Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding assembly and panel light chassis welding equipment. Background Technology

[0002] When the base of a panel light needs to be welded, the weld points are generally located on the upper or lower side of the base. Therefore, the welding torch of the welding equipment is positioned above or below the base. During the process of placing and removing the base, the welding torch must be avoided. To address this, some welding equipment uses a translation drive mechanism to move the welding torch horizontally and a lifting drive mechanism to raise and lower it. Before placing or removing the base, the lifting drive mechanism raises the welding torch, and the translation drive mechanism moves it away from the base. Once the base is in place, the translation drive mechanism moves the welding torch closer to the base, and the lifting drive mechanism lowers it to meet the base for welding. However, because the translation and lifting mechanisms use two sets of drive devices, there is a drive delay between them. This can lead to situations where welding begins before the translation or lifting mechanism has reached the correct position, easily resulting in incomplete welds. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a welding assembly and panel light chassis welding equipment. Using a linear driver, the welding torch can approach and abut against the panel light chassis, eliminating the need for two sets of driving devices, thus eliminating driving delay and ensuring that welding is performed only after the welding torch has moved into position, avoiding incomplete welds.

[0004] The welding assembly according to the first aspect of the present invention includes:

[0005] The slide rail is set horizontally and has a limiting component at one end;

[0006] The active component is slidably mounted on the slide rail;

[0007] The driven member is slidably disposed on the slide rail, and the driven member is located between the driving member and the limiting member;

[0008] An elastic element connects the driving element and the driven element, and the elastic force of the elastic element causes the driven element to tend to move away from the driving element;

[0009] A linear actuator is connected to the driving member, and the linear actuator drives the driving member to move the driven member closer to or away from the limiting member;

[0010] The welding torch is slidably connected to the driven member.

[0011] A transmission mechanism connects the welding torch to the driving component;

[0012] The linear actuator drives the active member to resist the elastic force of the elastic member and move closer to the driven member, so that the transmission mechanism drives the welding torch to move downward.

[0013] The linear actuator and the elastic element drive the driving element and the driven element to move away from each other, so that the transmission mechanism drives the welding torch to move upward.

[0014] The welding assembly according to the embodiments of this utility model has at least the following beneficial effects: After the panel light base is placed in position, the linear actuator drives the active component to move towards the limiting component, causing the active component to drive the driven component to move towards the limiting component, causing the welding torch to move upwards towards the panel light base. After the driven component abuts against the limiting component, the linear actuator continues to drive the active component, compressing the elastic component to bring the active component closer to the driven component, thereby causing the transmission mechanism to drive the welding torch downwards. After the welding torch moves downwards and abuts against the panel light base, welding is performed. After the panel light base is welded, the linear actuator drives the active component away from the limiting component. The linear actuator continues to drive the driven component away from the driving component, while the elastic force of the elastic component still pushes the driven component away from the driving component, causing the transmission mechanism to move the welding torch upwards, causing the welding torch to detach from the panel light base. The linear actuator continues to drive the driving component away from the limiting component, and the elastic component returns to its original shape and pulls the driven component away from the limiting component, thereby causing the welding torch to leave the top of the panel light base, so as to facilitate the picking and placing of the panel light base. Therefore, by using a linear actuator, the welding torch can be brought close to and abutted against the panel light base without the need to set up two sets of driving devices, eliminating driving delay, ensuring that the welding torch is moved into place before welding, and avoiding the generation of incomplete welds.

[0015] According to some embodiments of the present invention, the transmission mechanism includes:

[0016] An active block is connected to the active component. The active block is provided with a sliding groove. With the direction of the driven component relative to the active component as the forward direction, the sliding groove gradually slopes upward from back to front.

[0017] A driven block is connected to the welding torch. The driven block is equipped with a slider, which is slidably disposed in the groove.

[0018] According to some embodiments of the present invention, the slider is cylindrical in shape, and the outer peripheral surface of the slider abuts against the inner sidewall of the groove.

[0019] According to some embodiments of the present invention, the front and rear ends of the slide are respectively provided with a front horizontal groove and a rear horizontal groove, the front horizontal groove extends forward and the rear horizontal groove extends backward.

[0022] As described in the above embodiments, there are multiple welding assemblies, and the multiple welding assemblies are disposed on the periphery of the worktable surface;

[0023] The inverter power supply provides power to all the welding components.

