Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic material processing, and in particular to a conveying mechanism and a reflux transport device. Background Art

[0002] Currently, the processing of semiconductor or photovoltaic materials typically requires multiple production lines to sequentially move materials to different workstations for processing, completing the corresponding loading and unloading operations. For example, during loading, a loading line transports a loaded carrier along with the material to a certain workstation, where another device can remove the material from the carrier for processing. During unloading, an unloading line transports an empty carrier to another workstation for retrieving it.

[0003] However, some workstations have requirements for the placement direction of the carrier. If the assembly line does not transport the carrier in the specified placement direction, it may cause the subsequent processes to fail to execute normally, affecting work efficiency. Utility Model Content

[0004] In view of the above, it is necessary to provide a conveying mechanism and a reflux transport device to improve work efficiency.

[0005] The first aspect of the present application provides a conveying mechanism for conveying a carrier, wherein a clearance groove is provided at the bottom of the carrier, the carrier has a first side and a second side arranged opposite to each other, and the clearance groove runs through the first side and the second side, and the conveying mechanism includes: a conveying bracket; a transmission assembly, which is arranged on the conveying bracket, and the transmission assembly is used to convey the carrier in a first direction; a stopper, which is connected to the conveying bracket, the stopper is adapted to the clearance groove, and the position of the stopper is located on the moving path of the carrier; when the carrier is placed on the transmission assembly and the clearance groove is parallel to the first direction, the stopper can move relatively in the clearance groove.

[0006] In some embodiments, the stopper is eccentrically arranged relative to the geometric center of the conveying bracket; when the carrier is placed on the transmission assembly, the clearance groove is parallel to the first direction, and the first side of the carrier is facing the outlet end of the transmission assembly, the stopper can move relatively in the clearance groove.

[0007] In some embodiments, the transmission assembly includes: a conveying drive member, which is arranged on a conveying bracket; a conveying drive wheel, which is connected to the conveying drive member; at least two conveying synchronous belts, which are transmission-connected to the conveying drive wheel and extend along a first direction; wherein, the block is located between two adjacent conveying synchronous belts, and the upper end height of the block is higher than the upper surface height of the conveying synchronous belt.

[0008] In some embodiments, the conveying mechanism also includes a check member, which is connected to the conveying bracket. The check member is located on the side of the conveying bracket close to the stop block, and the position of the check member is located on the moving path of the carrier; when the carrier moves past the check member in a direction away from the middle of the conveying bracket, the check member prevents the carrier from continuing to move by abutting against the side of the carrier.

[0009] In some embodiments, the conveying bracket is provided with a rotating seat, and the check member is connected to the rotating seat by rotating a shaft. One end of the check member is provided with a force-bearing end for contacting the carrier, and the check member has a blocking state and an avoidance state that are switched by rotation; when the check member is rotated to the blocking state, the position of the force-bearing end is located on the moving path of the carrier; when the check member is rotated to the avoidance state, the position of the force-bearing end is away from the moving path of the carrier.

[0010] In some embodiments, the rotating seat is provided with a positioning member, which is located on the side of the rotating shaft close to the middle of the conveying bracket; if the carrier moves toward the direction close to the middle of the conveying bracket and abuts the force-bearing end, the check member can rotate around the rotating shaft to an avoidance state; if the carrier moves toward the direction away from the middle of the conveying bracket and abuts the force-bearing end, the positioning member abuts the check member to maintain the check member in a blocking state.

[0011] In some embodiments, a counterweight end is provided at the end of the check member away from the force-bearing end, and the counterweight end is used to set the force-bearing end upward under the action of gravity; when the check member is in a blocking state, the height of the force-bearing end is higher than the upper surface height of the transmission assembly.

[0012] In some embodiments, the force-bearing end is provided with a relief surface, and the relief surface is inclined downward in a direction away from the middle of the delivery bracket.

