DETAILED DESCRIPTION

[0031] Example one:

[0032] Referring to Figures 1 to 6 The manufacturing device of the electric connector provided by the embodiment of the present application is mainly used for realizing effective electroplating of workpieces. The device comprises a track 1 and a processing groove 2 located directly below the track 1. The lower portion of the track 1 is provided with a central shaft 3. The outer surface of the central shaft 3 is provided with a plurality of hanging rods 4 arranged in a ring array. In use, the workpieces can be hung on the hanging rods 4 in sequence, forming a hanging plating mode.

[0033] Further, the track 1 is provided with a control assembly 5 for driving the central shaft 3 and the hanging rods 4 to move. Correspondingly, the control assembly 5 can drive the central shaft 3 to reciprocate in the upward and downward directions and the horizontal direction. When moving in the upward and downward directions, the control assembly 5 can drive the hanging rods 4 and the workpieces on the hanging rods 4 to fall into the processing groove 2, and the processing groove 2 is used for electroplating processing. The control assembly 5 and the central shaft 3 are jointly provided with an adjusting assembly 6. When the control assembly 5 drives the central shaft 3 to move towards the processing groove 2 and the adjusting assembly 6 contacts the bottom wall of the processing groove 2, the adjusting assembly 6 can drive the central shaft 3 and the hanging rods 4 to rotate, thereby improving the electroplating effect of the workpieces.

[0034] In the embodiment, the processing groove 2 can be specifically subdivided into a first electroplating groove, a cleaning groove and a second electroplating groove, etc. That is, the processing groove 2 has a plurality of open grids from left to right. When the control assembly 5 drives the hanging rods 4 to descend into the corresponding open grid, corresponding first electroplating, cleaning and second electroplating processing can be formed. The processing groove 2 and the hanging rods 4 are both existing mature technologies, and will not be described in detail here.

[0035] Referring to Figure 1 and Figure 2In the embodiment, preferably, the control assembly 5 comprises a lateral cylinder 501 fixedly installed on the track 1 and a base 502 in sliding fit with the bottom of the track 1, the output shaft of the lateral cylinder 501 is fixedly connected with the base 502, which is driven by the lateral cylinder 501 and used for arranging the adjusting assembly 6; the base 502 is fixedly installed with a longitudinal cylinder 503, the output shaft of the longitudinal cylinder 503 is fixedly installed with a retainer 504 movably sleeved on the outer surface of the central shaft 3.

[0036] In the above structure, the lateral cylinder 501 is used for driving the base 502, the adjusting assembly 6 and the longitudinal cylinder 503 to move in the horizontal direction, the longitudinal cylinder 503 drives the central shaft 3 and the hanging rod 4 to synchronously move in the horizontal direction through the retainer 504 when moving. The longitudinal cylinder 503 can also drive the central shaft 3 and the hanging rod 4 to move in the vertical direction through the retainer 504, so as to relatively approach / far away from the processing groove 2.

[0037] With reference to Figures 2 to 5 In the embodiment, preferably, the adjusting assembly 6 comprises a telescopic rod 601 fixedly connected with the base 502 and a guide rod 602 movably sleeved in the central shaft 3, the bottom of the guide rod 602 is extended from the bottom surface of the central shaft 3, the telescopic rod 601 is divided into a fixed end 6011 and a movable end 6012, the fixed end 6011 is fixedly connected with the base 502 and the movable end 6012 is inserted into the central shaft 3 and fixedly connected with 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 shaft 3, the first spring 603 makes the guide rod 602 keep the state of being extended from the bottom surface of the central shaft 3, of course, the guide rod 602 is partially extended relative to the central shaft 3.

[0038] Further, the inner wall of the central shaft 3 is provided with a spiral groove 301 and the outer surface of the guide rod 602 is fixedly installed with an embedded block 604 movably installed in the spiral groove 301, when the longitudinal cylinder 503 drives the central shaft 3 to descend through the retainer 504, the central shaft 3 can drive the guide rod 602 to synchronously descend 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 with the bottom wall of the processing groove 2 and cannot be moved any more, the continuous descent of the central shaft 3 makes the central shaft 3 rotate through the embedded block 604 and the spiral groove 301, in the process, the telescopic rod 601 can be used for limiting the guide rod 602 to avoid the rotation of the guide rod 602.

[0039] In use, first, the workpiece is hung on the hanging rod 4 in turn, and then the longitudinal cylinder 503 is started to drive the center shaft 3 and the guide rod 602 to descend through the holder 504, at this time, the movable end 6012 of the telescopic rod 601 is lowered synchronously with the guide rod 602; when the guide rod 602 contacts the bottom wall of the processing groove 2, the center shaft 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 center shaft 3 can drive the hanging rod 4 and the workpiece to rotate in the processing groove 2 through the embedding block 604 and the spiral groove 301, thereby improving the electroplating effect on the workpiece.

