Description

Technical Field

[0001] This utility model relates to the field of material handling technology for electric vehicle assembly, and specifically discloses a material handling device for electric vehicle assembly. Background Technology

[0002] Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Generally speaking, an electric vehicle uses a battery as its energy source and converts electrical energy into mechanical energy through components such as a controller and a motor to move the vehicle. The speed is changed by controlling the amount of current. During the production process, electric vehicles require the assembly of parts, and the parts need to be transported by material handling equipment during the assembly process.

[0003] Existing material handling devices for electric vehicle assembly generally rely on ordinary flatbed trolleys for manual transport and turnover, which presents the following significant problems:

[0004] 1. The placement plane of a regular flatbed trolley is low and fixed. When unloading, it is impossible to flexibly adjust the placement plane of the material according to the height of the assembly station or the height of the operator. It is necessary to manually bend over repeatedly to pick up and put down the material, which is labor-intensive and inconvenient to operate.

[0005] 2. Ordinary flatbed trolleys lack limiting mechanisms for parts, which can easily slip during transport, posing a risk of injuring people or damaging precision components (such as controllers). Utility Model Content

[0006] This utility model proposes a material handling device for electric vehicle assembly, which can flexibly adjust the height of the material placement plane according to the height of the assembly station or the height of the operator, eliminating the need for manual bending over to pick up and put down materials, effectively reducing the intensity of manual labor, and is easy to use. In addition, it can limit the movement of parts to prevent parts from slipping during the transfer process, which may cause injury to personnel or damage to precision components.

[0007] This utility model is implemented as follows: a material conveying device for electric vehicle assembly includes a base, a placement plate is provided above the base, a lifting mechanism is provided between the base and the placement plate, and a limit mechanism is provided on the upper end surface of the placement plate.

[0008] The lifting mechanism includes two first fixed blocks fixedly connected to the middle part of the lower end face of the placement plate and distributed front and back. A first crossbar is fixedly connected between the two first fixed blocks. Two movable plates distributed left and right are provided on the upper end face of the base. Two second fixed blocks distributed front and back are fixedly connected to the upper end face of each of the two movable plates. A second crossbar is fixedly connected between the two front and back second fixed blocks. Two connecting rods distributed front and back are movably connected between the two second crossbars and the first crossbar. Two vertical plates located on the left and right sides of the two movable plates are fixedly connected to the upper end face of the base. A bidirectional screw threadedly connected to the two movable plates is rotatably connected between the two vertical plates.

[0009] The limiting mechanism includes multiple grooves evenly distributed on the upper surface of the placement plate, each groove having a limiting rod slidably connected inside, and each groove and the limiting rod being fixedly connected with a spring.

[0010] As a preferred embodiment of the material handling device for electric vehicle assembly according to this utility model, a plurality of evenly distributed multi-stage telescopic rods are fixedly connected between the base and the placement plate.

[0011] As a preferred embodiment of the material handling device for electric vehicle assembly according to this utility model, a slide rod located on the front and rear sides of the bidirectional screw and slidably connected to the two moving plates is fixedly connected between the two vertical plates.

[0012] As a preferred embodiment of the material handling device for electric vehicle assembly according to this utility model, a stepper motor is installed on the left side wall of the vertical plate on the left side, and the output end of the stepper motor is fixedly connected to a bidirectional screw.

[0013] As a preferred embodiment of the material handling device for electric vehicle assembly according to this utility model, the lower end face of the base is equipped with a plurality of evenly distributed omnidirectional wheels with brakes, and the upper end face of the base is fixedly connected to a push rod on the right side.

[0014] In a preferred embodiment of the material handling device for electric vehicle assembly according to this utility model, the groove and the limiting rod are slidably connected by a limiting groove and a limiting slider.

[0015] As a preferred embodiment of the material conveying device for electric vehicle assembly according to this utility model, the upper end of the limiting rod is configured as a spherical structure.

[0016] The beneficial effects of this utility model are:

[0017] The two moving plates are driven to move in opposite directions by a double screw. The two moving plates, together with two second crossbars, multiple connecting rods and the first crossbar, drive the placement plate to rise, thereby adjusting the height of the placement plate. This allows the height of the placement plate to be flexibly adjusted according to the height of the assembly station or the height of the operator, eliminating the need for manual bending over to pick up and put down materials, effectively reducing the intensity of manual labor, and making it easy to use.

[0018] The component is placed on the upper surface of the placement plate, and the component's weight is used to press down on the multiple limiting rods covered by the component, causing the multiple limiting rods covered by the component to enter the multiple corresponding grooves. At the same time, other multiple limiting rods are located around the component to limit the component and prevent the component from slipping during transportation, which could cause injury to personnel or damage to precision parts.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0025] Please see Figure 1-3A material handling device for electric vehicle assembly includes a base 1, a placement plate 2 is provided above the base 1, a lifting mechanism is provided between the base 1 and the placement plate 2, and a limit mechanism is provided on the upper end surface of the placement plate 2.

