[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0025] In the present application, the term "plurality" refers to two or more. In addition, it should be understood that in the description of the present application, the terms "first", "second", etc. are only used for the purpose of distinguishing descriptions, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying an order.

[0026] In the description of the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0027] See also Figure 1 , Figure 1 A processing device 100 provided in an embodiment of the present application is shown. The processing device 100 may include a transmission device 101 and a screw installation device 102. The transmission device 101 can receive a workpiece 200 and drive the workpiece 200 to move along a preset direction to achieve the transmission of the workpiece 200. The workpiece 200 may include a plurality of installation positions, each of which requires tightening a screw to complete the installation of the screw on the workpiece 200. The screw installation device 102 may be located on one side of the transmission device 101. The screw installation device 102 can move the screw to move the screw to the installation position and tighten the screw to achieve the installation of the screw on the workpiece 200.

[0028] In the embodiment of the present application, there is no specific limitation on the type of the workpiece 200. For example, the workpiece 200 may be a semi-finished product of an electronic product, and the electronic product may include, but is not limited to, a tablet computer, a laptop computer, a smart phone, and a smart watch.

[0029] In the embodiment of the present application, there is no specific limitation on the type of the transmission device 101. For example, the transmission device 101 may be, but is not limited to, a synchronous belt device.

[0030] For example, the transmission device 101 may be a synchronous belt device, wherein the principle of the transmission device 101 transmitting the workpiece 200 may be the same as or similar to the principle of the transmission device 101 transmitting the workpiece 200 in the related art, and will not be described in detail herein.

[0031] In the embodiment of the present application, the length direction, width direction and height direction of the processing equipment 100 can be defined as the first horizontal direction, the second horizontal direction and the vertical direction respectively. For example, the first horizontal direction can be Figure 1 The X direction and its direction shown, the second horizontal direction can be Figure 1 The Y direction and its reverse direction are shown, and the vertical direction can be Figure 1 The Z direction and its opposite direction are shown.

[0032] For example, the transmission device 101 and the screw installation device 102 can be spaced apart in the first horizontal direction, and the transmission device 101 can transmit the workpiece 200 along the second horizontal direction. The workpiece 200 can be placed flat on the transmission device 101, and the workpiece 200 can be located on a surface where the first horizontal direction and the second horizontal direction coexist and are perpendicular to the vertical direction.

[0033] Please also read Figure 2 and Figure 3 The screw installation device 102 may include a machine platform 10, a motion mechanism 20, a connecting member 30, a driving mechanism 40, and a magnetic member 50 ( Figure 5 ) and mounting mechanism 60.

[0034] The machine 10 can be placed or fixedly installed in a designated working area. The motion mechanism 20 can be fixedly installed on the machine 10. The connecting member 30 can be fixedly connected to the motion mechanism 20, and the motion mechanism 20 can drive the connecting member 30 to rotate and / or move, so that the connecting member 30 can be close to or away from the transmission device 101 and the workpiece 200 on the transmission device 101.

[0035] Please also read Figure 4 , the driving mechanism 40 may include a guide frame 41 and a plurality of electromagnets 42. The guide frame 41 may be fixedly mounted on the connecting member 30 to move synchronously with the connecting member 30. The plurality of electromagnets 42 may be fixedly mounted on the guide frame 41 and arranged in a preset direction. The mounting mechanism 60 may be movably connected to the guide frame 41 along the arrangement direction of the plurality of electromagnets 42. The magnetic member 50 may be fixedly mounted on the mounting mechanism 60 and arranged corresponding to the plurality of electromagnets 42; when the plurality of electromagnets 42 are powered on, magnetic force may be generated, and the magnetic member 50 may be driven by the magnetic force to move in a preset direction, so that the mounting mechanism 60 moves synchronously; when the plurality of electromagnets 42 are powered off, the magnetic member 50 may magnetically absorb any one or more electromagnets 42 to stop moving, and remain relatively fixed with the plurality of electromagnets 42. The mounting mechanism 60 may extend in a vertical direction. One end of the mounting mechanism 60 in the vertical direction may absorb a screw, and the mounting mechanism 60 may drive the screw to be tightened to the mounting position on the workpiece 200 to complete the installation of the screw on the workpiece 200.

[0036] For example, the installation position may be located on the top surface of the workpiece 200 . The bottom of the installation mechanism 60 can absorb the screw, and the installation mechanism 60 can drive the screw located at the bottom of the installation mechanism 60 to rotate, so that the screw is tightened at the installation position on the workpiece 200 .

