[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention places the tent bracket to be welded and fixed above the two rotating positioning plates, then the positioning motor is powered on and starts to drive the positioning gear to rotate counterclockwise, so that the two synchronous gears rotate in opposite directions, thereby making the synchronous gear drive the positioning shaft and the two rotating positioning plates to rotate in opposite directions.

At this time, the axes of the two tent brackets coincide, and the tent bracket is quickly positioned to ensure that the tent bracket will not be offset after positioning, thereby avoiding problems in subsequent welding;

[0019] 2. The present invention realizes tension adjustment of the rotating belt by controlling the moving plate and the belt tension adjustment roller to move closer to or away from the rotating belt through the tension adjustment electric push rod, so that the rotating belt can bind or loosen the tent support. After the rotating belt binds and presses the tent support, the turning motor is used to drive the rotating gear and the transmission gear to rotate, so that the first drive shaft and the second drive shaft rotate towards each other, so that the first friction rotating roller and the second friction transmission roller rotate towards each other, and the rotating belt clamped between the first friction rotating roller and the second friction transmission roller runs between the first friction rotating roller and the second friction transmission roller. The running rotating belt is used to perform friction transmission on the tent support pressed by the rotating belt, so that the tent support rotates at a uniform speed, and the tent support is welded at a uniform speed in cooperation with the welding gun, so as to ensure the welding quality of the tent support after welding.

[0020] 3. The present invention utilizes a tension-adjusting electric push rod to control the moving plate and the belt tension-adjusting roller to move closer to or away from the rotating belt, thereby adjusting the tension of the rotating belt, so that the rotating belt can bind or loosen the tent bracket. After the rotating belt binds and presses the tent bracket, it is ensured that when the tent bracket is welded, fixed and rotated, the tent bracket will not jump or tilt upward, and the position of the tent bracket will not be offset during welding, which will cause problems in welding quality.

[0021] 4. The present invention utilizes a fixed electric telescopic rod to push the buffer block to fit the tent bracket, and uses the buffer block to push the tent bracket to slide inside the two rotating positioning plates, so that the ends of the two tent brackets fit each other, achieving direct docking and fixing of the tent brackets, and ensuring that there is no gap or looseness between the tent brackets.

[0034] like Figure 1 and Figure 6 As shown, two symmetrical fixed brackets 9 are fixed to the end faces of both ends of the fixing seat 1, a carrying plate 8 is fixed between the two symmetrical mounting grooves 7, the movable end of the carrying plate 8 is located above the two rotating positioning plates 601, and a buffer block 10 is fixed to the movable end of the carrying plate 8. The buffer block 10 is pushed to fit the tent bracket by using the fixed electric telescopic rod 4, and the tent bracket is pushed to slide on the inner side of the two rotating positioning plates 601 through the buffer block 10, so that the ends of the two tent brackets fit each other.

[0035] like Figure 1 and Figure 5 As shown, a welding gun 2 is installed on one side of the positioning groove 11, and the welding gun 2 includes a rotating rod 202, a lifting electric push rod 203 is fixed on the top of the rotating rod 202, and the bottom end of the rotating rod 202 is rotatably inserted in the fixing seat 1, a rotating motor 201 is fixed on the bottom end of the rotating rod 202, and a lifting block 204 is fixed on the top of the lifting electric push rod 203, a fixing rod 205 is fixed on one end of the lifting block 204, and a welding gun head 206 is fixed on the other end of the fixing rod 205, and a welding rod 207 is detachably installed in the welding gun head 206. The lifting block 204, the fixing rod 205, and the welding gun head 206 are kept parallel to the upper surface of the fixing base 1, and the lifting electric push rod 203 is used to control the rise and fall of the welding rod 207, so as to achieve the contact between the welding rod 207 and the tent bracket and the welding and fixing of the tent bracket by the welding rod 207. The lifting block 204, the fixing rod 205, and the welding gun head 206 that are kept parallel to the upper surface of the fixing base 1 ensure that the welding rod 207 is in vertical contact with the tent bracket, avoiding the welding point of the welding rod 207 between the welding tents from being offset, thereby ensuring the welding quality of the tent bracket.

[0036] like Figure 1 , Figures 7 to 9As shown, a welding rotating assembly 5 is installed on the inner side of the mounting groove 7, and the welding rotating assembly 5 includes a flip motor 510, which is fixed inside the fixing seat 1, and a rotating gear 511 is fixed on the output shaft end of the flip motor 510, and two transmission gears 512 are provided on one side of the rotating gear 511, and the two transmission gears 512 are meshed with each other, and the transmission gear 512 at the lower position is meshed with the rotating gear 511, and the second driving shaft 509 is axially penetrated and fixed on the lower transmission gear 512, and a second friction transmission roller 508 is fixed on the outer side of the second driving shaft 509, and the first driving shaft 507 is axially penetrated and fixed on the upper transmission gear 512, and a first friction rotating roller 506 is fixed on the outer side of the first driving shaft 507, A rotating belt 501 is clamped and installed between a friction rotating roller 506 and a second friction transmission roller 508. Both ends of the first drive shaft 507 and the second drive shaft 509 are rotatably inserted into the inner wall of the installation groove 7. The ends of the first drive shaft 507 and the second drive shaft 509 are connected to the fixed seat 1 through roller bearings. The turning motor 510 is used to drive the rotating gear 511 and the transmission gear 512 to rotate, so that the first drive shaft 507 and the second drive shaft 509 rotate in the same direction, thereby making the first friction rotating roller 506 and the second friction transmission roller 508 rotate in the same direction, and making the rotating belt 501 clamped between the first friction rotating roller 506 and the second friction transmission roller 508 run between the first friction rotating roller 506 and the second friction transmission roller 508.

