Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic device housing processing technology, and in particular to a material tray for punching copper strips for leads. Background Technology
[0002] The main body of the electronic device housing is a plastic shell with multiple pins on both sides. The pins are formed by stamping on a copper strip. When connecting the pins to the plastic shell, the formed pins are first placed in a curing mold, and then the housing is formed and the two are connected by injection molding.
[0003] The copper strip used for pin punching is often wound into rolls, and to prevent corrosion or oxidation from air or the environment, it is usually effectively sealed and packaged. During transport, it is typically placed on a rotating disc, which rotates along with the copper strip. Using this method, firstly, the copper strip is prone to relative movement to the rotating disc due to the tension, which can easily damage it. Secondly, since the copper strip and the rotating disc rely heavily on friction to maintain synchronization, if the copper strip feed speed increases and the rotating disc speed becomes too high, the friction may be insufficient to keep the copper strip and the rotating disc rotating synchronously, resulting in centrifugal motion and affecting the normal feeding of the copper strip. Utility Model Content
[0004] This utility model provides a material tray for punching copper strip to overcome the shortcomings of the prior art. It can limit the two ends of the copper strip roll to avoid damage to the copper strip during transportation, and facilitates the fixing of the copper strip, thus having strong practicality.
[0005] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:
[0006] A lead-punching copper strip material tray includes a vertical plate with a bearing seat mounted on it. The bearing seat is connected to a rotating shaft via a key, and a turntable is mounted on the other end of the rotating shaft. Multiple pairs of strip holes are arranged in a circumferential array on the turntable. Movable screws are movably installed in the strip holes. Each pair of movable screws is connected to a movable plate via a thread. A pair of side plates are bent into shape on the movable plate. End grooves are opened on the side plates. The inner end of the end groove is connected to a push groove. There is an angle between the length direction of the push groove and the length direction of the end groove, and the length direction of the end groove is perpendicular to the length direction of the strip holes.
[0007] A push rod is movably mounted within the end slot and the push groove. A connecting arm is rotatably mounted on the push rod. A push plate is mounted on the inner end of the connecting arm via screws. A rotating shaft passes through the push plate. An inner top plate is threaded onto each pair of movable screws. The inner top plate acts on the inner wall of the copper strip coil to fix the copper strip coil. A rotating seat is coaxially mounted on the other side of the turntable via screws. This rotating seat can be a ring fixed to the turntable by screws. A bearing is installed inside the ring, and the adjusting screw is connected to the inner ring of the bearing via a key. An adjusting screw is rotatably mounted on the rotating seat. A handle is provided on the outer end of the adjusting screw. An inner top plate is threaded onto the adjusting screw. Multiple push-pull connecting rods are threaded onto the inner top plate. The other end of the push-pull connecting rods is threaded onto the push plate. In application, the rotation of the adjusting screw can drive the inner top plate to move inward. During the inward movement, the push-pull connecting rod will drive the push plate to move, and the movement of the push plate will drive the push rod on it to move, so that the push rod acts on the push groove, thereby causing the movable plate and the inner top plate to move outward. This allows the inner top plate to act on the inner circle of the copper strip coil, thereby achieving the purpose of positioning the copper strip. The outstanding feature of this fixing method is that after fixing, the center of the copper coil is basically concentric with the center of the turntable, and the fixing stability is relatively strong.
[0008] Furthermore, to limit the other end of the copper coil, multiple protruding plates are formed on the outer periphery of the inner top plate, with a limiting outer plate hinged to the outer end of each protruding plate. A rotating sleeve is welded to the outer end face of the inner top plate, and a rotating ring is rotatably mounted on the rotating sleeve. Multiple limiting baffles are provided on the outer periphery of the rotating ring, with the inner wall of the limiting baffles acting on the outer wall of the limiting outer plate. This design also facilitates the placement of the copper strip coil on the inner top plate.
[0009] Furthermore, in order to facilitate the limiting of the baffle, an L-shaped plate is welded on the outer wall of the limiting outer plate, and the outer end of the limiting baffle is located between the inner wall of the L-shaped plate and the outer wall of the limiting outer plate.
[0010] Furthermore, in order to limit the rotation ring, a limit nut is threadedly connected to the rotation sleeve, and the inner end of the limit nut acts on the outer wall of the rotation ring.
[0011] Furthermore, in order to limit the movement of the outer limiting plate and the inner top plate, a middle ring is installed on the turntable by screws. The middle ring has multiple notches, and the outer limiting plate is located in the notches.
