Description

Technical Field

[0001] The invention relates to the technical field of lead welding, in particular to an automatic welding tool for leads. Background Art

[0002] Lead welding mainly uses metal tin to weld one end of the lead to the product. Tin soldering is a welding method that uses low-melting-point metal solder to melt and then penetrate and fill the gap between metal parts. Because the solder is often a tin-based alloy, it is named so. A soldering iron is often used as a heating tool. It is widely used in the electronics industry.

[0003] The traditional lead welding process requires the operator to hold the lead and place the product in the welding position. It is necessary to ensure that the end of the lead to be welded is placed at the soldering point of the product, where a tin bar is set above the product. Then the welding head is operated to press one end of the tin bar onto the lead and the product, and the tin bar is melted by the high-temperature welding head so that the molten tin material connects the lead and the product. After the tinned material cools down, a stable connection is ensured between the lead and the product. This welding method requires manual stabilization of the lead and product structure. When stabilizing the structure to be welded, the high-temperature welding gun will move toward the welding point. This welding method has safety hazards and requires the operator to concentrate at all times. The welding process must be carried out strictly according to the process. When the operator is fatigued due to repetitive work, welding failures and injuries from the high-temperature welding head are very likely to occur.

[0004] Based on this, an automated welding tool for leads is proposed. Summary of the invention

[0030] Specifically, Figure 1 As shown, a rotating motor 3 is fixedly connected to the fixed plate 1, and the cam 4 and the half gear plate 5 are fixedly connected to the output end of the rotating motor 3. The rotating motor 3 is a fixed structure, and the output shaft of the rotating motor 3 and the fixed plate 1 are perpendicular to each other.

[0031] Specifically, Figure 2 and Figure 3As shown, the fixed column 20 is connected to the limit clamp 18, the limit frame 6 is slidably connected to the limit clamp 18, the fixed column 20 is connected through the limit clamp 18, the fixed column 20 and the limit clamp 18 are perpendicular to each other, a slide groove 19 is provided on the limit frame 6, the fixed column 20 is slidably connected to the slide groove 19, the lower end of the limit clamp 18 is connected to the spring block 13, and the limit clamp 18 is connected to the push spring 14 through the spring block 13.

[0032] Specifically, Figure 2 and Figure 3 As shown, one end of the limit frame 6 is rotatably connected to a roller 36, and the roller 36 abuts against the outer side of the cam 4. By setting the roller 36 structure, the transmission wear between the cam 4 and the limit frame 6 is reduced, and the transmission stability and equipment durability are improved.

[0033] Specifically, Figure 5 As shown, the limit member includes an abutment block 32, which is slidably connected to the load-bearing gear 8, and a slide bar 33 is connected to the abutment block 32, and the slide bar 33 is vertically fixedly connected to the abutment block 32, and the upper end of the slide bar 33 is slidably connected between the guide ring 22 and the fixed plate 12, and a surround block 31 is connected to the load-bearing gear 8, and an abutment spring 34 is connected between the surround block 31 and the abutment block 32, and the fixed plate 12 is connected to the guide ring 22 through the connecting block 21, and the connecting block 21 is used to stabilize the connection state between the fixed plate 12 and the guide ring 22, and a notch 23 is provided on the fixed plate 12, and the notch 23 is the area where the product is initially placed, and a protrusion 24 is connected to the guide ring 22, and the protrusion 24 is the area where the product is removed from the load-bearing gear 8 after welding, and a groove corresponding to the protrusion 24 is provided on the fixed plate 12.

[0034] Specifically, Figure 5 As shown, a limiting block 30 is connected to the load-bearing gear 8, and an abutment block 32 is slidably connected between the limiting blocks 30. The limiting block 30 is fixedly connected to the upper surface of the load-bearing gear 8. The limiting block 30 is arranged on the outside of the abutment block 32 to ensure the stability of the abutment block 32 sliding on the load-bearing gear 8.

