Description

Technical Field

[0002] Coating is a process method of forming a new surface on the surface of substrates such as glass using different materials, and its purpose is to make the surface layer of the substrate meet requirements such as glossiness, oxidation resistance, and weather resistance.

[0003] In the current coating production process, several substrates that are first coated in each pack of substrates need to be film-coated, and the substrates that have completed the film-coating operation cannot be powder-sprayed. The remaining substrates that have not been film-coated need to be powder-sprayed, otherwise it is easy to cause scratches or abrasions on the substrates due to collisions and rubbings between the substrates. Existing film-coating equipment and powder-spraying equipment need to be manually started and stopped by operators, and there are often problems such as powder-spraying the substrates that have completed the film-coating operation by mistake because the powder-spraying equipment is not turned off in time, and forgetting to turn on the powder-spraying equipment after the film-coating is completed and failing to powder-spray the remaining substrates, resulting in unqualified product batches.

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0050] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0051] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, if "and / or" or "and / or" appears throughout the text, its meaning includes three parallel scenarios. Taking "A and / or B" as an example, it includes scenario A, or scenario B, or the scenario where both A and B are satisfied simultaneously. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0052] Embodiments of the present invention provide a coating control circuit. Please refer to Figure 1 , the coating control circuit includes a metering circuit 1, a reset circuit 2, and a main control circuit 3; where:

[0053] The metering circuit 1 is configured to output a first metering signal when reaching a first metering value, and the metering circuit 1 is further configured to output a second metering signal when reaching a second metering value; the first metering value is less than the second metering value.

[0054] The input end of the reset circuit 2 is electrically connected to the output end of the metering circuit 1, and the reset circuit 2 is configured to reset the metering circuit 1 according to the second metering signal.

[0055] The input end of the main control circuit 3 is electrically connected to the output end of the metering circuit 1; the main control circuit 3 includes a first output end and a second output end. The first output end is used to connect to a film laminating machine 4, and the second output end is used to connect to a powder spraying machine 5; the main control circuit 3 is configured to output a film laminating start signal through the first output end when powered on; the main control circuit 3 is configured to output a powder spraying start signal through the second output end and stop outputting the film laminating start signal through the first output end according to the first metering signal; the main control circuit 3 is configured to output a film laminating start signal through the first output end and stop outputting the powder spraying start signal through the second output end according to the second metering signal.

[0056] Specifically, the function of the metering circuit 1 is to count the number of workpieces to be coated passing through the preset area. In this way, the coating situation of the workpieces to be coated can be determined according to the metering value of the metering circuit 1. For example, when the preset area is set at the outlet end of the film laminating machine 4, the metering value represents the number of workpieces to be coated passing through the film laminating machine 4. Among them, the metering circuit 1 can count the number of workpieces to be coated by direct metering or indirect metering. When using the direct metering method, the metering circuit 1 can directly measure the number of workpieces to be coated with the help of recognition devices such as photosensitive sensors. At this time, the first metering value and the second metering value are specific numerical values. The first metering value is the number of workpieces to be coated that need to be film laminated in each batch of workpieces to be coated, and the second metering value is the total number of workpieces to be coated in each batch. When using the indirect metering method, the metering circuit 1 can perform a timing operation with the help of a timer. When the moving speed of the workpieces to be coated remains unchanged, the time for each workpiece to pass through the preset area is equal. Therefore, the number of workpieces to be coated passing through the preset area can be determined according to the time measured by the timer. At this time, the first metering value and the second metering value are time values. The first metering value is the time required for several workpieces to be coated that need to be film laminated in each batch of workpieces to be coated to pass through the preset area, and the second metering value is the time required for all the workpieces to be coated in each batch to pass through the preset area. In the specific implementation process, the metering method of the metering circuit 1 can be set according to the actual situation, which is not limited here.

[0057] The reset circuit 2 is used to clear the metering value of the metering circuit 1 through a reset operation after all the workpieces to be coated in each batch have passed through the preset area (that is, when receiving the second metering signal output by the metering circuit 1). In this way, when the next batch of workpieces to be coated enters the preset area, the metering circuit 1 can start the metering operation again to continue to trigger the corresponding devices to perform corresponding operations through the first metering signal and the second metering signal.

[0058] When the main control circuit 3 outputs a film lamination start signal through the first output terminal, the film laminating machine 4 is turned on and enters the working state. At this time, the film laminating machine 4 can perform a film lamination operation on the passing workpieces to be coated. When the main control circuit 3 stops outputting the film lamination start signal through the first output terminal, the film laminating machine 4 is turned off. At this time, the film laminating machine 4 no longer performs a film lamination operation on the passing workpieces to be coated. Similarly, when the main control circuit 3 outputs a powder spraying start signal through the second output terminal, the powder spraying machine 5 is turned on and enters the working state. At this time, the powder spraying machine 5 can perform a powder spraying operation on the passing workpieces to be coated. When the main control circuit 3 stops outputting the powder spraying start signal through the second output terminal, the powder spraying machine 5 is turned off. At this time, the powder spraying machine 5 no longer performs a powder spraying operation on the passing workpieces to be coated.

[0059] Based on the above settings of the coating control circuit, the specific working process of the coating equipment applying this coating control circuit is described as follows:

[0060] Please refer to Figure 4, taking the glass to be coated as an example, in the actual coating process, multiple pieces of glass can be successively placed on the conveying device 7, and the multiple pieces of glass are arranged in a straight line from front to back; the film laminating machine 4 and the powder spraying machine 5 are arranged at intervals along the conveying direction of the conveying device 7, and each piece of glass is driven by the conveying device 7 to successively pass through the film laminating machine 4 and the powder spraying machine 5. Since the coating process for glass usually involves film laminating operation on the first piece of glass in each batch of glass, and powder spraying operation on the remaining glass, when the number of glass pieces in each batch is 10, the metering circuit 1 can directly measure the number of glass pieces passing through the film laminating machine 4, set the first metering value to 1, and set the second metering value to 10.

