[0001] This application belongs to the field of conveying technology, and more specifically, relates to a reversing conveying mechanism and a circulating conveying device. Background Technology

[0002] During the production or testing process, products need to be transported by conveying devices. Since products often need to be transported in different directions, it is necessary to change the transport direction of the products. The existing technology has a relatively complex structure for changing the transport direction of products. Utility Model Content

[0003] The purpose of this application is to provide a reversing conveying mechanism and a circulating conveying device to solve the technical problem that the structure for changing the conveying direction is relatively complex in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: Firstly, a reversing conveying mechanism is provided, comprising a frame, a first conveying component, a second conveying component, and a lifting component. The second conveying component, the first conveying component, and the lifting component are disposed on the frame. The second conveying component is disposed at at least one end of the first conveying component along a second direction. The output end of the lifting component is connected to the second conveying component to drive at least a conveying portion of the second conveying component to rise or fall. The first conveying component is used to convey material to the second conveying component along the second direction, and the lifting component is used to drive the second conveying component to rise, so that the second conveying component can convey the material along a first direction. The second direction is perpendicular to the first direction.

[0005] In some embodiments, the reversing conveying mechanism includes a plurality of first conveying components arranged at intervals along the second direction and a plurality of second conveying components arranged at intervals along the second direction, wherein each second conveying component is disposed between two adjacent first conveying components along the second direction.

[0006] In some embodiments, the reversing conveyor mechanism further includes a material arrival sensor for detecting whether the first conveying component is conveying the material above the second conveying component.

[0007] In some embodiments, the reversing conveying mechanism includes a first end and a second end disposed opposite to each other along the second direction, a plurality of first conveying components are sequentially spaced between the first end and the second end and are used to convey the material from the first end to the second end; the second end is provided with a baffle, and the material arrival sensor is spaced apart from the baffle along the second direction.

[0008] In some embodiments, the second conveying assembly is a belt conveying assembly, which includes a mounting frame, a belt drive mounted on the mounting frame, two pulleys rotatably mounted on the mounting frame, and a belt wound around the two pulleys.

[0009] In some embodiments, the reversing conveyor mechanism includes a plurality of belt conveyor assemblies spaced apart, each belt conveyor assembly including a drive wheel, the frame having a connecting shaft, each drive wheel being installed at a different position on the connecting shaft, and one of the drive wheels being connected to the output end of the belt drive.

[0010] In some embodiments, the belt conveyor assembly further includes two guide wheels, which are respectively mounted on the mounting frame and located on opposite sides of the drive wheel, and the belt is respectively wound around the drive wheel, the two guide wheels and the two pulleys.

[0011] In some embodiments, the output end of the lifting assembly is provided with a lifting frame, and each of the second conveying components is installed at a different position on the lifting frame. The lifting assembly is used to drive each of the second conveying components to move up and down synchronously through the lifting frame.

[0012] In some embodiments, the reversing conveying mechanism includes two sets of lifting components, which are respectively disposed at opposite ends of the second conveying component. One set of lifting components is used to synchronously drive one end of each of the second conveying components to rise and fall synchronously, and the other set of lifting components is used to synchronously drive the other end of each of the second conveying components to rise and fall synchronously.

[0013] In some embodiments, the lifting assembly includes: The base is mounted on the frame; A lifting drive component is installed on the base, and the output end of the lifting drive component is connected to the second conveying assembly; Guide rod, one end of which is connected to the second conveying assembly; A linear bearing is mounted on the base, and the other end of the guide rod is connected to the linear bearing.

The axle of each roller conveying assembly is connected to the output end of the roller drive through the synchronizing element, and the roller drive drives each axle to rotate synchronously through the synchronizing element. Secondly, this application also provides a circulating conveying device, including the aforementioned reversing conveying mechanism.

