Description

Technical Field

[0001] The invention relates to the technical field of battery capacity division and formation equipment, and in particular to an automatic hot pressing battery charging and discharging device. Background Art

[0002] In the battery manufacturing process, capacity formation is an important process to ensure battery performance and quality. Capacity formation usually uses automatic charging and discharging equipment to charge or discharge the battery to test the battery's capacity, stability and reliability. In this process, the battery needs to be clamped by a fixture to ensure that the battery maintains a stable physical state during the charging and discharging process. At the same time, the fixture must also provide appropriate pressure and heat for the battery so that the battery can be charged and discharged under predetermined pressure and temperature conditions, thereby optimizing the battery's chemical reaction and performance.

[0003] However, the current capacity-dividing formation process faces challenges brought by the diversification of battery shell structures. Battery cells on the market are mainly divided into two types: metal hard shell and soft shell. Due to the differences in structure and material between the two types of battery shells, existing charging and discharging equipment requires different types of fixtures and material trays during the clamping and heating process. For example, metal hard shell batteries usually require stronger fixtures to provide sufficient pressure, while soft shell batteries require softer and more flexible fixtures to avoid damaging the battery shell. In addition, different types of battery cells also require different material trays during loading and handling to accommodate differences in their shapes and sizes.

[0004] This practice of designing special fixtures and trays for different battery shells has led to the diversification and complexity of the configuration of charging and discharging equipment. Specifically, it is necessary to equip each type of battery cell with a separate fixture and tray, which increases the overall cost of the equipment. In addition, since each device occupies a certain amount of physical space, the configuration of multiple devices will also cause the production line to occupy too much space, affecting production efficiency and factory space utilization.

[0030] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0031] This embodiment discloses an automatic hot-pressing battery charging and discharging device for use in the capacity division and formation process during the battery manufacturing process. Figure 1 and Figure 2 The charging and discharging device includes a packaging box 1, an opening and closing mechanism 2, a hot pressing mechanism 3 and a conveying mechanism 4.

[0032] For box 1, if Figure 3 , which is used to package a battery core BT, the packaging box 1 includes a box body 10 and a box cover 11, and the packaging box 1 is provided with notches 12 corresponding to the electrodes of the battery core BT.

[0033] When charging and discharging the battery cell BT, the box cover 11 of the packaging box 1 needs to be opened first, and then the battery cell BT is placed in the box body 10, and then the box cover 11 is closed on the box body 10. Finally, the packaging box 1 filled with the battery cell BT is used as a carrier to perform charging and discharging operations under pressure and heating.

[0034] As for the opening and closing mechanism 2, it is used to open or close the packaging box 1. In this regard, the packaging box 1 includes a support platform 20 for supporting the packaging box 1, a gripper 21 and a first driver 22 connected to the gripper 21, the gripper 21 is used to grab or release the box cover 11, and the first driver 22 is used to drive the gripper 21 to approach or move away from the support platform 20 to open or close the box cover 11.

[0035] like Fig. 9 and Fig.10 The hot pressing mechanism 3 is an actuator for performing charge and discharge operations on the packaging box 1 filled with battery cells BT, and includes a first pressing plate 31 , a second pressing plate 32 and an electrode connector 33 .

[0036] The first pressing plate 31 and the second pressing plate 32 are disposed opposite to each other and can move relatively to each other so as to clamp the package box 1 filled with the battery cells BT between the first pressing plate 31 and the second pressing plate 32 .

[0037] The electrode connector 33 is used to connect the battery cell BT in the packaging box 1 between the first pressing plate 31 and the second pressing plate 32 to a charging and discharging power source. At least one of the first pressing plate 31 and the second pressing plate 32 has a heating element 34 to provide a target temperature environment for the charging and discharging operation of the battery cell BT.

