DETAILED DESCRIPTION

[0051] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0052] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0053] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0054] Safety testing is to conduct a series of safety performance tests by simulating the possible use of electrical products by users, mainly emphasizing the safety protection of users, so that we can operate electrical products conveniently without being harmed by them. Assuming that the electrical product loses some or all of its functions during use and does not cause danger to the user, we judge that the safety design of the product is qualified.

[0055] The safety test items mainly include eight test items: AC withstand voltage, DC withstand voltage, insulation resistance, ground resistance, leakage current, load power, low voltage starting, and short circuit test.

[0056] Traditional safety testing uses manual power cord plugging, and the operation process consumes a lot of workers' time and energy. At the same time, since the safety instrument carries high voltage electricity, manual operation has certain safety risks. The existing safety tester plug-in device has a fixed position, so it is only applicable to a single model of product. Different models of products have different positions of power holes and cannot achieve compatible plug-in. At the same time, the same model of products may have inaccurate power hole positions due to processing errors and assembly errors, which may also lead to the inability to effectively achieve plug-in. Therefore, the existing technology has defects in plug-in efficiency, plug-in safety and plug-in effectiveness.

[0057] In order to solve the above-mentioned problems existing in the prior art, the present application provides a safety testing mechanism, which solves the problems of high manual labor intensity and safety risks by adopting a plug-in robot to plug in test lines. At the same time, the test line plug-in and backplane grounding operations are both positioned through a visual inspection mechanism, which can improve the plug-in efficiency while increasing the versatility of the safety testing mechanism.

[0058] Reference Figure 1-10 As shown, the embodiment of the present application provides a safety test mechanism that can realize the automatic transportation, identification and plug-in operation of the product, which includes:

[0059] The conveying device 100 is used to convey the product to be tested to a designated location and to support the product to be tested so that the product to be tested can be subjected to safety testing thereon;

[0060] The plugging robot 200 is disposed on one side of the conveying device 100 and is used for plugging the test wires;

[0061] The plug-in robot 200 includes a first visual detection mechanism 225 and a power plug-in assembly 224. The first visual detection mechanism 225 is used to detect the position of the power hole of the product to be tested. After the plug-in robot 200 determines the position of the power hole of the product to be tested through the first visual detection mechanism 225, it controls the power plug-in assembly 224 to plug the test line;

[0062] The backplane grounding mechanism 300 includes a second visual detection mechanism 313 and a grounding piece 314. The second visual detection mechanism 313 is used to identify the product position. After the backplane grounding mechanism 300 determines the product position through the second visual detection mechanism 313, it controls the grounding piece 314 to perform a grounding operation.

[0063] In this application, by setting up a first visual inspection mechanism 225 for use with the power plug assembly 224, and setting up a second visual inspection mechanism 313 in the backplane grounding mechanism 300, the plug-in position can be determined by the first visual inspection mechanism 225 and the second visual inspection mechanism 313, so as to avoid plug-in failure caused by inaccurate alignment, and realize the full automation of safety test plug-in. Compared with being able to plug in only at a predetermined position, this solution can avoid the problem of inaccurate alignment caused by product processing errors and failure to plug in when performing safety tests on products of the same model. At the same time, this solution has stronger compatibility and can automatically adapt to safety tests of products of different models and with plug holes in different positions.

[0064] For example, in some products, the wire plug hole is located at the bottom of the back panel and needs to be plugged in from the bottom, while in some products, the wire plug hole is located on the side and needs to be plugged in from the side. The plugging mechanism in the prior art can only perform plugging and unplugging operations at a specific position. When the plugging direction or plugging position changes, the wire plug hole cannot be aligned and plugging cannot be performed.

[0065] In the present application, after the product is moved as a whole to the preset position, the position of the wire socket is obtained by the first visual inspection mechanism 225, and the power plug assembly 224 is controlled to accurately perform the plugging operation based on the obtained position information. The back panel is imaged by the second visual inspection mechanism 313 to obtain the specific position information of the back panel. The grounding operation is controlled by the grounding component 314 based on the back panel position information obtained by the second visual inspection mechanism 313, which can ensure that the grounding component 314 can effectively contact the specific position on the back panel, thereby effectively achieving grounding.

