Description

Technical Field

[0001] The present application belongs to the technical field of pin detection, and specifically relates to a detection device for detecting the appearance, size and R-arc of a pin. Background Art

[0002] A connector is a device that connects two active devices and is an electronic component used to transmit and exchange current or optical signals between electronic system devices. Independently or in conjunction with cables, it transmits current or optical signals between devices, components, equipment, and subsystems, while preventing signal distortion and energy loss between systems. Pins are a key component in connectors. To ensure connector quality, molded pins must be inspected. Pin inspection devices have been developed to improve pin inspection efficiency.

[0003] In related art, a pin inspection device includes a loading mechanism, a conveying mechanism, and a detection mechanism. The detection mechanism is located on the side of the conveying mechanism along its length, and the conveying end of the conveying mechanism has a good product discharge channel and a defective product discharge channel. When inspecting pins, the loading mechanism continuously and sequentially feeds the pins into the conveying mechanism, which then conveys the pins. During the conveying process, the detection mechanism collects image information of the pins and uploads it to an analysis system for visual inspection of the pins. When the pins are transported to the conveying end of the conveying mechanism, pins that pass the analysis by the analysis system fall through the good product discharge channel, while pins that fail the analysis by the analysis system fall through the defective product discharge channel, completing the pin inspection.

[0004] However, since the detection mechanism is arranged on the side of the conveying mechanism in the length direction, and the good product discharge channel and the defective product discharge channel are located at the end of the conveying mechanism, this increases the required conveying path for the pins, thereby affecting the detection efficiency of the pins. At the same time, it also causes the size of the pin detection device to be larger, greatly increasing the difficulty of miniaturizing the design of the pin detection device. Utility Model Content

[0005] The present application provides a detection device for detecting the appearance, size and R-arc of a pin, so as to shorten the conveying path of the pin, improve the detection efficiency of the pin, and reduce the volume of the detection device, thereby greatly reducing the difficulty of miniaturizing the design of the detection device.

[0014] By adopting the above technical solution, when using the detection device of the present application to detect the appearance, size and R arc of the pin, a batch of pins are first poured into the feeding assembly, so that the feeding assembly conveys the pins in sequence, and then the pins fall to the turntable through the conveying end, and the driving member drives the turntable so that the pins rotate to the bottom of the image acquisition member under the action of the turntable, so that the image acquisition member captures the image of the pin and uploads it to the image analysis system to determine whether the pin is qualified. When the image analysis system analyzes that the pin is a qualified product, the pin continues to rotate with the turntable. When this pin is After the pin rotates to the good product discharge position, the good product rejection unit drives the pin to move to the good product discharge position, so that the good product pins are collected at the good product discharge position; when the image analysis system analyzes that the pin is a defective product, the pin continues to rotate with the turntable. When the pin rotates to the defective product discharge position, the defective rejection unit drives the pin to move to the defective product discharge position, so that the defective pins are collected at the defective product discharge position. In this process, the appearance, size and R arc of the pin are detected, and the qualified pins and the unqualified pins are classified and collected.

[0015] In the present application, a turntable is provided so that the good product discharge position and the defective product discharge position are arranged along the circumference of the turntable, thereby greatly shortening the path required for transporting the pins when testing the pins, thereby greatly improving the inspection efficiency of the pins, and at the same time greatly shortening the length of the detection device, thereby greatly reducing the volume of the detection device, thereby greatly reducing the difficulty of miniaturizing the detection device.

[0016] Optionally, the turntable has a central area and a conveying area surrounding the central area, and the conveying end is located directly above a portion of the conveying area.

[0017] By adopting the above technical solution, since the conveying end is located above part of the conveying area, the pins falling through the conveying end fall into the conveying area, and the conveying area is arranged around the central area, thereby increasing the number of pins that can be accommodated on the turntable at the same time on the one hand, and shortening the path when driving the pins to the outside of the turntable on the other hand, thereby further improving the detection efficiency of the pins, and greatly reducing the difficulty of driving the pins to the outside of the turntable.

