[0040] Embodiment: A mobile phone back glass assembly equipment comprises a work surface 1, a mobile phone back cover material bin, a carrier 3 for fixing and positioning a mobile phone body, a carrier conveying mechanism 4, a first carrier positioning mechanism 5, a second carrier positioning mechanism 6, a transport module 7 for transporting and assembling a mobile phone back cover, a rolling module 8 and a controller, wherein the carrier conveying mechanism 4 can transport the carrier 3 with the mobile phone body positioned forward, the first carrier positioning mechanism 5 and the second carrier positioning mechanism 6 are arranged on the work surface 1 at intervals along the conveying direction of the carrier conveying mechanism 4, the first carrier positioning mechanism 5 and the second carrier positioning mechanism 6 can respectively fix and position the carrier 3 arriving at the mobile phone back cover assembly station and the mobile phone back cover rolling station, the mobile phone back cover material bin is installed on the work surface 1, and the mobile phone back cover material bin is located on the side of the conveying starting end of the carrier conveying mechanism 4, the mobile phone back cover material bin can store the mobile phone back covers and send the mobile phone back covers 2 one by one to the designated loading position, the transport module 7 can carry the mobile phone back cover at the loading position to the mobile phone body surface positioned on the carrier 3 at the mobile phone back cover assembly station to realize the preliminary assembly of the mobile phone body and the mobile phone back cover. The rolling module 8 includes a rolling fixed seat 81, a rolling bracket 82, a roller 83, and a rolling drive device 84. The rolling fixed seat 81 is fixedly installed on the work table 1, and the rolling fixed seat 81 is located on one side of the second carrier positioning mechanism 6. The rolling bracket 82 is installed on the rolling fixed seat 81. The rolling drive device 84 drives the rolling bracket 82 to reciprocate in the horizontal and vertical directions. At least one roller 83 is installed on the lower side of the rolling bracket 82 and can rotate around a horizontal rotation axis. The roller 83 can roll on the surface of the mobile phone back cover in the carrier 3 positioned on the second carrier positioning mechanism 6. The controller controls the carrier conveying mechanism 4, the first carrier positioning mechanism 5, the second carrier positioning mechanism 6, the transport module 7 and the rolling drive device 84 of the rolling module 8 to start and stop.

[0041] When the equipment is running, the mobile phone body is positioned on the carrier 3. The positioning structure is generally a positioning groove formed on the carrier 3 that matches the shape of the mobile phone body or is realized by a tightening mechanism, a negative pressure suction device, etc., and then the carrier 3 equipped with the mobile phone body is placed on the carrier conveying mechanism 4 and conveyed forward. When the carrier 3 arrives at the mobile phone back cover assembly station, it is fixedly positioned by the first carrier positioning mechanism 5. The carrier 3 cannot continue to be conveyed forward and remains in a stable position without moving. At this time, the mobile phone back cover bin is sent to the specified position by the conveying module 7, and the mobile phone back cover is grabbed and conveyed to the top of the mobile phone body. As the conveying module 7 descends with the mobile phone back cover, the mobile phone back cover is placed on the mobile phone body, and the mobile phone back cover is preliminarily assembled on the mobile phone body through the downward pressure of the conveying module 7. Then the first carrier positioning mechanism 5 cancels the positioning of the carrier 3, and the carrier 3 continues to move forward on the carrier conveying mechanism 4. When the carrier 3 reaches the rolling station of the mobile phone back cover, it is fixed by the second carrier positioning mechanism 6, and the carrier 3 cannot continue to be transported forward and remains in a stable position. The rolling drive device 84 of the rolling module 8 drives the rolling bracket 82 to descend until the roller 83 contacts and presses the surface of the mobile phone back cover on the carrier 3, and then the rolling drive device 84 drives the rolling bracket 82 to move repeatedly along the length direction of the mobile phone back cover, so that the roller 83 rolls back and forth on the surface of the mobile phone back cover, pressing the mobile phone back cover and the mobile phone body to ensure that the two will not separate. The roller 83 rolls and presses the mobile phone back cover without crushing the mobile phone back cover and the mobile phone body, and without leaving marks on its surface, thereby ensuring the aesthetics of the mobile phone back cover. The equipment realizes automatic assembly of mobile phone back covers and avoids manual operation. The controller can also be connected to the Internet to realize intelligent factory management.

[0042] The rolling drive device 84 is a three-axis manipulator or a multi-axis articulated manipulator that moves linearly in three mutually perpendicular directions. The rolling fixed seat 81 is also provided with a horizontal sensing device 85 and a height limiting device 86. The horizontal sensing device 85 can sense the horizontal movement position of the rolling bracket 82 along the rolling direction of the roller 83. The horizontal sensing device 85 is electrically connected and communicated with the controller, and the height limiting device 86 is stopped below the rolling bracket 82 to limit the height of the roller 83 bracket. The horizontal sensing device 85 and the height limiting device 86 limit the range of motion of the roller 83 bracket, thereby preventing the roller 83 from descending too low to damage the mobile phone and the back cover of the mobile phone, and at the same time preventing the roller 83 from rolling too far to crush the corners of the back cover of the mobile phone.

[0043] The rolling bracket 82 is also symmetrically fixed with counterweights 87 on both sides along the rolling direction of the roller 83. The counterweights 87 can increase the pressure-maintaining effect of the roller 83.

[0044] The lower side of the rolling bracket 82 is equipped with a horizontal floating frame 88 that can rotate around a horizontal axis extending parallel to the rolling direction of the roller 83. At least two rollers 83 are symmetrically distributed on both sides of the axis of the horizontal floating frame 88. The outer surface of the circumference of the roller 83 is compounded with an elastic rubber layer. By symmetrically installing the rollers 83 on the horizontal floating frame 88, the rollers 83 can automatically adjust their height when rolling along the back cover of the mobile phone, avoiding interference with the back cover of the mobile phone or uneven pressure at different positions.

The camera 91 can perform frontal imaging of the mobile phone body and the mobile phone back cover in the carrier 3 on the first carrier positioning mechanism 5, and the camera 91 is electrically connected and communicated with the controller. When the transport module 7 assembles the mobile phone back cover to the mobile phone body, the mobile phone body and the mobile phone back cover are illuminated by the light source, and the camera 91 is used to image them. The control system controls the transport module 7 to adjust the position according to the imaging data, thereby ensuring that the assembly position of the mobile phone body and the mobile phone back cover is accurate and avoids misalignment.
