Abstract
Description
Technical Field
[0001] This application relates to the field of material transportation technology, and in particular to a material feeding and screening device and a testing equipment. Background Technology
[0002] In the fields of machinery manufacturing, electronic product assembly, and automotive parts production, products typically require defect detection and dimensional measurement of their components or complete machines before leaving the factory in order to eliminate defective or non-compliant products.
[0003] Traditional testing equipment typically employs the following layout: a screening device is installed behind the testing station. After testing, the screening device sorts defective products to a dedicated defective product conveyor line; while qualified products continue along the original conveyor line into subsequent processes.
[0004] However, when the aforementioned traditional equipment is used to inspect large-sized products, the accompanying screening devices and defective product conveyor lines also need to be enlarged accordingly. This significantly increases the equipment's footprint and is detrimental to the optimal layout of the production line. Utility Model Content
[0005] Therefore, it is necessary to provide a material feeding and screening device and a testing equipment to address the above problems.
[0006] This application provides a material feeding and screening device, which includes a conveying component, a coating component, a marking component, a distributing component, and a placing component. The conveying component is used to convey workpieces; the coating component is used to coat the top and bottom surfaces of the workpieces with a film, and the coating component includes a first coating part and a second coating part, the first coating part being located on the top side of the conveying component and the second coating part being located on the bottom side of the conveying component; the marking component includes a first support, a driver, and a marking element, the first support being disposed above or below the conveying component, the driver being disposed on the first support, the driver being connected to the marking element, and the driver driving the marking element to move longitudinally; the distributing component is mounted on the conveying component and is used to pick up workpieces; the placing component includes a first placing part and a second placing part; wherein, the conveying component can convey the workpiece to the first placing part, and the distributing component can pick up the workpiece conveyed by the conveying component and transfer it to the second placing part.
[0007] In one embodiment, the marking assembly further includes a connecting frame, a mounting member, and an elastic member, wherein the connecting frame is connected to the driver; the mounting member is fixedly connected to the marking member and is movably disposed on the connecting frame along the driving direction of the driver; and the elastic member is elastically connected between the connecting frame and the mounting member.
[0008] In one embodiment, the marker is detachably disposed on the mounting element.
[0009] In one embodiment, the mounting component includes a first mounting portion, a second mounting portion, and a locking member. One side of the first mounting portion is rotatably connected to the second mounting portion, and the locking member is detachably disposed on the other side of the first mounting portion and the second mounting portion. The first mounting portion and the second mounting portion clamp and fix the marking member.
[0010] In one embodiment, the conveying assembly includes a first conveying component, which includes a pallet and a first clamping roller group. The pallet is used to support the workpiece, and the first clamping roller group includes at least two clamping rollers arranged side by side. The first clamping roller group is located downstream of the pallet, and the clamping rollers are rotatable when driven. The first coating component includes a first material cylinder, and the second coating component includes a second material cylinder. The film wound on the first material cylinder extends from the upstream side of the first clamping roller group to the space between the two clamping rollers. The film wound on the second material cylinder is laid on the top side of the pallet and is used to support the workpiece. The film wound on the second material cylinder extends from the upstream side of the first clamping roller group to the space between the two clamping rollers, and the clamping rollers are used to clamp the workpiece and the film.
[0011] In one embodiment, the conveying assembly further includes a second conveying component located downstream of the first conveying component. The second conveying component includes a second clamping roller group and a conveyor belt structure. The second clamping roller group is located between the first clamping roller group and the conveyor belt structure. The second clamping roller group is used to clamp the workpiece and the film material and transport them to the conveyor belt structure. The conveyor belt structure is used to convey the workpiece and the film material.
[0012] In one embodiment, the first clamping roller group is drivenly connected to the second clamping roller group, and the first clamping roller group and the second clamping roller group rotate synchronously.
[0013] In one embodiment, the conveying assembly includes a second support and a drive component. The second support is disposed between the pallet and the conveyor belt structure. The first clamping roller group includes a first clamping roller and a second clamping roller arranged side by side on the second support. The first clamping roller and the second clamping roller are driven by friction on their outer peripheries. The second clamping roller group includes a third clamping roller and a fourth clamping roller arranged side by side on the second support. The third clamping roller and the fourth clamping roller are driven by friction on their outer peripheries. With reference to the top surface of the pallet, the first clamping roller and the third clamping roller are located on the same side, and the second clamping roller and the fourth clamping roller are located on the opposite side. The drive component is connected to the first clamping roller, and the first clamping roller is also driven by the third clamping roller. The third clamping roller is driven by the conveyor belt structure. The drive connection between the second clamping roller and the fourth clamping roller, and the drive connection between the third clamping roller and the conveyor belt structure, are configured as any one of belt drive, chain drive, and gear drive.
