[0002] In automated production fields such as laser processing and precision assembly, clamping devices are often used to position and fix workpieces. Existing clamping devices mostly employ rigid connection structures, with the clamping components directly mounted to the frame via slide rails or other mechanisms. However, due to factors such as machining errors, assembly gaps, and long-term wear, the vertical height deviation of the two slide rails can easily cause misalignment in the relative vertical position of the two clamping components connected to the slide rails, leading to jamming and sticking during the clamping process.

[0042] Please see Figure 1 The clamping device provided in the embodiments of this application will now be described. The clamping device provided in the embodiments of this application includes:

[0043] Rack 1;

[0044] The first floating connection mechanism 2 and the second floating connection mechanism 3 are installed on the frame 1 at relative intervals in the horizontal direction;

[0045] The first clamping member 4 is slidably mounted on the frame 1 in the horizontal direction via the first floating connection mechanism 2. The first floating connection mechanism 2 is used to adjust the height of the first clamping member 4 in the vertical direction.

[0046] The second clamping member 5 is slidably mounted on the frame 1 in the horizontal direction via the second floating connection mechanism 3. The second floating connection mechanism 3 is used to adjust the height of the second clamping member 5 in the vertical direction.

[0047] The clamping drive unit 6 is mounted on the frame 1 and is connected to the first clamping unit 4 and the second clamping unit 5 for transmission. It is used to drive the first clamping unit 4 and the second clamping unit 5 to move closer or further apart in the horizontal direction in order to clamp or release the workpiece.

[0048] In this application embodiment, the workpiece can specifically be a battery module. In some embodiments, the workpiece can also be a battery cell.

[0049] The frame 1 serves as the supporting foundation for the entire device and can be constructed using aluminum alloy profiles or welded steel plates. Its upper surface is provided with an mounting plane for mounting various functional components. The first floating connection mechanism 2 and the second floating connection mechanism 3 are installed on the frame 1 at intervals along the horizontal direction, forming a workpiece clamping space between them.

[0050] The clamping drive unit 6 is mounted on the frame 1 and can be a linear drive element such as a cylinder, electric cylinder, or lead screw motor. The clamping drive unit 6 is connected to the first clamping member 4 and the second clamping member 5, and can simultaneously or separately drive the two clamping members to move closer or further apart in the horizontal direction to clamp or release the workpiece. In this embodiment, the clamping drive unit 6 is a double-rod cylinder, whose two piston rods are respectively connected to the first clamping member 4 and the second clamping member 5 to achieve synchronous centering clamping.

[0051] During operation, the clamping drive 6 drives the first clamping member 4 and the second clamping member 5 to move closer to each other. If there is a vertical assembly position deviation between the first clamping member 4 and the second clamping member 5, the first floating connection mechanism 2 and the second floating connection mechanism 3 can adaptively float and adjust in the vertical direction to eliminate the vertical position deviation between the first clamping member 4 and the second clamping member 5, eliminate jamming and sticking, and achieve a smooth and reliable clamping action.

[0052] The clamping device provided by this utility model, by setting a first floating connection mechanism and a second floating connection mechanism between the first clamping member 4, the second clamping member 5 and the frame 1, realizes the adaptive adjustment of the first clamping member 4 and the second clamping member 5 in the vertical direction, and has the following advantages compared with the prior art:

[0053] Eliminating the impact of assembly errors. The first floating connection mechanism 2 and the second floating connection mechanism 3 allow the first clamping part 4 and the second clamping part 5 to produce slight displacement in the vertical direction, which can compensate for the positional deviation of the first clamping part 4 and the second clamping part 5 in the vertical direction caused by machining errors and assembly gaps. This reduces the requirements for the machining accuracy of parts and facilitates assembly and debugging.

[0054] To prevent clamping and jamming. When there is a deviation in the relative position of the first clamping member 4 and the second clamping member 5 in the vertical direction, the first floating connection mechanism 2 and the second floating connection mechanism 3 can adaptively adjust the position of the first clamping member 4 and the second clamping member 5 in the vertical direction to avoid the jamming and sticking caused by rigid connection.

