Description

Technical Field

[0001] The invention belongs to the technical field of lamp welding, and in particular relates to a welding device and a welding method for lamp processing. Background Art

[0002] Lamp processing and welding is an important part of the lamp manufacturing process, which involves a variety of welding technologies and methods to ensure that the lamp has a stable structure, reliable electrical connection and beautiful appearance. Conventional lamps mainly include lamps, among which round lamps are often used in various occasions due to their wide adaptability. When processing round lamps, it is often necessary to process and weld the sides of the round lamps, that is, to weld the sides of the lamp shell. At this time, a special welding device is needed to weld them.

[0003] Conventional welding devices mainly consist of two parts: a clamping assembly and a welding assembly. When in use, the lamp is first clamped by the clamping assembly, and then welded by the welding assembly. The above process first requires the lamp to be clamped and positioned, and the welding assembly needs to be positioned after welding is completed, that is, at least two positioning processes are required to weld the lamp, and the overall welding efficiency is low.

[0004] At the same time, when performing welding processing on the lamp, that is, welding the side of the lamp, due to the existence of the clamping assembly, the welding assembly needs to be welded at the clamping position. Due to the setting of the welding assembly, it causes a certain interference with the welding assembly. In the prior art, it is necessary to loosen the clamping assembly and then rotate the workpiece and clamp it again before welding can be performed on the original clamping position. The overall welding time is relatively long, which seriously affects the overall welding efficiency. Summary of the invention

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

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a welding device for lamp processing, comprising a frame, a mounting frame is fixedly installed on the top of the frame, a motor is fixedly installed inside the mounting frame, a base is fixedly installed on the inner side surface of the frame near the bottom end, a limiting guide rail is fixedly installed at an equal angle on the top end of the base, a lower movable plate is provided in the middle of the bottom end of the base, a cylinder is fixedly installed in the middle of the bottom end of the base, the output end of the cylinder is connected to the middle of the top end of the lower movable plate, an adjustment component is fixedly installed on the top end of the lower movable plate near the outer side surface, and the top of the adjustment component A locking frame is fixedly installed on both ends, and the locking frame is movably connected with the limiting guide rail. A circular guide rail is fixedly installed on the side of the top of the locking frame away from the cylinder, and a clamping assembly is fixedly installed on the side of the top of the locking frame close to the cylinder. A self-locking telescopic rod is fixedly installed on the output end of the motor, and an upper movable plate is fixedly installed on the bottom end of the self-locking telescopic rod, and a linkage assembly is installed on the side of the bottom end of the upper movable plate close to the outer side surface, and a welding assembly is fixedly installed on the bottom end of the linkage assembly, and one end of the welding assembly away from the upper movable plate is movably connected with the circular guide rail, and the bottom end of the welding assembly is in contact with the top of the clamping assembly.

[0007] Before welding the lamp, the round lamp can be placed between a plurality of clamping components, that is, above the base, while the device is restored to its initial position, and the welding component is connected to an external welding protective atmosphere to complete the preparation work before welding.

[0008] As a further technical solution of the present invention, the adjustment assembly includes a third fixed seat, the bottom end of the third fixed seat is connected to the top of the lower movable plate at a position close to the outer side surface, the end of the third fixed seat away from the lower movable plate is movably connected to the second connecting rod via a rotating shaft, the end of the second connecting rod away from the third fixed seat is movably connected to the fourth fixed seat via a rotating shaft, and the top end of the fourth fixed seat is fixedly connected to the bottom end of the locking frame.

[0009] When clamping and fixing the circular lamp, the cylinder can be opened and its extension can be controlled. At this time, the lower movable plate moves downward and pulls the third fixed seat downward. At this time, the second connecting rod deflects toward the middle and drives the fourth fixed seat to move toward the middle of the cylinder. At this time, the locking frame moves relative to the limit guide rail and drives multiple locking frames to move relatively close. At this time, multiple clamping components move toward the middle of the lower movable plate until they contact the outer side of the lamp, completing the clamping and fixing process.