[0014] In one embodiment, the feeding and screening device further includes a cutting component disposed between the first clamping roller group and the second clamping roller group, the cutting component being used to cut the film material.
[0015] This application also provides a testing device, which includes a testing apparatus and a feeding and screening apparatus as described above.
[0016] In the aforementioned feeding and screening device, after the workpiece is coated and marked, it is screened by the material distribution component. In other words, compared with the traditional layout, in this application, good and defective workpieces share the same conveying component and are screened at the material placement component. Therefore, it is not necessary to set up a separate defective product conveying line, which can reduce the space occupation of the testing equipment and facilitate the optimization of the production line layout.
[0017] Furthermore, even workpieces that fail the inspection will be coated on both sides (top and bottom) by the coating assembly, facilitating the stacking and batch transfer of defective workpieces. In other words, coating before unloading reduces the likelihood of new appearance defects caused by interactions between defective workpieces during stacking and transfer, providing a basis for workpiece re-inspection.
[0018] Furthermore, the actuator can drive the marker to move longitudinally, allowing it to shift accordingly as defective products pass by, thus marking the workpieces with defective inspection results. The markings created by the markers effectively distinguish between good and defective workpieces, reducing the risk of confusion between workpieces with different inspection results. This is especially beneficial in processes requiring manual intervention, minimizing the likelihood of workpiece confusion and facilitating sorting and processing. Attached Figure Description

Detailed Implementation
[0031] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0032] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0033] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0034] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0035] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0036] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0037] Traditional inspection equipment typically employs the following layout: a screening device is installed behind the inspection station. After inspection, the screening device sorts defective products to a dedicated defective product conveyor line; while qualified products continue along the original conveyor line to subsequent processes. For example, for surface defect-sensitive parts such as white glass, qualified parts need to be coated after inspection for storage and transportation. When this traditional equipment is used to inspect large-sized products, the corresponding screening device and defective product conveyor line also need to be enlarged. This significantly increases the equipment's footprint, hindering the optimization of production line space. Furthermore, for surface defect-sensitive parts such as white glass, directly stacking them without coating can easily cause scratches between adjacent stacked parts. Since inspection has inherent errors, parts judged as defective usually undergo a re-inspection process. The scratches during the stacking process can cause parts mistakenly judged as defective to become genuinely defective, thus limiting the yield rate.
[0038] To address the aforementioned problems, this application provides a material feeding and screening device, comprising a conveying component, a coating component, a marking component, and a sorting component. The conveying component transports workpieces, the coating component coats all workpieces, and the marking component marks workpieces that are deemed defective. The sorting component then screens the coated and marked workpieces according to the test results. In this material feeding and screening device, since the workpieces are screened after coating and marking, good and defective products share the same conveying component, reducing space occupancy and facilitating optimized production line layout. Furthermore, because the coating component coats all workpieces, the probability of defective workpieces scratching each other is reduced, facilitating re-inspection. Even further, since both good and defective workpieces are coated, it is difficult to visually distinguish between them, especially when manual intervention is required (e.g., manually transferring defective workpieces to a re-inspection station), which can easily lead to workpiece confusion. This application utilizes a marking component to mark defective workpieces, creating strong differentiation, reducing the likelihood of workpiece confusion, and facilitating classification and processing. The following detailed description, in conjunction with the accompanying drawings and specific embodiments, illustrates the feeding and screening device and testing equipment provided in various embodiments of this application.
[0039] Furthermore, to clearly illustrate the material feeding and screening devices provided in the various embodiments of this application, the distribution of each device and component will be described below in terms of the "upstream side" and "downstream side" in the workpiece conveying direction. It is understood that in the manufacturing field, the "upstream side" of a device / component refers to the side the workpiece passes through first when it is conveyed to the location of that device / component, and the "downstream side" of a device / component refers to the side the workpiece passes through last when it is conveyed to the location of that device / component. As shown in the accompanying drawings, the upstream side can be referred to as the side indicated by reference numeral SY, and the downstream side can be referred to as the side indicated by reference numeral XY.
[0040] See Figure 1 One embodiment of this application provides an inspection device, which includes an inspection unit and a material screening unit. The inspection unit performs defect detection and dimensional measurement on the workpiece. When the inspection unit does not find any defects in the workpiece, only some defects with permissible errors, and the dimensions meet the expected error range, the workpiece can be judged as a good product; otherwise, it is a defective product. The material screening unit can classify the workpieces judged as good products and the workpieces as defective products for different processing.
