Description

Technical Field

[0001] This application relates to the field of mechanical equipment technology, and more particularly to a conveying mechanism. Background Technology

[0002] During vehicle assembly, the assembly platform is typically designed to be elevated above the ground. Therefore, parts to be assembled need to be placed on higher shelves so that operators can easily access them, thus improving assembly efficiency. Transporting parts from lower levels to higher shelves is usually done manually, which is time-consuming and labor-intensive. Utility Model Content

[0003] The purpose of this application is to provide a transportation mechanism that aims to solve the problem of how to improve the efficiency of object transportation.

[0004] A conveying mechanism is provided, including a slide rail assembly and a lifting device. The slide rail assembly includes a first slide rail and a second slide rail, both of which are inclined. The first and second slide rails are spaced apart along the height direction, with the height of the second slide rail being higher than that of the first slide rail. A first end of the first slide rail is positioned opposite to and away from the first end of the second slide rail, while a second end of the first slide rail is positioned opposite to and close to the second end of the second slide rail.

[0005] The lifting device includes a lifting frame, a power unit, and a first storage tray. The lifting frame is disposed on a first side of the slide rail assembly, the first side being the side where the first end of the first slide rail and the first end of the second slide rail are located. The power unit drives the lifting frame to move up and down between the first end of the first slide rail and the first end of the second slide rail. The first storage tray is rotatably disposed on the lifting frame. A first baffle is provided at the end of the first storage tray away from the slide rail assembly, and a first stop is provided at the other end of the first storage tray near the slide rail assembly.

[0006] When the lifting frame is in the lowered state, the lifting frame is located at the first end of the first slide rail. One end of the first storage tray is tilted downward under the gravity of the first baffle. The other end of the first storage tray is arranged opposite to the first end of the first slide rail, so that an object located on the first slide rail slides along the first slide rail to the first storage tray under its own gravity and stops on the first storage tray under the stop of the first baffle.

[0007] When the lifting frame is in the raised state, it is located at the first end of the second slide rail. The first stop, supported by the second slide rail, causes the other end of the first storage tray to tilt downwards. The other end of the first storage tray is positioned opposite the first end of the second slide rail, allowing objects on the first storage tray to slide onto the second slide rail under gravity.

[0008] Optionally, the conveying mechanism further includes: a fixed frame and a first blocking device, the first blocking device being disposed at the first end of the first slide rail and located on the side of the first slide rail away from the second slide rail. The first blocking device includes: a first body portion, a first blocking portion, a second blocking portion, and a first elastic member. The first end of the first body portion extends toward the lifting frame, and the first end of the first body portion is closer to the lifting frame than the first end of the first slide rail. The first body portion is rotatably disposed on the fixed frame via a first pivot. The first blocking portion is located between the first end of the first body portion and the first pivot, and extends toward the first slide rail. The second blocking portion is located at the second end of the first body portion and extends toward the first slide rail. One end of the first elastic member is connected to the second end of the first body portion, and the other end of the first elastic member is connected to the fixed frame.

[0009] When the lifting frame is in the lowered state, the first blocking device is in the first blocking state. The first end of the first body portion is located below the lifting frame, and the first end of the first body portion is tilted downwards by the pressure of the lifting frame. The first blocking portion is located below the first slide rail, and at least a portion of the second blocking portion passes through the first slide rail to be located above the first slide rail.

[0010] When the lifting frame is in the raised state, the first blocking device is in the second blocking state. The second end of the first body portion moves downward under the elastic force of the first elastic member, and the first end of the first body portion is raised upward until the first body portion abuts against the first end of the first slide rail. At least a portion of the first blocking portion passes through the first slide rail to be located above the first slide rail, and the second blocking portion is located below the first slide rail.

[0011] Optionally, the first blocking device further satisfies at least one of the following: the first blocking portion is perpendicular to the first body portion; the second blocking portion is perpendicular to the first body portion; in the first blocking state, the first body portion is parallel to the horizontal plane; in the second blocking state, the first body portion is parallel to the first slide rail; or, the length of the first blocking portion is less than the length of the second blocking portion.

[0012] Optionally, the conveying mechanism further includes: a crash-proof storage box, in which the object is disposed, and the crash-proof storage box has an extension on at least one side along its circumference. Two adjacent crash-proof storage boxes contact each other through the extension to form a gap between them. The distance between the first blocking portion and the second blocking portion is equal to the projected distance of the crash-proof storage box in the extension direction of the first slide rail.

[0013] Optionally, the conveying mechanism further includes a fixed frame, with the power assembly disposed on top of the fixed frame. The power assembly includes a cylinder, a connecting rod, a pulley system, and a traction rope. The piston rod of the cylinder moves in a first direction. A first end of the connecting rod is connected to the piston rod of the cylinder. The pulley system is disposed between the connecting rod and the lifting frame. The traction rope is wound around the pulley system, with one end of the traction rope connected to the second end of the connecting rod and the other end of the traction rope connected to the lifting frame.

