[0002] In the production process of solar cells, laser scribing is used to cut the solar cells into two parts, and the cut solar cells are passivated and coated to improve the performance of the solar cells. Before the cut cells are passivated, the silicon wafers are generally sucked up by a suction cup and moved into a material box for transportation to the passivation equipment. However, when the existing suction cup is used to transport the silicon wafer, it takes a long time to wait for the suction cup to release the vacuum state to release the silicon wafer, which greatly reduces the transportation efficiency of the silicon wafer.

[0029] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0030] The present application provides a suction cup 233, such as Figures 1 to 3 As shown, the suction cup 233 includes a suction cup body 2331 and a plurality of suction nozzles 2332. The plurality of suction nozzles 2332 are mounted on the suction cup body 233 and are configured to absorb or release the workpiece. The workpiece may be a silicon wafer, a battery cell or other component, which is not limited in this application and can be selected by those skilled in the art according to actual conditions.

[0031] In some embodiments, the suction cup body 2331 is provided with an airflow channel 23311, a plurality of suction nozzle holes 23312, and an interface, and the airflow channel 23311 is respectively connected to the interface and the plurality of suction nozzle holes 23312. The plurality of suction nozzles 2332 are arranged in one-to-one correspondence at the suction nozzle holes 23312 and are connected to the suction nozzle holes 23312. The interface is configured to be connected to the external vacuum breaking valve 220.

[0032] It should be noted that the external vacuum device (not shown) is configured to be connected to the external vacuum breaker valve 220, and when the external vacuum breaker valve 220 is in a closed state, the external vacuum device can extract the air in the suction cup 233 through the interface to achieve vacuum adsorption of each suction nozzle 2332.

[0033] It can be understood that when the workpiece needs to be adsorbed, the external vacuum breaking valve 220 is closed, and the external vacuum device extracts the air in the air flow channel 23311 through the interface. Since the air flow channel 23311 is connected to multiple suction nozzle holes 23312, multiple suction nozzles 2332 can reach a vacuum state at the same time to adsorb the workpiece.

[0034] When the workpiece needs to be released from the suction cup 233, the external vacuum breaking valve 220 is started, and the external vacuum breaking valve 220 applies pressure to the suction cup body 2331 through the interface, so that the airway inside each suction nozzle 2332 is connected to the external air, thereby releasing the vacuum state between the suction cup 233 and the workpiece and releasing the workpiece.

[0035] Compared with the existing suction cup, the suction cup 233 in the present application can realize the simultaneous adsorption of workpieces by controlling multiple suction nozzles 2332 through an external air pipe through the setting of the interface and the air flow channel 23311, without connecting the air pipe to each suction nozzle 2332, thereby reducing the risk of stagnation of the suction mechanism 230 due to the complexity of the air pipe when driving the suction cup 233 to move, and can also quickly release the vacuum state of the suction cup 233, saving the downtime waiting time of the suction mechanism 230, thereby improving the handling efficiency of the suction mechanism 230.

[0036] In some embodiments, the first direction is defined as the length direction of the suction cup body 2331, and the second direction is defined as the width direction of the suction cup body 2331, and the first direction is perpendicular to the second direction. In other embodiments, the first direction may also intersect with the second direction and is not perpendicular, and this application does not limit this, and those skilled in the art may select according to actual conditions.

[0037] like Figure 3 As shown, the airflow channel 23311 includes a first flow channel 23311a, a second flow channel 23311b and a third flow channel 23311c, and the first flow channel 23311a and the second flow channel 23311b are both arranged along the first direction and are parallel to each other. The third flow channel 23311c is arranged along the second direction and connects the first flow channel 23311a and the second flow channel 23311b. In other words, the first flow channel 23311a, the second flow channel 23311b and the third flow channel 23311c are connected to each other.

[0038] In some embodiments, the first flow channel 23311a and the second flow channel 23311b are both provided with the above-mentioned suction nozzle 2332 hole 23312. Thus, the suction area of ​​the suction cup 233 is increased, so that the suction force generated by the suction cup 233 can be evenly distributed on the workpiece, reducing the risk of the workpiece falling due to uneven suction force.

[0039] It can be understood that when the workpiece needs to be adsorbed, the external vacuum breaking valve 220 is closed, and the external vacuum device draws air in the air flow channel 23311 through the interface so that the suction nozzle 2332 distributed in the first flow channel 23311a and the suction nozzle 2332 in the second flow channel 23311b reach a vacuum state to adsorb the workpiece.

