Description

Technical Field

[0001] This invention relates to the field of energy meter tray control technology, and in particular to a pressing device, tray system and tray control method for a calibration device. Background Technology

[0002] The tray assembly is used to support electricity meters and perform assembly line testing. Existing tray assemblies include a base and a limiting part. The limiting part is located on the base to limit and fix the electricity meter supported on the base, thereby ensuring the stability of the meter's fixation. Electricity meters include various types such as single-phase meters, three-phase meters, and terminal meters. In related technologies, multiple limiting parts are simultaneously set on the tray assembly to accommodate different types of meters. However, multiple pressing structures are also required for each of these limiting parts. In this case, each pressing structure is designed as a different part and manually switched, resulting in cumbersome operation. Summary of the Invention

[0003] The main objective of this invention is to provide a pressing device, a tray system, and a tray control method for a calibration device, which makes the pressing operation more convenient and flexible.

[0004] To achieve the above objectives, the embodiments of the present invention adopt the following technical solutions:

[0010] In some embodiments, the pressing robot includes a rotating assembly and a robot body. The rotating assembly is configured to drive the robot body to rotate about a first axis relative to the tray assembly. The robot body includes a robotic arm assembly and a drive assembly. The robotic arm assembly is used to connect to the first pressing part or the second pressing part. The drive assembly is configured to drive the robotic arm assembly to rotate about a second axis, wherein the first axis is perpendicular to the second axis.

[0011] In some embodiments, the pressing device further includes a placement platform that can be disposed on one side of the tray assembly, wherein the first pressing part and the second pressing part are both placed on the placement platform, and the first pressing part, the second pressing part and the tray assembly are distributed circumferentially around the first axis.

[0012] In some embodiments, the first pressing part includes a first base plate and a first quick-change disc, the first pressing structure is connected to one side of the first base plate and the first quick-change disc is connected to the other side of the first base plate, the second pressing part includes a second base plate and a second quick-change disc, the second pressing structure is connected to one side of the second base plate and the second quick-change disc is connected to the other side of the second base plate, and the pressing robot includes a third quick-change disc, which can be detachably installed on the first quick-change disc or the second quick-change disc.

[0013] In some embodiments, the first pressing portion further includes a first detection element, the first pressing structure is adapted to press one side of the first limiting portion having a first detection hole, and the first detection element is disposed within the first detection hole so that the first detection element can detect the position of the first limiting portion;

[0015] The second pressing part further includes a second detection element. The second pressing structure is adapted to press one side of the second limiting part and has a second detection hole. The second detection element is disposed within the second detection hole so that the second detection element can detect the position of the second limiting part.

[0016] A second aspect of the present invention also provides a tray system including a pressing device of any of the above embodiments; and the tray assembly for carrying the electricity meter.

[0017] In some embodiments, the tray assembly includes a base, a limiting component, and a locking component, and the energy meter includes a first energy meter and a second energy meter;

[0018] The base has a bearing surface on one side for supporting the electricity meter, and the base is provided with a limiting groove penetrating the bearing surface. The limiting component includes a first limiting part and a second limiting part, both of which are connected to the base. The first limiting part has a first position accommodated within the limiting groove and a second position at least partially extending out of the limiting groove. The second limiting part has a third position accommodated within the limiting groove and a fourth position at least partially extending out of the limiting groove. When the first limiting part is in the second position, it is used to position the first electricity meter supported on the bearing surface. When the second limiting part is in the fourth position, it is used to position the second electricity meter supported on the bearing surface. The locking component includes a first locking part and a second locking part, both of which are disposed within the limiting groove and connected to the base.

[0019] During the process of the first limiting part switching from the second position to the first position, the first limiting part presses the first locking part once to fix the first locking part to the first limiting part, thereby keeping the first limiting part in the first position; during the process of the second limiting part switching from the fourth position to the third position, the second limiting part presses the second locking part once to fix the second locking part to the second limiting part, thereby keeping the second limiting part in the third position; when the first limiting part is in the first position and the first locking part is pressed a second time, the first limiting part can move to the second position; when the second limiting part is in the third position and the second locking part is pressed a second time, the second limiting part can move to the fourth position.