[0041] Furthermore, the feeding and screening device can also coat the workpieces to reduce the risk of them scratching each other when stacked.
[0042] See Figure 2 and Figure 3 , Figure 2 This diagram shows an isometric view of a feeding and screening device according to an embodiment of the present application. Figure 3 for Figure 2 The above view shows the feeding and screening device. An embodiment of the feeding and screening device 10 provided in this application includes a conveying component 100, a film covering component 200, a marking component 300, a material separating component 400, and a material placing component 500. The conveying component 100 is used to convey the workpiece 20, and the conveying component 100 can convey the workpiece 20 to the location of the other four components.
[0043] The coating assembly 200 is used to coat the top and bottom surfaces of the workpiece 20. The coating assembly 200 includes a first coating component 210 and a second coating component 220. The first coating component 210 is located on the top side of the conveying assembly 100 and can coat the top surface of the workpiece 20. The second coating component 220 is located on the bottom side of the conveying assembly 100 and can coat the bottom surface of the workpiece 20. The marking assembly 300 includes a first support 310, a driver 320, and a marking element 330. The first support 310 is located above or below the conveying assembly 100, and the driver 320 is located on the first support 310. The driver 320 is connected to the marking element 330 and drives the marking element 330 to move longitudinally. Thus, the marking element 330 can move longitudinally accordingly when defective products pass by, marking workpieces 20 whose inspection results are defective. The marking formed by the marking element 330 can effectively distinguish between good and defective workpieces 20, reducing the risk of confusion between workpieces 20 with different test results. This is especially beneficial in processes requiring manual intervention, as it lowers the likelihood of workpiece confusion and facilitates classification. The same principle applies to marking good workpieces with the marking element 330.
[0044] The material sorting component 400 is mounted on the conveying component 100 and is used to pick up the workpiece 20. The placement component 500 includes a first placement component 510 and a second placement component 520. The conveying component 100 can convey the workpiece 20 to the first placement component 510, and the material sorting component 400 can pick up the workpiece 20 conveyed by the conveying component 100 and transfer it to the second placement component 520.
[0045] In the aforementioned feeding and screening device 10, after the workpiece 20 is coated and marked, it is screened by the material distribution component 400. In other words, compared to the traditional layout, in this application, good and defective workpieces 20 share the same conveying component 100, and screening is performed again at the material placement component 500. This eliminates the need for a separate defective product conveying line, reducing the space occupied by the inspection equipment and facilitating optimized production line layout. Furthermore, even workpieces 20 that are defective will be coated on both sides (top and bottom) by the coating component 200, facilitating the stacking and batch transfer of defective workpieces 20. In other words, coating before feeding reduces the probability of new appearance defects caused by the interaction of defective workpieces 20 during stacking and transfer, providing a basis for re-inspection of workpieces 20.
[0046] As one example, the conveying component 100 can convey the workpiece 20 that is determined to be good to the first placement component 510, and the sorting component 400 can pick up the workpiece 20 that is determined to be defective and transfer it to the second placement component 520, thus realizing the classification and processing of good workpiece 20 and defective workpiece 20.
[0047] Please see Figure 4 and Figure 5 In one embodiment, the conveying assembly 100 includes a first conveying component 101 and a second conveying component 102. The first conveying component 101 is used to convey the workpiece 20 to be coated after the inspection is completed, and the second conveying component 102 is used to convey the workpiece 20 after coating. That is, the coating assembly 200 coats the workpiece 20 at the first conveying component 101 and the second conveying component 102.
[0048] The first conveying component 101 includes a pallet 110 and a first clamping roller assembly 120. The pallet 110 supports the workpiece 20, and the first clamping roller assembly 120 clamps the workpiece 20. The first clamping roller assembly 120 includes at least two clamping rollers (i.e., the first clamping roller 121 and the second clamping roller 122 mentioned below), which are arranged side by side. The first clamping roller assembly 120 is located on the downstream side XY of the pallet 110. The clamping rollers can rotate when driven, and when the clamping rollers rotate, they can drive the clamped workpiece 20 to move tangentially along the clamping rollers to convey the workpiece 20.