[0013] In some embodiments, positioning ribs are provided on the circumferential side of the conveying drive wheel, and positioning grooves are provided on the inner side of the conveying synchronous belt. The conveying synchronous belt is sleeved on the conveying drive wheel, and the positioning ribs and the positioning grooves are positioned and matched in the second direction, wherein there is an angle between the first direction and the second direction.

[0015] The conveying mechanism and reflux transport device provided by this application are such that when a carrier is placed on a transmission assembly and the clearance groove deviates from a first direction, the block cannot move relative to the clearance groove, thereby preventing the block from passing through the clearance groove in the first direction. At this time, when the transmission assembly drives the carrier to move past the block, the block abuts against the side wall of the carrier to interfere with the position of the carrier, preventing the carrier from continuing to move. In this way, the block has the function of limiting the angle of the clearance groove, thereby preventing the placement angle of the carrier on the transmission assembly from being fooled, allowing only carriers placed at the appropriate angle to pass through, preventing the subsequent process from being abnormally executed due to the non-compliant placement angle of the carrier, thereby improving work efficiency.

[0028] The following specific implementation methods will further illustrate the present application in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0029] 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.

[0030] 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.

[0031] This application first provides a conveying mechanism. The conveying mechanism is used to convey a carrier. The carrier is used to load materials. The types of carriers and materials can be configured according to the actual application scenario. For example, the conveying mechanism provided in this embodiment can be applied to the ALD process. The carrier can be a carrier plate, and the material can be a sheet material such as a silicon wafer or a silicon carbide wafer used as a solar cell.

[0032] Figure 1 A schematic structural diagram of the bottom of the carrier provided in this application.

[0033] like Figure 1 As shown, 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 disposed opposite to each other, and the clearance groove 201 passes through the first side 202 and the second side 203 in a straight line.

[0034] Figure 2 This is a schematic structural diagram of the conveying mechanism of the first embodiment provided in this application.

[0035] like Figure 1 and Figure 2 As shown, the conveying mechanism 10 includes a conveying support 11 and a transmission assembly 12. The transmission assembly 12 is disposed on the conveying support 11. The transmission assembly 12 can carry the carrier 200 and can transport the carrier 200 in a first direction. Exemplarily, the first direction is parallel to the X-axis direction in the figure.

[0036] The transmission assembly 12 has an inlet and an outlet at its two ends, and the transmission assembly 12 can transport the carrier 200 from the inlet to the outlet. It is understood that the inlet and outlet of the transmission assembly 12 can be interchanged based on the first direction of the transmission assembly 12 and the transport destination. Furthermore, the position, length, first direction, etc. of the transmission assembly 12 can be configured based on the requirements of specific application scenarios, such as workstation design requirements and loading and unloading requirements.

[0037] Figure 3 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.

[0038] like Figure 2 and Figure 3As 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 located along the moving path of the carrier 200. The moving path of the carrier 200 is driven by the transmission assembly 12.

[0039] When the carrier 200 is placed on the transmission assembly 12 and the clearance slot 201 is parallel to the first direction, the stopper 15 can move relative to the clearance slot 201, allowing the stopper 15 to pass through the clearance slot 201 along the first direction. In this way, when the transmission assembly 12 drives the carrier 200 to move past the stopper 15, the stopper 15 passes through the bottom of the carrier 200 through the clearance slot 201, preventing interference between the stopper 15 and the carrier 200 and allowing the carrier 200 to continue moving.

[0040] Conversely, when the carrier 200 is placed on the transmission assembly 12 and the clearance slot 201 is deviated from the first direction, the stopper 15 cannot move relative to the clearance slot 201, so that the stopper 15 cannot pass through the clearance slot 201 in the first direction. In this case, when the transmission assembly 12 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, preventing the carrier 200 from moving further.

[0041] In this way, the stop 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 transmission component 12, 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, thereby improving work efficiency.

