In the conveying process, a shell of a workpiece (such as a battery) is easy to rub with conveying equipment such as pushing equipment and positioning equipment, so that the shell of the workpiece is scratched, and the quality of the workpiece is influenced. For avoiding the work piece to take place the scotch phenomenon in the transportation as far as possible, this application provides a strutting arrangement.

Referring to fig. 1, the supporting device 10 includes a pad 200, a first sliding member 300, a base 400, and a return elastic member 500. Wherein the spacer 200 is used to support the workpiece 100 (e.g., a battery). During transport (e.g., positioning), the workpiece 100 may be placed on top of the pad 200 and the workpiece 100 may then be pushed to effect the transport operation. One side of the first sliding member 300 can be fixedly arranged at the bottom of the cushion block 200 by means of fastening, welding and the like; the other side of the first sliding member 300 is slidably disposed on the base 400, and the first sliding member 300 can slide back and forth along the first direction a relative to the base 400, so that in the process of pushing the workpiece 100 to move, the pad 200 can slide along with the workpiece 100 along the first direction a under the action of the first sliding member 300, thereby avoiding the situation that the workpiece 100 moves and the pad 200 is fixed, that is, avoiding the contact part between the workpiece 100 and the pad 200 from being scratched due to the relative movement between the workpiece 100 and the pad 200, and affecting the quality of the workpiece 100.

It should be noted that the first sliding member 300 can be directly or indirectly slidably disposed on the base 400, as long as the cushion block 200 can be slid back and forth along the first direction a relative to the base 400. In some embodiments, when the first sliding member 300 is directly slidably disposed on the base 400, a sliding slot may be disposed on the first sliding member 300 along the first direction a, a sliding rail may be disposed on the base 400 along the first direction a, and the sliding rail on the base 400 is engaged with the sliding slot of the first sliding member 300, so that the first sliding member 300 can only slide along the first direction a relative to the base 400. In other embodiments, a slide rail may be disposed on the first sliding member 300 along the first direction a, a slide groove may be disposed on the base 400 along the first direction a, and the slide rail of the first sliding member 300 is engaged with the slide groove of the base 400.

The supporting device 10 further includes a return elastic member 500, the return elastic member 500 connects the pad 200 and the base 400, and the return elastic member 500 can provide an elastic force to the pad 200 to return the slid pad 200 to an initial position. In some embodiments, when the return spring 500 is in a free state (providing no spring force to the cushion block 200) or an equilibrium state (when the return spring 500 includes at least two spring elements, the total spring force of the spring elements applied to the cushion block 200 is zero), the position of the cushion block 200 relative to the base 400 is an initial position. When the workpiece 100 moves and drives the pad 200 to move (i.e., the pad 200 deviates from the initial position), the elastic restoring member 500 is no longer in a free state or a balanced state, and at this time, the elastic restoring member 500 applies an elastic force to the pad 200 opposite to the moving direction. Subsequently, when the workpiece 100 is removed from the top of the pad 200, the pad 200 is returned to the initial position by the elastic force provided by the return elastic member 500 (i.e., the above-mentioned reverse force), so that the next workpiece 100 can be transported. Compared with a cylinder type reset structure adopted by other devices, the reset elastic member 500 can simplify the reset structure of the support device 10, and simultaneously, the structure of the support device 10 is prevented from being too bulky by providing an elastic force to reset the cushion block 200.

Referring to fig. 1, 2 and 3, in some embodiments, the supporting device 10 further includes a second slider 600, the second slider 600 is disposed between the first slider 300 and the base 400, one side of the second slider 600 is directly connected to the base 400 in a sliding manner, and the other side of the second slider 600 is connected to the first slider 300 in a sliding manner. The second slider 600 is slidable back and forth relative to the base 400 in a second direction B, and the first slider 400 is slidable back and forth on the second slider 600 in a first direction a, wherein the first direction a and the second direction B are perpendicular to each other. Therefore, under the action of the first slider 300 and the second slider 600, the pad block 200 can slide back and forth along the first direction a and the second direction B, so that when the workpiece 100 placed on the pad block 200 is pushed along the first direction a and the second direction B, the pad block 200 can move along with the workpiece 100 along the two directions, and the relative movement between the two is prevented, thereby reducing the possibility of scratching of the workpiece 100. The moving mode can be firstly moving along the first direction A and then moving along the second direction B; or firstly moving along the second direction B and then moving along the first direction A; or in both the first and second directions a and B.

