[0020] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] Reference Figures 1 to 3 As shown, the utility model provides a product transmission line of a welding machine, in one embodiment, comprising a product transmission track 1; a transmission groove is opened at the top of the product transmission track 1 along its length direction; a plurality of first side positioning mechanisms 2 are installed at intervals on one side of the product transmission track 1 in the length direction, and a top clamping mechanism 3 is also installed on some of the first side positioning mechanisms 2; the first side positioning mechanism 2 comprises a first fixed bottom plate 21 connected to one side of the product transmission track 1, a first fixed vertical plate 22 connected to the top of one end of the first fixed bottom plate 21, a first slide rail arranged on the first fixed bottom plate 21 perpendicular to the length direction of the product transmission track 1, and a first side positioning block 23 slidably connected to the first slide rail; a first spring 24 is also connected between one end of the first side positioning block 23 and one side of the first fixed vertical plate 22, and the other end of the first side positioning block 23 extends to the upper side of the transmission groove.

[0022] Continue to refer to Figures 1 to 3 As shown, in order to meet the needs of multi-point welding of products, in this embodiment, a plurality of welding positions are provided on one side of the product transmission track 1, and a welding head (not shown in the figure) is placed at each welding position. Each welding head welds one of the welding points of the product respectively, so that the carrier carrying the product will move to different welding positions when the product transmission track 1 moves, thereby realizing multi-point welding of the product; in this embodiment, five groups of welding heads are provided, and a top clamping mechanism 3 is installed on the first side positioning mechanism 2 under each welding head to clamp and position the product for easy welding.

[0023] At the same time, it also includes a product transport mechanism (not shown in the figure) arranged on the other side of the product transmission track 1; the product transport mechanism can push the carrier to move along the transmission groove, and the structure of the product transport mechanism is not limited to this. In a feasible embodiment, the product transport mechanism includes an X-axis translation mechanism, a Y-axis translation mechanism, a translation push plate, and a plurality of push rods installed at intervals on one side of the translation push plate; each push rod is located on one side of a carrier, so that with the mutual cooperation of the X-axis translation mechanism and the Y-axis translation mechanism, the carrier can be pushed to move through a plurality of push rods. In another feasible embodiment, manual pushing can also be directly adopted.

[0024] In addition, a positioning protrusion 25 is provided in the middle of one end portion of the first side positioning block 23 extending toward the upper side of the transmission slot, and the side surface of the positioning protrusion 25 is in an arc-shaped structure.

[0025] In this embodiment, a V-shaped groove is further provided at one end of the carrier corresponding to the positioning protrusion 25. When the carrier moves in the transmission groove, its end will generate a thrust on the first side positioning block 23, and the first side positioning block 23 will retreat and squeeze the first spring 24. Under the influence of the restoring force of the first spring 24, the first side positioning block 23 will push the carrier to move to one side of the transmission groove through the positioning protrusion 25 to complete the preliminary positioning of the side. At this time, if the carrier is in the welding position, the top clamping mechanism 3 will press and position the product so that the welding head can weld the product.

[0026] In one embodiment, the top clamping mechanism 3 includes a lifting clamping cylinder 31 installed on the other side of the first fixed vertical plate 22, a position sensor 32 installed on the top of the first side positioning block 23, and a clamping lower pressing plate 33 connected to the lifting clamping cylinder 31; one end of the clamping lower pressing plate 33 extends to the top of the transmission slot, and the end of the clamping lower pressing plate 33 extending above the transmission slot is also provided with a first avoidance hole 34. When the position sensor 32 detects that there is a product in front, the lifting clamping cylinder 31 drives the clamping lower pressing plate 33 to descend, thereby pressing the product on the carrier to limit the position, and the end of the clamping lower pressing plate 33 extending above the transmission slot is also provided with a first avoidance hole 34, and the first avoidance hole 34 is opened corresponding to the corresponding point to be welded of the product to form an avoidance, so as to facilitate welding of the welding head.

[0027] In one embodiment, it also includes a loading transmission line 4 arranged at one end of the product transmission track 1; a loading pushing mechanism 5 is also installed on one side of the loading transmission line 4; the loading pushing mechanism 5 includes a loading fixed frame 51 connected to one side of the loading transmission line 4, a loading pushing cylinder 52 installed on one side of the loading fixed frame 51 along the length direction of the product transmission track 1, a loading lifting cylinder 53 connected to the loading pushing cylinder 52, and a loading push rod 54 connected to the loading lifting cylinder 53 and located above the loading transmission line 4; the loading push rod 54 is L-shaped, the L-shaped horizontal end of the loading push rod 54 is connected to the loading lifting cylinder 53, and the L-shaped vertical end of the loading push rod 54 is extended downward.

[0028] The loading transmission line 4 adopts the transmission method of the motor transmission belt. The loading transmission line 4 can transfer the carrier carrying the product to the bottom of the loading pushing mechanism 5. The loading pushing cylinder 52 and the loading lifting cylinder 53 cooperate with each other to drive the loading push rod 54 to push the carrier onto the product transmission track 1.

[0029] At the same time, the first blocking mechanism 6 is also installed at one end of the product transmission track 1 close to the feeding transmission line 4; the first blocking mechanism 6 includes a blocking lifting cylinder 61 and a blocking rod 62 connected to the blocking lifting cylinder 61. The blocking mechanism can block the product before it reaches the specified position to prevent the product from entering the product transmission track 1 too early; at the same time, a material separation blocking cylinder 8 is also installed on one side of the feeding transmission line 4, and the material separation blocking cylinder 8 is arranged close to one end of the product transmission track 1. The material separation blocking cylinder 8 cooperates with the blocking lifting cylinder 61 to achieve the separation of the front and rear carriers.

[0030] In addition, it also includes a material unloading transmission line 7 arranged at the other end of the product transmission track 1. The material unloading transmission line 7 adopts the transmission mode of the motor transmission belt. After the product is welded, the product handling mechanism pushes the carrier onto the material unloading transmission line 7, and then the material unloading transmission line 7 transmits the product to the next process.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