[0016] The beneficial effects of the reversing conveying mechanism and circulating conveying device provided in this application are as follows: By setting the second conveying component at at least one end of the first conveying component along the second direction, and providing a lifting component capable of driving the second conveying component to rise and fall, the second conveying component is lowered to avoid obstructing the material conveying along the second direction when material is conveyed through the first conveying component along the second direction. Furthermore, when material is conveyed to the second conveying component, the lifting component drives the second conveying component to rise, so that the second conveying component supports the material and conveys it along the first direction, thereby changing the conveying direction from the second direction to conveying along the first direction. Overall, the reversing conveying mechanism of this application not only realizes the reversing conveying of materials, but also has a simple structure and occupies little space, making its application range wider.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0024] Firstly, please refer to Figure 1 The circulating conveyor device 1 provided in the embodiments of this application will now be described. This circulating conveyor device 1 is used to circulate materials for operating equipment. For example, in this embodiment, the circulating conveyor device 1 circulates circuit boards to the optical inspection equipment 2 to simulate the continuous inspection of circuit boards by the optical inspection equipment 2 on a customer's on-site production line. It is understood that in other embodiments of this application, the circulating conveyor device 1 can also be used to circulate materials for other equipment, such as processing equipment or other inspection equipment.

[0025] Please see Figure 1 The circulating conveying device 1 includes an input end 300 for feeding materials into the working equipment and an output end 400 for receiving materials output from the working equipment. At least one linear conveying mechanism 200 and at least two reversing conveying mechanisms 100 are provided between the input end 300 and the output end 400. The linear conveying mechanism 200 is connected between the two reversing conveying mechanisms 100 or between the reversing conveying mechanism 100 and the working equipment. The reversing conveying mechanism 100 is located at the corner position of the circulating conveying device 1 to realize reversing conveying.

[0026] In practical applications, the input end 300 of the circulating conveyor 1 can be connected to the inlet of the working equipment, and the output end 400 of the circulating conveyor 1 can be connected to the outlet of the working equipment. The material is conveyed from the output end 400 to the input end 300 through the linear conveyor 200 and the reversing conveyor 100 respectively (specifically, when encountering a straight position, it is conveyed through the linear conveyor 200, and when encountering a corner position, it is reversing the conveying through the reversing conveyor 100), and then conveyed to the working equipment through the input end 300. After being processed by the working equipment (e.g., for detection), the material is conveyed from the output end 400 in this way, so that the material can be circulated into the working equipment for processing.

[0027] The circulating conveying device 1 in this embodiment of the application is provided with an input end 300 for inputting materials into the working equipment and an output end 400 for receiving materials output from the working equipment. At least one linear conveying mechanism 200 and at least two reversing conveying mechanisms 100 are provided between the input end 300 and the output end 400. During the material conveying process, when encountering a straight position, the material is conveyed by the linear conveying mechanism 200, and when encountering a corner position, the material is reversed by the reversing conveying mechanism 100. This allows the circulating conveying device 1 to circulate materials to the working equipment, thereby simulating the assembly line situation of the working equipment in the actual field. For example, it can simulate the continuous inspection of the circuit board by the optical inspection equipment 2 in the case of a complete line, thereby effectively testing the performance of the equipment and improving the customer experience.

[0028] In this application, the number of reversing conveying mechanisms 100 in the circulating conveying device 1 may vary depending on the actual conveying direction of the materials inside the working equipment, as illustrated below.

[0029] In some embodiments, please refer to Figure 1 The circulating conveying device 1 includes four reversing conveying mechanisms 100, which are respectively located at the four corner positions of the circulating conveying device 1 to realize reversing conveying.

[0030] Specifically, in this embodiment, the inlet and outlet of the working equipment are arranged opposite each other along the first direction X. Four reversing conveyor mechanisms 100 are respectively located at the four corners of a rectangle. The working equipment and the linear conveyor mechanism 200 are arranged opposite each other and located at one of the long sides. The linear conveyor mechanism 200 conveys materials along the first direction X. The reversing conveyor mechanism 100 is used to realize the reversal from the first direction X to the second direction Y, or to realize the reversal from the second direction Y to the first direction X. The first direction X and the second direction Y are perpendicular to each other.

