[0067] The following specific embodiments will further illustrate this application in conjunction with the above-described accompanying drawings. Detailed Implementation

[0068] The following specific embodiments are exemplary and not limiting, and are intended to provide a basic understanding of this application, and are not intended to identify key or decisive elements of this application or limit the scope of protection. As long as there is no structural conflict, the technical features mentioned in the various embodiments can be combined in any manner.

[0069] When a component is considered to be "located" on another component, it can be directly on the other component or may also be interspersed with other components. When a component is considered to be "connected" to another component, it can be directly connected to the other component or may also be interspersed with other components.

[0070] It is understandable that the term "perpendicular" is used to describe an ideal state between two components. In actual production or use, two components can exist in a state that is approximately perpendicular or equal to each other. For example, combined with numerical description, perpendicularity can refer to the angle between two straight lines within the range of 90° ± 10°, the dihedral angle between two planes within the range of 90° ± 10°, or the angle between a straight line and a plane within the range of 90° ± 10°. The two components described as "perpendicular" do not have to be absolutely straight lines or planes; they can be approximately straight lines or planes. From a macroscopic perspective, if the overall direction of extension is a straight line or plane, the component can be considered a "straight line" or "plane".

[0071] Unless otherwise defined, the term "multiple" in this document, when used to describe the number of components, specifically means that the component is two or more.

[0072] The following describes some embodiments of this application in detail with reference to the accompanying drawings.

[0073] Please see Figure 1This application provides a transfer device 100 for docking with a first track 101 and a second track (not shown) located at different heights along the direction of gravity. Both the first track 101 and the second track are used to transport a carrier 200, which is used to place products. The transfer device 100 includes a frame 10, a temporary storage component 20, a material handling component 30, and a material transfer component 40. The temporary storage component 20 is connected to the frame 10 and includes a first storage component 21 and a second storage component 22. The first storage component 21 is used to place the carrier 200 carrying qualified products, and the second storage component 22 is used to place the carrier 200 carrying unqualified products. The material handling component 30 and the material transfer component 40 are connected to the frame 10. Optionally, the first track 101 is located above the second track.

[0074] When the carrier 200 moves from the first track 101 to the second track, the picking component 30 moves above the first track 101 and picks up the carrier 200 from the first track 101. The transfer component 40 is used to receive the carrier 200 picked up by the picking component 30. When the carrier 200 carries defective products, the transfer component 40 is used to move the carrier 200 to the second storage unit 22. When the carrier 200 carries qualified products, the transfer component 40 is used to move the carrier 200 to the first storage unit 21 or the second track.

[0075] When the carrier 200 is transferred from the second track to the first track 101, the transfer component 40 is used to receive the carrier 200 on the second track. When the carrier 200 carries defective products, the transfer component 40 is used to move the carrier 200 to the second storage unit 22. When the carrier 200 carries qualified products, the transfer component 40 is used to move the carrier 200 to the first storage unit 21 or the transfer component 40 is used to move the carrier 200 to the picking component 30. The picking component 30 is used to move the carrier 200 above the first track 101 and place it on the first track 101.

[0076] This application uses the frame 10, temporary storage component 20, material handling component 30 and material transfer component 40 to realize the transfer of the carrier 200 between the first track 101 and the second track, and uses the first storage component 21 and the second storage component 22 to classify unqualified products, improve transfer efficiency, and thus improve overall production efficiency.

[0077] In some embodiments, during the transfer of the carrier 200 from the first track 101 to the second track, when the next workstation needs a product, the transfer component 40 directly moves the carrier 200 to the second track, and then moves the carrier 200 to the next workstation via the second track. When the next workstation does not need a product temporarily, the transfer component 40 directly moves the carrier 200 to the first storage unit 21 for temporary storage, reducing the impact on the subsequent transfer of other carriers 200 and improving transfer efficiency.

[0078] In some embodiments, during the transfer of the carrier 200 from the second track to the first track 101, when the next workstation needs a product, the transfer component 40 moves to the picking component 30. The picking component 30 moves the carrier 200 above the first track 101 and places it on the first track 101, then moves the carrier 200 to the next workstation via the first track 101. When the next workstation does not need a product temporarily, the transfer component 40 directly moves the carrier 200 to the first storage component 21 for temporary storage, reducing the impact on the subsequent transfer of other carriers 200 and improving transfer efficiency.

