[0034] In one embodiment, see Figures 3 to 5 As shown, a seat support welding device provided by the present invention comprises a workbench 1, a welding module 2, a pipe clamping module 3, and a side panel clamping module 4 fixedly connected to the workbench 1. The welding module 2 adopts a multi-degree-of-freedom welding robot to achieve multi-angle welding; the pipe clamping module 3 is used to clamp the headrest pipe part of the seat support; and the side panel clamping module 4 is used to clamp the two side panels of the seat support.

[0035] The pipe clamping module 3 includes two groups of first pipe clamping units 5 and several groups of second pipe clamping units 6. The first pipe clamping unit 5 has a first clamping slot 501 that can be moved and opened and closed. The two groups of first clamping slots 501 are respectively used to clamp the ends of the seat support headrest tube. The second pipe clamping unit 6 has a second clamping slot 601 that can be opened and closed. The second clamping slot 601 is used to clamp the body of the seat support headrest tube. Among them, the two first clamping slots 501 respectively clamp the two ends of the seat support headrest tube and can move according to the setting to avoid interfering with the assembly of the seat support headrest tube and the seat support side plate.

[0036] The side panel clamping module 4 includes a horizontal movable table 41 that can move toward or away from the pipe clamping module 3, and two groups of symmetrically arranged side panel clamping units 7 are fixed on the horizontal movable table 41. The side panel clamping unit 7 includes a first side panel clamping groove 701 and a second side panel clamping groove 702 that can be opened and closed. The first side panel clamping groove 701 is used to clamp the end of the seat bracket side panel toward the headrest tube, and the second side panel clamping groove 702 is used to clamp the end of the seat bracket side panel toward the headrest tube. Among them, the side panel clamping module 4 also includes a horizontal motor, a horizontal lead screw and a horizontal guide rail. The horizontal lead screw is fixed to the upper end of the workbench 1 by a bearing connection, the horizontal motor is fixed to the upper end of the workbench 1 by a bolt connection, the output shaft of the horizontal motor is fixedly connected to the horizontal lead screw, the horizontal guide rail is fixed to the upper end of the workbench 1 along the length direction of the workbench 1 by a bolt connection, a horizontal sliding block is fixed to the lower end of the horizontal moving table 41, the horizontal sliding block is slidably mounted on the outer wall of the horizontal guide rail, and a driving nut is fixed to the lower end of the horizontal moving table 41, and the driving nut is mounted on the outer wall of the horizontal lead screw; when the horizontal moving table 41 moves, the horizontal motor works, the output shaft of the horizontal motor drives the horizontal lead screw to rotate, the horizontal lead screw drives the driving nut to move, and the driving nut drives the horizontal moving table 41 to move toward or away from the pipe clamping module 3.

[0037] The horizontal moving platform 41 can move toward the pipe clamping module 3 so that the end of the seat support headrest tube is plugged into the seat support side plate. The seat support side plate has a C-shaped slot, and the seat support headrest tube is plugged into the C-shaped slot and fixed by welding.

[0038] Working process:

[0039] S1: Place the seat support headrest tube in the first clamping groove 501 and the second clamping groove 601, the first tube clamping unit 5 fixes the end position of the seat support headrest tube, and the second tube clamping unit 6 fixes the tube body of the seat support headrest tube;

[0040] S2: Put the seat frame side panel into the first side panel clamping groove 701 and the second side panel clamping groove 702, and the side panel clamping unit 7 fixes the seat frame side panel.

[0041] S3: The horizontal moving platform 41 moves toward the pipe clamping module 3, driving the seat bracket side plate to move toward the pipe clamping module 3, so that the end position of the seat bracket headrest tube is inserted into the corresponding seat bracket side plate until it reaches the set position;

[0042] S4: the first pipe clamping unit 5 is separated from the headrest pipe of the seat support, and the horizontal moving platform 41 continues to move toward the pipe clamping module 3 until the headrest pipe of the seat support is inserted to a set depth of the side plate of the seat support;

[0043] S5: The welding module 2 works to weld the seat bracket until the welding is completed.

