Description

Technical Field

[0001] This invention relates to the field of electrical assembly technology, and in particular to a method, apparatus and equipment for quality prevention in electrical assembly. Background Technology

[0002] The quality control technology for electrical cabinet assembly determines the stability and safety of the product. During electrical cabinet assembly, bolt tightening, connector insertion, and seal installation are core quality control steps. However, currently, these all rely on manual visual inspection and operator self-checks, which easily leads to problems such as missing or loose bolts, loose connectors, and improperly installed seals. Furthermore, these problems are difficult to visually identify, easily causing subsequent malfunctions such as poor contact and seal failure. Existing quality control relies solely on operator self-inspection and quality inspector spot checks, which is not only inefficient and has a high rate of missed inspections, but also lacks mandatory, visually-based error-proofing measures embedded in the workflow. Therefore, the current quality control methods for electrical cabinet assembly suffer from low inspection efficiency. Summary of the Invention

[0003] This invention provides a method, apparatus, and equipment for quality prevention in electrical assembly, aiming to solve the problem of low inspection efficiency in existing electrical cabinet assembly quality control methods.

[0004] In a first aspect, embodiments of the present invention provide a quality error prevention method for electrical assembly, the method being applied to a quality error prevention terminal of a quality error prevention system, the method comprising:

[0005] After the fastener is tightened to the workpiece to be assembled to the specified torque, the automatic marking device is controlled to draw a continuous marking line at the connection between the fastener and the workpiece to be assembled.

[0006] After the marking line is drawn, the target plug is selected according to the insertion command, and the target plug is pushed into the target socket set on the workpiece to be assembled; wherein, the front end of the target socket is provided with a connector, and the connector is provided with a positioning confirmation window. When the target plug is successfully pushed into the target socket, the positioning confirmation window automatically switches from the first display state to the second display state.

[0007] The display status of the positioning confirmation window is detected; if the positioning confirmation window automatically switches from the first display status to the second display status, the corresponding workpiece to be assembled is transferred to the preset workstation rack; the sealing component installation operation is performed on the workpiece to be assembled on the preset workstation rack using a pressure-type installation fixture; after the sealing component installation is completed, the installation status of the sealing component on the workpiece to be assembled is verified using a go / no-go gauge.

[0008] If the installation status of the seal passes the verification and the marking lines are continuous and complete, then the workpiece to be assembled is deemed to be assembled successfully.

[0009] Secondly, embodiments of the present invention also provide a quality error prevention device for electrical assembly, the device being configured in a quality error prevention terminal of a quality error prevention system, the device comprising:

[0010] The drawing unit is used to control the automatic drawing device to draw a continuous marking line at the connection between the fastener and the workpiece after the fastener is tightened to the specified torque.

[0011] The insertion unit is used to select a target plug according to the insertion command after the marking line is drawn, and push the target plug into the target socket set on the workpiece to be assembled; wherein, the front end of the target socket is provided with a connector, and the connector is provided with a positioning confirmation window. When the target plug is successfully pushed into the target socket, the positioning confirmation window automatically switches from the first display state to the second display state.

[0012] The installation unit is used to detect the display status of the positioning confirmation window; if the positioning confirmation window is detected to automatically switch from the first display status to the second display status, the corresponding workpiece to be assembled is transferred to the preset workstation frame; the sealing installation operation is performed on the workpiece to be assembled on the preset workstation frame by a pressure installation fixture; after the sealing installation is completed, the installation status of the sealing on the workpiece to be assembled is verified by a go / no-go gauge.

[0013] The determination unit is used to determine that the assembly of the workpiece to be assembled is qualified if the installation status of the seal passes the verification and the marking line is continuous and complete.

[0014] Thirdly, embodiments of the present invention also provide an electronic device, which includes a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the method described in the first aspect above.

