Description

Technical Field

[0001] The present invention relates to the technical field of electronic equipment detection, and in particular to a rotary joint group, an electric rail joint, a detection line and a detection method. Background Art

[0002] Electronic equipment needs to be powered on and tested before leaving the factory. That is, the assembled electronic equipment to be shipped needs to be powered on, and each function to be tested on the electronic equipment after powering on is tested in turn to ensure that the circuit connection quality of the electronic equipment and the assembly quality of electronic components meet the factory requirements.

[0003] In the existing technology, in order to meet the testing needs of large quantities of electronic products, the most common testing method is: setting up an assembly line for transporting electronic equipment carriers and an AC rail for power supply, manually placing the carrier on the assembly line, placing the connector on the rail, and connecting the carrier and the connector through wires to power the carrier, so that the electronic equipment installed on the carrier can be tested. During this process, the carrier pulls the connector to move on the rail. When it reaches the end of the assembly line and the rail, the carrier and the connector are manually removed and recycled.

[0004] In the process of realizing this application, the inventors realized that there are at least the following problems in the prior art: the carrier is connected to the connector through an ordinary plug, such as a two-phase plug or a three-phase plug, and the carrier pulls the connector to move the connector on the power rail. During this process, it is easy for the wires to become tangled or the plug to fall off, which requires manual maintenance. Moreover, since the connector and the carrier are both unidirectional, they need to be manually put on and taken off the line and recycled, which is cumbersome to operate, leading to congestion on the production line, seriously affecting the detection efficiency and greatly increasing the labor cost. Summary of the Invention

[0005] In view of the above shortcomings of the prior art, the purpose of the present invention is to provide a rotary joint group, a power rail joint, a detection line and a detection method to solve the problem in the prior art that electronic equipment is prone to wire tangling, plug falling off, etc. during power-on detection, requiring manual maintenance, and manual completion of online, offline and recycling, which is cumbersome to operate, leading to congestion of the production line, seriously affecting detection efficiency, and greatly increasing labor costs.

[0006] To achieve the above objectives and other related objectives, in a first aspect, the present application provides a rotary joint assembly, comprising:

[0007] A socket portion, wherein a conductive area is provided on the socket portion, and the conductive area includes a first conductive area for connecting a neutral wire and a second conductive area for connecting a live wire;

[0008] A plug portion, wherein the plug portion is provided with a first pin and a second pin;

[0009] The plug portion rotates around the first axis of the rotary joint assembly and can switch between two plug-in states:

[0010] In a first plugging state, the first pin contacts the first conductive area, and the second pin contacts the second conductive area;

[0011] In the second plugging state, the first plug pin contacts the second conductive area, and the second plug pin contacts the first conductive area.

[0012] With this structure, a first conductive area and a second conductive area are set on the socket part, so that the plug part has two plug-in states that can be switched with each other when it rotates relative to the socket part. By switching between the two plug-in states, the switching of the two plug-in states is realized. It can adjust its own plug-in state while maintaining power, effectively avoiding problems such as wire tangling and plug falling off during connection, reducing the need for manual maintenance, and greatly improving the convenience and reliability of connection.

[0013] Furthermore, the conductive area also includes a grounding area, and the plug portion is also provided with a third pin for contacting the grounding area. The grounding area and the third pin are located on the first axis. The provision of the third pin and the grounding area is conducive to improving the safety of the rotary joint group and avoiding safety accidents caused by unexpected situations such as circuit instability and leakage.

[0014] Furthermore, a spacer is provided between the first conductive area and the second conductive area, and when the first plug pin and / or the second plug pin crosses the spacer, the plugging state is switched.

