Description

Technical Field

[0001] The utility model relates to the technical field of battery manufacturing, in particular to a battery positive electrode forming device. Background Art

[0002] The main structure of the existing energy-type battery carbon positive electrode is a carbon package mode, and the carbon positive electrode is mainly manufactured by using a carbon particle extrusion molding process. In an existing positive electrode forming device for extruding and molding a carbon particle carbon package, it includes a cloth feeding mechanism and a material pressing mechanism. Among them, the cloth feeding mechanism includes a cloth feeding sleeve and a positioning column. One end of the cloth feeding sleeve is docked with the battery case to input carbon particles into the battery case by using the cloth feeding sleeve. The positioning column is inserted into the battery case so that a space for accommodating carbon particles is formed between the inner wall of the battery case and the positioning column. Of course, the shape of this space matches the shape of the formed carbon positive electrode (the carbon positive electrode is tubular). After the carbon particles enter the battery case from the cloth feeding sleeve, due to the different distribution amounts of the carbon particles in each area in the circumferential direction of the positioning column during the input process, there are differences in the accumulation amounts of the carbon particles in each area in the circumferential direction of the positioning column. After the carbon particles are compacted, the entire carbon positive electrode will have uneven carbon particle density distribution, affecting the discharge performance of the carbon positive electrode. Also, after the carbon particles enter the battery case and are accumulated in the space between the positioning column and the battery case, it is necessary to use a material pressing rod to press the carbon particles for a long time to eliminate the voids between the carbon particles and make the carbon particles compacted. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a battery positive electrode forming device, in which the density distribution of carbon particles is uniform, the forming quality of the carbon positive electrode is good, and the forming efficiency is high.

[0004] To achieve this purpose, the utility model adopts the following technical solutions:

[0005] A battery positive electrode forming device provided includes:

[0006] A workbench, the workbench includes a platform, a vibrator, and a turntable for installing a battery case. The turntable is rotatably arranged on the platform to drive the battery case to rotate around the axis of the battery case. The vibrator is connected to the turntable to make the turntable generate mechanical vibration;

[0007] A cloth feeding mechanism, the cloth feeding mechanism is arranged above the workbench in a liftable manner, and the cloth feeding mechanism corresponds to the position of the turntable. The cloth feeding mechanism is used to input carbon particles into the battery case;

[0008] A material pressing member, the material pressing member is arranged above the cloth feeding mechanism in a liftable manner. The material pressing member is used to press the carbon particles.

[0009] Further, the workbench further includes a clamping assembly disposed on the turntable, and the clamping assembly is used for clamping the battery housing.

[0010] Further, the cloth feeding mechanism includes a cloth feeding sleeve and a positioning column. One end of the cloth feeding sleeve in the axial direction forms a feeding port, and the other end forms a discharging port. A storage bin is formed between the feeding port and the discharging port. The positioning column is coaxially installed at the discharging port, and a first material dropping channel is formed between the positioning column and the side wall of the discharging port. One end of the positioning column extends in a direction away from the storage bin, so that the positioning column can be inserted into the battery housing.

[0011] Further, one end of the positioning column passes through the discharging port and extends into the storage bin.

[0012] Further, the cloth feeding mechanism further includes a guiding member coaxially installed at the discharging port. A second material dropping channel is formed between the guiding member and the side wall of the discharging port, and one end of the guiding member extends into the storage bin.

[0013] Further, the cloth feeding sleeve includes a sleeve and a cover plate disposed at the bottom end of the sleeve. The feeding port and the storage bin are disposed on the sleeve, and the discharging port is disposed on the cover plate. Part of the cover plate can be inserted into the battery housing.

[0014] Further, the cover plate includes an inner plate and an outer plate coaxially arranged. The outer plate is in a ring structure. The inner plate is disposed on the inner ring side of the outer plate and is spaced from the outer plate.

