[0029] The following specific implementation methods will further illustrate the present application in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0030] In the description of the embodiments of the present application, when an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be a centrally arranged element at the same time. When an element is considered to be "set on" another element, it may be directly set on the other element or there may be a centrally arranged element at the same time. In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a communication between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. The directional descriptions in this embodiment, such as "up", "down", "top", "bottom", etc., are all referenced to the direction of the product in the actual usage scenario.

[0031] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] Currently, in the processing of semiconductor or photovoltaic materials, multiple production lines are usually required to move materials to different workstations for processing to complete the loading and unloading operations. However, these multiple production lines usually operate independently of each other.

[0033] Taking the ALD (atomic layer deposition) process as an example, during the automatic loading and unloading process, the material is placed on a carrier. A fully loaded carrier is loaded via a loading line, which transports the carrier and the material to the corresponding processing equipment, which removes the material from the carrier. An empty carrier is unloaded via a discharging line, which transports the carrier to a designated location for recycling. As a result, the loading and unloading lines are set up independently and do not interfere with each other, resulting in a very long assembly line, a large equipment footprint, and reduced work efficiency.

[0034] To this end, an embodiment of the present application provides a return transport device that can achieve the technical effect of shortening the length of the assembly line and improving work efficiency.

[0035] Figure 1 This is a schematic structural diagram of the reflux transport device provided in this application. Figure 2 This is a schematic diagram of the status of the return transport device provided in this application when transporting a carrier.

[0036] like Figure 1 and Figure 2 As shown, the return transport device 100 includes a conveying mechanism 10 and a return mechanism 20. The number of conveying mechanisms 10 is greater than or equal to two, and the multiple conveying mechanisms 10 are spaced apart in a first direction (i.e., the Y-axis direction in the figure). The conveying mechanism 10 is used to transport the carrier 200 to complete the corresponding conveying action. The return mechanism 20 is used to interface with the multiple conveying mechanisms 10 and transport materials between the multiple conveying mechanisms 10.

[0037] In this embodiment, the carrier 200 has a fully loaded state and an empty state, and the conveying mechanism 10 and the reflux mechanism 20 can both convey the carrier 200 in both states. When the carrier 200 is loaded with materials, the carrier 200 is in a fully loaded state; when the carrier 200 is not loaded with materials, the carrier 200 is in an empty state. It can be understood that the types of carriers 200 and materials can be configured according to the actual application scenario. For example, the reflux transport device 100 provided in this embodiment can be applied to the ALD process, the carrier 200 can be a carrier, and the materials can be sheet materials such as silicon wafers, silicon carbide wafers, etc. used as solar cell wafers.

[0038] In this embodiment, the two conveying mechanisms 10 are respectively the first conveying mechanism 10a and the second conveying mechanism 10b. The first conveying mechanism 10a and the second conveying mechanism 10b are respectively used to complete different conveying actions. The reflux mechanism 20 can convey materials between the first conveying mechanism 10a and the second conveying mechanism 10b.

[0039] Exemplarily, the conveying action includes a loading action and an unloading action. The conveying mechanism 10 that performs the loading action can serve as the first conveying mechanism 10a, and the conveying mechanism 10 that performs the unloading action can serve as the second conveying mechanism 10b.

[0040] The first conveyor mechanism 10a is positioned corresponding to the loading station 101, which serves as the starting point for the movement of the carrier 200 during loading and unloading. During loading, the first conveyor mechanism 10a receives a fully loaded carrier 200 (hereinafter referred to as a fully loaded carrier 200) from the loading station 101 and transports the carrier 200 to a designated location for removal by other equipment for processing.

[0041] The second conveyor mechanism 10b is positioned corresponding to the unloading station 104, which serves as the final destination for the carrier 200 during loading and unloading. During unloading, the second conveyor mechanism 10b receives an empty carrier 200 (hereinafter referred to as an empty carrier 200) from a designated location and transports the carrier 200 to the unloading station 104 for retrieval or reloading.

[0042] In this embodiment, the reflow mechanism 20 includes a frame 30, a drive assembly 50, and a transfer assembly 40. The drive assembly 50 is disposed on the frame 30, and the transfer assembly 40 is connected to the drive assembly 50. The transfer assembly 40 is driven by the drive assembly 50 to move in a first direction and pass through the first reflow station 102 and the second reflow station 103.

[0043] One end of the first conveying mechanism 10a is disposed corresponding to the first reflow station 102. When the transfer assembly 40 moves to the first reflow station 102, the transfer assembly 40 docks with the first conveying mechanism 10a, allowing the first conveying mechanism 10a to convey the carrier 200 to the transfer assembly 40.

[0044] One end of the second conveying mechanism 10b is disposed corresponding to the second reflow station 103. When the transfer assembly 40 moves to the second reflow station 103, the transfer assembly 40 docks with the second conveying mechanism 10b, so that the transfer assembly 40 can convey the carrier 200 to the second conveying mechanism 10b.

[0045] During automatic loading and unloading, the drive assembly 50 first drives the transfer assembly 40 to the first reflow station 102, docking the transfer assembly 40 with the first conveyor mechanism 10a. The first conveyor mechanism 10a then transports the fully loaded carrier 200 from the loading station 101 to the first reflow station 102, where it is then transported to the transfer assembly 40. Other equipment can then remove the material from the carrier 200. The drive assembly 50 then drives the transfer assembly 40 to the second reflow station 103, docking the transfer assembly 40 with the second conveyor mechanism 10b. The transfer assembly 40 then transports the empty carrier 200 from the second reflow station 103 to the second conveyor mechanism 10b. The second conveyor mechanism 10b then transports the empty carrier 200 to the unloading station 104.

