Description

Technical Field

[0001] The utility model relates to the technical field of crimping machines, in particular to an automatic wire terminal crimping machine. Background Art

[0002] With the development of electronic product technology, electronic products have gradually become modularized. As the amount of information transmitted between modules increases, modules are usually connected by cables. When using cables, terminals are usually pressed on the cables, and then the cables with terminals are installed in connectors. At this time, in order to increase the connection speed of the terminals, corresponding terminal crimping machines are often used to fix the cables and install the terminals at the cable ports.

[0003] During the actual use of the terminal crimping machine, the operator fixes the cable with the required terminal installation at the bottom of the crimping machine, and then a terminal reel is set on the top of the crimping machine to continuously transport the terminal to the bottom of the crimping machine for pressing. During this process, the terminal reel is rotatably installed on the top of the crimping machine. When installing the terminal reel, it will be inserted into the surface of the fixed shaft, and then the threaded sleeve is used from the front side of the fixed shaft to screw and fix it. Once the inner diameter of the plug-in hole inside the terminal reel does not match the diameter of the fixed shaft, it is very easy to cause the terminal reel to be unable to rotate synchronously when the shaft rotates, thereby affecting the terminal feeding. When the terminal reel is disassembled and replaced, the operator needs to manually screw and move the threaded sleeve on the front side before the terminal reel can be disassembled. This is time-consuming and labor-intensive, affecting the efficiency of terminal reel replacement and thus affecting the efficiency of cable installation. To this end, a new technical solution needs to be designed to solve this problem. Utility Model Content

At the same time, when the terminal reel is disassembled and replaced, the operator needs to manually twist and move the threaded sleeve on the front side before the terminal reel can be disassembled, which is time-consuming and labor-intensive, affecting the efficiency of terminal reel replacement and thus affecting the efficiency of cable arrangement and installation.

[0013] Preferably, movable grooves are provided inside both ends of the side of the hollow tube, and the push rod is inserted into the movable groove through sliding, and each side surface of the arc plate is fixedly bonded with an anti-slip friction pad.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model is provided with a sliding plate rotatably arranged on the side of the support plate vertically arranged on the top of the crimping machine housing, and a hollow insert is installed on the surface of the sliding plate, and abutting arc plates are movably provided on both sides of the outside of the hollow insert, so that after the terminal reel is sleeved on the hollow insert and the outside of the abutting arc plate, the operator only needs to control the operation of the servo motor so that the servo motor drives the bidirectional screw rod to rotate inside the hollow insert, and the driving sleeves sleeved on both sides of the outside of the bidirectional screw rod can move horizontally inside the hollow insert synchronously or relative to each other under the guiding and limiting effect of the movable groove on the push rod, and then the two ends of the push rod are hinged to the hinged action of the rotating shaft.

[0026] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0027] Example 1: Automatic cable terminal crimping machine, see Figures 1 to 4 , a material guide frame 11 is fixedly installed on the side of the shell 1, and a material stopper 12 is fixedly installed on the outer surface of both ends of the material guide frame 11. A support plate 13 is fixedly installed vertically on the top of the outer side of the shell 1, and a transmission plate 42 is slidably installed on the side of the support plate 13. A sliding plate 2 is slidably installed on the other side of the support plate 13. The sliding plate 2 and the transmission plate 42 are rotatably connected. A hollow cannula 21 is fixedly installed on the side of the sliding plate 2, and the outer ends of the hollow cannula 21 are movably fitted with a tight arc plate 22. An adjustment mechanism is provided inside the hollow cannula 21, and the adjustment mechanism is transmission-connected to the tight arc plate 22. Guide mechanisms are provided on both sides of the outside of the sliding plate 2, and the guide mechanism is transmission-connected to the tight arc plate 22. The support plate 1 3 A pushing mechanism is vertically arranged on the top of the side, and the pushing mechanism is connected to the transmission plate 42 by transmission. The position of the pressing arc plate 22 is adjusted by the adjusting mechanism, and the movement of the pressing arc plate 22 is guided by the guiding mechanism, so that the pressing arc plate 22 can be adjusted for applicability according to the inner diameter of the terminal reel, ensuring that the pressing arc plate 22 can fully fit the inner wall of the terminal reel for use and reinforcement. When disassembling and replacing it, the operator only needs to reversely drive the servo motor 27 to disengage the pressing arc plate 22 from the inner wall of the terminal reel and quickly and conveniently remove it, thereby improving the efficiency of disassembling and assembling the terminal reel.

[0028] For details, see Figures 1 to 4The adjusting mechanism includes a bidirectional screw 23 and a push rod 26. The bidirectional screw 23 is rotatably installed at the middle end of the inner side of the hollow cannula 21 through a bearing. The two sides of the outer side of the bidirectional screw 23 are connected with a transmission sleeve 24 through a threaded sleeve. Each transmission sleeve 24 and the outer side of the tight arc plate 22 are fixedly installed with a connecting frame 25. The sides of each two groups of connecting frames 25 are hinged with a push rod 26 by a rotating shaft. A servo motor 27 is fixedly installed at one end of the inner side of the hollow cannula 21 away from the support plate 13, and the side of the servo motor 27 drive shaft is connected by a coupling and a bidirectional screw 2 3 sides are fixedly connected, and under the rotational transmission action of the bidirectional screw 23 on the transmission sleeve 24 and the transmission conversion action of the push rod 26, when the bidirectional screw 23 adjusts the horizontal movement of the transmission sleeve 24, the push rod 26 can convert the horizontal movement force of the transmission sleeve 24 into a lateral push-pull force on the tight arc plate 22, thereby making the tight arc plate 22 adaptable to different terminal reel inner diameters, ensuring that terminal reels with different inner diameters can be stably sleeved on the outside of the hollow insert 21 for feeding use.

