With the continuous development of the manufacturing industry, the requirements for workpiece defect detection and subsequent processing are increasing. Currently, workpiece defect detection technology has made significant progress, enabling the efficient identification of various defects in workpieces.

[0003] Most existing recycling devices can only collect simple workpieces and cannot accurately classify them according to complex defect types. This often results in some workpieces with minor defects that can be reused after rework being classified as waste products, leading to a decrease in the actual utilization rate of workpieces and an increase in costs.

[0006] The transmission mechanism includes a material conveyor belt, on which multiple transmission chambers are spaced apart along its conveying direction. The gripping device grips multiple pieces of the workpiece that have completed inspection and places them one by one into the multiple transmission chambers.

[0007] The recycling device includes a blowing assembly and a recycling mechanism. Along direction A, the blowing assembly and the recycling mechanism are respectively disposed on both sides of the material conveyor belt. The blowing assembly is communicatively connected to the detection device.

[0008] The multiple nozzles in the blowing assembly are spaced apart on one side of the material conveyor belt along the conveying direction of the material conveyor belt, and the multiple nozzles are all connected to external blowing equipment. The recycling mechanism includes multiple recycling boxes with openings at the top. The multiple recycling boxes and the multiple nozzles are arranged one-to-one on the other side of the material conveyor belt. The nozzles are selectively opened to blow the corresponding workpiece to the corresponding recycling box.

[0009] As a further technical solution, along direction A, a first support plate and a second support plate are respectively provided on both sides of the material conveyor belt;

[0010] The first support plate is provided with a plurality of spray channels at intervals along the conveying direction of the material conveyor belt, and a plurality of nozzles are inserted into the plurality of spray channels in a corresponding manner. The second support plate is provided with a plurality of recycling channels in a corresponding manner to the plurality of spray channels.

[0011] As a further technical solution, a plurality of guide members are provided on the side of the second support plate away from the material conveyor belt. The plurality of guide members are provided one-to-one with the plurality of recycling channels, and the side of the plurality of guide members away from the second support plate extends into the corresponding recycling bin. Each guide member is provided with a guide channel that communicates with the corresponding recycling channel.

[0012] As a further technical solution, the recycling mechanism also includes multiple enclosure components, each enclosure component including a baffle, which is disposed on the side of the multiple recycling bins away from the material conveyor belt.

[0013] As a further technical solution, the enclosure assembly also includes a base and a top plate, with the multiple recycling bins being detachably disposed in the multiple storage cavities of the base, and the top plate being disposed on top of the multiple recycling bins.

[0014] As a further technical solution, the enclosure assembly also includes multiple buffer plates, the first ends of the multiple buffer plates are disposed on the lower end surface of the top plate in a one-to-one correspondence with the multiple recycling bins, and the second ends of the multiple buffer plates extend in a direction away from the top plate.

[0015] As a further technical solution, the baffle, the top plate, and the plurality of buffer plates are all configured as flexible plates;

[0016] Alternatively, flexible buffer sections are provided on the side of the baffle near the material conveyor belt, the lower end face of the top plate, and the side of the plurality of buffer plates near the material conveyor belt.

[0017] As a further technical solution, the recycling mechanism also includes a preparatory box, which is located at the front end of the material conveyor belt along the conveying direction of the material conveyor belt.

[0018] As a further technical solution, the transmission mechanism also includes a mounting bracket, a drive motor, a driving gear, and a driven gear;

[0019] Along the conveying direction of the material conveyor belt, the driving toothed wheel and the driven toothed wheel are respectively rotatably disposed at both ends of the mounting frame.

[0021] The technical advantages of the above-mentioned product screening equipment are as follows:

[0022] Because the blowing assembly is communicatively connected to the detection device, and multiple nozzles are connected to external blowing equipment, multiple recycling bins are correspondingly positioned on the other side of the material conveyor belt, with multiple transmission chambers spaced apart along its conveying direction. Therefore, after the detection device completes defect detection on multiple workpieces, it marks and classifies them according to the degree of defect and synchronizes the classification information to the blowing assembly. Then, the gripping device grips the inspected workpieces and places them into the corresponding transmission chambers. Subsequently, as the material conveyor belt rotates, the workpieces are transported between the blowing assembly and the recycling mechanism. The blowing assembly then selectively opens the corresponding nozzles based on the received classification information of the workpieces, blowing the workpieces into the corresponding recycling bins under the action of the blowing force. This completes the classification and recycling of the inspected workpieces, thereby improving the actual utilization rate of the workpieces and reducing costs. Attached Figure Description

