Description

Technical Field

[0001] The present invention belongs to the technical field of substrate processing, and in particular relates to a substrate processing technology and production line. Background Art

[0002] In the field of electronic substrate processing, existing processes lack standardized control over the storage environment after substrate drying and the cleaning process before cutting, resulting in the following technical defects:

[0003] In the prior art, the substrate is directly exposed to the workshop environment after drying. The dried substrate is easily reabsorbed by moisture due to fluctuations in environmental humidity and may be contaminated, affecting the adhesion of subsequent solder paste printing and the quality of reflow soldering, reducing soldering reliability, and substrates stored for a long time may also have structural defects. At the same time, the existing process does not set a debris cleaning step after the substrate is divided. The glass fiber and metal debris generated by the cutting remain directly on the surface of the substrate. These debris will adhere to the cutting edge or gap, resulting in rough cutting edges of the substrate and reduced accuracy. Summary of the Invention

[0004] In view of this, the present invention provides a substrate processing technology and production line to solve the problems of moisture absorption after drying and incomplete cleaning of cutting debris during substrate processing in the prior art.

[0005] The technical solution adopted in the present invention is as follows:

[0006] A substrate processing process, comprising:

[0007] S1, drying the substrate, printing solder paste on the dried substrate, mounting electronic components on the substrate printed with the solder paste, and reflow curing the substrate with the mounted electronic components;

[0008] In S1, the drying temperature is 60° C.-70° C., and the drying time is 3 hours-4 hours. The dried substrate is placed in an oven before use. The substrate in the oven is used within 10 days after drying.

[0009] S2. Performing optical inspection on the substrate after reflow curing by optical inspection equipment;

[0010] S3, dividing the substrates that have passed the optical inspection, and performing hand-insertion component welding on the divided substrates;

[0011] In S3, before the substrate is divided, debris on the surface of the substrate is cleaned.

[0012] S4. After the welding is completed, the performance of the substrate is checked. The substrates that pass the performance inspection are potted with potting materials. After potting, the products are inspected and finally the qualified products are put into storage;

[0013] A substrate processing production line includes: a drying oven, a printing machine, a placement machine, a curing oven, an optical inspection machine, a substrate dividing machine, a welding machine, a CDI substrate inspection machine, a potting machine and a CDI finished product inspection machine which are sequentially arranged on the production line.

[0014] A substrate cutting machine includes a workbench with brackets on either side of the top of the workbench, a lifting device mounted on the brackets, a first guide rail mounted on top of the lifting device, the first guide rail extending along the length of the workbench, a first electric slide mounted on the first guide rail for sliding engagement therewith, a second guide rail mounted above the first electric slide rail for sliding engagement therewith, and a cutter mounted on the bottom of the second electric slide rail. The lifting device is a pneumatic cylinder.

[0015] In this technical solution, it should be noted that the workbench in the substrate splitting machine is used to place substrates arranged in an array and provide stable support. The two side brackets on the top are fixed with a lifting device to ensure the stability of its vertical lifting. The lifting device drives the first guide rail to lift and lower along the Z axis to achieve contact or separation between the cutting machine and the substrate. The first guide rail is arranged along the length direction of the workbench (X axis), and the first electric slide rail thereon can move along the X axis to position the cutting machine to the starting position of the row cutting of the substrate (such as the left end or right end of a row). The second guide rail is arranged along the width direction of the workbench (Y axis), and the second electric slide rail thereon can move along the Y axis to perform the row direction cutting action; the specific working principle is: when row cutting is required, first the first electric slide rail is moved along the X axis to move the cutting machine to the starting position of the row cutting of the substrate. The first electric slide moves along the X-axis to position the cutting machine at the starting position of the target row (such as the left end of the first row). Then the lifting device drives the cutting machine down to the cutting height and contacts the substrate. Then the second electric slide moves along the Y-axis, driving the cutting machine to move from the left end of the row to the right end (or vice versa) to complete the entire row cutting. After the row cutting is completed, the lifting device drives the cutting machine to rise and leave the substrate. The first electric slide moves along the X-axis to the starting position of the next row again. The above process is repeated until all rows are cut. If column cutting is required, the second electric slide is positioned to the starting position of the column along the Y-axis, and the first electric slide moves along the X-axis to perform cutting. This structure realizes row and column cross cutting of the substrate array through the flexible combination of X-axis positioning of rows / columns and Y-axis execution of cutting.

