Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0020] Reference Figure 1 , shows a structural schematic diagram of a hook-free mechanical arm device for a washing basket, which may specifically include: a mounting plate 1, a moving plate 2, a lifting mechanism, a translation mechanism and a clamping mechanism, wherein the mounting plate 1 is located above the moving plate 2, the lifting mechanism is arranged on the mounting plate 1, and the lifting mechanism includes a lifting cylinder 31, and the telescopic end of the lifting cylinder 31 passes through the mounting plate 1 and is connected to the moving plate 2;

[0021] The clamping mechanism includes two clamping cylinders 41 and two clamping frames 42. The two clamping cylinders 41 are arranged on both sides of the movable plate 2, and the tops of the two clamping frames 42 are respectively connected to the telescopic ends of the two clamping cylinders 41.

[0023] In the embodiment of the present application, the cleaning basket is clamped by a clamping mechanism, specifically by two clamping cylinders 41 driving two clamping frames 42 to extend and retract respectively, thereby clamping or releasing the cleaning basket to achieve clamping positioning; the cleaning basket is lifted and lowered by a lifting mechanism, specifically by the extension and retraction of the lifting cylinder 31 driving the lower movable plate 2 and the clamping frame 42 to move up and down synchronously, moving into the cleaning tank for cleaning when moving down, and leaving the cleaning tank when moving up; the cleaning basket is moved horizontally by a translation mechanism, specifically by a servo motor 51 driving the gear 52 to rotate, and the gear 52 moves on the rack, driving the overall horizontal movement to each cleaning station. The present application changes the traditional hook-type cleaning method, integrating lifting, clamping, and translation, reducing repeated positioning of each process position, unifying the fluidity of the entire production line, improving cleaning efficiency, and saving production costs.

[0024] Next, a hook-free robot arm device for a washing basket in this exemplary embodiment will be further described.

[0025] In one embodiment of the present application, the mounting plate 1 is located above the movable plate 2, the lifting mechanism is arranged on the mounting plate 1, and the lifting mechanism includes a lifting cylinder 31. The telescopic end of the lifting cylinder 31 passes through the mounting plate 1 and is connected to the movable plate 2. The movable plate 2 is driven up and down by the telescopic movement of the lifting cylinder 31, thereby driving the clamping mechanism and the translation mechanism arranged on the movable plate 2 to move synchronously, thereby realizing the up and down movement of the cleaning basket.

[0026] As an example, the lifting mechanism further includes a guide rod 32 and a linear bearing 33, and four guide rods 32 and four linear bearings 33 are provided. The four guide rods 32 are respectively inserted into the four linear bearings 33, one end of the linear bearing 33 is connected to the mounting plate 1, and one end of the guide rod 32 is connected to the moving plate 2. By arranging the guide rods 32 and the linear bearings 33 around, support and guidance are provided for the movement of the moving plate 2, so that the lifting is stable.

[0027] In one embodiment of the present application, the clamping mechanism includes two clamping cylinders 41 and two clamping frames 42. The two clamping cylinders 41 are relatively arranged on both sides of the movable plate 2, and the tops of the two clamping frames 42 are respectively connected to the telescopic ends of the two clamping cylinders 41. By telescoping the clamping cylinders 41 on both sides, the clamping frames 42 on both sides are pushed to move so that the two clamping frames 42 can be relatively close to or away from each other, thereby clamping and releasing the cleaning basket.

[0028] As an example, the clamping frame 42 includes a top plate 421, a bottom plate 422 and a boom column 423, wherein the boom column 423 is disposed between the top plate 421 and the bottom plate 422, wherein the middle portion of the top plate 421 is connected to the telescopic end of the clamping cylinder 41, and the two ends of the top plate 421 are connected to the movable plate 2 via a guide assembly 424; by providing the guide assembly 424, the horizontal reciprocating movement of the clamping frames 42 on both sides is guided, specifically, the guide assembly 424 includes a guide shaft and a bearing seat, wherein the bearing seat is fixed to the movable plate 2, and the guide shaft is slidably disposed in the bearing seat and connected to the top plate 421. The bottom plate 422 is in a "︺" shape, and the protruding portions at both ends of the bottom plate 422 are used to carry the cleaning basket, i.e., the protruding portions at the inner edges at both ends of the bottom plate 422 extend inwardly to limit the cleaning basket, so that the cleaning basket is clamped more stably and will not slide downward.

[0029] As an example, the protruding portions at both ends of the bottom plate 422 are further provided with bottom positioning blocks 425, and the top positioning blocks are used to position the bottom of the cleaning basket.

[0030] As an example, the two boom columns 423 are respectively provided with a front positioning block 426 and a rear positioning block 427, and the front positioning block 426 and the rear positioning block 427 are close to the bottom plate 422. That is, the front positioning block 426 and the rear positioning block 427 are higher than the bottom positioning block 425 by a certain distance, but below the center point of the clamping frame 42, so as to facilitate the front and rear positioning of the side of the washing basket.

[0031] As an example, the front positioning block 426 and the rear positioning block 427 are both L-shaped. The front positioning block 426 and the rear positioning block 427 are set to be L-shaped, so that they form a relatively hooked structure on the clamping frame 42. When the cleaning basket is clamped, the front positioning block 426 and the rear positioning block 427 clamp the front and rear opposite surfaces of the cleaning basket, and the arm column 423 of the clamping frame 42 and the bottom positioning block 425 clamp the left and right opposite surfaces of the cleaning basket, thereby making the clamping of the cleaning basket more stable, and no shaking or swinging occurs during the cleaning process, so that it falls into each process position more accurately and is accurately positioned.

[0032] In one embodiment of the present application, the translation mechanism includes a servo motor 51, a gear 52 and a rack (not shown in the figure), the servo motor 51 is arranged on the mounting plate 1, the gear 52 is sleeved on the output shaft of the servo motor 51, the rack is meshed with the gear 52, and the rack is fixedly connected to an external support. The servo motor 51 drives the gear 52 to rotate, the rack is meshed with the gear 52, and the rack is fixed to the external support, so that the gear 52 moves on the rack, thereby driving the device as a whole to move horizontally along the length direction of the rack, and the device can be moved to each cleaning process position, which is convenient for the selection of different cleaning processes and improves the adaptability of the production line.

[0033] As an example, a press frame sensing alarm mechanism 6 is further included, and the press frame sensing alarm mechanism 6 is arranged on the top of the clamping frame 42 and connected to the movable plate 2; the press frame sensing alarm mechanism 6 is used to detect that the press frame is close to the clamping frame 42. By setting the press frame sensing alarm mechanism 6, an alarm is generated when the press frame is close to the clamping frame 42, thereby preventing the press frame from accidentally hitting the cleaning basket and the workpieces loaded therein during the cleaning process, thereby preventing the press frame from accidentally hitting the cleaning basket and the workpieces loaded therein from causing damage.

[0034] As an example, the frame pressure sensing alarm mechanism 6 is an infrared laser sensor, which is sensitive and fast.
