Description

Technical Field

[0001] This application discloses the field of 3D curved cover glass production technology, and in particular, a mold lifting device. Background Technology

[0002] In today's rapidly evolving technological era, the surge in demand for large-screen displays in automobiles, computers, and other consumer electronics has driven unprecedented demand for high-quality cover glass. This cover glass not only requires high strength, high transparency, and scratch resistance, but also must adapt to various complex curved designs to meet modern aesthetic and technical standards. Therefore, 3D curved cover glass, as a key component, not only protects the display screen but also serves as an important vehicle for design innovation.

[0003] However, as product dimensions increase, the corresponding cover glass dimensions also increase, placing higher demands on the molds used in production. Each specific size and shape of 3D curved cover glass requires a customized mold for precise forming, resulting in a wide variety of mold types with varying sizes and weights. Traditional manual mold lifting methods are inadequate when dealing with increasingly larger and heavier molds. The need for two or more people to lift and transport molds is not only inefficient and increases labor costs, but also poses safety hazards. Workers are prone to injury due to prolonged heavy lifting or improper operation. While robotic arms are used to lift and move molds, the clamping force applied to the mold is difficult to control. Excessive clamping force can cause mold deformation, affecting the forming effect of the curved glass; insufficient clamping force, due to the mold's own weight, can cause it to fall from the clamp during lifting and movement, resulting in economic losses.

[0004] Therefore, the safe and stable lifting and handling of large-sized molds has become a technical problem that urgently needs to be solved. Utility Model Content

[0038] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0039] As the product size of 3D curved cover glass increases, the size of the molds used to produce curved cover glass also increases. Traditional manual mold lifting is not only inefficient and increases labor costs, but also easily causes the mold to fall and be damaged. Using mechanical clamping arms to hold the mold makes it difficult to control the clamping force applied to the mold. Excessive clamping force will cause the mold to deform, thus affecting the forming effect of the curved glass in the mold. If the clamping force is too small, the mold itself has a certain weight, and it is easy to fall and be damaged during the lifting and moving of the mold, resulting in economic losses.

[0040] To solve the above problems, this application proposes a mold lifting device, which uses the second drive part of the support mechanism to drive two support components to move closer or further apart, so that the U-shaped frame structure formed by the support components is fitted onto both ends of the mold. After the support component is installed in accordance with the mounting part set at the lower end of the mold, the mold is lifted under the driving action of the first drive part of the lifting mechanism.

[0041] like Figure 1-3 As shown, a mold lifting device includes: a frame 1, a lifting mechanism 2, and a supporting mechanism 3;

[0042] The lifting mechanism 2 is installed on the frame 1. The lifting mechanism 2 includes a first drive unit 210. The supporting mechanism 3 is connected to the drive end of the first drive unit 210. The first drive unit 210 drives the supporting mechanism 3 to reciprocate along a first direction.

[0043] The support mechanism 3 includes a second drive unit 310 and at least two support components 320, the at least two support components 320 are spaced apart, and the second drive unit 310 drives the two support components 320 to move closer or further apart from each other along a second direction.

[0044] The supporting component 320 includes a mounting component 321, a connector 322, and a supporting component 323. The first end of the connector 322 is fixedly disposed with the mounting component 321, and the second end of the connector 322 extends away from the first end along a first direction. The supporting component 323 is disposed along a third direction and its two ends are respectively connected to the second ends of the connector 322, which are spaced apart, thereby forming a U-shaped frame structure. The U-shaped frame structure is used to support the mold.

[0045] The first direction is the vertical direction, the second direction is the first horizontal direction, and the third direction is the second horizontal direction, with the first horizontal direction being perpendicular to the second horizontal direction.

[0046] Specifically, the frame 1 serves to support the overall structure, and the lifting mechanism 2 sits on it. The frame 1 can be made of welded metal frame and set on the ground or mold transport operating platform. The frame 1 can also be composed of multiple metal beams, which are connected to the steel structure of the factory building, so that the whole device is suspended in the air and does not occupy ground space.

[0047] The first drive unit 210 is a servo motor or a drive cylinder. When the first drive unit 210 is a servo motor, the output end of the servo motor is connected to a threaded screw, which is set along the first direction, i.e., the vertical direction. At this time, the support mechanism 3 is assembled on the threaded screw through the integrally set internal thread structure mounting part 321 or the internal thread structure mounting hole formed by the support mechanism 3 itself. Following the clockwise and counterclockwise rotation of the servo motor, the support mechanism 3 moves back and forth along the length direction of the threaded screw, converting the circular motion of the output end of the servo motor into linear motion, thereby raising and lowering the mold assembled on the support mechanism 3.

