Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of angle folding fixtures, in particular to a novel 90-degree angle folding fixture for a direct-insertion LED plug-in. Background Art
[0002] The "Z-shaped pins" of LEDs need to be bent during processing, and a bending jig is used in this process. Products made with existing bending jigs have pins that undergo two 90° bends. Due to the stress generated by the metal's inherent strength and the lack of a colloid and pin limiter design, the formed pins have varying degrees of left and right eccentricity. This means that the pins exposed outside the colloid are not aligned with the pins encapsulated within the colloid, and their horizontal planes are not aligned. As a result, some products that exceed the limit specifications may face quality risks such as solderability or poor soldering during customer processing. Utility Model Content
[0003] In response to the shortcomings of the existing technology, the utility model provides a new 90° corner bend fixture for direct-insertion LED plug-ins, which solves the problems of the existing LED corner bend fixture that is difficult to form two bends at one time, and easily causes the folded feet of the pins after forming to have insufficient angles, offset folded feet, and different heights between the pins and the colloid.
[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a new type of 90° angle fixture for direct-insertion LED plug-in, comprising a male mold and a female mold that can be molded together, wherein two upper limit grooves are provided on the adjacent sides of the male mold and the female mold, a lower limit groove is provided on one side of the female mold, a trapezoidal groove connected to the lower limit groove is provided on one side of the female mold, and a protrusion adapted to the trapezoidal groove is provided on one side of the male mold.
[0005] Preferably, the top of the female mold is fixedly connected to a transverse block, the female mold and the transverse block are integrally formed, the top of the male mold is fixedly connected to a colloid limiting block, and a colloid limiting groove is provided on the adjacent side of the transverse block and the colloid limiting block.
[0006] Preferably, the transverse block and the colloid limiting block are both provided with slope surfaces on both sides of the colloid limiting groove.
[0007] Preferably, an arc is provided at the junction of the colloid limiting groove and the slope surface, and an anti-stuck groove is provided at the corner of the colloid limiting groove.
[0008] Preferably, two limiting holes are provided on the top of the colloid limiting block, bolts movably passing through the limiting holes are provided on the top of the colloid limiting block, and internal thread grooves matching the bolts are provided on the top of the male mold.
[0009] Preferably, both ends of the upper limiting groove are provided with funnel-shaped stress release grooves.
[0010] Preferably, a longitudinal groove is provided on one side of the male mold and the female mold, and an internal threaded hole penetrating the male mold and the female mold is provided in the longitudinal groove.
[0011] Compared with the existing technology, the present invention provides a new 90° angle fixture for direct-insertion LED plug-ins, which has the following beneficial effects:
[0012] 1. By setting the upper limit groove, lower limit groove and protrusion, the two bends of the LED pin can be formed at one time, and the pin is limited during the forming process. As long as the metal parts of the mold are not worn, the product can only be folded into the required "Z-shaped pin" size and shape after the mold processing of this solution, preventing the pin from having poor forming problems such as insufficient angle, offset of the folding foot, and different heights between the pin and the colloid after forming.
[0013] 2. Through the setting of limit grooves and sloped surfaces, the position of the LED product in the mold can be automatically corrected so that it can only slide into the colloid limit groove. This is conducive to knowing the placement position of the LED material through the colloid limit block when debugging the machine, thereby greatly reducing the time spent on debugging the machine and the delayed production capacity.
[0014] 3. The arc and anti-stuck groove are set to prevent the sharp part of the connection between the slope surface and the colloid limiting groove from squeezing the colloid and causing the colloid to be pinched, resulting in poor appearance. When the colloid is squeezed and deformed, the deformed colloid can extend into the anti-stuck groove. After the LED is taken out of the mold, the deformed colloid automatically returns to its original shape, reducing the possibility of deformation and damage of the LED colloid when it is squeezed.
[0015] 4. By setting the colloid limit block and bolt, the size of the colloid limit groove can be flexibly adjusted to meet the limit requirements of LEDs with colloids of different sizes.
[0016] 5. The stress relief groove is set to effectively avoid the traction force on the colloid caused by metal bending during mold closing, eliminate the influence of bending stress on the colloid, and prevent the bracket, lead and chip encapsulated in the epoxy resin colloid from irreversible physical damage, which may lead to functional failure of the product.

