Description

[Technical field]

[0001] The invention relates to the field of automation equipment, and in particular to an automatic packaging angle pressing machine for lithium batteries. [Background technology]

[0002] At present, during the packaging process of lithium batteries, it is necessary to perform packaging angle pressing on lithium batteries. There will be stress concentration at the sharp corners of lithium batteries. After bending many times, it is easy to cause fatigue of the aluminum layer and produce cracks and damage. Once cracks and damage occur, water vapor can enter the battery and react with lithium hexafluorophosphate to produce gas, causing battery cell inflation, voltage reduction, capacity reduction, and even electrolyte leakage. For this reason, lithium batteries generally need to be angle pressed. The current angle pressing process is to manually place the battery corners on a cylinder angle pressing machine, and drive the cylinder to press the angle through manual alignment. This method is prone to deviations, including unstable manual holding, incorrect calibration, and easy damage to the battery when the angle is separated, resulting in deviations in the angle pressing operation. At the same time, the manual operation method also has the problem of mis-pressing, which threatens the safety of the operator. For this reason, an automatic positioning and safer angle pressing machine is needed. [Summary of the invention]

[0003] In order to solve the above problems, a lithium battery automatic packaging angle pressing machine is proposed, which can automatically position the angle pressing and make the angle pressing process safer.

[0004] A lithium battery automatic packaging angle pressing machine, the angle pressing machine includes a frame, a setting platform, a material placing device and an angle pressing device, the setting platform is arranged in the frame, the angle pressing device is slidably arranged on the setting platform, the material placing device is arranged on the setting platform, the material placing device includes a placing table and a placing table lifting mechanism, the placing table lifting mechanism is arranged on the setting platform, and a placing table is arranged above the placing table lifting mechanism.

[0005] The angle pressing device includes a front and rear moving platform and an angle pressing mechanism. The front and rear moving platform is slidably connected with the setting platform. A group of angle pressing mechanisms are slidably connected at each of the left and right ends of the front and rear moving platforms. The angle pressing mechanism includes left and right moving frames, up and down moving blocks, upper angle pressing pieces and lower angle pressing pieces. The left and right moving frames are slidably connected to the front and rear moving platforms through guide rail sliders; two groups of up and down moving blocks are also slidably connected on the left and right moving frames through guide rail sliders, and the two groups of up and down moving sliders are respectively provided with upper angle pressing pieces and lower angle pressing pieces.

[0006] By means of the above structure, the batteries that need to be packaged and pressed are placed on the placement table on the material placement device. The position of the placement table is fixed, and a placement slot that fits the size of the battery is provided on the top, that is, the battery position is fixed. Through the fixed working position, each structure only needs to be aligned at the origin, and then it can automatically run to the working position, that is, accurately adjust the distance between the two sets of pressing mechanisms, that is, slide left and right on the front and rear moving platforms for adjustment until the positions of the two corners of the battery are matched. After adjusting the distance between the two sets of pressing mechanisms, the height of the placement table is adjusted by the placement table lifting mechanism, and then the front and rear moving platforms slide to the pressing position relative to the setting platform, and the two sets of up and down moving sliders respectively drive the upper pressing piece and the lower pressing piece to press the corners of the battery, thereby realizing simultaneous pressing of the two parts of the battery that need to be pressed, achieving precise positioning and automatic pressing of the battery corners, and the pressing process does not require human participation, which is safer.

[0007] Preferably, the placement table lifting mechanism includes a lifting base, a lifting hinge, a lifting sliding block, a lifting sliding groove and a placement table setting plate. The lifting base and the placement table setting plate are arranged in parallel, and a lifting sliding groove is provided on one side of the upper end of the lifting base and the lower end of the placement table setting plate; and a lifting sliding block is provided in the lifting sliding groove.

[0008] There are two groups of lifting hinges, which cross each other and are hinged to each other in the middle to form an X-shaped hinge. One end of one group of lifting hinges is hinged to the lifting base, and the other end is hinged to the lifting sliding block of the lifting sliding groove of the placement table setting plate. One end of the other group of lifting hinges is hinged to the lifting sliding block of the lifting sliding groove of the lifting base, and the other end is hinged to the placement table setting plate.

