[0048] The length of the oblique edge 207 is greater than the length of the serrated edge 208 , and the length of the serrated edge 208 is much greater than the lengths of the first side edge 206 and the second side edge 209 .

[0049] like Figure 2 as well as Figure 3 As shown, the first conveying platform 11 has a first supporting platform 111 with a rectangular cross section and a first conveying track 112 arranged on the first supporting platform 111 and extending in a horizontal direction.

[0050] The first conveying track 12 has two side rails 1121 parallel to each other.

[0051] The first supporting platform 111 has a hollow space between two side rails 1121 at one end. The other end of the first conveying track 112 away from the hollow portion is a first feeding end 113 , and the end of the hollow portion away from the end of the first supporting platform 111 is a first pushing end 114 .

[0052] The direction from the first pushing end 114 to the first feeding end 113 is a first pushing direction A.

[0053] like Figure 2 as well as Figure 3 As shown, the first storage mechanism 12 includes a first storage chute 121 and a second storage chute 122. The first storage chute 121 and the second storage chute 122 are respectively arranged on both sides of the first conveying track 112, and are inclined at a certain angle to the first conveying platform 11, that is, in the horizontal direction, for storing the stacked first front swing arm connecting half 200.

[0054] Figure 6 It is a schematic diagram of the top view of the structure of the first material storage mechanism and the first front swing arm connecting half portion matching each other in an embodiment of the present invention.

[0055] like Figure 6 As shown, the first material storage chute 121 is in the shape of a column with a rectangular cross-section, one end of which is arranged on one side of one of the side rails 1121 at the first pushing end 114 of the first conveyor platform 11, and the other end is inclined in the direction away from the first feeding end 113, that is, the first material storage chute 121 and the first pushing direction A form an obtuse angle.

[0056] The first material storage chute 121 is fixed on the first supporting platform 111 through a fixing assembly 123. The fixing assembly 123 includes a fixing plate 1231, a first fixing member 1232 and a second fixing member 1233.

[0057] The fixing plate 1231 is fixed along the first pushing direction A to a side of the first material storage chute 121 of the first supporting platform 111 away from the first conveying track 112 .

[0058] The first fixing member 1232 is arranged on a side of the first material storage chute 121 away from the first pushing end 114, and includes a connecting portion 1234 and an adjusting portion 1235. The connecting portion 1234 is zigzag-shaped, one end of which is fixed to the first material storage chute 121 by two fixing screws 1234a, and the other end is arranged on a side away from the first conveying track 112.

[0059] One end of the adjusting portion 1235 is fixedly connected to one end of the connecting portion 1234 away from the first conveying rail 112, and includes a bending portion extending in the vertical direction toward the first supporting platform 111. The other end of the adjusting portion 1235 is plate-shaped and fixedly connected to the fixing plate 1231 by two fixing screws 1235a.

[0060] The second fixing member 1233 is arranged on one side of the first material storage chute 121 close to the first pushing end 113, and is step-shaped. One end is fixedly connected to the side of the first material storage chute 121 away from the first conveying track 112, and the other end is fixedly connected to the fixing plate 1231 by two fixing screws 1233a.

[0061] The angle between the first material storage chute 121 and the first pushing direction A, that is, the inclination angle of the first material storage chute 121 is adjustable. Specifically, by adding gaskets between the connecting surfaces of the first fixing member 1232 and the second fixing member 1233 and the fixing plate 1231 and then connecting them through fixing screws, that is, adjusting the height of the first fixing member 1232 and the second fixing member 1233 to fine-tune the inclination angle of the first material storage chute 121.

[0062] When it is necessary to reduce the angle between the first material storage chute 121 and the first pushing direction A, that is, to increase the distance between the end of the first material storage chute 121 away from the first pushing end 114 and the first supporting platform 111, a gasket is added between the adjusting part 1235 of the first fixing member 1232 and the fixed plate 1231; when it is necessary to increase the angle between the first material storage chute 121 and the first pushing direction A, a gasket is added between the second fixing member 1233 and the fixed plate 1231.

[0063] The second material storage chute 122 is arranged parallel to the first material storage chute 121 , and one end of the second material storage chute 122 is arranged on one side of another side rail 1121 at the first pushing end 114 , and includes a chute supporting portion 1221 and a chute limiting portion 1222 .

