Description

TECHNICAL FIELD

[0001] The utility model relates to the field of electronic device, in particular to a kind of transport system for transporting panel. BACKGROUND

[0002] With the vigorous development of electronic device, people's demand for circuit board is more and more large.And in the product function of the component carrier equipped with one or more electronic components is growing and the gradual miniaturization of such components and the number of components to be installed on the component carrier, such as printed circuit board, is increasing, the requirement for the integrity and precision of circuit board structure is higher and higher.

[0003] In the prior art, in the manufacturing process of circuit board, the circuit board needs to be transported to each processing station, and processed at each processing station.In order to ensure the integrity and precision of circuit board structure, avoid the damage of accidental scratch or extrusion in the transportation process to the circuit board structure, and avoid the pollution of foreign matter attached to the surface of circuit board to the circuit on the circuit board, usually a board is placed on one main surface of the circuit board, and a protective film is placed on the other opposite main surface of the circuit board, to support and protect the circuit board, so that the circuit board will not be scratched and damaged in the transportation process.

[0004] However, because the electronic board needs to remove the board and / or protective film set on the surface before processing, the circuit board is divided into multiple subparts and placed in the transport car in a stacked manner, and then transported to another processing station, but in the prior art, these operations are all manually performed, not only time-consuming and laborious, but also very likely to cause damage to the surface of the electronic board during manual operation, resulting in the reduction of product yield.

[0005] Therefore, a safe and reliable and automated system for processing and transporting circuit board is needed. UTILITY MODEL CONTENT

[0006] The purpose of the utility model includes providing a transport system for transporting panel, to at least solve the defects described above about prior art.

[0007] According to the exemplary embodiment of the utility model, a kind of transport system for transporting panel, panel can be divided into multiple sub-panels, sub-panels can be configured as component carrier or multiple component carriers to be individualized, panel can be covered by protective film, transport system can include: first processing area, first processing area can accommodate panel and the back plate and holding plate of keeping panel, wherein, back plate can be located above holding plate, and panel and back plate can be fixed by fixing device arranged on holding plate;Lifting unit, lifting unit can be located below first processing area, and be configured to make panel disengage from fixing device;Movable pick-up unit, pick-up unit can be configured to remove protective film from panel, then pick-up can be lifted by the panel disengaged by unit and transport panel to second processing area.

[0008] In the context of the present application, the term "panel" can be divided into multiple parts, which can be referred to as sub-panels, which can be configured as component carriers or multiple component carriers to be individualized. Typically, the panel is subjected to a fishing process before being fed into the transport system of the present application, in which the panel is mechanically cut into multiple sub-panels. The multiple "sub-panels" cut after the preliminary processing, such as mechanical cutting, do not disengage from the fixing device, but are still arranged in a flat manner on the back plate and holding plate for support, thereby forming a "panel" on the back plate for easy transportation. Preferably, during or after the preliminary processing, a protective film can also be provided on the multiple "sub-panels" to prevent dust and foreign matter generated during production from adhering to the surface of the panel or sub-panels, affecting product quality. When further processing is required, the larger area panel can be re-divided into multiple sub-panels by the transport system of the present application, preferably the multiple sub-panels are split to form a stack of stacked components. Then, the stack of multiple sub-panels is transported by manual or automatic transport device to other process flow for further processing.

[0009] The panel transported into the transport system is placed in the first processing area for processing, after the cooperation of the lifting unit and the movable pick-up unit, the original panel can be divided into multiple sub-panels with smaller area, and each sub-panel can be transported and stored in the second processing area by the pick-up device of the movable pick-up unit. In the case where the original panel is divided into multiple sub-panels with smaller area, the second processing area for storing sub-panels can be designed to have an area smaller than the first processing area for storing original panel, so that the design of the entire transport system is more compact and occupies less area.

[0010] In the context of the present application, the term "component carrier" can particularly refer to any support structure capable of hosting one or more components thereon and / or therein to provide mechanical support and / or electrical connections. In other words, the component carrier can be configured as a mechanical and / or electronic carrier of components. In particular, the component carrier can be one of a printed circuit board, an organic interposer and an IC (integrated circuit) substrate. The component carrier can also be a hybrid board combining different carriers of the above-mentioned types of component carriers.

[0011] In the context of the present application, the term "component carrier structure" can particularly denote a preform of presently manufactured component carriers. Specifically, the component carrier structure can comprise a plurality of component carriers or preforms thereof still connected in bulk, which can be manufactured in a batch process before singulation. In particular, the component carrier structure can be a panel (e.g. having dimensions of 18 inch x 24 inch or larger), or an array (e.g. of six component carriers presently manufactured). For example, the manufactured component carriers can be printed circuit boards or IC substrates.

[0012] In an optional implementation, the manufactured component carriers can comprise a stack of at least one electrically insulating layer structure and / or at least one electrically conductive layer structure. For example, the component carrier can be a laminate of electrically insulating layer structures and electrically conductive layer structures, in particular formed by applying mechanical pressure and / or thermal energy. The "stack" can provide a panel-like component carrier capable of providing a large mounting surface for other components and still being very thin and compact. The term "layer structure" can particularly refer to a continuous layer, a patterned layer or a plurality of non-continuous islands in one common plane.

