Technical Field

[0001] The invention is applicable to the technical field of electronic component manufacturing, and provides an automatic production line for wiring terminals and a manufacturing method for wiring terminals. Background Art

[0002] The main function of the terminal block is to achieve electrical connection, making wire connection more convenient and quick. They are widely used in industrial automation, electronic equipment connection and other fields, and there are many types, including PCB board terminals, hardware terminals, nut terminals, spring terminals, etc. Fig.14 As shown in the figure, our company produces a four-pin terminal block for PCB boards. The terminal block is made of a straight strip, which is punched, cut and bent into a U shape. A circular ring component is fixed to the bottom end surface. The circular ring component and the through hole on the bottom end surface are tapped together to form a connected threaded hole. The tapping operation of the threaded hole must be completed in the last step. This is mainly for the consistency of the final threaded hole and to ensure the connection effect with the screw. In the previous common practice in the industry, the production and manufacturing of this terminal block is generally decomposed into three different steps, namely the stamping process, the bending and riveting process and the tapping process. These three steps are independent of each other, and manual loading and machine operation are required during the production process. The semi-finished products produced between the steps also need to be manually transported to the next process. The degree of automation is low and the labor cost is high. In the process of manual feeding, the safety is also low, and the overall economic benefits are not good. Summary of the invention

[0011] Furthermore, the riveting and bending unit includes a semi-finished product supporting seat, a circular riveting pressure rod is arranged inside the semi-finished product supporting seat, bending push blocks are respectively arranged on both sides of the semi-finished product supporting seat, the semi-finished product limiting discharge push block is arranged above the semi-finished product supporting seat, and the bottom of the semi-finished product limiting discharge push block is provided with a circular push limiting groove that is adapted to the outer side surface of the circular ring part.

[0012] Furthermore, the stamping feeding module also includes at least one group of material strip correction units, and the material strip correction unit includes two material strip correction blocks. The side of the material strip correction block is provided with a material strip correction groove adapted to the stamping material strip, and the two material strip correction blocks of the one material strip correction unit are respectively arranged on the left and right sides of the stamping material strip.

[0013] Furthermore, the automatic feeding unit includes two sets of belt pulley mechanisms and a feeding drive device which are spaced apart from each other, and the feeding drive device is used to drive the belt pulley mechanism to operate.

[0014] Furthermore, the tapping module also includes a semi-finished product transfer track, which is inclined from the semi-finished product support seat to the semi-finished product loading vibration plate. The semi-finished product limit installation unit includes a rotating placement plate and a placement plate driving device.

[0015] Furthermore, the rotating placement plate is arranged to be inclined relative to a horizontal plane, and the rotary tapping unit comprises at least two rotary tapping guns, and the rotary tapping guns are arranged to face the rotating placement plate.

[0016] At the same time, the present invention also provides a method for producing wiring terminals using the above-mentioned automatic wiring terminal production line, comprising the following steps:

[0017] S1: stamping step, firstly, the end of the stamping strip is passed through the strip deviation correction unit and the automatic feeding unit in sequence, and then installed in the continuous stamping die, at this time, the stamping machine and the automatic feeding unit are started, and the stamping strip is driven by the automatic feeding unit, and passes through the punching shaft, the notch punching block, and the slitting block in the continuous stamping die to punch the positioning hole, punch the end notch and the edge slitting process to obtain the terminal substrate;

[0018] S2: Bending and riveting step. The stamped material strip processed in step S1 is conveyed to the material strip bearing seat of the material strip cutting unit. At this time, the cutting positioning axis is inserted downward into the positioning hole processed in step S1. Then, the connection positions of the front and rear terminal substrates are cut and separated by the material strip cutting block. The separated terminal substrates are transported to the semi-finished product supporting seat. At this time, the circular ring parts are transported to the specified position of the terminal substrates by the circular ring feeding unit. The specific steps are as follows: first, a circular ring part is placed on the circular ring limiting step of the circular ring pushing block through the circular ring feeding trough, and then the circular ring pushing block pushes the circular ring part to the circular ring. The circular blanking rod is below the circular blanking rod. At this time, the lower end of the circular blanking rod passes downward through the circular ring part and the circular ring disengagement groove in turn and reaches the top of the terminal substrate. At this time, the circular ring pushing block is retracted, and the circular ring part will fall along the circular blanking rod to the terminal substrate. At this time, the circular blanking rod is withdrawn, and the semi-finished product limit discharging pushing block is actuated until the circular ring part is located in the circular ring pushing limiting groove. At this time, the circular ring riveting pressing rod is actuated upward to press the terminal substrate and the circular ring part together. At the same time, the bending pushing blocks on both sides of the semi-finished product supporting seat are actuated upward to bend the two ends of the terminal substrate into a specified angle, so that the terminal semi-finished product is obtained;

