Description

Technical Field

[0001] This application relates to the field of production equipment technology, and in particular to a sensor element protective cover assembly machine. Background Technology

[0002] In the manufacturing process of some electronic products, multiple protective covers need to be mounted on a backplate to protect the sensing components on the backplate. In related technologies, an assembly robot typically places the protective covers onto the backplate, and a screw-tightening robot then inserts screws through the protective covers and backplate to fix them relatively in place. During the screw-tightening process, the protective covers can easily rotate relative to the backplate. Therefore, during screw-tightening, an assembly robot needs to press the protective covers against the backplate to restrict their rotation. Consequently, while tightening the screws to secure the protective covers and backplate, the assembly robot cannot perform other operations, impacting production efficiency. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a sensor element protective cover assembly machine that can simultaneously install another protective cover onto a backplate while installing fasteners on one of the protective covers, thereby improving production efficiency.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0039] The sensor element protective cover assembly machine of this application is used to assemble a first protective cover 810 and a second protective cover 820 onto a back plate 830 to protect the sensor element on the back plate 830. It should be understood that in some embodiments, the first protective cover 810 and the second protective cover 820 have different shapes, while in other embodiments, the first protective cover 810 and the second protective cover 820 are the same.

[0040] Reference Figure 1 and Figure 2 The sensor element protective cover assembly machine of this application includes: an assembly device 100, a pressing device 200, and a fastening device 300.

[0041] Reference Figure 3 The assembly device 100 is used to install the first protective cover 810 and the second protective cover 820 onto the back plate 830, respectively. (Refer to...) Figure 6 and Figure 7 The pressing device 200 includes a pressing part 210 and a pressing drive part 220. The pressing drive part 220 drives and connects to the pressing part 210, and is used to drive the pressing part 210 to abut against the side of the first protective cover 810 mounted on the back plate 830 away from the back plate 830. The fastening device 300 is used to pass fasteners 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 in the assembly device 100.

[0042] In one specific mode of operation, refer to Figure 3 The assembly device 100 first picks up the first protective cover 810 and the second protective cover 820, and then installs the first protective cover 810 onto the back plate 830, for example, by placing the first protective cover 810 on the back plate 830 or by snapping the first protective cover 810 onto the back plate 830. (See reference...) Figure 6 and Figure 7 Subsequently, the pressing drive unit 220 drives the pressing unit 210 to abut against the side of the first protective cover 810 away from the back plate 830, thereby pressing the first protective cover 810 onto the back plate 830 and fixing the first protective cover 810 relative to the back plate 830. After the pressing unit 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 closer to the mounting 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, by placing the second protective cover 820 on the back plate 830 or by snapping the second protective cover 820 onto the back plate 830. At the same time, the fastening device 300 passes its gripped fasteners through the first protective cover 810 and the back plate 830 to assemble the first protective cover 810 onto the back plate 830.

[0043] Therefore, it should be understood that during the process of the assembly device 100 installing the second protective cover 820 onto the back plate 830, the pressure part 210 remains pressed against the first protective cover 810. This ensures that the first protective cover 810 is fixed relative to the back plate 830 during the fastening device 300's installation of fasteners, preventing the first protective cover 810 from shifting or rotating relative to the back plate 830, thus ensuring assembly quality. Furthermore, due to the fixing effect of the pressure part 210 on the first protective cover 810, the assembly device 100 does not need to coordinate with the fastening device 300. The assembly device 100 does not need to press down on the first protective cover 810 during the fastening device 300's installation of fasteners. Therefore, the installation process of the second protective cover 820 and the installation process of the fasteners on the first protective cover 810 can be performed simultaneously, improving production efficiency.

[0044] In some other operating modes, the assembly device 100 may first grab the first protective cover 810, and after the pressing part 210 presses down the first protective cover 810, the assembly device 100 may then grab the second protective cover 820.

[0045] It should be noted that in the prior art, the first protective cover 810 and the second protective cover 820 are assembled using two separate machines. Therefore, compared with the prior art, the sensor element protective cover assembly machine of this 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, thereby reducing the space occupied by the equipment and saving the production cost of the equipment.

