Description

Technical Field

[0001] This invention relates to the field of electrical component technology, and more specifically, to an automatic assembly machine for an arc-damping plate of a terminal block assembly. Background Technology

[0002] A terminal block assembly is a wiring structure used in electrical equipment such as circuit breakers or residual current devices. Its structure typically includes a square-framed terminal block, a terminal screw with a washer that screws into the terminal block, a clamp inserted into the screw, and a terminal piece inserted into the terminal block below the terminal screw. Depending on user requirements, some existing terminal block assemblies may also have an arc-shielding plate. When an arc-shielding plate is installed, the terminal piece needs to be Z-shaped to clamp the arc-shielding plate onto the terminal block. For stability, the terminal piece also has protrusions that insert into holes in the arc-shielding plate for positioning. Therefore, during installation, a sufficiently large gap must be maintained between the terminal piece and the terminal block to facilitate the insertion of the arc-shielding plate. However, a large gap can lead to instability and hinder automation. Summary of the Invention

[0003] In summary, to overcome the shortcomings of the prior art, the present invention provides an automatic assembly machine for the arc-damping plate of a terminal block assembly.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an automatic assembly machine for an arc-blocking plate of a terminal block assembly, comprising a conveying device, a first feeding device, and a discharging device, wherein a second feeding device is provided between the first feeding device and the discharging device, the conveying device is provided with a mounting base, the first feeding device and the second feeding device respectively feed the terminal block and the arc-blocking plate into the mounting base, the mounting base is provided with a mounting groove, a connecting socket communicating with the mounting groove is provided on one side of the mounting base, a clamping member is provided on each side of the connecting socket, and the mounting base is provided with a driving member that applies a force toward the connecting socket to the clamping member.

[0005] Furthermore, the mounting base is provided with a sliding groove adapted to the clamping member, and the driving member is a spring, which is located on the side of the sliding groove facing away from the connection socket.

[0006] Furthermore, the mounting base is provided with connecting blocks on both sides, the connecting blocks are detachably connected to the mounting base, and the sliding groove is provided through the side of the mounting base.

[0007] Furthermore, the connecting block is L-shaped, and there is a gap between the connecting block and the position where the sliding groove is provided on the mounting base. Both the connecting block and the clamping member have a reset groove adapted to the driving member on the side facing each other.

[0008] Furthermore, a gap is provided between the two clamping members, and a limiting block is provided on the side of the clamping member facing away from the sliding groove.

[0009] Furthermore, the opening on the side of the connector facing away from the mounting groove and the end face of the clamping member facing the connector are flared outwards.

[0010] Furthermore, the second feeding device includes a vibratory feeder assembly, a pusher assembly, a steering wheel, a steering block, and a feeding robot. The steering block is provided with a steering socket adapted to the arc-blocking plate. The pusher assembly sends the arc-blocking plate to the steering socket. The steering wheel drives the steering block to rotate. The feeding robot moves the arc-blocking plate on the steering block into the mounting groove.

[0011] Furthermore, a stabilizing block is provided inside the steering socket, and the stabilizing block is reset to face the steering socket.

[0012] Furthermore, a top plate mechanism is provided between the second feeding device and the unloading device. The top plate mechanism includes a telescopic member and a top rod. The telescopic member controls the top rod to move toward the connecting socket.

[0013] Furthermore, it also includes a screw-tightening mechanism located above the top plate mechanism.

[0014] The beneficial effects of this application are as follows: During installation, the first feeding device does not fully insert the connector when installing it; there is a gap between its vertical plate and the connector. After it moves to the position of the second feeding device, the second feeding device can insert and install the arc-blocking plate. The semi-finished connector assembly can be placed in the mounting slot, and then the connector is used by the first feeding device to insert the connector. If the connector is not fully inserted, its position is unstable and may move during the conveying process. The clamping parts on both sides will clamp the connector from both sides under the action of the driving part to prevent its displacement and will not affect the installation of the arc-blocking plate. The first feeding device can be composed of a vibratory feeder, a feeder, a mounting frame adapted to the shape of various parts, and a robot. The vibratory feeder vibrates the parts onto the feeder, which then conveys them to the mounting frame position, and the robot moves them to the mounting seat. The feeder can be a linear vibrating type or a cylinder blowing type. The unloading device can be just a robot. Attached Figure Description

[0023] This specific embodiment is merely an explanation of the present embodiment and is not intended to limit the present embodiment. After reading this specification, those skilled in the art can make modifications to the present embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present embodiment.

