[0051] like Figure 1 , Figure 2 , Figure 5 As shown, the vehicle side protection transfer welding system includes:

[0052] Supporting ground rail 32, arranged transversely;

[0053] The transfer robot 31 is driven to move on the supporting ground rail 32 and moves through the storage rack 20 and the clamping component 50 in sequence;

[0054] The finished product shelf 60 is located on the longitudinal side of the supporting ground rail 32 and opposite to the clamping member 50;

[0055] The welding robot 40 is located near the middle of the clamping component 50;

[0056] The clamping component 50 comprises a support platform 53 driven to rotate about a transverse axis, and a plurality of clamping components 54 independently driven to move transversely and located on the support platform 53;

[0057] Each clamping assembly 54 comprises a clamping base plate 58, a first assembly and a second assembly which are both mounted on the clamping base plate 58;

[0058] The first assembly is used for clamping the crossbar 11, and is a pair and arranged symmetrically in the longitudinal direction. Each set of the first assembly comprises a first slider 543 driven to move longitudinally, a first cylinder 544 with a double output structure located on the first slider 543, and a clamping block 545 connected to the output end of the first cylinder 544;

[0059] The second component is close to the first component and is used for pressing the bending rod 12. It has a plurality of first support plates 56 arranged longitudinally and receiving the bending rod 12. One of the first support plates 56 is driven to move longitudinally and is turned over and pressed by the presser 57.

[0060] Specifically, the support ground rail 32 is used for the lateral movement of the transfer robot 31, so that the transfer robot 31 can move from the finished product shelf 60 to the clamping component 50 and the finished product shelf 60, that is, it can move to each process;

[0061] The storage rack 20 includes racks for placing the crossbar 11, the bending rod 12, and other parts, each rack is independent of each other and is arranged in a zone on the longitudinal side of the supporting ground rail 32 to facilitate identification and grasping by the transfer robot 31;

[0062] Both the transfer robot 31 and the welding robot 40 can be existing technologies, which can be positioned at various positions in a certain space through multi-degree-of-freedom movements such as rotation and linear movement. They mainly include a base, a multi-degree-of-freedom mechanical arm, and an output end. They are relatively mature products, and the specific structure is not further elaborated here; the output end of the transfer robot 31 is provided with a grasping assembly for grasping the cross bar 11, the bending rod 12, and the side protection 10 after welding is completed, and the output end of the welding robot 40 is provided with a welding assembly for welding; the grasping assembly can adopt the commonly used starting grasping, and the grasping load can meet the weight of the side protection 10. Taking arc welding and spot welding as examples, the welding assembly is composed of a welding power supply, a wire feeder, a welding gun, and other parts;

[0063] The finished product shelf 60 may be a mobile trolley capable of carrying a plurality of side guards 10; the finished product shelf 60 and the clamping component 50 are located on both sides of the longitudinal direction of the supporting ground rail 32, so as to facilitate the transfer robot 31 to rotate the side guard 10 from the clamping component 50 to the finished product shelf 60;

[0064] The clamping component 50 is used to position the crossbar 11 and the bending rod 12. The support platform 53 can rotate along a transverse axis. The multiple clamping components 54 independently move laterally on the support platform 53 and match the movement of the welding robot 40 to adjust the welding angle and position.

[0065] As an embodiment of the lateral movement of the clamping assembly 54, the clamping base plate 58 is assembled with the support platform 53 through a T-slot structure or a linear slide rail, and a moving assembly 55 can be provided on the clamping base plate 58, for example, the moving assembly 55 has a driving motor and a gear, and the gear is connected to the rack 35 on the support platform 53; in the second assembly, a groove for limiting the bending rod 12 is provided at the upper end of the first support plate 56, and the first support plate 56 is higher than the first cylinder 544 to ensure that the cross bar 11 can be overlapped on the bending rod 12 when it is placed above the first cylinder 544 waiting for the clamping block 545 to be positioned, so as to avoid the gap therebetween causing the welding quality to decrease; the clamping device 57 can be an existing structure, which mainly acts on the bending rod 12 by flipping the clamping block, such as a clamping block with a clamping cylinder, an L-shaped structure and a rotatable arrangement at one end, and the clamping cylinder is extended to drive the clamping block to flip, which will not be further elaborated here;

