Technical Field

[0001] The invention belongs to the technical field of lead frame stacking, and in particular relates to a lead frame stacking support frame structure. Background Art

[0002] Lead frame is a component of the metal lead that runs through the circuit board in electronic devices or circuit boards. It plays an important role in electronic devices and circuit boards. It can connect the various components in electronic devices or circuit boards to complete the transmission and control of the circuit. It is an important part of electronic devices. The materials used to make lead frames are different. For example, tin-plated or lead-plated copper lead frames have good conductivity and are easy to process, but their materials are relatively soft and prone to deformation and wear.

[0003] At present, during the transportation process of lead frames after production, the lead frames are stacked on the support frame. However, in the existing lead frame stacking support frame structure, the lead frame is prone to relative sliding with the support frame, causing the lead frame made of softer material to wear and deform, resulting in degradation of lead frame performance, and the lead frame may be offset when stacked, resulting in uneven stacking of the lead frame, which may cause the stacked lead frame to fall over and damage the lead frame.

[0004] Therefore, based on the above problems, we designed a lead frame stacking support frame structure. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a lead frame stacking support frame structure, which solves the technical problems of the existing lead frame stacking support frame structure, that is, the lead frame is prone to relative sliding with the support frame, causing the lead frame made of a relatively soft material to wear and deform, resulting in a decrease in the performance of the lead frame, and that when the lead frames are stacked, they may deviate, resulting in uneven stacking of the lead frames, thereby causing the stacked lead frames to fall over and damage the lead frames.

[0006] To achieve the above object, an embodiment of the first aspect of the present invention provides a lead frame stacking support frame structure, comprising a support frame frame, a pair of side plates arranged in the support frame frame, and a plurality of mounting rods arranged on the inner wall of each mounting side plate;

[0007] Also includes:

[0009] A sliding seat is arranged on the side of the supporting frame, an electric push rod is arranged on the sliding seat, a flat pull plate is connected to the end of the electric push rod, and an adsorption magnetic block 1 is arranged in the middle of the flat pull plate;

[0010] Wherein, a second adsorption magnetic block is arranged on one side of the surface of each stacking plate at a position corresponding to the first adsorption magnetic block.

[0011] A further improvement is that a plurality of evenly distributed clamping holes are provided on the surface of each stacking plate, and a plurality of rubber clamping heads are provided along the edge of the bottom surface of each anti-drop clamping frame.

[0012] A further improvement is that a pad for placing the lead frame is arranged in the port of each anti-drop card frame, and a protective film is arranged on the surface of each pad and the inner wall of the anti-drop card frame.

[0013] A further improvement is that a slide groove is provided on the surface of each mounting rod, one side of the slide groove extends out, and two sides of each stacking plate are bent and slidably clamped in the slide groove.

[0014] A further improvement is that it also includes several brackets, which are respectively arranged in the two side ports of the support frame, a compression spring is arranged between the surface of each bracket and the inner wall of the support frame, and a guide wheel is rotatably arranged at the end of each bracket.

[0015] A further improvement is that a triangle is formed between each of the compression springs, the bracket and the support frame.

[0016] A further improvement is that grooves for installing guide wheels are provided on both sides of the surface of each stacking plate.

[0017] A further improvement is that a base is provided on the side of the support frame, a reciprocating screw is provided in the port of the base, a thread groove is provided in the middle of the sliding seat, and the thread groove of the sliding seat is sleeved on the reciprocating screw.

[0018] A further improvement is that a limit rod is arranged inside the port of the base on the side of the reciprocating screw, the sliding seat is movably sleeved on the limit rod, and the reciprocating screw is driven by a servo motor externally arranged on the base.

[0019] A further improvement is that scales are provided on both sides of the surface of the base, and the inner wall of the sliding seat is in contact with the surface of the scales.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The present invention realizes convenient assembly by clamping the rubber clamp head on the bottom surface of the anti-drop clamp frame into the clamp hole of the stacking plate. At this time, the anti-drop clamp frame that can accommodate lead frames of different sizes but the same model can be installed on each layer of the stacking plate, and multiple models of lead frames can be placed in a limited position, which has a wider application range and higher transportation efficiency;

[0022] (2) The present invention slides both sides of each stacking plate into the slide grooves on the surfaces of two equal-height mounting rods, and moves the lifting bracket and the guide wheel so that the guide wheels are respectively placed in the grooves on the surfaces of the stacking plates. At this time, the bracket compresses the compression spring, so that the compression spring generates a rebound force after deformation. When the entire support frame structure moves and transports, the guide wheel of each layer is used to press the edge of the stacking plate, which can effectively prevent the stacking plate from sliding out without manual locking;

[0023] (3) The present invention can protect the bottom surface and edge of the lead frame by placing the lead frame on the pads in the port of the anti-drop card frame and contacting the surface of each pad and the protective film in the anti-drop card frame. The lead frame is not easily offset and can effectively avoid abnormal wear and deformation of the lead frame, thereby ensuring the performance of the lead frame.

