Technical Field

[0001] This application relates to the technical field of welding automotive interior parts, and in particular to a beam welding device. Background Technology

[0002] Welding of the beams in automotive interior components is a critical step in the automobile manufacturing process, and its welding quality directly affects the safety and comfort of the vehicle. With the development of the automotive industry, the requirements for welding efficiency and product quality are becoming increasingly stringent. Currently, automotive interior component welding mostly uses traditional welding equipment, which is greatly affected by external airflow in an open welding environment. This makes it difficult to control temperature fluctuations at the weld joint, resulting in unstable welding quality, a high incidence of welding defects, and an inability to meet the high standards required by modern automobile manufacturing. Summary of the Invention

[0003] In order to effectively control the temperature fluctuation at the weld joint during the welding process and improve the welding quality, this application provides a beam welding equipment.

[0004] The technical solution adopted in this application for a beam welding device is as follows: A beam welding device includes an outer frame, a windbreak door, a welding mechanism, and a fixing component. The outer frame has a welding cavity, and a connecting opening is provided on one side wall of the welding cavity, which is connected to the outside. The windbreak door is connected to the outer frame and covers the connecting opening. The fixing component is embedded in the welding cavity and is used to place and fix the product. The welding mechanism is embedded in the welding cavity and is used to weld the product above the fixing component.

[0005] By adopting the above technical solution, the welding cavity of the outer frame can provide a relatively stable welding space, the windproof door covering the connecting opening can reduce the impact of external airflow on welding, the fixing component can place and fix the product to ensure the stability of the product during the welding process, and the welding mechanism can weld the fixed product, thereby realizing the effective welding of the middle beam product, effectively controlling the temperature fluctuation at the welding point during the welding process, and improving the welding quality.

[0006] Preferably, it further includes a closed drive cylinder, a chamber door, and a feeding mechanism. The outer frame is provided with a temporary storage cavity, and the wall of the temporary storage cavity is provided with a feeding port, which is connected to the outside. The chamber door is connected to the outer frame and covers the feeding port. The connecting port connects the temporary storage cavity and the welding cavity. The windproof door is slidably embedded in the welding cavity, and the sliding direction of the windproof door is vertical. The closed drive cylinder is connected to the outer frame and is used to drive the windproof door to slide. The feeding mechanism is embedded in the temporary storage cavity and is used to transport the fixed components and products into the welding cavity.

[0007] By adopting the above technical solution, the product can be clamped onto the fixing component in the temporary storage cavity, then the hopper door can be closed and the windproof door can be opened. The fixing component and the product can be transported to the welding cavity through the feeding mechanism. This reduces the possibility of heat exchange between the air in the welding cavity and the outside air through the unloading groove during the feeding operation, effectively controls the temperature fluctuation at the welding point, and improves the welding quality.

[0008] Preferably, the assembly also includes a detection mechanism. The welding mechanism includes a welding drive cylinder, a connecting seat, and a spot welding head. The connecting seat is slidably embedded in the welding cavity, and the sliding direction of the connecting seat is vertical. The welding drive cylinder is connected to the outer frame and is used to drive the connecting seat to slide. One end of the spot welding head is connected to the connecting seat, and the other end of the spot welding head is used to abut against the product above the fixed assembly. The detection mechanism includes a first sensor, a second sensor, and a controller. The controller is connected to the outer frame and is used to control the operation of the closed drive cylinder. The first sensor is connected to the wall of the welding cavity and is used to detect the position of the connecting seat and send a signal to the controller. The second sensor is connected to the outer frame and is used to detect the position of the door and send a signal to the controller.

[0009] By adopting the above technical solution, the position of the connector is detected by the first sensor. When the first sensor detects the connector, it sends a signal to the controller. The controller determines that the welding mechanism has completed welding and is far away from the product. The position of the compartment door is detected by the second sensor. When the second sensor detects the compartment door, it sends a signal to the controller. The controller determines that the compartment door is closed and the temporary storage cavity is not connected to the outside world. Only then can the connection port be opened, thereby improving the automation level and reliability of the equipment.