[0014] Optionally, the pulley assembly includes a first pulley and a second, third, fourth, and fifth pulley spaced apart along a second direction. The first pulley is located on the side of the connecting rod away from the cylinder along the first direction, and the second, third, fourth, and fifth pulleys are all located on the side of the first pulley closer to the lifting frame. The traction rope, after passing through the first pulley, splits into two paths: one path connects to one side of the lifting frame along the second direction via the second and third pulleys, and the other path connects to the other side of the lifting frame along the second direction via the fourth and fifth pulleys.

[0015] Optionally, the conveying mechanism further includes a venting switch, which is electrically connected to the cylinder. The venting switch is disposed on the second slide rail, and there is a preset distance between the venting switch and the first end of the second slide rail. As the object slides along the second slide rail, the venting switch is triggered, the cylinder is depressurized, and the lifting frame is lowered.

[0016] Optionally, the conveying mechanism further includes a first counterweight and a first rope, the first counterweight being suspended from the top of the fixed frame. One end of the first rope is connected to the lifting frame, and the other end of the first rope is connected to the first counterweight via the top of the fixed frame.

[0017] Optionally, the conveying mechanism further includes a sliding part and a first mating part, the sliding part being disposed on the lifting frame. The first mating part cooperates with the sliding part, and the lifting frame also moves within the first mating part via the sliding part during the lifting process.

[0018] Optionally, the transport mechanism further includes: a drop-off frame, a second storage tray, and a second counterweight. The drop-off frame is disposed on the second side of the slide rail assembly, the second side being the side where the second end of the first slide rail and the second end of the second slide rail are located. The second storage tray is rotatably disposed on the drop-off frame. The second counterweight is connected to the drop-off frame. The weight of the second counterweight is greater than the total weight of the drop-off frame and the second storage tray, and less than the total weight of the drop-off frame, the second storage tray, and the anti-collision storage box. The anti-collision storage box on the second slide rail slides to the second storage tray, and descends to the second end of the first slide rail under the action of the drop-off frame, and then returns to the first slide rail.

[0022] In the embodiments of this application, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of that feature.

[0023] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0024] "A and / or B" includes the following three combinations: A only, B only, and a combination of A and B.

[0025] In the embodiments of this application, "parallel," "perpendicular," and "equal" include the described situation and situations similar to the described situation, where the range of similarity is within an acceptable deviation range, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism can be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity can also be, for example, a deviation within 5°. "Equal" includes absolute equality and approximate equality, where the acceptable deviation range for approximate equality can be, for example, a difference between the two equals being less than or equal to 5% of either one.

[0026] To address the problems in related technologies, some embodiments of this application provide a transportation mechanism 100. For example... Figure 2 and Figure 3 As shown, the conveying mechanism 100 includes a slide rail assembly, which includes a first slide rail 10 and a second slide rail 20.

[0027] Both the first slide rail 10 and the second slide rail 20 are inclined. Along the first direction, the height of the first end of the first slide rail 10 is lower than the height of the second end of the first slide rail 10, and the height of the first end of the second slide rail 20 is higher than the height of the second end of the second slide rail 20.

[0028] The first slide rail 10 and the second slide rail 20 are spaced apart along the height direction, with the height of the second slide rail 20 being higher than the height of the first slide rail 10, i.e., the first slide rail 10 is located below the second slide rail 20. Along the height direction, the first end of the first slide rail 10 and the first end of the second slide rail 20 are positioned opposite each other and far apart, while the second end of the first slide rail 10 and the second end of the second slide rail 20 are positioned opposite each other and close together. However, this is not a limitation. Those skilled in the art will understand that in other embodiments, along the height direction, the first end of the first slide rail 10 and the first end of the second slide rail 20 may be positioned opposite each other and close together, while the second end of the first slide rail 10 and the second end of the second slide rail 20 may be positioned opposite each other and far apart.

[0029] like Figure 2 and Figure 3 As shown, the first tilt angle of the first slide rail 10 is θ1, and the second tilt angle of the second slide rail 20 is θ2. Here, the first tilt angle refers to the angle between the extension direction of the first slide rail 10 and the horizontal direction, and the second tilt angle refers to the angle between the extension direction of the second slide rail 20 and the horizontal direction. θ1 and θ2 can be the same or different, and this application does not impose any restrictions on this.

[0030] In some embodiments, the conveying mechanism 100 further includes a lifting device 30 configured to convey an object on the first slide rail 10 to the second slide rail 20.

[0031] In some embodiments, the lifting device 30 includes a power unit and a lifting frame 7, which is disposed on a first side of the slide rail assembly. The first side of the slide rail assembly refers to the side where the first end of the first slide rail 10 and the first end of the second slide rail 20 are located. The power unit is configured to raise the lifting frame 7 from the first end of the first slide rail 10 to the first end of the second slide rail 20, or to lower the lifting frame 7 from the first end of the second slide rail 20 to the first end of the first slide rail 10.