[0048] When the first drive unit 210 is a drive cylinder, the drive cylinder includes an electric servo cylinder, a pneumatic cylinder, and a hydraulic cylinder. The drive cylinder is vertically arranged along the first direction. At this time, the output end of the drive cylinder can realize reciprocating motion along the first direction. The support mechanism 3 is fixedly connected to the output end of the drive cylinder, thereby realizing the lifting and lowering motion of the mold assembled on the support mechanism 3.

[0049] The second drive unit 310 of the support mechanism 3 can be a servo motor or a drive cylinder. When the second drive unit 310 is a servo motor, the servo motor and the bidirectional threaded screw can cooperate to make the two support components 320 move closer or further apart. The output end of the servo motor is connected to the input end of the bidirectional threaded screw through a toothed chain or belt. The input end is a gear or grooved wheel fixedly set in the middle section of the bidirectional threaded screw.

[0050] The rotation of the bidirectional threaded screw can be achieved by either meshing the gear with the toothed chain or by embedding a rubber belt into a grooved wheel. The two ends of the bidirectional threaded screw are provided with opposite external thread structures. When the bidirectional threaded screw is driven to rotate by a servo motor, the support components 320, which are respectively assembled at both ends of the bidirectional threaded screw using thread structures, can move closer or further apart.

[0051] When the second drive unit 310 is a drive cylinder, the drive cylinder includes an electric servo cylinder, a pneumatic cylinder or a hydraulic cylinder; there are at least two drive cylinders, which are arranged at intervals relative to each other along the second direction, and the two support components 320 are respectively connected to the output end of the drive cylinder. The output end of the drive cylinder reciprocates along the second direction, thereby driving the two support components 320 to move closer or further away from each other.

[0052] To stabilize the lifting of the mold, an installation part is provided at the lower end of the mold. The installation part is located at both ends in the length direction of the mold and is a groove extending in the third direction, so that the support member 323 can be embedded in the groove so that the mold remains stable with the support mechanism 3 during the lifting process.

[0053] The U-shaped frame structure formed by the support component 320 can be a straight part or a curved part. The curved part can be adapted to the lower mounting part of a specific type of mold, so that the mold assembled on the support component 320 is more secure and stable during the lifting process. The curved part cooperates with the specific mold to play a limiting role.

[0054] The support member 323 can be a rigid rod or plate of a certain length, or it can be a flexible strip or rope structure. Both ends of the support member 323 are respectively connected to the second ends of the connectors 322 that are spaced apart along a third direction.

[0055] The connector 322 has a certain length so that the U-shaped frame structure has enough space to accommodate the mold and will not be unable to assemble due to the excessive thickness of the mold.

[0056] The connector 322 can be detachably mounted on the mounting part 321. The mounting part 321 is provided with a mounting hole. The connector 322 passes through the mounting hole from one side of the mounting part 321 and exits from the other side of the mounting part 321. It is fixed by a nut using a threaded structure so that different lengths of connector 322 can be flexibly replaced according to the thickness of the mold, thus adapting to the mold support needs of different thicknesses.

[0057] The mold lifting device disclosed in this application has a supporting mechanism 3 connected to the output end of the first drive mechanism of the lifting mechanism 2, and reciprocating vertically under the drive of the first drive unit 210. At least two supporting components 320 are provided on the supporting mechanism 3. Under the drive of the second drive unit 310, the supporting components 320 move closer or further apart. The supporting components 320 form a U-shaped frame structure with the supporting member 323 via a connecting member 322. The U-shaped frame structure can accommodate both ends of the mold to be lifted. Under the combined drive of the lifting mechanism 2 and the supporting mechanism 3, the supporting member 323 of the supporting component 320 first descends below the mold. Then, the two supporting components 320 move closer together, placing both ends of the mold within the U-shaped frame structure. Finally, the supporting mechanism 3 is lifted as a whole, using the two supporting components 320 to lift the mold. This structure replaces the original method of mold clamping and handling, preventing the mold from deforming due to excessive clamping force or falling off and being damaged due to insufficient clamping force.

[0058] In some embodiments, the support component 320 further includes an elastic member 324 and a fixing member 325. One end of the elastic member 324 is fixedly connected to the mounting member 321, and the other end extends away from the mounting member 321. The fixing member 325 is disposed at the other end of the elastic member 324 and is spaced apart from the support member 323.