[0032] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0033] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0034] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0035] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0036] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0037] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0038] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0039] Combination Figures 1 to 5As shown, the product screening equipment provided in this embodiment is used to recycle workpieces that have undergone defect detection by the testing device. The workpieces that have completed the detection are divided into several categories according to the degree of defect. This product screening equipment can realize the classified recycling of detected workpieces, thereby improving the actual utilization rate of workpieces and reducing costs. The product screening equipment includes a conveying mechanism 100 and a recycling device 200. The conveying mechanism 100 includes a material conveyor belt 111, on which multiple transmission chambers 1110 are spaced apart along the conveying direction. A gripping device grips multiple workpieces that have completed testing and places them one by one into the multiple transmission chambers 1110. The recycling device 200 includes a blowing assembly 210 and a recycling mechanism. Along direction A, the blowing assembly 210 and the recycling mechanism are respectively arranged on both sides of the material conveyor belt 111. The blowing assembly 210 is communicatively connected to the testing device. Multiple nozzles 211 in the blowing assembly 210 are spaced apart on one side of the material conveyor belt 111 along the conveying direction, and all of the nozzles 211 are connected to an external blowing device. The recycling mechanism includes multiple recycling boxes 221 with openings at the top. The multiple recycling boxes 221 and the multiple nozzles 211 are arranged one by one on the other side of the material conveyor belt 111. The nozzles 211 are selectively opened to blow the corresponding workpieces into the corresponding recycling boxes 221.

[0040] Since the blowing assembly 210 is communicatively connected to the detection device, and multiple nozzles 211 are connected to external blowing equipment, multiple recycling bins 221 are correspondingly arranged on the other side of the material conveyor belt 111, and multiple transmission chambers 1110 are spaced apart along the conveying direction on the material conveyor belt 111. Therefore, after the detection device completes defect detection on multiple workpieces, it marks and classifies the multiple workpieces according to the degree of defect and synchronizes the classification information to the blowing assembly 210; then, the gripping device grips the multiple workpieces that have completed the detection and places them one by one into the multiple transmission chambers 1110; then, as the material conveyor belt 111 operates, the multiple workpieces are transported between the blowing assembly 210 and the recycling mechanism. Then, the blowing assembly 210 selectively opens the corresponding nozzles 211 according to the classification information of the multiple workpieces received, and under the action of the blowing force, blows the multiple workpieces into the corresponding recycling bins 221, thereby completing the classification and recycling of the detected workpieces, thereby improving the actual utilization rate of the workpieces and reducing costs.

[0041] In this embodiment, the blowing assembly 210 includes a mounting member 212 and a plurality of nozzles 211. The mounting member 212 is disposed on one side of the material conveyor belt 111 and extends along the conveying direction of the material conveyor belt 111. The plurality of nozzles 211 are spaced apart on the mounting member 212 along the conveying direction of the material conveyor belt 111, and all the nozzles 211 are connected to an external blowing device. The mounting member 212 and the external blowing device are configured according to the prior art, and will not be described in detail here.

[0042] Specifically, for example, along the conveying direction of the material conveyor belt 111, multiple nozzles 211 are sequentially configured as defect-free blowing nozzles, returnable blowing nozzles, and waste blowing nozzles; correspondingly, multiple recycling bins 221 are configured opposite to the multiple nozzles 211 as defect-free bins, returnable bins, and waste bins; if the current workpiece is a defect-free part, then as the material conveyor belt 111 rotates, when the transmission cavity 1110 containing the defect-free part is opposite to the defect-free blowing nozzle, the defect-free blowing nozzle opens, blowing the defect-free part in the transmission cavity 1110 into the defect-free bin; if the current workpiece is a returnable part, then as the material conveyor belt 111 rotates, when the transmission cavity 1110 containing the defect-free part is opposite to the defect-free blowing nozzle, the defect-free blowing nozzle opens, blowing the defect-free part in the transmission cavity 1110 into the defect-free bin; if the current workpiece is a returnable part, then as the material conveyor belt 111 rotates, the material conveyor belt 111 rotates, and ... contains the defect-free part, the material conveyor belt 111 rotates, and when the transmission cavity 1110 is opposite to the defect-free blowing nozzle, the material conveyor belt 111 rotates, and when the transmission cavity 1110 is opposite to the defect-free blowing nozzle, the material conveyor belt 111 rotates, and when the transmission cavity 111 is opposite to the defect-free blowing nozzle, the material conveyor belt 111 rotates, and when the transmission As the material conveyor belt 111 operates, when the transmission cavity 1110 containing returnable parts is aligned with the defect-free nozzle, the defect-free nozzle remains closed until it aligns with the returnable nozzle, at which point the returnable nozzle opens, blowing the returnable parts from the transmission cavity 1110 into the returnable container. If the current workpiece is a waste part, both the defect-free and returnable nozzles remain closed as the material conveyor belt 111 operates until the transmission cavity 1110 containing waste parts aligns with the waste nozzle, at which point the waste nozzle opens, blowing the waste parts from the transmission cavity 1110 into the waste container. Thus, through the coordinated operation of the blowing assembly 210 and the recycling mechanism, which are communicatively connected to the detection device, the classified recycling of detected workpieces is achieved.