[0018] Optionally, a protrusion is provided in the central area, and the detection device further comprises a blocking ring located outside the turntable, and the blocking ring and the protrusion together form a conveying channel.

[0019] By adopting the above technical solution, since the blocking ring and the protrusion jointly form a conveying channel, the outer circumference of the protrusion and the inner circumference of the blocking ring can block the pins, so as to prevent the pins from moving due to centrifugal force during the rotation of the turntable, thereby ensuring the stability of the pins and the detection efficiency of the pins.

[0020] Optionally, the blocking ring includes a first section and a second section spaced apart from the first section, and a good product discharge gap and a defective product discharge gap corresponding to the good product discharge position and the defective product discharge position are formed between the two ends of the second section and the two ends of the first section respectively.

[0021] By adopting the above technical solution, since good product discharge notches and defective product discharge notches corresponding to the good product discharge position and defective product discharge position are respectively formed between the two ends of the second section and the two ends of the first section, good product pins can enter the good product discharge position through the good product discharge notches, and defective product pins can enter the defective product discharge position through the defective product discharge notches, thereby greatly reducing the difficulty of driving the good product pins and the defective product pins to the outside of the turntable.

[0022] Optionally, the rejection part includes a first air outlet pipe arranged corresponding to the good product discharge position and a second air outlet pipe arranged corresponding to the defective product discharge position, so that the good product pins are blown down to the good product discharge position under the action of the gas flowing out through the first air outlet pipe, and the defective product pins are blown down to the defective product discharge position under the action of the gas flowing out through the second air outlet pipe. The first air outlet pipe constitutes the good product rejection part, and the second air outlet pipe constitutes the defective product rejection part.

[0023] By adopting the above technical solution, when the good product pins rotate to the good product discharge position, the gas discharged through the first air outlet pipe blows toward the good product pins, and then the good product pins are moved to the outside of the turntable and fall to the good product discharge position under the action of the gas; when the defective product pins rotate to the defective product discharge position of the device, the gas discharged through the second air outlet pipe blows toward the defective product pins, and then the defective product pins are moved to the outside of the turntable and fall to the defective product discharge position under the action of the gas, thereby achieving driving of the good product pins and the defective product pins to the outside of the turntable.

[0024] Optionally, the first air outlet pipe includes a first air inlet section extending from the outer side of the turntable to the inner side of the turntable and a first air outlet section extending obliquely downward from the first air inlet section toward the outer side of the turntable;

[0025] And / or, the second air outlet pipe includes a second air inlet section extending from the outer side of the turntable to the inner side of the turntable and a second air outlet section extending obliquely downward from the second air inlet section toward the outer side of the turntable.

[0026] By adopting the above technical solution, since the first air outlet section is arranged to extend downwardly and obliquely toward the outside of the turntable, the gas discharged through the first air outlet section is blown directly onto the good-quality pins, thereby ensuring that the good-quality pins can be separated from the turntable and fall to the good-quality unloading position. At the same time, the driving efficiency of the good-quality pins can be guaranteed and the influence of the gas discharged through the first air outlet section on other pins can be avoided.

[0027] Since the second air outlet section is arranged to extend downwardly and obliquely toward the outer side of the turntable, the gas discharged through the second air outlet section is blown directly toward the defective pins, so as to ensure that the defective pins can be separated from the turntable and fall to the defective material discharge position. At the same time, the driving efficiency of the defective pins can be guaranteed and the influence of the gas discharged through the second air outlet section on other pins can be avoided.

[0029] By adopting the above technical solution, since the mounting plate is arranged on the support column, the support column can support the mounting plate to increase the stability of the mounting plate. At the same time, the first air outlet pipe and the second air outlet pipe are arranged on the mounting plate, thereby increasing the stability of the first air outlet pipe and the second air outlet pipe to avoid the situation where the first air outlet pipe and the second air outlet pipe may conflict with the turntable due to ventilation.

