Description

Technical Field

[0001] This utility model relates to the field of laser-guided high-precision welding positioning technology for door and window production, and in particular to a laser-guided high-precision welding positioning device for door and window production. Background Technology

[0002] Laser-guided high-precision welding positioning in door and window manufacturing utilizes a laser beam as a guiding tool. The laser emitter emits a high-energy-density, highly directional laser beam, which can form precise spots or lines in the welding work area, serving a positioning function. When welding the corners of door and window frames, the laser can accurately indicate the starting position, path, and ending position of the welding, with an accuracy that can reach the millimeter or even micrometer level.

[0003] The above-mentioned and existing technologies have the following drawbacks: When performing laser welding on doors and windows, since the laser guide is generally fixed to the surface of the welding head using a clamp, the distance and angle between the laser guide and the welding head surface need to be adjusted when welding at different positions of the doors and windows. If these parameters cannot be easily adjusted to adapt to welding at different positions of the doors and windows, it may be necessary to frequently change different clamps to fix the laser guide in order to achieve a near-suitable welding position. This process of frequently changing clamps will consume a lot of time, especially in the process of mass production of doors and windows, which will seriously affect production efficiency.

[0004] Therefore, a laser-guided high-precision welding positioning device for door and window production is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem of inconvenience in adjusting the distance and angle between the laser guide and the welding head on the welding head surface, and to propose a laser-guided high-precision welding positioning device for door and window production.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a laser-guided high-precision welding positioning device for door and window production, comprising a robotic arm and a laser guide. An adjusting arm is mounted on the surface of the robotic arm, a welding device is mounted on the surface of the adjusting arm, and a welding head is mounted on the surface of the welding device. A connecting plug is electrically connected to the surface of the laser guide, and several transmission plugs are electrically connected to the surface of the laser guide. An adjusting structure is provided on the surface of the welding head, comprising a ring. The ring is fixedly connected to the surface of the welding head. An internally threaded tube is fixedly connected to the arc surface of the ring. A threaded rod is threadedly connected to the inner wall of the internally threaded tube. A circular plate is rotatably connected to one end of the threaded rod away from the internally threaded tube. A frame is fixedly connected to one side of the laser guide. The circular plate is rotatably connected to the inner wall of the frame. A limiting plate is fixedly connected to the surface of the frame. A pin slides through the surface of the limiting plate. Several positioning holes are opened on the arc surface of the circular plate, and the size of the pin matches the size of the positioning holes.

[0007] The effect achieved by the above components is as follows: by setting the adjustment structure, it is easy to adjust the distance and angle between the laser guide and the welding head on the welding head surface. The appropriate distance and angle can ensure that the laser spot accurately indicates the welding start position, and the welding gun can closely follow this indication to perform welding, so that the weld position is highly consistent with the design requirements.

[0008] Preferably, the surface of the internally threaded tube has two guide rods that slide through it, and both guide rods are fixedly connected to the circular plate.

[0009] The effect achieved by the above components is that when the circular plate moves, it will cause the two guide rods to slide on the surface of the internally threaded tube. The internally threaded tube restricts the movement path of the guide rods, thereby restricting the movement path of the circular rods and preventing the circular plate from rotating when it moves.

[0010] Preferably, a spring is fitted onto the arc surface of the pin, and the two ends of the spring are fixedly connected to the pin and the limiting plate, respectively.

[0011] The effect achieved by the above components is that the pin is inserted into the positioning hole by means of the spring contraction force, and the spring reaches the position of the pin to limit the pin, thereby preventing the pin from falling out of the positioning hole due to shaking, and thus improving the stability of the pin inserted into the positioning hole.

[0012] Preferably, one end of the pin is fixedly connected to a rope, and the end of the rope away from the pin is fixedly connected to a handle.

[0013] The effect achieved by the above components is that the handle pulls the pin with the help of the rope, and the handle makes it easier to pull the rope, and thus easier to pull the pin.

[0014] Preferably, the surface of the laser guide is provided with a protective structure, the protective structure including a fixing rod, the fixing rod being fixedly connected to the surface of the laser guide, a plurality of protective plates being rotatably connected to the arc surface of the fixing rod, elastic ropes being fixedly connected to the surface of the protective plates, and a plurality of hooks being fixedly connected to the surface of the laser guide.

[0015] The effect achieved by the above components is that by setting up a protective structure, it is easy to use a protective plate to cover the transmission plug, thereby preventing the flying debris generated during welding from splashing into the transmission plug, and thus protecting the transmission plug.