[0046] In one 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 onto the first protective cover 810 and the back plate 830. During the screw-tightening process, the first protective cover 810 is easily rotated relative to the back plate 830. Therefore, under the limiting action of the pressure part 210 and the pressure drive part 220, the rotation of the first protective cover 810 relative to the back plate 830 can be restricted, thus ensuring the installation accuracy of the first protective cover 810. Of course, in other application scenarios, the fastener can also be a pin or rivet, and the fastening device 300 is a robot assembling the corresponding fastener. Specifically, to facilitate the fastening device 300 in acquiring fasteners, the sensor element protective cover assembly machine of this application also includes a fastener feeder.

[0047] It should be understood that, in order to ensure the positional accuracy of the first protective cover 810 relative to the back plate 830, the assembly device 100 maintains a gripping state of the first protective cover 810 before the pressure part 210 abuts against the first protective cover 810, so that the first protective cover 810 remains pressed against the back plate 830, thus preventing the first protective cover 810 from shifting away when the assembly device 100 moves away. Only after the pressure part 210 abuts against the first protective cover 810 will the assembly device 100 move away from the first protective cover 810 before installing the second protective cover 820.

[0048] Regarding the specific form of the assembly device 100:

[0049] In this embodiment, refer to Figure 3 , Figure 4 and Figure 5 The assembly device 100 includes a drive module 110 and at least two mounting modules 120. The drive module 110 drives and connects multiple mounting modules 120 to move the mounting modules 120 relative to the back plate 830. At least one mounting module 120 is used to mount a first protective cover 810 to the back plate 830, and at least one mounting module 120 is used to mount a second protective cover 820 to the back plate 830.

[0050] Understandably, the drive module 110 drives multiple mounting modules 120 simultaneously, so that at least two mounting modules 120 respectively grab the first protective cover 810 and the second protective cover 820, and at least two mounting modules 120 respectively install the first protective cover 810 and the second protective cover 820 onto the back panel 830.

[0051] For example, refer to Figure 3 , Figure 4 and Figure 5There are two mounting modules 120. One mounting module 120 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 onto the back plate 830. 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 onto the back plate 830. For ease of description, the mounting module 120 for installing the first protective cover 810 is defined as the first mounting module 120a, and the mounting module 120 for installing the second protective cover 820 is defined as the second mounting module 120b. The drive module 110 drives the first mounting module 120a and the second mounting module 120b to the loading positions of the first protective cover 810 and the second protective cover 820, respectively, so that the first mounting module 120a and the second mounting module 120b can respectively grasp the first protective cover 810 and the second protective cover 820. The drive module 110 can also drive the first mounting module 120a and the second mounting module 120b to move relative to the back plate 830, so that the first mounting module 120a can install the first protective cover 810 to the corresponding position on the back plate 830, and the second mounting module 120b can install the second protective cover 820 to the corresponding position on the back plate 830. Thus, by using a single drive module 110 to simultaneously drive the first mounting module 120a and the second mounting module 120b, the use of the drive module 110 can be reduced, production costs can be saved, and the space occupied by the equipment can be reduced.

[0052] It should be noted that the first installation module 120a and the second installation module 120b may also include multiple modules to simultaneously grab multiple first protective covers 810 and second protective covers 820, thereby improving production efficiency.

[0053] In other embodiments, the assembly device 100 may also include only an installation module 120 and a drive module 110. The drive module 110 first drives the installation module 120 to grasp 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 down on the first protective cover 810, the drive module 110 drives the installation module 120 to grasp the second protective cover 820 and allows the installation module 120 to complete the installation of the second protective cover 820.

[0054] To avoid interference between the material handling or installation processes of multiple installation modules, please refer to... Figure 3 The installation module 120 includes a material pick-up head 130, and at least one installation module 120 also includes a lifting drive unit 140b, which drives the material pick-up head 130 of the corresponding installation module 120.

[0055] It is understood that at least one installation module 120 includes a lifting drive unit 140b and a picking head 130, and the lifting drive unit 140b can drive the corresponding picking head 130 to rise and fall. Thus, the picking head 130 connected to the lifting drive unit 140b can rise and fall relative to the picking heads 130 in other installation modules 120, so that the picking heads 130 are staggered in the height direction, so that the picking head 130 can pick up materials or install the first protective cover 810 / second protective cover 820, and avoid interference from other picking heads 130 during the material picking or installation process.

