Description

Technical Field

[0001] The invention relates to the technical field related to electrical component feeding, and in particular to an electrical component positioning and feeding device. Background Art

[0002] Electrical components and electronic components are both part of electrical engineering, but there are clear differences between them. Electrical components refer to electromechanical control components, which are mainly used to transmit and control electrical energy in high-voltage and high-current power system environments, while electronic components refer to pure circuit line components, which are mainly used to process electrical signals in low-voltage and low-current electronic circuit environments.

[0003] Common electrical components in power equipment include circuit breakers, relays, transformers and switches. As for circuit breakers, their function is to cut off and connect load circuits, as well as cut off fault circuits. Circuit breakers require loading operations during production.

[0004] After searching the invention patent with patent number CN116430215B, a circuit breaker processing, assembly and detection device is disclosed, including a base, a lifting mechanism is arranged on the base, a support frame is connected to the lifting mechanism, a limiting mechanism is arranged on the support frame, which is used to clamp and fix the circuit breaker, a current detection mechanism is connected to the limiting mechanism, and a switch detection mechanism is arranged on the support frame. The circuit breaker processing, assembly and detection device can clamp and fix the circuit breaker through the limiting mechanism, and can automatically connect the detection circuit to the circuit breaker during the clamping and fixing process, effectively improving the wiring efficiency, and limiting the circuit breaker through the limiting mechanism can effectively prevent the detection circuit from being loosened due to vibration and operation, etc., ensuring the stability of the detection, and making the detection result more reliable.

[0005] The electrical component circuit breaker feeding device used in the above patents and prior art background still has certain disadvantages, such as:

[0006] 1. The existing circuit breaker feeding device is only used for clamping and fixing the circuit breaker, and then feeding and conveying the circuit breaker. Its function is relatively single, and it only meets the use requirements of circuit breaker feeding and conveying on the production line, and cannot simultaneously realize the qualified detection of the circuit breaker during the feeding process;

[0007] 2.

DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] See also Figure 1-10 The present invention provides a technical solution: an electrical component positioning and feeding device, including a frame 1, an expansion fixing mechanism 2 and an adjustable detection mechanism 4.

[0047] The electrical component positioning and loading device is mainly used for loading and conveying electrical component circuit breakers. Circuit breakers are divided into one pole to four poles, where the number of poles refers to the number of wires that cut off the circuit. The two connection points of the wires in the circuit breaker are respectively placed at both ends of the circuit breaker. The wire connection point in the circuit breaker is composed of a wire plug hole and a bolt locking hole. The bolt locking hole is set toward the front, and the wire plug hole is set toward the side, and the two are in a vertically connected state.

[0048] Before using the electrical component positioning and feeding device, it is necessary to add or reduce the corresponding number of fixed detection structures according to the different pole numbers of the circuit breaker, and Figure 1 , Figure 2 and Figure 3 As shown, since the two left and right expansion type fixing mechanisms 2, the two left and right adjustment type detection mechanisms 4 and the carrier plate 3 are combined to form a set of fixed detection structures, which are used to fix and detect the primary point circuit breaker, the number of poles of the circuit breaker to be transported is matched, and multiple sets of fixed detection structures are arranged at equal intervals below the rack 1;

[0049] Since an open groove is provided in the middle of the lower side wall of the frame 1, and since the longitudinal section of the carrier plate 3 is in a "convex" shape, after placement, the narrow portion thereof is movably clamped in the groove in the frame 1, and the wide portion is attached to the lower side wall of the frame 1, and is arranged in an active positioning state. According to the position of the wire connection in the circuit breaker, the carrier plate 3 is slid on the lower side wall of the frame 1 to adjust the position to correspond to the wire connection in the circuit breaker;

[0050] Since the left and right side frames of the frame 1 are provided with through adjustment long grooves, and since the sliding connection between the carrier plate 3 and the frame 1 is provided with fixing bolts, the fixing bolts in the carrier plate 3 are symmetrically arranged about its vertical center axis, wherein the fixing bolts are movably inserted through the adjustment long grooves in the frame 1 after being arranged, and are threadedly fixed on the plate body of the carrier plate 3. After the carrier plate 3 completes the position sliding adjustment, the fixing bolts are screwed to press against the frame body in the frame 1, so as to lock the carrier plate 3 and the frame 1.

