Background
In recent years, the rapid development of online quality detection technology greatly ensures the production quality of assembly line products, and achieves the effect of real-time monitoring of the quality of PCB products. However, due to the limitation of various field environmental factors, the existing detection technology cannot guarantee the absolute reliability of all detection results, so that the products with abnormal quality, which are partially intercepted by the on-line detection equipment, need to be subjected to secondary manual rechecking.
To realize the recheck function, the existing pipeline equipment needs to combine and apply various large-sized equipment with only a single function. The disadvantage of the combined application of various devices is the complexity, high investment cost and great occupation of the line length of the factory pipeline. In addition, the combined equipment does not have an automatic recognition function, so that a large number of repeated manual code scanning recognition operations are still needed, and great influence is generated on the layout of the production line and lean production.
Therefore, a multifunctional, highly integrated, miniaturized, and intelligent pipeline operation platform is needed to meet the demands of lean production.

Detailed Description
An integrated operation platform for a circuit board and an operation method for a circuit board according to the present invention will be described below with reference to the accompanying drawings and by means of preferred embodiments.
As shown in fig. 1, in a circuit board automated production line, such as a Printed Circuit Board (PCB) automated production line, an integrated operation platform 200 according to the present invention may be disposed between an upstream in-line inspection apparatus 100 and a downstream blanking machine 300.
The circuit board, for example, the PCB, may be conveyed in a left-to-right direction in fig. 1 via a conveying means, wherein the circuit board, which is judged by the in-line inspection apparatus 100 that the initial inspection result is of normal quality, is conveyed sequentially through the in-line inspection apparatus 100 and the integrated operation platform 200 and output to the blanking machine 300; the circuit board, the initial inspection result of which is judged to be abnormal in quality by the on-line inspection device 100, is reserved in the integrated operation platform 200 to be rechecked. The transfer device 203 may be a rail transfer device extending in a horizontal direction. The track transport may be equipped with a dual anti-misalignment position sensor to sense and send information from the circuit board that is being passed by the position sensor.
An integrated operating platform according to one embodiment of the present invention is described in detail below in conjunction with fig. 2a, 2b and 2 c.
In the embodiment shown in fig. 2a and 2b, the integrated operation platform comprises a first zone, indicated with 201, i.e. a scratch pad zone. The first area is used for storing at least one circuit board with initial abnormal detection. The first zone 201 may comprise a first support means for supporting the circuit board and a first drive means 212 for driving the first support means (see fig. 3b, in which the first drive means are obscured by the second drive means 222, so that the position of the first drive means 212 in the transverse direction of the operating platform, i.e. transverse to the conveying direction of the circuit board, is only schematically shown). Fig. 2a and 2b show a lifting support 211 as a first support means. The liftable support 211 has an unsupported position below the track transport surface and at least one supported position above the track transport surface. The liftable support 211 may be arranged at both sides of the track and may be provided with one or more sets of protrusions 213 for supporting the circuit board (see fig. 2 c), each protrusion 213 may protrude from the liftable support 211 towards one side of the circuit board transverse to the transport direction of the transport means, i.e. the transport direction of the circuit board. The same set of protrusions 213 are at the same height. If a plurality of sets of projections 213 are provided, the projections of the different sets are arranged at intervals in a direction substantially perpendicular to the conveying direction of the circuit boards, i.e., in the vertical direction, so that the liftable stand 211 can support a plurality of circuit boards, for example, 3 to 8 circuit boards.
When the liftable stand 211 is not used to support the circuit board, the liftable stand 211 is kept in the non-supporting position, and since the non-supporting position is lower than the track conveying surface and the stand is located inside the track side in the track width direction (in other words, the distance between the stands located on both sides of the track, which is transverse to the conveying direction of the circuit board, is larger than the track width), interference is not caused to the conveying device, and normal conveyance of the circuit board is not affected. When the circuit board needs to be stored in the first area 201, the liftable stand 211 is lifted to the supporting position. When the liftable support 211 is provided with a plurality of sets of protrusions 213, the liftable support 211 has a plurality of supporting positions having different heights accordingly.
