Description

Technical Field

[0001] The utility model belongs to the technical field of lead frame position adjustment equipment, and in particular relates to a lead frame position calibration device. Background Art

[0002] After the lead frames are stamped, they are stacked together and then output via a conveyor belt. A packaging device is set at the end of the conveyor belt, and the stacked lead frames are vacuum-packed using the packaging device to prevent the lead frames from being deformed during the subsequent packaging process.

[0003] However, during the transportation process, the stacked lead frames will inevitably shift due to factors such as inertia, so when transporting them to the packaging equipment, symmetrical push plates are usually set on the workbench to push the two sides and ends of the lead frames so that the stacked lead frames remain aligned on all sides.

[0004] However, due to the small thickness of the lead frame, the lead frame at the bottom is usually difficult to be pushed by the push plate, or is not pushed into place, resulting in the lead frame at the bottom being unable to maintain alignment with other lead frames, causing deformation during vacuum packaging, wasting molding materials, and high costs. Utility Model Content

[0005] In order to solve the above-mentioned deficiencies in the prior art, the present invention provides a lead frame alignment device, which keeps the edges of the stacked lead frames aligned before vacuum packaging, avoids deformation during the vacuum packaging process, and saves costs.

[0006] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0007] A lead frame alignment device, comprising:

[0008] A set of parallel and spaced conveyor belts is provided for conveying the stacked lead frames. A bagging station is provided at the end of the conveying direction of the set of conveyor belts for vacuum bagging the stacked lead frames. The bagging station is provided with an avoidance groove, the width of which is consistent with the distance between the set of conveyor belts.

[0009] The transfer member is located above the end of a group of conveyor belts in the conveying direction, and includes a vertically arranged telescopic rod. The upper end of the telescopic rod is connected to the transverse movement mechanism, and the lower end is provided with a base plate that is consistent with the length direction of the group of conveyor belts. The two ends of the base plate are respectively provided with a group of L-shaped extraction members with adjustable spacing. The width of the group of extraction members is smaller than the distance between the group of conveyor belts, and is used to lift the stacked lead frames upward;

[0010] The centering parts are respectively arranged on both sides of the ends of a group of conveyor belts in the conveying direction. The centering parts include a bracket with a support rod horizontally passing through the bracket. A push plate is provided at one end of the support rod and a cylinder is provided at the other end for pushing both sides of the stacked lead frame.

[0011] Furthermore, a baffle is provided on one side of the bracket, which is movable along the conveying direction perpendicular to a group of conveyor belts and is used to block the advancement of the lead frame. A slide groove is provided on one side of the bracket, and an adjustment rod is provided on one side of the baffle. The cross-section of the adjustment rod is T-shaped, the vertical part of the adjustment rod is horizontally arranged, and the vertical part of the adjustment rod is slidably connected to the slide groove, which is used to adjust the length of the baffle extending into a group of conveyor belts.

[0012] The beneficial effects of the present invention are:

[0013] A group of extraction members is moved downward to the bottom of a group of conveyor belts, and the vertical parts of the group of extraction members push the two ends of the stacked lead frames to automatically align the two ends of the lead frames. The telescopic rod moves upward, so that the horizontal parts of the group of extraction members lift the stacked lead frames upward from the top of a group of conveyor belts, and the two sides of the group of conveyor belts are used to push the two sides of the stacked lead frames in the middle, so that the two sides of all the stacked lead frames are aligned, thereby avoiding deformation of the bottom layer of lead frames during vacuum packaging and saving costs.

DETAILED DESCRIPTION

[0021] 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.

[0022] like Figure 1-Figure 5 As shown, this embodiment provides a lead frame alignment position, including a group of parallel and spaced conveyor belts 10, a transfer member 20 provided above the end of the conveying direction of the group of conveyor belts 10, and a group of centering members 30 respectively provided on both sides of the end of the conveying direction of the group of conveyor belts 10.

[0023] Specifically, such as Figure 1-Figure 3 As shown, a group of conveyor belts 10 act on both sides of the stacked lead frames 1 respectively, so that the stacked lead frames 1 are conveyed along the length direction of the group of conveyor belts 10 to the end of the group of conveyor belts 10, and a bagging station 11 is provided at the end of the group of conveyor belts 10 for receiving the stacked lead frames 1 transferred by the transfer member 20 and vacuum bagging the stacked lead frames 1.