[0064] The chute limiting portion 1222 is columnar and is arranged parallel to the first material storage chute 121 , that is, it also forms an obtuse angle with the first pushing direction A.

[0065] The slide groove supporting portion 1221 is in a plate shape, one side of which is connected to the side of the slide groove limiting portion 1222 close to the first conveying platform 11 , and forms an obtuse angle with the slide groove limiting portion 1222 .

[0066] The second material storage chute 122 is also fixed to the other side rail 1121 of the first support 111 through a fixing component 123. The fixing component 123 is the same as the fixing component 123 of the first material storage chute 122, but in the opposite direction, that is, the inclination angle of the second material storage chute 122 can also be adjusted together with the first material storage chute 122.

[0067] Figure 7 It is a schematic cross-sectional structural diagram of a feeding device for the first front swing arm connecting half portion of an embodiment of the present invention (the first storage mechanism is not shown).

[0068] like Figure 6 as well as Figure 7 As shown, a storage cavity is formed between the first storage chute 121 and the second storage chute 122, and a plurality of first front swing arm connecting halves 200 are stacked and stored in the storage cavity.

[0069] The first material storage chute 121 is limited by the serrated edge 208 of the first bottom plate 201 of the first front swing arm connecting half 200, and the chute support 1221 of the second material storage chute 122 is matched with the oblique edge 207 of the first bottom plate 201 and is limited by the abutment, that is, the side plate 202 of the first front swing arm connecting half 200 is arranged close to the first conveying platform 11, and the second side plate portion 204 is arranged close to the second material storage chute 122.

[0070] The first front swing arm connecting half 200 is stacked at a certain angle to the first pushing direction A, that is, except for the lowest first front swing arm connecting half 200, the first bottom plate 201 of the remaining first front swing arm connecting half 200 is stacked at a smaller acute angle with the first supporting platform 111.

[0071] The bottom end of the first material storage mechanism 12 , that is, the end of the first front swing arm connecting half 200 close to the bottom is the first material discharge end 124 .

[0072] The first material-blocking mechanism 13 includes a first position-limiting member 131 and a second position-limiting member 132 . The first position-limiting member 131 and the second position-limiting member 132 are respectively disposed on two sides of the first material-discharging end 124 of the first material-storing mechanism 12 .

[0073] The first limiting member 131 is disposed on one side of the first material storage chute 121 close to the first material discharge end 124 , and includes a first material stopping fixing portion 1311 , a first material stopping extension portion (not shown in the figure) and a first material stopping limiting portion 1313 .

[0074] The first material-blocking fixing portion 1311 is in a plate shape and is fixedly connected to the fixing plate 1231 on the side of the first material storage chute 121 by screws.

[0075] The first material blocking extension part is arranged at one end of the first material blocking fixing part 1311 close to the first conveying track 112 and extends upward in the vertical direction.

[0076] The other end of the first material blocking extension part is provided with a first material blocking limiting part 1313. The first material blocking limiting part 1313 is strip-shaped extending in the horizontal direction, and its length direction is perpendicular to the first pushing direction A.

[0077] The second limiting member 132 is arranged on one side of the second material storage chute 122 close to the first discharging end 124 and includes a second material blocking fixing part 1321, a second material blocking extension part (not shown in the figure) and a second material blocking limiting part 1323.

[0078] The second material blocking fixing part 1321 is plate-shaped and is fixedly connected to the fixing plate 1231 on the side of the second material storage chute 122 by screws.

[0079] The second material blocking extension part is arranged at one end of the second material blocking fixing part 1321 close to the first conveying track 112 and extends upward in the vertical direction, and its height is equal to that of the first material blocking extension part.

[0080] The other end of the second material blocking extension part is provided with a first material blocking limiting part 1323. The first material blocking limiting part 1313 is strip-shaped extending in the horizontal direction. One end of the first material blocking limiting part 1313 far from the second material blocking extension part extends in the direction close to the first discharging end 124, and the included angle between its length direction and the length direction of the first material blocking extension part is equal to the included angle between the first side plate part 203 and the second side plate part 204 of the first front swing arm connecting half part 200.