[0049] The first coating component 210 includes a first barrel 211 for winding film 30. The film 30 wound on the first barrel 211 extends from the upstream side SY of the first clamping roller group 120 to between the two clamping rollers. The second coating component 220 includes a second barrel 221 for winding film 30. The film 30 wound on the second barrel 221 is laid on the top side of the support plate 110 and is used to support the workpiece 20. The film 30 wound on the second barrel 221 extends from the upstream side SY of the first clamping roller group 120 to between the two clamping rollers, which are used to clamp the workpiece 20 and the film 30. (See reference...) Figure 5 In conjunction with the foregoing, since the first coating component 210 is located on the top side of the conveying assembly 100, and the workpiece 20 is supported by the pallet 110 of the conveying assembly 100, the film 30 wound by the first roller 211 can extend from the top surface of the workpiece 20 into the space between the two clamping rollers. The film 30 wound by the second roller 221 is laid on the top side of the pallet 110 and used to support the workpiece 20; that is, the film 30 wound by the second roller 221 is located at the bottom of the workpiece 20. Thus, at the clamping points of the two rollers, the two portions of film 30 are located on the top and bottom surfaces of the workpiece 20, respectively. The rollers clamp the workpiece 20 and the film 30, which can roll and smooth the film 30 located on the top and bottom surfaces of the workpiece 20, improving the adhesion effect of the film 30.
[0050] Furthermore, since the first clamping roller group 120 clamps the workpiece 20 and the film material 30, when the clamping rollers rotate, they apply a tangential driving force to the workpiece 20 and the film material 30. This tangential driving force can drive the workpiece 20 and the film material 30 to be conveyed downstream (XY). Further, since the film material 30 of the second feed cylinder 221 is laid on the pallet 110 and supports the workpiece 20, the film material 30 laid on the pallet 110, under the traction of the tangential driving force of the first clamping roller group 120, can drive the workpiece 20 to move closer to the first clamping roller group 120, and finally be conveyed downstream (XY) of the first clamping roller group 120. At this time, the first clamping roller group 120, combined with the film material 30 laid on the pallet 110, can function as a conveyor belt-like conveying method. It should be noted that in this embodiment, the workpiece 20 can be transported by the first clamping roller group 120 combined with the membrane material 30 laid on the pallet 110, so there is no need to configure an additional conveying mechanism, and the overall structure is simple.
[0051] Please continue reading. Figure 5 In one embodiment, the first conveying component 101 further includes a first guide roller 103 and a second guide roller 104. The first guide roller 103 is located on the downstream side XY of the pallet 110, and the film material 30 wound on the first barrel 211 extends to the first clamping roller group 120 via the first guide roller 103. It is understood that by configuring the first guide roller 103, the extension direction of the film material 30 wound on the first barrel 211 can be changed, so that the film material 30 is arranged in the expected extension direction for smooth film coating.
[0052] Similarly, the second guide roller 104 is located on the upstream side SY of the pallet 110. It is understood that the second coating assembly 200 is located at the bottom of the pallet 110, and the film 30 wound by the second cylinder 221 can be wound from the bottom of the pallet 110 to the top side of the pallet 110 via the second guide roller 104 to lay on the top side of the pallet 110 and support the workpiece 20. By configuring the second guide roller 104, the extension direction of the film 30 wound by the second cylinder 221 can be changed, so that the film 30 is laid on the top side of the pallet 110 in the desired extension direction, so as to transport the workpiece 20 and facilitate smooth coating.
[0053] Please continue reading. Figure 4 and Figure 5In one embodiment, the feeding and screening device 10 further includes a base (not shown in the figure, the same below), and the conveying component 100, the film-coating component 200, the marking component 300, the material-distributing component 400, and the material-placing component 500 are all disposed on the base. Further, the first conveying component 101 includes a first upright 212, and a first material cylinder 211 is rotatably disposed on the first upright 212. The first material cylinder 211 is supported by the first upright 212, allowing it to rotate stably in a relatively independent position for material feeding. Similarly, the second conveying component 102 includes a second upright 222, and a second material cylinder 221 is rotatably disposed on the second upright 222. The second material cylinder 221 is supported by the second upright 222, allowing it to rotate stably in a relatively independent position for material feeding.
[0054] Furthermore, the first support 310 mentioned above, as well as the second support 150 and the third support 410 mentioned below, can all be mounted on the base.
[0055] Please see Figures 4 to 6 In one embodiment, the second conveying component 102 is located downstream of the first conveying component 101 (XY side). The second conveying component 102 includes a second clamping roller group 130 and a conveyor belt structure 140. The second clamping roller group 130 is located between the first clamping roller group 120 and the conveyor belt structure 140. The second clamping roller group 130 is used to clamp the workpiece 20 and the film material 30 and transport them to the conveyor belt structure 140. The conveyor belt structure 140 is used to transport the workpiece 20 and the film material 30. It is understood that the conveyor belt structure 140 can actively transport the workpiece 20. After receiving the film-coated workpiece 20 from the first clamping roller group 120, the second clamping roller group 130 can transfer the workpiece 20 to the conveyor belt structure 140 to achieve continuous conveying.
