Detailed Description
The present invention will be described in detail and with reference to the accompanying drawings, wherein:
fig. 1 is a schematic diagram of a module of an embodiment of an apparatus for inspecting lead frame according to the present invention, which includes a base 1, and a feeding module 10, a detecting module 20, and a discharging module 30 assembled on the base 1. In this embodiment, the lead frame automatic inspection apparatus further includes a terminal 40, and the terminal 40 is electrically connected to the feeding module 10, the detecting module 20, and the discharging module 30 respectively for control.
With respect to the feeding module 10, please refer to fig. 2 and fig. 3. The feeding module 10 may include a feeding platform 11, where the feeding platform 11 means a platform provided with a slide rail, and one or more working platforms with a slide groove may be disposed on the platform according to requirements, so that the slide groove of the working platform can slide freely on the platform corresponding to the slide rail. A pair of supporting frames 12 is vertically installed at the central portion of the feeding platform 11, and a guiding rail 13 is installed between each supporting frame 12 and the feeding platform 11, and an acute angle θ 1 is formed between each guiding rail 13 and a horizontal plane by using the feeding platform 11 as a reference of the horizontal plane.
When viewed from a single side, the guide rail 13 may be a pair of rails spaced apart by a predetermined distance, and respectively disposed at the left and right sides of the supporting frame 12, and a guide platform 14 having a fastening structure (such as a groove or a convex strip) correspondingly engaged with the rails may be fixed on the guide rail 13 by the fastening structure, such that the guide platform 14 can move up and down along the guide rail 13.
In order to make the feeding module 10 capable of being adjusted correspondingly according to the inclination angle of the stacked lead frame 2, an angle adjusting unit 17 may be further disposed on the worktable, the angle adjusting unit 17 is connected to the guiding rail 13, and includes an adjusting block 18 sliding on the feeding platform 11 and connected to the guiding rail 13, and the adjusting block 18 is slid to drive the guiding rail 13 and the horizontal plane to clamp the acute angle θ 1 for adjustment; in addition, a driving unit 19 can be disposed on the worktable, and the worktable can move up and down through the driving unit 19, so as to drive the guiding platform 14 to move up and down.
Referring to fig. 3, in view of the overall structure, a pair of guide rails 13 are symmetrically installed in opposite directions around the supporting frame 12, and the guide platform 14 is disposed on each guide rail 13 to support a lead frame group 15 to be tested, which is formed by stacking a plurality of lead frames 2. In this way, the lead frames 2 can be stacked one on top of the other on the guide platforms 14 by feeding from both sides simultaneously, and the guide platforms 14 are moved upward in an inclined direction to a feeding end 16 of the guide rail 13 according to the acute angle θ 1 and pushed by the driving unit 19.
The lead frame 2 reaching the feed end 16 can be moved by a first clip arm 21 so that the lead frame 2 can be clamped between the first clip arm 21. Referring to fig. 4, the first clamping arm 21 is disposed on an inspection rail platform beside the feeding module 10 and moves horizontally along a rail above the inspection rail platform. In this embodiment, in order to correspondingly receive the lead frame 2 from the feeding module 10 capable of feeding materials from both sides, the first clamping arm 21 and the detection rail platform are also configured to be in a pair of parallel postures.
The inspection module 20 further includes image capturing units 22 correspondingly disposed above the inspection rail platforms, and in one embodiment, a gantry 23 spanning the inspection rail platforms is erected on the base 1, and the image capturing units 22 are installed on the gantry 23. Thus, when the first clamping arm 21 moves close to the feeding module 10 and clamps the lead frame 2, the first clamping arm 21 will bring the lead frame 2 to move toward the door frame 23 on which the image capturing units 22 are mounted. The image capturing units 22 capture image information including at least one feature of the lead frame 2 (e.g., burr, corner-cut, etc.) as the lead frame 2 passes through the gantry 23. After the image acquisition unit 22 is electrically connected to the terminal 40, the image information can be transmitted to the terminal 40 and the terminal 40 is used for comparison and analysis to determine whether the lead frame 2 is a qualified product or an unqualified product.
In a non-limiting example, the image capturing unit 22 can be an image sensing device, but the invention is not limited thereto.
Referring to fig. 5, a second clamping arm 37 moves close to the first clamping arm 21 and moves toward the discharging module 30 after clamping the lead frame 2 passing through the detecting module 20. When moving above the discharging module 30, the two arms of the second clamping arms 37 will open, so that the leadframe 2 originally clamped between the second clamping arms 37 falls down onto the discharging module 30.
Fig. 6, 7 and 8 are a schematic view, a top view and a side view of the discharging module 30 of the present embodiment, respectively. The discharging module 30 includes a pair of discharging rail platforms 31 disposed in parallel, each of the discharging rail platforms 31 has a rail thereon, such that the lead frame 2 entering the discharging module 30 can be fixed on the rail directly or through other elements, and can move back and forth on the discharging rail platforms 31.
One side of each discharging rail platform 31 is provided with a qualified product channel 32 and a unqualified product channel 33 which are adjacently arranged, and the qualified product channel 32 and the unqualified product channel 33 respectively form acute angles theta 2 and theta 3 with the discharging rail platform 31 connected with the qualified product channel 32 and the unqualified product channel 33. In the present embodiment, the acute angles θ 2 and θ 3 may be the same angle, but in other embodiments, the acute angles θ 2 and θ 3 may be different angles according to requirements.