[0046] In this way, the first conveyor mechanism 10a forms the loading line, the second conveyor mechanism 10b forms the unloading line, and the return mechanism 20 can be installed as a return line between the loading and unloading lines, establishing a connection between the loading and unloading lines. When the carrier 200 passes through the first conveyor mechanism 10a, the return mechanism 20, and the second conveyor mechanism 10b in sequence, the loading and unloading process is completed automatically. This optimizes the conveying route of the carrier 200 and shortens the length of the entire assembly line, thereby reducing the equipment footprint and improving work efficiency.

[0047] Figure 3 This is a schematic structural diagram of the first conveying mechanism provided in this application.

[0048] like Figure 2 and Figure 3As shown, in one embodiment of the present application, the conveying mechanism 10 includes a conveying bracket 11, a conveying drive member 12, a conveying drive wheel 13 and a conveying timing belt 14. The conveying drive member 12 is arranged on the conveying bracket 11, the conveying drive wheel 13 is rotatably connected to the conveying bracket 11, and the conveying drive wheel 13 is connected to the conveying drive member 12. The conveying timing belt 14 is transmission-connected to the conveying drive wheel 13, and the conveying timing belt 14 extends along a second direction, and the second direction has an angle with the first direction. The second direction includes the X1 axis direction and the X2 axis direction shown in the figure, the X1 axis direction is the positive direction of the X axis direction, and the X2 axis direction is the reverse direction of the X axis direction.

[0049] In practical applications, the upper surface of the conveyor timing belt 14 can carry the carrier 200. When the conveyor driving member 12 drives the conveyor driving wheel 13 to rotate, the conveyor driving wheel 13 drives the conveyor timing belt 14 to work, so that the conveyor timing belt 14 conveys the carried carrier 200 in the second direction.

[0050] The two ends of the conveyor belt 14 form an inlet end and an outlet end, and the conveyor belt 14 can transport the carrier 200 from the inlet end to the outlet end. It is understood that the inlet end and the outlet end of the conveyor belt 14 can be interchanged according to the conveying direction of the conveyor belt 14, and the position, length, conveying direction, etc. of the conveyor belt 14 can be configured according to the requirements of the specific application scenario, such as the requirements of the work station design and the requirements of the loading and unloading operation.

[0051] The conveying mechanism 10 of the present application conveys the carrier 200 via the conveying synchronous belt 14. In practical applications, the carrier 200 can be cyclically conveyed in a specified direction, thereby improving conveying efficiency. In other embodiments, considering the conveying requirements of the carrier 200, such as when the carrier 200 needs to be moved back and forth or in multiple directions, a mechanism such as a screw slide, a gear rack, or a combination of multiple synchronous belt mechanisms can be used, and this application is not limited to this.

[0052] Exemplarily, the conveying bracket 11 includes a first frame 111, a second frame 112 and a connecting rod 113. The first frame 111 and the second frame 112 are spaced apart in the first direction, and the first frame 111 and the second frame 112 are both extended along the second direction. The connecting rod 113 is located between the first frame 111 and the second frame 112. One end of the connecting rod 113 is bolted and fixed to the first frame 111, and the other end of the connecting rod 113 is bolted and fixed to the second frame 112. The connecting rod 113 can strengthen the connection strength between the first frame 111 and the second frame 112. There are multiple connecting rods 113, and the multiple connecting rods 113 are spaced apart along the second direction. The top surface height of the connecting rod 113 is less than the upper surface height of the conveying synchronous belt 14 to prevent the connecting rod 113 from interfering with the conveying of the carrier 200.

[0053] Exemplarily, there are multiple conveyor timing belts 14, which are spaced apart in the first direction. Multiple conveyor timing belts 14 can simultaneously support the carrier 200, thereby improving the smoothness of the conveying of the carrier 200 and preventing the carrier 200 from deviating from its position during transportation. Furthermore, a certain amount of space can be left between the multiple conveyor timing belts 14 for other structural arrangements, thereby improving space utilization. In this embodiment, the number of conveyor timing belts 14 is two, and the distance between the two conveyor timing belts 14 corresponds to the width of the carrier 200 in the first direction. The first frame 111 and the second frame 112 are respectively arranged to correspond to the two conveyor timing belts 14.

[0054] Exemplarily, there are also multiple conveying drive wheels 13, and the position and number of the conveying drive wheels 13 correspond to the position and number of the conveying synchronous belt 14. The conveying drive wheels 13 are located at the ends of the conveying synchronous belt 14, and the conveying synchronous belt 14 is sleeved on the conveying drive wheels 13. In the example of this embodiment, each conveying synchronous belt 14 is provided with a conveying drive wheel 13 at both ends, and the number of conveying drive wheels 13 is four. The two conveying drive wheels 13 corresponding to one of the conveying synchronous belts 14 are respectively rotatably connected to the two ends of the first frame 111, and the two conveying drive wheels 13 corresponding to the other conveying synchronous belt 14 are respectively rotatably connected to the two ends of the second frame 112.

[0055] Illustratively, the conveyor drive member 12 is bolted to one end of the first frame 111. The conveyor drive member 12 may be a servo motor, and the output shaft of the conveyor drive member 12 is coaxially connected to the conveyor drive wheel 13. In this embodiment, the second direction has a forward direction and a reverse direction. By driving the conveyor drive wheel 13 in a clockwise or counterclockwise direction by the conveyor drive member 12, the carrier 200 can be conveyed in the forward or reverse direction of the second direction.