[0061] In the first stage, that is, before the first piece of the first batch of glass reaches the film laminating machine 4, the device is powered on, triggering the main control circuit 3 to output a film laminating start signal through the first output terminal, and the film laminating machine 4 is turned on and enters the working state to perform film laminating operation on the first piece of glass passing through the film laminating machine 4;

[0062] In the second stage, the first piece of glass has completely passed through the film laminating machine 4 and completed the film laminating operation. After the metering circuit 1 recognizes this piece of glass, the metering value becomes 1. At this time, the metering value of the metering circuit 1 reaches the first metering value, and the metering circuit 1 outputs a first metering signal, triggering the main control circuit 3 to output a powder spraying start signal through the second output terminal and stop outputting the film laminating start signal through the first output terminal, so that the film laminating machine 4 is turned off and the powder spraying machine 5 is turned on and enters the working state; thus, when the 9 pieces of glass after the first piece of glass pass through the film laminating machine 4, the film laminating machine 4 will not perform film laminating operation on these 9 pieces of glass; and when the 9 pieces of glass after the first piece of glass pass through the powder spraying machine 5, the powder spraying machine 5 will perform powder spraying operation on these 9 pieces of glass; during this process, the metering circuit 1 will continuously count the number of glass pieces passing through the film laminating machine 4;

[0063] In the third stage, when all 10 pieces of glass in this batch have passed through the film laminating machine 4, the measured value of the measurement circuit 1 reaches the second measured value. The measurement circuit 1 outputs a second measurement signal, triggering the reset circuit 2 to perform a reset operation on the measurement circuit 1. At the same time, it triggers the main control circuit 3 to output a film laminating start signal through the first output terminal and stop outputting a powder spraying start signal through the second output terminal, causing the powder spraying machine 5 to close and the film laminating machine 4 to start and enter the working state. Thus, when the first piece of glass in the next batch of glass passes through the film laminating machine 4, the film laminating machine 4 will perform a film laminating operation on this first piece of glass; and when the first piece of glass in the next batch of glass passes through the powder spraying machine 5, the powder spraying machine 5 will not perform a powder spraying operation on this first piece of glass. During this process, the reset measurement circuit 1 will start counting the number of glasses passing through the film laminating machine 4 again from zero; when the measured value of the measurement circuit 1 reaches the first measured value again, the measurement circuit 1 will output the first measurement signal again and trigger the main control circuit 3 to perform the corresponding operation; and when the measured value of the measurement circuit 1 reaches the second measured value again, the measurement circuit 1 will output the second measurement signal again and trigger the reset circuit 2 and the main control circuit 3 to perform the corresponding operations.

[0064] Based on the above cyclic process, the corresponding film laminating operation and powder spraying operation can be automatically performed on each batch of glass passing through the film laminating machine 4 and the powder spraying machine 5 in turn according to the preset coating operation rules (the first piece of glass in each batch of glass is subjected to a film laminating operation, and the remaining glass is subjected to a powder spraying operation) until the film laminating operation and powder spraying operation on all batches of glass are completed.

[0065] It can be seen that the coating control circuit provided in this embodiment adopts an automatic control method. After the device is powered on, the film laminating machine 4 can perform film laminating operations on several pieces of workpieces to be coated that first pass through the film laminating machine 4 among the first batch of workpieces to be coated; when the film laminating operations on these several pieces of workpieces to be coated are completed and they completely pass through the film laminating machine 4, the measurement value of the measurement circuit 1 reaches the first measurement value, and the measurement circuit 1 outputs a first measurement signal, triggering the main control circuit 3 to control the film laminating machine 4 to close and the powder spraying machine 5 to start; thus, when the remaining workpieces to be coated in the first batch pass through the film laminating machine 4, the film laminating machine 4 will not perform film laminating operations on the remaining workpieces to be coated; and when the remaining workpieces to be coated in the first batch pass through the powder spraying machine 5, the powder spraying machine 5 will perform powder spraying operations on the remaining workpieces to be coated; when all the workpieces to be coated in the first batch pass through the film laminating machine 4, the measurement value of the measurement circuit 1 reaches the second measurement value, and the measurement circuit 1 outputs a second measurement signal, triggering the reset circuit 2 to perform a reset operation on the measurement circuit 1, and at the same time triggering the main control circuit 3 to control the powder spraying machine 5 to close and the film laminating machine 4 to start; thus, the film laminating machine 4 can perform film laminating operations on several pieces of workpieces to be coated that first pass through the film laminating machine 4 among the next batch of workpieces to be coated; and when these several pieces of workpieces to be coated pass through the powder spraying machine 5, the powder spraying machine 5 will not perform powder spraying operations on these several pieces of workpieces to be coated; during this process, the reset measurement circuit 1 will start counting the number of workpieces to be coated passing through the film laminating machine 4 from zero again; when the measurement value of the measurement circuit 1 reaches the first measurement value again, the measurement circuit 1 will output the first measurement signal again and trigger the main control circuit 3 to perform corresponding operations; and when the measurement value of the measurement circuit 1 reaches the second measurement value again, the measurement circuit 1 will output the second measurement signal again and trigger the reset circuit 2 and the main control circuit 3 to perform corresponding operations; and so on in a cycle until the film laminating operations and powder spraying operations on all batches of workpieces to be coated are completed. This coating control circuit realizes the automatic cooperation between the film laminating machine 4 and the powder spraying machine 5, enables the film laminating operations and powder spraying operations to be coordinated with the actual conveying situation of the workpieces to be coated, eliminates the need for manual control of the start and stop of the film laminating machine 4 and the powder spraying machine 5, thus avoiding the problem of unqualified product batches caused by human operation errors, improving the batch production quality of the workpieces to be coated, and realizing the continuous production of multiple batches of workpieces to be coated, enhancing the automation level of the device.

