Description

Technical Field

[0001] The utility model relates to the field of lamp production, in particular to an automatic welding machine. Background Art

[0002] The frame of the lamp hanging from the ceiling of the house is a metal frame with adjacent frame edges connected vertically. The frame is made of four L-shaped iron strips (or steel strips) welded end to end. During the production process, the worker aligns the two intersecting L-shaped iron strips vertically with each other, then places the connecting part into the welding rod (welding nozzle) of the spot welding machine for alignment, and then steps on the spot welding machine to perform spot welding, thus welding the two L-shaped iron strips into one. Continuing to weld the adjacent edges, the square frame of the ceiling lamp is obtained. This square frame is then pickled and electrostatically sprayed / painted to obtain a durable ceiling lamp frame. In the process of using L-shaped iron strips to weld into a square frame, it is necessary to manually align the connected L-shaped iron strips vertically with each other and then place them in a spot welding machine for welding. Due to the manual operation of docking and spot welding, there are the following shortcomings: 1. Errors are prone to occur when the two connected L-shaped iron strips are vertically aligned, and the welded square frame will not be vertical, which will make the entire frame easily distorted, affecting production quality; 2. Manual operation of the butt welding nozzle has slow welding efficiency and is prone to waste; 3. During the spot welding process of the butt welding nozzle, the worker's hands are easily overworked, making it difficult to improve production efficiency and failing to achieve good automatic welding. Utility Model Content

[0003] In order to solve the problem that the frame of the ceiling lamp is difficult to be vertically docked and positioned during welding during the manufacturing process, the right angles between the adjacent sides of the frame are not vertical, which causes the entire frame to be distorted, and the manual operation of the butt welding nozzle has a slow welding efficiency and is prone to waste. During the spot welding process of the butt welding nozzle, the worker's hands are easily overworked. The present application provides an automatic welding machine, which is designed with a rotatable vertical frame and a spot welding machine. The spot welding machine can automatically spot weld the L-shaped iron strips in the four corners of the vertical frame. The L-shaped iron strips placed in the vertical frame will be welded into one piece, and the worker can efficiently put the L-shaped iron strips into It is vertically positioned in the positioning groove of the vertical frame, and then the motor automatically controls the rotation of the vertical frame, and the welding position to be welded is rotated to be aligned with the welding nozzle of the spot welding machine. The spot welding machine spot welds the four corners of the vertical frame in turn, and welds the L-shaped iron strips of the vertical frame end to end into a square frame. The square frame is then taken out to complete the welding. It can automatically weld, reducing the trouble of manual operation of the welding nozzle, improving the welding efficiency, and ensuring that the connection angles between adjacent sides are vertical with small errors, and avoiding the angles of the welded square frame being not vertical, thereby causing the entire frame to be distorted and unable to be installed with the lamp body.

[0004] The present invention adopts the following technical scheme: an automatic welding machine, including a base, a motor, a vertical frame, an insert body, and a spot welding machine. The base is provided with a motor and a vertical frame. The rotation of the motor controls the rotation of the vertical frame. The vertical frame is a square frame. Four vertically intersecting positioning grooves of equal length are provided in the vertical sides of the square frame. The intersection angles of the positioning grooves are provided with inserts that are tightly matched with the insert body. The side ends of the L-shaped iron strips can be inserted into the positioning grooves of the vertical frame. When the four L-shaped iron strips are placed in the positioning grooves and intersect vertically, the insert body is located below the vertical intersection of the L-shaped iron strips and intersects with the L-shaped iron strips. The strips are in contact, and the motor controls the vertical frame to rotate the welding position of the four L-shaped iron strips placed in the positioning groove to be aligned with the welding nozzle of the spot welding machine and the middle part of the contact. The welding nozzle of the spot welding machine can automatically move downward to spot weld the L-shaped iron strips of the vertical frame.

It can be welded automatically, reducing the trouble of manual operation of the welding nozzle, improving welding efficiency, and ensuring that the connection angles between adjacent sides are vertical with small errors, thereby avoiding the angles of the welded square frame being non-vertical.

[0006] A base is provided at the lower end of the insert body, and the width of the base is greater than the width of the insert body, thereby increasing the bottom area of ​​the insert body. When the vertical frame rotates to the contact point of the spot welder, the contact point of the spot welder can more easily collide with the base of the insert body for welding.

[0007] The insert body and the base are made of metal copper.

[0008] The upper end of the positioning groove of the vertical frame is provided with a guide opening, which plays a guiding role and increases the opening of the upper end of the positioning groove, making it easier to insert the side end of the L-shaped iron strip into the positioning groove, making it more efficient when placing the L-shaped iron strip.

[0009] The width of the positioning groove of the vertical frame is 0.2MM-0.6MM larger than the width of the L-shaped iron strip, preferably 0.4MM. When the L-shaped iron strip is inserted into the positioning groove, the friction between the L-shaped iron strip and the positioning groove can be reduced, and the L-shaped iron strip can be prevented from loosening in the positioning groove, and the vertical angle of welding can be ensured.

[0010] The vertical sides of the vertical frame are respectively provided with a taking-out port. When the frame is welded, the welded L-shaped iron strip can be taken out by grabbing it with the hand from the taking-out port. The taking-out port is provided to facilitate the placement and removal of the L-shaped iron strip, thereby improving the efficiency of the welding process.

[0011] The vertical frame is made of plastic material, preferably any one of nylon and ABS.

[0012] The spot welding machine and the motor are connected to the circuit module, which controls the spot welding machine and the motor to cooperate with each other, rotates the welding position of the L-shaped iron sheet placed in the positioning groove of the vertical frame to be aligned with the welding nozzle of the spot welding machine, and then controls the welding nozzle of the spot welding machine to move downward, spot welding the four corners of the L-shaped iron sheet in the vertical frame that need to be welded, and welds the L-shaped iron sheet in the vertical frame end to end into a square frame, and then takes out the square frame to complete the welding.

Continuing to weld adjacent sides, the frame of the square ceiling lamp is obtained. In the process of using the L-shaped iron strips 4 to weld the square lamp frame, it is necessary to manually align the welding positions of the two L-shaped iron strips 4 at an intersection and vertically, and then put them into the spot welding machine 1 for welding. Since it is a manual operation, errors are likely to occur when the two L-shaped iron strips 4 are vertically aligned, and the welded square frame is easily distorted. Manually operating the butt welding nozzle 2 has slow welding efficiency and is also prone to produce waste. During the spot welding process of the butt welding nozzle 2, the worker's hands are easily overworked, making it difficult to improve production efficiency and failing to achieve good automatic welding.

[0027] A guide opening 7 is provided at the upper end of the positioning groove 6 of the vertical frame 5. The guide opening 7 plays a guiding role and increases the opening at the upper end of the positioning groove 6, making it easier for the side end of the L-shaped iron strip 4 to be inserted into the positioning groove 6, making it more efficient when placing the L-shaped iron strip 4.

[0028] The width of the positioning groove 6 of the vertical frame 5 is 0.2MM-0.6MM larger than the width of the L-shaped iron strip 4, preferably 0.4MM.
