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 mounted on it, 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. Integrating these multiple pressing structures into a single component results in a large space requirement and complex design. Summary of the Invention

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.

[0061] 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

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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 mounted on it, 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. Integrating these multiple pressing structures into a single component results in a large space requirement and complex design.

[0066] In view of this, see 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. 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, according to 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 base plate 110, a cylinder assembly 120, and a pressing assembly 130.

[0067] 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 1321 and a second block 1322 for limiting, and the second limiting part 223 includes a second block 1322 and a third block 1323 for limiting. When the first limiting part 222 is in the limiting state (both the first block 1321 and the second block 1322 are raised) and it is necessary to switch to the limiting state of the second limiting part 223 (both the second block 1322 and the third block 1323 are raised), it is only necessary to press and compress the first block 1321 back and press and raise the third block 1323. 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 1321 and a second block 1322 for limiting, and the second limiting portion 223 includes a third block 1323 and a fourth block 1311 for limiting. When the first limiting portion 222 is in the limiting state (both the first block 1321 and the second block 1322 are raised) and it is necessary to switch to the limiting state of the second limiting portion 223 (both the third block 1323 and the fourth block 1311 are raised), it is necessary to press and compress the first block 1321 and the second block 1322 back, and press and raise the third block 1323 and the fourth block 1311.

[0068] For details, see Figures 1-2 as well as Figures 6-7Corresponding to the requirement that the tray assembly 20 needs to be pressed, the first pressing structure 131 is adapted to press the first limiting portion 222 of the tray assembly 20, and the second pressing structure 132 is adapted to press the second limiting portion 223 of the tray assembly 20. Furthermore, depending on the requirements, in some embodiments, in addition to the first and second pressing portions, the base plate 110 of the pressing device 100 can also be connected to other pressing structures, such as a third pressing structure. The third pressing structure is adapted to press the third limiting portion of the tray assembly 20. It is understood that the structure and arrangement of the third pressing structure can be the same as or similar to those of the first pressing structure 131 and the second pressing structure 132; the difference may lie only in the target pressing structure or position.

[0069] See Figures 1-2 as well as Figures 6-7 To drive the first or second pressing part to perform a pressing operation, the cylinder assembly 120 is connected to the base plate 110. 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 limiting part 222, and the second cylinder 122 is configured to drive the second pressing structure 132 to press the second limiting part 223. Both the first cylinder 121 and the second cylinder 122 can be an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder, and the type or structure of the first cylinder 121 and the second cylinder 122 can be the same or different. With the above configuration, the first cylinder 121 and the second cylinder 122, which serve as the driving source, as well as the first pressing structure 131 and the second pressing structure 132, which serve as the abutment driving components, can all be integrated and connected to the base plate 110. When there is a need to extend or retract the first pressing structure 131 and the second pressing structure 132 relative to each other under different conditions, the pressing device 100 of the present invention has a high degree of integration and a simple structure. Furthermore, the first pressing structure 131 and the second pressing structure 132 can move simultaneously in opposite directions, i.e., while one is extending, the other is retracting, thereby making the state switching speed faster and the working efficiency higher. In order to enable the pressing device 100 to align with the tray assembly 20, in some embodiments, the pressing device 100 may include a driving component. The driving component can drive the base plate 110 to move relative to the tray assembly 20. The driving device can be connected only to the base plate 110 to indirectly drive the cylinder assembly 120 and the pressing component 130, making the driving method more efficient.

[0070] In the technical solution of the present invention, the pressing device 100 includes a base plate 110, a cylinder assembly 120, and a pressing assembly 130. Corresponding to the requirement that the tray assembly 20 needs to be pressed, a first pressing structure 131 is adapted to press the first limiting portion 222 of the tray assembly 20, and a second pressing structure 132 is adapted to press the second limiting 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 limiting portion 222, and the second cylinder 122 is configured to drive the second pressing structure 132 to press the second limiting portion 223. Compared to related technologies that treat various pressing structures as separate parts and use them separately for pressing, or methods involving manual pressing, 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 achieves higher integration and higher pressing operation efficiency.

[0071] For ease of description, the cylinder body referred to below refers to the first cylinder body 121 and / or the second cylinder body 122, the pressing structure refers to the first pressing structure 131 and / or the second pressing structure 132, and the limiting part refers to the first limiting part 222 and / or the second limiting part 223.

[0072] For details on the pressing mechanism, please refer to [link / reference]. Figures 1-3 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. Both the first and second pressing blocks can have any suitable shape and arrangement. Furthermore, for the first pressing blocks, each first pressing block can be integrally connected, meaning each integrally connected first pressing block can be a part of an integral structure, and the extension directions of the first pressing blocks can be different. The second pressing blocks can be arranged similarly. The pressing assembly 130 includes a first plate 133 and a second plate 134. A first cylinder 121 is connected to one side of the first plate 133, and each first pressing block is connected to the other side. A second cylinder 122 is connected to one side of the second plate 134, and each second pressing block is connected to the other side. Taking the configuration 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 of the first pressing blocks, which can improve the integration of the pressing device 100. Furthermore, the first cylinder 121 and each of the first pressing blocks are respectively connected to both sides of the first plate 133, which can prevent the configuration and movement of the first cylinder 121 from affecting the arrangement and pressing action of each of the first pressing blocks. The configuration of the second plate 134 has the same effect as that of the first plate 133. Depending on the requirements, in some other embodiments, the first pressing structure 131 may include only one first pressing block, or the second pressing structure 132 may include only one second pressing block.

