Description

Technical Field

[0001] This utility model relates to the field of vacuum adsorption fixture technology, and in particular to a vacuum adsorption fixing fixture. Background Technology

[0002] Vacuum clamping systems are commonly used for the rapid clamping of wood, plastics, and non-ferrous metals. They are compatible with CNC machine tools, do not damage the clamping surfaces, and eliminate the need for time-consuming and laborious workpiece alignment. They are frequently used for assembling semiconductor chips and other small electronic components onto circuit boards.

[0003] Common adsorption fixtures often feature a fixed vacuum adsorption station design. After adsorbing and fixing circuit boards or electronic components through the nozzle, they can only remain in place and can only be operated by controlling other components on them. Consequently, they cannot be quickly moved to the corresponding station for different processes, resulting in poor flexibility. In addition, different electronic components have different sizes, and conventional nozzles with a uniform diameter cannot adsorb smaller parts. When adsorbing larger parts, the adsorption surface is too small in proportion to the overall size, and the stress at the adsorption point is relatively greater, making it prone to deformation and damage during operation. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum adsorption fixture that can quickly adjust the vacuum adsorption area, thereby enabling the selection of more suitable suction cups for stable adsorption and fixation of electronic components of different sizes. In addition, it allows for handheld adsorption operations, and after adsorption and fixation of electronic components, they can be freely transferred within a certain range, facilitating the rapid transfer of components to different processes and improving the flexibility of the fixture.

[0005] To achieve the above objectives, a vacuum adsorption fixing fixture is provided, comprising: a vacuum pump, a base fitted and fixed to the bottom of the vacuum pump, a flexible tube connected and fixed to the upper right output end of the vacuum pump, a tight connector connected and fixed to the right end of the flexible tube, a high-pressure resistant tube connected and fixed to the right side of the tight connector, an on / off valve connected and fixed to the right end of the high-pressure resistant tube, a rigid vacuum nozzle connected and fixed to the right side of the on / off valve, an adsorption head threadedly connected to the right side of the rigid vacuum nozzle, a frame plate fixedly connected to the middle right side of the vacuum pump, L-shaped hooks symmetrically fixed to the upper and lower right sides of the frame plate, a semi-circular hopper vertically fixed to the top right side of the base, a semi-circular cover fitted and mounted on the front side of the semi-circular hopper, and a hinge on the left side of the semi-circular cover. The device rotates in conjunction with a semi-circular silo. An opening is located at the top of the semi-circular silo opposite the semi-circular cover. A semi-circular rubber sleeve is symmetrically mounted on the inner side of the opening. The opposite side of the semi-circular rubber sleeve is fixedly connected to both the semi-circular silo and the semi-circular cover. By using a rigid vacuum nozzle and engaging with several externally expanding and internally contracting suction cups of different diameters, the vacuum adsorption area can be quickly adjusted. This allows for the selection of more suitable suction cups for stable adsorption and fixation of electronic components of different sizes. Additionally, a high-pressure resistant tube is used in conjunction with a flexible tube for handheld adsorption operations. After adsorption and fixation of electronic components, they can be freely transferred within a certain range, facilitating rapid transfer of components to different processes and improving the flexibility of the fixture.

[0006] According to the aforementioned vacuum adsorption fixing fixture, the adsorption head includes several outwardly expanding suction cups and inwardly contracting suction cups of different diameters. Each of the outwardly expanding and inwardly contracting suction cups has a threaded ring fixedly connected to its left side. These threaded rings extend into the inner wall of the vacuum nozzle and are threadedly connected thereto. This allows for the selection of more suitable suction cups for stable adsorption and fixing of electronic components of different sizes.

[0007] According to the aforementioned vacuum adsorption fixing fixture, sealing gaskets are fitted and fixed at the inner right edge of both the outward-expanding suction cup and the inward-retracting suction cup, and the sealing gaskets are flexibly pressed and adhered to the outer surface of the component. This facilitates gentler contact with the outer surface of the electronic component for sealing and adsorption.

[0008] According to the aforementioned vacuum adsorption fixing fixture, an external collar is fixedly connected to the bottom of the sealing joint. The inner side of the external collar is threaded and docked with an external robotic arm for fixation. This provides a docking basis for the handheld component to be connected with automated machinery.

[0009] According to the aforementioned vacuum adsorption fixing fixture, a base support is fitted into the inner bottom of the semi-circular silo, and an inverted frustum-shaped groove is provided at the top center of the base support. This facilitates the flexible compression and placement of the rigid vacuum nozzle along with the adsorption head.

[0010] According to the aforementioned vacuum adsorption fixing fixture, a handle is fixedly connected to the middle right side of the semi-circular cover, and an anti-slip sleeve is fixedly attached to the middle outer side of the high-pressure resistant tube. This facilitates opening and closing the semi-circular cover and holding the high-pressure resistant tube.

[0011] According to the aforementioned vacuum adsorption fixing fixture, counterweight pads are symmetrically fitted and fixed to the bottom of the base, and each counterweight pad has anti-slip texture on its bottom surface. This lowers the overall center of gravity and improves stability.

[0012] According to the aforementioned vacuum adsorption fixing fixture, a dust cover is horizontally fixed to the top of the vacuum pump, and an anti-collision rubber ring is fixed around the outside of the dust cover. This provides dust protection for the vacuum pump and its connecting structure while also providing flexible anti-collision protection for its edges.

[0013] The above-mentioned solution has the following beneficial effects:

[0014] In this invention, a rigid vacuum nozzle is used in conjunction with several externally expanding and internally contracting suction cups of different diameters to quickly adjust the vacuum adsorption area. This allows for the selection of more suitable suction cups for stable adsorption and fixation of electronic components of different sizes. In addition, a high-pressure resistant tube is used in conjunction with a flexible tube for handheld adsorption. After adsorption and fixation of electronic components, they can be freely transferred within a certain range, facilitating the rapid transfer of components to different processes and improving the flexibility of the fixture.
