[0046] The present invention will be further described below with reference to embodiments.

[0047] As a first embodiment of this application:

[0048] Reference Appendix Figures 1 to 8 As shown, a printed circuit board depaneling machine includes a main control cabinet 1. The main control cabinet 1 is equipped with a drive unit 11, a moving unit 12, a knife holder 13, a roller cutter 14, and a depaneling table 15. The drive unit 11 drives the moving unit 12 to move the knife holder 13 and the roller cutter 14 to achieve depaneling.

[0049] It also includes: a linear separation support mechanism 2, which includes: a linkage component 21 and several support components 22. The linkage component 21 is connected to the cutter holder 13 and moves synchronously with the cutter holder 13. Several support components 22 are evenly distributed on the separation table 15. During the translation process, the linkage component 21 can drive the support components 22 to avoid the cutting path of the roller cutter 14 one by one, and the undriven support components 22 always provide support for the circuit board.

[0050] The purpose of setting up several support components 22 is to avoid large areas of suspension caused by a single support structure when avoiding the circuit board during the cutting process by using segmented support. This ensures that only a very small area of ​​the circuit board in contact with the roller cutter 14 is temporarily unsupported during the cutting process, while the rest of the area remains in a stable support state, thereby dispersing the cutting stress.

[0051] In specific implementation, the linkage assembly 21 comprises a linkage rod 211 and a pressing pulley 212. The linkage rod 211 is fixed to the outer wall of one side of the tool seat 13. The pressing pulley 212 is rotationally connected to the lower end of the linkage rod 211 and is located on the side of the hob 14 in the direction of the cutting plate. Specifically, the pressing pulley 212 is located on the side of the hob 14 in the direction of the cutting plate, which can make the pressing pulley 212 contact the supporting assembly 22 before the hob 14, so as to ensure that the supporting assembly 22 avoids the hob 14 in advance and avoids interference between the two. The structure that the pressing pulley 212 is rotationally connected to the linkage rod 211 can replace sliding friction with rolling friction, reduce the influence on the translation stability of the tool seat 13 during linkage, and ensure cutting accuracy.

[0052] In specific implementation, each supporting assembly 22 comprises a supporting box 221, a supporting block 222, a supporting spring 223, a curved rod 224 and a triangular block 225. The supporting box 221 is fixed to the outer wall of the side of the cutting plate table 15 close to the driving unit 11. The supporting block 222 is slidingly arranged in the supporting box 221. The supporting spring 223 is connected between the bottom of the supporting block 222 and the inner bottom surface of the supporting box 221. The curved rod 224 is fixedly connected to the outer wall of the side of the supporting block 222 away from the cutting plate table 15. The triangular block 225 is fixedly connected to the end of the curved rod 224. The triangular block 225 is in isosceles triangular structure. The triangular block 225 is located on the translation path of the pressing pulley 212.

[0053] The triangular block 225 adopts isosceles triangular structure, which can convert the horizontal pushing force of the pressing pulley 212 into the vertical downward displacement force of the supporting block 222 by using the inclined surface, so as to make the supporting block 222 sink stably. The supporting spring 223 can drive the supporting block 222 to automatically reset after the pressing pulley 212 is separated from the triangular block 225, so as to ensure the supporting effectiveness of subsequent cutting plate operation. The supporting block 222 is slidingly arranged in the supporting box 221, which can limit the movement direction of the supporting block 222 and avoid deviation to cause supporting failure.

[0054] As a second embodiment of the present application:

[0055] Referring to the accompanying drawings, Figures 9 to 11 As shown in the drawings, the above cutting plate machine further comprises a positioning and pushing mechanism 3. The positioning and pushing mechanism 3 comprises a pushing assembly 31 and a positioning assembly 32. The pushing assembly 31 is arranged on the top surface of the cutting plate table 15. The positioning assembly 32 is integrated in the cutting plate table 15.

