[0025] Figure 2 The structural schematic diagram of the portable production rhythm measuring device in one embodiment is shown.

[0026] Figure 3 The system architecture diagram of the portable production rhythm measuring device in another embodiment is shown. DETAILED DESCRIPTION

[0027] The portable production rhythm measuring device will be further explained and described in combination with the drawings and specific embodiments in the specification, however, the explanation and description do not constitute undue limitation on the technical scheme of the portable production rhythm measuring device.

[0028] In the manufacturing field, it is often necessary to measure the actual production cycle of a production component, for example, to measure the action cycle of a certain moving device on a production line, such as a slider, so as to understand the actual production situation and then control the production according to the actual production situation.

[0029] However, the production cycle is currently measured manually by means of manual operation of a stopwatch. This measurement method has low measurement accuracy and low reliability of the measurement result.

[0030] In addition, some production lines use a collection device to collect the action cycle of the action component and then upload it to the manufacturing execution control system of the production line. However, this method needs to modify the existing production line equipment, thereby generating high investment costs and having a very limited application range.

[0031] In order to solve the above problems, the portable production rhythm measuring device provided by the present application can measure the production rhythm of the action component on the production line without modifying the existing production equipment, and can also realize accurate detection of the production rhythm, thereby having high reliability.

[0032] Figure 1 The system architecture diagram of the portable production rhythm measuring device in another embodiment is shown.

[0033] Figure 2 The structure schematic diagram of the portable production rhythm measuring device in another embodiment is shown.

[0034] As shown in Figure 1 and Figure 2 In some embodiments, the portable production rhythm measuring device can include:

[0035] A sensing element 100 is arranged on the side of the moving component to be detected, so as to sense the periodic action of the moving component and convert it into an electrical signal.

[0036] The data processing device 200 is connected to the sensing element 100 via the data line 101 to convert the electrical signal transmitted by the sensing element 100 into a beat digital signal with a time stamp.

[0037] In order to facilitate the adjustment of the positional relationship between the sensing element and the detected motion element, so that the production beat measuring device can be adapted to a variety of measured elements or devices, the portable production beat measuring device of this utility model also includes a bracket 400. The bracket 400 includes a base 401 and an adjusting arm assembly, wherein the adjusting arm assembly is movably connected to the base 401, and the sensing element 100 is disposed on the adjusting arm assembly.

[0038] For example, in a specific instance, a sensing element is used to detect the motion cycle of a slider on a production line from the start point to the end point of its stroke. The base is fixed, and the position of the adjusting arm assembly is adjusted so that the sensing element can be positioned at the start of the sliding stroke. Each time the sensing element detects the slider, it outputs an electrical signal, such as a high-level signal or a low-level signal. Therefore, the time interval between two adjacent electrical signals is the production cycle of the slider. This electrical signal is transmitted to a data processing device, which converts each electrical signal into a time-stamped digital signal. For example, the first electrical signal at second 0 is converted into an electrical signal with a timestamp representing second 0, and the second electrical signal at second 15 is converted into an electrical signal with a timestamp representing second 15. Thus, the production cycle of the slider can be determined from two adjacent time-stamped digital signals.

[0039] Figure 3 The diagram shows the system architecture of the portable production cycle measurement device according to another embodiment of the present invention.

[0040] In such Figure 3 In the illustrated embodiment, the portable production beat measurement device also includes a data analysis device 300, which is data-connected to the data processing device 200 to receive beat digital signals and to present and / or analyze the beat digital signals.

[0041] In other implementations, instead of a separate data analysis device, it can be integrated as a data analysis module within the data processing device, serving as part of the data processing device.

[0042] In some more specific embodiments, the sensing element 100 may include a photoelectric sensor, such as a laser sensor, which emits an electrical signal based on the movement of the detected moving part.

