[0031] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0032] Reference below Figure 1-Figure 4 A vacuum clamp for processing mobile equipment according to an embodiment of the present invention is described.

[0033] like Figure 1-Figure 4 As shown, the mobile equipment processing vacuum fixture includes a base 110 and a mounting base 130. The mounting base 130 is arranged above the base 110. The mounting base 130 is installed on the base 110 through a column 120. The base 110 is fixed on the workpiece table of the processing equipment.

[0034] A fixture base 210 is removably mounted on the mounting base 130 and is mounted on the surface of the mounting base 130. The center of the fixture base 210 serves as a clamping area, while the periphery serves as a limiting area. Vacuum adsorption grooves 220 are located within the clamping area, and removably connected limiting blocks 230 surround the limiting area. Specifically, the vacuum fixture is secured by vacuum adsorption, while the limiting blocks 230 are used to quickly locate the contour of the workpiece, preventing it from loosening during machining and affecting processing quality.

[0035] The vacuum adsorption groove 220 is provided with a detachable adsorption gasket 223, which is used to adjust the adsorption area of the vacuum adsorption groove 220. When the limit block 230 is installed in the limit area, the limit block 230 is located in the clamping area near the side wall of the clamping area, and the edge of the clamping area is the maximum clamping range.

[0036] Specifically, when there is a raised structure on the back of the workpiece, the vacuum adsorption groove 220 cannot completely fit with the back of the workpiece. The adsorption gasket 223 is used to change the position of the adsorption port to adsorb the flat area on the back of the workpiece, thereby improving the applicability of the vacuum clamp.

[0037] This new vacuum fixture for mobile device processing is primarily used for clamping mobile phone frames. By combining the stopper blocks 230, it can clamp mobile phone frames ranging from 4.7 inches to 7 inches, meeting the requirements of most mobile phone sizes on the market. The suction gasket 223 addresses the issue of the back surface area of the mobile phone frame being offset due to the protrusion of the camera module. Compared to existing dedicated, non-standard fixtures, this new fixture only requires selecting the corresponding stopper blocks 230 and suction gaskets 223 according to the processing specifications to achieve clamping, saving significant fixture manufacturing costs and adjustment time, and improving processing efficiency.

[0038] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the vacuum adsorption groove 220 is provided with at least two vacuum exhaust holes 221, and an exhaust pipe 222 is provided at the position corresponding to the vacuum exhaust hole 221 at the bottom of the mounting seat 130. The exhaust pipe 222 is connected to the vacuum exhaust hole 221. The exhaust pipe 222 is used to connect to an external vacuum pumping mechanism and vacuum the vacuum adsorption groove 220.

[0039] Specifically, in this embodiment, three vacuum exhaust holes 221 are provided, arranged side by side within the vacuum adsorption tank 220. When the back of the workpiece covers the vacuum adsorption tank 220, the exhaust pipe 222, through an external vacuum pumping mechanism, evacuates the air within the vacuum adsorption tank 220, creating a negative pressure state, thereby pressing the workpiece tightly against the clamping area. This, combined with the workpiece contour surrounded by the stop block 230, allows the workpiece to be securely clamped to the fixture base 210.

[0040] Furthermore, the adsorption gasket 223 is made of rubber, and its thickness is not less than the depth of the vacuum adsorption groove 220. Specifically, the adsorption gasket 223 is made of elastic rubber. When the workpiece is in a vacuum adsorption state, the adsorption gasket 223 is squeezed and deformed by the workpiece, thereby filling the connection gap between the adsorption gasket 223 and the workpiece.

[0041] Furthermore, the suction gasket 223 typically uses a uniform outer diameter structure to absorb the workpiece. When the workpiece's back surface is severely offset, the suction gasket 223 adopts a stepped structure with a gradually decreasing outer diameter from bottom to top, which is used to reduce the contact area for vacuuming and facilitates the absorption of workpieces with uneven back surfaces.

[0042] In some embodiments of the present invention, Figure 3As shown, the fixture seat 210 is provided with a positioning pin 214, and the mounting seat 130 is provided with a positioning hole 131 corresponding to the position of the positioning pin 214. The positioning pin 214 and the positioning hole 131 are plugged into each other to position and install the mounting seat 130 so as to align the positions of the vacuum exhaust hole 221 and the exhaust pipe 222.

[0043] Specifically, the fixture base 210 and the mounting base 130 are quickly positioned and installed using the positioning pins 214 and positioning holes 131, ensuring that the vacuum exhaust hole 221 and the exhaust pipe 222 are aligned. This also facilitates the replacement of fixture bases 210 of different specifications. When using a fixture base 210 with a clamping plate specification, the fixture base 210 can be quickly replaced, improving efficiency.

[0044] In some embodiments of the present invention, Figure 1 、 Figure 3 and Figure 4 As shown, the limiting area is provided with a clamping groove 213, and the limiting block 230 is installed in the clamping groove 213. Specifically, the width of the clamping groove 213 matches the width of the limiting block 230, and the length of the limiting block 230 is adjusted according to different workpiece specifications.

[0045] Furthermore, if Figure 1 and Figure 3 As shown, the clamping groove 213 includes a top clamping groove 213a, a side clamping groove 213b and a bottom clamping groove 213c, and the limit block 230 includes a top block 231, a side block 232 and a bottom block 233. The corresponding limit block 230 is connected to the corresponding clamping groove 213 by screws.

[0046] Specifically, the top stopper 231 is a U-shaped block, and the inner width of the top stopper 231 matches the width of the workpiece, which can better limit the position of the workpiece in the clamping area.

[0047] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the fixture seat 210 is provided with a loading trough 215 on both sides of the clamping area, and the loading trough 215 is used for loading and unloading the workpiece in the clamping area. Specifically, the manipulator clamps the two sides of the workpiece from the loading trough 215 to realize the picking and placing of the workpiece.

[0048] In some embodiments of the present invention, Figure 1 、 Figure 3 and Figure 4 As shown, the fixture seat 210 is provided with a label slot 216, which is communicated with the clamping area. The label slot 216 is used to place a label and attach it to the workpiece.

[0049] Specifically, the label in the label slot 216 extends to the clamping area. When the workpiece is clamped to the fixture seat 210, the back of the workpiece is in contact with the label. After the workpiece is processed, it enters the next process with the label.

[0050] Throughout this specification, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or example are included in at least one embodiment or example of the present invention.
