[0002] When assembling an air conditioner, the motor bracket of the air conditioner needs to be mounted on the chassis of the air conditioner. In order to reduce the labor intensity of the assemblers, in some technologies, an industrial robot is used to carry the motor bracket and accurately install the motor bracket on the air conditioner chassis by the industrial robot.

[0003] However, there are many types of air conditioners, and there are significant differences in the positions of the installation slots on the chassis of many different models of air conditioners. When installing the motor bracket on the chassis of different models of air conditioners, it is necessary to adjust the installation position or installation angle of the motor bracket so that the installation structure of the motor bracket matches the air conditioner chassis.

[0004] In order to adapt to the assembly work of different models of air conditioner chassis, it is necessary to manually identify the model of the air conditioner chassis. When the model of the air conditioner chassis changes, it is necessary to adjust the position or angle of the industrial robot, which not only increases the workload of the staff, but also reduces the assembly frequency of the industrial robot and the assembly efficiency of the air conditioner.

[0034] The present utility model will be further described below in conjunction with the accompanying drawings.

[0035] See Figure 1 As shown, in the figure, the first workpiece 101 is an air - conditioner chassis, and the second workpiece 102 is a motor bracket. Among them, an installation structure for assembling with the motor bracket is provided on the first workpiece 101. In order to meet the needs of different customers, there are a wide variety of air - conditioners, resulting in large differences in the positions of the installation structures in various models of the first workpiece 101.

[0036] For example, due to different internal matching components, it is necessary to adjust the extension direction of the installation structure, or due to the dimensional change of the first workpiece 101, the installation position of the installation structure is changed. In the past, in order to adapt to the change of the first workpiece model, it was necessary to set up a dedicated person to identify the model of the first workpiece and adjust the position of the assembly device according to the change of the model, so as to ensure that the assembly device can assemble the second workpiece with the first workpiece in place.

[0037] It can be understood that manual identification is limited by the state of the staff, and the recognition accuracy fluctuates greatly, with a high probability of error. Moreover, manually adjusting the position of the assembly device is also relatively time-consuming, greatly reducing the efficiency of workpiece assembly.

[0038] To solve the problem of low assembly efficiency when adapting to the assembly of different models of the first workpiece mentioned above, an embodiment of the present utility model provides a workpiece assembly device, which includes: a conveying device, an assembly device 400, and an identification device 500.

[0039] Among them, the conveying device is used to transport the first workpiece 101 and the second workpiece 102. In some implementation manners, the conveying device includes a first conveying mechanism 200 and a second conveying mechanism 300. Among them, the first conveying mechanism 200 is used to transport the first workpiece 101, and the second conveying mechanism 300 is used to transport the second workpiece 102. In other implementation manners, a single conveying mechanism can also be used to realize the synchronous transportation of the first workpiece 101 and the second workpiece 102.

[0040] The identification device 500 is arranged on one side of the first conveying mechanism 200, and the identification device can identify the model of the first workpiece 101.

[0041] The assembly device 400 is electrically connected to the identification device 500. The assembly device 400 can move the second workpiece 102 to the corresponding position on the first workpiece 101. Here, the corresponding position refers to the installation structure provided on the first workpiece 101, such as an installation groove, an installation protrusion, etc.

[0042] By first moving the second workpiece 102 to the corresponding position of the first workpiece 101, it is not necessary to stop the production line to adjust the position of the assembly device 400, thereby improving the efficiency of the assembly work.

[0043] In this application, the identification function of the identification device 500 is used to replace manual identification, and by electrically connecting the identification device 500 with the assembly device 400, the assembly device 400 can obtain the model type of the first workpiece 101. Compared with the prior art, it not only reduces the number of staff and labor costs, but also can improve the switching efficiency of the assembly program of the assembly device 400, which is beneficial to the improvement of the assembly efficiency.

[0044] It should be noted that the first workpiece 101 is not limited to the air conditioner chassis mentioned above. The first workpiece 101 can also be other components that need to be assembled. In addition, although the assembly device 400 is a multi-degree-of-freedom manipulator in the illustrated figure, in other implementation manners, the assembly device 400 is not limited to a multi-degree-of-freedom manipulator. The assembly device 400 can also be other types of assembly equipment, such as a crimping device driven by a telescopic cylinder or a plugging device that moves horizontally, etc.

