[0002] The utility model with publication number CN212463918U belongs to the technical field of SMT pick and place machine equipment, specifically relating to a component feeding device for an SMT pick and place machine. It includes a base plate, a support plate on the base plate, a lead screw on the support plate, a first limiting plate on the support plate, two first sliding rods on the two support plates, a sliding plate on the first sliding rod, a reel mounting mechanism on the sliding plate, a support column on the sliding plate, a ball groove on the support column, and balls in the ball groove. A horizontal plate is fixedly connected to the left side of the support column, and a longitudinally arranged second sliding rod is slidably connected to the middle of the horizontal plate. The upper end of the second sliding rod passes through the horizontal plate and has a second limiting plate, while the lower end of the second sliding rod passes through the horizontal plate and has a pressure block. A spring is sleeved on the outside of the second sliding rod, located between the pressure block and the horizontal plate. This feeding device is designed to prevent shaking during use, thus improving operational accuracy and avoiding damage to components caused by large-scale shaking. It also allows for tension adjustment during feeding to prevent breakage of SMT components during the feeding process.

[0003] After searching, it was found that the existing technology has certain defects. It fixes the reel with bolts and nuts, which results in low reel replacement efficiency and is prone to reel jamming, which is not conducive to the rotation and feeding of the reel. Furthermore, the spring elasticity coefficient of the tension adjustment mechanism cannot be adjusted, and it cannot be adapted to the tape feeding of different models and different tension requirements of components. Therefore, a component feeding device for SMT placement machines is needed to meet people's needs. Utility Model Content

[0004] The purpose of this invention is to provide a component feeding device for an SMT pick and place machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a component feeding device for an SMT pick-and-place machine, comprising a support, a transverse moving mechanism, a slide plate, a reel, and a vertical plate. The slide plate has a tapered insertion hole, which is coaxially arranged with a hole on the reel and is fitted with the same insert sleeve. One end of the insert sleeve is open, and the other end is closed. A cylinder is slidably connected to the closed end. A pressure point block is provided at one end of the cylinder outside the insert sleeve, and a tapered column is provided at the other end. Several ball bearings and several roller bearings are embedded in the outer wall of the open end of the insert sleeve. The sides of the beads that are close to each other abut against the inclined surface of the conical column, and the sides that are far apart from each other abut against the inclined surface of the conical insertion hole. A connecting ring is provided on the outer wall of the cylinder located inside the insertion sleeve. A first spring is connected between the connecting ring and the inner wall of the closed end of the insertion sleeve. A pressure ring is provided on the outer wall of the insertion sleeve. The pressure ring is arranged on the side of the reel away from the slide plate. An L-shaped plate is provided on one side of the upright plate. A bolt is internally threaded to the top of the L-shaped plate. A base plate is movably connected to the bottom of the bolt. A second spring is connected to the bottom of the base plate. A pressure plate is connected to the bottom of the second spring.

[0006] Preferably, the inclined surface of the tapered insertion hole is parallel to the inclined surface of the tapered column.

[0007] Preferably, the outer wall of the insert has a plurality of sliding holes, and a plurality of balls are arranged in the corresponding sliding holes. The diameter of the sliding hole on the side closer to the outside of the insert is smaller than the diameter of the ball, and the diameter of the sliding hole on the side closer to the inside of the insert is the same as the diameter of the ball.

[0008] Preferably, the L-shaped plate has a threaded hole, and the threaded section of the bolt is adapted to fit into the threaded hole.

[0009] Preferably, a connecting shaft is rotatably connected to the top of the substrate, the connecting shaft has a T-shaped cross-section, and the bottom end of the bolt is connected to the top of the connecting shaft.

[0010] Preferably, the L-shaped plate has a vertically arranged guide groove on its side end, and both the base plate and the pressure plate have guide blocks on their side ends, with both guide blocks being vertically slidably connected in the guide groove.

[0011] The beneficial effects of this utility model are: This invention employs a quick-locking mechanism consisting of a sleeve, ball bearings, and a conical column. When installing the reel, simply insert the sleeve into the center hole of the reel and the conical insertion hole of the slide plate. Under the action of the first spring, the conical column pushes out the ball bearings and locks them in the conical insertion hole. At the same time, the pressure ring presses the reel to complete the fixation. When disassembling, simply press the finger pressure block to overcome the elastic force of the first spring and cause the conical column to retract, allowing the ball bearings to retract and the sleeve and reel to be easily pulled out. This process requires no tools and can be completed within seconds, greatly improving material changing efficiency.