[0019] S3: Tapping step, the semi-finished product limit discharge push block continues to move, pushing the circular ring part through the groove wall of the circular ring push limit groove, and then pushing the semi-finished terminal away from the semi-finished product supporting seat into the semi-finished product feeding vibration plate, and then transferred from the semi-finished product feeding vibration plate to the semi-finished product placement groove of the rotating placement plate. The semi-finished terminal in the semi-finished product placement groove undergoes the tapping processing steps of two rotary tapping guns in sequence under the rotation of the rotating placement plate, and finally becomes a finished terminal and is detached from the rotating placement plate and stored in the designated position.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention can automatically complete the three main processes of punching, bending and ring riveting, and tapping of threaded holes of the terminal blocks through the punching and feeding module, the bending and riveting module, and the tapping module. At the same time, the automatic feeding unit is used to complete the automatic feeding of the material belt, the ring feeding vibration plate is used in conjunction with the ring feeding unit to complete the automatic positioning and feeding of the ring, and the semi-finished product feeding vibration plate is used to complete the automatic feeding of the semi-finished product before tapping, so that the whole process realizes the automatic flow operation without manual operation, which greatly reduces the production cost;

[0022] 2. In the tapping module of the present invention, the rotary placement disk is inclined to the horizontal plane, and the semi-finished product placement slot is opened at the edge of the rotary placement disk. In this way, after the wiring terminal in the semi-finished product placement slot is tapped through the threaded hole, the rotary placement disk continues to rotate, and the wiring terminal will eventually automatically detach from the semi-finished product placement slot at the edge opening of the rotary placement disk due to the inclination of the rotary placement disk, and fall into the storage device below. This design only requires a slight modification of the original structure to save the subsequent automatic material removal equipment, saving equipment costs;

[0023] 3. In the circular ring feeding unit, a circular ring disengagement groove for the circular ring blanking rod to pass through is provided at the bottom of the circular ring limiting step of the circular ring pushing block. In this way, during the feeding process of the circular ring parts, before the circular ring pushing block is separated from the circular ring parts, the circular ring blanking rod used for guiding the blanking of the circular ring parts can directly pass through the circular ring limiting step and move into place. In this way, it is not easy for the circular ring parts to be separated from the circular ring blanking rod due to insufficient limiting in a short time after the circular ring pushing block is separated, resulting in leakage of the installation of the circular ring.

[0047] In this automatic production line for wiring terminals, as shown in the attached Figure 3 As shown, the stamping feeding module 100 includes a stamping machine 110, a continuous stamping die 120, an automatic feeding unit 130 and at least one set of strip deviation correction units, the strip deviation correction unit includes two strip deviation correction blocks 140, as shown in the attached Figure 6 As shown, the side of the strip correction block 140 is provided with a strip correction groove 141 adapted to the stamping strip 500, and the two strip correction blocks 140 of a strip correction unit are respectively arranged on the left and right sides of the stamping strip 500, so that the two strip correction grooves 141 of the two strip correction blocks 140 can correct the stamping strip 500 from both sides, thereby improving the correction effect, and the stamping strip 500 enters the automatic feeding unit 130 after correction, as shown in the attached Figure 5As shown, the automatic feeding unit 130 includes two groups of belt pulley mechanisms 131 arranged at intervals and a feeding drive device 132. The belt pulley mechanism 131 is a conventional setting, and its structure is similar to a tank track wheel. A track is arranged on the outside of a group of guide wheels. The feeding drive device 132 is generally a speed-regulating motor, which can drive the belt pulley mechanism 131 at a required speed. The stamping material belt 500 is arranged between the two groups of belt pulley mechanisms 131. When the belt pulley mechanism 131 rotates, the friction force of the track drives the stamping material belt 500 to automatically feed forward to the continuous stamping die 120. The continuous stamping die 120 is installed on the stamping machine 110. The stamping machine 110 is a prior art, which uses a fast lifting cylinder to drive the upper and lower dies of the continuous stamping die 120 to reciprocate quickly. The structure of the continuous stamping die 120 is generally conventional technology, as shown in the attached figure. Figure 4 As shown, the mold core includes a punching shaft 121, a notch punching block 122 and a slitting block 123;

