Description

Technical Field

[0001] The invention relates to a recording device and a recording method for the number of winding turns of a centralized motor stator. Background Art

[0002] The motor stator is the stationary part of the motor, which consists of three parts: the stator core, the stator winding and the frame. The stator winding can be divided into two types: centralized and distributed, according to the shape of the coil winding and the embedded wiring method. Among them, the distributed winding can be wound with a winding machine and then embedded in the stator core; while the centralized winding motor stator, due to its special process, in order to reduce the size of the winding end and reduce the internal resistance of the winding, currently mainly adopts the manual direct winding method, which is carried out by two workers in collaboration. However, manual winding is prone to errors, that is, when two workers use manual counting to count, they may eventually give two different numbers of turns.

[0003] In the traditional counting scheme, two workers each hold a counter. After completing one circle of winding, they press the counter, and the counter displays a number plus one, repeating the cycle until the coil is finished. Finally, the counters of the two workers are compared to determine whether the winding is correct. In this scheme, it is indeed possible to know whether the winding worker has done the winding correctly, but once the numbers on the two counters are different, that is, the worker has made a winding error, it is difficult to find out when the worker made the error and it is impossible to remedy the situation in time. The worker can only remove the coil and rewind it. In this way, the worker's efficiency will become extremely low, and the labor cost of winding the stator will be greatly increased.

[0004] Therefore, a device specifically for counting is needed to avoid errors caused by manual counting.

[0005] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0006] The object of the present invention is to provide a device for recording the number of turns of a centralized motor stator winding, which can solve the problem that winding counting errors cannot be promptly reminded in the current counting scheme.

[0007] Another object of the present invention is to provide a method for recording the number of turns of a centralized motor stator winding, which can promptly alarm when the number of turns wound by two workers is inconsistent, allowing the workers to make corrections in time to avoid losses.

[0008] To achieve the above-mentioned purpose, the present invention provides a device for recording the number of turns of a centralized motor stator winding, comprising a comparator, a first counting switch, a second counting switch, an alarm and a counting display; the first counting switch is electrically connected to the comparator; the second counting switch is electrically connected to the comparator; the alarm is electrically connected to the comparator; the counting display is electrically connected to the comparator; wherein when one of the first counting switch and the second counting switch is pressed once, and the other of the first counting switch and the second counting switch is also pressed once within a predetermined time, the comparator sends a counting instruction to the counting display, and the counting display increases the count once after receiving the counting instruction.

[0009] In a preferred embodiment, when one of the first counting switch and the second counting switch is pressed once, and the other of the first counting switch and the second counting switch is not pressed once within a predetermined time, the comparator sends an alarm instruction to the alarm, and the alarm sends an alarm signal after receiving the alarm instruction, and the counting display does not increase the count.

[0010] In a preferred embodiment, the predetermined time is 0 to 5 seconds.

[0011] In a preferred embodiment, the counting display includes a count modification button. When one of the first counting switch and the second counting switch is pressed once due to an erroneous operation, the other of the first counting switch and the second counting switch is also pressed once within a predetermined time, and the counting display counts once. After the erroneous operation is verified and confirmed, the count can be deleted once through the count modification button.

[0013] In a preferred embodiment, the counting display further comprises a power failure protection device. When an unexpected power failure occurs, the power failure protection device can automatically save the number of times recorded by the counting display during the power failure.

[0014] In a preferred embodiment, the recording device for the number of turns of the stator winding of the centralized motor also includes a monitoring video device, which can monitor the entire work process of the winding worker, and the monitoring video device can verify whether the wrong operation is true.

[0015] To achieve the above-mentioned purpose, the present invention also provides a method for recording the number of turns of a centralized motor stator winding, which is applied to a recording device such as a period number, and the recording method includes the following steps: checking that the power supply of the recording device and the working status of the counting display and the alarm are in normal state; two winding workers start the winding work, when one winding worker completes one circle and presses one of the first counting switch and the second counting switch once; when the other winding worker also completes one circle within a predetermined time and presses the other of the first counting switch and the second counting switch once, the comparator sends a counting instruction to the counting display, and the counting display increases the count once after receiving the counting instruction; and repeating the above steps until the number of times recorded by the counting display reaches the specified number of winding turns, and the winding work is completed.

