Description

Technical Field

[0001] This utility model belongs to the field of micro shaft feeding technology, specifically relating to an automatic micro shaft feeding device. Background Technology

[0002] Currently, the loading of inserts or miniature shafts during injection molding is usually done manually or by using a robotic arm.

[0003] Manual placement leads to prolonged and unstable molding cycles, inconsistent product appearance and dimensions, and poor production continuity. It is not only labor-intensive but also prone to misplacement or omissions.

[0004] Using traditional robotic arms for loading is generally not feasible for handling precision inserts, as it can easily lead to improper handling, mold damage, or shaft scratches.

[0005] Therefore, there is an urgent need for an automatic micro shaft feeding device that features high feeding efficiency, accurate positioning, and no scratches on the micro shaft. Utility Model Content

[0006] The purpose of this invention is to provide an automatic micro-shaft feeding device to solve the problems mentioned in the background art. The automatic micro-shaft feeding device provided by this invention features high feeding efficiency, accurate positioning, and no scratches on the micro-shafts.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a micro shaft automatic feeding device, including a vibratory feeder, a guide rail connected to the discharge end of the vibratory feeder, a shaft picking assembly provided on one side of the guide rail, a shaft feeding assembly provided above the shaft picking assembly, the shaft picking assembly including a Z-axis moving seat that can move along the X, Y and Z axes, a tilting cylinder installed on the Z-axis moving seat, a shaft picking plate installed on the output end of the tilting cylinder, a plurality of shaft picking suction sleeves installed on the shaft picking plate, and a shaft feeding assembly including a robot arm, a shaft feeding plate installed on the output end of the robot arm, and shaft feeding suction sleeves corresponding to the shaft picking suction sleeves installed on the shaft feeding plate.

[0008] To enable the miniature shaft to be conveyed backward on the guide rail, a vertical vibrator is further provided below the guide rail.

[0009] To enable the Z-axis moving seat to move in the X, Y, and Z-axis directions, thereby adjusting the position of the corresponding shaft-picking sleeve to pick up the miniature shaft, the shaft-picking assembly further includes a base plate. An X-axis linear module is mounted on top of the base plate, and an X-axis moving seat is connected to the output end of the X-axis linear module. A Y-axis slide cylinder is mounted above the X-axis moving seat, and a Y-axis moving seat is mounted on the output end of the Y-axis slide cylinder. A Z-axis linear module is mounted on the side of the Y-axis moving seat, and the Z-axis moving seat is mounted on the output end of the Z-axis linear module.

[0010] In order to pick up the miniature shaft, one end of the shaft-picking sleeve is provided with a shaft-picking groove, and the other end of the shaft-picking sleeve is provided with a connecting groove that communicates with the shaft-picking groove. The structure of the shaft-feeding sleeve is the same as that of the shaft-picking sleeve.

[0011] To ensure the stability of the micro shaft suction, the connecting groove and the suction groove are further connected by a connecting hole, the inner diameter of which is smaller than the inner diameter of the suction groove.

[0012] To facilitate the suction of the miniature shaft into the suction groove, a flared opening is provided at the outer end of the suction groove.

[0013] In order to achieve a precise fit with the shaft-picking sleeve, thereby picking up the miniature shaft on the shaft-picking sleeve and transferring it to the shaft-feeding sleeve, a lifting slide cylinder is further installed on the output end of the robot arm, and the shaft-feeding plate is installed on the output end of the lifting slide cylinder.

[0014] To achieve the suction and blowing action of the miniature shaft, a triangular air tube is further connected to the shaft feeding and suction sleeve. One end of the horizontal tube of the triangular air tube is the air inlet, and the other end of the horizontal tube is the air outlet. A solenoid valve is installed on the air outlet.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses a vibratory feeder to vibrate and align scattered micro shafts, then uses a shaft-picking and suction sleeve to pick up and position the micro shafts, and finally uses a shaft-feeding and suction sleeve to transport the micro shafts into the mold cavity, thus realizing automatic feeding of micro shafts. Compared with manual feeding or direct feeding by a robotic arm, it has the effects of high feeding efficiency, low labor intensity of workers, and good precision, and will not cause scratches to the micro shafts.

[0018] 3. The shaft feeding and suction sleeve of this utility model realizes the suction and blowing action of the micro shaft through the control of the solenoid valve, which makes the action faster and thus improves the work efficiency, and can also avoid scratching the micro shaft.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1-4The present invention provides the following technical solution: a micro shaft automatic feeding device, including a vibratory plate 1, a guide rail 2 connected to the discharge end of the vibratory plate 1, a shaft picking assembly 4 on one side of the guide rail 2, a shaft feeding assembly 5 above the shaft picking assembly 4, the shaft picking assembly 4 including a Z-axis moving seat 48 movable along the X, Y and Z axes, a tilting cylinder 47 mounted on the Z-axis moving seat 48, a shaft picking plate 46 mounted on the output end of the tilting cylinder 47, a plurality of shaft picking suction sleeves 45 mounted on the shaft picking plate 46, the shaft feeding assembly 5 including a robot arm 51, a shaft feeding plate 53 mounted on the output end of the robot arm 51, a shaft feeding suction sleeve 54 corresponding to the shaft picking suction sleeves 45 mounted on the shaft feeding plate 53, the shaft picking suction sleeves 45 being connected to a vacuum pump through a pipe, and the shaft feeding suction sleeves 54 being connected to an air source through a pipe.