[0079] Please see Figure 2 In some embodiments, the frame 10 includes a fixed support 11, a lifting support 12, and a lifting power component 13. The lifting support 12 is connected to the fixed support 11, and the lifting power component 13 is connected to both the fixed support 11 and the lifting support 12. The lifting power component 13 drives the lifting support 12 to rise or fall relative to the fixed support 11. When the transfer device 100 is not in use, the lifting support 12 is located within the fixed support 11, reducing the space occupied and facilitating its movement between workstations requiring transfer. When the transfer device 100 is in use, the lifting power component 13 drives the lifting support 12 to rise relative to the fixed support 11 and maintains this raised state. Since the passageways between production lines in the workshop are small and personnel move around, driving the lifting support 12 to rise relative to the fixed support 11 via the lifting power component 13 allows for the use of the space above to connect to the first track 101, which helps save space. Optionally, the height to which the lifting support 12 is raised is at least greater than 2 meters.

[0080] In some embodiments, the lifting power component 13 includes a power component 131, a lead screw 132, and a slider 133. The power component 131 is connected to the lead screw 132, the slider 133 is connected to the lead screw 132, and the lifting bracket 12 is connected to the slider 133. The power component 131 drives the lead screw 132 to rotate, causing the slider 133 to move on the lead screw 132, thereby driving the lifting bracket 12 to rise and fall.

[0081] Please see Figure 1 and Figure 3 In some embodiments, the first storage component 21 includes a first sidewall 211 and a second sidewall 212 disposed opposite to each other. The first sidewall 211 is provided with a plurality of first receiving slots 2111, and the second sidewall 212 is provided with a plurality of second receiving slots 2121. The first receiving slots 2111 and the second receiving slots 2121 are used to receive the opposite sides of the carrier 200.

[0082] In some embodiments, the first storage component 21 includes a first top wall 213 and a first bottom wall 214 disposed opposite to each other. The first top wall 213 is detachably connected to the first side wall 211 and the second side wall 212, and the first bottom wall 214 is detachably connected to the first side wall 211 and the second side wall 212.

[0083] In some embodiments, the temporary storage component 20 includes a first support wall 23 and a second support wall 24 disposed opposite to each other, and a first bottom wall 214 connects the first support wall 23 and the second support wall 24 to support the first storage component 21.

[0084] In some embodiments, the first support wall 23 and the second support wall 24 are provided with a synchronous belt for conveying, and the first bottom wall 214 is provided on the synchronous belt to facilitate the loading and unloading of the first storage component 21 in cooperation with an external trolley.

[0085] In some embodiments, the temporary storage assembly 20 includes a moving drive 25 and a connecting frame 26. The moving drive 25 is connected to the connecting frame 26, a first storage component 21 is connected to the connecting frame 26, and a second storage component 22 is connected to the connecting frame 26. The first storage component 21 and the second storage component 22 are stacked along the direction of gravity. The moving drive 25 drives the connecting frame 26 to move, and the connecting frame 26 drives the first storage component 21 and the second storage component 22 to move along a first direction X, facilitating the transfer assembly 40 to place the carrier 200 into or remove it from the first storage component 21 and the second storage component 22. The first direction X is the direction of gravity.

[0086] In some embodiments, the temporary storage assembly 20 includes an adjusting member 27 disposed on the connecting frame 26. The adjusting member 27 connects the first support wall 23 and the second support wall 24, and is used to adjust the distance between the first support wall 23 and the second support wall 24, thereby adjusting the distance between the first side wall 211 and the second side wall 212, to facilitate adaptation to carriers 200 of different sizes and improve practicality. Optionally, the adjusting member 27 includes a combination of a motor and a lead screw.

[0087] In some embodiments, the structure of the second storage component 22 is the same as that of the first storage component 21.

[0088] In some embodiments, the second storage member 22 is connected to another adjustment member 27 to facilitate adaptation to carriers 200 of different sizes and improve practicality.