[0010] Preferably, the assembly further includes a rotating plate, a feeding mechanism, and a transfer mechanism. The feeding mechanism includes a feeding plate and a feeding drive assembly. The bottom of the welding cavity is provided with a feeding groove, which is located on the side of the welding mechanism away from the connecting opening along the conveying direction of the feeding mechanism. The rotating plate is rotatably connected to the outer frame to cover the opening of the feeding groove. The rotation axis of the rotating plate is horizontal. The feeding plate is slidably embedded in the feeding groove, and the sliding direction of the feeding plate is vertical. The feeding plate is used for placing fixed components. The feeding drive assembly is connected to the outer frame and is used to drive the feeding plate to slide. The transfer mechanism is used to transport the fixed components above the feeding mechanism to the bottom of the welding mechanism or to transport the fixed components below the welding mechanism to the top of the feeding plate.

[0011] By adopting the above technical solution, the transfer mechanism transports the finished product and fixed components to the unloading plate, and then transports the product to be finished and fixed components to the bottom of the welding mechanism. The unloading drive component drives the unloading plate to descend, which in turn drives the fixed components and products to descend. At this time, the rotating plate rotates to separate the unloading groove wall, reducing the possibility of heat exchange between the air in the welding cavity and the outside air through the unloading groove, effectively controlling the temperature fluctuation at the welding point and improving the welding quality.

[0012] Preferably, the transfer mechanism includes a first insert, a first sliding seat, a first drive cylinder, and a first horizontal drive assembly. The first sliding seat is slidably embedded in the welding cavity, and the sliding direction of the first sliding seat is parallel to the conveying direction of the feeding mechanism. The first horizontal drive assembly is connected to the outer frame and is used to drive the first sliding seat to slide. The fixing assembly is provided with a groove. The first insert is slidably connected to the first sliding seat and is used to embed in the groove. The first drive cylinder is connected to the first sliding seat and is used to drive the first insert to slide in the horizontal direction.

[0013] By adopting the above technical solution, the first insert is driven by the first drive cylinder to embed into the slot, thereby achieving relative fixation between the first insert and the fixed component. This facilitates the sliding of the first sliding seat, which in turn drives the first insert to slide and the fixed component to slide, thus realizing the loading and unloading operations and improving the automation level of the equipment.

[0014] Preferably, the bottom of the welding cavity is provided with a first positioning groove, which is directly opposite to the welding mechanism. The first positioning groove is used for embedding the fixing component. The groove wall of the first positioning groove is in contact with the side wall of the fixing component. The transfer mechanism further includes a first vertical driving component, which is connected to a first sliding seat. The first vertical driving component is used to drive the first insert to slide in the vertical direction.

[0015] By adopting the above technical solution, a first positioning groove is provided at the bottom of the welding cavity. The wall of the first positioning groove fits against the side wall of the fixed component, reducing the possibility of relative movement of the fixed component in the horizontal direction during the welding process, improving the reliability of the equipment, and improving the welding quality.

[0016] Preferably, the transfer mechanism further includes a connecting strip, one end of the first insert is connected to the connecting strip, and there are a plurality of first inserts, which are divided into two groups. The two groups of first inserts are distributed at intervals along the sliding direction of the first sliding seat, and a plurality of first inserts in the same group are distributed at intervals along the sliding direction of the first sliding seat.

[0017] By adopting the above technical solution, the connecting strip is connected to two sets of first inserts, which can perform loading and unloading operations simultaneously, thereby improving the efficiency of loading and unloading and increasing the production efficiency of the equipment.

[0018] Preferably, the device further includes a first reset member, a rack, and a gear. The gear is connected to the rotating plate, and the gear axis coincides with the rotation axis of the rotating plate. A first connecting groove is provided on the wall of the feeding groove. The rack is slidably embedded in the first connecting groove. The sliding direction of the rack is horizontal. The rack meshes with the gear. One end of the rack extends into the feeding groove. The end of the rack extending into the feeding groove is provided with a first chamfer. The first chamfer is located on the side of the rack near the welding cavity. The first chamfer is used to abut against the lower end of the feeding plate. The first reset member is connected between the rack and the outer frame. The first reset member makes the end of the rack near the feeding groove tend to extend out of the first connecting groove. When the end of the rack near the feeding groove is embedded in the first connecting groove, the rotating plate closes the opening of the feeding groove.

[0019] By adopting the above technical solution, when the feeding plate moves down, the feeding plate abuts against the first chamfer, pushing the rack to slide. The rack meshes with the gear, driving the rotating plate to rotate to achieve the sealing of the feeding trough opening, thus improving the automation level of the equipment.

