Description

Technical Field

[0001] The invention relates to the field of switch cabinet production, and in particular to an automated production method for a switch cabinet. Background Art

[0002] The production of switch cabinets involves multiple processes, including cutting and cutting cold-rolled plates; stamping the sides and handles on the plates; using a folding machine to bend the plates to form components such as the main box body, side panels, and door; assembling and welding one side panel of the main box body; pickling and phosphating the assembled box body; electrostatic spraying of the box body; assembling the door and box body, and then packaging and shipping.

[0003] Many production processes of switch cabinets can be automated, but the welding process of the main box body and side panels is difficult to realize automated processing. The reason is that the main box body is U-shaped after bending, the open part is for installing the door, and the openings on both sides are used to assemble the side panels. The edge of the side panel has a right-angle folded edge. Figure 4 As shown, when combining the side panel and the main box body, it is necessary to open the two side openings of the main box body, insert the right-angled edges of the side panel into the inner side of the opening, and then fix them. When the main box body and the side panel are directly closed by a machine, it is easy for the right-angled edges of the side panel to hang on the outside of the side opening of the main box body and cannot be completely put together. Therefore, manual participation is required in traditional processing, and this process of automated production is difficult. Summary of the invention

[0004] The purpose of the present invention is to solve the following problems existing in the prior art: when combining the side panels and the main box body, it is necessary to open the two side openings of the main box body, insert the right-angled edges of the side panels into the inner sides of the openings, and then fix them; when the main box body and the side panels are directly closed by a machine, it is easy for the right-angled edges of the side panels to hang on the outside of the side openings of the main box body and cannot be completely assembled together. Therefore, manual participation is required in traditional processing, and this process of automated production is difficult.

[0005] In order to solve the problems existing in the prior art, the present invention provides an automated production method for a switch cabinet, comprising a driving platform, the driving platform is connected to a telescopic arm, the telescopic arm comprises an arm platform, an arm plate is linearly slidably arranged at the end of the arm platform, a positive suction component is connected to the end of the arm plate, a first single-head cylinder is installed on the surface of the arm platform, the telescopic end of the first single-head cylinder is connected to the arm plate, the positive suction component penetrates into the interior from the front opening of the main box plate to adsorb the back of the main box plate, the two sides of the arm platform are provided with side suction components, the side suction components pass through the side opening of the main box plate to adsorb the side plates, and top support components are installed at the upper and lower parts of the arm platform;

[0006] The top support assembly includes a rotating frame which rotates elastically on the surface of the arm platform through a torsion spring. A roller is rotatably connected to the end of the rotating frame away from the arm platform. A rotating handle fixedly connecting the rotating frame is arranged inside the arm platform. The rotating handle and the arm plate are connected by an elastic member. When the arm plate extends out of the arm platform, the elastic member pulls the rotating handle to swing, causing the rotating frame to expand and unfold. The roller contacts and presses the upper and lower surfaces of the main box plate, causing the front opening of the main box plate to elastically deform and open.

[0007] The production steps of the switch cabinet are as follows:

[0008] A. The main box plate is limited in front of the driving platform, and the side plates are limited on both sides of the main box plate. The telescopic arm, side suction assembly, top support assembly, and front suction assembly are driven by the driving platform to enter the inside of the main box plate through the front opening of the main box plate.

[0009] B. The first single-headed cylinder extends, causing the arm plate to extend from the end of the arm platform. The front suction assembly approaches the back of the main box plate and adsorbs and fixes the back of the main box plate.

[0010] C. When the arm plate extends, the elastic member pulls the rotating handle to rotate, and the rotating frame drives the roller to rotate and expand. The roller abuts against the upper and lower parts of the front opening of the main box plate, causing the front opening of the main box plate to elastically deform and open, and the side openings of the main box plate also expand.

[0011] D. The side suction assembly passes through the side opening of the main box plate and extends out, adsorbs and fixes the side plate. The side suction assembly contracts and drives the side plate to be placed inside the expanded side opening of the main box plate, and the side plate offsets towards the front opening of the main box plate, so that there is a gap between the side plate and the back of the main box plate.

[0012] E. The first single-headed cylinder contracts slightly, causing the edge of the side plate to closely adhere to the edge of the main box plate, accurately placing the main box plate inside the side opening of the main box plate. At the same time, the rotating frame is relaxed and rotated by a certain angle, and the roller disengages from contacting the top and bottom of the main box plate. The front opening of the main box plate resumes its shape, clamping the side opening of the main box plate outside the side plate, and accurately assembling the side plate and the main box plate.

