Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing basket for cleaning, immersion plating and the like and a processing apparatus using the same.

[0002]

2. Description of the Related Art Metal parts and the like are subjected to various treatments such as washing and plating and then provided for assembly, and among these treatments, washing treatment and plating treatment are important. Both the cleaning treatment and the plating treatment are performed by immersing the object to be treated in an appropriate treatment liquid, and various devices and methods have been conventionally used as means for efficiently performing these treatments. The following is a list of cleaning processes as the main prior art.

(1) It is practiced to put an object to be cleaned in a treatment car and perform cleaning by vibrating ultrasonic waves while raising and lowering the car in a cleaning treatment liquid. Here, a method is proposed in which the fundamental frequency of ultrasonic waves is frequency-modulated to eliminate uneven cleaning (for example, Japanese Patent Laid-Open No. 61-10).
1283).

(2) Similarly, while raising and lowering the mesh basket,
It has been proposed to carry out a cleaning process without uneven cleaning by alternately irradiating the object to be cleaned with ultrasonic waves having different frequencies (for example, Japanese Patent Laid-Open No. 58-166973).

(3) Further, the weight of the apparatus main body in which the object to be cleaned stored in the processing basket is moved up and down in the processing tank by the elevating mechanism to be cleaned by the relatively generated water flow The device for simplification is elaborate (for example, Japanese Utility Model Publication No. 3-17987).

[0006]

As described above, the conventional cleaning processing apparatus is one in which an object to be cleaned is placed in a processing basket and is moved up and down in a cleaning tank to perform cleaning. Has the following problems.

First, since the bottom surface and all side surfaces of the processing basket are meshed, the liquid flow when the processing basket is moved up and down varies depending on the arrangement of the object to be cleaned, and uneven cleaning occurs depending on the location. . Secondly, the objects to be cleaned housed in the processing basket are likely to gather on the outer peripheral portion of the bottom surface as the processing basket moves up and down, resulting in uneven cleaning and poor cleaning.
Thirdly, when a relative water flow is obtained by elevating and lowering the treatment basket, a water flow at a sufficient speed cannot be obtained, so that the objects to be cleaned are not sufficiently stirred, and the objects to be cleaned overlap each other. Is not eliminated and uneven cleaning occurs. These problems apply to the plating process as well.

SUMMARY OF THE INVENTION An object of the present invention is to provide a processing car which does not cause uneven processing or defective processing of an object to be cleaned, and a processing apparatus using this car.

[0009]

In order to achieve the above object, the treatment basket of the present invention is a treatment basket for accommodating the treatment target when performing a treatment such as plating or cleaning. A first liquid flow control which is composed of a mesh cage portion to be housed and a tubular portion made of a thin plate material which is connected to the upper end portion thereof, is provided at the bottom portion of the mesh cage portion, and spreads obliquely downward in a tapered shape. Plate, second liquid flow control plate provided at the bottom of the mesh cage and extending obliquely upward, third liquid flow control plate provided at the upper end of the cylinder and extending obliquely upward
At least one of the liquid flow control plates.

The upper end of the tubular portion of the processing basket is covered with a top plate, and the top plate may be provided with a funnel-shaped hollow tubular body whose bottom is narrowed.

The treatment apparatus of the present invention uses the above-mentioned treatment basket, and includes a treatment tank in which the treatment liquid in which the treatment basket is immersed is contained, a cage for holding the above-mentioned treatment basket, and this cage. And an elevating drive means for elevating the receiver.

[0012] This processing apparatus is preferably constituted by a meshed car portion for accommodating an object to be treated, and a tubular portion made of a thin plate material which is connected to an upper end portion of the treated cage. The basket receiver is provided with a descending liquid flow control plate that tapers diagonally downward around the bottom that holds the processing basket, and tapers diagonally upward around the bottom that holds the processing basket. A rising liquid flow control plate is provided. At least one of these liquid flow control plates is fixed.

More preferably, a rising liquid flow control plate is provided at the upper end of the tubular portion of the processing basket, the rising liquid flow control plate extending obliquely upward. Furthermore, even in this processing device,
The upper end of the tubular portion of the processing basket is covered with a top plate, and a funnel-shaped hollow tubular body with a narrowed bottom may be formed on the top plate.