[0037] Part of the rotating belt 501 is located outside the installation groove 7 and on the two rotating positioning plates 601. The rotating belt 501 located above the two rotating positioning plates 601 passes through the reserved groove 602 on the sides of the two rotating positioning plates 601. The rotating belt 501 passes over the two rotating positioning plates 601, which can restrain the tent bracket placed on the inner side of the two rotating positioning plates 601 downward to ensure that the tent bracket will not jump or warp upward.

[0038] A plurality of rotating positioning rods 502 are provided on the inner side of the bottom end of the rotating belt 501, and both ends of the rotating positioning rods 502 are rotatably connected to the inner wall of the mounting groove 7. The rotating positioning rods 502 are used to support the rotating belt 501 from the inside to prevent the rotating belt 501 from loosening and failing to tighten the tent support.

[0039] Belt tension adjusting rollers 503 are provided on both sides of the rotating belt 501, and a movable plate 504 is installed on the outer side of the belt tension adjusting roller 503. The belt tension adjusting roller 503 is rotatably connected to the movable plate 504, and a tension adjusting electric push rod 505 is fixed between the movable plate 504 and the mounting groove 7. The tension adjusting electric push rod 505 is used to control the movable plate 504 and the belt tension adjusting roller 503 to move closer to or away from the rotating belt 501, so as to adjust the tension of the rotating belt 501, so that the rotating belt 501 can bind or loosen the tent support.

[0040] Working principle: First, place the two tent brackets to be welded and fixed on the inner side of the two rotating positioning plates 601, then the positioning motor 604 is powered on and started to drive the positioning gear 606 to rotate counterclockwise. When the positioning gear 606 rotates, it drives the synchronous gear 607 directly meshing with it to rotate, so that another synchronous gear 607 rotates at the same time. At this time, the two synchronous gears 607 drive the two rotating positioning plates 601 to rotate towards each other at the same time through the positioning shaft 603. The rotating positioning plates 601 change from a horizontal state to an inclined state. The inclined rotating positioning plates 601 cause the tent bracket to slide to the middle of the two rotating positioning plates 601. The axes of the two tent brackets remain coincident after the two rotating positioning plates 601 rotate and tilt. Then the positioning motor 604 is powered off and stops running.

[0041] At this time, the tension-adjusting electric push rod 505 is powered on and started, and pushes the moving plate 504 and the belt tension-adjusting roller 503 toward the rotating belt 501. The two belt tension-adjusting rollers 503 squeeze the rotating belt 501 toward the middle, so that the tension of the rotating belt 501 is tightened. The tightened rotating belt 501 applies pressure from top to bottom to the tent support, and presses the tent support between the two rotated rotating positioning plates 601. Then, the fixed electric telescopic rod 4 is powered on and started, and drives the buffer pad 10 to approach the end of the tent support. The buffer pad 10 is used to push the tent support to slide inside the two rotating positioning plates 601 until the ends of the two tent supports fit each other. The fixed electric telescopic rod 4 is powered off and stops pushing the buffer pad 10 to move.

[0042] Next, the lifting electric push rod 203 is powered on and started, and drives the lifting block 204, the fixing rod 205, and the welding gun head 206 to move downward, so that the welding rod 207 moves downward with the welding gun head 206 until the welding rod 207 fits the connection between the ends of the two tent brackets. At this time, the ends of the tent brackets are welded and fixed by the welding rod 207. At the same time of welding, the flip motor 510 is powered on and started to drive the transmission gear 512 to rotate, so that the two rotating gears 511 rotate at the same time. When the two rotating gears 511 rotate, they respectively drive the first drive shaft 507 and the second drive shaft 509 to rotate, so that the first friction rotating roller 506 and the second friction transmission roller 508 rotate at the same time and in opposite directions.

[0043] The friction force of the first friction rotating roller 506 and the second friction transmission roller 508 on the rotating belt 501 is utilized to make the rotating belt 501 rotate under the drive of the first friction rotating roller 506 and the second friction transmission roller 508. The rotating belt 501 in operation drives the tent support to rotate at a uniform speed on the inner side of the two rotating positioning plates 601 through friction. The welding rod 207 welds the end connection of the tent support that is rotating at a uniform speed, quickly positions, aligns and fixes the tent support that needs to be welded and fixed, and allows the tent support to rotate at a uniform speed after fixation, thereby ensuring the welding quality of the tent support, shortening the welding preparation time and improving the welding efficiency of the tent support.

[0044] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
