Description

Technical Field

[0001] This utility model relates to the field of welding power source technology, and in particular to a welding control system for beverage cans that can monitor energy in a single cycle. Background Technology

[0002] In the field of high-speed welding production of beverage cans, welding quality is directly related to the product's sealing performance and safety. The rational design of the welding control system's hardware structure is the core foundation for ensuring welding quality and production stability. As production line speeds increase to hundreds or even thousands of cans per minute, welding frequencies have reached the 1000Hz level, and the formation time of a single weld point has entered the microsecond range. The structural design flaws of existing welding control systems are becoming increasingly prominent, becoming key factors restricting production efficiency and product quality.

[0003] In the energy monitoring stage, the existing control system's hardware module layout has significant shortcomings. Its monitoring unit often employs a separate sensor and computing module design. The signal transmission path between current and voltage sensors and the energy calculation processor lacks targeted optimization, and a trigger structure synchronized with the welding cycle is not included. This results in the inability to quickly transmit real-time signals collected by the sensors to the computing unit for immediate processing. This structural lag means that traditional systems can only rely on multi-cycle data aggregation to calculate the energy average, failing to accurately capture the energy of individual weld points. Consequently, it is difficult to locate defective weld points in a timely manner through hardware response, objectively leading to missed defect detection.

[0004] For high-current control scenarios, the existing high-frequency welding power supply design has shortcomings. To meet the high current output requirements of 7000A, the power conversion circuit of the power supply mostly adopts a conventional half-bridge or simplified full-bridge structure. The matching between the inverter tube group and the drive module is poor, and there is a lack of a precise adjustment structure for high current output. At the same time, some power supplies do not integrate a dedicated pre-charge circuit. The instantaneous inrush current of the filter capacitor bank at power-on can easily damage the contactor contacts, which not only affects the stability of the current output but also reduces the service life of the equipment. These structural deficiencies directly result in low current control resolution, making it difficult to achieve precise control, and easily leading to uneven solder joint quality in high-speed production.

[0005] In terms of thermal management, the existing system's heat dissipation structure design is ill-suited for high-frequency, high-power applications at the 155kVA level. Core power devices such as IGBT modules and transformers generate significant heat during operation, but existing cooling systems often employ single-pipe or air-cooled structures. The cooling channels do not conform to the surface contours of the core power devices, and the linkage control structure between the temperature controller and the water circulation loop is simplistic, failing to dynamically adjust heat dissipation efficiency based on device temperature. These design limitations result in heat not being dissipated promptly, leading to excessively high device temperatures. This not only causes fluctuations in soldering parameters but can also, in severe cases, cause component burnout, significantly impacting production continuity and stability.

[0006] The problems caused by the above-mentioned unreasonable hardware structure design have become a technical bottleneck that urgently needs to be solved through equipment structure optimization in the high-speed beverage can welding production. Utility Model Content

Based on these detailed descriptions, those skilled in the art will be able to clearly understand and implement this application. Without departing from the principles of this application, features from various embodiments can be combined to obtain new implementations, or certain features from some embodiments can be substituted to obtain other preferred implementations.

[0023] The following detailed description of a single-cycle energy monitoring control system for aluminum cans, based on specific embodiments, aims to clearly disclose the hardware structure and connection relationships of the implementation scheme. This embodiment only records the technical details related to the device structure and does not involve any method-related protection content.

[0024] like Figure 1 As shown, the single-cycle energy monitoring control system for beverage cans of this utility model mainly consists of a high-frequency welding power supply, a single-cycle energy monitoring module, a closed-loop feedback actuator, and a water-cooled temperature control subsystem.

[0025] The core functional modules include: High-frequency welding power supply: The core of the system's energy output, directly connected to the welding load, simultaneously outputting electrical signals to the single-cycle energy monitoring module, receiving parameter adjustment signals from the closed-loop feedback actuator, and forming a heat dissipation association with the water-cooled temperature control subsystem.

[0026] Single-cycle energy monitoring module: Receives electrical signals from high-frequency welding power source, transmits judgment results to closed-loop feedback actuator, and sends position identification signals to weld strengthening module.

[0027] Closed-loop feedback actuator: Connects the monitoring module and the power supply to achieve a hardware closed loop for parameter adjustment.

[0028] Water-cooled temperature control subsystem: directly acts on the core power devices of the high-frequency welding power supply to meet heat dissipation requirements.

