Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and in particular to a logistics conveyor for the safe transport of lithium batteries. Background Technology

[0002] During the transportation of lithium batteries for new energy vehicles, it is necessary to maintain the safety of the lithium batteries. Currently, lithium batteries are generally transported using equipment such as forklifts, which can easily cause damage from impacts. Using a roller conveyor to transport lithium batteries is much better. However, there are still issues such as the possibility of damage caused by direct contact between the lithium battery casing and the roller conveyor. In the prior art, patent CN110282379A discloses an automatic loading and unloading roller conveyor for lithium battery trays, which includes a double-layer roller conveyor body. In use, the conveyor is transported along the upper conveyor line to the loading and unloading device, which then transfers the conveyor to the lower conveyor. The whole machine replaces manual labor to realize the automatic loading and unloading of lithium batteries. In this kind of equipment, a tray needs to be placed under the lithium battery before it is placed on the roller conveyor, which is difficult to operate and the tray is inconvenient to retrieve. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the prior art, the present invention provides a logistics conveyor for the safe transport of lithium batteries, which can provide protection for lithium batteries during the transport process.

[0004] Technical solution: To achieve the above objectives, the present invention provides a logistics conveyor for the safe transport of lithium batteries, which includes a main conveyor line and a pallet conveyor line for transporting pallets.

[0005] The main conveyor line and the tray conveyor line are arranged vertically and vertically, and their conveying directions are opposite.

[0006] The main conveyor line is equipped with a tray lifting mechanism at both ends.

[0007] The pallet has a through-hole section; the pallet lifting mechanism includes a main lifting body and a secondary lifting body; both the main lifting body and the secondary lifting body have roller sections; the main lifting body can be lifted and lowered relative to the main conveyor line, and the secondary lifting body can be lifted and lowered relative to the main lifting body.

[0008] Specifically, the pallet lifting mechanism located at the beginning of the main conveyor line operates as follows: Initially, the upper ends of the main lifting body, the auxiliary lifting body, and the pallet conveyor line are aligned. The pallet conveyor line transports the pallet to the upper end of the main lifting body, with the auxiliary lifting body aligned vertically with the empty slot. Then, the auxiliary lifting body rises relative to the main lifting body, passing through the empty slot, and its height is higher than that of the main lifting body. Simultaneously, the main lifting body is controlled to rise relative to the main conveyor line, so that the upper end of the auxiliary lifting body is aligned with the upper end of the main conveyor line. At this point, the auxiliary lifting body can receive externally placed lithium batteries, with its lower side aligned with the upper end of the main conveyor line when the lithium batteries are input. After the lithium batteries are in place, the auxiliary lifting body descends, allowing the lithium batteries to be supported by the main lifting body, and the main lifting body rises to a position where its upper end is aligned with the upper end of the main conveyor line. The rollers on the main lifting body rotate to place the lithium batteries, along with the pallets, onto the main conveyor line. Finally, the pallet lifting mechanism resets to its initial state.

[0009] The operation of the pallet lifting mechanism located at the end of the main conveyor line is as follows: In the initial state, the main lifting body is positioned with its upper end flush with the upper end of the main conveyor line; the auxiliary lifting body is not higher than the main lifting body; when a lithium battery with a pallet is delivered to the top of the main lifting body, firstly, the auxiliary lifting body rises to push the lithium battery off the pallet, then the main lifting body descends so that the upper end of the auxiliary lifting body is flush with the upper end of the main conveyor line, and the auxiliary lifting body outputs the lithium battery. Subsequently, the auxiliary lifting body descends to a position lower than the main lifting body, and the main lifting body descends to a position where its upper end is flush with the upper end of the pallet conveyor line, and the main lifting body operates to place the pallet onto the pallet conveyor line.

[0010] By operating in the above manner, the pallets can be recycled and reused, ensuring the safety of lithium batteries during the conveying process, isolating lithium batteries from direct contact with the main conveyor line, and preventing lithium batteries from colliding with the edges of the main conveyor line.

[0011] Furthermore, the pallet lifting mechanism is also connected to the pallet supply mechanism.

[0012] Furthermore, the pallet supply organization includes a pallet warehouse, in which pallets are stacked, and a pallet separation mechanism is installed within the pallet warehouse.