[0013] In the context of the present application, the term "printed circuit board" (PCB) can particularly denote a panel-shaped component carrier formed by laminating several electrically conductive layer structures with several electrically insulating layer structures, e.g. by applying pressure and / or by providing thermal energy. As a preferred material for PCB technology, the electrically conductive layer structures are made of copper, while the electrically insulating layer structures can consist of resin and / or glass fibers, i.e. so-called prepreg or FR4 material. The various electrically conductive layer structures can be connected to each other in a desired manner by forming vias through the laminate, e.g. by laser drilling or mechanical drilling, and by filling them with an electrically conductive material, in particular copper, to form via connections. In addition to one or more components that can be embedded in the printed circuit board, the printed circuit board is typically configured to accommodate one or more components on one or both of the opposing surfaces of the panel-shaped printed circuit board. They can be connected to the respective main surface by soldering. The dielectric part of the PCB can consist of resin and reinforcing fibers, such as glass fibers.

[0014] In the context of the present application, the term "substrate" can in particular denote a component carrier. In terms of a PCB, the substrate can be a relatively small component carrier, on which one or more elements can be mounted, and can act as a connection medium between one or more chips and another PCB. For example, the substrate can have substantially the same dimensions as the components (in particular electronic components) to be mounted thereon (for example in the case of chip scale packaging (CSP)). More specifically, the substrate can be understood as a carrier for electrical connections or electrical networks, and as a component carrier comparable to a printed circuit board (PCB), but with a comparably high lateral and / or vertical arrangement connection density. For example, lateral connections are electrically conductive channels, while vertical connections can be vias. These lateral and / or vertical connections are arranged within the substrate and can be used to provide electrical, thermal and / or mechanical connections between packaged components or non-packaged components (such as bare dies), in particular IC chips, and a printed circuit board or an intermediate printed circuit board. Thus, the term "substrate" also includes "IC substrates". The dielectric part of the substrate can consist of a resin with reinforcing particles (for example reinforcing spheres, in particular glass spheres).

[0015] The substrate or interposer can comprise or consist of at least one layer of glass, silicon (Si) or a photoimageable or dry-etchable organic material such as an epoxy-based build-up material (for example an epoxy-based build-up film) or a polymeric compound such as a polyimide, a polybenzoxazole or a benzocyclobutene functionalized polymer.

[0016] In an alternative embodiment, the at least one electrically insulating layer structure can comprise at least one of the following: a resin (for example a reinforced or non-reinforced resin, for example an epoxy resin or a bismaleimide-triazine resin), a cyanate ester resin, a polybenzene derivative, a glass (in particular glass fibers, multilayer glass, glass-like materials), a prepreg (for example FR-4 or FR-5), a polyimide, a polyamide, a liquid crystal polymer (LCP), an epoxy-based build-up film, a polytetrafluoroethylene (PTFE, Teflon), a ceramic, a metal oxide. Reinforcing structures such as fiber webs, fibers or spheres can also be used, for example made of glass (multilayer glass). While prepregs, in particular FR4, are generally preferred for rigid PCBs, other materials, in particular epoxy-based build-up films or photoimageable dielectric materials, can also be used. For high-frequency applications, high-frequency materials such as polytetrafluoroethylene, liquid crystal polymers and / or cyanate ester resins, low-temperature co-fired ceramics (LTCC) or other low, very low or ultra-low DK materials can be implemented in the component carrier as electrically insulating layer structures.

[0017] In the context of the present application, the term "back plate" can particularly mean a plate member that is in direct contact with the panel and supports the panel. In addition, the term "holding plate" can particularly mean a plate member for bearing and supporting both the back plate and the panel, which can also be commonly referred to as a spacer plate in the art. Generally, one major surface of the back plate is in contact with the panel and the other major surface is in contact with the spacer plate, and thus the back plate is generally smooth and made of a flexible material to avoid damage to the panel on the back plate. In contrast, the holding plate has one major surface in contact with the back plate and the other major surface in contact with external devices such as a transport belt, a wall of a transport container, or a clamping member, and thus the holding plate is generally made of a relatively hard material to maintain the support effect while avoiding damage to the panel during transportation.

[0018] In the context of the present application, the terms "longitudinally", "longitudinal direction" can particularly mean the transport direction of the transport system or a direction parallel to the transport direction, the terms "laterally", "lateral direction" can particularly mean a direction perpendicular to the transport direction of the transport system and parallel to the ground on which the transport system is installed, and the terms "vertically", "vertical direction" can particularly mean a direction perpendicular or approximately perpendicular to the ground on which the transport system is installed.

[0019] Other exemplary embodiments of the transport system for transporting the panel will be described below.

[0020] In an optional embodiment, the pickup unit can be configured to form a negative pressure inside the pickup unit when contacting the surface of the protective film or panel to be picked up, so as to firmly adsorb the surface of the picked-up protective film or panel.

[0021] In an optional embodiment, the pickup unit can include a plurality of first pickup devices configured to pick up a sub-panel of the panel and transport the sub-panel to the second processing area.

[0022] In an optional embodiment, the pickup unit can include a plurality of second pickup devices configured to place a spacer on the sub-panel when the sub-panel is transported to the second processing area. The first pickup devices and the second pickup devices can operate simultaneously, i.e., while the first pickup devices pick up a sub-panel of the panel and transport the sub-panel to the second processing area, the second pickup devices have already picked up spacers and are waiting to place the spacers on the panel in the second processing area, which can make the transport system operate at a higher efficiency.

