Description

Technical Field

[0001] This invention relates to the field of spring-loaded tube assembly technology, and particularly to a spring-loaded tube assembly device. Background Technology

[0002] To facilitate the assembly, disassembly, or expansion and contraction of multiple pipe fittings, a V-shaped spring with a ball bearing is usually installed inside the hollow pipe fitting. Positioning holes for the ball bearing to protrude are provided on the peripheral wall of the pipe fitting. During use, the ball bearing can be pressed into the pipe fitting, thereby enabling the assembly, disassembly, or expansion and contraction of multiple pipe fittings.

[0003] Existing spring-loaded fitting assembly equipment typically includes a fitting fixing mechanism, a spring-loaded feeding mechanism, and an assembly mechanism. The fitting fixing mechanism secures the fitting, the spring-loaded feeding mechanism feeds and installs the springs, and the assembly mechanism, located at the end of the spring-loaded feeding mechanism, pushes the springs into the fitting to assemble them. The spring-loaded feeding mechanism is usually arranged in a front-to-back direction. During feeding, multiple springs are arranged sequentially on the feeding mechanism, which transports them from front to back to the assembly mechanism. The assembly mechanism then pushes the spring at the very end of the feeding mechanism into the fitting. However, during this process, since the springs are continuously conveyed backward, when the assembly mechanism pushes the last spring, the other springs are still being conveyed backward. At this time, the springs are prone to falling backward. In addition, when the assembly mechanism pushes the springs, it cannot guarantee that it will accurately push only the last spring each time. There is a possibility that two springs will be pushed towards the pipe at the same time, which can easily lead to the failure of the spring and pipe assembly and seriously affect the assembly accuracy and assembly efficiency of the pipe spring assembly machine. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a spring-loaded tube assembly device, in which the assembly mechanism can accurately push and assemble the spring-loaded tube at the very end of the feeding mechanism, which is beneficial to improving the assembly accuracy and efficiency of the spring-loaded tube.

[0005] According to an embodiment of the present invention, a spring-loaded tube assembly device includes: a frame; a tube fixing mechanism disposed on the frame and used to fix the tube; a spring-loaded feeding mechanism arranged along the front-rear direction of the frame, the rear end of the spring-loaded feeding mechanism having a discharge end, the spring-loaded feeding mechanism being able to sequentially convey multiple spring-loaded pieces from front to back to the discharge end; an assembly mechanism including a pushing assembly arranged opposite to the tube fixing mechanism, the pushing assembly including a first driving device and a pushing member connected by transmission, the pushing member being disposed on the rear side of the spring-loaded feeding mechanism and offset from the discharge end in the left-right direction, the first driving device being able to drive the pushing member to move closer to or away from the tube fixing mechanism, the pushing member being used to push the spring-loaded pieces toward the tube fixing mechanism; and a transfer mechanism including a second... The machine includes a drive unit and a transfer plate. The transfer plate is sandwiched between the discharge end and the pusher. The transfer plate has a blocking part and a transfer part. The blocking part is located on the side of the transfer part away from the pusher. The transfer part has a transfer groove that can accommodate a spring piece. The second drive unit can drive the transfer plate to reciprocate in the left-right direction. The frame is also equipped with a top-feeding mechanism located in front of the pusher. When the transfer plate moves to the point where the transfer groove is aligned with the discharge end, the spring piece feeding mechanism can convey the spring piece from the discharge end into the transfer groove. When the transfer plate moves to the point where the transfer groove is aligned with the pusher, and the blocking part is near or abuts the discharge end, the top-feeding mechanism can push the spring piece in the transfer groove onto the pusher.

[0006] The spring-loaded tube assembly equipment according to embodiments of the present invention has at least the following beneficial effects:

[0007] In the spring-loaded tube assembly equipment of this invention, a transfer plate is provided, which has a transfer groove capable of accommodating one spring-loaded piece. Thus, when the transfer plate moves to the point where the transfer groove is aligned with the discharge end, the spring-loaded piece feeding mechanism can transport the spring-loaded piece from the discharge end into the transfer groove. This allows the spring-loaded piece at the very end of the spring-loaded piece feeding mechanism to be accurately transferred to the pusher, thereby enabling the assembly mechanism to accurately push and assemble the spring-loaded piece at the very end of the spring-loaded piece feeding mechanism. This avoids the situation where the assembly mechanism simultaneously pushes the two spring-loaded pieces at the very end of the spring-loaded piece feeding mechanism toward the tube, thereby greatly improving the assembly accuracy and efficiency of the spring-loaded piece and the tube. Furthermore, when the transfer plate moves to the position where it is aligned with the pusher, the blocking part approaches or abuts the discharge end. That is, when the transfer mechanism moves the spring from the discharge end to the pusher, the blocking part of the transfer plate approaches or abuts the discharge end, which can act as a material stopper, preventing other springs from falling from the discharge end after being transported there. This avoids the impact on the assembly efficiency of the spring fittings due to the need to pick up and rework fallen springs, thus facilitating the smooth assembly of fittings and springs and further improving the assembly efficiency of springs and fittings.

[0008] According to some embodiments of the present invention, the spring sheet includes a first elastic portion, a bent portion, and a second elastic portion. The bent portion is connected between the first elastic portion and the second elastic portion, and there is an included angle between the first elastic portion and the second elastic portion. A ball is protruding from the surface of the first elastic portion. The transfer groove includes a first clearance groove, a clamping groove, and a second clearance groove. The clamping groove is inclined from top to bottom toward the pipe fixing mechanism, and the thickness of the clamping groove is adapted to the thickness of the first elastic portion. The first clearance groove is located at the upper end of the clamping groove and is used to accommodate the ball on the surface of the spring sheet. The second clearance groove is located at the lower end of the clamping groove and is used to accommodate the bent portion.

