Description

Technical Field

[0001] The utility model relates to the technical field of production and processing of electronic components, in particular to a tool for removing pins from electronic components. Background Art

[0002] like Figure 1 As shown, electronic components (such as electronic chips or network transformers, etc.) are usually provided with two rows of pins 21, and the two rows of pins 21 are connected together through a shell 20 that has been injection molded and electroplated. During the production process of electronic components, the pins 21 on the same side of multiple electronic components are simultaneously connected to the same pin connecting piece 22. In order to obtain individual electronic components, the pins 21 of the electronic components need to be separated from the pin connecting piece 22.

[0003] Currently, the method of separating the pins of electronic components from the pin connectors is mostly to break them off manually, which is time-consuming, labor-intensive and has low work efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide an electronic component pin removal tool, which can automatically and repeatedly break off the pin connecting pieces on the electronic components, is easy to use and has high working efficiency.

[0005] In order to solve the above technical problems, the present invention adopts the following solutions:

[0006] A tool for removing pins from electronic components comprises a frame, a bidirectional screw mounted on the frame, the bidirectional screw being connected to a drive motor, and two oppositely rotating threads on the bidirectional screw each being threadedly connected to a translating member. The two translating members are arranged opposite each other, and the translating members are provided with a vertical piece for prying the pins outward and a horizontal piece for prying the pins inward, with a pin gap between the vertical piece and the horizontal piece being provided for the pins to enter. The drive motor itself is prior art and will not be described in detail. The tool is configured to position the pin connector within the pin gap between the vertical piece and the horizontal piece when separating the electronic components. The vertical piece can be used to pry the pin connector from the inside out, and the horizontal piece can be used to pry the pin connector from the outside in. The bidirectional screw can simultaneously drive the translating members to move relative to or towards each other. By controlling the forward and reverse rotation of the bidirectional screw, the vertical piece can bend the pin connector outward and the horizontal piece can bend the pin connector inward. After repeated prying, the pin connector can be separated from the pins of the electronic component.

[0007] Furthermore, the frame is provided with a guide rail arranged parallel to the axis of the bidirectional screw, and the bottom surface of the translator is provided with a guide groove for nesting in the guide rail. The guide rail and the guide groove serve to guide the translator when the bidirectional screw drives the translator to move back and forth in the axial direction of the bidirectional screw and prevent the translator from rotating around the bidirectional screw.

[0008] Furthermore, the vertical pieces on the two translating members are positioned adjacent to each other, and a discharge port communicating with the pin gap is provided on the side of the translating member facing away from the vertical pieces. The two vertical pieces are positioned between the two pin gaps, which are in turn positioned between the two transverse pieces. The discharge port allows broken pin connectors to be discharged through the discharge port.

[0009] Furthermore, the translating member includes a mounting plate vertically mounted on the top edge of the translating member, a foot remover is mounted on the mounting plate, and the vertical piece, horizontal piece, pin gap, and discharge port are all mounted on the foot remover. The mounting plate serves to secure the foot remover to the translating member.

[0010] Furthermore, the de-legged member is provided with a mounting groove for receiving the mounting plate. When the mounting plate is inserted into the mounting groove, the distance between the surface of the mounting plate facing away from the discharge port and the surface where the discharge port is located is less than or equal to the distance between the surface of the de-legged member facing away from the discharge port and the surface where the discharge port is located. This arrangement of the mounting groove and the thickness relationship between the mounting plate and the mounting groove minimizes the spacing between the two de-legged members, thereby accommodating electronic components with closely spaced pins in two rows.

[0011] Furthermore, the mounting plate is thinner than the de-legged member, and the mounting plate and de-legged member are connected by bolts. The de-legged member is provided with a through hole for the bolt to pass through, and the mounting plate is provided with a threaded hole for threaded connection with the bolt. The through hole and the threaded hole are coaxially arranged. This serves to enable bolt connection between the mounting plate and the de-legged member by adjusting the mounting plate dimensions.

[0012] Furthermore, the foot removal member includes an outer breaking member and an inner breaking member that are sequentially arranged in a direction away from the mounting plate. The vertical piece is arranged on the outer breaking member and is arranged parallel to the mounting plate. The horizontal piece is arranged on the inner breaking member and is arranged perpendicular to the mounting plate. The top surface of the whole formed by the pin gap and the discharge port is arranged on the inner breaking member, and the bottom surface of the whole formed by the pin gap and the discharge port is arranged on the outer breaking member. The extension direction of the pin gap is the same as the extension direction of the vertical piece. The width of the outer breaking member in the section where the discharge port is located gradually increases from top to bottom. Its function is that, since it is difficult to directly open the pin gap and the discharge port in a whole, the arrangement of the inner breaking member and the outer breaking member facilitates the formation of the pin gap and the discharge port, thereby facilitating production and manufacturing.

