Description

[Technical Field]

[0002] This utility model relates to the field of glass panel processing technology, and in particular to a clamping and positioning device for irregularly shaped panels. [Background Technology]

[0004] With the rapid development of the small home appliance market, consumers are increasingly demanding higher standards for product design and personalization. As a crucial component of many small appliances (such as microwave ovens, induction cookers, and coffee makers), glass panels are gradually shifting from traditional rectangular shapes to irregularly shaped designs to meet diverse and personalized market needs. Irregularly shaped glass panels not only enhance the aesthetics and technological feel of the products but also provide more possibilities for product functional innovation. However, the manufacturing process of irregularly shaped glass panels, especially the printing process, faces numerous technical challenges.

[0005] Clamping and positioning are crucial steps in the printing process of glass panels. Traditional clamping tools are typically designed for rectangular panels with regular shapes, making it difficult to adapt to the complex edge contours of irregularly shaped glass panels. Due to the irregular shape of irregularly shaped glass panels, their edges may contain arcs or curves, and traditional single-sided clamping or simple four-sided fixing methods often cannot provide uniform and stable clamping force. This causes the glass panel to wobble or shift during the printing process, affecting the accuracy and consistency of the printed pattern, and even increasing the defect rate and reducing production efficiency. [Utility Model Content]

[0007] The purpose of this utility model is to provide a clamping and positioning device for irregularly shaped panels, which aims to solve the problems of low printing accuracy and high defect rate caused by unstable clamping and poor adaptability of irregularly shaped glass panels in the printing process in the prior art.

[0008] This utility model is achieved through the following technical solution:

[0009] A clamping and positioning device for irregularly shaped panels includes a first clamping block for supporting and fixing one side of the panel body, and a second clamping block for supporting and fixing the other side of the panel body. The first clamping block and the second clamping block are identical and symmetrically arranged to form a clamping space. The first clamping block has a first positioning groove in the middle, and the second clamping block has a second positioning groove in the middle.

[0010] As described above, in a non-circular panel clamping and positioning device, the first positioning groove gradually converges from both ends toward the center in an arc shape.

[0011] As described above, an irregular panel clamping and positioning device includes an arc segment L1 located on both sides in the first positioning groove, and a straight segment L2 connecting the two arc segments L1.

[0012] As described above, in a non-circular panel clamping and positioning device, the length of the first clamping block is L3, and 1 / 3≤L3 / L1×2+L2≤1 / 2.

[0013] As described above, in a non-circular panel clamping and positioning device, the first positioning groove has a first rounded corner at both ends of its edge, and the first clamping block has a second rounded corner at both ends.

[0014] As described above, in a non-circular panel clamping and positioning device, the first clamping block has a first mounting hole at both its upper and lower parts, which is arranged along its width direction.

[0015] As described above, an irregular panel clamping and positioning device has a second mounting hole in the arc segment L1 of the first clamping block, which is provided along its width direction.

[0016] As described above, in a non-circular panel clamping and positioning device, both the first clamping block and the second clamping block are made of plastic material.

[0017] As described above, the thickness of the first clamping block and the second clamping block is 17~20mm.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] This invention, by setting a first positioning groove and a second positioning groove in the first clamping block and the second clamping block respectively, can better fit the irregular edge contour of the irregularly shaped glass panel. The symmetrical arrangement of the first and second clamping blocks applies clamping force evenly from both sides, avoiding the uneven force caused by traditional single-sided clamping or simple four-sided fixing methods. This effectively restricts the movement of the glass panel during the printing process, reduces pattern deviation caused by inaccurate positioning, and significantly improves printing accuracy.

