Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0030] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] In the description of this embodiment, the terms "upper," "lower," "left," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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 the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0033] like Figures 1-9The illustration shows an automated loading and unloading rack proposed in an embodiment of the present invention. It can move goods, not limited to testing machines, to predetermined positions on the rack, or remove goods from the rack, thus achieving automated loading and unloading. This automated loading and unloading rack includes a frame 1 with multiple storage layers 11, a lifting mechanism 3, and an infeed / outfeed mechanism 2. Each storage layer 11 has multiple storage stations along a first direction, and multiple goods can be placed one-to-one on multiple storage stations. Multiple sets of infeed / outfeed mechanisms 2 are correspondingly arranged on the multiple storage layers 11 of the frame 1. The infeed / outfeed mechanism 2 includes a first translation component 21, a second translation component 22, and a gripping component 23. The first translation component 21 can drive the gripping component 23 to move along the first direction (X direction in the figure), and the second translation component 22 can drive the gripping component 23 to move along the first direction (X direction in the figure). Component 23 moves along the second direction (Y direction in the figure). Two gripping components 23 are provided along the first direction, one for feeding (placing goods on the frame 1) and the other for discharging (removing goods from the frame 1). The lifting mechanism 3 is provided on one side of the frame 1 and includes a lifting component 31 and a loading tray 32. The lifting component 31 can drive the loading tray 32 to move along a third direction (Z direction in the figure). Two loading trays 32 are also provided along the first direction, one for carrying the discharging goods on the gripping component 23 and the other for providing feeding goods to the gripping component 23. The first direction, the second direction, and the third direction are perpendicular to each other. In this embodiment, the third direction is the vertical direction.

[0034] The aforementioned automated loading and unloading rack enables automatic loading and unloading of goods on the rack 1. Moreover, the lifting mechanism 3 is equipped with two material trays 32, and the loading and unloading mechanism 2 is equipped with two material gripping components 23. In one reciprocating motion, it can simultaneously complete the two actions of transferring goods to the rack 1 and removing goods from the rack 1, further improving the efficiency of automatic loading and unloading.

[0035] The first translation component 21 in the feeding / discharging mechanism 2 has various forms, see reference. Figure 1 As shown, the first translation component 21 uses a conveyor belt structure for transport. Specifically, the first translation component 21 includes a first drive unit 214, translation conveyor belt pulleys 212, a translation conveyor belt 213, and a translation frame 211. The translation frame 211 extends along a first direction and is mounted on the frame 1. Two translation conveyor belt pulleys 212 are spaced apart along the first direction on the translation frame 211 and connected by the translation conveyor belt pulleys 212. One of the translation conveyor belt pulleys serves as the drive pulley and is connected to the first drive unit 214. The first drive unit 214 is a motor.

[0036] The second translation component 22 is disposed at the output end of the first translation component 21. The second translation component 22 includes a second driving member 222 and a translation base plate 221. The translation base plate 221 is disposed on the translation conveyor belt 213 and moves with the translation conveyor belt 213. The translation base plate 221 is slidably connected to the translation frame 211. The second driving member 222 is disposed on the translation base plate 221 and connected to the material gripping component 23, thereby driving the material gripping component 23 to move in a second direction on the translation base plate 221. Exemplarily, the second driving member 222 is a cylinder or a hydraulic cylinder.

[0037] refer to Figures 7-9 As shown, the distance between the two gripping components 23 is the same as the distance between two adjacent storage stations. The two gripping components 23 use the same set of first translation components 21 to move along the first direction, but use two sets of second translation components 22 to move along the second direction respectively. That is to say, the movement of the two gripping components 23 along the second direction is executed independently to simultaneously perform feeding and discharging actions, thereby improving feeding and discharging efficiency. The gripping components 23 can adopt structures such as grippers or suction cups. In this embodiment, no specific restrictions are imposed, as long as they can cooperate with the first translation components 21 and the second translation components 22 to transfer goods.

[0038] The lifting component 31 in the lifting mechanism 3 also has various forms, see reference. Figure 1 and Figure 2 As shown, the lifting assembly 31 also uses a conveyor belt for transport. Specifically, the lifting assembly 31 includes a lifting frame 311, a lifting drive 314, lifting conveyor belt pulleys 312, and a lifting conveyor belt 313. The lifting frame 311 extends along a third direction and is mounted on the frame 1. Two lifting conveyor belt pulleys 312 are spaced apart along a third direction on the lifting frame 311 and connected by the lifting conveyor belt 313. One of the lifting conveyor belt pulleys 312 serves as the drive pulley and is connected to the lifting drive 314, which is a motor. The material tray 32 is detachably fixed to the lifting conveyor belt 313 so that it can move up and down along a third direction under the action of the lifting drive 314.

