Technical Field

[0001] This application relates to the field of battery cell processing technology, and in particular to a transport device and an automated production line. Background Technology

[0002] In the production of solar cells, it is typically necessary to pick up sheet materials from the loading box and place them on a conveyor structure; this is the loading operation. Simultaneously, the sheet materials need to be removed from the conveyor structure and placed into the unloading box; this is the unloading operation. In related technologies, the loading box and the unloading box are two different devices, and the movement trajectory of the sheet materials is complex, making the automation process relatively complicated. Utility Model Content

[0003] In view of the above, it is necessary to provide a transport device and an automated production line that can simplify the movement trajectory of sheet materials during loading / unloading operations, thereby optimizing the automation process.

[0004] The first aspect of this application provides a transport device, comprising:

[0005] A conveying assembly, arranged along the conveying direction, is used to receive and convey sheet-like materials;

[0006] Material carrier, located on one side of the conveying assembly, is configured to carry complete sheet materials;

[0007] A gripping device is positioned above the conveying assembly and the material carrier;

[0008] The gripping device can grip sheet-like materials inside the material carrier and place them on the conveying assembly; and the gripping device can grip whole sheet-like materials on the conveying assembly and place them inside the material carrier.

[0009] In some embodiments, the transport device further includes:

[0010] Waste carrier, located on one side of the conveying assembly, is configured to carry incomplete sheet-like materials;

[0011] The gripping device is capable of gripping incomplete sheet-like materials on the conveying assembly and placing them in the waste carrier;

[0012] The conveying assembly includes a first conveyor, a second conveyor, and a third conveyor arranged sequentially along the conveying direction.

[0013] The material carrier and the waste carrier are positioned opposite each other on both sides of the second conveyor;

[0014] The material carrier, the second conveyor, and the waste carrier are arranged in a straight line.

[0015] In some embodiments, the conveying assembly includes a first conveyor, a second conveyor, and a third conveyor arranged sequentially along the conveying direction, and a material carrier is disposed on one side of the second conveyor; the second conveyor is provided with a main sensor, which is used to sense whether there is sheet material on the second conveyor.

[0016] The main sensor includes:

[0017] A position sensor, located at one end of the second conveyor near the first conveyor, is configured to detect the presence of sheet-like material in the second conveyor; and

[0018] An auxiliary sensor is located at one end of the second conveyor near the third conveyor and is configured to detect whether there is sheet-like material in the second conveyor.

[0019] The positioning sensor and the auxiliary sensor are set at intervals. When the positioning sensor and the auxiliary sensor are blocked by both ends of a sheet of material, the main sensor recognizes the sheet of material as intact.

[0020] When at least one of the positioning sensor and the auxiliary sensor is not blocked by both ends of the sheet material, the main sensor identifies the sheet material as incomplete.

[0021] In some embodiments, when the positioning sensor detects a sheet of material, the second conveyor transmits the sheet of material a preset distance along the conveying direction until the sheet of material blocks the auxiliary sensor; the preset distance is greater than or equal to the distance between the positioning sensor and the auxiliary sensor.

[0022] The positioning sensor and / or auxiliary sensor are movably connected to the second conveyor.

[0023] In some embodiments, the transport device further includes a regulating component, which includes:

[0024] Two alignment components are symmetrically arranged on both sides of the second conveying component along the alignment direction; the alignment direction is perpendicular to the conveying direction.

[0025] A aligning drive unit connects to two aligning elements and drives the two aligning elements to move closer or further away synchronously.

[0026] When the position sensor and auxiliary sensor are blocked at both ends of the sheet material, the alignment drive drives the two alignment components to move closer to each other synchronously, so that the alignment components move closer to and fit against the side of the sheet material.

[0027] In some embodiments, each preform is provided with one or more rollers on its top, the rollers being rotatably connected to the preform and configured to abut against the side of the sheet material.

[0028] During the process of the two alignment components being driven by the alignment drive to contact the sheet material, the second conveyor component decelerates or stops.

[0030] The third conveyor is equipped with an auxiliary sensor, which is used to sense whether there is sheet-like material on the third conveyor.

[0031] When the incoming material sensor detects that there is no sheet material on the first conveyor and the main sensor detects that there is no sheet material on the second conveyor, the gripping device can grip the sheet material in the material carrier and place it on the second conveyor.

[0032] When the incoming material sensor detects the presence of sheet material on the first conveyor, the main sensor detects the presence of sheet material on the second conveyor, the auxiliary sensor detects the presence of sheet material on the third conveyor, and there is sheet material upstream of the first conveyor, the gripping device can grip the complete sheet material on the second conveyor and place it in the material carrier.

[0033] In some embodiments, the material carrier includes:

[0034] Vehicle base;

[0035] Two or more uprights are connected vertically to the perimeter of the carrier base to form a receiving space for placing sheet materials; the receiving space is adapted to the complete sheet materials.

[0037] The drive component is connected to the support and is used to drive the movement of the support.

[0038] In some embodiments, the material carrier transport device further includes:

[0039] A connecting base is located on one side of the conveying assembly and extends perpendicular to the conveying direction;

[0040] The connecting base includes a placement station and a working station, which are arranged perpendicular to the conveying direction, with the working station close to the conveying component.

[0041] The material carrier can be placed on the connecting base and can move between the placement station and the working station.

