[0029] The following is combined with Figure 1-6 The present invention is described in further detail.

[0030] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0031] Example 1: See Figure 1-6 As shown, a demoulding device for LIPO encapsulated screen is shown. The mold 100 includes a male mold 1001 and a female mold 1002. The two sides of the male mold 1001 are respectively provided with clamping plates 1003 for buckling on the two sides of the female mold 1002.

[0032] Combination Figure 1As shown, the demoulding equipment includes a machine 4, on which are arranged upper and lower mold mechanisms 1, a demoulding mechanism 2 and a material discharge mechanism 3. The upper and lower mold mechanisms 1 are used for loading the fully loaded mold 100 and for discharging the unloaded mold 100. The demoulding mechanism 2 includes a demoulding assembly 21 for opening the clamping plate 1003 and a gripping assembly 22 for grabbing the male mold 1001. The material discharge mechanism 3 is used for discharging the screen after demoulding. In this way, the demoulding assembly 21 can automatically open the clamping plate 1003, and the gripping assembly 22 can grab the male mold 1001 and realize its relative separation from the female mold 1002. There is no need to manually disassemble the mold 100, which can not only improve the efficiency of discharging the screen, but also save labor costs.

[0033] In this embodiment, the upper and lower mold mechanisms 1 include a conveying assembly 11, which includes two belt conveyors 111 arranged side by side along the width direction of the machine 4. The two belt conveyors 111 are respectively a first belt conveyor for inputting a fully loaded mold 100 and a second belt conveyor for outputting an unloaded mold 100. The first belt conveyor and the second belt conveyor both extend along the length direction of the machine 4 and have opposite conveying directions. The fully loaded mold 100 and the unloaded mold 100 can be conveyed on the first belt conveyor and the second belt conveyor in opposite conveying directions, respectively, effectively avoiding interference between the fully loaded mold 100 and the unloaded mold 100 during the conveying process.

[0034] like Figure 1-2 As shown, there are two demoulding mechanisms 2 and both are arranged side by side along the width direction of the machine table 4. Both demoulding mechanisms 2 are located on the side of the conveying direction of the conveying assembly 11 and can demould two molds 100 at the same time. On the machine table 4, a loading station, a demoulding station and a unloading station are arranged in sequence along its length direction. Each demoulding assembly 21 includes a demoulding table 211 arranged on the machine table 4 and movable along the direction from the loading station to the unloading station, a first driving module 212 for driving the demoulding table 211 to move, two first top blocks 213 slidably arranged on the demoulding table 211, and two second driving modules 214 for driving the two first top blocks 213 to move. First rollers 215 are respectively arranged on both sides of the front end of each first top block 213. The mold 100 is carried on the demoulding table 211, and the sliding direction of the first top block 213 is the same as the arrangement direction of the two clamping plates 1003.

[0035] Among them, the first driving module 212 is a linear motor, and the second driving module 214 is a cylinder. The first driving module 212 drives the demolding platform 211 to gradually move to the demolding station. During the movement of the demolding platform 211, the two second driving modules 214 drive the two first top blocks 213 to move in the opposite direction and push the two clamping plates 1003 open through the first roller 215. In this way, the clamping force between the male mold 1001 and the female mold 1002 is lost, and the grabbing mold assembly 22 can easily and quickly grab the male mold 1001, effectively improving the separation efficiency of the male mold 1001 and the female mold 1002.

[0036] In this embodiment, combined with Figure 2 As shown, the demoulding platform 211 includes a horizontally arranged platform 2111, two bearing columns 2112 respectively arranged on both sides of the platform 2111, the arrangement direction of the two bearing columns 2112 is perpendicular to the sliding direction of the first top block 213, the two first top blocks 213 are arranged side by side on the platform 2111 and located between the two bearing columns 2112, the arrangement direction of the two first top blocks 213 is the same as the arrangement direction of the two bearing columns 2112, and the height of the two first top blocks 213 is less than the height of the bearing columns 2112. In this way, the mold 100 can be suspended above the top block under the support of the two bearing columns 2112, so that the top block will not contact the mold 100 during the movement, preventing the mold 100 from interfering with the movement of the top block.

[0037] In this embodiment, combined with Figure 3 As shown, each gripper assembly 22 includes a gripper seat 221 that can be lifted and lowered and is disposed above the demoulding station, a third driving module 222 for driving the gripper seat 221 to lift and lower, two first clamping plates 223 that are respectively disposed on both sides of the gripper seat 221 and can be relatively close to or away from each other, and a fourth driving module 224 for driving the two first clamping plates 223 to move, and the moving direction of the two first clamping plates 223 is perpendicular to the sliding direction of the first top block 213. Among them, the third driving module 222 is a lifting cylinder, and the fourth driving module 224 is a clamping claw cylinder. The two first clamping plates 223 can cooperate with each other and quickly complete the grasping of the male mold 1001, which effectively improves the separation efficiency of the male mold 1001 and the female mold 1002.

[0038] In this embodiment, combined again Figure 3As shown, the demoulding mechanism 2 also includes a mold clamping assembly 23, which includes two second top blocks 231 that can be raised and lowered and are arranged on both sides of the mold gripping seat 221, and two fifth driving modules 232 that are respectively used to drive the two second top blocks 231 to rise and fall. The arrangement direction of the two second top blocks 231 is perpendicular to the arrangement direction of the two first clamping plates 223, and the bottom sides of each second top block 231 are respectively provided with second rollers 233. Among them, the fifth driving module 232 is a cylinder, and the two second top blocks 231 can respectively press the two clamping plates 1003 through the second rollers 233 during their respective lifting processes, so as to drive the clamping plates 1003 to flip and realize the relative assembly of the male mold 1001 and the female mold 1002 after the screen is unloaded, so as to prevent the male mold 1001 and the female mold 1002 from being relatively separated during output and affecting the subsequent use of the mold 100; at the same time, there is no need to manually assemble the mold 100, which improves the output efficiency of the mold 100.

