[0031] like Figure 1 、 2 As shown, the utility model provides a tray conveyor line, including a first tray conveyor line 100, a second tray conveyor line 200 and a tray transfer device 300; the first tray conveyor line 100 and the second tray conveyor line 200 are parallel and spaced apart, and the transport directions of the first tray conveyor line 100 and the second tray conveyor line 200 are opposite; the tray transfer device 300 includes a first drive mechanism 301 and a third tray conveyor line 302; the first drive mechanism 301 is used to drive the third tray conveyor line 302 to move, so that the third tray conveyor line 302 switches between the discharge end of the first tray conveyor line 100 and the feed end of the second tray conveyor line 200; the third tray conveyor line 302 is used to transfer the tray that has left the discharge end of the first tray conveyor line 100 to the feed end of the second tray conveyor line 200.

[0032] Specifically, if Figure 1 、 2As shown, the first tray conveyor line 100 and the second tray conveyor line 200 are arranged parallel to each other along the Y-axis, and both extend along the X-axis, wherein the transport direction of the first tray conveyor line 100 is to the right, and the transport direction of the second tray conveyor line 200 is to the left; the tray transfer device 300 is arranged on one side of the first tray conveyor line 100 and the second tray conveyor line 200 in the X-axis direction, for example, on the right side, that is, the first tray conveyor line 100, the tray transfer device 300 and the second tray conveyor line 200 form a U-shape as a whole. The tray transfer device 300 includes a first drive mechanism 301 and a third tray conveyor line 302; the tray load-bearing surfaces of the first tray conveyor line 100, the second tray conveyor line 200 and the third tray conveyor line 302 are at the same height, and the vertical distance between the third tray conveyor line 302 and the first tray conveyor line 100 and the second tray conveyor line 200 in the X-axis direction is in the range of 1 cm to 3 cm; the first drive mechanism 301 is used to drive the third tray conveyor line 302 to move along the Y-axis direction so that the third tray conveyor line 302 switches between the discharge end of the first tray conveyor line 100 and the feed end of the second tray conveyor line 200. It should be noted that "switching" here means that the third tray conveyor line 302 can choose to stop at the discharge end of the first tray conveyor line 100 or the feed end of the second tray conveyor line 200.

[0033] In this embodiment, when the tray conveyor line is used, the first tray conveyor line 100 can be used as a loading tray conveyor line, and the second tray conveyor line 200 can be used as an empty tray return line; after the loaded tray is unloaded from the first tray conveyor line 100, the first tray conveyor line 100 will drive the empty tray to move toward the discharge end of the first tray conveyor line 100 until the tray is separated from the discharge end of the first tray conveyor line 100 and transported to the third tray conveyor line 302. At this time, the first drive mechanism 301 is used to drive the third tray conveyor line 302 to move to the feed end of the second tray conveyor line 200, and then the third tray conveyor line 302 and the second tray conveyor line 200 work. The third tray conveyor line 302 can convey the tray to the second tray conveyor line 200 and return it by the second tray conveyor line 200. In summary, compared with manual transfer of trays, the tray conveyor line of the present invention can improve the rotation efficiency of the trays on the production line.

[0034] Optionally, when the third tray conveyor line 302 is located at the output end of the first tray conveyor line 100, the transport direction of the third tray conveyor line 302 is the same as that of the first tray conveyor line 100; when the third tray conveyor line 302 is located at the input end of the second tray conveyor line 200, the transport direction of the third tray conveyor line 302 is the same as that of the second tray conveyor line 200.

[0035] Specifically, the third tray conveyor line 302 is a bidirectional conveyor line, that is, the transport direction of the third tray conveyor line 302 is adjustable. For example, when the third tray conveyor line 302 is located at the output end of the first tray conveyor line 100, the third tray conveyor line 302 and the first tray conveyor line 100 have the same transport direction, and the first tray conveyor line 100 and the third tray conveyor line 302 jointly apply force to reduce the time it takes for trays above the first tray conveyor line 100 to be transported to the third tray conveyor line 302. Similarly, when the third tray conveyor line 302 is located at the input end of the second tray conveyor line 200, the third tray conveyor line 302 and the second tray conveyor line 200 have the same transport direction, and the second tray conveyor line 200 and the third tray conveyor line 302 jointly apply force to reduce the time it takes for trays above the third tray conveyor line 302 to be transported to the second tray conveyor line 200.

