Abstract
Description
Technical Field
[0001] This utility model relates to the field of substrate transport technology, and in particular to a mechanism suitable for transporting warped substrates. Background Technology
[0002] In the packaging process, some products undergo a ball-mounting process. After ball mounting, they are cleaned in a cleaning machine and then inspected by an automated optical inspection machine. The transfer of products between these processes is sometimes achieved using a track mechanism. Taking the transport of a substrate from the cleaning machine to the optical inspection machine as an example, a track mechanism typically transports the cleaned substrate to the optical inspection machine for automatic inspection. After inspection, the track mechanism continues to transport the substrate to the next process.
[0003] Existing track mechanisms typically transport substrates via belts, with an upper fixed clamp above the belt. The height between the belt and the upper fixed clamp is generally only 8mm. Under normal circumstances, substrates with a thickness or warpage of less than 8mm can be smoothly clamped and transferred between the belt and the upper fixed clamp. However, once the warpage of the substrate exceeds 8mm (some substrates warp up to 15mm), the warpage height exceeds the height of the upper fixed clamp, preventing the substrate from entering the space between the belt and the clamp, thus leading to the scrapping of the substrate.
[0004] Therefore, it is necessary to provide a mechanism capable of transporting warped substrates to solve the above-mentioned problems. Utility Model Content
[0005] The purpose of this invention is to provide a substrate conveying mechanism capable of conveying warped substrates.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a substrate conveying mechanism is provided, comprising a track assembly, a holding assembly, and a mounting wall; wherein, the track assembly includes at least a conveying track and a first driving member, the conveying track is mounted on one side of the mounting wall, the first driving member is connected to the conveying track and is used to drive the conveying track to move or rotate to convey the substrate; the holding assembly includes at least a holding plate and a second driving member, the holding plate is disposed above the mounting wall, the second driving member is connected to the holding plate and is used to drive the holding plate to rise and fall, so that the holding plate can hold or detach the substrate on the conveying track.
[0007] Preferably, the pressing assembly further includes a connecting plate, and the pressing plate is connected to the second driving member through the connecting plate. The connection plate allows multiple second driving members to drive one pressing plate or one second driving member to drive multiple pressing plates as needed, thereby making the setting of the pressing plate more flexible and the driving more convenient.
[0008] Preferably, the pressing assembly further includes a guide rail and a slider. The guide rail is fixed to the side of the mounting wall opposite to the conveying track and extends vertically. The connecting plate is slidably connected to the guide rail via the slider, thereby stabilizing the lifting and lowering of the connecting plate and the pressing plate and reducing driving effort.
[0009] Preferably, the conveying track is a conveyor belt with a ring structure, and the first driving member drives the conveyor belt to rotate to convey the substrate.
[0010] Preferably, the track assembly further includes a plurality of drive wheels mounted on the side of the mounting wall, the conveyor belt being wound around each of the drive wheels, wherein one of the drive wheels is connected to the first drive member, and the first drive member drives the drive wheel connected thereto to rotate so as to drive the conveyor belt to rotate.
[0011] Preferably, the conveying surface formed by the conveying track is lower than the top surface of the mounting wall. Therefore, the side of the mounting wall can limit the substrate on the conveying track to prevent the substrate from shifting during conveying and causing damage to the packaging and other structures on the substrate. At the same time, it makes the upper part of the conveying track seamless, so that it can be used for bare board conveying of ultra-thin substrates and effectively avoids the board jamming problem in the conveying of ultra-thin substrates in the prior art.
[0012] Preferably, the conveying surface formed by the conveying track is higher than the top surface of the mounting wall; the track assembly further includes a limiting block, which is installed on the top surface of the mounting wall, with its top surface higher than the conveying surface of the conveying track and its bottom surface lower than the conveying surface. The limiting block is used to laterally limit the substrate conveyed on the conveying track, and the lateral direction intersects with the conveying direction of the conveying track. In this application, the limiting block is located on the side of the conveying surface of the conveying track, with its top surface higher than the conveying surface and its bottom surface lower than the conveying surface, thereby forming a seamless planar conveying track, which is suitable for bare board conveying of ultra-thin substrates and effectively avoids the plate jamming problem in the conveying of ultra-thin substrates in the prior art.
