Description

Technical Field

[0001] This utility model relates to the field of warehouse automation technology, and in particular to a warehouse changeover device. Background Technology

[0002] In modern manufacturing processes, EOL (End of Line) racks serve as crucial tools for product testing, assembly, and packaging, and their quantity and size are increasing with the continuous expansion of production scale. EOL racks are often designed for specific product specifications, and when the production line needs to switch to producing different models, EOL racks need to be redesigned. However, when multiple large-sized EOL racks exist simultaneously, their storage becomes a pressing problem that needs to be solved.

[0003] Traditional EOL rack storage methods mostly use flat placement, which not only takes up a lot of space but also cannot meet the production line's need for rapid EOL rack changeover. Moreover, when the production line needs to switch production models, workers often have to spend a lot of time manually pushing and pulling the EOL racks to the work area, which is not only inefficient but also poses safety risks.

[0030] The lifting drive unit moves the lifting frame up and down, aligning the height of the transport station with the height of the storage station where the test part (DPT) is located. A horizontal drive unit moves the transport component from the transport station to the storage station, placing the DPT on it. The horizontal drive unit then moves the transport component back from the storage station to the transport station. The lifting drive unit then moves the lifting frame vertically down, aligning the height of the transport station with the testing station. The transport component moves the DPT from the transport station to the testing station and then back to the transport station, completing the DPT changeover.

Detailed Implementation

[0039] 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 present 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, not the entire structure.

[0040] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

[0041] 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.

[0042] In the description of this embodiment, the terms "upper," "lower," "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 this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0043] like Figure 1-7 As shown, an embodiment of this utility model provides a storage conversion device, which includes a storage structure 3, a transport platform 2, and a test bench 1. The storage structure 3 has multiple storage stations arranged at intervals along the vertical direction. The transport platform 2 includes a lifting transport mechanism and a horizontal transport mechanism. The lifting transport mechanism includes a lifting drive unit 21 and a lifting frame 22 connected to the output end of the lifting drive unit 21. The horizontal transport mechanism includes a horizontal drive unit 23 installed on the lifting frame 22 and a transport component 24 connected to the output end of the horizontal drive unit 23. The lifting frame 22 has a transport station and is located between the test bench 1 and the storage structure 3 along a first horizontal direction. The test bench 1 has a test station. The lifting drive unit 21 can drive the lifting frame 22 to move up and down in the vertical direction so that the transport station can correspond to any storage station and to correspond to the test station. The horizontal drive unit 23 can drive the transport component 24 to move back and forth between the transport station and the storage station corresponding to the transport station along the first horizontal direction, and to move back and forth between the transport station and the test station.

[0044] The lifting frame 22 is positioned between the test bench 1 and the storage structure 3 along the first horizontal direction. The lifting drive unit 21 drives the lifting frame 22 to rise and fall vertically, so that the height of the transport station corresponds to that of the test station. The horizontal drive unit 23 drives the transport component 24 to move along the first horizontal direction to the test station, placing the test piece on the transport component 24. The horizontal drive unit 23 then drives the transport component 24 to transport the test piece to the transport station. The lifting drive unit 21 drives the lifting frame 22 to rise vertically, so that the height of the transport station corresponds to that of the storage station where the test piece is to be stored. The horizontal drive unit 23 drives the transport component 24 to transport the test piece from the transport station to the storage station and then back to the transport station, thus completing the storage of the test piece.

[0045] The lifting drive unit 21 drives the lifting frame 22 to rise and fall, so that the height of the transport station corresponds to the height of the storage station where the test part to be changed is located. The horizontal drive unit 23 drives the transport component 24 from the transport station to the storage station, placing the test part in the storage station on the transport component 24. The horizontal drive unit 23 drives the transport component 24 from the storage station back to the transport station. The lifting drive unit 21 drives the lifting frame 22 to fall vertically, so that the height of the transport station corresponds to the test station. The horizontal drive unit 23 drives the transport component 24 to transport the test part from the transport station to the test station and then back to the transport station, thus completing the change of the test part.