[0024] Referring to the accompanying drawings, the present invention provides the following technical solution: an automatic assembly machine for an arc-blocking plate of a terminal block assembly, comprising a conveying device 2, a first feeding device 3, and a discharging device 4, wherein a second feeding device 5 is provided between the first feeding device 3 and the discharging device 4, the conveying device 2 is provided with a mounting base 501, the first feeding device 3 and the second feeding device 5 respectively feed the terminal block 104 and the arc-blocking plate 105 into the mounting base 501, the mounting base 501 is provided with a mounting groove 5011, a connecting socket 5012 communicating with the mounting groove 5011 is provided on one side of the mounting base 501, a clamping member 5013 is provided on each side of the connecting socket 5012, and the mounting base 501 is provided with a driving member 5014 that applies a force to the clamping member 5013 toward the connecting socket 5012.

[0025] With this configuration, when the first feeding device 3 installs the connector 104, it will not fully insert it. There will be a gap between its vertical plate and the connector 101. This allows the second feeding device 5 to insert the arc-damping plate 105 after the connector 104 is moved to its position. The semi-finished connector assembly 1 can be placed in the mounting slot 5011, and then the connector 5012 is used by the first feeding device 3 to insert the connector 104. If the connector 104 is not fully inserted, its position is unstable, and it may cause problems during transport. The clamping parts 5013 on both sides will clamp the wiring piece 104 from both sides under the action of the driving part 5014 to prevent it from shifting and will not affect the installation of the arc-blocking plate 105. The first feeding device 3 can be composed of a vibratory plate, a feeder, a mounting frame adapted to the shape of various parts, and a robot. The vibratory plate vibrates the parts onto the feeder, which then transports them to the mounting frame position, and the robot moves them to the mounting seat 501. The feeder can be a linear vibration type or a cylinder blowing type. The unloading device 4 can be made using only a robot.

[0026] In a preferred embodiment, the mounting base 501 is provided with a sliding groove 5015 adapted to the clamping member 5013, and the driving member 5014 is a spring, which is located on the side of the sliding groove 5015 facing away from the connecting socket 5012.

[0027] With this configuration, the spring can continuously apply force to the clamping member 5013 without power output, which saves more costs. Under the action of the spring, the clamping member 5013 will push against the terminal piece 104 located in the connection socket 5012 in the sliding groove 5015 and clamp it from both sides.

[0028] In a preferred embodiment, the sliding groove 5015 penetrates the top surface of the mounting base 501.

[0029] With this configuration, the clamping member 5013 can be set higher to accommodate the taller wiring piece 104. At the same time, the cross-sections of the sliding groove 5015 and the clamping member 5013 can be set in a convex shape to prevent them from popping out from above.

[0030] In this preferred embodiment, the mounting base 501 is provided with connecting blocks 5016 on both sides, the connecting blocks 5016 are detachably connected to the mounting base 501, and the sliding groove 5015 is provided through the side of the mounting base 501.

[0031] With this setup, the clamping component 5013 and the driving component 5014 can be inserted first, and then the connecting block 5016 can be installed. This makes installation convenient. The connecting block 5016 can be connected to the mounting base 501 using conventional methods such as bolts or snap-fits.

[0032] In this preferred embodiment, the connecting block 5016 is L-shaped, and the position gap between the connecting block 5016 and the sliding groove 5015 on the mounting base 501 is set. Both the connecting block 5016 and the clamping member 5013 have a reset groove 50161 adapted to the driving member 5014 on the side facing each other.

[0033] With this design, the L-shape can indirectly increase the sliding distance of the clamping member 5013, and the reset groove 50161 can stabilize the spring and prevent it from flying around.

[0034] The above settings are not limited. The reset groove 50161 can be set on only one part, or it can be set as a positioning rod structure for positioning.

[0035] In this preferred embodiment, the clamping member 5013 is provided with a limiting setting, and a gap is provided between the two clamping members 5013.

[0036] With this configuration, the gap between the two clamps 5013 makes it easier to install the connector 104.

[0037] In a preferred embodiment, the clamping member 5013 is provided with a limiting block 50131 on the side facing away from the sliding groove 5015.

[0038] With this configuration, the limiting block 50131 will abut against the opening of the sliding groove 5015, preventing it from being pushed too far. The structure is simple, and the gap of the L-shaped connecting block 5016 allows for easy setting of the limiting block 50131 without interference.

