Description

Technical Field

[0001] The utility model relates to the field of capacitor processing, in particular to a capacitor processing lead welding positioning structure. Background Art

[0002] In the lead welding step of capacitor processing, the lead pins need to be placed on the contacts of the capacitor for spot welding. This step is generally completed by a mechanical positioning and clamping mechanism. However, when the number of leads that need to be welded is large, the mechanical positioning and clamping mechanism needs to be used to sequentially place the lead pins on each contact of the capacitor for lead welding. The work efficiency is low, and the lead pins are prone to warping up and causing cold soldering, which affects the conductive effect of the finished capacitor during use, and ultimately leads to a significant decrease in the use effect of the capacitor. Utility Model Content

[0003] In order to overcome the shortcomings of low efficiency in spot welding of lead pins for multiple contacts of a capacitor and the possibility of lead pins warping and causing cold soldering, the utility model provides a capacitor processing lead welding positioning structure.

[0004] Technical solution: A capacitor processing lead welding positioning structure includes a hollow carrier, a clamping ring, a fixed plate, a lower clamp, an upper clamp, an electrically controlled sliding bracket, a connecting rod, and a fixed frame; the hollow carrier is connected to two left and right clamping rings; the hollow carrier is fixedly connected to a fixed plate; the lower clamp is fixedly connected to the fixed plate; the fixed plate is slidably connected to two electrically controlled sliding brackets; the electrically controlled sliding bracket is connected to a connecting rod; a fixed frame is fixedly connected between the two connecting rod brackets; and the upper clamp is fixedly connected to the fixed frame.

[0005] Furthermore, the clamping rings are slidably connected to the hollow carrier plate; the hollow carrier plate is fixedly connected to two left and right electric push rods; and the telescopic ends of the electric push rods are fixedly connected to the clamping rings.

[0006] Furthermore, the connecting rod is slidably connected to the electrically controlled sliding bracket; two wedge-shaped guide bars are fixedly connected to the hollow carrier plate; and the fixing frame is slidably connected to the wedge-shaped guide bars.

[0007] Furthermore, a compression spring is fixedly connected between the connecting rod and the electrically controlled sliding bracket.

[0008] Furthermore, an oblique pressing block is fixedly connected to the fixing frame, and the oblique pressing block is located at the rear side of the lower clamp.

During the fixed-point welding process, after the manipulator simultaneously places multiple leads between the same number of lower clamps and upper clamps, the electrically controlled sliding bracket synchronously drives all the upper clamps to straighten and flatten the lead pins on each contact of the capacitor, thereby realizing synchronous fixed-point welding of the leads of multiple contacts of the capacitor, improving the efficiency of fixed-point welding of capacitor processing while ensuring the welding effect of the lead pins and contacts. After the fixed-point welding work is completed, the electric push rod controls the clamping ring to loosen the capacitor to complete the welding work, thereby realizing rapid unloading. Through the above processing steps, the technical problems of low efficiency in spot welding of the lead pins of multiple contacts of the capacitor in sequence and the easy existence of lead pin warping leading to cold soldering are solved.

DETAILED DESCRIPTION

[0015] The preferred technical solution of the present utility model is described in detail below with reference to the accompanying drawings.

[0016] Example

[0017] A capacitor processing lead welding positioning structure, such as Figure 1-Figure 3As shown, it includes a hollow carrier 1, a clamping ring 2, a fixing plate 3, a lower clamp 4, an upper clamp 5, an electrically controlled sliding bracket 51, a connecting rod 52, a fixing frame 53, and a spring piece 6; a clamping ring 2 is slidably connected to the left and right sides of the bottom of the hollow carrier 1; an electric push rod 21 is fixedly connected to the left and right sides of the hollow carrier 1; the telescopic ends of the two electric push rods 21 are respectively fixedly connected to a corresponding clamping ring 2; a fixing plate 3 is bolted to the front side of the hollow carrier 1; three lower clamps 4 are bolted to the fixing plate 3; two electrically controlled sliding brackets 51 are slidably connected to the fixing plate 3; two electrically controlled sliding brackets 51 are each connected to a connecting rod 52; a fixing frame 53 is commonly fixedly connected between the two connecting rod 52 brackets; three upper clamps 5 are bolted to the fixing frame 53; and a spring piece 6 is fixedly connected to the left and right sides of the lower clamp 4.

[0018] The two connecting rods 52 are respectively slidably connected to a corresponding electric-controlled sliding bracket 51; two wedge-shaped guide strips 54 are bolted to the hollow carrier 1; the two fixing frames 53 are respectively slidably connected to a corresponding wedge-shaped guide strip 54; a compression spring 55 is commonly fixed between the two connecting rods 52 and a corresponding electric-controlled sliding bracket 51; an inclined pressure block 7 is bolted to the fixing frame 53, and the inclined pressure block 7 is located on the rear side of the lower clamp 4.

[0019] The utility model discloses a capacitor processing lead welding positioning structure. During use, a hollow carrier 1 needs to be externally connected to a welding device. After the operator places the capacitor to be welded between two clamping rings 2 of the hollow carrier 1, a manipulator mounted on the external welding device simultaneously inserts three leads between the corresponding lower clamp 4 and upper clamp 5. The spring sheet 6 can adapt to the lead diameter clamped in the lower clamp 4 to be stretched, and the stretched spring sheet 6 provides a more secure clamping effect on the lead under the reverse elastic force generated by the elastic deformation. At this time, the three lead pins are respectively backward toward the three contacts of the capacitor.

[0020] Afterwards, the electrically controlled sliding bracket 51 drives the connecting rod 52 and the fixing bracket 53 to move backwards, and at the same time, the fixing bracket 53 moves along the wedge-shaped guide strip 54, so that the fixing bracket 53 drives the upper clamp 5 to move backwards along the surface of the lead, so that the lead is straightened by the upper clamp 5 that moves backwards. In this process, the compression spring 55, which is initially in a compressed state, pushes the fixing bracket 53 to move downwards along the wedge-shaped guide strip 54, so that the fixing bracket 53 drives the oblique pressure block 7 to press down the rear end of the lead, forcing the lead pin to be tightly pressed down on the corresponding contact of the capacitor, and then the lead pin and the corresponding contact of the capacitor are firmly welded together by an external welding device, so as to achieve the synchronous completion of the fixed-point welding work of the lead pins and leads of the three contacts of the capacitor, while improving the fixed-point welding work efficiency of the capacitor processing, and ensuring the welding effect of the lead pins and contacts.

[0021] Finally, the two electric push rods 21 drive the two clamping rings 2 to move away from each other, so that the capacitor that has completed the welding work is loosened by the two clamping rings 2 and falls downward by itself, thereby completing the rapid unloading work.

[0022] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
