[0002] In the production process of electronic components, it is necessary to package the electronic components. For example, after the production of surface mount resistors, surface mount capacitors or other electronic components, the electronic components need to undergo appearance inspection and packaging.
[0003] Currently, in related technologies, quality inspection is usually carried out manually, and qualified and unqualified products are sorted manually. After sorting, qualified electronic components are then packaged in tape and reel. This manual process is very inefficient. Summary of the Invention

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0024] The first aspect of this application provides a material packaging method applied to material packaging equipment. This application first describes the material packaging equipment. (Refer to...) Figure 1 , Figure 1This is a simplified structural diagram of a material packaging device according to an embodiment of this application. The material packaging device includes a vibrating transport module, a first imaging component, a first top-feeding module, a second top-feeding module, a tape conveyor track 200, a waste module 300, and a transfer module. The transfer module includes a drive component and a turntable 100. The drive component is a rotary motor. The edge of the turntable 100 has multiple notches 110 spaced circumferentially along its edge. The spacing between each notch 110 is equal, and the shape of the notches 110 is generally rectangular. The material can be surface-mount capacitors, surface-mount resistors, or other sheet-like materials. The tape conveyor track 200 and the waste module 300 are respectively located below the opposite sides of the turntable 100.
[0025] It is worth noting that the first imaging component includes a first imaging camera and a second imaging camera. The first imaging camera is located directly above the edge of the turntable 100, and the second imaging camera is located directly below it. The turntable 100 is located between the first and second imaging cameras. The first imaging camera is used to capture an image of the end face of the material on the notch 110 directly below it; the second imaging camera is used to capture an image of the bottom face of the material on the notch 110 directly below it.
[0026] It is worth noting that the tape conveyor track 200 is used to drive the tape 210 to move linearly along its length. The tape 210 has multiple receiving slots 211 spaced apart along its length to accommodate materials. The tape conveyor track 200 can be composed of a motor and a conveyor belt; this application embodiment does not limit the specific structure of the tape conveyor track 200. Furthermore, the tape conveyor track 200 is connected to a tape assembly module, which is used to close the caps of the tape 210 onto the tape 210 to complete the packaging of the material. This application does not limit the tape assembly module; those skilled in the art can use existing tape assembly modules.
[0027] It is worth noting that the vibration transport module includes a vibratory feeder 410, a second shooting assembly, an air blowing assembly, and a material transport track 420. The vibratory feeder 410 is used to drive the material to move along the side wall of the vibratory feeder 410 to the material transport track 420, and then transport it along the material transport track 420 to the notch 110; see reference. Figure 2 , Figure 2This is a simplified schematic diagram of a partial structure of the sidewall of the vibratory feeder 410 according to an embodiment of this application. An air-blowing assembly is disposed inside the vibratory feeder 410, and the air outlet of the air-blowing assembly is flush with the sidewall of the vibratory feeder 410. The second imaging assembly is a third imaging camera, which is disposed above the vibratory transport module, with its lens facing the sidewall of the vibratory feeder 410. The air-blowing assembly consists of an air pipe 411 and a blower. The air pipe 411 is placed inside the sidewall of the vibratory feeder 410, and the opening of the air pipe 411 is flush with the sidewall of the vibratory feeder 410, so that the air pipe 411 does not interfere with the movement of the material. The blower enables the air pipe 411 to blow gas out. When the air pipe 411 blows gas out, it can blow the material that has just moved to the opening of the air pipe 411 from the sidewall of the vibratory feeder 410 to the bottom of the vibratory feeder 410. It is worth noting that the material to be sorted is placed at the bottom of the vibratory feeder 410. When the vibratory feeder 410 is running, it drives the material to move along the side wall of the feeder 410 in a spiral path. During the movement, the material first passes the shooting point of the third camera, then passes through the opening of the air pipe 411, and then enters the material transport track 420. It is then transported through the material transport track 420 and fits precisely into the notch 110 of the turntable 100. It is worth noting that the width of the side wall of the vibratory feeder 410 is slightly greater than the length of the material, so that only one piece of material can pass through the opening of the air pipe 411 at any given time.
