Description

Technical Field

[0001] This invention relates to the field of processing control, and in particular to a control method, apparatus and electronic equipment for a product assembly line. Background Technology

[0002] In existing circular product assembly lines, product components, auxiliary materials, and other assembly materials continuously pass through various processing stations along a fixed circular route, where they are assembled and processed by workers at each station to produce the final product. Most existing circular product assembly lines use a double-speed chain as the transmission mechanism and tooling plates as the supporting medium for various assembly materials. After receiving a start signal, the control system begins operation, and the tooling plates move along the line under the traction of the double-speed chain. Each processing station on the assembly line is equipped with a tooling plate stopping mechanism and a tooling plate release button. When a tooling plate touches the stopping mechanism, the tooling plate transferred from the previous station is stopped at the current station, and the assembler at that station then performs the product assembly work on the tooling plate. After the assembly work at the current station is completed, the tooling plate release button is pressed, which releases the stopping mechanism from obstructing the tooling plate, allowing the tooling plate to pass smoothly through the current station and continue moving to the next station under the traction of the assembly line's conveyor mechanism.

[0003] However, different products often have different assembly and processing steps, and the number of processing stations required is not entirely the same. Therefore, it is usually necessary to customize a corresponding product assembly and processing line for each product, resulting in higher production costs. Summary of the Invention

[0004] The purpose of this invention is to provide a control method, device, and electronic equipment for a product assembly and processing production line, so that the same production line can flexibly cope with different application scenarios with different numbers of product assembly and processing steps, thereby effectively reducing the production cost of the product.

[0005] In a first aspect, the present invention provides a control method for a product assembly line, comprising: acquiring the working state of each processing station in the product assembly line; wherein the working state includes one of the following: an enabled state and a disabled state; after receiving a start signal of the product assembly line, sending an unlock command to the blocking mechanism of the processing station in the disabled state, so that the blocking mechanism of the processing station in the disabled state stops blocking the tooling plate; receiving a release request signal sent by a target processing station; wherein the target processing station represents any processing station in the enabled state; the release request signal is a signal sent after the release function of the target processing station is activated; sending an unlock command to the blocking mechanism of the target processing station based on the release request signal, so that the blocking mechanism of the target processing station releases the tooling plate blocked at the station; and controlling the product assembly line to stop operation after receiving a stop signal of the product assembly line.

[0006] In an optional implementation, the method further includes: receiving a tooling plate arrival signal sent by a proximity sensor at the target processing station, and recording the reception time of the tooling plate arrival signal; wherein the tooling plate arrival signal is used to indicate that the stopping mechanism of the target processing station stops the tooling plate at the current station; receiving a release request signal sent by the target processing station, and recording the reception time of the release request signal; calculating the reception time difference between the release request signal and the adjacent tooling plate arrival signals, so as to use the reception time difference as the single operation duration of the target processing station.

[0007] In an optional implementation, the method further includes: counting the number of operations and the duration of each operation at the target processing station within a specified time interval; calculating the average processing time of the target processing station within the specified time interval based on the number of operations and the duration of each operation; determining the processing station to be optimized based on the average processing time of all processing stations, so as to remind the staff to optimize and adjust the work content of the processing station to be optimized; wherein, the processing station to be optimized represents the processing station with the longest average processing time on the product assembly line.

[0008] In an optional implementation, the release function of the target processing station is activated when the release button located on the target processing station is pressed.

[0009] In an optional implementation, when the release button on the release control station is pressed, the release function of all processing stations on the product assembly line is activated.

[0010] In an optional implementation, the release control station includes one or more processing stations; when the release control station is multiple processing stations, the release function of all processing stations on the product assembly line is activated when the release button on all release control stations is pressed.

[0011] In an optional implementation, the method further includes: receiving information about the current product to be processed; and binding the single operation duration of the target processing station with the information about the current product to be processed.

