Description

Technical Field

[0001] The present invention relates to the technical field of cutting, and particularly relates to a combined device for pressing and cutting PCB boards. Background Art

[0002] The Chinese name of PCB is printed circuit board, also known as printed wiring board. It is an important electronic component, a support for electronic components, and a carrier for the electrical connection of electronic components. In the manufacturing process of PCB boards, multiple processing steps are involved, including the cutting process of PCB boards. The Chinese patent with the publication number CN212421544U discloses a cutting device for PCB boards used in electronic design, which relates to a cutting device including a base. A box body is fixedly connected above the base. A first rotating shaft is rotatably connected to the upper middle part of the left wall of the box body. A longitudinal control disk is fixedly connected to the left end of the first rotating shaft, and a driving bevel gear is fixedly connected to the right end of the first rotating shaft. A first rotating shaft support plate is fixedly connected to the middle part of the inner side of the left wall of the box body. A longitudinal shaft is rotatably connected to the first rotating shaft support plate. A first driven bevel gear is fixedly connected to the top end of the longitudinal shaft. The driving bevel gear meshes with the first driven bevel gear. A second driven bevel gear is fixedly connected to the bottom end of the longitudinal shaft. This cutting device directly places the PCB board on the cutting table for cutting. Since there is no measure to position the PCB board on the cutting table, the PCB board is prone to shaking during the cutting process of the PCB board, thereby affecting the cutting effect.

[0003] To solve the above problems, the Chinese patent with the publication number CN222609743U discloses a cutting device for PCB boards used in electronic design, including a base. A box body is fixedly connected above the base. A first rotating shaft is rotatably connected to the upper middle part of the left wall of the box body. A longitudinal control disk is fixedly connected to the left end of the first rotating shaft, and a driving bevel gear is fixedly connected to the right end of the first rotating shaft. A first rotating shaft support plate is fixedly connected to the middle part of the inner side of the left wall of the box body. A longitudinal shaft is rotatably connected to the first rotating shaft support plate. A first driven bevel gear is fixedly connected to the top end of the longitudinal shaft. The driving bevel gear meshes with the first driven bevel gear. A second driven bevel gear is fixedly connected to the bottom end of the longitudinal shaft. This cutting device can first position the PCB board and then perform the cutting process, thereby avoiding the shaking of the PCB board during the cutting process of the PCB board and ensuring the cutting effect.

[0004] The following problems exist during the actual use of the above improved cutting device: After the PCB board is placed in the processing table, the two fixing plates are moved closer to clamp and position the PCB board. However, if the inside of the processing table is filled with PCB boards, after the cutting process of the PCB board is completed, it is inconvenient for the staff to take out the cut PCB board, and the operation is very inconvenient. Summary of the Invention

[0005] The present invention aims to provide a combined device for pressing and cutting PCB boards, so as to solve the problem that it is not convenient to take out the cut PCB board after the existing cutting device finishes cutting the PCB board.

[0006] To achieve the above object, the present invention adopts the following technical solution: A combined device for pressing and cutting PCB boards includes a base. There is a groove on the base. A vertical groove and horizontal grooves on both sides of the vertical groove are provided at the bottom of the groove. A support table is slidably connected in the vertical groove, and a clamping plate is slidably connected in the horizontal groove. A first spring is provided between the clamping plate and the horizontal groove; There is a chamber in the base, and the chamber communicates with the vertical groove; On both sides of the chamber, movable mechanisms are symmetrically provided. The movable mechanism includes a wall groove and an inclined groove opened on the inner wall of the chamber. A wall block is slidably connected in the wall groove. A sliding groove is vertically provided on the wall block. A slider is slidably connected in the sliding groove, and the slider is fixedly connected to the bottom of the support table; The distance between the two inclined grooves gradually decreases from top to bottom. An auxiliary block is slidably connected in the inclined groove, and the auxiliary block is fixedly connected to the slider; It also includes an adjusting mechanism for adjusting the distance between the two wall blocks, a driving mechanism for adjusting the distance between the two clamping plates, and a cutting mechanism for cutting the PCB board.