[0013] Preferably, the horizontal position of the limiting block is adjustable in the lateral direction, and the adjustment direction of the limiting block intersects with the conveying direction of the conveying track. By adjusting the horizontal position of the limiting block and changing the conveying track of different widths, it is possible to adapt to the conveying of substrates of different sizes.
[0014] Preferably, the substrate conveying mechanism further includes a detection element and a controller. The detection element is installed on at least one of the track assembly, the holding assembly, and the mounting wall, and is used to detect whether the substrate has reached the position of the holding plate. The controller is electrically connected to the detection element and the second driving element, respectively, and is used to control the second driving element to drive the holding plate to move up and down based on the detection result of the detection element. Setting up a detection element to detect the position of the substrate makes the substrate position determination more accurate, thereby driving the holding plate to accurately hold the substrate and avoiding damage to the substrate caused by accidental contact or obstruction.
[0015] Preferably, the detection element is a fiber optic sensor, which simplifies the position detection of the substrate.
[0016] Preferably, the holding component is set at least corresponding to the detection position of the substrate. Therefore, when the substrate reaches the position of the holding plate, the controller controls the second driving member to drive the holding plate to descend in order to hold the substrate. After the substrate detection is completed, the controller controls the second driving member to drive the holding plate to rise in order to detach from the substrate, so that the substrate can be continued to be transported.
[0017] Preferably, the substrate conveying mechanism includes two track assemblies, two holding assemblies, and two mounting walls. The two mounting walls are spaced apart. The conveying tracks of the two track assemblies are respectively located on the inner sides of the two mounting walls and at the same height. The two track assemblies support and convey the opposite sides of the substrate. The holding plates of the two holding assemblies are respectively located above the two mounting walls and are symmetrical. The two holding plates hold the opposite sides of the substrate for detection without affecting the detection of the substrate.
[0018] Compared with existing technologies, the substrate conveying mechanism of this invention features a movable pressing plate in the pressing assembly, with a second driving member to drive the pressing plate to rise and fall. This allows the pressing plate to press against and detach from the substrate on the conveying track. When the substrate is not yet at the pressing plate's position, the pressing plate is in an upward state, ensuring smooth conveying of the warped substrate without jamming. When the substrate reaches the pressing plate's position, the pressing plate descends and presses against the warped substrate, clamping it for inspection or other operations. After inspection or other operations are completed, the pressing plate rises and detaches from the substrate, allowing the warped substrate to be conveyed normally to its exit point. Therefore, this invention satisfies the requirements for bare substrate conveying, inspection, and other operations on warped substrates, effectively avoiding jamming during transport, reducing the risk of substrate damage, and improving the efficiency of bare substrate conveying and inspection operations.

[0034] Combination Figures 1-13 As shown, the substrate conveying mechanism 100 provided by this utility model is particularly suitable for use in packaging processes in conjunction with an optical inspection machine 300. It is used to convey the substrate 200 to the optical inspection machine 300 for automatic inspection. After the inspection is completed, the substrate 200 is conveyed until it exits. During the conveying process, the warped substrate 200 can be effectively prevented from being jammed.
[0035] Understandably, the substrate conveying mechanism 100 is not limited to working with the optical inspection machine 300. It is equally feasible and equally effective to work with corresponding equipment in other processes to convey the substrate 200 for other processing steps, and to prevent the warped substrate 200 from being jammed during the conveying process.
[0036] Of course, the substrate conveying mechanism 100 is not limited to conveying the substrate 200; it is also feasible to use it to convey other sheet-like products that may warp.
