As shown in fig. 1 and 2, the keyboard shaft feeding device includes a vibration plate 1, a feeding rail 2, and a position adjusting mechanism. The vibration plate 1 has a spiral posture adjustment rail 11 therein. The posture adjustment rail 11 is used to adjust the keyboard shaft 10 to a set posture in the course of transferring the keyboard shaft 10. In the set posture, the key head of the keyboard shaft 10 faces upward. The discharge hole of the attitude adjusting track 11 is connected with the feed inlet of the feeding track 2. The feeding rail 2 is used for feeding the keyboard shaft 10 to the feeding station. The position adjusting mechanism is used for adjusting the position of the keyboard shaft 10 in the feeding track 2, so that the keyboard shafts 10 in the feeding track 2 are sequentially arranged at intervals.
The position adjusting mechanism can adjust the positions of the keyboard shafts 10 in the feeding track 2, so that the keyboard shafts 10 in the feeding track 2 are sequentially arranged at intervals, when the keyboard shafts 10 at the feeding position are clamped away, the next keyboard shaft 10 can be rapidly moved to the feeding position, and the feeding efficiency is high.
As shown in fig. 6 and 7, the feeding mechanism includes a frame 51, a robot arm 52, a turntable 53, and a first driving mechanism. The turntable 53 is rotatably arranged on the frame 51, and the turntable 53 is used for driving the manipulator 52 to sequentially rotate to the feeding station, the shaping station and the shaft inserting station along the same direction. The first driving mechanism is used for driving the turntable 53 to rotate so as to drive the manipulator 52 to circulate among the feeding station, the shaping station and the shaft inserting station in sequence. The robot 52 is used for holding the keyboard shaft 10 when rotating to the loading station with the turntable 53, and inserting the keyboard shaft 10 into the shaft groove of the mold 200 when rotating to the shaft inserting station with the turntable 53. The shaping mechanism 12 is used for shaping the keyboard shaft 10 clamped by the manipulator 52 at a shaping station so as to shape the keyboard shaft 10 to a set posture during shaft insertion, and the axis of the keyboard shaft 10 is vertical.
In the above-mentioned technical solution, the keyboard shaft feeding device of the shaft inserting apparatus 100 for a keyboard can feed the keyboard shaft 10 to the feeding station, and the manipulator 52 of the feeding mechanism can take away the keyboard shaft 10 of the feeding station and transfer it to the shaft inserting station to insert into the shaft groove of the mold 200. The shaft inserting equipment 100 for the keyboard can automatically feed and feed the keyboard shaft 10, and has high working efficiency.
In addition, through the arranged shaping mechanism 12, the shaping mechanism 12 can shape the keyboard shaft 10 on the manipulator 52 between the feeding station and the shaft inserting station of the manipulator 52 so as to shape the keyboard shaft 10 to the set posture during shaft inserting, so that the position of the keyboard shaft 10 in the feeding process can be effectively prevented from deviating, and the shaft inserting success rate of the keyboard shaft 10 is improved.
As shown in fig. 1 and 6, the number of the robot arms 52 may be four, and the robot arms are evenly distributed on the edge of the turntable 53 in a circular shape. The aforementioned first drive mechanism may include a motor 54. The motor 54 is used for driving the turntable 53 to rotate so as to drive each mechanical arm 52 to cycle among the feeding station, the shaping station and the shaft inserting station in sequence. Wherein, the motor shaft of the motor 54 is used for driving the turntable 53 to rotate 1/4 circles when rotating one circle.
In the technical scheme provided above, by increasing the number of the manipulators 52 to 4, the four manipulators 52 can feed the keyboard shaft 10 in a circulating manner, and the feeding efficiency is higher compared with that of a single manipulator 52 in the prior art.
In order to realize the function of shaping the keyboard shaft by the shaping mechanism 12, the invention also provides the following technical scheme: as shown in fig. 3 and 4, the shaping mechanism 12 includes a second driving mechanism, a first fixing block 121, a first shaping arm 122, and a second shaping arm 123. The first fixing block 121 is disposed on the frame 51. The first fixing block 121 is provided with a first limit chute 1211. First shaping arm 122 and second shaping arm 123 are both disposed within first limit slide 1211. The second driving mechanism is used to drive both the first shaping arm 122 and the second shaping arm 123 relatively close to or away from each other. The manipulator 52 is used for clamping two sides of the keyboard shaft 10 in the length direction, and the first shaping arm 122 and the second shaping arm 123 are used for shaping two sides of the keyboard shaft 10 clamped by the manipulator 52 in the width direction when the two arms approach each other, so that the axis of the keyboard shaft 10 is vertical.
