Description

Technical Field

[0001] This utility model belongs to the field of electronic manufacturing technology and relates to a feeding device for a motherboard chip mounter. Background Technology

[0002] In modern electronics manufacturing, pick-and-place machines play an indispensable role as a crucial component of automated production equipment. As electronic products become increasingly complex and integrated, higher demands are placed on the assembly precision and speed of components on motherboards. To meet these needs, the design of pick-and-place machines is constantly evolving to adapt to rapidly changing technical standards and production efficiency requirements.

[0003] The core function of a pick-and-place machine is to accurately place surface mount devices (SMDs) into designated locations on a printed circuit board (PCB). This process requires a series of sophisticated mechanical and electronic components working together, among which the feeding device is one of the key components ensuring the smooth operation of the entire placement process. The feeding device's task is to provide a continuous and stable supply of components, enabling the placement mechanism to efficiently pick up and mount these components.

[0004] Traditional pick-and-place machines typically use vibratory feeders or track-type feeders to transport various types of electronic components. However, for components of different sizes and shapes, as well as circuit boards of different sizes, the distance and path that the placement mechanism needs to precisely deliver the component to the target location after picking it up from the feeder will vary. In this case, the existing fixed pick-and-place feeder structure becomes inflexible. Because the placement mechanism must frequently travel back and forth between the fixed feed structure to pick up the required component, this not only increases operation time but also reduces overall work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a feeding device for a motherboard chip mounter that can automatically follow the movement of the mounting mechanism without changing other structures, enabling the mounting mechanism to pick up components more quickly, shortening operation time, and improving overall operation efficiency.

[0006] To solve the above technical problems, this utility model provides a feeding device for a motherboard chip mounter, including a mounting plate. A longitudinal linear motor is provided at the upper end of the mounting plate. The longitudinal linear motor includes a longitudinal magnetic rail and a longitudinal mover that slides along the longitudinal magnetic rail. The upper end of the longitudinal mover is connected to a transverse linear motor. The transverse linear motor includes a transverse magnetic rail that is perpendicular to the longitudinal magnetic rail and connected to the upper end of the longitudinal mover, and a transverse mover that slides along the transverse magnetic rail. The upper end of the transverse mover is connected to a feeding rack.

[0007] Multiple external rotor motors are installed side-by-side at the lower end of one end of the transverse magnetic rail inside the feeding rack. Above the external rotor motors, a horizontal mounting shaft parallel to the longitudinal magnetic rail is connected to the feeding rack for mounting the material roll. An opening is provided on one side of the feeding rack at the corresponding position of the external rotor motor and the horizontal mounting shaft. An end guide shaft parallel to the longitudinal magnetic rail is connected above the end of the feeding rack away from the horizontal mounting shaft. The end guide shaft is located above the horizontal mounting shaft. A middle guide shaft located above the horizontal mounting shaft and below the end guide shaft is connected in the middle of the feeding rack.

[0008] By adopting the above technical solution, the strip rolls are installed one by one on the horizontal mounting shaft. A winding pulley is fitted over each outer rotor motor. The head end of the strip is wound around the end guide shaft and the middle guide shaft and onto the winding pulley. During component placement, the longitudinal linear motor and the transverse linear motor cooperate to ensure that the end guide shaft is always close to the component placement mechanism and follows its movement. After each component placement is completed, the component placement mechanism only needs to return to the upper part of the feeder via the extreme path. The rotation of the outer rotor motor drives the winding pulley to rotate and wind the strip, causing the strip at the corresponding position to move continuously to supply components to the component placement mechanism, shortening the component pick-up time and improving overall efficiency.

[0009] The present invention is further configured such that the mounting plate is provided with slide rails at both ends of the transverse magnetic rail, which are arranged along the length direction, and that slide bars are provided at both ends of the transverse magnetic rail, which are slidably connected to the corresponding slide rails.

[0010] The present invention is further configured such that the horizontal mounting shaft is fitted with a plurality of connecting collars that correspond one-to-one with and are rotatably connected to the external rotor motor, and the outer periphery of the connecting collars is provided with friction texture.

[0011] The present invention is further configured such that the end guide shaft is fitted with a plurality of end guide collars that correspond one-to-one with and are rotatably connected to the external rotor motor, and the outer periphery of each end guide collar is recessed inward to form a groove.

[0012] The present invention is further configured such that the central guide shaft is fitted with a plurality of central guide collars that correspond one-to-one with and are rotatably connected to the external rotor motor, and the outer periphery of each central guide collar is recessed inward to form a groove.