[0013] Furthermore, the bottom surface of the outer breaking piece, which serves as the pin gap and the discharge port, is in a downwardly inclined arc shape. Its function is to facilitate the direct discharge of the broken pin connecting piece through the design of the shape of the outer breaking piece.

[0014] Furthermore, the inner breaking piece is provided with mounting posts on the left and right sides of the discharge port, and the mounting posts are connected to the outer breaking piece by bolts. Its function is to facilitate the stable connection between the inner breaking piece and the outer breaking piece through the provision of the mounting posts.

[0015] Furthermore, the horizontal piece and the vertical piece are provided with chamfers at the left and right ends of the pin gap, which is used to facilitate insertion of the pin connector with electronic components.

[0016] The utility model has the beneficial effects:

[0017] 1. When separating electronic components, the pin connector is located in the pin gap between the vertical piece and the horizontal piece. The vertical piece can be used to bend the pin connector from the inside to the outside, and the horizontal piece can be used to bend the pin connector from the outside to the inside. The bidirectional screw can simultaneously drive the translation member to move relative to or toward each other. By controlling the forward and reverse rotation of the bidirectional screw, the vertical piece can be used to bend the pin connector outward and the horizontal piece can be used to bend the pin connector inward. After repeated bending, the pin connector can be separated from the pin of the electronic component.

[0018] 2. The guide rail and the guide groove can guide and prevent the translation member from rotating around the bidirectional screw when the bidirectional screw drives the translation member to move back and forth in the axial direction of the bidirectional screw.

[0026] Example 1

[0027] An electronic component removal tool, such as Figure 2 As shown, the frame 1 includes a bidirectional screw 2 provided on the frame 1, the bidirectional screw 2 being connected to a drive motor 3. A translation member 4 is threadedly connected to each of the two oppositely rotating threads on the bidirectional screw 2. The two translation members 4 are arranged opposite each other. The translation members 4 are provided with a vertical piece 5 for bend the pins outward and a horizontal piece 6 for bend the pins inward. A pin gap 7 is left between the vertical piece 5 and the horizontal piece 6 for the pin 21 to enter. The drive motor 3 itself is prior art and will not be described in detail. Its function is to make the pin connecting piece 22 be located in the pin gap 7 between the vertical piece 5 and the horizontal piece 6 when separating the electronic components. Through the setting of the vertical piece 5, the pin 21 connector can be bent from the inside to the outside, and through the setting of the horizontal piece 6, the pin 21 connector can be bent from the outside to the inside. Through the setting of the bidirectional screw 2, the translation part 4 can be driven to move relative or toward each other at the same time. By controlling the forward and reverse rotation of the bidirectional screw 2, the vertical piece 5 can bend the pin 21 connector outward and the horizontal piece 6 can bend the pin 21 connector inward. After repeated bending, the pin 21 connector can be separated from the pin 21 of the electronic component.

[0028] Specifically, such as Figure 2As shown, the frame 1 is provided with a guide rail 8 arranged parallel to the axis of the bidirectional screw 2, and the bottom surface of the translation member 4 is provided with a guide groove 9 for being nested in the guide rail 8. The function of the guide rail 8 and the guide groove 9 is to guide and prevent the translation member 4 from rotating around the bidirectional screw 2 when the bidirectional screw 2 drives the translation member 4 to move back and forth in the axial direction of the bidirectional screw 2.

[0029] Specifically, such as Figure 2 As shown, the vertical pieces 5 on the two translating members 4 are positioned adjacent to each other. A discharge port 10 is provided on the side of the translating member 4 facing away from the vertical pieces 5, communicating with the pin gaps 7. The two vertical pieces 5 are positioned between the two pin gaps 7, which are in turn positioned between the two transverse pieces 6. The discharge port 10 allows the broken pin connector 22 to be discharged through the discharge port 10.

[0030] Specifically, such as Figure 3 As shown, the translating member 4 includes a mounting plate 11 vertically mounted on the top edge of the translating member 4. A foot remover 12 is mounted on the mounting plate 11. The vertical piece 5, horizontal piece 6, pin gap 7, and discharge port 10 are all mounted on the foot remover 12. The mounting plate 11 secures the foot remover 12 to the translating member 4.