[0037] It can be understood that when the transmission device 101 moves the workpiece 200 to the designated position 1011, the transmission device 101 can stop moving the workpiece 200 to keep the workpiece 200 still. Then, the motion mechanism 20 can drive the connection member 30 to move, so that the installation mechanism 60 moves to the top of the workpiece 200, and then the driving mechanism 40 can drive the installation mechanism 60 to move, so that the installation mechanism 60 is aligned with the installation position in the vertical direction, and then the installation mechanism 60 can install the screw at the installation position.

[0038] It can be understood that the principle of driving the magnetic part 50 to move after the electromagnet 42 is energized can be a common principle in the relevant field, and the embodiments of the present application will not elaborate on this; its specific principle can refer to the magnetic levitation principle and the working principle of the permanent magnet synchronous motor.

[0039] It can be understood that the movement of the magnetic member 50 driven by the electromagnet 42 can make the installation mechanism 60 move synchronously, and realize the magnetic suspension connection between the installation mechanism 60 and the driving mechanism 40. Under the cooperation of the driving mechanism 40 and the motion mechanism 20, the installation mechanism 60 can be driven to approach the corresponding installation position in the first horizontal direction and the second horizontal direction. Then the installation mechanism 60 can move the adsorbed screw to the installation position and tighten the screw to realize the installation of the screw.

[0040] Thus, compared with the general technology of driving the installation mechanism 60 to move by a motor or other equipment, the installation mechanism 60 is driven to move by the cooperation of the electromagnet 42 and the magnetic part 50, so that the power loss of the installation mechanism 60 when it is close to or away from the installation position is lower, which can reduce the waste of resources.

[0041] At the same time, the moving mechanism 20 and the driving mechanism 40 can automatically drive the installation mechanism 60 to approach or move away from the installation position, and the installation mechanism 60 can automatically realize the tightening and installation of the screws, thereby automating the process of screw installation on the workpiece 200 and reducing manpower loss; in the process of the driving mechanism 40 and the moving mechanism 20 driving the installation mechanism 60 to move, the installation mechanism 60 connected to the driving mechanism 40 can maintain a vertical setting, that is, it can keep its extension direction coincident with the vertical direction, so that when the installation mechanism 60 tightens the screw, the vertical relationship between the installation mechanism 60 and the horizontal workpiece 200, and the vertical relationship between the screw and the horizontal workpiece 200 can be maintained; the stability of the screw installation can be improved, the probability of thread slippage between the installation mechanism 60 and the screw during screw installation can be reduced, and the probability of the screw tilting when in contact with the workpiece 200, thereby reducing the probability of the screw needing to be unscrewed and reinstalled, thereby improving the efficiency of screw installation.

[0042] In the embodiment of the present application, there is no specific limitation on the type of the motion mechanism 20. For example, the motion mechanism 20 may be a multi-degree-of-freedom robotic arm.

[0043] In the embodiments of the present application, there is no specific limitation on the fixing method during the fixed installation and fixed connection. For example, the fixing method may include bolt fixing, welding fixing, integral molding fixing, and buckle fixing.

[0044] In some embodiments, there may be multiple mounting mechanisms 60, and multiple mounting mechanisms 60 may be arranged at intervals. There may be multiple magnetic members 50, each magnetic member 50 corresponds to one mounting mechanism 60, and at least one magnetic member 50 may be fixedly connected to each mounting mechanism 60. Multiple mounting mechanisms 60 are movably connected to the guide frame 41 along a preset direction.

[0045] It can be understood that after the multiple electromagnets 42 are energized, multiple installation mechanisms 60 can be driven to move synchronously. Each installation mechanism 60 can realize the adsorption and installation of a screw. In this way, when multiple installation mechanisms 60 are located above the workpiece 200, the driving mechanism 40 can cooperate with the motion mechanism 20 to drive the multiple installation mechanisms 60 to move to the corresponding installation positions one by one, and each installation mechanism 60 can install the screw at the corresponding installation position, thereby realizing the installation of multiple screws on the workpiece 200. In this way, the process of the installation mechanism 60 installing a screw each time and then re-acquiring the screw can be saved. The installation mechanism 60 with screws absorbed by multiple installation mechanisms 60 can install screws at multiple installation positions respectively, which can improve the efficiency of screw installation.