[0020] In some embodiments, the tray assembly includes a first elastic member and a second elastic member. The two ends of the first elastic member are respectively connected to the base and the first limiting part. When the first limiting part presses the first locking part once, the first elastic member is compressed. After the first limiting part presses the first locking part a second time, the first elastic member releases its elastic force and drives the first limiting part to switch from the first position to the second position. The two ends of the second elastic member are respectively connected to the base and the second limiting part. When the first limiting part presses the first locking part once, the first elastic member is compressed. After the second limiting part presses the second locking part a second time, the second elastic member releases its elastic force and drives the second limiting part to switch from the third position to the fourth position.

Using a pallet system according to any of the above embodiments, the first pressing part further includes a first detection element for detecting the position of the first limiting part, and the second pressing part further includes a second detection element for detecting the position of the second limiting part. The pallet control method includes:

[0023] The pressing device is controlled to connect to either the first pressing part or the second pressing part;

[0024] If the pressing device is connected to the first pressing part, the pressing device is controlled to move above the tray assembly, and the first pressing part is driven to press the first limiting part. The first detection element detects whether the first limiting part is pressed to the target position.

[0025] If the pressing device is connected to the second pressing part, the pressing device is controlled to move above the tray assembly, and the second pressing part is driven to press the second limiting part. The second detection element detects whether the second limiting part is pressed to the target position.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] The pressing device includes a pressing robot, a first pressing part, and a second pressing part. The first pressing part and the second pressing part are used in scenarios where a first limiting part needs to be pressed and a second limiting part needs to be pressed, respectively. The pressing robot is configured to move relative to the tray assembly. The pressing robot is configured to connect to the first pressing part and drive the first pressing structure to press the first limiting part, or connect to the second pressing part and drive the second pressing structure to press the second limiting part.

[0057] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0058] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0059] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0060] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0061] The tray assembly is used to support electricity meters and perform assembly line testing. Existing tray assemblies include a base and a limiting part. The limiting part is located on the base to limit and fix the electricity meter supported on the base, thereby ensuring the stability of the meter's fixation. Electricity meters include various types such as single-phase meters, three-phase meters, and terminal meters. In related technologies, multiple limiting parts are simultaneously set on the tray assembly to accommodate different types of meters. However, multiple pressing structures are also required for each of these limiting parts. In this case, each pressing structure is designed as a different part and manually switched, resulting in cumbersome operation.

[0062] In view of this, refer to Figures 1-13This invention provides a pressing device 100 for controlling a tray assembly 20. The tray assembly 20 carries an electricity meter and performs automated testing on the meter. The tray assembly 20 may include a base 210, a first limiting part 222, and a second limiting part 223. The first limiting part 222 and the second limiting part 223 are respectively disposed on the base 210 and respectively limit and fix two types of electricity meters carried on the base 210, thereby ensuring the stability of the electricity meter fixation. Electricity meters include various types such as single-phase meters, three-phase meters, and terminal meters. Therefore, depending on the requirements, it is necessary to press the first limiting part 222 and the second limiting part 223, and make the remaining limiting parts protrude from the base 210 to achieve a limiting function. The pressing device 100 of this invention serves to press the first limiting part 222 and the second limiting part 223. Specifically, the pressing device 100 includes a pressing robot 110, a first pressing part 120, and a second pressing part 130. Corresponding to the first limiting part 222 that needs to be pressed, the first pressing part 120 includes a first pressing structure 121, which is adapted to press the first limiting part 222 of the tray assembly 20. Similarly, corresponding to the second limiting part 223 that needs to be pressed, the second pressing part 130 includes a second pressing structure 131, which is adapted to press the second limiting part 223 of the tray assembly 20. It is understood that the first pressing part 120 and the second pressing part 130 can serve as replaceable tool modules, used respectively for scenarios requiring pressing the first limiting part 222 and the second limiting part 223.

[0063] It should be noted that, in some embodiments, the structure of the limiting part (first limiting part 222, second limiting part 223, etc.) of the tray assembly 20 described in this invention may have overlapping parts. For example, the first limiting part 222 includes a first block and a second block for limiting, and the second limiting part 223 includes a second block and a third block for limiting. When the first limiting part 222 is in the limiting state (both the first block and the second block are raised) and it is necessary to switch to the limiting state of the second limiting part 223 (both the second block and the third block are raised), it is only necessary to press and compress the first block back and press and raise the third block. In other embodiments, the structures of the limiting portions of the tray assembly 20 may not overlap. For example, the first limiting portion 222 includes a first block and a second block for limiting, and the second limiting portion 223 includes a third block and a fourth block for limiting. When the first limiting portion 222 is in the limiting state (both the first block and the second block are raised) and it is necessary to switch to the limiting state of the second limiting portion 223 (both the third block and the fourth block are raised), it is necessary to press and compress the first block and the second block back, and press and raise the third block and the fourth block.

