Technical Field

[0001] The invention relates to the technical field of material conveying equipment in a workshop, in particular to an aluminum shell loading trolley. Background Art

[0002] Aluminum shell, made of aluminum alloy, is used to place and wrap lithium battery core or stacked core. It mainly protects internal components. The shell body is made of high-quality aluminum alloy profiles. It has the characteristics of reasonable design, solid structure and beautiful appearance. It is widely used in the lithium battery production industry.

[0003] In the production process of lithium batteries, an aluminum shell loading trolley is required to load the aluminum shells and then grab them by a robot. With the promotion of lithium batteries, there are more and more battery models, but the existing aluminum shell loading trolleys are mostly integrated designs. Different types of lithium batteries need to be redesigned and manufactured, resulting in waste in design and production.

[0004] In addition, the existing aluminum shell loading trolley is mostly loaded manually by operators, which reduces the overall practicality, wastes unnecessary time and manpower, is inconvenient for people to use, and thus reduces the battery production efficiency. Summary of the invention

[0005] The purpose of the present invention is to provide an aluminum shell loading trolley to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] An aluminum shell loading trolley comprises a vehicle body, the vehicle body comprises a vehicle frame, a material frame is movably connected to the vehicle frame, the material frame comprises a material frame bottom plate movably connected to the vehicle frame and at least one jig for carrying materials detachably connected to the material frame bottom plate.

[0008] By providing a detachably connected fixture, fixtures of different specifications can be replaced as needed, thereby adapting to different production needs.

[0009] As a further solution of the present invention: two parallel outer support bars are provided on the frame, a first short friction bar is provided on the inner side of the outer support bar, a roller assembly is provided between the outer support bars on both sides, the material frame bottom plate is slidably connected to the roller assembly, and the material frame bottom plate is located between the first short friction strips on both sides.

[0010] By arranging the roller assembly and the first short friction strip, the material frame bottom plate can slide horizontally on the frame, thereby reducing the labor intensity of loading and unloading materials, and also reducing the friction of loading and unloading materials, thereby increasing the service life of the material frame bottom plate and the frame.

[0011] As a further solution of the present invention: a power unit for driving the material frame bottom plate to slide on the roller assembly is provided on the frame, and the power unit includes a lead screw arranged on the frame, and inner support strips are provided on both sides of the lead screw, and connecting blocks are clamped on both sides of the material frame bottom plate, and the connecting block is fixedly connected to the material frame bottom plate through a connecting pin, and a movable block is connected to the lower end of the connecting block, and the movable block is threadedly connected to the lead screw, and the movable block is slidably connected in a long strip groove formed by two inner support strips, and one end of the lead screw is connected to an external motor through a bearing.

[0012] By setting a lead screw and an external motor, the material frame can be driven to move on the frame by an external power, thereby reducing the labor intensity of workers.

[0014] By setting the roller, the friction resistance can be reduced and the smoothness of loading and unloading of materials can be improved. By setting the detachable friction strip, the friction strip can be replaced after wear to increase the service life of the material frame bottom plate.

[0015] As a further solution of the present invention: the outer support bar is fixedly connected to the upper end of the frame through a welding plate, and both ends of the outer support bar are provided with bevels, and the bevels are located on the inner side of the outer support bar. Positioning blocks are provided on both sides of the material frame bottom plate, and the outer support bar is provided with positioning holes that cooperate with the positioning blocks. A block seat is provided in the positioning hole, and the block seat is provided with a block and a block pin for fixedly connecting the block seat and the positioning block.

[0016] The inclined opening makes it easier for the material frame to enter the vehicle frame. The material frame can be fixedly connected to the vehicle frame by means of a clamping block and a clamping block pin, thereby preventing the material frame from moving relative to the vehicle frame during movement.

[0018] The direction of the friction plate is perpendicular to the direction of the roller and the lower bottom surface is lower than the bottom plate and the bottom strip. When the material frame slides on the roller, the friction plate is in direct contact with the roller and rolls on the roller to avoid friction between the roller and the bottom plate or the bottom strip causing wear on both. When the friction plate is damaged, it can be directly replaced, which is convenient for disassembly and replacement.

[0019] As a further solution of the present invention: a plurality of jig spaces for accommodating the jig are arranged on the material frame bottom plate, each of the jig spaces is provided with a plurality of positioning pins fixedly connected to the material frame bottom plate, a guide sleeve cooperating with the positioning pin is provided at the lower end of the jig, and the positioning pin is inserted into the guide sleeve.

[0020] The guide sleeve is a hollow round sleeve, and a small upper and large lower inclined surface is fixedly arranged at the bottom. The upper end of the positioning pin is small and the lower end is large, so that the inner hole of the guide sleeve and the positioning pin are conveniently engaged with each other.

[0021] As a further solution of the present invention: the jig includes a frame plate, the frame plate includes a sealing plate of the bottom plate and side plates arranged at both ends of the sealing plate, the sealing plate is fixedly connected to the jig bottom plate, the jig bottom plate and the side plates are provided with pins for fixing the jig bottom plate, and a connecting plate is provided between the side plate and the jig bottom plate.

[0022] The frame plate is provided with mounting holes on the side thereof, which match the positioning holes at the head and tail of the fixture bottom plate and are fixed by means of bayonet pins to prevent the fixture bottom plate and the frame plate from relative movement.

[0023] As a further solution of the present invention: a step groove is provided at the upper end of the jig bottom plate, a pad is connected to the upper end of the jig bottom plate, the cross-section of the side panel is C-shaped, a middle pad and side pads are provided in the side panel, and the side pads are located on the inner side of the wing panels on both sides of the side panels.

[0024] The side pads and the middle pads are higher than the base surface of the frame plate to prevent the aluminum shell from directly contacting the frame plate and causing damage.

[0025] As a further solution of the present invention: a hand push frame is arranged on one side of the frame, a handle is arranged on the hand push frame, a plurality of casters are arranged at the bottom of the frame, and a guide shaft and a buffer block are arranged on the outer side of the frame.

[0026] The guide shaft is conical and has a small protrusion. When the trolley approaches the required position, the guide shaft engages with the guide to fix the trolley to the required position. The buffer block protrudes from the frame. When the trolley collides with other objects, the buffer block contacts the frame before it plays a buffering and shock-absorbing role, thereby reducing damage to the aluminum shell of the trolley.

[0028] 1. The vehicle body and material frame of the present application adopt a modular design. The material frame is detachably connected with multiple jig material frames. The aluminum shell is placed in the material frame jig. When the aluminum shell model changes, only the corresponding jig material frame needs to be replaced. The vehicle body or bottom plate does not need to be changed, which greatly increases the universal performance. At the same time, after the material frame is loaded, the vehicle body can be reused, reducing the manufacturing cost and storage space of the aluminum shell.

[0029] 2. The body of the transfer trolley of the present invention forms a sliding groove through rollers and friction strips, and a screw is provided on the body. The material frame can slide in the sliding groove through an external motor and a screw drive, thereby realizing automatic loading, which is labor-saving and fast, and is conducive to improving production efficiency.
