[0002] Auto parts refer to auto accessories, which are the various units that make up the entire car and a product that serves the car. There are many types of auto parts. With the improvement of people's living standards, people's consumption of cars is increasing, and the market for auto parts is getting bigger and bigger. In recent years, auto parts manufacturers are also developing rapidly. In the production process, auto parts need to be welded with the help of welding equipment to meet the conditions for car use.

[0003] At present, in the process of processing small auto parts, workers need to manually place the auto parts one by one at the welding point and then merge them with the nuts. The view of auto parts and nuts is as follows: Figure 9 As shown, driving the welding gun for welding is a long-term, frequent and repeated operation, which can easily cause errors among workers, resulting in personal injury caused by the welding gun. At the same time, high-temperature welding between the welding gun and the welding point can easily produce a large amount of welding slag dust and harmful gases. If the dust is not cleaned in time, it will affect the subsequent welding of parts. At the same time, harmful gases aggravate the environmental pollution at the processing location, and long-term inhalation by workers will affect their health. Summary of the Invention

DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0041] The present invention discloses an automobile parts welding machine which is mainly used for welding small automobile parts and nuts.

[0042] Reference Figure 1 and Figure 2 A welding machine for automobile parts comprises a frame assembly 1, wherein a feeding assembly 2 for conveying parts is provided on the left side of the upper end of the frame assembly 1; a storage linkage mechanism 3 for storing unprocessed parts is provided in the middle part of the upper end of the frame assembly 1; a storage mechanism 4 for storing nuts is provided on the right side of the upper end of the frame assembly 1; a rotary welding mechanism 5 for welding automobile parts is provided on the rear side of the storage mechanism 4; a driving mechanism 6 for driving loading and unloading is provided on the left side of the lower end of the frame assembly 1; a unloading assembly 7 for unloading parts is connected to the right side of the driving mechanism 6; a cleaning mechanism 8 for cleaning welding slag dust and purifying harmful gases is provided on the right side of the unloading assembly 7, and the frame assembly 1 comprises a workbench 101, and a feeding trough 102 is provided through the middle of the workbench 101.

[0043] In this embodiment: first, a part of the small automotive parts are placed in the storage linkage mechanism 3, and a part of the nuts are placed inside the storage mechanism 4 to play a pre-storage role. Then, the driving mechanism 6 is started to drive the feeding assembly 2 to push the automotive parts previously prepared in the feeding trough 102 to move to the right. At the same time, the feeding assembly 2 drives the storage linkage mechanism 3 to prepare for the next group of automotive parts, prompting a group of small parts in the storage linkage mechanism 3 to fall into the feeding trough 102, which is convenient for the feeding assembly 2 to push. While the driving mechanism 6 drives the feeding assembly 2, the driving mechanism 6 synchronously drives the unloading assembly 7. Unload a group of previously welded small automotive parts on the unloading column 702 by rotating it, and move a group of free unloading columns 702 to the lower right side of the workbench 101 to facilitate the placement of unprocessed parts. At this time, the feeding component 2 pushes the parts to the right until they are pushed to the upper end of the unloading column 702, and the feeding component 2 drives the storage linkage mechanism 3 in the process of linking the storage mechanism 4 to promote automatic feeding of nuts, ensuring that a group of nuts fall on the upper end position of the parts pushed to the upper end of the unloading column 702. At this time, the nuts and parts are merged and welding is carried out. Start the rotary welding mechanism 5 to drive the laser gun 504 to weld the contact point between the nut and the component in a circle. During the welding process, the high temperature produces harmful gases and welding slag dust. Since the unloading column 702 is connected to the cleaning mechanism 8, the harmful gases are collected, purified and discharged by the air pump to ensure that the environmental air indicators are within a safe range and the physical and mental health of the staff is guaranteed. The welding slag dust is collected in a centralized manner to reduce the subsequent cleaning of waste slag one by one and ensure the normal operation of the welding. After the welding of the nut and the component is completed, the driving mechanism 6 is started to synchronously drive the feeding component 2 and the unloading component 7. The feeding component 2 pushes the prepared parts to be loaded and at the same time drives the stocking linkage mechanism 3 to prepare for the next group of parts, and drives the stocking linkage mechanism 3 to drive the storage mechanism 4 to feed the parts. The unloading assembly 7 rotates and unloads the parts that have been dry-welded, and moves to a new group of unloading columns 702 to the lower right side of the workbench 101 for processing the next group of parts. In this way, the processing is repeated continuously. The staff only needs to intermittently add automobile parts and nuts to the inside of the stocking linkage mechanism 3 and the storage mechanism 4, and there is no need to manually place the parts on the welding position repeatedly, thereby reducing contact with welding and improving the safety of the staff.

