Technical Field

[0001] The present application relates to the technical field of assembly equipment, and in particular to a workpiece assembly system. Background Art

[0002] The workpiece assembly system can automatically lock fasteners such as bolts and nuts onto the workpiece through a robot.

[0003] The workpiece assembly system usually includes a workpiece conveying device and a locking device. After the workpiece conveying device transports the workpiece to the predetermined workstation, the locking device's manipulator grabs the fastener and locks it to the workpiece.

[0004] Existing workpieces are usually placed directly on a conveying device, which has a poor positioning effect on the workpiece. Utility Model Content

[0005] The present application provides a workpiece assembly system for solving the problem that existing workpiece assembly systems have poor workpiece positioning effects.

[0006] To achieve the above objectives, this application adopts the following technical solutions:

[0007] An embodiment of the present application provides a workpiece assembly system, comprising an installation station, a positioning device, and a transport device. The installation station is used to place a first workpiece and position the first workpiece at a first preset position. The positioning device is used to restrain a second workpiece at a second preset position. The transport device is used to transport the second workpiece to the positioning device and further to transport the second workpiece at the second preset position to a third preset position on the first workpiece at the first preset position.

[0008] In the workpiece assembly system provided by the embodiments of the present application, the positioning device is used to constrain the second workpiece to a second preset position. In actual application, the positioning device can constrain the second workpiece to maintain the second workpiece in the predetermined position, thereby ensuring the positional accuracy of the second workpiece and the accuracy of its setting angle, thereby ensuring the assembly accuracy of the second workpiece when assembled to the first workpiece. The transport device can transport the second workpiece, which has been positioned and calibrated, to the assembly position on the first workpiece, thereby ensuring the assembly accuracy of the second workpiece to the first workpiece.

[0009] In some embodiments, the positioning device includes a positioning platform, a first positioning assembly, and a second positioning assembly. The first positioning assembly is configured to fix the position of the second workpiece along a first horizontal direction. The second positioning assembly is configured to fix the position of the second workpiece along a second horizontal direction. The projection of the first direction on the horizontal plane intersects the projection of the second direction on the horizontal plane.

[0010] According to the above technical means, the positioning platform can provide support for the second workpiece and limit the positional accuracy of the second workpiece in the height direction, so that the second workpiece is positioned at an accurate height. In the horizontal direction, the first positioning assembly and the second positioning assembly can respectively position the second workpiece from two different directions, thereby ensuring the horizontal positional accuracy of the second workpiece. The positioning device can limit the positional accuracy of the second workpiece in various directions, thereby ensuring that the second workpiece is accurately placed at the second preset position.

[0011] In some embodiments, the first positioning assembly includes a first positioning member, a second positioning member, and a first drive mechanism. The first positioning member is fixed to the positioning platform. The second positioning member is spaced apart from the first positioning member along a first direction, with a receiving space provided between the second positioning member and the first positioning member for receiving a second workpiece. The first drive mechanism is connected to the second positioning member and is configured to drive the second positioning member to move toward or away from the first positioning member.

[0012] According to the above technical means, as the second positioning member moves toward the first positioning member, the second positioning member can push the second workpiece located in the accommodating space, thereby correcting the position accuracy of the second workpiece along the first direction.

[0013] In some embodiments, the second positioning assembly includes a third positioning member, a fourth positioning member, and a second drive device. The third positioning member is fixed to the positioning platform. The fourth positioning member is spaced apart from the third positioning member along the second direction, and the fourth positioning member and the third positioning member are located on opposite sides of the accommodating space. The second drive device is connected to the fourth positioning member and is configured to drive the fourth positioning member to move toward or away from the third positioning member.

[0014] According to the above technical means, as the fourth positioning member moves toward the third positioning member, the fourth positioning member can push the second workpiece located in the accommodating space, thereby correcting the position accuracy of the second workpiece in the second direction.

[0015] In some embodiments, the positioning device further comprises a support block connected to the positioning platform, and configured to support the second workpiece so that a gap is formed between at least a portion of the second workpiece and the positioning platform.

