Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of welding of fire extinguisher bottles, and specifically relates to an automatic processing equipment for fire extinguisher bottles. BACKGROUND

[0002] As a main component of fire-fighting equipment, a fire extinguisher bottle requires excellent pressure resistance, and the pressure resistance parameter of the gas storage bottle is designed to be at least 10 MPa or above. To achieve such pressure resistance, any defects cannot occur during welding.

[0003] In the current production process of fire extinguisher bottles, a steel plate with a thickness of about 1.2-2 mm is curled into a cylindrical shape, and laser welding is performed along the butt joint line, and the welding seam is required to be smooth and flat, without virtual welding, welding bumps or cracks and the like. Subsequently, the coupling groove is rolled and coupled to the bottle bottom and the bottle opening for coupling and welding. In the current automatic processing equipment, after the rolling and splicing, the splicing is directly welded by the top support at both ends of the work station, and after the welding is completed, the manual quality inspection process is performed to determine whether the welding seam meets the requirements. There is a lack of detection and correction during the splicing process, and the NG products caused by splicing deviation, such as missing welding, burning and cracks in the welding seam, are screened out in the manual quality inspection process, so that the whole bottle body is scrapped. This undoubtedly increases the production cost and reduces the fault tolerance.

[0004] The application provides an automatic processing equipment for fire extinguisher bottles to judge the coupling posture in advance, correct before welding or send out, and reduce the error cost. SUMMARY

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0039] As Figures 1 to 7 shown, the present application provides a fire extinguisher bottle automatic processing equipment, which comprises a rolling mechanism 100 for rolling coupling grooves at both ends of the fire extinguisher bottle;

[0040] A welding station is used for receiving the fire extinguisher bottle with completed rolling grooves from the rolling mechanism 100 and welding the bottle mouth and the base to the first end and the tail end of the rolling mechanism 100.

[0041] The welding station is provided with a positioning mechanism 200 for abutting against and stably clamping and centering the fire extinguisher bottle from both sides of the periphery thereof;

[0042] A blanking assembly 300 is arranged on the top of the welding station for supplying the bottle mouth and base to the fire extinguisher bottle body;

[0043] A feeding mechanism 500 is arranged on the bottom of the welding station for receiving and transferring the fire extinguisher bottle;

[0044] A laser welding gun 600 is arranged on one side of the welding station for welding the base and bottle body and the bottle mouth and bottle body;

[0045] The positioning mechanism 200 is provided with a coupling determination mechanism for determining the connection posture according to the preliminary connection track of the base and bottle mouth and bottle body, and is also provided with a correction mechanism for correcting the connection posture of the base and bottle mouth and bottle body.

[0046] The rolling mechanism 100 rolls and couples the bottle body, and after rolling out the coupling groove, the bottle body is transferred to the welding station. The welding station is provided with a blanking assembly 300 for blanking and butting and coupling the bottle mouth and base assembly to the two ends of the bottle body, and after completion, the positioning mechanism 200 arranged on the welding station clamps the bottle body, and the coupling determination mechanism on the positioning mechanism 200 determines the connection posture according to the preliminary connection track of the base and bottle mouth and bottle body, and the subsequent correction or direct transfer of the bottle body with coupling failure is carried out, and the welding is abandoned this time. After determining that the posture is normal, the laser welding gun 600 extends to the welding position after positioning to perform welding work.

[0047] After welding, the fire extinguisher bottle body is transferred out by the feeding mechanism 500.

[0048] As shown in Figure 2 The rolling mechanism 100 includes two moving seats 101 slidingly arranged on a slide rail, the two moving seats 101 are close to or away from each other through two-way driving cylinders 102, a cross beam is movably installed on the two moving seats 101 through a sliding assembly 105, and a connecting rod driving assembly 104 is arranged below the cross beam, and two rolling wheels 106 are arranged below the bottom of the connecting rod driving assembly 104 for rolling the two ends of the fire extinguisher bottle body;

[0049] The two moving seats 101 are each provided with a supporting seat 107 for clamping the fire extinguisher bottle body and can actively or passively carry the bottle body to rotate.

[0050] After the straight welding process is completed, the bottle body reaches the rolling station, and is placed on the rotating seat 108. The two moving seats 101 move towards each other to clamp and position the two ends of the bottle body. The bottle body is rotated to cooperate with the descending rolling wheel 106 to roll the two ends of the bottle body. The rolling wheel 106 is lowered through the connecting rod driving assembly 104, which includes a parallelogram connecting rod frame, a cylinder, and a guide mechanism for driving.

[0051] The top beam of the two moving seats 101 is designed to be fixed on one side, and the other end is located between the two moving seats 101 and is slidingly arranged, so that the two moving seats 101 can still maintain a horizontal state during simultaneous displacement.