[0010] As a further technical solution of the present invention, the linkage assembly includes a mounting block, the bottom end of the mounting block is connected to the top end of the welding assembly, the top end of the mounting block is fixedly installed with a first fixed seat, and the end of the first fixed seat away from the mounting block is movably connected to a first connecting rod through a rotating shaft.

[0011] As a further technical solution of the present invention, one end of the first connecting rod away from the first fixing seat is movably connected to the second fixing seat via a rotating shaft, and the top end of the second fixing seat is connected to the bottom end of the upper movable plate at a position close to the outer side surface.

[0012] When the lamp is clamped and fixed, since the multiple locking frames are relatively close to each other, the multiple annular guide rails can be driven relatively close to each other synchronously. At this time, the welding assembly at the top of the annular guide rail will be displaced accordingly, that is, the welding assembly will move toward the middle of the lower movable plate, and the mounting block and the first fixed seat will move toward the middle of the lower movable plate. At this time, the self-locking telescopic rod needs to be kept in an unlocked state, that is, the first connecting rod is deflected toward the middle and an upward thrust is applied to the first fixed seat. At this time, the upper movable plate rises accordingly, and the self-locking telescopic rod is compressed accordingly. After the clamping of the lamp is completed, the self-locking telescopic rod can be operated to keep it in a locked state.

[0013] As a further technical solution of the present invention, the welding assembly includes a fixed frame, a ring-shaped guide block is fixedly installed on the bottom end of the fixed frame, the ring-shaped guide block is movably connected to the ring-shaped guide rail, the ring-shaped guide block rotates relative to the ring-shaped guide rail, and the top end of the fixed frame is connected to the bottom end of the mounting block.

[0014] As a further technical solution of the present invention, a welding machine is fixedly installed on the top of the fixed frame, a welding head is fixedly installed on the output end of the welding machine, the welding end of the welding head passes through one side of the mounting block, and an active guide ball located above the clamping assembly is fixedly installed on the bottom end of the fixed frame.

[0015] When the linkage assembly follows the adjustment assembly to complete the adjustment synchronously, since the annular guide rail and the annular guide block remain in a clamping state, when the annular guide rail moves toward the middle of the lower movable plate, the annular guide block then approaches the middle of the lower movable plate, and drives the fixing frame and the welding machine to approach the middle of the lower movable plate. At this time, the welding head then approaches the middle of the lower movable plate. After the clamping and fixation of the lamp is completed, the welding head is synchronously adjusted to the welding position, completing the synchronous adjustment of the welding positioning.

[0016] By utilizing the welding and fixing process of the lamp, that is, through the clamping process and utilizing the cooperation of the linkage assembly and the welding assembly, after the device completes the clamping and fixing of the lamp, the positioning process of the welding position can be completed simultaneously. The whole process is completed automatically, and there is no need for at least two positioning processes required by traditional devices. This effectively shortens the welding time, simplifies the operating steps, and improves the overall welding efficiency.

[0017] At the same time, when the welding positioning of the lamp is completed, the motor can be turned on, and the self-locking telescopic rod at the bottom can be driven to rotate. At this time, the upper movable plate at the bottom rotates synchronously, and at the same time drives the linkage assembly and the welding assembly at the bottom to rotate circumferentially. At this time, the annular guide block can be clamped between multiple annular guide rails and rotate along the circular path formed by the multiple annular guide rails, that is, the outer side of the lamp is circularly welded with the lamp as a circle, completing the entire welding process.

[0018] Through the coordination between the welding assembly and the annular guide rail, and through the coordination between the linkage assembly and the upper movable plate, after the device completes the welding positioning, the circumferential welding process can be automatically completed by rotating the upper movable plate. The entire process does not require the workpiece to be rotated, and circumferential welding can be performed quickly while maintaining the welding positioning. The welding process on the outer side of the lamp can be completed quickly, shortening the welding time and further improving the welding efficiency.