[0032] In some embodiments, the lifting frame 7 may include a base plate and a handle, or the lifting frame 7 may be a cuboid structure with an opening at the top, or the lifting frame 7 may use a cuboid structure with an opening at the top as the base plate and provide a handle above the opening. This application does not limit the structure of the lifting frame 7.

[0033] The lifting device 30 also includes a first storage tray 8, which is rotatably mounted on the lifting frame 7. For example, the first storage tray 8 can be rotatably mounted on a handle of the lifting frame 7, or on the side wall of the cuboid lifting frame 7. The first storage tray 8 has a first tilted state and a second tilted state. In the first tilted state, an object can slide onto the first storage tray 8; in the second tilted state, an object can slide off the first storage tray 8.

[0034] In some embodiments, such as Figure 1 and Figure 2 As shown, a first baffle 81 is provided at the first end of the first storage tray 8 away from the slide rail assembly. In the first tilted state, the first end where the first baffle 81 is located tilts downward to block and limit the object after it slides from the first slide rail 10 to the first storage tray 8, so as to prevent the object from sliding out of the first storage tray 8.

[0035] In some embodiments, a first stop 82 is provided at the second end of the first storage tray 8 near the slide rail assembly. In the second tilted state, the first stop 82, under the resistance of the second slide rail 20, causes the second end of the first storage tray 8 to tilt downward, so that the object can slide out of the first storage tray 8.

[0036] With the lifting frame 7 in the lowered state, it is located at the first end of the first slide rail 10. Under the gravity of the first baffle 81, the first storage tray 8 is in a first tilted state, that is, the first end of the first storage tray 8 away from the first slide rail 10 tilts downward and abuts against the lifting frame 7; the second end of the first storage tray 8 near the first slide rail 10 tilts upward and is positioned opposite to the first end of the first slide rail 10. This facilitates the sliding of objects on the first slide rail 10 to the first storage tray 8.

[0037] With the lifting frame 7 in the raised state, it is located at the first end of the second slide rail 20. With the first stop 82 blocking the second slide rail 20, the first storage tray 8 is in a second tilted state. The second end of the first storage tray 8 near the second slide rail 20 tilts downwards under the action of the first stop 82 until the second end of the first storage tray 8 abuts against the lifting frame 7. At this time, the first end of the first storage tray 8 is lifted upwards, and the second end of the first storage tray 8 is positioned opposite the second slide rail 20, thus facilitating the sliding of objects out of the first storage tray 8 and onto the second slide rail 20.

[0038] In some embodiments, the angle between the first storage tray 8 and the horizontal plane in the first tilted state is α1, and α1 can be equal to the tilt angle θ1 of the first slide rail 10. Of course, in some embodiments, α1 and θ1 can also be unequal, for example, |α1-θ1|≤15°. By limiting the range of the difference between α1 and θ1, the smoothness of the object sliding between the first slide rail 10 and the first storage tray 8 can be guaranteed.

[0039] The first storage tray 8, in its second tilted state, forms an angle α2 with the horizontal plane. α2 can be equal to the tilt angle θ2 of the second slide rail 20. Of course, in some embodiments, α2 and θ2 may not be equal; for example, |α2-θ2|≤15°. By limiting the range of the difference between α2 and θ2, the smoothness of the object sliding between the first storage tray 8 and the second slide rail 20 can be guaranteed.

[0040] In some embodiments, the conveying mechanism 100 further includes a mounting frame 60, a slide rail assembly disposed inside the mounting frame 60, and a power assembly disposed on top of the mounting frame 60.

[0041] In some embodiments, the power unit includes a cylinder 2, which provides power for the raising and lowering of the lifting frame 7 by intake and exhaust.

[0042] In some embodiments, the power assembly further includes a connecting rod 3, one end of which is connected to the piston rod of the cylinder 2. For example, when the cylinder 2 is intake, the piston rod retracts, causing the connecting rod 3 to contract, thereby causing the lifting frame 7 to rise; when the cylinder 2 is exhaust, the piston rod extends, causing the connecting rod 3 to extend, thereby causing the lifting frame 7 to fall. By providing the connecting rod 3, which indirectly drives the lifting frame 7, the stroke of the cylinder 2 can be increased.

[0043] In some embodiments, the power assembly further includes a pulley block 4, which is disposed on the side of the connecting rod 3 away from the cylinder 2 along a first direction. The pulley block 4 includes at least one pulley.

[0044] The power assembly also includes a traction rope 5, at least a portion of which is wound around the pulley block 4. A first end of the traction rope 5 is connected to the opposite end of the connecting rod 3, and a second end of the traction rope 5 is connected to the lifting frame 7.

