Description

Technical Field

[0001] This utility model relates to the field of remote control processing technology, and in particular to an online laser engraving QR code device for remote control PCB boards. Background Technology

[0002] In the manufacturing process of electronic products such as remote controls, in order to achieve quality traceability throughout the product's entire lifecycle, it is usually necessary to laser-engrave QR codes on the PCB board as unique identifiers. Currently, the common production method used in the industry is: operators manually place PCB panels composed of multiple small boards onto a positioning fixture, and then start a laser marking machine to complete the laser engraving operation.

[0003] However, for large PCB panels whose size exceeds the single processing range of the laser engraving machine (i.e., the field lens range), manual secondary material handling is required to transfer them to another machine to complete the remaining laser engraving. This process not only severely restricts production efficiency but also increases labor costs and equipment investment. Secondly, operators need to be close to the laser engraving area, and the harmful dust generated during the operation directly threatens their respiratory health, posing a significant safety hazard.

[0004] Therefore, in order to further improve the efficiency and safety of laser engraving on existing PCB boards, we propose a remote-controlled online laser engraving QR code device for PCB boards. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the need for manual secondary material handling for large-sized PCB panels whose dimensions exceed the single-processing range of laser engraving machines. This invention proposes an online laser engraving QR code device for remote control PCB boards.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a remote control PCB board online laser engraving QR code device, including a machine base, and a laser engraving mechanism is set on the top of the machine base; A vertical plate and a platform are provided above the machine tool, and a conveying assembly is provided between the vertical plate and the platform. The conveying assembly is located below the laser engraving mechanism. The conveying assembly is further provided with a primary stop assembly and a secondary stop assembly, which are used for secondary laser engraving positioning of the PCB panel.

[0007] Furthermore, the conveying assembly includes two guide rods fixedly installed between the upright plate and the platform; And two lead screws that are rotatably connected between the vertical plate and the platform; Two profile bodies are provided between the guide rod and the lead screw. One profile body is threaded to the lead screw, and the other profile body passes through the lead screw and is fixedly connected to the guide rod by a locking member.

[0008] Furthermore, two pulleys are rotatably connected to the inner side of the profile body, and a conveyor belt is rotatably connected between the two pulleys. The PCB panel is placed above the two conveyor belts, and a motor is fixedly installed on the outer side of the profile body and fixedly connected to one of the pulleys.

[0009] Furthermore, a positioning bracket is fixedly installed above the profile body that is threadedly connected to the lead screw, and a positioning cylinder is fixedly installed above the positioning bracket, with a clamping block installed on the shaft end of the positioning cylinder.

[0010] Furthermore, the primary stop assembly and the secondary stop assembly have the same structure; The primary stop assembly includes a fixed base and a first bracket; A stop cylinder is fixedly installed on the side of the fixed base, and a stop block is fixedly installed on the shaft end of the stop cylinder. A sensor is also fixedly installed on the first bracket.

[0011] Furthermore, a second bracket is fixedly installed on the rear side of the profile body along the conveying direction, and a discharge sensor is fixedly installed on the second bracket.

[0012] Furthermore, the laser engraving mechanism includes a lifting module and a laser engraving machine, with the laser engraving machine fixedly mounted on the slide of the lifting module.

[0013] Furthermore, the lifting module is configured as a lead screw module.

[0014] This invention proposes an online laser engraving device for QR codes on remote control PCB boards. The advantages are as follows: By setting up primary and secondary stop components, this invention achieves partitioned secondary positioning of the PCB panel. This design divides large-size panels into two independent processing areas, allowing the laser engraving mechanism to complete the QR code laser engraving operation of the entire panel in steps. This solution effectively solves the problem of incomplete laser engraving coverage and the need for manual intervention caused by excessively large panel sizes, significantly improving automation, work efficiency, and operational safety.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-4 As an embodiment of this utility model, it discloses an online laser engraving QR code device for remote control PCB boards. Specifically, the device includes a machine base 1, and a laser engraving mechanism 2 is provided above the machine base 1. The laser engraving mechanism 2 is used to laser mark QR codes on the upper side of the PCB panel 8. In this embodiment, the PCB panel 8 is composed of multiple independent small PCB boards for processing together, and then split into multiple PCB single boards. Preferably, in this embodiment, the PCB panel 8 is composed of ten small boards. A vertical plate 3 and a platform 4 are provided above the machine base 1. A conveying assembly 5 is provided between the vertical plate 3 and the platform 4. The conveying assembly 5 is located below the laser engraving mechanism 2. The conveying assembly 5 is further provided with a primary stop assembly 6 and a secondary stop assembly 7, which are used to perform secondary laser engraving positioning on the PCB panel 8.

