Description

[Technical Field]

[0001] The present invention relates to the technical field of battery formation, and more particularly to a battery formation apparatus and method. [Background technology]

[0002] The manufacturing of batteries generally requires a filling process, a standing process, and a chemical formation process. Currently, batteries are generally chemically treated using a chemical formation device, i.e., the battery is charged, causing a chemical reaction between the electrode material and the electrolyte in the battery at the solid-liquid two-phase interface, thereby forming a passivation film covering the surface of the electrode material, which is called a "solid electrolyte interface film (SEI film)."

[0003]

[0003] Conventional chemical conversion equipment generally includes a chemical conversion body warehouse, and in actual use, batteries transported via a battery conveying line after static treatment are typically first manually placed into a chemical conversion capsule, which temporarily seals the batteries, thereby preventing the electrolyte in the batteries from absorbing water during battery transport and affecting battery quality. The chemical conversion capsules and the batteries within the capsules are then manually transported to a chemical conversion body warehouse, and then a stacker is used to transport the chemical conversion capsules and the batteries within them to the chemical conversion body warehouse, where the batteries within the capsules are chemically converted. The chemical conversion treatment is then performed on the batteries within the capsules. The chemical conversion equipment with this structure requires manual placement of the statically converted batteries transported via the battery conveying line into a chemical conversion capsule, then transporting the chemical conversion capsules and the batteries within the chemical conversion capsules to the chemical conversion body warehouse, and then removing the chemical conversion treated batteries from the chemical conversion capsules and placing them on the battery conveying line, resulting in a heavy workload, reduced chemical conversion efficiency, and increased labor costs.

[0031] The capsule conveying circulating belt 40 is used to transport the chemical capsules 503 and the batteries 501 therein to the first capsule switching conveying line 50 after the batteries 501 are placed in the lumen of the lower cavity 5031 of the chemical capsules 503 and the snap cups 5032 of the chemical capsules 503 are capped onto the upper portions of the lower cavities 5031. It is also used to transport the chemical capsules 503 and the batteries 501 therein to the lower portion of the snap cup attaching / detaching manipulator 30 after the batteries 501 therein are chemically treated by the chemically treated body warehouse 70. The capsule conveying circulating belt 40 is a conventional roller chain conveyor belt, and its structure will not be described again here. The capsule conveying circulating belt 40 is installed on top of a circulation frame. The capsule conveying circulating belt 40 extends in the left-right direction.

[0032] The first capsule switching conveying line 50 is used to convey the chemically converted capsules 503 and the batteries 501 therein to the first capsule conveying belt 60, which is used to convey the chemically converted capsules 503 and the batteries 501 therein to the chemically converted body warehouse 70. The second capsule conveying belt 80 is used to convey the chemically converted capsules 503 and the batteries 501 therein to the second capsule switching conveying line 90 after the batteries 501 therein have been chemically converted by the chemically converted body warehouse 70, which is used to convey the chemically converted capsules 503 and the batteries 501 therein to the second capsule switching conveying line 90, which is used to convey the chemically converted capsules 503 and the batteries 501 therein after the chemical conversion treatment to the capsule conveying circulating belt 40. The structures of the first capsule conveying belt 60 and the second capsule conveying belt 80 are the same as those of the capsule conveying circulating belt 40, and therefore the structures of the first capsule conveying belt 60 and the second capsule conveying belt 80 will not be described again here. The first capsule conveying belt 60 is installed on the top of the first conveying frame, and the second capsule conveying belt 80 is installed on the top of the second conveying frame. The first capsule switching conveying line 50 has a conventional structure and mainly includes a conveying line main body 51 extending along the front-rear direction and an intermediary belt 52 extending along the left-right direction, the intermediary belt 52 being installed on the top of the conveying line main body 51, and the intermediary belt 52 and the conveying line main body 51 being installed in a crisscross manner.The conveying line main body 51 mainly includes a belt frame 511, a belt track 512 installed on the top of the belt frame 511, and a belt motor installed at the bottom end of the relay belt 52. The longitudinal direction of the belt track 512 is the same as that of the belt frame 511. The relay belt 52 is slidably installed on the top of the belt frame 511 via a conventional slide rail slider assembly. A belt gear is fitted to the end of the output shaft of the belt motor, and the belt gear is meshed with the belt track 512. The belt motor is used to drive the belt gear to rotate. The meshing action between the belt gear and the belt track 512 allows the belt gear to move back and forth along the belt track 512, thereby moving the belt motor and the relay belt 52 back and forth relative to the belt frame 511. The structure of the relay belt 52 is the same as that of the capsule conveying circulating belt 40. The second capsule switching conveying line 90 and the first capsule switching conveying line 50 have the same structure and are installed symmetrically.

