Description

Technical Field

[0001] The present application relates to the technical field of electronic component processing, and in particular to a device for forming and processing electronic component connection terminals. Background Art

[0002] Electronic component terminals are a common electrical connector used to fix and connect wires or other conductors. Terminals are usually made of metal materials with good conductivity and certain strength, such as copper alloys, brass, etc. With the advancement and development of science and technology, terminal forming processing is moving towards a funnier, more precise and more intelligent direction, which not only improves production efficiency, but also ensures the consistency and reliability of product quality.

[0003] The Chinese patent with publication number CN114515790A and name "A device for forming and processing terminal blocks for electronic components" has an adjusting mechanism on the bottom plate for simultaneously feeding and discharging the copper plates of the terminal blocks, and two clamping mechanisms for fixing the copper plates of the terminal blocks are provided on the adjusting mechanism. Each die is provided with an ejection mechanism inside which can automatically lift up the waste after punching and cutting. The adjusting mechanism includes two pairs of baffles arranged on the left and right sides of the top of the bottom plate, one pair of baffles is rotatably connected with a threaded rod, and the other pair of baffles is fixedly connected with a limit rod parallel to the threaded rod, and the clamping mechanism is arranged on the threaded rod and the limit rod. Under the action of the adjusting mechanism, the two clamping mechanisms in the present invention can respectively clamp and transport the unprocessed copper plates of the terminal blocks and the copper plates of the terminal blocks after punching, so that the two clamping mechanisms can automatically feed and discharge the mold, thereby improving the punching efficiency of the mold for the copper plates of the terminal blocks.

[0004] The prior art of the above patent can also realize forming of electronic component terminals, mainly by positioning and stamping. However, when stamping creases on the plate, since there are many bending positions required on the edge of the metal plate, when bending at the same time, the straightness of the creases at multiple groups of bending positions is difficult to be distributed in parallel, which often causes the creases to be tilted or deviated, thereby increasing the defective products. In addition, the prior art may make it difficult to unload the material after the stamping is completed, resulting in the stamping material following the stamping head to rise, causing safety accidents.

DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] See also Figure 1-Figure 11 The embodiment of the present invention provides an electronic component terminal forming processing device, comprising: a bracket 1, on the upper part of which a protective cover 11 is fixedly installed, and the protective cover 11 is a U-shaped structure; a conveying component 2, which is fixedly installed on the upper part of the bracket 1, and the conveying component 2 is used to intermittently convey the uncut metal sheet to the left; a cutting component 3, which is fixedly installed on the upper part of the bracket 1, and the cutting component 3 is used to cut the metal strip conveyed on the conveying component 2 (refer to Fig.10); a die assembly 4, which is fixedly mounted on both side walls of the protective cover 11, and is used to provide the unformed metal sheet with the shape and support required for forming; a punch assembly 5, which is fixedly mounted on the inner upper end of the protective cover 11, and is used to provide an extrusion force to the unformed metal sheet so that the desired shape is formed through the die assembly 4; a collecting assembly 6, which is fixed on the upper part of the die assembly 4, and is used to collect and store the formed metal sheets.

[0033] In the above technical solution, as the conveying component 2 conveys the metal sheet at a uniform speed, when the metal sheet reaches the position of the cutting component 3, the die components 4 on both sides move towards each other until they merge, and then the punch component 5 moves downward, and the punch component 5 pushes the die component 4 to drive the cutting component 3 to cut the metal sheet on the conveying component 2. After the cutting is completed, the punch component 5 is reset, the extrusion force on the upper end of the die component 4 disappears, the die component 4 rises and resets, and the die component 4 drives the cutting component 3 to move horizontally to both sides and reset, and then the punch component 5 moves downward , the cut sheet metal plate is adsorbed. After the adsorption is completed, the punch assembly 5 drives the metal plate to move upward until the metal plate is higher than the die assembly 4, and then the die assembly 4 merges inward, and the punch assembly 5 drives the metal plate to move downward until the metal plate enters the die assembly 4. In the process of the metal plate entering the die assembly 4, the punch assembly 5 simultaneously pushes the die assembly 4 to drive the cutting assembly 3 to cut the metal plate on the conveying assembly 2. The die assembly 4 can prevent the metal plate from crease deviation during the forming process.

