[0050] The specific embodiments of this utility model are further described below with reference to the accompanying drawings. The scope of protection of this utility model is not limited to the description of the following embodiments.

[0051] This embodiment provides a socket testing device that can be connected to the socket factory production line to automatically test the appearance and socket conductivity of the wall switch socket 22, determine whether the socket 22 is qualified, and further automatically separate good sockets 22 from defective sockets 22.

[0052] like Figure 1 As shown, the socket testing equipment provided in this application includes a testing platform 1. The testing platform 1 is equipped with a controller 4, a transmission mechanism 2, a feeding mechanism 3, an appearance inspection mechanism 5, a socket continuity testing mechanism 9, and a discharging mechanism 7. The controller 4 is electrically connected to the feeding mechanism 3, the appearance inspection mechanism 5, the socket continuity testing mechanism 9, and the discharging mechanism 7, respectively.

[0053] The feeding mechanism 3 is used to transfer the socket 22 to be tested to the transmission mechanism 2;

[0054] The transmission mechanism 2 is used to transmit the socket 22 to the appearance inspection mechanism 5, the socket conductivity inspection mechanism 9 and the unloading mechanism 7;

[0055] The appearance inspection mechanism 5 includes a camera 51, which is used to capture images of the socket 22 and transmit them to the controller 4, and the controller inspects the appearance of the socket 22 based on the captured images.

[0056] The socket continuity detection mechanism 9 includes a second drive mechanism 92 and at least one plug 95 connected to the second drive mechanism 92. The plug 95 includes a plurality of detection pins 954 for inserting into the socket 22 to detect the continuity of the socket.

[0057] The feeding mechanism 7 includes at least two feeding channels 30. The feeding mechanism 7 receives a control signal from the controller 4 and outputs the socket 22 on the transmission mechanism 2 from one of the at least two feeding channels 30.

[0058] The socket inspection equipment in this embodiment uses an appearance inspection mechanism 5 to automatically inspect the appearance of the socket 22, and a socket continuity inspection mechanism 9 to automatically inspect the continuity of the sockets. This avoids manual inspection, significantly improving production efficiency and simplifying the structure. The unloading mechanism 7 automatically separates good and defective sockets, saving labor costs and increasing efficiency.

[0059] In another possible embodiment of this application, the controller 4 marks the sockets 22 with defects in appearance as a first mark, and the controller 4 marks the sockets 22 with blocked sockets as a second mark. The unloading mechanism 7 includes three unloading channels 30. The controller 4 transmits control signals to the unloading mechanism 7 according to the marking information (first mark, second mark, no mark). The unloading mechanism 7 separates the sockets 22 according to the first mark, second mark, and no mark, and outputs the sockets 22 from the three unloading channels 30 respectively. This enables the separation of sockets with defects in appearance, sockets with blocked sockets, and good sockets, improving accuracy and facilitating the subsequent classification and repair of defective sockets 22.

[0060] Of course, in another possible embodiment, the controller 4 marks the sockets 22 with defects in appearance and sockets 22 with blocked holes. The unloading mechanism 7 includes two unloading channels 30. The unloading mechanism 7 separates the sockets 22 according to the first mark and the unmarked ones, and outputs the sockets 22 from the two unloading channels 30 respectively.

[0061] It should be noted that the order of the appearance inspection mechanism 5 and the jack conductivity inspection mechanism 9 can be interchanged, and both are within the protection scope of this utility model.

[0062] One embodiment of the feeding mechanism 3 includes a feeding robot that picks up the socket 22 to be inspected and places it onto the transmission mechanism 2. Preferably, the inspection table 1 is equipped with a feeding platform 12, which is connected to an external socket factory production line or is placed manually on by the user. The feeding mechanism 3 then picks up the socket 22 from the feeding platform 12 and places it onto the transmission mechanism 2. In a less desirable embodiment, the socket 22 is placed directly onto the transmission mechanism 2 by the user, eliminating the need for the feeding mechanism 3.

[0063] Another embodiment of the feeding mechanism 3 is that the feeding mechanism 3 includes a feeding cylinder and a push rod connected to the feeding cylinder. The feeding cylinder drives the push rod to push the socket 22 to be tested onto the transmission mechanism 2.