[0064] Reference Figures 1-4To drive the first pressing part 120 or the second pressing part 130 to perform a pressing operation, the pressing robot 110 is configured to move relative to the tray assembly 20. The pressing robot 110 is configured to connect to the first pressing part 120 and drive the first pressing structure 121 to press the first limiting part 222, or connect to the second pressing part 130 and drive the second pressing structure 131 to press the second limiting part 223. This driving pressing method allows the pressing robot 110 to selectively connect to the first pressing part 120 or the second pressing part 130 as needed, achieving the corresponding pressing effect. This solution eliminates the need for manual pressing. Users can replace the first pressing part 120 or the second pressing part 130 as needed to adapt to more diverse requirements without affecting the pressing robot 110, thus making the pressing operation more convenient and flexible. Furthermore, depending on the requirements, in some embodiments, the pressing device 100 may be provided with other pressing parts in addition to the first pressing part 120 and the second pressing part 130, such as a third pressing part. The third pressing part includes a third pressing structure, which is adapted to press the third limiting part of the tray assembly 20. It is understood that the structure and arrangement of the third pressing part may be the same as or similar to those of the first pressing part 120 and the second pressing part 130, and the difference may only be that the target pressing structure or position is different.

[0065] In the technical solution of the present invention, the pressing device 100 includes a pressing robot 110, a first pressing part 120, and a second pressing part 130. The first pressing part 120 and the second pressing part 130 are respectively used in scenarios where the first limiting part 222 needs to be pressed and the second limiting part 223 needs to be pressed. The pressing robot 110 is configured to move relative to the tray assembly 20. The pressing robot 110 is configured to connect to the first pressing part 120 and drive the first pressing structure 121 to press the first limiting part 222, or connect to the second pressing part 130 and drive the second pressing structure 131 to press the second limiting part 223. The pressing device 100 of the present invention drives the pressing robot 110 to selectively connect to the first pressing part 120 or the second pressing part 130 as needed, and perform the corresponding pressing function. This solution eliminates the need for manual pressing. Users can replace the first pressing part 120 or the second pressing part 130 as needed to adapt to more diverse requirements, without affecting the pressing robot 110. Therefore, the pressing device 100 of the present invention makes the pressing operation more convenient and flexible.

[0066] For ease of description, the pressing part described below refers to the first pressing part 120 and / or the second pressing part 130, the pressing structure refers to the first pressing structure 121 and / or the second pressing structure 131, and the limiting part refers to the first limiting part 222 and / or the second limiting part 223.

[0067] For the specific structure of the pressing robot 110, refer to Figure 1 In some embodiments, the pressing robot 110 includes a rotating assembly 111 and a robot body 112. The rotating assembly 111 is configured to drive the robot body 112 to rotate relative to the tray assembly 20 about a first axis L1. The robot body 112 includes a robotic arm assembly 1121 and a drive assembly 1122. The robotic arm assembly 1121 is used to connect to a first pressing part 120 or a second pressing part 130. The drive assembly 1122 is configured to drive the robotic arm assembly 1121 to rotate about a second axis L2, where the first axis L1 is perpendicular to the second axis L2. To achieve the pressing operation, the robotic arm may include multiple arm-like structures rotatably connected to each other, or the robotic arm may include a telescopic structure. It is understood that the robot body 112 is used to connect to the pressing part and drive the pressing part to perform the pressing operation. The rotating assembly 111 can drive to change the orientation of the robot body 112, so that the robot body 112 can switch between a state of switching between connecting to the first pressing part 120 or the second pressing part 130 and a state of pressing the tray assembly 20.