Referring to fig. 4, in particular, in some embodiments, a side of the first slider 300 close to the second slider 600 is provided with a first sliding groove 310 along the first direction, a side of the second slider 600 close to the first slider 300 is provided with a first sliding rail 610 along the first direction, and the first sliding rail 610 is snapped into the first sliding groove 310, so that the first slider 300 can slide along the first sliding rail 610 (the first direction). Preferably, in order to make the first sliding member 300 not easily fall off when sliding on the first sliding rail 610, the first sliding slot 310 is provided with first protrusions 311 on two opposite sides, the first sliding rail 610 is provided with first guide slots 611 on two opposite sides, and the first protrusions 311 can be snapped into the first guide slots 611, so that the first sliding member 300 can stably slide on the first sliding rail 610.

By adopting the above-described structure, the first slider 300 can be slid on the second slider 600 more accurately.

It should be noted that, in some embodiments, the first slide rail 610 on the second slider 600 may be replaced by a slide slot disposed along the same direction (the first direction), and the first slider 300 is replaced by a slide rail capable of being snapped into the slide slot of the second slider 600.

Referring to fig. 5, 6 and 7 (fig. 7 only shows a partial structure of the supporting device 10), specifically, in some embodiments, the base 400 is provided with a second sliding rail 410 along the second direction, a side of the second sliding member 600 close to the base 400 is provided with a second sliding slot 620 along the second direction, and the second sliding rail 410 is snapped into the second sliding slot 620, so that the second sliding member 600 can only slide along the second sliding rail 410, that is, the second sliding member 600 can slide along the second sliding rail 410 (the second direction). Preferably, in order to make the second sliding member 600 not easily fall off when sliding on the second sliding rail 410, the two opposite sides of the second sliding rail 410 are provided with the second guide slot 411, the two opposite sides of the second sliding slot 620 are provided with the second protrusion 621, and the second protrusion 621 can be snapped into the second guide slot 411, so that the second sliding member 600 can stably slide on the second sliding rail 410. In other embodiments, protrusions may be disposed on two opposite sides of the second sliding rail 410, guide grooves may be disposed on two opposite sides of the second sliding groove 620, and the protrusions on the second sliding rail 410 may be snapped into the guide grooves of the second sliding groove 620. By adopting the above-described structure, the second slider 600 can slide on the base 400 more accurately.

It should be noted that in some embodiments, the second slide rail 410 on the base 400 can be replaced by a guide slot arranged along the same direction (the second direction), and the second slider 600 can be snapped into the guide slot of the base 400, so that the second slider 600 can move along the guide slot of the base 400.

In the sliding groove structure and the sliding rail structure of each embodiment, the sliding groove can also have a structure that the width of the groove top is smaller than that of the groove bottom, and the shape of the sliding rail is matched with that of the sliding groove, so that the sliding rail can be stably clamped in the sliding groove in a sliding manner and is not easy to separate.

Referring to fig. 3 again, in some embodiments, in order to reduce the friction force applied to the first sliding member 300 and/or the second sliding member 600 and make the sliding of the pad block smoother, a plurality of first sliding members 300 or a plurality of first sliding members 300 and a plurality of second sliding members 600 may be disposed in the supporting device 10. Preferably, in some embodiments, the number of the first slider 300 and the second slider 600 is two, the two second sliders 600 are spaced apart from each other, and the two first sliders 300 are respectively disposed on the two second sliders 600. When the two second guide rails 410 are disposed on the base 400, the two second guide rails 410 are parallel to each other and disposed at an interval, and the two second sliders 600 are disposed on the two second slide rails 410, respectively. In other embodiments, in order to make the structure of the supporting device 10 simpler, only one expansion spring may be disposed in the supporting device 10 as the return elastic member 500, and at this time, when the resultant force of the acting force of the expansion spring on the cushion block 200 is zero, the cushion block 200 is at the initial position; when the pad 200 moves along with the workpiece 100, the extension spring is stretched, so as to provide a pulling force (elastic force) to the pad 200 opposite to the moving direction, thereby driving the pad 200 to return to the initial position.