[0064] Another embodiment of the feeding mechanism 3 is that the feeding mechanism 3 includes a feeding conveyor belt connected to the transmission mechanism 2, and the feeding conveyor belt sequentially transmits the sockets 22 to be tested to the transmission mechanism 2.

[0065] like Figure 1 , 5As shown, in a preferred embodiment of the transmission mechanism 2, the transmission mechanism 2 includes a transmission belt 20; the transmission belt 20 is provided with a plurality of fixing grooves 21 at intervals, and the feeding mechanism 3 picks up the socket 22 and places it in the fixing groove 21, the fixing groove 21 fixing the socket 22 in a fixed position. The transmission mechanism 2 transmits the socket sequentially to the first inspection station corresponding to the appearance inspection mechanism 5, the second inspection station corresponding to the socket conductivity inspection mechanism 9, and the unloading mechanism 7 via the transmission belt 20.

[0066] Furthermore, the transmission mechanism 2 can be a linear transmission, that is, the transmission belt 20 is arranged in a straight line, and the motor drives the transmission belt 20 to horizontally transmit the socket 22. The transmission mechanism 2 can also be a ring transmission, configured as a circular, elliptical, or quadrilateral transmission. As another embodiment, the transmission mechanism 2 may also include a turntable, on which multiple fixed grooves 21 are provided, and the feeding mechanism 3, the appearance inspection mechanism 5, the socket conductivity inspection mechanism 9, and the unloading mechanism 7 are arranged around the turntable.

[0067] like Figure 1 , 2 As shown, in a preferred embodiment of the appearance inspection mechanism 5, the appearance inspection mechanism 5 includes a support frame 55, which is connected to the inspection table 1. At least one first driving mechanism 53 is provided on the upper part of the support frame 55, and a first slide rail 54 is provided on the side of the support frame 55. The first slide rail 54 is slidably connected to at least one first slider 52. The movable end of the first driving mechanism 53 is connected to the first slider 52. The end of the first slider 52 facing the socket 22 is connected to a camera 51. The first driving mechanism 53 drives the first slider 52 to move the camera 51 up and down along the first slide rail 54.

[0068] The socket detection device in this embodiment employs a connection structure between the first slider 52 and the camera 51, enabling it to capture images of the socket 22 from different distances, thus reducing the error rate. Furthermore, this embodiment utilizes a cooperative structure between the first slide rail 54 and the first slider 52, resulting in simple maintenance, convenient operation, and high accuracy. Additionally, this embodiment employs a structure where the first drive mechanism 53 drives the first slider 52, enabling precise control of the device while providing smooth movement, and also facilitating maintenance and ensuring high safety.

[0069] It should be noted that the appearance inspection agency 5 transmits the image of the socket 22 to the controller 4. The controller 4 preprocesses the transmitted image, including resizing, grayscale conversion, and noise removal, to ensure the accuracy of subsequent processing. Then, it extracts features from the image, mainly using algorithms such as scale-invariant feature transformation and accelerated robust feature extraction to extract key points and descriptors, or using convolutional neural networks to automatically learn high-level feature representations from the image. That is, a CNN model can be trained to recognize specific types of objects or patterns, and then this model can be used to extract key features from two images. Then, for the extracted features, the similarity can be evaluated by calculating the distance between corresponding feature points between the acquired image and the qualified socket image, or if a deep learning method is used, the output feature vectors of the acquired image and the qualified socket image can be directly compared to compare the similarity. Finally, based on the judgment result, defective sockets are marked, and undefective sockets are not marked. This is the prior art in this field.

[0070] Preferably, the support frame 55 includes a vertical plate 56 and a horizontal plate 57 that are perpendicular to each other. The horizontal plate 57 is located at the end of the vertical plate 56 away from the detection table 1 and close to the socket 22. At least one first drive mechanism 53 is provided on the side of the horizontal plate 57 away from the detection table 1, and the first slide rail 54 is provided on the side of the vertical plate 56 close to the socket 22.

[0071] Preferably, this embodiment includes two first sliders 52.

