DETAILED DESCRIPTION

[0035] In order to make the skilled in the art more clear and clear the technical scheme of the present application, the technical scheme of the present application will be described in detail below in conjunction with the drawings, but the embodiments of the present application are not limited thereto.

[0036] As Figures 1 to 8 shown, an axial component forming and foot cutting device, comprising positioning mechanism 1, spacing adjustment mechanism 2, support mechanism 3, forming mechanism 4 and foot cutting mechanism 5;

[0037] The left and right two positioning mechanisms 1 are fixedly arranged at the upper end of the spacing adjustment mechanism 2, and are used for positioning the axial component 6;

[0038] The spacing adjustment mechanism 2 is arranged on both sides of the base, and is used for adjusting the spacing between the two positioning adjustment mechanisms;

[0039] The support mechanism 3 is arranged between the spacing adjustment mechanism 2, and is used for supporting the axial component 6;

[0040] The forming mechanism 4 is used for bending and forming the pin of the axial component 6;

[0041] The foot cutting mechanism 5 is used for cutting the formed pin.

[0042] The positioning mechanism 1 comprises pneumatic hand claw 11 and positioning plate 12, and the positioning plate 12 comprises upper positioning plate 121 and lower positioning plate 122, the upper positioning plate 121 is fixed on the upper pneumatic hand claw, and the lower positioning plate 122 is fixed on the lower pneumatic hand claw.

[0043] The lower edge of the upper positioning plate 121 is provided with a protrusion, and the upper edge of the lower positioning plate 122 is provided with a groove, the protrusion and the groove correspond, and are used for positioning the pin.

[0044] The distance adjusting mechanism 2 comprises a gas claw support 21, a screw nut 22, a sliding block 23, a guide rail 24, a screw 25 and a motor 26, the guide rail 24 is fixed on the base, the sliding block 23 is slidably connected with the guide rail 24, the screw nut 22 is fixedly connected with the sliding block 23 through a connecting piece 27, the gas claw support 21 is fixedly connected with the screw nut 22 through a connecting block 28, the screw 25 is connected with the two screw nuts 22, the screw 25 is connected with the motor 26 through a coupling, and the gas claw 11 is fixed on the gas claw support 21.

[0045] The supporting mechanism 3 comprises a supporting block 31 and a stand 32, the supporting block 31 is fixed on the top end of the stand 32, and the stand 32 is fixed on the base plate. The upper surface of the supporting block 31 is provided with a stepped surface, so as to support axial components 6 of different sizes.

[0046] The supporting block 31 is slightly higher than the position of the component body when the claw is opened, so that the component is tangent to the supporting block 31 and is supported to a certain height, and the supporting block 31 has three functions: 1. As a reference, the supporting block 31 is equivalent to a welded PCB, so that the body of each different axial component 6 can guarantee the same pin size when the cutter 51 shears the pin along the lower edge of the lower positioning plate 122; 2. The length of the axial component 6 pin is guaranteed through the relationship among the supporting plate, the lower edge of the lower positioning plate 122 and the groove; in order to guarantee different pin lengths, the supporting plate is provided with a stepped surface, so that multiple pin lengths can be sheared without replacing the positioning plate 12 and the supporting plate; 3. After the axial component 6 is formed, the supporting plate is slightly higher than the position of the axial component 6 when the positioning plate 12 is loosened, so that an upward thrust is provided for the axial component 6, so that the axial component 6 can be separated from the positioning plate 12, thereby facilitating the taking or sucking of the axial component 6 by the robot suction claw.

[0047] The forming mechanism 4 comprises a forming roller 41, a reciprocating air cylinder 42 and a guide rail 43, the forming roller 41 is arranged on a roller support 44 through a shaft, the roller support 44 is arranged on the reciprocating air cylinder 42 through a roller connecting piece 45 and a floating head 46, the rear side of the roller connecting piece 45 is provided with a sliding block 47, and the sliding block 47 is slidably connected with the guide rail 43.

[0048] The forming roller 41 is provided with a circular groove, so that the pins of the axial component 6 are not uneven during the forming process.

[0049] The lead-cutting mechanism includes a cutter 51, a lead-pressing rod 52, a lead-cutting cylinder 53, a slider 54, and a guide rail 55. The cutter 51 and the lead-pressing rod 52 are fixedly mounted on one end of the L-shaped connector 56. The lead-cutting cylinder 53 is fixedly connected to the other end of the L-shaped connector 56 via a floating head 46. The slider 54 is located at the bottom of the L-shaped connector 56, and the guide rail is fixed to the bracket. The slider 54 and the guide rail 55 cooperate with each other. A spring is provided on the lead-pressing rod 52, which includes a spring-loaded rod and a fixed rod. The spring is located between the spring-loaded rod and the fixed rod. During lead cutting, the lead is first pressed down by the spring-loaded rod to avoid damage to the lead due to hard contact.

