DETAILED DESCRIPTION

[0021] Embodiment 1:

[0022] See also Figures 1 to 6 An embodiment of the present invention provides a manufacturing device for an electrical connector, which is mainly used to achieve effective electroplating of a workpiece. The device includes a track 1 and a processing groove 2 located directly below the track 1. A central axis 3 is provided below the track 1, and a plurality of hanging rods 4 arranged in a circular array are provided on the outer surface of the central axis 3. When in use, the workpiece can be hung on the hanging rods 4 in turn to form a hanging plating method.

[0023] Furthermore, the track 1 is provided with a control component 5 for driving the central shaft 3 and the hanging rod 4 to move. Correspondingly, the control component 5 can drive the central shaft 3 to move back and forth in the vertical direction and in the horizontal direction. When moving in the vertical direction, the hanging rod 4 and the workpiece on the hanging rod 4 can be driven to fall into the processing tank 2, and the processing tank 2 performs electroplating processing. An adjustment component 6 is provided between the control component 5 and the central shaft 3. When the control component 5 drives the central shaft 3 to move toward the processing tank 2 and the adjustment component 6 contacts the bottom wall of the processing tank 2, the adjustment component 6 can drive the central shaft 3 and the hanging rod 4 to rotate by themselves, thereby improving the electroplating effect on the workpiece.

[0024] In this embodiment, the processing tank 2 can be specifically subdivided into a first electroplating tank, a cleaning tank, a second electroplating tank, and so on. That is to say, the processing tank 2 has multiple open grids from left to right. When the control component 5 drives the hanging rod 4 to descend into the corresponding open grid, the corresponding first electroplating, cleaning, and second electroplating processes can be formed; among them, the processing tank 2 and the hanging rod 4 are both existing mature technologies and will not be described in detail here.

[0025] Reference Figure 1 and Figure 2In this embodiment, preferably: the control component 5 includes a transverse cylinder 501 fixedly mounted on the track 1 and a base 502 slidably matched with the bottom of the track 1, the output shaft of the transverse cylinder 501 is fixedly connected to the base 502, which is driven by the transverse cylinder 501 and is used to place the adjustment component 6; a longitudinal cylinder 503 is fixedly mounted on the base 502, and the output shaft of the longitudinal cylinder 503 is fixedly mounted with a retaining frame 504 movably sleeved on the outer surface of the central axis 3.

[0026] In the above structure, the horizontal cylinder 501 is used to drive the base 502, the adjustment assembly 6 and the longitudinal cylinder 503 to move in the horizontal direction, and the longitudinal cylinder 503 drives the central axis 3 and the hanging rod 4 to move horizontally synchronously through the retaining frame 504. The longitudinal cylinder 503 can also drive the central axis 3 and the hanging rod 4 to move in the up-down direction through the retaining frame 504, thereby forming a relative approach / distance relative to the processing groove 2.

[0027] Reference Figures 2 to 5 In this embodiment, preferably, the adjustment component 6 includes a telescopic rod 601 fixedly connected to the base 502 and a guide rod 602 movably sleeved in the central axis 3, the bottom of the guide rod 602 extends from the bottom surface of the central axis 3, the telescopic rod 601 is divided into a fixed end 6011 and a movable end 6012, the fixed end 6011 is fixedly connected to the base 502 and the movable end 6012 is inserted into the central axis 3 and fixedly connected to the guide rod 602, a first spring 603 is fixedly installed between the top surface of the guide rod 602 and the inner wall of the central axis 3, the first spring 603 enables the guide rod 602 to maintain a state of extending from the bottom surface of the central axis 3, of course, the guide rod 602 is partially extended relative to the central axis 3.

[0028] Furthermore, a spiral groove 301 is provided on the inner wall of the central shaft 3 and an insert 604 slidably installed in the spiral groove 301 is fixedly installed on the outer surface of the guide rod 602. When the longitudinal cylinder 503 drives the central shaft 3 to descend through the retaining frame 504, the central shaft 3 can drive the guide rod 602 to descend synchronously so that the movable end 6012 of the telescopic rod 601 is further extended; when the guide rod 602 driven by the central shaft 3 contacts the bottom wall of the processing groove 2, the guide rod 602 can no longer move. At this time, the continued descent of the central shaft 3 causes the central shaft 3 to self-rotate through the insert 604 and the spiral groove 301. During this process, the telescopic rod 601 can be used to limit the guide rod 602 to prevent its self-rotation.

[0029] When in use, first hang the workpieces on the hanging rod 4 in turn, then start the longitudinal cylinder 503 to drive the central axis 3 and the guide rod 602 to descend through the retaining frame 504, and at this time, the movable end 6012 of the telescopic rod 601 descends synchronously with the guide rod 602; when the guide rod 602 contacts the bottom wall of the processing groove 2, the central axis 3 continues to descend and moves downward along the outer surface of the guide rod 602 (the first spring 603 is compressed). At this time, the central axis 3 can drive the hanging rod 4 and the workpiece to rotate in the processing groove 2 through the insert block 604 and the spiral groove 301, thereby improving the electroplating effect on the workpiece.

