[0048] Reference Figure 1-7 In one embodiment of the present invention, a terminal processing device for a plug head is used to trim a terminal outer shape 800, wherein the terminal outer shape 800 includes a fixed end 810 and a connection end 820 connected to each other, and a through hole 811 is provided on the fixed end 810 that penetrates the thickness direction thereof. The plug head special terminal processing device includes:
[0049] A CNC machining center 100 comprises a driving spindle 110, a two-dimensional motion table 120, a turning tool assembly 130 and a milling cutter assembly 140, wherein the driving spindle 110 is provided with a first double-jaw chuck 111, and two first chuck hands are relatively provided on the first double-jaw chuck 111, the turning tool assembly 130 comprises a turning tool base 131 and a first turning tool 132 provided on the turning tool base 131, and the milling cutter assembly 140 comprises a milling cutter base 141 and a first milling cutter 142 provided on the milling cutter base 141, the turning tool base 131 and the milling cutter base 141 are provided on the two-dimensional motion table 120, the motion plane of the two-dimensional motion table 120 is a first working plane, the two-dimensional motion direction of the two-dimensional motion table 120 is along the length direction of the driving spindle 110 and perpendicular to the length direction of the driving spindle 110, and the milling cutter assembly 140 is provided to telescopically move in a direction perpendicular to the first working plane;
[0050] The transfer assembly 200 is matched with the CNC machining center 100 and includes a track 210 and a sampling part 220. The track 210 is arranged above the CNC machining center 100. The sampling part 220 includes an operating base 221 and a telescopic gripper assembly 222 which is telescopically arranged on the operating base 221. The operating base 221 is reciprocatingly arranged on the track 210. The end of the telescopic gripper assembly 222 is a gripper 223.
[0051] Wherein, the gripper 223 enters and exits the CNC machining center 100 through the extension and retraction of the telescopic gripper assembly 222 .
[0052] In the prior art, cable terminals are mostly processed by turning, milling and other forging processes on bars to form them. The above process has problems of large amount of waste and low processing efficiency. At the same time, there are also a small number of cases where cold extrusion process is used. Due to the processing characteristics of cold extrusion, it is difficult to achieve direct forming at the chamfer position (the forming effect is not good or the mold is easily damaged). Therefore, the workpiece after cold extrusion processing still needs to be trimmed. That is, no matter whether the terminal shape part 800 is processed by turning or milling or by cold extrusion, shape trimming is required.
[0053] Specifically in the present invention, the CNC machining center 100 is used to perform shape trimming on the terminal outer shape part 800 at various positions, including the outer periphery trimming of the connection end 820, the chamfering of the transition zone 830 between the fixed end 810 and the connection end 820, the chamfering of the through hole 811 on the fixed end 810, and the chamfering of part of the edge area of the fixed end 810. The chamfering of the transition zone 830 and the chamfering of the through hole 811 are directly completed at the position of the first double-jaw chuck 111, eliminating the transportation and clamping time loss caused by introducing a separate device to chamfer the through hole 811. In this embodiment, when the driving spindle 110 drives the terminal outer shape part 800 to rotate, the turning tool assembly 130 is used to chamfer the transition zone 830; when the driving spindle 110 is in a stopped state, the milling cutter assembly 140 is used to chamfer the through hole 811. Because the first double-jaw chuck 111 can make it possible to retain space for chamfering the through hole 811 on the fixed end 810 and chamfering part of the edge area of the fixed end 810 while clamping the terminal shape part 800. In the present invention, the CNC machining center 100 is specifically designed, and the turning tool base 131 and the milling cutter base 141 share the two-dimensional motion table 120, which efficiently realizes the position movement in two directions, saves the space in the CNC machining center 100, and provides the possibility for the multi-functional realization of the CNC machining center 100 and the operation of the transfer assembly 200. During the operation of the turning tool assembly 130, due to the movement direction characteristics of the two-dimensional motion table 120, the turning tool assembly 130 can chamfer the outer periphery of the terminal shape part 800 (such as the transition area 830 on the terminal shape part 800). When the milling cutter assembly 140 adds a movement dimension perpendicular to the direction of the first working surface, the movement mode of the milling cutter assembly 140 can perform chamfering operations at relevant positions of the terminal shape part 800.
