[0024] The following is combined with Figures 1 to 4 The utility model is further described in detail with specific embodiments, but is not intended to limit the utility model.
[0025] Example 1
[0026] A controllable gripping assembly, see Figures 1 to 3 , including a connecting part 1, a movable component 2 and a longitudinal movable part 3, the two connecting parts 1 are arranged opposite to each other, and a first sensor 11 is arranged on the side of one or each connecting part 1, the movable component 2 includes a first movable part 21 and a second movable part 22 which are slidably connected, the first movable part 21 is arranged on the connecting part 1 along the longitudinal direction T, each connecting part 1 is provided with the first movable part 21, and the second movable part 22 is connected to the longitudinal movable part 3, wherein the two longitudinal movable parts 3 are arranged opposite to each other, and a sensing element 31 corresponding to the first sensor 11 is arranged on one side of one or each longitudinal movable part 3.
[0027] The two connecting parts 1 are respectively connected to the driving ends 40 of the opening and closing driving member, and the opening and closing driving member can be a clamping claw cylinder, which can drive and control the opening and closing of the two connecting parts 1. Figure 4 , the opening and closing driving component is arranged on the supporting part 5, the upper surface of the supporting part 5 is connected to the moving part 6, the moving part 6 is arranged on the frame 7, and the moving part 6 can be embedded in the slide rail of the frame 7. Among them, the frame 7 has a supporting effect on the moving part 6, the supporting part 5, the clamping claw cylinder, etc. In the process of taking out the battery cell, the moving part 6 can slide along the surface of the frame 7 to drive the supporting part 5 and the clamping claw cylinder and other components to move to the corresponding positions, and the moving part 6 can be driven by other drivers arranged in the frame 7. In addition, the required linear cylinder can also be installed in the moving part 6, so that the output end of the linear cylinder is connected to the supporting part 5, and the linear cylinder can control the supporting part 5 to move up and down, so as to realize the connection part 1, the movable component 2 and the longitudinal movable part 3 to clamp the battery cell downward and take out the battery cell upward.
[0028] Preferably, the first sensor 11 and the driving end 40 of the opening and closing driving member are both electrically connected to a control unit. The control unit may be a PLC controller, and the PLC controller may be installed on the frame 7 .
[0029] Preferably, at least a portion of the connecting portion 1 is an L-shaped structure, and at least a portion of the longitudinal movable portion 3 is a flat plate-shaped structure, a paddle-shaped structure or a palm-shaped structure.
[0030] In some implementations, more than two connection parts 1 may be arranged opposite to each other, and each connection part 1 may be respectively connected to a driving end 40 of an opening and closing driving member, and each connection part 1 may be connected to one or more longitudinal movable parts 3 via a movable member 2 .
[0031] Preferably, the connecting portion 1 is provided with at least two first movable portions 21, a first limiting portion 23 is provided on one side of at least one first movable portion 21, a second limiting portion 32 for abutting against the first limiting portion 23 is provided on one side of the longitudinal movable portion 3, the first limiting portion 23 and the second limiting portion 32 are provided correspondingly, the second limiting portion 32 is located between the first sensor 11 and the first limiting portion 23, and the first limiting portion 23 is used to prevent the longitudinal movable portion 3 from sliding out of the first movable portion 21. Specifically, the first limiting portion 23 is a T-shaped limiting block.
[0032] In the clamping assembly, the clamping claw cylinder, the connecting part 1, the first movable part 21, and the first sensor 11 constitute the upper half of the entire clamping assembly; the sensor 31, the T-shaped limit block, the second movable part 22 and the longitudinal movable part 3 constitute the lower half of the entire clamping assembly; the first movable part 21 is a slide rail, and the second movable part 22 is a slider, and the upper and lower parts are connected to the slider through the slide rail.
[0033] After the 3C battery cell is formed, it is often necessary to place it in a tray. During the process of the clamping assembly clamping the battery cell and moving vertically downward, if the position of the battery cell is offset and the angular position of the battery cell is pressed to the position of the clamping strip, the two longitudinal movable parts 3 of the lower half of the clamping assembly clamp the battery cell. This will cause the battery cell and the longitudinal movable part 3 to be subject to resistance from the clamping strip, and the lower half of the entire clamping assembly will undergo relative displacement, and the lower half may slide relatively. The longitudinal movable part 3 is driven by the upward thrust to drive the sensing part 31 to gradually approach the first sensor 11, that is, during the relative sliding process, the distance between the sensing part 31 and the first sensor 11 decreases, and the first sensor 1 may be a proximity sensor, and the proximity sensor may use an eddy current proximity switch, a capacitive proximity switch, a Hall switch, a photoelectric proximity switch, etc. according to the actual application scenario. When the sensing element 31 reaches the sensing range of the first sensor 11, the sensor signal changes, and the first sensor 11 can transmit the signal to the PLC controller arranged in the clamping assembly. The PLC controller makes a command to stop the downward movement of the clamping assembly according to the signal, thereby stopping the downward pressure in time, thereby effectively preventing the corner of the battery cell from continuing to be subjected to force and being crushed.