[0044] In the first embodiment, considering the need for parts preparation and loading and pushing, the specific operations are as follows:

[0045] Reference Figure 1 、 Figure 2 and Figure 3When the material is stored in the storage box 301, the material storage box 301 is fixed with a lifting mechanism 302, and the lifting mechanism 302 is fixed with a lifting mechanism 303. The lifting mechanism 302 is fixed with a lifting mechanism 303 and a lifting mechanism 303 is fixed with a lifting mechanism 303.

[0046] When the loading is complete, the movable rod 203 is rotated in the square groove 202 to move in an annular manner, prompting the pushing plate 201 to push the feeding trough 102 to the right, pushing the parts prepared in the feeding trough 102 to the right. During the pushing process, the right front end of the pushing plate 201 contacts the connecting rod 306, prompting the connecting rod 306 to slide to the right along the slide groove 103 on the workbench 101, thereby driving the limiting plate 305 and the sliding rod 303 to slide to the right in the material storage box 301. The first spring 304 on the outer surface of the sliding rod 303 is forced to shrink by the sliding rod 303 sliding to the right. At the same time, the limiting plate 305 synchronously drives the partition plate 307 and the top column 308 to move to the right. At this time, the lower end of the material storage trough 302 inside the material storage box 301 is opened, and the parts stored in the material storage trough 302 fall and fall on the upper surface of the pushing plate 201. At this time, the right front end of the pushing plate 201 After the parts pushed from the end are in place, the movable rod 203 moves in a circular motion in the square groove 202, and the pushing plate 201 moves to the left in the feeding trough 102. At this time, the pushing plate 201's resistance to the connecting rod 306 to the right disappears, and the sliding bar 303, the limiting plate 305, the connecting rod 306, the partition plate 307 and the top column 308 are reset by the first spring 304. The limiting plate 305 moves to the left at the lower end of the storage box 301 to block the storage trough 302. At this time, the upper parts of the storage trough 302 are blocked, and one group falls on the upper end of the pushing plate 201. During the displacement of the pushing plate 201 to the left, the upper parts of the pushing plate 201 are resisted by the workbench 101 and remain in place. Subsequently, after the pushing plate 201 is withdrawn, the parts fall into the feeding trough 102 and serve as preparation parts, which is convenient for the processing parts when the pushing plate 201 is pushed to the right again.

[0047] In the first embodiment, it is necessary to feed nuts and combine them with parts. Considering that a set of parts is matched with a set of nuts, the specific operation is as follows:

[0048] Reference Figure 1 、 Figure 4 and Figure 5 In a preferred embodiment, the storage mechanism 4 includes a storage column 401 connected to the right side of the storage box 301, a through groove 402 is opened through the middle of the storage column 401, a card slot 403 is opened at the lower left end of the storage column 401, a fixed plate 404 is provided at the lower right end of the storage column 401, a sliding plate 405 is slidably connected to the middle of the fixed plate 404, a conduction rod 408 is connected to the front and rear ends of the left side of the sliding plate 405, the end of the conduction rod 408 away from the sliding plate 405 is connected to a cylinder 407, and a second spring 406 is connected to the right side of the cylinder 407.

[0049] In this embodiment, when the limiting plate 305 synchronously drives the partition 307 and the top column 308 to move to the right, the partition 307 is clamped into the inner groove 403 of the storage column 401, blocking the through groove 402 inside the storage column 401. At the same time, the top column 308 contacts the cylinder 407, causing the sliding plate 405 to move to the right. The second spring 406 contracts, and the through groove 402 originally blocked by the sliding plate 405 is opened. The internal nut slides down and falls on the blocked partition 307. At this time, the partition 307 and the top column 308 move to the right. When the left reset displacement occurs, the top force of the cylinder 407 disappears, and the cylinder 407 and the sliding plate 405 are reset by the second spring 406, which blocks the through groove 402, preventing the upper thread from falling, and causing a set of nuts to be placed between the sliding plate 405 and the partition 307. After the partition 307 is pulled out of the slot 403, the set of nuts that originally fell on the partition 307 slides down and combines with the parts. Therefore, when a set of parts is pushed, a set of nuts will fall down to match, thereby reducing the phenomenon of repeated picking by staff and improving the automation effect of loading.

