Description

Technical Field

[0001] The invention belongs to the technical field of integrated circuits, and in particular relates to a PCB board component pressing device for an integrated circuit carrier. Background Art

[0002] An integrated circuit is a miniature electronic device that connects the required components together through a printed circuit board (PCB). During the production process of PCBs, some PCBs use a multi-layer lamination process. At this time, lamination equipment is used. The lamination equipment can press the multiple layers of PCBs together to form a single multi-layer PCB.

[0003] A Chinese patent with the existing announcement number CN114567977B discloses a PCB board pressing device, which includes a frame, and an upper pressing mechanism, an upper mold assembly, a lower mold assembly, and a typesetting mechanism are arranged above the frame. It solves the problems of low automation and cumbersome operation of PCB board pressing devices in the existing technology.

[0004] During use of the above-mentioned technical solution, a single-layer PCB board needs to be placed into the placement cavity. However, during the placement process, a push-and-slide method is adopted. During this process, it is easy for the sliding distance to be insufficient due to friction. At this time, the PCB board is in an offset state inside the placement cavity. If it is directly pressed together, the pressing positions of the two layers of PCB boards will not be aligned, resulting in damage to the PCB boards. If manual adjustment is performed, it will take a certain amount of time, affecting the efficiency of pressing.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0033] like Figures 1 to 2 As shown, an embodiment of the present invention provides a PCB component pressing device for an integrated circuit carrier, comprising a workbench 1, a pressing assembly 22 mounted on the top of the workbench 1, a pressing platform 2 mounted on one end of the pressing assembly 22, a pressing box 21 disposed below the pressing platform 2, the bottom end of the pressing box 21 being fixedly connected to the top of the workbench 1, feeding structures disposed on both sides of the pressing box 21, capable of conveying PCBs to the top of the pressing box 21 and unloading the materials, and a guide slope 215 disposed on the inner side of the top of the pressing box 21 for guiding the PCBs when they are fed into the pressing box 21;

[0034] PCB boards are needed when processing integrated circuits. PCB boards will be of different types depending on the usage. Multi-layer PCB boards will be used when complex circuits are needed. When processing multi-layer PCB boards, multiple single-layer PCB boards need to be pressed together. During processing, the PCB boards are loaded into the feeding structure, and then the feeding structure is started. At this time, the feeding structure on the left first puts the first PCB board into the pressing box 21, and then the feeding structure on the left is reset, and then the feeding structure on the right is started to feed the second PCB board into the pressing box 21. When the feeding structure transports the PCB board, it will move the PCB board to the top of the pressing box 21 and then unload it. Then, the PCB board can be introduced into the pressing box 21 through the guide slope 215. Since the PCB board is lowered from the top of the pressing box 21, the PCB board and the pressing box can be 21 will not have a large error, and the PCB board can be guided into the interior of the pressing box 21 through the guide slope 215. During this process, the PCB board can enter the interior of the pressing box 21 more accurately, and damage caused by inaccurate prevention during the pressing process can be avoided. After the two PCB boards are placed in the pressing box 21, the cylinder of the pressing assembly 22 is started to push the connecting block of the pressing table 2 downward to drive the pressing table 2 to move downward, and the pressing table 2 moves into the interior of the pressing box 21. At this time, the pressing table 2 compacts the two PCB boards inside the pressing box 21 and starts the heating component inside the pressing table 2 to heat. At this time, the two PCB boards can be pressed together in the pressing box 21. After the pressing is completed, the pressing assembly 22 drives the pressing table 2 to rise. At this time, the pressed PCB board can be taken out from the interior of the pressing box 21. The above method can be repeated to press multiple PCB boards.

[0035] like Figures 1 to 5 The cam 321 is fixed to the top of the workbench 1, and the bottom PCB board is placed in the cam 322 on the left side, and the top PCB board is placed in the cam 322 on the right side. A pushing plate 32 is slidably connected to the interior of the cam 3, and two groups of second slides 323 are fixed on both sides of the pushing plate 32. A slide groove is provided on both sides of the interior of the cam 3. The second slide 323 is slidably connected to the interior of the slide groove of the cam 3. A second spring 322 is fixed to the bottom end of the second slide 323. The bottom end of the second spring 322 is fixedly connected to the inner wall of the slide groove. A guide rod 321 is fixed to the interior of the slide groove. The guide rod 321 runs through the interior of the second slide 323. The second spring 322 is sleeved on the outside of the guide rod 321. A material picking assembly is provided at the top of the cam 3.

