Description

Technical Field

[0001] The invention relates to the technical field of trays, and in particular to a damage-resistant and adjustable clamping tray for equidistant battery cells. Background Art

[0002] The battery cell pallet is designed to protect the battery cells and prevent them from being damaged by collisions during transportation, and to serve as a supporting structure during transportation. Since the sizes and shapes of battery cells of different specifications vary greatly, the height of the pallet increases accordingly to meet the storage requirements of taller battery cells. When these pallets are not in use, they are usually stacked up and down in the workshop for ready use at any time. However, the number of taller pallets that can be stacked in a limited space is limited, which increases the storage cost of the pallets. At the same time, the pallets are prone to shaking and collapsing during the stacking and transportation process, which in turn causes damage to the pallets. Furthermore, when the pallets are used or stored for a long time, dust is easily adhered to the surface. When the pallets are carrying battery cells, dust is easily adhered to the surface of the battery cells, causing the battery cells to be contaminated and requiring additional costs to clean them.

[0003] At the same time, when the battery cells are stacked on pallets for transportation, if they encounter unexpected collisions or vibrations during transportation, the pallets may shake. This shaking may cause the battery cells on the pallet to be squeezed, increasing the risk of damage or even breakage of the battery cells. Once the battery cells are broken, the electrolyte inside them may leak, and the leaked electrolyte may flow to other intact battery cells, causing them to be contaminated as well. Summary of the invention

[0004] In order to overcome the shortcomings of existing battery cell trays, such as high storage cost, unstable stacking and easy collapse, easy dust accumulation on the surface which pollutes the battery cells, and shaking during transportation which causes damage to the battery cells, the present invention provides an anti-breakage adjustable equidistant battery cell clamping tray.

[0008] As a further preferred solution, it also includes protective strips; each baffle is fixed with a plurality of protective strips that reduce the contact area with the battery cell, and the protective strips are made of rubber material.

[0009] As a further preferred solution, it also includes a push rod; a plurality of push rods are fixedly connected to the tray; the airbags and the push rods are used to buffer the battery cells during transportation; and each push rod is directly opposite to the air hole above.

[0015] The present invention has the following advantages: the present invention realizes that the overall height of the pallet is reduced by pushing the limit frame to slide downward on the pallet, so that more pallets can be stacked in the same storage space, and the risk of shaking and collapsing during transportation is reduced by reducing the overall height of the pallet;

[0016] By overlapping and accommodating two adjacent baffles, the area of ​​the bottom plate carrying the battery cells is covered, thereby reducing the dust covering the bottom plate during long-term use and storage, and preventing the dust from contaminating the battery cells;

[0031] A damage-resistant and adjustable equidistant battery cell clamping tray, such as Figure 1-Figure 7 As shown, it includes a tray 1 and a bottom plate 2; the bottom plate 2 is slidably connected to the tray 1;

[0032] It also includes a limit frame 3, a baffle 4 and a locking block 103; the limit frame 3 is slidably connected to the tray 1; two first slide grooves 2002 are provided on the bottom plate 2; two second slide grooves 3001 are provided on the limit frame 3; a number of baffles 4 are slidably connected between the bottom plate 2 and the limit frame 3; two rotating rods 4001 are provided on each baffle 4, and each rotating rod 4001 slides on the corresponding first slide groove 2002 and second slide groove 3001; a card slot is provided on the limit frame 3; four locking blocks 103 are plugged into the tray 1; each locking block 103 is plugged into and matched with the card slot on the adjacent limit frame 3.

[0033] It also includes an airbag 101; a plurality of air holes 2001 in a rectangular array are provided on the bottom plate 2; a plurality of liquid guide grooves 2003 are provided on the bottom plate 2, and each air hole 2001 is located in an adjacent liquid guide groove 2003; the airbag 101 is fixedly connected to the upper side of the tray 1; a plurality of exhaust ports 10102 are provided on the airbag 101, and each exhaust port 10102 is connected to an adjacent air hole 2001; the upper side of the airbag 101 is fixedly connected to the bottom plate 2.

[0034] It also includes a baffle 102 ; each baffle 4 has a baffle 102 fixedly connected to the front and rear sides.

[0035] It also includes protection strips 104; a plurality of protection strips 104 are fixedly connected to the left and right sides of each baffle 4, and the protection strips 104 are made of rubber.

[0036] It also includes a push rod 201; a plurality of push rods 201 are fixedly connected to the tray 1; each push rod 201 is directly opposite to the air hole 2001 above.

[0037] It also includes a collection box 202; each top rod 201 is provided with a guide cavity 20101; the collection box 202 is detachably connected to the tray 1; the collection box 202 is fixedly connected to each top rod 201, and the collection box 202 is communicated with each guide cavity 20101.

