Description

Technical Field

[0001] This utility model relates to the field of glass hot bending processing technology, and in particular to a multi-sensor temperature control mold for use in glass hot bending forming apparatus. Background Technology

[0002] With the development of flexible displays, products with diversified designs, ranging from typical flat panels to partially curved panels (such as U-shapes, C-shapes, and S-shapes), based on the geometric characteristics of the display, are attracting increasing attention. These products not only meet users' convenience requirements but also highlight the product's design features. Traditional hot bending technology mostly requires molds for pressure forming, and the heat source is relatively singular, making it inconvenient to precisely control the temperature gradient in different areas. However, with changing market demands, curved glass shapes are becoming increasingly complex, with U-shapes, C-shapes, and S-shapes constantly emerging, which are difficult to achieve using traditional upper / lower molds (convex / concave molds). Utility Model Content

[0003] The main purpose of this utility model is to overcome the above-mentioned shortcomings and deficiencies of the prior art and provide a multi-sensor temperature control mold.

[0004] A multi-sensor temperature-controlled mold is used in a glass hot bending forming device. The temperature-controlled mold is mounted on a rotating module, and a glass part is placed on the temperature-controlled mold. The rotating module drives the temperature-controlled mold to rotate. The multi-sensor temperature-controlled mold includes: a mold body, at least one sub-mold, at least one first heating element, at least one second heating element, and multiple temperature sensors. The mold body is rectangular, and the outer edge of the sub-mold is arc-shaped. The sub-mold is detachably mounted on the mold body. The first heating element is mounted on the mold body and heats the glass part. The second heating element and the temperature sensors are mounted on the sub-mold. The temperature sensors detect the temperature of the glass part located on the sub-mold. The second heating element adjusts and locally maintains the temperature of the glass part located on the sub-mold based on the data from the temperature sensors.

[0005] This invention allows for the detachable installation of sub-molds of different shapes on the main mold body, satisfying the hot bending forming of glass parts of different shapes. The first heating element heats the glass part, and the temperature sensing element built into the sub-mold provides online temperature sensing. This, in turn, controls the second heating element to locally heat areas with uneven temperature within the sub-mold, improving the uneven heating caused by using the first heating element alone.

[0006] In one embodiment, the number of sub-molds is two, and the two sub-molds are detachably mounted at both ends of the mold body.

[0007] In one embodiment, the outer edge curvature of the two sub-molds is consistent.

[0008] In one embodiment, the outer edge curvatures of the two sub-molds are inconsistent.

[0009] In one embodiment, the mold body has an installation groove, the sub-mold has a plug-in post, the plug-in post is inserted into the installation groove, and the end of the sub-mold coincides with the end of the mold body.

[0010] In one embodiment, the number of the first heating elements is four, and the mold body has four mounting holes, with each of the first heating elements inserted into the mounting hole.

[0011] In one embodiment, both the first heating element and the second heating element are electric heating rods, and the heating power of the first heating element and the second heating element are different.

[0012] In one embodiment, the number of the second heating element is one, and a plurality of the temperature sensors are arranged in an array around the second heating element.

[0013] In one embodiment, the mold body is provided with a plurality of air holes.

[0014] This utility model has the following beneficial effects: by detachably installing sub-molds of different shapes on the mold body, it can meet the hot bending forming of glass parts of different shapes. The first heating element heats the glass parts and the temperature sensing element built into the sub-mold can perform online temperature sensing, thereby controlling the second heating element to locally heat the areas with uneven temperature in the sub-mold, improving the unevenness of heating when the first heating element is used alone, achieving high-precision heating, improving the forming quality, and increasing the yield of finished products.

[0028] Example 1

[0029] Please see Figure 1This utility model provides a multi-sensor temperature-controlled mold 100 for use in a glass hot bending forming device. The glass hot bending forming device includes the multi-sensor temperature-controlled mold 100, a rotating module 200, a worktable 300, a first heating module 400, and a second heating module 500. The multi-sensor temperature-controlled mold 100 is mounted on the rotating module 200, which is mounted on the worktable 300. A glass part 600 is placed on the multi-sensor temperature-controlled mold 100 and rotates... Module 200 drives the multi-sensor temperature-controlled mold 100 to rotate. The first heating module 400 is mounted on both sides of the multi-sensor temperature-controlled mold 100 and heats both the mold and the glass component 600 as a whole. The second heating module 500 is mounted on the worktable 300 and positioned above the multi-sensor temperature-controlled mold 100. While heating the glass component 600, the second heating module 500 can also detect the degree of bending of the glass component 600. Heating the glass component 600 and the multi-sensor temperature-controlled mold 100 through multiple heat sources allows for targeted heating of the desired area, achieving high-precision heating. Specifically, the first heating module 400 is an infrared heating module, and the second heating module 500 is a laser heating module. The second heating module 500 rapidly heats the hot-bending area of ​​the glass component 600 through scanning.

