[0002] In the mobile phone manufacturing industry, spring-loaded components (such as connector springs and spring contacts) are key electronic components, and their dimensional accuracy, surface features, and assembly quality directly affect product performance. Traditional testing and packaging processes have the following problems:

[0003] Manual inspection is inefficient: It relies on manual visual inspection of the height of the spring, the gold point and the cut edge, which is slow, easy to get tired, and has the risk of missing the inspection; it is not accurate enough: the manual measurement of the cut edge size has a large error and it is difficult to meet the micron-level accuracy requirements.

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0046] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model. Example

[0047] See appendix Figure 1 As shown, an automatic inspection and packaging device includes a workbench 1, a feeding module 2 for sorting and transferring spring parts, a vision inspection module 3 for detecting the spring height, presence of electroplated gold points, cut size, and orientation of small spring parts, a pulling module 5 for pulling a carrier belt 4, a carrier belt conveying module 6 for feeding and winding the carrier belt 4, a heat-sealing packaging module 8 for heat-sealing the carrier belt cover film 7 with the carrier belt 4, a cover film conveying module 9 for conveying the carrier belt cover film 7, and a control system (not shown) electrically connected to and controlling the feeding module 2, vision inspection module 3, pulling module 5, carrier belt conveying module 6, heat-sealing packaging module 8, and cover film conveying module 9.

[0048] The workbench 1 can be a horizontally arranged flat plate structure. A frame 11 is bolted to the lower end of the workbench 1. The frame 11 is made of high-strength square tube frame, and shock-absorbing feet 12 are installed at the bottom of the frame 11 to ensure the stability of the equipment operation. An open working cavity 13 is provided at the front of the frame 11 to facilitate the installation of the carrier belt feeding assembly 62.

[0049] See Figure 2 As shown, the feeding module 2 includes a flexible feeding component and a suction robot 21 set on the workbench 1. The flexible feeding component includes a feeder 22 fixedly installed on the upper surface of the workbench 1 and a feeding tray 23 set at the outlet of the feeder 22. Multiple voice coil motors 24 are set under the feeding tray 23, and the voice coil motors 24 can drive the feeding tray 23 to vibrate.

[0050] Specifically, the setup and structure of the robotic arm 21, the feeder 22, the feed tray 23, and the voice coil motor 24 are all existing technologies. That is, the spring parts automatically fall from the feeder 22 through its outlet into the feed tray 23, and the four voice coil motors 24 can shake and flip the spring parts in the feed tray 23.

[0051] The suction robot 21 can be an existing Delta parallel robot. The suction robot 21 is mounted on the robot housing 211. A vacuum nozzle 212 is installed at the end of the suction robot 21. The diameter of the vacuum nozzle 212 is adapted to the size of the spring part. In order to realize the rotation of the vacuum nozzle 212, thereby realizing the rotation of the spring part, a robot stepper motor 213 is fixedly installed at the end of the suction robot 21. The robot stepper motor 213 can drive the vacuum nozzle 212 to rotate.

[0052] An industrial camera 25 is fixedly mounted on the robotic arm housing 211 above the loading tray 23. The industrial camera 25 can collect the posture and position coordinates of the spring parts in the loading tray 23 in real time. The industrial camera 25 can be an existing industrial camera (resolution ≥ 5 million pixels).

[0053] Through the above structure, the disordered spring parts that fall into the feeding tray 23 are dispersed by the vibration of the voice coil motor 24. The posture of the spring parts is identified by the industrial camera 25, and the servo motor 214 of the suction robot 21 drives the vacuum nozzle 212 to move precisely along the X / Y / Z axes, picking up the spring parts based on the visual positioning results. The robot stepper motor 213 at the end of the suction robot 21 rotates the spring parts to an angle suitable for inspection by the visual inspection module and easy to place in the carrier belt based on the image captured by the industrial camera 25. Then, the suction robot 21 drives the vacuum nozzle 212 to transfer the spring parts to the inspection station. Specifically, a visual inspection module 3 is set at the inspection station, which includes a first inspection station, a second inspection station, and a third inspection station. The first and second inspection stations are located between the suction robot 21 and the material pulling module 5, and the third inspection station is located before the sealing of the carrier belt 4.

[0054] See Figure 1 As shown, a vision inspection module 1 31 and a vision inspection module 2 32 are obliquely arranged on the worktable 1 at the first inspection station and the second inspection station. The vision inspection module 1 31 is used to inspect the height of the gold dots of the spring parts, and the vision inspection module 2 32 is used to inspect the presence or absence of the gold dots of the spring parts and the cutting dimensions.

