[0002] In the field of LED chip manufacturing technology, various film materials are often needed to process LED chips. Therefore, the production of film materials is also an indispensable step in the production of LED chips. After the film material is produced, it needs to be demolded to remove the film material from the production jig.

[0003] In the prior art, the finished film material is generally sucked out from the silicon plate by a suction nozzle. However, due to the vacuum adsorption between the film material and the silicon plate, when the film material is sucked out, the silicon plate may be lifted up together, causing the risk of the silicon plate falling from a certain height. In the prior art, a demolding ring is generally placed between the film material and the silicon plate. When taking the film, the demolding ring is controlled to separate from the film material to break the vacuum between the film material and the silicon plate. However, due to the single structure of the demolding ring, when rising, it is sometimes impossible to separate the film material from the silicon plate, resulting in the inability to break the vacuum, and then when the film material is sucked out, the silicon plate is lifted up together.

[0027] See also Figures 1 to 3, shown is a mold turning machine in an embodiment of the utility model, including a placement platform 5, and a silicon plate 7 located above the placement platform 5, the silicon plate 7 is used to carry a film material 6, a silicon plate pressing ring 9 is provided at the edge of the silicon plate 7, the silicon plate pressing ring 9 includes a placement portion 91 located on the placement platform 5, and a pressing portion 92 located above the edge of the silicon plate 7, a demolding ring 8 is provided above the silicon plate pressing ring 9, the demolding ring 8 is used to enclose the film material 6, the demolding ring 8 includes a plurality of step portions 81 (only one in this embodiment) arranged in a stepped shape at the lower part of the inner wall thereof, the silicon plate 7, the pressing portion 92, and the step portion 81 are all tightly fitted with the film material 6.

[0028] It should be noted that the silicon plate pressure ring 9 may be in the shape of a closed ring or in the shape of a plurality of blocks arranged at intervals.

[0029] It can be understood that the present invention arranges a silicon plate pressing ring 9 on the silicon plate 7, and arranges a demolding ring 8 above the silicon plate pressing ring 9, so that the film material 6 is located between the silicon plate 7, the silicon plate pressing ring 9, and the demolding ring 8, and at the same time, the silicon plate pressing ring 9 is divided into a placing portion 91 and a pressing portion 92, the placing portion 91 is located on the placing platform 5, and the pressing portion 92 is located on the silicon plate 7. When the film material 6 is sucked up, the pressing portion 92 can limit the upward movement of the silicon plate 7 to prevent the silicon plate 7 from falling due to the upward movement;

[0030] By setting the lower part of the inner wall of the demolding ring 8 as a plurality of stepped portions 81 arranged in a step shape, when the demolding ring 8 is moved up to separate from the membrane material 6, the stepped portions 81 will lift the membrane material 6 more easily, and at the same time, the air will more easily enter the bottom of the membrane material 6 from the stepped portions 81, pass through the pressing portion 92, and finally enter the silicon plate 7, so as to better break the vacuum between the silicon plate 7 and the membrane material 6, and prevent the silicon plate 7 from being lifted up due to the vacuum not being broken when the membrane material 6 is sucked up.

[0031] Preferably, the film stripping ring 8 further includes an inclined portion 82 located at the upper portion of the inner wall thereof, the inclined portion 82 is inclined from bottom to top and from inside to outside, and the inclined portion 82 is in contact with the film material 6 .

[0032] It can be understood that by setting the inner upper part of the demolding ring 8 at an angle, since the membrane material 6 is flexible, when the stepped portion 81 lifts the membrane material 6, the periphery of the membrane material 6 is higher than the center of the membrane material 6, so that a gap appears between the periphery of the membrane material 6 and the inner wall of the demolding ring 8, and the inclined portion 82 can increase the gap, so that some air can enter between the membrane material 6 and the demolding ring 8 through the gap, thereby preventing the demolding ring 8 from being too tightly attached to the membrane material 6 and tearing the membrane material 6.

[0033] Preferably, the lowest stepped portion 81 of the demolding ring 8 is arranged close to the edge of the pressing portion 92 .