Detailed Implementation Methods

[0026] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0027] With the continuous development of the small household appliance market, consumers have placed higher demands on the appearance and design of products. Among these, glass panels, as an important component of many small household appliances, are gradually shifting from traditional rectangular designs to irregular shapes to meet more diverse and personalized market needs. However, irregularly shaped glass panels face the challenge of achieving precise clamping and positioning during the printing process. Traditional clamping tools often cannot adapt to the shape of irregularly shaped glass panels, leading to wobbling or displacement during printing, affecting printing quality and efficiency. To achieve efficient and stable clamping of irregularly shaped glass panels, thereby improving printing accuracy and efficiency, this embodiment provides an irregularly shaped panel clamping and positioning device. Please refer to [link to relevant documentation]. Figures 1 to 3 It includes a first clamping block 2 for supporting and fixing one side of the panel body 1, and a second clamping block 3 for supporting and fixing the other side of the panel body 1. The first clamping block 2 and the second clamping block 3 are the same and symmetrically arranged to form a clamping space. The first clamping block 2 is provided with a first positioning groove 21 in the middle, and the second clamping block 3 is provided with a second positioning groove 31 in the middle.

[0028] In this embodiment, the clamping and positioning device includes a first clamping block 2 for supporting and fixing one side of the panel body 1, and a second clamping block 3 for supporting and fixing the other side of the glass panel body 1. The first clamping block 2 and the second clamping block 3 are identical and symmetrically arranged to form a clamping space. This symmetrical structure can better adapt to the shape of the irregular glass panel, apply clamping force evenly from both sides, and ensure that the glass panel remains stable during the printing process. The first clamping block 2 has a first positioning groove 21 in the middle, and the second clamping block 3 has a second positioning groove 31 in the middle. In actual operation, the irregularly shaped panel body 1 is placed in the clamping space formed by the first clamping block 2 and the second clamping block 3, so that both sides of the glass panel are tightly fitted with the first clamping block 2 and the second clamping block 3, respectively. Meanwhile, based on the irregular shape of the glass panel, specific parts on the panel, such as the edges, protrusions or recesses of the irregular shape, are aligned with the first positioning groove 21 and the second positioning groove 31 to achieve precise positioning. Compared with the traditional single-sided clamping or simple four-sided fixing method, it can provide a more uniform and stable clamping force, effectively preventing the glass panel from shifting or deforming due to the pressure or vibration of the printing equipment during the printing process, ensuring the smooth progress of the printing process, and improving the stability and reliability of production.

[0029] Furthermore, as a preferred embodiment of this solution and not a limitation, the first positioning groove 21 gradually converges from both ends toward the center in an arc shape.

[0030] In this embodiment, the first positioning groove 21 gradually converges from both ends towards the center in an arc shape. Correspondingly, the second positioning groove 31 also has an arc shape that is symmetrical to the first positioning groove 21 and gradually converges from both ends towards the center. In actual factory production, the irregularly shaped panel body 1 is placed in the clamping space formed by the first clamping block 2 and the second clamping block 3, so that both sides of the glass panel are tightly fitted to the first clamping block 2 and the second clamping block 3, respectively. For glass panels with arc or curved edge features, their edge portions can be better embedded into the arc-converging first positioning groove 21 and the second positioning groove 31. For example, if the edge of the glass panel is an outwardly protruding arc, then the arc edge can match the arc structure of the first positioning groove 21 and the second positioning groove 31, achieving a tighter fit and positioning.

[0031] The first positioning groove 21, with its arc-shaped structure gradually converging from both ends towards the center, can better conform to the edge contours of irregularly shaped small appliance glass panels, especially for panel bodies 1 with curved or rounded edges. This arc-shaped structure can more precisely restrict the movement of the glass panel during the printing process, reducing pattern deviations caused by inaccurate positioning, further improving printing accuracy, and ensuring high-quality product output. Furthermore, the arc-shaped positioning groove allows for more even force distribution on the glass panel during clamping, avoiding damage caused by excessive localized force. Simultaneously, due to the tight fit between the arc-shaped structure and the panel edge, the glass panel is less likely to slide or rotate within the positioning groove when subjected to pressure or vibration from the printing equipment, greatly enhancing clamping stability, ensuring smooth printing, and reducing the defect rate.

[0032] Furthermore, this arc-shaped, converging positioning groove structure is adaptable to irregularly shaped glass panels with varying curvatures. Whether the glass panel has a small or large edge curvature, the arc-shaped positioning groove enables effective positioning and clamping. This further enhances the versatility of the clamping and positioning device, allowing it to meet the printing needs of various irregularly shaped small household appliance glass panels, improving production efficiency, and reducing costs associated with replacing different clamping devices.