[0023] In optional embodiments, the sub-panels and the spacers can be placed alternately in a stack such that each two adjacent sub-panels are separated by a spacer. The spacers can also prevent damage to the panels, such as circuit board structures, from accidental scratches or pressure during transportation, and prevent contamination of the circuit board lines from foreign objects attached to the surface of the panels, such as circuit boards.

[0024] In optional embodiments, the transportation system can include a cart configured to transport the sub-panels from the second processing area to other processing procedures.

[0025] In optional embodiments, the plurality of first pick-up devices can be divided into groups, each group of the first pick-up devices being controlled by an independent driving mechanism to move independently of one another.

[0026] In optional embodiments, the groups of first pick-up devices are controlled by respective driving mechanisms to move to different heights. Independent movement of the groups of first pick-up devices in horizontal and vertical directions can enhance flexibility in the picking process.

[0027] In optional embodiments, the first pick-up devices include a plurality of suction cups configured to pick up the protective film or the sub-panels by vacuum suction.

[0028] In optional embodiments, one of the plurality of suction cups is placed at a central region of the sub-panels, and the other suction cups are placed around the edges of the sub-panels.

[0029] In optional embodiments, the suction cups placed around the edges of the sub-panels are placed at respective corners of the sub-panels. Such an arrangement can ensure picking efficiency while avoiding undesirable effects on the central line-dense regions of the panels.

[0030] In optional embodiments, the second pick-up device can include an automated robotic arm.

[0031] In optional embodiments, the pick-up unit can further be provided with an identification device configured to identify whether the pick-up unit picks up a protective film or a panel, and whether the picked up is a protective film or a panel.

[0032] In optional embodiments, the transportation system can further include a controller for storing product information, the controller being configured to perform one or more of the following: (a) determine movement of the pick-up unit; (b) determine placement of the pick-up unit based on distribution and size of the panels; and (c) define a specific suction pattern as central suction and / or corner suction.

[0033] In an optional embodiment, the fixing device can include at least one pin that can be inserted into a hole provided on the panel and the back plate, ensuring that the panel remains fixed when being transported.

[0034] In an optional embodiment, the removed protective film can be placed into a collection unit by the picking unit.

[0035] In an optional embodiment, the protective film can further be provided with a weight member covering the protective film, which can increase the weight of the protective film when the protective film is peeled. Generally, the weight of a panel containing metal (e.g., copper) is greater than that of the protective film. By increasing the weight of the protective film with the weight member, the negative pressure parameter in the picking device can be adjusted without affecting the efficient picking of the protective film or the panel.

[0036] In an optional embodiment, the weight member can be a plastic frame.

[0037] In an optional embodiment, the first processing area is larger in area than the second processing area.

[0038] According to the embodiments of the utility model, the transport system for transporting the panel includes: a first processing area, the first processing area contains a panel, a back plate and a holding plate for holding the panel, wherein the back plate is located above the holding plate, and the panel and the back plate are fixed by a fixing device provided on the holding plate; a lifting unit, the lifting unit is below the first processing area and is configured to detach the panel from the fixing device; a movable picking unit, the picking unit is configured to remove a protective film from the panel, then pick up the panel detached by the lifting unit and transport the panel to a second processing area, and the first processing area is larger in area than the second processing area.

[0039] The transport system adopts a new lifting unit for releasing the panel from the fixing device, a high-precision identification device such as a sensor for identifying the picked object, a movable picking unit, and other structures, so that the panel can be automatically divided into multiple sub-panels, reducing the risk of scratching and damaging the panel during separation and transportation. Such automatic separation and transportation is safe, reliable and time-saving, greatly improving production capacity. Moreover, the back plate, the holding plate and the spacer for supporting the panel and other devices are reusable. BRIEF DESCRIPTION OF DRAWINGS

In order to avoid unnecessary repetition, elements or features already elucidated with respect to the foregoing embodiments are not elucidated again at the location of the following description.

[0055] Furthermore, spatially relative terms, such as "front" and "back", "upper" and "lower", "left" and "right", and the like, can be used herein for describing the orientation of one element or features to another element or features as illustrated in the figures. Such spatially relative terms can apply to the orientations of the devices in use different from the orientation depicted in the figures. Obviously, all such spatially relative terms refer to the orientation shown in the figures for ease of description and are not necessarily limiting as the devices according to embodiments of the present application can assume different orientations in use than the orientation illustrated in the figures. Furthermore, the terms "first", "second", "third", etc. are used herein for description purposes only and do not imply or suggest relative importance.

[0056] In the description of the present application, it should be noted that unless specifically defined and limited otherwise, the terms "mounting", "connected", "connection" should be interpreted broadly, for example, can be fixedly connected, can be detachably connected, or integrally connected; can be mechanically connected, can be electrically connected; can be directly connected, can be indirectly connected through an intermediate medium, can be internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0057] Figure 1 A transport system 1 for transporting a panel according to embodiments of the present application is schematically shown. The panel 10 can be divided into a plurality of sub-panels 10', which can be configured as a component carrier or a plurality of component carriers to be individualized.

[0058] The transport system 1 according to embodiments of the present application can comprise a first processing area 2, a lifting unit 3, and a movable picking unit 5.

[0059] The first processing area 2 can accommodate the panel 10 and the back plate 12 and the holding plate 14 holding the panel 10, wherein the back plate 12 can be located above the holding plate 14, and the panel 10 and the back plate 12 can be fixed by the fixing device 7 provided on the holding plate 14.