[0046] The storage structure 3 has multiple storage stations arranged at intervals along the vertical direction, which increases storage space and reduces storage area. The lifting drive unit 21 drives the lifting frame 22 to rise to different heights, and the horizontal drive unit 23 drives the transport component 24 to move back and forth between the transport station and the storage station, as well as between the test station and the transport station. This enables the storage and changeover of test components at different stations, reduces changeover time, and improves changeover efficiency.

[0047] For example, the handling platform 2 also includes a fixed support. The lifting drive unit 21 includes a servo motor, two sprockets, and a chain. The servo motor is mounted on the top of the fixed support. The two sprockets are arranged vertically at intervals and are rotatably connected to the fixed support. The output end of the servo motor is fixedly connected to one of the sprockets. The two sprockets are connected by a chain. The lifting frame 22 is fixedly mounted on the chain, and a counterweight is mounted on the chain. The plane containing the central axes of the two sprockets is a preset vertical plane. The lifting frame 22 and the counterweight are located on opposite sides of the preset vertical plane. The output end of the servo motor drives the sprockets to rotate, which in turn drives the chain transmission. The chain drives the lifting frame 22 to rise and fall vertically. The counterweight balances the load weight, preventing the lifting frame 22 from tilting during lifting and improving its stability.

[0048] Preferably, the servo motor is a dual-axis motor with two output ends. The fixed bracket is provided with chains, sprockets and counterweights on both sides along the second horizontal direction. Each output end is connected to the lifting frame 22 through a set of sprocket and chain structure. The chains on both sides of the fixed bracket can rise and fall synchronously to maintain the lifting balance of the lifting frame 22.

[0049] Furthermore, the test bench 1 includes a workbench 12 and an automatic locking mechanism. The automatic locking mechanism is installed on the workbench 12 and can selectively fix the test piece at the test station relative to the workbench 12, or enable the test piece at the test station to move relative to the workbench 12.

[0050] When the test piece (DPT) is in the test station, the automatic locking mechanism secures the DPT to the worktable 12; when the DPT needs to be moved away from the test station, the automatic locking mechanism allows the DPT to move relative to the worktable 12. The automatic locking mechanism can selectively fix or move the DPT relative to the worktable 12, ensuring that the DPT is stably placed on the worktable 12 without shifting.

[0051] Furthermore, the automatic locking mechanism includes a first driving member 13 and a locking member 14. The first driving member 13 is mounted on the worktable 12, and the output end of the first driving member 13 is connected to the locking member 14. The first driving member 13 can drive the locking member 14 to move back and forth between the locking position and the unlocking position along the second horizontal direction. When the locking member 14 is in the locking position, the locking member 14 is pressed against or inserted into the test piece at the test station. When the locking member 14 is in the unlocking position, the locking member 14 is separated from the test piece at the test station.

[0052] When the test piece (DPT) is in the testing station, the first driving member 13 drives the locking member 14 to press against the DPT along the second horizontal direction, fixing the DPT relative to the worktable 12 through the pressing force of the locking member 14. In other embodiments, the first driving member 13 can also drive the locking member 14 to insert into the DPT along the second horizontal direction, and the locking member 14 can restrict the movement of the DPT along the first horizontal direction. When the DPT needs to be removed from the testing station, the first driving member 13 drives the locking member 14 to separate from the DPT, so that the constraint force acting on the DPT disappears, that is, the DPT can move relative to the worktable 12.

[0053] like Figure 2 , 3As shown, the first driving member 13 and the locking member 14 are both arranged on both sides of the worktable 12 along the second horizontal direction. The first driving member 13 includes a cylinder, and the locking member 14 includes a positioning pin. The cylinder can drive the positioning pin to extend and retract along the second horizontal direction. When the test piece is in the test position, the cylinder drives the positioning pin to extend and insert into the through hole of the test piece. The positioning pin can restrict the movement of the test piece along the first horizontal direction to ensure that the test piece will not deviate. When the test piece needs to be moved away from the test position, the cylinder drives the positioning pin to retract so that the test piece can move relative to the worktable 12 along the first horizontal direction.

[0054] In other embodiments, the first driving member 13 may also drive the locking member 14 to press against the test piece at the test station. The locking member 14 is disposed on both sides of the workbench 12 along the second horizontal direction. The locking member 14 on each side can approach the locking member 14 on the other side to press and fix the test piece at the test station.