In addition, the integrated console also includes a second zone, i.e., a review zone, indicated at 202. The second zone includes a review station capable of storing at least one initially abnormal circuit board for review thereof.
The second region 202 may include a second supporting means for supporting the circuit board and a second driving means 222 for driving the second supporting means. Fig. 2a and 2b show a lifting support 221 as a second supporting means. Similar to the liftable support 211, the liftable support 221 also has an unsupported position below the track transport surface and at least one supported position above the track transport surface. The liftable support 221 may be arranged at both sides of the track and may be provided with one or more sets of protrusions 223 (see fig. 2 c) for supporting the circuit board, each protrusion 223 may protrude from the support 221 towards one side of the circuit board transverse to the circuit board transport direction. The same set of protrusions 223 are substantially at the same height.
Preferably, the liftable support 221 of the second area 202 is provided with a set of protrusions 223 so that 1 circuit board to be rechecked can be stored in the second area 202. Such an arrangement facilitates the re-inspection operation in a very simple and efficient manner. For example, when the operator finds that the liftable support 221 of the second area 202 supports the circuit board of the initial inspection abnormality to rise, the operator may perform a re-inspection operation thereon and input a re-inspection result to the operation platform. The lifting support 221 of the second zone 202 then descends supporting the circuit board for which the reinspection is completed to transport it to the corresponding output device downstream.
Alternatively, a plurality of sets of the projections 223 may be provided, with the projections 223 of different sets being arranged at intervals in a direction substantially perpendicular to the conveying direction of the circuit boards, i.e., in the vertical direction, so that the liftable support 221 can support a plurality of circuit boards, for example, 2 or 3 circuit boards. In this case, the liftable support of the second zone supports the respective circuit board for which the reinspection is completed, so that it returns to the track transport surface and is transported to the respective output device downstream.
When there is no circuit board for initial inspection abnormality and thus there is no need to support the circuit board using the liftable stand 221, the liftable stand 221 is kept in the unsupported position, and since the unsupported position is lower than the rail transfer surface and the stand is located inside the rail side face in the rail width direction (in other words, the distance between the stands located on both sides of the rail, which is transverse to the circuit board transfer direction, is larger than the rail width), there is no interference with the transfer device and normal transfer of the circuit board is not affected. When the circuit board to be retested is to be placed in the retesting station of the second zone 202, the liftable support 221 is lifted to the supporting position. When the liftable support 221 is provided with a plurality of sets of protrusions 223, the liftable support 221 has a plurality of supporting positions with different heights accordingly.
In a preferred embodiment, the first area 201 is disposed upstream of the second area 202 in the integrated operation platform 200, so that it is advantageous to transfer the circuit board with the initial inspection abnormality temporarily stored in the first area 201 to the second area 202 for re-inspection via the transfer device after all re-inspection of the circuit board with the initial inspection abnormality stored in the second area 202 is completed. The first area 201 stores the circuit board with abnormal initial inspection only when the circuit board which has not been re-inspected is stored in the second area 202. The maximum number of circuit boards that have not been rechecked as described above may be in the range of 1 to 3.
In the embodiment shown in fig. 2a and 2b, the operating platform is pre-reserved for mounting the scanning device for docking.
In another preferred embodiment, shown in fig. 3a and 3b, the review station may include a scanning device 205 and a PLC controller (not shown). The PLC controller may control the scanning device 205 to automatically read the bar code of the circuit board and transmit the read information to the computer 206. In this embodiment, the computer is built into the operating platform. It is contemplated that the computer may also be located external to the operating platform. The computer can access the detection data of the upstream detection equipment through the enterprise internal network so that an operator can carry out manual recheck according to the error reporting information. The scanning device 205 may also be configured to be liftable and lowerable, thereby expanding the scanning range.
