[0027] like Figure 1 , Figure 2As shown, a processing table device of a laser scribing device has a motor 125 installed on a processing table bottom plate 126, a processing turntable 121 installed on the rotating shaft of the motor 125, a plurality of processing platforms 122 distributed on the processing turntable 121, an adsorption air channel is provided in the processing platform 122, a plurality of adsorption ports connected with the adsorption air channel are distributed on the working surface of the processing platform 122, a backlight source 124 is provided below the rotation track of the processing platform 122, a movable end of an air slip ring 123 is fixed on a slip ring movable end fixing plate 128, the slip ring movable end fixing plate 128 is installed on the processing turntable 121, an air inlet of each processing platform 122 is connected to a movable end interface of the air slip ring 123, a fixed end of the air slip ring 123 is fixed on a solenoid valve fixing plate 131 of a vacuum component 13, and the vacuum component 13 is fixed to a marble column 111 of an optical path component 11 through a profile 132.
[0028] like Figure 3 , Figure 4 As shown, the vacuum assembly 13 includes a vacuum generator 133, a vacuum solenoid valve 134, a vacuum breaking solenoid valve 135, a reducing cross four-way joint 1312 and a vacuum breaking solenoid valve air inlet five-way joint 1316, a main air pipe 137 is connected to a vacuum breaking air pipe 138 and a vacuum solenoid valve air pipe 139, the vacuum solenoid valve air pipe 139 is connected to the air inlet of the vacuum solenoid valve 134, the air outlet of the vacuum solenoid valve 134 is connected to the air inlet of the vacuum generator 133 through a vacuum generator air supply pipe 1310, and the vacuum generator 13 The air outlet of the reducing cross-shaped joint 1312 is connected to the vacuum air inlet end of the reducing cross-shaped joint 1312 through a vacuum air pipe 1311, the vacuum pressure end of the reducing cross-shaped joint 1312 is connected to the air inlet of the vacuum pressure gauge 136 through a vacuum gauge air pipe 1313, the vacuum air outlet end of the reducing cross-shaped joint 1312 is connected to the fixed end interface of the air slip ring 123 through an air slip ring air inlet pipe 1314, and the movable end interface of the air slip ring 123 is connected to the air inlet of the processing platform 122 through a processing platform air inlet pipe 1315;
[0029] The vacuum breaking air pipe 138 is connected to the main air inlet of the vacuum breaking solenoid valve five-way air inlet joint 1316, the vacuum breaking air inlet end of the cross reducing four-way joint 1312 and the air outlet of the vacuum breaking solenoid valve 135 are connected through the vacuum breaking air pipe 1317, and the air inlet of the vacuum breaking solenoid valve 135 and the branch port of the vacuum breaking solenoid valve five-way air inlet joint 1316 are connected through the vacuum breaking solenoid valve air inlet pipe 1318, forming a closed loop.
[0030] In specific applications, before the solar cell is placed on the processing platform 122, the vacuum solenoid valve 134 is energized and supplies air to the vacuum generator 133 through the vacuum generator air supply pipe 1310, so that the vacuum generator 133 works to generate adsorption flow, and the adsorption flow enters the processing platform 122 through the vacuum air pipe 1311, the reducer cross four-way joint 1312, the air slip ring air inlet pipe 1314 and the processing platform air inlet pipe 1315, and the vacuum flow reaches the vacuum pressure gauge 136 through the vacuum gauge air pipe 1313 to detect the vacuum value generated in the processing platform 122. When the solar cell falls and sticks to the processing platform 122, the adsorption port on the working surface of the processing platform 122 is shielded by the solar cell, and a vacuum value is generated. When this vacuum value exceeds the preset threshold of the vacuum pressure gauge 136, the control system controls the motor 125 to rotate clockwise.
[0031] The motor 125 rotates 90° clockwise to rotate the solar cell to be directly above the backlight source 124 for CCD detection. During the rotation process, the threshold detected by the vacuum pressure gauge 136 must always be higher than the preset threshold. If it is lower than the preset threshold, an alarm signal will be given.
[0032] After the CCD detection is completed, the motor 125 continues to rotate 90° clockwise to rotate the solar cell to the position directly below the laser scribing station for laser scribing.
[0033] After the laser scribing is completed, the motor 125 continues to rotate 90° clockwise.
[0034] After the solar cell reaches the unloading position, the vacuum solenoid valve 134 is closed, the vacuum generator 133 stops working, the vacuum is maintained, and the whole process ends while waiting for the subsequent mechanism to take the material.
[0035] In summary, the present invention has a unique design and a novel structure. When the motor is working, the active end of the air slip ring is driven to rotate through the processing turntable and the slip ring active end fixing plate installed thereon, thereby ensuring that each processing platform has air supply, establishes vacuum, and has stable adsorption; the motor, backlight source and processing platform bottom plate are fixedly installed, and the fixed end of the air slip ring is fixed on the solenoid valve fixing plate of the vacuum component to prevent the fixed end of the air slip ring from rotating with the processing turntable; an adsorption air channel is arranged in the processing platform to improve the vacuum establishment time and reduce the weight at the same time, so that the motor load is reduced by more than 40%, which can increase the production efficiency of the solar cell module, improve the time of the laser scribing station, and greatly improve the production capacity of the whole machine.