[0015] Furthermore, the first pin and the second pin are connected to the plug portion via an elastic element. In normal state, the first pin and the second pin maintain contact with the conductive area under the action of the elastic element. When the plugging state is switched, the elastic element is compressed to allow the first pin and the second pin to pass over the spacer area. With this structure, on the one hand, the first pin and the second pin can easily pass over the spacer area when the plugging state is switched. On the other hand, the first pin and the second pin are pressed by the elastic element, which is conducive to maintaining the fit quality with the first conductive area and the second conductive area.

[0016] Furthermore, the first conductive area and the second conductive area are grooves distributed along a circular arc, the first pin and the second pin are configured as conductive spheres that match the grooves, and the elastic element is a spring.

[0017] Furthermore, a transition surface is provided between the groove and the spacer area for guiding the first pin and the second pin when they pass through the spacer area. This structure is beneficial to improving the smoothness of switching between plug-in states, avoiding jamming, and reducing wear.

[0018] Furthermore, the first plug pin and the second plug pin are arranged on the end surface of the plug part, and the conductive area is arranged opposite to the first plug pin and the second plug pin on the plug part.

[0019] Furthermore, a limited locking structure is provided on the rotary joint assembly for limiting the movement of the plug portion in the direction of the first axis.

[0020] In a second aspect, the present application provides a power rail connector, comprising the above-mentioned rotary connector group, and a movable connection component located on the socket portion, wherein the movable connection component comprises a roller that cooperates with the power rail.

[0021] With this structure, when the rail connector moves along the rail, it can adjust its own plug-in state while maintaining power, effectively avoiding problems such as wire tangling and plug falling off during connection, reducing the need for manual maintenance, and greatly improving the convenience and reliability of connection.

[0022] In a third aspect, the present application provides a detection line, comprising an electric rail, and a conveying line close to the electric rail and used to convey a carrier, wherein the electric rail is annular and is provided with at least one group of the above-mentioned rotary joint groups, and the rotary joint group moves in a circular motion along the electric rail.

[0023] By adopting this structure, a ring-shaped power rail is set up, and a rotary joint group is set on the power rail, so that the rotary joint group can move in a circular motion on the power rail. The rotary joint group can remain energized without the need to re-take it out or re-plug it. This effectively improves the shortcoming of the existing technology that the joint needs to be manually taken out and placed from the power rail, greatly improves the detection efficiency of electronic equipment on the detection line, and reduces the labor cost of electronic equipment detection.

[0024] Furthermore, the detection line also includes a return line close to the power rail and used for returning the carrier. During the process of the carrier moving from the conveying line to the return line, the carrier remains connected to the rotary joint group.

[0025] Furthermore, the detection line also includes a lifting device arranged at both ends of the conveying line and the return line, the return line and the conveying line form a circulation path through the lifting device, and the carrier circulates along with the rotary joint group in the circulation path.

[0026] In a fourth aspect, the present application provides an electronic device detection method, applicable to an electronic device detection line in the above-mentioned solution, comprising:

[0027] Place the carrier at the entrance of the conveyor line, and drag the rail connector to move along the conveyor line on the rail;

[0028] When the carrier moves on the conveyor line, electronic equipment is loaded and unloaded on the carrier for testing;

[0029] When the carrier moves to the outlet end of the conveyor line, it enters the inlet end of the return line through the lifting device. During this process, the moving direction of the carrier changes 180 degrees, and the electric rail connector completes the switching of the plug-in state once;

[0030] When the carrier moves to the outlet end of the return line, it enters the inlet end of the conveyor line through the lifting device. During this process, the moving direction of the carrier changes 180°, and the electric rail connector completes the switching of the plug-in state once.

[0031] As described above, a rotary joint assembly, electric rail joint, detection line and detection method have at least the following beneficial effects:

[0032] 1. By providing a first conductive area and a second conductive area on the socket, the plug can be switched between two plug-in states when it rotates relative to the socket. The plug rotates relative to the socket to switch between the two plug-in states. The plug can adjust its own plug-in state while maintaining power, effectively avoiding problems such as wire tangling and plug falling off, reducing the need for manual maintenance and greatly improving the convenience and reliability of the connection.

