These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0029] Combined with appendix Figure 1 and attached Figure 2As shown, an automatic assembly machine for catheter sheaths and sheath seats includes a horizontal conveying mechanism 1, a fixture 2, a fixture opening mechanism 3, a catheter sheath guide plate 4, a catheter reaming mechanism 5, a sheath seat pushing mechanism 6, a catheter sheath discharging mechanism 7, and a sheath seat discharging mechanism 8. The fixture 2 is connected to the horizontal conveying mechanism 1. The catheter sheath discharging mechanism 7 is located above the horizontal conveying mechanism 1. The catheter reaming mechanism 5 and the sheath seat pushing mechanism 6 are sequentially arranged on one side of the horizontal conveying mechanism 1. The two fixture opening mechanisms 3 are located on opposite sides of the horizontal conveying mechanism 1. The catheter sheath guide plate 4 is installed on the fixture opening mechanism 3. The sheath seat discharging mechanism 8 is located above the sheath seat pushing mechanism 6. The other two opposite fixture opening mechanisms 3 are located below the working platform.

[0030] The horizontal conveying mechanism 1 includes a straight rail 11, a chain 12, a sprocket, and a motor. Two parallel straight rails 11 are fixed to the upper and lower ends of the working platform, respectively. The chain 12 passes through the two straight rails 11. Sprockets are rotatably connected to both ends of the straight rails 11. One of the sprockets is fixed to the output shaft of the motor. Both sprockets are meshed on the chain 12. The fixture 2 is slidably connected to the straight rails 11 and is connected to the chain 12.

[0031] The motor drives the sprocket to rotate, which in turn drives the chain 12 to rotate on the two straight rails 11. The chain 12 then pulls the fixture 2 to rotate back and forth along the two straight rails 11.

[0032] As attached Figure 5 As shown, the fixture 2 includes a base plate 21, a clamping plate 22, a groove 23, and a spring. Two clamping plates 22 are slidably connected to the base plate 21. A spring connects the clamping plate 22 to the base plate 21. A groove 23 is provided at the end of the clamping plate 22, and an inclined surface is provided on the groove 23.

[0033] The fixture opening mechanism 3 includes a horizontal slide cylinder 31 and rollers 32. Two rollers 32 are rotatably connected to the slide of the horizontal slide cylinder 31 for extending into the grooves 23 of the clamping plate 22.

[0034] The guide plate 4 of the catheter sheath is a curved plate, which is fixed on the slide of the horizontal slide cylinder 31.

[0035] Initially, the two clamping plates 22 of fixture 2 are held together by the spring pressure. When fixture 2 moves between the two fixture 2 opening mechanisms 3, the horizontal slide cylinder 31 drives the roller 32 to move horizontally towards the groove 23. As the roller 32 inserts into the groove 23, it first contacts the inclined surface of the groove 23, thus pushing the two clamping plates 22 outwards horizontally. At this time, the spring is compressed, allowing fixture 2 to open. Because the left and right catheter sheath guide plates 4 are symmetrical curved plates in an inverted V-shape, when the catheter sheath falls downwards into fixture 2, it will move to the precise set position within fixture 2 under the limiting and guiding action of the two catheter sheath guide plates 4.

[0036] After the roller 32 retracts and resets, the two clamps 22 will clamp the middle catheter sheath under the spring's return force.

[0037] The catheter reamer mechanism 5 includes a horizontal slide cylinder three and a tapered rod. The tapered rod for enlarging the catheter sheath opening is fixed on the slide of the horizontal slide cylinder three. The horizontal slide cylinder three can drive the tapered rod to move horizontally in a linear fashion.

[0038] As attached Figure 4 As shown, the sheath seat pushing mechanism 6 includes a base block 61, a rotating column 62, a second motor 63, a feed hole 64, a through hole 65, a push rod 66, and a horizontal slide cylinder 67. The base block 61 is fixed on the working platform, the rotating column 62 is rotatably connected inside the base block 61, the output shaft of the second motor 63 is connected to the rotating column 62, and the push rod 66 for pushing the sheath seat is fixed on the slide of the horizontal slide cylinder 67. The base block 61 is provided with a feed hole 64 for accommodating the sheath seat and a through hole 65 for passing through the push rod 66. The rotating column 62 is provided with a through hole for passing through the sheath seat.

