[0025] As an improvement, as Figure 3 , Figure 7 shown, the positioning component 33 includes: The X-axis module 331 is installed at the lower part of the carrier plate 102; The sliding frame 332 is arranged on the upper part of the X-axis module 331 and is used to cooperate with the X-axis module 331 to move along the X-axis direction; The Y-axis module 333 is installed at the upper end of the sliding frame 332; The rotating shaft 334 is arranged on one side of the Y-axis module 333, and a motor for driving the rotating shaft 334 to rotate is provided at the lower end of the rotating shaft 334; The positioning platform 335 is fixedly connected to the upper end of the rotating shaft 334.

[0026] Furthermore, positioning areas corresponding to the material taking gripper 26 and the material placing gripper 25 one by one are provided at the upper end of the positioning platform 335.

[0027] As an improvement, as Figure 4 shown, the conveying unit 1 includes: The feeding assembly line 11; The feeding end station flow 13 is arranged at the corresponding position of the feeding assembly line 11 and the handling unit 2, and is used for supplying the middle frames of electronic products to the material taking gripper 26; The buffer four-station flow 12 is arranged at the upper end of the feeding assembly line 11, and is used for conveying the middle frames of electronic products put down by the material placing gripper 25 out of the housing 100; An outlet 101 for discharging the middle frames of electronic products conveyed by the buffer four-station flow 12 is provided on one side of the housing 100.

[0028] It should be added that in the present invention, every time the handling unit 2 completes one material taking and placing operation, the feeding assembly line 11 advances once, ensuring that the conveying of the middle frames of electronic products by the feeding assembly line 11 and the material taking and placing of the handling unit 2 maintain the same rhythm; It should also be added that a motor for driving the take-up roller 137 to rotate is provided at the rear end of the take-up roller 137 of the present invention, for driving the non-woven fabric 316 to continuously feed.

[0029] It should be noted that: in the specific implementation process of the present invention, as Figure 3 , Figures 5 - 7 shown, initially, the positioning platform 335 is close to the support 21, and the middle frames of electronic products that need to be wiped and cleaned are sequentially placed on the feeding assembly line 11 in a conveying state. The feeding assembly line 11 conveys the middle frames of electronic products from the outside of the housing 100 to the inside of the housing 100 and directly below the material taking gripper 26. The second lead screw module 24 drives the material taking gripper 26 to move downward to the outside of the middle frame of the electronic product and clamp the middle frame of the electronic product. Subsequently, the second lead screw module 24 moves upward to pick up the middle frame of the electronic product. The first lead screw module 22 drives the second lead screw module 24 to move through the slide plate 23. The second lead screw module 24 moves the middle frame of the electronic product to directly above the positioning platform 335 through the material taking gripper 26 and places the middle frame of the electronic product on the positioning platform 335. The positioning platform 335 positions the middle frame of the electronic product; As Figure 3 , Figure 7 shown, subsequently, the X-axis module 331 drives the sliding carriage 332 to move along the +X-axis direction. The sliding carriage 332, under the action of the Y-axis module 333 and the rotating shaft 334, moves the positioning platform 335 from the handling unit 2 to directly below the cleaning head 314. The third lead screw module 312 is started, and the third lead screw module 312 drives the mounting panel 3121 to move downward along the fixed plate 311. The mounting panel 3121 drives the cleaning head 314 to press the non-woven fabric 316 against the middle frame of the electronic product located within the positioning platform 335. The Y-axis module 333 is started, and the Y-axis module 333 drives the positioning platform 335 to move along the Y-axis direction through the rotating shaft 334, causing the middle frame of the electronic product located at the upper end of the positioning platform 335 to slide relative to the non-woven fabric 316 at the lower end of the cleaning head 314, ensuring that the cleaning head 314 can evenly wipe and clean the middle frame of the electronic product through the non-woven fabric 316, with accurate wiping and consistent wiping trajectories each time, avoiding damage to the components on the middle frame of the electronic product; As Figures 8 - 9 shown, in the present invention, the peristaltic pump 322 extracts the alcohol in the alcohol barrel 323 in segments and squeezes it into the delivery pipe 324. The delivery pipe 324 quantitatively applies the alcohol to the outer side of the non-woven fabric 316 through the alcohol application head 314, and when the non-woven fabric 316 is fed, the alcohol on the outer side of the non-woven fabric 316 is wiped onto the surface of the middle frame of the electronic product under the extrusion of the cleaning head 326, ensuring that the alcohol wiping amount for each middle frame remains equal, avoiding the impact on the next workstation due to excessive or insufficient alcohol wiping; As Figures 3 - 7 shown, after the alcohol wiping is completed, the X-axis module 331 moves the positioning platform 335 from directly below the cleaning assembly 31 to directly below the picking gripper 26. Subsequently, the motor at the lower end of the rotating shaft 334 is started, and the motor drives the positioning platform 335 to rotate through the rotating shaft 334. The positioning platform 335 switches the middle frame of the electronic product that has been cleaned and is located directly below the picking gripper 26 to directly below the placing gripper 25. At this time, the second lead screw module 24 drives the placing gripper 25 to pick up the middle frame of the electronic product on the positioning platform 335. The first lead screw module 22 is started, and the first lead screw module 22 drives the second lead screw module 24 to place the middle frame of the electronic product taken out by the placing gripper 25 at the buffer four-station flow 12. At the same time, the picking gripper 26 picks up the middle frame of the electronic product that has not been wiped and cleaned at the feeding-end station flow 13, and the above-mentioned wiping and cleaning operation process is performed again on the next group of middle frames of the electronic products, which will not be elaborated; As Figure 1 , Figure 4As shown, in the present invention, the feeding pipeline 11 is divided into a feeding end station flow 13 and a buffer four-station flow 12. The buffer four-station flow 12 has four buffer positions, ensuring that the alcohol is fully volatilized in the buffer four-station flow 12 before being conveyed out at the discharge port 101, further reducing the irritation of alcohol to the workers.
