Description

Technical Field

[0001] This invention relates to the field of module extrusion technology, and more specifically, to a module extrusion device. Background Technology

[0002] With the rapid development of the new energy industry, the demand for energy storage systems, as core energy storage products, has surged. As the basic unit of an energy storage system, the production efficiency and quality of battery cell modules directly determine the performance of the system. In energy storage production lines, the steel strip installation process is a crucial step in the production of square battery cell modules. This process requires extruding the battery cell assembly to the required dimensions and then fitting it into the steel strip to securely bind the various units within the battery cell module. Existing steel strip installation methods have several problems. In current solutions, the battery cell assembly is first loaded onto the extrusion station via a robotic arm from the stacking station. Then, an existing extrusion press is used for extrusion shaping in all directions. After extrusion, the robotic arm picks up the battery cell assembly and places it onto the steel strip binding station. Therefore, existing module extrusion equipment has a complex overall structure, low production efficiency, increases the manufacturing cost of battery cell modules, has high equipment maintenance costs, lacks extrusion pressure feedback, and suffers from low extrusion accuracy and consistency. Therefore, we propose a new module extrusion equipment. Summary of the Invention

[0003] This invention provides a module extrusion device that solves the problems mentioned in the background art, such as the complex overall structure, low production efficiency, increased manufacturing cost of battery cell modules, high maintenance cost, lack of extrusion pressure feedback, low extrusion accuracy, and low consistency of existing module extrusion devices.

[0004] To achieve the above objectives, this solution provides a module extrusion device, including a base frame. Two operation screens are fixedly installed on the base frame, and several emergency stop and start buttons are also fixedly installed on the base frame. A stabilizing component is provided on the surface of the base frame, and two extrusion devices for extruding battery cell modules are symmetrically arranged on the base frame. The stabilizing component includes a base plate body disposed on the surface of the base frame. A lifting plate for driving the battery cell module upward is provided on the base plate body. A first rack plate is fixedly connected to the base plate body, and a fixed frame is fixedly connected to the lifting plate. A first rotating column is rotatably connected to the center of the fixed frame. A limiting frame for intermittently limiting the battery cell module is fixedly sleeved on the outside of the first rotating column. A first gear is fixedly sleeved on the outside of the first rotating column, and the first gear meshes with the first rack plate for transmission.

[0005] Several buffer pads are fixedly connected to the surface of the base plate body. The buffer pads are in intermittent contact with the bottom of the lifting plate. Several base plate fixing blocks are fixedly connected to the side of the base frame. The lifting plate is fixedly connected to the surface of the base plate fixing blocks. An installation rod is fixedly connected to the bottom of the base plate body. A linear bearing and a hydraulic damper are fixedly installed on the installation rod. Three lifting pads are fixedly connected to the top of the lifting plate.

[0006] A second rack plate is fixedly connected to the surface of the lifting plate, and a mounting block is fixedly connected to the surface of the base frame. A second rotating column is rotatably connected to the side of the mounting block, and a second gear and a third gear are fixedly connected to the second rotating column respectively.

[0007] A third rack plate is slidably connected to the base frame. The second rack plate meshes with the third gear for transmission, and the second gear meshes with the third rack plate for transmission.

[0008] Two support blocks are also fixedly connected to the base frame. Each of the two support blocks is fixedly connected to a fixing ring, and each of the two fixing rings is rotatably connected to a rotating toothed ring on its side.

[0009] Both the fixed ring and the rotating toothed ring have threaded sections on their inner walls, and the fixed ring and the rotating toothed ring are connected by a common threaded post inside.

[0010] A push plate is fixedly connected to the end of the threaded column, and the push plate is in intermittent contact with the battery cell module.

[0011] A lifting cylinder is fixedly connected to the surface of the base plate fixing block, and the output shaft of the lifting cylinder passes through the base plate and is fixedly connected to the bottom of the lifting plate.

[0012] A piston block is fixedly connected to the side of the first rack plate. A piston cavity is opened inside the lifting plate. A corrugated tube cavity is provided at the bottom of the lifting plate. The corrugated tube cavity is connected to the piston cavity. The piston block is slidably connected inside the piston cavity. A limit clamping block is slidably connected to the other end of the piston cavity. A return spring is fixedly connected between the limit clamping block and the inner wall of the piston cavity. The limit clamping block is in intermittent contact with the battery cell module.

