Description

Technical Field

[0001] The invention relates to the technical field of wiring terminal processing, and in particular to an automatic flattening and trimming device for wiring terminals and a use method thereof. Background Art

[0002] The terminal block is a connecting component with a metal sheet as the main body and an insulating plastic sheet on the outside. It is mainly used for wire connection. The processing of the terminal block mainly includes punching, chamfering, flattening, trimming, etc. One end of the copper-aluminum terminal block is flat with a through hole, and the other end is cylindrical.

[0003] In the prior art, when processing copper-aluminum tubes into copper-aluminum noses or copper tubes into copper nose terminal blocks, materials are generally loaded by a robot clamp and finished products are unloaded by pneumatic blowing. However, when the robot clamps the materials for loading, the materials may be easily dropped due to loose clamping or damaged due to excessive clamping. Pneumatic blowing cannot effectively unify the blowing distance and blowing angle of each finished product after processing, making it easy for omissions to occur in the unloading work. At the same time, the flattening and trimming operations need to be completed on different devices. The flattening device loads and processes the materials, and then discharges them. The materials that have completed the flattening process need to be transferred to the trimming device for trimming and then discharged. The processing operation is cumbersome and the production and processing efficiency is also subject to certain limitations. Summary of the invention

[0017] Preferably, the lower cutting seat includes a lower cutting shell connected to the connecting plate, the lower cutting shell slides on the outside of the support platform and the flattening seat, a lower cutting knife is arranged on the bottom edge of the lower cutting shell, a stamping hole matching with the through hole is opened on the flattening seat, and a punch matching with the stamping hole is arranged on the lower side of the lower cutting shell.

[0020] The present invention also discloses a method for using the automatic flattening and trimming device for connecting terminals, comprising the following steps:

[0021] S1: placing a plurality of copper and aluminum tubes to be processed in a material box;

[0022] S2: Then the hydraulic cylinder is controlled to operate. When the hydraulic cylinder is in operation, the processing part is driven upward through the connecting plate, so that the processing part is away from the lower seat body on the upper side of the workbench. When the connecting plate moves upward, it drives the rack plate to move, and the rack plate is meshed with the one-way gear for transmission;

[0023] S3: The one-way gear drives the reciprocating screw to rotate. When the reciprocating screw rotates, the outer sleeve moves from the end close to the lower seat body to the end away from the lower seat body, and then the sleeve drives the push seat to move, so that the receiving groove of the push seat is opposite to the lower opening of the material box, and the copper and aluminum tube at the bottom of the material box automatically falls into the receiving groove;

[0024] As the rack plate continues to move upward, the sleeve moves to the end of the reciprocating screw rod away from the lower seat body and then moves back until the sleeve pushes the copper and aluminum tube in the receiving groove to the lower seat body through the pushing seat and passes over the support platform. At this time, the sleeve moves to the end of the reciprocating screw rod close to the lower seat body, and the staff makes the hydraulic cylinder no longer drive the processing part to move upward but moves the processing part downward. At this time, the meshing of the rack plate on the lower side of the connecting plate and the one-way gear will not drive the reciprocating screw rod to rotate;

[0025] S4: When the processing part moves downward with the connecting plate, the upper positioning seat of the processing part first abuts against the lower positioning seat, and the upper positioning seat and the lower positioning seat cooperate to position the copper and aluminum tubes to limit their lateral displacement during processing;

[0026] As the hydraulic cylinder drives the processing part to continue to move downward through the connecting plate, the second elastic telescopic rod is compressed, and the flattening seat of the processing part begins to contact the copper-aluminum tube in the positioning and cooperates with the support platform to flatten it. The part of the copper-aluminum tube that is flattened and extends to the outside of the support platform exerts a thrust on the extrusion slope on the side of the limit plate, so that the limit plate is forced to shrink into the movable groove;

