[0042] See Figure 1 , Figure 1 A structural schematic diagram of a battery conveying device in an embodiment of the present invention is shown. The battery conveying device provided in an embodiment of the present invention includes a conveying assembly and a tray assembly 104; the conveying assembly is used to drive the tray assembly 104 to perform a circular motion; the tray assembly 104 is arranged on the conveying assembly, and the tray assembly 104 includes a limiting assembly, and the position of the limiting assembly on the tray assembly 104 can be adjusted to form a battery accommodating slot 106 with adjustable size.

[0043] Specifically, the tray assembly 104 is disposed on the conveyor assembly. A limiting assembly is provided on the tray assembly 104. The limiting assembly can adjust the position of the tray assembly 104 along a first direction and a second direction. A battery receiving slot 106 is formed between the limiting assemblies. The size of the battery receiving slot 106 can be adjusted according to the size of the battery and limits the position of the battery on the conveyor assembly.

On the other hand, the battery tray assembly is fixed on the conveying assembly, so that the battery tray can follow the conveying assembly for circular motion. After the battery is transferred, there is no need to remove the battery tray, and the battery tray can be recycled, thereby improving the utilization efficiency of the battery tray and the conveying efficiency of the battery conveying device.

[0045] Combine Figure 2 As shown, Figure 2 A schematic diagram of the structure of a tray assembly according to one embodiment of the present invention is shown. In some embodiments, the positioning assembly includes a first positioning member 108 and a second positioning member 110 disposed opposite each other in a first direction, and / or a third positioning member 112 and a fourth positioning member 114 disposed opposite each other in a second direction. The tray assembly 104 includes a first mounting plate 116, a second mounting plate 118, and a third mounting plate 120. The first mounting plate 116 is configured to support the third positioning member 112 and the fourth positioning member 114. The third positioning member 112 and the fourth positioning member 114 are disposed at first and second ends of the first mounting plate 116 in the second direction, respectively. The second mounting plate 118 is configured to support the first positioning member 108. The third mounting plate 120 is configured to support the second positioning member 110. The second mounting plate 118 and the third mounting plate 120 are symmetrical with respect to the first mounting plate 116 in the first direction. The first, second, and third mounting plates 116, 118, 120 are spaced apart from each other on the conveyor assembly and circulate therewith.

[0046] Illustratively, the first mounting plate 116, the second mounting plate 118, and the third mounting plate 120 are rectangular parallelepipeds; the second mounting plate 118, the first mounting plate 116, and the third mounting plate 120 are spaced apart along the first direction on the conveying assembly; the second mounting plate 118 and the third mounting plate 120 are symmetrical with respect to the first mounting plate 116. The first stopper 108 is disposed on the second mounting plate 118, and the second stopper 110 is disposed on the third mounting plate 120. The first stopper 108 and the second stopper 110 are symmetrically disposed with respect to the first mounting plate 116 in the first direction; the third stopper 112 and the fourth stopper 114 are disposed at the first end and the second end of the first mounting plate 116 in the second direction. Among them, by adjusting the distance between the first limiter 108 and the second limiter 110 to adapt to the sizes of different types of batteries in the first direction, and by adjusting the distance between the third limiter 112 and the fourth limiter 114 to adapt to the sizes of different types of batteries in the second direction, the limiter assembly and the first mounting plate 116, the second mounting plate 118, and the third mounting plate 120 together form a battery accommodating slot 106, and the size of the battery accommodating slot 106 can be adjusted by the limiter assembly.

[0047] Combine Figure 3 As shown, a fourth mounting plate 150 is provided between the first mounting plate 116 and the second mounting plate 118, and a fifth mounting plate 152 is provided between the first mounting plate 116 and the third mounting plate 120. This increases the spacing between the first and second stoppers in the first direction, allowing the battery receiving slot 106 to accommodate larger batteries. Optionally, two or more mounting plates may be provided between the first mounting plate 116 and the second mounting plate 118, and between the first mounting plate 116 and the third mounting plate 120.

[0048] Furthermore, the first mounting plate 116, the second mounting plate 118, and the third mounting plate 120 are each connected to the conveyor assembly, with a certain distance between each mounting plate. When the conveyor assembly circulates, there is a certain large-angle bending area in the conveyor assembly. Because the first mounting plate 116, the second mounting plate 118, and the third mounting plate 120 are independently arranged at a certain distance, they can pass through the large-angle bending area of ​​the conveyor assembly in sequence, thereby recycling the battery tray.

[0049] Optionally, the first mounting plate 116, the second mounting plate 118 and the third mounting plate 120 are made of a higher-strength material, such as a hard plastic plate or a lightweight metal plate (aluminum, aluminum alloy). There can be multiple second mounting plates 118 and third mounting plates 120, and the number of second mounting plates 118 and third mounting plates 120 is the same and symmetrical about the first mounting plate 116.

[0050] In this embodiment, a battery accommodating groove is formed by a limiting assembly, and the size of the battery accommodating groove is limited in the first direction and the second direction respectively, so as to accommodate batteries of different sizes and improve the applicability of the tray assembly; the first mounting plate, the second mounting plate and the third mounting plate are independently arranged at intervals, which is beneficial for the first mounting plate, the second mounting plate and the third mounting plate to be able to be smoothly flipped in the large-angle bending area of ​​the conveying assembly, thereby ensuring the smoothness of the conveying of the conveying assembly.

[0051] Please continue reading Figure 2 In some embodiments, the battery transfer device further includes a first adapter plate 122, a second adapter plate 124, and a third adapter plate 126. The first mounting plate 116 is movably connected to the first adapter plate 122, the second mounting plate 118 is movably connected to the second adapter plate 124, and the third mounting plate 120 is movably connected to the third adapter plate 126. The second adapter plate 124 and the third adapter plate 126 move along the second direction on the second mounting plate 118 and the third mounting plate 120, respectively.

