Description

Dispenser with rotary menu selection

The present invention relates to a dispenser having a rotary menu selection function, and more particularly, a single rotation and push with a forced braking function instead of a plurality of push button-type menu selection buttons and numerical input buttons installed in the front of the dispenser. By installing an operation type menu selection and numerical input device and a touch operation type display, even an unskilled operator can easily select and input menus and values, and significantly reduce the probability of erroneous operation or misselection and incorrect input. Not only can the reliability of the product be greatly improved, but also the production yield of electric and electronic products manufactured using this can be greatly increased, and the production of electric and electronic products manufactured using a dispenser by preventing unnecessary economic/time loss. The present invention relates to a dispenser having a rotary menu selection function invented so as to significantly reduce the cost itself and increase the appearance of the dispenser to greatly increase the marketability of the dispenser itself.

In recent years, in response to the trend of miniaturization of electric and electronic products, there is a trend of miniaturization, high density, and diversification of electronic products.

Accordingly, surface mounting technology has been commercialized as a base applied to the assembly production of printed circuit boards (PCBs) applied to such electric and electronic products.

In such surface mounting, it is essential to apply an adhesive to the PCB on which the surface-mounted component is located by a dispensing process.

In addition, a dispensing process is also required for mounting parts such as a camera module housing of a mobile phone.

The dispenser for executing this dispensing process moves the X-axis to the Y-axis for dispensing while the head is mounted on a robot unit that can move freely in the X-axis-Y-axis, respectively → Z-axis descending → Nozzle. Dispensing by means of dispensing by dispensing the adhesive by repetitive operation of increasing the Z-axis.

Such a dispenser operates the dispenser by connecting the teaching pendant to the robot unit using a wired cable, bringing the main program stored in the control unit of the robot unit into the teaching pendant, making some modifications according to the product.

In addition, the dispenser requires a plurality of menu selection buttons for each menu in order to select a menu for the liquid to be used. In addition, 0 to enter the setting value for the pressure or time considering the viscosity of the liquid. A number input button that can directly input up to 9 is required, and such menu selection buttons and number input buttons need to be placed on the front panel of the dispenser for convenience of operation.

However, although there are dozens of menus for liquids, most of the conventional dispensers adopt push buttons including the dozens of menu selection buttons and number input buttons described above, so push buttons occupy most of the front panel of the dispenser. Not only is it not beautiful, it is also very difficult to select and manipulate any of these.

In addition, because the front panel of the dispenser is limited in its area, the menu name for each menu selection button cannot be expressed in detail, and only a simple name is displayed. Therefore, the operator of the dispenser does not fully understand the product commercial manual. Since it is not clear what the name written around the menu selection button of is not clearly known, the unskilled dispenser operator has a lot of difficulty when selecting a menu, as well as a high probability of misoperation. High (that is, low production yield) of the product increases the production cost and leads to unnecessary economic and time loss.

At this time, the case 441 of the components of the shaft return means 44, the bottom surface in a state in which the cylindrical body 441a is fitted through the cylindrical body passage hole 412a formed on the upper portion of the return means installation plate 412 In the part, a flange 441c provided with a shaft through hole 441b in the center is integrally installed, and in such a case 441, a flange 441c provided on the front surface of the cylindrical body 441a is returned. It has a form fixed to the front of the means installation plate 412 and is coupled in a form that surrounds the front end of the shaft 42 within the base frame 41, and the spring of the shaft 42 is on the rear surface of the flange 441c. The support protrusion 421 has a shape in which the front surface is hung, and serves to prevent the guide bush 442 and the coil spring 443 from being seen from the outside.

In addition, the guide bush 442 has a cylindrical shape having an outer diameter smaller than the inner diameter of the cylindrical body 441a of the case 441 and a larger inner diameter than the outer surface of the spring support protrusion 421 of the shaft 42 As such, the guide bush 442 is installed in a form surrounding the shaft 42 in the cylindrical body 441a and is compressed when the shaft 42 is retracted through the operation of pressing the knob 43 A part of (443) performs a function to prevent deformation in advance such as bending to one side or distorting itself.

In addition, the coil spring 443, in a state coupled to the outside of the polygonal fixing portion 422 of the shaft 42, the front one end is supported on the rear surface of the spring support protrusion 421 of the shaft 42, the other rear end Has a form installed to be supported on the front surface of the intermediate support and fixing plate 45 fixedly installed on the rear surface of the cylindrical body 441a of the case 441.

Such coil spring 443 exerts its own elastic force between the rear surface of the spring support protrusion 421 of the shaft 42 and the front surface of the intermediate support and fixing plate 45, so that the rear end of the shaft 42 is usually It maintains a state separated from the switch 48, and generates an elastic force for restoration the moment the operator presses the knob 43 and releases the hand, thereby performing a function of automatically returning the shaft 42 to its original position.