[0034] Preferably, the distance between the first sensor 11 and the sensing element 31 is smaller than the length of the first movable portion 21 along the longitudinal direction T to ensure that the first sensor 11 can quickly and effectively detect the sensing element 31, and the length of the first movable portion 21 along the longitudinal direction T is 0.2 to 0.4 times the length of the second movable portion 22 along the longitudinal direction T.
[0035] Preferably, the first sensor 11 is an eddy current proximity switch, and the sensing element 31 is a conductor. The eddy current proximity switch is sometimes also called an inductive proximity switch. When a conductive object approaches the proximity switch that can generate an electromagnetic field, eddy currents are generated inside the object. The eddy currents react to the proximity switch, causing the internal circuit parameters of the switch to change, thereby generating the required detection signal.
[0036] By dividing the clamping assembly into two sections, the clamping assembly is subjected to resistance during its movement, so that the longitudinal movable portion 3 therein can undergo relative displacement. The first sensor 11, which serves as a proximity sensor, detects the displacement of the longitudinal movable portion 3 driving the sensing member 31 to obtain the sensing signal and transmit the sensing signal. When the lower half of the device slides relatively, the sensor can detect the required signal and transmit the signal to the PLC controller, thereby controlling the timely stop of the clamping assembly.
[0037] Example 2
[0038] Different from the first embodiment, the first sensor 11 is a capacitive proximity switch, and the sensing element 31 is a conductor, a semiconductor or an insulator, wherein the measuring part of the capacitive proximity switch is usually a plate constituting a capacitor, and the other plate is the outer shell of the switch, which is usually grounded or connected to the housing of the device during the measurement process. When an object moves toward the proximity switch, regardless of whether it is a conductor, its proximity will always cause the dielectric constant of the capacitor to change, thereby causing the capacitance to change, and then generating the required detection signal.
[0039] The other structures of this embodiment are the same as those of Embodiment 1 and will not be described again here.
[0040] Example 3
[0041] Different from the first embodiment, the first sensor 11 is a Hall switch, and the sensing element 31 is a conductor or a semiconductor. When a metal or semiconductor sheet with current flowing through it is placed vertically in a magnetic field, a potential difference will be generated at both ends of the sheet, forming a physical Hall effect. By obtaining such a potential difference signal, the required detection can be effectively achieved.
[0042] The other structures of this embodiment are the same as those of Embodiment 1 and will not be described again here.
[0043] Example 4
[0044] Different from the first embodiment, the first sensor 11 is a photoelectric proximity switch, and the sensing element 31 is a conductor, a semiconductor or an insulator, wherein the first sensor 11 can be changed from the cylindrical structure of the first embodiment to two flat plate structures arranged oppositely and alternately along the same horizontal line, and the photoelectric proximity switch uses the shielding or reflection of the light beam by the detected object, and then connects the circuit by the synchronous circuit to detect the presence or absence of the object. The detected object is not limited to metal, and all objects that can reflect light (or have a shielding effect on light) can be detected. During operation, the photoelectric proximity switch converts the input current into an optical signal on the transmitter set in the component, and the receiver set in the component detects the target object according to the strength or presence of the received light, and the photoelectric proximity switch can transmit the signal to the PLC controller, thereby controlling the timely stop of the clamping component.
[0045] The other structures of this embodiment are the same as those of Embodiment 1 and will not be described again here.
[0046] Example 5
[0047] A battery cell clamping device comprises the clamping assembly of any one of embodiments 1 to 4.
[0048] Specifically, the clamping device is also provided with an alarm device electrically connected to the first sensor 11. When the battery cell is pressed to a corner position, the sensor in the device can detect the pressing material, thereby stopping the pressing and alarming in time, effectively preventing the battery cell from being further crushed by the corner force, thereby forming a clamp device that prevents the battery cell from being crushed.
[0049] The clamping assembly can also be installed in a robot to perform clamping operations.
[0050] It can be seen that the utility model can effectively reduce the force when the corners of the battery cell are under pressure, prevent the corners of the battery cell from being crushed, reduce the scrapping of the battery cell, and improve the production efficiency. Moreover, it has a high degree of controllability and intelligence. Through collaborative control through PLC, when material compression occurs, the corresponding components can be shut down in time and alarms can be sounded, reminding the operator to deal with it in time.
[0051] According to the disclosure and teaching of the above description, those skilled in the art to which the utility model belongs can also change and modify the above implementation. Therefore, the utility model is not limited to the above specific implementation, and any obvious improvement, replacement or modification made by those skilled in the art on the basis of the utility model belongs to the protection scope of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
