The development of circuit boards is towards light weight, miniaturization and portability, and the development of PCBs towards higher density and multilayer boards is promoted: in order to ensure the processing quality of the circuit boards, each batch and each circuit board processing device need to execute a first piece detection flow so as to control the processing quality. Such first-piece detection includes, but is not limited to: X-Ray inspection, hole site inspection, blind hole defect detection, back drilling defect detection, blind hole depth measurement, back drilling depth measurement and other detection procedures.
For first part detection, taking hole position detection as an example, if hole position precision self-moving detection equipment is used for replacing earliest manual detection of hole position precision, especially, accurate and efficient detection is carried out on the drilling precision of a micro through hole or a micro blind hole, problems are found in the stage of mechanical drilling or UV laser drilling, the drilling process quality and the production efficiency of a PCB can be improved, and the production cost is reduced. Through the machine vision imaging measurement technology, the deviation displacement of the actual position of the drilling hole relative to the theoretical position is automatically identified visually, and an operator can adjust the precision correction data of the circuit board processing equipment even through the expansion and contraction data output by the hole position precision measuring instrument, so that the drilling hole quality control precision is achieved again. Therefore, the first part detection is very important for the circuit board processing equipment.
For the self-moving detection equipment, the circuit board to be detected by the first part is often sourced from different time, different batches (different material numbers) and different circuit board processing equipment machine stations, so that the detection flow needs to be continuously adjusted according to the source of the circuit board to be detected, and the detection flow is completely dependent on manual work to carry out material transfer, detection, data recording and tracing on the product to be detected. In addition, a certain distance exists between a circuit board processing equipment workshop and a self-moving detection equipment workshop, and the circuit board to be detected is manually transferred to corresponding self-moving detection equipment (fixed type) for detection, so that the detection flow efficiency is low; in addition, the circuit board to be detected is transferred from one area to another area, the instant detection cannot be performed on the first site of the circuit board processing equipment, the change of the existing time, space, environment (temperature, humidity and other conditions) is very likely to cause the abnormal or swelling change of the circuit board to be detected, the authenticity of the detection result is affected, the detection result cannot be faithfully fed back or restored to the original processing parameter level of the circuit board processing equipment, and therefore, the higher processing quality requirement cannot be achieved through various debugging or compensation technical means.
In a word, from the aspect of accuracy of a detection result, the existing detection method and flow of the first piece of circuit board make it difficult to further optimize and improve the processing accuracy of circuit board processing equipment; meanwhile, the low-efficiency detection flow is also an obstacle point for cost reduction and synergy of lean operation factories, and a brand new detection method and equipment are urgently needed.
In view of this, it is necessary to design a precise, instant and efficient detection method, device and system for first-part detection for the workshop of the existing circuit board processing equipment, by which the inconsistency between the time waiting, the first-part material space transfer redundancy link and the working environment conditions of the two links of processing and detecting can be avoided or reduced, the accuracy and the reliability of the detection result can be improved, the efficiency of the detection flow can be improved, the better processing quality management and control can be achieved, and the goals of reducing cost and enhancing efficiency can be achieved.

In the above and below embodiments of the present invention, the first component refers to any one of the following circuit boards: the circuit board processing equipment processes a first circuit board of a certain batch, the circuit board processing equipment processes the circuit board for the first time, and after processing the preset time, the circuit board processing quality is checked and detected by spot check, and after processing the preset number of the circuit boards, the circuit board processing quality is checked and detected by spot check. The first part is not limited to the first circuit board, and further comprises a second circuit board for continuing the first part detection if the first circuit board is failed, and meanwhile comprises a circuit board for spot check. Because the circuit board processing equipment is processed in batches, the processing quality of each processed circuit board does not need to be detected, and in most cases, only spot check is needed to determine that the processing quality of the spot checked circuit board meets the requirement of the preset specification. Therefore, the spot check includes at least one of the above four cases, and in the process of spot checking the first part in practical application, a certain batch of circuit boards refer to the same material number, and the same processing program is used for processing, so that the spot check first part is required to verify the processing quality of the circuit board processing equipment.

