[0002] In the electronic manufacturing industry, a PCB (printed circuit board) is one of the core components indispensable in the electronic industry, which provides an electrical connection platform between electronic components for various electronic devices, and is mainly formed by processing multiple core boards through etching, fusion, riveting, drilling, plating, assembly and other processes. When the fusion process is performed, the multiple core boards and PP semi-cured adhesive sheets are alternately stacked, and the stacked multiple core boards are laminated by using a fusion device, so that the PP semi-cured adhesive sheet is melted by using a high-temperature and high-pressure environment, and the multiple core boards and the conductive layer are bonded together. However, in the process of laminating and fusing the stacked core boards by using the fusion device, the PP semi-cured adhesive sheet is heated and melted, and the melted PP semi-cured adhesive sheet flows and fills between the core boards. When the melted PP semi-cured adhesive sheet has strong fluidity, it will flow to the workbench surface and solidify into adhesive droplets or / and adhesive blocks on the surface of the workbench. In the subsequent PCB lamination and fusion process, the adhesive points or / and adhesive blocks remaining on the workbench surface will cause defects such as adhesive marks and black blocks on the surface of the PCB, and in severe cases, will cause serious quality problems such as creases, cracks and adhesive blocks on the PCB.

The separation part 20 comprises a shell 21 and a separation knife 22. The shell 21 is threadedly connected to the outer side of the threaded rod 15, and the shell 21 and the guide rod 14 are slidably connected. A plurality of air outlets are uniformly formed on the lower end of the shell 21. The separation knife 22 is assembled on the lower end inside the shell 21. One end of the shell 21 is provided with a separation blade opening, and the separation blade opening is in close contact with the top of the sliding table 11. A heating part 30 is assembled inside the shell 21, and the air outlet is matched with the heating part 30. The collecting part 40 is assembled in the inside of the shell 21, and can collect the glue on the surface of the sliding table 11. Wherein, the heating part 30 can heat the glue on the upper end of the sliding table 11 to a softened state.

[0020] Here, the fusion module is a mature technology, which can heat the staggered and stacked PP prepreg and core plate through electromagnetic heating. The copper foil in the core plate is heated by electromagnetic heating to heat the PP prepreg, so that the resin in the PP prepreg melts and flows and fills between the multiple core plates. By applying a predetermined pressure to the core plate, the multiple core plates are bonded together to achieve the purpose of laminating and fusing the multiple core plates.

[0021] Further, the outer side of the two threaded rods 15 located at both ends of the double-shaft motor 13 is provided with external threads, and the external threads on the outer sides of the two threaded rods 15 are opposite in rotation direction.

[0022] Further, the inside of the fusion station main body 10 is provided with a control module, and the double-shaft motor 13, the fusion module and the control module, and the heating part 30 and the control module are connected with each other.

[0023] In this embodiment, when the PCB is laminated and fused, the stacked PP prepreg and core board are collectively transported to the surface of the sliding table 11, the main body 10 of the fusion station is started to laminate and fuse the PP prepreg and the core board, and during the fusion process, the PP prepreg in a molten state is used to bond the plurality of core boards. After the laminated fusion is completed, the PP prepreg in a molten state flows to the surface of the sliding table 11 to form a glue point or / and a glue block. The biaxial motor 13 is started to separate the glue point or / and the glue block remaining on the surface of the sliding table 11. The biaxial motor 13 is connected to the threaded rod 15 through the fixed connection, so that the biaxial motor 13 drives the threaded rod 15 to rotate. The threaded rod 15 is connected to the housing 21 through the threaded connection, and the guide rod 14 is connected to the housing 21 through the sliding connection, so that the threaded rod 15 drives the housing 21 to move on the upper end of the sliding table 11. The heating part 30 and the collecting part 40 are synchronously moved by the housing 21. The heating part 30 and the collecting part 40 are started. After the heating part 30 is operated, the heating part 30 heats the glue point or / and the glue block, so that the glue point or / and the glue block is in a softened state. At the same time, the separation knife 22 is arranged in the interior of the housing 21, and the separation knife 22 is synchronously moved by the housing 21. The separation blade on the housing 21 is in contact with the top of the sliding table 11, so that the separation knife 22 separates the glue point or / and the glue block in a softened state remaining on the surface of the sliding table 11. At the same time, the separation state of the glue point or / and the glue block is collected by the collecting part 40, so as to avoid the quality problems of the subsequent PCB, such as glue marks, black spots, creases and cracks, caused by the glue point or / and the glue block remaining on the surface of the sliding table 11, and improve the yield of the PCB.