[0055] Both visual inspection module 1 31 and visual inspection module 2 32 include an inspection bracket 33 fixedly installed on the upper surface of the worktable 1 and an inspection camera assembly 34 set on the inspection bracket 33.

[0056] See Figure 3 As shown, the detection bracket 33 includes a support plate 331, an adjusting plate 332, an adjusting block 333, a limiting block 334, an adjusting bolt 335, and a fastening bolt (not shown in the figure).

[0057] The adjusting plate 332 is horizontally fixedly connected to the support plate 331. Specifically, the support plate 331 has a vertically formed waist-shaped connecting hole 3311. The fastening bolt passes through the connecting hole 3311 and is bolted to the adjusting plate 332, thereby adjusting the relative height of the adjusting plate 332 on the support plate 331.

[0058] An oblong adjustment hole 3321 is provided at one end of the adjusting plate 332 along its length. A limit block 334 is fixedly connected to the outside of the adjustment hole 3321 of the adjusting plate 332 by bolts. A limit groove 3341 is provided on the limit block 334. A sliding groove 3322 is provided on the adjusting plate 332 along its length. The adjusting block 333 can slide and be embedded in the sliding groove 3322 along its length. In order to fix the adjusting block 333 to the adjusting plate 332, a fastening bolt passes through the adjustment hole 3321 and is threaded into the adjusting plate 332. In addition, in order to facilitate fine adjustment of the relative position of the adjusting block 333 on the adjusting plate 332, the screw of the adjusting bolt 335 can be rotatably passed through the limit groove 3341 and threaded into the adjusting block 333. The adjusting bolt 335 is set along the length of the adjusting plate 332, and the outer diameter of the nut of the adjusting bolt 335 is larger than the size of the limit groove 3341.

[0059] The detection camera assembly 34 is horizontally fixedly connected to the adjustment block 333. This structure allows for vertical height adjustment and horizontal position adjustment of the detection camera assembly 34. When actually fixing the adjustment block 333, after installing the detection camera assembly 34, the relative position of the adjustment block 333 on the adjustment plate 332 can be adjusted by rotating the adjustment bolt 335. Then, the corresponding fastening bolts are tightened to fix the detection camera assembly 34 onto the adjustment plate 332.

[0060] The inspection brackets 33 of visual inspection module 1 31 and visual inspection module 2 32 have the same structure. The inspection camera assembly 34 differs in this embodiment due to the different inspection content. Specifically, the inspection camera assembly 34 in visual inspection module 1 31 includes a black and white industrial camera (model: MV-GED130E) located in the middle of the transfer path of the suction robot 21 and fixed on the adjustment block 333, in conjunction with a telecentric lens (model: WWH05-110ATV3) to photograph the height of the gold dots on the spring parts; the inspection camera assembly 34 in visual inspection module 2 32 includes a color industrial camera (model: MV-GED130C) located in the middle of the transfer path of the suction robot 21 and fixed on the adjustment block 333, in conjunction with a refractive prism and lens (model: MVL-HF5024M-10MP) to photograph the presence or absence of gold dots and the cutting size of the spring parts.

[0061] Further, see Figure 1 As shown, after the spring sheet parts are inspected by vision inspection module 1 31 and vision inspection module 2 32 and are found to be defective, the suction robot 21 can directly put the defective spring sheet parts into the waste bin 35 located on the worktable 1 inside the material pulling module 5.

[0062] See Figure 1 As shown, the material pulling module 5 is horizontally arranged on the workbench 1 outside the vision inspection module 1 31 and the vision inspection module 2 32. The carrier belt conveying module 6 includes a carrier belt winding assembly 61 and a carrier belt unloading assembly 62. The carrier belt 4 is unloaded by the carrier belt unloading assembly 62 and then wound up by the carrier belt winding assembly 61 after passing through the material pulling module 5.