[0043] The detection and gripping devices are not the focus of this solution and can be set up with reference to existing technologies, so they will not be described in detail here.

[0044] During the process of the nozzle 211 blowing the corresponding workpiece to the corresponding recycling bin 221, in order to prevent the workpiece's movement path from deviating when it is blown from the transmission chamber 1110 to the corresponding recycling bin 221, in this embodiment, a first support plate 112 and a second support plate 113 are respectively provided on both sides of the material conveyor belt 111 along direction A; the first support plate 112 is provided with multiple blowing channels at intervals along the conveying direction of the material conveyor belt 111, and multiple nozzles 211 are inserted into the multiple blowing channels one-to-one; the second support plate 113 is provided with multiple recycling channels one-to-one with the multiple blowing channels. Furthermore, the one-to-one insertion of multiple nozzles 211 into the multiple blowing channels can limit the relative position between the multiple nozzles 211 and the multiple recycling channels, thereby further improving the blowing effect and the workpiece recycling effect.

[0045] Combination Figure 3As shown, during the process of the nozzle 211 blowing the corresponding workpiece into the corresponding recycling box 221, after the workpiece is blown out of the corresponding recycling channel, in order to prevent the workpiece from falling directly to the ground under its own weight instead of being blown into the corresponding recycling box 221, in this embodiment, multiple guides 114 are provided on the side of the second support plate 113 away from the material conveyor belt 111. The multiple guides 114 are provided one-to-one with multiple recycling channels, and the side of the multiple guides 114 away from the second support plate 113 extends into the corresponding recycling box 221. Each guide 114 is provided with a guide channel 1141 that communicates with the corresponding recycling channel. The first end of the guide channel 1141 is connected to the corresponding recycling channel, and the other end is connected to the corresponding recycling box 221. After the workpiece is blown out of the corresponding recycling channel, it directly enters the corresponding guide channel 1141 and is finally recycled into the corresponding buffer channel, thereby further improving the actual utilization rate of the workpiece.

[0046] After the workpiece enters the corresponding recycling bin 221 from the guide channel 1141, in order to prevent the workpiece from being directly blown to the side of the corresponding recycling bin 221 away from the guide 114 under the action of the blowing force, in this embodiment, the recycling mechanism also includes multiple enclosure components 222. The enclosure components 222 include baffles 2221. The baffles 2221 are disposed on the side of the multiple recycling bins 221 away from the material conveyor belt 111. The baffles 2221 play a role in blocking the workpiece blown out from the guide channel 1141.

[0047] Furthermore, the enclosure assembly 222 also includes a base 2222 and a top plate 2223. Multiple recycling bins 221 are detachably installed in multiple storage cavities of the base 2222, and the top plate 2223 is installed on top of the multiple recycling bins 221.

[0048] In this embodiment, the base 2222 is a shell with an opening at the top, and the side of the base 2222 away from the guide member 114 does not have a sidewall. Multiple partitions 2225 are evenly spaced within the shell along direction A to divide the shell into multiple storage chambers. Multiple recycling bins 221 are detachably installed in the multiple storage chambers. When the number of workpieces in a recycling bin 221 reaches a certain amount, the corresponding recycling bin 221 is removed, and after processing all the workpieces in the recycling bin 221, it is placed back into the corresponding storage chamber. By setting the top plate 2223, the situation where workpieces fall out of the recycling bin 221 after entering it from the guide channel 1141 is further prevented. Furthermore, in this embodiment, the baffle 2221 is connected to the side of the top plate 2223 away from the material conveyor belt 170.

[0049] Since multiple recycling bins 221 are detachably installed in multiple storage cavities in a one-to-one correspondence, even if baffles 2221 are provided, there is a gap between the lower end of the baffles 2221 and the upper end of each recycling bin 221. In order to prevent the workpiece from being blown out of the corresponding recycling bin 221 through the gap between the baffles 2221 and the recycling bin 221, in this embodiment, the enclosure assembly 222 also includes multiple buffer plates 2224. The first end of the multiple buffer plates 2224 is provided on the lower end surface of the top plate 2223 in a one-to-one correspondence with the multiple recycling bins 221, and the second end of the multiple buffer plates 2224 extends in a direction away from the top plate 2223.