[0068] Furthermore, refer to Figure 1 In some embodiments, the pressing device 100 further includes a placement platform 140, which can be disposed on one side of the tray assembly 20. Both the first pressing part 120 and the second pressing part 130 are placed on the placement platform 140. Placing the first pressing part 120 and the second pressing part 130 on the placement platform 140 facilitates the picking and placing operations of the pressing robot 110 and the operator. (Refer to...) Figure 1The placement platform 140 can be provided with placement supports corresponding to the first pressing part 120 and the second pressing part 130. The placement supports can support the first pressing part 120 and the second pressing part 130 to facilitate the grasping operation of the pressing robot 110. In some embodiments, the first pressing part 120, the second pressing part 130 and the tray assembly 20 are distributed circumferentially around the first axis L1. The first axis L1 is the rotation axis of the pressing robot 110 (rotating component 111). The above arrangement aligns the distribution direction of the first pressing part 120, the second pressing part 130, and the tray component 20 with the rotation direction of the pressing robot 110. This reduces the rotation amplitude of the robot body 112 when switching between the first pressing part 120 and the second connecting part, thereby increasing the working efficiency of the pressing robot 110. At the same time, it can also reduce the adjustment amplitude of the pressing robot 110 during the connection switching process (or eliminate the need for adjustment). Specifically, in some embodiments, based on the above circumferential distribution arrangement, the robot body 112 only needs to reciprocate along the circumferential direction during the connection switching process, without adjusting its position in other directions (such as the front-back direction), thus improving operational accuracy and efficiency. It should be noted that the aforementioned circumferential distribution along the first axis L1 only indicates the direction of distribution and does not limit the specific distribution trajectory. That is, the line connecting the geometric centers of the first pressing part 120, the second pressing part 130, and the tray assembly 20 can be a curved broken line or a straight line. Specifically, refer to... Figure 1 In some embodiments, the pressing robot 110, the first pressing part 120 and the second pressing part 130 may all be located on the same side of the tray assembly 20 along the circumferential direction, and the first pressing part 120 and the second pressing part 130 are arranged in front of the pressing robot 110 along the circumferential direction.

[0069] For the connection structure of the pressing robot 110 to the first pressing part 120 or the second pressing part 130, refer to Figure 1 and Figure 7In some embodiments, the first pressing part 120 includes a first base plate 122 and a first quick-change disc 123. A first pressing structure 121 is connected to one side of the first base plate 122, and the first quick-change disc 123 is connected to the other side of the first base plate 122. The second pressing part 130 includes a second base plate 132 and a second quick-change disc 133. The second pressing structure 131 is connected to one side of the second base plate 132, and the second quick-change disc 133 is connected to the other side of the second base plate 132. The pressing robot 110 includes a third quick-change disc 113, which can be detachably installed on either the first quick-change disc 123 or the second quick-change disc 133. It is understood that the third quick-change disc 113 can be connected to either the first quick-change disc 123 or the second quick-change disc 133 as needed, enabling rapid replacement of the end effector of the pressing robot 110. In addition to the pressing part, the end effector can also be compatible with other tools, such as welding guns, spray guns, suction cups, grippers, etc. (the pressing device 100 may also include the aforementioned tools). Through this cooperation, it is possible to quickly connect or disconnect between different tasks without requiring manual labor to perform complex tool disassembly and installation operations on the robot for a long time.

[0070] Reference Figures 2-7 In some embodiments, the first base plate 122 or the second base plate 132 may have through holes, which can be used to avoid the structure of the limiting part, or to reduce weight and manufacturing costs.

[0071] The specific structure and mating configuration of the first quick-change disc 123, the second quick-change disc 133, and the third quick-change disc 113 are as follows: In some embodiments, the structure between the first quick-change disc 123 and the second quick-change disc 133, and their respective connection configurations with the third quick-change disc 113, can be the same or different. The following description uses the same embodiment as an example, focusing on the mating configuration of the first quick-change disc 123 and the third quick-change disc 113. The first quick-change disc 123 and the third quick-change disc 113 can have mutually matching interfaces and connecting components. Specifically, in some embodiments, the connection structure between the first quick-change disc 123 and the third quick-change disc 113 can be one of a bayonet structure, a pin structure, a magnetic structure, a threaded structure, or a spring structure. In some embodiments, after the first quick-change disc 123 and the third quick-change disc 113 are mated, an airflow channel can be formed. Airflow entering the airflow channel can generate an adsorption force that attracts the first quick-change disc 123 and the third quick-change disc 113.