[0019] As a further technical solution of the present invention, the clamping assembly includes a longitudinal guide rail, the bottom end of the longitudinal guide rail is connected to the top end of the locking frame, the internal movable clamp of the longitudinal guide rail is provided with a longitudinal guide block, the bottom end of the longitudinal guide block is fixedly installed with a limit spring located inside the longitudinal guide rail, and the bottom end of the limit spring is connected to the bottom end of the inner cavity of the longitudinal guide rail.

[0020] As a further technical solution of the present invention, a fixed guide ball is fixedly installed on the top of the longitudinal guide block, and a clamping block is fixedly installed on one side of the longitudinal guide block close to the cylinder.

[0021] As a further technical solution of the present invention, when the top end of the fixed guide ball contacts the bottom end of the active guide ball, the limit spring is compressed to the limit state and the clamp is at the lowest point; when the fixed guide ball is not in contact with the active guide ball, the limit spring is in the initial state and the clamp is at the highest point.

[0022] During circumferential welding, when the welding assembly moves to the top of any clamping assembly, the active guide ball contacts the fixed guide ball, and the active guide ball applies a downward thrust to the fixed guide ball. The limit spring is compressed accordingly, and at the same time drives the fixed guide ball and the clamp block to move downward until the clamp block moves to the bottom of the lamp. At this time, the clamp block at the corresponding position no longer contacts the lamp, and the clamp is temporarily released to avoid welding interference. When the welding assembly no longer contacts the corresponding clamping assembly, the limit spring can automatically reset and drive the clamp block to automatically rise, reset and clamp again, completing the automatic avoidance of clamping interference process.

[0023] Through the coordination between the clamping assembly and the welding assembly, that is, when the welding assembly rotates along the circumference of the lamp, it can automatically move to the clamping assembly, and cooperate with the action of the clamping assembly to automatically release the clamping fixation of the clamp block. The whole process is completed automatically. When the welding assembly reaches the clamping point, the clamping of the corresponding point can be temporarily released, and after the welding is completed at the corresponding point, the clamping process is automatically resumed, which effectively avoids welding interference at the clamping position, simplifies the operation steps, and improves the welding quality.

[0024] A welding method for a welding device for lamp processing, comprising the following steps:

[0025] S1: When welding the lamp, the lamp can be placed between the four clamping components, and the cylinder is turned on to control the cylinder to extend. At this time, the lower movable plate is lowered, and the second connecting rod is pulled to deflect toward the middle. At this time, the multiple locking frames can be pulled relatively close until the multiple clamping components are relatively close to clamp and fix the lamp in the middle;

[0026] S2: When the lamp is clamped and fixed, the annular guide block can follow the displacement of the annular guide rail, and the self-locking telescopic rod can be kept in a telescopic state. At this time, the first connecting rod deflects toward the middle and drives the upper movable plate to move upward. When the clamping and fixing are completed, the self-locking telescopic rod can be kept in a locked state, and the welding assembly can be synchronously adjusted to the welding position following the clamping assembly;

[0027] S3: At this time, the welding machine can be turned on and the side of the shell can be welded through the welding head, and the motor can be turned on to drive the upper movable plate at the bottom to rotate, and drive the linkage assembly and welding assembly at the bottom to rotate circumferentially. At this time, the welding assembly can perform circumferential welding on the lamp;

[0028] S4: At the same time, when the active guide ball moves to the top of any fixed guide ball, the fixed guide ball is pressurized and drives the longitudinal guide block to move downward. At this time, the limit spring is compressed and drives the clamping block to move downward at the same time. At this time, the clamping at the corresponding position is contacted to avoid welding interference until the welding assembly is no longer located above the clamping assembly. At this time, the clamping block automatically moves up to continue to complete the clamping of the corresponding point.

