Description

The roller pressing type positioning assembly relies on upper and lower pressing rollers to clamp the copper-clad plate to achieve guiding, and the friction contact between the pressing rollers and the surface of the plate is easy to cause scratches, damage the integrity of the copper foil on the surface of the copper-clad plate, and affect the subsequent circuit etching precision, and the surface wear of the pressing rollers after long-term use will cause the positioning precision to continuously decrease, so the rollers need to be frequently replaced, and the maintenance cost is high.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical scheme and advantages of the present application clearer and more apparent, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0034] Example one, as Figure 1 , the designed continuous transmission and rectification device for copper-clad plate mainly includes support 1, guide roller frame 2, upstream roller 2021, rectification roller 2011, downstream roller 2031, guide ring 204, industrial vision probe 4, electrically controlled airflow device 3, first motor 6, transmission assembly 7, and gas supply device, and each component cooperates to realize continuous transmission and accurate rectification of the copper-clad plate 5. The specific structural configuration is as follows:

[0035] As Figure 1 , Figure 2 , Figure 6 , the support 1 is used as the basic support component of the device, and is used for bearing all upper structures such as the guide roller frame 2 and the electrically controlled airflow device 3, so as to ensure the overall stability of the device. The mounting bracket 101 is arranged on the support 1, the mounting bracket 101 is matched with the mounting groove 303 at the bottom of the electrically controlled airflow device 3, the electrically controlled airflow device 3 is fixed on the mounting bracket 101 through the locking member 304, and the detachable installation of the electrically controlled airflow device 3 is realized, so as to facilitate the later maintenance and position adjustment.

[0036] As Figure 1 , Figure 3 , the guide roller frame 2 is fixed on the upper side of the support 1, and provides mounting support for the upstream roller 2021, the rectification roller 2011 and the downstream roller 2031. The guide roller frame 2 is divided into three functional areas, namely the upstream conduction area 202, the rectification area 201 and the downstream conduction area 203. The three areas are distributed in sequence along the conduction direction of the copper-clad plate 5, so as to ensure the order of the transmission path of the copper-clad plate 5.

[0037] As Figure 1 , Figure 3 , the upstream conduction area 202 is located upstream of the deviation correction area 201, and the upstream conduction area 202 is configured with a plurality of upstream rollers 2021. The main function of the upstream rollers 2021 is to stably convey the copper-clad plate 5 to the deviation correction area 201, and to provide initial transmission power and guidance for the copper-clad plate 5. The spacing between adjacent upstream rollers 2021 is the same, which ensures that the copper-clad plate 5 is uniformly stressed during transmission.

[0038] As Figure 1 , Figure 3 , the deviation correction area 201 is located between the upstream conduction area 202 and the downstream conduction area 203, and is the core area of the position correction of the copper-clad plate 5. The deviation correction area 201 is configured with a plurality of deviation correction rollers 2011. Taking the conduction direction of the copper-clad plate 5 as the reference, the span size of the deviation correction area 201 is smaller than the length size of the copper-clad plate 5, the spacing between adjacent deviation correction rollers 2011 is the same, and the spacing between the last upstream roller 2021 and the first deviation correction roller 2011 and the spacing between the last deviation correction roller 2011 and the first downstream roller 2031 are the same, which ensures the smooth transmission of the copper-clad plate 5 at the junction of each area.

[0039] As Figure 1 , Figure 3 , the downstream conduction area 203 is located downstream of the deviation correction area 201 and is configured with a plurality of downstream rollers 2031 for stably conveying the copper-clad plate 5 after correction to the next processing procedure. The spacing between adjacent downstream rollers 2031 is the same, and the spacing between the rollers of the upstream conduction area 202 and the deviation correction area 201 is consistent, ensuring that the transmission path of the copper-clad plate 5 is coherent and stable.