The discharging rail platform 31 in this embodiment further comprises a discharging shaft 34. The discharge shaft 34 has 3 positions, the discharge shaft 34 of FIG. 8 being in a lower position; the outfeed shaft 34 of FIG. 9 is in a waiting position; the discharging shaft 34 shown in fig. 10 is located at a receiving position, and the discharging shaft 34 is sequentially located at the waiting position, the receiving position, and the discharging position during the inspection process.
Wherein the discharging shaft 34 is in a standby state when the lead frame 2 has not entered the discharging module 30, and its position is maintained in a standby position almost horizontal to the discharging rail platform 31 as shown in the left side of fig. 9; when the second clamping arms 37 clamp the lead frame 2 and move to the upper side corresponding to the discharging shaft 34, the discharging shaft 34 will move upward to a receiving position as shown in the right side of fig. 9, so that after the two arms of the second clamping arms 37 are opened, the lead frame 2 will fall onto the discharging shaft 34 and move horizontally along the discharging rail platform 31 according to the result of the determination of the terminal 40 for the image information (i.e., the lead frame 2 is a good product or a bad product), as shown in fig. 10. The above design can not only shorten the operation time of the discharging shaft 34, but also avoid the occurrence of a crash condition caused by overlapping positions during the process of mutually matching and conveying the lead frame 2 by the discharging shaft 34 and the second clamping arm 37, so that the connection of the lead frame 2 is more accurate and smooth.
It should be noted that, in addition to the movement of the discharging shaft 34 being controlled by the terminal 40 based on the result of the determination of the image information (i.e., whether the lead frame 2 is a good or a bad product), the movement position of the second clamp arm 37 is also determined by the result of the determination of the terminal 40. For example, if the lead frame 2 is determined to be a defective product by the terminal 40 through the detection module 20, the terminal 40 controls the second clamp arm 37 and the discharging shaft 34 such that the discharging shaft 34 with the lead frame 2 placed thereon moves horizontally on the discharging rail platform 31 to the inlet of the defective product channel 33, and drops the defective lead frame 2 downward into the defective product channel 33 after the discharging shaft 34 descends to the blanking position (see fig. 8); on the contrary, if the lead frame 2 entering the discharging shaft 34 is determined as a qualified product by the terminal 40 when passing through the detecting module 20, the terminal 40 controls the second clamping arm 37 and the discharging shaft 34, so that the discharging shaft 34 with the lead frame 2 placed thereon moves horizontally on the discharging rail platform 31 to the inlet of the qualified product channel 32, and when the discharging shaft is lowered to a blanking position (see fig. 8), the qualified lead frame 2 falls downward and enters the qualified product channel 32.
The lead frames 2 dropped into the non-defective product passage 32 and the defective product passage 33 respectively slide on the non-defective product passage 32 and the defective product passage 33 at the inclination angles θ 2 and/or θ 3, and are respectively gathered and arranged in a non-defective product gathering region 35 and a defective product gathering region 36 extending from the non-defective product passage 32 and the defective product passage 33.
Referring to fig. 11 and 12, in another embodiment of the present invention, the non-defective product channel 32 and the defective product channel 33 are further provided with a side monolith member 38, the side monolith members 38 are symmetrically disposed at two sides of the non-defective product channel 32 and the defective product channel 33, and the distance between the side monolith members 38 can be adjusted to conform to the size of the lead frame 2 to be tested, so that the lead frames 2 can be arranged orderly during the testing process.
In order to speed up the inspection efficiency, the feeding module 10, the inspecting module 20, and the discharging module 30 may be disposed on the base 1 in pairs, so that the lead frames 2 can be simultaneously fed from two sides and inspected by two production lines. Not only can the defective products of the lead frame 2 be inspected in batches, but also the adjustable feeding module 10 can be adjusted to adapt to different inclination degrees of the stacked lead frames 2 during the feeding process. In addition, after entering the discharging module 30, the qualified products and the unqualified products are classified according to the quality control sorting result of the detecting module 20 and enter the qualified product collecting area 35 and the unqualified product collecting area 36, so that the production fluency of the factory can be improved, and the production efficiency can be further improved. However, the components included in the feeding module 10, the detecting module 20, and the discharging module 30 may be installed on the base 1 in an unpaired manner. For example, the feeder module 10 may comprise only a single support frame 12 and/or be provided with the guide rail 13 and the guide platform 14 on only a single side; the inspection module 20 may include only one inspection rail platform; alternatively, the discharging module 30 may include only one discharging rail platform 31 instead of the pair of discharging rail platforms 31 of the above embodiments, and the scope of the present invention is also covered.
Since the operation of the elements is substantially the same as that described in the embodiment when the elements are not installed in pairs, further description is omitted here.
In addition, the acute angles θ 1, θ 2 and θ 3 described in the present invention, that is, the "angle greater than 0 ° and less than 90 ° as defined in the mathematics, such as between 1 ° and 89 °, are not necessarily integers, but other angles such as 0.5 ° and 65.32 ° are also included in the scope of the" acute angle "described in the present invention.
The present invention has been described in detail, but the above description is only a preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention shall be covered by the present invention.