[0045] It should be noted that the length of the traction rope 5 can be set according to requirements, so that the stroke of the power component can drive the lifting frame 7 to move between the first end of the first slide rail 10 and the first end of the second slide rail 20.

[0046] In some embodiments, such as Figure 5 As shown, the pulley block 4 may include a first pulley 401, and a second pulley 402, a third pulley 403, a fourth pulley 404 and a fifth pulley 405 spaced apart along a second direction. The first pulley 401 is located on the side of the connecting rod 3 away from the cylinder 2 along the first direction, and the second pulley 402, the third pulley 403, the fourth pulley 404 and the fifth pulley 405 are located on the side of the first pulley 401 near the lifting frame 7 along the height direction.

[0047] The first pulley 401 changes the direction of tension in the traction rope 5 from the horizontal to the vertical. After passing through the first pulley 401, the traction rope 5 splits into two paths: one path is fixed to one side of the lifting frame 7 along the second direction via the second pulley 402 and the third pulley 403, and the other path is fixed to the other side of the lifting frame 7 along the second direction via the third pulley 403 and the fourth pulley 404.

[0048] In this way, by setting traction ropes 5 on both sides of the lifting frame 7 along the second direction, the stability of the lifting frame 7 during the lifting process is improved.

[0049] Of course, the pulley block 4 can also include a movable pulley, which is fixedly installed with the lifting frame 7. The power unit drives the lifting frame 7 and the movable pulley to rise and fall together. In this way, the combination of the movable and fixed pulleys can save effort and help solve the problem of insufficient pulling force of the cylinder 2.

[0050] In some embodiments, the connecting rod 3 can also convert the linear motion of the piston rod of the cylinder 2 into rotational motion. The other end of the connecting rod 3 can be fixedly equipped with a wheel axle, and the first end of the traction rope can be connected to the wheel axle. In this way, the connecting rod 3 can drive the wheel axle to rotate, thereby enabling the traction rope 5 to reciprocate and wind, which helps to reduce the horizontal extension space of the traction rope 5. Because the space restriction on the traction rope 5 is reduced, it also facilitates the use stroke of the long traction rope 5.

[0051] Furthermore, the reduced space required for the traction rope 5 increases the available space for the cylinder 2 and connecting rod 3, providing them with a certain degree of freedom in their movement. This avoids the problem of limited stroke of the piston rod or connecting rod of cylinder 2 after setting cylinder 2 and connecting rod 3 in a preset position, thus helping to ensure the stability of the power assembly's operation.

[0052] In some embodiments, the conveying mechanism 100 further includes a first counterweight 70 and a first rope 701. The first counterweight 70 is fixedly connected to the lifting frame 7 via the first rope 701, and the first rope 701 passes through the top of the fixed frame 60, suspending the first counterweight 70 from the fixed frame 60. Thus, when the pulling force of the cylinder 2 is insufficient, the first counterweight can assist in the lifting process, thereby reducing the energy consumption of the power components. Furthermore, the first counterweight can also slow down the descent speed of the lifting frame 7 during its descent, thereby protecting the lifting frame 7.

[0053] In some embodiments, the conveying mechanism 100 further includes an air intake switch 1, which is electrically connected to the cylinder 2 and configured to control air intake into the cylinder 2. When the air intake switch 1 is turned on, air enters the cylinder 2, the piston rod of the cylinder 2 retracts, and the lifting frame 7 rises.

[0054] In some embodiments, the piston rod moves between a first target position and a second target position, the first target position corresponding to the lowering state of the lifting frame 7 and the second target position corresponding to the rising state of the lifting frame 7.

[0055] When the lifting frame 7 is in the lowered state, if the air intake switch 1 is turned on, the piston rod will retract from the second target position to the first target position, causing the lifting frame 7 to rise. When the piston rod retracts to the first target position, the lifting frame 7 reaches the rising position 9 (i.e., the second end of the second slide rail 20).

[0056] In some embodiments, when the lifting frame 7 reaches the rising position, the air intake switch 1 receives a first shut-off signal and automatically shuts off to allow the cylinder 2 to release air subsequently.

[0057] In some embodiments, the air intake switch 1 is fixed to the mounting bracket 60, the air intake switch 1 is electrically connected to the cylinder 2, and is located on the side of the lifting frame 7 away from the first slide rail 10, so that the operator can turn on the air intake switch 1.

[0058] In some embodiments, the conveying mechanism further includes a vent switch 6, which is electrically connected to the cylinder 2 and configured to control the venting of the cylinder 2. When the vent switch 6 is activated, the cylinder 2 is vented, the piston rod of the cylinder 2 extends, and the lifting frame 7 descends.

[0059] With the lifting frame 7 in the raised position, if the vent switch 6 is opened, the piston rod extends from the first target position to the second target position, and the lifting frame 7 descends under the action of gravity. When the piston rod extends to the second target position, the lifting frame 7 is in the lowered position (i.e., the first end of the first slide rail 10).

