[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-8 The present invention provides a technical solution: an automatic assembly equipment for the production of explosion-proof tank front display, including a workbench 1, and a shell feeding assembly 2 and a bolt feeding assembly 3 are provided on the upper surface of the workbench 1.

[0021] The outer casing feeding assembly 2 includes a left box 201 and a right box 202 symmetrically fixed on the upper surface of the workbench 1. A first robotic arm 4 and a second robotic arm 5 are fixedly arranged on the upper surface of the left box 201. The ends of the first robotic arm 4 and the second robotic arm 5 are respectively provided with a gripper 401 and an electric screwdriver 501.

[0022] It is worth noting that the first robotic arm 4 and the second robotic arm 5 can flexibly adjust the spatial position of the gripper 401 and the electric screwdriver 501 to adapt to the assembly needs of different positions. The gripper 401 and the electric screwdriver 501 work together to complete the shell transfer and bolt tightening respectively, realize the automation of the assembly process, reduce the manual bolt tightening operation steps, improve assembly efficiency, and ensure the consistency of bolt tightening torque, thereby improving the product assembly quality.

[0023] The left box 201 and the right box 202 are symmetrically distributed on the upper surface of the workbench 1. The opposite surfaces of the left box 201 and the right box 202 are provided with corresponding strip-shaped limiting holes. The inner walls of the left box 201 and the right box 202 are fixed with drive motors 203. The output end of the drive motor 203 is fixed with a drive screw 204. The surface of the drive screw 204 is threaded with a moving frame 205. One end of each moving frame 205 extends to the outside of the strip-shaped limiting hole and is fixed with an electric telescopic rod 206. The telescopic ends of the two electric telescopic rods 206 are fixed with feeding clamps 207.

[0024] It is worth noting that by driving the drive screw 204 to rotate via the drive motor 203, the moving frame 205 can move horizontally along the drive screw 204, thereby driving the electric telescopic rod 206 and the feeding clamp 207 to move synchronously. The distance between the two feeding clamps 207 can be adjusted according to the different specifications of the display shell, making it highly adaptable. The telescopic action of the electric telescopic rod 206 can clamp and release the shell by the feeding clamp 207, completing the rapid positioning of the shell, replacing manual clamping and positioning, reducing manual operation errors, and improving the positioning accuracy of shell feeding.

[0025] The bolt feeding assembly 3 includes an electric push rod 301, a support frame 302, and four support columns fixedly connected to the upper surface of the right housing 202. A vibrating base plate 303 is provided on the upper surface of the support frame 302. Two bolt storage boxes 304 are symmetrically fixedly connected to the upper surface of the vibrating base plate 303. Support plates 305 are fixedly connected to the top of the four support columns. Two bolt feeding holes 306 are opened on the upper surface of the support plate 305. Two rectangular feeding shells 307 are fixedly connected to the lower surface of the support plate 305.

[0026] The upper surface of the support frame 302 has two limiting through holes. The inner wall of the limiting through holes is slidably connected to the support rods 320. The top ends of the two support rods 320 are fixedly connected to the lower surface of the vibration base plate 303. The lower surface of the vibration base plate 303 is fixedly installed with a vibration motor 321. The surface of the support rods 320 is fitted with a support spring. The top end of the support spring is fixedly connected to the lower surface of the vibration base plate 303, and the bottom end of the support spring is fixedly connected to the upper surface of the support frame 302.

[0027] It is worth noting that the vibration force generated by the vibration motor 321 when it is working can drive the vibration base plate 303 to vibrate up and down. The support spring can also buffer and protect the vibration base plate 303, reduce hard collisions during vibration, and extend the service life of the vibration components.

[0028] A bolt slide tube 318 is fixedly embedded on the side of the rectangular feeding shell 307. The bolt slide tube 318 is inclined and its bottom end extends into the interior of the rectangular feeding shell 307. A rubber connecting sleeve 319 is fixedly connected to the top end of the bolt slide tube 318. The end of the rubber connecting sleeve 319 away from the bolt slide tube 318 is fixedly connected to the output end of the bolt storage box 304. The bottom of the bolt storage box 304 is in communication with the interior of the rubber connecting sleeve 319.

[0029] It is worth noting that the internal size limitation of the bolt storage box 304 enables the single-bolt arrangement. Combined with the vibration force of the vibration base plate 303, the bolts can be pushed to slide orderly along the bolt storage box 304, the rubber connecting sleeve 319, and the bolt slide tube 318 into the rectangular feeding shell 307, avoiding the stacking and messy situation of bolts, and realizing the automatic sorting and feeding of bolts. The flexible structure of the rubber connecting sleeve 319 can buffer the connection stress between the bolt slide tube 318 and the bolt storage box 304 during vibration, prevent the connection part from breaking due to long-term vibration, and improve the stability of the structural connection.

[0030] The rectangular feeding shell 307 is positioned corresponding to the bolt feeding hole 306, and the two rectangular feeding shells 307 are respectively located directly below the two bolt feeding holes 306. The electric push rod 301 is located directly below the rectangular feeding shell 307, and the telescopic end of the electric push rod 301 is fixedly connected to a T-shaped push plate 308. Two feeding push blocks 309 are fixedly connected to the upper surface of the T-shaped push plate 308. The position of the feeding push block 309 corresponds to the rectangular feeding shell 307, and the size of the feeding push block 309 matches the rectangular feeding shell 307. The feeding push block 309 is slidably connected to the inner wall of the rectangular feeding shell 307.

[0031] It is worth noting that the electric push rod 301 drives the T-shaped push plate 308 and the feeding push block 309 to move vertically upward, which can accurately push the bolts inside the rectangular feeding shell 307 out along the bolt feeding hole 306, thus achieving precise bolt pushing; the guide post 316 plays a guiding and limiting role on the sliding of the T-shaped push plate 308, preventing the T-shaped push plate 308 from deviating during the movement, and ensuring the precise cooperation between the feeding push block 309 and the rectangular feeding shell 307.

