The delivery outlet of balancing pole feed unit 1 is located the bottom, and receiving unit 2 is located the below of balancing pole feed unit 1, and receives first driving piece 3 to carry out the removal between receiving station and snatching the station. The receiving unit 2 receives one or more pairs of balance bars output by the balance bar feeding unit 1 at the receiving station, then moves to the grabbing station to wait for the manipulator to take away the balance bars, in the process, the balance bars fall into the receiving unit 2 in a lying state, are adjusted to be in a state that a straight bar section is arranged above and a hook section is arranged below by the receiving unit 2, are preferably in a vertical state, and reduce the interval between two balance bars in the pair of balance bars so as to be consistent with the clamping interval of the balance bars on the manipulator.
The balance bar feeding unit 1 can adopt the prior patent of the company, and the patent publication number is CN214203530U; another patent available in the company can be adopted, and the patent publication number is CN209708888U; the embodiment will not be described in detail.
The receiving unit 2 comprises a second driving member 21, a first supporting plate 22 driven by the second driving member 21 to move up and down, a third driving member 23 fixed on the first supporting plate 22, a first receiving plate 24 driven by the third driving member 23 to move horizontally and linearly, a third receiving plate 25 connected with the first receiving plate 24 through a first connecting rod 211 and arranged horizontally and movably, a second receiving plate 26 fixed at the end position of the moving path of the third receiving plate 25, and a jacking unit 27 arranged on the first supporting plate 22 and jacking balance bars in all the receiving plates upwards. The first support plate 22 is moved up and down by the second driving member 21 so that the surfaces of all the receiving plates are effectively butted with the bottom of the balance bar feeding unit 1.
The side edges of the first receiving plate 24 facing the third receiving plate 25, the side edges of the third receiving plate 25 facing the first receiving plate 24 and the second receiving plate 26, and the side edges of the second receiving plate 26 facing the third receiving plate 25 are each provided with a receiving groove 28 for receiving a balance bar.
In this embodiment, the first receiving plate 24, the third receiving plate 25 and the second receiving plate 26 are formed together with a receiving slot 28 for carrying two sets of balance bars, which may be of the same or different specifications. The balance bars carried by the corresponding receiving grooves on the two adjacent receiving plates form a pair of balance bar groups for assembling the key caps, and according to different key cap shapes, the balance bar groups possibly comprise two balance bars with the same specification and size and also possibly comprise two balance bars with different specifications and sizes, but the positions of the two balance bars correspond to the assembling positions on the keyboard.
In this embodiment, the receiving slot 28 includes a supporting and limiting slot 281 for carrying a straight rod section of a balance rod, and an avoiding notch 282 located at two ends of the supporting and limiting slot 281 for enabling the hook section of the balance rod to rotate to a vertical state around the straight rod section under the action of dead weight. The avoidance gap 282 is arranged in a penetrating way from bottom to top. Because the receiving groove 28 only has a supporting part for supporting the straight rod section of the balance rod, but no supporting for the hook section of the balance rod, when the balance rod is transferred into the receiving groove 28, the straight rod section is supported and limited by the supporting limiting groove 281, and the hook section is turned around the straight rod section to be in a vertical state under the action of dead weight, and the hook section is turned and moved into the avoiding notch 282.
In other embodiments, the inner wall of one side of the relief notch 282 may also be configured as an inclined surface to define an angle of rotation of the balance bar hook segment, the angle of rotation of the hook segment being greater than 0 ° and less than or equal to 90 °.
In this embodiment, the adjustment of the spacing between the balance bars is also achieved while changing the state of the balance bars. Specifically, the distance between the receiving grooves 28 can be adjusted by adjusting the distance between the two adjacent receiving plates, so that the adjustment of the distance between the two adjacent balance bars is realized. If only the balance bar is to be adjusted from the lying state to the vertical state, the receiving groove 28 can be arranged at the edge position of one side of the receiving plate, or can be arranged at the middle position of the receiving plate, and the avoiding notch 282 is an internal notch to provide a turnover space for the turnover of the hook section of the balance bar. The receiving groove 28 is arranged at the edge of one side of the receiving plate, so that the distance between the matched balance bars can be further reduced to be smaller, and the synchronous installation requirement of the two balance bars can be met.
In order to realize the change of the spacing between the first receiving plate 24, the third receiving plate 25 and the second receiving plate 26, in this embodiment, the first receiving plate 24 and the third receiving plate 25 are all movably disposed on the same straight line path, a sliding channel formed by a pair of side limiting baffles 29 is disposed in the receiving unit 2, the first receiving plate 24 and the third receiving plate 25 are movably disposed in the sliding channel, sliding rails 210 are disposed on inner walls of two sides of the sliding channel, and sliding grooves 241 matched with the sliding rails 210 are disposed on two opposite sides of the first receiving plate 24 and the third receiving plate 25.
The first material receiving plate 24 is connected with the third material receiving plate 25 through a first connecting rod 211, one end of the first connecting rod 211 is fixedly connected with the third material receiving plate 25, the other end of the first connecting rod 211 is movably connected with the first material receiving plate 24, the first material receiving plate 24 is provided with a movable space in the moving direction, the first material receiving plate 24 can move relative to the third material receiving plate 25 along the first connecting rod 211, the maximum opening distance between the first material receiving plate 24 and the third material receiving plate 25 is limited through the first connecting rod 211, and the first material receiving plate 24 and the third material receiving plate 25 can move to a side surface attaching state so as to achieve the minimum distance between the first material receiving plate 24 and a receiving groove 28 on the third material receiving plate 25. In other embodiments, similarly, one end of the first connecting rod 211 may be fixedly connected to the first receiving plate 24 and movably connected to the third receiving plate 25.