[0055] In this embodiment of the application, the first floating connection mechanism 2 includes a first guide component 21 and a first floating component 22. The first guide component 21 is floatingly connected to the frame 1 through the first floating component 22, and the first clamping member 4 is slidably installed on the first guide component 21.

[0056] The first floating component 22 is used to allow the first guide component 21 to float relative to the frame 1 in the vertical direction to adjust the height of the first clamping member 4 in the vertical direction.

[0057] During operation, the first clamping member 4 slides along the first guide assembly 21. When there is a positional deviation of the first guide assembly 21 relative to the frame 1 in the vertical direction, the movement of the first clamping member 4 becomes stuck. The first floating assembly 22 allows the first guide assembly 21 to float relative to it in the vertical direction, thereby adjusting the height of the first clamping member 4 in the vertical direction and achieving a smooth clamping action.

[0058] The second floating connection mechanism 3 is symmetrically arranged with the first floating connection mechanism 2, and includes a second guide component and a second floating component. Its structure and working principle are the same as those of the first floating connection mechanism 2, and will not be described in detail here.

[0059] In this embodiment of the application, the first floating component 22 includes a first connector 221 and a first floating component 222. The first connector 221 is floatingly connected to the frame 1 and the first guide component 21 respectively through the first floating component 222.

[0060] The first floating member 222 includes a first connecting secondary part and a first anti-detachment secondary part. The first connecting secondary part is movably inserted through the first connecting member 221 to connect with the frame 1 or the first guide assembly 21. The first anti-detachment secondary part is connected to the end of the first connecting secondary part to prevent the first connecting secondary part from detaching from the first connecting member 221.

[0061] The first connector 221 specifically includes a first horizontal section, a second horizontal section, and a vertical section. The first and second horizontal sections are respectively disposed at both ends of the vertical section to form an I-shaped connector. This I-shaped structure has high structural rigidity and stability, can effectively transmit clamping force, and maintains a lightweight design.

[0062] The first horizontal section is connected to the frame 1 through a number of first floating parts 222, and the second horizontal section is connected to the first guide assembly 21 through a number of first floating parts 222.

[0063] The first connecting secondary of the first floating member 222 can be connected to the frame 1 or the first guide assembly 21 via a threaded connection. The outer diameter of the first anti-detachment secondary can be larger than the mounting hole on the first connector for the first connecting secondary to pass through, to prevent the first connecting secondary from detaching from the first connector. Specifically, the first floating member 222 is a height-equalizing screw. The screw shank passes through the mounting hole of the first or second horizontal section and connects with the corresponding threaded hole on the frame 1 or the first guide assembly 21. The nut of the height-equalizing screw abuts against the first or second horizontal section, and there is a radial clearance between the screw shank and the mounting hole, thus forming a floating connection. This radial clearance allows the first connector 221 and the first guide assembly 21 to produce slight displacement in the vertical direction, achieving adaptive floating adjustment.

[0064] The first floating member 222 allows the first connecting member 221 and the first guide assembly 21 to float relative to each other in the vertical direction, so as to adaptively adjust the height of the first clamping member 4 in the vertical direction. When there is a vertical positional deviation of the first guide assembly 21 relative to the frame 1, the radial clearance between the equalizing screw and the mounting hole provides a floating margin, so that the first connecting member 221 drives the first guide assembly 21 to float in the vertical direction, thereby causing the first clamping member 4 to adaptively adjust the height in the vertical direction.

[0065] Several first floating members 222 can be arranged in a rectangular shape on the first and second horizontal sections to ensure the stability and load-bearing capacity of the floating connection.

[0066] The second floating connection mechanism 3 is symmetrically arranged with the first floating connection mechanism 2. The second floating component of the second floating connection mechanism 3 includes a second connector and a second floating component. The second connector is also an I-shaped structure, and the second floating component is also an equal-height screw. Its structure and working principle are the same as those of the first floating connection mechanism 2, and will not be described in detail here.

