[0059] The feeding device 1 of this embodiment realizes the cyclic feeding of multiple silos.

[0060] See also Fig. 9 A lifting and holding mechanism 15 is provided between the first rib cutting device 2 and the second rib cutting device 3. The second semiconductor device transfer mechanism 7 moves the semiconductor device on the lifting and holding mechanism 15 to the second rib cutting device 3. When the second semiconductor device transfer mechanism 7 picks up the semiconductor device, the second semiconductor device transfer mechanism 7 only moves horizontally but does not lift or lower. The lifting function is set on the lifting and holding mechanism 15. In this way, the second semiconductor device transfer mechanism 7 is fixed after transferring the semiconductor device to the second rib cutting device 3. The second rib cutting device 3 directly cuts the semiconductor device. The second semiconductor device transfer mechanism 7 can ensure that the position of the semiconductor device on the second rib cutting device 3 is accurate, and avoids the situation where the semiconductor device is displaced after the second semiconductor device transfer mechanism 7 moves.
[0061] See also Figure 10-11 The first semiconductor device transfer mechanism 6 includes a first transfer arm 601 and a dragging assembly 602, a positioning assembly 603 and a pushing assembly 604 arranged on the first transfer arm 601. The first transfer arm 601 is connected with a translation assembly.

[0062] The dragging assembly 602, the positioning assembly 603 and the pushing assembly 604 in this embodiment are two cylinders arranged side by side. During feeding, the first transfer arm 601 is located on the upper side of the semiconductor device tray 107, and the lifting assembly drives the positioning assembly 603 to fall. When the feeding mechanism 1 delivers the semiconductor device to the semiconductor device tray 107, the end of the semiconductor device contacts the positioning assembly 603 and stops, thereby positioning the semiconductor device. Then the lifting assembly drives the dragging assembly 602 to fall, and the pushing assembly 604 also falls under the drive of its lifting assembly. The lifting assembly drives the positioning assembly 603 to rise, and the first transfer arm 601 moves toward the first rib cutting device 2. During the movement, the pushing assembly 604 pushes the semiconductor device cut by the first rib cutting device 2 to the lifting and supporting mechanism 15. At the same time, the dragging assembly 602 drags the semiconductor device on the semiconductor device tray 107 to the first rib cutting device 2. The first transfer arm 601 returns to the upper side of the semiconductor device tray 107, and the first rib cutting device 2 performs rib cutting.
[0063] See also Fig.12 The first rib cutting device 2 includes a first rib cutting base 201, a first rib cutting lifting base 202, a first rib cutting male mold 203, a first rib cutting female mold 204 and a first rib cutting floating plate 205. The first rib cutting lifting base 202 is lifted and arranged on the upper side of the first rib cutting base 201, the first rib cutting male mold 203 is arranged on the first rib cutting lifting base 202, the first rib cutting female mold 204 is arranged on the first rib cutting base 201, the first rib cutting floating plate 205 is arranged on the lower side of the first rib cutting lifting base 202 through a first return spring 206, and the first rib cutting male mold 203 is arranged through the first rib cutting floating plate 205.
[0064] The first rib cutting lifting seat 202 drives the first rib cutting male mold 203 and the first rib cutting floating plate 205 to move downward, the first rib cutting male mold 203 is inserted into the first rib cutting nut and cuts the auxiliary rib 14, the first rib cutting floating plate 205 moves upward relative to the first rib cutting male mold 203 to compress the first return spring 206, when the first rib cutting lifting seat 202 drives the first rib cutting male mold 203 to move upward, the first rib cutting floating plate 205 is fixed relative to the first rib cutting nut under the action of the first return spring 206, so that the cut semiconductor device is firmly fixed on the first rib cutting nut, and the semiconductor device is placed to move upward with the first rib cutting male mold 203.
[0065] See also Fig.13 The auxiliary ribs 14 on the semiconductor device are cut off by using the first rib cutting male die 203 of the first rib cutting device 2 in cooperation with the first rib cutting female die.
[0066] See also Fig.14The lifting support mechanism 15 in this embodiment includes a support seat 1501 and a lifting component that drives the support seat 1501 to rise and fall. Hanging and yielding grooves 1502 are respectively opened on both sides of the upper surface of one end of the support seat 1501 close to the second tendon cutting device 3.
[0067] See also Figure 15-16 The second semiconductor device transfer mechanism 7 includes a second transfer arm 701, which is connected to a translation assembly that drives it to move horizontally. A punching and giving way groove 702 is provided in the middle of one end of the second transfer arm 701 close to the lifting and lowering support mechanism 15. A semiconductor device hanging column 703 corresponding to the hanging giving way groove 1502 is provided on the lower side of one end of the second transfer arm 701 close to the support seat 1501. After the support seat 1501 descends, one end of the second transfer arm 701 moves to the upper side of the support seat 1501, and then the support seat 1501 rises and makes the hole or groove of the semiconductor device hang with the semiconductor device hanging column 703, and then the second transfer arm 701 drags the semiconductor device back, so that the semiconductor device moves to the second rib cutting device 3.
[0068] The purpose of the punching clearance groove 702 is to avoid moving the second transfer arm 701 when the second rib cutting device 3 is punching. Since the second rib cutting device 3 is punching both sides of the semiconductor device, the punching clearance groove 702 only needs to be larger than the width of the part to be cut. After the second transfer arm 701 drags the semiconductor device on the supporting seat 1501 to the second rib cutting device 3, the second rib cutting device 3 directly performs punching. The function of the second transfer arm 701 is not only to transfer the semiconductor device, but more importantly to position the semiconductor device, thereby effectively improving the processing efficiency and processing accuracy.

