The required glass components. However, the preheating zone towel, the glass has not been softened, can not be applied too much pressure, to avoid causing the glass material, but the upper heating plate must be in contact with the difficult amount to achieve the best heating "the sacred (four) job station plus The fixed position of the wire, but the glass mold is made, it belongs to the high temperature process, the high temperature coefficient of the money material is not w grip, which makes it difficult to set the position and setting of the hot plate on the leaf nose. Keep the _ root fine on the 34, all break In the pre-aged wealth and the upper heating plate, the glass becomes the right-touch heating without being _, and has the advantages of simple process, etc., which is an urgent problem to be solved for the equipment industry. 5 200837024 [Summary of the Invention] The main object of the present invention is to provide a molding apparatus for pressure sensing, which uses a rolling method instead of a conventional positioning method to control the position of the upper heating plate to ensure that the upper heating plate is in contact with the mold while ensuring It is avoided that the glass father is broken by excessive pressure. Further, since the concept of the present invention is to replace the conventional positioning method by using a constant pressure method, the height difference of different molds can be ignored. The glass is not ruptured or unevenly heated when heated, and can effectively improve the process yield and shorten the heating time. Therefore, in order to achieve the above object, the pressure sensing control molding apparatus disclosed in the present invention has a glass heating. The heating zone includes a preheating zone, a lens forming zone, a lens cooling zone, and the like, wherein the preheating zone comprises a pneumatic cylinder, and the upper heating plate is driven by the pneumatic cylinder; and the upper heating plate holds the mold a heating plate, and a pressure sensor disposed on the upper heating plate, for measuring the pressure applied to the fixture by the upper heating plate, and performing the returning to the position of the heating plate, which is different from the conventional use The molding device of the positioning control, the molding device of the invention can more effectively avoid the occurrence of the crushing, and can improve the wire laying and increase the forming speed. The mirror forming area of the nuclear equipment of the invention can also be provided with a pressure sensing chamber, The amount of the heating plate on the forming zone is controlled by the amount. In addition, the mirror field can also be provided without pressure sensing, and the pressure sensing feedback control is applied. The larger the force is that the lens of the mirror forming zone has been deformed and softened, so the pressure condition 200837024 can effectively improve the processing rate of the lens to the lens and shorten the processing time of the lens. By the dynamics provided according to the present invention, It is indeed possible to control the position of the upper heating plate to hold the mold, so that the method according to the invention has the advantages of avoiding glass breakage, slightly heating, and effectively improving the process yield and shortening the heating time, compared to the conventional positioning hot plate method. - The following detailed description of the features and advantages of the present invention in the embodiments of the present invention is sufficient to enable the skilled person to understand the technology of the present invention and to provide a basis for the contents of the present invention. The patents and the related art can easily understand the related objects and advantages of the present invention. [Embodiment] ^ Ma has a further understanding of the object, structure, features, and functions of the present invention. The system is as follows. Description of the present invention. The description of the present invention is based on the principle of the present invention, and the scope of the patent application of the present invention is further explained. Ming (4) "+1" is a schematic diagram of a molded device according to the concept of (4). For the convenience of the concept of the present invention, in the "i-th diagram", three pre-two (preheating zone la, preheating zone ib and preheating zone lc), _ lens forming zone 3 of 5C) are included. 