[0002] Terminal blocks are an accessory product used to achieve electrical connections and are a type of connector. Existing terminal blocks require the use of stamping equipment to punch copper, aluminum, copper alloy, or 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 wires.

[0003] Therefore, the existing production of terminal conductive sheets requires two processes: punching and stamping.

[0045] Please refer to Figure 1 、 Figure 2 and Figure 3, this embodiment provides a batch stamping and forming mechanism for terminal blocks, including a bottom plate 10, a conveying component 20, a first driving component 40, a cutting knife 50, a curling component 60, a pushing component 70, and a second driving component 80. A first support plate 101, a second support plate 102, and a third support plate 103 are fixedly arranged on the upper part of the bottom plate 10. The conveying component 20 is arranged on the side wall of the first support plate 101 and is used to convey the strip-shaped conductive sheet towards the curling component 60. The curling component 60 is arranged on one side of the third support plate 103, and the second driving component 80 is arranged on the other side of the third support plate 103 and is used to drive the curling component 60 to rotate so as to curl one end of the strip-shaped conductive sheet conveyed by the conveying component 20 into an annular structure. The cutting knife 50 is arranged above the curling component 60, and the first driving component 40 is installed on the side wall of the second support plate 102. After the curling component 60 curls one end of the conductive sheet into an annular structure, the first driving component 40 is used to drive the cutting knife 50 to move downward to cut the conductive sheet with the annular structure. The pushing component 70 is installed on the curling component 60. After the cutting knife 50 cuts the conductive sheet with the annular structure, the pushing component 70 is used to push the conductive sheet with the annular structure away from one end of the curling component 60.

[0046] When batch-forming 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 component 20 is used to convey the strip-shaped conductive sheet towards the curling component 60 for a predetermined distance. Subsequently, the second driving component 80 drives the curling component 60 to rotate, thereby curling one end of the strip-shaped conductive sheet into an annular structure. Then, the first driving component 40 drives the cutting knife 50 to move downward, and the cutting knife 50 cuts the conductive sheet with the annular structure, so that the conductive sheet with the annular structure is separated from the subsequent strip-shaped conductive sheet. Subsequently, the pushing component 70 pushes the conductive sheet with the annular structure away from one end of the curling component 60. Then, the conveying component 20 conveys the strip-shaped conductive sheet towards 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-shaped conductive sheet into an annular structure again. Then, the first driving component 40 drives the cutting knife 50 to move downward again to cut the conductive sheet with the annular structure again, and the pushing component 70 pushes the cut conductive sheet with the annular structure away from one end of the curling component 60 again. By repeating this cycle, the longer strip-shaped conductive sheet can be continuously formed into several conductive sheets with annular structures.

[0047] Please refer to Figure 1 , in one embodiment, the first driving component 40 includes a hydraulic cylinder 401 and a lifting rod 402. The hydraulic cylinder 401 is fixedly arranged on the side wall of the second support plate 102, the lifting rod 402 is fixedly installed at the output end of the hydraulic cylinder 401, and the cutting knife 50 is fixedly arranged at one end of the lifting rod 402.

[0048] After the second driving component 80 drives the curling component 60 to rotate and then winds one end of the strip-shaped conductive sheet into an annular structure, the hydraulic cylinder 401 drives the lifting rod 402 to move downward, the lifting rod 402 drives the cutting knife 50 to move downward, and the cutting knife 50 acts on the strip-shaped conductive sheet, thereby cutting the conductive sheet of the annular structure.

[0049] Please refer to Figure 1 、 Figure 3 and Figure 4 In one embodiment, the curling component 60 includes a reel 601, a winding rod 603 and a support 605. One end of the reel 601 is fixedly provided with a rotating shaft 606. The end of the rotating shaft 606 away from the reel 601 penetrates through the third support plate 103 and is rotationally matched with the third support plate 103. The support 605 is fixedly arranged on the side wall of the reel 601. One end of the winding rod 603 is rotatably connected to the support 605, and the other end extends along the length direction of the reel 601. The winding rod 603 is distributed in parallel with 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 arranged outside the rotating shaft 606. One end of the support rod 801 is fixedly connected to the cutting knife 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 meshes with the second gear 803.