[0056] In specific implementation, the pushing assembly 31 comprises a servo air cylinder 311, a limiting groove plate 312, two L-shaped clamping blocks 313, a bidirectional threaded rod 314, and a photoelectric sensor 315. The servo air cylinder 311 is fixedly installed on the top surface of the board separating table 15. The limiting groove plate 312 is fixed to the end of the telescopic rod of the servo air cylinder 311. The two L-shaped clamping blocks 313 are slidingly arranged inside the limiting groove plate 312. The bidirectional threaded rod 314 is threadedly arranged between the two L-shaped clamping blocks 313. The photoelectric sensor 315 is fixedly installed on the outer wall of one side of the board separating table 15, and the detection end thereof is collinear with the cutting and board separating movement path of the rotary knife 14.

[0057] The structure that the bidirectional threaded rod 314 is threadedly arranged between the two L-shaped clamping blocks 313 can realize the synchronous approach or departure of the two L-shaped clamping blocks 313 by rotating the bidirectional threaded rod 314, thereby adapting to circuit boards of different widths. The limiting groove plate 312 plays a guiding and limiting role on the two L-shaped clamping blocks 313, avoiding the deviation of the L-shaped clamping blocks 313 during clamping. The detection end of the photoelectric sensor 315 is collinear with the cutting path of the rotary knife 14, and can send a stop signal to the servo air cylinder 311 in time when the photoelectric sensor 315 is triggered by the edge of the circuit board to be cut, thereby ensuring the accurate alignment of the cutting part to be cut with the blade edge of the rotary knife 14, and replacing manual alignment.

[0058] In specific implementation, the positioning assembly 32 comprises a rectangular cavity 321, a plurality of array holes 322, and an external air duct 323. The rectangular cavity 321 is arranged in the board separating table 15. The plurality of array holes 322 are uniformly distributed on the board separating table 15 at positions corresponding to the rectangular cavity 321 and arranged in a rectangular array. The external air duct 323 is arranged in the rectangular cavity 321 and extends to one side of the outer wall of the board separating table 15. The external air duct 323 is used for external connection of a negative pressure device.

[0059] The arrangement of the plurality of array holes 322 in a rectangular array can make the negative pressure suction force uniformly act on the bottom surface of the circuit board, thereby avoiding the displacement of the circuit board during cutting due to insufficient local suction force. The arrangement of the rectangular cavity 321 provides a channel for negative pressure conduction, thereby ensuring that each array hole 322 can obtain stable suction force. The design of integrating the positioning assembly 32 in the interior of the board separating table 15 simplifies the structure of the top surface of the board separating table 15 and avoids interference with the movement of the pushing assembly 31.

[0060] As a third embodiment of the present application:

[0061] As Figures 12 to 14As shown in the above printed circuit board splitter, further comprising a feeding mechanism 4, which is provided on the top of the main control cabinet 1; the core function of the feeding mechanism 4 is to realize the automatic feeding of the circuit board after the splitting is completed, and at the same time, the receiving area 41 can place the containing container or the docking rear end receiving device, so that the fed circuit board can be collected in order; compared with the direct falling mode of the circuit board after splitting in the prior art, this mode can avoid the collision and friction between the circuit boards, and further prevent the edge collapse, pad falling or line damage of the circuit board.

[0062] In particular implementation, the feeding mechanism 4 includes a receiving area 41, two guide rails 42, a concave plate 43, an electric control telescopic rod 431, a stepping motor 44, a rotating shaft 45 and a plurality of tapping wheels 46, the receiving area 41 is provided on the top of the main control cabinet 1 and located on the side away from the splitting table 15 of the hob 14, the two guide rails 42 are fixedly arranged on the top surface of the receiving area 41, the concave plate 43 is slidingly arranged on the two guide rails 42, the electric control telescopic rod 431 is fixedly installed on the receiving area 41, and the telescopic rod end thereof is fixedly connected with the concave plate 43, the stepping motor 44 is fixedly installed on one side of the top of the concave plate 43, the rotating shaft 45 is fixedly connected with the output shaft end of the stepping motor 44, and the plurality of tapping wheels 46 are coaxially fixed on the outer circumferential surface of the rotating shaft 45 and are equidistantly distributed, a plurality of annularly distributed tapping grooves 47 are formed in each tapping wheel 46;

