In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] Combination Figures 1 to 4 As shown, this embodiment provides a processing device for electronic device pins, including a material strip feeding mechanism 1, a pin bending mechanism 2 and a discharge mechanism 3. Preferably, the electronic device in this embodiment can be set as a resistor device or a capacitor device with a longer pin. Further, for ease of understanding, the material strip and material parts referred to in this embodiment are respectively set as capacitor material strip and capacitor.

[0032] Specifically, the material tape feeding mechanism 1 in this embodiment includes an elastic clamping mechanism 11 and a material pushing mechanism matched with the elastic clamping mechanism 11 ; the elastic clamping mechanism 11 clamps the material tape 5 .

[0033] Furthermore, in the present embodiment, in order to facilitate the unfolding of the material belt 5, a material roller assembly 13 is further provided on the material feeding side of the material belt feeding mechanism 1. Specifically, the material roller assembly 13 includes a fixed plate 131 fastened to the workbench, and a material roller 132 vertically pivoted to a side wall of the fixed plate 131. The material rollers 132 are arranged in pairs so as to press the material belt tightly.

[0034] Furthermore, the pushing mechanism in this embodiment includes a first cylinder 121 arranged along the feeding direction of the material belt 5, and a pushing assembly connected to the first cylinder 121; the pushing assembly includes a slider 122 connected to the driving end of the first cylinder 121, a second cylinder 123 vertically mounted above the slider 122, a pressure plate 124 connected to the driving end of the second cylinder 123, and a lever 125 and a pressure rod 126 vertically fastened to the pressure plate 124.

[0035] Preferably, in the present embodiment, in order to reduce the friction between the pressure rod 126 and the elastic clamping mechanism 11 when the lever 125 pushes the material, a roller 127 is pivotally connected to the lower end of the pressure rod 126, that is, when the lever 125 is driven by the first cylinder 121 to push the material strip 5 forward to feed, the pressure rod 126 pressed on the elastic clamping mechanism 11 slides with the elastic clamping mechanism 11 through the roller 127.

[0036] Furthermore, the elastic clamping mechanism 11 in this embodiment includes an elastic base 111, a top block 112 that slides with the elastic base 111, a lower clamping plate 113 that slides with the top block 112, and an upper clamping plate 114 that is fastened to the top block 112, the lower clamping plate 113 is fastened to the elastic base 111, and the top block 112 and the elastic base 111 are both fastened to the workbench.

[0037] Preferably, the elastic base 111 in this embodiment includes a bottom plate 1111 horizontally arranged above the workbench, a guide sleeve 1112 vertically buried in the workbench, a first guide column 1113 slidingly matched with the guide sleeve 1112, and a spring 1114 sleeved on the first guide column 1113, the upper end of the first guide column 1113 is fastened to the lower bottom surface of the bottom plate 1111, wherein a plurality of guide rods are evenly distributed on the upper surface of the top block 112 along the length direction, the guide rods are slidingly matched with the slide grooves opened on the bottom plate 1111, the top end of the guide rod is vertically fastened with a pin fastened to the upper clamping plate 114, and the pin is slidingly matched with the lower clamping plate 113.

[0038] With the elastic clamping mechanism 11 designed with the above structure, when the pressure rod 126 in the pushing mechanism drives the bottom plate 1111 to move downward under the action of the second cylinder 123, the lower clamping plate 113 slides with the guide rod on the top block 112 and moves downward synchronously with the bottom plate 1111. Since the upper clamping plate 114 is fastened to the ejector pin arranged on the guide rod, the lower clamping plate 113 is separated from the upper clamping plate 114. After that, the lever 125 can be driven by the first cylinder 121 to push the material belt 5 forward for feeding. When the material belt 5 is pushed into place, the second cylinder 123 is reset, and the bottom plate 1111 is driven by the elastic force of the spring 1114 to move the bottom plate 1111 and the lower clamping plate 113 upward, thereby making the upper clamping plate 114 and the lower clamping plate 113 clamp the material belt 5. After that, the first cylinder 121 drives the lever 125 to reset, so as to facilitate the material belt 5 to enter the next feeding cycle.

