[0022] The tray assembly is used to carry the electric energy meter and perform assembly line testing. The existing tray assembly includes a base and a limit portion. The limit portion is arranged on the base to limit and fix the electric energy meter carried on the base, thereby ensuring the stability of the fixation of the electric energy meter. The electric energy meter includes various types such as single-phase meters, three-phase meters and terminal meters. In the related art, by simultaneously setting a variety of limit portions on the tray assembly to adapt to different types of electric meters, it is necessary to set a variety of pressing structures according to the variety of limit portions. At this time, integrating a variety of pressing structures into the same component will cause the problem of occupying a large space and complex design.

[0023] In view of this, see Figure 1-Figure 13 In an embodiment of the present invention, a pressing device 100 is provided in an embodiment of the present invention, which is used to control a tray assembly 20. The tray assembly 20 is used to carry an electric energy meter. The tray assembly 20 is used to carry an electric energy meter and perform assembly line detection. The tray assembly 20 may include a base 210, a first limiting portion 222, and a second limiting portion 223. The first limiting portion 222 and the second limiting portion 223 are respectively arranged on the base 210 and respectively limit and fix the two electric energy meters carried on the base 210, thereby ensuring the stability of the fixation of the electric energy meter. The electric energy meter includes various types such as single-phase electric energy meters, three-phase electric energy meters, and terminal electric energy meters. Therefore, according to the needs, it is necessary to press the first limiting portion 222 and the second limiting portion 223, and make the remaining limiting portions protrude from the base 210 to play a limiting role. The pressing device 100 of the present invention plays the role of pressing the first limiting portion 222 and the second limiting portion 223. Specifically, the pressing device 100 includes a base plate 110 , a cylinder assembly 120 and a pressing assembly 130 .

[0024] It should be noted that, in some embodiments, the structure of the limiting portion (the first limiting portion 222, the second limiting portion 223, etc.) of the tray assembly 20 described in the present invention may have overlapping parts. For example, the first limiting portion 222 includes a first block 1321 and a second block 1322 for limiting, and the second limiting portion 223 includes a second block 1322 and a third block 1323 for limiting. When the first limiting portion 222 is in a limiting state (the first block 1321 and the second block 1322 are both raised) and needs to be switched to the limiting state of the second limiting portion 223 (the second block 1322 and the third block 1323 are both raised), it is only necessary to press the first block 1321 back and press to raise the third block 1323. In other embodiments, the structures of the limiting parts of the tray assembly 20 may not overlap with each other. For example, the first limiting part 222 includes a first block 1321 and a second block 1322 for limiting, and the second limiting part 223 includes a third block 1323 and a fourth block 1311 for limiting. When the first limiting part 222 is in a limiting state (the first block 1321 and the second block 1322 are both raised) and needs to be switched to the limiting state of the second limiting part 223 (the third block 1323 and the fourth block 1311 are both raised), it is necessary to press back the first block 1321 and the second block 1322, and press to raise the third block 1323 and the fourth block 1311.

[0025] For details, see Figure 1-Figure 2 as well as Figure 6-Figure 7 , corresponding to the requirement that the tray assembly 20 needs to be pressed, the first pressing structure 131 is suitable for pressing the first limiting portion 222 of the tray assembly 20, and the second pressing structure 132 is suitable for pressing the second limiting portion 223 of the tray assembly 20. In addition, according to the requirements, in some embodiments, in addition to the first pressing portion and the second pressing portion, the bottom plate 110 of the pressing device 100 can also be connected to other pressing structures, such as a third pressing structure, which is suitable for pressing the third limiting portion of the tray assembly 20. It can be understood that the structure and arrangement of the third pressing structure can be the same or similar to those of the first pressing structure 131 and the second pressing structure 132, and the difference can only be that the target pressing structure or position is different.

