Description

Technical Field

[0001] The present application belongs to the technical field of load-bearing devices, and specifically relates to a load-bearing tray and an assembly system. Background Art

[0002] In an assembly system, for example, on an automated assembly line for a new energy vehicle power source, the assembly operation requires a carrier tray to run the turnover product. New energy power source structural parts of different sizes have different positions and supports on the carrier tray due to their different appearances and structures. In order to save costs, multiple structural parts usually share one carrier tray. In the related art, the positioning column of the carrier tray is an upright positioning column that cannot be bent, and the upright positioning column is often fixed to the carrier tray with screws. For example, the positioning column on the carrier tray that matches the first structural part is relatively high, and the higher positioning column is easy to interfere with the second structural part, resulting in the second structural part being unable to be placed on the carrier tray. Therefore, the higher positioning column needs to be disassembled before the second structural part can be placed on the carrier tray. If the first structural part needs to be placed later, the positioning column of the first structural part needs to be reinstalled on the carrier tray before it can be used. Therefore, when the carrier tray carries structural parts of different sizes, it is usually necessary to disassemble or reinstall the positioning column, which costs a lot of labor and time, and reduces production efficiency. Utility Model Content

[0003] In view of this, the first aspect of the present application provides a carrying tray, which is applied to an assembly system, wherein the assembly system includes a first structural member and a second structural member of different sizes, and the carrying tray is used to carry the first structural member or the second structural member; the carrying tray includes a base plate, and a first positioning column rotatably connected to the base plate, the first positioning column having an upright state for fixing the first structural member to the carrying tray, and a bent state for avoiding the second structural member placed on the carrying tray, and the first positioning column can rotate relative to the base plate to switch between the upright state and the bent state.

[0004] The first positioning column of the carrier tray provided in the first aspect of the present application has an upright state and a bent state. When the carrier tray is used to carry the first structural member, the first positioning column stands upright on the substrate, which can also be understood as the first positioning column being perpendicular to the substrate, so as to facilitate positioning and fixing the first structural member on the first positioning column. When the carrier tray is used to carry the second structural member, the first positioning column is bent relative to the substrate, which can also be understood as the angle between the first positioning column and the substrate is an acute angle, or the first positioning column is parallel to the substrate, so as to facilitate the first positioning column to avoid the second structural member so that the second structural member can be firmly placed on the carrier tray.

[0005] Moreover, in the related art, since the positioning column needs to be frequently disassembled, the screw holes on the carrier tray are easily worn and the threads are loose, which makes the positioning column unstable and easy to loosen, thereby reducing the positioning effect on the structural member. However, since the first positioning column provided in the present application can rotate relative to the base plate to switch between the upright state and the bent state without disassembly, it will not cause the screw holes on the carrier tray to wear, and can ensure that the first positioning column is firmly fixed to the base plate, thereby improving the reliability of the carrier tray.

[0006] Therefore, the supporting tray of the present application is provided with a first positioning column that can rotate relative to the base plate, that is, the first positioning column can be bent relative to the base plate, thereby achieving the avoidance of the second structural member without removing the first positioning column, and there is no need to reinstall the first positioning column to fix the first structural member, thereby reducing labor costs, reducing production time, and improving production efficiency.

[0007] Wherein, the first positioning column comprises a bending seat fixed to the substrate, a bending column rotatably connected to the bending seat, and a bending shaft passing through the bending seat and the bending column, and the bending column can rotate relative to the bending seat;

[0008] Among them, when the first positioning column is in the upright state, the extension direction of the bending seat is parallel to the extension direction of the bending column; when the first positioning column is in the bent state, the extension direction of the bending seat is set at an angle to the extension direction of the bending column.

[0010] Among them, the surface of the connecting protrusion facing away from the substrate includes a limiting surface for abutting the bottom of the groove, and an avoidance surface inclined toward the direction close to the substrate, there is a gap between the avoidance surface and the bottom of the groove, and the limiting surface is bent to connect the avoidance surface.