[0036] Optionally, the first driving mechanism 301 includes a first track 3011, a first power device 3012 and a sliding block 3013; the sliding block 3013 is slidably set on the first track 3011, the third material tray conveyor line 302 is set on the sliding block 3013, and the first power device 3012 is used to drive the third material tray conveyor line 302 to move along the first track 3011 through the sliding block 3013.

[0037] Specifically, if Figure 3 As shown, the first track 3011 extends along the Y-axis, the sliding block 3013 is slidably disposed above the first track 3011, and the third tray conveyor line 302 is disposed on the upper end surface of the sliding block 3013. The first power unit 3012 is a drive motor, which is connected to the sliding block 3013 via a lead screw. In other words, the first drive mechanism 301 can be considered a linear module.

[0038] In other embodiments, the first power device 3012 can be a telescopic cylinder, which is connected to the sliding block 3013 to drive the sliding block 3013 to move on the first track 3011; the first power device 3012 can also be a double winch, and the two winches pull the sliding block 3013 back and forth through ropes to move on the first track 3011.

[0039] In this optional embodiment, when the first driving mechanism 301 is working, the first power device 3012 is started, which can drive the third tray conveyor line 302 to move along the first track 3011 through the sliding block 3013. Due to the existence of the first track 3011, during the movement of the third tray conveyor line 302, the displacement of the third tray conveyor line 302 in the X-axis direction can be limited, thereby reducing the probability of the third tray conveyor line 302 being deflected.

[0040] Optionally, the third tray conveyor line 302 includes a first mounting frame 3021, a first belt conveyor mechanism 3022, a second belt conveyor mechanism 3023 and a second driving mechanism 3024; the first mounting frame 3021 is connected to the sliding block 3013; the first belt conveyor mechanism 3022 and the second belt conveyor mechanism 3023 are parallel and spaced apart from each other on the first mounting frame 3021, and the second driving mechanism 3024 is used to drive the first belt conveyor mechanism 3022 and the second belt conveyor mechanism 3023 to move synchronously.

[0041] Specifically, if Figure 4 、 5 As shown, the first mounting frame 3021 is connected to the sliding block 3013, and the connection method between the two includes but is not limited to screw connection, snap connection or plug-in connection, which is not limited here and depends on actual needs; the first belt conveyor mechanism 3022 and the second belt conveyor mechanism 3023 are arranged parallel to and spaced apart from the first mounting frame 3021, and the spacing between the two is not limited and depends on actual needs; the second driving mechanism 3024 can drive the first belt conveyor mechanism 3022 and the second belt conveyor mechanism 3023 to move synchronously.

[0042] In this optional embodiment, when the empty tray is transported to the third tray conveyor line 302, the first belt conveyor mechanism 3022 and the second belt conveyor mechanism 3023 are respectively used to support the opposite ends of the bottom of the tray. At this time, if the second drive mechanism 3024 is working, the second drive mechanism 3024 can drive the first belt conveyor mechanism 3022 and the second belt conveyor mechanism 3023 to move synchronously, thereby driving the tray to move relative to the first mounting frame 3021.

[0043] Optionally, the first mounting frame 3021 includes a first connecting plate 30213 and a first mounting plate 30211 and a second mounting plate 30212 that are opposite to and spaced apart from each other at the upper end of the first connecting plate 30213; the first connecting plate 30213 is connected to the sliding block 3013; a first mounting space is formed between the first mounting plate 30211 and the second mounting plate 30212, and the first belt conveyor mechanism 3022 and the second belt conveyor mechanism 3023 are arranged at the same height in the first mounting space.

[0044] Specifically, if Figure 4 、 5As shown, the first mounting plate 30211 and the second mounting plate 30212 are rectangular plates, which are opposite to each other and spaced apart at the upper end of the first connecting plate 30213, wherein a first mounting space is formed between the first mounting plate 30211 and the second mounting plate 30212, and the first belt conveyor mechanism 3022 and the second belt conveyor mechanism 3023 are arranged at the same height in the first mounting space.

[0045] In this optional embodiment, the first belt conveyor mechanism 3022 and the second belt conveyor mechanism 3023 are arranged at the same height in the first installation space, which can effectively reduce the probability of collision between the first belt conveyor mechanism 3022 and the second belt conveyor mechanism 3023 during transportation or installation, and play a role in protecting the first belt conveyor mechanism 3022 and the second belt conveyor mechanism 3023.

[0046] Optionally, the top surfaces of the first mounting plate 30211 and the second mounting plate 30212 are both higher than the tray load-bearing surface of the first belt conveyor mechanism 3022 and the tray load-bearing surface of the second belt conveyor mechanism 3023 .