[0016] Preferably, a sealing gasket is fixedly connected to the surface of the protective plate, and the sealing gasket is made of rubber.

[0017] The effect achieved by the above components is as follows: after the protective plate is rotated to a suitable angle, the protective plate will cause the sealing gasket to fit tightly against the surface of the transmission plug. The sealing gasket improves the airtightness of the fit between the protective plate and the transmission plug, preventing dust or welding debris from entering, and further protecting the transmission plug.

[0018] Preferably, the surface of the laser guide is provided with a groove, and a plurality of magnetic blocks are fixedly connected to the inner wall of the groove.

[0019] The effect achieved by the above components is that the protective plate will slide into the groove and be attracted to the surface of the magnetic block, and the magnetic block can effectively limit the position of the protective plate, thereby preventing the protective plate from shaking when not in use.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. In this utility model, by setting an adjustment structure, the distance and angle between the laser guide on the surface of the welding head and the welding head can be easily adjusted. The appropriate distance and angle can ensure that the laser spot accurately indicates the welding start position, and the welding gun can closely follow this indication to perform welding, so that the weld position is highly consistent with the design requirements.

[0022] 2. In this utility model, by setting a protective structure, the protective plate can be rotated. The protective plate will rotate on the surface of the fixed rod. The rotation of the protective plate will drive the sealing gasket to move closer to the transmission plug. When the protective plate rotates to a suitable angle, the protective plate will fit tightly against the surface of the transmission plug. Then, the elastic rope is pulled and hung on the surface of the hook. The hook restricts the position of the elastic rope, thereby restricting the position of the protective plate. This makes it easy to use the protective plate to cover the transmission plug and prevent the flying debris generated during welding from splashing into the transmission plug, thus protecting the transmission plug.

[0030] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0032] like Figure 1 - Figure 6As shown, this utility model provides a laser-guided high-precision welding positioning device for door and window production, including a robotic arm 1 and a laser guide 5. An adjusting arm 2 is mounted on the surface of the robotic arm 1, a welder 3 is mounted on the surface of the adjusting arm 2, and a welding head 4 is mounted on the surface of the welder 3. A connecting plug 6 is electrically connected to the surface of the laser guide 5, and several transmission plugs 7 are electrically connected to the surface of the laser guide 5. An adjusting structure 8 is provided on the surface of the welding head 4. By setting the adjusting structure 8, the distance and angle between the laser guide 5 and the welding head 4 can be easily adjusted. A suitable distance and angle ensures that the laser spot accurately indicates the welding start position, and the welding gun can closely follow this indication to perform welding, so that the weld position highly matches the design requirements. A protective structure 9 is provided on the surface of the laser guide 5. By setting the protective structure 9, it is possible to use a protective plate 92 to cover the transmission plugs 7, thereby preventing the flying debris generated during welding from splashing into the transmission plugs 7, thus protecting the transmission plugs 7.

[0033] The specific settings and functions of its adjustment structure 8 and protective structure 9 will be explained below.

[0034] like Figure 2 and Figure 3 and Figure 4As shown, the adjustment structure 8 includes a ring 801, which is fixedly connected to the surface of the welding head 4. An internally threaded tube 802 is fixedly connected to the arc surface of the ring 801. A threaded rod 803 is threadedly connected to the inner wall of the internally threaded tube 802. A circular plate 804 is rotatably connected to one end of the threaded rod 803 away from the internally threaded tube 802. A frame 805 is fixedly connected to one side of the laser guide 5. The circular plate 804 is rotatably connected to the inner wall of the frame 805. A limiting plate 806 is fixedly connected to the surface of the frame 805. A pin 807 slides through the surface of the limiting plate 806. Several positioning holes 808 are opened on the arc surface of the circular plate 804. The size of the pin 807 is adapted to the size of the positioning holes 808. Two guide rods 809 slide through the surface of the internally threaded tube 802. Both guide rods 809 are fixedly connected to the circular plate 804. When the circular plate 804 moves, it causes the two guide rods 809 to slide on the surface of the internally threaded tube 802. The internally threaded tube 802 restricts the movement path of the guide rods 809, thereby restricting the movement path of the circular plate 804 and preventing the circular plate 804 from rotating during movement. A spring 810 is fitted on the arc surface of the pin 807. The two ends of the spring 810 are fixedly connected to the pin 807 and the limiting plate 806, respectively. The pin 807 is inserted into the positioning hole 808 by the force of the spring 810's contraction. The spring 810 restricts the position of the pin 807, thereby preventing the pin 807 from falling out of the positioning hole 808 due to shaking, thus improving the stability of the pin 807 inserted into the positioning hole 808. One end of the pin 807 is fixedly connected to a rope 811, and the other end of the rope 811 away from the pin 807 is fixedly connected to a handle 812. The handle 812 will pull the pin 807 with the help of the rope 811. The handle 812 makes it easier to pull the rope 811, and thus makes it easier to pull the pin 807.

