[0028] In order to enable those skilled in the art to better understand the technical solutions of the embodiments of the present disclosure, the embodiments of the present disclosure are further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0029] like Figures 1 to 3 As shown, an embodiment of the present disclosure provides an ultra-high-density frame defective product removal jig 100 , including a base 110 , a rail 120 , a guide post 130 , a removal assembly 140 and a pressing mechanism 150 .

[0030] The rail 120 and the guide pillars 130 are both provided on the base 110. The rail 120 is used to carry the lead frame to be cut. The rail 120 is provided with a plurality of first positioning members 160. In this embodiment, two guide pillars 130 are provided at each end along the length direction of the base 110.

[0031] The first positioning member 160 is used to position and fix the entire ultra-high density frame placed on the track 120. In this embodiment, the first positioning member 160 can be, but is not limited to, a positioning pin.

[0032] Specifically, during the operation, the defective parts that need to be removed are first identified by observing the location of the marker on the frame to be removed. The entire strip frame is then placed on track 120, and the positioning holes of the frame corresponding to the parts to be removed are inserted into the corresponding positioning pins on track 120 to secure the frame. Furthermore, defective parts are removed from the strip frame. The marker marks on the strip are more visible and easier to identify than those on the granular form, thus reducing the labor costs associated with manual rejection of defective parts.

[0033] In this embodiment, the ultra-high-density frame to be removed can be accurately positioned and fixed in the working area by the rail and the first positioning member, so as to ensure the accuracy and consistency of the subsequent defective product removal operation.

[0034] like Figure 1 As shown, the cutting assembly 140 includes a knife holder 141, a plurality of cutters 142, and a plurality of second positioning members 143. The knife holder 141 is retractably mounted on the guide post 130. The first ends of the plurality of cutters 142 slide through and extend out of the knife holder 141. The second ends of the plurality of cutters 142 are connected to their corresponding second positioning members 143. When the second positioning members 143 are in the cutting position, the corresponding cutters 142 move downward.

[0035] In this embodiment, the second positioning member 143 can be, but is not limited to, a positioning pin. The second positioning member 143 has an initial position and a cutting position. Only when the second positioning member 143 is in the cutting position can the cutter connected thereto move downward to cut off a single product.

[0036] It should be noted that, in this embodiment, the plurality of second positioning members 143 and the plurality of cutters 142 are distributed in a matrix, which can correspond to a plurality of products of the entire ultra-high density frame.

[0037] The pressing mechanism 150 is fixed to the base 110 and is arranged on the top of the cutting assembly 140. When the target second positioning member is located at the cutting position, the pressing mechanism 150 is used to press down the cutting assembly 140 so that the corresponding target cutter moves down to the position of the defective frame product to be cut, and then cuts off the corresponding defective product.

[0038] Specifically, when performing the cutting operation, for a single defective product that needs to be cut, the target positioning pin corresponding to the single defective product is moved above the single defective product, and the target cutter corresponding to the target positioning pin moves downward. For products that do not need to be cut, there is no need to move the positioning pin, and the corresponding cutter remains in its original state, thereby locating any defective product that needs to be cut in each punch, and the pressing mechanism 150 is pulled to press the entire cutting assembly 140, and the target cutter moves down to the target defective product to complete the cutting of the single defective product, while ensuring that the rest of the frame is not affected.

[0039] In this embodiment, through the cooperation of the pressing mechanism and the cutting component, accurate cutting of defective products in ultra-high density frames can be achieved, and the defective parts in the frame can be removed. Only a single defective product is cut out each time, and other normal products are not affected, thereby improving the quality and performance of the overall product.

[0040] The ultra-high-density frame defective product removal jig of the disclosed embodiment can ensure that each defective product removal operation can be performed at the position of a required single product through the first positioning member and the second positioning member, and can accurately remove defective products in the ultra-high-density frame, ensuring the accuracy and consistency of the removal; it can achieve the removal of defective parts in the frame through precise removal, and only removes a single defective product each time without affecting other normal products, thereby improving the quality and performance of the overall product; the jig is simple to operate, can reduce the labor intensity of the operator, and improve work efficiency; the jig has high repeatability, can maintain the same removal effect in different batches of products, and ensure the stability of product quality; the jig can adapt to scenarios where there are defects in various positions of a single frame, and has strong versatility and flexibility.

