Description

Technical Field

[0001] The invention belongs to the technical field of PCB hot pressing equipment, and particularly relates to a novel PCB hot pressing device. Background Art

[0002] PCB (Printed Circuit Board), whose Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. Because it is made using electronic printing technology, it is called a "printed" circuit board.

[0003] In conventional PCB hot pressing, the material is generally placed on a bottom mold first, then hot pressed, and finally the hot-pressed PCB board is removed. However, since the hot pressing head rises slowly after hot pressing, workers need to pick up the material by hand in order to quickly remove the material. This can easily cause accidental scratches or crushing during the removal process, which is not conducive to worker operation. In addition, since a high temperature is required to melt the solder on the surface of the PCB board during hot pressing, a lot of heat is generated around the hot press. In particular, after the PCB board is hot pressed, the surface temperature of the hot pressing head and the PCB board are both high. If the worker picks up the material directly by hand, it may cause burns to the worker's hands. In addition, the operation of removing and placing the material is cumbersome, resulting in low production efficiency and failing to meet the needs of efficient production. Summary of the Invention

[0004] The purpose of the present invention is to provide a novel PCB hot pressing device that can automatically remove the hot-pressed PCB boards after the PCB boards are hot-pressed, eliminating the need for manual material removal. This improves production efficiency and prevents workers from accidentally getting burned or crushed by manually removing the materials.

[0005] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows:

[0006] A novel PCB board hot pressing device comprises a base, a frame, a hydraulic cylinder, a tension and pressure sensor, a connecting plate, a heating mechanism, an upper mold, a control panel and a lower mold, wherein the control panel is electrically connected to the outside world, the control panel is electrically connected to the hydraulic cylinder, the heating mechanism and the tension and pressure sensor, the lower mold is arranged at the upper end of the base and corresponds to the upper mold, an assembly cavity is provided in the lower mold, a fixed block is provided in the middle of the assembly cavity, a first slide bar is fixedly connected between the fixed block and the front inner wall of the assembly cavity, the first slide bar is slidably equipped with a slide plate, the first slide bar sleeve is provided with a first return spring located between the slide plate and the fixed block, a pushing assembly is provided on the upper side of the slide plate, the slide plate is provided with a first stabilizing assembly, and unloading mechanisms are provided on both sides of the slide plate, the unloading mechanism comprises an extension plate fixedly connected to the slide plate and a movable groove opened on the lower mold, and an arc groove is provided in the middle position of the lower wall of the movable groove. The lowest point of the arc groove matches the front wall of the fixed block, and a pushing member is slidably assembled in the movable groove, and the pushing member includes an assembly block, and limit assemblies are provided on the left and right sides of the assembly block, and the assembly block has a cavity, and the upper and lower ends of the assembly block are provided with through holes connected to the cavity, and a mounting block is slidably assembled in the cavity, and the upper and lower ends of the mounting block are respectively provided with a lock tongue and a roller extending out of the cavity, and the lock tongue is provided with an inclined surface on the side away from the extension plate, and the mounting block is provided with a telescopic assembly matching the lock tongue, and the mounting block is provided with a second stabilizing assembly matching the cavity, and the front side of the assembly block is provided with a first cable, and the other end of the first cable is connected to a reset assembly, and the rear side of the assembly block is fixedly connected to the second cable extending out of the movable groove, and the rear side of the connecting plate is provided with two connecting strips, and the two connecting strips are respectively fixedly connected to the two second cables, and the rear side of the base is provided with a material connecting assembly.

[0007] According to the technical solution of the present invention, in the initial state, the output shaft of the hydraulic cylinder is not extended, so that the upper mold and the lower mold are not pressed together, and the pushing assembly is located on the front side of the upper mold, and the pushing member is located on the front side of the extension plate; when hot pressing is performed, the workpiece to be processed is placed on the upper side of the lower mold, and then the hydraulic cylinder is started through the control panel. At this time, the output shaft of the hydraulic cylinder extends to push the connecting plate downward, and then pushes the upper mold downward until it is pressed together with the lower mold.