[0042] In some embodiments, the waste carrier includes:

[0043] A waste base is disposed on one side of the conveying assembly and extends perpendicular to the conveying direction; the waste base includes a base plate and at least one side plate; the base plate is used to support incomplete sheet material; the size of the base plate is larger than the size of the sheet material; the side plate extends vertically upward from the edge of the base plate; the side plate is used to prevent incomplete sheet material from slipping off the waste carrier.

[0044] In some embodiments, the grasping device includes:

[0045] A lateral movement component is positioned above the conveying component and extends perpendicular to the conveying direction;

[0046] A lifting control component is located on one side of the conveying component and below the traverse component; the lifting control component extends perpendicular to both the conveying direction and the traverse component direction.

[0047] The suction cup assembly is located at the end of the lifting control assembly away from the lateral movement assembly; the suction cup assembly can move laterally between the conveying assembly, the material carrier, and the waste carrier, and can move up / down between the lateral movement assembly and one of the material carrier and the conveying assembly.

[0048] A second aspect of this application provides an automated production line, the automated production line comprising:

[0049] The transport device is configured to receive and transport the sheet material;

[0050] The processing device is configured to receive sheet material transported by the transport device and to process the sheet material.

[0051] The processing equipment includes at least one of the following: laser-assisted sintering equipment, testing and sorting machine, dicing machine and screen printing machine;

[0052] The transport equipment includes:

[0053] A conveying assembly, arranged along the conveying direction, is used to receive and convey sheet-like materials;

[0054] Material carrier, located on one side of the conveying assembly, is configured to carry complete sheet materials;

[0056] The gripping device can grip sheet-like materials inside the material carrier and place them on the conveying assembly; and the gripping device can grip whole sheet-like materials on the conveying assembly and place them inside the material carrier.

[0057] The transport device and automated production line provided in this application allow complete sheet materials to move only between the material carrier and the conveying components, simplifying the movement trajectory of the sheet materials during loading or unloading operations and thus optimizing the automation process of the transport device. Simultaneously, placing complete sheet materials within the same material carrier reduces the cost of the automated production line. Attached Figure Description

[0065] The following detailed description, in conjunction with the accompanying drawings, further illustrates this application. Detailed Implementation

[0066] In the description of the embodiments of this application, when an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an element centrally located simultaneously. When an element is considered to be "set" on another element, it can be directly set on the other element or there may be an element centrally located simultaneously. In this application, unless otherwise expressly specified and limited, the terms "installed," "connected," "attached," "fixed," etc., should be interpreted broadly. 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 a direct connection or an indirect connection through an intermediate medium; it can be a connection within two elements. For those skilled in the art, the specific meaning 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 based on the direction of the product in the actual use scenario.

[0067] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0068] Currently, in the production process of solar cells, it is typically necessary to pick up sheet-like materials from the loading box and place them on a conveyor structure; this is the loading operation. Simultaneously, it is also necessary to remove the complete sheet-like materials from the conveyor structure and place them into the unloading box; this is the unloading operation. In related technologies, the loading box and the unloading box are two different devices, and the movement trajectory of the sheet-like materials is complex, making the automation process relatively complicated.

[0069] Therefore, embodiments of this application provide a transportation device and an automated production line, which can simplify the movement trajectory of sheet materials and optimize the technical effect of the automation process.

[0070] Figure 1 A schematic diagram of the transport device 100 provided in this application.

[0071] like Figure 1 As shown, the transport device 100 can be applied to an automated production line 1 (such as...). Figure 3As shown in the diagram, the conveying device 100 is used to automatically transport sheet materials and can automatically switch between loading and unloading operations. The loading operation involves placing complete sheet materials onto the conveying device 100 when there is a shortage of material; the unloading operation involves grabbing and removing the accumulated complete sheet materials from the conveying device 100 when there is a buildup of material. The sheet materials are raw materials for solar cells, including but not limited to silicon wafers and silicon carbide wafers.

[0072] The transport device 100 includes a material carrier 10, a drive assembly 20, a conveying assembly 30, a sensing assembly 40, a gripping device 200, and a waste carrier 60. In at least one embodiment of this application, the transport device 100 detects the sheet material on the conveying assembly 30 using the sensing assembly 40, and performs a loading or unloading operation using the gripping device 200 based on the detection result. For example, when the sensing component 40 detects that there is no sheet material provided by the upstream process (such as the processing device 300) on the conveying component 30, the transport device 100 uses the gripping device 200 to grip the complete sheet material located in the material carrier 10 and place it on the conveying component 30, and then conveys it to the next device through the conveying component 30 to realize the loading operation of the transport device 100; when the sensing component 40 detects that there is sheet material provided by the processing device 300 on the conveying component 30 and there is a stockpile, the transport device 100 uses the gripping device 200 to grip the complete sheet material located on the conveying component 30 and place it in the material carrier 10 to realize the unloading operation of the transport device 100. At the same time, when the sheet material on the conveying component 30 is incomplete, the transport device 100 uses the gripping device 200 to grip the incomplete sheet material on the conveying component 30 and place it in the waste carrier 60. In at least one embodiment of this application, the material carrier 10, the conveying assembly 30, the sensing assembly 40, and the waste carrier 60 can communicate with each other via wired or wireless means to achieve signal transmission. In other embodiments, the transport device 100 may further include a processor (not shown), which can be connected to the material carrier 10, the conveying assembly 30, the sensing assembly 40, and the waste carrier 60 simultaneously, and realize signal transmission between the material carrier 10, the conveying assembly 30, the sensing assembly 40, and the waste carrier 60.