[0045] In some implementation manners, the recognition device 500 includes a camera. The camera is located above the first conveying mechanism 200 and corresponds to the assembly position of the first workpiece. Here, the assembly position refers to the position of the structure in the first workpiece 101 that is used to cooperate with the second workpiece 102. That is, the position of the mounting groove or mounting protrusion in the first workpiece 101.

[0046] That is to say, in the present application, the recognition device 500 realizes the model recognition of the first workpiece 101 through image recognition technology. The image recognition technology is currently relatively mature. Among them, image recognition includes identification code recognition technologies such as barcodes and two-dimensional codes, and also includes object recognition technologies such as face recognition and vehicle recognition.

[0047] The camera in the present application is mainly used to photograph the installation structure (installation groove, installation protrusion, etc.) of the first workpiece 101. The recognition device judges the model of the first workpiece 101 based on the comparison structure between the photographed image of the installation structure and the pre-stored image, and sends the analyzed model type to the assembly device 400. The assembly device 400 adjusts the assembly mode by using the model of the first workpiece 101.

[0048] In some cases, common foreign objects such as screws, paper scraps, and plastic bags may be attached to the installation structure of the first workpiece 101, or the installation structure may be severely deformed. Especially for the installation structure of the air conditioner chassis, an installation groove is often set on the air conditioner chassis as the installation structure, and some foreign objects are often accommodated in the installation groove, making the installation structure of the first workpiece 101 unable to meet the installation requirements of the second workpiece 102.

[0049] In view of this situation, in some implementation manners, the recognition device 500 is also electrically connected to an alarm device. By photographing the installation structure of the first workpiece 101 through the camera of the recognition device 500, not only can the position of the installation structure be analyzed to obtain the model of the first workpiece 101, but also it can be analyzed whether the installation structure meets the installation requirements by comparing the shape of the installation structure. When the installation structure does not meet the installation requirements, the alarm device issues an alarm to remind the staff to clean or repair the installation structure, so as to avoid forcibly installing the second workpiece 102 into an inappropriate first workpiece 101, causing damage to the second workpiece 102 or the first workpiece 101.

[0050] The warning signal emitted by the warning device can be one of a sound signal or an optoelectronic signal, or can simultaneously emit a sound signal and an optoelectronic signal.

[0051] It can be understood that in addition to photographing the installation structure of the first workpiece 101, the identification device 500 can also photograph other areas of the first workpiece 101 to detect whether other structures of the first workpiece 101 meet the installation requirements.

[0052] In other implementation manners, a label (a two-dimensional code label or a radio frequency label) can also be set on the first workpiece 101. The label of the first workpiece 101 is obtained by photographing the label through a camera, and then the information in the label is obtained by using the image recognition of the first processor, so as to complete the identification of the model of the first workpiece 101. Information such as a product number and a product model can be set in the label. The first processor directly obtains the corresponding product model by recognizing the information in the label, and transfers the model of the first workpiece 101 to the assembly device 400.

[0053] The above describes the identification of the model of the first workpiece 101 by the identification device 500 equipped with a camera. In other implementation manners, the model of the first workpiece 101 can also be identified based on other features of the first workpiece 101. For example, for products with large weight differences, the model of the first workpiece 101 can be measured by weighing. For products with large height differences, the model of the first workpiece 101 can be measured by using multiple groups of optoelectronic sensors with different heights. Of course, since image recognition has a wider range of applications and can be used for the identification of most products, it is preferred to use the identification device 500 equipped with a camera to identify the model of the first workpiece 101.

[0054] See Figure 1 and Figure 2 As shown, in some implementation manners, the assembly device 400 is a six-degree-of-freedom robotic arm, and the identification device 500 is integrated at the execution end of the assembly device 400. Integrating the identification device 500 at the execution end of the assembly device 400 avoids the need to additionally set up a frame or other installation and identification structures, can reduce the floor space occupied by the identification device 500, and during the assembly process of the assembly device 400, the identification device 500 can move closer to the first workpiece 101 along with the movement of the execution end, so as to photograph the first workpiece 101 at a close distance, improve the photographing quality of the identification device 500, and improve the photographing accuracy. After the assembly is completed, the identification device 500 can move away from the first workpiece 101 along with the movement of the execution end, avoiding the identification device 500 from affecting the flow of the first workpiece 101 to the next work station.

