The bearing frame 30 can provide bearing capacity for the parts and store the parts at intervals to prevent damage to the parts caused by stacking. The height of the bearing frame 30 is changed by the lifting assembly 20, making it more convenient to take and place the parts and improving the repair efficiency.

[0026] In one possible implementation, referring to Figure 3 , the lifting assembly 20 includes two racks 21, two sliding members 22, a rotating rod 23, and a rotating drive member 24. The two racks 21 are vertically fixedly connected to the two upright columns 11, respectively. The two sliding members 22 are arranged below the bearing frame 30 and are slidably connected to the two upright columns 11, respectively. The first gear 221 is rotatably arranged on each of the two sliding members 22, and the two first gears 221 are engaged and rolled on the two racks 21, respectively. The rotating rod 23 is rotatably connected to the bearing frame 30 at both ends, and the two ends of the rotating rod 23 are drivingly connected to the two gears, respectively. The rotating drive member 24 is arranged on the bottom wall of the bearing frame 30, and the output end is connected to the rotating rod 23.

[0027] It should be noted that the first gear 221 is rotatably arranged on the sliding member 22 and connected with the rack 21, so that the two sliding members 22 are slidably connected to the two upright columns 11 and are lifted together. The rotating drive member 24 is arranged in the middle of the bottom wall of the bearing frame 30, so as to avoid uneven stress on the overall structure caused by the weight of the rotating drive member 24. The rotating rod 23 is horizontally arranged, the middle part of the rotating rod 23 is connected to the output end of the rotating drive member 24, the two ends are drivingly connected to the first gear 221, and the two ends of the rotating rod 23 are rotatably arranged on the bearing frame 30. This arrangement avoids the output end of the rotating drive member 24 from increasing in torque due to the suspension of one end of the horizontally arranged rotating rod 23, and avoids damage to the rotating drive member 24.

[0028] In one possible implementation, referring to Figure 3The second gear 222 is coaxially connected with the first gear 221, and the first gear 221 is meshed with the rack 21. The rotating rod 23 is above the second gear 222 and is provided with the helical teeth 231. The rotating rod 23 with the helical teeth 231 forms a worm gear structure with the second gear 222. The rotating rod 23 is rotated under the driving of the rotating driving member 24. The helical teeth 231 drive the second gear 222 to rotate. The second gear 222 rotates synchronously with the first gear 221 and walks on the rack 21.

[0029] It should be noted that the first gear 221 is coaxially connected with the second gear 222, and the first gear 221 is meshed with the rack 21. The rotating rod 23 is above the second gear 222 and is provided with the helical teeth 231. The rotating rod 23 with the helical teeth 231 forms a worm gear structure with the second gear 222. The rotating rod 23 is rotated under the driving of the rotating driving member 24. The helical teeth 231 drive the second gear 222 to rotate. The second gear 222 rotates synchronously with the first gear 221 and walks on the rack 21.

[0030] In a possible implementation, please refer to Figure 3 The helical teeth 231 at two ends of the rotating rod 23 are opposite in rotation direction.

[0031] It should be noted that the helical teeth 231 at two ends of the rotating rod 23 in the same lifting assembly 20 are opposite in rotation direction. The helical teeth 231 at two ends of the rotating rod 23 are symmetrically arranged relative to the rotating driving member 24. The rotating rod 23 with the helical teeth 231 opposite in rotation direction makes one of the second gears 222 rotate clockwise, and the other second gear 222 rotate counterclockwise, so as to offset the axial movement between the two second gears 222, avoid the rotation of the two second gears 222 around the rotating driving member 24, ensure the simultaneous rising or falling of the two ends of the lifting assembly 20, and realize the storage of the parts.

[0032] In a possible implementation, please refer to Figure 2 The carrier frame 30 has a carrier plate 31 and a support frame 32.

The support frames 32 provide a placement space below the bearing plate 31, so that even if each bearing frame 30 does not store parts, the placement space between the support frames 32 and the adjacent bearing plate 31 can be used to store parts, thereby improving the space utilization. The first gear 221 is rotatably connected to the sliding member 22, and the lowest point of the gear during rotation is higher than the lower surface of the support frame 32, which can ensure the abutment of the support frame 32 and the lower bearing frame 30, and avoid scratching the bearing frame 30 below the support frame 32 by the gear, thereby preventing damage to the bearing frame 30 and the gear, and ensuring that the device can smoothly complete the storage and lifting of the parts. The upper surface of the bearing plate 31 can be surrounded by a guardrail, and the guardrail can be inclined, with the top end of the guardrail inclined toward the center of the bearing plate 31, and the inclination angle can be 3°, which can prevent the parts from sliding off the bearing plate 31 when placed; the guardrail is open on one side to facilitate the removal of parts from the bearing plate 31.
