Description

Technical Field

[0001] This application relates to the technical field of circuit breaker processing equipment, and in particular to a semi-automatic processing equipment for residual current circuit breakers. Background Technology

[0002] A residual current circuit breaker (RCCB) is an electrical safety protection device, also known as a residual current device, residual current switch, or residual current protection circuit breaker. An RCCB typically consists of a housing and an arc-extinguishing chamber housed within the housing. To guide the electric arc, the distance between the two side plates of the arc-extinguishing chamber gradually decreases. Therefore, the opening of the arc-extinguishing chamber needs to maintain a fixed orientation within the housing. The arc-extinguishing chamber must meet the orientation requirements when installed into the housing.

[0003] Currently, the installation of arc-extinguishing chambers into the housing is mostly done manually. Operators first visually identify the opening orientation of the arc-extinguishing chamber, then adjust its posture according to the positioning grooves, ribs, or markings on the housing, and finally press or snap it into the corresponding installation position in the housing. However, arc-extinguishing chambers are small in size, similar in shape, and their opening orientations are not significantly different. The manual identification and adjustment process relies on operator experience, and prolonged repetitive work can easily lead to visual fatigue and decreased attention, resulting in arc-extinguishing chambers being installed backwards, misaligned, or missing. If the arc-extinguishing chamber's opening orientation is incorrect, it will affect the introduction and extinguishing of the arc, reduce the breaking capacity and reliability of the residual current circuit breaker, and increase rework costs and defect rates. At the same time, manual assembly is inefficient and labor-intensive, making it difficult to meet the requirements of mass production and consistency. Summary of the Invention

[0004] To improve the low efficiency of manual assembly of arc-extinguishing chambers, this application provides a semi-automatic processing equipment for residual current circuit breakers.

[0005] This application provides a semi-automatic processing equipment for residual current circuit breakers, which adopts the following technical solution: A semi-automatic processing equipment for residual current circuit breakers includes a base, on which a housing transport module and an arc-extinguishing chamber installation module are provided. The housing transport module is used to transport and position the housing to the arc-extinguishing chamber installation station. The arc-extinguishing chamber installation module includes an arc-extinguishing chamber feeding structure and an arc-extinguishing chamber turning structure. The arc-extinguishing chamber feeding structure includes a vibratory feeder with a directional screening structure. The vibratory feeder is used to output the arc-extinguishing chambers one by one in a fixed orientation to the arc-extinguishing chamber turning structure. The arc-extinguishing chamber turning structure includes a turning moving component and a turning moving gripper. The turning moving component includes a transverse cylinder, a longitudinal cylinder, and a rotary motor. The transverse cylinder is mounted on the machine base, the longitudinal cylinder is mounted on the output shaft of the transverse cylinder, the rotary motor is mounted on the output shaft of the longitudinal cylinder, and the turning moving gripper is mounted on the rotary motor. The turning moving gripper is used to insert into the arc-extinguishing chamber and then open up to abut against the inner wall of the arc-extinguishing chamber to clamp the arc-extinguishing chamber. The transverse cylinder and the longitudinal cylinder are used to drive the steering and moving gripper to move between the arc-extinguishing chamber orientation structure and the arc-extinguishing chamber installation position. The rotary motor is used to drive the steering and moving gripper to rotate so as to install the arc-extinguishing chamber with a fixed orientation into the housing located at the arc-extinguishing chamber installation position at a fixed angle.

[0006] By adopting the above technical solution, the shell is automatically transported and positioned by the shell transport module. The arc-extinguishing chamber feeding structure uses a vibratory feeder with a directional screening structure to output the arc-extinguishing chambers one by one in a fixed orientation. Then, a horizontal cylinder, a vertical cylinder, and a rotary motor drive a steering gripper to move and rotate between the arc-extinguishing chamber orientation structure and the arc-extinguishing chamber installation station, thereby installing the arc-extinguishing chambers with a fixed orientation into the shell at a fixed angle. This structure replaces manual visual identification and manual adjustment of the arc-extinguishing chamber posture, which can reduce the risk of arc-extinguishing chambers being installed backwards or off-center, and improve assembly consistency and efficiency. At the same time, after the steering gripper inserts into the arc-extinguishing chamber, it opens up to abut against the inner wall to achieve clamping, which can adapt to the problems of small arc-extinguishing chamber size and easy slippage or obstruction of external clamping. The clamping is reliable and does not easily damage the appearance of the arc-extinguishing chamber.