[0016] According to the above technical means, when the transport device needs to transport the second workpiece located on the positioning platform, a part of the transport device can be inserted into the gap between the second workpiece and the positioning platform, thereby facilitating the transport device to transport the second workpiece.

[0017] In some embodiments, the second workpiece is provided with a mounting portion, and the second workpiece is connected to the first workpiece via the mounting portion. The positioning device further includes an image acquisition device. The image acquisition device is configured to capture an image of the mounting portion of the second workpiece when the second workpiece is in the second predetermined position.

[0018] According to the above technical means, in the actual application process, the controller can control the movement of the conveying device according to the image captured by the image acquisition device to ensure that the installation part can correspond to the corresponding connection part set on the first workpiece, thereby avoiding the error in the processing of the installation part affecting the connection between the second workpiece and the first workpiece.

[0019] In some embodiments, the workpiece assembly system further includes a loading station for placing a second workpiece, and a transport device for transporting the second workpiece located at the loading station to the positioning device.

[0020] According to the above technical means, the second workpiece can be stored on the loading station, and the transport device can transport the second workpiece from the loading station in sequence.

[0021] In some embodiments, the handling device includes a gripping device and a third drive device. The gripping device is configured to grip the second workpiece. The third drive device is connected to the gripping device. The third drive device is configured to move in three-dimensional space to drive the gripping device to move in the three-dimensional space.

[0022] According to the above technical means, the grasping device can grasp the second workpiece, and the third driving device can move the grasping device in three-dimensional space, thereby realizing the transportation of the second workpiece from the loading station to the positioning device.

[0023] In some embodiments, the grasping device includes a first grasping member, a second grasping member, and a fourth drive device. The second grasping member is arranged along the width direction of the second workpiece, and the second grasping member is spaced relative to the first grasping member. The fourth drive device is connected to the third drive device, the first grasping member, and the second grasping member. The fourth drive device is driven by the third drive device to move in a three-dimensional space, thereby driving the first grasping member and the second grasping member to move in the three-dimensional space. The fourth drive device is also used to drive the first grasping member and the second grasping member to move toward or away from each other.

[0024] According to the above technical means, along the width direction of the second workpiece, the first grasping member and the second grasping member can respectively grasp the opposite sides of the second workpiece, thereby stably grasping the second workpiece.

[0025] In some embodiments, the second workpiece is provided with a gripping perforation. The first gripping member includes a first limiting surface and a second limiting surface, the first limiting surface facing away from the second gripping member, and the second limiting surface intersecting the first limiting surface. The second gripping member includes a third limiting surface and a fourth limiting surface, the third limiting surface facing away from the first gripping member, and the fourth limiting surface intersecting the third limiting surface. The first limiting surface and the third limiting surface respectively contact the inner walls on opposite sides of the gripping perforation, and the second limiting surface and the fourth limiting surface both contact the back surface of the second workpiece.

[0026] According to the above technical means, since the first and second clamping members grasp the air conditioner motor bracket through the hollow portion in the middle of the air conditioner motor bracket, collisions between the first and second clamping members and adjacent air conditioner motor brackets can be avoided, and there is no need to set excessive spacing between the air conditioner motor brackets at the loading station.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments.

[0045] In the embodiments of this 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 this application should not be interpreted as being preferred or advantageous over other embodiments or designs.

[0046] The air conditioner motor bracket is a crucial component of the air conditioning system, primarily used to secure and support the air conditioner's motor. It ensures the motor's stability and safety during operation, playing a crucial role in reducing vibration, lowering noise, and improving the air conditioner's efficiency.

[0047] The air conditioner motor bracket is relatively large. During the automated assembly process, if the air conditioner motor bracket has a slight angular deviation, it will affect the positioning accuracy of the robot when assembling it on the air conditioner outdoor unit.