[0066] Optionally, referring to Figure 2 and Figure 4 , the coating control circuit includes a delay circuit 6; the input end of the delay circuit 6 is electrically connected to the output end of the measurement circuit 1, and the output end of the delay circuit 6 is electrically connected to the input end of the main control circuit 3.

[0067] The delay circuit 6 is used to output a first trigger signal to the main control circuit 3 when receiving the first measurement signal, and the delay circuit 6 is used to output a second trigger signal to the main control circuit 3 when receiving the first measurement signal and after a first preset time; the main control circuit 3 is used to stop outputting the film pasting start signal through the first output end when receiving the first trigger signal, and the main control circuit 3 is used to output the powder spraying start signal through the second output end when receiving the second trigger signal.

[0068] During the actual operation process, the metering circuit 1 usually counts the number of workpieces to be coated by means of the recognition device 8 at the outlet end of the film pasting machine 4; based on this setting method, taking the example that the first workpiece in each batch of workpieces to be coated needs to be pasted with film and the rest need to be sprayed with powder, at the time node when the first workpiece to be coated completely passes through the film pasting machine 4 and is recognized by the recognition device 8 at the outlet end of the film pasting machine 4, thus triggering the metering circuit 1 to output the first measurement signal, the first workpiece to be coated has not passed through the powder spraying machine 5. At this time, if the powder spraying machine 5 is immediately started to perform the powder spraying operation, it may mis-spray the first workpiece to be coated that has been pasted with film, thus destroying the coating production requirements.

[0069] Based on the above application situation, in this embodiment, by setting the delay circuit 6, when the metering circuit 1 outputs the first measurement signal, the delay circuit 6 can immediately trigger the main control circuit 3 to stop outputting the film pasting start signal through the first output end, so as to ensure that the film pasting machine 4 is immediately turned off after the first workpiece in each batch of workpieces to be coated completes the film pasting operation, thus avoiding mis-pasting the remaining workpieces to be coated after the first workpiece to be coated; at the same time, when the metering circuit 1 outputs the first measurement signal, the delay circuit 6 can trigger the main control circuit 3 to output the powder spraying start signal through the second output end after a first preset time, so as to ensure that the powder spraying machine 5 is started after the first workpiece to be coated completely passes through the powder spraying machine 5, so as to avoid mis-spraying the first workpiece to be coated.

[0070] Wherein, the first preset time can be specifically set according to the conveying speed of the conveying device 7 as the time required for the first workpiece to be coated to leave the film pasting machine 4 until the workpiece to be coated completely passes through the powder spraying machine 5. The delay circuit 6 can specifically adopt a capacitor delay circuit 6, a relay delay circuit 6, etc., as long as it can play the function of delaying the electrical signal, and it is not limited here.

[0071] Optionally, referring to Figure 2 and Figure 4 , the coating control circuit includes a delay circuit 6; the input end of the delay circuit 6 is electrically connected to the output end of the metering circuit 1, and the output end of the delay circuit 6 is electrically connected to the input end of the main control circuit 3.

[0072] The delay circuit 6 is used to output a third trigger signal to the main control circuit 3 when receiving the second measurement signal, and the delay circuit 6 is used to output a fourth trigger signal to the main control circuit 3 after receiving the second measurement signal and passing through the second preset time; the main control circuit 3 is used to output a film laminating start signal through the first output terminal when receiving the third trigger signal, and the main control circuit 3 is used to stop outputting the powder spraying start signal through the second output terminal when receiving the fourth trigger signal.

[0073] In the actual operation process, taking the example that the first piece of each batch of workpieces to be coated needs film laminating and the rest need powder spraying, after the last piece of the current batch of workpieces to be coated completes the powder spraying operation, the first piece of the next batch of workpieces to be coated will continue with the film laminating operation; the following situation may occur: when the first piece of the next batch of workpieces to be coated is performing the film laminating operation at the film laminator 4, the last piece of the previous batch of workpieces to be coated is still performing the powder spraying operation at the powder sprayer 5.

[0074] Based on the above situation, in this embodiment, by setting the delay circuit 6, when the metering circuit 1 outputs the second measurement signal, the delay circuit 6 can immediately trigger the main control circuit 3 to output the film laminating start signal through the first output terminal, so as to timely start the film laminator 4 and perform the film laminating operation on the first piece of the next batch of workpieces to be coated after the last piece of the previous batch of workpieces to be coated passes through the film laminator 4; at the same time, when the metering circuit 1 outputs the second measurement signal, the delay circuit 6 can trigger the main control circuit 3 to stop outputting the powder spraying start signal through the second output terminal after passing through the second preset time, so as to ensure that the powder sprayer 5 is turned off after the last piece of the previous batch of workpieces to be coated completes the powder spraying operation.

[0075] Among them, the second preset time can be specifically set according to the conveying speed of the conveying device 7 as the time required for the last piece of the workpiece to be coated to leave the film laminator 4 and completely pass through the powder sprayer 5. The delay circuit 6 can specifically adopt a capacitor delay circuit 6, a relay delay circuit 6, etc., as long as it can play the function of delaying the electrical signal, and it is not limited here.

