Figure 2

[0035] The connecting seat 2 is provided with a guide assembly 6, and the guide assembly 6 is used for cooperating with the first cylinder 31; specifically, a spiral guide groove 311 is arranged on the outer wall of the first cylinder 31; the guide assembly 6 comprises a support rod 61 fixedly arranged on the connecting seat 2, and a guide ball 62 is fixedly connected to the end of the support rod 61 away from the connecting seat 2, and the guide ball 62 is cooperatively arranged in the spiral guide groove 311; that is, the guide ball 62 cooperates with the spiral guide groove 311, and since the first cylinder 31 is rotatably arranged on the support shaft 36, when the first cylinder 31 moves downward, the first cylinder 31 can rotate, and the first cylinder 31 rotates around its own axis.

[0036] The transmission member 35 comprises two transmission gears 351, the two transmission gears 351 are fixedly sleeved on the outer portions of the first cylinder 31 and the second cylinder 32 respectively, and the two transmission gears 351 are engaged with each other; when the first cylinder 31 rotates, the second cylinder 32 can rotate through the engagement between the two transmission gears 351, and the first cylinder 31 and the second cylinder 32 rotate in opposite directions.

[0037] ​When the electromagnetic chuck 71 is powered off, the support base 4 is lowered and contacts the elastic blocking strip 21, the rotation angle of the first cylinder 31 and the second cylinder 32 is not more than 180 degrees, which can be achieved by setting the elastic blocking strip 21 at a suitable height, or other ways which are not described here; of course, when the support base 4 contacts the elastic blocking strip 21, the guide ball 62 is still matched with the spiral guide groove 311; the elastic blocking strip 21 is made of elastic material with strong impact resistance, such as polyurethane or silicone rubber, etc.

[0038] The transmission ratio between the two transmission gears 351 can be set to 1, at this time the rotation speed of the first cylinder 31 and the second cylinder 32 is the same, during the lowering process of the first cylinder 31, the two connecting pieces 33 gradually move close to each other, during the process of the two connecting pieces 33 gradually moving close to each other, the included angle between the two hanging ropes 34 gradually decreases, the hanging rope 34 gradually tends to be vertical, and the distance between the material box assembly 5 and the bottom of the first cylinder 31 gradually increases; at the same time, since the connecting piece 33 rotates in the horizontal direction, it not only changes the height of the material box assembly 5, but also changes the position of the material box assembly 5 in the horizontal direction.

[0039] The transmission ratio between the two transmission gears 351 can also be set to be close to 1, at this time the rotation direction of the first cylinder 31 and the second cylinder 32 is opposite, and the rotation speed is different, during the lowering process of the support base 4, compared with the transmission ratio between the two transmission gears 351 being 1, it is easier to cause the material box assembly 5 to deflect; of course, the rotation angle of the first cylinder 31 and the second cylinder 32 is not more than 180 degrees.

[0040] The material box assembly 5 includes a material box frame 51, the material box frame 51 is matched with the workpiece, specifically, the material box frame 51 is provided with a groove structure matched with the workpiece, a part of the workpiece is placed in the groove, and the contact area between the workpiece and the material box frame 51 is small; a plurality of support protrusions 511 are further provided on the material box frame 51, the support protrusions 511 are used to support the workpiece; two cross bars 52 are rotatably provided on the material box frame 51, the two cross bars 52 are symmetrically arranged and coaxial, each cross bar 52 is movably arranged on the material box frame 51 through a bearing, and the bottom end of the hanging rope 34 is fixedly arranged on the cross bar 52.

[0041] In order to fix the workpiece, two pressing strips 53 are further provided, one end of the pressing strip 53 is hinged to the material box frame 51, the other end of the pressing strip 53 is connected to the material box frame 51 by a buckle, that is, the other end of the pressing strip 53 is detachably arranged on the material box frame 51; a contact protrusion 531 is arranged on the inner side of the pressing strip 53, the contact protrusion 531 is used to contact the workpiece, through the cooperation of the pressing strip 53 and the material box frame 51, and through the contact of the contact protrusion 531 with the workpiece, the fixing effect of the workpiece is achieved; the support protrusion 511 and the contact protrusion 531 can be arranged in a bullet head or a hemispherical structure, etc., to reduce the contact area with the workpiece.

[0042] In the embodiment, the hanging conveying line is used in cooperation with an ultrasonic cleaning pool or an ultrasonic cleaning tank, that is, the workpiece is placed on the magazine frame 51, and the workpiece is fixed by cooperating the pressing strip 53 with the magazine frame 51; the workpiece is moved to above the ultrasonic cleaning pool or the ultrasonic cleaning tank by the annular conveying line 1, and of course, the annular conveying line 1 is arranged at a proper height, or the ultrasonic cleaning pool or the ultrasonic cleaning tank is arranged at a proper height, so as to ensure that the magazine assembly 5 is at a proper distance from the ultrasonic cleaning pool or the ultrasonic cleaning tank.

