In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0024] The sensor element protection cover assembly machine of the present application is used to assemble the first protection cover 810 and the second protection cover 820 to the back plate 830 to protect the sensor element on the back plate 830. It should be understood that in some embodiments, the first protection cover 810 and the second protection cover 820 have different shapes, and in other embodiments, the first protection cover 810 and the second protection cover 820 are the same.

[0025] Reference Figure 1 and Figure 2The sensor element protection cover assembly machine of the present application includes: an assembly device 100, a pressing device 200 and a fastening device 300.

[0026] Reference Figure 3 The assembly device 100 is used to install the first protective cover 810 and the second protective cover 820 to the back plate 830 respectively. Figure 6 and Figure 7 The pressing device 200 includes a pressing part 210 and a pressing driving part 220. The pressing driving part 220 drives the pressing part 210 to drive the pressing part 210 to abut against the side of the first protective cover 810 installed on the back plate 830 away from the back plate 830. The fastening device 300 is used to pass the fastener through the first protective cover 810 and the back plate 830 abutting against the pressing part 210 when the second protective cover 820 is installed on the assembling device 100.

[0027] In one specific mode of operation, reference Figure 3 The assembly device 100 first grabs the first protective cover 810 and the second protective cover 820, and then installs the first protective cover 810 to the back plate 830, for example, placing the first protective cover 810 on the back plate 830 or snapping the first protective cover 810 and the back plate 830. Figure 6 and Figure 7 Then, the material pressing driving part 220 drives the material pressing part 210 to abut against the side of the first protective cover 810 away from the back plate 830, so as to press the first protective cover 810 onto the back plate 830, thereby fixing the first protective cover 810 relative to the back plate 830. After the material pressing part 210 abuts against the first protective cover 810, the assembly device 100 moves away from the first protective cover 810 on the back plate 830 and approaches the installation position of the second protective cover 820 on the back plate 830. The assembly device 100 installs the second protective cover 820 onto the back plate 830, for example, placing the second protective cover 820 on the back plate 830 or clamping the second protective cover 820 with the back plate 830. At the same time, the fastening device 300 passes the fasteners it grabs through the first protective cover 810 and the back plate 830 to assemble the first protective cover 810 to the back plate 830.

[0028] Therefore, it should be understood that, in the process of the assembly device 100 installing the second protective cover 820 to the back plate 830, the pressing part 210 keeps pressing on the first protective cover 810, so that, in the process of the fastening device 300 installing the fastener, the first protective cover 810 can be fixed relative to the back plate 830 to avoid the first protective cover 810 from shifting or rotating relative to the back plate 830, so as to ensure the assembly quality. In addition, due to the fixing effect of the pressing part 210 on the first protective cover 810, the assembly device 100 does not need to cooperate with the fastening device 300 to work, and the assembly device 100 does not need to press the first protective cover 810 during the process of the fastening device 300 installing the fastener, so that the installation process of the second protective cover 820 and the installation process of the fastener on the first protective cover 810 can be carried out simultaneously to improve production efficiency.

[0029] In other operation modes, the assembling device 100 may first grab the first protective cover 810 , and after the pressing portion 210 presses the first protective cover 810 , the assembling device 100 grabs the second protective cover 820 .

[0030] It should be noted that in the prior art, the first protective cover 810 and the second protective cover 820 are assembled separately using two devices. Therefore, compared with the prior art, the sensor element protective cover assembly machine of the present application can simultaneously complete the installation of the first protective cover 810 and the second protective cover 820 through the assembly device 100, the pressing device 200 and the fastening device 300, so as to reduce the occupied space of the equipment and save the production cost of the equipment.

[0031] In a specific application scenario, the fastener is a screw, and the fastening device 300 is a screw locking robot. The fastening device 300 needs to screw the screw to the first protective cover 810 and the back plate 830. In the process of screwing the screw by the fastening device 300, it is easy to drive the first protective cover 810 to rotate relative to the back plate 830. Therefore, under the limiting action of the pressing part 210 and the pressing drive part 220, the first protective cover 810 can be limited to rotate relative to the back plate 830, thereby ensuring the installation accuracy of the first protective cover 810. Of course, in some other application scenarios, the fastener can also be a pin or a rivet, etc., and the fastening device 300 is a robot that assembles the corresponding fasteners. Specifically, in order to facilitate the fastening device 300 to obtain fasteners, the sensor element protective cover assembly machine of the present application also includes a fastener feeder.