The positioning column is fixed on the inner wall of the feeding port through the connecting members, and an avoidance notch for passing through the connecting members is disposed on the pressing member.

[0018] Advantages of the present utility model: By rotatably arranging a turntable on the platform, when feeding the material, the turntable drives the battery housing to rotate, so that the carbon particles falling into the battery housing are more evenly distributed in the circumferential direction of the battery housing, avoiding uneven stacking thickness of the carbon particles in the circumferential direction of the battery housing due to factors such as different resistances and flow rates when the carbon particles fall from the feeding mechanism. At the same time, after the carbon positive electrode is formed and before the positioning post is separated from the carbon positive electrode, the turntable can be rotated to make the positioning post and the carbon positive electrode rotate relative to each other, playing a role in shaping the carbon positive electrode, so that the side of the carbon positive electrode close to the positioning post is well separated from the positioning post, avoiding scratching the side of the carbon positive electrode close to the positioning post during the rising process of the positioning post. This method is beneficial to improving the forming quality of the carbon positive electrode. Moreover, by arranging a vibrator, the vibrator is used to vibrate the battery housing to eliminate the gaps between the carbon particles, making the stacking of the carbon particles more compact, shortening the working time of the pressing member, and improving the forming efficiency of the carbon positive electrode.

Detailed Embodiments

[0025] To make the technical problems solved, the technical solutions adopted, and the technical effects achieved by the present utility model clearer, the technical solutions of the present utility model will be further described below with reference to the drawings and through specific embodiments.

[0026] AsFigure 1 As shown in the figure, a battery positive electrode forming device provided by the present utility model is used to form a carbon positive electrode in a battery case 5. The battery positive electrode forming device includes a workbench 2, a cloth feeding mechanism 3 and a pressing member 4. Among them, the workbench 2 is used to place the battery case 5. The workbench 2 includes a platform 21, a turntable 22 and a vibrator (not shown in the figure). The turntable 22 is rotatably arranged on the platform 21. A motor drivingly connected to the turntable 22 is also arranged on the platform 21, and the motor is used to drive the turntable 22 to rotate around its own axis. The vibrator is arranged on the platform 21. The vibrator is a prior art. The vibrator is connected to the turntable 22 so that the vibrator can transmit mechanical vibration to the turntable 22 and enable the turntable 22 to generate mechanical vibration. The battery case 5 is installed on the turntable 22, and the rotation of the turntable 22 drives the battery case 5 to rotate synchronously, so that the battery case 5 can rotate along its own axis. Under the action of the vibrator, the mechanical vibration is transmitted to the battery case 5 through the turntable 22, so that the battery case 5 can generate mechanical vibration. The cloth feeding mechanism 3 is used to input carbon particles into the battery case 5. The carbon particles are the raw materials for forming the carbon positive electrode. The cloth feeding mechanism 3 is vertically movably arranged above the workbench 2, and the position of the cloth feeding mechanism 3 corresponds to that of the turntable 22. The cloth feeding mechanism 3 is located directly above the turntable 22. The bottom end of the cloth feeding mechanism 3 is used to selectively connect with the battery case 5. That is, when starting to feed cloth, the cloth feeding mechanism 3 descends so that the bottom end of the cloth feeding mechanism 3 is connected to the battery case 5, so as to enable the cloth feeding mechanism 3 to input carbon particles into the battery case 5. After the cloth feeding is completed, the cloth feeding mechanism 3 ascends so that the cloth feeding mechanism 3 is separated from the battery case 5. The pressing member 4 is used to compact the carbon particles input into the battery case 5. The pressing member 4 is vertically movably arranged above the cloth feeding mechanism 3. The pressing member 4 is vertically arranged, that is, the axis of the pressing member 4 extends along the vertical direction (the Z direction shown in the figure). When pressing, the pressing member 4 descends, and the bottom end of the pressing member 4 passes through the cloth feeding mechanism 3 and inserts into the battery case 5, and the carbon particles are compacted by the extrusion of the bottom end of the pressing member 4. After the pressing is completed, the pressing member 4 ascends and is separated from the battery case 5.