[0031] In this embodiment, four reversing conveyor mechanisms 100 are provided to meet the requirement that the inlet and outlet of the working equipment are arranged opposite each other along the first direction X. It can be understood that in other embodiments of this application, when the inlet and outlet of the working equipment are located on adjacent sides, three reversing conveyor mechanisms 100 can be provided; or when the material in the working equipment is fed and discharged from the same side, two reversing conveyor mechanisms 100 can be provided.

[0032] In some embodiments, please refer to Figure 1 The linear conveyor 200 conveys materials along the first direction X. The linear conveyor 200 and the working equipment are spaced apart along the second direction Y. Two reversing conveyors 100 are interconnected and connected between the input end 300 and one end of the linear conveyor 200. The other two reversing conveyors 100 are interconnected and connected between the output end 400 and the other end of the linear conveyor 200.

[0033] In this embodiment, two reversing conveying mechanisms 100 located between one end of the linear conveying mechanism 200 and the input end 300 are directly connected to reduce the conveying distance of the linear conveying mechanism 200 and the input end 300 along the second direction Y; and two reversing conveying mechanisms 100 located between the other end of the linear conveying mechanism 200 and the output end 400 are directly connected to reduce the conveying distance of the linear conveying mechanism 200 and the output end 400 along the second direction Y, thereby reducing the conveying distance of the entire circulating conveying device 1, thereby reducing the structural cost and space occupied by the circulating conveying device 1, and improving the circulating conveying efficiency.

[0034] In other embodiments of this application, the circulating conveying device 1 includes three linear conveying mechanisms 200, with each pair of adjacent reversing conveying mechanisms 100 connected by a linear conveying mechanism 200. For details, please refer to [link to specific embodiments]. Figure 2Four reversing conveyor mechanisms 100 are located at the four corners of the rectangle. Three linear conveyor mechanisms 200 are respectively the first linear conveyor mechanism 200a, the second linear conveyor mechanism 200b, and the third linear conveyor mechanism 200c. The first linear conveyor mechanism 200a conveys materials along the first direction X, and the first linear conveyor mechanism 200a and the working equipment are spaced apart along the second direction Y. Two of the reversing conveyor mechanisms 100 are connected between the input end 300 and one end of the first linear conveyor mechanism 200a, and the second linear conveyor mechanism 200b is connected between the two reversing conveyor mechanisms 100. The other two reversing conveyor mechanisms 100 are connected between the output end 400 and the other end of the first linear conveyor mechanism 200a, and the third linear conveyor mechanism 200c is connected between the two reversing conveyor mechanisms 100. In this embodiment, the arrangement of three linear conveying mechanisms 200 makes the space enclosed by the circulating conveying device 1 larger, so as to be able to circulate and transport more circuit boards, and also makes the structure of the reversing conveying mechanism 100 simpler (the position of the reversing conveying mechanism 100 will be explained later).

[0035] In some embodiments, a caster wheel assembly 500 for supporting materials is provided between the reversing conveyor mechanism 100 and the linear conveyor mechanism 200. The caster wheel assembly 500 is provided to support the materials to prevent them from sagging and jamming during transport between the two mechanisms, thereby ensuring that the materials can be smoothly transported through the caster wheel assembly 500 and improving the material conveying efficiency.

[0036] In some embodiments, please refer to Figure 4 Between two adjacent reversing conveyor mechanisms 100, a caster wheel assembly 500 is provided for supporting materials. The caster wheel assembly 500 is designed to support the materials to prevent them from sagging and jamming during transport between the two mechanisms, thus ensuring that the materials can be smoothly transported through the caster wheel assembly 500 and improving material conveying efficiency.

[0037] In some embodiments, a universal wheel assembly 500 for supporting materials is provided between the reversing conveyor 100 and the linear conveyor 200, and a universal wheel assembly 500 for supporting materials is provided between two adjacent reversing conveyors 100, thereby ensuring that the materials are transported smoothly throughout the entire circulating conveyor device 1, so as to improve the material conveying effect.

[0038] In some embodiments, please refer to Figure 4The caster assembly 500 includes at least one row of casters 510, and each row of casters 510 includes multiple casters 510 spaced apart. When material is conveyed above the casters 510, each caster 510 supports the material together, and the casters 510 can turn to reduce the friction between the casters 510 and the material and improve the material conveying efficiency.

