Detailed Description

The following describes specific embodiments of the present utility model in detail with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the utility model, are not intended to limit the utility model.

In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "configured," and "connected" are to be construed broadly, and for example, the term "connected" may be a fixed connection, a removable connection, or an integral connection; either directly or indirectly via an intermediate medium, or in communication with each other or in interaction with each other. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

As shown in fig. 1 to 2, the machine shell magnetic shoe combination station of the specific embodiment of the utility model comprises a tool base 1, a mounting base 2 and a magnetic shoe adsorption device, wherein the mounting base 2 can rotate on the tool base 1, and the rotation of the mounting base 2 can drive the magnetic shoe adsorption device to rotate simultaneously.

Specifically, the adopted magnetic shoe adsorption device comprises a plurality of vacuum adsorption pieces 5 and a centering component 4, wherein the centering component 4 is arranged in the middle of the installation base 2 and penetrates through the center of the installation base 2, namely, the centering component 4 is arranged on one diameter of the installation base 2 at the moment, the vacuum adsorption pieces 5 are arranged on two sides of the centering component 4 so as to be capable of adsorbing magnetic shoes A6 or B7 with different sizes through the vacuum adsorption pieces 5, a boss is further arranged in the middle of the installation base 2, the centering component 4 and the boss are integrally formed, and after the vacuum adsorption pieces 5 adsorb the magnetic shoes, the magnetic shoes with different sizes can be abutted against the boss in a correction state.

In addition, the vacuum absorbing member 5 can have a plurality of absorbing surfaces to a plurality of absorbing surfaces can absorb the magnetic shoe, and because the vacuum absorbing member 5 adopts the vacuum absorbing mode to absorb the magnetic shoe, specifically through setting the middle part of the vacuum absorbing member 5 as the cavity, and set up a plurality of absorption holes on the vacuum absorbing member 5, a plurality of absorption holes communicate the hollow part of the vacuum absorbing member 5, then through the hollow part of continuous suction vacuum absorbing hole, after the magnetic shoe is attached on the absorption hole, air between the magnetic shoe and the absorption hole can be sucked out immediately, thereby make a vacuum space between the vacuum absorbing hole and the magnetic shoe, because the atmospheric pressure in the vacuum space is great in this moment, the atmospheric pressure in the outside space is great, thereby the magnetic shoe can be absorbed on the vacuum absorbing member 5 by the stability to the magnetic shoe from the outside, and adopt the vacuum absorbing mode can avoid absorbing the magnetism tiny particle in the operational environment, thereby avoid the magnetic particle in the operational environment to receive in the process of being absorbed and corrected, thereby the abrasion of the magnetic particle in the operational environment is caused by the magnetic shoe.

More specifically, as shown in fig. 3, the vacuum suction member 5 is provided with a gap from the centering assembly 4 in an initial state, and the vacuum suction member 5 is adapted to abut against both sides of the centering assembly 4 to enable centering correction of the magnetic shoe provided thereon. When the magnetic shoe is absorbed on the vacuum absorbing member 5, because the size of the vacuum absorbing member 5 is larger, the size of the magnetic shoe is relatively smaller than the size of the vacuum absorbing member 5, therefore, when the magnetic shoe is absorbed at the middle position of the vacuum absorbing member 5, the magnetic shoe is possibly biased to the left part, the right part, the upper part or the lower part of the vacuum absorbing member 5, namely, the position of the magnetic shoe cannot be positioned at a set position, therefore, after the magnetic shoe is installed in a shell without correcting the position of the magnetic shoe, the magnetic shoe and the shell are likely to be in line with the position requirement of assembly, and therefore, the formed product yield is reduced, and therefore, the magnetic shoe position absorbed on the vacuum absorbing member 5 needs to be corrected, and because the vacuum absorbing member 5 is possibly positioned between the vacuum absorbing member 4 in an initial state, namely, the vacuum absorbing member 5 is not contacted with the middle component 4, and the gap between the vacuum absorbing member 5 and the middle component 4 at the two sides is equal to each other, and the vacuum absorbing member 5 at the two sides can be compressed to the left side of the vacuum absorbing member 4 by the vacuum absorbing member 4, and the vacuum absorbing member 4 can not be compressed to the left side of the middle component 4, and the vacuum absorbing member 4 can be completely compressed to the position of the vacuum absorbing member 4 at the two sides, and the vacuum absorbing member 4 can not be completely compressed to the middle position of the vacuum absorbing member 4 at the two sides.

Specifically, the middle part of the centering component 4 is hollowed out to form an arch structure, namely, when the centering correction is performed, two sides of the vacuum adsorption piece 5 are only propped against two sides of the centering component 4, and similarly, the magnetic shoe is also only propped against two sides of the centering component 4.

More specifically, the vacuum absorbing members 5 arranged at two sides of the centering assembly 4 are connected through the springs 8, the springs 8 are arranged in the mounting base 2, the springs 8 are suitable for penetrating through the centering assembly 4, when centering operation is needed, centering can be achieved through the compression springs 8, the compression springs 8 can be achieved through the corresponding abutting members 3, the abutting members 3 are arranged in the tool base 1, due to the fact that the inside of the tool base 1 is hollow, the abutting members 3 can freely move in the tool base 1, the abutting members 3 are arranged corresponding to the vacuum absorbing members 5, the abutting members 3 are arranged at two sides of the springs 8, the springs 8 can be synchronously driven to compress through the compression of the compression abutting members 3, the compression of the springs 8 drives the vacuum absorbing members 5 to perform centering, and centering correction operation on magnetic tiles is finally achieved.

In addition, in order to facilitate the compression of the abutting piece 3, the abutting piece 3 partially protrudes out of the tool base 1, so that the centering and pressing operation of the abutting piece 3 can be realized only by compressing the protruding portion.

As shown in fig. 1, the mounting base 2 is further provided with a positioning protrusion 21, and the positioning protrusion 21 is arranged along the radial direction of the mounting base 2, and because the adopted casing is provided with a groove which can be matched with the positioning protrusion 21, the positioning protrusion 21 can be clamped with the groove on the casing for facilitating the mounting of the casing, and at this time, after the casing is arranged on the mounting base 2, the positioning protrusion 21 can be positioned at the position of the casing, so that the accuracy of the position of the casing after the mounting is ensured.
