DETAILED DESCRIPTION

[0022] 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.

[0023] Reference Figure 1-Figure 6A mounting clamping mechanism of a placement machine comprises a mounting base 1, vertical guide rails 2 are fixedly mounted on both ends of the top of the mounting base 1, vertical sliders 3 are slidably inserted on the surface of the vertical guide rails 2, transverse guide rails 4 are fixedly mounted on the surfaces of the two vertical sliders 3, transverse sliders 5 are slidably inserted on the surface of the transverse guide rails 4, telescopic cylinders 6 are fixedly mounted on the surface of the transverse sliders 5, a suction nozzle 7 is fixedly mounted on the telescopic bottom end of the telescopic cylinder 6, a clamping and placing seat 8 is fixedly mounted on the top center of the mounting base 1, and a vertical clamping adjustment device 9 and a transverse clamping adjustment device 10 are respectively arranged inside the clamping and placing seat 8.

[0024] In order to realize the vertical clamping and adjustment of the PCB circuit board, a vertical clamping and adjustment device 9 is set, which includes a placement groove 91 opened on the top of the clamping placement seat 8, and vertical slide grooves 92 are opened on the inner walls at both ends of the placement groove 91. A vertical adjustment groove 93 is opened on the top of the vertical slide groove 92, and the vertical slide groove 92 is fixedly connected to the vertical adjustment groove 93.

[0025] Specifically implemented in this way, through the cooperation of the vertical slide groove 92 and the vertical adjustment groove 93, the PCB circuit board can be accurately adjusted in the vertical direction to ensure the correct relative position between the PCB and other components of the placement machine; the design of the vertical adjustment groove 93 allows a larger adjustment range to adapt to PCBs of different sizes, thereby improving the adaptability of the equipment.

[0026] Vertical guide rods 94 are fixedly installed on the inner walls at both ends of the vertical slide groove 92, and a vertical slide seat 95 is slidably inserted into the arc surface of the vertical guide rod 94. The surface of the vertical slide seat 95 is slidably inserted into the inner wall of the vertical slide groove 92, and an adjustment plate 96 is fixedly installed on the top of the vertical slide seat 95. The surface of the adjustment plate 96 is slidably inserted into the inner wall of the vertical adjustment groove 93.

[0027] Specifically implemented in this way, the vertical guide rod 94 provides a precise guiding effect, ensuring that the vertical slide 95 moves smoothly in the slide groove, reducing lateral deviation, and improving the stability and accuracy of adjustment; this structural design can adapt to PCB circuit boards of different sizes, simply by adjusting the position of the vertical slide 95 and the adjustment plate 96.

[0028] Vertical tension springs 97 are provided at both ends of multiple vertical slides 95, and the inner walls of multiple vertical tension springs 97 are movably connected to the arc surface of the vertical guide rod 94. One end of a vertical tension spring 97 is fixedly installed on the inner wall of the vertical slide groove 92, and the other end of the vertical tension spring 97 is fixedly installed on the surface relative to the vertical slide 95. The two ends of the other two vertical tension springs 97 are fixedly installed on the end faces of the three vertical slides 95 respectively.

[0029] Specifically implemented in this way, the constant pressure provided by the vertical tension spring 97 can ensure that the PCB circuit board is always subjected to uniform pressure during the clamping process, thereby preventing deformation or displacement caused by uneven pressure.

[0030] In order to realize the lateral clamping and adjustment action of the PCB circuit board, a lateral clamping and adjustment device 10 is set, including a lateral connecting rod 101, and the two ends of the lateral connecting rod 101 are respectively fixedly installed on the surfaces of two vertical slides 95, and the front end inner wall of the placement groove 91 and the two ends of multiple lateral connecting rods 101 are provided with lateral slide grooves 102, and the inner walls at both ends of the lateral slide grooves 102 are fixedly installed with lateral guide rods 103, and the circular arc surface of the lateral guide rod 103 is slidably plugged with a lateral slide 104, and the surface of the lateral slide 104 is slidably plugged with the inner wall of the lateral slide groove 102.

[0031] Specifically implemented in this way, through the design of the transverse connecting rod 101 and the slide seat, the PCB circuit board can be easily adjusted in the horizontal direction to meet the clamping requirements of PCBs of different sizes; the transverse slide seat 104 is slidably connected with the circular arc surface of the transverse guide rod 103, which can ensure the stability of the PCB during lateral movement and reduce deviations caused by vibration.