[0056] Figure 4 This is a schematic structural diagram of the conveying drive wheel and conveying synchronous belt provided in this application.

[0057] like Figure 3 and Figure 4 As shown, in one embodiment of the present application, a transmission tooth groove is provided on the circumference of the conveying drive wheel 13, and a transmission tooth tooth adapted to the transmission tooth groove is provided on the inner side of the conveying timing belt 14. When the conveying drive wheel 13 rotates, the conveying timing belt 14 contacts the conveying drive wheel 13, and the transmission tooth groove and the transmission tooth tooth mesh with each other to achieve transmission, thereby improving the conveying efficiency of the conveying timing belt 14 and reducing the risk of the conveying timing belt 14 slipping.

[0058] In one embodiment of the present application, positioning ribs 131 are provided on the circumference of the conveying drive wheel 13, and positioning grooves 141 are provided on the inner side of the conveying timing belt 14 to match the positioning ribs 131. The positioning ribs 131 and the positioning grooves 141 are positioned and matched in the first direction. For example, the positioning ribs 131 protrude from the surface of the transmission tooth grooves, and are distributed in an annular shape along the circumference of the conveying drive wheel 13, with the annular axis of the positioning ribs 131 being arranged parallel to the first direction.

[0059] When the conveying drive wheel 13 rotates, the conveying timing belt 14 contacts the conveying drive wheel 13, and the positioning rib 131 is embedded in the positioning groove 141, preventing the conveying timing belt 14 from deviating from the conveying drive wheel 13 in the first direction, thereby reducing the risk of the conveying timing belt 14 detaching from the conveying drive wheel 13.

[0060] Figure 5 A schematic structural diagram of the bottom of the carrier provided in this application. Figure 6 This is a schematic diagram of the state when the carrier provided in this application is placed on the conveyor timing belt at a suitable angle.

[0061] like Figure 5 As shown, in one embodiment of the present application, a clearance groove 201 is provided at the bottom of the carrier 200, and the clearance groove 201 passes through two opposite sides of the carrier 200. Exemplarily, the carrier 200 has a first side 202 and a second side 203 that are oppositely disposed, and the clearance groove 201 passes through the first side 202 and the second side 203 in a straight line.

[0062] Figure 6 This is a schematic diagram of the state when the carrier provided in this application is placed on the conveyor timing belt at a suitable angle.

[0063] like Figure 3 and Figure 6 As shown, the conveying mechanism 10 further includes a stopper 15, which is adapted to fit within the clearance groove 201. The stopper 15 is connected to the conveying support 11 and is positioned along the moving path of the carrier 200. The moving path of the carrier 200 is driven by the conveying timing belt 14.

[0064] When the carrier 200 is placed on the conveyor timing belt 14 and the clearance groove 201 is parallel to the second direction, the stopper 15 can move relative to the clearance groove 201, allowing the stopper 15 to pass through the clearance groove 201 along the second direction. In this way, when the conveyor timing belt 14 drives the carrier 200 to move past the stopper 15, the stopper 15 passes through the bottom of the carrier 200 through the clearance groove 201, preventing interference between the stopper 15 and the carrier 200 and allowing the carrier 200 to continue moving.

[0065] Conversely, when the carrier 200 is placed on the conveyor timing belt 14 and the clearance groove 201 deviates from the second direction, the stopper 15 cannot move relative to the clearance groove 201, so that the stopper 15 cannot pass through the clearance groove 201 in the second direction. In this case, when the conveyor timing belt 14 drives the carrier 200 to move past the stopper 15, the stopper 15 abuts against the side wall of the carrier 200, causing positional interference with the carrier 200 and preventing the carrier 200 from moving further.

[0066] In this way, the block 15 has the function of limiting the angle of the give way groove 201, thereby playing a fool-proof role in the placement angle of the carrier 200 on the synchronous belt assembly, allowing only the carrier 200 placed at a suitable angle to pass through, preventing the carrier 200 from being placed at an inappropriate angle and causing abnormal execution of subsequent processes.

[0067] like Figure 1 、 Figure 5 and Figure 6 As shown, further, the clearance groove 201 is eccentrically arranged relative to the geometric center of the conveying carrier 200.

[0068] Specifically, the stopper 15 has an eccentric distance from the geometric center of the conveying bracket 11 in the first direction, so that the clearance groove 201 deviates from the geometric center of the conveying carrier 200. The dotted line A in the figure is a straight line passing through the geometric center of the conveying bracket 11.

[0069] When the carrier 200 is placed on the conveyor timing belt 14, the clearance groove 201 is arranged parallel to the second direction, and the first side 202 of the carrier 200 faces the reflow mechanism 20, the stopper 15 can move relatively in the clearance groove 201, allowing the stopper 15 to move through the clearance groove 201. At this time, when the conveyor timing belt 14 drives the carrier 200 to move past the stopper 15, the stopper 15 passes through the bottom of the carrier 200 through the clearance groove 201, preventing interference between the stopper 15 and the carrier 200, allowing the carrier 200 to continue moving.

[0070] Conversely, when the carrier 200 is placed on the conveyor timing belt 14 and the clearance groove 201 is offset from the second direction, or when the carrier 200 is placed on the conveyor timing belt 14 and the clearance groove 201 is parallel to the second direction, and the second side 203 of the carrier 200 is facing the recirculation mechanism 20, the stopper 15 cannot move relative to the clearance groove 201. In this case, when the conveyor timing belt 14 drives the carrier 200 to move past the stopper 15, the stopper 15 abuts against the side wall of the carrier 200, causing positional interference with the carrier 200 and preventing the carrier 200 from moving further.

