[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] In existing technologies, traditional positioning and packaging devices can often only operate on PCBs of a single specification or a few specifications. When dealing with PCBs of different specifications, it is necessary to frequently change tooling fixtures and adjust equipment parameters, which increases production preparation time and production costs, and also reduces the production efficiency of PCBs. This results in poor adaptability of the equipment to different specifications of PCBs. In addition, it is difficult to guarantee high-precision positioning of PCBs of different specifications during the packaging process, thereby affecting the packaging quality of PCBs and the performance stability of electronic products.

[0020] In view of this, the present invention provides an integrated adaptive positioning and packaging device for multi-specification PCB boards. Through the cooperation of a base, an X-axis linear motor, a Y-axis linear motor, a recessed platform, a conveyor assembly, a positioning assembly, and a dispensing and packaging assembly, the PCB boards are transported using adjustable-pitch belt conveyors. A positioning method combining physical positioning and visual recognition is used to achieve high-precision positioning and recognition of the PCB boards. This allows the dispensing and packaging assembly to perform precise dispensing and packaging operations on the PCB boards. Furthermore, the spacing between the two belt conveyors can be quickly adjusted according to the specifications of the PCB boards to adapt to the positioning and packaging requirements of different PCB specifications, meeting the needs of large-scale and diversified production. Moreover, visual recognition technology is used to accurately acquire the coordinate information of key positions on the PCB boards, effectively improving the packaging quality of the PCB boards and the performance stability of electronic products, enhancing adaptability to different PCB board specifications, production efficiency, and product quality.

[0021] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process.

[0022] Depend on Figure 1-7 It is known that a multi-specification PCB board adaptive positioning and packaging integrated device includes a base 1, with X-axis linear motors 2 fixedly connected to both sides of the top of the base 1, and Y-axis linear motors 3 fixedly connected to the output ends of the X-axis linear motors 2. A recessed platform 4 is provided on the top of the base 1. The multi-specification PCB board adaptive positioning and packaging integrated device also includes a conveyor line assembly 5, a positioning assembly 6, and a dispensing and packaging assembly 7. The conveyor line assembly 5 is located on the top of the recessed platform 4; the positioning assembly 6 is located on the top of the conveyor line assembly 5; and the dispensing and packaging assembly 7 is located above the conveyor line assembly 5. The conveyor line assembly 5 is adaptively adjusted according to the size of the PCB board, enabling the conveying of PCB boards of various specifications. The positioning assembly 6 performs physical positioning and visual recognition of the conveyed PCB board, and the dispensing and packaging assembly 7 performs dispensing and packaging operations on the positioned PCB board.

