[0031] Reference Figures 1 to 8 This application provides a lead frame testing device, comprising: a production mechanism for producing lead frames, the production mechanism being provided with a conveying section 110, the conveying section 110 being provided with a feeding component 120, the feeding component 120 being used for feeding or conveying lead frames; a testing mechanism 200 connected to the feeding component 120, the testing mechanism 200 being used for testing the lead frames conveyed and output by the feeding component 120, the testing mechanism 200 being provided with an output component 210, the output component 210 being used for outputting lead frames; and a receiving mechanism including a first receiving section 310 and a second receiving section 320, the first receiving section 310 being connected to the feeding component 120 and being used for receiving the lead frames fed and output by the feeding component 120, the second receiving section 320 being connected to the output component 210 and being used for receiving the lead frames output by the output component 210.

[0032] The lead frame inspection device of this application embodiment enables the lead frame to be inspected at intervals, thereby reducing the workload of the inspection mechanism 200, avoiding the stacking of lead frames, and ensuring the continuity and stability of production.

[0033] Reference Figures 1 to 3The feeding assembly 120 includes a baffle 130 and a first support member 140. The baffle 130 is elliptical and disposed on the conveying section 110. The baffle 130 is used to connect or disconnect the feeding assembly 120 from the detection mechanism 200. The conveying section 110 is provided with a feeding port in front of the baffle 130. The first support member 140 is movably disposed on the feeding port. The first support member 140 can open the feeding port to feed the lead frame. The first receiving section 310 is disposed below the feeding port. When the material is being unloaded, the baffle 130 descends, disconnecting the unloading assembly 120 from the detection mechanism 200. At this time, the lead frame stops at the first support 140, and then the first support 140 opens the unloading port, allowing the lead frame to be output from the unloading port, thus realizing the unloading output of the lead frame. When the material is being conveyed, the baffle 130 rises, connecting the unloading assembly 120 to the detection mechanism 200. At this time, the lead frame is conveyed to the detection mechanism 200 through the first support 140, thus realizing the conveying output of the lead frame.

[0034] It is conceivable that the conveying unit 110 is equipped with a support, and the support is equipped with a first driving component, with the baffle 130 connected to the first driving component. The first driving component is configured as a cylinder. The first driving component drives the baffle 130 to move, thereby achieving the timing of the baffle 130. The structure is simple and the operation is stable.

[0035] Of course, the baffle 130 can also be horizontally slidably disposed on the conveying section 110, or the baffle 130 can be rotatably disposed on the conveying section 110. As long as the baffle 130 can be connected or disconnected from the detection mechanism 200 of the feeding component 120, this application does not impose any restrictions on this.

[0036] As is easily understood, the first support member 140 is slidably disposed on both sides of the discharge port, and the first support member 140 is connected to a second driving member, which is disposed in the conveying section 110. The second driving member is configured as a cylinder. The second driving member drives the first support member 140 to move, causing the first support members 140 to move away from each other to open the discharge port, at which point the lead frame can be output from the discharge port, realizing the output of the lead frame; when the second driving member drives the first support members 140 to move closer together, the first support member 140 can support the lead frame.

[0037] It should be noted that the first support 140 can also be rotatably mounted at the feeding port. The first support 140 can be rotated to open the feeding port, thereby realizing the feeding output of the lead frame.

[0038] Reference Figure 1 , Figure 4 and Figure 5In this embodiment, the movement direction of the first receiving section 310 is perpendicular to the movement direction of the conveying section 110, which facilitates the receiving of the lead frame, resulting in a simple structure and easy operation. Further, the second receiving section 320 includes a first conveyor belt 330 and a second conveyor belt 340. The first conveyor belt 330 is disposed below the discharging component 210, and its movement direction is consistent with that of the first receiving section 310. The movement direction of the second conveyor belt 340 is perpendicular to that of the first conveyor belt 330 and faces towards the first receiving section 310. The second conveyor belt 340 and the first conveyor belt 330 are connected by a steering component 350, which is used to turn the lead frame from the first conveyor belt 330 to the second conveyor belt 340. By setting the steering component 350, the end of the second receiving section 320 is brought close to the first receiving section 310. At this time, only one worker is needed to simultaneously unload the first receiving section 310 and the second receiving section 320, saving labor, reducing costs, and making the structure reasonable and compact, reducing the space occupied.

[0039] Furthermore, the receiving mechanism also includes a workbench 360, which is located between the first receiving section 310 and the second conveyor belt 340. By setting up the workbench 360, workers can directly unload the lead frames from the first receiving section 310 or the second receiving section 320 and package them on the workbench 360. The structure is simple and the operation is convenient.