[0013] Furthermore, the pallet lifting mechanism also includes a mechanism base, on which four symmetrically installed slides are mounted, divided into two groups. Two slides in the same group are respectively equipped with a left-hand nut and a right-hand nut, and the left-hand and right-hand nuts corresponding to the two slides in the same group cooperate with the same bidirectional lead screw, which has a left-hand threaded portion and a right-hand threaded portion. The four slides are respectively connected to the four corners of the main lifting body via connecting rods. The two bidirectional lead screws corresponding to the two groups of slides are driven by the same lifting motor through a synchronous belt mechanism. Utilizing the self-locking feature of the lead screw, the main lifting body can be effectively kept in place in case of accidental power failure.

[0014] Furthermore, the main lifting body includes a main frame and a first roller mounted on the main frame; the main frame is also equipped with a drive assembly for driving the auxiliary lifting body to rise and fall.

[0015] Furthermore, the auxiliary lifting body includes a secondary frame, which has two symmetrically mounted upper protrusions, and each upper protrusion has multiple second rollers mounted on its upper end.

[0016] Furthermore, multiple guide rods are symmetrically installed at the lower end of the sub-frame, and multiple guide sleeves are installed at the upper end of the main frame. The guide sleeves and guide rods are slidably fitted in correspondence. A hydraulic cylinder that acts on the sub-frame is also installed on the main frame.

[0017] Beneficial Effects: The logistics conveyor for the safe transport of lithium batteries of the present invention has the following beneficial effects:

[0018] (1) During operation, the pallet lifting mechanism at the beginning of the main conveyor line is used to provide a pallet to support the lithium battery; the pallet lifting mechanism at the end of the main conveyor line is used to retrieve the pallet at the bottom of the lithium battery. In this way, the lithium battery is protected by the pallet as it moves along the main conveyor line. The pallet can effectively prevent the lithium battery from contacting or bumping with other objects, thus effectively protecting the safety of the lithium battery.

[0019] (2) By setting up a pallet supply mechanism, more usage patterns can be met.

[0020] (3) The lifting of the auxiliary lifting body relative to the main lifting body can reduce the required lifting stroke length of the auxiliary lifting body. The design of each stage of the lifting mechanism is reasonable. The drive component of the auxiliary lifting body is based on hydraulic cylinders, which not only have a large force but also have a buffering and vibration absorption function. The drive structure of the main lifting body is based on the combined action of a two-way lead screw and connecting rod, which can withstand heavy loads, has high lifting reliability, and can self-lock to ensure safety in the event of power failure.

Detailed Implementation

[0027] The invention will now be further described with reference to the accompanying drawings.

[0028] like Figure 1 The logistics conveyor shown is for the safe transport of lithium batteries and includes a main conveyor line 1 and a pallet conveyor line 2 for transporting pallets 4.

[0029] like Figure 2 As shown, the main conveyor line 1 and the tray conveyor line 2 are arranged vertically, and their conveying directions are opposite.

[0030] The main conveyor line 1 is equipped with a tray lifting mechanism 3 at both ends.

[0031] like Figure 3 As shown, the tray 4 has a through slot 41; the tray lifting mechanism 3 includes a main lifting body 31 and a secondary lifting body 32; both the main lifting body 31 and the secondary lifting body 32 have rollers; the main lifting body 31 can be lifted and lowered relative to the main conveyor line 1, and the secondary lifting body 32 can be lifted and lowered relative to the main lifting body 31.

[0032] During operation, the pallet lifting mechanism 3 at the beginning of the main conveyor line 1 provides pallets 4 to support the lithium batteries; the pallet lifting mechanism 3 at the end of the main conveyor line 1 is used to retrieve the pallets 4 from the bottom of the lithium batteries. Thus, the lithium batteries are protected by the pallets 4 as they move along the main conveyor line 1, effectively preventing contact and impacts with other objects and protecting the safety of the lithium batteries.

[0033] Specifically, the pallet lifting mechanism 3 located at the beginning of the main conveyor line 1 operates as follows: Initially, the upper ends of the main lifting body 31, the auxiliary lifting body 32, and the pallet conveyor line 2 are aligned. The pallet conveyor line 2 transports the pallet 4 to the upper end of the main lifting body 31, with the auxiliary lifting body 32 vertically aligned with the empty slot 41. Then, the auxiliary lifting body 32 rises relative to the main lifting body 31, passing through the empty slot 41, and its height is higher than that of the main lifting body 31. Simultaneously, the main lifting body 31 is controlled to rise relative to the main conveyor line 1, so that the upper end of the auxiliary lifting body 32 is aligned with the upper end of the main conveyor line 1. At this time, the auxiliary lifting body 32 can receive externally placed lithium batteries. After the lithium battery is in place, the auxiliary lifting body 32 descends, allowing the lithium battery to be supported by the main lifting body 31. The main lifting body 31 then rises until its upper end is flush with the upper end of the main conveyor line 1. The rollers on the main lifting body 31 rotate to drop the lithium battery, along with the tray 4, onto the main conveyor line 1. Finally, the tray lifting mechanism 3 resets to its initial state.

