For ordinary skilled in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to the specific circumstances.

[0043] The embodiments of the utility model are described in detail below, the examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar function throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the utility model, and cannot be understood as the limitation of the utility model.

[0044] As Figure 1 and Figure 2 shown, the embodiment first provides a multi-model side plate feeding and positioning conversion equipment, including conveying line 1, conveying line 1 is used to convey horizontal state side plate. The side plate has a flange folded towards the inner side, and the flange includes an inner flange 1001 and an outer flange 1002 (refer to Figure 9 ) oppositely arranged along the width direction of the side plate.

[0045] The multi-model side plate feeding and positioning conversion equipment provided by the embodiment further comprises a grabbing assembly 2 and a turnover assembly 3, the turnover assembly 3 comprises two groups of turnover mechanisms 31, the grabbing assembly 2 can simultaneously grab two adjacent side plates on the conveying line 1 and place the two side plates on the two groups of turnover mechanisms 31 respectively. Each side plate is positioned on the turnover mechanism 31 through the outer side surface and the outer flange 1002, the conversion of the positioning reference is completed, and the multi-model side plate can be applied to side plates of multiple different widths. The turnover mechanism 31 can turn the side plate in the horizontal state into the vertical state; because the rotation directions of the two groups of turnover mechanisms 31 are opposite, the flanges of the two side plates in the vertical state are oppositely arranged, which facilitates subsequent assembly. The outer flanges 1002 of the two side plates are located in the same plane, and the outer side surface of each side plate is adjusted and positioned on the turnover mechanism 31, so that the outer flange 1002 and the outer side surface can be used as the positioning reference in subsequent processing. The multi-model side plate feeding and positioning conversion equipment of the embodiment can complete the turnover and positioning reference adjustment of two side plates in the same box shell at a time, greatly shortens the production rhythm of the box shell assembly production line, improves the production efficiency, reduces the production cost, and has good applicability.

[0046] The conveying line 1 conveys multiple side plates, as shown in Figures 2 to 4 Any two adjacent side plates in the multiple side plates form a first side plate 101 and a second side plate 102, and the first side plate 101 and the second side plate 102 form two side plates of the same box shell. The inner flanges 1001 of the first side plate 101 and the second side plate 102 are oppositely arranged, two first positioning members 11 are arranged on the conveying line 1, and the inner flanges 1001 of the first side plate 101 and the second side plate 102 abut against the two first positioning members 11 respectively to constrain the distance between the two inner flanges 1001. The positions and intervals of the two first positioning members 11 on the conveying line 1 are adjusted, so that the positioning accuracy of the conveying line 1 to the side plate can be improved, and the first side plate 101 and the second side plate 102 are positioned in the width direction through the two first positioning members 11 with the same interval, so that the positioning requirement of the side plate after the punching line processing can be met.

[0047] Figure 2 The same first positioning member 11 on one side of the same first positioning member 11 shows multiple side plates of different models. As can be seen, even if the widths of the side plates of different models are different, the inner flanges 1001 are positioned by abutting against the first positioning member 11. That is, the interval between the inner flanges 1001 of the first side plate 101 and the second side plate 102 on the conveying line 1 is always the same.

[0048] The specific conveying structure of the conveying line 1 and the number of conveyable side plates can be set according to the prior art. Exemplarily, in an embodiment, the conveying line 1 is a ring-shaped conveying synchronous belt, and six groups of positioning member groups are uniformly arranged along one circumference of the ring-shaped conveying synchronous belt (for reference Figure 4), each group of positioning members includes two first positioning members 11, Figure 4 Three groups of positioning members are shown in the middle, and the other three groups are on the lower side of the annular conveying synchronous belt. The two first positioning members 11 position the first side plate 101 and the second side plate 102 respectively, so that the distance between the inner folded edge 1001 of the first side plate 101 and the inner folded edge 1001 of the second side plate 102 is consistent, thereby ensuring that the first side plate 101 and the second side plate 102 do not slip relative to the conveying line 1 when being conveyed. The conveying line 1 has at most three groups of first side plates 101 and second side plates 102 at the same time, as shown in Figure 1 .