With the above arrangement, since the manipulator 52 clamps both sides in the length direction of the keyboard shaft 10, both sides in the length direction of the keyboard shaft 10 are limited, so that when the first shaping arm 122 and the second shaping arm 123 clamp both sides in the width direction of the keyboard shaft 10, all four sides of the keyboard shaft 10 are clamped, and the keyboard shaft 10 can be shaped to an insertion shaft setting posture in which the axis is vertical.
Further, as shown in fig. 4, the aforementioned second driving mechanism may include a first driving cylinder 125, a first link 126, and a second link 127. The piston rod 1251 of the first drive cylinder 125 is vertically disposed and the first limit slide 1211 is horizontally disposed. The frame is provided with a fixed support frame 124. The first driving cylinder 125 is disposed inside the fixed support 124, and the first fixing block 121 is disposed at an upper end of the fixed support 124. The first position-limiting sliding groove 1211 has a position-avoiding hole 1212 at a bottom surface thereof. One end of the first link 126 is hinged to the lower end of the first shaping arm 122 via the clearance hole 1212, and the other end is hinged to the piston rod 1251 of the first driving cylinder 125. One end of the second link 127 is hinged to the lower end of the second shaping arm 123 via the clearance hole 1212, and the other end is hinged to the piston rod 1251 of the first driving cylinder 125.
Through the above arrangement, when the piston rod 1251 of the first driving cylinder 125 moves, the first connecting rod 126 and the second connecting rod 127 can drive the first shaping arm 122 and the second shaping arm 123 to relatively move closer and farther along the first limit sliding slot 1211, which is convenient to implement.
The feeding track 2 is provided with a detection position, and the alarm mechanism is used for sending out an alarm response when the detection position is detected to be empty. Wherein, through the alarm mechanism who sets up, send out the warning response when detecting the position and empty, warn the operation personnel in time to handle this unusual condition to prevent to get the condition emergence of expecting manipulator 52 and getting the material failure.
In a specific application example, as shown in fig. 5, the aforementioned alarm mechanism may include a sensor 7, a processing unit 8, and an alarm unit 9. The sensor 7 is configured to generate a first signal when it detects that the detection bit is empty. The processing unit 8 is configured to generate an alarm signal based on the first signal. The alarm unit 9 is used for sending out an alarm response according to the alarm signal.
Through the setting, the automatic detection of the detection position can be realized through the cooperation of the sensor 7, the processing unit 8 and the alarm unit 9, the labor is saved, and the efficiency is higher.
The aforementioned feeding rail 2 may include a rail groove to feed the keyboard shaft 10 through the rail groove, so that the keyboard shaft 10 moves along the rail groove. The track groove has opposing first and second groove walls. The track groove is provided with an avoiding hole which penetrates through the first groove wall and the second groove wall at the detection position. As shown in fig. 2, the aforementioned sensor 7 may be a correlation type photoelectric sensor. The opposite-type photosensor has an emission end 71 and a reception end 72. The transmitting end 71 is located at one side of the clearance hole, and the receiving end 72 is located at the other side of the clearance hole.
The width of the track groove may be the same as the width of the keyboard shaft 10 when in the set posture, so that the formed limiting structure limits the keyboard shaft 10. In this example, the shape of the track groove is designed to be consistent with the width of the keyboard shaft 10 when in a set posture so as to limit the keyboard shaft 10, and the structure is relatively simple and convenient to implement.
In one example, the aforementioned alarm unit 9 may include a display screen for displaying warning text information according to the alarm response. For example, the warning text message may be "NG" or the like.
In another example, the aforementioned alarm unit 9 may comprise an alarm. The alarm is used for giving out alarm sound according to the alarm signal so as to give out sound alarm to the operator and prompt the operator to process abnormal conditions in time.
As shown in fig. 1 and 2, the aforementioned position adjustment mechanism may include an air tube 3. The position adjusting mechanism blows air to the keyboard shafts 10 in the feeding track 2 through the air blowing openings of the air pipes 3, so that the keyboard shafts 10 in the feeding track 2 are sequentially arranged at intervals. In this example, the air tube 3 blows air to the keyboard shafts 10 in the feeding track 2 to additionally provide power for the keyboard shafts 10 to advance along the feeding track 2, so that no space exists between two adjacent keyboard shafts 10.