[0024] The panel light chassis welding equipment according to the present utility model has at least the following beneficial effects: After the panel light chassis is placed on the worktable, the linear driver drives the active component to move towards the limiting component, causing the active component to drive the driven component to move towards the limiting component, causing the welding torch to move upwards on the panel light chassis. After the driven component abuts against the limiting component, the linear driver continues to drive the active component, compressing the elastic component to make the active component approach the driven component, thereby causing the transmission mechanism to drive the welding torch downwards. After the welding torch moves downwards and abuts against the panel light chassis, welding is performed. After the panel light chassis welding is completed, the linear driver drives the active component away from the worktable. The limiting component, while the elastic force of the elastic component still pushes the driven component away from the driving component, causing the transmission mechanism to drive the welding torch upward, so that the welding torch disengages from the panel light base. The linear actuator continues to drive the driving component away from the limiting component, and the elastic component returns to its original shape and pulls the driven component away from the limiting component, thereby causing the welding torch to leave the top of the panel light base, so that the panel light base can be picked up and placed above the worktable. Therefore, by using a linear actuator, the welding torch can be brought close to and abutted against the panel light base without the need for two sets of drive devices, eliminating drive delay and ensuring that the welding torch is moved into place before welding, thus avoiding the generation of incomplete welds.

[0025] Setting up an inverter power supply to simultaneously power multiple welding components helps to simultaneously weld multiple positions on the panel light chassis, thus improving welding efficiency.

[0050] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0051] Reference Figure 1 As shown, the welding assembly of this utility model is implemented in the following embodiments.

[0052] The welding assembly includes a slide rail 100, a driving component 200, a driven component 300, an elastic component 400, a linear actuator 500, a welding torch 600, and a transmission mechanism 700.

[0053] The slide rail 100 extends in the front-to-back direction, and a limiting member 110 is provided at the front end of the slide rail 100.

[0054] Both the driving member 200 and the driven member 300 are mounted on the slide rail 100. The driving member 200 and the driven member 300 slide back and forth along the slide rail 100, with the driven member 300 located in front of the driving member 200.

[0055] The front end of the elastic element 400 is connected to the driven element 300 and the rear end is connected to the driving element 200. When the elastic element 400 is compressed, it has an elastic force that pushes the driving element 200 and the driven element 300 away from each other.

[0056] The linear actuator 500 is mounted on the slide rail 100, or it can be fixed to the side of the slide rail 100. The linear actuator 500 is connected to the driving member 200 and drives the driving member 200 to move in the back-and-forth direction.

[0057] When the linear actuator 500 drives the driving member 200 to move forward, the elastic member 400 is compressed and pushes the driven member 300 to move forward, so that the driven member 300 moves closer to the limiting member 110.

[0058] When the linear actuator 500 drives the driving member 200 to move backward, the elastic member 400 pulls the driven member 300 to move backward, causing the driven member 300 to move away from the limiting member 110.

[0059] The welding torch 600 is slidably connected to the driven member 300, and the welding torch 600 slides in the up-down direction.

[0060] The transmission mechanism 700 is connected to the welding torch 600 and the driving member 200 respectively. The transmission mechanism 700 converts the back-and-forth movement of the driving member 200 relative to the welding torch 600 into the up-and-down movement of the welding torch 600.

[0061] After the linear actuator 500 drives the driving member 200 to move forward, the elastic member 400 is compressed and pushes the driven member 300 to move forward and abut against the limiting member 110, thereby fixing the position of the driven member 300. The linear actuator 500 continues to drive the driving member 200 to move forward, so that the driving member 200 moves forward relative to the welding torch 600 on the driven member 300. The transmission mechanism 700 converts the forward movement of the driving member 200 relative to the welding torch 600 into the downward movement of the welding torch 600.

[0062] After the linear actuator 500 drives the driving member 200 to move backward, as the elastic member 400 gradually returns to its original state, the position of the driven member 300 remains fixed, while the linear actuator 500 continues to drive the driving member 200 to move backward, causing the driving member 200 to move backward relative to the welding torch 600 on the driven member 300. The transmission mechanism 700 converts the backward movement of the driving member 200 relative to the welding torch 600 into the upward movement of the welding torch 600.

[0063] After the panel light base is placed in place, the linear actuator 500 drives the active component 200 to move towards the limiting component 110, causing the elastic component 400 to push the driven component 300 to move towards the limiting component 110, causing the welding torch 600 to move upwards towards the panel light base. After the driven component 300 abuts against the limiting component 110, the position of the driven component 300 remains unchanged. The linear actuator 500 continues to drive the active component 200, compressing the elastic component 400 to bring the active component 200 closer to the driven component 300, thereby causing the transmission mechanism 700 to drive the welding torch 600 downwards. After the welding torch 600 moves downwards and abuts against the panel light base, welding is performed.