[0066] It should be pointed out that the visual inspection mechanism refers to a mechanism that uses machine vision technology to inspect products. It is a technology that uses computers to process and analyze images to obtain information. The visual inspection mechanism can inspect the appearance, size, position, defects, etc. of the product. The use of a visual inspection mechanism for position detection belongs to the prior art, and its specific structure and implementation scheme are not described in detail in this application.

[0067] The conveying device 100 uses a conveying line that can transport and position the product to be tested. Specifically, it can adopt an existing mature conveying line structure, which is not limited in this application.

[0068] For example, refer to Figure 3-7As shown, the plug-in robot 200 provided in the embodiment of the present application also includes a robot body 210 and a mounting frame 220 , the mounting frame 220 is fixedly installed on the robot body 210 , and the power plug-in assembly 224 and the first visual detection mechanism 225 are both installed on the mounting frame 220 .

[0069] The robot body 210 is used to adjust the plugging direction and position, and the mounting frame 220 is used to install the power plug assembly 224 and the first visual detection mechanism 225. The robot body 210 can adopt a general robot structure in the prior art, such as a multi-joint robot of ABB, and according to the application scenario of the plugging robot 200 of the present application, the corresponding mounting frame 220 is set to install the power plug and the first visual detection mechanism 225, which can reduce the development cost of the equipment and ensure the stability and reliability of the equipment.

[0070] Specifically, refer to Figure 5-7 As shown, the mounting frame 220 in the embodiment of the present application includes a connecting shaft 221 and three brackets 222, the connecting shaft 221 is fixedly connected to the robot body 210 through a flange 223, the three brackets 222 are evenly distributed on the circumference of the connecting shaft 221 in a circumferential direction with the axis of the connecting shaft 221 as the center, and the first visual detection mechanism 225 and the two groups of the power cord assemblies 224 are respectively installed on one of the brackets 222.

[0071] Three brackets 222 are used to install the first visual inspection mechanism 225 and two power plug assemblies 224, which can perform visual inspection and positioning while providing spare power plug assemblies 224. When one of the power plug assemblies 224 fails, another power plug assembly 224 can be used for plugging in to successfully complete the safety test.

[0072] Specifically, one end of the connecting shaft 221 is fixedly connected to the robot body 210, three brackets 222 are connected to the end of the connecting shaft 221 away from the robot body 210, and the detection direction of the first visual detection mechanism 225 and the plugging direction of the two groups of power cord assemblies 224 both extend along the axial direction of the connecting shaft 221 in a direction away from the robot body 210.

[0073] Furthermore, three brackets 222 extend outward from one end of the connecting shaft 221 away from the robot body 210, and the three brackets 222 are evenly distributed on the circumference of the connecting shaft 221 in a circumferential direction with the axis of the connecting shaft 221 as the center, two of the brackets 222 are installed with the power plug assembly 224, and the other bracket 222 is installed with the first visual detection mechanism 225.

[0074] In the present embodiment, three brackets 222 are evenly distributed on the periphery of the connecting shaft 221 in the circumferential direction with the axis of the connecting shaft 221 as the center, and the plug-in directions are all extended along the axis of the connecting shaft 221 in the direction away from the robot body 210, so that when any power plug assembly 224 is used to plug into the power port of the product to be tested, the remaining brackets 222 are not located in the plug-in plane, that is, the plug-in process of the power plug assembly 224 being plugged in is not interfered with.

[0075] In the embodiment of the present application, the power plug assembly 224 is connected to the bracket 222 and is extended relative to the connecting shaft 221, so that the power plug assembly 224 can be plugged in and out of the power port of the product to be tested for safety testing. It is understandable that the bracket 222 can be extended relative to the connecting shaft 221 to achieve the bracket 222 driving the power plug assembly 224 to extend relative to the connecting shaft 221. Of course, the power plug assembly 224 can also be extended by setting an extension portion on a part of the bracket 222.