[0012] The advantages of the above technical solution are:
[0013] This invention can limit the two ends of the copper strip roll and stably fix the copper strip roll, thereby ensuring the stability of the copper strip during transportation. Attached Figure Description

[0018] Figure 4 A magnified view of point A is shown. Detailed Implementation
[0019] like Figures 1-4 As shown, a lead-punching copper strip material tray includes a vertical plate 1, on which a bearing seat is mounted. The bearing seat is connected to a rotating shaft 2 via a key. A turntable 3 is mounted on the other end of the rotating shaft 2. The turntable 3 has multiple pairs of strip-shaped holes 30 arranged in a circumferential array. Movable screws 31 are movably installed in the strip-shaped holes 30. Each pair of movable screws 31 is threadedly connected to a movable plate 32. A pair of side plates 33 are bent and formed on the movable plate 32. End grooves 35 are opened on the side plates 33. The inner end of the end groove 35 is connected to a push groove 34. There is an angle between the length direction of the push groove 34 and the length direction of the end groove 35, and the length direction of the end groove 35 is perpendicular to the length direction of the strip-shaped holes 30. A push rod 38 is movably installed in the end groove 35 and the push groove 34. A connecting arm 37 is rotatably installed on the push rod 38. A push plate 36 is installed on the inner end of the connecting arm 37 via screws. The rotating shaft 2 passes through the push plate 36. Each pair of movable screws 31 is threadedly connected to an inner top plate 39, which acts on the inner wall of the copper strip coil to fix it. On the other side of the turntable 3, a rotating seat is coaxially mounted with screws. An adjusting screw 4 is rotatably mounted on the rotating seat. A handle 40 is provided on the outer end of the adjusting screw 4. An inner top plate 41 is threadedly connected to the adjusting screw 4. Multiple push-pull connecting rods 61 are threadedly connected to the inner top plate 41. The other end of the push-pull connecting rods 61 is threadedly connected to the push plate 36.
[0020] Multiple protruding plates 42 are formed on the outer periphery of the inner top plate 41, and a limiting outer plate 44 is hinged to the outer end of the protruding plate 42. A rotating sleeve 47 is welded to the outer end face of the inner top plate 41, and a rotating ring 49 is rotatably mounted on the rotating sleeve 47. Multiple limiting baffles 50 are provided on the outer periphery of the rotating ring 49, and the inner wall of the limiting baffle 50 acts on the outer wall of the limiting outer plate 44. An L-shaped plate 46 is welded to the outer wall of the limiting outer plate 44, and the outer end of the limiting baffle 50 is located between the inner wall of the L-shaped plate 46 and the outer wall of the limiting outer plate 44. A limiting nut 48 is threadedly connected to the rotating sleeve 47, and the inner end of the limiting nut 48 acts on the outer wall of the rotating ring 49. A middle ring 6 is installed on the turntable 3 by screws, and multiple notches 60 are opened on the middle ring 6. The limiting outer plate 44 is located within the notches 60.
[0021] Before operation, the tray in this embodiment is generally in the following state: the outer limiting plate 44 is horizontal and the inner top plate 39 is in a retracted state.
[0022] In this embodiment, during operation, the operator first places the copper strip roll on the inner top plate 39, and there is a certain gap between the inner end of the copper strip roll and the turntable 3.
[0023] The operator rotates the adjusting screw 4 using the handle 40 or with the help of appropriate tools. When the adjusting screw 4 rotates, it will drive the inner top plate 41 to move inward. Of course, the limiting outer plate 44 on it will also move inward. As the inner top plate 41 moves, it will drive the push plate 36 on it to move through the push-pull connecting rod 61. As the push plate 36 moves, it will move through the push rod 38 on it. During the movement of the push rod 38, it will act on the push groove 34, thereby causing the movable plate 32 and the inner top plate 39 connected to it to move outward, so as to achieve the purpose of supporting and fixing the inside of the copper strip coil through the inner top plate 39.
[0024] Then, the operator rotates the limiting outer plate 44 upwards to make the limiting outer plate 44 vertical. After rotation, the flexible inner plate 45 on the limiting outer plate 44 will act on the outer end of the copper strip coil, and achieve the purpose of limiting the outer side of the copper strip coil. Then, the rotating ring 49 is rotated so that the inner wall of the limiting baffle 50 acts on the outer wall of the limiting outer plate 44, thereby preventing the limiting outer plate 44 from rotating, and then the copper strip is conveyed.

Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
