DETAILED DESCRIPTION

[0023] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will appreciate that many technical details are provided in various embodiments of the present invention to facilitate a better understanding of the present application. However, even without these technical details and the various variations and modifications based on the following embodiments, the technical solutions claimed in the claims of this application can be achieved.

[0024] Example 1

[0025] See also Figure 1-Figure 3As shown, an automated welding equipment for the production of a sweeping robot includes an operating table 1, a mounting frame 2 is installed on the operating table 1, a hydraulic cylinder 3 is installed on the mounting frame 2, a welding head 4 is installed at the bottom of the hydraulic cylinder 3, a loading device 5 is provided on the operating table 1, and the loading device 5 includes two ratchets 51, the two ratchets 51 are installed on the inner wall of the operating table 1, one of the ratchet wheels 51 is connected to a telescopic rod 52, and the other ratchet wheel 51 is connected to a rotating rod 53, and the rotating rod 53 rotates in opposite directions to the telescopic rod 52, an upper turntable 57 is installed on the rotating rod 53, and a lower turntable 56 is provided on the telescopic rod 52, two gears 54 are respectively installed on the two ratchets 51, a fork frame 55 is slidably installed on the operating table 1, and two racks are provided on the fork frame 55, and the two gears 54 are respectively engaged with the racks on the two fork frames 55. When the hydraulic cylinder 3 moves upward, the hydraulic cylinder 3 drives the slide bar 511 to slide upward on the mounting frame 2, and the slide bar 511 drives the fork frame 55 to move backward through the link 510. When the fork frame 55 moves, the two flat teeth drive the two gears 54 to rotate in the opposite direction. When the two gears 54 rotate, the rotating rod 53 and the telescopic rod 52 are driven to rotate in the opposite direction respectively through the two ratchets 51. The rotating rod 53 and the telescopic rod 52 drive the upper turntable 57 and the lower turntable 56 to rotate in the opposite direction respectively. Due to the steering restriction of the two ratchets 51 on the rotating rod 53 and the telescopic rod 52, when the hydraulic cylinder 3 moves downward, the fork frame 55 cannot drive the ratchet 51 to rotate through the gear 54. There are multiple loading ports, and the multiple loading ports are in a circular array. There are multiple loading platforms on the lower turntable 56, and the multiple loading platforms are in a circular array. The number of loading ports is the same as the number of loading platforms. The parts located above are placed on the loading ports on the upper turntable 57, and the parts located below are placed on the loading platform of the lower turntable 56. At this time, the two parts located below the welding head 4 are in an upper and lower superimposed state. A plurality of convex balls 58 are installed at the bottom of the lower turntable 56, and a resistance rod 59 is installed on the operating table 1. The resistance rod 59 is located on the movement trajectory of the plurality of convex balls 58. The plurality of convex balls 58 are respectively located below the plurality of loading platforms on the lower turntable 56. When one of the convex balls 58 contacts the resistance rod 59, the resistance rod 59 lifts the lower turntable 56 through the convex ball 58. When the convex ball 58 does not contact the resistance rod 59, the lower turntable 56 drops by its own gravity.

[0026] In this embodiment, the feeding device 5 is set up so that the upper turntable 57 and the lower turntable 56 can rotate in opposite directions while the hydraulic cylinder 3 is moving. Through the cooperation of the upper turntable 57 and the lower turntable 56, multiple groups of parts to be welded can be placed at one time. After a group of parts is welded, the upper turntable 57 rotates to transport them to the next process, which reduces the frequency of workers placing parts and improves work efficiency.

[0027] Example 2

[0028] See also Figure 4-Figure 5 As shown, the operating table 1 is provided with a cooling component 6, which includes an airbag 62, which is installed on the operating table 1, and an air pipe 63 is installed on the airbag 62. An air cooler 64 is installed on the operating table 1. A pressure block 61 is slidably installed on the operating table 1, and a fork frame 55 is connected to the pressure block 61. An air outlet is provided on the air cooler 64. When the fork frame 55 moves backward, the fork frame 55 drives the pressure block 61 to move, and the pressure block 61 squeezes the airbag 62 when it moves. After the airbag 62 is squeezed, the air inside it is transported to the air cooler 64 through the air pipe 63, and the air cooler 64 blows the wind to the parts in front through the air outlet.

[0029] The operating table 1 is provided with a protective component 7, which includes two inclined slide frames 71, and the two inclined slide frames 71 are respectively installed on both sides of the slide bar 511. Two movable rods 72 are rotatably installed on both sides of the mounting frame 2, and two protective covers 73 are respectively installed on the two movable rods 72. The two movable rods 72 are respectively slidably connected to the inner walls of the two inclined slide frames 71. When the hydraulic cylinder 3 moves upward, the slide bar 511 drives the two protective covers 73 to close through the cooperation of the two inclined slide frames 71 and the two movable rods 72, thereby protecting the welding head 4.

