Description

Technical Field

[0001] The utility model belongs to the technical field of lamination production, and particularly relates to a lifting mechanism for lamination feeding. Background Art

[0002] like Figure 1 As shown, the structure commonly adopted by some pole piece loading robots in the prior art is: a servo motor plus a cam divider as the power source of the rotating part, a servo motor plus a cam mechanism as the lifting power source, and a rocker arm and a suction cup assembly at the end as a pole piece grabbing device.

[0003] The disadvantage of this structure is that the rotating component has a large inertia due to its long swing arm. If the cam lifting mechanism is placed on top of the rotating component, the servo motor, reducer, and cam mounting parts of the lifting mechanism will have a large mass, which increases the inertia of the rotating system and becomes a bottleneck affecting the speed of the loading robot. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a lifting mechanism for stack loading, which aims to solve the problem in the existing technology that the cam lifting mechanism is placed above the rotating assembly, the servo motor, reducer, and cam mounting parts of the lifting mechanism are of large mass, which increases the inertia of the rotating system and affects the speed of the loading robot.

[0011] A mounting plate, the mounting plate being mounted on the lifting assembly;

[0012] A rotating assembly is installed on the mounting plate, and a suction cup assembly is installed on the rotating assembly.

[0013] Preferably, the lifting assembly includes a servo motor fixedly mounted on a mounting bracket, and a cam mechanism is fixedly mounted on an output end of the servo motor via a coupling.

[0014] Furthermore, the cam mechanism includes a rotating shaft and a rocker fixed on a side of the rotating shaft away from the servo motor.

[0015] Furthermore, the lifting assembly further comprises a lifting plate used in conjunction with the cam mechanism, and the lifting plate is provided with a slide groove which cooperates with the rocker, and the rocker extends into the interior of the slide groove;

[0016] The top of the lifting plate is fixedly connected to the bottom of the mounting plate.

[0017] Furthermore, the rotating assembly includes a DD motor fixedly connected to the mounting plate and a swing arm fixedly connected to the output shaft of the DD motor.

[0020] Furthermore, a gap is left between the mounting plate and the sliding block.

[0021] (3) Beneficial effects

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0030] This specific embodiment is a stacking material lifting mechanism, and its structural diagram is as follows Figure 2-Figure 5 As shown, the stack loading lifting mechanism includes:

[0031] The base 1 supports the entire stack loading jacking mechanism.

[0032] The mounting bracket 2 is fixedly connected to the base 1 . Specifically, the bottom of the mounting bracket 2 is fixedly connected to the top of the base 1 .

[0033] The lifting assembly 3 is installed on the mounting bracket 2 .

[0034] The mounting plate 4 is mounted on the lifting assembly 3 .

[0035] The rotating assembly 5 is mounted on the mounting plate 4 . A suction cup assembly 6 is mounted on the rotating assembly 5 . The suction cup assembly 6 is used to absorb the pole piece.

[0036] The lifting assembly 3 includes a servo motor 31 fixedly mounted on the mounting bracket 2. A cam mechanism is fixedly mounted on the output end of the servo motor 31 via a coupling. The cam mechanism includes a rotating shaft 33 and a rocker 34 fixed to the side of the rotating shaft 33 away from the servo motor 31. The lifting assembly 3 also includes a lifting plate 32 for use with the cam mechanism. The lifting plate 32 has a slide groove 35 that cooperates with the rocker 34. The rocker 34 extends into the interior of the slide groove 35.

[0037] The servo motor 31 is started to drive the rotating shaft 33 to rotate. The rotating shaft 33 can drive the rocker 34 to rotate during the rotation process. Since the rotating shaft 33 and the rocker 34 form a cam mechanism and the rocker 34 is installed on the middle position side of the rotating shaft 33 away from the servo motor 31, when the rotating shaft 33 drives the rocker 34 to rotate, the rocker 34 slides in the slide groove 35 opened inside the lifting plate 32. Therefore, during the rotation process, the rocker 34 can drive the lifting plate 32 to perform a lifting and reciprocating motion through the cooperation of the slide groove 35.

[0038] The top of the lifting plate 32 is fixedly connected to the bottom of the mounting plate 4. In order to enhance the support strength of the lifting plate 32 on the mounting plate 4, an inverted L-shaped support rod is fixedly connected to both ends of the side of the lifting plate 32 away from the servo motor 31. This increases the contact area between the mounting plate 4 and the lifting plate 32, thereby improving the stability of the mounting plate 4.

[0039] At the same time, the lifting plate 32 can drive the mounting plate 4 to perform lifting and reciprocating motions during the lifting and reciprocating motions, and the mounting plate 4 drives the rotating assembly 5 and the suction cup assembly 6 to perform lifting and reciprocating motions.

[0040] The rotating assembly 5 includes a DD motor 51 fixedly connected to the mounting plate 4 and a swing arm 52 fixedly connected to the output shaft of the DD motor 51. The power source of the rotating assembly 5 is changed from the previous servo motor with a reducer to a direct drive of the DD motor 51, which reduces the size and weight of the assembly and is conducive to high-speed movement. At the same time, the swing arm 52 on the rotating assembly 5 adopts a lightweight design to reduce the rotational inertia.

[0041] The suction cup assembly 6 is fixedly mounted on the end of the swing arm 52 away from the DD motor 51. Each suction cup of the suction cup assembly 6 has a spring compression stroke to adapt to the uneven surface of the conveyor belt when grabbing the pole piece. The structure and principle of the suction cup assembly 6 are the same as those of the suction cup assembly of the jacking mechanism for stacking materials in the prior art, and will not be repeated here.

[0042] Both ends of the side of the lifting plate 32 close to the servo motor 31 are fixedly connected to the sliding block 7, the sliding block 7 is slidably connected to the slide rail 8, and the slide rail 8 is fixedly connected to the mounting bracket 2;

[0043] During the movement, the lifting plate 32 can drive the sliding block 7 to move on the slide rail 8. Through the setting of the sliding block 7 and the slide rail 8, it can not only guide the movement of the lifting plate 32 to prevent the lifting plate 32 from offsetting during the movement, but also prevent the lifting plate 32 from separating from the mounting bracket 2.

[0044] A gap is left between the mounting plate 4 and the sliding block 7 , and this arrangement facilitates the up and down movement of the lifting plate 32 and the mounting plate 4 .

[0045] In summary, the present invention reduces the inertia of the rotating part by mounting the lifting assembly 3 on the base 1 and then placing the rotating assembly 5 on the lifting assembly 3. According to the formula: angular acceleration = torque / inertia, it can be seen that reducing inertia can increase the acceleration during rotation and reduce the power requirement for the rotating part. The lifting assembly 3 still has sufficient power, so the increase in the load of the lifting assembly 3 has little effect on its speed.

[0046] At the same time, the power source of the rotating part is changed from a servo motor with a reducer to a direct drive of a DD motor 51. The DD motor 51 has the characteristics of high rigidity, high torque and high precision, and is very suitable for the working conditions of stacking loading, namely frequent starting and stopping, high acceleration and high repeat positioning accuracy.

[0047] All technical features in this embodiment can be freely combined according to actual needs.

[0048] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