[0040] Reference Figure 6 The discharge assembly 210 has a second support 220 slidably mounted at its end. The second support 220 supports and outputs the lead frame. The discharge assembly 210 conveys the lead frame until it reaches the second support 220. At this point, the second support 220 slides, allowing the lead frame to be output from the discharge assembly 210 and fed onto the first conveyor belt 330 for transport. This facilitates the collection of the lead frame, resulting in a simple structure and easy operation.

[0041] Reference Figure 7 As can be conceived, the steering assembly 350 includes a base plate 351, a turntable 352, and a belt 353. The base plate 351 is equipped with a rotating unit 354, and the rotating unit 354 is equipped with a lifting unit 355. The turntable 352 is located within the lifting unit 355, and the belt 353 is located within the turntable 352. Specifically, the first conveyor belt 330 transports the lead frame, allowing it to enter the steering assembly 350 with the assistance of the belt 353. Subsequently, the lifting unit 355 drives the turntable 352 to rise above the first conveyor belt 330. At this time, the rotating unit 354 drives the turntable 352 to rotate, causing the belt 353 to move in the direction of the second conveyor belt 340. Finally, the lifting unit 355 drives the turntable 352 to descend, allowing the belt 353 to engage with the second conveyor belt 340, thereby transporting the lead frame to the second conveyor belt 340.

[0042] Reference Figure 1 , Figure 4 , Figure 5 and Figure 8 In some embodiments of this application, the receiving mechanism further includes a third receiving section 370, which is disposed at the front end of the discharging assembly 210. The third receiving section 370 is used to receive defective lead frames. The third receiving section 370 includes a third support member 371 and a guide belt 372. The discharging assembly 210 has a waste outlet, and the third support member 371 is movably disposed at the waste outlet. The third support member 371 can open the waste outlet to output defective lead frames. The guide belt 372 is disposed below the waste outlet. After the lead frame is inspected by the inspection mechanism 200, if the inspected lead frame is qualified, it enters the discharge assembly 210 through the third receiving section 370, and then is conveyed from the discharge assembly 210 to the second receiving section 320 for collection. If the inspected lead frame is unqualified, the third support member 371 opens the waste port, allowing the lead frame to be output from the waste port and conveyed by the guide belt 372, thereby realizing the automatic output of unqualified products without manual operation and improving work efficiency. It is easy to understand that the third receiving section 370 also includes a support member 373, which is ergonomically positioned below the waste port. Due to the significant height difference between the waste port and the guide belt 372, the support member 373 supports the lead frame and lowers it to the guide belt 372, thereby improving the stability and reliability of the operation.

[0043] In some embodiments of this application, a sensor is provided at the feed end of the detection mechanism 200. The sensor is used to detect whether there is material extrusion in the lead frame, and the sensor is connected to the unloading assembly 120. When the sensor detects material extrusion at the feed end of the detection mechanism 200, the baffle 130 in the unloading assembly 120 remains in a lowered state to prevent the lead frame from entering the detection mechanism 200. At this time, the unloading assembly 120 can only unload the lead frame until the material extrusion situation in the detection mechanism 200 is resolved, at which point the unloading assembly 120 can resume unloading the lead frame, thereby ensuring the continuity and stability of the operation.

[0044] The working process of the lead frame detection device described in this application embodiment is as follows: the production mechanism produces the lead frame, the conveying unit 110 conveys the lead frame, and then the unloading assembly 120 unloads or transmits the lead frame: when the unloading assembly 120 unloads, the baffle 130 descends to disconnect the connection between the unloading assembly 120 and the detection mechanism 200, so that the lead frame stops on the first support 140, and then the first support 140 opens the unloading port, so that the lead frame is output from the unloading port and collected by the first receiving part 310; when the unloading assembly 120 transmits, the baffle 130 rises to connect the connection between the unloading assembly 120 and the detection mechanism 200, at which time the lead frame is transmitted to the detection mechanism 200 for detection by the unloading assembly 120. The qualified lead frame is output by the discharge assembly 210 and finally collected by the second receiving part 320, while the unqualified lead frame is output by the third receiving part 370 at the front end of the discharge assembly 210. The lead frame testing device described in this application embodiment enables the lead frame to be tested at intervals, thereby reducing the workload of the testing mechanism 200, avoiding the stacking of lead frames, and ensuring the continuity and stability of production.

[0045] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
