The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application.

[0022] As Figure 1 shown in the drawings, one embodiment of the utility model is:

[0023] The automatic glue amount compensation system according to seam width comprises a PC industrial computer 1, an electronic scale 2, a 3D line laser 3, a motion control board card 4, a driver 5 and a shaft system motor 6.

[0024] The PC industrial computer 1 is in communication connection with the electronic scale 2, the 3D line laser 3 and the motion control board card 4.

[0025] The electronic scale 2 is in communication connection with the PC industrial computer 1, and is used for weighing the total glue amount required for dispensing by simulation weighing.

[0026] The 3D line laser 3 is in communication connection with the PC industrial computer 1, and is used for scanning the three-dimensional profile information of a dispensing product to obtain seam width data of a dispensing track.

[0027] The motion control board card 4 is in communication connection with the PC industrial computer 1 and the driver 5 respectively, and is used for receiving the motion control instructions, parameters and data of the PC industrial computer 1, generating corresponding motion control signals and sending the signals to the driver 5.

[0028] The driver 5 is in communication connection with the shaft system motor 6, and is used for receiving the control signals output by the motion control board card 4 to drive the shaft system motor 6 to move.

[0029] In the embodiment, the PC industrial computer 1 undertakes the work of signal processing, data operation, instruction issuing and communication coordination with other components. It has strong computing capacity and stable running performance, can quickly process a large amount of data from the electronic scale 2 and the 3D line laser 3, and generate accurate motion control instructions according to a preset algorithm and send the instructions to the motion control board card 4.

[0030] The electronic scale 2 simulates the actual dispensing process by using simulation weighing technology according to the set dispensing track of a product and the reference speed, and accurately weighs the total glue amount required for completing the entire dispensing task. This data provides a basis for subsequent glue amount allocation and control.

[0031] The 3D line laser 3 transmits the collected seam width data of the dispensing track to the industrial computer in real time through communication connection with the PC industrial computer 1. The 3D line laser in the embodiment is of LJ-X8000 type.

[0032] The motion control board card 4 receives the motion control instructions, various parameters and data from the industrial computer, including the actual dispensing speed of each trajectory calculated according to the seam width; on the other hand, according to these information, the built-in professional control algorithm is used to generate corresponding pulse signals or analog voltage signals and other motion control signals, and accurately send them to the driver 5 to accurately control the movement of the shaft motor 6.

[0033] The driver 5 is responsible for receiving the control signals output by the motion control board card 4, thereby driving the shaft motor 6 to move according to the predetermined requirements.

[0034] The shaft receives the power instructions from the driver 5 and drives the dispensing equipment to move accurately.

[0035] When working, the PC industrial computer 1 sends the simulation weighing instructions to the electronic scale 2 according to the preset dispensing trajectory and reference speed information, and the electronic scale 2 simulates the process of the glue gun moving along the dispensing trajectory at the reference speed according to the received instructions and information, and uses its high-precision sensor to monitor the "glue amount" change in real time. After simulating dispensing, the electronic scale 2 transmits the total glue amount data required for dispensing back to the PC industrial computer 1 through the communication link.

[0036] The PC industrial computer 1 sends scanning instructions to the 3D line laser 3 to perform three-dimensional contour scanning on the product area to be dispensed, and extracts the seam width data of each point on the dispensing trajectory. These seam width data are transmitted back to the PC industrial computer in digital signal form in real time.

[0037] After receiving the total glue amount data from the electronic scale 2 and the seam width data from the 3D line laser 3, the PC industrial computer 1 enters the core data processing link. First, it calculates the reference seam width according to the seam width data of all points according to the preset algorithm (such as arithmetic mean method, weighted average method, etc.). Then, according to the internal relationship model between glue amount, seam width and dispensing speed, combined with the reference speed, the reference seam width and the actual seam width of each point, the dispensing trajectory is segmented, and the actual dispensing speed of each segment is accurately calculated.

[0038] The PC industrial computer 1 sends the calculated actual dispensing speed of each segment and the corresponding motion control parameters (such as target position, acceleration, etc.) to the motion control board card 4.

[0039] After receiving these instructions and data, the motion control board card 4 immediately starts the built-in motion control algorithm, generates corresponding motion control signals according to the motor type (such as stepper motor or servo motor), and sends the generated motion control signals to the driver 5 through the communication interface.