[0029] The auxiliary function modules include: Solder joint strengthening module: Receives position signals from the monitoring module and sends enhanced energy control signals to the power supply.

[0030] Protection circuit group: connected in series with the high-frequency welding power supply to achieve safety protection during power transfer.

[0031] Each module is structurally connected to the circuitry via a hardware interface, forming a complete welding control hardware system. The specific structure is shown and explained below: I. High-frequency welding power supply As the core of welding energy output, the high-frequency welding power supply integrates power conversion circuit, filter capacitor bank and pre-charging circuit, and adopts a modular layout to ensure the stability of high current output.

[0032] (a) Power conversion circuit The power conversion circuit is a full-bridge inverter structure, specifically including inverter transistors (Q1, Q2, Q3, Q4), freewheeling diodes (D7, D8, D12, D13), and a power transformer (T1). The output of the inverter transistors is directly connected to the primary winding of the power transformer (T1) to convert the input electrical energy into a high-frequency inverter waveform. The freewheeling diodes are connected in parallel with the inverter transistors, forming a reverse current path to prevent damage to the inverter transistors due to sudden current changes under high-power conditions. The filter capacitor bank, consisting of multiple capacitors (C4, C5, C6, C9, C10, C11), is connected to the input of the power conversion circuit to filter out ripple components in the input voltage, ensuring the stability of the inverter input.

[0033] (ii) Pre-charging circuit The pre-charging circuit is connected in series with the filter capacitor bank and includes a diode group (D1-D6), a current-limiting resistor group (R2-R4), and a power contactor (K1). The diode group and the current-limiting resistor group are connected in series, with one end connected to the power input and the other end connected to the filter capacitor bank. The two ends of the power contactor (K1) are connected to the input and output terminals of the current-limiting resistor group, forming a parallel bypass structure. This circuit achieves slow charging of the filter capacitor bank through the voltage division effect of the current-limiting resistor group, avoiding the large current surge at power-on.

[0034] The specific circuit structures of the pre-charging circuit and the power conversion circuit are as follows: Figure 2 As shown.

[0035] II. Single-cycle energy monitoring module The single-cycle energy monitoring module is used for the acquisition and preliminary processing of electrical signals during the welding process. Its hardware structure includes a current sensor, a voltage sensor, an energy integrator, and a dual-redundant decision circuit. Signal transmission is achieved through shielded cables and printed circuit board wiring between the components. Figure 3 As shown.

[0036] Both the current and voltage sensors are connected to the output of the high-frequency welding power supply via terminal blocks. The sensor signal outputs are connected to the signal input port of the energy integrator via shielded cables. The shielded cables reduce electromagnetic interference in the high-frequency welding environment. The energy integrator is a digital signal processor (DSP), integrated into the monitoring module via a soldered circuit board, forming a short signal transmission path with the sensors. The processor executes the conventional integration algorithm for resistance welding energy calculation; the specific calculation formula is as follows: (This formula is a classic energy integration formula and is known in the field.) It should be noted that this utility model does not protect the integration algorithm itself, but only the DSP hardware processor equipped with the algorithm and its connection structure with the sensor.

[0037] The dual-redundant decision circuit is integrated with the energy integration processor on the same printed circuit board, including a main decision unit and a secondary decision interface. The main decision unit is a hardware logic circuit module inside the processor, which is directly connected to the signal output terminal of the energy integration processor; the secondary decision interface is a standard communication interface, located on the side of the monitoring module's housing, for connecting an external ultrasonic detection module or visual imaging module, forming a dual decision path at the hardware level.

[0038] Preferably, the main judgment unit is a hardware comparator logic module integrated inside the DSP (such as model TMS320F28335). Its preset energy threshold is configured through onboard DIP switches or hardware registers. It can directly receive the 16-bit digital signal output by the energy integration processor and complete the comparison. The secondary judgment interface adopts a standard RS485 communication interface with a MAX485 chip. It is used to connect an external ultrasonic detection module (such as model CSM-100) or a visual imaging module (such as model MV-CE050-30GM). The interface pin definitions are compatible with general testing equipment.

[0039] It should be noted that this utility model only seeks protection for the above-mentioned hardware structure. The related signal processing workflow is only for reference by those skilled in the art and is not the object of protection of this solution.