[0012] Secondly, the present invention provides a control device for a product assembly line, comprising: an acquisition module for acquiring the working state of each processing station in the product assembly line; wherein the working state includes one of the following: an enabled state and a disabled state; a first sending module for sending an unlocking command to the blocking mechanism of a processing station in the disabled state after receiving a start signal of the product assembly line, so as to stop the blocking mechanism of the processing station in the disabled state from blocking the tooling plate; a first receiving module for receiving a release request signal sent by a target processing station; wherein the target processing station represents any processing station in the enabled state; the release request signal is a signal sent after the release function of the target processing station is activated; a second sending module for sending an unlocking command to the blocking mechanism of the target processing station based on the release request signal, so as to release the tooling plate blocked at the station by the blocking mechanism of the target processing station; and a control module for controlling the product assembly line to stop operation after receiving a stop signal of the product assembly line.

[0013] Thirdly, the present invention provides an electronic device, including a memory and a processor, wherein the memory stores a computer program that can run on the processor, and the processor executes the computer program to implement the steps of the control method for the product assembly and processing production line described in any of the foregoing embodiments.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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 embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0028] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] Example 1

[0030] Figure 1 This is a schematic diagram of the equipment structure of a circular production line (taking a 12-station production line as an example). Figure 2 This is a schematic diagram of a partial equipment structure of a circular assembly line. Circular product assembly lines mostly use a double-speed chain as the transmission mechanism and tooling plates as the supporting medium for various assembly materials. The line profile bracket is used to construct the line's external structure. Line support feet are used to support and fix the line. Lighting provides illumination to the workstations in low-light conditions. Sockets provide power to the electrical equipment at the workstations.

[0031] After receiving the start signal, the production line's control system begins operation. The double-speed chain motor drives the double-speed chain in continuous motion, and the tooling plate moves along the line under the traction of the chain. Each processing station on the production line is equipped with a tooling plate stopping mechanism and a tooling plate release button. When the tooling plate does not reach the stopping mechanism, the blocking cylinder in the stopping mechanism is in the raised state, and the blocking arm of the blocking cylinder is in the relaxed state. Figure 3 This is a schematic diagram illustrating the working principle of the tooling plate stopping mechanism, such as... Figure 3 As shown, when the tooling plate continues to move forward and touches the stop mechanism, the tooling plate transferred from the previous station is stopped at the current station, and the blocking arm of the blocking cylinder is locked. Then, the assembly personnel at this station perform assembly operations on the tooling plate.

[0032] After the assembly operation at the current workstation is completed and the tooling plate release button is pressed, the control system receives the tooling plate release signal and sends a command to the blocking cylinder to perform the release action, controlling the blocking cylinder to unlock. Subsequently, the blocking cylinder descends, releasing the blocking mechanism from obstructing the tooling plate, allowing the tooling plate at this workstation to pass smoothly through the current workstation and continue to move to the next workstation under the traction of the assembly line conveyor. When the tooling plate leaves the current workstation, the blocking cylinder returns to its initial state. When the control system receives a stop signal, the assembly line stops operating.

[0033] Figure 4 A flowchart of a control method for a product assembly line provided in an embodiment of the present invention is shown below. Figure 4 As shown, the method specifically includes the following steps:

[0034] Step S102: Obtain the working status of each processing station in the product assembly line.

[0035] The working status includes one of the following: enabled or disabled.

[0036] The control method provided in this invention is applied to the control system of a product assembly line. This method is not only applicable to the circular assembly line described above, but also to other types of assembly lines with multiple processing stations. In the prior art, different products require customized product assembly lines due to the varying number of assembly and processing steps, leading to higher production costs, resource waste, and large floor space requirements.

[0037] In this embodiment of the invention, to enable the product assembly line to adapt well to the needs of flexible manufacturing scenarios, before the product assembly line is started, operators are allowed to configure the working status of each processing station in the product assembly line through the control system. That is, operators can flexibly enable and disable each processing station on the line. If the product requires many processing steps, multiple processing stations are enabled; if the product requires few processing steps, a few processing stations are enabled, and the remaining stations are disabled. This allows the same product assembly line to be applicable to the processing flow of different products, thereby solving the technical problems mentioned above.

[0038] Step S104: After receiving the start signal of the product assembly line, an unlock command is sent to the stop mechanism of the processing station in the stopped state, so that the stop mechanism of the processing station in the stopped state stops blocking the tooling plate.

