Description

  The present invention relates to a laser pointer. Specifically, the present invention relates to a laser pointer attached to a nozzle holder of a cleaning machine.

  In the cleaning machine, the nozzle injection position (position information of the object to be cleaned) is information that is most necessary for cleaning and / or drying the workpiece. This defect in the injection position requires time for cleaning and / or drying the workpiece, and the quality is inferior. Moreover, if the situation where the injection position is defective is not solved quickly, the above-described quality deterioration and product defects frequently occur, which becomes a serious problem. In particular, it is almost impossible for in-house and other engineers (assumed to be engineers) to travel on a business trip from a manufacturer of a washing machine in a remote location or overseas. ing.

  Conventionally, a laser pointer that captures (as information) position information of an object to be cleaned of a nozzle that cleans and / or dries a perforation inner wall and / or inner bottom of a workpiece intended by the present invention, and this laser No “washing machine provided with a control unit that can use the position information of the object to be cleaned by the pointer” is found. However, in the field of washing machines, there is an invention of an apparatus for cleaning a mold with a laser. For example, it is Unexamined-Japanese-Patent No. 11-99524. However, the present invention is cleaning by laser, and is not a structure for detecting position information of an object to be cleaned by a nozzle. On the other hand, regarding laser pointers, there is an information processing apparatus capable of intuitively performing an operation input on a projected image using a laser pointer. For example, it is Unexamined-Japanese-Patent No. 2015-14882. It is not the structure which detects the injection position of a nozzle as information mentioned above.

  A conventional laser pointer is a combination of a cylindrical main body, a light source and a lens built in the main body, as described in JP-A-2001-206686, for example. It is a structure to be attached to. Therefore, it is not a structure that can be freely and easily attached / detached, but there are problems such as a limited field of use and the need for labor when attaching / detaching.

  In the prior art and Documents 1 and 2, setting, changing, or adjusting the position information of the object to be cleaned of the nozzle (position information of the object to be cleaned) is, as a rule, based on manpower and empirical rules. It is. Therefore, in the case where the position information of the object to be cleaned is defective (collision of external factors to the nozzle, inadequate maintenance management, lack of experience, or being out of position due to replacement, failure), the above-mentioned As described above, it takes time to clean and / or dry the workpiece, and the quality is inferior.

  The present invention avoids such a situation, and features and benefits are as follows. The feature is that “the accuracy of the positional information of the object to be cleaned of the nozzle can be ensured, the time for cleaning and / or drying of the workpiece can be shortened, and the product quality can be eliminated along with the quality deterioration”. In addition, the benefit is that, in the case of an emergency in the case of a remote location from a washing machine manufacturer or overseas, for example, a personal computer, a telephone, or other communication means is used to give instructions to the party, and this party controls The position information of the object to be cleaned of the nozzle can be corrected by itself by using the section, and an accurate injection position can be secured, so that the engineer of the cleaning machine manufacturer does not have to bother to go on a business trip.

  The present invention has been made under the circumstances described above, and provides a laser pointer that can improve convenience.

According to the present invention, in the case of an emergency in the case of a remote place from a washing machine manufacturer or overseas, for example, a personal computer, a telephone, or other communication means is used to give an instruction to the party, and this party uses the control unit. In addition, the position information of the object to be cleaned of the nozzle can be corrected by oneself to ensure an accurate injection position, thus eliminating the need for the engineer of the cleaning machine maker to go on a business trip. Further, there is an advantage that “the laser pointer can be attached in an optimum state when being attached to the nozzle holder of the washing machine”. Furthermore, “providing the first and second screw portions makes it possible to handle at least the diameters of the screw portions on the inner peripheral surfaces of the two nozzle holders”.
As a result, the convenience of the laser pointer attached to the nozzle holder of the washing machine can be improved.