[0030] Then the longitudinal cylinder 503 drives the central shaft 3 to rise and reset through the retaining frame 504. At this time, the guide rod 602 is restored to the state of extending from the bottom surface of the central shaft 3 through the first spring 603, and the movable end 6012 is correspondingly retracted relative to the fixed end 6011. Then the transverse cylinder 501 is started to drive the base 502, the longitudinal cylinder 503 and the telescopic rod 601 to move horizontally synchronously, so that the central shaft 3 and the hanging rod 4 are translated along the processing groove 2. Finally, the longitudinal cylinder 503 is started to repeat the lifting and lowering steps of the central shaft 3.

[0031] As a further improvement of this embodiment: after the longitudinal cylinder 503 drives the central shaft 3 to rise and reset through the retaining frame 504, the telescopic rod 601 is in the limit state after contraction, that is, at this time, the movable end 6012 of the telescopic rod 601 can no longer contract relative to the fixed end 6011. At this time, if the longitudinal cylinder 503 continues to drive the central shaft 3 to rise, the movable end 6012 will resist the guide rod 602 so that it can no longer move, and then the central shaft 3 will rise along the outer surface of the guide rod 602 (the first spring 603 is stretched), and at this time, the central shaft 3 can drive the hanging rod 4 and the workpiece to rotate automatically through the insert block 604 and the spiral groove 301, and the self-rotation is located above the processing groove 2, which can avoid the accumulation of processing liquid on the hanging rod 4 and the workpiece, and avoid affecting the further processing of the next station of the processing groove 2.

[0032] Furthermore, a groove 302 for avoiding the fixed end 6011 can be opened at the top of the central shaft 3. When the longitudinal cylinder 503 drives the central shaft 3 to rise further, the central shaft 3 can receive the fixed end 6011 of the telescopic rod 601 through the groove 302 to avoid interference between the two.

[0033] In summary, through the coordination of the telescopic rod 601, the guide rod 602, the central axis 3 and the retaining frame 504, the workpiece can be driven to descend into the processing tank 2 to complete the processing, the workpiece can be driven to rotate in the processing tank 2 to improve the electroplating effect, and the workpiece can be driven to different open grids of the processing tank 2 to complete the overall electroplating processing. After the workpiece is raised and reset, it can also drive the workpiece to rotate by itself, avoiding the residual processing liquid on the hanging rod 4 and the workpiece, and avoiding the mutual influence of the processing liquids at different stations in the processing tank 2, which can further ensure the overall electroplating quality and reliability, and has higher practicality.

[0034] Embodiment 2: See also Figures 1 to 8 On the basis of the first embodiment, in order to further improve the electroplating effect on the workpiece, the bottom wall of the processing tank 2 extends upward to form an arc block 7, which is designed in an arc shape and has a high point and a low point. Correspondingly, after the longitudinal cylinder 503 drives the hanging rod 4 and the workpiece to descend into the processing tank 2 through the central axis 3, the guide rod 602 contacts the high point of the arc block 7 and corresponds to the high point position of the arc block 7; the transverse cylinder 501 can also be started to drive the hanging rod 4 and the workpiece to move a short distance in the horizontal direction, at which time the guide rod 602 moves along the high point of the arc block 7 to the low point.

[0035] In the above structure, when the guide rod 602 moves from the high point to the low point along the arc block 7, the vertical position of the central axis 3 remains unchanged because the longitudinal cylinder 503 is in an unactivated state, and the first spring 603 can make the guide rod 602 further descend relative to the central axis 3. At this time, the central axis 3 and the hanging rod 4 can be driven to rotate by themselves through the insert block 604 and the spiral groove 301.

[0036] When in use, through the structures such as the telescopic rod 601, the central axis 3 and the retaining frame 504, the workpiece can be driven to descend into the processing groove 2 and rotate in the processing groove 2 to improve the electroplating effect. After the workpiece rises and resets, the workpiece can also be driven to rotate automatically to avoid residual processing liquid. The working process and effect of this part are the same as those in the first embodiment, and will not be repeated here. The difference is that when the longitudinal cylinder 503 drives the central axis 3 and the guide rod 602 to descend, the guide rod 602 first contacts and is blocked by the high point of the arc block 7, and the central axis 3 continues to descend, which can drive the hanging rod 4 and the workpiece to rotate automatically in the processing groove 2. Then the transverse cylinder 501 starts to drive the longitudinal cylinder 503 and the telescopic rod 601 to move horizontally, so that the guide rod 602 moves from the high point of the arc block 7 to the low point in the processing groove 2. During the movement, because the upper and lower positions of the central axis 3 remain unchanged, the guide rod 602 can descend under the action of the first spring 603, thereby driving the central axis 3 and the hanging rod 4 to rotate automatically again through the insert block 604 and the spiral groove 301.

