[0028] Embodiment 1: Figure 1 As shown, an automated processing equipment for terminal blocks is used to prepare terminal blocks with a length and width of 10mm and 8mm respectively, a thickness of 4-5mm, and a tolerance of ±0.1mm. The terminal blocks are made of CuZn40 material, and a threaded blind hole is set at the symmetric center of the terminal. The specification of the threaded blind hole is M3*0.5, that is, the main diameter of the thread is 3mm, the pitch is 0.5mm, the ratio of the hole depth of the threaded blind hole to the thickness of the metal terminal is: 39:43, and the distance from the threaded blind hole to the edge of its top surface is 4mm and 5mm respectively, with a tolerance of ±0.05mm, and a chamfer is set at the opening of the threaded blind hole, the specification of the chamfer is C0.2±0.1mm, and the effective thread in the threaded blind hole has at least 6 teeth.

[0029] An automated processing device for a terminal block includes a machine 1, on which a feeding assembly 2, a rough punching assembly 3, a chamfering assembly 4, a screw drilling assembly 5, and a blanking assembly 6 are arranged in a circular array in sequence, and a central rotating disk 7 is connected to the machine 1, and a plurality of placement tools 8 are arranged on the flow rotating disk 7 corresponding to the feeding assembly 2, the rough punching assembly 3, the chamfering assembly 4, the screw drilling assembly 5, and the blanking assembly 6, respectively. The flow rotating disk 7 is intermittently rotated by a central control module to drive the placement tool 8 to pass through the rough punching assembly 3, the chamfering assembly 4, the screw drilling assembly 5, and the blanking assembly 6 in sequence Specifically, in this embodiment, the rough drilling component 3, the chamfering component 4, the screw drilling component 5 and the blanking component 6 are arranged at equal intervals, and the distance between the equal intervals is the same as the distance between the plurality of placement tooling 8, so that when the flow plate 7 rotates intermittently, the placement tooling 8 and the workpiece thereon can be transferred between the rough drilling component 3, the chamfering component 4, the screw drilling component 5 and the blanking component 6, and the processing progress of the workpiece can be guaranteed to meet the requirements that the distance between the threaded blind hole and the top surface edge is 4mm and 5mm respectively, and the tolerance is ±0.05mm.

[0030] The machine table 1 is also provided with a number of positioning and calibration modules 9 located at the rough punching component 3, the chamfering component 4, the drilling component 5 and the blanking component 6. The positioning and calibration modules 9 are arranged toward the placement tool 8, and are used to obtain the status of the workpiece of the placement tool 8 to feed back to the central control module, and the central control module is used for centralized coordination and control, and cooperates with the positioning and calibration modules 9. When the fixed part 81 and the movable part 82 of the placement tool 8 clamp the workpiece to be processed, on the basis of reducing the activity of the workpiece, the positioning and calibration modules 9 are further arranged to detect the status of the placement tool 8 and the displacement activity of the workpiece. For example, when the placement tool 8 or the workpiece is detected, the positioning and calibration module 9 can detect and continuously output a high level or a low level signal. After the placement tool 8 rotates with the flow turntable 7, when the placement tool 8 is not detected, the output signal is flipped from a high level or a low level, and a low level or a high level is output. Forming a falling edge or a rising edge, the central control module can detect the flow state of the flow disk 7 and the processing state of the workpiece by using the digital pulse signal as a judgment with the positioning calibration module 9, and in this embodiment, the positioning calibration module 9 includes a support plate 91 and a Hall distance sensor 92 fixedly connected to the support plate 91, and the Hall distance sensor 92 is arranged toward the placement tool 8, and is used to obtain the distance between the terminal on the placement tool 8 and the Hall distance sensor 92. Through the setting of the Hall distance sensor 92, the distance between the workpiece and the positioning calibration module 9 can be detected, so as to ensure that the workpiece is placed in the tool 8. When the workpiece is transferred to the corresponding workstation, the distance between the workpiece and the corresponding electric punch is consistent, thereby ensuring that the distance between the threaded blind hole and its top edge meets the accuracy requirements, and when the terminal is used in products such as automobiles and relays, it can have good consistency, which is convenient for the installation of screws; The rough drilling component 3, the chamfering component 4 and the drilling component 5 are all provided with a mechanical limit mechanism 10 and a stroke detection mechanism 11, which are used to obtain and limit the movement stroke of the rough drilling component 3, the chamfering component 4 or the drilling component 5. In this embodiment, the mechanical limit mechanism 10 can directly limit the movement stroke of the corresponding component in a mechanical limit manner, which has good timeliness and reliability, and the stroke detection mechanism 11 feeds back the stroke status to the central control module in the form of electronic data information, so as to achieve coordination with the turntable 7, the cylinder and other components.