[0055] Furthermore, the test station 1 also includes a first detection unit, which is used to detect whether there is a test piece at the test station.

[0056] The warehouse changeover device also includes a controller, which is communicatively connected to the first detection unit. If there is a test piece at the testing station, the first detection unit can transmit a signal to the controller, which simultaneously transmits a signal to the first drive member 13. The first drive member 13 drives the locking member 14 to fix the test piece at the testing station relative to the worktable 12. If the test piece at the testing station needs to be moved, the first drive member 13 drives the locking member 14 to allow the test piece at the testing station to move relative to the worktable 12. For example, the first detection unit is a photoelectric sensor.

[0057] Furthermore, the test bench 1 also includes a plurality of first sliding rollers 15 rotatably mounted on the workbench 12. The plurality of first sliding rollers 15 are arranged at intervals along a first horizontal direction, and the test piece at the test station is supported by the plurality of first sliding rollers 15.

[0058] When the test piece travels back and forth between the transport station and the test station, the heights of the transport station and the test station are corresponding. Multiple first sliding rollers 15 are rotatably installed on the worktable 12, which greatly reduces the frictional resistance between the test piece and the worktable 12. The test piece can travel back and forth between the transport station and the test station with only a small force, ensuring that the test piece moves smoothly between the transport station and the test station.

[0059] Furthermore, the upper surface of the transport member 24 is provided with a positioning member 26, which is used to be inserted vertically into the test piece supported by the transport member 24.

[0060] Specifically, one of the positioning element 26 and the part to be tested has a positioning groove, and the other has a positioning protrusion that cooperates with the positioning groove.

[0061] For example, the positioning member 26 has a positioning protrusion, and the test piece has a positioning groove. During the transport of the test piece by the transport member 24, the positioning protrusion of the positioning member 26 is inserted into the positioning groove of the test piece, and the outer wall of the positioning protrusion contacts the inner wall of the positioning groove. During the movement of the transport member 24, the positioning protrusion provides a force to the test piece, thereby driving the test piece to move together, facilitating the movement of the test piece from the testing station to the transport station. In other embodiments, the test piece has a positioning protrusion, and the positioning member 26 has a positioning groove.

[0062] Furthermore, the test platform 1 is provided with a first limiting member 11 at one end away from the storage structure 3 along the first horizontal direction. The first limiting member 11 can abut against the test piece at the test station along the first horizontal direction, which can prevent the test piece from falling off the test station due to the rotation of the first sliding roller 15 when the automatic locking mechanism malfunctions or fails.

[0063] Furthermore, the first limiting member 11 has a first position and a second position. When the first limiting member 11 is in the first position, the first limiting member 11 can abut against the test piece in the test station along the first horizontal direction. When the first limiting member 11 is in the second position, the first limiting member 11 is not higher than the upper surface of the worktable 12.

[0064] The first limiting member 11 can switch between a first position and a second position. When the test piece is at the testing station, the first limiting member 11 is switched to the first position, where it abuts against the test piece along a first horizontal direction, blocking and limiting its movement and preventing it from falling off the testing station. When the test piece needs to be moved away from the testing station along the side away from the storage structure 3, the first limiting member 11 is switched to the second position, allowing it to slide directly off the workbench 12, facilitating the inspection and maintenance of the test piece by the operators.

[0065] like Figure 2 As shown, the first limiting member 11 is a baffle, and two are arranged at intervals along the first horizontal direction.

[0066] Furthermore, such as Figure 4 , 5 As shown, the lifting frame 22 includes a frame 221 and two support platforms 222 arranged at intervals along a second horizontal direction on the frame 221. The support platforms 222 are used to support the test piece in the transport station. A first transport channel is formed between the two support platforms 222 along a first horizontal direction. The transport piece 24 can enter and exit the first transport channel along the first horizontal direction. The upper surface of the transport piece 24 is at the same height as the upper surface of the support platform 222.

[0067] The transport component 24 is located in the first transport channel formed between the two support platforms 222. It enters and exits the first transport channel in the first horizontal direction, saving space. The transport component 24 will not interfere with the support platform 222, making it convenient for the transport component 24 to transport the test piece back and forth between the test station and the transport station, as well as back and forth between the transport station and the storage station.