[0040] As Figure 2 , Figure 3 , Figure 4 , the deviation correction roller 2011, the upstream roller 2021 and the downstream roller 2031 are provided with a guide ring 204 on the side of the ring. The guide ring 204 is in frictional contact with the copper-clad plate 5 and is used to guide the transmission direction of the copper-clad plate 5. The guide ring 204 on the side of the deviation correction roller 2011 is provided with a plurality of flow guide grooves 2041 on the side of the ring. The flow guide grooves 2041 are independently aligned with the air outlet channels 3021 on the air outlet nozzles 302 of the electrically controlled airflow device 3, which facilitates the accurate blowing of airflow into the flow guide grooves 2041 and realizes the accurate control of the friction force between the guide ring 204 and the copper-clad plate 5.

[0041] As Figure 1 , Figure 2 , Figure 3The to-be-measured gap 205 includes a region between adjacent correction rollers 2011 and a region between the tail correction roller 2011 and the first downstream roller 2031. The industrial vision probe 4 is arranged directly below the to-be-measured gap 205. The industrial vision probe 4 directly below the same to-be-measured gap 205 is located at an upstream position of the electrically-controlled airflow device 3, and the industrial vision probe 4 vertically upwardly detects a region not blocked by the correction roller 2011, for monitoring a position state of the copper-clad plate 5 at the to-be-measured gap 205 in real time, and obtaining a blocking signal and a blocking time node of the copper-clad plate 5 (in the present application, the industrial vision probe 4 is used to monitor the moving state of the copper-clad plate 5, but any kind of component or device that can monitor the moving state of the copper-clad plate 5, such as an infrared detection method, for example, an infrared photoelectric sensing module, all belong to the protection scope of the present application).

[0042] As shown in Figure 1 , Figure 3 , when the copper-clad plate 5 is transmitted to the to-be-measured gap 205, if the copper-clad plate 5 exists offset, the time when the industrial vision probes 4 at different positions detect the blocking signal of the copper-clad plate 5 will exist difference, and through the difference, the offset direction and the offset degree of the copper-clad plate 5 can be judged.

[0043] As shown in Figure 1 , Figure 2 , Figure 3 , the electrically-controlled airflow device 3 and the industrial vision probe 4 are independently aligned one by one and arranged directly below the to-be-measured gap 205, for adjusting the friction between the airflow guide ring 204 and the copper-clad plate 5 through the airflow, and then realizing the correction of the position of the copper-clad plate 5.

[0044] As shown in Figure 2 , Figure 4 , the electrically-controlled airflow device 3 includes an air outlet nozzle 302, the airflow direction of the air outlet nozzle 302 is tangent to the upper curved surface of the upstream side correction roller 2011, so as to ensure that the airflow blown out by the air outlet nozzle 302 can be blown into the flow guide groove 2041 of the guide ring 204 of the upstream side correction roller 2011. The air outlet nozzle 302 is provided with a plurality of air outlet channels 3021, the air outlet channels 3021 are independently aligned one by one with the flow guide grooves 2041, so as to ensure that the airflow accurately and evenly acts on the contact area of the guide ring 204 and the copper-clad plate 5.

[0045] As shown in Figure 6 , the electrically-controlled airflow device 3 is internally provided with an electrically-controlled airflow valve, and the air outlet rate can be adjusted through the electrically-controlled airflow valve. The electrically-controlled airflow device 3 is further provided with an airflow external interface 301, the airflow external interface 301 is connected with a gas supply device through an airflow pipeline, and the gas supply device provides a stable gas source for the electrically-controlled airflow device 3.

[0046] As shown in Figure 1 , Figure 2 , Figure 6The bottom of the electrically controlled airflow component 3 is provided with an installation groove 303, which is adapted to the mounting bracket 101 of the bracket 1. The electrically controlled airflow component 3 is fixed on the mounting bracket 101 by the locking component 304, so as to realize the stable installation and position adjustment of the electrically controlled airflow component 3.