[0015] Fourthly, embodiments of the present invention also provide a computer-readable storage medium storing a computer program, the computer program including program instructions that, when executed by a processor, can implement the method described in the first aspect.

[0016] This invention provides a method, apparatus, and equipment for quality error prevention in electrical assembly. The method is applied to the quality error prevention terminal of a quality error prevention system. The method includes: after a fastener is tightened to a workpiece to be assembled to a specified torque, controlling an automatic marking device to draw a continuous marking line at the connection between the fastener and the workpiece; after the marking line is drawn, selecting a target plug according to a connection command, and pushing the target plug into a target socket provided on the workpiece; wherein, a connector is provided at the front end of the target socket, and a confirmation window is provided on the connector; when the target plug is successfully pushed into the target socket... When the positioning confirmation window automatically switches from the first display state to the second display state, the display state of the positioning confirmation window is detected. If the positioning confirmation window automatically switches from the first display state to the second display state, the corresponding workpiece to be assembled is transferred to the preset workstation rack. A pressure-type installation fixture is used to perform a sealing operation on the workpiece to be assembled on the preset workstation rack. After the sealing is installed, the installation state of the sealing on the workpiece to be assembled is verified by a go / no-go gauge. If the installation state of the sealing passes the verification and the marking line is continuous and complete, the workpiece to be assembled is deemed to be qualified.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0024] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes such combinations. Embodiments of the present invention provide a method, apparatus, and device for quality error prevention in electrical assembly. The method is applied to a quality error prevention terminal in a quality error prevention system. The present invention will now be described in detail through specific embodiments.

[0025] Figure 1 This is a flowchart illustrating a quality prevention method for electrical assembly provided in an embodiment of the present invention. Figure 1 As shown, the method includes the following steps S110-S140.

[0026] S110. After the fastener is tightened to the workpiece to be assembled with the specified torque, the automatic marking device is controlled to draw a continuous marking line at the connection between the fastener and the workpiece to be assembled.

[0027] In this embodiment, after the fasteners (such as bolts / nuts) are tightened to the workpiece to be assembled (such as an electrical cabinet) to a specified torque, the automatic marking device is controlled to draw a continuous marking line at the connection between the fasteners and the workpiece to be assembled. At the same time, the marking line drawing time, fastener position and line type color and other information are recorded to realize traceable management of the fastening status.

[0028] If the fastening condition of the fastener changes (such as loosening or displacement), the marking line will also break, become misaligned, or develop gaps. By drawing a continuous marking line at the connection between the fastener and the workpiece to be assembled, the fastening condition of the fastener can be visually verified.

[0029] The automatic marking device includes a trigger sensor, a positioning mechanism, and a marking assembly. In one embodiment, step S110 includes: detecting whether the fastener is tightened to the specified torque by the trigger sensor; if the fastener is tightened to the specified torque, then driving the marking assembly by the positioning mechanism to draw a continuous marking line at the connection between the fastener and the workpiece to be assembled based on a preset fastening marking operation standard.

[0030] In this embodiment, a trigger sensor is provided on the fastening tool. The trigger sensor is used to detect whether the fastener is tightened to the specified torque. When the fastening tool is used to tighten the fastener, the trigger sensor simultaneously completes torque detection. When it is detected that the fastener is tightened to the specified torque, a "tightened in place" trigger signal is sent to the quality error prevention terminal. After receiving the signal, the quality error prevention terminal proceeds to the next process, that is, the positioning mechanism drives the marking component to draw a continuous marking line at the connection between the fastener and the workpiece to be assembled based on the preset fastening marking operation standard. The fastening marking operation standard specifies the corresponding line type, line color and other unified operation standards for fasteners of different specifications.

[0031] In one embodiment, after step S110, the method further includes: during subsequent assembly, detecting the integrity status of the marking line through a visual inspection module; if the integrity status of the marking line is detected to be damaged, triggering an alarm device to prompt the operator to retighten the loose fasteners.

