Description

Technical Field

[0001] The present application relates to the field of lithium battery production equipment, and in particular to a lithium battery production injection equipment. Background Art

[0002] During the production of soft-pack lithium batteries, electrolyte needs to be injected into the soft pack. In order to better achieve the injection of electrolyte, people have developed a lithium battery vacuum injection system for the injection of electrolyte into soft-pack lithium batteries. During the injection process, the soft pack needs to be kept in an open state. The current common injection method is automated injection equipment, which generally uses turntable equipment, that is, different process equipment is set at different positions of the turntable, such as injection, sealing, etc.

[0003] The automated liquid injection equipment generally includes a liquid injection processing box and a vacuum treatment box. The vacuum treatment box and the liquid injection box are integrated. The main steps are: first place the soft package on the material rack, and then place the material rack in the vacuum treatment box for vacuum treatment. Since the vacuum treatment box and the liquid injection processing box are integrated and connected, the door of the vacuum treatment box is opened at this time, and the operator takes the material rack in the vacuum treatment box to the turntable position in the liquid injection processing box through the glove opening on the liquid injection processing box, and places the soft packages on the positioning table on the turntable in turn. After the turntable rotates, the soft packages on the positioning table are rotated in turn to the liquid injection station and the sealing station in the liquid injection processing box.

[0004] With regard to the above-mentioned related technologies, since the operator's operating position is limited, the operator can only operate through the glove port. Since the glove port is generally facing the turntable to facilitate the operator to load materials, the vacuum processing box is generally located on the side of the glove port, and there is a certain distance between the vacuum processing box and the glove port, which makes it more difficult for the operator to take the material rack from the vacuum processing box through the glove port. Summary of the invention

[0005] In order to facilitate operators to take materials, the present application provides a lithium battery production injection equipment.

[0006] The present application provides a lithium battery production injection equipment, which adopts the following technical solution:

[0007] A lithium battery production liquid injection equipment comprises a liquid injection processing box and a vacuum treatment box, wherein the vacuum treatment box is fixed on the side wall of the liquid injection processing box, a box door for opening and closing the vacuum treatment box is slidably connected in the liquid injection processing box, and the sliding of the box door can make the vacuum treatment box connected to the liquid injection processing box, a turntable is rotatably connected in the liquid injection processing box, a positioning platform is provided on the turntable, a glove opening is provided on one side of the liquid injection processing box, two waist-shaped rails arranged in parallel are fixedly installed in the liquid injection processing box, the waist-shaped rails are arranged vertically and the length direction of the waist-shaped rails is arranged along the thickness direction of the box door, a moving car is provided on the waist-shaped rails, the moving car can move along the path direction of the waist-shaped rails, and the moving car can move from the vacuum treatment box to the glove opening and The movable frame is provided with a limit assembly for limiting the material rack from leaving the movable frame; the movable frame is provided with a driving wheel and a pressure wheel, the movable frame is slidably connected with a slide plate, the pressure wheel is rotatably connected to the slide plate, the movable frame is provided with a pressure spring for driving the pressure wheel to press the outer wall of the waist-shaped track, the driving wheel is rotatably connected to the movable frame, the movable frame is provided with a power part for driving the driving wheel to rotate, the waist-shaped track is provided with a waist-shaped groove for the driving wheel to be inserted so that the driving wheel can move along the path direction of the waist-shaped track; the waist-shaped track is provided with a fracture opening for the box door to slide through.

[0008] By adopting the above technical scheme, when in use, the mobile cart is located in the vacuum treatment box, at this time, the material rack containing the material is placed on the mobile seat of the mobile cart, and then vacuum treatment is carried out. After the treatment is completed, the box door is opened, and then the driving wheel is driven to rotate by the power part, thereby driving the mobile cart to move along the waist-shaped track. After the mobile cart moves to between the glove opening and the positioning table, the operator can place the material on the material rack on the positioning table; this scheme uses the mobile cart to transport the material from the vacuum box to between the glove opening and the positioning table, which is convenient for the operator to take the material, and is simple and convenient; and the waist-shaped track is set because the vacuum treatment of the material and the placement of the material on the positioning table both require a certain amount of time, so two mobile carts can be set on the waist-shaped track, so that the material placement work can be carried out while the material vacuum treatment work is carried out, thereby improving work efficiency.

[0009] Optionally, the waist-shaped track is provided with a filling block 1 and a filling block 2 for filling the fracture, the filling block 1 is used to fill the fracture on the upper side of the waist-shaped track, and the filling block 2 is used to span the fracture on the lower side of the waist-shaped track; a conveying mechanism is provided in the liquid injection processing box, and an electromagnet is fixedly connected to the output end of the conveying mechanism, and the electromagnet is used to adsorb the filling block 1, and the moving mechanism can embed the filling block 1 into the fracture or move the filling block 1 to the liquid injection processing box through the electromagnet, and a step surface is provided on the side wall of the fracture on the upper side of the waist-shaped track to limit the filling block 1 from moving downward from the fracture; the filling block 2 is slidably arranged on the waist-shaped track, and the filling block 2 slides to span the fracture, and a driving component 1 for driving the filling block 2 to slide is provided on the waist-shaped track.