[0066] When the vehicle side protection transfer welding system is used, the cross bar 11 and the bending bar 12 can be placed on the corresponding shelves in advance. The transfer robot 31 is provided with a sensor that can identify the cross bar 11, the bending bar 12, and the side protection 10, and has the corresponding shelf position recognition function, so that the transfer robot 31 can automatically move and grab;

[0067] In the initial state, the support platform 53 is in a horizontal state. The positions of the clamping components 54 are adjusted according to the number of bending rods 12 and the adjacent spacing. The unused clamping components 54 are moved to the end side of the support platform 53 to avoid interference with other clamping components 54.

[0068] In the first assembly, the first slider 543 is correspondingly moved to a suitable position, so that the distance between a pair of first sliders 543 in the same assembly clamp assembly 54 matches the distance between a pair of cross bars 11, and the first sliders 543 on the same side of multiple assembly clamp assemblies 54 can receive one cross bar 11;

[0069] In the second assembly, one of the first support plates 56 is driven to move to a suitable position so that it and the other first support plates 56 can stably receive the bending rod 12;

[0070] The transfer robot 31 moves to the shelf of the bending rods 12, grabs the bending rods 12, and moves horizontally to the clamping component 50, and places the bending rods 12 at the second component, that is, the bending rods 12 are placed on multiple first support plates 56, and the clamping device 57 is actuated to position the bending rods 12 on the first support plates 56; when one bending rod 12 is pressed and positioned, the transfer robot 31 moves again to the shelf of the bending rods 12 to grab other bending rods 12, moves horizontally and places them at the second components of other clamping components 50, until the positioning of multiple bending rods 12 is completed;

[0071] The transfer robot 31 then moves to the shelf of the crossbar 11, grabs the crossbar 11, and moves horizontally to the clamping component 50, and places the crossbar 11 at the first component, that is, the crossbar 11 is placed above the multiple first sliders 543 on the same side and overlapped above the positioned bending rod 12; the corresponding first cylinder 544 drives a pair of clamping blocks 545 to approach each other to position the crossbar 11; when one crossbar 11 is positioned, the transfer robot 31 moves again to the shelf of the crossbar 11 to grab another crossbar 11, moves horizontally and places it at the second component of the clamping component 50 on the other side, until the positioning of a pair of crossbars 11 is completed;

[0072] When the pair of cross bars 11 and the plurality of bending bars 12 are positioned, the welding robot 40 performs welding. During the welding process, the plurality of clamping assemblies 54 can move synchronously to adjust the lateral welding position of the side guard 10, and the support platform 53 can rotate to adjust the circumferential welding angle of the side guard 10, and match the welding robot 40 to meet the welding of various angles and positions;

[0073] As explained, the actual side protection 10 includes not only the crossbar 11 and the bending rod 12, but also other parts. These parts are small in size and do not require additional positioning. They can be directly grasped by the transfer robot 31 to the corresponding position for welding;

[0074] When welding is completed, the clamp 57 and the first cylinder 544 move in the opposite direction, and the side protection 10 is in a non-fixed state. The transfer robot 31 grabs the side protection 10 onto the finished product shelf 60 and stacks them. When the side protection 10 on the finished product shelf 60 reaches a certain number, it is replaced.

[0075] The vehicle side protection transfer welding system uses the transfer robot 31 to move horizontally to grab the bending rod 12 and the cross bar 11 to the clamping component 50 for positioning in turn. After the welding robot 40 completes the welding of the cross bar 11 and the bending rod 12, they are grabbed to the finished product shelf 60 by the transfer robot 31, thereby realizing automatic transfer, grabbing and welding of the side protection 10, improving processing efficiency, and being suitable for batch processing; in addition, the clamping component 50 rotates along the horizontal axis through the support platform 53, multiple clamping components 54 move horizontally, and the first component and the second component correspondingly position the cross bar 11 and the bending rod 12. Under the condition of satisfying the positioning of different sizes of side protection 10, the adjustment of various welding angles of the side protection 10 is realized, thereby improving welding efficiency.