[0073] The material carrier 10, the conveying assembly 30, and the waste carrier 60 are placed sequentially along a first direction X (horizontal direction) in the same horizontal plane. That is, in the first direction X, the conveying assembly 30 is located between the material carrier 10 and the waste carrier 60. The conveying assembly 30 can convey along a second direction Y, which is perpendicular to the first direction X. The plane containing the first direction X and the second direction Y is positioned as a horizontal plane. The material carrier 10 can move along a third direction Z (vertical direction). That is, the third direction Z is the direction of movement of the material carrier 10. The third direction Z is perpendicular to both the first direction X and the second direction Y. The first direction X, the second direction Y, and the third direction Z are mutually perpendicular to each other, forming a Cartesian coordinate system.

[0074] The material carrier 10 is used to carry and contain multiple complete sheet materials, and to drive the contained complete sheet materials to move up / down along a third direction Z. The material carrier 10 includes a connecting base 11 and a carrier base 12. The drive assembly 20 includes a material drive component 21. The material drive component 21, the connecting base 11, and the carrier base 12 are placed sequentially from bottom to top along a third direction Z.

[0075] The connecting base 11 is used to connect the carrier base 12 and the material drive unit 21. The connecting base 11 is disposed on one side of the conveying assembly 30 and extends perpendicular to the conveying direction. The connecting base 11 includes a placement station 111 and a working station 112. The placement station 111 and the working station 112 are arranged perpendicular to the conveying direction, and the working station 112 is close to the conveying assembly 30.

[0076] The carrier base 12 is movably placed on the connecting base 11 and can move along the first direction X between the placement station 111 and the working station 112, and can move relative to the material drive member 21 along the third direction Z. In at least one embodiment of this application, the carrier base 12 serves as the working station 112 when it is placed directly above the material drive member 21. The carrier base 12 can move away from the conveying assembly 30 along the first direction X under the action of an external force, that is, the carrier base 12 moves to the placement station 111. At this time, complete sheet materials can be placed into the carrier base 12 or the carrier base 12 filled with complete sheet materials can be removed from the transport device 100. When the carrier base 12 is in the working station 112, the complete sheet materials located in the carrier base 12 can move up / down along the third direction Z under the drive of the material drive member 21. The carrier base 12 includes a support part 121 and a plurality of columns 122.

[0077] The support portion 121 is generally flat. The support portion 121 is used to support the complete sheet material contained in the carrier base 12, and can move along the third direction Z between the initial position and the pick-up / placement position (not shown in the figure).

[0078] Multiple columns 122 extend in a third direction (Z) and connect to the periphery of the carrier base 12. The multiple columns 122 are evenly arranged around the edge of the support portion 121. The columns 122 extend in a third direction (Z) away from the support portion 121. A predetermined interval exists between adjacent columns 122. The columns 122 limit the movable range of the support portion 121 and the complete sheet material in the horizontal plane. The multiple columns 122 cooperate to form a receiving space 101. The receiving space 101 is generally a hollow cuboid for receiving the complete sheet material. In at least one embodiment of this application, the dimensions of the receiving space 101 match the dimensions of the complete sheet material.

[0079] The material drive unit 21 is used to drive the support unit 121 to move along the third direction Z between an initial position and a pick-up / place position. In the third direction Z, the material drive unit 21 is located below the working station 112 of the connecting base 11. In at least one embodiment of this application, the transport device 100 is also equipped with a human-machine interface (not shown), and the material drive unit 21 can drive the support unit 121 to move up / down along the third direction Z according to the user's operation within the human-machine interface.

[0080] The material drive unit 21 can also drive the support part 121 back to the initial position when the complete sheet material contained in the carrier base 12 reaches the full state. In at least one embodiment of this application, it is determined whether the complete sheet material contained in the carrier base 12 has reached the full state by detecting whether the distance between the current position of the support part 121 and the reference position (the support part 121 is in the pick-up and put-down position) is greater than a preset distance.

[0081] The transport device 100 can also generate a material full indication when the complete sheet material contained in the carrier base 12 reaches full. In at least one embodiment of this application, the material full indication can be given in the form of sound, image, light, or any combination of two or more.

[0082] The material carrier 10 also includes a slitting assembly 14, a position sensor 15, a lifting position sensor 16, and a component sensor 17.

[0083] The sheet-separating assembly 14 is disposed at the end of at least one column 122 near the pick-and-place position. The sheet-separating assembly 14 is used to separate a complete sheet of material located at the pick-and-place position from other complete sheet of material located below it during a feeding operation, ensuring that the gripping device 200 can only grip one complete sheet of material at a time. In at least one embodiment of this application, the sheet-separating assembly 14 is an air-blowing separation structure, which generates a flat airflow to separate multiple stacked complete sheet of material in layers.

