In order to make the present invention clear, elements irrelevant to the description are omitted from the details of this specification.
[0076] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.
[0077] The first aspect of the present application discloses a rolling wheel, comprising a wheel core and a rolling ring, the rolling ring being sleeved on the wheel core, the wheel core comprising a first plate body, a mounting seat and a second plate body, the mounting seat being connected to the first plate body along a first direction, the second plate body being connected to the mounting seat along the first direction, the mounting seat having a protruding convex portion, the rolling ring having a concave portion, the shape of the concave portion matching the protrusion, the rolling ring being sleeved on the peripheral wall of the mounting seat, and the concave portion accommodating the protrusion, the diameters of the first plate body and the second plate body being larger than the inner diameter of the rolling ring.
[0078] The above-mentioned concave part matches and accommodates the convex part, which is conducive to the rolling ring and the mounting seat forming a snap-fit structure, thereby helping to reduce the possibility of the rolling ring rotating relative to the mounting seat. In addition, the diameter of the first plate body and the second plate body is larger than the inner diameter of the rolling ring, which is equivalent to the rolling ring being sandwiched between the first plate body and the second plate body, which is conducive to reducing the possibility of the rolling ring moving relative to the mounting seat in the first direction and the opposite direction. In this way, it is conducive to reducing the possibility of the rolling ring offset relative to the mounting seat, thereby helping to improve the yield rate of the workpiece after rolling with the rolling wheel.
[0079] The second aspect of the present application discloses a rolling module, comprising a base, an axle seat and the rolling wheel described in the first aspect of the present application, wherein the axle seat is connected to the base, the axle seat is provided with a mounting position, and the rolling wheel can be rotatably disposed at the mounting position.
[0080] In the above-mentioned rolling module, the rolling wheel described in the first aspect of the present application is adopted, which is helpful to reduce the possibility of the rolling ring being offset relative to the mounting seat, thereby helping to improve the yield of the workpiece after rolling by the rolling module.
[0081] Some embodiments of the present application will be described below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.
[0082] See also Figure 1 The present application provides a rolling wheel 10 , which includes a wheel core 110 and a rolling ring 120 , wherein the rolling ring 120 is sleeved on the wheel core 110 .
[0083] In some embodiments, see Figure 1 The wheel core 110 includes a first plate 1110, a mounting seat 1120 and a second plate 1130. The mounting seat 1120 is connected to the second plate 1130 along a first direction D1. The first plate 1110 is connected to the mounting seat 1120 along a first direction D1. The diameters of the first plate 1110 and the second plate 1130 are greater than the inner diameter of the rolling ring 120.
[0084] In some embodiments, the wheel core 110 is made of a rigid material, such as metal, and the rolling ring 120 is made of an elastic material, such as rubber. It is understood that in other embodiments, the materials of the wheel core 110 and the rolling ring 120 can be set according to actual needs and are not limited here.
[0085] In some embodiments, the mounting base 1120 and the first plate 1110 are integrally formed. In some embodiments, the mounting base 1120 is welded to the first plate 1110. It is understood that in other embodiments, the connection between the mounting base 1120 and the first plate 1110 can be a detachable connection, which is not limited here.
[0086] See also Figure 1 , along the direction from the center of the mounting seat 1120 to the peripheral wall of the mounting seat 1120, the mounting seat 1120 has a protruding convex portion 1121, the rolling ring 120 has a concave portion 1210, the shape of the concave portion 1210 matches the convex portion 1121, the rolling ring 120 is sleeved on the peripheral wall of the mounting seat 1120, and the concave portion 1210 accommodates the convex portion 1121. In this way, the concave portion 1210 matches and accommodates the convex portion 1121, which is conducive to the rolling ring 120 and the mounting seat 1120 forming a snap-fit structure, thereby facilitating the reduction of the possibility of the rolling ring 120 rotating relative to the mounting seat 1120. The diameters of the first plate body 1110 and the second plate body 1130 are larger than the inner diameter of the rolling ring 120, which is equivalent to the rolling ring 120 being sandwiched between the first plate body 1110 and the second plate body 1130, which is conducive to reducing the possibility of the rolling ring 120 moving relative to the mounting seat 1120 along the first direction D1 and the reverse direction thereof.
[0087] In some embodiments, the first direction D1 refers to a direction from the center of the first plate 1110 to the center of the mounting seat 1120 .
[0088] In some embodiments, the direction from the center of the mounting seat 1120 to the peripheral wall of the mounting seat 1120 refers to the radial direction of the mounting seat 1120.
[0089] See also Figure 1In the present embodiment, the number of the protrusions 1121 is three, and the three protrusions 1121 are evenly distributed on the peripheral wall of the mounting seat 1120. The even distribution of the three protrusions 1121 means that the angles between two adjacent protrusions 1121 are consistent. In this way, by arranging a suitable number of protrusions 1121, it is beneficial for the rolling ring 120 and the mounting seat 1120 to form a snap-fit structure in multiple directions, which is beneficial for further reducing the possibility of the rolling ring 120 offset relative to the mounting seat 1120. It can be understood that in other embodiments, the number of protrusions 1121 is at least two, for example, the number of protrusions 1121 is two, three, four, five or more, and in some embodiments, the angle between at least two protrusions 1121 may also be unevenly distributed, and the present application does not limit this.