[0046] Please also read Figure 5 In some embodiments, the guide frame 41 may be annular, and the preset direction is a direction surrounding the guide frame 41. The axial direction of the central axis of the guide frame 41 coincides with the vertical direction. A plurality of magnetic members 50 are fixedly mounted on the inner wall of the guide frame 41. The guide frame 41 may surround a receiving space 411. A plurality of mounting mechanisms 60 are at least partially accommodated in the receiving space 411, and the magnetic member 50 on each mounting mechanism 60 is arranged toward the inner wall of the guide frame 41.

[0047] In this way, multiple installation mechanisms 60 can be arranged on the guide frame 41 at intervals along the direction surrounding the guide frame 41. Multiple electromagnets 42 can be energized to drive multiple installation mechanisms 60 to move along the direction surrounding the guide frame 41; through movement, each installation mechanism 60 can move to the top of the corresponding installation position and install the screws at the corresponding installation position.

[0048] In other embodiments, the guide frame 41 is annular, multiple magnetic members 50 can be installed on the outer wall of the guide frame 41, multiple installation mechanisms 60 can be located outside the guide frame 41, and the magnetic members 50 on each installation mechanism 60 are arranged toward the outside of the guide frame 41.

[0049] In some embodiments, the screw installation device 102 may further include a receiving box 70. The receiving box 70 may be fixedly mounted on the machine table 10. The receiving box 70 receives a plurality of screws, and the plurality of screws may be arranged in the receiving box 70 along a preset rule. The motion mechanism 20 and the driving mechanism 40 may cooperate to drive the plurality of installation mechanisms 60 to move one by one above the receiving box 70, and obtain screws from the receiving box 70 respectively.

[0050] Please also read Figure 6 In some embodiments, the screw installation device 102 may further include an image acquisition component 80 and a processor 90. The image acquisition component 80 is fixedly mounted on the connecting component 30 and can move synchronously with the connecting component 30. The motion mechanism 20 can drive the image acquisition component 80 to move above the workpiece 200, and then the image acquisition component 80 can shoot the workpiece 200 to obtain a detection image corresponding to the workpiece 200.

[0051] The processor 90 can be connected to the motion mechanism 20, the drive mechanism 40, each installation mechanism 60 and the image acquisition component 80 for communication. The processor 90 can control the operation of the motion mechanism 20, the drive mechanism 40 and each installation mechanism 60. The image acquisition component 80 can output the detection image to the processor 90. After receiving the detection image, the processor 90 can obtain the installation position from the detection image, and control the motion mechanism 20, the drive mechanism 40 and the multiple installation mechanisms 60 to work according to the number of installation positions, so that the multiple installation mechanisms 60 move one by one to the top of the receiving box 70 and absorb the screws, so that the number of screws absorbed by the multiple installation mechanisms 60 is equal to the number of installation positions; the processor 90 can also assign a corresponding installation position to each installation mechanism 60 that absorbs the screws according to the location of the multiple installation positions on the workpiece 200, and control the motion mechanism 20, the drive mechanism 40 and the multiple installation mechanisms 60 to work, so that each installation mechanism 60 moves to the top of the corresponding installation position in turn, and each installation mechanism 60 tightens the screws on the workpiece 200 to complete the installation of multiple screws on the workpiece 200.

[0052] In the embodiments of the present application, the communication connection method is not specifically limited. For example, the communication connection may be a wired communication connection implemented by a device such as a signal line. For another example, the communication connection may be a wireless communication connection implemented by technologies such as 3G, 4G, 5G, Bluetooth, or wireless LAN.

[0053] It is understood that the processor 90 can generate a one-dimensional coordinate system after receiving the detection image, and project the detection image into the coordinate system. The processor 90 can confirm the number and position of the installation positions in the detection image based on the image features of the known installation positions, and obtain the coordinates of each installation position in the coordinate system. The processor 90 can control the drive mechanism 40 and the motion mechanism 20 to work according to the coordinates of each installation position, so that each installation mechanism 60 moves to the corresponding coordinates, and the processor 90 can control each installation mechanism 60 to install the screws at the corresponding installation position.

[0054] Among them, the principle that the processor 90 recognizes the detection image and obtains the installation position therefrom, and the principle that the processor 90 generates a coordinate system and obtains the coordinates of each installation position are common principles in the relevant fields and will not be repeated here.

