[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, the various pressing structures are each designed as different parts and switched manually, which will cause cumbersome operation.

[0023] In view of this, refer to Figure 1-Figure 13In an embodiment of the present invention, a pressing device 100 is provided for controlling 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 pressing robot 110, a first pressing portion 120 and a second pressing portion 130. Among them, corresponding to the first limiting portion 222 that needs to be pressed, the first pressing portion 120 includes a first pressing structure 121, and the first pressing structure 121 is suitable for pressing the first limiting portion 222 of the tray assembly 20. Similarly, corresponding to the second limiting portion 223 that needs to be pressed, the second pressing portion 130 includes a second pressing structure 131, and the second pressing structure 131 is suitable for pressing the second limiting portion 223 of the tray assembly 20. It can be understood that the first pressing portion 120 and the second pressing portion 130 can be used as replaceable tool modules, which are used in the use scenarios where the first limiting portion 222 needs to be pressed and the second limiting portion 223 needs to be pressed, respectively.

[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 and a second block for limiting, and the second limiting portion 223 includes a second block and a third block for limiting. When the first limiting portion 222 is in a limiting state (the first block and the second block are both raised) and needs to be switched to the limiting state of the second limiting portion 223 (the second block and the third block are both raised), it is only necessary to press the first block back and press to raise the third block. 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 and a second block for limiting, and the second limiting part 223 includes a third block and a fourth block for limiting. When the first limiting part 222 is in a limiting state (the first block and the second block are both raised) and needs to be switched to the limiting state of the second limiting part 223 (the third block and the fourth block are both raised), it is necessary to press to retract the first block and the second block, and press to raise the third block and the fourth block.

[0025] Reference Figure 1-Figure 4In order to drive the first pressing part 120 or the second pressing part 130 to perform a pressing operation, the pressing robot 110 is configured to be able to move relative to the tray assembly 20. The pressing robot 110 is configured to be able to connect to the first pressing part 120 and drive the first pressing structure 121 to press the first limiting part 222, or to connect to the second pressing part 130 and drive the second pressing structure 131 to press the second limiting part 223. The above-mentioned driving and pressing method allows the pressing robot 110 to select the first pressing part 120 or the second pressing part 130 as required, and play a corresponding pressing role. This solution eliminates the need for manual pressing operations. Users can replace the first pressing part 120 or the second pressing part 130 as required to meet more diverse needs without affecting the pressing robot 110, thereby making the pressing operation more convenient and flexible. In addition, according to 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, and the third pressing part includes a third pressing structure, and the third pressing structure is suitable for pressing the third limiting part of the tray assembly 20. It can be understood that the structure and setting of the third pressing part may be the same or similar to 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.

[0026] In the technical solution of the present invention, the pressing device 100 includes a pressing robot 110, a first pressing portion 120 and a second pressing portion 130. The first pressing portion 120 and the second pressing portion 130 are used in the use scenarios where the first limiting portion 222 and the second limiting portion 223 need to be pressed, respectively. The pressing robot 110 is configured to be able to move relative to the tray assembly 20. The pressing robot 110 is configured to be able to connect to the first pressing portion 120 and drive the first pressing structure 121 to press the first limiting portion 222, or to connect to the second pressing portion 130 and drive the second pressing structure 131 to press the second limiting portion 223. The pressing device 100 of the present invention drives the pressing method so that the pressing robot 110 can select the first pressing part 120 or the second pressing part 130 according to the needs and play the corresponding pressing role. This solution eliminates the manual pressing operation. The user can replace the first pressing part 120 or the second pressing part 130 according to the needs to meet more diverse needs, and it will not affect the pressing robot 110. Therefore, the pressing device 100 of the present invention can make the pressing operation more convenient and flexible.

[0027] For ease of description, the pressing parts described below all refer to the first pressing part 120 and / or the second pressing part 130 , the pressing structures all refer to the first pressing structure 121 and / or the second pressing structure 131 , and the limiting parts all refer to the first limiting part 222 and / or the second limiting part 223 .

