Description

Technical Field

[0001] This application relates to the technical field of mounting the cover of a junction box, and in particular to a device for mounting the cover of a junction box. Background Technology

[0002] In the electrical field, junction boxes, as core components for connecting, branching, and storing electrical circuits and components, are widely used inside various electrical devices such as distribution boxes, electrical control cabinets, and lighting equipment. Their installation accuracy and stability directly affect the insulation performance, signal transmission efficiency, and overall operational safety of the electrical system.

[0003] Typically, a junction box consists of a box body and a cover. The box body has an opening, is deformable, and includes a slot. The cover includes a buckle. During installation, the cover needs to be inserted into the opening and the buckle needs to be inserted into the slot to complete the assembly.

[0004] Existing box lid snap-fit ​​methods mostly utilize power components such as cylinders. After aligning the box lid with the opening, the cylinder is used to move the box lid so that it is vertically snapped into the opening, completing the snap-fit ​​between the slot and the buckle.

[0005] When there are many clips and multiple clips are distributed along the outer periphery of the box, the box body is compressed and deformed when the cylinder drives the lid to be vertically inserted into the opening. The box body is subjected to a large external force, and at this time, the box body will generate an internal force to resist the deformation. When the external force exceeds the internal force, the box structure may undergo irreversible plastic deformation or even damage. In addition, when there is a processing error between individual clips and their corresponding slots, since multiple clips engage at the same time when the lid is vertically engaged, the clip with the processing error will have difficulty engaging into the slot, thus causing deformation or even damage to the box structure. Summary of the Invention

[0006] To minimize the risk of damage to the box structure by the box cover during assembly, this application provides a box cover installation device for a wiring box.

[0007] The cover installation device for a junction box provided in this application adopts the following technical solution: A box cover installation device for a wiring box includes a feeding device and an assembly device, wherein the feeding device is used to feed out the box cover and the assembly device is used to assemble the box cover onto the box body. The assembly device includes a power mechanism and a pressing mechanism connected to the power mechanism; The pressing mechanism includes a mounting base connected to a rotating component. A pressing block is rotatably connected to the mounting base. The pressing block has an adsorption port and a flow channel communicating with the adsorption port. The pressing block has a pressing end. A driving component is provided on the mounting base and rotatably connected to the pressing end. The driving component can apply force to the pressing end to make the pressing block rotate.

[0008] By adopting the above technical solution, after the lid is fed out by the feeding device, the driving power mechanism moves the pressing pry block to contact the lid. At this time, it is necessary to ensure that the suction port is covered by the lid. Then, the suction port is used to suck the lid in by the flow channel. After the lid is sucked up, the driving component drives the pressing end to rotate, which in turn causes the pressing pry block to rotate. The lid will then be in an inclined state. The driving power mechanism drives the lower end of the inclined lid to insert into the box body. Then, the driving component drives the pressing pry block to rotate, which, together with the driving power mechanism, moves the lid to press it into the box body. When pressing the lid using the above pressing method, since the lid enters the box body from one end and then gradually snaps into the box body, the engagement timing of the multiple buckles on the lid is not consistent. The multiple buckles are engaged step by step. Furthermore, this installation method results in a smaller external force on the box body at the same time, making it less likely for the box body to undergo large deformations that could damage its structure.

[0009] Preferably, the power mechanism includes a three-axis power assembly and a belt drive connected to the three-axis power assembly, and the mounting base is connected to the belt drive.

[0010] By adopting the above technical solution, and by using a three-axis power assembly to drive the three-axis movement of the pressing mechanism, the lid can be pressed into the box body more reliably. Furthermore, by using a rotating component, it can accommodate more types of lid installations, such as round lids.

[0011] Preferably, the pressing block is equipped with a sensor for detecting the pressure of the box.

[0012] By adopting the above technical solution, the pressure data of the box body can be detected by the sensor to determine the pressure at each position of the box body, i.e. the external force it is subjected to. Based on the pressure data, permanent plastic deformation can be prevented when the box body and the lid are connected.

[0013] Preferably, the feeding device includes a support platform, a feeding mechanism for feeding the box cover onto the support platform, a flipping mechanism for flipping the box cover on the support platform, and a feeding mechanism for feeding the box cover on the support platform to one side of the assembly device.