[0016] Preferably, a box body is provided on one side of the top of the workbench, and the box body is arranged along the width direction of the workbench. One side of the box body is provided with a plurality of air nozzles connected thereto, and the air outlets of the plurality of air nozzles are facing the workbench. A piston plate is slidably embedded in the box body, and a piston rod is provided at the end of the piston plate away from the air nozzle, and the end of the piston rod away from the piston plate slides out of the box body.

[0017] In this technical solution, it should be noted that the box body arranged on one side of the top of the workbench extends in the width direction, and a variable-volume air cavity is formed in its interior by a slidingly embedded piston plate. The piston rod connected to one end of the piston plate can pass through the box body, and the air outlets of several air nozzles connected to the other side of the box body are facing the workbench; when the piston rod is pushed, the piston plate slides in the width direction in the box body, compressing the air in the air cavity, so that the air is ejected from the air nozzle at high speed to form an airflow, which acts on the substrate on the surface of the workbench, and blows away pollutants such as glass fibers and metal debris generated during the cutting process from the surface of the substrate; this structure drives the airflow through mechanical movement, does not require an additional air source, and can be cleaned immediately after the substrate is split. The array layout of the air nozzles ensures that the airflow covers the entire width direction of the workbench, thereby achieving comprehensive blowing of the substrate surface.

[0018] Preferably, a push plate is provided at one end of the piston rod away from the piston plate, and a spring is sleeved on the piston rod, one end of the spring is connected to the box body, and the other end is connected to the push plate.

[0019] In this technical solution, it should be noted that the push plate provided at one end of the piston rod away from the piston plate increases the operating force area, which is convenient for manually pushing the piston rod. One end of the spring sleeved on the piston rod is connected to the box body and the other end is connected to the push plate to form an elastic reset mechanism; when the push plate is pushed, the piston rod drives the piston plate to slide toward the air nozzle to compress the air in the box body, and the air is ejected from the air nozzle to clean the debris on the surface of the substrate. After releasing the push plate, the spring elastic force drives the piston plate to slide in the opposite direction and reset, so that the air cavity of the box body re-inhales air to store energy for the next cleaning; this structure converts manual thrust into reciprocating motion of the piston plate through the cooperation of the push plate and the spring, thereby realizing the pulse jet cleaning function of the air nozzle, without the need for electric or pneumatic drive devices, with the characteristics of simple structure, labor-saving operation and automatic reset, and can continuously cycle for substrate cleaning.

[0020] Preferably, one end of the first guide rail is fixedly connected to a connecting frame, and a push rod is provided at the bottom of the connecting frame, and the push rod is arranged along the length direction of the workbench; the upper and lower ends of the push plate are respectively provided with a first guide surface and a second guide surface, the first guide surface is inclined downward in the direction away from the box body, and the second guide surface is inclined upward in the direction away from the box body, and the first guide surface and the second guide surface are opposite to the end of the push rod.

[0021] In this technical solution, it should be noted that a push rod is provided at the bottom of the connecting frame fixed at one end of the first guide rail along the length direction of the workbench, and a first guide surface inclined downward in the direction away from the box body and a second guide surface inclined upward are respectively provided at the upper and lower ends of the push plate, and the two guide surfaces are opposite to the end of the push rod; when the cutting machine finishes cutting and moves upward, it drives the push rod to move upward synchronously and squeeze the second guide surface, so that the push plate overcomes the spring force and moves in the direction away from the box, the piston plate slides in the box to compress the air, and the air nozzle sprays the air flow to clean the surface of the substrate after cutting; when the cutting machine descends to prepare for the next cutting, the push rod moves downward to squeeze the first guide surface, and the push plate moves away from the box again The push plate moves horizontally, triggering the air nozzle to spray air twice, thus achieving double cleaning of the cutting area. The structure cleverly utilizes the lifting action of the cutting machine itself, and converts the vertical movement into the horizontal movement of the push plate through the cooperation of the push rod and the guide surface, driving the piston plate to move back and forth to generate pulsed airflow, which can complete the debris cleaning synchronously during the cutting process without the need for an additional power source. The reset action of the spring ensures that the push plate automatically returns to its position, forming a cyclic linkage mechanism of "cutting up-cleaning-cutting down-cleaning again", which effectively improves the cleaning efficiency and the degree of automation, reduces manual intervention and avoids the influence of debris residue on subsequent processes. At the same time, the compact mechanical structure reduces the complexity of the equipment and the maintenance cost.