[0029] The beneficial effects of the present invention are as follows:

[0030] (1) The present invention utilizes the welding and fixing process of the lamp, that is, through the clamping process and the cooperation of the linkage assembly and the welding assembly, so that after the device completes the clamping and fixing of the lamp, the positioning process of the welding position can be completed simultaneously. The whole process is completed automatically, and there is no need for at least two positioning processes required by traditional devices. The welding time is effectively shortened, the operation steps are simplified, and the overall welding efficiency is improved.

[0031] (2) The present invention achieves coordination between the welding assembly and the annular guide rail, and coordination between the linkage assembly and the upper movable plate, so that after the device completes the welding positioning, the circumferential welding process can be automatically completed by rotating the upper movable plate. The workpiece does not need to be rotated during the entire process, and circumferential welding can be performed quickly while maintaining the welding positioning. The welding process of the outer side of the lamp can be completed quickly, shortening the welding time and further improving the welding efficiency.

[0032] (3) The present invention achieves a coordinated effect between the clamping assembly and the welding assembly, that is, when the welding assembly rotates along the circumference of the lamp, it can automatically move to the clamping assembly and automatically release the clamping fixation of the clamp block by cooperating with the action of the clamping assembly. The whole process is completed automatically. When the welding assembly reaches the clamping point, the clamping of the corresponding point can be temporarily released, and after the welding is completed at the corresponding point, the clamping process is automatically resumed, thereby effectively avoiding welding interference at the clamping position, simplifying the operating steps, and improving the welding quality.

[0045] Before welding the lamp, the circular lamp can be placed between multiple clamping components 15, that is, above the base 8, and the device can be restored to its original position, and the welding component 7 can be connected to the external welding protective atmosphere to complete the preparation work before welding.

[0046] like Figure 1 and Figure 6 as well as Figure 7 and Figure 8 As shown, the adjustment assembly 12 includes a third fixed seat 121, the bottom end of the third fixed seat 121 is connected to the top of the lower movable plate 10 at a position close to the outer side surface, the end of the third fixed seat 121 away from the lower movable plate 10 is movably connected to the second connecting rod 123 through a rotating shaft, the end of the second connecting rod 123 away from the third fixed seat 121 is movably connected to the fourth fixed seat 122 through a rotating shaft, and the top end of the fourth fixed seat 122 is fixedly connected to the bottom end of the locking frame 13.

[0047] When clamping and fixing the circular lamp, the cylinder 11 can be turned on and its extension can be controlled.

At this time, the second connecting rod 123 deflects toward the middle and drives the fourth fixed seat 122 to move toward the middle of the cylinder 11.

At this time, multiple clamping assemblies 15 move toward the middle of the lower movable plate 10 until they contact the outer side of the lamp, completing the clamping and fixing process.

[0048] like Figure 1 and Figure 3 as well as Figure 4 As shown, the linkage assembly 6 includes a mounting block 601, the bottom end of the mounting block 601 is connected to the top end of the welding assembly 7, a first fixing seat 602 is fixedly installed on the top end of the mounting block 601, one end of the first fixing seat 602 away from the mounting block 601 is movably connected to a first connecting rod 604 via a rotating shaft, one end of the first connecting rod 604 away from the first fixing seat 602 is movably connected to a second fixing seat 603 via a rotating shaft, and the top end of the second fixing seat 603 is connected to the bottom end of the upper movable plate 5 at a position close to the outer side surface.

[0049] When the lamp is clamped and fixed, since the multiple locking frames 13 are relatively close to each other, the multiple annular guide rails 14 can be driven to be relatively close to each other synchronously. At this time, the welding assembly 7 located at the top of the annular guide rail 14 will be displaced accordingly, that is, the welding assembly 7 will move toward the middle of the lower movable plate 10. At this time, the mounting block 601 and the first fixed seat 602 will move toward the middle of the lower movable plate 10. At this time, the self-locking telescopic rod 4 needs to be kept in an unlocked state, that is, the first connecting rod 604 is deflected toward the middle, and an upward thrust is applied to the first fixed seat 602. At this time, the upper movable plate 5 rises accordingly, and the self-locking telescopic rod 4 is compressed accordingly. After the clamping of the lamp is completed, the self-locking telescopic rod 4 can be operated to remain in a locked state.