[0055] That is to say, installing the recognition device 500 at the execution end of the six-degree-of-freedom robotic arm enables the recognition device 500 to approach or move away from the first workpiece 101, facilitating the recognition device 500 to capture the installation area of the first workpiece 101 and improving the shooting effect of the camera. Of course, a three-degree-of-freedom robotic arm can also be used, as long as it can, in addition to completing the installation of the second workpiece 102 (such as moving in the x direction for assembly), adjust the installation position (such as moving the second workpiece in the y direction or z direction to adjust the installation position).

[0056] It can be understood that, in order to ensure the shooting effect of the recognition device 500, the recognition device 500 can also be integrated with a fill light. Before the recognition device 500 takes a picture, the fill light can be turned on in advance to illuminate the first workpiece 101, so that the camera can capture a clearer image for the first processor to identify the model of the first workpiece 101.

[0057] It should be noted that when the assembly device 400 selects a six-degree-of-freedom robotic arm, after the assembly device 400 obtains the model of the first workpiece 101, the first processor of the recognition device 500 communicates with the second processor of the assembly device 400 and sends the model of the first workpiece 101 to the second processor of the assembly device 400. The second processor then controls each driving part of the assembly device 400 based on the corresponding assembly program, enabling the execution end of the six-degree-of-freedom robotic arm to adjust the second workpiece 102 to a suitable installation pose.

[0058] Among them, the first processor and the second processor can complete signal transmission through wired communication, and can also use wireless communication technologies such as Bluetooth and infrared to achieve signal transmission. Of course, the first processor and the second processor can also be integrated together, and the integrated processor can complete image recognition and manipulator control work uniformly. Or the first processor is communicatively connected to the electric control cabinet 800, and the electric control cabinet 800 is communicative with the second processor to achieve communication between the first processor and the second processor.

[0059] In the related art, in order to reduce the number of conveying devices, the first conveying mechanism 200 is not only used for the assembly of the first workpiece 101 and the second workpiece 102, but also performs other processes. For example, a second working station and a maintenance station are also provided on the first conveying mechanism 200. In some implementation manners, the second working station can be used for the copper tube welding of the air conditioner, and the maintenance station is used to detect whether the copper tube leaks. After detecting an abnormality at the maintenance station, the first workpiece 101 with the second workpiece 102 installed thereon is placed on the first conveying mechanism 200 for repair. It can be understood that since the second workpiece 102 has been installed on the first workpiece 101, when the first workpiece 101 is conveyed to the assembly station, it should be avoided to install the second workpiece 102 on the first workpiece 101 again.

[0060] To avoid assembly errors caused by repeated installation, in some implementation manners, the assembly device 400 is installed with a first detection device, and the first detection device can detect whether a second workpiece 102 is installed on the first workpiece 101 at the assembly station. The first detection device is electrically connected to the assembly device 400. Specifically, the first detection device can adopt a photoelectric sensor, and the photoelectric sensor is oriented towards the first workpiece 101 to detect whether there is a characteristic structure of the second workpiece 102. For example, in this application, the second workpiece 102 is a motor bracket installed on the air-conditioning chassis, as Figure 1 and Figure 3 shown, the motor bracket is provided with a horizontal mounting plate ( Figure 1 in), and the height difference between the mounting plate and the bottom plate of the air-conditioning chassis is relatively fixed. The first detection device can be used to detect whether there is a mounting plate of the motor bracket at the first height to determine whether the second workpiece 102 is installed on the first workpiece 101. In other implementation manners, a camera with image recognition function can also be directly used as the first detection device to determine whether the second workpiece 102 is assembled on the first workpiece 101 by means of photographing and recognition.

[0061] When the photoelectric sensor detects that the second workpiece 102 is installed in the installation area, the assembly device 400 electrically connected to the first detection device stops assembling the second workpiece 102 to the first workpiece 101 to avoid repeated installation work. When the first detection device does not detect that the second workpiece 102 is installed at the installation structure, the assembly device 400 electrically connected to the first detection device normally assembles the second workpiece 102 to the first workpiece 101.

[0062] Compared with manually identifying whether the second workpiece 102 is installed on the first workpiece 101 and manually controlling whether to install the second workpiece 102 on the first workpiece 101, the detection by the first detection device has higher efficiency and reduces the labor cost.

[0063] It can be understood that, in some implementation manners, the first detection device is not limited to a photoelectric sensor, and an ultrasonic sensor or an electromagnetic sensor can also be adopted. It only needs to control the detection area of the first detection device to face the installation structure of the first workpiece 101.

[0064] See Figure 2 shown, in some implementation manners, the first transfer mechanism 200 is installed with a first positioning component 600, and the first positioning component 600 is used to position the first workpiece 101 to the assembly station of the first transfer mechanism 200.