[0048] Based on this, the embodiment of the present application provides a workpiece assembly system, such as Figure 1 As shown, Figure 1This is one of the schematic diagrams illustrating the positional relationship between the workpiece assembly system 100, the first workpiece 200, and the second workpiece 300 provided in an embodiment of the present application. The workpiece assembly system 100 may include an installation station for placing the first workpiece 200 and positioning the first workpiece 200 in a first preset position. In actual application, the installation station provides a processing position for the first workpiece 200 to facilitate subsequent automated assembly of the first workpiece 200.

[0049] like Figure 1 As shown, the workpiece assembly system 100 may further include a positioning device 1 for limiting the second workpiece 300 to a second preset position. In actual use, the positioning device 1 can limit the second workpiece 300 so that the second workpiece 300 is in the predetermined position, thereby ensuring the positional accuracy of the second workpiece 300 and the accuracy of its setting angle, thereby ensuring the assembly accuracy of the second workpiece 300 when assembled to the first workpiece 200.

[0050] The positioning device 1 can ensure the position accuracy of the air-conditioning motor bracket, thereby ensuring that the air-conditioning motor bracket can be accurately installed at the installation position on the housing of the air-conditioning outdoor unit.

[0051] Continue to refer to Figure 1 The workpiece assembly system 100 may further include a transport device 3 for transporting the second workpiece 300 to the positioning device 1. Thus, the transport device 3 can automatically load the second workpiece 300. In actual use, the transport device 3 can transport the second workpiece 300 from the incoming material section to the positioning device 1, so that the positioning device 1 can confine the second workpiece 300 to the second preset position.

[0052] The transport device 3 is also used to transport the second workpiece 300 located at the second preset position to a third preset position on the first workpiece 200 located at the first preset position. In actual use, the third preset position may be the assembly position of the first workpiece 200 for assembling the second workpiece 300. In this way, the transport device 3 can transport the second workpiece 300, which has undergone positioning and calibration, to the assembly position on the first workpiece 200, thereby ensuring the assembly accuracy of the second workpiece 300 on the first workpiece 200.

[0053] In actual application, the first workpiece 200 may be the housing of an outdoor air conditioner, and the second workpiece 300 may be the motor bracket of an air conditioner. When assembling the motor bracket to the housing of the outdoor air conditioner, the transport device 3 first transports the motor bracket to the positioning device 1. The positioning device 1 restrains the motor bracket to a second preset position. The transport device 3 then transports the motor bracket to the installation position on the housing of the outdoor air conditioner.

[0054] In order to realize that the positioning device 1 can limit the second workpiece 300 to the second preset position, in some embodiments, such as Figure 2 As shown, Figure 2 This is a second schematic diagram of the positional relationship between the workpiece assembly system 100, the first workpiece 200, and the second workpiece 300 provided in an embodiment of the present application. The positioning device 1 may include a positioning platform 11, which is used to support the second workpiece 300. In this way, during the positioning process of the second workpiece 300, the positioning platform 11 can provide support for the second workpiece 300 and limit the position accuracy of the second workpiece 300 in the height direction, so that the second workpiece 300 is at an accurate height position.

[0055] Continue to refer to Figure 2 The positioning device 1 may further include a first positioning assembly 12 and a second positioning assembly 13. The first positioning assembly 12 is used to fix the position of the second workpiece 300 along a first horizontal direction X, and the second positioning assembly 13 is used to fix the position of the second workpiece along a second horizontal direction Y. The projection of the first direction X on the horizontal plane intersects the projection of the second direction Y on the horizontal plane. In this way, the first positioning assembly 12 and the second positioning assembly 13 can respectively position the second workpiece 300 from two different horizontal directions, thereby ensuring the horizontal position accuracy of the second workpiece 300.

[0056] In actual use, the positioning platform 11 can limit the positional accuracy of the second workpiece 300 in the vertical direction, while the first positioning assembly 12 and the second positioning assembly 13 can limit the positional accuracy of the second workpiece 300 in the horizontal direction. Therefore, in three-dimensional space, the positioning device 1 can limit the positional accuracy of the second workpiece 300 in all directions, thereby ensuring that the second workpiece 300 is accurately placed at the second preset position.