[0034] See also Figure 2 As shown, as the preferred technical solution of this embodiment, the conveying assembly 2 includes a mounting plate 21, a support roller 22 and a conveying roller 23, and the bracket 1 is fixedly mounted with a symmetrical mounting plate 21, rotatable support rollers 22 are mounted between the mounting plates 21, and rotatable conveying rollers 23 are mounted above the support rollers 22, wherein the conveying roller 23 on the left side is electrically driven.

[0035] In the above technical solution, the metal sheet is passed through the gap between the support roller 22 and the conveying roller 23. As the conveying roller 23 on the left rotates, the conveying roller 23 drives the metal sheet to be intermittently conveyed on the bracket 1. After the cutting component 3 completes cutting, the conveying roller 23 continues to convey until the punch component 5 completes the adsorption of the cut metal sheet.

[0036] See Figure Figure 2 As shown, as a preferred technical solution of this embodiment, the cutting assembly 3 includes an upper mold 31 and a lower mold 32 , wherein the upper mold 31 is fixedly mounted on the lower side of the die assembly 4 , and the lower mold 32 is fixedly mounted on the upper side of the bracket 1 .

[0037] In the above technical solution, the conveying assembly 2 drives the metal sheet to be located below the upper die 31 and above the lower die 32, and the punch assembly 5 pushes the die assembly 4 to drive the upper die 31 to move downward, so that the upper die 31 cooperates with the lower die 32, thereby realizing cutting of the metal sheet.

[0038] Continue reading Figure 3 and Figure 4 As shown, as a preferred technical solution of this embodiment, the die assembly 4 includes an electric push rod 41, a sliding block 42, a die frame 43, a driving plate 44, a telescopic rod 1 45, a correction mechanism 46, a folding mechanism 47 and a disengagement mechanism 48. The electric push rod 41 is fixedly mounted on the inner wall of the protective cover 11, and the sliding block 42 is fixedly mounted on the extended end of the electric push rod 41. A slide groove is provided on the outer surface of the die frame 43, and the sliding block 42 is slidably arranged in the slide groove. A spring 1 is connected between the sliding block 42 and the slide groove. An extrusion cavity is provided on the die frame 43, and a long space is provided between the side walls of the extrusion cavity. A groove, a short groove, a driving plate 44 is arranged in the connecting groove for sliding up and down, a symmetrical circular groove is provided on the die frame 43, a telescopic rod 45 is fixedly installed in the circular groove, the protruding end of the telescopic rod 45 is fixedly connected to the lower end surface of the driving plate 44, a correction groove is provided on the driving plate 44, and the correction groove corresponds to the position of the long groove, a slidable correction mechanism 46 is arranged in the correction groove, a folding groove is provided on the die frame 43, the folding groove is connected to the long groove, a folding mechanism 47 is fixedly installed in the folding groove, a disengagement groove is provided on the die frame 43, the disengagement groove is connected to the short groove, a disengagement mechanism 48 is fixedly installed in the disengagement groove.