[0071] In this way, the stopper 15 plays a foolproof role in the placement direction of the carrier 200, allowing only the carrier 200 placed in the appropriate direction to pass through, preventing the carrier 200 from being placed in an inappropriate direction and causing abnormal execution of subsequent processes.

[0072] For example, the upper portion of carrier 200 is used to load materials placed at a specific angle. The bottom of carrier 200 is generally rectangular, with the width of carrier 200 defining a first side 202 and a second side 203. The first side 202 and second side 203 can be configured based on process requirements, such as the direction in which materials are loaded, the actual direction in which carrier 200 moves, and the direction in which materials are grabbed by other equipment in subsequent processes.

[0073] like Figure 3 and Figure 6 As shown, the stopper 15 is located between two adjacent conveyor timing belts 14, and the upper end of the stopper 15 is higher than the upper surface of the conveyor timing belts 14. A connecting block 114 is provided on one side of the connecting rod 113. There is a distance between the connecting block 114 and the middle of the connecting rod 113. The connecting block 114 is bolted to the connecting rod 113, and the stopper 15 is mounted and fixed to the connecting block 114.

[0074] When the carrier 200 is placed on the conveyor belt 14 , the upper end of the stopper 15 protrudes from the upper surface of the conveyor belt 14 to pass through the moving path of the carrier 200 driven by the conveyor belt 14 .

[0075] Figure 7 This is a schematic structural diagram of the second conveying mechanism provided in this application.

[0076] like Figure 2 and Figure 7 As shown, in one embodiment of the present application, the conveying mechanism 10 further includes a check member 16, which is connected to the conveying bracket 11. The check member 16 is located on a side of the conveying bracket 11 away from the second reflow station 103, and the position of the check member 16 is located on the moving path of the carrier 200.

[0077] When the carrier 200 moves past the stopper 16 in a direction away from the middle of the delivery rack 11 , the stopper 16 abuts against the side of the carrier 200 to prevent the carrier 200 from moving further.

[0078] It is understood that during the process of conveying the carrier 200 by the conveyor timing belt 14, the carrier 200 first moves from the inlet end of the conveyor timing belt 14 to the middle of the conveyor support 11, and then moves from the middle of the conveyor support 11 to the outlet end of the conveyor timing belt 14. In this way, the check member 16 has a travel positioning function for the conveyed carrier 200, which can stop and position the moving carrier 200 at a specified position to facilitate subsequent operations on the carrier 200.

[0079] Figure 8 This is a schematic structural diagram of the non-return member, rotating seat and positioning member provided in this application.

[0080] like Figure 2 、 Figure 7 and Figure 8 As shown, in this embodiment, the conveying bracket 11 is provided with a rotating base 17, and the check member 16 is rotatably connected to the rotating base 17 via a rotating shaft 164. One end of the check member 16 is provided with a force-bearing end 161 for contacting the carrier 200, and the check member 16 has a blocking state and an avoidance state that are switched by rotation.

[0081] When the check member 16 rotates to the blocking state, the force-bearing end 161 is located on the moving path of the carrier 200 ; when the check member 16 rotates to the avoiding state, the force-bearing end 161 is away from the moving path of the carrier 200 .

[0082] It can be understood that when the check member 16 is needed to stop the carrier 200, the check member 16 can be placed in a blocking state, and when the check member 16 is not needed to stop the carrier 200, the check member 16 can be placed in an avoidance state. In this way, the function of the check member 16 can be adjusted to suit a variety of different application scenarios.

[0083] For example, while the carrier 200 is moving from the entrance of the conveyor belt 14 to the middle of the conveyor support 11, the check member 16 can switch to a circumventing state, allowing the carrier 200 to continue moving. While the carrier 200 is moving from the middle of the conveyor support 11 to the exit of the conveyor belt 14, the check member 16 can remain in a blocking state, preventing the carrier 200 from further moving. This allows the check member 16 to only stop carriers 200 that have already been transported by the conveyor belt 14, preventing the check member 16 from stopping carriers 200 that have just entered the conveyor belt 14.

[0084] In this embodiment, the rotating seat 17 is provided with a positioning member 18 . The positioning member 18 is located on one side of the rotating shaft 164 close to the middle of the conveying bracket 11 .

[0085] If the carrier 200 moves toward the middle of the delivery bracket 11 and abuts against the force-bearing end 161 , the carrier 200 moves along the X1 axis in the figure, and the anti-return member 16 can rotate around the rotation axis 164 to an evasive state.

[0086] If the carrier 200 moves away from the middle of the delivery bracket 11 and abuts the force-bearing end 161 , the carrier 200 moves along the X2 axis in the figure, and the positioning member 18 abuts the anti-return member 16 to maintain the anti-return member 16 in a blocking state.

[0087] It can be understood that in the process of the carrier 200 moving from the entrance end of the conveyor belt 14 to the middle of the conveyor bracket 11, when the carrier 200 abuts against the check member 16, the check member 16 can automatically rotate to an avoidance state following the movement of the carrier 200, allowing the carrier 200 to continue moving.

[0088] When the carrier 200 moves from the middle of the conveying support 11 to the exit end of the conveying synchronous belt 14 , the positioning member 18 prevents the check member 16 from following the movement of the carrier 200 , thereby preventing the carrier 200 from continuing to move.