[0084] Please see Figure 2This is a perspective view of the material carrier 10 from another angle. A position sensor 15 is disposed at the end of the connecting base 11 near the conveying assembly 30. The position sensor 15 is used to sense whether the carrier base 12 is located at the working station 112. When the position sensor 15 is obscured by the carrier base 12, the position sensor 15 senses that the carrier base 12 is located at the working station 112 and generates a position sensing signal; when the position sensor 15 is not obscured by the carrier base 12, the position sensor 15 identifies that the carrier base 12 is deviating from the working station 112 and generates a position anomaly signal. In at least one embodiment of this application, when the carrier base 12 is entirely placed directly above the material drive member 21, the position sensor 15 generates a position sensing signal. When the carrier base 12 is deviated from directly above the material drive member 21 or partially located directly above the material drive member 21, the position sensor 15 generates a position anomaly sensing signal.

[0085] A lifting position sensor 16 is disposed at the end of two opposing columns 122 away from the connecting base 11. In the horizontal plane, the lifting position sensor 16 is at the same horizontal plane as the pick-and-place position. The lifting position sensor 16 is used to identify whether a complete sheet of material or a support portion 121 exists at the pick-and-place position during loading or unloading operations. During loading operations, when the lifting position sensor 16 is obscured by a complete sheet of material, it generates a lifting position sensing signal, indicating that the gripping device 200 can grip the complete sheet of material within the material carrier 10. In at least one embodiment of this application, the lifting position sensor 16 is a through-beam sensor.

[0086] A component sensor 17 is disposed below the support portion 121. In at least one embodiment of this application, the light emitted by the component sensor 17 passes through a through-hole (not shown) in the support portion 121 and enters the carrier base 12. The component sensor 17 is used to sense whether a complete sheet of material exists within the carrier base 12. When a complete sheet of material is detected within the carrier base 12, the component sensor 17 outputs a material presence signal; when no complete sheet of material is detected within the carrier base 12, the component sensor 17 outputs a support portion presence signal. In at least one embodiment of this application, the component sensor 17 is a diffuse reflection photoelectric sensor.

[0087] A conveying assembly 30 is disposed between the material carrier 10 and the waste carrier 60, and can convey materials along the second direction Y. That is, the conveying direction of the conveying assembly 30 is perpendicular to the moving direction of the material carrier 10. In at least one embodiment of this application, the conveying assembly 30 includes a first conveying member 31a, a second conveying member 31b, and a third conveying member 31c. The first conveying member 31a, the second conveying member 31b, and the third conveying member 31c are arranged sequentially along the second direction Y. The first conveying member 31a is used to receive sheet material provided by the processing device 300; the second conveying member 31b is used to receive sheet material conveyed by the first conveying member 31a or placed by the gripping device 200; and the third conveying member 31c is used to receive complete sheet material conveyed by the second conveying member 31b. In other embodiments, the conveying assembly 30 may include more conveying members 31. The second conveying member 31b is disposed between the material carrier 10 and the waste carrier 60. That is, in the first direction X, the material carrier 10, the second conveyor 31b, and the waste carrier 60 are arranged in a straight line. In at least one embodiment of this application, the first conveyor 31a, the second conveyor 31b, and the third conveyor 31c are conveyor belts.

[0088] The drive assembly 20 also includes a first transmission drive 22, a second transmission drive 23, and a third transmission drive 24.

[0089] The first conveying drive 22 is used to drive the first conveyor 31a to move along the conveying direction when the sensing component 40 senses the presence of sheet material on the first conveyor 31a and the absence of sheet material on the second conveyor 31b. The conveying direction is the direction in which the first conveyor 31a moves towards the second conveyor 31b.

[0090] The second conveying drive 23 is used to drive the second conveyor 31b to move synchronously with the first conveyor 31a along the conveying direction when the sensing component 40 senses that there is sheet material on the first conveyor 31a and there is no sheet material on the second conveyor 31b, and is also used to drive the second conveyor 31b to move along the conveying direction when the sensing component 40 senses that there is sheet material on both the first conveyor 31a and the second conveyor 31b.

[0091] The third conveying drive 24 is used to drive the third conveyor 31c to move synchronously with the second conveyor 31b along the conveying direction when the sensing component 40 senses that there is a complete sheet material on the second conveyor 31b and there is no sheet material on the third conveyor 31c. It is also used to stop driving the third conveyor 31c to move along the conveying direction when the sensing component 40 senses that there is a complete sheet material on both the second conveyor 31b and the third conveyor 31c.

[0092] Please refer to the following: Figure 3The drive assembly 20 also includes a straightening assembly 25. The straightening assembly 25 includes two straightening members 251 and a straightening drive member 252. The two straightening members 251 are symmetrically arranged on both sides of the second conveyor 31b. The straightening members 251 are movable along a straightening direction, which is parallel to the first direction X and perpendicular to the conveying direction. At least one roller 2512 is provided on the top of each straightening member 251. In at least one embodiment of this application, each straightening member 251 is provided with four rollers 2512. The axial direction of the rollers 2512 is parallel to the third direction Z. The rollers 2512 are rotatably connected to the straightening members 251 and are used to abut against the sides of the sheet material. The straightening drive member 252 drives the two straightening members 251 to move along the straightening direction to fine-tune the position of the sheet material on the second conveyor 31b. The alignment drive 252 drives the two alignment members 251 to move synchronously closer to or farther away from the second conveyor 31b. At the same time, the second conveyor drive 23 drives the second conveyor 31b to decelerate or stop moving.

