DETAILED DESCRIPTION

[0024] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0027] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0028] One of the preferred embodiments of the present application is as follows: Figures 1 to 7 As shown, a power-on detection device for the production of electric meters includes a frame 100, a conveying mechanism 2, a transposition mechanism 3, a plurality of adjustment components 4, and a plurality of pairs of detection components 5. A detection station is provided on the frame 100. The electric meter 600 that has been produced needs to be powered on to ensure that its quality meets the requirements. The electric meter 600 to be tested can be placed in the detection station for testing. The conveying mechanism 2 is installed on the frame 100. When testing the electric meter, the electric meter to be tested can be placed at the front end of the conveying mechanism 2. Then, the conveying mechanism 2 can fix the electric meter 600 to be tested and transport it to the detection station to ensure that the electric meter 600 can be stably powered on. The transposition mechanism 3 is installed at the detection station, and a plurality of adjustment components 4 are installed on the transposition mechanism 3 along the circumferential direction. Each adjustment component 4 is installed with a pair of detection components 5 for powering on the electric meter 600. The structural type of the detection component 5 installed on each adjustment component 4 is different. According to the type of the power meter 600 transported to the detection station, the switching mechanism 3 can drive the corresponding type of detection component 5 to the detection end facing downward by driving the adjustment component 4 to enter the working state. Then, the adjustment component 4 adjusts the position of the detection component 5 in the working state according to the model of the power meter 600, so that the detection component 5 moves downward under the drive of the switching mechanism 3, and can then be aligned and inserted into the connection hole 610 to be detected on the power meter 600 to complete the power-on detection process.

[0029] It should be known that there are many types of power meters 600, and common power meters 600 include ammeters, voltmeters, and multimeters. Due to the different types of power meters 600, the structures of the corresponding connection holes 610 may be different, and thus the structures of the detection components 5 required for different types of power meters 600 may not be the same. At the same time, for the same type of power meters 600, the structural dimensions of the connection holes 610 corresponding to different models may also be different, and thus the structures of the detection components 5 required for power meters 600 of the same type and different models may also be different. In order to realize the detection of different types of power meters 600 and different models of power meters 600 of the same type, this embodiment requires a plurality of different types of detection components 5, and correspondingly, there are adjustment components 4 corresponding to the number of types of detection components 5 to realize the position adjustment of different types of detection components 5.

[0030] It is understandable that the specific number of detection components 5 can be set according to the detection requirements to be implemented, for example Figure 1As shown, there are three types of detection components 5, and there are also three corresponding adjustment components 4. In order to avoid interference between different detection components 5, the three adjustment components 4 can be arranged circumferentially, and then the detection components 5 of the three structural types installed on the adjustment components 4 are also arranged circumferentially accordingly. Specifically, the direction of the rotation axis of the circumferential arrangement of the adjustment components 4 is perpendicular to the moving direction of the power meter 600, and then the transposition mechanism 3 can drive any adjustment component 4 to carry the corresponding detection component 5 downward, so as to facilitate the power-on detection of the corresponding power meter 600. In order to facilitate the description of the subsequent content, the subsequent content will be described by taking the detection component 5 having three structural types as an example.

[0031] It can also be understood that when performing power-on detection of the power meter 600, the live wire and the neutral wire are generally connected, so two detection components 5 are installed on each adjustment component 4 to connect the live wire and the neutral wire respectively.

[0032] For ease of understanding, the specific working process of this application can be briefly described below.

[0033] First, the power meter 600 to be tested is placed at the front end of the conveying mechanism 2. At this time, the type and model of the power meter 600 can be detected by the detection head installed at the front end of the rack 100, or when producing batches of power meters 600 of corresponding types and models, the type and model of the power meter 600 can be determined by manual input.

[0034] Then, the transposition mechanism 3 moves the whole composed of three adjustment components 4 upward according to the detected data or input data to avoid interference between the subsequent adjustment components 4 and the conveying mechanism 2 during the rotation process. After the transposition mechanism 3 lifts the adjustment components 4, according to the type and model of the power meter 600 to be detected, the transposition mechanism 3 can drive the three adjustment components 4 to rotate in a circle until the adjustment component 4 equipped with the detection component 5 corresponding to the power meter 600 to be detected is rotated to the bottom, so that the detection end of the detection component 5 installed on the adjustment component 4 is vertically downward.

