Description

Technical Field

[0001] This invention relates to the field of mold manufacturing and processing technology, and specifically to a multi-positioning device for pressing glass panels. Background Technology

[0002] In the glass panel lamination, bonding, and flattening pressing process, it is often necessary to stack two layers of glass and then press them together as a whole for shaping. The pressing and positioning accuracy directly determines the finished product qualification rate and appearance quality. At present, the traditional glass pressing device has a relatively simple structure, mostly relying on a single bottom limiting groove to achieve glass placement and positioning, and the pressing plate mostly adopts an integral elastic plate structure. Because it only relies on a single bottom limiting groove, the pressing plate is prone to horizontal slight displacement and swaying during the pressing process, which in turn causes the upper glass to be misaligned and shifted, resulting in uneven overlapping edges, large alignment deviations, and a high scrap rate. When the pressing plate of purely elastic material is subjected to large-area pressure, it is very easy to have deformation problems such as central depression and edge suspension. Uneven pressure distribution on the plate surface leads to local stress concentration in the glass, which easily produces defects such as edge chipping, cracking, and incomplete pressing. Summary of the Invention

[0003] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a multi-positioning device for glass panel pressing, which solves the problems of large alignment deviation and glass misalignment in traditional pressing devices, and effectively improves the precision of glass pressing processing.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a multi-positioning device for glass panel pressing, including a worktable and a support frame disposed on the worktable, and further including: a receiving seat, which is adapted to the glass to be pressed; a support connecting assembly, wherein multiple support connecting assemblies are disposed at the bottom of the receiving seat, and each support connecting assembly is detachably disposed on the worktable; a lifting mechanism, which is disposed on the support frame; an elastic pressing plate, which is connected to the lifting mechanism and is used to press the glass to be pressed; and reinforcing rods, wherein multiple reinforcing rods are evenly distributed on the elastic pressing plate and the reinforcing rods penetrate the elastic pressing plate.

[0005] Furthermore, it also includes alignment blocks, with elastic pressing plates extending from both ends of each reinforcing rod and fixedly connected to alignment blocks respectively, and all alignment blocks can be fitted onto the receiving seat.

[0006] Furthermore, the receiving seat includes a support mold base, on which a limiting groove adapted to the glass to be pressed is provided; wherein, the support connecting assembly is provided at the bottom of the support mold base.

[0007] Furthermore, the receiving seat also includes multiple alignment sleeves, which are arranged in a one-to-one correspondence with the alignment blocks, and the alignment blocks are adapted to the alignment sleeves.

[0008] Furthermore, a chamfered transition is provided at the connection between the inner wall of the alignment sleeve and its top surface.

[0009] Furthermore, the support connection assembly includes: a limiting sleeve, which is disposed on the worktable; a connector, which is fitted inside the limiting sleeve and connected to the bottom of the support mold base; wherein the connector is detachably connected to the worktable by fasteners.

[0010] Furthermore, the connecting component includes: a connecting post, which is fixedly connected to the support mold base; and a limiting post, which is fixedly connected to the connecting post and fits inside the limiting sleeve.

[0011] Furthermore, the lifting mechanism includes: a connecting plate, which is fixedly connected to an elastic pressing plate; a connector, which is fixedly connected to the connecting plate; and a driving component, which is mounted on a support frame and connected to the connector; wherein the driving component drives the connector to lift.

[0012] Furthermore, the driving component is a hydraulic cylinder, and the connector is fixedly sleeved on the outside of the hydraulic cylinder piston rod.

[0013] Furthermore, the outer diameter of the connector increases from top to bottom.

[0014] The beneficial effects of this invention are as follows.

[0015] 1. This invention features a limiting groove and a multi-positioning structure formed by the cooperation of the alignment block and the alignment sleeve. A limiting groove is provided at the upper end of the support mold base to achieve pre-limiting of the bottom of the glass. A reinforcing rod is arranged through the elastic pressing plate, and the end of the reinforcing rod is fixed to the alignment block. During the pressing process, the alignment block cooperates with the alignment sleeve to complete the guiding insertion and limit the horizontal displacement of the elastic pressing plate. This invention solves the problems of large alignment deviation and glass misalignment in traditional pressing devices and effectively improves the glass pressing processing accuracy.