[0013] F. The assembled side plate and main box plate are fixedly welded by a spot welder.

[0014] Preferably, the elastic member includes an elastic rope. One end of the elastic rope is fixedly connected to the rotating handle, and a telescopic column is fixed to the other end of the elastic rope. A telescopic cavity is formed at the inner end of the arm plate, and the telescopic column slides in the telescopic cavity. The telescopic column is connected to the telescopic cavity through a spring.

[0015] Preferably, the front suction assembly includes a base frame. The base frame is fixedly connected to the arm plate. A first double-headed cylinder is installed on the surface of the base frame. Two groups of rotating arms are arranged at both ends of the first double-headed cylinder, and pneumatic suction cups are installed at the ends of the rotating arms.

[0016] Preferably, the swivel arm is rotatably connected to the telescopic end of the first double-headed cylinder, the two swivel arm rotating parts located on the same side are connected with a spring, and pressure rods pointing to the swivel arms are obliquely fixed on both sides of the base frame. When the first double-headed cylinder contracts, the pressure rods squeeze the two groups of swivel arms on the same side closer together.

[0017] Preferably, the side suction assembly includes two groups of cross plates, which are symmetrically distributed on both sides of the arm platform. A second double-headed cylinder is installed on the surface of the arm platform. The two groups of cross plates are respectively fixed on the two ends of the second double-headed cylinder. The four branch ends of the cross plates are linearly slid with telescopic plates, and pneumatic suction cups are installed at the ends of the telescopic plates. Second single-headed cylinders are installed at the four branch ends of the cross plates, and the telescopic ends of the second single-headed cylinders are fixedly connected to the telescopic plates.

[0018] Preferably, the driving platform includes a support platform and a cylinder air supply assembly, a carrier block is linearly sliding on the surface of the support platform, a main cylinder is installed on the surface of the support platform, the telescopic end of the main cylinder is fixedly connected to the carrier block, a carrier column is rotatably provided on the surface of the carrier block, the arm platform is fixed at the end of the carrier column, a motor is installed on the surface of the carrier block, the shaft end of the motor is connected to the carrier column through a gear set, and the cylinder air supply assembly is connected to the main cylinder, the first single-head cylinder, the side suction assembly, and the forward suction assembly.

[0019] Compared with the related art, the switch cabinet automated production method provided by the present invention has the following beneficial effects:

[0020] 1. The present invention adopts a positive suction component to absorb and fix the main box plate, and uses a side suction component to absorb the side panels on both sides of the main box plate, so that the main box plate and the side panels can be automatically aligned and spliced. During the alignment process, the side opening of the main box plate is expanded by the top support component, so that the side panel can be accurately inserted into the side opening of the main box plate, thereby realizing automatic and accurate splicing;

[0021] 2. When the main box panel and the side panel are spliced ​​together, the present invention offsets the side panel toward the side where the side opening of the main box panel is expanded, making it easier to place the side panel in the side opening of the main box panel. When the expansion force on the main box panel is released, the side panel is simultaneously moved toward the back of the main box panel, so that the side panel is accurately inserted into the inner side of the side opening of the main box panel.

Detailed implementation manners

[0033] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0035] Embodiment 1

[0036] As Figure 1 shown, in the automatic production line of switchgear, the driving platform includes a support platform 1. A carrier block 11 is linearly slidably installed on the surface of the support platform 1 through a slider and a linear rail. A main cylinder 14 is installed at the rear end of the surface of the support platform 1. The telescopic end of the main cylinder 14 is fixedly connected to the carrier block 11. The carrier block 11 is linearly slid back and forth on the surface of the support platform 1 by the telescopic drive of the main cylinder 14. A carrier column 12 is rotatably inserted into its interior from the front end of the carrier block 11. A motor 13 is installed on the surface of the carrier block 11. The shaft end of the motor 13 is drivingly connected to the carrier column 12 through a gear set;

[0037] Install a cylinder air supply assembly 15 at the bottom of the support platform 1. The cylinder air supply assembly 15 has a gas booster device, multiple air paths and an air path control assembly, as well as a circuit controller. The cylinder air supply assembly 15 is connected to the main cylinder 14, the first single-headed cylinder 41, the side suction assembly 5, and the positive suction assembly 7;

