[0044] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without making creative efforts shall fall within the protection scope of the present application.

[0045] The applicant has developed a loading and unloading active connection device, which can be applied to the laser scribing production line of photovoltaic cells, and can perform the transfer operation of workpieces between the front station and the rear station with different height differences, solve the transfer problem caused by too large height difference, is convenient and stable to control, has a small floor area, and a high transfer efficiency.

[0046] Specifically, please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic structural view of an embodiment of the loading and unloading active connection device of the present application, Figure 2 and

[0047] As Figure 1 and Figure 2 shown, the device includes a housing 10, and openings 101 are arranged on both end faces of the housing 10 in the X-axis direction. In specific applications, one of the openings 101 can be used to dock with the loading and unloading station, that is, the station for placing raw materials and processed workpieces; the other opening 101 can be used to dock with the processing station, that is, the laser scribing station.

[0048] Since there is a large height difference between the loading and unloading station and the processing station, a clamping jaw 20 and a support plate 30 that can extend out from one side opening 101 are provided inside the housing 10.

[0049] The clamping jaw 20 includes a clamping end 201 for clamping the workpiece, and the support plate 30 includes a bearing area 301 for bearing the workpiece.

[0050] Among them, both the clamping jaw 20 and the support plate 30 can move in the X-axis direction and the Z-axis direction, so that the clamping jaw 20 can extend out from one side opening 101 and descend to the loading and unloading station, or can move to the bearing area 301 of the bracket to complete the operation of transferring the workpiece between the bearing area 301 and the loading and unloading station; the support plate 30 can extend out from the other side opening 101 and rise to the processing station to complete the operation of putting the workpiece into or taking out the processing station.

[0051] It should be noted that the above only shows an application scenario of the connection device of the present application. In other embodiments, the connection device may not be used for transferring workpieces between the loading and unloading station and the processing station, and may also be used for transferring workpieces in other scenarios, and can also achieve the effects of this embodiment.

[0052] The following details the structures of the clamping jaw 20 and the support plate 30 of the present application. Please refer to Figure 3 , Figure 3 which is a schematic structural view of an embodiment of the clamping jaw of the present application.

[0053] As Figure 3 shown, the clamping jaw 20 includes a clamping cylinder 202. The clamping cylinder 202 includes two telescopic ends 203 oppositely arranged in the X-axis direction, and the clamping cylinder 202 is used to drive the telescopic ends 203 to horizontally expand and contract.

[0054] Each telescopic end 203 is equipped with a clamping arm 204, and a pair of clamping arms 204 cooperate to form a clamping end 201. To ensure clamping stability, a first limit protrusion 205 is arranged at the end of the clamping arm 204 facing away from the clamping cylinder 202. The first limit protrusion 205 protrudes from the clamping arm 204 in the direction of the gap between the pair of clamping arms 204, thus preventing the workpiece from falling during the clamping process.

[0055] In addition, to prevent the workpiece from accidentally falling during the clamping process, in this embodiment, the jaw 20 further includes an in-position detection mechanism 206. Specifically, the in-position detection mechanism 206 is arranged on the bottom surface of the clamping cylinder 202, and the in-position detection mechanism 206 includes a detection head pointing to the clamping end 201.

[0056] In this embodiment, the in-position detection mechanism 206 can be a photoelectric sensor, which can detect whether the workpiece is located at the clamping end 201 and send a signal for alarm in time when the workpiece does not fall actively, avoiding errors in subsequent processing. In other embodiments, the in-position detection mechanism 206 can also be any other device that can achieve the above functions, such as other types of sensors, etc., which will not be elaborated here.

[0057] Please refer to Figure 4 , Figure 4 which is a schematic structural diagram of an embodiment of the pallet of the present application. As Figure 4 shown, the pallet 30 includes a plate body 302. The plate body 302 includes a first end 3021 and a second end 3022 arranged opposite to each other. To facilitate the transfer of the workpiece by the pallet 30, the loading area 301 can be arranged on the surface of the plate body 302 near the first end 3021.

[0058] To ensure the stability of the workpiece when placed on the pallet 30 and improve the transfer accuracy of the workpiece, the surface height of the loading area 301 can be lower than the surface height of other areas of the plate body 302, so that a limit step 306 is formed between the loading area 301 and other areas of the plate body 302.

[0059] In addition, a second limit protrusion 303 is arranged at the end of the loading area 301 surface near the first end 3021, so that the second limit protrusion 303 can cooperate with the limit step 306 to limit the workpiece.

[0060] Since the end of the pallet 30 is used to carry the workpiece, to ensure the balance of the pallet 30 during movement, a counterweight 304 is also arranged on the surface of the pallet 30 near the second end 3022 to ensure the weight balance at both ends of the pallet 30.

[0061] To facilitate the gripper 20 to pick up and place workpieces on the bearing area 301, clamping avoidance holes 305 are arranged on both sides of the bearing area 301 in the X-axis direction. The clamping avoidance holes 305 on one side extend from the inside of the bearing area 301 to the first end 3021, and the clamping avoidance holes 305 on the other side extend from the inside of the bearing area 301 in the direction away from the first end 3021 to the outside of the bearing area 301.

[0076] Specifically, the rodless cylinder 701 may be a magnetic coupling rodless cylinder 701, and the second X-axis slide 702 may be connected to the magnetic ring slide outside the magnetic coupling rodless cylinder 701 to achieve X-axis motion control of the second X-axis slide 702.

[0077] The support plate 30 can be arranged on the second X-axis slide plate 702, so as to realize the movement control of the support plate 30 in the X-axis direction and the Y-axis direction.

[0078] It should be noted that in other embodiments, the second X-axis displacement unit 70 and the second Z-axis displacement unit 80 may also adopt other conventional displacement drive mechanisms in the art, such as hydraulic cylinders, motor screw nuts, electric telescopic rods, linear motors, etc., which can achieve the effect of this embodiment.
