Abstract
Description
Technical Field

[0002] The CNC V-CUT machine is a device that divides PCB boards according to needs. Before the CNC V-CUT machine divides the PCB board, the PCB board needs to be positioned. The traditional CNC V-CUT machine has a relatively simple positioning and fixing method for the PCB board, which is through pneumatic clamping positioning or manual clamping positioning. The former pneumatic clamping mainly relies on the air pressure of the cylinder to make the piston of the cylinder move and drive the claws to clamp. The air pressure of the cylinder is fixed, but the aluminum substrate itself has a certain error, which is easy to cause the set value to be easily offset when positioning different aluminum substrates, resulting in reduced positioning accuracy and affecting the subsequent processing quality. The latter manual clamping is inconvenient to operate, and mainly relies on the staff's naked eye inspection and the hand's feeling of tightness to determine the positioning situation, and there is also the problem of inaccurate positioning.

DETAILED DESCRIPTION
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments; based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0024] As attached Figure 1 and attached Figure 4 As shown, a positioning device for a numerically controlled V-CUT machine comprises a positioning base frame 1, and positioning mechanisms are respectively installed on four sides of the upper side of the positioning base frame 1, two adjacent groups of the positioning mechanisms are fixedly installed on the upper side of the positioning base frame 1, and another two adjacent groups of the positioning mechanisms are slidably installed on the upper side of the positioning base frame 1;
[0025] The positioning mechanism includes a frame 2, and one side of the frame 2 close to the center of the positioning base frame 1 is a plateless structure. A support plate 3 is installed on the inner wall of the bottom of the frame 2, and grooves 4 are respectively provided on the opposite side walls of the frame 2 and on the upper side of the support plate 3. A push block 8 is slidably installed on the upper side of the bottom of the frame 2, and a positioning bent frame 9 is rotatably installed on the top of the push block 8. A limiting frame 10 is installed on the side of the positioning bent frame 9 away from the support plate 3. A limiting rod 11 is fixedly provided between the opposite side walls of the frame 2, and the limiting rod 11 is inserted in the inclined slide formed by the positioning bent frame 9 and the limiting frame 10, and the inclined slide is slidably matched with the limiting rod 11, and a rotating pressure wheel 12 is rotatably installed between the end of the positioning bent frame 9 away from the push block 8, and a pressure sensor 13 is installed on the upper side of the support plate 3.
[0026] Through the above structure, before the CNC V-CUT machine works, the PCB board is positioned through multiple groups of positioning mechanisms. First, the adjacent two sides of the PCB board are placed in the positioning mechanism fixedly installed on the upper side of the positioning chassis 1, and the PCB board is placed on the upper side of the support plate 3. The edge of the PCB board is passed into the groove 4 and supported on the front side of the push block 8. Then the two groups of movable positioning mechanisms are moved, and the other two side edges of the PCB board are respectively placed in the groove 4 and supported on the front side of the push block 8. The movable positioning mechanism continuously moves toward the fixed positioning mechanism. The edge of the PCB board pushes the push block 8 to move, so that the push block 8 is away from the support plate 3. The push block 8 drives the lower end of the positioning bent frame 9 to move, and the limit rod 11 slides inside the inclined slide formed by the positioning bent frame 9 and the limit frame 10, so that the other end of the positioning bent frame 9 rotates downward, and the rotating pressure wheel 12 is pressed on the upper side of the PCB board to position the PCB board. The pressure transmitted from the lower side of the PCB board is detected by the pressure sensor 13, and the displacement mechanism is processed. The specific structure is as follows:
[0027] Combined with Figure 2 and attached Figure 3 As shown, displacement mechanisms are respectively installed on the lower sides of the two groups of positioning mechanisms slidably arranged on the upper side of the positioning base 1, and the displacement mechanisms include a threaded shaft 15 installed through the side wall of the positioning base 1, and a motor 16 for driving the threaded shaft 15 is installed on the outer wall of the positioning base 1. A moving block 17 is threadedly connected to the outer side of the threaded shaft 15, and the upper side of the moving block 17 is connected to the lower side of the frame 2. A control switch 19 is installed on the outer wall of one side of the positioning base 1, and the control switch 19 is respectively connected to the two groups of motors 16 and the pressure sensor 13.
[0028] Through the above structure, the two groups of motors 16 are started to rotate through the control switch 19, the threaded shaft 15 is driven to rotate through the motor 16, the moving block 17 is driven to move horizontally through the threaded shaft 15, and the positioning mechanism is driven to move through the moving block 17. The data detected in the pressure sensor 13 is transmitted to the control switch 19. After the pressure value reaches the set value, the corresponding motor 16 is turned off through the control switch 19, so that the positioning mechanism stops moving, thereby preventing the rotating pressure wheel 12 from exerting excessive pressure on the PCB board.
[0029] Combined with Figure 1 As shown, a support pile 14 is installed at the center of the lower side of the positioning base frame 1, one end of the threaded shaft 15 is rotatably connected to the side wall of the support pile 14, and a slideway 18 for the moving block 17 to slide through is provided on the upper side wall of the positioning base frame 1.
[0030] Through the above structure, the support pile 14 stabilizes one end of the threaded shaft 15 to prevent the threaded shaft 15 from causing the positioning mechanism to shake and causing damage to the PCB board. When the moving block 17 moves, the slide 18 limits the moving block 17 to prevent the moving block 17 from rotating with the threaded shaft 15.
[0031] Combined with Figure 1 and attached Figure 4 As shown, the push block 8 is located on the side of the support plate 3 away from the center of the positioning base frame 1, and two groups of slide grooves 5 are provided at the bottom of the frame 2. The push block 8 is an L-shaped structure and the lower part slides inside the slide groove 5. The slide groove 5 is close to the side of the center of the positioning base frame 1 and is provided with a mounting block 6 below the support plate 3. A spring 7 is installed between the mounting block 6 and the lower part of the push block 8, and a rubber protective layer is installed on the outer side of the rotating pressure wheel 12.
[0032] Through the above structure, when the push block 8 is pushed by the PCB board, the push block 8 slides within the limit position inside the slide groove 5 and pulls the spring 7 to expand. When the movable positioning mechanism moves away from the fixed positioning mechanism, the push block 8 is driven to return to its original position through the resilience of the spring 7, so that the positioning bending frame 9 rotates, and the rotating pressure wheel 12 releases the limit position of the PCB board. The rubber protective layer installed on the outside of the rotating pressure wheel 12 prevents the rotating pressure wheel 12 from being hard squeezed with the PCB board to cause collision damage.
[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
[0035] The above describes the utility model and its implementation methods, which are not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and do not deviate from the purpose of the invention of the utility model, they can creatively design a structure and embodiment similar to the technical solution, which should belong to the protection scope of the utility model.