[0076] Optionally, referring to Figure 3 , in a specific embodiment, the coating control circuit includes a driving end A, a first normally open contact KA1, a second normally open contact KA2, a film laminating input counting end C1, a film laminating output counting end C2, a first normally closed contact KA7, a third normally open contact KA3, a second normally closed contact KA8, a first trigger end KA10, a fourth normally open contact KA4, a normally closed delay disconnecting contact KT3, a second trigger end KT1, a third trigger end KA11, a normally open delay closing contact KT4, a fourth trigger end KA12, a fifth normally open contact KA5, a fifth trigger end KA13, a sixth normally open contact KA6 and a sixth trigger end KT2.

[0077] The driving end A is connected to one end of the first normally open contact KA1, one end of the first normally closed contact KA7, one end of the fourth normally open contact KA4, one end of the normally open delay-on contact KT4, one end of the third normally open contact KA3, and one end of the sixth normally open contact KA6; the other end of the first normally open contact KA1 is connected to the film pasting input counting terminal C1 and the film pasting output counting terminal C2; the film pasting input counting terminal C1 is connected to the control terminal of the first normally closed contact KA7; the film pasting output counting terminal C2 is connected to the control terminal of the third normally open contact KA3; the other end of the first normally closed contact KA7 is connected to one end of the second normally open contact KA2; the other end of the second normally open contact KA2 is connected to the other end of the fourth normally open contact KA4, one end of the second normally closed contact KA8, and one end of the normally closed delay-off contact KT3; the other end of the second normally closed contact KA8 is connected to the first trigger terminal KA10; the other end of the normally closed delay-off contact KT3 is connected to the second trigger terminal and the third trigger terminal; the second trigger terminal is connected to the control terminal of the normally open delay-on contact KT4; the third trigger terminal is connected to the control terminals of the fourth normally open contact KA4 and the fifth normally open contact KA5; the other end of the normally open delay-on contact KT4 is connected to the fourth trigger terminal KA12; the other end of the third normally open contact KA3 is connected to one end of the fifth normally open contact KA5 and the other end of the sixth normally open contact KA6; the other end of the fifth normally open contact KA5 is connected to the fifth trigger terminal KA13 and the sixth trigger terminal KT2; the fifth trigger terminal KA13 is connected to the control terminals of the second normally closed contact KA8 and the sixth normally open contact KA6; the sixth trigger terminal KT2 is connected to the control terminal of the normally closed delay-off contact KT3.

[0078] Optionally, referring to Figure 3 , the coating control circuit further includes an overall output counting terminal C3 and a third normally closed contact KA9.

[0079] The other end of the first normally open contact KA1 is connected to the overall output counting terminal C3, the overall output counting terminal C3 is connected to one end of the third normally closed contact KA9, the other end of the third normally closed contact KA9 is connected to the film pasting input counting terminal C1 and the film pasting output counting terminal C2, and the fourth trigger terminal KA12 is connected to the control terminal of the third normally closed contact KA9.

[0080] Specifically, please refer to Figure 2 and Figure 4 together. The driving end A can be used to supply power to each module so that the corresponding module can operate when powered on; the film pasting input counting terminal C1 can detect the quantity of the parts to be pasted with film by means of the recognition device 8 at the entrance end of the film pasting machine 4, the film pasting output counting terminal C2 can detect the quantity of the parts to be pasted with film by means of the recognition device 8 at the exit end of the film pasting machine 46, and the overall output counting terminal C3 can detect the quantity of the parts to be pasted with film by means of the recognition device 8 at the exit end of the film pasting machine 46.

[0081] The signal transmission and control process in this embodiment is as follows:

[0082] After the system is powered on and running, the first normally open contact KA1 and the second normally open contact KA2 are closed. The film pasting input counting terminal C1, the film pasting output counting terminal C2, and the overall output counting terminal C3 are powered on and start to perform corresponding metering operations. The first trigger terminal KA10 is powered on and triggers the film pasting machine 4 to perform the film pasting operation. The second trigger terminal KT1 is powered on and triggers the normally open delay closing contact KT4 to close after a second preset time, so that the fourth trigger terminal KA12 is powered on and triggers the powder spraying machine 5 to stop the powder spraying operation. At the same time, the powered-on fourth trigger terminal KA12 triggers the third normally closed contact KA9 to disconnect, so as to prevent the overall output counting terminal C3 from outputting a reset signal to the film pasting input counting terminal C1 and the film pasting output counting terminal C2. At the same time, the third trigger terminal KA11 is powered on and triggers the fourth normally open contact KA4 and the fifth normally open contact KA5 to close, so that the first trigger terminal KA10, the second trigger terminal KT1, and the third trigger terminal KA11 maintain the powered-on state to achieve self-locking. When the number of workpieces to be film-pasted reaching the film pasting machine 4 entrance end counted by the film pasting input counting terminal C1 reaches the first metering value (specifically 1), the film pasting input counting terminal C1 triggers the first normally closed contact KA7 to disconnect. At this time, due to the self-locking effect of the fourth normally open contact KA4, the first trigger terminal KA10, the second trigger terminal KT1, and the third trigger terminal KA11 still maintain the powered-on state.

