The traditional way of installing springs on the middle plate is mainly operated manually, where the springs are manually removed from the spring strip, and then manually placed on the key position of the middle plate for installation. In view of the above-mentioned deficiencies in the traditional way of installing springs on the middle plate, the applicant's client has developed an automatic keyboard spring assembly machine.

[0010] Preferably, the clamping jaw assembly comprises a finger cylinder and a clamping hand, the finger cylinder is connected to the lifting cylinder, and the two clamping hands are transmission-connected to the finger cylinder.

[0011] The beneficial effects of the present invention are as follows: the present invention realizes automatic feeding, automatic positioning, automatic slicing and automatic insertion of spring pieces, has a high degree of automation, reduces the labor intensity of operators, ensures stable insertion and reduces the product defect rate;

[0012] The shrapnel material belt is discharged from the shrapnel material tray, bypasses the sensing shaft and enters the material belt feeding channel, and the paper belt carrying the shrapnel material belt is recovered through the paper belt receiving tray. The sensing shaft is used to sense the material discharge, and the paper belt is sensed by the paper belt adjustment mechanism to receive the paper belt. The applicant has previously installed a photoelectric switch to sense the paper belt, but because the paper belt is light and cannot be sensed during the winding process, the receiving paper belt is unstable and cannot be received.

After all the shrapnel are installed on a middle plate workpiece, the slide carrier is moved to move the other middle plate workpiece to the bottom of the shrapnel assembly mechanism for shrapnel insertion. The operator takes out the assembled middle plate and positions the new aerial plate workpiece, so that uninterrupted assembly can be achieved, effectively improving work efficiency.

[0030] See also Figure 1-14As shown, the present invention relates to an automatic keyboard shrapnel assembly machine, comprising a machine platform 1, on which a slide carrier 2, a shrapnel material guide mechanism 3, a shrapnel assembly mechanism 4 and a paper tape recovery mechanism are provided. The slide carrier 2 is arranged on the top surface of the machine platform 1 and is used for positioning the middle plate, a bracket 10 is arranged on the top of the slide carrier 2, and a shrapnel assembly mechanism 4 is arranged on the top of the bracket 10. A shrapnel material guide mechanism 3 is arranged behind the shrapnel assembly mechanism 4, and a paper tape recovery mechanism is arranged on the rear side of the shrapnel material guide mechanism 3. After the shrapnel material carried on the paper tape passes through the shrapnel material guide mechanism 3, the paper tape is recovered by the paper tape recovery mechanism, and the shrapnel material tape enters the shrapnel assembly mechanism 4 to separate the shrapnel and the waste material tape, the waste material tape flows out through the shrapnel material guide mechanism 3, and the shrapnel is installed on the key position of the middle plate through the shrapnel assembly mechanism 4.

[0031] Preferably, the slide carrier 2 moves in the XY directions on the machine 1 through an X-axis moving mechanism (not shown in the figure) and a Y-axis moving mechanism (not shown in the figure). The X-axis moving mechanism is arranged on the machine 1, and the Y-axis moving mechanism is arranged on the X-axis moving mechanism. The slide carrier 2 is arranged on the Y-axis moving mechanism. It is common knowledge in the art that the X-axis moving mechanism and the Y-axis moving mechanism use the slide carrier 2 to move in the X and Y axis directions. The slider 422 slide rail transmission mechanism is commonly used in the art, so a detailed structural description is not given.

[0032] The slide carrier 2 is provided with two areas for placing the middle plate workpiece, and positioning wheels are provided around the middle plate workpiece area, and the middle plate is tightly fitted with the positioning wheels around the middle plate. It is common knowledge in the art that the middle plate workpiece area is fixed by the positioning wheels, but the spring pieces are often not installed accurately. Later, after many studies and analyses, the applicant found that during the assembly process, the middle plate is easy to loosen, so that the spring piece cannot be inserted accurately. The manufacturing process itself or the transportation process may cause the middle plate to deform and become uneven, so that one side of the middle plate will be tilted and loosened during the insertion process, making the spring piece installation inaccurate. The applicant conceived how to quickly install the middle plate workpiece area and quickly remove the middle plate. The applicant changed the positioning wheel on the rear side of the slide carrier 2 to a positioning wheel with a slot, and a quick chuck 21 is provided on the front side of the slide carrier 2. Figure 2 When the middle plate is placed in the middle plate workpiece area, one end of the middle plate is inserted into the positioning wheel with a slot, and the other end of the middle plate is fixed by pressing the quick chuck 21 to ensure that the middle plate is flat and that the spring assembly mechanism 4 can accurately and quickly assemble the spring. After the assembly is completed, you only need to pop up the quick chuck 21 and take out the middle plate with the spring inserted. The slide carrier 2 has two middle plate workpiece areas. When the middle plate workpiece on one area is inserted with a spring, the other area can be used by the operator to take and place the middle plate workpiece, so as to achieve uninterrupted work and improve work efficiency.

