Description

[0045] Before use, the suction end of the suction pump needs to be connected to the suction disc 6. When the electric telescopic rod 5 is located at the feeding station 300, the electric telescopic rod 5 is driven to extend, so that the suction disc 6 is pressed against the top center position of the sunroof glass. At the same time, the suction pump is driven to suck, so that the suction disc 6 forms a negative pressure to adsorb the sunroof glass. After the adsorption is completed, the electric telescopic rod 5 is retracted to reset. Then, the motor 3 is driven to rotate, so as to drive the sunroof glass to move to the placing and taking-out station 100.

Then, the electric telescopic rod 5 is reset, the linear motor 43 drives the extension rod 42 to reset, and then the injection molding equipment performs the edge injection molding work. After the injection molding is completed, the upper and lower molds are separated, and then the sunroof glass is taken out by cooperation of the linear motor 43, the electric telescopic rod 5 and the suction disc 6. Then, the sunroof glass is conveyed to the discharging station 200 for discharging, and the edge injection molding work of the sunroof glass is completed.

[0047] The plasma cleaning assembly 8 comprises a first support 81 and a plasma cleaning head 82. The top of one of the moving blocks 712 above the base 1 is fixed with the first support 81. The upper end of the first support 81 is relatively fixed with two plasma cleaning heads 82, and the cleaning ends of the two plasma cleaning heads 82 are opposite to each other. The plasma cleaning head 82 is longitudinally arranged. The plasma cleaning head 82 is a prior art, and thus will not be described here. The plasma cleaning head 82 is used to clean the periphery of the sunroof glass.

[0048] The affinity agent primer assembly 9 comprises a second support 91 and a nozzle 92, the top of a moving block 712 above the base 1 is fixed with the second support 91, the upper end of the second support 91 is relatively fixed with two nozzles 92, and the discharge ends of the two nozzles 92 correspond to each other. The nozzle 92 is longitudinally arranged. Before the equipment works, the output end of the affinity agent conveying equipment is connected with the two nozzles 92, and when the spraying work is carried out, the affinity agent is sprayed from the nozzle 92 to the surface of the sunroof glass by driving the affinity agent conveying equipment to work.

[0049] The synchronous follower device 10 comprises a connecting rod 101, a spring 102, a driving block 103, a follower column 104, a support plate 105, a driving ring 106, a driving groove 107, a driving disc 108 and a pushing block 109. The upper side of the base 1 is slidably connected with two connecting rods 101 corresponding to the positions of the two follower platforms 7, and the connecting rod 101 can rotate around the axis of the support shaft 2. The middle part of the bottom surface of the follower platform 7 is rotatably connected with the end of the connecting rod 101 through a bearing. The outer wall of the connecting rod 101 is fixed with the spring 102, and the end of the spring 102 away from the connecting rod 101 is fixed with the outer wall of the base 1. The end of the connecting rod 101 away from the follower platform 7 is slidably connected with the driving block 103 through a sliding sleeve. The bottom of the driving block 103 is conically arranged. The upper end of the driving block 103 is rotatably connected with the follower column 104 through a bearing. The top of the base 1 is fixed with the support plate 105. The upper end of the support plate 105 is fixed with the driving ring 106. The outer wall of the driving ring 106 is sequentially provided with two driving grooves 107 corresponding to the positions of the two connecting rods 101. One end of the follower column 104 is rollingly inserted into the inner side of the driving groove 107. The outer wall of the support shaft 2 is fixed with the driving disc 108. The top of the driving disc 108 is fixed with a plurality of pushing blocks 109 at equal angles. The pushing block 109 is located directly below the telescopic rod assembly 4. The end of the pushing block 109 close to the driving block 103 is arranged in an inclined manner.

[0050] In use, the motor 3 is driven to rotate, thereby driving the support shaft 2 to rotate, and further driving the telescopic rod assembly 4 to rotate, so as to drive the sunroof glass to be conveyed and transferred, when the sunroof glass reaches the cleaning station 400, the sunroof glass is located directly above the follow-up platform 7, and at the same time, the pushing block 109 abuts against the bottom of the driving block 103, with the rotation of the support shaft 2, the driving block 103 is driven to rotate at the same speed and in the same direction, thereby driving the connecting rod 101 and the follow-up platform 7 to move synchronously with the sunroof glass, so that the plasma cleaning assembly 8 can move with the sunroof glass to perform the cleaning work, with the continuous rotation of the support shaft 2, the follow-up column 104 is gradually moved upward under the action of the driving groove 107, thereby driving the driving block 103 to gradually move upward and separate from the pushing block 109, at the same time when the driving block 103 separates from the pushing block 109, the cleaning work is completed, that is, the plasma cleaning assembly 8 has just completed one rotation around the periphery of the sunroof glass, and then the connecting rod 101 is reset under the action of the spring 102, and then with the continuous rotation of the support shaft 2, the sunroof glass enters the primer application station 500, and the operation process of the primer application station 500 is the same as described above, when the primer application assembly 9 moves with the sunroof glass, the primer application work is performed.