[0076] During the working process, the robot body 210 moves the fixing frame to the vicinity of the product to be tested, and after aligning the power plug assembly 224 with the power hole of the product to be tested, the power plug assembly 224 extends relative to the connecting shaft 221 to be inserted into the power hole for safety testing. After the test is completed, the power plug assembly 224 retracts relative to the connecting shaft 221 to exit the power hole, thereby waiting for the next safety test.

[0077] It should be pointed out that the structure in which the above-mentioned mounting frame 220 includes three brackets 222 is not a limitation of the present application. In other embodiments, a technical solution with only two brackets 222, one for installing the first visual detection mechanism 225 and the other for installing the power cord assembly 224, can also be adopted.

[0078] Similarly, the arrangement of the three brackets 222 is not limited to being evenly distributed. In specific use, those skilled in the art can reasonably select the arrangement of the brackets 222 according to actual needs.

[0079] A specific structure for realizing the extension and retraction of the power plug assembly 224 is described below. Figure 5-6 As shown, the power cord assembly 224 includes a main body 2241, a slide rod 2242 and a push head 2243, one end of the main body 2241 is connected to the bracket 222, one end of the slide rod 2242 is connected to an end of the main body 2241 away from the bracket 222, the push head 2243 is connected to the slide rod 2242, and the push head 2243 is retracted relative to the main body 2241 through the slide rod 2242, and the power cord plug 400 is fixed to the push head 2243.

[0080] In the present application, the body 2241 can be in the shape of a plate, a block or a rod to provide support for the push head 2243, and the two ends of the slide bar 2242 are respectively connected to the body 2241 and the push head 2243, so that the push head 2243 can be extended and retracted relative to the body 2241, so as to be close to or away from the body 2241. The power cord plug 400 is fixed to the push head 2243, and the push head 2243 can drive the power cord plug 400 to extend and retract relative to the body 2241 to plug and unplug the power hole of the product to be tested. The push head 2243 is provided with a mounting hole, and one end of the power cord plug 400 passes through the mounting hole, so that part of the power cord plug 400 protrudes from the push head 2243 to be inserted into the power hole. The connection method between the power cord plug 400 and the push head 2243 can be screw connection, snap connection or bonding, etc., which is not limited here.

[0081] Optionally, two sliding rods 2242 extending in parallel are provided on the bracket 222 , the two sliding rods 2242 are arranged at an interval, and the two sliding rods 2242 are respectively connected to the pushing heads 2243 to improve the connection stability.

[0082] Furthermore, the power cord plug 400 includes a plug connector 410 and a wire body 420 connected to each other, and the plug connector 410 is fixed to the push head 2243 to ensure that the wires connected to the power cord plug 400 can remain smooth during the extension and movement of the power cord plug 400. Figure 6 As shown, in an optional embodiment of the present application, a receiving groove 2244 is provided in the body 2241, and the receiving groove 2244 extends from an end adjacent to the push head 2243 toward an end away from the push head 2243, and a portion of the wire body 420 is received and limited in the receiving groove 2244 and can slide in the receiving groove 2244 in the extension direction of the wire. Providing the receiving groove 2244 for receiving the wire body 420 can ensure that the wire body 420 is neat and not messy, and can achieve smooth sliding of the power cord plug 400.