[0050] The conveying component 20 conveys the strip-shaped conductive sheet between the reel 601 and the winding rod 603 by a predetermined distance. Then the hydraulic rod 401 drives the lifting rod 402 to move downward, thereby driving the cutting knife 50 to move downward. When the cutting knife 50 moves downward, it drives the rack rod 802 to move downward through the support rod 801. By the meshing action of the rack rod 802 and the second gear 803, the rotating shaft 606 is driven to rotate. When the rotating shaft 606 rotates, it drives the reel 601 and the winding rod 603 to rotate. When the winding rod 603 rotates, it acts on one end of the strip-shaped conductive sheet to drive the strip-shaped conductive sheet to bend and wrap around the outside of the reel 601, thereby forming a conductive sheet of an annular structure. When one end of the strip-shaped conductive sheet rotates around the reel 601 for one circle, the cutting knife 50 moves downward and acts on the strip-shaped conductive sheet, thereby cutting the conductive sheet of the annular structure; after the conductive sheet of the annular structure is cut off, the hydraulic cylinder 401 drives the lifting rod 402 to move upward, thereby driving the cutting knife 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 reverse direction through the reverse meshing action with the second gear 803, and then drives the reel 601 and the winding rod 603 to rotate in the reverse direction.

[0051] Please refer to Figure 4 and Figure 5, in one embodiment, a notch 602 is formed in the reel 601 in the radial direction, a threaded section 604 is formed on the outer surface of the winding rod 603, the pushing component 70 includes a first gear 701, a sliding sleeve 702 and a push rod 703. The first gear 701 is fixedly installed on the outer surface of the winding rod 603. The sliding sleeve 702 is sleeved on the outer surface of the winding rod 603 and is in threaded cooperation with the threaded section 604. One end of the push rod 703 is fixedly connected to the sliding sleeve 702, and the other end penetrates through the reel 601 from the notch 602. A power component is arranged on one side of the third support plate 103. During the reverse rotation of the reel 601 and the winding rod 603, the power component is used to drive the first gear 701 to rotate forward and backward reciprocally.

[0052] After the conductive sheet in the annular structure is cut off, the hydraulic cylinder 401 drives the lifting rod 402 to move upward, thereby driving the reel 601 and the winding rod 603 to rotate in the reverse direction. At this time, the power component drives the first gear 701 to rotate forward, thereby driving the winding rod 603 to rotate forward relative to the support 605. Through the threaded cooperation between the threaded section 604 on the outer surface of the winding rod 603 and the sliding sleeve 702, the sliding sleeve 702 is driven to move along the length direction of the winding rod 603. The sliding sleeve 702 drives the push rod 703 to make the push rod 703 slide along the inside of the notch 602, thereby pushing the conductive sheet in the annular structure sleeved on the outer surface of the reel 601 away from one end of the reel 601. After the conductive sheet in the annular structure is pushed away from one end of the reel 601, the power component drives the first gear 701 to rotate in the reverse direction, thereby driving the winding rod 603 to rotate in the reverse direction relative to the support 605. At this time, through the reverse threaded cooperation between the threaded section 604 and the sliding sleeve 702, the sliding sleeve 702 is driven to slide reversely along the length direction of the winding rod 603. The sliding sleeve 702 drives the push rod 703 to slide reversely along the inside of the notch 602, so as to realize the reset of the push rod 703 to push away the conductive sheet in the annular structure sleeved on the outer surface of the reel 601 again.

