DETAILED DESCRIPTION

[0033] The following will be combined with the drawings Figure 1 - the drawings Figure 3 The application will be further described in detail.

[0034] The embodiment of the application discloses a high-precision spray washing machine, which refers to Figure 1 , the high-precision spray washing machine comprises a machine body 1, the machine body 1 is internally provided with a conveying mechanism 6, the conveying mechanism 6 comprises a plurality of axis-parallel conveying rollers 64 rotationally connected in the machine body 1, and part of the conveying rollers 64 are rotationally driven by a motor. The conveying mechanism 6 further comprises a conveying belt 61 which is wound outside the plurality of conveying rollers 64 and is in a taut state with the head and tail being connected. The conveying belt 61 is mainly elastic and can be bent into an arc shape when passing through the position of the conveying roller 64. When the motor is driven, the conveying belt 61 can be moved in one direction. The application takes the movement of the conveying belt 61 in the clockwise direction as an example.

[0035] Referring to Figure 1The body 1 is sequentially provided with a high-pressure spraying mechanism 2, an ultrasonic cleaning mechanism 3, a low-pressure rinsing mechanism 4, and a wind cutting drying mechanism 5 along the moving direction of the upper part of the conveying belt 61. The conveying belt 61 is provided with a mounting seat 65, and the mounting seat 65 is connected with a clamping tool 7. The clamping tool 7 is used for detachably clamping a workpiece. When the conveying belt 61 moves to drive the workpiece to move, the workpiece can sequentially pass through the above mechanisms.

[0036] The high-pressure spraying mechanism 2 comprises a spraying tank 21 and a plurality of high-pressure nozzles arranged in the spraying tank 21. The high-pressure nozzles can spray high-pressure water to wash the workpiece in the spraying tank 21 to remove part of impurities. The ultrasonic cleaning mechanism 3 comprises an ultrasonic cleaning tank 31. The ultrasonic cleaning tank 31 is internally provided with a plurality of ultrasonic vibration plates capable of forming ultrasonic waves. The ultrasonic cleaning tank 31 is internally left with ultrasonic cleaning liquid. When the workpiece is located in the ultrasonic cleaning liquid, the workpiece can be further cleaned in cooperation with the ultrasonic vibration plates. The low-pressure rinsing mechanism 4 comprises a rinsing tank 41 and a plurality of nozzles arranged in the rinsing tank 41. The nozzles can spray rinsing liquid to clean the workpiece in a low-pressure form. The wind cutting drying mechanism 5 comprises a fan and a plurality of blowing ports communicated with the fan. The airflow formed by the fan can be blown out through the blowing ports to dry and blow off water from the workpiece.

[0037] In addition, the high-pressure spraying mechanism 2, the low-pressure rinsing mechanism 4, and the ultrasonic cleaning mechanism 3 are all provided with corresponding liquid storage tanks, recovery pipelines, filters, and water pumps to form a recyclable loop structure. This is a conventional means, and thus will not be described here. Since the conveying belt 61 needs to pass through the ultrasonic cleaning liquid of the ultrasonic cleaning mechanism 3 for cleaning, the part of the conveying belt 61 located in the ultrasonic cleaning tank 31 comprises a first inclined section 611 and a second inclined section 612, and a horizontal section 613 located between the first inclined section 611 and the second inclined section 612. By arranging the first inclined section 611 and the second inclined section 612, the position of the horizontal section 613 can be lower to be completely immersed in the ultrasonic cleaning liquid.

[0038] Referring to and Figure 2The clamping tool 7 is connected with the mounting base 65 to move together with the mounting base 65. The clamping tool 7 specifically includes a clamping frame 71, which is taken as a rectangular ring type in the embodiment. Two abutting strips 72 are slidably connected in the clamping frame 71, and the sliding directions of the two abutting strips 72 are the same, and the two abutting strips 72 can move towards or away from each other. The surfaces of the two abutting strips 72 away from each other are connected with springs 73 and telescopic rods with the inner wall of the clamping frame 71 to realize the movement of the two abutting strips 72. The workpiece can be placed between the two abutting strips 72, and the abutting strips 72 can clamp the workpiece through the elastic force of the springs 73 to realize the fixation of the position of the workpiece. The surfaces of the two abutting strips 72 towards each other are provided with guide inclined surfaces 75 in the direction close to the conveying belt 61, and the distance between the two guide inclined surfaces 75 is constantly shortened. Through the setting of the guide inclined surfaces 75, after the mechanical hand clamps the workpiece, the workpiece and the clamping tool 7 can be conveniently fixed or separated through the way of pressing down or pulling up, which is easy to realize the automatic feeding and discharging.

[0039] With reference to Figure 1 and Figure 2 The surfaces of the two abutting strips 72 away from each other are rotatably connected with reinforcing strips 74 through bolts as pin shafts. The reinforcing strips 74 have elasticity, and after the reinforcing strips 74 are rotated to appropriate positions, the rotation of the reinforcing strips 74 can be limited by tightening the bolts. When the workpiece needs to be further reinforced, the position of the reinforcing strips 74 can be adjusted in advance according to the specific shape of the workpiece, and then the clamping effect is adjusted.

[0040] With reference to Figure 1 and Figure 3 Since the conveying surface is no longer a plane but an arc surface when the conveying belt 61 passes through the position of the conveying roller 64 in the moving process, if the mounting base 65 and the conveying belt 61, and the mounting base 65 and the clamping tool 7 are rigidly connected, the mounting base 65 and the clamping tool 7 can be damaged.

[0041] Therefore, with reference to Figure 1 and Figure 3The mounting seat 65 body is also a flexible plate that can be bent. The mounting seat 65 upper and lower surfaces are each provided with a plurality of first sliding grooves 651. In this embodiment, four first sliding grooves 651 are arranged in a rectangular manner, and the length direction of the first sliding grooves 651 is along the moving direction of the conveying belt 61. The first sliding grooves 651 on the upper surface of the mounting seat 65 are inverted T-shaped grooves, and the first sliding grooves 651 on the lower surface of the mounting seat 65 are T-shaped grooves. The bottom of the clamping tool 7 and the surface of the conveying belt are each vertically fixed with a fixing strip 63. The fixing strip 63 is a telescopic rod, and includes an inner rod 631 and an outer tube 632 that are slidably connected in an inner-outer sleeving manner. The end of the inner rod 631 away from the outer tube 632 is fixedly connected with a spherical head 633 that slides in the first sliding groove 651. The spherical head 633 is limited by the structure of the first sliding groove 651 and is not easy to come off the first sliding groove 651. The end of the outer tube 632 away from the inner rod 631 is used to be fixed with the conveying belt 61 or the clamping tool 7. The fixing strip 63 is provided in a telescopic structure, so that the spherical head 633 is not easy to generate a large force on the inner wall of the first sliding groove 651 when the conveying belt 61 is at a large corner position, and can adapt to the deformation of the mounting seat 65.

[0042] The working principle of the high-precision spray cleaning machine is as follows. When working, the mechanical arm clamps and presses the workpiece into the clamping tool 7 to be clamped and fixed by the clamping tool 7. The conveying belt 61 is started to drive a plurality of workpieces to sequentially pass through the high-pressure spraying mechanism 2, the ultrasonic cleaning mechanism 3, the low-pressure rinsing mechanism 4 and the air cutting dryer to be cleaned and dried. Finally, the mechanical arm clamps the workpiece to take away the workpiece.

[0043] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