[0083] In this embodiment, since the receiving groove 2244 extends in the length direction of the body 2241, after the plug connector 410 is fixed to the push head 2243, the wire body 420 connected to the plug connector 410 can be accommodated in the receiving groove 2244, so that the extension direction of the wire body 420 is consistent with the plug-in direction of the plug connector 410, and the plug-in stability is maintained. In this way, part of the wire body 420 adjacent to the plug connector 410 is accommodated in the receiving groove 2244 to prevent the wire body 420 from shaking randomly and causing the plug connector 410 to loosen. It should be noted that the wire body 420 can slide in the extension direction of the receiving groove 2244, so that when the plug connector 410 moves with the push head 2243, the wire body 420 can move relative to the body 2241, thereby avoiding the situation of pulling. Exemplarily, the receiving groove 2244 is a dovetail groove, and the wire body 420 penetrates from one end of the receiving groove 2244, and the other end penetrates and connects to the plug connector 410.

[0084] Optionally, refer to Figure 6 As shown, the main body 2241 is provided with a photoelectric sensor 2245 for detecting whether the plug is in place. The photoelectric sensor 2245 is used to detect whether the power cord plug 400 is plugged in and whether it is plugged in correctly. When plugging in, if the plug is not plugged in properly or plugged in obliquely, causing the photoelectric sensor 2245 to not sense the position, the device will alarm, the safety tester will not be powered on, and the visual detection positioning and plugging operation will be re-performed until the photoelectric sensor 2245 senses the position.

[0085] Preferably, the photoelectric sensor 2245 described in the embodiment of the present application adopts a slot-type photoelectric sensor 2245. The slot-type photoelectric sensor 2245 is a type of photoelectric sensor 2245, which is characterized in that the transmitter and the receiver are installed in a slot. When the detected object passes through the slot, the light is blocked and the photoelectric sensor 2245 outputs a switch signal. The specific installation structure and implementation method of the slot-type photoelectric sensor 2245 used for plug-in detection in the present application belong to the prior art. Those skilled in the art can make a reasonable choice according to the actual structure. This application does not describe it in detail.

[0086] In some embodiments of the present application, the positioning movement of the power cord plug 400 can be completely realized by relying on the freedom of movement and movement formation of the robot body 210, while in other embodiments, the movement of the power cord plug 400 in certain directions can also be realized through other structures.

[0087] Specifically, refer to Figure 1-3 As shown, in an optional embodiment of the present application, the safety testing mechanism further includes a first track 500 , and the first track 500 is disposed on one side of the conveying device 100 , and the wire insertion robot 200 is movably disposed on the first track 500 .

[0088] It is understandable that the plugging robot 200 can move on the first track 500 to adjust the position of the plugging robot 200 and timely adjust the relative position of the plugging robot 200 and the product to be tested. Exemplarily, the first track 500 can enable the plugging robot 200 to move in the direction of approaching and moving away from the conveying device 100, so as to remove the plugging robot 200 for maintenance operations, etc.

[0089] Of course, in an optional embodiment of the present application, the extension direction of the first track 500 may be consistent with the extension direction of the conveying device 100. The first track 500 can enable the wire-inserting robot 200 to move in a direction parallel to the conveying device 100, thereby adjusting the relative position of the wire-inserting robot 200 and the product to be tested. For example, if the first visual inspection mechanism 225 captures the product position information and determines that the position of the wire-inserting robot 200 needs to be adjusted, the first track 500 can be used for rapid adjustment. This solution is more suitable for position adjustment in a larger range.

[0090] It should be noted that the consistent direction here means that the extension direction of the first track 500 is parallel or nearly parallel to the extension direction of the conveying device 100, so as to ensure that when the product to be tested moves on the conveying device 100, the wire-insertion robot 200 can timely adjust its relative position with the product to be tested on the first track 500.

[0091] Further, see Figure 8-10 As shown, in an optional embodiment of the present application, the backplane grounding mechanism 300 also includes a driving component 310, and the driving component 310 is arranged on one side of the conveying device 100; the grounding member 314 is arranged on the driving component 310, and the driving component 310 is used to drive the grounding member 314 to approach or move away from the conveying device 100, so that the grounding member 314 docks with or detaches from the product to be tested.

