Description

TECHNICAL FIELD

[0001] The utility model relates to material transportation technical field, concretely relates to a turnover box for stirring frame. BACKGROUND

[0002] The turnover box is also called a logistics box, and is suitable for transportation, distribution, storage, circulation processing and other links in factory logistics.

[0003] The turnover box generally comprises a bottom wall and a peripheral wall, and for a turnover box for slender parts, a plurality of interval protrusions protruding from the bottom wall and spaced apart in a straight line direction are generally arranged in the box, a long-shaped placement position capable of accommodating the slender parts is formed between adjacent interval protrusions and between the interval protrusions and the peripheral wall, the slender parts placed in the long-shaped placement position are separated, which is beneficial to protection, and after turnover transportation, the parts are still in the placement position, facilitating subsequent part taking.

[0004] It is hoped that the turnover box for stirring frame can be more accurately positioned in cooperation with the structure of the stirring frame, so as to facilitate automatic feeding and automatic assembly and other processes in cooperation with automatic equipment. However, the existing stirring frame generally adopts manual feeding and manual assembly into the powder bin, and the turnover box, such as the existing turnover box for slender parts, only has a simple position separation function, and cannot meet the cooperation requirements of automatic feeding and automatic assembly of the stirring frame. UTILITY MODEL CONTENTS

[0005] The utility model aims to provide a turnover box for stirring frame, which can meet the positioning requirements of the stirring frame based on the cooperation requirements of automatic feeding and automatic assembly.

[0006] The turnover box for stirring frame provided by the utility model comprises a bottom wall, a peripheral wall and interval protrusions, the peripheral wall is connected to the outer peripheral edge of the bottom wall and extends upward, and the interval protrusions are arranged on the upper side of the bottom wall; the turnover box for stirring frame is provided with positioning structure groups, each positioning structure group is used for cooperating with one stirring frame, the positioning structure group comprises a supporting part, a plug-in position, a first limiting position and a second limiting position; the top surface of the interval protrusion serves as part of the supporting part; along a first extension direction of the bottom wall, a plug-in position entering downward is formed between two adjacent interval protrusions; the peripheral wall comprises a first side wall and a second side wall oppositely arranged along a second extension direction of the bottom wall; the first side wall is provided with a first limiting position entering downward and limited from the first extension direction, and the first limiting position opens toward the second side wall along the second extension direction; the second side wall is provided with a second limiting position entering downward and limited from the first extension direction, and the second limiting position opens toward the first side wall along the second extension direction.

[0007] From the above scheme can be seen, the support part is used for supporting the frame rod of the stirring frame, the insertion site is used for inserting the insertion plate on the stirring frame, the first limiting site and the second limiting site are used for accommodating the first connecting end and the second connecting end of the stirring frame in the axial direction, so that the stirring frame matched with the positioning structure group can be limited in the moving freedom degree and the rotating freedom degree in other directions except the upward movement, and the stirring frame can be stably positioned at the fixed position of the turnover box, and the grabbing matching surface of the stirring frame faces upward and is easy to be adsorbed and grabbed by the mechanical hand. Therefore, the turnover box for the stirring frame provided by the utility model meets the positioning requirements of the stirring frame based on the cooperation requirements of automatic unloading and automatic assembly.

[0008] Further, the spacing protrusion is provided as a column.

[0009] From the above, it can be seen that the spacing protrusion provided as a column meets the requirement of forming an insertion slot. Since the number of spacing protrusions on the turnover box is large, this setting can reduce the material used for the turnover box, and the setting can greatly reduce the weight of the turnover box.

[0010] Further, in the positioning structure group, the opposite sides of the turnover box for the stirring frame are each provided with at least one column in the second extension direction.

[0011] From the above, it can be seen that this setting mainly supports the length of the stirring frame on both sides to avoid bending deformation or even damage when the mechanical hand grabs and the stirring frame bears downward pressure.

[0012] Further, the columns of adjacent two positioning structure groups are arranged in a staggered manner.