[0047] Specifically, if Figure 4 、 5 As shown, the top surfaces of the first mounting plate 30211 and the second mounting plate 30212 are at the same height, and the top surfaces of both are 1 cm to 3 cm higher than the material tray bearing surface of the first belt conveyor mechanism 3022 and the material tray bearing surface of the second belt conveyor mechanism 3023.

[0048] In this optional embodiment, when the tray load-bearing surface of the first belt conveyor mechanism 3022 and the tray load-bearing surface of the first belt conveyor mechanism 3022 support the tray, the end surfaces of the first mounting plate 30211 and the second mounting plate 30212 facing each other can serve the purpose of limiting the displacement of the tray in the Y-axis direction.

[0049] Optionally, the second driving mechanism 3024 includes a second power device 30241 and a first connecting rod 30242; the first belt conveyor mechanism 3022 includes at least two first rollers 30221 and a first belt 30222 arranged around all the first rollers 30221; the second belt conveyor mechanism 3023 includes at least two second rollers 30231 and a second belt 30232 arranged around all the second rollers 30231; at least one first roller 30221 and one second roller 30231 are connected to form a roller structure through the first connecting rod 30242, and the second power device 30241 is used to drive the roller structure to rotate relative to the first mounting frame 3021.

[0051] In this optional embodiment, when the second power device 30241 is working, it can drive the roller structure to rotate relative to the first mounting frame 3021, that is, the first roller 30221 in the roller structure can rotate relative to the first mounting plate 30211, and the second roller 30231 in the roller structure can rotate relative to the second mounting plate 30212. At this time, the first roller 30221 can drive the first belt 30222 to perform reciprocating motion, and the second roller 30231 can drive the second belt 30232 to perform reciprocating motion, thereby realizing the movement of the material tray on the third material tray conveyor line 302.

[0052] Furthermore, the circumference of the first roller 30221 and the inner wall of the first belt 30222 are respectively provided with latch teeth, and the first roller 30221 and the first belt 30222 can be driven by engaging with the latch teeth, thereby reducing the probability of the first roller 30221 and the first belt 30222 slipping; similarly, the circumference of the second roller 30231 and the inner wall of the second belt 30232 are respectively provided with latch teeth, and the second roller 30231 and the second belt 30232 can be driven by engaging with the latch teeth, thereby reducing the probability of the second roller 30231 and the second belt 30232 slipping.

[0053] In other embodiments, the second driving mechanism 3024 may not have a roller structure, that is, the first roller 30221 and the second roller 30231 are not connected by the first connecting rod 30242. In this case, the second power device 30241 includes two driving motors, and the two driving motors respectively drive the first roller 30221 and the second roller 30231 to rotate.

[0054] Optionally, the first belt conveyor mechanism 3022 further includes a first support block 30223; the first support block 30223 is arranged in the annular space surrounded by the first belt 30222, and supports the inner top surface of the first belt 30222; and / or, the second belt conveyor mechanism 3023 further includes a second support block 30233; the second support block 30233 is arranged in the annular space surrounded by the second belt 30232, and supports the inner top surface of the second belt 30232.

[0055] Specifically, if Figure 4 、 5 As shown, the shape of the first support block 30223 is similar to a rectangle, and it is fixedly connected to the first mounting plate 30211; the first support block 30223 is located in the annular space surrounded by the first belt 30222, and supports the inner top surface of the first belt 30222; the shape of the second support block 30233 is similar to a rectangle, and it is fixedly connected to the second mounting plate 30212; the second support block 30233 is located in the annular space surrounded by the second belt 30232, and supports the inner top surface of the second belt 30232.

[0058] It should be noted that the feed end of the third tray conveyor line 302 and the discharge end of the third tray conveyor line 302 of this embodiment can be converted into each other according to the working state of the third tray conveyor line 302. For example, when the third tray conveyor line 302 is located at the discharge end of the first tray conveyor line 100, the end of the third tray conveyor line 302 facing the first tray conveyor line 100 is the feed end of the third tray conveyor line 302, and the end of the third tray conveyor line 302 away from the first tray conveyor line 100 is the discharge end of the third tray conveyor line 302; when the third tray conveyor line 302 is located at the feed end of the second tray conveyor line 200, the end of the third tray conveyor line 302 facing the second tray conveyor line 200 is the discharge end of the third tray conveyor line 302, and the end of the third tray conveyor line 302 away from the second tray conveyor line 200 is the feed end of the third tray conveyor line 302.
