[0002] The terminal block is an accessory product used to achieve electrical connection and is a type of connector. The existing terminal block production requires the use of stamping equipment to punch copper, aluminum, copper alloy, and copper-aluminum alloy into conductive sheets of the required shape and size, and then punch the conductive sheets into a ring structure to facilitate connection with the wire.

[0046] When batch forming is performed for the terminal blocks, the strip-shaped conductive sheet for preparing the terminal blocks can be placed on the upper part of the base plate 10, and then the conveying assembly 20 is used to convey the strip-shaped conductive sheet to the direction of the curling assembly 60 for a predetermined distance, and then the second driving assembly 80 drives the curling assembly 60 to rotate, so as to curl one end of the strip-shaped conductive sheet into a ring structure, and then the first driving assembly 40 drives the cutter 50 to move downward, and the cutter 50 cuts off the conductive sheet of the ring structure, so that the conductive sheet of the ring structure is separated from the subsequent strip-shaped conductive sheet, and then the pushing assembly 70 pushes the conductive sheet of the ring structure from the One end of the curling component 60 is pushed away, and then the conveying component 20 conveys the strip conductive sheet to the curling component 60 for a predetermined distance again, and the second driving component 80 drives the curling component 60 to rotate again to curl one end of the strip conductive sheet into a ring structure again, and then the first driving component 40 drives the cutter 50 to move downward again, and then the conductive sheet with the ring structure is cut again, and the pushing component 70 pushes the cut conductive sheet with the ring structure away from one end of the curling component 60 again, and this reciprocating cycle can continuously form a longer strip conductive sheet into a number of conductive sheets with ring structures.

[0048] After the second driving assembly 80 drives the curling assembly 60 to rotate and thus winds one end of the strip-shaped conductive sheet into a ring-shaped structure, the hydraulic cylinder 401 drives the lifting rod 402 to move downward, and the lifting rod 402 drives the cutter 50 to move downward. The cutter 50 acts on the strip-shaped conductive sheet and then cuts the conductive sheet with a ring-shaped structure.

[0049] See also Figure 1 , Figure 3 as well as Figure 4 In one embodiment, the winding assembly 60 includes a reel 601, a reel rod 603 and a support 605, one end of the reel 601 is fixedly provided with a rotating shaft 606, one end of the rotating shaft 606 away from the reel 601 passes through the third bracket plate 103 and rotatably cooperates with the third bracket plate 103, the support 605 is fixedly provided on the side wall of the reel 601, one end of the reel rod 603 is rotatably connected to the support 605, and the other end extends along the length direction of the reel 601, the reel rod 603 is distributed parallel to the reel 601, the second drive 80 includes a support rod 801, a rack rod 802 and a second gear 803, the second gear 803 is fixedly provided on the outside of the rotating shaft 606, one end of the support rod 801 is fixedly connected to the cutter 50, and the other end is fixedly connected to the rack rod 802, the rack rod 802 is vertically distributed, and the rack rod 802 is meshed with the second gear 803.

[0050] The strip conductive sheet is conveyed to a predetermined distance between the reel 601 and the reel rod 603 by the conveying assembly 20, and then the hydraulic rod 401 drives the lifting rod 402 to move downward, thereby driving the cutter 50 to move downward. When the cutter 50 moves downward, the support rod 801 drives the rack rod 802 to move downward, and the meshing action of the rack rod 802 and the second gear 803 drives the rotating shaft 606 to rotate. When the rotating shaft 606 rotates, it drives the reel 601 and the reel rod 603 to rotate. When the reel rod 603 rotates, it acts on one end of the strip conductive sheet, thereby driving the strip conductive sheet to bend and wrap around the reel. 601, thereby forming a conductive sheet with an annular structure. When one end of the strip conductive sheet rotates around the reel 601 for one circle, the cutter 50 moves down and acts on the strip conductive sheet, thereby cutting the conductive sheet with an annular structure. After the conductive sheet with an annular structure is cut, the hydraulic cylinder 401 drives the lifting rod 402 to move upward, thereby driving the cutter 50 and the rack rod 802 to move upward. When the rack rod 802 moves upward, it drives the rotating shaft 606 to rotate in the opposite direction through the reverse meshing action with the second gear 803, thereby driving the reel 601 and the reel rod 603 to rotate in the opposite direction.

