Description

Technical Field

[0001] This application relates to the field of electronic manufacturing technology, and in particular to a multi-channel vibratory parallel ball feeding and dispensing device. Background Technology

[0002] A multi-channel vibratory parallel ball-mounting and dispensing device is a component used to accurately and efficiently distribute solder balls and other solder balls to designated positions, improving ball-mounting efficiency and quality. Early ball-mounting processes often relied on manual operation, with operators manually placing solder balls onto corresponding pads on the chip substrate. This method was extremely inefficient and highly susceptible to human factors, such as operator fatigue and differences in skill level, which could lead to placement errors and inaccurate quantities of solder balls, severely impacting product yield. To address these issues, some ball-mounting equipment has incorporated automation technology, such as multi-channel ball-mounting and dispensing devices, which can control the automatic dispensing of solder balls, thereby improving efficiency and reducing labor costs.

[0003] In the existing technology, although the traditional multi-channel ball feeding device has the ability to convey multiple channels, it suffers from unstable feeding. During the feeding process, the solder balls are easily blocked by mutual compression in the channel, resulting in feeding interruption. Furthermore, it is impossible to effectively control the amount of solder balls fed, often resulting in excessive feeding. Excessive feeding will cause waste of solder balls and affect subsequent processing steps.

[0004] Therefore, we propose a multi-channel vibratory parallel ball feeding and dispensing device to solve the above problems. Utility Model Content

[0022] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0023] See Figure 1 , Figure 2 , Figure 3 and Figure 4This application provides a multi-channel vibratory parallel solder ball feeding and distribution device, including a frame 1 and a solder ball container 2 installed and fixed on the top of the frame 1. The top of the solder ball container 2 is open. Multiple evenly distributed feeding channels 3 are fixedly connected to the right side of the solder ball container 2. The multiple feeding channels 3 are inclined. The bottom inner wall of the solder ball container 2 is inclined. The design of multiple feeding channels 3 can realize multi-channel conveying of solder balls and form multiple solder ball flows for distribution and feeding. The inclined surface setting makes it easier for the solder balls to roll smoothly into the multiple feeding channels 3. The inclined setting of the multiple feeding channels 3 can use the self-weight of the solder balls to assist in the conveying of the solder balls and reduce the risk of stagnation in the feeding channels 3.

[0024] In this embodiment, a vibratory feeding mechanism 4 is provided on the right side of the frame 1. The vibratory feeding mechanism 4 includes a crossbeam plate 41, multiple springs 42, a lifting cross plate 43, multiple push rods 44, a rotating shaft 45, multiple baffles 46, and a drive assembly. The crossbeam plate 41 is fixedly installed on the right side of the frame 1 and located below the feeding channel 3. Multiple springs 42 are all fixedly installed at the bottom of the crossbeam plate 41 and are evenly arranged. The lifting cross plate 43 is fixedly installed at the bottom of the multiple springs 42. Multiple push rods 44 are all fixedly installed at the top of the lifting cross plate 43, and the multiple push rods 44 are respectively located directly below the corresponding feeding channel 3. The top ends of the multiple push rods 44 all movably penetrate the crossbeam plate 41. The rotating shaft 45 is rotatably installed on the multiple feeding channels 3. Multiple baffles 46 are all fixedly fitted on the rotating shaft 45, and the multiple baffles 46 are respectively located in the corresponding feeding channel 3.