As shown in fig. 3a and 3b, the integrated operation platform may further comprise an alarm device 207 for emitting an alarm signal after the initial abnormal circuit board stored in the first area 201 reaches a predetermined first maximum number. As previously mentioned, the first maximum number may be in the range of 3 to 8.
In addition, the operation platform can be further provided with a display screen 204, through which an operator can monitor error information and acquire upstream primary inspection data of the circuit board to be rechecked.
According to the preferred embodiment shown in fig. 3a and 3b, the operator can perform the review operation through the touch screen 208 and input the review result through the review result confirmation key 209.
In a preferred embodiment of the invention, the rail may be equipped with a dual anti-misalignment position sensor. In addition, the circuit board may be provided with a dust-proof protection cover made of transparent antistatic material. In addition, the operator may be provided with a work instruction manual cradle and/or a cradle 210 for housing an instruction input device such as a mouse, a keyboard, or the like, and a visual inspection auxiliary lighting device whose brightness is freely adjustable.
In a preferred embodiment of the invention, the first drive means and/or the second drive means may comprise an electric motor and a screw. In another preferred embodiment, the first drive means and/or the second drive means may comprise a cylinder.

(2) If the upstream online detection equipment outputs a product with abnormal quality, the operation platform sends the product to a second area, namely a rechecking area; in order not to influence normal transmission of the production line products, the second area is lifted, and meanwhile, the lifting operation triggers a bar code scanning signal, so that the PLC controller controls the scanning device to automatically read the bar codes of the products and send the bar codes to the reinspection computer, the computer invokes upstream detection data through an enterprise internal network, and an operator carries out manual reinspection judgment according to error reporting information.
(3) The operator inputs a recheck result to the operation platform through a key, if the manual recheck result is qualified, the second area automatically descends, the second area outputs an OK signal downstream, and the product is transmitted to a downstream blanking machine; if the result of the manual recheck is that the second area is unqualified, the second area automatically descends, and the second area outputs NOK signals downstream and transmits the products to a downstream blanking machine.
(4) When the upstream detection equipment continuously outputs products with abnormal quality, if the second area, namely the rechecking area, has products to be rechecked which are not processed in time, the first area, namely the temporary storage area, can automatically rise layer by layer to temporarily store the products to be rechecked in order to avoid the blockage of the assembly line; when the product to be detected is stored in the first area, in order to avoid the occurrence of assembly line congestion, the operation platform can automatically send out an audible and visual alarm signal through the alarm device to remind on-site workers of checking the assembly line state in time.
2. Sequential sequence processing mode:
(1) If the product output by the on-line detection equipment is normal in quality, the operating platform outputs an OK signal to the downstream, and directly outputs the product to the downstream blanking machine.
(2) If the product output by the on-line detection device is a product with abnormal quality, the operation platform sends the product to a second area, namely a rechecking area, the second area is lifted in order not to influence the normal transmission of the production line product, and the lifting operation triggers the following operations: and sending a corresponding information calling instruction to the serial port of the reinspection computer, calling upstream detection data by the computer through an enterprise internal network, and performing manual reinspection judgment by an operator according to the error reporting information.
(3) The operator inputs a recheck result to the operation platform, if the manual recheck result is qualified, the second area automatically descends, and the second area outputs an OK signal downstream and transmits the product to a downstream blanking machine; if the result of the manual review is not qualified, the second area automatically descends, and the second area outputs NOK signals downstream and transmits the products to a downstream blanking machine.
(4) When the upstream detection equipment continuously outputs products with abnormal quality, if the second area, namely the rechecking area, has products to be rechecked which are not processed in time, the first area, namely the temporary storage area, can automatically rise layer by layer to temporarily store the products to be rechecked in order to avoid the blockage of the assembly line; when the first area is full of products to be detected, in order to avoid the occurrence of assembly line congestion, an alarm device of the operation platform can automatically send out an audible and visual alarm signal to remind on-site workers to check the assembly line state in time.