[0037] Compared with the first embodiment, through the coordination of the telescopic rod 601, the guide rod 602, the central axis 3 and the arc block 7, when the workpiece is lowered into the processing groove 2, the transverse cylinder 501 can be started to drive the workpiece to move horizontally in the processing groove 2, and the guide rod 602 moves from the high point to the low point of the arc block 7. In this process, the central axis 3 and the workpiece can be rotated again. Through multiple rotations and the horizontal movement of the workpiece, the electroplating effect of the workpiece can be further improved. The overall design is combined with the setting of the guide rod 602, and it will not affect the initial self-rotation of the workpiece after it is lowered into the processing groove 2, nor will it affect the self-rotation of the workpiece after it rises and resets (to avoid residual processing liquid), and it has stronger applicability.

[0038] Embodiment three: See also Figures 1 to 10 On the basis of the second embodiment, in order to further improve the electroplating effect on the workpiece, the hanging rod 4 is slidably matched with the central axis 3, and the hanging rod 4 slides correspondingly along the radial direction of the central axis 3. A second spring (not shown in the figure) is fixedly installed between the hanging rod 4 and the central axis 3. The second spring makes the hanging rod 4 tend to approach the central axis 3.

[0039] Furthermore, the outer surface of the central axis 3 is provided with a cavity 305 for slidingly placing a plurality of hanging rods 4, and a vertical plate 8 that is movably fitted with the central axis 3 is also slidably installed inside the cavity 305; wherein the vertical plate 8 slides along the axial direction of the central axis 3. Correspondingly, a protrusion 401 that abuts against the vertical plate 8 is fixedly installed at the end of the central axis 3 close to the vertical plate 8, and a slope 801 is provided at the position of the vertical plate 8 corresponding to the protrusion 401, and both the protrusion 401 and the slope 801 are designed in a side V shape; when the vertical plate 8 rises or falls, the hanging rod 4 can be driven away from the outside of the central axis 3 through the protrusion 401 and the slope 801, and the second spring is stretched.

[0040] In order to realize the vertical plate 8 to move up and down, a partition plate 605 fixedly connected to the guide rod 602 is fixedly installed on the surface of the vertical plate 8 away from the hanging rod 4. When the guide rod 602 moves correspondingly relative to the central shaft 3, the vertical plate 8 can be driven to rise and fall correspondingly through the partition plate 605. Correspondingly, a bottom groove 303 is provided inside the central shaft 3 for the placement of the guide rod 602 and the first spring 603. A sliding groove 304 connected to the bottom groove 303 and the cavity 305 is provided inside the central shaft 3. The sliding groove 304 is used to place the partition plate 605.

[0041] Furthermore, the slide groove 304 has a certain length along the radial direction of the central axis 3, so that when the guide rod 602 is raised or lowered relative to the central axis 3, the partition 605 has a certain lifting space in the slide groove 304; and the slide groove 304 also has a certain length along the circumferential direction of the central axis 3, so that when the central axis 3 rotates, the partition 605 also has a certain avoidance space in the slide groove 304.

[0042] When in use, the workpiece can be driven to descend into the processing groove 2 and can be driven to rotate after rising and resetting through the structures such as the telescopic rod 601, the central axis 3 and the retaining frame 504; the workpiece can be driven to move horizontally in the processing groove 2 so that the central axis 3 and the workpiece rotate again through the structures such as the telescopic rod 601, the central axis 3 and the arc block 7, and further improve the electroplating effect on the workpiece. The working process and effect of this part are the same as those in the first embodiment, and will not be repeated here. The difference is that: when the central axis 3 rises and falls correspondingly relative to the guide rod 602, the guide rod 602 drives the vertical plate 8 to rise and fall correspondingly in the cavity 305 through the partition 605, and the vertical plate 8 drives the hanging rod 4 to move away from the central axis 3 through the protrusion 401 and stretches the second spring. At this time, the hanging rod 4 drives the workpiece to move correspondingly along the radial direction of the central axis 3; when the vertical plate 8 is reset, the second spring can make the hanging rod 4 automatically reset along the central axis 3.

[0043] Compared with the second embodiment, through the cooperation of the guide rod 602, the partition plate 605, the vertical plate 8 and the protrusion 401, when the central axis 3 rises and falls correspondingly with respect to the guide rod 602, the hanging rod 4 and the workpiece can be driven to move back and forth along the radial direction of the central axis 3. The reciprocating movement in the processing tank 2 can further improve the electroplating effect on the workpiece, and the reciprocating movement after resetting can further avoid the residual processing liquid. The overall design is combined with the movement of the guide rod 602, which will not affect the self-rotation of the hanging rod 4 and the workpiece driven by the central axis 3, and has a promoting effect on the electroplating effect and the removal of the processing liquid, and has stronger functionality, meeting more needs in actual use.