[0013] From the above, it can be seen that since the insertion plate of the stirring frame is thin, if the two columns are arranged in a straight line in the first extension direction, the spacing between the two columns is small, and the mold thickness and strength corresponding to the spacing are insufficient. Arranging the columns in a staggered manner can solve this problem.

[0014] Further, the top of the spacing protrusion includes a first top surface arranged in steps and a second top surface higher than the first top surface; the first top surface and the second top surface are each part of the support part.

[0015] From the above, it can be seen that the first top surface and the second top surface arranged in steps are more suitable for the two support matching surfaces of the stirring frame, and this setting increases the stability of the stirring frame.

[0016] Further, the first limiting site is out of plane with the insertion site, and / or the second limiting site is coplanar with the insertion site.

[0017] From the above, it can be seen that this setting is more consistent with the relative position of the first connecting end and / or the second connecting end on the stirring frame and the insertion site, has better matching degree, and achieves better limiting effect.

[0018] Still further, the minimum width of the second limiting position in the first extension direction is greater than the minimum width of the first limiting position in the first extension direction.

[0019] As can be seen, the first connecting end is a small short axis and the second connecting end has an outer wall with a larger outer contour and a jack, which makes the first limiting position and the second limiting position more consistent with the structure of the stirring frame, has better matching degree, and achieves better limiting effect.

[0020] Still further, the second side wall comprises reinforcing columns protruding from the inner side thereof in the second extension direction, and at least two reinforcing columns are arranged in the first extension direction; the second side wall comprises a first column portion and a second column portion arranged in sequence from bottom to top, and the size of the first column portion in the first extension direction is greater than the size of the second column portion; the second limiting position is formed between two adjacent second column portions, the jack extends between two adjacent first column portions, the top surface of the first column portion serves as part of the supporting portion, and part of the entrance of the jack is formed at the bottom of the second limiting position.

[0021] As can be seen, since the plugboard extends to the outer wall of the second connecting end, part of the entrance of the jack needs to be arranged below the second limiting position, and the arrangement of the reinforcing columns with small size at the top and large size at the bottom meets the matching requirement with the second connecting end of the stirring frame, has better matching degree, and achieves better limiting effect.

[0022] Still further, the first side wall comprises a thickened plate protruding from the inner side thereof in the second extension direction, and the first limiting position is arranged on the thickened plate.

[0023] Still further, the bottom of the stirring frame turnover box is provided with a downward protruding lower protruding body; in plan view, the lower protruding body is completely located within the entrance of the stirring frame turnover box; and in plan view, at least part of the lower protruding body is coincident with the second column portion and / or at least part of the lower protruding body is coincident with the thickened plate.

[0024] As can be seen, the utility model also considers the stacking problem of the turnover box, and both stacking and damage to the materials placed in the box are avoided, so that the downward protruding lower protruding body is arranged at the bottom of the turnover box, the lower protruding body can be a boss or a boss and a rib plate located at the outer periphery of the boss, when the turnover boxes are stacked, the lower protruding body enters the box from the opening of the turnover box, but is finally limited and supported by the reinforcing columns and the thickened plate, so that the upper turnover box is limited above the materials in the lower turnover box, and stacking is completed without damaging the materials.

[0036] See Figure 1 , Figure 1 This is an axial structural diagram of the mixing frame 9, which can cooperate with the suction head of a robotic arm. The mixing frame 9 includes a support rod 90, with a first connecting end 94 and a second connecting end 95 at its two axial ends. Figure 3 As shown, the frame rod 90 has an adsorption mating surface 91 and a support mating surface 92 at its circumferential position. The adsorption mating surface 91 and the support mating surface 92 are both planes, parallel to each other, and located on opposite sides of the rotation axis of the stirring frame 9. The stirring frame 9 also includes an insert plate 93, which protrudes from the support mating surface 92 perpendicularly. The insert plate 93 is a support plate for the flexible blades to be installed on the stirring frame 9. In this utility model, the insert plate 93 serves as a positioning and mating structure for the stirring frame 9.