[0020] Preferably, it also includes a conveying mechanism. The outer frame is provided with a connecting channel. One end of the connecting channel is connected to the feeding trough, and the other end of the connecting channel passes through the outer frame. The end of the connecting channel away from the feeding trough is located below the temporary storage cavity. The conveying mechanism is embedded in the connecting channel. The conveying mechanism is used to convey the fixed components above the feeding plate to the side of the connecting channel near the temporary storage cavity.

[0021] By adopting the above technical solution, the finished products and fixing components above the feeding plate are transported to the side near the temporary storage cavity by the conveying mechanism. This makes it easier for workers to remove the finished products and put the fixing components back into the temporary storage cavity for the next product clamping, thereby improving the utilization rate of the fixing components and reducing production costs.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The welding cavity of the outer frame can provide a relatively stable welding space. The windproof door covering the connection can reduce the impact of external airflow on welding. The fixing component can place and fix the product to ensure the stability of the product during the welding process. The welding mechanism can weld the fixed product, thereby realizing the effective welding of the middle beam product, effectively controlling the temperature fluctuation at the welding point during the welding process, and improving the welding quality. 2. The product can be clamped onto the fixing component in the temporary storage chamber, then the chamber door is closed and the windproof door is opened. The fixing component and the product are then transported to the welding chamber through the feeding mechanism. This reduces the possibility of heat exchange between the air in the welding chamber and the outside air through the unloading groove during the feeding operation, effectively controls the temperature fluctuation at the welding point, and improves the welding quality. 3. The transfer mechanism transports the finished product and fixed components to the unloading plate, and then transports the product to be finished and fixed components to the area below the welding mechanism. The unloading drive component drives the unloading plate to descend, which in turn drives the fixed components and products to descend. At this time, the rotating plate rotates to separate the unloading groove wall, reducing the possibility of heat exchange between the air in the welding cavity and the outside air through the unloading groove, effectively controlling the temperature fluctuation at the welding point and improving the welding quality.

The output shaft of the feeding drive motor 433 is coaxially fixedly connected to the end of the feeding screw 432 away from the welding cavity 121. The lower end of the feeding plate 41 near the welding cavity 121 is provided with a second groove 413. The pulley rotates and is embedded in the second groove 413. The rotation axis of the roller 42 is parallel to the width direction of the outer frame 12. The outer wall of the roller 42 is used to fit against the cavity wall of the welding cavity 121.

[0041] Reference Figure 1 and Figure 6A beam welding device further includes a transfer mechanism 7, which is used to transport the fixed component 3 above the loading plate 41 to the first positioning groove 126 or to transport the fixed component 3 in the first positioning groove 126 to the unloading plate 61. The transfer mechanism 7 includes a first insert 71, a connecting strip 76, a first sliding seat 72, a first lifting seat 77, a first drive cylinder 73, a first horizontal drive component 74, and a first vertical drive component 75. The first sliding seat 72 is slidably embedded in the welding cavity 121. The sliding direction of the first sliding seat 72 is parallel to the length direction of the outer frame 12. There are two first sliding seats 72, which are symmetrically distributed along the width direction of the outer frame 12. The number of connecting strips 76, first lifting seats 77, first drive cylinder 73, first horizontal drive component 74, and first vertical drive component 75 is the same as the number of first sliding seats 72 and corresponds one-to-one. The first horizontal drive component 74 is embedded in the welding cavity 121 and is used to drive the first sliding seat 72 to slide. The first lifting seat 77 is slidably connected to the first sliding seat 72, and the sliding direction of the first lifting seat 77 is vertical. The first vertical drive assembly 75 is connected to the first sliding seat 72 and is used to drive the first lifting seat 77 to slide in the vertical direction. The connecting strip 76 is slidably connected to the first lifting seat 77, and the sliding direction of the connecting strip 76 is parallel to the width direction of the outer frame 12. One end of the first insert 71 is fixedly connected to the side of the connecting strip 76 near the other connecting strip 76, and the other end of the first insert 71 is used to embed into the groove 31.

[0042] In this embodiment, one connecting strip 76 corresponds to four first inserts 71. The four first inserts 71 are divided into two groups, and the two groups of first inserts 71 are distributed at intervals along the length of the outer frame 12. When the first insert 71 on the side closer to the temporary storage cavity 123 is aligned with the groove 31 of the fixing component 3 above the loading plate 41, the other group of first inserts 71 is aligned with the groove 31 of the fixing component 3 in the first positioning groove 126. When the first insert 71 on the side closer to the temporary storage cavity 123 is aligned with the groove 31 of the fixing component 3 in the first positioning groove 126, the other group of first inserts 71 is aligned with the groove 31 of the fixing component 3 above the unloading plate 61.

