Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully below. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Please refer to fig. 1, fig. 2, fig. 3 and fig. 4, which are schematic diagrams of a fixing device specially used for processing a middle frame of an electronic device according to a preferred embodiment of the present invention, for fixing the middle frame to facilitate processing and production thereof.

A plurality of absorption cavity holes 210 penetrating up and down are formed in the bearing plate body 20, lower ports of the absorption cavity holes 210 are commonly communicated with an air exhaust port 30, and the air exhaust port 30 is connected with an output end pipeline of an air exhaust pump (not shown). Like this, alright closely adsorb the center on the surface of bearing plate body through the cooperation of aspiration pump, port of bleeding, absorption accent to guarantee the laminating effect of center and bearing plate body.

In addition, a plurality of pressing bodies 40 are included, which are arranged to surround the bearing plate body 20, and the pressing bodies 40 are reciprocated up and down by a lift cylinder 50 so that the pressing bodies 40 can be clamped or separated from the bearing plate body 20. In this way, the edges of the middle frame are pressed against the surface of the bearing plate body by controlling the pressing bodies, so as to further strengthen the fixation of the middle frame.

In a further preferred embodiment of the present invention, as shown in fig. 4, the bottom of the bearing plate 20 is recessed inwards to form an air-pumping chamber 230, and the air-pumping chamber 230 is sealed by a sealing plate 240; the pumping chamber 230 communicates upwardly with the plurality of adsorption wells 210 and downwardly with the pumping port 30. It should be noted that the diameter of the adsorption cavity is not designed to be large, and during the vacuum pumping process by the air pump, a situation that the suction force generated at the adsorption cavity is too low to well adsorb the middle frame on the surface of the carrier plate may occur, so that the air pumping cavity is designed to appropriately increase the vacuum pumping area, thereby improving the suction effect and shortening the vacuum forming time.

Further, in order to prevent the air leakage phenomenon from occurring at the connection between the pumping chamber 230 and the sealing plate body 240 to affect the pumping process, a ring of recessed channels 250 is disposed at the outer periphery of the pumping chamber 230, and a sealing gasket (not shown) is filled between the channels 250 and the sealing plate body 240 for sealing.

Therefore, the displacement motion of the lower pressing body is ensured to be always in the vertical direction, and thus, along with the retraction of the output end of the lifting cylinder, no gap exists between the lower pressing body and the middle frame on the bearing plate body.

Further, the front end of the pressing body 40 exceeds the side end of the bearing plate 20, and the front end of the pressing body does not extend too far to the middle position of the bearing plate, preferably, the front end of the pressing body can just press the edge position of the middle frame on the bearing plate, so that not only the downward moving pressing body can firmly press the middle frame on the surface of the bearing plate, but also the middle position element on the middle frame can not be damaged.

In a further preferred embodiment of the present invention, as shown in fig. 2, a plurality of protruding positioning pins 220 are further disposed on the upper surface of the bearing plate body 20, and the positions of the positioning pins are matched with the positions of the predetermined holes on the surface of the middle frame. The purpose of designing the positioning bolt is to achieve a coarse positioning effect on the middle frame, so that the time for placing the middle frame on the surface of the bearing plate is saved, and the position of the middle frame does not need to be adjusted for two or more times.

In a further preferred embodiment of the present invention, as shown in fig. 3, the bottom of the support frame 10 has an outwardly protruding insertion female body end 110, and a plurality of insertion cylinders 120 arranged around the insertion female body end 110. Therefore, the fixing device special for processing the middle frame can be matched and arranged on the machine table equipment through the matching of the inserting female body end and the inserting column body, so that the applicability of the fixing device special for processing the middle frame is wider.

Obviously, the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention, and it is obvious for those skilled in the art to make other variations or changes based on the above descriptions, and all the embodiments cannot be exhausted here, and all the obvious variations or changes that belong to the technical solutions of the present invention are still in the protection scope of the present invention.