[0032] A transverse tension spring 105 is disposed between every four transverse slides 104 . Both ends of the transverse tension springs 105 are fixedly mounted on the end surfaces of the transverse slides 104 , and the inner walls of the transverse tension springs 105 are movably sleeved on the arc surface of the transverse guide rod 103 .

[0033] Specifically implemented in this way, the transverse tension spring 105 can ensure that the PCB circuit board is subjected to uniform force when it is clamped laterally, preventing the PCB from being deformed or damaged due to uneven force; the constant pressure provided by the transverse tension spring 105 helps to maintain the stability of the PCB circuit board during the clamping process and is not affected by external vibrations.

[0034] A plug-in hole 106 is provided on one side surface of the transverse slide seat 104, and a spring 107 is fixedly installed on the inner bottom wall of the plug-in hole 106. A plug-in rod 108 is fixedly installed on one end of the spring 107. The surface of the plug-in rod 108 is square in shape, and the surface of the plug-in rod 108 is also slidably plugged with the inner wall of the plug-in hole 106. A transverse positioning seat 109 is fixedly installed on the end face of the plug-in rod 108. Positioning grooves 110 are provided on the surfaces of the multiple transverse positioning seats 109, and the inner walls of each four relative positioning grooves 110 are respectively slidably plugged with the four corners of the PCB circuit board.

[0035] Specifically implemented in this way, since the positioning groove 110 on the positioning seat can adapt to PCB corners of different sizes, this design has good adaptability and is suitable for a variety of PCB sizes; in the clamping of the PCB circuit board, the two horizontal positioning seats 109 at one end are kept stationary, and one end of the PCB circuit board is controlled to be placed inside the positioning groove 110, while pushing the two horizontal positioning seats 109 at the other end to slide and controlling the tension spring to stretch to generate tension, thereby controlling the other end of the PCB circuit board to be placed inside the positioning groove 110 on the surface of the two sliding horizontal positioning seats 109, and controlling the clamping and locking of the PCB circuit board by the tension of the tension spring, and at the same time cooperating with the vertical plug-in rod 108 to squeeze the spring 107 to control the vertical squeezing and locking, so as to achieve the horizontal and vertical locking and positioning of the PCB circuit board during installation, and adapt to the clamping of PCB boards of different sizes under the adjusted state, avoiding the effect that the middle PCB circuit board cannot be clamped due to the existing method of using horizontal bar extrusion.

[0036] By setting up the vertical and horizontal clamping adjustment devices 10, the clamping force of the PCB circuit board in the vertical and horizontal directions can be adjusted respectively, ensuring that the entire PCB circuit board is subjected to uniform force during the clamping process, and avoiding positioning problems in the middle due to improper force; through independent vertical and horizontal adjustments, the stability of the PCB circuit board during the patch process can be ensured, and the placement error caused by vibration or tilt can be reduced, avoiding the existing overall cross bar moving clamping positioning in a horizontal tilt, inner concave or outer concave state, resulting in uneven clamping force of the middle PCB circuit board and affecting the accuracy.

[0037] Working principle: When clamping the PCB circuit board, first control the two corners of one end of the first block to be placed on the inner wall of the two positioning grooves 110 on one side, push the adjustment plate 96 to control the vertical tension spring 97 to stretch, and perform vertical clamping adjustment, and then adjust the two horizontal positioning seats 109 at the other end of the PCB circuit board horizontally, and at the same time drive the horizontal tension spring 105 to stretch, and then compress the spring 107 with the plug-in rod 108, and control the positioning grooves 110 on the surface of the four horizontal positioning seats 109 to squeeze and clamp the four corners of the PCB circuit board.

[0038] When the first clamping is completed, the second clamping operation is continued. The second clamping operation only needs to control the two lateral positioning seats 109 at the other end of the PCB circuit board to slide and stretch the lateral tension spring 105, and cooperate with the positioning groove 110 on the surface of the first clamped lateral positioning seat 109 for clamping and positioning, so that multiple PCB circuit boards can be clamped on the surface of the clamping placement seat 8 for patch operation.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
