Description

Technical Field

[0001] The present invention relates to the technical field of circuit board production, and in particular to a PCB circuit board production device. Background Art

[0002] PCB circuit board is a plate-like structure used for electrical connection and mechanical support of electronic components. It is usually divided into single-sided board, multi-sided board and multi-layer board. Its production usually requires design (using design software to create circuit diagrams and layouts), etching (removing unnecessary copper foil through chemical methods to leave circuit patterns), drilling (drilling mounting holes for component pins and through holes for interlayer connections), electroplating (plating copper in through holes to achieve electrical connection), lamination (pressing multilayer boards together) and final testing.

[0003] For example, a PCB circuit board production equipment with the publication number "CN111712050B" belongs to the field of circuit board manufacturing technology. Its technical scheme is: including an ink pad, the ink pad includes symmetrically arranged columns 1 and 2 and columns 3 and 4, the outer sides of columns 1 and 2 are hinged with a vertical plate, the inner side of the lower end of the vertical plate is fixedly provided with a rectangular frame, the outer side of the other end of the rectangular frame is fixedly provided with an external plate, and a fixed plate is provided between column 3 and the upper part of the column 4; a placement plate is provided on the ink pad and directly below the rectangular frame; an upper swing rod is rotatably provided on optical axis 1, and a lower swing rod is rotatably provided on optical axis 2, and the other ends of the upper swing rod and the lower swing rod are connected by connecting rod 1, and an upper rocker is hingedly provided on the other side of the upper swing rod opposite to connecting rod 1, and a lower rocker is hingedly provided on the other side of the lower swing rod opposite to connecting rod 1; and also includes a limit plate provided below the placement plate. The beneficial effects of the present invention are: assisting manual positioning and fixing of the position of the circuit board.

[0004] However, in the prior art, when printing solder paste on a circuit board, a corresponding stencil is placed on the circuit board, an appropriate amount of solder paste is placed on the stencil, and then an inclined scraper is used to scrape the solder paste into the corresponding holes on the stencil until the holes are filled with the solder paste and firmly adhere to the circuit board below, and then the stencil is removed. In this process, the scraper should not move the solder paste too slowly to avoid too long contact time and too large contact area between the solder paste and the air. If reciprocating scraping of the solder is required, the scraper needs to be moved to the other side of the solder paste and then scraped, which is inconvenient to use. Summary of the invention

[0005] The purpose of the invention is to solve the problem in the prior art that a scraper is not convenient for reciprocating movement when scraping solder paste.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a PCB circuit board production equipment, including a workbench, a slide rail is symmetrically arranged above the workbench, a scraper assembly is slidably arranged between two of the slide rails, end frames are symmetrically slidably arranged at both ends of the workbench, a support plate, a circuit board and a mesh plate are arranged above the workbench between the two end frames and the slide rails from bottom to top, a loading rack is arranged on the workbench, and the support plate, the circuit board and the two ends of the mesh plate are clamped and positioned by two end frames, the scraper assembly includes a bottom plate, a slider and a scraper, the slider is a hollow frame structure, and the slider slides with the slide rail The bottom plate is slidably arranged under the support plate and its two ends are assembled and connected with the bottom of the slider, the scraper is slidably arranged above the mesh plate and its two ends are assembled and connected with the top of the slider, the distance between the scraper and the bottom plate is adjustable, the scraper is a C-shaped structure with an opening downward, two scrapers are provided and symmetrically arranged, the two scrapers are rotatably connected above a connecting plate, a driving mechanism is provided above the connecting plate, the scraper is driven to rotate by the driving mechanism, end plates are provided below the two ends of the connecting plate, a scraper is slidably provided below the connecting plate between the two end plates, and the scraper height is adjustable.

[0007] As a preferred embodiment, the two ends of the scraper and the two ends of the base plate are respectively slidably connected to the inside of the slider through the first tooth plate and the second tooth plate, and a first gear is rotatably provided at the center position of the slider, and the first tooth plate and the second tooth plate are respectively meshed with the two sides of the first gear, and the first gear is driven to rotate by a first motor, and the slider is slidably connected to the slide rail through a second cylinder. By driving the first motor to rotate, the first gear is driven to rotate, and then the first tooth plate and the second tooth plate are driven to slide in opposite directions, so as to achieve an effect of adjusting the distance between the base plate and the scraper, and the second cylinder is set to facilitate the movement of the slider on the slide rail.

[0008] As a preferred embodiment, a positioning shaft is provided above the workbench, and two positioning shafts are provided and located at the same end of the workbench. The positioning shaft passes through the support plate, the circuit board and the mesh plate from bottom to top in sequence. The positioning shaft is provided to facilitate quick installation and positioning of the support plate, the circuit board and the mesh plate. The positioning shaft is located at the end surface of the support plate, so that the scraper assembly will not be hindered by the positioning shaft when loading and unloading.