[0057] At the same time, the first positioning assembly 12 and the second positioning assembly 13 can push the second workpiece 300 in the process of limiting the second workpiece 300 in the horizontal plane, thereby adjusting the shape of the second workpiece 300 so that the second workpiece 300 is in a predetermined shape.

[0058] In some embodiments, as Figure 3 As shown, Figure 3 This is a partial schematic diagram of the positional relationship between the workpiece assembly system 100 and the second workpiece 300 provided in an embodiment of the present application. The first positioning assembly 12 may include a first positioning member 121, a second positioning member 122, and a first drive device 123. The first positioning member 121 is fixed to the positioning platform 11, and the second positioning member 122 is spaced apart from the first positioning member 121 along the first direction X. An accommodating space is provided between the second positioning member 122 and the first positioning member 121, and the accommodating space is used to accommodate the second workpiece.

[0059] During the process of positioning the second workpiece 300 , the second workpiece 300 may be placed in the accommodation space, and the accommodation space may provide a setting position for the second workpiece 300 .

[0060] The first driving device 123 is connected to the second positioning member 122 and is used to drive the second positioning member 122 to move toward or away from the first positioning member 121. In actual use, as the second positioning member 122 moves toward the first positioning member 121, the second positioning member 122 can push the second workpiece 300 located in the accommodating space, thereby correcting the position accuracy of the second workpiece 300 along the first direction X.

[0061] In some embodiments, as Figure 3 As shown, the second positioning assembly 13 may include a third positioning member 131, a fourth positioning member 132, and a second driving device 133. The third positioning member 131 is fixed to the positioning platform 11, and the fourth positioning member 132 is spaced apart from the third positioning member 131 along the second direction Y. The fourth positioning member 132 and the third positioning member 131 are located on opposite sides of the accommodating space.

[0062] In this way, when the second workpiece 300 is disposed in the accommodating space, the second workpiece 300 may be located between the third positioning member 131 and the fourth positioning member 132 .

[0063] The first driving device 123 is connected to the fourth positioning member 132 and is configured to drive the fourth positioning member 132 to move toward or away from the third positioning member 131. In actual use, as the fourth positioning member 132 moves toward the third positioning member 131, the fourth positioning member 132 can push the second workpiece 300 located within the accommodating space, thereby correcting the positional accuracy of the second workpiece 300 in the second direction Y.

[0064] For example, Figure 3 As shown, the first driving device 123 can be a first cylinder, and the second positioning member 122 is connected to the output end of the first cylinder and is slidably connected to the positioning platform 11. The output end of the first cylinder can drive the second positioning member 122 to move toward or away from the first positioning member 121.

[0065] Correspondingly, the second driving device 133 can be a second cylinder, the fourth positioning member 132 is connected to the output end of the second cylinder, and is slidingly connected to the positioning platform 11. The output end of the second cylinder can drive the fourth positioning member 132 to move toward or away from the third positioning member 131.

[0066] In order to facilitate the transport device 3 to transport the second workpiece 300, in some embodiments, as Figure 4 As shown, Figure 4This is one of the partial schematic diagrams of the positional relationship between the positioning device 1 and the second workpiece 300 provided in an embodiment of the present application. The positioning device 1 may further include a support block 14. The support block 14 is connected to the positioning platform 11 and is used to support the second workpiece 300 so that a gap is formed between at least a portion of the second workpiece 300 and the positioning platform 11.

[0067] In the actual application process, the transport device 3 ( Figure 3 ) When the second workpiece 300 located on the positioning platform 11 needs to be transported, a portion of the transport device 3 can be inserted into the gap between the second workpiece 300 and the positioning platform 11, thereby facilitating the transport device 3 to transport the second workpiece 200 ( Figure 2 ).

[0068] In some embodiments, as Figure 5 As shown, Figure 5 This is a partial schematic diagram of the positional relationship between the positioning device 1 and the second workpiece 300 provided in an embodiment of the present application. The second workpiece 300 may be provided with a mounting portion 310, and the second workpiece 300 is used to connect to the first workpiece 200 ( Figure 2 ).

[0069] The positioning device 1 may further include an image acquisition device 15 , which is configured to acquire an image of the mounting portion 310 of the second workpiece 300 when the second workpiece 300 is at the second preset position.