[0060] The lifting unit 3 can be below the first processing area 2, and the lifting unit 3 can be configured to disengage the panel 10 from the fixing device 7.

[0061] The movable picking unit 5 can be configured to remove the protective film 16 from the panel 10, and then pick up the panel 10 disengaged by the lifting unit 3 and transport the panel 10 to the second processing area 4, and the first processing area 2 can be larger than the area of the second processing area 4.

[0062] In the context of the present application, the longitudinal direction can particularly represent the transport direction of the transport system or a direction parallel to the transport direction, the transverse direction can particularly represent a direction perpendicular to the transport direction of the transport system, and the vertical direction can particularly represent a direction perpendicular or approximately perpendicular to the ground on which the transport system is installed.

[0063] In some embodiments, as schematically shown in Figures 2 to 4 , the panel 10 to be processed is generally supported by the back plate 12 and the holding plate 14. Specifically, one major surface of the back plate 12 is in contact with the panel 10 and the other major surface is in contact with the holding plate 14, so the back plate 12 is generally smooth and made of a flexible material to avoid damage to the panel 10 on the back plate 12. In contrast, the holding plate 14 has one major surface in contact with the back plate 12 and the other major surface generally in contact with external devices such as a transport belt, a wall of a transport container or a clamping member, etc., so the holding plate 14 is generally made of a relatively hard material to maintain the support effect while avoiding damage to the panel 10 during transport. The back plate 12 and the holding plate 14 can be made of different materials or the same material, for example, the back plate 12 and the holding plate 14 can both be made of plastic.

[0064] As shown in Figure 2 , the panel 10 made on the back plate 12 can include 12 sub-panels 10' to be separated. The number of sub-panels 10' is only illustrative, and different holding plates 14 can have panels 10 including more sub-panels 10' placed thereon.

[0065] As shown in Figures 3a to 3c and Figure 4As shown in the figures, a plurality of first holes 102 can be provided on the panel 10, a plurality of second holes 122 can be provided on the back plate 12, a plurality of third holes 142 can be provided on the holding plate 14, and a fixing device 7 can be provided on the main surface of the holding plate 14 which is in contact with the back plate 12. The fixing device 7 can be configured to pass through the second holes 122 of the back plate 12 and the first holes 102 of the panel 10 when the panel 10 and the back plate 12 are placed on the holding plate 14, thereby firmly fixing the panel 10 and the back plate 12 on the surface of the holding plate 14, ensuring the stability during mechanical cutting and transportation. It can be understood by those skilled in the art that the first holes 102 of the panel 10, the second holes 122 of the back plate 12 and the fixing device 7 provided on the holding plate 14 are aligned in the vertical stacking direction, so that the first holes 102 and the second holes 122 can be inserted through the fixing device 7, the panel 10 and the back plate 12 are fixed flat on the holding plate 14, and the panel 10 will not be warped. In addition, the third holes 142 of the holding plate 14 are aligned with the columnar members 34 on the lifting platform 32 in the vertical direction, so that during the lifting process, the columnar members 34 can smoothly pass through the third holes 142 to contact the back plate 12 and lift the back plate 12 and the panel 10. Furthermore, the first holes 102, the second holes 122 and the third holes 142 are not aligned in the vertical direction to avoid the columnar members 34 being mistakenly inserted into the first holes 102 and / or the second holes 122, affecting the fixation of the panel 10.

[0066] The third holes 142 of the holding plate 14 are configured to allow the columnar members 34 provided on the lifting unit 3 to pass through when the lifting unit 3 approaches the holding plate 14. The specific cooperation between the third holes 142 and the columnar members 34 will be described below.

[0067] In the embodiment shown in Figures 3a to 3c and Figure 4 In the embodiment shown, the fixing device 7 includes eight pins, the panel 10 is provided with eight first holes 102 and the back plate 12 is provided with eight second holes 122, and the positions of the pins correspond one-to-one to the positions of the first holes 102 and the second holes 122.

[0068] It can be understood that the number and position of the pins, the first holes 102 and the second holes 122 shown here are only illustrative and can be changed according to the size of the panel 10 and specific operation requirements. For example, there can be 4, 5, 6, 7, 9, 10, 20, etc. pins, first holes 102 and second holes 122, and the pins, first holes 102 and second holes 122 can be not only provided around the peripheral portion of the plate, but also at least partially provided in the central region of the plate when the panel area is large. The specific number and arrangement position are adjusted according to the requirements to ensure that the panel 10 will not be warped during handling due to too few or too many pins.

[0069] In addition, the number of the first holes 102 and the second holes 122 can be set to be different from the number of the pins, so that a greater variety of holding plates 14 can be allowed to be used.

[0070] In some embodiments, the diameter of the pins of the fixing device 7 and the hole diameter of the first holes 102 and the second holes 122 can be set in the range of 1mm-7mm, for example, can be set to 2mm, 3mm, 4mm, 5mm, 6mm.

[0071] In some embodiments, the pins of the fixing device 7 and the first holes 102 and the second holes 122 through which the pins pass have a gap in the radial direction, avoiding cracks on the panel 10 due to interference fit of the pins with the first holes 102 and the second holes 122. Preferably, the gap can be 50μm.

[0072] In some embodiments, the panel 10 to be processed can also be covered by a protective film 16.