[0051] Before using the electrical component positioning and feeding device, it is necessary to adjust the spacing between the two expansion fixing mechanisms 2 according to the spacing between the two bolt locking holes in the circuit breaker, so that the expansion fixing mechanism 2 can be freely adjusted to be suitable for circuit breakers of different specifications and sizes. Figure 2 and Figure 3 As shown, the expansion fixing mechanism 2 is arranged symmetrically with respect to the vertical center axis of the carrier plate 3. Since the lower side wall of the carrier plate 3 is provided with a through wedge-shaped limiting groove, and since the guide plate 501 is arranged in a wedge-shaped structure and is arranged horizontally at the upper end of the tube shell 5 in an integrated structure, and is adapted to the wedge-shaped limiting groove in the carrier plate 3, the guide plate 501 is movably inserted into the wedge-shaped limiting groove in the carrier plate 3 after being placed, and is arranged in a movable positioning state. The tube shell 5 is slid on the carrier plate 3 with the assistance of the guide plate 501, so that the expansion fixing mechanism 2 slides on the carrier plate 3 to adjust the position, and the two expansion fixing mechanisms 2 correspond to the two bolt locking holes in the circuit breaker respectively;

[0052] Since a through-going adjustment slot is provided in the middle of the guide plate 501, and a fixing bolt is provided at the sliding connection between the guide plate 501 and the carrier plate 3, the fixing bolt in the guide plate 501 is movably inserted through the adjustment slot after being installed, and is threadedly fixed to the wall of the wedge-shaped limiting slot in the carrier plate 3. After the expansion fixing mechanism 2 completes the position sliding adjustment, the sliding of the guide plate 501 is completed, and the fixing bolt is pressed against the plate body of the guide plate 501 by screwing it, so as to lock the guide plate 501 and the carrier plate 3, thereby completing the locking of the expansion fixing mechanism 2.

[0053] Before using the electrical component positioning and feeding device, the position of the adjustable detection mechanism 4 needs to be adjusted according to the position of the wire jack in the circuit breaker, so that the adjustable detection mechanism 4 can be freely adjusted according to circuit breakers of different specifications and sizes. Figure 2 , Figure 8 and Fig. 9 As shown, the bracket 11 is arranged in an "H"-shaped structure. Since the frame walls on the front and rear sides of the upper frame cavity of the bracket 11 are provided with limiting grooves, and since the adjustment seat 12 is composed of a block body and a tube body, the front and rear sides of the block body are provided with positioning strips of an integrated structure. After the adjustment seat 12 is placed, the block body is movably clamped in the upper frame cavity of the bracket 11, and the two positioning strips of the block body are movably clamped in the two limiting grooves in the bracket 11, respectively, and are arranged in an active positioning state. The adjustment seat 12 is slid in the upper frame cavity of the bracket 11, so that the adjustment seat 12 drives the detection rod frame 13 to slide and adjust synchronously;

[0054] Since the tube body portion in the adjustment seat 12 is arranged in a through state, and since the detection rod frame 13 is in an "L"-shaped structure, after being placed, the longitudinal rod body movably penetrates the tube body portion in the adjustment seat 12 and extends outward, and is arranged in an active positioning state. The detection rod frame 13 is slid in the tube body portion in the adjustment seat 12 to adjust the position, so that after the adjustable detection mechanism 4 is turned over and unfolded, the transverse rod body in the detection rod frame 13 is arranged in a horizontal state, corresponding to the wire jack in the circuit breaker;

[0055] Since the front and rear frames of the upper section of the bracket 11 are both provided with through-state adjustment long grooves, and since a fixing bolt is provided at the sliding connection between the adjustment seat 12 and the bracket 11, a fixing bolt is provided at the middle of the two positioning strips of the block part of the adjustment seat 12, wherein the fixing bolt is movably inserted through the adjustment long groove in the bracket 11 after being arranged, and is threadedly fixed on the positioning strip of the block part. After the adjustment seat 12 drives the detection rod frame 13 to complete the sliding adjustment, the fixing bolt is pressed against the frame of the bracket 11 by screwing, so as to lock the adjustment seat 12 with the bracket 11;

[0056] Since a fixing bolt is provided at the sliding connection between the detection rod frame 13 and the adjustment seat 12, the fixing bolt in the detection rod frame 13 is movably inserted through the tube body portion in the adjustment seat 12 after being installed, and is threadedly fixed on the tube body portion. After the detection rod frame 13 completes the sliding adjustment, the fixing bolt is screwed to press against the longitudinal rod body in the detection rod frame 13, which is used to lock the detection rod frame 13 and the adjustment seat 12.

[0057] Before using the electrical component positioning and feeding device, the conductive head 16 needs to be replaced according to the specifications of the wire jack in the circuit breaker. Fig.10 As shown, the conductive head 16 is threadedly fixed to the head end of the second piston column 15, and can be disassembled and replaced by rotating the conductive head 16.