[0024] Further, the frequency of cleaning the surface of the sliding table 11 by the separation part 20 can be adjusted according to actual production needs and glue overflow. It can be cleaned after each laminated fusion, or it can be cleaned regularly. Herein, no specific limitation is made.

[0025] Secondly, please refer to Figures 4 to 8 The interior of the housing 21 is provided with a separation cavity 27 and a heating cavity 28. The heating part 30 is matched with the heating cavity 28, and a plurality of air outlets are arranged at the lower end of the heating cavity 28. The separation part 20 further comprises a first shaft 23, a sleeve 24, a linkage arm 25 and a tension spring 26. The first shaft 23 is fixed in the interior of the separation cavity 27. The sleeve 24 is rotatably connected to the outer side of the first shaft 23, and the sleeve 24 is connected with the separation knife 22. The linkage arm 25 is fixed to one end of the sleeve 24 away from the separation knife 22. The tension spring 26 is arranged between the linkage arm 25 and the housing 21. In the initial state, the tension spring 26 is in a stretched state.

[0026] Further, please refer to Figure 9As shown, the outer side of the sleeve 24 is also fixed with a plurality of flange plates 29, the inner side of the flange plate 29 is equipped with a plurality of fastening screws, the separating knife 22 is fixed to the outer side of the sleeve 24 through the fastening screws, through the scheme, when the separating edge of the separating knife 22 is worn and the cleaning effect is reduced, the separating knife 22 can be conveniently replaced to ensure the cleaning effect of the glue points or / and glue blocks.

[0027] In this embodiment, since the initial state is that the tension spring 26 is in a stretched state, the linkage arm 25 is pulled to rotate in the direction of contraction by the tension spring 26, the sleeve 24 is driven to rotate by the linkage arm 25 through the fixed connection of the linkage arm 25 and the sleeve 24, the separating knife 22 is driven to rotate by the sleeve 24 since the sleeve 24 is connected with the separating knife 22, so that the separating knife 22 and the sliding table 11 can be closely attached to improve the surface cleaning effect of the sliding table 11.

[0028] Secondly, please refer to Figures 6 to 8 The heating part 30 includes a heating pipe 31, a fan 32 and a temperature sensor 33, the heating pipe 31 is fixed in the inner side of the heating cavity 28, the fan 32 is fixed to the upper end of the inner side of the heating cavity 28, a plurality of air inlet holes are arranged on the upper end of the heating cavity 28, and the air inlet holes are matched with the fan 32, and the fan 32 is fixed to one side of the inner side of the heating cavity 28 and located at the lower end of the heating pipe 31.

[0029] Further, the heating pipe 31, the fan 32 and the temperature sensor 33 are electrically connected with the control module through wires.

[0030] In this embodiment, when the glue points or / and glue blocks on the surface of the sliding table 11 are cleaned, the double-shaft motor 13 is started, the threaded rod 15 is driven to rotate by the double-shaft motor 13, the shell 21 and the heating part 30 are synchronously moved by the threaded rod 15, the heating pipe 31 is started, the heating pipe 31 releases heat to heat the gas in the heating cavity 28, the fan 32 is started, the gas in the heating cavity 28 is driven to flow by the fan 32, the gas heated by the heating pipe 31 is blown to the glue points or / and glue blocks on the surface of the sliding table 11 through the air outlet holes, the glue points or / and glue blocks are heated, the glue points or / and glue blocks are in a softened state, and the softened glue points or / and glue blocks are cleaned by the separating knife 22, at the same time, the temperature of the gas in the heating cavity 28 is monitored by the temperature sensor 33, the temperature in the heating cavity 28 can be prevented from being too high, the power of the heating pipe 31 can be reduced when the temperature in the heating cavity 28 is too high, the power of the heating pipe 31 can be increased when the temperature in the heating cavity 28 does not reach the preset temperature, and the energy utilization rate is improved.