[0014] By adopting the above technical solution, the feeding mechanism can deliver the box cover to the carrier platform, the flipping mechanism can flip the box cover on the carrier platform, and the feeding device can deliver the flipped and adjusted box cover to the side of the assembly device for assembly.

[0015] Preferably, the feeding mechanism includes a flexible vibratory feeder, a frame is provided on one side of the flexible vibratory feeder, a three-axis moving assembly is provided on the frame, and a clamping component and a CCD camera are installed on the three-axis moving assembly.

[0016] By adopting the above technical solution, the flexible vibratory feeder can vibrate the lid to make it flip over, and the driving three-axis moving component can move the clamping component to move the lid on the flexible vibratory feeder to the carrier platform.

[0017] Preferably, the flipping mechanism includes a transverse reciprocating drive member disposed on one side of the support platform, the transverse reciprocating drive member being connected to a vertical reciprocating drive member, the vertical reciprocating drive member being connected to a rotary drive member, and the rotary drive member being connected to a clamping member.

[0018] By adopting the above technical solution, since some larger and heavier box lids cannot be flipped by the vibration of the flexible vibrating plate, it is necessary to drive the horizontal reciprocating drive, the vertical reciprocating drive and the clamping part to flip them so that the box lids can be flipped.

[0019] Preferably, the feeding mechanism includes a first belt conveyor, a discharge assembly, and a plurality of parallel second belt conveyors. Both the first belt conveyor and the second belt conveyors are used to convey box lids, and the discharge assembly is used to arrange the box lids conveyed by the first belt conveyor onto the plurality of second belt conveyors.

[0020] By adopting the above technical solution, multiple box lids can be prepared simultaneously for installation.

[0021] Preferably, the discharge assembly includes a robotic arm connected to a suction cup.

[0022] By adopting the above technical solution, the driving robot and suction cup can arrange multiple box covers on the second belt conveyor for installation.

[0023] Preferably, the pressing mechanism is provided for each of the second belt conveyors.

[0024] By adopting the above technical solution, this application can complete the simultaneous installation of multiple box covers.

[0025] In summary, the present invention has at least one of the following beneficial technical effects: 1. After the lid is fed out by the feeding device, the drive mechanism moves the pressing pry bar to contact the lid. At this point, it is necessary to ensure that the suction port is covered by the lid. Then, suction is applied through the flow channel to make the suction port hold the lid. After the lid is lifted, the drive component rotates the pressing end, causing the pressing pry bar to rotate. The lid will then be tilted. The drive mechanism drives the lower end of the tilted lid to insert into the box body. The drive component then rotates the pressing pry bar, cooperating with the drive mechanism to move the lid and press it into the box body. When pressing the lid using the above method, because the lid enters the box body from one end and then gradually snaps into place, the engagement timing of the multiple clips on the lid is not consistent. The multiple clips engage gradually. Furthermore, this installation method results in less external force on the box body at any given time, making it less likely for the box body to undergo significant deformation that could damage its structure. 2. The flexible vibratory feeder vibrates the lid to flip it over, and the driving three-axis moving assembly moves the clamping component to move the lid from the flexible vibratory feeder to the support platform. Additionally, since some larger and heavier lids cannot be flipped by the vibration of the flexible vibratory feeder, it is necessary to drive a horizontal reciprocating drive, a vertical reciprocating drive, and a clamping component to flip them over.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0030] This application discloses a cover mounting device for a junction box. It is used to minimize damage to the box structure during assembly by the cover.

[0031] Reference Figure 1 A box cover installation device for a wiring box includes a workbench 1, on which a feeding device 2 and an assembly device 3 are installed. The feeding device 2 is used to deliver the box cover, and the assembly device 3 is used to assemble the box cover onto the box body. Specifically, the box cover has a front and a flip side, and the assembly device 3 needs to press the box cover with the front side facing up into the box body.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The feeding device 2 includes a support platform 21 on the workbench 1, a feeding mechanism 22 for feeding the box cover onto the support platform 21, a flipping mechanism 23 for flipping the box cover on the support platform 21, and a feeding mechanism 24 for feeding the box cover on the support platform 21 to one side of the assembly device 3.