[0052] A first protrusion 128 and a second protrusion 130 are formed on a surface of the first adapter plate 122 away from the first mounting plate 116. The first protrusion 128 and the second protrusion 130 are disposed at opposite ends of the first mounting plate 116 and are U-shaped. The third and fourth limiting members 112 and 114 are movably disposed in a channel formed by the first and second protrusions 128 and 130. The third and fourth limiting members 112 and 114 can be adjusted along a first direction within the channel and are fixed at corresponding positions within the channel based on the size of the battery.

[0053] Optionally, a third protrusion 132 and a fourth protrusion 134 are further provided on the first adapter plate 122. The third protrusion 132 and the fourth protrusion 134 are respectively arranged along opposite sides of the first adapter plate 122, and form a channel with the first protrusion 128 and the second protrusion 130 to prevent the third limiter 112 and the fourth limiter 114 from falling when adjusting in the channel; they can also provide support for the battery to prevent the battery from being suspended in the first direction.

[0054] Furthermore, a first recess 136 is provided on a side of the second adapter plate 124 away from the second mounting plate 118; the first recess 136 opens toward the first mounting plate 116, and is used to adjust the position of the first limit member 108 in the first direction, and enable the first limit member 108 to move along the first direction within the first boss; a second recess 138 is provided on a side of the third adapter plate 126 away from the third mounting plate 120; the second recess 138 opens toward the first mounting plate 116, and is used to adjust the position of the second limit member 110 in the first direction, and enable the second limit member 110 to move along the first direction within the second boss.

[0055] For example, the second mounting plate 118, the first mounting plate 116, and the third mounting plate 120 are arranged in sequence along the first direction. A second adapter plate 124 is provided on the second mounting plate 118. The second adapter plate 124 is clamped onto the second mounting plate 118 and can be moved and adjusted along the second direction on the second mounting plate 118. The first stopper 108 is inserted into the second adapter plate 124 along the opening of the first recessed platform 136 and can be moved and adjusted along the first direction within the first recessed platform 136. At the same time, the second adapter plate 124 is clamped onto the second mounting plate 118 and can move along the second direction on the second mounting plate 118. At this time, the first stopper 108 can achieve movement and adjustment in the first direction and the second direction, respectively. The third mounting plate 120 is provided with a third adapter plate 126, which is clamped on the third mounting plate 120 and can move along the second direction on the third mounting plate 120; the second limiting member 110 is inserted into the third adapter plate 126 along the opening of the second recessed platform 138, and is moved and adjusted along the first direction within the second recessed platform 138; at the same time, the third adapter plate 126 is clamped on the third mounting plate 120, and the third adapter plate 126 can be moved and adjusted along the second direction on the third mounting plate 120, at this time, the second limiting member 110 can realize movement and adjustment in the first direction and the second direction respectively.

[0056] Optionally, when there are multiple second mounting plates 118 and multiple third mounting plates 120 , the second adapter plate 124 and the third adapter plate 126 can be symmetrically arranged on different second mounting plates 118 and third mounting plates 120 .

[0057] In this embodiment, the position of the limit assembly on the first mounting plate, the second mounting plate and the third mounting plate is adjusted through the first adapter plate, the second adapter plate and the third adapter plate, providing a larger adjustment space in the first direction and the second direction, so that the battery accommodating slot can accommodate batteries of different sizes, thereby improving the use range of the tray assembly.

[0058] Please continue reading Figure 2 and combined Figure 4 , Figure 4 FIG. 1 shows a schematic structural diagram of a battery conveyor according to an embodiment of the present invention. In some embodiments, the battery conveyor further includes a control system for controlling the movement and stopping of the conveyor assembly. The control system includes a sensing element 146 and a signal element 148.

[0059] Specifically, the conveyor assembly includes a mounting bracket 140, a conveyor belt 142, and a rotating member 144. The mounting bracket 140 is used to support the conveyor belt 142 and the rotating member 144. The conveyor belt 142 is mounted on the mounting bracket 140. The first mounting plate 116, the second mounting plate 118, and the third mounting plate 120 are fixed to the conveyor belt 142. The rotating member 144 is connected to the conveyor belt 142 to drive the conveyor belt 142 in a circular motion. The sensor 146 is provided on the tray assembly 104 to receive and feedback the signal transmitted by the signal member 148. The signal member 148 is provided on the conveyor assembly to control the operating status of the conveyor assembly based on the signal feedback from the sensor 146.

[0060] Exemplarily, the conveyor belt 142 is mounted on the mounting bracket 140, the rotating member 144 is fixed to the mounting bracket 140 and drives the conveyor belt 142 to rotate, the sensing member 146 is disposed on the tray assembly 104, and the signal member 148 is disposed on the mounting bracket 140. The rotating member 144, the sensing member 146, and the signal member 148 are all electrically connected to a control system. The signal member 148 can be an infrared sensor that emits infrared light. When the infrared light hits the sensing member 146, the sensing member 146 reflects the infrared light back to the signal member 148. The signal member 148 receives the infrared light and determines whether the battery tray has reached the required position. If so, the control system outputs a control signal to the rotating member 144, causing the rotating member 144 to stop or move as required, thereby driving the conveyor belt 142, the tray assembly 104, and the battery to stop moving or continue moving in the first direction.

[0061] In this embodiment, by setting the sensing part on the tray assembly and the signal part on the transmission assembly, the position of the tray assembly is accurately obtained, and the control system comprehensively controls the movement state of the rotating part, thereby achieving precise stopping and positioning of the battery at any position or workstation.

[0062] In some embodiments, the battery sorting machine provided by the present invention includes a battery conveying device as in any other embodiment.
