[0002] In the preparation of semiconductor packaging devices, in order to package the chip on the lead frame as a carrier, the lead frame array is generally placed in a magazine, and then the magazine is placed in the loading mechanism of the packaging equipment. Then, the lead frames are sequentially sent out from the magazine through the pulling or pushing mechanism of the packaging equipment for core bonding packaging. At present, when switching between loading a magazine loaded with lead frames and unloading an empty magazine, an operator takes a single magazine. Some equipment is also equipped with two rotation positions to improve efficiency, which can load two magazines at a time, but the upper and lower taking of the magazines still needs to be manually operated at the rotation position. However, because the actual operating space of the magazine placement position or rotation position of the packaging equipment is limited, it is not very convenient to operate, and the operation cannot be released, otherwise it may cause bumps and damage to the magazine or equipment.

[0015] Figure 2 It is a schematic diagram of the local structure of an embodiment of the present application. DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] The embodiment of the present application provides a transfer mechanism for packaging and loading materials, such as Figure 1 and Figure 2 As shown, it is used to transport the material box 2 and load the material box 2 onto the material box placement position of the packaging equipment. The transfer mechanism includes an endless conveyor belt, a lifting bar 41, etc.

[0018] Specifically, a plurality of pairs of telescopic rods 1 are arrayed on the outer surface of the belt body of the endless conveyor belt, and a top plate 11 is provided on the top of each pair of telescopic rods 1. The top plate 11 is used to carry the material box 2 and engages with the groove at the bottom of the material box 2 when carrying.

[0019] There is a pair of spaced-apart lifting bars 41, which are arranged horizontally and are located on both sides above the horizontal section of the endless conveyor belt, and are movable in a vertical direction perpendicular to the horizontal section of the belt; specifically, the lifting bars 41 are connected to the movable end of the vertical cylinder 4 to realize its lifting and lowering movement in the vertical direction.

[0020] The material box is placed above the horizontal section belt body, which includes a pair of concave plates 3 spaced apart on both sides of the horizontal section belt body and a pair of symmetrically arranged L-shaped clamps 31 that fit in the concave plates 3. The horizontal section of the L-shaped clamp 31 slides in the slide groove of the horizontal section of the concave plate 3, and the vertical section of the L-shaped clamp 31 is connected to the vertical section of the concave plate 3 through a spring; here, in order to facilitate the material box 2 to fall between the L-shaped clamps 31, the upper end of the vertical section of the L-shaped clamp 31 can be set to be inclined outward to form a guide port, and cooperate with the spring to facilitate the material box 2 to fall in and be stable after falling in.

[0021] Lifting bars 41 are located between the concave plate 3 and the horizontal strip, with the length of the top plate 11 being greater than the width of the horizontal strip. The length of the lifting bars 41 is set to at least cover two adjacent top plates 11. When the top of the vertical section of the L-shaped clamp 31 is higher than the bottom of the magazine 2 supported by the top plate 11 on the horizontal strip by a predetermined distance, the top of the vertical section of the L-shaped clamp 31 must also be higher than the top of the vertical section of the concave plate 3. If the top of the vertical section of the concave plate 3 is higher than the top of the vertical section of the L-shaped clamp 31, the top of the vertical section of the L-shaped clamp 31 must also be higher than the bottom of the magazine 2 supported by the top plate 11 on the horizontal strip by a predetermined distance. In this example, the subsequent description assumes that the top of the vertical section of the L-shaped clamp 31 is higher than the top of the vertical section of the concave plate 3. Along the conveying direction, at least a portion of the lifting bars 41 is located in the area corresponding to the magazine placement position, and a portion is located in the area before reaching the magazine placement position. This allows the subsequent magazine 2 to be fed into the magazine placement position and allows the unloaded magazine 2 that is already in the magazine placement position and has completed lead frame discharge to be discharged.

[0022] A groove 12 is provided at the bottom of the top plate 11 and extends along the length direction of the horizontal belt section, for cooperating with the lifting bar 41 to facilitate the transportation of the endless conveyor belt and form a certain guiding and limiting effect.

[0023] During operation, the endless conveyor belt controls the conveying process in a step-by-step manner. When a magazine 2 is loaded onto the magazine placement position, the conveying process is paused, and the lead frames in the previous magazine 2 are delivered before the next one is delivered. In this environment, the operator can now remove the magazine 2 from the magazine placement position in a larger operating space, freeing up space for the operator to perform the operation. That is, the operator can remove the magazine 2 from the magazine placement position at both ends of the horizontal belt body, with one end being used to assemble the magazine 2 onto the top plate 11 and the other end being used to remove the empty magazine 2 from the top plate 11. When the assembled material box 2 moves toward the material box placement position as the top plate 11 is transported by the circular conveyor belt, when it reaches a step position before the material box placement position, the top plate 11 is acted on by the lifting bar 41 to stretch the telescopic rod 1 to lift the material box 2 to a certain height, so that the height of the bottom end of the material box 2 is slightly higher than the top of the vertical section of the L-shaped clamping plate 31, and then the lifting state is maintained, and the circular conveyor belt is transported in a step position, so that the currently lifted material box 2 will cooperate with the top plate 11 and the lifting bar 41 to move When it reaches the next stepping position, that is, the material box placement position, the conveying is suspended, and then the lifting bar 41 is lowered, so that the material box 2 at the material box placement position is lowered and is received on the L-shaped clamping plate 31 to complete the loading; after the material box 2 at the material box placement position is empty, the lifting bar 41 is used to lift the material box 2 again, and the endless conveyor belt is conveyed in one stepping position again, and the empty material box 2 moves to the next stepping position and contacts the support of the lifting bar 41, and the telescopic rod 1 is retracted under the action of the gravity of the top plate 11 and the material box 2. The setting of the lifting bar 41 will not hinder the normal transportation of the material box 2. The vertical cylinder 4 is also located on both sides of the circular conveyor belt and will not block the transportation. The length of the top plate 11 along the width direction of the circular conveyor belt is greater than the width of the circular conveyor belt and smaller than the length of the material box 2 itself in this direction, so that it can be affected by the lifting bar 41, and the material box 2 can be supported by the outer L-shaped clamping plate 31; and when the material box is placed in the position, it will load the material by rising and then falling, and then discharge the material by rising and then conveying and falling, and the whole mechanism can operate normally.

[0024] To ensure better stability of the magazine 2 on the top plate 11, insertion holes can be provided on both sides of the top plate 11, and through holes corresponding to the insertion holes can be provided on both walls of the groove at the bottom of the magazine 2 for inserting fixing pins. By inserting the fixing pins when assembling the magazine 2, the stability during operation is improved. Later, when unloading the empty magazine 2, the fixing pins can be removed before removing the magazine 2.

[0025] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