[0081] As Figure 7 shown, if the heights of the first material blocking extension part and the second material blocking extension part, that is, the heights of the first material blocking limiting part 1313 and the second material blocking limiting part 1323 to the conveying table are H; the height of the side plate 202 of the front swing arm connecting half part 200, that is, the height from the topmost end of the lowermost first front swing arm connecting half part 200 in the first material storage mechanism 12 to the first conveying table 11 is h1; the height from the topmost end of the second-lowermost first front swing arm connecting half part 200 in the first material storage mechanism 12 to the first conveying table 11 is h2, then h1 < H < h2.

[0082] Since h1 < H < h2, the first material blocking mechanism 13 blocks the second-lowermost first front swing arm connecting half part 200 in the first material storage mechanism 12, that is, the first material blocking limiting part 1313 of the first limiting member 131 abuts against the first side plate part 203 of this first front swing arm connecting half part 200 for limiting, and the second material blocking limiting part 1323 of the second limiting member 132 abuts against the second side plate part 204 for limiting.

[0083] At the same time, the first material blocking mechanism 13 does not block the lowermost first front swing arm connecting half 200. The lowermost first front swing arm connecting half 200 falls on the first pushing end 114 by gravity, and the length direction of its second side plate 204 is perpendicular to the first pushing direction A, and its hypotenuse 207 forms a certain angle with the first pushing direction A.

[0084] The pushing mechanism 14 is connected to the control device 4, and includes a driving member 141 and a first pushing member 142. The driving member 141 is disposed at an end of the first conveying platform 11 away from the first feeding end 113. In this embodiment, the driving member 141 is a cylinder.

[0085] The first pushing member 142 is connected to the driving member 141 and driven by the driving member 141 . The first pushing member 142 is plate-shaped and is disposed between the two side rails 1121 of the first conveying track 112 . The first pushing member 142 can be extended and retracted along the first pushing direction A.

[0086] The first pushing member 142 can move between the first pushing end 114 and the first feeding end 113 , and the end of the first pushing member 142 close to the first feeding end 113 is a pushing end 1421 , and the pushing end 1421 has an inclined edge matching the bevel 207 of the first front swing arm connecting half 200 .

[0087] The height range of the first pushing member 142 along the vertical direction is 2 / 3 to 3 / 4 of the thickness of the first bottom plate 201 of the first front swing arm connecting half 200 .

[0088] The first pushing member 142 is driven by the driving member 141, and its pushing end 1421 contacts the hypotenuse 207 of the first front swing arm connecting half 200 at the bottom of the first storage mechanism 12, thereby pushing the first front swing arm connecting half 200 from the first pushing end 114 to the first feeding end 113.

[0089] The positioning mechanism 15 is disposed at the first feeding end 113 , and includes a first positioning member 151 and a second positioning member 152 .

[0090] The first positioning member 151 and the second positioning member 152 are block-shaped and are respectively disposed at the end of the first conveying track 112 and at a side close to the first material storage chute 121 .

[0091] The first positioning member 151 is arranged along a direction perpendicular to the first pushing direction A, and the angle between the second positioning member 152 and the first positioning member 151 is equal to the angle between the first side plate portion 203 of the first front swing arm connecting half 200 and the serrated edge 208 .

[0092] When the connecting half 200 in the first front swing arm is pushed to the first feeding end 113 by the pushing mechanism 14, the first positioning member 151 contacts the first side plate portion 203 of the connecting half 200 of the first front swing arm and the second positioning member 152 contacts the serrated edge 208, so that the positioning mechanism 15 limits the connecting half 200 of the first front swing arm in the direction opposite to the first pushing direction A.

[0093] The first feeding end sensor 16 is connected to the control device 4 and is arranged at the first positioning member 151, and is used to sense whether the first front swing arm connecting half 200 is transported to the first feeding end 113 and taken away by the clamping device 3. The control device 4 controls the pushing mechanism 14 to push the first front swing arm connecting half 200 according to the sensing result of the first feeding end sensor 16, that is, when the first feeding end sensor 16 senses that there is no first front swing arm connecting half 200 on the first feeding end 113, the pushing mechanism 14 pushes; at the same time, when the first feeding end sensor 16 senses that there is a first front swing arm connecting half 200 on the first feeding end 113, the clamping device 3 grabs the first front swing arm connecting half 200 on the first feeding end 113.