[0023] In the specific implementation process, it is worth noting that the base 1 provides stable support and fixation for each component of the PCB board positioning and packaging device. Through the cooperation between the X-axis linear motor 2 and the Y-axis linear motor 3, a flexible two-dimensional planar working area is formed above the conveyor line assembly 5. The Y-axis linear motor 3 is equipped with two movers, which provide precise position adjustment for the vision recognition component 66 and the dispensing and packaging component 7, respectively. It performs visual recognition on the PCB board that has moved to the designated position and performs dispensing and packaging operations on the specific position according to the recognition result. The conveyor line assembly 5 consists of two belt conveyor lines. The two sides of the PCB board are respectively placed on the two belt conveyor lines. The PCB board is transported by the rotation of the belts. It can be adaptively adjusted according to the size of the PCB board by adjusting the distance between the two belt conveyor lines, thereby transporting PCB boards of different specifications. The X-axis linear motor 2, Y-axis linear motor 3, recessed platform 4, conveyor assembly 5, positioning assembly 6, and dispensing and encapsulation assembly 7 work together. An adjustable-pitch belt conveyor transports the PCB board. A combination of physical positioning and visual recognition is used to achieve high-precision positioning and identification of the PCB board. This allows the dispensing and encapsulation assembly 7 to perform precise dispensing and encapsulation operations on the PCB board. The spacing between the two belt conveyors can be quickly adjusted according to the PCB board specifications to adapt to the positioning and encapsulation needs of different PCB sizes, meeting the demands of large-scale and diversified production. Furthermore, visual recognition technology is used to accurately acquire the coordinate information of key positions on the PCB board, effectively improving the encapsulation quality of the PCB board and the performance stability of electronic products. This enhances adaptability to different PCB board specifications, production efficiency, and product quality. The specific models of the X-axis linear motor 2 and Y-axis linear motor 3 are not limited; they only need to meet the usage requirements. Furthermore, the conveyor assembly 5 includes a first belt conveyor 51, a second belt conveyor 52, a first servo motor 53, and an adaptive adjustment component 54. The first belt conveyor 51 is fixedly connected to one side of the top of the recessed platform 4; the second belt conveyor 52 is located on the top side of the recessed platform 4 away from the first belt conveyor 51; two first servo motors 53 are provided, respectively fixedly connected to one end of the first belt conveyor 51 and the second belt conveyor 52; the adaptive adjustment component 54 is located at the bottom of the second belt conveyor 52. Through the cooperation of the first belt conveyor 51 and the second belt conveyor 52, the PCB board is conveyed between the first belt conveyor 51 and the second belt conveyor 52, and the spacing between the first belt conveyor 51 and the second belt conveyor 52 can be flexibly adjusted according to the width of the PCB board via the adaptive adjustment component 54.

[0024] In the specific implementation process, it is worth noting that the first servo motor 53 provides power for the operation of the first belt conveyor 51 and the second belt conveyor 52. The two sides of the PCB board are respectively placed on the conveying surface between the belts and the frame of the first belt conveyor 51 and the second belt conveyor 52. The belts are driven to rotate by the first servo motor 53, and the two first servo motors 53 are synchronously controlled by the control system to ensure that the conveying speed of the first belt conveyor 51 and the second belt conveyor 52 is consistent, so as to realize the conveying of the PCB board and avoid the PCB board from shifting or being damaged during the conveying process. The specific model of the first servo motor 53 is not limited, as long as it meets the usage requirements. Furthermore, the adaptive adjustment component 54 includes a first slide rail 541, a first slide block 542, a bearing seat 543, a threaded screw 544, and a second servo motor 545. Multiple first slide rails 541 are provided, vertically distributed below the second belt conveyor 52, and fixedly connected to the top of the recessed platform 4. The first slide block 542 is slidably connected to the outer wall of the first slide rail 541 and fixedly connected to the bottom of the second belt conveyor 52. Two bearing seats 543 are provided and fixedly connected to the top of the recessed platform 4. The threaded screw 544... Rod 544 is rotatably connected to the inner wall of bearing seat 543, and its outer wall is threadedly connected to the second belt conveyor line 52; the second servo motor 545 is fixedly connected to the outer wall of base 1, and its output end is driven to one end of threaded screw 544; wherein, by controlling the second servo motor 545, the threaded screw 544 is driven to rotate, thereby driving the second belt conveyor line 52 to slide on the first slide rail 541, thereby realizing the adjustment of the distance between the first belt conveyor line 51 and the second belt conveyor line 52 to adapt to PCB boards of different specifications.

[0025] In the specific implementation process, it is worth noting that through the cooperation between the second belt conveyor 52, the first slide rail 541, the first slide block 542, the bearing seat 543, the threaded screw 544, and the second servo motor 545, the second servo motor 545 is controlled to drive the threaded screw 544 to rotate, thereby causing the second belt conveyor 52 to slide along the axial direction of the threaded screw 544 on the first slide rail 541. This allows the spacing between the first belt conveyor 51 and the second belt conveyor 52 to be adjusted according to the width of different PCB boards, ensuring that the two sides of the PCB board can be stably placed on the conveying surfaces of the two belt conveyors. This meets the conveying requirements of different PCB boards and avoids the PCB board falling or shifting during the conveying process, improving the stability and reliability of the conveying. The specific model of the second servo motor 545 is not limited, as long as it meets the usage requirements. Furthermore, a laser rangefinder 546 is fixedly connected to the outer wall of the second belt conveyor 52, and the laser rangefinder 546 is arranged opposite to the first belt conveyor 51.