In FIGS. 1-1 and 1-2, a laser pointer A attached to a nozzle holder 10 to be described later has the following structure. The laser pointer A includes a cylindrical main body case 1 having an opening 1a, a large first screw portion 100 and a small first screw portion provided so as to be arranged in the central portion of the outer peripheral surface of the main body case 1 in the axial direction X. Two screw portions 101, anti-slip means 102 made of slits, irregularities, satin, etc. provided on the outer peripheral opening side, and arranged sequentially from the opening 1a of the main body case 1 to the buttocks 1b in the axial direction X, and The built-in cross-character output part 2, the convex lens 3, the excitation light generator 5, the power source 6 for the excitation light generator, and the lens frame 7 are main components.
The outer peripheral surfaces of the first screw portion 100 and the second screw portion 101 are constituted by male screw surfaces. The large first screw portion 100 is formed such that the outer peripheral surface thereof such as a screw thread has a larger diameter than the outer peripheral surface of the small second screw portion 101 such as a screw thread.
The cross-shaped output part 2 and the convex lens 3 are fitted and accommodated in the lens frame 7 and are fixedly secured inside the axial direction X from the opening 1a of the main body case 1 with a set screw. Further, the excitation light generator 5 is fixed from the central side in the axial direction X of the main body case 1 to the part side (rear end side) of the buttocks 1b. Therefore, when a switch (not shown) is turned on, the laser light emitted from the excitation light generator 5 is converted into a harmonic laser light, and then converged by the convex lens 3 and irradiated from the cross output part 2 to the outside. The cross-shaped focal point is the position information of the workpiece W, and becomes the ejection position of the nozzle 13 (target position of the nozzle 13) described later. The cross-shaped output part 2 is an optical system part that changes the spot light from the convex lens 3 into a cross-shaped line as shown in FIG. 3-2-2. There is a feature that can accurately capture the central portion (part) and the peripheral portion. That is, the injection point can be ascertained reliably and promptly by irradiating the center of the injection point with a point and the periphery of the injection point with a cross-character line.

  The 1st screw part 100 and the 2nd screw part 101 are provided in order to be able to respond to the size of the diameter of screw part 1000 of the inner skin of nozzle holder 10 mentioned below. In this example, as shown in FIG. 3-2, when the first screw portion 100 is large, the screw portion 1000 on the inner peripheral surface of the nozzle holder 10 is large enough to be screwed with the first screw portion 100. Is formed. On the other hand, when the first screw portion 100 is small, the screw portion 1000 (female screw surface) on the inner peripheral surface of the nozzle holder 10 is formed in a size that allows the second screw portion 101 to be screwed together. Accordingly, the first screw portion 100 and the second screw portion 101 (male screw) of the laser pointer A can be adapted to the size of the screw portion 1000 (female screw) of the nozzle holder 10.

As shown in FIGS. 3-1 to 3-2-2, the cleaning machine to which the laser pointer A is attached includes a nozzle holder 10 having a screw portion 1000 on the inner peripheral surface, and an arm that supports the nozzle holder 10. 11, a mechanism for swinging the arm 11, and a work support 12.
The nozzle holder 10 is attached with either a laser pointer A that emits laser light and a nozzle 13 that ejects cleaning water or dry air. When the laser pointer A is attached to the nozzle holder 10, the laser light from the laser pointer A is, for example, a hole W 3 of the workpiece W installed on the workpiece support 12 that is rotated by the motor 1200. The inner wall W1 and bottom W2 of W3 are irradiated.
The workpiece support 12 rotates the workpiece W fixed to the workpiece support 12 based on the rotation of the rotation shaft of the motor 1200. Therefore, the work W fixed to the work support 12 rotates, and laser light is individually emitted from the laser pointer A to each of the inner wall W1 and the bottom W2, and each irradiation position as a target is This is transmitted to the control unit 21 (teaching). Such irradiation and transmission work are performed individually and accurately at each position of the inner wall W1 and the bottom W2 (inner bottom) and at all the positions where the arm 11 swings. Each irradiation position is memorize | stored in the control part 21 as a target of numerical control by the means 20 (teaching means).
In the present embodiment, the arm 11 performs a swing operation. However, it is not limited to this. For example, the arm 11 may not perform a swing operation. When the arm 11 has a structure that does not perform a swing operation, for example, the nozzle holder 10 at the tip (the nozzle holder 10 includes a threaded portion 1000 on the inner peripheral surface) rotates 360 ° via a universal joint, And it is configured to swing freely.
R in the figure indicates a battery of the excitation light generator 5.

  Next, an example of a teaching method for teaching the injection position of the nozzle 13 for cleaning and drying will be described. FIG. 3-2-1 shows an irradiation position of the laser pointer A at any location on the inner wall W1 or bottom W2 of the hole W3 (working hole) of the workpiece W (the irradiation position is the jet of the nozzle 13 during cleaning and drying). It shows the situation of recognizing the same position as the position). The copying unit 20 (teaching device) performs teaching and records the irradiation position of the laser pointer A in the storage unit of the control unit 21. This is, for example, an operation for specifying an injection position in an operation of cleaning and drying. For example, the laser pointer A irradiates each point of the hole W3 (perforation) at a pinpoint with a crossed focus. Each irradiation position is a target of the nozzle 13 (position information of a hole W3 of the work W to be described later) in the cleaning and drying operation, and the target is numerically transferred to the control unit 21 by the copying means 20 by teaching. It is stored as a control target. In such an operation by irradiation and teaching, the movement of the nozzle 13 (including the injection direction and / or the injection force) required for cleaning and drying the workpiece W is recorded (as a target). . Thus, teaching by the copying unit 20 (teaching device) is completed.