[0103] A first rail portion 2111 and a second rail portion 2112 are provided at one end of the second supporting platform 211. The cross-sections of the first rail portion 2111 and the second rail portion 2112 are both rectangular and extend along the first horizontal direction. A gap is provided between the first rail portion 2111 and the second rail portion 2112, and the length of the first rail portion 2111 along the first horizontal direction is smaller than that of the second rail portion 2112.

[0104] The second conveying track 212 is disposed on the first track portion 2111 and the second track portion 2112 of the second supporting platform 211 .

[0105] The second conveying track 212 extends in the horizontal direction, and includes a first side rail 2121 arranged on the first track portion 2111 and a second side rail 2122 arranged on the second track portion 2112. The first side rail 2121 and the second side rail 2122 are both strip-shaped, which play a guiding and limiting role for the second front swing arm connecting half 300.

[0106] Ends of the first side rail 2121 and the second side rail 2122 are aligned with ends of the first rail portion 2111 and the second rail portion 2112 , respectively. That is, the length of the first side rail 2121 is shorter than that of the second side rail 2122 , and there is a gap between the first side rail 2121 and the second side rail 2122 .

[0107] A plate-shaped conveying rail body 2123 is also provided between the first side rail 2121 and the second side rail 2122 . The conveying rail body 2123 is provided on the second supporting platform 211 between the first side rail 2121 and the second side rail 2122 , and the end of the conveying rail body 2123 is aligned with the end of the second side rail 2122 .

[0108] The first side rail 2121, the second side rail 2122 and the conveying track body 2123 match the second front swing arm connecting half 300, that is, when the second front swing arm connecting plate portion 300 is conveyed on the second conveying track 212, its second bottom plate 301 is in contact with the conveying track body 2123, and the folding portion 305 of the second bottom plate 301 matches the gap between the conveying track body 2123 and the first side rail 2121, and the side panel folding portion 307 of the second front swing arm connecting half 300 and the side of the first side panel 302 away from the side panel folding portion 307 are respectively in contact with the second side rail 2122 and the first side rail 2121 for guiding and limiting.

[0109] An end of the second conveying track 212 away from the second supporting platform 211 is a second feeding end 215 , and an end of the second conveying track 212 close to the second supporting platform 211 is a second pushing end 216 .

[0110] The second material storage mechanism 22 is arranged above the second push end 216 of the second conveying track 212, and stores a plurality of second front swing arm connecting plate portions 300. Specifically, the second material storage mechanism 22 includes two material storage chutes 221 and two chute fixing members 222.

[0111] The two material storage chutes 221 are fixed on the surface of the second supporting platform 211 on both sides of the second pushing end 216 along the vertical direction through chute fixing members 222 respectively.

[0112] Fig.14 It is a schematic structural diagram of a material storage chute according to an embodiment of the present invention.

[0113] like Fig.14 As shown, the material storage chute 221 includes a first chute half 2211 , a second chute half 2212 , a chute connector 2213 and a limit screw 2214 .

[0114] The first slide slot half 2211 is arranged along the vertical direction, and its cross section is L-shaped, that is, it has a first slide slot plate 2216 and a second slide slot plate (not shown in the figure) that are perpendicular to each other. The first slide slot plate 2216 and the second slide slot plate are fixedly connected by fixing screws 2217 arranged along the vertical direction.

[0115] The second slide slot half 2212 is the same as the second slide slot plate, is disposed at an end of the first slide slot plate 2216 away from the second slide slot plate, and is perpendicular to the first slide slot plate 2216 in the horizontal direction.

[0116] The second slide groove half 2212 has a certain angle with the first slide groove plate 2216 in the vertical direction, that is, the gap between the top end of the second slide groove half 2212 and the top end of the first slide plate 2216, that is, the end away from the second pushing end 216 is larger than the gap between the bottom end of the second slide groove half 2212 and the bottom end of the first slide groove plate 2216, that is, the end close to the second pushing end 216.

[0117] Three slide slot connectors 2213 are disposed at one end of the second slide slot half 2212 close to the first slide slot plate 2216 .

[0118] The cross section of the slide connector 2213 is L-shaped, and includes a first connecting portion 2218 and a second connecting portion (not shown) perpendicular to the first connecting portion 2218 .

[0119] The second connecting portion is fixedly connected to the second sliding groove half 2212 by a fixing screw 2219 .

