Description

Technical Field

[0001] This invention relates to the field of pneumatic nailing technology, specifically to a multi-station synchronous pneumatic nailing device for the preparation of soft bed frames. Background Technology

[0002] The preparation of a soft bed mainly involves first nailing wooden strips together with a pneumatic nail gun to form a bed frame, then covering it with fabric, sponge, leather, etc., to form bed frame accessory modules, such as the headboard, and finally assembling them to form a complete bed. Currently, when preparing soft bed frames, companies use robotic arms and molds for automated production. First, the wooden strips are placed into the mold one by one, and then the pneumatic nail gun mounted on the robotic arm nails them together to form the bed frame.

[0003] While this technology offers a high degree of automation in the fabrication of soft bed frames through the use of robotic arms for pneumatic nailing, it still involves nailing each board individually. Since the nailing positions are identical on each bed board, we propose a multi-station synchronous pneumatic nailing device for soft bed frame fabrication to further improve production efficiency. This device can simultaneously nail multiple positions on multiple bed boards, thereby enhancing the fabrication efficiency of the bed frame. Summary of the Invention

[0004] This invention proposes a multi-station synchronous pneumatic nailing device for the preparation of soft bed frames, which solves the problem of low efficiency in nailing one nail at a time in the prior art.

[0005] The technical solution of the present invention is as follows: A multi-station synchronous pneumatic nailing device for the preparation of a soft bed frame, comprising a robotic arm, and further comprising:

[0006] Mounting bracket, which is mounted on the robotic arm;

[0007] A nailing mechanism, used for nailing, comprising:

[0008] An air supply unit, which is mounted on the mounting frame;

[0009] A nail tube, the inside of which contains a row of nails;

[0010] A cylinder, which is connected to the air supply unit, and a piston is installed inside the cylinder;

[0011] The gun head is located below the cylinder and is connected to the piston for firing the row of nails inside the nail cylinder;

[0012] An adjustable nailing bracket, mounted on the mounting frame, is used to adjust the position of the nailing mechanism. The adjustable nailing bracket includes:

[0013] A skateboard, the skateboard being mounted on the mounting bracket;

[0014] An adjustment seat, wherein multiple adjustment seats are provided, and the adjustment seats are slidably disposed on the slide plate;

[0015] The mounting plate is detachably mounted on the adjusting seat via a connecting plate. The nailing mechanism is mounted on the mounting plate. Specifically, the nail cylinder is slidably mounted on the mounting plate, and a fixing bolt is threaded onto the nail cylinder.

[0016] To ensure the stability of the cylinder, a support frame is slidably mounted on the mounting plate, and the cylinder is mounted on the support frame.

[0017] To ensure the nail is driven in completely, a hammering assembly is also included. This hammering assembly assists in driving the nail in completely, and includes:

[0018] A fixing plate, which is mounted on the support frame;

[0019] A striking block, wherein the striking block is disposed at the bottom of the support frame by means of a return spring;

[0020] A lifting component, wherein the lifting component is used to lift the impact block, the lifting component comprising:

[0021] A take-up shaft is rotatably mounted on the fixed plate, and a pull rope is wound on the take-up shaft;

[0022] A magnet is disposed at the end of the pull rope, and the magnet is in contact with the top of the impact block, the impact block being made of iron metal.

[0023] To achieve synchronous winding of multiple take-up shafts, a connector is also included, the connector comprising:

[0024] A rotating shaft is provided, and each rotating shaft corresponds to an adjusting seat. The rotating shaft is rotatably mounted on the adjusting seat, and the take-up shaft is provided with a rotating groove that is adapted to the rotating shaft.

[0025] A slider is disposed inside the rotating groove, and a groove matching the slider is formed on the rotating shaft.

[0026] To achieve precise air supply from the air supply unit to the cylinder, the air supply unit is connected to multiple adapters via an air outlet pipe. Each adapter is equipped with a valve and is connected to the cylinder via a connecting pipe.

[0027] To achieve the impact after the nail is driven in, the mounting bracket is movably mounted on the robotic arm, and the moving distance of the mounting bracket is equal to the distance between the gun head and the impact block.

[0028] To prevent multiple connecting tubes from tangling, a cable assembly is also included. The cable assembly is used to limit the movement of the connecting tubes. The cable assembly includes:

[0029] A cable tray, wherein multiple cable trays are provided, and each cable tray corresponds to a support frame, and the cable tray is mounted on the support frame;

[0030] An elastic buckle is provided on the cable tray, and the connecting tube is located inside the elastic buckle.