[0032] It should be understood that, in order to ensure the position accuracy of the first protective cover 810 relative to the back plate 830, before the pressing part 210 abuts against the first protective cover 810, the assembly device 100 keeps grasping the first protective cover 810 so that the first protective cover 810 remains pressed against the back plate 830 to prevent the first protective cover 810 from shifting when the assembly device 100 is moved away. After the pressing part 210 abuts against the first protective cover 810, the assembly device 100 will move away from the first protective cover 810 and then install the second protective cover 820.

[0033] Regarding the specific form of the assembly device 100: In this embodiment, refer to Figure 3 , Figure 4 and Figure 5 The assembly device 100 includes a driving module 110 and at least two installation modules 120. The driving module 110 drives and connects multiple installation modules 120 to drive the installation modules 120 to move relative to the back plate 830; at least one installation module 120 is used to install the first protective cover 810 to the back plate 830, and at least one installation module 120 is used to install the second protective cover 820 to the back plate 830.

[0034] It is understandable that the driving module 110 drives multiple installation modules 120 simultaneously, so that at least two installation modules 120 respectively grab the first protective cover 810 and the second protective cover 820, and at least two installation modules 120 respectively install the first protective cover 810 and the second protective cover 820 to the back plate 830.

[0035] For example, refer to Figure 3 , Figure 4 and Figure 5There are two mounting modules 120, one of which is used to grab the first protective cover 810 from the loading position of the first protective cover 810 and install the first protective cover 810 to the back plate 830, and the other mounting module 120 is used to grab the second protective cover 820 from the loading position of the second protective cover 820 and install the second protective cover 820 to the back plate 830. For the convenience of description, the mounting module 120 for mounting the first protective cover 810 is defined as the first mounting module 120a, and the mounting module 120 for mounting the second protective cover 820 is defined as the second mounting module 120b. The driving module 110 drives the first installation module 120a and the second installation module 120b to move to the loading position of the first protective cover 810 and the loading position of the second protective cover 820 respectively, so that the first installation module 120a and the second installation module 120b can grab the first protective cover 810 and the second protective cover 820 respectively; the driving module 110 can also drive the first installation module 120a and the second installation module 120b to move relative to the back plate 830 respectively, so that the first installation module 120a installs the first protective cover 810 to the corresponding position on the back plate 830, and the second installation module 120b installs the second protective cover 820 to the corresponding position on the back plate 830. Thus, the first installation module 120a and the second installation module 120b are driven simultaneously by one driving module 110, so that the use of the driving module 110 can be saved, the production cost can be saved, and the occupied space of the equipment can be reduced.

[0036] It should be noted that the first installation module 120a and the second installation module 120b may also include multiple ones, so as to simultaneously grasp multiple first protective covers 810 and second protective covers 820 to improve production efficiency.

[0037] In other embodiments, the assembly device 100 may also include only an installation module 120 and a driving module 110. The driving module 110 first drives the installation module 120 to grab the first protective cover 810. After the installation module 120 completes the installation of the first protective cover 810 and the pressing part 210 presses the first protective cover 810, the driving module 110 drives the installation module 120 to grab the second protective cover 820, and allows the installation module 120 to complete the installation of the second protective cover 820.

[0038] In order to avoid interference between the material picking process or installation process of multiple installation modules 120, refer to Figure 3 The installation module 120 includes a material taking head 130 , and at least one installation module 120 further includes a lifting drive unit 140 b , and the lifting drive unit 140 b drives the material taking head 130 connected to the corresponding installation module 120 .

[0039] It is understandable that at least one installation module 120 includes a lifting drive unit 140b and a material taking head 130, and the lifting drive unit 140b can drive the corresponding material taking head 130 to rise and fall. Therefore, the material taking head 130 connected to the lifting drive unit 140b can rise and fall relative to the material taking heads 130 in other installation modules 120, so that the material taking heads 130 are staggered in the height direction, so that the material taking heads 130 can take materials or install the first protective cover 810 / the second protective cover 820, and avoid the material taking process or installation process of the material taking head 130 being interfered by other material taking heads 130.