[0065] The positioning of the first workpiece 101 can be achieved through the first positioning component 600, so as to improve the assembly accuracy of the second workpiece 102 and the first workpiece 101 when the assembly device 400 assembles the second workpiece 102 with the first workpiece 101, and avoid the reduction of assembly accuracy caused by the position deviation of the first workpiece 101.

[0066] Figure 6 In this case, the first positioning component 600 positions the first workpiece 101 by the push of the first positioning member 610. In other implementation manners, there are various positioning methods, not limited to the push positioning method. The positioning by a positioning pin or the positioning of the first workpiece 101 by a positioning track can also be adopted.

[0067] In some implementation manners, the first positioning component 600 includes a first positioning member 610 and a second positioning member 620. The first positioning member 610 and the second positioning member 620 are arranged at intervals along a first direction on opposite sides of the assembly station. The first direction is perpendicular to the conveying direction of the first conveying mechanism 200. At least one of the first positioning member 610 and the second positioning member 620 can move along the first direction.

[0068] Figure 6 In this case, the first positioning member 610 is connected with a first driving member 630. The first driving member 630 can drive the first positioning member 610 to move along the first direction, so as to adjust the distance between the first positioning member 610 and the second positioning member 620. When the first workpiece 101 is transported to the first positioning member 610, the first positioning member 610 moves close to the second positioning member 620 along the first direction under the drive of the first driving member 630, so as to clamp and position the first workpiece 101 between the first positioning member 610 and the second positioning member 620, and avoid the first workpiece 101 deviating from the installation position in the first direction.

[0069] Among them, in some implementation manners, the first driving member 630 is electrically connected with a second detection device. The second detection device is arranged on the first conveying mechanism 200 and is used to detect whether the first workpiece 101 is transported between the first positioning member 610 and the second positioning member 620. When the second detection device detects that there is a first workpiece 101 between the first positioning member 610 and the second positioning member 620, the second detection device sends a positioning signal to the first driving member 630, so that the first driving member 630 drives the first positioning member 610 to move close to the second positioning member 620 along the first direction, and clamps and positions the first workpiece 101 between the first positioning member 610 and the second positioning member 620.

[0070] It can be understood that the first driving member 630 can also be connected to the second positioning member 620, so that the second positioning member 620 can move along the first direction, realizing the positioning of the first workpiece 101 by the first positioning member 610 and the second positioning member 620. Alternatively, each of the first positioning member 610 and the second positioning member 620 is connected to a first driving member 630, and the first positioning member 610 and the second positioning member 620 are controlled synchronously to move closer to or away from each other, realizing the positioning of the first workpiece 101.

[0071] Among them, the first driving member 630 can be a cylinder, and the first driving member 630 drives the first positioning member 610 to move along the first direction through the telescopic movement of the cylinder. Of course, the first driving member 630 can also be a driving component such as an electric cylinder or a lead screw.

[0072] As Figure 6 shown, the first positioning member 610 is connected with a plurality of first driving members 630 to increase the driving force on the first positioning member 610.

[0073] See Figure 6 shown, in some implementation manners, the first positioning member 610 includes a first positioning portion 611, and one end of the first positioning portion 611 close to the feeding port of the first conveying mechanism 200 is connected with a first guiding portion 612;

[0074] Among them, the first positioning portion 611 is substantially parallel to the second positioning member 620, and the first guiding portion 612 is inclined relative to the first positioning portion 611 in a direction away from the second positioning member 620.

[0075] That is to say, a positioning groove structure is formed between the first positioning portion 611 and the second positioning member 620, and the first guiding portion 612 inclined relative to the first positioning portion 611 can guide the first positioning member 610 on the first conveying mechanism 200 to move towards the first positioning portion 611.

[0076] See Figure 6 shown, the connection between the first positioning portion 611 and the first guiding portion 612 is transitioned by a fillet, so that the first workpiece 101 moves more smoothly from the first guiding portion 612 to the first positioning portion 611, avoiding being scratched by the sharp corners at the connection between the first positioning portion 611 and the first guiding portion 612.