[0093] The sensing component 40 is disposed within the conveying component 30 and is used to sense whether there is sheet material on the conveying component 30. The sensing component 40 includes an incoming material sensor 41, a main sensor 42, and an auxiliary sensor 43.

[0094] A material receiving sensor 41 is disposed within the first conveyor 31a. The material receiving sensor 41 is used to sense whether sheet material is present on the first conveyor 31a. When no sheet material is detected on the first conveyor 31a, the first conveyor 31a does not receive sheet material from the upstream process (e.g., processing device 300), and the material receiving sensor 41 generates a feeding control signal. When sheet material is detected on the first conveyor 31a, the first conveyor 31a receives sheet material from the processing device 300.

[0095] Please refer to the following: Figure 4 The main sensor 42 is disposed within the second conveyor 31b. The main sensor 42 is used to sense whether there is sheet-like material on the second conveyor 31b. When the incoming material sensor 41 detects that there is no material on the first conveyor 31a, and the main sensor 42 detects that there is no sheet-like material on the second conveyor 31b, the conveying device 100 is identified as being in an unloaded state, and the conveying device 100 can generate a feeding control signal; when sheet-like material is detected on the second conveyor 31b, the main sensor 42 further detects the integrity of the sheet-like material on the second conveyor 31b. Figure 4As shown, the main sensing element 42 includes at least one position sensor 421 and at least one auxiliary sensor 422. The position sensor 421 and the auxiliary sensor 422 are arranged sequentially along the second direction Y and are movably connected to the second conveyor 31b. Specifically, the position sensor 421 is located at the end of the second conveyor 31b near the first conveyor 31a, and the auxiliary sensor 422 is located at the end of the second conveyor 31b near the third conveyor 31c. Both the position sensor 421 and the auxiliary sensor 422 are located in the middle of the second conveyor 31b and are arranged adjacent to each other. The position sensor 421 is used to detect whether there is sheet-like material on the second conveyor 31b. When the position sensor 421 detects sheet-like material, the second conveyor 31b transports the sheet-like material a preset distance along the conveying direction until the sheet-like material blocks the auxiliary sensor 422. The preset distance is greater than or equal to the distance between the position sensor 421 and the auxiliary sensor 422. The auxiliary sensor 422 is used to assist in detecting whether the sheet material on the second conveyor 31b is intact. In at least one embodiment of this application, when both the positioning sensor 421 and the auxiliary sensor 422 are blocked, the main sensor 42 identifies the sheet material on the second conveyor 31b as intact; when at least one of the positioning sensor 421 and the auxiliary sensor 422 is not blocked by both ends of the sheet material, the main sensor 42 identifies the sheet material on the second conveyor 31b as incomplete. That is, when the intact sheet material is placed on the second conveyor 31b, both the positioning sensor 421 and the auxiliary sensor 422 are blocked by both ends of the sheet material. At this time, the alignment drive 252 drives the two alignment members 251 to move closer synchronously, so that the alignment members 251 move closer to and fit against the side of the sheet material. In at least one embodiment of this application, the incoming material sensor 41 and the auxiliary sensor 43 also include at least one positioning sensor 421 and at least one auxiliary sensor 422.

[0096] The waste carrier 60 is used to collect incomplete sheet materials and count the collected broken sheet materials, and generates a waste removal prompt when the collected incomplete sheet materials reach the waste upper limit threshold. In at least one embodiment of this application, the waste removal prompt can be given in the form of sound, image, light, or any combination of two or more.

[0097] The waste carrier 60 includes a waste base 61, a waste connecting base 62, a waste full sensor 63, and a waste arrival sensor 65. The waste base 61 is used to receive incomplete sheet materials. The waste base 61 is located on one side of the second conveyor 31b and is symmetrically arranged on both sides of the second conveyor 31b with the carrier base 12. The waste base 61 is movably placed on the waste connecting base 62. Specifically, the waste base 61 can be located at the loading station 601 to receive incomplete sheet materials; it can also be moved in a first direction away from the conveying assembly 30 to remove the waste base 61 filled with incomplete sheet materials from the transport device 100, thereby replacing it with an empty waste base 61. The waste base 61 includes a base plate 611 and at least one side plate 612. In at least one embodiment of this application, the size of the base plate 611 is larger than the size of the sheet materials. The base plate 611 is generally rectangular. A notch 613 is provided on the side of the base plate 611 away from the conveying assembly 30. The notch 613 allows incomplete sheet material in the waste base 61 to fall onto the waste connecting base 62. A side plate 612 extends vertically upward from the edge of the base plate 611. The side plate 612 prevents incomplete sheet material from sliding off the side and falling outside the waste carrier 60. The waste connecting base 62 supports the waste base 61 and can also support incomplete sheet material. A waste full sensor 63 may be disposed on the side plate 612. The waste full sensor 63 is used to identify that the waste base 61 is full when it is obstructed and generates a waste full indication. In at least one embodiment of this application, the waste full indication may be in the form of sound, image, light, or any combination of two or more. A waste position sensor 65 is used to sense whether the waste base 61 is located at the loading station 601. When the waste material arrival sensor 65 is blocked by the waste material base 61, the waste material arrival sensor 65 identifies that the waste material base 61 is located at the loading station 601 and generates a waste material carrier arrival signal; when the waste material arrival sensor 65 is not blocked by the waste material base 61, the waste material arrival sensor 65 identifies that the waste material base 61 is deviated from the loading station 601 and generates a waste material carrier abnormality signal.