[0022] Preferably, the end of the push rod is rotatably connected to a roller, and the roller is opposite to both the first guide surface and the second guide surface.

[0023] In this technical solution, it should be noted that the roller rotatably connected to the end of the push rod is opposite to the first guide surface and the second guide surface of the push plate. When the push rod rises and falls with the cutting machine, the roller rolls along the guide surface instead of sliding, converting the traditional sliding friction into rolling friction; this design significantly reduces the friction between the push rod and the guide surface, making the push plate move more smoothly, avoiding the push rod from getting stuck or the guide surface from being worn due to excessive friction resistance. At the same time, the arc contact surface of the roller forms a line contact with the guide surface, which can evenly transmit the thrust and ensure the stability of the horizontal movement of the push plate.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] 1. In the present invention, the dried substrates are stored in an oven and used within 10 days. The constant temperature and humidity environment in the oven forms a closed-loop moisture-proof protection, preventing secondary moisture absorption caused by humidity fluctuations in the workshop environment. Debris on the substrate surface is cleaned before cutting, effectively removing glass fiber and metal debris left during the cutting process, thereby avoiding the problem of low cutting accuracy caused by debris.

[0026] 2. In the present invention, the cutting machine's own lifting action is utilized, and the vertical movement is converted into horizontal movement of the push plate through the cooperation of the push rod and the guide surface, driving the piston plate to reciprocate to generate pulsed airflow. The debris cleaning can be completed synchronously during the cutting process without the need for an additional power source. The reset action of the spring ensures that the push plate automatically returns to its position, forming a "cutting up-cleaning-cutting down-cleaning again" cyclic linkage mechanism, which effectively improves the cleaning efficiency and degree of automation, reduces manual intervention and avoids the impact of debris residue on subsequent processes. At the same time, the compact mechanical structure reduces the complexity of the equipment and maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] like Figure 2-Figure 6 As shown, this embodiment proposes a substrate processing production line, including: a drying furnace, a printing machine, a placement machine, a curing oven, an optical inspection machine, a substrate dividing machine, a welding machine, a CDI substrate 2 inspection machine, a potting machine and a CDI finished product inspection machine which are sequentially arranged on the production line.

[0051] Example 3

[0052] like Figure 2As shown, this embodiment provides a substrate splitting machine, which includes a workbench 1. Brackets 3 are provided on both sides of the top of the workbench 1. A lifting device 4 is provided on the brackets 3. A first guide rail 5 is provided on the top of the lifting device 4. The first guide rail 5 is arranged along the length of the workbench 1. A first electric slide rail 6 is provided on the first guide rail 5 to slide with the first guide rail 6. A second guide rail 7 is provided above the first electric slide rail 6. The second guide rail 7 is arranged along the width of the workbench 1. A second electric slide rail 8 is provided on the second guide rail 7 to slide with the second guide rail 8. A cutting machine 9 is provided at the bottom of the second electric slide rail 8. The lifting device 4 is a cylinder. It should be noted that the workbench 1 in the substrate splitting machine is used to place the substrates 2 arranged in an array and provide stable support. The top two side brackets 3 fix the lifting device 4 to ensure its vertical lifting stability. The lifting device 4 drives the first guide rail 5 to lift and lower along the Z axis to realize the contact or separation of the cutting machine 9 and the substrate 2. The first guide rail 5 is arranged along the length direction (X axis) of the workbench 1, and the first electric slide rail 6 thereon can move along the X axis to position the cutting machine 9 to the starting position of the row cutting of the substrate 2 (such as the left or right end of a row). The second guide rail 7 is arranged along the width direction (Y axis) of the workbench 1, and the second electric slide rail 8 thereon can move along the Y axis to perform the row direction cutting action; the specific working principle is: when row cutting is required, first move the first electric slide rail 6 along the X axis to The cutting machine 9 is moved to the starting position of the target row (such as the left end of the first row), and then the lifting device 4 drives the cutting machine 9 to descend to the cutting height and contact the substrate 2. Then the second electric slide 8 moves along the Y axis, driving the cutting machine 9 to move from the left end of the row to the right end (or reverse) to complete the entire row cutting; after the row cutting is completed, the lifting device 4 drives the cutting machine 9 to rise and separate from the substrate 2, and the first electric slide 6 moves along the X axis to the starting position of the next row again, and the above process is repeated until all rows are cut; if column cutting is required, the second electric slide 8 is positioned to the starting position of the column along the Y axis, and the first electric slide 6 moves along the X axis to perform cutting; this structure realizes row and column cross cutting of the substrate 2 array through the flexible combination of X-axis positioning of rows / columns and Y-axis execution of cutting.