[0037] See Figure 2 and Figure 3In the illustrated rectangular coordinate system, the x-axis represents the first extension direction of the bottom wall 11, the y-axis represents the second extension direction of the bottom wall 11, and the z-axis represents the height direction of the mixing rack turnover box. Both the first and second extension directions are horizontal, with the first extension direction being the length direction of the mixing rack turnover box and the second extension direction being the width direction. The height direction of the mixing rack turnover box is vertical. (Combined with...) Figure 1 The x-axis direction also represents the axial direction of the mixing rack 9.

[0038] The mixing rack is equipped with a positioning structure group using a turnover box. Each positioning structure group is used to cooperate with one mixing rack 9. The positioning structure group includes a support, an insertion position, a first limiting position, and a second limiting position.

[0039] See Figure 2 and Figure 3 The mixing rack turnover box includes a bottom wall 11, a peripheral wall 12, and spacer protrusions 13. The peripheral wall 12 is connected to the outer peripheral edge of the bottom wall 11 and extends upward. A plurality of spacer protrusions 13 are disposed on the upper side of the bottom wall 11. The peripheral wall 12 includes a first side wall 121 and a second side wall 122 disposed opposite to each other along the y-axis direction of the bottom wall 11.

[0040] See Figure 2 and Figure 4 The first sidewall 121 includes a thickened plate 14 protruding from its inner surface along the y-axis. Multiple first limiting positions 140 are equidistantly arranged along the x-axis on the thickened plate 14. The thickened plate can restrict the first connecting end 94 within the first limiting position 140 from the x-axis direction. The entrance of the first limiting position 140 is located at the top of the thickened plate 14, i.e., the first limiting position 140 enters downwards. Furthermore, the first limiting position 140 opens towards the second sidewall 122 along the y-axis, and this opening communicates with the entrance of the first limiting position 140. Further, the entrance of the first limiting position 140 is configured as a flared opening that gradually narrows, which facilitates the entry of the first connecting end 94 of the stirring rack 9. Further, the bottom surface of the first limiting position 140 is configured as an arc surface. Since the first connecting end 94 has a circular outer contour, this configuration results in a higher degree of fit between the inner contour of the first limiting position 140 and the outer contour of the first connecting end 94. In addition, the top surface of the reinforcing plate 14—the third top surface 143—is an upward-facing plane.

[0041] See Figure 3 and Figure 5The second sidewall 122 includes reinforcing columns 15 protruding from its inner surface along the y-axis, with multiple reinforcing columns 15 spaced apart along the x-axis. The base of each reinforcing column 15 is connected to the upper surface of the bottom wall 11. Each reinforcing column 15 includes a first column portion 151 and a second column portion 152 arranged sequentially from bottom to top. In the x-axis direction, the size of the first column portion 151 is larger than the size of the second column portion 152, thus creating a stepped arrangement between the first column portion 151 and the second column portion 152. A second limiting position 150 is formed between any two adjacent second column portions 152, extending downwards and restricting access from the x-axis direction. The second limiting position 150 opens towards the first sidewall 121 along the y-axis direction. The top surface of the first column portion 151—the fifth top surface 1511—serves as the bottom surface of the second limiting position 150, and the fifth top surface 1511 is part of the support portion. The fifth top surface 1511 is an upward-facing plane. Since the outer periphery of the second connecting end 95 is approximately square, this arrangement allows for a higher degree of fit between the inner contour of the second limiting position 150 and the outer contour of the second connecting end 95. Furthermore, on the second column portion 152, a chamfer is provided at the upper edge between the fourth top surface 153 and the side facing the second limiting position 150 to form a guide slope. This arrangement increases the entrance to the second limiting position 150, allowing the second connecting end 95 to enter the second limiting position 150 more easily. Additionally, the top surface of the second column portion 152—the fourth top surface 153—is also an upward-facing plane.

[0042] In addition, combined Figure 4 , Figure 5 as well as Figure 7 The minimum width of the second limiting position 150 in the x-axis direction is greater than the minimum width of the first limiting position 140 in the x-axis direction. The minimum width of the second limiting position 150 in the x-axis direction refers to the dimension at the minimum interval between two adjacent second column portions 152, and the minimum width of the first limiting position 140 in the x-axis direction is the diameter of its bottom arc surface.

