Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass welding technology, and in particular to a sheet welding and pressing device. Background Technology
[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.
[0003] Ultrafast laser welding of glass requires two pieces of glass to be tightly bonded together with a gap smaller than the wavelength of light (usually <1μm), and the fusion welding is achieved by using the evanescent wave generated by light interference at the interface.
[0004] Traditional glass welding often uses mechanical clamps (metal jaws or pressure plates) to directly hold the glass, making it contact through rigid fixation. However, this can easily lead to cracks due to stress concentration. Alternatively, a vacuum adsorption stage can be used to fix a single layer of glass, which relies on surface flatness and makes it difficult to adjust the gap. A few methods use low-melting-point wax or glue for temporary bonding, which results in residual pollution and insufficient gap control precision (usually >10μm), failing to meet the submicron-level bonding requirements of ultrafast laser welding. Utility Model Content
[0005] The purpose of this utility model is to address the aforementioned shortcomings by providing a sheet welding and clamping device that achieves high-precision gap control, non-destructive clamping, high-efficiency operation, and wide adaptability.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a sheet welding and pressing device, comprising: The device body includes a base, a support plate, and a top plate. The top plate is fixedly installed on the base via the support plate, and the top plate is provided with welding holes. A lifting mechanism is mounted on the base; A support plate is installed at the lifting end of the lifting mechanism; Multiple flexible support units are disposed on the bearing plate to form a flexible support surface bearing sheet.
[0007] Furthermore, it also includes a limiting component, which is disposed on the support plate to limit the glass placed on the flexible support unit.
[0008] Furthermore, the limiting component consists of multiple limiting shafts disposed on the top of the support plate and used for positioning the glass to be processed; The top plate is provided with multiple limiting holes, and the limiting shaft corresponds to each limiting hole.
[0009] Furthermore, the flexible support unit consists of multiple silicone spheres arranged in an array.
[0010] Furthermore, the silicone ball is a semi-transparent silicone ball.
[0011] Furthermore, rubber strips are installed on opposite sides of both the top plate and the bearing plate.
[0012] Furthermore, the top plate or support plate is provided with a pressure sensor for detecting the glass clamping pressure.
[0013] Furthermore, the lifting mechanism includes a cylinder and a solenoid valve for controlling the opening and closing of the cylinder's air path. The solenoid valve is used to control the cylinder's air path to disconnect when the stripe density at the glass gap reaches a set threshold.
[0014] Furthermore, there are multiple support plates, which together form a clamping area for clamping the glass. The lifting mechanism is located within the clamping area, and one of the support plates is provided with a pick-and-place port for the glass to enter and exit the clamping area.
[0015] Furthermore, the top plate is arranged parallel to the supporting plate.
[0016] The beneficial effects of this utility model are reflected in: This invention involves placing the glass to be clamped onto a flexible support unit using a limiting component, and then raising the support plate using a lifting mechanism, so that the glass is clamped between the top plate and the support plate. Due to the flexible support unit on the support plate, the contact stress is dispersed by the flexible support, avoiding scratches or microcracks on the glass caused by traditional metal clamps during the clamping process, effectively reducing the surface damage rate, and achieving the effect of non-destructive clamping.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.
[0020] Please see Figure 1-2 This utility model discloses a sheet welding and pressing device, comprising: The device body 1 includes a base 11, a support plate 12 and a top plate 13. The top plate 13 is fixedly installed on the base 11 via the support plate 12, and the top plate 13 is provided with welding holes. Lifting mechanism 2 is installed on base 11; The support plate 3 is installed at the lifting end of the lifting mechanism 2; Multiple flexible support units 4 are disposed on the bearing plate 3 to form a flexible support surface bearing sheet.
[0021] It also includes a limiting component 5, which is located on the support plate 3 and limits the glass placed on the flexible support unit 4.
[0022] This invention involves placing the glass to be clamped onto the flexible support unit 4 using the limiting component 5, and then raising the support plate 3 using the lifting mechanism 2, so that the glass is clamped between the top plate 13 and the support plate 3. Due to the flexible support unit 4 on the support plate 3, the contact stress is dispersed by the flexible support, avoiding scratches or microcracks on the glass caused by traditional metal clamps during the clamping process, effectively reducing the surface damage rate, and achieving the effect of non-destructive clamping.
[0023] In one embodiment, the limiting component 5 consists of a plurality of limiting shafts disposed on the top of the support plate 3 and used for positioning the glass to be processed; The top plate 13 is provided with multiple limiting holes, and the limiting shaft corresponds to the limiting hole one by one.
[0024] This design, by arranging multiple limiting shafts on three sides of the flexible support surface and reserving the other side as the side for picking up and placing the glass to be processed, allows the glass to be processed to be placed on the flexible support surface and then quickly positioned by pushing the glass to be processed against the limiting shafts on the three sides.
[0025] Specifically, in addition to the limiting shaft, the limiting component 5 can also be a limiting baffle or a combination of the limiting baffle and the limiting shaft. The limiting baffle can be designed with an adjustable angle and position to adapt to glass of different shapes and sizes, improving the versatility of the device. The adjustment method of the position and angle of the limiting baffle is not specifically limited, as long as it meets the positioning requirements of the glass sheet. The limiting shaft can be equipped with anti-slip textures or a rubber coating to enhance the friction between it and the glass, prevent the glass from sliding during the positioning process, and improve the accuracy and stability of the positioning.
