[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] like Figure 1-7 As shown, a high-speed precision assembly line for windshield clip strips described in the present invention comprises a high-speed transmission mechanism 1, a turning mechanism 3, a shuttle mechanism 4, a short-side positioning mechanism 5, a trapezoidal positioning mechanism and a suction mechanism 7; the transmission mechanism 1 is used for loading and unloading materials. During loading, the windshield 2 is transported to the turning mechanism 3, the turning mechanism 3 turns the windshield 2 over, the shuttle mechanism 4 transports the turned windshield 2 to the clip strip assembly position, the short-side positioning mechanism 5 and the trapezoidal positioning mechanism cooperate with the windshield 2, and the suction mechanism 7 adsorbs the windshield 2 to fix the windshield 2.

[0030] The high-speed transmission mechanism 1 comprises a transmission frame 201 , on which a transmission reduction motor and two high-speed belts 202 are arranged. The transmission reduction motor drives the two high-speed belts 202 to transmit synchronously.

[0031] The high-speed transmission mechanism 1 quickly delivers the windshield 2 to the center position of the flip, calculates the travel distance through the encoder, and the glass stops when the center position distance is obtained. At this time, the windshield 2 is in a posture with the concave surface facing upward.

[0032] The flipping mechanism 3 includes a lifting gantry 101, on which a lifting drive mechanism 102 and a flip lifting platform 103 are arranged. The lifting drive mechanism 102 is a reduction motor cooperated with double-sided transmission shafts. Both sides of the lifting gantry 101 are provided with screw lifting transmission pairs. The double-sided transmission shafts of the reduction motor drive the screws on both sides of the gantry to rotate through structures such as bevel gears. The screws on both sides cooperate with their respective flip lifting platforms 103 to drive the lifting and lowering of the flip lifting platform 103. A flip motor 104 and a flip connecting rod 105 are arranged on the flip lifting platform 103. The flip motor 104 drives the flip connecting rod 105 to rotate. A suction cup flip adjustment seat 106 is arranged on the flip connecting rod 105. Flip suction cups 107 are arranged on both ends of the suction cup flip adjustment seat 106. The flip suction cups 107 at both ends can adjust the spacing and angle to match glass of different models, arc surfaces and sizes.

[0033] When performing the flipping action, the flip suction cup 107 first absorbs the windshield 2 on the high-speed transmission mechanism 1 from the bottom surface, and the flip lifting platforms 103 on both sides of the gantry 101 rise synchronously. After reaching a certain height, the flip motors 104 on the flip lifting platforms 103 on both sides act synchronously, and drive the windshield 2 to rotate and flip through the flip connecting rod 105 and the suction cup flip adjustment seat 106, so that the windshield 2 is in a concave downward posture, and then descends.

[0034] The shuttle mechanism 4 includes a shuttle rail 203, a shuttle slide 204 and a shuttle driving component. The shuttle rail 203 is located between two high-speed belts 202. The shuttle rail 203 is parallel to the high-speed belt 202 and shares a common frame. The shuttle slide 204 slides in cooperation with the shuttle rail 203. The shuttle slide 204 is provided with a shuttle lifting cylinder 205 and a shuttle lifting platform 206. The shuttle lifting platform 206 is provided with a shuttle suction cup frame 207 and a flexible rotation driving motor 208. The shuttle suction cup frame 207 is rotatably arranged on the shuttle lifting platform 206. The shuttle suction cup frame 207 is provided with a shuttle suction cup 209 and a flexible limiting top block. The flexible rotation driving motor 208 drives the shuttle suction cup frame 207 to rotate, so that the windshield 2 on the shuttle can be rotated to a certain angle.

[0035] After the windshield 2 is flipped down, the shuttle lifting cylinder 205 drives the shuttle lifting platform 206 to rise, so that the shuttle suction cup 209 adsorbs the middle position of the windshield 2 from the bottom surface, and at the same time the flip suction cup 107 is released, the windshield 2 is fixed on the shuttle mechanism 4, and the shuttle mechanism 4 can drive the windshield 2 to move to the card strip assembly position.