[0016] 2. In this invention, multiple reinforcing rods are evenly arranged inside the elastic pressing plate, and pressure is transmitted in conjunction with a variable diameter connector. The reinforcing rods can constrain the deformation of the elastic pressing plate under pressure and prevent the center of the plate from concave and bending. The connector with an increasing outer diameter from top to bottom increases the force transmission area, avoids stress concentration, and makes the pressure evenly distributed on the glass plate surface.

[0017] 3. By setting multiple sets of detachable support connection components, which are composed of limit sleeves and connectors that fit together; the matrix arrangement of multiple sets of support connection components evenly distributes the bearing pressure and improves the pressure bearing stability of the mold base.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1 Please see Figures 1-6This embodiment provides a multi-positioning device for glass panel pressing, including a worktable 1. The worktable 1 is the supporting base of the whole equipment. The surface of the worktable 1 is flattened to ensure that the table surface is flat and without skewing. A support frame 2 is fixedly installed on the top of the worktable 1. The support frame 2 is welded from a hard metal profile and is used to support the lifting mechanism 5 to ensure that the lifting mechanism 5 will not shake or deviate when it is working.

[0029] It also includes a receiving seat 3, which is adapted to the glass to be pressed; the glass to be pressed is placed smoothly inside the receiving seat 3, and the receiving seat 3 supports and limits the glass to prevent the glass from slipping before pressing.

[0030] Furthermore, the bottom of the receiving seat 3 is provided with multiple sets of support connection components 4. The support connection components 4 are used to detachably fix the receiving seat 3 to the upper end of the workbench 1, which is convenient for workers to quickly disassemble and assemble. The support frame 2 is equipped with a lifting mechanism 5. The lifting mechanism 5 is arranged vertically, and the lower end of the lifting mechanism 5 is connected to the elastic pressing plate 6. The glass pressing operation is completed by lowering the elastic pressing plate 6.

[0031] Multiple reinforcing rods 7 are evenly distributed throughout the elastic pressing plate 6. The reinforcing rods 7 are spaced apart and are used to improve the structural strength of the elastic pressing plate 6 and reduce the deformation under pressure.

[0032] Specifically, the receiving seat 3 includes a support mold base 31, which is made of metal and has high structural rigidity, making it less prone to deformation. A limiting groove 32 is provided at the upper end of the support mold base 31. The contour of the limiting groove 32 is adapted to the shape of the glass to be pressed, and the glass can be directly placed inside the limiting groove 32 to achieve positioning and prevent the glass from shifting to the left or right. The receiving seat 3 is not a simple flat plate structure. The depth of the limiting groove 32 is 1.3-1.5 times the thickness of a single layer of glass, so that the two pieces of glass to be pressed can fit together naturally after being placed in, and achieve constraint on the four degrees of freedom of the glass in the horizontal direction.

[0033] The bottom of the support mold base 31 has four support connection components 4 arranged in a rectangular array. The multiple sets of support connection components 4 evenly distribute the weight of the support mold base 31 and the glass, and are used to support and fix the support mold base 31 to ensure that the support mold base 31 is placed stably.

[0034] The support connection assembly 4 includes a limiting sleeve 41 and a connector 42. The limiting sleeve 41 is fixed to the upper surface of the worktable 1, and its position is fixed and does not shift. The connector 42 can be installed inside the limiting sleeve 41 to achieve insertion and positioning. The connector 42 includes a connecting post 421 and a limiting post 422. The upper end of the connecting post 421 is fixedly connected to the support mold base 31, and the limiting post 422 is fixed to the lower end of the connecting post 421. The limiting post 422 is engaged and locked inside the limiting sleeve 41 to limit horizontal sway. The connector 42 is detachably fixed to the worktable 1 by fasteners, which are simple to assemble and disassemble and are securely locked. Specifically, the limiting post 422 is connected by screws or bolts through the worktable 1 and is threadedly connected to the screws or bolts. Of course, the limiting post 422 is provided with threaded holes that are compatible with the screws or bolts.