[0070] Baffles 307 are provided on both sides of the second rib cutting master mold 304. The baffles 307 are spaced apart from the second rib cutting master mold 304 to form a blanking space. The baffles 307 prevent waste from splashing during the cutting process. The cut coils 9 fall into the waste box through the blanking space.
[0071] A plurality of negative pressure suction holes 308 are provided on the lower side of the second rib cutting male mold 303, and the second rib cutting lifting seat 302 drives the second rib cutting male mold 303 to move downward and contact the second rib cutting floating plate 305. During the downward movement of the second rib cutting male mold 303 and the second rib cutting floating plate 305, the semiconductor device contacts the second rib cutting female mold 304, so that the second rib cutting male mold 303 and the second rib cutting female mold 304 cooperate to cut off the semiconductor device part outside the second rib cutting floating plate 305, and after cutting, the negative pressure suction holes 308 absorb the semiconductor device on the second rib cutting floating plate 305, and after cutting, the second rib cutting male mold 303 moves upward together with the second rib cutting floating plate 305, and the second rib cutting male mold 303 always absorbs the semiconductor device through the negative pressure suction holes 308.
[0072] In this embodiment, the second cutting rib male mold 303 can also start adsorption after it falls and contacts the semiconductor device, so that the semiconductor device is stably fixed on the second cutting rib floating plate 305, preventing the semiconductor device from shifting during the cutting process. There is no need to rearrange the semiconductor device during subsequent testing, thereby improving test efficiency.

[0075] See also Fig. 20 The testing mechanism 4 includes a testing turntable 403 and a plurality of testing suction cups 401 and a testing probe seat 402 arranged on the turntable 403.

[0077] The translation assembly and lifting assembly described in this embodiment are selected from various structural forms such as air cylinder, electric cylinder, oil cylinder, lead screw or synchronous belt according to needs. The first semiconductor device transfer mechanism 6, the second semiconductor device transfer mechanism 7, and the third semiconductor device transfer mechanism 8 in this embodiment all have the function of positioning the semiconductor device, so they need to cooperate with the position detection switch, and the translation assembly of the first semiconductor device transfer mechanism 6, the second semiconductor device transfer mechanism 7, and the third semiconductor device transfer mechanism 8 is preferably a servo motor with a lead screw structure to accurately move the semiconductor device.
[0078] Working process: The push plate 1061 of the feeding device 1 pushes the semiconductor devices in the semiconductor device bin 101 horizontally onto the semiconductor device tray 107, the first transfer arm 601 drives the pushing assembly 604 to push the semiconductor devices cut by the first rib cutting device 2 onto the lifting and supporting mechanism 15, and at the same time the dragging assembly 602 drags the semiconductor devices on the semiconductor device tray 107 to the first rib cutting device 2, the first transfer arm 601 returns to the upper side of the semiconductor device tray 107, and the first rib cutting device 2 performs rib cutting.
[0079] The support seat 1501 is driven by the cylinder to descend, and one end of the second transfer arm 701 moves to the upper side of the support seat 1501, and then the support seat 1501 rises and makes the hole or groove of the semiconductor device and the semiconductor device hanging column 703 mutually hang, and then the second transfer arm 701 drags the semiconductor device back and moves the semiconductor device to the upper side of the second cutting rib floating plate 305. The second transfer arm 701 fixes and positions the semiconductor device, and then the second cutting device 3 performs rib cutting.
[0080] After cutting, the second rib cutting mold 303 absorbs the semiconductor device through the negative pressure suction hole 308 and rises, and the third drag seat 805 drives the drag seat suction cup 806 to move to the lower side of the second rib cutting mold 303. The lifting assembly drives the third drag seat 805 and the drag seat suction cup 806 to move upward and receive the semiconductor device absorbed by the second rib cutting mold 303. Then the third drag seat 805 drives the drag seat suction cup 806 to return to its original position, and the third upper transfer seat 801 drives the upper suction cup 803 of the semiconductor device to move to the upper side of the drag seat suction cup 806. The upper suction cup 803 of the semiconductor device descends and absorbs the semiconductor device on the drag seat suction cup 806, and then transfers the semiconductor device to the lower suction cup 804 of the semiconductor device. During the transfer process, the suction cup ensures that the position of the semiconductor device is fixed, and there is no need to rearrange the semiconductor devices in subsequent testing, thereby improving the test efficiency.
[0081] The turntable 403 drives the test suction cup 401 to absorb the semiconductor device on the semiconductor device lower suction cup 804 and transfer it to the test probe seat 402. The test probe seat 402 performs electrical tests on the semiconductor device, classifies the semiconductor device into qualified parts, unqualified parts and parts that need to be re-tested, and uses the turntable 403 and the test suction cup 401 to transport the semiconductor devices to corresponding stations. The qualified semiconductor devices are directly packaged or encapsulated by the packaging mechanism 5, and the other devices are transported to the corresponding stations for corresponding processing or re-testing.

Any person skilled in the art may use the above disclosed technical contents to change or modify them into equivalent embodiments with equivalent changes.
