Description

Technical Field

[0001] The invention relates to the technical field of terminal assembly, in particular to a terminal assembly machine. Background Art

[0002] In the electronic microelectronics and automotive electronics industries, certain terminal accessories are often needed. The terminal assembly field is increasingly tending towards fully automated assembly, gradually eliminating the traditional manual assembly with high labor intensity and low production efficiency. The current terminal assembly machines have a low degree of integration and a relatively low degree of automation, and cannot achieve full-line automated production, which limits production efficiency. In addition, in order to improve the connection performance of metal wires, it is necessary to tin the wire core at the end without crimped terminals, and then rivet the tinned wires to the terminals. Existing products can only complete single-wire or double-wire tinning. There is no machine in the existing terminal assembly machines that can automatically complete the tinning of a single double-wire.

DETAILED DESCRIPTION

[0028] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0029] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0030] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0031] like Figure 1-10 As shown, a terminal assembly machine includes a frame 1, a double-wire single-root tinning device 2, a wire cutting device 3, a wire stripping device 4, a station moving device 5 and a terminal assembly device 6; the double-wire single-root tinning device 2, the wire stripping device 4, the station moving device 5 and the terminal assembly device 6 are respectively arranged on the frame 1; the wire stripping device 4 is arranged at the output end of the double-wire single-root tinning device 2; the station moving device 5 is arranged at the output end of the wire stripping device 4; the terminal assembly device 6 is arranged on one side of the station moving device 5.

[0032] Specifically, the working principle is as follows: the wire is inserted into the double-wire single tinning device 2, and then the front end of the wire is cut, stripped and twisted by the wire cutting device 3, and then the front end of the wire is tinned by the double-wire single tinning device 2, and then the wire is clamped and pulled backward by the wire rear stripping device 4 to pull the wire out a certain distance, and then the rear end of the wire is cut and stripped by the wire cutting device 3, and then the station moving device 5 clamps the cut section of wire, and moves the wire to the terminal assembly device 6, and assembles and packages the wire and the terminal; the present invention can complete the full automation of the assembly of wires and terminal blocks, with high work efficiency and low assembly cost; the double-wire single tinning device 2 has high flexibility, not only can it realize full stripping, half stripping or no stripping of two wires, it can also realize twisting and no twisting, tinning and no tinning, but also can realize the functions of tinning a single wire of the double wire, stripping a single wire and twisting a single wire.

[0033] Furthermore, the double-wire single-wire tinning device 2 includes a tinning drive mechanism 21, a threading mechanism 22, a retracting mechanism 23, a wire pressing mechanism 24 and a tinning box 25; the threading mechanism 22 is provided with two threading channels 221 that penetrate front and back; the tinning drive mechanism 21 and the tinning box 25 are respectively arranged on the frame 1; the threading mechanism 22 is arranged at the output end of the tinning drive mechanism 21; the wire pressing mechanism 24 is arranged on the threading mechanism 22; the retracting mechanism 23 includes a retracting drive member 231 and a retraction slider 232; the retraction slider 232 is provided with two retraction line channels 2321 and a wire clamping channel 2322 which penetrate front and back, the wire clamping channel 2322 is connected to one of the retraction line channels 2321 from one side of the retraction slider 232, and the wire clamping channel 2322 is perpendicular to the retraction line channel 2321; the retraction slider 232 is slidably arranged at the input end of the threading channel 221, and the retraction slider 232 is arranged at the output end of the retraction drive member 231.

