Description

Technical Field

[0001] The invention belongs to the technical field of welding gas station identification plates, and specifically relates to a welding device and a welding method for gas station identification plates. Background Art

[0002] Gas station signs are an important part of the visual image design of gas stations. They not only guide the route for vehicles and help car owners find gas stations, but also undertake multiple functions such as providing gas station information and ensuring refueling safety. Conventional gas station signs are usually erected near gas stations. In order to improve the readability of the signs, the height and volume of the signs are generally large, so they are usually welded in multiple pieces. For this reason, a welding device is needed to assist in welding the signs.

[0003] Since the height of the gas station signboard is relatively high, when welding the outer side thereof in the prior art, a scaffolding is built on the outer side of the signboard, that is, a suitable frame is provided on the outer side of the signboard, and the signboard is auxiliary fixed before being welded. Before welding, a relatively high frame needs to be built to meet the welding requirements, resulting in low overall welding efficiency.

[0004] At the same time, since the height of the gas station sign is relatively high and the outer side of the sign needs to be circumferentially welded, the existing technology generally requires welders to climb the frame of the outer side to a high place to achieve the welding process. However, the entire welding process is highly dangerous, and it is necessary to climb frames of different heights when welding at different heights, which urgently needs to be improved. Summary of the invention

[0005] The object of the present invention is to provide a welding device and a welding method for a gas station sign to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a welding device for a gas station sign, comprising a base, a non-slip seat is fixedly installed at the bottom end of the base, a longitudinal guide rail is fixedly installed in the middle of the rear end of the base, transverse guide rails are installed on the left and right sides of the base, a guide assembly is movably installed at the front end of the base, a self-clamping assembly is movably installed on the top of the base, an auxiliary clamping assembly is installed on the top of the self-clamping assembly, guide wheels are movably installed at equal distances in the middle of the base, a driving assembly is installed at the rear end of the longitudinal guide rail, the front end of the driving assembly is connected to the self-clamping assembly, a transmission assembly is provided on the outer side of the driving assembly, and one end of the transmission assembly is connected to the guide wheel in the middle;

[0007] The self-clamping assembly includes a movable block, a longitudinal guide block is fixedly installed at the bottom end of the movable block, the movable block is movably connected between the longitudinal guide block and the longitudinal guide rail, and the movable block moves forward and backward relative to the longitudinal guide rail. The self-clamping assembly also includes a transverse guide block, the transverse guide block is movably connected to the transverse guide rail, and the transverse guide block moves left and right relative to the transverse guide rail. The top ends of the two transverse guide blocks are both equipped with clamps, and the middle part of the movable block close to the base side is equipped with a pressure rod. The middle part of the self-clamping assembly away from the base side is connected with the driving assembly, the middle part of the top end of the clamping plate is connected with the auxiliary clamping assembly, and the inner side surface of the clamping plate is provided with an anti-slip groove.

[0008] Before welding the gas station sign, you need to prepare the corresponding welding machine and turn on the power of the device. At the same time, move the device to the position directly in front of the sign and fix the device to ensure that the device will not move. This completes the preparation before welding.

[0009] As a further technical solution of the present invention, the guide assembly includes a guide ramp, a clamping block is fixedly installed at the rear end of the guide ramp, the guide ramp is movably connected to the middle part of the front end of the base through the clamping block, and the guide ramp moves up and down relative to the base.

[0010] As a further technical solution of the present invention, an electromagnet located below the guide slope is installed at the front end of the anti-slip seat, ear plates are installed on the left and right sides of the guide slope and the left and right sides of the front end of the base, and a fixed sleeve is fixedly installed at the top end of the ear plate on one side of the base, and a movable rod is fixedly installed at the bottom end of the ear plate on one side of the guide slope.

[0011] As a further technical solution of the present invention, the movable rod and the fixed sleeve are movably connected, the bottom end of the movable rod is equipped with a limit plate located inside the fixed sleeve, the outer side surface of the movable rod is movably connected with a limit spring, the upper and lower ends of the limit spring are respectively connected with one end of the limit plate and one end of the inner cavity of the fixed sleeve, when the guide ramp is at the lowest point, the limit spring is in a maximum tension state, and the bottom end of the guide ramp and the electromagnet are adsorbed on each other, and the top end of the guide ramp and the top end of the base are on the same horizontal plane.