[0039] After the workers configure the working status of all processing stations on the product assembly line, pressing the "start" button sends a start signal to the control system. Upon receiving the start signal, the control system sends an unlock command to the stop mechanism of the inactive processing station, keeping the blocking cylinder at that station in a lowered state. This prevents the stop mechanism at the inactive station from blocking the tooling plate. In other words, when the tooling plate reaches an inactive processing station, it will not stop moving forward due to being blocked by the stop mechanism at that station, but will instead move directly to the next station.

[0040] Step S106: Receive the release request signal sent by the target processing station.

[0041] The target processing station refers to any processing station that is in an active state; the release request signal is the signal sent after the release function of the target processing station is activated.

[0042] For a target processing station that is in the active state, its blocking mechanism is locked, and the blocking cylinder remains in the raised position, blocking each tooling plate passing through this station. Once the tooling plate is blocked at the current station, the assembly personnel at this station can perform assembly operations on the tooling plate. Generally, when the assembly operation at the current station is completed, the release function of the target processing station will be activated to send a release request signal to the control system of the production line. This embodiment of the invention does not specifically limit the method of activating the release function of the target processing station. Users can set it according to actual needs. For example, it can be activated when the tooling plate release button of the target processing station is pressed, or the assembly status of the product at the current processing station can be identified by machine vision, and the release function of the station can be automatically activated when the assembly status is consistent with the preset status.

[0043] Step S108: Based on the release request signal, send an unlocking command to the blocking mechanism of the target processing station so that the blocking mechanism of the target processing station releases the tooling plate blocked at the station.

[0044] When the control system receives a release request signal from the target processing station, it immediately sends an unlocking command to the stop mechanism of the target processing station to control the blocking cylinder to descend, thereby allowing the tooling plate that was stopped at the target processing station to be released.

[0045] Step S110: After receiving the stop signal from the product assembly line, control the product assembly line to stop running.

[0046] After product assembly is completed, the staff can send a stop signal to the control system by pressing the "stop" button on the product assembly line. Upon receiving the stop signal, the control system will immediately stop the product assembly line.

[0047] like Figure 5 As shown, taking a circular assembly line with 12 stations as an example, if each round of assembly requires 12 assembly steps, then the tooling plate will be stopped once each time it moves to a station. That is, the working status of all 12 processing stations should be set to the enabled state.

[0048] If a circular assembly line with 12 workstations needs to assemble a different product, the number of assembly steps will also be updated when the product is changed. Figure 5If "Station 3" is not in use, the operator can disable it before assembly begins by clicking the "Disable Station 3" button on the station deactivation settings page via touchscreen, desktop configuration software, or web-based system interface. Upon receiving the "Disable Station 3" signal, the control system sends an unlock command to the station's blocking mechanism, causing the blocking cylinder at that station to descend. Subsequently, as... Figure 6 As shown, when the tooling plate at "station 2" moves clockwise on the production line past "station 3", it can pass through "station 3" smoothly without being blocked by the stopping mechanism at "station 3". Only when the tooling plate continues to move to "station 4" will it be stopped again by the stopping mechanism at "station 4".

[0049] If it is necessary to deactivate multiple processing stations simultaneously, this requirement can also be met using the aforementioned operating method. For example, if stations "3", "7", and "8" are temporarily not in use, the operator can deactivate them sequentially by clicking the deactivation button on the station deactivation function settings page before the assembly work begins, through human-computer interaction methods such as touch screens, desktop configuration software, and web-based system pages. Subsequently, when the tooling plates on the production line move clockwise past stations "3", "7", and "8", they can pass through these three stations smoothly without being obstructed by the stopping mechanisms at these stations.

[0050] According to the product assembly line control method provided in the embodiments of the present invention, the operator can freely deactivate any processing station according to the actual product assembly and processing needs. The flexible activation and deactivation settings of each processing station on the product assembly line enable the same production line to flexibly cope with application scenarios with different numbers of product assembly and processing steps, thereby effectively reducing the production cost of the product.

[0051] In an optional implementation, the method of the present invention further includes the following steps:

[0052] Step S201: Receive the tooling plate arrival signal sent by the proximity sensor on the target processing station, and record the reception time of the tooling plate arrival signal.

