Description

Technical Field

[0001] This invention relates to the field of molded case circuit breaker manufacturing, specifically to a circuit breaker housing assembly equipment and method. Background Technology

[0002] The outer shell of a molded case circuit breaker is made of plastic. The electronic components, switches, torsion springs, and other structures inside the circuit breaker are assembled between two circuit breaker shells. The production of molded case circuit breakers is carried out on intelligent automated assembly lines. The circuit breaker shells are generally loaded onto the automated assembly line by a vibratory feeder or a pusher plate feeding mechanism.

[0003] However, during the feeding of batches of housings by the push-plate feeding mechanism, since the housings have an outer smooth part (facing outward) and an inner mounting part (facing inward), the push-plate feeding mechanism cannot adjust the orientation of the housings during the upward conveying process. That is, it cannot be guaranteed that several housings will have the same orientation after feeding. This requires workers to flip some of the housings to ensure that housings with the same orientation can be directly picked up and installed by the robotic arm on the automated assembly line. However, the workload of manually flipping batches of housings is large, and the production line cannot be stopped. Workers cannot stop flipping the circuit breaker housings, resulting in a heavy physical burden on the workers. Summary of the Invention

A slot is provided inside the hopper. A swing block is elastically mounted on the upper end face of the second toothed plate via a pin and a torsion spring. The swing block always swings elastically towards the slot, and the maximum swing angle is ninety degrees. Two meshing transmission gears are also rotatably mounted on the upper end face of the mounting plate, and the two transmission gears mesh with the first toothed plate and the second toothed plate, respectively.

[0011] Preferably, the adsorption unit includes a plurality of first through holes that are equidistantly distributed in a straight line inside the support plate, and a suction pipe is fixedly connected to the bottom of each first through hole. A small suction pump is provided at the end of each suction pipe away from the support plate, and the small suction pump is fixed to the outside of the hopper. The end of each suction pipe away from the support plate is connected to the suction end of each small suction pump.

[0012] Preferably, the gas shut-off component includes a hollow cavity formed inside the support plate, the first through hole penetrating the hollow cavity, a sliding plate slidably mounted inside the hollow cavity, the reciprocating sliding direction of the sliding plate inside the hollow cavity being perpendicular to the connecting rod, a plurality of second through holes equidistantly distributed in a straight line inside the sliding plate, the second through holes and the first through holes having the same size and number, and an actuating element is also provided between the connecting rod and the sliding plate, the actuating element being used to adjust the position change of the sliding plate.

[0013] Preferably, the actuating element includes a gear differential fixed to the lower end face of the bearing plate, and the connecting rod is fixed to the input end of the gear differential. An adjusting gear is fixedly sleeved on the output end of the connecting rod. The lower end face of the sliding plate has a plurality of toothed grooves that are equidistantly distributed in a straight line, and the adjusting gear is movably meshed with the toothed grooves. The lower end face of the bearing plate has a straight groove corresponding to the periphery of each second through hole.

[0014] Preferably, there are two support frames, and two vertically distributed sliding rods are fixedly arranged between the two support frames. A sleeve block is slidably assembled between the two sliding rods, and the sleeve block is fixedly assembled with the hopper.

[0015] Preferably, the actuating component includes a limiting rod fixed inside the connecting plate.

The triangular plates are right-angled triangles with their inclined surfaces facing upwards.

In the initial state, the right-angled side of the triangular plate is fitted to the stop block, and the inclined surface of the triangular plate faces upwards.

[0016] A method for loading circuit breaker housings into an assembly equipment. The method includes the following steps:

[0017] S1. During the material loading stage, several circuit breaker housings that need to be assembled are stacked inside the hopper, and the drive unit, motor and small suction pump are started. The drive unit moves the connecting plate up and down back and forth, and the motor drives the conveyor belt to transport in one direction.

[0018] S2, Circuit breaker housing limiting stage: The small suction pump generates suction force in the first through hole through the suction pipe. When the smooth outer surface of the circuit breaker housing covers the upper end face of the first through hole, the negative pressure limiting of the circuit breaker housing can be completed.