[0033] 2. By setting up a ring-shaped power rail and a rotary joint group on the power rail, the rotary joint group can be made to circulate on the power rail. The rotary joint group can be kept powered on without having to be re-taken and re-plugged. This effectively improves the disadvantage of the existing technology that the joint needs to be manually taken and placed from the power rail, greatly improves the detection efficiency of electronic equipment on the detection line, and reduces the labor cost of electronic equipment detection.

[0047] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0048] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention. Therefore, they have no substantial technical significance. Any modification of the structure, change in the proportional relationship or adjustment of the size should still fall within the scope of the technical content disclosed by the present invention without affecting the efficacy and purpose that can be achieved by the present invention. At the same time, terms such as "upper", "lower", "left", "right", "middle", "first", "second", etc. quoted in this specification are only for the convenience of description and are not used to limit the scope of the implementation of the present invention. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0049] The present application provides a rotary joint assembly that can be used in AC circuit connection processes in various scenarios, including but not limited to power-on detection of electronic devices. Its specific implementation methods may include but are not limited to power rail connectors 1, electrical connectors, sockets, etc.

[0050] In one embodiment, see Figures 1-4 The present application provides a specific application scheme of a power rail connector 1, namely, a power rail connector 1 using a rotary connector group, including a socket part 11 and a plug part 12. The socket part 11 is used to be directly installed on the power rail 2 for power supply, and the plug part 12 is used to be plugged into the socket part 11 and connected to the electronic device to be tested through methods such as but not limited to wire connection to provide voltage to the electronic device. It should be understood that the power rail 2 here generally refers to a device used in industrial production and related fields to temporarily provide AC voltage to electronic equipment for power-on detection or a device or equipment with similar functions. The power rail 2 includes a rail 21 connected to the neutral wire and the live wire of the high voltage respectively. By installing the socket part 11 on the power rail 2 and connecting it to the rail 21 connected to the neutral wire or the live wire, the socket part 11 can be powered on; the electronic devices here include but are not limited to computers, tablet computers, display screens, and other devices that can be connected to a power source for use and detection.

[0051] The socket portion 11 is provided with a first conductive area 111 for connecting the neutral wire and a second conductive area 112 for connecting the live wire. It can be understood that the connection here includes but is not limited to a direct connection method in which the first conductive area 111 and the second conductive area 112 are used as the contact parts of the socket portion 11 and the power rail 2, or an indirect connection method in which a wire is provided inside the socket portion 11 to connect with the power rail. Since the connection structure and connection method between the socket portion 111 and the track 21 of the power rail 2 belong to the common and general electrical technology category in the field, they are not necessary technical features required for the implementation of this application. Therefore, this application does not use them as limiting conditions for implementing the solution of this application, and only uses exemplary descriptions to facilitate understanding. For example, in one embodiment, if Figure 2 As shown, Figure 2 This is a schematic diagram of an application structure of a rotary joint group in an exemplary embodiment of the present application. A first roller seat 1101 in contact with the track 21 of the power rail 2 is provided at the upper end of the socket portion 11. A roller groove is provided on the first roller seat 1101, and a first roller 11011 is installed in the roller groove. The first roller 11011 can be connected to the first conductive area 111 and the second conductive area 112 through, but not limited to, a wire provided inside the socket portion 11, so that the first conductive area 111 and the second conductive area 112 are energized. In some other embodiments, different connection structures and connection methods between the socket portion 11 and the power rail 2 are selected according to the different structures and arrangements of the power rail 2 and the track 21 of the power rail 2, as well as different actual needs.

[0052] It is worth noting that the specific structural forms of the first conductive area 111 and the second conductive area 112 include but are not limited to planar areas, raised structures or recessed structures, and their connection relationship with the socket part 11 includes but is not limited to being embedded as a separate part, integrally formed as a partial structure, etc.