[0014]

The present invention produces the following actions by adopting the above means. The tubular portion that constitutes the processing car controls the liquid flow generated by the lifting and lowering operation of the processing car, and the first liquid flow control plate controls the liquid flow that flows into the mesh car part when the processing car descends in the processing liquid. The liquid flow is controlled so as to accelerate and concentrate in the central portion. The second liquid flow control plate speeds up the liquid flow flowing into the mesh car when the processing car moves up in the processing liquid, and controls the liquid flow so as to concentrate in the central part. Similarly, when the processing car moves up in the processing liquid, the third liquid flow control plate collects the processing liquids located above the processing car and guides them into the cylindrical portion to increase the liquid flow flowing into the mesh car portion. By speeding up
The contained object is agitated.

By covering the upper end of the tubular portion with a top plate and providing a funnel-shaped hollow tubular member on the top plate, the treatment liquid located above the treatment basket is moved to the third position when the treatment basket is raised. The treatment liquid is collected on the top plate by the liquid flow control plate, and the collected treatment liquid becomes a high-speed jet flow by the hollow cylindrical body and flows down into the treatment basket to stir the object to be treated contained in the mesh cage. .

A processing apparatus using these processing baskets is
The processing car is held by a car receiver, and the car receiver is moved up and down by an elevating drive means, and the liquid flow is controlled by the liquid flow control plate of the processing car and the hollow cylindrical body.

The processing car is composed of a mesh car part and a cylinder part connected to the mesh car part, and at least one of a descending liquid flow control plate and an ascending liquid flow control plate is provided on the bottom part of the car receiver. However, the same operation as in the case where at least one of the first and second liquid flow control plates is provided in the processing car occurs.

If an ascending liquid flow control plate is further provided at the upper end of the tubular portion of this processing car, the descent and ascending liquid flow control plates provided at the car receiver are accommodated in the mesh car part. The ability to stir the processed product is improved.

If necessary, a top plate is provided at the upper end of the tubular part, and if a funnel-shaped hollow tubular body is provided on this top plate, it will flow into the mesh cage from above as a jet flow. Stir the object to be treated more effectively.

The above-mentioned first to third liquid flow control plates provided in the processing car may be arbitrarily provided in accordance with the processing conditions, and not all the liquid flow control plates have to be provided. .

Next, an ultrasonic cleaning apparatus as a processing apparatus using the processing basket 1 described above will be described with reference to FIG. The body 31 of the ultrasonic cleaning device is fixed on a base 33 supported by support legs 32. The outer frame 34 erected on the base 33 has a treatment tank portion 34 at the right two-thirds portion.
a, and the left one-third portion is used as the drive unit 34b.

The processing tank 35a made of a stainless steel container is provided in the processing tank portion 34a. A processing liquid (detergent aqueous solution) L is contained in the processing tank 35. An ultrasonic generator 37 is attached to the lower surface of the bottom of the processing tank 35 via a flange 36.

The drive unit 34b is provided with an elevating and lowering drive means 39 composed of a linear actuator on a mount 38.
The output rod 39a of the elevating / lowering drive means 39 is slidably supported by the sleeve 40 fixed to the outer frame 34, and the upper end portion thereof projects to the upper surface of the outer frame. In the protruding portion, the horizontal portion 41a of the L-shaped lifting arm 41 is formed.
One end of is stuck. Horizontal part 41 of the lifting arm 41
A vertical portion 41b hangs down from the other end of a, and the lower half of the vertical portion 41b is immersed in the treatment liquid L in the treatment tank 35.

At the lower end of the vertical portion 41b of the lifting arm,
A holder 42 formed in a ring shape having a predetermined width is attached. The outer peripheral portion of the holder 42 is fixed to the lower end portion of the vertical portion 41b of the elevating arm.

The inner peripheral portion of the holder 42 is in contact with and supports the outer peripheral portion of the car receiver 43. Basket 43
In the above, the inner portion is removed leaving only the bottom portion necessary for holding the treatment basket 1 so that the treatment liquid can freely move. The rising portion 43a has an upper portion widened from a position of approximately two-thirds of the height to facilitate the loading and unloading of the processing basket. On the base 33, adjacent to the outer frame 34, there is provided a preliminary tank 44 in which the replenishing processing liquid L0 is contained.