[0039] In the above technical scheme, when stamping the metal sheet, the electric push rod 41 pushes the sliding block 42 to drive the die frame 43 to merge inwardly. After the merging is completed, the punch assembly 5 drives the cut metal sheet in the adsorption to move downward. When the metal sheet is attached to and squeezed by the driving plate 44, the driving plate 44 squeezes the folding mechanism 47 during the downward movement of the driving plate 44. The folding mechanism 47 moves to perform preliminary shaping on both sides of the metal sheet. When the driving plate 44 is flush with the upper surface of the die frame 43, the folding mechanism 47 completes the folding of the edge of the metal sheet. As the punch assembly 5 continues to move downward, when the driving plate 44 reaches the position of the disengagement mechanism 48, the thickness of the driving plate 44 is limited by the disengagement mechanism 48, and the driving plate 44 shrinks, so that when the driving plate 44 moves downward, the disengagement mechanism 48 does not affect the driving plate 44. As the punch assembly 5 continues to move downward, when the driving plate 44 reaches the bottom of the extrusion cavity, the die frame 43 squeezes the correction mechanism 46, so that the correction mechanism 46 extends out of the driving plate 4 4. The correction mechanism 46 and the punch assembly 5 perform secondary shaping on the initially shaped sheet material, so that the metal sheet material is punched to the expected forming effect. (While the punch assembly 5 is punching the metal sheet material, the conveying assembly 2 drives the strip metal sheet material to be conveyed so that the uncut area is moved to the bottom of the upper mold 31. During the downward pressing process of the punch assembly 5, the die frame 43 is pressed down synchronously, ensuring that the current metal sheet material is stamped and formed while the strip metal sheet material below is cut. At this time, the cut metal sheet material is waiting for subsequent stamping.) When the punch assembly 5 completes the stamping of the metal sheet material, the punch assembly 5 withdraws, and the die frame 43 is reset. When the punch assembly 5 drives the formed metal sheet material to the position of the disengagement mechanism 48, the disengagement mechanism 48 limits the position of the metal sheet material, so that the metal sheet material stays on the driving plate 44. During the resetting process of the die frame 43, the collecting assembly 6 pushes up one side of the formed metal sheet material, so that the metal sheet material is collected and stored from the driving plate 44 through the collecting assembly 6.

[0040] Continue reading Figure 3 As shown, as a preferred technical solution of this embodiment, the correction mechanism 46 includes a correction mold 461 and a pushing frame 462. The correction mold 461 is set in the correction groove for sliding up and down. The lower end of the correction mold 461 is provided with a pushing frame 462, and a spring 2 is connected between the pushing frame 462 and the driving plate 44.

[0041] In the above technical scheme, the correction die 461 and the pushing frame 462 move downward with the driving plate 44. When the lower end of the pushing frame 462 is squeezed by the die frame 43, the driving plate 44 continues to move downward, and the pushing frame 462 drives the correction die 461 to stop moving, so that the correction die 461 extends out from the driving plate 44. The extended correction die 461 cooperates with the punch assembly 5 to perform secondary extrusion and shaping on the bending part of the initially shaped metal sheet. After shaping, the driving plate 44 moves upward. Under the action of spring 2, the pushing frame 462 drives the correction die 461 to reset and hide in the driving plate 44.

[0042] See also Figure 3 and Figure 4 As shown, as a preferred technical solution of this embodiment, the folding mechanism 47 includes a horizontal push block 471, a limiter 472, a vertical push block 473, a push plate 474 and an unlocking member 475. The horizontal push block 471 is slidably arranged in the folding groove, and the left and right sides of the horizontal push block 471 are provided with inclined surfaces. The horizontal push block 471 is elastically connected to the folding groove. A limiter groove is provided on the horizontal push block 471, and a limiter 472 is slidably arranged in the limiter groove. A spring 3 is connected between the limiter 472 and the limiter groove, and the vertical push block 473 is set in the folding groove for sliding up and down. The lower end face of the vertical push block 473 is provided with an inclined surface matching with the horizontal push block 471. The vertical push block 473 and the folding groove are connected elastically. The inner side face of the push plate 474 is installed on the inner side wall of the folding groove through a pin shaft. An unlocking member 475 for sliding left and right is set in the folding groove. The inner side face of the unlocking member 475 is provided with a symmetrical chamfered structure. The outer end inclined surface of the unlocking member 475 is a structure that gradually tilts upward from the inside to the outside, and the unlocking member 475 and the horizontal groove are elastically connected.

[0043] In the above technical solution, when the driving plate 44 moves downward, the driving plate 44 squeezes the horizontal push block 471, so that the horizontal push block 471 moves outward. During the movement of the horizontal push block 471, the outward-moving horizontal push block 471 squeezes the vertical push block 473, so that the vertical push block 473 moves upward. The vertical push block 473 flips the push plate 474 upward, and the flipped push plate 474 performs a preliminary bending on the metal sheet. At the same time, when the horizontal push block 471 moves outward, the limit member 472 follows the movement. When the limit member 472 moves to the position beyond the unlocking member 475, under the action of the spring three, the limit member 472 moves upward The horizontal push block 471 is hidden in the folding groove and the position between the two forms a temporary lock. At this time, the flipping angle of the push plate 474 reaches the maximum value, thereby completing the preliminary bending of the metal sheet. When the metal sheet is stamped, the driving plate 44 is reset, and the unlocking member 475 is squeezed. The outer inclined surface of the unlocking member 475 squeezes the upper end of the limiting member 472, causing the limiting member 472 to drop. At this time, the limiting member 472 no longer locks the position of the horizontal push block 471 and the folding groove. The unlocked horizontal push block 471 moves inward and resets under the action of elasticity. Under the action of the elastic connection, the various components of the folding mechanism 47 are reset.

