Description

Technical Field

[0001] The present invention relates to the technical field of circuit board quality inspection, and in particular to a circuit board quality inspection communication system and a communication method. Background Art

[0002] Flexible printed circuit boards are referred to as soft boards. They are made into conductor circuit patterns on the surface of a flexible substrate using photo-imaging pattern transfer and etching processes. The surface and inner layer of double-sided and multi-layer circuit boards are electrically connected through metallized holes, and the surface of the circuit pattern is insulated. After the flexible circuit board is produced, it needs to be tested to see if it is qualified, and the bad position and bad condition of the circuit board need to be analyzed. The inspection of flexible circuit boards includes multiple links such as microscopic inspection / special inspection, process quality inspection (MQC), finished product quality inspection (FQC), factory sampling inspection (OQC), packaging and shipment, etc., but not all flexible circuit boards need to undergo every test, but are inspected according to specific order requirements.

[0003] Traditional flexible circuit board inspection usually sets up multiple inspection areas corresponding to different inspection processes. For example, a number of fixed microscopic inspection stations are set up in the microscopic inspection area, a number of quality inspection stations are set up in the process quality inspection area, and a number of factory inspection stations are set up in the finished product factory sampling inspection area. Each employee performs his or her duties in his or her respective job position. After microscopic inspection, the flexible circuit board is classified according to good and bad quality. For example, if all circuit board units in the same flexible circuit board are all qualified or have one defective, two defective, three defective, four defective, five or more defective, they are packed in different boxes. According to the specific requirements of the order, defective products with different numbers of pieces are distributed to different processing personnel, and qualified products and defective pieces that meet the requirements are distributed to the process quality inspection area. The staff of the process quality inspection area inspects the products again and classifies them according to qualified and unqualified products. Unqualified products are returned to the microscopic inspection area or the defective product recycling area, and qualified products are sent to the finished product quality inspection area for full inspection. Unqualified products are returned, and qualified products are transferred to the finished product factory sampling inspection area for sampling inspection. After passing the inspection, they are packaged and shipped. During the entire inspection process, products are transferred manually, which not only consumes workers' time and energy and reduces inspection efficiency, but also easily causes new defects in circuit boards due to collisions or shaking during the transportation process. The low degree of automation requires further improvement. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a circuit board quality inspection communication system and communication method which can improve work efficiency, reduce labor intensity and improve the degree of automation.

[0005] In order to achieve the above object, the solution of the present invention is:

[0006] A circuit board quality inspection communication system includes a conveyor belt, a central control computer arranged on one side of the conveyor belt thread head, and multiple light tables arranged on both sides of the conveyor belt, each light table is provided with an independent workstation number, and the light tables include at least one mirror inspection station, at least one process quality inspection station, at least one random inspection station, at least one point-to-point periodic station, and at least one scanning and inputting packaging station arranged in sequence along the conveying direction of the conveyor belt, wherein each mirror inspection station and each process quality inspection station is provided with an alarm, an intelligent pager, and a voice receiver, the central control computer is provided with a voice announcer and a display screen, and the alarm, voice receiver, and intelligent pager of each light table are connected to the central control computer.

[0007] Furthermore, a touch LCD terminal controller is installed on each sampling inspection station, and the touch LCD controller is connected to the voice receiver of each process inspection station through a high-definition interface and a high-definition line.

[0008] Furthermore, the intelligent pager includes a normal production button, a soon-to-be-made button, and a waiting-for-made button.

[0009] Furthermore, the circuit board quality inspection communication system also includes a sampling control computer. Each sampling station is provided with a touch screen connected to the sampling control computer. The sampling control computer is connected to the voice receiver of each process quality inspection station. The station number of each mirror inspection station and each process quality inspection station is displayed on each touch screen. After the station number is selected, the corresponding station receives a voice reminder.

[0010] Furthermore, a quality abnormality indicator light is provided on the intelligent pager of the process quality inspection station, and the quality abnormality indicator light is connected to the touch-screen LCD terminal controller.