[0038] like Figure 1 and Figure 6 , the transport mechanism 4 is used to transport the packaging box 1 and the battery cell BT to different workstations. Specifically, the packaging box 1 and the battery cell BT are transported to the opening and closing mechanism 2 in sequence. After the battery cell BT is loaded into the packaging box 1 through the opening and closing mechanism 2, the packaging box 1 loaded with the battery cell BT is transported to the hot pressing mechanism 3. In addition, after the charging and discharging is completed, the packaging box 1 loaded with the battery cell BT is transported from the hot pressing mechanism 3 to the opening and closing mechanism 2. At this time, when the box cover 11 is opened by the opening and closing mechanism 2, the battery cell BT and the packaging box 1 are transported to their respective material placement locations in sequence.

[0039] like Figure 4 and Figure 5 The first driver 22 includes a first rotating motor 220 and a support plate 221 connected to the rotating shaft of the first rotating motor 220. When the first rotating motor 220 rotates, the support plate 221 is driven to rotate up and down.

[0040] The gripper 21 includes a flip plate 21, the bottom of the flip plate 21 is pivotally connected to the support platform 20, and the top of the flip plate 21 is connected to the free end of the support plate 221. The support plate 221 can drive the top of the flip plate 21 to rotate relative to the bottom so that the flip plate 21 is close to or away from the support platform 20. A plurality of first suction holes 210 based on the action of negative pressure airflow are arranged on one side of the flip plate 21 close to the support platform 20.

[0041] In addition, the support platform 20 has an inclined surface 23 that abuts against the box body 10 of the packaging box 1, and the inclined surface 23 has a plurality of second suction holes 200 based on the negative pressure airflow.

[0042] When loading the battery cell BT, first rotate the first rotating motor 220 to drive the flip plate 21 to flip in the direction away from the support platform 20 through the support plate 221. Then, place the packaging box 1 on the support platform 20. At this time, draw negative pressure on the second suction hole 200 to adsorb the box body 10 of the packaging box 1 on the support platform 20. Next, reverse the first rotating motor 220 to drive the flip plate 21 to flip in the direction close to the support platform 20, and draw negative pressure on the first suction hole 210. When the flip plate 21 abuts against the box cover 11, the box cover 11 is adsorbed through the first suction hole 210. Then, reverse the first rotating motor 220 again to drive the flip plate 21 to flip in the direction away from the support platform 20, thereby separating the box cover 11 from the box body 10, as shown in FIG. Figure 5 , and the battery cell BT is loaded into the box body 10. Then, the first rotary motor 220 is reversed again, driving the flip plate 21 to flip toward the support platform 20, and the box cover 11 is closed on the box body 10. Then, the negative pressure in the first suction hole 210 is released, and the first rotary motor 220 is reversed again, driving the flip plate 21 to flip toward the support platform 20. At this time, the support platform 20 is placed with a packing box 1 containing a battery cell BT.

[0043] The process of taking out the battery cell BT from the packaging box 1 is similar to the above process and will not be described again.

[0044] In addition, if Figure 2 A visual monitoring device 24 is also provided on one side of the opening and closing mechanism 2 to monitor the operation of the opening and closing mechanism 2.

[0045] On the other hand, Figure 1 , Figure 2 , Figure 7 and Figure 8 The charging and discharging device in this embodiment further includes a first tray 5 and a second tray 6. The first tray 5 is provided with a plurality of pairs of first slots 50, and the first slots 50 are used to fix the packaging box 1.

[0046] The second tray 6 is provided with a plurality of pairs of second slots 60 for fixing the battery cells BT. The opening and closing mechanism 2 is located between the first tray 5 and the second tray 6 .

[0047] On the other hand, Fig. 9 and Fig.10 The hot pressing mechanism 3 also includes a first mounting bracket 35 and a second driver 36 arranged on the first mounting bracket 35. The first pressing plate 31 is arranged at one end of the first mounting bracket 35 and is fixedly connected to the first mounting bracket 35. The second pressing plate 32 is connected to the second driver 36 through a guide rod 37. The second driver 36 is used to drive the second pressing plate 32 to approach or move away from the first pressing plate 31 through the guide rod 37, so that the second pressing plate 32 reciprocates along the extension direction of the guide rod 37.

