[0001] This invention relates to the field of terminal crimping technology, and more particularly to a rotary circulating automatic housing insertion machine. Background Technology

[0002] Terminal connectors are widely used plug-in components in various electronic devices, electrical equipment, and industrial control equipment. These terminal connectors mainly involve crimping wires onto metal terminals, and then assembling the metal terminals into a molded plastic connector shell. Existing equipment for processing terminals typically uses an upper die moving downwards and cooperating with a lower die to perform stamping when crimping wires to terminals. Then, a robotic arm is used to transfer the semi-finished terminal to the next workstation. Obviously, this method, which requires the robotic arm to move back and forth, is not only inefficient, but also requires multiple robotic arms to be deployed at different workstations for interactive transfer. Therefore, the inventor has proposed an improvement, namely a rotary circulating automatic plastic shell insertion machine. Summary of the Invention

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1 To be continued Figure 12 The present invention will be described in detail.

[0032] This invention discloses a rotary circulating automatic wire inserter, comprising a machine base 7, a circulating conveying device 8, a feeding mechanism 71, and at least three processing stations arranged sequentially along the circulating conveying device. The circulating conveying device is connected to multiple self-locking clamping devices for holding materials and achieving self-locking. The feeding mechanism delivers the material to the first processing station. During operation, the feeding mechanism delivers the wire to the self-locking clamping device at the processing station. After clamping, the corresponding circulating conveying process for terminal insertion is performed. Generally, the first processing station is preferably a stripping device to remove the end insulation from the wire. The entire conveying route of this equipment is efficient, completely avoiding repetitive reciprocating conveying routes and significantly improving production efficiency. Furthermore, the self-locking clamping device in this invention can completely replace the installation cost of multiple robotic arms, and the power source for the self-locking clamping device does not need to be moved, resulting in a simpler, more reliable, and more precise structure.

[0033] In addition, it should be emphasized that in this terminal plugging, the above-mentioned circulating conveying device 8 can also be set as two symmetrical sets, thereby further realizing the production and manufacturing of simultaneous plugging of dual terminals on the basis of the present invention.

[0034] As an example, the three processing stations in this equipment are equipped with at least a peeling device 72, a terminal crimping device 73, and a terminal insertion device 74. Obviously, the corresponding stations can be added or removed according to actual needs. The peeling device can directly adopt existing technology, and the existing peeling device can be installed at the corresponding station. The terminal insertion device can also directly adopt existing technology. Therefore, in this invention, the specific structure of the peeling device and the terminal insertion device will not be described in detail.

[0035] In this technical solution, the self-locking clamping device includes an assembly base 91, a first support plate 92, a second support plate 93, a clamping mechanism 94, and a linkage mechanism 95. The first support plate 92 and the second support plate 93 are symmetrically connected to the assembly base 91. The clamping mechanism 94 is movably connected between the first support plate 92 and the second support plate 93. The linkage mechanism 95 abuts against or unlocks the clamping mechanism 94. When in use, this clamping device uses the clamping mechanism 94 to clamp wires, etc., and can then be applied to a circulating production line for cyclic processing. It cannot be equipped with a power source such as a cylinder or motor for clamping and holding. When unlocking is required, external force is applied through the linkage mechanism 95. After the external force is released, the locking clamping state is automatically achieved. Its structure is simple and can be widely used in circulating production lines. It does not require the laying of air pipes or wires and is directly adapted to 360-degree circulation.

[0036] In this technical solution, the clamping mechanism 94 includes a first clamping member 941 and a second clamping member 942 that cooperates with the first clamping member 941. Both the first clamping member 941 and the second clamping member 942 are hinged between the first support plate 92 and the second support plate 93. The two clamping members cooperate with each other and interact to achieve clamping or unlocking.

[0037] In this technical solution, the first clamping member 941 is connected to a first clamp 943, and the second clamping member 942 is connected to a second clamp 944. Both the first clamp 943 and the second clamp 944 are provided with mutually cooperating teeth. This type of clamp with teeth is beneficial for clamping thin cables and wires, and has a good clamping effect.

[0038] Furthermore, the first clamping member 941 is provided with a first half gear 945, and the second clamping member 942 is provided with a second half gear 946, with the first half gear 945 and the second half gear 946 meshing with each other. This gear-type clamping has good synchronization and precise clamping. Of course, to prevent foreign objects from falling between the gears, a baffle is provided between the first support plate 92 and the second support plate 93.

[0039] In this technical solution, the linkage mechanism 95 drives either the first clamping member 941 or the second clamping member 942. Clearly, driving either clamping member can achieve the clamping effect.