[0011] Wherein, the carrying tray also includes a fixing sleeve mounted on the first positioning column, and the fixing sleeve can move relative to the bending column; wherein, when the first positioning column is in the upright state, the fixing sleeve is mounted on the bending seat and the bending column; when the first positioning column is in the bending state, the fixing sleeve is mounted on the end of the bending column away from the bending seat, or the fixing sleeve is mounted on the end of the bending seat away from the bending column.

[0012] Wherein, a limiting portion is provided on the peripheral side wall of the bending column, and the limiting portion is used to abut against the surface of the fixing sleeve away from the bending seat.

[0013] The carrying tray further comprises a second positioning column fixed to the base plate, the second positioning column and the first positioning column are arranged on the same side of the base plate and are spaced apart, and the second positioning column is used to fix the second structure to the carrying tray.

[0014] Among them, along the arrangement direction from the substrate to the first positioning pillars, the height of the first positioning pillars in the upright state is greater than the height of the second positioning pillars, and the height of the first positioning pillars in the bent state is less than the height of the second positioning pillars.

[0015] Wherein, the carrying tray meets at least one of the following conditions:

[0016] The carrying tray further includes a blocking portion, wherein the blocking portion and the first positioning column are disposed on the same side of the substrate, and the blocking portion is used to abut against the first structural member or the second structural member;

[0017] The carrying tray further includes a positioning portion, wherein the positioning portion and the first positioning column are disposed on two opposite sides of the substrate, and the positioning portion is used to fix the substrate.

[0018] A second aspect of the present application provides an assembly system, which includes a first structural member and a second structural member of different sizes, and a carrying tray as provided in the first aspect of the present application, wherein the carrying tray is used to carry the first structural member or the second structural member.

[0019] The assembly system provided in the second aspect of the present application adopts the supporting tray provided in the first aspect of the present application. The supporting tray utilizes a first positioning column that can rotate relative to the substrate, that is, the first positioning column can be bent relative to the substrate, thereby achieving the avoidance of the second structural member without removing the first positioning column, and there is no need to reinstall the first positioning column to fix the first structural member, thereby reducing labor costs, reducing production time, and improving production efficiency.

[0040] The present embodiment provides a carrier tray 1, which is applied to an assembly system, wherein the assembly system includes a first structural member 21 and a second structural member 22 of different sizes, and the carrier tray 1 is used to carry the first structural member 21 or the second structural member 22; the carrier tray 1 includes a base plate 11, and a first positioning column 12 rotatably connected to the base plate 11, the first positioning column 12 has an upright state for fixing the first structural member 21 to the carrier tray 1, and a bent state for avoiding the second structural member 22 placed on the carrier tray 1, and the first positioning column 12 can rotate relative to the base plate 11 to switch between the upright state and the bent state.

[0041] The carrier tray 1 provided in this embodiment includes a substrate 11 and a first positioning column 12. The substrate 11 is used to carry other components. The first positioning column 12 is used to fix the first structural member 21 and plays a positioning role on the first structural member 21. The substrate 11 is rotatably connected to the first positioning column 12. For example, part of the first positioning column 12 is fixed to the substrate 11, and another part of the first positioning column 12 can rotate relative to the substrate 11. Specifically, part of the first positioning column 12 is fixed to the substrate 11 with screws. For another example, the first positioning column 12 can rotate relative to the substrate 11 as a whole. The number of the first positioning columns 12 is one or more, for example, the number of the first positioning columns 12 is 4.

[0042] The assembly system includes a first structural member 21 and a second structural member 22 of different sizes. Optionally, the height of the first structural member 21 is greater than or less than the height of the second structural member 22. Optionally, the width of the first structural member 21 is greater than or less than the width of the second structural member 22. Optionally, the length of the first structural member 21 is greater than or less than the length of the second structural member 22.

[0043] Optionally, there are multiple first positioning posts 12, and the multiple first positioning posts 12 are arranged on the substrate 11 at intervals along the circumferential direction of the substrate 11. Optionally, the multiple first positioning posts 12 are arranged on the same side of the substrate 11. Optionally, the distance between two adjacent first positioning posts 12 is equal. Optionally, the first positioning posts 12 are rotated toward the outside of the carrying tray 1, so that the first positioning posts 12 are switched from an upright state to a bent state.