[0040] For example, for ease of presentation, refer to Figure 4 The material taking head 130 of the first installation module 120a is defined as the first material taking head 130a, referring to Figure 5 , the material taking head 130 of the second installation module 120b is defined as the second material taking head 130b. Figure 5 The second installation module 120b also includes a lifting drive unit 140b that drives and connects to the second material taking head 130b. The lifting drive unit 140b can drive the second material taking head 130b to rise and fall. When the first material taking head 130a takes materials or installs the first protective cover 810, the lifting drive unit 140b drives the second material taking head 130b to rise to a position higher than the first material taking head 130a, so that the first material taking head 130a is lower than the second material taking head 130b, so that the first material taking head 130a can take materials or install the first protective cover 810. When the second material taking head 130b takes materials or installs the second protective cover 820, the lifting drive unit 140b drives the second material taking head 130b to descend to a position lower than the first material taking head 130a, so that the second material taking head 130b can take materials or install the second protective cover 820.

[0041] It should be noted that in some other embodiments, only the first installation module 120a may include the lifting drive unit 140b, while the second installation module 120b does not include the lifting drive unit 140b, or both the first installation module 120a and the second installation module 120b may include the lifting drive unit 140b.

[0042] Specifically, the material picking method of the material picking head 130 includes clamping, vacuum adsorption or magnetic adsorption, etc., which is not limited here.

[0043] In order to improve the installation accuracy of the first protective cover 810 / the second protective cover 820, refer to Figure 3 At least one installation module 120 further includes a rotation driving unit 150, and the rotation driving unit 150 drives the material taking head 130 connected to the corresponding installation module 120 to drive the material taking head 130 to rotate.

[0044] It can be understood that the rotating drive unit 150 can drive the material picking head 130 to rotate so as to adjust the horizontal orientation of the first protective cover 810 / second protective cover 820 grasped by the material picking head 130, thereby ensuring the accurate posture of the first protective cover 810 / second protective cover 820 relative to the back plate 830, so as to improve the installation accuracy of the first protective cover 810 / second protective cover 820 relative to the back plate 830.

[0045] For example, refer to Figure 4 and Figure 5 , the first installation module 120a and the second installation module 120b both include a rotation drive unit 150. For ease of description, the rotation drive unit 150 of the first installation module 120a is defined as the first rotation drive unit 150a, and the rotation drive unit 150 of the second installation module 120b is defined as the second rotation drive unit 150b. The first rotation drive unit 150a is drivingly connected to the first material picking head 130a to drive the first material picking head 130a to rotate, and the second rotation drive unit 150b is drivingly connected to the second material picking head 130b to drive the second material picking head 130b to rotate. Specifically, when the second installation module 120b includes a lifting drive unit 140b, the driving end of the second rotation drive unit 150b is connected to the lifting drive unit 140b, and the driving end of the lifting drive unit 140b is drivingly connected to the second material picking head 130b. The second rotation drive unit 150b drives the lifting drive unit 140b to rotate to drive the second material picking head 130b to rotate.

[0046] It should be noted that, in some other embodiments, only the first installation module 120 a or the second installation module 120 b may include the rotation driving unit 150 .

[0047] In order to facilitate the installation of the first protective cover 810 / the second protective cover 820, refer to Figure 3 and Figure 5 At least one installation module 120 further includes an angle adjustment driving unit 160b, which drives the material taking head 130 connected to the corresponding installation module 120, and is used to drive the material taking head 130 to tilt relative to the horizontal plane.

