Referring to fig. 1, a jig 10 according to an embodiment is used for positioning an insulating plate 11 before assembling a module battery, and the jig 10 includes a mount 100, a first positioning mechanism 200, a second positioning mechanism 300, and a driving mechanism 400. The mounting base 100 is used for providing mounting space for each mechanism, and specifically, the first positioning mechanism 200, the second positioning mechanism 300 and the driving mechanism 400 are mounted on the mounting base 100 at intervals. The first positioning mechanism 200 and the second positioning mechanism 300 are respectively used for abutting against different edges of the insulating plate 11 so as to position the insulating plate 11.
As shown in fig. 2 and 4, the mounting base 100 is provided with a mounting plate 110 capable of moving up and down, and the mounting plate 110 is connected to an output end of the driving mechanism 400, so that the mounting plate 110 can move up and down relative to the mounting base 100 along a first direction (refer to an x direction in fig. 2) under the driving of the driving mechanism 400.
In some embodiments, the driving mechanism 400 may be a cylinder, a cylinder body of the cylinder is mounted to the mounting base 100, and a telescopic rod of the cylinder is connected to the mounting plate 110 through a floating joint 410, so that when the telescopic rod of the cylinder moves telescopically relative to the cylinder body, the mounting plate 110 can be driven to move up and down relative to the mounting base 100.
It should be noted that, in order to improve the stability, smoothness and stroke accuracy of the lifting motion of the mounting plate 110 relative to the mounting base 100. In some embodiments, the mounting base 100 is provided with four linear bearings 120, one side of the mounting plate 110 close to the mounting base 100 is provided with four lifting rods 130 corresponding to the linear bearings 120, the lifting rods 130 are sleeved with the linear bearings 120, and the sliding connection between the mounting plate 110 and the mounting base 100 is realized through the cooperation of the lifting rods 130 and the linear bearings 120. In this embodiment, the extending direction of the liftable rod 130 is the first direction, so that the mounting plate 110 can be lifted and lowered relative to the mounting base 100 under the driving of the driving mechanism 400.
Referring to fig. 2, the first positioning mechanism 200 includes a first positioning block 220 and a first limiting plate 230.
The first positioning block 220 is slidably connected to the mounting plate 110 and can slide along a second direction (refer to the y direction in fig. 2), which is perpendicular to the first direction, for example, the first direction is a vertical direction, and the second direction is a horizontal direction.
The first limiting plate 230 is installed on the installation base 100 and is arranged opposite to the first locating block 220, so that when the first locating block 220 slides on the installation plate 110, the first locating block 220 can be close to or far away from the first limiting plate 230 arranged opposite to the first locating block 220, and the requirement for clamping and locating the long edge of the insulating plate 11 is met.
In this embodiment, a first linkage assembly is disposed between the first positioning block 220 and the mounting base 100. When the mounting plate 110 moves relative to the mounting base 100 along the first direction, the first linkage assembly can drive the first positioning block 220 to slide relative to the mounting plate 110 along the second direction.
As shown in fig. 2 and fig. 3, the first linkage assembly includes a first abutting member 260 and a first connecting plate 270, at least one of the first abutting member 260 and the first connecting plate 270 has an abutting surface inclined relative to the first direction, and the first abutting member 260 and the first connecting plate 270 slidably abut against the abutting surface. One of the first abutting member 260 and the first connecting plate 270 is connected to the first positioning block 220, and the other is connected to the mounting base 100, so that when the mounting plate 110 drives the first positioning block 220 to move up and down relative to the mounting base 100, the first abutting member 260 and the first connecting plate 270 slide along the abutting surface, and because the abutting surface is inclined, the first positioning block 220 is driven to move along the second direction relative to the mounting plate 110 when the first abutting member 260 and the first connecting plate 270 slide along the abutting surface.
For convenience of understanding, the first linkage assembly will be further described below by taking as an example only that the first abutting member 260 is mounted on the mounting base 100, and the first connecting plate 270 is connected to the first positioning block 220 and has a first inclined surface 280 inclined relative to the first direction.