[0039] Optionally, the caster assembly 500 includes two rows of casters 510, which are respectively mounted on the frames 110 of two adjacent mechanisms. For example, the two rows of casters 510 are respectively mounted on the frames 110 of two reversing conveyor mechanisms 100, or the two rows of casters 510 are respectively mounted on the frames 110 of the reversing conveyor mechanism 100 and the linear conveyor mechanism 200.

[0040] In some embodiments, the circulating conveying device 1 further includes a controller, and both the linear conveying mechanism 200 and the reversing conveying mechanism 100 are communicatively connected to the controller. The controller allows for the separate control of the linear conveying mechanism 200 and the reversing conveying mechanism 100, and the timing of their operation can be controlled according to the material conveying conditions, enabling the circulating conveying device 1 to automatically convey materials throughout the entire process.

[0041] In some embodiments, please refer to Figure 5 Both the linear conveyor 200 and the reversing conveyor 100 are equipped with independent control boxes 170. Operators can use the independent control boxes 170 to control the linear conveyor 200 and the reversing conveyor 100 to work independently, so as to facilitate on-site adjustment or maintenance by the operators.

[0042] In some embodiments, please refer to Figure 4 The circulating conveying device 1 also includes a controller. Both the linear conveying mechanism 200 and the reversing conveying mechanism 100 are communicatively connected to the controller, and both the linear conveying mechanism 200 and the reversing conveying mechanism 100 are equipped with independent control boxes 170. This allows for selection of fully automatic or manual control of the conveying process according to actual application requirements.

[0043] In some embodiments, please refer to Figure 1 The linear conveyor mechanism 200 and the reversing conveyor mechanism 100 are set separately. Specifically, the linear conveyor mechanism 200 and the reversing conveyor mechanism 100 are each set independently through their respective frames 110. This allows different numbers of linear conveyor mechanisms 200 and reversing conveyor mechanisms 100 to be spliced ​​together according to the needs of the application to form different circulating conveying devices 1, and facilitates the replacement and maintenance of the linear conveyor mechanism 200 and the reversing conveyor mechanism 100.

[0044] In some embodiments, please refer to Figure 1 The number of linear conveyor mechanisms 200 between two adjacent reversing conveyor mechanisms 100 can be one or more, depending on the distance between them. If the distance between the two reversing conveyor mechanisms 100 is large, two, three, or more linear conveyor mechanisms 200 can be set between them to make the size of a single linear conveyor mechanism 200 relatively small, facilitating modular design. When the distance between the two reversing conveyor mechanisms 100 is small, only one linear conveyor mechanism 200 can be set between them.

[0045] In some embodiments, please refer to Figure 1 and Figure 3 The linear conveyor mechanism 200 includes a base frame 240 and multiple wheel conveyor assemblies 210. Each wheel conveyor assembly 210 is installed on the base frame 240 and is arranged at intervals along the first direction X.

[0046] Specifically, the linear conveying mechanism 200 includes a wheel drive 220, a synchronization structure 230, and a plurality of wheel conveying assemblies 210 arranged sequentially at intervals. Each wheel conveying assembly 210 is connected to the wheel drive 220 through the synchronization structure 230. The wheel drive 220 is used to drive each wheel conveying assembly 210 to rotate synchronously through the synchronization structure 230 to convey materials.

[0047] The wheel conveyor assembly 210 includes a shaft 211 and multiple wheel pieces 212; the shaft 211 is rotatably mounted on the base frame 240, and each wheel piece 212 is fixedly sleeved on the shaft 211; the synchronization structure 230 includes multiple transmission wheels 231 and a driving member 232, each transmission wheel 231 is fixed to the shaft 211 of each wheel conveyor assembly 210; the driving member 232 is connected to the wheel drive member 220, and the driving member 232 is connected to each transmission wheel 231 in a transmission connection.

[0048] When the wheel drive 220 drives the drive 232, the drive 232 drives each transmission wheel 231 to rotate synchronously, thereby driving each shaft 211 to rotate synchronously, and then driving each wheel 212 to rotate synchronously, so as to convey materials along a straight line.