[0026] See also Figure 1-Figure 2 as well as Figure 6-Figure 7In order to drive the first pressing part or the second pressing part to perform a pressing operation, the cylinder assembly 120 is connected to the bottom plate 110, and the cylinder assembly 120 includes a first cylinder 121 and a second cylinder 122. The first cylinder 121 is configured to drive the first pressing structure 131 to press the first limiter 222, and the second cylinder 122 is configured to drive the second pressing structure 132 to press the second limiter 223. The first cylinder 121 and the second cylinder 122 can be one of an electric cylinder, a pneumatic cylinder, and a hydraulic cylinder, and the type or structure of the first cylinder 121 and the second cylinder 122 can be the same or different. Through the above arrangement, the first cylinder 121 and the second cylinder 122 as the driving source, and the first pressing structure 131 and the second pressing structure 132 as the abutting driving member can be integrated and connected to the bottom plate 110. When the first pressing structure 131 and the second pressing structure 132 need to be driven to extend or retract relative to each other under different circumstances, the pressing device 100 of the present invention has high integration and simple structure. In addition, the first pressing structure 131 and the second pressing structure 132 can move in opposite directions at the same time, that is, one of them is extended while the other is retracted, so that the state switching speed is faster and the working efficiency is higher. In order to enable the pressing device 100 to align the tray assembly 20, in some embodiments, the pressing device 100 may include a driving assembly, which can drive the bottom plate 110 to move relative to the tray assembly 20. The driving device can be connected only to the bottom plate 110, so as to indirectly drive the cylinder assembly 120 and the pressing assembly 130, so that the driving method is more efficient.

[0027] In the technical solution of the present invention, the pressing device 100 includes a bottom plate 110, a cylinder assembly 120 and a pressing assembly 130. Corresponding to the requirement that the tray assembly 20 needs to be pressed, the first pressing structure 131 is suitable for pressing the first limit portion 222 of the tray assembly 20, and the second pressing structure 132 is suitable for pressing the second limit portion 223 of the tray assembly 20. The cylinder assembly 120 includes a first cylinder 121 and a second cylinder 122, the first cylinder 121 is configured to drive the first pressing structure 131 to press the first limit portion 222, and the second cylinder 122 is configured to drive the second pressing structure 132 to press the second limit portion 223. Compared with the method of making various pressing structures into separate parts and using them for pressing respectively, or the method of manual pressing in the related art, the pressing device 100 of the present invention has high integration, simple structure, faster state switching speed, and higher working efficiency. Therefore, the pressing device 100 of the present invention can make the integration higher and the efficiency of the pressing operation higher.

[0028] For ease of description, the cylinder bodies described below all refer to the first cylinder body 121 and / or the second cylinder body 122 , the pressing structures all refer to the first pressing structures 131 and / or the second pressing structures 132 , and the limiting parts all refer to the first limiting parts 222 and / or the second limiting parts 223 .

[0029] For detailed settings of the pressing structure, see Figure 1-Figure 3 In some embodiments, the first pressing structure 131 includes a plurality of first pressing blocks, and the second pressing structure 132 includes a plurality of second pressing blocks. The first pressing blocks and the second pressing blocks can be in any suitable shape and arrangement. In addition, for the first pressing blocks. The first pressing blocks can be connected as one piece, that is, the first pressing blocks connected as one piece can be parts of the one-piece structure, and the extension directions of the first pressing blocks can be different. The second pressing blocks can also be arranged in the same way. The pressing assembly 130 includes a first plate body 133 and a second plate body 134. The first cylinder body 121 is connected to one side of the first plate body 133, and the first pressing blocks are connected to the other side. The second cylinder body 122 is connected to one side of the second plate body 134, and the second pressing blocks are connected to the other side. Taking the arrangement of the first plate 133 as an example, it can be understood that the first plate 133 is used to connect the first cylinder 121 and each first pressing block, which can improve the integration of the pressing device 100, and the first cylinder 121 and each first pressing block are respectively connected to the two sides of the first plate 133, which can prevent the arrangement and movement of the first cylinder 121 from affecting the arrangement and pressing action of each first pressing block, and the arrangement effect of the second plate 134 is similar to the arrangement effect of the first plate 133. According to requirements, in other embodiments, the first pressing structure 131 can include only one first pressing block, or the second pressing structure 132 can include only one second pressing block.