[0035] The lifting mechanism 5 includes a connecting plate 51, a connector 52, and a driving component 53. The driving component 53 is a hydraulic cylinder, which is fixedly installed on the support frame 2 and has a stable and controllable output pressure. The connector 52 is fixedly sleeved on the outside of the piston rod of the hydraulic cylinder. The outer diameter of the connector 52 increases from top to bottom to improve the force transmission effect and avoid stress concentration. The lower end of the connector 52 is fixedly connected to the connecting plate 51, and the connecting plate 51 is fixedly connected to the upper end face of the elastic pressing plate 6 to ensure a tight connection.

[0036] The elastic pressing plate 6 is made of elastic rubber composite material. The plate surface is soft and has the ability to buffer and resist pressure. It can fit the curved surface of the glass and avoid damage to the glass by hard compression. Multiple reinforcing rods 7 are vertically inserted inside the elastic pressing plate 6. The reinforcing rods 7 are evenly distributed and the force is evenly distributed. The reinforcing rods 7 are made of hard metal material and have high rigidity. They are used to prevent the elastic pressing plate 6 from deforming and bending under pressure and to maintain the flatness of the plate surface.

[0037] In this embodiment, the glass to be processed is placed inside the limiting groove 32 of the support mold base 31, and positioned against the groove wall to complete the positioning. The support mold base 31 is fixed on the worktable 1 by multiple sets of support connecting components 4 at the bottom, which is convenient to disassemble and assemble and provides stable positioning, making it less prone to displacement deviation. The hydraulic cylinder is activated, and the piston rod slowly and uniformly extends and retracts, driving the connector 52 and the connecting plate 51 to move downward, pushing the elastic pressing plate 6 vertically downward, so that the elastic pressing plate 6 smoothly adheres to the glass surface to complete the pressing operation. The reinforcing rod 7 can improve the overall rigidity of the elastic pressing plate 6, prevent the plate surface from denting during the pressing process, ensure uniform pressure on the glass, effectively improve the glass pressing quality, reduce the probability of glass breakage, and is suitable for simple pressing processing of conventional flat glass.

[0038] Example 2 like Figures 1 to 6As shown, this embodiment discloses another multi-positioning device for glass panel pressing. The basic structure of this embodiment is consistent with that of Embodiment 1, including a worktable 1, a support frame 2, a receiving seat 3, a support connecting assembly 4, a lifting mechanism 5, and an elastic pressing plate 6. The worktable 1 is used for overall structural support and bears the weight of all components. The support frame 2 is used to fix the lifting mechanism 5 and ensure the verticality of the lifting operation. The receiving seat 3 is used to place the glass to be pressed and support the glass. The support connecting assembly 4 is used to detachably fix the receiving seat 3 for easy mold replacement. The lifting mechanism 5 drives the elastic pressing plate 6 to move up and down to complete the pressing operation, and the downward pressing stroke is controllable.

[0039] Specifically, the receiving seat 3 includes a support mold base 31. The upper end of the support mold base 31 has a limiting groove 32 for placing glass. The inner wall of the limiting groove 32 is smooth and will not scratch the edges of the glass. Multiple alignment sleeves 33 are also fixedly installed on the upper end of the support mold base 31. The alignment sleeves 33 are arranged at intervals on the outside of the limiting groove 32 and do not occupy the glass placement area. A chamfer transition 331 is provided at the connection between the inner wall of the alignment sleeve 33 and the top surface. The chamfer transition 331 can play a guiding role and reduce the difficulty of alignment.

[0040] The supporting connection assembly 4 includes a limiting sleeve 41 and a connector 42. The limiting sleeve 41 is fixed on the worktable 1, and the installation position is precise. The connector 42 consists of a connecting post 421 and a limiting post 422. The limiting post 422 is fitted inside the limiting sleeve 41 to achieve insertion and limiting. The connector 42 is locked and fixed by fasteners, which makes disassembly and assembly convenient, and there is no looseness after locking.