The third receiving plate 25 is connected with the second receiving plate 26 through a second connecting rod 212, one end of the second connecting rod 212 is fixedly connected with the second receiving plate 26, the other end of the second connecting rod 212 is movably connected with the third receiving plate 25, the third receiving plate 25 is provided with a movable space in the moving direction, the third receiving plate 25 can move relative to the second receiving plate 26 along the second connecting rod 212, the maximum opening distance between the third receiving plate 25 and the second receiving plate 26 is limited by the second connecting rod 212, and the third receiving plate 25 and the second receiving plate 26 can move to a side surface bonding state so as to achieve the minimum distance between the third receiving plate 25 and the receiving groove 28 on the second receiving plate 26. In other embodiments, similarly, one end of the second connecting rod 212 may be fixedly connected to the third receiving plate 25 and movably connected to the second receiving plate 26.
The ejection unit 27 comprises a fourth driving member 271, a second supporting plate 272 driven by the fourth driving member 271 to move up and down, and a plurality of ejection posts 273 fixed on the second supporting plate 272, wherein the positions of the ejection posts 273 are in one-to-one correspondence with the positions of avoiding gaps 282 in the receiving grooves 28 in all the receiving plates in a close state. Because the distance between the avoidance notches 282 in the two adjacent receiving grooves 28 is very small when all receiving plates are in the closed state, if the positions of the avoidance notches 282 in the two adjacent receiving grooves 28 are relatively corresponding, one ejection column 273 can be shared, and the ejection column 273 comprises a side limiting protrusion 2731 and ejection platforms 2732 positioned on two opposite sides of the side limiting protrusion 2731. If the positions of the avoidance notches 282 in the two adjacent receiving slots 28 are not relatively corresponding, one avoidance notch 282 is correspondingly provided with a material ejection column 273, and only one material ejection platform 2732 needs to be arranged on the material ejection column 273.
When the balance bar in the vertical state is jacked up, the balance bar can be ensured to be in the vertical state after being jacked up through the cooperation of the side limiting protrusions 2731 on the jacking column 273 and the inner wall of the avoidance notch 282, so that the position accuracy of the manipulator for taking materials is ensured.
The embodiment also provides a balancing rod feeding method, which comprises the following steps:

3) The space between two adjacent receiving plates is reduced, and then the space between two adjacent matched receiving grooves 28 is shortened;
4) After all receiving plates move in place, the lifting columns 273 are utilized to move upwards to be inserted into the avoiding gaps 282, the hook sections of the balance bars are lifted upwards, the straight rod sections of the balance bars move out of the supporting limiting grooves 281, and the balance bar clamping mechanisms are taken away to realize feeding.
The embodiment also provides a high-efficiency installation method of the balance bar, which comprises the steps of outputting at least one pair of balance bars with the same interval as the interval of the corresponding installation holes on the keyboard by utilizing the balance bar feeding method, clamping one ends of the straight bar sections of the two balance bars by a manipulator, keeping the straight bar sections of the balance bars in an inclined state (namely, one ends of the straight bar sections are high and the other ends of the straight bar sections are low), aligning the hook sections at the low ends of the height with the installation holes on the keyboard, horizontally inserting the hook sections into the set positions, and then applying downward extrusion force to the straight bar sections, wherein the extrusion position is positioned between the middle of the straight bar sections and one end with higher height; under the action of extrusion force, the hook section at the other end is inserted into the corresponding mounting hole in a rebound mode after deformation, and then the balance rod is laid down to finish the mounting.
In this embodiment, the vertical state of the balance bar is not an absolute 90 ° state with respect to the horizontal plane, but may be a substantially vertical state, and the effect of installing the balance bar in this state is optimal, and the structural design of the receiving groove 28 and the ejector unit 27 is the simplest, and the balance bar is not damaged. In other embodiments, the balance bar can be installed in an inclined state, so long as one end of the straight bar section is high and the other end is low during installation, then the hook section at the low end is firstly installed into the corresponding installation hole, and then the hook section at the high end is pressed into the corresponding installation hole in a manner of pressing the straight bar section.
In the prior art, since the balance bars are fed and output through the cartridge clip, and are in a lying state, at most two balance bars can be output on the same cartridge clip, and the hook sections of the two balance bars are placed opposite to the hook sections, in this state, the space between the balance bars cannot be further reduced to the space when the balance bars are mounted on the keyboard. Therefore, the application firstly adjusts the pair of balance bars to be in a vertical state or in an inclined state with a set angle, which is convenient for clamping on one hand and provides conditions for further reducing the interval between the balance bars on the other hand. When the two balance bars are in a set state and the distance between the two balance bars is adjusted to be corresponding to the installation holes in the installation position of the keyboard, synchronous installation can be realized by clamping the two balance bars through the mechanical arm, the installation of the two balance bars is completed at one time, and the installation efficiency is greatly improved.