[0053] The plug portion 12 is provided with a first pin 121 and a second pin 122. When the plug portion 12 is plugged into the socket portion 11, it can rotate around the first axis L1 and can switch between two plugging states during the rotation process:

[0054] In the first plugging state, the first pin 121 contacts the first conductive area 111, and the second pin 122 contacts the second conductive area 112. At this time, the first pin 121 is connected to the neutral line, and the second pin 122 is connected to the live line, and a voltage difference is generated between the first pin 111 and the second pin 122.

[0055] In the second plugging state, the first pin 121 contacts the second conductive area 112 , and the second pin 122 contacts the first conductive area 111 . At this time, the first pin 121 is connected to the live wire, and the second pin 122 is connected to the neutral wire, and a voltage difference is generated between the first pin 111 and the second pin 122 .

[0056] The first axis L1 here refers to the rotation axis that the plug portion 12 rotates relative to the socket portion 11 to switch between the two plugging states after the plug portion 12 is plugged into the socket portion 11. In one embodiment, Figure 2 As shown, Figure 2 This is a schematic diagram illustrating the installation of a power rail connector in an exemplary embodiment of the present application. The plug portion 12 has a cylindrical outer structure, for example. The socket portion 11 and the plug portion 12 are also circular in shape when plugged together. The first axis is the central axis. After plugging together, the plug portion 12 rotates relative to the socket portion 12 about the central axis, i.e., the first axis L1. In other embodiments, the outer structures of the socket portion 11 and the plug portion 12 can be adjusted according to actual needs, and the first axis L1 can be determined accordingly.

[0057] It should be understood that in the above solution, the “first” and “second” in the first conductive area 111, the second conductive area 112, the first pin 121 and the second pin 122 are only used for the purpose of easy understanding and distinction, and are not used to limit the quantity. In one embodiment, Figure 2-Figure 4 As shown, there are four structures, namely, a first conductive region 111, a second conductive region 112, a first pin 121, and a second pin 122, each of which is provided with one. Every time the plug portion 12 rotates 180 degrees, the plug state switches. In other embodiments, the number of the first conductive region 111, the second conductive region 112, the first pin 121, and the second pin 122 can be adjusted according to actual needs. For example, in other embodiments, there are four structures, namely, the first conductive region 111, the second conductive region 112, the first pin 121, and the second pin 122, each of which is centrally symmetrically provided with two. Every time the plug portion 12 rotates 90 degrees, the plug state switches. Since the number of the first conductive region 111, the second conductive region 112, the first pin 121, and the second pin 122 is not a necessary technical feature for implementing the present invention, they will not be listed again. Any structural changes made to the present invention based on the above spirit should fall within the scope of implementation of the present invention.

[0058] In some embodiments, a mobile connection component is also provided on the socket portion 11, and the socket portion 11 is connected to the power rail 2 through the mobile connection component so as to move along the power rail 2. The mobile connection component may include but is not limited to a roller, a slider, etc. Correspondingly, the method of moving along the power rail 2 may include but is not limited to rolling, sliding, etc.

[0059] In one embodiment, the mobile connection assembly includes a roller that cooperates with the electric rail, specifically as follows Figure 2 As shown, Figure 2This is a schematic diagram of the installation of an electric rail connector in an exemplary embodiment of the present application. The mobile connection component is configured as a second roller 1102 arranged on both sides of the socket part 11. The second roller 1102 is overlapped on the electric rail 2. The socket part 11 can be moved along the electric rail 2 by rolling the second roller 1102.

[0060] In some embodiments, as Figure 2-Figure 4 As shown, the socket portion 11 is further provided with a grounding area 113 for connecting to a ground wire, and the plug portion 12 is provided with a third pin 123 for contacting the grounding area 113. The grounding area 113 and the third pin 123 are located on the first axis L1. When the plug portion 12 rotates about the first axis L1, the third pin 123 maintains contact with the grounding area 113. This structure is conducive to improving the safety of the rotary joint assembly and avoiding safety accidents caused by unexpected situations such as circuit instability and leakage.