[0056] For example, for ease of expression, refer to Figure 4 The material handling head 130 of the first installation module 120a is defined as the first material handling head 130a, referring to... Figure 5 The material handling head 130 of the second installation module 120b is defined as the second material handling head 130b. (Refer to...) Figure 5 The second mounting module 120b also includes a lifting drive unit 140b that drives the second picking head 130b to move up and down. When the first picking head 130a is picking up material or installing the first protective cover 810, the lifting drive unit 140b drives the second picking head 130b to rise above the first picking head 130a, so that the first picking head 130a is lower than the second picking head 130b, facilitating the first picking head 130a's picking up material or installation of the first protective cover 810. When the second picking head 130b is picking up material or installing the second protective cover 820, the lifting drive unit 140b drives the second picking head 130b to descend below the first picking head 130a, facilitating the second picking head 130b's picking up material or installation of the second protective cover 820.

[0057] It should be noted that in some other embodiments, only the first mounting module 120a may include the lifting drive unit 140b, while the second mounting module 120b may not include the lifting drive unit 140b. Alternatively, both the first mounting module 120a and the second mounting module 120b may include the lifting drive unit 140b.

[0058] Specifically, the material handling method of the material handling head 130 includes clamping, vacuum adsorption or magnetic adsorption, etc., and there are no restrictions here.

[0059] To improve the installation accuracy of the first protective cover 810 / second protective cover 820, refer to Figure 3 At least one mounting module 120 also includes a rotary drive unit 150, which drives the picking head 130 connected to the corresponding mounting module 120 to rotate.

[0060] It is understood that the rotary drive unit 150 can drive the picking head 130 to rotate, so as to adjust the horizontal orientation of the first protective cover 810 / second protective cover 820 picked up by the 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.

[0061] For example, refer to Figure 4 and Figure 5 Both the first mounting module 120a and the second mounting module 120b include a rotary drive unit 150. For ease of description, the rotary drive unit 150 of the first mounting module 120a is defined as the first rotary drive unit 150a, and the rotary drive unit 150 of the second mounting module 120b is defined as the second rotary drive unit 150b. The first rotary drive unit 150a drives and connects to the first material handling head 130a to rotate, and the second rotary drive unit 150b drives and connects to the second material handling head 130b to rotate. Specifically, when the second mounting module 120b includes a lifting drive unit 140b, the drive end of the second rotary drive unit 150b is connected to the lifting drive unit 140b, and the drive end of the lifting drive unit 140b drives and connects to the second material handling head 130b. The second rotary drive unit 150b rotates the second material handling head 130b by rotating the lifting drive unit 140b.

[0062] It should be noted that in some other embodiments, only the first mounting module 120a or the second mounting module 120b may include the rotation drive unit 150.

[0063] To facilitate the installation of the first protective cover 810 / second protective cover 820, refer to Figure 3 and Figure 5 At least one mounting module 120 also includes an angle adjustment drive unit 160b, which drives the picking head 130 connected to the corresponding mounting module 120 to tilt relative to the horizontal plane.

[0064] For example, in a specific application scenario, during the process of the second installation module 120b installing the second protective cover 820 onto the back plate 830, one end of the second protective cover 820 needs to be snapped into the back plate 830. The corresponding snap hole on the back plate 830 for the second protective cover 820 faces the horizontal direction, so that the second protective cover 820 cannot be vertically inserted into the back plate 830 along the height direction. To enable one end of the second protective cover 820 to snap into the slot of the back plate 830, the second mounting module 120b further includes an angle adjustment drive unit 160b. After the second mounting module 120b reaches above the back plate 830, the angle adjustment drive unit 160b drives the second picking head 130b to rotate forward by a certain angle, so that the second picking head 130b can tilt the second protective cover 820 relative to the horizontal plane, causing one end of the second protective cover 820 to tilt towards the slot of the back plate 830. This facilitates the subsequent drive module 110 to drive the second picking head 130b to snap the second protective cover 820 into the slot of the back plate 830. After one end of the second protective cover 820 is snapped into the slot, the angle adjustment drive unit 160b drives the second mounting 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, placing the second protective cover 820 flat on the back plate 830, thus completing 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 picking head 130b picks up the second protective cover 820 by vacuum adsorption.

[0065] It is also understandable that in some other application scenarios, the first protective cover 810 can also be snapped onto the back plate 830, and the first mounting module 120a also includes an angle adjustment drive unit 160b.

[0066] It is also understandable that in some other application scenarios, the mounting surface of the back plate 830 corresponding to the first protective cover 810 / second protective cover 820 is tilted relative to the horizontal plane. The angle adjustment drive unit 160b drives the material picking head 130 so that the material picking head 130 can tilt the first protective cover 810 / second protective cover 820 it is gripping relative to the horizontal plane, so as to adjust the posture of the first protective cover 810 / second protective cover 820 to match the tilt angle of the mounting surface of the back plate 830 corresponding to the first protective cover 810 / second protective cover 820.