[0012] In the initial state, that is, when the sign is not completely transported to the top of the base, the guide assembly is in the initial state, that is, the bottom end of the guide slope and the electromagnet are mutually adsorbed, and the top end of the guide slope is flush with the top end of the base. At this time, the movable rod moves downward, and the limit spring is stretched and is in the limit stretching state;

[0013] When the sign is completely transported to the top of the base, the power supply of the electromagnet can be turned off, that is, the electromagnet no longer adsorbs the bottom end of the guide slope. At this time, the limit spring can be automatically reset, which can drive the movable rod to rise, and drive the guide slope to automatically rise until the guide slope rises to the highest point. At this time, the guide slope can block the front end of the sign, completing the limiting process.

[0014] As a further technical solution of the present invention, a first fixed seat is installed on both sides of the movable block, a second fixed seat is installed at the rear end of the splint, and the end of the second fixed seat away from the splint is movably connected to a connecting rod through a rotating shaft, and the other end of the connecting rod is movably connected to the first fixed seat.

[0015] When welding the signboard, the operator can transport the signboard to the guide slope through the inclined surface of the guide slope and move it to the top of the base until one end of the signboard contacts the pressure rod. After the contact is completed, the signboard continues to be pushed backward. At this time, the signboard can apply a backward force to the pressure rod, that is, the pressure rod moves backward. At this time, the longitudinal guide block is displaced relative to the longitudinal guide rail, that is, the movable block is displaced in the direction away from the base. At this time, the connecting rod is deflected accordingly, that is, it is deflected toward the middle. At this time, the splint is subjected to thrust, that is, the transverse guide block is displaced relative to the transverse guide rail, until the two splints are relatively close, and the two ends of the signboard are clamped, completing the limiting process of the left and right ends of the signboard.

[0016] As a further technical solution of the present invention, the driving assembly includes an oil storage pipe, the front end of the oil storage pipe is connected to the rear end of the longitudinal guide rail, the interior of the oil storage pipe is movably sleeved with a piston plate, the piston plate is displaced forward and backward relative to the oil storage pipe, the front end of the piston plate is fixedly connected to a piston rod, the front end of the piston rod sequentially passes through the front end of the oil storage pipe and the rear end of the longitudinal guide rail and is connected to the longitudinal guide block, the outer side surface of the piston rod is movably sleeved with a return spring, the front and rear ends of the return spring are respectively connected to one end of the inner cavity of the oil storage pipe and one end of the piston plate.

[0017] As a further technical solution of the present invention, the rear end of the oil storage pipe is fixedly connected to a power tank, the rear end of the piston plate and the rear end of the inner cavity of the oil storage pipe are filled with hydraulic oil, a pressure flap valve is installed between the oil storage pipe and the power tank, the interior of the power tank is movably connected to an impeller, the impeller is connected to a transmission assembly, and the rear end of the power tank is fixedly connected to a temporary storage box.

[0018] When the pressure rod moves backward, the movable block moves backward accordingly, which can push the piston rod to move backward. At this time, the return spring is stretched and drives the piston plate to move backward. At this time, the hydraulic oil inside the oil storage pipe is pressed out through the pressure flap valve, and after passing through the power tank, it enters the temporary storage box to complete temporary storage until the front end of the sign is limited by the guide assembly. At this time, the pressure rod cannot continue to move, and the hydraulic oil inside the temporary storage box can maintain the temporary storage state. At this time, the left and right ends of the sign can be limited by the left and right clamps, and the front and rear ends are respectively limited by one end of the guide assembly and one end of the pressure rod to complete the clamping process.