[0027] As the hydraulic cylinder drives the processing part to continue to move downward through the connecting plate, the flattening seat cannot continue to move downward under the restriction of the support platform and the flattened copper-aluminum tube, the lower cutting shell on the outer side of the flattening seat moves downward, the first elastic telescopic rod is compressed, the lower cutting knife on the lower side of the lower cutting shell is opposite to the copper-aluminum tube part squeezed on the outer side of the flattening seat and cuts off, and the punch cooperates with the punching hole to punch the end of the flattened copper-aluminum tube, completing the automatic feeding processing of the copper-aluminum tube terminal;

[0028] S5: Repeat S2-S4. When the hydraulic cylinder is controlled to use the connecting plate to drive the processing part to move upward, the top of the limit plate on the connecting seat is no longer squeezed. The limit plate is pushed back and moved upward by the elastic force of the elastic element to limit the side edge of the flattened copper and aluminum tube end.

[0029] The pushing seat continues to push the copper-aluminum tube at the bottom of the material box. When the copper-aluminum tube to be processed is pushed, the copper-aluminum tube to be processed pushes the copper-aluminum tube terminal after processing, so that the copper-aluminum tube terminal moves axially along the lower seat body under the restriction of the limit plates on both sides of the connecting seat. In this process, one end of the copper-aluminum tube terminal hangs down on the material guide table under the action of gravity until the end of the copper-aluminum tube to be processed passes over the support table. At this time, the copper-aluminum tube terminal after processing automatically slides down along the material guide table.

[0030] Thereby realizing the continuous and automatic processing of multiple copper-aluminum tube terminal blocks.

[0031] Compared with the prior art, the present invention provides an automatic flattening and trimming device for terminal blocks and a method for using the same, which have the following beneficial effects:

[0032] 1. The automatic flattening and trimming device for the terminal block and the method for using the same can realize the flattening, punching and trimming of the copper-aluminum tube by controlling the hydraulic cylinder to drive the processing part to move downward, so that a single downward movement of the processing part can realize the flattening, punching and trimming of the copper-aluminum tube terminal block, simplify the processing process of the copper-aluminum tube terminal block, and improve the production and processing efficiency of the copper-aluminum tube terminal block.

[0033] 2. The automatic flattening and trimming device and the method for using the terminal block realize automatic pushing and loading of the copper and aluminum tubes by the pushing seat by controlling the hydraulic cylinder to drive the processing part to move upward, thereby avoiding the problems of slow manual loading speed and too tight or too loose clamping of the manipulator. After the hydraulic cylinder drives the processing part to move upward to release the pressing of the processed copper and aluminum tube terminal block, the pushing seat pushes the processed copper and aluminum tube terminal block when pushing and loading the copper and aluminum tube to be processed, so that the processed copper and aluminum tube terminal block is unloaded under the pushing action, thereby avoiding the inconsistent unloading position of the copper and aluminum tube terminal block caused by pneumatic blowing unloading, and the staff still needs to manually collect the finished products blown away to a distance, thereby reducing the workload of the staff and improving the processing efficiency of the terminal block.

[0034] 3. The automatic flattening and trimming device and use method of the terminal block can make the finished terminal block move horizontally under the push by setting limit plates on both sides of the connecting seat. During this process, one end of the copper-aluminum tube terminal block hangs down on the material guide table under the action of gravity, and then the copper-aluminum tube terminal block automatically slides down along the material guide table to realize the orderly collection of the finished terminal block.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0049] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0050] Example 1: Reference Figure 1 , Figure 3 , Figure 5 and Figure 6 , an automatic flattening and trimming device for terminal blocks, comprising a workbench 1, and further comprising:

[0053] The lower seat body 4 is fixed on the workbench 1 and is used to auxiliary support the copper and aluminum tubes 3. A material unloading auxiliary component is arranged on the outer side of the lower seat body 4;

[0054] A hydraulic cylinder 5, a support plate 102 is fixedly provided on the top of the workbench 1, and the hydraulic cylinder 5 is fixedly connected to the support plate 102;

[0055] The piston rod of the hydraulic cylinder 5 is connected to a connecting plate 501 , on which a processing portion 6 matching with the lower seat body 4 is arranged, and at the bottom of the connecting plate 501 a transmission portion for driving the loading assembly to work is arranged.