[0052] As shown in Figure 1 and Figure 2 , one of the two moving seats 101 is provided with a driving member 103 for driving the supporting seat 107 to actively rotate. The rolling mechanism 100 further includes a rotating seat 108 arranged at the bottom for supporting and carrying the bottle body to rotate and transfer.

[0053] The two moving seats 101 are slidingly arranged on the slide rails below, and are driven by the two-way driving cylinder 102 to move towards each other or in the opposite direction, so as to clamp and position or release the bottle body. The rotating seat 108 is always supported at the bottom of the bottle body during rolling, and after the rolling of the bottle body is completed and the clamping is released, the rotating seat 108 is rotated to adjust the posture of the bottle body for transfer to the next welding station.

[0054] As shown in Figure 5 and Figure 7 , the feeding mechanism 500 is arranged on the lead screw assembly 800 for driving the reciprocating linear movement of the lead screw assembly 800. The lead screw assembly 800 is a double lead screw for driving a first receiving module composed of a support rod 501 and a rotating top assembly 502, and a second receiving module composed of a bottom receiving frame 503,

[0055] The first receiving module and the second receiving module move away from each other, and the second receiving module is used to receive the fire extinguisher bottle body from the rolling mechanism 100.

[0056] The first receiving module and the second receiving module are respectively used to receive and send the fire extinguisher bottle into and out of the welding station. The two can complete the transfer of the receiving relationship of the fire extinguisher bottle.

[0057] The bottom receiving frame 503 has an adaptive arc groove in the middle for centering the bottle body.

[0058] As shown in Figure 5 and Figure 6 , the support rod 501 and the rotating top assembly 502 are installed on the sliding seat, and the rotating top assembly 502 is composed of a cylinder and a supporting seat, and the supporting seat is movably connected with the end of the cylinder.

[0059] In the embodiment, the end of the top support seat and the cylinder is rotationally connected, which is used to match the rotation clamping at the bottle mouth to be able to rotate with the whole bottle body. The support rod 501 can be inserted forward along the bottle body, and initially does not contact the bottle body.

[0060] When the base and the bottle mouth two modules fall and are coupled at the front and rear ends of the bottle body, the base is relatively large in diameter and is supported between the two support rods 501, so that the base and the bottom receiving frame 503 can be separated from the receiving relationship and the receiving relationship is transferred to the support rod 501; after welding is completed, the two receiving modules are slid backward, so that the first receiving module takes out the fire extinguisher bottle backward, and the second receiving module receives a new fire extinguisher bottle to be welded from the rolling mechanism 100 forward.

[0061] After the base and the bottle mouth are coupled and connected to the bottle body, the positioning mechanism 200 clamps.

[0062] As shown in Figure 5 and Figure 6 The positioning mechanism 200 includes a moving seat two 201 and a lead screw assembly one 202, the moving seat two 201 is slidably installed on the lead screw assembly one 202, and the two moving seat two 201 are provided with clamping rollers 204 for clamping the fire extinguisher bottle body;

[0063] One of the moving seat two 201 is provided with an elastic air rod 205, the extension end of the elastic air rod 205 points to the two ends of the fire extinguisher bottle body, the end of the elastic air rod 205 is connected with a thimble 206, the thimble 206 abuts against the section of the bottle mouth and the base, and the moving seat two 201 is further provided with a displacement sensor 203, the outgoing line end of which is connected to the thimble 206.

[0064] The moving seat two 201 is driven to move to the bottle body by the lead screw assembly one 202, and finally the clamping roller 204 thereon can be supported on the bottle body, and the positioning of the bottle body is realized by the clamping rollers 204 on both sides. When the bottle body is driven to rotate, the clamping roller 204 can rotate together.

[0065] When the clamping roller 204 is supported on the bottle body, the thimble 206 can be released by the elastic air rod 205 and abut against the section of the bottle mouth or the base at both ends. The thimble 206 will translate when the posture difference occurs when the bottle mouth or the base is coupled at the front and rear ends of the bottle body. The thimble 206 is connected with the displacement sensor 203, and the above translation will be detected by the displacement sensor 203, and the size of the difference can be determined. The coupling correction can be performed according to the difference, or the fire extinguisher bottle can be directly moved out and the welding is abandoned.

[0066] The elastic air rod 205 is initially retracted in the detection process, and is released when the ejector pin 206 is supported to the bottle body, so that the ejector pin 206 is displaced to the elastic displacement section to the bottle opening or the cross section of the base.

[0067] As shown in Figure 6 Another moving seat two 201 is provided with a main delivery wheel set 207, the circumferential surface of the main delivery wheel set 207 is rollingly connected to the bottle body, and the moving seat two 201 is provided with a correction mechanism 208 at the end close to the base for knocking the edge of the fire extinguisher bottle base in the axial direction.

[0068] The correction mechanism 208 includes a one-way elastic air cylinder mounted on the moving seat two 201, and a hammer is fixed to the output end of the air cylinder through an L-shaped bracket.