[0098] The gripping device 200 is located above the plane containing the material carrier 10, the conveying assembly 30, the sensing assembly 40, and the waste carrier 60. The gripping device 200 can move from its original position along a first direction X and a third direction Z to move between the material carrier 10, the conveying assembly 30, and the waste carrier 60, thereby gripping and moving sheet materials. During loading operations, the gripping device 200 can grip the sheet materials in the material carrier 10 and place them on the conveying assembly 30. During unloading operations, the gripping device 200 can grip the complete sheet materials on the conveying assembly 30 and place them on the material carrier 10. During waste removal operations, the gripping device 200 grips the incomplete sheet materials on the conveying assembly 30 and places them on the waste carrier 60. In at least one embodiment of this application, the original position can be the position where the gripping device 200 is directly above the second conveyor 31b. In other embodiments, the original position can also be the position where the gripping device 200 is directly above the waste carrier 60. The gripping device 200 includes a lateral movement component 201, a lifting control component 202, and a suction cup component 203.

[0099] The lateral movement assembly 201 is positioned across the material carrier 10, the second conveyor 31b, and the waste carrier 60. The lateral movement assembly 201 controls the lifting control assembly 202 and the suction cup assembly 203 to move along the first direction X, and controls the suction cup assembly 203 to remain above any one of the material carrier 10, the second conveyor 31b, and the waste carrier 60.

[0100] The lifting control component 202 is disposed on the traversing component 201 and can move synchronously with the traversing component 201. The lifting control component 202 is used to control the suction cup component 203 to move upward or downward along the third direction Z. In at least one embodiment of this application, the lifting control component 202 is a cylinder structure.

[0101] The suction cup assembly 203 is disposed at the end of the lifting control assembly 202 away from the lateral movement assembly 201, and can move along the first direction X under the drive of the lateral movement assembly 201, and move up / down along the third direction Z under the drive of the lifting control assembly 202. The suction cup assembly 203 is used to grasp or release sheet-like materials. In at least one embodiment of this application, the suction cup assembly 203 is a Bernoulli suction cup. The suction cup assembly 203 includes at least one suction cup pressure gauge 2031 and at least one suction cup portion 2032. One suction cup portion 2032 corresponds to one suction cup pressure gauge 2031. In at least one embodiment of this application, the suction cup assembly 203 includes one suction cup pressure gauge 2031 and one suction cup portion 2032. In other embodiments, the suction cup assembly 203 may include a suction cup portion 2032 and a plurality of suction cup pressure gauges 2031, and the arrangement of the plurality of suction cup pressure gauges 2031 is not limited herein. The suction cup pressure gauge 2031 is located above the corresponding suction cup part 2032 and is mounted on the lifting control assembly 202. The suction cup pressure gauge 2031 is used to detect the pressure inside the corresponding suction cup part 2032 in real time and determine whether the suction cup part 2032 has completed the gripping operation based on the detected pressure. The suction cup part 2032 is located at the end of the lifting control assembly 202 furthest from the horizontal movement assembly 201.

[0102] The working principle of the transport device 100 is as follows:

[0103] The loading operation of the transport device 100 may include material source detection, lifting, handling, positioning, and waste material lateral movement. In other embodiments, the above-mentioned multiple operations may be combined or split as needed.

[0104] Specifically, the process for material source detection is as follows:

[0105] When the incoming material sensor 41 detects that there is no sheet material on the first conveyor 31a, and the main sensor 42 detects that there is no sheet material on the second conveyor 31b, the incoming material sensor 41 identifies that the transport device 100 has not received any externally flowing sheet material and is in an unloaded state. The incoming material sensor 41 and / or the main sensor 42 generate a feeding control signal.

[0106] The specific process of the lifting operation is as follows:

[0107] A carrier base 12 loaded with sheet material is placed on a connecting base 11. A position sensor 15 generates a positioning sensing signal when it senses that the carrier base 12 is at the working station 112. Simultaneously, a component sensor 17 generates a material presence sensing signal when it senses the presence of sheet material within the carrier base 12. The material drive 21 drives the support 121 to move upward along the third direction Z based on the positioning sensing signal, the material presence sensing signal, and the loading control signal, thereby moving the sheet material from its initial position to the pick-up / placement position. Upon receiving a lifting positioning sensing signal, the material drive 21 stops driving the support 121. At this time, the sheet material at the top of the carrier base 12 is in the pick-up / placement position. The sheet separation assembly 14 separates the sheet material in the pick-up / placement position from other sheet materials. When a vacuum is formed between the suction cup assembly 203 and the sheet material, the material drive 21 drives the support 121 to move downward along the third direction Z, thereby moving the sheet material downward. At this time, the support 121 moves downward a specified distance from its current position, ensuring that the gripping device 200 only grips the uppermost sheet material within the carrier base 12. After moving the specified downward distance, the material drive 21 again drives the support 121 to move upward along the third direction Z, thereby moving the next sheet material to the pick-up / placement position. Upon receiving a lifting-to-position sensing signal, the material drive 21 stops driving the support 121. At this time, the next sheet material within the carrier base 12 is lifted to the pick-up / placement position, awaiting the next gripping operation of the gripping device 200. In at least one embodiment of this application, the specified downward distance is 5 millimeters (mm).