Since the circuit board processing apparatus is 24 hours of repeated processing, although it is not necessary to check the quality of each circuit board processing apparatus, monitoring and spot check are necessary, and thus a circuit board is spot checked at a predetermined time, for example, 1 hour, for processing by the circuit board processing apparatus; or processing a predetermined number, such as 50 or 100 circuit boards, and performing spot check on one circuit board, wherein spot check in the processing process is one of the first detection contents, and the main purpose of the spot check is to timely monitor and verify the processing quality of the circuit board processing equipment.
In some embodiments of the present invention, after the first part processing task is executed by the control circuit board processing device, the first part processing task is executed by calling the self-movement detection device to move to be close to the circuit board processing device. Here, the first part detection tasks of different circuit board processing apparatuses are different, and different first part processing tasks may also have different first part detection tasks. Therefore, the upper computer scheduling control system needs to determine the self-movement detection equipment according to the first workpiece processing task. The first workpiece processing task may be drilling, edge milling, slicing, etc., and the corresponding self-moving detection equipment may be an optical hole position accuracy detection device, a forming size measurement device, an AOI detection device, etc. There are various types of self-moving detection devices, and it is necessary to determine which type of self-moving detection device is to perform a first-piece detection task according to a first-piece processing task. In an automated shop, according to the first part processing detection requirement, a plurality of types of self-movement detection devices are configured, and the self-movement detection devices execute a plurality of types of first part detection tasks of the circuit board processing device under the control of an upper computer dispatching control system. For example, when the circuit board processing device performs a first workpiece processing task of the back drill, the scheduling control system invokes the self-moving detection device carrying the AOI detection device matched with the first workpiece processing task to perform the first workpiece detection task. The matching relation is matched one by one according to the first processing task and is preset in the upper computer dispatching control system. After determining which self-moving detection device is used according to the first object processing task, under the control of the dispatching control system of the upper computer, the selected target self-moving detection device moves to be close to the circuit board processing device, and the target self-moving detection device calls the first object parameter to execute the first object detection task. The first object parameter is an application program which is selected by the scheduling control system on the target self-moving detection device according to the first detection task and used for executing the first detection task. The application program presets a plurality of kinds, and the target self-moving detection equipment selects one of the first object parameters to execute the first detection task according to the instruction of the dispatching control system.
In some embodiments of the present invention, because the circuit board processing apparatus inevitably generates a certain amount of impurity dust during the process of processing the circuit board, the impurity dust adheres to the surface of the circuit board, and the accuracy and precision of the first part detection are affected. Thus, the self-moving detection device further comprises cleaning the headpiece prior to performing the headpiece detection task. The motion chassis of the self-movement detection equipment is also provided with a third area adjacent to the first area, the third area is provided with a cleaning device, and the air flow output by the cleaning device cleans the impurity dust on the surface of the first part. The air flow blown by the cleaning device sweeps the surface of the first piece of the circuit board, and is used for removing residual miscellaneous dust in the process of processing the first piece of the circuit board processing equipment, so that the interference of the miscellaneous dust on the detection of the first piece of the circuit board processing equipment is reduced, and the detection accuracy is improved. The cleaning device is fixed on the self-moving detection equipment, and the first part is cleaned in the process of carrying the first part by the transfer device, so that the time can be saved, and the detection precision can be improved. In some preferred embodiments, the air outlet of the cleaning device is located in the path of the transfer device carrying the head piece, and the air flow of the air outlet sweeps the lower surface of the head piece. Meanwhile, in order to achieve a better cleaning effect, after the first piece is conveyed by the conveying device and passes through the air outlet of the cleaning device, the first piece is clamped by the conveying device to be overturned, the upper surface of the first piece is overturned to be aligned with the air outlet, and the air flow blown by the cleaning device cleans the upper surface of the first piece. The upper surface and the lower surface of the head piece are cleaned by the air flow of the cleaning device, so that the accuracy of detection is ensured, the detection time is not affected excessively, and the technical superiority of cleaning the head piece is reflected.