[0019] Specifically, this invention achieves partitioned secondary positioning of the PCB panel 8 by setting a primary stop component 6 and a secondary stop component 7. This design divides the large-size panel into two independent processing areas, allowing the laser engraving mechanism 2 to complete the QR code laser engraving operation of the entire panel in steps. This solution effectively solves the problem of incomplete laser engraving coverage and the need for manual intervention caused by the large size of the panel, significantly improving the level of automation, work efficiency, and operational safety.

[0020] In some embodiments, the conveying assembly 5 of the present invention includes two guide rods 51 fixedly installed between the upright plate 3 and the platform 4; And two lead screws 52 that are rotatably connected between the vertical plate 3 and the platform 4; Two profile bodies 53 are provided between the guide rod 51 and the lead screw 52. One profile body 53 is threadedly connected to the lead screw 52, ​​and the other profile body 53 passes through the lead screw 52 and is fixedly connected to the guide rod 51 by a locking member.

[0021] Specifically, in this embodiment, the locking component can be equipped with a bolt, which is threadedly connected to the outside of another profile 53 and abuts against the guide rod 51 to position the profile 53. Since one of the profiles 53 and the lead screw are threadedly connected, in this embodiment, the spacing between the two profiles 53 can be adaptively adjusted by synchronously driving the lead screws 52 on both sides, thereby meeting the conveying requirements of PCB panels 8 of different widths.

[0022] Furthermore, in this embodiment, in order to achieve synchronous driving of the two lead screws 52, a pulley can be fixedly installed at the end of each of the two lead screws 52, and the two pulleys are driven by a synchronous belt. In this way, when one lead screw 52 is rotated, the other lead screw 52 will also rotate synchronously. In other embodiments, the two lead screws 52 can also be driven synchronously by a sprocket and chain drive. This method is a conventional transmission method for those skilled in the art and will not be described in detail here.

[0023] Furthermore, in this embodiment of the invention, two pulleys 54 are rotatably connected to the inner side of the profile body 53, and a conveyor belt 55 is rotatably connected between the two pulleys 54. The PCB panel 8 is placed above the two conveyor belts 55. A motor (not shown) is fixedly installed on the outer side of the profile body 53 and fixedly connected to one of the pulleys 54. That is, in order to adapt to the positioning of the two sides of the PCB panel 8, it is necessary to automatically move the PCB panel 8. In this embodiment, by using a motor to drive one pulley 54 to rotate, the conveyor belt 55 can be driven to rotate, thus realizing the smooth forward movement of the PCB panel 8 on the two conveyor belts 55.

[0024] Of course, in this embodiment, the conveyor belt 55 can be configured as a synchronous belt, which is sleeved between two pulleys 54 of the same profile body 53. In this way, when the motor drives the pulleys 54 to rotate, the rotation drive of the conveyor belt 55 is completed.

[0025] Based on the above embodiments, in this embodiment, a positioning bracket 56 is fixedly installed above the profile body 53 that is threadedly connected to the lead screw 52, ​​and a positioning cylinder 57 is fixedly installed above the positioning bracket 56. A clamping block 58 is installed on the shaft end of the positioning cylinder 57.

[0026] The clamping block 58 is used to clamp and fix the PCB panel 8 to improve the stability of the laser engraving operation. Specifically, when the conveyor belt 55 moves the PCB panel 8 to the primary stop assembly 6 and is located below the laser engraving mechanism 2, the positioning cylinder 57 is activated to drive the clamping block 58 to abut against the side of the PCB panel 8, thereby achieving the clamping and fixing of the PCB panel 8.