[0064] After the panel light chassis is welded, the linear actuator 500 drives the active component 200 away from the limiting component 110, while the elastic force of the elastic component 400 still pushes the driven component 300 away from the active component 200, causing the transmission mechanism 700 to drive the welding torch 600 to move upward, causing the welding torch 600 to detach from the panel light chassis upward. The linear actuator 500 continues to drive the active component 200 away from the limiting component 110, and the elastic component 400 returns to its original shape and pulls the driven component 300 to detach from the limiting component 110, thereby causing the welding torch 600 to leave the top of the panel light chassis, so as to facilitate the removal and placement of the panel light chassis.

[0065] Therefore, by using a linear driver 500, the welding torch 600 can approach and abut against the panel light chassis without the need for two sets of driving devices, thus eliminating driving delay and ensuring that the welding torch 600 moves into place before welding, avoiding the occurrence of cold welds.

[0066] There are various forms of transmission mechanism 700.

[0067] For example, the transmission mechanism 700 includes a connecting rod, with the rear end of the connecting rod hinged to the driving member 200 and the front end of the connecting rod hinged to the welding torch 600. The rear end of the connecting rod is higher than the front end. Since the degree of freedom of the driven member 300 to move forward is restricted by the limiting member 110, the welding torch 600 is fixed and can only move in the up and down direction. When the driving member 200 gradually approaches the welding torch 600, since the length of the connecting rod is fixed and the height of the rear end of the connecting rod is fixed, the front end of the connecting rod can only rotate downward, thereby driving the welding torch 600 to move downward. When the driving member 200 is driven by the linear actuator 500 and the elastic member 400 and gradually moves away from the driven member 300, that is, the driving member 200 gradually moves away from the welding torch 600, since the length of the connecting rod is fixed and the height of the rear end of the connecting rod is fixed, the front end of the connecting rod can only move upward, thereby driving the welding torch 600 to move upward.

[0068] Alternatively, the transmission mechanism 700 includes a driving rack, a gear, and a driven rack. The driving rack is mounted on the driving member 200 and extends in the front-to-back direction. The gear is mounted on the driven member 300 and meshes with the gear. The driven rack is mounted on the welding torch 600 and meshes with the gear. The driven rack extends in the vertical direction. As the driving member 200 moves forward relative to the driven member 300, the driving rack drives the gear to rotate clockwise, and the gear drives the driven rack to move downward, causing the welding torch 600 to move downward. As the driving member 200 moves backward relative to the driven member 300, the driving rack drives the gear to rotate counterclockwise, and the gear drives the driven rack to move upward, causing the welding torch 600 to move upward.

[0069] Alternatively, the transmission mechanism 700 includes a drive screw, a threaded sleeve, an external gear, and a rack. The drive screw is connected to the drive member 200 and extends in the front-to-back direction. The threaded sleeve is rotatably fitted around the outside of the screw and rotates around the axis extending in the front-to-back direction. The threaded sleeve is rotatably connected to the driven member 300. The external gear is fitted around the outside of the threaded sleeve and rotates synchronously with the threaded sleeve. The rack is connected to the welding torch 600 and extends in the vertical direction. The external gear meshes with the rack. As the drive member 200 moves forward relative to the driven member 300, the drive screw causes the threaded sleeve to drive the external gear to rotate in the forward direction. The external gear drives the rack to move the welding torch 600 downward. As the drive member 200 moves backward relative to the driven member 300, the drive screw causes the threaded sleeve to drive the external gear to rotate in the reverse direction. The external gear drives the rack to move the welding torch 600 upward.

[0070] In some embodiments, refer to Figure 1As shown, the transmission mechanism 700 includes a driving block 710 and a driven block 720. The driving block 710 is connected to the front end of the driving member 200. The left or right side wall of the driving block 710 is provided with a sliding groove 711 that runs through the left and right sides. The sliding groove 711 gradually slopes downward from front to back. The driven block 720 is connected to the rear side of the welding torch 600. The driven block 720 is provided with a slider 721. The slider 721 is disposed in the sliding groove 711 and slides along the sliding groove 711.

[0071] The driven member 300 abuts against the limiting member 110 and remains stationary. When the driving member 200 gradually approaches the driven member 300, the slide groove 711 of the driving block 710 guides the slider 721. The slide groove 711 gradually tilts downward from front to back. Since the welding torch 600 only moves up and down relative to the driven member 300, the slider 721 moves downward along the slide groove 711, causing the welding torch 600 to move downward accordingly.

[0072] The transmission mechanism 700 has a simple structure and is easy to assemble, making its transmission action more reliable. The mechanical structure makes the up-and-down and back-and-forth movements of the welding torch 600 more precise and accurate.