[0036] When the PCB board is put into the receiving groove 3 on both sides in a unified direction, the directions of the PCB boards on both sides are the corresponding directions during pressing. When the PCB board enters the receiving groove 3, the pushing plate 32 is pressed downward. At this time, the PCB board is put into the receiving groove 3 from the top of the receiving groove 3 close to the opening on one side of the pressing box 21. When the PCB board is loaded into the receiving groove 3, the pushing plate 32 will be squeezed downward, and the pushing plate 32 drives the second slide plate 323 to squeeze the second spring 322 downward. During use, the material taking component will push the topmost The PCB board is taken out, and a gap will appear above the pushing plate 32 each time the PCB board is taken out. At this time, the elastic force of the second spring 322 will push the second slide plate 323 to move upward, and the second slide plate 323 drives the pushing plate 32 to push the PCB board upward to fill the gap, thereby realizing automatic material replenishment. After the material-taking structure takes out the PCB board, it will move above the pressing box 21 and place the material just above the pressing box 21. Then the material-taking structure will return to the top of the receiving slot 3. In this way, the pushing plate 32 can cooperate with the material-taking structure to place the PCB board into the interior of the pressing box 21.

[0037] like Figures 1 to 7 As shown, the material taking assembly includes an electric telescopic rod 31 installed on one side of the workbench 1, and a movable plate 33 is provided on the side of the electric telescopic rod 31 close to the storage slot 3. Clamps 36 are provided on both sides of the bottom end of the movable plate 33, and driving assemblies are provided on both sides of the top end of the clamping plate 36.

[0038] During the material taking process, the electric telescopic rod 31 is started to drive the movable plate 33 to move to the middle of the top of the storage slot 3. At this time, the driving component drives the two clamping plates 36 to clamp the PCB board. After clamping, the electric telescopic rod 31 is started to push the movable plate 33 to move toward the pressing box 21. The movable plate 33 drives the PCB board to move above the pressing box 21 through the clamping plates 36. When the PCB board moves to the top of the pressing box 21, the driving component drives the two clamping plates 36 to move to both sides to make the PCB board fall off from the bottom of the movable plate 33. At this time, the PCB board can enter the interior of the pressing box 21.

[0039] like Figures 1 to 9 As shown, the driving assembly includes push racks 365 slidably connected to both sides of the interior of the movable plate 33. The bottom ends of the two push racks 365 are fixedly connected to the clamping plate 36. A third spring 364 is fixed to one side of the push rack 365 close to the clamping plate 36. The third spring 364 is fixedly connected to the movable plate 33. A pushing assembly is provided between the two push racks 365.

[0040] When the two clamping plates 36 clamp and release the PCB board, the pushing component will push the two pushing frames 365 to both sides. During the pushing process, the pushing frames 365 will drive the two clamping plates 36 to separate from the PCB board. When clamping, the pushing component will reset. At this time, the third spring 364 will push the pushing frame 365 to reset. The pushing frame 365 drives the clamping plates 36 to reset and the PCB board can be clamped.

[0041] like Figures 1 to 9 As shown, a flip plate 361 is provided at the bottom end of the splint 36, and an elastic piece 362 is fixed to the side of the flip plate 361 close to the third spring 364. The bottom end of the elastic piece 362 is fixedly connected to the flip plate 361, and a slope is provided on the side of the splint 36 close to the third spring 364.

[0042] During the clamping process, the elastic sheet 362 can tighten the space between the clamping plate 36 and the flip plate 361, so that the flip plate 361 can clamp the PCB board.

[0043] like Figures 1 to 10 When the cam 331 is unlocked, the locking cam 332 is unlocked and the locking cam 333 is unlocked, so that the cam 332 can be unlocked.

[0044] When the cam 331 is in the unlock position, the first locking plate 331 is pushed back to the unlock position, and the locking plate 331 is unlocked, so that the locking plate 331 is unlocked. Figure 5 At this time, the first rotating block 331 loses its thrust, and the coil spring 333 drives the connecting rod 332 to reset. Then, the docking hook 367 loses its tension, and the elastic force of the third spring 364 drives the push frame 365 to reset. The push frame 365 pushes the eccentric block of the second rotating block 366 to reset the second rotating block 366. At this time, the docking hook 367 is also driven to reset, and the clamping plate 36 is driven by the push frame 365 to clamp the PCB board.