[0039] In the initial state, the feed hole 64 of the base block 61 is aligned with the discharge port of the upper discharge pipe 86, and the through hole on the rotating column 62 is connected to the feed hole 64. After the sheath seat falls into the base block 61 through the discharge pipe 86, it will directly enter the through hole of the rotating column 62. Then, the rotating column 62 rotates 90 degrees, so that the through hole of the rotating column 62 is connected to the horizontal through hole 65 of the base block 61. Finally, the horizontal slide cylinder 67 drives the push rod 66 to move horizontally, and the push rod 66 pushes the sheath seat in the rotating column 62 horizontally out and inserts it into the guide sheath on the opposite fixture 2.

[0040] The duct sheath discharge mechanism 7 includes a hopper 71, a rotating cylinder 72, and a motor 73. The rotating cylinder 72 is rotatably connected to the opening at the bottom of the hopper 71. The rotating cylinder 72 is fixed on the output shaft of the motor 73. Several strip-shaped grooves for accommodating the duct sheath are distributed on the rotating cylinder 72.

[0041] After the guide sheath enters the hopper 71, it slides along the inclined flow channel of the hopper 71 towards the rotating drum 72. Motor 3 73 drives the rotating drum 72 to rotate. As the guide sheath moves to the rotating drum 72, it enters one by one into the strip-shaped groove on the drum 72. When the strip-shaped groove carrying the guide sheath rotates to below the working platform, the guide sheath falls into the box below.

[0042] As attached Figure 3 As shown, the sheath seat discharge mechanism 8 includes a vibratory plate 81, a base 82, a turntable 83, a receiving groove 84, a discharge port 85, a discharge pipe 86, and a motor 4. The discharge port of the vibratory plate 81 is located above the base 82. The base 82 is provided with a circular groove. The turntable 83 is rotatably connected in the circular groove and is fixed on the output shaft of the motor 4. The edge of the turntable 83 is provided with a receiving groove 84 for accommodating the sheath seat. The circular groove is provided with a discharge port 85, which communicates with the discharge pipe 86. The discharge pipe 86 is located above the base block 61.

[0043] In the initial state, the receiving groove 84 of the turntable 83 is aligned with the discharge port of the vibrating plate 81. After the vibrating plate 81 transmits a sheath seat to the receiving groove 84, the motor four-wheel drive causes the turntable 83 to rotate until the receiving groove 84 rotates to be directly above the discharge port in the circular groove. In this way, the sheath seat in the receiving groove 84 will fall into the discharge pipe 86 below through the discharge port.

[0044] Several guide wheels for cooperating with the horizontal conveying mechanism 1 are rotatably connected to the base plate 21.

[0045] The working method of this application is as follows: First, the horizontal conveying mechanism 1 drives the fixture 2 to move below the catheter sheath discharge mechanism 7. At this time, the fixture opening mechanisms 3 on both sides of the fixture 2 open the fixture 2. After the horizontal conveying mechanism 1 drops a catheter sheath into the fixture 2, the fixture opening mechanism 3 retracts from the fixture 2, so that the fixture 2 clamps the catheter sheath. Next, the fixture 2 moves to the side of the catheter reaming mechanism 5. The horizontal slide cylinder drives the conical rod to be inserted horizontally into the opening of the catheter sheath, widening the opening of the catheter sheath to facilitate the installation of the sheath seat. Then, the fixture 2 is moved to the side of the sheath seat pushing mechanism 6. The sheath seat discharge mechanism 8 drops a sheath seat into the sheath seat pushing mechanism 6. The sheath seat pushing mechanism 6 then pushes the sheath seat horizontally and inserts it into the opening of the catheter sheath, completing the assembly of the catheter sheath and the sheath seat. Finally, the fixture 2 is conveyed between the two fixture opening mechanisms 3 below the worktable. The fixture opening mechanisms 3 open the downward-facing fixture 2, and the finished catheter sheath inside the fixture 2 falls into the box below.

[0046] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