[0060] In some embodiments, when the lifting frame 7 reaches the lowering position, the venting switch 6 receives a second closing signal and automatically closes to allow the cylinder 2 to take in air again.

[0061] In some embodiments, the vent switch 6 is disposed on the second slide rail 20. After the lifting frame 7 rises to the corresponding position at the first end of the second slide rail 20, the object will slide from the first storage tray 8 to the second slide rail 20. During the process of the object sliding from the first end of the second slide rail 20 to the second end of the second slide rail 20, it will touch the vent switch 6, thereby realizing the automatic descent of the lifting frame 7.

[0062] In this way, by installing a vent switch 6 on the object's sliding path, the object slides out of the first storage tray 8 and passes through the vent switch 6. When the object touches the vent switch 6, the cylinder 2 releases air, causing the lifting frame 7 to descend, thus achieving the automatic return of the lifting frame 7.

[0063] In some embodiments, the vent switch 6 is positioned at a preset distance from the first end of the second slide rail 20. This utilizes the time difference between the object sliding off the first storage tray 8 and the vent switch being triggered to achieve a delayed descent of the lifting frame 7. This ensures that the lifting frame 7 descends only after the object has completely slid off the first storage tray 8, improving the operational stability of the conveying mechanism 100.

[0064] In some embodiments, the conveying mechanism 100 further includes a first blocking device 40 disposed at a first end of the first slide rail 10. The first blocking device 40 is configured to release objects one by one. That is, when the lifting frame 7 is in the lowered position, a preset number of objects are released onto the first storage tray 8; when the lifting frame 7 leaves the lowered position, the objects are restrained on the first slide rail 10 to prevent them from falling off the first slide rail 10.

[0065] In some embodiments, the first blocking device 40 includes a first body portion 41, which is rotatably disposed on the fixing frame 60. A first end of the first body portion 41 extends toward the lifting frame 7 and extends beyond the first end of the first slide rail 10, that is, the first end of the first body portion 41 is closer to the lifting frame 7 than the first end of the first slide rail 10. This facilitates contact between the first end of the first body portion 41 and the lifting frame 7.

[0066] In some embodiments, the first blocking device 40 further includes a first rotating shaft 45, and the first body part 41 is rotatably disposed on the fixed frame 60 via the first rotating shaft 45.

[0067] In some embodiments, the first blocking device 40 further includes a first blocking portion 42, which is disposed at a position near its first end of the first body portion 41. For example, the first blocking portion 42 is disposed between the first end of the first body portion 41 and the first rotating shaft 45, and the first end of the first slide rail 10 is closer to the lifting frame 7 relative to the first blocking portion 42.

[0068] In some embodiments, the first blocking device 40 further includes a second blocking portion 43, which is disposed at the second end of the first body portion 41.

[0069] In some embodiments, the first blocking device 40 further includes a first elastic member 44 disposed between the second end of the first body portion 41 and the fixing frame 60. The first elastic member 44 is configured to provide a downward pulling force toward the second end of the first body portion 41.

[0070] When the lifting frame 7 is in the lowered position, the blocking device 40 is in the first blocking state. At this time, the second blocking part 43 blocks objects on the rear side (i.e., the side away from the first end of the first slide rail 10). For example, the lifting frame 7 applies downward pressure to the first end of the first body part 41, causing the first end of the first body part 41 to tilt downwards, and moving the first blocking part 42 below the first slide rail 10, while the second blocking part 43 moves above the first slide rail 10. Objects located in front of the second blocking part 43 (i.e., the side near the first end of the first slide rail 10) can slide onto the first storage tray 8, while objects located behind the second blocking part 43 are blocked by the second blocking part 43 and remain on the first slide rail 10.

[0071] After the lifting frame 7 leaves the lowered position, the blocking device 40 is in the second blocking state. At this time, the first blocking part 42 blocks the rear anti-collision storage box 9. Exemplarily, the first elastic member 44 applies a downward pulling force to the second end of the first body part 41, causing the first end of the first body part 41 to lift upward and finally abut against the first end of the first slide rail 10. At this time, the first blocking part 42 moves above the first slide rail 10, and the second blocking part 43 moves below the first slide rail 10. Objects behind the second blocking part 43 can move to the front of the second blocking part 43 and be blocked by the first blocking part 42, so as to facilitate subsequent movement to the first storage tray 8.

[0072] In some embodiments, the transport mechanism 100 further includes a shock-proof storage box 9, in which the object is placed. This allows the object to be transported via the shock-proof storage box 9. The shock-proof storage box 9 protects the object from scratches or damage.

[0073] In some embodiments, the crash-proof storage box 9 has an extension on at least one side along the circumferential direction. Thus, two adjacent crash-proof storage boxes 9 abut against each other via at least one extension, creating a gap between them. This facilitates the second blocking part 43 passing through the gap to limit the movement of the rear crash-proof storage box 9.