[0076] like Figure 3 As shown, further, the transfer robot 31 is installed on a supporting slide 36;

[0077] A moving motor 33 is provided on the supporting slide plate 36, and a laterally arranged rack 35 is provided on the supporting ground rail 32;

[0078] The output end of the moving motor 33 is connected to the driving wheel 34, and the driving wheel 34 is meshedly connected to the rack 35;

[0079] Specifically, after the moving motor 33 is started, it drives the driving wheel 34 to rotate, and the driving wheel 34 and the rack 35 are meshed with each other to realize the movement of the supporting slide 36 on the supporting ground rail 32;

[0080] To ensure the stability of movement, a slide groove may be provided at the lower end of the support slide plate 36 and matched with the upper slideway of the support ground rail 32, such as a T-slot structure or a linear slide rail;

[0081] like Figure 4 As shown, further, the finished product shelf 60 has a shelf base 61 and at least two shelf columns 62 that are laterally spaced apart on the shelf base 61;

[0082] Each shelf column 62 is provided with a plurality of shelf support rods 63 spaced apart from each other, and the shelf support rods 63 are arranged longitudinally and extend obliquely upward;

[0083] Specifically, in order to maintain the stability of the support of a pair of shelf columns 62, a connecting rod may be used to connect the upper ends of the shelf columns 62;

[0084] Shelf support rods 63 can be provided on both longitudinal sides of the shelf column 62; the transfer robot 31 grabs the side protection 10 after welding and transfers it to the finished product shelf 60, that is, the side protection 10 is located between the upper and lower shelf support rods 63, and the shelf column 62 is tilted upward to effectively prevent the side protection 10 from falling.

[0085] like Figure 5 , Figure 6 As shown, in a preferred embodiment, the first component further comprises a first motor 541 and a first screw 542;

[0086] The first motor 541 is fixed on the clamping base plate 58, and the output end is fixedly connected to the first screw rod 542;

[0087] The first slider 543 moves on the clamping base plate 58 through a linear slide rail and is threadedly connected to the first screw rod 542;

[0088] Specifically, after the first motor 541 is started, it drives the first screw 542 to rotate, so that the first slider 543 threadedly connected to the first screw 542 moves longitudinally, thereby driving the first cylinder 544 and the clamping block 545 on the first slider 543 to adjust their longitudinal positions.

[0089] Preferably, the second component further comprises a second motor 591, a second screw rod 592, and a second slider 593;

[0090] The second motor 591 is fixed on the clamping base plate 58, and the output end is fixedly connected to the second screw rod 592;

[0091] The second slider 593 moves on the clamping base plate 58 through a linear slide rail and is threadedly connected to the second screw rod 592; one of the first support plates 56 and the clamp 57 are both installed on the second slider 593;

[0092] Specifically, after the second motor 591 is started, it drives the second screw 592 to rotate, so that the second slider 593 threadedly connected to the second screw 592 moves longitudinally, thereby driving the first support plate 56 on the second slider 593 to adjust its longitudinal position;

[0093] Furthermore, the second component also has a second support plate located at the lateral side end of the clamping bottom plate 58;

[0094] The second support plate is used to receive the bent portion of the bending rod 12 and is turned over and pressed by the presser 57;

[0095] Specifically, the second support plate and the plurality of first support plates 56 can press the two parts of the bending rod 12 accordingly, and the structure of the second support plate is the same as that of the first support plate 56, that is, it has a groove for receiving the bending rod 12;

[0096] Further, each clamping base plate 58 is provided with a distance sensor;

[0097] The distance sensor is used to monitor the distance from the clamping base plate 58 to other clamping base plates 58 or the end side of the support platform 53;

[0098] After receiving the distance signal, the controller controls the lateral movement of the clamping assembly 54;

[0099] Specifically, when there are three groups of clamping assemblies 54, the distance sensor of the clamping base plate 58 at the middle position can monitor the distance between adjacent clamping base plates 58, and the distance sensors of the clamping base plates 58 at the other two positions can monitor the distance between adjacent clamping base plates 58 and the end side of the support platform 53;

[0100] The purpose of setting the distance sensor is to avoid collision when the clamping assembly 54 moves, so as to play a protective role; for example, when the clamping base plate 58 moves, when the distance sensor detects that the distance is less than the set range, the controller receives the distance signal and controls the lateral movement of the clamping assembly 54, which includes starting and stopping, and forward and reverse rotation.