[0073] In some embodiments, in addition to being provided with the protective film 16, the panel 10 can also be provided with a weight 18 covering the protective film 16. The weight 18 can increase the weight of the protective film 16 when the protective film 16 is peeled off, so that the protective film 16 is slightly weighted to ensure that the protective film 16 can be stably placed into the collection unit 6 for reuse after being removed, without falling out of the collection unit 6 to cause waste. In addition, generally, the weight of the panel 10 containing metal (for example, copper) is greater than that of the protective film 16, and after increasing the weight of the protective film 16 by the weight 18, the parameters in the picking device 5 do not need to be adjusted, and the protective film 16 or the panel 10 can be efficiently picked up. In some embodiments, the weight 18 can be a plastic frame or a foam board.

[0074] In some embodiments, the collection unit 6 can be placed beside the first processing area, for example, in the transverse direction shown beside the first processing area, or can also be placed in other areas that are convenient for operation. For example, the collection unit 6 can be a collection basket. Figure 1

[0075] In some embodiments, the lifting unit 3 can include at least one lifting platform 32 and at least one columnar piece 34 provided on each lifting platform 32. Referring to the schematic view of the lifting unit 3 shown in Figure 6 The lifting unit 3 includes four lifting platforms 32, and each lifting platform 32 is provided with four columnar pieces 34. It can be understood that the number of the lifting platforms 32 and the columnar pieces 34 thereof here is only illustrative, and more or fewer lifting platforms 32 and columnar pieces 34 can be selected by those skilled in the art according to specific operation requirements.

[0076] ​For example, three, five, six or more posts 34 can be selected to be provided on each of the lifting platforms 32. In some embodiments, the diameter of the posts 34 can be 10 mm, or can be set to other diameters according to the requirements of the plate processing, for example, can be set to 8 mm, 9 mm, 11 mm, or 12 mm. Preferably, the diameter of the posts 34 on the lifting platform 32 can be greater than or equal to the diameter of the pins of the fixing device 7.

[0077] It can be noted that the number of posts 34 is consistent with the number of third holes 142 provided in the holding plate 14, so that when the lifting platform 32 moves upward in the vertical direction to approach the holding plate 14, the posts 34 can pass through the third holes 142 in the holding plate 14, and as the lifting platform 32 continues to move, the tips of the posts 34 contact the surface of the back plate 12 and lift the back plate 12 and the faceplate 10 upward, so that the back plate 12 and the faceplate 10 are separated from the holding plate 14. After separation, the back plate 12 and the faceplate 10 are converted from being supported by the holding plate 14 to being supported and lifted by the posts 34, so as to be picked up by the pick-up unit 5 located above the faceplate 10.

[0078] In some embodiments, the distance that the tips of the posts 34 continue to move upward after contacting the surface of the back plate 12 should be greater than or equal to the length of the pins of the fixing device 7. That is, the length of the posts 34 should be greater than the length of the pins of the fixing device 7. In particular, considering that the posts 34 are used to lift the back plate 12 and the faceplate 10 by passing through the third holes 142 in the holding plate 14, the length of the posts 34 should be greater than or equal to the sum of the thickness of the holding plate 14 and the length of the fixing device 7. For example, in the case where the length of the pins of the fixing device 7 is 1 cm, the tips of the posts 34 on the lifting platform 32 should move at least 1 cm upward in the vertical direction after contacting the lower surface of the back plate 12 through the third holes 142, so that the faceplate 10 and the back plate 12 can be separated from the fixing device 7, and the thickness of the holding plate 14 is not specifically limited here. However, it can be understood by those skilled in the art that the length of the posts 34 can be specifically set according to the thickness of different holding plates 14 and the length of the fixing device 7.

[0079] It can be understood that the number of third holes 142 should be greater than or equal to the number of columnar pieces 34 to ensure that all columnar pieces 34 can successfully pass through the retaining plate 14 as the lifting platform 32 rises, thereby contacting the back plate 12 and eventually lifting the back plate 12 and the face plate 10, so that the face plate 10 can be separated from the pin of the fixing device 7. If the number of third holes 142 is less than the number of columnar pieces 34, then part of the columnar pieces 34 will abut against the lower surface of the retaining plate 14 but cannot pass through the retaining plate 14 as the lifting unit 3 rises, in which case the retaining plate 14 will also be lifted up by the upward moving columnar pieces 34, causing the face plate 10 and the back plate 12 to be unable to separate from the retaining plate 14, and in severe cases, the retaining plate 14 can be tilted, causing the face plate 10 and the back plate 12 to become tilted and even warped, or to slide off the tilted retaining plate 14, which adversely affects the product yield.

[0080] In some embodiments, the picking unit 5 can include a plurality of first picking devices 52 and a plurality of second picking devices 54. The first picking devices 52 can be configured to pick the sub-panels 10' of the face plate 10 and transport the sub-panels 10' to the second processing area 4. The second picking devices 54 can be configured to place spacers 19 on the sub-panels as the sub-panels are transported to the second processing area. In the second processing area 4, the sub-panels 10' and the spacers 19 can be placed alternately in a stack such that every two adjacent sub-panels 10' are separated by a spacer, avoiding friction between adjacent sub-panels 10' that can damage the surface of the sub-panels 10'.

[0081] In some embodiments, the spacers 19 can be plastic inserts. Preferably, the surface area of the spacers 19 is greater than the surface area of the sub-panels 10' to completely surround the sub-panels 10', avoiding collision or friction with external structures or adjacent sub-panels 10', achieving good protection to facilitate the transportation of the sub-panels 10' to other processing processes.