[0055] In the embodiments of the present application, there is no specific limitation on the type of processor 90. For example, processor 90 may be a general-purpose central processing unit (CPU), a microprocessor, an application-specific integrated circuit (ASIC), or one or more integrated circuits for controlling the execution of the above program.

[0056] In the embodiment of the present application, there is no specific limitation on the type of the image acquisition component 80. For example, the image acquisition component 80 can be, but is not limited to, a CCD camera.

[0057] It can be understood that the image acquisition component 80 can also shoot the receiving box 70 when the multiple installation mechanisms 60 need to absorb screws to obtain a detection image. The processor 90 can control the motion mechanism 20 and the drive mechanism 40 to work according to the position of the screw in the detection image, so that the multiple installation mechanisms 60 can sequentially obtain screws from the receiving box 70. The principle that the processor 90 controls the motion mechanism 20, the drive mechanism 40 and the multiple installation mechanisms 60 to work according to the detection image so that the multiple installation mechanisms 60 absorb screws can be the same or similar to the principle that the processor 90 controls the multiple installation mechanisms 60 to install screws according to the detection image, and will not be repeated here.

[0058] It is understood that the processor 90 can be connected to the transmission device 101. When the transmission device 101 stops working and the workpiece 200 is maintained at the specified position 1011, the transmission device 101 can output a trigger signal to the processor 90, and the processor 90 can start to control the motion mechanism 20, the driving mechanism 40 and the plurality of mounting mechanisms 60 to work.

[0059] In some cases, the processor 90 may be electrically connected to the multiple electromagnets 42. The processor 90 may be electrically connected to a power supply device (not shown). The processor 90 may transmit the current generated by the power supply device to the multiple electromagnets 42, so that the multiple electromagnets 42 are powered on; and the processor 90 may also block the transmission of the current of the power supply device to the multiple electromagnets 42, so that the multiple electromagnets 42 are powered off. In this way, the processor 90 can control the operation and stop of the multiple electromagnets 42, so as to control the movement and stop of the multiple mounting mechanisms 60.

[0060] In other cases, the multiple electromagnets 42 may be electrically connected to a power supply device (not shown). The processor 90 may be in communication with the power supply device and may control the operation and stop of the power supply device. The processor 90 may control the operation of the power supply device so that the current generated by the power supply device is transmitted to the multiple electromagnets 42 so that the multiple electromagnets 42 are powered on; and the processor 90 may also control the power supply device to stop working so that the multiple electromagnets 42 are powered off. In this way, the processor 90 may control the operation and stop of the multiple electromagnets 42 so as to control the movement and stop of the multiple mounting mechanisms 60.

[0061] In some embodiments, the screw mounting device 102 may further include a position detection member 110. The position detection member 110 is fixedly mounted on the guide frame 41 and is in communication connection with the processor 90. The side of the mounting mechanism 60 facing the center of the receiving space 411 may be defined as the inner side, and the other side as the outer side. A sensing sheet 61 may be fixedly mounted on the outer side of each mounting mechanism 60. The sensing sheet 61 may extend in a direction perpendicular to the vertical direction. When the mounting mechanism 60 moves in a direction surrounding the guide frame 41, the sensing sheet 61 may move synchronously and move to a position corresponding to the position detection member 110, so that the position detection member 110 may detect the passage of the sensing sheet 61. The position detection member 110 may output a position detection signal to the processor 90 when detecting the passage of the sensing sheet 61, and the processor 90 may control the drive mechanism 40 to stop working after receiving the position detection signal, thereby stopping the rotation of the plurality of mounting mechanisms 60.

[0062] The guide frame 41 has a working position (not shown), which is located on the side of the guide frame 41 facing the transmission device 101 in the first horizontal direction. When the screw installation device 102 installs the screw, the motion mechanism 20 and the drive mechanism 40 work to drive the installation mechanism 60 to move. Every time the processor 90 receives a position detection signal, the processor 90 can control the drive mechanism 40 to stop working. At this time, there is a mounting mechanism 60 located at the working position. The mounting mechanism 60 located at the working position can be located directly above the corresponding mounting position in the vertical direction and aligned with the mounting position. The mounting mechanism 60 located at the working position can start to install the screw at the mounting position. Then the processor 90 can control the motion mechanism 20 and the drive mechanism 40 to work here until the processor 90 receives a position detection signal again, and the processor 90 can control the drive mechanism 40 to stop again and make the mounting mechanism 60 located at the working position install the screw.