[0019] S3. During the rising and transfer phase, as the circuit breaker housing, which is restricted by negative pressure, rises on the bearing plate, the second toothed plate and the first toothed plate move downwards simultaneously through the limiting effect of the swing block on the slot. That is, the bearing plate is tilted by pulling the connecting arm through the hinged seat plate. At the same time, under the action of the gas cut-off component, the circuit breaker housing is no longer subject to the suction force, so that the circuit breaker housing slides down to the upper end of the conveyor belt in a uniform direction.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This invention uses a lifting component to move the pusher block carrying the carrier plate upward. During the upward movement, the adsorption unit adsorbs and limits the smooth surface of the circuit breaker housing, ensuring that the carrier plate moves the circuit breaker housing upward with the smooth surface facing down and the assembly surface facing up. Under the action of the flipping unit, the carrier plate is tilted. While tilting, the carrier plate also touches the gas shut-off component, causing the circuit breaker housing to slide directly onto the transmission component for transfer.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figures 1-11 The diagram shows an assembly device for a circuit breaker housing, comprising: a hopper 1 in the shape of an inverted right trapezoid, with the upper port of the hopper 1 being open; a push block 11 slidably inserted into the bottom of the hopper 1; a bearing plate 12 hinged to the upper end face of the push block 11; the hinged part of the push block 11 and the bearing plate 12 facing the inclined surface of the hopper 1; a horizontal plate 38 on the outer side of the hopper 1; a support frame 2 at the bottom of the horizontal plate 38 for fixing and supporting; the horizontal plate 38 being located on the side close to the push block 11; a transmission component on the upper end face of the horizontal plate 38; and a lifting component between the push block 11 and the hopper 1, which is used to drive the push block 11 to move up and down.

[0036] It also includes: a flipping unit for adjusting the horizontal support plate 12 to an inclined position, and transferring the circuit breaker housing onto the transmission component through the inclined support plate 12;

[0037] The adsorption unit performs adsorption and positioning treatment on the circuit breaker housing placed on the upper end face of the support plate 12.

[0038] The transmission components include a folded plate 7 and a baffle 8 fixed to the upper end face of the horizontal plate 38. The folded plate 7 is located between the hopper 1 and the baffle 8, and the folded angle of the folded plate 7 faces the push block 11. Two transmission rollers are rotatably assembled between the folded plate 7 and the baffle 8, and a transmission belt 10 is driven between the two transmission rollers. A motor 13 is fixedly installed at the bottom of the horizontal plate 38, and the output end of the motor 13 and the end of one of the transmission rollers are driven by a synchronous gear and a synchronous toothed belt. When the push block 11 is raised, the bearing plate 12 tilts towards the transmission belt 10, which allows the circuit breaker housing on the upper end face of the bearing plate 12 to slide onto the baffle 8.

[0039] The lifting component includes two symmetrically distributed drive members 9 fixed on both sides of the hopper 1. The output ends of the drive members 9 face downwards. A connecting plate 14 is fixedly arranged between the output ends of the two drive members 9. A first tension spring 15 is fixedly arranged between the connecting plate 14 and the bottom of the push block 11. When the output ends of the two drive members 9 move up and down with the connecting plate 14, the push block 11 can move up and down inside the hopper 1 at the same time through the first tension spring 15. When the bearing plate 12 moves down to be flush with the lower inner surface of the hopper 1, it is the lowest position of the push block 11.

