[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1 - Figure 6 , the utility model provides a technical solution: Example 1:

[0029] A PCB automatic depaneling machine includes an automatic depaneling machine 1 and a slitting wheel 2. The slitting wheel 2 is driven and connected to the interior of the automatic depaneling machine 1. A storage plate 3 is fixedly connected to one side of the automatic depaneling machine 1. A guide frame 4 is provided on the top of the storage plate 3. The connection between the guide frame 4 and the storage plate 3 is supported by a support block 5. Two positioning mechanisms are provided on the top of the guide frame 4:

[0030] The positioning mechanism includes a sliding sleeve 6 that is slidably connected to the surface of the guide frame 4. A guide hole 7 is provided on one side of the sliding sleeve 6 for use with the guide frame 4. A threaded rod 8 is threadedly connected to the top of the sliding sleeve 6. A threaded hole 9 is provided on the top of the sliding sleeve 6 for use with the threaded rod 8. A clamping block 10 is provided at the bottom of the threaded rod 8. A buffer mechanism is provided between the clamping block 10 and the threaded rod 8. An adjustment mechanism is provided on one side of the sliding sleeve 6.

[0031] In this embodiment, it is taken into consideration that the fully automatic PCB board splitting machine often lacks the function of positioning the PCB board when cutting the PCB board, especially for some larger PCB boards, which require more cutting when cutting and are prone to shaking, thereby affecting the cutting effect. Therefore, by providing a positioning mechanism, after placing the PCB board on the storage plate 3, the user can insert a finger into the screwing groove and rotate the screwing block 21. The screwing block 21 will drive the threaded rod 8 to rotate in the threaded hole 9, so that the threaded rod 8, the housing 11 and the pressing block 10 gradually move downward until the anti-slip pad 22 at the bottom of the pressing block 10 is in close contact with the top of the PCB board. This can complete the fixing of the PCB board, avoid shaking of the PCB board during the cutting process, and improve the cutting effect.

[0032] The invention solves the problem that the fully automatic PCB board splitting machine often lacks the function of positioning the PCB board when cutting the PCB board, especially some larger PCB boards, which have a large amount of cutting force during cutting and are prone to shaking, thus affecting the cutting effect.

[0033] Preferably, a twisting block 21 is fixedly connected to the top of the threaded rod 8 , and four twisting grooves are formed on the surface of the twisting block 21 .

[0034] In this embodiment, by providing the twisting block 21 and the twisting groove, when the threaded rod 8 needs to be rotated, the twisting block 21 can be easily rotated by inserting a finger into the twisting groove to drive the threaded rod 8 to rotate.

[0035] Preferably, the bottom of the pressing block 10 is fixedly connected with an anti-skid pad 22 , and the material of the anti-skid pad 22 is rubber.

[0036] In this embodiment, the anti-slip pad 22 is provided to increase the friction between the pressing block 10 and the PCB board, thereby further improving the stability of the PCB board during positioning. Example 2:

[0037] On the basis of Example 1, the positioning mechanism in this embodiment can position the PCB board through the clamping block 10 to avoid shaking during slitting of the PCB board and improve the slitting effect. However, considering that the material of the PCB board itself is relatively brittle, direct hard contact of the clamping block 10 can easily cause damage to the PCB board. The buffer mechanism in this application includes a shell 11 fixedly connected to the bottom of the threaded rod 8, a spring 12 is provided inside the shell 11, the bottom of the spring 12 is fixedly connected to a buffer block 13, the bottom of the buffer block 13 is fixedly connected to a buffer rod 14, the bottom of the buffer rod 14 passes through the bottom of the shell 11, and is fixedly connected to the top of the clamping block 10.

[0038] In this embodiment, considering that the PCB is relatively brittle, direct, hard contact of the pressing block 10 may easily damage the PCB. Therefore, a buffer mechanism is provided. When the pressing block 10 contacts the PCB, the pressing block 10 drives the buffer rod 14 and the buffer block 13 to move upward. The buffer block 13 drives the spring 12 to contact and squeeze the inner wall of the housing 11, thereby achieving a buffering effect and preventing damage to the PCB.