[0031] Secondly, the lower end of the heating cavity 28 is fixed with a heat collecting groove 34, and the cross-sectional shape of the heat collecting groove 34 is inverted T-shaped.

[0032] In this embodiment, the arrangement of the heat collecting groove 34 can guide and collect the high-temperature gas flowing out of the heating cavity 28, so that the heating part 30 can quickly heat the glue dots or / and glue blocks at the lower end of the heat collecting groove 34, and the softening speed of the glue dots or / and glue blocks is improved.

[0033] Please refer again to Figures 6 to 7 As shown, the collecting part 40 includes a plurality of shunt pipes 41, a collecting groove 42, and a plurality of cutting knives 43. The plurality of shunt pipes 41 are fixed to the upper end of the separation cavity 27, and the upper end of the shunt pipe 41 penetrates the separation cavity 27. The collecting groove 42 is fixed to the lower end of the plurality of shunt pipes 41. The plurality of cutting knives 43 are respectively fixed to the upper end of the separation knife 22 away from one end of the tension spring 26. The upper end of the cutting knife 43 is obliquely provided with a cutting edge.

[0034] It should be noted that the device is also matched with a pneumatic module. The input end of the pneumatic module is connected with the shunt pipe 41 through an elastic air pipe. After the pneumatic module is started, a negative pressure space is formed in the collecting groove 42.

[0035] In this embodiment, the double-shaft motor 13 drives the shell 21, the separation knife 22, the heating part 30, and the collecting part 40 to move on the upper end of the sliding table 11. The glue dots or / and glue blocks on the surface of the sliding table 11 are heated to a softened state by the heating part 30, and the glue dots or / and glue blocks in the softened state are separated from the surface of the sliding table 11 by the separation knife 22. At the same time, the glue dots or / and glue blocks with a large size after separation will be cut after contacting the cutting knife 43. The pneumatic module is started, a negative pressure space is formed in the collecting groove 42, and the gas in the separation cavity 27 and the cut glue dots or / and glue blocks are sequentially collected into the pneumatic module through the collecting groove 42, the shunt pipe 41, and the elastic air pipe, so as to avoid the glue dots or / and glue blocks in the separation state from being retained on the surface of the separation knife 22. At the same time, the glue dots or / and glue blocks after separation are cut by the cutting knife 43, so as to reduce the size of the glue dots or / and glue blocks and avoid the glue dots or / and glue blocks with a large size from causing the shunt pipe 41, the elastic air pipe, or the starting module to be blocked.

[0036] Please refer again to Figure 8 and Figure 11 As shown, the second shaft rod 44 is rotatably connected to the upper end of the separation knife 22 in the separation cavity 27. The second shaft rod 44 is uniformly provided with a plurality of limiting rods 45 on the outer side. The straight gear 46 is fixed to one end of the outer side of the second shaft rod 44 and located on the outer side of the shell 21. The toothed rack 47 is fixed to the side of the baffle 12 close to the shell 21, and the straight gear 46 and the toothed rack 47 are in meshing connection.

[0037] It is worth mentioning that the minimum distance between the second shaft rod 44 and the separation knife 22 is slightly greater than the length of the limiting rod 45.

[0038] In this embodiment, the start of the double-shaft motor 13 drives the shell 21, the separating knife 22, the heating part 30 and the collection part 40 to move on the upper end of the slide table 11. The glue points or / and glue blocks on the surface of the slide table 11 are heated by the heating part 30, and the softened glue points or / and glue blocks are separated from the surface of the slide table 11 by the separating knife 22. The separated glue points or / and glue blocks move along the surface of the separating knife 22. At the same time, when the shell 21 moves, the rotation connection between the shell 21 and the second shaft rod 44 enables the shell 21 to drive the second shaft rod 44 to move synchronously. The fixed connection between the second shaft rod 44 and the straight gear 46 enables the second shaft rod 44 to drive the straight gear 46 to move. Since the straight gear 46 and the rack 47 are in meshing connection, the straight gear 46 rotates when it moves. The straight gear 46 drives the second shaft rod 44 and the limiting rod 45 to rotate. When the limiting rod 45 contacts the softened glue blocks on the upper end of the separating knife 22, it penetrates into the glue blocks to limit the glue blocks and drive them to move along the surface of the separating knife 22. The dividing knife 43 divides the large-size glue blocks to avoid the failure of the dividing knife 43 to cut the large-size glue blocks.

