Its enclosure contains structures including mechanical operating mechanisms, arc extinguishing devices, protective devices, and control circuits. The circuit breaker enclosure is usually cubic in structure, mainly used to protect its internal structure and to provide insulation protection.

[0003] During the production and assembly of circuit breakers, after the outer casing is assembled and inspected in advance, it needs to be disassembled to facilitate the subsequent assembly of other components inside. However, the existing manual disassembly method is difficult, cannot be carried out continuously, has low work efficiency, and has a poor yield.

[0004] Therefore, this application provides an automatic circuit breaker unpacking mechanism to meet the requirements. Utility Model Content

[0005] In view of this, the purpose of this application is to provide an automatic circuit breaker disassembly mechanism to improve the efficiency of disassembly.

[0006] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0007] An automatic disassembly mechanism for a circuit breaker includes a placement slot, a push plate, and an electric push rod. The placement slot is a slot-shaped structure with an open top. The push plate is slidably disposed in the groove of the placement slot. The electric push rod is disposed at the end of the placement slot to push the push plate to slide. A slot is opened at the end of the side wall of the placement slot. A U-shaped plate is disposed at the front end of the side wall opening of the placement slot. A wedge is disposed on the vertical part of the U-shaped plate. An electric push rod is disposed at the end of the placement slot. A pressure block is disposed at the end of the electric push rod. The pressure block is slidably disposed in the slot at the end of the side wall of the placement slot.

[0008] Preferably, a receiving groove is provided parallel to one side of the placement groove, and the receiving groove is connected to the placement groove.

[0009] Preferably, the adjacent surfaces of the horizontal portion of the U-shaped plate are provided with grooves, and a slider is slidably connected in the groove of the horizontal portion of the U-shaped plate, the slider being disposed at the front end of the pressure block.

[0010] Preferably, the horizontal portion of the U-shaped plate has a strip-shaped hole, the slider passes through the strip-shaped hole in the horizontal portion of the U-shaped plate, a limit block is provided on the outer side of the U-shaped plate, the limit block is U-shaped, a locking block is slidably connected to the opening of the limit block, the locking block is connected to one side of the slider, and a spring is provided between the locking block and the limit block.

[0011] Preferably, the locking block includes an inclined slope, and the locking block is positioned in the output direction of the electric push rod two;

[0012] Guide blocks are provided on both the upper and lower sides of the pressure block. Each guide block has a pointed tip and is positioned at the same height as the locking block.

[0013] Preferably, the width of the pressing block is consistent with the width of the side wall groove of the placement groove, and the bottom surface of the pressing block is fitted to the inner bottom surface of the placement groove.

[0014] Preferably, the wedge is located at the end of the slider, and the perpendicular bisector of the wedge is located in front of the contact area of ​​the two sliders.

[0015] In the above scheme, by setting up a placement slot, an electric push rod, a push plate, and a receiving slot, multiple circuit breakers that need to be disassembled can be stacked inside both the placement slot and the receiving slot.

[0023] Placement slot 1, push plate 101, electric push rod 102, receiving slot 103, U-shaped plate 2, wedge block 201, slider 202, limit block 203, locking block 204, spring 205, electric push rod 23, pressure block 301, guide block 302. Detailed Implementation

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 An automatic circuit breaker disassembly mechanism is provided in the embodiments of this application, including a placement groove 1, a push plate 101, and an electric push rod 102. The placement groove 1 is a groove-shaped structure with an open top. The push plate 101 is slidably disposed in the groove of the placement groove 1. The electric push rod 102 is disposed at the end of the placement groove 1 to push the push plate 101 to slide. A slot is opened at the end of the side wall of the placement groove 1. A U-shaped plate 2 is provided at the front end of the side wall opening of the placement groove 1. A wedge block 201 is provided on the vertical part of the U-shaped plate. An electric push rod 3 is provided at the end of the placement groove 1. A pressure block 301 is provided at the end of the electric push rod 3. The pressure block 301 is slidably disposed in the slot at the end of the side wall of the placement groove 1.