[0083] When the number of workpieces to be film-coated reaching the outlet end of the film coater 4 (i.e., the film coating operation is completed) counted by the film coating output counter C2 reaches the first measurement value (specifically 1), it indicates that the first workpiece to be film-coated has completed the film coating operation. Then, the film coating output counter C2 triggers the third normally open contact KA3 to close. Since the fifth normally open contact KA5 is also in the closed state at this time, the fifth trigger terminal KA13 and the sixth trigger terminal KT2 are energized. The fifth trigger terminal KA13 triggers the second normally closed contact KA8 to open, causing the first trigger terminal KA10 to lose power, thereby triggering the film coater 4 to stop the film coating operation. At the same time, the fifth trigger terminal KA13 triggers the sixth normally open contact KA6 to close, so that the fifth trigger terminal KA13 and the sixth trigger terminal KT2 remain energized after the third normally open contact KA3 is disconnected (the signal for the film coating output counter C2 to trigger the third normally open contact KA3 to close is a pulse signal, and the pulse signal causes the third normally open contact KA3 to return to the open state after a short closure), realizing self-locking. The sixth trigger terminal KT2 triggers the normally closed delay-off contact KT3 to open after the first preset time, causing the second trigger terminal KT1 to lose power, thereby triggering the normally open delay-on contact KT4 to open, causing the fourth trigger terminal KA12 to lose power and triggering the powder sprayer 5 to start performing the powder spraying operation. At the same time, the powered-off fourth trigger terminal KA12 triggers the third normally closed contact KA9 to close. The third trigger terminal KA11 loses power and triggers the fourth normally open contact KA4 and the fifth normally open contact KA5 to open, to release the self-locking function of the fourth normally open contact KA4, and to de-energize the fifth trigger terminal KA13 and the sixth trigger terminal KT2. The powered-off fifth trigger terminal KA13 will trigger the second normally closed contact KA8 to close. Since the fourth normally open contact KA4 has been disconnected at this time, the first trigger terminal KA10 cannot be energized, and thus the film coater 4 cannot be triggered to perform the film coating operation. At the same time, the powered-off fifth trigger terminal KA13 will trigger the sixth normally open contact KA6 to open, to release the self-locking function of the sixth normally open contact KA6. The powered-off sixth trigger terminal KT2 will trigger the normally closed delay-off contact KT3 to close. Since the fourth normally open contact KA4 has been disconnected at this time, the second trigger terminal KT1 cannot be energized, and thus the powder sprayer 5 cannot be triggered to stop the powder spraying operation. After the above communication process is completed, the film coater 4 will remain in the closed state, and the powder sprayer 5 will continue to perform the powder spraying operation to spray the remaining workpieces to be coated after the first workpiece to be coated, while avoiding the film coater 4 from mistakenly film-coating the remaining workpieces to be coated after the first workpiece to be coated. And the overall output counter C3 will continuously count the number of workpieces to be coated reaching the outlet end of the film coater 4.

[0084] When the last piece of the batch of workpieces to be coated reaches the outlet end of the film laminating machine 4, the number of workpieces to be coated counted by the overall output counting terminal C3 reaches the second measurement value (specifically, the total number of the batch of workpieces to be coated). At this time, the overall output counting terminal C3 outputs a reset signal through the branch where the third normally closed contact KA9 is located, so as to trigger the film laminating input counting terminal C1 and the film laminating output counting terminal C2 to perform a reset operation, and clear the counted number of workpieces to be coated (specifically, 1); at the same time, the overall output counting terminal C3 itself is also triggered to perform a reset operation, and clear the counted number of workpieces to be coated (specifically, the total number of the batch of workpieces to be coated). When the film laminating input counting terminal C1 performs a reset operation, the film laminating input counting terminal C1 will trigger the first normally closed contact KA7 to close, and at this time, the coating control circuit will return to the initial state. When the first piece of the next batch of workpieces to be coated reaches the inlet end of the film laminating machine 4 and is detected by the film laminating input counting terminal C1, the coating control circuit will repeat the above signal transmission and control process to perform corresponding film laminating operations and powder spraying operations on the next batch of workpieces to be coated; and so on in a cycle until all batches of workpieces to be coated have completed the film laminating operation and the powder spraying operation.

[0085] Correspondingly, please refer to Figure 1 and Figure 4 , the embodiment of the present invention further provides a coating device, which includes a film laminating machine 4, a powder spraying machine 5, a conveying device 7, an identification device 8, and the coating control circuit in any one of the above embodiments.

The identification device 8 can adopt a photosensitive sensor to directly measure the number of workpieces to be coated; the identification device 8 can also perform a timing operation by means of a timer. When the moving speed of the workpiece to be coated remains unchanged, the time for each workpiece to pass through the preset area is equal. Therefore, the number of workpieces to be coated passing through the preset area can be determined according to the time measured by the timer; in the specific implementation process, the identification device 8 can adopt a counting method, a timing method or other metering methods to cooperate with the metering circuit 1 to complete the counting of the number of workpieces to be coated, which is not limited here.

[0088] Through the above identification device 8, it can ensure the smooth progress of the metering operation of the metering circuit 1 on the workpiece to be coated, so as to ensure that the coating control circuit can trigger the film laminating machine 4 and the powder spraying machine 5 to perform corresponding start-stop actions according to the preset process in the above embodiment.

[0090] Optionally, referring to Figure 1 and Figure 4 , the conveying device 7 includes a first conveying section 701 and a prompting device (not shown in the figure); the output end of the first conveying section 701 is communicated with the inlet end of the film laminating machine 4; a first sensor 7011 is provided at the input end of the first conveying section 701, and a second sensor 7012 is provided at the output end of the first conveying section 701; the first sensor 7011 and the second sensor 7012 are connected to the prompting device; the first sensor 7011 is used to output a first in-place signal to the prompting device when detecting a workpiece to be coated, and the second sensor 7012 is used to output a second in-place signal to the prompting device when detecting a workpiece to be coated, and the prompting device is used to perform an abnormal prompting operation when receiving two first in-place signals continuously.

