Description

Technical Field

[0001] The present invention relates to the technical field of automatic cutting, in particular to a wiring terminal spacing cutting machine and a cutting method thereof. Background Art

[0002] Existing terminal products are made of metal sheets through stamping. Figure 1 As shown; the terminal strip is in the shape of a long strip, and a terminal strip contains a plurality of terminal blocks 1 connected in sequence, with a separation gap 3 between adjacent terminal blocks, so that a certain distance is separated between two adjacent terminal blocks; adjacent terminal blocks are connected by connecting ribs 2.

[0003] Among them, after the terminal blocks are produced, they are shipped to customers in the form of a whole piece. When the customer uses them, he needs to cut off the terminal blocks 1 one by one.

[0004] Conventional terminal blocks are cut manually one by one. During cutting, the operator uses ordinary scissors to cut the connecting rib 2 connecting the two terminal blocks, thereby cutting the terminal blocks one by one. This purely manual operation has the problems of low cutting efficiency and high labor costs. In addition, due to the inconsistent operating proficiency of different operators during the operation, the shape of the cut on the terminal block varies from person to person, and the cut shape is inconsistent, making it difficult to ensure cutting quality.

[0014] A fixing rod is provided at the upper end of the sliding block, and a bayonet calibration block is provided at the upper end of the fixing rod. The two opposite side surfaces of the bayonet calibration block in one direction are both contact arc surfaces. The maximum width between the two contact arc surfaces is the calibration width, and the calibration width is the same as the width of the separation gap between adjacent wiring terminals; the width distance between the two opposite side surfaces in the other direction of the bayonet calibration block is less than the width of the separation gap between adjacent wiring terminals.

[0015] The installation cylinder is provided with a lifting drive member for driving the bayonet calibration block to lift and lower, and the lifting drive member is rotationally connected to the sliding block;

[0016] When the lifting drive drives the bayonet calibration block to rise, the bayonet calibration block passes through the separation gap between adjacent wiring terminals from bottom to top; when the upper end of the bayonet calibration block is higher than the wiring terminal, the convex shaft enters the rotating bevel groove, and the convex shaft drives the sliding block to rotate when sliding in the rotating bevel groove.

[0017] Preferably, the adjustment device includes a guide rail arranged on the frame, a sliding seat is slidably connected to the guide rail, and fixed blocks are respectively provided on both sides of the sliding seat; screw mounting seats corresponding to the fixed blocks are respectively provided on both sides of the guide rail, an adjusting screw is threadedly connected to the screw mounting seat, and the front end of the adjusting screw is connected to the fixed block.

[0018] Preferably, the guide rail is arranged along the length direction of the material guiding component.

[0019] A method for cutting a terminal block at a predetermined distance comprises the following specific steps:

[0020] Pass one end of the terminal strip to be cut through the guide slot on the guide component, and manually adjust the position of the terminal strip so that the cutting unit cuts exactly in the middle of two adjacent terminal strips;

[0021] After starting the terminal spacing cutting machine, the clamping device first clamps the terminal strip, and then the feeding cylinder drives the clamping device to move forward, pushing the terminal strip forward through the clamping device. The distance the clamping device moves forward each time is the same as the center distance between two adjacent terminal blocks.

[0022] After the clamping device pushes the terminal strip, the shearing unit performs a shearing action to cut off the terminal at the end of the terminal strip;

[0023] After the shearing is completed, the clamping device first releases the terminal strip, and then the feeding cylinder drives the clamping device to move to the initial position. Then the clamping device clamps the terminal strip again and pushes the terminal strip forward through the clamping device. Then the shearing device shears the terminal strip again.

