Description

Technical Field

[0001] The utility model relates to the technical field of flat screen printing equipment, and particularly relates to a sheet combining conveyor with synchronous lifting of suckers. Background Art

[0002] A sheet combining conveyor is an auxiliary device used in the printing process of automobile front windows. This device is mainly used to combine two pieces of glass that have been printed on different production lines, and then bend them together to ensure the consistency of the bending arcs of the two pieces of glass.

[0003] The Chinese patent document with the authorization announcement number CN203332962U of the applicant's prior application discloses a sheet combining conveyor. The sheet combining conveyor includes a transmission frame mechanism, a lifting bracket mechanism, and a sheet combining positioning mechanism. The sheet combining positioning mechanism includes a gantry bracket, a positioning point bracket, a servo motor, a sucker, and a positioning point. The sucker is driven by a cylinder. The design of this device has the following defects: multiple suckers on the sheet combining positioning mechanism are driven by the independent lifting operations of multiple cylinders, that is, each sucker is individually controlled for lifting by a cylinder. Therefore, during the lifting process of the suckers, the lifting of each sucker may be inconsistent due to reasons such as different air path lengths, different control solenoid valves used for different groups of cylinders, and incomplete consistency in the speed settings of each speed regulating valve, resulting in inconsistent lifting actions of the cylinders and causing the suckers to lift out of sync. When the suckers lift out of sync, it will cause some suckers to have adsorbed the glass and start to rise, while some suckers do not perform the rising action, and it is impossible to keep all suckers in the same plane, which will cause the glass to fall off. Therefore, further optimization design is needed to solve the problem of out-of-sync sucker lifting to improve the stability of the device during use. Summary of the Utility Model

[0024] To enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] As shown in Figure 1 and Figure 4 A sheet combining and transporting machine with synchronous lifting of suckers includes a transmission rack mechanism 01, a lifting bracket mechanism 02, and a sheet combining and positioning mechanism 03. The lifting bracket mechanism 02 is connected below the transmission rack mechanism 01, and the sheet combining and positioning mechanism 03 is connected to the lifting bracket mechanism 02. The sheet combining and positioning mechanism 03 includes a gantry bracket 31, a sucker mounting crossbeam frame 32, a servo motor 33, a second driven pulley 34, a second driving pulley 35, a positioning point 36, suckers 37, and a crank connecting rod assembly 38. The sucker mounting crossbeam frame 32 is mounted on the gantry bracket 31 through the crank connecting rod assembly 38, and a plurality of the suckers 37 are mounted on the lower part of the sucker mounting crossbeam frame 32. All the suckers 37 are mounted on the sucker mounting crossbeam frame 32 and are driven by the crank connecting rod assembly 38, and can stably lift the glass sheet by 40 mm to ensure the positioning of the lower glass sheet.

[0026] As shown in Figure 4 Two of the crank connecting rod assemblies 38 are respectively arranged on the left and right sides of the gantry bracket 31.

[0027] As shown in Figure 2As shown in the figure, the transmission rack mechanism 01 includes a synchronous belt 11, a first driving pulley 12, a first driven pulley 13, a reduction motor 14, a lifting cylinder 15, a pull rod 16, a crank rocker 17, a first aligning bearing 18, a rack 19 and a floor footing 20. The two ends of the transmission rack mechanism 01 are provided with a first driving pulley 12 and a first driven pulley 13, and a reduction motor 14 for controlling the synchronous belt 11 is provided. A lifting cylinder 15 is provided on the pull rod 16. One end of the crank rocker 17 is provided with a first aligning bearing 18, and the bottom end of the rack 19 is provided with a floor footing 20.

[0028] As Figure 3 shown in the figure, the lifting bracket mechanism 02 includes a material supporting block 21, a second aligning bearing 22 and a lifting bracket 23. The lifting bracket mechanism 02 is provided with a lifting bracket 23. Four second aligning bearings 22 are provided at the bottom of the lifting bracket 23, and a material supporting block 21 is provided at the upper part of the lifting bracket 23.

[0029] As Figure 4 shown in the figure, a cross-shaped positioning point bracket is provided at the lower part of the gantry bracket 31. Second driven pulleys 34 are provided at one end in both directions of the positioning point bracket, second driving pulleys 35 are provided at the other end, and positioning points 36 moving in both directions and servo motors 33 capable of driving the positioning points 36 are provided.

[0030] The glass sheet combining and conveying machine provided by the present utility model can realize the full-automatic production of front windshield glass of various specifications from glass sheet loading, positioning and combining to glass sheet unloading.

After the next glass sheet is fed in, the lifting and centering and clamping positioning actions are repeated. Then the upper glass sheet descends to a low position, the suction cups 37 deflate and place the glass sheet on the upper surface of the lower glass sheet, and finally the two glass sheets are conveyed out of this device together. Moreover, when the size specification of the glass sheet changes, only the locking block of the corresponding positioning point 36 needs to be loosened, and the positioning point 36 is pushed to a suitable position and locked.

[0031] The utility model solves the problem of asynchronous lifting of each suction cup 37 by arranging a suction cup mounting crossbeam frame 32 and a crank connecting rod assembly 38 in the laminating positioning mechanism 03 of the laminating conveyor, and mounting all the suction cups 37 on the suction cup mounting crossbeam frame 32, thereby improving the stability of the device during use.