[0067] It should be noted that before the pressing part 210 comes into contact with the first protective cover 810, the material-grabbing head 130 (i.e., the first material-grabbing head 130a) used to install the first protective cover 810 remains in a gripping state of the first protective cover 810. Only after the pressing part 210 comes into contact with the first protective cover 810 will the first material-grabbing head 130a move away from the first protective cover 810. To avoid the first material-grabbing head 130a interfering with the pressing process of the pressing part 210, refer to... Figure 7The pressing part 210 has a through groove 211, through which the first material take-up head 130a can pass.

[0068] It is understandable that during the process of the pressing drive unit 220 driving the pressing unit 210 to approach the first protective cover 810, the first take-up head 130a can enter the through groove 211 to avoid the pressing unit 210. After the pressing unit 210 comes into contact with the first protective cover 810, the first take-up head 130a can pass through the through groove 211 to move away from the first protective cover 810, thereby ensuring that the operation of the first take-up head 130a and the pressing unit 210 does not interfere with each other.

[0069] To ensure the limiting effect on the first protective cover 810, the first picking head 130a grips the first protective cover 810 by clamping. Specifically, refer to... Figure 4 The first material handling head 130a includes a clamping drive unit 131a and two clamping arms 132a. The clamping drive unit 131a drives the two clamping arms 132a to move the clamping arms 132a closer or further apart to clamp or release the first protective cover 810.

[0070] Specifically, refer to Figure 6 and Figure 7Two clamping arms 132a are distributed along the first direction, and the clamping drive unit 131a can drive the two clamping arms 132a to move closer or further away from each other in the first direction. The through groove 211 extends along the first direction and penetrates one side of the pressing part 210, so that one side of the pressing part 210 forms an opening. The pressing drive unit 220 can drive the pressing part 210 to move horizontally along the first direction and move along the height direction. Therefore, after the first take-up head 130a completes the installation of the first protective cover 810, the pressing drive unit 220 drives the pressing part 210 to move horizontally in the first direction. The pressing part 210 approaches the first take-up head 130a, and the first take-up head 130a enters the through groove 211 from the opening, so that the first take-up head 130a and the pressing part 210 avoid each other, so that the pressing part 210 comes above the first protective cover 810. Subsequently, the pressing drive unit 220 drives the pressing part 210 to descend in the height direction, so that the pressing part 210 abuts against the first protective cover 810. After the pressing part 210 abuts against the first protective cover 810, the drive module 110 drives the first take-up head 130a to rise to pass through the through groove 211 and move away from the first protective cover 810. It should be understood that by opening the through groove 211 to avoid the clamping arm 132a, the movement path of the pressing part 210 can be reduced, thereby reducing 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 groove 211, and the direction of horizontal movement of the pressing part 210 are consistent, so as to reduce the opening area of ​​the through groove 211 and increase the contact area of ​​the pressing part 210 relative to the first protective cover 810, thereby improving the limiting effect of the pressing part 210 on the first protective cover 810. Furthermore, during the process of the two clamping arms 132a releasing the first protective cover 810, the two clamping arms 132a move away from each other along the first direction, and the through groove 211 extending along the first direction can provide the clamping arms 132a with sufficient room for movement.

[0071] Specifically, the pressing drive unit 220 includes a vertical drive cylinder 221 and a horizontal drive cylinder 222. In some embodiments, the horizontal drive cylinder 222 is connected to the vertical drive cylinder 221, and the horizontal drive cylinder 222 drives the pressing unit 210 to move along a first direction via the vertical drive cylinder 221. The vertical drive cylinder 221 is also connected to the pressing unit 210 to move the pressing unit 210 along the height direction. In other embodiments, the vertical drive cylinder 221 is connected to the horizontal drive cylinder 222, and the vertical drive cylinder 221 drives the pressing unit 210 to move along the height direction via the horizontal drive cylinder 222. The horizontal drive cylinder 222 is also connected to the pressing unit 210 to move the pressing unit 210 along the first direction.

[0072] It should be noted that, in this embodiment, after the second protective cover 820 is installed onto the back plate 830, fasteners are needed to pass through the second protective cover 820 and the back plate 830 to fix the second protective cover 820 onto the back plate 830. Therefore, the fastening device 300 is also used to pass fasteners through the second protective cover 820 and the back plate 830. (Refer to...) Figure 5 The pick-up head 130 (i.e., the second pick-up head 130b) for mounting the second protective cover 820 has a through hole 131b for passing through the fastener.