Next, the operation of this embodiment will be described.

First, the object to be cleaned is put in the processing basket 1, the top plate 7 is covered on the upper end of the cylindrical portion 3, and it is fixed so as not to come off during the cleaning operation (see FIGS. 1 and 2). Next, the processing car 1 is accommodated in the car receiver 43 installed in the processing tank 35 via the suspending tool 8. Here, when the ultrasonic wave generator 37 is started, the processing liquid L vibrates and the object to be cleaned is cleaned. As for the ultrasonic vibration, since the bottom of the car receiver 43 is open, the vibration acts directly on the object M to be processed from below the processing car 1 to perform the cleaning operation. With the generation of ultrasonic waves, the elevating and lowering driving means 39 is started, and the elevating arm 41 causes the process car 1 to move up and down in the processing liquid L _O via the holder 42 and the car receiver 43. Processing basket 1
The up-and-down movement of the above-mentioned works by the three liquid flow control plates 4 to 6 as follows.

First, when the processing car 1 is lowered, as shown in FIG. 4, the liquid flow flowing into the processing car from below the processing car is accelerated by the first liquid flow control plate 4, and further, from the surroundings toward the center. Since the object M to be cleaned flows into the mesh basket portion 2, the objects M to be cleaned move so as to gather in the central portion without staying in the peripheral portion of the bottom surface.

When the processing basket 1 is lowered by a predetermined amount in this way, it is reversed and the upward movement is started. At this time, in addition to the relative liquid flow generated by the rise of the processing car 1, the liquid around the processing car 1 flows toward the mesh car part 2 by the second liquid flow control plate 5 as shown in FIG. The liquid flow acting on the object to be cleaned M is accelerated, and the object to be cleaned M is agitated to exert a high cleaning power. At this time as well, the liquid flow by the second liquid flow control plate 5 is directed toward the center, so that the objects to be cleaned M are gathered in the center while being stirred.

During the upward movement of the processing car 1, the liquid above the processing car 1 is further collected by the third liquid flow control plate 6 and sent to the mesh car part 2. Therefore, the speed of the liquid flow is high. The cleaning ability is higher.

In the case where the top plate 7 is further provided, the liquid collected by the liquid flow control plate 6 is collected into the hollow cylindrical body 7.
Since a jet flow is generated by a and a concentrated liquid flow is generated at several places, a high-speed liquid flow is exerted on the object M to be processed overlapping in the mesh basket portion 2 to stir more effectively and to perform uniform cleaning. It is possible.

After the elevating and lowering motions have been performed a predetermined number of times, the processing car 1 is pulled up by the robot device (not shown) via the suspending tool 8 and the next processing car is fed to perform the same processing.

In this embodiment, a linear actuator is used as the lifting drive means, but the lifting drive means may be a hydraulic cylinder or a cam type.

Next, another embodiment will be described. In this embodiment, since the basic structure of the processing apparatus is the same as that of the above-mentioned embodiments, the description of the common components will be omitted, and only the different parts will be described.

As shown in FIG. 6, the processing car 51 is composed of a meshed car part 52 for accommodating the object M to be processed and a tubular part 53 made of a thin plate material and connected to the upper end part thereof. . A rising liquid flow control plate 56, which is widened obliquely upward in a tapered shape, is fixed to the upper end of the cylindrical portion 53. In addition, the tubular portion 5
A top plate 57 is attached to the upper end of 3, that is, the lower end of the rising liquid flow control plate 56 so as to cover the opening of the processing basket 51. The top plate 57 is provided with a plurality of funnel-shaped hollow cylindrical bodies 57a. The ascending liquid flow control plate 56 and the top plate 57 are the same as the third liquid flow control plate 7 and the top plate 7 in the above-described embodiment, and the presence or absence of these devices may be similarly appropriately selected. Good.