[0007] The principle and advantages of this solution are:

[0008] 1. In this solution, the adjusting mechanism makes the two wall blocks move closer horizontally. During the horizontal movement of the wall blocks, the wall blocks drive the sliders to move synchronously. The sliders will also move downward along the path of the inclined groove through the auxiliary blocks. The sliders drive the support table to move downward, and then the PCB board descends into the groove, so that the PCB board can be cut and processed in the groove, and the redundant materials cut from the PCB board are collected centrally by using the groove.

[0009] 2. In this solution, the driving mechanism makes the two clamping plates move closer horizontally, so that the two clamping plates respectively abut against both sides of the PCB board, thereby realizing the clamping and positioning of the PCB board, so that the cutting mechanism can cut the PCB board.

[0010] 3. After the PCB board is cut and processed in this solution, the adjusting mechanism makes the two wall blocks move away horizontally. During the horizontal movement of the wall blocks, the wall blocks drive the sliders to move synchronously. The sliders will also move upward along the path of the inclined groove through the auxiliary blocks. The sliders drive the support table to move upward, and then the cut PCB board can be pushed out of the groove upward, while the redundant part cut from the PCB board remains in the groove, so that it is convenient for the staff to directly take out the cut PCB board.

[0011] Further, the adjusting mechanism includes a rotating shaft rotatably connected to the chamber, first cylindrical cams at both ends of the rotating shaft, and a stopping part for stopping the rotating shaft. The first cylindrical cams are coaxially connected to the rotating shaft. A first curve groove is provided on the first cylindrical cam. An adjusting block is slidably connected to the first curve groove, and the end of the adjusting block away from the curve groove is fixedly connected to the wall block.

[0012] With the above settings, the rotation of the rotating shaft is driven, the rotating shaft drives the two first cylindrical cams to rotate synchronously, the first cylindrical cam drives the adjusting block to move horizontally through the first curve groove, so that the two adjusting blocks approach each other; during the horizontal movement of the adjusting block, the adjusting block drives the wall block to move synchronously, so that the two wall blocks approach each other; during the horizontal movement of the wall block, the wall block drives the slider to move synchronously, and the slider will also move downward along the path of the inclined groove through the auxiliary block, and the slider drives the support platform to move downward, and then the PCB board descends into the groove.

[0013] After the cutting of the PCB board is completed, the rotating shaft is driven to rotate in the reverse direction, the rotating shaft drives the two first cylindrical cams to rotate in the reverse direction, the first cylindrical cam drives the adjusting block to move horizontally through the first curve groove, so that the two adjusting blocks move away from each other; during the horizontal movement of the adjusting block, the adjusting block drives the wall block to move synchronously, so that the two wall blocks move away from each other; during the horizontal movement of the wall block, the wall block drives the slider to move synchronously, and the slider will also move upward along the path of the inclined groove through the auxiliary block, and the slider drives the support platform to move upward, and then the cut PCB board can be pushed out of the groove upward.

[0014] Furthermore, the driving mechanism includes guiding grooves vertically opened on both sides of the inner wall of the chamber, and a first wedge block fixedly connected to the clamping plate. A second wedge block is vertically slidably connected in the guiding groove. The chamber communicates with the horizontal groove, and the first wedge block abuts against the second wedge block; it also includes a driving part that rotates with the rotating shaft and simultaneously drives the two second wedge blocks to move vertically.

[0015] With the above settings, during the rotation of the rotating shaft, the two second wedge blocks are driven to move upward through the driving part, so that the second wedge block squeezes the first wedge block to drive the clamping plate to move horizontally, so that the two clamping plates approach each other, and the first spring is stretched; the two clamping plates continue to approach each other, so that the two clamping plates respectively abut against both sides of the PCB board, so as to realize the clamping and positioning of the PCB board.