[0040] The flipping unit includes an assembly plate 37 fixed inside the push block 11. Two optical shafts 36 are slidably inserted inside the assembly plate 37. A hinged seat plate 35 is fixedly mounted on the top of the two optical shafts 36. A connecting rod 34 is rotatably mounted on the bottom of the bearing plate 12 away from the hinge. Two connecting arms 19 are hingedly mounted on the top of the hinged seat plate 35, and the other ends of the two connecting arms 19 are fixedly sleeved on the outside of the connecting rod 34. A support plate 20 is fixedly mounted on the bottom of the two optical shafts 36. A second tension spring 26 is fixedly mounted between the upper end face of the support plate 20 and the assembly plate 37. A first toothed plate 21 is fixedly mounted on the upper end face of the support plate 20, movably penetrating the assembly plate 37. A second toothed plate 22 is slidably fitted onto the end face of the assembly plate 37 away from the inclined surface of the hopper 1. Both the first toothed plate 21 and the second toothed plate 22 slide axially inside the assembly plate 37. 2. The end face away from the first toothed plate 21 slides and fits against the hopper 1, and the hopper 1 has an empty groove 24 inside. The upper end face of the second toothed plate 22 is elastically mounted with a swing block 23 through a pin and a torsion spring. The swing block 23 always swings elastically towards the empty groove 24, and the maximum swing angle is ninety degrees. The upper end face of the mounting plate 37 is also rotatably mounted with two meshing transmission gears 25, and the two transmission gears 25 also mesh with the first toothed plate 21 and the second toothed plate 22 respectively. When the push block 11 moves the mounting plate 37 upward, the swing block 23 will elastically embed into the empty groove 24. As the push block 11 and the mounting plate 37 continue to move upward, the second toothed plate 22 will slide downward inside the mounting plate 37, causing the first toothed plate 21 and the support plate 20 to slide downward with the optical axis 36 at the same time, so that the bearing plate 12 changes from a horizontal assembly to an inclined downward state.

[0041] The adsorption unit includes several first through holes 28 that are equidistantly distributed in a straight line inside the support plate 12. Each first through hole 28 has a suction pipe 27 fixedly connected to its bottom. Each suction pipe 27 has a small suction pump at its end away from the support plate 12. The small suction pump is fixed to the outside of the hopper 1. The end of each suction pipe 27 away from the support plate 12 is connected to the suction end of each small suction pump. When the small suction pump runs continuously, it can apply an adsorption force through the suction pipe 27 and the first through holes 28. When the smooth outer surface of the circuit breaker housing covers the end face of the first through hole 28, the circuit breaker housing can be restricted to the upper end face of the support plate 12.

[0042] Example 2: Please refer to Figures 7-9This embodiment is a further description of the first embodiment. An air-cutting component is also provided between the support plate 12 and the push block 11. The air-cutting component is used to cut off the adsorption force applied by the adsorption unit to the surface of the circuit breaker housing. The air-cutting component includes a hollow cavity opened inside the support plate 12. A first through hole 28 penetrates the hollow cavity. A sliding plate 30 is slidably assembled inside the hollow cavity. The reciprocating sliding direction of the sliding plate 30 inside the hollow cavity is perpendicular to the connecting rod 34. A number of second through holes 29 are opened inside the sliding plate 30 in a straight line and are equally spaced. The size and number of the second through holes 29 and the first through holes 28 are the same. An actuating element is also provided between the connecting rod 34 and the sliding plate 30. The actuating element is used to adjust the position change of the sliding plate 30. When the support plate 12 changes from a horizontal state to an inclined state, the rotation of the connecting rod 34 will cause the sliding plate 30 to slide through the actuating element.

[0043] The triggering element includes a gear differential 31 fixed to the lower end face of the support plate 12, and the connecting rod 34 is fixed to the input end of the gear differential 31. The output end of the connecting rod 34 is fixedly sleeved with an adjusting gear 32. The lower end face of the slide plate 30 is provided with a number of toothed grooves 33 that are distributed in a straight line at equal intervals. The adjusting gear 32 is movably meshed with the toothed grooves 33. The lower end face of the support plate 12 is provided with straight grooves corresponding to the periphery of each second through hole 29. The function of the straight grooves is to facilitate ventilation of the upper end face of the suction tube 27. The gear differential 31 is a gear speed increaser. When the connecting rod 34 rotates slightly, it can make the adjusting gear 32 rotate significantly, thereby adjusting the position of the slide plate 30 in the hollow cavity.

[0044] Example 3: Please refer to Figure 1 and Figure 2 This embodiment is a further explanation of other embodiments. There are two support frames 2. Two vertically distributed sliding rods 3 are fixedly arranged between the two support frames 2. A sleeve block 4 is slidably assembled between the two sliding rods 3, and the sleeve block 4 is fixedly assembled with the hopper 1. Two symmetrically distributed limiting plates 5 are also fixedly assembled between the two sliding rods 3. The sleeve block 4 is located between the two limiting plates 5. A spring 6 is also sleeved on the outer surface of the sliding rod 3, and the two ends of the spring 6 are fixed to the sleeve block 4 and the limiting plate 5 respectively. A toggle component is also provided between the connecting plate 14 and the support frame 2. Through the sliding assembly of the sleeve block 4 and the sliding rod 3, plus the action of the spring 6, the hopper 1 can elastically move between the two support frames 2.