[0056] Specifically, a plurality of copper-aluminum tubes 3 to be processed are placed in the material box 2, and then the hydraulic cylinder 5 is controlled to operate. When the hydraulic cylinder 5 is in operation, the processing part 6 is driven to move upward through the connecting plate 501, so that the processing part 6 is away from the lower seat body 4 on the upper side of the workbench 1. During this process, the loading components work synchronously to realize automatic pushing and loading of the copper-aluminum tube 3, thereby avoiding the problems of slow manual loading speed and too tight or too loose clamping of the robot. When the hydraulic cylinder 5 drives the processing part 6 to move downward through the connecting plate 501, a single downward movement of the processing part 6 can realize the flattening, punching and trimming of the copper-aluminum tube 3, thereby simplifying the processing process of the copper-aluminum tube 3 terminal, and improving the production and processing efficiency of the copper-aluminum tube 3 terminal.

[0057] Example 2: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Fig. 9 and Fig.12 , an automatic flattening and trimming device for terminal blocks. On the basis of Example 1, further, the lower seat body 4 includes a lower positioning seat 401 fixed on the workbench 1 and a support platform 402 fixedly connected to the lower positioning seat 401, the lower positioning seat 401 is provided with a lower arc groove 4011 matching the copper-aluminum tube 3, and the support platform 402 is provided with a through hole 4021.

[0058] Furthermore, the loading assembly includes a support plate 7 fixed on the workbench 1, a reciprocating screw 701 rotatably connected to the support plate 7, a sleeve 702 threadedly connected to the reciprocating screw 701, and a pushing seat 703 connected to the sleeve 702 via a connecting rod, and a receiving groove 7031 for placing the copper-aluminum tube 3 is provided on the pushing seat 703.

[0059] Furthermore, the transmission part includes a rack plate 8 fixedly mounted on the lower side of the connecting plate 501 , and a one-way gear 9 meshing with the rack plate 8 is disposed on the reciprocating screw 701 .

[0060] Furthermore, the one-way gear 9 includes a driven wheel 901 fixedly connected to the reciprocating screw 701 and a driving wheel 902 rotatably connected to the driven wheel 901. A groove 9011 is provided on the driven wheel 901. A block 9012 movably abuts against the inner wall of the driving wheel 902 is rotatably connected in the groove 9011 through a pin shaft. A torsion spring is provided on the pin shaft for driving the block 9012 to reset and rotate. The inner wall of the driving wheel 902 is provided with slots 9021 evenly distributed in a circle and matched with the block 9012.

[0061] Specifically, the hydraulic cylinder 5 is controlled to operate. When the hydraulic cylinder 5 operates, the processing part 6 is driven to move upward through the connecting plate 501, so that the processing part 6 is away from the lower seat body 4 on the upper side of the workbench 1. When the connecting plate 501 moves upward, it drives the rack plate 8 to move, and the rack plate 8 is meshed with the one-way gear 9 for transmission.

[0062] The one-way gear 9 drives the reciprocating screw 701 to rotate. When the reciprocating screw 701 rotates, the outer sleeve 702 moves from the end close to the lower seat body 4 to the end away from the lower seat body 4, and then the sleeve 702 drives the push seat 703 to move, so that the receiving groove 7031 of the push seat 703 is opposite to the lower opening of the material box 2, and the copper-aluminum tube 3 at the bottom of the material box 2 automatically falls into the receiving groove 7031;