[0039] Please refer again to Figure 10 As shown, a plurality of U-shaped grooves 48 are uniformly arranged on one side of the collection groove 42, and the U-shaped grooves 48 are matched with the limiting rods 45.

[0040] In this embodiment, after the limiting rod 45 penetrates into the softened glue blocks and divides them, the U-shaped grooves 48 can separate the glue blocks adhered to the limiting rods 45, avoiding the adhesion of the divided glue blocks to the upper end of the limiting rods 45.

[0041] Please refer again to Figure 3 As shown, the support plate 16 is fixed inside the fusion station main body 10 and between the plurality of slide tables 11. The support plate 16 is attached to the slide table 11, and the upper end of the support plate 16 is located between the bottom of the shell 21 and the upper end of the slide table 11.

[0042] It should be noted that when the separating knife 22 and the slide table 11 are separated, the upper end of the support plate 16 is higher than the upper end of the slide table 11. The rotation of the separating knife 22 driven by the support plate 16 can increase the stretching amount of the tension spring 26. At the same time, the separating edge of the separating knife 22 is attached to the upper end of the support plate 16.

[0043] In this embodiment, when the stacked PP prepreg and core plate are placed on the surface of the sliding table 11 for laminating and fusing, the two-axis sliding table module drives the sliding table 11 to move, so that the sliding table 11 and the separating knife 22 are separated. In order to avoid separation during laminating and fusing, the tension spring 26 is retracted to drive the separating knife 22 to rotate downward. By providing the supporting plate 16, the separating blade of the separating knife 22 can be prevented from being lower than the upper end of the sliding table 11, thereby avoiding the separating blade of the separating knife 22 from being unable to adhere to the upper end of the sliding table 11 again.

[0044] The working principle of the present application is as follows: In the process of laminating and fusing the PCB, the stacked PP prepreg and core plate are transported to the surface of the sliding table 11, and the fusing station main body 10 is started to laminate and fuse the PP prepreg and core plate. During the fusing process, the molten PP prepreg is used to bond multiple core plates. After the laminating and fusing process is completed, the molten PP prepreg flows to the surface of the sliding table 11 to form a glue point or / and a glue block. The biaxial motor 13 is started to separate the glue point or / and the glue block remaining on the surface of the sliding table 11. The biaxial motor 13 is fixedly connected with the threaded rod 15, so that the biaxial motor 13 drives the threaded rod 15 to rotate. The threaded rod 15 is threadedly connected with the housing 21 and slidably connected with the guide rod 14, so that the threaded rod 15 drives the housing 21 to move on the upper end of the sliding table 11. The housing 21 drives the heating part 30 and the collecting part 40 to move synchronously. The heating part 30 and the collecting part 40 are started. After the heating part 30 is operated, the heating tube 31 and the fan 32 cooperate to heat the glue point or / and the glue block, so that the glue point or / and the glue block is in a softened state. Since the separating knife 22 is arranged in the interior of the housing 21, the housing 21 drives the separating knife 22 to move synchronously. Since the separating blade on the housing 21 adheres to the top of the sliding table 11, the housing 21 separates the glue point or / and the glue block in a softened state remaining on the surface of the sliding table 11. The limiting rod 45 drives the separated glue point or / and glue block to move on the surface of the separating knife 22. The dividing knife 43 divides the glue point or / and the glue block on the surface of the separating knife 22. The pneumatic module is started, so that the divided glue point or / and glue block passes through the collecting groove 42, the shunt pipe 41 and the telescopic air pipe in sequence and is collected in the starting module, thereby achieving the purpose of removing the glue point or / and the glue block remaining on the surface of the sliding table 11.