[0045] After the first rotating block 331 is removed from above the baffle 35, the coil spring 333 will drive the connecting rod 332 to reset. At this time, the connecting rod 332 can pull the card column 335 through the pull rod 334 to slide back into the interior of the docking hook 367, which is convenient for subsequent use.

[0046] like Figures 1 to 3 As shown, a set of limit blocks 214 are fixed on both sides of the pressing box 21, and each set of limit blocks 214 is provided with two, and the top ends of the limit blocks 214 extend to the top of the pressing box 21;

[0047] When the movable plate 33 moves to the top of the pressing box 21, the PCB needs to be put down. At this time, the movable plate 33 drives the first rotating block 331 to pass through the pressing box 21 and continue to move forward for a distance. Then the electric telescopic rod 31 drives the movable plate 33 to move in the opposite direction. At this time, the limit block 214 will contact the first rotating block 331. The first rotating block 331 is driven to pull the docking hook 367 to rotate, so that the clamping plate 36 can put down the PCB, and automatic material unloading can be realized. During the unloading process, the electric telescopic rod 31 pauses to provide time for unloading.

[0048] like Figures 1 to 5 As shown, a second push plate 312 is fixed to the top of the movable plate 33 near the electric telescopic rod 31, and sliding rods 313 are fixed on both sides of the second push plate 312. A support plate 34 is fixed to both sides of the top of the storage slot 3. A first slide 341 is provided on the side of the support plate 34 near the sliding rod 313. A second slide 342 is provided on the side of the first slide 341 away from the sliding rod 313. A third slide 343 is provided on the side of the second slide 342 away from the first slide 341. The sliding rod 313 is slidably connected to the inside of the first slide 341.

[0049] When the electric telescopic rod 31 pushes the moving plate 33, the electric telescopic rod 31 will push the second push plate 312 to move. At this time, the second push plate 312 slides inside the first slide 341 through the sliding rod 313. At this time, the moving plate 33 moves horizontally. When the sliding rod 313 moves to the inside of the second slide 342, the moving plate 33 will be driven downward. At this time, the moving plate 33 can drive the PCB board closer to the top of the pressing box 21. When the moving plate 33 moves to the top of the pressing box 21, it needs to move a distance to discharge the material. At this time, the sliding rod 313 moves inside the third slide 343, and then the electric telescopic rod 31 pulls the moving plate 33 to reset, so that the moving plate 33 can return to its original path.

[0050] like Figures 1 to 5 As shown, a guide groove is provided inside the second push plate 312, and a first slide plate 311 is fixed to one end of the electric telescopic rod 31 close to the second push plate 312. The first slide plate 311 is slidably connected to the guide groove of the second push plate 312;

[0051] When the movable plate 33 moves, it will move downward under the guidance of the second slide 342. At this time, the first slide 311 slides inside the guide groove of the second push plate 312, and the connection state between the first slide 311 and the second push plate 312 can be adaptively adjusted, which can make the movement of the movable plate 33 more convenient.

[0052] like Figures 1 to 4 As shown, the interior of the pressing box 21 is slidably connected to a lifting plate 211, and a lifting column 212 is passed through the bottom end of the pressing box 21. The top of the lifting column 212 is fixedly connected to the lifting plate 211, and a first spring 213 is fixed to the outside of the lifting column 212. The top of the first spring 213 is fixedly connected to the pressing box 21. A rocker plate 232 is rotatably connected to the side of the left storage slot 3 below the pressing box 21. One side of the rocker plate 232 extends to the bottom of the lifting column 212. A rotating rod 23 is fixed to one end of the rocker plate 232 rotation axis close to the pressing assembly 22. A first push plate 231 is fixed to the end of the rotating rod 23 away from the rocker plate 232. The sliding rod 313 close to the side of the first push plate 231 extends from the first slide 341, and the first push plate 231 can be tightly attached to the sliding rod 313;

[0053] When the PCB board is pressed, the lifting plate 211 is set to the position where the PCB board is pressed.