[0011] The present invention also discloses a circuit board quality inspection communication method, which comprises the following steps:

[0012] Step 1: Each microscopic inspection station and each process quality inspection station controls the intelligent caller to be in production, about to be material-waiting, or waiting for material according to the status of the current station number, so that the current status of each station number is displayed on the display screen of the central control computer; if microscopic inspection / special inspection is required, proceed to step 2, and if microscopic inspection / special inspection is not required, proceed to step 3;

[0013] Step 2: The batcher places the batching turnover basket horizontally on the conveyor belt, and the central control computer sends a voice reminder to the inspector at the microscopic inspection station to take the materials from the distribution conveyor belt. If the inspector at the microscopic inspection station is about to wait for materials or waiting for materials, he can also actively call the batcher through the intelligent caller; after the microscopic inspection / special inspection completes the product inspection, it is placed on the return conveyor belt in a vertical manner to the end of the line flowing to the return conveyor belt. The batcher receives the product. If the horizontally placed product is received, it is determined whether the returned product after inspection by the finished product factory inspector in the finished product sampling area has not been accepted by the corresponding station or the finished product factory inspector has returned the uninspected product. If it is a returned product, it is directly distributed to the corresponding station personnel. If it is an uninspected product, jump to step 3;

[0014] Step 3: The batcher places the product horizontally on the distribution conveyor according to the lighting status of the process quality inspection station on the central control computer display screen, and reminds the corresponding quality inspector to collect the material by voice. The quality inspector can also actively press the smart caller to call the batcher when he is about to wait for the material or waiting for the material. The quality inspector only takes the horizontal turnover box to take the material;

[0015] Step 4: After the quality inspector at the process quality inspection station completes the work, he / she signs with the station number and places it vertically on the conveyor belt to the finished product sampling area in the turnover box;

[0016] Step 5: Inspection by sampling inspectors: Take the vertically placed turnover frame for sampling inspection. If the sampling inspection is qualified, the product will be placed on the conveyor belt to the counting and periodic workstation; if the sampling inspection is unqualified, the sampling inspector will remind the corresponding inspection workstation, and place the returned products horizontally on the return conveyor belt, and the products will flow to the corresponding workstation, and voice remind the corresponding workstation to pick up the materials; if the product flowing down is a horizontally placed turnover frame, it can be placed horizontally on the return conveyor belt to continue to return, and it can be picked up by the quality inspector in the middle or the thread ends flowing to the return conveyor belt will be fed uniformly by the batcher;

[0017] Step 6: Count and divide the cycle: If OK, place the product on the conveyor belt and flow it to the scanning and packaging station; if NG, transfer it to the relevant processor for processing.

[0018] After adopting the above scheme, the circuit board inspection system of the present invention sets up an assembly line and a central control computer in the circuit board quality inspection workshop, sets up light tables on both sides of the assembly line distributed in sequence according to the inspection order, and connects the light tables to the central control computer, so that each station can communicate with the central control computer, and the batcher can timely supply materials to each station according to the current status of the station number on the central control computer display screen, and the inspection station can also actively call for batching, and the intelligent pager and voice receiver realize the interaction between the batcher and the inspection station, which greatly improves the inspection efficiency of the circuit board. The setting of the conveyor belt effectively connects various inspection links together, improves the inspection efficiency of different inspection processes, reduces the labor intensity of employees, and avoids secondary damage to the product.

[0031] The mirror inspection station 31 and the process quality inspection station 32 need the batcher to batch the materials. When the mirror inspection station 31 and the process quality inspection station 32 are working normally, press the normal production button, the green indicator light of the intelligent caller is on, and the display screen of the central control computer 2 shows that the station is in normal production and is indicated in green; when the materials are about to be prepared, press the waiting button, the yellow indicator light of the intelligent caller is on, and the display screen of the central control computer 2 shows that the station is about to be prepared and is indicated in yellow; when the materials are waiting, press the waiting button, the red indicator light of the intelligent caller is on, and the display screen of the central control computer 2 shows that the station is waiting for materials and is indicated in red. After the batcher has prepared the materials, he calls the waiting station to take the materials. After the materials are prepared, it switches to the normal production state.

[0032] The sampling station 33 is set after the process quality inspection station 32, and is used to sample the products that have been inspected. After the product is qualified in the sampling inspection, it will be transmitted to the next process. If the product is unqualified in the sampling inspection, it needs to be returned to the corresponding process quality inspection station 32. Therefore, the sampling station 33 needs to interact with the quality inspection station 32. A touch LCD terminal controller can be installed on each sampling station 33. The touch LCD controller is connected to the voice receiver of each process quality inspection station through a high-definition interface and a high-definition line; a quality abnormality indicator light can also be set on the smart pager of the process quality inspection station 32. When the sampled product is NG, the sampling personnel operate the touch LCD controller, select the corresponding station to return the NG product, and the corresponding station receives a voice reminder. At the same time, the quality abnormality indicator light on the smart pager lights up red.