[0040] When the workpiece needs to be released, the external vacuum breaking valve 220 is started, and the external vacuum breaking valve 220 applies pressure to the air flow channel 23311 through the interface to connect the air flow channel 23311 as a whole with the external air, thereby releasing the vacuum state between the suction cup 233 and the workpiece and releasing the workpiece.

[0041] In some embodiments, Figure 1 and Figure 3 As shown, there are two interfaces, namely, the first interface 23313 and the second interface 23314. The first interface 23313 is arranged in the first flow channel 23311a, and the second interface 23314 is arranged in the second flow channel 23311b. When the suction cup 233 sucks the workpiece, the external vacuum device can extract the air in the air flow channel 23311 through the first interface 23313 and the second interface 23314 at the same time, so that the suction nozzle 2332 quickly reaches a vacuum state and sucks the workpiece.

[0042] When the workpiece needs to be released, the external vacuum breaking valve 220 can simultaneously flow to the air flow channel 23311 through the first interface 23313 and the second interface 23314 to quickly connect the air flow channel 23311 to the external air, thereby breaking the vacuum state between the suction cup 233 and the workpiece and releasing the workpiece.

[0043] It should be noted that by providing two interfaces, the speed at which the suction cup 233 reaches the vacuum adsorption state and releases the vacuum adsorption state can be increased, thereby further improving the efficiency of the suction cup 233 in transporting the workpiece.

[0044] In other embodiments, the number of interfaces may be 3, 4 or other numbers. The first interface 23313 may be arranged in the second channel 23311b or the third channel 23311c, and the second interface 23314 may be arranged in the first channel 23311a and the third channel 23311c. Alternatively, the first interface 23313 and the second interface 23314 may be arranged in the same channel. The present application does not limit this, and those skilled in the art may choose according to actual conditions.

[0045] In some embodiments, Figure 3As shown, the first flow channel 23311a passes through two opposite ends of the suction cup body 2331. Alternatively, in some embodiments, the second flow channel 23311b passes through two opposite ends of the suction cup body 2331. Alternatively, in some embodiments, both the first flow channel 23311a and the second flow channel 23311b pass through two opposite ends of the suction cup body 2331.

[0046] It can be understood that when manufacturing the suction cup 233 of the present application, the technician only needs to use a drill bit to drill from one end of the suction cup body 2331 to the other end of the suction cup body 2331 along the first direction. For example, drilling from the left end of the suction cup body 2331 to the right end of the suction cup body 2331 can form the first flow channel 23311a and the second flow channel 23311b.

[0047] By configuring the first flow channel 23311a or the second flow channel 23311b to pass through the two opposite ends of the suction cup body 2331, it is convenient for technicians to process and manufacture the suction cup 233, which is conducive to large-scale production of the suction cup 233.

[0048] It should be noted that when processing the third flow channel 23311c, technicians can also use the same drilling method to drill a hole from the end of the suction cup body 2331 and connect the first flow channel 23311a and the second flow channel 23311b to form the third flow channel 23311c.

[0049] It is worth noting that after the processing of the suction cup 233 is completed, that is, the processing of the first flow channel 23311a, the second flow channel 23311b and the third flow channel 23311c is completed, it is necessary to seal the ends of the first flow channel 23311a and the second flow channel 23311b through a plurality of top screws (not shown) to ensure the sealing of the air flow channel 23311, thereby ensuring that the suction cup 233 can vacuum absorb the workpiece.

[0050] In some embodiments, the number of the nozzle holes 23312 is an even number. All the nozzle holes 23312 are divided into two nozzle hole groups (not shown), one of the two nozzle hole groups is arranged in the first flow channel 23311a, and the other is arranged in the second flow channel 23311b. In some embodiments, the multiple nozzle holes 23312 in each nozzle hole group are arranged at equal intervals.

[0051] It should be noted that by providing two rows of suction nozzles 2332 and arranging the suction nozzles 2332 in each row at equal intervals, not only can the suction cup 233 adsorb the workpiece more evenly and stably to reduce the risk of the workpiece falling due to uneven adsorption force, but the structure of the suction cup 233 can also be made more compact, reducing the space occupied by the suction cup 233.

[0052] For example, Figure 3As shown, the number of nozzle holes 23312 is 8, and the 8 nozzle holes 23312 are grouped into 4, and divided into two nozzle hole groups. One of the two nozzle hole groups is arranged in the first flow channel 23311a, and the other is arranged in the second flow channel 23311b. Among them, the 4 nozzle holes 23312 in each nozzle hole group are arranged at equal intervals along the first direction in the corresponding flow channel.

