Description

Technical Field

[0001] This invention relates to the fields of automated production and assembly, and in particular to a large-angle material rack with adjustable verticality. Background Technology

[0002] In automated production and assembly, workpieces are often placed on racks for temporary storage before being picked up by robotic arms or other picking mechanisms. To improve space utilization, it is desirable to place more workpieces on the same rack.

[0003] For sheet metal workpieces, traditional racks are simple multi-layer structures where multiple workpieces are placed in different layers or compartments. However, this type of rack has the following problems: First, both storing and retrieving require a large amount of horizontal space, meaning that space needs to be reserved in the workshop for storing workpieces, thus affecting the layout of other mechanisms in the workshop; Second, due to the limitation of the storage and retrieval direction, when using a traditional robotic arm to pick up a workpiece, the robotic arm can only support the edge of the workpiece. Therefore, from the time the workpiece is taken out to the time it is placed on the production line (assembly line), the workpiece is always in a cantilevered state. If the workpiece is heavy, there is a certain safety hazard, and the workpiece is also prone to deformation or even breakage.

[0004] Therefore, a method or apparatus is needed to solve the above problems. Summary of the Invention

[0005] The present invention addresses the aforementioned shortcomings of the prior art by proposing a large-angle material rack with adjustable verticality that improves safety during the transfer process and prevents deformation of the workpiece itself.

[0006] The technical solution of this invention is: a large-angle material rack with adjustable verticality, characterized in that: the material rack includes a base 1, a support 2 connected to the base 1, and n swinging components 3 arranged on the support 2, where n is a natural number greater than or equal to 3, and all the swinging components 3 are sequentially labeled as the 1st swinging component, the 2nd swinging component, ..., the nth swinging component, from bottom to top. The swing member 3 is rotatably connected to the bracket 2 via a first connecting shaft 4 located in its middle. One end of the swing member 3 is provided with a support plate 5, and the other end is provided with a limit block 6. At the same time, a limiting stop 7 that can contact the limiting block 6 is also provided on the side edge of the bracket 2. When the limiting block 6 contacts the limiting stop 7, the support plate 5 is horizontally distributed. The bottom of the swing member 3 is an arc-shaped part 8, and the top is a straight part 9. When the support plate 5 on the m-th swing member is horizontally distributed, the end where the upper limit block 6 is located will contact the arc portion 8 of the (m+1)-th swing member, and the bracket 2 of the (m+1)-th swing member will protrude from the outer contour of the bracket 2, and m≤n-2. The bottom of the bracket 2 is rotatably connected to the base 1 via a second connecting shaft 10, and the bracket 2 and the base 1 are also fixedly connected by multiple fastening bolts 11. Two adjusting bolts 12 are threadedly connected to the base 1, and a tightening nut 13 is threadedly connected to the adjusting bolts 12. The two adjusting bolts 12 are located on both sides of the bracket 2, and the ends of the adjusting bolts 12 can contact the support plate 5.

[0007] The included angle between the straight section 9 and the support plate 5 is 135°.

[0008] The bottom of the bracket 2 is provided with a limiting shaft 14, which is located above the straight part 9 of the first swing member. When the straight part 9 of the first swing member contacts the limiting shaft 14, the support plate 5 of the first swing member protrudes from the outer contour of the bracket 2.

[0009] Compared with the prior art, the present invention has the following advantages: This type of adjustable vertical angle material rack features a simple structure, ingenious design, and reasonable layout. Addressing the problems of traditional material racks, it employs a unique structure with multiple swinging components on its support plate. In a free state, these components naturally tilt, causing the support plate to retract into the bracket. However, the bottom swinging component protrudes from the bracket's outline under the action of a limiting shaft, allowing it to contact the edge of the supported workpiece. When a workpiece is placed on the bottom swinging component, it pushes the adjacent swinging component above it, causing its support plate to protrude from the bracket's outline, thus supporting the next workpiece. This material rack allows for the immediate loading and unloading of workpieces, with all loading and unloading directions being longitudinal. This enables a robotic arm (or suction cup) to reliably grasp the workpiece, improving safety during transport and preventing workpiece deformation. At the same time, it can also adjust the verticality between the bracket and the base to avoid the problem of the workpiece not being able to be properly supported due to deviation in the verticality of the bracket. Furthermore, the swinging component on its support has a relatively large swing angle, which effectively ensures that the swinging component does not protrude beyond the outer contour of the support when not in use, thus ensuring that the workpieces can be placed normally in sequence. In conclusion, this type of material rack has many advantages and is particularly suitable for widespread application in this field, with a very broad market prospect. Attached Figure Description