[0067] During operation, the clamping drive 6 drives the first clamping member 4 and the second clamping member 5 to move closer together to clamp the workpiece. If there is a positional deviation in the vertical direction of the first guide assembly 21 or the second guide assembly, the corresponding first floating member 222 or the second floating member uses radial clearance to allow the first connecting member 221 and the first guide assembly 21, the second connecting member and the second guide assembly to float relative to each other in the vertical direction, adaptively adjusting the position of the first clamping member 4 and the second clamping member 5 in the vertical direction, eliminating the jamming phenomenon caused by the vertical positional deviation, and achieving stable clamping.

[0068] In this embodiment of the application, the first guide component 21 includes a first slide groove 211 and a first slider 212. The first slide groove 211 is connected to the first connector 221 through a first floating member 222. The first slider 212 is slidably disposed in the first slide groove 211 and is connected to the first clamping member 4.

[0069] The first slide 211 can be made of metal profiles or machined parts and has a straight-lined guide channel. The first slide 211 is connected to the first connecting member 221 through the first floating member 222, so that the first slide 211 can float vertically together with the first connecting member 221. The arrangement direction of the first slide 211 is parallel to the horizontal direction, providing a straight guide for the first clamping member 4.

[0070] The first slider 212 is connected to the first clamping member 4, transmitting sliding guidance to the first clamping member 4. The first slider 212 and the first clamping member 4 can be fixed by bolt connection, welding, or integral molding to ensure connection rigidity.

[0071] The first floating member 222 allows the first connecting member 221 and the first guide assembly 21 to float relative to each other in the vertical direction, so as to adaptively adjust the position of the first clamping member 4 in the vertical direction. When there is a positional deviation of the first slide 211 relative to the frame 1 in the vertical direction, the first floating member 222 generates an adaptive displacement in the vertical direction, causing the first connecting member 221 to drive the first slide 211 and the first slider 212 to float in the vertical direction, thereby causing the first clamping member 4 to adaptively adjust its height in the vertical direction.

[0072] The second floating connection mechanism 3 is symmetrically arranged with the first floating connection mechanism 2, and includes a second guide component and a second floating component. The second guide component also includes a second slide and a second slider. Its structure and working principle are the same as those of the first floating connection mechanism 2, and will not be described in detail here.

[0073] In this embodiment of the application, the first clamping member 4 includes a first clamping part 41 and a first connecting part 42. The first connecting part 42 is connected to the first floating connecting mechanism 2, and the first clamping part 41 is adjustablely mounted on the first connecting part 42 in the horizontal direction.

[0074] The first connecting part 42 serves as an intermediate connecting component, fixedly connected to the first slider 212 in the first floating connecting mechanism 2, and receives adaptive position adjustment from the first floating connecting mechanism 2. The first connecting part 42 can be made of sheet metal or machined parts, and has appropriate structural strength and rigidity.

[0075] The first clamping part 41 is horizontally adjustable and mounted on the first connecting part 42 for direct contact and clamping of the workpiece. In this embodiment, the first clamping part 41 is bolted to the first connecting part 42 through an oblong hole. The position can be adjusted horizontally after the bolt is loosened, and it can be fixed after tightening.

[0076] In one embodiment, the first clamping part 41 can be slidably connected to the first connecting part 42 via a slide rail, and its position can be fixed in conjunction with a positioning pin or a set screw.

[0077] The first clamping part 41 is horizontally adjustable and mounted on the first connecting part 42. The clamping position can be pre-adjusted according to different specifications of workpieces, which expands the applicability of the device and improves its versatility.

[0078] In this embodiment, the second clamping member 5 may adopt the same structure as the first clamping member 4, which will not be described in detail here.

[0079] In this embodiment of the application, the first connecting part 42 is provided with a first limiting secondary part 421, which is used to stop the first clamping part 41 on the side away from the workpiece in the horizontal direction, so as to limit the position of the first clamping part 41 in the horizontal direction.