[0090] In some embodiments, see Figure 1 The second plate 1130 can be detachably fixed to the mounting seat 1120. In this way, if the rolling wheel 10 is used for a long time and the rolling ring 120 is worn, the second plate 1130 can be disassembled from the mounting seat 1120 to facilitate the replacement of the rolling ring 120.
[0091] In some embodiments, see Figure 1 The mounting seat 1120 is provided with a fixing hole 1122, and the second plate 1130 is fixed to the mounting seat 1120 by means of a fastener 1140 and the fixing hole 1122. In this way, since the second plate 1130 is detachable relative to the mounting seat 1120, the fixing method of the fastener 1140 and the fixing hole 1122 is helpful to improve the stability of the fixing of the second plate 1130 and the mounting seat 1120. In the present application, the second plate 1130 is fixed to the mounting seat 1120 by means of a fastener 1140 and the fixing hole 1122, which means that the fastener 1140 passes through the second plate 1130 and is fastened to the fixing hole 1122, thereby fixing the second plate 1130 to the mounting seat 1120.
[0092] In some embodiments, the fixing hole 1122 is close to the protrusion 1121 of the mounting seat 1120. In this way, it is beneficial to fix the second plate 1130 along the peripheral wall of the mounting seat 1120, thereby facilitating the reduction of the deviation of the second plate 1130 caused by resisting the deformation of the rolling ring 120.
[0093] In some embodiments, see Figure 2The wheel core 110 further includes a first mounting shaft 1150 and a second mounting shaft 1160. The first mounting shaft 1150 protrudes from the first plate body 1110 in the opposite direction of the first direction D1, and the second mounting shaft 1160 protrudes from the second plate body 1130 in the first direction D1. Thus, the first mounting shaft 1150 and the second mounting shaft 1160 facilitate the installation of the rolling wheel 10 on other components for use, which facilitates a smoother rolling process.
[0094] Please refer to Figure 3 and Figure 4 The rolling module 1 includes a base 20, a wheel axle seat 30, a mounting position 40 and a rolling wheel 10. The wheel axle seat 30 is connected to the base 20, and the wheel axle seat 30 is provided with a mounting position 40. The rolling wheel 10 can be rotatably arranged at the mounting position 40. In this way, it is helpful to reduce the possibility of the rolling ring 120 being offset relative to the mounting seat 1120, thereby helping to improve the rolling of the workpiece 2 by the rolling module 1 (see Figure 6 ) after.
[0095] In some embodiments, please refer to Figure 3 and Figure 4 The rolling module 1 further includes a rotating member 50, which is disposed on the base 20. The rotating member 50 is connected to the axle seat 30 to drive the axle seat 30 to rotate. In this way, the rolling direction of the rolling wheel 10 can be changed by driving the axle seat 30 to rotate through the rotating member 50, thereby facilitating the rolling wheel 10 to roll the workpiece 2 from multiple directions.
[0096] In some embodiments, see Figure 3 The rotation plane P1 of the axle seat 30 and the rolling plane P2 of the rolling wheel 10 have an included angle. For example, the included angle between the rotation plane P1 of the axle seat 30 and the rolling plane P2 of the rolling wheel 10 is 90 degrees.
[0097] In some embodiments, the axle seat 30 is indirectly connected to the base 20 by being connected to the rotating member 50 .
[0098] In some embodiments, please refer to Figure 3 and Figure 4 The base 20 includes a first base 210, and the first base 210 is used to connect the motion mechanism (not shown) that drives the rolling module 1 to make the rolling wheel 10 roll. The base 20 also includes a second base 220, and the second base 220 cooperates with the first base 210 to support the rotating member 50. In some embodiments, the rotating member 50 is disposed between the first base 210 and the second base 220. In this way, it is convenient to fix the rotating member 50.
[0099] In some embodiments, see Figure 3 and Figure 4The base 20 further includes a rod body 230 , which connects the first base 210 and the second base 220 .
[0100] In some embodiments, the rotating member 50 is a rotary cylinder, which is connected to a pneumatic source.
[0101] In some embodiments, please refer to Figure 3 and Figure 4 The axle seat 30 includes a mounting groove 310, and the mounting position 40 is detachably arranged in the mounting groove 310. In this way, it is beneficial to improve the convenience of repairing or replacing the mounting position 40.
[0102] In some embodiments, see Figure 4 The rolling module 1 further includes a connecting member 60 , which is used to connect the rotating member 50 and the axle seat 30 .
[0103] In some embodiments, see Figure 4 The connecting member 60 includes a first hole 610 and a second hole 620. The first hole 610 is used to connect the connecting member 60 to the rotating member 50, and the second hole 620 is used to connect the connecting member 60 to the axle seat 30. In some embodiments, the hole depth direction of the first hole 610 is orthogonal to the hole depth direction of the second hole 620.