[0052] After the conductive sheet of the annular structure is cut off, the hydraulic cylinder 401 drives the lifting rod 402 to move up, thereby driving the reel 601 and the reel 603 to rotate in the opposite direction. At this time, the power mechanism drives the first gear 701 to rotate forward, thereby driving the reel 603 to rotate forward compared to the support 605. The threaded section 604 on the outside of the reel 603 cooperates with the sleeve 702 to drive the sleeve 702 to move along the length direction of the reel 603. The sleeve 702 drives the push rod 703 to slide along the inside of the slot 602, thereby moving the annular structure sleeved on the outside of the reel 601. The conductive sheet of the structure is pushed away from one end of the reel 601. After the conductive sheet of the ring structure is pushed away from one end of the reel 601, the power mechanism drives the first gear 701 to rotate in the opposite direction, thereby driving the reel 603 to rotate in the opposite direction compared to the support 605. At this time, the reverse thread cooperation between the threaded section 604 and the sleeve 702 drives the sleeve 702 to slide in the opposite direction along the length direction of the reel 603, and the sleeve 702 drives the push rod 703 to slide in the opposite direction along the inside of the slot 602, thereby realizing the resetting of the push rod 703, so as to push away the conductive sheet of the ring structure that is subsequently sleeved on the outside of the reel 601 again.

[0054] When the hydraulic cylinder 401 drives the lifting rod 402 to move downward and then drives the reel 601 and the reel 602 to rotate, the first gear 701 rotates along the inner side of the second arc plate 1034, thereby acting on the plurality of second oblique tooth pieces 1035 and driving the plurality of second oblique tooth pieces 1035 to deflect in sequence toward the second arc plate 1034, and the plurality of second oblique tooth pieces 1035 cannot mesh with the first gear 701, and the reel 603 cannot rotate relative to the support 605, thereby failing to drive the push rod 703 to slide along the inside of the notch 602. After the conductive sheet of the annular structure is cut off, the hydraulic cylinder 40 1 drives the lifting rod 402 to move upward, thereby driving the reel 601 and the reel 603 to rotate in the opposite direction. At this time, the first gear 701 acts on the plurality of second oblique tooth pieces 1035 in the opposite direction and enters into a meshing state with the plurality of second oblique tooth pieces 1035. The first gear 701 drives the reel 603 to rotate relative to the support 605, thereby driving the push rod 703 to slide along the inside of the notch 602 through the threaded cooperation between the threaded section 604 and the threaded sleeve 702, so as to push the conductive sheet of the annular structure sleeved on the outside of the reel 601 away from one end of the reel 601, thereby realizing automatic unloading of the conductive sheet of the annular structure.

[0056] When the hydraulic cylinder 401 drives the lifting rod 402 to move downward and then drives the reel 601 and the reel 602 to rotate, the first gear 701 rotates along the outer side of the first arc plate 1031, thereby acting on the first oblique tooth pieces 1032 and driving the first oblique tooth pieces 1032 to deflect in sequence toward the first arc plate 1031, and the first oblique tooth pieces 1032 cannot mesh with the first gear 701, and the reel 603 cannot rotate relative to the support 605. When the push rod 703 moves the conductive ring structure After the sheet is pushed away from one end of the reel 601, as the reel 601 and the reel rod 603 continue to rotate in the opposite direction, the first gear 701 can act on the plurality of first beveled tooth sheets 1032 and enter into a meshing state with the plurality of first beveled tooth sheets 1032, and the first gear 701 drives the reel rod 603 to rotate in the opposite direction compared to the support 605, and then drives the push rod 703 to slide in the opposite direction along the inside of the slot 602 through the reverse thread cooperation of the threaded section 604 and the sliding sleeve 702, thereby realizing the resetting of the push rod 703.

[0057] See also Figure 1 In one embodiment, the conveying assembly 20 includes a motor 201 and conveying rollers 202. The conveying rollers 202 are provided with two groups. The two groups of conveying rollers 202 are rotatably installed on one side of the first bracket plate 101 and are distributed in an upper and lower interval. The motor 201 is fixedly installed on the side wall of the first bracket plate 101, and is used to drive the two groups of conveying rollers 202 to rotate relative to each other.

[0058] The motor 201 drives the two sets of conveying rollers 202 to rotate relative to each other, and the friction of the two sets of conveying rollers 202 on the strip conductive sheet is used to convey the strip conductive sheet between the reel 601 and the reel rod 603. The hydraulic cylinder 401 drives the cutter 50 to move up and down and the reciprocating rotation of the reel 601 and the reel rod 603 to achieve continuous forming of the strip conductive sheet.

[0059] See also Figure 1 In one embodiment, a limiting assembly 30 is further provided at one end of the lifting rod 402 away from the cutter 50. When the hydraulic cylinder 401 drives the lifting rod 402 to move downward, and then drives the reel 601 and the reel 603 to rotate through the meshing action of the rack rod 802 and the second gear 803, the limiting assembly 30 is used to limit the strip conductive sheet, thereby ensuring that the reel 603 can stably wind one end of the strip conductive sheet around the outside of the reel 601 to improve the molding effect.