[0027] By adopting the above technical solution, this utility model uses a vibratory plate 1 to vibrate and align the scattered micro shafts, then uses a shaft-picking and suction sleeve 45 to pick up and position the micro shafts, and then uses a shaft-feeding and suction sleeve 54 to transport the micro shafts into the mold cavity, thus realizing automatic feeding of micro shafts. Compared with manual feeding or direct feeding by a robotic arm, it has the effects of high feeding efficiency, low labor intensity of workers, and good precision, and will not cause scratches to the micro shafts.

[0028] Specifically, a straight vibrator 3 is installed below the guide rail 2.

[0029] By adopting the above technical solution, the miniature shaft is transported backward on the guide rail 2.

[0030] Specifically, the axis assembly 4 also includes a base plate 41, an X-axis linear module 410 is mounted on the top of the base plate 41, an X-axis moving seat 42 is connected to the output end of the X-axis linear module 410, a Y-axis slide cylinder 43 is mounted on the top of the X-axis moving seat 42, a Y-axis moving seat 49 is mounted on the output end of the Y-axis slide cylinder 43, a Z-axis linear module 44 is mounted on the side of the Y-axis moving seat 49, and a Z-axis moving seat 48 is mounted on the output end of the Z-axis linear module 44.

[0031] By adopting the above technical solution, the Z-axis moving seat 48 can be moved in the X, Y and Z-axis directions, thereby adjusting the position of the corresponding shaft-picking sleeve 45 to pick up the miniature shaft.

[0032] Specifically, one end of the shaft-collecting sleeve 45 is provided with a shaft-collecting groove 454, and the other end of the shaft-collecting sleeve 45 is provided with a connecting groove 451 that communicates with the shaft-collecting groove 454.

[0033] By adopting the above technical solution, the connecting groove 451 is connected to the vacuum pump through a pipe, so that the suction groove 454 generates negative pressure to suck up the miniature shaft.

[0034] Specifically, a flared opening 453 is provided on the outer end of the suction shaft groove 454.

[0035] By adopting the above technical solution, it is easy to draw the miniature shaft into the shaft suction groove 454.

[0036] Example 2

[0037] The difference between this embodiment and embodiment 1 is that, specifically, the connecting groove 451 and the suction shaft groove 454 are connected by a connecting hole 452, and the inner diameter of the connecting hole 452 is smaller than the inner diameter of the suction shaft groove 454.

[0038] By adopting the above technical solution, the stability of the micro shaft suction is guaranteed.

[0039] Example 3

[0040] The difference between this embodiment and embodiment 1 is that, specifically, a lifting slide cylinder 52 is installed on the output end of the robot arm 51, and a shaft feeding plate 53 is installed on the output end of the lifting slide cylinder 52.

[0041] By adopting the above technical solution, the shaft feeding plate 53 is driven to move up and down, so as to achieve precise cooperation with the shaft picking and suction sleeve 45, thereby picking up the miniature shaft on the shaft picking and suction sleeve 45 and picking it up onto the shaft feeding and suction sleeve 54.

[0042] Example 4

[0043] The difference between this embodiment and embodiment 1 is that, specifically, the structure of the shaft feeding suction sleeve 54 is the same as that of the shaft taking suction sleeve 45. A triangular air tube 55 is connected to the shaft feeding suction sleeve 54. One end of the horizontal tube of the triangular air tube 55 is the air inlet, and the other end of the horizontal tube of the triangular air tube 55 is the air outlet. The middle end of the triangular air tube 55 is connected to the shaft feeding suction sleeve 54. A solenoid valve 56 is installed on the air outlet. The air inlet is connected to an air source, which provides an air pressure of 0.6-1 MPa. This air pressure can ensure stable suction of the micro shaft without scratching the micro shaft.

[0044] By adopting the above technical solution, when the solenoid valve 56 is opened, gas is directly discharged from the outlet end, thereby generating negative pressure at the middle end of the triangular air tube 55, that is, negative pressure is generated at the suction groove of the shaft feeding sleeve 54 to suck up the miniature shaft; when the solenoid valve 56 is closed, gas is discharged from the middle end, blowing the miniature shaft out of the suction groove. The shaft feeding sleeve 54, controlled by the solenoid valve 56, realizes the suction and blowing action of the miniature shaft, which is faster and thus improves work efficiency, and can also avoid scratching the miniature shaft.

[0045] In summary, this invention uses a vibratory feeder 1 to vibrate and align scattered microshafts, then uses a shaft-picking and suction sleeve 45 to pick up and position the microshafts, and finally uses a shaft-feeding and suction sleeve 54 to transport the microshafts into the mold cavity. This achieves automatic feeding of microshafts. Compared with manual feeding or direct feeding by a robotic arm, it has the advantages of high feeding efficiency, low labor intensity for workers, and good precision, and it will not cause scratches to the microshafts. This invention divides the microshaft feeding action into two parts: picking and feeding. The two parts work together to effectively improve the feeding efficiency. The shaft-feeding and suction sleeve 54 of this invention, controlled by a solenoid valve 56, realizes the picking and blowing action of the microshafts, making the action faster and thus improving work efficiency, while also avoiding scratches to the microshafts.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