[0043] The implementation principle of a beam welding device according to an embodiment of this application is as follows: The chamber door 14 is opened, the windbreak door 11 is closed, the fixing component 3 is embedded into the third positioning groove 411, and the product is fixedly connected to the upper end of the fixing component 3. After clamping, the chamber door 14 is closed. When the chamber door 14 approaches the first receiving groove 129, an attraction is generated between the magnetic strip 19 and the outer frame 12, causing the chamber door 14 to embed into the first receiving groove 129. The second sensor 52 detects that the chamber door 14 is embedded in the first receiving groove 129 and sends a signal to the controller. When the welding drive cylinder 21 drives the connecting seat 22 to move upward, causing the spot welding head 23 to move away from the product, the first sensor 51 detects the connecting seat 22 and sends a signal to the controller. The controller controls the piston rod of the closed drive cylinder 13 to retract, causing the windbreak door 11 to move upward, so that the temporary storage chamber 123 communicates with the welding chamber 121.

[0044] The feeding drive motor 433 operates, driving the feeding screw 432 to rotate. The feeding screw 432 is threadedly connected to the second guide block 412, causing the feeding plate 41 to slide. This causes the fixed component 3 in the third positioning groove 411 and the product to enter the welding cavity 121 through the connecting port 122. The first horizontal drive component 74 operates, driving the first sliding seat 72 to slide, and driving the first insert 71 to slide. This causes the two sets of first inserts 71 on the same connecting bar 76 to simultaneously align with the groove 31 of the fixed component 3 above the feeding plate 41 and the groove 31 of the fixed component 3 in the first positioning groove 126. The piston rod of the first drive cylinder 73 extends, causing the connecting bar 76 to slide closer to the fixed component 3, so that the first insert 71 extends into the groove 31. The first vertical drive component 75 operates, driving the first lifting seat 77 to move upward, causing the two fixed components 3 to disengage from the third positioning groove 411 and the first positioning groove 126. The first horizontal drive component 74 operates, causing the first sliding seat 72 to slide, which in turn causes the two fixed components 3 to slide, so that the two fixed components 3 are respectively aligned with the first positioning groove 126 and the second positioning groove 611. The first vertical drive component 75 operates, causing the first lifting seat 77 to move down, causing the fixed components 3 to be embedded in the first positioning groove 126 and the second positioning groove 611. The piston rod of the first drive cylinder 73 retracts, causing the connecting strip 76 to slide away from the fixed components 3, so that the first insert 71 disengages from the groove 31.

[0045] The feeding drive motor 622 operates, driving the feeding screw 621 to rotate. The feeding screw 621 is threadedly connected to the first guide block 612, driving the feeding plate 61 to move downward, driving the fixing component 3 to move downward. The lower end of the feeding plate 61 abuts against the first chamfer 171, pushing the rack 17 to slide into the first connecting groove 127. The rack 17 meshes with the gear 18, driving the gear 18 to rotate, driving the rotating plate 15 to rotate and embed into the third receiving groove 1217. The feeding plate 61 continues to move downward, and the abutting plate 613 abuts against the rack 17. The second horizontal drive assembly 84 operates, causing the second sliding seat 82 to slide, which in turn causes the second insert 81 to slide, aligning the second insert 81 with the groove 31 of the fixed assembly 3 above the feed plate 61. The piston rod of the second drive cylinder 83 extends, causing the second insert 81 to slide closer to the fixed assembly 3, so that the second insert 81 extends into the groove 31. The second vertical drive assembly 85 operates, causing the second lifting seat 87 to move upward, causing the fixed assembly 3 to disengage from the second positioning groove 611. The second horizontal drive assembly 84 operates, causing the second sliding seat 82 to slide, which in turn causes the fixed assembly 3 to slide, so that the fixed assembly 3 is positioned above the conveyor belt 86. The second vertical drive assembly 85 operates, causing the second lifting seat 87 to move downward, causing the lower end of the fixed assembly 3 to abut against the conveyor belt 86. The piston rod of the second drive cylinder 83 retracts, causing the second insert 81 to disengage from the groove 31. The conveyor belt 86 transports the fixed assembly 3 to the side of the connecting channel 128 near the temporary storage chamber 123.

[0046] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
