The vertical flip limiting mechanism adopts integral design of hydraulic buffer 22062, limiting screw 22061 and limiting detection sensor 22064, and the vertical flip mechanism is slowed down by hydraulic buffer when it is flipped, and the limiting screw is accurately positioned to ensure that the mechanism stops smoothly, which has a protective effect on the equipment and products. The limiting mounting block 2205 is installed and fixed on the vertical flip hollow shaft 2203 through the limiting block positioning key 22053 and the screw on the limiting positioning hole 22052. When the vertical flip mechanism drives the vertical flip hollow shaft 2203 to flip, the limiting block 2205 flips until it hits the limiting buffer 22062 to slow down and then hits the limiting screw 1-22061. At this time, the limiting detection screw 22051 installed on the limiting block 2205 enters the detection area of the limiting detection sensor 22064, and the sensor transmits a signal to the PLC to execute brake and locking action.

The left locking block 2208 is fixed to the limit mounting block 2205 and rotates with the vertical tilt hollow shaft 2203. When the vertical tilt mechanism 2 rotates, the limit mounting block 2205 rotates via the vertical tilt hollow shaft 2203. When the limit detection sensor 22064 detects the position, the locking cylinder 22072 of the locking mechanism 2207 extends, driving the locking pin 22073 within the locking guide block 22077 and locking it in the right locking block 22074. To rotate 180 degrees to the other side, first release the brake mechanism 2204 and locking mechanism 2207.

[0047] like Figure 8 As shown: This is a three-dimensional structural diagram of the suction cup and the tooling plate. The back of the glass 5 is installed on the tooling plate 4 through the suction cup 33.

[0049] The utility model also provides a primer coating method, comprising the following steps:

[0050] Move the original glass with the front side facing up to the tooling changing plate with 4 suction cups. When placing the glass, there are guide blocks on the back, left and right to center the glass. Scan the QR code engraved on the glass and record the barcode information.

[0051] Press the foot switch, 4 suction cups open the vacuum and suck the back of the glass to prevent the front of the glass from being scratched, when the negative pressure reaches the set value, the locking device and the brake device of the vertical turning mechanism are released. Press the right turning handle, the vertical turning mechanism turns clockwise on the vertical plane. When the turning is close to 180 degrees, the vertical turning limiting mechanism is touched, the limiting buffer slows down the turning mechanism until it stops by touching the limiting screw. At this time, the limiting detection sensor detects that the vertical turning mechanism is turned to the position, the vertical turning brake mechanism cylinder acts, the brake pad brakes the hollow shaft brake disc, and the turning locking mechanism cylinder extends to lock.

[0052] Take the cleaning paper with the cleaning agent and place it on the annular area of the glass with the back facing up, at this time the rotation locking device of the horizontal rotation mechanism is released. Operate the rotation handle to rotate counterclockwise, and the cleaning paper cleans the glass for one turn. During rotation, the rotation detection device counts to confirm one turn to prevent errors, and the cleaning paper is thrown into the hazardous waste barrel after cleaning is completed, and detection is prevented. Then take the primer bottle on the electronic scale, invert the primer bottle, and press the primer outflow head to the annular glass area that has just been cleaned, rotate for one turn, and the rotation detection device counts to confirm one turn to prevent errors, and the coating area 6 is as shown in the shadow part. Figure 9 The horizontal rotation device returns to the original position. At this time, the glass bead locking device preliminarily positions the horizontal rotation mechanism, the primer bottle is placed on the electronic scale again, and the primer usage is calculated.

[0053] Press the button to confirm, the rotation detection device detects that the horizontal rotation mechanism is in the original position, the rotation locking device performs the locking action, and the primer detection sensor confirms whether there is coating. If the coating is detected and the weight calculation is qualified, the brake and locking device of the vertical turning mechanism are released; if no coating is detected or the weight calculation is unqualified, the vertical turning mechanism is locked and an alarm is given. At this time, press the left turning handle, the vertical turning mechanism turns counterclockwise on the vertical plane to make the front of the glass face up. When the reverse turning is close to 180 degrees, it returns to the original position, touches the vertical turning limiting mechanism, and the limiting buffer slows down the turning mechanism until it stops by touching the limiting screw. At this time, the limiting detection sensor detects that the vertical turning mechanism is turned to the original position, the vertical turning brake mechanism cylinder acts, the brake pad brakes the hollow shaft brake disc, and the turning locking mechanism cylinder extends to lock.

[0054] The vacuum is released, the bar code is printed on the glass, and then the glass is taken out. The collected bar code information and the primer coating usage are recorded and saved to the database, and the entire coating and detection process is completed.

[0055] The advantages of the utility model lie in:

[0056] The employee can conveniently operate and check the front and back of the glass, and ensure the comprehensiveness and accuracy of coating and quality checking. The device also integrates a horizontal rotating mechanism, so that the employee can more conveniently access to each edge of the glass to perform primer coating and checking. A pneumatic slip ring is adopted to truly realize the rotation of the mechanism without causing air pipe winding. By using bearings and rotary supports, the operator only needs to overcome small force to achieve the purpose of labor saving during overturning and rotating. The vertical overturning brake mechanism can be braked in emergency, thereby ensuring the safety of the operator and the maintenance personnel. The locking mechanisms of the vertical overturning guard and the horizontal rotating mechanism both adopt inclined concave-convex and guide block structures, so as to facilitate alignment and positioning, and the movement is not stuck. The rotating locking device adopts an inclined concave-convex structure combined with a glass bead locking device, so as to facilitate alignment and positioning, and the T-shaped bolt structure can prevent the mechanical parts from being stuck due to machining and assembly problems.

[0057] In summary, the utility model provides a kind of automobile sunroof glass edge processing equipment of integrated vertical overturning and horizontal rotating mechanism. The device improves the work efficiency of employee and the accuracy of operation by providing convenient operation mode and multifunctional integration. Meanwhile, the integrated waste gas treatment, primer weighing, glass scanning code, bar code mistake proofing and data tracing functions further improve production efficiency, coating quality, compatible multiple glass flexible production, reduce labor cost, improve work environment safety and product management level.