[0053] Please refer to Figure 6 , in one embodiment, the power component includes a second arc-shaped plate 1034, a second helical tooth piece 1035 and a second elastic member 1036. The second arc-shaped plate 1034 is fixedly arranged on the side wall of the third support plate 103. The center of the arc of the second arc-shaped plate 1034 coincides with the center of the reel 601. There are several groups of the second helical tooth pieces 1035. Several of the second helical tooth pieces 1035 are hinged on the inner wall of the arc of the second arc-shaped plate 1034 and are distributed at intervals along the inner wall of the arc of the second arc-shaped plate 1034. One side of each group of the second helical tooth pieces 1035 is connected to the second arc-shaped plate 1034 through a group of the second elastic members 1036. The second elastic member 1036 is used to provide elastic support for the second helical tooth piece 1035.

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

[0055] Please refer to Figure 7 In one embodiment, the power assembly further includes a first arc-shaped plate 1031, a first helical blade 103, and a first elastic member 1033. The first arc-shaped plate 1031 is fixedly arranged on the side wall of the third support plate 103. The center of the arc of the first arc-shaped plate 1031 coincides with the center of the reel 601. There are several groups of the first helical blades 1032. The several first helical blades 1032 are hingedly arranged on the outer arc wall of the first arc-shaped plate 1031 and are distributed at intervals along the outer arc wall of the first arc-shaped plate 1031. One side of each group of the first helical blades 1032 is connected to the first arc-shaped plate 1031 through a group of the first elastic members 1033. The first elastic member 1033 is used to provide elastic support for the first helical blade 1032.

[0056] When the hydraulic cylinder 401 drives the lifting rod 402 to move downward, thereby driving the reel 601 and the winding rod 602 to rotate, the first gear 701 rotates along the outer side of the first arc plate 1031, and then acts on a plurality of first helical plates 1032 and drives the plurality of first helical plates 1032 to deflect sequentially in the direction of the first arc plate 1031. The plurality of first helical plates 1032 cannot mesh with the first gear 701, and the winding rod 603 cannot rotate relative to the support 605. When the push rod 703 pushes the annular conductive sheet away from one end of the reel 601, as the reel 601 and the winding rod 603 continue to rotate in the reverse direction, the first gear 701 can act on a plurality of first helical plates 1032 and enter a meshing state with the plurality of first helical plates 1032. The first gear 701 drives the winding rod 603 to rotate in the reverse direction relative to the support 605, and then drives the push rod 703 to slide reversely along the inside of the notch 602 through the reverse thread cooperation of the threaded section 604 and the sliding sleeve 702, thereby realizing the reset of the push rod 703.

[0057] Please refer to Figure 1 , in one embodiment, the conveying assembly 20 includes a motor 201 and conveying rollers 202. There are two groups of the conveying rollers 202, and the two groups of the conveying rollers 202 are rotatably installed on one side of the first support plate 101 and are distributed at intervals up and down. The motor 201 is fixedly installed on the side wall of the first support plate 101 and is used to drive the two groups of the conveyed conveying rollers 202 to rotate relatively.

[0058] The motor 201 drives the two groups of conveying rollers 202 to rotate relatively, and the friction of the two groups of conveying rollers 202 on the strip-shaped conductive sheet is used to convey the strip-shaped conductive sheet between the reel 601 and the winding rod 603. Cooperating with the up and down movement of the hydraulic cylinder 401 driving the cutter 50 and the reciprocating rotation of the reel 601 and the winding rod 603, the continuous forming of the strip-shaped conductive sheet is realized.

[0059] Please refer to 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 winding rod 603 to rotate through the meshing of the rack rod 802 and the second gear 803, the limiting assembly 30 is used to limit the strip-shaped conductive sheet, so as to ensure that the winding rod 603 can stably wind one end of the strip-shaped conductive sheet outside the reel 601 to improve the forming effect.

[0060] Please refer to Figure 1, in one embodiment, the limiting component 30 includes a pressing plate 301, a third elastic member 302 and a pressing rod 303. The pressing rod 303 vertically penetrates the lifting rod 402 and is movably engaged with the lifting rod 402. The pressing plate 301 is fixedly installed at the bottom of the pressing rod 303. One end of the third elastic member 302 is connected to the pressing plate 301, and the other end is connected to the lifting rod 402 for providing elastic support to the pressing plate 301.