[0017] Specific embodiments of the present invention will now be described in conjunction with the accompanying drawings. Figures 1 to 7 As shown: A large-angle material rack with adjustable verticality includes a base 1, a support 2 connected to the base 1, and n swinging components 3 arranged on the support 2, where n is a natural number greater than or equal to 3. All the swinging components 3 are sequentially labeled as swinging component 1, swinging component 2, ..., swinging component n from bottom to top. The swing member 3 is rotatably connected to the bracket 2 via a first connecting shaft 4 located in its middle. One end of the swing member 3 is provided with a support plate 5, and the other end is provided with a limit block 6. At the same time, a limiting stop 7 that can contact the limiting block 6 is also provided on the side edge of the bracket 2. When the limiting block 6 contacts the limiting stop 7, the support plate 5 is horizontally distributed. The bottom of the swing member 3 is an arc-shaped part 8, and the top is a straight part 9. When the support plate 5 on the m-th swing member is horizontally distributed, the end where the upper limit block 6 is located will contact the arc portion 8 of the (m+1)-th swing member, and the bracket 2 of the (m+1)-th swing member will protrude from the outer contour of the bracket 2, and m≤n-2. The bottom of the bracket 2 is rotatably connected to the base 1 via a second connecting shaft 10, and the bracket 2 and the base 1 are also fixedly connected by multiple fastening bolts 11. Two adjusting bolts 12 are threadedly connected to the base 1, and a tightening nut 13 is threadedly connected to the adjusting bolts 12. The two adjusting bolts 12 are located on both sides of the bracket 2, and the ends of the adjusting bolts 12 can contact the support plate 5.

[0018] The included angle between the straight section 9 and the support plate 5 is 135°.

[0019] The bottom of the bracket 2 is provided with a limiting shaft 14, which is located above the straight part 9 of the first swing member. When the straight part 9 of the first swing member contacts the limiting shaft 14, the support plate 5 of the first swing member protrudes from the outer contour of the bracket 2.

[0020] The working process of the adjustable vertical angle material rack in this embodiment of the invention is as follows: When the material rack is working, an appropriate number of material racks need to be selected according to the outer contour of the supported workpiece 15. For example, when the cross-section of the workpiece 15 is rectangular, six material racks are required, and they are arranged as follows: Figure 1 The components are distributed as shown to collectively support workpiece 15. When no workpiece 15 is placed, since the weights on both sides of the first connecting shaft 4 on the swing member 3 are not equal, the swing member 3 will tilt towards the heavier side in the free state. In this state, all the support plates 5 are retracted inside the bracket 2. At this time, the support plates 5 will not protrude from the outer contour of the bracket 2. This state is the non-working state. However, the posture of the bottommost swing member 3, i.e. the first swing member, is affected by the limiting shaft 14, causing the support plate 5 on it to be unable to retract into the bracket 2. So when the workpiece 15 is placed in the space between multiple racks, since the upper swing member 3 is in a yielding state, the workpiece 15 can be directly placed into the bottom layer and contact the support plate 5 protruding from the first swing member. Under the action of the workpiece 15, the first swing members in all racks will swing until the limiting block 6 on it contacts the limiting edge 7. At this time, the support plate 5 in the first swing member is in a horizontal state. This state is the working state. That is, in the working state, the first swing members in all racks jointly support the first workpiece 15. Since the first swinging member is in working condition, one end of its limiting block 6 will contact the arc portion 8 of the second swinging member, pushing the second swinging member to swing. The support plate 5 in the second swinging member protrudes, which is the intermediate state. The second swinging member in the intermediate state will not drive the third swinging member to swing, that is, the support plate 5 in the third swinging member remains retracted inside the bracket 2. In this state, when the second workpiece 15 is placed, the edge of the workpiece 15 will contact the support plate 5 in the second swinging member, driving all the second swinging members to swing downward. When the limiting blocks 6 in all the second swinging members contact the limiting stop 7, the support plates 5 on them are horizontally distributed and support the workpiece 15... By repeating the above process, multiple workpieces 15 can be supported by these racks; When the workpiece 15 supported on the m-th swinging component is removed (m≤n-2), the heavier m-th swinging component will swing in the opposite direction. However, since the (m-1)-th swinging component below it is in working condition, the m-th swinging component is in the middle state under the action of the (m-1)-th swinging component. When the operator needs to pick up the (m-1)-th swinging component, since the m-th swinging component can swing freely at this time, when the edge of the workpiece 15 touches the m-th swinging component from bottom to top, the m-th swinging component swings accordingly to make way. After the (m-1)-th swinging component loses the pressure of the workpiece 15, it will automatically swing to the middle state. Without the influence of the (m-1)-th swinging component, the m-th swinging component naturally swings to the non-working state, and the support plate 5 on it is retracted into the bracket 2. The (m-1)-th swinging component then swings to the middle state, waiting for the next operation of picking up or placing a workpiece.

[0021] If there is a large deviation in the verticality accuracy between the bracket 2 and the base 1, the workpiece 15 may not be able to contact the support plate 5 on the corresponding swinging part 3 in the middle state during the placement process, resulting in the workpiece 15 being unable to be stored properly. When the above problems occur, the operator can loosen the fastening bolt 11 between the bracket 2 and the base 1, and then rotate the two adjusting bolts 12 respectively. The adjusting bolts 12 move axially relative to the base 1, thereby pushing the bracket 2 to swing slightly around the second connecting shaft 10. After the bracket 2 is adjusted to the appropriate position, the adjusting bolts 12 are tightened and fixed using the spare nut 13, and then the fastening bolts 11 are tightened. This completes the adjustment of the vertical accuracy of the bracket 2. The above operation is performed on all the material racks to ensure that the swinging part 3 in each material rack can properly support the workpiece 15.