[0008] When the hot pressing process is completed, the output shaft of the hydraulic cylinder is gradually retracted, causing the connecting plate to move upward gradually, thereby gradually pulling out the two second cables from the movable groove. When the second cable is gradually pulled out of the movable groove, the second cable will drive the pushing member to move together; when the pushing member moves, the roller at the lower side of the mounting block rolls accordingly, and the locking tongue at the upper side of the mounting block is against the extension plate, and then gradually pushes the extension plate to move with the movement of the connecting plate, thereby causing the slide plate to gradually move, and then the pushing assembly connected to the slide plate gradually moves to the rear side of the lower mold, so that the material on the upper side of the lower mold is gradually pushed to the rear side of the lower mold until it falls into the material receiving assembly due to gravity. When the pushing member continues to move until it gradually moves to the arc groove, due to the second The function of the stabilizing component is that when the roller continues to move along the trajectory of the arc-shaped groove, the mounting block will gradually move downward, so that the lock tongue on the upper side of the mounting block is gradually retracted into the cavity of the assembly block, and then the lock tongue gradually disengages from the extension plate, until the roller moves to the lowest point of the arc-shaped groove, and the lock tongue is completely disengaged from the extension plate. At this time, due to the rebound of the first return spring, the slide plate will be pushed to move to the front side of the lower mold and reset, and then the pushing component will be reset to the front side of the lower mold. Since the lowest point of the arc-shaped groove matches the front wall surface of the fixed block, it can prevent the slide plate from being blocked by the fixed block when the lock tongue has not completely disengaged from the extension plate, causing conflict between components. The limiting component can make the movement of the pushing member smoother.

[0009] When the pushing component is reset, the connecting plate will continue to move up until it is reset, and the pushing member will continue to move to the rear side of the lower mold until the connecting plate stops moving. When the upper mold stops moving and the mold is fully opened, the new material to be processed can be placed on the upper side of the lower mold for a new hot pressing process. Since the pushing component has been reset in advance during the process of the upper mold rising and resetting, it will not affect the placement of the new material. When the upper mold is pressed down again, the connecting plate will move down again. Since the first cable is connected to the reset component, and the first cable is connected to the pushing member, and the pushing member is at the rear side of the lower mold at this time, when the connecting plate moves down, the reset component is reset. The assembly will pull the first cable to move toward the front side of the lower mold, thereby causing the pusher to gradually move toward the front side of the lower mold, so that the second cable is also pulled into the movable groove. When the pusher gradually moves to the reset extension plate, the lock tongue of the pusher will be squeezed with the extension plate, and because the roller fits with the lower wall of the movable groove and cannot drop, the lock tongue is pushed back into the cavity of the assembly block through the guidance of the inclined surface. At this time, the telescopic assembly is compressed. When the pusher continues to move until it passes the extension plate, the telescopic assembly rebounds to push the lock tongue out, thereby resetting the pusher, so that when the mold is opened again, new material can be pushed into the receiving assembly again.

[0010] The present invention uses a unloading mechanism to quickly unload materials during the mold opening process without manual operation, avoiding manual operation that is prone to scratching, pressing, and scalding, thereby improving the safety of hot pressing processing. At the same time, it can automatically reset after unloading without affecting the loading of new materials, thereby greatly improving production efficiency and reducing the unloading operations required for hot pressing processing.

[0011] It is further defined that the telescopic assembly includes a stepped hole provided in the mounting block, a second return spring fixedly connected to the bottom wall of the stepped hole, the other end of the second return spring fixedly connected to a limit block matching the stepped hole, and the upper end of the limit block fixedly connected to the lock tongue. With this structure, when the lock tongue is squeezed, the guide of the inclined surface will cause the lock tongue to move downward, thereby causing the limit block to move toward the lower side of the stepped hole. At this time, the second return spring is compressed. When the lock tongue passes over the extension plate, the second return spring rebounds and pushes out the limit block, thereby resetting the lock tongue. The limit block can prevent the lock tongue from being disconnected from the stepped hole.