[0024] (4) The present invention drives the reciprocating screw to rotate by a servo motor, and drives the sliding seat, the electric push rod and the flat pull plate to rise and fall together until they are adjusted to the layer, and then drive them to retract by the electric push rod. When the rod body retracts, the adsorption magnetic block 1 on the flat pull plate and the adsorption magnetic block 2 on the side of the stacking plate of the layer are adhered to each other, and push the stacking plate out together with the lead frame; after the lead frame is placed, the electric push rod is repeatedly operated to drive it to extend. When the rod body is extended, the adsorption magnetic block 1 and the adsorption magnetic block 2 are used to allow the flat pull plate to pull the stacking plate into the support frame until the side of the stacking plate is against the end of the slide slot. When the rod body continues to extend, the adsorption magnetic block 1 and the adsorption magnetic block 2 are separated, which can facilitate the removal of the lead frame at a later time.

[0033] The technical scheme of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1 As shown, a lead frame stacking support frame structure includes a support frame frame 2, a pair of side plates 1 arranged in the support frame frame 2, and a plurality of mounting rods 11 arranged on the inner wall of each mounting side plate 1;

[0035] like Figure 2 , Figure 5 and Figure 6 As shown, the implementation includes: a plurality of stacking plates 3, which are respectively arranged on two mounting rods 11 of equal height, and a plurality of anti-dropping card frames 4 are arranged on the surface of each stacking plate 3;

[0036] Specifically, a plurality of evenly distributed card holes 31 are provided on the surface of each stacking plate 3, a plurality of rubber card heads 41 are provided along the edge of the bottom surface of each anti-drop card frame 4, a pad 42 for placing the lead frame is provided in the port of each anti-drop card frame 4, and a protective film 43 is provided on the surface of each pad 42 and the inner wall of the anti-drop card frame 4. By clamping the rubber card heads 41 on the bottom surface of the anti-drop card frame 4 in the card holes 31 of the stacking plate 3, convenient assembly is achieved. At this time, an anti-drop card frame 4 that can accommodate lead frames of different sizes but the same model can be installed on each layer of stacking plates 3, so that multiple lead frames of different models can be placed, and the application range is wider; the lead frames are respectively placed on the pads 42 in the ports of the anti-drop card frames 4, and are in contact with the surface of each pad 42 and the protective film 43 in the anti-drop card frame 4, so as to protect the bottom surface and edges of the lead frames, and effectively avoid abnormal wear and deformation of the lead frames;

[0037] Specifically, a slide groove 12 is provided on the surface of each mounting rod 11, one side of the slide groove 12 extends out, and both sides of each stacking plate 3 are bent and slidably stuck in the slide groove 12, and the slide groove 12 is used for the limited sliding of the stacking plate 3;

[0038] like Figure 5 As shown, the implementation includes: a plurality of brackets 22, which are respectively arranged in the ports on both sides of the support frame 2, a compression spring 23 is arranged between the surface of each bracket 22 and the inner wall of the support frame 2, and a guide wheel 21 is rotatably arranged at the end of each bracket 22;

[0039] Among them, a triangle is formed between each compression spring 23, the bracket 22 and the support frame 2, and grooves 32 for installing the guide wheel 21 are opened on both sides of the surface of each stacking plate 3. When the bracket 22 and the guide wheel 21 are raised, the guide wheel 21 is respectively placed in the grooves 32 on the surface of the stacking plate 3. At this time, the bracket 22 compresses the compression spring 23, so that the compression spring 23 generates a rebound force after deformation. When the entire support frame structure is moved and transported, the guide wheel 21 of each layer is used to press the edge of the stacking plate 3, which can effectively prevent the stacking plate 3 from sliding out without manual locking;

[0040] like Figure 3 and Figure 4 As shown, the implementation includes: a sliding seat 5, which is arranged on the side of the support frame 2, and an electric push rod 51 is arranged on the sliding seat 5. The end of the electric push rod 51 is connected to a flat pull plate 52, and an adsorption magnetic block 1 53 is arranged in the middle of the flat pull plate 52. An adsorption magnetic block 2 55 is arranged on one side of the surface of each stacking plate 3 at a position corresponding to the adsorption magnetic block 1 53;