[0101] like Figure 2 As shown, in the preferred embodiment, the flip assembly 51 has a fixed seat 52 and a driving assembly located in the fixed seat 52;

[0102] The two lateral ends of the support platform 53 are respectively provided with turning plates, each of which is rotatably mounted on the fixed seat 52 through a slewing bearing, and one of the turning plates is connected to the driving assembly;

[0103] Specifically, the flip assembly 51 can drive the support platform 53 and the clamping component 50 on the support platform 53 to flip at a certain angle, so as to adapt to the welding angle of the welding robot 40 and avoid the problem that some nodes cannot be contacted for welding;

[0104] The driving assembly may be a flip motor, a pinion fixedly connected to the output end of the flip motor, and a large gear located on the flip disk, wherein the large gear is mounted on the fixed seat 52 through a slewing bearing and meshedly connected with the pinion;

[0105] When the flip motor is started, the small gear and the large gear drive the flip plate and the support platform 53 on the flip plate to rotate to achieve angle adjustment; it is noted that in order to avoid normal use of the pneumatic and electric components of the support platform 53, the rotation angle of the support platform 53 is limited.

[0106] When the vehicle side protection transfer welding system is in use, the moving motor 33 is started, and the driving wheel 34 is engaged with the rack 35 on the supporting ground rail 32, so that the supporting slide plate 36 and the transfer robot 31 thereon move laterally;

[0107] The transfer robot 31 first moves to the storage rack 20, grabs the bending rod 12, and moves horizontally to the clamping component 50, and places the bending rod 12 at the second component, that is, the bending rod 12 is placed on multiple first support plates 56, one of the first support plates 56 can be longitudinally moved to adjust the position under the action of the second motor 591 driving the second screw 592, so that the multiple first support plates 56 can bear the bending rod 12, and then the clamp 57 rotates and presses down to position the bending rod 12; in addition, since the bending rod 12 is a bending structure, it can be placed on the second support plate at the same time and pressed by the clamp 57 until the positioning of the multiple bending rods 12 is completed;

[0108] The transfer robot 31 then moves to the storage shelf 20, grabs the crossbar 11, and moves horizontally to the clamping component 50, and places the crossbar 11 at the first component, that is, the first motor 541 is started, and the first motor 541 drives the second screw 592 to slide the first slider 543, and the crossbar 11 is placed above the multiple first sliders 543 on the same side and overlapped above the positioned bending rod 12; the corresponding first cylinder 544 drives a pair of clamping blocks 545 to approach each other to position the crossbar 11;

[0109] When the pair of cross bars 11 and the plurality of bending bars 12 are positioned, the welding robot 40 performs welding. During the welding process, the plurality of clamping assemblies 54 can move synchronously to adjust the lateral welding position of the side guard 10, and the support platform 53 can rotate to adjust the circumferential welding angle of the side guard 10, and match the welding robot 40 to meet the welding of various angles and positions;

[0110] When welding is completed, the clamp 57 and the first cylinder 544 act in the reverse direction, the side guard 10 is in a non-fixed state, and the transfer robot 31 grabs the side guard 10 onto the finished product shelf 60 and stacks them. When the number of side guards 10 on the finished product shelf 60 reaches a certain number, they are replaced;

[0111] After completing the welding process of a side guard 10, the transfer robot 31 moves laterally to re-grasp the bending rod 12 and the cross bar 11 to the clamping component 50 in turn, and performs clamping and positioning, thereby processing the side guard 10 in turn, with higher overall processing efficiency and degree of automation.