[0040] In specific implementation, the lower end of the first clamping member 941 is provided with a convex hinge portion 9411, and the first support plate 92 and / or the second support plate 93 is provided with a sliding groove 921; the linkage mechanism 95 includes a first connecting rod 951, a second connecting rod 952 and a power connecting rod 953, one end of the first connecting rod 951 is hinged to the convex hinge portion 9411, one end of the second connecting rod 952 is hinged between the first support plate 92 and the second support plate 93, the other end of the first connecting rod 951 is hinged to the second connecting rod 952, the power connecting rod 953 is connected to the second connecting rod 952 in a transmission connection, and the power connecting rod 953 is connected to an unlocking pin 954, which extends through the sliding groove 921. In this embodiment, when the first link 951 and the second link 952 are at a straight angle, the current clamping is locked, and the conveying can be carried out on the production line without power source support. When unlocking is required, the power link 953 is moved downward along the slide groove 921. At this time, the straight state of the first link 951 and the second link 952 is changed to an angled state, and the first clamping member 941 and the second clamping member are separated and unlocked.

[0041] Preferably, the second link 952 and the power link 953 are an integral structure, and the second link 952 and the power link 953 form an angle. In this way, the structure is more optimized, and there is no need to hinge the second link 952 and the power link 953.

[0042] To accommodate wires of different sizes, an oblong hole 9521 is provided at the junction of the second connecting rod 952 and the power connecting rod 953. The lower end of the first connecting rod 951 is hinged to the second connecting rod 952 via a hinge shaft, which can move within the oblong hole 9521. The second connecting rod 952 is also provided with an elastic element 955 for abutting against the lower end of the first connecting rod 951. Under the action of the elastic element 955, it pushes the first connecting rod 951 to always keep the two clamping parts in a tight clamping state. When there is a larger wire, adaptive adjustment can also be achieved, that is, the hinge shaft can move within the oblong hole 9521 against the pressure of the elastic element 955.

[0043] In this technical solution, the elastic element 955 is a spring, and the second connecting rod 952 is provided with a receiving hole for placing the spring. This type of spring is easier to manufacture, process and assemble.

[0044] To facilitate unlocking, a bearing 956 is connected to the outer end of the unlocking pin 954. When the pin is moved to the corresponding work position, the bearing 956 can be pressed down by an external device to unlock the pin.

[0045] In this invention, the circulating conveying device 8 includes a circulating support plate 81 and a power mechanism 82. The circulating support plate is provided with an annular guide rail 83. The power mechanism 82 drives the self-locking clamping device to slide along the annular guide rail. Obviously, by installing multiple self-locking clamping devices on the power mechanism and forming a sliding connection with the annular guide rail, the self-locking clamping devices can be driven to perform cyclic displacement conveying under the action of the power mechanism during operation. The power mechanism itself can be a synchronous belt pulley mechanism or a sprocket conveying mechanism. Such power mechanisms belong to the prior art, and are also listed in the accompanying drawings of this invention. Therefore, their specific structure will not be described further.

[0046] As an optimized embodiment of the present invention, the terminal crimping device 73 includes a device base 1, and further includes an upper die stamping mechanism 2, a lower die stamping mechanism 3, a pushing mechanism 4, a feeding mechanism 5, and at least one set of power mechanisms 6; the power mechanism 6 drives the upper die stamping mechanism 2 to move up and down, the pushing mechanism 4 drives the lower die stamping mechanism 3 to move up and down and forms a stamping fit with the upper die stamping mechanism 2, and the feeding mechanism 5 conveys material between the upper die stamping mechanism 2 and the lower die stamping mechanism 3; during operation, when the wire flows through this crimping device, the pushing mechanism 4... Under the action of the upper die stamping mechanism 3, the lower die stamping mechanism 3 moves upward, and at the same time or afterward, the power mechanism 6 drives the upper die stamping mechanism 2 to move downward. In this way, the current wire material is kept in the natural conveying position, and the terminal crimping can be completed under the action of the upper die stamping mechanism 2 and the lower die stamping mechanism 3. Obviously, this crimping device adopts the upper die stamping mechanism 2 and the lower die stamping mechanism 3 to move in opposite directions. This can avoid the bending phenomenon caused by the upper die stamping pressing the terminal and wire downward, which is conducive to the flow of the formed terminal and wire to the next process to continue to achieve precise assembly processing.

[0047] As an optimization, the device base 1 is provided with an upper die platform 11 and a lower die platform 12. The upper die platform 11 facilitates the precise displacement of the upper die stamping mechanism 2, and the lower die platform 12 facilitates the precise displacement of the lower die stamping mechanism 3, thereby achieving the purpose of stamping connection.

[0048] In this technical solution, the upper die stamping mechanism 2 includes an upper die column 21, an upper slide table 22, and an upper die 23. The upper die table 11 is provided with a slide rail, the upper slide table 22 is slidably connected to the slide rail, and the upper die 23 is detachably connected to the upper slide table 22. The upper die column 21 is connected to the upper end of the upper slide table 22. During operation, the upper slide table 22 drives the upper die 23 to move downward along the slide rail, and with the cooperation of the lower die stamping mechanism 3, the stamping of the terminal is achieved.

[0049] For ease of assembly and connection, the upper slide 22 is provided with a connecting slot at its upper end, and the upper mold column 21 is provided with a snap-fit ​​end that mates with the connecting slot. The side of the upper slide 22 is provided with a fastening hole 221, and the connecting slot is provided with a through hole perpendicular to the fastening hole 221. The fastening hole 221 is provided with a pin 222 for tightly fitting the upper mold column 21. This pin 222 achieves abutting action with the upper mold column 21 by being inserted into the fastening hole 221. The surface of the pin 222 is polyhedral, thereby facilitating a larger contact area.