In some embodiments, the return spring 500 comprises a plurality of extension springs, one end of each extension spring is connected to the base 400, and the other end of each extension spring is connected to the pad 200, and the plurality of extension springs are arranged to provide sufficient spring force to the pad 200 to enable the pad 200 to return to the initial position more quickly.

In some embodiments, referring to fig. 1, the axial direction (long axis direction) of the plurality of extension springs is inclined with respect to the base 400, and the inclined structure can facilitate the extension springs to be installed between the spacer 200 and the base 400.

Specifically, referring to fig. 1 and 2, the number of the extension springs in some embodiments is two, and the first extension spring 510 and the second extension spring 520 are respectively capable of elastically extending and contracting in the long axis direction thereof. One end of the first extension spring 510 is connected with the cushion block 200, and the other end is connected with the base 400; one end of the second extension spring 520 is connected to the pad 200, and the other end is connected to the base 400. The first and second extension springs 510 and 520 are each capable of applying elastic force in the first and second directions to the pad 200, thereby providing elastic force required for pad return. By providing two extension springs, the return structure in the support device 10 can be greatly simplified.

Referring to fig. 7, an orthographic projection of the first expansion spring 510 on the base 400 is a first orthographic projection, and an orthographic projection of the second expansion spring 520 on the base 400 is a second orthographic projection. In some embodiments, the first orthographic projection and the second orthographic projection are parallel to each other. In some embodiments, the first orthographic projection is collinear with the second orthographic projection. The above relationship can simplify the positional relationship between the first and second extension springs 510 and 520, simplify the return structure, and reduce the maintenance cost.

In some embodiments, when the cushion block 200 is in the initial position, the first and second expansion springs 510 and 520 are in a stretched state, and the elastic forces applied to the cushion block 200 by the first and second expansion springs 510 and 520 are balanced, i.e., the resultant elastic forces of the expansion springs applied to the cushion block 200 in the first and second directions a and B are zero. In other embodiments, when the pad 200 is in the initial position, the first and second extension springs 510 and 520 are both in a free state, and neither of the first and second extension springs 510 and 520 exert a resilient force on the pad 200.

Referring to fig. 1, in some embodiments, to facilitate the engagement and assembly of the first and second extension springs 510 and 520, a spring support 210 is also provided at the bottom of the spacer 200. Preferably, the spring support 210 is disposed at a central position of the bottom of the pad 200. One ends of the first and second extension springs 510 and 520 are coupled to the spring support 210 at the bottom of the pad 200. By providing the spring support column 210 and connecting the extension spring to the spring support column 210, the structure of the support device 10 can be prevented from being too bulky, the movement flexibility of the spacer 200 can be improved, and the maintenance cost can be reduced.

Referring to fig. 6, in other embodiments, one end of the first and second extension springs 510 and (not shown) may be connected to the sidewall of the pad 200.

