Description

Technical Field

[0001] This invention relates to the field of welding technology, specifically to a ceiling profile calibration welding device. Background Technology

[0002] Ceiling profiles are widely used in interior decoration. Their welding process usually involves vertically welding multiple short profiles (such as connecting pipes) to long profiles (such as keels) at certain intervals. Traditional welding methods often rely on operators climbing A-frame ladders on-site for high-altitude operations, which poses obvious safety hazards. Moreover, work efficiency is greatly affected by the operating space and the experience of the personnel.

[0003] While prefabrication and welding in the workshop can guarantee quality and efficiency, the resulting welded components are large, lack rigidity, are prone to deformation during transportation and handling, and are difficult to flexibly adjust to different site dimensions. Direct welding on the construction site presents challenges such as difficulty in moving equipment, inconvenient support positioning, and low calibration accuracy. Operators often need to repeatedly measure and draw lines to determine the welding position, which is not only time-consuming and labor-intensive but also prone to weld misalignment due to visual errors or improper operation, affecting the overall flatness and structural strength of the ceiling. Therefore, a specialized piece of equipment is needed that is flexible, easy to deploy on-site, and capable of rapid centering and calibration, as well as assisting in high-altitude welding. Summary of the Invention

[0004] The purpose of this invention is to provide a ceiling profile calibration and welding device to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a ceiling profile calibration and welding equipment, comprising a welding mechanism, a feeding mechanism and a calibration mechanism, wherein the welding mechanism and the feeding mechanism are mounted on a frame, and the welding mechanism, the feeding mechanism and the calibration mechanism are connected to a control system circuit;

[0006] The calibration mechanism includes a pair of traction components and a calibration circuit. The pair of traction components are symmetrically arranged in the frame. Each traction component includes a steel cable, a winding machine, and a support machine. The steel cable connects the winding machine and the support machine. The support machine is located outside the frame. The calibration circuit includes a pair of sliding rheostats. The pair of sliding rheostats are respectively arranged in the pair of winding machines. The operator places the long profile to be welded into the profile slide, and then connects the pair of calibration mechanisms to both ends of the long profile. The traction components drive the long profile to move quickly, and the calibration circuit quickly calibrates the center of the profile. The short profile is then brought into contact with the long profile through the feeding mechanism, and the welding mechanism then welds the short profile onto the long profile.

[0007] Furthermore, the frame includes a movable platform, the winding machine includes a drive unit and a take-up and unwinding roller, the drive unit is mounted on the movable platform, the movable platform is provided with a cylindrical cavity, the take-up and unwinding roller is disposed in the cylindrical cavity, the take-up and unwinding roller is connected to the drive unit, and one end of the steel cable passes through the movable platform and is connected to the take-up and unwinding roller.

[0008] Furthermore, the winding machine also includes a threaded baffle, which is disposed on the side of the take-up and untake-up rollers away from the drive component. The inner wall of the cylindrical chamber is provided with an internal thread, and the outer contour of the threaded baffle is provided with an external thread that matches the internal thread. The drive component drives the spline shaft to rotate, and the spline shaft drives the drum to rotate. When the drum drives the threaded baffle to rotate synchronously, the threaded baffle moves axially as it rotates along the internal thread.

[0009] Furthermore, the take-up and unwinding roller includes a splined shaft and a drum. The splined shaft is rotatably disposed in a cylindrical chamber, and one end of the splined shaft is connected to a drive component. The drum is slidably mounted on the splined shaft, and the diameter of the drum is smaller than the diameter of the cylindrical chamber. One end of the steel cable passes through the moving platform and is connected to the drum. The threaded baffle is disposed on the side of the drum away from the drive component. The drum moves axially during the take-up and unwinding of the steel cable, keeping the steel cable in a single layer and preventing the steel cable from crossing and tangling. This makes it easier to reflect the take-up and unwinding distance of the steel cable by the number of rotations of the drum.

[0010] Furthermore, the support machine includes a support body and a conical top body. The bottom of the support body is provided with an auxiliary wheel. The conical top body is connected to a steel cable and has a conical top body. The bottom of the conical top body is slidably connected to the support body. After the operator places the long profile into the profile slide, he first pulls the steel cable on one side out of the drum, inserts the conical top body on the conical top body into the end of the long profile, then pulls out the steel cable on the other side and inserts it into the conical top body. Then he loosens the fastening bolts so that the auxiliary wheel on the support body naturally touches the ground, and then tightens the fastening bolts to fix the conical top body on the support body.

[0011] Furthermore, the top of the support body is provided with a sliding groove that matches the cone top body, and the side wall of the support body is provided with a threaded hole that passes through the sliding groove. A fastening bolt is provided in the threaded hole, and the fastening bolt presses the cone top body. When a drum winds up the steel cable, the steel cable drags the cone top body to move, and the cone top body pushes the long profile to the other side. The drum on the other side passively releases the steel cable, and the support body supports the long profile to prevent the long profile on one side from tilting and touching the ground due to excessive weight.

