Description

Technical Field

[0001] This utility model relates to the field of automatic feeding technology, specifically a feeding component for the packaging line of a hearing aid charging case shell. Background Technology

[0002] A hearing aid is a small amplifier that amplifies sounds that were previously inaudible. Utilizing the residual hearing of the hearing-impaired individual, it allows the sound to reach the auditory center of the brain, enabling the person to perceive the sound and providing significant convenience. During the manufacturing process of hearing aids, the pre-molded hearing aid charging case shells need to be packaged for easy storage and transportation. The most common packaging method is manual packaging. A small pile of hearing aid charging case shells is first unloaded from the production line, and then the shells are sequentially placed into the packaging boxes.

[0003] However, the above packaging method is relatively traditional, and the whole process relies on manual operation. After packaging a small pile of shell parts, packaging needs to be stopped, and another small pile of hearing aid charging box shells needs to be dumped on the production line before the packaging work continues. The packaging work cannot be carried out continuously, which reduces work efficiency.

[0004] Therefore, it is necessary to provide a new feeding assembly for the packaging line of a hearing aid charging case to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a feeding component for a hearing aid charging case outer shell packaging line that has a high degree of automation, improves packaging continuity and packaging efficiency.

[0006] To solve the above-mentioned technical problems, the present invention provides a feeding assembly for a hearing aid charging case packaging line, comprising: a base and a support frame fixedly mounted on the top of the base. A first steering shaft is rotatably mounted on the support frame. A first servo motor is fixedly mounted on one side of the support frame. Gears are fixedly fitted on both the output shaft of the first servo motor and the first steering shaft, and the two gears mesh with each other. The top end of the first steering shaft extends above the support frame and is fixedly mounted on a rotating platform. A bearing seat is fixedly mounted on the top of the rotating platform. Side grooves are formed on both sides of the bearing seat, and lifting screws are rotatably mounted in both side grooves. A second servo motor is fixedly installed on the top of the support base. The output shafts of the two second servo motors are respectively fixedly connected to the top ends of the two lifting screws. Lifting connecting arms are threaded onto the two lifting screws. A first mounting frame is fixedly installed on the side of the two lifting connecting arms that is far apart from each other. A second steering shaft is rotatably installed on the side of the two first mounting frames that is far apart from each other. A third servo motor is fixedly installed in the two first mounting frames. The output shafts of the two third servo motors are respectively fixedly connected to the ends of the two second steering shafts that are close to each other. A loading mechanism is provided on the two second steering shafts for scooping up the hearing aid charging case shell.

[0007] Preferably, each of the loading mechanisms includes a second mounting frame, a third steering shaft is rotatably mounted on one side of the second mounting frame, and a shovel is fixedly mounted on one end of the third steering shaft.

[0008] Preferably, a bracket is fixedly installed in the second mounting frame, the third steering shaft passes through the bracket and is rotatably connected to the bracket, a fourth servo motor is fixedly installed on one side of the bracket, and the output shaft of the fourth servo motor is fixedly connected to one end of the third steering shaft.

[0013] Compared with related technologies, the feeding assembly for the packaging line of the hearing aid charging case provided by this utility model has the following advantages:

[0014] This invention, through its shovel mechanism, first steering shaft, bearing seat, and second steering shaft, can automatically scoop up a small pile of hearing aid charging box shells from the material bin and automatically drop them into the surrounding frame via the rotation of the third steering shaft. This achieves an automatic feeding system, eliminating the need for time-consuming and laborious manual unloading of materials for packaging. Packaging personnel only need to stand in front of the packaging platform to perform the packaging. Furthermore, the shovel mechanism is configured with two sets.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figures 1-5 ,in, Figure 1 A schematic diagram of a preferred embodiment of the feeding assembly for the packaging line of a hearing aid charging case shell provided by this utility model; Figure 2 This is a schematic diagram of the connection structure between the first steering shaft and the rotary table in this utility model; Figure 3 This is a schematic diagram of the oblique upward view of the first mounting frame and shovel bucket in this utility model; Figure 4 This is a cross-sectional view of the support structure in this utility model; Figure 5 This is a schematic diagram of the connection structure between the frame connector and the third steering shaft of this utility model. The feeding assembly for the packaging line of the hearing aid charging case includes: a base 1 and a support frame 2 fixedly mounted on the top of the base 1. One side of the support frame 2 is open, and to ensure stable support, two support columns are fixed at the opening. A first steering shaft 3 is rotatably mounted on the support frame 2. A first servo motor is fixedly mounted on one side of the support frame 2, and gears are fixedly fitted on both its output shaft and the first steering shaft 3. The two gears mesh. The top of the first steering shaft 3 extends above the support frame 2 and a rotary table 4 is fixedly mounted thereon. A bearing seat 5 is fixedly mounted on the top of the rotary table 4. Side grooves 6 are opened on both sides of the bearing seat 5, and lifting screws 7 are rotatably mounted in both side grooves 6. A second servo motor is fixedly mounted on the top of the bearing seat 5. The output shafts are fixedly connected to the top ends of the two lifting screws 7 respectively. Lifting connecting arms 8 are threaded on both lifting screws 7. A first mounting frame 9 is fixedly installed on the side of the two lifting connecting arms 8 that is far apart from each other. In order to ensure the stability of the lifting connecting arms 8 during the lifting movement, guide columns are fixedly installed in the two side grooves 6. The two guide columns pass through the two lifting connecting arms 8 respectively and slide to fit the corresponding lifting connecting arms 8. A second steering shaft 10 is rotatably installed on the side of the two first mounting frames 9 that is far apart from each other. A third servo motor is fixedly installed in the two first mounting frames 9. The output shafts of the two third servo motors are fixedly connected to the ends of the two second steering shafts 10 that are close to each other. A loading mechanism is provided on the two second steering shafts 10 to pick up the hearing aid charging box shell.

[0023] Each of the aforementioned loading mechanisms includes a second mounting frame 11. A third steering shaft 13 is rotatably mounted on one side of the second mounting frame 11, and a shovel 14 is fixedly mounted on one end of the third steering shaft 13. A bracket 12 is fixedly mounted inside the second mounting frame 11. The third steering shaft 13 passes through the bracket 12 and is rotatably connected to the bracket 12. A fourth servo motor is fixedly mounted on one side of the bracket 12, and its output shaft is fixedly connected to one end of the third steering shaft 13. This allows the shovel 14 to be rotated, thereby turning over the shovel 14 containing the hearing aid charging case shell workpiece and emptying the workpiece. The shell of the shovel 14 is covered with a rubber outer skin to prevent scratches on the hearing aid charging case shell.

[0024] In this method, in order to limit the maximum rotation angle of the shovel 14, two blocking rods 15 are fixedly installed on the outer walls of the two first mounting frames 9 on opposite sides. In the initial state, the top of the second mounting frame 11 is in contact with the corresponding blocking rod 15. When the shovel 14 finishes shoveling the outer shell workpiece and rotates from one side to the other, the bottom of the second mounting frame 11 will rotate to contact the corresponding blocking rod 15, thereby achieving the limiting function.

[0025] In this method, in order to load a large number of hearing aid charging case shell parts, a material box 16 is fixedly installed on the top of the base 1. The material box 16 is relatively deep and has a large capacity, which can store a large number of shell parts at one time. In the initial state, the material box 16 is located below one of the loading mechanisms. A packaging platform 17 is fixedly installed on the top of the base 1, and the packaging platform 17 is located below another loading mechanism. In addition, a guide ramp 18 is fixedly installed on the side of the packaging platform 17 near the support frame 2. The top surfaces of the guide ramp 18 and the packaging platform 17 are both made of stainless steel with a smooth finish to ensure that the shell parts are not scratched. The same surrounding frame 19 is fixedly installed on the packaging platform 17 and the guide ramp 18. The guide ramp 18 can guide the shell parts poured out of the hopper 14 into the surrounding frame 19, thereby temporarily forming a small pile of shell parts, which is convenient for the packaging personnel standing in front of the packaging platform 17 to carry out the packaging work.

