The screening unit is located downstream of the detecting unit and includes a screening seat capable of receiving the electronic component transported from the detecting unit, the screening seat being driven to automatically reciprocate between a reserved position and a eliminated position Moving, when the electronic component is qualified, the screening device drives the electronic component to move to the reserved position, and when the electronic component fails to be detected, the screening seat drives the electronic component to move to the eliminated position.

The utility model has the advantages that the heating unit heats the electronic component, simulates a state of high temperature when the electronic component is used, and then uses the detecting unit to perform detection, and the detecting method can truly reflect the condition and actual use requirement of the electronic component during use. . Moreover, the heating unit, the detecting unit and the screening unit form a continuous and automatic heating, detecting and screening operation, so that the working process is coherent, fast and convenient.

Referring to FIGS. 1 to 4, an embodiment of the electronic component detecting device of the present invention is used for detecting at least one electronic component 1. This embodiment is an example of detecting and transporting a plurality of electronic components 1, each of which includes a body. 11, and a plurality of pins 12 on the body 11. And a feeding channel 21 for transmitting the electronic component 1 is connected upstream of the detecting device. The detecting device of this embodiment includes a loading platform 3, and a heating unit 4, a transmission unit 5, a detecting unit 6, and a screening unit 7 mounted on the stage 3.

The stage 3 includes an upstream side 31 and a downstream side 32 that are spaced apart from each other, and a mounting surface 33 that faces upwardly and gradually slopes downward from the upstream side 31 toward the downstream side 32. The heating unit 4, the transport unit 5, the detection unit 6 and the screening unit 7 are located on the mounting surface 33.

The heating unit 4 is connected to the feed channel 21 and includes a heating module 41 for heating the electronic component 1. The heating module 41 is provided with a plurality of heating tubes (not shown) that can be energized and heated. The heating module 41 includes a heating surface 411 facing upward and for the electronic component 1 to be placed.

The transmission unit 5 is located on the side of the heating unit 4 and includes a track 51 extending longitudinally in a transport direction 81, and a reciprocating movement in an actuating direction 82 for transporting the heated electronic component 1 to The transport mechanism 52 of the track 51. The transport direction 81 of the present embodiment is a direction to the rear, which is perpendicular to the transport direction 81 and is a left-right direction.

The rail 51 extends obliquely downward from the upstream side 31 toward the downstream side 32 along the mounting surface 33 of the stage 3, and extends from the side of the heating unit 4 through the detecting unit 6 and the screening unit 7 This design allows the electronic component 1 to automatically move downstream along the track 51 by its own weight.

The transport mechanism 52 includes a transport base 521 located above the heating module 41, and a first power module 522 for driving the transport base 521 to move. The carriage 521 includes an outer frame 523 having a substantially square shape, and a plurality of grids 524 extending downward from the outer frame 523 and being in the form of an upright sheet. The grids 524 are spaced apart from one another and extend in the direction of transport 81. Any two adjacent grids 524 define a channel 525 extending in the direction of transport 81 and capable of receiving the electronic component 1. In the guiding grooves 525, the leftmost guiding groove 525 is adjacent to the track 51, and the rightmost guiding groove 525 is adjacent to the feeding channel 21.

The transport base 521 can be driven by the first power module 522 to move between an initial position (the first flow of FIGS. 1 and 4) and a transfer position (the second flow of FIG. 4). When the transport base 521 is in the initial position, the position of the rightmost guide groove 525 corresponds to the feed passage 21, and can receive the electronic component 1 from the feed passage 21. In the transfer position, the position of the leftmost guide groove 525 corresponds to the track 51, and the electronic component 1 in the leftmost guide groove 525 can be fed into the track 51.

The first power module 522 is configured to drive the transport base 521 to move left and right in the actuating direction 82, and can also drive the transport base 521 to move up and down. The first power module 522 of the present embodiment includes a plurality of pneumatic cylinders 526, a plurality of slide rails for mounting the pneumatic cylinders 526, and a clamping mechanism for connecting the pneumatic cylinders 526 and the transport base 521. In the implementation of the present invention, the structure of the first power module 522 need not be limited, because in the mechanical device, there are many designs for controlling the up and down movement of the element and the left and right movement, and this is not a modification of the present invention.

The detection unit 6 is located on the side of the transmission unit 5 and is located downstream of the heating unit 4. The detecting unit 6 can receive the electronic component 1 delivered from the track 51 and perform related electrical detection on the electronic component 1.