[0049] The first positioning member 11 has a V-shaped groove, and the inner folded edge 1001 can be embedded in the V-shaped groove to constrain the side plate from moving in the width direction. In addition, the conveying line 1 has a baffle 12 on both sides, and the baffle 12 on both sides abuts against the two ends of the side plate in the length direction, so that the side plate is completely limited in the horizontal plane on the conveying line 1. As shown in Figure 5 , the upper end of the baffle 12 extends outwardly of the conveying line 1, so that the opening size between the baffles 12 on both sides is slightly larger than the length size of the side plate, facilitating accurate placement of the side plate in the position of the first positioning member 11.

[0050] In order to grasp the side plate on the conveying line 1 and at the same time adjust the side plate on the conveying line 1 with the inner folded edge 1001 as the positioning reference to the outer folded edge 1002 as the positioning reference, the multi-model side plate feeding and positioning conversion equipment provided by the embodiment further comprises a jacking positioning assembly 4. As shown in Figure 6 , the jacking positioning assembly 4 comprises two jacking mechanisms 41, two pushing mechanisms 42 and two groups of second positioning members, the two pushing mechanisms 42 and the two groups of second positioning members are one-to-one corresponding and oppositely arranged, and each group of second positioning members comprises two second positioning members 43. The two jacking mechanisms 41 respectively jack up the first side plate 101 and the second side plate 102 to separate from the conveying line 1, the two pushing mechanisms 42 respectively push the first side plate 101 and the second side plate 102 in opposite directions, and the outer folded edge 1002 of the first side plate 101 and the outer folded edge 1002 of the second side plate 102 respectively abut against the corresponding second positioning member group to constrain the distance between the two outer folded edges 1002. Through the two groups of second positioning members, the first conversion of the positioning reference can be realized. At the same time, the first side plate 101 and the second side plate 102 are separated from the conveying line 1 by the jacking mechanism 41, and the first side plate 101 and the second side plate 102 in the static state are easier to grasp. The distance between the two groups of second positioning members is set as a fixed value, and through the control of the distance accuracy, the position accuracy of the outer folded edge 1002 of the first side plate 101 and the outer folded edge 1002 of the second side plate 102 and the distance accuracy between the two outer folded edges 1002 are ensured.

[0051] The jacking mechanism 41 and the pushing mechanism 42 can adopt a cylinder or a motor as a power source, and the specific structure can be set according to the prior art, which is not limited to the drawings of the embodiment.

[0052] The specific feeding and conveying process of the conveying line 1 is as follows: a stamping line discharging robot (not shown in the figure) takes out a group of first side plates 101 and second side plates 102 from a press and feeds and places them into the conveying line 1 to abut against a group of positioning members; then the servo motor of the conveying line 1 drives the conveying line 1 to forward convey one station, the stamping line discharging robot feeds for the second time, and the servo motor drives the conveying line 1 to forward convey one station for the second time; subsequently, the stamping line discharging robot feeds for the third time, at this time, the first group of first side plates 101 and second side plates 102 fed first have been conveyed to the jacking positioning assembly 4, and the jacking positioning assembly 4 acts to jack up the group of first side plates 101 and second side plates 102. The feeding and jacking are synchronized to improve the efficiency. The conveying line 1 is driven by a servo motor and uses a toothed synchronous belt to ensure accurate conveying distance. The conveying distance of the conveying line 1 each time is determined according to the spacing between the adjacent two groups of side plates and the size of each group of first side plates 101 and second side plates 102, which is not limited in the embodiment. The first group of side plates is taken away at the same time, and the third group of side plates is placed on the feeding position of the conveying line 1; then the second group of side plates is conveyed to the feeding position of the jacking positioning assembly 4 to complete the jacking and positioning conversion, and the fourth group of side plates is placed on the feeding position, and so on.

[0053] The grabbing assembly 2 includes a row frame mechanism 21 and a mechanical hand 22. The mechanical hand 22 is movably arranged on the row frame mechanism 21. The mechanical hand 22 can move back and forth between the jacking positioning assembly 4 and the overturning assembly 3. The mechanical hand 22 can simultaneously grab the first side plate 101 and the second side plate 102, and place the first side plate 101 and the second side plate 102 jacked and repositioned by the jacking positioning assembly 4 on the two overturning mechanisms 31 of the overturning assembly 3. The mechanical hand 22 moves to the jacking positioning assembly 4 again after completing the grabbing and placing once to prepare for the next grabbing.