[0092] In this embodiment, the driving component 310 drives the grounding member 314 to dock with the product to be tested, so that the product to be tested is grounded during the safety test. Exemplarily, the grounding member 314 is movably arranged above the conveying device 100, so when the product to be tested is conveyed to the specified position on the conveying device 100, the driving member grounding member 314 moves to the top of the product to be tested, and then drives the grounding member 314 down to contact with the product to be tested to complete the grounding. After the safety test is completed, the driving component 310 drives the grounding member 314 to rise, so as to perform the safety test of the next product later. Optionally, the grounding member 314 is a grounding pin 3142, so as to contact with the product to be tested and detach in time.

[0093] A spring 3141 is provided on the outside of the grounding pin 3142. When the grounding pin 3142 is in the grounding position, the spring 3141 is compressed, driving the grounding pin 3142 to have a movement tendency toward the product, so that the grounding pin 3142 can fit tightly on the product to achieve good grounding. The spring 3141 is provided to provide a grounding preload, so that the driving component 310 can drive the grounding pin 3142 to move more flexibly, thereby avoiding the rigid structure of the grounding pin 3142 having poor contact with the product and failing to achieve the grounding effect, and the grounding pin 3142 having excessive collision with the product due to excessive descent distance, thereby causing damage to the grounding pin 3142 or the product.

[0094] It can be understood that the grounding operation of the grounding component 314 refers to electrically connecting the grounding component 314 to the metal backplane of the product to be tested. The specific grounding operation can be to make the grounding component 314 directly contact the metal backplane, or to make the grounding component 314 contact the metal wall-mounted bracket 222 directly connected to the metal backplane.

[0095] Typically, the grounding operation uses a solution in which the grounding piece 314 is connected to the metal wall-mounted bracket 222. This method can further avoid damage to the product back panel and affect the product appearance.

[0096] Next, we will combine Figure 8 , 9 The driving component 310 described in the embodiment of the present application is illustrated as an example. The driving component 310 includes a Y-axis module 311 and a Z-axis module 312. The Z-axis module 312 is arranged on the Y-axis module 311, and the grounding member 314 is arranged on the Z-axis module 312. The Y-axis module 311 is used to drive the Z-axis module 312 to move in the Y direction, and the Z-axis module 312 is used to drive the grounding member 314 to move in the Z direction.

[0097] In this embodiment, the Z-direction module 312 is used to control the grounding member 314 to move up and down, and the Y-direction module 311 is used to drive the Z-direction module 312 to move horizontally.

[0098] Specifically, refer to Figure 8 As shown, in this embodiment, the Z direction is the vertical direction, that is, the gravity direction, that is, the grounding piece 314 is connected or separated from the product to be tested by rising and falling to adapt to the situation where the grounding part of the product to be tested is located at the top. The Y direction is the horizontal direction perpendicular to the Z direction, so that by adjusting the relative position of the grounding piece 314 and the product to be tested in the Y direction, the grounding piece 314 can correspond to the grounding part of the product to be tested.

[0099] It is understandable that the vertical direction of the Z direction is not a limitation of the present application. In other embodiments, the Z direction may also be a horizontal direction, that is, the rectangular coordinate system defined by the Y direction and the Z direction is located in the horizontal plane. The grounding member 314 adjusts the docking position by translating along the Y direction, and is connected or separated from the product to be tested by telescoping along the Z direction to adapt to the situation where the grounding part of the product to be tested is located on the side. The Y direction and the Z direction are not specifically limited here, as long as the grounding member 314 can be moved in two dimensions to facilitate the adjustment of the relative position of the grounding member 314 and the product to be tested.

[0100] Optional, see Figure 8 , 9 As shown, the backplane grounding mechanism further includes a second track 600 , the second track 600 is disposed on one side of the conveying device 100 , and the driving assembly 310 is movably disposed on the second track 600 .

[0101] The second track 600 can increase the freedom of movement of the grounding component. In the present application, the driving component 310 can move on the second track 600, that is, the grounding member 314 moves along the second track 600 with the driving component 310, so as to adjust the position of the grounding member 314.