[0056] Please see Figure 5 In one embodiment, the feeding and screening device 10 further includes a cutting component 600, which is disposed between the first clamping roller group 120 and the second clamping roller group 130. The cutting component 600 is used to cut the film material 30. Since the film material 30 is wound in the form of a continuous strip on the first material cylinder 211 / second material cylinder 221 before being cut, the cutting component 600 can cut the film material 30 covering adjacent workpieces 20, making the positions of each film-covered workpiece 20 independent, which is convenient for subsequent storage and transportation. In this embodiment, since both the first clamping roller group 120 and the second clamping roller group 130 clamp the workpiece 20 and the film material 30, both can tangentially drive the workpiece 20 and the film material 30 for transportation. Therefore, by arranging the cutting component 600 between the first clamping roller group 120 and the second clamping roller group 130, even if the film material 30 between adjacent workpieces 20 is cut, the continuous conveying of the workpieces 20 is not affected.
[0057] In one embodiment, the first clamping roller group 120 and the second clamping roller group 130 are drive-connected, and the first clamping roller group 120 and the second clamping roller group 130 rotate synchronously. This reduces the risk of the workpiece 20's surface film 30 being torn or wrinkled due to asynchronous rotation when the workpiece 20 is simultaneously clamped by the first clamping roller group 120 and the second clamping roller group 130. Furthermore, the first clamping roller group 120 and the second clamping roller group 130 share the same drive source, simplifying the structure and saving costs.
[0058] Furthermore, the second clamping roller group 130 can also be connected to the conveyor belt structure 140 for synchronous movement, which facilitates the smooth transport of the workpiece 20, simplifies the structure, and reduces costs.
[0059] Please see Figure 6 Combined Figure 4 and Figure 5 In one embodiment, the conveying assembly 100 includes a second support 150 and a drive member 160. The second support 150 is disposed between the pallet 110 and the conveyor belt structure 140. Each of the clamping rollers included in the first clamping roller group 120 and each of the clamping rollers included in the second clamping roller group 130 are respectively disposed on the second support 150.
[0060] like Figure 5 and Figure 6 The first clamping roller group 120 includes a first clamping roller 121 and a second clamping roller 122, which are arranged side-by-side on the second support 150. The first clamping roller 121 and the second clamping roller 122 are driven by frictional transmission on their outer circumferences. The second clamping roller group 130 includes a third clamping roller 131 and a fourth clamping roller 132, which are arranged side-by-side on the second support 150. The third clamping roller 131 and the fourth clamping roller 132 are driven by frictional transmission on their outer circumferences. Figure 5 With reference to the top surface of the pallet 110, the first clamping roller 121 and the third clamping roller 131 are located on the same side, while the second clamping roller 122 and the fourth clamping roller 132 are located on the opposite side. Regarding the peripheral friction drive of the above-mentioned clamping rollers, it should be noted that each clamping roller has a columnar structure, and each clamping roller can be driven in the form of friction wheel drive. It is understood that the clamping rollers may have an elastic structure (e.g., an elastic soft rubber covering the outer periphery) or the clamping rollers may be elastically movable. When the workpiece 20 and the film material 30 are not clamped between the two clamping rollers of the peripheral friction drive, there is a contact side between the two clamping rollers. When one clamping roller rotates, it transmits the motion to the other through friction on the contact side. When the workpiece 20 and the film material 30 are clamped between the two clamping rollers of the peripheral friction drive, although there is no longer a contact side between them, the two clamping rollers can still be driven by the workpiece 20 and the film material 30 clamped between them, so that the two clamping rollers rotate synchronously and smooth the film material covering the workpiece 20.
[0061] like Figure 6The driving component 160 is connected to the first clamping roller 121. When the driving component 160 drives the first clamping roller 121 to rotate, the first clamping roller 121 can drive the second clamping roller 122 to rotate through friction. The first clamping roller 121 is also connected to the third clamping roller 131, which can rotate accordingly. At the same time, the third clamping roller 131 also drives the fourth clamping roller 132 to rotate through friction, causing the second clamping roller group 130 to rotate to transport the workpiece 20. Furthermore, the third clamping roller 131 is also connected to the conveyor belt structure 140, so when the third clamping roller 131 rotates, it can drive the conveyor belt structure 140 to move together. Thus, the conveying assembly 100 can achieve synchronous movement of all parts with a single driving source, realizing smooth conveying.