[0031] Specifically, such as Figure 3 As shown, the de-leg piece 12 is provided with a mounting groove 13 for embedding into the mounting plate 11. When the mounting plate 11 is embedded in the mounting groove 13, the distance between the surface of the mounting plate 11 facing away from the discharge port 10 and the surface where the discharge port 10 is located is equal to the distance between the surface of the de-leg piece 12 facing away from the discharge port 10 and the surface where the discharge port 10 is located. This serves the purpose of minimizing the spacing between the two de-leg pieces 12 through the arrangement of the mounting groove 13 and the thickness relationship between the mounting plate 11 and the mounting groove 13, thereby accommodating electronic components with closely spaced rows of pins 21.

[0032] Specifically, such as Figure 3 As shown, the thickness of the mounting plate 11 is smaller than that of the foot-removing member 12. The mounting plate 11 and foot-removing member 12 are connected by bolts. The foot-removing member 12 is provided with a through hole 14 for the bolt to pass through, and the mounting plate 11 is provided with a threaded hole 15 for threaded connection with the bolt. The through hole 14 and the threaded hole 15 are arranged coaxially. The purpose of this is to enable the mounting plate 11 and foot-removing member 12 to be bolted together by setting the size of the mounting plate 11.

[0033] Specifically, such as Figure 3As shown, the foot removal member 12 includes an outer breaking member 16 and an inner breaking member 17, which are sequentially arranged in a direction away from the mounting plate 11. The vertical piece 5 is arranged on the outer breaking member 16 and is arranged parallel to the mounting plate 11. The horizontal piece 6 is arranged on the inner breaking member 17 and is arranged perpendicular to the mounting plate 11. The top surface of the whole formed by the pin gap 7 and the discharge port 10 is arranged on the inner breaking member 17, and the bottom surface of the whole formed by the pin gap 7 and the discharge port 10 is arranged on the outer breaking member 16. The extension direction of the pin gap 7 is the same as the extension direction of the vertical piece 5. The width of the outer breaking member 16 in the section where the discharge port 10 is located gradually increases from top to bottom. Its function is that, since it is difficult to directly open the pin gap 7 and the discharge port 10 in a whole, the arrangement of the inner breaking member 17 and the outer breaking member 16 facilitates the formation of the pin gap 7 and the discharge port 10, which is convenient for production and manufacturing.

[0034] Specifically, such as Figure 3 As shown, the bottom surface of the outer breaking piece 16, which is the whole of the pin gap 7 and the discharge port 10, is in a downwardly inclined arc shape. Its function is to facilitate the direct discharge of the broken pin connecting piece 22 through the design of the shape of the outer breaking piece 16.

[0035] Specifically, such as Figure 3 As shown, the inner breaking piece 17 is provided with mounting posts 18 on the left and right sides of the discharge port 10, and the mounting posts 18 are connected to the outer breaking piece 16 by bolts. Its function is to facilitate the stable connection of the inner breaking piece 17 and the outer breaking piece 16 by the setting of the mounting posts 18.

[0036] Specifically, such as Figure 3 As shown, the horizontal piece 6 and the vertical piece 5 are provided with a clearance chamfer 19 at the left and right ends of the pin gap 7. Its function is to facilitate the insertion of the pin 21 connector with electronic components through the setting of the clearance chamfer 19.

[0037] The working principle of this embodiment is described as follows: first, clamp the outer shell 20 of the electronic component, and extend the electronic component with the pin connecting piece 22 into the pin gap 7. Each pin connecting piece 22 is arranged in a pin gap 7. Then start the drive motor 3 to drive the bidirectional screw 2 to rotate forward and reverse repeatedly. When the bidirectional screw 2 rotates forward, the two translation parts 4 separate from each other, and the vertical piece 5 bends the pin connecting piece 22 to flip outward. Then, when the bidirectional screw 2 rotates forward, the two translation parts 4 approach each other, and the horizontal piece 6 bends the pin connecting piece 22 to flip inward. After repeated forward and reverse bending, the pin connecting piece 22 is separated from the pin 21 and falls out from the discharge port 10.

[0038] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Based on the technical essence of the present invention and within the spirit and principles of the present invention, any simple modification, equivalent replacement and improvement of the above embodiment shall still fall within the scope of protection of the technical solution of the present invention.