[0038] Each protection strip 104 is arranged to be tilted backwards to guide the gas to flow toward the rear side, prevent the gas from flowing directly upwards, and avoid the gas mixed with dust from blowing directly toward the workers.

[0039] A soft sealing sheet is provided on the lower side of each baffle 4 , and the sealing sheet is always in contact with the bottom plate 2 to prevent the electrolyte leaking from the damaged battery cell 5 from flowing to the intact battery cell 5 through the gap between the baffle 4 and the bottom plate 2 , thereby improving the protection of the intact battery cell 5 .

[0040] Each baffle 102 is made of rubber. When the baffle 4 is stored and forms an angle with the bottom plate 2 , the deformable baffle 102 always keeps in contact with the bottom plate 2 , so as to keep the front and rear sides of the baffle 4 sealed.

[0041] Before stacking the produced battery cells 5, the worker pulls the baffle plate 4 to slide on the first slide groove 2002 and the second slide groove 3001, and then adjusts the distance between two adjacent baffle plates 4, so as to adapt to the width of the battery cell 5 and place it between the two baffle plates 4. In this way, the battery cell 5 is reciprocated and placed between the baffle plate 4 and the bottom plate 2. Finally, the battery cells 5 are stacked on the pallet 1, and the pallet 1 is stacked and transported by the transport device. Since the pallet 1 is stored in an up-and-down stacking manner when not in use, when the battery cells 5 to be stacked are high, the overall height of the pallet 1 used is also increased. It is difficult to stack more pallets 1 in the limited storage space, and the higher pallets 1 are stacked during the stacking and transportation process. The center of gravity is unstable and it is easy to collapse. In order to avoid this phenomenon, when the pallet 1 is not in use, the worker pushes the limit frame 3 to slide downward on the pallet 1, thereby lowering the overall height of the pallet 1, so that more pallets 1 can be stacked in the same storage space. Lowering the overall height of the pallet 1 reduces the risk of shaking and collapse during transportation. At the same time, before the limit frame 3 moves downward, the worker pushes the rotating rod 4001 on the lower side of all the baffles 4 to slide to the right on the first slide groove 2002 for a distance, and then the worker presses the limit frame 3 to slide downward, so that the two rotating rods 4001 rotate and slide on the first slide groove 2002 and the second slide groove 3001 respectively, so that all the baffles 4 gradually fall downward to the left, so that two adjacent baffles 4 are like Figure 4 As shown, they are overlapped with each other in sequence, thereby covering the area of ​​the bottom plate 2 used to carry the battery cell 5, reducing the dust covering the bottom plate 2 during long-term use and storage, and preventing the dust from contaminating the battery cell 5. In this process, a rubber baffle 102 is used to cover the angle formed by the baffle 4 and the bottom plate 2 after it is tilted when the baffle 4 is tilted for storage, so as to prevent the outside air from carrying dust and blowing toward the bottom plate 2.

[0042] In the process of using the bottom plate 2 and the baffle plate 4 to carry and fix the battery cell 5, in order to reduce the phenomenon that the dust on the baffle plate 4 adheres to the side of the battery cell 5, the protective strip 104 arranged on the baffle plate 4 is in contact with the battery cell 5 to reduce the contact area with the battery cell 5. At the same time, in order to further reduce the pollution of the dust to the battery cell 5, the limit frame 3 is pulled upward to move back to the initial height, and then the baffle plate 4 is unfolded as shown in FIG. Figure 2 As shown, at this time, each row of air holes 2001 is located between two adjacent baffles 4, and then the worker presses the limit frame 3 to move downward, thereby driving the baffle 4 and the bottom plate 2 to move downward, thereby squeezing the airbag 101 to contract, so that the gas in the airbag 101 is first discharged from the exhaust port 10102, and then sprayed out from the air hole 2001, and then directly blown to the side of the baffle 4, so that the dust attached to the side of the baffle 4 is blown away. At the same time, in order to avoid blowing directly to the worker, the worker can also press the limit frame 3 to move downward for a distance, so that the baffle 4 is tilted to the right as a whole, and finally the worker presses the limit frame 3 and the bottom plate 2 downward at the same time. When the baffle 4 is stored, the baffle 4 falls to the left and covers the bottom plate 2, and the right side of the baffle 4 faces upward and contacts with the outside air, and the dust impurities in the air are removed. It is easy to fall on the right side of the baffle 4, so when the baffle 4 is tilted to the right at this time, the right side of the baffle 4 faces downward, so that the gas ejected from the air hole 2001 is blown to the baffle 4, and the inclined baffle 4 is used to guide the gas to prevent the gas from flowing directly upward. At the same time, the right side of the inclined baffle 4 faces the airflow, which increases the windward area of ​​the baffle 4 and improves the cleaning effect of the right side of the baffle 4. The limit frame 3 and the bottom plate 21 are pressed back and forth 3 times in the above manner, and the baffle 4 is blown and cleaned multiple times, thereby ensuring that the area for storing the battery cells 5 is in a relatively clean state. When the blowing and cleaning is completed, the worker places the battery cells 5 on the bottom plate 2, and finally the worker pushes the locking block 103 through the tray 1 and inserts it into the slot of the limit frame 3, thereby fixing the limit frame 3, and then stacking and transporting the tray 1.