[0053] The tooling plate arrival signal is used to indicate that the stop mechanism of the target processing station stops the tooling plate at the current station.

[0054] Step S202: Receive the release request signal sent by the target processing station and record the reception time of the release request signal.

[0055] Step S203: Calculate the reception time difference between the release request signal and the adjacent tooling plate arrival signal, and use the reception time difference as the single operation time of the target processing station.

[0056] Specifically, to assist in the analysis of the product processing process, such as Figure 7 As shown, in this embodiment of the invention, a corresponding proximity sensor is added to each processing station of the product assembly line. Based on the content described in the above method steps, the working principle of the single operation time statistics for each processing station is as follows:

[0057] Each processing station on the production line is equipped with a tooling plate stopping mechanism, a proximity sensor, and a tooling plate release button. When a tooling plate from the previous station moves to this station, the stopping mechanism stops the tooling plate at the current station, while the proximity sensor can detect that the tooling plate is in place in a non-contact manner and send a tooling plate arrival signal to the line control system.

[0058] Once the current assembly operation at the target machining station is completed, the operator can press the tooling plate release button at this station. At this time, the target machining station sends a release request signal to the control system. After the control system responds, it will send an unlock command to the stop mechanism of the target machining station, so that the stop mechanism of the target machining station releases the tooling plate that is stopped at the station. Then the tooling plate can be moved sequentially to the next station, where the operators of the corresponding station will perform the subsequent assembly operations.

[0059] The control system uses the time it receives the tooling plate arrival signal as the start time of the current assembly operation at this station, and the time it receives the release request signal at this station (i.e., the time the tooling plate release button is pressed) as the end time of the current assembly operation at this station. The difference between the two times is the total assembly time for this station. This process continues to calculate the single operation time for each processing station, enabling automatic calculation of station operation time.

[0060] Optionally, the control system in this embodiment of the invention can collect and record data generated during the assembly and processing process in real time, analyze the data, and then provide production improvement suggestions to the staff based on the actual production data to assist the manufacturer in lean production.

[0061] In an optional implementation, the method of the present invention further includes the following:

[0062] First, receive information about the product to be processed; then, bind the single operation duration of the target processing station with the information about the product to be processed.

[0063] Specifically, before product assembly and processing, staff can choose to select / register the information of the product to be processed within the system through human-computer interaction methods such as touch screens, desktop configuration software, and web-based system pages. In other words, they send the information of the product to be processed to the control system. Products already registered in the system can be selected directly; for unregistered products, product information must be registered in the system before selection.

[0064] Next, during the processing, the control system can bind the single operation time of each activated processing station with the information of the product to be processed, for use in subsequent lean production analysis.

[0065] In an optional implementation, after calculating the single operation time of the target processing station, the method of the present invention further includes the following steps:

[0066] Step S301: Count the number of operations at the target processing station and the duration of each operation within the specified time interval.

[0067] Step S302: Based on the number of jobs and the duration of each job, calculate the average duration of the target processing station within a specified time interval.

[0068] Step S303: Based on the average operation time of all processing stations, determine the processing stations to be optimized, so as to remind the staff to optimize and adjust the work content of the processing stations to be optimized.

[0069] Among them, the processing station to be optimized refers to the processing station with the longest average operation time on the product assembly line.

[0070] This invention does not specifically limit the specified time interval. Users can customize the setting, or the system can provide it automatically. If the user customizes the setting, that is, manually sets the start and end time of the data query, the staff can set a start and end time for the data query through human-computer interaction methods such as touch screen, desktop configuration software, and web system page. If the staff does not manually set the time interval for the data query, the system can automatically use weeks, months, quarters, etc. as the time interval for the data query.

[0071] The control system calculates the average single operation time of the target processing station within a specified time interval, based on the single operation duration and the number of operations within that time interval. That is, Average = Total / times; where Average represents the average single operation time of the target processing station within the specified time interval; Total represents the sum of all single operation durations of the target processing station within the specified time interval; and times represents the number of operations of the target processing station within the specified time interval.