[0063] It can be understood that, through the detection of the sensing sheet 61 by the position detection member 110, the processor 90 can limit the angular displacement distance of the multiple mounting mechanisms 60. The processor 90 can timely control the multiple mounting mechanisms 60 to stop rotating when one mounting mechanism 60 moves to the working position, so that the mounting mechanism 60 at the working position can be screwed.

[0064] In some cases, when the processor 90 receives the position detection signal, the motion mechanism 20 and the drive mechanism 40 can be controlled to stop working synchronously. In other cases, when the processor 90 receives the position detection signal, the drive mechanism 40 can be controlled to stop working, and the motion mechanism 20 can automatically stop working when the driving connection member 30 is moved to the corresponding position and rotated to the corresponding angle, wherein the corresponding position and angle of the connection member 30 can correspond to the position of the installation position corresponding to the installation mechanism 60 located at the working position on the workpiece 200 when the drive mechanism 40 stops working.

[0065] Please also read Figure 7 and Figure 8 In some embodiments, each mounting mechanism 60 may include a mounting seat 62 , a guide wheel 63 , a first connecting seat 64 , an electric screwdriver 65 and a driving member 66 .

[0066] The magnetic member 50 can be fixedly connected to the mounting seat 62 and is located on one side of the mounting seat 62 in a direction perpendicular to the vertical direction. The mounting seat 62 extends in the vertical direction. Two groups of guide wheels 63 can be provided, and the two groups of guide wheels 63 are arranged at intervals in the vertical direction and are respectively located on both sides of the guide frame 41 in the vertical direction. The arc surfaces of the two groups of guide wheels 63 can respectively abut against the two sides of the guide frame 41 in the vertical direction. The magnetic member 50 is located between the two groups of guide wheels 63. In each group of guide wheels 63, the number of guide wheels 63 can be multiple, and multiple guide wheels 63 are arranged at intervals. The axial direction of the central axis of rotation of each guide wheel 63 is perpendicular to the vertical direction. The two groups of guide wheels 63 can realize the clamping of the guide frame 41; the guide frame 41 can realize the acceptance of the installation mechanism 60 by receiving the guide wheels 63, and each of its mounting seats 62 can realize relative fixation on the guide frame 41 in the vertical direction.

[0067] The side of the mounting base 62 facing the center of the receiving space 411 can be defined as the inner side, and the other side as the outer side. The magnetic member 50 can be fixedly mounted on the outer side of the mounting base 62. The first connecting base 64 can be fixedly mounted on the inner side of the mounting base 62. The electric screwdriver 65 can be provided with the first connecting base 64 in the vertical direction, and can be movably connected to the first connecting base 64 in the vertical direction. The bottom of the electric screwdriver 65 in the vertical direction is used to connect with the screw and to align with the corresponding installation position. The driving member 66 is fixedly connected to the electric screwdriver 65. The driving member 66 is used to drive the electric screwdriver 65 to move in the vertical direction, so that the screw connected to the electric screwdriver 65 is close to the installation position, and the bottom of the electric screwdriver 65 is away from the installation position. The electric screwdriver 65 can drive the screw to rotate, so that the screw is tightened at the installation position. The processor 90 can be connected to the driving member 66 and the electric screwdriver 65 in communication to control the operation and stop of the driving member 66 and the electric screwdriver 65.

[0068] It can be understood that the electric screwdriver 65 can be a common tool in the relevant field, and the principle of the electric screwdriver 65 driving the screw to rotate can be a common technology in the relevant field, which will not be repeated here. It can be understood that when the bottom of the electric screwdriver 65 can be provided with a screwdriver head 651, the shape of the screwdriver head 651 can be adapted to the shape of the notch on the screw. When the screwdriver head 651 is inserted into the notch and there is no interference between the inner wall of the notch and the screwdriver head 651, the electric screwdriver 65 is connected to the screw. At this time, the electric screwdriver 65 works, and the screwdriver head 651 can be rotated, driving the screw to rotate synchronously.

