Subsequently, the movement of the transfer seat will not cause the individual terminal blocks to have edge deformation.

Description

Technical Field

[0001] The present invention relates to the technical field of loading machines, and particularly relates to a fully automatic feeding and sorting machine for terminal blocks. Background Art

[0002] A terminal block is an electrical component used for safely connecting wires, and realizes reliable conduction between the wires and equipment or circuits through mechanical fixation or elastic pressure. In actual use, some wires have terminal blocks with pre-connected numbers at their ends. In large-scale automated production of such wires, the preparation workshop of the manufacturer needs a fully automatic terminal feeder to assist in processing. Existing automatic loading machines for terminal blocks can basically meet the daily use requirements, but there are still some deficiencies that need to be improved.

[0003] Patent document CN209701579U discloses a fully automatic feeding and sorting machine for terminal blocks on the publication date of February 25, 2025. The fully automatic feeding and sorting machine for terminal blocks is composed of an automatic feeding component and an automatic sorting component, and the automatic sorting component is placed beside the automatic feeding component. The terminal blocks in the plastic bag are poured into the vibrating tray of the automatic feeding component, and then the automatic feeding component is started to automatically convey the terminal blocks out in sequence. Then, the automatic sorting component is started to separate the frontmost terminal block from the subsequent terminal blocks. The entire feeding and sorting process of the terminal blocks is not only fully automatic, but also fast and efficient, and is very suitable for the preparation workshop of electrical product manufacturers.

[0004] In the prior art such as the above patent, the sorting of terminal blocks needs to be realized through a movable transfer mechanism. The transfer mechanism usually includes a receiving groove that can individually carry terminal blocks. When transferring, the receiving groove is docked with the terminal block conveying route, and the terminal blocks are pushed in rows and squeezed into the receiving groove. At this time, whether the receiving groove is too large or too small compared to the terminal blocks, it may cause deformation of the edges of the terminal blocks or jamming of the mechanism during the subsequent movement of the transfer mechanism. Therefore, there is an urgent need for a fully automatic feeding and sorting machine for terminal blocks to solve the above problems. Summary of the Invention

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present disclosure.

[0034] Please refer to Figures 1-9 , a fully automatic feeding and sorting machine for wiring terminals provided by an embodiment of the present invention includes a feeding table 1 and a sorting table 2. The wiring terminals are continuously conveyed from the feeding table 1 to the sorting table 2. It further includes: a preparation seat 3, which is fixedly arranged on the sorting table 2 and is provided with a preparation groove 4 for accommodating the wiring terminals; a transfer seat 5, which is movably arranged on the sorting table 2 and is provided with a transfer groove 6 for completely receiving the wiring terminals. Both ends of its moving stroke have a first position where the transfer groove 6 is connected to the feeding table 1 and a second position where the transfer groove 6 is connected to the preparation groove 4; a separation component, which is used to drive the wiring terminal closest to the transfer seat 5 on the feeding table 1 away from the transfer groove 6 before the transfer seat 5 switches from the first position to the second position each time.

