Description

Technical Field

[0001] The utility model relates to the field of battery production equipment, in particular to a lithium battery waterwheel conveying mechanism. Background Art

[0002] A battery cell refers to a single electrochemical cell containing positive and negative electrodes, and is the energy storage part of a battery. The quality of the battery cell directly determines the quality of the rechargeable battery. In the battery cell manufacturing process, the first step is to prepare the positive and negative electrode sheets. Subsequently, after the positive and negative electrode sheets are carefully stacked or wound, they are shaped by hot pressing to ensure the stability of their shape and structure. Next, the battery cell will go through processes such as transportation, packaging, and injection.

[0003] Among them, in the manufacturing process of the battery cell, the battery cell needs to be leveled and flipped during the loading process of the battery cell, so that the battery cell can be transported vertically and accurately moved to the predetermined position without deviation; placing the battery cells on the belt for transmission in sequence like the existing assembly line will increase the defective rate of the battery, and the battery cells are easy to be misplaced during movement and difficult to cooperate with the injection mechanism to complete the injection process of the battery cell. For example, the patent application document with application number CN201720600809.7 includes a battery cell flipping platform, a flip bracket and a battery cell flipping part fixed to the flip bracket. The flipping process is cumbersome, difficult and difficult to achieve simultaneous flipping of multiple battery cells, which greatly affects the production efficiency. At present, in the process of automatic assembly of battery modules, considering the assembly efficiency problem, it is generally adopted to load multiple battery cells at the same time, but in most cases, the battery cells are transported in a flat and side-by-side manner, so how to accurately position, arrange and erect the battery cell module has become a difficult problem faced in battery production. Utility Model Content

[0004] 1. Problems to be solved

[0005] The technical problem to be solved by the utility model is to provide a lithium battery water wheel conveying mechanism in view of the current status of the prior art.

[0006] (II) Technical solution

[0007] The utility model is realized by the following technical scheme: The utility model proposes a lithium battery water truck conveying mechanism, including: a battery cell unloading rack, in which a battery cell conveying belt and a battery cell clamp are installed. A clamp fixing opening and closing assembly is arranged on the battery cell unloading rack. A clamp positioning block, a connecting block, a battery cell clamp and a clamping plate are arranged on the battery cell clamp. The battery cell clamp is arranged on the connecting block and the clamping plate, and a spring is arranged between the connecting block and the clamping plate. A cam follower and a follower are arranged on the clamp fixing opening and closing assembly. The battery cell clamp completes the precise positioning of the battery cell clamp on the battery cell conveying belt through the positioning opening and clamping cylinder and the cam follower of the clamp fixing opening and closing assembly.

[0008] By adopting the above technical solution, the servo motor can provide a power source to drive the cell conveyor belt in the cell unloading rack to drive the cell clamp to the pre-set grabbing position of the material picking mechanism. Among them, the cell clamp adjusts the position of the cell clamp on the cell conveyor belt through the positioning clamp cylinder, the clamp positioning block and the cam follower of the clamp fixing opening and closing assembly, and completes the precise positioning of the cell clamp on the cell conveyor belt. When the cell clamp needs to be opened, the positioning clamp cylinder is pushed inward, and the spring between the connecting block and the clamping plate is stretched through the follower and the connecting block, and the cell clamp is opened accordingly; after the cell is placed, the positioning clamp cylinder retracts, and the spring is shortened accordingly, driving the cell clamp to the middle position to clamp the cell. At this time, the clamp has been positioned and installed in the cell conveyor belt, and the cell clamp with the cell clamped can be flipped from one end of the cell conveyor belt to the horizontal by driving the cell conveyor belt to move and transported along the cell conveyor belt to the other end of the cell conveyor belt. The utility model improves production efficiency and saves configuration cost of the device through such a design, facilitates the material taking mechanism to take materials from battery cells during battery manufacturing, and saves production time.

[0009] Furthermore, the connecting block provided on the battery cell clamp is a wedge-shaped block; when the battery cell clamp is at one end of the clamp fixing opening and closing assembly, the wedge-shaped block is combined with the follower on the positioning and clamping cylinder to form a cam structure.