Next, operations for cleaning and drying will be described. Based on the results of the teaching, as shown in FIG. 3-2-2, the cleaning water (chemical solution, tap water, recycled chemical solution, and the like from the nozzle 13 toward the irradiation position of the laser beam (specified injection position), and Cleaning is performed by spraying treated water such as recycled water, and foreign matters are removed from the holes W3. Next, the processing water is scattered by jetting air from the nozzle 13, the hole W3 is dried, and the entire workpiece W is dried. For example, each position of the hole W3 is, for example, in a pinpoint manner toward each injection position (laser light irradiation position) on the basis of the numerical control target recorded in the control unit 21. Washing water and drying air are further sprayed to wash and dry the numerous holes W3.
In other words, when the rotation of the workpiece W and the swing operation of the nozzle holder 10 are performed and the cleaning and drying of the workpiece W are started, the nozzle 13 is generated by the target (position information of the workpiece W) recorded in the control unit 21. The injection position is determined, and the cleaning operation and the drying operation are sequentially performed, and processing of each part of the workpiece W is performed.

  At this time, if there is a change in the injection position of the nozzle 13 (due to a malfunction), the operation is stopped, the target of the control unit 21 is returned to normal, and the operation is started again, so that skill is required easily. Without having to return to normal. However, if the operator is unable to return the target position to normal, as described above, for example, a personal computer, telephone, or other communication at a remote location from the washing machine manufacturer or in an emergency in the case of overseas. By using the means, an instruction is given to the parties, and the information stored in the storage unit of the control unit 21 is corrected. The information stored in the storage unit of the control unit 21 can be used to return the injection position of the nozzle 13 to normal.

The rotation speed of the workpiece W, the swing speed of the nozzle holder 10, and the like can be controlled by the control unit 21.
Subsequently, regarding the storage of the position information of the workpiece W by the irradiation of the laser pointer A in the control unit 21, the determination of the injection position of the nozzle 13 based on this storage, the normal operation, and the maintenance at the time of failure, etc. An example will be described based on the flowchart of FIG.
In the first step ST-1, the control unit 21 rotates the motor 1200, rotates the workpiece support 12 together with the workpiece W, and swings the nozzle holder 10 (ST-1).
In the next step ST-2, the operator turns on the power supply 6 (ST-2). Thereby, irradiation of the laser beam by the laser pointer A attached to the nozzle holder 10 starts (ST-3). That is, each position of the hole W3 is irradiated with a laser beam, and the engineer of the cleaning manufacturer visually determines whether or not the position is accurate (ST-4). In doing so, reference is made to conventional techniques and / or experience.
If the result of determination is NO (failure) (ST-4: NO), the process returns to (ST-3). On the other hand, if the result of determination is OK (good) (ST-4: OK), the position obtained by irradiating the laser beam is regarded as the injection position (target) of the nozzle 13 and the copying means 20 (teaching device). Teaches by storing the position information of the workpiece W as the injection position information (target) for numerical control in the storage unit of the control unit 21 (ST-5) and (ST-6).
Next, the laser pointer A is removed from the nozzle holder 10, and the nozzle 13 is attached instead.
In the next step ST-7, the control unit 21 rotates the motor 1200, rotates the work support 12 together with the work W, and swings the nozzle holder 10 (ST-7). Since the injection position and the injection direction of the nozzle 13 are guaranteed by the information stored in the control unit 21, the predetermined position of the work W is reliably and individually injected, and predetermined cleaning, Predetermined drying can be achieved.
In the next step ST-8, the operator judges visually and / or empirically whether or not cleaning and drying have been properly performed (ST-8). In this determination, if it is OK (ST-8: OK), the processing has been completed (ST-9), and the series of operations is completed. In the case of NO (ST-8: NO), the process returns to step ST-6 (ST-8a), and teaching is performed again (ST-5) and (ST-6).

  In addition, the work etc. which are not illustrated in a flowchart follow a conventional example.