[0009] As a preferred embodiment, the length and width of the circuit board are longer than the length and width of the stencil, and the inner wall of the end frame is slidably engaged with the circuit board, the stencil and the support plate. By setting the length and width of the circuit board to be longer than the stencil, after the printing of the solder paste is completed, the two end frames are separated to both sides, so that the end frames are detached from the upper stencil, but are still slidably connected to the circuit board. At this time, the two end frames limit the circuit board, and the upper stencil can be lifted vertically and separated from the circuit board through the lifting mechanism, which can avoid the solder paste covering the circuit board from being rubbed crooked when the circuit board is separated from the stencil.

[0010] As a preferred embodiment, slides are symmetrically provided at both ends above the workbench, and one end above the slide is driven to slide with the end frame through the first cylinder. Through the set slide, it is convenient to lift the pallet, circuit board and mesh plate as a whole, and it is convenient to reserve enough space under the pallet to facilitate the sliding of the bottom plate. By driving the first cylinder, the end frame is driven to make corresponding synchronous movements on the slide.

[0011] As a preferred embodiment, the workbench is assembled and connected to the loading rack via a telescopic rod. There are multiple telescopic rods and they are respectively located at the four corners of the loading rack. The workbench and the loading rack are driven by a third cylinder. A first magnetic ring is provided at the lower edge of the loading rack, and a second magnetic ring that is mutually attracted to the first magnetic ring is provided at the upper edge of the stencil. The first magnetic ring is electrically connected to an external power supply. When unloading the stencil, the loading rack is driven downward by contracting the third cylinder until the first magnetic ring and the second magnetic ring are fitted together, and then the first magnetic ring is energized to attract the first magnetic ring and the second magnetic ring. The third cylinder is extended to drive the stencil to move upward in parallel, so as to avoid the printed solder paste from being offset or skewed.

[0012] As a preferred embodiment, the driving mechanism includes a second gear, a rotating shaft and a driving plate. The scraper is rotatably connected to the connecting plate through the rotating shaft at the top, and one end of the rotating shaft is linked to the second gear. The driving plate is provided with two and meshing with the second gear at the bottom. The two second gears are meshed and linked by a main gear. The main gear is driven to rotate by the second motor, and the main gear is driven to rotate by the second motor, thereby driving the two driving plates to move in opposite directions synchronously, and then driving the two second gears to rotate in opposite directions synchronously, thereby realizing the adjustment of the scraper angle, and facilitating the adjustment of the scraper angle according to actual needs.

[0013] As a preferred embodiment, the tops of the two end plates are respectively rotatably connected and fixedly connected to the end faces of the connecting plates, and a gap is left between the bottom of the end plates and the top of the mesh plate. By setting one end plate as a rotatable connection, it is convenient to use a scraper to push excess solder paste from one end of the rotatably connected end plate into the scraper assembly.

[0014] As a preferred embodiment, a screw rod is rotatably provided under the connecting plate, and the screw rod is driven to rotate by a third motor. A threaded sleeve is provided above the scraper through a fourth cylinder, and the threaded sleeve is sleeved on the screw rod. By driving the third motor, the screw rod is driven to rotate, and then the scraper is driven to reciprocate under the connecting plate. By driving the fourth cylinder to extend, the bottom of the scraper is fitted with the top of the screen, which is convenient for pushing out excess solder paste. The fourth cylinder contracts and the scraper moves up a certain distance, which is convenient for flattening the solder paste accumulated in one place during loading.

[0015] As a preferred embodiment, feed ports are connected to the end plate and the scraper plate fixedly connected to the connecting plate, and the two feed ports are arranged at the same height. A cover plate is provided on the side of the scraper away from the fixedly connected end plate. The feed port is used to facilitate the introduction of a certain amount of solder paste onto the screen. The solder paste penetrates the end plate and the scraper and extends to the other side of the scraper. When the scraper is scraping, the cover plate is used to prevent the solder paste from overflowing from the feed port on the scraper to the other side, thereby achieving a better leveling effect.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are:

[0017] The scraper assembly is arranged as an inverted C-shaped structure with end plates at both ends, which can greatly reduce the range of direct contact between solder paste and air, ensure the quality of the adhesive inside the solder paste, and the scraper is provided with two reciprocating scraping movements, making it more convenient to use.