[0041] Specifically, a base 54 is provided on the side of the support frame 2, a reciprocating screw 56 is provided in the port of the base 54, a threaded groove is provided in the middle of the sliding seat 5, the threaded groove of the sliding seat 5 is sleeved on the reciprocating screw 56, a limit rod 57 is provided on the side of the reciprocating screw 56 in the port of the base 54, the sliding seat 5 is movably sleeved on the limit rod 57, the reciprocating screw 56 is driven by a servo motor 58 externally arranged on the base 54, the servo motor 58 drives the reciprocating screw 56 to rotate, and drives the sliding seat 5, the electric push rod 51 and the flat pull plate 52 to rise and fall together, until they are adjusted to the layer, and then the electric push rod 51 is used to move the reciprocating screw 56 to the horizontal pull plate 52. The rod 51 is driven to retract. When the rod body retracts, the adsorption magnetic block 1 53 on the flat pull plate 52 and the adsorption magnetic block 2 55 on the side of the stacking plate 3 of the same layer adhere to each other, so that the stacking plate 3 can be pushed out together with the lead frame; and after the lead frame is placed, the electric push rod 51 is repeatedly operated to drive the extension. When the rod body is extended, the adsorption magnetic block 1 53 and the adsorption magnetic block 2 55 are used to make the flat pull plate 52 pull the stacking plate 3 into the support frame 2 until the side of the stacking plate 3 is against the end of the slide groove 12. When the rod body continues to extend, the adsorption magnetic block 1 53 and the adsorption magnetic block 2 55 are separated, so that the lead frame can be easily taken out.

[0042] like Figures 1 to 6As shown, in this embodiment, scales 59 are further provided on both sides of the surface of the base 54, and the inner wall of the sliding seat 5 is in contact with the surface of the scale 59. The scale 59 is used to observe the height and facilitate adjustment to a suitable height.

[0043] During the implementation of this embodiment, it should be noted that the actual size of each component in the application document is selected and installed before implementation according to the actual needs on site. Before implementation, a pick-up groove 44 is pre-opened on the surface of each anti-drop card frame 4. After the lead frame is placed on the pad 42 inside the anti-drop card frame 4, when it is needed, the two sides of the lead frame can be lifted out from the pick-up groove 44. In addition, it should be noted that the electric push rod 51 and the servo motor 58 are both commercially available products of the prior art, and the working principle has been disclosed. This application document only targets the existing lead frame stacking support frame structure. The lead frame is prone to relative sliding with the support frame, causing the lead frame of the softer material to wear and deform, resulting in a decrease in the performance of the lead frame, and may deviate when stacking the lead frame, resulting in uneven stacking of the lead frame, thereby causing the stacked lead frame to fall over and cause damage to the lead frame. The shortcomings are improved, and no other aspects are involved; the working principle of this lead frame stacking support frame structure is introduced as follows:

[0044] During installation, the on-site personnel select the anti-drop card frame 4 of the appropriate size according to the lead frames of different batches, and then clamp the rubber clamp head 41 on the bottom of the anti-drop card frame 4 into the clamp hole 31 of the stacking plate 3 to achieve convenient assembly. At this time, the anti-drop card frame 4 that can accommodate lead frames of different sizes but the same model can be installed on each layer of the stacking plate 3;

[0045] Then, the two sides of each stacking plate 3 are slid and clamped in the slide grooves 12 on the surfaces of the two equal-height mounting rods 11, and the lifting bracket 22 and the guide wheel 21 are moved, so that the guide wheel 21 is respectively placed in the grooves 32 on the surface of the stacking plate 3. At this time, the bracket 22 compresses the pressing spring 23, so that the pressing spring 23 generates a rebound force after deformation, and the overall assembly is completed;

[0046] When the lead frame needs to be placed on the stacking plate 3 of the layer, the servo motor 58 drives the reciprocating screw 56 to rotate, and drives the sliding seat 5, the electric push rod 51 and the flat pull plate 52 to rise and fall together, until it is adjusted to the layer, and then driven to retract by the electric push rod 51. When the rod body retracts, the adsorption magnetic block 1 53 on the flat pull plate 52 and the adsorption magnetic block 2 55 on the side of the stacking plate 3 of the layer adhere to each other, and push the stacking plate 3 out together with the lead frame;

[0047] Then, the on-site personnel place the lead frames on the pads 42 in the ports of the anti-drop card frame 4, respectively, and contact the surfaces of each pad 42 and the protective film 43 in the anti-drop card frame 4, so as to protect the bottom surface and edges of the lead frames, and effectively prevent abnormal wear and deformation of the lead frames; After the lead frames are placed, the electric push rod 51 is repeatedly operated to drive the extension. When the rod body is extended, the adsorption magnetic block 1 53 and the adsorption magnetic block 2 55 are used to allow the flat pull plate 52 to pull the stacking plate 3 into the support frame 2 until the side of the stacking plate 3 is against the end of the slide groove 12. When the rod body continues to extend, the adsorption magnetic block 1 53 and the adsorption magnetic block 2 55 are separated, completing the convenient removal and placement of the lead frames on the layer;

[0048] When the entire support frame structure is moved and transported, the guide wheel 21 of each layer is used to press the edge of the stacking plate 3, which can effectively prevent the stacking plate 3 from sliding out without manual locking. The design of the present invention can limit the placement of multiple models of lead frames, has a wider range of applications, and is not prone to offset. The lead frames are stacked more neatly, which is convenient for later removal of the lead frames and has higher transportation efficiency. It can protect the bottom surface and edges of the lead frames, avoid wear and deformation of lead frames made of softer materials, thereby ensuring the performance of the lead frames.

[0049] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