[0035] Specifically, Figure 3 , Figure 4 and Figure 5As shown, the transmission mechanism includes a lead gear 11, one end of the fixed frame 9 is connected to a support seat 15, the support seat 15 is fixedly connected to the limit clamp 18, the lead gear 11 is rotatably connected to the support seat 15 through a rotating shaft 16, and the lead gear 11 has two static states, one of which is a state in which the lead tube 29 rotates to be located above the load-bearing gear 8, and the other is a state in which the lead tube 29 is away from the load-bearing gear 8. In the former, the pressing block 27 can press the button 25, and in the latter, the pressing block 27 and the button 25 are separated from each other. A rotating block 28 is connected to the upper end of the rotating shaft 16, and a lead tube 29 is connected to one side of the rotating block 28. When the lead is placed in the lead tube 29, the lead tube 29 is away from the load-bearing gear 8, and one end of the lead with the tin bar is exposed at one end of the lead tube 29. The remaining structure of the lead is inserted into the lead tube 29. Before placing the lead, it is necessary to cut a certain length of the tin bar and wrap it around one end of the exposed metal wire of the lead. In order to improve the connection stability between the tin bar and one end of the lead, the tin bar can be pinched into a flat shape and clamped at one end of the lead.

[0036] Specifically, Figure 3 and Figure 4 As shown, a controller 17 is connected to one side of the support base 15, a button 25 is connected to the controller 17, a pressing block 27 is connected to the lower end of the lead gear 11, the lead gear 11 and the lower gear 26 are meshed with each other, and by setting the controller 17 and the button 25 structure, when the lead tube 29 rotates to the welding position, the button 25 structure must be pressed, and the welding operation starts at this time, and there is no need for the operator to manually control the welder 10, thereby improving the degree of automation of the equipment. The button 25 structure is electrically connected to the controller 17, and the controller 17 is electrically connected to the welder 10, and the transmission delay of the welding signal between the structures is low.

[0037] In summary, the automated welding tooling for leads provided in the present embodiment needs to place the product in the placement slot 35 on the load-bearing gear 8 when it is necessary to perform lead welding on the product, wherein the placement direction of the product needs to be strictly in accordance with the regulations, that is, a slot structure is provided on the product, and the slot can be docked with the abutment block 32, thereby limiting the rotation of the product and avoiding the problem that one end of the lead cannot be welded to the corresponding welding point of the product when the product is placed at an incorrect angle. When placing the product, it is necessary to push the slide bar 33 structure and push the slide bar 33 into the notch 23. At this time, the abutment block 32 slides between the limit blocks 30 and moves in the direction away from the placement slot 35. At this time, the operator can place the product to be welded in the placement slot 35, and at this time release the slide bar 33, and the abutment spring 34 pushes the abutment block 32 to move, so that one end of the abutment block 32 abuts against the slot on the outside of the product, thereby completing the positioning of the product structure and angle.

[0038] After the product is placed and fixed, the operator starts the rotating motor 3. The rotating motor 3 is a reduction motor, so that the output end of the rotating motor 3 is in a low-speed rotation state, which can drive the cam 4 and the half-toothed disc 5 connected to its output end to rotate in a low-speed state. The outer side of the half-toothed disc 5 is connected to an arc-shaped rack structure with a certain angle range, so that when the half-toothed disc 5 rotates, it can intermittently drive the load-bearing gear 8 to rotate. When the tooth structure on the outer side of the half-toothed disc 5 is engaged with the load-bearing gear 8, when the half-toothed disc 5 rotates, the load-bearing gear 8 will rotate, and when the tooth structure on the outer side of the half-toothed disc 5 is separated from the load-bearing gear 8, the half-toothed disc 5 rotates, and the load-bearing gear 8 will not rotate;

[0039] A cam 4 structure is provided below the half toothed disc 5. When the outer tooth structure of the half toothed disc 5 is to be meshed with the load-bearing gear 8, the cam 4 structure will push the limit frame 6 to slide in advance, so that the limit tooth 7 at one end of the limit frame 6 is separated from the load-bearing gear 8, ensuring that the half toothed disc 5 can drive the load-bearing gear 8 to rotate. When the teeth on the outer side of the half toothed disc 5 are separated from the load-bearing gear 8, the minimum radius portion on the cam 4 will abut against the roller 36. At this time, the limit frame 6 will, under the action of the push spring 14, pull the limit tooth 7 structure to re-engage the load-bearing gear 8, avoiding the load-bearing gear 8 from continuing to rotate due to inertia, thereby stabilizing the structure of the load-bearing gear 8, ensuring that the product can stably rotate to the bottom of the welder 10, avoiding the structural deviation between the welder 10 and the product, and improving the welding accuracy.