[0050] like Figure 1 and Figure 3 as well as Figure 5 As shown, the welding assembly 7 includes a fixed frame 701, a ring-shaped guide block 702 is fixedly installed at the bottom end of the fixed frame 701, the ring-shaped guide block 702 is movably connected with the ring-shaped guide rail 14, the ring-shaped guide block 702 rotates relative to the ring-shaped guide rail 14, the top of the fixed frame 701 is connected to the bottom end of the mounting block 601, a welding machine 703 is fixedly installed at the top end of the fixed frame 701, a welding head 704 is fixedly installed at the output end of the welding machine 703, the welding end of the welding head 704 passes through one side of the mounting block 601, and an active guide ball 705 located above the clamping assembly 15 is fixedly installed at the bottom end of the fixed frame 701.

At this time, the welding head 704 then approaches the middle of the lower movable plate 10. After the clamping and fixing of the lamp is completed, the welding head 704 is synchronously adjusted to the welding position, completing the synchronous adjustment of the welding positioning.

[0052] By utilizing the welding and fixing process of the lamp, that is, through the clamping process and utilizing the cooperation of the linkage component 6 and the welding component 7, after the device completes the clamping and fixing of the lamp, the positioning process of the welding position can be completed simultaneously. The whole process is completed automatically, and there is no need for at least two positioning processes required by traditional devices. The welding time is effectively shortened, the operating steps are simplified, and the overall welding efficiency is improved.

[0053] At the same time, when the welding positioning of the lamp is completed, the motor 3 can be turned on, and the self-locking telescopic rod 4 at the bottom can be driven to rotate. At this time, the upper movable plate 5 at the bottom rotates synchronously, and at the same time drives the linkage assembly 6 and the welding assembly 7 at the bottom to rotate circumferentially. At this time, the annular guide block 702 can be clamped between the multiple annular guide rails 14 and rotate along the circular path formed by the multiple annular guide rails 14, that is, the outer side of the lamp is circularly welded with the lamp as a circle, completing the entire welding process.

[0054] Through the coordination between the welding assembly 7 and the annular guide rail 14, and through the coordination between the linkage assembly 6 and the upper movable plate 5, after completing the welding positioning, the device can automatically complete the circumferential welding process by rotating the upper movable plate 5. The whole process does not require the workpiece to be rotated, and circumferential welding can be performed quickly while maintaining the welding positioning. The welding process of the outer side of the lamp can be completed quickly, shortening the welding time and further improving the welding efficiency.

[0056] Embodiment: When performing circumferential welding, when the welding component 7 moves to the top of any clamping component 15, the active guide ball 705 is in contact with the fixed guide ball 154, and the active guide ball 705 applies a downward thrust to the fixed guide ball 154. At this time, the limit spring 153 is compressed, and at the same time drives the fixed guide ball 154 and the clamping block 155 to move downward until the clamping block 155 moves to the bottom of the lamp. At this time, the clamping block 155 at the corresponding position is no longer in contact with the lamp, and the clamping is temporarily released to avoid welding interference. When the welding component 7 is no longer in contact with the corresponding clamping component 15, the limit spring 153 can be automatically reset, and drive the clamping block 155 to automatically rise, reset and clamp again, and complete the automatic avoidance of clamping interference process.