[0048] For example, in a specific application scenario, when the second installation module 120b installs the second protective cover 820 to the back panel 830, one end of the second protective cover 820 needs to be snap-connected with the back panel 830, and the snap hole on the back panel 830 corresponding to the second protective cover 820 faces the horizontal direction, so that the second protective cover 820 cannot be vertically inserted into the back panel 830 along the height direction. In order to allow one end of the second protective cover 820 to be inserted into the hole of the back plate 830, the second installation module 120b further includes an angle adjustment driving unit 160b. After the second installation module 120b reaches the top of the back plate 830, the angle adjustment driving unit 160b drives the second material taking head 130b to rotate forward by a certain angle, so that the second material taking head 130b can drive the second protective cover 820 to tilt relative to the horizontal plane, so that one end of the second protective cover 820 tilts toward the hole of the back plate 830, so that the subsequent driving module 110 drives the second material taking head 130b to insert the second protective cover 820 into the hole of the back plate 830. After one end of the second protective cover 820 is inserted into the hole, the angle adjustment driving unit 160b drives the second installation module 120b to rotate in the opposite direction by the same angle, so that the second protective cover 820 is parallel to the horizontal plane, so that the second protective cover 820 is placed flat on the back plate 830, so as to complete the installation of the second protective cover 820. It should be understood that, in order to facilitate the installation of the second protective cover 820 , the second material removal head 130 b grabs the second protective cover 820 by vacuum adsorption.

[0049] It can also be understood that, in some other application scenarios, the first protective cover 810 can also be snap-connected with the back plate 830, and the first mounting module 120a also includes an angle adjustment drive unit 160b.

[0050] It can also be understood that in some other application scenarios, the mounting surface on the back plate 830 corresponding to the first protective cover 810 / the second protective cover 820 is inclined relative to the horizontal plane, and the angle adjustment drive unit 160b drives the connected material picking head 130 so that the material picking head 130 can drive the first protective cover 810 / the second protective cover 820 it grabs to be inclined relative to the horizontal plane, so as to adjust the posture of the first protective cover 810 / the second protective cover 820 to adapt to the inclination angle of the mounting surface on the back plate 830 corresponding to the first protective cover 810 / the second protective cover 820.

[0051] It should be noted that before the pressing part 210 contacts the first protective cover 810, the material taking head 130 (i.e., the first material taking head 130a) for installing the first protective cover 810 keeps grabbing the first protective cover 810. After the pressing part 210 contacts the first protective cover 810, the first material taking head 130a will be away from the first protective cover 810. In order to avoid the first material taking head 130a interfering with the pressing process of the pressing part 210, refer to Figure 7The pressing portion 210 is provided with a through slot 211 , and the first material taking head 130 a can pass through the through slot 211 .

[0052] It can be understood that, in the process of the material pressing driving part 220 driving the material pressing part 210 to approach the first protective cover 810, the first material picking head 130a can enter the through groove 211 to avoid the material pressing part 210. After the material pressing part 210 abuts against the first protective cover 810, the first material picking head 130a can pass through the through groove 211 to stay away from the first protective cover 810, thereby ensuring that the operations of the first material picking head 130a and the material pressing part 210 do not interfere with each other.

[0053] In order to ensure the limiting effect of the first protective cover 810, the first material taking head 130a grabs the first protective cover 810 by clamping. Figure 4 The first material taking head 130a includes a clamping driving part 131a and two clamping arms 132a. The clamping driving part 131a drives and connects the two clamping arms 132a to make the clamping arms 132a approach or move away from each other to clamp or release the first protective cover 810.

[0054] Specifically, refer to Figure 6 and Figure 7The two clamping arms 132a are distributed along the first direction, and the clamping driving part 131a can drive the two clamping arms 132a to move closer to or away from each other in the first direction. The through groove 211 extends along the first direction and passes through one side of the pressing part 210, so that an opening is formed on one side of the pressing part 210. The pressing driving part 220 can drive the pressing part 210 to move horizontally along the first direction and along the height direction. Thus, after the first material taking head 130a completes the installation of the first protective cover 810, the material pressing driving unit 220 drives the material pressing unit 210 to move horizontally along the first direction, and the material pressing unit 210 approaches the first material taking head 130a, and the first material taking head 130a enters the through slot 211 from the opening, so that the first material taking head 130a and the material pressing unit 210 avoid each other, so that the material pressing unit 210 comes to the top of the first protective cover 810, and then the material pressing driving unit 220 drives the material pressing unit 210 to descend in the height direction, so that the material pressing unit 210 and the first protective cover 810 are against each other. After the material pressing unit 210 and the first protective cover 810 are against each other, the driving module 110 drives the first material taking head 130a to rise to pass through the through slot 211 and away from the first protective cover 810. It should be understood that by opening the through slot 211 to avoid the clamping arm 132a, the movement path of the material pressing unit 210 can be reduced to reduce the space occupied by the equipment. It should also be understood that the distribution direction of the two clamping arms 132a, the clamping direction of the two clamping arms 132a, the extension direction of the through slot 211 and the horizontal movement direction of the pressing portion 210 are consistent, so as to reduce the opening area of ​​the through slot 211, increase the contact area of ​​the pressing portion 210 relative to the first protective cover 810, and improve the limiting effect of the pressing portion 210 on the first protective cover 810, and in the process of the two clamping arms 132a loosening the first protective cover 810, the two clamping arms 132a move away from each other along the first direction, and the through slot 211 extending along the first direction can give the clamping arms 132a sufficient room for movement.