[0028] It is worth noting that the waste module 300 is a waste collection box, which is located below the edge of the turntable 100. The second top-feeding module can push non-conforming materials from the notch 110 directly above the waste collection box into the waste collection box, thereby completing the collection of non-conforming products.
[0029] It is worth noting that the first top material module includes a first drive cylinder and a first push rod. The first drive cylinder is used to drive the first push rod to perform lifting and lowering movements so that the first push rod pushes the material in the notch 110 located directly below the first top material module onto the receiving groove 211 of the tape 210.
[0030] It is worth noting that the second top material module includes a second drive cylinder and a second push rod. The second drive cylinder is used to drive the second push rod to perform lifting and lowering movements so that the second push rod pushes the non-qualified material from the notch 110 directly above the waste collection box into the waste collection box.
[0031] Reference Figure 3 , Figure 3 This is a schematic flowchart illustrating the steps of a material packaging method according to an embodiment of this application. The material packaging method of this application is applied to the aforementioned material packaging equipment, including but not limited to steps S110 to S150.
[0032] Step S110: Control the drive component to periodically drive the turntable to rotate, and control the vibration transport module to transport each material to the different gaps on the turntable in sequence. Step S120: Control the first imaging component to capture images of the material that has moved to the position opposite the first imaging component, obtain the first image to be detected, and record the first shooting time of the first image to be detected; Step S130: Detect the material in the first image to be detected based on the first image to be detected, and obtain the detection result; Step S140: When the detection result indicates that the material in the first image to be detected is qualified, the first material feeding module is controlled to push the material in the first image to be detected from the notch into the tape conveyor track based on the first shooting time. In step S150, if the detection result indicates that the material in the first image to be detected is unqualified, the second material feeding module is controlled to push the material in the first image to be detected from the gap into the waste material module based on the first shooting time.
[0033] It is worth noting that, through steps S130 to S150, relying on the first image to be detected and the first shooting time, the two first and second top-loading modules can be driven to complete the separation of qualified and unqualified materials, without the need for additional multiple detection sensors or complex material tracking systems. The equipment has a compact structure and clear control logic, reducing hardware costs and the implementation difficulty of the control system.
[0034] The material packaging method according to the embodiments of this application has at least the following beneficial effects: The material packaging method of the embodiments of this application is executed by a material packaging equipment. During execution, the drive component is first controlled to periodically drive the turntable to rotate. During the rotation of the turntable, the vibration transport module is controlled to transport the material sequentially to each notch on the turntable. Then, the first imaging component takes a picture of the material moving to the position opposite the first imaging component to obtain a first image to be detected and a first imaging time. The material is detected by the first image to be detected. If the detection result indicates that the material in the first image to be detected is qualified, the first top-feeding module is controlled based on the first imaging time to push the qualified material from the notch into the tape conveyor track, so that the qualified material falls into the packaging tape on the tape conveyor track to complete the packaging of the material. If the detection result indicates that the material in the first image to be detected is unqualified, the second top-feeding module is controlled based on the first imaging time to push the unqualified material into the waste module. Thus, the method of the embodiments of this application realizes automated material packaging, while realizing the detection of the appearance quality of the material and the sorting of qualified and unqualified materials, thereby improving the material packaging efficiency and production efficiency. It achieves efficient separation of qualified and unqualified materials, prevents unqualified materials from being mixed into the finished product material belt, significantly improves the qualification rate of material packaging, reduces material waste and subsequent rework costs, greatly improves the overall efficiency and automation level of material packaging, adapts to the continuous packaging needs of large batches of materials, reduces human error in the production process, and improves production stability and product consistency.
[0035] In some embodiments, step S110 may include, but is not limited to, steps S111 to S113.
[0036] Step S111: Obtain the preset speed, preset cycle interval, and the first number of gaps in the turntable; Step S112: Determine the target angle based on the first quantity; Step S113: Based on a preset periodic interval, periodically control the drive component to drive the turntable to rotate at a preset speed to the target angle.