[0068] Furthermore, two transport components 24 are arranged at intervals along the second horizontal direction, and the minimum interval between the two transport components 24 along the second horizontal direction is less than the maximum length of the test piece in the second horizontal direction. The same test piece is transported by the two transport components 24, ensuring that the test piece can be placed on the two transport components 24, and the two transport components 24 drive the test piece back and forth between different workstations.

[0069] For example, a single horizontal drive unit 23 drives two transport components 24 to reciprocate along a first horizontal direction via a transmission shaft, saving on the number of drive units and reducing costs. The synchronous movement of two transport components 24 spaced apart improves the load-bearing capacity of the test piece, thereby extending the service life of the transport components 24. In other embodiments, three or more transport components 24 may also be spaced apart along a second horizontal direction.

[0070] It should be noted that there are many ways to convert rotational motion into translational motion in the existing technology, such as the gear and rack structure, which will not be introduced here.

[0071] Furthermore, the transport platform 2 also includes two rolling components 25 arranged at intervals along the second horizontal direction. The support platform 222 is located between the two rolling components 25 along the second horizontal direction. The rolling component 25 includes at least two rolling elements arranged at intervals along the first horizontal direction. The axis of the rolling elements is vertical. The rolling elements are rotatably connected to the lifting frame 22. The rolling elements can contact the test piece being transported to or away from the transport station.

[0072] When the test piece is in the transport station, it is in contact with the rolling element. The movement of the test piece will cause the rolling element to rotate, which can reduce the frictional resistance of the test piece when it moves in the transport station, ensuring that the test piece moves smoothly to or away from the transport station and is less prone to skewing.

[0073] For example, the rolling assembly 25 includes two rolling elements that rotate synchronously, reducing the frictional resistance of the test piece when it moves at the transport station, and also saving on the cost of the number of rolling elements.

[0074] Furthermore, such as Figure 5 As shown, the lifting and conveying mechanism also includes a second detection unit 27, which is used to detect whether there is a part to be tested at the conveying station.

[0075] The second detection unit 27 is communicatively connected to the controller. The second detection unit 27 can detect whether there is a workpiece to be tested at the handling station, and can transmit signals to the controller in real time, facilitating real-time monitoring of the workpiece's arrival status by staff. For example, the second detection unit 27 is a photoelectric sensor.

[0076] Furthermore, the storage structure 3 includes a storage rack 32 and an automatic positioning mechanism. The automatic positioning mechanism is installed on the storage rack 32 and can selectively fix the test piece in the storage position relative to the storage rack 32, or enable the test piece in the storage position to move relative to the storage rack 32.

[0077] When the test piece (DPT) is in the storage station, the automatic positioning mechanism secures the DPT to the storage rack 32; when the DPT needs to be moved from the storage station, the automatic positioning mechanism allows the DPT to move relative to the storage rack 32. The automatic positioning mechanism can selectively fix or move the DPT relative to the storage rack 32, ensuring that the DPT in the storage station is stably placed on the storage rack 32 without shifting.

[0078] Furthermore, the automatic positioning mechanism includes a second drive member 33 and a positioning hook 34. The second drive member 33 is mounted on the storage rack 32, and the output end of the second drive member 33 is connected to the positioning hook 34. The second drive member 33 can drive the positioning hook 34 to rotate, so that the positioning hook 34 moves back and forth between the hook position and the unhooked position. When the positioning hook 34 is in the hook position, the positioning hook 34 hooks onto the test piece in the storage station. When the positioning hook 34 is in the unhooked position, the positioning hook 34 is located on one side or below the test piece in the storage station in the second horizontal direction and is separated from the test piece in the storage station.

[0079] The positioning hook 34 can switch between a hook position and a contact hook position. When the test piece is in the storage station, the second drive unit 33 drives the positioning hook 34 to rotate, switching it to the hook position. The hooking force of the positioning hook 34 fixes the test piece relative to the storage rack 32. When the test piece needs to be moved from the storage station, the second drive unit 33 drives the positioning hook 34 to rotate, switching it to the contact hook position. This removes the constraint force acting on the test piece, allowing it to move relative to the storage rack 32.

