are connected by a first spring, and the slide and the mounting frame are connected by a second spring. A U-shaped frame is installed at the top of the baffle. The U-shaped frame has an inverted U-shaped structure. A guide rod is installed on the mounting frame. The guide rod is located on the movement path of the U-shaped frame, and the height of the guide rod gradually increases along the conveying direction of the conveyor belt.

[0016] A guide frame is installed on the platform, and a T-shaped frame is slidably connected to the inner wall of the guide frame. Two adjacent T-shaped frames are equipped with linearly distributed side wheels via shafts. The T-shaped frames and the guide frame are connected by a third spring.

The other end of the elastic rope is connected to the extension bracket of the mounting base after passing through the fixed pulley.

[0017] The bottom height of both the rollers and the T-shaped frame is higher than the top height of the ribs.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. By setting up a conveyor belt, aluminum profiles can be automatically transported. The internal servo motor can start and stop as needed to align the aluminum profiles with the laser emitter, thus enabling precise marking of the aluminum profiles. The set slide rails and slip rings can drive the machine body and machine head to slide up and down by moving the slip rings up and down, thereby adapting to aluminum profiles of different specifications. The cover plate fixed by bolts can not only block dust, but also facilitate the maintenance of the equipment.

[0020] 2. By setting up a camera, the area below the laser emitter can be filmed, and the target area of ​​the laser emitter can be positioned. The anti-slip pads and grooves on the working surface can effectively prevent the control computer from slipping. The control computer can be used to control the marking machine as a whole.

[0021] 3. By setting a temperature probe, the temperature of the aluminum profile being processed can be measured. Then, the data is transmitted to the main control board inside the machine through wires. Finally, the marking machine continues to run through manual operation of the control computer.

[0022] 4. By setting an alarm, the alarm can be activated when the mainboard inside the device senses that the temperature is too high or when the temperature probe senses that the temperature of the aluminum profile is too high, thereby improving the safety of the device.

[0023] 5. By setting up a feeding plate, the aluminum profiles conveyed by the conveyor belt can be transferred to the storage box, which makes it easier to store the marked aluminum profiles. By setting up casters on the storage box, the marked aluminum profiles can be transported by moving the storage box.

[0024] 6. By incorporating a body and a cooling fan, the internal components can be effectively cooled, preventing the laser emission components from overheating.

[0025] 7. By setting a base, the entire device can be supported, and the rubber pad at the bottom of the base can effectively prevent the device from slipping during operation.

[0026] 8. By setting up an auxiliary centering mechanism, when the product to be marked is transported by the conveyor belt, the baffle is located on the conveyor path and contacts the product to be marked. As the conveyor belt transports the product, the baffle is squeezed by the ribs, causing the mounting base and the slide to slide synchronously along the conveyor belt direction. During this process, the elastic rope, guided by the fixed pulley, pulls the T-shaped frame towards the product to be marked. The T-shaped frames on both sides move synchronously, pushing the product to be marked to the center position, completing the auxiliary centering and improving the accuracy of the subsequent marking position. As the conveyor belt continues to transport the product, the U-shaped frame moves to the guide rod. Based on the relative motion, one end of the guide rod is inserted into the U-shaped frame, and as the movement continues, the U-shaped frame is continuously lifted by the guide rod until the bottom height of the baffle is raised above the product to be marked, so as to facilitate the continued transport of the product to be marked and achieve the purpose of avoidance. The conveyor belt transports the product to be marked to the marking position, and the other structures are reset based on the rebound force of each spring. The entire process achieves automatic centering based on the conveyor belt transport, without the need for an additional power source. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0035] Example 1

[0036] A laser marking device suitable for marking aluminum profiles, such as Figure 1-3 As shown, the device includes a platform 1. A large groove is provided on the right side of the platform 1, and a conveyor belt 2 is fixedly installed in the groove by bolts. An electric motor is fixedly installed on one side of the conveyor belt 2. A column 3 is fixed on the upper surface of the platform 1. Slide rails 4 are provided on the front and rear sides of the column 3. Slip rings 5 ​​are slidably installed on the slide rails 4.

A cover plate 9 is detachably installed above the organic head 10 by bolts.

[0037] In this embodiment, by setting up a conveyor belt 2, aluminum profiles can be automatically conveyed. The servo motor inside can start and stop as needed to align the aluminum profiles with the laser emitter 11, thereby enabling precise marking of the aluminum profiles. The slide rail 4 and slide ring 5 can drive the machine body 7 and machine head 10 to slide up and down by moving the slide ring 5 up and down, thereby adapting to aluminum profiles of different specifications. The cover plate 9, which is fixed by bolts, can block dust and also facilitate the maintenance of the equipment.

The camera 12 is connected to the control computer 18 through a wire.

[0039] By setting up camera 12, the area below the laser emitter 11 can be filmed, and the target area of ​​the laser emitter 11 can be positioned. The anti-slip pads and grooves on the working surface 17 can effectively prevent the control computer 18 from slipping. The control computer 18 can be used to control the marking machine as a whole.

[0040] Specifically, a telescopic rod 16 is rotatably mounted on one side of the conveyor belt 2 on the platform 1. A fixed rod 15 is provided on the telescopic rod 16. A temperature probe 13 is fixedly installed at the other end of the fixed rod 15. A wire 14 is connected to the top of the temperature probe 13. The other end of the wire 14 is connected to the main control board inside the machine body 7.

[0041] By setting a temperature probe 13, the temperature of the aluminum profile being processed can be measured. Then, the data is transmitted to the main control board inside the machine body 7 via a wire 14. Finally, the marking machine continues to run by manually operating the control computer 18.

