Description

Technical Field

[0001] The utility model relates to the technical field of lead wire joint processing, in particular to a lead wire joint processing welding device. Background Art

[0002] Lead wires extending outward from the component package. In surface mounted components, it refers to the general term for external leads such as wing-shaped leads, J-shaped leads, and I-shaped leads. The leads need to be welded during the lead processing process. Lead welding is a process that uses metal leads to connect the electrodes on the transistor core with the tube socket lead (i.e., the pin). There are many methods and ways of lead welding, and the most commonly used ones are hot pressing welding, ultrasonic welding, and reverse welding. Lead welding refers to the welding between the coil head and the lead or the welding between the leads. The welding quality has a great impact on the product quality.

[0003] Publication number "CN213105223U" provides a lead connector processing and welding device, including a device body, a welding mechanism is provided at the middle position of the bottom of the fixed plate, the rotating rod top tube sleeve is fixedly connected with a cam, the left end of the driven plate is fixedly connected with a fixed rod, the outer sleeve of the fixed rod is connected with a reset spring, and the bottom of the feed tube is penetrated and evenly distributed with filter holes. In the utility model, the rotating motor drives the rotating rod to rotate, so that the cam rotates, and under the action of the cam, the driven plate drives the fixed rod to move to the left to clamp and weld the connector. After welding is completed, under the action of the reset spring and the cam, the fixed rod moves to the right, and the connector falls into the feed tube. Connectors of different sizes can be clamped and welded, and waste chips such as welding slag can pass through the filter hole and fall into the waste chip box. The finished lead connector slides along the slope into the receiving box, effectively separating the welding slag from the finished connector, which is worthy of vigorous promotion.

[0004] However, the above device still has the following problems during implementation:

[0005] The existing welding devices need to use a cutter to cut off the lead joint during the welding process, and can only weld it after removing the oxide layer and contaminants. Generally, it is cut in advance before processing with the help of scissors, or cut with the cutter provided by the welding machine. The welding machine generally uses a cutter to cut from top to bottom during the cutting process. This cutting method often cannot completely cut off the wire ends wrapped at the lead joint, and the cutting effect is poor, which directly affects the quality of the lead joint after welding.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0027] Embodiment 1:

[0028] A lead joint processing welding device comprises a workbench 1, a welding machine 2 and a welding plate 3, wherein the welding machine 2 is fixedly mounted on the top of the workbench 1, the welding plate 3 is fixedly mounted on the welding end of the welding machine 2, a welding table 4 used in conjunction with the welding plate 3 is fixedly connected to the top of the workbench 1, four legs 5 are fixedly connected to the bottom of the workbench 1, and a cutting mechanism is arranged on the top of the workbench 1 to cut off the lead joint.

[0029] The cutting mechanism includes a hydraulic cylinder 6 fixedly installed on one side of the welding machine 2, the output end of the hydraulic cylinder 6 penetrates to one side of the welding machine 2, and is fixedly connected to a push plate 7, one side of the push plate 7 is fixedly connected to two fixed blocks 8, the top of the fixed block 8 is movably connected to two moving plates 9 through a rotating shaft, one side of the welding table 4 is provided with two blades 10, one side of the blade 10 is fixedly connected to a stabilizing block 11, one end of the moving plate 9 is rotatably connected to the top of the stabilizing block 11 through a rotating shaft, and a wiping mechanism is provided on the top of the workbench 1, which can wipe the waste tin and impurities remaining on the blade 10;

[0030] In this embodiment, by providing a cutting mechanism, when the user needs to weld the lead wire, the user can manually place the lead wire on the welding table 4, and then start the hydraulic cylinder 6 in the cutting mechanism. The movement of the hydraulic cylinder 6 will drive the push plate 7, the fixed block 8 and the movable plate 9 to move, and at the same time squeeze the movable plate 9, so that the movable plate 9 drives the stabilizing block 11 and the blade 10 to move along the trajectory of the electric telescopic rod 19 until the lead wire on the welding table 4 is cut off. The lead wire is cut off on both sides of the cutter at the same time, so that the efficiency is higher and the cutting effect is better, and the phenomenon of residual debris in the lead wire joint due to incomplete cutting during the cutting process, which affects the subsequent welding effect, is effectively avoided;

[0031] The invention solves the problem that the existing welding device needs to use a cutter to cut off the lead joint during the welding process, and can only weld it after removing the oxide layer and contaminants. Generally, it is cut in advance before processing by using scissors, or cut by using the cutter provided by the welding machine 2. In the cutting process, a cutter generally cuts from top to bottom. This cutting method often cannot completely cut off the wire end wrapped at the lead joint, and the cutting effect is poor, which directly affects the quality of the lead after welding.

[0032] Two fixed plates 18 are fixedly connected to the top of the workbench 1, a telescopic rod 19 is fixedly connected to one side of the fixed plate 18, and a telescopic end of the telescopic rod 19 is fixedly connected to one side of the stabilizing block 11;

[0033] By providing the telescopic rod 19 , when the stabilizing block 11 moves, it can move along the trajectory of the telescopic rod 19 , thereby limiting the moving trajectory of the stabilizing block 11 .

