[0033] Reference Figure 1 The present invention provides a double-sided processing device for a mobile phone back cover, comprising: a rotating table 1, a first column 2, a second column 3, a first fixing component 4, a second fixing component 5, a first processing mechanism 6, a second processing mechanism 7, and a main driving mechanism.

[0034] The main driving mechanism is connected to the rotating table 1 to drive the rotating table 1 to rotate, and the first column 2 is vertically fixed on the rotating table 1 to rotate along with the rotation of the rotating table 1. The first column 2 is provided with a first slide 8 and a first driving mechanism for driving the slide to move up and down on the first column 2. The first fixing component 4 is installed on the first slide 8 to move up and down along with the up and down movement of the first slide 8. The first fixing component 4 includes a first fixing mechanism 41 for fixing the back cover of the mobile phone and keeping the convex surface of the fixed mobile phone back cover facing upward, and a first flipping mechanism 42 for driving the first fixing mechanism 41 to flip.

[0035] The second column 3 is vertically fixed on the outer side of the rotating platform 1. The second column 3 is provided with a second slide 8 and a second driving mechanism for driving the second slide 8 to slide up and down on the second column 3. The second fixing assembly 5 is installed on the second slide 8 to move up and down with the up and down movement of the second slide 8. The second fixing assembly 5 includes a second fixing mechanism 51 for fixing the back cover of the mobile phone and keeping the back cover of the mobile phone fixed with the concave surface facing upward and a second flipping mechanism 52 for driving the second fixing mechanism 51 to flip. The first fixing mechanism 41 and the second fixing mechanism 51 fix the back cover of the mobile phone by clamping or vacuum adsorption.

[0036] The first processing mechanism 6 is located above the first fixing mechanism 41 to process the convex surface of the back cover of the mobile phone. The second processing mechanism 7 is located above the second fixing mechanism 51 to process the concave surface of the back cover of the mobile phone. The specific working method is as follows:

[0037] First, the first processing mechanism 6 processes the convex surface of the mobile phone back cover fixed by the first fixing mechanism 41; when the convex surface of the mobile phone back cover is processed, the main driving mechanism drives the rotating table 1 to rotate, so as to drive the first fixing mechanism 41 to rotate to the top of the second fixing mechanism; when the first fixing mechanism 41 enters the top of the second fixing mechanism 51, the first fixing mechanism 41 flips downward, and then the first fixing mechanism 41 moves downward or the second fixing mechanism 51 moves upward, so that the two are in the closest position state, at this time, the first fixing mechanism 41 releases the fixation on the mobile phone back cover, and the second fixing mechanism 51 fixes the mobile phone back cover, and the mobile phone back cover is switched from the convex surface facing up to the concave surface facing up; then, the rotating table 1 drives the first column 2 to rotate and reset, and the second processing mechanism 7 enters the processing state to complete the processing of the concave surface of the mobile phone back cover.

[0038] As can be seen from the above, in the present invention, the first column 2 can rotate with the rotation of the rotating seat; the first fixing component 4 can move up and down on the first column 2; the second fixing component 5 can move up and down on the second column 3; the first processing mechanism 6 is arranged above the first fixing mechanism 41 to process the convex surface of the back cover of the mobile phone. When the convex surface of the back cover of the mobile phone is processed, the rotating table 1 rotates to drive the first fixing component 4 to rotate to the top of the second fixing component 5. At this time, the first fixing mechanism 41 in the first fixing component 4 is flipped downward to a relative state with the second fixing mechanism 51, and the first fixing mechanism 41 is moved down or the second fixing mechanism 51 is moved up, so that the two enter the closest position state. At this time, the first fixing mechanism 41 releases the fixation of the back cover of the mobile phone, and the second fixing mechanism 51 fixes the back cover of the mobile phone, and the back cover of the mobile phone is switched from the convex surface facing up to the concave surface facing up. Then, the rotating table 1 drives the first column 2 to rotate and reset, and the second processing mechanism 7 can process the concave surface of the back cover of the mobile phone. The design of this structure realizes the automation of double-sided processing of the mobile phone back cover, effectively improving the processing efficiency of the mobile phone back cover.

[0039] Furthermore, a double-sided processing device for the back cover of a mobile phone proposed in the present invention also includes a first conveyor line 10 and a second conveyor line 11 for transmitting the back cover of the mobile phone, wherein: the output end of the first conveyor line 10 passes through the bottom of the first fixing mechanism 41, and when loading, the first fixing mechanism 41 flips downward and moves downward to grab the workpiece from the first conveyor line 10 to complete the automatic loading action. After grabbing the workpiece, the first fixing mechanism 41 flips upward and moves upward to reset, so as to bring the workpiece into the convex processing station.

[0040] The second conveyor line 11 passes under the second fixing mechanism 51. When unloading, the second fixing mechanism 51 flips and moves downward to transfer the mobile phone back cover that has completed the concave surface processing to the second conveyor line 11, and the second conveyor line 11 transfers the mobile phone back cover that has completed the double-sided processing to the next station.

[0041] Furthermore, the first conveyor line 10 includes a plurality of carriers and a first power mechanism that drives the carriers to circulate in sequence and passes through the bottom of the first fixing mechanism 41. Each carrier is provided with a positioning groove for placing the back cover of the mobile phone, so as to facilitate the first fixing mechanism 41 to accurately grasp the workpiece. The second conveyor line 11 includes a conveyor belt and a second power mechanism that drives the conveyor belt to circulate and rotate under the second fixing mechanism 51.