[0024] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0025] In order to make the two 90° bends of the LED pins into a Z-shaped shape at the same time, and to prevent the deviation of the bends during extrusion, refer to Figure 1-Figure 5 As an embodiment of the present utility model, a new type of 90° angle fixture for direct-insertion LED plug-in is proposed, including a male mold 1 and a female mold 2 that can be molded together. Two upper limiting grooves 3 are provided on the adjacent sides of the male mold 1 and the female mold 2, a lower limiting groove 4 is provided on one side of the female mold 2, a trapezoidal groove 5 connected to the lower limiting groove 4 is provided on one side of the female mold 2, and a protrusion 6 adapted to the trapezoidal groove 5 is provided on one side of the male mold 1. When in use, the LED colloid is placed on the female mold 2, and the pins at the bottom of the LED colloid extend into the lower limiting groove 4 of the female mold 2, then the male mold 1 is moved, gradually approaching the female mold 2, and the protrusion 6 on the male mold 1 enters the trapezoidal groove 5, and the LED pins are pushed into the lower limiting groove 4 along the trapezoidal groove 5. At the same time, the male mold 1 The protrusion on the top pushes the pin into the upper limit groove 3. Since the two ends of the "Z-shaped pin" are respectively limited by the upper limit groove 3 and the lower limit groove 4 when being squeezed, it cannot be laterally offset when being squeezed. Therefore, the two bends of the LED pin can be formed at one time, and the pin is limited during forming. As long as the metal parts of the mold are not worn, the product can only be folded into the required size and shape of the "Z-shaped pin" after being processed by the mold of this scheme, preventing the problems of poor folding foot forming such as insufficient angle of the folding foot, folding foot offset, and different heights between the pin and the colloid after forming. After the LED pin is formed, it is removed from between the male mold 1 and the female mold 2, and then the above process can be repeated when the LED pin needs to be folded into a "Z-shaped pin".
[0026] In order to facilitate the fixation of LED colloid, refer to Figure 1 and Figure 4 , the top of the female mold 2 is fixedly connected with a cross block 7, the female mold 2 and the cross block 7 are integrally formed, and the top of the male mold 1 is fixedly connected with a colloid limit block 8, and a colloid limit groove 9 is provided on the adjacent side of the cross block 7 and the colloid limit block 8. The cross block 7 and the colloid limit block 8 are both provided with a slope surface 10 on both sides of the colloid limit groove 9. When in use, the colloid of the LED is placed in the colloid limit groove 9. When the colloid placement position of the LED is offset, the male mold 1 will squeeze the colloid when it approaches the female mold 2, pushing the colloid to slide along the slope surface 10 and finally slide into the colloid limit groove 9. The colloid limit groove 9 limits the LED when it folds the corner, which can automatically correct the position of the LED product in the mold so that it can only slide into the colloid limit groove 9, which is beneficial for knowing the placement position of the LED material through the colloid limit block 8 when debugging the machine, thereby greatly reducing the time spent on debugging the machine and the delayed production capacity.
[0027] In order to prevent damage to the LED colloid when it is squeezed by the male mold 1 and the female mold 2, refer to Figure 5 , an arc 11 is provided at the junction of the colloid limiting groove 9 and the slope surface 10, and an anti-stuck groove 12 is opened at the corner of the colloid limiting groove 9. When in use, the male mold 1 gradually approaches the female mold 2. When the position of the LED colloid is offset, the male mold 1 will push the colloid to slide along the slope surface 10, and then slide into the colloid limiting groove 9. In this process, the junction of the slope surface 10 and the colloid limiting groove 9 will produce a certain amount of extrusion on the colloid. In this embodiment, an arc 11 is provided at the junction of the slope surface 10 and the colloid limiting groove 9, which can prevent the sharp part of the junction of the slope surface 10 and the colloid limiting groove 9 from squeezing the colloid and pinching the colloid, resulting in poor appearance. When the colloid is squeezed and deformed, the deformed colloid can extend into the anti-stuck groove 12. After the LED is taken out of the mold, the deformed colloid automatically returns to its original shape, reducing the possibility of deformation and damage of the LED colloid when it is squeezed.
[0028] In order to adapt the mold to the angle requirements of LEDs of different sizes, refer to Figure 1 and Figure 5 , two limiting holes are provided on the top of the colloid limiting block 8, and a bolt 13 that movably passes through the limiting holes is provided on the top of the public mold 1. An internal thread groove that is compatible with the bolt 13 is provided on the top of the public mold 1. When in use, the colloid limiting block 8 is slid along the public mold 1 until the colloid can be placed in the colloid limiting groove 9 between the colloid limiting block 8 and the cross block 7, and then the bolt 13 is rotated. After the bolt 13 enters the interior of the public mold 1, the colloid limiting block 8 is fixed to the public mold 1. At this time, the colloid of the LED can be placed in the colloid limiting groove 9 for limiting. The size of the colloid limiting groove 9 can be flexibly adjusted to meet the limiting requirements of LEDs with colloids of different sizes.
[0029] In order to prevent the LED pins from pulling the LED colloid when squeezing the LED pins, refer to Figure 2 and Figure 3 Both ends of the upper limit groove 3 are provided with funnel-shaped stress relief grooves 14. When in use, the stress relief grooves 14 are used to release the stress on the LED pins when bending, effectively avoiding the traction force generated by the metal bending on the colloid during mold closing, eliminating the influence of the bending stress on the colloid, and preventing the bracket, lead, and chip encapsulated in the epoxy resin colloid from irreversible physical damage, resulting in functional failure of the product.
[0030] A longitudinal groove is provided on one side of the male mold 1 and the female mold 2. An internal threaded hole is provided in the longitudinal groove and passes through the male mold 1 and the female mold 2. The internal threaded hole facilitates the use of a screw to drive the male mold 1 closer to and away from the female mold 2, thereby realizing the automated process of folding the corners.
[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