[0037] It is worth noting that the preset cycle interval refers to the duration of the turntable's pause. Those skilled in the art can set the preset speed, preset cycle interval, and first quantity according to actual conditions; this application does not impose specific limitations on this. In step S112, the target angle is equal to 360 / first quantity. For example, if the first quantity is 3, then the target angle is 360 / 3 = 120 degrees. Through steps S111 to S113, the turntable rotates at the target angle each time, and pauses once after each rotation, with the pause duration equal to the preset cycle interval. Through debugging, when the turntable pauses, one notch on the turntable precisely aligns with the end of the material transport track of the vibrating transport module, allowing the material transport track to transport the material into the notch. After pausing for the preset cycle interval, the drive unit starts, causing the turntable to rotate the target angle and stop again, at which point the next notch precisely aligns with the end of the material transport track. Thus, the automated transport of multiple materials sequentially to their respective notches is achieved.
[0038] In some embodiments, step S140 may include, but is not limited to, the following steps: Step S141: Obtain the first included angle, which represents the angle by which the turntable rotates to move the material from a position opposite to the first shooting component to directly below the first top material module; It is worth noting that the first included angle is determined based on the position of the first shooting camera and the position of the first top material module. The angle that the turntable needs to rotate during the process of the material moving from directly below the first shooting camera to directly below the first top material module is the first included angle.
[0039] Step S142: Calculate the duration of a single rotation based on the target angle and the preset speed; It is worth noting that the duration of a single rotation = target angle / preset speed.
[0040] Step S143: Determine the first number of rotations based on the first included angle and the target angle; It is worth noting that the first number of rotations = the first included angle / the target angle.
[0041] Step S144: Calculate the first duration based on the first number of rotations, the duration of a single rotation, and the preset period interval; Step S145: Based on the first duration and the first shooting time, obtain the first target time; It is worth noting that the first target time is calculated using the first formula, which is: ; Where T1 is the first target time, T0 is the first shooting time, k is the first number of rotations, Tr is the duration of a single rotation, Tp is the preset period interval, and k(Tr+Tp) is the first duration.
[0042] Step S146: At the first target moment, control the first material feeding module to push the material in the first image to be detected from the notch into the tape conveyor track.
[0043] This embodiment of the application, through steps S141 to S146, obtains a first included angle, calculates the duration of a single rotation by combining the target angle and a preset speed, and then determines the first number of rotations using the first included angle and the target angle. Finally, it accurately calculates the first duration from the shooting moment to the material ejection moment, thereby determining the first target moment and controlling the action of the first material ejection module. This achieves precise linkage between shooting detection and material ejection action, ensuring that the first material ejection module is triggered when qualified material moves directly below it. This allows the material to be accurately and smoothly ejected into the conveyor belt track, preventing material from deviating from the track, getting stuck in equipment gaps, or colliding with other components and causing damage due to premature or delayed ejection. This effectively improves the smoothness and safety of material transmission. It ensures that qualified material can accurately enter the corresponding position on the conveyor belt, improving the appearance quality and consistency of the packaged product, and reducing material loss and packaging scrap rate.
[0044] In some embodiments, step S150 may include, but is not limited to, the following steps: Step S151, obtain the second included angle; the second included angle represents the angle at which the turntable rotates to move the material relative to the first shooting component to the position directly below the second top material module; It is worth noting that the second included angle is determined based on the position of the first shooting camera and the position of the second top material module. The angle that the turntable needs to rotate during the process of moving from directly below the first shooting camera to directly below the second top material module is the second included angle.
[0045] Step S152: Determine the second number of rotations based on the second included angle and the target angle; It is worth noting that the second number of rotations = the second included angle / the target angle.
[0046] Step S153: Calculate the second duration based on the second number of rotations, the duration of a single rotation, and the preset period interval; Step S154: Based on the second duration and the first shooting time, obtain the second target time; It is worth noting that the second target time is calculated using the second formula, which is: ; Where T2 is the second target time, T0 is the first shooting time; n is the second number of rotations; Tr is the duration of a single rotation; Tp is the preset period interval; and n(Tr+Tp) is the second duration.