[0037] Let's combine the following... Figure 1-3 , Figure 11-12 As shown, in one embodiment of this utility model, the substrate conveying mechanism 100 includes at least a track assembly 110, a pressing assembly 120, and a mounting wall 130. The mounting wall 130 is vertically mounted and has opposing first side surfaces 131 and second side surfaces 132. The track assembly 110 includes at least a conveying track 111 and a first driving member 112. The conveying track 111 is mounted on the first side surface 131 and along a first direction (…). Figure 1 , Figure 11-12 Extending in the direction indicated by the middle arrow F1, this first direction is the conveying direction of the substrate 200. The first driving member 112 is connected to the conveying track 111 and is used to drive the conveying track 111 to move or rotate to convey the substrate. The pressing assembly 120 includes at least a pressing plate 121 and a second driving member 122. The pressing plate 121 is disposed above the mounting wall 130, and the second driving member 122 is connected to the pressing plate 121 and is used to drive the pressing plate 121 along the vertical direction (…). Figure 11-12 The plate 121 moves up and down (in the direction indicated by the middle arrow F2) so that the pressure plate 121 can press the substrate 200 on the transport track 111 and disengage the substrate 200 from the transport track 111.
[0038] The following is combined with Figure 1 , Figure 10-12 As shown, in one specific embodiment of this utility model, the substrate conveying mechanism 100 includes two track assemblies 110, two holding assemblies 120, and two mounting walls 130. The two mounting walls 130 are spaced apart, with their first side surfaces 131 located on the inner side and their second side surfaces 132 located on the outer side. The distance between them is determined by the distance between the opposite sides of the substrate 200 to be conveyed. A track assembly 110 is mounted on the first side surface 131 of each mounting wall 130. Both track assemblies 110 extend along a first direction and are located at the same horizontal height. The two conveying tracks 111 support and convey the opposite sides of the substrate 200, that is, the substrate 200 is conveyed in a suspended state, which can avoid crushing or damaging the chips, packages, and other components on the substrate 200. Each mounting wall 130 has a pressing assembly 120 installed on its second side 132. The pressing plate 121 of each pressing assembly 120 is located above the mounting wall 130. The two pressing plates 121 are symmetrically arranged. The two pressing plates 121 are driven to rise and fall synchronously by two second driving members 122, so that the opposite sides of the substrate 200 are pressed at the same time or detached at the same time. In this way, the warped substrate 200 can be smoothly transported to the bottom of the pressing plate 121 for pressing and testing, effectively avoiding the situation of jamming of the warped substrate 200 during transportation.
[0039] Understandably, the number of track assemblies 110, holding assemblies 120, and mounting walls 130 is not limited to that in this embodiment, but can be flexibly set according to the size, thickness, etc. of the substrate 200 to be transported. For example, when the width of the substrate 200 is large, track assemblies 110 can be added, such as transporting the substrate 200 by three spaced track assemblies 110. In this way, the position of the track assemblies 110 installed on the mounting wall 130 can be adjusted accordingly, which is a conventional method well known to those skilled in the art.
[0040] The following is combined with Figure 10-13As shown, in one specific embodiment of this utility model, the position of the holding plate 121 corresponds to the position of the optical inspection machine 300. Thus, when the substrate 200 is transported to the position of the holding plate 121, the second driving member 122 drives the holding plate 121 to descend and hold the opposite sides of the substrate 200, without affecting the optical inspection machine 300's inspection of the substrate 200. After inspection is completed, the second driving member 122 drives the holding plate 121 to rise and detach from the substrate 200, allowing the substrate 200 to continue being transported by the track assembly 110. In this way, even a warped substrate 200 can smoothly enter under the holding plate 121 for inspection during transport, and effectively prevents the warped substrate 200 from being blocked by the holding plate 121, causing jamming or other issues.
[0041] Combination Figure 6-7 As shown, in a preferred embodiment, the maximum height h between the highest position of the pressure plate 121 after it rises and the conveying surface 111a of the conveying track 111 is 32 mm, thus enabling the conveying and inspection of substrates 200 with a warpage height of less than 32 mm. Of course, the highest position of the pressure plate 121 after it rises is not limited to that in this embodiment and can be flexibly set according to actual usage needs.