In addition, the intermediate support and fixing plate 45 has a rectangular or rectangular plate shape, and the shaft through hole 451 is formed to have an inner diameter larger than the outer diameter of the polygonal fixing portion 422 of the shaft 42 in the upper portion. It has a form that is fixedly installed in the horizontal direction at the rear portion of the shaft original return means 44 in a state coupled to the shaft 42, the support function of the coil spring 443 and the encoder 46 to be described later. Among the components, the optical sensor 463 functions to be fixed.

In addition, the encoder 46 is composed of a rotating plate 461 and an optical sensor 463, of which the rotating plate 461 has a plurality of slits 461a formed at equal intervals along the outer edge, and a polygonal shape at the center Since the shaft fixing hole 461b is formed, it forms a right angle to the shaft 42 through the polygonal shaft fixing hole 461b and is fixedly installed outside the polygon fixing part 422.

At this time, the shaft fixing hole formed in the center of the rotating plate 461 has a polygonal shape such as a square, hexagonal or octagonal shape corresponding to the shape of the polygonal fixing part 422 of the shaft 42, so that the knob 43 And when the shaft 42 is rotated in a clockwise or counterclockwise direction, the rotating plate 461 together with the shaft 42 rotates in a clockwise or counterclockwise direction, and the knob 43 is pressed by the operator, so that the shaft 42 When is pushed toward the rear part, the rotating plate 461 does not move from its current position, and only the shaft 42 moves backward through the polygonal shaft fixing hole 461b formed in the center of the rotating plate 461.

In addition, the optical sensor 463 basically receives the light-emitting element 463a that is lit in response to the output signal of the control unit 30, and transmits the light to the control unit 30 by receiving the light generated by the light-emitting element 463a. A light-receiving element 463b is provided, and the light-emitting element 463a and the light-receiving element 463b are installed to face each other on the inside of both wings of the sensor fixture 462 having a "U" shape with a front end. And the light-emitting element 463a and the light-receiving element 463b are respectively disposed from both sides of the rotating plate 461 toward the slit direction, and are fixedly installed on one side of the rear surface of the intermediate support and fixing plate 45 respectively. Has.

The encoder 46 having such a configuration emits light passing through the slits 461a when the rotating plate 461 is rotated due to the rotation of the knob 43 and the shaft 42 clockwise or counterclockwise by the operator. The light-receiving device 463b receives the light from the device 463a in real time in the form of a pulse, and transmits the light to the controller 30.

Therefore, the control unit 30 receives the output signal of the light-receiving sensor 463 inputted in real time from the encoder 46 and continues to receive the input, and the amount of change in the rotation angle of the shaft 42 through the analysis program previously inputted in itself. If the operator selects the menu selection mode through the touch of the display 60, it is compared with the menu data of the previously input liquids, the operator recognizes which menu is the desired menu, and selects the numerical input mode. In the case, it is determined exactly what value to input, and when the text switch 48, which will be described later, is "on", the menu and value at that time are recognized as the final menu and value, and the liquid discharge amount through the nozzle is controlled ( That is, the liquid discharge amount is controlled through the opening and closing time of the nozzle and the discharge pressure of the liquid).

In addition, while the control unit 30 continues to calculate the amount of change in the rotation angle of the shaft 42 using the output signal of the encoder 46 as described above, menus in which the rotation angle of the shaft 42 is previously inputted within itself. It is judged whether the end point menu or the start point menu is removed, and whether the number's end and start limit points are exceeded, and if either the end menu or the start point menu has exceeded the limit point, or the end and start limit points of the number have been exceeded. When it is determined, the rotation in the corresponding direction is forcibly stopped through the clockwise or counterclockwise rotation stopping means 47 to be described later, so that the operator cannot rotate any more in the corresponding direction through the knob 43.

On the other hand, the clockwise or counterclockwise rotation stopping means 47 is braking by compressing a brake shoe (not shown) to a brake disc (not shown) fixedly installed on the shaft 42 using electromagnetic force. It is composed of an electromagnetic brake or the like, and has a form fixedly installed on the front of the rotation restraining means installation plate 413 of the base frame 41 in a form surrounding the rear part of the shaft 42.

Such clockwise or counterclockwise rotation restraining means 47, when the operator rotates the shaft 42 clockwise or counterclockwise through the knob 43, and selects a menu or inputs a value, the end point or the start point ( That is, when the limit point of any one of the final menu or the start point menu or the end and start limit of a number) is exceeded, the drive signal output from the control unit 30 is input and the shaft 42 is sent to the shaft 42 by using an electromagnetic force. It performs a function of automatically stopping the rotation of the shaft 42 by compressing the brake shoe on the fixedly installed brake disk.

On the other hand, the shaft torsion detection means 50, has a form consisting of the first and second optical laser reflective toothed rotating plates 51 and 52 and the first and second displacement sensors 53 and 54, A displacement sensor fixing plate 414 installed in a length and vertical direction from one side of the bottom surface of the base frame 41, and a front part of the shaft return means 44 at the polygonal fixing part 422 of the shaft 42 and an encoder (46) has a form installed between the rear part.