[0061] In some embodiments, a spacer 114 is provided between the first conductive area 111 and the second conductive area 112. When the plug portion 12 rotates around its own axis to switch the plugging state, the spacer 114 limits the first pin 121 and the second pin 122 to prevent the plug portion 12 from being affected by environmental factors such as vibration, and repeatedly switching the plugging state when there is no need to switch the plugging state, resulting in unstable power-on state of the first pin 121 and the second pin 122.

[0062] In some embodiments, the first pin 121 and the second pin 122 are connected to the plug portion 12 via an elastic element. In normal operation, the first pin 121 and the second pin 122 maintain contact with the conductive area under the action of the elastic element. When the plug-in state is switched, the elastic element is compressed so that the first pin 121 and the second pin 122 pass through the spacing area 114.

[0063] In one embodiment, the present application specifically provides a structural solution of a rotary joint group, such as Figure 2-Figure 4As shown, the first conductive area 111 and the second conductive area 112 are both grooves, and a spacer area 114 is formed at the intersection of the grooves. The first pin 121 and the second pin 122 are conductive spheres that match the grooves of the first conductive area 111 and the second conductive area 112, and are connected to the plug part 12 through a spring 1211. When the socket part 11 and the plug part 12 are normally plugged in and powered on, the first pin 121 and the second pin 122 are pressed tightly between the first conductive area 111 and the first conductive area 112 under the elastic action of the spring 1211. In the groove of the second conductive area 112, when the plug-in state is switched, the spherical surfaces of the first pin 121 and the second pin 122 are squeezed by the spacer 114, so that the spring 1211 is compressed and the first pin 121 and the second pin 122 are moved away from the groove in the current state and cross the spacer 114. After crossing the spacer 114, the first pin 121 and the second pin 122 are no longer squeezed, and the spring 1211 is reset, pressing the first pin 121 and the second pin 122 into the groove again.

[0064] It is worth noting that in the above embodiment, after the first pin 121 and the second pin 122 of the plug portion 12 are energized, they can be connected to the electronic device to be detected by means including but not limited to external wires. Since the connection method between the plug portion 12 and the electronic device belongs to the common and general electrical technology category in the field, it is not a necessary technical feature required for the implementation of this application. Therefore, this application does not use it as a limiting condition for implementing the solution of this application. It is only explained through exemplary descriptions for ease of understanding. For example, in one embodiment, if Figure 1 、 Figure 2 or Figure 4 As shown, the plug part 12 is provided with a harness hole 1201 at the position corresponding to the first pin 121, the second pin 122 and the third pin 123. The harness hole 1201 is a through hole. The external wires pass through the harness hole 1201 and are connected to the first pin 121, the second pin 122 and the third pin 123 respectively, and are led to the outside of the plug part 12, thereby connecting to the electronic device. In other actual methods, the connection method between the plug part 12 and the electronic device can be adjusted according to actual needs. In order to avoid redundancy, they will not be listed again. Any structural changes made to the present application scheme based on the above-mentioned spiritual core should fall within the scope of implementation of the present application scheme.

[0065] In some embodiments, a transition surface is provided between the groove and the spacer 114 for guiding the first pin 121 and the second pin 122 when they pass through the spacer 114. This structure is conducive to improving the smoothness of the switching of the plug state, avoiding jamming, and reducing wear. Specifically, in one embodiment, as shown in FIG. Figure 5As shown, the transition surface can be, for example, provided with rounded corners 1111 at the edges of the grooves of the first conductive area 111 and the second conductive area 112. Due to the presence of the rounded corners 1111, when the first pin 121 and the second pin 131 contact the spacer area 114, they will be guided by the arc surface formed by the rounded corners 1111 and smoothly pass through the spacer area 114. In other embodiments, the structure of the transition surface can be adjusted according to actual needs.