[0033] Preferably, the spring sheet material belt guide mechanism 3 includes a guide bracket 31, a spring sheet material tray 32, a material belt feed channel 33 and a waste belt discharge channel 34. The spring sheet material tray 32 is arranged on the guide bracket 31. The spring sheet material belt is led out from the spring sheet material tray and then bypasses the induction axis spring sheet assembly mechanism 4 for feeding. The spring sheet assembly mechanism 4 includes a frame 41. The frame 41 is arranged on the machine 1. The material belt feed channel 33 and the material belt guide groove 46 of the frame 41 are connected to each other. Corresponding to the material opening, one end of the waste belt discharge channel 34 is arranged next to the front end discharge port of the material belt guide groove of the frame 41, and the spring sheet material belt roll is installed in the spring sheet material tray 32, and one end of the spring sheet material belt is fed into the material belt guide groove of the frame 41 through the material belt feed channel 33, and moves forward under the push of the feeding mechanism 42. The waste belt with the cut spring sheet is guided to the waste belt discharge channel 34 and moved to the waste collection station, and a collection box can be placed at the waste collection station.

[0034] Preferably, the spring sheet assembly mechanism 4 includes a frame 41, on which a feeding mechanism 42, a positioning mechanism 43, a slicing mechanism 44 and a clamping mechanism 45 are provided. A material strip guide groove for moving the spring sheet material strip is provided in the frame 41, and the positioning mechanism 43 and the slicing mechanism 44 are arranged on both sides of the material strip guide groove opposite to each other. The feeding mechanism 42 is arranged behind the positioning mechanism 43 and the slicing mechanism 44, and the clamping mechanism 45 is arranged in front of the positioning mechanism 43 and the slicing mechanism 44. The feeding mechanism 42 drives the spring sheet material strip to move forward in the material strip guide groove, the positioning mechanism 43 positions the spring sheet material strip, the slicing mechanism 44 cuts off the spring sheet, and the clamping mechanism 45 clamps the spring sheet that has been cut off from the material strip and places it in the key position of the middle plate.

[0035] The feeding mechanism clamps the shrapnel material strip and transmits it forward, the shrapnel positioning mechanism positions the transmitted shrapnel material strip to facilitate the subsequent cutting of the shrapnel, the slicing mechanism can fully automatically cut the shrapnel so that the shrapnel can automatically detach from the shrapnel material strip, the shrapnel clamping mechanism can load the cut shrapnel into the key position of the middle plate, and the sliding table carrier makes the key position on the middle plate where the shrapnel needs to be installed be accurately located directly below the shrapnel grasping mechanism, ensuring that the shrapnel grasping mechanism can accurately and quickly assemble the shrapnel. At the same time, it realizes the integration of fully automatic loading, fully automatic feeding, fully automatic positioning, fully automatic cutting of shrapnel and fully automatic assembly for the shrapnel. The operation process is fully automated with a high degree of automation, which not only greatly reduces labor intensity and labor costs, but also achieves high assembly accuracy, high assembly efficiency and good assembly effect. It has a simple structure and is easy to operate.

[0036] Preferably, the feeding mechanism 42 includes a feeding cylinder 421, a slider 422, a transmission rod 423 and a guide block 424. The feeding cylinder 421 is arranged on the frame 41. The slider 422 moves on the frame 41 through a slide rail and is transmission-connected to the feeding cylinder 421. The transmission rod 423 is connected to the slider 422. A limiting groove is provided on the top of the slider 422. The guide block 424 is penetrated on the transmission rod 423 and rotatably arranged in the limiting groove. One end of the guide block 424 is in a right-angled triangle structure, and its right-angled side is on the side close to the slide carrier 2. When the right angle of the guide block 424 The angled end formed by the edge and the hypotenuse is clamped in the positioning hole of the spring sheet material belt. The feeding cylinder 421 pushes the slider 422 forward, and the guide block 424 moves with the slider 422 and drives the spring sheet material belt to move forward in the material belt guide groove. The limit groove limits the rotation angle of the guide block 424 and the force is transmitted to the spring sheet material belt by the right-angle edge of the guide block 424, so the guide block 424 is not easy to be separated from the positioning hole of the spring sheet material belt, and the spring sheet material belt is stably driven to move; when the feeding cylinder 421 drives the slider 422 to move backward, the hypotenuse of the guide block 424 makes it easier for the guide block 424 to be separated from the positioning hole and clamped in the next positioning hole. The guide block 424 will not rotate when the spring sheet material belt is moved forward. When the cylinder retracts, the guide block rotates forward (similar to the folding knife, but the guide block does not fold, and the angle is slightly rotated) and is separated from the positioning hole of the spring sheet material belt.