[0026] In the specific implementation process, it is worth noting that the laser rangefinder 546 is used to sense the distance between the first belt conveyor 51 and the second belt conveyor 52, and feeds this distance information back to the control system. The control system can then automatically control the second servo motor 545 according to the PCB board specifications and the feedback signal from the laser rangefinder 546, thereby adjusting the spacing between the first belt conveyor 51 and the second belt conveyor 52. The specific model of the laser rangefinder 546 is not limited, as long as it meets the usage requirements. Furthermore, the positioning component 6 includes a photoelectric sensor 61, a first servo cylinder 62, a limiting baffle 63, a second servo cylinder 64, a pressing rod 65, and a visual recognition component 66. The photoelectric sensor 61 is fixedly connected to the outer wall of the first belt conveyor 51 near the second belt conveyor 52; the first servo cylinder 62 is fixedly connected to the first belt conveyor 51 on the side of the photoelectric sensor 61 away from the first servo motor 53; the limiting baffle 63 is fixedly connected to the output end of the first servo cylinder 62; two sets of the second servo cylinder 64 are provided and fixedly connected to the first belt conveyor. The outer wall of the first servo cylinder 62 and the second belt conveyor 52 is located away from each other; the pressure rod 65 is fixedly connected to the output end of the second servo cylinder 64; the vision recognition component 66 is set on the outer wall of one output end of the Y-axis linear motor 3; wherein, the position of the conveyed PCB board is sensed by the photoelectric sensor 61, and the control system automatically controls the first servo cylinder 62 and the second servo cylinder 64 according to the sensing signal to physically position the PCB board, and the vision recognition component 66 performs visual recognition on the PCB board to obtain the coordinate information of each key position of the PCB board, providing data support for dispensing and encapsulation operations.

[0027] In the specific implementation process, it is worth noting that the photoelectric sensor 61 is used to sense the conveyed PCB board at a designated position. When the PCB board passes the photoelectric sensor 61, the photoelectric sensor 61 transmits a signal to the control system. Based on this signal, the control system starts the first servo cylinder 62 and stops the first servo motor 53, causing the limit baffle 63 to extend and block the PCB board from continuing to be conveyed forward. At the same time, the control system controls the second servo cylinder 64 to move the pressing rod 65 downward, pressing the PCB board firmly on the conveyor line to prevent it from shifting in subsequent operations. This provides a stable positioning basis for subsequent visual recognition and dispensing encapsulation operations. Multiple second servo cylinders 64 are provided, and the number of second servo cylinders 64 can be flexibly adjusted according to the size information of the PCB board to ensure effective positioning of PCB boards of different specifications. The visual recognition component 66 is used to perform visual recognition scanning on the PCB board to accurately obtain the coordinate information of various key positions on the PCB board, such as solder joints, pins, and chip mounting positions. The specific models of the photoelectric sensor 61, the first servo cylinder 62, and the second servo cylinder 64 are not limited, as long as they meet the usage requirements. Furthermore, the visual recognition component 66 includes a first Z-axis KK module 661, a camera 662, a camera 663, and a coaxial light source 664. The first Z-axis KK module 661 is fixedly connected to the outer wall of the output end of the Y-axis linear motor 3 away from the first belt conveyor 51. The camera 662 is fixedly connected to the top of the outer wall of the output end of the first Z-axis KK module 661. The camera 663 is located at the bottom of the camera 662 and is fixedly connected to the outer wall of the output end of the first Z-axis KK module 661. The coaxial light source 664 is located at the bottom of the camera 663 and is fixedly connected to the outer wall of the output end of the first Z-axis KK module 661. By controlling the movers of the X-axis linear motor 2 and the Y-axis linear motor 3 away from the first belt conveyor 51 and the first Z-axis KK module 661, the camera 662, camera 663, and coaxial light source 664 are moved to a suitable position above the PCB board to acquire images of the PCB board, thereby obtaining the coordinate information of each key position on the PCB board.