[0032] In this embodiment, during the subsequent assembly process, the integrity status of the marking line is detected by a visual inspection module (such as an industrial camera); if the integrity status of the marking line is detected to be damaged (such as the marking line being broken, misaligned, or having gaps), an alarm device is triggered to prompt the operator to retighten the loose fasteners.

[0033] S120. After the marking line is drawn, select the target plug according to the insertion command and push the target plug into the target socket set on the workpiece to be assembled; wherein, the front end of the target socket is provided with a connector, and the connector is provided with a positioning confirmation window. When the target plug is successfully pushed into the target socket, the positioning confirmation window automatically switches from the first display state to the second display state.

[0034] In this embodiment, based on the differences in circuits and functions, each plug and socket is affixed with a unique color-coded label. For example, the socket on the main circuit has a red color-coded label. After the marking line is drawn, the required plug's color-coded label is determined according to the insertion command, and the target plug is quickly selected based on the required plug's color-coded label. The target plug is pushed into the target socket set on the workpiece to be assembled. The target socket has a connector at its front end, and the connector has a positioning confirmation window. When the target plug is successfully pushed into the target socket, the positioning confirmation window automatically switches from a first display state (e.g., dark) to a second display state (e.g., bright). If the target plug is not successfully pushed into the target socket, or the target plug is only loosely inserted into the target socket, the positioning confirmation window remains in the first display state.

[0035] In one embodiment, after selecting a target plug according to the insertion command and pushing the target plug into a target socket disposed on the workpiece to be assembled, the method further includes: determining whether a first color-coded label on the target plug matches a second color-coded label on the target socket to obtain a label determination result; if the label determination result is yes, then unlocking the insertion mechanism of the target socket to allow the target plug to continue to be pushed into the target socket; if the label determination result is no, then locking the insertion mechanism of the target socket to prevent the target plug from continuing to be pushed into the target socket.

[0036] In this embodiment, it is determined whether the first color-coded label on the target plug matches the second color-coded label on the target socket to obtain a label determination result; if the color and code of the first color-coded label match the color and code of the second color-coded label one by one, it is determined that the first color-coded label and the second color-coded label are matched; if the label determination result is yes, the insertion mechanism of the target socket is unlocked, allowing the target plug to continue to be pushed into the target socket; if the label determination result is no, the insertion mechanism of the target socket is locked, preventing the target plug from continuing to be pushed into the target socket.

[0037] In one embodiment, after selecting the target plug according to the insertion command and pushing the target plug into the target socket set on the workpiece to be assembled, the method further includes: detecting the display state of the positioning confirmation window through an acoustic and optical sensor; if the positioning confirmation window is detected to automatically switch from a first display state to a second display state, then the corresponding workpiece to be assembled is transferred to a preset workstation rack; if the positioning confirmation window is not detected to automatically switch from the first display state to the second display state, then the method returns to the step of selecting the target plug according to the insertion command and pushing the target plug into the target socket set on the workpiece to be assembled.

[0038] In this embodiment, the display state of the positioning confirmation window is detected by an acoustic and optical sensor; if the display state of the positioning confirmation window is detected to be the second display state, the corresponding workpiece to be assembled is transferred to the preset workstation rack; if the positioning confirmation window is not detected to automatically switch from the first display state to the second display state, the process returns to the step of selecting the target plug according to the insertion command and pushing the target plug into the target socket set on the workpiece to be assembled.

[0039] S130. Detect the display status of the positioning confirmation window; if the positioning confirmation window automatically switches from the first display status to the second display status, then transfer the corresponding workpiece to be assembled to the preset workstation frame; perform a sealing installation operation on the workpiece to be assembled on the preset workstation frame using a pressure-type installation fixture; after the sealing installation is completed, verify the installation status of the sealing on the workpiece to be assembled using a go / no-go gauge.