[0013] The present invention is further configured such that a traction guide shaft at the same height as the end guide shaft is connected to the middle part of the feeding rack near the horizontal mounting shaft.

[0014] The present invention is further configured such that the traction guide shaft is fitted with a plurality of traction collars that correspond one-to-one with and are rotatably connected to the outer rotor motor, and the outer periphery of each traction collar is recessed inward to form a groove.

[0015] Compared with the prior art, the present invention has the following advantages: The present invention uses a longitudinal linear motor and a transverse linear motor to enable the end guide shaft to always be close to the placement mechanism and follow its movement. The placement mechanism only needs to return to the pole segment path to complete the rapid picking of components, effectively shortening the component picking time and improving the overall operation efficiency.

The same or similar reference numerals in the drawings represent the same or similar parts.

[0021] Example, refer to Figure 1-3 A feeding device for a motherboard chip mounter includes a mounting plate 1. A longitudinal linear motor is mounted on the upper end of the mounting plate 1. The longitudinal linear motor includes a longitudinal magnetic rail 2 and a longitudinal mover 3 that slides along the longitudinal magnetic rail 2. A transverse linear motor is connected to the upper end of the longitudinal mover 3. The transverse linear motor includes a transverse magnetic rail 4 that is perpendicular to the longitudinal magnetic rail 2 and connected to the upper end of the longitudinal mover 3, and a transverse mover 5 that slides along the transverse magnetic rail 4. A slide rail 6 is provided at both ends of the transverse magnetic rail 4 along its length. A slide bar 7 is provided at both ends of the transverse magnetic rail 4 and slidably connected to the corresponding slide rail 6. A feeding rack 8 is connected to the upper end of the transverse mover 5. The feeding rack 8 is driven to move arbitrarily with the chip mounter mechanism by means of the longitudinal and transverse linear motors.

[0022] Multiple external rotor motors 9 are installed side-by-side at the lower end of one end of the transverse magnetic rail 4 inside the feeding rack 8. Each external rotor motor 9 is covered by a belt reel. Above the external rotor motors 9 inside the feeding rack 8, there is a horizontal mounting shaft 10 parallel to the longitudinal magnetic rail 2 for mounting the material strip roll. The horizontal mounting shaft 10 is covered by multiple connecting collars 11 that correspond one-to-one with the external rotor motors 9 and are rotatably connected to them. The outer circumference of the connecting collars 11 is provided with friction texture. Each connecting collar 11 is covered by a roll of material strip. An opening is provided on one side of the feeding rack 8 at the corresponding position of the external rotor motors 9 and the horizontal mounting shaft 10.

[0023] An end guide shaft 12 parallel to the longitudinal magnetic rail 2 is connected above the end of the feed rack 8 away from the horizontal mounting shaft 10. The end guide shaft 12 is located above the horizontal mounting shaft 10, and one end of the feed rack 8 at the end guide shaft 12 is a flat structure that can extend into the placement mechanism and the main board. A middle guide shaft 13 located above the horizontal mounting shaft 10 and below the end guide shaft 12 is connected in the middle of the feed rack 8. A traction guide shaft 14 at the same height as the end guide shaft 12 is connected in the middle of the feed rack 8 near the horizontal mounting shaft 10, so that the material strip can reach the end guide shaft 12 horizontally and can also reach the middle guide shaft 13 horizontally from the end guide shaft 12. The end guide shaft 12 is fitted with multiple end guide collars 15 that correspond one-to-one with and are rotatably connected to the outer rotor motor 9. The middle guide shaft 13 is fitted with multiple middle guide collars 16 that correspond one-to-one with and are rotatably connected to the outer rotor motor 9. The traction guide shaft 14 is fitted with multiple traction collars 17 that correspond one-to-one with and are rotatably connected to the outer rotor motor 9. The outer periphery of each end guide collar 15, each middle guide shaft 13 and each traction collar 17 is recessed inward to form a groove, which makes it easier for the material belt to pass through one by one.

[0024] Working principle: The strip rolls are installed one by one on the connecting collar 11 of the horizontal mounting shaft 10. A winding pulley is sleeved on each outer rotor motor 9. The head end of the strip is wound around the end guide shaft 12 and the middle guide shaft 13 and wound onto the winding pulley. During the placement process, the longitudinal linear motor and the transverse linear motor cooperate to ensure that the end guide shaft 12 is always close to the placement mechanism and follows its movement. After each placement, the placement mechanism only needs to return to the upper part of the feeder 8. The rotation of the outer rotor motor 9 drives the winding pulley to rotate, winding the strip and moving the strip at the corresponding position to continuously supply components to the placement mechanism, shortening the component pick-up time and improving overall efficiency.