[0048] As attached Figure 7 As shown, the bending and riveting module 200 includes a material strip cutting unit 210, a circular ring feeding unit 220, a riveting and bending unit 230, a semi-finished product limiting discharge pushing block 240 and a plurality of driving units. The driving unit is a prior art, and generally includes a servo motor, a cylinder, a hydraulic cylinder and other power sources, and cooperates with a connecting rod, a gear set, a screw mechanism and other power conversion mechanisms to achieve various forms of driving force. The aforementioned plurality of driving units are used to drive the aforementioned material strip cutting unit 210, the circular ring feeding unit 220, the riveting and bending unit 230 and the semi-finished product limiting discharge pushing block 240. Specifically, refer to the attached Figure 8 As shown, the strip cutting unit 210 includes a strip bearing seat 211, and a cutting positioning shaft 212 and a strip cutting block 213 are arranged above the strip bearing seat 211. The cutting positioning shaft 212 is used to be inserted into the positioning hole, and the strip cutting block 213 is used to cut and separate the single terminal strip at the end from the stamping strip 500, so as to enter the riveting and bending unit 230 for subsequent processing. Fig. 9The ring loading unit 220 includes a ring feeding trough 221, a ring pushing block 222 and a ring blanking rod 223. The aforementioned ring loading vibration plate 400 is used to supply ring parts to the ring feeding trough 221 of the ring loading unit 220. The ring pushing block 222 includes a ring limiting step. The bottom of the ring limiting step is provided with a ring escaping groove for the ring blanking rod 223 to pass through. The ring pushing block 222 is used to push the ring parts from the ring feeding trough 221 to the position of the ring blanking rod 223. Before the parts are separated, the ring blanking rod 223 can directly pass through the ring parts and the ring limiting steps and directly reach the position, so it is not easy for the ring parts and the ring blanking rod 223 to be separated due to insufficient limiting in a short time after the ring pushing block 222 is separated, resulting in the ring missing installation. The riveting and bending unit 230 includes a semi-finished product supporting seat, and the single terminal strip punched from the strip cutting unit 210 is transferred to the semi-finished product supporting seat, and the ring parts are guided and transported to the upper end surface of the terminal strip by the ring blanking rod 223, and as shown in the attached Fig.10 As shown, a circular riveting pressure rod 231 is arranged in the semi-finished product supporting seat. It should be noted that for the sake of clarity, Fig.10 The structure of the semi-finished product supporting seat is hidden in the figure. The semi-finished product supporting seat is provided with bending push blocks 232 on both sides, and the semi-finished product limiting discharge push block 240 is provided above the semi-finished product supporting seat. Fig.11 As shown, the bottom of the semi-finished product limiting discharging push block 240 is provided with a circular ring pushing limiting groove 241 adapted to the outer side surface of the circular ring part. After the terminal strip and the circular ring part are successfully placed in place, the semi-finished product limiting discharging push block 240 is pushed out to the top of the circular ring part. At this time, the circular ring part is located in the circular ring pushing limiting groove 241, and the circular ring pushing limiting groove 241 will limit the upper end of the circular ring part. At this time, the circular ring riveting pressure rod 231 and the bending push block 232 can be moved upward to complete the riveting of the terminal strip and the circular ring part and the bending of the two ends of the terminal strip. Then the semi-finished product limiting discharging push block 240 continues to be pushed outward, so that the riveted semi-finished terminal strip can be pushed out of the bending riveting module 200.