[0089] It can be understood that by utilizing the automatic state switching function of the check member 16, a check member 16 can be set at both ends of the conveying bracket 11. The check member 16 will automatically switch to an avoidance state or a blocking state according to the moving direction of the carrier 200, thereby reducing the restrictions on the conveying direction and installation orientation of the conveyor timing belt 14.

[0090] Exemplarily, the check member 16 is located between two adjacent conveyor timing belts 14. The rotating shaft 164 of the check member 16 is arranged parallel to the horizontal direction. The end of the check member 16 away from the force-bearing end 161 is provided with a counterweight end 162. The counterweight end 162 is used to set the force-bearing end 161 upward under the action of gravity. When the check member 16 is in the blocking state, the height of the force-bearing end 161 is higher than the height of the upper surface of the conveyor timing belt 14.

[0091] When the carrier 200 is placed on the conveyor belt 14 and the check member 16 is in the blocking state, the force-bearing end 161 of the check member 16 protrudes from the upper surface of the conveyor belt 14 to pass through the moving path of the carrier 200 driven by the conveyor belt 14 .

[0092] The rotating seat 17 is bolted and fixed to one side of the connecting rod 113 away from the middle of the conveying bracket 11. The rotating seat 17 is provided with a rotating groove 171. The rotating groove 171 passes through the middle of the rotating seat 17 away from the conveying bracket 11, and the rotating groove 171 passes through the upper and lower sides of the rotating seat 17.

[0093] The backstop 16 is mounted in a rotation groove 171. The rotation shaft 164 passes through the middle of the backstop 16 and is connected to the rotation base 17. The positioning member 18 is mounted in the rotation groove 171, and the height of the positioning member 18 is lower than that of the rotation shaft 164. The force-bearing end 161 of the backstop 16 is provided with a relief surface 163, which is inclined downwardly away from the middle of the conveyor bracket 11.

[0094] When the check member 16 is not in contact with the carrier 200, the counterweight end 162 is downwardly disposed and the force-bearing end 161 is upwardly disposed. There is a gap between the positioning member 18 and the check member 16, and the check member 16 is in a blocking state.

[0095] When the carrier 200 moves to the position of the check member 16 in a direction away from the middle of the conveying bracket 11 and abuts against the check member 16, the check member 16 first flips slightly, and then the positioning member 18 abuts against the counterweight end 162 to prevent the check member 16 from rotating from the blocking state to the avoidance state.

[0096] When the carrier 200 moves to the position of the check member 16 in a direction close to the middle of the conveying bracket 11 and abuts against the check member 16, the carrier 200 abuts against the yield surface 163 and drives the check member 16 to flip over. Before the positioning member 18 abuts against the check member 16, the force-bearing end 161 can be accommodated in the rotating groove 171 to move away from the moving path of the carrier 200. At this time, the check member 16 rotates to an avoidance state.

[0097] It can be understood that by setting the inclination angle of the yield surface 163 , the rotation angle required for the check member 16 to rotate to the yield state can be reduced, thereby reducing the space required for the check member 16 .

[0098] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, the conveying mechanism 10 can be divided into a first conveying mechanism 10a and a second conveying mechanism 10b, and correspondingly, the second direction includes opposite loading direction and unloading direction, wherein the loading direction is the X1 axis direction in the figure, and the unloading direction is the X2 axis direction in the figure.

[0099] The conveying synchronous belt 14 of the first conveying mechanism 10 a is used to convey the carrier 200 in the loading direction, and allows the carrier 200 to pass through the loading station 101 and the first reflow station 102 in sequence.

[0100] The conveying synchronous belt 14 of the second conveying mechanism 10b is used to convey the carrier 200 in the unloading direction, and allows the carrier 200 to pass through the second reflow station 103 and the unloading station 104 in sequence. The loading station 101 and the unloading station 104 are spaced apart in the first direction.

[0101] In this way, the distance between the first conveying mechanism 10a and the second conveying mechanism 10b can be shortened, and the distance between the loading station 101 and the unloading station 104 can be shortened, thereby increasing the floor space of the entire equipment; on the other hand, the loading station 101 and the unloading station 104 can be located in a similar area to facilitate the input and recovery of the carrier 200 at a similar location, thereby simplifying the design layout of the entire machine station.

[0102] like Figure 2 、 Figure 3 and Figure 7 As shown, for example, the conveying support 11 can be divided into a first conveying support 11a and a second conveying support 11b. The conveying drive member 12 can be divided into a first conveying drive member 12a and a second conveying drive member 12b. The conveying drive wheel 13 can be divided into a first conveying drive wheel 13a and a second conveying drive wheel 13b. The conveying timing belt 14 can be divided into a first conveying timing belt 14a and a second conveying timing belt 14b.

[0103] The first conveying mechanism 10a includes a first conveying bracket 11a, a first conveying drive member 12a, a first conveying drive wheel 13a, and a first conveying timing belt 14a. The inlet end of the first conveying timing belt 14a is arranged corresponding to the loading station 101, and the outlet end of the first conveying timing belt 14a is arranged corresponding to the first reflow station 102. This allows the first conveying timing belt 14a to receive a fully loaded carrier 200 at the loading station 101 and transport the carrier 200 from the loading station 101 to the first reflow station 102.

[0104] The second conveying mechanism 10b includes a second conveying bracket 11b, a second conveying drive member 12b, a second conveying drive wheel 13b, and a second conveying timing belt 14b. The first conveying timing belt 14a and the second conveying timing belt 14b are spaced apart and arranged parallel to each other in a first direction. The inlet end of the second conveying timing belt 14a corresponds to the second reflow station 103, and the outlet end of the second conveying timing belt 14b corresponds to the unloading station 104. This allows the second conveying timing belt 14b to receive an unloaded carrier 200 at the second reflow station 103 and transport the carrier 200 from the second reflow station 103 to the unloading station 104.