[0012] Furthermore, the calibration circuit is a Wheatstone bridge circuit. The sliding rheostat element includes a sliding plate and a resistor. The resistor is axially arranged along the spline shaft. The sliding plate is located on the side of the drum away from the threaded baffle. The sliding plate is in contact with the resistor. The drum drives the sliding plate to move. The sliding plate slides on the resistor to change the resistance value in the calibration circuit. When the resistances of the two sliding rheostat elements are the same, that is, when the two drums drive the sliding plate to move the same distance, the bridge current in the Wheatstone bridge circuit is zero. When the control system detects that the bridge current is zero, the steel cables on both sides are released to the same length. The idler roller is located at the center of the long profile. By using the calibration circuit and a pair of traction components to cooperate with each other, the long profile can be quickly aligned and calibrated, so that the short profile can be quickly connected to the long profile for welding. There is no need for manual measurement and marking, which greatly improves the calibration accuracy and efficiency and reduces human error.

[0013] Furthermore, the frame also includes a back plate, on which both the feeding mechanism and the welding mechanism are mounted. The feeding mechanism includes a pair of moving modules, which are slidably connected to the back plate. The pair of moving modules are symmetrically arranged, and each moving module is provided with a transfer clamp. Each transfer clamp is provided with several limiting wheels, and each limiting wheel has a right-angle concave annular groove. The operator uses the control system to adjust the movement of the pair of moving modules. The pair of moving modules drives the limiting wheels on both sides to move closer together through the transfer clamp until the limiting wheels contact the short profile. The short profile slides down along the limiting wheels on both sides and finally falls onto the long profile. After welding, the pair of moving modules drives the limiting wheels on both sides to separate, releasing the short profile. The operator moves the long profile through the traction component to weld more short profiles onto the long profile.

[0014] Furthermore, the welding mechanism includes a rotating module rotatably connected to the back plate. The rotating module is located on the outer ring of the moving module, and at least one welding machine is mounted on the rotating module. The rotating module drives the welding machine to rotate, and the welding machine performs circumferential welding on the contact area between the short profile and the long profile. The feeding mechanism and the welding mechanism work together to realize automatic feeding, positioning, and peripheral welding of the short profile. Operators only need simple control to complete multiple sets of welding, ensuring uniform welds, improving welding speed and product quality, and is suitable for batch production and rapid on-site construction needs.

[0015] Furthermore, the bottom of the mobile platform is equipped with lockable casters, and a housing cover is provided at the mounting location of the drive component. A cylindrical welding pool and profile slide are also provided in the middle of the mobile platform. The profile slide is connected to the welding pool, and a support roller is provided in the welding pool. Several side clamping rollers are provided on both sides of the profile slide, and the side clamping rollers are connected to the mobile platform through elastic elements. The equipment is equipped with lockable casters and an expandable support mechanism, which facilitates movement and on-site fixation, reduces the need for operators to climb at heights, and lowers the risk of falls. At the same time, the support mechanism can stably support long profiles, preventing them from tilting or touching the ground during welding, thus improving operational stability.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The feeding mechanism and welding mechanism work together to realize automatic feeding, positioning and peripheral welding of short profiles. Operators only need simple control to complete multiple sets of welding, ensuring uniform welds, improving welding speed and product quality, and are suitable for batch production and rapid on-site construction needs.

[0018] 2. The calibration mechanism, composed of a traction component and a Wheatstone bridge circuit, can detect and adjust the length of the steel cables on both sides in real time, automatically positioning the center of the long profile to the welding station. This eliminates the need for manual measurement and marking, significantly improving calibration accuracy and efficiency and reducing human error.