[0034] Embodiment 2:

[0035] On the basis of the first embodiment, the cutting mechanism in the first embodiment can play the role of cutting the lead connector, but after cutting, some debris on the lead surface and waste tin splashed on the surface of the soldering station 4 will adhere to the surface of the cutter, and the cutting mechanism does not have the function of wiping them. If they are not cleaned in time, they will accumulate on the surface of the cutter, thereby affecting the subsequent cutting effect. The wiping mechanism in the present application includes a connecting block 12 movably connected to one side of the blade 10, a scraper 13 is fixedly connected to one side of the connecting block 12, a support block 14 is fixedly connected to one side of the blade 10, a spring 15 is fixedly connected to the bottom of the connecting block 12, and one end of the spring 15 away from the connecting block 12 is fixedly connected to the top of the support block 14, and two fixed rods 16 are fixedly connected to the top of the workbench 1, and the top of the fixed rod 16 is fixedly connected to the extrusion plate 17;

[0036] In this embodiment, by providing a wiping mechanism, when the user uses the cutting mechanism, the hydraulic cylinder 6 in the cutting mechanism drives the cutter to move in the opposite direction after cutting the lead wire, and at the same time, the connecting block 12 and the scraper 13 in the wiping mechanism are driven to move. When moving to a certain position, the connecting block 12 is squeezed by the squeezing plate 17. At this time, the spring 15 is in a compressed state. The elastic force generated by the spring 15 drives the connecting block 12, the scraper 13 and the limit block 21 to move along the trajectory of the limit groove 20, so that the impurities on the surface of the blade 10 can be wiped;

[0037] When the connecting block 12 moves to a point where there is no contact with the extrusion plate 17, the spring 15 is no longer restricted, and the elastic force generated by the spring 15 can drive the connecting block 12, the scraper 13 and the limit plate to reset along the track of the limit groove 20;

[0038] The invention solves the problem that after cutting, some debris on the surface of the lead and waste tin splashed on the surface of the cutting table adhere to the surface of the cutter, and the cutting mechanism does not have the function of wiping them. If they are not cleaned in time, they will accumulate on the surface of the cutter, thereby affecting the subsequent cutting effect.

[0039] One side of the extrusion plate 17 is sloped, and the extrusion plate 17 is used in conjunction with the connection block 12;

[0040] By setting one side of the extrusion plate 17 to be sloped, the contact area between the connection block 12 and the extrusion plate 17 can be increased, so that the connection block 12 can better contact with the extrusion plate 17 .

[0041] A limiting groove 20 is provided on one side of the blade 10, and a limiting block 21 used in conjunction with the limiting groove 20 is fixedly connected to one side of the connecting block 12;

[0042] By providing the limiting block 21 and the limiting groove 20 , when the spring 15 is compressed, the connecting block 12 , the scraper 13 and the limiting block 21 can be driven to move along the trajectory of the limiting groove 20 , thereby limiting the moving trajectory of the connecting block 12 .

[0043] One side of the scraper 13 is sloped and fits with one side of the blade 10;

[0044] By setting one side of the scraper 13 to be sloped and in contact with one side of the blade 10, the contact area between the scraper 13 and the blade 10 can be increased, so that the scraper 13 can wipe more cleanly and achieve a better wiping effect when in contact with the blade 10.

[0045] Working principle: When the user needs to weld the lead, the lead is placed on the welding table 4 manually, and then the hydraulic cylinder 6 in the cutting mechanism is started. The movement of the hydraulic cylinder 6 will drive the push plate 7, the fixed block 8 and the movable plate 9 to move, and at the same time squeeze the movable plate 9, so that the movable plate 9 drives the stabilizing block 11 and the blade 10 to move along the track of the electric telescopic rod 19 until the lead on the welding table 4 is cut off. The lead is cut off on both sides of the cutter at the same time, which makes it more efficient and has a better cutting effect, and effectively avoids the phenomenon that the residual debris in the lead joint affects the subsequent welding effect due to incomplete cutting during the cutting process;

[0046] When the user uses the cutting mechanism, the hydraulic cylinder 6 in the cutting mechanism drives the cutter to move in the opposite direction after cutting the lead wire, and at the same time, the connecting block 12 and the scraper 13 in the wiping mechanism are driven to move. When moving to a certain position, the connecting block 12 is squeezed by the squeezing plate 17. At this time, the spring 15 is in a compressed state. The elastic force generated by the spring 15 drives the connecting block 12, the scraper 13 and the limit block 21 to move along the trajectory of the limit groove 20, so that the impurities on the surface of the blade 10 can be wiped off.

[0047] When the connecting block 12 moves to a point where it has no contact with the extrusion plate 17, the spring 15 is no longer restricted. The elastic force generated by the spring 15 can drive the connecting block 12, the scraper 13 and the limit plate to reset along the trajectory of the limit groove 20, thereby avoiding the phenomenon that the scraper 13 will hinder the cutter from continuing to cut after wiping.

[0048] It should be noted that the welding machine 2 and the hydraulic cylinder 6 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. The specific composition and principle of the power supply of the welding machine 2 and the hydraulic cylinder 6 are clear to those skilled in the art, so they will not be described in detail.

[0049] 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.