[0007] Optionally, the arc-extinguishing chamber installation module further includes an arc-extinguishing chamber positioning structure. The arc-extinguishing chamber positioning structure includes an arc-extinguishing chamber positioning component and an arc-extinguishing chamber moving component. The arc-extinguishing chamber positioning component includes a positioning seat and two positioning cylinders. The positioning seat has a placement slot for placing the arc-extinguishing chamber. The placement slot has two adjacent side walls. The arc-extinguishing chamber moving component is used to move the arc-extinguishing chamber output from the vibratory feeder into the placement slot. The output ends of the two positioning cylinders extend into the placement slots and are respectively positioned opposite to the side walls of the two placement slots. When the arc-extinguishing chamber is located in the placement slot, the two positioning cylinders push the arc-extinguishing chamber against the corresponding side wall of the placement slot to achieve precise positioning of the arc-extinguishing chamber. The arc-extinguishing chamber steering structure is used to move the arc-extinguishing chamber in the placement slot into the housing.

[0008] By adopting the above technical solution, the arc-extinguishing chamber after the output of the vibratory feeder is precisely positioned again through the placement slot on the positioning seat and two positioning cylinders, so that the arc-extinguishing chamber is pushed against the two adjacent side walls of the placement slot, eliminating the incoming material posture error and the position offset during the movement, ensuring that the steering structure clamps the arc-extinguishing chamber in a fixed position and fixed posture, further improving the angle accuracy and assembly consistency of the arc-extinguishing chamber into the shell, and reducing material jamming, clamping deviation and poor installation.

[0009] Optionally, the arc-extinguishing chamber installation module 104 further includes an arc-extinguishing chamber pressing structure. The arc-extinguishing chamber pressing structure includes an arc-extinguishing chamber pressing component and an arc-extinguishing chamber pressing moving component. The arc-extinguishing chamber pressing component is used to press the arc-extinguishing chamber into the housing. The arc-extinguishing chamber pressing moving component is provided with a moving plate, and the moving plate has two moving slots. The base is provided with a mounting seat for placing the arc-extinguishing chamber, and the mounting seat has a mounting hole for the moving plate to pass through. The arc-extinguishing chamber pressing moving component is used to drive the moving plate to move, so that one of the two moving slots is aligned with the arc-extinguishing chamber turning structure, and the other is aligned with the arc-extinguishing chamber pressing component.

[0010] By adopting the above technical solution, an arc-extinguishing chamber pressing structure is added, and a moving plate with two moving slots is used to switch the arc-extinguishing chamber between the feeding position and the pressing position. After the arc-extinguishing chamber is put into the housing by the turning structure, the arc-extinguishing chamber pressing component can press the arc-extinguishing chamber to install it in place, avoiding the arc-extinguishing chamber from floating, not being pressed tightly, or not being stuck in place, thus improving assembly reliability and product quality stability. At the same time, the moving slot structure allows the feeding and pressing actions to avoid each other and be tightly connected.

[0011] Optionally, the arc-extinguishing chamber installation module further includes an arc-extinguishing chamber positioning structure, which includes a fixed base and a lifting assembly. The fixed base has a directional opening, the shape of which is adapted to the outer contour of the arc-extinguishing chamber with a fixed orientation, allowing only the arc-extinguishing chamber with a fixed orientation to pass through. The lifting assembly is used to drive the arc-extinguishing chamber at the vibratory feeder outlet to be lifted through the directional opening of the fixed base. The arc-extinguishing chamber steering structure is used to clamp the arc-extinguishing chamber at the directional opening of the fixed base.