[0019] By abandoning the traditional frame fixing method, the sign is transported to the top of the base, and through the cooperation between the guide component and the self-clamping component, the sign can be automatically self-clamped by just pushing the sign into place. The whole process can be completed quickly without the need to build a frame like the traditional device. Multiple signboards can be welded and fixed in a short time, which significantly shortens the fixing time before welding and improves welding efficiency.

[0020] As a further technical solution of the present invention, the transmission assembly includes a power shaft, the middle part of the outer side surface of the power shaft is fixedly sleeved with the impeller, the left and right sides of the power shaft pass through the left and right ends of the power tank and are fixedly connected with a second transmission wheel, the transmission assembly also includes a main shaft located on the outer side surface of the base, the main shaft is fixedly sleeved with the guide wheel in the middle, the left and right ends of the main shaft pass through the left and right ends of the base and are fixedly connected with a first transmission wheel, a synchronous belt is movably sleeved between the first transmission wheel and the second transmission wheel, and the second transmission wheel is transmission-connected to the first transmission wheel via the synchronous belt.

[0021] After the welding of the identification plate is completed, when it needs to be discharged, the guide slope can be controlled to return to the initial state, that is, when the top of the guide slope is flush with the top of the base, the front end of the identification plate is no longer blocked by the limit, that is, no force is applied to the pressure rod. At this time, the reset spring can automatically reset and push the piston rod and the piston plate to automatically reset and move forward. At this time, the movable block drives the pressure rod to move forward and applies a forward thrust to the identification plate, and the two clamping plates move away from each other, releasing the side limit;

[0022] At the same time, the hydraulic oil inside the temporary storage box flows out and flows back to the inside of the oil storage pipe through the power tank. The impeller rotates due to the flow of hydraulic oil, and drives the power shaft in the middle to rotate. At this time, the second transmission wheel rotates accordingly, and drives the first transmission wheel to rotate through the synchronous belt. At this time, the main shaft rotates accordingly, and finally drives the guide wheel to rotate. At this time, the guide wheel can push the bottom end of the sign, and the sign is ejected.

[0023] By utilizing the limiting and fixing process of the identification plate, that is, the process of pushing the identification plate backward, the transfer of hydraulic oil is realized, and the upward displacement prevention device of the guide component is reset, that is, energy storage is realized through the above action, and when discharging, the energy can be released by resetting the guide component. The identification plate automatically pops up, and when discharging, it is only necessary to control the descent of the guide component. The whole process can be completed quickly, avoiding the problem of traditional frame method that the frame needs to be disassembled before discharging, and further improving the overall welding efficiency.

[0024] As a further technical solution of the present invention, the auxiliary clamping assembly includes a multi-stage hydraulic telescopic rod, the bottom end of the multi-stage hydraulic telescopic rod is connected to the top of the clamping plate, the output shaft of the multi-stage hydraulic telescopic rod is fixedly installed with a mounting frame, the top of the mounting frame is fixedly connected with a movable clamping plate, and a movable side plate is movably clamped between the tops of the two movable clamping plates.

[0025] After the fixation of the sign is completed, the welder can stand at one end of any movable clamping plate and drive the movable clamping plate to move up and down by opening the multi-stage hydraulic telescopic rod, so that the operator can move up and down. At this time, the operator can use the welding machine to weld both ends of the sign. If it is necessary to weld both ends of the sign, the movable side plate can be clamped between the two movable clamping plates, and the operator can stand on the top of the movable side plate to weld the front and back ends of the sign until the welding process of all positions is completed.

[0026] Through the initial process of limiting and fixing the signboard, the limiting of both ends of the signboard is completed, so that the operator can directly lift and lower the multi-stage hydraulic telescopic rod to quickly locate the welding position and complete the welding. At the same time, the two movable side panels can also be used to weld the two ends of the signboard to complete the rapid welding process, avoiding the problem of traditional welding methods requiring climbing to different heights, significantly reducing the risk and improving the overall welding efficiency.