Around the bottom of the car receiver 73, a descending liquid flow control plate 74 that widens in a slanting downward direction and a rising liquid flow control plate 75 that widens in a slanting upward taper are fixed. I am doing it. These two liquid flow control plates 74, 7
Reference numeral 5 corresponds to the first and second liquid flow control plates in the above-mentioned embodiment, and has the same function as these.
The processing basket 51 and the like are moved up and down through the arm 71.
By 9 it is possible to move up and down in the processing liquid. Other than that, the configuration of the apparatus main body including the elevating and lowering drive means 69 is the same as that of the above-described embodiment, and therefore the description thereof is omitted.

Next, the operation of this embodiment will be described. The processing basket 51 accommodating the object to be processed is mounted on the car receiver 73, and the car receiver 73 and the processing car 51 are moved up and down via the arm 71 while applying ultrasonic waves. When both are descending, the processing liquid L located below the car receiver 73 is accelerated by the descending liquid flow control plate 74 and flows into the mesh cage 52 of the processing car from the bottom of the car receiver. As a result, the object to be processed in the mesh basket portion 52 is agitated while receiving the force toward the center portion, and the cleaning action is performed. Next, when both of them move upward, the processing liquid L located around the car receiver 73 flows from the surroundings toward the center of the mesh cage 52 of the processing car by the ascending liquid flow control plate 75 and The treated product is washed with stirring. At the same time, the processing liquid L located above the processing basket 51 is scraped up by the rising liquid flow control plate 56 provided at the upper end of the processing basket, and is accelerated and flows into the tubular portion 53 to flow into the mesh basket. The object to be treated contained in the section 52 is stirred and washed.

When the top plate 57 is attached to the upper end of the cylindrical portion 53, the treatment liquid L collected on the top plate by the rising liquid flow control plate is jetted by the hollow cylindrical body 57a. Then, it flows into the processing basket and exerts a more effective stirring action on the object to be cleaned.

In this embodiment, since the liquid flow control plate is not provided at the bottom of the processing car 51, the size of the processing car accommodated in the car receiver 73 can be increased by that amount, as compared with the above embodiments. Besides, there is an advantage that the processing basket can be easily put in and taken out. Further, the liquid flow control plates 74 and 75 provided on the car receiver 73 act in common on any processing car even if the processing cars having a simple shape without the liquid flow control plate are sequentially replaced. Therefore, it is not necessary to provide a liquid flow control plate in the processing basket. Alternatively, since the number of liquid flow control plates of the processing car can be reduced, there is an advantage that the cost of the processing car can be reduced.

In the present embodiment, the descending liquid flow control plate, the ascending liquid flow control plate, and the ascending liquid flow control plate, the top plate and the like may be selectively provided.

In each of the embodiments, the object to be processed is the object to be cleaned and the processing apparatus is the cleaning apparatus, but the present invention is not limited to this, and other processing such as immersion plating is possible. Is also applicable. Of course, when a plating apparatus is used, it is necessary to have a structure corresponding to it, but in this case as well, it is possible to prevent uneven plating and defective plating.

[0049]

As described above, according to the present invention, the treatment basket is fixed to the mesh basket portion made of the mesh body and the cylindrical portion made of the thin plate material, and at least one of the three liquid flow control plates is attached to the cage.
Since the object is placed in this treatment basket and moved up and down in the treatment liquid, the accelerated liquid flow flows toward the treatment object, so that the treatment object is agitated efficiently. It is possible to carry out uniform cleaning and other processing.

Further, by providing a top plate having a plurality of hollow cylindrical members on the upper end of the tubular portion of the processing car, the processing liquid above the processing car is placed on the top plate when the processing car rises. The treatment liquid is accelerated from the hollow cylindrical body provided in the above and is poured as a jet onto the object to be treated in the treatment basket, so that the object to be treated is more effectively agitated to further reduce the unevenness of treatment. It can be reduced.

In addition, when these processing baskets are received as baskets,
By using this processing apparatus equipped with the car receiver lifting / lowering drive means, it is possible to obtain a processing apparatus having a high processing efficiency by the action of the liquid flow control plate and the top plate.

If a liquid flow control plate is provided on the car receiver itself, the liquid flow control plate of the processing car is not required and the structure of the processing car can be simplified, so that the cost of the processing car can be reduced and the inside of the car receiver can be reduced. It is easy to store the object in the container and the area of the object to be processed can be increased.