[0035] Specifically, the terminal includes a ring plate portion and a ring sleeve portion; at one end of the loading table 1 away from the material separating table 2, a vibrating disk is connected. The vibrating disk can automatically guide the terminals into the required state and continuously convey them onto the loading table 1 for conveyance. This is prior art and will not be elaborated here. The loading table 1 is set as a parallel plate body with a gap in the middle. Each terminal has its ring plate portion embedded in the gap on the loading table 1, and the ring sleeve portion is supported on the parallel plate body and slides and conveys on the loading table 1 with the convex direction facing the same side. The material separating table 2 is arranged at the end of the loading table 1 in the conveying direction of the terminals. The preparation seat 3 is arranged at an interval from the conveying end of the loading table 1; the preparation groove 4 is arranged parallel to the conveying direction of the loading table 1 and is offset; the transfer seat 5 is arranged between the loading table 1 and the preparation seat 3; the side of the transfer groove 6 away from the loading table 1 is blocked by the outer wall of the preparation seat 3. Only when the transfer groove 6 corresponds to the preparation groove 4, the side of the transfer groove 6 away from the loading table 1 communicates with the preparation groove 4. The transfer groove 6 is arranged parallel to the conveying direction of the loading table 1, and the dimension of the transfer groove 6 in this direction is larger than the maximum dimension of the ring plate portion of the terminal in the corresponding direction, including the maximum value within the dimension error range of the terminal. Thus, any terminal can completely enter the transfer groove 6, and another adjacent terminal on the loading table 1 is in a way that one edge is at the connection and transition position between the loading table 1 and the transfer groove 6. The conveying end of the loading table 1 is always blocked by the transfer seat 5, and only when the transfer groove 6 corresponds to the conveying end of the loading table 1, the conveying end of the loading table 1 communicates with the transfer groove 6. The separating component drives the terminal on the loading table 1 closest to the transfer seat 5 away from the transfer groove 6, that is, to ensure that the edge of this terminal will not be at the connection and transition position between the loading table 1 and the transfer groove 6. In the actual use of this technical solution, when the transfer seat 5 is connected to the loading table 1 at the first position, the terminals closely arranged in a row on the loading table 1 smoothly squeeze the foremost terminal into the transfer groove 6. Then, before the transfer seat 5 is ready to move to the second position, the separating component drives the terminal on the loading table 1 closest to the transfer seat 5 away from the transfer groove 6, that is, the edge of this terminal will not be at the transition position between the loading table 1 and the transfer groove 6. Subsequently, the transfer seat 5 moves from the first position to the second position, and during the movement, no individual terminal will have its edge deformed. The transfer seat 5 also moves the terminal in the transfer groove 6 to the corresponding preparation groove 4 on the preparation seat 3.

[0036] Compared with the prior art, a fully automatic feeding and sorting machine for terminal blocks proposed in an embodiment of the present invention is provided with a transfer groove 6 that can completely receive the terminal blocks. When the transfer seat 5 is connected to the feeding table 1 at the first position, the terminal blocks tightly conveyed in a row on the feeding table 1 smoothly squeeze the terminal block at the very head into the transfer groove 6. Then, before the transfer seat 5 is ready to move to the second position, the separating component drives the terminal block closest to the transfer seat 5 on the feeding table 1 away from the transfer groove 6, that is, the edge of the terminal block will not be at the transition position between the feeding table 1 and the transfer groove 6. Subsequently, the movement of the transfer seat 5 will not cause individual terminal blocks to have deformed edges.

[0037] As a preferred technical solution of this embodiment, a guide rail 7 is fixedly arranged on the sorting table 2 between the feeding table 1 and the preparation seat 3. The lower end of the transfer seat 5 is movably connected to the guide rail 7. Specifically, the arrangement of the guide rail 7 ensures the stable movement direction of the transfer seat 5, specifically: the transfer seat 5 moves horizontally and perpendicularly to the conveying direction of the feeding table 1; one end of the guide rail 7 is provided with a limit to ensure that the transfer seat 5 stops at the first position.

[0038] As a preferred technical solution of this embodiment, the separating component includes a first bracket 8 fixedly arranged on the sorting table 2. A push block 9 is movably arranged at the upper end of the first bracket 8. One end of the push block 9 extends out of the first bracket 8 and is suspended above the feeding table 1 at a height corresponding to the upper end of the terminal block. The side of the extended end of the push block 9 away from the transfer seat 5 is set as an inclined surface. A push rod 10 is arranged in the first bracket 8 in a lifting and moving manner. The upper end of the push rod 10 is movably connected to the push block 9 through a connecting rod 11. A driving component for driving the push rod 10 to move is arranged on the sorting table 2. Specifically, the first bracket 8 is arranged on the side of the conveying end of the feeding table 1; the push block 9 corresponds to the sleeve part of the terminal block at the conveying end of the feeding table 1; the moving direction of the push block 9 is set perpendicular to the conveying direction of the feeding table 1; when the inclined surface of the push block 9 approaches and squeezes the sleeve part of the corresponding terminal block, the squeezed terminal block moves in the direction away from the transfer seat 5 due to the guidance of the inclined surface; both ends of the connecting rod 11 are hinged to the end of the push block 9 away from the terminal block and the upper end of the push rod 10 respectively; the upper end of the connecting rod 11 is inclined at a certain angle towards the push block 9; when the push rod 10 rises, the push block 9 is pushed close to the terminal block through the connecting rod 11, and when the push rod 10 descends, the push block 9 is pulled away from the terminal block through the connecting rod 11; the driving component makes the push block 9 move by driving the push rod 10 to lift and lower.

