[0026] The interior of the first mounting block 2 and the second mounting block 4 is respectively provided with a heating rod 10 and a thermocouple 11. The rubber material is heated by the heating rod 10 to maintain its fluidity and stability. The temperature of the rubber material is increased by heating to prevent it from solidifying or becoming less fluid due to excessively low temperature. The temperature of the rubber material is monitored by the thermocouple 11 to ensure the heating effect and provide real-time feedback of the temperature information of the rubber material. The heating power of the heating rod 10 is adjusted by the control system to keep the rubber material within a set temperature range. The temperature can be controlled according to the actual use temperature requirement through the heating rod 10 and the thermocouple 11. The surface of the support framework 1 is provided with a visual guidance assembly 7, which includes a first fixing block 701, a camera 702, a lens 703 and a second fixing block 704.

The difference is fed back to the control system to make the Z-axis of the dispensing three-axis make corresponding compensation to maintain the consistency of the dispensing glue line. Then, the control system heats the rubber material in the glue bucket through the heating rod 10 according to the temperature requirement. The temperature of the rubber material is monitored in real time by the thermocouple 11 to ensure that the rubber material is kept within a set temperature range to prevent it from solidifying or becoming less fluid. Then, the control system controls the dispensing valve 5 to open. The air pipe joint 13 arranged on the upper cover can be connected to compressed air to assist in pushing the piston of the glue bucket to discharge glue. The glue is delivered to the dispensing valve 5 through the connecting hose 12. The dispensing valve 5 controls the flow and speed of the glue to realize accurate dispensing. Finally, the dispensing head 6 accurately applies the glue to the target position under the transmission of the dispensing three-axis.

[0030] In summary:

[0031] 1. The design of the T-shaped support framework 1 not only makes full use of the characteristics of the two surfaces of the middle vertical plate that can be fixed and installed to complete the installation of the dispensing valve 5, the visual guiding assembly 7, the laser range finder 9, the glue barrel and other hardware in a very small space, but also ensures that the limited space has enough rigidity to maintain the stability of the overall structure. The glue is extracted from the glue barrel and can be uniformly and accurately dispensed on the workpiece through the dispensing valve 5 cooperating with the three-axis movement. The design of the three-axis dispensing mechanism meets the requirements of high precision and high speed of dispensing, ensuring the efficiency and accuracy of dispensing operation. At the same time, the visual guiding assembly 7 is equipped to identify the opposite corners of the bipolar plate through photography, accurately determine the positioning starting point of the dispensing trajectory, and further improve the precision of dispensing. In addition, the laser range finder 9 selects multiple detection points on the dispensing trajectory, calculates the difference between the actual height and the theoretical height of the dispensing head 6 and the workpiece dispensing surface through internal calculation, and transmits this feedback signal to the Z-axis of the three-axis movement mechanism for real-time compensation, thereby ensuring the consistency of the dispensing line in height.

These temperature control components can be flexibly adjusted according to the actual use temperature, ensuring the smooth operation of dispensing and effectively improving the stability and reliability of the whole. The reasonable integrated design reduces the cost and improves the dispensing precision and efficiency.
