[0029] For the assembly of the battery, generally, the battery cells are manually placed into the housing, and the installation position of the battery is visually observed for accuracy. Manual operation inevitably has errors, there is a risk of incomplete installation, and the assembly efficiency is also low. Moreover, when manually operating the battery cells and the housing, it is easy to collide with other components or tooling, resulting in the risk of poor appearance.

[0030] Therefore, the applicant provides an assembly mechanism.

[0031] Referring to Figure 1 , Figure 4 and Figure 5 According to some embodiments of the present invention, the present invention provides an assembly mechanism 100. The assembly mechanism 100 includes a frame 10, an operating table 20, a material taking device 30, a transfer tooling 40, and an installation tooling 50. The operating table 20 is arranged on the frame 10. The material taking device 30 is provided with a positioning member 31 and a suction member 32. The transfer tooling 40 is arranged on the operating table 20. The transfer tooling 40 is provided with a first positioning portion 41 and a second positioning portion 42. The first positioning portion 41 is used for positioning the first workpiece, and the second positioning portion 42 is used for cooperating with the positioning member 31 for positioning. The installation tooling 50 is arranged on the operating table 20. The installation tooling 50 is provided with a third positioning portion 51 and a fourth positioning portion 52. The third positioning portion 51 is used for positioning the second workpiece, and the fourth positioning portion 52 is used for cooperating with the positioning member 31 for positioning. The suction member 32 is used for obtaining the first workpiece from the transfer tooling 40 and placing it on the second workpiece of the installation tooling 50.

[0032] The assembling mechanism 100 places or installs the first workpiece onto the second workpiece. Here, the second workpiece can be the outer shell of a battery, and the first workpiece can be the battery cell. The frame 10 can be a framework placed on the ground, which can be made of aluminum alloy rods or PVC pipes. The operating table 20 is a support table suitable for placing tools and devices. The installation tooling 50 is used to place the outer shell of the battery. Specifically, a third positioning portion 51 is provided on the installation tooling 50. The third positioning portion 51 can cooperate with the structure on the outer shell for clamping or positioning, and is used for installing and positioning the outer shell of the battery. A first positioning portion 41 is provided on the transfer tooling 40. The first positioning portion 41 can cooperate with the structure on the battery cell for clamping or positioning, and is used for installing and positioning the battery cell. Specifically, a battery cell positioning rod or a battery cell positioning pin can be provided to cooperate with the battery cell for installing and positioning it. In actual production, the battery cell can be manually placed on the transfer tooling 40 to cooperate with the first positioning portion 41 first, and the outer shell can be placed on the installation tooling 50 to cooperate with the third positioning portion 51, thus completing the preliminary positioning. Of course, the battery cell can also be positioned on the transfer tooling 40 by a manipulator, and the outer shell can be positioned on the installation tooling 50 by a manipulator to achieve fully automated operation. After the installation is completed, the suction attachment 32 of the material taking device 30 can be controlled to pick up the first workpiece from the transfer tooling 40 and place it on the second workpiece on the installation tooling 50. To improve the installation accuracy, the applicant sets the material taking device 30 to include a positioning member 31, and a second positioning portion 42 is provided on the transfer tooling 40. When the material taking device 30 moves to the transfer tooling 40 and is ready to pick up the material, the material taking device 30 will move downward. At this time, the positioning member 31 first cooperates with the second positioning portion 42. After the cooperation is completed, the material taking device 30 can continue to move downward a certain distance or not move to adsorb the first workpiece. When the interval between the suction attachment 32 and the first workpiece reaches a preset position, the suction attachment 32 is opened to adsorb and pick up the first workpiece. In this way, by first positioning and cooperating the second positioning portion 42 with the positioning member 31 and then picking up the first workpiece, the picking position of the first workpiece can be controlled, or in other words, the position of the first workpiece on the suction attachment 32 can be controlled, which is convenient for controlling the installation accuracy of the subsequent installation onto the second workpiece. At the same time, the applicant also sets a fourth positioning portion 52 on the installation tooling 50. When the material taking device 30 moves above the installation tooling 50 and moves downward towards the installation tooling 50, the positioning member 31 will first cooperate with the fourth positioning portion 52. Only when the positioning member 31 cooperates accurately with the fourth positioning portion 52 can the material taking device 30 continue to move downward. At this time, the first workpiece and the second workpiece continue to approach, the suction attachment 32 disconnects to release the first workpiece, and the first workpiece is placed on the second workpiece.After the fourth positioning part 52 and the positioning piece 31 are accurately matched and then the first workpiece is placed down, the falling position of the first workpiece can be accurately controlled. And in cooperation with the primary positioning of the first positioning part 41 for the placing position of the first workpiece and the positioning of the third positioning part 51 for the second workpiece, it is beneficial to improve the installation accuracy of the workpiece. Moreover, automated installation is adopted, which can improve the installation efficiency. In addition, during the installation process, the adsorbing part 32 is used to pick up and place, reducing the risk of scratching the battery shell by manual operation and causing poor appearance. This embodiment has the advantages of high installation accuracy, high production efficiency, and the ability to reduce poor appearance. In some specific embodiments, a tray 60 is further provided on the operating table 20. The tray 60 is used to store the first workpiece or the second workpiece, and can store multiple workpieces at a time.