[0044] See also Figure 5 , Figure 6 and Figure 7 As shown, the disengagement mechanism 48 includes a fixed rod 481, a connecting plate 482, an arc plate 483, a limit plate 484, an upper sawtooth 485 and a lower sawtooth 486. The fixed rod 481 is fixedly installed in the disengagement groove, and a connecting plate 482 is rotatably provided on the fixed rod 481. A torque spring is connected between the connecting plate 482 and the fixed rod 481. An arc plate 483 is fixedly installed on the connecting plate 482. The arc plate 483 has a semicircular structure, and inclined surfaces are provided at both ends of the arc plate 483. A through groove is opened on the driving plate 44, and a limit plate that can slide up and down is provided in the through groove. The positioning plate 484, the limiting plate 484 and the driving plate 44 cooperate to adjust the side height of the driving plate 44, so as to cope with the extrusion cooperation with the arc plate 483 under different conditions. An upper serration 485 is fixedly installed on the positioning plate 484, and a lower serration 486 is fixedly installed on the inner side wall of the through groove. The upper serration 485 and the lower serration 486 are plug-fitted together. The plug-fitting between the upper serration 485 and the lower serration 486 is to ensure that the lower end of the arc plate 483 will not enter the inside of the through groove, thereby ensuring that the lower end of the arc plate 483 is always squeezed by the side wall.

[0045] In the above technical scheme, the driving plate 44 is squeezed by the punch assembly 5 and thus descends. At this time, the driving plate 44 drives the limiting plate 484, the upper serration 485 and the lower serration 486 to move downward. When the limiting plate 484 contacts the lower protruding end of the arc plate 483, the limiting plate 484 is completely retracted into the through groove after being squeezed (when the lower protruding end of the arc plate 483 does not squeeze the lower end of the limiting plate 484, the limiting plate 484 is always in a state of extending out of the through groove under the action of gravity). At this time, the sum of the height of the driving plate 44 and the thickness of the metal sheet is less than the diameter of the arc plate 483. When the lower end of the driving plate 44 is squeezed by the lower protruding end of the arc plate 483, under the action of the squeezing force, the arc plate 483 rotates so that the upper protruding end thereof extends out of the disengagement groove, thereby punching the metal sheet on the driving plate 44. The upper end is limited. After the stamping is completed, the punch assembly 5 rises, and the driving plate 44 rises under the action of the telescopic rod 45. During the rising process, since the lower end of the limiting plate 484 is not squeezed, it is in an extended state. At this time, the sum of the height of the limiting plate 484, the height of the driving plate 44 and the thickness of the metal plate is greater than the diameter of the arc plate 483. The extended end of the upper part of the arc plate 483 limits the upper end of the metal plate (due to the upper limit of the arc plate 483, the driving plate 44 stops rising after rising to a certain height). After the driving plate 44 stops rising, the punch assembly 5 continues to rise. At this time, under the position limit of the upper end of the arc plate 483 on the metal plate, the metal plate is separated from the punch assembly 5. Subsequently, the die frame 43 is relatively translated and reset. Due to the translation of the die frame 43, the upper end of the arc plate no longer presses the workpiece after stamping (refer to Fig.11 ) is limited upward, driving the plate 44 to rise and reset at a low speed under the elastic action of the telescopic rod 45, and the collecting component 6 pushes and collects the fallen metal sheets. At the same time, the components of the separation mechanism 48 are reset.