[0043] See Figure 2 and Figure 6 The spacer protrusion 13 is configured as a column. The top of the spacer protrusion 13 includes a first top surface 131 arranged in a stepped manner and a second top surface 132 higher than the first top surface 131. Both the first top surface 131 and the second top surface 132 are upward-facing planes. Both the first top surface 131 and the second top surface 132 serve as part of a support portion. Furthermore... Figure 7 In each positioning structure group, at least one column is provided on each of the opposite sides of the mixing rack turnover box along the y-axis direction; and, along the y-axis direction, the columns of any two adjacent positioning structure groups on the same side of the mixing rack turnover box are staggered, and the columns of all positioning structure groups are arranged along a continuous bending line.

[0044] Between the spacer protrusions 13 of two adjacent positioning structure groups, a downwardly entering insertion position 130 is formed, extending along the y-axis direction, and combined with... Figure 5 The insertion position 130 extends between two adjacent first post portions 151, and a portion of the entrance to the insertion position 130 is formed at the bottom surface of the second limiting position 150. It can be seen that the second limiting position 150 is coplanar with the insertion position 130. Furthermore, as... Figure 7 As shown, the first limiting position 140 and the insertion position 130 are on opposite sides.

[0045] See Figure 2 , Figure 3 as well as Figure 8 When the mixing rack 9 is placed in the box, it engages with a positioning structure assembly. First, the supporting mating surface 92 rests on the first top surface 131 of the column, and a higher inner surface of the mixing rack 9 rests on the second top surface 132 of the column. The insert plate 93 is inserted into the insertion position 130, the first connecting end 94 is located in the first limiting position 140, and the second connecting end 95 is located in the second limiting position 150. In this way, the mixing rack 9 can move upward, and its other directions of movement and rotational freedom are restricted. This ensures that the mixing rack 9 remains stable in its current position during turnover. Furthermore, the adsorption mating surface 91, which is opposite to the supporting mating surface 92, faces upward and is easily adsorbed and grasped by the robotic arm.

[0046] See Figure 9 The bottom of the mixing rack turnover box is provided with a downwardly protruding lower protrusion 16, which includes a boss 161 and a rib plate 162 connected to the outer periphery of the boss 161.

[0047] See Figure 10 and Figure 11 On a top-view projection, i.e., on the z-axis, the lower protrusion 16 is completely within the inlet of the mixing rack turnover box. Thus, when two mixing rack turnover boxes are stacked, the lower protrusion 16 of the upper mixing rack turnover box can enter the inlet of the lower mixing rack turnover box. Furthermore, on a top-view projection, at least a portion of the lower protrusion 16 coincides with the second column 152, and at least a portion of the lower protrusion 16 coincides with the thickening plate 14. Thus, the downward movement of the lower protrusion 16 will be blocked by the second column 152 and the thickening plate 14. Ultimately, the two side stiffeners 162 of the lower protrusion 16 will be supported on the fourth surface 153 of the second column 152 and the third surface 143 of the thickening plate 14, respectively. Since the mixing rack 9 in the lower mixing rack turnover box is located below the third surface 143 and the fourth surface 153, the upper mixing rack turnover box still maintains a certain distance from the lower mixing rack 9, thus completing the stacking while preventing material damage.

[0048] In other embodiments, the spacer protrusions may be configured as plate-like structures.

[0049] In other embodiments, the columns of two adjacent positioning structure groups are arranged in a straight line along the first extending direction.

[0050] In other embodiments, the top surface of the spacer protrusion does not include the second top surface.

[0051] In other embodiments, no thickening plate is provided, and the first limiting position is recessed into the inner surface of the first sidewall itself. Similarly, no reinforcing column is provided, and the second limiting position is recessed into the inner surface of the second sidewall itself.

[0052] In other embodiments, the lower protrusion includes only a boss, which, in a top view, coincides with the second column portion, and / or the boss coincides with the thickened plate.

[0053] In other embodiments, no lower protrusion is provided.

[0054] Finally, it should be emphasized that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