[0028] In the specific implementation process, it is worth noting that through the cooperation between the X-axis linear motor 2, Y-axis linear motor 3, first Z-axis KK module 661, camera 662, camera 663, and coaxial light source 664, the position and height of camera 662, camera 663, and coaxial light source 664 can be flexibly adjusted to adapt to the visual recognition needs of PCB boards of different specifications. The coaxial light source 664 provides uniform illumination, which reduces the influence of shadows and reflections when camera 662 and camera 663 acquire PCB board images, improving image clarity and quality. Camera 662 transmits the acquired image data to the control system. The control system analyzes and processes the image through image processing algorithms to accurately calculate the coordinate information of key positions on the PCB board, such as solder joints, pins, and chip mounting positions, so as to guide the dispensing and encapsulation component 7 to perform precise dispensing and encapsulation operations. The specific models of the first Z-axis KK module 661, camera 662, camera 663, and coaxial light source 664 are not limited, as long as they meet the usage requirements. Furthermore, the dispensing and encapsulation assembly 7 includes a dispensing valve 71, a glue supply tube 72, and a dispensing angle adjustment assembly 73.

By controlling the movers of the X-axis linear motor 2 and the Y-axis linear motor 3 near the first belt conveyor line 51, the glue can be smoothly delivered to the dispensing valve 71 and dispensed and encapsulated onto the positioned PCB board according to a preset trajectory and position. The dispensing angle adjustment assembly 73 adjusts the dispensing angle of the dispensing valve 71.

[0029] In the specific implementation process, it is worth noting that the dispensing valve 71 and the glue supply tube 72 together constitute the glue delivery and dispensing system. The glue supply tube 72 continuously delivers glue to the dispensing valve 71. After moving to the designated position, the control system automatically controls the dispensing valve 71 to precisely control the glue flow rate and dispensing time, so as to ensure accurate dispensing operation at the designated position on the PCB board. The dispensing angle adjustment component 73 is used to enable the dispensing valve 71 to flexibly adjust the dispensing angle according to different dispensing requirements and the specific structure of the PCB board. The specific model of the dispensing valve 71 is not limited, as long as it meets the usage requirements. Furthermore, the dispensing angle adjustment component 73 includes a second Z-axis KK module 731, a rotary cylinder 732, and a DD motor 733.

Through the cooperation of the second Z-axis KK module 731, the rotary cylinder 732, and the DD motor 733, the dispensing valve 71 can move and adjust its angle in the Z-axis direction to adapt to the dispensing requirements and dispensing positions of different PCB boards.

[0030] In the specific implementation process, it is worth noting that through the cooperation between the X-axis linear motor 2, Y-axis linear motor 3, dispensing valve 71, glue supply tube 72, second Z-axis KK module 731, rotary cylinder 732, and DD motor 733, the control system accurately calculates the dispensing position and angle based on visual recognition information, and automatically controls the X-axis linear motor 2, Y-axis linear motor 3, and second Z-axis KK module 731 to move the dispensing valve 71 to the appropriate position and height. At the same time, the rotary cylinder 732 and DD motor 733 are used to precisely adjust the angle of the dispensing valve 71, ensuring that the dispensing valve 71 can perform dispensing operation on the PCB board at the optimal angle, improving the dispensing and encapsulation quality of the PCB board, and meeting the diverse dispensing and encapsulation needs of PCB boards of different specifications. The specific models of the second Z-axis KK module 731, rotary cylinder 732, and DD motor 733 are not limited, as long as they meet the usage requirements. Furthermore, the output end of the X-axis linear motor 2 is fixedly connected to a horizontal plate 31, the Y-axis linear motor 3 is fixedly connected to the bottom of the outer wall of the horizontal plate 31, the outer wall of the horizontal plate 31 is fixedly connected to a second slide rail 32 above the Y-axis linear motor 3, and the back of the first Z-axis KK module 661 and the second Z-axis KK module 731 are respectively fixedly connected to a second slide block 33, and the second slide block 33 is slidably connected to the second slide rail 32.