[0039] In this embodiment, to prevent the material tray 32 from moving excessively, the lifting mechanism 3 also includes a photoelectric switch. One of the material tray 32 and the lifting frame 311 is provided with a light receiver, and the other is provided with a light generator. When the light receiver and the generator are opposite each other, the lifting assembly 31 stops moving.

[0040] refer to Figures 4-6As shown, the lifting mechanism 3 also includes a telescopic component 33. The telescopic component 33 can drive the material tray 32 to move along the first direction to avoid the translation frame 211 being too long and interfering with the lifting of the material tray 32. At the same time, it can also realize the rapid convergence of the material tray 32 and the material gripping component 23, further improving the loading and unloading efficiency. For example, the telescopic component 33 adopts a double stroke structure, specifically including a telescopic drive component 335, a telescopic seat plate 332, a lifting seat plate 331, a telescopic conveyor belt wheel 333, and a telescopic conveyor belt 334. The lifting seat plate 331 is set at the output end of the lifting component 31, that is, on the lifting conveyor belt 313 and is slidably connected to the lifting frame 311. The telescopic seat plate 332 is movably set on the lifting seat plate 331 along the first direction. The telescopic drive component 335 is installed on the lifting seat plate 331 and configured to drive the telescopic seat plate 332 to move along the first direction. Two telescopic conveyor belt pulleys 333 are spaced apart along a first direction and installed in mounting holes on the telescopic base plate 332, connected by a telescopic conveyor belt 334. The telescopic conveyor belt 334 is partially fixed to the lifting base plate 331, and the material tray 32 is fixed to the telescopic conveyor belt 334. When the telescopic drive member 335 drives the telescopic base plate 332 to move, the telescopic conveyor belt 334 is displaced relative to the telescopic base plate 332, thereby driving the material tray 32 mounted on the telescopic base plate 332 to move. In other words, under the driving action of the telescopic drive member 335 and the transmission action of the telescopic conveyor belt 334, the material tray 32 moves by twice the stroke of the telescopic drive member 335, resulting in high moving efficiency.

[0041] refer to Figure 4 As shown, the loading tray 32 includes a base 321 and limiting members 322. The base 321 is used to support the goods, and the limiting members 322 are disposed on the base 321 to limit the goods. The shape of the limiting members 322 varies depending on the shape of the goods. Taking a testing machine with rectangular goods as an example, the limiting members 322 are L-shaped, with two symmetrically positioned at opposite corners of the base 321. This allows the limiting members 322 to limit the four side walls of the goods, facilitating the feeding / unloading mechanism 2 to move above the goods according to a preset program to transfer them. Furthermore, the base 321 is divided into a main board and a mounting plate. The main board is connected to the telescopic conveyor belt 334, and the mounting plate is detachably disposed on the main board. The limiting members 322 are integrally formed with the mounting plate. When the specifications of the goods to be loaded / unloaded change, the position of the limiting members 322 can be adjusted by directly replacing the mounting plate, allowing the limiting members 322 to adapt to the specifications of the goods. Specifically, the mounting plate is plugged into the motherboard, which has at least one pin, and the mounting plate has a socket for the pin to be inserted.

[0042] When loading and unloading goods, the aforementioned automated loading and unloading rack first places the goods to be transferred to the rack 1 onto the loading tray 32 via the lifting mechanism 3. The lifting component 31 then moves the loading tray 32 to the corresponding rack layer. At the same time, the first translation component 21 and the second translation component 22 of the feeding and unloading mechanism 2 move the gripping component 23 to the top of the goods to be transferred from the rack 1 and grip the goods. The telescopic component 33 moves the loading tray 32 along the first direction toward the feeding and unloading mechanism 2. The feeding and unloading mechanism 2 also moves the gripping component 23 along the first direction toward the lifting mechanism 3. When the gripping component 23 moves above the loading tray 32, it transfers the goods on the gripping component 23 to the loading tray 32 and grips the goods on the loading tray 32. The loading tray 32 moves downward under the action of the lifting component 31. At the same time, the gripping component 23 moves under the action of the first translation component 21 and the second translation component 22 to transfer the goods onto the rack 1, thus completing the synchronous loading and unloading.

[0043] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
