Description

Technical Field

[0001] The present application relates to the field of engine production technology, and in particular to an engine assembly roller speed regulation method, device, equipment and readable storage medium. Background Art

[0002] The assembly of the whole engine needs to be completed on the roller conveyor of the production line. Specifically, the operators in each position tighten, glue, test and other operations on the engine assembly transported to the process by the roller conveyor at the corresponding process position of the line body according to the assembly process requirements to realize the assembly of the engine assembly off the line. Among them, the control logic of the continuous conveying roller conveyor of the engine assembly line is to equip each roller conveyor with a variable frequency motor and inverter, and integrate them into a dedicated industrial computer for unified control. However, before the whole engine assembly is carried out, the speed of the continuous conveying roller conveyor of the engine assembly line (that is, the number of engines produced per minute) needs to be adjusted.

[0003] In the related technology, the current beat is referred to, and the corresponding frequency converter frequency is adjusted by a dedicated industrial computer based on experience. Then the timing is manually performed to determine whether the roller transmission speed meets the beat requirements.

[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0050] The embodiments of the present application provide a method, device, equipment and readable storage medium for regulating the speed of an engine assembly roller, which can solve the problems of low regulation efficiency and poor accuracy existing in the related art.

[0051] To solve the above technical problems, the overall idea of ​​this application is as follows:

[0052] A speed regulating method for an engine assembly roller table, the method comprising the following steps:

[0053] Step S10: obtaining a preset production beat value and roller table fixed parameters;

[0054] Step S20: Calculating the input operating frequency of the roller table variable frequency motor based on the preset production tact value and the roller table fixed parameters;

[0055] Step S30: adjusting the actual rotation speed of the roller table variable frequency motor according to the input working frequency of the roller table variable frequency motor to achieve speed control of the roller table.

[0056] See also Figure 1 As shown, the embodiment of the present application provides a roller speed control method for engine assembly, comprising the following steps:

[0057] Step S10: Obtaining a preset production rhythm value and roller fixed parameters; wherein the roller fixed parameters include the transmission ratio between the roller variable frequency motor and the roller wheel, the rated operating frequency of the roller variable frequency motor, the rated output speed of the roller variable frequency motor, the diameter of the roller wheel, and the distance between two adjacent engines to be assembled.

[0058] For example, in this embodiment, since the speed output by the roller table variable frequency motor drives the roller table roller to operate at a fixed speed ratio through the fixed transmission mechanism of the roller table, formula (1) can be obtained:

[0059] i=N1 / N2 (1)

[0060] In the formula, i represents the transmission ratio between the roller table variable frequency motor and the roller table roller, N1 represents the output speed of the roller table variable frequency motor (n / min), and N2 represents the speed of the roller table roller per minute (n / min);

[0061] Since the moving distance of the roller in unit time is equal to the number of rotations of the roller in unit time multiplied by the circumference of the roller, we can get formula (2):

[0062] S=V*t=N2*t*π*D

[0063] V=N2*π*D (2)

[0064] In the formula, S represents the moving distance of the roller, V represents the working speed of the roller (m / min), t represents the unit time (min), and D represents the roller diameter (m);

[0065] At the same time, since the roller movement distance per unit time is equal to the product spacing multiplied by the number of units produced per unit time, formula (3) can be obtained:

[0066] S=V*t=d*t*h

[0067] V=d*h (3)

[0068] In the formula, d represents the product spacing (m), and h represents the number of units produced per minute;

[0069] Then, according to the working principle of the variable frequency motor, it can be known that the ratio of the input operating frequency of the roller table variable frequency motor to the rated operating frequency is equal to the ratio of the output speed of the roller table variable frequency motor to the rated output speed. Therefore, formula (4) can be obtained:

[0070] F / F a =N1 / N a (4)

[0071] In the formula, F represents the input operating frequency of the roller table variable frequency motor (Hz), F a Indicates the rated operating frequency of the roller table variable frequency motor (Hz), N a Indicates the rated output speed of the roller table variable frequency motor (n / min);

[0072] By rearranging equations (1) to (4), we can obtain equation (5):

[0073]

[0074] It can be seen that i, F a , d, D and N a All of them are fixed parameters of the roller table, and only h represents the dynamic parameters under different beats. Therefore, it is only necessary to determine the production beat required for production, and the input operating frequency of the roller table variable frequency motor can be calculated by formula (5), and then the speed of the roller table variable frequency motor can be controlled according to the input operating frequency of the roller table variable frequency motor, so that the speed output by the roller table variable frequency motor can drive the roller table roller to operate at the required speed, so as to achieve the purpose of controlling the roller table transmission speed.

[0075] Step S20: Calculating the input operating frequency of the roller table variable frequency motor based on the preset production tact value and the roller table fixed parameters;

[0076] For example, in this embodiment, it can be understood that after obtaining the production beat value required for the preset production, according to the production beat value and the transmission ratio i between the roller table variable frequency motor and the roller table roller, the rated operating frequency F of the roller table variable frequency motor a , Rated output speed of roller table variable frequency motor N a The input operating frequency of the roller table variable frequency motor can be calculated based on the fixed parameters of the roller table, including the diameter D of the roller wheel and the distance d between two adjacent engines to be assembled.