[0053] In other embodiments, the number of the nozzle holes 23312 may be 10, 12 or other numbers, and the nozzle holes 23312 may be arranged in other arrangements. This application does not limit this, and those skilled in the art may choose according to actual conditions.

[0054] The present application also provides a suction mechanism 230, such as Figure 4 As shown, the suction mechanism 230 includes a mounting frame 231, a driving assembly 232, and at least one suction cup 233. The driving assembly 232 is mounted on the mounting frame 231, and the suction cup 233 is mounted on the driving assembly 232, and is connected to the external vacuum breaking valve 220 through an interface in the suction cup 233. The driving assembly 232 is configured to drive the suction cup 233 to move in a direction close to or away from the workpiece to absorb or release the workpiece.

[0055] It can be understood that when the workpiece needs to be adsorbed, the external vacuum breaking valve 220 is in a closed state, the driving component 232 drives the suction cup 233 to move towards the workpiece, and the external vacuum device extracts the air in the air flow channel 23311 through the interface of the suction cup 233. Since the air flow channel 23311 is connected to multiple suction nozzle holes 23312, multiple suction nozzles 2332 can reach a vacuum state at the same time to adsorb the workpiece.

[0056] When the workpiece needs to be released, the driving component 232 drives the suction cup 233 to move towards the workpiece. At this time, the external vacuum breaking valve 220 is opened. The external vacuum breaking valve 220 applies pressure to the suction cup body 2331 through the interface in the suction cup 233, so that the airway inside each suction nozzle 2332 is connected to the external air, thereby releasing the vacuum state between the suction cup 233 and the workpiece and releasing the workpiece.

[0057] It should be noted that the suction mechanism 230 provided in the present application adopts the above-mentioned suction cup 233, which not only can realize an external air pipe to control multiple suction nozzles 2332 to simultaneously adsorb workpieces without connecting the air pipe to each suction nozzle 2332, thereby reducing the risk of stagnation of the suction mechanism 230 due to the complexity of the air pipe when driving the suction cup 233 to move, but also can quickly release the vacuum state of the suction cup 233 through the vacuum breaking valve 220, saving the downtime waiting time of the suction mechanism 230, thereby improving the handling efficiency of the suction mechanism 230.

[0058] In some embodiments, the driving assembly 232 includes a cylinder slide 2321, the cylinder slide 2321 is disposed on the mounting frame 231, and the suction cup 233 is mounted on the cylinder slide 2321. When it is necessary to adsorb or release the workpiece, the suction mechanism 230 drives the suction cup 233 to move toward or away from the workpiece through the cylinder slide 2321, so that the suction cup 233 adsorbs or releases the workpiece. It should be noted that the cylinder slide 2321 is not only simple in structure and easy to operate, but also has a low cost compared to electric and hydraulic systems, which can greatly reduce the operation and maintenance costs of the suction mechanism 230.

[0059] In some embodiments, Figure 4 As shown, the driving assembly 232 further includes a throttle valve 2323 and a solenoid valve 2322, the throttle valve 2323 is installed with the cylinder slide 2321, and the solenoid valve 2322 is installed on the external manipulator 210 and connected to the throttle valve 2323. The solenoid valve 2322 is configured to control the reciprocating sliding of the cylinder slide 2321, and the throttle valve 2323 is configured to adjust the air intake of the cylinder slide 2321 to control the reciprocating sliding speed of the cylinder slide 2321.

[0060] It can be understood that when the suction cup 233 needs to be brought close to the workpiece, the solenoid valve 2322 controls the cylinder slide 2321 to slide in the direction close to the workpiece, so that the suction cup 233 is close to the surface of the workpiece, thereby achieving the purpose of sucking the workpiece. When the suction cup 233 needs to be moved away from the workpiece, the solenoid valve 2322 controls the cylinder slide 2321 to slide in the direction away from the workpiece, so that the suction cup 233 leaves the surface of the workpiece, thereby achieving the purpose of releasing the workpiece.

[0061] It is worth noting that when the solenoid valve 2322 controls the movement of the cylinder slide 2321 (specifically, the movement in the direction of approaching or moving away from the workpiece), the throttle valve 2323 can adjust the air intake of the cylinder slide 2321 to control the movement speed of the cylinder slide 2321. Through the cooperation of the solenoid valve 2322 and the throttle valve 2323, the rhythm of sucking and transporting the workpiece can be accurately controlled, that is, the speed of the sucking mechanism 230 sucking the workpiece can be controlled.