[0059] To further improve the stability of the mold placed in the U-shaped frame structure of the support component 320 during the lifting process, an elastic element 324 and a fixing element 325 are added. The elastic element 324 can be a spring, a rubber element, or a silicone element.

[0060] When the U-shaped frame structure of the supporting component 320 is fitted onto the mold, the elastic element 324 is compressed and deformed, causing the fixing element 325 to abut against the upper end face of the mold. This ensures that the mold assembly is firm, stable, and not easily detached.

[0061] In some embodiments, the fastener 325 includes a first end face 3251 and a second end face 3252. The first end faces 3251 of the two fasteners 325 are disposed opposite to each other, and the first end face 3251 is an arc surface. The second end face 3252 is disposed in the direction of the support member 323, and the second end face 3252 is a plane.

[0062] To facilitate the fitting of the U-shaped frame structure of the support component 320 onto one end of the mold, the first end face 3251 of the fixing member 325 is designed as an arc surface. This arc surface reduces the contact area between the fixing member 325 and the upper end of the mold, thus reducing frictional resistance. The second end face 3252 is designed as a plane, increasing the contact area with the mold and thus making the fixing member 325 more securely abutted. The second end face 3252 is a horizontal plane.

[0063] In some embodiments, the fixing member 325 is an electromagnet.

[0064] To further improve the stability of mold lifting, a metal part is provided on the upper surface of the mold. The metal part can be made of iron or steel. During assembly, the metal part is aligned with the position of the fixing part 325. During lifting and transportation, an electromagnet attracts the metal part. The electromagnet requires only a small amount of power to achieve the auxiliary fixing effect on the mold.

[0065] In some embodiments, the support member 323 is a roller, and both ends of the roller are rotatably connected to the second end of the connector 322.

[0066] Specifically, the roller can roll into contact with the lower end face of the mold, thereby reducing friction and facilitating the installation of the support assembly 320 and the mold.

[0067] In some embodiments, the lifting mechanism 2 further includes a lifting member 220, a first lead screw 230, and a first guide member 240;

[0068] The output end of the first drive unit 210 is connected to the first lead screw 230, and at least two first guide members 240 are respectively spaced apart on both sides of the first lead screw 230; the lifting member 220 is movably disposed on the first lead screw 230 so that the lifting member 220 can reciprocate along the length direction of the first lead screw 230, and the first guide member 240 passes through the lifting member 220.

[0069] The lifting component 220 is fixedly connected to the supporting mechanism 3, and the first lead screw 230 and the first guide component 240 are both arranged along the first direction.

[0070] Specifically, in order to improve the stability of the lifting mechanism 3, the first drive unit 210 of the lifting mechanism 2 adopts a servo motor and the first lead screw 230 adopts a ball screw, with a movable nut on the ball screw; the output end of the servo motor is connected to the ball screw for transmission, and when the output end drives the ball screw to rotate, the nut moves up and down along the length of the ball screw.

[0071] To improve the installation firmness of the support mechanism 3 and the lifting mechanism 2, as well as the stability during the lifting operation, a lifting component 220 is fixedly connected to the support mechanism 3. The lifting component 220 is a plate, and its specific shape can be a circular plate, a square plate, or a prismatic plate. A first through hole is opened in the middle of the lifting component 220, through which the lead screw is inserted. The lifting component 220 is connected to the nut on the ball screw, and is fixed by bolts passing through the flange of the nut. Specifically, nuts are provided on both the upper and lower end faces of the lifting component 220, and the lifting component 220 is fixed by clamping the lifting component 220 with two nuts. The diameter of the first through hole is larger than the diameter of the lead screw.

[0072] To improve stability and accuracy during the lifting process, two second through holes are spaced apart at the location of the first through hole, with each second through hole located on either side of the first through hole. The second through holes allow the first guide member 240 to pass through, and the second through holes are clearance-fitted with the first guide member 240 to allow the lifting member 220 to move along the length of the first guide member 240 during the lifting process, preventing the connecting plate from rotating or shifting, thereby improving the stability and accuracy of the lifting process.

[0073] In some embodiments, the lifting mechanism 2 further includes a housing 250; a first drive unit 210 is disposed on the outside of the housing 250, a first lead screw 230 and a first guide member 240 are both disposed in the housing 250, and the output end of the first drive unit 210 passes through the housing 250 and is connected to the first lead screw 230 for transmission, and the two ends of the first guide member 240 are respectively disposed on two end faces of the housing 250 that are disposed opposite to each other along the first direction;

[0074] A hollow section 251 is provided on the outer peripheral side wall of the housing 250 along the first direction, and the supporting mechanism 3 is fixedly connected to the lifting component 220 inside the housing 250 through the hollow section 251.