[0033] Furthermore, as a preferred embodiment of this solution and not a limitation, the first positioning groove 21 includes arc segments L1 located on both sides, and a straight segment L2 is connected between the two arc segments L1.

[0034] In this embodiment, the first positioning groove 21 in the middle of the first clamping block 2 of the clamping and positioning device includes arc segments L1 located on both sides, and a straight segment L2 connects the two arc segments L1. Correspondingly, the structure of the second positioning groove 31 in the middle of the second clamping block 3 is symmetrical with that of the first positioning groove 21, that is, the second positioning groove 31 also includes arc segments L1 located on both sides, and a straight segment L2 connects the two arc segments L1.

[0035] When using this irregularly shaped panel clamping and positioning device to clamp and position the panel body 1, for some irregularly shaped glass panel bodies 1 with both curved and relatively straight edges, the curved edges of the glass panel can closely fit the curved segments L1 on both sides of the first positioning groove 21 and the second positioning groove 31, while the relatively straight edges of the glass panel can be adapted to the straight segments L2 in the two positioning grooves. For example, when the two ends of the glass panel are curved and the middle part is a straight edge, when the glass panel is placed in the clamping space formed by the first clamping block 2 and the second clamping block 3, the curved edges at both ends of the glass panel can be embedded in the curved segments L1, while the straight edges in the middle fit with the straight segments L2, thereby achieving precise positioning. At the same time, the first clamping block 2 and the second clamping block 3 support and fix the glass panel body 1 from both sides, ensuring that the glass panel remains stable during the printing process. Compared to single curved or straight positioning grooves, this combined structure better conforms to the complex edge contours of the glass panel, further improving positioning accuracy and reducing displacement of the glass panel during printing due to poor edge fit. This enhances the accuracy of the printed pattern and product quality. Furthermore, the fit between the curved segment L1 and the straight segment L2 with the glass panel edge ensures more even force distribution during clamping. The curved segment L1 provides stable support for the curved edge of the glass panel, while the straight segment L2 provides additional support and fixation for the straight edge, preventing damage caused by uneven localized force. This further enhances the stability of the glass panel during printing and reduces the defect rate caused by glass panel movement or displacement.

[0036] Furthermore, as a preferred embodiment of this solution and not a limitation, the length of the first clamping block 2 is L3, and 1 / 3 ≤ L3 / L1×2+L2 ≤ 1 / 2.

[0037] In this embodiment, the dimensional relationship between the length L3 of the first clamping block 2 and the arc segment L1 and straight segment L2 in the first positioning groove 21 was further optimized. Specifically, by limiting the proportional relationship 1 / 3 ≤ L3 / L1 × 2 + L2 ≤ 1 / 2, the overall structure of the first clamping block 2 is made more compact and reasonable, while taking into account both clamping stability and space utilization of the device.

[0038] More specifically, the total length of the first clamping block 2 is L3, and the first positioning groove 21 is composed of the arc segments L1 on both sides and the straight segment L2 in the middle, with a total length of L1×2 + L2.

[0039] The ratio 1 / 3 ≤ L3 / L1×2 + L2 ≤ 1 / 2 is set to ensure that the structure of the first clamping block 2 is neither too long nor too short. If L3 is too long relative to the overall length of the first positioning groove 21, the clamping block will occupy too much space, increasing the size and weight of the device, which is not conducive to operation and installation. Conversely, if L3 is too short relative to the overall length of the first positioning groove 21, the clamping block may not be able to provide sufficient support, affecting the clamping stability.

[0040] Optionally, in some embodiments, when L3 / L1 × 2 + L2 = 1 / 3, that is, the length L3 of the first clamping block 2 is relatively short compared with the overall length of the first positioning groove 21, it is suitable for clamping and positioning small irregular glass panels, which can effectively save space and improve production efficiency.

[0041] Optionally, in some embodiments, when L3 / L1 × 2 + L2 = 1 / 2, the length of the first clamping block 2 is relatively longer than the overall length of the first positioning groove 21, which can provide stronger clamping force and is suitable for larger or heavier irregularly shaped glass panels, ensuring stability during the clamping process.

