Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0059] This application provides a gripper that can be used to hold pouch batteries or other objects that need to be kept upright. The following description uses a pouch battery as an example to illustrate the embodiments of this application.
[0060] Figure 1 This is a perspective view of a pouch cell provided according to an embodiment of this application. (Reference) Figure 1 The pouch battery 200 includes an air bag 201 and a main body 202. Along the height direction H of the pouch battery, the air bag 201 is positioned above the main body 202.
[0061] Figure 2 This is a perspective view of a gripper provided in one embodiment of this application. (Reference) Figure 2 The gripper 100 provided in the embodiments of this application includes a first gripping part 1, a second gripping part 2, a third gripping part 3 and a fourth gripping part 4.
[0062] The first clamping part 1 is used to clamp the air bag 201 of the soft-pack battery.
[0063] The second clamping part 2 is also an air bag 201 used to clamp the soft-pack battery. That is, the first clamping part 1 and the second clamping part 2 are used together to clamp the air bag 201 of the soft-pack battery.
[0064] The second clamping part 2 clamps the air bag 201 of the soft-pack battery 200 together by being close to the first clamping part 1.
[0065] For example, the second clamping part 2 moves closer to the first clamping part 1 by translation or rotation.
[0066] The third clamping part 3 and the fourth clamping part 4 are disposed below the first clamping part 1 along the height direction H of the grippers. The height direction H of the grippers is also the height direction H of the pouch battery 200.
[0067] It should be understood that since the first clamping part 1 and the second clamping part 2 are used to jointly clamp the air bag 201 of the soft-pack battery, the third clamping part 3 and the fourth clamping part 4 are also located below the second clamping part 2 along the height direction H.
[0068] The third clamping part 3 is used to clamp the main body 202 of the soft-pack battery.
[0069] The fourth clamping part 4 is also the main body 202 used to clamp the pouch battery. That is, the third clamping part 3 and the fourth clamping part 4 are used together to clamp the main body 202 of the pouch battery.
[0070] The fourth clamping part 4 clamps the main body 202 of the soft-pack battery 200 together by being close to the third clamping part 3.
[0071] For example, the fourth clamping part 4 moves closer to the third clamping part 3 by translation or rotation.
[0072] As can be seen from the above, the second clamping part 2 is close to the first clamping part 1 and together with the first clamping part 1 clamps the air bag 201 of the soft-pack battery 200; since the third clamping part 3 and the fourth clamping part 4 are arranged below the first clamping part 1 along the height direction H of the gripper 10, the fourth clamping part 4 is close to the third clamping part 3 and together with the third clamping part 3 clamps the main body 202 located below the air bag 201; since the gripper 10 can clamp the air bag 201 and the main body 202 of the soft-pack battery 200 in the height direction H, it can support the air bag 201 and the main body 202 of the soft-pack battery 200, so that the large-sized soft-pack battery can be kept upright and formed.
[0073] refer to Figure 2 The aforementioned gripper 10 may also include a first half-claw 5 and a second half-claw 6.
[0074] The second half-claw 6 is rotatably connected to the first half-claw 5; that is, the second half-claw 6 is connected to the first half-claw 5 and can rotate relative to the first half-claw 5.
[0075] The first clamping part 1 and the third clamping part 3 are disposed on the first half claw 5.
[0076] The second clamping part 2 and the fourth clamping part 4 are disposed on the second half claw 6.
[0077] The second half-claw 6 rotates relative to the first half-claw 5, causing the second clamping part 2 to move closer to the first clamping part 1, jointly clamping the air bag 201 of the soft-pack battery 200, and causing the fourth clamping part 4 to move closer to the third clamping part 3, jointly clamping the main body 202 of the soft-pack battery 200.
[0078] refer to Figure 2 The first half-claw 5 may be provided with a first recessed portion 51, and the second half-claw 6 may be provided with a second recessed portion 61.
[0079] The first recessed portion 51 abuts against the second recessed portion 61.
[0080] The abutting position of the first recess 51 and the second recess 61 is the rotational connection position of the first half claw 5 and the second half claw 6, so that the first clamping part 1 and the second clamping part 2 can at least partially abut, and the third clamping part 3 and the fourth clamping part 4 can at least partially abut, thereby realizing the clamping of the air bag 201 and the main body 202 of the soft pack battery 200.
[0081] refer to Figure 2 The first clamping part 1 and the second clamping part 2 can be directly opposite each other, thereby increasing the contact area between the first clamping part 1 and the second clamping part 2 and the air bag 201, and thus achieving a secure clamping of the air bag 201.