[0120] The first connection portion 2218 is perpendicular to the second connection portion and extends in a direction close to the first slide slot plate 2216 . The first connection portion 2218 is provided with a strip-shaped adjustment through hole 2215 .

[0121] The limit screw 2214 passes through the adjusting hole 2215 and is fixedly connected to the edge of the first slide plate 2216, so that the first slide plate 2216 is fixedly connected to the second slide half 2212, and because the distance between the second slide plate 2212 and the first slide plate 2216 changes with the change of height, the relative position of the limit screw 2214 and the adjusting hole 2215 in the horizontal direction changes with the change of the slide connector 2213 being set at different heights of the second slide half 2212.

[0122] By adjusting the relative position of the limit screw 2214 and the adjustment through hole 2215 , the distance between the first slide slot plate 2216 and the second slide slot half 2212 can be adjusted, thereby adjusting the width of the material storage slide slot 221 .

[0123] The two material storage chutes 221 are parallel to each other, and the grooves surrounded by the first chute half 2211 and the second chute half 2212 are arranged opposite to each other. The sides of the two material storage chutes 221 away from the second feeding end 215 are connected by two limiting beams 210 arranged at the bottom of the two material storage chutes 221. The two limiting beams 210 are parallel to each other and arranged in the horizontal direction.

[0124] The bottoms of the two material storage chutes 221 are respectively connected to the first track and the second track and are fixed to the second supporting platform 211 through a stepped chute fixing member 222 .

[0125] The oppositely arranged grooves of the two material storage chutes 221 cooperate to form a material storage cavity, in which a plurality of second front swing arm connecting halves 300 with second bottom plates 301 facing downward are stacked, and the bottom surface of the second bottom plate 301 of each second front swing arm connecting half 300 is abutted against the top edge of the second side plate 303 of the next second front swing arm connecting half 300, and a gap is formed by the inclined edge 306, that is, there is a gap between every two adjacent second front swing arm connecting halves 300.

[0126] The end of the storage chute 221 formed by the limiting beam 210 on the side away from the second pushing end 216 and the grooves of the two storage chutes 221 is the second unloading end 223 of the second storage mechanism 22, and the second pushing end 216 is arranged directly below the second unloading end 223.

[0127] The second material stopping mechanism 23 is used to support and control the falling of the second front swing arm connecting half 300 at the bottom of the second material storage mechanism 22, and includes two material stopping driving members 231 respectively arranged on both sides of the second conveying track 214 of the second unloading end 223.

[0128] The two material blocking driving members 231 are respectively connected with blocking rods 232 which are driven by the material blocking driving members 231 and can be extended and retracted in the horizontal direction. The two blocking rods 232 are arranged opposite to each other, and the blocking rods 232 are provided with a supporting surface near the unloading end 223 .

[0129] The two material blocking driving members 231 are respectively fixed to the first side rail 2121 and the second side rail 2122 of the second supporting platform 211 on the two sides away from the second material storage mechanism 22 through the material blocking fixing members 233 .

[0130] In this embodiment, the material blocking driving member 231 is a cylinder.

[0131] When the second material blocking mechanism 23 is in the blocking position, the shift rod 232 extends toward the center direction close to the second unloading end 223, and the supporting surface of the shift rod 232 contacts the second bottom plate 301 of the lowest second front swing arm connecting half 300 in the second material storage mechanism 22, thereby supporting the stacked second front swing arm connecting half 300.

[0132] When the second material blocking mechanism 23 is in the passing position, the blocking rod 232 is retracted into the material blocking driving member 231, so that the lowermost second front swing arm connecting half 300 falls at the second unloading end 223 by gravity.

[0133] The first conveying mechanism 24 is disposed directly below the second unloading end 223, and includes a first driving member 241 and a supporting member 242. In this embodiment, the first driving member 241 is a cylinder.

[0134] The supporting member 242 is driven by the first driving member 241 and can be extended and retracted in the vertical direction. The supporting member 242 is arranged directly below the unloading end 23 and can extend to the second unloading end 223 through the gap between the first track portion 2111 and the second track portion 2112 of the second conveying platform 21.