[0066] In one embodiment, the first pin 121 and the second pin 122 are disposed on the end surface of the plug portion 12, and the conductive area is disposed opposite the first pin 121 and the second pin 122 on the plug portion 12. During insertion, the first pin 121 and the second pin 122 are inserted toward the socket portion 12, making insertion convenient, less prone to wear, and providing a good seal after insertion. In other embodiments, the positions of the first pin 121 and the second pin 122 on the plug portion 12 and the conductive area on the socket portion 11 can be adjusted according to actual structural requirements. For example, in some embodiments, the first pin 121 and the second pin 122 are circumferentially disposed on the outer sidewall of the plug portion 12, and the conductive area is circumferentially disposed on the inner sidewall of the socket portion 11. When the plug portion 12 and the socket portion 11 are inserted, the outer sidewall of the plug portion 12 abuts against the inner sidewall of the socket portion 11, so that the first pin 121 and the second pin 122 contact the conductive area.

[0067] In some embodiments, a limited locking structure is further provided on the rotary joint assembly to limit and guide the plug portion 12, restrict the movement of the plug portion 12 in the direction of the first axis L1, and prevent the plug portion 12 from escaping from the socket portion 11.

[0068] In one embodiment, the present application specifically provides a solution for a position-limiting locking structure, such as Figure 2-Figure 4 As shown, the limit groove 124 is arranged on the outer wall of the plug part 12, specifically at the position where the outer wall of the plug part 12 is connected to the inner wall of the socket part 11, and forms an annular groove around the outer wall of the plug part 12. The limit member is configured as a limit screw 11031. The number of limit screws 11031 can be, for example, three. When the plug part 12 is not plugged in, the limit screw 11031 can be freely screwed in or out of the threaded hole 1103. After the plug part 12 is plugged into the socket part 11, the limit screw 11031 is screwed in through the threaded hole 1103 opened on the socket part 11 and inserted into the limit groove 124, so that the rotation of the plug part 12 is always maintained on the plane where the three limit screws 11031 are located, thereby realizing guidance. At the same time, the engagement relationship between the limit screw 11031 and the limit groove 124 also prevents the plug part 12 from loosening and falling off from the socket part 11 during rotation.

[0069] It can be seen that in a rotary joint group of the above scheme, by arranging the first conductive area 111 and the second conductive area 112 on the socket part 11, the plug part 12 has two plug-in states that can be switched with each other when it rotates relative to the socket part 11. The plug part 12 rotates relative to the socket part 11 to realize the switching of the two plug-in states. It can adjust its own plug-in state while keeping the power on, effectively avoid problems such as wire tangling and plug falling off, reduce the need for manual maintenance, and greatly improve the convenience and reliability of connection.

[0070] In one embodiment, the present application provides a detection line using an electric rail connector 1, including an electric rail 2 and a conveyor line 3 for conveying a carrier 301. The electric rail 2 is annular. It should be understood that the annular shape here can be a regular or irregular annular shape including but not limited to a rectangular ring, an elliptical ring, etc. The specific shape structure may vary depending on the actual situation. The purpose of this description is not to limit the specific shape of the electric rail 2, but to limit the function it performs. At least one set of electric rail connectors 1 is provided on the electric rail 2, and the optional connector group 1 can circulate on the annular electric rail 2. The present application specifically provides a solution for a detection line using an electric rail connector 1, such as Figure 6 As shown, the power rail 2 is formed into a ring by straight sections at the upper and lower ends and arc sections at the left and right ends. The conveyor line 3 is close to the straight section at the upper end of the power rail 2 and is arranged horizontally. In this embodiment, the electronic device to be tested can be, for example, a computer 302. The computer 302 is placed on the carrier 301. The carrier 301 on the conveyor line 3 is connected to the plug part 12 of the power rail connector 1 through a wire and powered on, thereby enabling the computer 302 to be powered on by connecting to the electrical interface on the carrier. During the conveying process, the carrier 301 pulls the power rail connector 1 to move on the power rail 2 through the wire to keep the carrier 301 and the computer 302 powered on.

