DETAILED DESCRIPTION

[0017] 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.

[0018] Reference Figure 1-Figure 3 , a PCBA board feeding device, including an annular conveying device 1, the annular conveying device 1 is a prior art, and a device for unloading is provided at one place of the annular conveying device 1, a plurality of placing devices 2 are fixedly connected to the top of the annular conveying device 1, each placing device 2 includes a fixed plate 3 arranged above the annular conveying device 1, a support plate 4 is fixedly connected to the bottom wall of each fixed plate 3, and the bottom end of each support plate 4 is fixedly connected to the top of the annular conveying device 1, and a connecting groove 9 is opened on the left and right side walls of each fixed plate 3, and each connecting groove 9 is arranged through the fixed plate 3, and a clamping plate 10 is slidably connected between the front and rear inner walls of each connecting groove 9, and the upper and lower ends of the clamping plate 10 pass through the connecting groove 9 and extend to the outside of the connecting groove 9, and an adjusting structure is provided on the fixed plate 3, and a plurality of PCBA boards are arranged on the fixed plate 3, and the weight of the PCBA board causes the adjusting structure to adjust the clamping plate 10, so that the clamping plate 10 moves to clamp the two sides of the PCBA board, thereby fixing it;

[0019] The adjustment structure includes a placement plate 5 arranged above the fixed plate 3, the bottom end of the placement plate 5 is fixedly connected to a fixing rod 6, each fixing rod 6 penetrates the fixed plate 3 and extends to the bottom of the fixed plate 3, and the bottom end of the fixing rod 6 is fixedly connected to a connecting plate 7, the bottom end of each clamping plate 10 and the side wall of the connecting plate 7 are provided with a corresponding adjustment groove 11, and each adjustment groove 11 penetrates the corresponding connecting plate 7 and the clamping plate 10 respectively, and an adjustment shaft 12 is fixedly connected between the front and rear inner walls of each adjustment groove 11, and the corresponding adjustment shaft 12 An adjusting plate 13 is arranged between the two adjusting plates 13, and the two ends of each adjusting plate 13 are respectively rotatably sleeved on the corresponding adjusting shaft 12. When the PCBA board is placed on the placing plate 5, the weight of the PCBA board causes the placing plate 5 to move downward, driving the fixing rod 6 and the connecting plate 7 to move downward accordingly. When the connecting plate 7 moves downward, the adjusting shafts 12 arranged on both sides of the connecting plate 7 move downward together, thereby pulling the corresponding adjusting plate 13 to move. When the adjusting plate 13 moves, it pulls the clamping plate 10 to move in the direction of the PCBA board, and fixes and clamps the PCBA board.

[0020] The outer side of each fixing rod 6 located above the fixing plate 3 is sleeved with a connecting spring 8, the bottom end of each connecting spring 8 is fixedly connected to the top of the fixing plate 3, and the bottom end of each connecting spring 8 is fixedly connected to the top of the placement plate 5. When the placement plate 5 moves downward, the connecting spring 8 will contract, thereby buffering the pressure of the PCBA board to prevent the placement plate 5 from descending too fast, causing the clamping plate 10 to collide with the PCBA board and cause damage to it; the outer side of the placement plate 5 is wrapped with a smooth protective layer, and the protective layer is made of soft material to protect the PCBA board from damage;

[0021] A sliding block 14 is fixedly connected to the side wall of each clamping plate 10 located on the inner side of the connecting groove 9, and a sliding groove 15 corresponding to the sliding block 14 is opened on the inner side wall of each connecting groove 9 to facilitate the movement of the clamping plate 10; a groove is provided on the side wall of each clamping plate 10 close to the inner side of the fixed plate 3, and the groove is vertically arranged. The vertical groove can prevent the PCBA board from sliding off the placement plate 5, and can also prevent the PCBA board from causing obstruction to it.

[0022] In the utility model, when the device is in use, the PCBA board is first placed on the placement plate 5, and the weight of the PCBA board causes the placement plate 5 to move downward, driving the fixing rod 6 and the connecting plate 7 to move downward accordingly. When the connecting plate 7 moves downward, the adjusting shafts 12 arranged on both sides of the connecting plate 7 move downward together, thereby pulling the corresponding adjusting plate 13 to move. When the adjusting plate 13 moves, it pulls the clamping plate 10 to move in the direction of the PCBA board to fix and clamp the PCBA board. At the same time, when the placement plate 5 moves downward, the connecting spring 8 will contract, thereby buffering the pressure of the PCBA board to prevent the placement plate 5 from descending too fast, causing the clamping plate 10 to collide with the PCBA board and damage it. Then, the annular conveying device 1 is started to rotate, and the annular conveying device 1 drives the placement structure 2 to rotate together, so that the placement device 2 and the PCBA board are moved together to the unloading location for unloading processing.
