Description

Technical Field

[0001] This utility model relates to the field of vehicle welding fixture stacking structure, and in particular to a multifunctional material box conveying rack. Background Technology

[0002] With the increasing demand for personalized products in the automotive consumer market, automakers are gradually shifting to a multi-model co-production model. As a core part of automobile manufacturing, the body-in-white welding workshop needs to simultaneously accommodate welding operations for 2-5 different platform models. The storage and flow of corresponding fixtures, positioning parts, and other materials have become key factors affecting production efficiency.

[0003] Currently, the mainstream material stacking method in the body-in-white welding workshop is to lay the materials flat on the ground: the fixtures for different car models are directly arranged and placed on the ground at the material inlet or on a simple flat rack. This method has significant limitations: On the one hand, flat stacking requires a lot of workshop space, while welding workshops are densely packed with welding robots, conveyor lines and other equipment, making space already tight. Material stacking is prone to conflict with equipment layout and personnel operation paths, resulting in narrow workshop logistics channels and affecting production turnover efficiency.

[0004] On the other hand, when materials from multiple vehicle models are mixed and stacked or laid out in different areas, sufficient material opening width must be reserved to distinguish materials from different vehicle models. This not only further exacerbates the waste of space, but also easily leads to the problem of materials being mixed or taken by mistake. Moreover, when switching vehicle models, the material area needs to be reorganized and the stacking position adjusted, which is cumbersome and time-consuming, and it is difficult to adapt to the rapid switching requirements of co-line production.

[0005] Therefore, in the context of multi-vehicle co-production in welding workshops, there is an urgent need to develop a mechanism that can reduce space occupation and enable rapid material switching and stacking for multiple vehicle models. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology, such as large material stacking space occupation and insufficient vehicle model adaptability, and to provide a multi-functional material box conveying rack.

[0007] The objective of this utility model can be achieved through the following technical solutions: A multifunctional material box conveying rack includes a rack body, which includes multiple mounting frames. Each mounting frame is distributed in parallel along the vertical direction, and the distance between adjacent mounting frames is greater than the height of the material box. Each layer of the mounting frame is equipped with multiple parallel sliding assemblies. The mounting frames of the main body of the material rack are divided into a positioning layer and a return layer. The sliding assemblies of the positioning layer are inclined downward from the feeding end of the material rack to the feeding end, and the sliding assemblies of the return layer are inclined upward from the feeding end of the material rack to the feeding end.

[0008] Preferably, the mounting frame includes a first rectangular mounting frame and a second rectangular mounting frame that are parallel to each other, with the first rectangular mounting frame located above the second rectangular mounting frame and spaced apart.

[0009] Preferably, one end of the flow strip sliding assembly of the positioning layer is mounted on the first rectangular mounting frame at the feeding end of the material rack, and the other end is mounted on the second rectangular mounting frame at the feeding end of the material rack.

[0010] Preferably, one end of the flow strip sliding assembly of the return layer is mounted on the second rectangular mounting frame at the feed end of the material rack, and the other end is mounted on the first rectangular mounting frame at the feed end of the material rack.

[0011] Preferably, the inner side of the first rectangular mounting frame is provided with an elastic buffer pad.

[0012] Preferably, the tilt angle of the smooth strip sliding assembly is 10-20 degrees.

[0013] Preferably, the smooth strip sliding assembly includes a fixed frame and a plurality of pulleys, the pulleys being rotatably mounted on the fixed frame, the pulleys being parallel to each other, the upper ends of the pulleys being higher than the upper end surface of the fixed frame, and the fixed frame being inclinedly fixed on the mounting frame.

[0014] Preferably, U-shaped hooks are symmetrically installed at both ends of the fixing frame, and the U-shaped hooks are bolted to the mounting frame.

[0015] Preferably, the lower end of the material rack body is provided with multiple casters, and each caster is evenly distributed on the four corners of the material rack body.

[0016] Preferably, the caster wheel is equipped with a self-locking mechanism.

[0017] Compared with the prior art, the present invention has the following advantages: (1) This solution uses a layered structure for the installation frame. The sliding components of the flow strips of each layer of the installation frame are set at an angle, so that the material box can be conveyed by its own gravity. The material transfer layer and the corresponding empty material box recycling layer are set up, which can efficiently match the material supply needs of multiple models of the welding workshop in the same production line, improve the efficiency of material flow and storage, and the layered vertical structure greatly reduces the space occupancy rate of the multi-model material rack.

[0018] (2) In this scheme, an elastic buffer pad is provided on the inner side of the first rectangular mounting frame near the low end of the flow strip sliding component to buffer the impact after the material box slides down, protect the material box and the frame, and extend the service life and stability of the device.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0026] Example 1 like Figure 1 and Figure 3 As shown, this embodiment provides a multifunctional material box conveying rack, characterized in that it includes a rack body 1, the rack body 1 includes multiple mounting frames 101, each mounting frame 101 is distributed in parallel along the vertical direction, and the distance between adjacent mounting frames 101 is greater than the height of the material box. Each mounting frame 101 is equipped with multiple parallel sliding components 2. Each mounting frame 101 of the material rack body 1 is divided into a positioning layer 3 and a return layer 4. The sliding components 2 of the positioning layer 3 are inclined downward from the feeding end of the material rack to the feeding end, and the sliding components 2 of the return layer 4 are inclined upward from the feeding end of the material rack to the feeding end.