[0104] In some embodiments, see Figure 5 The mounting position 40 includes a bottom plate 410 and two side plates 420. The two side plates 420 are fixed to the same surface of the bottom plate 410. The bottom plate 410 has a slot 430 for providing a rolling space for the rolling wheel 10. The rolling wheel 10 is mounted between the two side plates 420, and the bottom of the rolling wheel 10 passes through the slot 430. In this way, the two side plates 420 of the mounting position 40 are conducive to limiting the rolling wheel 10 from generating undesired movement during the rolling process, thereby facilitating the accuracy of rolling the position to be rolled.
[0105] In some embodiments, bearings are respectively provided on the two side plates 420, and the first mounting shaft 1150 and the second mounting shaft 1160 of the rolling wheel 10 are respectively mounted on the bearings of the two side plates 420. In this way, the rolling wheel 10 is facilitated to roll.
[0106] In some embodiments, see Figure 6The installation position 40 includes a first position 401, a second position 402, a third position 403 and a fourth position 404 which are sequentially arranged on the axle seat 30. The distance between the bottom of the rolling wheel 10 arranged at the first position 401 and the fourth position 404 and the axle seat 30 is the first distance h1, and the distance between the bottom of the rolling wheel 10 arranged at the second position 402 and the third position 403 and the axle seat 30 is the second distance h2, and the first distance h1 is greater than the second distance h2. In other words, the bottom of the rolling wheel 10 arranged at the first position 401 and the fourth position 404 is farther away from the axle seat 30 than the rolling wheel 10 arranged at the second position 402 and the third position 403. In this way, when the rolling wheels 10 disposed at the first setting position 401 and the fourth setting position 404 are used for rolling, it is helpful to reduce the situation where the rolling wheels 10 disposed at the second setting position 402 and the third setting position 403 cause undesired rolling on the workpiece 2 .
[0107] In some embodiments, the outer diameters of the rolling wheels 10 arranged at the first position 401 and the fourth position 404 and the rolling wheels 10 arranged at the second position 402 and the third position 403 are equal, and the central axes of the rolling wheels 10 at the first position 401 and the fourth position 404 are farther away from the base 20 than the central axes of the rolling wheels 10 at the second position 402 and the third position 403.
[0108] In some embodiments, the outer diameter of the rolling wheel 10 set at the first position 401 and the fourth position 404 is larger than the outer diameter of the rolling wheel 10 set at the second position 402 and the third position 403, and the central axis of the rolling wheel 10 at the first position 401 and the fourth position 404 is in the same straight line as the central axis of the rolling wheel 10 at the second position 402 and the third position 403.
[0109] It can be understood that the number and position of the rolling wheels 10, the mounting positions 40, and the mounting grooves 310 can be set according to actual needs and are not limited here.
[0110] The working process of the rolling module 1 of the present application is as follows: the workpiece 2 enters the corresponding workstation, and after the rolling module 1 moves to the position where the workpiece 2 is to be rolled, it gradually approaches the workpiece 2 until the rolling wheels 10 set at the second position 402 and the third position 403 can contact the workpiece 2, and the rolling module 1 performs at least one reciprocating motion along the length direction of the workpiece 2. In this way, the long side of the workpiece 2 is rolled. Then the rolling module 1 returns to the position where the workpiece 2 is to be rolled, and after the rotating member 50 drives the wheel axle seat 30 to rotate a certain angle (for example, 90 degrees), the rolling module 1 gradually approaches the workpiece 2 until the rolling wheels 10 set at the first position 401 and the fourth position 404 can contact the workpiece 2, and perform at least one reciprocating motion along the width direction of the workpiece 2. In this way, the short side of the workpiece 2 is rolled. It is not difficult to understand that the short side of the workpiece 2 can also be rolled first, and then the long side of the workpiece 2 can be rolled.
[0111] In the above-mentioned rolling wheel 10 and rolling module 1, the concave portion 1210 matches and accommodates the convex portion 1121, which is conducive to the rolling ring 120 and the mounting seat 1120 forming a snap-fit structure, thereby helping to reduce the possibility of the rolling ring 120 rotating relative to the mounting seat 1120. In addition, the diameter of the first plate 1110 and the second plate 1130 is larger than the inner diameter of the rolling ring 120, which is equivalent to the rolling ring 120 being sandwiched between the first plate 1110 and the second plate 1130, which is conducive to reducing the possibility of the rolling ring 120 moving relative to the mounting seat 1120 along the first direction D1 and its reverse direction. In this way, it is conducive to reducing the possibility of the rolling ring 120 offsetting relative to the mounting seat 1120, thereby helping to improve the yield of the workpiece 2 after rolling using the rolling wheel 10 and the rolling module 1.
[0112] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application, and are not intended to limit the present application. As long as they are within the essential scope of the present application, appropriate changes and modifications to the above embodiments are within the scope disclosed in the present application.
