Description

Technical Field

[0001] This utility model relates to the field of electronic manufacturing equipment technology, specifically to a laminating equipment for multilayer HDI second-order precision printed circuit boards. Background Technology

[0002] In today's rapidly developing electronic information technology, multilayer HDI (High Density Interconnect) second-order precision printed circuit boards are an indispensable key component in electronic products, and their demand is increasing day by day. With its advantages of high integration, small size, and high performance, multilayer HDI second-order precision printed circuit boards are widely used in various electronic devices such as smartphones, tablets, and high-end servers, which has greatly promoted the development of electronic products towards thinner and lighter, higher-performance directions. However, the manufacturing process of multilayer HDI second-order precision printed circuit boards is extremely complex. Among them, the lamination process is a key step to ensure the quality of the printed circuit board. The main function of the lamination equipment is to press the various layers of the multilayer printed circuit board, such as the inner circuit board and the prepreg, together to form a whole through high temperature and high pressure.

[0003] Most existing equipment uses simple manual counting or simple sensor counting methods. Manual counting is not only inefficient but also prone to human error. Simple sensor counting methods often fail to accurately identify and count high-precision products such as multilayer HDI second-order precision printed circuit boards, leading to chaotic material management during the production process, affecting production progress and cost control. Secondly, in the feeding stage, many traditional equipment lack efficient and precise feeding mechanisms. The raw materials of multilayer HDI second-order precision printed circuit boards are relatively thin and easily damaged. Traditional feeding methods can easily cause the printed circuit boards to shift, jam, or even be damaged during transmission, affecting the subsequent lamination quality. Moreover, traditional equipment cannot achieve precise control of the quantity of materials during the feeding process, failing to meet the dual requirements of production efficiency and product quality in large-scale production. The positioning mechanism is also a major weakness of existing lamination equipment. The lamination of multilayer HDI second-order precision printed circuit boards requires precise alignment between layers; otherwise, it will lead to quality problems such as short circuits and open circuits.

[0010] Beneficial effects

[0011] This invention provides a lamination apparatus for multilayer HDI second-order precision printed circuit boards. Compared with the prior art, it has the following advantages:

[0012] (1) The feeding mechanism consists of a feeding box, a chute, a slider, a first air pump, a first air rod, a pusher plate, and a first groove. The feeding box is used to store the printed circuit boards to be laminated. The chute cooperates with the slider to guide the movement of the pusher plate and ensure that the pusher plate moves smoothly. Secondly, the first air pump provides power and pushes the pusher plate through the first air rod. The first groove on the pusher plate can better fit the printed circuit board and push the printed circuit board out of the feeding box smoothly, realizing automated feeding and improving feeding efficiency and stability. The material counting mechanism consists of a drive motor, a rotating shaft, a first rotating gear, a mounting plate, a rotating shaft, a second rotating gear, a chain, a cam, a fixed plate, a rotating rod, a pressing plate, a return spring, a baffle plate, a cavity, a connecting rod, and a pusher plate. The drive motor drives the rotating shaft and the first rotating gear to rotate. The chain transmission makes the second rotating gear and the rotating shaft rotate synchronously. The cam rotates with the rotating shaft and periodically presses the pressing plate. The pressing plate drives the rotating rod to rotate, making the baffle plate move up and down. The oscillating mechanism enables intermittent feeding of printed circuit boards. When the cam intermittently presses against the extrusion plate, the material being fed causes the baffle plate to lower slightly, facilitating material counting. After one rotation of the cam, the feeding of a single material is complete, triggering a return spring that resets the baffle plate and rotating rod. The positioning mechanism consists of a placement platform, a receiving slot, a second air pump, a second air rod, a clamping plate, a copper plate positioning plate, a printed circuit board positioning plate, a second groove, a telescopic rod, and an adjusting plate. The placement platform holds the printed circuit boards to be laminated. The second air pump provides power, and the second air rod pushes the clamping plate. The copper plate positioning plate and the printed circuit board positioning plate on the clamping plate precisely position the copper plate area and the entire printed circuit board, ensuring accurate positioning of the printed circuit board on the placement platform. The second groove provides installation space for the telescopic rod and the adjusting plate. The telescopic rod moves the adjusting plate up and down, preventing obstruction when material exits the conveyor belt. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1:

[0021] Please see Figures 1-5 As shown in the figure, this embodiment proposes a laminating equipment for a multilayer HDI second-order precision printed circuit board. The printed circuit board laminating equipment includes: a mounting table 1, and the upper surface of the mounting table 1 is provided with a feeding mechanism, a material counting mechanism and a positioning mechanism from back to front.