[0108] The handling process is as follows:

[0109] When neither the incoming material sensor 41 nor the main sensor 42 detects any sheet material, the lateral movement component 201 in the gripping device 200 controls the lifting control component 202 and the suction cup component 203 to move along the first direction X, and stops moving when they reach directly above the pick-up / placement position. The lifting control component 202 controls the suction cup component 203 to move along the third direction Z and descend to the pick-up / placement position. The suction cup component 203 performs a vacuuming operation to tightly bind the suction cup component 203 to the sheet material, thereby achieving the gripping of the sheet material in the carrier base 12. When a vacuum is formed between the suction cup component 203 and the sheet material, the lifting control component 202 rises to move the suction cup component 203 upwards along the third direction Z by a first safe distance. Then, the lateral movement component 201 moves the lifting control component 202 and the suction cup component 203 above the second conveyor 31b. After rising a first safe distance along the third direction Z, the suction cup assembly 203 is positioned above the plane where the pick-up and place position is located, ensuring that the suction cup assembly 203 will not collide with the material carrier 10 during its movement along the first direction X. When the lateral movement assembly 201 drives the lifting control assembly 202 and the suction cup assembly 203 to be above the second conveyor 31b, the lifting control assembly 202 drives the suction cup assembly 203 to move down to the material placement position on the second conveyor 31b, and the suction cup assembly 203 performs a vacuum breaking operation to place the adsorbed sheet material onto the second conveyor 31b.

[0110] The positioning operation process is as follows:

[0111] When the main sensor 42 senses the presence of sheet material on the second conveyor 31b, the main sensor 42 further detects the integrity of the sheet material. When both the positioning sensor 421 and the auxiliary sensor 422 are blocked by the two ends of the sheet material, the main sensor 42 identifies the integrity of the sheet material on the second conveyor 31b and generates a regularization control signal. The regularization drive 252 drives the two regularization members 251 to move closer synchronously, so that the regularization members 251 approach and conform to the side of the sheet material, thereby adjusting the position of the sheet material on the second conveyor 31b from the first direction X. The conveying assembly 30 can improve the positioning accuracy of the sheet material on the second conveyor 31b through a secondary positioning operation. The conveying assembly 30 uses the regularization members 25 to locate the edge position of the sheet material from the first direction X, further improving the positioning accuracy of the sheet material on the second conveyor 31b.

[0112] The process of waste material lateral movement is as follows:

[0113] When at least one of the positioning sensor 421 and the auxiliary sensor 422 is not obstructed by both ends of the sheet material, the main sensor 42 identifies that the sheet material on the second conveyor 31b is incomplete. The lateral movement component 201 controls the lifting control component 202 and the suction cup component 203 to move along the first direction X and stop moving when they reach directly above the second conveyor 31b. The lifting control component 202 controls the suction cup component 203 to move along the third direction Z and descend to the unloading position. At this time, the suction cup component 203 comes into contact with the sheet material on the second conveyor 31b. The suction cup component 203 performs a vacuuming operation to tightly bind the suction cup component 203 to the sheet material, thereby achieving the gripping of the sheet material on the second conveyor 31b. When a vacuum is formed between the suction cup component 203 and the sheet material, the suction cup component 203 moves along the first direction X under the drive of the lateral movement component 201 and is positioned above the waste carrier 60. When the waste arrival sensor 65 detects that the waste base 61 is located at the loading station 601, the suction cup assembly 203 performs a vacuum breaking operation to place the adsorbed sheet material into the waste carrier 60. After the vacuum breaking operation is completed, the gripping device 200 returns to its original position to achieve reset.

[0114] The unloading operation of the transport device 100 may include fault detection, handling, material loading, and full-load detection. In other embodiments, these multiple operations may be combined or split as needed.

[0115] Specifically, the material feeding process is as follows:

[0116] When the incoming material sensor 41 detects the presence of sheet material on the first conveyor 31a, the main sensor 42 detects the presence of complete sheet material on the second conveyor 31b, and the auxiliary sensor 43 detects the presence of complete sheet material on the third conveyor 31c, at least one of the incoming material sensor 41, the main sensor 42, and the auxiliary sensor 43 generates a feeding control signal, and the conveying device 100 switches to feeding mode.

[0117] The handling process is as follows:

[0118] When the receiving sensor 41 detects sheet material on the first conveyor 31a, the main sensor 42 detects a complete sheet material on the second conveyor 31b, and the auxiliary sensor 43 detects a complete sheet material on the third conveyor 31c, the lateral movement component 201 in the gripping device 200 controls the lifting control component 202 and the suction cup component 203 to move along the first direction X, and stops moving when they reach directly above the second conveyor 31b. The lifting control component 202 controls the suction cup component 203 to move along the third direction Z and descend to the material release position. The suction cup component 203 performs a vacuuming operation to tightly bind the suction cup component 203 with the complete sheet material, thereby achieving the gripping of the complete sheet material on the second conveyor 31b. When a vacuum is formed between the suction cup component 203 and the complete sheet material, the lifting control component 202 moves up a second safety distance along the third direction Z. In this embodiment, after moving upwards a second safety distance along the third direction Z, the suction cup assembly 203 is positioned above the plane of the pick-up / placement position, ensuring that the suction cup assembly 203 will not collide with the material carrier 10 during its movement along the first direction X. In at least one embodiment of this application, the second safety distance is greater than the first safety distance. That is, during the unloading operation, the distance the suction cup assembly 203 moves upwards along the third direction Z from the unloading position is greater than the distance the suction cup assembly 203 moves upwards along the third direction Z from the pick-up / placement position during the loading operation. After moving upwards a second safety distance along the third direction Z, the lateral movement assembly 201 moves the lifting control assembly 202 and the suction cup assembly 203 with the complete sheet material adsorbed to a position above the pick-up / placement position of the material carrier 10. At this time, the lifting control assembly 202 lowers the suction cup assembly 203 with the complete sheet material adsorbed until it reaches the pick-up / placement position. When the suction cup assembly 203, which has adsorbed complete sheet material, reaches the pick-up / placement position, it performs a vacuum breaking operation to place the adsorbed complete sheet material into the carrier base 12. After the vacuum is broken between the suction cup assembly 203 and the complete sheet material, the suction cup assembly 203 moves a safe distance upwards along the third direction (Z) from the pick-up / placement position. Then, the lateral movement assembly 201 drives the lifting control assembly 202 and the suction cup assembly 203 back to their original positions to achieve reset.

[0119] The material loading process is as follows:

[0120] The carrier base 12 is placed on the connecting base 11. The position sensor 15 generates a positioning sensing signal when it senses that the carrier base 12 is located at the working station 112. At the same time, the material drive 21 drives the support part 121 to move upward along the third direction Z according to the positioning sensing signal and the unloading control signal. When the lifting positioning sensing signal is received, the material drive 21 stops driving the support part 121. At this time, the support part 121 or the complete sheet material supported by the support part 121 is in the pick-up and place position to support the complete sheet material released by the gripping device 200. When the vacuum is broken between the suction cup assembly 203 and the complete sheet material, the material drive 21 drives the support part 121 to move downward along the third direction Z to move the complete sheet material downward. At this time, the support part 121 moves downward a specified distance from its current position. After moving downward a specified distance, the material drive 21 drives the support part 121 to move upward along the third direction Z again to move the complete sheet material to the pick-up and place position. Upon receiving the lifting-in-position sensing signal, the material drive unit 21 stops driving the support unit 121. In this way, the material carrier 10 completes one loading operation and ensures that the complete sheet material released by the gripping device 200 is placed on top of the carrier base 12 when performing the next loading operation, thereby reducing the risk of sheet material breakage during the unloading operation.

[0121] The process for full material detection is as follows:

[0122] The transport device 100 uses a processor to identify the position of the support 121 when the lifting sensor 16 is blocked by the support 121, using this position as a reference position. It also detects in real time whether the distance between the current position of the support 121 and the reference position is greater than a set distance. In at least one embodiment of this application, the processor of the transport device 100 can accumulate the number of times the support 121 performs a downward movement, calculate the distance between the current position of the support 121 and the reference position as the descent distance based on the accumulated number of movements, and determine whether the descent distance is greater than the set distance. In other embodiments, the transport device 100 can also use a distance sensor to obtain the reference position and the current position of the support 121, and calculate the difference between the two to obtain the descent distance, but is not limited to this. In at least one embodiment of this application, the set distance is 40 mm. When the descent distance of the support 121 is greater than or equal to the set distance, the transport device 100 identifies that the number of complete sheet materials contained in the carrier base 12 has reached a preset value, the containing space 101 is full of complete sheet materials, and drives the support 121 back to its initial position. At the same time, the transport device 100 can also generate a material full indication.

[0123] The aforementioned transport device 100 automatically switches between loading and unloading operations by using a sensing component 40 to detect the presence of complete sheet materials on the conveying component 31. Both loading and unloading operations utilize the same carrier base 12 to hold the complete sheet materials, improving the automation level of the loading / unloading operations. Secondly, the receiving space 101 within the material carrier 10 is adapted to the complete sheet materials, and the column 122, the lifting positioning sensor 16, and the segmenting component 14 work together to limit, detect, and segment the complete sheet materials. Compared to the simpler waste carrier 60, the material carrier 10 has higher placement accuracy. Furthermore, the complete sheet materials removed during the unloading operation and held in the carrier base 12 can be placed on the conveying component 31 during subsequent loading operations, reducing the number of transfers and improving the handling efficiency of the sheet materials. Additionally, the positioning sensor 421 and auxiliary sensor 422 work together to detect the integrity of the sheet materials on the second conveying component 31b. The second conveyor 31b performs secondary positioning during the conveying process, ensuring that each sheet material is in the same position when it moves onto the second conveyor 31b, thereby achieving precise control over the position of the sheet materials during automation. The straightening component 25 fine-tunes the position of the sheet materials on the second conveyor 31b along the straightening direction to further improve the accuracy of ensuring that each sheet material is in the same position on the second conveyor 31b.

The automated production line 1 includes a transport device 100, a gripping device 200, a processing device 300, and a controller 400. The gripping device 200 is located above the plane containing the material carrier 10, the conveying assembly 30, and the waste carrier 60, and is movable along a first direction X and a third direction Z to transport and move sheet materials between the material carrier 10, the conveying assembly 30, and the waste carrier 60. In at least one embodiment of this application, the processing device 300 includes at least one of a laser-assisted sintering device, a testing and sorting machine, a dicing machine, and a screen printing machine.
