Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pole piece production, in particular to an avoidable belt pressing mechanism. Background Art
[0002] Figure 3 It is the main arrangement of the current belt pressing structure. A1 is the belt pressing platform, B1 is the belt pressing rod, C1 is the cylinder, and D1 is the material receiving box. The belt pressing rod B1 can be raised and lowered by the cylinder D1. When the cylinder D1 is extended, the belt pressing rod B1 is away from the belt pressing platform A1, and the battery electrode can be manually inserted from the gap between the belt pressing rod B1 and the belt pressing platform A1; when the cylinder D1 is retracted, the belt pressing rod B1 is close to the belt pressing platform A1, and the battery electrode under the belt pressing rod B1 is pressed. There is a vertical gap in the middle of the belt pressing platform A1, and the two belt pressing rods B1 are located on both sides of the gap. When two sections of battery electrodes need to be connected, the two sections of electrodes are cut and connected through the gap in the middle of the belt pressing platform A1, and the powder at the cut will fall into the material receiving box D1.
[0003] To ensure that the battery pole piece does not slide after being pressed, the pressure between the pressing rod B and the pressing platform A is generally required to be greater than 200N. For safety reasons, when the pressing rod B is lifted, the maximum gap with the pressing platform A needs to be less than 4mm ( Figure 4 ) to prevent people from reaching in and causing squeezing. Because the gap is very small, when conventional pole pieces are connected, it is necessary to manually insert the battery pole piece into the gap between the pressing rod B and the pressing platform A. This method is relatively convenient for pole pieces with a width of less than 900mm. However, for pole pieces with a width greater than 900mm, it is difficult for one person to manually insert the pole piece. Utility Model Content
[0004] In view of this, the utility model provides an avoidable belt pressing mechanism, which is applied to the device for connecting and pressing battery pole pieces, and can ensure convenient and fast connection of pole pieces with a width greater than 900 mm. The distance between the belt pressing rod and the belt pressing platform ensures that they cannot be touched by human hands, saving manpower and time costs for equipment operation.
[0005] The utility model adopts the following technical solutions to achieve the above technical effects:
[0006] An avoidable belt pressing mechanism comprises a belt pressing platform and a belt pressing rod, wherein the belt pressing rod is located above the belt pressing platform, and a distance greater than zero is provided between the belt pressing platform and the belt pressing platform; cylinders are provided on both sides of the belt pressing platform, and the ends of the telescopic rods of the cylinders are connected to the corresponding belt pressing rods;
[0007] The upper surface of the belt pressing platform is also provided with a belt threading chain, and the belt threading chain is perpendicular to the belt pressing rod; a sensor is supported by a protective cover above each belt pressing rod, and the sensor is connected to the driving circuit of the cylinder;
[0008] The connecting end of the wearing chain is provided with a strap-threading rod for connecting the battery pole piece.
[0009] Furthermore, the protective cover is fixed on the belt pressing platform and is erected above the belt pressing rod; the two sides of the protective cover are respectively an inlet and an outlet, wherein the outlet is connected to a protective cover flap via a hinge, and a position detection plate is provided on the inner side of the protective cover flap; when the protective cover flap closes the protective cover, the position detection plate faces the sensor.
[0010] Further, the height of the inlet is greater than the height of the outlet.
[0011] Furthermore, there are two of each of the belt pressing rod and the protective cover, and the two correspond to each other one by one.
[0012] Compared with the prior art, the beneficial effects achieved by the utility model are:
[0013] When a normal electrode passes through the belt pressing platform, it is necessary to disconnect the electrode from the belt threading rod, manually pass through the belt connecting platform, and then use the new belt threading rod to thread the electrode. The avoidable belt pressing structure equipped in this patent can ensure that the original equipment size does not change and meet safety requirements while allowing the electrode to pass through the belt pressing platform through the belt threading chain.