[0073] When multiple first pressing blocks and second pressing blocks are provided according to the above embodiments, in order to avoid interference between the first pressing blocks and the second pressing blocks, see [reference needed]. Figures 1-3 In some embodiments, along the driving direction of the first cylinder 121, the first plate 133 is disposed between the base plate 110 and the second plate 134, that is, the first plate 133 and the second plate 134 are stacked sequentially on the same side of the base plate 110. In order to avoid the extension and retraction of the first cylinder 121 connected to the first plate 133 being interfered with by each of the second pressing blocks or the second plate 134, each of the second pressing blocks and the second plate 134 together form a relief groove 135. The first cylinder 121 can drive each of the first pressing blocks to extend at least partially out of the relief groove 135.

[0074] For details regarding the clearance groove 135 described above, please refer to [link / reference]. Figures 1-3 In 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 a first block 1321, a second block 1322, and a third block 1323. The first pressing block includes a fourth block 1311, a fifth block 1312, and a 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 and the second block 1322 are spaced apart to form a first groove 1351, and the other side is provided with a 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 separates and defines the second groove 1352 and the third groove 1353 on both sides of the first block 1321. The first groove 1351, the second groove 1352, and the third groove 1353 defined above provide telescopic clearance space for the fourth block 1311, the fifth block 1312, and the sixth block 1313, respectively. The first cylinder 121 can drive the fourth block 1311 to extend at least partially out of the first groove 1351, drive the fifth block 1312 to extend at least partially out of the second groove 1352, and drive the sixth block 1313 to extend at least partially out of the third groove 1353. Furthermore, see... Figures 1-3 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 axis of symmetry. 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 axis of symmetry. This arrangement of the blocks fully utilizes the structure of each second pressing block and the second plate 134 to form the clearance groove 135. The clearance groove 135 is rationally distributed, with high space utilization, allowing the first and second pressing blocks to be more closely spaced and adapting to complex scenarios where pressing positions intersect under different requirements.

[0075] Based on multiple first pressing blocks, the configuration of the first cylinder 121 is as follows: in some embodiments, there are multiple first cylinders 121, which can drive each first pressing block one by one; in other embodiments, at least one first cylinder 121 (which can be one or more first cylinders 121) can drive multiple first pressing blocks simultaneously. Similarly, the second cylinder 122 can also be configured in the same way.

[0076] To improve the pressing effect of the pressing structure on the limiting part, refer to Figure 4 In some embodiments, the first pressing structure 131 further includes a first detection element 1315. The first pressing structure 131 is adapted to press one side of the first limiting portion 222 and has a first detection hole 1314. The cross-section of the first detection hole 1314 can be of any suitable shape. The first detection element 1315 is disposed within the first detection hole 1314 so that the first detection element 1315 can detect the position of the first limiting portion 222. It is understood that after the first detection element 1315 is disposed within the first detection hole 1314, the first detection element 1315 can pass through the first detection hole 1314 toward the first limiting portion 222, thereby detecting whether the first limiting portion 222 has been pressed to the target position by the first pressing structure 131. The detection method can be any suitable detection method such as laser, infrared sensing, or visual sensing. By disposing the first detection element 1315 within the structure of the first pressing structure 131 itself, it is beneficial to improve the detection accuracy. The above settings are 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 detection element 1325. The second pressing structure 132 is adapted to press one side of the second limiting portion 223 and has a second detection hole 1324. The second detection element 1325 is disposed within the second detection hole 1324 so that the second detection element 1325 can detect the position of the second limiting portion 223. It is understood that the setting of the second detection element 1325 is similar to that of the first detection element 1315, the difference being that the object being detected is different. Therefore, the setting of the second detection element 1325 can refer to the setting of the first detection element 1315 described above, and has the same effect as the setting of the first detection element 1315.

[0077] 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.

[0078] Reference Figures 8-13The base 210 is used to support the electricity meter. Specifically, one side of the base 210 has a support surface 211 for supporting the electricity meter. Referring to the orientation, the support 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 support surface 211. In other words, the limiting groove 212 can be recessed into the support surface 211.

[0079] Reference Figures 8-9 The 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.

[0080] Reference Figures 10-12The 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.

[0081] Reference Figures 10-12 The 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.

[0082] For the position switching process of the limit component 220, refer to the following steps: Figures 11-12Taking 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] In addition, 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.

[0088] 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 structure 131 further includes a first detection element 1315, and the second pressing structure 132 further includes a second detection element 1325. The first detection element 1315 and the second detection element 1325 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 1315 and the second detection element 1325 can be referred to the relevant descriptions of the foregoing embodiments, and will not be repeated here. See also... Figure 14The tray control method includes, but is not limited to, the following steps:

[0089] S101: Control the first cylinder 121 and drive the first pressing structure 131 to press the first limiting part 222, or control the second cylinder 122 and drive the second pressing structure 132 to press the second limiting part 223;

[0090] S102: If the first pressing structure 131 presses the first limiting part 222, the first detection element 1315 detects whether the first limiting part 222 has been pressed to the target position;

[0091] If the second pressing structure 132 presses the second limiting part 223, the second detection element 1325 detects whether the second limiting part 223 has been pressed to the target position.

[0092] The above steps are further explained below. In step S101, the selection of controlling the first cylinder 121 or the second cylinder 122 can be determined based on the structure of the tray assembly 20 or the limiting requirements of the tray assembly 20, and can be determined by the pressing device 100 or by the operator. In step S102, the movement mode, driving pressing mode, and detection mode of the pressing device 100 can all refer to the relevant descriptions of the above embodiments. In addition, 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.

[0093] 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.

[0094] 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.
