Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary labor-saving devices, specifically a cylinder auxiliary balancing mechanism. Background Technology

[0002] In the gripper lifting mechanism of the YZ coordinate packing machine, a motor + reducer + synchronous belt structure is generally used to drive the heavy gripper frame to move up and down. Because the gripper and frame are relatively heavy, the motor and reducer are also under heavy load. Often, the normal operation of the mechanism can only be guaranteed by increasing the motor power and the reducer base model to provide greater torque. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a cylinder-assisted balancing mechanism, which effectively solves the problem of high energy consumption caused by large motor load.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a cylinder-assisted balancing mechanism, comprising a frame, a horizontal sliding plate slidably connected to the top of the frame via a slide rail slider, a crossbeam provided below the frame, a gripper frame fixedly connected to the crossbeam, and a lifting assembly provided between the horizontal sliding plate and the crossbeam.

[0005] Preferably, the lifting assembly includes a bracket fixed to the bottom of the horizontal slide plate, a crossbeam slidably connected to the side wall of the bracket via a slide rail slider, and two synchronous belts symmetrically arranged on both sides of the bracket, with the crossbeam fixed on the two synchronous belts.

[0006] Preferably, a servo motor is fixedly installed on the bracket, and a reducer is installed on the servo motor. The reducer is connected to two shafts via a chain and sprocket. The two shafts are installed vertically on the inner side of the bracket, and both ends of the upper and lower shafts extend to the outer side of the bracket and are connected to synchronous pulleys. The two synchronous belts are respectively connected to two sets of synchronous pulleys on the same side. The servo motor drives the sprocket to rotate the upper and lower shafts, which in turn drives the synchronous pulleys to rotate, realizing the transmission of the synchronous belts on both sides, so as to realize the lifting and lowering of the crossbeam.

[0007] Preferably, two mounting seats are symmetrically fixedly installed on the horizontal sliding plate, and a buffer cylinder is fixedly connected to each of the two mounting seats. The output ends of the two buffer cylinders are fixedly connected to the crossbeam.

[0008] Preferably, a support is fixedly installed on the top of the horizontal sliding plate, and an air storage bag is fixedly installed on the support. The air storage bag is connected to the buffer cylinder through a pipe.

[0009] Preferably, two buffer blocks are symmetrically fixedly connected to both the upper and lower sides of the synchronous belt.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention utilizes a servo motor and reducer to drive a synchronous belt via sprockets and chains. Simultaneously, the crossbeam is slidably connected to the side wall of the support via a slide rail slider. Driven by the rotation of the synchronous belt, the crossbeam and gripper frame can be raised and lowered. Through the cooperation of the air tank and buffer cylinder, the weight and inertia of the crossbeam are effectively balanced, significantly reducing the load on the servo motor, improving the acceleration and dynamic response speed of the mechanism, and significantly reducing operating energy consumption. The power of the servo motor is reduced from 3000W to 1.8W, thus ensuring the smooth operation of the entire lifting mechanism and improving packing efficiency. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Example 1, by Figure 1-3 The present invention relates to a cylinder-assisted balancing mechanism, comprising a frame 1, a horizontal slide plate 2 slidably connected to the top of the frame 1 via a slide rail slider, a crossbeam 10 provided below the frame 1, a gripper frame 11 fixedly connected to the crossbeam 10, and a lifting assembly provided between the horizontal slide plate 2 and the crossbeam 10.

[0020] The lifting assembly includes a bracket 8 fixed to the bottom of the horizontal slide plate 2, and a crossbeam 10 slidably connected to the side wall of the bracket 8 via a slide rail slider. Two synchronous belts 7 are symmetrically arranged on both sides of the bracket 8, and the crossbeam 10 is fixed on the two synchronous belts 7.

[0021] A servo motor 12 is fixedly installed on the bracket 8. A reducer is installed on the servo motor 12. The reducer is connected to two shafts via a chain and sprocket. The two shafts are installed vertically on the inner side of the bracket 8, and both ends of the upper and lower shafts extend to the outer side of the bracket 8 and are connected to synchronous pulleys. Two synchronous belts 7 are respectively connected to two sets of synchronous pulleys on the same side. The servo motor 12 drives the sprocket to rotate the upper and lower shafts, which in turn drives the synchronous pulleys to rotate, thereby realizing the transmission of the synchronous belts 7 on both sides to achieve the lifting and lowering of the crossbeam 10.

[0022] Two mounting bases 6 are symmetrically fixedly installed on the horizontal sliding plate 2. Each mounting base 6 is fixedly connected to a buffer cylinder 5, and the output end of each buffer cylinder 5 is fixedly connected to the crossbeam 10.

[0023] A support 3 is fixedly installed on the top of the horizontal sliding plate 2, and an air storage tank 4 is fixedly installed on the support 3. The air storage tank 4 is connected to the buffer cylinder 5 through a pipe.

[0024] The buffer cylinder 5 is pressurized on the load-bearing side, and the appropriate air pressure is adjusted to partially or completely offset the weight of the crossbeam 10. The other side is closed. The buffer cylinder 5 effectively offsets the impact inertia at the end of the lower stroke, ensuring that the mechanism stops smoothly. The air storage tank 4 stores a certain amount of compressed air, which can quickly replenish the gas in the buffer cylinder 5 to maintain a stable balance force when the mechanism rises, thereby offsetting the motion inertia. The servo motor 12 can achieve low-load or zero-load operation, thereby improving acceleration performance and dynamic response speed, and improving packing efficiency.

[0025] Two buffer blocks 9 are symmetrically fixedly connected to both the upper and lower sides of the synchronous belt 8;

[0026] In use, by setting the buffer block 9, the crossbeam 10 can be buffered.