[0042] Recombined Figures 1-3 As shown, in one embodiment of this utility model, the conveying track 111 is a ring-shaped conveyor belt, such as a ring-shaped belt. The first driving member 112 is connected to the conveyor belt and drives the conveyor belt to rotate to convey the substrate 200.
[0043] More specifically, the track assembly 110 also includes a plurality of drive wheels 113, which are mounted on the first side 131 of the mounting wall 130. The conveyor belt is wound around each of the drive wheels 113 in a ring shape. One drive wheel 113 is connected to a first drive member 112. When the first drive member 112 drives the drive wheel 113 connected to it to rotate, it can drive the ring-shaped conveyor belt to rotate, thereby realizing the conveying of the substrate 200 placed above the conveyor belt.
[0044] It should be noted that, in Figure 1-2 The diagram only schematically illustrates the method of mounting the drive pulley 113 to the conveyor belt; the number and mounting method of the drive pulley 113 are not limited to those shown in the diagram. In actual production, the method of mounting the drive pulley 113 to the conveyor belt in a ring shape is the conventional method in this field.
[0045] Combination Figures 1-2As shown, in a preferred embodiment, the first driving component 112 is a motor, which drives a transmission wheel 113 to rotate, thereby realizing the rotation of the conveyor belt. This reduces the cost of the driving component and simplifies the driving method. Of course, other driving components can also be used for the first driving component 112.
[0046] Understandably, the conveying track 111 is not limited to a ring structure. For example, in other embodiments, the conveying track 111 may also be plate-shaped, strip-shaped, or other structures. The first driving member 112 drives the conveying track 111 to move along the first direction, which can also achieve the carrying and conveying of the substrate 200.
[0047] The following is combined with Figure 1 , Figure 3-4 As shown, in one embodiment of this utility model, the pressing assembly 120 further includes a connecting plate 123, a slider 124, and a guide rail 125. The guide rail 125 is fixed to the second side 132 of the mounting wall 130 and extends vertically. The connecting plate 123 is slidably connected to the guide rail 125 via the slider 124. The upper end of the connecting plate 123 is connected to the pressing plate 121, and the lower end of the connecting plate 123 is connected to a second driving member 122. The second driving member 122 drives the connecting plate 123 to slide up and down along the guide rail 125, thereby driving the pressing plate 121 to rise and fall, making the driving of the pressing plate 121 more convenient and effortless.
[0048] Combination Figure 1 , Figure 3 As shown, in a preferred embodiment, when the length of the holding plate 121 is relatively large, each holding component 120 may be provided with multiple second driving members 122. The multiple second driving members 122 are connected to the lower end of the connecting plate 123 at intervals. The multiple second driving members 122 synchronously drive the connecting plate 123 to slide up and down, thereby driving the holding plate 121 to rise and fall. This makes the force on the holding plate 121 more balanced and the rising and falling more stable, thereby avoiding damage to the substrate 200.
[0049] In a preferred embodiment, the second driving component 122 is a cylinder, which drives the pressure plate 121 to rise and fall, making the driving process simple, labor-saving, and cost-effective. Of course, other driving components can also be used for the second driving component 122.
[0050] The following is combined with Figures 4-7 As shown, in a preferred embodiment of this utility model, after the conveying track 111 is installed on the first side 131 of the mounting wall 130, the conveying surface 111a formed by the conveying track 111 is lower than the top surface 133 of the mounting wall 130, such as... Figure 5 , Figure 7As shown. Thus, the first side surface 131 of the mounting wall 130 forms a limiting surface, which can limit the side portion of the substrate 200 supported on the transport surface 111a, preventing the substrate 200 from shifting during transport and damaging structures such as the package on the substrate 200. Meanwhile, compared to Figure 14 As shown in the prior art, the upper part of the conveying surface 111a of the conveying track 111 is seamless, which makes it suitable for bare board conveying of ultra-thin substrate 200 (e.g., substrate 200 with a thickness of 0.1 mm). That is, the ultra-thin substrate 200 can be directly placed on the conveying surface 111a and conveyed, and the ultra-thin substrate 200 will not be stuck by the gap, effectively avoiding the jamming problem that exists when conveying ultra-thin substrate 200 in the prior art.