[0049] See attached Fig.12As shown, the tapping module 300 includes a semi-finished product transfer track 340, a semi-finished product feeding vibration disk 310, a semi-finished product limiting installation unit 320 and a rotary tapping unit 330. The semi-finished product transfer track 340 is inclined from the semi-finished product supporting seat to the semi-finished product feeding vibration disk 310. The semi-finished product of the terminal block of the bending and riveting module 200 pushed out by the semi-finished product limiting discharge push block 240 is transferred to the semi-finished product feeding vibration disk 310 via the semi-finished product transfer track 340, and the semi-finished product feeding vibration disk 310 supplies the semi-finished product workpiece to the semi-finished product limiting installation unit 320 through vibration feeding. Between the semi-finished product feeding vibration disk 310 and the semi-finished product limiting installation unit 320, in order to feed accurately, an automatic clamp can also be used to cooperate with a moving mechanism to achieve accurate feeding, as shown in the attached Fig.13 As shown, the semi-finished product limiting installation unit 320 includes a rotating placement disk 321 and a placement disk driving device 322. The placement disk driving device 322 is used to drive the rotating placement disk 321 to rotate. The rotating placement disk 321 is provided with a plurality of semi-finished product placement grooves in a circular array. The rotating placement disk 321 is arranged to be inclined to the horizontal plane. At the same time, the semi-finished product placement groove is provided with an opening at the edge position of the rotating placement disk 321. In this way, when the wiring terminal in the semi-finished product placement groove is subjected to the threaded hole tapping operation, the rotating placement disk 321 continues to rotate. Finally, the finished wiring terminal 600 will automatically detach from the semi-finished product placement groove at the edge opening of the rotating placement disk 321 due to the inclination of the rotating placement disk 321, and fall into the storage device below. The rotating tapping unit 330 includes at least two rotating tapping guns 331. The rotating tapping gun 331 is a prior art, which drives the tapping drill rod to realize the function of drilling the threaded hole. The rotating tapping gun 331 is arranged facing the rotating placement disk 321.

[0052] S2: Bending and riveting step. The stamping strip 500 processed in step S1 is conveyed to the strip bearing seat 211 of the strip cutting unit 210. At this time, the cutting positioning shaft 212 is inserted downward into the positioning hole processed in step S1. Then, the connection positions of the front and rear terminal substrates are cut and separated by the strip cutting block 213. The separated terminal substrates are transported to the semi-finished product supporting seat. At this time, the circular ring parts are transported to the specified position of the terminal substrates by the circular ring feeding unit 220. The specific steps are as follows: first, a circular ring part is placed on the circular ring limiting step of the circular ring pushing block 222 through the circular ring feeding slot 221, and then the circular ring pushing block 222 pushes the circular ring part to the circular ring. The lower end of the circular blanking rod 223 passes downward through the circular part and the circular disengagement groove in turn to reach the top of the terminal substrate. At this time, the circular pushing block 222 is retracted, and the circular part will fall along the circular blanking rod 223 to the terminal substrate. At this time, the circular blanking rod 223 is withdrawn, and the semi-finished product limiting discharge pushing block 240 is actuated until the circular part is located in the circular pushing limiting groove 241. At this time, the circular riveting pressing rod 231 is actuated upward to rivet the terminal substrate and the circular part together. At the same time, the bending pushing blocks 232 on both sides of the semi-finished product supporting seat are actuated upward to bend the two ends of the terminal substrate into a specified angle, so that the semi-finished terminal is obtained.

[0053] S3: Tapping step, the semi-finished product limiting discharge push block 240 continues to move, pushing the annular part through the groove wall of the annular push limiting groove 241, and then pushing the semi-finished terminal away from the semi-finished product supporting seat into the semi-finished product loading vibration plate 310, and then transferred from the semi-finished product loading vibration plate 310 to the semi-finished product placement groove of the rotating placement plate 321. The semi-finished terminal in the semi-finished product placement groove undergoes the tapping processing steps of two rotary tapping guns 331 in sequence under the rotation of the rotating placement plate 321, and finally becomes a finished terminal 600 and is detached from the rotating placement plate 321 and stored in a designated position.