[0048] Specifically, a sliding sleeve 38 is provided at the edge of the first pressing plate 31 , and the guide rod 37 passes through the sliding sleeve 38 and is connected to the second driver 36 .

[0049] On the other hand, the second driver 36 includes a screw rod 360 and a second rotating motor 361 transmission-connected to the screw rod 360. The first mounting bracket 35 is also provided with a slide rail and a sliding frame 39 slidingly connected to the slide rail. The sliding frame 39 is also connected to the movable nut on the screw rod 360, and the guide rod 37 is connected to the sliding frame 39.

[0050] In this embodiment, when the second rotating motor 361 rotates, it drives the movable nut on the screw rod 360 to move linearly along the screw rod 360, thereby driving the sliding frame 39 to move along the slide rail, and then driving the guide rod 37 to move linearly through the sliding frame 39.

[0051] On the other hand, a second mounting bracket 70 connected thereto is disposed on the top of the first pressing plate 31 , and a third mounting bracket 71 slidably connected thereto and a third driver 72 for driving the third mounting bracket 71 to move horizontally are also disposed on the second mounting bracket 70 .

[0052] A probe rack 73 is also provided above the first pressing plate 31, and the probe rack 73 is connected to the third mounting bracket 71 via a lifting driver 74. A first conductive probe 33 serving as an electrode connector 33 is provided on the probe rack 73. The first conductive probe 33 is used to abut against an electrode in the notch 12 at the top of the packaging box 1.

[0053] It should be noted that a second conductive probe 33 ′ serving as an electrode connector 33 is also disposed at the side edge of the first pressing plate 31 .

[0054] When the battery cell BT is a hard shell, the notch 12 on the packaging box 1 is located at the top, so the battery cell BT is connected to the charging and discharging power source through the first conductive probe 33. Then, when the packaging box 1 filled with the battery cell BT is squeezed between the first pressing plate 31 and the second pressing plate 32, the third mounting bracket 71 is driven to move horizontally by the third driver 72, so that the first conductive probe 33 on the probe rack 73 is opposite to the electrode on the packaging box 1, and then, the lifting driver 74 is started to drive the probe rack 73 to move downward, so that the first conductive probe 33 is in contact with the electrode on the packaging box 1.

[0055] When the battery cell BT is a soft shell, the notch 12 on the packaging box 1 is located at the side, so the battery cell BT is connected to the charging and discharging power source through the second conductive probe 33'. When the packaging box 1 filled with the battery cell BT is squeezed between the first pressing plate 31 and the second pressing plate 32, the second conductive probe 33' abuts against the electrode located at the side of the packaging box 1.

[0056] On the other hand, Fig.11 , Fig.13 A limiting column 80 is provided at the edge of the first pressing plate 31, and an enlarged portion 81 is provided at the top of the limiting column 80. The diameter of the enlarged portion 81 is larger than the diameter of the limiting column 80. Figure 3 A limiting hole 13 is provided on the side of the packaging box 1. The limiting hole 13 is gourd-shaped and includes a first portion 130 and a second portion 131 that are connected to each other. The diameter of the first portion 130 is equal to that of the bulging portion 81, and the diameter of the second portion 131 is equal to that of the limiting column 80. The first portion 130 is located below the second portion 131.

[0057] In this regard, when the packaging box 1 is placed between the first pressure plate 31 and the second pressure plate 32, the first part 130 of the upper limit hole 13 of the packaging box 1 is aligned with the enlarged part 81 of the limiting column 80, so that the enlarged part 81 enters the limiting hole 13, and then the grip of the packaging box 1 is released. The packaging box 1 moves downward under the action of its own gravity, so that the second part 131 with a smaller diameter abuts against the limiting column 80. At this time, due to the obstruction of the enlarged part 81, the packaging box 1 is prevented from falling off the limiting column 80.

