DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] See also Figure 1-5 , the utility model provides an embodiment: an adjustable positioning fixture structure for PCB board processing, comprising: a fixture assembly frame 1;

[0030] Also includes:

[0031] A first screw module 2 is installed in a slot on the inner wall of one side of the fixture assembly frame 1, and two first screw modules 2 are installed in front and behind. A first slide groove 7 is opened on the inner wall of the other side of the fixture assembly frame 1, and a first driven slider 8 is installed inside the first slide groove 7;

[0032] A fixture adjustment seat 6 is installed between the first lead screw module 2 and the first driven slider 8 through a connecting member 5. The upper surface of the fixture adjustment seat 6 is provided with two left-right symmetrical moving grooves 9;

[0033] A second lead screw module 10 is installed in a slot on the inner wall of one side of the moving groove 9. A second slide groove 19 is opened on the inner wall of the other side of the moving groove 9. A second driven slider 18 is installed inside the second slide groove 19.

[0034] A clamping assembly 11, which is installed between the second driven slider 18 and the second screw module 10;

[0035] By setting the first lead screw module 2, the first slide slot 7, the clamp adjustment seat 6, the moving slot 9, the second lead screw module 10, the second slide slot 19, and the clamping assembly 11, the clamp can be provided with an adjustable moving structure, through which the clamp can be moved accordingly according to PCB boards of different sizes, and the clamping assembly 11 can be moved to the four corners of the PCB board by moving, and the four corners of the PCB board are limited so that the PCB board is fixed therebetween;

[0036] Specifically, the first screw module 2 is used to drive the clamp adjustment seat 6 to move, and the distance between the two clamp adjustment seats 6 is adjusted by moving to adjust the length of the PCB board; the second screw module 10 drives the clamping assembly 11 to move left and right, and adjusts the clamping assembly 11 to the required position according to the width of the PCB board, thereby realizing the adjustment and positioning process of the PCB board;

[0037] The above structure uses an electric method to realize the moving adjustment process, which is more convenient to use and is convenient for use in PCB board processing;

[0038] The first slide groove 7 and the first driven slide block 8 are used to follow the movement of the clamp adjustment seat 6 and make the movement of the clamp adjustment seat 6 smoother and more stable;

[0039] The second slide groove 19 and the second driven slider 18 are used to follow the movement of the clamping assembly 11 and make the movement of the clamping assembly 11 smoother and more stable.

[0040] See also Figure 4 The clamping assembly 11 includes an L-shaped anti-skid rubber platform 12, a flip frame 14 is provided at the middle position of the outer wall of the L-shaped anti-skid rubber platform 12, a motor shaft 13 is installed inside the flip frame 14, and both ends of the motor shaft 13 extend to the outside of both ends of the flip frame 14;

[0041] The L-shaped anti-skid rubber table 12 is used to place the PCB board to be processed. The anti-skid rubber is used as the table surface to prevent the bottom of the PCB board from directly contacting the table body, thereby preventing the PCB board from being damaged. In addition, the anti-skid rubber table 12 can also improve the anti-skid property and further improve the clamping stability.

[0042] One end of the motor shaft 13 is used to connect to a motor (not shown in the figure). The motor drives the motor shaft 13 to drive the flip frame 14 to rotate. The rotation of the flip frame 14 drives the pressure plate 15 to move, so that the pressure plate 15 can press and restrict the PCB board by flipping and pressing down.

[0043] See also Figure 4 , a plurality of press plates 15 arranged in a transverse interval are provided on the side wall of the turning frame 14;

[0044] There are multiple pressing plates 15, and the pressing plates 15 are of a toothed plate structure with many pressing points, which can effectively limit the downward pressure on the PCB board.

[0045] See also Figure 5 , a rubber pad 16 is provided on the lower surface of the pressing plate 15;

[0046] The rubber pad 16 is used to prevent the pressing plate 15 from directly contacting the PCB board, so that the positioning process will not be damaged due to the pressing plate 15 pressing down and touching. The rubber pad 16 also has anti-skid properties, which can improve the anti-skid effect and prevent the PCB board from moving.

[0047] See also Figure 5 , a pressure sensor 17 is installed in the groove of the outer wall of the rubber pad 16;

[0048] The pressure sensor 17 is used to detect pressure changes and feed back signals to the controller. The controller pre-sets a pressure value range and limits the motor flip angle according to the pressure value range to avoid excessive downward pressure that may damage or crack the PCB board.

[0049] See also Figure 1 The first screw module 2 and the second screw module 10 both include a ball screw 3, a screw slider 4 is provided on the outer wall of the ball screw 3, and the first screw module 2 is slidably connected to the clamp adjustment seat 6 through the screw slider 4, and the second screw module 10 is slidably connected to the clamping assembly 11 through the screw slider 4;

[0050] The end of the ball screw 3 is used to connect to a screw motor (not shown in the figure), which drives the ball screw 3 to rotate, causing the screw slider 4 to move linearly on the ball screw 3, driving the components at the corresponding screw slider 4 to realize displacement adjustment operation.

[0051] See also Figure 1The bottom of the outer walls on both sides of the fixture assembly frame 1 are integrally provided with a positioning seat 20, and the outer wall of the positioning seat 20 is provided with a plurality of positioning holes 21 arranged at intervals in a transverse direction;

[0052] The positioning seat 20 and the positioning hole 21 are used to facilitate the user to assemble the fixture assembly frame 1 on the processing table to improve stability and firmness.

[0053] Working principle: When in use, the fixture assembly frame 1 is fixed on the processing table through the positioning seat 20 and the positioning hole 21;

[0054] According to the size of the PCB board to be processed, the first screw module 2 drives the clamp adjustment seat 6 to move, and the distance between the two clamp adjustment seats 6 is changed by displacement to adjust the distance to adapt to the length range of the PCB board;

[0055] The second lead screw module 10 drives the clamping assembly 11 to move, and the spacing between the clamping assemblies 11 at the same end is adjusted to adapt to the width range of the PCB board;

[0056] The PCB board is placed on the anti-skid rubber table 12 in the adjusted position, and the flip frame 14 is driven by the motor to flip downward, and the pressing plate 15 is pressed down to limit the placed PCB board. During the pressing, the pressure sensor 17 detects the pressure change and feeds back the signal to the controller. After reaching the required pressure range, the controller stops the flipping movement of the motor, so that the PCB board is confined between the pressing plate 15 and the anti-skid rubber table 12;

[0057] When taking the PCB, the motor drives the flip frame 14 to flip upward, so that the PCB is no longer restricted, and the user can take the PCB at that location.

[0058] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
