Description

Technical Field

[0001] The utility model belongs to the technical field of circuit board processing, and particularly relates to a push-type circuit board splitting device. Background Art

[0002] Circuit boards are the carriers for electrical connections of electronic components. When processing circuit boards, multiple groups of circuit boards will be processed on the same substrate. After processing is completed, the electronic components will be separated by a board separator. The existing technology generally fixes multiple blades at intervals on a rotating shaft, which is inconvenient to adjust the spacing between the blades according to different circuit boards.

[0003] The Chinese patent with announcement number CN117412503B discloses a device and method for cutting and slicing circuit boards. The scheme includes a workbench and a positioning and pushing device. A drive shaft is rotatably arranged above the workbench, and a cutter disc is connected to the outer outer surface of the drive shaft. A transmission loading and unloading mechanism is arranged inside the drive shaft. The transmission loading and unloading mechanism includes an operating rod, and a plurality of positioning blocks are equidistantly arranged on the surface of the operating rod. A card slot that cooperates with the positioning block is opened inside the cutter disc. After the above scheme moves the cutter disc to the appropriate position, the positioning block is clamped in the card slot to fix the cutter disc, thereby achieving the purpose of adjusting the position of the cutter disc.

[0004] When the above solution is in use, since multiple positioning blocks are fixed on the operating rod at equal distances, the cutter disc can only be connected to the operating rod at multiple fixed positions. The adjustment range of the distance between two adjacent cutter discs is small, and the applicable scenarios are relatively limited. Utility Model Content

[0005] The utility model aims to provide a push-type circuit board splitting device to solve the problem that the above-mentioned solution has limited applicable scenarios.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] 7. The swiftly and minutely adjusting device for a wood-planer working table as claimed in claim 1, wherein said linking rod and said adjusting base are pivotally connected to each other with a bolt, and said bolt has a round shank to contact with said linking rod. said linking rod having a round shank and a bolt of said bolt. said linking rod having a round shank and a bolt of said bolt.

[0008] The principle and effect of this technical solution:

[0009] Multiple cutting components are hung on the slide at intervals, and then a partition component is placed between two adjacent cutting components. The distance between the first two cutting components is adjusted by the limit component, and the push rod is moved to abut against the first slider of each partition component. The push rod is continued to be moved, and each first slider moves toward the second slider. The two connecting rods rotate in the direction away from each other, thereby pushing the two second sliders of each partition component away from each other until each second slider abuts against the adjacent cutting component, so that the feeding component transfers the circuit board to the bottom of the cutting component, so that multiple cutting components can simultaneously split the circuit board.

[0010] Through the above setting, the sliding push rod is used to change the distance between the two second sliders in each partition assembly, thereby adjusting the distance between two adjacent cutting assemblies, expanding the adjustment range of the distance between the two adjacent cutting assemblies, and broadening the applicable scenarios of the device.

[0011] In the present invention, the cutting assembly includes a bracket and a blade. The bottom of the bracket is slidably inserted into the through slot, and the top of the bracket is slidably hung on the through slot. The blade is fixedly provided with a connecting shaft along its axial direction. The connecting shaft is rotatably connected to the bottom of the bracket. A motor is fixedly provided on the side wall of the workbench. The output end of the motor is transmission-connected to a rotating shaft. The rotating shaft can rotate relative to the mounting frame, and the rotating shaft slides through each connecting shaft in turn and can drive each connecting shaft to rotate.

[0012] In the present invention, the limiting mechanism includes a pressure rod fixedly arranged above the through slot along the length direction of the through slot, the top of each bracket and the top of each second slider are respectively slidably abutted against the bottom of the pressure rod, a cavity is provided in the pressure rod, a first bidirectional screw is rotatably provided in the cavity, the bottom wall of the cavity is provided with an opening along its length direction, two limiting blocks are slidably embedded in the cavity, the two limiting blocks are respectively fitted on the forward and reverse thread sections of the first bidirectional screw, and the bottom of the limiting block is slidably passed through the opening.

[0014] In the present invention, a through discharge port is provided on the top of the workbench below the mounting frame, and the lower edge of the blade is lower than the upper edge of the discharge port.