[0012] It is further defined that the second stabilizing assembly includes limit sliders located on the left and right sides of the mounting block and fixedly connected to the mounting block, two limit sliders are provided between the upper and lower inner walls of the cavity, and are matched with the two limit sliders respectively. The limit sliders are slidably assembled with the limit sliders, and the two limit sliders are each sleeved with a third return spring located between the upper inner wall of the cavity and the upper end of the limit slider. With this structure, when the pusher moves to the arc-shaped groove, the roller moves along the trajectory of the arc-shaped groove. Due to the action of the third return spring, the limit slider will gradually move downward with the movement of the pusher, thereby ensuring that the roller always fits in the arc-shaped groove. The limit slider can make the movement of the limit slider more stable, and the limit slider can prevent the mounting block from being disconnected from the cavity.

[0013] The push assembly further defines a push groove and a push plate. The movable groove is located on the upper side of the lower mold and is connected to the assembly cavity. The lower side of the push plate passes through the push groove and is connected to the upper side of the slide. With this structure, the push plate can move within the push groove along with the movement of the slide, thereby gradually pushing the material into the receiving assembly.

[0014] Furthermore, the second cable sleeve is provided with a fourth return spring positioned between the movable slot and the assembly block, and a guide wheel matching the second cable is provided on the rear side of the lower die. This structure allows the fourth return spring to exert a more effective thrust when the pusher returns to the front side of the lower die, preventing the locking tongue from being unable to pass over the extension plate due to insufficient return force. The guide wheel guides the second cable, ensuring its stable movement.

[0015] It is further defined that the reset assembly includes two protrusions fixedly connected to the inner wall of the movable groove, a winding wheel is rotatably mounted between the two protrusions, the first cable is connected to the winding wheel, and the winding wheel is provided with a coil spring. With this structure, the first cable is connected to the winding wheel, and when the pusher moves toward the rear side of the lower mold, the winding wheel rotates under the tension and releases the first cable, at which time the coil spring rewinds. When the connecting plate moves downward, the tension on the rear side of the lower mold disappears, at which time the coil spring rewinds and retracts the first cable, thereby pulling the pusher to reset.

[0016] The first stabilizing assembly further comprises two first stabilizing rods arranged parallel to the first slide rod and located on the left and right sides of the first slide rod, respectively. The two first stabilizing rods are located between the fixed block and the front inner wall of the assembly cavity and are slidably assembled with the slide plate. This structure can make the movement of the slide plate more stable.

[0017] It is further defined that the limiting assembly includes a T-shaped slot opened on the side wall of the movable groove, and the assembly block is fixedly connected to a T-shaped slider matching the T-shaped slot. Such a structure can make the movement of the assembly block more stable.

[0018] The material receiving assembly further defines a material receiving frame that includes a guide ramp located at the rear side of the lower mold and a material receiving frame that matches the guide ramp. With this structure, the guide ramp can guide the material into the material receiving frame, and the material receiving frame can effectively store the hot-pressed material for subsequent processing.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. Through the cooperation of the first cable and the connecting plate, the pusher can be pulled when the mold is opened, so that the pusher assembly can automatically unload the material that has been hot-pressed on the upper side of the upper mold, eliminating the need for manual unloading. This avoids the risk of scratching, pressing, and scalding during manual unloading, making the processing operation safer and greatly improving production efficiency.

[0021] 2. Through the cooperation of the first return spring, arc groove, roller, telescopic assembly and the second stabilizing assembly, the pushing assembly can be automatically reset after the material is unloaded, without affecting the placement of new materials or the hot pressing process.

[0022] 3. Through the cooperation of the reset assembly and the fourth return spring, the connecting plate can effectively reset the pusher during the downward movement, ensuring stable operation of the next unloading.