[0016] In a preferred embodiment, the method for recording the number of turns of the stator winding of a centralized motor also includes the following steps: in the aforementioned steps, when a winding worker mistakenly presses one of the first counting switch and the second counting switch once before completing one circle, and within a predetermined time, another winding worker completes one circle and presses the other of the first counting switch and the second counting switch once, the comparator sends a counting instruction to the counting display, and when the counting display increases the count once after receiving the counting instruction, the wrong operation can be verified through the video recording equipment, and the count can be deleted once through the count modification button.

[0017] In a preferred embodiment, the method for recording the number of turns of the stator winding of a centralized motor also includes the following steps: in the aforementioned steps, when a winding worker completes one circle and presses one of the first counting switch and the second counting switch once, and within a predetermined time, another winding worker completes one circle and does not press the other of the first counting switch and the second counting switch once, the comparator sends a counting instruction to the counting display, and when the counting display increases the count once after receiving the counting instruction, the video recording device can be used to verify that the missed press is true, and the counting modification button can be used to increase the number of records of the counting display by one.

[0018] Compared with the prior art, the recording device and recording method for the number of turns of the stator winding of a centralized motor of the present invention have the following beneficial effects: the device uses a comparator to compare whether the time difference between the two counting switches being pressed successively meets the predetermined time, and can not only obtain the final number of turns wound, but also can promptly alarm when the number of turns wound by two workers is inconsistent, so that the workers can make corrections in time to avoid losses.

[0022] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation modes.

[0023] Unless explicitly stated otherwise, throughout the specification and claims, the term “comprise” or variations such as “include” or “comprising”, etc., will be understood to include the stated elements or components but not to exclude other elements or components.

[0024] like Figure 1 As shown, a device for recording the number of stator winding turns of a centralized motor according to a preferred embodiment of the present invention mainly includes a comparator 1, a first counting switch SB1, a second counting switch SB2, an alarm 2, and a counting display 3. The first counting switch SB1 is electrically connected to the comparator 1. The second counting switch SB2 is electrically connected to the comparator 1; the alarm 2 is electrically connected to the comparator 1. The counting display 3 is electrically connected to the comparator 1.

[0025] In some embodiments, when one of the first counting switch SB1 and the second counting switch SB2 is pressed once, and the other of the first counting switch SB1 and the second counting switch SB2 is also pressed once within a predetermined time, the comparator 1 sends a counting instruction to the counting display 3, and the counting display 3 increases the count once after receiving the counting instruction. When one of the first counting switch SB1 and the second counting switch SB2 is pressed once, and the other of the first counting switch SB1 and the second counting switch SB2 is not pressed once within a predetermined time, the comparator 1 sends an alarm instruction to the alarm 2, and the alarm 2 sends an alarm signal after receiving the alarm instruction, and the counting display 3 does not increase the count.

When an unexpected power failure occurs, the power failure protection device can automatically save the number of times recorded by the counting display 3 during the power failure. The storage time of the number of times recorded by the power failure protection device can be set arbitrarily, and generally should not be less than 24 hours, but the present invention is not limited thereto.

[0028] In some embodiments, the recording device for the number of turns of the stator winding of the centralized motor further includes a monitoring video device (not shown), which can monitor the entire work process of the winding worker, and the monitoring video device can verify whether the wrong operation is true. The monitoring video device has more than one monitoring head, and should be able to monitor the entire working scene in all directions.

[0029] To achieve the above-mentioned purpose, the present invention also provides a method for recording the number of turns of the stator winding of a centralized motor, which is applied to a recording device such as a period number, and the recording method includes the following steps: first, check that the power supply of the recording device and the working states of the counting display 3 and the alarm 2 are in normal state. After the inspection, two winding workers start the winding work, and when one winding worker completes a circle and presses one of the first counting switch SB1 and the second counting switch SB2 once. When the other winding worker also completes a circle within a predetermined time and presses the other of the first counting switch SB1 and the second counting switch SB2 once, the comparator 1 sends a counting instruction to the counting display 3, and the counting display 3 increases the count once after receiving the counting instruction; and repeat the above steps until the number of times recorded by the counting display 3 reaches the specified number of winding turns, and the winding work is completed.

[0030] In some embodiments, the method for recording the number of turns of the stator winding of a centralized motor further includes the following steps: in the aforementioned steps, when a winding worker mistakenly presses one of the first counting switch SB1 and the second counting switch SB2 once before completing one circle, and within a predetermined time, another winding worker completes one circle and presses the other of the first counting switch SB1 and the second counting switch SB2 once, the comparator 1 sends a counting instruction to the counting display 3, and when the counting display 3 increases the count once after receiving the counting instruction, the wrong operation can be verified through the video recording device, and the count can be deleted once through the count modification button.
