[0003] Most transmission riveting assembly equipment uses a vibrating plate to automatically transfer silver contacts. However, the positions of the silver contacts and the base cannot correspond precisely, requiring manual operation. In addition, the base must be placed by hand, which is inefficient and has unstable quality. The assembled base is placed on one side of the workbench and needs to be sorted later, which brings great inconvenience to production. Summary of the Invention

[0006] Preferably, a second hydraulic cylinder is provided on one side of the support seat, and a support block is provided at the telescopic end of the second hydraulic cylinder. The upper end surface of the support block is connected to a locking rod through the telescopic end of the second cylinder. A negative pressure device is clamped inside one end of the locking rod, and a card shell is installed at one end of the negative pressure device. A groove for adapting contact adsorption is provided inside the card shell.

[0007] Preferably, the positioning and feeding mechanism includes a circular table fixedly arranged on the upper end surface of the operating table, a pad is provided on the upper end surface of the circular table near the middle, and rotating pressing components are provided on both sides of the upper end surface of the pad.

[0008] Preferably, the rotating pressure component includes a T-shaped rod fixedly arranged, and mounting columns are vertically installed on the upper surfaces of both ends of the T-shaped rod, a rotating shaft is inserted above the inside of the mounting column, and an L-shaped frame is rotatably mounted on the outside of the rotating shaft, a pressure block is provided on the inner surface of the L-shaped frame, and a ball is provided on the inner surface of the L-shaped frame and on one side close to the pressure block.

[0009] Preferably, a positioning column is provided on the upper end surface of the circular table and near the two T-shaped rods, the upper part of the interior of the positioning column is hollow, and an annular coil is provided on the outside of the positioning column, and a plurality of air jets are installed on the upper part of the interior of the annular coil, an air pump is provided on the upper end surface of the circular table and away from the two T-shaped rods, and air nozzles are installed on the upper and lower parts of the air pump, a roller rack is inserted into the front end of the interior of the circular table, a material unloading rack is provided on the outer wall of the front end of the operating table and near the bottom of the roller rack, and a controller is provided on the upper end surface of one side of the workbench.

[0010] Preferably, the delivery mechanism includes a guide frame fixedly arranged on the upper end surface of the base and away from the side of the operating table, a first hydraulic cylinder is arranged at the lower outside of the guide frame, a horizontally placed clamping rod is arranged at the telescopic end of the first hydraulic cylinder, the clamping rod slides with the guide frame, a first cylinder is arranged on the lower end surface of one side of the clamping rod, a mounting block is arranged at one end of the first cylinder, and a pneumatic clamp is arranged on the outer wall of the mounting block.

[0011] Preferably, a stand is provided on the upper end surface of the base and near the clamping rod, a loading rack is provided on the upper end surface of the stand, a feeding channel for placing the base is opened above the inside of the loading rack, and the pneumatic clamp is located above one end of the loading rack.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The vibrating loading tray can automatically arrange and transport the silver contacts. The silver contacts reach the material guiding mechanism through the unloading channel and the transfer rack. In the material guiding mechanism, the third cylinder pushes the slide rod to push the silver contacts to the jamming point. The adsorption effect of the air jet and the negative pressure device is used to accurately transfer the silver contacts to the preset holes above the base. The entire process does not require human intervention, which improves the loading efficiency and positioning accuracy.

[0014] By setting a loading rack in conjunction with the first cylinder, the pneumatic clamp on the outside of the front mounting block can be driven to move horizontally, the base placed above the loading rack is clamped, and then transported to the two sets of T-shaped rods at the round table. When the pneumatic clamp releases the base, the lower end surface of the base will be in contact with the lower end ball of the L-shaped rack. When the base with a certain weight is clamped and installed, the L-shaped rack sinks downward according to the weight, and the pressing block just presses against the two side walls of the base to clamp the base, so that the preset hole on the inner surface of the base falls accurately to the outside of the positioning column, and the lower end surface of the base is fixed. Fitting with the upper surface of the annular coil, when the silver contact is riveted, the annular coil is transported by the external inflatable equipment, and air is blown at the lower end of the annular coil, causing the base to rise upward. After the base leaves the L-shaped frame, the L-shaped frame automatically moves downward to one end of the mounting column according to the weight of the pressure block. At this time, the air pump blows toward the base and blows the base toward the roller frame. With the guidance of the airflow, the riveted base moves toward the lower material rack. A box can be set at the lower end of the lower material rack to hold it, thereby reducing the steps of subsequent workbench sorting. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] like Figures 1-9 The silver contact assembly riveting equipment shown includes a workbench 1, a vibrating loading tray 3 and a riveting main unit 4. A base 12 is provided on the upper end surface of the workbench 1, and a bracket is provided on one side of the base 12. The outside of the bracket is connected to the riveting main unit 4 through a lifting device 2. The vibrating loading tray 3 is located on the upper end surface of the workbench 1 and close to the side of the base 12. A unloading channel 23 is provided at one end of the vibrating loading tray 3, and a transfer rack 15 is provided at the front end of the unloading channel 23. A material guiding mechanism is provided on one side of the transfer rack 15. An operating table 8 is provided on the upper end surface of the base 12, and a positioning and feeding mechanism is provided on the upper end surface of the operating table 8. A delivery mechanism is provided on the upper end surface of the base 12 and close to the side of the operating table 8.