[0040] In this embodiment, the display status of the arrival confirmation window is detected; if the arrival confirmation window is detected to automatically switch from the first display status to the second display status, the corresponding workpiece to be assembled is transferred to the preset workstation rack to realize the automated diversion of qualified workpieces.

[0041] A pressure-type installation fixture is used to install seals on the workpieces to be assembled on the preset workstation frame. The seal body is designed with inspection protrusions that extend beyond the installation surface. After the seal is installed, a pass-through tool is used to pass over the installation surface of the seal. If the tool successfully passes over the surface, it indicates that there may be omissions, excessively deep installation grooves, or excessive pressure, and the installation status of the seal is determined to have failed the verification. If the tool is stopped by the inspection protrusion of the seal during the pass-through process, the installation status of the seal is determined to have passed the verification.

[0042] The pressure-type installation fixture is equipped with a detection sensor. In one embodiment, the process of performing a sealing component installation operation on the workpiece to be assembled on the preset workstation frame using the pressure-type installation fixture includes: pressing the sealing component into a designated installation slot of the workpiece to be assembled using the pressure-type installation fixture; during the pressing process, collecting pressing data in real time using the detection sensor, and determining whether the sealing component is properly pressed based on the pressing data; if the sealing component is properly pressed, removing the pressure-type installation fixture to complete the sealing component installation.

[0043] In this embodiment, the sealing element is pressed into the designated mounting slot of the workpiece to be assembled using the pressure-type installation fixture. During the pressing process, the detection sensor collects pressing data in real time, and determines whether the sealing element is pressed into place based on the pressing data. If the detection sensor is a pressure sensor, the pressing data is the pressing resistance. When the pressing resistance reaches a preset placement pressure threshold, the sealing element is determined to be pressed into place. If the detection sensor is a displacement sensor, the pressing data is the downward displacement of the pressure head of the pressure-type installation fixture. When the downward displacement reaches a preset placement displacement threshold, the sealing element is determined to be pressed into place. If the sealing element is pressed into place, the pressure-type installation fixture is removed, and the installation of the sealing element is completed.

[0044] In one embodiment, after the seal is installed, the installation status of the seal on the workpiece to be assembled is verified by a go / no-go gauge, including: after the seal is installed, the go / no-go gauge is slid across the installation surface of the seal for inspection; if the go / no-go gauge is blocked by the inspection protrusion of the seal during the sliding process, the installation status of the seal is determined to have passed the verification; if the go / no-go gauge passes smoothly along the installation surface without being blocked, the installation status of the seal is determined to have failed the verification, and an audible and visual alarm is triggered to indicate that the seal installation is abnormal.

[0045] In this embodiment, the seal body is designed with an inspection protrusion that extends beyond the mounting surface. After the seal is installed, the go / no-go gauge is used to scan along the mounting surface of the seal. If the go / no-go gauge is stopped by the inspection protrusion of the seal during the scan, it indicates that the inspection protrusion is normally raised and the seal is installed in place. At this time, the installation status of the seal is determined to have passed the verification. If the go / no-go gauge passes smoothly along the mounting surface without being stopped, it indicates that the inspection protrusion is missing or completely flattened, which may be due to missing parts, excessively deep mounting grooves, or excessive pressing. At this time, the installation status of the seal is determined to have failed the verification, and an audible and visual alarm is triggered to indicate that the seal installation is abnormal.

[0046] S140. If the installation status of the seal passes the verification and the marking line is continuous and complete, then the workpiece to be assembled is deemed to be qualified.

[0047] In this embodiment, if the installation status of the seal passes the verification and the marking line is continuous and complete, the workpiece to be assembled is deemed to be assembled successfully; if the installation status of the seal fails the verification and / or the integrity of the marking line is damaged, the workpiece to be assembled is deemed to be assembled unsuccessfully, and an audible and visual alarm is triggered to prompt the operator to promptly investigate and handle the abnormality.