[0063] As the rack plate 8 continues to move upward, the sleeve 702 moves to the end of the reciprocating screw 701 away from the lower seat body 4 and then moves back, until the sleeve 702 pushes the copper-aluminum tube 3 in the receiving groove 7031 to the lower seat body 4 through the pushing seat 703 and passes over the support platform 402. At this time, the sleeve 702 moves to the end of the reciprocating screw 701 close to the lower seat body 4, and the staff makes the hydraulic cylinder 5 no longer drive the processing part 6 to move upward but makes the processing part 6 move downward. At this time, the meshing of the rack plate 8 on the lower side of the connecting plate 501 and the one-way gear 9 will not drive the reciprocating screw 701 to rotate;

[0064] The present application realizes automatic pushing and loading of the copper-aluminum tube 3 by the pushing seat 703 when controlling the processing part 6 to move upward, avoiding the problems of slow manual loading speed and too tight or too loose clamping of the robot, and after the hydraulic cylinder 5 drives the processing part 6 to move upward to release the suppression of the copper-aluminum tube 3 terminal after processing, the pushing seat 703 pushes the processed copper-aluminum tube 3 terminal when pushing and loading the copper-aluminum tube 3 to be processed, so that the processed copper-aluminum tube 3 terminal is unloaded under the pushing action, avoiding the inconsistent unloading position of the copper-aluminum tube 3 terminal caused by pneumatic blowing, and the falling position of the finished product is sometimes far and sometimes near, resulting in the staff still needing to manually collect the finished products blown to a distant place, reducing the workload of the staff and improving the processing efficiency of the terminal.

[0065] Example 3: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.12 , an automatic flattening and trimming device for a terminal block, based on Example 2, further, the processing part 6 includes a lower cutting seat 601 fixedly connected to the connecting plate 501, a first elastic telescopic rod 602 fixedly arranged on the lower side of the lower cutting seat 601, a flattening seat 603 connected to the end of the first elastic telescopic rod 602 away from the lower cutting seat 601, a second elastic telescopic rod 604 connected to the flattening seat 603, and an upper positioning seat 605 connected to the end of the second elastic telescopic rod 604 away from the flattening seat 603, the upper positioning seat 605 is provided with an upper arc groove 6051 matching the lower arc groove 4011, and the upper arc groove 6051 and the lower arc groove 4011 are enclosed to form a positioning groove for positioning the copper-aluminum tube 3.

[0066] Furthermore, the lower cutting seat 601 includes a lower cutting shell 6011 connected to the connecting plate 501, the lower cutting shell 6011 slides on the outside of the support platform 402 and the flattening seat 603, a lower cutting knife 6012 is arranged on the bottom edge of the lower cutting shell 6011, a stamping hole 6031 matching with the through hole 4021 is opened on the flattening seat 603, and a punch 6013 matching with the stamping hole 6031 is arranged on the lower side of the lower cutting shell 6011.

[0067] Furthermore, the support platform 402 has the same structure as the flattening seat 603 , the lower cutting knife 6012 cuts the copper-aluminum tube 3 extending out of the positioning groove and placed on the outside of the support platform 402 , and the punch 6013 punches the copper-aluminum tube 3 extending out of the positioning groove and placed between the support platform 402 and the flattening seat 603 .

[0068] Specifically, when the hydraulic cylinder 5 drives the processing part 6 to move downward through the connecting plate 501, the upper positioning seat 605 of the processing part 6 first abuts against the lower positioning seat 401, and the upper positioning seat 605 and the lower positioning seat 401 cooperate to position the copper-aluminum tube 3, limiting its lateral displacement during processing to avoid affecting the processing quality;

[0069] As the hydraulic cylinder 5 drives the processing part 6 to continue to move downward through the connecting plate 501, the second elastic telescopic rod 604 is compressed, and the flattening seat 603 of the processing part 6 begins to contact the copper-aluminum tube 3 in the positioning and cooperates with the support platform 402 to flatten it;