[0033] In addition to using a touch LCD controller to interact with the process quality inspection station 32, a random inspection control computer can also be installed. Each random inspection station is provided with a touch screen connected to the random inspection control computer. The random inspection control computer is connected to the voice receiver and intelligent pager of each process quality inspection station. The station number of each mirror inspection station and each process quality inspection station is displayed on each touch screen. After the station number is selected, the corresponding station receives a voice reminder, and the quality abnormality indicator light of the intelligent pager lights up red.

[0034] The present invention also discloses a circuit board quality inspection communication method, which comprises the following steps:

[0035] Step 1: Each microscopic inspection station 31 and each process quality inspection station 32 controls the intelligent pager according to the status of the current station number to be any one of waiting for material collection, quality abnormality, lack of materials or urgent lack of materials, so that the current status of each station number is displayed on the display screen of the central control computer; if microscopic inspection / special inspection is required, go to step 2, and if microscopic inspection / special inspection is not required, go to step 3;

[0036] Step 2: The batcher places the batching turnover basket horizontally on the conveyor belt, and the central control computer sends a voice reminder to the inspector at the microscopic inspection station to take the materials from the distribution conveyor belt. If the inspector at the microscopic inspection station is about to wait for materials or waiting for materials, he can also actively call the batcher through the intelligent caller; after the microscopic inspection / special inspection completes the product inspection, it is placed on the return conveyor belt in a vertical manner to the end of the line flowing to the return conveyor belt. The batcher receives the product. If the horizontally placed product is received, it is determined whether the returned product after inspection by the finished product factory inspector in the finished product sampling area has not been accepted by the corresponding station or the finished product factory inspector has returned the uninspected product. If it is a returned product, it is directly distributed to the corresponding station personnel. If it is an uninspected product, jump to step 3;

[0037] Step 3: The batcher places the product horizontally on the distribution conveyor according to the lighting status of the process quality inspection station on the central control computer display screen, and reminds the corresponding quality inspector to collect the material by voice. The quality inspector can also actively press the smart caller to call the batcher when he is about to wait for the material or waiting for the material. The quality inspector only takes the horizontal turnover box to take the material;

[0038] Step 4: After the quality inspector at the process quality inspection station completes the work, he / she signs with the station number and places it vertically on the conveyor belt to the finished product sampling area in the turnover box;

[0039] Step 5: Inspection by sampling inspectors: Take the vertically placed turnover frame for sampling inspection. If the sampling inspection is qualified, the product will be placed on the conveyor belt to the counting and periodic workstation; if the sampling inspection is unqualified, the sampling inspector will remind the corresponding inspection workstation, and place the returned products horizontally on the return conveyor belt, and the products will flow to the corresponding workstation, and voice remind the corresponding workstation to pick up the materials; if the product flowing down is a horizontally placed turnover frame, it can be placed horizontally on the return conveyor belt to continue to return, and it can be picked up by the quality inspector in the middle or the thread ends flowing to the return conveyor belt will be fed uniformly by the batcher;

[0040] Step 6: Counting and dividing into cycles: Counting and dividing into cycles is used to classify qualified products. The products are printed with the customer's cycle code, some are by day, some are by week, and they are confirmed by scanning into the computer, and the number of products is counted. After the statistics are completed, the next process is transferred to the next process for product packaging. If it is ok, the product is placed on the conveyor belt and flows to the scanning and input packaging station; if it is NG, it is transferred to the relevant processor for processing.

[0041] The present invention installs an intelligent pager 5 and a voice receiver 6 at the process inspection station 32 and the mirror inspection station 31. According to the current state of the station, the intelligent pager 5 is set to normal production (green light), about to wait for material (yellow light) or waiting for material (red light), and the three states of normal production, about to wait for material, and waiting for material are fed back to the central control computer 2 through buttons. The display screen of the central control computer 2 dynamically displays the station status of each station. After the ingredients are prepared for the station about to wait for material or waiting for material, the state is automatically switched to normal production, and the corresponding station is locked as normal production by default within 20 minutes. The touch LCD terminal controller or touch screen of the sampling inspection station 33 can select the corresponding station to return the sampling NG products.

[0042] The central control computer 2 is equipped with a voice broadcast device, which scrolls the voice broadcast reminder in the order of switching to the waiting and waiting stations at each station. For example, call "waiting for materials at station 8". After the materials are prepared for the waiting and waiting stations, the corresponding station will announce the materials by voice, such as "Please receive the materials at station 8". The corresponding personnel have noticed the status reminder and have started to deal with it. The voice broadcast can be manually canceled. The sampling station 33 samples the unqualified NG products. After selecting the station number of the NG product, the corresponding station receives a voice reminder, such as "Please check the sampling return at station 8".

[0043] The above embodiments and illustrations do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