[0016] Furthermore, the driving part includes cam bodies located at both ends of the rotating shaft and side grooves vertically opened on both sides of the inner wall of the chamber. The cam bodies are coaxially connected to the rotating shaft, and the distance between the two cam bodies is greater than the distance between the two first cylindrical cams; a C-shaped frame is slidably connected in the side groove, the C-shaped frame is fixedly connected to the second wedge block, and the cam body abuts against both ends of the C-shaped frame, and the cam body can rotate within the C-shaped frame.

[0017] With the above settings, during the rotation of the rotating shaft, the rotating shaft drives the two cam bodies to rotate, and the cam body drives the second wedge block to move upward through the C-shaped frame.

[0018] Further, a lifting block is vertically slidably connected to the base. A pressing block is provided on the lifting block, and a processing groove is provided on the pressing block. The lifting block extends into the chamber, and a rack is provided on the lifting block. A driving gear is coaxially connected to the rotating shaft.

The diameter of the driving gear is larger than that of the driven gear. The diameters of the driven gear and the linkage gear are the same. The driven gear meshes with the driving gear, and the linkage gear meshes with the rack.

[0019] With the above arrangement, during the rotation of the rotating shaft, the rotating shaft drives the round shaft to rotate through the driving gear and the driven gear. Since the diameter of the driving gear is larger than that of the driven gear, the rotation speed of the round shaft is greater than that of the rotating shaft. The round shaft drives the lifting block to move quickly downward through the linkage gear and the rack. The lifting block drives the pressing block to move downward. When positioning the PCB board, the pressing block abuts against the top of the PCB board, thereby realizing the pressing and positioning of the PCB board and further enhancing the positioning effect of the PCB board.

[0020] Further, side grooves are provided on both sides of the groove. A strip-shaped groove is vertically provided in the side groove. A strip-shaped block is slidably connected in the strip-shaped groove. A second spring is provided between the strip-shaped block and the strip-shaped groove.

The clamping plate is located on the movement track of the deformation of the elastic block. The strip-shaped block is located on the movement track of the pressing block.

[0021] With the above arrangement, during the downward movement of the pressing block, the pressing block also squeezes the strip-shaped block to move downward, so that the distance between the strip-shaped block and the bottom of the side groove decreases, and the second spring is compressed. During the decrease of the distance between the strip-shaped block and the bottom of the side groove, the elastic block deforms, so that the protruding amplitude of the elastic block increases, and the distance between the strip-shaped block and the bottom of the side groove continues to decrease. When positioning the PCB board, the protruding part of the elastic block abuts against the clamping plate, thereby being able to limit and support the clamping plate, and further improving the positioning stability of the clamping plate for the PCB board.

[0022] Further, an auxiliary groove is horizontally provided on the side wall of the strip-shaped groove. The auxiliary groove communicates with the chamber.

An opening is provided on the elastic block, and the support rod can horizontally pass through the opening. An arc-shaped block is provided on the support rod, and the arc-shaped block can abut against the deformed elastic block. Further, an extrusion mechanism for extruding the support rod to move horizontally as the rotating shaft rotates is also included.

[0023] With the above arrangement, during the rotation of the rotating shaft, the support rod is extruded by the extrusion mechanism to move toward the clamping plate, so that the support rod passes through the opening and acts on the clamping plate, that is, the support rod abuts against the clamping plate, thereby being able to limit and support the clamping plate, and further improving the positioning stability of the clamping plate for the PCB board.

[0024] Further, the extrusion mechanism includes a worm coaxially connected to the rotating shaft and a movable shaft rotatably connected to the inner wall of the chamber. A worm gear is coaxially connected to the movable shaft, and the worm gear meshes with the worm. A swing arm for extruding the support rod is provided on the movable shaft.

[0025] With the above arrangement, during the rotation of the movable shaft, the movable shaft drives the swing arm to rotate, so that the swing arm extrudes the support rod to move towards the clamping plate, and the third spring is compressed.