[0044] In summary, the present invention realizes the automatic assembly of the headrest tube and the side panel of the seat bracket through the cooperation of the first tube clamping unit 5, the second tube clamping unit 6, the side panel clamping unit 7 and the welding module 2, thereby ensuring the assembly accuracy and welding accuracy of the car seat bracket, avoiding cold welding caused by inadequate manual assembly, and improving the welding efficiency of the car seat bracket.

[0045] In an alternative example, see Figures 3 to 6 As shown, the first pipe clamping unit 5 includes a first pipe base 51 and a first pipe rotating and telescopic cylinder 52 fixedly connected to the workbench 1 by bolt connection. The upper end of the first pipe base 51 is provided with a first pipe groove 511. The first pipe rotating and telescopic cylinder 52 has a rotating and telescopic part. The lower end of the rotating and telescopic part is fixed with a first pipe clamping block 53 by bolt connection. The lower end of the first pipe clamping block 53 is provided with a second pipe groove 531. The first pipe groove 511 and the second pipe groove 531 are combined to form a first clamping through groove 501. The first pipe rotating and telescopic cylinder 52 can be an angle hydraulic cylinder. The rotating and telescopic part can be rotated to a designed angle in the downward pressing stroke, and then pressed down vertically, so that the first pipe clamping block 53 presses the headrest tube of the seat bracket downward, which can avoid interfering with the movement of the seat bracket.

[0046] Specifically, when the first tube rotating and telescopic cylinder 52 is working, the rotating and telescopic part of the first tube rotating and telescopic cylinder 52 drives the first tube clamping block 53 to press the headrest tube of the seat bracket downward, thereby realizing the rapid clamping of the headrest tube of the seat bracket. In addition, the first tube clamping block 53 can avoid the removal path of the seat bracket through the operation of the first tube rotating and telescopic cylinder 52, thereby avoiding interfering with the movement of the seat bracket.

[0047] In an alternative example, see Figures 3 to 8As shown, the second pipe clamping unit 6 includes a second pipe clamping base 61 fixedly connected to the workbench 1 by bolt connection, a clamping slide frame 62 is provided on the second pipe clamping base 61 by sliding connection along the width direction of the workbench 1, a second pipe telescopic cylinder 63 is fixed to the second pipe clamping base 61 by bolt connection, the telescopic end of the second pipe telescopic cylinder 63 is fixedly connected to the clamping slide frame 62 by bolt connection, a second pipe clamping block 64 is fixed to the clamping slide frame 62 by bolt connection, and a third pipe is provided on the second pipe clamping block 64. The second pipe clamping block 64 is provided with a clamping ring 65 which matches the third pipe groove 641 by rotation. The third pipe groove 641 and the clamping ring 65 are combined to form a second clamping through groove 601. A plurality of clamping teeth 651 are provided on the outer wall of the clamping ring 65. A clamping motor 66 is fixed to the clamping slide frame 62 by bolt connection. A driving gear 67 is fixed to the output shaft of the clamping motor 66 by key connection. A driven gear 68 is installed on the clamping slide frame 62 by a rotating shaft. The driven gear 68 is meshed with the clamping teeth 651 and the driving gear 67. Among them, the clamping sliding frame 62 has two sliding guide pillars, and the second pipe clamping base 61 is provided with a guide hole matching the sliding guide pillar; the third pipe groove 641 is arranged in an arc shape, and the side wall of the second pipe clamping block 64 is provided with a side slide groove, and a side slider is arranged on the side of the clamping ring 65 facing the second pipe clamping block 64, and the side slider is slidably inserted in the side slide groove; the clamping motor 66 has a self-locking function.

[0048] Specifically, when the clamping motor 66 works in the forward direction, the output shaft of the clamping motor 66 drives the driving gear 67 to rotate, the driving gear 67 drives the driven gear 68 to rotate, and the driven gear 68 drives the clamping ring 65 to rotate until the clamping ring 65 rotates to the set position and combines with the third pipe groove 641 to clamp the end of the seat bracket headrest tube, thereby realizing the rapid clamping of the seat bracket headrest tube. At the same time, when the seat bracket headrest tube is inserted and set to the set position, when the clamping motor 66 works in the reverse direction, the clamping ring 65 rotates to the initial position. At this time, the second pipe telescopic cylinder 63 works, and the telescopic end of the second pipe telescopic cylinder 63 drives the clamping sliding frame 62 to move in the direction away from the seat bracket headrest tube until it moves to the set position, which can avoid interfering with the subsequent movement of the seat bracket side panel and the removal path of the seat bracket.