[0041] For example, Figure 1 As shown, the cutting assembly 140 further includes a fixing plate 144 disposed on the top of the knife seat 141. The fixing plate 144 is provided with a plurality of adjustment slots, and a plurality of second positioning members 143 are inserted into the corresponding adjustment slots, and the second positioning members can be adjusted to the cutting position in the adjustment slots.

[0042] Specifically, the second positioning member 143 has two positions within the adjustment slot: an initial position and a cutting position. When the second positioning member 143 is moved to the cutting position, the cutter 142 connected thereto moves downward to cut off the corresponding single defective product. After the single defective product is removed, the second positioning member 143 is moved back to the initial position, and the corresponding cutter 142 moves upward to the initial position.

[0043] For example, Figure 1 As shown, the cutting assembly 140 further includes a first elastic member 145 and a floating plate 146. The first end of the first elastic member 145 is connected to the floating plate 146, and the second end of the first elastic member 145 is connected to the knife holder 141. The first ends of the plurality of cutters 142 slide through and extend out of the floating plate 146.

[0044] The floating plate 146 serves to fix and limit the first ends of the plurality of cutters 142, and the first elastic member 145 enables the cutting assembly 140 to return to its original position after completing a cutting action. In this embodiment, the first elastic member 145 can be, but is not limited to, a spring.

[0045] For example, Figure 1As shown, the ultra-high-density frame defective product removal jig 100 further includes a support column 170. The first end of the support column 170 is fixed to the base 110, and the second end of the support column 170 is used to support the floating plate 146 when the removal assembly 140 moves downward. Specifically, during the removal process, the removal assembly 140 moves downward, and the second end of the support column 170 abuts against the floating plate 146, providing support for the floating plate 146, and thus supporting the entire removal assembly 140.

[0046] For example, Figure 1 As shown, the ultra-high-density frame defective product removal jig 100 further includes a second elastic member 181, which is sleeved on the guide post 130 and elastically connected to the knife holder 141. The second elastic member 181 enables the knife holder 141 to move downward during the removal process and to move upward after the removal operation is completed.

[0047] For example, Figures 1 to 3 As shown, the ultra-high-density frame defective product removal jig 100 also includes a waste collection box 182, which is retractably inserted into the base 110. The base 110 is connected to the removal area of ​​the track 120. The waste collection box 182 is used to collect the removed defective products. The waste collection box 182 can be drawer-style and can also be provided with a handle to facilitate the withdrawal of the waste collection box 182.

[0048] In this embodiment, by providing a waste collection box, the defective products that are cut off can automatically fall into the waste collection box of the jig, which makes it easy to confirm the number of defective products and keeps the working environment clean and safe.

[0049] For example, Figures 1 to 3 As shown, the ultra-high density frame defective product removal jig 100 further includes a support plate 183 disposed on the base 110 . The two support plates 183 are disposed at both ends of the base 110 along the length direction of the base 110 and are located outside the guide pillars 130 .

[0050] like Figure 2 and Figure 3 As shown, the pressing mechanism 150 includes a pressing rod 151, a pressing block 152, and a trigger handle 153. The two ends of the pressing rod 151 are rotatably mounted on the support plate 183. The pressing block 152 is sleeved on the pressing rod 151. The trigger handle 153 is disposed at the end of the pressing rod 151. A non-slip cover is also provided on the trigger handle 153 to facilitate pressing the trigger handle 153.

[0051] Specifically, in this embodiment, when performing a defective product cutting operation, the handle 153 is pressed to 180°, and the corresponding pressing block 152 is flipped 180° and pressed to the top of the second positioning member 143 of the cutting assembly 140, so that the entire cutting assembly 140 moves downward, completing a cutting operation.

[0052] The ultra-high-density frame defective product removal jig of the disclosed embodiment achieves effective defective product removal processing of ultra-high-density frames through precise positioning and fixation of a single ultra-high-density frame product, accurate defective product removal operation, effective waste disposal, high-precision repeatability and comprehensive safety measures. It has a novel design, is easy to use, simple to operate, highly repeatable and has wide adaptability.