[0032] A guide post 316 is fixedly connected between the lower surface of the support plate 305 and the upper surface of the right box 202. A sliding through hole matching the guide post 316 is opened on the upper surface of the T-shaped push plate 308. The T-shaped push plate 308 is slidably connected to the surface of the guide post 316 through the sliding through hole. A compression spring 317 is sleeved on the surface of the guide post 316. The bottom end of the compression spring 317 is fixedly connected to the upper surface of the T-shaped push plate 308, and the top end of the compression spring 317 is fixedly connected to the lower surface of the support plate 305.

[0033] A liquid storage box 310 is fixedly connected to the upper surface of the support plate 305. The liquid storage box 310 is filled with bolt anti-jamming spray. A pressurizing cylinder 311 is fixedly connected to the lower surface of the support plate 305. A piston rod 312 is slidably arranged on the inner wall of the pressurizing cylinder 311. The bottom end of the piston rod 312 extends to the outside of the pressurizing cylinder 311 and is fixedly connected to the upper surface of the T-shaped push plate 308. An air inlet pipe 313 is fixedly connected to the air inlet end of the pressurizing cylinder 311. A one-way air inlet valve is fixedly connected to the air inlet end of the air inlet pipe 313. The exhaust end of the pressurizing cylinder 311 extends to the inside of the liquid storage box 310 and is fixedly equipped with a one-way exhaust valve.

[0034] A liquid guide bend 314 is fixedly embedded on the lower surface of the liquid storage box 310. The end of the liquid guide bend 314 away from the liquid storage box 310 extends into the interior of the rectangular feed shell 307. A liquid outlet hole is opened on the inner wall of the rectangular feed shell 307. An atomizing nozzle 315 is fixedly connected to the inner wall of the liquid outlet hole. The output end of the liquid guide bend 314 is fixedly connected to the input end of the atomizing nozzle 315. A check valve is fixedly connected to the output end of the liquid guide bend 314.

[0035] It is worth noting that when the T-shaped push plate 308 moves under the drive of the electric push rod 301, it can simultaneously drive the piston rod 312 to slide along the inner wall of the pressurizing air cylinder 311, realizing the automatic air intake and pressurization exhaust of the pressurizing air cylinder 311. Pressurization is achieved by utilizing the movement of the equipment itself, reducing the energy consumption and manufacturing cost of the equipment. The compressed air discharged from the pressurizing air cylinder 311 into the liquid storage box 310 can create pressure on the bolt anti-jamming spray in the box, pushing the spray along the liquid guide bend 314 and spraying it out in a mist from the atomizing nozzle 315. This evenly adheres to the bolt surface inside the rectangular feeding shell 307, reducing the friction between the bolt and the rectangular feeding shell 307 and the feeding push block 309, fundamentally avoiding the problem of bolt jamming and blockage during the feeding process, and ensuring the continuity of bolt feeding. The atomizing nozzle 315 sprays the spray in a mist, improving the uniformity of spraying.

[0036] Working principle: First, place the explosion-proof tank front display shell to be assembled on the workbench 1 between the left box 201 and the right box 202. Start the drive motor 203 in the shell feeding assembly 2. The drive motor 203 drives the drive screw 204 to rotate, so that the moving frame 205 moves horizontally along the drive screw 204. Then start the electric telescopic rod 206. The telescopic end of the electric telescopic rod 206 extends and drives the feeding clamp 207 to clamp the display shell. Simultaneously, the assembly bolts are placed in batches into the two bolt storage boxes 304 of the bolt feeding assembly 3. Due to their size limitations, the bolts are arranged vertically as individual bolts within the bolt storage boxes 304. The vibration motor 321 is activated, generating vibration that causes the vibration base plate 303 to vibrate up and down. Under this vibration, the bolts inside the bolt storage boxes 304 slide sequentially along the rubber connecting sleeve 319 and the inclined bolt slide tube 318, eventually entering the rectangular feeding shell 307 one by one. Then, the electric push rod 301 is activated, its telescopic end extending vertically upwards, causing the T-shaped push plate 308 to slide upwards along the guide post 316. The T-shaped push plate 308 moves... During the process, on the one hand, the feeding pusher 309 slides upward along the inner wall of the rectangular feeding shell 307, precisely pushing the bolts inside the rectangular feeding shell 307 out along the bolt feeding hole 306 and pushing them to the bolt assembly hole of the display shell; on the other hand, the T-shaped pusher 308 simultaneously drives the piston rod 312 to slide along the inner wall of the pressurizing air cylinder 311, forcing the air inside the pressurizing air cylinder 311 into the liquid storage box 310 through the one-way exhaust valve. The pressure inside the liquid storage box 310 increases, pushing the bolt anti-jamming spray inside the box to flow along the liquid guide bend 314 and spray out in a mist from the atomizing nozzle 315, evenly spraying it on the bolt surface inside the rectangular feeding shell 307 to lubricate the bolts and prevent jamming during the bolt pushing process.

[0037] As the bolt is pushed to the mounting hole of the outer casing, the first robotic arm 4 and the second robotic arm 5 are activated. The first robotic arm 4 uses the gripper 401 to assist in limiting the position of the display casing to prevent the casing from shifting during assembly. The second robotic arm 5 adjusts the spatial position of the electric screwdriver 501 so that the tip of the electric screwdriver 501 is precisely aligned with the nut of the bolt. Then, the electric screwdriver 501 is activated and rotates forward to tighten the bolt in the mounting hole of the display casing, completing the assembly of a single bolt.