[0012] In this invention, multiple balls are used for radial locking, resulting in uniform locking force. The pressure ring provides stable axial pressure, avoiding the eccentric force or jamming caused by excessive tightening that may occur with traditional bolt tightening. This ensures the rotational flexibility of the reel during the unloading process.

[0013] In this invention, the pressure of the pressure plate on the tape can be precisely adjusted by rotating the bolt, thereby changing the feeding tension. The operation is simple and intuitive. The most suitable tension can be flexibly set according to the material, width, component weight and other characteristics of different tapes, effectively preventing tape breakage or loosening, and greatly improving the applicability and reliability of the device.

A pressure point 9 is provided at one end of the cylinder 8 outside the insert 7, and a tapered column 10 is provided at the other end. Several ball bearings 11 are embedded in the outer wall of the open end of the insert 7, and the sides of the ball bearings 11 that are close to each other abut against the tapered column 10. On the inclined surface, the sides that are far apart from each other abut against the inclined surface of the conical insertion hole 6. A connecting ring 12 is provided on the outer wall of the cylinder 8 located inside the insertion sleeve 7. A first spring 13 is connected between the connecting ring 12 and the inner wall of the closed end of the insertion sleeve 7. A pressure ring 14 is provided on the outer wall of the insertion sleeve 7. The pressure ring 14 is arranged on the side of the reel 4 away from the slide plate 3. An L-shaped plate 15 is provided on one side of the upright plate 5. A bolt 16 is internally threaded to the top of the L-shaped plate 15. A base plate 17 is movably connected to the bottom end of the bolt 16. A second spring 18 is connected to the bottom end of the base plate 17. A pressure plate 19 is connected to the bottom end of the second spring 18.

[0018] Specifically, in this embodiment, the inclined surface of the conical insertion hole 6 is parallel to the inclined surface of the conical column 10 to ensure that the ball bearing 11 can make uniform contact with both at the same time and be under stable force.

[0019] Specifically, in this embodiment, a number of sliding holes are provided on the outer wall of the sleeve 7, and a number of balls 11 are respectively arranged in the corresponding sliding holes. The diameter of the sliding hole on the side closer to the outside of the sleeve 7 is smaller than the diameter of the ball 11, and the diameter of the sliding hole on the side closer to the inside of the sleeve 7 is the same as the diameter of the ball 11, so as to prevent the ball 11 from falling out and allow the ball 11 to partially retract.

[0020] Specifically, in this embodiment, the L-shaped plate 15 has a threaded hole, and the threaded section of the bolt 16 is adapted to fit into the threaded hole.

[0021] Specifically, in this embodiment, a connecting shaft is rotatably connected to the top of the substrate 17. The cross-section of the connecting shaft is T-shaped. The bottom end of the bolt 16 is connected to the top of the connecting shaft, so that when the bolt 16 rotates, the substrate 17 will not rotate with it, but will only move up and down in a straight line.

[0022] Specifically, in this embodiment, a vertically arranged guide groove is provided on the side end of the L-shaped plate 15, and guide blocks are provided on the side ends of the base plate 17 and the pressure plate 19. The two guide blocks are vertically slidably connected in the guide groove to provide guidance for the movement of the entire tension adjustment mechanism and ensure that its movement is smooth and does not deviate.

[0023] When installing reel 4, simply insert the sleeve 7 into the center hole of reel 4 and the conical insertion hole 6 of slide plate 3. Under the action of the first spring 13, the conical column 10 pushes out the ball 11 and locks it in the conical insertion hole 6. At the same time, the pressure ring 14 presses the reel 4 to complete the fixation. When disassembling, simply press the finger pressure block 9 to overcome the elastic force of the first spring 13 and make the conical column 10 retract, and the ball 11 will retract, so that the sleeve 7 and reel 4 can be easily pulled out. This process does not require any tools and can be completed in a few seconds, which greatly improves the material changing efficiency.

[0024] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto.
