Based on the position data, the controller uses the robotic arm to control the pressure rod to move to the battery clamp and drives the locking member to move, thereby releasing the position lock of the clamp body and switching the clamp body to the open position.

[0007] In one embodiment, the robotic arm includes a base and a robotic arm. The base is disposed on the bracket, the robotic arm is rotatably disposed on the base, and a mounting plate is disposed at the end of the robotic arm away from the bracket. The pressure rod and the camera are both disposed on the mounting plate.

[0008] In one embodiment, a distance sensor is provided on the mounting plate to detect the position of the clamp body and thus confirm whether the clamp body is in the open position.

[0009] In one embodiment, the battery clamp further includes a base, the clamp body is rotatably mounted on the base via a first pivot, the locking member is movably mounted on the base, the first pivot has a locking block corresponding to the position of the locking member, and the locking block has a slot; the locking member is inserted into the slot to lock the position of the clamp body.

[0010] The controller can control the pressure rod through the robot arm according to the position data, drive the locking member to move, so that the locking member disengages from the slot and releases the position lock of the clamp body.

[0011] In one embodiment, the clamp body includes a base plate, a pressure block, and a counterweight. The base plate is connected to the first rotating shaft. The pressure block is disposed on the side of the base plate facing the placement area and abuts against the top surface of the battery pack. The counterweight is disposed on the side of the base plate away from the placement area. The counterweight can drive the base plate to rotate when the position lock of the clamp body is released, so that the clamp body switches from the fixed position to the open position.

[0012] In one embodiment, the locking element includes a hollow rod, a locking pin, and a pressure plate. The hollow rod is disposed on the base, a first end of the locking pin passes through the hollow rod, and a second end of the locking pin is inserted into the slot. The pressure plate is disposed at the end of the hollow rod away from the slot and is rotatably connected to the first end of the locking pin via a second rotating shaft. The end of the hollow rod away from the slot has a strip-shaped hole extending along its axial direction, and the second rotating shaft is slidably disposed in the strip-shaped hole.

[0013] The controller can control the pressure rod through the robot arm according to the position data, drive the pressure plate to rotate, and then drive the locking pin to move so that the second end of the locking pin disengages from the slot and releases the position lock of the fixture body.

[0017] In one embodiment, the clamp opening device further includes a scanner disposed on one side of the work area, the scanner being used to detect whether there is a worker in the work area; the robotic arm has a low-speed operation mode and a high-speed operation mode;

[0018] When the scanner detects a worker in the working area of ​​the robotic arm, the controller acquires the detection signal from the scanner and switches the robotic arm to the low-speed operating state; when the scanner detects no worker in the working area of ​​the robotic arm, the controller acquires the detection signal from the scanner and switches the robotic arm to the high-speed operating state.

[0019] In addition, this utility model also proposes a vehicle production equipment, including the clamp opening device as described above.

[0020] This invention utilizes a robotic arm, a camera, a pressure rod, and a controller.

The battery clamp includes a clamp body and a locking mechanism. The clamp body is used to fix and release the battery pack, while the locking mechanism locks the clamp body in a fixed position, ensuring the battery pack is stably fixed to the conveyor trolley. Simultaneously, the locking mechanism can release the clamp body's position lock, allowing it to switch to the open position and release the battery pack, which can then be removed from the conveyor trolley.

The camera acquires the locking mechanism's position data, and the navigation and positioning system sends a position signal to the controller when the conveyor trolley reaches the work area. Specifically, when the conveyor trolley moves to the work area, the navigation and positioning system sends a positioning signal to the controller. When the controller receives the positioning signal, it acquires the position data of the locking mechanism from the camera and, based on this data, controls the lever via a robotic arm to move to the battery clamp. The robotic arm drives the lever, which in turn moves the locking mechanism, releasing the clamp body from its fixed position to the open position; thus, the battery clamp can be opened. This clamp opening device, by incorporating a robotic arm, camera, lever, and controller, replaces manual labor in opening battery clamps, improving work efficiency and reducing worker workload. This clamp opening device is applied in the field of vehicle manufacturing technology. Attached Figure Description

[0033] As a core component for energy storage and supply in vehicles, the battery pack provides power for vehicle operation, supports electronic devices, and also functions as an energy recovery unit, provides stable power supply, stores and communicates information, and offers safety protection. In actual production, researchers have found that battery packs are mostly transported using conveyor trolleys and secured with battery clamps. When installing the battery pack onto the vehicle, the clamps must first be opened to release the battery pack. Currently, the clamps are typically opened manually. However, since battery packs are often secured by multiple clamps simultaneously, workers must walk around the conveyor trolley to open the clamps, which not only affects work efficiency but also increases the labor intensity for workers.

