Description

Technical Field

[0001] This utility model belongs to the field of insertion machine technology, specifically a quick width adjustment and locking structure for insertion machine guide rails. Background Technology

[0002] An insertion machine is a mechanical device that automatically and standardly inserts regular electronic components into the conductive vias of a printed circuit board. The insertion machine needs to be equipped with two guide rails for mounting the circuit board. Through an internal chain drive mechanism, the circuit board can be moved along the guide rails to achieve continuous operation. However, the width of the guide rails in existing insertion machines is usually not adjustable. A single insertion machine can only accommodate circuit boards that match its size for support and guidance, resulting in poor flexibility. Therefore, this application proposes a quick-width adjustment and locking structure for the guide rails of the insertion machine. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Depend on Figures 1 to 4 The present invention discloses a quick-width adjustment and locking structure for a guide rail of a plug-in machine, comprising a first guide rail 1, a second guide rail 2, a width adjustment mechanism 3, and a locking mechanism 4. The width adjustment mechanism 3 and the second guide rail 2 are both fixedly mounted on the plug-in machine. The first guide rail 1 is mounted on the width adjustment mechanism 3. The locking mechanism 4 connects the second guide rail 2 and the plug-in machine. Movable support seats 13 are fixedly installed at both ends of the bottom of the first guide rail 1. A controller 26 is installed on the width adjustment mechanism 3. The width adjustment mechanism 3 consists of a support platform 5, two supports 6, a dual-axis servo motor 7, two drive shafts 8, two bevel gears 9, two screws 10, two limit rods 11, and two bevel gears 12. The support platform 5 and the supports 6 are fixedly connected to the plug-in machine. The dual-axis servo motor 7 is fixedly connected to... At the top center of the support platform 5, two drive shafts 8 are fixedly connected to the output shafts at both ends of the dual-axis servo motor 7, two bevel gears 9 are fixedly connected to the ends of the two drive shafts 8 away from the dual-axis servo motor 7, two screws 10 are rotatably connected between the second guide rail 2 and the support 6 through bearings, two limit rods 11 are fixedly connected between the second guide rail 2 and the support 6, two bevel gears 12 are fixedly connected to one end of the two screws 10 and mesh with the bevel gears 9, a movable support seat 13 is sleeved on the screws 10 and threadedly connected to the screws 10, and the movable support seat 13 is sleeved on the limit rods 11 and slidably connected to the limit rods 11. The spiral directions of the threads on the two screws 10 are opposite, and a protective shell 22 is provided at the top of the support platform 5.

[0022] During width adjustment, the dual-axis servo motor 7 drives the two drive shafts 8 to rotate synchronously. The two drive shafts 8 drive the two bevel gears 9 to rotate, the two bevel gears 9 drive the two bevel gears 12 to rotate, and the two bevel gears 12 drive the two screws 10 to rotate synchronously. At this time, the two screws 10 rotate in opposite directions. By setting the spiral direction of the threads on the two screws 10 to be opposite, the two movable support seats 13 can be driven to move in the same direction. The movable support seats 13 drive the first guide rail 1 to move, thereby realizing width adjustment. The limit rod 11 can play a limiting role.

[0023] The locking mechanism 4 consists of a hydraulic driver 14, two hydraulic pipes 15, and two locking components 16. The hydraulic driver 14 is mounted on the insertion machine. The two locking components 16 are fixedly connected to two movable support seats 13 respectively. The locking components 16 consist of a hydraulic sleeve 17, a piston 18, a push rod 19, a friction plate 20, and a spring 21. The hydraulic sleeve 17 is inserted into one end of the movable support seat 13. The piston 18 is slidably connected to the inside of the hydraulic sleeve 17. The push rod 19 is fixedly connected to one end of the piston 18 and slidably inserted into one end of the hydraulic sleeve 17. The friction plate 20 is fixedly connected to the other end of the push rod 19. The spring 21 is sleeved on the push rod 19. A limit ring 23 is fixedly provided inside the hydraulic sleeve 17. A strip groove 24 is provided on one side of the limit rod 11. A friction strip 25 matching the friction plate 20 is embedded inside the strip groove 24.

[0024] After the width adjustment is completed, the hydraulic actuator 14 starts and supplies hydraulic oil into the two hydraulic pipes 15. The hydraulic oil enters the hydraulic sleeve 17 and pushes the piston 18 to move. The piston 18 drives the push rod 19 and the friction plate 20 to move synchronously, so that the friction plate 20 and the friction strip 25 are tightly fitted. The friction force is used to achieve locking and limiting, thereby improving stability. During the width adjustment, the spring 21 can drive the piston 18 to return to its original position, preventing the friction plate 20 from contacting the friction strip 25.

[0025] During operation, a width adjustment mechanism consisting of a support platform, two supports, a dual-axis servo motor, two drive shafts, two bevel gears (first type), two screws, two limit rods, and two bevel gears (second type) can be used to adjust the width between the first and second guide rails. This allows for support and guidance of circuit boards of different widths, improving flexibility in use. Furthermore, a hydraulic actuator, hydraulic pipes, and a locking assembly consisting of a hydraulic sleeve, piston, push rod, friction plate, and spring enable locking and limiting of the first guide rail after width adjustment, further enhancing stability.