[0058] When the electrical component positioning and feeding device is in use, the expansion type fixing mechanism 2 is arranged in a vertical downward state after being placed, and it is automatically fixed by docking with the bolt locking hole in the circuit breaker in an expansion manner. The adjustable detection mechanism 4 is initially in a folded state, and it is linked to the expansion type fixing mechanism 2. After it is turned over and unfolded, the transverse rod body in the detection rod frame 13 is arranged in a horizontal state, corresponding to the wire jack in the circuit breaker, and is used for synchronous detection of power-on qualification after the circuit breaker is fixed. The middle part of the upper side wall of the frame 1 is fixedly connected with the execution end of the mechanical arm by bolts, and is arranged in a horizontal state, and is driven and moved by the mechanical arm for feeding and conveying (the above-mentioned mechanical arm is a prior art and is not described in the drawings of the specification);

[0059] The circuit breaker is automatically fixed by the expansion fixing mechanism 2. Specifically, according to the attached Figure 2 , Figure 4 , Figure 5 , Figure 6and Figure 7 As shown, the tube shell 5 is arranged in a vertical state after being placed, and four clamping claws 8 are arranged in a circular array with the center of the tube shell 5 as the center, which is arranged in a quarter-conical structure. The four clamping claws 8 in the tube shell 5 are combined to form a conical structure. When the expansion fixing mechanism 2 is connected with the bolt locking hole in the circuit breaker, the clamping claw 8 is positioned and inserted into the bolt locking hole in the circuit breaker, and the setting of the conical structure ensures the accurate insertion of the clamping claw 8;

[0060] Since the shell cavity wall at the upper end of the tube shell 5 is provided with a first cylinder cavity 502, the first cylinder cavity 502 is connected to the air supply device through a spring hose (the above-mentioned air supply device is a prior art and is not described in the drawings of the specification), and since the upper end of the first piston column 9 is fixedly sleeved with sealing rings at equal intervals, wherein the sealing rings are tightly fitted with the cavity wall of the first cylinder cavity 502, and the sealing plug is placed in the first cylinder cavity 502, and air is supplied to the first cylinder cavity 502 through the air supply device, so that the first piston column 9 extends and slides in the first cylinder cavity 502;

[0061] Since the linkage column 6 is arranged in a nail-shaped structure, it is movably clamped in the middle shell cavity of the tube shell 5 after being installed, and is arranged in an active positioning state. Since the first piston column 9 is arranged on the same vertical central axis as the linkage column 6, its lower end is clamped and fixedly connected to the upper side wall of the nail head part of the linkage column 6 by bolts, the first piston column 9 is driven to slide and extend, and then drives the linkage column 6 to move synchronously, so that the linkage column 6 slides downward in the middle shell cavity of the tube shell 5;

[0062] Since the nail head in the linkage column 6 is separately provided with a spring bin, a first spring member 7 is installed at the connection between the linkage column 6 and the tube shell 5. After being installed, the first spring member 7 is movably sleeved on the nail rod part in the linkage column 6, one end of which is movably inserted in the spring bin in the linkage column 6 and pressed against the bin wall, and the other end of which is pressed against the middle shell cavity wall of the tube shell 5. After the linkage column 6 is driven to slide downward, the first spring member 7 is squeezed and elastically deformed;

[0063] Since the lower end of the rod body part of the linkage column 6 is provided with a pushing portion 602 of an integrated structure, the two are located on the same vertical central axis. After the linkage column 6 is installed, the lower end of the nail rod part thereof is movably inserted into the lower shell cavity of the tube shell 5 together with the pushing portion 602. After the linkage column 6 is driven to slide downward, the pushing portion 602 and the linkage column 6 form a synchronous sliding structure, so that the pushing portion 602 slides downward in the lower shell cavity of the tube shell 5.

[0064] Since the pushing portion 602 is in the form of a circular cone-shaped structure with the opening facing downward, and since the upper end of the clamping jaw member 8 is provided with a "V"-shaped frame portion 801 of an integrated structure, the "V"-shaped frame portion 801 is divided into two parts, an outward frame body and an inward frame body, wherein the outward frame body is arranged in an inclined state, adapted to the conical cylindrical inclined groove wall of the pushing portion 602, and since the outward frame body in the "V"-shaped frame portion 801 and the conical cylindrical inclined groove wall of the pushing portion 602 are pressed and fitted, after the pushing portion 602 slides downward, the pushing portion 602 pushes the outward frame body in the "V"-shaped frame portion 801, thereby driving the clamping jaw member 8 to move;