[0082] refer to Figure 2 The third clamping part 3 and the fourth clamping part 4 can be directly opposite each other, thereby increasing the contact area between the third clamping part 3 and the fourth clamping part 4 and the main body 202, and thus achieving a secure clamping of the main body 202.
[0083] refer to Figure 2 The first recess 51 is disposed below the third clamping part 3 along the height direction H, and the second recess 61 is disposed below the fourth clamping part 4 along the height direction H, so as to make room above the first half claw 5 and the second half claw 6 along the height direction H, so as to facilitate the arrangement of the first clamping part 1, the third clamping part 3, the second clamping part 2 and the fourth clamping part 4.
[0084] refer to Figure 2 The aforementioned gripper may also include a first connecting component 7 and a second connecting component 8.
[0085] The first connecting part 7 is rotatably connected to the end of the first half-claw 5 that is away from the first clamping part 1.
[0086] The second connecting member 8 is rotatably connected to the end of the second half-claw 6 that is away from the second clamping part 2.
[0087] The second connecting member 8 is rotatably connected to the first connecting member 7, such that when the first connecting member 7 rotates relative to the second connecting member 8, it can drive the first clamping part 1 to approach the second clamping part 2 and the third clamping part 3 to approach the fourth clamping part 4.
[0088] Figure 3 A perspective view of a fixture provided in an embodiment of this application. Figure 4 A front view of a fixture provided according to an embodiment of this application. (Reference) Figure 3 and Figure 4 Embodiments of this application also provide a clamp for holding a pouch battery. The clamp includes one or more grippers 10 as described in any of the above embodiments. Each gripper 10 is for a pouch battery.
[0089] The fixtures provided in the embodiments of this application can be used for loading and unloading soft-pack batteries, that is, as loading and unloading fixtures.
[0090] refer to Figure 3 The aforementioned fixture may also include a fixing component 30.
[0091] Each gripper 10 is disposed on the fixing member 30. For example, each gripper 10 is distributed on the fixing member 30.
[0092] The fixing component 30 can be a plate-like structure.
[0093] refer to Figure 3 The fixing component 30 is provided with multiple mounting holes 301. Each gripper 10 passes through each mounting hole 301, such that the first clamping part 1, the third clamping part 3, the second clamping part 2 and the fourth clamping part 4 are located above the fixing component 30 along the height direction H, while the first connecting part 7 and the second connecting part 8 are located below the fixing component 30. This allows the fixing component 30 to support the pouch battery when it slips out, preventing the slipping pouch battery from interfering with the normal operation of the device.
[0094] refer to Figure 3 The aforementioned grippers 10 can be arranged in columns and side by side, so that two side by side grippers 10 can hold the same pouch battery.
[0095] The first clamping part 1 and the second clamping part 2 of each gripper 10 are used to clamp the air bag 201 of the common soft-pack battery 200, and the third clamping part 3 and the fourth clamping part 4 of each gripper are used to clamp the main body 202.
[0096] refer to Figure 3 The aforementioned fixture may also include a guide component 40.
[0097] The guide component 40 is used to guide the pouch battery.
[0098] The number of guide components 40 can be one or more.
[0099] For example, each guide component 40 can be fixed to the fixed component 30.
[0100] refer to Figure 3 When there are multiple guide components 40, each guide component 40 is arranged along the arrangement direction L of the grippers 10, so that each pouch battery can be located between two adjacent guide components 40. In this way, two adjacent guide components 40 can guide the same pouch battery (such as guiding the pouch battery during loading and unloading) and separate adjacent pouch batteries, which can prevent damage to the pouch battery and protect the pouch battery.
[0101] refer to Figure 3 and Figure 4 The aforementioned fixture may be provided with a good product placement area 110 and a defective product placement area 120.
[0102] The good product placement area 110 is used to place soft-pack batteries that are good products.
[0103] The defective product placement area 120 is used to prevent soft-pack batteries that are defective from being stored.
[0104] There are multiple grippers 10. Some of the grippers 10 are located in the good product placement area 110 to hold good products; other grippers 10 are located in the defective product placement area 120 to hold defective products.
[0105] refer to Figure 3 The aforementioned fixture may also include a skew detection sensor 50.
[0106] The skew detection sensor 50 is located on one side of the gripper 10 to determine that the pouch battery is skewed based on the detection of an obstruction signal triggered by the side of the pouch battery 200.
[0107] The side of the pouch battery 200 can be a tab.
[0108] The number of tilt detection sensors 50 can be one or more.
[0109] The skew detection sensor 50 can be two opposing photoelectric sensors. Alternatively, the skew detection sensor 50 can be a diffuse reflection photoelectric sensor.
