[0031] Please refer to Figures 1 to 11 As shown in the figure, the utility model discloses a kind of pipe visual assembly equipment, including rack, conveying mechanism 1 for being set on rack for conveying and carrying outer tube, first feeding mechanism 2 for supplying bottom cover, first loading mechanism 3 for loading bottom cover supplied by first feeding mechanism 2 into outer tube, first visual mechanism 4 for assisting outer tube and bottom cover assembly by cooperation shooting, first pressing mechanism 5 for being inserted into outer tube and being in contact with bottom cover so that bottom cover is pressed and held in the lower end of outer tube, second feeding mechanism 6 for supplying inner tube, second loading mechanism 7 for loading inner tube supplied by second feeding mechanism 6 into outer tube equipped with bottom cover, second visual mechanism 8 for assisting outer tube and inner tube assembly by cooperation shooting, second pressing mechanism 9 for being in contact with and pressing inner tube protruding out of the upper end of outer tube.

[0033] Specifically, the visual mechanism has a camera 13 arranged on the rack, and a ring-shaped light source 14 arranged around the camera 13, which provides illumination conditions for the camera 13 to shoot the measured object; the rack is provided with two light sensors 15 used in cooperation with the conveying mechanism 1, the two light sensors 15 correspond to the two visual mechanisms, when the outer tube blocks the light sensor 15, the light sensor 15 triggers the conveying mechanism 1 to stop moving to make the visual mechanism take pictures and the loading mechanism work.

[0034] In actual use, the double light sensors 15 and the conveying mechanism 1 form a closed loop control, when the outer tube blocks the light sensor 15 of the corresponding station, the system completes the braking of the conveying mechanism 1 in a short time, ensures that the visual mechanism completes the positioning of the camera in a static environment, avoids the influence of motion blur on the detection accuracy, and realizes the millimeter-level dynamic compensation of the loading mechanism.

[0035] Specifically, the rack is provided with a rotating mechanism 21 for cooperating with the outer tube conveyed by the conveying mechanism 1, the rotating mechanism 21 is used to drive the rotation of the circular tube, the rotating mechanism 21 has a rotating assembly 22, the rotating assembly 22 has a driving wheel set 23 and a driven wheel set 24 located on both sides of the circular tube respectively, a first driving member 25 driving the driving wheel set 23 to rotate, the driving wheel set 23 and the driven wheel set 24 are used to abut on both sides of the circular tube, and the first driving member 25 drives the driving wheel set 23 to rotate to change the pose of the outer tube.

[0036] In actual use, a double-wheel set clamping type rotating structure is adopted, the first driving member 25 realizes the rotation of the outer tube through closed-loop servo control, cooperates with the real-time angle detection of the visual mechanism, dynamically adjusts the position of the outer tube during assembly, ensures the accurate alignment of the positioning pin holes of the bottom cover and the inner tube, and significantly improves the assembly success rate of complex structural parts.

The first carrier plate 27 and the second carrier plate 28 are slidingly arranged on the first sliding rail 26, so that the installation positions of the driving wheel set 23 and the driven wheel set 24 can be adjusted conveniently. During installation of the equipment, the positions of the wheel sets can be accurately positioned according to actual requirements; during daily maintenance, if the wheel sets are damaged, they can be easily slid out along the sliding rail for quick repair or replacement, which greatly shortens the equipment downtime and improves the maintainability of the equipment.

Whether high-speed rotation or precise fine adjustment, the stable posture can be maintained, which greatly improves the stability of the circular pipe during rotation and ensures the accuracy of the subsequent assembly process. The four rollers are in large-area contact with the circular pipe, and compared with a single roller, the friction force is more uniformly distributed, which can more efficiently transmit the power of the driving wheel set 23 to the circular pipe to realize fast and stable rotation. When driving the circular pipe to rotate, the power transmission loss is smaller, so that the overall transmission efficiency of the rotating mechanism 21 is significantly improved, which can effectively shorten the production cycle and improve the production efficiency.

[0042] In actual use, through the precise design of the height of the feeding gap, the reciprocating pressing of the pressing member 44 and the stopping of the baffle 43, it is ensured that the bottom covers pass through one by one in a single row under the action of gravity, the problems of stacking and jamming or simultaneous conveying of multiple pieces are effectively avoided, the stability of the feeding and the safety of the equipment operation are improved. After the first mechanical arm 47 drives the suction cup 46 to adsorb the bottom cover, the inclined position of the bottom cover can be flexibly adjusted, so that the bottom cover is accurately embedded into the outer pipe at the best angle, the collision or jam caused by vertical assembly is avoided, the assembly efficiency and the product qualification rate are significantly improved, and the demand for manual intervention is reduced.