[0050] In the first embodiment, considering that the nut and the component need to be welded together, the specific operation is as follows:

[0051] Reference Figure 1 、 Figure 2 and Figure 4 In a preferred embodiment, the rotary welding mechanism 5 includes a wheel disc assembly 501 whose bearing is connected to the outer surface of the upper end of the storage column 401, a first motor 502 is connected to the lower rear end of the wheel disc assembly 501, a turntable 503 is connected to the lower front end of the wheel disc assembly 501, and a laser gun 504 is installed on the outer surface of the turntable 503.

[0052] In this embodiment, the first motor 502 is started to drive the Falun disk assembly 501 to transmit the turntable 503, causing the turntable 503 to rotate in a circle around the storage column 401, thereby driving the laser gun 504 to move and perform a circle of high-temperature welding on the contact point between the component and the nut.

[0053] In the first embodiment, considering that loading and unloading need to be driven in order to improve the automation effect, the specific operations are as follows:

[0054] Reference Figure 1 and Figure 6 In a preferred embodiment, the driving mechanism 6 includes a small gear 601 connected to the lower end of the movable rod 203, the lower end of the small gear 601 is connected to the second motor 602, the right side of the small gear 601 is meshed with a large gear 603, the lower end of the large gear 603 is connected to a bevel gear set 604, and the right side of the bevel gear set 604 is connected to a rotating shaft 605.

[0055] In this embodiment: first, the second motor 602 is started to drive the small gear 601 to drive the movable rod 203 to move in a circular motion, thereby realizing the phenomenon of the push plate 201 being displaced left and right in the feed trough 102, which plays a role in pushing the material. At the same time, the small gear 601 synchronously drives the large gear 603 to drive the bevel gear group 604 to rotate the linkage shaft 605, prompting the outer cylinder 701 to rotate, thereby realizing the position change of multiple groups of unloading columns 702, and rotating and pushing the processed parts on the unloading columns 702 for unloading, and rotating the remaining unloading columns 702 to the processing position at the lower right side of the workbench 101 for subsequent parts processing.

[0056] In the first embodiment, considering that the parts and nuts need to be placed in a certain position for welding, the specific operations are as follows:

[0057] Reference Figure 1 、 Figure 6 and Figure 7 In a preferred embodiment, the unloading component 7 includes an outer cylinder 701 connected to the right side of the rotating shaft 605, a unloading column 702 is provided on the outer surface of the outer cylinder 701, a ventilation groove 703 is opened through the middle of the unloading column 702, and a bar grid 704 is provided at the opening of the unloading column 702 away from the outer cylinder 701, and a limiting protrusion 705 is fixedly connected in the middle of the bar grid 704.

[0058] In this embodiment: when the push plate 201 pushes the parts prepared by the feeding trough 102 to the right, the parts are pushed to the upper end of the bar grid 704 of the unloading column 702, and the circular holes on the parts are sleeved on the limiting protrusions 705, so that they are stably placed on the upper end of the bar grid 704. At the same time, the ventilation grooves 703 are constantly sucking, playing a certain adsorption role, and the lower end of the storage column 401 is aligned with the limiting protrusions 705, so that the nut falls on the limiting protrusions 705 after sliding down, and is combined with the circular holes on the parts, which is convenient for finished product processing. After welding is completed, the rotating shaft 605 drives the outer cylinder 701 to rotate, The processed parts are rotated and pushed to the corresponding position of the through hole 803 on the inner cylinder 801. Another set of empty unloading columns 702 are prepared for the next group of parts processing at the right side of the workbench 101. The processed parts are at the corresponding position of the through hole 803 on the inner cylinder 801. The air pump is used to suck the processed parts from the through hole 803 to ensure that the processed parts continue to have an adsorption effect, preventing the outer cylinder 701 from rotating and the angle of the unloading column 702 from changing, causing the processed parts to directly break away from the upper end of the fence 704 and fall from a high place and collide, resulting in the separation of the nut and the parts.