[0071] In some embodiments, an electronic device testing line further includes a reflow line 4 for reflowing the carrier 301. The reflow line 4 is used to reflow the carrier 301. The reflow here refers to transporting the carrier 301 in the opposite direction relative to the conveying line 3. In this embodiment, Figure 6As shown, the return line 4 is close to the straight section at the lower end of the rail 2 and is arranged horizontally. When the carrier 301 is transported to the left end of the conveyor line 3 by the conveyor line 3, the carrier 301 is removed and placed in the left end of the return line 4 for return flow. During this process, the rail connector 1 and the carrier 301 are kept connected by a wire. During the return flow process, the carrier 301 pulls the rail connector 1 to move on the rail 2 through the wire until the carrier 301 returns to the right end of the return line 4. The carrier 301 is removed and placed in the right end of the conveyor line 3. During this process, the rail connector 1 and the carrier 301 are kept connected by a wire. In the above manner, the rail connector 1 always circulates on the rail 2 without being removed, and since the plug group 12 of the rail connector 1 is rotatable, during the circulation process, the wire used to connect the rail connector 1 and the carrier 301 can adjust its own torsion by the rotation of the plug group 12, and there will be no wire knotting.

[0072] In some embodiments, the return line 4 can be used only to recover the carrier 301, and the power rail 2 near the return line 4 is not energized, which facilitates the inspection and maintenance of the carrier 301 on the return line 4. In other embodiments, the return line 4 can be used for the detection of electronic equipment at the same time as the conveyor line 3, so as to realize the detection of electronic equipment from two directions using the same power rail 2. The above scheme can be adjusted according to the structure of the power rail 2 and actual needs, and no additional limitation is made here.

[0073] In some embodiments, an electronic equipment detection line further includes a lifting device 5 provided at both ends of the conveyor line 3 and the return line 4. The return line 4 and the conveyor line 3 form a circulation path through the lifting device 5, so that the carrier 301 circulates along with the electric rail connector 1 in the circulation path. It can be understood that the lifting device 5 is a device with a lifting function and can transport the carrier 301 between the conveyor line 3 and the return line 4. Its specific structure can be an elevator, a bracket driven by a cylinder or an electric cylinder, etc. The process of the carrier 301 entering or leaving the lifting device 5 can be achieved by including but not limited to manual operation, or setting a motor-driven transfer belt or roller at the position where the lifting device 5 contacts the carrier 301. Its implementation method belongs to the application scope of electrical control technology, rather than as a necessary technical feature to realize the present application, so it is only briefly listed without specific limitation. In this embodiment, if Figure 6As shown, the left and right ends of the conveyor line 3 and the return line 4 are provided with a lifting device 5, and the lifting device 5 is, for example, an elevator. The carrier 301 drags the rail connector 1 to the left end of the conveyor line 3. After the computer 302 completes the inspection, it is removed from the carrier 301, and the carrier 301 enters the lifting device 5 on the left. The lifting device 5 drives the carrier 301 and moves downward, and then sends it into the return line 4 from the left end. During this process, the carrier 301 and the rail connector 1 are always connected by a wire; after entering the return line 4, the carrier 301 drags the rail connector 1 to the right end of the return line through the wire, enters the lifting device 5 on the right, and the lifting device 5 drives the carrier 301 upward After moving, it is sent into the conveyor line 3 from the right end. During this process, the carrier 301 and the rail connector 1 are still always connected by a wire. After entering the conveyor line 3, the carrier 301 continues to drag the rail connector 1 to the left through the wire. At this time, the computer 302 can be placed on the carrier for power-on detection. In the above embodiment, the carrier 301 drags the rail connector 1 through the wire and circulates continuously. During this period, since the carrier 301 only moves horizontally, the rail connector 1 rotates with the rail 2. Therefore, in each cycle, the plug part 12 of the rail connector 1 will rotate 360 degrees, that is, the plug-in state will be switched twice. This process effectively avoids problems such as wire tangling.

