Technical Field

[0001] The utility model relates to the technical field of material transfer vehicles, in particular to a layered bottom plate opening and closing structure based on a material transfer vehicle. Background Art

[0002] The aging test of electronic products is an important quality control process used to ensure the reliability and durability of semiconductor products. This test accelerates the emergence of potential defects in semiconductor devices by simulating stress conditions in the actual application environment, such as temperature, voltage, and power cycling. The purpose of the aging test is to detect and eliminate products that may experience early failures as early as possible, thereby improving the reliability of chip usage.

[0003] In the prior art, the tested electronic products are stacked on a transfer vehicle and transported to a high-temperature test workshop by the transfer vehicle to achieve the high-temperature aging test of multiple groups of electronic products. In the prior art, during the stacking process of electronic products with a relatively large weight, most of them are lifted to a certain height by a crane. However, since it is not easy to disassemble and assemble the pallet used for placing materials on the transfer vehicle, it is usually inconvenient for the operator to take and place products in the narrow space between the upper and lower layers of the material rack, resulting in the problem that the prior art is not easy to operate by the operator.

[0004] Based on the above defects, a layered bottom plate opening and closing structure based on a material transfer vehicle is provided. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a layered bottom plate opening and closing structure based on a material transfer vehicle in order to solve the above problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: A layered bottom plate opening and closing structure based on a material transfer vehicle, including a vehicle frame;

[0007] A plurality of groups of pallets capable of sliding and opening and closing are vertically slid on the vehicle frame, and the number of each group of pallets is two. A supporting structure for cooperating with the pallets to place materials is installed on the vehicle frame;

[0008] A sliding housing is slidably arranged on the supporting structure, and both sides of the pallet are rotatably connected to the sliding housing through a hinged structure.

[0009] Preferably, the supporting structure includes a first cross beam, a second cross beam and a sliding and supporting component installed on the vehicle frame. Two first cross beams are arranged on one side of each group of pallets perpendicular to the second cross beam horizontally.

[0010] Preferably, the sliding and supporting component is a sliding beam slidably arranged between two second cross beams distributed horizontally at the same level.

[0011] Preferably, the vehicle frame, the first cross beam, and the second cross beam are all 4040 aluminum profiles, and are connected by corner brackets and bolts.

[0012] Preferably, the hinge structure includes side retaining shells fixedly arranged on both sides of the support plate relative to the first cross beam, and the side retaining shells and the sliding connection shell are rotatably connected by hinges.

[0013] Preferably, a retaining frame perpendicular to the sliding connection shell is fixedly arranged at the outer end of the sliding connection shell, and the retaining frame is slidably embedded between the two first cross beams. By the vehicle frame blocking the retaining frame, the sliding range of the sliding connection shell is limited.

[0014] Preferably, both the side retaining shell and the sliding connection shell are hollow structures, and the length of the side retaining shell is shorter than the length of the side where it is fixed to the support plate.

[0015] Preferably, protrusions extending into the second cross beam are formed at both ends of the sliding beam, and retaining hooks are fixedly arranged at both ends of the sliding beam extending into the second cross beam.

[0016] Preferably, a handle is fixedly arranged on the support plate, and a folded edge is integrally formed on the support plate. When the folded edge abuts against the inner wall of the second cross beam, the sliding opening of the support plate can be restricted.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] Please refer to Figures 1 - 5 , the present invention provides a technical solution: a layered bottom plate opening and closing structure based on a material transfer vehicle, including a frame 1. The frame 1 is a multi-layer structure for layered stacking of multiple groups of test materials. The material vehicle is composed of sheet metal parts, profiles, universal wheels, bearings, connectors, and handrails. All the components are made of high-temperature resistant materials and connected by corner bolts to enable the material vehicle to work in high-load and high-temperature environments.

[0029] A plurality of groups of pallets 4 that can slide open and close are vertically slidable on the frame 1. The number of each group of pallets 4 is two. A supporting structure for supporting and placing the pallets 4 is installed on the frame 1; through a plurality of groups of vertically distributed pallets 4, it is used for layered stacking of test materials, so as to meet the synchronous aging test of multiple materials and achieve the purpose of improving the detection efficiency.

[0030] The supporting structure is used to horizontally place the pallet 4 relative to the frame 1 and bear the weight of the pallet 4 and the materials stacked on the pallet 4.

[0031] Through the pallet 4 that can slide open and close, when the crane is transporting the materials on the production line to the vehicle, the user can slide and open the pallet 4, so that the materials pass through the gap formed between the pallets 4 and fall onto the pallet 4 in the closed state. After completing the stacking and loading of the lower-layer materials, the user then closes the upper-layer pallet 4, and then realizes the layer-by-layer stacking of the materials, so as to facilitate the user to stack and load the heavier materials on the material vehicle in a hoisting manner.

[0032] A sliding housing 8 is slidably arranged on the supporting structure, and both sides of the pallet 4 are rotatably connected to the sliding housing 8 through a hinge structure.

