[0002] After the lead frame is welded, contaminants such as flux, oxides, and dirt will remain on its surface. To avoid affecting the quality of the packaged product during subsequent packaging, it is necessary to first clean the lead frame to remove the contaminants on its surface.

[0003] The existing cleaning method is to horizontally insert the lead frames into the cartridge in sequence and keep a predetermined distance between the lead frames to avoid interference of the protrusions on adjacent two lead frames. Then, hold both ends of the cartridge and vertically place the cartridge with the lead frames into the cleaning tank for ultrasonic cleaning. After cleaning, lift it out vertically upward.

[0004] During this process, since the cartridge and the lead frames remain stationary, the cleaned contaminants are likely to deposit on the lower-layer lead frames, affecting the cleaning effect. And after cleaning, it is necessary to put them into the next cleaning tank one by one to remove the excess cleaning liquid on their surfaces, and then lift them out one by one, which is cumbersome to operate. Summary of the Utility Model

[0005] To solve the above deficiencies of the existing technology, the utility model provides a cartridge transfer device, which can transfer the cartridges in batches and improve the cleaning effect of the lead frames, and avoid the deposition of contaminants on the lower-layer lead frames.

Detailed implementation mode

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will describe the implementation modes of the present utility model in detail with reference to the accompanying drawings. However, the embodiments described herein are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0026] As Figures 1-6 shown, this embodiment provides a cartridge transfer device, which includes a loading frame 10 for loading the cartridge 1 containing the lead frame to be cleaned. The lower ends of the connecting members 20 are respectively connected to both ends of the loading frame 10, and the upper ends are connected to the transverse movement mechanism for transferring the loading frame 10 with the cartridge 1. A set of flipping assemblies 30 are provided and are respectively installed on the connecting members 20. One end of the flipping assembly 30 is connected to the loading frame 10 for driving the loading frame 10 to rotate, so that the lead frame in the cartridge 1 can be better cleaned, and at the same time, it is convenient for the pollutants after cleaning to fall out of the cartridge 1, improving the cleaning efficiency.

[0027] Specifically, the loading frame 10 includes a frame body 11. Ribs 111 protruding inward are provided around the inner wall of the frame body 11 for limiting the periphery of the cartridge 1 and one end of the lead frame installed in the cartridge 1 to prevent the cartridge 1 and the lead frame 1 from moving when rotating and falling out of the frame body 11. An opening 112 is provided on one side of the frame body 11 for the cartridge 1 to enter the frame body 11 along the width direction of the frame body 11. A side plate 12 is hinged on one side of the opening 112 for limiting the outer wall of the cartridge 1 facing the opening and the other end of the lead frame. Locking fasteners 13 are provided at both ends of the bottom of the frame body 11 on the side with the opening 112 for connecting both ends of one side of the side plate 12, thereby locking the side plate to one side of the frame body 11.

[0028] The connecting member 20 includes a telescopic rod 21 and a U - shaped frame 22. The U - shaped frame 22 is arranged upside down. The lower end of the telescopic rod 21 is connected to the upper end of the horizontal part of the U - shaped frame 22, and the upper end of the telescopic rod 21 is connected to the transverse movement mechanism for driving the telescopic rod 21 to move horizontally. The vertical parts of the U - shaped frame 22 are vertically downward and are respectively rotatably connected to both ends of the frame body 11 to drive the loading frame 10 to move synchronously.

[0029] The flipping assembly 30 includes a gear 31, a rack 32, and a cylinder 33. The gear 31 is provided at one end of the frame 11 and is connected to one end of the frame 11 through a rotating shaft passing through the vertical part of the U-shaped frame 22. The rack 32 is vertically arranged and meshes with the gear 31. The cylinder 33 is provided outside the vertical part of the U-shaped frame 22, and the output end of the cylinder 33 is connected to the upper end of the rack 32.

[0030] The specific operation process is as follows:

[0031] Open the side plate 12, place the cartridge containing the lead frame 1 along the width direction of the frame 11, and then use the locking fastener 13 to lock the two ends of the non-hinged side of the side plate 12 to the frame 11.

[0032] Start the telescopic rod 21 to move vertically upward, so that the telescopic rod 12 moves to directly above the cleaning tank under the action of the transverse movement mechanism. Start the telescopic rod 12 again to move vertically downward, so that the frame 11 containing the cartridge 1 is immersed in the cleaning liquid, and start the cylinder 33 to drive the rack 32 to move synchronously, so that the rack 32 drives the gear 31 to rotate, thereby driving the carrier frame 10 to rotate, accelerating the flow of the cleaning liquid, improving the cleaning efficiency, and at the same time accelerating the shedding of pollutants from the lead frame, improving the cleaning efficiency.

[0033] Preferably, in order to increase the storage capacity of the cartridge 1, the frame 11 is set as a cuboid structure, the inner wall length of the frame 11 is an integer multiple of the width of the cartridge 1, and the cartridges 1 are placed in the frame 11 in sequence along the length direction of the frame 11. The outer walls of the cartridges 1 at both ends are limited by the inner walls on both sides of the frame 11, and the opposite outer walls of adjacent cartridges 1 are in contact with each other. Reinforcing ribs 115 are provided on both the top and bottom of the frame 11 to improve the stability of the frame 11.

[0034] Specifically, as Figure 2 、 Figures 4-6 shown, a plurality of groups of vertically arranged first stop bars 113 are arrayed on the side of the frame 11 away from the opening 111 to limit the outer wall of the cartridge 1, and each group of first stop bars 113 is used to limit one end of the lead frame in the cartridge 1. A plurality of groups of vertically arranged second stop bars 121 are arrayed on the side plate 12, and each group of second stop bars 121 corresponds to a group of first stop bars 113. Each group of second stop bars 121 is used to limit the other end of the lead frame in the cartridge 1, so that the lead frame in the cartridge 1 is more exposed, facilitating the better falling out of pollutants.

[0035] Furthermore, to avoid rigid contact between the two ends of the lead frame and the first stop bar 113 and the second stop bar 121 respectively, flexible pads 114 are covered on the opposite sides of the first stop bar 113 and the second stop bar 121. The flexible pads 114 can be made of cloth strips or rubber pads to prevent the two ends of the lead frame 1 from being caught in the flexible pads 114 and affecting the cleaning effect.

[0036] To facilitate the opening of the side plate 12, a pull ring 122 is provided on the side of the side plate 12 away from the hinge of the side plate 12 and the frame body 11.

[0037] The above are only the preferred embodiments of the present invention and do not represent the only or limit the present invention. Those skilled in the art should understand that various changes or equivalent substitutions made to the present invention without departing from the scope of the present invention all fall within the scope of protection of the present invention.