[0054] The grabbing end of the manipulator 22 is provided with two groups of sponge suction cups 221, which respectively adsorb the upper surfaces of the first side plate 101 and the second side plate 102. The grabbing mode of the suction cups is relatively simple, and the sponge suction cups 221 with sponge pieces can avoid scratching the upper surfaces of the first side plate 101 and the second side plate 102. The distance between the two groups of sponge suction cups 221 can be adjusted and set according to the width dimension of the side plate, meeting the adsorption needs of different models of side plates. Even if the width dimension changes due to the change of the side plate model, the two groups of sponge suction cups 221 can still adsorb the upper surfaces of the first side plate 101 and the second side plate 102 at the same time. In this way, the manipulator 22 will not change the relative positions of the outer folding edges 1002 of the first side plate 101 and the second side plate 102 during the grabbing and moving process, ensuring the accuracy of the outer folding edges 1002 as the positioning reference. As shown in Figure 7 , the figure shows the positions of a plurality of different models of the first side plate 101 and the second side plate 102 relative to the sponge suction cups 221.

[0055] In order to ensure that the positions of the outer folding edges 1002 and the outer side surfaces that have been adjusted as the positioning reference do not change during the flipping process, the rotation axis of the flipping mechanism 31 is arranged in line with the flipping folding line 1003 of the outer folding edge 1002. The flipping folding line 1003 is the connection between the outer folding edge 1002 and the outer side surface, as shown in Figure 9 ; taking the flipping folding line 1003 as the rotation axis of the flipping mechanism 31, so that the flipped outer folding edge 1002 and the outer side surface only change the angle relative to the horizontal plane, and do not move, ensuring the accuracy of the outer folding edge 1002 and the outer side surface as the positioning reference.

[0056] In order to make the side plate form the outer side surface as the positioning reference on the flipping mechanism 31, the flipping assembly 3 further comprises a first positioning mechanism 32, and the first positioning mechanism 32 comprises a third positioning piece, which abuts against the inner side surface of the side plate to position the height of the side plate in the vertical direction. The third positioning piece is four profiled positioning blocks, which better fit the inner side surface of the side plate, and are respectively located at the four corners of the side plate, thereby ensuring the position accuracy of the outer side surface. The profile of the profiled positioning block can be adjusted according to the appearance of the side plate, which is not limited to the present embodiment.

[0057] Of course, in addition to positioning the outer side surface of the side plate in the height direction on the flipping mechanism 31, the side plate also needs to be positioned in the width direction and the length direction. The flipping assembly 3 further comprises a second positioning mechanism 34 and a third positioning mechanism 35, the second positioning mechanism 34 is used to constrain the position of the side plate in the width direction of the side plate, and the third positioning mechanism 35 is used to constrain the position of the side plate in the length direction of the side plate. In this way, the side plate is completely constrained in the X, Y and Z directions on the flipping mechanism 31.

[0058] Specifically, the second positioning mechanism 34 includes an outer positioning block 341 and an outer clamping cylinder 342; when the mechanical arm 22 places the side plate on the turnover mechanism 31, the outer flange 1002 abuts against the outer positioning block 341, and the outer flange 1002 is clamped between the outer positioning block 341 and the piston rod of the outer clamping cylinder 342 through the action of the outer clamping cylinder 342, thereby achieving the positioning of the side plate in the width direction. The second positioning mechanism 34 has two outer positioning blocks 341 arranged at intervals to ensure a larger positioning area and higher positioning accuracy.

[0059] Similarly, the third positioning mechanism 35 includes a side positioning block 351 and a side clamping cylinder 352, and the side clamping cylinder 352 pushes the side plate to abut against the side positioning block 351, thereby achieving the positioning of the side plate in the length direction. The third positioning mechanism 35 has two side positioning blocks 351 arranged at intervals to ensure a larger positioning area and higher positioning accuracy.

[0060] The turnover assembly 3 further includes a positioning suction cup 33 for adsorbing the inner side of the side plate. After the height position of the outer side is adjusted, and the side plate is completely constrained in the X, Y, and Z directions on the turnover mechanism 31 through the second positioning mechanism 34 and the third positioning mechanism 35, in order to avoid displacement of the side plate during the turnover process, the positioning suction cup 33 can tightly adsorb the inner side of the side plate. Figure 8 A structural schematic view of a set of turnover mechanisms 31 with the first positioning mechanism 32, the positioning suction cup 33, the second positioning mechanism 34, and the third positioning mechanism 35 is shown in FIG. 6, which is used for turnover and secondary positioning of one of the first side plate 101 and the second side plate 102; another set of symmetrical turnover mechanisms 31 (refer to FIG. 7) is used for turnover and secondary positioning of the other of the first side plate 101 and the second side plate 102, and the specific structure is not described again. Figure 1 ) for turnover and secondary positioning of the other of the first side plate 101 and the second side plate 102, and the specific structure is not described again.