[0063] Specifically, the carrier tape feeding assembly 62 is located in the working cavity 13 below the pulling module 5. The carrier tape feeding assembly 62 is the prior art, which includes a carrier tape feeding motor 621 fixed on the frame 11 in the working cavity 13 and a carrier tape feeding tray 622 fixedly connected to the output shaft of the carrier tape feeding motor 621. The carrier tape 4 is wound on the carrier tape feeding tray 622 and enters the pulling module 5 through the feeding through hole opened on the worktable 1. The carrier tape winding assembly 61 is located on the right side of the feeding module 5. The carrier tape winding assembly 61 is existing technology, which includes a carrier tape winding motor 611 fixed on the worktable 1 and a carrier tape winding reel 612 fixedly connected to the output shaft of the carrier tape winding motor 611. The carrier tape winding motor 611 drives the carrier tape winding reel 612 to rotate, and winds up the carrier tape 4 that has been pulled out from the feeding module 5 after being covered by the hot-pressed carrier tape cover film 7. At this time, the carrier tape unloading motor 621 needs to rotate synchronously to unload the material synchronously.

[0064] See Figure 1 , 6As shown in Figure 7, the material pulling module 5 is set on the workbench 1 outside the vision inspection module 1 31 and the vision inspection module 2 32. The material pulling module 5 includes a conveyor frame 51, a guide component 52 set on the conveyor frame 51 and used to guide the carrier belt 4, and a material pulling motor 54 that can drive the material pulling ratchet 53 to rotate. When the material pulling ratchet 53 rotates, it pulls the carrier belt 4.

[0065] Specifically, the conveyor frame 51 includes a base plate 511 that is horizontally fixed to the upper surface of the workbench 1 by bolts, a vertical plate 512 that is vertically fixed to the base plate 511 by bolts, and a horizontal plate 513 that is horizontally fixed to the vertical plate 512.

[0066] The guide assembly 52 includes a guide groove 521 formed along the length of the upper end face of the horizontal plate 513, and pressure plates 522 fixedly connected to the upper end faces of the horizontal plates 513 on both sides of the guide groove 521 by bolts. The pressure plates 522 extend above the guide groove 521. The carrier belt 4 is slidably embedded in the guide groove 521 below the pressure plate 522.

[0067] Furthermore, in order to allow the cover film 7 conveyed by the cover film conveying module 9 to cover the carrier belt 4 for heat pressing, a connecting plate 514 is vertically fixed to the horizontal plate 513 near one end of the carrier belt winding assembly 61 by bolts. A cover plate 515 is fixed to the connecting plate 514 by bolts. A cover plate groove 516 is provided on the lower end face of the cover plate 515. The cover plate groove 516 is located above the carrier belt 4. The cover film 7 conveyed by the cover film conveying module 9 covers the carrier belt 4 under the limiting and guiding effect of the cover plate groove 516.

[0068] The material pulling motor 54 is fixedly installed at one end of the vertical plate 512 near the carrier tape winding assembly 61. A material pulling ratchet 53 is fixedly sleeved on the output shaft of the material pulling motor 54 inside the vertical plate 512. The material pulling ratchet 53 includes a material pulling disc 531 fixedly sleeved on the output shaft of the material pulling motor 54 and material pulling protrusions 532 that are evenly distributed on the outer circumference of the material pulling disc 531 and match the existing carrier tape positioning holes 41 on the carrier tape 4. When the material pulling disc 531 rotates, each material pulling protrusion 532 can enter the carrier tape positioning hole 41 in sequence to pull the carrier tape 4 forward.

[0069] Furthermore, in order to improve the stability when pulling the carrier belt 4, two pull ratchet 53s are provided and respectively located at both ends of the vertical plate 512. The output shaft of one end of the pull motor 54 drives the pull ratchet 53 close to the carrier belt winding assembly 61 to rotate, and the output shaft of the other end of the pull motor 54 drives the pull ratchet 53 away from the carrier belt winding assembly 61 to rotate through the existing synchronous belt assembly 55. The pull ratchet 53 away from the carrier belt winding assembly 61 is rotatably connected to the vertical plate 512 through a rotating shaft.

[0070] See Figure 8As shown, to further improve the stability when pulling the carrier belt 4, the material pulling module 5 also includes a pressure belt assembly 56. The pressure belt assembly 56 includes a rotating plate 561 rotatably mounted on a vertical plate 512 on one side of the material pulling ratchet 53 via a rotating shaft, a fixed shaft 562 fixedly inserted on the rotating plate 561, and a pressure roller 563 rotatably connected to one end of the fixed shaft 562 above the material pulling ratchet 53. An avoidance ring groove 564 is formed on the outer circumference of the pressure roller 563 opposite to the material pulling protrusion 532, and the material pulling protrusion 532 can pass through the avoidance ring groove 564 when rotating. The two ends of the tension spring 565 are respectively hung on the rotating plate 561 and the vertical plate 512. Under the tension of the tension spring 565, the rotating plate 561 rotates to the material pulling ratchet 53, and the pressure roller 563 can press against the carrier belt 4 on the material pulling ratchet 53. By setting the ballast belt assembly 56, the carrier belt 4 can be pressed between the pressure roller 563 and the outer circumference of the pull plate 531.