[0047] like Figure 1 , Figure 3 The first motor 6 is connected to multiple correction rollers 2011, multiple upstream rollers 2021, and multiple downstream rollers 2031 via a transmission assembly 7, providing power for the rotation of each roller and ensuring that the upstream rollers 2021, correction rollers 2011, and downstream rollers 2031 rotate synchronously, thus achieving continuous transmission of the copper-clad laminate 5. The first motor 6 can adjust its output speed according to system instructions, thereby changing the rotation speed of the upstream rollers 2021, correction rollers 2011, and downstream rollers 2031 to adapt to the speed requirements of the copper-clad laminate 5 in different transmission stages (such as the correction stage and the normal transmission stage).

[0048] Example 2: This invention designs a continuous transmission correction method for copper-clad laminates, the specific steps of which are as follows:

[0049] (a) Initial transmission phase

[0050] Start the first motor 6. The first motor 6 drives multiple upstream rollers 2021, correction rollers 2011 and downstream rollers 2031 to rotate synchronously at the system's preset standard speed Vs through the transmission component 7.

[0051] The copper clad laminate 5 is placed on the upstream roller 2021 of the upstream transmission area 202. The upstream roller 2021 drives the copper clad laminate 5 to move toward the correction area 201 through the friction between the guide ring 204 and the copper clad laminate 5. The copper clad laminate 5 passes through the upstream roller 2021 and the correction roller 2011 in sequence, and is finally transmitted to the downstream transmission area 203.

[0052] (II) Offset Detection Stage

[0053] After the copper-clad laminate 5 passes the position of the correction roller 2011, it enters the area of ​​the test gap 205. The industrial vision probes 4 directly below the same test gap 205 begin to monitor the occlusion signal of the copper-clad laminate 5 in real time.

[0054] The system receives occlusion signals transmitted by each industrial vision probe 4 in real time. First, it identifies and obtains the position of the first industrial vision probe 4 that detects the occlusion signal of the copper-clad laminate 5. This position can preliminarily determine the leading offset side of the copper-clad laminate 5. At the same time, the system records the time nodes when each industrial vision probe 4 directly below the same gap to be measured 205 detects the occlusion signal of the copper-clad laminate 5, and calculates the maximum difference between these time nodes, which is denoted as Δt. The magnitude of Δt reflects the degree of offset of the copper-clad laminate 5. The larger the Δt, the more serious the offset of the copper-clad laminate 5.

[0055] (III) Airflow Correction Stage

[0056] Based on the detection results, the system controls the electrically controlled airflow component 3, which is aligned with the position of the first industrial vision probe 4 that detected the occlusion signal of the copper-clad laminate 5 in the same test gap 205, to open its built-in electrically controlled airflow valve. The air supply device delivers airflow to the electrically controlled airflow component 3 through the airflow pipeline and the external airflow interface 301. The airflow is blown into the guide groove 2041 of the guide ring 204 of the corresponding correction roller 2011 through the air outlet channel 3021 of the air outlet 302.

[0057] Since the airflow direction of the air outlet 302 is tangential to the upper curved surface of the upstream correction roller 2011, the airflow can precisely act on the contact position between the guide ring 204 and the copper clad laminate 5, thereby reducing the friction between the guide ring 204 and the copper clad laminate 5. It should be noted that the upstream roller 2021, the correction roller 2011, and the downstream roller 2031 are driven to rotate by the first motor 6, and then the friction between the guide ring 204 and the copper clad laminate 5 drives the copper clad laminate 5 to move. Reducing the friction between the guide ring 204 and the copper clad laminate 5 at this position will correspondingly reduce the forward movement power of the copper clad laminate 5 at this position, so that the transmission speed on the offset side of the copper clad laminate 5 slows down, while the non-offset side maintains the original transmission speed, thereby achieving the position correction of the copper clad laminate 5.

[0058] During the correction process, the system adjusts the outlet speed V of the electronically controlled airflow component 3 in real time according to the maximum time difference Δt. gas And the exhaust rate V gas It is positively correlated with the maximum time difference Δt (V gas ∝Δt). When Δt is large, it indicates that the copper-clad laminate 5 is severely offset, and the system increases V. gas This enhances the airflow's effect on reducing friction and accelerates the correction speed. As Δt gradually decreases, the system reduces V. gas To avoid the copper-clad laminate 5 shifting in the opposite direction due to excessive airflow.