[0055] Specifically, the press drive unit 220 includes a vertical drive cylinder 221 and a horizontal drive cylinder 222. In some embodiments, the horizontal drive cylinder 222 is driven to connect to the vertical drive cylinder 221, and the horizontal drive cylinder 222 drives the press unit 210 to move in the first direction through the vertical drive cylinder 221, and the vertical drive cylinder 221 is driven to connect to the press unit 210 to drive the press unit 210 to move in the height direction. In other embodiments, the vertical drive cylinder 221 is driven to connect to the horizontal drive cylinder 222, and the vertical drive cylinder 221 drives the press unit 210 to move in the height direction through the horizontal drive cylinder 222, and the horizontal drive cylinder 222 is driven to connect to the press unit 210 to drive the press unit 210 to move in the first direction.

[0056] It should be noted that, in this embodiment, after the second protective cover 820 is installed on the back plate 830, it is necessary to penetrate the second protective cover 820 and the back plate 830 through the fasteners to fix the second protective cover 820 on the back plate 830. Therefore, the fastening device 300 is also used to penetrate the fasteners through the second protective cover 820 and the back plate 830. Figure 5 The material taking head 130 (ie, the second material taking head 130 b ) for installing the second protective cover 820 is provided with a through hole 131 b for passing a fastener.

[0057] It is understandable that after the second material taking head 130b installs the second protective cover 820 to the back plate 830, and the fastening device 300 passes the fastener through the first protective cover 810 and the back plate 830, the fastening device 300 passes another fastener through the second protective cover 820 and the back plate 830 to relatively fix the second protective cover 820 and the back plate 830. It should be understood that in the process of the fastening device 300 installing the fastener to the second protective cover 820, the second material taking head 130b maintains the posture of grabbing the second protective cover 820 to prevent the second protective cover 820 from shifting relative to the back plate 830, and the through hole 131b on the second material taking head 130b corresponds to the threaded hole on the second protective cover 820 that needs to be penetrated by the fastener, and the fastening device 300 drives the fastener to pass through the through hole 131b, and then pass through the second protective cover 820 and the back plate 830. It should be understood that by opening a through hole 131b for passing the fastener on the second material picking head 130b, it can play a guiding role in the process of installing the fastener by the fastening device 300, and can ensure the contact area between the second material picking head 130b and the second protective cover 820, thereby ensuring the limiting effect of the second material picking head 130b on the second protective cover 820 when installing the fastener.

[0058] Specifically, in order to improve production efficiency, the fastening device 300 can grab at least two fasteners at the same time, so that after one fastener is installed on the first protective cover 810, the other fastener can be installed on the second protective cover 820. In some other embodiments, the fastening device 300 can also grab only one fastener at a time, and grab another fastener after completing the installation of the first protective cover 810.

[0059] In order to improve the grasping accuracy of the assembly device 100 for the first protective cover 810 and the second protective cover 820, refer to Figure 1 and Figure 2The sensor element protective cover assembly machine of the present application also includes a conveying device 400, a transfer device 500 and a picking device. The conveying device 400 is used to convey the first protective cover 810 and the second protective cover 820; the picking device is used to grab the first protective cover 810 and the second protective cover 820 on the conveying device 400 to the transfer device 500; the transfer device 500 is used to pre-position the first protective cover 810 and the second protective cover 820, and the assembling device 100 is also used to grab the first protective cover 810 and the second protective cover 820 on the transfer device 500.