[0027] When positioning and calibrating the terminal strip, the clamping device is in a state of releasing the terminal strip, and the lifting drive drives the bayonet calibration block to rise, so that the bayonet calibration block passes through the separation gap between adjacent terminal blocks from bottom to top; when the upper end of the bayonet calibration block is higher than the terminal, the convex shaft enters the rotating inclined groove from the rising straight groove, and the convex shaft drives the sliding block to rotate when sliding in the rotating inclined groove; when the bayonet calibration block rises to the set height, the rotation angle of the bayonet calibration block is 90 degrees. At this time, the calibration width direction of the bayonet calibration block is consistent with the length direction of the terminal strip and is in a second angle state, and the contact arc surfaces on both sides of the bayonet calibration block are in contact with the terminal blocks on both sides thereof;

[0028] During the rotation of the bayonet calibration block, the bayonet calibration block applies a pushing force in the length direction to the terminal strip and causes the terminal strip to move, thereby achieving positioning calibration of the terminal strip;

[0029] After the positioning calibration is completed, the lifting drive drives the bayonet calibration block to descend to the initial position, and then continues to cut the terminal strip.

[0030] The beneficial effects of the present invention are:

[0031] 1. The present invention can realize automatic continuous cutting of terminal strips, which has the advantages of saving time and labor, and greatly improves work efficiency; and the present invention adopts a mechanized method for shearing.

[0049] like Figure 2-12 As shown, a terminal block spacing cutting machine includes a frame 4, on which are mounted a control device 9, a shearing unit, a feeding unit, a guide member 5 for guiding the terminal strips, and a positioning and calibration device. The control device 9 is a programmable logic controller (PLC) that controls the operation of the shearing unit, feeding unit, and positioning and calibration device.

[0050] The guide member 5 is provided with a guide groove 21 that passes through both ends of the guide member 5 and a clamping notch 22. The terminal strip passes through the guide groove 21. The terminal strip 1 located on the clamping notch 22 is partially located outside the guide member 5.

[0051] The feeding unit includes a feeding propulsion cylinder 6, to which an adapter frame 7 is connected. The adapter frame 7 is provided with a clamping device 8 for clamping the terminal strip. The feeding unit is used to clamp the terminal strip and push the terminal strip toward the shearing unit. The feeding propulsion cylinder 6 is used to push the adapter frame 7 and the clamping device 8 provided on the adapter frame 7 back and forth in the horizontal direction. The adapter frame 7 is connected to the piston rod on the feeding propulsion cylinder 6. In the present invention, the clamping device 8 is a cylinder clamp, which is provided with two claws for clamping the terminal.

[0052] The shearing unit includes a fixed shearing part 13 and a movable shearing part 14 that can rotate relative to the fixed shearing part 13, and the movable shearing part 14 is connected to the shearing drive mechanism. Among them, a fixed plate 11 is provided on the frame 4, and the fixed shearing part 13 is arranged on the fixed plate 11. The movable shearing part 14 is rotatably connected to the fixed plate 11 through a hinge shaft 24. The hinge shaft 24 is fixed to the fixed plate 11, and the movable shearing part 14 can rotate around the hinge shaft 24. The shearing drive mechanism includes a shearing drive member 10, and the shearing drive member 10 is connected to a bracket 12, and the bracket 12 is provided with a sliding shaft 20; one end of the movable shearing part 14 is provided with a slide groove 19, and the sliding shaft 20 is connected to the slide groove 19, and the sliding shaft 20 can slide in the slide groove 19. In the present invention, the shearing drive member 10 is a vertically arranged cylinder or hydraulic cylinder, which is provided with a piston rod, and the bracket 12 is connected to the piston rod. The shear drive 10 drives the bracket 12 up and down, thereby driving the movable shearing section 14 to rotate, thereby achieving relative rotation between the movable shearing section 14 and the fixed shearing section 13, thereby achieving the shearing action. Both the movable shearing section 14 and the fixed shearing section 13 are equipped with shearing blades; when shearing a terminal strip, the terminal strip is located between the movable shearing section 14 and the fixed shearing section 13, and the rotation of the movable shearing section 14 achieves the cutting of the terminal strip.