[0034] Specifically, the working principle is as follows: two metal wires are respectively inserted from the two threading channels 221 and come out from the other end of the threading channel 221. The section of the metal wire that comes out is the part to be tinned. The wire retracting mechanism 23 is arranged at the input end of the threading channel 221 of the threading mechanism 22. The two metal wires come out from the threading channel 221 and ensure that the two metal wires are aligned. The wire skins on the outside of the metal wires are peeled off, and then one of the metal wires is pulled backwards by the wire retracting mechanism 23 to retract the metal wire, so that the ends of the two metal wires at the output end of the threading channel 221 are not aligned, so that one metal wire is longer and the other metal wire is shorter. At this time, the wire pressing mechanism 24 is started. The two metal wires are pressed to fix the two metal wires to prevent the metal wires from sliding in the threading channel 221, and the tinning drive mechanism 21 is started to drive the threading mechanism 22 to move, so that the two metal wires at the output end of the threading channel 221 are close to the tinning box 25, and the longer metal wire is in contact with the liquid tin in the tinning box 25, while the shorter metal wire cannot be in contact with the tinning box 25, thereby achieving the purpose of tinning a single wire; the present invention realizes the automatic retraction of the metal wire through the retracting wire mechanism 23, and then uses the tinning drive mechanism 21 to control the movement of the threading mechanism 22, so as to achieve the purpose of tinning a single metal wire, which not only has a high degree of automation, but also effectively reduces labor costs and greatly improves work efficiency;

[0035] In addition, the retraction drive member 231 is driven by a cylinder and has a fast response speed. When two metal wires pass through the threading channel 221 and one of the metal wires needs to be retracted, the retraction drive member 231 is started to move the retraction slider 232 forward by one end distance, which is the distance that the metal wire that needs to be retracted is retracted. Then, a rod or other device is used to extend from the clamping channel 2322 and press the metal wire, so that the metal wire is temporarily fixed on the retraction slider 232. At this time, the retraction drive member 231 drives the retraction slider 232 to move backward and return to its original position. At this time, the retraction slider 232 will drive the metal wire temporarily fixed on the retraction slider 232 to move backward, so that the ends of the two metal wires are in a front and back state. The present invention controls the retraction slider 232 to retract the metal wire to realize new automated retraction, which not only reduces labor costs and improves production efficiency, but also has the advantages of simple structure, low cost, and fast operation response speed.

[0036] Furthermore, the terminal assembly device 6 includes a riveting mechanism 61, a terminal clamping mechanism 62, a detection mechanism 63, a clamping mechanism 64, a heat shrink tube packaging mechanism 65 and a heating mechanism 66; the riveting mechanism 61, the detection mechanism 63, the clamping mechanism 64, the heat shrink tube packaging mechanism 65 and the heating mechanism 66 are all arranged on the frame 1; and the riveting mechanism 61, the detection mechanism 63, the clamping mechanism 64, the heat shrink tube packaging mechanism 65 and the heating mechanism 66 are arranged in sequence on one side of the workstation moving device 5; the terminal clamping mechanism 62 is arranged at the output end of the riveting mechanism 61.

[0037] Specifically, the present invention includes a riveting mechanism 61, a detection mechanism 63, a clamping mechanism 64, a heat shrink tube packaging mechanism 65 and a heating mechanism 66, a total of five stations. During the operation of the terminal assembly device 6, the metal wire is clamped by the station moving device 5, and is moved horizontally to move the metal wire above the terminal clamping mechanism 62; the terminal base is loaded from the loading machine and enters the terminal clamping mechanism 62, and the terminal base is clamped by the terminal clamping mechanism 62, and then the station moving device 5 lowers the metal wire to the riveting position of the terminal base, and the riveting mechanism 61 is started to rivet the terminal base and the metal wire, and then the terminal clamping mechanism 62 releases the terminal base, and the station moving device 5 rises to lift the riveted terminal. After completing the assembly of the terminal, the terminal is moved horizontally to the detection mechanism 63, and the riveting is detected by powering on to see if it is qualified. Then the station moving device 5 moves the terminal horizontally to the clamping mechanism 64, and clamps and fixes the riveted position of the terminal again to ensure the stability of the riveting; then the station moving device 5 moves the terminal to the heat shrink tube packaging mechanism 65 again, and after a section of heat shrink tube is sleeved on the outside of the terminal, the station moving device 5 moves the terminal to the heating mechanism 66, heats the terminal wrapped with the heat shrink tube, and makes the heat shrink tube shrink due to the heat, thereby completing the packaging of the terminal; the present application realizes the process production of fully automatic riveting, detection, clamping, packaging and heating shrinkage of the terminal, which not only improves the automation level of the production line and reduces labor costs, but also effectively improves production efficiency.