[0048] In summary, this invention deeply integrates the three core quality control links of fastener tightening, connector insertion, and seal installation into the assembly process through visual and physical error prevention methods. The tightness of fasteners is visually verified by marking lines, the position confirmation window accurately determines whether the target plug and target socket are inserted in place, and the go / no-go gauge is used to ensure the seal installation is qualified. This forms a closed-loop quality control system from tightening to sealing, which significantly reduces assembly errors and missed inspection rates and significantly improves assembly inspection efficiency.

[0060] In some embodiments, the pressure-type installation fixture is equipped with a detection sensor. When the installation unit 703 performs the sealing installation operation on the workpiece to be assembled on the preset workstation frame using the pressure-type installation fixture, it is specifically used for:

[0063] After the seal is installed, the go / no-go gauge is slid across the installation surface of the seal for inspection. If the go / no-go gauge is stopped by the inspection protrusion of the seal during the sliding process, the installation status of the seal is deemed to have passed the inspection.

[0066] It should be noted that those skilled in the art can clearly understand that the specific implementation process of the above-mentioned quality prevention device for electrical assembly and each unit can be referred to the corresponding description in the foregoing method embodiments. For the sake of convenience and brevity, it will not be repeated here.

[0067] The aforementioned quality prevention device for electrical assembly can be implemented as a computer program, which can be used in, for example... Figure 3 It runs on the electronic device shown.

[0068] Please see Figure 3 , Figure 3 This is a schematic block diagram of an electronic device provided in an embodiment of the present invention. The electronic device 800 can be a terminal or a server. The terminal can be an electronic device with communication functions. The server can be a standalone server or a server cluster composed of multiple servers.

[0069] See Figure 3 The electronic device 800 includes a processor 802, a memory, and a network interface 805 connected via a system bus 801. The memory may include a non-volatile storage medium 803 and internal memory 804.

[0072] The internal memory 804 provides an environment for the execution of the computer program 8032 in the non-volatile storage medium 803. When the computer program 8032 is executed by the processor 802, the processor 802 can execute a quality prevention method for electrical assembly.

[0073] This network interface 805 is used for network communication with other devices. Those skilled in the art will understand that... Figure 3 The structure shown is merely a block diagram of a portion of the structure related to the present invention and does not constitute a limitation on the electronic device 800 to which the present invention is applied. The specific electronic device 800 may include more or fewer components than those shown in the figure, or combine certain components, or have different component arrangements.

[0074] The processor 802 is used to run a computer program 8032 stored in the memory to perform the following steps:

[0075] After the fasteners are tightened to the workpiece to be assembled to the specified torque, the automatic marking device draws a continuous marking line at the connection between the fasteners and the workpiece. After the marking line is drawn, a target plug is selected according to the insertion command, and the target plug is pushed into the target socket set on the workpiece. The target socket has a connector at its front end, and the connector has a positioning confirmation window. When the target plug is successfully pushed into the target socket, the positioning confirmation window automatically switches from a first display state to a second display state. The display state of the positioning confirmation window is detected. If the positioning confirmation window is detected to have automatically switched from the first display state to the second display state, the corresponding workpiece is transferred to a preset workstation. A pressure-type installation fixture is used to perform a sealing operation on the workpiece on the preset workstation. After the sealing is installed, the installation state of the sealing on the workpiece is verified by a go / no-go gauge. If the installation state of the sealing passes the verification and the marking line is continuous and complete, the workpiece is deemed to be assembled successfully.

[0076] In some embodiments, the automatic marking device includes a trigger sensor, a positioning mechanism, and a marking assembly. When the processor 802 controls the automatic marking device to draw a continuous marking line at the connection between the fastener and the workpiece after the fastener is tightened to a specified torque, the following steps are specifically implemented:

[0077] The trigger sensor detects whether the fastener is tightened to the specified torque. If the fastener is tightened to the specified torque, the positioning mechanism drives the marking assembly to draw a continuous marking line at the connection between the fastener and the workpiece to be assembled, based on the preset fastening marking operation standard.