[0135] The supporting member 242 includes a push rod 2421 and a supporting portion 2422. The push rod 2421 can move in the vertical direction. The supporting portion 2422 is arranged at the top of the push rod 2421, and its cross section is concave, that is, the two ends of the top have supporting protrusions 2423 extending in the direction close to the second unloading end 223. The top surfaces of the two supporting protrusions 2423 are supporting surfaces, which contact and support the bottom surface of the bottom plate main body 304 of the second front swing arm connecting half 300.

[0136] When the second material blocking mechanism 23 is in the passing position, the lowermost second front swing arm connecting half 300 falls onto the supporting portion 2422 of the supporting member 242 by gravity, and then the front swing arm connecting half 300 is transported from the second unloading end 223 to the second pushing end 216 by the downward movement of the push rod 2421.

[0137] The second conveying mechanism 25 is disposed on the surface of the second supporting platform 211 . The second conveying mechanism 25 includes a second driving member 251 and a second pushing member 252 .

[0138] The second driving member 251 is disposed on the second supporting platform 211 , and a second pushing member 252 which can be extended and retracted in the horizontal direction is disposed at one end of the second driving member 251 close to the second pushing end 216 . The second pushing member 252 is driven by the second driving member 251 .

[0139] The second pushing member 252 has the same structure as the supporting member 242, and includes a push rod 2521 and a pushing portion 2522. The push rod 2521 can move in the horizontal direction. The pushing portion 2522 is arranged at the end of the push rod 2521, and its cross-section is concave, that is, the two ends of one side close to the second pushing portion 216 are respectively provided with a pushing protrusion 2523 extending toward the direction close to the second pushing portion 216.

[0140] When the first conveying mechanism 24 conveys the second front swing arm connecting half 300 from the second unloading end 223 to the second pushing end 216, the first side plate 302 of the second front swing arm connecting half 300 approaches the second pushing member 252, and the second pushing member 252 contacts the first side plate 302 and pushes the second front swing arm connecting half 300 from the pushing portion 216 to the second feeding end 215 through the second conveying track 214 through the push rod 2521, that is, moves along the second pushing direction B. The second conveying track 214 matches the second bottom plate 301 of the second front swing arm connecting half 300.

[0141] The first pushing direction A and the second pushing direction B are the same.

[0142] In this embodiment, the second feeding end sensor 26 , the unloading end sensor 27 , the second material blocking mechanism 23 , the first conveyor 24 and the second conveyor mechanism 25 are all electrically connected to the control device 4 .

[0143] The second feeding end sensor 26 is arranged at the second feeding end 215, and is used to sense whether the second front swing arm connecting half part 300 is conveyed to the second feeding end 223 and taken away by the clamping device 3. The second conveying mechanism 25 pushes according to the sensing result, that is, when the second feeding end sensor 26 senses that there is no second front swing arm connecting half part 300 on the second feeding end 223, the second conveying mechanism 25 pushes.

[0144] The unloading end sensor 27 is arranged at the second unloading end 223, and is used to sense whether there is a second front swing arm connecting half 300 on the first conveying mechanism 24. The second blocking mechanism 23 switches the blocking position and the passing position according to the sensing result, and the first conveying mechanism 24 also simultaneously retracts and extends the supporting member 242, that is, when the unloading end sensor 27 senses that there is no second front swing arm connecting half 300 on the first conveying mechanism 24, the second blocking mechanism 23 switches to the running position, and at the same time, the supporting member 242 of the first conveying mechanism 24 rises to the second unloading end 223.

[0145] Fig.15 Schematic diagram of the structure of the clamping device according to an embodiment of the present invention.

[0146] like Fig.15 As shown, the clamping device 3 includes a fixing portion 31 , a mechanical arm 32 , a clamping jaw mounting portion 33 , a first clamping jaw 34 and a second clamping jaw 35 .

[0147] The robot arm 32 is installed on the fixed part 31, and its end away from the fixed part 31 can move between the first feeding end 113 of the first front swing arm connecting half feeding device 1, the second feeding end 215 of the second front swing arm connecting half feeding device 2 and the welding equipment.

[0148] The clamping jaw mounting portion 33 is fixed to one end of the mechanical arm 32 away from the fixing portion 31 , and matches the first clamping jaw 34 and the second clamping jaw 35 .

[0149] The first clamping jaw 34 and the second clamping jaw 35 are mounted on the clamping jaw mounting portion 33 .

