Description

Technical Field

[0001] This utility model relates to the field of semiconductor packaging shell processing technology, and in particular to a copper strip roll transfer tool. Background Technology

[0002] The semiconductor packaging housing manufacturing process is divided into lead stamping and lead injection molding, followed by lead cutting. During lead stamping, the raw material used is thin copper or aluminum strip, and the stamping process is continuous, meaning that during operation, the strip is wound into a shape such that... Figure 4 The copper strip shown is placed on the feeding platform, and then fed and stamped under the pull of the stamping equipment. However, during the handling and placement of the copper strip roll on the feeding platform, problems often arise such as the copper strip roll unwinding or unsupported portions sinking. After placement, to ensure the stability of the copper strip transport and prevent folding, operators need to tap the copper strip roll with a wooden stick to ensure that the end faces of the copper strip roll are roughly flat. Additionally, there is the issue of the copper strip roll being difficult to load and place. Utility Model Content

[0003] This utility model provides a copper strip roll transfer fixture to overcome the shortcomings of the prior art, and solves the problems of inconvenient placement of copper strip rolls and uneven end faces of copper strip rolls after placement, thus having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A copper strip roll transfer fixture includes a central column, a placement part at the lower end of the central column, on which the copper strip roll is placed, and a locking part at the upper end of the central column to lock and fix the connection between the placement part and the central column.

[0005] Furthermore, the upper end of the central column is fixed with an upper fixing plate by screws, and a pair of symmetrically arranged upper extension rods are welded to the upper fixing plate. A lifting plate is welded to the upper end of the upper extension rods.

[0006] Furthermore, the placement part includes multiple sleeves welded to the outer periphery of the lower end of the central column, and a lower support bar is inserted into the sleeve.

[0008] Furthermore, an outer protruding plate is welded to the outer periphery of the side plate. A pair of L-shaped rotating arms are rotatably mounted on the outer protruding plate via a shaft. Nuts are threaded to both ends of the shaft. The inner end of the nut abuts against the outer side of the rotating arm. A pressure strip is welded to the inner end of each pair of rotating arms.

[0009] Furthermore, the locking part includes a movable plate movably mounted on the central column. Multiple locking rods are connected to the movable plate by threads. The upper end of the locking rod is provided with an upper cap, which is located on the upper side of the movable plate. The locking rods correspond one-to-one with the pressure strip and the lower support strip. When the locking is fixed, the locking rods are inserted into the pressure strip, the lower support strip, and the locking sleeve.

[0010] Furthermore, a pair of pull rods are movably mounted on the upper fixed plate. An upper pull plate is welded to the upper end of the pull rods, and a spring is sleeved on the pull rods. The lower end of the spring abuts against the upper wall of the movable plate, and the upper end of the spring abuts against the lower wall of the upper fixed plate.

[0011] Furthermore, a protrusion is welded onto the lifting plate, and a hanging rod with a concave structure is inserted through the protrusion. A limit plate is welded to the upper end of the hanging rod.

[0018] Figure 4 A three-dimensional structural diagram of the copper strip coil is shown. Detailed Implementation

[0019] like Figures 1-4 As shown, a copper strip roll transfer fixture includes a central column 1, a placement part at the lower end of the central column 1, on which the copper strip roll is placed, and a locking part at the upper end of the central column 1 to lock and fix the connection between the placement part and the central column 1.

[0020] The upper end of the central column 1 is fixed with an upper fixing plate 4 by screws. A pair of symmetrically arranged upper extension rods 55 are welded on the upper fixing plate 4. A lifting plate 56 is welded to the upper end of the upper extension rods 55.

[0021] The placement part includes multiple sleeves 2 welded to the lower outer periphery of the central column 1, with a lower support bar 3 inserted inside each sleeve 2. The outer end of the lower support bar 3 is bent upward to form a side plate 30, and the inner wall of the side plate 30 constrains the outer periphery of the copper strip coil. An outer protruding plate 31 is welded to the outer periphery of the side plate 30, and a pair of L-shaped rotating arms 34 are rotatably mounted on the outer protruding plate 31 via a shaft 32. Nuts 33 are threaded to both ends of the shaft 32, and the inner ends of the nuts 33 abut against the outer sides of the rotating arms 34. A pressure strip 35 is welded to the inner end of each pair of rotating arms 34.

[0022] The locking mechanism includes a movable plate 51 movably mounted on the central column 1. Multiple insertion rods 53 are threadedly connected to the movable plate 51. Each insertion rod 53 has an upper cap 52 located on the upper side of the movable plate 51. The insertion rods 53 correspond one-to-one with the pressure strip 35 and the lower support strip 3. When the locking mechanism is fixed, the insertion rods 53 are inserted into the pressure strip 35, the lower support strip 3, and the insertion sleeve 2. A pair of pull rods 5 are movably mounted on the upper fixed plate 4. An upper pull plate 50 is welded to the upper end of each pull rod 5. A spring 54 is sleeved on each pull rod 5. The lower end of the spring 54 abuts against the upper wall of the movable plate 51, and the upper end of the spring 54 abuts against the lower wall of the upper fixed plate 4.

[0023] A protrusion 57 is welded onto the lifting plate 56, and a hanging rod 58 with a concave structure is inserted through the protrusion 57. A limit plate is welded to the upper end of the hanging rod 58.

[0024] In this embodiment, during operation, the operator adjusts the processed, wound copper strip from an upright position to a flat position. When placing it, the copper strip is laid flat on a platform with multiple grooves and a central recess. If the copper strip is uneven after being laid flat, it can be tapped to make its end faces flush. Then, the lower end of the central column 1 is placed in the recess, with each insert 2 aligned with each groove. The operator then inserts the lower support strip 3 into the groove until its inner end is inserted into the insert 2, and the inner wall of the side plate 30 abuts against the outer periphery of the copper strip. Finally, the pressure strip 35 is rotated to... The lower wall of the pressure strip 35 abuts against the upper end of the copper strip roll. When performing the above action, the operator needs to pull the upper pull plate 50 upward so that the upper pull plate 50 is close to the pull plate 56, and then move the hanging rod 58 inward so that the outer periphery of the transverse section at the lower end of the hanging rod 58 abuts against the lower wall of the upper pull plate 50. At this time, the spring 54 is in a compressed state. After the pressure strip 35 has rotated, the operator pulls the hanging rod 58 outward so that the lower end of the insertion rod 53 is inserted into the lower support bar 3 and the pressure strip 35. Then, the copper strip roll is placed on the conveyor table, and then the insertion rod 53 is pulled out again, and then the lower support bar 3 is pulled out.