[0072] Furthermore, the first slider 52 includes a first sliding plate 521, a first corner plate 522 connected to the first sliding plate 521, and a first connecting block 523 connected to the movable end of the first drive mechanism 53; the first sliding plate 521 is slidably connected to the first slide rail 54, and the end of the first sliding plate 521 away from the socket 22 is connected to the movable end of the first drive mechanism 53; the first corner plate 522 is right-angled, and the side of the first corner plate 522 away from the first drive mechanism 53 is slidably connected to the camera 51; the first connecting block 523 is abutted against the inner corner side of the first corner plate 522, one end of the first connecting block 523 is connected to the first drive mechanism 53, and the other end is connected to the camera 51. Because the first drive mechanism 53 is connected to the first sliding plate 521 and the first connecting block 523, the force applied to the first slider 52 is more balanced, thereby making the first slider 52 run smoothly and increasing the clarity of the image captured by the camera 51. Furthermore, since the first slider 52 adopts a cooperative structure of the first sliding plate 521, the first corner plate 522, and the first connecting block 523, it saves processing materials and facilitates assembly. Of course, the first connecting block 523 and the first corner plate 522 can be fitted together and separated from each other, or the first connecting block 523 and the first corner plate 522 can be fixedly connected.

[0073] Furthermore, a first limiting plate 11 is provided between the camera 51 and the first slider 52. A first transverse groove 561 is provided on the side of the support frame 55 facing the camera 51. The first transverse groove 561 is located at the lower end of the first slide rail 54. The first limiting plate 11 is inserted into the first transverse groove 561 and engages with the support frame 55. The first limiting plate 11 has multiple first through holes 111. A first connecting post 5221 is provided between the first corner plate 522 and the camera 51. A second connecting post 5231 is provided between the first connecting block 523 and the camera 51. The shapes of the first connecting post 5221 and the second connecting post 5231 match the first through holes 111. The first connecting post 5221 and the second connecting post 5231 slide through the first through holes 111 and connect to the camera 51. This allows the first slider 52 to more stably control the camera 51, reducing shaking and increasing the clarity of the image captured by the camera 51. In addition, the first limiting plate 11 limits the first slider 52 to prevent the first slider 52 from dislodging from the first slide rail 54.

[0074] Furthermore, the first corner plate 522 is provided with a second through hole 5222. The shape of the second through hole 5222 is configured to match the shape of the first connecting post 5221. The first connecting post 5221 is fixedly connected to the first corner plate 522 through the second through hole 5222, thereby enabling the camera 51 to move stably and preventing inertia from affecting the clarity of the images taken by the camera 51. Of course, the first through hole 5222 can penetrate through the first corner plate 522, or it can be a non-penetrating hole, located inside the first corner plate 522.

[0075] like Figure 1 , 3 As shown, in an optional embodiment of the socket continuity testing mechanism 9, the socket continuity testing mechanism 9 includes a fixed base 91 connected to the testing platform 1. At least one second drive mechanism 92 is provided on the upper side of the fixed base 91 away from the socket 22. The movable end of the second drive mechanism 92 is connected to the second slider 94. A second slide rail 93 is provided on the side of the fixed base 91 away from the testing platform 1. The second slide rail 93 is slidably connected to the second slider 94. At least one plug 95 is provided on the side of the second slider 94 facing the socket 22. The plug 95 includes a plurality of detection pins 954 for inserting into the socket 22 to test the continuity of the socket.

[0076] Preferably, the second slider 94 is provided with a first connecting arm 97, the first connecting arm 97 is connected to the horizontal arm 98, the first connecting arm 97 and the horizontal arm 98 are perpendicular, and the horizontal arm 98 is provided with a plurality of plugs 95.

[0077] The socket detection device in this embodiment adopts a structure in which the first connecting arm 97 and the horizontal arm 98 are perpendicular. The horizontal arm 98 remains horizontal, allowing for better cooperation with the socket 22. Furthermore, multiple plugs 95 can be arranged along the long side of the horizontal arm 98 for simultaneous insertion and removal detection of multiple sockets 22, improving detection efficiency. In addition, this embodiment employs a second drive mechanism 92, enabling precise control of the device while providing smooth movement, and also offering simple maintenance and high safety. Furthermore, this embodiment utilizes a cooperative structure of a second slide rail 93 and a second slider 94, simplifying maintenance, facilitating operation, and ensuring high accuracy.

[0078] Furthermore, a cylinder mounting plate 96 is provided on the fixed base 91, and the movable end of the second drive mechanism 92 passes through the cylinder mounting plate 96 and is connected to the second slider 94.