[0091] Optionally, referring to Figure 1 and Figure 4 , the conveying device 7 includes a second conveying section 702 and a prompting device (not shown in the figure); the input end of the second conveying section 702 is communicated with the outlet end of the film laminating machine 4, and the output end of the second conveying section 702 is communicated with the inlet end of the powder spraying machine 5; a third sensor 7021 is provided at the input end of the second conveying section 702, and a fourth sensor 7022 is provided at the output end of the second conveying section 702; the third sensor 7021 and the fourth sensor 7022 are connected to the prompting device; the third sensor 7021 is used to output a third in-place signal to the prompting device when detecting a workpiece to be coated, and the fourth sensor 7022 is used to output a fourth in-place signal to the prompting device when detecting a workpiece to be coated, and the prompting device is used to perform an abnormal prompting operation when receiving two third in-place signals continuously.

[0092] Optionally, referring to Figure 1 and Figure 4 , the conveying device 7 includes a third conveying section 703 and a prompting device (not shown in the figure); the input end of the third conveying section 703 is communicated with the outlet end of the powder spraying machine 5; a fifth sensor 7031 is provided at the input end of the third conveying section 703, and a sixth sensor 7032 is provided at the output end of the third conveying section 703; the fifth sensor 7031 and the sixth sensor 7032 are connected to the prompting device; the fifth sensor 7031 is used to output a fifth in-place signal to the prompting device when detecting a workpiece to be coated, and the sixth sensor 7032 is used to output a sixth in-place signal to the prompting device when detecting a workpiece to be coated, and the prompting device is used to perform an abnormal prompting operation when receiving two fifth in-place signals continuously.

[0093] In this embodiment, the conveying device 7 is divided into three sequentially connected conveying segments. In the first conveying segment 701, through the cooperation between the first sensor 7011 and the second sensor 7012, after a piece of work-piece to be coated is input at the input end of the first conveying segment 701, before this work-piece to be coated is output from the output end of the first conveying segment 701, it can be ensured that no other piece of work-piece to be coated is input from the input end of the first conveying segment 701, that is, it is ensured that only one piece of work-piece to be coated exists in the first conveying segment 701. Under normal operating conditions, the prompting device should alternately receive the first in-place signal and the second in-place signal; when the prompting device continuously receives two first in-place signals, it indicates that before the work-piece to be coated that has entered the first conveying segment 701 leaves the first conveying segment 701, another piece of work-piece to be coated enters the first conveying segment 701 and is detected by the first sensor 7011. At this time, it can be determined that the equipment is abnormal, and the prompting device can remind the operator to intervene in time by performing an abnormal prompting operation, or directly trigger the conveying device 7 and the corresponding equipment to stop running by performing an abnormal prompting operation, so as to avoid damaging the normal production process of the work-piece to be coated due to the disorder of the action rhythm.

[0094] Similarly, in the second conveying segment 702, through the cooperation between the third sensor 7021 and the fourth sensor 7022, after a piece of work-piece to be coated is input at the input end of the second conveying segment 702, before this work-piece to be coated is output from the output end of the second conveying segment 702, it can be ensured that no other piece of work-piece to be coated is input from the input end of the second conveying segment 702, that is, it is ensured that only one piece of work-piece to be coated exists in the second conveying segment 702. Under normal operating conditions, the prompting device should alternately receive the third in-place signal and the fourth in-place signal; when the prompting device continuously receives two third in-place signals, it indicates that before the work-piece to be coated that has entered the second conveying segment 702 leaves the second conveying segment 702, another piece of work-piece to be coated enters the second conveying segment 702 and is detected by the third sensor 7021. At this time, it can be determined that the equipment is abnormal, and the prompting device can remind the operator to intervene in time by performing an abnormal prompting operation, or directly trigger the conveying device 7 and the corresponding equipment to stop running by performing an abnormal prompting operation, so as to avoid damaging the normal production process of the work-piece to be coated due to the disorder of the action rhythm.

[0095] Similarly, in the third transfer section 703, through the cooperation between the fifth sensor 7031 and the sixth sensor 7032, after a piece of work-piece to be coated is input at the input end of the third transfer section 703, before the work-piece to be coated is output from the output end of the third transfer section 703, it can be ensured that no other piece of work-piece to be coated is input from the input end of the third transfer section 703, that is, it is ensured that only one piece of work-piece to be coated exists in the third transfer section 703. Under normal operating conditions, the prompting device should alternately receive the fifth in-place signal and the sixth in-place signal; when the prompting device continuously receives two fifth in-place signals, it means that before the work-piece to be coated that has entered the third transfer section 703 leaves the third transfer section 703, another piece of work-piece to be coated enters the third transfer section 703 and is detected by the fifth sensor 7031. At this time, it can be determined that the device is abnormal, and the prompting device can remind the operator to intervene in time by performing an abnormal prompt operation, or directly trigger the transfer device 7 and the corresponding equipment to stop running by performing an abnormal prompt operation, so as to avoid damaging the normal production process of the work-piece to be coated due to the disorder of the action rhythm.

[0096] Among them, the first sensor 7011, the second sensor 7012, the third sensor 7021, the fourth sensor 7022, the fifth sensor 7031 and the sixth sensor 7032 can adopt a kind of photoelectric sensor. The abnormal prompt operation can specifically be to send an alarm signal in the form of sound, image, etc., or to output an emergency stop signal to the transfer device 7 and the corresponding equipment.

[0097] Referring to Figure 7 , Figure 7 is a schematic structural diagram of a coating control system for the hardware operating environment involved in the embodiment solution of the present invention.