[0043] In some more specific implementations, such as Figure 2 As shown, the data processing device 200 may include:

[0044] The microprocessor 201 converts the electrical signal transmitted by the sensing element 100 into a clock digital signal with a time stamp; the power supply module 202 supplies power to the data processing device 200.

[0045] In some more specific implementations, to further improve the portability of the measuring device and reduce its cost, the microprocessor may employ an Internet of Things (IoT) gateway.

[0046] Of course, in other, more specific implementations, the microprocessor can also be other devices, such as a Raspberry Pi.

[0047] In some more specific implementations, such as Figure 2 As shown, the power supply module can be installed within the data processing device, serving as the device's power supply module. For example, the power supply module can include a battery installed within the data processing device. The battery can be a dry cell battery, a lithium battery, or a rechargeable battery.

[0048] In some other, more specific implementations, the power supply module may also be an external power source, such as a portable power bank.

[0049] like Figure 2 Figure 2 As shown, in some embodiments, the data processing device 200 further includes a voltage conversion module 203 connected between the sensing element 100 and the microprocessor 201.

[0050] In some implementations, the operating voltage of the microprocessor (e.g., 5V) is lower than the voltage of the electrical signal emitted by the sensing element (e.g., 24V). To further ensure the stable operation of the microprocessor, a voltage conversion module 203 can be provided between the sensing element 100 and the microprocessor 201 to convert the high voltage to the low voltage.

[0051] In some more specific implementations, the voltage conversion module can be configured as a relay.

[0052] In addition, in some embodiments, the data processing device 200 may also include a storage module, which can be used to directly store the clock digital signal in the data processing device, thereby achieving data backup or for subsequent data analysis.

[0053] In some embodiments, the data processing device 200 may also include a wireless communication module, such as a WIFI module, through which the data processing device transmits the clock digital signal.

[0054] In some more specific embodiments, the data processing device is connected to the data analysis device 300 via a wireless communication module, thereby transmitting the clock digital signal to the data analysis device 300.

[0055] Of course, in some alternative implementations, the data processing device can also transmit the beat digital signal via a data cable.

[0056] In some more specific embodiments, the data analysis device 300 may be located on the production line site, for example, it may be a computer or processor with data analysis software or hardware installed.

[0057] When it is necessary to present the beat digital signal, the data analysis device has a display to show the beat digital signal.

[0058] In some other, more specific embodiments, the data analysis device may also be configured as an analysis module programmed by computer software, located in a remote cloud.

[0059] In some more specific implementations, the data analysis device can clean the received beat digital signal and then analyze it, for example, extracting the mean, median, maximum and minimum values ​​within a set time window in real time.

[0060] In some more specific embodiments, the adjusting arm assembly may include: a first adjusting arm 402, which is movably connected to the base 401; a second adjusting arm 403, which is movably connected to the first adjusting arm 402, and a sensing element 100 disposed on the second adjusting arm 403.

[0061] In some more specific embodiments, the first adjusting arm 402 can be connected to the base 401 via a universal joint, and the second adjusting arm 403 can be movably connected to the first adjusting arm 402 via a hinge shaft.

[0062] In some more specific embodiments, the base 401 can be configured as a magnetic base, thereby enabling the base to be quickly fixed by magnetic force.

[0063] Therefore, the portable production cycle measurement device of this utility model is small in size and can be directly installed on existing production lines. It is very convenient to install and move, and has a high degree of flexibility and wide adaptability. It is especially suitable for monitoring the periodic processes of moving elements on the production line.

[0064] The portable production cycle measurement device described in this invention outputs a digital signal that can analyze collected data in real time. The data analysis system processes and interprets the data, providing immediate insights and feedback, thereby improving overall production efficiency. Furthermore, real-time data analysis of periodic actions aids in preventative maintenance and troubleshooting of the production line, and also helps identify bottlenecks and areas for improvement in the manufacturing process.

In manual processes, this portable production cycle measuring device can help workers adjust their work steps, improve operational efficiency, and maintain flexibility to adapt to different production needs and changes.