As shown in fig. 2 and 3, when the mounting plate 110 moves downward along a first direction (i.e., an x direction in fig. 3) relative to the mounting base 100, the first connecting plate 270 moves together toward the mounting base 100, and at this time, the first abutting member 260 fixed on the mounting base 100 abuts against the first inclined surface 280 of the first connecting plate 270, so that during the downward movement of the mounting plate 110, the first connecting plate 270 moves toward a side away from the mounting plate 110, and further drives the first positioning block 220 to slide along a second direction (i.e., a y direction in fig. 3) relative to the mounting plate 110.
In the above embodiment, the lifting motion of the mounting plate 110 in the first direction is converted into the translational motion of the first positioning block 220 in the second direction by the first linkage assembly, so that the first positioning block 220 is close to the first limiting plate 230 to clamp and position one edge of the insulating plate 11.
With continued reference to fig. 3, the first positioning mechanism 200 further includes a first slide bar 240 and a first elastic member 250. The mounting plate 110 is provided with a limiting through hole 211, and the first sliding rod 240 penetrates through the limiting through hole 211 along a second direction, which is the central axis direction of the first sliding rod 240. The first connecting plate 270 is fixed at one end of the first sliding bar 240, the first positioning block 220 is disposed on the top surface of the first connecting plate 270 to move along with the first sliding bar 240, the other end of the first sliding bar 240 is sleeved with a first elastic member 250, and the first elastic member 250 is connected to the first sliding bar 240 and the mounting plate 110.
Further, the first elastic element 250 is a compression spring, and can elastically act on the mounting plate 110 to move the mounting plate 110 along the first sliding rod 240 toward the first limiting plate 230, so as to drive the first positioning block 220 to approach the first limiting plate 230. Because the elastic action of the first elastic member 250 can make the first abutting member 260 and the first inclined surface 280 elastically abut, the first abutting member 260 can drive the first sliding rod 240 to move along the second direction when sliding along the first inclined surface 280, so that the driving mechanism 400 drives the mounting plate 110 to move linearly along the first direction relative to the mounting seat 100, and the first connecting plate 270 drives the first positioning block 220 to be close to the first positioning plate 230 to position the long edge of the insulating plate 11 during the movement of the mounting plate 110 along the first direction.
In other embodiments, the first elastic element 250 may also be an extension spring, and only the elastic force provided by the first elastic element 250 needs to drive the first sliding rod 240 to drive the first connecting plate 270, so that the first connecting plate 270 and the first abutting element 260 keep sliding and abutting, so that when the mounting plate 110 moves relative to the mounting base 100, the first abutting element 260 always abuts against the first inclined surface 280 of the first connecting plate 270, and further the first connecting plate 270 drives the first positioning block 220 to move relative to the mounting plate 110 to be close to or far away from the first limiting plate 230, thereby adapting to the requirement of clamping or loosening the workpiece such as the insulating plate 11.
In one embodiment, the first inclined plane 280 is disposed at the inner side of the first connecting plate 270, and during the process that the first connecting plate 270 approaches the mounting seat 100 along the first direction, the first abutting member 260 pushes the first connecting plate 270 along the second direction, so as to convert the motion perpendicular to the top surface of the mounting seat 100 into the motion parallel to the top surface of the mounting seat 100.
Specifically, the first abutting member 260 adopts a cam follower, a pin shaft of the cam follower is connected with the mounting base 100 through a wheel frame 260a, and the outer peripheral wall of the rotor of the cam follower abuts against the first inclined surface 280, so that the first abutting member 260 slides more smoothly along the first inclined surface 280, and the failure rate of the device can be effectively reduced.
Referring to fig. 2, the second positioning mechanism 300 includes a second positioning block 310 and a second limiting plate 320.