[0045] The actuating component includes a limiting rod 16 fixed inside the connecting plate 14. One of the support frames 2 has several triangular plates 17 arranged in a straight line and equidistantly mounted on its outer wall via a rotating column and a coil spring. The triangular plates 17 are right-angled triangles with their inclined surfaces facing upwards. Each triangular plate 17 has a stop block 18 movably attached to its lower end face, and the stop block 18 is fixed to the support frame 2. In the initial state, the right-angled side of the triangular plate 17 is attached to the stop block 18, and the inclined surface of the triangular plate 17 faces upwards. When the connecting plate 14 moves downwards and touches the inclined surface of the triangular plate 17, it can cause the connecting plate 14, the driving component 9, and the hopper 1 to shift. After the limiting rod 16 separates from the triangular plate 17, the above structures can quickly and elastically reset, thereby causing the circuit breaker housing accumulated inside the hopper 1 to shake.

[0046] Working principle: (Reference) Figure 4 When a large number of circuit breaker housings accumulate inside the hopper 1, some of the housings will have their smooth surfaces facing downwards, i.e., the smooth surfaces will be in contact with the upper end face of the bearing plate 12 and cover the upper end face of the first through hole 28. Under the action of a small suction pump, a suction force can be applied to the smooth surfaces of the circuit breaker housings through the first through hole 28, which can limit the movement of the circuit breaker housings. At this time, the drive component 9 moves upwards with the connecting plate 14 and the push block 11, lifting the circuit breaker housings with their smooth surfaces facing downwards. The circuit breaker housing with the smooth surface facing up and the assembly surface facing down will slide down from the upper end of the support plate 12. During the continuous upward movement, the swing block 23 will elastically swing into the interior of the slot 24. With the continuous upward movement of the push block 11 and the cooperation of the two meshing transmission gears 25, the second toothed plate 22 and the first toothed plate 21 can move downward at the same time. At this time, when the optical shaft 36 moves downward with the hinged seat plate 35, it can pull the support plate 12 downward through the connecting arm 19, so that the support plate 12 is tilted.

[0047] During the downward pulling of the connecting arm 19 by the hinge plate 35, the connecting rod 34 will deflect, thereby causing the adjusting gear 32 to rotate. Through the meshing of the adjusting gear 32 and the tooth groove 33, the sliding plate 30 can slide, causing the second through hole 29 and the first through hole 28 to be misaligned. At this time, the suction pipe 27 can no longer apply negative pressure suction to the smooth surface of the circuit breaker housing through the first through hole 28, thereby causing the circuit breaker housing to slide down the inclined support plate 12 onto the conveyor belt 10, and the circuit breaker housing is transferred by the conveyor belt 10.

[0048] By feeding the circuit breaker housing in the above manner, it can be ensured that the circuit breaker housing moving onto the conveyor belt 10 has its smooth surface facing down and its assembly surface facing up. This avoids the need for workers to flip the circuit breaker housing during the transportation process, thereby saving manual operation and further improving assembly efficiency.

[0049] It is important to note that when the pusher 11 lowers the support plate 12 to its lowest point, i.e., when the upper surface of the support plate 12 is flush with the inner bottom surface of the hopper 1, the output end of the drive component 9 continues to move downward with the connecting plate 14, which will stretch the first tension spring 15. At the same time, the limiting rod 16 fixed on the connecting plate 14 will push the inclined surface of the triangular plate 17, thereby causing the hopper 1 and the overall external structure to shift laterally. When the limiting rod 16 continues to move downward and separates from the triangular plate 17, the hopper 1 will quickly and elastically reset, thereby causing the circuit breaker housing inside the hopper 1 to shake, so that the smooth surface of the circuit breaker housing is as close as possible to the upper surface of the support plate 12. By shaking, the position of the circuit breaker housing changes, which can improve the efficiency of the support plate 12 in adsorbing the smooth surface of the circuit breaker housing.