[0042] Specifically, an alarm 20 is fixedly installed on one side of the tabletop 1. The alarm 20 has a loudspeaker inside, an LED light fixedly installed on its top, and a red transparent shell on the outside.

[0043] By setting the alarm 20, the alarm 20 can be activated when the main board inside the body 7 senses that the temperature is too high or the temperature probe 13 senses that the temperature of the aluminum profile is too high, thereby improving the safety of the device.

[0044] Specifically, a feeding plate 21 is rotatably mounted on the platform 1 at the output position of the conveyor belt 2, and a storage box 22 is provided behind the platform 1. Universal wheels are provided under the storage box 22 to facilitate its movement.

[0045] By setting up the feeding plate 21, the aluminum profiles conveyed by the conveyor belt 2 can be transferred to the storage box 22, which makes it easier to store the marked aluminum profiles. By setting up the universal wheels of the storage box 22, the marked aluminum profiles can be transported by moving the storage box 22.

[0046] Specifically, a heat dissipation hole 19 is provided on one side of the body 7, and a cooling fan is installed inside the heat dissipation hole 19.

[0047] By incorporating the main body 7 and a cooling fan, the devices inside the main body 7 can be effectively cooled, preventing the laser emission components from overheating.

[0048] Specifically, a base 23 is provided below the tabletop 1, and a rubber pad is provided at the bottom of the base 23.

[0049] By setting the base 23, the entire device can be supported, and the rubber pad at the bottom of the base 23 can effectively prevent the device from slipping during operation.

[0050] Working principle: When using this device, first turn on the control computer 18, then the required aluminum profile is transported to the working position of the laser emitter 11 by the conveyor belt 2. Adjust the height of the slip ring 5, and use the camera 12 to assist in positioning the aluminum profile. Then rotate the telescopic rod 16 to align the probe of the temperature probe 13 with the aluminum profile to monitor the temperature of the aluminum profile. At this time, turn on the laser emitter 11 to start the operation. After the operation is completed, the finished aluminum profile is dropped into the storage box 22 by the feeding plate 21 through the conveyor belt 2. At the same time, the conveyor belt 2 will also transport new aluminum profiles to the working surface of the laser emitter 11 for the next operation.

[0051] Example 2

[0052] A laser marking device suitable for marking aluminum profiles, such as Figure 4 , Figure 5 As shown, in order to quickly position the product before marking, this embodiment makes the following improvements based on embodiment 1: ribs 26 are provided on the conveyor belt 2 at equal intervals; an auxiliary centering mechanism is installed on the platform 1; the auxiliary centering mechanism includes a mounting frame 24, which is fixed on the platform 1; a slide 34 is slidably connected to the inner wall of the mounting frame 24 along the conveying direction of the conveyor belt 2; a mounting seat 38 is installed at one end of the slide 34; a baffle 31 is slidably connected to the inner wall of the mounting seat 38, penetrating the mounting seat 38; a roller 32 is installed at the bottom of the baffle 31 via a shaft; the baffle 31 and the mounting seat 38 are connected by a first spring 30; the slide 34 and the mounting frame 24 are connected by a second spring 35; a U-shaped frame 37 is installed at the top of the baffle 31, the U-shaped frame 37 has an inverted U-shaped structure; a guide rod 36 is installed on the mounting frame 24; the guide rod 36 is located on the movement path of the U-shaped frame 37; and the height of the guide rod 36 gradually increases along the conveying direction of the conveyor belt 2.

[0053] A guide frame is installed on the platform 1. A T-shaped frame 28 is slidably connected to the inner wall of the guide frame. Two adjacent T-shaped frames 28 are equipped with linearly distributed side wheels 27 via shafts. The T-shaped frames 28 and the guide frame are connected by a third spring 33. A fixed pulley 25 is installed on the guide frame via a shaft. An elastic rope 29 is installed at one end of the T-shaped frame 28. An extension bracket is installed on the side of the mounting base 38. The other end of the elastic rope 29 is connected to the extension bracket of the mounting base 38 after passing through the fixed pulley 25.

[0054] The bottom height of both roller 32 and T-shaped frame 28 is higher than the top height of rib 26; and the bottom height of roller 32 and T-shaped frame 28 should be lower than the top height of the product to be marked.

[0055] By setting up an auxiliary centering mechanism, when the product to be marked is conveyed by the conveyor belt 2, since the baffle 31 is located on the conveying path, the baffle 31 contacts the product to be marked. As the conveyor belt 2 conveys, the baffle 31 is squeezed by the ribs 26, which in turn causes the mounting base 38 and the slide 34 to slide synchronously along the conveying direction of the conveyor belt 2. During this process, the elastic rope 29, guided by the fixed pulley 25, pulls the T-shaped frame 28 towards the product to be marked. The T-shaped frames 28 on both sides move synchronously, thus pushing the product to be marked to the middle position, completing the auxiliary centering, and improving the subsequent marking efficiency. Position accuracy: As the conveyor belt 2 continues to transport the product, the U-shaped frame 37 moves to the guide rod 36. Based on the relative motion, one end of the guide rod 36 is inserted into the U-shaped frame 37. As the movement continues, the U-shaped frame 37 is continuously lifted by the guide rod 36 until the bottom height of the baffle 31 is raised above the product to be marked, so as to facilitate the continued transport of the product to be marked and achieve the purpose of avoidance. The conveyor belt 2 transports the product to be marked to the marking position, and other structures are reset based on the rebound force of each spring. The whole process is automatically centered based on the transport of the conveyor belt 2, without the need for an additional power source.

[0056] For the parts of this utility model not disclosed in detail, those skilled in the art can ensure the smooth implementation of the solution of this utility model based on common sense, normal thinking logic and existing technology.

[0057] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