[0015] In the present invention, mounting plates are fixedly provided on the top of the mounting frame at both sides of the through slot, and both ends of the pressure rod are fixedly connected to the two mounting plates by bolts respectively.

[0016] The principle and effect of this technical solution:

[0017] Before performing the cutting work, first remove the pressure rod from the mounting plate, arrange multiple brackets at intervals in the through slot, and hang the top of the bracket on the through slot, then set a separation component between two adjacent cutting components, and then rotate the first bidirectional screw. Due to the rotation of the cavity limiting limit block, the two limit blocks approach each other as the first bidirectional screw rotates until the spacing between the two limit blocks reaches a predetermined value, and then move the push rod by rotating the first screw to push the first slider close to the through slot until each second slider is respectively pressed against the adjacent brackets. At this time, the bottom of each bracket is respectively connected to the corresponding blade, and the rotating shaft is passed through each connecting shaft in turn, so that one end of the rotating shaft is connected to the motor transmission, and the motor is started to drive multiple blades to rotate through the rotating shaft. Finally, the feeding assembly is used to push the circuit board through the blade, so that each blade cuts the circuit board, and the formed circuit board is turned out through the discharge port.

[0018] Through the above-mentioned setting, by rotating the first bidirectional screw, the two limit blocks are pressed against the first and tail cutting components to limit the cutting components. Before installing the cutting component and the separating component, the pressure rod is removed from the mounting plate, which can facilitate the staff to install the cutting component and the splitting component and improve the practicality of the device.

[0020] The principle and effect of this technical solution:

[0021] Place the circuit board to be split between the two clamping blocks, rotate the second bidirectional screw, and the two clamping blocks move closer to each other because the movable groove limits the rotation of the clamping blocks, until they are respectively pressed against the circuit board. At this time, rotate the second screw, and the sliding groove limits the rotation of the third slider, so that the third slider pushes the moving seat close to the mounting frame, and at the same time, the two clamping blocks clamp the circuit board and move it to the bottom of the cutting assembly, thereby completing the circuit board splitting work.

[0022] Through the above arrangement, the purpose of enabling the feeding assembly to transfer the circuit board to the bottom of the cutting assembly can be achieved.

[0032] As attached Figure 1-5 As shown, the utility model discloses a push-type circuit board splitting device, including a workbench 10, a cutting assembly 20, a spacing adjustment mechanism, a limiting mechanism and a feeding assembly.

[0034] In this embodiment, the limiting mechanism includes a pressure rod 50 fixedly arranged above the through groove 111 along the length direction of the through groove 111, and the top of each bracket 21 and the top of each second slider 322 are respectively slidably abutted against the bottom of the pressure rod 50. A cavity is provided in the pressure rod 50, and a first bidirectional screw 51 is rotatably provided in the cavity. The bottom wall of the cavity is provided with an opening 52 along its length direction, and two limit blocks 53 are slidably embedded in the cavity. The two limit blocks 53 are respectively fitted on the positive and negative thread sections of the first bidirectional screw 51, and the bottom of the limit block 53 is slidably passed through the opening 52, and the limit block 53 can abut against the side wall of the bracket 21.

[0035] In this embodiment, a connecting block 14 is fixedly provided on the top of the mounting frame 11 away from the through slot 111 . A first screw rod 141 is threaded through the connecting block 14 . One end of the first screw rod 141 is rotatably connected to the push rod 31 .

[0036] In this embodiment, a through discharge port 15 is provided on the top of the workbench 10 below the mounting frame 11 , and the lower edge of the blade 22 is lower than the upper edge of the discharge port 15 .

[0037] In this embodiment, mounting plates 16 are fixedly provided on both sides of the through slot 111 at the top of the mounting frame 11 , and both ends of the pressure rod 50 are fixedly connected to the two mounting plates 16 by bolts.