[0013] The extrusion device includes a mounting frame fixedly installed on the surface of the base frame. A lifting electric cylinder is fixedly installed on the top of the mounting frame, and a movable frame is provided in the middle of the mounting frame. The output shaft of the lifting electric cylinder passes through the mounting frame and is fixedly connected to the top of the movable frame. A slide rail is fixedly connected to the side of the mounting frame, and a push plate is slidably connected on the slide rail. The push plate is fixedly connected to the side of the movable frame, and an extrusion electric cylinder is fixedly connected to the side of the movable frame. The output shaft of the extrusion electric cylinder passes through the push plate, and a pressure block is fixedly connected to the end of the extrusion electric cylinder.

[0014] Through the above technical solution, the module extrusion equipment provided by this solution, when in use: By setting up components such as a first rack plate, a fixed frame, a first rotating column, a limiting frame, and a first gear, in the initial state, the limiting frame abuts against the top of the battery cell module. During operation, the first rotating column drives the limiting frame to rotate, so that the protrusion on the back of the limiting frame abuts against the side of the battery cell module and limits it, forming a multi-directional fixation, which effectively prevents the battery cell module from shifting or tipping over during dynamic operation. By setting up components such as a second rack plate, mounting block, second rotating column, and second gear, when the battery cell module is extruded, a steel strip is fitted onto the battery cell assembly to ensure that the steel strip is taut and firmly fixed to the battery cell assembly and end plate, forming a prototype module. The extruder is then reset, the lifting mechanism is lowered, and the push plate is moved to push the battery cell module to the inspection area for preliminary manual inspection. The module is then sent to the next workstation via a conveyor line, and the above steps are repeated to complete the entire production cycle. Mechanical pushing avoids the risk of collision or drop of battery cell modules that may be caused by manual handling, and can effectively prevent physical damage, especially for precision components (such as lithium batteries).

Many specific details are set forth in the following description to provide a thorough understanding of this solution. However, this solution can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this solution. Therefore, this solution is not limited to the specific embodiments disclosed below.

[0029] In the description of this solution, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this solution and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this solution. The terms "first" and "second" are used to distinguish one element from another and do not have sequential or importance. Furthermore, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings indicate the same or similar elements, which will not be repeated here.

[0030] In this solution, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this solution based on the specific circumstances.

[0031] According to some embodiments of this solution, a module extrusion device is provided, for reference. Figure 1-11 As shown, the module extrusion equipment includes a base frame 1, on which two operation screens 101 are fixedly installed. The operation screens 101 are used to realize human-machine interaction, control equipment parameters, and monitor system status. It is worth noting that the specific model, working principle, and usage of the operation screens 101 are well known to those skilled in the art and will not be described in detail here. Several emergency stop and start buttons 102 are also fixedly installed on the base frame 1. The emergency stop and start buttons 102 are important safety devices used to control the operating status of equipment in industrial equipment, instruments, and other environments. It is worth noting that the specific model, working principle, and usage of the emergency stop and start buttons 102 are well known to those skilled in the art and will not be described in detail here.

[0032] The base frame 1 is provided with a stabilizing component 2. The stabilizing component 2 is used to clamp and fix the battery cell module when lifting it. The base frame 1 is also symmetrically provided with two extrusion devices 3 for extruding the battery cell module. The stabilizing component 2 includes a base plate body 201 provided on the surface of the base frame 1. The base plate body 201 is used to install the mechanical parts below. The base plate body 201 is provided with a lifting plate 202 for driving the battery cell module to rise. The base plate 201 is fixedly connected to a first rack plate 203, and the lifting plate 202 is fixedly connected to a fixing frame 204. The fixing frame 204 is used to install the mechanical parts below. The fixing frame 204 is rotatably connected to a first rotating column 205 in the middle. The first rotating column 205 is used to drive the parts below to rotate so as to clamp the battery cell module.

[0033] The first rotating column 205 is fixedly sleeved with a limiting frame 206 for intermittently limiting the battery cell module. It is worth noting that the first rotating column 205 and the limiting frame 206 are eccentrically arranged. The first gear 207 is fixedly sleeved on the outside of the first rotating column 205. The first gear 207 meshes with the first rack plate 203 to drive the first rotating column 205 to rotate and the limiting frame 206 to limit the battery cell module. It is worth noting that a protrusion is fixedly connected to one side of the limiting frame 206. When the limiting frame 206 rotates, it drives the protrusion to flip and limit one side of the battery cell module. The limiting frame 206 is surrounded by an arc-shaped surface so that it will not hinder the lifting and lowering of the battery cell module when rotating. Among them, a number of buffer pads 2011 are fixedly connected to the surface of the base plate main body 201. By setting the buffer pads 2011, buffering is achieved when the lifting plate 202 and the base plate main body 201 are in intermittent contact. A number of base plate fixing blocks 2012 are fixedly connected to the side of the base frame 1. By setting the base plate fixing blocks 2012, the base plate fixing blocks 2012 are used to install the parts mentioned below. The lifting plate 202 is fixedly connected to the surface of the base plate fixing blocks 2012.

