Description

Technical Field

[0001] The invention relates to the technical field of automobile battery pack shell processing, and in particular to a special-shaped aluminum shell plate film pasting device for an automobile battery pack. Background Art

[0002] With the development of the new energy electric vehicle industry, the battery pack in electric vehicles has become a more important manufacturing component. At present, the automotive battery pack is mainly composed of a frame, a battery module and an aluminum shell plate, among which there are more bent aluminum shell plates. During assembly, multiple battery modules are placed in the frame and separated by two vertical aluminum shell plates. These aluminum shell plates need to be equipped with insulating films to avoid direct contact with other electrical components. When applying the film, the aluminum shell plate and the insulating film are generally placed in the mold at the same time, and then sent to the heating equipment for heating to make the insulating film and the aluminum shell plate fit tightly.

[0003] However, many of the devices mentioned above that are used to apply film to special-shaped aluminum shell plates for automotive battery packs require personnel to wait for the equipment and mold to cool down after the aluminum shell plates and insulating films are heated and applied in the mold through electric heating before they can open the mold to re-take the materials and fill them. When refilling for hot processing, the heating equipment and mold must be readjusted to a suitable temperature, resulting in limited continuous production capacity and low efficiency, which is not suitable for large-scale production and processing.

[0004] Based on this, the present invention designs a film-laminating device for special-shaped aluminum shell plates of automobile battery packs to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a film-laminating device for special-shaped aluminum shell plates of automobile battery packs to solve the above-mentioned technical problems.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a film-sticking device for special-shaped aluminum shell plates of automobile battery packs, comprising: a main frame; a cooling rack and a plurality of heating racks are respectively fixed on the top of the main frame, a first gear disc rack and a second gear disc rack are respectively rotatably connected at both ends of the main frame, a tooth chain is connected between the first gear disc and the second gear disc, a plurality of connecting plates are fixed on the outer wall of the tooth chain in sequence, a bottom mold is fixed on the outer wall of the connecting plate, a hydraulic cylinder is fixed on the heating rack and the top of the cooling rack, a driving shaft of the hydraulic cylinder is vertically downwardly connected to a mounting plate, an electric heating plate is fixed on the bottom of the mounting plate of the heating rack and the top of the main frame opposite thereto, a top mold is fixed on the outer wall of the electric heating plate of the heating rack, and a cold row plate is fixed on the bottom of the mounting plate of the cooling rack and the top of the main frame opposite thereto.

[0007] Preferably, a plurality of special-shaped mold grooves are sequentially opened on the top of the bottom mold, matching aluminum shell plates and insulating films are arranged in the special-shaped mold grooves, a through opening is opened along the special-shaped mold grooves on the top of the bottom mold, a push rod is slidably connected in the through opening of the bottom mold, and a plurality of plug rods are sequentially fixed to the bottom of the top mold.

[0008] Preferably, a spring is fixed between the push rod and the bottom mold, and the push rod and the insert rod are both L-shaped and have matching inclined chamfers on their outer walls.

[0009] Preferably, the toothed discs of the first toothed disc frame and the second toothed disc frame are symmetrical to each other, and both ends of the first toothed disc frame are rotatably connected to the outer wall of the main frame body.

[0010] Preferably, symmetrical placement sleeves are fixed to the outer wall of the main frame, and the two ends of the second gear disc frame are rotatably connected to the two placement sleeves respectively.

[0011] Preferably, the outer walls of the two placement sleeves are provided with threaded holes, and bolts can be connected through the threaded holes to control the second gear disc frame.

[0012] Preferably, a motor is fixed to the outer wall of the main frame, and one end of the motor transmission shaft is fixedly connected to one end of the first gear disc frame.

[0013] Preferably, guide rods are slidably disposed on the outer walls of the heating rack and the cooling rack, and one end of the guide rods of the heating rack and the cooling rack is respectively fixed to the outer walls of the mounting plates below each.

[0014] Preferably, an outer cover covering the heating rack and the cooling rack is fixed on the top of the main frame.

[0015] Preferably, a conveyor belt is provided at one end of the main frame at the bottom of the second gear disc frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects: First, the first gear disc rack and the second gear disc rack can simultaneously drive multiple bottom molds to circulate around multiple heating racks and cooling racks through a gear chain. One bottom mold can place multiple products at the same time. After a bottom mold enters the initial heating rack, the personnel can place the aluminum shell plate and the insulating film in the special-shaped mold groove of the bottom mold at the next waiting position, and then circulate into the heating rack and the cooling rack in turn for film laminating processing, which greatly improves the continuous production capacity and efficiency, and is suitable for mass production and processing; Secondly, the cooling rack and the cooling plate of the main frame can quickly cool down the bottom mold. After the cooling is completed, as the tooth chain rotates, the bottom mold will tilt on one side of the second toothed disc rack, so that the aluminum shell plate with the insulating film in the bottom mold falls to the conveyor belt for guided output, without manual material removal by personnel, saving manpower; Thirdly, the insertion rod of the top mold can be inserted into the reciprocating push rod in the top-moving bottom mold to press the insulating film of the bent edge of the special-shaped aluminum shell plate in the bottom mold tightly, so that the insulating film can wrap the aluminum shell plate more stably and tightly during heating; Fourthly, when the toothed chain is long and passes through the heating rack for operation, the toothed chain expands slightly. The bolt in the threaded hole of the adjustable mounting sleeve can be adjusted so that one end of the bolt rests against one end of the second toothed disc rack to straighten and tighten the slightly expanded toothed chain again to avoid the toothed chain being unusable due to the thermal effect expansion.