[0050] In this technical solution, the lower die stamping mechanism 3 includes a lower slide table 31, a lower die base 32, and a lower die 33. The lower die table 12 is provided with a slide rail, the lower slide table 31 is slidably connected to the slide rail, the lower die base 32 is connected to the upper end of the lower slide table 31, and the lower die 33 is detachably connected to the lower die base 32. The bottom of the lower slide table 31 is provided with a guide wheel 34, which is slidably connected to the pushing mechanism 4. During operation, the lower slide table 31 drives the lower die 33 to move upward along the slide rail, and with the cooperation of the upper die stamping mechanism 2, the stamping of the terminal is realized.

[0051] In this embodiment, the power mechanism 6 includes a servo motor 61, a reducer 62, and an eccentric mechanism 63. The reducer 62 is driven by the servo motor 61, and the eccentric mechanism 63 is driven by the reducer 62 and drives the upper die stamping mechanism 2 to move up and down. Of course, the servo motor 61 and reducer 62 can directly adopt existing technologies, so they will not be described in detail here. The eccentric mechanism 63 includes an eccentric body 631, a wheel 632, and a lifting seat 634 slidably connected to the eccentric body 631. The reducer 62 drives the wheel 632 to rotate. The wheel 632 is provided with an eccentric component 633 embedded in the eccentric body 631. The lifting seat 634 is provided with a movable groove 635 into which the eccentric component 633 extends. This eccentric mechanism 63 not only has the advantage of a compact structure during operation but also a simple structure and is easy to maintain.

[0052] In this technical solution, the pushing mechanism 4 includes a top-mounted base 41, a transverse slider 42, a longitudinal slider 43, and a driving link 44 movably connected to the longitudinal slider 43. The top-mounted base 41 is provided with a groove for accommodating the transverse slider 42, and a limit block 45 is provided above the groove. The longitudinal slider 43 is provided with a driving groove 431. The transverse slider 42 is connected to a driving pin, and the driving pin extends into the driving groove 431. The front end of the transverse slider 42 is provided with a raised arc surface for driving the lower die stamping mechanism 3. The working principle is as follows: When the driving link 44 moves, the longitudinal slider 43 moves upward. At this time, the driving groove 431 forces the transverse slider 42 to move backward. Under the action of the raised arc surface, the lower die stamping mechanism 3 is in the downward position. When the longitudinal slider 43 moves downward, the driving groove 431 forces the transverse slider 42 to move forward. Under the action of the raised arc surface, the lower die stamping mechanism 3 is in the upward position.

[0053] To simplify the structure and save costs, the drive linkage 44 is connected to the power mechanism 6. Specifically, an extension arm 64 is connected to the lifting seat 634, and the drive linkage 44 is hinged to the extension arm 64. In this way, the same power mechanism 6 can be used to simultaneously achieve the action requirements of the upper die stamping mechanism 2 and the lower die stamping mechanism 3, which can significantly reduce costs. Of course, to improve the automation and accuracy of control, a position sensor 65 can also be set next to the extension arm 64 to detect the moving position of the extension arm 64. Furthermore, the sensor 65 can be used to realize the action status of the upper die stamping mechanism 2 and the lower die stamping mechanism 3.

[0054] In this technical solution, the feeding mechanism 5 includes a conveying channel 51 and a tail material recycling bin 52. Metal terminals are typically conveyed as strips; therefore, this solution uses the conveying channel 51. For further optimization, after the terminals are stamped and assembled, this solution also includes an automatic shearing mechanism in the lower die base 32 to shear and recycle the remaining strip material after assembly. Specifically, this includes a cutter 35 and a shearing groove 321 in the lower die base 32. The cutter 35 and the shearing groove 321 form a scissor shape, and the shearing groove 321 has an inlet hole 322 for the strip material to enter and an outlet hole 323 for the remaining material after shearing to exit. The cutter 35 is preferably angled at its front end and has a trumpet-shaped shearing edge. When the lower die stamping mechanism 3 stamps upwards, the cutter 35 and the shearing groove 321 simultaneously perform a shearing action, cutting off the remaining material from the previous stamping and then allowing it to fall from the outlet hole 323 into the tail material recycling bin 52. This ingenious design eliminates the need for reconfiguration of the power drive. It should be emphasized that this solution does not limit the tool 35 to be directly hinged to the shear groove 321. The tool 35 can also be fixed on other non-moving parts. Following the above approach, the shearing action can be achieved.

[0055] Finally, it should be noted that, based on this equipment, in order to further improve its functions, the circulating conveyor can also be further equipped with a CCD detection station 75 and a soldering station. The CCD detection station 75 is equipped with a CCD detection device, while the soldering station can perform soldering on the metal parts of the wire. Obviously, more stations with different needs can be set up when the length is further increased. They will not be listed here.

[0056] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