[0057] Through the cooperation between the clamping component 15 and the welding component 7, that is, when the welding component 7 rotates along the circumference of the lamp, it can automatically move to the clamping component 15, and cooperate with the action of the clamping component 15 to automatically release the clamping fixation of the clamping block 155. The whole process is completed automatically. When the welding component 7 reaches the clamping point, the clamping of the corresponding point can be temporarily released, and after the welding is completed at the corresponding point, the clamping process is automatically restored, which effectively avoids welding interference at the clamping position, simplifies the operating steps, and improves the welding quality.

[0059] S1: When welding the lamp, the lamp can be placed between the four clamping assemblies 15, and the cylinder 11 is turned on to control the extension of the cylinder 11. At this time, the lower movable plate 10 is lowered, and the second connecting rod 123 is pulled to deflect toward the middle. At this time, the multiple locking frames 13 can be pulled relatively close until the multiple clamping assemblies 15 are relatively close to clamp and fix the lamp in the middle;

[0060] S2: When the lamp is clamped and fixed, the annular guide block 702 can follow the displacement of the annular guide rail 14, and the self-locking telescopic rod 4 can be kept in a telescopic state. At this time, the first connecting rod 604 deflects toward the middle and drives the upper movable plate 5 to move upward. When the clamping and fixing is completed, the self-locking telescopic rod 4 can be kept in a locked state. At this time, the welding assembly 7 can follow the clamping assembly 15 to synchronously adjust to the welding position;

[0061] S3: At this time, the welding machine 703 can be turned on and the side of the shell can be welded through the welding head 704, and the motor 3 can be turned on to drive the upper movable plate 5 at the bottom to rotate, and drive the linkage assembly 6 and the welding assembly 7 at the bottom to rotate circumferentially. At this time, the welding assembly 7 can perform circumferential welding on the lamp;

[0062] S4: At the same time, when the active guide ball 705 moves to the top of any fixed guide ball 154, the fixed guide ball 154 is pressurized and drives the longitudinal guide block 152 to move downward. At this time, the limit spring 153 is compressed and drives the clamping block 155 to move downward at the same time. At this time, the clamping at the corresponding position is contacted to avoid welding interference until the welding component 7 is no longer located above the clamping component 15. At this time, the clamping block 155 automatically moves up to continue to complete the clamping of the corresponding point.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

6. A welding method for a welding device for lamp processing according to claim 5, characterized in that: The following steps are involved: S1: When welding the lamp, the lamp can be placed between the four clamping assemblies (15), and the cylinder (11) is turned on to control the cylinder (11) to extend. At this time, the lower movable plate (10) is lowered, and the second connecting rod (123) is pulled to deflect toward the middle. At this time, the multiple locking frames (13) can be pulled relatively close until the multiple clamping assemblies (15) are relatively close to each other, so that the lamp in the middle is clamped and fixed; S2: When the lamp is clamped and fixed, the annular guide block (702) can follow the displacement of the annular guide rail (14), and the self-locking telescopic rod (4) can be kept in a telescopic state. At this time, the first connecting rod (604) is deflected toward the middle and drives the upper movable plate (5) to move upward. When the clamping and fixing is completed, the self-locking telescopic rod (4) can be kept in a locked state, and the welding assembly (7) can follow the clamping assembly (15) to be synchronously adjusted to the welding position; S3: At this time, the welding machine (703) can be turned on and the side of the shell can be welded through the welding head (704), and the motor (3) can be turned on to drive the upper movable plate (5) at the bottom to rotate, and drive the linkage component (6) and the welding component (7) at the bottom to rotate circumferentially. At this time, the welding component (7) can perform circumferential welding on the lamp; S4: At the same time, when the active guide ball (705) moves to the top of any fixed guide ball (154), the fixed guide ball (154) is compressed and drives the longitudinal guide block (152) to move downward. At this time, the limit spring (153) is compressed and drives the clamping block (155) to move downward. At this time, the clamping at the corresponding position is contacted to avoid welding interference until the welding component (7) is no longer located above the clamping component (15). At this time, the clamping block (155) automatically moves up to continue to complete the clamping of the corresponding point.