[0044] Optionally, the surface of the first positioning column 12 away from the substrate 11 has a first positioning protrusion, and the first structural member 21 has a first positioning hole. When the first positioning column 12 fixes the first structural member 21, at least part of the first positioning protrusion is disposed in the first positioning hole.

[0045] Specifically, the first positioning column 12 has an upright state (eg Figure 1 as shown) and the bending state (as shown Figure 2When the carrying tray 1 is used to carry the first structural member 21, the first positioning column 12 stands upright on the substrate 11, which can also be understood as the first positioning column 12 being perpendicular to the substrate 11, so as to facilitate positioning and fixing the first structural member 21 on the first positioning column 12. When the carrying tray 1 is used to carry the second structural member 22, the first positioning column 12 is bent relative to the substrate 11, which can also be understood as the angle between the first positioning column 12 and the substrate 11 is an acute angle, or the first positioning column 12 is parallel to the substrate 11, so as to facilitate the first positioning column 12 to avoid the second structural member 22, so that the second structural member 22 can be firmly placed on the carrying tray 1.

[0046] Furthermore, in the related art, since the positioning posts need to be frequently disassembled, the screw holes on the carrier tray 1 are easily worn and the threads are loose, resulting in the positioning posts being unstable and easily loosened, thereby reducing the positioning effect on the structural parts. However, since the first positioning posts 12 provided in this embodiment can rotate relative to the base plate 11 to switch between the upright state and the bent state without disassembly, the screw holes on the carrier tray 1 will not be worn, and the first positioning posts 12 can be firmly fixed to the base plate 11, thereby improving the reliability of the carrier tray 1.

[0047] For example, Figure 3 As shown, when the first structural member 21 needs to be placed, the first positioning column 12 is placed in an upright state, the first positioning hole of the first structural member 21 is aligned with the first positioning protrusion of the first positioning column 12, and the first structural member 21 is placed on the first positioning column 12. Figure 4 As shown, when the second structural member 22 needs to be placed, the first positioning column 12 is bent, the second positioning hole of the second structural member 22 is aligned with the second positioning protrusion of the second positioning column 14 , and the second structural member 22 is placed on the second positioning column 14 .

[0048] Therefore, the carrying tray 1 of this embodiment is provided with a first positioning column 12 that can rotate relative to the base plate 11, that is, the first positioning column 12 can be bent relative to the base plate 11, thereby achieving the avoidance of the second structural member 22 without removing the first positioning column 12, and there is no need to reinstall the first positioning column 12 to fix the first structural member 21, thereby reducing labor costs, reducing production time, and improving production efficiency.

[0049] Please refer to Figure 1-Figure 10 , Figure 5 A three-dimensional structural diagram of a first positioning column and a fixing sleeve provided in one embodiment of the present application. Figure 6 This is a three-dimensional structural diagram of a first positioning column and a fixing sleeve provided in another embodiment of the present application.

[0050] In one embodiment, the first positioning column 12 includes a bending seat 121 fixed to the substrate 11, a bending column 122 rotatably connected to the bending seat 121, and a bending shaft 123 passing through the bending seat 121 and the bending column 122, and the bending column 122 can rotate relative to the bending seat 121.

[0051] Among them, when the first positioning column 12 is in the upright state, the extension direction of the bending seat 121 is parallel to the extension direction of the bending column 122; when the first positioning column 12 is in the bent state, the extension direction of the bending seat 121 is set at an angle to the extension direction of the bending column 122.

[0052] The first positioning column 12 provided in this embodiment includes a bending seat 121, a bending column 122, and a bending shaft 123. One end of the bending seat 121 is fixed on the substrate 11, and the other end is rotatably connected to the bending column 122 through the bending shaft 123. Optionally, the bending seat 121 is fixed to the substrate 11 by screws. The bending shaft 123 penetrates one end of the bending seat 121 away from the substrate 11, and also penetrates one end of the bending column 122 close to the bending seat 121.