[0042] like Figure 2 and Figure 3 As shown, in this embodiment, the transmission assembly 12 is a synchronous belt assembly, and the transmission assembly 12 includes a conveyor drive member 121, a conveyor drive wheel 122, and a conveyor synchronous belt 123. The conveyor drive member 121 is disposed on the conveyor bracket 11, the conveyor drive wheel 122 is rotatably connected to the conveyor bracket 11, and the conveyor drive wheel 122 is connected to the conveyor drive member 121. The conveyor synchronous belt 123 is in transmission connection with the conveyor drive wheel 122 and extends along the first direction.

[0043] In practical applications, the upper surface of the conveying synchronous belt 123 can carry the carrier 200. When the conveying driving member 121 drives the conveying driving wheel 122 to rotate, the conveying driving wheel 122 drives the conveying synchronous belt 123 to work, so that the conveying synchronous belt 123 conveys the carried carrier 200 in the first direction.

[0044] Two ends of the conveying synchronous belt 123 form an inlet end and an outlet end, and the conveying synchronous belt 123 can convey the carrier 200 from the inlet end to the outlet end.

[0045] The conveying mechanism 10 of the present application conveys the carrier 200 via the conveying synchronous belt 123. 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.

[0046] In other embodiments, the transmission assembly 12 may also adopt equipment such as a gantry translation assembly, a manipulator assembly, etc., as long as it can achieve the effect of carrying and transporting the carrier 200, and this application does not impose any restrictions on this.

[0047] Exemplarily, the transport 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 a second direction, wherein the second direction is at an angle to the first direction. Exemplarily, the second direction is the Y-axis direction shown in the figure.

[0048] The first frame 111 and the second frame 112 are both extended along the first 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 first direction. The top surface height of the connecting rod 113 is less than the upper surface height of the conveying synchronous belt 123 to prevent the connecting rod 113 from interfering with the conveying of the carrier 200.

[0049] Exemplarily, there are multiple conveyor timing belts 123, which are spaced apart in the second direction. Multiple conveyor timing belts 123 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 the conveying process. Furthermore, a certain amount of space can be left between the multiple conveyor timing belts 123 for other structural arrangements, thereby improving space utilization. In this embodiment, the number of conveyor timing belts 123 is two, and the distance between the two conveyor timing belts 123 is configured to correspond to the width of the carrier 200. The first frame 111 and the second frame 112 are respectively arranged to correspond to the two conveyor timing belts 123.

[0050] Exemplarily, there are also multiple conveying drive wheels 122, and the position and number of the conveying drive wheels 122 correspond to the position and number of the conveying synchronous belts 123. The conveying drive wheels 122 are located at the ends of the conveying synchronous belts 123, and the conveying synchronous belts 123 are sleeved on the conveying drive wheels 122. In the example of this embodiment, each conveying synchronous belt 123 is provided with a conveying drive wheel 122 at both ends, and the number of conveying drive wheels 122 is four. The two conveying drive wheels 122 corresponding to one of the conveying synchronous belts 123 are respectively rotatably connected to the two ends of the first frame 111, and the two conveying drive wheels 122 corresponding to the other conveying synchronous belt 123 are respectively rotatably connected to the two ends of the second frame 112.

[0051] Exemplarily, the conveying drive member 121 is bolted to one end of the first frame 111. The conveying drive member 121 may be a servo motor, and the output shaft of the conveying drive member 121 is coaxially connected to the conveying drive wheel 122. In this embodiment, the first direction has a forward direction and a reverse direction. By driving the conveying drive wheel 122 in a clockwise or counterclockwise direction by the conveying drive member 121, the carrier 200 can be conveyed in the forward or reverse direction of the first direction.

[0052] Figure 4 This is a schematic structural diagram of the conveying drive wheel and conveying synchronous belt provided in this application.

[0053] like Figure 3 and Figure 4 As shown, in this embodiment, a transmission tooth groove is provided on the circumference of the conveying drive wheel 122, and a transmission tooth tooth adapted to the transmission tooth groove is provided on the inner side of the conveying timing belt 123. When the conveying drive wheel 122 rotates, the conveying timing belt 123 contacts the conveying drive wheel 122, 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 123 and reducing the risk of the conveying timing belt 123 slipping.