[0054] In the present invention, the various trimming steps are integrated into the CNC machining center 100, thereby achieving the effect of improving machining efficiency, and the structural complexity within the CNC machining center 100 is slightly increased; at the same time, the CNC machining center 100 is matched with a transfer assembly 200, which improves the degree of automation of the terminal processing device dedicated to the plug head; the first double-jaw chuck 111 allows space to trim the terminal outer shape 800 while clamping the terminal outer shape 800.
[0055] Reference Figure 1-7 In one embodiment, the grabbing hand 223 includes a turntable 224 and two grabbing cards 225 arranged on the turntable 224. The two grabbing cards 225 are arranged at 90 degrees. A turntable driving unit is arranged corresponding to the turntable 224. Through the rotation of the turntable 224, the two grabbing cards 225 alternately operate to the end position of the telescopic grabbing hand assembly 222.
[0056] In the conventional process, when a plurality of terminal shape parts 800 are neatly arranged, they are mostly in an upright state, and the fixing direction of the terminal shape parts 800 on the first double-jaw chuck 111 is horizontal, which involves the problem of changing the direction of the terminal shape parts 800; of course, in order to improve the processing efficiency, the gripper 223 is preferably able to simultaneously clamp the terminal shape parts 800 to be trimmed and the trimmed terminal shape parts 800. In this embodiment, the two gripper cards 225 can simultaneously grasp the terminal shape parts 800 to be trimmed and the trimmed terminal shape parts 800, and the turntable 224 is at a 45-degree angle to the vertical direction. By rotating the turntable 224, the direction of the terminal shape parts 800 can be changed from horizontal to vertical.
[0057] In a typical process, the grabbing arm 223 moves to the sampling position, and one of the two grabbing cards 225 is in a vertical direction, so that it can grab the upright terminal shape part 800 to be trimmed; the grabbing arm 223 retracts into the operating base 221, and the operating base 221 is transferred to the top of the first double-jaw chuck 111 on the track 210; when the CNC machining center 100 completes the trimming of the terminal shape part 800, the grabbing arm 223 extends out of the operating base 221, and the grabbing card 225 in a horizontal position grabs the trimmed terminal shape part 800, and then the turntable drive unit drives the turntable 224 to rotate 90 degrees, and the grabbing arm 223 can deliver the terminal shape part 800 to be trimmed into the first double-jaw chuck 111; the grabbing arm 223 retracts into the operating base 221, and after moving to the sampling position again, the grabbing card 225 in a vertical direction puts down the trimmed terminal shape part 800, and grabs the next terminal shape part 800 to be trimmed.
[0058] Reference Figure 8-11 In one embodiment, the CNC machining center 100 further includes a driving sub-axis 150 parallel to the driving main axis 110, the straight-line distance between the driving sub-axis 150 and the driving main axis 110 is H, a second double-jaw chuck 151 is arranged on the driving sub-axis 150, and two second chuck hands are arranged oppositely on the second double-jaw chuck 151;
[0059] The turning tool base 131 is provided with a second turning tool 133, and the spatial position relationship between the second turning tool 133 and the first turning tool 132 corresponds to the position relationship between the driving main shaft 110 and the driving secondary shaft 150. The milling cutter base 141 is provided with a second milling cutter 143, and the spatial position relationship between the second milling cutter 143 and the first milling cutter 142 corresponds to the position relationship between the driving main shaft 110 and the driving secondary shaft 150. The grabbing card 225 is provided with two grabbing positions 226 set at a distance H. When the grabbing card 225 runs to the end position of the telescopic gripper assembly 222, the spacing direction of the two grabbing positions 226 is consistent with the length direction of the track 210.
[0060] During the production process, the CNC machining center 100 takes a long time to trim a single terminal shape part 800, and during the trimming process, the machining force of the turning tool assembly 130 or the milling tool assembly 140 on the terminal shape part 800 is not large. The research believes that it can be developed in a single CNC machining center 100 to trim two terminal shape parts 800 at the same time. In this embodiment, a driving sub-shaft 150 is added to the CNC machining center 100; combined with the rotation characteristics of the grabber 223, two grabbing positions 226 are set on the grabber card 225, so that two terminal shape parts 800 can be taken and placed at the same time, and the structural complexity remains basically unchanged, doubling the processing efficiency. The driving sub-shaft 150 can have its own driving motor or be driven by the driving main shaft 110. Preferably, the driving sub-shaft 150 is driven by the driving main shaft 110 through a gear transmission structure or a belt transmission structure.