[0089] Please see Figure 1 In some embodiments, the material handling assembly 30 includes a telescopic member 31 and a gripper 32. The telescopic member 31 is fixedly connected to the lifting bracket 12, and the gripper 32 is connected to the telescopic member 31. The telescopic member 31 drives the gripper 32 to extend along the second direction Y, so that the gripper 32 is positioned above the first track 101. The gripper 32 moves toward the first track 101 and grips the carrier 200. The first direction X is perpendicular to the second direction Y.

[0090] In some embodiments, when the telescopic member 31 is in the retracted state, the telescopic member 31 and the gripper 32 can be housed inside the fixed bracket 11, which helps to reduce the space occupied.

[0091] Please see Figures 4 to 6 In some embodiments, the material transfer assembly 40 includes a lifting member 41 and a carrier member 42. The lifting member 41 connects the lifting bracket 12 and the carrier member 42. The lifting member 41 drives the carrier member 42 to move along the first direction X. The carrier member 42 is used to support the carrier 200.

[0092] In some embodiments, the lifting member 41 includes a lifting drive member 411 fixed to the top of the lifting bracket 12, a conveyor belt 412 connected to the lifting drive member 411, and a connecting bracket 413 connected to the conveyor belt 412. The connecting bracket 413 is slidably connected to the lifting bracket 12 and is fixedly connected to the carrier member 42. The lifting drive member 411 drives the conveyor belt 412 to move, the conveyor belt 412 drives the connecting bracket 413 to move, and the connecting bracket 413 drives the carrier member 42 to move.

[0093] When the carrier 200 moves from the first track 101 to the second track, the telescopic member 31 drives the gripper 32 to extend along the second direction Y, positioning the gripper 32 above the first track 101. The gripper 32 moves towards the first track 101 and grips the carrier 200. Then, the telescopic member 31 retracts, positioning the gripper 32 above the support member 42. The lifting drive member 411 raises the support member 42, and the gripper 32 lowers, placing the carrier 200 on the support member 42. The lifting drive member 411 then continues to move the carrier to the height of the second track. Depending on the requirements of the next workstation, the carrier 200 is placed on the second track or the first storage member 21. When a product is defective, the moving drive member 25 drives the connecting frame 26 to move. The connecting frame 26 moves the first storage member 21 and the second storage member 22 along the first direction X, aligning the height of the second storage member 22 with the height of the support member 42. The support member 42 then places the carrier 200 on the second storage member 22.

[0094] When the carrier 200 is transferred from the second track to the first track 101, the carrier 42 receives the carrier 200 from the second track and places the carrier 200 on the first track 101 or the first storage unit 21 according to the needs of the next work station. When it is necessary to place the carrier 200 on the first track 101, the lifting drive 411 drives the carrier 42 to rise, the gripper 32 grips the carrier 200, and the telescopic member 31 drives the gripper 32 to extend along the second direction Y, so that the gripper 32 is above the first track 101, the gripper 32 moves toward the first track 101, and places the carrier 200 on the first track 101.

[0095] In some embodiments, the carrier 42 includes a receiving portion 421 and a push-pull portion 422. The receiving portion 421 is used to support the carrier 200, and the push-pull portion 422 is used to move the carrier 200 to the first storage member 21, the second storage member 22, or the second track. The push-pull portion 422 is also used to move the carrier 200 in the first storage member 21 to the receiving portion 421.

[0096] In some embodiments, the receiving part 421 includes a first connecting wall 4211, a second connecting wall 4212, and a mounting plate 4213. The mounting plate 4213 is fixed to the connecting bracket 413. The first connecting wall 4211 and the second connecting wall 4212 are disposed opposite to each other and connected to the mounting plate 4213. The first connecting wall 4211 and the second connecting wall 4212 are provided with a timing belt for conveying the carrier 200.

[0097] In some embodiments, the carrier 41 includes an adjusting member 43, which connects to a first connecting wall 4211 and a second connecting wall 4212. The adjusting member 43 drives the first connecting wall 4211 and the second connecting wall 4212 to move towards or away from each other along a third direction Z, facilitating adaptation to carriers 200 of different sizes and improving practicality. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0098] In some embodiments, the first connecting wall 4211 is slidably connected to the mounting plate 4213, and the second connecting wall 4212 is slidably connected to the mounting plate 4213, which facilitates improving the smoothness of the first connecting wall 4211 and the second connecting wall 4212 moving towards or away from each other.

