Description

Technical Field

[0001] This invention relates to the field of technology, and in particular to a wire bar terminal crimping machine. Background Technology

[0002] Existing terminal crimping machines are designed for the installation of terminals on single wire connectors. When dealing with multi-terminal wire harnesses, they rely mainly on manual crimping, resulting in low crimping efficiency.

[0003] Furthermore, the existing terminal crimping machines all use linear conveying mechanisms for transferring the material belt, which occupy a lot of space and result in a large overall size of the crimping machine. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a wire bar terminal crimping machine, which reduces the overall size of the machine by setting a rotary transfer device, and can be applied to wire bars that require multi-end crimping, effectively improving crimping efficiency.

[0005] A wire bar terminal crimping machine according to an embodiment of the present invention includes:

[0006] The chassis houses the electrical control devices;

[0007] The conveyor belt feeding device is mounted on the machine casing;

[0008] Peeling and cutting device, the peeling and cutting device is installed on the machine box, and the peeling and cutting device is set at the discharge end of the material belt feeding device;

[0009] The pressing device is mounted on the machine housing and is located at the discharge end of the peeling and cutting device.

[0010] Terminal feeding device, the terminal feeding device is installed on the chassis, the terminal feeding device is set at the crimping end of the crimping device;

[0011] The transfer device is mounted on the chassis and is located between the pressing device and the peeling and cutting device. The transfer device is equipped with a first rotating mechanism and a first gripper mounted on the first rotating mechanism. There are two first grippers, both of which are mounted on the first rotating mechanism and are mirror images of each other.

[0012] According to an embodiment of the present invention, a wire strip terminal crimping machine has at least the following beneficial effects: the machine is equipped with a material strip feeding device and a terminal feeding device, both of which are automatically fed. The material strip is conveyed to a stripping and cutting device for positioning and cutting, and the outer skin of the part of the material strip to be crimped with the terminal is removed. Subsequently, a transfer device clamps and transfers the stripped material strip to the crimping device for crimping. When the terminal material strip is conveyed to the crimping device by the terminal feeding device, the crimping device starts to crimp the terminal to the material strip. It is important to note that the transfer device is equipped with a first rotating mechanism and two first grippers. The first grippers are mirror images of the first rotating mechanism. When the first gripper on one side of the first rotating mechanism clamps the strip on the peeling and cutting device, the first rotating mechanism is activated, switching the positions of the two first grippers. At this time, the first gripper holding the strip is switched to the crimping device, while the first gripper on the other side that is not holding the strip is switched to the peeling and cutting device to wait for and clamp the next strip that has been cut and peeled. This alternation effectively reduces the space occupied by the transfer device in the whole machine and improves the transfer efficiency, thus effectively improving the production efficiency.

[0013] According to an embodiment of the present invention, a wire strip terminal crimping machine is further provided on the machine casing, and the positioning device is disposed between the stripping and cutting device and the crimping device. The positioning device is used to accurately determine the stripping position and the cutting position to determine the length of the strip and the starting position for stripping.

[0014] According to an embodiment of the present invention, a wire strip terminal crimping machine includes a positioning device comprising a CCD camera and an alignment mechanism. The alignment mechanism has a channel for the material strip to pass through, and the CCD camera is mounted above the channel. The CCD camera, the alignment mechanism, and an electronic control device are electrically connected. The inlet of the alignment mechanism is connected to the outlet of a peeling and cutting device. After the CCD camera captures an image of the material strip entering the channel, it transmits the information to the electronic control device. Under preset parameters, the alignment mechanism adjusts the width of the channel so that the material strip is positioned in the middle of the channel and its position matches the peeling and cutting device, ensuring accurate cutting length and peeling position of the material strip, and thus ensuring product processing quality.