[0074] It can be seen that in an electronic equipment detection line of the above scheme, a ring-shaped power rail is set and a rotary joint group is set on the power rail, so that the rotary joint group can circulate on the power rail, and the rotary joint group can be kept powered on without the need to re-take it out or re-plug it. This effectively improves the shortcoming of the existing technology that the joint needs to be manually taken out and placed from the power rail, greatly improves the detection efficiency of electronic equipment on the detection line, and reduces the labor cost of electronic equipment detection.

[0075] In one embodiment, the present application provides a detection method applicable to an electronic device detection line, which is applicable to an electronic device detection line in the above embodiment, including:

[0076] Place the carrier 301 at the entrance of the conveyor line 3, and drag the rail connector 1 on the rail 2 to move along the conveyor line 3;

[0077] When the carrier 301 moves on the conveyor line 3 , electronic devices are loaded and unloaded on the carrier 301 for testing;

[0078] When the carrier 301 moves to the outlet end of the conveyor line 3, it enters the inlet end of the return line 4 through the lifting device 5. During this process, the moving direction of the carrier 301 changes by 180 degrees, and the electric rail connector 1 completes the switching of the plug-in state once;

[0079] When the carrier 301 moves to the outlet end of the return line 4, it enters the inlet end of the conveyor line 3 through the lifting device 5. During this process, the moving direction of the carrier 301 changes 180°, and the electric rail connector 1 completes the switching of the plug-in state.

[0080] Specifically, in this embodiment, Figure 6 As shown, the left and right ends of the conveyor line 3 and the return line 4 are provided with a lifting device 5, and the lifting device 5 is, for example, an elevator. The carrier 301 drags the rail connector 1 to the left end of the conveyor line 3. After the computer 302 completes the inspection, it is removed from the carrier 301, and the carrier 301 enters the lifting device 5 on the left. The lifting device 5 drives the carrier 301 and moves downward, and then sends it into the return line 4 from the left end. During this process, the carrier 301 and the rail connector 1 are always connected by a wire. The moving direction of the carrier 301 changes 180° from rightward movement to leftward movement, and the rail connector 1 completes the switching of the plug-in state once; after entering the return line 4, the carrier 301 drags the rail connector 1 to the return line 4 through the wire. At the right end of the streamline, it enters the lifting device 5 on the right. After the lifting device 5 drives the carrier 301 to move upward, it is sent to the conveyor line 3 from the right end. During this process, the carrier 301 and the rail connector 1 are still always connected through the wire. The moving direction of the carrier 301 changes 180° from moving to the left to moving to the right, and the rail connector 1 completes the switching of the plug-in state once; after entering the conveyor line 3, the carrier 301 continues to drag the rail connector 1 to the left through the wire. At this time, the computer 302 can be placed on the carrier for power-on detection. In the above embodiment, the carrier 301 drags the rail connector 1 through the wire, and the cycle continues. During this period, since the carrier 301 only moves horizontally, the rail connector 1 rotates with the rail 2.

[0081] In a detection method applicable to an electronic equipment detection line of the above scheme, a ring-shaped power rail is set and a rotary joint group is set on the power rail, so that the rotary joint group can move in a circular motion on the power rail. The rotary joint group can be kept in a powered state without the need to re-take it out or re-plug it. This effectively improves the shortcoming of the existing technology that the joint needs to be manually taken out and placed from the power rail, greatly improves the detection efficiency of electronic equipment on the detection line, and reduces the labor cost of electronic equipment detection.