[0069] When the mounting mechanism 60 moves to above the corresponding mounting position, the processor 90 can control the driving member 66 to work, and the driving member 66 can drive the electric screwdriver 65 to descend, and the electric screwdriver 65 can push the screw to descend synchronously, so that the bottom end of the screw enters the mounting hole of the mounting position (not shown in the figure), and then the processor 90 can control the electric screwdriver 65 to work, and the electric screwdriver 65 can drive the screw to rotate, and at the same time the electric screwdriver 65 can make the screw head 651 press the screw downward, or at the same time the driving member 66 can drive the electric screwdriver 65 to continue to descend to press the screw so that the screw is screwed into the screw hole.

[0070] When the screw rotation time reaches a preset time, or the torque of the electric screwdriver 65 driving the screw to tighten reaches a preset torque, the electric screwdriver 65 can stop working. Then the processor 90 can control the driving member 66 to work, and the driving member 66 can drive the electric screwdriver 65 to rise, so that the electric screwdriver 65 is away from the workpiece 200. Then the processor 90 can control the driving mechanism 40 and the motion mechanism 20 to work, so that another installation mechanism 60 moves to the top of the corresponding installation position and installs the screw at the installation position.

[0071] It can be understood that the principle of making the screwdriver bit 651 press the screw when the electric screwdriver 65 is working, and the principle of controlling the electric screwdriver 65 to stop working by preset time or preset torque, can be common principles in the relevant fields and will not be repeated here.

[0072] In the embodiment of the present application, there is no specific limitation on the type of the driving member 66. For example, the driving member 66 may be, but is not limited to, a cylinder or a linear motor.

[0073] In the embodiment of the present application, there is no specific limitation on the installation position of the driving member 66. For example, the stator portion of the driving member 66 can be fixedly installed on the mounting seat 62 and / or the first connecting seat 64, and the movable portion can be fixedly connected to the electric screwdriver 65. For another example, the driving member 66 can be integrated into the mounting seat 62 and / or the first connecting seat 64, and the movable portion of the driving member 66 can extend out of the mounting seat 62 and / or the first connecting seat 64 in a direction perpendicular to the vertical direction, and be fixedly connected to the electric screwdriver 65.

[0074] For example, Figure 7 and Figure 8 As shown, the driving member 66 is a cylinder, the cylinder body of the driving member 66 can be fixedly mounted on a connecting plate fixedly connected to the electric screwdriver 65, the piston rod of the driving member 66 can be fixedly connected to the first connecting seat 64, and the piston rod of the driving member 66 can move in the vertical direction to drive the electric screwdriver 65 to move in the vertical direction relative to the first connecting seat 64 and the mounting seat 62.

[0075] It can be understood that each sensing sheet can be located on one side of the guide frame 41 in the vertical direction, and can be arranged to avoid the corresponding plurality of guide wheels 63 .

[0076] In some embodiments, each mounting mechanism 60 may further include a second connection seat 67 and a suction nozzle 68. The second connection seat 67 may be fixedly mounted on the inner side of the mounting seat 62 and spaced apart from the first connection seat 64 in the vertical direction. The second connection seat 67 is located below the first connection seat 64. The suction nozzle 68 penetrates the second connection seat 67 in the vertical direction and is fixedly connected to the second connection seat 67. The bottom of the suction nozzle 68 forms the bottom of the corresponding mounting mechanism 60. The top of the suction nozzle 68 is provided with a connection hole 681, and the bottom is provided with a suction hole 682, and the suction hole 682 is connected to the connection hole 681. The suction nozzle 68 can suck the screw into the suction nozzle 68 through the suction hole 682 by negative pressure. When the electric screwdriver 65 descends in the vertical direction, the screwdriver head 651 can extend into the connection hole 681 and connect with the screw in the suction nozzle 68; then the screwdriver head 651 can push the screw out of the suction hole 682 and enter the screw hole on the workpiece 200, and then the electric screwdriver 65 can tighten the screw on the workpiece 200.

[0077] It is understood that the suction nozzle 68 can be connected to a suction device (not shown) through an air pipe (not shown). When the suction device is working, the suction device extracts air through the suction nozzle 68, thereby generating negative pressure at the suction hole 682, so that the screw close to the suction hole 682 can be sucked into the suction nozzle 68 under the action of the negative pressure.

[0078] In some cases, the suction nozzles 68 in the plurality of mounting mechanisms 60 are respectively connected to a plurality of suction devices. The processor 90 can be in communication connection with each suction device. The processor 90 can control the corresponding suction device to work when a mounting mechanism 60 sucks a screw, and control the corresponding suction device to stop working when the mounting mechanism 60 tightens the screw on the workpiece 200.