[0071] See Figure 4 , 5 As shown, the hot-press packaging module 8 is set on the workbench 1 near the carrier tape winding assembly 61 and located on one side of the material pulling module 5. The hot-press packaging module 8 includes a vertical plate 81 fixedly installed on the base plate 511 on one side of the carrier tape 4 by bolts, and a hot-press cylinder 84 fixedly connected to the vertical plate 81. The hot-press cylinder 84 drives the hot-press knife 87 to contact the carrier tape cover film 7 to achieve the heat sealing operation.

[0072] The cover film conveying module 9 is mounted on the upright plate 81, and the carrier tape cover mold 7 it conveys can be placed on the carrier tape 4 and heat-sealed by the hot press knife 87. Specifically, the cover film conveying module 9 includes a mounting frame 91 fixed on the upright plate 81, a cover film conveying tray 92 rotatably mounted on the mounting frame 91, and a guide and tensioning assembly 93 for guiding and tensioning the carrier tape cover film 7. It should be noted that the cover film conveying module 9 is prior art, that is, the carrier tape cover film 7 is wound in rolls on the cover film conveying tray 92, and after the carrier tape 4 is heat-pressed with the carrier tape cover film 7, it pulls the carrier tape cover film 7, thereby driving the cover film conveying tray 92 to rotate to release the carrier tape cover film 7.

[0073] See Figure 9As shown, a fixing plate 83 is horizontally fixedly connected to the upright plate 81, and a downward pressing cylinder 82 is vertically fixedly connected to the fixing plate 83. A downward pressing plate 85 is horizontally fixedly connected to the guide rod of the downward pressing cylinder 82. A hot pressing cylinder 84 is fixedly connected to the lower end face of the downward pressing plate 85. A hot pressing frame 86 is provided below the hot pressing cylinder 84. A hot pressing knife 87 is fixedly connected to the lower part of the hot pressing frame 86. The hot pressing knife 87 is heated by an existing heating component. The temperature range of the hot pressing knife 87 is 80-200℃ with an accuracy of ±1℃. In order to improve the temperature stability of the hot pressing knife 87 and to avoid heat loss to a certain extent from being conducted to the hot pressing cylinder 84 through the hot pressing frame 86, a heat-resistant and heat-insulating existing synthetic stone is fixedly connected to the hot pressing frame 86. The synthetic stone is placed between the guide rod of the hot pressing cylinder 84 and the hot pressing knife 87. The temperature of the hot press knife 87 can be adjusted in real time by the existing temperature controller (model: Omron E5CC-RX2ASM-800), and the temperature can be monitored by the existing thermocouple sensor to ensure the heat sealing quality.

[0074] A sliding sleeve 851 is fixedly embedded in the lower pressure plate 85, and a sliding rod 831 is vertically fixedly connected to the fixed plate 83. The sliding rod 831 can slide inside the sliding sleeve 851. Two symmetrically arranged adjusting screws 88 are threadedly connected to the lower end of the lower pressure plate 85 in the vertical direction. The two ends of the tension spring 89 are respectively hung on the lower end of the adjusting screws 88 and the hot press frame 86. The guide rod of the hot press cylinder 84 abuts against the hot press frame 86 under the tension of the tension spring 89. The lower pressure cylinder 82 can drive the hot press cylinder 84 and the hot press knife 87 to move up and down. The lower pressure cylinder 82 can be a cylinder of model SMC CQ2B20-10DC, and the hot press cylinder 84 can be a high-speed cylinder of model SMC CQ2B16-5DC, thereby improving the hot press efficiency. The hot press cylinder 84 can drive the hot press knife 87 to move down and then hot press the carrier tape cover film 7 onto the carrier tape 4. By setting tension spring 89, it can buffer the hot pressing plate 87 during the process of hot pressing cylinder 84 driving hot pressing knife 87 to move down and hot press, so as to avoid damaging the carrier tape cover film 7.