[0060] It is understandable that after the conveying device 400 conveys the first protective cover 810 and the second protective cover 820 to the position, the picking device can grab the first protective cover 810 and the second protective cover 820 on the conveying device 400 to the transfer device 500 separately or simultaneously, and the transfer device 500 pre-positions the first protective cover 810 and the second protective cover 820 to adjust the posture of the first protective cover 810 and the second protective cover 820. Subsequently, the assembling device 100 grabs the first protective cover 810 and the second protective cover 820 on the transfer device 500 separately or simultaneously. It should be understood that the first protective cover 810 and the second protective cover 820 are pre-positioned by the transfer device 500, and the posture of the first protective cover 810 and the posture of the second protective cover 820 are accurate when the material picking head 130 of the assembly device 100 picks up materials, ensuring that the material picking head 130 can grasp the corresponding positions of the first protective cover 810 and the second protective cover 820, and pre-adjusting the posture is conducive to the subsequent installation of the first protective cover 810 and the second protective cover 820 by the material picking head 130.

[0061] Specifically, in order to improve production efficiency, the picking device has at least two groups of picking heads, and the two groups of picking heads grab the first protective cover 810 and the second protective cover 820 respectively, so as to simultaneously transfer the first protective cover 810 and the second protective cover 820 to the transfer device 500, so as to reduce the number of round trips of the picking device between the conveying device 400 and the transfer device 500, thereby improving production efficiency. In addition, the driving module 110 drives the first material picking head 130a and the second material picking head 130b to approach the transfer device 500, so that the first material picking head 130a grabs the first protective cover 810 at the transfer device 500, and the second material picking head 130b grabs the second protective cover 820 at the transfer device 500, and then drives the first material picking head 130a and the second material picking head 130b to approach the back plate 830 together, so as to reduce the number of round trips of the material picking head 130 between the transfer device 500 and the back plate 830, thereby improving production efficiency.

[0062] Specifically, regarding the specific form of the transfer device 500, in the present embodiment, the transfer device 500 includes a plurality of accommodating chambers, the accommodating chambers are used to accommodate the first protective cover 810 or the second protective cover 820, and at least one push plate is correspondingly arranged in each accommodating chamber. The push plate can be movably arranged to shrink the accommodating chamber and push the first protective cover 810 or the second protective cover 820 in the accommodating chamber to adjust the posture of the first protective cover 810 and the second protective cover 820.

[0063] In order to improve production efficiency, the sensor element protection cover assembly machine of the present application also includes a third conveyor line 600 , which is used to convey the back plate 830 , and the pressing device 200 is arranged above the conveying path of the third conveyor line 600 .

[0064] It is understandable that the assembly device 100 can install the first protective cover 810 and the second protective cover 820 to the back plate 830 on the third conveyor line 600, the fastening device 300 can pass the fasteners through the back plate 830 on the third conveyor line 600, and the pressing device 200 can press the back plate 830 on the third conveyor line 600, so that the first protective cover 810 and the second protective cover 820 can be assembled on the third conveyor line 600 at the same time, without the need to transfer the back plate 830. After the back plate 830 is assembled, it can be transferred to the third conveyor line 600 or transported to the next production process to improve production efficiency. In addition, the equipment used to transfer the back plate 830 is reduced, the space occupied by the equipment is reduced, and the production cost is reduced.

[0065] Specifically, in order to ensure that the first protective cover 810 and the second protective cover 820 are in the correct posture, refer to Figure 2 , a detection device 700 is set between the third conveyor line 600 and the transfer device 500. After the assembly device 100 grabs the first protective cover 810 and the second protective cover 820, the first protective cover 810 and the second protective cover 820 are moved to the top of the detection device 700 to detect whether the posture of the first protective cover 810 and the second protective cover 820 is correct. If the posture is correct, the assembly device 100 installs the first protective cover 810 and the second protective cover 820 to the back plate 830. If it is not correct, the detection device 700 can feed back the signal to the rotation drive unit 150, and the rotation drive unit 150 adjusts the posture of the first protective cover 810 or the second protective cover 820 on the material picking head 130 by rotating the material picking head 130.