[0072] To improve the pressing effect of the pressing structure on the limiting part, refer to Figure 4In some embodiments, the first pressing part 120 further includes a first detection element 124. The first pressing structure 121 is adapted to press one side of the first limiting part 222 and has a first detection hole 1211. The cross-section of the first detection hole 1211 can be of any suitable shape. The first detection element 124 is disposed within the first detection hole 1211 so that the first detection element 124 can detect the position of the first limiting part 222. It can be understood that after the first detection element 124 is disposed within the first detection hole 1211, the first detection element 124 can pass through the first detection hole 1211 toward the first limiting part 222, thereby detecting whether the first limiting part 222 has been pressed to the target position by the first pressing part 120. The detection method can be any suitable detection method such as laser, infrared sensing, or visual sensing. By disposing the first detection element 124 within the structure of the first pressing part 120 itself, it is beneficial to improve the detection accuracy. The above settings are for the pressing action of the first pressing part 120. Similarly, for the pressing action of the second pressing part 130, refer to... Figure 7 In some embodiments, the second pressing portion 130 further includes a second detection element 134. The second pressing structure 131 is adapted to press one side of the second limiting portion 223 and has a second detection hole 1311. The second detection element 134 is disposed within the second detection hole 1311 so that the second detection element 134 can detect the position of the second limiting portion 223. It is understood that the setting of the second detection element 134 is similar to that of the first detection element 124, the difference being that the object being detected is different. Therefore, the setting of the second detection element 134 can refer to the setting of the first detection element 124 described above, and has the same effect as the setting of the first detection element 124.

[0073] Reference Figures 8-13 A second aspect of the present invention also provides a tray system, including a pressing device 100 and a tray assembly 20 as described in any of the foregoing embodiments. The function and related configuration of the tray assembly 20 can be found in the descriptions of the foregoing embodiments, and will not be repeated here.

[0074] Reference Figures 8-13 The substrate 210 is used to support the electricity meter. Specifically, one side of the substrate 210 has a bearing surface 211 for supporting the electricity meter. (Refer to...) Figure 8 The bearing surface 211 can be located on the upper side of the base 210. The base 210 is also provided with a limiting groove 212, which 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 through the bearing surface 211. In other words, the limiting groove 212 can be recessed into the bearing surface 211.

[0075] Reference Figures 8-9The limiting component 220 is used to limit the electricity meter. The limiting component 220 includes a first limiting part 222 and a second limiting part 223. Corresponding to the first limiting part 222 and the second limiting part 223, the electricity meter may include a first electricity meter and a second electricity meter (when the limiting component 220 includes other limiting parts, the electricity meter it is adapted to can also include other electricity meters). The first limiting part 222 and the second limiting part 223 are used to limit the first electricity meter and the second electricity meter, respectively. Therefore, the shapes of the first limiting part 222 and the second limiting part 223 can be set according to the external shape of the first electricity meter and the second electricity meter, and the shapes or sizes of the first limiting part 222 and the second limiting part 223 can be the same or different. To improve the flexibility of the limiting component 220 in different limiting scenarios, both the first limiting part 222 and the second limiting part 223 are detachably connected to the base 210. For application scenarios of the detachable connection of the first limiting part 222 and the second limiting part 223, please refer to the following text. For example, the detachable connection between the first limiting part 222 and the second limiting part 223 and the base 210 can be any of the following: snap-fit ​​connection, nested connection, magnetic connection, or threaded connection.

[0076] Reference Figures 10-12 The relative arrangement of the limiting component 220 and the base 210 is described below. The first limiting part 222 has a first position accommodated within the limiting groove 212 and a second position at least partially extending out of the limiting groove 212. When the first limiting part 222 is in the second position, it is used to position the first energy meter supported on the bearing surface 211. Specifically, when in the first position, the first limiting part 222 can be accommodated within the limiting groove 212, meaning that the limiting component 220 will not interfere with other energy meters. When in the second position, the first limiting part 222 can be arranged to at least partially extend out of the limiting groove 212, thus the limiting component 220 can limit the first energy meter, ensuring the stability of the energy meter supported by the tray assembly 20. Similarly, the second limiting part 223 has a third position accommodated within the limiting groove 212 and a fourth position at least partially extending out of the limiting groove 212. When the second limiting part 223 is in the fourth position, it is used to position the second energy meter supported on the bearing surface 211. The setting of the second limiting part 223 can refer to the relevant setting of the first limiting part 222 in the above embodiment, and will not be repeated here.

[0077] Reference Figures 10-12The locking component 230 is used to lock the limiting component 220 in a specific position. The locking component 230 includes a first locking part 231 and a second locking part 232. Both the first locking part 231 and the second locking part 232 are disposed in the limiting groove 212 and connected to the base 210. The limiting component 220 may have a structure that corresponds to and cooperates with the locking component 230. Taking the first limiting part 222 as an example, the first limiting part 222 may include a locking part 221. The locking part 221 is used to cooperate with the first locking part 231 and is locked by the first locking part 231. The locking part 221 described above will be used as the basis for the following description.

