Description

Technical Field

[0001] This utility model relates to the field of thread inspection technology, specifically to a thread inspection device for irregularly shaped stamped parts. Background Technology

[0002] In the field of thread inspection for irregularly shaped stamped parts (such as nut plates), existing inspection equipment typically uses a combination of vision inspection systems and robotic arms to automate inspection and sorting for multiple threaded holes (such as hole 1, hole 2, and hole 3) on the product. The equipment uses vision sensors to inspect each threaded hole individually for defects such as size, thread integrity, and internal debris, determining whether each hole is defective. After inspection, the robotic arm transports the defective products to the corresponding defective product bins based on the results—if hole 1 is defective, the product is placed in the dedicated defective product bin for hole 1; if hole 2 is defective, the product is placed in the dedicated defective product bin for hole 2, and so on. This achieves preliminary sorting of defective products for single holes, meeting the needs of automated production to a certain extent.

[0003] There are many existing technologies for visual inspection equipment, such as: Chinese Patent Publication No. CN222800623U discloses a visual inspection device, relating to the field of visual inspection technology. This invention includes a conveyor belt with multiple placement trays fixedly connected to its top. First fixing plates are fixedly connected to both sides of the conveyor belt. A second fixing plate is positioned at the top between two first fixing plates, with its sides fixedly connected to the two first fixing plates respectively. A first camera is fixedly connected to the bottom of the second fixing plate, positioned above the placement trays. Second cameras are fixedly connected to the bottom of adjacent sides of the two first fixing plates. A flipping assembly is positioned between the two first fixing plates, and a rotating assembly is positioned inside the placement trays. This invention, through the flipping assembly, allows parts to be flipped during inspection, thereby enabling inspection of the bottom of the parts and improving the completeness and effectiveness of the inspection.

[0004] However, when multiple threaded holes on the same irregular stamped part are defective at the same time (such as hole 1 and hole 2 being defective at the same time), the equipment lacks a targeted classification mechanism and can only classify the product into one defective product box. This makes it inconvenient to accurately determine all the defective locations of the product during subsequent quality traceability, which seriously affects the analysis of defect causes and process optimization. Furthermore, the dispersed arrangement of multiple independent defective product boxes not only increases the overall footprint of the equipment, but also prolongs the movement path of the robotic arm when handling defective products, increasing the complexity of the operation. This may adversely affect the stability of the production cycle and make it difficult to meet the needs of high-efficiency production.

[0005] Therefore, we propose a thread inspection device for irregularly shaped stamped parts. Utility Model Content

[0006] This utility model provides a defective box for irregularly shaped stamped parts, which, by setting a defective box with a separator, an infrared emitter, and a motor inside the support, and in conjunction with a conveying device, a robotic arm, a vision inspection device, and a flow guide, enables different defective workpieces to be accurately classified and spaced in the same defective box under the control of the infrared emitter of the separator. This solves the problems mentioned in the background art, namely: When multiple threaded holes on the same irregular stamped part are defective at the same time, it is difficult to classify them accurately, which leads to difficulties in traceability and hinders quality analysis. In addition, multiple independent defective product boxes occupy a large area, increase the complexity of robot movement, and affect the stability of production cycle.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] Please see Figures 1-7 The diagram shows a thread inspection device for irregularly shaped stamped parts, including a support 1, a top plate 11 on the top of the support 1, a defect box 2 inside the support 1, a separation component 24 inside the defect box 2, and a motor at the end of the separation component 24 that protrudes from the support 1. An infrared transmitter 25 is provided between the separator 24 and the inner wall of the defective box 2. The infrared transmitter 25 is used to control the rotation path of the motor, and the separator 24 is used to classify and separate different workpieces inside the defective box 2.

[0021] When implementing, refer to Figure 1 As shown, a conveying device 12 is provided on the top of the top plate 11, and robotic arms 13 are provided on both sides of the conveying device 12. A vision inspection device 14 is provided on the top of the conveying device 12, and a groove is provided inside the top plate 11.