[0070] As the hydraulic cylinder 5 drives the processing part 6 to continue to move downward through the connecting plate 501, the flattening seat 603 cannot continue to move downward under the restriction of the support platform 402 and the flattened copper-aluminum tube 3, and the lower cut shell 6011 on the outer side of the flattening seat 603 moves downward, the first elastic telescopic rod 602 is compressed, and the lower cutter 6012 on the lower side of the lower cut shell 6011 is located on the outer side of the flattening seat 603 and cuts off the part of the copper-aluminum tube 3 that is squeezed, and the punch 6013 cooperates with the punching hole 6031 to punch the end of the flattened copper-aluminum tube 3, completing the automatic feeding processing of the copper-aluminum tube 3 terminal;

[0071] The present application controls the hydraulic cylinder 5 to drive the processing part 6 to move downward, so that a single downward movement of the processing part 6 can realize the flattening, punching and trimming of the copper-aluminum tube 3, thereby solving the problem of using different processing equipment to flatten, punch and trim the raw materials in sequence in the prior art, simplifying the processing process of the copper-aluminum tube 3 terminal, and improving the production and processing efficiency of the copper-aluminum tube 3 terminal.

[0072] Example 4: Reference Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 , an automatic flattening and trimming device for terminal blocks, based on Example 3, further, a material unloading auxiliary component includes a connecting seat 10 fixedly arranged on the outside of a support platform 402, a movable groove 1001 is provided on the side where the connecting seat 10 is in contact with the support platform 402, a limiting plate 1002 is slidably connected in the movable groove 1001, an elastic element 1003 is provided between the limiting plate 1002 and the movable groove 1001, an extrusion slope is provided on the side of the limiting plate 1002 close to the support platform 402, a workbench 1 is placed on the lower side of the support platform 402 and a waste groove 103 is provided, and a material guide platform 104 is fixed on the end of the workbench 1 away from the feeding component.

[0073] Specifically, when the hydraulic cylinder 5 drives the processing part 6 to move downward through the connecting plate 501, the flattening seat 603 contacts the copper-aluminum tube 3 in the positioning and cooperates with the support platform 402 to flatten it. The part of the copper-aluminum tube 3 that is flattened and extends to the outside of the support platform 402 applies a thrust to the extrusion slope on the side of the limit plate 1002, so that the limit plate 1002 is forced to shrink into the movable groove 1001. After the copper-aluminum tube 3 is processed into a wiring terminal, the hydraulic cylinder 5 is controlled to use the connecting plate 501 to drive the processing part 6 to move upward, and the top of the limit plate 1002 on the connecting seat 10 is no longer squeezed. The limit plate 1002 is reset to the upper position under the elastic force of the elastic element 1003. The pushing seat 703 continues to push the copper-aluminum tube 3 at the bottom in the material box 2. When the copper-aluminum tube 3 to be processed is pushed, the copper-aluminum tube 3 to be processed pushes the processed copper-aluminum tube 3 terminal, so that the copper-aluminum tube 3 terminal moves axially along the lower seat body 4 under the restriction of the limit plates 1002 on both sides of the connecting seat 10, so that the processed finished terminal moves horizontally under the pushing. In this process, one end of the copper-aluminum tube 3 terminal hangs on the material guide table 104 under the action of gravity, and then the copper-aluminum tube 3 terminal automatically slides down along the material guide table 104, so as to realize the orderly collection of the finished terminal.

[0074] The present invention also discloses a method for using the automatic flattening and trimming device for connecting terminals, comprising the following steps:

[0075] S1: placing a plurality of copper and aluminum tubes 3 to be processed in a material box 2;

[0076] S2: Then the hydraulic cylinder 5 is controlled to operate. When the hydraulic cylinder 5 operates, the processing part 6 is driven to move upward through the connecting plate 501, so that the processing part 6 is away from the lower seat body 4 on the upper side of the workbench 1. When the connecting plate 501 moves upward, it drives the rack plate 8 to move, and the rack plate 8 is meshed with the one-way gear 9 for transmission;