[0030] For more details, please refer to Figure 2 and Figure 3 The multi-sensor temperature control mold 100 includes a mold body 1, two sub-molds 2, four first heating elements 3, six second heating elements 4, and multiple temperature sensors 5. The mold body 1 is rectangular, and the outer edge of the sub-molds 2 is arc-shaped. The two sub-molds 2 are detachably mounted on both ends of the mold body 1. The first heating elements 3 are mounted on the mold body 1 and heat the glass part 600. The second heating elements 4 and the temperature sensors 5 are mounted on the sub-molds 2. The temperature sensors 5 are located on the parts of the sub-molds 2 where the glass part 600 needs to be bent, so as to facilitate timely detection when the glass part 600 is bent. The temperature sensors 5 detect the temperature of the glass part 600 located on the sub-molds 2. The second heating elements 4 adjust the local temperature of the glass part 600 located on the sub-molds 2 and perform local heat preservation based on the data from the temperature sensors 5.

[0031] For more details, please refer to Figure 3 In this embodiment, the outer edges of the two sub-molds 2 have the same curvature, and the outer edges of the sub-molds 2 are semi-circular. By rotating the multi-sensor temperature control mold 100, the complex C-shaped hot bending of the glass part 600 is achieved.

[0032] Preferably, please refer to Figure 4 and Figure 5In another embodiment of this example, the outer edges of the two sub-molds 2 have the same curvature, and the outer edge of the sub-mold 2 is a semi-elliptical arc shape. The outer edge of the sub-mold 2 can have different shapes to meet different hot bending shape requirements.

[0033] For more details, please refer to Figure 3 The mold body 1 has an installation groove 11, and the sub-mold 2 has a plug-in post 21. The plug-in post 21 is inserted into the installation groove 11, and the end of the sub-mold 2 coincides with the end of the mold body 1. It can be understood that the number of installation grooves 11 and plug-in posts 21 corresponds. This embodiment uses one installation groove 11 and one plug-in post 21 for illustration, but there can also be multiple. At the same time, since multiple second heating elements 4 and multiple temperature sensing elements 5 need to be arranged in the sub-mold 2, it is the optimal choice to set the plug-in post 21 on the sub-mold 2. Alternatively, the installation groove can be set on the sub-mold 2 and the plug-in post can be set on the mold body 1, all of which are within the scope of the concept of this utility model.

[0034] For more details, please refer to Figure 3 The mold body 1 has four mounting holes 12, and each first heating element 3 is inserted into a mounting hole 12. Preferably, the first heating element 3 and the second heating element 4 are both electric heating rods, and the heating power of the first heating element 3 and the second heating element 4 are different. The heating power of the first heating element 3 is greater than that of the second heating element 4. Preferably, the mold body 1 has a plurality of air holes (not shown in the figure), which are used to generate negative pressure to assist in the adsorption of the glass part 600.

[0035] Example 2

[0036] Please see Figure 6 This utility model provides a multi-sensor temperature control mold 100, whose structure is basically the same as that of Embodiment 1, except that the outer edge curvatures of the two sub-molds 2 are different, so that different shapes can be hot-bent and formed on the same mold. Preferably, there is one second heating element 4, and multiple temperature sensors 5 are arranged in an array around the second heating element 4.

[0037] This invention allows for the detachable installation of sub-molds 2 with different shapes on the mold body 1, enabling hot bending of glass parts 600 in different shapes. The first heating element 3 heats the glass parts 600, and the temperature sensor 5 built into the sub-mold 2 senses the temperature online. This allows the second heating element 4 to be controlled to locally heat areas with uneven temperatures within the sub-mold 2, thus improving the uneven heating caused by using the first heating element 3 alone.

[0038] In use, the multi-sensor temperature-controlled mold 100 of this invention is used after the first heating module 400 preheats the glass part 600. Simultaneously, the second heating module 500 rapidly heats a localized area of ​​the glass part 600, while the rotation module 200 drives the multi-sensor temperature-controlled mold 100 to rotate and bend it. The laser emitted by the second heating module 500 can detect the degree of bending of the glass part 600 and the degree of adhesion between the bent glass part 600 and the multi-sensor temperature-controlled mold 100. When there is a certain gap between the glass part 600 after hot bending and the multi-sensor temperature control mold 100, the temperature of the second heating module 500 is increased, and the second heating element 4 is controlled to heat the hot bending area until the degree of fit between the glass part 600 and the multi-sensor temperature control mold 100 after hot bending meets the requirements; after hot bending is completed, the multi-sensor temperature control mold 100 is reset, and the hot bending area of ​​the glass part 600 is locally heat-preserved by the second heating element 4; after heat preservation is completed, the second heating element 4 is turned off.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
