DETAILED DESCRIPTION

[0020] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0021] Referring to Figs. 1 to 4 A lead frame clamp comprises a support frame 100, the support frame 100 comprises a first frame 110, a second frame 120, a third frame 130 and a fourth frame 140 connected head to tail, wherein the first frame 110 is opposite to the third frame 130, and the second frame 120 is opposite to the fourth frame 140. The second frame 120 is connected with a plurality of first support rods 150 extending towards the fourth frame 140, the fourth frame 140 is provided with a plurality of second support rods 160 extending towards the second frame 120, and the first support rods 150 and the second support rods 160 are corresponded one to one in position and leave spaces between them, and the first support rods 150, the second support rods 160, the first frame 110 and the second frame 120 are parallel to each other. The first support rods 150 and the second support rods 160 are both installed with support pieces 200 on both sides, and the inner side of the first frame 110 and the inner layer of the third frame 130 are also installed with support pieces 200, the lead frame is placed on the support pieces 200 between the adjacent first frame 110 or the second frame 120, and the support pieces 200 on the first frame 110 and the third frame 130 also support the lead frame.

[0022] The support 200 comprises a first support plate 210, and the first support plate 210 is connected with a second support plate 220 which is perpendicular to the first support plate, so that the first support plate 210 and the second support plate 220 form an inverted T-shaped structure, and two adjacent support 200 commonly fix a group of lead frames. The first support rod 150 and the second support rod 160 are provided with a moving groove 300 extending in the length direction. The center of the moving groove 300 is provided with a guide 320 extending in the length direction of the moving groove 300, and the length direction of the guide 320 is provided with a first guide surface 321 and a second guide surface 322, respectively. The first guide surface 321 and the second guide surface 322 are both inclined in the length direction and the inclined directions are opposite, so that the guide 320 forms a trapezoidal structure. The bottom surface of the moving groove 300 on the side of the first guide surface 321 and the bottom surface of the moving groove 300 on the side of the second guide surface 322 are both provided with a guide groove 310, and the guide groove 310 is parallel to the corresponding first guide surface 321 or second guide surface 322. The first support plate 210 partially extends into the moving groove 300, and the part extending into the moving groove 300 is provided with a guide block 211, and the guide block 211 is embedded in the guide groove 310, so that the first support plate 210 can move along the first guide surface 321 or the second guide surface 322. The guide 320 is provided with a support 200 on both sides, and the part of the first support plate 210 extending into the moving groove 300 is provided with a fixed plate 230, and the fixed plate 230 is higher than the guide 320. The upper part of the fixed plate 230 is provided with a fixed ring 240, and the position of the fixed ring 240 is also higher than the guide 320.