[0049] Optionally, the wheel drive 220 is used to output rotational motion, the driving element 232 is a chain, and each transmission wheel 231 is a sprocket. One of the sprockets is connected to the wheel drive 220. When the wheel drive 220 drives the sprocket to rotate, the chain causes all sprockets to rotate, thereby driving all shafts 211 to rotate. It is understood that in other embodiments of this application, the driving element 232 may also be a belt, and each transmission wheel 231 may be a pulley; or, the driving element 232 may be a rack and pinion, and each transmission wheel 231 may be a gear. This is not a unique limitation.

[0050] Optionally, please refer to Figure 3 Adjacent wheel pieces 212 are directly abutted by connecting sleeves 213.

[0051] Secondly, please refer to Figure 5 and Figure 6 The reversing conveying mechanism 100 provided in the embodiments of this application will now be described.

[0052] The reversing conveying mechanism 100 includes a frame 110, a first conveying component 120, a second conveying component 130, and a lifting component 140. The second conveying component 130, the first conveying component 120, and the lifting component 140 are disposed on the frame 110. The second conveying component 130 is disposed at at least one end of the first conveying component 120 along the second direction Y. The lifting component 140 is connected to the second conveying component 130 to drive at least the conveying portion of the second conveying component 130 to rise or fall. The first conveying component 120 is used to convey material to the second conveying component 130 along the second direction Y. The lifting component 140 is used to drive the second conveying component 130 to rise so that the second conveying component 130 can convey material along the first direction X. The second direction Y is perpendicular to the first direction X.

[0053] The lifting assembly 140 is used to drive at least the conveying portion of the second conveying assembly 130 to rise or fall. This means that the lifting assembly 140 can drive the entire second conveying assembly 130 to rise or fall, or it can drive a portion of the second conveying assembly 130 to rise or fall, such as driving the conveying portion to rise or fall. The conveying portion refers to the part of the second conveying assembly 130 used for conveying materials.

[0054] In practical applications, in the initial state, the second conveying component 130 is driven by the lifting component 140 to descend below the support surface of the first conveying component 120, so that the material can be supported on the support surface of the first conveying component 120, and the material is conveyed along the second direction Y by the first conveying component 120; when the first conveying component 120 conveys the material to the second conveying component 130, the material is located above the second conveying component 130, at this time the lifting component 140 drives the second conveying component 130 to rise, so that the second conveying component 130 supports the material, and the material is conveyed along the first direction X by the second conveying component 130, thereby changing the conveying from the second direction Y to the conveying along the first direction X.

[0055] The reversing conveying mechanism 100 in this embodiment of the application, by setting the second conveying component 130 at at least one end of the first conveying component 120 along the second direction Y, and providing a lifting component 140 capable of driving the second conveying component 130 to rise and fall, allows the second conveying component 130 to be lowered to avoid obstructing the material conveying along the second direction Y when the material is conveyed through the first conveying component 120 along the second direction Y. When the material is conveyed to the second conveying component 130, the lifting component 140 drives the second conveying component 130 to rise, so that the second conveying component 130 supports the material and conveys it along the first direction X, thereby changing the conveying direction from the second direction Y to the first direction X. Overall, the reversing conveying mechanism 100 of this application not only realizes the reversing conveying of materials, but also has a simple structure and occupies little space, making its application range wider.

[0056] In some embodiments, please refer to Figure 5 and Figure 6 The reversing conveying mechanism 100 includes a plurality of first conveying components 120 and a plurality of second conveying components 130 arranged at intervals along the second direction Y. Each second conveying component 130 is disposed between two adjacent first conveying components 120 along the second direction Y. The arrangement of multiple second conveying components 130 minimizes the space occupied by a single second conveying component 130, allows each second conveying component 130 to be disposed between two adjacent first conveying components 120 along the second direction Y, and ensures that the material conveying area of ​​each second conveying component 130 and each first conveying component 120 is sufficiently large, facilitating material conveying. It is understood that in other embodiments, a single, larger second conveying component 130 may also be used; this is not a limiting factor.