[0040] One end of the limit frame 6 is rotatably connected to a roller 36 structure, and the outer side of the roller 36 abuts against the cam 4 structure, and the two structures are in rolling contact with each other. By setting the roller 36 structure, the friction between the structures is reduced, the structural wear is reduced, and the durability of the equipment is improved. The two ends of the push spring 14 are respectively fixedly connected to the spring block 13 connected to the lower end of the limit frame 6 and the spring block 13 connected to the lower end of the limit clip 18, and the push spring 14 can push the roller 36 connected to one end of the limit frame 6 to abut against the cam 4 structure;

[0041] Since the load-bearing gear 8 is fixedly connected to the lower gear 26, when the load-bearing gear 8 rotates intermittently, the lower gear 26 rotates synchronously and intermittently, and the lower gear 26 and the lead gear 11 are meshed with each other. The rotation of the lead gear 11 can drive the rotating block 28 and the lead tube 29 fixedly connected thereto to rotate. After the half-toothed disc 5 rotates one circle, it can drive the load-bearing gear 8 and the lower gear 26 to rotate one-eighth of a circle, and can drive the lead gear 11 to rotate half a circle. Therefore, after the half-toothed disc 5 rotates two circles, the load-bearing gear 8 can rotate a quarter of a circle. At this time, the placed product can be rotated to the bottom of the welder 10, and one end of the lead tube 29 with the lead to be welded is placed toward the product, the lead tube 29 is located above the product, and one end of the lead is located in the area to be welded of the product In order to solder the lead wire to the product through the tin bar, one end of the lead wire needs to be pre-processed, that is, a certain length of tin bar is wound around one end of the lead wire. In order to improve the welding accuracy, the length of the tin bar needs to be controlled to avoid the tin bar being too long, so that the molten tin material flows to the rest of the product during welding, or the tin bar is too short to stably connect one end of the lead wire to the area to be welded of the product. The operator only needs to insert the corresponding lead wire into the lead tube 29. At this time, the timing of inserting the lead wire is when one end of the lead tube 29 is away from the load-bearing gear 8, and the timing of welding is when the lead tube 29 is facing the load-bearing gear 8. There is a certain interval time for switching between the two structural states, which allows the operator to place the lead wire. The time is related to the speed of the rotating motor 3;

[0042] When the lead gear 11 rotates until the pressing block 27 connected to the lower end contacts the button 25, since the two sides of the pressing block 27 are inclined structures, that is, the pressing block 27 can easily press the button 25 by rotating. When the button 25 is pressed, the button 25 transmits the pressing signal to the controller 17, and the controller 17 transmits the signal to the welder 10 through the cable. At this time, the lower end of the welder 10 extends to drive the high-temperature welding head to drop in height, that is, when the button 25 structure is pressed, the welder 10 is controlled by the controller 17 to operate to achieve welding of the product. At this time, one end of the welder 10 shrinks, but the button 25 structure is still pressed. Therefore, when the button 25 structure is pressed, the welder 10 can control the welding head to expand and contract back and forth. At this time, the tin strip wrapped around the lead is melted and welded to the product. When the half-toothed disc 5 is idling without driving the bearing gear 8 to rotate, the tin material connecting the lead and the product begins to cool and solidify. Then, when the bearing gear 8 rotates, the lead can be pulled out of the lead tube 29.

[0043] When the welded product moves to the position below the protrusion 24, the slide bar 33 extends along the guide ring 22 and the protrusion 24 on the fixed plate 12, and the abutment block 32 starts to slide away from the placement groove 35. The operator can easily remove the welded product from the placement groove 35 to complete the welding operation of a single product and the lead wire.

[0044] The welding tool can simplify the welding operation of the operator. The operator only needs to place the lead and the product, and the product can be automatically welded to the lead. The product can be removed after the welding is completed. The use of the welding tool can improve the welding efficiency and ensure the accuracy of the product's welding position.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
