Detailed Implementation

[0025] In this embodiment, refer to Figures 1-9 The filter element capping assembly machine includes a body 1 and a control system. A feeding mechanism, a discharging mechanism 7 (discharging robot), and an assembly mechanism are set on the worktable of the body 1. The feeding mechanism and the assembly mechanism are controlled by the control system. The feeding mechanism includes a paper core feeding mechanism, a top cover feeding mechanism, and a bottom cover feeding mechanism. A first circulation mechanism 2 and a second circulation mechanism 21 are installed on the worktable of the body 1. Both the first circulation mechanism 2 and the second circulation mechanism 21 are equipped with fixtures 23. The fixtures are equipped with multiple material feeding slots 24, such as four, so that four filter elements can be assembled at one time. The assembly mechanism includes a top cover transfer mechanism 3, a bottom cover transfer mechanism 5, a material transfer mechanism 6, and a pressing mechanism 7. The top cover transfer mechanism 3 is connected to the top cover feeding mechanism, and the bottom cover transfer mechanism 5 is connected to the bottom cover feeding mechanism. The top cover transfer mechanism 3 and the material transfer mechanism 6 are located next to the first circulation mechanism 2. Paper core A can be placed into the feeding trough 24 of the fixture 23 of the first circulation mechanism 2 by manual or robotic arm. The upper cover B is placed on paper core A by the upper cover transfer mechanism 3. The lower cover C is placed in the feeding trough 24 of the second circulation mechanism 21 by the lower cover transfer mechanism 5. The paper core A and upper cover B assembly is transferred to the lower cover C located in the feeding trough 24 of the second circulation mechanism 21 by the transfer mechanism 6. The paper core A and upper cover B assembly is pressed by the pressing mechanism 7 to achieve assembly with the lower cover C.

[0026] The first circulation mechanism 2 includes a circulation platform 22 and a plurality of fixtures 23, each fixture 23 having four feeding slots 24; a conveying slot is provided on the circulation platform 22 for realizing the cyclic movement of the fixtures 23, and each fixture 23 is placed on the circulation platform 22 along the conveying slot; a longitudinal push cylinder 25 and a transverse push cylinder 27 are respectively provided on the circulation platform 22 near both ends, the longitudinal push cylinder 25 is connected to a longitudinal push rod 26, the longitudinal push rod 26 is engaged with the outer end of the fixture 23 located at the first end, and the longitudinal push cylinder 25 drives the longitudinal push rod 26 to push. The fixture 23 moves longitudinally within the conveying trough; the transverse push cylinder 27 is connected to the transverse push rod 28, which is engaged with the outer side of the fixture 23 at the end. The transverse push cylinder 27 drives the transverse push rod 28 to push the fixture 23 laterally from one side of the conveying trough to the other side on the circulation platform 22, thus forming a closed-loop production line; the second circulation mechanism 21 has the same structure as the first circulation mechanism 2, the only difference being that the total length may be shorter, and the fixture placement slot will be slightly different according to the shape of the bottom cover.

[0027] The top cover transfer mechanism 3 includes two opposing material support plates 31. Grooves are provided along the sides of the material support plates 31. The spacing between the grooves is the same as the spacing between the material discharge grooves 24, and there can also be four grooves. The grooves of the two material support plates 31 are arranged opposite each other, and the two material support plates 31 are respectively connected to telescopic cylinders 33 to form an openable structure. Telescopic clamping claws 32 are provided on the material support plates 31 near the grooves. When the material support plates 31 are closed, the clamping claws 32 clamp the top cover B. When the two material support plates 31 are opened, the top cover B will automatically fall onto the paper core A through the grooves. The telescopic cylinders 33 of the two material support plates 31 are respectively mounted in a mounting bracket 34 at both ends through bearings. A flipping motor 39 is provided on the mounting bracket 34. The flipping motor 39 is connected to the telescopic cylinders 33 through a belt and pulley 310 to form a flipping structure for the top cover B. This is because, for the convenience of feeding the top cover B, the top cover B adopts an inverted feeding method. When it is transferred to the paper core A, it needs to be rotated 180 degrees to return the top cover B to the upright position. This process is achieved by the flipping motor 39 driving the telescopic cylinder 33 and the material support plate 31 to rotate 180 degrees together. A support frame 35 is set on the mounting bracket 34, a lifting mechanism 37 is installed on the support frame 35, a top cover transfer bracket 36 is installed on the lifting mechanism 37, and a horizontal movement motor 38 is installed on the top cover transfer bracket 36. The entire top cover transfer mechanism 3 is suspended above the top cover feeding mechanism by a fixed plate 30 on the protective cover (not shown) above the machine body, so as to realize the lifting and horizontal movement of the top cover B.