[0028] 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 around a first axis L1 relative to the tray assembly 20. The robot body 112 includes a mechanical arm assembly 1121 and a driving assembly 1122. The mechanical arm assembly 1121 is used to connect the first pressing part 120 or the second pressing part 130. The driving assembly 1122 is configured to drive the mechanical arm assembly 1121 to rotate around a second axis L2. The first axis L1 is perpendicular to the second axis L2. In order to achieve the pressing operation, the mechanical arm may include a plurality of arm-shaped structures that are rotatably connected to each other, or the mechanical arm may include a telescopic structure. It can be understood that the robot body 112 is used to connect the pressing part and drive the pressing part to perform the pressing operation. The rotating assembly 111 can drive the robot body 112 to change its orientation, so that the robot body 112 can switch between the state of switching the connection to the first pressing part 120 or the second pressing part 130 and the state of pressing the tray assembly 20.

[0029] Further, see Figure 1 In some embodiments, the pressing device 100 further includes a placement table 140, which can be disposed on one side of the tray assembly 20, and the first pressing portion 120 and the second pressing portion 130 are both placed on the placement table 140. Placing the first pressing portion 120 and the second pressing portion 130 on the placement table 140 can make it easier for the pressing robot 110 and the operator to pick and place the pressing robot 110, as shown in FIG. Figure 1The placement platform 140 may be provided with placement pillars corresponding to the first pressing part 120 and the second pressing part 130, and the placement pillars may 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 along the circumference around the first axis L1. Among them, the first axis L1 is the rotation axis of the pressing robot 110 (rotating component 111). The above setting is to make the distribution direction of the first pressing part 120, the second pressing part 130 and the tray component 20 correspond to the rotation direction of the pressing robot 110, which is beneficial to reduce the rotation amplitude of the robot body 112 when it is necessary to switch the connection between the first pressing part 120 or the second connection part, that is, to increase 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 switching connection process (or no adjustment is required). Specifically, in some embodiments, according to the above-mentioned circumferential distribution setting, the robot body 112 only needs to rotate back and forth along the circumference during the switching connection, and there is no need to adjust the position along other directions (such as the front and back directions), which improves the operation accuracy and efficiency. It should be noted that the circumferential distribution around the first axis L1 as defined above only indicates the direction of distribution, but does not limit the specific distribution trajectory, that is, the line connecting the geometric centers of the first pressing portion 120, the second pressing portion 130 and the tray assembly 20 can be a curved line or a straight line. Figure 1 In some embodiments, the pressing robot 110, the first pressing part 120 and the second pressing part 130 may 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.

[0030] For the connection structure of the pressing robot 110 and 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 disk 123, the first pressing structure 121 is connected to one side of the first base plate 122, and the first quick-change disk 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 disk 133, the second pressing structure 131 is connected to one side of the second base plate 132, and the second quick-change disk 133 is connected to the other side of the second base plate 132, and the pressing robot 110 includes a third quick-change disk 113, and the third quick-change disk 113 can be detachably mounted on the first quick-change disk 123 or the second quick-change disk 133. It can be understood that the third quick-change disk 113 can be connected to the first quick-change disk 123 or the second quick-change disk 133 according to needs, that is, the end effector of the pressing robot 110 can be quickly replaced. In addition to the pressing part, the end effector can also be compatible with other tools, such as welding guns, spray guns, suction cups, clamps, etc. (the pressing device 100 can also include the above-mentioned tools). Through this cooperation, it can be quickly connected or disassembled between different work tasks without the need for manual long-term complex tool disassembly and installation operations on the robot.

[0031] Reference Figure 2-Figure 7 In some embodiments, the first bottom plate 122 or the second bottom plate 132 may have a through hole, which may be used to avoid the structure of the limiting portion, or to reduce weight and manufacturing costs.

[0032] For the specific structure and matching form of the first quick-change disk 123, the second quick-change disk 133 and the third quick-change disk 113. In some embodiments, the structure between the first quick-change disk 123 and the second quick-change disk 133 and the connection form between each and the third quick-change disk 113 can be the same or different. The same embodiment is used as an illustration below, and the matching of the first quick-change disk 123 and the third quick-change disk 113 is used as an illustration. The first quick-change disk 123 and the third quick-change disk 113 can have mutually matching interfaces and connecting parts. Specifically, in some embodiments, the connection structure between the first quick-change disk 123 and the third quick-change disk 113 can be one of a bayonet structure, a pin structure, a magnetic structure, a threaded structure, and a spring structure. In some embodiments, an airflow channel can be formed after the first quick-change disk 123 and the third quick-change disk 113 are docked, and an adsorption force for adsorbing the first quick-change disk 123 and the third quick-change disk 113 can be generated after the airflow is passed into the airflow channel.