[0039] In this preferred embodiment, the opening on the side of the connecting socket 5012 facing away from the mounting groove 5011 and the end face of the clamping member 5013 facing the connecting socket 5012 are flared outwards.

[0040] With this setup, even if the connector 104 is slightly off-center after the flare is set, it can still be inserted along the flare, making the installation more stable.

[0041] In a preferred embodiment, the second feeding device 5 includes a vibratory feeder assembly 502, a pusher assembly 503, a steering wheel 504, a steering block 505, and a feeding robot 506. The steering block 505 is provided with a steering socket 5051 adapted to the arc-blocking plate 105. The pusher assembly 503 sends the arc-blocking plate 105 to the steering socket 5051. The steering wheel 504 drives the steering block 505 to rotate. The feeding robot 506 moves the arc-blocking plate 105 on the steering block 505 into the mounting groove 5011.

[0042] With this setup, the vibratory plate in the vibratory plate assembly 502 will transport the arc-breaking plate 105 to the feeder and then to the mounting bracket position at the end that matches the shape of the arc-breaking plate 105. The feeder can be a linear vibratory type or a cylinder blowing type. Then, the push plate assembly 503 will send the horizontal arc-breaking plate 105 into the steering socket 5051. Then, the steering wheel 504 driven by the motor will rotate with the steering block 505, turning the horizontal arc-breaking plate 105 to the vertical direction. In this way, the loading robot 506 can pick up the vertical arc-breaking plate 105 and insert it for installation.

[0043] The above settings are not limited. The push plate assembly 503 can be a structure in which the cylinder drives the push block to push the arc-blocking plate 105 delivered to the position by the vibratory feeder assembly 502. Alternatively, a transfer platform and a robot arm can be set up. The transfer platform is provided with a groove and a stabilizing structure that are compatible with the arc-blocking plate 105 to facilitate the push block. The robot arm moves the arc-blocking plate 105 from the end of the vibratory feeder assembly 502 to the groove on the transfer platform. This can avoid instability at the end of the vibratory feeder assembly 502. Alternatively, a horizontal robot arm can be used to directly grab the arc-blocking plate 105 and insert it into the steering socket 5051.

[0044] In a preferred embodiment, a stabilizing block 507 is provided inside the steering socket 5051, and the stabilizing block 507 is reset in the direction of the steering socket 5051.

[0045] With this configuration, the stabilizing block 507 can hold the arc-blocking plate 105 in the steering socket 5051, preventing the arc-blocking plate 105 from flying out during steering, thus making it more stable. The stabilizing block 507 can use the same structure as the clamping component 5013, or it can be equipped with a separate drive to drive its reset clamping.

[0046] In a preferred embodiment, a top plate mechanism 508 is provided between the second feeding device 5 and the unloading device 4. The top plate mechanism 508 includes a telescopic member 5081 and a top rod 5082. The telescopic member 5081 controls the top rod 5082 to move toward the connecting socket 5012.

[0047] With this setup, the insertion of the arc-blocking plate 105 is not yet stable enough, and there is a possibility that it may fall out. At this time, when it moves to the top plate mechanism 508, the telescopic component 5081 will drive the push rod 5082 to push towards the connecting piece 104, pushing the connecting piece 104 onto the arc-blocking plate 105. The protrusion of the connecting piece 104 is inserted into the hole on the arc-blocking plate 105, thus fixing the two together and making them more stable. The telescopic component 5081 can be a cylinder, hydraulic cylinder, electric push rod, or other parts.

[0048] In a preferred embodiment, the screw tightening mechanism 6 is also included, which is located above the top plate mechanism 508.

[0049] With this configuration, the screw tightening mechanism 6 can consist of a motor, a screwdriver, and a telescopic mechanism. The telescopic mechanism can be a pneumatic cylinder, a hydraulic cylinder, or an electric push rod. The terminal block 104 and the terminal block 101 can be loosely connected with a clearance fit. Then, by relying on the screw tightening mechanism 6 to tighten the terminal screw 102, the clamp 103 is pressed onto the terminal block 104 to clamp it, thereby stabilizing the various parts. The screw tightening step can be synchronized with the top plate step. When the top rod 5082 presses against the terminal block 104, the terminal screw 102 is tightened at the same time, saving time and space.

[0050] Although the present invention has been described in detail with reference to the foregoing embodiments, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