[0070] It is understood that in actual application, the workpiece assembly system 100 may further include a controller (not shown in the figure), which may be electrically connected to the image acquisition device 15 and the transport device 3. The controller is used to receive the image acquired by the image acquisition device 15 and control the transport device 3 according to the image acquired by the image acquisition device 15 ( Figure 3 ) so that the transport device 3 transports the second workpiece 300 to the first workpiece 200 ( Figure 2 ), the mounting portion 310 on the second workpiece 300 may correspond to a corresponding connection portion on the first workpiece 200.

[0071] Thus, in actual application, the controller can control the movement of the transport device 3 according to the image captured by the image acquisition device 15 to ensure that the mounting portion 310 can correspond to the corresponding connection portion set on the first workpiece 200, thereby avoiding the error in the processing of the mounting portion 310 affecting the second workpiece 300 and the first workpiece 200 ( Figure 2 ) connection.

[0072] For example, Figure 5As shown, the second workpiece 300 can be an air conditioner motor bracket, the mounting portion 310 can be a connecting hole, and the image acquisition device 15 is located on one side of the positioning platform 11 and is arranged opposite to the portion of the air conditioner motor bracket where the connecting hole is opened.

[0073] When the second workpiece 300 is restricted to the second preset position, the image acquisition device 15 can capture the portion of the motor bracket where the connection hole is opened, and the controller can detect the position and size of the connection hole based on the captured image and feed it back to the transport device 3 ( Figure 2 ) to correct the motion parameters of the transport device 3. In this way, when the transport device 3 transports the motor bracket to the third preset position on the air conditioner outdoor unit housing, the mounting portion 310 on the motor bracket can correspond to the corresponding connection portion provided on the air conditioner outdoor unit housing.

[0074] It is understood that there are many ways to connect the second workpiece 300 and the first workpiece 200. For example, Figure 5 As shown, when the mounting portion 310 is a connecting hole, the first workpiece 200 ( Figure 2 ) can also be provided with a hole. The workpiece assembly system 100 can also include a locking device that can capture a bolt, pass it through the connecting hole and a corresponding hole in the first workpiece 200, and connect a nut to the bolt. In this way, the first workpiece 200 and the second workpiece 300 can be connected together.

[0075] Alternatively, the locking device may be a welding assembly that can weld the mounting portion 310 to the corresponding connection positions of the first workpiece 200. In this way, the first workpiece 200 and the second workpiece 300 can also be connected together.

[0076] In some embodiments, the workpiece assembly system 100 further includes a loading station for placing a second workpiece 300. The handling device 3 is configured to transport the second workpiece 300 located at the loading station to the positioning device. Thus, the second workpiece 300 can be stored at the loading station, and the handling device 3 can sequentially transport the second workpiece 300 from the loading station.

[0077] like Figure 6 As shown, Figure 6 The workpiece assembly system 100 and the second workpiece 300 provided in the embodiment of the present application are partially schematically shown. The workpiece assembly system 100 may further include a loading device 10. The loading device 10 may be provided with a plurality of loading stations. The handling device 3 ( Figure 2 ) can grab the second workpiece 300 from multiple loading stations formed on the loading device 10 in sequence according to the settings.

[0078] The loading device 10 may include a storage rack 101, on which a plurality of second workpieces 300 may be sequentially arranged. The storage rack 101 may be evenly distributed with a plurality of engaging grooves 1011. The plurality of second workpieces 300 may be engaged in the engaging grooves 1011. Thus, the engaging grooves 1011 may respectively limit the position of the plurality of second workpieces 300, thereby ensuring the positional accuracy of the plurality of second workpieces 300 on the storage rack 101, thereby facilitating the handling device 3 to grasp the second workpieces 300 located on the storage rack 101.