[0063] The two guide rails 42 provide guidance for the translation of the concave plate 43, ensuring that the concave plate 43 stably approaches or moves away from the circuit board with the tapping wheels 46; the equidistant distribution of the plurality of tapping wheels 46 and the design of the plurality of tapping grooves 47 formed in each tapping wheel 46 can simultaneously clamp a plurality of split completed circuit boards, improving the feeding efficiency; the structure of the coaxial fixation of the tapping wheels 46 on the rotating shaft 45 ensures the synchronous rotation of all the tapping wheels 46, ensuring the precise correspondence of the clamping position of each circuit board.

[0064] Further, the soft rubber pad is arranged on the groove surface of the tapping groove 47, and the angle of rotation of the rotating shaft 45 and the tapping wheel 46 driven by the stepping motor 44 each time is the included angle between the adjacent two tapping grooves 47; the arrangement of the soft rubber pad can avoid scratching the surface of the circuit board or damaging the pad during clamping, and plays a protective role; the design that the angle of rotation of the rotating shaft 45 and the tapping wheel 46 driven by the stepping motor 44 each time is consistent with the included angle of the adjacent tapping grooves 47 can realize the continuous and orderly feeding operation after the next tapping groove 47 is precisely rotated to the position aligned with the next circuit board after one circuit board is clamped and transferred.

[0065] The complete working and use principle of the above embodiment are as follows:

[0066] The staff places the circuit board to be separated on the array hole 322 area on the separating table 15, the external airway 323 connects the negative pressure device to form negative pressure in the rectangular cavity 321, the circuit board is adsorbed and fixed through the array hole 322, and displacement in subsequent actions is avoided. The bidirectional threaded rod 314 is rotated, the two L-shaped clamping blocks 313 are adjusted to slide along the limiting groove plate 312, the non-circuit edge of the circuit board is clamped, and the double fixing of the circuit board is completed.

[0067] Then, the servo cylinder 311 of the positioning and pushing mechanism 3 is started, the servo cylinder 311 pushes the limiting groove plate 312 and the circuit board to translate towards the hob 14. When the edge to be cut of the circuit board moves to the detection area of the photoelectric sensor 315, the photoelectric sensor 315 is triggered and sends a stop signal, and the servo cylinder 311 immediately stops the action, at this time, the cutting part of the circuit board is accurately aligned with the blade edge of the hob 14.

[0068] Immediately, the driving unit 11 is started, the driving unit 11 drives the moving unit 12, the tool holder 13 and the hob 14 to translate synchronously, and the cutting and separating operation is started. The linkage assembly 21 connected with the tool holder 13 translates with the tool holder 13, and the abutting pulley 212 contacts the triangular block 225 on the path before the hob 14, the horizontal thrust is converted into the vertical downward pressure of the supporting block 222 by means of the inclined surface guiding action of the triangular block 225, the supporting block 222 is compressed to sink into the supporting box 221, and the hob 14 is avoided to form a cutting path. After the hob 14 passes through the supporting assembly 22, the abutting pulley 212 is separated from the triangular block 225, the supporting spring 223 rebounds to drive the supporting block 222 to reset, and the supporting block 222 continues to form support to the subsequent area; the remaining supporting assemblies 22 that are not driven always maintain the supporting state, and large-area suspension of the circuit board is prevented throughout the process.

[0069] When the cutting and separating operation is completed, the negative pressure device is closed, and the adsorption force of the array hole 322 on the circuit board disappears. The feeding mechanism 4 is started, the electric control telescopic rod 431 pushes the concave plate 43 to translate along the guide rail 42 towards the separating table 15, the separating groove 47 on the separating wheel 46 is aligned with the cut circuit board.
