Description

Technical Field

[0001] The utility model relates to the technical fields of SMT (SMT is the abbreviation of Surface Mounted Technology) patch operation and error prevention control, and in particular to a remote error prevention alarm device. Background Art

[0002] When the material trays on the automatic placement machines in the SMT workshop are running low, a new tray of the same model must be manually replaced. This requires scanning the QR codes of both the old and new trays into the MES (Manufacturing Execution System) using a PDA. The MES then verifies whether the two trays contain the same material. If so, the PDA will indicate a successful connection; if not, an alarm will be issued. This process only uses text notifications, not audible ones. To address the production line's need for an audible alarm, we developed a remote error-proofing alarm device. This device works in conjunction with the MES, with commands sent remotely from the MES triggering the device to activate or deactivate the alarm. Summary of the Invention

[0003] The purpose of the utility model is to provide a remote error prevention alarm device, which needs to be able to communicate with the MES system and be remotely controlled by the MES system.

[0004] To achieve the above objectives, the present invention provides a remote error-proofing alarm device comprising a control box, an audible alarm, and a power adapter. The control box comprises a housing and several electronic components, including a cooling fan, a power indicator light, a network interface, a power adapter interface, a network relay module, a wireless transmitter, and a network extension cable. The cooling fan and power indicator light are mounted on the top cover of the control box, the network interface and power adapter interface are mounted on the side of the control box, the network relay module and the wireless transmitter are mounted within the control box, and the ends of the network extension cable are connected to the input / output terminals of the network relay module and the network interface connection terminals, respectively. The wireless transmitter transmits wireless signals, and a wireless receiver is built into the audible alarm. The network relay module is a programmable module and includes a network port through which external programs can communicate with the relay module. The network relay module includes two sets of two-way relay outputs, and the wireless transmitter includes two leads connected to the first set of two-way outputs of the network relay module. In this invention, the MES system sends commands to the control box via the network to control the opening and closing of the relay outputs, thereby remotely triggering or deactivating the alarm signal. The utility model has the advantages of small size, simple structure, low cost, stable use and good practicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0008] The figure shows a remote error-proofing alarm device, comprising a control box 1, an audible alarm 2, and a power adapter 3. The control box is characterized by a housing 4 and several electronic components, including a cooling fan 5, a power indicator light 6, a network interface 7, a power adapter interface 8, a network relay module 9, a wireless transmitter 10, and a network extension cable 11. The cooling fan and power indicator light are mounted on the top cover of the control box, while the network interface and power adapter interface are mounted on the side of the control box. The network relay module and wireless transmitter are mounted inside the control box, and the ends of the network extension cable are connected to the input / output terminals of the network relay module and the network interface connection terminals, respectively. The wireless transmitter can transmit wireless signals, and a wireless receiver is built into the audible alarm. The network relay module is a programmable module and includes a network port through which external programs can communicate with the relay module. The network relay module includes two sets of two-way relay outputs, and the wireless transmitter includes two leads, which are connected to the first set of two-way outputs of the network relay module. The power adapter powers the control box. One end plugs into the power adapter port and the other into a 220V outlet. When the power adapter starts supplying power, the power indicator lights up, and the cooling fan and network relay module begin operating. The cooling fan dissipates heat from within the control box to the air, preventing overheating that could shorten the lifespan of the remote error-prevention alarm device or damage it. The network port connects to the company's internal network, enabling communication between the company's MES system and the control box.

[0009] The sound alarm is designed to work in conjunction with a wireless transmitter. The alarm has a built-in wireless receiver, and when the two wires of the wireless transmitter are short-circuited, the alarm will sound. The wireless transmitter's signal is stable, with a transmission distance of up to 30 meters, making it suitable for wireless alarms on production lines. The transmitter consumes very little power, and its built-in button battery ensures long-term operation without the need for an external power source. The alarm simply plugs into a 220V outlet. For practical use, place the alarm near an SMT placement machine and install the control box in a location with a network connection in the workshop.

[0010] The network relay module is a programmable relay module that includes a network interface. External programs can send commands to it via the TCP / IP protocol to control the opening and closing of its output relays. This network relay module has two sets of relay outputs, but we will only use the first set. Connect the two wires of the wireless transmitter to the normally open terminal and the common terminal of the first set of relay outputs of the network relay module, respectively. By controlling the opening and closing of the first set of relay outputs, we can control the sound alarm.

[0011] The method of using this utility model is as follows:

[0012] Step 1) Install the sound alarm on a 220V socket next to the SMT placement machine. Plug one end of the power adapter into the power adapter port on the control box and the other end into a 220V socket. Plug one end of the network cable into the workshop network interface and the other end into the network port on the control box to connect the control box to the company network.

[0013] Step 2) When receiving materials, the employee first uses a PDA to scan the barcodes of the old and new material trays into the MES system. If the material number is correct, the PDA prompts that the material receiving operation is completed, and the sound alarm does not sound. If the material number is incorrect, the MES system sends a command to the network relay module through the network, closing the first set of relay outputs, thereby short-circuiting the two leads of the wireless transmitter, triggering the sound alarm to sound, and the PDA will pop up an alarm message indicating that the material receiving error occurred.

[0014] Step 3) After the employee confirms the alarm information, the MES system sends a command to the network relay module to disconnect the first set of relay outputs, thereby disconnecting the two leads of the wireless transmitter and turning off the alarm of the sound alarm.

[0015] Step 4) The employee reconfirms the correct material tray and repeats steps 2 and 3 until the material receiving operation is completed.

[0016] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