[0078] In some embodiments, after the processor 802 performs the steps of selecting a target plug according to a mating command and pushing the target plug into a target socket disposed on the workpiece to be assembled, it further performs the following steps:

[0079] Determine whether the first color-coded label on the target plug matches the second color-coded label on the target socket to obtain a label determination result; if the label determination result is yes, unlock the insertion mechanism of the target socket to allow the target plug to continue to be pushed into the target socket; if the label determination result is no, lock the insertion mechanism of the target socket to prevent the target plug from continuing to be pushed into the target socket.

[0080] In some embodiments, after the processor 802 performs the steps of selecting a target plug according to a mating command and pushing the target plug into a target socket disposed on the workpiece to be assembled, it further performs the following steps:

[0081] The display status of the positioning confirmation window is detected by an acoustic and optical sensor; if the positioning confirmation window automatically switches from the first display status to the second display status, the corresponding workpiece to be assembled is transferred to the preset workstation rack; if the positioning confirmation window does not automatically switch from the first display status to the second display status, the process returns to the step of selecting the target plug according to the insertion command and pushing the target plug into the target socket set on the workpiece to be assembled.

[0082] In some embodiments, the pressure-type installation fixture is equipped with a detection sensor. When the processor 802 performs the sealing installation operation on the workpiece to be assembled on the preset workstation frame using the pressure-type installation fixture, it specifically implements the following steps:

[0083] The pressure-type installation fixture presses the seal into the designated installation slot of the workpiece to be assembled; during the pressing process, the detection sensor collects pressing data in real time, and determines whether the seal is pressed into place based on the pressing data; if the seal is pressed into place, the pressure-type installation fixture is removed to complete the installation of the seal.

[0084] In some embodiments, when the processor 802 verifies the installation status of the seal on the workpiece to be assembled using a go / no-go gauge after the seal installation is completed, the specific steps are as follows:

[0085] After the seal is installed, the go / no-go gauge is slid across the installation surface of the seal for inspection. If the go / no-go gauge is stopped by the inspection protrusion of the seal during the sliding process, the installation status of the seal is deemed to have passed the inspection. If the go / no-go gauge passes smoothly along the installation surface without being stopped, the installation status of the seal is deemed to have failed the inspection, and an audible and visual alarm is triggered to indicate that the seal installation is abnormal.

[0086] In some embodiments, after implementing the step of controlling the automatic marking device to draw a continuous marking line at the connection between the fastener and the workpiece to be assembled, the processor 802 further implements the following steps:

[0087] During subsequent assembly, the integrity of the marking lines is detected by a vision inspection module; if the integrity of the marking lines is detected to be damaged, an alarm device is triggered to prompt the operator to retighten the loose fasteners.

[0088] It should be understood that, in this embodiment of the invention, the processor 802 may be a Central Processing Unit (CPU), or it may be other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor may be a microprocessor or any conventional processor.

[0089] It will be understood by those skilled in the art that all or part of the processes in the methods of the above embodiments can be implemented by a computer program instructing related hardware. The computer program includes program instructions and can be stored in a storage medium, which is a computer-readable storage medium. The program instructions are executed by at least one processor in the computer system to implement the process steps of the embodiments of the above methods.