[0033] In actual application, the above structure first places the chemical capsule 503 on the capsule conveying circulating belt 40 and positions it below the snap cup attaching / detaching manipulator 30. The snap cup attaching / detaching manipulator 30 then operates to drive the snap cup attaching / detaching lifting cylinder 34 to move the two snap cup attaching / detaching grippers 37 downward to predetermined positions, respectively positioned in front of and behind the snap cup 5032 of the chemical capsule 503 on the capsule conveying circulating belt 40. The two snap cup attaching / detaching grippers 37 are then driven by the two snap cup attaching / detaching gripper cylinders 34 to move them toward each other, thereby clamping the snap cup 5032 of the chemical capsule 503. The snap cup attaching / detaching lifting cylinder 34 then drives the two snap cup attaching / detaching grippers 37 and the snap cup 5032 of the chemical capsule 503 upward to their initial positions. Then, the snap cup attachment / detachment motor 33 drives the snap cup attachment / detachment gear 331 to rotate, thereby moving the two snap cup attachment / detachment grippers 37 and the snap cup 5032 of the chemical capsule 503 backward, positioning the snap cup 5032 of the chemical capsule 503 behind the lower cavity 5031 of the chemical capsule 503, and thus removing the snap cup 5032 of the chemical capsule 503 from the top of the lower cavity 5031 of the chemical capsule 503.

[0034] After the battery 501 is transported below the battery placement manipulator 10 via the battery transport line 502, the longitudinal direction of the battery 501 is the same as the longitudinal direction of the chemical framework 1. As shown in FIG. 2 , the battery placement manipulator 10 operates by first rotating the two battery placement grippers 19 using the battery placement rotation cylinder 15, for example, by 90 degrees clockwise. The battery placement lift cylinder 14 then drives the two battery placement grippers 19 downward to predetermined positions, positioning the two battery placement grippers 19 in front of and behind the battery 501, respectively. The two battery placement gripper cylinders 18 then drive the two battery placement grippers 19 toward each other, thereby clamping the battery 501. The battery placement lift cylinder 14 then drives the two battery placement grippers 19 and the battery 501 upward to their initial positions. Then, the battery placement rotating cylinder 15 rotates the two battery placement grippers 19 and the battery 501, for example, by 90 degrees counterclockwise, so that the longitudinal direction of the battery 501 is the same as the width direction of the chemical framework 1, as shown in Figure 2. Then, the battery placement motor 13 rotates the battery placement gear 131, which moves the two battery placement grippers 19 and the battery 501 backward, and positions the battery 501 above the lower cavity 5031 of the chemical capsule 503. The battery placement lift cylinder 14 then drives the two battery placement grippers 19 and the battery 501 to move downward, placing the battery 501 into the lumen of the lower cavity 5031 of the chemical formation capsule 503, with part of the battery 501 protruding from the top of the lower cavity 5031 and the negative electrode of the battery 501 connecting with the negative electrode chemical formation probe 5039 in the lower cavity 5031 of the chemical formation capsule 503, thereby electrically connecting the negative electrode of the battery 501 to the negative electrode chemical formation probe 5039. The two battery placement gripper cylinders 18 then drive the two battery placement grippers 19 to move apart, thereby releasing the battery 501. The battery placement lift cylinder 14 then drives the two battery placement grippers 19 to move upward to their initial positions.Thereafter, the battery placement motor 13 drives the battery placement gear 131 to rotate, thereby moving the two battery placement grippers 19 forward to their initial positions.

[0035] Then, the snap cup attachment / detachment manipulator 30 operates, first driving the snap cup attachment / detachment gear 331 to rotate using the snap cup attachment / detachment motor 33, thereby moving the two snap cup attachment / detachment grippers 37 and the snap cup 5032 of the chemical capsule 503 forward, and positioning the snap cup 5032 of the chemical capsule 503 above the lower cavity 5031 of the chemical capsule 503. Then, the snap cup attaching / detaching lifting cylinder 34 drives the two snap cup attaching / detaching grippers 37 and the snap cup 5032 of the chemical formation capsule 503 to move downward, so that the snap cup 5032 of the chemical formation capsule 503 fits over the top of the lower cavity 5031 of the chemical formation capsule 503, a part of the battery 501 protruding from the top of the lower cavity 5031 is positioned within the first chamber of the snap cup 5032, the filling port of the battery 501 is fitted with the lower end of the airtightness measuring rod 5035 of the chemical formation capsule 503, and the positive electrode of the battery 501 is connected to the positive electrode formation probe 5037 of the chemical formation capsule 503, thereby electrically connecting the positive electrode of the battery 501 to the positive electrode formation probe 5037. Then, the two snap cup attaching / detaching gripper cylinders 36 drive the two snap cup attaching / detaching grippers 37 away from each other, thereby releasing the snap cup 5032 of the chemical formation capsule 503. Then, the snap cup attachment / detachment lifting cylinder 34 drives the two snap cup attachment / detachment grippers 37 to move upward to their initial positions, thus enabling the snap cup 5032 of the chemical capsule 503 to be fitted onto the top of the lower cavity 5031 of the chemical capsule 503.