[0024] The transfer member 20 includes a telescopic rod 21, a seat plate 22, and a group of extraction members 23. The telescopic rod 21 is vertically arranged in the middle position above a group of conveyor belts 10, and the upper end of the telescopic rod 21 is connected to the transverse movement mechanism, which is used to drive the telescopic rod 21 to move back and forth along the length direction of a group of conveyor belts 10. The seat plate 22 is arranged at the lower end of the telescopic rod 21. The seat plate 22 has a long strip structure. The projection of the seat plate 10 on a group of conveyor belts 10 falls between a group of conveyor belts 10, and the length direction of the seat plate 22 is consistent with the length direction of a group of conveyor belts 10. A two-way cylinder is provided on the bottom surface of the seat plate 22, and a group of extraction members 23 are respectively provided at both ends of the two-way cylinder. The distance between a group of extraction members 23 is controlled by the extension and contraction of the output end of the two-way cylinder, so as to adapt to lead frames 1 of different lengths, and the width of a group of extraction members 23 is less than the distance between a group of conveyor belts 10. The bottom surface of the seat plate 22 is provided with a guide groove along the length direction of the seat plate 22. A group of extraction members 23 are L-shaped structures, the upper ends of the vertical parts of which are slidably connected to the guide groove of the seat plate 22, and the horizontal parts of the group of extraction members 23 are arranged oppositely.

[0025] The centering member 30 includes a bracket 31, a support rod 32, and a push plate 33. The bracket 31 is arranged on the outside of the conveying direction of a group of conveyor belts 10. The support rod 32 is arranged to move along the length direction perpendicular to the group of conveyor belts 10. The push plate 33 is arranged at one end of the support rod 32 facing the group of conveyor belts 10.

[0026] During operation, when the stacked lead frames 1 move to the end of the moving direction of a set of conveyor belts 10, a bidirectional cylinder is activated to push a set of extractors 23 along both ends of the base plate 22 toward the ends of the base plate 22, so that the distance between the opposite ends of the transverse portions of the extractors 23 is greater than the length of the stacked lead frames 1. The telescopic rod 21 is then moved vertically downward. When the transverse portions of the extractors 23 move downward below the top surface of the set of conveyor belts 10, the bidirectional cylinder is activated again, causing the bidirectional cylinder to move the extractors 23 toward both ends of the stacked lead frames 1, so that the vertical portions of the extractors 23 push one end of the stacked lead frames 1, thereby neatly stacking them. The telescopic rod 21 then moves upward to a predetermined height. After the extractors 23 vertically lift the lead frames 1 upward, the support rod 32 moves toward the conveyor belts 10, causing the push plates 33 to push the two sides of the stacked lead frames 1, thereby neatly stacking them. Finally, the transverse movement mechanism drives the telescopic rod 21 to move to the bagging table 11. In order to facilitate a group of extraction parts 23 to be taken out from the bottom of the stacked lead frames 1, an avoidance groove 111 is provided on the bagging table 11. The width of the avoidance groove 111 is consistent with the distance between a group of conveyor belts 10. After a group of extraction parts 23 transfers the stacked lead frames 1 to the bagging table 11, a group of extraction parts 23 passes through the avoidance groove 111 vertically downward, so that the stacked lead frames 1 automatically fall onto the bagging table 11, and the two-way cylinder is started to move a group of extraction parts 23 to the two ends of the base plate 22 again, thereby removing the stacked lead frames 1, and finally vacuum bagging is performed.

[0027] Specifically, such as Figure 3-Figure 5 As shown, a baffle 34 is provided on the side of the bracket 31 facing the end of the conveying direction of a group of conveyor belts 10. The baffle 34 is movable along the conveying direction perpendicular to the conveying direction of a group of conveyor belts 10 to block the advancement of the lead frame 1 to prevent the stacked lead frame 1 from flying out due to inertia. A slide groove 311 is provided on the side of the bracket 31 facing the end of the conveying direction of a group of conveyor belts 10. The slide groove 311 passes through both sides of the bracket 31. An adjusting rod 341 is provided on the side of the baffle 34 facing the bracket 31. The cross-section of the adjusting rod 341 is T-shaped. The vertical part of the adjusting rod 341 is horizontally arranged, and the horizontal part is connected to one end of the baffle 34. The vertical part of the adjusting rod 341 is slidably connected to the slide groove 311 to adjust the length of the baffle 34 extending into the group of conveyor belts 10 to accommodate lead frames 1 of different widths.

[0028] Specifically, such as Figure 2As shown, the bracket 31 is an inverted U-shaped structure, and a group of support rods 32 are arranged at intervals. A connecting plate 35 is provided at the end of the support rod 32 away from a group of conveyor belts 10. The bottom surface of the middle part of the connecting plate 35 is rotatably connected to the upper end of the rotating rod 36. A cylinder 37 is provided just below the end of the conveying direction of a group of conveyor belts 10. The output end of the cylinder 37 is vertically upward, and a cross plate 371 is provided at its output end. Connecting seats 372 are respectively provided at both ends of the cross plate 371, and the connecting seats 372 are respectively rotatably connected to the lower ends of the corresponding rotating rods 36.

[0029] Specifically, such as Figure 3 、 Figure 5 As shown, a connection groove 342 is provided on one side of the vertical portion of the adjustment rod 341 , and a fastening bolt 312 is vertically provided on one end of the horizontal portion of the bracket 31 facing the adjustment rod 341 for connection with the connection groove 342 .