Such shaft torsion detection means 50 is a shaft detected through an encoder 46 while the operator rotates the shaft 42 clockwise or counterclockwise through the knob 43 and selects or inputs menus and values. The rotation of the shaft 42 is forcibly stopped by the control unit 30 through a clockwise or counterclockwise rotation stopping means 47 due to the rotation angle of 42 deviating from the final or starting point of the menus or values. In this state, the flexible shaft 42 is twisted due to the operator forcibly rotating the shaft 42 in the opposite direction through the knob 43, so that the front and rear phase difference of the shaft 42 is more than a predetermined phase difference. When this occurs, the control unit 30 recognizes this, and performs a function of automatically releasing the braking function of the clockwise or counterclockwise rotation stopping means 47.

At this time, among the components of the shaft torsion detecting means 50, the first and second sawtoothed rotating plates 51 and 52 for optical laser reflection are formed through the polygonal shaft through holes 511 and 521 formed in the center. Among the polygonal fixing portions 422 of the shaft 42, a front portion of the shaft return means 44 and a rear portion of the encoder 46 are respectively installed.

The first and second sawtooth-shaped rotating plates 51 and 52 for optical laser reflection are normally rotated when the operator rotates in response to the rotation of the shaft 42 through the knob 43, and the first And the optical laser generated by the second displacement sensors 53 and 54 is reflected in the form of pulses toward the first and second displacement sensors 53 and 54, thereby causing the distortion of the shaft 42 by the controller 30. The first and second displacement sensors 53 and 54 detect the occurrence of the front and rear phase difference.

In addition, the first and second displacement sensors 53 and 54 are arranged so that the optical laser irradiation and light receiving portions face the side surfaces of the first and second optical laser reflection toothed rotating plates 51 and 52, respectively. In this state, the displacement sensor fixing plate 414 of the base frame 41 is fixedly installed in front and rear portions, respectively.

The first and second displacement sensors 53 and 54 are controlled by the control unit 30 to provide the side surfaces of the first and second optical laser reflection toothed rotating plates 51 and 52, that is, the teeth. When the first and second optical laser reflection sawtooth rotating plates 51 and 52 rotate, the light reflected from the inclined surface of the sawtooth is received in real time and transmitted to the controller 30. The giving function is performed.

In such a first and second displacement sensor 53 and 54, an operator in a normal time in which the clockwise or counterclockwise rotation stopping means 47 is not operated, the shaft 42 and the first and the first and the first and second displacement sensors through the knob 43 When rotating the second optical laser reflective toothed rotating plates 51 and 52, the shaft 42 rotates normally without being distorted, so there is no front and rear phase difference, so the first and second displacement sensors 53 ( 54) has a shape with almost no phase difference in the pulse of the optical laser.

However, in the state that the rotation of the shaft 42 is forcibly stopped through the clockwise or counterclockwise rotation stopping means 47, the operator forcibly forces the shaft 42 in the opposite direction through the knob 43. When it is rotated, the flexible shaft 42 having the rear end braking by the clockwise or counterclockwise rotation stopping means 47 is twisted using the braking point of the rear part as a starting point, so that the front part of the shaft 42 and the The phase difference between the pulse signals detected by the first and second displacement sensors 53 and 54 respectively located at the rear portion is inevitably generated.

Therefore, the phase difference of the pulse signals detected by the control unit 30 through the first and second displacement sensors 53 and 54, respectively, that is, the front and rear phase differences of the shaft 42 are determined at an angle (for example, ±2 to 3 degrees) or more, recognizes that the operator wants to rotate the shaft in the opposite direction to the previous direction, and automatically activates the braking function of the clockwise or counterclockwise rotation stopping means (47) previously operating. Since it is released, the shaft 42 itself rotates freely in a direction corresponding to the will of the operator, and a menu selection or numerical value can be input.

On the other hand, the tact switch 48 is fixedly installed on the front of the switch fixing plate 49 installed on the rear surface of the rotation stopping means installation plate 413, and the operator completes the selection of a menu or input of a value, and the knob When the shaft 42 is retracted by pressing (43), an "on" signal is generated to the control unit 30 to allow the control unit 30 to recognize which menu or value is the last selected or inputted menu or value. And performs a function that allows final confirmation.

Therefore, even an unskilled operator can simply and accurately operate only one menu selection and numerical input device to select and input desired menus and values, and significantly reduce the probability of misselection and incorrect input due to incorrect operation of menu selection and numerical input devices. As it can be reduced, the reliability according to the function of the dispenser itself can be greatly improved, as well as the production yield of electric and electronic products manufactured using this can be greatly increased, and unnecessary economic/time loss can be prevented. The production cost of electric and electronic products manufactured by using can be greatly reduced, and the appearance of the dispenser can be increased, thereby greatly increasing the marketability of the dispenser itself.