[0030] Optionally, the detection device further includes a blocking ring located outside the turntable, the blocking ring being provided with a detector for detecting the pins, the detector being electrically connected to the driving member so that the detector sends a start signal to the driving member after detecting that the turntable has the pins.

[0031] By employing this technical solution, after the pins are dropped onto the turntable by the loading assembly, the detector detects the presence of pins on the turntable and then initiates a start signal to the driver, which activates and drives the turntable, thereby rotating the pins to inspect their appearance, size, and R-curve. Because the detector activates and deactivates the driver based on the presence of pins on the turntable, automatic control of the driver is achieved, significantly reducing its operating time and, in turn, the energy consumption of the inspection device.

[0032] Optionally, two material discharge channels are provided on the circumference of the turntable, each of the material discharge channels has a feed port facing the turntable, and the two material discharge channels respectively form the good product discharge position and the defective product discharge position.

[0033] By adopting the above technical solution, when the good product pin rotates to the good product unloading position, the good product rejection part drives the good product pin, and then the good product pin enters the unloading channel corresponding to the good product unloading position and falls along the unloading channel, so that the unloading channel guides the good product pin to ensure the stability of the good product pin when falling.

[0034] When the defective pin rotates to the defective unloading position, the defective rejection part drives the defective pin, and then the defective pin enters the unloading channel corresponding to the defective unloading position and falls along the unloading channel, so that the unloading channel guides the defective pin to ensure the stability of the defective pin when falling.

[0035] Optionally, a slide plate extending upward toward the turntable is provided at the feed port, and wing plates are provided on both sides of the slide plate.

[0036] By adopting the above technical solution, when the good pins rotate to the good unloading position, the good rejection part drives the good pins, and then the good pins fall onto the corresponding slide and enter the unloading channel along the slide. At this time, the wing plates on both sides of the slide block the good pins to ensure that the good pins can enter the unloading channel, so as to achieve the effect of facilitating the collection of good pins.

[0037] When the defective pins rotate to the defective unloading position, the defective rejection part drives the defective pins, and then the defective pins fall onto the corresponding slide and enter the unloading channel along the slide. At this time, the wing plates on both sides of the slide block the defective pins to ensure that the defective pins can enter the unloading channel, so as to achieve the effect of facilitating the collection of defective pins.

[0056] It should be noted that the above-mentioned "good product unloading position 212 is arranged on the circumferential side of the turntable 21 and is located on the side of the detection component 3 away from the first direction" and "defective product unloading position 213 is arranged on the circumferential side of the turntable 21 and is located on the side of the detection component 3 away from the first direction" means that when the pin follows the rotation of the turntable 21, it first rotates to the detection component 3, then rotates to the good product unloading position 212, and finally rotates to the defective product unloading position 213, or when the pin follows the rotation of the turntable 21, it first rotates to the detection component 3, then rotates to the defective product unloading position 213, and finally rotates to the good product unloading position 212.

[0057] It is understood that image acquisition component 31 is a camera capable of capturing images of the pins. The inspection device also includes an image analysis system and a PLC control system connected to the image analysis system. Image acquisition component 31 is connected to the image analysis system, which then transmits the captured pin images to the image analysis system. The image analysis system analyzes the images to determine whether the pins meet the requirements of appearance, size, and R-curve. Qualified pins are considered good, while unqualified pins are considered defective. The image analysis system transmits the image analysis results to the PLC control system, which then controls the rejection component 4, causing the good rejection unit 41 to drive good pins to the good material discharge position 212, and the defective rejection unit 42 to drive defective pins to the defective material discharge position 213.

[0058] When using the detection device of the present application to detect the appearance, size and R arc of the pins, first pour the batch of pins into the feeding assembly 1, so that the feeding assembly 1 conveys the pins in sequence, and then the pins fall to the turntable 21 through the conveying end, and the driving member 22 drives the turntable 21 so that the pins rotate to the bottom of the image acquisition member 31 under the action of the turntable 21, so that the image acquisition member 31 captures the image of the pins and uploads it to the image analysis system to determine whether the pins are qualified. When the image analysis system analyzes that the pins are qualified products, the pins continue to rotate with the turntable 21.