[0027] A welding method for a welding device for a gas station sign, comprising the following steps:

[0028] S1: Before welding, first keep the guide slope at the lowest point, that is, keep the bottom of the guide slope and the electromagnet adsorbed to each other. At this time, the top of the guide slope can be kept on the same horizontal plane as the top of the base. At this time, the gas station sign can be moved, and the device can be pushed to the top of the base through the inclined surface of the guide slope, and then enter the top of the base through the guidance of the guide wheel, and continue to push the sign backward until one end of the sign contacts the pressure rod;

[0029] S2: At this time, the pressure rod is compressed and drives the movable block to move backward. At this time, the two clamping plates can be driven closer to each other under the linkage action of the connecting rod until the two clamping plates contact the two ends of the sign. At this time, the initial clamping process of the sign is completed. At this time, the power supply of the electromagnet can be turned off, the limit spring automatically resets, and the guide slope automatically rises. At this time, the left and right ends of the sign are limited by the clamping plates, and the front and rear ends are limited by the pressure rod and the guide slope, completing the clamping and fixing process;

[0030] S3: When welding is required at a high position of the sign, the welder can stand on one side of the movable clamping plate and open the multi-stage hydraulic telescopic rod to drive the movable clamping plate to rise to weld the left or right side of the sign. When welding the front and rear ends, the movable side plates at the corresponding positions can be installed to weld the front and rear ends of the sign until the welding process at each height is completed;

[0031] S4: After welding is completed, the guide slope can be controlled to reset, that is, the guide slope descends. At this time, the front end of the identification plate is no longer blocked, and the reset spring automatically resets. The hydraulic oil that was pressed into the temporary storage box in the early stage flows back to the inside of the oil storage pipe and drives the impeller to rotate. At this time, the power shaft rotates accordingly, and finally drives the guide wheel to rotate through the synchronous belt, and the identification plate is automatically pushed out through the forward displacement of the movable block to complete the discharge process.

[0032] The beneficial effects of the present invention are as follows:

[0033] 1. The present invention abandons the traditional frame fixing method and instead transports the identification plate to the top of the base. Through the cooperation between the guide component and the self-clamping component, the identification plate can be automatically self-clamped by only pushing the identification plate into place. The whole process can be completed quickly without the need to build a frame as in traditional devices. Multiple identification plates can be welded and fixed in a short time, which significantly shortens the fixing time before welding and improves welding efficiency.

[0034] 2. The present invention completes the limiting of both ends of the signboard through the initial limiting and fixing process of the signboard, so that the operator can directly locate the welding position and complete the welding quickly by lifting and lowering the multi-stage hydraulic telescopic rod. At the same time, the two ends of the signboard can also be welded by using two movable side panels to complete the rapid welding process, avoiding the problem of traditional welding methods requiring climbing to different heights, significantly reducing the risk, and improving the overall welding efficiency.

[0035] 3. The present invention realizes the transfer of hydraulic oil by utilizing the limiting and fixing process of the identification plate, that is, the process of pushing the identification plate backward, and resets the upward displacement prevention device of the guide component, that is, energy storage is realized through the above action, and when discharging, the energy can be released by resetting the guide component, and the identification plate automatically pops up. When discharging, it is only necessary to control the descent of the guide component. The whole process can be completed quickly, avoiding the problem of the traditional frame method that the frame needs to be disassembled before discharging, and further improving the overall welding efficiency.

[0048] The self-clamping component 6 includes a movable block 601, and a longitudinal guide block 602 is fixedly installed at the bottom end of the movable block 601. The movable block 601 is movably connected with the longitudinal guide rail 3 through the longitudinal guide block 602, and the movable block 601 moves forward and backward relative to the longitudinal guide rail 3. The self-clamping component 6 also includes a transverse guide block 603, which is movably connected with the transverse guide rail 4, and the transverse guide block 603 moves left and right relative to the transverse guide rail 4.

The middle part of the self-clamping component 6 away from the base 1 is connected to the driving component 10, and the middle part of the top end of the clamping plate 604 is connected to the auxiliary clamping component 7. The inner side of the clamping plate 604 is provided with an anti-slip groove.

[0049] Before welding the gas station sign, you need to prepare the corresponding welding machine and turn on the power of the device. At the same time, move the device to the position directly in front of the sign and fix the device to ensure that the device will not move. This completes the preparation before welding.