[0105] In the example of this embodiment, the first conveying mechanism 10 a includes a stopper 15 . The stopper 15 is connected to the first conveying bracket 11 a , and the stopper 15 is located at the inlet end of the first conveying synchronous belt 14 a .

[0106] Thus, after the fully loaded carrier 200 is put into the first conveyor belt 14a, it can quickly pass the position of the block 15, so that the block 15 can quickly filter out the carrier 200 with the wrong angle or direction, thereby reducing the resulting production loss.

[0107] In this embodiment, the second conveying mechanism 10b includes a check member 16 connected to the second conveying bracket 11b. There are multiple check members 16, which are respectively located at both ends of the second conveying bracket 11b.

[0108] In this way, when the carrier 200 enters the entrance end of the second conveyor timing belt 14b and passes through the corresponding check piece 16, the check piece 16 will automatically switch to the avoidance state to allow the carrier 200 to pass; when the carrier 200 arrives at the exit end of the second conveyor timing belt 14b and passes through the corresponding check piece 16, the check piece 16 will remain in the blocking state to stop the carrier 200.

[0109] It is worth noting that the specific configurations of the first conveying mechanism 10a and the second conveying mechanism 10b can be adaptively set according to actual needs; for example, in other embodiments, the conveying speeds of the first conveying synchronous belt 14a and the second conveying synchronous belt 14b can be set specifically, the lengths of the first conveying synchronous belt 14a and the second conveying synchronous belt 14b can be adaptively adjusted, the first conveying bracket 11a or the second conveying bracket 11b can be installed with a block 15 and a check member 16 at the same time, etc., and this application does not impose any restrictions on this.

[0110] Figure 9 A schematic diagram of the structure of the transfer component provided for this application.

[0111] like Figure 2 and Figure 9 As shown, in one embodiment of the present application, the transfer assembly 40 includes a return bracket 41, a return drive member 42, a return drive wheel 43, and a return timing belt 44. The return drive member 42 is disposed on the return bracket 41, the return drive wheel 43 is rotatably connected to the return bracket 41, and the return drive wheel 43 is connected to the return drive member 42. The return timing belt 44 is in transmission connection with the return drive wheel 43 and extends along the second direction.

[0112] In practical applications, the upper surface of the return synchronous belt 44 can carry the carrier 200. When the return driving member 42 drives the return driving wheel 43 to rotate, the return driving wheel 43 drives the return synchronous belt 44 to work, so that the return synchronous belt 44 transports the carried carrier 200 in the second direction.

[0113] like Figure 1 、 Figure 2 and Figure 9 As shown, the return timing belt 44 is provided corresponding to the conveyor timing belt 14. When the return timing belt 44 moves to a position aligned with the conveyor timing belt 14 in the first direction, the return timing belt 44 docks with the conveyor timing belt 14. At this time, a continuous timing belt can be formed between the return timing belt 44 and the docked conveyor timing belt 14 to realize the conveyance of the carrier 200, so that the return timing belt 44 can transport the carrier 200 to the conveyor timing belt 14, and vice versa.

[0114] In this embodiment, when the reflow timing belt 44 moves to the first reflow station 102, the reflow timing belt 44 docks with the conveyor timing belt 14 of the first conveyor mechanism 10a. When the reflow timing belt 44 moves to the second reflow station 103, the reflow timing belt 44 docks with the conveyor timing belt 14 of the second conveyor mechanism 10b.

[0115] The transfer component 40 of the present application transports the carrier 200 through the reflux synchronous belt 44. In other embodiments, considering the transportation requirements of the carrier 200, for example, when the carrier 200 needs to be moved back and forth or in multiple directions, a screw slide, a gear rack and other mechanisms can be used, or a combination of multiple synchronous belt mechanisms can be used. This application does not limit this.

[0116] Exemplarily, the reflux bracket 41 includes a first fixing bracket 411, a second fixing bracket 412, and a base bracket 413. The base bracket 413 is connected to the drive assembly 50, and the first fixing bracket 411 and the second fixing bracket 412 are bolted to the upper side of the base bracket 413. The first fixing bracket 411 and the second fixing bracket 412 are spaced apart in the first direction and both extend along the second direction.

[0117] There are multiple return timing belts 44, spaced apart in the first direction. These multiple return timing belts 44 can simultaneously support the carrier 200, improving the smoothness of the carrier 200's transportation and preventing the carrier 200 from shifting during transportation. Furthermore, space can be left between the multiple return timing belts 44 for other structural arrangements, improving space utilization. In this embodiment, there are two return timing belts 44, and the distance and height between the two return timing belts 44 correspond to the spacing and height of the conveyor timing belts 14. The first mounting bracket 411 and the second mounting bracket 412 are respectively arranged to correspond to the two return timing belts 44.

[0118] There are also multiple reflux drive wheels 43. The position and number of the reflux drive wheels 43 correspond to the position and number of the reflux synchronous belts 44. The reflux drive wheels 43 are located at the ends of the reflux synchronous belts 44, and the reflux synchronous belts 44 are sleeved around the reflux drive wheels 43. In this embodiment, a reflux drive wheel 43 is provided at both ends of each reflux synchronous belt 44. The number of reflux drive wheels 43 is four. The two reflux drive wheels 43 corresponding to one reflux synchronous belt 44 are respectively rotatably connected to the two ends of the first fixing frame 411, and the two reflux drive wheels 43 corresponding to the other reflux synchronous belt 44 are respectively rotatably connected to the two ends of the second fixing frame 412.