[0053] like Figure 7 and Figure 8 As shown, when the first positioning column 12 is in an upright state, the extension direction of the bending seat 121 is parallel to the extension direction of the bending column 122. At this time, the bending seat 121 is perpendicular to the substrate 11, and the bending column 122 is also perpendicular to the substrate 11. Fig. 9 and Fig.10 As shown, when the first positioning column 12 is in a bending state, the extension direction of the bending seat 121 is set at an angle to the extension direction of the bending column 122, and the angle between the extension direction of the bending seat 121 and the extension direction of the bending column 122 is greater than 0° and less than 180°. At this time, the bending seat 121 is perpendicular to the substrate 11, and the angle between the bending column 122 and the substrate 11 is an acute angle, or the bending column 122 is parallel to the substrate 11.

[0054] In this embodiment, the first positioning column 12 is composed of a bending seat 121, a bending column 122, and a bending shaft 123. The bending seat 121 is fixed on the base plate 11, which can ensure that the first positioning column 12 is firmly fixed to the base plate 11, thereby improving the reliability of the carrying tray 1; the bending column 122 can rotate relative to the bending seat 121, that is, the bending column 122 can rotate relative to the base plate 11, thereby achieving the avoidance of the second structural member 22 without disassembling the first positioning column 12, and there is no need to reinstall the first positioning column 12 to fix the first structural member 21, thereby reducing labor costs, reducing production time, and improving production efficiency.

[0055] Please refer to Figure 1-Figure 10 In one embodiment, the bending seat 121 has a connecting protrusion 1211 arranged away from the substrate 11, and the bending column 122 is provided with a groove 1221 on the side close to the bending seat 121, the connecting protrusion 1211 is arranged in the groove 1221, and the bending axis 123 passes through the connecting protrusion 1211 and the groove wall of the groove 1221.

[0056] The bending seat 121 has a connecting protrusion 1211, and the bending column 122 is provided with a groove 1221, and at least part of the connecting protrusion 1211 is arranged in the groove 1221. The bending shaft 123 penetrates the connecting protrusion 1211 and penetrates the groove wall of the groove 1221. Optionally, the bending shaft 123 also penetrates the peripheral side surface of the bending column 122.

[0057] In this embodiment, a connecting protrusion 1211 is provided on the bending seat 121 and a groove 1221 is provided on the bending column 122 so that the connecting protrusion 1211 and the groove 1221 cooperate with each other, thereby improving the connection performance between the bending seat 121 and the bending column 122 and improving the reliability of the first positioning column 12.

[0058] Please refer to Figure 1-Figure 10 In one embodiment, the surface of the connecting protrusion 1211 facing away from the substrate 11 includes a limiting surface 1212 for abutting the bottom of the groove 1221, and an avoidance surface 1213 inclined toward the direction close to the substrate 11, and there is a gap between the avoidance surface 1213 and the bottom of the groove 1221, and the limiting surface 1212 is bent to connect the avoidance surface 1213.

[0059] The surface of the connecting protrusion 1211 facing away from the substrate 11 includes a limiting surface 1212. Optionally, the limiting surface 1212 is parallel to the substrate 11. Specifically, when the first positioning column 12 is in an upright state, the limiting surface 1212 can abut against the bottom of the groove 1221 to support the bending column 122, and also prevent the bending column 122 from bending relative to the substrate 11, thereby reducing the probability of the first positioning column 12 accidentally switching from the upright state to the bent state.

[0060] The surface of the connecting protrusion 1211 facing away from the substrate 11 also includes an avoidance surface 1213. The avoidance surface 1213 is inclined compared to the limiting surface 1212, which can also be understood as the avoidance surface 1213 is inclined compared to the substrate 11, or in other words, a chamfer is provided on the connecting protrusion 1211. Specifically, since there is a gap between the avoidance surface 1213 and the groove 1221, when the first positioning column 12 is in the process of switching between the upright state and the bent state, the part of the bending seat 121 at the avoidance surface 1213 avoids the bending column 122, so that the bending column 122 will not interfere with the bending seat 121, and the bending column 122 can smoothly rotate relative to the bending seat 121.