[0077] In some implementations, in order to prevent the first positioning member 610 and the second positioning member 620 from scratching the first workpiece 101, the outer contours of the first positioning member 610 and the second positioning member 620 may be polished to reduce the surface burrs of the first positioning member 610 and the second positioning member 620, thereby preventing the surface burrs from scratching the first workpiece 101. By polishing the outer contours of the first positioning member 610 and the second positioning member 620, the friction coefficient of the outer surfaces of the first positioning member 610 and the second positioning member 620 may be reduced, so that the first workpiece 101 moves more smoothly along the outer side of the first positioning member 610, thereby preventing the transmission speed of the first workpiece 101 from being affected during the positioning process.

[0078] See also Figure 5 As shown, the first conveying mechanism 200 includes a belt conveying mechanism, and the first positioning assembly 600 also includes a positioning stopper 640, which is arranged on a side of the assembly station away from the feeding port of the first conveying mechanism 200, and the positioning stopper 640 is connected to a second driving member. By arranging the positioning stopper 640 on the side of the assembly station away from the feeding port, the first workpiece 101 on the first conveying mechanism 200 can be stopped at the assembly station, so as to prevent the first workpiece 101 from passing through the assembly station as it is conveyed by the first conveying mechanism 200.

[0079] See also Figures 4 - 6 As shown, the second driving member is located below the positioning stopper 640, and the second driving member is used to drive the positioning stopper 640 to move up and down. When the second driving member lifts the positioning stopper 640 upward, the positioning stopper 640 rises to the top of the first conveying mechanism 200, and the first workpiece 101 can be blocked by the positioning stopper 640. When the second driving member drives the positioning stopper 640 to move downward, the positioning stopper 640 can be moved from the gap of the first conveying mechanism 200 to the bottom of the conveyor belt, and the positioning stopper 640 does not have a blocking effect on the first workpiece 101. The first workpiece 101 can be transferred out of the assembly station under the drive of the first conveying mechanism 200.

[0080] In other implementations, the second driving member may be arranged at the same height as the positioning stopper 640, and the horizontal extension and retraction of the second driving member may drive the horizontal movement of the positioning stopper 640, thereby switching the positioning stopper 640 between the blocking state and the releasing state.

[0081] That is to say, in the present application, the first positioning member 610 and the second positioning member 620 are used to position the first workpiece 101 in the first direction, and the positioning stopper 640 is used to position the first workpiece 101 in the conveying direction. Combining the first positioning member 610, the second positioning member 620 and the positioning stopper 640 can accurately position the first workpiece 101 at the assembly station, facilitating the assembly device 400 to assemble the second workpiece 102 with the first workpiece 101 and improving the assembly accuracy of the second workpiece 102.

[0082] In some implementation manners, the first conveying mechanism 200 is not limited to the belt conveying mechanism, and a hoisting mechanism or a guide rail structure can also be selected to implement the conveying work of the first workpiece 101. Compared with other conveying mechanisms, the belt conveying has the advantages of low cost and long conveying distance. Similarly, the second conveying mechanism 300 is not limited to the belt conveying mechanism shown in the figure, and the second conveying mechanism 300 can also select a hoisting mechanism or a guide rail mechanism to implement the conveying work of the second workpiece 102.

[0083] Regarding the specific positioning scheme of the first positioning assembly 600, in some implementation manners, a third detection device is provided on one side of the first positioning member 610 close to the feeding port of the first conveying mechanism 200. When the third detection device detects the existence of the first workpiece 101, the first positioning member 610 is driven by the first driving device to reset, so that the gap between the first positioning member 610 and the second positioning member 620 reaches the maximum, facilitating the first workpiece 101 to be conveyed between the first positioning member 610 and the second positioning member 620.

[0084] A fourth detection device is also provided at the connection between the positioning stopper 640 and the first positioning member 610. When the fourth detection device detects the first workpiece 101, it indicates that the first workpiece 101 is about to be removed from the assembly station. The first workpiece 101 is moved in the first direction by controlling the first driving member 630 to achieve the positioning of the first workpiece 101 in the first direction. And by controlling the second driving member, the positioning stopper 640 is used to block the second workpiece 102 in the assembly station. In some implementation manners, the third detection device and the fourth detection device can select photoelectric sensors, or ultrasonic sensors or electromagnetic sensors.