[0035] At the same time, when the switching mechanism 3 drives the adjustment component 4 to rotate, the adjustment component 4 itself can also adjust the position of the detection component 5 installed thereon according to the type and model of the power meter 600 to be detected, thereby ensuring that when the detection end of the detection component 5 is facing downward, the positions of the two detection components 5 can exactly correspond to the position of the connection hole 610 on the power meter 600 to be detected located at the detection station.

[0036] Finally, the shifting mechanism 3 can drive the adjustment component 4 downward as a whole, and then the detection component 5 with the detection end facing downward can be moved downward under the drive of the shifting mechanism 3 until the detection end of the detection component 5 is inserted into the connection hole 610 of the power meter 600 to be tested, and then power is turned on and the response status of the power meter 600 is observed to determine whether the power meter 600 is qualified.

[0037] In this embodiment, there are various structures of the transposition mechanism 3 that can realize the above functions, one of which is as follows: Figure 1 and Figure 3 As shown, the transposition mechanism 3 includes a support seat 31, a first telescopic device 33, a second rotating device 32 and a rotating shaft 34. The number of the support seats 31 is a pair, and they are symmetrically arranged on both sides of the frame 100 along the conveying direction of the conveying mechanism 2. The support seats 31 are vertically slidably installed on the frame 100 through the support frame 311 vertically arranged at the bottom. Both support seats 31 are provided with a rotating seat, and the rotating shaft 34 can be rotatably installed on the rotating seat on the support seat 31 through both ends. The number of the first telescopic device 33 is a pair and they are vertically fixedly installed on both sides of the frame 100 respectively. The output end of the first telescopic device 33 is connected to the support seat 31, and then the support seat 31 can carry the rotating shaft 34 to move vertically under the drive of the first telescopic device 33; specifically, multiple adjustment components 4 are fixedly installed on the rotating shaft 34 along the circumferential direction, and the vertical movement of the rotating shaft 34 will carry all the adjustment components 4 to run synchronously. The second rotating device 32 is fixedly mounted on one of the support seats 31 and connected to the rotating shaft 34 through the output end. The rotating shaft 34 can rotate in a circle under the drive of the second rotating device 32, so that any adjustment component 4 can be driven to have the detection end of the detection component 5 thereon facing downward.

[0038] Specifically, when the structural type of the detection component 5 needs to be changed, the first telescopic device 33 will drive the shaft 34 carrying the adjustment component 4 and the detection component 5 to move up to the set height to ensure that the detection component 5 will not interfere with the conveying mechanism 2, and then the second rotating device 32 will drive the shaft 34 to rotate until the detection end of the required detection component 5 is facing downward and the rotation of the shaft 34 is stopped. Subsequently, when the power meter 600 to be tested is located at the testing station, the first telescopic device 33 will drive the support seat 31 to move downward as a whole until the corresponding detection component 5 is inserted into the connection hole 610 of the power meter 600.

[0039] It should be noted that the specific structure and working principle of the first telescopic device 33 and the second rotating device 32 are well known to those skilled in the art, so they will not be elaborated in detail here. Common first telescopic devices 33 include air cylinders, hydraulic cylinders, and linear motors, etc.; common second rotating devices 32 include motors, rotary air cylinders, and rotary hydraulic cylinders, etc.

[0040] In this embodiment, there are many specific structures of the conveying mechanism 2 that can realize the above-mentioned conveying function, one of which is as follows: Figure 1 As shown, the conveying mechanism 2 includes a conveyor belt 21 and a first rotating device 22; the conveyor belt 21 is installed on rollers installed at both ends of the frame 100, and the first rotating device 22 is installed on the frame 100 and is drivingly connected to one of the rollers. A plurality of continuous placement cavities 210 are provided on the conveyor belt 21, and the electric power meter 600 to be tested is suitable for being placed in the placement cavity 210, and then moved to the testing station under the transportation of the conveyor belt 21. Specifically, a clamp is installed on each placement cavity 210 of the conveyor belt 21, and the specific structure of the clamp is the prior art, so it will not be elaborated in detail here; when the electric power meter 600 to be tested is placed in the placement cavity 210, the clamp can clamp and position the electric power meter 600 to ensure the stability of the electric power meter 600 during the conveying process.

[0041] It should be known that the specific structure and working principle of the first rotating device 22 are well-known technologies to those skilled in the art, so they will not be elaborated in detail here. Common first rotating devices 22 include motors, rotating cylinders, rotating hydraulic cylinders, etc.