[0018] The present invention drives the two scrapers to rotate synchronously in opposite directions by driving the driving mechanism, so that the angle of the scraper can be adjusted according to the demand, and the distance between the scraper and the bottom plate can be adjusted to achieve the adjustment of the angle and pressure of the scraper during printing, so as to achieve a better printing effect.

[0019] The present invention drives the third motor to rotate the lead screw, thereby driving the scraper to reciprocate under the connecting plate, and drives the fourth cylinder to extend so that the bottom of the scraper fits with the top of the mesh plate to push out excess solder paste. The fourth cylinder contracts and the scraper moves up a certain distance to flatten the solder paste accumulated in one place during loading.

[0020] The present invention contracts the third cylinder to drive the loading rack to move downward until the first magnetic ring is in contact with the second magnetic ring, and then energizes the first magnetic ring to attract the first magnetic ring and the second magnetic ring to each other. The third cylinder extends to drive the stencil to move upward in parallel, thereby preventing the printed solder paste from being offset or skewed. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] like Figure 1 - Fig.12 As shown, a positioning shaft 11 is provided above the workbench 1. Two positioning shafts 11 are provided and are located at the same end of the workbench 1. The positioning shafts 11 pass through the support plate 511, the circuit board 512 and the mesh plate 513 from bottom to top. The positioning shafts 11 are provided to facilitate quick installation and positioning of the support plate 511, the circuit board 512 and the mesh plate 513. The positioning shafts 11 are located at the end surface of the support plate 511, so that the scraper assembly 3 will not be hindered by the positioning shafts 11 when loading and unloading.

[0039] like Figure 1 - Fig.12 As shown, the length and width of the circuit board 512 are longer than the length and width of the stencil 513, and the inner wall of the end frame 4 is slidably engaged with the circuit board 512, the stencil 513 and the support plate 511. By setting the length and width of the circuit board 512 to be longer than the stencil 513, when the solder paste printing is completed, the two end frames 4 are separated to both sides, so that the end frames 4 are separated from the upper stencil 513, but are still slidably connected to the circuit board 512. At this time, the two end frames 4 limit the circuit board 512, and the upper stencil 513 can be lifted vertically and separated from the circuit board 512 through the lifting mechanism, so as to avoid the solder paste covering the circuit board 512 from being rubbed crooked when the circuit board 512 is separated from the stencil 513.

[0040] like Figure 1 - Fig.12 As shown, slides 121 are symmetrically provided at both ends above the workbench 1, and one end above the slide 121 is driven to slide with the end frame 4 through the first cylinder 122. Through the set slide 121, it is convenient to lift the support plate 511, the circuit board 512 and the mesh plate 513 as a whole, and it is convenient to reserve enough space under the support plate 511 to facilitate the sliding of the bottom plate 711. By driving the first cylinder 122, the end frame 4 is driven to perform corresponding synchronous movement on the slide 121.

[0041] like Figure 1 - Fig.12 As shown, the workbench 1 is assembled and connected to the loading rack 6 through a telescopic rod 131 above. There are multiple telescopic rods 131 and they are respectively located at the four corners of the loading rack 6. The workbench 1 and the loading rack 6 are driven by a third cylinder 132. A first magnetic ring 133 is provided at the lower edge of the loading rack 6, and a second magnetic ring 134 is provided at the upper edge of the mesh plate 513 to be attracted to the first magnetic ring 133. The first magnetic ring 133 is electrically connected to an external power supply. When the mesh plate 513 is unloaded, the third cylinder 132 is contracted to drive the loading rack 6 to move downward until the first magnetic ring 133 and the second magnetic ring 134 are fitted together, and then the first magnetic ring 133 is energized to attract the first magnetic ring 133 and the second magnetic ring 134. The third cylinder 132 is extended to drive the mesh plate 513 to move upward in parallel, so as to avoid the printed solder paste from being offset or skewed.

[0042] like Figure 1 - Fig.12 As shown, the driving mechanism includes a second gear 141, a rotating shaft 142 and a driving plate 143. The scraper 713 is rotatably connected to the connecting plate 714 through the rotating shaft 142 at the top. One end of the rotating shaft 142 is linked to the second gear 141. The driving plate 143 is provided with two and meshed with the second gear 141 at the bottom. The two second gears 141 are meshed and linked through a main gear 144. The main gear 144 is driven to rotate by a second motor 145.

[0043] like Figure 1 - Fig.12 As shown, the tops of the two end plates 8 are rotatably connected and fixedly connected to the end faces of the connecting plate 714, respectively, and a gap is left between the bottom of the end plate 8 and the top of the mesh plate 513. By setting one end plate 8 as a rotatable connection, it is convenient to use the scraper 9 to push excess solder paste from one end of the rotatably connected end plate 8 into the scraper assembly 3.

