[0046] Among them, in order to achieve the purpose of clamping and fixing, the present device adopts the following technical scheme: four boxes 20 are fixedly connected to the top of the bottom plate 2, and the inner sides of the four boxes 20 are each provided with a through groove 1, and the insides of the four boxes 20 are each slidably provided with a piston 21, and the bottoms of the two bidirectional screws 7 are each provided with a clamping plate 22, and the two clamping plates 22 are in sliding contact with the top of the bottom plate 2, and two moving rods 23 are fixedly connected to the two clamping plates 22, and the outer ends of the four moving rods 23 are respectively fixedly connected to the inner sides of the four pistons 21, and the four moving rods 23 respectively penetrate the four through grooves and are in sliding contact with them, and the bottom of the bottom plate 2 is fixedly connected to two boxes 24, and the inner sides of the two boxes 24 are each provided with a through groove 2, and the insides of the two boxes 24 are each slidably provided with a piston 25, and the inner sides of the two pistons 25 are each fixedly connected with a rope 26, and the ends of the two ropes 26 are fixedly connected to the front side of the threaded block 11 , two ropes 26 respectively pass through the two through slots 2, two connecting rods 27 are fixedly connected to the bottom of the bottom plate 2, the two ropes 26 are respectively in sliding contact with the two connecting rods 27, the two ropes 26 are both sleeved with springs 28 on the outside, and the two ends of the springs 28 are respectively fixedly connected to the piston and the inner wall of the box body 24, and the two boxes 24 are both fixedly embedded with pipes 1 29, and the two pipes 1 29 both pass through the bottom plate 2 and are fixedly connected thereto, and the two pipes 1 29 are both fixedly embedded with two pipes 2 30, and the ends of the four pipes 2 30 are respectively fixedly embedded on the outside of the four boxes 1 20, and the box body 1 20, the box body 24, the piston 1 21, the piston 25, the card plate 22 and other components are designed. When the glue is poured, the two card plates 22 can clamp and fix the shell 31, so that the stability of the shell 31 can be guaranteed when the glue is poured into the shell 31 through the holes and grooves on the PCB circuit board 32;

[0047] In order to reduce wear, the device is implemented by the following technical solution: the bidirectional screw 7 is connected to the support plate 3 through a bearing, and the threaded rod 10 is connected to the bottom shell 1 through a bearing. The bearing connection can reduce wear.

[0048] The use process of the present invention is as follows: when it is necessary to perform glue pouring, the motor 9 is controlled to work to rotate the threaded rod 10, the threaded rod 10 rotates to drive the chain 15 to rotate, the chain 15 rotates to drive the right-side bidirectional screw 7 to rotate, the right-side bidirectional screw 7 rotates to drive the chain 2 18 to rotate, and the chain 2 18 rotates to drive the left-side bidirectional screw 7 to rotate, so that the two bidirectional screws 7 can be rotated. Since the bidirectional screw 7 has two threads with opposite spiral directions, the rotation of the two bidirectional screws 7 can make the four sliders 8 move outward, so that the two blocks 5 and the two rubber rings 6 move outward, so that the distance between the two rubber rings 6 will become larger;

[0049] The threaded rod 10 can also rotate to move the threaded block 11 backward, so that the two ropes 26 can be pulled, and then the two pistons 25 can be moved toward the middle under the action of the two ropes 26. At the same time, the two springs 28 are compressed. When the two pistons 25 move toward the middle under the action of the two pipes 1 29 and the four pipes 2 30, the air in the four boxes 1 20 will be sucked into the two boxes 1 20, so that the four pistons 1 21 can move outward, and then the distance between the two clamping plates 22 can be increased under the action of the four moving rods 1 23;

[0050] When the distance between the two rubber rings 6 and the distance between the two card plates 22 become larger, the housing 31 is placed between the four positioning blocks 4, and then the PCB circuit board 32 is placed in the housing 31. Then, the motor 9 is controlled to reverse to reverse the threaded rod 10, and then the two bidirectional screws 7 are reversed, so that the four sliders 8 will move toward the middle, and then the two card blocks 5 will move toward the middle, so that the two rubber rings 6 can be wrapped around the outside of the housing 31, and then the slots on the housing 31 can be wrapped, and then the housing 31 can be filled with glue through the holes on the PCB circuit board 32. Since the two rubber rings 6 wrap the housing 31, the colloid can be prevented from overflowing when the glue is poured, which can not only avoid the waste of colloid but also ensure the quality of packaging;

[0051] When the threaded rod 10 is reversed, the threaded block 11 will move forward, so that the pulling force on the two pistons 25 can be released, and then the air in the two boxes 24 will return to the four boxes 1 20 under the rebound effect of the two springs 28, so that the four pistons 1 21, the four moving rods 1 23 and the two clamping plates 22 will move toward the middle, so that the two clamping plates 22 can clamp and fix the shell 31, so that when the glue is poured into the shell 31 through the holes on the PCB circuit board 32, the stability of the shell 31 can be guaranteed, and then the glue pouring work can be guaranteed to proceed normally;

[0052] After the glue filling is completed, the motor 9 is controlled to work so that the distance between the two rubber rings 6 becomes larger, and the housing 31 and the PCB circuit board 32 after the glue filling are removed.

[0053] The above are only preferred embodiments of the present invention. Any person skilled in the art may modify the present invention by using the above technical solutions or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solution of the present invention belongs to the scope of protection claimed by the present invention.
