Description

Technical Field

[0001] This utility model relates to the field of automated production technology, specifically to an assembly equipment for an electrical control box cover. Background Technology

[0002] The electrical control box houses electrical control components, while the external box primarily protects the internal control board, electronic components, and wiring. During installation, the internal structure must first be installed within the box's cavity, followed by the sealing installation of the upper cover onto the lower box. Currently, the upper cover and lower box are simply secured with screws; installation merely requires placing the upper cover on the lower box's upper plate and removing the screws. However, during later maintenance, the upper cover needs to be opened. To prevent complete detachment and fall-off, technicians have implemented a hinged connection on one side before screwing it in. This hinge is integrated into the upper cover's surface. Existing technology often involves manually hinged the upper cover to the lower box before screwing it onto the equipment. This manual hinge is inefficient and prone to incomplete hinge placement, affecting the accuracy of subsequent screwing.

[0014] The working principle is as follows:

[0015] The lower box is conveyed via a conveyor line. During the conveying process, the conveying direction is first adjusted by a side-push cylinder. The conveying is paused by a material-stopping device and scanned by a barcode scanner. After scanning, the lower box continues to be conveyed. Upon reaching the lifting and positioning device, the lower box is positioned by the combined action of the material-stopping device, the third translation cylinder, and the positioning upper pressure plate. Then, a rotating material-shifting structure moves the gate plate to the other side. After a photoelectric sensor detects that the gate plate has been moved, the lower box continues to be conveyed, and again, the lower box is moved by the combined action of the material-stopping device, the third translation cylinder, and the positioning upper pressure plate. Box positioning, the top cover picking / installation component, under the action of the moving module, clamps the top cover and places it above the upper box body. After being pressed and deformed, the two ears of the top cover are slid to the two sides of the lower box body (or, after the inner support claw cylinder deforms the side ears, they are slid directly to the two sides of the lower box body). The top cover lifting cylinder drives the top cover lifting nozzle to suck up the top cover and tilt it upward to pull the top cover so that the two ears slide into the side ear sockets, completing the hinge connection between the top cover and the lower box body. The upper box body and the top cover are conveyed backward together. After positioning, the side push cylinder pushes the gate plate back to its original position, nails are driven in, and the material is unloaded.

[0028] The upper cover feeding assembly includes a baffle plate 100, a first motor-screw structure 101, and a first lifting plate 102. The baffle plate 100 is fixed to the frame, and the screw nut of the first motor-screw structure 101 is fixed to the first lifting plate 102. The first lifting plate 102 and the baffle plate 100 are connected by a sliding rail slider. The motor output end of the first motor-screw structure 101 is provided with a main sprocket, and the end of the screw is provided with a driven sprocket. The main sprocket and the driven sprocket are connected by a chain drive. The screw is mounted on the surface of the baffle plate 100 through a rolling bearing. The upper cover material tray is placed on the upper surface of the first lifting plate 102 and lifted to the material picking height under the action of the first motor-screw structure 101. The upper cover feeding assembly and the upper cover unloading assembly have the same structure.

[0029] The lower box loading conveyor line includes a conveyor line 200, a lifting and positioning device 201, and a blocking device 202. The lifting and positioning device 201 and the blocking device 202 are located below the conveying direction of the conveyor line 200. The lifting and positioning device 201 includes a first lifting cylinder and a second lifting plate. The piston shaft of the first lifting cylinder is fixedly connected to the second lifting plate.

The moving module drives the upper cover material picking / installation component to move along the X, Y, and Z axes; the moving module can be other structures in the prior art, such as cylinder, motor-sprocket chain, motor-gear rack and pinion, etc.

[0031] like Figure 5 As shown, the upper cover picking / installation assembly includes a first gripper cylinder 401 and an inner support plate 402. The gripper cylinder 401 is fixedly connected to the output end of the fourth motor-screw structure 304 via a connecting plate. The inner support plate 402 has inclined support surfaces machined on both sides. Under the action of the moving module, the gripper cylinder 401 moves to the upper cover loading assembly position to pick up the upper cover and presses down on the upper cover located above the inner support plate 402. This causes the two side ears of the upper cover to slide past the inclined support surfaces on both sides of the inner support plate 402, slightly deforming and expanding outwards. The expanded side ears of the upper cover are easily pressed down into the side ear sockets of the lower box. The inner support plate 402 is fixed to the hinged side, for example, the inner support plate 402 is fixedly connected to the positioning upper pressure plate 206 at that location.

The electrical control box with the top cover installed is then moved to the next workstation by the feeding assembly.

[0034] Specific Implementation Case 2:

[0035] An electrical control box cover assembly device includes: a cover feeding assembly, a lower box body feeding conveyor line, a moving module, a cover picking / installation assembly, a nailing assembly, and a cover unloading assembly. The cover feeding assembly is used for feeding multiple covers. The lower box body feeding conveyor line is used for linear conveying of the lower box body, transporting the product to different workstations. The moving module drives the cover picking / installation assembly to transfer the cover to the upper box body / complete the edge hinged installation of the cover and the lower box body. The nailing assembly is used to fix the cover and the lower box body with screws. The cover unloading assembly is used for unloading the cover tray.

