Detailed Description

The present invention will be further described with reference to the following specific embodiments.

Example 1

As shown in fig. 1 and fig. 2, the vertical lifting apparatus for moving and transporting a lithium battery separator according to the embodiment includes a base 1, a support base 2, a lifting mechanism 3, and a bearing support 6. Wherein, elevating system 3 is located between base 1 and supporting seat 2, and the both ends of diaphragm roller are erect respectively on corresponding bearing support 6. The lifting mechanism 3 drives the supporting seat 2 to move up and down, and further drives the diaphragm roller on the bearing supporting piece 6 to move up to reach the next station to prepare for the next process. The lifting mechanism 3 can realize automatic upward movement of the diaphragm roller, manual transfer is not needed, labor intensity is greatly reduced, and working efficiency is improved.

As shown in fig. 4, the lifting mechanism 3 includes a driving unit 31 and two sets of support arm assemblies, the support arm assemblies in a single set are arranged in a crossed manner and hinged to each other, and the specific hinge point can be selected according to actual requirements. The driving unit 31 is disposed on the base 1, and the driving unit 31 drives the supporting arm assembly, so as to drive the supporting seat 2 to ascend. Specifically, the single support arm assembly includes a first support arm 32 and a second support arm 33, the hinge point of the two support arms is located at the lower part of the middle of the support arm, and a connecting rib is arranged between the two support arm assemblies. Wherein, one end of the first supporting arm 32 is rotatably connected to the supporting base 2, the other end is in sliding fit with the base 1, one end of the second supporting arm 33 is in sliding fit with the supporting base 2, and the other end is rotatably connected to the base 1.

In this embodiment, the driving unit 31 is a hydraulic cylinder, and the output end of the hydraulic cylinder is connected to the connecting rib of the first supporting arm 32. During operation, the hydraulic cylinder operates to drive the lower end of the first support arm 32 to slide along the base 1. Since the first support arm 32 and the second support arm 33 are hinged to each other. At this time, the upper ends of the second support arms 33 slide along the support base 2, and the corresponding ends of the two support arms move away from or close to each other, thereby completing the entire lifting operation. In addition, the base 1 of the embodiment is provided with the pulley 11, so that the whole lifting device can be conveniently moved.

Since the center of the driving unit 31 is shifted during the ascending process, the position of the diaphragm roller in the horizontal direction is changed, which is not beneficial to the synchronization of the next process (the next process has certain requirements on the arrangement position and direction of the diaphragm roller). In addition, in the actual operation process, the situation that the two ends of the diaphragm roller are reversely arranged often occurs. At this point, the equipment needs to be readjusted so that the diaphragm rollers are in the correct position. In order to make the adjustment operation of the diaphragm roller more convenient and faster, in this embodiment, the supporting seat 2 is provided with a rotating beam 4, two ends of the rotating beam 4 are provided with displacement compensation mechanisms 5, and the displacement compensation mechanisms 5 are connected with a bearing support member 6. Wherein, the displacement compensation mechanism 5 compensates and adjusts the horizontal displacement generated by the bearing support 6 in the ascending process. The supporting seat 2 is connected with the rotary beam 4 through a rotary supporting bearing 7. When the two ends of the diaphragm roller need to be replaced or small-angle adjustment is needed, only the rotating beam 4 needs to be pushed, and the rotating beam 4 can drive the bearing support piece 6 to rotate, so that the direction of the diaphragm roller can be adjusted.

As shown in fig. 5, the displacement compensation mechanism 5 includes a driving shaft 51 and a driven shaft 52, wherein one end of the driven shaft 52 is fixed to the load-bearing support 6, and the driving shaft 51 rotates to drive the driven shaft 52 to move along the length direction of the rotating beam 4. In this embodiment, two driving gears 53 are disposed at two ends of the driving shaft 51, two driven shafts 52 are disposed, and each driven shaft 52 is provided with teeth 54 engaged with the driving gears 53. Of course, the driven shaft 52 may also need to be a rack.

When the load-bearing support member 6 is driven by the lifting mechanism 3 to ascend to the next station, the center of the load-bearing support member 6 will deviate. At this time, the driving shaft 51 rotates to move the load bearing support 6 in the horizontal direction by the driven shaft 52, thereby compensating for the displacement generated during the ascent. The data of the specific compensation can be adjusted according to the implementation condition so as to meet the requirement of the next working procedure. In the whole displacement compensation operation process, the bearing support pieces 6 on the two sides of the rotating beam 4 move synchronously, the distance between the two bearing support pieces 6 is kept unchanged, and the diaphragm roller is always clamped between the two bearing support pieces 6, so that the falling phenomenon cannot occur.

In order to stably support the membrane roller by the load-bearing support 6 and prevent the membrane roller from falling off during the transfer process (placing the membrane roller on the load-bearing support 6). As shown in fig. 3, the load-bearing support 6 of the present embodiment includes a first notch 61, a second notch 62, and a third notch 63, wherein the first notch 61 supports an end of the diaphragm roll, the second notch 62 and the third notch 63 are respectively located on both sides of the first notch 61, and the height of the first notch 61 is higher than that of the other two notches. Specifically, first notch 61 be the arc notch, the radian of this arc notch and the outer circumference looks adaptation of diaphragm roller tip can guarantee like this that the contact of diaphragm roller and notch is more stable. In addition, the connection surface between the first notch 61 and the second notch 62, and the connection surface between the first notch 61 and the third notch 63 are an inclined surface. Like this, when transporting, if the diaphragm roller is not aimed at completely with first notch 61, at this moment, the notch of both sides can carry out the backstop to the diaphragm roller of landing, prevents that the diaphragm roller from droing completely, causes the diaphragm damage.

The present invention and its embodiments have been described above schematically, and the description is not limited thereto, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching of the present invention, without departing from the inventive spirit of the present invention, the person skilled in the art should also design the similar structural modes and embodiments without creativity to the technical solution, and all shall fall within the protection scope of the present invention.
