Technical Field
[0001] This utility model relates to the field of circuit board technology, and in particular to an adsorption clamp for glass-based circuit boards. Background Technology
[0002] In the processing, inspection, and assembly of glass-based circuit boards, stable fixation is required to ensure operational accuracy. A vacuum adsorption fixture for glass-based circuit boards has emerged to address this need. This type of fixture utilizes the principle of vacuum adsorption to achieve reliable fixation without damaging the surface and edges of the glass-based circuit board. It meets the stringent positioning requirements of high-precision machining and is widely used in precision manufacturing fields such as semiconductor packaging and display panel manufacturing. It is one of the key pieces of equipment for ensuring the production quality and efficiency of glass-based circuit boards.
[0003] In existing technologies, adsorption fixtures for fixing glass-based circuit boards typically include a base, an adsorption platform, and a vacuum generator. The adsorption platform has multiple adsorption holes on its surface, which are connected to the vacuum generator via pipes. When the vacuum generator operates, a negative pressure is created within the adsorption holes, using atmospheric pressure to firmly adsorb the glass-based circuit board onto the adsorption platform. To prevent impurities from entering the adsorption holes, some fixtures incorporate fixed filter structures at the adsorption holes, such as attaching a filter screen or welding a metal mesh at the hole inlet.
[0004] However, after long-term use, glass fragments, dust and other impurities easily accumulate on the surface of the filter screen, requiring regular cleaning or replacement. However, since the filter screen is fixedly connected to the adsorption holes, the disassembly process is cumbersome and often requires the use of tools. This not only increases the workload of maintenance personnel, but also affects production efficiency due to frequent downtime for maintenance. There are also problems such as the adsorption holes being easily blocked by impurities and the dustproof screen being inconvenient to disassemble and assemble. To address these issues, an adsorption clamp for glass-based circuit boards is proposed. Summary of the Invention
[0005] To overcome the above shortcomings, this utility model provides an adsorption clamp for glass-based circuit boards, which aims to improve the problems of adsorption holes being easily blocked by impurities and dustproof mesh being inconvenient to install and remove in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An adsorption clamp for glass-based circuit boards includes a base plate, an adsorption clamp body is provided on the side wall of the base plate, a dustproof component is provided inside the adsorption clamp body, and a rotating component is provided on the side wall of the base plate.
[0008] The dustproof component includes a dustproof net, and the adsorption clamp body has multiple adsorption holes inside. The sidewall of the dustproof net is slidably connected to the adsorption holes. A neodymium iron boron magnet is fixedly connected inside the adsorption clamp body. The neodymium iron boron magnet is located at the adsorption hole. A fixing ring is fixedly connected inside the adsorption hole. An iron-nickel alloy magnetic sheet is fixedly connected to the sidewall of the dustproof net. A fixing rod is fixedly connected to the sidewall of the dustproof net.
[0009] As a further description of the above technical solution:
[0010] The rotating assembly includes a rotating rod, and a fixed frame is fixedly connected to the upper surface of the base plate. The side wall of the rotating rod is rotatably connected inside the fixed frame.
[0011] As a further description of the above technical solution:
[0012] A connecting rod is fixedly connected to the side wall of the rotating rod, and the side wall of the connecting rod is rotatably connected inside the fixed frame.
[0013] As a further description of the above technical solution:
[0014] The upper surface of the base plate is fixedly connected to the bottom of the adsorption fixture body with a shock-absorbing pad.
[0015] As a further description of the above technical solution:
[0016] The sidewall of the shock-absorbing pad is fixedly connected to a connecting frame, and hydraulic rods are fixedly connected between the connecting frames.
[0017] As a further description of the above technical solution:
[0018] The side wall of the connecting rod is fixedly connected to the bottom of the adsorption clamp body, and the output end of the hydraulic rod is connected to the connecting frame above.
[0019] As a further description of the above technical solution:
[0020] The bottom of the iron-nickel alloy magnetic sheet is attached to the side wall of the fixing ring, and the iron-nickel alloy magnetic sheet is attracted to the neodymium iron boron magnet.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, the dustproof net is slid into the adsorption hole by a fixing rod, and the iron-nickel alloy magnetic sheet is inserted and attached to the fixing ring. The neodymium iron boron magnet attracts the magnetic sheet to fix the dustproof net. When the adsorption hole is connected to the vacuum equipment to generate negative pressure to adsorb the circuit board, the dustproof net intercepts impurities. When it needs to be cleaned or replaced, it can be taken out by the fixing rod. This solves the problem that the adsorption hole is easily blocked by impurities and the dustproof net is inconvenient to disassemble and assemble. The above technical solution improves the maintenance efficiency of the adsorption fixture.