[0031] To improve the positioning accuracy of the nailing mechanism, the mounting plate is provided with graduations.

[0032] The working principle and beneficial effects of this invention are as follows:

[0033] 1. In this invention, the distance between multiple rows of nailing mechanisms can be adjusted by the sliding fit between the adjusting seat and the sliding plate. The distance between the nailing mechanisms in the same row can be adjusted by changing the connecting plates of different lengths and the sliding fit between the nail cylinder and the mounting plate. At the same time, the number of nailing mechanisms can be freely adjusted by the sliding fit between the nail cylinder and the mounting plate, thereby adapting to nailing different models of bed frames.

[0034] 2. In this invention, compressed gas is supplied to the cylinder by an air supply unit, which drives the piston and the gun head to move, thereby driving out the row of nails in the nail cylinder and connecting the bed board.

[0035] 3. In this invention, after nailing, the impact block is moved above the nail by the movement of the mounting frame. Initially, the magnet and the impact block are in contact. The rotation of the shaft drives multiple winding shafts to wind the pull rope, causing the magnet and the impact block to rise. After rising to a certain height, the attraction of the magnet is less than the elastic force of the spring and the tension of the pull rope. The impact block is released from the magnet and, under the action of the return spring, strikes the nail, further striking the nail. This ensures the stability of the bed frame connection and reduces the obstruction caused by the protrusion of the nail during transportation and use.

[0036] 4. Therefore, compared with the sequential nailing method of existing technologies that use a robotic arm and a single nail gun, this invention uses multiple nailing mechanisms and an adjustable nailing frame to adjust the positions of these mechanisms, adapting to nailing processes on different bed frames. It can nail multiple positions simultaneously, greatly improving work efficiency. At the same time, the moving mounting frame moves the striking block to the nail position, and the winding shaft winds up the pull rope, causing the magnet and striking block to rise. After rising to a certain height, the striking block strikes the nail under the action of the return spring, ensuring the integrity of the nailing and improving the connection quality of the bed frame.

[0053] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0054] like Figures 1 to 7 As shown, this embodiment proposes a multi-station synchronous pneumatic nailing device for soft bed frame manufacturing, including a robotic arm 1, a mounting frame 2, nailing mechanisms, and an adjustable nailing frame. Compared with the sequential nailing method of the robotic arm 1 and a single nail gun in the prior art, this invention uses multiple nailing mechanisms and adjusts the positions of the multiple nailing mechanisms through the adjustable nailing frame to adapt to the nailing processing of different bed frames. It can nail multiple positions simultaneously, greatly improving work efficiency. At the same time, the moving of the mounting frame 2 moves the striking block 302 to the nail position. The winding shaft 401 winds up the pull rope, driving the magnet 402 and the striking block 302 to rise. After rising to a certain height, the striking block 302 strikes the nail under the action of the return spring 303, ensuring the integrity of the nailing and improving the connection quality of the bed frame.

[0055] like Figures 1 to 2 As shown, the mounting frame 2 is mounted on the robotic arm 1. The robotic arm 1 can drive the mounting frame 2 to move. The nailing mechanism is mounted on the mounting frame 2, so the position of the nailing mechanism can be adjusted to match the nailing position.

[0056] like Figures 1 to 4As shown, the nailing mechanism is used for nailing. The nailing mechanism includes an air supply unit 101, a nail cylinder 102, a cylinder 103, and a nail gun head 104. The air supply unit 101 is mounted on the mounting bracket 2. The nail cylinder 102 contains a row of nails. The cylinder 103 is connected to the air supply unit 101 and has a piston inside. The nail gun head 104 is located below the cylinder 103 and is connected to the piston. It is used to launch the row of nails from the nail cylinder 102. The air supply unit 101 provides compressed air to the cylinder 103. After the compressed air enters the cylinder 103, the piston moves outward under pressure. As the piston moves, the nail gun head 104 pushes the nails out and drives them into the target object, i.e., the bed frame, connecting the bed frame. When the piston moves to a certain position... When the piston reaches its final position, the spring acts as a reset mechanism, pulling the piston back to its original position. The nailing mechanism in this invention is the same as that of current nail guns, except that the air supply equipment is centralized in the same air supply unit 101. The nailing mechanism is not the main innovation of this application and will not be described in detail here. In order to achieve precise air supply from the air supply unit 101 to the cylinder 103, the air supply unit 101 is connected to multiple adapters 5 through the air outlet pipe. The adapters 5 are equipped with valves. The adapters 5 are connected to the cylinders 103 through the connecting pipe 6. By selecting an appropriate number of cylinders 103 and connecting them to the adapters 5, different nailing needs can be met. The valves can be used to open and close the corresponding adapters 5 to prevent unused adapters 5 from escaping air, thereby ensuring air supply to the nailing mechanism in operation.