[0038] As Figures 2-3 shown, a platform for limiting the main box plate 2 is provided at the front of the support platform 1, and platforms for limiting the side plate 3 are symmetrically provided on both sides of the main box plate 2. The main cylinder 14 extends to make the carrier block 11 slide forward. The carrier column 12 is connected to the telescopic arm 4, the side suction assembly 5, the top support assembly 6, and the positive suction assembly 7, and is sent into the main box plate 2 to perform the following closing operation;

[0039] As Figures 5-6 shown, the telescopic arm 4 includes an arm platform 42 with a hollow inner cavity. The arm platform 42 is fixedly connected to the carrier column 12. An arm plate 43 is linearly slidably installed at the front end of the arm platform 42. A first single-headed cylinder 41 is installed on the side of the arm platform 42. The telescopic end of the first single-headed cylinder 41 is fixedly connected to the arm plate 43. The arm plate 43 is driven to telescopically slide on the arm platform 42 by the telescopic movement of the first single-headed cylinder 41;

[0040] As Figures 7-8 shown, the positive suction assembly 7 includes a base frame 71. The base frame 71 is fixed to the end of the arm plate 43. A first double-headed cylinder 72 is installed on the surface of the base frame 71. Fixed shafts are provided at both ends of the first double-headed cylinder 72. Two groups of rotating arms 73 are symmetrically installed up and down in each shaft frame. Springs are connected between the rotating arms 73 on the same side, and pneumatic suction cups are installed at the ends of the rotating arms 73. Pressing rods 74 pointing to the rotating arms 73 are obliquely fixed on both sides of the base frame 71, and rollers are provided at the ends of the pressing rods 74;

[0041] When the positive suction assembly 7 enters the main box plate 2, the first double-headed cylinder 72 is in a contracted state, and the rotating arms 73 on both sides are squeezed and closed by the pressing rods 74. After the positive suction assembly 7 is in place in the main box plate 2, the first double-headed cylinder 72 extends, and the rotating arms 73 elastically expand after being released from the extrusion of the pressing rods 74. The two groups of rotating arms 73 on the same side respectively contact the upper and lower parts of the back surface of the main box plate 2. According to the size of the main box plate 2, the extension distance of the first double-headed cylinder 72 is driven so that the four pneumatic suction cups at the ends of the rotating arms 73 are aligned with the top corner positions of the back surface of the main box plate 2. Then, the first single-headed cylinder 41 is extended to make the arm plate 43 extend, and the four pneumatic suction cups at the ends of the rotating arms 73 adsorb and fix the back surface of the main box plate 2 to achieve the fixation of the main box plate 2;

[0042] As Figures 5-6 shown, the top support assembly 6 includes a rotating frame 61. The two rotating frames 61 are elastically rotated on the upper and lower surfaces of the arm platform 42 through torsion springs. A roller 62 is rotatably installed at the end of the rotating frame 61 away from the arm platform 42. A rotating handle 63 is provided inside the arm platform 42, and the rotating handle 63 is fixedly connected to the rotating frame 61;

[0043] The elastic member includes an elastic cord 46. One end of the elastic cord 46 is fixedly connected to the rotating handle 63, and the other end of the elastic cord 46 is fixed with a telescopic column 45. A telescopic cavity 44 is formed at the inner end of the arm plate 43. The telescopic column 45 is slidably inserted into the telescopic cavity 44, and the telescopic column 45 is connected to the telescopic cavity 44 through a spring;

[0044] When the top support assembly 6 is inserted into the main box plate 2, the two sets of rotating frames 61 are in a closed state. When the arm plate 43 extends to drive the positive suction assembly 7 to adsorb the main box plate 2, the rotating handle 63 is pulled by the elastic cord 46 and the telescopically installed telescopic column 45, so that the rotating frame 61 rotates and expands, and the roller 62 contacts and presses the upper and lower surfaces of the main box plate 2, causing the front opening of the main box plate 2 to elastically deform and open, and the side opening of the main box plate 2 also deforms and expands;

[0045] As Figures 9-10 shown, the side suction assembly 5 includes two sets of cross plates 52. The second double-headed cylinder 51 is fixed on the surface of the arm platform 42, and the cross plates 52 are respectively fixed at the two ends of the second double-headed cylinder 51. The four supporting ends of the cross plates 52 are linearly slid with telescopic plates 54, and pneumatic suction cups are installed at the ends of the telescopic plates 54. Second single-headed cylinders 53 are installed at the four supporting end parts of the cross plates 52, and the telescopic ends of the second single-headed cylinders 53 are fixedly connected to the telescopic plates 54;