[0030] In this embodiment, the cooling component 6 is provided so that after welding is completed, the parts are transported to the front of the air cooler 64 through the upper turntable 57. The air cooler 64 cools the parts with air, accelerates the cooling speed of the parts, makes the parts take shape faster, and prevents workers from accidentally getting burned when taking the parts; through the provision of the protective component 7, when the hydraulic cylinder 3 drives the welding head 4 to move downward, the two protective covers 73 can be automatically deployed without affecting the welding operation. When the hydraulic cylinder 3 drives the welding head 4 to move upward and reset, the two protective covers 73 can be automatically closed to protect the welding head 4 inside, thereby preventing the welding head 4 from being damaged by external force when not working, and also preventing dust from being adsorbed on the welding head 4, keeping the welding head 4 clean.

[0031] When the automatic welding equipment for the production of a sweeping robot of the present invention is used, the staff will separate the two parts that need to be welded together, place the part located on the upper side on the loading port on the upper turntable 57, and place the part located on the lower side on the loading platform of the lower turntable 56. At this time, the two parts located below the welding head 4 are in an upper and lower superimposed state. At this time, the hydraulic cylinder 3 is started, and the hydraulic cylinder 3 drives the welding head 4 to move downward. After the welding head 4 moves downward until it contacts the parts, the hydraulic cylinder 3 stops moving, and the welding head 4 performs the welding operation. After the welding operation is completed, the hydraulic cylinder 3 drives the welding head 4 upward. When the hydraulic cylinder 3 moves upward, the hydraulic cylinder 3 drives the slide bar 511 to slide upward on the mounting frame 2. The slide bar 511 drives the fork frame 55 to move backward through the connecting rod 510. When the fork frame 55 moves, the two flat teeth drive the two gears 54 to rotate in the opposite direction. When the two gears 54 rotate, they drive the rotating rod 53 and the telescopic rod 52 to rotate in the opposite direction respectively through the two ratchets 51. The rotating rod 53 and the telescopic rod 52 drive the upper turntable 57 and the lower turntable 56 to rotate in the opposite direction respectively. When the lower turntable 56 rotates, the lower turntable 56 drives multiple convex balls 58 to rotate. When one of the convex balls 58 contacts the resistance rod 59, , the contact rod 59 lifts the lower turntable 56 through the convex ball 58. When the convex ball 58 is no longer in contact with the contact rod 59, the lower turntable 56 falls by its own gravity, so that when the lower turntable 56 rotates, the lower turntable 56 will fall. When the lower turntable 56 stops rotating, the lower turntable 56 rises. Since the two parts have been welded together, when the lower turntable 56 falls, the parts are separated from the contact with the lower turntable 56. The welded parts are gradually transported to the next process through the rotation of the upper turntable 57. When the upper turntable 57 and the lower turntable 56 stop rotating, the two unwelded parts are stacked together and wait. During welding, due to the steering restrictions of the two ratchets 51 on the rotating rod 53 and the telescopic rod 52, when the hydraulic cylinder 3 moves downward, the fork frame 55 cannot drive the ratchet 51 to rotate through the gear 54. Through the setting of the loading device 5, the upper turntable 57 and the lower turntable 56 can rotate in opposite directions while the hydraulic cylinder 3 moves. Through the cooperation of the upper turntable 57 and the lower turntable 56, the effect of placing multiple groups of parts to be welded can be achieved at one time. After a group of parts is welded, the upper turntable 57 transports them to the next process by rotating, which reduces the frequency of workers placing parts and improves work efficiency.

[0032] When the fork frame 55 moves backward, the fork frame 55 drives the pressure block 61 to move. When the pressure block 61 moves, it squeezes the air bag 62. After the air bag 62 is squeezed, the air inside the air bag 62 is transported to the air cooler 64 through the air pipe 63. The air cooler 64 blows the wind to the parts in front through the air outlet to cool the parts. Through the setting of the cooling component 6, after the welding is completed, the parts are transported to the front of the air cooler 64 through the upper turntable 57. The air cooler 64 cools the parts with air, speeds up the cooling speed of the parts, makes the parts take shape faster, and avoids burns when the staff takes the parts. When the slide bar 511 follows the hydraulic cylinder 3 to move downward, the slide bar 511 drives the two inclined slide racks 71 to move downward. When the two inclined slide racks 71 move downward, they respectively carry The two movable rods 72 are moved to rotate in opposite directions away from each other, and the two movable rods 72 respectively drive the two protective covers 73 to open, which does not affect the welding operation of the welding head 4. When the hydraulic cylinder 3 moves upward, the slide rod 511 drives the two protective covers 73 to close through the cooperation of the two inclined slide frames 71 and the two movable rods 72. Through the setting of the protective component 7, when the hydraulic cylinder 3 drives the welding head 4 to move downward, the two protective covers 73 can be automatically unfolded without affecting the welding operation. When the hydraulic cylinder 3 drives the welding head 4 to move upward and reset, the two protective covers 73 can be automatically closed to protect the welding head 4 inside it, to prevent the welding head 4 from being damaged by external force when not working, and to prevent dust from being adsorbed on the welding head 4, thereby keeping the welding head 4 clean.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