[0034] The operation of the pallet lifting mechanism 3 located at the end of the main conveyor line 1 is as follows: In the initial state, the main lifting body 31 is positioned with its upper end flush with the upper end of the main conveyor line 1; the auxiliary lifting body 32 is not higher than the main lifting body 31; when a lithium battery with a pallet 4 is transported to the top of the main lifting body 31, firstly, the auxiliary lifting body 32 rises to push the lithium battery away from the pallet 4, and then the main lifting body 31 descends so that the upper end of the auxiliary lifting body 32 is flush with the upper end of the main conveyor line 1, and the auxiliary lifting body 32 outputs the lithium battery. Subsequently, the auxiliary lifting body 32 descends to a position lower than the main lifting body 31, and the main lifting body 31 descends to a position with its upper end flush with the upper end of the pallet conveyor line 2, and the main lifting body 31 operates to place the pallet 4 onto the pallet conveyor line 2.

[0035] By operating in the above manner, the tray 4 can be recycled and reused, ensuring the safety of the lithium battery during the conveying process, isolating the lithium battery from direct contact with the main conveyor line 1, and preventing the lithium battery from colliding with the edge of the main conveyor line 1.

[0036] Preferably, the pallet lifting mechanism 3 is also connected to the pallet supply mechanism 5. The pallet supply mechanism 5 includes a pallet warehouse 51, in which the pallets 4 are stacked, and a pallet separation mechanism is installed. By setting up the pallet supply mechanism 5, in addition to providing pallets 4 to the lithium batteries before they enter the main conveyor line 1 and recycling the pallets 4 after they leave the main conveyor line 1, the following mode can also be used: providing pallets 4 to the lithium batteries before they enter the main conveyor line 1, and having the lithium batteries and pallets 4 taken away together by a forklift. In this mode, the pallet warehouse 51 continuously provides pallets to the pallet lifting mechanism 3, thus enabling more usage modes and meeting different usage needs.

[0037] like Figure 4-5 As shown, the pallet lifting mechanism 3 also includes a mechanism base 33, on which four symmetrically installed slides 34 are mounted, divided into two groups. Two slides 34 in the same group are respectively equipped with a left-hand nut and a right-hand nut, and the left-hand and right-hand nuts corresponding to the two slides 34 in the same group cooperate with the same bidirectional lead screw 35, which has a left-hand threaded portion and a right-hand threaded portion. The four slides 34 are respectively connected to the four corners of the main lifting body 31 via connecting rods 36. The two bidirectional lead screws 35 corresponding to the two groups of slides 34 are driven by the same lifting motor 37 through a synchronous belt mechanism 38. Utilizing the self-locking feature of the lead screw, the main lifting body 31 can be effectively kept in place in case of accidental power failure.

[0038] Preferably, the main lifting body 31 includes a main frame 31a and a first roller 31b mounted on the main frame 31a; the main frame 31a is also equipped with a drive assembly for driving the auxiliary lifting body 32 to rise and fall.

[0039] Preferably, the auxiliary lifting body 32 includes a secondary frame 32a, which has two symmetrically mounted upper protrusions 32b, and each upper protrusion 32b has a plurality of second rollers 32c mounted on its upper end.

[0040] Preferably, a plurality of guide rods 39 are symmetrically installed at the lower end of the sub-frame 32a, and a plurality of guide sleeves 310 are installed at the upper end of the main frame 31a. The guide sleeves 310 and the guide rods 39 are slidably fitted in a one-to-one correspondence. A hydraulic cylinder 311 acting on the sub-frame 32a is also installed on the main frame 31a.

[0041] In the above structure, the lifting of the auxiliary lifting body 32 relative to the main lifting body 31 reduces the required lifting stroke length of the auxiliary lifting body 32. The design of each stage of the lifting mechanism is reasonable. The drive component for the auxiliary lifting body 32 is based on the hydraulic cylinder 311, which not only has a large force but also a buffering and vibration-absorbing function. The drive structure for the main lifting body 31 is based on the combined action of the bidirectional lead screw 35 and the connecting rod 36, which can withstand heavy loads, has high lifting reliability, and is self-locking to ensure safety in the event of power failure.

[0042] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
