Description

Technical Field

[0001] The present invention relates to the field of circuit breaker production, and in particular to a connecting plate online forming and feeding device and a method thereof. Background Art

[0002] The connection plate structure in the miniature circuit breaker is as follows Figure 1 As shown, there are two existing methods for loading the connecting plate onto the miniature circuit breaker. One is the manual mode: the connecting plate is pre-formed into a set shape, and then the worker places the connecting plate on the main line equipment, and then starts welding. After the equipment completes the welding, the finished product is unloaded, and the worker can continue to put the soft connection onto the equipment. All the processes in this mode cannot be superimposed, so the cycle time is long, and the worker is required to operate online all the time, which is labor-intensive. The other mode is the vibration plate mode. Compared with the manual mode, it has the advantages of superimposing processes and reducing the cycle time, but the disadvantage is that the connecting plate is relatively soft and easily deformed during the vibration process. It may entangle with each other and cause jamming, requiring manual intervention, and it is relatively frequent. At the same time, the number of connecting plates in the vibration plate cannot be too large (easy to entangle and jam), so multiple manual additions are required. Summary of the Invention

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0032] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0033] like Figure 2 and 3 As shown, an online forming and feeding equipment for connecting plates includes a front frame 1, an intermediate frame 2, and a rear frame 3 distributed in sequence. A wire-paying machine 4 and a leveling feeding mechanism 5 are installed on the front frame 1. The wire-paying machine 4 is a conventional machine that can be purchased on the market. The wire-paying machine 4 unwinds the strip to the leveling feeding mechanism 5. A material guiding mechanism 6 is installed on the intermediate frame 2. The leveling feeding mechanism 5 drives the strip 7 to enter the material guiding mechanism 6. A stepping feeding mechanism 9, a forming, stamping and shearing die 10, and a clamping and feeding mechanism 11 are installed on the rear frame 3. The wire-paying machine 4, the leveling feeding mechanism 5, the material guiding mechanism 6, the stepping feeding mechanism 9, the forming, stamping and shearing die 10, and the clamping and feeding mechanism 11 are arranged in sequence from front to back. The stepping feeding mechanism drives the strip coming out of the material guiding mechanism into the forming, stamping and shearing die. The forming, stamping and shearing die punches and shears the strip to produce a single connecting plate. The clamping and feeding mechanism clamps and transports the connecting plate to the next process.

[0034] like Figure 4 and 5 As shown, the leveling and feeding mechanism 5 includes a leveling fixed frame 51 and a guide wheel 52, a leveling seat 53, and a leveling drive motor 54 installed on the leveling fixed frame 51. Multiple guide wheels 52 guide the strip material into the leveling seat 53. The guide wheels 52 are divided into an upper group and a lower group. Adjacent guide wheels 52 are staggered. A leveling pressure wheel 55 is installed inside the leveling seat 53. The leveling pressure wheel 55 has two groups, an upper group and an lower group. The leveling drive motor 54 drives the leveling pressure wheel 53 to rotate and level the strip material 7. When the leveling pressure wheel 53 rotates, it drives the strip material to move and feed it to the moving guide wheel 66. A photoelectric switch 56 is installed between the guide wheel 52 and the leveling seat 53. The photoelectric switch 56 detects whether the strip material 7 passes by.

[0035] like Figure 6 As shown, the material guiding mechanism 6 includes a material guiding fixed frame 61 and a linear guide rail 62, an upper limit sensing switch 63, and a lower limit sensing switch 64 installed on the material guiding fixed frame 61. A slider 65 is installed on the side of the linear guide rail 62 for sliding movement. A movable guide wheel 66 is installed on the side of the slider 65. The strip is wound around the movable guide wheel 66. The function of the movable guide wheel 66 is to buffer the strip. When the movable guide wheel 66 reaches the detection position of the upper limit sensing switch 63, the leveling feeding mechanism 5 starts to feed the strip. When the movable guide wheel 66 reaches the detection position of the lower limit sensing switch 64, the leveling feeding mechanism 5 stops feeding the strip.

[0036] like Figure 7 and 8 As shown, the stepping feeding mechanism 9 includes a stepping fixed frame 91, a stepping induction switch 92, a clamping pliers 93, a stepping cylinder 94, a guide plate 95 and a pressing cylinder 96. The stepping fixed frame 91 is installed with a stepping induction switch 92. The stepping induction switch 92 determines whether there is material passing through. The clamping pliers 93 is located in front of the pressing cylinder 96. The clamping pliers 93 clamps one end of the material. The stepping cylinder 94 drives the clamping pliers 93 to approach the guide plate 95. The pressing cylinder 96 is installed on the guide plate 95. The stepping induction switch 92 determines that there is material, the clamping pliers 93 clamps the material, and the pressing cylinder 96 releases the material. The clamping pliers 93 of the stepping cylinder 94 advances a set distance at one end, the pressing cylinder 96 presses the material, the clamping pliers 93 releases the material, and the stepping cylinder 94 drives the clamping pliers 93 to retreat the distance just advanced. Such a reciprocating action realizes stepping feeding.

[0037] like Figure 9 As shown, the forming stamping and shearing die 10 includes a forming fixed frame 101, a stamping motor 102, an eccentric wheel 103, a stamping upper die 104 and a stamping lower die 105. The stamping motor 102 is installed on the forming fixed frame 101. The stamping motor 102 drives the stamping upper die 104 to move up and down through the eccentric wheel 103. The stamping upper die 104 and the stamping lower die 105 are conventional continuous stamping die structures. The stamping upper die 101 and the stamping lower die 105 are combined to stamp and shear as shown. Figure 1 Connecting plate shown.

[0038] like Figure 10 and 11As shown, the clamping and loading mechanism 11 includes a loading clamp 111, a movable seat 112, a flip plate 113, a pulley and a flip cylinder 115. The loading clamp 111 is installed on the movable seat 112, and the loading clamp 111 is connected to the flip plate 113. A pulley is installed on the side of the flip plate 113, and the pulley is placed in the flip groove 116 of the flip plate 113. The flip cylinder 115 drives the movable seat 112 to move forward. The loading clamp 111 is initially horizontal. At this time, the formed connecting plate is clamped at the shearing position of the forming stamping and shearing die 10. After cutting, the flip cylinder 115 drives the moving seat 112 to retreat, and the moving seat 112 drives the flip plate to retreat. Since the pulley installed on the side of the flip plate 113 is placed in the flip groove 116, the flip plate 113 will drive the loading clamp 111 to flip and change position and be sent to the tooling of the main machine by the grabbing component (such as a robot), realizing the entire automatic feeding process. In addition, the clamping and loading mechanism also includes a fixed seat 117 and a rotating shaft. The rotating shaft is installed inside the fixed seat 116, and the loading clamp 111 is connected to the flip plate 113 through the rotating shaft.

[0039] A method for online forming and loading of connecting plates using the above-mentioned device comprises the following steps:

[0040] ① The pay-off machine 4 unwinds the coiled material to the leveling and feeding mechanism 5;

[0041] ② The leveling and feeding mechanism 5 levels the strip material 7 and drives the strip material into the material guide mechanism 6;

[0042] ③ The material guide mechanism 6 guides the leveling and feeding mechanism 5 to start feeding the material in time;

[0043] ④ The stepping feeding mechanism 9 drives the strip material coming out of the material guiding mechanism 6 into the forming, stamping and shearing die 10;