[0050] The steps include:

[0051] The first step is to adjust the molding spacing.

[0052] First, based on the forming spacing of the axial component 6, the motor 26 drives the lead screw 25 to rotate, thereby adjusting the spacing between the left and right positioning mechanisms 1, and thus adjusting the spacing between the left and right positioning plates 12. The rotation of the motor 26 adjusts the spacing between the left and right positioning plates 12, which corresponds to the hole spacing on the PCB board where the axial component 6 is located.

[0053] After the spacing adjustment is completed, place the axial component 6 in the corresponding groove below the positioning plate 12. The positioning plate 12 has corresponding groove sizes and corresponding chamfer radius for different pin sizes of the axial component 6, so that axial components 6 with different pin sizes can be positioned.

[0054] The axial component 6 is positioned by pressing the pins at both ends of the axial component 6 body with the positioning plate 12. Pressing the pins at both ends of the body can prevent damage to the axial component 6 body during the forming process.

[0055] The second step involves molding by molding mechanism 4.

[0056] After the first step, the axial component 6 is clamped at the positioning plate 12. At this time, the forming mechanism 4 provides power through the reciprocating cylinder 42, and the forming roller 41 moves downward. The surface of the forming roller 41 has a circular groove, the position of which corresponds to the position of the positioning groove of the axial component 6 on the positioning plate 12.

[0057] When the forming roller 41 moves downward and contacts the pin of the axial component 6, the pin is positioned in the circular groove of the forming roller 41 and is bent downward as the forming roller 41 forms the pin. The circular groove on the surface of the forming roller 41 positions the pin of the axial component 6 well, ensuring that the pins on both sides are not parallel during the forming process, thus ensuring the forming quality.

[0058] The third step is for the cutting mechanism 5 to cut the feet.

[0059] After the forming process of the axial component 6 is completed, the pneumatic hand claw 11 is loosened, and the axial component 6 is lowered in the positioning groove of the positioning plate 12 along with the loosening of the pneumatic hand claw 11. In order to meet the different welding pin lengths of the axial component 6, a support block 31 of the axial component 6 is placed below the positioning plate 12, the support block 31 is tangent to the axial component 6 being processed, and the axial component 6 is slightly higher than the position of the groove of the lower positioning plate 122 during forming. In this way, the axial component 6 is guaranteed not to be tightly attached to the positioning plate 12, and the axial component 6 can be based on the support block 31. The distance from a certain stepped surface of the support block 31 to the lower edge of the lower positioning plate 122 is the welding length of the pin of the axial component 6.

[0060] The upper surface of the support block 31 is processed into a stepped surface, and the different stepped surfaces of the support block 31 to the lower edge of the lower positioning plate 122 have different heights, so that different pin sizes of the axial component 6 can be processed. Figure 5 As shown in the figure, the support block 31 has two stepped surfaces with different heights, which can meet the requirements of two pin sizes. After the support block 31 supports the axial component 6, the pin cutting cylinder 53 of the pin cutting mechanism 5 extends, and the pin is first pressed by the pin pressing rod 52 with a spring to ensure the stability of the pin during the pin cutting process. Then, the cutter 51 cuts off the excess pin under the thrust of the pin cutting cylinder 53 (forming a scissors-like structure) to obtain the required size.

[0061] After the same type of axial component 6 is completed, the above three steps can be operated when processing other types of axial components 6. The same component no longer needs to be adjusted in distance, and a plurality of axial components 6 can be met by adjusting the distance. In this embodiment, the distance from the lower edge of the positioning plate 12 to the stepped surface of the support block 31 has two kinds, which can meet the requirements of two types of pin sizes, two types of component forming radii, and a plurality of forming distance processing requirements.

[0062] The present application can meet the forming and pin cutting requirements of any axial component 6. The left and right distance of the positioning plate 12 can be changed by the motor 26 driving the lead screw 25 to meet the different forming distances of the axial component 6. According to the packaging requirements, the corresponding positioning plate 12 and support block 31 are designed to meet the requirements of the axial component 6 forming and pin cutting, and can be used with the upper computer. Common parameters of the axial component 6 are established, and the upper computer sends instructions to automatically adjust the forming and pin cutting device to meet the pre-welding processing requirements. Combined with the three-axis robot, the loading and unloading operations can be realized, the automation of the axial component 6 forming, pin cutting and pre-welding processing operations can be realized, and the production efficiency can be greatly improved.

[0063] The above merely describes the best mode of the present application, and is not intended to limit the present application in any form. Any person skilled in the art can make many possible changes and modifications to the present application without departing from the scope of the present application, and such changes and modifications shall all fall within the protection scope of the present application.