[0080] The first limiting secondary part 421 can be separately fixed to the first connecting part 42. In this embodiment, the first limiting secondary part 421 is an adjusting screw, and the limiting position is adjusted by the screwing depth to achieve fine adjustment.

[0081] The first limiting secondary part 421 abuts against the first clamping part 41 on the side away from the workpiece in the horizontal direction, forming a one-way limiting relationship, which can serve as the mounting reference for the first clamping part 41 on the first connecting part 42. When installing the first clamping part 41, by abutting its side away from the workpiece in the horizontal direction against the first limiting secondary part 421, the reference position of the first clamping part 41 in the horizontal direction can be quickly determined without additional measurement or alignment, simplifying the installation and positioning operation.

[0082] In this embodiment, a first insulating secondary part 411 is provided on the side of the first clamping part 41 that contacts the workpiece.

[0083] The first insulating secondary part 411 can be made of various conventional insulating materials. In one embodiment, the first insulating secondary part 411 is an insulating coating, such as a ceramic coating, an alumina coating, or an organic insulating varnish layer, which is attached to the clamping surface of the first clamping part 41 by spraying, dipping, or electroplating processes to form a thin-layer insulating structure. In another embodiment, the first insulating secondary part 411 is an insulating gasket, such as a rubber gasket, a silicone gasket, a nylon gasket, or an epoxy resin gasket, which is installed on the clamping surface of the first clamping part 41 by adhesive bonding or mechanical fixing to form a replaceable insulating structure. In yet another embodiment, the first insulating secondary part 411 is an insulating sleeve, such as a heat-shrink tubing or an injection-molded insulating sleeve, which covers the clamping end of the first clamping part 41 to form overall insulating protection.

[0084] The first insulating secondary part 411 is disposed on the side of the first clamping part 41 that contacts the workpiece, effectively blocking the electrical conduction path between the clamping device and the workpiece, preventing current from forming a circuit through the clamping device, and protecting the workpiece surface from electrolytic corrosion or arc damage.

[0085] In this embodiment of the application, the first clamping part 41 is further provided with a first detection secondary part 412 for detecting whether there is a workpiece.

[0086] The first detection secondary unit 412 can be implemented using various conventional sensing methods. In one embodiment, the first detection secondary unit 412 is a contact sensor, such as a micro switch or limit switch, disposed on the clamping surface of the first clamping part 41 that contacts the workpiece. When the workpiece is clamped in place, it contacts the sensor contact, triggering a detection signal. In another embodiment, the first detection secondary unit 412 is a non-contact sensor, such as a photoelectric sensor, an inductive proximity switch, or a capacitive proximity switch, embedded in the clamping surface or side of the first clamping part 41, identifying the presence or absence of a workpiece by detecting its presence or distance changes. In yet another embodiment, the first detection secondary unit 412 is a pressure sensor, disposed on the clamping force transmission path of the first clamping part 41, determining whether the workpiece is reliably clamped by detecting changes in the clamping force.

[0087] The first detection sub-unit 412 is set on the first clamping unit 41, which can automatically detect whether the workpiece is present and whether the clamping is in place, without the need for manual confirmation, thereby improving the degree of automation and production efficiency.

[0088] In this embodiment of the application, the frame 1 is provided with a detection element 11 for detecting whether the first clamping member 4 and the second clamping member 5 are in a clamping or releasing state.

[0089] The detection element 11 can be implemented using various conventional sensing methods. In one embodiment, the detection element 11 is a position sensor, such as a magnetic switch, Hall effect sensor, or photoelectric sensor, positioned on the frame 1 at a location corresponding to the movement path of the first clamping member 4 or the second clamping member 5. The position of the first clamping member 4 or the second clamping member 5 is detected to determine whether it is in a clamping or released state. In another embodiment, the detection element 11 is a limit switch, positioned on the frame 1 at the extreme or intermediate position of the movement of the first clamping member 4 or the second clamping member 5. A status signal is triggered when the clamping member touches the switch contact. In yet another embodiment, the detection element 11 is an encoder or displacement sensor, connected to the clamping drive 6. The real-time position of the first clamping member 4 or the second clamping member 5 is calculated by detecting the displacement to determine its working state.