[0033] Referring to Figure 2 and Figure 3 , in some embodiments, the material taking device 30 includes a bracket 33, a first rotation driving part 34, a lifting part 35, a connecting arm 36 and a grasping component 303. The first rotation driving part 34 is installed on the bracket 33. The lifting part 35 is connected to the output shaft 341 of the first rotation driving part 34. The connecting arm 36 is connected to the lifting part 35. The grasping component 303 includes a base 37, an adsorbing part 32 and a positioning piece 31 respectively installed on the base 37. The base 37 is connected to the connecting arm 36.

[0034] The bracket 33 may include a horizontal plate 331 and a vertical plate 332 connected to each other, specifically, they may be perpendicular to each other. The horizontal plate 331 is installed on the operating table 20, and the vertical plate 332 is fixedly installed on the frame 10. Since other components of the entire material taking device 30 rely on the bracket 33 for support, setting the vertical plate 332 to be installed on the frame 10 can play a role in force balance and prevent the material taking device 30 from tipping over. The first rotation driving part 34 includes a cylinder body and an output shaft 341 rotatably installed in the cylinder body. The output shaft 341, like the vertical plate 332, can be arranged in the vertical direction. The lifting part 35 is installed on the output shaft 341 and can move up and down along the output shaft 341. The connecting arm 36 is installed on the lifting part 35. Thus, the connecting arm 36 can be controlled to perform rotational and lifting movements to adjust the position of the grasping component 303, and further adjust the positions of the adsorbing part 32 and the positioning piece 31. Specifically, the grasping component 303 includes a base 37, an adsorbing part 32 and a positioning piece 31, and the base 37 plays a role of connection and installation. The connecting arm 36 may be a horizontal vertical arm. Compared with the traditional components using a six-axis robot and three-dimensional drive, this embodiment has a low cost and can reduce the manufacturing cost of the assembled structure.

[0035] Referring to Figure 2In some embodiments, the lifting member 35 includes a hinge plate 351 and a sliding seat 352, the connecting arm 36 is installed on the sliding seat 352, the sliding seat 352 is slidably installed on the output shaft 341, the hinge plate 351 includes a plate body and a hinge, the plate body is suspended on the top of the bracket 33, and one end of the hinge extends from the plate body and is connected to the sliding seat 352.

[0036] The hinge plate 351 is similar to a gravity-balanced hinge, including a plate body and a hinge wound around the outer periphery of the plate body. A driving motor can also be provided to be connected to the plate body in a transmission manner to control the extension length of the hinge to control the position of the sliding seat 352. Specifically, the sliding seat 352 can slide on the output shaft 341. The plate body is arranged on the top of the bracket 33 and is also arranged above the sliding seat 352. One end of the hinge is connected to the sliding seat 352 to provide a vertical upward pulling force to the sliding seat 352. In this way, the pulling force of the hinge can provide a vertical upward pulling force to the sliding seat 352. This pulling force can balance the gravity of the sliding seat 352, and can also offset or balance the gravity of the hanging connecting arm 36 and the grabbing assembly 303, so that the influence of gravity on the grabbing assembly 303 during movement is reduced, which is conducive to improving the convenience and accuracy of movement. At the same time, the length of the released hinge can be controlled by the rotation of the plate body, so as to achieve the effect of controlling the height of the sliding seat 352 and then controlling the height of the grabbing assembly 303.