[0022] See Figure 4 As shown, the top of the defective box 2 is provided with a cover 21. The outer wall of the cover 21 is provided with multiple buckles 22. The buckles 22 are snapped onto the outer wall of the defective box 2. A flow guide chamber 15 is fixedly connected between the cover 21 and the top plate 11. The flow guide chamber 15 has a conical discharge structure. The inside of the cover 21 has a groove at the interface of the flow guide chamber 15.

[0023] First, the irregularly shaped stamped parts are conveyed by the conveying device 12 at the top of the top plate 11. When passing the vision inspection device 14 at the top of the conveying device 12, the vision inspection device 14 inspects the threaded holes on the product, such as hole 1, hole 2, and hole 3, to determine whether each hole has defects and whether the defect type is a single hole defect or multiple holes defective at the same time. After the inspection is completed, the robotic arms 13 on both sides of the conveying device 12 grab the defective products according to the inspection results and transfer them to the groove inside the top plate 11. The irregularly shaped stamped parts are guided to fall into the defect box 2 through the guide chamber 15 connected below the groove. The purpose of the conical feeding structure of the guide chamber 15 is to guide the defective products to fall accurately into the corresponding section in the defect box 2, avoiding deviation or jamming.

[0024] The multiple clips 22 on the outer wall of the cover 21 are fastened to the outer wall of the defective box 2. The purpose of the clips 22 is to achieve quick fixation and separation of the cover 21 and the defective box 2 through the detachable connection of the clips 22. When it is necessary to replace the partition of the separator 24 to adapt to the testing requirements of different specifications of products, the clips 22 can be easily released to remove the cover 21. After the adjustment or replacement of the separator 24 is completed, the cover 21 can be re-fixed by the clips 22. This not only ensures the stability of the connection between the cover 21 and the defective box 2 when the equipment is working, but also provides operational convenience for the later maintenance and upgrading of the separator 24, taking into account both structural reliability and maintenance flexibility.

[0025] Driven by a motor, the separator 24 inside the defective box 2 rotates. The infrared emitter 25, located between the separator 24 and the inner wall of the box, controls the motor to rotate the separator 24 to the corresponding angle based on the defect type determined by the visual inspection device 14. This ensures that the different partitions formed by the separator 24 are precisely aligned with the discharge port of the guide chamber 15, thus classifying and separating products of different defective types inside the defective box 2. When it is necessary to retrieve or place defective products, the door panel 230 can be opened and closed via the electromagnetic lock controller 231 on the sealing assembly 23 of the defective box 2, enabling safe and convenient operation. The entire process, through the coordinated operation of various components, achieves automated detection, precise classification, and efficient storage of defective products.

[0026] See Figure 5 As shown, the partition assembly 24 includes a rotating rod 240, which is movably connected inside the defective box 2. A motor is located at the end of most of the rotating rods 240 that protrudes from the defective box 2 and the support 1. Two support plates 241 are fixedly connected to the outer wall of the defective box 2. A cylinder 242 is engaged between the rotating rod 240 and the outer wall of the support plate 241. Multiple partitions 243 are fixedly connected to the outer wall of the cylinder 242, and multiple infrared emitters 25 are provided on the outer wall of the cylinder 242.

[0027] Since the rotating rod 240 is movably installed inside the defective box 2, its end that passes through the defective box 2 and is connected to the support 1 is connected to a motor, which can drive the entire structure to rotate under the drive of the motor. At this time, the rotating rod 240 and the support plate 241 are connected to the cylinder 242 by a snap-fit ​​method, so that the cylinder 242 can rotate synchronously with the rotating rod 240. The multiple partitions 243 fixed on the outer wall of the cylinder 242 divide the interior of the defective box 2 into multiple independent partitions, wherein the number of partitions 243 is greater than or equal to the number of defective combinations corresponding to the number of product thread holes.

[0028] When the equipment is running, the motor drives the rotating rod 240 to rotate, which in turn drives the cylinder 242 and the partition 243 to rotate synchronously. Combined with the control of the rotation angle of the motor by the infrared transmitter 25, the different partitions separated by the partition 243 can be accurately aligned with the discharge port of the guide chamber 15, thereby realizing the classification and storage of different types of defective products.