[0074] For example, the anti-collision storage box 9 has extensions on both sides along its length. When the anti-collision storage box 9 is placed on the first slide rail 10, there is no need to distinguish between left and right directions, which facilitates the placement and use of the anti-collision storage box 9.

[0075] Alternatively, the anti-collision storage box 9 may have extensions on both sides along its length and both sides along its width. In this way, when the anti-collision storage box 9 is placed on the first slide rail 10, there is no need to distinguish between the length and width directions, further facilitating the placement and use of the anti-collision storage box 9.

[0076] Of course, in some embodiments, the extension can be provided only on one side of the impact-resistant storage box 9 along its length. This simplifies the structure of the impact-resistant storage box 9 and saves materials.

[0077] In some embodiments, such as Figure 4 As shown, the distance between the first blocking part 42 and the second blocking part 43 is L1, and the length of the anti-collision storage box 9 is A, where L1 = N × A, and N is a positive integer. In this way, the second blocking part 43 of the first blocking device 40 can extend above the first slide rail 10 and be accommodated in the gap between two adjacent anti-collision storage boxes 9, so as to effectively block the rear anti-collision storage box 9.

[0078] In some embodiments, the length of the first storage tray 8 is L2, where L2 ≥ L1, so that all objects released by the first blocking device 40 can be accommodated in the first storage tray 8.

[0079] In some embodiments, in the first blocking state, the first body portion 41 of the first blocking device 40 may be parallel to the extending direction of the first slide rail 10. In the second blocking state, the first body portion 41 of the first blocking device 40 may be located in the horizontal direction.

[0080] In some embodiments, the first blocking portion 42 is disposed perpendicular to the first body portion 41. Of course, in some embodiments, the first included angle between the first blocking portion 42 and the first body portion 41 can be set as needed, for example, the first included angle can be 80°, 85°, 95°, 100°, etc.

[0081] In some embodiments, the second blocking portion 43 is disposed perpendicular to the first body portion 41. Of course, in some embodiments, the second included angle between the second blocking portion 43 and the first body portion 41 can be set as needed, for example, the second included angle can be 80°, 85°, 95°, 100°, etc.

[0082] In some embodiments, the length of the first blocking portion 42 is less than the length of the second blocking portion 43, or the distance from the top of the first blocking portion 42 to the first body portion 41 is less than the distance from the top of the second blocking portion 43 to the first body portion 41. Thus, since the first slide rail 10 is inclined, providing a longer length for the second blocking portion 43 than the first blocking portion 42 helps ensure the blocking effect of the second blocking portion 43 on the rear anti-collision storage box 9.

[0083] like Figure 4 As shown, in the first blocking state, the first body part 41 of the first blocking device 40 is parallel to the extending direction of the first slide rail 10, and the first blocking part 42 and the second blocking part 43 are both perpendicular to the first body part 41. This arrangement allows the portion of the second blocking part 43 extending above the first slide rail 10 to be parallel to the side wall of the anti-collision storage box 9, thereby ensuring that the second blocking part 43 is subjected to force evenly and preventing damage due to concentrated force.

[0084] Therefore, in some embodiments of this application, the first blocking part 42 and the second blocking part 43 of the first blocking device 40 are designed by lever principle and precise calculation of projection size. The transition between the first blocking state and the second blocking state is achieved by the change of pressure at the first end of the first body part 41, without the need for additional power drive, thus simplifying the structure of the first blocking device 40.

[0085] In some embodiments, the first slide rail 10 may include two parallel rollers, such that the first blocking part 42 and the second blocking part 43 may be disposed in the gap between the two rollers. Of course, the first slide rail 10 may also have other configurations, and this application does not limit them.

[0086] In some embodiments, the conveying mechanism 100 further includes a first mating part 61, which can be fixedly mounted on the fixed frame 60. The lifting frame 7 is also provided with a sliding part 71, which engages with the first mating part 61 to limit the circumferential movement of the lifting frame 7 during its lifting and lowering process. This prevents the lifting frame 7 from swaying during lifting and lowering, improving its stability and thus enhancing the protection of the transported object.

[0087] For example, the sliding part 71 is a pulley, the first mating part 61 is a running track, and the pulley is slidably disposed in the corresponding running track; or, the sliding part 71 is a sleeve, the first mating part 61 is a sliding rod, and the sleeve is fitted into the corresponding sliding rod.

[0088] Understandably, after the crash barrier box 9 is transported to the second slide rail 20, the operator can remove the objects inside for assembly. At this time, the empty crash barrier box 9, without any objects, will be left on the second slide rail 20.

[0089] In some embodiments, the transport mechanism 100 further includes a landing gear 90 disposed on the second side of the slide rail assembly. Here, the second side refers to the side where the second end of the first slide rail 10 and the second end of the second slide rail 20 are located. The structure of the landing gear 90 is similar to that of the lifting frame 7, and will not be described in detail here.