[0030] When a plurality of first pressing blocks and a plurality of second pressing blocks are provided according to the above-mentioned embodiment, in order to avoid interference between the first pressing blocks and the second pressing blocks, see Figure 1-Figure 3 In some embodiments, along the driving direction of the first cylinder 121, the first plate 133 is arranged between the base plate 110 and the second plate 134, that is, the first plate 133 and the second plate 134 are stacked in sequence on the same side of the base plate 110. In order to avoid the telescopic action of the first cylinder 121 connected to the first plate 133 from being interfered with by the second pressing blocks or the second plate 134, the second pressing blocks and the second plate 134 jointly form an avoidance groove 135, and the first cylinder 121 can drive each first pressing block to at least partially extend out of the avoidance groove 135.

[0031] For details of the avoidance groove 135 set above, see Figure 1-Figure 3In some embodiments, the driving direction of the first cylinder 121 and the driving direction of the second cylinder 122 are both the first direction X, the second pressing block includes the first block 1321, the second block 1322 and the third block 1323, and the first pressing block includes the fourth block 1311, the fifth block 1312 and the sixth block 1313. Based on this, in some embodiments, along the second direction Y perpendicular to the first direction X, one side of the first block 1321 is arranged with the second block 1322 to form a first groove 1351, and the other side is provided with the third block 1323, along the third direction Z perpendicular to the first direction X and the second direction Y, the fifth block 1312 and the sixth block 1313 are respectively located on both sides of the third block 1323, and the third block 1323 is separated and defines the second groove 1352 and the third groove 1353 on both sides of the first block 1321. Through the first slot 1351, the second slot 1352 and the third slot 1353 defined above, the fourth block 1311, the fifth block 1312 and the sixth block 1313 can provide telescopic avoidance space respectively, and the first cylinder 121 can drive the fourth block 1311 to at least partially extend out of the first slot 1351, drive the fifth block 1312 to at least partially extend out of the second slot 1352, and drive the sixth block 1313 to at least partially extend out of the third slot 1353. In addition, see Figure 1-Figure 3 In some embodiments, each block in the first pressing block is symmetrically arranged along the second direction Y with the extension axis of the first groove 1351 as the symmetry axis. Similarly, each block in the second pressing block is symmetrically arranged along the second direction Y with the extension axis of the first groove 1351 as the symmetry axis. Through the above-mentioned distribution arrangement of each block, the structure of each second pressing block and the second plate 134 itself can be fully utilized to form the avoidance groove 135, and the distribution of the avoidance groove 135 is reasonable, and the space utilization rate is high, so that each first pressing block and the second pressing block can be distributed more closely, and can adapt to the complex situation where the pressing positions intersect each other under different requirements.

[0032] Based on the setting of multiple first pressing blocks, for the first cylinder body 121, in some embodiments, the number of first cylinder bodies 121 is multiple, and each first pressing block can be driven one-to-one. In other embodiments, at least one first cylinder body 121 (the first cylinder body 121 can be one or more) can drive multiple first pressing blocks at the same time. At the same time, the second cylinder body 122 can also be set in the same way.

[0033] In order to make the pressing structure have a better pressing effect on the limit part, refer to Figure 4In some embodiments, the first pressing structure 131 further includes a first detection member 1315. The first pressing structure 131 is suitable for pressing a side of the first position-limiting portion 222 and has a first detection hole 1314. The cross section of the first detection hole 1314 can be in any suitable shape. The first detection member 1315 is arranged in the first detection hole 1314 so that the first detection member 1315 can detect the position of the first position-limiting portion 222. It can be understood that after the first detection member 1315 is arranged in the first detection hole 1314, the first detection member 1315 can pass through the first detection hole 1314 toward the first position-limiting portion 222, and then can detect whether the first position-limiting portion 222 is pressed to the target position by the first pressing structure 131. The detection method can be any suitable detection method such as laser, infrared sensor, visual sensor, etc. It is beneficial to improve the detection accuracy by arranging the first detection member 1315 in the structure of the first pressing structure 131 itself. The above configuration is for the pressing action of the first pressing structure 131. Similarly, for the pressing action of the second pressing structure 132, refer to Figure 5 In some embodiments, the second pressing structure 132 further includes a second detecting member 1325. The second pressing structure 132 is suitable for pressing a side of the second position-limiting portion 223 and has a second detecting hole 1324. The second detecting member 1325 is disposed in the second detecting hole 1324 so that the second detecting member 1325 can detect the position of the second position-limiting portion 223. It can be understood that the configuration of the second detecting member 1325 is similar to that of the first detecting member 1315, except that the objects to be detected are different. Therefore, the configuration of the second detecting member 1325 can refer to the configuration of the first detecting member 1315, and has the same effect as the configuration of the first detecting member 1315.