[0051] The following is combined with Figures 8-9 As shown, in a preferred embodiment of this utility model, the conveying surface 111a formed by the conveying track 111 is higher than the top surface 133 of the mounting wall 130. More preferably, after installation, the bottom 111b of the conveying track 111 is flush with the top surface 133 of the mounting wall 130, so that the entire conveying track 111 is located above the top surface 133 of the mounting wall 130. Figure 9 As shown.
[0052] In this structural configuration, the track assembly 110 also includes a limiting block 114, which is mounted on the top surface 133 of the mounting wall 130. Simultaneously, the limiting block 114 is located on the side of the conveying track 111. Figure 9 As shown, the limiting block 114 is used to limit the substrate 200 conveyed on the conveying track 111 in the lateral direction, which intersects with the conveying direction of the conveying track 111.
[0053] In this embodiment, the top surface of the limiting block 114 is higher than the conveying surface 111a of the conveying track 111, and the bottom surface of the limiting block 114 is lower than the conveying surface 111a of the conveying track 111. Combined with... Figure 14 As shown, in the prior art, the limiting block 114' is located above the conveying track 111' and its position can be adjusted laterally to accommodate the conveying of substrates 200 of different widths. Simultaneously, the limiting block 114' limits the substrate 200 on the conveying track 111'. However, a gap is formed between the limiting block 114' and the upper part of the conveying track 111'. During the transmission of the ultrathin substrate 200, the ultrathin substrate 200 often gets stuck in the aforementioned gap, causing the plate to fail. In contrast, this application... Figure 14As shown in the prior art, the position of the conveying track 111 is raised or the thickness of the conveying track 111 is increased, and the conveying surface 111a of the conveying track 111 is higher than the bottom surface of the limiting block 114, while the conveying surface 111a of the conveying track 111 is lower than the top surface of the limiting block 114, thereby forming a seamless planar track. That is to say, there is no longer a gap between the top of the conveying track 111 and the limiting block 114, which is suitable for bare board conveying of ultra-thin substrate 200 and effectively avoids the board jamming problem of ultra-thin substrate 200 conveying in the prior art.
[0054] Continue to combine Figures 8-9 As shown, in this embodiment, the limiting block 114 is adjustablely mounted on the top surface 133 of the mounting wall 130 in the lateral direction. The adjustment direction of the limiting block 114 is intersected with the conveying direction of the conveying track 111, specifically perpendicular to the conveying direction of the conveying track 111.
[0055] Combination Figure 1 As shown, the adjustment direction of the limiting block 114 is perpendicular to the first direction ( Figure 1 The horizontal direction (as indicated by the middle arrow F1) is shown below. Figure 9 The direction indicated by the middle arrow F3. Adjust the lateral direction of the limiting block 114 ( Figure 9 (As indicated by the arrow F3) position, and by changing the transport track 111 of different widths, it can also adapt to the transport of substrates 200 of different widths.
[0056] Recombined Figure 1-2 , Figure 10-12 As shown, in one embodiment of this utility model, the substrate conveying mechanism 100 further includes a detection element 140 and a controller (not shown). The detection element 140 is installed on at least one of the track assembly 110, the holding assembly 120, and the mounting wall 130, and is used to detect whether the substrate 200 has reached the position of the holding plate 121. The controller is electrically connected to the detection element 140 and the second driving element 122, respectively. The controller controls the second driving element 122 to drive the holding plate 121 to move up and down based on the detection result of the detection element 140. The detection element 140 is used to detect the position of the substrate 200, making the position determination of the substrate 200 more accurate, thereby driving the holding plate 121 to accurately hold the substrate 200 and avoiding jamming caused by the holding plate 121 contacting or blocking the substrate 200.
