Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sign welding, in particular to a multifunctional sign automatic welding device. BACKGROUND

[0002] With the development of industrial automation, the production requirements of signs are getting higher and higher, especially in the fields of identification, advertising and safety. The edges of the signs often need to be welded with edge guards for protection. Due to the variety of shapes of signs, manual welding is often used to process the edge guards, which are welded on the edges of the signs by electric welding.

[0003] In the traditional manual welding process, the edge guard needs to be pre-bent and attached to the edge of the sign with an arc-shaped edge. It is difficult for manual workers to hold and bend the edge guard, which may cause the stress of the welded edge guard to affect the overall deformation of the sign. Workers often face problems such as uneven welding skills and unstable welding points. In addition, manual welding may cause defects such as virtual welding, missed welding, and uneven welding marks when processing signs and frames, which may reduce the mechanical strength and aesthetic level of the signs. These defects not only affect the service life of the product, but also may cause safety accidents in actual application. Therefore, a multifunctional sign automatic welding device is needed. SUMMARY

[0004] The present application aims to provide a multifunctional sign automatic welding device to solve the problems mentioned in the background.

[0005] To solve the above technical problems, the present application provides the following technical solutions:

[0006] A multifunctional sign automatic welding device includes a positioning frame, a sign and an edge guard. The top of the positioning frame is vertically installed with a welding device. The side of the positioning frame away from the welding device is provided with a fixing device. The fixing device is fixedly connected with the sign through a suction cup. The sign is welded and connected with the edge of the sign through the welding device.

[0007] The welding device includes a movable side plate and a bending mechanism. One side of the bending mechanism is installed with an infrared range finder. The bending mechanism and the infrared range finder are installed on one side of the movable side plate. The top of the movable side plate is provided with a telescopic rod. The movable side plate is connected with the positioning frame through the telescopic rod. The bottom of the movable side plate is installed with a welding assembly.

[0008] The bending mechanism includes a clamping roller assembly, an abutting roller assembly, and a bending roller assembly. A groove is formed on one side of the movable side plate, and an electric push rod is installed on the inner wall of the groove. The clamping roller assembly, the abutting roller assembly, and the bending roller assembly are all movably connected to the movable side plate through the groove. One end of the edge protector passes sequentially through the clamping roller assembly, the abutting roller assembly, and the bending roller assembly. By passing one end of the edge protector sequentially through the clamping roller assembly, the abutting roller assembly, and the bending roller assembly, and controlling the electric push rod on the inner wall of the groove of the movable side plate, the relative positions of the clamping roller assembly, the abutting roller assembly, and the bending roller assembly are adjusted, bending and adjusting the fastened edge protector. This pre-bending of the edge protector improves the fit between the edge protector and the edge of the sign, thereby improving the welding quality of the sign edge.

[0009] The welding assembly includes an electric slide rail connected to the bottom of the movable side plate. A welding head is connected to one side of the electric slide rail via a slider, with one end of the welding head facing the inner angle between the sign and the edge guard. The electric slide rail adjusts the position and angle of the welding head, which then welds and fixes the sign and edge guard at their contact point. This welding process reduces the exposure of weld points, enhances the welding strength between the sign and the edge guard, reduces the need for grinding the outer weld points, and improves the overall aesthetics of the sign.

[0010] The fixing device consists of an electric suction cup, rods, and a drive motor. The drive motor is fixedly connected to the positioning frame, and the output shaft of the drive motor is fixedly connected to the electric suction cup via a coupling. The electric suction cup is fixedly connected to the sign. The sign is placed longitudinally on one side of the fixing device. The electric suction cup adheres to and fixes one side of the plate-shaped sign. The drive motor is controlled to rotate, and the angle of the sign on one side of the electric suction cup is adjusted, causing the entire sign to rotate. Simultaneously, the welding head welds the angle between the sign and the inner edge of the guard. While welding, the drive motor is controlled to rotate the sign, facilitating the falling off of welding slag and reducing its impact on the sign and guard, making cleaning easier.