Referring to the reference orientation, the carrying surface 211 can be located on the upper side of the base 210. The base 210 is also provided with a limiting groove 212, and the limiting groove 212 is used to install the limiting component 220 and the locking component 230. It should be noted that the limiting groove 212 can be arranged throughout the carrying surface 211. In other words, the limiting groove 212 can be recessed in the carrying surface 211.

The limiting component 220 includes a first limiting portion 222 and a second limiting portion 223. Corresponding to the first limiting portion 222 and the second limiting portion 223, the electric energy meter may include a first electric energy meter and a second electric energy meter (when the limiting component 220 includes other limiting portions, the electric energy meter adapted thereto may also include other electric energy meters). Among them, the first limiting portion 222 and the second limiting portion 223 are used to limit the first electric energy meter and the second electric energy meter, respectively. Therefore, the shapes of the first limiting portion 222 and the second limiting portion 223 can be set according to the appearance of the first electric energy meter and the second electric energy meter, and the shape or size between the first limiting portion 222 and the second limiting portion 223 can be the same or different. In order to improve the flexibility of the use of the limiting assembly 220 in different limiting scenarios, the first limiting portion 222 and the second limiting portion 223 can be detachably connected to the base 210. For the application scenarios of the detachable connection of the first limiting portion 222 and the second limiting portion 223, please refer to the following text. Exemplarily, the detachable connection between the first limiting portion 222 and the second limiting portion 223 and the base 210 can be any one of a snap connection, a nested connection, a magnetic connection, and a threaded connection.

[0037] Reference Figure 10-12 , the relative arrangement of the limiting assembly 220 and the base 210 is described below. The first limiting portion 222 has a first position accommodated in the limiting groove 212 and a second position at least partially extending out of the limiting groove 212. When the first limiting portion 222 is in the second position, it is used to position the first electric energy meter carried on the carrying surface 211. Specifically, when in the first position, the first limiting portion 222 can be accommodated in the limiting groove 212, that is, the limiting assembly 220 will not interfere with other electric energy meters. When in the second position, the first limiting portion 222 can at least partially extend out of the limiting groove 212, so that the limiting assembly 220 can limit the first electric energy meter and ensure the stability of the tray assembly 20 carrying the electric energy meter. Similarly, the second limiting portion 223 has a third position accommodated in the limiting groove 212 and a fourth position at least partially extending out of the limiting groove 212. When the second limiting portion 223 is in the fourth position, it is used to position the second electric energy meter carried on the carrying surface 211. The configuration of the second limiting portion 223 may refer to the configuration of the first limiting portion 222 in the above embodiment, and will not be described in detail here.

[0038] Reference Figure 10-12The locking assembly 230 is used to lock the limiting assembly 220 at a specific position. The locking assembly 230 includes a first locking portion 231 and a second locking portion 232. The first locking portion 231 and the second locking portion 232 are both arranged in the limiting groove 212 and connected to the base 210. The limiting assembly 220 may be provided with a structure corresponding to the locking assembly 230. Taking the first limiting portion 222 as an example, the first limiting portion 222 may include a locking portion 221. The locking portion 221 is used to cooperate with the first locking portion 231 and be locked by the first locking portion 231. The locking portion 221 set as above is used as an example in the following description.

