Description

Technical Field

[0001] The utility model relates to the technical field of diaphragm roll transportation, in particular to a battery diaphragm roll storage rack. Background Art

[0002] The raw material diaphragm used in the processing of lithium-ion batteries is processed in the form of rolled diaphragm rolls. The diaphragm rolls need to be cut into multiple small rolls by a slitting device and then rolled up. Then they are placed on a temporary storage rack to be transferred to the packaging process. The well-packed diaphragm rolls are sent to the lithium-ion battery production plant. In order to ensure that the cleanliness inside the workshop is not damaged, the unpacking work needs to be completed in a special unpacking room; the unpacked diaphragm rolls are moved to the designated location inside the production workshop through the transfer rack. The transfer rack can be used in both diaphragm production workshops and lithium-ion production workshops.

[0003] In current production operations, because the diaphragm rolls are relatively light, production workers are accustomed to picking up the diaphragm rolls with their bare hands. There are no special temporary storage and transfer racks for the diaphragms. The transfer volume is small, and the diaphragms need to be picked up frequently, which increases movement and handling waste, and therefore needs to be solved urgently. Utility Model Content

[0004] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides a battery diaphragm roll storage rack. The utility model can realize the rapid batch transportation of diaphragm rolls.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A battery diaphragm roll storage rack comprises a base movable on the ground, a vertical frame mounted on the base, a cantilever rod passed through the shaft cavity of the diaphragm roll to hang the diaphragm roll on the vertical frame mounted on the vertical frame, and the cantilever end of the cantilever rod is horizontally upward; a reinforcing member for improving the connection strength is installed at the connection between the cantilever rod and the vertical frame; the center of gravity of the vertical frame after being fully hung with diaphragm rolls is located within the support range of the base.

[0007] As a further solution of the utility model: the reinforcement member is a reinforcement rib, and the reinforcement ribs on the same cantilever rod are arranged in sequence on the outer side of the cantilever rod around the circumference of the cantilever rod.

[0008] As a further solution of the utility model: the length of the reinforcing ribs on both sides of the cantilever rod is greater than the length of the reinforcing ribs on the upper side of the cantilever rod.

[0009] As a further solution of the utility model: the stand comprises a vertically arranged cross bar and a horizontally arranged vertical bar, and each cross bar and each vertical bar are cross-intersected and fixedly connected to each other to form a plane grid-like stand.

[0010] As a further solution of the utility model: the cantilever rod is fixedly connected at the intersection of the horizontal rod and the vertical rod.

[0011] As a further solution of the utility model: the cantilever rods are arranged parallel to each other, and the straight-line distance between adjacent cantilever rods is greater than twice the outer roll of the diaphragm roll.

[0012] As a further solution of the utility model: the horizontal upward angle of the cantilever rod is 2 degrees.

[0013] As a further solution of the utility model: the base includes a support plate and universal wheels arranged at the four corners of the lower surface of the support plate.

[0014] As a further solution of the utility model: the vertical support plate surface of the stand is fixedly connected to one side edge of the support plate, and reinforcing ribs are also installed between the stand and the support plate.

[0015] As a further solution of the utility model: an L-shaped space is formed between the stand and the support plate, and each cantilever rod is arranged in the L-shaped space.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model uses a movable base, which can improve the convenience of carrying the diaphragm roll. The use of a horizontally upturned cantilever rod can prevent the diaphragm roll from sliding off the cantilever rod during transportation while hanging the diaphragm roll, thereby improving the stability of transportation. At the same time, the use of reinforcements can increase the strength of the connection between the cantilever rod and the stand, prevent the connection between the cantilever rod and the stand from deformation due to vibration during load-bearing and transportation, and further improve the stability of transportation. The coordination between the base, the stand and the cantilever rod can effectively improve the uniform speed and single transportation volume of the diaphragm roll.

[0018] 2. The utility model installs a cantilever rod at the connection between the horizontal rod and the vertical rod. The arrangement of the cross intersection can provide a more solid support for the cantilever rod compared to a single horizontal rod or a single vertical rod, avoiding deformation of the horizontal rod or the vertical rod due to weak support, and improving the firmness and stability of the support.

[0023] 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.

[0024] See also Figure 1 to Figure 3 In an embodiment of the utility model, a battery diaphragm roll storage rack includes a base 1, a stand 2 and a cantilever rod 3.

[0025] like Figure 1 As shown, the base 1 includes a support plate 11 with a horizontally arranged plate surface, and the support rod is a rectangular parallelepiped. Universal wheels 12 of the same model with a brake locking function are installed at the four corners of the lower plate surface of the support plate 11. The universal wheels 12 are installed on the support plate 11 by welding.

[0026] like Figure 1 and Figure 2 As shown, the stand 2 is a rectangular parallelepiped as a whole, and mainly includes a horizontal bar 21 and a vertical bar 22. The horizontal bar 21 and the vertical bar 22 cross each other and are then welded together to form a plane grid-shaped stand 2. The stand 2 is vertically installed at one side edge of the support plate 11, and the stand 2 cooperates with the support plate 11 to form an L-shaped space, and the diaphragm roll 5 is placed in the L-shaped space. A reinforcing rib is welded and installed at the connection between the stand 2 and the support plate 11 to improve the connection strength between the support plate 11 and the stand 2.

[0027] Cantilever rods 3 are welded at each grid point of the stand 2, i.e., at the intersection of the horizontal rod 21 and the vertical rod 22. Each cantilever rod 3 is parallel to each other and is horizontally tilted upward, and the angle of horizontal tilting is within a range of zero to five degrees, preferably two degrees. In order to facilitate the extraction of the diaphragm roll 5, the length of the cantilever rod 3 is set to three quarters of the length of the reel of the diaphragm roll 5. At the same time, in order to improve the strength of the cantilever rod 3, reinforcing ribs are installed at the connection between the cantilever rod 3 and the stand 2 as reinforcement members 4. Reinforcing ribs are welded and installed on the four sides of the cantilever rod 3, and in order to reduce the interference of the reinforcing ribs on the diaphragm roll 5, the reinforcing ribs on the upper side of the cantilever rod 3 are set shorter, and the reinforcing ribs on the sides and the bottom are set longer.

[0028] When in use, first push the storage rack to the corresponding place, and then lock each universal wheel 12. Then, each diaphragm roll 5 is sequentially mounted on the cantilever rod 3, 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 3 are installed on the diaphragm roll 5, open the universal wheel 12, and push the storage rack to the corresponding unloading position for unloading. Such reciprocating operation can realize the rapid batch transportation of diaphragm rolls 5.