[0077] Furthermore, the step of calculating the input operating frequency of the roller table variable frequency motor based on the preset production tact value and the roller table fixed parameters includes:

[0078] Determining the rotation speed of the roller according to the preset production cycle value, the diameter of the roller and the distance between the two adjacent engines to be assembled;

[0079] Determine the target speed of the roller table variable frequency motor according to the speed of the roller table roller and the transmission ratio between the roller table variable frequency motor and the roller table roller;

[0080] The input operating frequency of the roller table variable frequency motor is calculated according to the target speed of the roller table variable frequency motor, the rated output speed of the roller table variable frequency motor and the rated operating frequency of the roller table variable frequency motor.

[0081] Specifically, the calculation formula of the rotation speed of the roller is:

[0082]

[0083] In the formula, N2 represents the speed of the roller, d represents the distance between two adjacent engines to be assembled, h represents the preset production cycle value, and D represents the diameter of the roller;

[0084] The calculation formula of the target speed of the roller table variable frequency motor is:

[0085] N1=N2*i

[0086] In the formula, N1 represents the target speed of the roller table variable frequency motor, and i represents the transmission ratio between the roller table variable frequency motor and the roller wheel;

[0087] The calculation formula of the input operating frequency of the roller table variable frequency motor is:

[0088]

[0089] In the formula, F represents the input operating frequency of the roller table variable frequency motor.

[0090] For example, in this embodiment, the preset production cycle value h, the diameter D of the roller, and the distance d between two adjacent engines to be assembled are substituted into the first calculation formula to obtain the rotation speed N2 of the roller. The first calculation formula is:

[0091]

[0092] Then, the speed N2 of the roller and the transmission ratio i between the roller variable frequency motor and the roller are substituted into the second calculation formula to obtain the target speed N1 of the roller variable frequency motor. The second calculation formula is:

[0093] N1=N2*i

[0094] Finally, the target speed N1 of the roller table inverter motor and the rated output speed N a And the rated operating frequency F of the roller table variable frequency motor a Substituting into the third calculation formula, the input operating frequency F of the roller table variable frequency motor can be obtained. The third calculation formula is:

[0095]

[0096] It is understandable that the preset production cycle value h, the transmission ratio i between the roller table variable frequency motor and the roller table roller, and the rated operating frequency F of the roller table variable frequency motor can also be directly used. a , Rated output speed of roller table variable frequency motor N a Substitute the diameter D of the roller wheel and the distance d between two adjacent engines to be assembled into the following calculation formula to directly calculate the input working frequency F of the roller variable frequency motor:

[0097]

[0098] It should be understood that no matter which method is used, as long as the preset production beat value and roller fixed parameters are obtained, the input operating frequency of the roller variable frequency motor can be directly calculated. For example, a special control software (such as DFTCS) can be added between the industrial computer and the PLC system, and then the target production beat value h of the production line can be input into the special control software, and combined with the roller fixed parameters (i.e., i, F a , d, D and N a ), according to the above calculation formula, the required control frequency can be automatically output to the frequency converter, so that the frequency converter can adjust the input working frequency F required by the roller table variable frequency motor.

[0099] Step S30: adjusting the actual rotation speed of the roller table variable frequency motor according to the input working frequency of the roller table variable frequency motor to achieve speed control of the roller table.

[0100] For example, in this embodiment, the input working frequency of the roller variable frequency motor is controlled to achieve accurate and rapid adjustment of the actual speed of the roller variable frequency motor, thereby achieving speed control of the roller. For example, the fixed parameters of the roller of the current assembly line are known to be: i = 0.8, d = 2m and D = 0.09m; and taking the SEW brand RF57-DRN71MS6 model motor as an example, the roller motor parameters are: F a =50Hz and N a =7.14r / min; at the same time, in order to meet the production rhythm of 60JPH (Jobs Per Hour) of the line, the preset production rhythm h=1 (i.e., 1 unit per minute); after inputting all the above relevant parameters into the dedicated control software, it can automatically calculate: F=39.6Hz; then the industrial computer sends a signal to make the frequency converter adjust the input working frequency of the roller frequency conversion motor to 39.6Hz, and at this time the roller rhythm is adjusted to 60JPH, thereby meeting the demand. It can be seen that this embodiment realizes one-button automatic roller speed regulation, that is, input the required roller production rhythm, automatically make the frequency converter output the corresponding control signal according to the formula relationship, and adjust the roller motor working frequency to reduce the time consumption of roller speed regulation; at the same time, digital calculation is used instead of traditional manual timing control to make the roller running speed more accurate.

[0101] In summary, the present application optimizes the production line roller speed control method to achieve one-button roller speed automatic control and improve the efficiency and accuracy of roller beat adjustment. That is, it is only necessary to obtain the required roller production beat, and determine the input operating frequency of the roller frequency conversion motor through the production beat and the fixed parameters of the roller. Finally, according to the input operating frequency of the roller frequency conversion motor, the speed of the roller frequency conversion motor can be accurately and quickly adjusted, thereby achieving precise control of the roller running speed. Not only does it not need to rely on experience for repeated adjustments or tests, but it also does not need to control the roller speed through on-site timing, thereby effectively improving the adjustment efficiency and accuracy of the roller running speed.