[0039] As a further preferred technical solution of this embodiment, the driving component includes a hydraulic cylinder 12 fixedly installed on the material distribution table 2. A collar 13 is synchronously moved at the output end of the hydraulic cylinder 12. A push rod 14 is movably arranged in the first support 8. One end of the push rod 14 is in wedge-shaped cooperation with the lower end of the ejector rod 10. The side wall of the push rod 14 is fixedly connected to the collar 13. Specifically, the hydraulic cylinder 12 is arranged in the moving direction of the transfer seat 5, and the telescopic direction of the output end of the hydraulic cylinder 12 is parallel to the moving direction of the transfer seat 5. The hydraulic cylinder 12 is also arranged on the same side of the feeding table 1 as the first support 8. The collar 13 moves axially synchronously with the output end of the hydraulic cylinder 12. The push rod 14 moves horizontally and the moving direction is consistent with the extending direction and is the same as the moving direction of the output end of the hydraulic cylinder 12. The push rod 14 is T-shaped, and the end deviating from the moving direction is the side branch end and is fixedly connected to the collar 13. One end of the push rod 14 close to the feeding table 1 is set as a shovel shape and is in wedge-shaped cooperation with the lower end of the ejector rod 10. In actual use of this technical solution, when the transfer seat 5 is in the first position, a terminal is completely received in the transfer groove 6. The hydraulic cylinder 12 is started to extend the output end, that is, it drives the collar 13 to move in the direction close to the feeding table 1. The collar 13 drives the push rod 14 to move. The push rod 14 wedges and presses the lower end of the ejector rod 10 with its end, so that the ejector rod 10 first rises and then maintains the height. Then, the push block 9 is linked through the connecting rod 11 to move close to and press its corresponding terminal and then maintain the position. Then, the pressed terminal moves away from the transfer groove 6, so that there is no terminal at the connection and transition part between the feeding table 1 and the transfer groove 6. Then, the transfer seat 5 only makes a switching movement from the first position to the second position, avoiding the terminals with edge deformation generated during the material distribution and transfer process. Finally, when the transfer seat 5 returns from the second position to the first position, the hydraulic cylinder 12 also contracts the output end. Then, the push rod 14 is driven back by the collar 13. After the end of the push rod 14 is separated from the lower end of the ejector rod 10, the descent of the ejector rod 10 is not restricted. Then, the terminals tightly conveyed on the feeding table 1 can automatically push open the push block 9, so that a new terminal is completely fed into the transfer groove 6, and thus the cycle is successfully completed.