[0015] According to an embodiment of the present invention, a wire strip terminal crimping machine has an alignment mechanism consisting of two identical clamping blocks and a first drive. The two clamping blocks are mirror-aligned to form a channel, and the two first drives are respectively connected to the two clamping blocks. The first drives increase or decrease the distance between the clamping blocks. After the CCD camera positions the material strip in the channel, the electronic control device outputs a signal to the first drive, which then activates and changes the distance between the clamping blocks to change the width of the channel. The structure is simple and practical.

[0016] According to an embodiment of the present invention, a wire strip terminal crimping machine includes a stripping and cutting device comprising a stripping mechanism and a cutting mechanism, which are arranged sequentially along the conveying direction of the material strip. A CCD is mounted on the stripping mechanism, which is mounted on a aligning mechanism, and the cutting mechanism is mounted at the feeding end of the aligning mechanism.

[0017] According to an embodiment of the present invention, a wire strip terminal crimping machine further includes a feeding device, which is disposed on a machine housing. The feeding device includes a second rotating mechanism and a second gripper mounted on the second rotating mechanism. The second rotating mechanism is electrically connected to an electrical control device. After the material strip is crimped with the terminal, the second gripper clamps the processed material strip away from the crimping device, and simultaneously, the second rotating mechanism is activated to carry the material strip away from the crimping device.

[0018] According to an embodiment of the present invention, a wire strip terminal crimping machine includes a feeding device further comprising a hopper disposed on a machine housing and a conveyor belt disposed at the bottom of the hopper. A second rotating mechanism is mounted above the hopper and reciprocates between the hopper and the crimping device. When the second rotating mechanism brings the processed strip to the top of the hopper, the second gripper opens, and the strip falls naturally into the hopper. It should be noted that the two side walls of the hopper are inclined. When the strip falls into the hopper, the inclined side walls allow the strip to slide onto the conveyor belt at the bottom of the hopper, and then the conveyor belt transports the strip to a container for loading the strip.

[0019] According to an embodiment of the present invention, a wire strip terminal crimping machine includes a strip feeding device comprising a tensioning mechanism and a feeding mechanism. The discharge end of the tensioning mechanism is connected to the feed end of the peeling and cutting device, and the discharge end of the feeding mechanism is connected to the feed end of the tensioning mechanism. Specifically, the tensioning mechanism includes a frame and a guide wheel assembly mounted on the frame. The guide wheel assembly includes an upper wheel assembly and a lower wheel assembly, which are offset from each other. Furthermore, both the upper and lower wheel assemblies are equipped with a second drive, which causes the upper and lower wheel assemblies to rotate, thus both conveying and tensioning the strip.

[0020] According to an embodiment of the present invention, a wire terminal crimping machine includes a feeding mechanism comprising a first lifting mechanism and a feeding rack mounted on the first lifting mechanism. The feeding rack includes a mounting plate and a support rod disposed on the mounting plate. One end of the support rod is connected to the mounting plate, and a limit block is disposed at the end of the support rod away from the mounting plate. The limit block is detachably connected to the support rod. The material reel to be processed is fixed on the feeding rack. Specifically, after the support rod passes through the through hole of the material reel, the worker adjusts the position of the limit block on the support rod to fix the material reel on the feeding rack, preventing the material reel from falling off during rotation.

[0021] According to an embodiment of the present invention, a wire strip terminal crimping machine includes a transfer device further comprising a translation mechanism and a second lifting mechanism. The translation mechanism is mounted on a chassis, the second lifting mechanism is mounted on the translation mechanism, and a first rotating mechanism is mounted on the second lifting mechanism. The translation mechanism and the lifting mechanism are used to adjust the position of the first rotating mechanism so that the first gripper can accurately grip the material strip.