[0037] Reference Figure 2 In some embodiments, the lifting member 35 also includes a guide rod 39, which is arranged parallel to the output shaft 341 and extends in the vertical direction. The sliding seat 352 includes a first seat body and a second seat body connected to each other. The first seat body is slidably installed on the output shaft 341, and the second seat body is slidably installed on the guide rod 39. The connecting arm 36 is installed on the first seat body or the second seat body.

[0038] The guide rod 39, like the output shaft 341, is arranged in parallel and extends in the vertical direction. In this example, the sliding seat 352 includes two parts, namely the first seat body and the second seat body. The first seat body is slidably mounted on the output shaft 341, and the second seat body is slidably mounted on the guide rod 39. The first seat body and the second seat body are connected to each other and move synchronously. Of course, in order to prevent the sliding seat 352 from moving beyond the limit, a limit block 302 is provided near the first rotary drive member 34. The first limit block 302 can be fixedly sleeved on the output shaft 341 and the guide rod 39. When the sliding seat 352 moves to a certain position, it will abut against the limit block 302 and cannot continue to move downward. The setting of the guide rod 39 can play a role in controlling the moving direction of the sliding seat 352, ensuring that the adjustment direction is along the vertical direction. At the same time, it can share a part of the torque for the output shaft 341, playing a protective role and reducing the risk of the output shaft 341 breaking. At the same time, the setting of the limit block 302 can prevent the sliding seat 352 from moving beyond the preset limit, and can also play a protective role.

[0039] Referring to Figure 3 , in some embodiments, the suction attachment 32 includes a vacuum generator, a suction cup 321, and a switch 322. The suction cup 321 is mounted on the base 37. The vacuum generator is communicated with the suction cup 321, and the vacuum generator is signal-connected to the switch 322.

[0040] The suction attachment 32 can adopt the form of vacuum adsorption. The vacuum generator is communicated with the suction cup 321 and is used to extract the air in the suction cup 321 to generate negative pressure to suck the first workpiece, or to introduce air into the suction cup 321 to put down the first workpiece. The side of the vacuum suction cup 321 that adsorbs the first workpiece can be made of rubber material. The vacuum adsorption method can better protect the appearance of the first workpiece and reduce the influence of appearance defects. For easy control, a switch 322 can also be provided and signal-connected to the vacuum generator to control the opening and closing of the vacuum generator.

[0041] Referring to Figure 3 , in some embodiments, the grasping assembly 303 further includes an elastic member and a slide rod 301. The suction cup 321 includes a base 323 and an adsorption part. The base 323 is slidably mounted on the slide rod 301. The two ends of the elastic member are respectively abutted against the base 37 and the base 323.

[0042] The sliding rod 301 is generally arranged vertically. There can be multiple sliding rods 301, and the multiple sliding rods 301 are arranged in parallel. The base 323 can move up and down along the sliding. The elastic member can be a spring. The base 37 can include an abutting plate 371. The base 323 and the abutting plate 371 are arranged in parallel. The sliding rod 301 sequentially passes through the abutting plate 371 and the base 323. The two ends of the spring are respectively abutted against the abutting plate 371 and the base 323, and the abutting plate 371 is immovable. After the positioning member 31 is engaged with the first positioning portion 41, when the grasping assembly 303 continues to move downward, the suction portion may touch the first workpiece. At this time, there will be an impact force. In order to reduce the possible damage to the first workpiece, an elastic member is provided to play a buffering role. At this time, the elastic member will contract so that the suction portion moves upward, reducing the contact force with the first workpiece.

[0043] Referring Figure 3 and Figure 4 , in some embodiments, the positioning member 31 includes a positioning pin 311. The positioning pin 311 extends a certain distance out of the suction cup 321. The second positioning portion 42 includes a first positioning hole 421, and the fourth positioning portion 52 includes a second positioning hole 521. After the positioning pin 311 is inserted and engaged with the first positioning hole 421 for positioning, the suction cup 321 adsorbs the first workpiece, and after the first positioning pin 311 is engaged with the second positioning hole 521 for positioning, the suction cup 321 releases the first workpiece.