[0038] The second screw 171 is rotatably provided in the slide groove 17, and the feeding assembly includes a movable seat 41 slidably provided on the top of the workbench 10, and a third slider 42 is fixedly provided on the side of the movable seat 41 away from the mounting frame 11. The bottom of the third slider 42 is slidably embedded in the slide groove 17 and is cooperated with the second screw 171. A movable groove 411 is recessed on the side of the movable seat 41 close to the discharge port 15, and a second bidirectional screw 412 is rotatably provided in the movable groove 411, and two clamping blocks 413 are slidably embedded in the movable groove 411. The two clamping blocks 413 are respectively cooperated with the positive and negative thread sections of the second bidirectional screw 412. One end of the clamping block 413 protrudes from the movable groove 411 and slides against the top of the workbench 10.

[0039] In this embodiment, the bottom of the push rod 31 close to the first sliding block 321 has a slot, and the bottom of the first sliding block 321 close to the push rod 31 has a protrusion that is slidably engaged in the slot.

[0040] The first screw 141 , the second screw 171 , the first bidirectional screw 51 , and the second bidirectional screw 412 can all be driven manually or by a motor.

[0041] The specific implementation process is as follows:

[0042] A plurality of cutting assemblies 20 are hung on the slide groove 17 at intervals, and then a partition assembly 32 is placed between two adjacent cutting assemblies 20. The spacing between the first two cutting assemblies 20 is adjusted by the limit assembly, and the push rod 31 is moved to make it abut against the first slider 321 of each partition assembly 32. The push rod 31 is continued to be moved, and each first slider 321 moves toward the second slider 322. The two connecting rods 323 rotate in a direction away from each other, thereby pushing the two second sliders 322 of each partition assembly 32 away from each other until each second slider 322 is pressed against the adjacent cutting assemblies 20, so that the feeding assembly transfers the circuit board to the bottom of the cutting assembly 20, so that multiple cutting assemblies 20 can simultaneously cut the circuit board.

[0043] Before the splitting work, first remove the pressure rod 50 from the mounting plate 16, and insert multiple brackets 21 into the through slot 111 at intervals, and hang the top of the bracket 21 on the through slot 111. Then set a separation component 32 between two adjacent cutting components 20, and then rotate the first bidirectional screw 51. Due to the rotation of the cavity limiting limit block 53, the two limit blocks 53 move closer to each other as the first bidirectional screw 51 rotates until the distance between the two limit blocks 53 reaches a predetermined value. Then, by rotating the first screw 141, the push rod 31 is moved, so that the push rod 31 pushes the first slider 321 close to the through slot 111 until each second slider 322 is pressed against the adjacent bracket 21. At this time, the bottom of each bracket 21 is rotatably connected to the corresponding blade 22, and the rotating shaft 13 passes through each connecting shaft 221 in sequence, so that one end of the rotating shaft 13 is connected to the motor 12 for transmission. The motor 12 is started to drive the multiple blades 22 to rotate through the rotating shaft 13. Finally, the feeding assembly is used to push the circuit board through the blade 22, so that each blade 22 cuts the circuit board, and the formed circuit board is rotated out through the discharge port 15.

[0044] Place the circuit board to be split between the two clamping blocks 413 and rotate the second bidirectional screw 412. Since the movable groove 411 limits the rotation of the clamping block 413, the two clamping blocks 413 move closer to each other until they are respectively pressed against the circuit board. At this time, rotate the second screw 171. Since the sliding groove 17 limits the rotation of the third slider 42, the third slider 42 pushes the movable base 41 close to the mounting frame 11. At the same time, the two clamping blocks 413 clamp the circuit board and move it to the bottom of the cutting assembly 20, thereby completing the circuit board splitting work.

[0045] In this patented solution, three cutting assemblies are provided. In actual application, the number of cutting assemblies can be increased (for example, to four or more) based on the number of small circuit boards that need to be divided from a large circuit board to meet the production needs of circuit board segmentation. In addition, in this patented solution, the cutting assemblies are slidably mounted on the through slots, and the number of separating assemblies can also be easily increased, thereby making it relatively easy to adjust the number of cutting assemblies.

[0046] The above description is merely an embodiment of the present invention, and the commonly known specific technical solutions or features in the solution are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be considered as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