[0027] Working principle: The delivery layer is marked according to the vehicle model. The delivery personnel place the material box of the corresponding vehicle model into the feeding end of the corresponding delivery layer 3. Based on the inclined structure of the flow strip sliding component 2 and the gravity of the material box, it automatically slides to the delivery end. The pick-up personnel take the material according to the corresponding vehicle model and place it. Then, the empty material box is placed on the return layer 4, and it automatically slides to the feeding end in the same way. The delivery personnel collect it in a unified manner.

[0028] By using the layered structure of the mounting frame, the flow strip sliding component 2 of each layer of the mounting frame is set at an inclination, allowing the material box to be conveyed by its own gravity. The system includes a material transfer layer and a corresponding empty material box recycling layer, which can efficiently match the material supply needs of multiple vehicle models produced on the same production line in the welding workshop, improve the efficiency of material flow and storage, and the layered vertical structure significantly reduces the space occupancy rate of the multi-vehicle material rack.

[0029] Specifically, the main body 1 of the material rack is welded from Q235 carbon steel, with overall dimensions of 3000mm (length) × 800mm (width) × 2400mm (height). It includes four vertically parallel mounting frames 101, with a vertical spacing of 250mm between adjacent mounting frames 101, which is 200mm greater than the height of a standard material box, ensuring smooth loading and unloading of the material boxes. Of the four mounting frames 101, the top three layers are the placement layers 3, used to store full material boxes, and the bottom layer is the return layer 4, used to recycle empty material boxes. Each mounting frame 101 is welded and fixed to the main body 1 of the material rack with reinforcing ribs, and the load-bearing capacity is no less than 500kg per layer.

[0030] Preferred implementation methods, such as Figure 2 As shown, the mounting frame 101 includes a first rectangular mounting frame 102 and a second rectangular mounting frame 103 that are parallel to each other. The first rectangular mounting frame 102 is located above the second rectangular mounting frame 103 and they are spaced apart.

[0031] One end of the flow strip sliding assembly 2 of the arrival layer 3 is mounted on the first rectangular mounting frame 102 at the feed end of the material rack, and the other end is mounted on the second rectangular mounting frame 103 at the discharge end of the material rack. One end of the flow strip sliding assembly 2 of the return layer 4 is mounted on the second rectangular mounting frame 103 at the feed end of the material rack, and the other end is mounted on the first rectangular mounting frame 102 at the discharge end of the material rack.

[0032] Specifically, each mounting frame 101 consists of a first rectangular mounting frame 102 and a second rectangular mounting frame 103 that are parallel to each other. Both are square frames with a side length of 800mm and can be welded using 50×50mm square tubing. The first rectangular mounting frame 102 is located directly above the second rectangular mounting frame 103 with a vertical spacing of 150mm, and is fixedly connected by 4 longitudinal connecting rods to form a stable double-layer mounting base.

[0033] The inner side of the first rectangular mounting frame 103 is provided with an elastic buffer pad. The elastic buffer pad provided on the inner side of the first rectangular mounting frame near the lower end of the flow strip sliding assembly buffers the impact after the material box slides down, protects the material box and the frame, and also supports the material box, extending the service life and stability of the device.

[0034] In this embodiment, the tilt angle of the flow strip sliding assembly 2 is 10-20 degrees. This ensures that the hopper can slide smoothly along the flow strip while avoiding... In this embodiment, the flow strip sliding assembly 2 includes a fixed frame 21 and multiple pulleys 22. The pulleys 22 are rotatably mounted on the fixed frame 21, and each pulley 22 is parallel to the others. The upper end of each pulley 22 is higher than the upper surface of the fixed frame 21. The fixed frame 21 is obliquely fixed to the mounting frame 101. U-shaped hooks 23 are symmetrically installed at both ends of the fixed frame 21, and the U-shaped hooks 23 are bolted to the mounting frame 101.

[0035] The flow strip sliding assembly 2 is the core transmission component. 5-10 sets are installed in parallel on each layer of the mounting frame 101, with the spacing between each set adjusted according to the material box width. The fixing frame 21 is made of 30×20mm cold-formed steel, its length adapted to the mounting frame 101, and its surface is galvanized for rust prevention. The pulleys 22 are made of nylon, 30mm in diameter and 10mm thick. 30 pulleys 22 are evenly distributed on each fixing frame 21, with a center-to-center distance of 50mm between adjacent pulleys 22. The pulleys 22 are rotatably mounted on the fixing frame 21 via stainless steel pins, and the upper end of the pulley 22 is 5mm higher than the upper surface of the fixing frame 21 to reduce friction between the material box and the fixing frame. U-shaped hooks 23 are symmetrically welded to both ends of the fixing frame 21, and the U-shaped hooks 23 are securely connected to the mounting frame 101 with M8 stainless steel bolts to ensure the fixing frame does not loosen.

[0036] In this embodiment, the lower end of the material rack body 1 is provided with multiple casters 5, which are evenly distributed on the four corners of the material rack body 1. Each caster 5 is equipped with a self-locking mechanism. Heavy-duty casters 5 with a load capacity of 500kg are installed at the four corners of the lower end of the material rack body 1. The casters 5 are equipped with a foot-operated self-locking mechanism; pressing the self-locking pedal locks the wheel; pushing unlocks it, allowing the material rack to move flexibly within the workshop and adapt to production line layout adjustments.