[0038] Furthermore, the wire back-stripping device 4 includes a mounting base 41, a wire clamp assembly 42 and a wire clamp translation drive assembly 43; the wire clamp translation drive assembly 43 and the back-stripping assembly are arranged on the mounting base 41; the wire clamp assembly 42 is arranged at the output end of the wire clamp translation drive assembly 43; the wire clamp assembly 42 is slidably arranged on the mounting base 41; the wire clamp translation drive assembly 43 drives the wire clamp assembly 42 to reciprocate in the horizontal direction.

[0039] Specifically, the working principle is as follows: after the wire is tinned, the wire is clamped by the wire clamp assembly 42, and then the wire clamp translation drive assembly 43 drives the wire clamp assembly 42 to pull backward, so that the wire is pulled out for a distance, and then the wire is cut by the wire cutting device 3, and the wire clamp translation drive assembly 43 drives the wire clamp assembly 42 to cooperate with the wire cutting device 3 to strip the wire, twist the wire, etc., thereby completing the automated production operation of wire cutting and stripping, and the work efficiency is high.

[0040] Furthermore, the wire clamp assembly 42 includes a wire clamp mounting seat 421, a wire clamp cylinder 422, a rear pull-up clamp 423 and a rear pull-down clamp 424; the wire clamp mounting seat 421 can be slidably arranged on the mounting base 41; the wire clamp cylinder 422 is arranged on the wire clamp mounting seat 421; the input end of the rear pull-up clamp 423 and the input end of the rear pull-down clamp 424 are respectively hingedly connected to the output end of the wire clamp cylinder 422; the middle part of the rear pull-up clamp 423 and the middle part of the rear pull-down clamp 424 are hingedly connected, and the hinge point is arranged on the wire clamp mounting seat 421, so that the rear pull-up clamp 423 and the rear pull-down clamp 424 are respectively rotatably connected to the wire clamp mounting seat 421.

[0041] Specifically, the wire is clamped by the wire clamp assembly, and then driven by the wire clamp translation drive assembly 43 to perform translational movement back and forth. After the wire is tinned, the translation drive assembly drives the wire clamp assembly 42 to approach the wire, and then starts the wire clamp cylinder 422. The wire clamp cylinder 422 drives the rear pull-up upper clamp 423 and the rear pull-down clamp 424, so that the rear pull-up upper clamp 423 and the rear pull-down clamp 424 rotate around their hinge points, so that the output end of the rear pull-up upper clamp 423 and the output end of the rear pull-down clamp 424 are close to each other, thereby clamping the wire; the wire clamp assembly 42 has a simple structure, low cost, and quick response, and can effectively clamp the wire.

[0042] Furthermore, the wire clamp translation drive assembly 43 includes a wire clamp translation drive motor 431, a wire clamp driving wheel 432, a wire clamp driven wheel 433 and a wire clamp transmission belt 434; the wire clamp translation drive motor 431 is arranged on the mounting base 41; the wire clamp driving wheel 432 and the wire clamp driven wheel 433 are respectively arranged at two ends of the mounting base 41, and the wire clamp driving wheel 432 is connected to the output end of the wire clamp translation drive motor 431; the wire clamp transmission belt 434 is arranged around the wire clamp driving wheel 432 and the wire clamp driven wheel 433, and is respectively meshed and connected with the wire clamp driving wheel 432 and the wire clamp driven wheel 433; the wire clamp assembly 42 is arranged on the wire clamp transmission belt 434.