Referring to Figures 1, 5 and 6, the screening unit 7 is located downstream of the detecting unit 6, and includes a mast 71 extending left and right in the actuating direction 82, a movably mounted on the mast 71 and capable of being mounted thereon. The screening seat 72 of the electronic component 1 delivered from the detecting unit 6 and a second power module 73 for driving the screening seat 72 are moved. The screening seat 72 includes a pocket 721 extending therethrough in the direction of transport 81. The screen holder 72 can be driven to automatically reciprocate in the actuating direction 82, thereby switching between a reserved position (as in the imaginary line of Figure 6) and a eliminated position (as shown in the solid lines of Figures 1 and 6). In the eliminated position, the position of the screening seat 72 corresponds to the track 51. In the retained position, the screening seat 72 is remote from the track 51 and moves to a position corresponding to one of the discharge channels 22. When the electronic component 1 passes the detection, the screening seat 72 drives the electronic component 1 to move to the reserved position. When the electronic component 1 fails to be detected, the screening seat 72 drives the electronic component 1 to move to the eliminated position. The second power module 73 controls the movement of the screening seat 72 by means of a pneumatic cylinder driving operation.

Referring to FIG. 1 , 3 , 4 , and 6 , when the present invention is used, the electronic component 1 can be continuously input into the feeding channel 21 , and the electronic components 1 can be arranged to be arranged in a plurality of rows of electronic component groups 10 through the carrier 521 (to drive The arrangement will be followed by instructions). Each row of electronic component groups 10 of the present embodiment includes a plurality of the electronic components 1 arranged along the transport direction 81. The rows of electronic component groups 10 are arranged at right and left intervals along the actuating direction 82, and each row of electronic components The set 10 can correspond to one of the guide grooves 525 of the transport base 521. When the novel detection is used, the electronic component 1 is first heated by the heating unit 4 to raise the temperature of the electronic component 1 to simulate the temperature at which the electronic component 1 is used.

When the transport base 521 is moved toward the track 51 from the initial position (the first flow of FIG. 4) and moved to the transfer position (the second flow of FIG. 4), the transport base 521 can pass through each of its grids 524. The electronic component group 10 pushes a distance to the left. At this time, the guide groove 525 located at the leftmost side moves above the track 51, and the electronic component 1 in the leftmost guide groove 525 can be pushed into the track 51 by the carriage 521 and transmitted along the track 51 to The detection unit 6. Then, the transport base 521 is controlled by the first power module 522 to be lifted up to a first position (the third flow of FIG. 4), and moves along the operating direction 82 back to a second position above the initial position. The position (the fourth flow of FIG. 4) is further lowered back to the initial position by the second position (the fifth flow of FIG. 4), and the grids 524 of the transport base 521 are again located in the electronic component group 10 Thereafter, the carriage 521 can be driven again to repeat the same movement to successively drive each row of electronic component groups 10 into the track 51. Of course, in the implementation of the present invention, the transport base 521 can also drive only one electronic component 1 into the track 51 at a time, and it is not necessary to drive several ones at a time.

Then, the electronic components 1 enter the detecting unit 6 for electrical detection, and after the electronic components 1 are detected, they continue to move along the track 51 toward the screening unit 7. When the screening seat 72 is located at the elimination position (as shown in FIG. 1 and FIG. 6), the position of the pocket 721 corresponds to the rail 51 and can receive the electronic component 1 delivered from the rail 51. The qualified electronic component 1 will continue to move downstream along the track 51 through the pocket 721. If the electronic component 1 passes the test, the screening seat 72 will move to the right in the actuating direction 82 to the reserved position (as shown in the imaginary line position in FIG. 6), and the qualified electronic component 1 enters the discharge channel 22 for subsequent The process is either collected.

It is added to explain how the electronic components 1 are arranged in a plurality of rows on the heating unit 4. Initially, the transporting seat 521 is located at the initial position, and the plurality of electronic components 1 enter the guiding groove 525 of the transporting seat 521 located at the rightmost side via the feeding channel 21, and the electronic components 1 are arranged in the heating unit 4 The heating surface 411 is automatically aligned in a row along the guide groove 525. Then, the transport base 521 is moved to the left by one space to the transfer position to push the electronic component group 10 located in the first row on the right side to the left to become the second row on the right side, and the position of the first row on the right side becomes empty. The transport base 521 is further raised, moved right, and lowered from the transport position to return to the initial position. Then, the feeding channel 21 retransmits the plurality of electronic components 1 into the rightmost guiding groove 525. The electronic components 1 become the electronic component group 10 of the first row on the right side, and then the transporting block 521 moves to the left again to The two rows of electronic component groups 10 on the right side push one cell to the left to become the electronic component group 10 of the second row and the third row on the right side. According to this process, the heating unit 4 is finally covered with a plurality of rows of the electronic component groups 10.

In summary, the heating element 4 heats the electronic components 1 to simulate a state of higher temperature when the electronic component 1 is used, and then uses the detecting unit 6 to perform detection. This detection method can truly reflect the use of the electronic component 1. The situation and actual use requirements. Moreover, the heating unit 4, the detecting unit 6 and the screening unit 7 are matched with each other to form a continuous and automatic heating, detecting and screening operation, so that the working process is continuous, fast and convenient.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
