Description

Technical Field

[0001] This utility model relates to the field of semi-curing technology, specifically to a semi-curing pre-curing device. Background Technology

[0002] Prepreg is a crucial basic material in the electronics manufacturing industry, especially in the printed circuit board (PCB) industry. Its role is to bond copper foil to the core board during the lamination process, while providing insulation and mechanical support. As the "adhesive" of the electronics industry, its technological advancements directly drive the development of PCBs towards high density and high performance. With the explosive growth in demand from emerging fields such as 5G, new energy vehicles, and AI, future breakthroughs in technologies such as high frequency, low loss, and environmental sustainability, as well as increasing the localization rate, will be key to the industry's development.

[0003] Existing semi-curing and pre-curing equipment suffers from insufficient synergy between equipment and materials, resulting in poor coordination. If semi-cured sheets are stored for a long time, dust and other impurities will accumulate on their surface. Existing semi-curing and pre-curing equipment cannot clean the surface, affecting subsequent processing such as laser drilling and reducing bonding quality. Therefore, those skilled in the art provide a semi-curing and pre-curing equipment to solve the problems mentioned in the background art. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are: When this device operates via the second conveyor belt, it generates static electricity through electromagnets, which actively adsorbs dust and easily adsorbed particles from the surface of the semi-cured sheet, reducing the impact of impurities on subsequent processes from the source. This is a non-contact cleaning method that avoids the damage to the material surface that physical wiping may cause. The cleaning effect is uniform and efficient. The sweeping bar on the outside of the fan-shaped plate can accurately hang the dust adsorbed by the second conveyor belt onto the inside of the fan-shaped plate, avoiding secondary dust pollution. The drive auger automatically transports the dust inside the fan-shaped plate to the connecting plate and drops it, eliminating the need for real-time manual cleaning and reducing labor costs. Using the first conveyor belt as the core conveyor, the workpiece is transported sequentially to the cleaning, laminating, drilling, and other workstations. The start and stop are precisely controlled by the control system, seamlessly connecting multiple independent processes to form a highly automated and continuous production line. This greatly reduces the handling and waiting time of workpieces between processes and significantly improves production efficiency. Attached Figure Description

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] Please see Figures 1-2 As shown, this utility model provides a technical solution: a semi-curing and pre-curing device, including a first conveyor belt 1, a plurality of fixed blocks 2 are fixedly connected to the outer side of the first conveyor belt 1, a support frame 3 is fixedly connected to the upper end of the fixed blocks 2, a printed circuit board is provided on the inner side of the support frame 3, a cleaning mechanism 4 for cleaning dust is provided at the upper end of the first conveyor belt 1, and a drilling mechanism 5 for laser drilling is provided at the rear end of the cleaning mechanism 4 and the upper end of the first conveyor belt 1.

[0016] As one implementation method in this embodiment, please refer to Figure 3 As shown, the cleaning mechanism 4 includes a U-shaped plate 41. The lower end of the U-shaped plate 41 is fixedly connected to the first conveyor belt 1. A laminator 42 is installed on the inner side of the U-shaped plate 41. A pressure block 43 is fixedly connected to the output shaft of the laminator 42. The outer side of the pressure block 43 is in contact with the support frame 3. The laminator 42 heats the pressure block 43 to 80~120℃. The U-shaped plate 41 fixes the position of the laminator 42 so that it is above the support frame 3. Its output shaft drives the pressure block 43 to move downward to apply pressure to the semi-cured sheet.

[0017] As one implementation method in this embodiment, please refer to Figures 3-4As shown, two sets of connecting plates 44 are fixedly connected to the front end of the U-shaped plate 41. The lower end of the connecting plate 44 is fixedly connected to the first conveyor belt 1. Three sets of rollers 45 are rotatably connected between the two sets of connecting plates 44. The outer sides of the three sets of rollers 45 are rotatably connected to the second conveyor belt 46. An electromagnet is provided on the outer side of the second conveyor belt 46. A fan-shaped plate 47 is fixedly connected between the two sets of connecting plates 44 at the lower end of the second conveyor belt 46. A sweeping bar 48 is fixedly connected to the outer side of the fan-shaped plate 47. The brush surface of the sweeping bar 48 is in contact with the second conveyor belt 46. One set of rollers 45 drives the second conveyor belt 46 to rotate. The second conveyor belt 46 drives the other two sets of rollers 45 to rotate. When the second conveyor belt 46 rotates, it generates static electricity through the electromagnet, which adsorbs the dust and easily adsorbed particles on the surface of the semi-cured sheet onto its outer side. Then, the dust is hung off by the sweeping bar 48 on the outer side of the fan-shaped plate 47 and slides to the inner side of the fan-shaped plate 47.

[0018] As one implementation method in this embodiment, please refer to Figures 3-4 As shown, a first motor 49 is installed on one side of a set of connecting plates 44. The output shaft of the first motor 49 is fixedly connected to a first synchronous pulley 410. One end of the first synchronous pulley 410 is fixedly connected to a set of rollers 45. A synchronous belt 411 is rotatably connected to the outer side of the first synchronous pulley 410. A second synchronous pulley 412 is rotatably connected to the inner side of the synchronous belt 411. When the first motor 49 operates, its output shaft drives the first synchronous pulley 410 to rotate. The first synchronous pulley 410 drives the set of rollers 45 to rotate. When the first synchronous pulley 410 rotates, it also drives the second synchronous pulley 412 to rotate through the synchronous belt 411.