[0062] In one embodiment, the drive member 160 is connected to one end of the first clamping roller 121, and the other end of the first clamping roller 121 is drivenly connected to the third clamping roller 131, so as to make full use of the space to arrange the drive member and the transmission member. For the third clamping roller 131, one end is drivenly connected to the first clamping roller 121, and the other end is drivenly connected to the conveyor belt structure 140, so as to make full use of the space to arrange the drive member and the transmission member.
[0063] In one embodiment, the transmission connection between the first clamping roller 121 and the third clamping roller 131, and the transmission connection between the third clamping roller 131 and the conveyor belt structure 140, are configured as any one of belt drive, chain drive, and gear drive. Please refer to... Figure 5 , Figure 7 and Figure 8 As one example, the conveying assembly 100 also includes a first transmission component 170 and a second transmission component 180. The first transmission component 170 is driveably connected between a first clamping roller 121 and a third clamping roller 131, and the second transmission component 180 is driveably connected between the third clamping roller 131 and the conveyor belt structure 140. Figure 6 and Figure 8 The first transmission component 170 includes a first driving pulley 171, a first driven pulley 172, and a first transmission belt 173. The first transmission belt 173 is wound around the first driving pulley 171 and the first driven pulley 172, enabling them to be driven together. The first driving pulley 171 is connected to the first clamping roller 121, and the first driven pulley 172 is connected to the third clamping roller 131. Thus, the first transmission component 170 enables the first clamping roller 121 and the third clamping roller 131 to be driven together. Figure 5 and Figure 7The second transmission component 180 includes a second driving pulley 181, a second driven pulley 182, and a second transmission belt 183. The second transmission belt 183 wraps around the second driving pulley 181 and the second driven pulley 182, enabling them to be driven together. The second driving pulley 181 is connected to the third clamping roller 131, and the second driven pulley 182 is connected to the conveyor belt structure 140. Thus, the second transmission component 180 enables the third clamping roller 131 to be driven together with the conveyor belt structure 140. Of course, the above transmission connection method can also be configured into other transmission connection methods according to requirements, which will not be elaborated here.
[0064] Please see Figure 7 In one embodiment, the conveyor belt structure 140 includes a drive shaft 141, a driven shaft 142, and a transmission belt 143. The transmission belt 143 is wound around the drive shaft 141 and the driven shaft 142, so that the driven shaft 142 rotates synchronously with the drive shaft 141. The third clamping roller 131 is connected to the drive shaft 141 through the second transmission component 180.
[0065] Please see Figure 8 Combined Figure 6 In one embodiment, the conveying assembly 100 further includes an adjusting component 190. Some of the clamping rollers are connected to the second support 150 via the adjusting component 190. The adjusting component 190 can adjust the distance between the clamping rollers arranged side-by-side. The adjusting component 190 includes an end seat 191 and an adjusting driver 192. The adjusting driver 192 is disposed on the second support 150, and the end seat 191 is movably disposed on the second support 150. The ends of some of the clamping rollers are connected to the second support 150 via the end seat 191, and the adjusting driver 192 is connected to the end seat 191 to adjust the position of the end seat 191, thereby changing the distance between the clamping rollers. As one example, the ends of the second clamping roller 122 and the fourth clamping roller 132 can be connected to the second bracket 150 via the end seat 191. By adjusting the longitudinal position of the end seat 191 via the adjustment driver 192, the distance between the second clamping roller 122 and the first clamping roller 121, as well as the distance between the fourth clamping roller 132 and the third clamping roller 131, can be adjusted, so that each clamping roller group can clamp and drive the workpiece 20 and the film 30 to move.
[0066] In one embodiment, the rotation axes of the clamping rollers included in the conveying assembly 100 are parallel to each other, and the rotation axes of each clamping roller are perpendicular to the conveying direction of the workpiece 20 (i.e., the second direction S2). That is, the axes of the first clamping roller 121, the second clamping roller 122, the third clamping roller 131, the fourth clamping roller 132, the drive shaft 141, and the driven shaft 142 are parallel to each other and are all perpendicular to the conveying direction of the workpiece 20 (i.e., the second direction S2).
[0067] Please see Figure 9 Combined Figure 7In one embodiment, a cutting assembly 600 is disposed on a second support 150. The cutting assembly 600 includes a cutter 610 and a cutting driver 620. The cutting driver 620 is disposed on the second support 150 and connected to the cutter 610 to drive the cutter 610 to move in a direction perpendicular to the conveying direction of the workpiece 20. Thus, when the film 30 between adjacent workpieces 20 is aligned with the cutter 610, controlling the cutting driver 620 to drive the cutter 610 to cut the film 30 between adjacent workpieces 20.