[0057] In some embodiments, please refer to Figure 6 The reversing conveyor mechanism 100 also includes a material arrival sensor 150, which is used to detect whether the first conveying component 120 conveys material above the second conveying component 130.

[0058] Specifically, the reversing conveyor mechanism 100 also includes a controller, or the upper-level device of the reversing conveyor mechanism 100 includes a controller. The material arrival sensor 150, the lifting assembly 140, the second conveying assembly 130 and the first conveying assembly 120 are all communicatively connected to the controller. The controller first controls the first conveying assembly 120 to convey materials along the second direction Y. When the material is conveyed to the second conveying assembly 130, that is, when the material is conveyed above the second conveying assembly 130, the material arrival sensor 150 detects the material and feeds back to the controller. The controller controls the lifting assembly 140 to raise the second conveying assembly 130 and controls the second conveying assembly 130 to convey materials along the first direction X.

[0059] In some embodiments, please refer to Figure 6 The reversing conveying mechanism 100 includes a first end 180 and a second end 190 arranged opposite each other along the second direction Y. A plurality of first conveying components 120 are sequentially spaced between the first end 180 and the second end 190 and are used to convey materials from the first end 180 to the second end 190. A plurality of second conveying components 130 are interspersed among some of the first conveying components 120. The first distance between each second conveying component 130 and the first end 180 is greater than the second distance between each second conveying component 130 and the second end 190, that is, each second conveying component 130 is arranged close to the second end 190. The material arrival sensor 150 is arranged on the side of each second conveying component 130 away from the first end 180. For ease of description, the position of each second conveying component 130 near the first end 180 is called the starting end, and the position of each second conveying component 130 near the second end 190 is called the ending end. The material arrival sensor 150 is located at the ending end. Then, the first conveying component 120 first conveys the material from the first end 180 to the starting end of each second conveying component 130 and conveys it above each second conveying component 130. At this time, the material arrival sensor 150 detects the material and feeds back to the controller. The controller controls the lifting component 140 to drive the second conveying component 130 to rise to convey the material.

[0060] It should be noted that the aforementioned first distance can be set according to the material conveying requirements. For example, when the first end 180 is connected to the linear conveyor mechanism 200, the material can be directly conveyed to the top of the second conveying component 130 via the linear conveyor mechanism 200. In this case, the first distance can be set very small, for example... Figure 1 The reversing conveyor 100a in the middle can be designed to be smaller. However, when the first end 180 is directly connected to another reversing conveyor 100, the first distance needs to be set larger, for example... Figure 1 The reversing conveyor mechanism 100b in the middle.

[0061] In some embodiments, please refer to Figure 6The second end 190 is provided with a baffle 160, and the material arrival sensor 150 and the baffle 160 are spaced apart along the second direction Y. The baffle 160 can prevent material from falling out of the reversing conveyor mechanism 100 from the second end 190. At the same time, by spaced apart from the baffle 160, there is a reserved space between the material arrival sensor 150 and the baffle 160, which prevents the material from being conveyed between the material arrival sensor 150 and the baffle 160 or falling over the baffle 160 during the time that the material arrival sensor 150 detects the material after it has risen to the position of the second conveying component 130.

[0062] In some embodiments, please refer to Figure 7 and Figure 8 The second conveying assembly 130 is a belt conveyor assembly, which includes a mounting frame 131, a belt drive 132 mounted on the mounting frame 131, two pulleys 133 rotatably mounted on the mounting frame 131, and a belt 134 wound around the two pulleys 133. The lifting assembly 140 is connected to the mounting frame 131. In this embodiment, by mounting the belt drive 132, the two pulleys 133, and the belt 134 on the mounting frame 131, the lifting assembly 140 can drive the mounting frame 131 to rise and fall, thereby driving the second conveying assembly 130 to rise and fall. It is understood that in other embodiments of this application, the belt drive 132 can also be mounted on the frame 110. When the two pulleys 133 and the belt 134 rise and fall, the belt drive 132 remains stationary, thereby reducing the driving power of the lifting assembly 140 and saving energy. Specifically, the belt 134 can be set to be in a slack state at a low position and in a taut state at a high position to convey materials.