[0036] Thereafter, the capsule conveying circulating belt 40 conveys the chemical capsules 503 and the batteries 501 inside the chemical capsules 503 in a direction approaching the first capsule switching conveying line 50. At the same time, the belt motor of the first capsule switching conveying line 50 drives the belt gear to rotate, thereby moving the relay belt 52 of the first capsule switching conveying line 50 in a direction approaching the capsule conveying circulating belt 40, and one end of the relay belt 52 is connected to one end of the capsule conveying circulating belt 40. In this way, the capsule conveying circulating belt 40 conveys the chemical capsules 503 and the batteries 501 inside the chemical capsules 503 to the relay belt 52 of the first capsule switching conveying line 50. Thereafter, the belt motor of the first capsule switching conveying line 50 drives the belt gear to rotate, thereby moving the relay belt 52 of the first capsule switching conveying line 50 in a direction approaching the first capsule conveying belt 60, and one end of the relay belt 52 of the first capsule switching conveying line 50 is connected to one end of the first capsule conveying belt 60. In this way, the relay belt 52 of the first capsule switching conveying line 50 can convey the chemical capsules 503 and the batteries 501 inside the chemical capsules 503 to the first capsule conveying belt 60. Thereafter, the first capsule conveying belt 60 conveys the chemical capsules 503 and the batteries 501 inside the chemical capsules 503 to the chemical product warehouse 70.

[0037] Then, the stacker 300 transports the chemical capsule 503 on the first capsule conveying belt 60 and the battery 501 inside the chemical capsule 503 into the placement cavity 721 and places them at the bottom of the placement groove 741, and connects the upper end of the lower current-carrying probe 762 to the corresponding negative electrode probe 50311 of the chemical capsule 503, and connects the upper end of the lower charging probe 75 to the negative electrode terminal 5038 of the chemical capsule 503, so that the upper end of the lower current-carrying probe 762 is electrically connected to the corresponding negative electrode probe 50311, and the upper end of the lower charging probe 75 is electrically connected to the negative electrode terminal 5038. Then, the second anodizing plate 772 is driven to move downward by the anodizing lifting cylinder 773, thereby moving the upper energizing probe 782, the upper charging probe 79, and the liquid storage cup 775 downward, until the lower end of the upper energizing probe 782 is connected to the corresponding positive electrode probe 5036 of the anodizing capsule 503, the lower end of the upper charging probe 79 is connected to the upper terminal 5034 of the anodizing capsule 503, and the bottom end of the liquid storage cup 775 is inserted into the upper end of the airtight measuring rod 5035 of the anodizing capsule 503. In this way, the power supply can achieve electrical connection with the heating plate of the anodizing capsule 503 through the lower energizing probe 762 and the negative electrode probe 50311, the upper energizing probe 782, and the positive electrode probe 5036, thereby energizing the heating plate. After being energized, the heating plate generates heat, thereby heating the battery 501 in the lumen of the lower cavity 5031 of the chemical formation capsule 503. At the same time, the charging power source is electrically connected to the negative electrode of the battery 501 via the lower charging probe 75, the negative electrode terminal 5038, and the negative electrode chemical formation probe 5039, and to the positive electrode of the battery 501 via the upper charging probe 79, the positive electrode terminal 5034, and the positive electrode chemical formation probe 5037. In this way, the charging power source charges the battery 501, causing a chemical reaction between the electrode material and the electrolyte at the solid-liquid two-phase interface in the battery 501, thereby forming a layer of passivation film covering the surface of the electrode material, and thus achieving chemical formation of the battery 501 at high temperatures.During the charging process of battery 501, a vacuum device is used to evacuate the interior of battery 501 via reservoir cup joint 7751, reservoir cup 775, and airtight measuring rod 5035 of chemical formation capsule 503, creating a negative pressure inside battery 501. In this way, gases due to chemical formation in battery 501 can be quickly discharged from battery 501. The charging time of battery 501 is, for example, 20 hours, the degree of vacuum inside battery 501 is, for example, -40 Kpa, and the temperature heated by the heating plate to battery 501 is, for example, 45°C. During the vacuuming process of battery 501, the electrolyte extracted from battery 501 can be stored in reservoir cup 775. When the interior of battery 501 returns to normal pressure, the electrolyte in reservoir cup 775 can return to battery 501 via airtight measuring rod 5035, thereby again irrigating the cells of battery 501.

