[0021] Step 2: After the strip cutting is completed, the transfer adsorption component starts to work, the slide seat slides on the rodless cylinder and the sleeve slides on the lead screw, so that the adsorption plate 2 enters the primary cutting chamber to adsorb the stripped massage circuit board, and transfers the massage circuit board to the fixed seat 2 in the secondary cutting chamber to clamp it for secondary longitudinal cutting;

Then the grinding roller enters the longitudinal cutting position, and the longitudinal end surface of the secondary longitudinally cut circuit board is polished by the grinding roller. After grinding, the pressing block is opened, and the grinding roller enters between the two pressing blocks at the next position. Then the pressing block repeatedly fixes the circuit board until all the circuit boards are longitudinally cut.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. By setting up a grinding component, after the grinding roller contacts the end face of the circuit board, the two fitting blocks contact the upper and lower end faces of the circuit board respectively to form a grinding area to avoid splashing of residual scraps when the grinding roller is horizontally grinding. Then the linear guide rail drives the vertical plate to slide horizontally to horizontally grind the end face of the circuit board. After the grinding is completed, the grinding roller enters between the two pressing blocks at the front end, that is, the grinding roller and the longitudinal cutting position of the circuit board are in line. The synchronous cylinder pushes the pressing block to fix the polished end face of the circuit board after the first cutting. Then the laser head in the secondary cutting chamber cuts the massager circuit board longitudinally to obtain To small pieces of circuit boards, the grinding roller then enters the longitudinal cutting position. Since the circuit boards have been formed into strips with a small width, the two-way screw drives the corresponding grinding roller to move to the middle of the longitudinal cutting end face to complete the secondary grinding of the longitudinal end face of the entire circuit board. After the grinding is completed, the pressing block is opened, and the grinding roller enters between the two pressing blocks at the next position. Then the pressing block repeatedly fixes the circuit board until all the circuit boards are longitudinally cut. The scraps in the transverse and longitudinal grinding are collected in the blanking seat 2 along the longitudinal cutting path, so that small pieces of finished massager circuit boards can be obtained at one time, with high production efficiency.

[0026] 2. The first slitting is performed along the direction of the cutting groove, and the residual scraps from the slitting fall along the cutting groove to the blanking seat 1 for centralized collection. The blanking seat 1 is rolled out by the track in the first slitting chamber to the position of the blanking port; during the second slitting, the blanking seat 2 is mainly used to collect the scraps generated by the grinding of the transverse end face of the massager circuit board after the strips are formed and the second longitudinal slitting. The blanking seat 2 is rolled out by the track in the second slitting chamber to the position of another blanking port. A collection container is placed under the blanking port in advance. The lever is pushed, and the lever slides in the slideway, and pushes the limiting plate to slide horizontally. At this time, the push bar pushes the scraps forward to concentrate the distance. When the push bar moves to the position of the ash falling groove, the push bar slides downward under the sliding of the inclined surface and the slope, so that the spring is contacted and compressed and elastically stretched, and the push bar pushes one end of the blocking plate downward. At this time, the blocking plate rotates and opens, which is convenient for collecting and utilizing the scraps. After that, the push bar slides along the slope to the bottom surface of the inner cavity of the blanking seat, and the torsion spring returns to its initial position, and the blocking plate continues to block the ash falling groove;

[0027] 3. By setting up the transfer adsorption component, initially, the slide and the sleeve are located in the middle of the inner cavity of the material distribution channel. After one cutting is completed, the slide slides on the rodless cylinder toward the direction of the primary cutting cavity, and at the same time, the sleeve slides on the lead screw and moves toward the primary cutting cavity. At this time, the adsorption plate 2 enters the primary cutting cavity to adsorb the massager circuit board into strips. After that, the slide and the sleeve move toward the direction of the secondary cutting cavity at the same time, and transfer the massager circuit board to the fixed seat 2 in the secondary cutting cavity for horizontal clamping, thereby realizing the transfer of the massager circuit board after strip cutting.

After the massager circuit board is loaded by the primary cutting bearing assembly, it follows the track 5 to the primary cutting chamber for a horizontal strip cutting. Then, the transfer adsorption assembly adsorbs the already cut massager circuit board into the fixed seat 2 31 in the secondary cutting bearing assembly for horizontal clamping. Then, the two moving strips 34 approach each other, driving the corresponding grinding rollers 41 to contact the end face of the strip circuit board. Then, the upper and lower fitting blocks 39 move downward and upward respectively, contacting the upper and lower surfaces of the circuit board respectively, forming a closed space for grinding. The vertical plate 36 is driven to slide horizontally by the linear guide rail 1 35, and then the end face of the strip circuit board is horizontally grinded.

The corresponding moving strip plate 34 is controlled to slide on the bottom surface of the inner cavity of the fixed seat 31 through the rotation of the bidirectional screw rod 32. The rotation of the bidirectional screw rod 32 is divided into two stages. When the strips are formed, When the transverse end face of the massager circuit board is polished, the movable strip 34 drives the grinding roller 41 to contact the transverse end face of the circuit board.