[0050] like Figure 2 and Figure 4 as well as Figure 6 and Fig. 9 As shown, the guide assembly 5 includes a guide slope 501, a clamping block 502 is fixedly installed at the rear end of the guide slope 501, the guide slope 501 is movably clamped with the middle part of the front end of the base 1 through the clamping block 502, the guide slope 501 moves up and down relative to the base 1, the front end of the anti-slip seat 2 is installed with an electromagnet 11 located below the guide slope 501, the left and right sides of the guide slope 501 and the left and right sides of the front end of the base 1 are installed with ear plates, and a fixing sleeve 503 is fixedly installed at the top of the ear plate on one side of the base 1, and a movable rod is fixedly installed at the bottom of the ear plate on one side of the guide slope 501 504, the movable rod 504 is movably connected with the fixed sleeve 503, the bottom end of the movable rod 504 is installed with a limit plate located inside the fixed sleeve 503, the outer side of the movable rod 504 is movably connected with a limit spring 505, the upper and lower ends of the limit spring 505 are respectively connected with one end of the limit plate and one end of the inner cavity of the fixed sleeve 503, when the guide slope 501 is at the lowest point, the limit spring 505 is in the maximum tension state, and the bottom end of the guide slope 501 and the electromagnet 11 are mutually adsorbed, and the top of the guide slope 501 and the top of the base 1 are on the same horizontal plane.

[0051] In the initial state, that is, when the sign is not completely transported to the top of the base 1, the guide assembly 5 is in the initial state, that is, the bottom end of the guide slope 501 and the electromagnet 11 are mutually attracted, and the top end of the guide slope 501 is flush with the top end of the base 1. At this time, the movable rod 504 moves downward, and the limit spring 505 is stretched and is in the ultimate stretching state;

[0052] When the sign is completely transported to the top of the base 1, the power supply of the electromagnet 11 can be turned off, that is, the electromagnet 11 no longer adsorbs the bottom end of the guide slope 501. At this time, the limit spring 505 can be automatically reset, which can drive the movable rod 504 to rise, and drive the guide slope 501 to automatically rise until the guide slope 501 rises to the highest point. At this time, the guide slope 501 can block the front end of the sign to complete the limiting process.

[0053] like Figure 1 and Figure 4 as well as Figure 5 As shown, a first fixed seat 605 is installed on both sides of the movable block 601, a second fixed seat 606 is installed at the rear end of the splint 604, and one end of the second fixed seat 606 away from the splint 604 is movably connected to a connecting rod 607 through a rotating shaft, and the other end of the connecting rod 607 is movably connected to the first fixed seat 605.

[0054] When welding the identification plate, the operator can transport the identification plate to the guide ramp 501 through the inclined surface of the guide ramp 501, and move it to the top of the base 1 until one end of the identification plate contacts the pressure rod 12. After the contact is completed, the identification plate continues to be pushed backward. At this time, the identification plate can apply a backward force to the pressure rod 12, that is, the pressure rod 12 is displaced backward. At this time, the longitudinal guide block 602 is displaced relative to the longitudinal guide rail 3, that is, the movable block 601 is displaced in the direction away from the base 1. At this time, the connecting rod 607 is deflected accordingly, that is, it is deflected toward the middle. At this time, the clamping plate 604 is subjected to the thrust, that is, the transverse guide block 603 is displaced relative to the transverse guide rail 4, until the two clamping plates 604 are relatively close, and the two ends of the identification plate are clamped, completing the limiting process of the left and right ends of the identification plate.