[0040] Then the longitudinal cylinder 503 is started to drive the center shaft 3 to ascend and reset through the holder 504, at this time, the guide rod 602 is restored to the state of partially protruding from the bottom surface of the center shaft 3 through the first spring 603, and the movable end 6012 is correspondingly retracted relative to the fixed end 6011. Then the horizontal 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 center shaft 3 and the hanging rod 4 translate along the processing groove 2, and finally the longitudinal cylinder 503 is started to repeat the ascending and descending steps of the center shaft 3.

[0041] As a further improvement of the embodiment: when the longitudinal cylinder 503 drives the center shaft 3 to ascend and reset through the holder 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 cannot be retracted relative to the fixed end 6011. At this time, if the longitudinal cylinder 503 continues to drive the center shaft 3 to ascend, the movable end 6012 will abut against the guide rod 602 so that it cannot move any more, thereby making the center shaft 3 ascend along the outer surface of the guide rod 602 (the first spring 603 is stretched), at this time, the center shaft 3 can drive the hanging rod 4 and the workpiece to rotate again through the embedding block 604 and the spiral groove 301, and the 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.

[0042] Further, a groove 302 for avoiding the fixed end 6011 can be formed on the top of the center shaft 3, when the longitudinal cylinder 503 drives the center shaft 3 to further ascend, the center shaft 3 can accommodate the fixed end 6011 of the telescopic rod 601 through the groove 302, avoiding interference between the two.

[0043] In summary, through the cooperation of the telescopic rod 601, the guide rod 602, the center shaft 3 and the holder 504, the workpiece can be driven to descend into the processing groove 2 to complete the processing, and the workpiece can also be driven to rotate in the processing groove 2 to improve the electroplating effect, and the workpiece can also be driven to different open grids of the processing groove 2 to complete the overall electroplating processing. After the workpiece is raised and reset, the workpiece can also be driven to rotate, avoiding the residual processing liquid on the hanging rod 4 and the workpiece, avoiding the mutual influence of the processing liquids in different stations of the processing groove 2, which can further ensure the reliable electroplating quality and higher practicability.

[0044] Embodiment two:

[0045] Please refer to Figures 1 to 8 , on the basis of embodiment one, in order to further improve the plating effect of workpiece, the bottom wall of processing tank 2 extends upward to form arc block 7, arc block 7 is arc design and has high point and low point. Correspondingly, after the longitudinal cylinder 503 drives the hanging rod 4 and the workpiece to drop into the processing tank 2 through the center shaft 3, the guide rod 602 is in contact with the high point of the arc block 7, and corresponds to the high point position of the arc block 7; The horizontal cylinder 501 can also be started to drive the hanging rod 4 and the workpiece to move a small distance in the horizontal direction, at this time the guide rod 602 moves along the high point of the arc block 7 to the low point.

[0046] In the above structure, when the guide rod 602 moves along the high point of the arc block 7 to the low point, because the longitudinal cylinder 503 is in the state of not starting, the up and down position of the center shaft 3 remains unchanged, and the first spring 603 can make the guide rod 602 further drop relative to the center shaft 3, at this time the center shaft 3 and the hanging rod 4 can be driven to rotate again through the embedded block 604 and the spiral groove 301.

[0047] In use, through the telescopic rod 601, the center shaft 3 and the retainer 504 and other structures, the workpiece can be driven to drop into the processing tank 2 and rotate in the processing tank 2 to improve the plating effect, and after the workpiece rises to reset, it can also drive the workpiece to rotate to avoid the residual processing liquid, the part of the working process and effect is same with embodiment one, which is not repeated here. The difference is that when the longitudinal cylinder 503 drives the center shaft 3 and the guide rod 602 to drop, the guide rod 602 first contacts and is blocked by the high point of the arc block 7, and the center shaft 3 continues to drop to drive the hanging rod 4 and the workpiece to rotate in the processing tank 2. Then the horizontal cylinder 501 is started to drive the longitudinal cylinder 503 and the telescopic rod 601 to move horizontally, so that the guide rod 602 moves along the high point of the arc block 7 to the low point in the processing tank 2, and in the moving process, because the up and down position of the center shaft 3 does not change, the guide rod 602 can drop under the action of the first spring 603, so as to drive the center shaft 3 and the hanging rod 4 to rotate again through the embedded block 604 and the spiral groove 301.