[0061] Reference Figure 1-7 In one embodiment, the special terminal processing device for the plug head also includes a first sample holding component 300, and the first sample holding component 300 is matched with the transfer component 200. The first sample holding component 300 includes a first sample holding plate 310 and a first drive component 320. The first sample holding component 300 is provided with a plurality of first sample loading positions arranged in a rectangular array. The first drive component 320 drives the first sample holding plate 310 to reciprocate and the direction is perpendicular to the length direction of the track 210, wherein one direction in which the plurality of first sample loading positions are arranged in a rectangular array is parallel to the direction of the track 210.
[0062] In the present embodiment, the setting direction of the track 210 is consistent with the length direction of the driving spindle 110 (the length direction of the driving spindle 110 is defined as the length direction of the CNC machining center 100 in the present invention), and the track 210 is set above the CNC machining center 100; in order to enable the grabber 223 to take samples from the outside and put them into the first double-jaw chuck 111, the grabber 223 needs to be able to move along the track 210 and telescopically move in the vertical direction, that is, the grabber 223 can move in two dimensions. In general, the terminal shape member 800 is placed at one end of the length direction of the CNC machining center 100 and arranged in a neat array. If the first sample holding component 300 does not exist, the grabber 223 of the transfer component 200 needs to be able to move in three dimensions in order to realize automated sampling, that is, it is necessary to add a movement dimension in the direction perpendicular to the track 210, so the structural complexity of the transfer component 200 is increased and the operation efficiency is reduced. In this embodiment, a first sample holding component 300 is added, and the placement of the terminal outer shape 800 is standardized through the first sample holding plate 310. At the same time, the first drive component 320 is used to achieve one-dimensional movement, which simplifies the movement mode and physical structure of the transfer component 200, so that the overall operation efficiency of the plug-in head dedicated terminal processing device can be improved. The numerous first sample loading positions arranged on the first sample holding plate 310 reduce the frequency of manual operation of the first sample holding plate 310. The first drive component 320 can be a screw mechanism, a belt mechanism, or a pneumatic hydraulic mechanism.
[0063] Reference Fig.14 In one embodiment, the terminal processing device dedicated to the plug-in head also includes a direct vibration feeder, which includes a feeder main body and a feeding track portion 700 arranged on the feeder main body, and the setting of the feeding track portion 700 is consistent with the length direction of the track 210. Both sides of the width direction of the feeding track portion 700 are respectively limiting walls 710, and a blocking plate 720 is arranged at the end of the length direction of the feeding track portion 700, and a discharge port 730 is formed between the blocking plate 720 and the bottom of the feeding track portion 700.
[0064] In this embodiment, a direct vibration feeder is used to realize the conveying of the terminal shape part 800. The terminal shape part 800 is driven on the conveying track part 700 and blocked at the blocking plate 720. The grabber 223 grabs the terminal shape part 800 at a specific position (which can be a preset position or a position recognized by an image). It should be noted that in this embodiment, due to the special shape of the terminal shape part 800, it cannot be stably upright by itself, and a transfer tool 600 is required to be used. After the fixed end 810 is placed in the transfer tool 600, the terminal shape part 800 is regularly upright; when the terminal shape part 800 is taken away by the grabber 223 of the transfer component 200, the terminal shape part 800 is removed from the discharge port 730. The working process of the above direct vibration feeder is simple and efficient. In order to limit the orientation of the terminal shape part 800 on the conveying track part 700, the cross section of the transfer tool 600 is preferably made into a rectangle. In actual use, the start-up of the direct vibration feeder may be intermittent, and the intermittent setting may be implemented according to time rules and / or sensor information, thereby reducing the energy consumption of the direct vibration feeder. In the implementation process, the top of the limiting wall 710 may be provided with an undercut structure, which limits the transfer fixture 600 from being separated from the feeding track portion 700 in the vertical direction.