[0046] See also Figure 8 As shown, the punch assembly 5 includes a cylinder 51, a punch 52, a support plate 53, a support block 54, a first component 55, a second component 56, an unlocking plate 59 and a linkage plate 50. The cylinder 51 is fixedly installed on the protective cover 11, and the support block 54 is fixedly installed on the ejection end of the cylinder 51. An unlocking groove is provided at the inner upper end of the support block 54. The support block 54 and the support plate 53 of the U-shaped structure are fixedly connected. The support plate 53 is slidably arranged in the cavity opened inside the punch 52, and adsorption holes are evenly opened at the lower end of the punch 52. The first component 55 is symmetrically arranged on the punch 52, and the second component 56 is arranged in the middle of the punch 52. A groove is opened on the punch 52, and the unlocking plate 59 slides left and right in the groove. A spring four is connected between the unlocking plate 59 and the groove, and the linkage plate 50 is fixedly installed on the unlocking plate 59.

[0047] In the above technical solution, after the metal sheet is cut, the punch 52 descends to absorb the metal sheet and rise until the metal sheet is higher than the die assembly 4, the die assembly 4 drives the upper die 31 to reset, and the cylinder 51 drives the support block 54 to move downward. When the punch 52 absorbs the metal sheet and enters the extrusion cavity of the die frame 43, the edge of the metal sheet is preliminarily folded and formed, and then the plate 44 is driven to continue to descend. The edge of the bent metal sheet squeezes the linkage plate 50, and the linkage plate 50 drives the unlocking plate 59 to move. After the preliminary forming of the metal sheet is completed, the upper end of the unlocking plate 59 is inserted into the unlocking groove of the support plate 53. At this time, the unlocking plate 59 no longer limits the height between the punch 52 and the support block 54, and the support block 54 continues to move downward. The punch 52 temporarily stops moving. At this time, the cylinder 51 drives the support plate 53 to push the first component 55 and the second component 56 to move outward. The first component 55 and the second component 56 cooperate with the correction die 461 to perform secondary forming on the metal sheet.

[0048] See also Figure 8 As shown, the first component 55 and the second component 56 are components with the same structure. The first component 55 includes an inclined rod 551, a limit block 552, a push block 553, a telescopic rod 554 and a stopper 555. The support plate 53 is provided with symmetrical sliding grooves, in which a slidable inclined rod 551 is arranged. The limit block 552 is fixedly installed on the inner side wall of the cavity of the punch 52. The limit block 552 is provided with symmetrical inclined grooves, through which the inclined rod 551 is fixedly installed with a push block 553. The punch 52 is provided with a re-push groove, which is connected to the cavity of the punch 52. Avoidance grooves are provided on both side walls of the re-push groove, in which a telescopic rod 554 is fixedly installed, and a stopper 555 is fixedly installed on the protruding end of the telescopic rod 554.

[0049] In the above technical solution, when the support plate 53 moves downward, the support plate 53 pushes the inclined rod 551 to drive the push block 553 to move outward, and the inclined groove of the limit block 552 guides the movement process of the inclined rod 551. As the push block 553 moves, the push block 553 squeezes the stop block 555 to make it move to both sides and retract into the avoidance groove, so that the push block 553 can extend outward from the punch 52, and the extended push block 553 cooperates with the extended correction mold 461 to complete the secondary forming of the metal sheet.

[0050] See also Figure 2 and Fig. 9As shown, the collecting assembly 6 includes a flap 61, an angle plate 62, an electric slider 63 and a collecting slide 64. An L-shaped groove is opened on the driving plate 44. The flap 61 is installed in the L-shaped groove through a pin shaft. The angle plate 62 is fixedly installed on the flap 61. The electric slider 63 is installed in the L-shaped groove. The electric slider 63 is connected to the angle plate 62 through a pin shaft. The collecting slide 64 is fixedly installed on the protective cover 11.

[0051] In the above technical solution, when the formed metal sheet is successfully detached from the driving plate 44, the electric slider 63 starts to move. During the movement of the electric slider 63, the electric slider 63 pushes the angle plate 62 so that the angle plate 62 is gradually adjusted, thereby pushing the flap 61 to rotate. As the flap 61 gradually rotates, the formed metal sheet slides into the collection slide 64 under the inclination of the flap 61, which facilitates the collection of the formed metal sheet.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