[0026] Further, the stopping part includes an outer groove opened on the side wall of the base, a second cylindrical cam coaxially connected to a single movable shaft, and a fixing plate fixedly connected to the side wall of the base. The outer groove communicates with the chamber. A moving block is slidably connected in the outer groove, and a stopping hole is provided on the moving block. A second curve groove is provided on the second cylindrical cam, and one end of the moving block away from the stopping hole is slidably connected to the second curve groove. A stopping block for passing through the stopping hole is slidably connected vertically on the fixing plate. A fourth spring is provided between the stopping block and the fixing plate. The stopping hole is located on the movement track of the stopping block, and the stopping block is slidably matched with the stopping hole.

[0027] With the above arrangement, during the rotation of the rotating shaft, the rotating shaft drives the worm to rotate synchronously. The worm meshes with the worm gear to drive the movable shaft to rotate. The movable shaft drives the second cylindrical cam to rotate. The second cylindrical cam drives the moving block to move along the path of the outer groove through the second curve groove.

[0044] The specific implementation process is as follows:

[0045] During use, the PCB board 200 to be pressed is placed on the fixed pressing plate 15. The first cylinder 16 drives the movable pressing plate 17 to move downward, thereby performing a pressing process on the PCB board 200 to be pressed to obtain the PCB board 200.

[0046] Place the PCB board 200 on the support table 31 such that the PCB board 200 is located between the two clamping plates 32 and the PCB board 200 is located below the pressing block 71.

[0047] Drive the rotation of the rotating shaft 50. The rotating shaft 50 drives the synchronous rotation of the two first cylindrical cams 51. The first cylindrical cams 51 drive the regulating block 52 to move horizontally through the first curve groove, causing the two regulating blocks 52 to approach each other. During the horizontal movement of the regulating block 52, the regulating block 52 drives the wall block 43 to move synchronously, causing the two wall blocks 43 to approach each other. During the horizontal movement of the wall block 43, the wall block 43 drives the slider 44 to move synchronously. The slider 44 also moves downward along the path of the inclined groove 42 through the auxiliary block. The slider 44 drives the support table 31 to move downward, and thus the PCB board 200 descends into the groove 30. And, after the cutting of the PCB board 200 is completed, drive the rotating shaft 50 to rotate in the reverse direction. The rotating shaft 50 drives the two first cylindrical cams 51 to rotate in the reverse direction. The first cylindrical cams 51 drive the regulating block 52 to move horizontally through the first curve groove, causing the two regulating blocks 52 to move away from each other. During the horizontal movement of the regulating block 52, the regulating block 52 drives the wall block 43 to move synchronously, causing the two wall blocks 43 to move away from each other. During the horizontal movement of the wall block 43, the wall block 43 drives the slider 44 to move synchronously. The slider 44 also moves upward along the path of the inclined groove 42 through the auxiliary block. The slider 44 drives the support table 31 to move upward, and thus can push the cut PCB board 200 upward out of the groove 30, while the excess part cut from the PCB board 200 remains in the groove 30, thereby facilitating the staff to directly take out the cut PCB board 200.

[0048] During the rotation of the rotating shaft 50, the rotating shaft 50 drives the synchronous rotation of the worm 90. The worm 90 meshes with the worm gear 92 to drive the movement of the movable shaft 91. The movable shaft 91 drives the rotation of the second cylindrical cam 100. The second cylindrical cam 100 drives the moving block 102 to move along the path of the outer groove through the second curve groove. When the stop block 103 is vertically opposite to the stop hole, the stop block 103 slides into the stop hole under the action of the fourth spring, thereby being able to stop the movable block. Furthermore, the movable block stops the rotating shaft 50 through the second cylindrical cam 100, the movable shaft 91, the worm gear 92, and the worm 90.

