At present, in the production and processing of electronic cigarette microphones, it is necessary to laser engrave or engrave some anti-counterfeiting marks on the surface to complete the production identification. The traditional production steps are all manual, placing the microphone under the laser head of the laser marking machine, and replacing the microphone after laser engraving. This method is not only inefficient, but also increases labor costs.

Therefore, the above terms should not be understood as limiting the present invention.

[0028] In the description of the utility model, if there is a word description such as "several", it means one or more, and the meaning of "more" is two or more. Greater than, less than, and more than are understood to exclude the number itself, and above, below, and within are understood to include the number itself. If there is a description of the first, second, and third, it is only used to distinguish the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0029] The following is combined with Figure 1-8 , an embodiment of a microphone laser marking machine of the utility model is further described in detail.

[0030] A microphone laser marking machine, such as Figures 1 to 4As shown, it includes a chassis 1 and a workbench 11 arranged on the chassis 1, and a clamping and positioning device 2 is slidably connected to the workbench 11. The clamping and positioning device 2 includes a mounting base 21, a plurality of driving components 22 vertically connected to the mounting base 21, a clamping plate 23 drivingly connected to the plurality of driving components 22, and a tray 24 connected to the clamping plate 23 by snapping. The two ends of the clamping plate 23 are bent upward to form a limiting clamping claw 231, and a hollow structure is set between two adjacent limiting clamping claws 231. The cross section of the clamping plate 23 is an I-shaped structure, and a U-shaped slide groove 233 is opened near the middle position, and the U-shaped slide groove 233 is connected to the driving component 22; the driving component 22 includes a first driving cylinder 221, a first lifting slide 222, a second driving cylinder 223 and a second lifting slide 224. The first driving cylinder 221 is provided with a first lifting slide 222, a second driving cylinder 223 and a second lifting slide 224. One side of the driving cylinder 221 is fixedly connected to the mounting base 21, and the other side is slidably connected to the first lifting slide 222, and the output shaft of the first driving cylinder 221 is engaged with one end of the first lifting slide 222 and abuts against the clamping plate 23; one side of the second driving cylinder 223 is fixedly connected to the mounting base 21, and the other side is slidably connected to the second lifting slide 224, and the output shaft of the second driving cylinder 223 is engaged with one end of the second lifting slide 224; a blocking plate 225 is fixedly connected to the side of the second lifting slide 224 facing away from the second driving cylinder 223, and a blocking block 226 for engaging and positioning the tray 24 is provided on the blocking plate 225, and the blocking block 226 is L-shaped, and one end of it is connected to the blocking plate 225, and the other end passes through the hollow structure on the clamping plate 23 and extends to the tray 24.

[0031] Specifically, when clamping and positioning the microphone, the tray 24 on the clamping and positioning device 2 is removed, and multiple microphones are placed in the tray 24, with the side of the microphone to be marked facing upward, and the tray 24 is placed again on the clamping plate 23, and the driving component 22 is used to drive the limiting claws 231 at both ends of the clamping plate 23 to clamp and position the tray 24. At the same time, the output shaft of the first lifting cylinder extends upward and drives the first lifting slide 222 to slide upward. Since the first lifting slide 222 is locked with the U-shaped slide groove 233 on the clamping plate 23, the first lifting slide 222 is locked with the U-shaped slide groove 233 on the clamping plate 23. Therefore, when the first lifting slide 222 is pushed upward, the clamping plate 23 also rises synchronously, and the second driving cylinder 223 synchronously drives the second lifting slide 224 to rise, so that the blocking plate 225 and the blocking block 226 arranged on the second lifting cylinder extend upward until the blocking block 226 passes through the hollow structure on the clamping plate 23 and is clamped on the tray 24, thereby completing further limiting the tray 24; thereby preventing the clamping and positioning device 2 from causing the microphone in the tray 24 to shift during the movement, resulting in poor marking effect.

[0032] In addition, it is worth noting that in order to better automatically adjust the marking direction and distance, an operating mechanism is provided on the workbench 11. The operating mechanism includes an operating button and a controller. The controller is electrically connected to the clamping positioning mechanism and the laser marking mechanism, and the operating button is used to control the transportation and start and stop of the entire equipment, thereby realizing automatic and intelligent operation, reducing labor costs, and improving production efficiency.

[0033] In this embodiment, if Figure 5 , 6 As shown, a plurality of positioning grooves 241 for limiting materials are arranged in an array on both sides of the tray 24, and the plurality of positioning grooves 241 are interconnected. Positioning holes 242 are provided on all sides of the tray 24 surrounding the positioning grooves 241; arc-shaped grooves 243 for facilitating material removal are also provided on both sides of the positioning grooves 241 near the edges, and the positioning grooves 241 adopt one of circular, rectangular or square structures.

[0034] Specifically, positioning grooves 241 are provided on both sides of the tray 24 for faster and better loading. A single microphone can be limited in the positioning groove 241, and arc-shaped grooves 243 are provided on both sides of the positioning groove 241 close to the edge, and the positioning grooves 241 are connected to each other, so as to make it more convenient to take the microphone. At the same time, in order to adapt to the shape of the microphone and better limit the microphone, the shape of the positioning groove 241 can be designed according to the actual product shape. In addition, in order to better fix the tray 24 on the clamping plate 23, the positioning hole 242 provided on the tray 24 is adapted to the positioning block 232 provided on the clamping plate 23, and a clearance fit is adopted between the positioning block 232 and the positioning hole 242, so that it can be more fixedly and stably installed on the clamping plate 23 to prevent deviation during the marking process.