[0040] After receiving the signal, the drive shaft motor 6 moves according to the predetermined trajectory and speed. The shaft motor 6 drives the glue gun to move accurately to the dispensing starting position, and then drives the glue gun to move along the dispensing trajectory at a calculated speed under the continuous driving of the motion control signal. During dispensing, the glue gun dispenses glue according to the actual dispensing speed of each trajectory. For example, when the product dispensing position gap is large and a large amount of glue is needed, the speed at this position will be slow, so the amount of glue will be a little more. Conversely, if the dispensing position gap is narrow and does not require so much glue, the dispensing speed calculated for the narrow gap will be faster, and the amount of glue will be less, thereby achieving automatic compensation of the amount of glue for different gap widths.

[0041] In one embodiment, the shaft motor 6 has multiple shaft motors 6, and each shaft motor 6 is connected to the driver 5 for executing the position instruction of the driver 5 to drive the corresponding shaft motor 6 to rotate.

[0042] It can be understood that the multiple shaft motors 6 at least include X-axis motor, Y-axis motor and Z-axis motor, and the driver 5 can drive multiple drive motors to move simultaneously. The dispensing shafts are controlled in different directions (such as X, Y and Z axes) to receive the movement instructions from the driver 5, drive the glue gun to move accurately, and realize accurate positioning of the glue gun in three-dimensional space to ensure that the glue can be accurately applied to the dispensing area.

[0043] In one embodiment, the PC industrial computer 1 is connected to the electronic scale 2 through a serial port. The serial communication line is relatively simple, and only a few signal lines are needed to achieve basic communication functions. Compared with other complex communication interfaces, the serial port has strong anti-interference ability. In industrial environments, there may be various electromagnetic interferences, and simple serial line layout can effectively reduce the influence of interference on signal transmission, ensuring stable data transmission between the PC industrial computer 1 and the electronic scale 2.

[0044] In one embodiment, the 3D line laser 3 is connected to the PC industrial computer 1 through a Gigabit Ethernet interface, and is used to transmit the collected seam width data to the PC industrial computer 1.

[0045] 3D line laser 3 scanning obtains the point product three-dimensional contour information data volume generally very big. For example, high resolution 3D line laser 3 scanning equipment can produce several million points three-dimensional coordinate data per second. The transmission rate of Gigabit Ethernet interface can reach 1000Mbps (theoretical value), which can quickly transmit these massive data to PC industrial computer 1, greatly shortens the data transmission time, reduces the delay in the data transmission process, ensures that PC industrial computer 1 can obtain the latest scanning data in time, so as to realize real-time analysis of product surface contour and gap width.

[0046] In one embodiment, the motion control board card 4 is connected with the PC industrial computer 1 through the PCIE interface.

[0047] The PCIE interface has very high data transmission rate, which can quickly transmit the data collected by the motion control board card 4 to the PC industrial computer 1 for processing, and also can timely send the control instructions generated by the PC industrial computer 1 to the motion control board card 4, ensuring the real-time and accuracy of motion control, reducing system delay, and realizing more accurate motion control.

[0048] In one embodiment, the motion control board card 4 is connected with the driver 5 through the RJ-45 interface. The RJ-45 interface is mainly used for Ethernet communication and can support various high-speed communication protocols. In the motion control system, these protocols can realize fast data transmission between the motion control board card 4 and the driver 5. Through the RJ-45 interface, nanosecond-level synchronization accuracy and high-speed data exchange can be realized, which can meet the needs of high-precision and high-speed motion control. This high-speed communication performance enables the motion control board card 4 to timely send control instructions to the driver 5, and the driver 5 can quickly feed back the state of the motor to the motion control board card 4, ensuring the real-time and accuracy of motion control.

[0049] In one embodiment, a display screen is further included, which is connected with the PC industrial computer 1. The display screen provides a man-machine interface for the PC industrial computer 1, which is convenient for the operator to set parameters, monitor and debug the system.

[0050] It should be noted that the above technical features continue to be combined to form various embodiments not listed above, which are considered to be within the scope of the description of the present application; and for those skilled in the art, the above description can be improved or changed, and all these improvements and changes should belong to the protection scope of the appended claims of the present application.