[0073] It is understandable that after the second pick-up head 130b installs the second protective cover 820 onto 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 fix the second protective cover 820 and the back plate 830 relatively. It should be understood that during the process of the fastening device 300 installing the fastener onto the second protective cover 820, the second pick-up head 130b maintains a gripping posture of the second protective cover 820 to prevent the second protective cover 820 from shifting relative to the back plate 830. Furthermore, the through hole 131b on the second pick-up head 130b corresponds to the threaded hole on the second protective cover 820 where the fastener needs to be passed. The fastening device 300 drives the fastener through the through hole 131b, and then through the second protective cover 820 and the back plate 830. It should be understood that by opening a through hole 131b for fasteners to pass through on the second pick-up head 130b, the process of fastening the fastening device 300 to install fasteners can be guided, and the contact area between the second pick-up head 130b and the second protective cover 820 can be guaranteed, thus ensuring the limiting effect of the second pick-up head 130b on the second protective cover 820 when installing fasteners.

[0074] Specifically, to improve production efficiency, the fastening device 300 can simultaneously grip at least two fasteners, so that after one fastener is installed onto the first protective cover 810, the other fastener can be installed onto the second protective cover 820. In some other embodiments, the fastening device 300 may also grip only one fastener at a time, completing the installation of the first protective cover 810 before gripping the other fastener.

[0075] To improve the gripping accuracy of the assembly device 100 on 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 this 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 pick up the first protective cover 810 and the second protective cover 820 on the conveying device 400 and transfer device 500. The transfer device 500 is used to pre-position the first protective cover 810 and the second protective cover 820. The assembly device 100 is also used to pick up the first protective cover 810 and the second protective cover 820 on the transfer device 500.

[0076] Understandably, after the conveying device 400 delivers the first protective cover 810 and the second protective cover 820 to their positions, the picking device can pick up the first protective cover 810 and the second protective cover 820 from the conveying device 400, either separately or simultaneously, and transfer them to the transfer device 500. The transfer device 500 pre-positions the first protective cover 810 and the second protective cover 820 to adjust their posture. Subsequently, the assembly device 100 picks up the first protective cover 810 and the second protective cover 820 from the transfer device 500, either separately or simultaneously. It should be understood that by pre-positioning the first protective cover 810 and the second protective cover 820 through the transfer device 500, the posture of the first protective cover 810 and the second protective cover 820 is accurate when the material picking head 130 of the assembly device 100 picks up the material, ensuring that the material picking head 130 can grab the corresponding positions of the first protective cover 810 and the second protective cover 820. Furthermore, the pre-adjustment of the posture is beneficial for the subsequent installation of the first protective cover 810 and the second protective cover 820 by the material picking head 130.

[0077] Specifically, to improve production efficiency, the picking device has at least two sets of picking heads. These two sets of picking heads respectively grasp the first protective cover 810 and the second protective cover 820, simultaneously transferring the first protective cover 810 and the second protective cover 820 to the transfer device 500. This reduces the number of times the picking device travels back and forth between the conveying device 400 and the transfer device 500, thereby improving production efficiency. Furthermore, the drive module 110 drives the first picking head 130a and the second picking head 130b close to the transfer device 500, so that the first picking head 130a grasps the first protective cover 810 at the transfer device 500, and the second picking head 130b grasps the second protective cover 820 at the transfer device 500. Subsequently, the first picking head 130a and the second picking head 130b are driven together to approach the back plate 830, further reducing the number of times the picking head 130 travels back and forth between the transfer device 500 and the back plate 830, thus improving production efficiency.

[0078] Specifically, regarding the specific form of the transfer device 500, in this embodiment, the transfer device 500 includes multiple receiving cavities, which are used to receive the first protective cover 810 or the second protective cover 820. Each receiving cavity is provided with at least one push plate, which is movable to retract the receiving cavity and push the first protective cover 810 or the second protective cover 820 in the receiving cavity to adjust the posture of the first protective cover 810 and the second protective cover 820.

[0079] To improve production efficiency, the sensor element protective cover assembly machine of this 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.