[0042] It should also be known that, since the conveyor belt 21 is made of rubber, when carrying the power meter 600 to the inspection station for inspection, the conveyor belt 21 may be bent concavely due to the influence of gravity, thereby causing the power meter 600 to tilt, which may cause the subsequent inspection component 5 to be unable to be aligned and inserted into the connection hole 610 of the power meter 600. Therefore, when inspecting the power meter 600, the rotating shaft 34 and the conveyor belt 21 are matched through the positioning structure, so that when the rotating shaft 34 moves downward to inspect the power meter 600, the rotating shaft 34 can lock and tighten the conveyor belt 21 through the positioning structure.

[0043] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, the positioning structure includes positioning holes 211 disposed on the conveyor belt 21 and located on both sides of the placement cavity 210, and multiple pairs of positioning rods 341 disposed along the circumferential direction on the rotating shaft 34. Among them, the number of positioning holes 211 on each side of the placement cavity 210 is at least one, so when the power meter 600 is tested, at least one pair of positioning rods 341 facing downward can move downward with the rotating shaft 34 until they are plugged into the corresponding positioning holes 211.

[0044] It should be known that the specific number of the positioning holes 211 on one side of the placement cavity 210 can be determined according to actual needs, for example Figure 1As shown, a positioning hole 211 is provided on both sides of the placement cavity 210, and the positioning hole 211 corresponds to the midpoint of the length of the placement cavity 210. Accordingly, three pairs of positioning rods 341 are fixedly installed on the rotating shaft 34, and the two positioning rods 341 of each pair are respectively provided on both sides of the corresponding adjustment component 4 along the axial direction of the rotating shaft 34.

[0045] In order to facilitate the understanding of the following content, the position change of the connection hole 610 of the same type of different models of power meters 600 can be described. Figure 2 As shown, assuming that the power meter 600 is placed in the placement cavity 210, the power meter 600 always abuts against a corner of the placement cavity 210, for example Figure 2 The lower left corner of the figure. As the size of the power meter 600 decreases, that is, the size of the power meter 600 decreases; the distance from the leftmost connection hole 610 of the large power meter 600 to the left side of the placement cavity 210 is reduced from X1 to the distance X2 from the leftmost connection hole 610 of the small power meter 600 to the left side of the placement cavity 210. The distance from the connection hole 610 of the large power meter 600 to the lower side of the placement cavity 210 is reduced from Y1 to the distance Y2 from the connection hole 610 of the small power meter 600 to the lower side of the placement cavity 210. The distance Z1 between adjacent connection holes 610 of the large power meter 600 is reduced to the distance Z2 between adjacent connection holes 610 of the small power meter 600. Assuming that the directions corresponding to dimensions Y1 and Y2 are front-to-back directions, and the directions corresponding to dimensions X1 and X2 are left-to-right directions; when testing different types of power meters 600, the adjustment component 4 needs to adjust the front-to-back distance, left-to-right distance and the spacing between the two detection components 5 installed thereon.

[0046] To achieve the above functions, one of the embodiments of the present application is as follows: Figures 5 to 7 As shown, the adjustment assembly 4 includes a connecting seat 41, a sliding seat 42, a mounting seat 43, a second telescopic device 44 and a displacement assembly 45. The connecting seat 41 is fixedly mounted on the rotating shaft 34, the sliding seat 42 is slidably mounted on the connecting seat 41, the second telescopic device 44 is mounted on the connecting seat 41 and connected to the sliding seat 42 through the output end, the mounting seat 43 is slidably mounted on the sliding seat 42 and cooperates with the connecting seat 41 through the guide structure, and the moving direction of the mounting seat 43 along the sliding seat 42 is perpendicular to the moving direction of the sliding seat 42 along the connecting seat 41. The displacement assembly 45 is mounted on the mounting seat 43 and is drivingly connected to the detection assembly 5, and the displacement assembly 45 is used to adjust the distance between the two detection assemblies 5; the second telescopic device 44 is suitable for driving the sliding seat 42 to drive the detection assembly 5 to adjust the front and rear positions, and in the process of the sliding seat 42 moving, the mounting seat 43 is suitable for adjusting the left and right positions of the detection assembly 5 through the guide structure.

[0047] It should be known that, when the model of the power meter 600 to be detected is determined, the corresponding dimensional data Y1, Y2 to Yn, and X1, X2 to Xn are determined and corresponding, that is, the dimensional data Y1 and X1 are corresponding, the dimensional data Y2 and X2 are corresponding, and the dimensional data Yn and Xn are corresponding; therefore, when the second telescopic device 44 drives the sliding seat 42 to drive the detection component 5 to adjust the front and rear positions, according to the corresponding data, the guide structure can be used to drive the mounting seat 43 to adapt to the left and right directions, thereby reducing the complexity of the structural design of the adjustment component 4. Among them, n represents the number of models of the power meter 600.

