Description

Technical Field

[0001] This invention relates to the field of automotive seat frame welding auxiliary technology, specifically to an automated positioning and welding device for automotive seat frames. Background Technology

[0002] Car seats are a crucial component of automobiles, and their comfort, safety, and durability are of paramount importance to both automakers and consumers. The car seat frame is the foundational structure of the seat, and its quality and precision directly impact the overall quality and performance of the car seat. Welding is a critical step in the manufacturing process of the car seat frame. To ensure the precision and quality of the welding, welding positioning components are used for positioning and securing.

[0003] In the welding of existing car seat frames, in order to ensure the welding of multiple areas of the car seat frame, it is necessary to rotate the car seat frame. However, the existing automated positioning welding devices for car seat frames usually rely on different electrical drive units for fixing and rotating the car seat frame. The structure is relatively complex and the cost is high. In addition, the electrical drive units are prone to damage during long-term use, which will also affect the welding efficiency. Furthermore, existing automated positioning and welding devices for automotive seat frames cannot effectively clean the residual welding slag on the surface of the automotive seat frame after welding. A separate cleaning component is required to clean the welding slag after welding, which reduces the welding efficiency of the automated positioning and welding device for automotive seat frames.

[0008] Preferably, the auxiliary component includes a limiting rod fixedly connected to the surface of the rack first, a slider slidably connected to the surface of the limiting rod, a tooth third that meshes with the gear first fixedly connected to the surface of the slider, and a spring second provided between the slider and the rack first; A connecting rod is fixedly connected to the surface of the slider, a moving rod is slidably connected to the surface of the connecting rod, a striking block is fixedly connected to the end of the moving rod, a spring pad is fixedly connected to the surface of the moving rod, and a spring three is provided between the spring pad and the connecting rod.

[0010] Preferably, the surface of the positioning frame is rotatably connected to a rotating shaft, one end of the rotating shaft extending into the connecting pipe is fixedly connected to a valve plate, the end of the moving block extending out of the positioning frame is fixedly connected to a rack, and the surface of the rotating shaft is fixedly connected to a gear three that meshes with the rack.

[0011] Preferably, a cleaning frame is fixedly installed on the inner wall of the positioning frame, and the end of the connecting pipe extends into the cleaning frame and is fixedly connected to it. Multiple air outlets are evenly opened on the surface of the cleaning frame. The surface of the positioning frame is rotatably connected to a second rotating shaft. The second rotating shaft and the first rotating shaft are connected to a belt pulley transmission mechanism.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] I. This invention, after the motor is turned on, precisely controls the rotation of the fixed frame and the fixed car seat frame through the transmission cooperation of gear one, rack one, and gear two. This enables multi-angle positioning of the car seat frame and subsequent welding operations in multiple areas of the car seat frame. This adjustment and positioning method, which uses gear rack transmission to drive the car seat frame to rotate and perform multi-angle and multi-area welding, greatly simplifies the structure and reduces the failure rate compared to the traditional method that relies on multiple electrical units to complete the rotation of the car seat frame. It is worthy of promotion and use.

[0015] II. After the automotive seat frame is welded, this invention activates a motor, causing the rack to move upwards. Through the coordinated operation of multiple structures, the automotive seat frame is first rotated 180 degrees so that the welded surface faces downwards. Then, the striking block is driven to repeatedly strike the fixed frame, causing the welded automotive seat frame to vibrate and automatically dislodge the weld slag from the surface of the welded seat frame. Simultaneously, the upward movement of the rack causes the rotating shafts one and two to rotate synchronously, closing valve plate one in the connecting pipe and opening valve plate two. This allows pressurized gas from the blower to be input into the cleaning frame and ejected through multiple air outlets. This adds air blowing cleaning while the automotive seat frame vibrates to remove weld slag, further improving the slag removal effect of the device. No additional cleaning components are needed; the same drive source controlling the rotation of the automotive seat frame and the blower on the positioning frame can complete the slag removal work after the automotive seat frame is welded, improving the welding efficiency of the device.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1, please refer to Figures 1-6 The present invention provides a technical solution: an automated positioning and welding device for an automobile seat frame, including a positioning frame 1, an mounting plate 7 fixedly connected to the surface of the positioning frame 1, a hydraulic telescopic rod 8 provided on the mounting plate 7, a connecting plate 11 fixedly connected to the output end of the hydraulic telescopic rod 8, a telescopic rod 13 fixedly connected to the surface of the connecting plate 11, a fixing frame 10 fixedly connected to the end of the telescopic rod 13, and a spring 12 provided between the fixing frame 10 and the connecting plate 11. The positioning frame 1 is equipped with positioning components for driving the fixed frame 10 to rotate to different welding angles; The positioning frame 1 is also equipped with auxiliary components, which are used to shake off the weld slag on the surface of the car seat frame after the car seat frame is flipped to the welding surface facing down on the fixed frame 10.