[0090] The drop gear 90 can be raised and lowered between the second end of the second slide rail 20 and the second end of the first slide rail 10. The drop gear 90 is configured to transport the empty crash-proof storage box 9 above the second slide rail 20 back to the first slide rail 10. The empty crash-proof storage box 9 can then be further returned to the lifting frame 7 via the first slide rail 10 so that the operator can continue to place objects.

[0091] In this way, the anti-collision storage box 9 can circulate on the first slide rail 10 and the second slide rail 20. The operator only needs to place the object in the anti-collision storage box 9 or take the object out of the anti-collision storage box 9. There is no need to move the anti-collision storage box 9 anymore, which helps to improve the transportation efficiency of the object and further improve the vehicle assembly efficiency.

[0092] In some embodiments, a second storage tray 91 is rotatably provided on the drop frame 90. A second baffle 911 is provided at the first end of the second storage tray 91 away from the slide rail assembly. A second stop 912 is also provided at the first end of the second storage tray 91, and a second mating part 62 is also provided on the fixing frame 60, the second mating part 62 cooperating with the second stop 912.

[0093] The second storage tray 91 has a third tilt state and a fourth tilt state.

[0094] With the landing gear 90 in the raised state, i.e., at the second end of the second slide rail 20, the second storage tray 91 is in the third tilted state. At this time, the first end of the second storage tray 91 tilts downward under the gravity of the second baffle 911, and the anti-collision storage box 9 can slide onto the second storage tray 91.

[0095] With the lowering gear 90 in the descending state, i.e., at the second end of the first slide rail 10, the second storage tray 91 is in the fourth tilted state. At this time, the second mating part 62 engages with the second stop 912 to tilt the first end of the second storage tray 91 upward, so that the anti-collision storage box 9 can slide out from the second storage tray 91.

[0096] In some embodiments, the angle between the second storage tray 91 and the horizontal plane in the third tilt state is γ1, which can be equal to the tilt angle θ2 of the second slide rail 20. Of course, in some embodiments, γ1 and θ2 may not be equal, for example, |γ1-θ2|≤15°. By limiting the range of the difference between γ1 and θ2, the smoothness of the object sliding between the first slide rail 10 and the second storage tray 91 can be guaranteed.

[0097] The second storage tray 91, in its second tilted state, forms an angle γ2 with the horizontal plane. γ2 can be equal to the tilt angle θ1 of the first slide rail 10. Of course, in some embodiments, γ2 and θ1 may not be equal; for example, |γ2-θ1|≤15°. By limiting the range of the difference between γ2 and θ1, the smoothness of the object sliding between the second storage tray 91 and the second slide rail 20 can be ensured.

[0098] Since the anti-collision storage box 9 is relatively light when not carrying any objects, the raising and lowering of the landing gear 90 can be achieved without a power unit. Figure 3 As shown, the transport mechanism 100 also includes a second counterweight 80 and a second rope 801. The second counterweight 80 is connected to the landing gear 90 via the second rope 801, and the second rope 801 passes through the top of the fixed frame 60 to suspend the second counterweight 80 from the fixed frame 60.

[0099] In some embodiments, the weight of the second counterweight 80 is greater than the total weight of the landing gear 90 and the second storage tray 91, but less than the total weight of the landing gear 90, the second storage tray 91, and the crash barrier storage box 9. This allows the landing gear 90 to move the crash barrier storage box 9 without requiring power.

[0100] When the anti-collision storage box 9 is installed on the second storage tray 91, the total weight of the drop frame 90, the second storage tray 91 and the anti-collision storage box 9 is greater than the weight of the second counterweight 80, and the drop frame 90 descends to the second end of the first slide rail 10 under the action of gravity.

[0101] After the anti-collision storage box 9 on the second storage tray 91 slides to the first slide rail 10, the weight of the second counterweight 80 is greater than the total weight of the drop frame 90 and the second storage tray 91. Driven by the second counterweight 80, the drop frame 90 rises to the second end of the second slide rail 20 to continue receiving the anti-collision storage box 9 on the second slide rail 20.

[0102] In some embodiments, the second rope 801 may be wound around a pulley at the top of the fixed frame 60, thereby reducing the friction of the second rope 801 during movement along the fixed frame 60, thus extending the service life of the second rope 801 and improving the stability of the transport mechanism 100 operation.

[0103] In some embodiments, the transport mechanism 100 further includes a locking device 92, which is fixedly mounted on the mounting frame 60 and located at the second end of the second slide rail 20. The locking device 92 is configured to secure the drop frame 90 in an elevated state, facilitating the operator to retrieve parts from the anti-collision storage box 9 on the second storage tray 91. After the parts in the anti-collision storage box 9 have been used up, the operator can open the locking device 92, causing the drop frame 90 to lower the empty anti-collision storage box 9 onto the first slide rail 10.

