Description

Technical Field

[0001] The invention belongs to the technical field of capacitor preparation, and in particular relates to a capacitor core insert welding fixture and a use method thereof. Background Art

[0002] Film capacitors have the advantages of non-polarity, high insulation resistance, excellent frequency characteristics, low loss, good self-healing and open circuit failure, and are widely used in home appliances, new energy and electric vehicles. After the metallized film is wound, heat-set and sprayed with gold, the electrodes need to be led out, usually by welding.

[0003] The 187 plug has the characteristics of good versatility, good conductivity, and low cost, and is widely used in the electronic component industry. When using the 187 plug for lead welding, the plug needs to be welded to the gold-sprayed end face. Since different capacitors have different specifications, that is, different core sizes, the plug requires different exposed heights, and different fixtures need to be designed for each model specification. This results in a large number of fixtures and low efficiency. Therefore, it is necessary to design a welding fixture device that is simple to operate and has good versatility.

[0004] The patent document with announcement number CN209503332U discloses a capacitor plug tooling structure, including an L-shaped base, an adjustable positioning plate, a left plug positioning plate, a right plug positioning plate, and a spring pressure plate. The base is connected to the adjustable positioning plate. The upper part of the adjustable positioning plate is provided with a left plug positioning plate and a right plug positioning plate. The spring pressure plate is respectively arranged on the left plug positioning plate and the right plug positioning plate. The tooling can ensure the positioning accuracy during plug welding, and reduce the operator's pressing action to prevent the plug from loosening during welding, but the structure lacks a structure that helps to record and confirm the position of the plug.

DETAILED DESCRIPTION

[0029] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0030] Example:

[0031] like Figures 1 to 7 As shown, a capacitor core insert welding fixture includes a base 1, an insert positioning slider 2, a positioning baffle 3, a sliding track 6 and an elastic member 7. The base 1 is slidably connected to the insert positioning slider 2 and the positioning baffle 3 respectively, and the sliding track 6 is arranged in the base 1. One end of the elastic member 7 is connected to the sliding track 6, and the other end of the elastic member 7 is connected to the positioning baffle 3.

[0032] A first slide groove 101 is arranged on the top of the base 1 . The first slide groove 101 is rectangular. The positioning baffle 3 is slidably connected to the base 1 through the first slide groove 101 .

[0033] A second slide groove 104 is arranged on the side of the base 1, and third slide grooves 102 are arranged on both sides of the inner wall of the second slide groove 104, and first sliders 201 are arranged on both sides of the insert positioning slider 2. The insert positioning slider 2 is placed in the second slide groove 104. The second slide groove 104 can guide and limit the insert positioning slider 2. The first slider 201 is placed in the third slide groove 102 for sliding connection.

[0034] A scale line 103 is set on one side of the second slide groove 104, a marking line 203 is set on the top of the insert positioning slider 2, a placement groove 204 is set in the insert positioning slider 2, a limiting column 202 is set in the placement groove 204, the insert 4 is set in the placement groove 204, and the limiting column 202 passes through the through hole 401 on the insert 4 to fix it.

[0035] The end of the positioning baffle 3 away from the base 1 is arranged in an arc shape. When the capacitor core 5 is placed in, the arc shape is squeezed, so that the two positioning baffles 3 are forced to move outward. A support column 302 is arranged at the other end of the positioning baffle 3, and a second slider 303 is arranged on the support column 302. The second slider 303 is slidably connected to the sliding track 6.

[0036] First connecting columns 301 are respectively arranged on both sides of the second slider 303, and second connecting columns 601 are respectively arranged on both sides of the sliding track 6. Three sliding tracks 6 are arranged, and a second connecting column 601 is respectively arranged in the middle of both sides of each sliding track 6. Two second sliders 303 are connected on a single track to ensure that the positioning baffle 3 can only move horizontally. A first connecting column 301 is respectively arranged on both sides of each second slider 303. This arrangement enables two elastic members 7 to be respectively arranged on both sides of each sliding track 6, one end of the two elastic members 7 is connected to the same second connecting column 601, and the other ends of the two elastic members 7 are respectively connected to the first connecting columns 301 of the two second sliders 303. This arrangement enables the elastic members 7 to form the same pulling force on the second sliders 303 on both sides, so that the two positioning baffles 3 have a tendency to move toward the middle of the base 1 under the pulling force, so as to facilitate the centering of the capacitor core 5.

[0037] Connecting hooks are respectively arranged at both ends of the elastic member 7. The elastic member 7 can be a spring. The elastic member 7 is connected to the first connecting column 301 and the second connecting column 601 through the connecting hooks. The first connecting column 301 and the second connecting column 601 are both in the shape of a T-shaped cylindrical boss, which is convenient for the elastic member 7 with a hook to hook and prevent it from falling out. The elastic member 7 with the same elastic coefficient is selected. According to Hooke's law, when the elastic member 7 undergoes the same deformation, the tension generated by the elastic member 7 is the same. Therefore, when the capacitor core 5 is inserted between the two positioning baffles 3, the capacitor core 5 will be subjected to the same extrusion force on both sides, and the capacitor core 5 will always be in the middle position of the device, thereby ensuring the stability and consistency of the position of the capacitor core 5 during the welding process.

[0038] The base 1 is made of motherboard or glass fiber board material.

[0039] A method for using a capacitor core insert welding fixture comprises the following steps:

[0040] S1: Place the capacitor core 5 between two positioning baffles 3, and the positioning baffles 3 clamp the capacitor core 5.

[0041] S2: Place the plug 4 into the placement groove 204, then move the plug positioning slider 2 to the position according to the required exposed height of the plug 4, and record the position of the scale line 103 corresponding to the marked line 203, and weld the capacitor core 5 and the plug 4 at this position.

[0042] S3: After one side of the capacitor core 5 is welded, a new insert 4 is installed, the capacitor core 5 is taken out and rotated 180°, the other end of the capacitor core 5 is turned to the side to be welded, and the capacitor core 5 is placed between the two positioning baffles 3 again. After adjusting the position of the scale line 103 corresponding to the marked line 203 to be consistent with step S2, repeat step S2 for welding.