[0060] See also Figure 1In one embodiment, the limiting assembly 30 includes a pressure plate 301, a third elastic member 302 and a pressure rod 303. The pressure rod 303 vertically penetrates the lifting rod 402 and movably cooperates with the lifting rod 402. The pressure plate 301 is fixedly installed at the bottom of the pressure rod 303. One end of the third elastic member 302 is connected to the pressure plate 301, and the other end is connected to the lifting rod 402, so as to provide elastic support for the pressure plate 301.

[0061] When the hydraulic cylinder 401 drives the lifting rod 402 to move downward and then drives the cutter 50 to move downward, the lifting rod 402 drives the pressure plate 301 to move downward through the third elastic member 302, and the pressure plate 301 acts on the strip-shaped conductive sheet and then presses the strip-shaped conductive sheet. After the strip-shaped conductive sheet is pressed, the rack rod 802 engages with the second gear 803, and then drives the reel 601 and the reel 603 to rotate. When the reel 603 rotates, since the strip-shaped conductive sheet is in a pressed state, the reel 603 can stably wind one end of the strip-shaped conductive rod to the outside of the reel 601, thereby forming a conductive sheet with a ring structure. After the pressure plate 301 presses the strip-shaped conductive sheet, the two sets of conveying rollers 202 slide compared to the strip-shaped conductive sheet. Then the conveying of the strip conductive sheet is stopped; after the hydraulic cylinder 401 drives the lifting rod 402 and the cutter 50 to move upward and the rack rod 802 and the second gear 803 drive the reel 601 and the reel 603 to rotate in the opposite direction to the initial position, the lifting rod 402 pulls the pressure plate 301 through the third elastic member 302 to move the pressure plate 301 upward, and the pressure plate 301 is separated from the strip conductive sheet to release the clamping state of the strip conductive sheet. At this time, the two sets of conveying rollers 202 continue to convey the strip conductive sheet until the strip conductive sheet moves a predetermined distance from between the reel 601 and the reel 603 again, and the hydraulic cylinder 401 drives the lifting rod 402 to move downward again, and then one end of the strip conductive sheet is curled again.

[0062] See also Figure 1 In one embodiment, a support plate 104 is fixedly provided on the upper portion of the base plate 10 below the pressing plate 301 .

[0063] When the hydraulic cylinder 401 drives the lifting rod 402 to move downward and then drives the pressing plate 301 to move downward, the pressing plate 301 can press the strip conductive sheet against the upper part of the support plate 104. Through the cooperation between the pressing plate 301 and the support plate 104, the pressing effect of the strip conductive sheet can be improved.

[0064] In one embodiment, the first elastic member 1033 , the second elastic member 1036 and the third elastic member 302 may be springs or metal springs, which are not limited here.

[0065] In the embodiment of the present invention, when batch forming is performed for the terminal blocks, the strip-shaped conductive sheet for preparing the terminal blocks can be placed on the upper part of the bottom plate 10, and then the conveying assembly 20 is used to convey the strip-shaped conductive sheet to the direction of the curling assembly 60 for a predetermined distance, and then the second driving assembly 80 drives the curling assembly 60 to rotate, so as to curl one end of the strip-shaped conductive sheet into a ring-shaped structure, and then the first driving assembly 40 drives the cutter 50 to move downward, and the cutter 50 cuts off the conductive sheet of the ring structure, so that the conductive sheet of the ring structure is separated from the subsequent strip-shaped conductive sheet, and then the pushing assembly 70 pushes the conductive sheet of the ring structure away from one end of the curling assembly 60, and then the conveying assembly 20 conveys the strip-shaped conductive sheet to the curling assembly 60 again. After the predetermined distance is delivered, the second driving component 80 drives the curling component 60 to rotate again to curl one end of the strip-shaped conductive sheet into a ring structure again, and then the first driving component 40 drives the cutter 50 to move downward again, and then cuts the conductive sheet of the ring structure again, and the pushing component 70 pushes the cut conductive sheet of the ring structure away from one end of the curling component 60 again, and repeats this cycle, so that the longer strip-shaped conductive sheet can be continuously formed into several conductive sheets of ring structures. Compared with the prior art, there is no need to use two sets of stamping equipment for the terminal conductive sheet, and the longer strip-shaped conductive sheet can be continuously and automatically curled into several conductive sheets of ring structures, which has the advantages of good forming effect and high forming efficiency of the terminal conductive sheet.

[0066] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
