[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. 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. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0038] refer to Figures 1 to 3 In one embodiment of the present application, a carrier conveying device is disclosed, including a first conveyor line 21, a second conveyor line 22, a first lifting and transferring mechanism 23, and a second lifting and transferring mechanism, wherein the first conveyor line 21 and the second conveyor line 22 are stacked up and down, and the conveying directions are opposite; the first lifting and transferring mechanism 23 connects the head end of the first conveyor line 21 and the end of the second conveyor line 22; the second lifting and transferring mechanism connects the head end of the second conveyor line 22 and the end of the first conveyor line 21 to form a circulatory transmission loop.

[0039] The above-mentioned transmission loop is used to transmit the carrier tray 28, and the carrier tray 28 circulates continuously in the above-mentioned transmission loop, and the carrier tray 28 has a positioning pin 281 for fixing the carrier. In some embodiments, the number of the positioning pins 281 is at least 2, which are respectively distributed at both ends of the carrier tray 28 and are used to fix the carrier. The carrier has a positioning hole that matches the positioning pin (the structure of the carrier refers to Figure 4 In the figure, at the carrier loading line 251, the carrier is located at the front end of the transmission direction of the carrier loading line 251).

[0040] refer to Figure 3 and Figure 5 A carrier loading and unloading mechanism 25 is provided on one side of the first conveyor line 21, including a carrier unloading line 252 for transferring damaged carriers for unloading, a carrier loading line 251 for transferring good carriers, and a carrier transfer platform 252 for transporting carriers.

[0041] Among them, the carrier transfer platform 252 can unload the damaged carrier from the first conveyor line 21 and transport it to the carrier unloading line 252 for unloading, and transport the finished carrier from the carrier loading line 251 to the first conveyor line 21 for loading.

[0042] And, a carrier detection sensor 29 for detecting whether there is a carrier on the carrier pallet. The carrier detection sensor 29 is located on the first conveyor line 21 and is arranged toward the carrier pallet 28. The carrier is detected when the carrier transfer platform 252 unloads or loads the carrier from the carrier pallet 28.

[0043] refer to Figure 2 and Figure 5 In order to efficiently and quickly transport the carrier, in some embodiments of the present application, the carrier transfer platform includes a clamp 254 for grabbing the carrier, a clamp lifting mechanism 255 for controlling the lifting of the clamp 254, a translation mechanism 256 for driving the clamp 254 to move between the carrier loading line 251 and the carrier unloading line 252, and a rotation mechanism 257 for driving the clamp 254 to transfer the carrier between the first conveyor line 21 and the carrier transfer platform 25. The clamp 254 is located on the rotation mechanism 257, the rotation mechanism 257 is connected to the clamp lifting mechanism 255, and the clamp lifting mechanism 255 is connected to the translation mechanism 256.

[0044] In order to facilitate the transmission of the carrier between the first conveyor line 21 and the carrier transfer platform 25, the rotating mechanism 257 includes a rotating cylinder 258 and a clamp mounting frame 259. The clamp 254 is connected to the clamp mounting frame 259. The clamp mounting frame 259 rotates with the rotating cylinder 258 to form a first position 26 and a second position 27. The first position 26 corresponds to the first conveyor line, and the second position 27 corresponds to the carrier loading line and the carrier unloading line. By extending the arm length of the clamp mounting frame 259 and combining the rotation of the rotating cylinder 258, the clamp 254 can be switched above the first conveyor line and the carrier loading line and the carrier unloading line by rotating the rotating cylinder 258. The method of rotating the position switching can further simplify the structure.

[0045] Furthermore, the rotation angle of the rotating cylinder 258 is 180°, and two clamps 254 are arranged on the clamp mounting frame 259, and the clamps 254 are arranged along the length direction of the clamp mounting frame 259, thereby fully utilizing the arm length of the clamp mounting frame 259, so that after the rotating cylinder 258 rotates, there are still clamps 254 at the first position and the second position that can be clamped, thereby fully utilizing the space advantage and improving the clamping efficiency of the clamps 254.

[0046] refer to Figure 4 In order to maintain stable transmission of the carrier pallet 28, in some embodiments of the present application, the first conveyor line 21 includes two parallel carrier rails 215 and a first transmission mechanism for driving the carrier pallet to move on the carrier rails.

[0047] Among them, the first transmission mechanism includes a telescopic cylinder 211, a transmission guide rail 212, a driving seat 213, and a plurality of locking members 214. The transmission guide rail 212 is arranged in parallel with the carrier guide rail 215, and the driving seat 213 slides along the transmission guide rail 212. The locking members 214 are arranged on the driving seat 213 and are evenly spaced. The telescopic cylinder 211 acts on the driving seat 213 to make reciprocating motion on the transmission guide rail 212. The locking members 214 lock the carrier pallet 28 when the telescopic cylinder 211 is extended, and release the carrier pallet 28 when the telescopic cylinder 211 is retracted.

[0048] In some embodiments, the stroke of the telescopic cylinder 211 is equal to the spacing between two adjacent locking members 214. When the telescopic cylinder 211 completes an extension process, each locking member 214 drives the carrier tray 28 to advance one station downstream, and when the telescopic cylinder 211 performs a retraction process, the locking member 214 returns to the previous station to lock the carrier tray 28 on the previous station. By adopting this transmission method to transmit the carrier tray 28, the transmission distance of the carrier tray 28 is more controllable, and the subsequent positioning steps of the carrier tray 28 can be reduced.

[0049] Furthermore, the stroke of the telescopic cylinder 211 is a multiple of the spacing between two adjacent locking members 214 .

[0050] refer to Figure 4 At the locking piece 214, the locking piece 214 and the carrier pallet are locked by a plug-in structure controlled by a cylinder. The carrier pallet 28 is provided with a locking piece, and a slot is provided on the locking piece for cooperating with the locking piece 214 for locking, thereby driving the carrier pallet 28 to move along the carrier guide rail 215.

[0051] Furthermore, the first conveyor line includes two carrier rails arranged in parallel, and a transmission belt structure for driving the carrier pallet to move on the carrier rails.

[0052] In this embodiment, the structure of the second lifting and transferring mechanism is the same as that of the first lifting and transferring mechanism 23 . The first lifting and transferring mechanism 23 includes a lifting platform and a pair of parallel guide rails on the lifting platform, which are used to dock with the carrier guide rails 215 .

[0053] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0054] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