[0040] In another embodiment proposed by the present invention, a sleeve 15 that moves synchronously is sleeved on the output end of the hydraulic cylinder 12. A first docking plate 16 is provided at the end of the sleeve 15. A second docking plate 17 that matches the first docking plate 16 is provided on the transfer seat 5. A magnetic attraction groove 18 is provided on the first docking plate 16, and a protruding magnetic attraction piece 19 is provided on the second docking plate 17. Specifically, the sleeve 15 can move axially synchronously with the output end of the hydraulic cylinder 12; a collar 13 is sleeved outside the sleeve 15, and a convex ring is provided on the sleeve 15 to limit the collar 13, so that the collar 13 moves axially synchronously with the sleeve 15; when the output end of the hydraulic cylinder 12 contracts to the limit position, it drives the position where the first docking plate 16 is located, and the position where the transfer seat 5 drives the second docking plate 17 when it is in the first position. There is a gap between the first docking plate 16 and the second docking plate 17 at the above positions. During the process of the hydraulic cylinder 12 shrinking the above gap between the first docking plate 16 and the second docking plate 17 by extending the output end, the end of the push rod 14 just has a wedge-shaped extrusion effect on the ejector rod 10. When the ejector rod 10 is pushed by the extrusion to rise to the highest position, the first docking plate 16 and the second docking plate 17 just fit together. Subsequently, when the output end of the hydraulic cylinder 12 continues to extend, it can push the transfer seat 5 to move; multiple magnetic attraction grooves 18 can be provided, which are evenly arranged circumferentially around the axis of the sleeve 15. At this time, the magnetic attraction pieces 19 correspond to the magnetic attraction grooves 18 one by one. When the first docking plate 16 and the second docking plate 17 fit together, the magnetic attraction pieces 19 just embed into the magnetic attraction grooves 18 and are magnetically fixed. The first docking plate 16 and the second docking plate 17 no longer rotate relative to each other, and the first docking plate 16 can push and pull the second docking plate 17 to move; in addition, the magnetic attraction groove 18 and the magnetic attraction piece 19 can also be preferably a single polygonal structure; in the actual use after the first docking plate 16 and the second docking plate 17 are magnetically fixed, when the transfer seat 5 can move from the first position to the second position, the first docking plate 16 can push the second docking plate 17 to move, and when the transfer seat 5 can move from the second position to the first position, the first docking plate 16 can pull the second docking plate 17 to move. That is, in the above cases, the output end of the hydraulic cylinder 12 can drive the transfer seat 5 to move synchronously.

[0041] In yet another embodiment proposed by the present invention, a second bracket 20 is fixedly provided on the material distribution table 2. A swing rod 21 is hinged on the second bracket 20. A linkage assembly for driving the swing rod 21 to swing is provided on the material distribution table 2. When the transfer seat 5 is in the second position, the linkage assembly drives the lower end of the swing rod 21 to swing into the transfer groove 6 and push the terminal in the transfer groove 6 into the preparation groove 4. Specifically, the second bracket 20 and the first bracket 8 are arranged on two opposite sides of the loading table 1; the swing plane of the swing rod 21 is correspondingly arranged with the preparation groove 4; when the transfer seat 5 is in the second position, the swing plane of the swing rod 21 also corresponds to the transfer groove 6; when the linkage assembly drives the swing rod 21 to swing upward, that is, the lower end of the swing rod 21 enters the transfer groove 6, and when the linkage assembly drives the swing rod 21 to swing downward, that is, the lower end of the swing rod 21 leaves the transfer groove 6.

[0042] As a preferred technical solution of this embodiment, the linkage assembly includes a third bracket 22 fixedly arranged on the material distribution table 2. A linkage rod 23 is movably arranged on the third bracket 22. A sliding groove 24 is arranged at the upper end of the linkage rod 23. A sliding rod 25 fixedly connected with the sliding groove 24 in a movable manner is arranged on the swing rod 21. When the transfer seat 5 is in the second position, the linkage rod 23 is linked with the second docking plate 17. Specifically, the third bracket 22 and the hydraulic cylinder 12 are arranged on opposite sides of the preparation seat 3; the moving direction of the linkage rod 23 is parallel to the conveying direction of the loading table 1; the linkage rod 23 is arranged vertically, and the sliding groove 24 is also arranged vertically. The sliding rod 25 performs a lifting movement in the sliding groove 24; and the sliding rod 25 performs an arc-shaped movement along with the swing of the swing rod 21. Thus, the horizontal component movement of the sliding rod 25 corresponds to the horizontal movement of the linkage rod 23. When the linkage rod 23 moves along the conveying direction of the loading table 1, the swing rod 21 is driven to swing upward through the sliding groove 24 and the sliding rod 25. When the linkage rod 23 moves against the conveying direction of the loading table 1, the swing rod 21 is driven to swing downward through the sliding groove 24 and the sliding rod 25; the linkage between the linkage rod 23 and the second docking plate 17 occurs after the transfer seat 5 moves to the second position and stops; the second docking plate 17 is rotatably arranged on the transfer seat 5.