[0102] In an optional embodiment of the present application, an extension direction of the second track 600 is consistent with an extension direction of the conveying device 100 .

[0103] It should be noted that the consistency here means that the extension direction of the second track 600 is parallel or nearly parallel to the extension direction of the conveying device 100, so as to ensure that when the product to be tested moves on the conveying device 100, the driving component 310 can timely adjust its relative position with the product to be tested on the second track 600.

[0104] Exemplarily, the second track 600 can enable the driving assembly 310 to move in a direction parallel to the conveying device 100 , thereby adjusting the relative position of the grounding member 314 and the product to be tested.

[0105] It should be pointed out that the fact that the second track 600 enables the drive assembly 310 to move in a direction parallel to the conveying device 100 is not a limitation of the present application. In other embodiments, the second track 600 can also enable the drive assembly 310 to move in a direction perpendicular to the conveying device 100, so as to move the drive assembly 310 a certain distance away from the conveying device 100 for maintenance operations, etc.

[0106] Reference Figure 1 , 2As shown, in one embodiment of the present application, the second track 600 is located on one side of the conveying device 100, and the first track 500 is located on the other side of the conveying device 100, that is, the first track 500 and the second track 600 are located on opposite sides of the conveying device 100. Arranging the first track 500 and the second track 600 on both sides of the conveying device 100 can reasonably allocate the installation positions to prevent the two from interfering with each other.

[0107] In the embodiment of the present application, the second visual detection mechanism 313 is disposed on the driving assembly 310 , and the shooting direction of the second visual detection mechanism 313 is the same as the extension and retraction direction of the grounding member 314 .

[0108] Specifically, refer to Figure 8 , 9 As shown, in this embodiment, the second visual inspection mechanism 313 is disposed on the Y-axis module 311 and can move with the movement of the Y-axis module 311 , that is, the second visual inspection mechanism 313 is synchronized with the movement of the grounding member 314 during the process of adjusting the alignment.

[0109] During operation, the second visual inspection mechanism 313 takes a photo to locate the product to be tested, and after identifying the position, controls the grounding piece 314 to be inserted into the product to be tested so that the grounding piece 314 contacts the back plate of the product to be tested or the metal wall bracket 222. When the first visual inspection mechanism does not take a photo to identify the position of the product to be tested, an alarm may be issued and the grounding piece 314 may be stopped from docking.

[0110] It can be understood that the first visual inspection mechanism 225 and the second visual inspection mechanism 313 simultaneously position the product to be tested, with high positioning accuracy and low misjudgment rate, thereby improving the accuracy of wire insertion during safety testing of the product to be tested.

[0111] The first visual inspection mechanism 225 and the second visual inspection mechanism 313 are both visual inspection mechanisms. The visual inspection mechanism refers to a device that uses machine vision technology to inspect workpieces, and is mainly composed of the following parts:

[0112] Light source: used to illuminate the workpiece so that the surface features of the workpiece can be captured by the camera.

[0113] Camera: used to collect image information of the workpiece.

[0114] Image processor: used to process the collected images and extract the feature information of the workpiece.

[0115] Controller: used to control the operation of light source, camera and image processor.

[0116] It should be pointed out that the composition of the above-mentioned visual detection mechanism does not serve as a limitation to the present application. Those skilled in the art may adopt the corresponding visual detection mechanism composition according to actual needs as long as the visual detection effect described in this solution can be achieved.

[0117] It is understandable that the safety test mechanism delivered by the embodiment of the present application also includes a safety tester and a control system. The control system connects and controls the safety tester, the conveying device 100, the plugging robot 200, and the backplane grounding mechanism 300 to achieve safety testing as a whole. Among them, the safety tester is an existing mature product, and the embodiment of the present application does not cite it as an example. The control system and the connection and control scheme of the above-mentioned various parts belong to conventional technical means in the field. Those skilled in the art can choose according to actual conditions, and this application does not elaborate on its specific implementation scheme.