[0023] 4. The material receiving assembly can effectively store the unloaded materials in a centralized manner, thereby facilitating unified handling for subsequent processing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0035] like Figure 1-7As shown, a new type of PCB board hot pressing device includes a base 1, a frame 11, a hydraulic cylinder 12, a tension and pressure sensor 13, a connecting plate 14, a heating mechanism 15, an upper mold 16, a control panel 17 and a lower mold 2. The control panel 17 is electrically connected to the outside world. The control panel 17 is electrically connected to the hydraulic cylinder 12, the heating mechanism 15 and the tension and pressure sensor 13. The lower mold 2 is arranged at the upper end of the base 1 and corresponds to the upper mold 16. The lower mold 2 is provided with an assembly cavity 21, and a fixing block 22 is provided in the middle of the assembly cavity 21. A first slide bar 23 is fixedly connected between the fixed block 22 and the front inner wall of the assembly cavity 21. The first slide bar 23 is slidably equipped with a slide plate 24. The first slide bar 23 is provided with a first return spring 25 located between the slide plate 24 and the fixed block 22. A pushing component is provided on the upper side of the slide plate 24. The slide plate 24 is provided with a first stabilizing component. A discharge mechanism is provided on both sides of the slide plate 24. The discharge mechanism includes an extension plate 26 fixedly connected to the slide plate 24 and a movable groove 3 opened on the lower mold 2. The middle position of the lower wall of the movable groove 3 An arc-shaped groove 31 is provided, the lowest point of the arc-shaped groove 31 matches the front wall of the fixed block 22, a pusher is slidably assembled in the movable groove 3, and the pusher includes an assembly block 32. A limit assembly is provided on both sides of the assembly block 32. The assembly block 32 has a cavity 33. The upper and lower ends of the assembly block 32 are provided with a through hole connected to the cavity 33. A mounting block 34 is slidably assembled in the cavity 33. The upper and lower ends of the mounting block 34 are respectively provided with a lock tongue 35 and a roller 36 extending out of the cavity 33. The lock tongue 35 is extended away from the extension A slope 351 is provided on one side of the plate 26, the mounting block 34 is provided with a telescopic component matching the lock tongue 35, the mounting block 34 is provided with a second stabilizing component matching the cavity 33, the front side of the assembly block 32 is provided with a first cable 4, the other end of the first cable 4 is connected to a reset component, the rear side of the assembly block 32 is fixedly connected to a second cable 41 extending out of the movable groove 3, two connecting strips 42 are provided on the rear side of the connecting plate 14, the two connecting strips 42 are respectively fixedly connected to the two second cables 41, and a material connecting component is provided on the rear side of the base 1.

[0036] By adopting the technical solution of the present invention, in the initial state, the output shaft of the hydraulic cylinder 12 is not extended, so that the upper mold 16 and the lower mold 2 are not pressed together, and the pushing component is located on the front side of the upper mold 16, and the pushing member is located on the front side of the extension plate 26; when hot pressing is performed, the workpiece to be processed is placed on the upper side of the lower mold 2, and then the hydraulic cylinder 12 is started through the control panel 17. At this time, the output shaft of the hydraulic cylinder 12 extends to push the connecting plate 14 downward, and then pushes the upper mold 16 downward until it is pressed together with the lower mold 2.