[0039] For the position switching process of the limit assembly 220, refer to Figure 11-Figure 12 , taking the first limiting portion 222 as an example, when the first limiting portion 222 is not needed for limiting, the first limiting portion 222 can be switched from the second position to the first position. During the process of the first limiting portion 222 switching its position, the first limiting portion 222 once presses against the first locking portion 231, so that the first locking portion 231 is fixedly connected to the first limiting portion 222, thereby keeping the first limiting portion 222 in the first position, that is, it can effectively prevent the first limiting portion 222 from extending out of the limiting slot 212 to interfere with other electric energy meters. Similarly, during the process of the second limiting portion 223 switching from the fourth position to the third position, the second limiting portion 223 once presses against the second locking portion 232, so that the second locking portion 232 is fixedly connected to the second limiting portion 223, thereby keeping the second limiting portion 223 in the third position, that is, it can effectively prevent the second limiting portion 223 from extending out of the limiting slot 212 to interfere with other electric energy meters. In contrast to the process of switching the limiting portion in the limiting position to the retracted position, when the limiting portion in the retracted state needs to play a limiting effect, the limiting portion can at least partially pop out of the limiting groove 212 after being pressed. Specifically, refer to Figure 12-Figure 11 When the first limiting portion 222 is in the first position and presses the first locking portion 231 twice, the first limiting portion 222 can move to the second position to achieve the limiting fixation of the first electric energy meter. When the second limiting portion 223 is in the third position and presses the second locking portion 232 twice, the second limiting portion 223 can move to the fourth position.

[0040] Reference Figure 8-Figure 13, the specific driving setting of the limiting assembly 220 is introduced below. In some embodiments, the tray assembly 20 includes a first elastic member 240, and the two ends of the first elastic member 240 are respectively connected to the base 210 and the first limiting portion 222, that is, the first limiting portion 222 can switch its position relative to the base 210 using the elastic force provided by the first elastic member 240. Specifically, when the locking portion 221 of the first limiting portion 222 presses the first locking portion 231 once, the first elastic member 240 is compressed, so as to drive the first limiting portion 222 to switch from the first position to the second position after the first locking portion 231 releases the locking portion 221. In other embodiments, the tray assembly 20 includes a driving rod, and the two ends of the driving rod are respectively connected to the base 210 and the first limiting portion 222. The driving rod can be provided with a sensor, and the locking portion 221 can be sensed by the sensor when it presses against the first locking portion 231 once. After the first locking portion 231 releases the locking portion 221, the driving rod can directly drive the limiting assembly 220 to extend out of the limiting groove 212 and then switch to the second position. The embodiment of the present invention is described by taking the tray assembly 20 provided with a first elastic member 240 as an example. It should be noted that the tray assembly 20 can be provided with a plurality of first elastic members 240, and two adjacent first elastic members 240 can be arranged at intervals. Each first elastic member 240 can provide elastic force for the movement of the limiting assembly 220, thereby ensuring the reliability of the movement of the limiting assembly 220. The tray assembly 20 of this solution can use the elastic force of the first elastic member 240 to drive the limiting assembly 220 to move and reset. The overall structure is simple and the position switching operation is convenient and quick, which can ensure the stability of the position switching. Similarly, in some embodiments, the tray assembly 20 includes a second elastic member 250, and two ends of the second elastic member 250 are respectively connected to the base 210 and the first limiting portion 222, that is, the second limiting portion 223 can switch its position relative to the base 210 using the elastic force provided by the second elastic member 250. The relevant configuration of the second elastic member 250 can refer to the relevant configuration of the first elastic member 240 in the above embodiment, and will not be repeated here.

[0041] The specific limiting settings of the limiting assembly 220 for various types of electric energy meters are introduced below. The first limiting portion 222 is used to separate the bearing surface 211 into a first bearing area, and the first bearing area is suitable for accommodating the first electric energy meter. Similarly, the second limiting portion 223 is used to separate the bearing surface 211 into a second bearing area, and the second bearing area is suitable for accommodating the second electric energy meter. It can be understood that the first limiting portion 222 and the second limiting portion 223 can limit the first electric energy meter and the second electric energy meter respectively to ensure the stability of the first electric energy meter and the second electric energy meter. Taking the first limiting portion 222 as an example, it should be noted that the first limiting portion 222 can separate the bearing surface 211 into multiple first bearing areas, so as to increase the carrying capacity of the tray assembly 20.