[0027] It can be understood that by rotatably arranging the turntable 22 on the platform 21, when feeding cloth, the turntable 22 drives the battery case 5 to rotate, so that the carbon particles falling into the battery case 5 are more evenly distributed in the circumferential direction of the battery case 5, and it is avoided that the carbon particles falling from the cloth feeding mechanism 3 are uneven in the stacking thickness in the circumferential direction of the battery case 5 due to factors such as different resistances and flow rates. In addition, by arranging the vibrator, the vibrator is used to make the battery case 5 generate vibration to eliminate the gaps between the carbon particles, make the stacking of the carbon particles more compact, and shorten the working time of the pressing member 4.

[0028] Specifically, the workbench 2 further includes a clamping assembly 23. The clamping assembly 23 is used to fix the battery housing 5. The clamping assembly 23 includes two clamping blocks arranged at intervals, and the two clamping blocks are used to clamp the battery housing 5. Correspondingly, the battery housing 5 has a cylindrical structure, and an arc surface matching the battery housing 5 is formed on the side of the clamping block close to the battery housing 5. At least one of the clamping blocks is connected to a driving device, and the driving device is a cylinder, a lead screw mechanism or a linear motor, etc. The driving device is used to drive the two clamping blocks to approach or move away from each other, so as to clamp and release the battery housing 5.

[0029] Specifically, the battery positive electrode forming device further includes a frame 1, and the frame 1 is used to install the cloth feeding mechanism 3 and the pressing member 4. The frame 1 includes a base 10, a first driving assembly 11, columns 12, a cross beam 13 and a second driving assembly 14. The base 10 is installed on the platform 21 or on other installation bases. The columns 12 are vertically arranged on the base 10. Two cross beams 13 are arranged on the columns 12, and the cloth feeding mechanism 3 and the pressing member 4 are respectively installed on the columns 12 through the cross beams 13, so that the cloth feeding mechanism 3 and the pressing member 4 can be suspended above the battery housing 5. The first driving assembly 11 is arranged on the columns 12, and the first driving assembly 11 is connected to the pressing member 4 to drive the pressing member 4 to move up and down. The first driving assembly 11 is an existing lead screw-slider mechanism, that is, the first driving assembly 11 is threadedly connected to the cross beam 13 through a lead screw, and the motor drives the lead screw to rotate, thereby driving the cross beam 13 to move vertically on the columns 12. Of course, in some embodiments, the first driving assembly 11 can also be a cylinder, a hydraulic cylinder, a linear motor, etc. The second driving assembly 14 is arranged on the cross beam 13, and the output end of the second driving assembly 14 is connected to the cloth feeding mechanism 3 to drive the cloth feeding mechanism 3 to move up and down. The second driving assembly 14 is a cylinder, a hydraulic cylinder or a linear motor, etc. In this embodiment, the second driving assembly 14 is a cylinder, its fixed end is installed on the cross beam 13, and its telescopic end is fixedly connected to the cloth feeding mechanism 3.