[0079] For example, Figure 6 As shown, the second workpiece 300 can be an air conditioner motor bracket, and the two parallel frames of the air conditioner motor bracket can be clamped in two adjacent clamping grooves 1011. In this way, the storage rack 101 can provide a storage location for the air conditioner motor bracket. At the same time, when the transport device 3 ( Figure 2 ) When the air conditioner motor bracket needs to be transported, the frame of the air conditioner motor bracket only needs to be pulled out from the clamping slot 1011, and the transport device 3 ( Figure 2 ) facilitates removing the air conditioner motor bracket from the storage rack 101.

[0080] In order to realize the transport function of the transport device 3, in some embodiments, as Figure 7 As shown, Figure 7 This is a second schematic diagram of the partial structure of the workpiece assembly system 100 and the second workpiece 300 provided in an embodiment of the present application. The handling device 3 may include a gripping device 31 and a third drive device 32. The gripping device 31 is used to grip the second workpiece 300. The third drive device 32 is connected to the gripping device 31 and is used to move in three-dimensional space to drive the gripping device 31 to move in three-dimensional space.

[0081] In actual application, the gripping device 31 can grip the second workpiece 300 , and the third driving device 32 can move the gripping device 31 in three-dimensional space, thereby transporting the second workpiece 300 from the loading station to the positioning device 1 .

[0082] For example, Figure 7 As shown, the third drive device 32 can be a six-axis manipulator, and the movable end of the six-axis manipulator can move in three-dimensional space. It is understandable that the third drive device 32 can also be other forms of manipulators, as long as it can move in three-dimensional space.

[0083] In some embodiments, as Figure 8 As shown, Figure 8This is a third schematic diagram of the partial structure of the workpiece assembly system 100 and the second workpiece 300 provided in an embodiment of the present application. The gripping device 31 may include a first gripping member 311, a second gripping member 312, and a fourth drive device 313. The first gripping member 311 and the second gripping member 312 are spaced apart from each other along the width direction of the second workpiece 300. Thus, along the width direction of the second workpiece 300, the first gripping member 311 and the second gripping member 312 can respectively grip opposite sides of the second workpiece 300, thereby stably gripping the second workpiece 300.

[0084] The fourth drive mechanism 313 is connected to the third drive mechanism 32, the first gripping member 311, and the second gripping member 312, and is configured to move within a three-dimensional space under the drive of the third drive mechanism 32, thereby driving the first gripping member 311 and the second gripping member 312 to move within the three-dimensional space. In actual use, the third drive mechanism 32 can drive the fourth drive mechanism 313 to move within the three-dimensional space, thereby driving the first gripping member 311 and the second gripping member 312 to move synchronously within the three-dimensional space.

[0085] The fourth driving device 313 is further configured to drive the first grasping member 311 and the second grasping member 312 to move toward or away from each other.

[0086] In some embodiments, as Figure 8 As shown, the second workpiece 300 is provided with a gripping perforation. Figure 9 As shown, Figure 9 This is a partial structural diagram of the workpiece assembly system 100 provided in an embodiment of the present application. The first gripping member 311 includes a first limiting surface 3111 and a second limiting surface 3112. The first limiting surface 3111 faces away from the second gripping member 312, and the second limiting surface 3112 intersects with the first limiting surface 3111. The second gripping member 312 includes a third limiting surface 3121 and a fourth limiting surface 3122. The third limiting surface 3121 faces away from the first gripping member 311, and the fourth limiting surface 3122 intersects with the third limiting surface 3121.

[0087] The first limiting surface 3111 and the third limiting surface 3121 respectively contact the inner walls on opposite sides of the grasping through-hole, and the second limiting surface 3112 and the fourth limiting surface 3122 both contact the back surface of the second workpiece 300. In this way, when the second workpiece 300 is removed from the engaging groove 1011, the second limiting surface 3112 and the fourth limiting surface 3122 can drive the second workpiece 300 to move away from the engaging groove 1011, thereby ensuring that the grasping device 31 can stably remove the second workpiece 300 from the engaging groove 1011.