[0019] As one implementation method in this embodiment, please refer to Figures 3-4 As shown, an auger 413 is provided on the inner side of the sector plate 47. The outer side of the auger 413 is in contact with the sector plate 47. One end of the auger 413 is fixedly connected to the second synchronous wheel 412, and the other end of the auger 413 is rotatably connected to a set of connecting plates 44. The second synchronous wheel 412 drives the auger 413 on the inner side of the sector plate 47 to rotate. The auger 413 transports the dust in the sector plate 47 to one side of the second synchronous wheel 412 by its own rotation.

[0020] As one implementation method in this embodiment, please refer to Figure 5As shown, the drilling mechanism 5 includes a lifting platform 51. The lower end of the lifting platform 51 is fixedly connected to the first conveyor belt 1. A second motor 52 is installed on one side of the lifting platform 51. One end of a lead screw 53 is fixedly connected to the output shaft of the second motor 52. The other end of the lead screw 53 is rotatably connected to the lifting platform 51. A moving block 54 is threadedly connected to the outer side of the lead screw 53. The upper end of the moving block 54 is in contact with the lifting platform 51. A UV laser drilling machine 55 is installed at the lower end of the moving block 54. The lifting platform 51 is driven to descend, which drives the UV laser drilling machine 55 to move. The second motor 52 is driven to operate according to the designed coordinates. Its output shaft drives the lead screw 53 to rotate. The lead screw 53 drives the UV laser drilling machine 55 to move laterally through the moving block 54. The UV laser drilling machine 55 has a high energy density and a wavelength of 200~400nm, which can accurately remove the prepreg material.

[0021] Working principle: In use, the prepreg is placed face down in the cleaning mechanism 4 with the side covered in dust and other impurities. Three sets of rollers 45 support and rotate the upper end of the longest side of the second conveyor belt 46, driving the first motor 49 to rotate. Its output shaft drives the first synchronous pulley 410 to rotate, which in turn drives one set of rollers 45. This set of rollers 45 then drives the second conveyor belt 46, which in turn drives the other two sets of rollers 45. As the second conveyor belt 46 rotates, it generates static electricity through an electromagnet, attracting dust and easily adsorbed particles from the surface of the prepreg to its outer side. The dust is then removed by the sweeping rods 48 on the outer side of the fan-shaped plate 47. The dust slides down to the inside of the sector plate 47. When the first synchronous pulley 410 rotates, it also drives the second synchronous pulley 412 to rotate via the synchronous belt 411. The second synchronous pulley 412 drives the auger 413 inside the sector plate 47 to rotate. The auger 413, through its own rotation, transports the dust inside the sector plate 47 towards one side of the second synchronous pulley 412. When it is transported to one side of a set of connecting plates 44 near the second synchronous pulley 412, it falls off. Users can clean it periodically. Then, the cleaned semi-cured sheet is precisely attached to the upper end of the printed circuit board in the support frame 3, driving the first conveyor belt 1 to rotate and drive the multiple sets of fixing blocks 2 on the outside to rotate. The fixing blocks 2 drive the corresponding fixed support frame 3 to rotate. 2. Due to its narrow width, it can pass smoothly through the bends of the first conveyor belt 1. When the support frame 3 with the prepreg at the upper end overlaps with the pressure block 43, the first conveyor belt 1 stops operating. The laminator 42 heats the pressure block 43 to 80~120℃. The U-shaped plate 41 fixes the position of the laminator 42 so that it is above the support frame 3. Its output shaft drives the pressure block 43 to move downward to apply pressure to the prepreg, causing the epoxy resin in the prepreg to soften and flow, bonding the prepreg to the printed circuit board. Then, the first conveyor belt 1 is driven to operate again, and when the support frame 3 moves to below the drilling mechanism 5, the first conveyor belt 1 stops operating. The lifting platform 51 is driven to descend, driving the U-shaped plate 41 to move downward. The UV laser drilling machine 55 moves, driving the second motor 52 to operate according to the designed coordinates. Its output shaft drives the lead screw 53 to rotate. The lead screw 53 drives the UV laser drilling machine 55 to move laterally through the moving block 54. Utilizing the high energy density and wavelength of 200~400nm of the UV laser drilling machine 55, the semi-cured sheet material is precisely removed, and pre-positioned holes matching the subsequent sintering holes are processed on the semi-cured sheet. After completion, the first conveyor belt 1 is driven to operate again, and sintered conductive copper paste is slowly filled into the pre-positioned holes of the semi-cured sheet processed in the previous step by manual operation. This ensures that the copper paste completely fills the cavity without air bubbles or gaps, realizing interlayer electrical connection. The continuity of the equipment is enhanced through multiple sets of mechanisms.

[0022] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