[0079] In other cases, multiple mounting mechanisms 60 can be connected to the same air extraction device, and each mounting mechanism 60 can be connected to a solenoid valve (not shown), and connected to a pipe connected to the air extraction device through the solenoid valve. The processor 90 can be connected to each solenoid valve in communication. The air extraction device can continue to work. The processor 90 can control the corresponding solenoid valve to open when a mounting mechanism 60 sucks a screw, and control the corresponding solenoid valve to close when the mounting mechanism 60 tightens the screw on the workpiece 200.

[0080] It can be understood that when the installation mechanism 60 finishes installing the screws, the suction nozzle 68 can stop generating negative pressure, thereby reducing the occurrence of foreign matter being accidentally sucked into the suction nozzle 68, and reducing the occurrence of foreign matter entering the suction nozzle 68 causing blockage and damage to the suction nozzle 68.

[0081] In still other cases, the vacuum device may remain connected and communicated with the plurality of suction nozzles 68 , and when the screw mounting device 102 is working, the vacuum device may continue to work to maintain the negative pressure effect of the plurality of suction nozzles 68 at the suction hole 682 .

[0082] It can be understood that the screwdriver bit 651 of the electric screwdriver 65 can push the screw so that the screw overcomes the suction force of the suction nozzle 68 and extends out of the suction hole 682.

[0083] It can be understood that when the screw installation is completed at each installation position on the workpiece 200, that is, the screw installation is completed on the workpiece 200, the processor 90 can output a trigger signal to the transmission device 101, and the transmission device 101 can work to continue to transmit the workpiece 200 on which the screw installation is completed, and continue to transmit the workpiece 200 on which the screw installation has been completed to the designated position 1011, so that the screw installation device 102 continues to install screws on the workpiece 200 at the designated position 1011.

[0084] Through the screw installation device 102 and the processing equipment 100 provided by the embodiment of the present application, when the workpiece 200 moves to the designated position 1011 and stops moving, the processor 90 can control the motion mechanism 20 to work, so that the image acquisition component 80 moves to the top of the workpiece 200 and captures the detection image. After the image acquisition component 80 outputs the detection image to the processor 90, the processor 90 can determine the number and position of the installation positions on the workpiece 200 through the detection image, and then control the motion mechanism 20 and the driving mechanism 40 to work, so that the multiple installation mechanisms 60 move to the top of the receiving box 70 in sequence, and the multiple installation mechanisms 60 can sequentially absorb screws from the receiving box 70.

[0085] After each installation mechanism 60 completes the absorption of the screw, the processor 90 can control the motion mechanism 20 to work, so that the multiple installation mechanisms 60 move to the top of the workpiece 200. Then, the processor 90 can control the driving mechanism 40 and the motion mechanism 20 to work together, so that the multiple installation mechanisms 60 move to the working position in sequence, and the installation mechanism 60 located at the working position is aligned with the corresponding installation position. After each installation mechanism 60 is aligned with the corresponding installation position, the corresponding driving member 66 can drive the electric screwdriver 65 to descend to approach the workpiece 200, and the screw head 651 of the electric screwdriver 65 enters the connection hole 681 during the descent process and is connected with the screw inside the suction nozzle 68; the electric screwdriver 65 continues to descend, and can push the screw to move synchronously, so that the screw extends out of the suction hole 682 and enters the screw hole on the corresponding installation position. Then the processor 90 can control the corresponding electric screwdriver 65 to work, and the corresponding electric screwdriver 65 can drive the screw to rotate so that the screw is tightened at the installation position.

[0086] In this way, the cooperation of the motion mechanism 20 and the driving mechanism 40 can move the installation mechanism 60 to a position corresponding to the installation position, and then the installation mechanism 60 that has absorbed the screw can automatically tighten the screw at the installation position to complete the installation of the screw. This can reduce the loss of manpower during the screw installation process and improve efficiency.

[0087] At the same time, the driving mechanism 40 drives the magnetic member 50 to move through the magnet generated by the electromagnet 42, thereby driving the installation mechanism 60 to move, which can reduce the energy loss required to drive the installation mechanism 60 to move.

[0088] It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and that the present application can be implemented in other specific forms without departing from the spirit or basic features of the present application. Therefore, no matter from which point of view, the above embodiments of the present application should be regarded as exemplary and non-restrictive, and the scope of the present application is defined by the attached claims rather than the above description, and therefore it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present application.
