Description

Technical Field

[0001] The present application relates to the field of battery production technology, and in particular to an OHT trolley with a side clamping function. Background Art

[0002] Battery finished product pallets are pallets specially used for storing, transporting and storing finished battery products. In the production line, battery pallets need to be transported to the designated location across the production line or workshop according to the station assigned by the system. The existing conveying form is usually a conveyor line installed on the ground, using chain transmission or electric roller transmission, which not only occupies a large ground space, but also easily causes pallet jams or material congestion, reducing production efficiency.

[0003] In order to improve space utilization and increase the transfer efficiency of pallets, pallets can be transferred by air transportation. However, due to the heavy weight of pallets and the fact that pallets usually need to be stacked in multiple layers before being transferred together, the weight of plastic pallets is usually between 10-25 kilograms and the weight of metal pallets is between 20-50 kilograms. Existing air transportation devices (such as suspended mobile vehicles with finger cylinders, vacuum suction cups, etc.) are not suitable for directly transferring pallets. Therefore, an air transportation device suitable for grabbing multiple pallets at the same time is needed. Summary of the invention

[0006] By adopting the above technical solution, after the pallets are stacked, the driving component drives the vehicle body to move on the aerial track so that the vehicle body moves to directly above the pallet, and then the lifting component controls the lifting seat to descend until the stacked multiple pallets are located in the grabbing groove, and then the clamping component controls the two claws to move towards each other, and the two claws clamp multiple pallets. At the same time, the horizontal support plate supports the bottom of the pallet, and the lifting component controls the lifting seat to reset, and then the driving component drives the vehicle body to move to the specified position and unloads the pallet, completing the transfer of the pallet.

[0007] The design of the grab groove opening direction and the clamp arrangement direction prevents the pallet from falling off due to the inertia of the pallet when the vehicle body moves at high speed to stop. The design of the support plate can prevent the pallet from falling due to insufficient friction provided by the clamping, thereby ensuring the stability of the pallet during transportation and reducing the possibility of the pallet tilting or falling.

[0008] Optionally, the vehicle body includes a mounting plate, side panels are installed at both ends of the mounting plate, the two side panels are concave groove plates, the two side panels are installed with electrical base plates, the electrical base plate and the side panels together enclose an installation space for installing a PLC module and a communication module, the mounting plate and the two side panels together form a concave shell, the drive assembly is installed on the top of the mounting plate, and the lifting assembly and the lifting seat are both located between the two electrical base plates.

[0009] By adopting the above technical solution, the car body is designed as a concave shell, which can reduce the weight of the car body. The combination of the concave groove plate side plate and the electrical bottom plate provides a special space for installing the PLC module and the communication module. This design integrates the electrical components inside the car body, avoids exposed wiring and equipment, reduces space occupation, and optimizes the internal layout of the car body.

[0015] By adopting the above technical solution, the second motor drives the second reducer to operate, so that the winches on both sides of the second reducer rotate at the same time, and the winch wheels control the traction belt to reel in and unreel, thereby realizing the lifting and lowering of the lifting seat. Multiple traction belts simultaneously lift or lower the lifting seat, so that the lifting seat can be lifted and lowered smoothly, avoiding the situation where shaking causes deviation, so that the lifting seat can be aligned with the pallet, which is convenient for the clamp to grasp stably.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-6 This application is described in further detail.

[0035] The embodiment of the present application discloses an OHT trolley with a side clamping function.

[0036] like Figure 1The OHT trolley with side clamping function includes a car body 1, which includes a mounting plate 11.

[0037] like Figure 1 , Figure 2 and Figure 3 A driving assembly 2 is installed on the top surface of the mounting plate 11. The driving assembly 2 includes two rotating seats 21. The rotating seat 21 includes a fixed sleeve 211. A rotating shaft 212 is arranged in the fixed sleeve 211. One end of the rotating shaft 212 is rotatably connected to the mounting plate 11, and the other end of the rotating shaft 212 is connected to the mounting seat 22. A bearing 213 is arranged on the rotating shaft 212. The bearing 213 is located in the fixed sleeve 211 and is adapted to it. The mounting seat 22 is a rectangular shell with an opening on one side. A first reducer 23 is fixed inside the mounting seat 22. Both ends of the mounting seat 22 are rotatably connected to active walking wheels 24. The two active walking wheels 24 are connected to the first reducer 23. The first reducer 23 is connected to a first motor 25. The top of the mounting seat 22 is rotatably connected to four auxiliary walking wheels 26. The bottom of the mounting seat 22 is rotatably connected to two auxiliary walking wheels 26. The central axis of the auxiliary walking wheel 26 is arranged in the vertical direction. A barcode scanning locator 27 and a power brush 28 are installed at the top center of the mounting plate 11.