[0030] Refer to Figures 1 to 3As shown, the fabric mechanism 3 includes a fabric sleeve 31, a flow guide 32, and a positioning post 33. The fabric sleeve 31 is vertically arranged, and its axis extends along the vertical direction. Along the axis direction of the fabric sleeve 31 (the Z direction shown in the figure), the top end of the fabric sleeve 31 forms a feed inlet 3111, and the bottom end of the fabric sleeve 31 forms a discharge outlet 3121. A storage bin 3112 is formed between the feed inlet 3111 and the discharge outlet 3121. The two opposite ends of the storage bin 3112 are respectively communicated with the feed inlet 3111 and the discharge outlet 3121. The feed inlet 3111 is in a flared shape, with the large end of the feed inlet 3111 located above and the small end located below, so as to facilitate the user to put carbon particles into the battery housing 5 through the feed inlet 3111. The storage bin 3112 serves to temporarily store carbon particles, so that the storage bin 3112 can store a certain amount of carbon particles to ensure that the carbon particles can be continuously input into the battery housing 5. During fabric feeding, the carbon particles sequentially pass through the feed inlet 3111, the storage bin 3112, and the discharge outlet 3121 and enter the battery housing 5. The function of the positioning post 33 is to position the carbon positive electrode formed in the battery housing 5. The positioning post 33 is coaxially installed at the discharge outlet 3121, that is, the positioning post 33 is coaxial with the discharge outlet 3121. The diameter of the positioning post 33 is smaller than the diameter of the discharge outlet 3121, so that a space is formed between the positioning post 33 and the discharge outlet 3121 to form a first material dropping channel. The bottom end of the positioning post 33 extends in a direction away from the storage bin 3112, that is, the bottom end of the positioning post 33 extends downward. When the fabric mechanism 3 is connected to the battery housing 5, the positioning post 33 can be inserted into the battery housing 5, and the positioning post 33 is coaxial with the battery housing 5. The carbon particles fall from the first material dropping channel, that is, the carbon particles fall from around the positioning post 33. The carbon particles accumulate in the space between the positioning post 33 and the inner wall of the battery housing 5. Correspondingly, the carbon positive electrode formed by the accumulation of carbon particles is tubular. In this embodiment, the cross-sectional shapes of the first material dropping channel and the carbon positive electrode are the same.

[0031] The flow guide 32 serves as a flow guiding function. The flow guide 32 is coaxially installed at the discharge outlet 3121. In this embodiment, the flow guide 32 is located at one end of the discharge outlet 3121 facing the storage bin 3112, and the positioning post 33 is located at one end of the discharge outlet 3121 facing the battery housing 5. The top end of the flow guide 32 extends into the storage bin 3112, and the top end of the flow guide 32 is spherical. A second material dropping channel 34 is formed between the flow guide 32 and the side wall of the discharge outlet 3121. The second material dropping channel 34 has the same size as the first material dropping channel and the two are communicated with each other. Under the action of the flow guide 32, the carbon particles in the storage bin 3112 enter the second material dropping channel 34 from around the flow guide 32 and enter the battery housing 5 through the first material dropping channel.

[0032] In another embodiment, the flow guiding member 32 and the positioning post 33 can also be provided as an integral structure. That is, the fabric mechanism 3 includes a positioning post 33. The positioning post 33 is coaxially installed at the discharge port 3121. The bottom end of the positioning post 33 extends into the battery housing 5, and the top end of the positioning post 33 extends into the storage bin 3112. The carbon particles in the storage bin 3112 fall through the gap between the positioning post 33 and the side wall of the discharge port 3121.

[0033] Specifically, along the circumferential direction of the discharge port 3121, a plurality of connecting members 3122 are spaced apart in the discharge port 3121. In this embodiment, the number of the connecting members 3122 is two, and the two connecting members 3122 are distributed at 180°. The positioning post 33 is located at the central position of the discharge port 3121. One end of the connecting member 3122 is fixedly connected to the positioning post 33, and the other end is fixedly connected to the side wall of the discharge port 3121 to realize the installation of the positioning post 33. Of course, in other embodiments, other numbers of connecting members 3122 can also be provided, such as three, four, etc. Similarly, the installation form of the flow guiding member 32 is the same as that of the positioning post 33, which will not be elaborated here.