[0026] The lifting mechanism includes two first fixed blocks 3 fixedly connected to the middle part of the lower end face of the placement plate 2 and distributed front and back. A first crossbar 4 is fixedly connected between the two first fixed blocks 3. Two movable plates 5 distributed left and right are provided on the upper end face of the base 1. Two second fixed blocks 6 distributed front and back are fixedly connected to the upper end face of each of the two movable plates 5. A second crossbar 7 is fixedly connected between the two second fixed blocks 6. Two connecting rods 8 distributed front and back are movably connected between the two second crossbars 7 and the first crossbar 4. Two vertical plates 9 located on the left and right sides of the two movable plates 5 are fixedly connected to the upper end face of the base 1. A bidirectional screw 10 threadedly connected to the two movable plates 5 is rotatably connected between the two vertical plates 9.

[0027] The limiting mechanism includes multiple grooves 11 that are evenly distributed on the upper surface of the placement plate 2. Each groove 11 is slidably connected to a limiting rod 12, and each groove 11 and the limiting rod 12 is fixedly connected to a spring 13.

[0028] In this embodiment: when adjusting the height of the placement plate 2, the bidirectional screw 10 rotates, and the bidirectional screw 10 drives the two moving plates 5 to move in opposite directions. The two moving plates 5, together with the two second crossbars 7, multiple connecting rods 8 and the first crossbar 4, drive the placement plate 2 to rise, thereby adjusting the height of the placement plate 2. This allows the height of the placement plate 2 to be flexibly adjusted according to the height of the assembly station or the height of the operator, eliminating the need for manual bending over to pick up and put down materials, effectively reducing the intensity of manual labor, and making it convenient to use. During the rising process of the placement plate 2, multiple multi-stage telescopic rods 14 can limit the placement plate 2, allowing the placement plate 2 to move smoothly.

[0029] When placing components on the placement plate 2, the components first come into contact with multiple limiting rods 12. Then, the weight of the components presses down on the multiple limiting rods 12 covered by the components, causing the multiple limiting rods 12 covered by the components to enter the corresponding multiple grooves 11 and compress and contract the corresponding springs 13. At the same time, other multiple limiting rods 12 are located around the components to limit the components and prevent the components from slipping during transportation, which could cause injury to personnel or damage to precision parts. In addition, the multiple limiting rods 12 can also limit components of different specifications.

[0030] As a technical optimization of this utility model, a plurality of evenly distributed multi-level telescopic rods 14 are fixedly connected between the base 1 and the placement plate 2.

[0031] In this embodiment, the placement plate 2 can be limited by multiple multi-stage telescopic rods 14, so that the placement plate 2 can move smoothly.

[0032] As a technical optimization of this utility model, a slide rod 15 is fixedly connected between the two vertical plates 9, located on the front and rear sides of the bidirectional screw 10, and slidably connected to the two movable plates 5.

[0033] In this embodiment, two sliding rods 15 can limit the movement of the two moving plates 5, allowing the two moving plates 5 to move smoothly.

[0034] As a technical optimization of this utility model, a stepper motor 16 is installed on the left side wall of the left vertical plate 9, and the output end of the stepper motor 16 is fixedly connected to the bidirectional screw 10.

[0035] In this embodiment, the stepper motor 16 can drive the bidirectional screw 10 to rotate.

[0036] As a technical optimization of this utility model, a plurality of evenly distributed casters 17 with brakes are installed on the lower end face of the base 1, and a push rod 18 is fixedly connected to the right end of the upper end face of the base 1.

[0037] In this embodiment, the device is easily moved by multiple casters 17 and push rods 18.

[0038] As a technical optimization of this utility model, the groove 11 and the limiting rod 12 are slidably connected by a limiting groove and a limiting slider.

[0039] In this embodiment, the limiting rod 12 can be limited by the limiting groove and the limiting slider, which can make the limiting rod 12 move smoothly while preventing the limiting rod 12 from falling out of the groove 11.

[0040] As a technical optimization of this utility model, the upper end of the limiting rod 12 is set as a spherical structure.

[0041] In this embodiment, the upper end of the limiting rod 12 is set as a spherical structure, which can prevent the upper end of the limiting rod 12 from scratching the outer wall of the component.

[0042] The working principle and usage process of this utility model are as follows: When adjusting the height of the placement plate 2, the stepper motor 16 drives the bidirectional screw 10 to rotate, and the bidirectional screw 10 drives the two moving plates 5 to move in opposite directions. The two moving plates 5, together with the two second crossbars 7, multiple connecting rods 8 and the first crossbar 4, drive the placement plate 2 to rise, thereby adjusting the height of the placement plate 2. Thus, the height of the placement plate 2 can be flexibly adjusted according to the height of the assembly station or the height of the operator.

[0043] When placing the component on the placement plate 2, the component first contacts multiple limiting rods 12, and then the component's weight presses down on the multiple limiting rods 12 covered by the component, causing the multiple limiting rods 12 covered by the component to enter the corresponding multiple grooves 11. At the same time, other multiple limiting rods 12 are located around the component to limit the component and prevent the component from slipping during transportation, which could cause injury to personnel or damage to precision parts.

[0044] In the description of this utility model, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inner", "outer", "back", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0045] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