[0065] Reference Figures 12 to 13 In one embodiment, the plug-head dedicated terminal processing device further comprises:
[0066] A cold extrusion device, used for cold extruding the raw material block into the terminal shape member 800;
[0067] A multi-axis manipulator device is matched with the cold extrusion device and is used to place the raw material block into the cold extrusion device and take the terminal shape member 800 out of the cold extrusion device.
[0068] In this embodiment, the terminal shape part 800 is processed by a cold extrusion device, which has the advantages of high production efficiency and low material loss. The use of a multi-axis manipulator device to perform the operations of picking up and placing parts liberates human resources. The specific multi-axis manipulator device can adopt preset position clamping or image (visual) recognition clamping. The specific multi-axis manipulator device can adopt FANUC's intelligent vision six-axis robot arm, which not only can realize the visual function, but also facilitates personalized expansion, such as adding purge and other functions at the end of the robot arm. The driving force of the cold extrusion device can be realized by hydraulic means or the like. The cold extrusion device is not limited to one, and the molding process of the terminal shape part 800 can be realized in one device, or the molding process of the terminal shape part 800 can be completed in steps in multiple devices.
[0069] Reference Figures 12 to 13In one embodiment, the cold extrusion device includes a first cold extrusion part 410 and a second cold extrusion part 420 , wherein the first cold extrusion part 410 is used to independently process the fixed end 810 , and the second cold extrusion part 420 is used to independently process the connecting end 820 .
[0070] After analysis of production practice, due to the thin thickness of the fixed end 810, the material flow of the raw material block is more intense. At this time, if the fixed end 810 and the connecting end 820 are processed in one extruder, the fixed end 810 and the connecting end 820 are prone to poor molding, and the consumption of the mold is also aggravated, especially when the size of the plug-in terminal 900 is large (the length dimension is generally more than 7 cm). In this embodiment, the cold extrusion process of the terminal shape member 800 is divided into two steps, which are independently performed at the first cold extrusion part 410 and the second cold extrusion part 420, so that the processing effect of the fixed end 810 and the connecting end 820 can be guaranteed. In the specific processing process, the processing order of the fixed end 810 and the connecting end 820 is not limited. The fixed end 810 can be first processed at the first cold extrusion part 410, and then the connecting end 820 can be processed at the second cold extrusion part 420; similarly, the connecting end 820 can be first processed at the second cold extrusion part 420, and then the fixed end 810 can be processed at the first cold extrusion part 410.
[0071] Reference Figures 12 to 13 , in one embodiment, the plug-head dedicated terminal processing device further includes a punching device 430;
[0072] The second cold extrusion part 420 is used to process the raw material block into the connecting end 820, and the first cold extrusion part 410 is arranged at the post-process position of the second cold extrusion part 420;
[0073] The multi-axis robot device includes a first multi-axis robot part 510 and a second multi-axis robot part 520 , the second multi-axis robot part 520 is matched with the second cold extrusion part 420 , and the first multi-axis robot part 510 is matched with the first cold extrusion part 410 , the second cold extrusion part 420 and the punching device 430 .
[0074] In the conventional processing of the terminal outer shape 800, the preferred order is to first use the first cold extrusion part 410 to process the fixed end 810 on the raw material block, and then use the second cold extrusion part 420 to process the connection end 820. At this time, only a mold corresponding to the cylindrical shape of the connection end 820 needs to be set on the second cold extrusion part 420, and the mold structure at the first cold extrusion part 410 is relatively simple. It is found that due to the relatively complex structure of the connection end 820, the molding time of the first cold extrusion part 410 is shorter than the molding time at the first cold extrusion part 410 to a certain extent. In this embodiment, the processing sequence of the fixed end 810 and the connecting end 820 of the terminal shape part 800 is adjusted, the connecting end 820 is first processed on the raw material block using the second cold extrusion part 420, and then the fixed end 810 is processed using the first cold extrusion part 410, and the first multi-axis manipulator 510 takes out the terminal shape part 800 from the first cold extrusion part 410 and directly sends it to the punching device 430 for punching operation, so that the processing efficiency is optimized. The second multi-axis manipulator 520 is used to clamp the raw material block into the second cold extrusion part 420, the first multi-axis manipulator 510 is used to clamp the raw material block with the connecting end 820 out of the second cold extrusion part 420 and put it into the first cold extrusion part 410, clamp the terminal shape part 800 obtained by the first cold extrusion part 410 into the punching device 430 for punching operation, and clamp the terminal shape part 800 after the punching operation is completed out of the punching device 430.