[0061] While the hydraulic cylinder 401 drives the lifting rod 402 to move downward and then drives the cutting knife 50 to move downward, the lifting rod 402 drives the pressing plate 301 to move downward through the third elastic member 302. The pressing 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 bar 802 meshes with the second gear 803, and then drives the reel 601 and the winding rod 603 to rotate. When the winding rod 603 rotates, since the strip-shaped conductive sheet is in a pressed state, the winding rod 603 can stably wind one end of the strip-shaped conductive rod outside the reel 601, thereby forming a conductive sheet with a ring structure. After the pressing plate 301 presses the strip-shaped conductive sheet, the two conveying rollers 202 slide relative to the strip-shaped conductive sheet, and then stop conveying the strip-shaped conductive sheet; after the hydraulic cylinder 401 drives the lifting rod 402 and the cutting knife 50 to move upward and the rack bar 802 and the second gear 803 drive the reel 601 and the winding rod 603 to rotate in the reverse direction to the initial position, the lifting rod 402 pulls the pressing plate 301 through the third elastic member 302 to make the pressing plate 301 move upward, and the pressing plate 301 is separated from the strip-shaped conductive sheet to release the pressing state of the strip-shaped conductive sheet. At this time, the two conveying rollers 202 continue to convey the strip-shaped conductive sheet until the strip-shaped conductive sheet moves a predetermined distance again between the reel 601 and the winding rod 603, and then the hydraulic cylinder 401 drives the lifting rod 402 to move downward again, and then curls and forms one end of the strip-shaped conductive sheet again.

[0062] Please refer to Figure 1 , in one embodiment, a support plate 104 is fixedly provided at the upper part of the bottom plate 10 at a position 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-shaped conductive sheet against the upper part of the support plate 104. Through the cooperation of the pressing plate 301 and the support plate 104, the pressing effect of the strip-shaped 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 can be springs or metal elastic sheets, and there is no limitation here.

[0065] In the embodiment of the present invention, when batch forming the terminal, the strip-shaped conductive sheet for preparing the terminal can be placed on the upper part of the bottom plate 10, and then the conveying assembly 20 conveys the strip-shaped conductive sheet a predetermined distance in the direction of the curling assembly 60. Subsequently, the second driving assembly 80 drives the curling assembly 60 to rotate, thereby curling one end of the strip-shaped conductive sheet into an annular structure. Then, the first driving assembly 40 drives the cutter 50 to move downward, and the cutter 50 cuts off the conductive sheet of the annular structure, so that the conductive sheet of the annular structure is separated from the subsequent strip-shaped conductive sheet. Subsequently, the pushing assembly 70 pushes the conductive sheet of the annular structure away from one end of the curling assembly 60. Then, the conveying assembly 20 conveys the strip-shaped conductive sheet a predetermined distance in the direction of the curling assembly 60 again, and the second driving assembly 80 drives the curling assembly 60 to rotate again to curl one end of the strip-shaped conductive sheet into an annular structure again. Then, the first driving assembly 40 drives the cutter 50 to move downward again, so as to cut off the conductive sheet of the annular structure again, and the pushing assembly 70 pushes the cut conductive sheet of the annular structure away from one end of the curling assembly 60 again. By repeating this cycle, the long strip-shaped conductive sheet can be continuously formed into several conductive sheets of annular structures. Compared with the prior art, two sets of stamping equipment are not required for forming the conductive sheet of the terminal, and the long strip-shaped conductive sheet can be continuously and automatically curled into several conductive sheets of annular structures, which has the advantages of good forming effect and high forming efficiency for the conductive sheet of the terminal.

[0066] The above describes the preferred embodiments of the present invention in detail. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art, various changes can be made without departing from the purpose of the present invention.