[0062] For example, if the movement speed of the cylinder slide 2321 is too slow, the technician can increase the air intake of the cylinder slide 2321 through the throttle valve 2323, thereby increasing the movement speed of the cylinder slide 2321, that is, increasing the speed at which the suction cup 233 adsorbs or releases the workpiece.

[0063] If the movement speed of the cylinder slide 2321 is too fast, the technician can reduce the air intake of the cylinder slide 2321 through the throttle valve 2323, thereby reducing the movement speed of the cylinder slide 2321, that is, reducing the speed at which the suction cup 233 absorbs or releases the workpiece.

[0064] The present application further provides a transport device 200, such as Figure 5 As shown, the handling device 200 includes a manipulator 210 , a vacuum breaker valve 220 and the above-mentioned suction mechanism 230 . The suction mechanism 230 and the vacuum breaker valve 220 are both installed on the manipulator 210 , and the vacuum breaker valve 220 is connected to the suction cup 233 in the suction mechanism 230 .

[0065] The manipulator 210 is configured to drive the suction mechanism 230 to move to the target position. It is worth noting that the manipulator 210 can not only accurately control the position and movement of the suction mechanism 230 to achieve accurate handling of the workpiece, but also perform programming control according to actual needs, so that the handling device 200 has higher flexibility and adaptability.

[0066] In other embodiments, other driving mechanisms may also be used, which are not limited in the present application and those skilled in the art may select according to actual conditions.

[0067] It should be noted that the target position includes a first target position and a second target position. The first target position is the position of the workpiece on the external feeding mechanism (not shown), and the second target position is the position of the tray (not shown) for accommodating the workpiece.

[0068] It is understandable that when a workpiece needs to be transported, the robot 210 first drives the suction mechanism 230 to move to the first target position, and then the driving component 232 in the suction mechanism 230 drives the suction cup 233 to move toward the workpiece to absorb the workpiece.

[0069] After the suction cup 233 absorbs the workpiece, the manipulator 210 drives the suction mechanism 230 to move to the second target position. After moving to the second target position, the suction cup 233 releases the target workpiece, and the driving component 232 drives the suction cup 233 to move away from the workpiece, so as to realize the transport of the workpiece.

[0070] It should be noted that when releasing the workpiece, the vacuum breaking valve 220 is in an open state. The vacuum breaking valve 220 applies pressure to the suction cup body 2331 through the interface in the suction cup 233, so that the air passage inside each suction nozzle 2332 is connected to the external air, thereby releasing the vacuum state between the suction cup 233 and the workpiece and releasing the workpiece.

[0071] In summary, the conveying device 200 provided in the present application, by setting a vacuum breaking valve 220 and adopting the above-mentioned suction mechanism 230, can not only realize that one external air pipe controls multiple suction nozzles 2332 to simultaneously adsorb workpieces without connecting the air pipe to each suction nozzle 2332, thereby reducing the risk of stagnation of the suction mechanism 230 due to the complexity of the air pipe when driving the suction cup 233 to move, but also can quickly release the vacuum state of the suction cup 233 through the vacuum breaking valve 220, thereby saving the downtime waiting time of the conveying device 200, thereby improving the conveying efficiency of the conveying device 200.

[0072] In some embodiments, Figure 5 As shown, the handling device 200 further includes a connector 240, one end of which is connected to the output end of the manipulator 210, and the other end of which is connected to the mounting bracket 231 in the suction mechanism 230. The connector 240 can be a mechanical connector in various forms, such as a screw, etc., and the specific form can be selected according to actual needs.

[0073] It can be understood that when the manipulator 210 is working, the connecting member 240 can transmit the power of the manipulator 210 to the suction mechanism 230, so that the suction mechanism 230 can move according to a predetermined path, thereby achieving accurate transportation of the workpiece.

[0074] In addition, the connection member 240 can extend the service life of the suction mechanism 230 and facilitate the maintenance or replacement of the suction cup 233. Specifically, the technician only needs to disconnect the connection member 240 from the manipulator 210 to repair or replace the suction cup 233, and does not need to repeatedly disassemble the suction mechanism 230.

[0075] The present application further provides a solar cell processing device 1, such as Figure 6 As shown, the solar cell processing equipment 1 includes a frame 100 and the above-mentioned transport device 200, and the transport device 200 is installed on the frame 100. Specifically, the frame 100 can be a platform or a bracket for supporting the transport device 200 and the workpiece to be sucked to ensure the stability and safety of the suction mechanism 230.

[0076] The solar cell processing equipment 1 in the present application is provided with the above-mentioned conveying device 200.