[0034] The bottom of the base plate 201 is fixedly connected to a mounting rod. The mounting rod is used to install the mechanical parts that are raised below. A linear bearing 2013 and a hydraulic buffer 2014 are fixedly installed on the mounting rod. The linear bearing 2013 is used for lifting and guiding, and the hydraulic buffer 2014 and the buffer pad 2011 are used to buffer the lifting force, so that the battery cell assembly moves smoothly. The top of the lifting plate 202 is fixedly connected to three lifting pads 2021. The lifting pads 2021 are used to support and protect the battery cell assembly. The lifting plate 202 has a second rack plate 208 fixedly connected to its surface, and the base frame 1 has a mounting block 209 fixedly connected to its surface. The mounting block 209 is used to install the parts below. The mounting block 209 has a second rotating column 210 rotatably connected to its side. The second rotating column 210 is used to ensure effective force transmission. A second gear 211 and a third gear 212 are fixedly connected to the second rotating column 210. A third rack plate 213 is slidably connected to the base frame 1. When the device is started, the second rack plate 208 meshes with the third gear 212, and the second gear 211 meshes with the third rack plate 213, which in turn drives the mechanical parts below to move.

[0035] Two support blocks 214 are also fixedly connected to the base frame 1. The support blocks 214 are used to install the mechanical parts below. Each support block 214 is fixedly connected to a fixing ring 215. The fixing ring 215 provides support for the parts below. The sides of each fixing ring 215 are rotatably connected to a rotating gear ring 216. The rotating gear ring 216 provides support and drive for the parts below. The inner walls of both the fixing ring 215 and the rotating gear ring 216 are threaded. The fixing ring 215 and the rotating gear ring 216 are connected to a threaded post 217. When the rotating gear ring 216 rotates, the threaded post 217 advances inside the rotating gear ring 216. The end of the threaded post 217 is fixedly connected to a push plate 218, which pushes the push plate 218 to contact the battery cell module. Among them, a lifting cylinder 219 is fixedly connected to the surface of the base plate fixing block 2012. The output shaft of the lifting cylinder 219 passes through the base plate and is fixedly connected to the bottom of the lifting plate 202. The lifting cylinder 219 is used to drive the lifting plate 202 to rise. It is worth noting that the specific model, working principle and usage of the lifting cylinder 219 are well known to those skilled in the art, and will not be described in detail here. The first rack plate 203 is fixedly connected to a piston block 220 on its side. The lifting plate 202 has a piston cavity 221 inside. By setting the piston block 220 and the piston cavity 221, the bottom of the lifting plate 202 is provided with a corrugated tube cavity 224, which is connected to the piston cavity 221. By setting the corrugated tube cavity 224, the lifting plate 202 is prevented from being affected by the piston block 220 when it rises. It is worth noting that the corrugated tube cavity 224 is made of metal corrugated tube, so it will expand and contract when squeezed by the piston block 220, but will not deform when squeezed by gas. When the base plate body 201 moves, it drives the piston block 220 to slide inside the piston cavity 221. The other end of the piston cavity 221 is slidably connected to the limit clamping block 222. A return spring 223 is fixedly connected between the limit clamping block 222 and the inner wall of the piston cavity 221. By setting the limit clamping block 222 and the return spring 223, the piston block 220 presses the gas inside the piston cavity 221 toward the limit clamping block 222, so that the limit clamping block 222 rises and intermittently contacts the battery cell module.