[0033] When the pallet 4 slides horizontally along the vehicle frame 1, it can drive the sliding housing 8 to slide synchronously with it. After the pallet 4 is pulled out a certain length, the pallet 4 can rotate along the sliding housing 8 through the hinge structure. Furthermore, after the pallet 4 is pulled out and opened relative to the vehicle frame 1, it can be rotated to a vertical state and hung on both sides of the vehicle frame 1, so as to achieve the purpose of reducing the occupation of the vehicle body space, which is beneficial for the user to perform auxiliary operations around the material vehicle.

[0034] Specifically, as Figure 1 and Figure 2 shown, the supporting structure includes a first cross beam 2, a second cross beam 3 and a sliding support assembly installed on the vehicle frame 1. On the side of each group of pallets 4 perpendicular to the second cross beam 3 horizontally, two first cross beams 2 are arranged. A frame for the pallet 4 to be movably placed is formed among the vehicle frame 1, the first cross beam 2 and the second cross beam 3, and the sliding support assembly is used to support the middle part of the horizontally installed pallet 4, so as to achieve the purpose of improving the safe loading of the heavier materials by the pallet 4.

[0035] When the pallet 4 is opened and hung relative to the vehicle frame 1, the user moves the sliding support assembly to the side of the vehicle frame 1 to provide space for the feeding and placing of the materials.

[0036] The sliding support assembly is a sliding beam 11 slidably arranged between two second cross beams 3 distributed horizontally. The vehicle frame 1, the first cross beam 2 and the second cross beam 3 are all 4040 aluminum profiles, which are connected by corner codes and bolts. Raised parts extending into the second cross beam 2 are formed at both ends of the sliding beam 11, and retaining hooks 12 are fixedly installed at both ends of the sliding beam 11 extending into the second cross beam 2.

[0037] The 4040 aluminum profile has a small density and light weight, and at the same time has the advantages of high strength and hardness, can withstand greater pressure and impact, and a dense oxide film can be naturally formed on the surface of the aluminum material, effectively preventing corrosion, and is suitable for complex test environments.

[0038] While meeting the body strength, the body weight is reduced by using 4040 aluminum profiles. The end faces around this profile are in a hollow structure, and both ends of the sliding beam 11 extend into the hollow grooves for sliding support of the sliding beam 11. Through the resistance of the retaining hook 12 against the inner wall of the groove of the first cross beam 2, the sliding beam 11 is prevented from slipping out between the two first cross beams 2, which is beneficial for the sliding beam 11 to stably support the pallet 4.

[0039] Specifically, as Figures 1 - 3 shown, a retaining frame 10 is fixedly arranged at the outer end of the sliding connection shell 8 and is vertically distributed therewith. The retaining frame 10 is slidably embedded between the two first cross beams 2. Through the blocking of the retaining frame 10 by the vehicle frame 1, the sliding range of the sliding connection shell 8 is restricted.

[0040] The retaining frame 10 slides along the gap formed between the two first cross beams 2, and this gap is matched with the height of the retaining frame 10 to avoid the situation that the retaining frame 10 rotates and warps relative to the first cross beam 2, which affects the stable opening and closing of the pallet 4.

[0041] The hinge structure includes side retaining shells 7 fixedly arranged on both sides of the pallet 4 relative to the first cross beam 2. The side retaining shells 7 and the sliding connection shell 8 are rotatably connected by a hinge 9. Both the side retaining shells 7 and the sliding connection shell 8 are hollow structures, and the length of the side retaining shells 7 is shorter than the length of the side where the pallet 4 is fixed thereto.

[0042] The use of hollow structures reduces the material consumption of non-load-bearing parts, reduces costs and further reduces the body weight. By shortening the length of the side retaining shells 7 relative to the pallet 4, when the hinge joint between the side retaining shells 7 and the sliding connection shell 8 slides out of the second cross beam 3, the pallet 4 can be rotated. At this time, the pallet 4 has not completely slid out of the vehicle frame 1, and the rotation suspension of the pallet 4 can be realized, achieving the purpose of facilitating personnel operation.

[0043] Specifically, as Figure 1 and Figure 5 shown, a handle 5 is fixedly arranged on the pallet 4, and a hem 6 is integrally formed on the pallet 4. When the hem 6 abuts against the inner wall of the second cross beam 3, the sliding opening of the pallet 4 can be restricted.

[0044] The user operates the sliding opening and closing of the pallet 4 through the handle 5. When the user closes the pallet 4, as the pallet 4 is closed in place, the user releases the handle 5. The pallet 4 will sink slightly under the action of gravity. At this time, the hem 6 formed on the pallet 4 will be located inside the second cross beam 3, thereby restricting the pallet 4 from sliding outwards relative to the vehicle frame 1 and ensuring that the pallet 4 is in a stable closed state when placing materials.

[0045] When the user pulls out the pallet 4, the user needs to gently lift the pallet 4 through the handle 5 to release the resistance of the inner wall of the second cross beam 3 against the hem 6. At this time, the pallet 4 can be pulled to slide and open relative to the vehicle frame 1.

[0046] The above description of the embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