[0066] In order to save space on the device, refer to Figure 1 and Figure 2 The assembling device 100 , the fastening device 300 , the transfer device 500 and the picking device are all arranged between the conveying device 400 and the third conveying line 600 .

[0067] It can be understood that the conveying device 400 and the third conveyor line 600 extend along the second direction and are relatively parallel, the conveying device 400 and the third conveyor line 600 are arranged at intervals, and the assembly device 100, the fastening device 300, the transfer device 500 and the picking device are arranged between the conveying device 400 and the third conveyor line 600 so as to utilize the interval between the conveying device 400 and the third conveyor line 600 and reduce the space occupied by the equipment.

[0068] Specifically, the picking device is set up between the conveying device 400 and the transfer device 500, so that the picking device can transfer the first protective cover 810 and the second protective cover 820 at the conveying device 400 to the transfer device 500. The assembly device 100 is set up between the transfer device 500 and the third conveyor line 600, so that the assembly device 100 can transfer the first protective cover 810 and the second protective cover 820 at the transfer device 500 to the third conveyor line 600.

[0069] Specifically, in order to facilitate the pressing device 200 to press the back plate 830 on the third conveyor line 600, the pressing device 200 is set above the third conveyor line 600 to utilize the height space, thereby reducing the space occupied by the equipment. In addition, the third conveyor line 600 extends along the first direction and conveys the back plate 830 along the first direction. The pressing drive unit 220 can drive the pressing unit 210 to move horizontally along the first direction, which is consistent with the extension direction of the third conveyor line 600. Therefore, the movement trajectory of the pressing unit 210 can be prevented from exceeding the third conveyor line 600, so as to prevent the pressing unit 210 from interfering with the movement of other equipment.

[0070] Specifically, the conveying device 400 includes a first conveying line 410 and a second conveying line 420, the first conveying line 410 is used to convey the first protective cover 810, the second conveying line 420 is used to convey the second protective cover 820, the first conveying line 410 and the second conveying line 420 are distributed along a first direction, and the material-collecting end of the first conveying line 410 is opposite to the material-collecting end of the second conveying line 420. It can be understood that the first protective cover 810 and the second protective cover 820 are respectively conveyed by the first conveying line 410 and the second conveying line 420, so that the picking device can pick up the material. Furthermore, it should be understood that the conveying directions of the first conveyor line 410 and the second conveyor line 420 are opposite. When the first conveyor line 410 and the second conveyor line 420 are conveying, since the first conveyor line 410 and the second conveyor line 420 are distributed along the first direction and the material picking end of the first conveyor line 410 and the material picking end of the second conveyor line 420 are relatively arranged, the first protective cover 810 on the first conveyor line 410 and the second protective cover 820 on the second conveyor line 420 gradually approach each other. After the first protective cover 810 is conveyed to the material picking end of the first conveyor line 410 and the second protective cover 820 is conveyed to the material picking end of the second conveyor line 420, it is convenient for the picking device to pick up the material and reduce the path required for the picking device to move during the material picking process.

[0071] Specifically, the conveying device 400, the transfer device 500 and the third conveying line 600 are distributed along the second direction, and the picking device and the assembling device 100 can grasp and place the first protective cover 810 and the second protective cover 820 along the second direction. The first direction and the second direction are perpendicular to each other, so that the equipment layout is reasonable and the occupied space is reduced.

[0072] It should be noted that the pressing driving part 220 of the pressing device 200 has a certain volume, and the first material picking head 130a can approach the third conveying line 600 along the second direction to install the first protective cover 810 to the back plate 830. In order to avoid interference between the first material picking head 130a and the pressing device 200, refer to Figure 4 and Figure 6 The clamping arm 132a of the first material picking head 130a extends along the second direction, so that when the first clamping arm 132a installs the first protective cover 810, the driving module 110 and the clamping driving part 131a can be far away from the pressing device 200, thereby avoiding the pressing device 200 from interfering with the assembly process of the first material picking head 130a, so as to facilitate the first material picking head 130a to install the first protective cover 810.

[0073] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