[0035] like Figure 5 and Figure 6 As shown, the protective structure 9 includes a fixing rod 91, which is fixedly connected to the surface of the laser guide 5. Several protective plates 92 are rotatably connected to the arc surface of the fixing rod 91. Elastic ropes 93 are fixedly connected to the surface of the protective plates 92, and several hooks 94 are fixedly connected to the surface of the laser guide 5. A sealing gasket 95, made of rubber, is fixedly connected to the surface of the protective plate 92. When the protective plate 92 rotates to a suitable angle, it causes the sealing gasket 95 to tightly adhere to the surface of the transmission plug 7. The sealing gasket 95 improves the airtightness of the fit between the protective plate 92 and the transmission plug 7, preventing dust or welding debris from entering and further protecting the transmission plug 7. A groove 96 is formed on the surface of the laser guide 5. Several magnetic blocks 97 are fixedly connected to the inner wall of the groove 96. The protective plate 92 slides into the groove 96 and is attracted to the surface of the magnetic blocks 97. The magnetic blocks 97 effectively limit the movement of the protective plate 92, preventing it from shaking when not in use.

[0036] The overall working principle is as follows: When it is necessary to adjust the distance between the laser guide 5 and the welding head 4, firstly, rotate the threaded rod 803. The rotation of the threaded rod 803 will cause it to move within the internal threaded tube 802 via the thread. The movement of the threaded rod 803 will cause the circular plate 804 to move away from the welding head 4. When the circular plate 804 moves, it will cause the two guide rods 809 to slide on the surface of the internal threaded tube 802. The internal threaded tube 802 will limit the movement path of the guide rods 809, thereby limiting the movement path of the circular rod, thus preventing the circular plate 804 from rotating during movement. When the circular plate 804 moves, it will cause the laser guide 5 to move away from the welding head 4 via the frame 805 until the laser guide 5 moves to the appropriate distance. Then, pull the handle. 812, the grip 812 will pull the pin 807 with the help of the rope 811. The pin 807 will move and slide within the limiting plate 806 and gradually disengage from the positioning hole 808. The movement of the pin 807 will stretch the spring 810. When the pin 807 disengages from the positioning hole 808, the spring 810 is in a stretched state. Then, the laser guide 5 will be rotated, which will drive the frame 805 to rotate on the surface of the circular plate 804. When the laser guide 5 is rotated to a suitable angle, the grip 812 will be released. The pin 807 will be inserted into the positioning hole 808 with the help of the contraction force of the spring 810. The pin 807 will limit the rotation of the frame 805, thereby limiting the rotation of the laser guide 5, thus adjusting the laser guide 5 to a suitable angle.

[0037] When protection of the transmission plug 7 is required, first rotate the protective plate 92. The protective plate 92 will rotate on the surface of the fixing rod 91. The rotation of the protective plate 92 will cause the sealing gasket 95 to move closer to the transmission plug 7. When the protective plate 92 rotates to a suitable angle, the protective plate 92 will cause the sealing gasket 95 to fit tightly against the surface of the transmission plug 7. The sealing gasket 95 improves the airtightness of the fit between the protective plate 92 and the transmission plug 7, preventing dust or welding debris from entering, thus further protecting the transmission plug 7. Then, pull the elastic rope 93 to hang it on the hook 9. On the surface of 4, the hook 94 restricts the position of the elastic cord 93, thereby restricting the position of the protective plate 92, thus protecting the transmission plug 7. Repeat the above operation to protect several transmission plugs 7. When it is necessary to connect the transmission line to the transmission plug 7, remove the elastic cord 93 from the hook 94, and then flip the protective plate 92. After the protective plate 92 is rotated to the appropriate position, the protective plate 92 will slide into the groove 96 and be attracted to the surface of the magnetic block 97. The magnetic block 97 can effectively limit the position of the protective plate 92, thereby preventing the protective plate 92 from shaking when not in use.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