[0012] By adopting the above technical solution, a directional opening adapted to the outer contour of the fixed-orientation arc-extinguishing chamber is opened on the fixed base, and the arc-extinguishing chamber is lifted through the directional opening using a lifting component. Only arc-extinguishing chambers with the fixed orientation can pass through, while arc-extinguishing chambers with incorrect orientation are blocked or cannot pass through. This achieves mechanical screening and positioning of the arc-extinguishing chamber orientation, further improving the consistency of the arc-extinguishing chamber posture, ensuring that the arc-extinguishing chamber clamped by the steering structure is in the correct orientation, and improving the installation quality. It also avoids the situation where the directional screening structure in the vibratory feeder makes a mistake when screening the arc-extinguishing chamber orientation, improves the stability of the correct orientation of the arc-extinguishing chamber, and allows the arc-extinguishing chamber to output in a fixed orientation.

[0013] Optionally, the fixing base includes a base and a fixing sleeve. The base has a through hole for the arc-extinguishing chamber to pass through. The directional opening is provided on the fixing sleeve and the base. The directional opening is only for the arc-extinguishing chamber with a fixed orientation to pass through. A magnetic attraction structure is provided between the base and the fixing sleeve. The magnetic attraction structure is used to fix the fixing sleeve to the base.

[0014] By adopting the above technical solution, the fixing base consists of a base and a fixing sleeve, with directional openings set on the fixing sleeve and the base, and the base and the fixing sleeve are fixed by a magnetic attraction structure. This ensures that the fixing sleeve is stably fixed on the base during operation, and also facilitates the disassembly, cleaning and replacement of the fixing sleeve, adapting to different specifications of arc-extinguishing chambers or maintenance needs, with a simple and reliable structure.

[0015] Optionally, the base is provided with an ejection assembly, the fixed sleeve is provided with a fixing rod, and the base is provided with a fixing groove for the fixing rod to be inserted. The fixing rod can be slidably set along the fixing groove. When the lifting assembly lifts the arc-extinguishing chamber with the wrong orientation, the arc-extinguishing chamber with the wrong orientation passes through the perforation of the base and pushes the fixed sleeve upward, so that the fixed sleeve overcomes the magnetic attraction force of the magnetic attraction structure and lifts relative to the base. At this time, the ejection assembly is used to push the arc-extinguishing chamber with the wrong orientation located between the fixed sleeve and the base out in the horizontal direction.

[0016] By adopting the above technical solution, the fixed sleeve is lifted when the incorrectly oriented arc-extinguishing chamber is raised through the sliding engagement of the fixed rod and the fixed groove. This allows the fixed sleeve to overcome the magnetic attraction and rise relative to the base, and the ejection component pushes the incorrectly oriented arc-extinguishing chamber out horizontally. This solution can automatically identify and reject incorrectly oriented arc-extinguishing chambers, preventing incorrect workpieces from getting stuck at the directional opening and causing machine downtime, thus improving the continuous operation capability and automation level of the equipment. The fixed rod and the fixed groove simultaneously restrict the movement direction of the fixed sleeve, ensuring accurate positioning after resetting.

[0017] Optionally, the fixing sleeve is provided with an ejection hole; when the arc-extinguishing chamber is located at the directional opening, the ejection component passes through the ejection hole and abuts against the arc-extinguishing chamber to press the arc-extinguishing chamber against the inner wall of the directional opening.

[0018] By adopting the above technical solution, a push-out hole is provided on the fixed sleeve. When the arc-extinguishing chamber is located at the directional opening, the push-out component can pass through the push-out hole to press the arc-extinguishing chamber against the inner wall of the directional opening. In this way, the arc-extinguishing chamber is temporarily pressed and positioned before the steering structure clamps it, preventing it from being displaced or deflected due to vibration, gravity, or contact of the grippers. This ensures accurate insertion and clamping positions of the grippers, further improving positioning reliability and installation accuracy. At the same time, the push-out component also has the function of expelling the incorrectly oriented arc-extinguishing chamber and pressing and positioning it correctly oriented towards the arc-extinguishing chamber, thus reusing the structure and reducing the number of parts.