[0042] Furthermore, as a preferred embodiment of this solution and not a limitation, the first positioning groove 21 has a first rounded corner 213 at both ends of its edges, and the first clamping block 2 has a second rounded corner 22 at both ends.

[0043] In this embodiment, the first positioning groove 21 has a first rounded corner 213 at both ends of its edges, and the first clamping block 2 has a second rounded corner 22 at both ends of its edges. Correspondingly, the second positioning groove 31 of the second clamping block 3 also has a rounded corner structure symmetrical to the first rounded corner 213 at both ends of its edges, and the second clamping block 3 also has a rounded corner structure symmetrical to the second rounded corner 22 at both ends of its edges.

[0044] In actual processing, when irregularly shaped glass panels are placed or removed, the edges of the panels may come into contact with both ends of the first positioning groove 21. Without rounded corners, sharp edges may scratch the glass surface or cause stress concentration, leading to panel breakage. The first rounded corners 213 at both ends of the first positioning groove 21 effectively reduce friction and collision between the glass panel and the edge of the positioning groove during insertion and removal of the clamping and positioning device. The contact between the glass panel edges and the rounded corners avoids sharp corners from scratching or damaging the glass panel surface, thus protecting the integrity of the glass panel, improving the yield rate of glass panels, and reducing costs caused by panel damage.

[0045] Furthermore, the rounded corners 22 at both ends of the first clamping block 2 and the corresponding rounded corner structure of the second clamping block 3 prevent the edges and corners of the clamping blocks from becoming sharp. This effectively prevents operators from being scratched by the edges and corners of the clamping blocks when placing or removing glass panels, improving safety during operation, protecting the personal safety of operators, and reducing the probability of workplace accidents.

[0046] Furthermore, as a preferred embodiment of this solution and not a limitation, the first clamping block 2 is provided with a first mounting hole 23 on both its upper and lower parts, which is arranged along its width direction.

[0047] In this embodiment, the first clamping block 2 has first mounting holes 23 on both its upper and lower parts, arranged along its width direction. Correspondingly, the second clamping block 3 also has mounting hole structures corresponding to the first mounting holes 23 on its upper and lower parts, arranged along its width direction. The first mounting holes 23 on the first clamping block 2 provide a convenient installation method for mounting the clamping block to printing equipment or other work platforms. By simply using bolts, screws, or other connectors to pass through the mounting holes for fixing, the first clamping block 2 and the second clamping block 3 can be quickly and accurately installed in the required position, greatly improving installation efficiency and reducing time and labor costs during the installation process.

[0048] Furthermore, as a preferred embodiment of this solution and not a limitation, a second mounting hole 24 is provided in the arc segment L1 of the first clamping block 2, which is arranged along its width direction.

[0049] In this embodiment, the arc segment L1 of the first clamping block 2 is provided with a second mounting hole 24 arranged along its width direction. Correspondingly, the arc segment L1 of the second clamping block 3 is also symmetrically provided with a second mounting hole 24 arranged along its width direction. The position of the second mounting hole 24 in the arc segment L1 is chosen because the arc segment L1 is a key area that contacts the edge of the irregular glass panel during clamping. By setting the mounting hole here, the clamping force can be more effectively distributed, avoiding clamp deformation or panel damage caused by force concentration. The second mounting hole 24 can be used to firmly fix the first clamping block 2 to the equipment platform with bolts, pins or other fasteners to ensure that the clamping and positioning device will not loosen or shift during use. Furthermore, the design of setting the mounting hole in the arc segment L1 allows the clamp to achieve additional fixation in the key force area, further enhancing the overall stability of the device, especially when facing large or heavy irregular glass panels, effectively preventing the clamp from tilting or deforming due to uneven force.

[0050] Optionally, in some other embodiments, a buffer component, such as a rubber pad, can be installed using the second mounting hole 24 to form a buffer layer between the glass panel and the clamping block. This effectively reduces hard contact and friction between the glass panel and the clamping block when clamping the glass panel, preventing scratches or damage to the glass panel surface, protecting the integrity of the glass panel, reducing the defect rate, and improving production efficiency.