[0034] Specifically, the fabric sleeve 31 includes a sleeve 311 and a cover plate 312. An inlet port 3111 and a storage bin 3112 are formed in the sleeve 311. The inlet port 3111 is close to the top end of the sleeve 311, and the storage bin 3112 is close to the bottom end of the sleeve 311. The cover plate 312 is arranged at the bottom end of the sleeve 311, and the discharge port 3121 is formed through the cover plate 312. A through hole with the same diameter as the discharge port 3121 is provided at the bottom end of the sleeve 311, so that the discharge port 3121 is communicated with the storage bin 3112 through the through hole. Of course, in some embodiments, the through hole can also be cancelled, and the discharge port 3121 is directly communicated with the storage bin 3112. It can be understood that by providing the cover plate 312, during fabric placement, the cover plate 312 can be used to cover the top opening of the battery housing 5 to prevent the carbon particles from scattering out of the opening of the battery housing 5.

[0035] In one embodiment, a boss is formed on the side surface of the cover plate 312 facing away from the sleeve 311. The outer diameter of the boss is matched with the inner diameter of the battery housing 5, so that the boss can be inserted into the battery housing 5. Since a part of the cover plate 312 can be inserted into the battery housing 5, the connection stability between the entire fabric sleeve 31 and the battery housing 5 is improved, and displacement between the two is avoided.

[0036] In another embodiment, the cover plate 312 includes an inner plate 3123 and an outer plate 3124 which are coaxially arranged and are distributed on the same horizontal plane. The outer plate 3124 has an annular structure, and a receiving hole for receiving the inner plate 3123 is formed in the middle of the outer plate 3124. The inner plate 3123 is disposed in the receiving hole, that is, the inner plate 3123 is located on the inner ring side of the outer plate 3124. The inner plate 3123 and the outer plate 3124 are spaced apart from each other, so as to form a gap 3125 for inserting the battery case 5 between the inner plate 3123 and the outer plate 3124. Specifically, both the inner plate 3123 and the outer plate 3124 are independently connected and fixed to the sleeve 311. When fabricating, the fabricating mechanism descends, and the top end of the battery case 5 is inserted into the gap 3125 of the cover plate 312. At this time, the inner plate 3123 is inserted into the battery case 5. Since there is an insertion connection relationship between the battery case 5 and the cover plate 312, displacement between the two in the horizontal direction can be avoided, and the connection stability between the entire fabricating mechanism 3 and the battery case 5 can be improved.

[0037] Referring to Figure 1 and Figure 4 As shown, the pressing member 4 is a hollow long rod structure, and the cross-section of the pressing member 4 is in an annular shape. The pressing member 4 is vertically arranged, its top end is connected and fixed to the cross beam 13, and its bottom end is used for extruding the carbon particles in the battery case 5. One end of the pressing member 4 facing the workbench 2 (i.e., the bottom end) is provided with an avoidance hole 41 for passing through the positioning column 33 and the flow guiding member 32, and the length of the avoidance hole 41 extends along the axis direction of the pressing member 4. When pressing, the pressing member 4 descends, the flow guiding member 32 and the positioning column 33 are inserted into the avoidance hole 41, and the bottom end of the pressing member 4 extrudes the carbon particles. A cleaning groove 42 is arranged on the hole wall of the avoidance hole 41. The diameter of the cleaning groove 42 is B2, the diameter of the avoidance hole 41 is B1, and B2 > B1. The cleaning groove 42 is arranged close to the bottom end of the pressing member 4. It can be understood that when pressing, the carbon particles will enter between the positioning column 33 and the hole wall of the avoidance hole 41, and under the extrusion action, the carbon particles adhere to the hole wall of the avoidance hole 41. By providing the cleaning groove 42, the inner diameter of the pressing member 4 changes suddenly at the position of the cleaning groove 42, so that the carbon particles cannot adhere to the inner wall of the pressing member 4, thereby avoiding the carbon particles from adhering to the inside of the pressing member 4.

[0038] Specifically, scale lines 43 are arranged on the outer wall of the pressing member 4. By arranging the scale lines 43, it is convenient for the user to directly observe the insertion depth of the pressing member 4 in the battery case 5 outside, so as to verify whether there is an error between the theoretical insertion depth and the actual insertion depth.