[0010] By adopting the above technical scheme, due to the existence of the box door and the waist-shaped track needs to pass through the sliding path of the box door, the waist-shaped track needs to be provided with a fracture so as not to affect the sliding of the box door. However, due to the existence of the fracture, the mobile vehicle may be unstable when moving through the fracture. Therefore, filling block 1 and filling block 2 are provided, so that when the box door is opened, the filling block 1 and the filling block 2 can fill the fracture on the upper side and the lower side of the waist-shaped track respectively, so as to ensure the smooth operation of the mobile vehicle; when filling the fracture on the upper side of the waist-shaped track, the electromagnet on the conveying mechanism is used to adsorb the filling block 1, and then the filling block 1 is driven to move by the conveying mechanism so that the filling block 1 fills the fracture on the upper side of the waist-shaped track, and then the electromagnet is powered off and the conveying mechanism is used to move the electromagnet away. When the vacuum processing box needs to be closed, the conveying mechanism and the electromagnet are used to move the filling block 1 to the liquid injection processing box; when filling the fracture on the lower side of the waist-shaped track, the driving component is used to drive the filling block 2 to slide so that the filling block 2 spans the fracture on the lower side of the waist-shaped track.

[0011] Optionally, a sleeve is fixedly connected to the side wall of the waist-shaped track, and an extension rod is slidably inserted in the sleeve. The end of the extension rod away from the sleeve is fixedly connected to the filling block 2. The driving component 1 includes an inflatable cylinder and a piston rod. The inflatable cylinder is fixed to the side wall of the waist-shaped track, and the inflatable cylinder is connected to the sleeve through an air pipe. One end of the piston rod is slidably inserted in the inflatable cylinder, and the filling block 1 is embedded in the fracture to push the piston rod to move. The inflatable cylinder is provided with a reset spring for resetting the piston rod.

[0012] By adopting the above technical solution, when driving the filling block 2 to move, when the conveying mechanism drives the filling block 1 to embed into the fracture on the upper side of the waist-shaped track, the filling block 1 will push the piston rod to move and inject air into the sleeve, thereby driving the extension rod to move under the action of air pressure, and then driving the filling block 2 to slide, and the reset spring can facilitate the reset of the piston rod and the extension rod; the driving component 1 utilizes the force of the filling block 1 embedded in the fracture on the upper side of the waist-shaped track to drive the extension rod to slide. The structure is simple and convenient, and reduces the operating steps, ensuring that the filling block 1 and the filling block 2 can fill the fracture at the same time.

[0013] Optionally, a shifting mechanism is provided in the liquid injection processing box, and the shifting mechanism is used to move the material rack on the movable seat toward the direction close to the positioning platform; the shifting mechanism includes a base, a cylinder and a support plate, the cylinder is vertically arranged, and the fixed end of the cylinder is slidably connected to the base along the shortest connecting line direction of the two waist-shaped rails, and the base is provided with a driving component 2 for driving the cylinder to move, the telescopic end of the cylinder is fixedly connected to the support plate, and the movable seat is provided with a through slot for the support plate to pass through, and the support plate passes through the through slot to support the material rack.

[0014] By adopting the above technical solution, after the mobile vehicle transports the material rack to between the glove opening and the positioning table, the limit of the material rack by the limit component is cancelled, and then the material rack is lifted up by the cylinder and the support plate, and then the drive component 2 is used to drive the material rack to move toward the positioning table. Therefore, when the operator places the material on the material rack on the positioning table, the operator does not need to move the arm frequently and over a long distance, which is convenient for the operator to operate.

[0015] Optionally, the limit assembly includes a latch, a limit spring and a guide ball; a slot for inserting the latch is opened on the material rack, and the latch is C-shaped. One end of the latch is used to pass through the movable seat and be inserted into the slot, and the other end of the latch is fixedly connected to the guide ball; a push plate is fixedly connected to the support plate, and during the vertical movement of the support plate, the push plate pushes the guide ball to move so that the latch disengages from the slot; the limit spring is used to drive the latch to be inserted into the slot.

[0016] By adopting the above technical solution, when the material rack is placed on the moving seat, the latch is pulled so that the latch will not block the material rack. After the material rack is placed on the moving seat, the latch is released, and under the action of the limit spring, the latch is inserted into the slot to limit the material rack. After the moving seat moves to the cylinder position, the cylinder telescopic rod is extended to allow the support plate to pass through the through slot to lift the material rack. Before the support plate contacts the material rack, the push plate contacts the guide ball to push the latch to move so that the latch is out of the slot, thereby releasing the limit of the material rack, and then the cylinder and the drive assembly are used. After the material rack is moved to the appropriate position, the operator places the materials on the material rack on the positioning table. After the processing is completed, the cylinder is used to drive component 2 to reset the material rack. During this process, the push plate contacts the guide ball first and pushes the latch so that the latch no longer blocks the material rack from being placed on the positioning table. As the cylinder continues to shorten, the push plate disengages from the guide ball, and under the action of the limit spring, the latch is reset and plugged into the slot, thereby limiting the material rack so that the material rack will not fall when the mobile vehicle drives the material rack to move to the upper side of the waist-shaped track.

[0017] Optionally, a limiting groove for inserting the supporting plate is provided at the bottom of the material rack.

[0018] By adopting the above technical solution, the stability of the material rack can be maintained when the shifting mechanism drives the material rack to move.

[0019] In summary, this application includes the following beneficial technical effects:

[0020] 1. In this application, the material is transported from the vacuum box to between the glove opening and the positioning table by a mobile vehicle, which is convenient for operators to take the material. The waist-shaped track is set because it takes a certain amount of time to vacuum process the material and place the material on the positioning table. Therefore, two mobile vehicles can be set on the waist-shaped track, so that the material can be placed while the material can be vacuum processed, thereby improving work efficiency.

[0021] 2. This application uses a shifting mechanism to move the material rack to a suitable position. When the operator places the material on the material rack on the positioning table, the operator does not need to move the arm at a high frequency and over a long distance, which facilitates the operator's operation.