[0051] Furthermore, as a preferred embodiment of this solution and not a limitation, both the first clamping block 2 and the second clamping block 3 are made of plastic material.

[0052] In actual glass panel printing production, due to the inherent flexibility and elasticity of plastic materials, when a glass panel is placed within the clamping space formed by the first clamping block 2 and the second clamping block 3, the plastic clamping blocks can adapt to the irregular contours of the glass panel to a certain extent. Through slight deformation, they tightly adhere to the surface of the glass panel, achieving stable clamping. Specifically, the elasticity and cushioning properties of plastic materials, compared to hard materials such as metal, effectively reduce the hard compression and friction on the glass panel surface when clamping it. This prevents scratches and damage to the glass panel surface, protects the integrity of the glass panel, improves product yield, and reduces production costs caused by panel damage.

[0053] Optionally, in some possible embodiments, the first clamping block 2 and the second clamping block 3 can be made of plastic materials such as polyoxymethylene (POM), nylon (PA), or polycarbonate (PC). These materials have high wear resistance and can withstand friction and wear during long-term use, extending the service life of the device. They also have good elasticity, providing a certain cushioning effect during clamping and preventing the glass panel from breaking due to excessive pressure. In addition, compared with metal materials, plastic materials have a lower density, significantly reducing the overall weight of the device and facilitating quick installation and disassembly by operators.

[0054] Furthermore, as a preferred embodiment of this solution and not a limitation, the thickness of the first clamping block 2 and the second clamping block 3 is 17-20 mm, preferably 18 mm. When the thickness of the first clamping block 2 and the second clamping block 3 is within the range of 17-20 mm, it ensures that the clamping blocks have sufficient strength to support and fix the glass panel, while not increasing the overall weight and volume of the device due to excessive thickness, thus affecting the ease of operation. During the printing process of the glass panel, it may be subjected to external forces such as pressure and vibration from the printing equipment. Clamping blocks of appropriate thickness can resist these external forces, prevent deformation or damage to the clamping blocks, ensure stable clamping of the glass panel, thereby improving printing accuracy and quality, and reducing printing deviations and defect rates caused by clamping block instability.

[0055] Working principle of this utility model:

[0056] This invention proposes a clamping and positioning device for irregularly shaped panels. The core components of this device are a first clamping block and a second clamping block arranged symmetrically. The clamping space formed by the two blocks can apply force evenly to the irregularly shaped glass panel from both sides, ensuring panel stability during printing. The positioning groove in the middle of the clamping block can correspond to the irregular part of the panel to achieve precise positioning and prevent displacement or deformation during printing.

[0057] The positioning groove adopts an arc-shaped structure that converges from both ends towards the center, perfectly fitting the curved or curved edges of the panel. This effectively restricts panel movement, reduces pattern deviation, and improves printing accuracy. Simultaneously, this structure ensures even force distribution on the panel, preventing localized damage, enhancing clamping stability, reducing the defect rate, and providing excellent adaptability to irregularly shaped panels with varying curvatures, making it highly versatile. Furthermore, the positioning groove includes both curved and straight sections, allowing for precise adaptation to panels with both curved and straight edges, further ensuring accurate positioning and even force distribution.

[0058] In terms of structural optimization, the device optimizes the ratio of the length of the clamping block to the length of each part of the positioning groove, making the clamping block structure compact and reasonable, balancing clamping stability and space utilization. The rounded corners at both ends of the clamping block and the positioning groove protect the glass panel and ensure the safety of the operator.

[0059] Furthermore, for ease of installation, mounting holes are provided at different positions on the clamping blocks, which not only facilitates installation but also disperses clamping force and enhances stability. The selected plastic material possesses flexibility, elasticity, and cushioning properties, protecting the panel while being wear-resistant, lightweight, and highly elastic, extending the device's lifespan. Through the above design, this device achieves efficient and stable clamping of irregularly shaped glass panels, significantly improving printing accuracy and quality while reducing the defect rate.