[0031] Specifically, the action section of the mechanical limit mechanism 10 includes a limit screw 101 and a damping rod 102, and the limit screw 101 and the damping rod 102 are connected to the drive shaft through a connecting piece 103. The limit screw 101 and the damping rod 102 are adjustably connected to the connecting piece 103 to adjust the limit of the mechanical limit mechanism 10 on the travel of the drive shaft, and the action section of the travel detection mechanism 11 includes an adjusting screw 110 and a plurality of feedback blocks 111 threadedly connected to the adjusting screw 110. The travel detection mechanism 11 also includes a travel Hall sensor 112. The plurality of travel Hall sensors 112 are arranged on the housing of the electric punch and connected to the central control module for dividing The position displacement of the feedback block 111 on the adjusting screw 110 is detected separately, and in response to a plurality of stroke Hall sensors 112, the displacement action of the feedback block 111 is detected respectively to control the drive shaft of the electric punch to stop or start, and the feedback block 111 can be fine-tuned on the adjusting screw 110 to control the length of the vertical stroke of the electric punch, thereby adjusting the depth of the drilled hole to meet the accuracy requirement of not penetrating the metal terminal and retaining the ratio of the hole depth of the threaded blind hole to the thickness of the metal terminal of 39:43, and in this embodiment, in the tapping step, a taper with only less than one tooth is selected, and the taper is assembled at the output end of the electric punch of the drilling assembly 5.

[0032] Among them, the feeding assembly 2 includes a feeding mechanism 21 and a cutting mechanism 222. The feeding mechanism 21 includes two groups of clamping members 211 and a placement frame 212. The two clamping members 211 are respectively fixedly and slidably connected to the placement frame 212. A reciprocating cylinder 213 is arranged on the placement frame 212. The telescopic end of the reciprocating cylinder 213 is connected to the slidable clamping member 211. Adjacent clamping members 211 intermittently clamp the linear material together. In this embodiment, the clamping member 211 adopts the same structure as the placement tool 8, a fixed block is provided as the fixed part 81, and a block-shaped movable part 82 is provided at the telescopic end of the cylinder, and the fixed part 81 and the movable part 82 are formed after the one side stroke facing each other is molded to form a clamping cavity consistent with the cross-section of the metal terminal, thereby realizing a firm clamping of the metal terminal, thereby improving the stability during the processing and ensuring the precision requirements.

[0033] The cutting assembly 22 includes a displacement base 221 and a cutting mechanism 222 arranged on the displacement base 221. The displacement base 221 is connected to the central control module through a radial cylinder. The radial cylinder responds to each rotation of the flow disk 7 to drive the cutting mechanism 222 to cut perpendicularly to the material along a tangential route to the flow disk 7. In conjunction with the reciprocating action of the reciprocating cylinder 213, when the clamping member 211 clamps the linear material in turn, the material can be delivered to the placement tool 8, and the telescopic stroke of the reciprocating cylinder 213 directly controls the length specification of the metal terminal. Through the intermittent displacement of the cutting assembly 22, the linear material can be cut, and along the route tangential to the flow disk 7 and perpendicular to the material, the flatness and parallelism of the end face of the metal terminal can be ensured.

[0034] The material unloading component 6 includes a stand 61, a vertical cylinder 62 is fixedly connected to the stand 61, a horizontal radial cylinder 63 is fixedly connected to the output end of the vertical cylinder 62, and a top column 64 is fixedly connected to the output end of the horizontal radial cylinder 63 for separating the processed terminal from the placement tool 8, so that when the placement tool 8 is transferred from the position where the drill thread assembly 5 is located and the next placement tool 8 is moved to the position of the drill thread assembly 5, the Hall distance sensor 92 is used to feedback to the central control module to control the material unloading component 6, so that the vertical cylinder 62 drives the horizontal radial cylinder 63 to move vertically, thereby lowering the horizontal The horizontal height of the radial cylinder 63 approaches the placement tool 8. While the horizontal radial cylinder 63 descends, the output section of the horizontal radial cylinder 63 extends, driving the top column 64 to extend first. When the horizontal radial cylinder 63 descends to a specified position (which may be an extreme position, depending on the signal of the cylinder and the size of the column), the horizontal radial cylinder 63 then contracts the top column 64. During the contraction process of the top column 64, the cylinder connected to the movable part 82 on the placement tool 8 is released and contracts, canceling the clamping of the metal terminal, and the top column 64 pushes the metal terminal out of the placement tool 8 to complete the unloading operation.

[0035] Through the improvement of automated processing equipment and the use of automated controlled processing, after the wire material is loaded, it undergoes automated drilling, chamfering, tapping and unloading to achieve continuous processing of the terminal block from wire cutting, drilling, chamfering and tapping. The automated assembly line processing does not require manual operation throughout the entire process, and is equipped with multiple sensors and mechanical limiters to effectively ensure the quality of the finished product of the terminal block, reduce production costs for the enterprise, and increase production capacity. It has high production efficiency and can effectively increase the production capacity of the terminal block, thereby achieving a profit point even when the unit price of the terminal block is low.

