Description

Technical Field

[0002] With the increasing demand for the photovoltaic screen printing industry, domestic related automation equipment manufacturers are flourishing, and each is advancing in a healthy competition in the red ocean of cost optimization. Automatic screen printing photovoltaic panels feed photovoltaic panels to the printing machine workbench through an external transmission line. Before printing, the photovoltaic panels need to be automatically adjusted to the specified position. The position of the photovoltaic panels is detected by vision, and then the turntable rotates the positioned photovoltaic panels to the bottom of the printing head. The printing head completes the printing action according to the position information provided by the visual detection. The position positioning of the photovoltaic panels is completed by the paper roll transmission mechanism. The transmission mechanism is driven by a motor. In order to meet the torque required for the paper roll movement of the transmission mechanism, a reducer, such as a planetary reducer, is usually set. However, the addition of a reducer to the transmission mechanism will cause a loss in transmission efficiency, and the position transmission accuracy is also affected by the accuracy of the reducer.

The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0020] like Figure 1 As shown, the embodiment of the present disclosure provides a conveying mechanism 20, which includes a first mounting frame 23, a transmission paper roll 21, a roller 22 and a motor 10; the motor 10 is fixedly mounted on the first mounting frame 23, and its output shaft is connected to the roller 22; the transmission paper roll 21 is laid on the top surface of the first mounting frame 23, and its two ends are respectively fixedly connected to the roller 22, and the roller 22 is arranged in the first mounting frame 23, and is used to rotate under the drive of the motor 10 and drive the transmission paper roll 21 to move, and the area of ​​the transmission paper roll 21 located on the top surface of the first mounting frame 23 is used for placing the photovoltaic panel 40.

[0021] In one example of this embodiment, a roller and a motor are respectively provided, and the output shaft of the motor is connected to the roller, thereby driving the roller to rotate; in another example, a motor and two rollers are provided, and the output shafts of the motor are respectively connected to the two rollers, thereby driving the two rollers to rotate; and in yet another example, two motors and two rollers may be provided, and the output shafts of the two motors are respectively connected to the two rollers, thereby driving the two rollers to rotate.

[0022] The transmission mechanism provided in this embodiment directly connects the output shaft of the motor to the roller, thereby eliminating the need for a speed reducer, improving transmission efficiency and transmission accuracy and reducing the cost of the transmission mechanism.

[0023] In this embodiment, the power of the motor is greater than the minimum power required by the transmission mechanism, that is, the power of the motor is greater than the power actually required by the transmission mechanism, so that the motor can provide sufficient output torque to drive the movement of the transmission roll and ensure the stable operation of the transmission mechanism. For example, the transmission mechanism only needs a 100W motor to operate normally, but the power of the motor actually used is 120W or 150W or a motor with higher power is used.

[0024] like Figure 2As shown, the motor 10 is used to drive the movement of the transmission roll 21 carrying the photovoltaic panel 40, and the flange size of the motor 10 is less than or equal to 40mm, and / or the power of the motor 10 is greater than 100W.

[0025] The motor 10 provided in the embodiment of the present disclosure satisfies the torque required for the movement of the transmission paper roll 21 of the photovoltaic panel transmission mechanism 20 by setting the power of the small-sized driving motor 10 to be greater than 100W, thereby eliminating the need for a reducer, improving transmission efficiency, improving transmission accuracy and reducing costs.

[0026] As some of the preferred methods, the inventors have found through research that when the power of the motor 10 is set to 150W, 200W, 300W, 350W or 400W, the transmission efficiency can be greatly improved.

[0027] As some of the preferred methods, the inventors have found through research that when the flange size of the motor 10 is 40 mm or 25 mm, setting the power of the motor 10 to the above-mentioned specific values ​​can further improve the transmission efficiency, and a small-sized and high-power motor can reduce the installation space used to install the motor.

[0028] It can be understood that the above-mentioned flange size refers to a size that is equivalent to the stator outer diameter size of the motor, and the difference between the flange size and the stator outer diameter size is in the range of 1-3 mm.

[0029] As one example, a synchronous wheel 11 is provided at the front end of the motor 10, and the synchronous wheel 11 is fixedly connected to the output shaft. The output shaft is used to connect to the roller 22 through the synchronous wheel 11, the conveyor belt 25 and the driven pulley 26 to drive the transmission roll paper 21 to move.

[0031] As one example, the mounting grooves 121 may be respectively provided at the upper and lower ends of the fixing block 12 , or the mounting groove 121 may be provided at only one end.

[0032] It is understandable that the motor 10 can be fixed to the transmission mechanism 20 by installing screws on the mounting slots 121 .

[0033] As one example, the conveying mechanism 20 further includes two driven rollers 24 , and the two driven rollers 24 are respectively arranged on two sides of the top surface of the first mounting frame 23 that are perpendicular to the moving direction of the top surface of the transmission roll paper 21 .

[0034] The beneficial effect of the conveying mechanism provided by the embodiment of the present disclosure is that by directly connecting the output shaft of the motor with the roller, the reducer is omitted, the conveying efficiency of the conveying mechanism is improved, the conveying accuracy is improved, and the cost is reduced.

[0035] The disclosed embodiment also provides a rotary table 30, the rotary table 30 includes a second mounting frame 31 and a rotating device, at least two sides of the second mounting frame 31 are respectively provided with the above-mentioned conveying mechanism 20, the bottom surface of the second mounting frame 31 is provided with a fixing hole, the rotating device is connected to the fixing hole, and is used to drive the conveying mechanism 20 to rotate. The rotary table of this embodiment is used to convey the photovoltaic cell panel to the printing machine workbench, adjust the photovoltaic cell panel to a specified position before printing, visually detect the position of the photovoltaic cell panel, and then the rotary table rotates the positioned photovoltaic cell panel to the bottom of the printing head.

[0036] As one example, the second mounting frame 31 has four side surfaces perpendicular to the bottom surface, and each side surface is fixedly provided with a transmission mechanism 20. In this embodiment, by providing four transmission mechanisms, the working efficiency of the rotary workbench can be greatly improved.

[0037] In this embodiment, the rotating device includes a rotating motor, and a rotating shaft of the rotating motor is connected to the fixing hole.

[0038] The beneficial effect of the rotary workbench provided by the embodiment of the present disclosure is that by directly connecting the output shaft of the motor that drives the transmission mechanism to move with the roller, the reducer is omitted, the transmission efficiency is improved, the transmission accuracy is improved, and the cost is reduced.

[0039] In this embodiment, the power of the driving motor 10 of the rotating worktable 30 is set to be greater than 100 W, so that the torque required for the transmission roll 21 of the photovoltaic panel transmission mechanism 20 is met, and the transmission efficiency is further improved.

[0040] It should be understood that the application of the present invention is not limited to the above examples.