[0073] In some embodiments, refer to Figure 1 As shown, the slider 721 is cylindrical, and the outer peripheral surface of the slider 721 abuts against the inner sidewall of the groove 711.

[0074] By using a cylindrical slider 721 to slide in a groove 711, the mutual wear between the slider 721 and the groove 711 is reduced, making the slider 721 slide more smoothly.

[0075] In some embodiments, refer to Figure 1 As shown, the front end of the slide groove 711 is provided with a forward-extending front horizontal groove 712, and the rear end of the slide groove 711 is provided with a rearward-extending rear horizontal groove 713.

[0076] When the active component 200 moves backward relative to the welding torch 600, the slider 721 moves upward to the front end of the slide groove 711 and falls into the front horizontal groove 712. This allows for positioning of the height of the slider 721, preventing it from sliding down the slide groove 711 due to gravity and ensuring accurate positioning of the slider 721 after it moves upward. When the active component 200 moves forward relative to the welding torch 600, the slider 721 moves downward to the rear end of the slide groove 711 and falls into the rear horizontal groove 713. This allows for positioning of the height of the slider 721, preventing the welding torch 600 from wobbling upward after it moves downward. This ensures that the welding torch 600 can press firmly against the panel light base after it moves downward, preventing incomplete welding caused by the rebound of the panel light base.

[0077] Reference Figures 2 to 5 As shown, the panel light chassis welding equipment of this utility model is implemented in the following embodiments.

[0078] Reference Figure 2 and Figure 3 As shown, the panel light chassis welding equipment includes a worktable 800 and multiple welding components 810. The multiple welding components 810 are respectively arranged on the periphery of the four corners of the worktable 800, so that the welding components 810 can weld the four corners of the panel light chassis to form the panel light chassis.

[0079] Setting up an inverter power supply to simultaneously power multiple welding components 810 helps the multiple welding components 810 to simultaneously weld multiple positions on the panel light chassis, thereby improving welding efficiency.

[0080] After the panel light base is placed on the worktable 800, the linear actuator 500 drives the active component 200 to move towards the limiting component 110, causing the elastic component 400 to push the driven component 300 to move towards the limiting component 110, causing the welding torch 600 to move above the corner of the panel light base. After the driven component 300 abuts against the limiting component 110, the position of the driven component 300 remains unchanged. The linear actuator 500 continues to drive the active component 200, compressing the elastic component 400 to bring the active component 200 closer to the driven component 300, thereby causing the transmission mechanism 700 to drive the welding torch 600 to move downward. After the welding torch 600 moves downward and abuts against the corner of the panel light base, welding is performed.

[0081] After the corner welding of the panel light chassis is completed, the linear actuator 500 drives the active component 200 away from the limiting component 110, while the elastic force of the elastic component 400 still pushes the driven component 300 away from the active component 200, causing the transmission mechanism 700 to drive the welding torch 600 to move upward, causing the welding torch 600 to disengage from the corner of the panel light chassis upward. The linear actuator 500 continues to drive the active component 200 away from the limiting component 110, and the elastic component 400 returns to its original shape and pulls the driven component 300 away from the limiting component 110, thereby causing the welding torch 600 to leave the top of the panel light chassis, so as to facilitate the removal and placement of the panel light chassis.

[0082] Therefore, by using a linear driver 500, the welding torch 600 can approach and abut against the corner of the panel light chassis without the need for two sets of driving devices, thus eliminating driving delay and ensuring that the welding torch 600 moves into place before welding, avoiding the occurrence of cold welds.

[0083] In some embodiments, refer to Figure 2 and Figure 3 As shown, the panel light chassis welding equipment also includes a feeding mechanism 820 and a transfer mechanism 830.

[0084] The feeding mechanism 820 is located on the front side of the worktable, and the transfer mechanism 830 is located on the left or right side of the worktable 800. The feeding mechanism 820 transports the workpiece 900 to be welded from front to back to the front of the worktable 800. The transfer mechanism 830 takes the workpiece 900 to be welded from the rear end of the feeding mechanism 820 and moves it above the worktable 800. Then, the workpiece 900 to be welded is placed on the worktable 800 from top to bottom. Multiple welding components 810 weld the edges and corners of the workpiece 900 to form a welded workpiece 910. After the welding components 810 move away from the welded workpiece 910, the transfer mechanism 830 takes the welded workpiece 910 up from the worktable 800.

[0085] With the cooperation of the transfer mechanism 830 and the feeding mechanism 820, the transfer mechanism 830 picks up and puts the panel light base of the worktable 800 in the up and down direction, and the welding component 810 can avoid the panel light base and ensure that the welding component 810 is in close contact with the panel light base during the welding process.