[0051] The synchronous driving device 11 comprises half toothed rings 111, rotating sleeves 112, gears 113, driving rods 114, follow-up rings 115, elastic sheets 116 and protrusions 117, two half toothed rings 111 are fixed on the top of the base 1 and correspond to the positions of the two connecting rods 101, rotating sleeves 112 are rotatably connected to the ends of the connecting rods 101 close to the follow-up platform 7 through bearings, gears 113 are installed on the outer walls of the rotating sleeves 112 through one-way bearings and are in meshing connection with the half toothed rings 111, driving rods 114 are fixed on the upper ends of the outer walls of the rotating sleeves 112, follow-up rings 115 are rotatably connected to the bottoms of the moving blocks 712 through shaft pins, one ends of the driving rods 114 are slidingly inserted into the inner walls of the follow-up rings 115, a plurality of elastic sheets 116 are fixed on the lower ends of the outer walls of the rotating sleeves 112 at equal angles, a plurality of protrusions 117 are fixed on the ends of the connecting rods 101 close to the elastic sheets 116 at equal angles, and each protrusion 117 is located between two adjacent elastic sheets 116.

[0052] When the sunroof glass reaches the cleaning station 400 or the primer station 500, the gear 113 rotates around the support rotating shaft 2 due to the rotation of the connecting rod 101 and the pushing of the half-toothed ring 111. When the connecting rod 101 rotates from the feeding station 300 to the cleaning station 400 or the primer station 500, the gear 113 rotates to drive the rotating sleeve 112 to rotate under the action of the one-way bearing. When the rotating sleeve 112 rotates, the elastic sheet 116 slides off the surface of the protrusion 117. The rotating sleeve 112 drives the driving rod 114 to rotate, thereby driving the moving block 712 to slide on the outer wall of the annular guide rail body 711 through the cooperation of the driving rod 114 and the follower ring 115. When the driving block 103 is separated from the pushing block 109, the gear 113 just rotates one circle, and the moving block 712 moves one circle on the top of the annular guide rail body 711, thereby driving the plasma cleaning assembly 8 or the primer assembly 9 to move one circle around the sunroof glass to complete the cleaning and priming work. After the cleaning or priming work is completed, the connecting rod 101 is reset. At this time, the rotation direction of the connecting rod 101 makes the gear 113 unable to drive the rotating sleeve 112 to rotate, and the plasma cleaning assembly 8 or the primer assembly 9 is stationary relative to the follower platform 7 due to the arrangement of the elastic sheet 116 and the protrusion 117.

[0053] It is emphasized that the driving rod 114 is located above the half-toothed ring 111, so the rotation of the driving rod 114 is not hindered by the half-toothed ring 111, and the driving rod 114 can rotate smoothly. The spring force of the spring 102 is much greater than the spring force of the four elastic sheets 116, so the connecting rod 101 can be reset smoothly. During the conveying of the sunroof glass, the sunroof glass is located between the two plasma cleaning heads 82 and the two nozzles 92, and the suction cup 6 is adsorbed on the middle position of the sunroof glass. The plasma cleaning heads 82 and the nozzles 92 do not hinder the suction cup 6 when rotating around the sunroof glass.

[0054] The top of the base 1 corresponds to the two connecting rods 101, and two arc-shaped sliding rails 12 are fixed. The outer wall of the arc-shaped sliding rail 12 is slidably connected with an arc-shaped sliding block 13. The top of the arc-shaped sliding block 13 is fixed with the outer wall of the corresponding connecting rod 101. The end of the arc-shaped sliding rail 12 close to the spring 102 is fixed with a limiting block 14. The arc-shaped sliding block 13 is in extrusion contact with the outer wall of the limiting block 14, and the limiting block 14 can limit the position of the connecting rod 101.