[0037] Preferably, the positioning mechanism 43 includes a positioning cylinder 431, a first transmission block 432, a second transmission block 433 and a positioning pin 434. The positioning cylinder 431 is arranged on the frame 41. The first transmission block 432 is connected to the positioning cylinder 431. The first transmission block 432 is provided with an oblique arc hole. The second transmission block 433 is passed through the arc hole by a pin shaft so as to be transmission-connected with the first transmission block 432. The positioning pin 434 is connected to the second transmission block 433. The positioning cylinder 431 drives the first transmission block 432 to move up and down, and drives the second transmission block 433 to move horizontally through the transmission cooperation between the pin shaft and the arc hole, so that the positioning pin 434 is inserted into the positioning hole of the spring sheet material belt to complete the positioning. After slicing, the positioning mechanism 43 resets the positioning pin 434. When the next spring sheet reaches the slicing mechanism 43, the positioning pin is inserted into the positioning hole of the spring sheet material belt again.

[0038] In the existing shrapnel machine, whether it is pushing shrapnel or positioning shrapnel, the corresponding mechanism directly acts on the shrapnel. Secondly, the shrapnel material belt is fed vertically downward along the shrapnel machine. During the pushing process, the shrapnel is easily deformed and the feeding is not smooth. In this embodiment, the shrapnel material belt includes a metal material belt carrying the shrapnel and the shrapnel. The feeding mechanism pushes the shrapnel material belt by acting on the metal material belt, and the positioning is also performed by the metal material belt, without directly acting on the shrapnel, and the shrapnel material belt is fed along the horizontal direction of the shrapnel machine. The shrapnel material tray 32, the feeding mechanism 42, and the positioning mechanism 43 are arranged in sequence along the horizontal direction of the shrapnel machine. The feeding process is relatively stable. The shrapnel material tray 32, the feeding mechanism 42, and the positioning mechanism 43 all act on the flat metal material belt carrying the shrapnel. The coordinated actions complete the feeding to the slicing mechanism 44 and the positioning of the shrapnel. The feeding is fast and smooth. Figure 8 It is a simple diagram, in which a spring is drawn at the position of the slicing mechanism 44 of the spring sheet material belt. In fact, the spring sheet is carried on the metal material belt from the spring sheet material tray 32 to the slicing mechanism 44. After the slicing mechanism 44 cuts off the spring sheet, the metal material belt becomes waste and flows out directly along the waste belt discharge channel 34.

[0039] Preferably, the slicing mechanism 44 includes a slicing cylinder 441 and a slicing tool 442. The slicing cylinder 441 is arranged on the frame 41 through a cylinder seat 443. The slicing tool 442 is guided and moved on the cylinder seat 443 through a tool seat 444 and is transmission-connected to the slicing cylinder 441. When the positioning mechanism 43 completes the positioning of the spring sheet material belt, the slicing cylinder 441 drives the tool seat 444 to move toward the spring sheet material belt, and the slicing tool 442 separates the spring sheet from the material belt.

[0040] Preferably, the clamping mechanism 45 includes a transverse movement mechanism 451, a lifting mechanism 452 and a clamping claw assembly 453. The transverse movement mechanism 451 is arranged on the frame 41, and the lifting mechanism 452 is arranged on the transverse movement mechanism 451. The clamping claw assembly 453 is connected to the lifting mechanism 452 by transmission. The clamping claw assembly 453 includes a finger cylinder and a clamping hand. The finger cylinder is connected to the lifting cylinder. The two clamping hands are connected to the finger cylinder by transmission. The clamping claw assembly 453 moves to the top of the cut shrapnel through the transverse movement mechanism 451, and the lifting mechanism 452 drives the clamping jaw assembly 453 down to the spring piece, and the finger cylinder drives the two clamping hands to move inwards relative to each other to clamp the spring piece, and then the lifting mechanism 452 drives the clamping jaw assembly 453 to rise, and the transverse movement mechanism 451 drives the clamping jaw assembly 453 to move to the middle plate workpiece of the slide carrier 2, and the lifting mechanism 452 drives the clamping jaw assembly 453 to descend, and the clamping jaw cylinder drives the two clamping hands to move outwards relative to each other. The clamping hands are L-shaped, and clamping the spring piece is more stable than the scissor-type structure clamping hands. The clamping hands release the spring piece, so that the spring piece is stuck in the key position of the middle plate workpiece.