[0090] During operation, the clamping drive 6 drives the first clamping member 4 and the second clamping member 5 to move closer or further apart. When the clamping member moves to the clamping position or the release position, it triggers the detection element 11 on the frame 1, which feeds back a status signal to the control system. The control system determines whether the clamping device is currently in a clamping or release state based on the detection signal, and controls the start and stop of subsequent processes accordingly.

[0091] The detection component 11 is set on the frame 1 and can automatically detect whether the first clamping component 4 and the second clamping component 5 are in a clamping or releasing state without the need for manual observation and confirmation, thereby improving the degree of automation and operational safety.

[0092] Please see Figure 2 , Figure 3 This application also provides a battery module transportation device, including a moving device and a clamping device as described in any of the above embodiments. The clamping device is used to clamp the battery module, and the moving device is connected to the clamping device in a transmission connection to drive the clamping device to transport the battery module.

[0093] The mobile device includes a mobile frame 7, a translation drive assembly 8, and several rotation drive assemblies 9. Several clamping devices are arranged sequentially and at intervals along the horizontal direction on the mobile frame 7. Each clamping device is rotatably mounted on the mobile frame 7 via a rotation drive assembly 9. The rotation drive assembly 9 is used to drive the corresponding clamping device to rotate relative to the mobile frame 7. The translation drive assembly 8 is connected to the mobile frame 7 and is used to drive the mobile frame 7 to move along the horizontal or vertical direction so as to drive the clamping devices to transport the battery module.

[0094] Specifically, the movable frame 7 is a long, horizontally extending frame structure that provides an installation reference and support for the clamping devices. Several clamping devices are arranged at equal or unequal intervals along the length of the movable frame 7, with appropriate spacing between adjacent clamping devices to avoid motion interference and meet the process space requirements of each workstation. Each clamping device is independently equipped with a rotary drive component 9, which can be a rotary cylinder, stepper motor, servo motor, or harmonic reducer, etc., and is fixedly installed at the corresponding position on the movable frame 7. Its output end is connected to the frame 1 of the clamping device for transmission, driving the clamping device to rotate relative to the movable frame 7 around the vertical or horizontal axis, thereby adjusting the posture of the clamping device to adapt to the angle requirements for picking up and placing battery modules from wire harnesses at different workstations.

[0095] In some embodiments, the translation drive assembly 8 may employ a linear motor, a servo motor in conjunction with a lead screw and nut mechanism, a synchronous belt drive mechanism, or a gear and rack mechanism, etc. The translation drive assembly 8 drives the moving frame 7 to move horizontally (e.g., along the production line direction) to switch the clamping device between different horizontal workstations; or drives the moving frame 7 to rise and fall vertically to switch the clamping device between different height workstations; it can also be combined to achieve compound motion in a two-dimensional plane, enabling the clamping device to accurately move back and forth between multiple spatially distributed workstations.

[0096] In this embodiment, the translation drive component 8 employs a three-axis motion drive, comprising three mutually perpendicular linear motion modules: an X-axis, a Y-axis, and a Z-axis. The X-axis module can be mounted on a frame such as a gantry and arranged along the production line direction. The Y-axis module is mounted on the guide rail of the X-axis module via a slider, and the Z-axis module is mounted on the guide rail of the Y-axis module via a slider. The moving frame 7 is fixed to the lifting end of the Z-axis module. The servo motors of the three axes are linked in coordination under the control system, driving the moving frame 7 to move the clamping device precisely in three-dimensional space. This allows for simultaneous coverage of multiple workstations in the horizontal plane and workstations at different heights, enabling automatic switching between multiple workstations in complex spatial layouts.

[0097] The battery module transport device of this application includes the clamping device in any of the above embodiments, and therefore has the beneficial effects brought by the clamping device in any of the above embodiments, which will not be repeated here.

[0098] 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.