[0039] Preferably, the elastic clamping mechanism 11 with the above-mentioned structural design is adopted. In order to facilitate the positioning of the material strip 5, a positioning groove 1131 for positioning the material strip 5 is recessed along the length direction on the upper surface of the lower clamping plate 113. Further preferably, in order to clamp the material strip 5 when the upper clamping plate 114 and the lower clamping plate 113 are closed, the depth of the positioning groove 1131 in this embodiment is less than the thickness of the material strip 5.

[0040] In addition, in order to facilitate the movement of the lever 125 in the feeding direction, the present embodiment has a clearance groove 1141 in the positioning groove 1131 and on the upper surface of the upper clamping plate 114 for the lever 125 to push the material belt 5 for feeding. The lever 125 is inserted into the material pushing hole on the material belt 5, and then moves along the clearance groove 1141 in the feeding direction of the material belt 5 under the driving action of the first cylinder 121, thereby realizing the forward feeding of the material belt 5.

[0041] Furthermore, in order to cooperate with the material belt feeding mechanism 1 and efficiently realize the separation of the material and the material belt 5, as well as the bending of the material pins, the present embodiment further provides a pin bending mechanism 2 on one side of the material belt feeding mechanism 1, and the pin bending mechanism 2 includes an upper mold 21, a lower mold 22, and a driving mechanism for opening and closing the upper mold 21 and the lower mold 22; specifically, the upper mold 21 includes an upper mold base 211, and a punch 212 fastened to the upper mold base 211; the lower mold 22 includes a lower mold base 221, a lower mold plate 222 mounted on the top of the lower mold base 221, a second guide column 223 vertically fastened around the lower mold plate 222, and a compression spring 224 sleeved on the second guide column 223 and with its two ends respectively abutting against the upper mold base 211 and the lower mold plate 222; the driving mechanism includes a bracket mounted on the workbench, and a third cylinder 23 mounted above the bracket, and the driving rod of the third cylinder 23 is fastened to the upper mold base 211. Preferably, in order to facilitate the collection of the material strip 5 after separation from the material parts, in this embodiment, a waste recovery hole is opened through the middle of the lower template 222 and the lower mold base 221. The waste recovery hole is connected to the through hole opened on the workbench, and a waste recovery box is arranged below the through hole.

[0042] With the pin bending mechanism 2 of the above structural design, when the elastic clamping mechanism 11 is closed, the material strip 5 stops feeding, and the driving mechanism drives the upper die 21 and the lower die 22 to close the mold, and then the material and the material strip 5 are separated and the pins of the material are bent by the punch 212; thereafter, when the elastic clamping mechanism 11 is opened, the driving mechanism drives the upper die 21 and the lower die 22 to open the mold, and the material strip 5 continues to feed, thereby entering the next cycle. In this embodiment, the specific structural design between the punch 212 and the lower mold plate 222 is relatively common in related stamping dies, and will not be described in detail here.

[0043] Furthermore, in this embodiment, in order to facilitate the transfer and storage of a single finished material, a discharge mechanism 3 is further provided on one side of the pin bending mechanism 2. Specifically, the discharge mechanism 3 includes a pneumatic clamp 31 provided on one side of the pin bending mechanism 2, a guide rail 32 slidably matched with the pneumatic clamp 31, and a fourth cylinder 33 for driving the pneumatic clamp 31 to move back and forth along the length direction of the guide rail 32. The guide rail 32 is provided along the feeding direction of the material belt 5, and a material receiving box 4 is provided on one side of the pneumatic clamp 31. In this way, under the driving action of the fourth cylinder 33, the separated and pin-formed material is transferred to the material receiving box 4 through the pneumatic clamp 31.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention.