[0036] The short side positioning mechanism 5 includes a short side positioning slide 301, which is located on the upper side of the shuttle mechanism. Two groups of short board lifting guide frames 302 are arranged on the short side positioning slide 301. The two groups of short board lifting guide frames 302 are driven by a short side positioning motor 303 respectively, and move synchronously in the same direction or in the opposite direction along the positioning slide 301; a short side positioning cylinder 304 and a cone head positioning rod 305 are arranged on the short board lifting guide frame 302. The short board lifting guide frame 302 has a lifting guide structure. The short side positioning cylinder 304 controls the cone head positioning rod 305 to lift and lower along the lifting guide structure. After the windshield 2 is moved into place by the shuttle, the short side positioning motor 303 drives the two groups of short board lifting guide frames 302 to move a certain distance to the middle, and the two cone head positioning rods 305 descend and press against the two short sides of the windshield 2 from the upper side.

[0037] The cone head of the cone head positioning rod is divided into a conical polyurethane sleeve wear part, which can be replaced as needed. The conical polyurethane sleeve is a wear-resistant hollow material. After processing, it can be nested with the positioning rod. The angle of the cone head is adjustable so that it is parallel to the normal of the profile on both sides of the short side of the glass, thereby ensuring the positioning accuracy of the glass.

[0038] The trapezoidal positioning mechanism comprises four groups of trapezoidal positioning components 6, of which two groups of trapezoidal positioning components 6 are arranged on one side of the shuttle mechanism 4 and are parallel to each other, and the other two groups of trapezoidal positioning components 6 are obliquely arranged on the other side of the shuttle mechanism 4; a trapezoidal positioning skeleton 61 is arranged on one side of the shuttle mechanism 4, and two groups of mutually parallel trapezoidal positioning components 6 are arranged on the trapezoidal positioning skeleton 61, and two oblique trapezoidal positioning seats 62 are arranged on the other side of the shuttle mechanism 4, and a group of trapezoidal positioning components 6 are respectively arranged on the two trapezoidal positioning seats 62, and the oblique angles of the two trapezoidal positioning seats 62 are adjustable; the trapezoidal positioning mechanism comprises four groups of trapezoidal positioning components 6, of which two groups of trapezoidal positioning components 6 are arranged on one side of the shuttle mechanism 4 and are parallel to each other, and the other two groups of trapezoidal positioning components 6 are obliquely arranged on the other side of the shuttle mechanism 4; The trapezoidal positioning assembly 6 includes a trapezoidal positioning slide 401, a trapezoidal positioning moving seat 402 is arranged on the trapezoidal positioning sliding table 401, a sleeve cylinder assembly 403 and a supporting positioning rod 404 are arranged on the trapezoidal positioning moving seat 402, the sleeve cylinder assembly 403 drives the supporting positioning rod 404 to rise and fall, and the connecting line of the supporting positioning rods 404 of the four groups of trapezoidal positioning assemblies 6 is trapezoidal, and the four supporting positioning rods 404 cooperate with the four corners of the windshield; the distribution of the trapezoidal structure meets the mutual consistency with the shape of the glass, is conducive to positioning, and has strong adaptability, and can perform positioning operations according to different glass shapes.

[0039] A group of suction mechanisms 7 are respectively arranged on both sides of the shuttle mechanism 4, and the suction mechanisms 7 include a suction lifting cylinder 501, a suction lifting frame 502, a suction guide plate 503 and a suction adjustment frame 504. The suction lifting cylinder 501 and the suction guide plate 503 are fixed, and the suction lifting frame 502 and the suction guide plate 503 are slidably matched. The suction lifting cylinder 501 drives the suction lifting frame 502 to rise and fall, and the suction adjustment frame 504 is arranged on the suction lifting frame 502. Waist-shaped suction cups 505 are arranged on both ends of the suction adjustment frame 504. The waist-shaped suction cups 505 have a certain degree of rotational freedom on the suction adjustment frame 504, so that they can be easily adjusted to adapt to the outer surface of the convex surface of the glass. The adaptation is achieved by a floating joint between the suction cup and the adjustment block to achieve an angle that matches the convex surface of the glass.

[0040] After the positioning and holding actions are completed, the external mechanism can assemble the windshield strips. After completion, the mechanisms are released to allow the glass to fall into the high-speed conveying mechanism for unloading.