[0029] When disassembly is required, the operator can first open the cover 21, and then directly apply axial force to the cylinder 242 to separate the cylinder 242 from the rotating rod 240 and remove it. If it is necessary to replace the cylinder 242 with a different number or spacing of partitions 243, simply align the groove or protrusion on the inner wall of the new cylinder 242 with the corresponding protrusion or groove on the rotating rod 240 and apply axial force to complete the snap-fit. The whole process does not rely on complicated tools, and quick disassembly and assembly are achieved only through the adaptation and separation of physical structures, so as to conveniently adjust the number and size of the partitions in the defective box 2 and flexibly adapt to the inspection and classification needs of different specifications of irregular stamped parts.

[0030] See Figure 6 As shown, multiple infrared transmitters 25 are located at the intervals between two partitions 243. A first receiver 250 is provided on the inner wall of the defective box 2 below the flow guide chamber 15. A groove is provided on the outer wall of the defective box 2. A second receiver 251 is provided on the inner wall of the defective box 2 above the groove.

[0031] Since multiple infrared emitters 25 are respectively installed at the interval of two partitions 243 on the outer wall of the cylinder 242, and rotate synchronously with the cylinder 242, each infrared emitter 25 corresponds to a specific defect location storage area, such as single-hole defects, double-hole composite defects, etc., forming a partition correspondence relationship of the emitters; through the first receiver 250 located directly below the flow guide chamber 15 on the inner wall of the defect box 2, and the second receiver 251 located above the groove, the three work together to form the core component for positioning and control, realizing the adjustment of the rotation angle of the partition component 24.

[0032] When the equipment is running, after the visual inspection device 14 determines the type of product defect, the system will automatically match the corresponding infrared transmitter 25. The motor then drives the rotating rod 240, cylinder 242 and infrared transmitter 25 to rotate synchronously. When the matched infrared transmitter 25 rotates to the position opposite to the first receiver 250, the first receiver 250 receives the signal and provides real-time feedback. The motor immediately stops rotating, ensuring that the interval zone where the infrared transmitter 25 is located is accurately aligned with the discharge port of the guide chamber 15, so that defective products can fall smoothly into the corresponding storage zone along the conical guide chamber 15, achieving accurate classification and storage.

[0033] When defective products need to be removed, the operator can select the target storage compartment according to the requirements. The motor drives the cylinder 242 to rotate again, causing the infrared transmitter 25 corresponding to that compartment to rotate and align with the second receiver 251. After the two sense each other, the system controls this state to be maintained for 5 seconds to ensure the compartment position is stable. Then, the locking state of the sealing component 23 is automatically unlocked, allowing the operator to open the door panel 230 and remove the defective products from the corresponding compartment. Through the precise cooperation of the infrared transmitter 25 and the two receivers, the positioning accuracy during defective product classification is ensured, and the convenience and safety of the retrieval and placement operations are achieved. The smooth linkage of each link improves the reliability and efficiency of the equipment operation.

[0034] See Figure 7 As shown, a sealing component 23 is provided inside the groove of the defective box 2. The sealing component 23 includes a door panel 230, which is movably engaged inside the groove of the defective box 2. A hinge 232 is provided between the door panel 230 and the outer wall of the defective box 2. An electromagnetic lock controller 231 is provided between one side of the door panel 230 and the inner wall of the groove of the defective box 2.

[0035] The door panel 230 is movably engaged within the groove of the defective box 2. A hinge 232 between the door panel 230 and the outer wall of the defective box 2 provides rotational support for the door panel 230, allowing it to open and close flexibly. An electromagnetic lock controller 231, located between one side of the door panel 230 and the inner wall of the groove, is responsible for locking and unlocking the door panel 230. During normal operation, the electromagnetic lock controller 231 is locked, and the door panel 230 is tightly engaged within the groove, ensuring the airtightness of the defective box 2 and preventing the entry of external debris or accidental falling of defective products. When it is necessary to remove defective products, after the infrared transmitter 25 and the second receiver 251 are aligned and held stably for 5 seconds, the electromagnetic lock controller 231 receives a signal and unlocks. The operator can then rotate the door panel 230 via the hinge 232 to open the groove and remove the defective product from the corresponding section. After removal and placement, the door panel 230 is closed, and the electromagnetic lock controller 231 relocks, restoring the sealed state.