[0042] Further, the first limiting portion 222 can be a limiting grid frame 2221, and the limiting grid frame 2221 can adapt to the structure of a single-phase electric meter to achieve stable limiting of the first electric energy meter. Specifically, the limiting grid frame 2221 can fix multiple first electric energy meters at the same time. The second limiting portion 223 has a first limiting block 2231 and a second limiting block 2232 arranged at intervals, and the first limiting block 2231 and the second limiting block 2232 can adapt to the structure of the second electric energy meter to achieve stable limiting of the three-phase electric energy meter. Specifically, the first limiting block 2231 and the second limiting block 2232 can fix multiple second electric energy meters at the same time.

[0043] In addition, in some embodiments, the first electric energy meter is one of a single-phase electric energy meter, a three-phase electric energy meter, and a terminal electric energy meter, and the second electric energy meter is one of the other two of the single-phase electric energy meter, the three-phase electric energy meter, and the terminal electric energy meter. For the above definition, exemplarily, when the first electric energy meter is a single-phase electric energy meter, the second electric energy meter is any one of a three-phase electric energy meter and a terminal electric energy meter. Furthermore, in some embodiments, the structure of the limiting assembly 220 for limiting the electric energy meter only includes the first limiting portion 222 and the second limiting portion 223, that is, the tray assembly 20 can be only suitable for placing two types of electric energy meters (it can place two types of electric energy meters at the same time, or it can only place one type of electric energy meter at the same time); in other embodiments, the limiting assembly 220 also includes a third limiting portion, and the third limiting portion is used to position the third electric energy meter carried on the carrying surface 211, that is, the function of the third limiting portion is similar to that of the first limiting portion 222 and the second limiting portion 223, and the only difference is that the types of electric energy meters to be positioned are different, so that the setting of the third limiting portion can refer to the relevant settings of the first limiting portion 222 and the second limiting portion 223 in various embodiments of the present invention. When the third limiting portion is provided, the first limiting portion 222, the second limiting portion 223, and the third limiting portion can each be responsible for positioning one of the single-phase electric meter, the three-phase electric meter and the terminal electric meter.

[0044] In addition, in some embodiments, the tray system may include a conveying assembly, which is configured to drive the tray assembly 20 to move, specifically to drive the tray assembly 20 to move to different workstations. For example, the tray assembly 20 can be driven around the pressing device 100, or driven to an electric energy meter detection station.

[0045] The third aspect of the present invention also provides a tray control method, which is applied to the tray system of any of the above embodiments. At the same time, the first pressing structure 131 also includes a first detection member 1315, and the second pressing structure 132 also includes a second detection member 1325. The first detection member 1315 and the second detection member 1325 are used to detect the positions of the first limit portion 222 and the second limit portion 223, respectively. For the settings of the first detection member 1315 and the second detection member 1325, reference can be made to the relevant descriptions of the above embodiments, which will not be repeated here. Fig.14The tray control method includes but is not limited to the following steps: S101: Control the first cylinder 121 and drive the first pressing structure 131 to press the first position-limiting portion 222 or control the second cylinder 122 and drive the second pressing structure 132 to press the second position-limiting portion 223; S102: If the first pressing structure 131 presses the first limiting portion 222, the first detecting member 1315 detects whether the first limiting portion 222 is pressed to the target position; If the second pressing structure 132 presses the second position-limiting portion 223 , the second detecting member 1325 detects whether the second position-limiting portion 223 is pressed to a target position.

[0046] The above steps are further explained below. In step S101, the selection and judgment of controlling the first cylinder 121 or the second cylinder 122 can be based on the structure of the tray assembly 20 or the limit requirement of the tray assembly 20, and can be determined by the pressing device 100 or by the operator. In step S102, the movement method of the pressing device 100, the driving pressing method, and the detection method can all refer to the relevant descriptions of the above embodiments. In addition, if the detection is unqualified, the pressing device 100 can sound an alarm, or automatically perform an additional pressing operation on one side. If the detection is qualified, the pressing operation is completed.

[0047] Thanks to the improvements of the pressing device 100 in the above embodiments, the tray system of the second embodiment and the tray control method of the third embodiment of the present invention have the same technical effects as the pressing device 100 in the above embodiments, which will not be described in detail here.

[0048] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