[0068] Please refer to it again. Figure 1 and Figure 3 In one embodiment, the marking component 300 is located on the downstream side XY of the coating component 200. Therefore, the marking component 300 is used to mark the coated workpiece 20. That is, the marking component 330 can form a mark on the film 30 covering the workpiece 20, thereby reducing the probability of the marking action damaging the workpiece 20.
[0069] Please see Figure 2 and Figure 3 In one embodiment, the marking component 300 may be aligned with the conveyor belt structure 140 to mark the coated workpiece 20.
[0070] Please see Figure 10 In one embodiment, the marking assembly 300 further includes a connecting frame 340, a mounting member 350, and an elastic member 360. The marking member 330 is disposed on the mounting member 350, the mounting member 350 is disposed on the connecting frame 340, and the elastic member 360 is elastically connected between the connecting frame 340 and the mounting member 350.
[0071] The connecting frame 340 is connected to the driver 320, so when the driver 320 drives the connecting frame 340 to move, it can also drive the mounting member 350 and the marking member 330 to move accordingly. The mounting member 350 and the marking member 330 are fixedly connected, and the mounting member 350 is movably disposed on the connecting frame 340 along the driving direction of the driver 320 (i.e., the third direction S3). That is to say, when it is necessary to mark the workpiece 20, the connecting frame 340 can drive the mounting member 350 and the marking member 330 to move longitudinally to form a mark on the designated workpiece 20. Furthermore, since the elastic member 360 is connected between the mounting member 350 and the connecting frame 340, and the mounting member 350 is movably disposed on the connecting frame 340, the marking member 330 can maintain flexible contact with the workpiece 20. When the contact force is too large, the mounting member 350 can compress the elastic member 360 and retract longitudinally to reduce the probability of damage to the workpiece 20 due to excessive contact force.
[0072] In one embodiment, the marker 330 can form a mark on a designated workpiece 20 in a colored manner. For example, the marker 330 can be configured as an element such as a marker or watercolor pen that can form colored marks on the surface of the workpiece 20.
[0073] In one embodiment, the marker 330 is detachably disposed on the mounting member 350 so as to allow for removal and replacement of the marker 330.
[0074] Please continue reading. Figure 10 In one embodiment, the mounting member 350 includes a first mounting portion 351, a second mounting portion 352, and a locking member 355. One side of the first mounting portion 351 is rotatably connected to the second mounting portion 352. The locking member 355 is detachably disposed on the other side of the first mounting portion 351 and the second mounting portion 352 to lock or release the first mounting portion 351 and the second mounting portion 352. The first mounting portion 351 and the second mounting portion 352 clamp and fix the marking member 330. Therefore, when the locking member 355 locks the first mounting portion 351 and the second mounting portion 352, the first mounting portion 351 and the second mounting portion 352 can stably fix the marking member 330. When the locking member 355 releases the first mounting portion 351 and the second mounting portion 352, the marking member 330 can be removed from the workpiece 20 and replaced.
[0075] like Figure 10 Furthermore, the first mounting portion 351 has a first adapter groove 353, and the second mounting portion 352 has a second adapter groove 354. The first adapter groove 353 and the second adapter groove 354 communicate and combine to form an adapter cavity, which is adapted to the shape of the marker 330 to stably fix the marker 330. As one example, the marker 330 has an approximately cylindrical shape, and the first adapter groove 353 and the second adapter groove 354 can be constructed as semi-circular grooves.
[0076] In one embodiment, the locking member 355 may be configured as a threaded fastener (such as a screw or bolt) to lock the first mounting portion 351 and the second mounting portion 352 by thread engagement.
[0077] Please see Figure 11 Combined Figure 2 and Figure 3 In one embodiment, the dispensing assembly 400 is located between the marking assembly 300 and the placing assembly 500. The dispensing assembly 400 includes a third support 410 and a pickup 420. The third support 410 is mounted on the conveying assembly 100, and the pickup 420 is movably disposed on the third support 410 to transfer the workpiece 20 conveyed by the conveying assembly 100 to the second placing member 520.
[0078] Please continue reading. Figure 11In one embodiment, the material distribution assembly 400 further includes a crossbeam 430, a longitudinal beam 440, a first driver 450, a second driver 460, and a third driver 470. The crossbeam 430 is disposed on the third support 410. The first driver 450 is connected to the crossbeam 430 to drive the crossbeam 430 to move relative to the third support 410 along the first direction S1.