[0079] Furthermore, the movable end of the second drive mechanism 92 is bolted to a first clamping arm 921, which is U-shaped. The second slider 94 is inserted into the first clamping arm 921 and is detachably and fixedly connected to it. Alternatively, the first clamping arm 921 can be omitted, and the movable end of the second drive mechanism 92 can be directly connected to the second slider 94.

[0080] Preferably, the fixing base 91 is T-shaped, and two fixing bases 91 are provided. The fixing base 91 is connected to the detection table 1. Figure 3 , 4 As shown, in an optional embodiment of the plug 95, the plug 95 is installed on the upper part of the transverse arm 98, and the plug 95 is correspondingly arranged with the socket 22 for plugging and unplugging detection of the socket 22 and detection of the unobstructedness of the socket.

[0081] Preferably, the plug 95 includes a second connecting block 952, an unfolding arm 953 connected to the second connecting block 952, and detection pins 954 disposed on the unfolding arm 953; the second connecting block 952 has a U-shaped cross-section, a through groove 9522 is provided on one side of the second connecting block 952, and two protrusions 9521 are provided opposite to each other on both sides of the through groove 9522; the unfolding arm 953 includes an integrally formed second connecting arm 9531 and a third connecting arm 9532, the second connecting arm 9531 and the third connecting arm 9532 are arranged vertically, the two third connecting arms 9532 are arranged outwards and away from each other, the second connecting arm 9531 is connected to the protrusions 9521, and the third connecting arm 9532 is provided with a plurality of detection pins 954.

[0082] Furthermore, the detection pin 954 passes through the third connecting arm 9532 of the unfolding arm 953, and both ends of the detection pin 954 extend out of the third connecting arm 9532. Of course, the end of the detection pin 954 away from the socket 22 may not extend out of the third connecting arm 9532, and the end of the detection pin 954 away from the socket 22 may be located inside the third connecting arm 9532.

[0083] Furthermore, the socket 22 is provided with a guide bracket 951, which is used to guide the plug 95 into the socket 22.

[0084] like Figure 3-4As shown, in a preferred embodiment where the plug 93 mates with the socket 22, the second drive mechanism 92 drives the second slider 94 to slide along the second slide rail 93 toward the socket 22. The plug 95 on the second slider 94 corresponds to the socket 22. If the detection pin 954 is inserted into the socket 22, the socket 22 is unobstructed; if the detection pin 954 cannot be inserted into the socket 22, the socket 22 is not unobstructed. The socket continuity detection mechanism 9 transmits the information about whether the socket 22 is unobstructed or not to the controller 4.

[0085] Furthermore, in one optional embodiment for detecting the patency of the socket 22, the detection pin 954 is slidably engaged with the plug 95, and an elastic component is provided between the detection pin 954 and the plug 95. When the detection pin 954 is subjected to force, it can slide relative to the plug 95 and compress the elastic component. When the detection pin 954 cannot be inserted into the socket 22, it experiences a reverse force from the socket, causing one end of the detection pin 954 near the socket 22 to move towards the plug 95. Based on the position of the detection pin 954, it is determined that the socket 22 is not patency-free, and this information is transmitted to the controller 4. The socket patency detection mechanism includes a first displacement detection mechanism for detecting the relative movement distance between the detection pin 954 and the plug 95. The first displacement detection mechanism includes a sensor, microswitch, or electronic measuring scale, etc., with a simple and compact overall structure and high detection accuracy.

[0086] For example, a sensor is provided on the plug 95 to sense the position of the detection pin 954. The sensor is connected to the controller 4. The sensor can be an infrared sensor or other sensors. Detecting the pin 954's movement relative to the plug 95 due to its inability to be inserted into the socket 22 triggers the sensor. When the infrared sensor detects the pin 954, it transmits a signal to the controller 4, indicating that the socket is not open. Alternatively, a microswitch is provided on the plug 95, connected to the controller 4. Detecting the pin 954's movement relative to the plug 95 due to its inability to be inserted into the socket 22 triggers the microswitch to switch states, transmitting a signal to the controller 4, indicating that the socket is not open. Obviously, the first displacement detection mechanism can also adopt other solutions.