[0034] This utility model proposes a clamp opening device and vehicle production equipment, aiming to solve the technical problems of low operation efficiency and high labor intensity when opening battery clamps.

[0035] Please see Figures 1 to 4 In one embodiment of this utility model, the clamp opening device includes a conveyor trolley 100, a battery clamp 200, a support 300, a robotic arm 400, and a controller. A working area 310 is provided below the support 300, and the conveyor trolley 100 can pass through the working area 310. The conveyor trolley 100 is provided with a placement area 110 for placing the battery pack. The battery clamp 200 is disposed on one side of the placement area 110. The battery clamp 200 includes a clamp body 210 and a locking member 220. The clamp body 210 has a fixed position for fixing the battery pack and an open position for releasing the battery pack. The locking member... The 220 mechanism can lock the position of the clamp body 210 to keep it in a fixed position, and can also release the position lock of the clamp body 210 to switch it to the open position. The robot arm 400 is equipped with a camera 410 and a pressure bar 420. The camera 410 is used to acquire the position data of the locking element 220. The conveyor trolley 100 is equipped with a navigation and positioning system, which is used to send a position signal to the controller when the conveyor trolley 100 runs to the work area 310. The camera 410, robot arm 400, and navigation and positioning system are all connected to the controller. When the controller receives the position signal, the controller acquires the position data. Based on the position data, the controller controls the pressure bar 420 to run to the battery clamp 200 through the robot arm 400, and drives the locking element 220 to move, releasing the position lock of the clamp body 210 so that the clamp body 210 switches to the open position.

[0036] The technical solution of this utility model, by setting up a robotic arm 400, a camera 410, a pressure rod 420, and a controller, uses the controller to control the operation of the pressure rod 420 and drive the movement of the locking member 220 to release the position lock of the clamp body 210, allowing the clamp body 210 to switch to the open position. Compared with manually opening the battery clamp 200, this can improve work efficiency and reduce the labor intensity of workers. In this embodiment, the conveyor trolley 100 is used to place and transport the battery pack. The battery clamp 200 includes a clamp body 210 and a locking member 220. The clamp body 210 is used to fix and release the battery pack, while the locking member 220 can lock the position of the clamp body 210, so that the clamp body 210 is always in a fixed position, ensuring that the battery pack is stably fixed on the conveyor trolley 100. At the same time, the locking member 220 can also release the position lock of the clamp body 210, allowing the clamp body 210 to switch to the open position, thereby releasing the battery pack and allowing the battery pack to be removed from the conveyor trolley 100. The robotic arm 400 can drive the locking member 220 to move via the pressure rod 420, thereby releasing the position lock of the clamp body 210 and switching the clamp body 210 to the open position, thus opening the battery clamp 200. The camera 410 is used to acquire the position data of the locking member 220, and the navigation and positioning system is used to send a position signal to the controller when the conveyor trolley 100 runs to the work area 310. Specifically, when the conveyor trolley 100 runs to the work area 310, the navigation and positioning system sends a position signal to the controller; when the controller receives the position signal, the controller can acquire the position data of the locking member 220 acquired by the camera 410, and according to the above position data, control the pressure rod 420 via the robotic arm 400 to move to the battery clamp 200, and the robotic arm 400 drives the pressure rod 420 to move, thereby driving the locking member 220 to move, releasing the position lock of the clamp body 210, and switching the clamp body 210 from the fixed position to the open position; thus, the battery clamp 200 can be opened. This clamp opening device, equipped with a robotic arm 400, a camera 410, a pressure rod 420, and a controller, allows the machine to open the battery clamp 200, replacing manual labor. This improves work efficiency and reduces the workload of workers. This clamp opening device is applied in the field of vehicle manufacturing technology.