[0033] Reference Figure 1 and Figure 2The feeding mechanism 22 includes a flexible vibratory plate 221 mounted on the workbench 1. The flexible vibratory plate 221 can carry the lid and vibrate to flip smaller and lighter lids so that the lid faces upwards for subsequent installation. A frame 222 connected to the workbench 1 is provided on one side of the flexible vibratory plate 221. A three-axis moving assembly 223 is provided on the frame 222. The three-axis moving assembly 223 is a three-axis cylinder. The three-axis moving assembly 223 is equipped with a clamping component 224 and a CCD camera. The clamping component 224 is a gripper cylinder. The CCD camera can determine the orientation of the lid and its position on the flexible vibratory plate 221.

[0034] Reference Figure 3 Since some of the lids are heavy and large, it is difficult to flip them by vibration. Therefore, in order to facilitate the flipping of heavy and large lids, the flipping mechanism 23 includes a transverse reciprocating drive 231 located on one side of the support platform 21 and installed on the worktable 1. The transverse reciprocating drive 231 is connected to a vertical reciprocating drive 232. The vertical reciprocating drive 232 is connected to a rotary drive 233. The rotary drive 233 is connected to a clamping component 234. The transverse reciprocating drive 231, the vertical reciprocating drive 232 and the rotary drive 233 are all cylinders. The clamping component 234 is a gripper cylinder.

[0035] After the three-axis moving assembly 223 and the clamping component 224 grasp the box cover and place it on the carrier platform 21, based on the detection and judgment of the CCD camera, if the box cover is facing up, the flipping mechanism 23 does not work; if the box cover is facing down, the horizontal reciprocating drive component 231 and the vertical reciprocating drive component 232 work to drive the clamping component 234 to clamp the box cover and move it away from the carrier platform 21. The rotation drive component 233 works to drive the clamping component 234 to rotate, thereby causing the box cover to flip 180°. Then, in conjunction with driving the horizontal reciprocating drive component 231 and the vertical reciprocating drive component 232, the box cover is put back in its original position.

[0036] Reference Figure 3 and Figure 4 The feeding mechanism 24 includes a clamping assembly 241, a first belt conveyor 242, a discharging assembly 243, and a plurality of parallel second belt conveyors 244. The clamping assembly 241 is connected to the transverse reciprocating drive 231. The discharging assembly 243 and the plurality of second belt conveyors 244 are all mounted on the worktable 1. The clamping assembly is used to feed the box cover on the support platform 21 to the first belt conveyor 242. The first belt conveyor 242 and the second belt conveyor 244 are both used to transport the box cover. The discharging assembly 243 is used to arrange the box cover conveyed by the first belt conveyor 242 onto the plurality of second belt conveyors 244.

[0037] Reference Figure 3 and Figure 4The clamping assembly 241 includes a vertical driving cylinder 2411 connected to the horizontal reciprocating drive member 231 and a clamping drive cylinder 2412 connected to the vertical driving cylinder 2411. The conveying inlet of the first belt conveyor 242 is located on one side of the clamping drive cylinder 2412. The discharging assembly 243 includes a robot arm 2431, which is connected to a suction cup 2432. Driving the robot arm 2431 and the suction cup 2432 can sequentially place the box caps on the first belt conveyor 242 onto multiple second belt conveyors 244. In this embodiment, there are three second belt conveyors 244, so at least three box caps can be prepared at once.

[0038] Reference Figure 5 The assembly device 3 includes a power mechanism 31 and a pressing mechanism 32 connected to the power mechanism 31. The power mechanism 31 includes a three-axis power assembly 311 and a belt rotating component 312 connected to the three-axis power assembly 311. The three-axis power assembly 311 is a three-axis cylinder, the belt rotating component 312 is a geared motor, and the pressing mechanism 32 is connected to the belt rotating component 312.

[0039] Reference Figure 6 The pressing mechanism 32 includes a mounting base 321 connected to the rotating component 312. A pressing pry block 322 is rotatably connected to the mounting base 321. The lower end of the pressing pry block 322 has an adsorption port and a flow channel communicating with the adsorption port. A connector 323 communicating with the flow channel is also installed on the pressing pry block 322. The right end of the pressing pry block 322 is a pressing end 324. A driving component 325 is rotatably connected to the pressing end 324 on the mounting base 321. The driving component 325 is a cylinder capable of outputting an arc trajectory, such as a swing cylinder. The driving component 325 can apply force to the pressing end 324 to make the pressing pry block 322 rotate.