[0009] It can be seen that the X-shaped hinge formed by the mutual hinged lifting hinges, when the two end angles above and below the X-shaped hinge are close to each other, the upper and lower heights of the X-shaped hinge become higher, and vice versa. One end of the lifting hinge is hinged to the lifting base or the placement table setting plate, and the other end is hinged to the lifting sliding block, providing a sliding range for the lifting hinge to approach, thereby achieving the relative distance on the rear end surface of the hinge to approach or move away, and realizing the relative height adjustment between the lifting base and the placement table setting plate.

[0010] Preferably, a threaded hole is provided on the lifting sliding groove member, a threaded rod is provided in the threaded hole, and a rotating member is provided on the threaded rod.

[0011] It can be seen that the threaded rod is driven by the rotating member, thereby driving the slider provided in the lifting and sliding groove member to move, thereby driving the placement table lifting mechanism to move up and down.

[0012] Preferably, a fixing device is also provided on the side of the material placement device, and the fixing device includes a fixing device setting table, a material front section fixing structure and a material rear section fixing structure, and the material front section fixing structure and the material rear section fixing structure are both arranged on the fixing device setting table.

[0013] It can be seen that by setting up a fixing device, the front and rear sections of the battery are fixed to prevent the battery from warping up during the angle pressing, which affects the angle pressing operation. By fixing, the angle pressing operation is ensured and the accuracy and completeness of the angle pressing are improved.

[0014] Preferably, the rear section fixing structure of the material comprises a positioning cylinder setting frame, a positioning cylinder and a fixing piece, wherein the positioning cylinder setting frame is arranged on the fixing device setting table, and a positioning cylinder with an output shaft pointing downward is provided, and a fixing piece is provided on the output shaft of the positioning cylinder.

[0015] It can be seen that the positioning cylinder drives the fixing parts to push up the rear section of the battery to prevent the battery from tilting during the angle pressing process, and at the same time fix the battery in position to ensure the smooth progress of the angle pressing operation.

[0016] Preferably, the front section fixing structure of the material comprises a rack, a gear, a fixed plate, a second cylinder and a rotating setting block, the gear and the fixed plate are coaxially rotatably connected to the rotating setting block, the output shaft of the second cylinder is provided with a rack, and the rack is meshed with the gear.

[0017] It can be seen that the rack is driven by the second cylinder, and thus the gear is meshed with the gear to achieve reciprocating rotation of the gear, which in turn drives the fixed plate to reciprocate, thereby achieving the change between the flat state and the pressing state, which facilitates the loading of the battery and the pressing and fixing after loading.

[0018] Preferably, the front-and-rear moving platform and the fixed platform are slidably connected via a front-and-rear moving cylinder, the front-and-rear moving cylinder is fixedly arranged on the fixed platform, and its output shaft is connected to the front-and-rear moving platform.

[0019] The front-rear moving platform and the angle pressing mechanism are slidably connected via a left-right moving cylinder; the left-right moving cylinder is fixedly arranged on the front-rear moving platform, and its output shaft is connected to the angle pressing mechanism.

[0020] The left-right moving frame and the up-down moving block are slidably connected via an up-down moving cylinder. The up-down moving cylinder is fixedly arranged on the left-right moving frame, and an output shaft thereof is connected to the up-down moving block.

[0021] It can be seen that by driving the sliding between the various components by means of cylinders, accurate control of the moving distance can be achieved, thereby improving the accuracy of the angle pressing operation.

[0022] Preferably, a control panel and a temporary placement platform are also provided on the rack.

[0023] It can be seen that the control panel makes it convenient for operators to adjust data and control the machine. The temporary placement platform makes it convenient for operators to temporarily place batteries, which provides convenience for operations and is conducive to improving production efficiency.

[0024] The present invention uses a placement table on a material placement device, and then places the battery on the placement table, and then fixes and positions the battery at a specified position through a material front section fixing structure and a material rear section fixing structure, and each cylinder adjusts the position and angle pressing pressure through a preset program, and the angle pressing device reaches the specified position to press the angle. Compared with the traditional method, the angle pressing position is more accurate, the product quality is high, and the preset program can be adjusted according to the demand to adjust the angle pressing position, and the adaptability is wide.

[0025] The present invention uses a placement table on the material placement device, does not require manual material holding, and is safer and more stable.
