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] Please see Figures 1-9 The present invention provides a linkage-adjustable airtightness-enhancing dispensing system for plastic-coated parts, including a plastic-coated part end tooling assembly 1, an annular electric track assembly 2 is provided outside the plastic-coated part end tooling assembly 1, and an adjustable rectangular track 3 is provided in the middle of the annular electric track assembly 2. The adjustable rectangular track 3 includes four movable corner guide groove assemblies 4, and an expansion straight guide groove 5 is arranged between adjacent two movable corner guide groove assemblies 4, and the four movable corner guide groove assemblies 4 are connected between adjacent two movable corner guide groove assemblies 4 through the expansion straight guide groove 5 during the opening process, forming a square of the adjustable size rectangular track; The radial displacement assembly 6 is arranged on the annular electric track assembly 2 and can move in the radial direction of the annular electric track assembly 2; The vertical holding assembly 7 is arranged between the radial displacement assembly 6 and the adjustable rectangular track 3 and can drive the radial displacement assembly 6 to move along the path of the adjustable rectangular track 3 and always be perpendicular to the adjustable rectangular track 3; The front and rear moving point glue device 8 is arranged on the radial displacement assembly 6; The material holding and conveying assembly 9 is arranged on the annular electric track assembly 2 and is used for holding and conveying point glue material to the front and rear moving point glue device 8 in any direction within the range; The visual detection system 10 is arranged in the middle of the annular electric track assembly 2 and is used for detecting the size of the plastic-coated part. The rectangular plastic-coated part includes a copper bar assembly, a battery module, a magnetic ring and assembly, or an integrated filter assembly, etc. The plastic-coated part such as a copper bar assembly, a battery module, a magnetic ring and assembly, or an integrated filter assembly is fixed through the plastic-coated part end tooling assembly 1, ensuring the position stability during the point glue process. The arc-shaped electric sliding block 203 of the annular electric track assembly 2 can move along the annular electric track 202, providing a circular motion basis for the subsequent point glue related assemblies; The adjustable rectangular track 3 in the middle of the annular electric track 202 is connected with the annular electric track 202 through the rectangular bottom plate 301 and the connecting frame 302. The four movable corner guide groove assemblies 4 are uniformly distributed around the center circle of the rectangular bottom plate 301 and move towards the four corners. The expansion straight guide groove 5 between adjacent movable corner guide groove assemblies 4 expands and contracts with the expansion and contraction of the movable corner guide groove assembly 4, so that the multiple L-shaped grooves 4032 and straight grooves 503 form an adjustable rectangular guide groove 100 matched with the rectangular contour of the plastic-coated part; In the radial displacement assembly 6 on the annular electric track assembly 2, the radial extension rod 601 covers the adjustment range of the adjustable rectangular track 3, and the radial sliding block 603 can move along the radial straight groove 602, realizing the radial approach or away of the point glue device from the plastic-coated part; The two drive wheels 701 of the vertical holding assembly 7 are fixed to the radial sliding block 603 and embedded in the adjustable rectangular guide groove 100. When driving the radial displacement assembly 6 to move along the path of the adjustable rectangular guide groove 100, the vertical holding assembly 7 always keeps perpendicular to the adjustable rectangular guide groove 100, ensuring the accuracy of the point glue angle; The front and back moving point glue device 8 on the radial slider 603 can move along the axial electric track 801, realizing the point glue to the different axial positions of the plastic coated part; The material holding and conveying assembly 9 on the annular electric track assembly 2 moves along the axial guide rod structure 901 through the movable conveying ring 902.

[0020] After the vision detection system 10 detects the size of the rectangular plastic coated part, the four movable corner guide groove assemblies 4 of the adjustable rectangular track 3 move along the inclined guide groove 401 through the inclined slider 402, driving the L-shaped part 4031 and the L-shaped groove 4032 to open or shrink towards the four corners. At the same time, the expansion straight groove 5 between the adjacent L-shaped grooves 4032 expands or shrinks along the internal guide groove 501 through the expansion straight rod 502, so that the L-shaped groove 4032 and the straight groove 503 form a completely matched adjustable rectangular guide groove 100 with the size of the plastic coated part, providing an adaptive rectangular motion path for the front and back moving point glue device 8.

[0022] The axial position adjustment and continuous dispensing In the moving process along the rectangular path, the movable dispensing device 802 of the front and rear moving dispensing device 8 can move forward and backward along the axial electric track 801, and the dispensing distance is accurately adjusted for the gaps at different axial positions of the outer periphery of the rectangular plastic part, such as the multi-layer splicing joints of the copper bar assembly and the side step joints of the battery module; at the same time, the material holding and conveying assembly 9 continuously conveys glue to the movable dispensing device 802 through the extension and retraction of the radial extension conveying pipe 906 and the rotation of the angle adjusting ring 9050, and finally realizes continuous and uniform dispensing around the outer periphery of the product.