[0044] like Figure 1 - Fig.12 As shown, a screw rod 151 is rotatably provided below the connecting plate 714, and the screw rod 151 is driven to rotate by a third motor 152. A threaded sleeve 154 is provided above the scraper 9 through a fourth cylinder 153, and the threaded sleeve 154 is sleeved on the screw rod 151. By driving the third motor 152, the screw rod 151 is driven to rotate, and then the scraper 9 is driven to reciprocate below the connecting plate 714. By driving the fourth cylinder 153 to extend, the bottom of the scraper 9 is fitted with the top of the screen 513, which is convenient for pushing out excess solder paste. The fourth cylinder 153 contracts, and the scraper 9 moves up a certain distance, which is convenient for flattening the solder paste accumulated in one place during feeding.

[0045] like Figure 1 - Fig.12 As shown, a feed port 161 is connected to the end plate 8 fixedly connected to the connecting plate 714 and the scraper 9. The two feed ports 161 are arranged at the same height. A cover plate 162 is arranged on the side of the scraper 9 that is away from the fixedly connected end plate 8. The feed port 161 is arranged to facilitate the introduction of a certain amount of solder paste onto the mesh plate 513. The solder paste penetrates the end plate 8 and the scraper 9 and extends to the other side of the scraper 9. When the scraper 9 is scraping, the cover plate 162 is arranged to prevent the solder paste from overflowing from the feed port 161 on the scraper 9 to the other side, thereby achieving a better flattening effect.

[0046] Working principle: When performing solder paste feeding operation, the support plate 511, the circuit board 512 and the mesh plate 513 are placed on the workbench 1 from top to bottom in sequence, and then the slider 712 is moved on the slide rail 2, so that the scraper assembly 3 is located at one end of the mesh plate 513, and the two end frames 4 are driven to move toward each other by driving the first cylinder 122 until the support plate 511, the circuit board 512 and the two ends of the mesh plate 513 are limited and clamped. After the positioning is completed, the distance between the scraper 713 and the bottom plate 711 is adjusted so that the bottom of the scraper 713 is close to the top of the mesh plate 513, and the top of the bottom plate 711 is close to the bottom of the support plate 511. When the scraper assembly 3 is located at one end of the mesh plate 513, the solder paste is fed and the solder paste is evenly squeezed into the connecting plate On the mesh plate 513 directly below 714, the scraper 9 is moved up to leave a certain space above the mesh plate 513, and the scraper 9 is driven to move the scraper 9 to the other end. During the movement, the solder paste is pushed and flattened. At this time, the uniform feeding operation of the solder paste is completed, the angle between the scraper 713 and the connecting plate 714 is adjusted, and the distance between the bottom plate 711 and the scraper 713 is adjusted to achieve the adjustment of the pressure and angle when the scraper 713 scrapes the solder paste, and the second cylinder 105 is driven to drive the slider 712 to move on the slide rail 2, and drive the scraper assembly 3 to reciprocate on the mesh plate 513. During the unidirectional movement, the solder paste is pushed to the inside of a scraper 9, and as the scraper 713 moves , scrape the solder paste into the holes on the stencil 513, so that the solder paste is firmly attached to the circuit board 512 under the stencil 513, and the solder paste can be pushed into the holes of the stencil 513 by reciprocating pushing, which makes the solder paste tighter and of better quality. After this step is completed, the scraper assembly 3 is moved to one end and the scraper plate 9 is moved down to fit with the stencil 513. At this time, the scraper plate 9 is moved from one end to the other end until the excess solder paste in the scraper assembly 3 is scraped out to the outside, wherein the end plate 8 is rotatably connected between the upper end and the connecting plate 714, and the solder paste can be directly moved out from above the stencil 513, and the two end frames 4 are moved in the opposite direction for a certain distance, so that the two end frames 4 are only connected to the two ends of the circuit board 512, and then the loading rack 6 is set to The upper mesh plate 513 is unloaded vertically to avoid damaging the stacked solder paste. During this process, the scraper 713 and the bottom plate 711 are separated by a large distance up and down, until the mesh plate 513 is completely separated from the circuit board 512, the two end frames 4 are moved in the opposite direction again to separate from the circuit board 512. At this time, the slider 712 is moved on the slide rail 2 to move the scraper assembly 3 out from above the circuit board 512, so that the circuit board 512 can be taken out for the next processing step. By setting the scraper assembly 3 as an inverted C-shaped structure and providing end plates 8 at both ends, the range of direct contact between the solder paste and the air can be greatly reduced, thereby ensuring the quality of the adhesive inside the solder paste. The scraper 9 is provided with two reciprocating scraping movements, making it more convenient to use.