[0053] The positioning and calibration device is used to position and calibrate the terminal strip. The positioning and calibration device includes a movable adjustment device and a mounting cylinder 15, and the mounting cylinder 15 is arranged on the movable adjustment device. Among them, the adjustment device includes a guide rail 17 arranged on the frame 4, and the guide rail 17 is arranged along the length direction of the material guide component 5. The guide rail 17 is located below the clamping notch 22 on the material guide component 5. A sliding seat 18 is slidably connected to the guide rail 17, and fixed blocks 27 are respectively provided on both sides of the sliding seat 18; screw mounting seats 26 corresponding to the fixed blocks 27 are respectively provided on both sides of the guide rail 17, and an adjusting screw 28 is threadedly connected to the screw mounting seat 26, and the front end of the adjusting screw 28 is connected to the fixed block 27. By adjusting the two adjusting screws 28, the position of the sliding seat 18 can be adjusted.

[0054] The upper end of the mounting cylinder 15 is provided with a guide cylinder 16, which is provided with a guide hole 35. The guide hole 35 is arranged in the vertical direction and has a circular cross-section. A sliding block 31 is slidably connected to the guide hole 35. The sliding block 31 has a cylindrical structure and can slide along the guide hole 35 and can also rotate within a certain angle range. A protruding shaft is provided on the side of the sliding block 31. The inner wall of the guide hole 35 is provided with a constraint groove, which includes an ascending straight groove 32 and a rotating bevel groove 33. The ascending straight groove 32 is arranged along the axial direction of the guide hole 35, and the lower end of the rotating bevel groove 33 is connected to the upper end of the ascending straight groove 32; the rotating bevel groove 33 is in a spiral ascending state, and the protruding shaft extends into the constraint groove and can slide within the constraint groove.

[0055] The upper end of the sliding block 31 is provided with a fixing rod 25, and the upper end of the fixing rod 25 is provided with a bayonet calibration block 23. Two opposing side surfaces of the bayonet calibration block 23 in one direction are contact arcs 36. The maximum width between the two contact arcs 36 is the calibration width, which is the same as the width of the gap 3 separating adjacent terminal blocks. The contact arcs 36 are circular arcs with a radius of curvature that is 1 / 2 of the calibration width. The width between the two opposing side surfaces of the bayonet calibration block 23 in the other direction is less than the width of the gap 3 separating adjacent terminal blocks.

[0056] A lifting drive member 30 is provided in the mounting tube 15 for driving the bayonet calibration block 23 to rise and fall. The lifting drive member 30 is rotatably connected to the sliding block 31. In the present invention, the lifting drive member 30 is an electric push rod, which is provided with a lifting rod. The upper end of the lifting rod is rotatably connected to the lower end of the sliding block 31, and the sliding block 31 can rotate relative to the lifting rod.

[0057] When the lifting drive 30 drives the bayonet calibration block 23 to rise, the bayonet calibration block 23 passes through the separation gap 3 between adjacent terminal blocks from bottom to top; when the upper end of the bayonet calibration block 23 is higher than the terminal block, the convex shaft enters the rotating bevel 33, and the convex shaft drives the sliding block 31 to rotate when sliding in the rotating bevel 33.

[0058] A method for cutting a terminal block at a predetermined distance comprises the following specific steps:

[0059] Pass one end of the terminal strip to be cut through the guide slot 21 on the guide member 5, and manually adjust the position of the terminal strip so that the cutting unit cuts exactly in the middle of two adjacent terminals;

[0060] After starting the terminal spacing cutting machine, the clamping device 8 first clamps the terminal strip, and then the feeding cylinder 6 drives the clamping device 8 to move forward, pushing the terminal strip forward through the clamping device 8. The distance the clamping device 8 moves forward each time is the same as the center distance between two adjacent terminal blocks.