[0088] For example, Figure 8 as well as Figure 9 As shown, when the second workpiece 300 is an air conditioner motor bracket, the gripping perforation can be the hollow portion in the middle of the air conditioner motor bracket. The first limiting surface 3111 and the third limiting surface 3121 respectively abut against the side walls of the hollow portion in the middle of the air conditioner motor bracket. The friction between the first limiting surface 3111 and the third limiting surface 3121 and the side walls of the hollow portion in the middle of the air conditioner motor bracket can enable the first gripping member 311 and the second gripping member 312 to drive the air conditioner motor bracket to move in three-dimensional space.

[0089] The second limiting surface 3112 and the fourth limiting surface 3122 can abut against the back of the air-conditioning motor bracket, that is, the air-conditioning motor bracket toward the clamping groove 1011 ( Figure 6 When the first grabbing member 311 and the second grabbing member 312 are removing the frame of the air-conditioning motor bracket from the engaging slot 1011, the second limiting surface 3112 and the fourth limiting surface 3122 can act on the surface of the air-conditioning motor bracket facing the bottom of the engaging slot 1011, thereby stably removing the air-conditioning motor bracket from the engaging slot 1011.

[0090] It is understood that when the first and second gripping members 311, 312 grip the air conditioner motor bracket, they pass through the hollow portion in the middle of the air conditioner motor bracket to grip the air conditioner motor bracket. This prevents collisions between the first and second gripping members 311, 312 and adjacent air conditioner motor brackets, and eliminates the need for excessive spacing between the air conditioner motor brackets at the loading station.

[0091] In some embodiments, as Figure 9 As shown, the gripping device 31 may further include two clamping and pushing members 314 and two clamping blocks 315. The two clamping blocks 315 are respectively disposed opposite the second limiting surface 3112 and the fourth limiting surface 3122. The clamping and pushing members 314 are connected to the clamping blocks 315 and are configured to drive the clamping blocks 315 to move so that the two clamping blocks 315 respectively abut against the side of the second workpiece 300 away from the second limiting surface 3112 and the fourth limiting surface 3122.

[0092] In this way, the two clamping blocks 315 and the second limiting surface 3112 and the fourth limiting surface 3122 can clamp the back and front sides of the second workpiece 300 respectively, which can improve the stability of the grasping device 31 in grasping the second workpiece 300.

[0093] In some embodiments, as Figure 10 As shown, Figure 10This is the third schematic diagram of the positional relationship between the workpiece assembly system 100, the first workpiece 200, and the second workpiece 300 provided in an embodiment of the present application. The workpiece assembly system 100 may further include a conveying device 4, which is used to transport the first workpiece 200 along a conveying path to transport the first workpiece 200 to a first predetermined position. In this way, automatic loading of the first workpiece 200 can be achieved, thereby improving the degree of automation of the workpiece assembly system 100.

[0094] In order to ensure that the first workpiece 200 can be accurately parked at the first predetermined position, in some embodiments, such as Figure 11 As shown, Figure 11 This is a fourth schematic diagram showing the positional relationship between the workpiece assembly system 100 and the first workpiece 200 and the second workpiece 300 provided in an embodiment of the present application. The workpiece assembly system 100 may further include a clamping device 5. The clamping device 5 includes a first clamping member 51, a second clamping member 52, and a fifth drive assembly 53. The first clamping member 51 and the second clamping member 52 are spaced apart along the conveying direction of the conveying device 4.

[0095] The fifth driving assembly 53 is connected to the first clamping member 51 and the second clamping member 52 , and is used to drive the first clamping member 51 and the second clamping member 52 to move toward or away from each other.

[0096] In actual use, after the second workpiece 300 is placed on the first workpiece 200, the first clamping member 51 and the second clamping member 52 move toward each other. Along the conveying path of the conveyor device 4, the first clamping member 51 and the second clamping member 52 can clamp the second workpiece 300 on opposite sides. In this way, the first clamping member 51 and the second clamping member 52 can improve the stability of the second workpiece 300, prevent the first workpiece 200 from shaking during the assembly process, and thus ensure the assembly accuracy of the first workpiece 200 and the second workpiece 300.