[0119] Exemplarily, the reflux drive member 42 is bolted to one end of the first fixed frame 411. The reflux drive member 42 can be a servo motor, and the output shaft of the reflux drive member 42 is coaxially connected to the reflux drive wheel 43. In the example of this embodiment, the second direction has a forward direction and a reverse direction. The reflux drive member 42 drives the reflux drive wheel 43 to rotate in a clockwise direction or a counterclockwise direction, so as to realize the conveyance of the carrier 200 in the forward or reverse direction of the second direction. When the carrier 200 moves in the forward direction of the second direction, the carrier 200 can be conveyed from the reflux timing belt 44 to the conveying timing belt 14; when the carrier 200 moves in the reverse direction of the first direction, the carrier 200 can be conveyed from the conveying timing belt 14 to the reflux timing belt 44.

[0120] Figure 10 This is a schematic structural diagram of the reflux drive wheel and reflux synchronous belt provided in this application.

[0121] like Figure 9 and Figure 10 As shown, in one embodiment of the present application, meshing grooves are provided on the circumference of the return drive wheel 43, and meshing teeth that match the meshing grooves are provided on the inner side of the return timing belt 44. When the return drive wheel 43 rotates, the return timing belt 44 contacts the return drive wheel 43, and the meshing grooves and meshing teeth achieve meshing transmission, thereby improving the return efficiency of the return timing belt 44 and reducing the risk of the return timing belt 44 slipping.

[0122] In one embodiment of the present application, a limiting rib 431 is provided on the circumference of the return drive wheel 43, and a limiting groove 441 is provided on the inner side of the return timing belt 44 to match the limiting rib 431. The limiting rib 431 and the limiting groove 441 are positioned and matched in the first direction. For example, the limiting rib 431 protrudes from the surface of the meshing tooth groove, and the limiting rib 431 is annularly distributed along the circumference of the return drive wheel 43, and the annular axis of the limiting rib 431 is arranged parallel to the first direction.

[0123] When the reflux driving wheel 43 rotates, the reflux synchronous belt 44 contacts the reflux driving wheel 43, and the limiting rib 431 is embedded in the limiting groove 441, preventing the reflux synchronous belt 44 from deviating from the reflux driving wheel 43 in the first direction, thereby reducing the risk of the reflux synchronous belt 44 detaching from the reflux driving wheel 43.

[0124] like Figure 1 、 Figure 2 and Figure 9 As shown, in one embodiment of the present application, the transfer assembly 40 further includes a blocking member 45, which is connected to the return bracket 41 and is located at an end of the return synchronous belt 44 away from the conveying mechanism 10. For example, the number of blocking members 45 is two, and the two blocking members 45 are bolted to the first fixing bracket 411 and the second fixing bracket 412, respectively.

[0125] When the carrier 200 moves past the blocking member 45 in a direction away from the conveyor timing belt 14, the blocking member 45 abuts against the side of the carrier 200, preventing the carrier 200 from moving further. At this point, the carrier 200 is supported by the return timing belt 44, and there is no contact between the carrier 200 and the conveyor timing belt 14. Driven by the drive assembly 50, the return timing belt 44 can independently drive the carrier 200 in the first direction, preventing the conveyor timing belt 14 from interfering with the movement of the carrier 200 in the first direction.

[0126] On the other hand, the blocking member 45 has a travel positioning function for the carrier 200 , and can stop and position the moving carrier 200 at a specified position, thereby preventing the carrier 200 from excessively moving under the drive of the return synchronous belt 44 .

[0127] In one embodiment of the present application, a bottom portion of the carrier 200 is provided with positioning holes 204. A plurality of positioning holes 204 are provided, and the plurality of positioning holes 204 are spaced apart. For example, the number of positioning holes 204 is two, and the two positioning holes 204 are distributed along the diagonal direction of the carrier 200.

[0128] Figure 11 This is a schematic diagram of the structure of the reflux mechanism provided in this application.

[0129] like Figure 5 and Figure 11 As shown, the transfer assembly 40 further includes a lifting platform 46 and a lifting drive 47, wherein the lifting drive 47 is disposed on the reflux bracket 41, the lifting platform 46 is connected to the lifting drive 47, and a top of the lifting platform 46 is provided with positioning posts 461 adapted to the positioning holes 204. The number and distribution of the positioning posts 461 correspond to the number and distribution of the positioning holes 204. When the carrier 200 moves to a position abutting against the blocking member 45, the positioning posts 461 can be aligned with the positioning holes 204 in the third direction (i.e., the Z-axis direction shown in the figure).

[0130] The lifting drive 47 is used to drive the lifting platform 46 to move in the third direction through a first position and a second position. The first direction and the second direction both form an angle with the third direction. When the carrier 200 is supported by the reflow timing belt 44 and the lifting platform 46 moves to the first position, the positioning post 461 engages with the positioning hole 204 of the carrier 200. When the carrier 200 is supported by the reflow timing belt 44 and the lifting platform 46 moves to the second position, the positioning post 461 disengages from the positioning hole 204 of the carrier 200.

[0131] like Figure 1 、 Figure 5 and Figure 11As shown, when the return timing belt 44 needs to be docked with the conveyor timing belt 14 to transport the carrier 200, the lifting platform 46 can be moved to the second position to allow the carrier 200 to move from the conveyor timing belt 14 to the return timing belt 44 or from the return timing belt 44 to the conveyor timing belt 14.

