Description

Technical Field

[0001] This application relates to the field of semiconductor packaging technology, and in particular to a lead frame transfer loading vehicle. Background Technology

[0002] During semiconductor device packaging, lead frames are cleaned and dried before being transported to designated stations for operations such as core bonding and wire bonding. This process involves the transfer of lead frames. Generally, lead frames are transferred using a tin box, but manual unloading is still required if tin box unloading is used, so improvements are necessary. Utility Model Content

[0003] To address the shortcomings of the prior art, this application provides a lead frame transfer and loading vehicle that can perform both transfer and auxiliary loading functions, and improves the stability of lead frame transfer.

[0004] To achieve the above objectives, the present invention employs the following technology: A lead frame transfer and loading vehicle includes: The base plate has a side plate vertically mounted on one end and multiple casters mounted below it. The placement box is vertically movable on the base plate, and multiple placement slots are vertically arrayed on it. Each placement slot is through-hole and rotatably equipped with a baffle. The rotation axis of the baffle is parallel to the width direction of the placement slot, and sliding grooves are provided on both ends of the baffle. Multiple movable blocks, each corresponding to a placement slot, are located between the side panel and the placement box. Both ends of the movable blocks are horizontally connected to support rods, and the ends of the support rods pass vertically through the placement box to form through rods. The through rods slide through the corresponding sliding slots. The adjusting component and the push plate are both set at a predetermined height and located between the side plate and the movable block. The adjusting component is used to act on the movable block to open the baffle. The push plate is moved along the length of the placement slot. The placement slots all pass through the inner end face of the placement box and have a first clearance slot. The movable blocks all pass through and have a second clearance slot. The first clearance slot and the second clearance slot correspond one-to-one and are both matched with the push plate.

[0005] The advantages of this invention are that it not only improves the stability and safety of the lead frame during transfer, but also has the functions of transfer and auxiliary feeding, making it highly practical. Attached Figure Description

[0012] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0013] This application provides a lead frame transfer and loading vehicle, such as... Figures 1-5 As shown, it includes a base plate 1, a placement box 3, multiple movable blocks 4, an adjusting component, and a push plate 5.

[0014] A side plate 2 is vertically provided at one end of the base plate 1, and multiple casters 6 are provided at the bottom of the base plate 1 for easy movement.

[0015] The placement box 3 is vertically moved and mounted on the base plate 1. Multiple placement slots 31 are arranged vertically along the upper edge of the placement box 3. Each placement slot 31 has a through-hole on its outer end and a baffle 32 is rotatably provided. The outer end is the end of the placement slot 31 that is away from the side plate 2. The rotation axis of the baffle 32 is parallel to the width direction of the placement slot 31. Both ends of the baffle 32 have a sliding groove 321 along its own width direction.

[0016] Multiple movable blocks 4 are located between the side plate 2 and the placement box 3 and correspond one-to-one with the placement groove 31. The movable blocks 4 are arranged parallel to the width direction of the placement groove 31. Both ends of the movable blocks 4 are horizontally connected to support rods 41. The ends of the support rods 41 pass vertically through the placement box 3 and form through rods. The through rods slide through the corresponding sliding grooves 321.

[0017] Both the adjusting member and the push plate 5 are located at a predetermined height between the side plate 2 and the movable block 4. The adjusting member acts on the movable block 4 to open the baffle 32. The push plate 5 is movable along the length of the placement groove 31. The placement groove 31 is provided with a first clearance groove 33 through the inner end face of the placement box 3. The movable block 4 is provided with a second clearance groove 42 through the inner end face of the placement box 3. The first clearance groove 33 and the second clearance groove 42 correspond one-to-one and are both matched with the push plate 5. In this embodiment, the push plate 5 can be driven to move by a cylinder, which is fixedly installed on the side plate 2.

[0018] In application, by moving the placement box 3 up and down, multiple movable blocks 4 can sequentially engage with the adjusting component, and under the sliding engagement of the through rod and the slide groove 321, the baffle 32 rotates outward to the open state. At this time, the operator can push the lead wire frame into the corresponding placement groove 31. After all the frames are placed, the device is transferred to the loading station by the casters 6. Again, by moving the placement box 3 up and down, multiple movable blocks 4 can sequentially engage with the adjusting component, causing the baffle 32 to open. At this time, the push plate 5 is used to push out the lead wire frame in the corresponding placement groove 321 for more convenient loading. The loading station can be connected to the conveyor belt to complete subsequent production.

[0019] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, slide rods 34 are slidably passed through both ends of the movable block 4. The slide rods 34 are connected to the inner end face of the placement box 3 and are parallel to the length direction of the placement groove 31. Springs 35 are sleeved around the slide rods 34 and are located between the placement box 3 and the movable block 4.

[0020] More specifically, such as Figures 3-5 As shown, the adjusting component includes two rollers 7 symmetrically arranged at both ends of the push plate 5. Each roller 7 is rotatably mounted on a support extending from the side plate 2. The axis of rotation of the roller 7 is parallel to the width direction of the placement groove 31. The movable block 4 has an arc-shaped segment 43 facing the side plate 2 that corresponds to the roller 7. When the highest point of the arc-shaped segment 43 of one of the movable blocks 4 abuts against the roller 7, the first clearance groove 33 and the second clearance groove 42 on it correspond to the position of the push plate 5, and the movable block 4 moves to the predetermined outermost end to open the baffle 32. In use, the lifting and lowering of the placement box 3 will cause multiple movable blocks 4 to engage with the adjusting component in sequence. Taking one of the movable blocks 4 as an example, the specific engagement process is as follows: During the process of the movable block 4 moving to the predetermined height, the roller 7 and its arc-shaped segment 43 slide to engage, so that the movable block 4 moves along the length direction of the placement groove 31 and away from the side plate 2. The spring 35 is in a compressed state, so under the sliding engagement of the through rod and the slide groove 321, the baffle 32 rotates outward. When the highest point of the arc-shaped segment 43 abuts against the roller 7, the baffle 32 is in an open state to facilitate the entry and exit of the lead frame.

[0021] Specifically, such as Figure 1 and Figure 3 As shown, the height difference between the adjusting component / push plate 5 and the base plate 1 is greater than the height of the placement box 3, ensuring that when the bottom surface of the placement box 3 contacts the top surface of the base plate 1, the adjusting component does not engage with any of the movable blocks 4, and the baffles 32 are all in the closed state under the action of the spring 35, so as to ensure stability during transfer.

[0022] Specifically, such as Figure 1As shown, the placement box 3 has mating parts 36 formed on both sides facing outward. One mating part 36 is threaded onto a screw 11, and the other mating part 36 is slidably mounted onto a guide rod. Both the screw 11 and the guide rod are vertically mounted on the base plate 1. In this embodiment, the screw 11 is driven to rotate by a motor, which is fixedly mounted on the base plate 1.

[0023] In application, the above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