[0043] Reference Figures 1 to 4This invention provides a wire strip terminal crimping machine, including a chassis 100 with an electrical control device; a strip feeding device 200 mounted on the chassis 100; a strip peeling and cutting device 300 mounted on the chassis 100 and located at the outlet end of the strip feeding device 200; and a crimping device 400 mounted on the chassis 100 and located at the outlet end of the strip peeling and cutting device 300. The terminal feeding device... Terminal feeding device 500 is mounted on the chassis 100 and is located at the crimping end of crimping device 400; transfer device is mounted on the chassis 100 and is located between crimping device 400 and peeling and cutting device 300. The transfer device is equipped with a first rotating mechanism 600 and a first gripper 610 mounted on the first rotating mechanism 600. There are two first grippers 610, and both first grippers 610 are mounted on the first rotating mechanism 600 and are mirror images of each other.

[0044] The system is equipped with a material strip feeding device 200 and a terminal feeding device 500. Both the material strip and the terminal strip are automatically fed. The material strip is conveyed to the peeling and cutting device 300 for positioning and cutting, and the outer skin of the part of the material strip to be crimped with the terminal is removed. Then, the transfer device clamps and transfers the peeled material strip to the crimping device 400 for crimping. When the terminal material strip is conveyed to the crimping device 400 by the terminal feeding device 500, the crimping device 400 starts to crimp the terminal to the material strip. It is important to note that the transfer device is equipped with a first rotating mechanism 600 and two first grippers 610. The first grippers 610 are mirror images of the first rotating mechanism 600. When one of the first grippers 610 on the first rotating mechanism 600 clamps the strip on the peeling and cutting device 300, the first rotating mechanism 600 is activated, switching the positions of the two first grippers 610. At this time, the first gripper 610 holding the strip is switched to the crimping device 400, while the other first gripper 610 not holding the strip is switched to the peeling and cutting device 300 to wait for and clamp the next strip that has been cut and peeled. This alternation effectively reduces the space occupied by the transfer device in the whole machine and improves the transfer efficiency, thus effectively improving the production efficiency.

[0045] According to some embodiments of this application, a positioning device is also provided on the chassis 100, which is located between the peeling and cutting device 300 and the crimping device 400. The positioning device is used to accurately determine the peeling position and the cutting position to determine the length of the material strip and the starting position for peeling. Specifically, the positioning device includes a CCD camera 700 and a straightening mechanism 800. The straightening mechanism 800 is provided with a channel 810 for the material strip to pass through. The CCD camera 700 is mounted above the channel 810. The CCD camera 700, the straightening mechanism 800, and the electronic control device are electrically connected. The inlet of the alignment mechanism 800 is connected to the outlet of the peeling and cutting device 300. After the CCD camera 700 takes a picture of the material strip entering the channel 810, it transmits the information to the electronic control device. Under the preset parameters, the alignment mechanism 800 adjusts the width of the channel 810 so that the material strip is in the middle of the channel 810 and the position of the material strip matches the peeling and cutting device 300, so as to ensure the accuracy of the cutting length and peeling position of the material strip and ensure the processing quality of the product.

[0046] According to some embodiments of this application, the crimping device 400 includes a crimping head 410, a crimping drive 420, an X-axis moving mechanism 430, and a crimping table 440. Specifically, the crimping table 440 is mounted on the chassis 100, wherein the crimping table 440 is provided with receiving slots 441 corresponding to the number of cable tray ends to be crimped. The X-axis moving mechanism 430 is mounted above the crimping table 440. Further, the crimping drive 420 is mounted on the X-axis moving mechanism 430, the crimping head 410 is mounted on the crimping drive 420, and the crimping drive 420 is electrically connected to an electronic control device, such as... Figure 3 As shown, the X-axis moving mechanism 430 drives the crimping head 410 to move horizontally and crimp the terminals sequentially. Furthermore, a recycling mechanism 1000 for recycling waste materials is provided at the end of the crimping table 440 away from the terminal feeding mechanism; specifically, the recycling mechanism 1000 is a tubular structure.

