[0024] like Figures 1 to 3 As shown, the lead frame material box storage device 100 includes a bracket and a blocking rod 130. The bracket includes a first bracket 111 and a second bracket 112. The first bracket 111 and the second bracket 112 are arranged at intervals, and the first bracket 111 and the second bracket 112 can be arranged close to and far from each other. In the example shown in the figure, the first bracket 111 is fixed, and the second bracket 112 can be arranged close to and far from the first bracket 111. There is a receiving space 101 between the first bracket 111 and the second bracket 112. The receiving space 101 is used to receive the lead frame material box 200 and allow the lead frame material box 200 to move in the receiving space 101. The present invention also includes a guiding device, which guides the second bracket when it moves. The guiding device includes a guide rail 113 and a slider 114. The slider 114 is slidably arranged on the guide rail 113. The second bracket 112 is connected to the slider 114. A locking bolt 115 is arranged on the second bracket 112. By screwing the locking bolt 115 , the locking bolt 115 can be pressed against the guide rail 113 to limit the movement of the second bracket 112 .

[0025] A spacer block 116 is provided between the first bracket 111 and the second bracket 112, and the spacer block 116 is used to fill the gap between the first bracket 111 and the second bracket 112, and support the lead frame magazine 200. A stopper block 117 is also provided in the accommodation space 101. The stopper block 117 is provided in the accommodation space 101 and is located on the moving route of the lead frame magazine 200, and is used to stop the lead frame magazine 200 at a specified position.

[0026] The first bracket 111 and the second bracket 112 are both provided with a cavity (not shown in the figure). The cavity structures on the first bracket 111 and the second bracket 112 are the same and are surrounded by the same structure. Taking the second bracket 112 as an example, the second bracket 112 includes a bottom plate 121 and a box cover 122. The bottom plate 121 and the box cover 122 together surround a cavity. A plurality of pins 123 are provided in the cavity.

[0027] A plurality of baffle rods 130 are arranged in the cavity of the first bracket 111 and the cavity of the second bracket 112, forming two rows of baffle rods 130. Each baffle rod 130 includes a mounting portion 131 and a protrusion 132. The mounting portion 131 and the protrusion 132 are integrally formed. The middle portion of the baffle rod 130 is sleeved on the pin 123 and can rotate around the pin 123. The protrusion 132 protrudes out of the cavity, extends into the accommodating space 101 and is located on the moving route of the lead frame material box 200. A tension spring 140 is arranged in the cavity. One end of the tension spring 140 is connected to the mounting portion 131, and the other end is connected to the first bracket 111. When the lead frame material box 200 enters the accommodating space 101 and moves, it will hit the protrusion 132 of the baffle rod 130. When the protrusion 132 is hit by the lead frame magazine 200, the blocking rod 130 rotates, and the protrusion 132 moves away from the moving path of the lead frame magazine 200, so that the lead frame magazine 200 can continue to move. At this time, the tension spring 140 is stretched to generate elastic force. The lead frame magazine 200 continues to move until it passes over the protrusion 132, and the elastic force of the tension spring 140 resets the blocking rod 130, and the protrusion 132 returns to the moving path of the lead frame magazine 200.

[0028] The lead frame box storage device of the present invention utilizes the accommodation space provided on the bracket to store the empty lead frame boxes after use. The blocking rod can block the lead frame box to prevent the lead frame box from tipping over, especially when the lead frame box with a small depth cannot stand independently, the blocking rod supports the lead frame box to keep it in a stable posture, which is convenient for the next step of taking. An elastic reset device is provided to automatically reset the blocking rod, which is convenient and flexible to use. The second bracket is movably provided, so that the present invention is applicable to lead frame boxes of different widths. A guiding device is provided to keep the second bracket stable when adjusting its position, and it will not tilt during the adjustment process. A locking bolt is provided to keep the second bracket stable and prevent the second bracket from shifting and being unable to be used normally.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention is included in the scope of the claims of the present invention.