[0072] Because workstations with shorter single-operation times must wait for workstations with longer single-operation times to complete before starting the next operation, making the single-operation times of all workstations similar or identical can reduce unnecessary pauses and waiting during assembly, helping to lower the overall waiting time for all workstations on the production line. Therefore, after determining the average operation time of all active processing workstations on the product assembly line, the workstations to be optimized are located by comparing their average operation times; that is, the workstations with the longest average operation times on the production line. This allows staff to be reminded to optimize and adjust the work content of the workstations to be optimized.

[0073] For example, after identifying the processing station to be optimized, the staff will evaluate and optimize the work content and workload of the station, adjust the work content, reduce the workload, or optimize the work efficiency of the station to achieve line balance, and ultimately make the average single operation time of each station on the line more consistent, so as to minimize the total waiting time of the entire line.

[0074] When the types of products to be assembled on the product assembly line change, staff can still receive lean production suggestions by reselecting / registering new product information. This intelligent lean production improvement suggestion generation function can be widely applied to the assembly and processing of different types of products.

[0075] The above text explained that the control system will only receive the release request signal from the target machining station after the release function of the target machining station is activated. Below, we will introduce several ways to activate the release function of the target machining station:

[0076] Method 1: When the release button set on the target processing station is pressed, the release function of the target processing station is activated.

[0077] Method 2: When the release button on the release control station is pressed, the release function of all processing stations on the product assembly line is activated.

[0078] In this embodiment of the invention, the release control station includes one or more processing stations.

[0079] When there are multiple processing stations for release control, the release function of all processing stations on the product assembly line is activated when the release button on all release control stations is pressed.

[0080] Based on the above, there are three tooling plate release control modes. The first mode is controlled by the release button of each processing station, which activates the release function of that station. In other words, the release buttons of different stations are independent and not linked to each other. Each station's release button only controls the release action of the tooling plate at that station. Only when the release button of a station is pressed does the control system receive the release request signal it sends, and then send an unlock command to the stop mechanism of that station, so that the tooling plate at that station is released to the next station.

[0081] The second method uses a designated release control station's (tooling plate) release button to activate the release function of all stations on the production line. Specifically, this control mode can be selected when an operator at any given station needs to control the release of tooling plates at all stations on the entire production line. In this case, the operator at that station can control the work rhythm of the entire product assembly line. In practical applications, the operator can arbitrarily select a station from all stations as the tooling plate release control station according to the product assembly work requirements. When the operator presses the release button at the release control station, the control system sends an unlock command to the stop mechanisms of all stations on the production line to release the tooling plates at all stations, including that station. At this time, the release buttons on other stations are invalid, and the assembly progress on the production line is controlled by the operator at this release control station.

[0082] The third method uses any X (2 ≤ X ≤ maximum number of production line stations) release control stations' (tooling plate) release buttons to activate the release function of all stations on the line. Specifically, this control mode can be selected when multiple station operators need to jointly control the release of tooling plates across the entire production line. In this mode, the operators at these stations can jointly control the workflow of the entire product assembly line. Only when all operators with tooling plate release control authority press the tooling plate release button will all tooling plates on the line be released simultaneously. At this time, the tooling plate release buttons on other non-release control stations are ineffective, and the assembly progress on the line is jointly controlled by the operators at these X release control stations.

[0083] In summary, the product assembly line control method provided by this invention enables flexible activation and deactivation settings for each workstation on the assembly line, allowing the same assembly line to flexibly handle application scenarios with varying numbers of assembly and processing steps for different products. Furthermore, while workers are performing product assembly operations, the control system automatically calculates the single-operation time of each workstation and analyzes the data, providing lean production improvement suggestions to workers. This method is widely applicable to the assembly and processing of different types of products, assisting workers in optimizing and adjusting key production management control points such as the work content, workload, and efficiency of each workstation to achieve line balance. Additionally, this invention also allows for the customization of tooling plate release control permissions for each workstation. Operators at the release control workstations can select the appropriate control mode according to the assembly and processing requirements of different products, enabling the tooling plate release buttons at different workstations to be interconnected, facilitating flexible multi-person collaboration and lean production.