[0039] When the male mold 1001 and the female mold 1002 are relatively buckled by the clamping plate 1003, since one side of the clamping plate 1003 protrudes from the female mold 1002, the male mold 1001 needs to be located below the female mold 1002 and carried on the belt conveyor during transportation of the mold 100, so as to prevent the clamping plate 1003 from interfering with the belt conveyor 111; and when demolding, the male mold 1001 needs to be located above the female mold 1001, so as to facilitate the grabbing mold assembly 22 to grab and lift the male mold 1001. In this way, in order to simultaneously meet the transportation requirements and the grabbing mold requirements of the mold 100, the male mold 1001 is combined with the female mold 1001 to form a mold assembly 22. Figure 1 As shown, the upper and lower mold mechanisms 1 of the present embodiment further include two flip mold assemblies 12 disposed between the conveying assembly 11 and the demolding mechanism 2, the two flip mold assemblies 12 include a first flip mold assembly and a second flip mold assembly, the first flip mold assembly and the second flip mold assembly are respectively used for flipping and transferring the mold 100 between the two belt conveyors 111 and the demolding table 211, the first flip mold assembly is located at the loading station, and is used for transferring and flipping the fully loaded mold 100 between the first belt conveyor and the demolding table 211, the second flip mold assembly is located at the demolding station, and is used for transferring and flipping the unloaded mold 100 between the demolding table 211 and the second belt conveyor, and two clamping assemblies 23 are arranged on the flip mold frame 121 constituting the second flip mold assembly.

[0040] In this embodiment, if Figure 1 and Figure 4As shown, each mold-turning assembly 12 includes a mold-turning frame 121, a mold-turning base 122 which can be raised and lowered and moved along the width direction of the machine table 4 and is arranged on the mold-turning frame 121, a sixth driving module 123 for driving the mold-turning base 122 to move, two second clamping plates 124 which are respectively arranged on both sides of the mold-turning base 122 and can be relatively close to or away from each other, a seventh driving module 125 for driving one of the second clamping plates 124 to move, two mold-turning templates 126 which are respectively rotatable around the horizontal direction and are arranged at the lower part of the side where the two second clamping plates 124 are close to each other, and an eighth driving module 127 for driving one of the mold-turning templates 126 to rotate.

[0041] Among them, the sixth driving module 123 is a lifting cylinder, the seventh driving module 125 is a translation cylinder, the eighth driving module 127 is a motor gear structure, and the flipping plate 126 is connected to the second clamping plate 124 through a rotating shaft, and a gear is arranged on the rotating shaft, and the motor cooperates with the gear transmission. When the fully loaded mold 100 is transported from the first belt conveyor, the mold 100 remains in a state where the male mold 1001 is at the bottom and the female mold 1002 is at the top. Then the first flipping mold assembly transfers the mold 100 from the first belt conveyor to the demolding platform 211. During the transfer process, the two second clamping plates 124 and the two flipping molds 126 cooperate with each other and flip the mold 100 to a state where the female mold 1002 is at the bottom and the male mold 1001 is at the top. At this time, the grabbing mold assembly 22 can easily grab and lift the male mold 1001; after the screen is unloaded, the grabbing mold assembly 2 2 and the clamping assembly 23 assemble the male mold 1001 and the female mold 1002 into an unloaded mold 100. At this time, the mold 100 is in a state where the female mold 1002 is at the bottom and the male mold 1001 is at the top. Then the second flipping mold assembly 12 transfers the mold 100 from the demolding table 211 to the second belt conveyor. During the transfer process, the two second clamping plates 124 and the two flipping mold plates 126 cooperate with each other and flip the mold 100 to a state where the male mold 1001 is at the bottom and the female mold 1002 is at the top. At this time, the mold 100 can be stably carried on the second belt conveyor.

Among them, the ninth driving module 313 is a cylinder. The unloading seat 312 can suck the screen through the first suction cup 314 during its movement and complete the unloading of the screen, which effectively improves the unloading efficiency of the screen.

[0043] like Figure 1 and Figure 6As shown, the material unloading mechanism 3 also includes a flipping assembly 32, the translation direction of the material unloading seat 312 is the same as the direction from the material unloading assembly 31 to the flipping assembly 32, and the flipping assembly 32 includes a flipping frame 321, a flipping plate 322 which can be lifted and rotated around the horizontal direction and is arranged on the flipping frame 321, a tenth driving module 323 for driving the flipping plate 322 to move, and a plurality of second suction cups 324 arranged on the flipping plate 322. Among them, the tenth driving module 323 is a motor, and the flipping plate 322 can bear the screen and complete the flipping and unloading of the screen to prevent the screen from being damaged due to accidental falling during the movement of the material unloading seat 312.

[0044] Specifically, when unloading, the unloading seat 312 moves to the top of the unloading station and sucks the screen from the demolding table 211, and then the unloading seat 312 moves to the flipping assembly 32 and places the screen on the flipping plate 322. The flipping plate 322 absorbs the screen and flips it over and places it on the conveyor belt, thereby completing the output of the screen.

[0045] In this embodiment, combined again Figure 1 As shown, temporary storage mechanisms 5 are respectively provided on the side of the two mold turning assemblies 12 away from the upper and lower mold mechanisms 1.