[0041] The lifting mechanism 5 includes a connecting plate 51, a connector 52, and a driving component 53. The driving component 53 is a hydraulic cylinder, which runs smoothly without impact. The outer diameter of the connector 52 gradually increases from top to bottom, which improves its structural strength and makes it less prone to breakage and deformation. The lower end of the connector 52 is fixedly connected to the connecting plate 51, and the connecting plate 51 is attached and fixed to the upper end of the elastic pressing plate 6, which increases the force transmission area.

[0042] Multiple reinforcing rods 7 are installed through the elastic pressing plate 6, with both ends of the reinforcing rods 7 extending out of the surface of the elastic pressing plate 6, leaving space for alignment and installation.

[0043] Alignment blocks 71 are fixedly connected to both ends of the reinforcing rod 7. The alignment blocks 71 are firmly fixed to the reinforcing rod 7 without loosening or shaking. The alignment blocks 71 and the alignment sleeves 33 are arranged in a one-to-one correspondence, and the outer dimensions of the alignment blocks 71 are adapted to the inner diameter of the alignment sleeves 33, with a small insertion gap and high positioning accuracy.

[0044] In this embodiment, the basic positioning structure of Embodiment 1 is retained, and the bottom of the glass is limited by the limiting groove 32 to prevent the glass from shifting. During the downward movement of the elastic pressing plate 6, the alignment block 71 at the end of the reinforcing rod 7 first contacts the alignment sleeve 33. The chamfer at the upper end of the alignment sleeve 33 is used for guidance and correction. Even if there is a slight deviation, it can be automatically corrected, so that the alignment block 71 is accurately inserted into the alignment sleeve 33. Through the cooperation between the alignment block 71 and the alignment sleeve 33, the horizontal displacement of the elastic pressing plate 6 is limited, and secondary precise positioning is achieved. This embodiment adds an upper and lower alignment structure and multiple limiting cooperation to effectively prevent displacement and misalignment during the glass pressing process, further improving the glass pressing accuracy. It is suitable for small glass pressing operations with high precision requirements.

[0045] Example 3 like Figures 1 to 6 As shown, this embodiment is based on embodiment two. This embodiment optimizes the assembly method of the support connection component 4, changes the arrangement density, improves the overall load-bearing stability of the device, adapts to large-size and heavy glass pressing operations, and broadens the application range of the device.

[0046] Specifically, the number of support connection components 4 is increased, and multiple sets of support connection components 4 are arranged in a matrix at the bottom of the support mold base 31, resulting in more stress points and more uniform load bearing; the limit post 422 is lengthened to increase the fitting depth between the limit post 422 and the limit sleeve 41, reduce the swaying gap, and improve the load bearing stability of the support mold base 31.

[0047] The elastic pressing plate 6 is thickened, improving its overall compressive strength; the reinforcing rod 7 is thickened, increasing its hardness and enhancing its bending resistance, thus preventing the elastic pressing plate 6 from bending and deforming in the middle when pressing large-sized glass; the alignment block 71 is made of hard alloy material, which has excellent wear resistance, is not easily worn or deformed, and is suitable for long-term mass production operations.

[0048] The drive component 53 in the lifting mechanism 5 is a high-thrust hydraulic cylinder to meet the pressing force required for thick glass; the connector 52 is integrally forged, with higher structural strength, able to withstand greater downward load, and less prone to breakage.

[0049] In this embodiment, multiple sets of support connection components 4 at the bottom of the support mold base 31 share the load-bearing pressure, preventing the support mold base 31 from shaking or shifting under heavy load, and greatly improving the stability of the base; the alignment block 71 and the alignment sleeve 33 still maintain the precise alignment function, and together with the limiting groove 32, they form a multi-positioning structure with excellent positioning effect.

[0050] The thickened and reinforced rod 7 effectively resists the deformation of the sheet metal, and the high-thrust hydraulic cylinder meets the requirements for pressing heavy glass. This embodiment improves the structural load-bearing capacity and versatility while retaining the original simple structure (i.e. the structure in embodiment two). It can process conventional small glass as well as large-size heavy glass. It is precise in positioning, easy to disassemble and assemble, and has a wider range of applications, making it more suitable for industrial mass production.

[0051] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