In some embodiments of the invention, the self-movement detection device further comprises adjusting levelness prior to performing the first piece detection task. The motion chassis of the self-moving detection equipment moves at a high speed, so that the levelness cannot be absolutely excellent, and once the levelness deviates, the abrasion is aggravated, and the levelness is further worsened. Therefore, on the premise that the levelness of the motion chassis cannot be guaranteed, the levelness of the detection device on the motion chassis is difficult to guarantee, the levelness of the detection device is unqualified, the first detection result is seriously affected, and the detection result is distorted. In order to solve the problem of detecting device's levelness, set up adjusting part between detecting device and motion chassis, adjusting part is used for adjusting detecting device's levelness. In some preferred embodiments of the present invention, the adjusting assembly includes a vibration isolation tray, the foot pad of the vibration isolation tray is automatically unfolded and ground contact starts to adaptively perform horizontal adjustment movement, and the control part generates a driving control signal to drive the moving part to horizontally adjust according to real-time detection of the horizontal offset by a horizontal detection module provided to the detection device. The levelness of the detection device is guaranteed by the adjusting component, so that the accuracy and the credibility of the first part detection of the self-moving detection equipment are improved.
In some embodiments of the invention, the transfer device transfers the first part from the circuit board processing apparatus to the self-movement detection apparatus prior to performing the first part detection task. The self-moving detection device comprises a transfer device in a first area, and the transfer device transfers the first part between the circuit board processing device and the self-moving detection device.

Under the control of the upper computer mobilizing control system, the circuit board processing equipment starts to process the first piece, the self-moving detection device moves to be close to the circuit board processing equipment, and after the positions and the identities of the two pieces of equipment are confirmed through communication with the circuit board processing equipment, the levelness of the detection device starts to be adjusted. After the preparation work is finished, the workbench of the circuit board processing equipment outputs the finished first piece of circuit board to the direction of the self-movement detection equipment through the buffer device or the manipulator, the transfer device picks up the first piece, and the cleaning device passes through the upper part of the cleaning device in the third area, and the cleaning device outputs air flow to the first piece to clean the impurity dust on the surface of the circuit board. The transfer device picks up the first part and continues to move until the first part circuit board is transferred to the detection device. The detection device comprises a visual part, a movement part and a control part, wherein the movement part is used for controlling the visual part to be aligned with the first part, the visual part is used for detecting characteristic parameters of the first part according to preset first object parameters, and the control part is used for judging whether the first part meets preset specification requirements according to detection results of the visual part. After the detection device detects the first part, the transfer device picks up the first part again and transfers the first part to a workbench of the circuit board processing equipment through the buffer device or the manipulator. So far, in the first part detection process, the transfer device transfers the first part between the circuit board processing equipment and the self-moving detection equipment, so that the automatic transfer of the first part is time-saving, and the first part detection efficiency is improved.