[0010] By adopting the above technical solution, the wedge block can be combined with the follower on the positioning and clamping cylinder to form a cam structure to transmit the driving force of the positioning and clamping cylinder to achieve the effect of accurately opening or closing the battery cell clamping jaws.

[0011] Furthermore, a clamp buffer mechanism is provided on the clamp bottom plate of the battery clamp, and a clamp cam follower is installed on the clamp bottom plate. The clamp buffer mechanism includes a slide rail and a spring.

[0012] By adopting the above technical solution, the clamp buffer mechanism on the battery clamp ensures a certain positioning margin by using the slide rail and the spring, which can ensure that the battery clamp will not be stuck and complete the precise mechanical positioning within the range.

[0013] Furthermore, a transport plate is installed in the battery cell unloading rack; a groove is provided in the transport plate for the clamp cam follower to move in the transport plate. A drawstring connecting block is provided on the battery cell conveying drawstring, and the drawstring connecting block is connected to the clamp bottom plate pin.

[0014] By adopting the above technical scheme, a transport plate is provided in the battery cell discharge rack, a groove is provided in the transport plate for the clamp cam follower to move in the transport plate, and the pull belt connecting block is connected to the clamp bottom plate by pins, so that the battery cell clamp loaded with battery cells can be firmly fixed in the battery cell discharge rack and stably transported along with the battery cell conveying pull belt, thereby completing the cycle of the battery cell clamp.

[0015] Furthermore, the battery cell clamp is a rubber-coated battery cell clamp. The battery cell conveying belt is a loop-type trapezoidal tooth conveyor belt connected at the head and tail.

[0016] By adopting the above technical solution, the battery cell conveying belt is a circulating trapezoidal tooth conveyor belt to drive multiple battery cell clamps without slipping teeth, ensuring the accuracy and stability of battery transportation. By adopting an insulated rubber-coated battery cell clamp, the battery cell clamp can be prevented from being worn or deformed when clamping the battery cell, thereby protecting the battery cell during transportation.

[0017] Furthermore, support frames are provided at both ends of the battery cell discharge rack and a support cover is provided in the middle; a clamp is installed inside the support cover to fix the opening and closing assembly; the support cover and the support frame are used to provide support.

[0018] By adopting the above technical solution, a stable support effect can be provided for the battery cell unloading rack and the clamp fixing opening and closing components.

[0019] Furthermore, a barcode scanning gun is installed on the support cover.

[0020] By adopting the above technical solution, when the battery cell fixture loaded with battery cells passes under the barcode scanner, the barcode scanner scans the barcode on the battery cell to collect and record the battery cell related information. This information is used for tracing the battery production information.

[0021] (III) Beneficial effects

[0022] 1. The utility model realizes the step of flipping and erecting the battery cell while transporting the battery cell through the annular battery cell conveying belt and the battery cell clamp fixed on the battery cell conveying belt, eliminating the process of setting up an additional flipping device to complete the flipping of the battery cell during the transportation of the battery cell. The steps of transportation, flipping and erection are completed simultaneously in the transportation process, which reduces production time, speeds up production efficiency and saves the configuration cost of the device. At the same time, this mechanism has a wide range of applicability and can be adapted to a variety of material-retrieving mechanisms; it occupies a small space; it completes the transportation work in a highly automated manner, reducing labor costs; it is easy to operate and simple to maintain.

[0023] 2. The utility model adopts the design of a movable cam structure formed by a fixture positioning block on the battery cell fixture, a positioning and clamping cylinder, and a follower on the positioning and clamping cylinder, thereby completing the precise positioning of the battery cell fixture and moving it to a predetermined position, which facilitates the material taking mechanism of the battery cell in battery manufacturing and saves production time. The design of a movable cam structure formed by a combination of a connecting block on the battery cell fixture, a positioning and clamping cylinder, and a follower on the positioning and clamping cylinder can automatically clamp the battery cell in the battery cell fixture, and clamp the battery cell by the battery cell claws to keep the battery cell in an upright state, thereby preventing the electrolyte from leaking sideways due to different placement of the battery cells during transportation after liquid injection, and reducing the defective rate of finished batteries.

[0043] In this embodiment, the servo motor provides a power source to drive the cell conveying belt 2 in the cell unloading rack 1 to drive the cell clamp 3 to be transported to the grabbing position pre-set by the material taking mechanism.
