DETAILED DESCRIPTION

[0015] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0016] Example 1 like Figures 1-3 As shown, a positioning mechanism for double-sided synchronous alignment of patterns and plates in a transverse press comprises a hydraulic lifting platform 24, a rotary lifting platform 22 is provided above the hydraulic lifting platform 24, a slide rail Y-axis lateral movement platform 23 and a slide rail X-axis lateral movement platform 20 are provided above the rotary lifting platform 22, and no less than two synchronous wheel conveyor belts 19 are provided on the slide rail X-axis lateral movement platform 20, and a clamping plate A9, a clamping plate B10, a clamping plate C11 and a clamping plate D12 are provided on both sides of the hydraulic lifting platform 24, which are respectively The splint cylinder A13, splint cylinder B14, splint cylinder C15 and splint cylinder D16 control tightening and opening. A board feed servo motor 25 is provided on the outside of the hydraulic lifting platform 24. The board feed servo motor 25 transmits power to the board feed transmission mechanism 26. The board feed servo motor 25 is connected to the board feed transmission mechanism 26 through a synchronous pulley. The top of the hydraulic lifting platform 24 is provided with a camera A1 and a camera B2 with visual processing software, and is electrically connected to the PLC. The PLC controls the power system.

[0017] The rotary lifting platform 22 is rotated by a rotary servo motor 21 connected thereto.

[0018] The synchronous wheel conveyor belt 19 is used to ensure the advancement accuracy of the decorative panel.

[0019] The X-axis servo electric cylinder 17 and the Y-axis servo electric cylinder 18 respectively control the movement of the slide rail Y-axis lateral movement platform 23 and the slide rail X-axis lateral movement platform 20 through screws.

[0020] The moving distances of the clamping plate A9, the clamping plate B10, the clamping plate C11 and the clamping plate D12 are controlled by the clamping plate servo electric cylinder A3, the clamping plate servo electric cylinder B4, the clamping plate servo electric cylinder C5 and the clamping plate servo electric cylinder D6 respectively.

[0021] The hydraulic lifting platform 24 realizes its displacement and rotation by rotating the lifting platform 22, the slide rail Y-axis lateral movement platform 23 and the slide rail X-axis lateral movement platform 20, so as to adjust the gap between the set coordinates and the actual coordinates.

[0022] The lifting servo cylinder A7 and the lifting servo cylinder B8 push the side panels connected to their respective output shafts respectively. An L-shaped block is provided at the bottom of the side panels. The movement of the side panels drives the block to be clamped in and out of the bottom of the board feed elevator A27 and the board feed elevator B28 on the same side to control the lifting.

[0023] Working process: After the hydraulic lifting platform 24 is lifted to the set height, the camera A1 and the camera B2 take pictures to pick up the coordinates of the two MARK points on the decorative paper, and send them to the visual processing software. The software compares the set coordinates with the actual coordinates, calculates the deviation value, and sends it to the PLC communication. The PLC sends a signal to control the X-axis servo cylinder 17 and the Y-axis servo cylinder 18 to control the sliding rail X-axis horizontal moving platform 20 and the sliding rail Y-axis horizontal moving platform 23 respectively through the screw rod to realize the front and back and left and right movement of the hydraulic lifting platform 24. The hydraulic lifting platform 24 also has a rotating mechanism at the bottom, which realizes rotation through the rotating servo motor 21. The hydraulic lifting platform 24 moves forward, backward, left and right and rotates to make the actual coordinates of the MARK point consistent with the set coordinates. After 2-3 times of photographing and comparison, the above actions are repeated until the coordinates are completely consistent. After obtaining the position of the decorative paper and the base plate according to the MARK point coordinates, the clamping plate servo cylinder A3, the clamping plate servo cylinder B4, the clamping plate servo cylinder C5 and the clamping plate servo cylinder D6 control the clamping plate A9, the clamping plate B10, the clamping plate C11 and the clamping plate D12 to move a set distance respectively, and then the clamping plate cylinder A13, the clamping plate cylinder B14, the clamping plate cylinder C15 and the clamping plate cylinder D16 accurately clamp the four positions on both sides of the decorative plate to avoid clamping the decorative paper too much or too little. After clamping the decorative paper, it is pasted with the base plate and lowered through the hydraulic lifting platform 24. The forward servo motor 25 is driven to move forward, and the synchronous wheel conveyor belt 19 ensures the forward precision of the decorative plate. Because the MARK point of the decorative paper has been moved to the set coordinates, the MARK point coordinates of the steel plate in the press are known, the visual processing software calculates the distance that the decorative paper needs to move and communicates with the PLC, the PLC sends a signal to the forward servo motor 25 to move the calculated distance, and after reaching the position, the clamping plate cylinder A13, the clamping plate cylinder B14, the clamping plate cylinder C15 and the clamping plate cylinder D16 release the clamp, the clamping plate servo cylinder A3, the clamping plate servo cylinder B4, the clamping plate servo cylinder C5 and the clamping plate servo cylinder D6 control the clamping plate A9, the clamping plate B10, the clamping plate C11 and the clamping plate D12 to reset respectively, and at the same time the decorative paper and the base plate fall into the press, and the press is closed to press and paste; During the feeding process, the lifting servo cylinder A7 and the lifting servo cylinder B8 control the plate feeding elevator A27 and the plate feeding elevator B28 to descend to a set distance respectively to avoid displacement and paper breakage of the decorative paper and the base plate during the falling process due to excessive height.