[0061] Please refer to Figure 1-Figure 10 In one embodiment, the carrying tray 1 also includes a fixing sleeve 13 sleeved on the first positioning column 12, and the fixing sleeve 13 can move relative to the bending column 122; wherein, when the first positioning column 12 is in the upright state, the fixing sleeve 13 is sleeved on the bending seat 121 and the bending column 122; when the first positioning column 12 is in the bent state, the fixing sleeve 13 is sleeved on the end of the bending column 122 away from the bending seat 121, or the fixing sleeve 13 is sleeved on the end of the bending seat 121 away from the bending column 122.

[0062] The carrier tray 1 provided in this embodiment also includes a fixing sleeve 13 for fixing the first positioning column 12. The fixing sleeve 13 is sleeved on the first positioning column 12, and the fixing sleeve 13 can move relative to the bending seat 121. The fixing sleeve 13 can move up and down relative to the bending column 122. For example, by moving the fixing sleeve 13, the fixing sleeve 13 can be sleeved on the bending seat 121 and the bending column 122. For another example, by moving the fixing sleeve 13, the fixing sleeve 13 can be sleeved only on the bending column 122. For another example, by moving the fixing sleeve 13, the fixing sleeve 13 can be sleeved only on the bending seat 121. The fixing sleeve 13 is adapted to the shape of the first positioning column 12. Optionally, the first positioning column 12 and the fixing sleeve 13 are both cylindrical.

[0063] This embodiment improves the reliability of the first positioning column 12 being in an upright state by providing a fixing sleeve 13. Specifically, when the fixing sleeve 13 is sleeved on the bending seat 121 and the bending column 122, the bending seat 121 perpendicular to the substrate 11 makes the fixing sleeve 13 also perpendicular to the substrate 11, and then the bending column 122 is also kept vertical by the vertical fixing sleeve 13 and will not fall over. At this time, the first positioning column 12 is in an upright state, and the bending column 122 cannot rotate relative to the bending seat 121; it can also be understood that when the fixing sleeve 13 is placed on the bending seat 121, the end of the bending column 122 is sleeved by the fixing sleeve 13 and fixed on the bending seat 121, so that the bending column 122 remains perpendicular to the bottom plate.

[0064] When the fixing sleeve 13 is only mounted on the bending seat 121 or the bending column 122, the bending column 122 can rotate relative to the bending seat 121, so that the first positioning column 12 switches from an upright state to a bent state. When the fixing sleeve 13 is taken up to the head of the bending column 122 and leaves the bending seat 121, the end of the bending column 122 is not fixed by the fixing sleeve 13, and can be rotated and tilted toward the outer periphery of the carrying tray 1 on the bending seat 121, so that the bending column 122 tilts onto the substrate 11.

[0065] Please refer to Figure 1-Figure 10 In one embodiment, a limiting portion 1222 is provided on the peripheral side wall of the bending column 122 , and the limiting portion 1222 is used to abut against the surface of the fixing sleeve 13 away from the bending seat 121 .

[0066] The bending column 122 provided in this embodiment is further provided with a limiting portion 1222. Optionally, the limiting portion 1222 is arranged around the peripheral side wall of the bending column 122. Optionally, the bending column 122 and the limiting portion 1222 are an integral structural member. The limiting portion 1222 is arranged at the end of the bending column 122 away from the bending seat 121.

[0067] In this embodiment, a limiting portion 1222 is provided on the peripheral side wall of the bending column 122 so that the limiting portion 1222 can abut against the surface of the fixing sleeve 13 away from the bending seat 121 to prevent the fixing sleeve 13 from falling off the bending column 122, thereby improving the reliability of the carrying tray 1.

[0068] Please refer to Figure 1-Figure 10 In one embodiment, the carrying tray 1 further includes a second positioning column 14 fixed to the substrate 11, the second positioning column 14 and the first positioning column 12 are arranged on the same side of the substrate 11 and are spaced apart, and the second positioning column 14 is used to fix the second structural member 22 to the carrying tray 1.