[0082] In preferred embodiments, the first picking devices 52 and the second picking devices 54 can be automated mechanical arms.

[0083] The picking unit 5 according to the embodiments of the present application can be configured to form a negative pressure inside the picking unit 5 when contacting the surface of the protective film 16 or the face plate 10 to be picked up, so as to firmly adsorb the surface of the picked protective film 16 or face plate 10.

[0084] In some embodiments, the plurality of first picking devices 52 can be divided into a plurality of groups of first picking devices 52, each group of first picking devices 52 being controlled by an independent driving mechanism to move independently of each other. In some embodiments, the plurality of groups of first picking devices 52 can be controlled by respective driving mechanisms to move to different heights.

[0085] In some embodiments, the first picking device 52 can include a plurality of first suction cups 522 configured to pick up the protective film 16 or the sub-panel 10’ by vacuum suction. One of the plurality of first suction cups 522 is placed at the central region of the sub-panel 10’, and the other of the plurality of first suction cups 522 is placed around the edge of the sub-panel 10’. Preferably, the first suction cups 522 placed around the edge of the sub-panel 10’ can be placed at the respective corners of the sub-panel 10’.

[0086] The operation of the first picking device 52 will now be described in conjunction with the embodiments shown in Figure 5 , Figures 8 to 10 It can be seen that in the present embodiment, the plurality of first picking devices 52 can be grouped in groups of three first picking devices 52. Each group of first picking devices 52 can be driven by a separate motor, for example, the three first picking devices 52 can be driven by a motor to move synchronously in the longitudinal direction, the transverse direction, or the vertical direction.

[0087] It can be understood that the specific grouping of the first picking devices 52 can be determined according to the arrangement of the panel 10. For example, in the embodiment shown in Figure 10 , the panel 10 is arranged with 6 columns of sub-panels 10’ in the transverse direction, in which case, the three first picking devices 52 of the group can pick up six sub-panels 10’ in the same row twice, which is much more efficient than manually separating the sub-panels 10’ one by one. Of course, if the space of the processing area is limited, two first picking devices 52 can also be grouped together and controlled by a separate motor.

[0088] Each first picking device 52 can include six first suction cups 522. The six first suction cups 522 can be suctioned around the edge of each sub-panel 10’ (as shown in Figure 5 It can be understood that the number and specific arrangement of the first suction cups 522 can be adjusted. For example, in the case of a larger area of the sub-panel 10’, more first suction cups 522 can be provided, for example, 7, 8, 9, or more first suction cups 522. The arrangement of the first suction cups 522 can be changed according to the size of the sub-panel 10’, for example, all the first suction cups 522 can be arranged equidistantly around the edge of the sub-panel 10’, the first suction cups 522 can be arranged at the respective corners of the sub-panel 10’, or at least one first suction cup 522 can be arranged at the central region of the sub-panel 10’ and the remaining first suction cups 522 can be arranged equidistantly around the edge of the sub-panel 10’.

[0089] When the panel 10 is lifted by the lifting unit 3 to be separated from the fixing device 7, the three first pickup devices 52 are driven by the driving motor to move above the corresponding three sub-panels 10', move downward in the vertical direction to be close to the upper surface of the sub-panels 10'. When the first suction cups 522 adsorb the sub-panels 10', the first pickup devices 52 are driven by the driving mechanism to move upward in the vertical direction, then move horizontally, preferably in the transverse direction, to the second processing area 4, stop the horizontal movement after reaching the designated position of the second processing area 4, move downward in the vertical direction, and the first suction cups 522 are in the non-vacuum state to place the sub-panels 10' in the second processing area.

[0090] Now the operation of the second pickup device 54 will be described in combination with the embodiment shown in Figure 8 and Figure 11 It can be seen that in the present embodiment, the plurality of second pickup devices 54 can be grouped in groups of three second pickup devices 54. Each group of second pickup devices 54 can be driven by a separate motor, for example, three second pickup devices 54 can be driven by a motor to move synchronously in the longitudinal direction, transverse direction or vertical direction.

[0091] Considering that in the second processing area, the sub-panels 10' and the spacers 19 are stacked in an alternating manner, it is preferred that the grouping and spacing distance of the plurality of first pickup devices 52 and the plurality of second pickup devices 54 are consistent, and the placement of the sub-panels 10' and the spacing of the spacers 19 can be synchronized. For example, in the present embodiment, the plurality of first pickup devices 52 are grouped in groups of three, and it is preferred that the three second pickup devices 54 are also grouped in groups of three. In this way, when three sub-panels 10' are placed in the second processing area, another three second pickup devices 54 with the same grouping and spacing distance as the first pickup devices 52 can subsequently accurately place three spacers 19 on the three sub-panels 10', finally forming three aligned stacks.

[0092] Similarly, each second pickup device 54 can also include six second suction cups 542. The six second suction cups 542 can be suctioned around the edge of each spacer 19. It can be understood that the number and specific arrangement position of the second suction cups 542 can be adjusted. For example, in the case of a larger area spacer 19, more second suction cups 542 can be provided, such as 7, 8, 9 or more second suction cups 542. The arrangement position of the second suction cups 542 can be changed according to the size of the spacer 19, all second suction cups 542 can be arranged equidistantly around the edge of the spacer 19, the second suction cups 542 can be arranged at each corner of the spacer 19 respectively, or at least one second suction cup 542 is arranged at the central region of the spacer 19 and the remaining second suction cups 542 are arranged equidistantly around the edge of the spacer 19.