[0054] A positioning rib 1221 is provided on the circumference of the conveying drive wheel 122, and a positioning groove 1231 is provided on the inner side of the conveying synchronous belt 123 to match the positioning rib 1221. The positioning rib 1221 is positioned and matched with the positioning groove 1231. Exemplarily, the positioning rib 1221 is formed by protruding from the surface of the transmission tooth groove. The positioning ribs 1221 are distributed in an annular shape along the circumference of the conveying drive wheel 122, and the annular axis of the positioning rib 1221 is arranged parallel to the second direction, so that the positioning rib 1221 and the positioning groove 1231 are positioned and matched in the second direction.

[0055] When the conveying drive wheel 122 rotates, the conveying timing belt 123 contacts the conveying drive wheel 122, and the positioning rib 1221 is embedded in the positioning groove 1231, preventing the conveying timing belt 123 and the conveying drive wheel 122 from deviating in the second direction, thereby reducing the risk of the conveying timing belt 123 detaching from the conveying drive wheel 122.

[0056] like Figure 2 and Figure 3 As shown, in this embodiment, the stopper 15 is located between two adjacent conveyor timing belts 123, and the upper end of the stopper 15 is higher than the upper surface of the conveyor timing belts 123. 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.

[0057] When the carrier 200 is placed on the conveying synchronous belt 123 , the upper end of the stopper 15 protrudes from the upper surface of the conveying synchronous belt 123 to pass through the moving path of the carrier 200 driven by the conveying synchronous belt 123 .

[0058] like Figure 2 and Figure 3 As shown, in this embodiment, the clearance slot 201 is eccentrically disposed relative to the geometric center of the transport carrier 200 .

[0059] Specifically, the stopper 15 has an eccentric distance from the geometric center of the transport bracket 11 in the second direction, so that the clearance groove 201 deviates from the geometric center of the transport carrier 200. The dotted line A in the figure is a straight line passing through the geometric center of the transport bracket 11.

[0060] When the carrier 200 is placed on the conveyor timing belt 123, the clearance groove 201 is arranged parallel to the first 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 123 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 the stopper 15 from interfering with the carrier 200 and allowing the carrier 200 to continue moving.

[0061] Conversely, when the carrier 200 is placed on the conveyor belt 123 and the clearance groove 201 is offset from the first direction, or when the carrier 200 is placed on the conveyor belt 123 and the clearance groove 201 is parallel to the first 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 belt 123 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.

[0062] 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.

[0063] 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.

[0064] Figure 5 This is a schematic structural diagram of the conveying mechanism of the second embodiment provided in this application.

[0065] like Figure 1 and Figure 5 As shown, in this embodiment, 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 close to the stopper 15, and the position of the check member 16 is located on the moving path of the carrier 200.

[0066] 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.

[0067] It is understood that during the process of conveying the carrier 200 by the conveyor timing belt 123, the carrier 200 first moves from the inlet end of the conveyor timing belt 123 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 123. 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.

[0068] Figure 6 This is a schematic structural diagram of the non-return member, rotating seat and positioning member provided in this application.

[0069] like Figure 1 、 Figure 5 and Figure 6 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.

[0070] 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 .

[0071] 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.

[0072] For example, while the carrier 200 is moving from the entrance of the conveyor timing belt 123 to the middle of the conveyor support 11, the check member 16 can be switched 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 timing belt 123, the check member 16 can remain in a blocking state, preventing the carrier 200 from continuing to move. This allows the check member 16 to only stop carriers 200 that have already been transported by the conveyor timing belt 123, preventing the check member 16 from stopping carriers 200 that have just entered the conveyor timing belt 123.

[0073] 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 .

[0074] 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.

[0075] 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.

[0076] It can be understood that in the process of the carrier 200 moving from the entrance end of the conveyor synchronous belt 123 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.

[0077] When the carrier 200 moves from the middle of the conveying support 11 to the exit end of the conveying synchronous belt 123 , 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.