[0038] After the chemical conversion is complete, the stacker 300 transports the chemically converted capsules 503 in the placement cavities 721 and the batteries 501 in the chemically converted capsules 503 to the second capsule conveying belt 80. At the same time, the belt gear of the second capsule switching conveying line 90 is driven to rotate by the belt battery, thereby moving the relay belt 52 of the second capsule switching conveying line 90 in a direction approaching the second capsule conveying belt 80, connecting one end of the relay belt 52 of the second capsule switching conveying line 90 to one end of the second capsule conveying belt 80. In this way, the second capsule conveying belt 80 can transport the chemically converted capsules 503 and the batteries 501 in the chemically converted capsules 503 to the relay belt 52 of the second capsule switching conveying line 90. Thereafter, the belt gear is driven to rotate by the belt battery of the second capsule switching conveying line 90, thereby moving the relay belt 52 of the second capsule switching conveying line 90 in a direction approaching the capsule conveying circulation belt 40, and one end of the relay belt 52 of the second capsule switching conveying line 90 is connected to one end of the capsule conveying circulation belt 40. In this way, the relay belt 52 of the second capsule switching conveying line 90 can convey the chemically treated chemical capsules 503 and the batteries 501 inside the chemically treated capsules 503 to the capsule conveying circulation belt 40. Thereafter, the capsule conveying circulation belt 40 conveys the chemically treated chemical capsules 503 and the batteries 501 inside the chemically treated capsules 503 below the snap cup attaching / detaching manipulator 30.

[0039] The snap cup attaching / detaching manipulator 30 then removes the snap cup 5032 of the chemical capsule 503 from the top of the lower cavity 5031 of the chemical capsule 503 in accordance with the steps described above. At the same time, the battery removal manipulator 20 operates, and the battery removal motor 23 drives the battery removal gear to rotate, thereby moving the two battery removal grippers 29 backward and positioning them above the battery 501. The battery removal lifting / lowering cylinder 24 then drives the two battery removal grippers 29 to move downward to predetermined positions, positioning the two battery removal grippers 29 to the left and right of the battery 501, respectively. The two battery removal gripper cylinders 28 then drive the two battery removal grippers 29 toward each other, thereby clamping the battery 501. The battery removal lift cylinder 34 then drives the two battery removal grippers 29 and the battery 501 to move upward to their initial positions. The battery removal motor 23 then drives the battery removal gear to rotate, thereby moving the two battery removal grippers 29 and the battery 501 forward to their initial positions. The battery removal rotation cylinder 25 then drives the two battery removal grippers 29 and the battery 501 to rotate them 90 degrees counterclockwise, for example. The battery removal lift cylinder 24 then drives the two battery removal grippers 29 and the battery 501 to move downward, continuing this process until the battery 501 is placed on the battery conveying line 202. The battery removal gripper cylinder 28 then drives the two battery removal grippers 29 to move away from each other, thereby releasing the battery 501. Thereafter, the battery removal lifting cylinder 24 is driven to move the two battery removal grippers 29 upward to their initial positions, thereby removing the post-chemical treatment battery 501 from the inner cavity of the lower cavity 5031 of the chemical capsule 503 and placing it on the battery conveying line 202.

[0040] Thereafter, the battery 501 is transported to the next process via the battery transport line 202, and at the same time, the next battery 50 transported from the battery transport line 202 is placed into the inner cavity of the lower cavity 5031 of the chemical capsule 503 by the battery placement manipulator 10 according to the steps described above, and then the steps described above are repeated.

[0041] The present invention can realize, by using the installed battery placement manipulator 10, snap cup attachment / detachment manipulator 30, and battery removal manipulator 20, automatically placing the battery 501 after static treatment, which is transported via the battery transport line 202, into the chemical formation capsule 503, and automatically removing the battery 501 after chemical formation treatment from the chemical formation capsule 503 and placing it on the battery transport line 202. The installed capsule transport circulation belt 40, first capsule switching transport line 50, and first capsule transport belt 60 can automatically remove the battery 501 after static treatment from the chemical formation capsule 503 and place it on the battery transport line 202. The batteries 501 in the chemical capsules 503 are transported to the chemical conversion body warehouse 70, which then performs chemical conversion on the batteries 501 in the chemical conversion capsules 503.