[0104] In some embodiments, the conveying mechanism 100 further includes a second blocking device 93, which is disposed at the second end of the second slide rail 20 and configured to allow the anti-collision storage boxes 9 on the second slide rail 20 to be released one by one. The second blocking device 93 includes a second body portion 931, a third blocking portion 932, a fourth blocking portion 933, a second elastic member 934, and a second rotating shaft 935. The structure of the second blocking device 93 is similar to that of the first blocking device 40, and will not be described again here.

[0105] Unlike the first blocking device 40, the second body portion 931 of the second blocking device 93 no longer extends beyond the second end of the second slide rail 20, and the transition between the third and fourth blocking states of the second blocking device 93 is achieved through manual control. For example, the operator can release or block the anti-collision storage box 9 by pressing down on or releasing the second body portion 931.

[0106] Thus, by setting the second blocking device 93, when multiple anti-collision storage boxes 9 are set on the second slide rail 20, the second blocking device 93 can temporarily store the multiple anti-collision storage boxes 9 on the second slide rail 20, thereby making it easier to transport and assemble objects.

[0107] In some embodiments, the second slide rail 20 may include two parallel rollers, such that the third blocking part 932 and the fourth blocking part 933 can be disposed in the gap between the two rollers. Of course, the second slide rail 20 may also have other configurations, which are not limited in this application.

[0108] The working process of the transportation agency 100 is described below as an example.

[0109] In the initial state, the lifting frame 7 is in the lowered position. The lifting frame 7 presses down the first end of the first body part 41 of the first blocking device 40. At this time, the second blocking part 43 lifts up and extends to block the rear anti-collision storage box 9. The first blocking part 42 retracts, and the anti-collision storage box 9 in front of the second blocking part 43 slides out of the first storage tray 8.

[0110] After the work is completed at a low height, the operator can place the objects to be used or assembled (e.g., vehicle parts) on the first storage tray 8. It should be noted that at this time, due to gravity, the first storage tray 8 naturally tilts forward to facilitate the placement of objects. Since this application is typically used for easily scratched exterior parts, a crash-resistant storage box 9 is added for transportation.

[0111] After placing the object stably, the operator can turn on the air intake switch 1 and start the cylinder 2. During the air intake process, the cylinder 2 retracts the linkage rod 3, which in turn pulls the pulley block 4 to retract the traction rope 5. Thus, under the combined action of the cylinder 2 and the first counterweight 70, the lifting frame 13 is lifted, thereby causing the connected first storage tray 8 to rise together.

[0112] After the lifting frame 7 rises, the pressure at the first end of the body part 41 of the double blocking device 40 is released. Under the elastic force of the first elastic member 44, the first blocking device 40 returns to the first blocking state. At this time, the second blocking position 142 descends and retracts, the anti-collision storage box 9 behind the second blocking position 142 moves forward, and the first blocking part 42 rises and extends above the first slide rail 10 to block the aforementioned forward-moving anti-collision storage box 9.

[0113] When the lifting frame 7 rises to its limit position, i.e., the first end of the second slide rail 20, the first end of the second slide rail 20 presses down the first stop 83, causing the object to slide out of the first storage tray 8. During the sliding process, the object will touch the vent switch 6, causing the cylinder 2 to release air. During the air release process, the linkage rod 3 extends, thereby releasing the tension rope 12. At this time, the lifting frame 13 descends, and the first storage tray 8 returns to its forward-tilted position.

[0114] In the initial state, the landing gear 90 is in the raised position, located at the second end of the second slide rail 20, and the locking device 92 is locked. Objects transported by the lifting frame 7 to the second slide rail 20 slide to the second storage tray 91 of the landing gear 90. After the operator removes the desired object from the anti-collision storage box 9 on the landing gear 90, the locking device 92 is released. The landing gear 90 descends to the second end of the first slide rail 10, and the second stop 912 at the end of the second storage tray 91 is lifted upwards by the stop of the second mating part 62, causing the anti-collision storage box 9 on the second storage tray 91 to return to the first slide rail 10 and reach the lifting frame 7 again at the first end of the first slide rail 10 to load objects and proceed with the next transport.

[0115] In summary, the conveying mechanism 100 provided in some embodiments of this application utilizes a clever combination of cylinder 2, connecting rod 3, and pulley block 4 to provide lifting power for the lifting frame 7, thereby lifting and transporting objects placed at a lower position to a higher position for easy delivery to the place of use. The first and second blocking devices enable the release of objects one by one. An air release switch 6 is installed on the second slide rail 20 to achieve automatic return of the lifting frame 7. The drop frame enables the anti-collision storage box 9 to circulate between the second slide rail 20 and the first slide rail 10, saving manpower and improving the efficiency of handling objects such as automotive parts. Furthermore, except for cylinder 2, the operation of the other components does not require additional power drive, saving energy.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