[0036] The extrusion device 3 includes a mounting frame 301 fixedly mounted on the surface of the base frame 1. A movable frame 303 is provided in the middle of the mounting frame 301. The mounting frame 301 and the movable frame 303 are used to mount the part to be extruded below. A lifting cylinder 302 is fixedly mounted on the top of the mounting frame 301. The output shaft of the lifting cylinder 302 passes through the mounting frame 301 and is fixedly connected to the top of the movable frame 303. A slide rail 304 is fixedly connected to the side of the mounting frame 301. The slide rail 304 allows the part to slide on it. A push plate 305 is fixedly connected to the side of the movable frame 303. The push plate 305 is used to extrude the battery cell module. An extrusion cylinder 306 is fixedly connected to the side of the movable frame 303. The output shaft of the extrusion cylinder 306 passes through the push plate 305, and a pressure block 307 is fixedly connected to the end of the extrusion cylinder 306. The pressure block 307 is made of glass fiber material, which has the characteristics of being lightweight, high-strength, and corrosion-resistant. It is an excellent material for contacting the battery cell assembly. A lifting cylinder 302 and an extrusion cylinder 306 are used to drive the pressure block 307 to adjust its position and extrude.

[0037] Specifically, by setting the stabilizing component 2, when the robotic arm places the battery cell module on the lifting plate 202, the lifting plate 202 is initially located at position B (see attached diagram). Figure 11 The limiting frame 206 is located above the battery cell module and is set to contact the corner of the battery cell module. According to the specifications of the battery cell assembly, the lifting cylinder 219 is activated to align the height of the battery cell assembly and the pressure block 307. Then, the extrusion cylinder 306 is activated to push the pressure blocks 307 on both sides to move towards the center. By setting pressure sensors on the side of the mounting frame 301, the pressure sensors provide real-time feedback on the extrusion force, apply pressure stably and maintain it, and extrude the battery cell assembly to the predetermined size. The pressure block 307 is made of glass fiber material, which has the characteristics of being lightweight, high-strength, and corrosion-resistant, and is an excellent material for contact with the battery cell assembly. Simultaneously with the activation of the lifting cylinder 219, the output shaft of the lifting cylinder 219 drives the lifting plate 202 to rise. During the rise, the first gear 207 located outside the first rotating column 205 meshes with the first rack plate 203 on the base plate body 201, causing the first rotating column 205 to rotate 270 degrees on the fixed frame 204. This causes the protrusion on the back side of the limiting frame 206 to abut against the battery cell module. It is worth noting that when the first rotating column 205 rotates 270 degrees, the first gear 207 and the first rack plate 203 are exactly aligned. Simultaneously, the piston block 220 on the side of the first rack plate 203 slides into the piston chamber 221, pushing the gas inside the piston chamber 221 towards the limiting clamping block 222. This allows the limiting clamping block 222 to stably limit the battery cell module, significantly improving the stability and precision of the operation. In subsequent processes, the stable limiting can effectively prevent the battery cell module from shifting or vibrating, thus ensuring the processing quality. It is worth noting that the limiting clamping block 222 only extends a small portion to limit the lower part of the battery cell module. When the lifting plate 202 is at point A (see attached diagram) Figure 11 The lifting cylinder 302 and the extrusion cylinder 306 drive the pressure block 307 to extrude the battery cell. The robotic arm then puts a steel strip on the battery cell assembly to ensure that the steel strip is taut and firmly fixed to the battery cell assembly and the end plate, forming a module prototype. The extrusion device 3 is reset, and the lifting cylinder 219 drives the lifting plate 202 to point C. When the lifting plate 202 moves from point B to point C, the piston block 220 descends in the piston chamber 221 and begins to pump air, so that the gas no longer pushes the limit clamping block 222 to extend, causing the limit clamping block 222 to retract and reset. Simultaneously, the second rack plate 208 meshes with the third gear 212, driving the second rotating column 210 to rotate. While rotating, it also drives the second gear 211 to rotate. The second gear 211 meshes with the third rack plate 213, and the rotating gear ring 216 meshes with the third rack plate 213 and the threaded column 217, which meshes with the third rack plate 213, are threaded together. This allows the threaded column 217 to move forward inside the rotating gear ring 216, driving the push plate 218 forward to push the battery cell module. This causes the battery cell module to reach the inspection area, facilitating preliminary manual inspection. Subsequently, the module is sent to the next workstation, the lifting plate 202 returns to point B, the robotic arm loads the module, and the above steps are repeated to complete the entire production cycle. It is worth noting that the horizontal plane of the detection area is level with point C.

[0038] The preferred embodiments of this solution have been described in detail above with reference to the accompanying drawings. However, this solution is not limited to the specific details in the above embodiments. Within the scope of the technical concept of this solution, various simple modifications can be made to the technical solution, and these simple modifications all fall within the protection scope of this solution.

[0039] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this solution will not describe the various possible combinations separately.

[0040] Furthermore, various implementations of this solution can be combined in any way, as long as they do not violate the spirit of this solution, they should also be regarded as the content disclosed in this solution.