[0036] like Figure 6 As shown, the upper cover material handling / installation assembly includes an external gripper cylinder 407 and an internal support gripper cylinder 408. The cylinder bodies of both the external gripper cylinder 407 and the internal support gripper cylinder 408 are fixed to a connecting plate, which is connected to the output end of the fourth motor-screw structure 304. The external gripper cylinder 407 clamps the upper cover from the outside, and the internal support gripper cylinder 408 pushes the side ears of the upper cover from the inside out to deform them, facilitating the insertion of the side ears of the upper cover from the top of the upper box into the sides of the lower box. All other structures are the same as the previous ones.

[0037] Specific Implementation Case 3:

[0038] Based on specific implementation cases 1 and 2, the electrical control box cover assembly equipment can also select one or more of the following preferred technical solutions;

[0039] Optionally, the upper cover feeding assembly further includes a straightening structure, which includes a first translation cylinder 103 and a second straightening cylinder 104. Both the first translation cylinder 103 and the second translation cylinder 104 are fixed to the surface of the baffle plate 100. The piston shafts of the first translation cylinder 103 and the second translation cylinder 104 are respectively fixedly connected to the corner plate and the push plate. The first translation cylinder 103 and the second straightening cylinder 104 drive the corner plate and the push plate to translate, thus straightening the tilted upper cover material tray.

[0040] Optionally, the lower box loading conveyor line also includes a side-push cylinder 203, a rotary feeding structure 204, a third translation cylinder 205, a positioning upper pressure plate 206, and a lever cylinder 207. The side-push cylinder 203 is installed on one side of the inlet end of the conveyor line 200. The side-push cylinder 203 pushes the lower box conveyed on the conveyor line 200 to be upright, avoiding tilted conveying. The rotary feeding structure 204 includes a rotary cylinder 2041 and a feeding lever 2042. The feeding lever 2042 is fixed to the rotary output end of the rotary cylinder 2041. The gate plate in the lower box is moved to the other side by the material-pulling rod 2042 to facilitate the placement of the upper cover; otherwise, it will interfere with the upper cover. A photoelectric sensor at this location detects whether the gate plate has been moved into place. The piston shaft of the third translation cylinder 205 is fixedly connected to the cylinder body of the material-blocking device 202. The material-blocking device 202 functions solely to block material at the inlet position to facilitate barcode scanning. However, in the middle section of the conveyor, when the lower box needs to be positioned using the lifting and positioning device 201, the material-blocking device 202 must not only block material but also, if necessary, adjust its position. Therefore, it works in conjunction with the third translation cylinder... The output end of cylinder 205 is connected to facilitate the translation and alignment of the lower box body; the positioning upper pressure plate 206 is fixed on the support plate on both sides of the conveyor line 200, and is located directly below the positioning upper pressure plate 206 when the lower box body needs to be lifted and positioned, so as to prevent the lower box body from tipping over during the lifting and positioning process; the lever cylinder 207 is fixed on the upper plate of the support plate on one side of the conveyor line 200, for example, the same connecting plate is installed on the upper plate of the positioning upper pressure plate 206, and the output end of the lever cylinder 207 is equipped with a lever, which is used to push back the gate plate after the upper cover is hinged and installed, so as to facilitate subsequent operations.

[0041] Optionally, the upper cover material handling / installation assembly further includes a lifting cylinder 403, a lifting nozzle 404, and a lifting cylinder mounting plate. The output end of the lifting cylinder 403 is fixedly connected to the lifting nozzle 404. The lifting cylinder 403 is fixedly installed above the lower box body feeding conveyor line via the lifting cylinder mounting plate. Optionally, the lifting cylinder mounting plate includes a mounting plate, a lifting plate, and a rotating plate. The mounting plate is fixed to the two side support plates of the conveyor line 200. The lifting plate surface is machined with lifting... The lifting plate has a waist-shaped hole, and the lifting plate is fixedly connected to the mounting plate by screws. The rotating plate has an arc-shaped hole, and the rotating plate is fixed to the lifting plate by a rotating shaft. After the rotating plate rotates to the target angle, the angle between the rotating plate and the lifting plate is fixed by screws. The lifting cover cylinder 403 is fixedly connected to the rotating plate. After the side ears of the upper cover contact the two sides of the lower box, it is very likely that the side ears and the side ear sockets are not truly matched and installed. By rotating the upper cover with the IGN by a certain angle, the upper cover and the lower box can be hinged on one side.

[0042] Optionally, the upper cover material handling / installation assembly further includes a lifting cylinder 405 and a vacuum nozzle 406. The lifting cylinder 405 is fixedly connected to the output end of the fourth motor-screw structure 304 via a connecting plate, and the vacuum nozzle 406 is fixedly connected to the output end of the lifting cylinder 405 via a nozzle fixing bracket. When the upper cover material tray in the upper cover loading assembly is empty, the moving module drives the vacuum nozzle 406 to transfer the empty upper cover material tray to the upper cover unloading assembly, completing the unloading of the empty upper cover material tray.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