[0026] In one embodiment, the flexible support unit 4 consists of multiple silicone spheres arranged in an array.
[0027] This design allows the array of silicone spheres to adapt to the slight deformation of the glass. Furthermore, by adjusting the distribution of the array of multiple silicone spheres, rectangular, circular, or ring arrays can be selected according to requirements, making the resulting flexible support surface compatible with glass of greater thickness, shape, and size, thus achieving a wide range of applicability.
[0028] In one embodiment, the silicone ball is a translucent silicone ball.
[0029] This design makes the silicone ball translucent, allowing the laser to pass through while preventing heat absorption and burns to the silicone ball.
[0030] In one embodiment, rubber strips are installed on opposite sides of the top plate 13 and the support plate 3.
[0031] This design, by adding rubber strips to disperse clamping stress, further reduces the surface damage rate of the glass, while increasing the friction of the contact surface to prevent displacement of the glass during fixing. Specifically, the rubber strips can be arranged according to the welding edge and matched with the welding trajectory. The shape and installation position of the rubber strips are not specifically limited, as long as they meet the requirements for fixing the glass sheet.
[0032] Furthermore, the rubber strip can be replaced with a silicone strip that has the same high-temperature resistance and elasticity.
[0033] In one embodiment, a pressure sensor for detecting glass clamping pressure is provided on the top plate 13 or the support plate 3.
[0034] This design uses a pressure sensor to monitor the clamping force on the glass, thereby controlling the lifting mechanism 2 to stop moving when the clamping force exceeds a set threshold, thus improving safety.
[0035] Specifically, the pressure sensors installed on the top plate 13 or the support plate 3, in addition to detecting the glass clamping pressure, can also have a pressure distribution detection function. By arranging multiple pressure sensors in an array, the pressure distribution on the glass surface can be monitored in real time, and the data is transmitted to the control system for analysis and processing. When the pressure distribution is uneven, the control system can automatically adjust the movement of the lifting mechanism 2 based on the feedback information to make the glass more evenly stressed, further improving the clamping quality and welding effect. At the same time, it also helps to detect some defects or damage to the glass in a timely manner, avoiding glass damage caused by improper clamping.
[0036] In one embodiment, the lifting mechanism 2 includes a cylinder and a solenoid valve for controlling the opening and closing of the cylinder's air path. The solenoid valve is used to control the cylinder's air path to disconnect when the stripe density at the glass gap reaches a set threshold.
[0037] With this design, after two pieces of glass are stacked on the silicone ball, the cylinder is activated to push the support plate 3 upward until the upper glass contacts the top plate 13. Then, the cylinder is finely adjusted to compress the silicone ball and reduce the gap between the glass pieces. The colored interference fringes on the interface are monitored visually or by a camera. The interference fringes provide visual feedback and are linked with the cylinder. When the fringes density reaches a set threshold, the cylinder is locked in time by controlling the solenoid valve, which can quickly complete the clamping and calibration. Compared with manual adjustment, the efficiency is greatly improved. Moreover, no adhesive or vacuum assistance is required, and there is no residual pollution, achieving the goal of high-efficiency operation.
[0038] Specifically, in addition to using a combination of cylinders and solenoid valves, the lifting mechanism 2 can also employ a screw and nut mechanism or a rack and pinion mechanism to achieve the lifting motion. The screw and nut mechanism offers high transmission accuracy and stability, allowing for precise control of the screw's rotation angle to achieve minute lifting of the bearing plate 3, thus enabling more accurate adjustment of the glass clamping force. The rack and pinion mechanism provides greater lifting force, suitable for clamping heavier glass, and its compact structure makes it easy to integrate with other components. The specific structural composition of the screw and nut mechanism or the rack and pinion mechanism is not limited, as long as it meets the requirements for lifting the glass sheet.
[0039] It should be noted that after the cylinder pushes the glass to contact the top plate 13, the amount of compression of the silicone ball determines the gap size (theoretical formula: gap h ≈ (F·d) / (E·A·N), where F is the cylinder force, d is the diameter of the silicone ball, E is the elastic modulus, A is the contact area, and N is the number of balls). Through the synergistic effect of the elastic compression of the silicone ball and the fine adjustment of the cylinder, the glass gap can be precisely adjusted at the sub-micron level, meeting the λ / 4 optical conditions for ultrafast laser interference welding, thereby effectively improving the glass welding yield.
[0040] In one embodiment, there are multiple support plates 12, which together form a clamping area for clamping glass. The lifting mechanism 2 is located within the clamping area, and one of the support plates 12 is provided with a pick-and-place opening for glass to enter and exit the clamping area.
[0041] This design, by aligning the pick-up and drop-off ports with the pick-up and drop-off sides reserved by multiple limiting shafts, makes it convenient for operators to pick up and drop glass from the outside into the clamping area.
[0042] In one embodiment, the top plate 13 is arranged parallel to the support plate 3, and the lower surface of the top plate 13 is polished.
[0043] This design further improves the stability of the glass during clamping and reduces damage to the glass surface.
[0044] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
[0045] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
[0046] Additionally, "multiple" refers to two or more.
