[0028] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below with reference to specific drawings.

[0029] See Figure 1 , what is shown in the figure is a lamp pin bending device for a halogen lamp, including: a workstation turntable 11, which is used to drive a number of processing workstations to perform uniform circular motion in a horizontal plane; a number of lamp holder positioning mechanisms 12, which are used to clamp and position the glass shell and the base of the lamp body, and a number of lamp holder positioning mechanisms 12 are respectively arranged equidistantly on the workstation turntable 11; a lamp pin straightening mechanism 30, which is used to straighten the lamp pins at the bottom of the lamp holder and make the lamp pins vertically downward; a lamp pin bending mechanism 40, which is used to bend the lower part of the lamp pins at the bottom of the lamp holder, and a foot receiving space for providing a short lamp pin is formed on both sides of the bottom of the lamp pin.

[0030] Specifically, the lamp holder positioning mechanism 12 includes a bottom plate 13 and a positioning plate 14. One end of the bottom plate 13 is fixedly arranged on the working station turntable 11; an installation groove is arranged at the top of the other end of the bottom plate 13, and the positioning plate 14 is installed in the installation groove of the bottom plate 13; a plurality of clamping grooves are formed at the bottom of the positioning plate 14, and the bumps around the lamp cap of the halogen lamp are clamped in the clamping grooves of the positioning plate 14.

[0031] The working station turntable 11 of the utility model realizes the circulating processing action of the assembly line, and each lamp holder positioning mechanism 12 forms a processing station respectively; the lamp pin straightening mechanism 30 ensures the perpendicularity between the top end of the lamp pin and the molybdenum sheet, ensuring good contact at the butt joint all the time. The lamp pin bending mechanism 40 can not only ensure the perpendicularity between the upper part of the lamp pin and the molybdenum sheet, but also bend the lower part of the lamp pin, facilitating the subsequent welding of the short lamp pin; after the bottom parts of a pair of lamp pins are bent, the welding area will be wider; it makes up for the phenomenon of gaps in the vertical surface welding. Welding is carried out at an inclined angle at the bending part, and the welding parts are located in different planes, and the welding effect is more stable.

[0032] Further, in combination with Figure 2 , the lamp pin straightening mechanism 30 includes a straightening seat 31, a width fixing component 33, and a clamping component 32. The clamping component 32 includes a slide rail seat 321, a pair of clamping sliders 322, and a pair of clamping blocks 323. One side of the slide rail seat 321 is fixed on the straightening seat 31, and a pair of clamping sliders 322 slide relatively in the slide rails at the top of the slide rail seat 321; the lower parts of a pair of clamping blocks 323 are symmetrically arranged on the outer sides of a pair of clamping sliders 322, and the inner sides of the upper parts of a pair of clamping blocks 323 clamp a pair of lamp pins of the lamp holder simultaneously.

[0033] The width fixing component 33 includes a width fixing seat 331 and a width fixing plate 332. The bottom of the width fixing seat 331 is fixedly arranged on the top of the straightening seat 31, one end of the width fixing plate 332 is fixedly arranged on the top of the width fixing seat 331, and the width fixing plate 332 is horizontally inserted into the inner sides of a pair of slide rail seats.

[0034] The above-mentioned pair of clamping sliders 322 of the clamping component 32 slide relatively on the top of the slide rail seat 321, and the width fixing plate 332 of the width fixing component is used for lateral width limiting between a pair of clamping sliders 322, preventing the pair of clamping blocks 323 from clamping the lamp pins of the lamp holder too loosely to be straightened or too tightly to be damaged.

[0035] The lamp pin clamping and straightening mechanism 30 further includes a height fixing component 34. The height fixing component 34 includes a first height fixing cylinder 341 of the clamping and straightening seat 31 and a second height fixing cylinder 342 of the slide rail seat 321. The first height fixing cylinder 341 is used to support the lamp pin clamping and straightening mechanism 30 to be flush with the station turntable 11, and the second height fixing cylinder 342 is used to adjust the clamping blocks 323 to be located on both sides of the lamp pins. Specifically, the first height fixing cylinder 341 and the second height fixing cylinder 342 are respectively arranged longitudinally; the first height fixing cylinder 341 of the above height fixing component 34 roughly adjusts the height, and the second height fixing cylinder 342 finely adjusts the height, so that the clamping position can be positioned more accurately.

[0036] Further, in combination with Figure 3 and Figure 4 , the lamp pin bending mechanism 40 includes a bending seat 41, an inner clamping component 42, and an outer clamping component 43. The inner clamping component 42 includes an inner clamping seat 421, inner clamping sliders 422, and inner clamping blocks 423. One side of the inner clamping seat 421 is fixed on the bending seat 41, and a pair of inner clamping sliders 422 slide relative to each other in the slide rails on the top of the inner clamping seat 421; the lower parts of a pair of inner clamping blocks 423 are symmetrically arranged on the outer sides of a pair of inner clamping sliders 422, and the upper outer sides of a pair of inner clamping blocks 423 are simultaneously in close contact with the inner sides of a pair of lamp pins of the lamp base. The inner clamping blocks 423 of a pair of inner clamping components 42 are integrally in an eight - character shape 424.

[0037] The outer clamping component 43 includes an outer clamping seat 431, outer clamping sliders 432, and outer clamping blocks 433. One side of the outer clamping seat 431 is fixed on the bending seat 41, and a pair of outer clamping sliders 432 slide relative to each other in the slide rails on the top of the outer clamping seat 431; the lower parts of a pair of outer clamping blocks 433 are symmetrically arranged on the outer sides of a pair of outer clamping sliders 432, and the upper inner sides of a pair of outer clamping blocks 433 simultaneously press the outer sides of a pair of lamp pins of the lamp base. The cross - section of the whole upper part of the outer clamping component 43 is in a π - shape, and the whole side of the outer clamping component 43 is in an L - shape.

[0038] Specifically, triangular grooves are respectively vertically arranged on the left and right side surfaces of the slide rails of the inner clamping seat 421 and the outer clamping seat 431, and triangular protrusions are respectively vertically arranged on the left and right side surfaces of the inner clamping sliders 422 and the outer clamping sliders 432; the sliding effect is better. The cross - sections of a pair of inner clamping sliders 422 and outer clamping sliders 432 are in an inverted T - shape.

[0039] The working principle of the above lamp pin bending mechanism 40 is as follows: First, the piston rod of the inner clamping cylinder of the inner clamping seat 421 extends vertically upward, driving the tops of a pair of adjacent inner clamping blocks 423 to be inserted between the inner sides of a pair of lamp pins of the lamp socket; at the same time, the piston rod of the outer clamping cylinder of the outer clamping seat 431 extends vertically upward, driving the tops of a pair of outer clamping blocks 433 to face one end of the inner clamping block 423 and be located outside a pair of lamp pins of the lamp socket; finally, pneumatically drive a pair of inner clamping sliders 422 to slide outward finely, pneumatically drive a pair of outer clamping sliders 432 to slide inward finely, and the eight-shaped 424 of a pair of inner clamping blocks 423 cooperates with the square surfaces of the outer clamping blocks 433, thereby bending a pair of lamp pins of the lamp socket.

[0040] The inner clamping assembly 42 and the outer clamping assembly 43 of the above lamp pin bending mechanism 40 first perform rough positioning, and then finely slide and clamp a pair of lamp pins through the inner clamping sliders 422 and the outer clamping sliders 432, without damaging or bruising the lamp pins, and the fine positioning does not affect the verticality of the upper part of the lamp pins.

[0041] The above has shown and described the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