Furthermore, flow control valve can be arranged on the air pipe 3 to control the flow velocity of the air in the air pipe 3, so that the force for blowing the keyboard shaft 10 to the air pipe 3 can be adjusted according to the actual site working condition, and the practicability is strong.
As shown in fig. 2, the aforementioned gas tube 3 may include a metal tube segment 31 and a plastic tube segment 32. One end of the metal tube section 31 is detachably connected to one end of the plastic tube section 32. Specifically, the length of the metal pipe section 31 is short, mainly to increase the length of the gas blowing section. The plastic pipe section 32 is provided to utilize the flexibility of the plastic pipe section 32 for convenient routing.
As shown in fig. 2, the aforementioned air tube 3 blows air on the keyboard shaft 10 in the feed rail 2 through the end of the metal tube section 31 facing away from the plastic tube section 32. The feeding rail 2 is provided with the support frame 4, the metal pipe section 31 is rotatably arranged on the support frame 4, so that the blowing direction of the blowing port can be adjusted, the requirements of different working conditions can be met, and the practicability is high.
In order to realize the effect that the metal pipe section 31 can rotate relative to the support frame 4, the invention also provides the following technical scheme: as shown in fig. 2, the keyboard shaft feeding device further comprises a second fixing block 5, the second fixing block 5 is rotatably connected with the support frame 4, and the metal pipe section 31 is connected with the second fixing block 5 so as to rotate relative to the support frame 4 through the second fixing block 5. Specifically, the second fixing block 5 may be provided with a through hole for the metal pipe section 31 to pass through, and the metal pipe section 31 is in transition fit with a hole wall of the through hole, so that the metal pipe section 31 is conveniently detached from the second fixing block 5.
In order to improve the connection stability between the metal pipe section 31 and the plastic pipe section 32, it is preferable that one end of the metal pipe section 31 has a threaded section, and one end of the plastic pipe section 32 is sleeved on the threaded section. The friction resistance at the joint of the metal pipe section 31 and the plastic pipe section 32 is improved through the arranged thread section, and the metal pipe section and the plastic pipe section are prevented from loosening.
Further, as shown in fig. 2, the keyboard shaft feeding device of the present invention may further include a yoke 6. The clamp 6 is used to clamp one end of the plastic pipe section 32 to the threaded section, so as to further improve the connection stability between the metal pipe section 31 and the plastic pipe section 32.
Further, as shown in fig. 7, the manipulator 52 may include a fixed frame 521, a movable block 522, a clamping mechanism 523, and a third driving mechanism. The fixing bracket 521 is provided on the turntable 53. The movable block 522 is arranged on the fixed frame 521 in a lifting way. The third driving mechanism is used for driving the movable block 522 to ascend and descend. The clamping mechanism 523 is arranged on the movable block 522, and the clamping mechanism 523 is used for lifting along with the movable block 522 so as to clamp the keyboard shaft 10 when moving to the loading station and insert the keyboard shaft 10 into the shaft groove of the mold 200 when moving to the shaft inserting station.
Specifically, when the turntable 53 drives the manipulator 52 to move to the feeding station, the third driving mechanism drives the movable block 522 to descend, the movable block 522 drives the clamping mechanism 523 to clamp the keyboard shaft 10 at the feeding station, and then the third driving mechanism drives the clamping mechanism 523 to ascend through the movable block 522. Then the turntable 53 drives the manipulator 52 to move to the shaft inserting station, at this time, the third driving mechanism drives the movable block 522 to descend again, the movable block 522 drives the clamping mechanism 523 to insert the keyboard shaft 10 into the mold 200 at the shaft inserting station, and then the third driving mechanism drives the clamping mechanism 523 to ascend through the movable block 522, and the process is repeated.
The fixing frame 521 may be provided with a sliding rail. The slide rail is vertically arranged. The movable block 522 is disposed on a slide rail, and the slide rail is used for guiding the lifting of the movable block 522 so as to improve the motion accuracy of the movable block 522.
As shown in fig. 7, the aforementioned third driving mechanism may include a lift driving cylinder 524 to drive the movable block 522 to be lifted along the slide rail by the lift driving cylinder 524.