[0028] A spacing adjustment mechanism 41 is provided below the cover feeding mechanism. Four pneumatic grippers 42 are mounted on the spacing adjustment mechanism 41, each corresponding to one cover B. The entire spacing adjustment mechanism 41 is mounted on a support plate 43, which is connected to a lifting motor 44. The lifting motor 44 drives the spacing adjustment mechanism 41 to rise, allowing the pneumatic grippers 42 to insert into the cover B and lift it. Once the pneumatic grippers 42 are inserted into the holes of the cover B, they open, thus gripping the cover B. Since the covers B are usually conveyed one after another, but the feed troughs 24 of the fixture 23 have a certain spacing, the spacing adjustment mechanism 41 is used to drive the pneumatic grippers 42 to adjust the spacing of the covers B to match the spacing of the feed troughs 24.

[0029] The bottom cover transfer mechanism 5 includes grippers 55 and a spacing adjustment module 54. Four grippers 55 are connected to the spacing adjustment module 54, each gripper 55 corresponding to a bottom cover C. The grippers 55 hold the bottom cover C, and when it moves above the fixture 23 corresponding to the second circulation mechanism 2, the grippers 55 release the bottom cover C, and the bottom cover C falls into the material discharge trough of the fixture. The spacing adjustment module 54 is mounted on a lifting bracket 53, which is connected to a lifting module 52. The lifting module 52 is mounted on a bottom cover transfer bracket 51, which is suspended above the bottom cover transfer mechanism by a mounting plate 50 suspended on a protective cover above the machine body. The spacing adjustment module 54 of the bottom cover transfer mechanism 5 has a structure basically the same as the aforementioned spacing adjustment mechanism 41, and can directly utilize existing product spacing adjustment devices. Its function is also the same; it is used to adjust the spacing of the bottom covers C. The movement process of the bottom cover transfer mechanism 5 is similar to that of the top cover transfer mechanism 3, and will not be described in detail here.

[0030] The material transfer mechanism 6 is mounted on the mounting plate 50 and suspended above the first circulation mechanism 2 and the second circulation mechanism 21. The structure of the material transfer mechanism 6 is roughly the same as that of the upper cover transfer mechanism 3, the main difference being the absence of the clamping claw 32 and the flipping structure. After its support plate closes, the material transfer mechanism 6 clamps the paper core A, and then moves it together with the upper cover B above it to the adjacent second circulation mechanism 21. After aligning it with the already moved bottom cover C, the assembly of paper core A and upper cover B is released, and paper core A is pressed onto the bottom cover C.

[0031] Above the two conveying grooves on the first circulation mechanism 2, pressing mechanisms 9 are respectively provided for flattening the paper core A and pressing the upper cover B to the paper core A (the upper cover B is coated with glue to bond it to the paper core A). The pressing mechanism 9 includes a pressing plate 93 and a pressing cylinder 92. The pressing plate 93 is connected to the pressing cylinder 92, which is mounted on a pressing bracket 91 that spans above the fixture 23. The pressing cylinder 92 drives the pressing plate 93 downwards to press the paper core A and the upper cover B.

[0032] The paper core feeding mechanism uses a paper core conveyor belt 11. Paper core A can be placed on the paper core conveyor belt 11 manually or by a robot, and then transported to the operating station by the paper core conveyor belt 11. Then, paper core A is placed in the placement slot 24 of the fixture 23 of the first circulation mechanism 2 manually or by a robot. The top cover feeding mechanism uses a top cover conveyor belt 12. Top cover B is placed on the top cover conveyor belt 12 manually or by a robot. The bottom cover feeding mechanism uses a bottom cover conveyor belt 13. Bottom cover C is placed on the bottom cover conveyor belt 13 manually or by a robot. The spacing adjustment mechanism 41 is set below the top cover conveyor belt 12. Stopping cylinders 14 are respectively set on the top cover conveyor belt 12 and the bottom cover conveyor belt 13 to intercept the top cover B and the bottom cover C, respectively, to ensure that four top covers B and four bottom covers C enter the operating station in each group.

[0033] A sensing device 10, such as an infrared sensing device, is installed next to the first circulation mechanism 2, next to the upper cover conveyor belt 12, and next to the bottom cover conveyor belt 13. These devices are used to detect whether the paper core A, upper cover B, and bottom cover C are in place. Only after the detection is complete can the next operation be started.

[0034] The feeding mechanism 7 is located near the end of the second circulation mechanism 21 and is used to remove the assembled paper core, top cover and bottom cover assembly from the second circulation mechanism 2 to complete the feeding.

[0035] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