[0023] In this invention, when an angle needs to be rotated, the hydraulic rod is activated, which extends and retracts to drive the connecting frame, thereby driving the adsorption fixture body. This causes the connecting rod to rotate around the rotating rod inside the fixed frame, thus achieving angle adjustment. The shock-absorbing pad absorbs vibration, and the fixed frame supports the rotating rod and the connecting rod. This solves the problems of inconvenient angle adjustment of the adsorption fixture and the vibration that easily occurs during rotation, affecting processing accuracy. The above technical solution improves the flexibility of angle adjustment of the adsorption fixture. Attached Figure Description

[0031] 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 some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1-3This utility model provides an embodiment of an adsorption clamp for glass-based circuit boards, comprising a base plate 1, which supports the adsorption clamp body 2 and a rotating assembly, thus providing a stable mounting foundation for the entire device. The adsorption clamp body 2 is mounted on the side wall of the base plate 1, and is used to support the glass-based circuit board. Adsorption force is generated through internal adsorption holes 3 to fix the circuit board, providing an operating platform for the processing and testing of the circuit board. A dustproof assembly is provided inside the adsorption clamp body 2, and a rotating assembly is provided on the side wall of the base plate 1. The dustproof assembly includes a dustproof mesh 7, which directly intercepts impurities entering the adsorption holes 3, preventing impurities from clogging the adsorption holes 3 and maintaining the ventilation of the adsorption holes 3. Multiple adsorption holes 3 are opened inside the adsorption clamp body 2, which are used to connect with external vacuum equipment to form a negative pressure, thereby generating adsorption force to firmly fix the glass-based circuit board to the surface of the adsorption clamp body 2, achieving stable clamping of the circuit board. The side wall of the dustproof mesh 7 is slidably connected to the adsorption holes. Inside the adsorption fixture body 2, a neodymium iron boron magnet 4 is fixedly connected. The neodymium iron boron magnet 4 is used to adsorb the iron-nickel alloy magnetic conductive sheet 6, thereby fixing the dustproof net 7 in the adsorption hole 3 and preventing the dustproof net 7 from falling off during the adsorption operation. The neodymium iron boron magnet 4 is set at the adsorption hole 3, and a fixing ring 5 is fixedly connected inside the adsorption hole 3. The fixing ring 5 is used to support and limit the iron-nickel alloy magnetic conductive sheet 6, thereby ensuring the accurate adsorption position of the iron-nickel alloy magnetic conductive sheet 6 and the neodymium iron boron magnet 4. The dustproof net 7 is fixed to the side wall. A nickel-iron alloy magnetic sheet 6 is connected to the dustproof net 7, which is used to fix the dustproof net 7 in conjunction with the neodymium iron boron magnet 4, thereby realizing the quick installation and removal of the dustproof net 7 and facilitating the cleaning or replacement of the dustproof net 7. A fixing rod 8 is fixedly connected to the side wall of the dustproof net 7, which provides a gripping point for the operator, so as to facilitate the removal or insertion of the dustproof net 7 from the adsorption hole 3. The bottom of the nickel-iron alloy magnetic sheet 6 is attached to the side wall of the fixing ring 5, and the nickel-iron alloy magnetic sheet 6 is attracted to the neodymium iron boron magnet 4.
[0033] Reference Figures 4-5The rotating assembly includes a rotating rod 10, which serves as a pivot point to support the connecting rod 11, thus providing a rotation center for adjusting the angle of the adsorption clamp body 2. A fixing frame 9 is fixedly connected to the upper surface of the base plate 1. The side wall of the rotating rod 10 is rotatably connected inside the fixing frame 9, and a connecting rod 11 is fixedly connected to the side wall of the rotating rod 10. The connecting rod 11 connects the rotating rod 10 and the adsorption clamp body 2, thereby transmitting the rotation of the rotating rod 10 to the adsorption clamp body 2 to achieve angle adjustment of the adsorption clamp body 2. The side wall of the connecting rod 11 is rotatably connected inside the fixing frame 9, and the side wall of the connecting rod 11 is fixedly connected to the bottom of the adsorption clamp body 2. A shock-absorbing pad 12 is fixedly connected to the bottom of the adsorption fixture body 2 on the upper surface of the plate 1. The shock-absorbing pad 12 is used to absorb the vibration generated during the rotation of the adsorption fixture body 2, thereby reducing the impact of vibration on the processing accuracy of the glass-based circuit board. A connecting frame 13 is fixedly connected to the side wall of the shock-absorbing pad 12. The connecting frame 13 is used to connect the shock-absorbing pad 12 and the hydraulic rod 14, thereby stably transmitting the driving force of the hydraulic rod 14 to the adsorption fixture body 2. The hydraulic rod 14 is fixedly connected between the connecting frames 13. The output end of the hydraulic rod 14 is connected to the upper connecting frame 13. The hydraulic rod 14 is used to provide power to drive the adsorption fixture body 2 to rotate, thereby achieving precise angle adjustment.
[0034] Working principle: The dustproof net 7 is slid into the adsorption hole 3 by the fixing rod 8. The iron-nickel alloy magnetic sheet 6 enters with the dustproof net 7 and fits with the fixing ring 5. The neodymium iron boron magnet 4 adsorbs the iron-nickel alloy magnetic sheet 6 to fix the dustproof net 7. When the adsorption hole 3 is connected to the external vacuum equipment to generate negative pressure to adsorb the glass-based circuit board, the dustproof net 7 intercepts impurities. When the dustproof net 7 needs to be cleaned or replaced, it can be taken out from the adsorption hole 3 with the help of the fixing rod 8.
[0035] When the angle needs to be rotated, the hydraulic rod 14 is activated, and its extension and retraction drive the connecting frame 13 to move. The upper connecting frame 13 drives the adsorption clamp body 2, causing the adsorption clamp body 2 to drive the connecting rod 11 to rotate around the rotating rod 10 inside the fixed frame 9, thereby realizing the angle adjustment of the adsorption clamp body 2. The shock-absorbing pad 12 absorbs vibration during this process, and the fixed frame 9 provides support for the rotating rod 10 and the connecting rod 11.