[0097] In order to prevent the first clamping member 51 and the second clamping member 52 from affecting the second workpiece 300 being transported to the first workpiece 200 by the transport device 3, in some embodiments, such as Figure 11 As shown, the clamping device 5 may further include a sixth drive assembly 54. The sixth drive assembly 54 is used to drive the first clamping member 51 and the second clamping member 52 to move up and down, so that the first clamping member 51 and the second clamping member 52 are arranged opposite to the second workpiece 300 or avoid the second workpiece 300 along the conveying direction of the conveying device 4.

[0098] During actual application, when the first workpiece 200 moves to the first predetermined position and needs to be assembled, the sixth drive component 54 can drive the first clamping member 51 and the second clamping member 52 to descend. At this time, the fifth drive component 53 drives the first clamping member 51 and the second clamping member 52 to move toward each other, and the first clamping member 51 and the second clamping member 52 can be clamped on both sides of the second workpiece 300 respectively.

[0099] After the second workpiece 300 is assembled onto the first workpiece 200, and the first workpiece 200 and the second workpiece 300 need to continue to be conveyed by the conveyor 4, the fifth drive assembly 53 drives the first clamping member 51 and the second clamping member 52 to move away from each other, so that the first clamping member 51 and the second clamping member 52 no longer clamp on both sides of the second workpiece 300. Then, the sixth drive assembly 54 drives the first clamping member 51 and the second clamping member 52 to rise, so that the first clamping member 51 and the second clamping member 52 clear of the second workpiece 300. At this time, the second workpiece 300 can be conveyed to the next workstation along with the first workpiece 200 by the conveyor 4.

[0100] In some embodiments, as Figure 11 As shown, the workpiece assembly system 100 may further include a mounting frame 6, along Figure 3 In the vertical direction, the mounting bracket 6 is at least partially located above the conveying device 4. The sixth drive assembly 54 is connected to the portion of the mounting assembly located above the conveying device 4. The fifth drive assembly 53 is connected to the movable end of the sixth drive assembly 54. The first clamping member 51 and the second clamping member 52 are connected to the movable end of the fifth drive assembly 53.

[0101] In this way, the mounting bracket 6 can provide a mounting position for the sixth driving assembly 54. The sixth driving assembly 54 can drive the fifth driving assembly 53 to move up and down, thereby driving the first clamping member 51 and the second clamping member 52 to move up and down.

[0102] For example, Figure 12 As shown, Figure 12 The fifth schematic diagram of the positional relationship between the workpiece assembly system 100, the first workpiece 200, and the second workpiece 300 provided in an embodiment of the present application shows that the sixth drive assembly 54 may include a drive motor 541, a guide slot 542, a transmission screw 543, a guide slider 544, and a connector 545. The drive motor 541 is disposed outside the guide slot 542, and the transmission screw 543 is rotatably connected to the guide slot 542. The transmission screw 543 is connected to the output end of the drive motor 541. In this way, the rotation of the drive motor 541 can drive the transmission screw 543 to rotate.

[0103] The guide slider 544 is slidably connected to the guide groove 542. A threaded through-hole is formed in the guide slider 544, and the drive screw 543 is disposed within the threaded through-hole and threadedly connected thereto. Thus, the rotation of the drive screw 543 drives the guide slider 544 along the direction in which the drive screw 543 extends. In actual use, the drive screw 543 can be positioned perpendicular to the ground, allowing the guide slider 544 to move up and down in a direction perpendicular to the ground.

[0104] A portion of the connector 545 is inserted into the guide slot 542 and connected to the guide slider 544. This allows the guide slider 544 to move along with the connector 545 during its lifting motion. The fifth drive assembly 53 can be connected to the portion of the connector 545 located outside the guide slot 542. This allows the fifth drive assembly 53 to move along with the connector 545 during its lifting motion.

[0105] Continue to refer to Figure 12 The fifth driving assembly 53 may be a clamping cylinder, and the first clamping member 51 and the second clamping member 52 may be connected to two output ends of the clamping cylinder, respectively. In this way, the first clamping member 51 and the second clamping member 52 may move toward or away from each other under the drive of the clamping cylinder.

[0106] The above is only a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or replacements within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