[0075] In this embodiment, during a processing process, after the second multi-axis manipulator 520 takes the raw material block and puts it into the second cold extrusion part 420, the raw material block is extruded for 10 seconds in the second cold extrusion part 420; the first multi-axis manipulator 510 takes the raw material block processed into the connection terminal 820 from the second cold extrusion part 420, and puts it into the first cold extrusion part 410 for 5 seconds of extrusion; then the first multi-axis manipulator 510 has at least 5 seconds of time to take out the terminal shape part 800 from the first cold extrusion part 410 and put it into the punching device 430 for punching, take out the terminal shape part 800 after punching and place it in a predetermined position, and return to the second cold extrusion part 420 to wait for the raw material block processed into the connection terminal 820, thereby improving the processing efficiency of the plug-in terminal 900. Of course, in this embodiment, it is preferred that the first cold extrusion part 410 and the second cold extrusion part 420 are both provided with a mold corresponding to the cylindrical shape of the connection terminal 820 to ensure the molding effect of the terminal shape part 800.
[0076] Reference Figures 12 to 13 In one embodiment, the first multi-axis robot arm 510 is also matched with the first sample holding plate 310 .
[0077] That is, the cold extrusion device, the CNC machining center 100 and the first sample holding component 300 are designed in an associated manner to improve the use efficiency of the first multi-axis robot arm 510 and save the material transfer process.
[0078] A method for processing a special terminal for a plug head comprises the following steps:
[0079] The second multi-axis robot 520 is used to transfer the raw material block to the second cold extrusion unit 420 for processing, so as to complete the forming of the connecting terminal 820;
[0080] The first multi-axis robot 510 is used to clamp the raw material block processed to form the connecting end 820 and transfer it out of the second cold extrusion unit 420;
[0081] The first multi-axis manipulator 510 is used to clamp the raw material block processed to form the connecting end 820 and transfer it to the first cold extrusion unit 410 to complete the forming of the fixed end 810;
[0082] The first multi-axis robot 510 is used to transfer the raw material block from which the connecting end 820 and the fixing end 810 are processed into the punching device 430 to complete the terminal outer shape 800;
[0083] The first multi-axis manipulator 510 is used to transfer the terminal outer shape part 800 into the first sample holding plate 310;
[0084] The transfer assembly 200 is used to transfer the terminal outer shape member 800 on the first sample holding plate 310 into the CNC machining center 100;
[0085] The turning tool assembly 130 and the milling cutter assembly 140 are used to trim the terminal outer shape 800 to form a dedicated terminal 900 for a plug head.
[0086] The positions of the first cold extrusion unit 410, the second cold extrusion unit 420, the punching device 430 and the first sample holding assembly 300 are arranged in association, and materials are transferred between the above-mentioned devices through the first multi-axis manipulator 510. And because the time required for the second cold extrusion unit 420 to complete the processing is shorter than the time required for the first cold extrusion unit 410 to complete the processing, the time required for the first cold extrusion unit 410 and the punching device 430 to complete the processing is shorter, so the operation process of the first cold extrusion unit 410 and the punching device 430 is combined, so that the finishing efficiency of the terminal shape member 800 is optimized.
[0087] In one embodiment, the first multi-axis robot arm 510 is used to transfer the raw material block processed with the connecting end 820 and the fixed end 810 into the punching device 430 to complete the step of forming the terminal shape 800, and the first multi-axis robot arm 510 continues to clamp.
[0088] To sum up, the terminal processing device and method for plug-in heads provided by the present invention integrate the various steps of trimming into the CNC machining center 100, thereby achieving the effect of improving machining efficiency, and the structural complexity in the CNC machining center 100 increases slightly; at the same time, the CNC machining center 100 is matched with a transfer assembly 200, which improves the degree of automation of the terminal processing device for plug-in heads; the first double-jaw chuck 111 allows space for trimming the terminal outer shape 800 while clamping the terminal outer shape 800.