[0078] For the position switching process of the limit component 220, refer to the following steps: Figures 11-12 Taking the first limiting part 222 as an example, when the first limiting part 222 is not needed for limiting, it can switch from the second position to the first position. During the position switching process, the first limiting part 222 presses against the first locking part 231 once, so that the first locking part 231 is fixedly connected to the first limiting part 222, thereby keeping the first limiting part 222 in the first position. This effectively suppresses the first limiting part 222 from extending out of the limiting groove 212 and interfering with other energy meters. Similarly, during the switching process of the second limiting part 223 from the fourth position to the third position, it presses against the second locking part 232 once, so that the second locking part 232 is fixedly connected to the second limiting part 223, thereby keeping the second limiting part 223 in the third position. This effectively suppresses the second limiting part 223 from extending out of the limiting groove 212 and interfering with other energy meters. Conversely, when the limiting part in the limiting position switches to the retracted position, if the limiting part in the retracted state needs to perform a limiting effect, the limiting part can at least partially pop out of the limiting groove 212 after being pressed. Specifically, refer to... Figures 12-11 When the first limiting part 222 is in the first position and presses against the first locking part 231 for the second time, the first limiting part 222 can move to the second position to achieve the limiting and fixing of the first energy meter. When the second limiting part 223 is in the third position and presses against the second locking part 232 for the second time, the second limiting part 223 can move to the fourth position.

[0079] Reference Figures 8-13The specific driving configuration of the limiting component 220 is described below. In some embodiments, the tray assembly 20 includes a first elastic member 240, with its two ends connected to the base 210 and the first limiting portion 222, respectively. That is, the first limiting portion 222 can switch positions 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 against the first locking portion 231, the first elastic member 240 is compressed, so that after the first locking portion 231 releases the locking portion 221, the first limiting portion 222 is driven to switch from a first position to a second position. In other embodiments, the tray assembly 20 includes a driving rod, with its two ends connected to the base 210 and the first limiting portion 222, respectively. The drive rod can be equipped with a sensor. When the locking part 221 presses against the first locking part 231, the sensor can detect this. After the first locking part 231 releases the locking part 221, the drive rod can directly drive the limiting component 220 to extend out of the limiting groove 212 and switch to the second position. This embodiment of the invention uses a tray assembly 20 equipped with a first elastic element 240 as an example. It should be noted that the tray assembly 20 can be equipped with multiple first elastic elements 240, and adjacent first elastic elements 240 can be arranged at intervals. Each first elastic element 240 can provide elastic force for the movement of the limiting component 220, thereby ensuring the reliability of the movement of the limiting component 220. The tray assembly 20 of this solution can use the elastic force of the first elastic elements 240 to drive the limiting component 220 to move and reset. The overall structure is simple, and the position switching operation is convenient and quick, ensuring the stability of the position switching. Similarly, in some embodiments, the tray assembly 20 includes a second elastic member 250, with its two ends connected to the base 210 and the first limiting portion 222, respectively. That is, the second limiting portion 223 can switch positions relative to the base 210 using the elastic force provided by the second elastic member 250. The relevant settings of the second elastic member 250 can refer to the relevant settings of the first elastic member 240 in the above embodiments, and will not be repeated here.

[0080] The following describes the specific limiting settings of the limiting component 220 for various types of energy meters. The first limiting part 222 is used to divide the bearing surface 211 into a first bearing area, which is suitable for accommodating the first energy meter. Similarly, the second limiting part 223 is used to divide the bearing surface 211 into a second bearing area, which is suitable for accommodating the second energy meter. It can be understood that the first limiting part 222 and the second limiting part 223 can respectively limit the first energy meter and the second energy meter, ensuring the stability of supporting the first energy meter and the second energy meter. Taking the first limiting part 222 as an example, it should be noted that the first limiting part 222 can divide the bearing surface 211 into multiple first bearing areas, thereby increasing the load-bearing capacity of the tray assembly 20.