[0043] As a preferred technical solution of this embodiment, a rotating shaft 26 is rotatably arranged in the transfer seat 5. One end of the rotating shaft 26 is fixedly connected with the second docking plate 17 coaxially, and the other end is fixedly connected with a gear 27 coaxially. A rack 28 matched with the gear 27 is fixedly arranged at the lower end of the linkage rod 23. When the transfer seat 5 is in the second position, the gear 27 and the rack 28 remain meshed. A spiral groove 29 is arranged on the inner wall of the sleeve 15. A sliding projection 30 slidably connected with the spiral groove 29 is arranged on the output end of the hydraulic cylinder 12. Specifically, the axial direction of the rotating shaft 26 is coaxially arranged with the axial direction of the sleeve 15; when the transfer seat 5 is in the second position, the output end of the hydraulic cylinder 12 can still continue to extend for a certain distance. At this time, the transfer seat 5 no longer moves, and the sleeve 15 no longer moves under the condition that the first docking plate 16 and the second docking plate 17 are in contact. Thus, relative movement occurs between the output end of the hydraulic cylinder 12 and the sleeve 15, and then the spiral transmission between the spiral groove 29 and the sliding projection 30 is triggered, that is, the sleeve 15 rotates; a guiding strip 39 is fixedly arranged on the side wall of the rack 28 close to the third bracket 22. A guiding groove 40 matched with the guiding strip 39 is arranged in the third bracket 22. An elastic member 41 that hinders the guiding strip 39 from moving along the conveying direction of the loading table 1 is arranged in the guiding groove 40.

[0044] In actual use of the above embodiments, when the transfer seat 5 is pushed by the sleeve 15 and moves towards the second position, it drives the gear 27 to move towards the position meshing with the rack 28; when the transfer seat 5 reaches the second position, the gear 27 meshes with the rack 28 and remains engaged. At this time, the transfer seat 5 can no longer move, and with the first docking plate 16 and the second docking plate 17 in contact, the sleeve 15 also stops moving. Then, the continuous elongation of the output end of the hydraulic cylinder 12 causes relative sliding between the spiral groove 29 and the sliding protrusion 30, making the sleeve 15 rotate. The sleeve 15 drives the rotating shaft 26 to rotate through the magnetic attraction and fixation of the first docking plate 16 and the second docking plate 17. The rotating shaft 26 then drives the gear 27 to rotate, and the gear 27 drives the rack 28 to move the linkage rod 23. Among them, the elastic member 41 is compressed under extrusion and stores elastic potential energy. At this time, the linkage rod 23 moves along the conveying direction of the loading table 1, so that the swing rod 21 swings upward into the transfer groove 6 to push the terminal in the transfer groove 6 into the preparation groove 4; then, when the output end of the hydraulic cylinder 12 starts to contract, it will first release the elastic potential energy of the elastic member 41, causing the rack 28 to move back. On the one hand, the rack 28 drives the linkage rod 23 to move back, causing the swing rod 21 to swing downward and disengage from the transfer groove 6. On the other hand, the rack 28 meshes and drives the gear 27, causing the rotating shaft 26 to rotate back. Then, with the first docking plate 16 and the second docking plate 17 magnetically fixed, the sleeve 15 rotates. After the elastic potential energy of the elastic member 41 is released, the continuous contraction of the output end of the hydraulic cylinder 12 can drive the sleeve 15, and the sleeve 15 then pulls the transfer seat 5 back through the magnetically attracted first docking plate 16 and second docking plate 17. The transfer seat 5 switches to the first position. When the transfer seat 5 moves to the first position, the transfer seat 5 can no longer be driven by the hydraulic cylinder 12. Then, the output end of the hydraulic cylinder 12 pulls the sleeve 15 to cancel the magnetic attraction and separation between the first docking plate 16 and the second docking plate 17. At the same time, the output end of the hydraulic cylinder 12 drives the push rod 14 to move back through the sleeve 15 and the collar 13, so that the ejector rod 10 gradually disengages from the end of the push rod 14. Then, the ejector rod 10 can freely descend, and the push block 9 can be freely moved back under the extrusion of the continuously conveyed terminals, thus realizing the cycle.