[0039] The problem that the PCB board is easily damaged by direct hard contact of the pressing block 10 due to the brittle material of the PCB board is solved. Example 3:

[0040] On the basis of Example 1, the positioning mechanism in this embodiment can achieve the positioning effect by making the clamping block 10 contact the PCB board. However, considering the different sizes of the PCB boards, if the clamping block 10 cannot contact it, the clamping and positioning effect cannot be achieved. The adjustment mechanism in this application includes an adjustment block 15 fixedly connected to one side of the sliding sleeve 6, and a pull ring 16 is provided on the top of the adjustment block 15. The bottom of the pull ring 16 is fixedly connected to a linkage block 17, and the bottom of the linkage block 17 is fixedly connected to an adjustment rod 18. The bottom of the adjustment rod 18 passes through the bottom of the adjustment block 15, and the top of the guide frame 4 is provided with an adjustment hole 19 used in conjunction with the adjustment rod 18.

[0041] In this embodiment, taking into account the different sizes of PCB boards, if the clamping block 10 cannot contact it, the clamping and positioning effect cannot be achieved. Therefore, an adjustment mechanism is provided, which can drive the linkage block 17 and the adjustment rod 18 to move upward by pulling the pull ring 16 upward, so that the adjustment rod 18 leaves the adjustment hole 19. After that, the position of the sliding sleeve 6 can be adjusted along the trajectory of the guide frame 4 and the guide hole 7. After reaching the appropriate position, the pull ring 16 is released, and the tension generated by the tension spring 20 drives the linkage block 17 and the adjustment rod 18 to move downward, so that the adjustment rod 18 enters the corresponding adjustment hole 19, completing the fixation of the sliding sleeve 6. At this time, the clamping position of the clamping block 10 is also adjusted as the position of the sliding sleeve 6 is adjusted, so that it can effectively fix the PCB board when the threaded rod 8 is rotated later.

[0042] The problem that the pressing and positioning effect cannot be achieved if the pressing block 10 cannot contact the PCB board due to different sizes of the PCB board is solved.

[0043] Preferably, a tension spring 20 is fixedly connected to the bottom of the linkage block 17 , and the bottom of the tension spring 20 is fixedly connected to the top of the adjustment block 15 .

[0044] In this embodiment, a tension spring 20 is provided so that when the pull ring 16 is loosened, the tension generated by the tension spring 20 drives the linkage block 17 and the adjustment rod 18 to reset, so that the adjustment rod 18 can enter the interior of the adjustment hole 19, thereby playing a reset role.

[0045] Preferably, there are several adjustment holes 19 , which are evenly distributed on the top of the guide frame 4 .

[0046] In this embodiment, by providing a plurality of adjustment holes 19 , after the position of the sliding sleeve 6 is adjusted, the adjustment rod 18 can be made to enter the corresponding adjustment hole 19 to complete the rapid positioning of the sliding sleeve 6 .

[0047] Working principle: After placing the PCB on the storage plate 3, the user inserts a finger into the corresponding screwing groove and rotates the screwing block 21. The screwing block 21 drives the threaded rod 8 to rotate in the threaded hole 9, causing the threaded rod 8, the housing 11 and the pressing block 10 to gradually move downward until the anti-slip pad 22 at the bottom of the pressing block 10 is in close contact with the top of the PCB. This completes the fixation of the PCB, prevents the PCB from shaking during the slitting process, and improves the slitting effect.

[0048] When the pressing block 10 contacts the PCB, the pressing block 10 drives the buffer rod 14 and the buffer block 13 to move upward, and the buffer block 13 drives the spring 12 to contact and squeeze the inner wall of the housing 11, thereby achieving a buffering effect and preventing damage to the PCB.

[0049] At the same time, by pulling the pull ring 16 upward, the linkage block 17 and the adjusting rod 18 can be driven to move upward, so that the adjusting rod 18 leaves the adjusting hole 19. Then, the position of the sliding sleeve 6 can be adjusted along the trajectory of the guide frame 4 and the guide hole 7. After reaching the appropriate position, the pull ring 16 is released, and the tension generated by the tension spring 20 will drive the linkage block 17 and the adjusting rod 18 to move downward, so that the adjusting rod 18 enters the corresponding adjusting hole 19, completing the fixation of the sliding sleeve 6. At this time, the clamping position of the clamping block 10 is also adjusted as the position of the sliding sleeve 6 is adjusted, so that it can effectively fix the PCB board when the threaded rod 8 is rotated later.

[0050] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