[0043] Specifically, the wire clamp translation drive assembly 43 is driven by the translation drive motor, and the translation drive motor drives the wire clamp active wheel 432 to rotate, thereby driving the wire clamp transmission belt 434 to rotate around the wire clamp active wheel 432 and the wire clamp driven wheel 433. The wire clamp assembly 42 is arranged on the wire clamp transmission belt 434, so when the wire clamp transmission belt 434 rotates, it will drive the wire clamp assembly 42 to perform a linear translation movement. The wire clamp translation drive assembly 43 drives and transmits smoothly, so that the wire clamp assembly 42 moves smoothly.

[0044] Furthermore, the terminal assembly device 6 also includes an auxiliary clamping mechanism 10, which includes an auxiliary substrate 101, a transmission rod 102, a guide column 103, an auxiliary finger cylinder 104, an upper clamp 105 and a lower clamp 106; the guide column 103 is arranged on the frame 1, and the auxiliary substrate 101 can be slidably arranged on the guide column 103; the auxiliary finger cylinder 104 is transversely arranged on the auxiliary substrate 101; the upper clamp 105 and the lower clamp 106 are respectively arranged at the two output ends of the auxiliary finger cylinder 104, and the upper clamp 105 and the lower clamp 106 are arranged between the workstation moving device 5 and the terminal clamping mechanism 62; the two ends of the transmission rod 102 are respectively connected to the riveting mechanism 61 and the auxiliary substrate 101.

[0045] Specifically, the present application is further provided with an auxiliary clamping mechanism 10 to further position the metal wire during riveting, effectively improve the accuracy of terminal riveting, and make the riveting of the terminal base and the metal wire more reliable and stable; the specific working principle is as follows: the station moving device 5 moves the metal wire between the upper clamp 105 and the lower clamp 106 of the auxiliary clamping mechanism 10, and at this time, the auxiliary finger cylinder 104 is started to clamp the metal wire. When the terminal base is clamped, the riveting mechanism 61 is started, and the riveting mechanism 61 will descend. At this time, the riveting mechanism 61 will drive the transmission rod 102 to descend, so that the transmission rod 102 is The moving rod 102 will push the auxiliary substrate 101 to descend along the guide column 103, and the auxiliary finger cylinder 104 will descend along with the auxiliary substrate 101, thereby lowering the metal wire clamped by the upper clamp 105 and the lower clamp 106 to the riveting point of the terminal base. When the riveting mechanism 61 contacts the riveting point of the terminal base, it will rivet the terminal base and the metal wire together, thereby completing the terminal riveting operation; then the riveting mechanism 61 rises, the auxiliary clamping mechanism 10 lifts the riveted terminal, and then clamps the terminal through the station moving device 5, and moves to the next station for operation.

[0046] Furthermore, the auxiliary clamping mechanism 10 also includes a limit screw 107 and a return spring 108; the limit screw 107 passes through the auxiliary substrate 101 and is connected to the frame 1; the return spring 108 is sleeved on the outside of the limit screw 107, and the return spring 108 is arranged between the auxiliary substrate 101 and the frame 1, and under the elastic force of the return spring 108, the auxiliary substrate 101 and the frame 1 have a tendency to move away from each other.

[0047] Specifically, when the auxiliary substrate 101 descends, the reset spring 108 will be compressed. When the riveting mechanism 61 rises, the reset spring 108 will bounce the auxiliary substrate 101 upward due to the elastic force, so that the terminal clamped by the upper clamp 105 and the lower clamp 106 rises and leaves the terminal clamping mechanism 62. The limit screw 107 is vertically arranged on the auxiliary substrate 101. The nut part of the limit screw 107 has a limiting effect on the auxiliary substrate 101. When the reset spring 108 bounces the auxiliary substrate 101, the nut part of the limit screw 107 will limit the rise of the auxiliary substrate 101 and prevent the auxiliary substrate 101 from detaching from the guide column 103.

