[0002] A aligning machine is an automated device used to arrange and organize parts or items. In the connector production process, aligning machines are usually needed to position the solder cups so that they can be soldered to complete the connector production process.

[0003] In the existing technology, the aligning machine used to position the solder cups can only distinguish between the large-diameter end and the small-diameter end of the solder cup and drive the small-diameter end of the solder cup to press down. However, it cannot effectively position the cup opening during the pressing process. This makes it easy to produce soldering failures or poor soldering quality in the subsequent soldering process, affecting the overall efficiency of connector production. Utility Model Content

[0009] A filler is disposed at the small-diameter end of the solder cup, and the filler has a through hole along the length direction of the solder cup;

[0010] A fastener is provided at the large-diameter end and can be fixed to the top plate. The fastener has a pre-insertion hole coaxial with the through hole.

[0011] A connecting pin is provided, which passes through the through hole and the pre-entry hole and extends out of the solder cup. A stepped joint is provided at the end of the connecting pin away from the large-diameter end.

[0014] Preferably, both the stepped joint and the contoured positioning pin are provided with a joint platform at their respective ends, and the joint platform is perpendicular to the length direction of the connecting pin.

[0015] Preferably, the connecting pin ring is provided with a plurality of pins, and the stepped joints on the plurality of connecting pins are oriented in a direction away from the axis of the solder cup.

[0016] Preferably, the diameter of the contour positioning pin is larger than the diameter of the connecting pin.

[0017] Preferably, the top plate is provided with a fixing hole, and the end of the fixing member away from the small diameter end is detachably fixed to the fixing hole.

[0018] Preferably, the side wall of the fastener is provided with a positioning groove, and the side wall of the filler is provided with a positioning block, the positioning block being able to extend into the positioning groove.

[0019] Preferably, the fastener includes an abutting portion and an extending portion, the extending portion extending into the large-diameter end, the diameter of the abutting portion being larger than the diameter of the large-diameter end, and used to abut and limit the movement against the end face of the large-diameter end.

[0021] On the other hand, this utility model provides a aligner, wherein the above-mentioned aligner positioning structure is used.

[0022] Beneficial effects:

[0023] This utility model provides a positioning structure for an alignment machine, comprising a top plate, solder cups, fillers, fixing members, connecting pins, and a base plate. The solder cups have a large-diameter end and a small-diameter end; the filler is located at the small-diameter end of the solder cup, and has a through hole along the length of the solder cup; the fixing member is located at the large-diameter end and can be fixed to the top plate, and has a pre-insertion hole coaxial with the through hole; the connecting pin passes through the through hole and the pre-insertion hole and extends out of the solder cup, with a stepped engagement portion at the end of the connecting pin away from the large-diameter end; the base plate has a contour positioning pin for engaging with the stepped engagement portion. Initially, a vibratory feeder can be used to guide the connecting pin into the through hole and the pre-insertion hole to install the connecting pin in the solder cup. After the connecting pin is installed, multiple solder cups can be connected to the top plate, and then the top plate drives multiple solder cups to press down and engage with the contour positioning pin. During the engagement process, the stepped engagement portion is subjected to the reaction force of the contour positioning pin to calibrate the positioning accuracy.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0034] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0036] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0037] like Figures 1-7As shown, this embodiment provides a positioning structure for an alignment machine, which includes a top plate 1, a solder cup 2, a filler 3, a fixing member 4, a connecting pin 5, and a bottom plate 6. The positioning mechanism of the alignment machine requires the solder cup 2 to be placed on the top plate 1, and the solder cup 2 is positioned so that its position corresponds to that of the bottom plate 6 by moving the top plate 1. The top plate 1 is used to set multiple solder cups 2 and drive the multiple solder cups 2 to approach the bottom plate 6. The solder cup 2 includes a large-diameter end and a small-diameter end, wherein the small-diameter end is used to approach the bottom plate 6. The filler 3 is set at the small-diameter end of the solder cup 2, and the filler 3 is provided with a through hole 31 along the length direction of the solder cup 2. The fixing member 4 is set at the large-diameter end and can be fixed to the top plate 1. The fixing member 4 is provided with a pre-entry hole 41 coaxial with the through hole 31. The connecting pin 5 passes through the through hole 31 and the pre-entry hole 41 and extends out of the solder cup 2. The end of the connecting pin 5 away from the large-diameter end is provided with a stepped engagement part. The connecting pin 5 is also called a PIN pin, or a spring pin, battery pin, etc. It is an important component in the connector and serves as a contact to realize the electrical connection between the connector and the outside. The bottom plate 6 is provided with a contoured positioning pin 61. The contoured positioning pin 61 and the stepped engagement part have complementary shapes. The contoured positioning pin 61 is used to engage with the stepped engagement part.

