[0019] like Figure 1 As shown, this embodiment provides a refrigerator drawer burr scraping auxiliary device, including a conveying platform 1, a transfer mechanism 2, and a turning mechanism.

[0020] Specifically, the transfer mechanism 2 is arranged on the outer side of one end of the conveying platform 1. The table surface of the conveying platform 1 is used to convey the refrigerator drawers to the transfer mechanism 2 in sequence. Note that during the conveying process, the accommodating cavity of the refrigerator drawer is not facing upward, but facing the direction of the transfer mechanism 2. For example, Figure 2 From the perspective of , the transfer mechanism 2 is arranged on the left side of one end of the conveying platform 1, so the accommodating cavities of the refrigerator drawers are all facing the left side.

[0021] Specifically, the transfer mechanism 2 is used to take out the front refrigerator drawer on the table and deliver it to the flip mechanism, such as Figure 2 As shown, a side of the conveying platform 1 away from the transfer mechanism 2 is provided with an avoidance groove 11, and when the transfer mechanism 2 takes out the frontmost refrigerator drawer on the table, the avoidance groove 11 plays an avoidance role.

[0022] The specific implementation method of the transfer mechanism 2 is as follows: Figure 2 , Figure 3 As shown, it includes two side panels 21, a hydraulic cylinder 22, an adjustment block 23 and a slider 24. The two side panels 21 are symmetrically arranged on the top of the base, and their symmetry axes are perpendicular to the side walls of the conveying platform 1. A guide groove 211 is provided on the side panel 21. The guide groove 211 is divided into two sections. The first section is inclined downward, and the second section is horizontally arranged. The angle between the two sections is an obtuse angle. The hydraulic cylinder 22 is connected to the adjustment block 23. The adjustment block 23 is slidably arranged between the two side panels 21. The hydraulic cylinder 22 is used to move the adjustment block 23 along the symmetry axis direction of the two side panels 21. The slider 24 is movably matched with the adjustment block 23 up and down. A cylinder 241 is arranged on each side of the slider 24. The cylinder 241 is slidably matched with the corresponding guide groove 211. An inverted L-shaped plate 25 is provided on the top of the slider 24. The longitudinal section of the inverted L-shaped plate 25 is connected to the slider 24. The transverse section of the inverted L-shaped plate 25 is used to be horizontally inserted into the accommodating cavity of the refrigerator drawer.

[0023] The transfer mechanism 2 is used as follows: Figure 3 From the perspective, the cylinder 241 is now located in the second section of the guide groove 211, and the hydraulic cylinder 22 is first used to move the adjustment block 23 toward the direction of the conveyor platform 1. Since the second section of the guide groove 211 is horizontal, the slider 24 and the inverted L-shaped plate 25 thereon only move horizontally with the adjustment block 23 during this process; when the transverse section of the inverted L-shaped plate 25 is inserted into the accommodating cavity of the refrigerator drawer and is about to contact the inner bottom of the refrigerator drawer, the cylinder 241 is now located at the angle between the two sections of the guide groove 211; the hydraulic cylinder 22 is used to continue to move the adjustment block 23 toward the direction of the conveyor platform 1. Since the first section of the guide groove 211 is inclined, the slider 24 and the inverted L-shaped plate 25 thereon not only move horizontally with the adjustment block 23 during this process, but the slider 24 and the inverted L-shaped plate 25 thereon also move upward, thereby causing the refrigerator drawer to move upward and tilt, and to separate from the conveyor platform 1.

[0024] Specifically, Figure 1 , Figure 2 As shown, the flip mechanism includes a linear stroke component 31, a first motor 33 and two symmetrically arranged clamping members 32. The linear stroke component 31 is used to adjust the spacing between the two vertical plates 34. One implementation of the linear stroke component 31 is: it includes a second motor 311, a screw rod 312 and a box body 313. The box body 313 is opened at the top, the screw rod 312 is rotatably arranged in the box body 313, and the long axis of the screw rod 312 is parallel to the conveying direction of the conveying platform 1. The second motor 311 is used to drive the screw rod 312. The threads at both ends of the screw rod 312 are opposite. Blocks 341 are provided at the bottom of the two vertical plates 34. The blocks 341 are slidably matched with the box body 313 and are threadedly matched with the corresponding positions of the screw rod 312. The clamping members 32 are rotatably arranged on the corresponding inner walls of the vertical plates 34. The clamping members 32 are used to clamp the side walls of the refrigerator drawer. The first motor 33 is arranged on the outer wall of one of the vertical plates 34, and its output shaft is connected to one of the clamping members 32.

[0025] The method of using the flipping mechanism is as follows: use the transfer mechanism 2 to make the refrigerator drawer move upward and tilted, and leave the conveying platform 1, and stop when the refrigerator drawer is located between the two clamps 32, and use the second motor 311 to drive the screw rod 312 to cause the two clamps 32 to gather together, thereby clamping and fixing the side wall of the refrigerator drawer; then use the first motor 33 to drive one of the clamps 32, so as to flip the refrigerator drawer so that the staff can scrape off the burrs.

[0026] In order to improve the stability of the clamping member 32 in clamping the refrigerator drawer, the present embodiment takes the following measures: the clamping member 32 includes a connecting plate 321 and two clamping plates 322, the connecting plate 321 is rotatably arranged on the inner wall of the corresponding vertical plate 34, the two clamping plates 322 are arranged on the inner wall of the connecting plate 321, and a plurality of vacuum adsorption holes are provided on the clamping plate 322.

[0027] More specifically, in order to prevent impurities from falling into the box 313 during the process of scraping off the burrs, the present embodiment adopts the following measures: Figure 1 As shown, the linear travel assembly 31 also includes a protective plate 314, which is mounted above the box body 313, and is located between two vertical plates 34. The top of the protective plate 314 is in an arc shape. When the vertical plates 34 are close to the protective plate 314, the clamping plate 322 just fixes the side wall of the refrigerator drawer.

[0028] The above embodiments are only used to illustrate the technical ideas and features of the utility model, and are not intended to be the only or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