[0110] refer to Figure 3 Specifically, skew detection sensors 50 can be set on the left and right sides of the good product placement area 110. For example, a pair of skew detection sensors 50 can be set on the left side of the good product placement area 110 and a pair of skew detection sensors 50 can be set on the right side of the good product placement area 110.
[0111] Specifically, when the side of the pouch battery 200 (such as the tab) tilts to the left, it will block the tilt detection sensor 50 on the left, thus determining that the pouch battery 200 has tilted to the left; when the side of the pouch battery 200 tilts to the right, it will block the tilt detection sensor 50 on the right, thus determining that the pouch battery 200 has tilted to the right.
[0112] As can be seen from the above, skew detection sensors 50 are installed on the left and right sides of the good product placement area 110 to detect whether the side of the soft-pack battery 200 is skewed, thus achieving comprehensive detection.
[0113] refer to Figure 3 The aforementioned fixture may also include a slip detection sensor 60.
[0114] The slip detection sensor 60 is positioned below the tilt detection sensor 50 along the height direction H to determine that the pouch battery 200 has slipped based on an obstruction signal triggered by the bottom of the pouch battery 200.
[0115] The number of slip detection sensors 60 can be one or more.
[0116] The drop detection sensor 60 can be two opposing photoelectric sensors. Alternatively, the drop detection sensor 60 can be a diffuse reflection photoelectric sensor, in which case a single diffuse reflection photoelectric sensor can detect whether the pouch battery 200 has slipped.
[0117] refer to Figure 3 The slip detection sensor 60 is positioned below the tilt detection sensor 50 along the height direction H. If both the slip detection sensor 60 and the tilt detection sensor 50 detect an obstruction signal, it indicates that the slip of the pouch battery 200 is caused by tilting. Therefore, it can be determined that the pouch battery 200 is tilted or slips at an angle. If the slip detection sensor 60 detects an obstruction signal, but the tilt detection sensor 50 does not detect an obstruction signal, it indicates that the pouch battery 200 has slipped vertically. Therefore, it can be determined that the pouch battery 200 has slipped.
[0118] As can be seen from the above, the tilt detection sensor 50 and the slip detection sensor 60 can accurately detect whether the soft-pack battery is tilted or slipped, thus improving the detection accuracy.
[0119] refer to Figure 3 The aforementioned fixture may also include a leakage detection sensor 70.
[0120] The leakage detection sensor 70 is positioned above the slippage detection sensor 60 along the height direction H to determine if a pouch battery has been missed based on the continuous detection of an obstruction signal triggered by the pouch battery.
[0121] The number of leakage detection sensors 70 can be one or more. The leakage detection sensor 70 can also be a diffuse reflection photoelectric sensor, so that a single diffuse reflection photoelectric sensor can detect whether the pouch battery 200 has been removed.
[0122] The material leakage detection sensor 70 can be two opposing photoelectric sensors. Alternatively, the material leakage detection sensor 70 can be a diffuse reflection photoelectric sensor.
[0123] refer to Figure 3 If the pouch battery 200 slips, the leakage detection sensor 70 will not continuously detect the obstruction signal. At this time, the pouch battery 200 is still in the fixture, but the slippage detection sensor 60 will detect the obstruction signal when the pouch battery 200 slips. If the pouch battery 200 is not removed, the leakage detection sensor 70 will continuously detect the obstruction signal, while the slippage detection sensor 60 will not detect the obstruction signal. If the pouch battery 200 is removed normally, the leakage detection sensor 70 will not continuously detect the obstruction signal, and the slippage detection sensor 60 will not detect the obstruction signal. Therefore, the slippage detection sensor 60 and the leakage detection sensor 70 work together to accurately detect whether the pouch battery 200 is in the fixture.
[0124] refer to Figure 3 The aforementioned fixture may also include a scanning head 80.
[0125] refer to Figure 3 The scanning head 80 is positioned around the gripper 10 to scan the battery information code, thereby placing pouch batteries that meet the scanning criteria in the good product placement area 110 and placing pouch batteries that do not meet the scanning criteria in the defective product placement area 120.
[0126] The aforementioned information code can be a QR code or a number.
[0127] The scanning head 80 can be specifically set on the fixed component 30.
[0128] refer to Figure 3 The aforementioned fixture may also include a defective product full-material detection sensor 90.
[0129] A defective product full-load detection sensor 90 is located in the defective product placement area 120 to determine that the defective product placement area 120 is full based on the detection of an obstruction signal triggered by a pouch battery at a designated location in the defective product placement area 120. The designated location may be the position of the last gripper 10 in the defective product placement area 120.