[0061] As shown in FIG. 6, Figure 10 The turnover assembly 3 further includes a turnover table 371 for carrying the side plate, a turnover cylinder 36, and a horizontal limiting mechanism 38. The mechanical arm 22 moves and carries the side plate to the turnover table 371, and the turnover cylinder 36 drives the turnover table 371 to turn on the turnover table support 372. In the initial state, the turnover table 371 is horizontally arranged, and waits for the mechanical arm 22 to move and carry the side plate. The horizontal limiting mechanism 38 is used for abutting and limiting to constrain the turnover table 371 to be in the horizontal state. The horizontal limiting mechanism 38 includes a first horizontal limiting block 381 arranged on the turnover table support 372, and a second horizontal limiting block 382 arranged on the turnover table 371, which turns with the turnover table 371; when the second horizontal limiting block 382 abuts against the first horizontal limiting block 381, it indicates that the turnover table 371 is in the completely horizontal state, thereby ensuring the levelness of the side plate.

[0062] Similarly, asFigure 11 As shown, the overturning assembly 3 further comprises a vertical limiting mechanism 39 for abutting limiting to constrain the overturning table 371 to be in a vertical state. The vertical limiting mechanism 39 comprises a first vertical limiting block 391 arranged on the overturning table support 372, and a second vertical limiting block 392 arranged on the overturning table 371 and overturning with the overturning table 371. When the second vertical limiting block 392 abuts against the first vertical limiting block 391, it indicates that the overturning table 371 is in a completely vertical state, thereby ensuring the perpendicularity of the side plate.

[0063] The multi-model side plate loading and positioning conversion equipment provided by the embodiment further comprises a base assembly 5, and the two sets of overturning mechanisms 31 are movably arranged on the base assembly 5. The two sets of overturning mechanisms 31 can move away from each other or move towards each other. When the two sets of overturning mechanisms 31 move away from each other, the distance between the two side plates in the vertical state can be adjusted to adapt to the adjustment of the distance between the two side plates by the box shell of different sizes. The base assembly 5 is provided with two sets of centering cylinders 51. As shown in the figure, the two sets of centering cylinders 51 act simultaneously to push the two sets of overturning mechanisms 31 to adjust the horizontal distance between the two side plates, so as to ensure the accuracy of the distance between the two side plates of the same box shell and keep consistent with the width of the box shell. Figure 12 As shown, the two sets of centering cylinders 51 act simultaneously to push the two sets of overturning mechanisms 31 to adjust the horizontal distance between the two side plates, so as to ensure the accuracy of the distance between the two side plates of the same box shell and keep consistent with the width of the box shell.

[0064] After the two side plates are overturned and the positioning reference is adjusted, the mechanical arm of the next station grasps the two side plates, and then, after the side plates are taken away, the base assembly 5 returns the two sets of overturning mechanisms 31 to the initial position, and the two sets of overturning mechanisms 31 are overturned in the reverse direction to wait for the next set of first side plate 101 and second side plate 102 moved by the mechanical hand 22.

[0065] Specifically, each set of centering cylinder 51 of the base assembly 5 is provided with a corresponding first centering limiting block 521 and a second centering limiting block 522, and the first centering limiting block 521 and the second centering limiting block 522 are oppositely arranged to limit the horizontal movement distance of the overturning mechanism 31 on the base assembly 5. When the overturning mechanism 31 receives the horizontally arranged side plate moved by the mechanical hand 22, the overturning mechanism 31 abuts against the first centering limiting block 521 on the outside, and the distance between the two sets of overturning mechanisms 31 is large to adapt to the distance between the two side plates adjusted by the jacking and positioning assembly 4 to position the outer folding edge 1002. After the two sets of overturning mechanisms 31 overturn the two side plates, the two sets of centering cylinders 51 act simultaneously to push the two sets of overturning mechanisms 31, so that the overturning mechanism 31 abuts against the second centering limiting block 522. The two sets of centering cylinders 51 act towards each other to center the two sets of overturning mechanisms 31, and the mechanical hard limiting of the second centering limiting block 522 is used to ensure the accuracy of the distance between the two side plates of the same box shell.