When the pin rotates to the defective product discharge position 213, the defective product rejection unit 42 drives the pin to move to the defective product discharge position 213, so that the defective pins are collected at the defective product discharge position 213. In this process, the appearance, size and R arc of the pin are detected, and the qualified pins and unqualified pins are classified and collected.

[0059] In the present application, by setting up the turntable 21, the good product discharge position 212 and the defective product discharge position 213 are set along the circumference of the turntable 21, thereby greatly shortening the path required for transporting the pins when testing the pins, thereby greatly improving the inspection efficiency of the pins, and at the same time greatly shortening the length of the detection device, thereby greatly reducing the volume of the detection device, and greatly reducing the difficulty of miniaturizing the detection device.

[0060] The present application does not make any specific limitation on the structure of the feeding component 1. Preferably, refer to Figure 1 and Figure 2 The loading assembly 1 includes a vibrating plate 11 and a linear vibrator 12. The vibrating plate 11 has a spiral feeding channel.

[0066] The present application does not specifically limit the structure of the protrusion 211. Preferably, the protrusion 211 is a plate-shaped structure provided on the turntable 21 to increase the structural strength of the turntable 21 and also to increase the stability of the connection between the turntable 21 and the driving member 22.

Preferably, refer to Figure 3 The rejecting part 4 includes a first air outlet pipe provided corresponding to the good product discharge position 212 and a second air outlet pipe provided corresponding to the defective product discharge position 213, so that the good product pins are blown down to the good product discharge position 212 under the action of the gas flowing out through the first air outlet pipe, and the defective product pins are blown down to the defective product discharge position 213 under the action of the gas flowing out through the second air outlet pipe.

[0072] When the good pins rotate to the good product discharge position 212, the gas discharged through the first gas outlet pipe blows toward the good pins, and then the good pins are moved to the outside of the turntable 21 and fall to the good product discharge position 212 under the action of the gas; when the defective pins rotate to the defective product discharge position 213, the gas discharged through the second gas outlet pipe blows toward the defective pins, and then the defective pins are moved to the outside of the turntable 21 and fall to the defective product discharge position 213 under the action of the gas, so as to achieve driving the good pins and the defective pins to the outside of the turntable 21.

[0073] Further, refer to Figure 3 The first air outlet pipe includes a first air inlet section extending from the outside of the turntable 21 to the inside of the turntable 21, and a first air outlet section extending obliquely downward from the first air inlet section toward the outside of the turntable 21.

[0075] Further, refer to Figure 3The detection device also includes a mounting frame 7, which includes a support column 71 and a mounting plate 72 provided on the top of the support column 71. The mounting plate 72 is located above the turntable 21, and the first air outlet pipe and the second air outlet pipe are both provided on the mounting plate 72.

[0076] Since the mounting plate 72 is arranged on the support column 71, the support column 71 can support the mounting plate 72 to increase the stability of the mounting plate 72. At the same time, the first air outlet pipe and the second air outlet pipe are arranged on the mounting plate 72, thereby increasing the stability of the first air outlet pipe and the second air outlet pipe to avoid the situation where the first air outlet pipe and the second air outlet pipe may conflict with the turntable 21 due to ventilation.

[0077] In other embodiments, the good product rejection part 41 and the defective product rejection part 42 can also be any one of a cylinder, a hydraulic cylinder or an electric push rod, that is, when the good product pins or the defective product pins are driven to the outside of the turntable 21, the piston rod moves and applies a force toward the outside of the turntable 21 to the pins.

[0078] In a preferred embodiment, referring to Figure 3 The detection device also includes a blocking ring 6 located outside the turntable 21. The blocking ring 6 is provided with a detector 611 for detecting the pin. The detector 611 is electrically connected to the driving member 22 so that the detector 611 sends a start signal to the driving member 22 after detecting that the turntable 21 has a pin.

