The second drive device 13 can Move along the length direction of the third drive device 14, the two ends of the second drive device 13 are respectively located on the two tracks of the third drive device 14, the third drive device 14 drives the second drive device 13 to move through the screw driven by the servo motor, the first drive device 12 can move along the length direction of the second drive device 13, the second drive device 13 is also driven by the servo motor to drive the screw transmission track, the tightening assembly 11 can move up and down along the first drive device 12, the first drive device 12 is also driven by the servo motor to drive the tightening assembly 11 up and down. The tightening assembly 11 can move in three directions: front and back, left and right, and up and down. The tightening assembly 11 can move between the screw feeder 2 and the fixture tray 3 to take the screw 6 and tighten the screw 6.

[0025] like Figure 2 , Figure 3 As shown, the tightening assembly 11 includes a mounting plate 111, a cylinder 112, an electric screwdriver 113, a support seat 114, a support plate 115, and a suction pipe 116. The cylinder 112 is fixedly mounted on the mounting plate 111, the electric screwdriver 113 is fixedly mounted on the support seat 114, the support seat 114 is slidably mounted on the mounting plate 111, the upper end of the support seat 114 is connected to the cylinder 112, the cylinder 112 can drive the electric screwdriver 113 to move up and down, so that the electric screwdriver 113 is slidably mounted on the mounting plate 111, the support seat 114 and the mounting plate 111 are connected by a slide rail, and the cylinder 112 can be extended and retracted to enable the electric screwdriver 113 to move up and down to tighten the screw 6;

[0026] More preferably, a guide rod 1141 is provided at the upper end of the support seat 114, and the guide rod 1141 passes through the cylinder 112 upward. The guide rod 1141 provides a certain guiding effect for the connection between the support seat 114 and the cylinder 112, so that the support seat 114 is more stable when moving. The guide rod 1141 is provided with a limit block 1142, and the limit block 1142 is located at the upper end of the part of the guide rod 1141 passing through the cylinder 112. The limit block 1142 provides a limit for the downward movement of the support seat 114, and limits the position where the blade 1131 of the electric screwdriver 113 can reach the lowest end.

[0027] like Figure 2 , Figure 3 As shown, the suction pipe 116 is fixedly installed on the lower end of the mounting plate 111, and the support plate 115 is installed on the lower end of the mounting plate 111. The support plate 115 extends in a horizontal direction. The support plate 115 is provided with a through hole for the suction pipe 116 or the electric screwdriver 113 to pass through. The support plate 115 is provided with a bracket 1151, and the bracket 1151 extends downward. The suction pipe 116 is installed on the bracket 1151, and the bracket 1151 is provided with a clamp that can clamp the suction pipe 116. The suction pipe 116 can adjust its height along the bracket 1151, and the height of the suction pipe 116 can be adjusted according to the length of the blade 1131 of the electric screwdriver 113.

[0028] like Figure 3 As shown, the suction pipe 116 is provided with a central channel 1162, and the cutter head 1131 is inserted into the central channel 1162. The central channel 1162 provides a guide for the cutter head 1131 to move. The central channel 1162 passes through the upper and lower end surfaces of the suction pipe 116. The side wall of the suction pipe 116 is provided with an air hole 1161, and the air hole 1161 is connected to the central channel 1162. The air hole 1161 is located near the lower end of the suction pipe 116. The air hole 1161 is connected to the air extraction device. The lower end opening of the suction pipe 116 can form a negative pressure, which can absorb the screw 6 and play a role in absorbing the screw 6. At the same time, the absorbed screw 6 is located at the lower end of the central channel 1162. After the cutter head 1131 is lowered and started, the screw 6 can be fixed on the liquid-cooled motor 4.

[0029] A suction port 1163 is provided at the lower end of the suction pipe 116. The diameter of the suction port 1163 is larger than the diameter of the central channel 1162. The suction port 1163 at the lower end of the suction pipe 116 can just accommodate the screw head 61 of the screw 6. The air hole 1161 is close to the suction port 1163. The part of the central channel 1162 above the air hole 1161 accommodates the cutter head 1131. The cutter head 1131 of the electric screwdriver 113 is at least partially located in the central channel 1162. When the electric screwdriver 113 is at the highest position, the air hole 1161 is located below the cutter head 1131, which can reduce the space for the central channel 1162 where the cutter head 1131 is located to pass the air flow, so that the suction force of the air hole 1161 can be concentrated on the suction port 1163, and the suction port 1163 can adsorb the screw 6 more stably.

[0030] More preferably, a plug 1164 is installed at the upper end of the suction tube 116, and the cutter head 1131 passes through the plug 1164. The plug 1164 serves to reduce the size of the upper end opening of the suction tube 116, thereby reducing the airflow space at the upper end opening of the suction tube 116, so that the suction force can be concentrated at the lower end opening of the suction tube 116, and the plug 1164 can replace the wear between the suction tube 116 and the cutter head 1131, serving as a consumable replacement part.

[0031] like Figure 1 , Figure 4 As shown, the screw feeder 2 is provided with a discharge channel 21 and a loading turntable 22. The screws 6 are transported to the loading turntable 22 along the discharge channel 21. The loading turntable 22 is provided with a feeding port 221. The feeding port 221 is annularly distributed on the loading turntable 22. The feeding port 221 is connected to the side wall of the loading turntable 22. Each feeding port 221 can take a screw 6 through the discharge channel 21. Each rotation of the loading turntable 22 can take out a screw 6 from the discharge channel 21. The lower end surface of the screw head 61 of the screw 6 is supported by the upper end surface of the loading turntable 22, so that the screw 6 can be fed to the feeder 21. The screw head 61 is above the loading turntable 22, and the tightening component 11 moves to the top of the screw head 61 at the corresponding position, so that the suction port 1163 covers the screw head 61 to absorb the screw head 61, and the tightening component 11 can absorb the screw 6 from the screw feeder 2. The liquid-cooled motor 4 is placed on the upper end surface of the clamp tray 3. After the tightening component 11 absorbs the screw 6, it moves to the corresponding hole position of the liquid-cooled motor 4, aligns the screw 6 with the hole position, and the electric screwdriver 113 lowers the blade 1131 to start, and tighten the screw 6 on the liquid-cooled motor 4.

[0032] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