[0035] In this embodiment, Figure 7 As shown, a belt transmission mechanism 3 for driving the clamping and positioning device 2 to slide is provided in the workbench 11, and the belt transmission mechanism 3 includes a fixed frame 31, a pulley 32, a synchronous belt 33 and a transmission shaft 34. The pulley 32 is provided with multiple, and the multiple pulleys 32 are rotatably connected to both sides of the fixed frame 31, and the pulleys 32 are connected through the transmission shaft 34, and the synchronous belt 33 is sleeved on the outer surface of the pulley 32.

[0036] Specifically, the direction in which the belt transmission mechanism 3 is set is parallel to the clamping and positioning device 2, so that the clamping and positioning device 2 can be moved along the transmission direction of the synchronous belt 33. The belt transmission mechanism 3 uses the transmission principle of the pulley 32 for transmission. During the transmission process, an external drive motor is used to drive the transmission shaft 34 to rotate, so that the transmission shaft 34 drives the pulley 32 and the synchronous belt 33 to rotate synchronously to achieve the transportation purpose. In the utility model, in addition to using a belt transmission mechanism, other structures with transmission functions can also be used, including but not limited to traditional rack and pinion transmission, worm gear transmission, screw transmission, etc.

[0037] In this embodiment, if Figure 8 As shown, a laser marking device 4 is provided on one side of the clamping and positioning device 2 on the workbench 11, and at least two laser marking devices 4 are provided. The two laser marking devices 4 are respectively connected to the workbench 11 in a horizontal and vertical direction, and a translation mechanism 5 is provided between the bottom ends of the two laser marking devices 4 and the workbench 11; the laser marking device 4 includes a mounting bracket 41, a laser 42 and a marking head 43, the mounting bracket 41 is slidably connected to the translation mechanism 5, and one side of the mounting bracket 41 is connected to an operation display screen 6; the laser 42 and the marking head 43 are detachably connected, and a lifting mechanism 7 is slidably connected between the laser 42 and the mounting bracket 41.

[0038] Specifically, the marking principle of the laser marking device 4 is a well-known technology, so it will not be described in detail here. The purpose of arranging the laser marking device 4 in the horizontal and longitudinal directions of the workbench 11 is to be able to simultaneously satisfy the marking information of the material on different surfaces, so that the marking can be carried out simultaneously in different directions to improve the marking efficiency. For this reason, at least two laser marking devices 4 are provided, and the number of laser marking devices 4 can be set according to actual conditions based on production needs; in addition, the translation mechanism 5 arranged at the bottom of the laser marking device 4 can enable it to move forward, backward, left and right on the workbench 11, which is convenient for adjusting the marking position, and can also adjust the marking direction of the laser marking mechanism according to the actual marking situation. The translation mechanism 5 on the longitudinally arranged laser marking device 4 adopts the screw transmission principle. The guide plate is driven to slide by a screw rod, thereby driving the laser marking device 4 to slide, and two translation mechanisms 5 are provided at the same time. The two translation mechanisms 5 are vertically arranged up and down, and the other translation mechanism 5 is slidably connected, thereby controlling the direction of the laser cutting device on the X-axis and the Y-axis; by the same token, the scheme of the horizontally arranged laser marking device 4 is the same.

[0039] In addition, the laser 42 and the laser marking head 43 in the laser marking device 4 are detachably connected, specifically, one of a threaded connection and a snap-on connection, and the laser 42 is fixed on the mounting bracket 41, and is slid and lifted by the lifting mechanism 7. The lifting mechanism 7 and the translation mechanism 5 have the same structure, both of which use the screw transmission principle to lift and lower the laser marking device 4. This allows the laser marking device 4 to quickly align with the target to be marked, and adjust the position according to the marking requirements, so that the marking effect is improved.

[0040] The working principle of this utility model:

[0041] When marking the microphone, the microphone is placed in the positioning groove 241 on the tray 24 in sequence, with the side to be marked facing upward, and then the tray 24 is placed on the clamping plate 23, and the limiting clamping claws 231 at both ends of the clamping claws automatically clamp the tray 24 to fix it on the clamping plate 23; at the same time, the clamping plate 23 can adjust the height of the tray 24 up and down under the action of the first driving cylinder 221 driving the first lifting slide 222, so as to adjust the distance between the tray 24 and the laser marking device 4, which is convenient for controlling the marking efficiency; at the same time, under the action of the second driving cylinder 223 driving the second lifting slide 224, the blocking plate 225 passes through the hollow structure on the clamping plate 23 upward through the blocking block 226 and abuts against The tray 24 is fixed firmly on the clamping plate 23 to prevent displacement. In addition, the clamping and positioning device 2 can be translated by the belt conveyor mechanism 3 at the bottom, which is convenient for adjusting the marking position and quickly loading and unloading materials. The laser marking device 4 is provided in both the horizontal and vertical directions, which can simultaneously mark both sides of the microphone head to meet different marking requirements. A translation mechanism 5 and a lifting mechanism 7 are provided on the laser marking device 4, which can adjust the marking direction of the laser marking device 4 from multiple latitudes, thereby improving its marking effect and making it more applicable. After the marking is completed, the clamping plate 23 releases the tray 24 to facilitate the operator to load and unload materials. The above steps are repeated to complete continuous production.

[0042] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