[0078] It can be understood that by utilizing the automatic state switching function of the check member 16, check members 16 can be set at both ends of the conveying bracket 11. The check member 16 will automatically switch to the avoidance state or the blocking state according to the moving direction of the carrier 200, thereby reducing the restrictions on the first direction and installation orientation of the conveying synchronous belt 123.

[0079] Exemplarily, the check member 16 is located between two adjacent conveyor timing belts 123. The rotation axis 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 force 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 123.

[0080] When the carrier 200 is placed on the conveyor belt 123 and the anti-return member 16 is in the blocking state, the force-bearing end 161 of the anti-return member 16 protrudes from the upper surface of the conveyor belt 123 to pass through the moving path of the carrier 200 driven by the conveyor belt 123 .

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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 .

[0087] An embodiment of the present application also provides a reflux transport device.

[0088] Figure 7 This is a schematic structural diagram of the reflux transport device provided in this application. Figure 8 This is a schematic diagram of the status of the return transport device provided in this application when transporting a carrier.

[0089] like Figure 7 and Figure 8 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 plurality of conveying mechanisms 10 are spaced apart in the second direction. 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 at least two conveying mechanisms 10 and transport material in the second direction between the at least two conveying mechanisms 10.

[0090] In this embodiment, the carrier 200 has a fully loaded state and an empty state, and the conveying mechanism 10 and the return mechanism 20 can both convey the carrier 200 in both states. When the carrier 200 is loaded with materials, the carrier 200 is in the fully loaded state; when the carrier 200 is not loaded with materials, the carrier 200 is in the empty state.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] Figure 9 This is a schematic diagram of the structure of the reflux mechanism provided in this application.

[0096] like Figure 7 、 Figure 8 and Figure 9 As shown, 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 the second direction and pass through the first reflow station 102 and the second reflow station 103.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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 second 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.

[0102] Similarly, the number of the second conveying mechanisms 10b in this application is taken as 1 as an example. In other embodiments, the second conveying mechanisms 10b can also be set to multiple and distributed at intervals in the second 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.

[0103] Figure 10 A schematic diagram of the structure of the transfer component provided for this application.

[0104] like Figure 8 and Figure 10As shown, in this embodiment, 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.

[0105] 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.

[0106] The return timing belt 44 is arranged corresponding to the conveyor timing belt 123. When the return timing belt 44 moves to a position aligned with the conveyor timing belt 123 in the first direction, the return timing belt 44 docks with the conveyor timing belt 123. At this time, a continuous timing belt is formed between the return timing belt 44 and the docked conveyor timing belt 123 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 123, and the conveyor timing belt 123 can transport the carrier 200 to the return timing belt 44.

[0107] 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 123 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 123 of the second conveyor mechanism 10b.

[0108] 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.

[0109] 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.

[0110] 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 belt 123. The first mounting bracket 411 and the second mounting bracket 412 are respectively arranged to correspond to the two return timing belts 44.

[0111] 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.

[0112] 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 123; when the carrier 200 moves in the reverse direction of the first direction, the carrier 200 can be conveyed from the conveying timing belt 123 to the reflux timing belt 44.

[0113] like Figure 7 and Figure 9 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 , and the lifting platform 46 is connected to the lifting drive 47 .

[0114] 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, each of which is angled relative to the third direction. When the return timing belt 44 needs to dock with the conveyor timing belt 123 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 123 to the return timing belt 44, or from the return timing belt 44 to the conveyor timing belt 123.

[0115] like Figure 7 and Figure 9 As shown, the third direction is illustratively 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.

[0116] In this embodiment, the drive assembly 50 includes a fixed rack 51, a traverse drive motor 52, and a gear 53. The fixed rack 51 is mounted on the frame 30 and extends along a first direction. The traverse drive motor 52 is bolted to the base frame 513. The gear 53 is connected to the traverse drive motor 52 and meshes with the fixed rack 51 for transmission. Exemplarily, the traverse drive motor 52 is a servo motor, the gear 53 is a gear box, and the fixed rack 51 is bolted to the frame 30.

[0117] 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.

[0118] 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.

[0119] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