[0019] Optionally, the lifting assembly includes a lifting cylinder and a lifting plate. The lifting cylinder is mounted on the base, and the lifting plate is mounted on the lifting cylinder. The lifting plate has a lifting ramp for supporting the arc-extinguishing chamber. The lifting ramp allows the arc-extinguishing chamber to slide in the base to the corresponding positioning opening.

[0020] By adopting the above technical solution, the lifting assembly uses a lifting cylinder and a lifting plate with a lifting ramp. The lifting ramp guides the arc-extinguishing chamber to slide to the position corresponding to the directional opening during the lifting process. This structure allows the arc-extinguishing chamber to complete alignment while being lifted, reducing the need for an independent centering mechanism. The operation is smooth, the structure is simple, and it improves the smoothness and positioning accuracy of the arc-extinguishing chamber as it passes through the directional opening.

[0021] In summary, this application includes at least one of the following beneficial technical effects: The shell is automatically transported and positioned by the shell transport module. The arc-extinguishing chamber feeding structure uses a vibratory feeder with a directional screening structure to output the arc-extinguishing chambers one by one in a fixed orientation. Then, a horizontal cylinder, a vertical cylinder, and a rotary motor drive a steering gripper to move and rotate between the arc-extinguishing chamber orientation structure and the arc-extinguishing chamber installation station, thereby installing the arc-extinguishing chambers with a fixed orientation into the shell at a fixed angle. This structure replaces manual visual identification and manual adjustment of the arc-extinguishing chamber posture, which can reduce the risk of arc-extinguishing chambers being installed backwards or off-center, and improve assembly consistency and efficiency. At the same time, after the steering gripper inserts into the arc-extinguishing chamber, it opens up to abut against the inner wall to achieve clamping, which can adapt to the problems of small arc-extinguishing chamber size and easy slippage or obstruction of external clamping. The clamping is reliable and does not easily damage the appearance of the arc-extinguishing chamber.

[0022] By utilizing the sliding engagement between the fixing rod and the fixing groove, the fixing sleeve is lifted when the incorrectly oriented arc-extinguishing chamber is raised. This causes the fixing sleeve to overcome the magnetic attraction and rise relative to the base, and the ejection assembly then pushes the incorrectly oriented arc-extinguishing chamber out horizontally. This solution can automatically identify and reject incorrectly oriented arc-extinguishing chambers, preventing incorrect workpieces from getting stuck at the directional opening and causing machine downtime, thus improving the continuous operation capability and automation level of the equipment. The fixing rod and the fixing groove simultaneously restrict the movement direction of the fixing sleeve, ensuring accurate positioning after resetting. Attached Figure Description

[0042] Reference Figure 4 and Figure 5 When an arc-extinguishing chamber is installed in the housing, the drive motor 136 drives the drive plate 140 to move, causing the moving slot 142 to move the housing within a small range. That is, the housing moves in the arc-extinguishing chamber installation position 112, so that the housing in the moving slot 142 is aligned with the arc-extinguishing chamber turning structure 116, so that the next arc-extinguishing chamber can be installed in the housing. At this time, the other moving slot 142 drives the housing to move within a small range, so that the other housing moves in the arc-extinguishing chamber fixing position 113, so that the housing in the other moving slot 142 is aligned with the arc-extinguishing chamber pressing assembly 134, so that the arc-extinguishing chamber pressing assembly 134 can press and fix the arc-extinguishing chamber.

[0043] Reference Figure 4 and Figure 5 When the arc-extinguishing chamber is installed, the drive motor 136 drives the drive plate 140 to move, and the moving plate 141 moves the arc-extinguishing chamber to move the housing from the arc-extinguishing chamber installation position 112 to the arc-extinguishing chamber fixing position 113, so that the arc-extinguishing chamber can be pressed and fixed by the subsequent arc-extinguishing chamber pressing assembly 134.