[0019] 3. Equipped with lockable casters and an extendable support mechanism, it is easy to move and fix on site, reducing the need for operators to climb at heights and lowering the risk of falls. At the same time, the support mechanism can stably support long profiles, preventing them from tilting or touching the ground during welding, thus improving operational stability.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0029] Example: Figures 1-7 As shown, this invention provides a ceiling profile calibration and welding equipment, including a welding mechanism, a feeding mechanism, and a calibration mechanism. The welding mechanism and the feeding mechanism are mounted on a frame and are connected to a control system circuit. The calibration mechanism includes a pair of traction components and a calibration circuit. The pair of traction components are symmetrically arranged in the frame. Each traction component includes a steel cable 7, a winding machine, and a support machine. The steel cable 7 is connected between the winding machine and the support machine. The support machine is located outside the frame. The calibration circuit includes a pair of sliding rheostat elements, which are respectively arranged in the pair of winding machines. The bottom of the moving platform 1 is equipped with lockable casters 12. A housing cover 13 is provided at the mounting position of the driving component on the moving platform 1. The driving component is a servo motor 3. A cylindrical welding pool and a profile sliding section are also provided in the middle of the moving platform 1. The profile slide is connected to the welding pool, which is equipped with rollers 14. Several side clamping rollers 15 are installed on both sides of the profile slide. The side clamping rollers 15 are connected to the moving table 1 by elastic elements, which are springs. The operator places the long profile to be welded into the profile slide, and then connects a pair of calibration mechanisms to both ends of the long profile. The traction component drives the long profile to move quickly, and the calibration circuit quickly calibrates the center of the profile. The short profile is then brought into contact with the long profile through the feeding mechanism, and the welding mechanism welds the short profile to the long profile. Equipped with lockable casters 12 and deployable support mechanisms, it is easy to move and fix on site, reducing the need for operators to climb at heights and reducing the risk of falls. At the same time, the support mechanism can stably support the long profile, preventing it from tilting or touching the ground during the welding process, thus improving the stability of the operation.

[0030] The frame includes a moving table 1, and the winding machine includes a servo motor 3 and a take-up / unwinding roller. The servo motor 3 is mounted on the moving table 1, which has a cylindrical chamber. The take-up / unwinding roller is located in the cylindrical chamber and connected to the servo motor 3. One end of a steel cable 7 passes through the moving table 1 and is connected to the take-up / unwinding roller. The winding machine also includes a threaded baffle 6, which is located on the side of the take-up / unwinding roller away from the servo motor 3. The inner wall of the cylindrical chamber has an internal thread, and the outer contour of the threaded baffle 6 has an external thread that matches the internal thread. The take-up / unwinding roller includes a splined shaft 4 and a drum 5. The splined shaft 4 is rotatably mounted in the cylindrical chamber, and one end of the splined shaft 4 is connected to the servo motor 3. The servo motor 3 is connected to the drum 5, which is slidably mounted on the spline shaft 4. The diameter of the drum 5 is smaller than the diameter of the cylindrical chamber. One end of the steel cable 7 passes through the moving table 1 and is connected to the drum 5. The threaded baffle 6 is set on the side of the drum 5 away from the servo motor 3. The servo motor 3 drives the spline shaft 4 to rotate, and the spline shaft 4 drives the drum 5 to rotate. When the drum 5 drives the threaded baffle 6 to rotate synchronously, the threaded baffle 6 moves axially along the internal thread. The drum 5 moves axially during the winding and unwinding of the steel cable 7, so that the steel cable 7 is kept in a single layer and prevented from crossing and tangling. It is also easier to reflect the winding and unwinding distance of the steel cable 7 by the number of rotations of the drum 5.

[0031] The support machine includes a support body 8 and a conical top body 10. An auxiliary wheel 9 is provided at the bottom of the support body 8. The conical top body 10 is connected to a steel cable 7. A conical top is provided on the conical top body 10, and the bottom of the conical top body 10 is slidably connected to the support body 8. A groove is provided at the top of the support body 8 to fit the conical top body 10. A threaded hole is provided on the side wall of the support body 8, penetrating the groove. A fastening bolt 11 is installed in the threaded hole, which presses the conical top body 10. After the operator places the long profile into the profile slide, they first unload one side of the steel cable 7 from the drum 5. Pull out the cone-shaped top of the cone 10 and insert it into the end of the long profile. Then pull out the steel cable 7 on one side and insert it into the cone 10. Then loosen the fastening bolt 11 so that the auxiliary wheel 9 on the support body 8 naturally touches the ground. Then tighten the fastening bolt 11 to fix the cone 10 on the support body 8. When one drum 5 winds up the steel cable 7, the steel cable 7 drags the cone 10 to move. The cone 10 pushes the long profile to the other side. The drum 5 on the other side passively releases the steel cable 7. The support body 8 supports the long profile to prevent the long profile on one side from tilting and touching the ground due to excessive weight.

[0032] The calibration circuit is a Wheatstone bridge circuit. The sliding rheostat element includes a sliding plate 21 and a resistor. The resistor is axially arranged along the spline shaft 4. The sliding plate 21 is located on the side of the drum 5 away from the threaded baffle 6, and it contacts the resistor. The drum 5 moves the sliding plate 21, which slides on the resistor to change the resistance value in the calibration circuit. When the resistances of the two sliding rheostat elements are the same, that is, when the two drums 5 move the sliding plate 21 the same distance, the bridge current in the Wheatstone bridge circuit is zero. When the system detects that the bridge current is zero, the steel cables 7 on both sides are released to the same length, and the roller 14 is located at the center of the long profile. Through the calibration mechanism composed of the traction component and the Wheatstone bridge circuit, the calibration circuit and a pair of traction components work together to detect and adjust the length of the steel cables on both sides in real time, automatically positioning the center of the long profile to the welding station, realizing the rapid centering calibration of the long profile, so as to facilitate the quick docking and welding of the short profile with the long profile, without the need for manual measurement and drawing, greatly improving the calibration accuracy and efficiency, and reducing human error.