[0014] This method has two beneficial effects: 1. It saves time to disconnect the pole piece from the threading rod and manually pass it through the belt pressing platform. Through this mechanism, each time you pass a belt pressing platform, you can save about 10 minutes. 2. It saves labor costs. For pole pieces with a width of more than 900mm, or even up to 1400mm, it is difficult for a single person to manually pass the pole piece through the belt pressing platform, which is time-consuming and laborious. Therefore, for pole pieces with a wider width, it is usually completed by two people. Through this mechanism, a single person can shake the threading chain to make the pole piece pass through the belt pressing platform and complete the threading action.

[0020] Below, the utility model is further described in conjunction with the accompanying drawings.
[0021] See attached Figure 1 and Figure 2 In order to allow the pole piece to quickly pass through the pressing rod G when connecting the belt, this patent designs an automatic belt threading mechanism, which consists of a belt threading chain A and a belt threading rod B fixed on the belt threading chain A. The belt threading chain can be a standard chain, and the belt threading rod B is a round or rectangular rod. The chain is equipped with a separate driving mechanism, which can move the belt threading chain and fix the battery pole piece on the belt threading rod B. When the belt threading chain A moves, it drives the belt threading rod B to move, so that the battery pole piece quickly passes through the pressing rod G.
[0022] See attached Figure 2 , the left side is the feeding side, and the right side is the discharging side. In order to allow the threading rod B to pass through the pressing rod G, the minimum opening height of the pressing rod G must be greater than the outer diameter of the threading rod B. The height after opening is greater than 4mm, which does not meet the protection height of the pressing rod.
[0023] Therefore, a protective cover C is added outside the belt pressing rod G. The left opening of the protective cover is slightly higher, so that the chain can drive the belt pressing rod to pass through the left side of the protective cover. The left opening is far away from the belt pressing rod G, and a person's hand can reach into the left side of the protective cover, but cannot touch the belt pressing rod G, so the belt pressing rod G cannot cause danger to the person's hand.
[0024] Due to space reasons, the belt pressing platform H cannot be larger, so the inlet and outlet of the pressure bar protective cover C cannot be made into a structure with the same size. This mechanism adds a protective cover flap D to the right side of the protective cover close to the outlet. This mechanism is connected through a hinge F, so that the protective cover flap D can only be flipped to the right to adapt to the direction of the belt threading rod driven by the chain. Hinge F has a certain damping force. When the belt threading rod B drives the pole piece from left to right through the pressure bar rigid protective cover C, the belt threading rod or the protective cover flap D opens, and the pole piece can pass through the pressure bar protective cover. The protective cover flap D is equipped with a sensor E to detect the position. When the protective cover flap D is detected to be in place, the belt pressing rod G can rise and fall to perform the belt pressing function; when the protective cover flap D is detected to be out of place, the belt pressing rod G cannot move, and the program and the mechanical structure are interlocked at this time. When the protective cover flap D is not flipped, the gap with the belt pressing platform is ≤4mm, which meets the safety distance.
[0025] The feeding and discharging structures of the belt pressing shield in this patent are different. The feeding shield is a large opening shield, which allows the belt threading rod and fingers to be inserted, but the palm cannot pass through, so the fingers cannot touch the belt pressing rod. The discharging is a flap with hinges. When the belt is threaded through the chain, the belt threading rod touches the flap, and the flap will open to allow the belt threading rod to pass. When normal operation is required, the flap is manually closed and the sensor detects that it is in place.
[0026] It should be understood that the above description of the specific implementation methods of this patent is only an exemplary description listed to facilitate ordinary technicians in the field to understand the patent scheme, and does not imply that the scope of protection of this patent is limited to these individual examples. Ordinary technicians in this field can fully understand the technical scheme of this patent and, without any creative work, obtain more specific implementation methods by combining technical features, replacing some technical features, adding more technical features, etc. to the examples listed in this patent. All these specific implementation methods are within the scope of the claims of this patent. Therefore, these new specific implementation methods should also be within the scope of protection of this patent.
[0027] In addition, for the purpose of simplifying the description, this patent may not list some common specific implementation schemes, which are naturally conceivable to ordinary technicians in this field after understanding the technical solution of this patent. Obviously, these solutions should also be included in the scope of protection of this patent.