[0038] Specifically, initially, a vibratory feeder can be used to guide the connecting pin 5 into the through hole 31 and the pre-insertion hole 41 to install the connecting pin 5 into the solder cup 2. After the connecting pin 5 is installed, multiple solder cups 2 can be connected to the top plate 1, and then the top plate 1 drives the multiple solder cups 2 to press down and engage with the contour positioning pin 61. During the engagement process, the stepped engagement part will be subjected to the reaction force of the contour positioning pin 61 to calibrate the positioning accuracy. After pressing down, the solder cup 2 can be accurately positioned. That is, the above-mentioned alignment machine positioning mechanism can effectively ensure that the solder cup 2 can be accurately positioned for the next process when using the alignment machine to produce connectors.

[0039] Specifically, in this embodiment, both the stepped joint and the contour positioning pin 61 are provided with guide surfaces 7. With the assistance of the vibratory feeder, the connecting pin 5 enters the pre-entry hole 41, ensuring the stepped joint has a fixed orientation for engagement with the contour positioning pin 61. However, the connecting pin 5 and the contour positioning pin 61 may still have a certain orientation deviation or positional offset at the start of engagement. A guide surface 7 is provided in the engagement surface between the stepped joint and the contour positioning pin 61. The guide surface 7 is an arc-shaped surface, and the tangent direction at any point on this arc-shaped surface forms an acute angle with the length direction of the connecting pin 5. During the engagement process, if a small misalignment occurs between the stepped joint and the contour positioning pin 61, the arc-shaped surface can ensure that the stepped joint is subjected to the elastic force generated by the arc-shaped surface during the pressing process, thereby ensuring the pressing direction so that the connecting pin 5 and the contour positioning pin 61 are aligned and connected. In some other embodiments, the guide surface 7 can also be an inclined plane, forming an acute angle with the length direction of the connecting pin 5.

[0040] Furthermore, in this embodiment, both the stepped joint and the end of the contour positioning pin 61 that are close to each other are provided with a joint platform 8, which is perpendicular to the length direction of the connecting pin 5. When the top plate 1 pushes the connecting pin 5 down, it provides a downward pressure along its length direction to the connecting pin 5. During the engagement process between the connecting pin 5 and the contour positioning pin 61, a force and a reaction force perpendicular to the joint surface are generated between the connecting pin 5 and the contour positioning pin 61. If the joint surface is a slope or arc surface at this time, the connecting pin 5 will have a radial component force under the action of the downward pressure. If the component force is large, it is easy to cause the connecting pin 5 to bend, thereby affecting the electrical connection effect of the connecting pin 5. The joint platform 8, which is perpendicular to the length direction of the connecting pin 5, is beneficial to the connecting pin 5 to stop quickly after reaching the fixed position by the axial force provided by the joint platform 8, and to prevent the connecting pin 5 from bending under the action of the radial component force.

[0041] Furthermore, in this embodiment, the diameter of the contour positioning pin 61 is larger than the diameter of the connecting pin 5. The larger diameter of the contour positioning pin 61 is beneficial for increasing the size of its own guide surface 7 and engagement platform 8. The guide surface 7 and engagement platform 8 with larger areas are more likely to make contact with the relevant positions of the connecting pin 5 and realize the preset function.

