[0021] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.
[0022] according to Figure 1 , 2 As shown in Figures 3, 4 and 5, a keyboard assembly device is proposed in this embodiment, including a machine table 1, a cantilever 3 is provided above the machine table 1, one end of the cantilever 3 is fixedly connected to a stand 2 arranged on one side of the machine table 1, a key shaft box 4 is provided at the other end of the cantilever 3, and a key shaft pressing plate 5 is provided at the lower end of the key shaft box 4; when the keyboard falls under the key shaft pressing plate 5, the key shaft pressing plate 5 will buckle the key shaft in the key shaft box 4 onto the keyboard.
[0023] A first adjustment plate 6 is provided below the key shaft pressure plate 5, the lower end of the first adjustment plate 6 is slidably connected to the upper end of the machine table 1, a second adjustment plate 9 is provided at the upper end of the first adjustment plate 6, the second adjustment plate 9 is slidably connected to the first adjustment plate 6, and a sliding drive assembly is provided at the connection between the first adjustment plate 6 and the machine table 1 and the second adjustment plate 9;
[0024] A placement slot 10 is provided at the upper end of the second adjustment plate 9, and tooling fixtures are provided on the two opposite sides of the placement slot 10. A push plate assembly and a material discharge notch are provided on the other two opposite sides of the placement slot 10, respectively. A material guide inclined plate is provided below the material discharge notch, and the material guide inclined plate is movably connected to the second adjustment plate 9. The keyboard to be assembled is placed in the placement slot 10, and the tooling fixture can fix the keyboard from both sides of the keyboard. The push plate assembly is arranged opposite to the material discharge notch. When the key shaft is installed, the push plate assembly can push the keyboard in the placement slot 10 outward to complete automatic unloading. The material guide inclined plate at the lower end of the material discharge notch can guide the keyboard when it is pushed outward, so that the keyboard can slide smoothly to the external storage rack or feeding equipment, and the unloading is stable and safe.
[0025] Specifically, the sliding drive assembly includes a first linear motor 7 laid between the first adjustment plate 6 and the machine 1 and a second linear motor 8 laid between the second adjustment plate 9 and the first adjustment plate 6. The stator of the first linear motor 7 is fixedly connected to the upper end of the machine 1, the mover of the first linear motor 7 is fixedly connected to the lower end of the first adjustment plate 6, the stator of the second linear motor 8 is fixedly connected to the upper end of the first adjustment plate 6, and the mover of the second linear motor 8 is fixedly connected to the lower end of the second adjustment plate 9. The first linear motor 7 and the second linear motor 8 are a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. In terms of structure, the linear motor can be regarded as a rotating motor cut radially and unfolded into a plane. It mainly consists of three parts: a stator, a mover and a support wheel. When the magnetic field generated by the motor stator coil is energized, it acts on the magnetic steel in the iron core to generate an electromotive force and form a rotating magnetic field. When a load is connected to the stator, it is generally a permanent magnet. Then, the current passes through the load circuit to make the motor run. Here, the first linear motor 7 and the second linear motor 8 are vertically staggered, and are used to adjust the position of the keyboard on the second adjustment plate 9 on the X-axis and the Y-axis respectively.
[0026] The keyboard to be assembled is placed in the placement groove 10, and the fixture can fix the keyboard from both sides of the keyboard. The fixture includes two second electric push rods 13, which are respectively installed on both sides of the second adjustment plate 9. The output ends of the second electric push rods 13 penetrate into the placement groove 10 and are fixedly connected to the clamping plate 14 provided in the placement groove 10. There are two clamping plates 14 in the placement groove 10. When fixing the keyboard, the two clamping plates 14 are pushed by the second electric push rods 13, and the two clamping plates 14 can clamp the keyboard when they are closed.
[0027] The push plate assembly is arranged opposite to the discharge notch, and is used to push the keyboard in the placement slot 10 outward when the key shaft is installed. The push plate assembly includes a first electric push rod 11 and a push plate 12. The first electric push rod 11 is installed on the side of the second adjustment plate 9 away from the discharge notch, and the output end of the first electric push rod 11 is fixedly connected to the push plate 12 arranged in the placement slot 10. The push plate 12 is staggered with the two clamping plates 14. After the two clamping plates 14 contact and fix the keyboard, the first electric push rod 11 will push the push plate 12 toward the discharge notch and push the keyboard out of the discharge notch.
[0028] The keyboard is guided by the guide ramp to improve the stability of the keyboard during unloading. The guide ramp includes a guide ramp 16. One end of the guide ramp 16 is rotatably connected to the second adjustment plate 9 through a movable pin 15. A limit slot 20 is provided at the lower end of the guide ramp 16. A slider 19 is provided in the limit slot 20. The slider 19 is slidably connected to the limit slot 20. The slider 19 is rotatably connected to the horizontal push component provided in the second adjustment plate 9. The horizontal push component pushes the slider 19 horizontally. The slider 19 slides along the limit slot 20 and pushes the guide ramp 16. The guide ramp 16 rotates with the movable pin 15 as the center, and then adjusts the angle between the guide ramp 16 and the second adjustment plate 9, so as to match the shelf below the second adjustment plate 9 that is not at a high position.
[0029] Specifically, the push plate adjustment part includes a third electric push rod 18, which is installed in the installation cavity 17 opened on the inner side of the second adjustment plate 9. The output end of the third electric push rod 18 passes through the installation cavity 17 and is rotatably connected to the slider 19. The horizontal push of the slider 19 is controlled by the third electric push rod 18, and the third electric push rod 18 can also be replaced by a linear push component such as a hydraulic push rod and a pneumatic push rod.
[0030] It should be noted that the slider 19 is a T-shaped slider, and the limiting groove 20 is a T-shaped groove that matches the T-shaped slider. The advantage of this arrangement is that when the slider 19 slides along the limiting groove 20, it will not fall out of the limiting groove 20, and the cooperation between the slider 19 and the limiting groove 20 will also be more stable.
[0031] Working principle: the keyboard to be assembled is placed in the placement slot 10, the tooling fixture can fix the keyboard from both sides of the keyboard, the push plate assembly is arranged opposite to the discharge notch, and when the key shaft is installed, the push plate assembly can push the keyboard in the placement slot 10 outward to complete automatic unloading. The guide inclined plate at the lower end of the discharge notch can guide the keyboard when it is pushed outward, so that the keyboard can slide smoothly to the external holding rack or feeding equipment, and the unloading is stable and safe.