[0025] The positioning component includes a motor 35 mounted on the surface of the positioning frame 1. The output shaft of the motor 35 is fixedly connected to a rotating rod 19. A gear 20 is fixedly connected to the surface of the rotating rod 19. A rectangular slot 30 is opened on the surface of the positioning frame 1. A moving block 32 is slidably connected to the inner wall of the rectangular slot 30. A rack 18 is fixedly connected to the surface of the moving block 32. A plurality of teeth 21 that mesh with the gear 20 are fixedly connected to the surface of the rack 18.

[0026] The output end of the hydraulic telescopic rod 8 is fixedly connected to a gear 9, and the surface of the rack row 18 is fixedly connected to multiple teeth 17 that mesh with the gear 9.

[0027] The auxiliary components include a limiting rod 23 fixedly connected to the surface of the rack row 18, a slider slidably connected to the surface of the limiting rod 23, a tooth 24 fixedly connected to the surface of the slider and meshing with the gear 20, and a spring 22 provided between the slider and the rack row 18. A connecting rod 25 is fixedly connected to the surface of the slider. A moving rod 28 is slidably connected to the surface of the connecting rod 25. A striking block 27 is fixedly connected to the end of the moving rod 28. A spring pad 29 is fixedly connected to the surface of the moving rod 28. A spring 26 is provided between the spring pad 29 and the connecting rod 25.

[0028] The surface of the mounting plate 7 has a circular slot for the hydraulic telescopic rod 8 to extend into. The inner wall of the circular slot is fixedly connected with multiple elastic protrusions 42 arranged in a circumferential array. The fixing frame 10 is provided with anti-slip texture 16.

[0029] The surface of the mounting plate 7 has a circular slot for the hydraulic telescopic rod 8 to extend into. The inner wall of the circular slot is fixedly connected with multiple elastic protrusions 42 arranged in a circumferential array. The fixing frame 10 is provided with anti-slip texture 16.

[0030] More specifically, in this embodiment: like Figure 1As shown, the car seat frame to be welded is placed between two fixed frames 10. Then, the two hydraulic telescopic rods 8 are activated, causing the connecting plate 11 to move closer to each other, so that the two fixed frames 10 move closer to each other until both fixed frames 10 are in contact with the car seat frame. As the two hydraulic telescopic rods 8 continue to extend, the connecting plate 11 moves closer to the fixed frames 10, and the spring 12 is compressed. At this time, under the action of the elastic potential energy of the spring 12 and the thrust of the two hydraulic telescopic rods 8, the car seat frame to be welded can be fixed above the positioning frame 1. The anti-slip texture on the fixed frame 10 can further improve the static friction between the fixed frame 10 and the car seat frame after the fixed frame 10 is fixed, resulting in a better fixing effect. Then, the fixed car seat frame can be welded using external welding equipment. The specific welding operation of the car seat frame is a relatively mature existing technology, and will not be described in detail here. When it is necessary to perform multi-angle, multi-area welding operations on the fixed car seat frame, such as Figure 1 , Figure 2 and Figure 3 As shown, when motor 35 is turned on, it drives the rotating rod 19 and gear 20 to rotate. As gear 20 rotates, it drives rack 18 to move upward. As rack 18 moves upward, the meshing of multiple teeth 17 on rack 18 with gear 9 causes gear 9 to start rotating. As gear 9 rotates, it drives the fixed frame 10 and the fixed car seat frame to rotate until the car seat frame rotates to an angle suitable for welding. Then motor 35 is turned off, and subsequent multi-area welding operations of the car seat frame can be performed. This adjustment method, which uses rack and pinion transmission to drive the car seat frame to rotate for multi-angle and multi-area welding, is simpler to operate and has a lower failure rate and cost compared to the traditional method that relies on multiple electrical units to complete the rotation of the car seat frame.