[0044] The positioning pin 311 is a protruding rod-shaped object. The setting position of the positioning pin 311 is lower than that of the suction cup 321, or rather, the end of the positioning pin 311 is arranged at a lower position of the suction cup 321. This is mainly to ensure that the positioning pin 311 can be engaged with the first positioning hole 421 first during the downward movement of the material taking device 30. The engagement of the positioning pin 311 with the first positioning hole 421 indicates accurate positioning before sucking the first workpiece, so that the position of the first workpiece on the suction member 32 can be accurately positioned. In addition, the second positioning portion 42 is provided with a first positioning hole 421. After the positioning pin 311 is aligned with the first positioning hole 421 and continues to move downward a short distance, the suction member 32 will be opened to adsorb the first workpiece. A first pressure sensor can be provided at the end of the positioning pin 311 or at the bottom of the first positioning hole 421. During the process of the positioning pin 311 continuing to extend into the first positioning hole 421, the contact pressure between the two will gradually increase. When the value of the first pressure sensor increases to a certain preset value, it indicates that the positioning pin 311 has reached the preset position, and it also indicates that the distance between the suction cup 321 and the first workpiece has reached the preset target. The downward movement can be stopped, and the vacuum generator can be turned on to adsorb the first workpiece. By setting the first pressure sensor, the distance between the suction cup 321 and the first workpiece can be controlled, which can not only reduce the risk of unstable adsorption due to too large a distance between the suction cup 321 and the first workpiece, but also reduce the risk of damaging the first workpiece due to excessive movement of the suction cup 321.

[0045] Similarly, after the first workpiece is adsorbed, the grasping component 303 moves towards the installation tooling 50. When it moves above the installation tooling 50, it starts to move downward towards the second workpiece. During the downward movement, the positioning pin 311 can first cooperate with the second positioning hole 521. The cooperation between the positioning pin 311 and the second positioning hole 521 indicates accurate positioning before the first workpiece is released. In this way, the installation position where the first workpiece falls onto the second workpiece can be accurately positioned. After the positioning pin 311 is aligned with the second positioning hole 521, it continues to move downward a short distance before the suction attachment 32 is closed to release the first workpiece. Similarly, a second pressure sensor can also be provided at the bottom of the second positioning hole 521 or at the end of the positioning pin 311. Its function is similar to the description in the previous paragraph, which is used to strictly control the distance between the first workpiece and the second workpiece, avoiding damaging the second workpiece due to excessive distance or causing mutual damage between the first workpiece and the second workpiece due to too small a distance.

[0046] In addition, it should be noted that the number of positioning pins 311 can be two or more. When the number of positioning pins 311 is two, the number of the first positioning holes 421 and the second positioning holes 521 is also two. The two positioning pins 311 can be respectively arranged at two diagonals of the suction cup 321 to reduce the risk of tilting on one side.

[0047] Refer to Figure 3 , in some embodiments, the grasping component 303 further includes a second rotation driving member 38. The base 37 includes a connecting seat and a mounting seat. The connecting arm 36 is connected to the connecting seat. The second rotation driving member 38 is installed on the connecting seat and is connected to the mounting seat. The suction attachment 32 and the positioning member 31 are arranged on the mounting seat.

[0048] The second rotation driving member 38 can include a rotation motor, which is used to drive the mounting seat connected to it to rotate, and further make the suction attachment 32 and the positioning member 31 rotate. The first rotation driving member 34 is used to control the rotation of the suction attachment 32 and the positioning member 31 in a larger space, and the second rotation driving member 38 is used to control the fine adjustment of the suction attachment 32 and the positioning member 31 within a smaller range. The cooperation of the two takes into account the requirements of both efficiency and accuracy.

[0049] Refer to Figure 5 and Figure 6 , in some embodiments, the installation tooling 50 includes an upper tooling 53 and a lower tooling 54. The lower tooling 54 includes a substrate 541, a profiling hole 542 arranged on the substrate 541, and a preloading member 543 hinged to the substrate 541. The profiling hole 542 is used to install the second workpiece and position the second workpiece. The preloading member 543 is used to press the second workpiece. The upper tooling 53 includes a lifting driving member 531 and a pressing arm 532. The lifting driving member 531 is used to drive the pressing arm 532 to move towards the lower tooling 54 to press the second workpiece tightly.