[0059] In the first embodiment, considering that welding slag dust and harmful gases generated during the welding of parts and nuts need to be treated, the specific operations are as follows:

[0060] Reference Figure 1 and Figure 8 In a preferred embodiment, the cleaning mechanism 8 includes an inner cylinder 801 movably connected to the inner part of the outer cylinder 701, a ventilation port 802 is provided on the upper end of the left outer surface of the inner cylinder 801, a through hole 803 is provided on the rear side of the left outer surface of the inner cylinder 801, a purification net 804 is provided on the right side of the inner cylinder 801, and a waste box 805 is connected to the right side of the lower end of the inner cylinder 801.

[0061] In this embodiment: during the high-temperature welding process of parts and nuts by the laser gun 504, the generated welding slag dust and harmful gases are exhausted by the air pump and enter the inner cylinder 801 through the ventilation slot 703 inside the unloading column 702 through the ventilation port 802. At the same time, the air pump exhaust can exert suction on the parts placed on the upper surface of the bar grid 704 above the unloading column 702, thereby increasing the stability of the placement. Moreover, when the outer cylinder 701 is rotating with the unloading column 702, the inner cylinder 801 always remains stationary, thereby ensuring that only the unloading column 702 at the ventilation port 802 on the outer cylinder 701 has strong suction. At this time, welding slag dust and harmful gases enter the inner cylinder 801. After the harmful gases pass through the purification net 804, they are purified and discharged through the purification net 804, thereby ensuring the environmental safety of the working area and the physical and mental health of the staff. At the same time, the welding slag dust is blocked by the purification net 804 and falls into the waste box 805 for centralized collection, ensuring the operation of the processing while reducing the subsequent manual cleaning phenomenon of the staff.

[0062] Among them, the automobile parts and nuts are shown as follows Figure 9 shown.

[0063] Working principle: When in use, first place some small auto parts in the storage linkage mechanism 3, and place some nuts in the storage mechanism 4 to pre-store them. Then start the driving mechanism 6 to drive the feeding assembly 2 to push the auto parts previously prepared in the feeding trough 102 to the right. At the same time, the feeding assembly 2 drives the storage linkage mechanism 3 to prepare for the next group of auto parts, prompting a group of small parts in the storage linkage mechanism 3 to fall into the feeding trough 102, which is convenient for the feeding assembly 2 to push. When the driving mechanism 6 drives the feeding assembly 2, the driving mechanism 6 synchronously drives the unloading assembly Part 7, unload a group of welded small automotive parts on the previous unloading column 702 by rotating it, and turn a group of empty unloading columns 702 to the lower right side of the workbench 101 to facilitate the placement of unprocessed parts. At this time, the feeding component 2 pushes the parts to the right until they are pushed to the upper end of the unloading column 702, and the feeding component 2 drives the storage linkage mechanism 3 in the process of linking the storage mechanism 4 to promote automatic feeding of nuts, ensuring that a group of nuts fall on the upper end position of the parts pushed to the upper end of the unloading column 702. At this time, the nuts and parts are merged and welding is carried out. , start the rotary welding mechanism 5 to drive the laser gun 504 to weld the contact point between the nut and the component in a circle. During the welding process, the high temperature produces harmful gases and welding slag dust. Since the unloading column 702 is connected to the cleaning mechanism 8, the harmful gases are collected, purified and discharged by the air pump to ensure that the environmental air indicators are within a safe range and the physical and mental health of the staff is guaranteed. The welding slag dust is collected in a centralized manner to reduce the subsequent cleaning of waste slag one by one and ensure the normal operation of the welding. After the welding of the nut and the component is completed, the driving mechanism 6 is started to synchronously drive the feeding component 2 and the unloading component 7. The feeding component While part 2 pushes the prepared parts to be loaded, it drives the storage linkage mechanism 3 to prepare the next group of parts, and drives the storage linkage mechanism 3 to drive the storage mechanism 4 to feed the parts. The unloading component 7 rotates and unloads the parts that have been dry-welded, and moves to a new group of unloading columns 702 to the lower right side of the workbench 101 for the next group of parts processing. Thus, the processing is repeated continuously. The staff only needs to intermittently add automobile parts and nuts to the inside of the storage linkage mechanism 3 and the storage mechanism 4, and there is no need to manually place the parts on the welding position repeatedly, thereby reducing contact with welding and improving the safety of the staff.

[0064] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