The second positioning block 310 is slidably mounted on the mounting plate 110, and the second positioning block 310 can slide on the mounting plate 110 along a third direction, which is perpendicular to the first direction. In some embodiments, the third direction is perpendicular to the second direction, and the third direction is perpendicular to the first direction, i.e., the first direction, the second direction, and the third direction are perpendicular to each other. The second position limiting plate 320 is mounted on the mounting base 100 and is opposite to the second positioning block 310, and the second positioning block 310 can slide close to the second position limiting plate 320, so as to position the short side of the insulating plate 11.
The second limiting plate 320 is connected to the mounting seat 100 through the supporting plate 380, so that the mounting heights of the second limiting plate 320 and the second positioning block 310 relative to the mounting plate 110 are equivalent, so as to more stably clamp the insulating plate 11.
It is understood that the second positioning mechanism 300 may adopt the same structure as the first positioning mechanism 200, and the conversion of the lifting motion of the mounting plate 110 in the first direction into the translational motion of the second positioning block 310 in the third direction is realized through the structure similar to the first linkage assembly, so as to meet the requirement of clamping the short side of the insulating plate 11. In this embodiment, the structure of the second positioning mechanism 300 refers to the structure of the first positioning mechanism 200, and the linkage structure between the second positioning block 210 and the mounting base 100 refers to the first linkage assembly, which is not described herein again.
In other embodiments, the second positioning mechanism 300 may take on a different configuration than the first positioning mechanism 200. For example, the second positioning mechanism 300 further includes a second linkage assembly, which has a similar structure to the first linkage assembly, and is different from the first linkage assembly in that the second linkage assembly may be disposed between the first slide bar 240 and the second positioning block 210, and when the first slide bar 240 moves in the second direction, the second positioning block 210 is driven to move in the third direction through the second linkage assembly.
Specifically, as shown in fig. 5 and 6, the second linkage assembly includes a sliding block 330, a second abutting member 340, and a second connecting plate 350. The sliding block 330 is slidably disposed on the bottom surface of the mounting plate 110, the second positioning block 310 is connected to the sliding block 330, the second abutting member 340 is mounted on the sliding block 330, the second connecting plate 350 is connected to the first sliding rod 240, the second connecting plate 350 has a second inclined surface 351 inclined with respect to the second direction, the second abutting member 340 is slidably abutted to the second inclined surface 351, so that when the second connecting plate 350 moves along the first sliding rod 240 in the second direction, the second abutting member 340 slides along the second inclined surface 351 with respect to the second connecting plate 350, so that the sliding block 330 connected to the second connecting plate 350 slides along the third direction with respect to the mounting plate 110, and the sliding block 330 drives the second positioning block 310 to approach the second limiting plate 320, so that the second positioning block 310 is matched with the second limiting plate 320 to position the short side of the insulating plate 11.
In some embodiments, the second positioning mechanism 300 includes a second elastic member 360 and a fixing block 370. The fixing block 370 is installed on the mounting plate 110, two ends of the second elastic member 360 are respectively connected to the fixing block 370 and the second positioning block 310, and the second elastic member 360 can drive the second positioning block 310 to slide along the third direction relative to the mounting plate 110, so that the second positioning block 310 is close to the second limiting plate 320 to position the short side of the insulating plate 11.
In this embodiment, the second abutting member 340 can keep elastically abutting against the second inclined surface 351 due to the elastic action of the second elastic member 360. Therefore, the first sliding rod 240 drives the second connecting plate 350 to perform a linear motion along the second direction, so that the second abutting member 340 can drive the sliding block 330 to move along the third direction when sliding along the second inclined plane 351. In this embodiment, when the driving mechanism 400 drives the mounting plate 110 to move up and down along the first direction relative to the mounting base 100, the second connecting plate 350 drives the second positioning block 310 to approach the second limiting plate 320 to position the short side of the insulating plate 11 during the movement of the first sliding rod 240 along the second direction.