[0011] The clamping roller assembly includes a positioning slide plate, one side of which is movably connected to a movable side plate. A rotating rod extends through the bottom of the positioning slide plate, and a deflection motor is connected to the top of the rotating rod. An electric slide groove is fixedly connected to the bottom of the rotating rod. An inner roller is connected to one side of the electric slide groove, and an outer roller is connected to the other side. A positioning roller is installed at the bottom of the outer roller, and the outer wall of the positioning roller abuts against the edge of the sign. Controlling the deflection motor to rotate the rotating rod causes the electric slide groove at the bottom to deflect. Simultaneously, the electric slide groove drives the inner and outer rollers to deflect synchronously. At the same time, the electric slide groove adjusts the distance between the inner and outer rollers. The inner roller, in conjunction with the outer roller, clamps and bends the edge. The positioning roller and the outer roller have equal cross-sectional diameters, ensuring that while one side of the positioning roller abuts against the sign, the edge is quickly aligned with the sign, improving the overall splicing and welding efficiency.

[0012] The movable side plate has three grooves on one side, equidistantly distributed about one side of the movable side plate. Each groove houses a clamping roller group, an abutting roller group, and a bending roller group, with the bending roller group having the same structure as the clamping roller group. During the welding process of the nameplate and edge protector, the electric suction cup and drive motor in the fixing device rotate the nameplate. Simultaneously, the inner and outer rollers in the clamping and bending roller groups rotate, rubbing and cleaning the outer wall of the edge protector. The positioning roller at the bottom of the outer roller rubs and cleans the edge of the nameplate, quickly performing pre-welding treatment on the nameplate and edge protector, reducing the impact of oxide layers and foreign matter on the welding effect.

[0013] A pressure sensor is installed between the contact roller and the groove. Two infrared rangefinders are installed, symmetrically arranged on both sides of the contact roller, with one end of each rangefinder facing the edge of the sign. The contact roller and the infrared rangefinders constitute a self-checking system. The sign is fixed to one side of the welding device using an electric suction cup. The drive motor rotates the sign, while the infrared rangefinders scan the edge of the sign to detect its flatness. When burrs appear on the edge of the sign, the drive telescopic rod pushes the positioning roller in the bending mechanism, causing the positioning roller to contact the edge of the sign and reciprocate to deflect the sign. The positioning roller quickly smooths the burrs, while the infrared rangefinders monitor and scan the flatness of the burrs. Simultaneously, the infrared rangefinders record and calculate the perimeter and shape of the sign's edge, and calculate the position and number of spot welds based on the bending shape of the sign's edge, reducing welding costs and enhancing weld strength.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0015] This invention utilizes a welding and fixing device to pre-bend and weld the edge protector and the sign, improving the fit between them, increasing welding strength, and avoiding the stress caused by bending the edge protector after welding. The welding components and bending mechanism weld the inner corners of the sign and edge protector, reducing the need for grinding the outer edges and improving the overall aesthetics of the sign. The fixing device ensures the vertical placement of the sign, facilitating the vertical fall of welding debris and reducing the impact of welding slag on the sign and edge protector, thus improving overall welding quality. The combination of clamping rollers, contact rollers, and bending rollers allows for rotation and adjustment of the sign while simultaneously cleaning its surface through friction, providing rapid pre-treatment and improving welding efficiency. Furthermore, by scanning the edge of the sign, the location and number of weld points are planned equidistantly, reducing welding costs and increasing the automation level of the device.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-5 The present invention provides the following technical solution:

[0032] A multifunctional automated welding device for signs includes a positioning frame, a sign 3, and a guard edge 4. A welding device 1 is vertically installed on the top of the positioning frame. A fixing device 2 is provided on the side of the positioning frame away from the welding device 1. The fixing device 2 is fixedly connected to the sign 3 by a suction cup. The sign 3 is welded to the edge of the sign 3 by the welding device 1.

[0033] The welding device 1 includes a movable side plate 101 and a bending mechanism 102. An infrared rangefinder 103 is installed on one side of the bending mechanism 102. Both the bending mechanism 102 and the infrared rangefinder 103 are installed on one side of the movable side plate 101. A telescopic rod 104 is provided on the top of the movable side plate 101. The movable side plate 101 is connected to the positioning frame through the telescopic rod 104. A welding assembly 105 is installed on the bottom of the movable side plate 101.