[0081] Furthermore, the first limiting part 222 can be a limiting grid 2221, which can be adapted to the structure of a single-phase meter to achieve stable limiting of the first energy meter. Specifically, the limiting grid 2221 can simultaneously fix multiple first energy meters. The second limiting part 223 has a first limiting block 2231 and a second limiting block 2232 arranged at intervals, which can be adapted to the structure of a second energy meter to achieve stable limiting of a three-phase meter. Specifically, the first limiting block 2231 and the second limiting block 2232 can simultaneously fix multiple second energy meters.

[0082] Furthermore, in some embodiments, the first energy meter is one of a single-phase meter, a three-phase meter, and a terminal meter, and the second energy meter is one of the other two of a single-phase meter, a three-phase meter, and a terminal meter. For the above limitations, exemplarily, when the first energy meter is a single-phase meter, the second energy meter is any one of a three-phase meter and a terminal meter. Furthermore, in some embodiments, the limiting component 220 for limiting the energy meter only includes the first limiting part 222 and the second limiting part 223, that is, the tray component 20 can only be used to place two types of energy meters (it can place two types of energy meters at the same time, or it can only place one type of energy meter at the same time); in other embodiments, the limiting component 220 also includes a third limiting part, which is used to position the third energy meter carried on the bearing surface 211. That is, the function of the third limiting part is similar to that of the first limiting part 222 and the second limiting part 223, the only difference being that the type of energy meter being positioned is different. Therefore, the setting of the third limiting part can refer to the relevant settings of the first limiting part 222 and the second limiting part 223 in various embodiments of the present invention. When the third limiting part is provided, the first limiting part 222, the second limiting part 223, and the third limiting part can each be responsible for positioning one of the single-phase energy meter, the three-phase energy meter, and the terminal energy meter.

[0083] In addition, refer to Figure 1 In some embodiments, the pallet system may include a conveying component configured to drive the pallet assembly 20 to move, specifically to drive the pallet assembly 20 to different workstations, such as driving the pallet assembly 20 to the vicinity of the pressing device 100 or to the electricity meter detection workstation.

[0084] A third aspect of the present invention also provides a tray control method, applying the tray system of any of the above embodiments. The first pressing part 120 further includes a first detection element 124, and the second pressing part 130 further includes a second detection element 134. The first detection element 124 and the second detection element 134 are respectively used to detect the positions of the first limiting part 222 and the second limiting part 223. The configuration of the first detection element 124 and the second detection element 134 can be referred to the relevant descriptions of the foregoing embodiments, and will not be repeated here. (Refer to...) Figure 14 The tray control method includes, but is not limited to, the following steps:

[0085] S101: The control pressing device 100 is connected to the first pressing part 120 or the second pressing part 130;

[0086] S102: If the pressing device 100 is connected to the first pressing part 120, the pressing device 100 is controlled to move above the tray assembly 20, and the first pressing part 120 is driven to press the first limiting part 222. The first detection element 124 detects whether the first limiting part 222 is pressed to the target position.

[0087] If the pressing device 100 is connected to the second pressing part 130, the pressing device 100 is controlled to move above the tray assembly 20, and the second pressing part 130 is driven to press the second limiting part 223. The second detection element 134 detects whether the second limiting part 223 has been pressed to the target position.

[0088] The following provides further explanation of the above steps. In step S101, the selection of connecting the first pressing part 120 or the second pressing part 130 can be determined based on the structure of the tray assembly 20 or the limiting requirements of the tray assembly 20. This selection can be made by the pressing device 100 or by the operator. The pressing device 100 can automatically move and grasp the first pressing part 120 or the second pressing part 130 via programming or a vision detection device. Alternatively, the operator can manipulate the pressing device 100 to grasp the first pressing part 120 or the second pressing part 130, or the operator can manually connect the first pressing part 120 or the second pressing part 130 to the pressing device 100. In step S102, the movement method, pressing method, and detection method of the pressing device 100 can all refer to the relevant descriptions in the above embodiments. Furthermore, if the detection fails, the pressing device 100 can issue an alarm or automatically perform an additional pressing operation on one side. If the detection passes, the pressing operation is completed. After completing a pressing operation, the pressing robot 110 can remain in place or rotate and switch its connected pressing parts according to subsequent pressing needs, in preparation for the next pressing operation.

[0089] Thanks to the improvements made to the pressing device 100 in the above embodiments, the tray system of the second aspect embodiment and the tray control method of the third aspect embodiment of the present invention have the same technical effects as the pressing device 100 in the above embodiments. Further details will not be provided here.

[0090] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