[0047] According to some embodiments of this application, the alignment mechanism 800 consists of two identical clamping blocks 820 and a first drive 830. The two clamping blocks 820 are mirror-mounted to form a channel 810. The two first drives 830 are respectively connected to the two clamping blocks 820, and the first drives 830 increase or decrease the distance between the clamping blocks 820. After the CCD camera 700 positions the material strip in the channel 810, the electronic control device outputs a signal to the first drive 830, which then activates and changes the distance between the clamping blocks 820 to change the width of the channel 810. The structure is simple and practical.

[0048] According to some embodiments of this application, the peeling and cutting device 300 includes a peeling mechanism 310 and a cutting mechanism 320, which are arranged sequentially along the conveying direction of the material belt. A CCD is mounted on the peeling mechanism 310, which is mounted on a aligning mechanism 800. The cutting mechanism 320 is located at the feed end of the aligning mechanism 800. Specifically, the peeling blade 311 on the peeling mechanism 310 is provided with a groove 312 corresponding to the position of the wire strip to be peeled, and the grooves 312 are spaced apart along the length of the peeling blade 311.

[0049] According to some embodiments of this application, a feeding device 900 is disposed on a housing 100. The feeding device 900 includes a second rotating mechanism 910 and a second gripper 920 mounted on the second rotating mechanism 910. The second rotating mechanism 910 is electrically connected to an electrical control device. After the material strip is crimped with the terminal, the second gripper 920 clamps the processed material strip away from the crimping device 400. At the same time, the second rotating mechanism starts to carry the material strip away from the crimping device 400. The feeding device 900 also includes a collecting hopper 930 disposed on the housing 100 and a conveyor belt 940 disposed at the bottom of the collecting hopper 930. The second rotating mechanism 910 is mounted above the collecting hopper 930 and reciprocates between the collecting hopper 930 and the crimping device 400. After the second rotating mechanism 910 brings the processed material strip to the top of the collecting hopper 930, the second gripper 920 opens, and the material strip falls naturally into the collecting hopper 930. It should be noted that the two side walls of the collecting hopper 930 are designed to be inclined. When the material strip falls into the collecting hopper 930, the inclined side walls allow the material strip to slide down to the conveyor belt 940 at the bottom of the collecting hopper 930. Then the conveyor belt 940 transports the material strip to the box used to load the material strip.

[0050] According to some embodiments of this application, the conveyor belt feeding device 200 includes a tensioning mechanism 210 and a feeding mechanism 220. The discharge end of the tensioning mechanism 210 is connected to the feed end of the peeling and cutting device 300, and the discharge end of the feeding mechanism 220 is connected to the feed end of the tensioning mechanism 210. Specifically, the tensioning mechanism 210 includes a frame and a guide wheel assembly mounted on the frame. The guide wheel assembly includes an upper wheel assembly and a lower wheel assembly, which are offset from each other. In addition, both the upper wheel assembly and the lower wheel assembly are provided with a second drive, which causes the upper wheel assembly and the lower wheel assembly to rotate, thereby tensioning the conveyor belt while simultaneously conveying it.

[0051] According to some embodiments of this application, the material placement mechanism 220 includes a first lifting mechanism 221 and a material placement rack mounted on the first lifting mechanism 221. The material placement rack includes a mounting plate 222 and a support rod 223 disposed on the mounting plate 222. One end of the support rod 223 is connected to the mounting plate 222, and a limit block 224 is provided at the end of the support rod 223 away from the mounting plate 222. The limit block 224 is detachably connected to the support rod 223. The material reel to be processed is fixed on the material placement rack. Specifically, after the support rod 223 passes through the through hole of the material reel, the worker adjusts the position of the limit block 224 on the support rod 223 to fix the material reel on the material placement rack, preventing the material reel from falling off when rotating.

[0052] According to some embodiments of this application, the transfer device is further provided with a translation mechanism 620 and a second lifting mechanism 630. The translation mechanism 620 is mounted on the housing 100, the second lifting mechanism 630 is mounted on the translation mechanism 620, and the first rotating mechanism 600 is mounted on the second lifting mechanism 630.