[0040] The three-axis power assembly 311 drives the pressing pry block 322 to move and contact the lid. At this time, it is necessary to ensure that the suction port is covered by the lid. Then, the suction port is made to suck the lid by the flow channel. After the lid is sucked up, the drive component 325 drives the pressing end 324 to rotate so that the pressing pry block 322 rotates. The lid will be tilted at this time. The drive power mechanism 31 drives the lower end of the tilted lid to insert into the box. Then, the drive component 325 drives the pressing pry block 322 to rotate back to its original position and cooperates with the drive three-axis power assembly 311 to move the lid to press the lid into the box.

[0041] This application can reliably install on different types of lids, such as: Reference Figure 7For rectangular box lids that require high precision in positioning after being pressed into the box, this application can be used to implement a lid pressing action of first tilting and then pressing vertically. The tilting and pressing action ensures that the lid is reliably inserted into the box, and the subsequent vertical pressing action ensures that the lid is in the correct position.

[0042] Reference Figure 8 For a round box lid with a wire hole, the box body usually has a wire groove for the wire to pass through. Since the relative position of the wire hole and the wire groove needs to be ensured, for example, the wire hole needs to be aligned with the wire groove in the circumferential direction, in this application, before pressing the box lid, the box lid can be rotated by driving the rotating component 312 to adjust the position of the wire hole relative to the wire groove.

[0043] Reference Figure 9 For some box lids that require a specific tilt angle to be inserted into the box, such as the lid of a storage box with a hook, the push-to-open block 322 can be rotated by driving the drive component 325 so that the push-to-open block 322 can present different tilt angles for subsequent installation.

[0044] Reference Figure 6 The pressing pry block 322 is equipped with a sensor 33 for detecting the pressure of the box body. The sensor 33 is such as a pressure sensor or an ultrasonic sensor. Based on the pressure data of the box body detected by the sensor 33, the pressure at each position of the box body can be determined, i.e. the external force situation. Based on the pressure data, an early warning can be given to prevent permanent plastic deformation when the box body is connected to the lid.

[0045] The implementation principle of the junction box cover installation device in this application embodiment is as follows: The flexible vibrating plate 221 supports multiple box lids and drives the box lids to vibrate. The three-axis moving component 223 and the clamping component 224 are driven to grab the box lids and place them on the support platform 21. Based on the detection and judgment of the CCD camera, if the box lid is facing up, the flipping mechanism 23 does not work. If the box lid is facing down, the horizontal reciprocating drive component 231 and the vertical reciprocating drive component 232 work to drive the clamping component 234 to clamp the box lid and move it away from the support platform 21. The rotation drive component 233 works to drive the clamping component 234 to rotate, thereby causing the box lid to flip 180°. Then, in conjunction with the drive of the horizontal reciprocating drive component 231 and the vertical reciprocating drive component 232, the box lid is put back in its original position. The box cover is clamped and placed on the first belt conveyor 242 by using the horizontal reciprocating drive 231, the vertical drive cylinder 2411 and the clamping drive cylinder 2412. The box cover is then placed one by one on the first belt conveyor 242 onto multiple second belt conveyors 244 by using the robot arm 2431 and the suction cup 2432, thus completing the preparation of the box cover. With external assistance, the box is placed on one side of the assembly device 3 while keeping the box stationary. The three-axis power assembly 311 drives the pressing pry block 322 to move and contact the box cover. At this time, it is necessary to ensure that the suction port is covered by the box cover. Then, the suction port is made to suck the box cover by the flow channel. After the box cover is sucked up, the drive component 325 drives the pressing end 324 to rotate so that the pressing pry block 322 rotates. The box cover will be tilted at this time. The drive power mechanism 31 drives the lower end of the tilted box cover to insert into the box body. Then, the drive component 325 drives the pressing pry block 322 to rotate back to its original position and cooperates with the drive three-axis power assembly 311 to move the box cover to press the box cover into the box body.