[0043] Specifically, the second feeding mechanism 6 has a second conveying belt 51 rotatably arranged on a rack, a fourth driving member 52 for driving the second conveying belt 51 to rotate for conveying the inner pipe, and a second feeding position 53 arranged on the second conveying belt 51 and used for supplying the second feeding mechanism 7 with the inner pipe; the second feeding mechanism 7 has a clamping jaw 54 arranged on the rack, a second mechanical arm 55 for driving the clamping jaw 54 to move, a fifth driving member for driving the clamping jaw 54 to clamp the inner pipe, and a rotary driving source for driving the inner pipe clamped by the clamping jaw 54 to rotate, the fourth driving member 52 drives the second conveying belt 51 to convey to the second feeding position 53, the fifth driving member drives the clamping jaw 54 to clamp the inner pipe on the second feeding position 53, after the second mechanical arm 55 drives the clamping jaw 54 to move above the outer pipe, the rotary driving source drives the inner pipe clamped by the clamping jaw and rotates to extrude the inner pipe into the outer pipe.

[0044] In actual use, the second feeding mechanism 6 is stably driven by the fourth driving member 52 to quickly and accurately convey the inner tube to the second feeding position 53, thereby providing efficient material supply for the subsequent assembly process.

[0046] In actual use, the first pressing head 61 is designed as a circular plate, which fits the internal space of the outer tube and can maintain a stable posture when entering the outer tube, thereby reducing shaking and deviation and ensuring smooth progress of the pressing process. The second pressing head 63 is also a circular plate, which fully contacts the top end of the inner tube, thereby increasing the force receiving area, effectively dispersing the pressing force during pressing, preventing the inner tube from deforming due to uneven local stress, and making the pressing operation more stable and reliable, thereby laying a foundation for high-quality assembly. The circular plate-shaped first pressing head 61 of the first pressing mechanism 5 has an outer diameter that is adapted to the inner diameter of the outer tube, and under the precise control of the third mechanical arm 62, can smoothly enter the outer tube and uniformly abut against the bottom cover, thereby firmly pressing the bottom cover at the lower end of the outer tube, ensuring that the bottom cover is closely fitted with the outer tube, avoiding gaps or looseness, and ensuring the initial assembly quality of the product. The second pressing head 63 of the second pressing mechanism 9 has an outer diameter that is greater than the inner tube, and the fourth mechanical arm 64 drives it to accurately abut against the protruding end of the inner tube, thereby uniformly applying force to seamlessly connect the inner tube and the outer tube at the assembly position, thereby improving the overall assembly tightness.

[0048] In actual use, the first glue nozzle 71 of the first glue applying mechanism 11 can accurately extend into the bottom of the outer tube under the precise control of the fifth mechanical arm 72, and evenly apply glue to the inner edge of the bottom of the outer tube. The rotation mechanism 21 drives the rotation of the circular tube, which cooperates with the first glue nozzle 71 to ensure that the glue is covered 360°, effectively enhancing the sealing and firmness of the connection between the bottom cover and the outer tube, preventing problems such as water leakage and loosening caused by uneven glue application, and greatly improving product quality and durability. The fifth mechanical arm 72 quickly drives the positioning of the first glue nozzle 71, and the rotation mechanism 21 quickly drives the rotation of the circular tube, both of which work together to greatly shorten the glue application time of a single circular tube. In the automatic production line, it closely connects with the previous and subsequent processes, significantly improves the overall production rhythm, meets the demand of large-scale production, helps enterprises to improve production capacity, and occupies an advantage in market competition.

[0049] Specifically, the second glue applying mechanism 12 has a second glue nozzle 73, a sixth mechanical arm 74 for driving the movement of the second glue nozzle 73, a glue supply unit connected to the outside world through the second glue nozzle 73, and the sixth mechanical arm 74 drives the glue sprayed by the second glue nozzle 73 to be applied to the inner side wall of the bottom of the outer tube.

The combination of the second glue nozzle 73 and the sixth mechanical arm 74 can flexibly cope with outer tubes of different diameters, lengths and shapes. Whether it is a regular straight outer tube or a special-shaped tube with special curvature, it can accurately position the glue application area. The flexible speed adjustment function of the rotation mechanism 21 can adjust the rotation speed of the circular tube according to the diameter difference, ensure the uniformity of the glue thickness, make the equipment adapt to multiple product specifications, and reduce the equipment procurement and maintenance costs of enterprises.