[0059] (iv) Correction and speed control stage

[0060] When the time points at which the industrial vision probes 4 directly below the same test gap 205 detect the blocking signal of the copper-clad laminate 5 are the same or basically the same, that is, when Δt≈0, it indicates that the copper-clad laminate 5 has been restored to the correct transmission position. The system controls all the opened electronically controlled airflow components 3 to close their built-in electronically controlled airflow valves, stop the airflow output, and the correction process ends.

[0061] Throughout the offset detection and correction process, when any industrial vision probe 4 detects a signal indicating that the copper-clad laminate 5 is obstructing the path, the system immediately controls the first motor 6 to reduce its output speed. This, in turn, via the transmission assembly 7, reduces the speeds of the upstream roller 2021 and the correction roller 2011 to the system's preset minimum speed V. min(V s >V min ). The purpose of reducing the rotation speed is to slow down the transmission speed of the copper-clad plate 5, to provide more sufficient time for airflow correction, to improve correction accuracy, and to avoid untimely correction due to too fast transmission of the copper-clad plate 5 (to prevent the speed of the correction roller 2011 from being inconsistent with the speed of the downstream roller 2031, and to ensure that the downstream roller 2031 can quickly transmit the copper-clad plate 5 alone, when the copper-clad plate 5 is introduced to the upstream roller 2021, it is necessary to ensure that the previous copper-clad plate 5 has passed through and left the correction roller 2011).

[0062] When the copper-clad plate 5 is corrected and all industrial vision probes 4 do not detect the copper-clad plate 5 blocking signal (i.e., the copper-clad plate 5 completely leaves the gap 205 to be detected area and enters the downstream transmission area 203 to be stably transmitted), the system controls the first motor 6 to restore the output rotation speed, so that the rotation speed of the upstream roller 2021, the downstream roller 2031 and the correction roller 2011 rises to the standard rotation speed V s of the system, to ensure that the copper-clad plate 5 is transmitted to the next process at a normal speed.

[0063] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.

Step 2: The copper clad laminate (5) reaches the upstream roller (2021) of the upstream conduction area (202), and the upstream roller (2021) drives the copper clad laminate (5) to move towards the correction area (201); Step 3: When the copper-clad laminate (5) reaches the gap to be tested (205) of the correction area (201), the industrial vision probe (4) below the gap to be tested (205) is activated to monitor the occlusion signal of the copper-clad laminate (5) in real time. Step 4: The system receives signals transmitted by each industrial vision probe (4) in the same test gap (205), identifies and determines the position of the first industrial vision probe (4) in the same test gap (205) that detects an obstruction signal; Step 5: The system acquires the time points when each industrial vision probe (4) in the same gap to be measured (205) detects the occlusion signal, and calculates the maximum difference Δt between the acquired time points; Step 6: The system controls the opening of the electrically controlled airflow component (3) that is aligned with the first industrial vision probe (4) that detects the obstruction signal in the same gap (205) to be measured, and the airflow blows through the air outlet (302) to the guide ring (204) of the correction roller (2011); At the same time, the system adjusts the outlet speed V of the electronically controlled airflow component (3) in real time according to Δt. gas And V gas It is positively correlated with Δt; Step 7: When the time points at which the industrial vision probes (4) within the same test gap (205) detect the obstruction signal are the same or approximately the same, shut down all the electrically controlled airflow components (3) that have been turned on within the same test gap (205). Step 8: When any industrial vision probe (4) detects an obstruction signal, adjust the rotation speed of the upstream roller (2021) and the correction roller (2011) to reduce them to the preset minimum rotation speed V. min ; When no obstruction signal is detected by any of the industrial vision probes (4), the rotational speeds of the upstream roller (2021), the correction roller (2011), and the downstream roller (2031) are restored to the preset standard rotational speed V. s , where V s >V min .