[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 portion 120 further includes a first detection member 124. The first pressing structure 121 is suitable for pressing a first detection hole 1211 on one side of the first limiting portion 222. The cross section of the first detection hole 1211 may be in any suitable shape. The first detection member 124 is disposed in the first detection hole 1211 so that the first detection member 124 can detect the position of the first limiting portion 222. It is understandable that after the first detection member 124 is disposed in the first detection hole 1211, the first detection member 124 can pass through the first detection hole 1211 toward the first limiting portion 222, and then detect whether the first limiting portion 222 is pressed to the target position by the first pressing portion 120. The detection method may be any suitable detection method such as laser, infrared sensor, visual sensor, etc. Arranging the first detection member 124 in the structure of the first pressing portion 120 itself is conducive to improving the detection accuracy. The above configuration is for the pressing action of the first pressing portion 120. Similarly, for the pressing action of the second pressing portion 130, refer to Figure 7 In some embodiments, the second pressing portion 130 further includes a second detecting member 134. The second pressing structure 131 is suitable for pressing a side of the second position-limiting portion 223 and has a second detecting hole 1311. The second detecting member 134 is disposed in the second detecting hole 1311 so that the second detecting member 134 can detect the position of the second position-limiting portion 223. It can be understood that the configuration of the second detecting member 134 is similar to that of the first detecting member 124, except that the objects to be detected are different. Therefore, the configuration of the second detecting member 134 can refer to the configuration of the first detecting member 124, and has the same effect as the configuration of the first detecting member 124.

[0034] Reference Figure 8-Figure 13 The second aspect of the present invention also provides a tray system, including the pressing device 100 of any of the above embodiments and a tray assembly 20. The function and related configuration of the tray assembly 20 can refer to the related descriptions of the above embodiments, which will not be repeated here.

[0035] Reference Figure 8-Figure 13 The base 210 is used to carry the electric energy meter. Specifically, one side of the base 210 has a carrying surface 211 for carrying the electric energy meter. 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, 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 through the bearing surface 211. In other words, the limiting groove 212 can be recessed in the bearing surface 211.

[0036] Reference Figure 8-Figure 9, the limiting component 220 is used to limit the electric energy meter. 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, refer to Figure 1 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 stations, for example, the tray assembly 20 may 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 method for controlling a tray, and the tray system of any of the above embodiments is applied. At the same time, the first pressing portion 120 also includes a first detecting member 124, and the second pressing portion 130 also includes a second detecting member 134. The first detecting member 124 and the second detecting member 134 are used to detect the positions of the first limiting portion 222 and the second limiting portion 223, respectively. For the arrangement of the first detecting member 124 and the second detecting member 134, reference can be made to the relevant descriptions of the above embodiments, and no further description will be given here. Fig.14 The tray control method includes but is not limited to the following steps: S101: Control the pressing device 100 to connect to the first pressing part 120 or the second pressing part 130; S102: If the pressing device 100 is connected to the first pressing portion 120, the pressing device 100 is controlled to move above the tray assembly 20, and the first pressing portion 120 is driven to press the first limiting portion 222, and the first detecting member 124 detects whether the first limiting portion 222 is pressed to the target position; If the pressing device 100 is connected to the second pressing portion 130 , the pressing device 100 is controlled to move above the tray assembly 20 , and the second pressing portion 130 is driven to press the second limiting portion 223 . The second detecting member 134 detects whether the second limiting portion 223 is pressed to the target position.

[0046] The above steps are further described below. In step S101, the selection and judgment of connecting the first pressing part 120 or the second pressing part 130 can be determined according to 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. The pressing device 100 can automatically move and grab the first pressing part 120 or the second pressing part 130 through programming or visual detection device, or the operator can control the pressing device 100 to grab 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 mode of the pressing device 100, the driving pressing mode and the detection mode can all refer to the relevant descriptions of the above embodiments. In addition, if the detection is unqualified, the pressing device 100 can issue an alarm, or automatically perform an additional pressing operation on one side. If the detection is qualified, the pressing operation is completed. After completing one pressing operation, the pressing robot 110 can remain in place or rotate and switch its connected pressing parts according to subsequent pressing requirements to prepare for the next pressing operation.

[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.