[0028] The material guiding mechanism includes a machine base 24 and a support base 25 respectively fixed on one side of the upper end surface of the operating table 8. One end of the inside of the machine base 24 is connected to a slide rod 39 through the third cylinder 18. A card slot 37 is provided on the upper end surface of the slide rod 39. A baffle 38 is provided on the side of the transfer rack 15 away from the unloading channel 23. A connecting groove is provided on the upper end surface of the machine base 24 and close to the transfer rack 15. One end of the connecting groove is connected to the card slot 37, and one end of the baffle 38 covers the top of the connecting groove. The purpose is to avoid the silver contact from bulging when it slides to the connecting groove, limit it, and ensure the neat and orderly movement of the silver contact.

[0029] A second hydraulic cylinder 22 is provided on one side of the support base 25. A support block 41 is provided at the telescopic end of the second hydraulic cylinder 22. The upper end surface of the support block 41 is connected to the locking rod 14 through the telescopic end of the second cylinder 7. A negative pressure device 40 is clamped inside one end of the locking rod 14. A card housing 36 is installed at one end of the negative pressure device 40. A groove adapted for contact adsorption is provided inside the card housing 36.

[0030] After the vibrating loading tray 3 is started, the silver contacts are automatically arranged and then transferred to the transfer rack 15 through the unloading channel 23. The silver contacts move forward in an orderly manner and slide through the connecting groove into the inner groove 37 of the slide rod 39. The third cylinder 18 pushes the slide rod 39 to the front end of the negative pressure device 40. The negative pressure device 40 attracts the silver contacts to the card shell 36 and pushes them to the top of the base through the second cylinder 7.

[0031] It should be noted that the groove inside the card shell 36 abuts against the outer edge of one side of the silver contact. When the negative pressure device 40 does not produce an adsorption effect, the silver contact can slide down from this position by itself without hindering the loading of the silver contact.

[0032] The positioning and feeding mechanism includes a round table 16 fixedly arranged on the upper end face of the operating table 8, and a pad 27 is arranged on the upper end face of the round table 16 near the middle. Rotating pressing components are arranged on both sides of the upper end face of the pad 27. The round table 16 corresponds to the riveting main machine 4, and the corresponding rotating pressing component is arranged at the lower end of the riveting main machine 4.

[0033] The rotating pressing assembly includes a T-shaped rod 29 fixedly mounted thereon. Mounting posts 34 are vertically mounted on the upper surfaces of both ends of the T-shaped rod 29. A rotating shaft 35 extends through the interior of the mounting posts 34. An L-shaped frame 32 is rotatably mounted on the exterior of the rotating shaft 35. A pressing block 31 is mounted on the inner surface of the L-shaped frame 32. A ball bearing 33 is mounted on the inner surface of the L-shaped frame 32, adjacent to the pressing block 31.

[0034] Because the L-shaped frame 32 itself is rotatably connected to the mounting post 34 via the rotating shaft 35, the pressing block 31 at the upper end and the protruding portion of the L-shaped frame 32 itself will press down on the pressing block 31 due to the weight when the L-shaped frame 32 cannot make contact. When the base is pressed down to the lower end of the L-shaped frame 32, the base sinks with the L-shaped frame 32, causing the pressing block 31 on the inner surface of the L-shaped frame 32 to press against the outer side of the base, thereby automatically completing the positioning of the base and allowing the preset hole on the inner surface of the base to accurately abut against the positioning post.

[0035] A positioning column is provided on the upper end surface of the truncated table 16 and near the two T-shaped rods 29. The upper part of the interior of the positioning column is hollowed out, and an annular coil 30 is provided on the outside of the positioning column. A plurality of air jets 28 are installed in the upper part of the annular coil 30. An air pump 26 is provided on the upper end surface of the truncated table 16 and away from the two T-shaped rods 29. Air nozzles are installed in the upper and lower parts of the air pump 26. A roller frame 17 is inserted into the front end of the truncated table 16. A material unloading frame 9 is provided on the outer wall of the front end of the operating table 8 and near the bottom of the roller frame 17. A controller 10 is provided on the upper end surface of one side of the workbench 1.