[0042] Furthermore, in this embodiment, multiple connecting pins 5 are provided, and the stepped joints on the multiple connecting pins 5 face away from the axis of the solder cup 2. When the top plate 1 is pressed down, the connecting pins 5 may have a certain orientation deviation or positional deviation. If this is not corrected, it will easily lead to abnormal positioning of the solder cup 2. The setting of a single set of stepped joints and contour positioning pins 61 can only ensure that the connecting pins 5 are accurately positioned in one horizontal direction. With multiple connecting pins 5 arranged in a ring, and the stepped joints facing away from the axis of the connecting pins 5, the joint surfaces of multiple sets of stepped joints and contour positioning pins 61 can apply multiple sets of forces pointing towards the axis of the solder cup 2 to the multiple connecting pins 5 from different positions, ensuring the positioning effect of the solder cup 2. It can be understood that when installing the connecting pins 5, the vibration of the vibratory plate can make each connecting pin 5 have an appropriate angle.

[0043] Specifically, in this embodiment, the top plate 1 is provided with a fixing hole, and the end of the fixing member 4 away from the small-diameter end is detachably fixed to the fixing hole. The top plate 1 is a body cavity plate, and the fixing hole of the top plate 1 can realize the fixing of the fixing member 4. The fixing member 4 is set at the large-diameter end of the solder cup 2. After the top plate 1 fixes the fixing member 4 through the fixing hole, the fixing member 4 can drive the solder cup 2 to move downward as a whole. It can be understood that the fixing member 4 is not a component inside the finished connector, but only serves as an auxiliary transition part. Therefore, the fixing member 4 is detachably fixed to the fixing hole. After the solder cup 2 is processed, the fixing member 4 can be removed from the solder cup 2 and the top plate 1 and enter the production process of the next batch of solder cup 2, avoiding the waste caused by the fixing member 4 being left in the top plate 1 and the need to produce new fixing members 4 and the top plate 1. Furthermore, the cross-section of the end of the fixing member 4 away from the small-diameter end is a non-circular geometric shape, and the fixing hole also has a similar cross-sectional shape. When the fixing part 4 is set in the fixing hole, it can ensure that there will be no relative rotation, thereby avoiding the positioning deviation caused by the rotation of the solder cup 2 and the connecting pin 5, and ensuring the positioning effect.

[0044] Specifically, in this embodiment, the side wall of the fixing member 4 is provided with a positioning groove 42, and the side wall of the filling member 3 is provided with a positioning block 32, which can extend into the positioning groove 42. The filling member 3 is provided with a through hole 31, and the fixing member 4 is provided with a pre-insertion hole 41. The connecting pin 5 needs to pass through both the pre-insertion hole 41 and the through hole 31. Therefore, the pre-insertion hole 41 and the through hole 31 need to maintain a one-to-one correspondence to ensure the insertion of the connecting pin 5 and to prevent the pin body from bending due to misalignment between the pre-insertion hole 41 and the through hole 31 after insertion. The cooperation between the positioning groove 42 and the positioning block 32 ensures that the through hole 31 and the pre-insertion hole 41 correspond one-to-one and maintain a continuous corresponding state, facilitating the installation of the connecting pin 5.

[0045] Specifically, the fixing member 4 includes an abutting portion 43 and an extending portion 44. The extending portion 44 extends into the large-diameter end, and the diameter of the abutting portion 43 is larger than the diameter of the large-diameter end, serving to abut and limit contact with the end face of the large-diameter end. The fixing member 4 needs to achieve relative fixation with the solder cup 2 to facilitate the movement of the solder cup 2. Therefore, the extending portion 44 extends into and connects with the large-diameter end. At the same time, the abutting portion 43 prevents the extending portion 44 from extending too deeply, thus affecting the setting of the filler 3.

[0046] Furthermore, a limiting groove is provided on the side of the abutment part 43 near the large-diameter end, and the large-diameter end extends into the limiting groove. The large-diameter end extending into the limiting groove means that the mouth of the solder cup 2 extends into the limiting groove. The limiting groove can prevent the solder cup 2 from wobbling radially relative to the fixing part 4, and ensure the positional accuracy of the solder cup 2 during the pressing process.

[0047] Specifically, this embodiment provides an alignment machine that uses the above-described alignment machine positioning structure. This alignment machine can ensure the positioning accuracy of the solder cup 2, thereby improving the production efficiency of the connector.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