1 lens cold section ^ (lens cooling zone 5 & lens cooling zone 5b and lens cooling zone anti-correction and other seven pressure sensing control molding equipment as an example, but in the real = use, can also be A molding apparatus having one, three or five different number of process zones, such as a preheating zone, a lens forming zone and a lens cooling zone, can be applied to the concept of the invention. On the other hand, the molding equipment In many preferred embodiments, a glass preform that is linked together with a glass preform is used as an example. As shown in FIG. 1, each processing zone of the molding apparatus mostly includes a pneumatic cylinder 7 And the upper heating plate 9 joined thereto; the lower heating plate n and the base 13 thereof. The cooker 15 is from the preheating zone la, the preheating zone lb, the preheating zone lc, the lens forming zone 3, and the lens lining zone 5a The lens cooling zone 5b and the lens cooling zone 5c are sequentially transferred in each process stage. The above-mentioned pneumatic cylinder 7 is a positioning device, and the private pressure is applied to the hot plate 9 to the fixed position to hold the mold 15 □ together with the lower heat plate 以 to the glass. The pre-opening body 31 is heated, formed, cooled, etc., and the lens 33 is 'each' of each set of molds 15 moving between each process zone, sometimes due to the mold processing, the height will be There are some small differences. Therefore, if (4) the method of setting the heating plate 9-bit i has ls contact, sometimes the difference in the height of the different molds will be different, resulting in uneven contact between the upper heating plate 9 and the mold 15. The age of the glass is uneven or the heating time is longer. ..., here, the positioning device of the concept of the present invention is modified. [Application # The ink force when the mold 15 is applied by the upper heating plate 9 is measured, and the feed control pressure is adjusted to increase the adjustment _ 9 s position. , the technical shooting type may include a no-h, a surface area lb, a two-zone sensor 17 for measuring the upper heating plate 9 to be applied to the mold: l JE hunting, the whole heating plate 9 Position, and reach the pre-shaped shape of the broken glass; 200837024 31 Constant pressure control during processing. Therefore, by adjusting the pressure of the upper heating plate 9 within the tolerance of the glass pressure, the glass preform 31 can be placed in the preheating zone u, the preheating zone b, and the surface 11 The glass is broken due to a poor health control system or a difference caused by the inaccuracy of the work of the mold 15. Fig. 2 is a schematic circuit diagram showing the pressure-measuring pressure of the pressure sensor side of the present invention. Wherein, three sets of pressure sensors π are respectively disposed in the preheating zone la, the preheating zone lb, and the heating plate 9 above the preheating zone 1C, whereby the pressure of the side and the upper heating plate 9 is used, and the instantaneous pressure data is used. The electrical connection mode is transmitted to a control woven device, and the control device 19 adjusts the internal pressure of the pneumatic cylinder 7 through the adjustment valve 2ι according to the parameters of the actual process, so as to accurately control the pressure applied to the mold 上 by the upper heating plate 9 and the glass pre- Constant pressure control during processing (not shown). ▲ The operation flow of the preferred embodiment of the present invention is: a human body or a mechanical arm from the glass preform placement area, and a pre-formed glass preform 31 having a similar shape volume and a cavity volume error (for example) is obtained. Fig. 1 shows "in the mold 15 after processing, and the mold 15 is composed of an upper mold and a lower mold, and the glass preform 31 is placed between the upper mold and the lower mold for heating; The mechanism gradually heats the mold 15 and the lion body 31 to the preheating zone la, the preheating zone lb and the preheating zone lc of the equipment. At this time, when the upper heating plate 9 presses the die 15, the system is based on The value measured by the sensor 17 is feedback-adjusted to adjust the position of the upper heating plate 9 or the standby position; after the predetermined temperature is set, the shifting transport mechanism 15 is used to move the job with the foot body 31 to make The glass preform 31 is softened and then applied to form a lens to form a lens. Then, the mold 15 which is formed into a lens of the 200837024 is moved to the lens cold portion 5a and the lens cooling portion 5b together with the lens 33. Lens cooling zone 5c gradually decreases Cooling, then 33 of the finished lens can be obtained. In view of the above, since the molding apparatus according to the concept of the present invention is provided with a pressure sensor, the pressure value of the upper heating plate applied to the mold can be measured, so that the pressure system and the pressure of the butterfly are only required to be produced. In the case of less than the processing pressure that the glass can withstand, no glass breakage will occur. In addition, because the pressure control will not be different due to the difference in mold height, according to the hair _ read, it can also ensure that the upper heating plate is in contact with the mold, so it can avoid the scalping caused by the difference in the moldness of each group (four) is heating Uneven county can effectively improve process yield and shorten heating time. , &, step-by-step, because of the money and distracting, it is necessary to solve the problem of uneven heating of the mold caused by the uneven height, so that the tolerance of the error between the molds in the mold glass process can be improved. The present invention has been disclosed in the foregoing embodiments, and is not intended to limit the scope of the invention, and the invention is modified and modified.