[0053] like Figure 3 and Figure 4As shown, in this embodiment, a box body 10 is provided on one side of the top of the workbench 1, and the box body 10 is arranged along the width direction of the workbench 1. One side of the box body 10 is provided with a plurality of air nozzles 11 connected thereto, and the air outlets of the plurality of air nozzles 11 are facing the workbench 1. A piston plate is slidably embedded in the box body 10, and a piston rod 15 is provided at the end of the piston plate away from the air nozzle 11, and the end of the piston rod 15 away from the piston plate slides out of the box body 10. It should be noted that the box body 10 arranged on one side of the top of the workbench 1 extends along the width direction, and a variable-volume air cavity is formed inside the box body by a slidingly embedded piston plate. The piston rod 15 connected to one end of the piston plate can pass through the box body 10, and the air outlets of several air nozzles 11 connected to the other side of the box body 10 are facing the workbench 1; when the piston rod 15 is pushed, the piston plate slides in the width direction in the box body 10, compressing the air in the air cavity, so that the air is ejected from the air nozzle 11 at high speed to form an airflow, which acts on the substrate 2 on the surface of the workbench 1, and blows away pollutants such as glass fibers and metal debris generated during the cutting process from the surface of the substrate 2; this structure drives the airflow through mechanical movement, does not require an additional air source, and can be cleaned immediately after the substrate 2 is split. The array layout of the air nozzles 11 ensures that the airflow covers the entire width direction of the workbench 1, thereby achieving a comprehensive purge of the surface of the substrate 2.

[0054] like Figure 4 and Figure 5 and Figure 6 As shown, in this embodiment, a push plate 17 is provided at one end of the piston rod 15 away from the piston plate, and a spring 16 is sleeved on the piston rod 15. One end of the spring 16 is connected to the box body 10, and the other end is connected to the push plate 17. The spring 16 is mounted on the piston rod 15 and is connected to the box body 10 at one end and the push plate 17 at the other end to form an elastic reset mechanism; when the push plate 17 is pushed, the piston rod 15 drives the piston plate to slide toward the air nozzle 11 to compress the air in the box body 10, and the air is ejected from the air nozzle 11 to clean the debris on the surface of the substrate 2. After the push plate 17 is released, the elastic force of the spring 16 drives the piston plate to slide in the opposite direction and reset, so that the air cavity of the box body 10 re-inhales air to store energy for the next cleaning; this structure converts the manual thrust into the reciprocating motion of the piston plate through the cooperation of the push plate 17 and the spring 16, thereby realizing the pulse jet cleaning function of the air nozzle 11, without the need for an electric or pneumatic drive device, and has the characteristics of simple structure, labor-saving operation and automatic reset, and can continuously cycle to clean the substrate 2.

[0055] like Figure 4 and Figure 5 and Figure 6As shown, in this embodiment, one end of the first guide rail 5 is fixedly connected to a connecting frame 12, and a push rod 13 is provided at the bottom of the connecting frame 12, and the push rod 13 is arranged along the length direction of the workbench 1; the upper and lower ends of the push plate 17 are respectively provided with a first guide surface 18 and a second guide surface 19, the first guide surface 18 is inclined downward in the direction away from the box body 10, and the second guide surface 19 is inclined upward in the direction away from the box body 10, and the first guide surface 18 and the second guide surface 19 are opposite to the end of the push rod 13. It should be noted that, the bottom of the connecting frame 12 fixed at one end of the first guide rail 5 is provided with a push rod 13 along the length direction of the workbench 1, and the upper and lower ends of the push plate 17 are respectively provided with a first guide surface 18 inclined downward in the direction away from the box body 10 and a second guide surface 19 inclined upward, and the two guide surfaces are opposite to the end of the push rod 13; when the cutting machine 9 moves upward after cutting, it drives the push rod 13 to move upward synchronously and squeeze the second guide surface 19, so that the push plate 17 overcomes the elastic force of the spring 16 and moves away from the box body 10, the piston plate slides in the box body 10 to compress the air, and the air nozzle 11 sprays the air flow to clean the surface of the cut substrate 2; when the cutting machine 9 descends to prepare for the next cutting, the push rod 13 moves downward to squeeze the first guide surface 18, and the push plate 17 moves away from the box body 10 again, triggering the air nozzle 11 to spray air for the second time, thereby achieving double cleaning of the cutting area; this structure cleverly utilizes the lifting action of the cutting machine 9 itself, and converts the vertical movement into the horizontal movement of the push plate 17 through the cooperation of the push rod 13 and the guide surface, driving the piston plate to move back and forth to generate a pulsed airflow, which can complete the debris cleaning synchronously during the cutting process without the need for an additional power source. The reset effect of the spring 16 ensures that the push plate 17 automatically returns to its position, forming a "cutting up-cleaning-cutting down-cleaning again" cyclic linkage mechanism, which effectively improves the cleaning efficiency and the degree of automation, reduces manual intervention and avoids the influence of debris residue on subsequent processes. At the same time, the compact mechanical structure reduces the complexity of the equipment and the maintenance cost.