[0037] It should be noted that the "open position for releasing the battery pack" mentioned above means that when the clamp body 210 is in the open position, the battery pack is not fixed by the clamp body 210. In other words, when the clamp body 210 is in the open position, the battery pack can be removed from the conveyor trolley 100 and transferred to the vehicle to be produced. In this embodiment, the conveyor trolley 100 can be an AGV trolley, which is an unmanned automated guided vehicle. It is guided by QR code coordinates and optical methods, travels along a predetermined route, has obstacle avoidance capabilities, and high safety protection. Its significant feature is that it is unmanned, equipped with an automatic guidance system, and can automatically travel along a predetermined route without manual guidance. The controller can be an industrial control computer.

[0038] Please see Figure 1 In one embodiment of this utility model, the robotic arm 400 includes a base 430 and a robotic arm 440. The base 430 is disposed on a support 300, and the robotic arm 440 is rotatably disposed on the base 430. A mounting plate 441 is disposed at the end of the robotic arm 440 facing away from the support 300. A pressure rod 420 and a camera 410 are both disposed on the mounting plate 441. In this embodiment, the robotic arm 400 has multiple degrees of freedom, enabling it to drive the pressure rod 420 to move in multiple directions, thereby driving the locking member 220 to move and releasing the position lock of the clamp body 210, allowing the clamp body 210 to switch to the open position. In a specific embodiment, the robotic arm 440 is composed of multiple connecting units, and in this embodiment of the utility model, the robotic arm 400 can be a collaborative robot with 6 degrees of freedom.

[0039] Please see Figure 2 In one embodiment of this utility model, a distance sensor 442 is provided on the mounting plate 441. The distance sensor 442 is used to detect the position of the clamp body 210, thereby confirming whether the clamp body 210 is in the open position. In this embodiment, the distance sensor 442 is used to detect the position of the clamp body 210 to confirm whether the clamp body 210 is fully opened. Specifically, in actual production, the side of the clamp body 210 away from the counterweight 213 can be set as the detection surface. After the pressure rod 420 drives the locking member 220 to move to open the clamp body 210, the distance sensor 442 is used to detect the position of the clamp body 210 to confirm whether the clamp body 210 is fully opened. In addition, the top surface of the battery pack or the plane of the conveyor trolley 100 used to place the battery pack can also be set as the detection surface. When the pressure rod 420 drives the locking member 220 to move to open the clamp body 210, the distance sensor 442 is used to detect the distance between it and the detection surface in real time. When the distance is within a preset range, it indicates that the clamp body 210 has been fully opened.

[0040] Please see Figure 3and Figure 4 In one embodiment of this utility model, the battery clamp 200 further includes a base 230. The clamp body 210 is rotatably mounted on the base 230 via a first rotating shaft 240. The locking member 220 is movably mounted on the base 230. The first rotating shaft 240 is provided with a locking block 241 corresponding to the position of the locking member 220. The locking block 241 is provided with a slot 242. The locking member 220 is inserted into the slot 242 to lock the position of the clamp body 210. The controller can control the pressure rod 420 through the robot arm 400 according to the position data to drive the locking member 220 to move, so that the locking member 220 disengages from the slot 242 and releases the position lock of the clamp body 210. In this embodiment, the clamp body 210 is rotatably mounted on the base 230 via the first rotating shaft 240. The locking member 220 can be inserted into the slot 242 of the locking block 241 mounted on the first rotating shaft 240 to lock the position of the clamp body 210, so that the clamp body 210 is always in a fixed position, ensuring that the battery pack is stably fixed on the conveyor trolley 100. When the conveyor trolley 100 runs to the working area 310, the controller will acquire the position data of the camera 410 and control the pressure rod 420 through the robot arm 400 according to the position data, drive the locking member 220 to move, so that the locking member 220 disengages from the slot 242, releases the position lock of the clamp body 210, and opens the battery clamp 200.

[0041] In one embodiment of this utility model, the clamp body 210 includes a base plate 211, a pressure block 212, and a counterweight 213. The base plate 211 is connected to a first rotating shaft 240. The pressure block 212 is disposed on the side of the base plate 211 facing the placement area 110 and abuts against the top surface of the battery pack. The counterweight 213 is disposed on the side of the base plate 211 away from the placement area 110. The counterweight 213 can drive the base plate 211 to rotate when the position lock of the clamp body 210 is released, so that the clamp body 210 switches from a fixed position to an open position. When the clamp body 210 is in a fixed position, the pressure block 212 abuts against the top surface of the battery pack to fix the position of the battery pack. After the position lock of the clamp body 210 is released, the clamp body 210 will rotate due to the gravity of the counterweight 213, so that the pressure block 212 separates from the top surface of the battery pack and switches the clamp body 210 from a fixed position to an open position, opening the battery clamp 200.