[0038] like Figure 4 A lifting assembly 3 is installed at the bottom of the mounting plate 11. The lifting assembly 3 includes a second reducer 31. Both sides of the second reducer 31 are connected to winch wheels 32. The two winch wheels 32 are arranged along the width direction of the aerial track. The second reducer 31 is connected to a second motor 33. Both sides of the bottom of the mounting plate 11 are rotatably connected to two lifting auxiliary wheels 34. The winch wheel 32 is located between the two lifting auxiliary wheels 34 on the same side. Each lifting auxiliary wheel 34 is wrapped with a traction belt 35. One end of each traction belt 35 is wrapped and fixed on the winch wheel 32 on the same side. The two traction belts 35 on the same side are wound in opposite directions. The four traction belts 35 are commonly connected to the lifting seat 4.

[0039] The outer shell of the lifting seat 4 is concave, and the concave part of the lifting seat 4 is a grabbing groove 41. The size of the grabbing groove 41 is larger than the size of the tray. The grabbing groove 41 is longer than 520mm, wider than 500mm, and higher than 270mm. The grabbing groove 41 is set through along the width direction of the aerial track.

[0040] like Figure 5 , an assembly plate 42 is installed in the lifting seat 4, and a space is left between the assembly plate 42 and the top of the shell of the lifting seat 4. Four traction belts 35 pass through the top of the shell of the lifting seat 4 and are respectively fixed on the four corners of the assembly plate 42. An installation groove 421 is opened in the middle of the assembly plate 42, and two clamping claws 43 are slidably connected to the bottom of the assembly plate 42. The two clamping claws 43 are respectively located at one end of the assembly plate 42. A transverse support plate 431 is installed at the bottom of the opposite side of the two clamping claws 43. The tops of the two clamping claws 43 are connected to the assembly plate 42 through a slide rail. A clamping assembly 5 for controlling the relative movement of the two clamping claws 43 is provided on the assembly plate 42; like Figure 5 and Figure 6 The clamping assembly 5 includes a servo electric cylinder 51, which is installed in one end of the installation groove 421. A base plate 52 is installed at the end of the assembly plate 42 away from the servo electric cylinder 51. The base plate 52 is slidably connected with two tie rods 53. The two tie rods 53 are extended along the length direction of the vehicle body 1. Driving teeth 531 are provided on the opposite sides of the two tie rods 53. A gear 54 is rotatably connected to the base plate 52, and the gear 54 is engaged with the driving teeth 531 of the two tie rods 53 at the same time. One end of one of the tie rods 53 is connected to the servo electric cylinder 51, and the other end is connected to one clamping claw 43. One end of the other tie rod 53 is connected to the other clamping claw 43.

[0041] like Figure 4 and Figure 5 A proximity switch 44 is installed on the assembly plate 42, one end of the proximity switch 44 passes through the top surface of the lifting seat 4, a limit plate 36 is installed at the bottom of the second reducer 31, and the proximity switch 44 is directly opposite to the limit plate 36. Conical guide columns 45 are installed on both sides of the lifting seat 4, and a guide sleeve 37 is installed on the bottom surface of the mounting plate 11. The guide sleeve 37 corresponds to the conical guide column 45 one by one, and a photoelectric sensor 38 is arranged on the guide sleeve 37.

[0042] The charger transmitting end 61 is installed at the bottom of the mounting plate 11, and the charger receiving end 62 and the battery module 63 are installed on the base plate 52. The charger receiving end 62 is directly opposite to the charger transmitting end 61. The charging module supplies power to the servo cylinder 51, and the power-taking brush 28 supplies power to the first motor 25, the second motor 33, the charger transmitting end 61, and the PLC module, the communication module and other components. The first laser rangefinder 71 is installed at the bottom of the two side plates 12, and the second laser rangefinder 72 is installed at the bottom of the mounting plate 11, and the second laser rangefinder 72 is directly opposite to the top of the lifting seat 4.