[0079] A crossbeam 430 extends along the second direction S2, a longitudinal beam 440 is disposed on the crossbeam 430, and a second driver 460 is connected to the longitudinal beam 440 to drive the longitudinal beam 440 to move relative to the crossbeam 430 along the second direction S2.
[0080] The longitudinal beam 440 extends along the third direction S3, the pickup 420 is movably disposed on the longitudinal beam 440 along the third direction S3, and the third actuator 470 is connected to the pickup 420 to drive the pickup 420 to move along the third direction S3.
[0081] The first direction S1, the second direction S2, and the third direction S3 intersect each other. The first placement component 510 and the second placement component 520 are arranged side by side along the first direction S1. The second direction S2 is parallel to the conveying direction of the workpiece 20. Along the second direction S2, the first placement component 510 is aligned with the conveying assembly 100, that is, the first placement component 510 is located on the downstream side XY of the conveying assembly 100, and the second placement component 520, which is arranged side by side with the first placement component 510, is also located in the downstream area of the conveying assembly 100. Therefore, the conveying assembly 100 can directly convey the workpiece 20 (e.g., the workpiece 20 judged to be good) to the first placement component 510. The pickup component 420 moves relative to the longitudinal beam 440 along the third direction S3, and can approach and move away from the conveying plane of the workpiece 20 in order to pick up the workpiece 20. Pick-up component 420 moves along the second direction S2 with the longitudinal beam 440. Therefore, after picking up workpiece 20, pick-up component 420 can transfer workpiece 20 from the conveying assembly 100 to the second placement component 520 in the downstream area of the conveying assembly 100 along the second direction S2. In addition, pick-up component 420 can also move along the first direction S1 with the longitudinal beam 440 and the crossbeam 430 to facilitate lateral movement and accurate alignment with the second placement component 520, placing workpiece 20 (e.g., workpiece 20 determined to be defective) in the second placement component 520.
[0082] like Figure 10 In one embodiment, the driver 320 can drive the marker 330 to move closer to and further away from the workpiece 20 along a third direction S3. The first clamping roller 121 and the second clamping roller 122 are arranged side-by-side along the third direction S3, and the third clamping roller 131 and the fourth clamping roller 132 are also arranged side-by-side along the third direction S3. The rotation axis of each clamping roller may be parallel to the first direction S1. The cutting assembly 600 can cut the film material 30 along the first direction S1.
[0083] In one embodiment, the first direction S1, the second direction S2, and the third direction S3 are perpendicular to each other.
[0084] In one embodiment, one end of the crossbeam 430 is disposed on the third bracket 410, and the other end may be disposed on the first bracket 310 to improve the positional stability of the crossbeam 430. Further, the first actuator 450 may be disposed on the first bracket 310.
[0085] Please continue reading. Figure 11 In one embodiment, the first placement component 510 and the second placement component 520 can be configured as a conveyor belt structure, so that both the first placement component 510 and the second placement component 520 can move the workpiece 20 to at least two different workstations. Taking the first placement component 510 as an example, the conveying component 100 can transfer the workpiece 20 to the first receiving position of the first placement component, and the first placement component 510 can move the workpiece 20 from the first receiving position to the first unloading position. Thus, when the number of workpieces 20 at the first receiving position reaches a set threshold, the first placement component 510 transports the workpieces 20 to the first unloading position, thereby reserving space at the first receiving position for the workpieces 20 transported by the conveying component 100. This arrangement facilitates flexible handling of the workpieces 20 placed at the first placement component 510. Similarly, the material distribution component 400 can place the workpiece 20 at the second receiving position, and the second placement component 520 can transport the workpiece 20 from the second receiving position to the second unloading position.
[0086] Please see Figure 2 and Figure 3 In one embodiment, the feeding and screening device 10 includes multiple feeding and screening lines 11 arranged side by side. Each feeding and screening line 11 has a conveying component 100, a coating component 200, a marking component 300, a distributing component 400, a placing component 500, and a cutting component 600 as described in various embodiments. That is, each feeding and screening line 11 can independently perform the coating process and the feeding and screening process of the workpiece 20 to improve efficiency. Of course, in some embodiments, the workpieces 20 on different feeding and screening lines 11 can share a support, using a shared first support 310, second support 150, and third support 410, etc., to simplify the overall structure.
[0087] Furthermore, multiple feeding screening lines 11 can be arranged side by side along the direction perpendicular to the conveying direction, that is, multiple feeding screening lines 11 can be arranged side by side along the first direction S1.
[0088] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