[0034] The bending mechanism 102 includes a clamping roller assembly 1021, a contact roller 1022, and a bending roller assembly 1023. A groove is provided on one side of the movable side plate 101, and an electric push rod is provided on the inner wall of the groove. The clamping roller assembly 1021, the contact roller 1022, and the bending roller assembly 1023 are all movably connected to the movable side plate 101 through the groove. One end of the guard edge 4 is sequentially connected to the clamping roller assembly 1021, the contact roller 1022, and the bending roller assembly 1023. One end of the edge protector 4 is sequentially passed through the clamping roller assembly 1021, the contact roller 1022, and the bending roller assembly 1023. The electric push rod on the inner wall of the groove of the movable side plate 101 is controlled to adjust the relative positions of the clamping roller assembly 1021, the contact roller 1022, and the bending roller assembly 1023. The fastened edge protector 4 is bent and adjusted, and the edge protector 4 is pre-bent to improve the fit between the edge protector 4 and the edge of the nameplate 3, thereby improving the welding quality of the edge of the nameplate 3.

[0035] The welding assembly 105 includes an electric slide rail 1051, which is connected to the bottom of the movable side plate 101. A welding head 1052 is connected to one side of the electric slide rail 1051 via a slider. One end of the welding head 1052 faces the inner angle between the sign 3 and the edge guard 4. The electric slide rail 1051 adjusts the position and angle of the welding head 1052, and the welding head 1052 welds and fixes the contact area between the sign 3 and the edge guard 4. This welding process reduces the exposure of weld points, enhances the welding strength between the sign 3 and the edge guard 4, reduces the need for grinding the outer weld points, and improves the overall aesthetics of the sign.

[0036] The fixing device 2 consists of an electric suction cup, rods, and a drive motor. The drive motor is fixedly connected to the positioning frame, and the output shaft of the drive motor is fixedly connected to the electric suction cup via a coupling. The electric suction cup is fixedly connected to the nameplate 3. The nameplate 3 is placed longitudinally on one side of the fixing device 2. The electric suction cup adheres to and fixes one side of the plate-shaped nameplate 3. The drive motor is controlled to rotate, and the angle of the nameplate 3 on one side of the electric suction cup is adjusted, causing the nameplate 3 to rotate as a whole. At the same time, the welding head 1052 welds the inner angle between the nameplate 3 and the edge guard 4. While welding, the drive motor is controlled to rotate the nameplate 3, which facilitates the falling off of welding slag, reduces the impact of welding slag on the nameplate 3 and the edge guard 4, and facilitates cleaning.

[0037] The clamping roller assembly 1021 includes a positioning slide plate 10211. One side of the positioning slide plate 10211 is movably connected to the movable side plate 101. A rotating rod 10212 passes through the bottom of the positioning slide plate 10211. A deflection motor 10213 is connected to the top of the rotating rod 10212. An electric slide groove 10214 is fixedly connected to the bottom of the rotating rod 10212. An inner roller 10215 is connected to one side of the electric slide groove 10214. An outer roller 10216 is connected to the other side of the electric slide groove 10214. A positioning roller 10217 is installed at the bottom of the outer roller 10216. The outer wall of the positioning roller 10217 abuts against the edge of the nameplate 3. The deflection motor 10213 controls the rotation of the rotating rod 10212, which drives the electric slide 10214 at the bottom to deflect. At the same time, the electric slide 10214 deflects, which drives the inner roller 10215 and the outer roller 10216 to deflect synchronously. Simultaneously, the electric slide 10214 controls the adjustment of the distance between the inner roller 10215 and the outer roller 10216. The inner roller 10215 and the outer roller 10216 clamp and bend the edge guard 4. The positioning roller 10217 and the outer roller 10216 have the same cross-sectional diameter, so that one side of the positioning roller 10217 contacts the nameplate 3, while controlling the edge guard 4 to quickly align with the nameplate 3, thereby improving the efficiency of the overall splicing and welding.

[0038] Three grooves are provided on one side of the movable side plate 101, and the three grooves are equidistantly distributed about one side of the movable side plate 101. The three grooves are respectively equipped with a clamping roller group 1021, a contact roller 1022, and a bending roller group 1023. The bending roller group 1023 has the same structure as the clamping roller group 1021. During the welding process of the nameplate 3 and the edge guard 4, the electric suction cup and drive motor in the fixing device 2 drive the nameplate 3 to rotate. At the same time, the inner roller 10215 and the outer roller 10216 in the clamping roller group 1021 and the bending roller group 1023 rotate to rub and clean the outer wall of the edge guard 4. The positioning roller 10217 at the bottom of the outer roller 10216 rubs and cleans the edge of the nameplate 3. The nameplate 3 and the edge guard 4 are quickly pre-treated for welding, reducing the impact of oxide layer and foreign matter on the welding effect.