[0036] Secondly, by setting up the mechanical limit mechanism 10 and the stroke detection mechanism 11, the electric punching machine can accurately control the depth and degree of processing when performing drilling, chamfering and tapping operations, thereby accurately ensuring the ratio of the depth of the screw hole to the overall thickness of the terminal, and realizing the processing of threaded holes without penetrating the terminal, which not only ensures that the threaded holes are used for screw connection, but also avoids the influence on the strength of the overall structure of the terminal after penetration.

[0037] In addition, the Hall sensor, such as the Hall distance sensor 92, can detect and judge the metal terminal on the placement tool 8 when the flow plate 7 drives the placement tool 8 to flow, and then accurately process the metal terminal to improve the processing accuracy of the threaded hole to match the high-precision rigid requirements for the terminal; Embodiment 2, a control method for automated processing equipment for connecting terminals, adopts automated processing equipment for connecting terminals, and the steps include: S1. Place the long strip or linear material between the fixed portion 81 and the movable portion 82 of the clamp 211, align the material with the cross section of the placement tool 8, and adjust the stroke of the cylinder reciprocating drive according to the length of the finished terminal block; S2, the clamping member 211 clamps the material in turn, and sends the material to the placement tool 8 on the flow disk 7 under the action of the cylinder, and the displacement base 221 drives the cutting mechanism 222 toward the material between the placement tool 8 and the clamping member 211, and the cutting mechanism 222 moves along the tangential direction of the flow disk 7 and cuts along the edge of the placement tool 8; S3, after the cutting is completed, the cutting mechanism 222 is reset, and the flow disk 7 rotates intermittently under the drive of the motor, and the placement tool 8 holding the workpiece is transferred to the rough punching component 3. The Hall distance sensor 92 located at the rough punching component 3 detects the flow of the material on the placement tool 8 to output the material detection signal to the central control module. After monitoring that the material to be drilled is displaced to the specified position, the central control module controls the flow disk 7 to stop rotating and drives the electric punch of the rough punching component 3. When the mechanical limit mechanism 10 and the stroke detection mechanism 11 monitor the longitudinal displacement of the driving shaft of the electric punch to reach the set limit position, the rough punching component 3 is reset, and the Hall distance sensor 92 synchronously monitors the action of the rough punching component 3. While the rough punching operation is being performed, steps S1 and S2 are operated synchronously; S4, after completing the drilling operation of the rough drilling component 3, the central control module controls the flow turntable 7 to rotate, so that the placement tool 8 passing the corresponding station of the rough drilling component 3 moves with the workpiece to the corresponding station of the chamfering component 4, and through the Hall distance sensor 92 located at the chamfering component 4, after the Hall distance sensor 92 detects that the workpiece has moved to the specified position, the electric drilling machine of the chamfering component 4 is started to chamfer the blind hole position obtained after the rough drilling, and the mechanical limit mechanism 10 and the stroke detection mechanism 11 monitor. When the step S4 is operated, the steps S1-S3 are operated synchronously; S5, after completing step S4, when the workpiece inflow turntable 7 is transferred to the workstation of the thread drilling assembly 5, the Hall distance sensor 92 monitors the displacement change of the placement tool 8 and the workpiece, and the electric punch located in the thread drilling assembly 5 is operated to tap the chamfered workpiece, and the thread drill with only a taper less than one tooth is used to tap the blind hole. When operating in step S5, steps S1-S4 are operated synchronously; S6. After completing step S5, the flow turntable 7 moves the processed workpiece to the unloading component 6. The vertical cylinder 62 and the horizontal radial cylinder 63 act synchronously, and the movable part 82 of the placement tool 8 moves away from the fixed part 81 to release the clamping of the workpiece. The vertical cylinder 62 drives the horizontal radial cylinder 63 to approach the placement tool 8. At the same time, the output end of the horizontal radial cylinder 63 is extended and lowered to between the fixed part 81 and the movable part 82 of the placement tool 8 under the action of the vertical cylinder 62. The horizontal radial cylinder 63 is contracted and the workpiece is pushed through the top column 64 coaxial with the workpiece to complete the unloading. When step S6 is operated, steps S1-S5 are operated synchronously.

[0038] When quality control is performed on the processed metal terminals, a φ2.46mm pin gauge is used to measure the threaded blind hole. If there is obvious resistance and a large force is required to insert it, and it is difficult to remove it after insertion, it is unqualified. In addition, if there is obvious resistance or jamming during the selection of the through gauge direction of the threaded go / no-go gauge, and a large force is required to select it, it is also unqualified; Qualification standard: Use a φ2.6mm pin gauge to insert into the hole. If it cannot be inserted, it is qualified. Use a φ2.46mm pin gauge to insert into the threaded hole. If it can be inserted, it is qualified.