It should be noted that the avoiding groove 140 is formed in the bottom surface of the mounting plate 110, a part of the first sliding rod 240 penetrates through the avoiding groove 140, and a part of the second connecting plate 350 is accommodated in the avoiding groove 140, so that the occupied space of the second connecting plate 350 is reduced, the overall size of the clamp 10 is reduced, and the second connecting plate 350 can be prevented from interfering with the second elastic member 360 or other structures.
With continued reference to fig. 5, a guide rail 390 is disposed between the sliding block 330 and the mounting plate 110, and the sliding block 330 is slidably connected to the mounting plate 110 through the guide rail 390, i.e. the third direction is along the length of the guide rail 390. To ensure the structural strength of the device, the slide rails may preferably employ cross roller guides 390. During movement of the mounting plate 110 away from the first connecting plate 270, the second connecting plate 350 pushes the slider 330 in the third direction via the second inclined surface 351. The second abutting member 340 preferably adopts a radial bearing, and the outer peripheral wall of the radial bearing abuts against the second inclined surface 351, so that the second abutting member 340 can slide more smoothly along the second inclined surface 351, and the failure rate of the device can be effectively reduced.
In other embodiments, in order to adapt the apparatus to insulating plates 11 with different sizes, the first positioning block 220 and the second positioning block 310 are provided with kidney-shaped holes (not shown), so that the positions of the first positioning block 220 and the second positioning block 310 can be adjusted according to actual needs.
In order to improve the automation degree of the equipment, as shown in fig. 7, a sensor 500 may be disposed on the mounting base 100, the sensor 500 is usually a photoelectric sensor 500, the sensor 500 is used to detect whether the insulating plate 11 is placed on the side of the mounting plate 110 away from the mounting base 100, and transmit the signal to the control mechanism in real time, and the control mechanism analyzes and judges the signal according to the received signal, and then controls the driving mechanism 400 to operate, so as to realize automatic positioning of the insulating plate 11.
Before the jig 10 positions the insulating plate 11, the piston rod of the driving mechanism 400 is in a retracted state, that is, the first positioning block 220 and the second positioning block 310 in the first positioning mechanism 200 and the second positioning mechanism 300 are located away from the mounting plate 110. At this time, the insulating plate 11 is placed on the mounting plate 110, after the sensor 500 detects that there is the insulating plate 11, the piston rod in the cylinder extends out, the mounting plate 110 moves upward, the first inclined plane 280 slides along the first abutting member 260, and under the elastic action of the first elastic member 250, the first positioning block 220 slides toward the direction close to the first limiting plate 230, so as to clamp and position the long edge of the insulating plate 11. When the first positioning hole 220 moves, the first sliding rod 250 moves synchronously, and the second connecting plate 350 fixed on the first sliding rod 250 moves, so that the second inclined plane 351 slides along the second abutting part 340, and under the elastic action of the second elastic part 360, the second positioning block 310 slides towards the direction close to the second limiting plate 320, so that the short side of the insulating plate 11 is clamped and positioned, and the insulating plate 11 is positioned. After positioning, the piston rod of the cylinder is retracted, so that the first positioning mechanism 200 and the second positioning mechanism 300 are in an open state, the external mechanism takes away the insulation board 11, positioning operation is completed, and the equipment reciprocates in a circulating manner to position the insulation board 11.
In the above-mentioned clamp 10, when the driving mechanism 400 drives the mounting plate 110 to move along the first direction, the first linkage assembly can drive the first positioning block 220 to move along the second direction, and the second linkage assembly can drive the second positioning block 310 to move along the third direction, the long edge and the short edge of the insulating plate 11 can be positioned only by setting one driving mechanism 400 for driving, the equipment structure is compact, the electric equipment is less, the occupied space is small, the power consumption is low, the use cost is low, and the benefits of production enterprises are improved.
In one embodiment, a welding device is provided for welding the insulating plate 11 of the module battery, the welding device comprises the fixture 10, and the fixture 10 is transferred to the module battery after positioning the insulating plate 11 and finally is welded and fixed by a welding head.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above examples only represent some embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention.
