[0003] Traditional cardboard box dispensing machines have several shortcomings. First, they require manual measurement of cardboard box dimensions and manual parameter input, which is inefficient, error-prone, and consumes significant manpower and time. Second, fixed positioning devices are difficult to adapt to cardboard boxes of different sizes, requiring equipment readjustment when changing products, greatly limiting production flexibility and efficiency, and reducing equipment utilization. Third, cardboard box materials are prone to warping and deformation, and traditional equipment lacks height adaptability. When cardboard box heights are inconsistent, dispensing defects are easily caused, affecting dispensing accuracy and quality, leading to an increased defect rate. Fourth, the fixed dispensing path cannot be automatically optimized according to the actual cardboard box size, resulting in problems such as movement pauses and sharp turns, further reducing dispensing efficiency and quality. To address the shortcomings of existing technologies, this invention provides an intelligent adaptive cardboard box dispensing mechanism and its control method to solve the above problems.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods. Example

[0024] This invention discloses an intelligent adaptive cardboard box dispensing mechanism, according to the attached... Figure 1 To be continued Figure 4 As shown, it includes a frame 1, a dispensing carrier module 2, a dispensing execution module 3, and an intelligent control module; Frame 1 is the load-bearing structure of the entire intelligent adaptive carton dispensing mechanism, ensuring the stability and reliability of the mechanism during operation.

[0025] The dispensing carrier module 2 is mounted on the frame 1. The dispensing carrier module 2 includes a carton fixing module 201, an X-direction positioning block 202, a Y-direction positioning block 203, and a position sensor. The carton fixing module 201 is equipped with vacuum suction holes. When a carton is placed on the module, the vacuum suction holes are activated, and the carton is suctioned by negative pressure, greatly improving the fixing effect of the carton and preventing displacement of the carton during the dispensing process.

[0026] The X-direction positioning block 202 and the Y-direction positioning block 203 are driven by servo motors fixedly connected to the carton fixing module 201. Driven by the servo motors, the positioning blocks in the X and Y directions can move precisely to clamp and fix the carton. Simultaneously, position sensors can acquire the length and width dimensions of the carton in real time and transmit the data to the intelligent control module. This design allows the dispensing carrier module 2 to adapt to cartons of different sizes without manual adjustment, greatly improving production efficiency and flexibility, and reducing changeover time by 80%.

[0027] The dispensing execution module 3 is mounted on the frame 1 and includes a glue gun, a height measuring module 305, and a dispensing module 304. The glue gun is the core component for performing the dispensing operation; it accurately applies glue to designated locations on the carton according to instructions from the intelligent control module. The height measuring module 305 uses a non-contact laser rangefinder with a measurement accuracy of ±0.1mm. Before dispensing, the height measuring module 305 performs multi-point measurements on the carton surface to obtain height distribution data and transmits the data to the intelligent control module.

[0028] The dispensing execution module 3 is equipped with an X-axis transfer unit 301, a Y-axis transfer unit 302, and a Z-axis transfer unit 303 for motion control of the dispensing module 304. The dispensing module 304 adopts linear guide rails and ball screw drives, which features high precision, high stability, and low friction, ensuring precise movement of the glue gun in the X, Y, and Z directions, achieving high-precision dispensing operations. By acquiring the carton height data through the height measuring module 305 and combining it with the precise movement of the dispensing module 304, this module can effectively prevent dispensing defects caused by carton warping or inconsistent height, improving dispensing accuracy and consistency, and reducing the defect rate.

[0029] The intelligent control module, mounted on frame 1, includes a PLC controller, a motion controller, and a human-machine interface (HMI). The PLC controller handles the logic control and data processing of the entire mechanism. It receives sensor data from the dispensing carrier module 2 and the dispensing execution module 3, and processes it according to preset programs and algorithms. The motion controller, following instructions from the PLC controller, controls the movement of the dispensing module 304, ensuring the glue gun dispenses glue along a planned path. The HMI provides an interactive platform between the operator and the mechanism, allowing the operator to set dispensing parameters, monitor the dispensing process, and view production data. The intelligent control module incorporates an adaptive algorithm that automatically generates the optimal dispensing path based on measurement data. This algorithm automatically optimizes the dispensing path according to the actual carton size and shape, reducing pauses and sharp turns, and improving dispensing efficiency and quality. Furthermore, this module lowers the technical requirements for operators; operators do not need specialized programming or debugging skills to easily operate the mechanism. Example