[0093] When the three sub-panels 10' are placed in the second processing area 4, the second pickup device 54 is driven by the driving motor to move above the corresponding three spacers 19, and moves downward in the vertical direction to approach the upper surface of the spacer 19. When the second suction cup 542 suctions the spacer 19, the second pickup device 54 is driven by the driving mechanism to move upward in the vertical direction, and then moves horizontally, preferably in the transverse direction, to the second processing area 4, and after reaching above the three sub-panels 10' of the second processing area 4, moves downward in the vertical direction, and the second suction cup 542 releases the negative pressure state to place the spacer 19 on the sub-panels 10' of the second processing area.

[0094] In some embodiments, the above-mentioned driving mechanism for driving the first pickup device 52 and the second pickup device 54 of the pickup unit 5 can adopt a driving motor commonly used in the market. For example, a motor of hydraulic drive, pneumatic drive, electrical drive or mechanical drive type can be used according to the configuration requirements of the production line, site restrictions and other requirements.

[0095] Considering that the pickup unit 5 in the present application picks up electronic devices which are light in weight and delicate in structure, it is preferred to use an electrical drive motor or a pneumatic drive motor. For the electrical drive motor, the power supply is convenient, the response is fast, the driving force is large, the signal detection, transmission and processing are convenient, and flexible control can be achieved. Because the motor speed is high, a speed reduction mechanism (such as harmonic drive, RV cycloid pin wheel transmission, gear transmission, screw transmission and multi-link mechanism, etc.) is usually used, or a large torque, low speed motor without speed reduction mechanism (DD) can be used for direct drive, which can simplify the mechanism and improve the control accuracy. For the pneumatic drive motor, it is usually composed of a cylinder, a valve, a tank and an air compressor, and its characteristics are convenient gas source, rapid action, simple structure, low cost and convenient maintenance.

[0096] In some embodiments, the picking unit 5 can also be provided with an identification device 56, such as a sensor, which can be configured to identify whether the picking unit 5 picks up a protective film 16 or a panel 10 and the kind of the picked object. In other words, the identification device 56 can be configured to identify whether the picking unit 5 picks up an article and, in the case of identifying an article, determine whether the article is a protective film 16 or a panel 10 or other article. For example, the identification device 56 can be a light-sensitive sensor, and different optical coating patterns can be provided on the panel 10 and the protective film 16, and the light-sensitive sensor can sense the optical coating pattern on the article to determine whether the picked object is a sub-panel 10' of the panel 10 or a protective film 16. In the case of picking up a protective film 16, the picking unit 5 will transport the protective film 16 to the collecting unit 6; and in the case of picking up a sub-panel 10', the picking unit 5 will transport the sub-panel 10' to the second processing area 4.

[0097] In some embodiments, the transport system 1 can also include other types of sensors, such as laser sensors, displacement sensors, pressure sensors, etc. In optional embodiments, the transport system 1 can also include a controller for storing and processing product information, which is configured to perform one or more of the following: (a) determine the movement of the picking unit 5; (b) determine the placement position of the picking unit 5 based on the distribution and size of the panel 10; and (c) define a specific suction mode as central suction and / or corner suction, for example, define whether to place the suction head in a central position or a corner position to perform the suction action.

[0098] In some embodiments, a stop device 22 can be provided in the first processing area 2. The stop device 22 can be provided at one end of the first processing area along the transport direction. The stop device 22 is configured to stop the holding plate 14 carrying the panel 10 when the holding plate 14 is transported to a specified position in the first processing area, so that the holding plate 14 stops in the first processing area 2. In some embodiments, as shown in Figure 5 The stop device 22 can be a mechanical stop device or an electrical stop device, for example, the stop device 22 can be a protrusion on a support adjacent to the transport belt. The holding plate 14 carrying the panel 10 is transported by a transport device, such as a conveyor belt or a conveyor roller, into the first processing area, and when the holding plate 14 touches the stop device 22, the transport device stops moving and remains stationary in the first processing area to facilitate the operation of the panel 10 by other units.

[0099] The transport system can include a cart, which can be configured to transport the stacked sub-panels from the second processing area to other processing processes.

[0100] In summary, the operation principle of the transportation system for transporting the faceplate provided by the embodiment of the utility model is as follows: the faceplate 10 and the backplate 12 fixed on the holding plate 14 by the fixing device 7 on the holding plate 14 are transported to the first processing area 2 by the conveying device such as the conveying belt or the conveying roller, when the holding plate 14 contacts the stop device 22, it indicates that the designated processing position is reached, and the processing operation on the faceplate 10 can be started. Optionally, in order to facilitate the stability of the subsequent operation, the system can clamp the edge part of the holding plate 14 by the additional clamping device such as the clamp. First, the lifting unit 3 moves vertically upward, each lifting platform 32 corresponds to a part of the area of the faceplate 10, the columnar piece 34 passes through the third hole 142 in the holding plate 14 and contacts the backplate 12. At this time, the holding plate 14 remains stationary in the first processing area 2, as the lifting unit 3 continues to move vertically upward, the columnar piece 34 passing through the third hole 142 lifts the backplate 12 and the faceplate 10 together, and then remains stationary after the backplate 12 and the faceplate 10 completely separate from the pin of the fixing device 7.