[0031] The working principle of this application is illustrated below with a preferred embodiment: First, the PCB board size specifications are transmitted to the control system. Based on this information, the control system automatically controls the second servo motor 545 to drive the threaded screw 544 to rotate, which in turn drives the second belt conveyor 52 to slide on the first slide rail 541. This adjusts the distance between the first belt conveyor 51 and the second belt conveyor 52 to fit the width of the PCB board to be conveyed. At the same time, the laser range sensor 546 senses the distance between the two belt conveyors in real time and feeds the information back to the control system to ensure the accuracy of the distance adjustment. After the spacing is adjusted, the PCB board enters the conveying surface of the first belt conveyor line 51 and the second belt conveyor line 52 through the front gripping device or conveyor line. The two sides of the PCB board enter the conveying surface between the belt and the frame of the first belt conveyor line 51 and the second belt conveyor line 52 respectively. Through the synchronous rotation of the belt, the PCB board is conveyed from the loading end into the equipment. When the PCB board is transported to the location of the photoelectric sensor 61, the photoelectric sensor 61 senses the PCB board and transmits the signal to the control system. After receiving the signal, the control system immediately stops the first servo motor 53, causing the belt conveyor to stop rotating. At the same time, the first servo cylinder 62 is activated, causing the limit baffle 63 to extend and block the PCB board from continuing to be transported forward. Subsequently, the control system controls the second servo cylinder 64 to move the pressure rod 65 downward, pressing and fixing the PCB board on the conveyor line to prevent it from shifting in subsequent operations. Subsequently, the control system automatically controls the movers of the X-axis linear motor 2 and Y-axis linear motor 3 on the side away from the first belt conveyor 51 and the first Z-axis KK module 661, so that the camera 662, camera 663 and coaxial light source 664 move to a suitable position above the PCB board to acquire images of the PCB board and transmit the acquired image data to the control system. After receiving the image data, the control system analyzes and processes the image through image processing algorithms to accurately calculate the coordinate information of each key position on the PCB board, such as solder joints, pins, chip mounting positions, etc. Based on this coordinate information, the control system accurately calculates the position and angle of the glue dispensing and resets after completing the visual recognition scan. The control system automatically controls the movers of the X-axis linear motor 2 and the Y-axis linear motor 3 near the first belt conveyor 51, as well as the second Z-axis KK module 731, to move the dispensing valve 71 to the appropriate position and height. Simultaneously, the rotary cylinder 732 and the DD motor 733 precisely adjust the angle of the dispensing valve 71, ensuring a continuous supply of glue from the glue supply tube 72. After the dispensing valve 71 reaches the designated position, the control system automatically controls it, precisely controlling the glue flow rate and dispensing time. To ensure that the dispensing valve 71 performs dispensing operations on the PCB board at the optimal angle; After the dispensing and encapsulation operation is completed, the control system automatically controls the first servo cylinder 62, the second servo cylinder 64, and the first servo motor 53 to release the PCB board from its fixation and continue to convey the PCB board forward to the unloading end, completing the entire adaptive positioning and encapsulation integrated operation process for multi-specification PCB boards. After that, the equipment can continue to receive new PCB boards and repeat a series of operations such as conveying, positioning, visual recognition, dispensing and encapsulation, and unloading to continuously produce PCB boards.