[0042] In this embodiment, the first fixing mechanism 41 and the second fixing mechanism 51 fix the back cover of the mobile phone in at least three ways:

[0043] The first one: reference Figure 2 The first fixing mechanism 41 includes a vacuum adsorption fixture having a vacuum adsorption convex surface 411. The shape of the vacuum adsorption convex surface 411 is adapted to the concave surface of the mobile phone cover plate, so that the concave surface of the mobile phone back cover can be buckled on it, thereby supporting the mobile phone back cover from the concave surface direction of the mobile phone back cover, so that the convex surface of the mobile phone back cover faces upward. The vacuum adsorption convex surface 411 is provided with a vacuum suction hole A to fix the mobile phone back cover by vacuum adsorption.

[0044] Reference Figure 3 The second fixing mechanism 51 also includes a vacuum adsorption fixture. The vacuum adsorption fixture in the second fixing mechanism 51 has a vacuum adsorption concave surface 511. The shape of the vacuum adsorption concave surface 511 matches the convex surface of the mobile phone back cover so that the convex surface of the mobile phone cover plate can be accommodated, thereby supporting the mobile phone back cover from the convex surface direction of the mobile phone back cover so that the concave surface of the mobile phone back cover faces upward. A vacuum suction hole B is provided on the vacuum adsorption concave surface 511 to fix the mobile phone back cover by vacuum adsorption.

[0045] The second type: reference Figure 4 The first fixing mechanism 41 includes an inner support seat 412 on which the concave surface of the back cover of the mobile phone can be buckled, an airbag A413 arranged on the side wall of the inner support seat 412, and a first control mechanism for controlling the inflation / deflation of the airbag A413. When working, when the concave surface of the back cover of the mobile phone is buckled onto the inner support seat 412, the first control mechanism controls the inflation of the airbag A413 to expand the airbag A413 to achieve the purpose of clamping and fixing the back cover of the mobile phone. When the airbag A413 is deflated, the support seat automatically releases the fixation of the back cover of the mobile phone.

[0046] Reference Figure 5The second fixing mechanism 51 includes a receiving groove 512 for the convex surface of the back cover of the mobile phone to enter, an airbag B513 arranged on the side wall of the receiving groove 512, and a second control mechanism for controlling the inflation / deflation of the airbag B513. Similarly, when the convex surface of the back cover of the mobile phone enters the receiving groove 512, the second control mechanism controls the inflation of the airbag B513 to make the airbag B513 expand and squeeze the outer periphery of the back cover of the mobile phone, thereby achieving the purpose of clamping and fixing the back cover of the mobile phone. When the airbag B513 is deflated, the back cover of the mobile phone loses the constraint of the airbag B513 and enters a loosened state.

[0047] Furthermore, in this embodiment, the side wall of the support seat is provided with a plurality of inner grooves arranged in a circumferential direction, each inner groove is provided with a corresponding airbag A413, each airbag A413 is respectively connected to the first control mechanism to be controlled by the first control mechanism to be uniformly inflated / deflated, when the airbag A413 is inflated, it protrudes from the inner groove where it is located to tightly press against the inner wall of the mobile phone back cover, when the airbag A413 is deflated, the airbag A413 is separated from the mobile phone back cover and retracted into the inner groove where it is located, thereby loosening the fixation of the mobile phone back cover. In addition, the inner groove can also be changed into an annular groove, and the airbag A413 can be changed into an annular airbag.

[0048] The side wall of the receiving groove 512 is provided with a plurality of inner grooves in the circumferential direction, and a corresponding airbag B513 is provided in each inner groove. Each airbag B513 is respectively connected to the second control mechanism so as to be controlled by the second control mechanism to be uniformly inflated / deflated. When the airbag B513 is inflated, it protrudes from the inner groove where it is located to tightly press against the outer wall of the back cover of the mobile phone. When the airbag B513 is deflated, the airbag B513 is separated from the back cover of the mobile phone and retracted into the inner groove where it is located, thereby loosening the fixation of the back cover of the mobile phone. In addition, the inner groove on the receiving groove 512 can also be changed to an annular groove, and the airbag B513 can be changed to an annular airbag accordingly.

[0049] The third type: the first fixing mechanism 41 includes a base plate, and a support base and a clamping member installed on the base plate; the support base has a supporting surface for the concave surface of the back cover of the mobile phone to be buckled onto; there are at least two clamping members, which are circumferentially distributed on the periphery of the support base, and the clamping member includes a clamping block and a power component that drives the clamping block to move toward the support base; when working, the back cover of the mobile phone is buckled on the support base, and the clamping members arranged on the periphery of the support base respectively press against the outer wall of the back cover of the mobile phone from the periphery of the back cover of the mobile phone to achieve clamping and fixing of the back cover of the mobile phone.

[0050] Similarly, the second fixing mechanism 51 includes a base and a clamping member installed on the base. There are at least two clamping members and they are distributed circumferentially. The clamping member includes a clamping block and a power component that drives the clamping block to move toward the central part of the distribution. When the back cover of the mobile phone enters the inner side of each clamping member, the clamping blocks in each clamping member move toward the back cover of the mobile phone at the same time to achieve clamping and fixing of the back cover of the mobile phone.

[0051] Furthermore, a positioning groove is provided on the base and at the center of each clamping member, and the shape of the positioning groove is adapted to the convex surface of the back cover of the mobile phone, so that the placement position of the back cover of the mobile phone can be positioned through the positioning groove.

[0052] In addition, the first processing mechanism 6 in this embodiment includes a first processing head and a first power component for driving the first processing head to perform processing actions; the second processing mechanism 7 includes a second processing head and a second power component for driving the second processing head to perform processing actions.