[0075] See Figure 4 , 5 As shown, in this embodiment, the visual inspection module 3 further includes a third visual inspection module 36, which is mounted on the upright plate 81 at the third inspection station, located before the sealing of the carrier tape 4. The third visual inspection module 36 includes a line scan camera 361 fixedly mounted vertically downward on the upright plate 81, and a bowl-shaped light source 362 fixedly mounted on the upright plate 81 below the line scan camera 361. In this embodiment, the line scan camera 361 can be a Dalsa Spyder3 camera, which, in conjunction with the bowl-shaped light source 362, horizontally scans the cutting contour, size, and front and back directions of the spring sheet parts.

[0076] The image data obtained by visual inspection module 1 (31), visual inspection module 2 (32), and visual inspection module 3 (36) can be processed using existing dedicated visual processing boards (such as the Cognex VisionPro software platform), which have built-in deep learning algorithm models to achieve rapid defect identification.

[0077] The control system is electrically connected to and controls the feeding module 2, vision inspection module 3, material pulling module 5, carrier belt conveyor module 6, hot-press packaging module 8, and capping film conveyor module 9. The control system is existing technology and can use a PLC or industrial computer as its core, integrating vision inspection algorithms, stepper motor control programs, and hot-press parameter adjustment functions to achieve collaborative operation of each module and fault alarm.

[0078] The working principle and process of this embodiment are as follows:

[0079] Install each module according to this instruction manual. Figure 1 As shown;

[0080] 1. Loading stage: The spring parts enter the loading tray 23 through the outlet of the loading machine 22. After the spring parts in the loading tray 23 are dispersed by the vibration of the voice coil motor 24, the industrial camera 25 identifies the posture of the spring parts and generates coordinate data. The suction robot 21 accurately picks up the spring parts according to the data and moves the picked-up spring parts to the vision inspection module 31 of the first inspection station and the vision inspection module 32 of the second inspection station in sequence.

[0081] 2. Inspection at the first and second inspection stations: After the suction robot 21 picks up the spring piece, it moves to the first inspection station. The inspection camera component 34 of the vision inspection module 1 takes an image of the spring piece to detect the height of the gold dot on the spring piece. Then, the suction robot 21 moves the spring piece to the second inspection station. The inspection camera component 34 of the vision inspection module 2 takes an image of the spring piece to detect the presence or absence of gold dots and the cutting size of the spring piece. If the spring piece is found to be defective after being inspected by the vision inspection module 1 31 and the vision inspection module 2 32, the suction robot 21 can directly put the defective spring piece into the waste bin 35 located on the worktable 1 inside the material pulling module 5. If it is a qualified product, it continues to be transferred to the cavity on the carrier belt 4.

[0082] 3. Carrier belt conveying and third inspection station inspection: The pulling motor 54 drives the pulling ratchet 53 to rotate, realizing the fixed-distance conveying of the carrier belt 4. For each grid (corresponding to a carrier belt cavity), the suction robot 21 drops the spring parts into the corresponding cavity, triggering the hot-press packaging action; the line scan camera 361 of the vision inspection module 36 at the third inspection station takes images of whether the cutting edge and direction of the spring parts located in the cavity of the carrier belt 4 are correct, and re-measures the inspection dimensions. If there are defective products, an alarm is triggered and they are manually removed; the carrier belt 4 is entered into the guide groove 521 of the pulling module 5 by the cooperation of the carrier belt winding assembly 61 and the carrier belt unloading assembly 62; during the process of the carrier belt 4 being pulled, the carrier belt cover film 7 that has been hot-pressed on the carrier belt 4 pulls the cover film conveyor tray 92 to rotate, thereby realizing the unloading of the carrier belt cover film 7;

[0083] 4. Hot-press packaging: After receiving the arrival signal of the carrier tape 4, the control system controls the guide rods of the pressing cylinder 82 and the hot-press cylinder 84 of the hot-press packaging module 8 to extend and drive the hot-press knife 87 to press down. The hot-press knife 87 contacts the carrier tape cover film 7 for 0.3 seconds to complete the heat sealing of the carrier tape cover film 7 on the carrier tape 4, ensuring that the parts are sealed in the carrier tape. After that, the control system controls the guide rods of the pressing cylinder 82 and the hot-press cylinder 84 to retract.

[0084] 5. Cyclic operation: The carrier belt 4 continues to be conveyed, and the above steps are repeated until all the carrier belts 4 on the carrier belt unloading tray 622 have completed the placement of the spring parts, the carrier belt cover film 7 has been heat-pressed and packaged, and the carrier belt rewinding tray 612 has completed the winding.

[0085] Anything not described in this specification is existing technology and will not be elaborated here, as long as it meets the above working process.

[0086] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