[0130] The defective product full-material detection sensor 90 can be two opposing photoelectric sensors. Alternatively, the defective product full-material detection sensor 90 can be a diffuse reflection photoelectric sensor.
[0131] refer to Figure 3 The aforementioned fixture may also include a drive mechanism 130.
[0132] The drive mechanism 130 is connected to the gripper 10 to drive the gripper 10 to open and close.
[0133] The drive mechanism 130 can be a rotating mechanism, such as a cam mechanism.
[0134] The aforementioned drive mechanism 130 can also be a telescopic mechanism, such as a mechanism that uses a telescopic component as a power source.
[0135] The telescopic mechanism is connected to the connection between the first connecting part 7 and the second connecting part 8 to drive the gripper 10 to open and close through telescopic movement.
[0136] For example, when the telescopic mechanism extends, the gripper 10 closes to hold the pouch battery; when the telescopic mechanism retracts, the gripper 10 opens to release the pouch battery.
[0137] refer to Figure 3 The aforementioned drive mechanism 130 may specifically include a telescopic component 131 and a drive connection component 132.
[0138] The telescopic component 131 can be a pneumatic cylinder or a hydraulic cylinder.
[0139] The piston rod of the telescopic component 131 is connected to the drive connection component 132 to drive the drive connection component 132 to extend or retract.
[0140] The drive connection component 132 is connected to the connection between the first connection component 7 and the second connection component 8, so as to drive the gripper 10 to open and close through the telescopic movement.
[0141] refer to Figure 3 The aforementioned drive mechanism 130 may also include a telescopic component fixing member 133.
[0142] The telescopic component fastener 133 is connected to the telescopic component 131 and to the fixed component 30, thereby fixing the telescopic component 131 to the telescopic component fastener 133.
[0143] The number of telescopic components 131, drive connection components 132, and telescopic component fasteners 133 can be one or more.
[0144] Example, reference Figure 3Each pouch battery 200 is held by two parallel grippers 10, and each drive connection component 132 is connected to the two parallel grippers 10, so that each telescopic component 131 drives the two parallel grippers 10 to open and close through a drive connection component 132; each telescopic component 131 is fixedly connected to the fixed component 30 through a telescopic component fixing component 133; this enables independent control of the two parallel grippers 10; of course, if the telescopic component 131 is connected to only one gripper 10 through the drive connection component 132, then independent control of a single gripper 10 can be achieved.
[0145] As can be seen from the above, the opening and closing of the gripper 10 is facilitated by the telescopic mechanism, which simplifies the structure.
[0146] The working principle of the fixture provided in the embodiments of this application is as follows:
[0147] The fixtures provided in the embodiments of this application can be used for loading and unloading soft-pack batteries; see reference Figure 3 During loading, all grippers 10 of the fixture are fully opened by the telescopic component 131 (e.g., a cylinder). When the loading robot (not shown in the figure) loads the material, it first scans the information code of the soft-pack battery with the scanning head 80 to bind the information. If the scanning result is a defective product, the loading robot places the defective soft-pack battery in the defective product placement area 120. The number of grippers 10 in the defective product placement area 120 is limited. When the defective product placement area 120 is full of defective products, the defective product full detection sensor 90 triggers an alarm to remind manual intervention.
[0148] If the scan result is good, the loading robot will place the good pouch batteries from the first position in the good product placement area 110 into the fixture in sequence. During placement, the guide component 40 can guide the pouch batteries and separate adjacent pouch batteries. After the pouch batteries are in place, the telescopic component 131 drives the gripper 10 to clamp the air bag 201 and the body 202 of the pouch battery, constraining the pouch battery and preventing it from shaking. The loading robot rises and continues the subsequent actions, and so on, until the pouch batteries fill the entire fixture. During the placement process, the tilt detection sensor 50 and the slip detection sensor 60 on the left and right sides will detect the shape of the pouch batteries. If the batteries are tilted or slip due to not being clamped tightly, the sensors will trigger an alarm and remind manual handling.
[0149] The principle of unloading is the same as that of loading, but the action flow is reversed. Specifically, when the unloading robot (such as the overhead crane robot) picks up the whole set of materials, it will first clamp the air bag 201, and then all the telescopic parts 131 will drive all the grippers 10 to release the air bag. The unloading robot will lift up and take away the soft-pack battery of the entire fixture at the same time. If a soft-pack battery is missed, the leakage detection sensor 70 will trigger an alarm and remind manual handling.
[0150] Embodiments of this application also provide a battery production apparatus, which includes the fixture provided in any of the above embodiments.
[0151] The embodiments of this application enable the soft-pack battery to stand upright by clamping it, thereby achieving the loading and unloading function.
[0152] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