[0087] Specifically, the detection pin 954 has a radially arranged annular flange, the third connecting arm 9532 has a hollow internal structure, and the inner wall surface of the third connecting arm 9532 facing the socket 22 has a protruding post, which is correspondingly arranged with the annular flange. An elastic member is arranged between the protruding post and the annular flange. The elastic member is sleeved on the protruding post and the detection pin 954 and is in close contact with both the inner wall surface of the third connecting arm 9532 and the annular flange. When the detection pin 954 can be inserted into the socket 22, the elastic member does not retract (or retracts slightly); when the detection pin 954 cannot be inserted into the socket 22, the elastic member retracts, and the end of the detection pin 954 near the socket 22 moves toward the plug 95. Based on the movement distance of the detection pin 954, it is determined that the socket 22 is not clear and the information is transmitted to the controller 4.

[0088] In another optional embodiment for detecting the patency of the socket 22, the detection pin 954 and the plug 95 are fixedly connected, the unfolding arm 953 is slidably engaged with the second connecting block 952, and an elastic component is provided between the unfolding arm 953 and the second connecting block 952. The unfolding arm 953, when subjected to force, can slide relative to the second connecting block 952 and compress the elastic component. The patency detection mechanism includes a second displacement detection mechanism for detecting the relative movement distance between the unfolding arm 953 and the second connecting block 952. The second displacement detection mechanism includes a sensor, a microswitch, or an electronic measuring ruler, etc., which will not be described in detail here. When the plug 95 cannot be inserted into the socket 22, the socket 22 applies a reverse force to the plug 95, driving the unfolding arm 953 to remain stationary relative to the socket 22, while the second connecting block 952 moves towards the socket 22. Specifically, the connection between the protrusion 9521 and the second connecting arm 9531 is a hollow structure. A protruding post is provided on the inner wall of the hollow structure near the socket 22. A boss is provided on the third connecting arm 9532 corresponding to the protruding post. An elastic component is provided between the protruding post and the boss. The elastic component is in close cooperation with the protruding post and the boss. When the detection pin 954 can be inserted into the socket 22, the second connecting block 952 and the unfolding arm 953 remain relatively stationary. When the detection pin 954 cannot be inserted into the socket 22, the second connecting block 952 and the unfolding arm 953 slide relative to each other. The second connecting block 952 moves towards the socket 22, triggering the second displacement detection mechanism, thereby determining that the socket 22 is not working properly and transmitting the information to the controller 4.

[0089] In another optional embodiment for detecting the patency of the socket 22, the detection pin 954 includes a sleeve 9541 and a pin 9542. The sleeve 9541 is fixed to the plug 95, and the pin 9542 is slidably disposed within the sleeve 9541. An elastic component is provided between the pin 9542 and the sleeve 9541. A sleeve 9543 can be provided at the head of the pin 9542 as a pushing part. The patency detection mechanism includes a third displacement detection mechanism for detecting the relative movement distance between the sleeve 9541 and the pin 9542. When the pin of the detection pin 954 can be inserted into the socket 22, the pin 9542 and the sleeve 9543 remain relatively stationary; when the pin 9542 cannot be inserted into the socket 22, the compression elastic component of the pin 9542 slides relative to the sleeve 9543. This sliding of the detection pin 9542 can trigger the third displacement detection mechanism (slight movement may not trigger the third displacement detection mechanism), thereby determining that the socket 22 is not functioning properly and transmitting the information to the controller 4. Preferably, the third displacement detection mechanism is located inside the sleeve 9541. The second displacement detection mechanism includes a sensor, a microswitch, or an electronic measuring ruler, etc.

Alternatively, the fourth hydraulic cylinder can be a double-rod hydraulic cylinder, that is, the fourth hydraulic cylinder has two movable ends, which are respectively connected to the first robotic arm 751 and the second robotic arm 752, driving the first robotic arm 751 and the second robotic arm 752 to open or retract simultaneously, thereby realizing the grasping or placing of the robotic arm 75. This is prior art in the field.

[0096] As another embodiment of the feeding mechanism 7, the feeding mechanism 7 includes multiple sets of feeding cylinders and feeding push rods connected to the feeding cylinders. The feeding cylinders drive the feeding push rods to push the socket 22 down from the transmission mechanism 2 and into the corresponding feeding channel 30.