[0037] When the hot pressing process is completed, the output shaft of the hydraulic cylinder 12 is gradually retracted, so that the connecting plate 14 is gradually moved upward, and the two second cables 41 are gradually pulled out of the movable groove 3. When the second cable 41 is gradually pulled out of the movable groove 3, the second cable 41 will drive the pushing member to move together; when the pushing member moves, the roller 36 located at the lower side of the mounting block 34 rolls accordingly, and the locking tongue 35 located on the upper side of the mounting block 34 is against the extension plate 26, and then as the connecting plate 14 moves, the extension plate 26 is gradually pushed to move, thereby causing the slide plate 24 to gradually move, and then the pushing assembly connected to the slide plate 24 is gradually moved to the rear side of the lower mold 2, so that the material on the upper side of the lower mold 2 is gradually pushed to the rear side of the lower mold 2 until it is subjected to gravity and falls into the material receiving assembly. When the pushing member continues to move until it gradually moves to the arc groove 31, due to the second stabilizing assembly When the cam 35 is in the downward position, the locking tongue 35 of the cam 35 is gradually retracted into the cavity 33 of the assembly block 32, thereby causing the locking tongue 35 to gradually disengage from the extension plate 26. When the cam 35 is in the downward position, the locking tongue 35 is completely disengaged from the extension plate 26. At this time, due to the rebound of the first return spring 25, the slide plate 24 is pushed to move back to the front side of the lower mold 2, thereby causing the pushing assembly to be reset to the front side of the lower mold 2. Since the lowest point of the arc groove 31 matches the front wall surface of the fixed block 22, it can prevent the slide plate 24 from being blocked by the fixed block 22 when the locking tongue 35 has not yet completely disengaged from the extension plate 26, causing conflict between the components. The limit assembly can make the movement of the pusher more stable.

[0038] When the pushing assembly is reset, the connecting plate 14 will continue to move up until it is reset, and the pushing member will continue to move to the rear side of the lower mold 2 until the connecting plate 14 stops moving. When the upper mold 16 stops moving and the mold is fully opened, the new material to be processed can be placed on the upper side of the lower mold 2 for a new hot pressing process. Since the pushing assembly has been reset in advance during the process of the upper mold 16 rising and resetting, it will not affect the placement of the new material. When the upper mold 16 is pressed down again, the connecting plate 14 will move down again. Since the first cable 4 is connected to the reset assembly, and the first cable 4 is connected to the pushing member, and the pushing member is at the rear side of the lower mold 2 at this time, when the connecting plate 14 moves down, the reset assembly will pull The first cable 4 is moved toward the front side of the lower mold, thereby causing the pushing member to gradually move toward the front side of the lower mold 2, so that the second cable 41 is also pulled into the movable groove 3. When the pushing member gradually moves to the reset extension plate 26, the locking tongue 35 of the pushing member will be squeezed with the extension plate 26, and because the roller 36 is in contact with the lower wall of the movable groove 3 and cannot drop, the locking tongue 35 is pushed back into the cavity 33 of the assembly block 32 through the guidance of the inclined surface 351. At this time, the telescopic component is compressed. When the pushing member continues to move until it passes the extension plate 26, the telescopic component rebounds and pushes out the locking tongue 35, thereby resetting the pushing member. In this way, when the mold is opened again, new material can be pushed into the receiving component again.

[0039] The present invention uses a unloading mechanism to quickly unload materials during the mold opening process without manual operation, avoiding manual operation that is prone to scratching, pressing, and scalding, thereby improving the safety of hot pressing processing. At the same time, it can automatically reset after unloading without affecting the loading of new materials, thereby greatly improving production efficiency and reducing the unloading operations required for hot pressing processing.

[0040] The telescopic assembly preferably includes a stepped hole 5 provided in the mounting block 34. A second return spring 51 is fixedly connected to the bottom wall of the stepped hole 5. The other end of the second return spring 51 is fixedly connected to a stop block 52 that matches the stepped hole 5. The upper end of the stop block 52 is fixedly connected to the lock tongue 35. With this structure, when the lock tongue 35 is squeezed, the inclined surface 351 guides the lock tongue 35 downward, thereby causing the stop block 52 to move toward the bottom of the stepped hole 5. At this time, the second return spring 51 is compressed. When the lock tongue 35 passes over the extension plate 26, the second return spring 51 rebounds and pushes the stop block 52 out, thereby returning the lock tongue 35 to its original position. The stop block 52 prevents the lock tongue 35 from being disconnected from the stepped hole 5. In fact, other structures can also be considered according to specific circumstances to more effectively control the extension and retraction of the lock tongue 35.