[0098] As Figure 7 shown, the coating control system may include: a processor, such as a central processing unit (CPU), a communication bus, a user interface, a network interface, and a memory.

[0099] Among them, the communication bus is used to realize the connection and communication between these components.

[0100] The user interface may include a display screen (Display), an input unit such as a keyboard (Keyboard), and the optional user interface may further include a standard wired interface and a wireless interface.

[0101] The network interface may optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (WIRELESS FIDELITY, WIFI) interface).

[0102] The memory can be a high-speed Random Access Memory (RAM), or a stable Non-Volatile Memory (NVM), such as a disk memory. Optionally, the memory can also be a storage device independent of the aforementioned processor.

[0103] Those skilled in the art can understand that Figure 7 the structure shown in does not constitute a limitation on the coating control system, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0104] As Figure 7 shown, the memory as a storage medium may include an operating system, a data storage module, a network communication module, a user interface module, and a coating control program.

[0105] In Figure 7 the coating control system shown, the network interface is mainly used to connect to the background server for data communication with the background server; the user interface is mainly used to connect to the client (user side) for data communication with the client; and the processor can be used to call the coating control program stored in the memory and execute the operations in the coating control method in any of the following embodiments.

[0106] Referring to Figure 1 、 Figure 4 and Figure 5 ,the embodiments of the present invention further provide a coating control method, which is applied to a coating device. The coating device includes a film laminating machine 4, a powder spraying machine 5, and a conveying device 7; the conveying device 7 is used to sequentially convey the workpiece to be coated to the film laminating machine 4 and the powder spraying machine 5.

[0107] The coating control method includes the following steps:

[0108] S1, perform a metering operation after reset; the metering operation refers to a timing operation or a count of the number of workpieces to be coated passing through the film laminating machine 4;

[0109] S2, turn on the film laminating machine 4 and turn off the powder spraying machine 5 to perform a film laminating operation on the workpiece to be coated passing through the film laminating machine 4;

[0110] S3, when the metering operation reaches a first metering value, turn off the film laminating machine 4 and turn on the powder spraying machine 5 to perform a powder spraying operation on the workpiece to be coated passing through the powder spraying machine 5; the first metering value is a time threshold or a numerical threshold;

[0111] S4, when the metering operation reaches a second metering value, repeat steps S1 - S3; the second metering value is a time threshold or a numerical threshold, and the second metering value is greater than the first metering value.

[0112] In this embodiment, the metering operation can be implemented by the metering circuit 1. The metering circuit 1 can count the number of workpieces to be coated by direct metering or indirect metering. When the direct metering method is adopted, the metering circuit 1 can directly measure the number of workpieces to be coated with the help of an identification device 8 such as a photosensitive sensor. At this time, the first metering value and the second metering value are numerical thresholds. The first metering value is the number of workpieces to be coated that need to be film-coated in each batch of workpieces to be coated, and the second metering value is the total number of workpieces to be coated in each batch. When the indirect metering method is adopted, the metering circuit 1 can perform a timing operation with the help of a timer. When the moving speed of the workpieces to be coated remains unchanged, the time for each workpiece to pass through the preset area is equal. Therefore, the number of workpieces passing through the preset area can be determined according to the time measured by the timer. At this time, the first metering value and the second metering value are time thresholds. The first metering value is the time required for several workpieces to be coated that need to be film-coated in each batch of workpieces to be coated to pass through the preset area, and the second metering value is the time required for all workpieces to be coated in each batch of workpieces to be coated to pass through the preset area.

[0113] The coating control method of this embodiment can be implemented based on the coating control circuit in the above embodiment, and its specific working process is as follows:

[0114] Taking the workpiece to be coated as glass as an example, in the actual coating process, multiple pieces of glass can be sequentially placed on the conveying device 7, and the multiple pieces of glass are arranged in a straight line from front to back. The film laminating machine 4 and the powder spraying machine 5 are arranged at intervals along the conveying direction of the conveying device 7, and each piece of glass is driven by the conveying device 7 to pass through the film laminating machine 4 and the powder spraying machine 5 in turn. Since the coating process for glass usually involves film-coating the first piece of glass in each batch of glass, and powder spraying the remaining glass, when the number of glass pieces in each batch is 10, the metering circuit 1 can adopt the direct metering method to count the number of glass pieces passing through the film laminating machine 4, and set the first metering value to 1 and the second metering value to 10.

[0115] In the first stage, that is, before the first piece of the first batch of glass reaches the film laminating machine 4, the device is powered on, triggering the main control circuit 3 to output a film-coating start signal through the first output terminal, and the film laminating machine 4 is turned on and enters the working state to perform a film-coating operation on the first piece of glass passing through the film laminating machine 4;

[0116] In the second stage, the first piece of glass has completely passed through the film laminating machine 4 and completed the film laminating operation. After the metering circuit 1 recognizes this piece of glass, the metering value becomes 1. At this time, the metering value of the metering circuit 1 reaches the first metering value. The metering circuit 1 outputs a first metering signal, triggering the main control circuit 3 to output a powder spraying start signal through the second output terminal and stop outputting the film laminating start signal through the first output terminal, so that the film laminating machine 4 is turned off, the powder spraying machine 5 is turned on and enters the working state. Thus, when the 9 pieces of glass after the first piece of glass pass through the film laminating machine 4, the film laminating machine 4 will not perform the film laminating operation on these 9 pieces of glass; and when the 9 pieces of glass after the first piece of glass pass through the powder spraying machine 5, the powder spraying machine 5 will perform the powder spraying operation on these 9 pieces of glass. During this process, the metering circuit 1 will continuously count the number of glasses passing through the film laminating machine 4.