[0026] The working principle of the feeding assembly for the packaging line of the hearing aid charging case provided by this utility model is as follows:

[0027] Before the packaging work, pour enough hearing aid charging box shell parts into the material box 16, and the packaging personnel stand in front of the packaging platform 17 to wait for the packaging work. The packaging station is located on the side of the surrounding frame 19 away from the guide ramp 18.

[0028] When starting work, the third servo motor above the material box 16 is started first. Its output shaft drives the second steering shaft 10 to rotate, thereby rotating the entire loading mechanism. When the shovel 14 in the loading mechanism rotates into the material box 16 and contacts the shell workpiece, it begins to shovel the shell workpiece. When the shovel 14 rotates out of the material box 16, a small pile of shell workpieces has been shoveled inside the shovel 14. The third servo motor is turned off after the second mounting frame 11 rotates to contact the corresponding blocking rod 15. Then, the first servo motor is started in the forward direction. Through the meshing of two gears, the rotary table 4 and the carrier 5 can be rotated. When the carrier 5 rotates 180°, the first servo motor is turned off. At this time, the shovel 14 with the shell workpiece is located above the guide ramp 18, while the other empty shovel 14 is located above the material box 16.

[0029] At this time, the second servo motor corresponding to the hopper 14 containing the outer shell workpiece is started in the forward direction. Its output shaft drives the corresponding lifting screw 7 to rotate, so that the corresponding lifting connecting arm 8 carries the corresponding hopper 14 down and finally brings it to the top of the guide ramp 18. Then, the corresponding fourth servo motor is started, and its output shaft drives the third steering shaft 13 to rotate, which in turn can rotate the corresponding hopper 14. When the top opening of the hopper 14 gradually flips to face downward, the outer shell workpiece inside falls into the guide ramp 18 and then falls into the surrounding frame 19. Then, the packaging personnel can carry out the packaging work on the outer shell workpiece.

[0030] While the packaging process is underway, the fourth servo motor is first started in reverse to flip the hopper 14 back over. Then, the second servo motor is started in reverse to bring the lowered lifting arm 8 back to its original height. Subsequently, the third servo motor located above the material box 16 is started, which rotates the corresponding hopper 14 to scoop up the outer shell workpieces in the material box 16. After scooping, the first servo motor is started in reverse to reverse the bearing seat 5. After it reverses 180°, the first servo motor is turned off. At this time, the hopper 14 that scoops up the outer shell workpieces for the second time rotates to the top of the guide ramp 18, and the empty hopper 14 returns to the top of the material box 16. When the previous batch of outer shell workpieces is about to be packaged, the same operation is performed to flip the hopper 14 containing the outer shell workpieces and pour out the outer shell workpieces. The packaging process can then continue. At this time, the packaging process will not stop and will continue.

[0031] Furthermore, the above operation is repeated until the top end of the hearing aid charging case shell workpiece in the material box 16 descends. In order to ensure that the shovel 14 can continue to scoop up the shell workpiece, the corresponding second servo motor can be started before rotating the shovel to lower the shovel 14 slightly, so that the shovel 14 can smoothly scoop up the shell workpiece. When the shell workpiece in the material box 16 is almost scooped out, enough hearing aid charging case shell workpieces can be poured back into it.

[0032] Compared with related technologies, the feeding assembly for the packaging line of the hearing aid charging case provided by this utility model has the following advantages:

[0033] This utility model provides a feeding component for a hearing aid charging case shell packaging line. Through the setting of components such as a shovel mechanism, a first steering shaft 3, a bearing seat 5, and a second steering shaft 10, it can automatically shovel up a small pile of hearing aid charging case shell workpieces in the material bin 16 and automatically drop them into the surrounding frame 19 through the flipping of the third steering shaft 13. This forms an automatic feeding method, eliminating the need for manual time and effort to pour out a portion of the material for packaging. Packaging personnel only need to stand in front of the packaging platform 17 to carry out packaging. Furthermore, the shovel mechanism is set with two sets. When one set of shovel mechanisms is pouring material, the other set can shovel material. By rotating, the shovel hopper 14 containing the material is quickly brought to the top of the guide ramp 18, thereby speeding up the automated feeding speed and improving the overall packaging efficiency.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