[0055] like Figure 1 and Figure 2 as well as Figure 7 and Figure 8As shown, the drive assembly 10 includes an oil storage pipe 101, the front end of which is connected to the rear end of the longitudinal guide rail 3, a piston plate 103 is movably sleeved inside the oil storage pipe 101, the piston plate 103 is displaced forward and backward relative to the oil storage pipe 101, a piston rod 102 is fixedly connected to the front end of the piston plate 103, the front end of the piston rod 102 passes through the front end of the oil storage pipe 101 and the rear end of the longitudinal guide rail 3 in sequence and is connected to the longitudinal guide block 602, and a return spring 104 is movably sleeved on the outer side of the piston rod 102. The front and rear ends of the return spring 104 are respectively connected to one end of the inner cavity of the oil storage pipe 101 and one end of the piston plate 103. The rear end of the oil storage pipe 101 is fixedly connected to the power tank 105. The rear end of the piston plate 103 and the rear end of the inner cavity of the oil storage pipe 101 are filled with hydraulic oil. A pressure flap valve is installed between the oil storage pipe 101 and the power tank 105. The power tank 105 is movably connected to an impeller 106, which is connected to the transmission assembly 9. The rear end of the power tank 105 is fixedly connected to a temporary storage box 107.

[0056] Embodiment: When the pressure rod 12 moves backward, the movable block 601 moves backward accordingly, which can push the piston rod 102 to move backward. At this time, the return spring 104 is stretched and drives the piston plate 103 to move backward. At this time, the hydraulic oil inside the oil storage pipe 101 is pressed out through the pressure flap valve, and after passing through the power tank 105, it enters the temporary storage box 107 to complete temporary storage until the front end of the sign is limited by the guide assembly 5. At this time, the pressure rod 12 cannot continue to move, and the hydraulic oil inside the temporary storage box 107 can maintain the temporary storage state. At this time, the left and right ends of the sign can be limited by the left and right clamps 604, and the front and rear ends are respectively limited by one end of the guide assembly 5 and one end of the pressure rod 12 to complete the clamping process.

The whole process can be completed quickly without the need to build a frame in the traditional way. Multiple identification plates can be welded and fixed in a short time, which significantly shortens the fixing time before welding and improves welding efficiency.

[0058] like Figure 1 and Figure 2 as well as Figure 7As shown, the transmission assembly 9 includes a power shaft 904, the middle part of the outer side surface of the power shaft 904 is fixedly sleeved with the impeller 106, the left and right sides of the power shaft 904 pass through the left and right ends of the power tank 105 and are fixedly connected with the second transmission wheel 902, the transmission assembly 9 also includes a main shaft 903 located on the outer side surface of the base 1, the main shaft 903 is fixedly sleeved with the guide wheel 8 in the middle, the left and right ends of the main shaft 903 pass through the left and right ends of the base 1 and are fixedly connected with the first transmission wheel 901, a synchronous belt 905 is movably sleeved between the first transmission wheel 901 and the second transmission wheel 902, and the second transmission wheel 902 is transmission-connected to the first transmission wheel 901 through the synchronous belt 905.

[0059] After the welding of the identification plate is completed, when it needs to be discharged, the guide slope 501 can be controlled to return to the initial state, that is, when the top of the guide slope 501 is in a flush relationship with the top of the base 1, the front end of the identification plate is no longer blocked by the limit, that is, no force is applied to the pressure rod 12, and the reset spring 104 can automatically reset and push the piston rod 102 and the piston plate 103 to automatically reset and move forward. At this time, the movable block 601 drives the pressure rod 12 to move forward and applies a forward thrust to the identification plate, and the two clamping plates 604 move away from each other, releasing the side limit;

[0060] At the same time, the hydraulic oil inside the temporary storage box 107 flows out and flows back to the inside of the oil storage pipe 101 through the power tank 105. The impeller 106 is rotated by the flow of the hydraulic oil and drives the middle power shaft 904 to rotate. At this time, the second transmission wheel 902 rotates accordingly and drives the first transmission wheel 901 to rotate through the synchronous belt 905. At this time, the main shaft 903 rotates accordingly and finally drives the guide wheel 8 to rotate. At this time, the guide wheel 8 can push the bottom end of the sign, and the sign is ejected.