[0079] It is understandable that the detector 611 is connected to the PLC control system signal, and then when the detector 611 detects that there is a pin on the turntable 21, the detector 611 sends a signal to the PLC control system, and the PLC control system controls the driving member 22 to start.

[0080] Since the detector 611 can control the start and stop of the driving member 22 according to whether there is a pin on the turntable 21, automatic control of the driving member 22 is achieved, which greatly shortens the working time of the driving member 22 and greatly reduces the energy consumption of the detection device.

[0081] The present application does not specifically limit the structure of the good product discharge position 212 and the defective product discharge position 213. Preferably, refer to Figure 1 and Figure 4 Two material discharge channels 8 are provided on the peripheral side of the turntable 21. The material discharge channels 8 have a feed port facing the turntable 21. The two material discharge channels 8 respectively form a good product discharge position 212 and a defective product discharge position 213.

[0082] It can be understood that the two material discharge channels 8 are arranged at intervals along the circumference of the turntable 21 .

[0083] When the good product pins rotate to the good product unloading position 212, the good product rejection part 41 drives the good product pins, and then the good product pins enter the unloading channel 8 corresponding to the good product unloading position 212 and fall along the unloading channel 8, so that the unloading channel 8 guides the good product pins to ensure the stability of the good product pins when falling.

[0084] When the defective pin rotates to the defective unloading position 213, the defective rejection part 42 drives the defective pin, and then the defective pin enters the unloading channel 8 corresponding to the defective unloading position 213 and falls along the unloading channel 8, so that the unloading channel 8 guides the defective pin to ensure the stability of the defective pin when falling.

[0085] Further, refer to Figure 4 A slide plate 81 extending upward toward the turntable 21 is provided at the feed port, and wing plates 82 are provided on both sides of the slide plate 81.

[0086] When the good pins rotate to the good unloading position 212, the good rejection part 41 drives the good pins, and then the good pins fall onto the corresponding slide 81 and enter the unloading channel 8 along the slide 81. At this time, the wing plates 82 on both sides of the slide 81 block the good pins to ensure that the good pins can enter the unloading channel 8, so as to achieve the effect of facilitating the collection of the good pins.

[0087] When the defective pins rotate to the defective unloading position 213, the defective rejecting part 42 drives the defective pins, so that the defective pins fall onto the corresponding slide 81 and enter the unloading channel 8 along the slide 81. At this time, the wing plates 82 on both sides of the slide 81 block the defective pins to ensure that the defective pins can enter the unloading channel 8, so as to achieve the effect of facilitating the collection of the defective pins.

[0088] Furthermore, the lower ends of the two feeding channels 8 pass through the fixed plate 51 and are connected to the internal space of the frame 5. The frame 5 is provided with a collection box with an open top corresponding to the two feeding channels 8, so that the good pins and the defective pins are collected in different collection boxes respectively, so as to facilitate the staff to classify and organize the two.

[0089] In other embodiments, both the good product discharge point 212 and the defective product discharge point 213 may also be planar structures formed by areas set on the fixed plate 51 .

[0090] In a preferred embodiment, referring to Figure 1 and Figure 2The detection component 3 also includes a ring light 32 located between the turntable 21 and the image acquisition component 31, and the ring light 32 is located directly below the image acquisition component 31, so that the ring light 32 can fill in the light for the pins located below the image acquisition component 31, thereby improving the image acquisition quality of the image acquisition component 31 and ensuring the accuracy of pin detection.

[0091] In a preferred embodiment, referring to Figure 5 The detection device also includes a hood 9 provided on the frame 5 and located above the fixed plate 51. The hood 9 has an openable door 91 to cover and protect the feeding component 1, the detection component 3 and the turntable component 2, thereby avoiding the influence of other factors on the pin detection and ensuring the accuracy of the pin detection.

[0092] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0093] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.

[0094] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