[0053] Step 2: After the strip cutting is completed, the transfer adsorption assembly starts to work, the slide seat 12 slides on the rodless cylinder 11 and the sleeve slides on the lead screw 13, so that the adsorption plate 14 enters the primary cutting chamber to adsorb the stripped massage circuit board, and transfers the massage circuit board to the fixed seat 31 in the secondary cutting chamber 10 to clamp it for secondary longitudinal cutting;

[0054] Step 3: Before the secondary slitting, the two moving strips 34 approach each other, driving the corresponding grinding rollers 41 to contact the end faces of the finished circuit boards, and then the upper and lower laminating blocks 39 move downward and upward respectively, contacting the upper and lower surfaces of the circuit boards to form a closed grinding space, and the vertical plate 36 slides horizontally on the linear guide rail 1 35 to grind the end faces of the finished circuit boards horizontally;

[0055] Step 4. After grinding, the grinding roller 41 enters between the two pressing blocks at the front end, and the pressing block is pushed by the synchronous cylinder to fix the polished end surface of the circuit board after the first cutting. Then, the laser head 8 in the secondary cutting chamber 10 cuts the massager circuit board longitudinally to obtain small pieces of circuit boards. Then, the grinding roller 41 enters the longitudinal cutting position, and the grinding roller 41 grinds the longitudinal end surface of the secondary longitudinally cut circuit board. After grinding, the pressing block is opened, and the grinding roller 41 enters between the two pressing blocks at the next position. Then, the pressing block repeatedly fixes the circuit board until all the circuit boards are longitudinally cut.

[0056] When the present invention is in use, a grinding assembly is set up. After the grinding roller 41 contacts the end face of the circuit board, the two fitting blocks 39 contact the upper and lower end faces of the circuit board respectively to form a grinding area to avoid splashing of residual scraps when the grinding roller 41 is horizontally grinding. Then the linear guide 35 drives the vertical plate 36 to slide horizontally to horizontally grind the end face of the circuit board. After the grinding is completed, the grinding roller 41 enters between the two pressing blocks at the front end, that is, the grinding roller 41 is in line with the longitudinal cutting position of the circuit board. The pressing block is pushed by the synchronous cylinder to fix the polished end face of the circuit board after the first cutting. Then the laser head 8 in the secondary cutting chamber 10 is used to massage the massage circuit board. The board is cut longitudinally to obtain small pieces of circuit boards, and then the grinding roller 41 enters the longitudinal cutting position. Since the circuit board has been formed into strips with a small width, the bidirectional screw 32 drives the corresponding grinding roller 41 to move to the middle of the longitudinal cutting end face to complete the secondary grinding of the longitudinal end face of the entire circuit board. After the grinding is completed, the pressing block is opened, and the grinding roller 41 enters between the two pressing blocks at the next position. Then the pressing block repeatedly fixes the circuit board until the longitudinal cutting of the circuit board is completed. The scraps in the transverse and longitudinal grinding are collected in the blanking seat 15 along the longitudinal cutting path, and small pieces of finished massager circuit boards can be obtained at one time, with high production efficiency.

[0057] The first cutting is cut along the direction of the cutting groove 20, and the residual scraps of the cutting fall along the cutting groove 20 to the blanking seat 16 for centralized collection. The blanking seat 16 is rolled out by the track 5 in the first cutting chamber to the position of the blanking port 2; during the second cutting, the blanking seat 2 15 is mainly used to collect the scraps generated by the grinding of the transverse end face of the massager circuit board after the strips are formed and the second longitudinal cutting. The blanking seat 2 15 is rolled out by the track 5 in the secondary cutting chamber 10 to the position of another blanking port 2. A collection container is placed under the blanking port 2 in advance, and the lever 18 is pushed. The lever 18 slides in the slideway 17 and pushes the limiting plate 25 to slide horizontally. At this time, the push bar 27 pushes the scraps forward to concentrate the distance. When the push bar 27 moves to the position of the ash falling groove 28, the push bar 27 slides downward under the sliding of the inclined surface and the slope, so that the spring 26 is contacted and compressed and elastically stretched, and the push bar 27 pushes one end of the blocking plate 29 downward. At this time, the blocking plate 29 rotates and opens, which is convenient for collecting and utilizing the scraps. After that, the push bar 27 slides along the slope to the bottom surface of the inner cavity of the blanking seat 16, and the torsion spring returns to its initial position. The blocking plate 29 continues to block the ash falling groove 28;

[0058] By setting the transfer adsorption component, initially, the slide 12 and the sleeve are located in the middle of the inner cavity of the dividing channel 9. After one cutting is completed, the slide 12 slides on the rodless cylinder 11 toward the direction of the primary cutting cavity, and at the same time, the sleeve slides on the lead screw 13 and moves toward the primary cutting cavity. At this time, the adsorption plate 14 enters the primary cutting cavity to adsorb the massager circuit board into strips. Then, the slide 12 and the sleeve move toward the direction of the secondary cutting cavity 10 at the same time, and the massager circuit board is transferred to the fixed seat 2 31 in the secondary cutting cavity 10 for horizontal clamping, thereby realizing the transfer of the massager circuit board after the strip cutting.