[0025] The placement slot 1 has a long strip-shaped placement space to facilitate the neat stacking of circuit breaker housings. Workers can place multiple circuit breakers into the placement slot 1 at one time. The circuit breaker is pushed to one end of the placement slot 1 by the electric push rod 102. The electric push rod 3 drives the pressure block 301 to push the circuit breaker out of the slot 1. The pressure block 301 squeezes the circuit breaker into the U-shaped plate 2. After the circuit breaker contacts the wedge block 201, it is split in two under the action of the squeezing force, thus realizing the disassembly of the circuit breaker housing.

[0026] The width of the side wall slot of the placement slot 1 can be the same as the width of the circuit breaker, thereby ensuring that the pressure block 301 pushes out only one circuit breaker at a time. The pressure block 301 moves away from the side of the U-shaped plate 2 until it leaves the placement space inside the placement slot 1. Then, the next circuit breaker can be pushed to the slot position by the electric push rod 3. The above operation is repeated to achieve continuous and automated disassembly work.

[0027] In this embodiment, as Figures 2-4 As shown, a receiving groove 103 is provided parallel to one side of the placement groove 1, and the receiving groove 103 is connected to the placement groove 1.

[0028] Through the organic cooperation of the electric push rod 102 and the push plate 101, the circuit breakers in the placement slot 1 are pushed to the front of the pressure block 301 in a continuous manner. At this time, the workers can put the circuit breakers into the receiving slot 103. After the circuit breakers in the placement slot 1 are cleared, the circuit breakers in the receiving slot 103 are replenished into the placement slot 1 in one go, thereby speeding up the production cycle and improving work efficiency.

[0029] The adjacent surfaces of the horizontal portion of the U-shaped plate 2 are provided with grooves, and a slider 202 is slidably connected in the groove of the horizontal portion of the U-shaped plate 2. The slider 202 is located at the front end of the pressure block 301.

[0030] A slider 202 is provided inside the U-shaped plate. The circuit breaker pushed out by the pressure block 301 can move onto the slider 202. The sliding direction of the slider 202 is consistent with the direction of separation of the circuit breaker housing. Thus, when the circuit breaker housing is split in two, the sliding of the two sliders 202 can reduce the occurrence of scratches on the circuit breaker housing and improve the yield rate.

[0031] The horizontal portion of the U-shaped plate 2 has a strip-shaped hole, and the slider 202 passes through the strip-shaped hole in the horizontal portion of the U-shaped plate 2. A limit block 203 is provided on the outer side of the U-shaped plate 2. The limit block 203 is U-shaped, and a locking block 204 is slidably connected to the opening of the limit block 203. The locking block 204 is connected to one side of the slider 202, and a spring 205 is provided between the locking block 204 and the limit block 203.

[0032] The cooperation between the limiting block 203 and the locking block 204 can limit the position of the slider 202 and provide a guiding effect for the sliding of the slider 202, making it more stable when sliding. The slider 202 is reset by the spring 205 pressing the locking block 204, thereby meeting the needs of continuous production.

[0033] The locking block 204 includes an inclined ramp surface and is positioned in the output direction of the electric push rod 3.

[0034] Guide blocks 302 are provided on both the upper and lower sides of the pressure block 301. The guide block 302 includes a tip. The guide block 302 and the locking block 204 are set at the same height.

[0035] After the pressure block 301 pushes the circuit breaker into the U-shaped plate 2, the tip of the guide block 302 presses against the inclined surface of the locking block 204, causing the locking block 204 to drive the slider 202 to move to both sides. The two sliders 202 move away from each other, causing the circuit breaker housing to split into two. Then the pressure block 301 continues to push the two housings towards the wedge block 201, which further increases the distance between the two housings, thereby completing the separation of the housing from the slider 202.

[0036] One way to ensure production continuity is to install a conveyor belt at the bottom of the U-shaped plate 2 to transport the disassembled circuit breaker housings to the next process.

[0037] The width of the pressure block 301 is the same as the width of the side wall groove of the placement groove 1, and the bottom surface of the pressure block 301 is attached to the inner bottom surface of the placement groove 1.

[0038] The pressure block 301 is limited by the slot opening on the side wall of the placement slot 1 to improve the stability of the movement of the pressure block 301 and ensure that the pressure block 301 can accurately push out a single circuit breaker each time it works.

[0039] The wedge 201 is located at the end of the slider 202, and the perpendicular bisector of the wedge 201 is located in front of the contact area of ​​the two sliders 202.

[0040] The wedge 201 and the slider 202 fit together tightly, ensuring the production rhythm.