[0045] As a preferred technical solution of this embodiment, the output end of the hydraulic cylinder 12 is connected to the sleeve 15 by sleeving a first coil spring 31, and the rotating shaft 26 is connected to the transfer seat 5 by sleeving a second coil spring 32. Specifically, the setting of the first coil spring 31 limits the angular position of the sleeve 15 relative to the output end of the hydraulic cylinder 12, and the setting of the second coil spring 32 limits the angular position of the rotating shaft 26 relative to the transfer seat 5. Under the above limitations, the magnetic attraction groove 18 on the first docking plate 16 just corresponds to the magnetic attraction piece 19 on the second docking plate 17; the gear 27 also just corresponds to the rack 28.

[0046] In order to ensure that the connecting terminal is stably located in the transfer groove 6 and moves with the transfer seat 5, the inner wall width of the transfer groove 6 matches the thickness of the annular portion of the connecting terminal. As a result, when the connecting terminal enters and exits the transfer groove 6, it is easy to slide against the inner wall of the transfer groove 6, thereby possibly damaging the surface coating of the connecting terminal. In this regard, the following embodiment is proposed to solve this problem.

[0047] In another embodiment of the present invention, a plurality of spray holes 33 are provided at the lower end of the rocker arm 21, a piston rod 34 is fixedly provided on the sliding rod 25, a cavity 35 matching the piston rod 34 is provided on the linkage rod 23, a liquid tank 36 is provided on the material distribution table 2, the liquid tank 36 is connected with the cavity 35 through a liquid inlet pipe 37, and the piston rod 34 is connected with the spray hole 33 through a liquid outlet pipe 38, and both the liquid inlet pipe 37 and the liquid outlet pipe 38 are one-way flow pipes. Specifically, the cavity 35 is opened at the lower end of the sliding groove 24 to guide the moving direction of the sliding rod 25; the liquid tank 36 is filled with lubricating oil; both the liquid inlet pipe 37 and the liquid outlet pipe 38 are integrated with a one-way valve, so that the liquid inlet pipe 37 only guides the liquid in the liquid tank 36 to the cavity 35 in one direction, and the liquid outlet pipe 38 only guides the liquid in the cavity 35 to the spray hole 33 in one direction. In actual use of the present technical solution, when the linkage rod 23 is linked to move along the conveying direction of the loading platform 1, the rocker arm 21 swings upward and the lower end enters the transfer groove 6. At this time, the sliding rod 25 moves up relatively in the sliding groove 24, that is, it drives the piston rod 34 to suck in the cavity 35, so that the oil in the liquid tank 36 is introduced into the cavity 35 through the liquid inlet pipe 37; then, when the linkage rod 23 is linked to move against the conveying direction of the loading platform 1, the rocker arm 21 swings downward and gradually leaves the transfer groove 6. At this time, the sliding rod 25 moves down relatively in the sliding groove 24, that is, it drives the piston rod 34 to be compressed in the cavity 35, so that the oil in the cavity 35 is introduced into the spray hole 33 through the liquid outlet pipe 38 and sprayed out, and the oil is sprayed on the inner wall of the transfer groove 6, thereby facilitating the subsequent lubrication of the terminal block in and out of the transfer groove 6 to avoid damaging the surface coating of the terminal block.

[0048] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