[0077] S3: The one-way gear 9 drives the reciprocating screw 701 to rotate. When the reciprocating screw 701 rotates, the outer sleeve 702 moves from the end close to the lower seat body 4 to the end away from the lower seat body 4, and then the sleeve 702 drives the push seat 703 to move, so that the receiving groove 7031 of the push seat 703 is opposite to the lower opening of the material box 2, and the copper-aluminum tube 3 at the bottom of the material box 2 automatically falls into the receiving groove 7031;

[0078] As the rack plate 8 continues to move upward, the sleeve 702 moves to the end of the reciprocating screw 701 away from the lower seat body 4 and then moves back, until the sleeve 702 pushes the copper-aluminum tube 3 in the receiving groove 7031 to the lower seat body 4 through the pushing seat 703 and passes over the support platform 402. At this time, the sleeve 702 moves to the end of the reciprocating screw 701 close to the lower seat body 4, and the staff makes the hydraulic cylinder 5 no longer drive the processing part 6 to move upward but makes the processing part 6 move downward. At this time, the meshing of the rack plate 8 on the lower side of the connecting plate 501 and the one-way gear 9 will not drive the reciprocating screw 701 to rotate;

[0079] S4: When the processing part 6 moves downward with the connecting plate 501, the upper positioning seat 605 of the processing part 6 first abuts against the lower positioning seat 401, and the upper positioning seat 605 and the lower positioning seat 401 cooperate to position the copper-aluminum tube 3 to limit its lateral displacement during processing;

[0080] As the hydraulic cylinder 5 drives the processing part 6 to continue to move downward through the connecting plate 501, the second elastic telescopic rod 604 is compressed, and the flattening seat 603 of the processing part 6 begins to contact the copper-aluminum tube 3 in the positioning and cooperates with the support platform 402 to flatten it. The flattened portion of the copper-aluminum tube 3 extending to the outside of the support platform 402 applies a thrust to the extrusion slope on the side of the limit plate 1002, so that the limit plate 1002 is forced to shrink into the movable groove 1001;

[0081] As the hydraulic cylinder 5 drives the processing part 6 to continue to move downward through the connecting plate 501, the flattening seat 603 cannot continue to move downward under the restriction of the support platform 402 and the flattened copper-aluminum tube 3, and the lower cut shell 6011 on the outer side of the flattening seat 603 moves downward, the first elastic telescopic rod 602 is compressed, and the lower cutter 6012 on the lower side of the lower cut shell 6011 is located on the outer side of the flattening seat 603 and cuts off the part of the copper-aluminum tube 3 that is squeezed, and the punch 6013 cooperates with the punching hole 6031 to punch the end of the flattened copper-aluminum tube 3, completing the automatic feeding processing of the copper-aluminum tube 3 terminal;

[0082] S5: Repeat S2-S4. When the hydraulic cylinder 5 is controlled to drive the processing part 6 to move upward by using the connecting plate 501, the top of the limiting plate 1002 on the connecting seat 10 is no longer squeezed. The limiting plate 1002 is pushed back and moved upward by the elastic force of the elastic element 1003, so as to limit the side edge of the end of the flattened copper-aluminum tube 3.

[0083] The pushing seat 703 continues to push the copper-aluminum tube 3 at the bottom of the material box 2. When the copper-aluminum tube 3 to be processed is pushed, the copper-aluminum tube 3 to be processed pushes the copper-aluminum tube 3 terminal after processing, so that the copper-aluminum tube 3 terminal moves axially along the lower seat body 4 under the restriction of the limit plates 1002 on both sides of the connecting seat 10. In this process, one end of the copper-aluminum tube 3 terminal hangs down on the material guide table 104 under the action of gravity until the end of the copper-aluminum tube 3 to be processed passes over the support table 402. At this time, the copper-aluminum tube 3 terminal after processing automatically slides down along the material guide table 104.

[0084] Thereby, continuous and automated processing of multiple copper-aluminum tube 3 connection terminals is realized.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