[0050] During the process of the nozzle 211 blowing the corresponding workpiece into the corresponding recycling bin 221, under the action of the blowing force, the workpiece may be blown into the baffle 2221, the top plate 2223, or the corresponding buffer plate 2224, causing the workpiece to be sprayed with the baffle 2221, the top plate 2223, or the corresponding buffer plate 2224, resulting in damage to the workpiece in the recycling bin 221 and reducing the final yield of the workpiece. In order to reduce the probability of the above situation, in this embodiment, the baffle 2221, the top plate 2223, and the multiple buffer plates 2224 are all set as flexible plates; or, flexible buffer parts are provided on the side of the baffle 2221 near the material conveyor belt 111, the lower end face of the top plate 2223, and the side of the multiple buffer plates 2224 near the material conveyor belt 111. The flexible plates or flexible buffer parts can be adapted to rubber parts, silicone parts, cotton cloth, plastic foam, etc., according to actual needs, and are not specifically limited here.

[0051] Preferably, the recycling mechanism further includes a preparatory box 223, which is located at the front end of the material conveyor belt 111 along the conveying direction of the material conveyor belt 111. During the sorting and recycling process of workpieces, there may be cases where workpieces in the transmission chamber 1110 are not blown into the recycling box 221 during the process of being conveyed from the rear end to the front end of the material conveyor belt 111. By setting the preparatory box 223 at the front end of the material conveyor belt 111, workpieces in the above situation can be directly conveyed into the preparatory box 223 instead of falling to the ground and being wasted. The workpieces collected in the preparatory box 223 are subsequently recycled and processed in a unified manner to further improve the actual utilization rate of the workpieces.

[0052] Preferably, the transmission mechanism 100 further includes a mounting frame 120, a drive motor 130, a driving toothed wheel 140, and a driven toothed wheel 150; along the conveying direction of the material conveyor belt 111, the driving toothed wheel 140 and the driven toothed wheel 150 are respectively rotatably disposed at both ends of the mounting frame 120, and the material conveyor belt 111 is connected to both the driving toothed wheel 140 and the driven toothed wheel 150 through transmission teeth, the drive motor 130 is disposed on the mounting frame 120, and the output shaft of the drive motor 130 is connected to the driving toothed wheel 140.

[0053] In this embodiment, two connecting side plates are arranged relatively parallel and spaced apart along direction A on the mounting frame 120. Along the conveying direction of the material conveyor belt 111, the two ends of the drive shaft on the drive toothed wheel 140 are rotatably connected to the first ends of the two connecting side plates respectively. The first end of the drive shaft is provided with a first transmission toothed wheel, and the output shaft of the drive motor 130 is provided with a second transmission toothed wheel. The second transmission toothed wheel and the first transmission toothed wheel are connected by a conveyor belt with transmission teeth. The two ends of the driven shaft on the driven toothed wheel 150 are rotatably connected to the second ends of the two connecting side plates respectively. The material conveyor belt 111 is connected to both the drive toothed wheel 140 and the driven toothed wheel 150 by transmission teeth. Its operating principle is as follows: the drive motor 130 rotates, driving the second transmission gear wheel to rotate. The second transmission gear wheel drives the first transmission gear wheel to rotate via a conveyor belt with transmission teeth, thereby driving the drive gear wheel 140 to rotate. With the cooperation of the material conveyor belt 111 with transmission teeth, the drive gear wheel 140 and the driven gear wheel 150 rotate synchronously, and the material conveyor belt 111 rotates to transport the workpiece. The specific structure and working principle of the drive motor 130 refer to the existing technology and will not be repeated here.

[0054] Furthermore, the transmission mechanism 100 also includes an adjusting bolt 160, which is screwed to the driven shaft on the driven gear 150. Tightening the adjusting bolt 160 adjusts the distance between the driving gear 140 and the driven gear 150.

[0055] To prevent the material conveyor belt 111 from stretching due to fatigue after long-term operation of the transmission mechanism 100, thus avoiding unsatisfactory workpiece transmission performance, in conjunction with... Figure 1 and Figure 2 As shown, in this embodiment, two adjusting bolts 160 are provided. Specifically, the second ends of both connecting side plates are provided with adjusting elongated holes 121, which extend along the conveying direction of the material conveyor belt 111. The two ends of the driven shaft are respectively inserted into the two adjusting elongated holes 121, and both ends of the driven shaft are provided with threaded holes. The end faces of the second ends of both connecting side plates are provided with adjusting holes (not shown in the figure) that communicate with the corresponding adjusting elongated holes 121. The two adjusting bolts 160 are inserted into the corresponding adjusting holes and threadedly connected to the corresponding threaded holes. When it is necessary to adjust the distance between the driving gear 140 and the driven gear 150, the two adjusting bolts 160 can be turned clockwise or counterclockwise simultaneously.

[0056] In this embodiment, the number of nozzles 211, recycling bins 221, and transmission chambers 1110 on the material conveyor belt 111 is not specifically limited.

[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