[0086] In some embodiments, refer to Figure 2 and Figure 3 As shown, the transfer mechanism 830 includes a first clamping member 831 and a second clamping member 832 arranged at intervals. The distance from the rear end of the feeding mechanism 820 to the worktable 800 is equal to the distance from the first clamping member 831 to the second clamping member 832.

[0087] The first clamping member 831 picks up the workpiece 900 to be welded at the rear end of the feeding mechanism 820, while the second clamping member 832 picks up the welded workpiece 910 on the worktable 800.

[0088] The first clamping member 831 places the workpiece 900 to be welded on the worktable 800, while the second clamping member 832 transfers the welded workpiece 910 to the next process.

[0089] Setting up a first clamping member 831 and a second clamping member 832 to pick up and place the workpiece 900 to be welded and the workpiece 910 already welded, respectively, helps to improve workpiece transfer efficiency and thus improve production efficiency.

[0090] In some embodiments, refer to Figure 2 and Figure 3 As shown, the panel light chassis welding equipment also includes a feeding mechanism 840 and a flipping mechanism 850. The feeding mechanism 840 and the flipping mechanism 850 are located behind the worktable 800. The feeding mechanism 840 transports the welded workpiece 910 from front to back. The flipping mechanism 850 is located above the front end of the feeding mechanism 840. The transfer mechanism 830 places the welded workpiece 910 onto the flipping mechanism 850. The flipping mechanism 850 flips the upper and lower sides of the welded workpiece 910 and then places it back onto the front end of the feeding mechanism 840.

[0091] The flipping mechanism 850 flips the welded panel light base, and then the unloading mechanism 840 transports the flipped panel light base to the next process, thereby saving the time required for the subsequent flipping action and improving production efficiency.

[0092] In some embodiments, refer to Figures 2 to 4 As shown, the panel light chassis welding equipment also includes multiple tilting welders 860, which are respectively arranged on the four corners of the worktable 800. Each tilting welder 860 includes a track 861, a welding head 862, and a driver 863.

[0093] The track 861 is installed on the periphery of the workbench 800. The track 861 has a first end and a second end. The first end is close to the workbench 800, and the second end is away from the workbench 800. The track 861 gradually slopes upward from the first end to the second end. The welding head 862 is slidably connected to the track 861. The welding head 862 slides along the track. When the welding head 862 moves towards the first end, it gradually moves downward towards the base of the panel light. When the welding head 862 moves towards the second end, it gradually moves upward away from the base of the panel light. The driver 863 is set on the track 861. The driver 863 is connected to the welding head 862 and drives the welding head 862 to move.

[0094] As the welding head 862 moves towards the first end, it gradually moves downwards towards the base of the panel light, enabling the welding head 862 to weld the corners of the base of the panel light. As the welding head 862 moves towards the second end, it gradually moves upwards away from the base of the panel light, ensuring that the welding head 862 moves upwards and outwards away from the base of the panel light, thus avoiding obstructing the removal and placement of the base of the panel light.

[0095] In some embodiments, refer to Figure 2 , Figure 3 and Figure 5 As shown, the panel light chassis welding equipment also includes multiple clamping assemblies 870, which are arranged around the worktable 800. Each clamping assembly 870 includes a linear rotary driver 871 and a clamping block 872.

[0096] The linear rotary actuator 871 includes a linear push rod, a movable rod, and a rotary track. The rotary track is mounted on the linear push rod and has a through hole running vertically through the rod. The inner wall of the through hole has a track groove that extends vertically in a spiral shape around the vertical axis. The movable rod is rotatably connected to the linear push rod. The outer wall of the movable rod has a guide post that cooperates with the track groove. The linear push rod pushes the movable rod to move up and down, causing the guide post to move along the track groove, thereby causing the movable rod to rotate around the vertical axis.

[0097] The clamp 872 is connected to the linear rotary driver 871, which drives the clamp 872 to move in the up and down direction and rotate around the vertical axis.

[0098] The clamping block 872 moves downward and rotates in the forward direction, so that the clamping block 872 rotates above the panel light base and gradually presses the panel light base downward to prevent the panel light base from loosening during the welding process and affecting the welding effect; the clamping block 872 moves upward and rotates in the reverse direction, so that the clamping block 872 moves upward away from the panel light base and gradually offsets from the panel light base, so that the clamping block 872 does not obstruct the panel light base picking and placing action on the worktable 800.

However, the present utility model is not limited to the above embodiments. Within the knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