[0046] After the top support assembly 6 expands the front opening and side opening of the main box plate 2, the second single-headed cylinder 53 is opened to extend, so that the cross plate 52 passes through the side opening of the main box plate 2 and approaches the side plate 3. According to the size of the side plate 3, the second single-headed cylinder 53 is opened to drive the telescopic plate 54 to expand and contract, adjusting the position distribution of the four pneumatic suction cups. The side plate 3 is adsorbed and fixed by the four groups of pneumatic suction cups, and then the second double-headed cylinder 51 is contracted, so that the side plate 3 is placed at the side opening position of the main box plate 2. At this time, there is a certain distance between the side plate 3 and the back surface of the main box plate 2, and the side plate 3 is located at the expanded part of the side opening of the main box plate 2;

[0047] Then, the first single-headed cylinder 41 is opened to contract a certain distance, so that the side plate 3 gradually approaches the back surface of the main box plate 2 from the inner side of the side opening of the main box plate 2 until the right-angle bent edge of the side plate 3 is tightly attached to the back surface of the main box plate 2. During this process, the elastic cord 46 gradually shortens, and the telescopic column 45 resets a certain distance, so that the rotating frame 61 rotates back a certain angle, and the roller 62 disengages from pressing the upper and lower surfaces of the main box plate 2, causing the upper and lower surfaces of the main box plate 2 to elastically recover, and the edge of the side opening of the main box plate 2 precisely fits the right-angle edge of the side plate 3, realizing the precise automatic combination of the main box plate 2 and the side plate 3;

[0048] The bonding part of the main box plate 2 and the side plate 3 is welded and fixed by a spot welder. During the welding process, the motor 13 is opened to drive the carrier column 12 to rotate, for adjusting the welding angle of the main box plate 2 and the side plate 3, realizing automatic full welding and fixing;

[0049] After welding is completed and fixed, the pneumatic suction cups of the side suction assembly 5 and the front suction assembly 7 release the adsorption of the main box plate 2 and the side plate 3, and then the telescopic arm 4, the side suction assembly 5, the front suction assembly 7, and the top support assembly 6 are contracted. When the main cylinder 14 is opened and contracted, the carrier block 11 slides backward, and the telescopic arm 4, the side suction assembly 5, the front suction assembly 7, and the top support assembly 6 are withdrawn from the front opening of the formed switch cabinet frame. After moving the switch cabinet frame, continuous combination and welding processing are carried out;

[0050] Embodiment 2

[0051] The production method of the switch cabinet based on the automated production line is as follows:

[0052] A. The main box plate 2 is limited in front of the driving platform, and the side plates 3 are limited on both sides of the main box plate 2. The telescopic arm 4, the side suction assembly 5, the top support assembly 6, and the front suction assembly 7 are driven by the driving platform to enter the inside of the main box plate 2 from the front opening;

[0053] B. The first single-head cylinder 41 extends, so that the arm plate 43 extends from the end of the arm platform 42, and the front suction assembly 7 approaches the back of the main box plate 2 and adsorbs and fixes the back of the main box plate 2;

[0054] C. When the arm plate 43 extends, the elastic member pulls the rotating handle 63 to rotate, and the rotating frame 61 drives the roller 62 to rotate and expand. The roller 62 abuts against the upper and lower parts of the front opening of the main box plate 2, causing the front opening of the main box plate 2 to elastically deform and open, and the side openings of the main box plate 2 also expand;

[0055] D. The side suction assembly 5 passes through the side opening of the main box plate 2 and extends out, adsorbs and fixes the side plate 3. The side suction assembly 5 contracts and drives the side plate 3 to be placed inside the expanded side opening of the main box plate 2, and the side plate 3 deviates towards the front opening of the main box plate 2, so that there is a gap between the side plate 3 and the back of the main box plate 2;

[0056] E. The first single-head cylinder 41 contracts slightly, so that the edge of the side plate 3 is closely attached to the edge of the main box plate 2, and the main box plate 2 is accurately placed inside the side opening of the main box plate 2. At the same time, the rotating frame 61 is released and rotated by a certain angle, and the roller 62 is disengaged from the contact with the top and bottom of the main box plate 2. The front opening of the main box plate 2 resumes its shape, so that the side opening of the main box plate 2 clamps the outside of the side plate 3, and the side plate 3 and the main box plate 2 are accurately assembled;

[0057] F. The assembled side plate 3 and main box plate 2 are fixedly welded by a spot welder.