[0065] Since the upper end of the clamping jaw 8 is inserted and rotatably connected with a shaft column, after being placed, the upper end thereof is movably inserted and movably clamped in the lower shell cavity of the tube shell 5, and the shaft column is inserted and fixedly connected to the wall of the lower shell cavity of the tube shell 5, and is arranged in a movable positioning state, and since the clamping jaw 8 is arranged in a circular array with the center of the tube shell 5 as the center of the circle, and a rubber pad is clamped and glued and fixed on the outer side thereof, the clamping jaw 8 is driven to turn over and unfold at the lower end of the lower shell cavity of the tube shell 5, so that the clamping jaw 8 together with the rubber pad is connected to the bolt locking hole in the circuit breaker in a pressing and fitting manner, and the clamping jaw 8 is expanded to complete the fixation between the clamping jaw 8 and the bolt locking hole in the circuit breaker, that is, the circuit breaker is picked up and fixed;

[0066] Since the inner frame of the "V"-shaped frame part 801 is arranged in an inclined state, a second spring member 10 is installed at the connection between the "V"-shaped frame part 801 and the tube shell 5, and since the upper end of the second spring member 10 is fixedly connected to a cylindrical end head, and the lower end thereof is fixedly connected to a bottom cover, after the second spring member 10 is arranged, the end head thereof is movably inserted into the middle groove cavity of the lower shell cavity of the tube shell 5, and the bottom cover is clamped and fixedly connected to the lower shell cavity wall of the tube shell 5 by bolts. When the clamping claw member 8 is driven to flip and unfold, the inner frame of the "V"-shaped frame part 801 is connected to the end head of the second spring member 10 in a pressing and fitting manner, and the end head of the second spring member 10 is pushed, so that the end head thereof slides in the lower shell cavity of the tube shell 5, and the second spring member 10 is elastically deformed by being squeezed;

[0067] According to the above, when releasing the fixing operation of the circuit breaker, air is evacuated to the first cylinder chamber 502 through the air supply device, and the elastic deformation of the first spring member 7 is used to reset, so that the first piston column 9 drives the linkage column 6 to reset and slide upward. After the pushing portion 602 loses its pushing force on the outer frame in the "V"-shaped frame portion 801, the elastic deformation of the second spring member 10 is used to reset, so that the clamping claw member 8 is flipped and reset, thereby releasing the expansion fixation of the bolt locking hole in the circuit breaker.

[0068] The circuit breaker is tested synchronously by the adjustable detection mechanism 4. Figure 2 , Figure 4 , Figure 8 , Fig. 9 and Fig.10 As shown, a through-state slide groove is provided in the inner shell wall of the middle shell cavity of the tube shell 5. Since the "U"-shaped seat 601 is in a vertical state after being placed, it is fixedly connected to the inner side wall of the nail head part of the linkage column 6 by bolts, and its movable clamp is arranged in the slide groove of the tube shell 5. When the linkage column 6 is driven to slide downward, it drives the "U"-shaped seat 601 to slide downward synchronously along the slide groove in the tube shell 5.

[0069] Since a pin is inserted and fixedly connected to the frame wall of the "U"-shaped seat 601, and since a through-shaped slide groove is provided on the toggle block 14, after being installed, the pin in the "U"-shaped seat 601 is movably inserted through the slide groove in the toggle block 14, and is arranged in an inclined state with the "U"-shaped seat 601, when the "U"-shaped seat 601 slides downward, the pin in the "U"-shaped seat 601 slides on the toggle block 14, and the toggle block 14 is driven to move through the sliding cooperation of the two;

[0070] Since both the front and rear sides of the slide slot in the tube shell 5 are provided with a connecting seat of an integrated structure, wherein a shaft column is inserted and rotatably connected to the connecting seat, and since the toggle block 14 is sleeved and fixedly connected to the middle part of the shaft column of the connecting seat in the tube shell 5 by bolts after being installed, the toggle block 14 drives the shaft column to rotate on the connecting seat in the tube shell 5 after being driven;

[0071] Since the bracket 11 is arranged in an inclined state after being placed, the tube shell 5 is inserted into the lower frame cavity of the bracket 11 in an active state, and the front and rear frames at the lower end thereof are respectively sleeved and fixedly connected to the two ends of the shaft column in the tube shell 5 by bolts, the bracket 11 and the toggle block 14 form a synchronous rotation structure, and after the toggle block 14 is driven, the bracket 11 is turned over and unfolded on the connecting seat in the tube shell 5 with the assistance of the shaft column, and the bracket 11 drives the detection rod frame 13 to turn over and unfold, and the horizontal rod body in the detection rod frame 13 corresponds to the wire jack in the circuit breaker;

[0072] Since an air passage is provided in the longitudinal rod body of the detection rod frame 13, wherein the air passage is connected to the air supply device through a spring hose, a second cylinder chamber 1301 is provided in the transverse rod body of the detection rod frame 13, and the second cylinder chamber 1301 is connected to the air passage in the detection rod frame 13.