[0057] In one specific embodiment, the detection element 140 is mounted on a first side 131 of one of the mounting walls 130, and in a first direction, the detection element 140 is located below the end of the holding plate 121. Thus, when the detection element 140 detects the substrate 200, it indicates that the substrate 200 has been transported to the position below the holding plate 121. At this time, the controller, based on the detection signal from the detection element 140, controls the second driving element 122 to actuate and drive the holding plate 121 to descend, so that the holding plate 121 presses against the opposite two sides of the substrate 200, as shown below. Figure 12 As shown. After the substrate 200 is detected, the controller controls the second drive member 122 to operate again to drive the pressure plate 121 to rise and detach from the substrate 200, so that the substrate 200 can continue to be transported by the track assembly 110.
[0058] In a preferred embodiment, the detection element 140 is an optical fiber sensor, but it is not limited to this and other detection devices can also be used.
[0059] Recombined Figures 1-13 The working principle and process of the substrate conveying mechanism 100 of this utility model are explained as shown.
[0060] First combine Figure 10-11 As shown, the opposite two sides of the substrate 200 are supported on two conveying tracks 111, and are conveyed by the two conveying tracks 111 along a first direction ( Figure 10 (In the direction indicated by the middle arrow F1) During the transport process, the two holding plates 121 are in an elevated state. Therefore, even if the substrate 200 is warped, it will not affect its transport, and no jamming or other issues will occur during transport. The warped substrate 200 can be smoothly transported to the bottom of the holding plate 121.
[0061] In addition, combined Figure 6-9 As shown, based on the arrangement of the conveying track 111 in this application, since a seamless conveying surface 111a is formed above the conveying track 111, the ultra-thin substrate 200 can be directly placed on the conveying surface 111a and conveyed, and the ultra-thin substrate 200 will not be stuck by the gap, effectively avoiding the jamming problem that exists when conveying the ultra-thin substrate 200 in the prior art.
[0062] When the substrate 200 is conveyed below the holding plate 121, and the detection element 140 detects the substrate 200, such as Figure 11 The state shown. At this time, the controller, based on the detection signal from the detection element 140, controls the two second driving elements 122 to move synchronously, thereby simultaneously driving the two pressure plates 121 along the vertical direction ( Figure 11 As indicated by the middle arrow F2, the plates descend, causing the two pressing plates 121 to press against the opposite sides of the substrate 200. Figure 12 As shown.
[0063] Then, the substrate 200 is inspected by the optical inspection machine 300, such as... Figure 13 As shown. After the detection is completed, the controller controls the two second drive units 122 to move synchronously again, and at the same time drives the two pressure plates 121 to rise to disengage from the substrate 200, so that the substrate 200 can continue to be transported by the track assembly 110 until it exits.
[0064] In summary, because the substrate conveying mechanism 100 of this utility model sets the pressing plate 121 of the pressing assembly 120 as a movable structure and provides a second driving member 122 to drive the pressing plate 121 to rise and fall, the pressing plate 121 can press the substrate 200 on the conveying track 111 and can detach from the substrate 200. Thus, when the substrate 200 has not reached the position of the pressing plate 121, the pressing plate 121 is in a raised state, so that the warped substrate 200 can be smoothly conveyed by the conveying track 111 without jamming. When the substrate 200 reaches the position of the pressing plate 121, the pressing plate 121 is driven to fall and press on the warped substrate 200, thereby clamping the substrate 200 for detection or other operations. When the detection or other operations are completed, the pressing plate 121 is driven to rise and detach from the substrate 200, so that the warped substrate 200 can be normally conveyed by the conveying track 111 to exit. Therefore, this application can meet the requirements of bare board transportation, inspection or other operations of warped substrate 200, and can effectively avoid problems such as board jamming that occur during the transportation of warped substrate 200, reduce the risk of substrate 200 damage, and improve the efficiency of bare board transportation, inspection and other operations of substrate 200.
[0065] The structures of other parts of the substrate conveying mechanism 100, the structure of the optical inspection machine 300, and the inspection methods involved in this utility model are all conventional structures and methods well known to those skilled in the art, and will not be described in detail here.
[0066] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
