[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-5 In this embodiment of the utility model, a conveying fixture for circuit board processing includes a first support 1 and a second support 5. A guide slide rod 2 is fixedly installed between the two vertical plates of the first support 1. Two symmetrically arranged sliding frames 3 are slidably installed on the outer wall of the guide slide rod 2. A conveying mechanism is installed on the top of the sliding frame 3. A driving mechanism extending to one end of the first support 1 is installed at the bottom end of the sliding frame 3. A first guide rail 4 is slidably installed between the two second supports 5 at one end of the first support 1. A guide mechanism for the driving mechanism to slide along the length direction of the first support 1 is installed at one end of the first guide rail 4. An adjustment mechanism connected to the inner side of the vertical plate of the two sliding frames 3 is installed on the top of the bottom plate of the first support 1.

[0020] In this embodiment: First, the adjustment mechanism is activated according to the size of the PCB board to be mounted. The adjustment mechanism pushes the two sliding frames 3 to move in opposite directions along the outer wall of the guide slide rod 2. The two sliding frames 3 drive the conveying mechanism at their top to move synchronously until the distance between the inner sides of the two conveying mechanisms is equal to the width or length of the PCB board to be mounted. At this time, the guide mechanism is in a state of releasing the limit on the drive mechanism. After the adjustment is completed, the guide mechanism is rotated, and the guide mechanism limits the drive mechanism again. Then, by activating the drive mechanism, the drive mechanism drives the conveying mechanism to perform transmission. At this time, the PCB board can be placed between the two conveying mechanisms, realizing the adjustment of the PCB board by the conveying mechanism and conveying the PCB board to the position of the pick-and-place machine.

[0021] Please refer to this carefully. Figure 2The adjustment mechanism includes an electric push cylinder 9 fixedly installed on the top of the base plate of the first bracket 1. A connector 10 is fixedly installed at the output end of the electric push cylinder 9. A rotating arm 11 is rotatably connected to the fixed ear of the connector 10. A connecting ear 12 is rotatably installed on the top of the rotating arm 11. The connecting ear 12 is fixedly connected to the inner side of the vertical plate of the sliding frame 3.

[0022] In this embodiment: by activating the electric push cylinder 9, the electric push cylinder 9 drives the connecting member 10 to move upward or downward. At this time, the bottom end of the rotating arm 11 moves downward as the connecting member 10 moves upward or downward. The top end of the rotating arm 11 pulls the sliding frame 3 to move through the connecting ear 12. At this time, the two sliding frames 3 move towards each other along the guide slide rod 2. The top end of the rotating arm 11 moves upward. The top end of the rotating arm 11 pushes the sliding frame 3 to move through the connecting ear 12. At this time, the two sliding frames 3 move in opposite directions along the guide slide rod 2, so as to realize that the sliding frame 3 drives the conveying mechanism to move, so as to adjust the distance between the two conveying mechanisms.

[0023] Please refer to this carefully. Figure 1 and Figure 2 The conveying mechanism includes drive rollers 6 rotatably mounted above both ends of the top plate of the sliding frame 3. The two drive rollers 6 are connected by a drive belt 7. The top plate of the sliding frame 3 is rotatably mounted between the two drive rollers 6. The limit rollers 8 are used to limit the inward deformation of the drive belt 7. The outer periphery of the drive belt 7 is formed with outward protruding clamping blocks.

[0024] In this embodiment: After the conveying mechanism and the driving mechanism are adjusted, the driving mechanism is started, and the driving mechanism drives the connected transmission roller 6 to rotate. The transmission roller 6 drives another transmission roller 6 to rotate synchronously through the transmission belt 7. At this time, the transmission belt 7 is in motion, and the two ends of the PCB board can be placed between the clamping blocks. The transmission belt 7 can then drive the PCB board to be conveyed. The design of the limiting roller 8 can prevent the transmission belt 7 from deforming during the conveying process.

[0025] Please refer to this carefully. Figure 3 , Figure 4 and Figure 5 The guiding mechanism includes a second guide rail 13 fixedly installed at one end of the first guide rail 4. A slider is slidably connected to the inner wall of the second guide rail 13. A support frame 14 is fixedly connected to the top of the slider. The vertical cross section of the support frame 14 is in the shape of an "I". The bottom plate of the support frame 14 has a downward protruding limiting ear 22 integrally formed at the bottom. The bottom end of the first guide rail 4 has a downward protruding support ear 21 integrally formed. A limiting screw 20 is threadedly connected to the inner wall of the support ear 21. One end of the limiting screw 20 abuts against the limiting ear 22.

[0026] In this embodiment: when adjusting the distance between the two conveying mechanisms through the adjustment mechanism, the limiting screw 20 is rotated first. At this time, the limiting screw 20 rotates outward and no longer limits the drive mechanism. During the adjustment process, the drive mechanism slides along the second guide rail 13. After the adjustment is completed, the limiting screw 20 is rotated again and rotated inward until one end of the limiting screw 20 abuts against the limiting ear 22. At this time, the drive mechanism cannot move, ensuring the stability of the drive mechanism during operation.

[0027] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The drive mechanism includes two gears 16 rotatably mounted on the top of the support frame 14. The two gears 16 mesh with each other. A first pulley 17 is coaxially fixedly mounted on the top of the gears 16. The first pulley 17 is connected to a second pulley 19 via a connecting belt 18. The second pulley 19 is coaxially connected to the bottom end of the transmission roller 6 via a rotating shaft. The rotating shaft is rotatably connected to the sliding frame 3 via a bearing. A rotary motor 15 is mounted on the bottom plate of the support frame 14. The output shaft of the rotary motor 15 is coaxially fixedly connected to the bottom end of one of the gears 16.

[0028] In this embodiment: after the conveying mechanism is adjusted and positioned, the rotary motor 15 is started, and the rotary motor 15 drives the connected gear 16 to rotate. The gear 16 drives another gear 16 to rotate synchronously in the opposite direction. The two gears 16 drive the two first pulleys 17 to rotate synchronously in the opposite direction. The two first pulleys 17 drive the second pulley 19 to rotate through the connecting belt 18. At this time, the two second pulleys 19 rotate synchronously and in the opposite direction, realizing that the two transmission rollers 6 rotate synchronously and in the opposite direction, and realizing that the two transmission belts 7 transmit in opposite directions, thus achieving the clamping and conveying effect.

[0029] Please refer to this carefully. Figure 4 The sliding frame 3 has an integrally formed guide block protruding outward at one end near the first guide rail 4. The guide block is slidably connected to the inner wall of the first guide rail 4.

[0030] In this embodiment: during the movement of the two sliding frames 3, the sliding frame 3 drives the guide block to slide on the inner wall of the first guide rail 4.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