[0033] The frame also includes a back plate 2. Both the feeding mechanism and the welding mechanism are mounted on the back plate 2. The feeding mechanism includes a pair of moving modules 18, which are slidably connected to the back plate 2. The pair of moving modules 18 are symmetrically arranged. Each moving module 18 is equipped with a transfer clamping plate 19, and each transfer clamping plate 19 is equipped with several limiting wheels 20. Each limiting wheel 20 has a right-angled concave annular groove. The welding mechanism includes a rotating module 16, which is rotatably connected to the back plate 2. The rotating module 16 is located on the outer ring of the moving modules 18, and two welding machines 17 are mounted on the rotating module 16. The operator uses the control system to adjust the movement of a pair of moving modules 18. The pair of moving modules 18 drive the limit wheels 20 on both sides to move closer together through the adapter clamp 19 until the limit wheels 20 contact the short profile. The short profile slides down along the limit wheels 20 on both sides and finally falls on the long profile. After welding is completed, the pair of moving modules 18 drive the limit wheels 20 on both sides to separate and release the short profile. The operator moves the long profile through the traction component to weld more short profiles onto the long profile. The rotating module 16 drives the welding machine 17 to rotate, and the welding machine 17 performs ring welding on the four sides where the short profile and the long profile are in contact.

[0034] The working principle of this invention is as follows: The operator places the long profile to be welded into the profile slide, and then connects a pair of calibration mechanisms to the two ends of the long profile respectively. The traction component drives the long profile to move quickly, the calibration circuit quickly calibrates the center of the profile, the short profile is brought into contact with the long profile through the feeding mechanism, and the welding mechanism then welds the short profile onto the long profile.

[0035] Servo motor 3 drives spline shaft 4 to rotate, spline shaft 4 drives drum 5 to rotate. When drum 5 drives threaded baffle 6 to rotate synchronously, threaded baffle 6 moves axially along the internal thread. Drum 5 moves axially during the winding and unwinding of steel cable 7, so that steel cable 7 is kept in a single layer and prevents steel cable 7 from crossing and tangling. It is also easier to reflect the winding and unwinding distance of steel cable 7 by the number of rotations of drum 5.

[0036] After the operator places the long profile into the profile slide, they first pull the steel cable 7 from the drum 5, insert the conical top of the cone 10 into the end of the long profile, then pull out the steel cable 7 from one side and insert it into the cone 10. Then they loosen the fastening bolt 11 so that the auxiliary wheel 9 on the support body 8 naturally touches the ground, and then tighten the fastening bolt 11 to fix the cone 10 on the support body 8. When one drum 5 winds up the steel cable 7, the steel cable 7 drags the cone 10 to move, and the cone 10 pushes the long profile to the other side. The other drum 5 passively releases the steel cable 7, and the support body 8 supports the long profile to prevent it from tilting and touching the ground due to excessive weight on one side.

[0037] The drum 5 drives the sliding plate 21 to move. The sliding plate 21 slides on the resistor plate to change the resistance value in the calibration circuit. When the resistance of the two sliding resistor elements is the same, that is, when the two drums 5 drive the sliding plate 21 to move the same distance, the bridge current in the Wheatstone bridge circuit is zero. When the control system detects that the bridge current is zero, the steel cables 7 on both sides are released to the same length. The idler roller 14 is located at the center of the long profile. The calibration circuit and a pair of traction components work together to realize the rapid centering calibration of the long profile, so as to facilitate the rapid docking and welding of the short profile with the long profile.

[0038] The operator uses the control system to adjust the movement of a pair of moving modules 18. The pair of moving modules 18 drive the limit wheels 20 on both sides to move closer together through the adapter clamp 19 until the limit wheels 20 contact the short profile. The short profile slides down along the limit wheels 20 on both sides and finally falls on the long profile. After welding, the pair of moving modules 18 drive the limit wheels 20 on both sides to separate and release the short profile. The operator moves the long profile through the traction component to weld more short profiles onto the long profile. The rotating module 16 drives the welding machine 17 to rotate. The welding machine 17 performs ring welding on the perimeter where the short profile and the long profile are in contact. The feeding mechanism and the welding mechanism work together to realize the automatic feeding, positioning and perimeter welding of the short profile. The operator only needs simple control to complete multiple sets of welding, ensuring uniform welds, improving welding speed and product quality, and is suitable for batch production and rapid on-site construction needs.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
