The production process of the quartz plate generally comprises the steps of mixing, press forming, curing and the like. Referring to fig. 1, in the curing process, trays of the transfer platform are stacked up and down on a ferry vehicle through a manipulator (provided with at least four grabs), the ferry vehicle slides into a baking oven, and a plurality of ferry vehicles are arranged in the baking oven side by side along the track direction. The quartz plate is solidified in the baking oven through hot air. After solidification, the ferry vehicle sequentially slides out of the baking oven, the tray is taken down layer by another mechanical arm (provided with a plurality of suckers), and the quartz plate is taken down from the tray and then is reused. The tray specifically includes two backup pads of rectangle glass board and rectangle glass board upper surface both sides, and the backup pad is perpendicular with rectangle glass board and is equipped with a plurality of ventilation holes on it. The quartz plate is arranged on the rectangular glass plate and is positioned between the two supporting plates, and the rectangular glass plate is arranged at the top of the supporting plates to realize lamination.

The applicant has found that, when using the aforementioned system for the production of quartz plates, the transfer process of the trays is very complex, requiring at least 2-3 robots (articulated robots), the trays being able to be placed in the oven only in a way that they are stacked first and then placed side by side in sequence by means of a ferry vehicle. Meanwhile, due to the structure of the tray, the baking box is uneven in hot air, the baking box can only be used for baking at low temperature for a long time, the quality of the obtained product is still poor, and the production efficiency is also influenced.

Example 2

On the other hand, referring to fig. 2 to 6, embodiments of the present invention provide a method for producing a quartz plate capable of improving production efficiency, which can be produced by using the system provided in embodiment 1. The method comprises the following steps: rotate bracket 17 to along controlling to and with transporting platform 11 butt joint, the manual work pushes away tray 2 to certain layer of bearing structure of bracket 17 by transporting platform 11, with two fixed knot that bracket 17 both sides construct locking with fixed tray 2. The walking car 15 is along controlling the dead ahead of motion to the griddle, with the bracket 17 rotatory to along the back to, through walking car 15 side to side motion and 16 up-and-down motion make certain layer bearing structure butt joint of bearing structure and griddle that have the tray 2 of treating drying (the quartz plate on it) on the bracket 17, the fixed knot of bracket 17 rear side constructs and opens, and the manual work pushes away tray 2 on the bracket 17 to the griddle, accomplishes back bracket 17 and returns initial position. By analogy, a plurality of trays 2 are fed into the toasting carriage in a rectangular array. During the return of the carriage 17 to the starting position, it may or may not be moved to the position with the tray 2 after baking is completed and transfer the tray 2 to the transfer platform 11. The transfer process, the manipulator can automatic action is transported, also can realize through the button operation panel by the manual work. In the embodiment, a special curing device is adopted, and high-temperature short-time baking can be adopted (the problems of over-baking and insufficient local baking due to local overheating can not occur).

In the prior art, because the hot air cannot be uniformly distributed, for a certain product, the prior art generally adopts long-time drying, for example, baking at 70 ℃ for 3 hours, which still causes good curing of resin at partial positions and poor curing of resin at partial positions; and adopt the device of this patent, can adopt high temperature fast drying, it can usually 80 ℃ toast 1 hour, can energy-conserving at least half the energy.

From the quality of product, the product resin solidification that adopts the solidification equipment of this patent to obtain is all better, and shock resistance is good (ball drop test (750 g steel ball, spline size 200mm, standard test), and the ball drop height of prior art is 470 and covers 520mm, adopts the device of this patent, and the ball drop height can reach 570 mm). Through visual inspection (monochromatic quartz slate), the device adopting the patent has better flatness than the prior art.

The results of testing 10 batches of products prepared using the curing apparatus are as follows; the bending strength is 40.2-42.1Mpa (spline 300mm 100 mm), the elastic modulus is 10530-. The product quality is very stable and meets or exceeds the national standard.

Further, 20 specimens (specimen 100 mm) were uniformly and randomly sampled on a quartz plate of 20mm thickness and 2m 0.6m, and the mohs hardness was measured; experiment 1 the curing device (baking at 80 ℃ for 1 hour) was used for baking; test 2 was baked using the existing curing apparatus (same as the other conditions of test 1, baking at 70 ℃ for 3 hours); the results are shown in table 1:
