[0036] In this embodiment, the reversing mechanism is a mechanism driven by a servo motor to rotate, such as a servo motor in conjunction with a cam cutter, which is a prior art and will not be described in detail, and other structures are also possible as long as they can realize the function of driving the mounting seat to rotate.

[0044] A rotary reversing mechanism 4, used for reversing the mounting seat and the mechanism fixed on the mounting seat during the pressing process;

[0045] Positioning detection camera 7, used to take pictures to determine the position of the product before and after lamination and record the current data in real time;

[0046] Roller 221, used for pressing products, such as pressing a laptop screen (LCD) into a frame;

[0049] Pressure sensor, used to monitor the pressure during pressing;

[0050] Working principle or process:

[0051] The pressing module can be equipped with an automatic power source (for example, installed at the end of a robotic arm). When the product needs to be pressed, the pressing module can be started to drive the mechanism below the pressing module to move along the Z-axis direction; when the product needs to be pressed in the X-axis direction, the rotary reversing mechanism can be stationary in the X-axis direction, the positioning detection camera will take pictures of the feeding, and the pitch-changing mechanism will automatically adjust the position, that is, the positions of the two pressing mechanisms are adjusted to correspond to the pressing positions of the products; the pressing module drives the mechanism below the pressing module to move along the Z-axis direction, the roller presses the product, and the pressing buffer structure performs buffering. The buffer mechanism uses elastic parts (such as springs). When pressed to a certain position, the pressure sensor will send a signal to limit the position, and the pressing in the X-axis direction is completed; the positioning detection camera will record the data after pressing;

[0052] The above is the working principle of X-axis pressing. When the product needs Y-axis pressing, the rotary reversing mechanism will drive the mounting seat to rotate 90° in the Y-axis direction, and the subsequent pressing steps are the same as those of the X-axis.

[0053] This device can identify the position and angle of the product by a positioning detection camera, and then automatically adjust the spacing between the rollers according to the product model. This device can cooperate with the assembly line to achieve online pressing with high pressing efficiency.

[0054] The above description is only an embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the specification and drawings of the present utility model, or directly or indirectly used in other related technical fields, is also included in the patent protection scope of the present utility model.