[0034] It can be understood that the most preferred setting method is that the pressing portion 92 is just pressed on the edge of the silicon plate 7 so that the silicon plate 7 will not be lifted up, and then the step portion 81 is set close to the pressing portion 92. In this way, when the demolding ring 8 is lifted, the air can reach the top of the pressing portion 92 from the bottom of the step portion 81 more quickly, and then enter between the membrane material 6 and the silicon plate 7 more quickly, thereby improving the efficiency of breaking the vacuum.

[0035] Furthermore, an adsorption assembly is provided above the film material 6, and the adsorption assembly includes a supporting plate 10, a plurality of suction nozzles 12 located below the supporting plate 10, and a first telescopic member for controlling the upward and downward movement of the supporting plate 10, wherein the first telescopic member controls the upward and downward movement of the supporting plate 10 so that the supporting plate 10 drives the suction nozzles 12 to suck up the film material 6.

[0036] It can be understood that after the stripping ring 8 rises and breaks the vacuum between the film material 6 and the silicon plate 7, the first telescopic member can be controlled to drive the carrying plate 10 to descend, so that the suction nozzle 12 under the carrying plate 10 sucks up the film material 6 to complete the film removal operation.

[0037] Furthermore, the adsorption assembly also includes an exhaust pipe 11 connected to the supporting plate 10, and the supporting plate 10 has a flow channel that passes through each of the suction nozzles 12. The exhaust pipe 11 is connected to an external exhaust device and provides adsorption force to the suction nozzles 12 through the flow channel.

[0038] Furthermore, a heating tube 4 is provided in the placement platform 5 , and the heating tube 4 is connected to an external heating device for heating the silicon plate 7 .

[0039] It can be understood that since glue is coated between the silicon plate 7 and the film material 6 , heating by the heating tube 4 is required to activate the glue.

[0040] Furthermore, the mold turning machine also includes a lifting component, which is fixedly connected to the demolding ring 8 and is used to control the demolding ring 8 to move up and down.

[0041] Specifically, a fixing hole 83 is provided in the demolding ring 8, and the lifting assembly includes a lifting top column 3 connected to the fixing hole 83, and a second telescopic member for controlling the up and down movement of the lifting top column 3, and the second telescopic member drives the lifting top column 3 to move up and down, so that the lifting top column 3 drives the demolding ring 8 to move up and down.

[0042] It can be understood that the upper part of the lifting column 3 is first fixedly connected to the demolding ring 8 through the fixing hole 83, and then the second telescopic member is started to control the lifting column 3 to rise, so as to lift the demolding ring 8, so that the demolding ring 8 drives the film material 6 to rise, thereby breaking the vacuum between the film material 6 and the silicon plate 7, and then the second telescopic member is controlled to descend to place the film material 6 flat, and then the suction nozzle 12 is controlled to descend to take out the film material 6.

[0043] More specifically, the second telescopic member includes a lifting cylinder 1 and a connecting portion 2 connecting the lifting cylinder 1 and the lifting top column 3 .

[0044] It can be understood that by connecting the telescopic part of the lifting cylinder 1 to the connecting part 2 and then connecting the lifting top column 3 through the connecting part 2, the telescopic part of the lifting cylinder 1 will drive the lifting top column 3 to rise and fall through the connecting part 2.

[0045] In summary, the mold turning machine in the above embodiment of the utility model is provided with a silicon plate pressure ring on the silicon plate, and a demolding ring is provided above the silicon plate pressure ring, so that the film material is located between the silicon plate, the silicon plate pressure ring, and the demolding ring, and the silicon plate pressure ring is divided into a placing part and a pressing part, the placing part is located on the placing platform, and the pressing part is located on the silicon plate, when the film material is sucked up, the pressing part can limit the upward movement of the silicon plate, and prevent the silicon plate from falling due to the upward movement;

[0046] By setting the lower part of the inner wall of the demolding ring as a plurality of stepped parts arranged in a step shape, when the demolding ring is moved up to separate from the membrane material, the stepped parts will lift the membrane material more easily, and at the same time, the air will more easily enter the bottom of the membrane material from the stepped parts, pass through the pressing part, and finally enter the silicon plate, so as to better break the vacuum between the silicon plate and the membrane material, and prevent the silicon plate from being lifted up due to the vacuum not being broken when the membrane material is sucked up.