[0043] It is also considered that after the battery cells 5 are placed on the pallet 1, they are stacked and stacked for transportation. When the pallet 1 encounters an unexpected collision or vibration during transportation, the mutual shaking and squeezing of the pallet 1 causes the battery cells 5 to be compressed, which can easily cause the battery cells 5 to be broken and unusable. In the process of the bottom plate 2 compressing the airbag 101, when the airbag 101 is compressed to half, the air hole 2001 is blocked by the push rod 201, so that the gas in the airbag 101 cannot be discharged from the air hole 2001, so that some gas remains in the airbag 101. At this time, the locking block 103 is inserted into the slot on the limit frame 3 to lock it. Since the pallet 1 is transported in a stacked manner, when the pallet 1 is shaken and squeezed, the airbag 101 with gas remaining at the bottom is squeezed by the upper and lower pallets 1, so that its sides are deformed in four directions: forward, backward, left and right, respectively, thereby buffering and protecting the battery cells 5 on the bottom plate 2, avoiding the battery cells 5 from being damaged, and improving the protection capability of the battery cells 5 during transportation.

[0044] It is also considered that when the battery cell 5 is shaken and bumped during transportation, when the battery cell 5 bumps against the tray 1 and leaks, the leaked electrolyte is likely to flow to the adjacent intact battery cell 5 on the upper side of the bottom plate 2, causing the battery cell 5 to be contaminated. In order to avoid this phenomenon, when a single battery cell 5 leaks, the electrolyte flows to the air hole 2001 on the upper side of the bottom plate 2, and the soft sealing sheet on the lower side of the baffle 4 is used to intercept the electrolyte first to prevent the electrolyte from flowing to the adjacent intact battery cell 5. At the same time, through the bottom The liquid guide groove 2003 arranged on the plate 2 allows the electrolyte to flow to the air hole 2001. At this time, because the top rod 201 is pushed into the air hole 2001, and the top rod 201 is provided with a guide cavity 20101, the electrolyte passes through the air hole 2001 and the guide cavity 20101 and finally flows to the collection box 202, so that the electrolyte cannot flow along the upper side of the bottom plate 2 to the adjacent battery cell 5, ensuring that other intact battery cells 5 are not contaminated. Finally, the workers remove the collection box 202 to centrally clean the electrolyte inside it.

[0045] Example 2

[0046] On the basis of Example 1, Figure 1 , Figure 5 and Figure 8 As shown, it also includes a push plate 301; a push plate 301 is slidably connected to the inside of the bottom plate 2 through a spring; an air groove 2004 is opened on the bottom plate 2; a first rectangular groove 10101 is opened on the airbag 101, and the air groove 2004 is directly opposite to the first rectangular groove 10101 up and down; a second rectangular groove 30101 is opened on the push plate 301.

[0047] In the initial state, the air groove 2004 and the first rectangular groove 10101 are separated by the push plate 301, and the second rectangular groove 30101 is staggered with the air groove 2004. When the pallet 1 is transported to the destination, the battery cell 5 on the pallet 1 needs to be taken out. In order to facilitate the worker to take out the battery cell 5, the worker first loosens the locking block 103, and then pushes the push plate 301 to move to the right, thereby connecting the air groove 2004, the first rectangular groove 10101 and the second rectangular groove 30101 to each other. At the same time, the worker presses the limit frame 3 to move downward, thereby driving the baffle 4 and the bottom plate 2 to move downward, so that the airbag 101 with some gas remaining in it shrinks. At this time, the gas is discharged through the first rectangular groove 10101, the second rectangular groove 30101 and the air groove 2004, so that the push rod 201 passes through the air hole 2001 and extends from the lower side of the bottom plate 2, and then the battery cell 5 on the bottom plate 2 is pushed upward, so that the upper side of the battery cell 5 is higher than the upper side of the baffle 4. At this time, it is more convenient for workers to take the battery cell 5.