[0101] When the faceplate 10 is lifted by the lifting unit 3 to separate from the fixing device 7, the three first pickup devices 52 are driven by the driving motor to move above the corresponding three sub faceplates 10', move downward in the vertical direction to approach the upper surface of the sub faceplate 10'. In the case that the protective film 16 and / or the weight piece 18 are arranged on the faceplate 10, the first suction disc 522 first adsorbs the protective film 16 and / or the weight piece 18, the first pickup device 52 is driven by the driving mechanism to move upward in the vertical direction, and then moves horizontally, preferably moves horizontally in the transverse direction to above the collecting unit 6, and the first suction disc 522 releases the negative pressure state to put the adsorbed protective film 16 and / or the weight piece 18 into the collecting unit 6.

[0102] After the protective film 16 and / or the weight piece 18 on the surface of the faceplate 10 is completely removed, the first pickup device 52 starts to pick up the faceplate 10. Specifically, the three first pickup devices 52 are driven by the driving motor to move above the corresponding three sub faceplates 10', move downward in the vertical direction to approach the upper surface of the sub faceplate 10'. When the first suction disc 522 adsorbs the sub faceplate 10', the first pickup device 52 is driven by the driving mechanism to move upward in the vertical direction, and then moves horizontally, preferably moves horizontally in the transverse direction to the second processing area 4, stops horizontal movement after reaching the designated position of the second processing area 4, moves downward in the vertical direction, and the first suction disc 522 releases the negative pressure state to put the sub faceplate 10' into the second processing area.

[0103] After the three first pickup devices 52 place the three sub-panels 10', the three second pickup devices 54 then pick up the three spacers 19 and place them on the three sub-panels 10' respectively. Specifically, after the three sub-panels 10' are placed in the second processing area 4, the second pickup device 54 is driven by a drive motor to move above the corresponding three spacers 19, and moves downward in the vertical direction to approach the upper surface of the spacers 19. After the second suction cup 542 adsorbs the spacers 19, the second pickup device 54 is driven by a drive mechanism to move upward in the vertical direction, and then moves horizontally, preferably horizontally in the transverse direction, to the second processing area 4. After reaching above the three sub-panels 10' in the second processing area 4, it moves downward in the vertical direction, and the second suction cup 542 releases the negative pressure state to place the spacers 19 on the sub-panels 10' of the second processing area.

[0104] In some embodiments, the spacer 19 can be placed in a position that facilitates pickup by the pickup unit 5, for example, Figure 1 and Figure 11 As shown, the spacers 19 can be stored near the second processing area 4, for example, placed in a collection tray along one side of the second processing area 4 in a lateral direction. Preferably, the arrangement of the spacers 19 in the collection tray is consistent with the arrangement of the sub-panels 10' in the second processing area 4 (e.g., layout and spacing) so that the second pickup device 54 can efficiently pick up and place them. For example, as schematically shown in the figure, with three first pickup devices 52 and three second pickup devices 54, three sets of spacers 19 can be placed in the collection tray accordingly, and the distance between adjacent sets of spacers 19, the distance between adjacent first pickup devices 52, and the distance between adjacent second pickup devices 54 can be set to be the same. In this way, the three spacers 19 picked up and placed into the second processing area 4 by the second pickup device 54 each time can be conveniently placed onto the three sub-panels 10' placed into the second processing area 4 by the first pickup device 52 each time. It is understood that the number and arrangement of the spacers 19 described herein are merely illustrative and can be rearranged according to changes in the first pickup device 52 and the second pickup device 54.

[0105] Subsequently, the first picking device 52 and the second picking device 54 repeat the picking operation on the sub-panels 10' and the spacers 19 until all the sub-panels 10' on one panel 10 are picked, and all the sub-panels 10' are placed in the second processing area 4 to form a stack with the spacers 19, and then are transported to a subsequent processing process. After the picking is completed, the first picking device 52 and the second picking device 54 are restored to the original position and remain stationary. Since there is no panel 10 on the surface of the back plate 12, the lifting unit 3 is thus moved downward in the vertical direction, and the back plate 12 falls back onto the holding plate 14 with the movement of the lifting unit 3, and the back plate 12 is in contact with the holding plate 14 and is fixed by the fixing device 7 on the holding plate 14 as the columnar member 34 is completely separated from the third hole 142 of the holding plate 14. The clamping device in the first processing area releases the clamping on the holding plate 14, and the holding plate 14 and the back plate 12 are thus continuously transported by the conveying belt to, for example, another collection frame for subsequent reuse. After a new panel 10 is transported to the conveying system 1, the above-mentioned automatic separation and transportation process is repeated.

[0106] In addition, it can be understood that the above-mentioned transportation direction is only illustrative, and can be changed according to the production layout, as long as the automatic separation and automatic transportation are realized through the cooperation of the lifting unit 3, the picking unit 5, the fixing device 7 and other structures.

[0107] It is easy for those skilled in the art to understand that the above-mentioned operation sequence of the above-mentioned conveying system 1 is not fixed and can be changed according to the change of the structure of each unit in the conveying system 1.

[0108] The conveying system provided by the embodiment of the present application adopts a new lifting unit for releasing the panel from the fixing device, a high-precision recognition device for recognizing the picked object, and a picking unit that can automatically move, so that the panel can be automatically divided into multiple sub-panels, reducing the risk of scratching and damaging the panel during separation and transportation. Such an automatic separation and transportation method is safe, reliable and time-saving, and greatly improves the production capacity. Moreover, the back plate, the holding plate and the spacer and other devices for supporting the panel are reusable.