[0041] The second stabilizing assembly preferably includes two limit sliders 6 located on the left and right sides of the mounting block 34 and fixedly connected to the mounting block 34. Two limit sliders 61 are provided between the upper and lower inner walls of the cavity 33, each of which matches the two limit sliders 6. The limit sliders 6 are slidably assembled with the limit sliders 61. Each limit slider 61 is sleeved with a third return spring 62 located between the upper inner wall of the cavity 33 and the upper end of the limit sliders 6. With this structure, when the pusher moves to the arcuate groove 31, the roller 36 follows the trajectory of the arcuate groove 31. Due to the action of the third return spring 62, the limit slider 6 gradually moves downward with the movement of the pusher, thereby ensuring that the roller 36 always adheres to the arcuate groove 31. The limit sliders 61 ensure smooth movement of the limit sliders 6, while the limit sliders 6 prevent the mounting block 34 from becoming disconnected from the cavity 33. In practice, other structures may be considered to ensure more stable extension and retraction of the mounting block 34, depending on the specific situation.

[0042] The push assembly preferably includes a push groove 241 and a push plate 242. The movable groove 3 is located on the upper side of the lower mold 2 and connected to the assembly cavity 21. The lower side of the push plate 242 passes through the push groove 241 and connects to the upper side of the slide 24. This structure allows the push plate 242 to move within the push groove 241 along with the movement of the slide 24, thereby gradually pushing the material into the receiving assembly. In practice, other structures can also be considered to more conveniently push the material, depending on the specific situation.

[0043] Preferably, the second cable 41 is sheathed with a fourth return spring 411 positioned between the movable slot 3 and the assembly block 32, and a guide pulley matching the second cable 41 is provided on the rear side of the lower die 2. With this structure, the fourth return spring 411 can exert a more effective thrust when the pusher is reset and moves toward the front of the lower die 2, preventing the locking tongue 35 from being unable to pass over the extension plate 26 due to insufficient reset force. The guide pulley can also guide the second cable 41, ensuring the stability of its movement. In practice, other structures can also be considered depending on the specific situation to increase the reset thrust of the pusher and improve the stability of the movement of the second cable 41.

[0044] The preferred reset assembly includes two protrusions 7 fixedly connected to the inner wall of the movable groove 3. A winding wheel 71 is rotatably mounted between the two protrusions 7. The first cable 4 is connected to the winding wheel 71, and the winding wheel 71 is provided with a coil spring 72. With such a structure, the first cable 4 is connected to the winding wheel 71. When the pusher moves toward the rear side of the lower mold 2, the winding wheel 71 is rotated by the tension and releases the first cable 4. At this time, the coil spring 72 is wound. When the connecting plate 14 moves downward, the tension on the rear side of the lower mold 2 disappears. At this time, the coil spring 72 rewinds and retracts the first cable 4, thereby pulling the pusher to reset. In fact, other structures can also be considered according to specific circumstances to make it easier to reset the pusher.

[0045] The first stabilizing assembly preferably includes two first stabilizing rods 231 arranged parallel to the first slide bar 23 and located on the left and right sides of the first slide bar 23, respectively. Both first stabilizing rods 231 are located between the fixed block 22 and the front inner wall of the assembly cavity 21, and are slidably assembled with the slide plate 24. This structure can further stabilize the movement of the slide plate 24. In fact, other structures can also be considered to further stabilize the movement of the slide plate 24 depending on the specific situation.

[0046] The preferred limiting assembly includes a T-shaped slot 8 formed in the sidewall of the movable slot 3, and the assembly block 32 is fixedly connected to a T-shaped slider 81 that matches the T-shaped slot 8. This structure can further stabilize the movement of the assembly block 32. In fact, other structures can also be considered to further stabilize the movement of the assembly block 32 depending on the specific situation.

[0047] The material receiving assembly preferably includes a guide ramp 9 located behind the lower die 2, and a receiving frame 91 that matches the guide ramp 9 on the rear side of the base 1. With this structure, the guide ramp 9 guides the material into the receiving frame 91, which effectively stores the hot-pressed material for subsequent processing. In practice, other structures may be considered to further facilitate material unloading and storage, depending on the specific situation.

Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention.