[0132] When the carrier 200 moves to the return synchronous belt 44, the lifting platform 46 can move to the first position, and the positioning platform can be positioned by inserting the positioning post 461 into the positioning hole 204. This can prevent the carrier 200 from deviating from the return synchronous belt 44 during the process of the return synchronous belt 44 driving the carrier 200 to move in the first direction, thereby ensuring that the carrier 200 can be transported normally afterwards.

[0133] For example, the third direction is the vertical direction, which is the Z-axis direction in the figure. A lifting platform 46 is located above the base frame 413 and between two adjacent return timing belts 44. The lifting drive 47 is a pneumatic cylinder. The cylinder base of the lifting drive 47 is bolted to the base frame 413, and the piston rod of the lifting drive 47 is arranged upward and connected to the lifting platform 46.

[0134] When the lifting platform 46 moves to the first position, the upper end height of the positioning post 461 is higher than the upper surface height of the return synchronous belt 44, so that the positioning post 461 can be inserted into the corresponding positioning hole 204. When the lifting platform 46 moves to the second position, the upper end height of the positioning post 461 is less than or equal to the upper surface height of the return synchronous belt 44, so that the positioning post 461 can be separated from the positioning hole 204.

[0135] like Figure 11 As shown, in one embodiment of the present application, the drive assembly 50 includes a fixed rack 51, a transverse drive motor 52, and a gear member 53. The fixed rack 51 is disposed on the frame 30 and extends along the first direction. The transverse drive motor 52 is bolted to the base frame 513. The gear member 53 is connected to the transverse drive motor 52, and the gear member 53 is engaged with the fixed rack 51 for transmission. Exemplarily, the transverse drive motor 52 is a servo motor, the gear member 53 is a gear box, and the fixed rack 51 is bolted to the frame 30.

[0136] The traverse drive motor 52 is used to drive the gear member 53 to rotate. Through the meshing transmission between the gear member 53 and the fixed rack 51, the gear member 53 can drive the traverse drive motor 52 and the return bracket 41 to move in the first direction, thereby driving the return timing belt 44 to move in the first direction. Furthermore, by driving the gear member 53 to rotate clockwise or counterclockwise by the traverse drive motor 52, the return timing belt 44 can reciprocate in the first direction.

[0137] It can be understood that the drive component 50 in this embodiment adopts a combination of gears and racks as the drive mechanism, and the cooperation of the transverse drive motor 52, the gear part 53 and the fixed rack 51 can achieve rapid response movement and improve the transportation efficiency of the carrier 200; in other embodiments, the drive component 50 can also adopt a screw slide as a drive mechanism, and this application does not limit this.

[0138] like Figure 11 As shown, in one embodiment of the present application, the rack 30 is provided with a plurality of slide rails 31 , which extend along a first direction and are bolted to the upper side of the rack 30 , and the plurality of slide rails 31 are spaced apart in a second direction.

[0139] The base frame 413 is provided with multiple sliders 48 that are compatible with the slide rails 31. The sliders 48 are bolted and fixed to the bottom of the base frame 413. The multiple sliders 48 are slidably connected to the multiple slide rails 31 one by one to achieve sliding cooperation between the base frame 413 and the frame 30 in the first direction, thereby improving the movement efficiency of the transfer component 40 in the first direction.

[0140] like Figure 2 、 Figure 3 、 Figure 7 and Figure 11 As shown, the following is an exemplary description of the working method of the return flow transport device 100 of this embodiment.

[0141] First, the fully loaded carrier 200 is placed on the loading station 101, and the first conveyor belt 14a carries the fully loaded carrier 200; the reflow belt 44 moves to the first reflow station 102, so that the reflow belt 44 is docked with the first conveyor belt 14a, and the lifting platform 46 is located at the second position.

[0142] Then, the first conveyor synchronous belt 14 a conveys the fully loaded carrier 200 to the first reflow station 102 , and the reflow synchronous belt 44 receives the fully loaded carrier 200 from the first conveyor synchronous belt 14 a .

[0143] Then, other equipment may move the materials in the carrier 200 away from the first reflow station 102 .

[0144] Then, the lifting platform 46 rises to the first position to position the empty carrier 200 carried on the return synchronous belt 44 .

[0145] Then, the driving assembly 50 drives the reflow timing belt 44 to move from the first reflow station 102 to the second reflow station 103 , so that the reflow timing belt 44 docks with the second conveying timing belt 14 b .

[0146] Then, the lifting platform 46 descends to the second position, and the synchronous belt 44 transports the empty carrier 200 to the second reflow station 103 .

[0149] It is worth noting that the number of the first conveying mechanism 10a in this application is taken as 1 as an example. In other embodiments, the first conveying mechanism 10a can also be set to multiple and distributed at intervals in the first direction; when there are multiple first conveying mechanisms 10a, there are also multiple first reflow stations 102. In this way, the reflow synchronous belt 44 can be moved to different first reflow stations 102 to receive carriers 200 from different first conveying mechanisms 10a. This is not limited in this application.

In other embodiments, the second conveying mechanisms 10b can also be set to multiple and distributed at intervals in the first direction; when there are multiple second conveying mechanisms 10b, there are also multiple second reflow stations 103. In this way, the reflow synchronous belt 44 can be moved to different second reflow stations 103 to put the carrier 200 into different second conveying mechanisms 10b. This is not limited in this application.