[0057] like Figures 1 to 4As shown, an adjustable nail gun frame is mounted on the mounting frame 2 and is used to adjust the position of the nailing mechanism. The adjustable nail gun frame includes a slide plate 201, an adjusting seat 202, and a mounting plate 203. The slide plate 201 is mounted on the mounting frame 2. Multiple adjusting seats 202 are provided and are slidably mounted on the slide plate 201. The X-axis position of the nailing mechanism can be adjusted by sliding the adjusting seats 202 to adapt to various nailing requirements. The adjusting seats 202 are threaded with fixing bolts. Tightening the fixing bolts allows for adjustment. The position of the joint seat 202 is locked to fix the single-row nailing mechanism and lock the position of the nailing mechanism on the X-axis. The mounting plate 203 is detachably mounted on the adjusting seat 202 via the connecting plate 204. The connecting plate 204 can be made of multiple plates of different lengths to adjust the distance between the mounting plate 203 and the adjusting seat 202 to adapt to different nailing needs. The nail cylinder 102 is slidably mounted on the mounting plate 203 and is equipped with a slider 502. The mounting plate 203 has openings... The device has a groove that matches the slider 502. A fixing bolt is threaded onto the nail cylinder 102. To improve the positional accuracy of the nailing mechanism, a scale 205 is provided on the mounting plate 203. Through the sliding cooperation between the nail cylinder 102 and the mounting plate 203, the Y-axis position of the nail cylinder 102 can be adjusted, thus allowing for more flexible adjustment of the nailing position to adapt to different nailing needs. By mounting the bed frame on the mold and moving it below the robotic arm 1, the nail ejection position of the nailing mechanism can be aligned with the nailing position. This is achieved through the air supply unit 1. 01. Air supply enables simultaneous nailing at multiple workstations, greatly improving nailing efficiency. To ensure the stability of the cylinder 103, a support frame 7 is slidably mounted on the mounting plate 203, and a slider 502 is mounted on the mounting plate 203. The support frame 7 has a groove that matches the slider 502. The cylinder 103 is mounted on the support frame 7. The sliding cooperation between the support frame 7 and the mounting plate 203 allows for the movement of the nail cylinder 102. At the same time, the support frame 7 limits the movement of the cylinder 103 and the nail cylinder 102, ensuring the stability of the nailing mechanism.

[0058] like Figures 3 to 5As shown, to ensure the nail is driven in completely, a hammering assembly is also included. The hammering assembly assists in driving the nail in completely. The hammering assembly includes a fixing plate 301, a hammering block 302, and a lifting assembly. The fixing plate 301 is mounted on the support frame 7. The hammering block 302 is mounted at the bottom of the support frame 7 via a return spring 303. The hammering block 302 is connected to a sliding rod, which slides in conjunction with the fixing plate 301. The lifting assembly is used to lift the hammering block 302. The lifting assembly includes a winding shaft 401 and a magnet 402. The winding shaft 401 is rotatably mounted on the fixing plate 301, and a pull rod is wound around the winding shaft 401. A rope and a magnet 402 are located at the end of the rope. The magnet 402 contacts the top of the striking block 302, which is made of iron. To achieve synchronous winding of multiple winding shafts 401, a connector is also included. The connector includes a rotating shaft 501 and a slider 502. Multiple rotating shafts 501 are provided, and each rotating shaft 501 corresponds to an adjusting seat 202. The rotating shaft 501 is rotatably mounted on the adjusting seat 202, which has a rotating plate on which the rotating shaft 501 is rotatably mounted. A motor 503 is mounted on the adjusting seat 202, and the rotating shaft 501 is connected to the motor 503 via a bevel gear set. The drive connection at the output end is as follows: the take-up shaft 401 has a groove adapted to the rotating shaft 501; the slider 502 is disposed inside the groove; the rotating shaft 501 has a groove matching the slider 502; the fixed plate 301 moves with the support frame 7 and the nail-driving mechanism, ensuring that the striking block 302 and the gun head 104 are always in corresponding positions; the sliding engagement of the slider 502 and the groove allows for the movement of the nail cylinder 102; the motor 503 drives the rotating shaft 501 to rotate; the sliding engagement of the slider 502 and the groove allows for the movement of the take-up shaft 401; the motor 503 drives the rotating shaft 501 and the take-up shaft 401 to rotate. Rotating the reel 401 causes the pull rope to wind up the magnet 402. Initially, the magnet 402 is in close contact with the striking block 302. As the magnet 402 rises, the striking block 302 compresses the return spring 303. After the striking block 302 rises to a certain height, the return spring 303 is compressed to a certain extent, and the magnet 402 and the striking block 302 separate. Under the elastic action of the return spring 303 and the gravity of the striking block 302, the nail can be struck, assisting in driving nails that are not fully driven into the bed frame, ensuring the connection effect of the bed frame, and reducing the inconvenience caused by protruding nails during transportation and installation.