[0043] When transferring the stacked three-layer pallet, the first motor 25 drives the first reducer 23 to move, and the first reducer 23 controls the active walking wheel 24 to move. When passing the turning point of the aerial track, since the mounting seat 22 is rotatably connected with the vehicle body 1 through the rotating shaft 212, the mounting seat 22 can realize automatic steering at the turning point of the aerial track, so that the vehicle body 1 can turn smoothly, and the cooperation of multiple auxiliary walking wheels 26 ensures that the vehicle body 1 will not deviate or derail when walking on the track. When the vehicle body 1 is moving, it cooperates with the barcode scanning locator 27 for precise positioning, so that the vehicle body 1 can accurately reach the position directly above the pallet, and at this time, the grabbing slot 41 is aligned with the pallet; Then, the second motor 33 is started to drive the second reducer 31 to operate, so that the winches 32 on both sides of the second reducer 31 rotate simultaneously, and the winches 32 control the traction belt 35 to reel in and unreel, thereby realizing the lifting and lowering of the lifting seat 4. Multiple traction belts 35 simultaneously pull or lower the lifting seat 4, so that the lifting seat 4 can be lifted and lowered smoothly to avoid the situation where the shaking causes the displacement, so that the lifting seat 4 can be aligned with the pallet. Before descending, the first laser rangefinder 71 detects the vertical distance between the vehicle body 1 and the bottom of the pallet, and then the lifting seat 4 is lowered. The second laser rangefinder 72 detects the descending distance of the lifting seat 4, so that the lifting and lowering position of the lifting seat 4 is accurate; After the lifting seat 4 is lowered until all three layers of pallets are located in the grabbing groove 41, the servo electric cylinder 51 controls a pull rod 53 to move, and the driving tooth 531 of the pull rod 53 drives the gear 54 to rotate when moving, so that the other pull rod 53 moves, and the two pull rods 53 move the same distance, so that the two clamping claws 43 can move relative to each other synchronously to clamp the pallet, and the horizontal support plate 431 is inserted into the bottom of the pallet; Then the second motor 33 starts to control the lifting seat 4 to reset. During the resetting process of the lifting seat 4, the driving assembly 2 then drives the vehicle body 1 to move to the designated position and unloads the pallet. When the pallet is transported, the conical guide column 45 is designed to be conical, so it can be accurately aligned with the guide sleeve 37. When the lifting seat 4 is in the process of rising, the conical guide column 45 gradually inserts into the guide sleeve 37, and its conical structure automatically guides and corrects the position of the lifting seat 4. This design can compensate for the slight position deviation caused by uneven load or equipment vibration, thereby ensuring that the lifting seat 4 can accurately reset to the same position every time. When the lifting seat 4 reaches the reset position, the conical guide column 45 covers the photoelectric sensor 38 and controls the second motor 33 to stop, so that the lifting seat 4 accurately stays at the reset position, thereby improving the reset accuracy.

[0044] Then the first motor 25 starts again to drive the vehicle body 1 to move to the pallet below the designated position, completing the transfer of the multi-layer pallet. When the vehicle body 1 is moving, the power brush 28 contacts the busbar on the aerial track, and the power is supplied to the busbar. The power brush 28 supplies power to the entire drive assembly 2, the lifting assembly 3 and the charger transmitter 61. When the lifting seat 4 is reset in the vehicle body 1, the charger receiver 62 is docked with the charger transmitter 61, and the proximity switch 44 is close to the limit plate 36. At this time, the charger transmitter 61 is started and supplies power to the charger receiver 62, thereby charging the battery module 63. When the lifting seat 4 descends, the battery module 63 supplies power to the clamping assembly 5 to grasp the material.

[0045] The vehicle body 1 is transported via an aerial track, which reduces the ground space occupied compared to traditional ground chain transmission or electric roller transmission. This not only frees up ground space, which is suitable for production lines or workshops with limited space, but also reduces the risk of production interruption caused by ground equipment failure; The design of the opening direction of the grabbing groove 41 and the arrangement direction of the clamping claws 43 prevents the pallet from falling off due to the inertia of the pallet when the vehicle body 1 moves at high speed to stop moving, and the design of the transverse support plate 431 can prevent the pallet from falling due to insufficient friction provided by the clamping, thereby ensuring the stability of the pallet during transportation and reducing the possibility of the pallet tilting or falling; The built-in battery module 63 provides an independent power source, which, combined with the power brush 28 and charger system installed on the vehicle body 1, ensures that the device can be continuously powered during long-term operation, while simplifying power management and enhancing the mobility and flexibility of the system; In summary, the first motor 25 drives the active walking wheel 24, the barcode scanning locator 27 performs precise positioning, the OHT trolley has fast acceleration, high load, high positioning accuracy, high transmission efficiency, long service life, good working stability and high reliability; compared with the transmission conveyor line mechanism that occupies a large amount of ground space, the OHT trolley can improve the utilization rate of the workshop space, reduce manpower and improve production efficiency.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