[0061] By utilizing the limiting and fixing process of the identification plate, that is, the process of pushing the identification plate backward, the transfer of hydraulic oil is realized, and the upward displacement prevention device of the guide component 5 is reset, that is, energy storage is realized through the above action, and when discharging, the energy can be released by resetting the guide component 5, and the identification plate is automatically popped out. When discharging, it is only necessary to control the descent of the guide component 5. The whole process can be completed quickly, avoiding the problem of the traditional frame method that the frame needs to be disassembled before discharging, and further improving the overall welding efficiency.

[0062] like Figure 1 and Figure 2 as well as Figure 3As shown, the auxiliary clamping assembly 7 includes a multi-stage hydraulic telescopic rod 701, the bottom end of the multi-stage hydraulic telescopic rod 701 is connected to the top of the clamping plate 604, the output shaft of the multi-stage hydraulic telescopic rod 701 is fixedly installed with a mounting frame 702, the top of the mounting frame 702 is fixedly connected with a movable clamping plate 703, and a movable side plate 704 is movably clamped between the tops of the two movable clamping plates 703.

[0063] Embodiment: After the fixation of the sign is completed, the welding personnel can stand at one end of any movable clamping plate 703, and by opening the multi-stage hydraulic telescopic rod 701, the movable clamping plate 703 can be driven to move up and down to enable the operator to move up and down. At this time, the operator can use the welding machine to weld the two ends of the sign. If it is necessary to weld the two ends of the sign, the movable side plate 704 can be clamped between the two movable clamping plates 703, and the operator can stand on the top of the movable side plate 704 to weld the front and back ends of the sign until the welding process of all positions is completed.

[0064] Through the initial limiting and fixing process of the signboard, the limiting of both ends of the signboard is completed, so that the operator can directly locate the welding position and complete the welding by raising and lowering the multi-stage hydraulic telescopic rod 701. At the same time, the two ends of the signboard can also be welded using the two movable side panels 704 to complete the rapid welding process, avoiding the problem of traditional welding methods requiring climbing to different heights, significantly reducing the risk, and improving the overall welding efficiency.

[0065] A welding method for a welding device for a gas station sign, comprising the following steps:

[0066] S1: Before welding, first keep the guide slope 501 at the lowest point, that is, keep the bottom end of the guide slope 501 and the electromagnet 11 adsorbed to each other, then the top of the guide slope 501 can be kept on the same horizontal plane as the top of the base 1, then the gas station sign can be moved, and the device can be pushed to the top of the base 1 through the inclined surface of the guide slope 501, and then enter the top of the base 1 under the guidance of the guide wheel 8, and continue to push the sign backward until one end of the sign contacts the pressure rod 12;

[0067] S2: At this time, the pressure rod 12 is compressed and drives the movable block 601 to move backward. At this time, the two clamping plates 604 can be driven to move closer to each other under the linkage action of the connecting rod 607 until the two clamping plates 604 contact the two ends of the identification plate. At this time, the initial clamping process of the identification plate can be completed. At this time, the power supply of the electromagnet 11 can be turned off, the limit spring 505 automatically resets, and the guide slope 501 automatically rises. At this time, the left and right ends of the identification plate are limited by the clamping plates 604, and the front and rear ends are limited by the pressure rod 12 and the guide slope 501, completing the clamping and fixing process;

[0068] S3: When welding is required at a high position of the sign, the welder can stand on one side of the movable clamping plate 703 and open the multi-stage hydraulic telescopic rod 701 to drive the movable clamping plate 703 to rise to weld the left or right side of the sign. When welding the front and rear ends, the movable side plate 704 at the corresponding position can be installed to weld the front and rear ends of the sign until the welding process at each height is completed;

[0069] S4: After welding is completed, the guide slope 501 can be controlled to reset, that is, the guide slope 501 descends. At this time, the front end of the identification plate is no longer blocked, and the reset spring 104 automatically resets. The hydraulic oil that was previously pressed into the temporary storage box 107 flows back to the inside of the oil storage pipe 101 and drives the impeller 106 to rotate. At this time, the power shaft 904 rotates accordingly, and finally drives the guide wheel 8 to rotate through the synchronous belt 905, and automatically pushes the identification plate out through the forward displacement of the movable block 601, completing the discharge process.