[0058] On the other hand, Fig.11 The first pressing plate 31 includes a first substrate 310 , a first heat insulating plate 311 and a first heating plate 312 . The first heat insulating plate 311 is located between the first substrate 310 and the first heating plate 312 .

[0059] like Fig.12 The second pressing plate 32 includes a second substrate 320 , a second heat insulating plate 321 and a second heating plate 322 . The second heat insulating plate 321 is located between the second substrate 320 and the second heating plate 322 .

[0060] The first heating plate 312 and the second heating plate 322 are both provided with heating elements 24 .

[0061] The front and rear sides of the packaging box 1 are respectively in contact with the first heating plate 312 and the second heating plate 322 .

[0062] Two ends of the guide rod 37 are connected to the first base plate 310 and the second base plate 320 respectively, wherein the sliding sleeve 38 is located on the first base plate 310 .

[0063] In addition, a pressure sensor (not shown) is disposed on the back of the second substrate 320 to detect the pressure between the first substrate 310 and the second substrate 320 .

[0064] On the other hand, Figure 1 and Figure 6 The transport mechanism 4 includes a frame and a first manipulator 40 and a second manipulator 41 disposed on the frame and movable in three axes. The first manipulator 40 is used to transport the packaging box 1 and the battery cell BT to or from the opening and closing mechanism 2. The second manipulator 41 is used to transport the packaging box 1 filled with the battery cell BT between the hot pressing mechanism 3 and the opening and closing mechanism 2. In this embodiment, the working efficiency of the charging and discharging device is effectively improved through the cooperation of the two manipulators.

[0065] Specifically, the first robot 40 and the second robot 41 both grasp the packaging box 1 or the battery cell BT by negative pressure adsorption.

[0066] In summary, when the automatic hot pressing battery charging and discharging device disclosed in the above embodiment performs the charging and discharging work of the battery cell BT. First, the first manipulator 40 grabs an empty packaging box 1 from the first tray 5 and places it on the support table 20 of the opening and closing mechanism 2. Then, the first rotating motor 220 operates to open the packaging box 1. Next, the first manipulator 40 grabs a battery cell BT from the second tray 6 and places the battery cell BT in the box body 10 of the opened packaging box 1 on the support table 20. Then, the first rotating motor 220 operates again to close the packaging box 1. Next, the first manipulator 40 resets and accurately grabs another empty packaging box 1, and the second manipulator 41 moves to the support table 20 position, grabs and transfers the packaging box 1 filled with battery cells BT (hereinafter referred to as the battery box) to the hot pressing mechanism 3, and places it on the first pressing plate 31. Then, the second rotating motor 361 rotates to drive the second pressing plate 32 to move toward the first pressing plate 31 to press the battery box. When the battery cell BT completes the charging and / or discharging work in the pressurizing mechanism, the second rotating motor 361 rotates again to separate the second pressing plate 32 from the first pressing plate 31. Then, the second manipulator 41 moves the battery box on the first pressing plate 31 to the support table 20 at the station where the opening and closing mechanism 2 is located, and the first rotating electrode rotates to open the packaging box 1 of the battery box, and the battery cell BT is taken out and placed in the second tray 6 by the first manipulator 40, and the packaging box 1 is put back into the first tray 5. In this cycle, all battery cells BT are automatically charged and discharged.

[0067] The above-mentioned automatic hot-pressing battery charging and discharging device is equipped with an openable and closable packaging box 1 for the battery cell BT. In this way, when charging and discharging different types of battery cells BT are performed in the battery capacity formation process, it is only necessary to configure the corresponding packaging box 1 according to the type of battery cell BT, and there is no need to purchase fixtures and material trays separately for each battery type, thereby significantly reducing equipment procurement and maintenance costs; in addition, it also reduces the need for parallel configuration of multiple equipment, optimizes the production line layout, effectively saves the factory's space resources, and improves space utilization.

[0068] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