[0059] like Figure 6As shown, to achieve the hammering effect after nailing, the mounting frame 2 is movably mounted on the robotic arm 1. The moving distance of the mounting frame 2 is equal to the distance between the gun head 104 and the hammering block 302. The robotic arm 1 is equipped with an electric cylinder 3, and the mounting frame 2 is located at the output end of the electric cylinder 3. The robotic arm 1 is equipped with a fixed frame 4. The mounting frame 2 and the fixed frame 4 are in sliding fit. After the nailing mechanism finishes nailing, the electric cylinder 3 drives the mounting frame 2 to move, moving the hammering block 302 above the nail, which is the position corresponding to the previous gun head 104. The hammering block 302 hammers the nail, driving the nail into the bed frame.

[0060] like Figures 3 to 4 As shown, to prevent multiple connecting tubes 6 from tangling, a cable guide assembly is also included. The cable guide assembly is used to limit the connecting tubes 6. The cable guide assembly includes a cable guide frame 601 and an elastic buckle 602. Multiple cable guide frames 601 are provided, and each cable guide frame 601 corresponds to a support frame 7. The cable guide frame 601 is set on the support frame 7, and the elastic buckle 602 is set on the cable guide frame 601. The connecting tube 6 is located inside the elastic buckle 602. The cable guide frame 601 can move with the support frame 7 and the nail cylinder 102 to lock the connecting tube 6 inside the elastic buckle 602, which can limit the connecting tube 6 and prevent it from tangling during the nailing process or movement, thus avoiding inconvenience to the nailing work. Multiple retaining rings can also be set on the fixing frame 4 to pass the connecting tube 6 through the retaining rings and limit the connecting tube 6.

[0061] The working principle or usage process of the multi-station synchronous pneumatic nailing device for the fabrication of the soft bed frame is as follows:

[0062] The bed board is installed on the mold, and the mold moves the bed board to the robotic arm 1. The number of nail cylinders 102 is selected according to the connection position requirements of the bed board. Then the positions of multiple nail cylinders 102 are adjusted by moving the adjusting seat 202, selecting the connecting plate 204, and moving the mounting plate 203 to adjust the position of the nail cylinders 102 so that the position of the gun head 104 corresponds to the nailing position.

[0063] The nail outlet position of the nail cylinder 102 is close to the nailing position on the bed board. The air supply unit 101 supplies air to the cylinder 103, which drives the piston and the gun head 104 to move, pushing out the nails in the nail cylinder 102 and nailing them into the bed board to connect the bed frame. After nailing is completed, the gun head 104 returns to its original position under the action of the spring, ready for the next nailing operation.

[0064] The robotic arm 1 moves the mounting frame 2 away from the bed frame by a certain height. The electric cylinder 3 moves the mounting frame 2 a certain distance so that the striking block 302 and the nail are aligned. The motor 503 drives the rotating shaft 501 and the winding shaft 401 to rotate, winding the pull rope and causing the magnet 402 and the striking block 302 to rise. After rising a certain distance, the magnet 402 and the striking block 302 disengage. Under the action of the return spring 303, the striking block 302 strikes the nail. Then, the electric cylinder 3 moves the mounting frame 2 back to its original position, and moves the subsequent bed board to the robotic arm 1 for subsequent nailing and installation work.

[0065] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