The lifting cylinder 524 is a commercially available part, which is convenient to acquire and implement. The lifting driving cylinder 524 may be an air cylinder or a hydraulic cylinder, and may be specifically selected according to actual conditions.
As shown in fig. 8, the clamping mechanism 523 may include a clamping arm 55 and a fourth driving mechanism. The clamp arm 55 is disposed on the movable block 522. Clip arm 55 includes a first clip arm 551 and a second clip arm 552. The fourth driving mechanism serves to drive both the first clip arm 551 and the second clip arm 552 relatively close to grip the keyboard shaft 10 and relatively far away to release the keyboard shaft 10.
Through the arrangement, the purposes of clamping the keyboard shaft 10 and releasing the keyboard shaft 10 can be achieved through the cooperation of the first clamping arm 551 and the second clamping arm 552, the structure is relatively simple, and the implementation is convenient.
As shown in fig. 8, the aforementioned fourth driving mechanism may include an elastic member 60, a second driving cylinder 56, and a driving block 57 provided on a piston rod of the second driving cylinder 56. The movable block 522 has a connecting plate 63 thereon. The connecting plate 63 is provided with a limiting sliding groove 61. The first clip arm 551 is provided with a first sliding part. A second sliding portion is disposed on the second clip arm 552. The first clamping arm 551 is installed in the limit sliding groove 61 through a first sliding part. The second clip arm 552 is mounted in the limiting slide groove 61 via a second sliding portion. The drive block 57 is provided with a tapered section. The first sliding portion is provided with a first tapered surface 581. The second sliding portion is provided with a second tapered surface 591. The first tapered surface 581 is opposite to the second tapered surface 591, and a tapered hole into which the tapered section is inserted is formed therebetween. The tapered section is used for pressing against the first tapered surface 581 and the second tapered surface 591 when being inserted into the tapered hole, so as to push the first arm lock 551 away from the second arm lock 552 through the first tapered surface 581, and push the second arm lock 552 away from the first arm lock 551 through the second tapered surface 591. Spring 60 is configured to provide a force that urges both first clip arm 551 and second clip arm 552 relatively closer together.
Specifically, when the piston rod of the second driving cylinder 56 drives the driving block 57 to be inserted into the tapered hole, the tapered section on the driving block 57 cooperates with the first tapered surface 581 and the second tapered surface 591, so as to drive the first clamping arm 551 and the second clamping arm 552 to relatively move away from each other, so as to release the clamped keyboard shaft 10; when the piston rod of the second driving cylinder 56 drives the driving block 57 to exit the tapered hole, the elastic member 60 applies a force to the first clamping arm 551 and the second clamping arm 552, so that the first clamping arm 551 and the second clamping arm 552 are relatively close to each other to clamp the keyboard shaft 10.
Here, it should be noted that: the tapered hole can be a frustum-shaped hole, namely the tapered hole has no tapered tip.
As shown in fig. 8, the aforementioned connecting plate 63 may have a first side and a second side opposite to each other. The limiting sliding groove 61 is arranged on the first side and penetrates through two ends of the first side. The bottom of the limiting sliding groove 61 is provided with a limiting groove 62 penetrating to the second side. The limit groove 62 is located at the middle of the connection plate 63. The first sliding part is provided with a first convex column 58 which passes through the limit groove 62. The first tapered surface 581 is disposed on the first pillar 58. The second sliding part is provided with a second convex column 59 which passes through the limit groove 62. The aforementioned second tapered surface 591 is provided on the second boss 59.
In the above example, since the limit slide groove 61 penetrates both ends of the first side, the installation of both the sliding portion of the first clip arm 551 and the sliding portion of the second clip arm 552 is facilitated, and specifically, the sliding portion of the first clip arm 551 may be inserted from one side of the limit slide groove 61 and the sliding portion of the second clip arm 552 may be inserted from the other side of the limit slide groove 61. And through the limiting groove 62 that sets up in the bottom of spacing spout 61, limiting groove 62 can be spacing first arm lock 551 and second arm lock 552 through first projection 58 and second projection 59, prevents that first arm lock 551 and second arm lock 552 from deviating from in spacing spout 61.
The elastic member 60 may be annular and may be a rubber member. Elastic member 60 is fitted over the outer sides of both first stud 58 and second stud 59. For example, the elastic member 60 may be a rubber band or the like.
