Description

Technical Field

[0001] The present invention relates to the field of auxiliary technology of flat-plate hot pressing equipment, and more specifically to a fiber thermoplastic composite flat-plate hot pressing machine for a power battery cover. Background Art

[0014] Technical effects and advantages of the present invention:

[0015] 1. The present invention is provided with a temperature control component. After placing the fiber thermoplastic composite on the press plate, the pipe valves on the liquid inlet pipe and the liquid return pipe are closed, and the heating power supply supplies power to the heating plate to start heating the heat exchange oil filled in the compartment, so that the press plate starts to heat up, thereby heating the fiber thermoplastic composite. After the hot pressing work of the fiber thermoplastic composite is completed, the pipe valves on the liquid inlet pipe and the liquid return pipe are opened, and the pressure pump is started to pump the unheated heat exchange oil in the liquid storage box into the compartment through the liquid inlet pipe. The hot oil in the compartment flows back to the inside of the liquid storage box through the liquid return pipe. After the oil is mixed, the temperature drops rapidly. After the oil in the compartment is renewed, the press plate and the heating plate can be quickly cooled. While the device uses the oil medium for heating, it achieves its rapid cooling effect by directly mixing the hot and cold oil mediums.

[0016] 2. The present invention is provided with a material taking component. When the fiber thermoplastic composite material on the pressing platen is hot-pressed, the material taking motor drives the spline shaft to rotate. The rotation of the spline shaft drives the spline sleeve and the material taking box to rotate, so that the long end of the material taking box is screwed into the top of the pressing platen. At this time, the material taking electric cylinder drives the lower pressing hollow shaft to push the spline sleeve downward. The spline sleeve moves downward on the shaft body of the spline shaft, thereby driving the material taking box to move downward, so that the high temperature resistant suction cup contacts downward and presses the fiber thermoplastic composite material placed on the pressing platen. During the whole process, the fan starts to exhaust air outward, so that the inside of the dust collection box is in a negative pressure state. The material taking box is connected with the dust collection box through a connecting pipe, so that the air flow is sucked from the plate hole. When the high temperature resistant suction cup contacts and presses the fiber thermoplastic composite placed on the press plate, the high temperature resistant suction cup firmly sucks the fiber thermoplastic composite, and drives the material picking box to rotate again through the material picking motor, so that the sucked fiber thermoplastic composite rotates to the top of the placement slot, and after the material picking box moves downward and turns off the fan, the fiber thermoplastic composite is automatically placed in the placement slot, and its automatic unloading function is realized in this way. At the same time, in the process of sucking the fiber thermoplastic composite, the dust particles on the surface of the press plate and the fiber thermoplastic composite will be sucked into the dust collection box through the disc holes with the airflow, and the dust particles are intercepted and filtered by the filter plate, and the cleaning function of the device is realized in this way.

[0032] Reference Figure 5-Figure 7The material picking component 3 includes a front plate 301, which is fixedly mounted on the front end of the mounting plate 106, and a material picking electric cylinder 302 is fixedly mounted on the upper end of the front plate 301, and a lower pressure hollow shaft 303 is fixedly connected to the bottom driving end of the material picking electric cylinder 302, and a bearing 304 is sleeved on the bottom end of the lower pressure hollow shaft 303, and a spline sleeve 305 is sleeved on the inner ring of the bearing 304, and a material picking box 306 is fixedly sleeved on the outer side of the bottom end of the shaft body of the spline sleeve 305, and a bottom mounting plate 307 is fixedly mounted on the bottom of the material picking box 306, and evenly distributed high temperature resistant suction cups 308 are fixedly mounted on the bottom of the bottom mounting plate 307, and disc holes 309 are opened on the high temperature resistant suction cups 308, and the inner side of the shaft body of the spline sleeve 305 A spline shaft 310 is movably sleeved, the material taking box 306 is fixedly connected with a connecting pipe 311, a placement groove 312 is fixedly installed on the front end surface of the base 101, a material taking motor 313 is fixedly installed on the front end surface of the base 101, and the driving end of the material taking motor 313 is fixedly connected to the shaft body of the spline shaft 310, a dust collection box 314 is fixedly installed on the front end surface of the base 101, and three evenly distributed fans 315 are fixedly installed on the outer side of the bottom end of the dust collection box 314, and a filter plate 316 is fixedly installed inside the dust collection box 314, and the installation height of the filter plate 316 is higher than that of the fan 315, and a box plate 317 is fixedly installed on the top of the dust collection box 314, and the box plate 317 is fixedly connected to the pipeline of the connecting pipe 311;

[0033] In this embodiment, after the fiber thermoplastic composite material on the press plate 103 is hot-pressed, the material taking motor 313 drives the spline shaft 310 to rotate, and the rotation of the spline shaft 310 drives the spline sleeve 305 and the material taking box 306 to rotate, so that the long end of the material taking box 306 is screwed into the top of the press plate 103. At this time, the material taking electric cylinder 302 drives the downward pressing hollow shaft 303 to push the spline sleeve 305 downward, and the spline sleeve 305 moves downward on the shaft body of the spline shaft 310, thereby driving the material taking box 306 to move downward, so that the high temperature resistant suction cup 308 contacts and presses the fiber thermoplastic composite material placed on the press plate 103.

The device uses the oil medium for heating and achieves its rapid cooling effect by directly mixing the hot and cold oil medium. When the fiber thermoplastic composite on the press plate 103 is hot-pressed, the material taking motor 313 drives the spline shaft 310 to rotate. The rotation of the spline shaft 310 drives the spline sleeve 305 and the material taking box 306 to rotate, so that the long end of the material taking box 306 is screwed into the top of the press plate 103. At this time, the material taking electric cylinder 313 02 drives the hollow shaft 303 downward to push the spline sleeve 305, and the spline sleeve 305 moves downward on the shaft body of the spline shaft 310, thereby driving the material box 306 to move downward, so that the high temperature resistant suction cup 308 contacts and presses the fiber thermoplastic composite placed on the press plate 103 downward. During the whole process, the fan 315 starts to exhaust air outward, so that the interior of the dust box 314 is in a negative pressure state. The material box 306 is connected with the dust box 314 through the connecting pipe 311, so that the air flow is sucked in from the disc hole 309. When the high temperature resistant suction cup 308 contacts and presses the fiber thermoplastic composite placed on the press plate 103 downward, the high temperature resistant suction cup 308 The suction cup 308 firmly holds the fiber thermoplastic composite, and drives the material picking box 306 to rotate again through the material picking motor 313, so that the sucked fiber thermoplastic composite rotates to the top of the placement groove 312. After the material picking box 306 moves downward and turns off the fan 315, the fiber thermoplastic composite is automatically placed in the placement groove 312. In this way, its automatic unloading function is realized. At the same time, in the process of sucking the fiber thermoplastic composite, the dust particles on the surface of the press plate 103 and the fiber thermoplastic composite will be sucked into the dust collection box 314 through the disc hole 309 with the air flow, and the dust particles are intercepted and filtered by the filter plate 316.