[0090] Therefore, the present invention also provides a storage medium. This storage medium can be a computer-readable storage medium. The storage medium stores a computer program, wherein the computer program includes program instructions. When executed by a processor, the program instructions cause the processor to perform the following steps:

[0091] After the fasteners are tightened to the workpiece to be assembled to the specified torque, the automatic marking device draws a continuous marking line at the connection between the fasteners and the workpiece. After the marking line is drawn, a target plug is selected according to the insertion command, and the target plug is pushed into the target socket set on the workpiece. The target socket has a connector at its front end, and the connector has a positioning confirmation window. When the target plug is successfully pushed into the target socket, the positioning confirmation window automatically switches from a first display state to a second display state. The display state of the positioning confirmation window is detected. If the positioning confirmation window is detected to have automatically switched from the first display state to the second display state, the corresponding workpiece is transferred to a preset workstation. A pressure-type installation fixture is used to perform a sealing operation on the workpiece on the preset workstation. After the sealing is installed, the installation state of the sealing on the workpiece is verified by a go / no-go gauge. If the installation state of the sealing passes the verification and the marking line is continuous and complete, the workpiece is deemed to be assembled successfully.

[0092] In one embodiment, the automatic marking device includes a trigger sensor, a positioning mechanism, and a marking assembly. When the processor executes the program instructions to control the automatic marking device to draw a continuous marking line at the connection between the fastener and the workpiece after the fastener is tightened to a specified torque, the following steps are specifically implemented:

[0093] The trigger sensor detects whether the fastener is tightened to the specified torque. If the fastener is tightened to the specified torque, the positioning mechanism drives the marking assembly to draw a continuous marking line at the connection between the fastener and the workpiece to be assembled, based on the preset fastening marking operation standard.

[0094] In one embodiment, after the processor executes the program instructions to select a target plug according to the insertion command and push the target plug into the target socket provided on the workpiece to be assembled, it further performs the following steps:

[0095] Determine whether the first color-coded label on the target plug matches the second color-coded label on the target socket to obtain a label determination result; if the label determination result is yes, unlock the insertion mechanism of the target socket to allow the target plug to continue to be pushed into the target socket; if the label determination result is no, lock the insertion mechanism of the target socket to prevent the target plug from continuing to be pushed into the target socket.

[0096] In one embodiment, after the processor executes the program instructions to select a target plug according to the insertion command and push the target plug into the target socket provided on the workpiece to be assembled, it further performs the following steps:

[0097] The display status of the positioning confirmation window is detected by an acoustic and optical sensor; if the positioning confirmation window automatically switches from the first display status to the second display status, the corresponding workpiece to be assembled is transferred to the preset workstation rack; if the positioning confirmation window does not automatically switch from the first display status to the second display status, the process returns to the step of selecting the target plug according to the insertion command and pushing the target plug into the target socket set on the workpiece to be assembled.

[0098] In one embodiment, the pressure-type installation fixture is equipped with a detection sensor. When the processor executes the program instructions to perform the sealing installation operation on the workpiece to be assembled on the preset workstation frame using the pressure-type installation fixture, the following steps are specifically implemented:

[0099] The pressure-type installation fixture presses the seal into the designated installation slot of the workpiece to be assembled; during the pressing process, the detection sensor collects pressing data in real time, and determines whether the seal is pressed into place based on the pressing data; if the seal is pressed into place, the pressure-type installation fixture is removed to complete the installation of the seal.

[0100] In one embodiment, after the processor executes the program instructions to install the seal, when verifying the installation status of the seal on the workpiece to be assembled using a go / no-go gauge, the following steps are specifically implemented:

[0101] After the seal is installed, the go / no-go gauge is slid across the installation surface of the seal for inspection. If the go / no-go gauge is stopped by the inspection protrusion of the seal during the sliding process, the installation status of the seal is deemed to have passed the inspection. If the go / no-go gauge passes smoothly along the installation surface without being stopped, the installation status of the seal is deemed to have failed the inspection, and an audible and visual alarm is triggered to indicate that the seal installation is abnormal.

[0102] In one embodiment, after the processor executes the program instructions to control the automatic marking device to draw a continuous marking line at the connection between the fastener and the workpiece to be assembled, the processor further performs the following steps:

[0103] During subsequent assembly, the integrity of the marking lines is detected by a vision inspection module; if the integrity of the marking lines is detected to be damaged, an alarm device is triggered to prompt the operator to retighten the loose fasteners.