The detection device also comprises a control part, wherein the control part receives the detection result of the vision part and outputs a control information instruction. Specifically, when the detection result of the first part meets the preset specification requirement, sending control information of batch processing to the upper computer; and when the first piece does not meet the preset specification requirement, controlling the self-movement detection equipment to generate correction parameters. The control unit includes a judging unit, compares the first detection result with a preset specification parameter, and outputs different control information instructions based on the comparison result. If the parameter information of the first part detection result does not exceed the upper limit and the lower limit of the preset specification parameter, the judging unit judges that the first part detection is qualified, the control part sends control information of the qualified first part detection to the circuit board processing equipment, and the circuit board processing equipment sends a control information instruction of batch processing to the upper computer. If the parameter information of the first part detection result exceeds the upper limit and the lower limit of the preset specification parameter, the judging unit judges that the first part detection is unqualified, and when the first part detection result is unqualified, the control part calculates the compensation parameter based on the detection result and generates the correction parameter. Meanwhile, the control part of the self-movement detection equipment sends the correction parameters to the circuit board processing equipment, the circuit board processing equipment receives the correction parameters, the circuit board processing equipment comprises a second object parameter for processing the circuit board, and the circuit board processing equipment integrates the received correction parameters into the second object parameter to form a second characteristic parameter. Under the control of the dispatching control system, the circuit board processing equipment uses the second characteristic parameters to execute the first processing task again. And in the process of executing the first part processing task again, the first part processing task information is sent to the dispatching control system, the dispatching control system calls the self-moving transportation equipment to transfer the first part to the circuit board processing equipment, and the circuit board processing equipment calls the second characteristic parameter to execute the first part processing task again. After the first part is processed, the circuit board processing equipment transfers the first part to the self-moving detection equipment, receives the second processed first part from the self-moving detection equipment and executes the first part detection task. Of course, before the first member detection task is executed, cleaning the first member, adjusting the levelness of the detection device and the like are further included. Before the detection device executes the first part detection task, the self-moving detection device integrates the correction parameters into the first object parameters to form first characteristic parameters, and the self-moving detection device calls the first characteristic parameters to execute the first part detection task again. It should be noted that, after the correction parameters generated by the first-component detection task are integrated into the first object parameters, the first feature parameters are formed, and when the first-component detection task is executed for the second time, the first feature parameters are called, that is, the first object parameters are obtained by integrating the correction parameters. When the detection result of the first part of the second time meets the preset specification requirement, sending control information of batch processing to the circuit board processing equipment; and when the first piece does not meet the preset specification requirement, controlling the self-movement detection equipment to generate correction parameters again. So reciprocating, integrate the correction parameter at every turn into circuit board processing equipment and from the removal check out test set, constantly correct and compensate the deviation of first piece, improve circuit board processing equipment's machining precision to improve circuit board processing equipment and process the quality in batches.

The first workpiece is processed by the following working tasks:
s22, the circuit board processing equipment sends the first processing task requirement to the upper computer.
For the D12 circuit board processing apparatus, before performing the batch processing task of the P2 lot, the first part, referred to as the first circuit board, denoted B1, needs to be confirmed and checked to verify the processing quality. Therefore, after the second object parameter is called, the D12 circuit board processing device sends the requirement information of the first piece of processing to the M01 upper computer. After receiving the demand information of the first piece of processing of the D12, the upper computer M01 sends the demand information of the circuit board to the warehouse management system, and after receiving the demand information of the M01 circuit board, the warehouse management system inquires the inventory circuit board, and transmits the number of the inventory circuit board, and a material box for loading the B1 circuit board to a workstation.
S24, transferring the first part from the mobile conveying equipment to the circuit board processing equipment.
When the bin containing the B1 circuit board is loaded at the workstation S05, the upper computer M01 inquires the self-moving transportation device, and sends a control instruction for transporting the bin containing the B1 circuit board to the self-moving transportation device T04, and after the T04 receives a work task from the self-moving transportation device, the bin containing the B1 is moved to the workstation S05, and the bin containing the B1 is loaded and moved to be close to the D12 circuit board processing device. And transferring the B1 circuit board to a 03-type spindle. In this manner, the self-moving transport facility T04 completes the job task of transporting the first part B1 from the warehouse management system to the D12 circuit board processing facility. Here, the bin for loading B1 contains a plurality of circuit boards, for example, 18 boards, and a layer in which the B1 first board is located. Therefore, the time for transferring the circuit board can be saved, and the operation efficiency of an automatic workshop can be improved. In this embodiment, the B1 circuit board is transferred from the front side of the D12 circuit board to the No. 03 processing area of the D12 circuit board processing apparatus by the robot from the mode of performing the front loading by the mobile transport apparatus T04.
S26, processing the first part by using circuit board processing equipment.
