DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-6 This application is described in further detail.

[0038] The present application embodiment discloses a vacuum circuit fixture. Figure 1 The vacuum circuit fixture includes a vacuum stage 1, a plurality of knobs 2, and a plurality of vacuum suction cups 3. The vacuum stage is provided with a connecting hole 4 and a vacuum channel 5. In some embodiments, the vacuum stage includes a stage seat 11 and a stage cover 12. The vacuum channel 5 is provided on the stage seat 11, and the stage cover 12 is sealed and fixedly connected to the stage seat 11. After the stage seat 11 is processed, the stage cover 12 is sealed and fixedly connected to the stage seat 11, so as to further reduce the processing difficulty.

[0039] The vacuum channel 5 includes a main channel 51 and a plurality of branch channels 52 connected to the main channel 51. The main channel 51 is connected to the connecting hole 4. The connecting hole 4 is connected to a vacuum pipe on the side away from the vacuum channel 5 for connecting to external vacuum equipment.

[0040] Reference Figure 1 and Figure 2 , at least two vacuum suction cups 3 are spaced apart on the main channel 51. In this embodiment, the vacuum suction cups 3 are installed on the stage cover 12, and two vacuum suction cups 3 are spaced apart on the main channel 51 and are located on both sides of one row of branches. Each branch channel 52 corresponds to a vacuum suction cup 3, and is located at one end of the branch channel 52 away from the main channel 51, and a knob 2 is correspondingly set between the vacuum suction cup 3 of each branch channel 52 and the main channel 51, and the knob 2 is used to open or close the corresponding branch channel 52.

[0041] In some embodiments, the branch channels 52 extend along the width direction of the main channel 51 and are arranged at intervals along the length direction. In this embodiment, branch channels 52 are arranged on both sides of the width direction of the main channel 51 and are arranged perpendicular to the length direction of the main channel 51; and three groups are arranged at intervals along the length direction, and the length of the middle group is greater than the length of the groups on both sides. In other embodiments, one group, two groups or several groups can be arranged as needed, and the length can also be set according to actual needs.

[0042] Therefore, independent control of different areas of the workpiece can be achieved; by controlling the opening or closing of the branch channel 52 through the knob 2, the user can easily adjust the vacuum degree of different areas to adapt to workpieces of different shapes, sizes and weights, greatly improving the applicability of the fixture; the branch channels 52 arranged at intervals make maintenance and repair work easier. When a branch channel 52 or knob 2 fails, it can be repaired or replaced separately without affecting the normal operation of other channels; the layout of the branch channels 52 fully considers the efficiency of space utilization. They are neither too dense to cause inconvenience in operation nor too sparse to waste space. This reasonable spatial layout makes the entire fixture more compact and efficient.

[0043] In some embodiments, both ends of the main channel 51 in the length direction are connected with auxiliary channels 6, the auxiliary channels 6 extend in the width direction of the main channel 51, and are arranged perpendicular to the length direction of the main channel 51, and the branch channels 52 are arranged at intervals along the length direction of the auxiliary channels 6. In this embodiment, three branch channels 52 are arranged at intervals along the auxiliary channels 6. Through the combined design of the auxiliary channels 6 and the branch channels 52, the fixture can achieve precise adsorption control of different areas, shapes and sizes of the workpiece, greatly improving the flexibility and applicability of the fixture; it helps to reduce the resistance and loss of vacuum transmission, improve the efficiency of vacuum transmission, and thus ensure that the workpiece remains stable during processing or testing; the modular design makes it easier to maintain and expand the fixture, and when it is necessary to adjust the adsorption area or add new functions, it can be achieved by adding or adjusting the auxiliary channels 6 and the branch channels 52.

[0044] Reference Figure 3 and Figure 4 In some embodiments, the vacuum stage 1 is provided with a mounting groove 7, which is connected to the branch channel 52 between the vacuum suction cup 3 and the main channel 51. The diameter of the mounting groove 7 is larger than the opening width of the branch channel 52. The knob 2 is sealed and inserted into the mounting groove 7 and is rotatably connected to the vacuum stage. The branch channel 52 is opened or closed by rotating the knob 2. The rotation connection mode of the knob 2 makes it easy to adjust the adsorption state of the vacuum suction cup 3 by rotation, which improves the convenience and efficiency of the operation; the design of the mounting groove 7 enables the knob 2 to be compactly installed on the vacuum stage, thereby optimizing the space utilization of the fixture, making the entire fixture more compact and efficient.

[0045] In some embodiments, the knob 2 is interference-fitted with the vacuum stage 1, which can ensure close contact between the knob 2 and the vacuum stage 1, reduce air or vacuum leakage, and thus improve the sealing performance of the fixture.

[0046] Reference Figure 4 In some embodiments, the knob 2 is provided with a communication port 8. When the knob 2 is rotated until the communication port 8 is connected to the branch channel 52, the branch channel 52 is opened. Figure 5 When the knob 2 is rotated until the communication port 8 abuts against the wall of the mounting groove 7, the branch channel 52 is closed. The rotation of the knob 2 controls the connection or closing of the communication port 8 and the branch channel 52, realizing precise control of vacuum transmission. The user can open or close the branch channel 52 at any time as needed to meet different processing or testing requirements; the design of the knob 2 and the mounting groove 7 makes the structure of the entire vacuum circuit fixture more compact, saving space and improving the overall aesthetics.

[0047] Reference Figure 6In some embodiments, an indicator groove 9 is provided on the knob 2, and the length direction of the indicator groove 9 is consistent with the opening direction of the connecting port 8. By observing the position of the indicator groove 9, it can be intuitively judged whether the connecting port 8 is currently connected to the branch channel 52, and the indicator groove 9 can be used to conveniently rotate the knob 2 to a corresponding angle.

[0048] Reference Figure 6 In some embodiments, a sealing groove 10 is provided on the circumference of the knob 2, and a sealing ring 13 is provided in the sealing groove 10. The sealing ring 13 can realize a better sealing connection between the knob 2 and the vacuum stage 1, thereby improving the sealing effect; the sealing groove 10 can also guide the sealing ring 13 to deform when subjected to pressure, so as to better fill the sealing gap.

[0049] Reference Figure 5 and Figure 6 In some embodiments, at least two sealing grooves 10 are provided on the sides of the knob 2, and sealing rings are provided correspondingly. In this embodiment, two sealing grooves 10 are provided and are located on both sides of the connecting port 8, and correspond to the carrier seat 11 and the carrier cover 12 respectively, so that a better seal can be formed on both sides of the connecting port 8, so that the vacuum operation can be better performed.