[0061] After the clamping device 8 pushes the terminal strip, the shearing unit performs a shearing action to cut off the terminal at the end of the terminal strip;

[0062] After the shearing is completed, the clamping device 8 first releases the terminal strip, and then the feeding cylinder 6 drives the clamping device 8 to move to the initial position, and then the clamping device 8 clamps the terminal strip again and pushes the terminal strip forward through the clamping device 8, and then the shearing device shears the terminal strip again;

[0063] The above process is repeated to continuously cut the terminal strips; when the required number of cuts is reached, the terminal spacing cutting machine is turned off.

[0064] In actual use, during the continuous cutting of the terminal strip, there will be a slight error in the pushing distance of the terminal strip by the feeding push cylinder 6 each time. In the process of continuous and repeated pushing, the error will accumulate to form a cumulative error, which will cause a large deviation between the actual axial position of the terminal strip and the theoretical position. This will cause the shearing unit to shear the terminal. The cutting position is not in the middle of the two adjacent terminals, resulting in inaccurate cutting position; once the cumulative error is too large, the cutting position will fall directly on the terminal body, which will directly damage the terminal.

[0065] Therefore, in order to solve the above problems, during the continuous cutting of the terminal strip, the position of the terminal strip is calibrated by a positioning calibration device after each set number of cuts; the positioning calibration device will position and calibrate the terminal strip at a certain number of intervals to regularly eliminate the accumulated errors during the movement of the terminal.

[0066] Among them, the specific calibration method of the positioning calibration device is as follows:

[0067] Before the positioning and calibration device performs positioning and calibration on the terminal strip, the calibration width direction on the bayonet calibration block 23 is perpendicular to the length direction of the terminal strip, and the bayonet calibration block is at a first angle state;

[0068] When positioning and calibrating the terminal strip, the clamping device 8 is in a state of releasing the terminal strip, and the lifting drive 30 drives the bayonet calibration block to rise, so that the bayonet calibration block 23 passes through the separation gap 3 between adjacent terminal blocks from bottom to top; when the upper end of the bayonet calibration block 23 is higher than the terminal, the convex shaft enters the rotating inclined groove 33 from the rising straight groove 32, and the convex shaft drives the sliding block 31 to rotate when sliding in the rotating inclined groove 33; when the bayonet calibration block 23 rises to the set height, the rotation angle of the bayonet calibration block 23 is 90 degrees. At this time, the calibration width direction of the bayonet calibration block 23 is consistent with the length direction of the terminal strip and is in a second angle state, and the contact arc surfaces 36 on both sides of the bayonet calibration block 23 are in contact with the terminal blocks on both sides thereof;

[0069] During the rotation of the bayonet calibration block 23, the bayonet calibration block 23 applies a pushing force in the length direction to the terminal strip and prompts the terminal strip to move, thereby achieving positioning calibration of the terminal strip;

[0070] After the positioning and calibration are completed, the lifting drive member 30 drives the bayonet calibration block 23 to descend to the initial position, and then continues to cut the terminal strip.

[0071] Among them, before the positioning and calibration device performs positioning and calibration on the terminal strip, it is necessary to adjust the position of the bayonet calibration block 23 by moving the adjustment device; when the position adjustment of the bayonet calibration block 23 is completed, the following conditions need to be met: when the bayonet calibration block 23 rises to the second angle state, the bayonet calibration block 23 is just stuck in the partition gap 3 between two adjacent terminals, and at this time the cutting position of the shearing unit on the terminal strip is just located in the middle position of two adjacent terminals on the terminal strip.

[0072] The present invention has the following advantages:

[0073] 1. The present invention can realize automatic continuous cutting of terminal strips, which has the advantages of saving time and labor, and greatly improves work efficiency; and the present invention adopts a mechanized method for shearing. Compared with traditional manual shearing, the shape of the cut can maintain a high consistency and the cutting quality is more stable.

[0074] 2. The present invention is provided with a positioning calibration device, which can regularly eliminate the accumulated error when the terminal strip is moved, thereby improving the cutting accuracy of the terminal strip.

[0075] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that is the same or similar to that of the present application falls within the scope of protection of the present invention.