[0039] Specifically, the blank holder 4 is provided with an avoidance notch 44 for passing through the connecting member 3122. The length of the avoidance notch 44 extends along the length direction of the blank holder 4, and the opening of the avoidance notch 44 is located at the bottom end of the blank holder 4. When the blank holder 4 is inserted into the diversion member 32 and the positioning post 33, the connecting member 3122 penetrates into the avoidance notch 44 and moves along the length direction of the avoidance notch 44. Correspondingly, the position of the avoidance notch 44 is set corresponding to the position of the connecting member 3122.

[0040] Specifically, the battery positive electrode forming device further includes a control host, and the first driving assembly 11, the second driving assembly 14, the vibrator and the motor are all electrically connected to the control host. The control host controls the first driving assembly 11, the second driving assembly 14, the vibrator and the motor to perform corresponding actions.

[0041] In this embodiment, the usage method of the battery positive electrode forming device is as follows:

[0042] Step S1: Place the battery case 5 on the turntable 22 and clamp the battery case 5 by using the clamping assembly 23;

[0043] Step S2: Drive the cloth feeding mechanism 3 to descend by using the second driving assembly 14 until the top end of the battery case 5 is inserted into the gap 3125 of the cover plate 312;

[0044] Step S3: Start cloth feeding. Add carbon particles from the feed inlet 3111, and the carbon particles pass through the feed inlet 3111, the storage bin 3112, the second blanking channel 34 and the first blanking channel and fall into the battery case 5 in sequence. At the same time, when cloth feeding, the turntable 22 rotates, so that each area in the circumferential direction of the battery case 5 can be evenly cloth fed;

[0045] Step S4: After cloth feeding is completed, the turntable 22 stops rotating. Turn on the vibrator to vibrate the battery case 5 so that the accumulation of carbon particles is tighter. Of course, in some embodiments, vibration can also be performed synchronously during the rotation of the turntable 22.

[0046] Step S5: Drive the blank holder 4 to descend by using the first driving assembly 11, and the blank holder 4 squeezes the carbon particles to make them compact.

[0047] Step S6: The blank holder 4 and the cloth feeding mechanism 3 rise and disengage from the battery case 5, and the production of the carbon positive electrode is completed. Before the cloth feeding mechanism 3 rises, the turntable 22 rotates 2 - 3 circles, so that the positioning post 33 and the carbon positive electrode rotate relative to each other, that is, it plays a role in shaping the carbon positive electrode, so that the side surface of the carbon positive electrode close to the positioning post 33 is well separated from the positioning post 33, and it is avoided that the side surface of the carbon positive electrode close to the positioning post 33 is scratched during the rising process of the positioning post 33.

[0048] Remarkable effects of this embodiment: By rotatably arranging the turntable 22 on the platform 21, when feeding the materials, the battery case 5 is driven to rotate by the turntable 22, so that the carbon particles falling into the battery case 5 are more evenly distributed in the circumferential direction of the battery case 5, avoiding the uneven stacking thickness of the carbon particles in the circumferential direction of the battery case 5 due to different resistances and flow rates when the carbon particles fall from the feeding mechanism 3. At the same time, after the carbon positive electrode is formed and before the positioning post 33 is separated from the carbon positive electrode, the turntable 22 can be rotated to make the positioning post 33 and the carbon positive electrode rotate relative to each other, which plays a role in shaping the carbon positive electrode and enables the side surface of the carbon positive electrode close to the positioning post 33 to be well separated from the positioning post 33, avoiding scratching the side surface of the carbon positive electrode close to the positioning post 33 during the rising process of the positioning post 33. This method is beneficial to improving the forming quality of the carbon positive electrode. Moreover, by arranging the vibrator, the battery case 5 is vibrated by the vibrator to eliminate the gaps between the carbon particles, make the stacking of the carbon particles more compact, shorten the working time of the pressing member 4, and improve the forming efficiency of the carbon positive electrode.

[0049] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes. The content of this specification should not be construed as a limitation to the present invention.