[0099] In some embodiments, the adjusting member 43 includes a combination of a motor and a lead screw.

[0100] In some embodiments, the push-pull portion 422 includes a first moving member 4221, a second moving member 4222, a lifting member 4223, and a clamping member 4224. The first moving member 4221 is fixed to the mounting plate 4213. The second moving member 4222 is connected to the first moving member 4221, the lifting member 4223 is connected to the second moving member 4222, and the clamping member 4224 is connected to the lifting member 4223. The lifting member 4223 drives the clamping member 4224 to move up and down. The clamping member 4224 is used to clamp the carrier 200. The first moving member 4221 and the second moving member 4222 drive the clamping member 4224 to move toward or away from the first storage member 21 or the second storage member 22.

[0101] When the carrier 200 is placed in the first storage unit 21, the lifting member 4223 drives the clamping member 4224 to rise, so that the clamping member 4224 is at the same height as the carrier 200. The second moving member 4222 drives the clamping member 4224 to move, so that the clamping member 4224 clamps the carrier 200. The first moving member 4221 drives the second moving member 4222 to move toward the first storage unit 21. After the second moving member 4222 gets close to the first storage unit 21, the second moving member 4222 further drives the clamping member 4224 to move, pushing the carrier 200 into the first receiving slot 2111 and the second receiving slot 2121.

[0102] When the carrier 200 is removed from the first storage unit 21, the first moving member 4221 drives the second moving member 4222 to move toward the first storage unit 21. After the second moving member 4222 approaches the first storage unit 21, the second moving member 4222 further drives the clamping member 4224 to move. The lifting member 4223 drives the clamping member 4224 to rise, so that the clamping member 4224 is at the same height as the carrier 200. The second moving member 4222 drives the clamping member 4224 to move, so that the clamping member 4224 clamps the carrier 200. Then the first moving member 4221 and the second moving member 4222 drive the carrier 200 to move to the first connecting wall 4211 and the second connecting wall 4212.

[0103] In some embodiments, when the carrier 200 is placed in the first storage member 21 or when the carrier 200 is removed from the first storage member 21, the synchronous belts on the first connecting wall 4211 and the second connecting wall 4212 maintain the same direction of transmission as the material taking and discharging actions, which facilitates placing the carrier 200 in the first storage member 21 or facilitating the removal of the carrier 200 from the first storage member 21.

[0104] When the aforementioned transfer device 100 is in use, as the carrier 200 transfers from the first track 101 to the second track, the telescopic member 31 drives the gripper 32 to extend along the second direction Y, positioning the gripper 32 above the first track 101. The gripper 32 moves towards the first track 101 and grips the carrier 200. Then, the telescopic member 31 retracts, positioning the gripper 32 above the support member 42. The lifting drive member 411 raises the support member 42, and the gripper 32 lowers, placing the carrier 200 on the support member 42. Then, the lifting drive member 411 continues to move the carrier to the height of the second track. Depending on the needs of the next workstation, the carrier 200 is placed on the second track or the first storage member 21. When the product is defective, the moving drive 25 drives the connecting frame 26 to move, and the connecting frame 26 drives the first storage component 21 and the second storage component 22 to move along the first direction X, so that the height of the second storage component 22 is consistent with the height of the carrier 42, and the push-pull part 422 places the carrier 200 on the second storage component 22.

[0105] When the carrier 200 transfers from the second track to the first track 101, the receiving part 421 receives the carrier 200 from the second track and, according to the needs of the next workstation, places the carrier 200 on the first track 101 or the first storage unit 21. When it is necessary to place the carrier 200 on the first track 101, the lifting drive 411 drives the bearing 42 to rise, the gripper 32 grips the carrier 200, and the telescopic part 31 drives the gripper 32 to extend along the second direction Y, so that the gripper 32 is above the first track 101, the gripper 32 moves toward the first track 101, and places the carrier 200 on the first track 101. When it is necessary to place the carrier 200 on the first storage unit 21, the pushing and pulling part 422 places the carrier 200 on the first storage unit 21.

[0106] Understandably, the previous workstation provides a signal to determine whether a product is qualified, and the transfer component 40 receives and executes the signal.