[0049] During the rotation of the rotating shaft 50, the rotating shaft 50 drives the two cam bodies 62 to rotate. The cam bodies 62 drive the second wedge block 61 to move upward through the C-shaped frame 64, so that the second wedge block 61 squeezes the first wedge block 60 to drive the clamping plate 32 to move laterally, causing the two clamping plates 32 to approach each other and stretching the first spring 33. The two clamping plates 32 continue to approach. When the rotating shaft 50 is stopped, the two clamping plates 32 respectively abut against both sides of the PCB board 200. The rotating shaft 50 stops the clamping plate 32 through the cam body 62, the C-shaped frame 64, the second wedge block 61, and the first wedge block 60, so that the PCB board 200 can be clamped and positioned by the two clamping plates 32. Moreover, when positioning the PCB board 200, the PCB board 200 is located in the groove 30.

[0050] During the rotation of the rotating shaft 50, the rotating shaft 50 drives the round shaft to rotate through the driving gear 74 and the driven gear 75. Since the diameter of the driving gear 74 is larger than that of the driven gear 75, the rotational speed of the round shaft is greater than that of the rotating shaft 50. The round shaft drives the lifting block 70 to move rapidly downward through the linkage gear 76 and the rack 73, and the lifting block 70 drives the pressing block 71 to move downward. When positioning the PCB board 200, the pressing block 71 abuts against the top of the PCB board 200, thereby realizing the pressing and positioning of the PCB board 200 and further strengthening the positioning effect of the PCB board 200.

[0051] During the downward movement of the pressing block 71, the pressing block 71 also squeezes the strip-shaped block 81 to move downward, reducing the distance between the strip-shaped block 81 and the bottom of the side groove 80 and compressing the second spring 82. During the reduction of the distance between the strip-shaped block 81 and the bottom of the side groove 80, the elastic block 83 deforms, increasing the protrusion amplitude of the elastic block 83. The distance between the strip-shaped block 81 and the bottom of the side groove 80 continues to decrease. When positioning the PCB board 200, the protruding part of the elastic block 83 abuts against the clamping plate 32, so that the clamping plate 32 can be limited and supported, thereby improving the positioning stability of the clamping plate 32 for the PCB board 200.

[0052] During the rotation of the movable shaft 91, the movable shaft 91 drives the swing arm 93 to rotate, causing the swing arm 93 to squeeze the support rod 84 to move in the direction of the clamping plate 32 and compressing the third spring 85. The support rod 84 continues to move. When positioning the PCB board 200, the support rod 84 passes through the opening 86 and acts on the clamping plate 32, that is, the support rod 84 abuts against the clamping plate 32, so that the clamping plate 32 can be limited and supported, thereby improving the positioning stability of the clamping plate 32 for the PCB board 200.

[0053] During the movement of the support rod 84, the support rod 84 drives the arc-shaped block 87 to move synchronously. When positioning the PCB board 200, the support rod 84 abuts against the clamping plate 32, and at the same time, the arc-shaped block 87 abuts against the protruding part of the elastic block 83, so as to stabilize the shape of the elastic block 83, thereby improving the stability of the elastic block 83 in limiting and supporting the clamping plate 32.

[0054] After completing the positioning of the PCB board 200, two third cylinders 22 are started simultaneously. The output shaft of the third cylinder 22 drives the bearing block 23 to move downward, and the bearing block 23 drives the cutting tool 25 to pass through the processing groove 72, so that the cutting tool 25 can act on the PCB board 200, and the third cylinder 22 is closed; then the motor 24 is started, and the output shaft of the motor 24 drives the cutting tool 25 to rotate; finally, the second cylinder is started, and the output shaft of the second cylinder drives the guiding block 21 to move along the path of the guiding groove 20, and the guiding block 21 drives the cutting tool 25 to move synchronously, so that the cutting tool 25 acts on the PCB board 200, that is, the two cutting tools 25 are used to cut the redundant parts on both sides of the PCB board 200.

[0055] In this embodiment, a handle 53 is fixedly connected to the worm 90. The handle 53 is located outside the base 11 and below the outer groove; the handle 53 is used to drive the rotating shaft 50 to rotate by the staff, making the operation more convenient.