The first part B1 is located in a 03 processing area of the D12 circuit board processing device, and the circuit board processing device D12 processes the B1 circuit board by a spindle assembly corresponding to the 03 processing area under the control of the second object parameters. And processing the B1 circuit board, namely drilling holes on the B1 circuit board one by one according to the rule of the second object parameter. Subsequent first part detection is directed to multiple hole sites on the B1 circuit board. It should be noted that, the B1 drilling process is performed according to the second object parameter, that is, the parameter of the P2 batch process, so that the actual situation of the subsequent batch process can be further restored, and the factor of disturbing the first workpiece is reduced. All parameters for batch processing of P2 batches of circuit boards were identical, including B1.
S40, calling the self-movement detection equipment to move to be close to the circuit board processing equipment, and executing the first part detection task;
after the processing equipment of the D12 circuit board finishes processing the B1, the D12 circuit board sends first detection task demand information to the upper computer MO1, the M01 upper computer calls the C03 self-movement detection equipment and sends detection task information to the C03 self-movement detection equipment, the C03 self-movement detection equipment receives the task information of the M01 upper computer, and the M01 self-movement detection equipment moves and approaches to the D12 circuit board processing equipment. Here, the circuit board processing device D12 and the second object parameter together determine the type of the C03 self-movement detection device, that is, the M01 upper computer determines the C03 self-movement detection device according to the first workpiece processing task. Different first-piece machining tasks are matched with different self-moving detection equipment, when the first-piece machining tasks are edge milling, the corresponding C04 self-moving detection equipment is called to execute the first-piece detection tasks, and when the first-piece machining tasks are back drilling, the corresponding C05 self-moving detection equipment is called to execute the first-piece detection tasks. The first workpiece detection tasks are not described in detail, and are not described in detail.
And C03 self-moving detection equipment is close to D12 circuit board processing equipment, and after the position and the identity of the self-moving detection equipment are confirmed through wireless communication, the D12 circuit board processing equipment transfers the first part B1 to the C03 self-moving detection equipment in a front blanking mode. Specifically, the D12 circuit board processing apparatus has a first part B1 in the No. 03 processing area, the table pushes B1 to the forefront side, and C03 picks up B1 from the table from the robot of the movement detecting apparatus. On the self-movement detection device C03, the manipulator picks up the air flow blown out by the cleaning device and cleans the upper and lower surfaces of the first member B1. The manipulator then B1 conveys the object to the moving part of the detection device. The motion part comprises a detection platform, and B1 is arranged on the detection platform. In order to ensure the precision of the detection platform, the levelness of the detection device needs to be adjusted before the first part is detected.
After the B1 circuit board is conveyed to the detection platform of the detection device, the adjustment assembly starts to adjust the levelness of the detection device. Specifically, the vibration isolation tray foot pads of the adjusting assembly are automatically unfolded and ground contact starts to adaptively perform leveling movement, the horizontal offset degree is detected in real time according to a horizontal detection module arranged on the detection platform, and the control part generates a driving control signal to drive the moving part to horizontally adjust. And when the levelness of the adjusting assembly adjusting detection platform meets the preset requirement, the levelness is adjusted to be finished. When the levelness of the adjusting assembly adjusting detection platform does not meet the preset requirement, the levelness adjustment is continuously carried out, and the levelness adjustment is a closed-loop control system and is continuously compensated, corrected and adjusted until the levelness is qualified.
After the levelness adjustment is completed, the moving part adjusts the visual part to align with the first part B1, the control part calls the first object parameter, and the position coordinates of each hole site on the first part B1 are detected through the visual part to obtain a first part detection result. In the subsequent process, the first detection result is compared with a preset theoretical coordinate, and the coordinate deviation is calculated. So far, the first part B1 detects that the task is completed.
And S60, judging whether the first part meets the preset specification requirement or not based on the detection result of the first part.
On the self-movement detection device, the control part acquires a first part detection result and judges whether the first part meets a preset specification requirement or not based on the detection result of the first part B1. Here, the control unit includes a comparison unit, a judgment unit, and preset theoretical coordinate parameters. And the comparison unit is used for comparing the first detection result with the theoretical position coordinate and obtaining a deviation value between the first detection result and the theoretical position coordinate. And the judging unit is used for comparing the deviation value with a preset deviation value of theoretical specification requirements, and judging that the deviation meets the specification requirements when the deviation value is within the upper limit and the lower limit of the theoretical deviation value, namely, the first part detection result meets the preset specification requirements. When the deviation is not within the upper limit and the lower limit of the theoretical deviation, the deviation is not satisfied with the specification requirement, and the first part detection result is not satisfied with the preset specification requirement.