[0025] In this embodiment, the drive assembly is used to control the vertical reciprocating motion of the lifting horizontal plate 43 and to control the rotation of the first rotating shaft 45. The drive assembly includes a support plate 47, a base 48, a motor 49, a second rotating shaft 410, and a cam 411. The support plate 47 is fixedly installed on the rear side wall of the crossbeam plate 41. The base 48 is fixedly installed on the bottom of the support plate 47. The motor 49 is fixedly installed on the bottom of the base 48. The second rotating shaft 410 is fixedly installed on the output shaft end of the motor 49 and located below the lifting horizontal plate 43. The cam 411 is fixedly sleeved on the second rotating shaft 410 and abuts against the bottom of the lifting horizontal plate 43. The motor 49 is used to control the rotation of the second rotating shaft 410 and the cam 411. Utilizing the transmission characteristics of the cam 411 and in conjunction with the elastic force of the spring 42, the lifting horizontal plate 43 can reciprocate vertically. The lifting horizontal plate 43 forms a periodic knocking vibration on the feeding channel 3 through the push rod 44, which can stimulate the feeding channel 3. The solder balls inside form a continuous vibration to guide the flow, effectively avoiding the blockage caused by solder ball accumulation, and ensuring the smoothness of the feeding process. The wiring and control methods of the motor 49 are mature technologies in this field and have been fully disclosed, so they will not be described in detail here. The drive assembly also includes a main pulley 412, an auxiliary pulley 413 and a belt 414. The main pulley 412 is fixedly sleeved on the front end of the second rotating shaft 410, and the auxiliary pulley 413 is fixedly sleeved on the front end of the first rotating shaft 45. The belt 414 is tensioned and sleeved on the main pulley 412 and the auxiliary pulley 413. By utilizing the transmission action of the main pulley 412, the auxiliary pulley 413 and the belt 414, the second rotating shaft 410 and the first rotating shaft 45 can be controlled to rotate simultaneously. The first rotating shaft 45 drives the baffle 46 to rotate in the feeding channel 3, which can intermittently block the amount of solder balls fed, thereby avoiding excessive solder balls from affecting the smooth progress of subsequent processing steps.

[0026] In this embodiment, the top of the crossbeam plate 41 is provided with multiple clearance holes, and the top ends of multiple top rods 44 pass through the corresponding clearance holes. The design of the clearance holes can ensure that the top rods 44 move smoothly vertically back and forth without touching the crossbeam plate 41.

[0027] In this embodiment, the number of cams 411 is set to multiple, and the multiple cams 411 are distributed at equal intervals. The design of multiple cams 411 can ensure that the force is balanced when pushing the support plate 47 to move.

[0028] In this embodiment, vertical guide rods 415 are fixedly installed at the four bottom corners of the crossbeam plate 41. The lifting cross plate 43 is slidably sleeved on the four vertical guide rods 415. The design of the vertical guide rods 415 can guide the movement direction of the lifting cross plate 43, ensuring that the lifting cross plate 43 maintains vertical movement.

[0029] In this embodiment, a support beam 5 is fixedly installed on the right side of the frame 1, and the front end of the second rotating shaft 410 is rotatably installed on the rear side wall of the support beam 5. The design of the support beam 5 can enhance the stability of the second rotating shaft 410 during rotation.

[0030] With the above structure, the working principle of the multi-channel vibratory parallel ball feeding and dispensing device provided in this application is as follows:

[0031] First, the solder balls are poured into the solder ball container 2. Since the bottom inner wall is inclined, the solder balls naturally roll to the right under the action of gravity and smoothly enter the multiple evenly distributed and inclined feeding channels 3. The inclined feeding channels 3 further utilize the weight of the solder balls to provide initial power for their conveying, reducing the possibility of stagnation in the feeding channels 3. This realizes multi-channel conveying of solder balls and forms multiple solder ball flows for distribution and feeding.

[0032] During the unloading process, the motor 49 is controlled to run, and its output shaft drives the rotating shaft 410 and multiple cams 411 to rotate. During the rotation, the cams 411 abut against the bottom of the lifting horizontal plate 43. Combined with the elastic force of the spring 42 at the bottom of the beam plate 41, the lifting horizontal plate 43 moves vertically back and forth along the vertical guide rods 415 at the four corners. The multiple push rods 44 at the top of the lifting horizontal plate 43 move synchronously, which can form a periodic knocking vibration on the corresponding unloading channel 3 above. This continuous vibration can effectively disturb the solder balls in the unloading channel 3, avoid the phenomenon of ball blockage due to accumulation, and ensure that the solder balls are unloaded smoothly.

[0033] Meanwhile, the second rotating shaft 410 drives the first rotating shaft 45 to rotate synchronously through the transmission action of the main pulley 412, the auxiliary pulley 413 and the belt 414. The multiple baffles 46 on the first rotating shaft 45 rotate in the corresponding feeding channel 3 to intermittently block the amount of solder balls fed, ensuring that the amount of solder balls output is appropriate and preventing excessive feeding from affecting subsequent processing steps. Finally, under the coordinated control of gravity, vibration thrust and baffles 46, the solder balls are fed in parallel and orderly through multiple feeding channels to meet the needs of the ball-planting process.