[0150] When the clamping device 3 is working, the first clamping jaw 34 clamps the second side plate portion 204 of the first front swing arm connecting half 200 from the first feeding end 113 of the first front swing arm connecting half feeding device 1, and the second clamping jaw 35 clamps the folded portion 305 of the second front swing arm connecting half 300 from the second feeding end 215 of the second front swing arm connecting half feeding device 2. After being clamped by the first clamping jaw 34 and the second clamping jaw 35, the first front swing arm connecting half 200 and the second front swing arm connecting half 300 do not interfere with each other.

[0151] The first clamp 34 and the second clamp 35 respectively clamp the first front swing arm connecting half 200 and the second front swing arm connecting half 300 and then transport the first front swing arm connecting half 200 and the second front swing arm connecting half 300 to the welding equipment through the robot arm 32.

[0152] The working process of the automatic welding machine feeding system 100 of this embodiment is as follows:

[0153] Step S1-1, a plurality of stacked first front swing arm connecting halves 200 are stored in the first storage mechanism 12 of the first front swing arm connecting half feeding device 1, and the first blocking mechanism 13 blocks the second to last first front swing arm connecting half 200 at the bottom, and the bottom first front swing arm connecting half 200 falls on the first pushing end 114 of the first conveying track 12 due to gravity;

[0154] Step S1-2, the first feeding end sensor 16 senses that there is no first front swing arm connecting half 200 on the first feeding end 113, and the control device 4 controls the first pushing member 142 of the pushing mechanism 14 to push the first front swing arm connecting half 200 from the first pushing end 114 to the first feeding end 113;

[0155] Step S1-3, the positioning mechanism 15 limits the first front swing arm connecting half 200 pushed to the first feeding end 113 so that it is fixed at the first feeding end 113;

[0157] Step S2-1, a plurality of stacked second front swing arm connecting half parts 300 are stored in the second storage mechanism 22 of the second front swing arm connecting half part feeding device 2, and the stop rod 232 of the second stop mechanism 23 is extended, that is, the second stop mechanism 23 is in a blocking position;

[0158] Step S2-2, the unloading end sensor 27 senses that there is no second front swing arm connecting half 300 on the first conveying mechanism 24, and the control device 4 controls the shift rod 232 of the second material blocking mechanism 23 to retract into the material blocking driving member 231, that is, the second material blocking mechanism 23 is in the passing position, so that the lowermost second front swing arm connecting half 300 falls by gravity, and at the same time, the control device 4 controls the supporting member 242 of the first conveying mechanism 24 to be driven to the unloading end 223 by the first driving member 241, and then the second front swing arm connecting half 300 falls onto the supporting member 242;

[0159] Step S2-3, after the lowermost second front swing arm connecting half 300 falls, the shift lever 232 extends toward the center of the second unloading end 223 again, so that the second blocking mechanism 23 switches to the blocking position. Since there is a gap between the two second front swing arm connecting half parts 300, the shift lever 232 can block the second front swing arm connecting half part 300 adjacent to the lowermost second front swing arm connecting half part 300;

[0160] Step S2-4, after the second material blocking mechanism 23 is switched to the blocking position, the first driving member 241 of the first conveying mechanism 24 drives the supporting member 242 to move downward, so that the second front swing arm connecting half 300 is conveyed to the second pushing portion 216;

[0161] Step S2-5, the second feeding end sensor 27 senses that there is no second front swing arm connecting half 200 on the second feeding end 215, and the control device 4 controls the second driving member 251 of the second conveying mechanism 25 to drive the second pushing member 252 to push the second front swing arm connecting half 300 to the second feeding end 223,

[0162] Step S3, the first feeding end sensor 16 senses that there is a first front swing arm connecting half 200 on the first feeding end 113, and the control device 4 controls the first clamping claw 34 of the clamping device 3 to grab the first front swing arm connecting half 200;

[0163] Step S4, the second feeding end sensor 27 senses that there is a second front swing arm connecting half 300 on the second feeding end 215, and the control device 4 controls the second clamping claw 35 of the clamping device 3 to grab the second front swing arm connecting half 300;

[0164] Step S5, the clamping device 3 transports the first front swing arm connecting half 200 and the second front swing arm connecting half 300 to the welding equipment.