[0040] III. Closed-loop feedback actuator The closed-loop feedback actuator, serving as the execution unit for parameter adjustment, includes an adjustment circuit and connection terminals. The adjustment circuit is structurally connected to the energy integral processor of the single-cycle energy monitoring module and the power conversion circuit of the high-frequency welding power supply via the connection terminals, such as... Figure 4 .

[0041] The regulating circuit integrates a current regulation unit and a pulse width regulation unit, both of which are connected to the connection terminals via metal pins. The connection terminals adopt a pluggable structure, with one end connected to the control signal output terminal of the energy integrator via a wire, and the other end connected to the inverter tube drive port of the power conversion circuit via a dedicated wiring harness. This enables hardware transmission of monitoring signals to regulation commands, constructing a closed-loop hardware link from signal acquisition to parameter adjustment.

[0042] IV. Water-cooled temperature control subsystem The water-cooled temperature control subsystem is designed for the core heat-generating components of the high-frequency welding power supply. It includes a cooling channel, a deionized water circulation loop, and a temperature controller. Temperature management is achieved through a combination of fluid heat dissipation and hardware regulation. Figure 5 As shown.

[0043] The cooling channel adopts a multi-layer copper tube structure. The surface of the copper tube is attached to the iron core of the transformer (T1) and the surface of the IGBT module (the core component of the inverter tube group), and is fixed with clamps to form a tight contact, ensuring efficient heat conduction. The deionized water circulation loop consists of a water pump, a water storage tank, and connecting pipes. One end of the pipe is connected to the outlet of the water pump, and the other end is connected to the inlet of the multi-layer copper tube. The return end is connected to the water storage tank through a pipe, forming a closed circulation path.

[0044] The temperature controller uses an embedded PID controller, which is fixed inside the housing of the water cooling subsystem by a bracket. Its signal input terminal is connected to the temperature sensor through a wire, and the temperature sensor is attached to the surface of the IGBT module. The output terminal of the controller is connected to the water pump drive motor of the water circulation loop, and the linkage control between the temperature signal and the water pump operation status is realized through the hardware interface.

[0045] V. Other Auxiliary Structures (a) Protection circuit group A protection circuit group is connected in series on the power transmission branch of the high-frequency welding power supply. This circuit group has a modular structure and includes overcurrent protection, overvoltage protection, high-temperature protection, and short-circuit protection circuits. Each protection circuit is connected in series, with its input terminal connected to the output terminal of the power conversion circuit, and its output terminal connected to the welding load. Multiple safety protections for the system are achieved through hardware fusing and voltage clamping mechanisms, such as... Figure 6 As shown.

[0046] As a preferred embodiment, the specific implementation is as follows: the overcurrent protection circuit uses a 100A fast-blow fuse connected in series with a current relay (model JZC-44F); the overvoltage protection circuit uses a varistor (model 10D471K) connected in parallel with the power output terminal; the high temperature protection circuit uses a normally closed temperature switch (model KSD9700, operating temperature 85℃) connected in series with the power circuit; the short circuit protection circuit uses a dedicated short circuit protection chip (model LM311) in conjunction with a sampling resistor. All of the above components are standard parts known in the field of power electronics.

[0047] (ii) Solder joint strengthening module The weld joint strengthening module is an independent hardware unit, comprising a weld seam recognition circuit and an energy regulation circuit, which are connected to the single-cycle energy monitoring module and the high-frequency welding power supply via wiring terminals, respectively. The signal input terminal of the weld seam recognition circuit is connected in parallel with the sensor signal link of the single-cycle energy monitoring module to acquire the welding position correlation signal; the output terminal of the energy regulation circuit is connected to the power regulation port of the high-frequency welding power supply via a wire, forming a hardware path for energy regulation in a specific area, such as... Figure 7 As shown.

[0048] Preferably, the weld seam recognition circuit uses an incremental encoder (such as model E6B2-CWZ6C) coaxially connected to the welding wheel as a position detection element. The A / B phase pulse output terminal of the encoder is connected in parallel with the sensor signal link of the single-cycle energy monitoring module through an optocoupler isolation circuit. The position of the weld point is located by counting the number of pulses, and then the trigger nodes of the first 15 weld points at the start end (S) and the last 15 weld points at the end end (E) are identified.

[0049] It should be noted that this utility model only requests protection for the structure of the device. The signal interaction process between the above modules is only for reference by those skilled in the art and is not the object of protection of this solution.