[0048] Compared with the first embodiment, through the cooperation of the telescopic rod 601, the guide rod 602, the central shaft 3 and the arc block 7, when the workpiece is lowered into the machining groove 2, the horizontal cylinder 501 can be started to drive the workpiece to move horizontally in the machining groove 2, and the guide rod 602 is moved from the high point to the low point of the arc block 7. In this process, the central shaft 3 and the workpiece can be rotated again. Through multiple rotations combined with the horizontal movement of the workpiece, the electroplating effect on the workpiece can be further improved. The overall design is combined with the setting of the guide rod 602, and does not affect the preliminary rotation of the workpiece after it is lowered into the machining groove 2, nor does it affect the rotation of the workpiece after it is raised and reset (to avoid residual machining liquid), so the applicability is stronger.

[0049] The third embodiment is as follows:

[0050] Please refer to 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 in sliding cooperation with the central shaft 3, and the hanging rod 4 slides along the radial direction of the central shaft 3. A second spring (not shown in the figure) is fixedly installed between the hanging rod 4 and the central shaft 3, and the second spring makes the hanging rod 4 have a tendency to approach the central shaft 3.

[0051] Further, the outer surface of the central shaft 3 is provided with a cavity 305 for slidingly arranging a plurality of hanging rods 4. A vertical plate 8 is slidably installed in the cavity 305 and is in movable cooperation with the central shaft 3. The vertical plate 8 slides along the axial direction of the central shaft 3. Correspondingly, the end of the central shaft 3 close to the vertical plate 8 is fixedly installed with a protrusion 401 which abuts against the vertical plate 8. The vertical plate 8 is provided with a slope 801 at the position corresponding to the protrusion 401, and the protrusion 401 and the slope 801 are both designed in a side V shape. When the vertical plate 8 rises or falls, the protrusion 401 and the slope 801 can drive the hanging rod 4 to move away from the central shaft 3 and stretch the second spring.

[0052] In order to realize the up and down movement of the vertical plate 8, the surface of the vertical plate 8 away from the hanging rod 4 is fixedly installed with a partition plate 605 which is fixedly connected with the guide rod 602. When the guide rod 602 moves relative to the central shaft 3, the partition plate 605 can drive the vertical plate 8 to rise and fall correspondingly. Correspondingly, the inside of the central shaft 3 is provided with a bottom groove 303 for arranging the guide rod 602 and the first spring 603. The inside of the central shaft 3 is provided with a sliding groove 304 which is connected with the bottom groove 303 and the cavity 305, and the sliding groove 304 is used for arranging the partition plate 605.

[0053] Further, the sliding groove 304 has a certain length along the radial direction of the central shaft 3, so that when the guide rod 602 rises and falls relative to the central shaft 3, the partition plate 605 has a certain rising and falling space in the sliding groove 304. In addition, the sliding groove 304 also has a certain length along the circumferential direction of the central shaft 3, so that when the central shaft 3 rotates, the partition plate 605 also has a certain avoiding space in the sliding groove 304.

[0054] In use, the workpiece can be lowered into the machining groove 2 and rotated by the telescopic rod 601, the central shaft 3, the retainer 504 and the like, and the workpiece can be moved horizontally in the machining groove 2 to rotate the central shaft 3 and the workpiece again by the telescopic rod 601, the central shaft 3 and the arc block 7 and the like, thereby further improving the electroplating effect on the workpiece. The working process and effect are the same as those of the first embodiment, and will not be repeated here. The difference lies in that when the central shaft 3 is lifted or lowered relative to the guide rod 602, the guide rod 602 drives the vertical plate 8 to lift or lower in the cavity 305 through the partition plate 605, the vertical plate 8 drives the hanging rod 4 to move away from the central shaft 3 and stretch the second spring through the protrusion 401, and at this time the hanging rod 4 drives the workpiece to move correspondingly along the radial direction of the central shaft 3; when the vertical plate 8 is reset, the second spring can automatically reset the hanging rod 4 along the central shaft 3.

[0055] Compared with the second embodiment, when the central shaft 3 is lifted or lowered relative to the guide rod 602, the hanging rod 4 and the workpiece can be reciprocally moved along the radial direction of the central shaft 3 by the cooperation of the guide rod 602, the partition plate 605, the vertical plate 8 and the protrusion 401 and the like, the reciprocating movement in the machining groove 2 can further improve the electroplating effect on the workpiece, and the reciprocating movement after resetting can further avoid the residual machining liquid. The overall design is combined with the movement of the guide rod 602, does not affect the self-rotation of the hanging rod 4 and the workpiece driven by the central shaft 3, and has the functions of improving the electroplating effect and removing the machining liquid, is more functional, and meets more requirements in actual use.