[0048] It should also be known that the specific structure and working principle of the second telescopic device 44 are well known to those skilled in the art, so they will not be elaborated in detail here. Common second telescopic devices 44 include air cylinders, hydraulic cylinders, and linear motors.

[0049] Specifically, Figure 5 and Figure 6 As shown, the sliding seat 42 is slidably connected to the connecting seat 41 in the front-to-back direction through at least one sliding rod 421, and preferably, the number of the sliding rods 421 is two and symmetrically arranged on both sides of the sliding seat 42. The number of the second telescopic device 44 is at least one, preferably two, and they are respectively matched and connected with both sides of the sliding seat 42.

[0050] In this embodiment, Figure 5 and Figure 6 As shown, the mounting seat 43 is slidably mounted on the sliding seat 42 in the left-right direction, and the first end of the mounting seat 43 is connected to the sliding seat 42 through the first spring 46, so that the mounting seat 43 and the sliding seat 42 are elastically slidably mounted in the left-right direction. The connecting seat 41 is provided with an extension portion close to the second end of the mounting seat 43, and a matching edge 411 is provided on one side of the extension portion close to the second end of the mounting seat 43. The thickness of the extension portion along the left-right direction is uneven, so that the position of the formed matching edge 411 is variable, and then the mounting seat 43 can elastically abut against the matching edge 411 through the second end to form a guide structure. Therefore, in the process of the sliding seat 42 moving, the mounting seat 43 slides forward and backward with the sliding seat 42, and at the same time, under the elastic force of the first spring 46, the mounting seat 43 always abuts against the matching edge 411 at different positions through the second end, so as to adjust the left-right position of the mounting seat 43.

[0051] Specifically, there are many ways to set the matching edge 411. In one specific example, the matching edge 411 is a continuous edge, that is, the matching edge 411 is a continuous inclined straight edge or an arc edge. Then, when the mounting seat 43 moves forward and backward with the sliding seat 42, the mounting seat 43 can achieve corresponding left and right movement by abutting against different positions of the matching edge 411 through the second end under the action of elastic force. In another specific example, Figure 6 As shown, there are multiple mating edges 411, and the multiple mating edges 411 are arranged at intervals along the front-to-back direction of the extension portion, and the distances of the multiple mating edges 411 to the sliding seat 42 along the sliding direction of the mounting seat 43 are different, and adjacent mating edges 411 are connected by inclined connecting edges 412. In the process of the sliding seat 42 moving forward and backward, the mounting seat 43 slides along the sliding seat 42 under the action of elastic force and abuts against different mating edges 411, thereby realizing the left and right movement of the mounting seat 43. For the convenience of description, the subsequent content is explained by taking multiple mating edges 411 as an example.

[0052] It is understandable that the specific number of the matching edges 411 can be determined according to the number of models of the power meter 600, for example Figure 6 As shown, assuming that there are three types of electric power meters 600 , the number of the matching edges 411 is three.

[0053] In this embodiment, Figure 5 and Figure 6 As shown, the displacement assembly 45 includes a third rotating device 451, a bidirectional screw 452 and a pair of sliders 453. The bidirectional screw 452 is rotatably mounted on the mounting seat 43 and its extension direction is parallel to the sliding direction of the mounting seat 43; the sliders 453 are respectively matched with the two sides of the bidirectional screw 452, and the detection assembly 5 is correspondingly mounted on the sliders 453; the third rotating device 451 is mounted on the mounting seat 43 and connected to the bidirectional screw 452 through the output end, and then the bidirectional screw 452 drives the slider 453 to carry the detection assembly 5 to move toward or away from each other under the drive of the third rotating device 451 to adjust the distance between the two detection assemblies 5.

[0054] It should be known that the specific structure and working principle of the third rotating device 451 are well-known technologies to those skilled in the art, so they will not be elaborated in detail here. Common third rotating devices 451 include motors, rotating cylinders, rotating hydraulic cylinders, etc.

[0055] In this embodiment, Figure 7As shown, the detection assembly 5 includes a power connection pin 51 and a protective sleeve 53; the power connection pin 51 is elastically slidably mounted on the slider 453 through the second spring 52, and the protective sleeve 53 is elastically slidably mounted on the slider 453 through the third spring 54 and sleeved on the outer side of the power connection pin 51. Then, when the power connection pin 51 is aligned and inserted into the connection hole 610 on the power meter 600, the protective sleeve 53 can seal the insertion area of ​​the power connection pin 51 and the connection hole 610.
