Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of automobile interior production, and particularly relates to a production method and a composite tool for a spare tire cover plate. BACKGROUND

[0002] The spare tire cover plate is an automobile interior part, which comprises a backing plate and a surface decoration material covering the backing plate, and the two are combined by glue. The combination of the surface decoration material and the backing plate is an important step in the production process. In order to realize accurate positioning, a composite tool is generally used to realize the positioning and combination of the backing plate and the surface decoration material.

[0003] Problems of the prior art:

[0004] In the production process of the traditional spare tire cover plate, the backing plate and the felt cloth need to be combined and formed by adhesion. The existing cover plate combination and adhesion equipment needs manual laying of felt cloth and manual installation of the backing plate one by one. Then, the hot melt adhesive on the surface of the felt cloth is melted by using the heating mechanism of the equipment. Finally, the backing plate and the felt cloth are pressed and adhered by the equipment. In this way, the work of raw material replenishment and the work of taking out the finished product need to be done manually, which cannot liberate manpower, and the time of one working cycle is long and the work efficiency is low. In addition, the existing cover plate combination and adhesion equipment can only directly press and adhere the backing plate and the felt cloth. This adhesion method cannot effectively avoid and solve the problem of air bubbles between the two. If the air bubbles in the adhesion part stay for a long time, the glue in this part will dry and crack, the adhesion of this part of the cover plate is not effective, and the quality of the finished product is reduced.

DETAILED DESCRIPTION

[0038] In order to make the purposes and advantages of the present application more clear, the present application is specifically described below in conjunction with embodiments.

After the hot melting plate 401 is completely returned, the next lining plate 12 can be automatically transported into the material groove one 404 by the belt conveyor one 201, and the lining plate 12 is adjusted to the specified position by the positioning member 5 during the transportation process;

[0041] S2: The material plate 801 carries the felt and moves along the through rail two 7 to above the covering table 601. At the same time, the last finished product cover plate is lowered by the pressing plate 609 to the material groove two 802. After the felt is placed on the surface of the covering table 601, the material plate 801 is returned together with the last finished product. After the material plate 801 is completely returned, the finished product cover plate in the material groove two 802 is taken away by the belt conveyor two 10;

[0060] The second step is to work the track machine 2 805 to control the movement of the material plate 801, the suction cup at the bottom of the material plate 801 carries the felt cloth and moves along the track 2 7 to above the covering table 601, and the material groove 2 802 moves to the bottom of the pressing plate 609, then the finished product cover plate of the last covering is lowered by the pressing plate 609 to the inside of the material groove 2 802, after the felt cloth is placed on the surface of the covering table 601, the material plate 801 moves back to the original position together with the last finished product, as shown in the figure, after the material plate 801 is completely reset, the belts at both ends of the belt conveyor 2 10 extend into the slot 803, and finally the finished product cover plate in the material groove 2 802 is taken away by the belt conveyor 2 10; Figure 6

[0061] The third step is that in the process of resetting the material plate 801, the hot melting plate 401 immediately carries the lining plate 12 into the inside of the cover plate vacuum covering machine 6, then the hot melting plate 401 heats the felt cloth placed on the surface of the covering table 601, the heat generated by the hot melting plate 401 melts the hot melt adhesive on the surface of the felt cloth and generates adhesion, in this process, the pressing plate 609 just moves down to suck the lining plate 12 and then takes the lining plate 12 away from the inside of the material groove 1 404;

[0062] ​Fourth step, hot melt plate 401 immediately after heating reset, followed by repeating the first step of the process, then, hydraulic cylinder one 606 and hydraulic cylinder two 608 work together to make the pressure plate 609 down, the pressure plate 609 down with the liner 12 and felt adhesive, followed by four side cylinder one 603 work together and make the edge plate push plate 604 extrusion edge felt, finally complete the edge of the cover plate adhesive work;

[0063] Fifth step, in the edge work, hydraulic cylinder three 614 work to make the vacuum cover 612 down, through the vacuum cover 612 cover plate 609 and each sealing ring 602, just finished the cover plate of the cover and edge work is also covered by the vacuum cover 612, at this time the sealing gasket 613 fit cover table 601 surface and edge push plate 604 side wall, sealing strip 605 and sealing ring 602 fit, so that the vacuum cover 612 cover space for sealed space, then start the air pump 11 to carry on the exhaust, reduce the vacuum cover 612 internal sealed space in the air pressure, in the process of air pressure gradually reduces, the felt and the liner 12 between the bubble can be quickly through the felt gap and the gap between the liner 12 exhaust, exhaust after the cover plate production forming, finally by the pressure plate 609 with the finished cover plate up.

[0064] The above only is the preferred embodiment of the present application, should be noted that for the ordinary skilled in the art, without departing from the principles of the present invention, can also make a number of improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application. The structure, device and operation method are not specifically described and explained in the present application, such as no special description and limitation, are implemented according to the conventional means in the art.