[0117] In the third stage, when all 10 pieces of glass in this batch have passed through the film laminating machine 4, the metering value of the metering circuit 1 reaches the second metering value. The metering circuit 1 outputs a second metering signal, triggering the reset circuit 2 to perform a reset operation on the metering circuit 1, and at the same time triggering the main control circuit 3 to output a film laminating start signal through the first output terminal and stop outputting the powder spraying start signal through the second output terminal, so that the powder spraying machine 5 is turned off, the film laminating machine 4 is turned on and enters the working state. Thus, when the first piece of glass in the next batch of glass passes through the film laminating machine 4, the film laminating machine 4 will perform the film laminating operation on this first piece of glass; and when the first piece of glass in the next batch of glass passes through the powder spraying machine 5, the powder spraying machine 5 will not perform the powder spraying operation on this first piece of glass. During this process, the reset metering circuit 1 will start counting the number of glasses passing through the film laminating machine 4 from zero again. When the metering value of the metering circuit 1 reaches the first metering value again, the metering circuit 1 will output the first metering signal again and trigger the main control circuit 3 to perform the corresponding operation; and when the metering value of the metering circuit 1 reaches the second metering value again, the metering circuit 1 will output the second metering signal again and trigger the reset circuit 2 and the main control circuit 3 to perform the corresponding operations.

[0118] Based on the above cyclic process, the corresponding film laminating operation and powder spraying operation can be automatically performed on each batch of glass passing through the film laminating machine 4 and the powder spraying machine 5 in turn according to the preset coating operation rules (the first piece of glass in each batch of glass is subjected to the film laminating operation, and the remaining glass is subjected to the powder spraying operation) until the film laminating operation and the powder spraying operation on all batches of glass are completed.

[0119] Optionally, referring to Figure 2 、 Figure 4 and Figure 5 , step S3 includes:

[0120] S31, when the metering operation reaches the first metering value, turn off the film laminating machine 4, and turn on the powder spraying machine 5 after the first preset time to perform the powder spraying operation on the parts to be coated passing through the powder spraying machine 5.

[0121] In actual operation, the identification device 8 at the outlet of the film laminating machine 4 is usually used in conjunction with the metering circuit 1 in the above embodiment to perform metering operations on the parts to be coated. Based on this method, taking the example that the first part in each batch of parts to be coated needs to be coated and the rest need to be powder-sprayed, when the first part to be coated has completely passed through the film laminating machine 4 and is identified by the identification device 8 at the outlet of the film laminating machine 4 and the metering operation reaches the first metering value, the first part to be coated has not passed through the powder sprayer 5. At this time, if the powder sprayer 5 is immediately turned on to perform the powder spraying operation, the first part to be coated that has been coated may be mistakenly sprayed with powder, thereby destroying the coating production requirements.

[0122] Based on the above situation, in this embodiment, the film laminating machine 4 is immediately closed when the metering operation reaches the first metering value to ensure that the film laminating operation is stopped immediately after the first piece of each batch of parts to be coated is completed, thereby avoiding the accidental film laminating of the remaining parts to be coated after the first piece to be coated; at the same time, the powder sprayer 5 is turned on after a first preset time after the metering operation reaches the first metering value to ensure that the powder spraying operation is started after the first piece to be coated has completely passed through the powder sprayer 5, thereby avoiding the accidental powder spraying of the first piece to be coated.

[0123] The above delay control process can be implemented by means of the delay circuit 6 in the above embodiment and other delay circuits 6 (such as capacitor delay circuit 6, relay delay circuit 6, etc.). The first preset time can be set according to the conveying speed of the conveyor 7 to be the time required from the first piece to be coated leaving the film laminating machine 4 to the time the piece to be coated completely passes through the powder spraying machine 5.

[0124] Optionally, refer to Figure 2 , Figure 4 and Figure 5 , step S2 comprises:

[0125] S21 , starting the film laminating machine 4 , and closing the powder sprayer 5 after a second preset time, so as to perform a film laminating operation on the part to be coated passing through the film laminating machine 4 .

[0126] In the actual operation process, taking the example that the first piece in each batch of parts to be coated needs to be film-laminated and the rest need to be powder-sprayed, after the last piece of the current batch of parts to be coated completes the powder-spraying operation, the first piece of the next batch of parts to be coated will continue to be film-laminated; the following situation may occur: while the first piece of the next batch of parts to be coated is undergoing the film-laminated operation at the film-laminated machine 4, the last piece of the previous batch of parts to be coated is still undergoing the powder-spraying operation at the powder-spraying machine 5.

[0127] Based on the above situation, in this embodiment, the film pasting machine 4 is immediately started when the metering operation reaches the second metering value, so as to perform the film pasting operation on the first piece of the next batch of workpieces to be coated in time after the last piece of the previous batch of workpieces to be coated passes through the film pasting machine 4; at the same time, the powder spraying machine 5 is turned off after a second preset time after the metering operation reaches the second metering value, so as to ensure that the powder spraying operation is stopped after the last piece of the previous batch of workpieces to be coated completes the powder spraying operation.

[0128] The above delay control process can be implemented by means of the delay circuit 6 and other delay circuits 6 (such as capacitor delay circuit 6, relay delay circuit 6, etc.) in the above embodiment. Among them, the second preset time can be specifically set according to the conveying speed of the conveying device 7 as the time required for the last piece of the workpiece to be coated to leave the film pasting machine 4 until the workpiece completely passes through the powder spraying machine 5.

[0133] A reset module 40, configured to control the metering module to reset when the metering operation reaches the second metering value; the second metering value is a time threshold or a numerical threshold, and the second metering value is greater than the first metering value.