[0050] The third positioning part 51 can be a profiling hole 542. The installation tooling 50 is used to position and fix the second workpiece. When the second workpiece is the outer shell of a battery, the protruding structure of the outer shell can be placed into the profiling hole 542 to achieve the positioning of the outer shell. The pre-pressing part 543 can be a tongue-shaped pre-pressing plate. The pre-pressing plate is hinged to the substrate 541 and can rotate around the substrate 541. The pre-pressing plate is arranged close to the profiling hole 542. When installing the outer shell, the upper tooling 53 can be lifted first. At the same time, the pre-pressing plate is rotated to open the pre-pressing plate. The protruding structure of the outer shell is placed into the profiling hole 542, and then the pre-pressing plate is lowered and pressed on the outer shell, which can give the outer shell a pressing force towards the substrate 541. Of course, a torsion spring can also be set so that the pre-pressing plate can automatically return to its position to press the outer shell tightly. The upper tooling 53 includes a lifting driving part 531 and a pressing arm 532. The pressing arm 532 can be a frame-like structure with a hollow middle. The lifting driving part 531 is used to drive the movement along the vertical direction. When the outer shell is installed on the lower tooling 54, the pressing arm 532 can be driven by the lifting driving part 531 to move towards the outer shell, and the outer shell is further pressed tightly through the pressing arm 532. Specifically, the number of the pre-pressing parts 543 can be multiple, and the outer shell is pressed tightly from multiple positions. The lower tooling 54 can also include a handle installed on the substrate 541, which is convenient for taking and moving the lower tooling 54.

[0051] Referring to Figure 5 , in some embodiments, the lifting driving part 531 includes a handle 5311, a mounting plate 5312, a moving plate 5313 and a support rod 5314. The handle 5311 is arranged on the mounting plate 5312 and connected to the moving plate 5313. The moving plate 5313 is slidably mounted on the support rod 5314, and the pressing arm 532 is mounted on the moving plate 5313.

[0052] The mounting plate 5312 is provided with a through hole for a part of the structure of the handle 5311 to pass through, so that the handle 5311 can be mounted on the mounting plate 5312 and connected to the moving plate 5313. The moving plate 5313 and the mounting plate 5312 are arranged at intervals and in parallel. By pressing the handle 5311, the moving plate 5313 can be pulled to move. The support rod 5314 provides guiding and limiting functions for the movement of the moving plate 5313, so that the moving plate 5313 moves along the vertical direction. The pressing arm 532 is mounted on the moving plate 5313. In this way, the pressing arm 532 can be controlled to move along the vertical direction through the handle 5311 to press the outer shell tightly or loosen it.

[0053] Referring to Figure 5 , in some embodiments, the pressing arm 532 is provided with a pre-pressing roller 533, and the pre-pressing roller 533 is used for rolling connection with the second workpiece.

[0054] The preloading roller 533 can be in contact with the second workpiece to press the second workpiece, or can be in contact with the preloading member 543 to press the preloading member 543. The form of setting the roller can reduce the frictional force between the two through the form of rolling friction.

[0055] In some embodiments, the picking device 30 further includes an image recognition device and a controller. The image recognition device is configured to obtain the image information of the second positioning portion 42 and the fourth positioning portion 52, and send the image information to the controller. The controller obtains the position information of the second positioning portion 42 and the fourth positioning portion 52 according to the image information, and generates a control instruction to control the positioning member 31 to cooperate with the second positioning portion 42 or the fourth positioning portion 52 for positioning.

[0056] When picking the first workpiece, the image recognition device can obtain the image information of the second positioning portion 42 and the transfer tooling 40, and transmit the image information to the controller. The controller can obtain the position information of the second positioning portion 42 according to the image information, and judge whether the positioning member 31 is aligned with the second positioning portion 42 by combining the coordinate information of the positioning member 31. If not, the controller controls the positioning member 31 to move to change the coordinate position of the positioning member 31. If it is already aligned, the controller controls the positioning member 31 to move downward to engage with the second positioning portion 42. Similarly, when placing the first workpiece on the installation tooling 50, the image recognition device can obtain the image information of the fourth positioning portion 52 and the installation tooling 50, and transmit the image information to the controller. The controller can obtain the position information of the fourth positioning portion 52 according to the image information, and judge whether the positioning member 31 is aligned with the fourth positioning portion 52 by combining the coordinate information of the positioning member 31. If not, the controller controls the positioning member 31 to move to change the coordinate position of the positioning member 31. If it is already aligned, the controller controls the positioning member 31 to move downward to engage with the fourth positioning portion 52. This embodiment can realize the automatic adjustment of the position of the positioning member 31 to ensure the accurate cooperation between the positioning member 31 and the second positioning portion 42 and the fourth positioning portion 52.