[0063] In some embodiments, please refer to Figure 8 The reversing conveyor mechanism 100 includes multiple belt conveyor assemblies spaced apart. Each belt conveyor assembly includes a drive pulley 135. The frame 110 is provided with a connecting shaft 137, and each drive pulley 135 is installed at a different position on the connecting shaft 137. One of the drive pulleys 135 is connected to a belt drive component 132. In this embodiment, the arrangement of the connecting shaft 137 and multiple drive pulleys 135 allows multiple belt conveyor assemblies to be driven simultaneously by a single belt drive component 132 to synchronously convey materials. This not only ensures stable material conveying but also reduces the number of belt drive components 132, thereby reducing their structural cost and space occupation. It is understood that in other embodiments, when space permits, one belt drive component 132 may be provided for each belt conveyor assembly; this is not a unique limitation.

[0064] In some embodiments, please refer to Figure 7The belt conveyor assembly also includes two guide wheels 136, which are respectively mounted on the mounting frame 131 and located on opposite sides of the drive wheel 135. The belt 134 is respectively wound around the drive wheel 135, the two guide wheels 136 and the two pulleys 133.

[0065] Specifically, two guide wheels 136 are located on opposite sides of the drive wheel 135 and above the drive wheel 135. Two pulleys 133 are respectively located on opposite outer sides of the two guide wheels 136 and above the two guide wheels 136. The belt 134 is wound sequentially around the drive wheel 135, one of the guide wheels 136, one of the pulleys 133, the other pulley 133, and the other guide wheel 136 before returning to the drive wheel 135. The arrangement of the two guide wheels 136 facilitates the guidance of the belt 134 from the drive wheel 135 to the two pulleys 133, ensuring not only smooth movement of the belt 134 but also tension, thus guaranteeing the stability of the belt 134's movement and preventing slippage.

[0066] In some embodiments, please refer to Figure 9 The reversing conveying mechanism 100 includes a plurality of spaced-apart second conveying components 130. A lifting component 140 is provided with a lifting frame 145. Mounting brackets 131 of each second conveying component 130 are respectively mounted at different positions on the lifting frame 145. The lifting component 140 is used to drive each second conveying component 130 to move up and down synchronously via the lifting frame 145. In this embodiment, the lifting frame 145 enables the lifting component 140 to simultaneously transport each second conveying component 130 up and down, thereby reducing the number of lifting components 140, their cost, and the space they occupy.

[0067] In some embodiments, please refer to Figure 9 The reversing conveying mechanism 100 includes two sets of lifting components 140, which are respectively disposed at opposite ends of the second conveying component 130. One set of lifting components 140 is used to synchronously drive one end of each second conveying component 130 to rise and fall synchronously, and the other set of lifting components 140 is used to synchronously drive the other end of each second conveying component 130 to rise and fall synchronously. The arrangement of the two sets of lifting components 140 ensures that the opposite ends of the second conveying component 130 can rise and fall smoothly, avoiding the problem of jamming caused by tilting of the second conveying component 130. It is understood that in other embodiments, three or more lifting components 140 may be provided, provided the structural layout allows; this is not a unique limitation.

[0068] Optionally, the two sets of lifting components 140 can be controlled to lift synchronously via a controller.

[0069] Optionally, each of the second conveying components 130 is spaced apart along the second direction Y, and along the first direction X, the belt drive component 132 is located between the two sets of lifting components 140, and the two guide wheels 136 are located between the two sets of lifting components 140. This arrangement allows each of the second conveying components 130 and the two lifting components 140 to be compactly arranged along the second direction Y and the first direction X, occupying little space.

[0070] In some embodiments, please refer to Figure 10 The lifting assembly 140 includes a base 141, a lifting drive 142, a guide rod 143, and a linear bearing 144. The base 141 is mounted on the frame 110; the lifting drive 142 is mounted on the base 141 and connected to the second conveying assembly 130; one end of the guide rod 143 is connected to the second conveying assembly 130; and the linear bearing 144 is mounted on the base 141, with the other end of the guide rod 143 connected to the linear bearing 144. In this embodiment, the cooperation between the guide rod 143 and the linear bearing 144 ensures that the second conveying assembly 130 moves up and down in a straight line, thus ensuring the smoothness of the conveying operation of the second conveying assembly 130.