When the first part B1 meets the preset specification requirement, sending control information of batch processing to the circuit board processing equipment; and when the first piece does not meet the preset specification requirement, controlling the self-movement detection equipment to generate correction parameters. In this embodiment, control information of batch processing is sent to the upper computer, specifically, C03 sends information that the first part is detected to be qualified from the control part of the movement detection device to the D12 circuit board processing device, and the D12 circuit board processing device sends control information of batch processing to the M01 upper computer. And the M01 upper computer calls the D12 circuit board processing equipment to carry out batch feeding from the mobile transportation equipment, and the D12 circuit board processing equipment starts to carry out batch drilling processing tasks. If the first part detection result does not meet the preset specification requirement, the judging unit judges that the first part detection is not qualified, and when the first part detection result is not qualified, the control part calculates compensation parameters based on the coordinate deviation value compared by the detection result and the comparing unit and generates correction parameters. Meanwhile, the C03 sends the correction parameters to the D12 circuit board processing equipment from the control part of the mobile detection equipment, the D12 circuit board processing equipment receives the correction parameters, the circuit board processing equipment comprises a second object parameter of a built-in processing circuit board, and the circuit board processing equipment integrates the received correction parameters into the second object parameter to form a second characteristic parameter. Under the control of the upper computer M01 dispatching control system, the D12 circuit board processing equipment uses the second characteristic parameters to execute the first processing task again.
In the process of executing the first part processing task again, the method comprises the steps that D12 circuit board processing equipment sends first part processing requirement task information to an M01 upper computer dispatching control system, the M01 upper computer calls self-moving transportation equipment T04 to transfer a first part B2 to the circuit board processing equipment, the method further comprises the step that D12 circuit board processing equipment calls second characteristic parameters, and the first part B2 processing task is executed again. After the first part B2 is processed, the D12 circuit board processing equipment transfers the first part B2 to the self-moving detection equipment C03, and the C03 receives the second processed first part B2 from the self-moving detection equipment to execute a first part detection task. Of course, before the first member detection task is executed, cleaning the first member, adjusting the levelness of the detection device and the like are further included. Before the detection device executes the first piece detection task, the C03 self-movement detection equipment integrates the correction parameters into the first object parameters to form first characteristic parameters, and the C03 self-movement detection equipment calls the first characteristic parameters to execute the B2 first piece detection task again. It should be noted that, after the correction parameters generated by the first-component detection task are integrated into the first object parameters, the first feature parameters are formed, and when the first-component detection task is executed for the second time, the first feature parameters are called, that is, the first object parameters are obtained by integrating the correction parameters. When the detection result of the first part of the second time meets the preset specification requirement, C03 sends control information of qualified first part detection from the mobile detection equipment to the circuit board processing equipment D12, and the circuit board processing equipment D12 sends control information of batch processing to the M01 upper computer; and when the first piece does not meet the preset specification requirement, controlling the self-movement detection equipment to generate correction parameters again. So reciprocating, integrate the correction parameter at every turn into circuit board processing equipment and from the removal check out test set, constantly correct and compensate the deviation of first piece, improve circuit board processing equipment's machining precision to improve circuit board processing equipment and process the quality in batches.
According to the circuit board detection method, by matching the automatic detection equipment with the upper computer dispatching control system, the automatic detection equipment moves to the circuit board processing equipment for detection, so that the time-space conversion time of the first part is reduced, the labor intensity is reduced, and the transportation risk is reduced; timely sampling detection is carried out, and the real-time performance and the detection efficiency of detection information are improved; the production efficiency and the product quality of the circuit board are effectively improved, and the production time cost is reduced.