[0075] Specifically, the housing 250 is located at the upper end of the frame 1 and has an internal space for housing the first lead screw 230 and the first guide member 240. The housing 250 protects the first lead screw 230 and the first guide member 240, preventing the first guide member 240 from directly contacting the outside and corroding, which would affect the smooth lifting of the lifting member 220. At the same time, the housing 250 also serves as a mounting support. The first drive mechanism uses a servo motor, which is fixedly installed on the outside of the housing 250, and the output end of the servo motor extends into the housing 250 and connects to the first lead screw 230.

[0076] In some embodiments, the lifting mechanism 2 further includes a lifting frame 260, the first end of which is connected to the lifting member 220 through a hollow portion 251; the second end of the lifting frame 260 extends in a first direction away from the first end and is connected to the supporting mechanism 3.

[0077] Specifically, the lifting frame 260 is a truss-type support with a crossbeam and a column. The crossbeam is located at the upper end near the lifting mechanism 2 and is connected to the lifting component 220 through a perforated part 251. The connection method can be welding or bolting. One end of the column is connected to the crossbeam, and the other end extends away from the lifting mechanism 2 along a first direction and is connected to a supporting mechanism 3, ensuring that the total length of the column does not exceed the height of the frame 1. The lifting frame 260 is connected to the lifting component 220 and can move up and down along the first lead screw 230 with the lifting component 220, thereby driving the supporting mechanism 3 to move up and down relative to the lifting mechanism 2 at the lower end of the lifting mechanism 2. To prevent the lifting process of the supporting mechanism 3 from interfering with the frame 1 and the lifting mechanism 2 installed on the frame 1, the length of the column must not be shorter than the length of the first lead screw 230. This allows the lifting component 220 to rise to the top of the lead screw, with the supporting mechanism 3 close to the bottom of the lifting mechanism 2.

[0078] In order to achieve stable installation of the lifting frame 260 and the supporting mechanism 3, four support columns are set at the corners of the lifting frame 260 and are fixedly connected to the supporting mechanism 3 by welding.

[0079] In some embodiments, the support mechanism 3 further includes a mounting plate 330, a second drive unit 310, a bearing seat 350, and a double-threaded ball screw 360. The mounting plate 330 has two opposite end faces, one end face of which is connected to the second end of the lifting frame 260, and the other end face is provided with the bearing seat 350 and the second drive unit 310. The double-threaded ball screw 360 passes through the bearing seat 350 and is drivenly connected to the output end of the second drive unit 310. The support assembly 320 is threadedly connected to the double-threaded ball screw.

[0080] Specifically, the mounting plate 330 is a plate with a certain thickness and structural strength, serving as a connector and fixation element. The side end of the mounting plate 330 opposite to the lifting frame 260 is fixedly connected to the support column of the lifting frame 260. The second drive unit 310 and the bearing seat 350 are provided at the middle section of the side end of the mounting plate 330 opposite to the lifting frame 260.

[0081] The second drive unit 310 uses a servo motor and is placed horizontally along the second direction. The output end of the second drive unit 310 is a drive wheel, and a driven wheel is fixedly installed in the middle section of the double thread ball screw 360. The drive wheel and the driven wheel are connected by a belt.

[0082] The double-threaded ball screw 360 has two oppositely arranged threaded sections at its two ends, which are respectively located at the two ends of the driven wheel. Each threaded section has a nut that moves along the length of the screw using the thread. By rotating the output end of the second drive unit 310, the double-threaded ball screw 360 is driven to rotate synchronously, thereby causing the support components 320 to move closer or further apart.

[0083] A flange end plate is provided on the side of the nut near the support assembly 320. The flange end plate is connected to the mounting part 321 of the support assembly 320 to form an integral part.

[0084] In some embodiments, a guide limiting groove 340 is provided on the other end face of the mounting plate 330 along the second direction;

[0085] The support component 320 is assembled in the guide limiting groove 340 and moves along the length of the guide limiting groove 340.

[0086] Specifically, in order to enable the support component 320 to move stably relative to the mounting plate 330, a locking block is provided at one end of the support component 320, which is then assembled into the guide limiting groove 340.