[0085] In some implementations, both the first three-detection device and the assembly device 400 are electrically connected to the first conveyor mechanism 200. When the third-detection device detects the second workpiece 102, the electric control cabinet 800 controls the first conveyor mechanism 200 to stop conveying, so as to prevent the subsequent second workpiece 102 from being transported to the assembly station. Meanwhile, the assembly device 400 is started, and the execution end of the assembly device 400 moves to the assembly station, and the first detection device is used to identify whether the second workpiece 102 is installed on the first workpiece 101 at the assembly station. If the second workpiece 102 is installed on the first workpiece 101, it indicates that the first workpiece 101 located at the assembly station at this time is a repaired machine, and there is no need for the assembly device 400 to carry out the assembly work. If the second workpiece 102 is not installed on the first workpiece 101 at the assembly station, the type of the first workpiece 101 is identified by the identification device 500, and the assembly device 400 clamps the second workpiece 102 on the second conveyor mechanism 300 to the corresponding position based on the type of the first workpiece 101, and assembles the second workpiece 102 with the first workpiece 101 by using the assembly device 400.

[0086] See Figure 1 and Figure 2 As shown, in some implementations, a second positioning assembly 700 is installed on the second conveyor mechanism 300, and the second positioning assembly 700 is used to position the second workpiece 102. Specifically, the second positioning assembly 700 includes a first positioning plate 710 and a second positioning plate 720, and the first positioning plate 710 and the second positioning plate 720 are arranged at intervals on opposite sides of the second conveyor mechanism 300. The first positioning plate 710 is electrically connected to a third driving member, and the second positioning plate 720 is electrically connected to a fourth driving member. By controlling the third driving member and the fourth driving member, the gap between the first positioning plate 710 and the second positioning plate 720 can be adjusted, so as to realize the clamping and positioning of the second workpiece 102 located on the second conveyor mechanism 300.

[0087] It can be understood that the second positioning assembly 700, the second conveyor mechanism 300 and the second conveyor mechanism 300 are all electrically connected to the electric control cabinet 800. A fifth detection device is also arranged at the second positioning assembly 700, and the fifth detection device is used to detect whether the second workpiece 102 moves to the third station, where the third station refers to the area between the first positioning plate 710 and the second positioning plate 720. When the fifth detection device detects that the second workpiece 102 moves to the third station, the second conveyor mechanism 300 stops conveying, and the second positioning assembly 700 works to position the second workpiece 102.

[0088] After the assembly device 400 completes the assembly of the previous second workpiece 102, the two positioning clamping plates of the second positioning assembly 700 open, and the assembly device 400 clamps the second workpiece 102 located at the third station. As the assembly device 400 removes the second workpiece 102 from the second transfer mechanism 300, the second transfer mechanism 300 resumes its transfer operation and transports the next second workpiece 102 to the third station for positioning.

[0089] To clearly illustrate the working principle of the workpiece assembly equipment provided by the present application, reference can be made to Figure 7 the flow chart provided in

[0090] The second detection device provided on the first transfer mechanism 200 detects whether the first workpiece 101 is transferred to the assembly station. When the second detection device detects that the first workpiece 101 exists at the assembly station, the electric control cabinet 800 controls the assembly device 400 to grab the second workpiece 102 conveyed on the second transfer mechanism 300.

[0091] Then, the first detection device provided on the assembly device 400 detects whether the second workpiece 102 is assembled on the first workpiece 101 at the assembly station. When the first detection device detects that the second workpiece 102 is assembled on the first workpiece 101, it indicates that the first workpiece 101 is a repaired machine. The control assembly device 400 stops operating, and controls the second driving member 650 to move the positioning stopper 640 to release the first workpiece at the assembly station, and uses the first transfer mechanism 200 to transport the repaired machine out of the assembly station.

[0092] When the first detection device detects that the second workpiece 102 is not assembled on the first workpiece 101, it indicates that the first workpiece 101 is not a repaired machine. Then, the recognition device 500 continues to perform visual inspection. When the recognition device 500 detects that there is a foreign object at the installation structure for assembling the second workpiece 102 in the first workpiece 101, it is determined that the visual inspection is NG, and the alarm device is used to give an alarm to remind the staff to clean the foreign object at the installation structure. When the recognition device 500 detects that there is no foreign object at the installation structure, the recognition device 500 analyzes the model of the first workpiece 101 based on the offset of the installation structure and sends the model of the first workpiece 101 to the assembly device 400, so that the assembly device 400 switches to the corresponding assembly program and installs the second workpiece 102 grabbed by the assembly device 400 on the installation structure of the first workpiece 101.

[0093] By assembling the first workpiece 101 and the second workpiece 102 with the workpiece assembly equipment provided by the present application, it can adapt to the model change of the first workpiece 101, improve the assembly efficiency, and reduce the labor cost.