[0071] In an embodiment where the output of the lifting assembly 140 includes the lifting frame 145, the lifting drive 142 is connected to the lifting frame 145, and the end of the guide rod 143 away from the linear bearing 144 is also connected to the lifting frame 145. The lifting drive 142 drives the lifting frame 145 to lift and lower, thereby driving the second conveying assembly 130 to lift and lower.

[0072] Optionally, the lifting assembly 140 has two guide rods 143 and two linear bearings 144. The lifting drive 142 is located at approximately the center of the base 141 along the second direction Y. The two guide rods 143 are respectively located on opposite sides of the lifting drive 142, and the two linear bearings 144 are respectively corresponding to and guide the two guide rods 143.

[0073] Optionally, the lifting drive 142 includes a linear cylinder, which drives the lifting frame 145 to rise and fall. It is understood that in other embodiments, the lifting drive 142 may also include an electric push rod, a linear motor, a ball screw structure, etc., and is not limited to any particular type.

[0074] In some embodiments, please refer to Figure 10 A buffer 146 is provided on the base 141. The buffer 146 is used to buffer the lifting vibration of the lifting drive and the second conveying component 130, so as to reduce the vibration of the entire reversing conveying mechanism 100 and thus ensure the smooth conveying of materials. The type of buffer 146 can be limited according to actual needs, and is not limited here.

[0075] In some embodiments, please refer to Figure 6 The first conveying assembly 120 is a roller conveying assembly, including an axle 121, multiple rollers 122, and multiple bushings 123. The axle 121 is rotatably mounted on the frame 110. The multiple rollers 122 are respectively sleeved on the axle 121 and are arranged sequentially at intervals along the axial direction of the axle 121. The multiple bushings 123 are respectively sleeved on the axle 121 and abut against the space between two adjacent rollers 122. Each roller conveying assembly also includes a roller drive 124 and a synchronizing element (not shown). The axle 121 of each roller conveying assembly is connected to the roller drive 124 through the synchronizing element. The roller drive 124 drives each axle 121 to rotate synchronously through the synchronizing element. When the roller drive 124 drives each axle 121 to rotate synchronously through the synchronizing element, the axle 121 drives each roller 122 to rotate, thereby conveying materials through each roller 122. In this embodiment, by setting a synchronization component, each first conveying component 120 can share the roller drive component 124, thereby reducing the space occupied and cost of the roller drive component 124.

[0076] Optionally, the synchronizing element can be the same as the synchronizing structure 230 described above. For example, the synchronizing element includes multiple sprockets and chains, with each sprocket mounted on one end of the axle 121, and one sprocket mounted on the roller drive 124. The chain is connected to each sprocket for transmission. It is understood that in other embodiments, the synchronizing element can also be a belt structure, a gear transmission structure, or a rack and pinion structure, etc., and is not limited to these specific embodiments.

[0077] Optionally, the roller drive 124 includes a rotary motor.

[0078] Optionally, in some other embodiments, the first conveying component 120 may be any one of a belt conveyor, chain conveyor, roller conveyor, or pressure roller conveyor, and the second conveying component 130 may be any one of a roller conveyor, chain conveyor, roller conveyor, or pressure roller conveyor, and is not limited thereto.

[0079] Optionally, each of the first conveying components 120 is staggered along the first direction X, so that the rollers 122 in each of the first conveying components 120 are more compactly distributed, and the conveying of materials by each roller 122 is more stable.

[0080] In some embodiments, please refer to Figure 5The corner reversing structure also includes a control box 170, which is mounted on the frame 110. The first conveying component 120, the second conveying component 130, and the lifting component 140 are respectively connected to the control box 170. Users can control the operation of the first conveying component 120, the second conveying component 130, and the lifting component 140, or adjust the parameters of the first conveying component 120, the second conveying component 130, and the lifting component 140 by operating the control box 170.

[0081] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