[0031] It is worth noting that, such as Figure 2 and Figure 3 As shown, after the welding operation of the car seat frame is completed, the motor 35 is turned on to drive the gear 20 to rotate, so that the rack 18 moves upward, thereby causing the fixed frame 10 and the car seat frame after the welding operation to rotate 180 degrees, so that the welded surface of the car seat frame can be flipped to the downward position. At this time, the teeth 21 on the rack 18 are just engaged with the gear 20. At this time, the striking block 27 will also move to a position directly below the fixed frame 10 and close to the fixed frame 10. As the motor 35 continues to rotate, the third tooth 24 on the slider will mesh with the first gear 20. As the first gear 20 rotates, it will drive the third tooth 24 to move upward, and the second spring 22 will be compressed. When the first gear 20 and the third tooth 24 disengage, under the action of the elastic potential energy of the second spring 22, the third tooth 24 and the slider will move downward to reset. After the motor 35 is turned on, when the car seat frame between the two fixed frames 10 is rotated 180 degrees, as the motor 35 continues to rotate, under the action of the elastic potential energy of the second spring 22, the gear 20 will reciprocate to mesh with the teeth 24 on the surface of the slider, and drive the slider to reciprocate in the vertical direction. As the slider reciprocates, under the connection of the connecting rod 25, the striking block 27 will reciprocate in the vertical direction, thereby reciprocating to strike the fixed frame 10 and causing it to vibrate. When the vibration is transmitted to the car seat frame, since the car seat frame has been rotated 180 degrees to the position with the welding surface facing down, the welding slag after the car seat frame is welded can be dislodged under the action of the vibration force. No additional cleaning parts are needed. The cleaning work after the car seat frame is welded can be completed by the same drive source motor 35 that controls the rotation of the car seat frame, which improves the welding efficiency of the device.

[0032] Example 2, based on the above examples: Furthermore, a fan 4 is provided on the surface of the positioning frame 1, an air outlet pipe 5 is fixedly connected to the surface of the fan 4, a connecting pipe 6 is fixedly connected to the surface of the positioning frame 1, the end of the air outlet pipe 5 is fixedly connected to the connecting pipe 6, a connecting pipe 14 is fixedly connected to the surface of the connecting pipe 6, a mounting frame 40 is fixedly installed on the surface of the positioning frame 1, a cleaning nozzle 15 is placed on the mounting frame 40, an air inlet pipe 41 is fixedly connected to the surface of the cleaning nozzle 15, and a flexible hose is fixedly connected between the air inlet pipe 41 and the connecting pipe 14.

[0033] The surface of the positioning frame 1 is rotatably connected to a rotating shaft 31. One end of the rotating shaft 31, which extends into the connecting pipe 6, is fixedly connected to a valve plate 38. The end of the moving block 32, which extends out of the positioning frame 1, is fixedly connected to a rack 33. The surface of the rotating shaft 31 is fixedly connected to a gear 37 that meshes with the rack 33.

[0034] A cleaning frame 2 is fixedly installed on the inner wall of the positioning frame 1. The end of the connecting pipe 6 extends into the cleaning frame 2 and is fixedly connected to it. Multiple air outlets 3 are evenly opened on the surface of the cleaning frame 2. The surface of the positioning frame 1 is rotatably connected to a rotating shaft 34. A belt pulley transmission mechanism 36 is provided between the rotating shaft 34 and the rotating shaft 31. A valve plate 39 is fixedly connected to the end of the rotating shaft 34 that extends into the connecting pipe 6.