[0056] like Figure 6 As shown, in this embodiment, the end of the push rod 13 is rotatably connected to a roller 14, and the roller 14 is opposite to both the first guide surface 18 and the second guide surface 19. It should be noted that the roller 14 rotatably connected to the end of the push rod 13 is opposite to the first guide surface 18 and the second guide surface 19 of the push plate 17. When the push rod 13 is raised and lowered along the cutting machine 9, the roller 14 rolls along the guide surface instead of sliding, converting traditional sliding friction into rolling friction. This design significantly reduces the friction between the push rod 13 and the guide surface, making the push plate 17 move more smoothly and avoiding the push rod 13 from getting stuck or the guide surface from being worn due to excessive friction resistance. At the same time, the arc contact surface of the roller 14 forms a line contact with the guide surface, which can evenly transmit the thrust and ensure the stability of the horizontal movement of the push plate 17.

[0057] The working principle of this embodiment is:

[0058] The substrate 2 processing production line is connected in series in the form of an assembly line, with a drying furnace, a printing machine, a placement machine, a curing oven, an optical inspection machine, a substrate splitting machine, a welding machine, a CDI substrate 2 inspection machine, a potting machine and a CDI finished product inspection machine. The substrate 2 first enters the drying furnace for drying and then is transferred to an oven for storage. The dried substrate 2 is coated with solder paste by the printing machine, mounted with electronic components by the placement machine, and reflowed and cured in the curing oven to form a preliminary component; the cured substrate 2 is fully inspected by the optical inspection machine and then enters the substrate splitting machine. The splitting machine separates the entire board into independent units according to the array layout of the substrate 2 through 9 rows and columns of the cutting machine. The debris is automatically blown away by the cleaning device before and after cutting; the split substrate 2 is completed with hand-inserted components by the welding machine, and the performance is tested by the CDI substrate 2 inspection machine. Qualified products are encapsulated and protected by the potting machine, and finally inspected by the CDI finished product inspection machine and put into storage.

[0059] The cylinders fixed on the two side brackets 3 in the substrate splitting machine serve as the lifting device 4 to drive the first guide rail 5 to rise and fall in the vertical direction to realize the contact or separation of the cutting machine 9 and the substrate 2. The first guide rail 5 is set along the length direction of the workbench 1, and the first electric slide rail 6 moves along it to position the cutting machine 9 to the starting position of the target column. The second guide rail 7 is set along the width direction, and the second electric slide rail 8 moves along it to position the cutting machine 9 to the starting position of the target row. The first and second electric slide rails 8 move in the length and width directions respectively to realize the cross-cutting of rows and columns of the array substrate 2. A variable air cavity is formed inside the box 10 on one side of the workbench 1 through a piston plate. The upper and lower guide surfaces of the push plate 17 at the end of the piston rod 15 connected to the piston plate are opposite to the push rod 13 at the bottom of the connecting frame 12, and the roller 14 at the end of the push rod 13 rolls along the guide surface. When the cutting machine 9 is raised or lowered, the push rod 13 squeezes the guide surface through the roller 14 to drive the push plate 17 to move, so that the piston plate compresses the air cavity and sprays air from the air nozzle 11 to clean the surface of the substrate 2. The elastic force of the spring 16 drives the push plate 17 to reset so that the air cavity inhales air for the next cleaning. The array layout of the air nozzles 11 covers the width of the workbench 1, and the roller 14 converts sliding friction into rolling friction to ensure smooth movement of the push plate 17.