[0069] The main delivery wheel set 207 is mainly composed of a motor, a belt pulley and a driving wheel, the driving wheel is driven by the motor, and the driving wheel is in rolling contact with the bottle body to control the rotation of the bottle body, cooperates with the clamping roller 204 and the positioning on both sides of the bottle body, and makes the bottle body rotate at a uniform speed around a single shaft to complete the detection and welding.

[0070] When the coupling posture between the bottle opening and the base module and the bottle body is determined to be abnormal by the ejector pin 206, the coupling posture can be corrected by knocking the edge of the base with a large span. The setting positions of the ejector pin 206 and the correction mechanism 208 are respectively at the two ends in the radial direction, the ejector pin 206 is directly released after being rotated by 180° at the maximum span, and the correction mechanism 208 is knocked to correct the inclined coupling posture. When the inclination angle is large and causes a large range of interlacing, the correction method cannot make the posture return to the normal state. When the ejector pin 206 still cannot return to the normal state after a certain number of turns, the fire extinguisher bottle to be processed is moved out by the feeding mechanism 500, the welding process is cancelled, and the next welding process is continued.

[0071] The elastic one-way air cylinder of the correction mechanism 208 is charged with air, and the internal elastic member is retracted after the electromagnetic valve is released to drive the knocking hammer to knock the base. Similarly, the correction mechanism 208 can also be arranged at the bottle opening to knock and correct the coupling posture, and the fitting angle of the knocking hammer and the bottle opening surface needs to be adjusted.

[0072] The impact surface of the knocking hammer is provided with a rubber layer to protect the bottle body.

[0073] As shown in Figure 4 and Figure 5 The processing equipment is also provided with a pushing mechanism 700, which is used to support the bottle body to the feeding mechanism 500 after the rotating seat 108 drives the bottle body to rotate.

[0074] After the rolling of the bottle body on the rolling mechanism 100, the moving seat 101 on both sides is withdrawn, the rotating seat 108 rotates to drive the fire extinguisher bottle to rotate 90°, and one end of the fire extinguisher bottle is directed to the pushing mechanism 700. The pushing mechanism 700 is actuated to extend outward, and the pushing mechanism 700 is pushed to the bottom receiving frame 503.

[0075] As shown in Figure 5 The unloading assembly 400 is controlled to ascend and descend by the top supporting cylinder at the bottom, and the unloading assembly 400 is used to carry the bottle mouth and the bottle body coupling in the unloading assembly 300.

[0076] The top supporting cylinder is connected to the mounting frame on the unloading assembly 400 through the connecting rod, the unloading assembly 400 includes the clamping device arranged at the front, which can directly accommodate the bottle mouth module, and the top supporting cylinder is arranged at the rear, which can support the bottle mouth module out of the coupling interface with the bottle body. The two unloading assemblies 300 shown in the figure are respectively used to store and deliver the bottle mouth and the base two modules, and a push-out cylinder 301 is arranged between the two unloading assemblies 300. The main function of the push-out cylinder 301 is to synchronously push out the stored bottle mouth and base in the two unloading assemblies 300, and the bottle mouth is supported into the clamping of the unloading assembly 400.

[0077] The base in the other unloading assembly 300 is directly pushed out, and the unloading assembly 300 includes two parts, which are composed of a storage unit and a guide-out unit. The storage unit is relatively long, and the guide-out unit is relatively short. The base is first pushed into the guide-out unit and then falls down. The support rod 501 arranged below receives and finally pushes to the fire extinguisher bottle body through the rotating top assembly 502 for coupling and interfacing.

[0078] The working principle and use process of the present application are as follows:

[0079] The rolling mechanism 100 rolls and couples the bottle body, and after the coupling groove is rolled out, the bottle body is transferred to the welding station. The unloading assembly 300 unloads the bottle mouth and the base downward, and the coupling and interfacing are completed through the unloading assembly 400 and the feeding mechanism 500. The positioning mechanism 200 on both sides approaches to determine the coupling posture, and the ejector pin 206 walks along the section of the bottle mouth and the base to measure the horizontal displacement. If the horizontal displacement exists, the posture is incorrect. Then the correction mechanism 208 is matched to correct, and the ejector pin 206 continues to determine while correcting. If the correct posture is returned, the welding work is performed, and if the posture cannot be corrected after a specified number of turns or the deviation is large at the beginning, the bottle body is directly moved out.

[0080] It is to be understood that the terminology used herein such as first and second, and the like, is only used to distinguish one entity or action from another entity or action, and does not necessarily require or imply any such actual relationship or order between such entities or actions.

[0081] While embodiments of the present application have been shown and described with reference to particular embodiments thereof, it will be understood by those skilled in the art that various changes in form and details can be made therein without departing from the spirit and scope of the application. The scope of the application is defined by the appended claims and their equivalents.