[0049] In an alternative example, see Figures 3 to 11As shown, during the clamping and fixing process of the C-shaped slot, the C-shaped slot of the seat bracket side plate is easily deformed, causing the aperture of the C-shaped slot to become smaller, and the seat bracket headrest tube is not easy to insert into the deformed C-shaped slot. In order to facilitate the insertion of the seat bracket headrest tube into the seat bracket side plate, a hole expansion component 9 is fixed in the first side plate clamping groove 701. The hole expansion component 9 has a movable magnetic suction part 901 that can move in a direction perpendicular to the central axis of the first side plate clamping groove 701. The movable magnetic suction part 901 can fit with the outer wall of the seat bracket side plate where the seat bracket headrest tube is connected. Among them, the movable magnetic suction part 901 can absorb the seat bracket side plate so that the C-shaped slot can open a certain angle.

[0050] Specifically, this example causes a certain amount of deformation of the seat bracket side panel through the magnetic attraction and movement of the movable magnetic attraction part 901, so that the C-shaped slot can open a certain angle, which is convenient for the rapid insertion of the seat bracket headrest tube and improves the rapid assembly of the seat bracket headrest tube and the seat bracket side panel.

[0051] In an alternative example, see Figures 3 to 11 As shown, the side plate clamping module 4 also includes a vertical moving module 8 fixedly connected to the horizontal moving platform 41 by bolt connection, and the vertical moving module 8 has a vertical moving end 81 capable of vertical movement, and a vertical moving bracket 82 is fixed on the vertical moving end 81. Among them, the vertical moving module 8 adopts a linear moving module, and the linear moving module has a linear motor, and the linear motor is used to control the vertical movement of the vertical moving end 81.

[0052] The side panel clamping unit 7 includes a first side panel clamping assembly 71, and the first side panel clamping assembly 71 includes a first side panel clamping base 711 and a first side panel movable base 712. The first side panel clamping base 711 is fixedly connected to the horizontal moving platform 41 by means of bolt connection. A first side panel lower groove 7111 is provided at the upper end of the first side panel clamping base 711. The first side panel movable base 712 is connected to the vertical moving bracket 82 by means of a rotating shaft. A driving telescopic rod 83 is installed on the vertical moving bracket 82 by means of a rotating shaft. The telescopic end of the driving telescopic rod 83 is connected to the first side panel movable base 712 by means of a rotating shaft. A first side panel upper groove 7121 is provided at the lower end of the first side panel movable base 712. The first side panel lower groove 7111 and the first side panel upper groove 7121 are combined to form the first side panel clamping groove 701. The driving telescopic rod 83 and the rotating shaft center line of the first side plate movable base 712 are arranged along the length direction of the workbench 1 .

[0053] The first side panel clamping base 711 includes a base support body 1 713 and two base support bodies 2 714. The base support body 1 713 is fixedly connected to the horizontal moving platform 41 by bolt connection. The base support body 2 714 is fixed to the upper end of the base support body 1 713 by bolt connection. The lower slot 7111 of the first side panel is opened at the upper end of the base support body 2 714. The first side panel movable base 712 includes a movable bracket 7122 and two movable support bodies 7123. The movable bracket 7122 is connected to the vertical moving bracket 82 by a rotating shaft. The telescopic end of the driving telescopic rod 83 is connected to the movable bracket 7122 by a rotating shaft. The movable support body 7123 is fixed to the lower end of the movable bracket 7122 by bolt connection. The upper slot 7121 of the first side panel is opened at the lower end of the movable support body 7123.

[0054] Specifically, in this example, the cooperation between the upper groove 7121 of the first side panel and the lower groove 7111 of the first side panel is used to achieve rapid fixation of the side panel of the seat bracket, thereby improving the positioning and welding efficiency of the side panel of the seat bracket. At the same time, through the cooperation between the vertical moving module 8, the driving telescopic rod 83 and the first side panel clamping assembly 71, the movable base 712 of the first side panel can move enough space to avoid interfering with the removal of the seat bracket.