[0036] The upper part of the positioning column is hollowed out to facilitate the positioning of the silver contact, so that the lower end of the silver contact can accurately fit into the preset hole of the base. Later, when riveting, it can press against the silver contact to allow the silver contact to be riveted to the base.

[0037] The annular coil 30 is connected to the external inflation device, which can blow the base at the lower end so that the base can rise and be ejected. Due to the ball 33 of the L-shaped frame 32, the base can move up smoothly. When there is no base pressing, the L-shaped frame 32 rotates to the side of the pressing block 31. At this time, the base is pushed upward, and the air pump 26 blows the base through the air nozzle, so that the base falls to the roller frame 17. Finally, the base after riveting is automatically guided to fall to one end through the unloading frame 9;

[0038] The controller 10 can control each driving element.

[0039] The delivery mechanism includes a guide frame 11 fixedly mounted on the upper end surface of the base 12 and away from the side of the operating table 8. A first hydraulic cylinder 21 is provided on the lower portion of the guide frame 11. A horizontally placed clamping rod 5 is provided at the telescopic end of the first hydraulic cylinder 21. The clamping rod 5 slides with the guide frame 11. A first pneumatic cylinder 6 is provided on the lower end surface of one side of the clamping rod 5. A mounting block is provided at one end of the first cylinder 6. A pneumatic clamp 19 is provided on the outer wall of the mounting block.

[0040] The first hydraulic cylinder 21 can drive the clamping rod 5 to slide flexibly, so that the pneumatic clamp 19 can move up and down, which is convenient for clamping the base and subsequent material discharge. The first cylinder 6 can drive the front mounting block to move horizontally, so that the pneumatic clamp 19 can move the clamped base to the side of the table 16.

[0041] A stand 13 is provided on the upper end surface of the base 12 and near the clamping rod 5. A loading rack 20 is provided on the upper end surface of the rack 13. A feeding channel for placing the base is opened above the upper part of the loading rack 20. A pneumatic clamp 19 is located above one end of the loading rack 20.

[0042] The stand 13 is used to support the loading rack 20. The feeding channel provided inside the loading rack 20 is convenient for placing multiple groups of bases, so that the pneumatic clamp 19 can clamp the bases in turn and move the loading.

[0043] Working principle: when in use, the base must be placed first, and the front mounting block and the pneumatic clamp 19 are driven by the first cylinder 6 to move to the loading rack 20. The first hydraulic cylinder 21 controls the pneumatic clamp 19 to clamp the base by lifting. After clamping, the first cylinder 6 is transported to the upper side of the round table 16 to control the base to move down to the middle of the four groups of L-shaped frames 32. When the pneumatic clamp 19 releases the limit on the base, the base fits with the ball bearings 33 on the inner surface of the lower end of the L-shaped frame 32. The rolling fit of the ball bearings 33 allows the base to sink to the lower end of the four groups of L-shaped frames 32. As the base sinks, the weight of the lower end of the L-shaped frame 32 increases, causing the L-shaped frame 32 to tilt and press down to the lower end, and the corresponding pressing block 31 on the upper inner surface is against the inner surface of the base. When the base is stably clamped, the silver contacts need to be transported.

[0044] After the vibrating loading tray 3 is started, the silver contacts are arranged and then transferred to the transfer rack 15 through the unloading channel 23. The silver contacts move forward in an orderly manner. The silver contacts located at one end of the transfer rack 15 slide into the card slot 37 at the slide rod 39 through the connecting groove. The third cylinder 18 pushes the slide rod 39 to the front end of the negative pressure device 40. The negative pressure device 40 adsorbs the silver contacts to the card shell 36 and pushes them to the top of the base through the second cylinder 7. Under the lifting and lowering adjustment of the second hydraulic cylinder 22, the silver contacts fall toward the hollow of the positioning column. When the position of the silver contacts is determined, the lifting device 2 drives the riveting host 4 to move downward and hammer the upper edge of the silver contacts, causing the silver contacts to be riveted to the base.

[0045] After riveting is completed, the annular coil 30 blows air to make the base rise and leave the L-shaped frame 32. The L-shaped frame 32 moves downward due to its own weight. The air pump 26 blows the base to make it fall to the roller frame 17, and finally the blanking is collected by the blanking frame 9.

[0046] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the invention as claimed.
