DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1 to Figure 6 In an embodiment of the utility model, a storage device for a battery diaphragm roll 5 includes a support frame 66 and a storage frame 11.

[0029] The base 1010 includes a support plate 1111 with a horizontally arranged surface, and the support rod 641 is a rectangular parallelepiped. Universal wheels 1212 of the same model with a brake locking function are installed at the four corners of the lower surface of the support plate 1111. The universal wheels 1212 are installed on the support plate 1111 by welding.

[0030] The stand 22 is a rectangular parallelepiped as a whole, and mainly includes a horizontal bar 2121 and a vertical bar 2222. The horizontal bar 2121 and the vertical bar 2222 cross each other and are then welded together to form a plane grid-shaped stand 22. The stand 22 is vertically installed at one side edge of the support plate 1111, and the stand 22 cooperates with the support plate 1111 to form an L-shaped space, and the diaphragm roll 55 is placed in the L-shaped space. A reinforcing rib is welded and installed at the connection between the stand 22 and the support plate 1111 to improve the connection strength between the support plate 1111 and the stand 22.

[0031] Cantilever rods 33 are welded at each grid point of the stand 22, that is, at the intersection of the horizontal rod 2121 and the vertical rod 2222. Each cantilever rod 33 is parallel to each other and is horizontally upturned. The angle of the horizontal upturn is within a range of zero to five degrees, preferably two degrees. In order to facilitate the extraction of the diaphragm roll 55, the length of the cantilever rod 33 is set to three quarters of the length of the reel of the diaphragm roll 55. At the same time, in order to improve the strength of the cantilever rod 33, a reinforcing rib as a reinforcing member 44 is installed at the connection between the cantilever rod 33 and the stand 22. Reinforcing ribs are welded and installed on the four sides of the cantilever rod 33, and in order to reduce the interference of the reinforcing ribs on the diaphragm roll 55, the reinforcing ribs on the upper side of the cantilever rod 33 are set shorter, and the reinforcing ribs on the sides and the bottom are set longer.

[0032] When in use, first push the storage rack 1 to the corresponding place, and then lock each universal wheel 1212. Then, each diaphragm roll 55 is sequentially mounted on the cantilever rod 33, and for the sake of safety, it is usually installed one on each side to avoid excessive center of gravity shift. After all the cantilever rods 33 are installed on the diaphragm roll 55, open the universal wheel 1212, and push the storage rack 1 to the corresponding unloading position for unloading. Such reciprocating operation can realize the rapid batch transportation of diaphragm rolls 55.

[0033] After the storage rack 1 is filled with the membrane rolls 5, the storage rack 1 is pushed into the positioning frame 65. One side of the support plate 11 is pressed against the inner end surface of the positioning frame 65, and the telescopic motor serving as the positioning telescopic rod 651 starts to start, so that the motor shaft is extended to abut against the opposite side of the support plate 11, and the motor shafts of the two telescopic motors located on the same positioning frame 65 are extended to cooperate with the positioning frame 65 to form an annular frame that locks the storage rack 1 in the support frame 6.

[0034] After the storage rack 1 is fixed, the vertical telescopic rod 63, the longitudinal telescopic rod 621 and the transverse telescopic rod 611 start to move.

[0035] Two cross beams 61 arranged side by side are installed at the top of the support frame 6, and the two cross beams 61 and the support frame 6 cooperate to form a gantry structure. A transverse telescopic rod 611 is arranged on each of the two cross beams 61. The transverse telescopic rod 611 includes a first motor 6111 installed on the cross beam 61. A first screw rod 6112 is coaxially fixed to the motor shaft of the first motor 6111, and a first nut seat 61113 is coaxially threadedly connected to the first screw rod 6112. The first nut seat 61113 slides in the transverse direction under the drive of the first motor 6111.

[0036] A large gap is left between the two cross beams 61 for the movement of the hook 64. Two longitudinal beams 62 are overlapped on the two first nut seats 61113 at the same time, and a certain gap is also left between the two longitudinal beams 62 for the movement of the vertical telescopic rod 63. A longitudinal telescopic rod 621 is installed on both longitudinal beams 62. The longitudinal telescopic rod 621 includes a second motor 6211 fixedly installed at one end of the longitudinal beam 62, a second screw rod 6212 is coaxially fixed on the motor shaft of the second motor 6211, and a second nut seat 6213 is threadedly connected to the second screw rod 6212. Under the action of the second motor 6211, the second nut seat 6213 can move on the longitudinal beam 62 along the length direction of the longitudinal beam 62.

[0037] The vertical telescopic rod 63 is installed between the two longitudinal beams 62. The vertical telescopic rod 63 includes a telescopic motor fixedly connected to two second nut seats 6213 at the same time. The top end of the motor shaft of the telescopic motor extends downward and is fixedly connected with a hook 64. In order to increase the storage capacity, two positioning frames 65 are set in the support frame 6, and the corresponding two storage racks 1 are both located within the movement range of the vertical telescopic rod 63, the horizontal telescopic rod 611 and the longitudinal telescopic rod 621 to facilitate material retrieval.

[0038] When in use, the storage rack 1 is pushed into the positioning frame 65, and the storage rack 1 is fixed in the positioning frame 65 under the action of the positioning telescopic rod 651. Then, the positioning identification device installed on the lower side of the crossbeam 61 identifies the position of each diaphragm roll 5, and then transmits the identification result to the control terminal. The control terminal determines the diaphragm roll 5 that needs to be taken out according to the user's trimming, and then starts to drive the horizontal telescopic rod 611, the longitudinal telescopic rod 621 and the vertical telescopic rod 63 to move. First, the two first motors 6111 are started at the same time, and the two first nut seats 61113 start to move under the drive of the first motor 6111, so that the hook 64 moves between the two storage racks 1. Then the second motor 6211 drives the second nut seat 6213 to move, and the second nut seat 6213 drives the hook 64 to move to one end of the corresponding diaphragm roll 5; then the vertical telescopic rod 63 is driven, so that the bending part of the J-shaped hook 642 is lower than the lower end surface of the first diaphragm roll 5 reel; then the first motor 6111 is started again, and the bending part of the J-shaped hook 642 is moved to the bottom of the reel of the diaphragm roll 5 to be taken. Since the distance between adjacent diaphragm rolls 5 is large, the support rod 641 and the J-shaped hook 642 will not collide or rub with the diaphragm roll 5. The vertical telescopic rod 63 is started again, so that the J-shaped hook 642 hooks the two ends of the reel of the diaphragm roll 5, and then the diaphragm roll 5 is hooked from bottom to top, so that the reel of the diaphragm roll 5 and the cantilever rod 3 are separated, and the cantilever rod 3 is suspended in the shaft cavity of the diaphragm roll 5 reel. Finally, the first motor 6111 is used to reverse again to remove the diaphragm roll 5 from the cantilever rod 3 so that it can be used in subsequent processes. According to the above process, the corresponding diaphragm roll 5 can be taken.

[0039] After all the membrane rolls 5 on the storage rack 1 are removed, the locking function of the positioning telescopic rod 651 is released, the storage rack 1 is removed, and then the storage rack 1 is refilled with membrane rolls 5, and the storage rack 1 is locked in the positioning frame 65, and the subsequent hook 64 material removal work can be carried out. During the entire material removal process, multiple telescopic rods cooperate with each other to accurately remove the corresponding membrane rolls 5, effectively reducing the number of workers and greatly improving work efficiency.