A through hole 150 is provided on the base 148 for the arc-extinguishing chamber to pass through, with the through hole 150 facing the vibratory feeder outlet. A positioning opening 151 is provided on the base 148 for the arc-extinguishing chamber to pass through. An inclined surface 152 is provided on the side of the base 148, allowing the arc-extinguishing chamber at the positioning opening 151 to slide along the inclined surface 152, preventing the incorrectly oriented arc-extinguishing chamber from getting stuck in the base 148. A positioning opening 151 is also provided inside the fixed sleeve 149, allowing only the arc-extinguishing chamber with the correct orientation to pass through. The shape of the positioning opening 151 is adapted to the outer contour of the correctly oriented arc-extinguishing chamber.

[0047] Reference Figure 8 A magnetic attraction structure 153 is provided between the fixing sleeve 149 and the base 148. The magnetic attraction structure 153 includes a first magnet 154 and a second magnet 155. The first magnet 154 is fixedly connected to the base 148, and the second magnet 155 is fixedly connected to the fixing sleeve 149. The first magnet 154 attracts the second magnet 155 to achieve fixation between the fixing sleeve 149 and the base 148. A fixing rod 156 is fixedly connected to the fixing sleeve 149, and a fixing groove 157 is provided on the base 148 for the fixing rod 156 to pass through, allowing the fixing rod 156 to slide within the fixing groove 157.

[0048] Reference Figure 8 The base 100 is equipped with an ejection assembly 158, which includes an ejection cylinder. An ejection hole 159 is provided on the side of the fixed sleeve 149, through which the output end of the ejection cylinder passes, and extending to the end face of the fixed sleeve 149 facing the base 148. A lifting ramp 160 is provided on the lifting plate 147, allowing the arc-extinguishing chamber to slide on it. The distance between the lifting ramp 160 and the ground gradually decreases along the direction from the ejection cylinder to the fixed sleeve 149, allowing the arc-extinguishing chamber to slide along the lifting ramp 160 so that it can smoothly abut against the inner wall of the fixed base 144.

[0049] Reference Figure 8When the arc-extinguishing chamber is in the correct orientation, the lifting cylinder 146 is activated, and the lifting plate 147 lifts the arc-extinguishing chamber, allowing it to slide along the inclined surface 152 and along the lifting inclined surface 160. Since the arc-extinguishing chamber is in the correct orientation, it can slide to the positioning opening 151 inside the fixed sleeve 149. Then, the cylinder is pushed out to abut against the arc-extinguishing chamber, allowing it to abut against the inner wall of the fixed sleeve 149, thus achieving precise positioning of the arc-extinguishing chamber.

[0050] Reference Figure 8 When the arc-extinguishing chamber is in the wrong orientation, the lifting cylinder 146 is activated, and the lifting plate 147 lifts the arc-extinguishing chamber, allowing it to slide along the inclined surface 152 and along the lifting inclined surface 160. Since the arc-extinguishing chamber is in the wrong orientation, it abuts against the end face of the fixing sleeve 149 facing the base 148, allowing the arc-extinguishing chamber to lift the fixing sleeve 149. The fixing sleeve 149 can then be lifted along the length of the fixing rod 156, so that the arc-extinguishing chamber can be positioned between the fixing sleeve 149 and the base 148. Then, the cylinder pushes the arc-extinguishing chamber to move, allowing it to disengage from the fixing seat 144 between the fixing sleeve 149 and the base 148, thus realizing the unloading of the arc-extinguishing chamber with the wrong orientation.

[0051] The implementation principle of Example 2 is as follows: When the arc-extinguishing chamber is in the correct orientation, the lifting cylinder 146 is activated, and the lifting plate 147 drives the arc-extinguishing chamber to be lifted, allowing the arc-extinguishing chamber to slide along the inclined surface 152 and along the lifting inclined surface 160. Since the arc-extinguishing chamber is in the correct orientation, it can slide to the positioning opening 151 inside the fixed sleeve 149. Then, the cylinder is pushed out to abut against the arc-extinguishing chamber, allowing the arc-extinguishing chamber to abut against the inner wall of the fixed sleeve 149, thereby achieving precise positioning of the arc-extinguishing chamber.