[0039] A pressure sensor is provided between the contact roller 1022 and the groove. Two infrared rangefinders 103 are provided, and the two infrared rangefinders 103 are symmetrically arranged about the two sides of the contact roller 1022. One end of the infrared rangefinder 103 is facing the edge of the sign 3. The contact roller 1022 and the infrared rangefinders 103 constitute a self-testing system. The nameplate 3 is fixed to one side of the welding device 1 by an electric suction cup. The drive motor rotates the nameplate 3, and the infrared rangefinder 103 scans the edge of the nameplate 3 to detect the flatness of the edge. When burrs appear on the edge of the nameplate 3, the telescopic rod 104 is driven to push the positioning roller 10217 in the bending mechanism 102, so that the positioning roller 10217 abuts against the edge of the nameplate 3 and deflects the nameplate 3 back and forth. The positioning roller 10217 quickly processes and flattens the burrs. At the same time, the infrared rangefinder 103 monitors and scans the flatness of the burrs. While scanning, the infrared rangefinder 103 records and calculates the perimeter shape of the edge of the nameplate 3. At the same time, it calculates the position and number of spot welding points based on the bending shape of the edge of the nameplate 3, thereby reducing the cost of welding and enhancing the strength of the weld.

[0040] Working principle of the invention:

[0041] First, the sign 3 is fixed to one side of the welding device 1 by an electric suction cup. The drive motor rotates the sign 3, and at the same time, the infrared rangefinder 103 scans the edge of the sign 3 to detect the flatness of the edge of the sign 3. When burrs appear on the edge of the sign 3, the telescopic rod 104 is driven to push the positioning roller 10217 in the bending mechanism 102, so that the positioning roller 10217 abuts against the edge of the sign 3 and deflects the sign 3 back and forth. The positioning roller 10217 quickly processes and flattens the burrs. At the same time, the infrared rangefinder 103 monitors and scans the flatness of the burrs. While scanning, the infrared rangefinder 103 records and calculates the perimeter shape of the edge of the sign 3, and calculates the position and number of spot welds based on the bending shape of the edge of the sign 3.

[0042] The cut-off edge segments are then welded and fixed sequentially.

[0043] After planning the position and number of weld points for equidistant welding, one end of the edge guard 4 is passed through the clamping roller group 1021, the contact roller 1022 and the bending roller group 1023 in sequence. Based on the data detected by the self-inspection system, the electric push rod on the inner wall of the groove of the movable side plate 101 is controlled to adjust the relative position of the clamping roller group 1021, the contact roller 1022 and the bending roller group 1023, and the fastened edge guard 4 is bent and adjusted. The edge guard 4 is pre-bent to improve the fit between the edge guard 4 and the edge of the nameplate 3.

[0044] The deflection motor 10213 rotates the rotating rod 10212, which drives the electric slide 10214 at the bottom to deflect. At the same time, the electric slide 10214 deflects, which drives the inner roller 10215 and the outer roller 10216 to deflect synchronously. At the same time, the electric slide 10214 adjusts the distance between the inner roller 10215 and the outer roller 10216. The inner roller 10215 and the outer roller 10216 clamp and bend the guard edge 4. The positioning roller 10217 and the outer roller 10216 have the same cross-sectional diameter, so that while one side of the positioning roller 10217 is in contact with the nameplate 3, the guard edge 4 is quickly aligned with the nameplate 3.

[0045] The welding assembly 105 controls the inner corner welding of the sign and the edge protection, while the sign 3 is rotated by the fixing device 2;

[0046] During the welding process of the nameplate 3 and the edge guard 4, the electric suction cup and drive motor in the fixing device 2 drive the nameplate 3 to rotate. At the same time, the inner roller 10215 and the outer roller 10216 in the clamping roller group 1021 and the bending roller group 1023 rotate to rub and clean the outer wall of the edge guard 4. The positioning roller 10217 at the bottom of the outer roller 10216 rubs and cleans the edge of the nameplate 3. The nameplate 3 and the edge guard 4 are quickly pre-treated for welding to reduce the impact of oxide layer and foreign matter on the welding effect.