[0049] Specifically, the workstation moving device 5 clamps the metal wire or the riveted terminal through the two clamping pieces 73 and the spacer strips 71, which is not only simple to operate and low in cost, but also has a good clamping effect, and the clamping of the metal wire or the riveted terminal is stable and reliable; in this embodiment, the workstation moving device 5 is provided with 4 groups of the workstation moving devices 5, which can clamp 4 groups of terminals at the same time, and realize 4 workstations working at the same time, which can effectively improve the work efficiency; in specific work, the workstation moving device 5 moves the workstation moving device 5 to the bottom of the terminal, controls the two clamping pieces 73 to separate through the clamp finger cylinder 72, and then controls the workstation moving device 5 to rise, when the metal wire of the terminal falls into the clamping space of the workstation moving device 5, the clamp finger cylinder 72 controls the two clamping pieces 73 to be close and clamped, so as to fix and clamp the terminal, and then moves it through the workstation moving device 5.

[0051] Specifically, when the terminals are assembled and packaged, after being heated by the heating mechanism 66, the unloading motor 82 will start, drive the unloading arm 83 to rotate, so that the unloading fixture 85 is close to the heating mechanism 66 of the terminal assembly device 6. At the same time, the unloading motor 82 will also drive the input gear 841 to rotate, thereby driving the unloading transmission belt 844 to rotate around the input gear 841 and the output gear 842. The rotation of the output gear 842 will drive the output connecting rod 843 to rotate. Since the unloading fixture 85 is arranged on the output connecting rod 85 Therefore, the rotation of the output connecting rod will drive the unloading fixture 85 to rotate, thereby rotating the unloading fixture 85 to an angle suitable for clamping, and clamping the terminal by starting the unloading fixture 85, and then rotating the unloading motor 82 in the opposite direction to drive the unloading fixture 85 away from the heating mechanism 66, and finally moving the terminal to the box for collecting the terminal to complete automatic unloading. The unloading robot 8 of the present invention enables automatic unloading of the assembled terminals, which not only has a simple structure and low cost, but also effectively improves work efficiency while reducing production costs.

[0052] Furthermore, the heat shrink tube packaging mechanism 65 includes a packaging seat 651, a telescopic drive assembly 652, a finger clamp assembly 653 and a packaging pressing assembly 654; the telescopic drive assembly 652 and the packaging pressing assembly 654 are arranged on the packaging seat 651; the finger clamp assembly 653 can be slidably arranged on the packaging seat 651; the finger clamp assembly 653 is arranged at the output end of the telescopic drive assembly 652.

[0053] Specifically, during the working process, the packaging pressing component 654 includes a pressing finger cylinder and a pressing clamp, and the pressing clamp is arranged at the two output ends of the pressing finger cylinder; before inserting the terminal, the transparent heat shrink tube is first placed between the pressing clamps, and when the moving mechanism moves the terminal to the heat shrink tube packaging mechanism 65, the telescopic driving component 652 is started, the finger clamp component 653 is extended and the terminal is clamped, and then the finger clamp component 653 is driven to pull the terminal backward so that the terminal falls into the finger clamp component, and the finger clamp component is started to press and wrap the heat shrink tube around the outside of the terminal. The structure is simple and the working efficiency is high.

[0054] Furthermore, the telescopic drive assembly 652 includes a telescopic drive motor 6521, a drive gear 6522 and a rack slider 6523; the telescopic drive motor 6521 is arranged on the packaging seat 651; the drive gear 6522 is arranged at the output end of the telescopic drive motor 6521; the rack slider 6523 can be slidably arranged on the packaging seat 651; the rack slider 6523 is provided with a drive rack, and the drive rack is meshed and connected with the drive gear 6522; the finger clamp assembly 653 is arranged on the rack slider 6523.

[0055] Specifically, the telescopic driving motor 6521 drives the driving gear 6522 to rotate. Since the driving gear 6522 and the driving rack of the rack slider 6523 are meshed and connected, the rotation of the driving gear 6522 will drive the rack slider 6523 to make a linear translational motion on the packaging seat 651, thereby driving the finger clamp assembly 653 to make a translational motion, so that the finger clamp assembly 653 can move to the position of the terminal to clamp the terminal, with a simple structure and high working efficiency.
