Description

Technical Field

[0001] The utility model discloses a mounting device for conductive rubber buttons of electronic piano keys, belonging to the technical field of electronic musical instruments. Background Art

[0002] With the popularity of electric pianos, more and more families are using electric pianos. The conductive glue buttons on the keys of the electric pianos are switch buttons that trigger the sound of the PCB board. The conductive glue buttons are de-energized by pressing the keys to connect the circuit on the PCB board, thereby realizing the sound of the electric piano. The existing conductive glue buttons on the keys of the electric pianos are installed manually. First, the conductive glue buttons are placed on the corresponding positions of the PCB board, and then the limit pins of the conductive glue buttons are pulled over from the other side of the PCB board by tweezers to achieve stable installation. However, this operation not only leads to low installation efficiency of the conductive glue buttons, but also manual assembly is prone to forgetting or carelessness, resulting in some of the limit pins of the conductive glue buttons not being completely and firmly assembled on the PCB board. The conductive glue buttons that are not installed in place may be offset or fall off after long-term use, thereby causing the keys of the electric piano to malfunction, thereby affecting the use of the electric piano. Therefore, in order to solve this problem, a new solution needs to be proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0024] A mounting device for conductive rubber buttons of electronic piano keys comprises a frame, the frame comprises a top plate 1, a bottom plate 2 and side plates, the side plates are arranged on both sides of the top plate 1 and the bottom plate 2 by bolts, and a cylinder 3 is fixed on the top of the top plate 1, the piston end of the cylinder 3 faces downward and penetrates the top plate 1, and a pressing plate 4 is fixed on the piston end by bolts, the length direction of the pressing plate 4 is consistent with the length direction of the top plate 1, so the extension and contraction of the piston end of the cylinder 3 can drive the pressing plate 4 to move up and down; two stabilizing rods 15 are arranged on the pressing plate 4, which are symmetrically arranged on both sides of the pressing plate 4 and fixed to the top of the pressing plate 4 by bolts, and the stabilizing rod 15 penetrates the top plate 1, and a sliding sleeve 16 is arranged on the top plate 1, the sliding sleeve 16 is fixed to the top plate 1, and is sleeved on the stabilizing rod 15, so the stabilizing rod 15 will move with the movement of the pressing plate 4, and under the action of the sliding sleeve 16 and the stabilizing rod 15, the pressing plate 4 can remain stable when moving.

[0025] A supporting plate 5 is provided on the bottom plate 2, and a plurality of PCB boards 6 are placed on the supporting plate 5. Two front and rear positioning grooves 20 are provided on the top of the supporting plate 5. The PCB board 6 is placed on the positioning groove 20, and the specific shape of the positioning groove 20 can be customized according to the PCB board 6 to be processed; a plurality of conductive rubber buttons 7 are provided on the PCB board 6, and four limiting foot posts 8 are provided at the bottom of each conductive rubber button 7. The four limiting foot posts 8 are respectively located at the four corners of the conductive rubber button 7, and the conductive rubber button 7 can be arranged individually or in a row. The PCB board 6 is provided with foot post holes 9 that match the limiting foot posts 8. By passing the limiting foot posts 8 through the foot post holes 9 The conductive rubber button 7 can be stably installed. In the existing manual installation, since the pressure surface of the operator's fingers is large and the force direction and strength are not uniform, if the limiting foot 8 is pressed downward from the top into the foot hole 9, the limiting foot 8 will be squeezed and deformed and shortened due to the uneven large pressure surface force, so that the diameter becomes wider and presses on the top surface of the foot hole 9, and cannot be completely embedded in the foot hole 9. Therefore, tweezers are actually used to clamp the limiting foot 8 from the other side and pull it. At this time, the stretched limiting foot 8 will also be deformed, but the diameter is narrowed, so that it can be easily embedded in the foot hole 9. However, this installation method is time-consuming, labor-intensive and inefficient.

[0026] A pressing plate 10 is fixed to the bottom of the pressing plate 4 by bolts, and a plurality of ejector pins 11 are arranged at the bottom of the pressing plate 10, and the ejector pins 11 correspond to the positions of the limiting foot posts 8. Therefore, when the pressing plate 4 is driven downward by the cylinder 3, the pressing plate 10 is also driven to move downward together. Since the ejector pins 11 correspond to the positions of the limiting foot posts 8, and the pressure application surface of the ejector pins 11 is relatively small, and the force application direction and force are uniform, under the extrusion of the ejector pins 11, the limiting foot posts 8 can also be ensured to be fully embedded in the foot post holes 9, thereby realizing the stable installation of the conductive rubber button 7; the pressing plate 10 is provided with clearance grooves 19 corresponding to the number and positions of the conductive rubber buttons 7, and the clearance grooves 19 can make the tops of the conductive rubber buttons 7 embedded therein when the conductive rubber buttons 7 are squeezed, thereby ensuring the extrusion of the conductive rubber buttons 7 by the ejector pins 11.

[0027] Two slide rails 12 are arranged on the bottom plate 2, and a slider 13 matching with the slide rails 12 is fixed to the bottom of the supporting plate 5. The slider 13 is slidably connected with the slide rails 12, so that the supporting plate 5 can move horizontally forward or backward under the cooperation of the two; blocks 14 are arranged at both ends of the slide rails 12, and the blocks 14 can limit the movement range of the supporting plate 5 to ensure that the supporting plate 5 will not separate from the bottom plate 2; rollers 21 are arranged at the bottom of the supporting plate 5, and the rollers 21 can make the horizontal movement of the supporting plate 5 smoother and easier to operate; a handle 22 is arranged on the front side of the supporting plate 5, and the operator can use the handle to manually move the supporting plate 5 22's push and pull; an in-position sensing column 17 is provided at the bottom of the supporting plate 5. When the supporting plate 5 is pushed to the bottom of the pressing plate 10, the magnetic switch provided in the bottom plate 2 will sense the in-position sensing column 17. Only when the magnetic switch senses the in-position sensing column 17 can the cylinder 3 operate, thereby ensuring the accuracy of the pressing plate 10 when it is pressed down. The magnetic switch can use existing products; safety protection switches 18 are provided at both ends of the bottom plate 2. Only when the operator presses the two safety protection switches 18 with both hands at the same time, the cylinder 3 will be started, and it needs to be pressed continuously, thereby ensuring the safety of the operator and preventing his hands from being pressed.

[0028] Working principle of the utility model: When in use, the operator can first pull out the support plate 5, and then align the PCB board 6 to be processed with the positioning groove 20 and put it in, and then place the conductive rubber button 7 to be installed on the PCB board 6. When placing, just slightly embed the head of the limit foot column 8 into the foot column hole 9, which mainly plays a positioning role, and then push the support plate 5 back inward until the magnetic switch senses the induction column 17 in place. A prompt light can be set on the bracket to let the operator distinguish. At this time, the staff presses the safety protection switch 1 on both sides of the bottom plate 2 with both hands. 8, the cylinder 3 will start and drive the pressing plate 4 and the pressing plate 10 to move downward and press the conductive glue button 7. Under the pressure of the ejector pin 11, the limiting foot 8 will be completely embedded in the foot hole 9 to achieve semi-automatic installation. Finally, the operator only needs to pull the supporting plate 5 outward again and remove the PCB board 6 with the conductive glue button 7 installed. Compared with the existing manual installation, the device not only increases the installation efficiency of the conductive glue button 7 and saves labor costs, but also ensures that each conductive glue button 7 is firmly fixed on the PCB board 6, avoiding the incomplete installation that may be caused by manual installation.