[0047] In step S155, at the second target time, the second material feeding module is controlled to push the material in the first image to be detected from the notch into the waste material module.
[0048] In this embodiment, through steps S151 to S155, the second included angle is obtained, and the duration of a single rotation is calculated by combining the target angle and the preset speed. Then, the second number of rotations is determined by the second included angle and the target angle. Finally, the second duration from the shooting time to the waste module is accurately calculated, thereby determining the second target time and controlling the action of the second top material module. This ensures that when the non-conforming material moves to the area directly below the second top material module, the second top material module is triggered in time, causing the non-conforming material to fall into the waste module, preventing the non-conforming material from being packaged, and reducing the packaging waste rate.
[0049] In some embodiments, the material packaging method of this application embodiment may further include the following steps after step S140: Each time the first feeding module completes a feeding operation, it controls the tape conveyor track to drive the tape to move a preset distance along the length direction so that the next receiving slot in the tape is located directly below the first feeding module.
[0050] It is worth noting that the ejection operation refers to the first ejection module ejecting qualified material from the first image to be inspected through the notch into the tape conveyor track, so that the qualified material falls into the receiving slot of the tape. Each time the first ejection module completes an ejection operation, it means that the current receiving slot has received qualified material. Therefore, the tape conveyor track is controlled to drive the tape to move a preset distance along its length so that the next receiving slot in the tape is located directly below the first ejection module, so that the next qualified material can fall into the receiving slot.
[0051] In some embodiments, the first image to be detected includes a front image and a back image, wherein the front image is captured by a first camera and the back image is captured by a second camera. Step S130 may include, but is not limited to, steps S131 to S132. Step S131: Perform grayscale conversion on the front image and the back image respectively to obtain a front grayscale image and a back grayscale image; Step S132: Calculate the first structural similarity index between the frontal grayscale image and the preset frontal standard grayscale image; Step S133: Calculate the second structural similarity index between the back grayscale image and the preset back standard grayscale image; Step S134: If the first structural similarity index is greater than or equal to the preset index threshold and the second structural similarity index is greater than or equal to the preset index threshold, the detection result is determined to be that the material in the first image to be detected is qualified. In step S135, if the first structural similarity index is less than the preset index threshold or the second structural similarity index is less than the preset index threshold, the detection result is determined to be that the material in the first image to be detected is unqualified.
[0052] It is worth noting that the Structural Similarity Index (SSIM) is a metric used to measure the similarity between two images. It is based on the human visual system's perception of image structural information and comprehensively evaluates image quality from three dimensions: brightness, contrast, and structure. The SSIM value ranges from -1 to 1; a value closer to 1 indicates greater structural similarity between the two images. When two images are completely identical, the SSIM value is 1. Those skilled in the art can set preset index thresholds according to actual circumstances; this application does not impose any limitations on this.
[0053] This embodiment of the application, through steps S131 to S135, realizes the appearance quality inspection of the front and back of the material, and realizes the appearance quality inspection of the material by using only one device, namely the material packaging equipment, to simultaneously realize the two processes of quality inspection and material packaging, thereby improving the production efficiency of the material.
[0054] In some embodiments, the control vibration transport module in step S110 transports each material sequentially to each notch of the turntable, which may include steps S210 to S240.
[0055] Step S210: Control the vibratory feeder to drive the material to move along the side wall of the vibratory feeder to the material transport track, and then move along the material transport track to the notch. Step S220: During the operation of the vibratory feeder, the material located on the side wall of the vibratory feeder is photographed by the second imaging component to obtain a second image to be detected; Step S230: Detection is performed based on the second image to be detected; In step S240, when it is detected that the side of the material in the second image to be detected facing away from the vibrating plate sidewall is a preset reverse side, the blowing assembly is controlled to blow the material in the second image to be detected off the sidewall.