[0022] The feeding mechanism includes feeding boxes 2. Three feeding boxes 2 are fixedly connected to the upper surface of the mounting platform 1. The inside of each feeding box 2 is provided with a sliding groove 201. A slider 202 is slidably connected inside the sliding groove 201. A first air pump 203 is fixedly connected to the upper surface of the mounting platform 1. A first air rod 204 is fixedly connected to the output end of one side of the first air pump 203. A pusher plate 205 is fixedly connected to the output end of the first air rod 204. The lower surface of the pusher plate 205 is slidably connected to the upper surface of the slider 202. A first groove is provided inside the pusher plate 205. 206. When the first air pump 203 is started, compressed air pushes the first air rod 204 connected to one of its output ends to extend or retract. The output end of the first air rod 204 is fixedly connected to the pusher plate 205, thereby transmitting the power generated by the air pump to the pusher plate 205, causing the pusher plate 205 to move linearly. The first groove 206 cooperates with the connecting rod 3014 of the material counting mechanism and the pusher plate 3015, so that when the material is sent out of the feeding box 2, the pusher plate 3015 assists the pusher plate 205 in pushing the material.

[0023] Preferably, a mounting groove 101 is provided on one side of the upper surface of the mounting platform 1. A conveyor belt 102 is movably connected inside the mounting groove 101. Two pairs of support columns 103 are fixedly connected to the upper surface of the mounting platform 1. A top plate 104 is fixedly connected to the upper surface of the support columns 103. A hydraulic tank 105 is fixedly connected to the upper surface of the top plate 104. Guide rods 106 are movably connected to the left and right sides inside the top plate 104. A pressing plate 107 is fixedly connected to the output end of the lower surface of the hydraulic tank 105. When lamination is required, the output end of the lower surface of the hydraulic tank 105 pushes the pressing plate 107 downward. The guide rods 106 movably connected to the left and right sides inside the top plate 104 serve a guiding function to ensure that the pressing plate 107 remains vertical during downward movement and does not deviate.

[0024] Preferably, the material counting mechanism includes a drive motor 3. The drive motor 3 is fixedly connected to the upper surface of the mounting platform 1, and the drive motor 3 is positioned near the feeding box 2. A rotating shaft 301 is fixedly connected to the output end of the drive motor 3. A first rotating gear 302 is fixedly connected to the outer wall of the rotating shaft 301. A mounting plate 303 is fixedly connected to the upper surface of the mounting platform 1, and the mounting plate 303 is positioned on the left and right sides of the feeding box 2. A rotating shaft 304 is movably connected inside a pair of mounting plates 303. A second rotating gear 305 is fixedly connected to the outer wall of the rotating shaft 304. The outer walls of the second rotating gear 305 and the first rotating gear 302 are connected to each other. A chain 306 is fixedly connected via teeth. Cams 307 are fixedly connected to the left and right sides of the outer wall of the rotating shaft 304. A fixing plate 308 is fixedly connected to one side of each of the pair of mounting plates 303. A rotating rod 309 is movably connected inside the fixing plate 308. A pressing plate 3010 is fixedly connected to the upper surface of the rotating rod 309. A return spring 3011 is movably connected to the outer wall of the rotating rod 309. A baffle plate 3012 is fixedly connected to the lower surface of each of the pair of rotating rods 309. A cavity 3013 is opened on the front of the feeding box 2. A connecting rod 3014 is movably connected inside the cavity 3013. A push plate 301 is fixedly connected to the outer wall of the connecting rod 3014. 5. The output end of the drive motor 3 drives the rotating shaft 301 to rotate, thereby causing the first rotating gear 302 on the rotating shaft 301 to rotate synchronously. The first rotating gear 302 transmits power to the second rotating gear 305 on the rotating shaft 304 through the chain 306, causing the rotating shaft 304 to rotate. The cams 307 fixed on the left and right sides of the outer wall of the rotating shaft 304 rotate with the rotating shaft 304. When the cams 307 rotate, their contours periodically press the extrusion plate 3010, causing the extrusion plate 3010 to move downward. The extrusion plate 3010 drives the rotating rod 309 to rotate within the fixed plate 308. The baffle plate 3012 on the lower surface of the rotating rod 309 rotates with the rotating rod 309. The cam 307 swings up and down. When the baffle plate 3012 swings upward, it blocks the printed circuit board from passing through. When the baffle plate 3012 swings downward, the printed circuit board can pass through, thus realizing the intermittent feeding of the printed circuit board. During the intermittent squeezing of the extrusion plate 3010 by the cam 307, each squeezing causes the baffle plate 3012 to drop down a little, allowing a printed circuit board to pass through. When the cam 307 rotates one revolution, it means that the feeding process of a single material is over. At this time, the extrusion plate 3010 is no longer squeezed by the cam 307. Under the elastic force of the return spring 3011 movably connected to the outer wall of the rotating rod 309, the rotating rod 309 and the baffle plate 3012 will return to their initial positions.