[0080] like Figure 6 As shown, the storage rack 32 has five layers. Each layer of the storage rack 32 has two support structures arranged at intervals along the second horizontal direction. Each support structure is equipped with a positioning hook 34. Each layer of the storage rack 32 has two positioning hooks 34, which can improve the stability of the test piece in the storage position.

[0081] For example, the second driving member 33 includes a tilting cylinder. The tilting cylinder extends and retracts to rotate the positioning hook 34. When the test piece is in the storage position, the tilting cylinder retracts, causing the positioning hook 34 to rotate and hook the test piece, ensuring that the test piece does not shift. When the test piece needs to be moved from the storage position, the tilting cylinder extends, causing the positioning hook 34 to rotate in the opposite direction so that the test piece is unhooked and can move relative to the storage rack 32. In other embodiments, the second driving member 33 may also drive the positioning pin to be inserted into the through hole of the test piece in the storage position along the first horizontal direction.

[0082] Furthermore, the test bench 1 has a second transport channel that runs through the first horizontal direction, and the storage rack 32 has a third transport channel that runs through the first horizontal direction. One end of the first transport channel in the first horizontal direction is directly opposite to and connected to the second transport channel in the first horizontal direction, and the other end of the first transport channel in the first horizontal direction is directly opposite to and connected to the third transport channel in the first horizontal direction.

[0083] The first transport channel is directly opposite and connected to the second and third transport channels in the first horizontal direction. During the process of transporting the component 24 back and forth between the transport station and the test station, and back and forth between the transport station and the storage station, the transporting component 24 can move to the bottom of the test piece. The lifting drive unit 21 drives the lifting frame 22 to lift the test piece in the test station or storage station in the vertical direction. Then, the horizontal drive unit 23 drives the transporting component 24 to move in the first horizontal direction to the transport station, thereby completing the storage and transformation of the test piece.

[0084] For example, a third transport channel is formed between the two support structures, extending along the first horizontal direction.

[0085] Furthermore, the storage structure 3 also includes a plurality of second sliding rollers 35 rotatably mounted on the storage rack 32. The test piece in the storage station is supported by the plurality of second sliding rollers 35, and the plurality of second sliding rollers 35 are arranged at intervals along the first horizontal direction.

[0086] When the test piece travels back and forth between the handling station and the storage station, the handling station and the storage station are at the same height. Multiple second sliding rollers 35 are rotatably installed on the storage rack 32, which greatly reduces the frictional resistance between the test piece and the storage rack 32. The test piece can travel back and forth between the handling station and the storage station with only a small force, ensuring that the test piece moves smoothly between the handling station and the storage station.

[0087] Since the workbench 12 is equipped with multiple first sliding rollers 15, the lifting frame 22 is equipped with a rolling assembly 25, and the storage rack 32 is equipped with multiple second sliding rollers 35, the positioning component 26 can provide a small force to the test piece to enable the test piece to move between the testing station and the handling station, as well as between the handling station and the storage station, thereby enabling the pick-up and drop-off of the test piece.

[0088] Furthermore, such as Figure 7 As shown, the storage rack 32 also includes a third detection unit 36, which is used to detect whether there is a test piece at the storage station.

[0089] The third detection unit 36 ​​is communicatively connected to the controller. If there is a device under test (DUT) at the storage station, the third detection unit 36 ​​can transmit a signal to the controller, which simultaneously transmits a signal to the second drive unit 33. The second drive unit 33 drives the positioning hook 34 to rotate so that it hooks onto the DUT at the storage station. If the DUT at the storage station needs to be removed, the second drive unit 33 drives the positioning hook 34 to rotate in the opposite direction so that it removes the DUT from the storage station. For example, the third detection unit 36 ​​is a photoelectric sensor.

[0090] Furthermore, the storage structure 3 is provided with a second limiting member 31 at one end away from the test station 1 along the first horizontal direction. The second limiting member 31 can abut against the test piece in the storage station along the first horizontal direction, which can prevent the test piece from falling off the storage station due to the rotation of the second sliding roller 35 when the automatic positioning mechanism malfunctions or fails.

[0091] For example, the second limiting member 31 is a baffle, and two are arranged at intervals along the second horizontal direction on each layer of storage rack 32.