[0029] For further information, see Figures 1 to 4 A connecting block 43 is fixedly installed on the middle end of the side of the transmission plate 42, a sliding groove 5 is vertically opened at the middle end of the support plate 13, and the connecting block 43 is slidably inserted into the sliding groove 5, and a rotating block 14 is fixedly installed on the side of the sliding plate 2, and the rotating block 14 is rotatably installed inside the connecting block 43 through a bearing. By rotatably installing the rotating block 14 inside the connecting block 43, the rotating block 14 can rotate on the side of the connecting block 43 and can drive the sliding plate 2 and the hollow insert 21 to rotate synchronously, and then the terminal reel sleeved on its surface can be rotated synchronously to reel up the material.

[0030] It is worth noting that, see Figures 1 to 4 The guide mechanism includes a guide slot 32 and a guide slider 31. The guide plates 3 are fixedly installed on the two end surfaces of the side of the sliding plate 2. A guide slot 32 is opened horizontally at the middle end of each guide plate 3. A guide slider 31 is fixedly installed on the side of each tight arc plate 22 close to the sliding plate 2, and the guide slider 31 is slidably inserted into the guide slot 32. The vertical sections of the guide slider 31 and the guide slot 32 are both T-shaped. By arranging the guide slider 31 on the side of the tight arc plate 22 and combining the guiding sliding action of the guide slot 32 on the guide slider 31, the tight arc plate 22 will not arbitrarily separate from the surface of the guide plate 3. At the same time, the tight arc plate 22 can only move horizontally along the outer wall of the guide plate 3 when pushed.

[0031] It is worth noting that see Figures 1 to 4The pushing mechanism includes an electric push rod 41, a fixed plate 4 is fixedly installed on the top side of the support plate 13, and an electric push rod 41 is vertically fixedly installed on the middle end of the bottom of the fixed plate 4, and the bottom of the transmission shaft of the electric push rod 41 is fixedly connected to the top of the transmission plate 42. Through the structural action of the electric push rod 41, it can be operated to provide corresponding driving force to the transmission plate 42, thereby driving the sliding plate 2 and the hollow insert 21 to adjust the vertical position, avoiding the gap between the hollow insert 21 and the outside of the shell 1 being too small, resulting in the terminal reel with too large size being unable to be fixed on the outside of the hollow insert 21, further improving the processing applicability of the overall mechanism.

[0032] It is worth mentioning that see Figures 1 to 4 , movable grooves 28 are opened inside the two ends of the side of the hollow tube 21, and the push rod 26 is slidably inserted into the movable groove 28. Each side surface of the tight arc plate 22 is fixedly bonded with an anti-slip friction pad 29. Through the guiding and limiting effect of the movable groove 28 on the push rod 26, when the bidirectional screw rod 23 rotates, the transmission sleeve 24 will not rotate axially but can only move horizontally toward or relative to its surface, thereby providing the power required for the movement of the tight arc plate 22.

[0033] During operation, when it is necessary to press-connect the side end of the cable and the terminal, according to the overall diameter of the terminal reel, the electric push rod 41 is turned on by the external control switch, so that it is operated and the transmission plate 42 is driven to move vertically. Combined with the guiding sliding action of the sliding groove 5 on the connecting block 43, the connecting block 43 and the rotating block 14 can move vertically synchronously inside the sliding groove 5 as the transmission plate 42 moves, thereby providing a corresponding vertical driving force to the sliding plate 2 and the hollow insert 21, adjusting the gap between the hollow insert 21 and the top surface of the shell 1. The spacing is such that when the terminal reel is pushed into and sleeved on the outside of the hollow insert 21, the bottom of the terminal reel will not fit on the outside of the shell 1 and cannot be rotated to transport the terminal. Then, the servo motor 27 is turned on by the external control switch to drive the bidirectional screw rod 23 to rotate synchronously inside the hollow insert 21. Combined with the guiding and limiting effect of the movable groove 28 on the push rod 26, the transmission sleeves 24 sleeved on both sides of the outside of the bidirectional screw rod 23 can move horizontally inside the hollow insert 21 synchronously. The combined transmission conversion effect of the push rod 26 can provide a corresponding outward driving force to the arc plate 22, and the combined guide slider 31 on the side of the arc plate 22 can slide in the guide groove 32 inside the guide plate 3, so that the arc plate 22 can move horizontally relative to the outside of the guide plate 3 until the anti-slip friction pad 29 on the outside of the arc plate 22 is fully fitted and pressed against the inner wall of the terminal reel, and the terminal reel sleeved on the outside of the hollow insert 21 is fixed in position, and then the terminal inside the terminal reel is pulled. The terminal is moved out from the inside of the reel, so that the outer side of the terminal moves to the bottom of the shell 1 under the guidance of the material guide frame 11 and the material stop frame 12, and then the terminal is crimped to the side end of the cable under the operation of the pressing component inside the shell 1. After the material inside the terminal reel is consumed, the operator only needs to control the servo motor 27 to operate in reverse and repeat the above transmission steps to make the clamping arc plate 22 move toward each other and detach from the inner wall of the terminal reel and lose the clamping limiting force on it. The terminal reel can then be quickly and conveniently removed for material replacement.