[0041] Preferably, the paper tape recycling mechanism includes a paper tape receiving tray and a paper tape adjusting mechanism arranged at the feeding port of the paper tape receiving tray, the paper tape adjusting mechanism includes a support frame 71, a detection switch 74 is provided on one side of the support frame 71, a guide rod 72 is provided along the height direction of the support frame 71, an iron block 73 is slidably provided on the guide rod 72, the iron block 73 uses its own weight to drive the paper tape to move slowly downward, and after the iron block 73 falls to a certain height, a detection switch installed on the support frame 71 that is consistent with the falling height of the iron block 73 74 is blocked by the iron block 73. At this time, the light emitted by the transmitter is blocked by the iron block 73, and the receiver cannot receive the light signal. The detection switch 74 will send a preset signal to the paper tape receiving tray, and the paper tape receiving tray will start to receive the paper tape, slowing down the paper tape receiving speed and coordinating with the transmission speed of the shrapnel tape to avoid the tape breaking and shutdown. The traditional paper tape recovery mechanism does not have a paper tape adjustment mechanism. The paper tape receiving and the shrapnel tape discharge are not synchronized, resulting in tape breaking. The paper tape adjustment mechanism is used to coordinate the discharge, thereby avoiding the shrapnel tape breaking and shutdown.

[0042] The operation process of the keyboard spring automatic assembly machine is as follows: first, two middle plates are placed on the slide fixture, and the slide fixture can realize horizontal positioning and vertical positioning through the X-axis positioning module and the Y-axis positioning module respectively. The spring strip is led out from the spring strip material tray and then bypasses the sensing shaft for loading. The material strip can be detected by the sensing shaft. When the material strip is used up and the sensing shaft cannot detect the material strip, the insertion work is stopped to prevent empty insertion. The spring strip material strip enters the spring strip material guide mechanism 3. At this time, the paper tape carrying the spring strip material strip is recovered through the paper tape receiving tray, and the paper tape adjustment mechanism When the paper tape is detected, the paper tape receiving tray is driven to recycle the paper tape. The traditional paper tape receiving tray feeds the spring sheet material tape while recycling it, but the speeds of the two sides are inconsistent, which is easy to jam the machine. The paper tape adjustment mechanism is used to increase the span of the paper tape. After the paper tape is delayed for a certain length, the paper tape receiving tray recycles the paper tape to avoid stopping due to tape breakage. The spring sheet material tape is fed into the slicing mechanism 44 through the feeding mechanism 42. When feeding into the slicing mechanism 44, the positioning mechanism 43 positions the spring sheet material tape through the positioning pin, so as to facilitate the slicing mechanism 44 to slit the spring sheet material tape in the next step. Punching, the slicing mechanism 44 cuts off the spring piece from the spring piece material strip, and the clamping mechanism 45 is inserted laterally above the cutting knife mechanism to clamp the spring piece. The traditional clamping mechanism clamps vertically downward (i.e., falls vertically into the material), and the clamping mechanism cannot clamp the spring piece stably. The clamping mechanism of this embodiment clamps the material obliquely by the clamping hand (XY axis moves at the same time to form an oblique entry mode), the clamping mechanism clamps the spring piece stably, and then loads the spring piece into the middle plate, and the clamping mechanism resets to continue to clamp the next spring piece, and the material strip cut off from the spring piece is discharged and recycled through the waste belt discharge channel It integrates fully automatic loading, fully automatic feeding, fully automatic positioning, fully automatic spring clip cutting and fully automatic assembly. Its operation process is fully automated with a high degree of automation. It not only greatly reduces labor intensity and labor costs, but also achieves high assembly precision, high assembly efficiency and good assembly effect. It has a simple structure and is easy and quick to operate. It solves the problem that the spring clips for the middle plate are installed manually, which not only has high labor intensity and high labor costs, but also has poor installation effect, low installation efficiency and high installation cost.

[0043] Preferably, it further comprises an electric control device 5 , which is arranged on the machine platform 1 , and is electrically connected to each mechanism, and has a plurality of control buttons.

[0044] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