Referring to fig. 8 and 9, the support device 10 may be employed in a positioning apparatus 20 to position a workpiece (e.g., a battery). The positioning apparatus 20 further includes a first movable platen 811 and a first fixed platen 812 that are disposed in opposition (disposed on both sides of the workpiece 100 in the first direction a), and a second movable platen 821 and a second fixed platen 822 that are disposed in opposition (disposed on both sides of the workpiece 100 in the second direction B). In some embodiments, the first movable platen 811 is movable in the first direction a, the first movable platen 811 being capable of urging the workpiece 100 in the first direction a toward the first fixed platen 812; the second movable platen 821 is movable in the first direction a and the second direction B, the second fixed platen 822 is movable in the first direction a, and the second movable platen 821 is capable of pushing the workpiece 100 toward the second fixed platen 822 in the second direction B. In some embodiments, the second movable platen 821 pushes the workpiece 100 toward the second fixed platen 822 in the second direction B, and then the first movable platen 811 pushes the workpiece 100, the second movable platen 821, and the second fixed platen 822 together toward the first fixed platen 812 in the first direction a, thereby clamping and positioning the workpiece 100 in the first direction a and the second direction B. During the pushing of the workpiece 100, the pad 200 can move together with the workpiece 100. After clamping the workpiece 100, the first movable pressing plate 811, the first fixed pressing plate 812, the second movable pressing plate 821 and the second fixed pressing plate 822 can clamp the workpiece 100 at a preset position, so as to process the workpiece 100, and after the processing is completed, the workpiece 100 is taken away from the spacer 200, and then the spacer 200 is reset to an initial position under the action of the reset elastic members (such as the first expansion spring 510 and the second expansion spring 520). The positioning device 20 can effectively prevent the workpiece 100 and the cushion block 200 from moving relatively during the positioning process of the workpiece 100, so as to reduce the scratch of the workpiece 100 during the positioning process.

In other embodiments, the first stationary platen 812 may also be arranged such that the first stationary platen 812 is capable of moving in the second direction B. At this time, the first movable platen 811 pushes the workpiece 100 in the first direction a toward the first fixed platen 812, and then the second movable platen 821 pushes the battery, the first movable platen 811, and the first fixed platen 812 together in the second direction B toward the second fixed platen 822.

Referring again to fig. 3, in some embodiments, the positioning apparatus further comprises a base 700, a guide bearing 710, a lift lever 720, and a compression spring 730. The base 700 is disposed at the other side of the base 400 opposite to the pad 200, the guide bearing 710 is disposed on the base 700, the lifting rod 720 passes through the guide bearing 710 and is connected with one end of the compression spring 730, and the other end of the compression spring 730 is connected with the base 400. The lifting rod 720 can drive the base 400 to lift, so as to drive the cushion block 200 and the workpiece 100 to lift, and the workpiece 100 has a moving capability in a third direction (perpendicular to the first direction a and the second direction B); the guide bearing 710 can guide the lifting direction of the lifting rod 720, so that the operation of the lifting rod 720 is more accurate. When further positioning of the workpiece 100 in the third direction is desired, an upper positioning mechanism may be provided to press down (in a direction from the block 200 toward the base 700) any of the workpiece 100, the block 200, or the base 400 in the third direction. At this time, due to the characteristic that the compression spring 730 can be compressed, the workpiece 100 can still be pressed downwards in the third direction by the upper positioning mechanism under the condition that the lifting rod 720 is not lifted any more, so that the positioning is realized, and the lifting process is simplified. In addition, when the workpiece 100 is placed on the pad 200, the compression spring 730 also has a buffering function to prevent the workpiece 100 from directly impacting the pad 200, thereby protecting the workpiece 100. It should be noted that in some embodiments, the base 700 and the guide bearing 710 may be omitted to simplify the structure of the positioning apparatus.

In some embodiments, the positioning apparatus may position the battery by:

driving the lift lever to raise the mat, and then preventing the battery from being placed on the mat;

then, the second movable pressing plate pushes the battery to the second fixed pressing plate along the second direction, and the battery and the second fixed pressing plate clamp the battery together;

the first movable pressing plate pushes the battery, the second movable pressing plate and the second fixed pressing plate to the first fixed pressing plate along the first direction, so that the battery is clamped and positioned in the first direction and the second direction, and the cushion block moves along with the battery in the process of pushing the battery;

the battery is pressed down to a preset position through the upper positioning mechanism so as to realize positioning in a third direction;

processing the battery, and separating the battery from the cushion block after the processing is finished;