[0055] In an alternative example, see Figures 3 to 11 As shown, a guide 715 is further provided at one end of the first side plate clamping groove 701 close to the pipe clamping module 3 , and a penetrating guide channel is provided in the guide 715 , and the guide channel is connected to the first side plate clamping groove 701 .

[0056] Specifically, the guide 715 provided in this example enables the headrest tube of the seat bracket to be smoothly inserted into the C-shaped groove of the side panel of the seat bracket, thereby facilitating the rapid assembly of the seat bracket.

[0057] In an alternative example, see Figures 3 to 11 As shown, the guide channel is trumpet-shaped, and the guide 715 includes an upper cover body 7151 and a lower cover body 7152 . The upper cover body 7151 is fixedly connected to the first side plate movable base 712 , and the lower cover body 7152 is fixedly connected to the first side plate clamping base 711 .

[0058] Specifically, the guide 715 of this example is split into two parts: an upper cover 7151 and a lower cover 7152, which can avoid interfering with the removal of the seat bracket.

[0059] In an alternative example, see Figures 3 to 11As shown, the hole expansion assembly 9 includes a fan-shaped fixed magnetic conductive sheet 91 and a fixed electromagnet 92 fixed on the second base support body 714, the fan-shaped fixed magnetic conductive sheet 91 is fixed in the lower slot 7111 of the first side plate, the fixed electromagnet 92 is fixedly connected to the first side plate clamping base 711, and the electromagnetic part of the fixed electromagnet 92 is fixedly connected to the fan-shaped fixed magnetic conductive sheet 91. Among them, the second base support body 714 is made of a magnetic shielding material, such as plastic, etc.; the fan-shaped fixed magnetic conductive sheet 91 is made of a magnetic conductive material, such as an iron alloy, etc.; the fixed electromagnet 92 can generate magnetic force after being energized, and does not generate magnetic force when not energized.

[0060] The movable magnetic attraction part 901 includes a fan-shaped movable magnetic conductive sheet 93, a movable electromagnet 94 and an electromagnetic telescopic rod 95 fixed on a base support body 713. The fan-shaped movable magnetic conductive sheet 93 is arranged in a slot 7121 in the upper part of the first side plate. A sliding column is arranged on the outer wall of the fan-shaped movable magnetic conductive sheet 93. A sliding hole arranged in a direction perpendicular to the central axis of the end of the headrest tube of the seat bracket is opened in the slot 7121 in the upper part of the first side plate. The sliding column is slidably inserted in the sliding hole. The telescopic end of the electromagnetic telescopic rod 95 is fixedly connected to the movable electromagnet 94, and the electromagnetic part of the movable electromagnet 94 is fixedly connected to the fan-shaped movable magnetic conductive sheet 93.

The third support seat 10 is provided with a positioning groove for positioning the seat frame back plate, the seat frame back plate is placed in the positioning groove, and the welding module 2 can weld the seat frame back plate.

[0065] Specifically, in this example, by adding the third support seat 10, the backrest plate of the seat bracket can be assembled and connected during welding of the seat bracket, thereby reducing the process steps of the seat bracket and further improving the welding and production efficiency of the seat bracket.

[0066] In general, the present invention realizes the automatic assembly of the headrest tube and the side panel of the seat bracket through the cooperation of the first tube clamping unit 5, the second tube clamping unit 6, the side panel clamping unit 7 and the welding module 2, thereby ensuring the assembly accuracy and welding accuracy of the car seat bracket, avoiding cold welding caused by inadequate manual assembly, and improving the welding efficiency of the car seat bracket. In addition, through the magnetic attraction and movement of the movable magnetic attraction part 901, the side panel of the seat bracket produces a certain amount of deformation, so that the C-shaped groove can open a certain angle, which is convenient for the rapid insertion of the headrest tube of the seat bracket, thereby improving the assembly efficiency of the seat bracket. At the same time, by adding the third support seat 10, the backrest plate of the seat bracket can be assembled and connected during welding, thereby reducing the process steps of the seat bracket and further improving the welding and production efficiency of the seat bracket.