[0069] The carrier tray 1 provided in this embodiment further includes a second positioning column 14, which is used to fix the second structural member 22 and plays a positioning role on the second structural member 22. The second positioning column 14 cannot rotate relative to the substrate 11. The second positioning column 14 is perpendicular to the substrate 11. Optionally, the second positioning column 14 is fixed to the substrate 11 by screws. Optionally, the number of the second positioning columns 14 is one or more, for example, the number of the second positioning columns 14 is 4. Optionally, a plurality of the second positioning columns 14 are arranged on the substrate 11 at intervals along the circumferential direction of the substrate 11.

[0070] Optionally, the height of the first positioning column 12 is greater than or less than the height of the second positioning column 14. Optionally, the second positioning column 14 has a second positioning protrusion on a surface away from the substrate 11, and the second structural member 22 has a second positioning hole, and when the second positioning column 14 fixes the second structural member 22, at least part of the second positioning protrusion is disposed in the second positioning hole.

[0071] In this embodiment, the second positioning column 14 spaced apart from the first positioning column 12 is provided so that the second positioning column 14 can match with the second structural member 22 for fixing the second structural member 22 , thereby improving the practicality of the carrying tray 1 .

[0073] This embodiment improves the reliability of the carrying tray 1 by limiting the height of the first positioning column 12 in the upright state to be greater than the height of the second positioning column 14, thereby avoiding the second positioning column 14 interfering with the first structural member 21 when the carrying tray 1 carries the first structural member 21; and this embodiment further limits the height of the first positioning column 12 in the bent state to be less than the height of the second positioning column 14, thereby avoiding the first positioning column 12 interfering with the second structural member 22 when the carrying tray 1 carries the second structural member 22, thereby further improving the reliability of the carrying tray 1.

[0074] Please refer to Figure 1-Figure 11 , Fig.11 A three-dimensional structural diagram of a carrier tray from another angle provided for one embodiment of the present application. In one embodiment, the carrier tray 1 satisfies at least one of the following conditions: the carrier tray 1 further includes a blocking portion 15, the blocking portion and the first positioning column 12 are disposed on the same side of the substrate 11, and the blocking portion 15 is used to abut against the first structural member 21 or the second structural member 22.

[0075] The blocking portion 15 may be a baffle. The blocking portion 15 is spaced apart from the first positioning column 12. In this embodiment, by adding the blocking portion 15 on the substrate 11, the blocking portion 15 can abut against the first structural member 21 or the second structural member 22, thereby preventing the first structural member 21 or the second structural member 22 from directly abutting against the substrate 11, playing a supporting role, thereby improving the reliability of the carrying tray 1.

[0076] And / or, the carrying tray 1 further includes a positioning portion 16 , the positioning portion 16 and the first positioning column 12 are disposed on two opposite sides of the substrate 11 , and the positioning portion 16 is used to fix the substrate 11 .

[0077] The positioning portion 16 may be a positioning pin. In this embodiment, the positioning portion 16 is provided on the other side of the base plate 11 so as to fix the carrying tray 1 at other places, thereby improving the reliability of the carrying tray 1 .

[0078] In summary, the carrier tray 1 of this embodiment can accommodate multiple structural parts of different shapes, saving the cost of manufacturing the carrier tray 1 and saving materials. In addition, the first positioning column 12 does not need to be disassembled, and only the fixing sleeve 13 needs to be moved up and down to switch the first positioning column 12 between the upright state and the bent state. The first structural part 21 can be positioned in the upright state, and the second structural part 22 can be avoided in the bent state. The structural parts on the assembly line can be switched quickly and conveniently, and the production can be changed quickly to improve production efficiency. In addition, the carrier tray 1 is easy to use, and there is no need for tools such as wrenches and screwdrivers to operate the first positioning column 12 of the carrier tray 1. The first positioning column 12 can be kept tilted and upright by simply taking up and taking down the fixing sleeve 13, which is easy to operate.