[0035] More specifically, in this embodiment: like Figure 3 , Figure 4 and Figure 5 As shown, in this state, valve plate 38 in connecting pipe 1 is open, while valve plate 39 is closed. When the blower 4 is turned on, the outside air is pressurized and input into connecting pipe 1 6 through the air outlet pipe 5. Since valve plate 39 is closed, the pressurized gas in connecting pipe 1 6 will enter the cleaning nozzle 15 through connecting pipe 2 14 and the hose. At this time, the operator can hold the cleaning nozzle 15 and blow air to clean the unwelded parts of the car seat frame. This will blow away the dust and impurities at the welding position before the welding operation of the car seat frame, so as to avoid the dust and impurities affecting the subsequent welding operation and improve the welding accuracy of the device. It is worth noting that when the welding operation of the car seat frame is completed, by turning on the motor 35, the rack row 18 is moved upward, causing the car seat frame to rotate 180 degrees to the position with the welding surface facing down. As the rack row 18 moves upward, under the connecting action of the moving block 32, the rack row 2 33 is also moved upward, causing the rack row 2 33 to mesh with the gear 37, causing the gear 37 to rotate 90 degrees. As the gear 37 rotates, the rotating shaft 31 rotates 90 degrees. Under the transmission action of the belt pulley drive mechanism 36, the rotating shaft 2 34 rotates synchronously 90 degrees, thereby allowing the valve plate 38 at the end of the rotating shaft 31 and... The valve plate 39 at the end of the rotating shaft 34 rotates 90 degrees synchronously, so that the valve plate 38 closes and the valve plate 39 opens. In this state, the blower 4 is turned on again, so that the pressurized gas is input into the cleaning frame 2 through the connecting pipe 6, and finally discharged from the multiple air outlets 3 on the surface of the cleaning frame 2. Since the car seat frame has been flipped to the position with the welded surface facing down in this state, and the striking block 27 is reciprocatingly striking the fixed frame 10, the welding slag on the welded surface of the car seat frame is shaken off by the vibration force. The vibration force combined with the air blowing from the multiple air outlets 3 can better shake off the welding slag and impurities attached to the surface of the car seat frame, and the cleaning effect is better.

[0036] It is worth noting that after the car seat frame is rotated 180 degrees, since the teeth 21 on the rack 18 are engaged with the gear 20, before the motor 35 rotates in the opposite direction and drives the car seat frame to rotate and reset, the car seat frame will be in a stable state under the action of the elastic potential energy of the multiple elastic protrusions 42 and will not rotate easily.

[0037] In summary, after the car seat frame is welded, the motor 35 is turned on, causing the rack 18 to move upward, first rotating the car seat frame 180 degrees so that the welded surface is facing down. Then, through the linkage of multiple structures, the slider is driven to move the striking block 27 back and forth, repeatedly striking the fixed frame 10, causing the welded car seat frame to vibrate, automatically dislodging the weld slag from the surface of the car seat frame with the welded surface facing down. At the same time, the upward movement of the rack 18 drives the rack 23 to move upward and mesh with the gear 37, driving the rotating shaft 31 and the rotating shaft 32 to move upward. 4. The synchronous rotation closes valve plate 1 in connecting pipe 6 and opens valve plate 2 39, allowing pressurized gas from blower 4 to be input into cleaning frame 2 and sprayed out through multiple air outlets 3. This allows for simultaneous vibration cleaning of welding slag on the car seat frame and air blowing cleaning, further improving the slag removal effect of the device. No additional cleaning components are needed. The cleaning work after the car seat frame welding is completed by controlling the same drive source motor 35 that controls the rotation of the car seat frame and the blower 4 on the positioning frame 1, which improves the welding efficiency of the device and is worthy of promotion and use.