[0043] When the electromagnetic chuck 71 is powered off, the support base 4, the hanging assembly 3 and the workpiece move downward, and the support base 4 is blocked by the elastic blocking strip 21; during the downward movement of the support base 4, the first cylinder 31 rotates by cooperating the guide ball 62 with the spiral guide groove 311; since two transmission gears 351 are arranged to mesh with each other, the rotation of the second cylinder 32 can be realized; therefore, during the downward movement of the support base 4, after the support base 4 moves downward by a certain distance, the magazine frame 51 and the workpiece can enter the water body in the ultrasonic cleaning pool or the ultrasonic cleaning tank; during the downward movement of the support base 4, since the first cylinder 31 and the second cylinder 32 rotate, the first cylinder 31 and the second cylinder 32 rotate in opposite directions, thereby driving the two connecting pieces 33 to gradually move close to each other, the included angle between the two hanging ropes 34 gradually decreases, and the distance between the magazine frame 51 and the bottom of the first cylinder 31 gradually increases, that is, the downward movement distance of the workpiece is greater than the downward movement distance of the support base 4; by cooperating the adsorption assembly 7 with the hanging assembly 3, the support base 4 does not need to move downward by a large distance under the condition of meeting the requirement of the downward movement distance of the workpiece; since the electromagnetic chuck 71 needs to re-adsorb the iron ring 72 after the support base 4 moves downward to promote the reset of the support base 4, the parameter requirement of the electromagnetic chuck 71 is reduced, thereby helping to reduce the cost.

[0044] Since the first cylinder 31 and the second cylinder 32 rotate during the rotation of the connecting piece 33 in the horizontal direction, the position of the connecting piece 33 in the horizontal direction is changed, thereby changing the height of the magazine frame 51 and the workpiece and changing the position of the magazine frame 51 and the workpiece in the horizontal direction; the magazine frame 51 is hung by the hanging rope 34, and when the magazine frame 51 and the workpiece are located in the water body, the rotation of the connecting piece 33 during the rotation of the first cylinder 31 and the second cylinder 32 also easily causes the magazine frame 51 to deflect, so that the disturbance effect on the workpiece can be effectively enhanced, thereby improving the cleaning effect on the workpiece.

[0045] When the support base 4 contacts the elastic blocking after moving downward, rebounding of the support base 4 may occur, and the rebounding of the support base 4 also causes the movement of the workpiece, thereby being beneficial to cleaning.

[0046] After the workpiece is cleaned for a proper time, the electromagnetic chuck 71 is powered on, the electromagnetic chuck 71 is attracted to the iron ring 72, and the support seat 4 can be driven upward to reset, and in the process of upward movement of the support seat 4, the two connecting pieces 33 are also rotated, that is, the height of the workpiece is changed, the position in the horizontal direction is changed, and the workpiece is also easily deflected, thereby helping to shake off a part of the water remaining on the workpiece and the box frame 51, and the drying time of the subsequent drying process can be reduced; in addition, the workpiece after cleaning can be moved to the next process position through the annular conveying line 1, and the next workpiece can also be moved; when the workpiece needs to be taken out, the workpiece can be taken out by removing the detachable end of the pressing strip 53.

[0047] Embodiment two Please refer to Figure 1 and Figure 2 , the embodiment is based on the first embodiment, and a spring 8 is further arranged between the support seat 4 and the connecting seat 2, the spring 8 is sleeved outside the electromagnetic chuck 71, and the spring 8 is far away from the electromagnetic chuck 71 as far as possible; when the electromagnetic chuck 71 is attracted to the iron ring 72, the spring 8 is basically in a normal state, when the elastic blocking strip 21 blocks the support seat 4, the spring 8 is stretched, and of course the tension of the spring 8 does not affect the downward movement of the support seat 4 to contact the elastic blocking strip 21; by arranging the spring 8, the collision impact between the support seat 4 and the elastic blocking strip 21 is reduced during the downward movement of the support seat 4.

[0048] Embodiment three Please refer to Figure 2 and Figure 5 , the embodiment is based on the second embodiment, the connecting piece 33 comprises a connecting rod 331, the connecting rod 331 is vertically arranged, and the top end of the connecting rod 331 is fixed to the bottom side of the first cylinder 31 or the second cylinder 32; the fixed rod 332 is fixedly connected to the connecting rod 331, and the top end of the hanging rope 34 is fixed to the fixed rod 332.