[0056] It is worth noting that in some embodiments, the front of the material is marked, while the back is unmarked. For example, if the material is a surface mount resistor or other electronic component, when packaging the surface mount resistors, it is required that all the surface mount resistors on the tape are facing the same direction, generally with the front of each surface mount resistor facing upwards. During the operation of the vibratory feeder, the material adheres to the side wall of the vibratory feeder, and the material transport track is a horizontal straight track. During the movement from the vibratory feeder to the material transport track, the side of the material facing away from the side wall of the vibratory feeder faces upwards, and the orientation of the material does not change throughout the entire transport process.
[0057] It is worth noting that the side of the material with the markings is designated as the preset front side, while the side without markings is also designated as the preset front side. Therefore, through steps S210 to S240, the material with the side facing away from the vibrating plate sidewall (which is the preset back side) is blown off, ensuring that each piece of material transported to the material transport track has its preset front side facing up. This guarantees that when the material is packaged on the tape, the orientation of all materials on the tape is the same, ensuring the consistency of the material on the tape.
[0058] In some embodiments, when the material moves along the side wall of the vibratory feeder, the material's moving speed is fixed at a preset moving speed, and the time required for the material to move from the position relative to the third camera to the opening of the air tube is fixed at a third time. Therefore, in step S220, the time when the second image to be detected is captured is recorded as the second capture time. In step S240, if it is detected that the side of the material in the second image to be detected facing away from the vibratory feeder side wall is the preset reverse side, then based on the third time and the second capture time, a third target time is obtained, which is equal to the second capture time plus the third time. At the third target time, the air blowing component is controlled to blow air, so that the material with the side facing away from the vibratory feeder side wall being the preset reverse side falls to the bottom of the vibratory feeder. It should be noted that the algorithm for detecting the second image to be detected in step S230 can directly adopt algorithms in the prior art. It can be determined whether the side of the material facing away from the vibratory feeder side wall is the preset reverse side by identifying whether the side of the material in the image being captured has a mark. Those skilled in the art can select an algorithm according to the actual situation, and this application does not make specific limitations in this regard.

Figure 4 , Figure 4 This is a functional unit diagram of a material packaging device according to an embodiment of this application. The material packaging device includes: The transport control unit 310 is used to control the drive component to periodically drive the turntable to rotate, and to control the vibration transport module to transport each material to each gap of the turntable in sequence. The shooting control unit 320 is used to control the first shooting component to shoot the material that has moved to the position opposite to the first shooting component, to obtain the first image to be detected and to record the first shooting time of the first image to be detected; The detection unit 330 is used to detect the material in the first image to be detected based on the first image to be detected, and to obtain the detection result; The first material feeding control unit 340 is used to control the first material feeding module to push the material in the first image to be detected from the notch into the tape conveyor track based on the first shooting time when the detection result indicates that the material in the first image to be detected is qualified. The second top material control unit 350 is used to control the second top material module to push the material in the first image to be detected from the gap into the waste material module based on the first shooting time when the detection result indicates that the material in the first image to be detected is unqualified.
[0060] The material packaging device of this application embodiment is used to execute the material packaging method of the first aspect embodiment. In executing the method, a drive component is first controlled to periodically drive a turntable to rotate. During the turntable rotation, a vibration transport module is controlled to sequentially transport materials to various notches on the turntable. Then, a first imaging component captures images of the materials moving to the position opposite the first imaging component to obtain a first image to be detected and a first imaging time. The materials are detected using the first image to be detected. If the detection result indicates that the materials in the first image to be detected are qualified, a first ejector module is controlled based on the first imaging time to eject the qualified materials from the notches into the tape conveyor track, so that the qualified materials fall onto the packaging tape on the tape conveyor track, thus completing the material packaging. If the detection result indicates that the materials in the first image to be detected are unqualified, a second ejector module is controlled based on the first imaging time to eject the unqualified materials into the waste module. Thus, the method of this application embodiment achieves automated material packaging while simultaneously detecting the appearance quality of the materials and sorting qualified and unqualified materials, improving material packaging efficiency and production efficiency.