[0027] Preferably, the positioning bracket 56 in this utility model can be locked and fixed by the profile slider nut and the profile body 53, that is, the slider nut is slidably connected in the groove of the profile body 53, and the positioning bracket 56 is locked to the slider nut by bolts or other fasteners. This design is to realize the left and right position adjustment of the clamping block 58 so as to make the clamping position suitable for use.

[0028] In some embodiments, the primary stop assembly 6 and the secondary stop assembly 7 described in this utility model have the same structure. The specific structure of the primary stop assembly 6 will be described below, and the structure of the secondary stop assembly 7 will not be described again. The primary stop assembly 6 includes a fixed base 61 and a first bracket 62; A stop cylinder 63 is fixedly installed on the side of the fixed base 61, and a stop block 64 is fixedly installed on the shaft end of the stop cylinder 63. A sensor 65 is also fixedly installed on the first bracket 62.

[0029] Specifically, the sensor 65 described in this embodiment can be set as a photoelectric sensor, which is used to detect the arrival signal of the PCB panel 8. When the PCB panel 8 is transported to the sensor 65 of the primary stop assembly 6, the stop cylinder 63 is activated to stop and position the side of the PCB panel 8 through the stop block 64.

[0030] In a further embodiment, a second bracket 66 is fixedly installed on the rear side of the profile body 53 along the conveying direction. A discharge sensor 67 is fixedly installed on the second bracket 66. Similarly, the discharge sensor 67 in this embodiment is also set as a photoelectric sensor, which is used to confirm the status of the PCB panel 8 after it is output, so as to facilitate the subsequent board loading operation and ensure the reliability and convenience of the operation in the online assembly line mode.

[0031] Of course, the first bracket 62 and the second bracket 66 described in this embodiment can also be movably connected to the profile body 53 via a slider nut, so as to facilitate convenient adjustment of their positions. This method is a conventional method for those skilled in the art and will not be elaborated here.

[0032] In addition, a control unit, such as a PLC, should be used in this invention to connect the sensors and motors, so as to facilitate the collection of signals and the control of the electrical components.

[0033] In some embodiments, the laser engraving mechanism 2 of this utility model includes a lifting module 21 and a laser engraving machine 22. The laser engraving machine 22 is fixedly installed on the slide of the lifting module 21. Optionally, in this embodiment, the lifting module 21 is set as a lead screw module. The lead screw module is manually controlled and is used to adaptively adjust the height of the laser engraving machine 22. In this embodiment, the laser engraving machine 22 can be a laser marking and engraving machine in the prior art, which will not be elaborated here.

[0034] Equipment working process: After the equipment is turned on, the conveyor belt 55 starts and requests the board to be placed on the board. When the 10-piece PCB panel 8 is conveyed to the primary stop assembly 6, it is intercepted and stopped. When the sensor 65 of the primary stop assembly 6 detects the PCB, the side positioning cylinder 57 extends, so that the primary stop assembly 6 is positioned to the side. The laser engraving machine 22 is started to laser engrave PCBs 1 to 5. When the laser engraving is completed, the laser engraving machine 22 gives a completion signal, the positioning cylinder 57 retracts, and the stop cylinder 63 of the primary stop assembly 6 is lowered. Then, the PCB panel 8 is conveyed to the secondary stop assembly 7 and stops. At the same time, the sensor 65 of the secondary stop assembly 7 detects the PCB panel 8. At this time, the side positioning cylinder 57 extends again to complete the edge positioning of the PCB panel 8. Since the distance between the primary stop assembly 6 and the secondary stop assembly 7 is exactly the same as that of PCBs 1# to 5#, the laser engraving machine 22 is restarted to laser engrave the corresponding positions of the QR codes on PCBs 6# to 10#. When the laser engraving is completed, the laser engraving machine 22 gives a completion signal, the positioning cylinder 57 retracts, and the secondary stop assembly 7 is lowered. Finally, the PCB panel 8 is conveyed to the output position. When the output sensor 67 detects the PCB, the conveyor belt 55 stops. When it receives the output signal from the subsequent board receiving machine, the conveyor belt 55 starts and conveys the 10 laser-engraved PCB panels out. The above process is repeated to realize online automatic laser engraving of PCB panels.

[0035] 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. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