[0042] Please see Figure 3 and Figure 4In one embodiment of this utility model, the locking member 220 includes a hollow rod 221, a locking pin 222, and a pressure plate 223. The hollow rod 221 is disposed on the base 230. The first end of the locking pin 222 passes through the hollow rod 221, and the second end of the locking pin 222 is inserted into the slot 242. The pressure plate 223 is disposed at the end of the hollow rod 221 away from the slot 242, and is rotatably connected to the first end of the locking pin 222 through a second rotating shaft. The end of the hollow rod 221 away from the slot 242 is provided with a strip-shaped hole extending along its axial direction, and the second rotating shaft is slidably disposed in the strip-shaped hole. The controller can control the pressure rod 420 through the robot arm 400 according to the position data, drive the pressure plate 223 to rotate, and then drive the locking pin 222 to move, so that the second end of the locking pin 222 disengages from the slot 242 and releases the position lock of the clamp body 210. In this embodiment, the second end of the locking pin 222 can be inserted into the slot 242 to lock the position of the clamp body 210, so that the clamp body 210 is always in a fixed position. When the controller controls the pressure rod 420 to drive the pressure plate 223 to rotate through the robot arm 400, the pressure plate 223 will pull the locking pin 222 away from the slot 242 along the axis of the hollow rod 221, thereby causing the second end of the locking pin 222 to disengage from the slot 242, releasing the position lock of the clamp body 210. Subsequently, the counterweight 213 will drive the clamp body 210 to rotate under its own weight, so that the clamp body 210 switches from the fixed position to the open position, opening the battery clamp 200.

[0043] Please see Figure 2 and Figure 4 In one embodiment of this utility model, the pressure plate 223 is provided with a through hole 224, and the end of the pressure rod 420 is provided with a tapered block 421, the tip of which can pass through the through hole 224. When the pressure rod 420 drives the pressure plate 223 to rotate, the cooperation between the tapered block 421 and the through hole 224 can reduce the risk of slippage between the pressure rod 420 and the pressure plate 223, thereby ensuring the normal opening of the battery clamp 200.

[0044] Please see Figure 1 In one embodiment of this utility model, there are four battery clamps 200, arranged in a rectangular shape, and the four battery clamps 200 are arranged in pairs on both sides of the placement area 110. The controller can control the pressure rod 420 to move sequentially to each battery clamp 200 according to the position data via the robot arm 400, and drive the corresponding locking member 220 to move, thereby releasing the position lock of each clamp body 210 in sequence, so that each clamp body 210 switches to the open position. In this embodiment, using four battery clamps 200 to fix the battery pack can make the battery pack more stably fixed on the conveyor trolley 100; and the controller can sequentially open each battery clamp 200 to completely release the battery pack, ensuring that the battery pack can be transferred to the vehicle to be produced during subsequent transfer.

[0045] Please see Figure 1 In one embodiment of this utility model, the clamp opening device further includes a scanner 500 disposed on one side of the work area 310. The scanner 500 is used to detect whether there is a worker in the work area 310; the robotic arm 400 has a low-speed operation state and a high-speed operation state. In this embodiment, the scanner 500 is used to detect whether there is a worker in the work area 310, and the controller can obtain the detection signal of the scanner 500 and switch the operation state of the robotic arm 400 in a timely manner to ensure the safety of the worker and realize human-machine coexistence. Specifically, when the scanner 500 detects that there is a worker in the work area of ​​the robotic arm 400, the controller obtains the detection signal of the scanner 500 and switches the robotic arm 400 to a low-speed operation state to reduce the operation speed of the robotic arm 400 and thus better protect the worker; when the scanner 500 detects that there is no worker in the work area of ​​the robotic arm 400, the controller obtains the detection signal of the scanner 500 and switches the robotic arm 400 to a high-speed operation state to increase the operation speed of the robotic arm 400 and improve work efficiency.