[0057] Referring to Figure 7 , Figure 7 which is the flow schematic diagram of the first embodiment of the present invention. The present invention provides a battery assembly method, which is applied to the above-mentioned assembly mechanism 100. The battery assembly method includes: S100, placing the first workpiece on the first positioning portion 41 of the transfer tooling 40, and placing the second workpiece on the third positioning portion 51 of the installation tooling 50.

[0058] As described above, the first workpiece can be an electric core, the second workpiece can be a housing, the first positioning portion 41 is used for positioning the first workpiece, and the third positioning portion 51 is used for positioning the second workpiece.

[0059] S200, control the positioning member 31 to cooperate with the second positioning portion 42 of the transfer tooling 40 for positioning, and control the suction member 32 to start sucking the first workpiece.

[0060] Here, the positioning member 31 can be a positioning pin 311, and the second positioning portion 42 can include a first positioning hole 421. The positioning pin 311 refers to a protruding rod-shaped object. The setting position of the positioning pin 311 is lower than that of the suction cup 321. Or rather, the end of the positioning pin 311 is set at a position lower than that of the suction cup 321. This is mainly to ensure that the positioning pin 311 can cooperate with the first positioning hole 421 first during the downward movement of the picking device 30. The cooperation between the positioning pin 311 and the first positioning hole 421 indicates accurate positioning before sucking the first workpiece. In this way, the position of the first workpiece on the suction member 32 can be accurately positioned. In addition, the second positioning portion 42 is provided with a first positioning hole 421. After the positioning pin 311 is aligned with the first positioning hole 421 and continues to move downward a small distance, the suction member 32 will be opened to adsorb the first workpiece. Here, a first pressure sensor can be provided at the end of the positioning pin 311 or at the bottom of the first positioning hole 421. During the process of the positioning pin 311 continuing to extend into the first positioning hole 421, the contact pressure between the two will gradually increase. When the value of the first pressure sensor reaches a certain preset value, it indicates that the positioning pin 311 has reached the preset position, and it also indicates that the distance between the suction cup 321 and the first workpiece has reached the preset target. At this time, the downward movement can be stopped, and the vacuum generator can be turned on to adsorb the first workpiece. That is to say, after the step of controlling the positioning member 31 to cooperate with the second positioning portion 42 for positioning and before the step of controlling the suction member 32 to start sucking the first workpiece, the following step can also be included: receiving the pressure signal sent by the first pressure sensor, and when the pressure signal reaches the first preset value, controlling the suction member 32 to start sucking the first workpiece. By providing the first pressure sensor, the distance between the suction cup 321 and the first workpiece can be controlled, which can not only reduce the risk of unstable adsorption due to too large a distance between the suction cup 321 and the first workpiece, but also reduce the risk of damaging the first workpiece due to excessive movement of the suction cup 321.

[0061] S300, control the positioning member 31 to cooperate with the fourth positioning portion 52 of the installation tooling 50 for positioning, and control the suction member 32 to close and release the first workpiece to place the first workpiece on the second workpiece.

[0062] After adsorbing to the first workpiece, the material taking device 30 moves towards the installation tooling 50. When it moves above the installation tooling 50, it starts to move downward towards the second workpiece. During the downward movement, the positioning pin 311 can first cooperate with the second positioning hole 521. The cooperation between the positioning pin 311 and the second positioning hole 521 indicates that the positioning is accurate before the first workpiece is released. In this way, the installation position of the first workpiece on the second workpiece can be accurately positioned. After the positioning pin 311 is aligned with the second positioning hole 521, it continues to move downward a small distance before the adsorbing member 32 is closed to release the first workpiece. Similarly, a second pressure sensor can be arranged at the bottom of the second positioning hole 521, or a second pressure sensor can be arranged at the end of the positioning pin 311. That is to say, between the step of controlling the cooperation and positioning of the positioning member 31 and the fourth positioning portion 52 and the step of controlling the adsorbing member 32 to close and release the first workpiece, there is also a step: receiving the pressure signal sent by the second pressure sensor, and when the pressure signal reaches the second preset value, controlling the adsorbing member 32 to close the first workpiece. The function of setting the second pressure sensor is similar to the description in the previous paragraph, which is used to strictly control the distance between the first workpiece and the second workpiece, to avoid damaging the second workpiece due to too large a distance or causing mutual damage between the first workpiece and the second workpiece due to too small a distance.