[0080] Understandably, the assembly device 100 can install the first protective cover 810 and the second protective cover 820 onto the back plate 830 on the third conveyor line 600, the fastening device 300 can pass 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. Therefore, the assembly of the first protective cover 810 and the second protective cover 820 can be completed simultaneously on the third conveyor line 600 without the need to transfer the back plate 830. After the back plate 830 is assembled, it can be transferred via the third conveyor line 600 for unloading or conveyed to the next production process, thereby improving production efficiency. Furthermore, it reduces the equipment used for transferring the back plate 830, reduces equipment space occupation, and reduces production costs.

[0081] Specifically, in order to ensure the correct orientation of the first protective cover 810 and the second protective cover 820, refer to Figure 2 A detection device 700 is installed between the third conveyor line 600 and the transfer device 500. After the assembly device 100 picks up the first protective cover 810 and the second protective cover 820, it moves the first protective cover 810 and the second protective cover 820 above 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 onto the back plate 830. If the posture is incorrect, the detection device 700 can feed back the signal to the rotary drive unit 150, which adjusts the posture of the first protective cover 810 or the second protective cover 820 on the picking head 130 by rotating the picking head 130.

[0082] To save space occupied by the equipment, refer to Figure 1 and Figure 2 The assembly device 100, fastening device 300, transfer device 500 and picking device are all located between the conveying device 400 and the third conveying line 600.

[0083] It is understood that the conveying device 400 and the third conveying line 600 extend along the second direction and are relatively parallel. The conveying device 400 and the third conveying line 600 are spaced apart, 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 conveying line 600 so as to utilize the space occupied by the equipment by utilizing the space between the conveying device 400 and the third conveying line 600.

[0084] Specifically, the picking device is installed between the conveying device 400 and the transfer device 500 to facilitate the picking device transferring 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 installed between the transfer device 500 and the third conveyor line 600 to facilitate the assembly device 100 transferring the first protective cover 810 and the second protective cover 820 at the transfer device 500 to the third conveyor line 600.

[0085] Specifically, to facilitate the pressing device 200 in pressing the back plate 830 on the third conveyor line 600, the pressing device 200 is mounted above the third conveyor line 600 to utilize vertical space and reduce the space occupied by the equipment. Furthermore, since the third conveyor line 600 extends along a first direction and conveys the back plate 830 along that direction, the pressing drive unit 220 can drive the pressing unit 210 to move horizontally along the first direction, consistent with the extension direction of the third conveyor line 600. This prevents the movement trajectory of the pressing unit 210 from exceeding the top of the third conveyor line 600, thus avoiding interference with the movement of other equipment.

[0086] Specifically, the conveying device 400 includes a first conveyor line 410 and a second conveyor line 420. The first conveyor line 410 is used to convey a first protective cover 810, and the second conveyor line 420 is used to convey a second protective cover 820. The first conveyor line 410 and the second conveyor line 420 are distributed along a first direction, and the picking ends of the first conveyor line 410 and the second conveyor line 420 are opposite to each other. It can be understood that the first protective cover 810 and the second protective cover 820 are conveyed by the first conveyor line 410 and the second conveyor line 420 respectively, so as to facilitate the picking device to pick up the materials. 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 picking end of the first conveyor line 410 and the picking end of the second conveyor line 420 are arranged opposite to each other, 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 picking end of the first conveyor line 410 and the second protective cover 820 is conveyed to the picking end of the second conveyor line 420, it is convenient for the picking device to pick up the material and reduce the path that the picking device needs to move during the picking process.

[0087] Specifically, the conveying device 400, the transfer device 500, and the third conveyor line 600 are distributed along the second direction, and the picking device and the assembly device 100 are able to pick up and place the first protective cover 810 and the second protective cover 820 along the second direction. The first and second directions are perpendicular to each other to make the equipment layout reasonable and reduce the space occupied.

[0088] It should be noted that the pressing drive unit 220 of the pressing device 200 has a certain volume, and the first picking head 130a can approach the third conveyor line 600 along the second direction to install the first protective cover 810 onto the back plate 830. To avoid interference between the first picking head 130a and the pressing device 200, refer to... Figure 4 and Figure 6 The clamping arm 132a of the first picking head 130a extends along the second direction so that when the first protective cover 810 is installed on the first clamping arm 132a, the drive module 110 and the clamping drive part 131a can be far away from the pressing device 200, thereby avoiding interference from the pressing device 200 to the assembly process of the first picking head 130a, so as to facilitate the installation of the first protective cover 810 on the first picking head 130a.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