[0025] Preferably, the positioning mechanism includes a placement platform 4, which is fixedly connected to the upper surface of the mounting platform 1 and positioned below the pressing plate 107. A storage groove 401 is formed inside the pair of placement platforms 4. A second air pump 402 is fixedly connected to the upper surface of the mounting platform 1. A second air rod 403 is fixedly connected to one output end of the second air pump 402. A clamping plate 404 is fixedly connected to one output end of the second air rod 403. Copper plate positioning plates 405 are fixedly connected to both sides of the clamping plate 404. A printed circuit board positioning plate 406 is fixedly connected to the middle of the clamping plate 404. A second groove 407 is formed on the upper surface of the mounting platform 1 and positioned on one side of the placement platform 4. Telescopic extension devices are movably connected to the left and right sides inside the second groove 407. The telescopic rod 408 has an adjustable plate 409 fixedly connected to its output end. When the second air pump 402 is started, the second air rod 403 connected to its output end moves in extension and retraction under the action of compressed air. The output end of one side of the second air rod 403 is fixedly connected to the clamping plate 404, thereby transmitting the power generated by the air pump to the clamping plate 404 and pushing the clamping plate 404 to move in a straight line. By controlling the extension and retraction of the telescopic rod 408, the adjustable plate 409 can be driven to move up and down. When the material is discharged from the conveyor belt 102, the position of the adjustable plate 409 can be flexibly adjusted according to the size of the material and the height of the conveyor belt 102 so that it will not block the normal discharge of the material and ensure that the material can smoothly and unobstructedly enter the positioning area, thus ensuring the continuity and efficiency of the production process.

[0026] When this utility model is in use, the first air pump 203 is started, the first air pump 203 drives the first air rod 204 to extend, and pushes the pusher plate 205 to move forward along the slide groove 201 in the feeding box 2. The pusher plate 205 pushes the printed circuit board forward through its internal first groove 206. During the pushing process, the pusher plate 3015 works in conjunction with the pusher plate 205 to help the printed circuit board be smoothly delivered from the feeding box 2. The drive motor 3 starts, driving the rotating shaft 301 to rotate. The first rotating gear 302 on the rotating shaft 301 rotates accordingly, driving the second rotating gear 305 on the rotating shaft 304 to rotate through the chain 306, thus causing the rotating shaft 304 to rotate synchronously. The cam 307 on the outer wall of the rotating shaft 304 rotates with the rotating shaft 304, periodically squeezing the extrusion plate 3010, causing the extrusion plate 3010 to drive the rotating rod 309 to rotate within the fixed plate 308, thereby causing the baffle plate 3012 to swing up and down, realizing the intermittent feeding of the printed circuit board. Each time the cam 307 squeezes and causes the baffle plate 3012 to drop once, a printed circuit board passes through, and the counting system records once, completing the material counting. When the cam 307 rotates once, the feeding process of a single material ends, and the extrusion plate... 3010 is no longer compressed. Under the elastic force of the return spring 3011, the rotating rod 309 and the baffle plate 3012 reset, preparing for the next feeding and counting. The printed circuit board is conveyed by the conveyor belt 102 and enters the positioning area of ​​the placement table 4. The second air pump 402 is started, which drives the second air rod 403 to extend, pushing the clamping plate 404 to move towards the printed circuit board. The copper plate positioning plates 405 on the left and right sides of the clamping plate 404 position the copper plates related to the printed circuit board. The printed circuit board is positioned by the middle printed circuit board positioning plate 406 to ensure the accurate position of the printed circuit board and its copper plate, preparing for the subsequent lamination operation. After the printed circuit board is positioned, the pressing plate 107 moves downward under the drive of the hydraulic box 105 to perform the lamination operation on the printed circuit board placed on the placement table 4. After lamination is completed, the pressing plate 107 rises and resets, releasing the pressure on the printed circuit board, releasing the clamping plate 404, and taking the laminated product out of the placement table 4.
