Description

Technical Field

[0001] The invention relates to the technical field of surface infiltration, and in particular to a device for uniformly solidifying infiltration liquid on the surface of a workpiece. Background Art

[0002] Infiltration is a surface treatment process that involves partially or completely immersing the workpiece in a surface molding liquid so that the molding liquid covers the surface of a specified area of ​​the workpiece, and then solidifies the surface of the area into a solidified layer. Depending on the type of workpiece, the solidified layer can be used to protect the workpiece, objects in contact with the workpiece, or other objects. For example, after the surface of a rubber glove workpiece is infiltrated with molding liquid to form a solidified layer, the solidified layer can provide better protection for the rubber gloves, preventing sharp objects such as metal debris from being damaged by the rubber gloves. At the same time, it can also further improve the protective effect of the rubber gloves on the hands, preventing sharp objects from damaging the rubber gloves and scratching the hands.

[0003] During the solidification process of the liquid on the workpiece surface, the high speed and uniformity of the liquid solidification have a direct impact on the quality of the workpiece and are important determinants of the workpiece quality. In the prior art, after the workpiece is infiltrated, it needs to be positioned above the molding liquid for a certain period of time to allow the excess molding liquid on the workpiece surface to drip off. Although this treatment method utilizes the natural effect of gravity to remove most of the excess molding liquid on the workpiece surface, it is also difficult for the molding liquid to solidify evenly on the glove surface due to the effect of gravity, which directly affects the quality of the infiltration process and the overall quality of the product.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figure 1~Figure 3 As shown, its structural relationship is as follows: the stand 12 is upright and fixed on the top of the base 1, the rotating spindle 22 is installed on the stand 12 in a transverse rotation, and either end thereof is installed and connected to the output end of the fixedly installed driving machine 21; the rotating disk 23 is installed and fixed on the rotating spindle 22, and each workpiece support frame 4 is circumferentially installed and fixed on it, and each workpiece 6 is respectively installed on the mounting rod of each workpiece support frame 4, and is clamped and limited by each material card 5.

[0034] Preferably, it also includes a linear actuator 3 mounted and fixed on the stand 12;

[0035] The material card 5 includes a rotating block 52 and a fixed block 53 which are rotatably installed to form a rotating pair. A spring 56 is installed between the inner ends of the fixed block 53 and the rotating block 52. The outer end of the rotating block 52 is located outside the fixed block 53 and is fixed with a thrust rod 51. The rotating block 52 can be rotated under the action of the spring 56 until the inner end is pressed against the top of the workpiece 6 installed on the workpiece support frame 4, and can be rotated under the action of the linear actuator 3 until the inner end is away from the mounting rod of the workpiece support frame 4.

[0036] Preferably, a limiting top column 54 is provided at the front end of the fixed block 53 for limiting the rotation limit position of the rotating block 52 to prevent the rotating block 52 from exerting excessive pressure on the workpiece 6 and damaging the workpiece 6. A soft film 57 is provided at the contact position between the inner end of the rotating block 52 and the workpiece 6 to prevent the rotating block 52 from scratching the workpiece 6 when pressing the limited workpiece 6.

[0037] Preferably, a notch is formed at the inner end of the fixed block 53, the rotating block 52 is embedded in the notch, and is rotatably mounted with the fixed block 53 via a pair of small rotating shafts 55 symmetrically arranged on both sides thereof to form a rotating pair.

[0039] Preferably, the number of linear actuators 3 is set to two and a material card 5 is installed on both sides of each workpiece support frame 4; the two linear actuators 3 are respectively installed and fixed to the top of a pair of brackets, and the linear motion output by the two linear actuators 3 acts on the thrust rods 51 of the two material cards 5 respectively.

[0040] Preferably, the top of the base 1 is fixedly provided with lifting rings 11; the lifting rings 11 can be connected to the lifting equipment of the production site, so that the rotary homogenizing device can be better connected with existing automation equipment such as industrial robots.

The input end of the reducer is axially coupled to the output end of the driving machine 21 , and the output end is axially coupled to the rotating main shaft 22 .

[0042] Preferably, a liquid leak-proof plate 41 is also provided at the bottom of the workpiece support frame 4; because each workpiece support frame 4 is installed and fixed to the rotating disk 23 in a circumferentially uniform manner, when the workpiece support frame 4 rotates with the rotating disk 23, it will periodically rotate to above the rotating spindle 22, and other workpiece support frames 4 will periodically rotate and pass below the workpiece support frame 4; the liquid leak-proof plate 41 is used to prevent the wetting liquid on the upper workpiece 6 from dripping onto the rotating spindle 22 and damaging the rotating liquid homogenizing device, and at the same time prevent the wetting liquid on the upper workpiece 6 from dripping onto the lower workpiece 6, thereby adversely affecting the quality of the lower workpiece 6.

[0043] The use of the rotating liquid homogenizing device to homogenize the workpiece surface includes the following steps:

[0044] In the first step, the driving machine 21 drives the rotating spindle 22 and the rotating disk 23 fixed thereon to rotate until a designated workpiece support frame 4 moves to the top of the rotating disk 23, at which time the workpiece support frame 4 is in a front-facing posture;

[0045] In the second step, the linear actuator 3 extends and acts on the end of the rotating block 52 of the material card 5, so that the rotating block 52 rotates to the inner end away from the mounting rod of the workpiece support frame 4;

[0046] In the third step, a worker or an automatic loading robot installs the workpiece 6 transported by the handling mechanism onto the mounting rod of the workpiece support frame 4, the linear actuator 3 retracts, and the rotating block 52 rotates to the inner end under the action of the spring 56 and presses the workpiece 6 against the top of the workpiece 6, thereby pressing the workpiece 6 to be limited on the mounting rod.

[0047] When the rotating liquid homogenizing device is used to disassemble the workpiece 6, the following process is included:

[0048] In the first step, the driving machine 21 drives the rotating spindle 22 and the rotating disk 23 fixed thereon to rotate until a designated workpiece support frame 4 moves to the top of the rotating disk 23, at which time the workpiece support frame 4 is in a front-facing posture;

[0049] In the second step, the linear actuator 3 extends and acts on the end of the rotating block 52 of the material card 5, so that the rotating block 52 rotates to the inner end away from the mounting rod of the workpiece support frame 4;

[0050] In the third step, a worker or an automatic unloading robot removes the workpiece 6 from the mounting rod and places it on a transport mechanism for transportation, and then the linear actuator 3 retracts and returns to its original position.

[0051] When the above-mentioned rotating liquid homogenizing device rotates the liquid, the driving machine 21 drives the rotating main shaft 22 and the rotating disk 23 fixed thereon to rotate slowly and uniformly, so that the liquid just soaked on the workpiece 6 is evenly covered on the surface of the workpiece 6. At the same time, through the rotation of each structure, an airflow is formed in the space around the workpiece 6, thereby accelerating the solidification of the soaked liquid on the surface of the workpiece 6.