[0009] According to some embodiments of the present invention, the ejector mechanism includes a third driving device and an ejector rod, the ejector rod being arranged in a front-rear direction, and the transfer groove further includes a third clearance groove adapted to the ejector rod; when the transfer plate moves to the point where the transfer groove is aligned with the pusher, the third driving device can drive the ejector rod to move to the third clearance groove and push the spring piece in the transfer groove onto the pusher.

[0010] According to some embodiments of the present invention, the pushing assembly further includes a support member fixedly installed on the frame and located on the upper side of the pushing member. The support member has a support surface that slopes downward toward the pipe fixing mechanism. When the top material mechanism pushes the spring in the transfer groove onto the pushing member, the support surface can support the inner surface of the spring. When the first driving device drives the pushing member to move relative to the support member and approach the pipe fixing mechanism, the pushing member can drive the spring to disengage from the support member and push the spring into the pipe of the pipe fixing mechanism.

[0011] According to some embodiments of the present invention, the outer surface of the spring sheet has outwardly protruding beads, and the assembly mechanism further includes a pressing component, which includes a fourth driving device and a pressing block connected in a transmission manner. The pressing block is located on the side of the pipe fixing mechanism near the pusher. When the first driving device drives the pusher to push the spring sheet to the opening of the inserted pipe, the beads abut against the periphery of the opening of the pipe. The fourth driving device can drive the pressing block to press down on the spring sheet and cause the spring sheet to compress and deform downward. The first driving device can continue to drive the pusher to push the spring sheet and beads into the inserted pipe.

[0012] According to some embodiments of the present invention, the pipe fixing mechanism includes an upper mold base and a lower mold base arranged opposite to each other in the vertical direction. The upper mold base and the lower mold base can move relative to each other closer or further apart. The lower surface of the upper mold base is provided with an upper pressure groove, and the upper surface of the lower mold base is provided with a lower pressure groove. The upper mold base is provided with a mounting hole communicating with the upper pressure groove, and a positioning pin is movably installed in the mounting hole. The side wall of the pipe is provided with a positioning hole for ejecting a ball. When the upper mold base and the lower mold base move relative to each other closer, the upper pressure groove and the lower pressure groove can cooperate to clamp the pipe. The positioning pin can move downward, protrude from the upper pressure groove, and be inserted into the positioning hole of the pipe. When the pusher pushes the spring into the pipe and causes the ball to move closer to the positioning hole, the positioning pin can move upward out of the positioning hole of the pipe and cause the ball to eject from the positioning hole.

[0013] According to some embodiments of the present invention, the upper mold base is equipped with a fifth driving device that is pulsatorically connected to the positioning pin, the fifth driving device being capable of driving the positioning pin to move in the vertical direction; the lower mold base is pulsatorically connected to a sixth driving device, the sixth driving device being capable of driving the lower mold base to move in the vertical direction closer to or away from the upper mold base.

[0014] According to some embodiments of the present invention, a feeding mechanism is further included, the feeding mechanism including a seventh driving device and a feeding rod connected by transmission, the feeding rod being disposed on the side of the pipe fixing mechanism near the pusher; when the pusher pushes the spring into the pipe and causes the ball to pop out from the positioning hole, the seventh driving device can drive the feeding rod to move closer to the upper pressure groove and push the pipe out of the upper pressure groove and the lower pressure groove.

[0015] According to some embodiments of the present invention, the pressing assembly further includes a support frame and a slide block. The support frame is mounted on the frame, and the slide block is slidably mounted on the support frame. The fourth driving device is mounted on the support frame and is drively connected to the slide block. The fourth driving device can drive the slide block to reciprocate in the up-down direction. The pressing block and the feeding mechanism are both mounted on the slide block and can follow the slide block to move in the up-down direction. When the slide block moves downward, the pressing block can press down against the spring sheet, allowing the pusher to push the ball into the tube. The feeding rod is aligned with the upper pressing groove and can be inserted between the upper pressing groove and the lower pressing groove.

[0016] According to some embodiments of the present invention, the spring feeding mechanism includes a vibratory feeder and a vibratory table. The vibratory table is arranged between the material transfer mechanism and the vibratory feeder in the front-back direction. The vibratory feeder is used to store springs and vibrate them sequentially onto the vibratory table. The discharge end is located at the end of the vibratory table away from the vibratory feeder. The vibratory table is capable of vibrating and conveying the springs and conveying each spring sequentially to the discharge end.

[0045] Reference Figures 1 to 12An embodiment of the present invention provides a spring-loaded tube assembly device, including a frame 100, a tube fixing mechanism 200, a spring-loaded feeding mechanism 300, an assembly mechanism, and a material transfer mechanism 500. The pipe fitting fixing mechanism 200 is mounted on the frame 100 and is used to fix the pipe fitting 950; the spring sheet feeding mechanism 300 is arranged along the front-rear direction of the frame 100, and the rear end of the spring sheet feeding mechanism 300 has a discharge end 310. The spring sheet feeding mechanism 300 can sequentially convey multiple spring sheets 900 from front to back to the discharge end 310; the assembly mechanism includes a pushing assembly 400 arranged opposite to the pipe fitting fixing mechanism 200. The pushing assembly 400 includes a first driving device 411 and a pushing member 410 connected by transmission. The pushing member 410 is located on the rear side of the spring sheet feeding mechanism 300 and is offset from the discharge end 310 in the left-right direction. The first driving device 411 can drive the pushing member 410 to move closer to or away from the pipe fitting fixing mechanism 200. The pushing member 410 is used to push the spring sheets 900 toward the pipe fitting fixing mechanism 200; the material transfer mechanism 500 includes a second driving device 511 and a material transfer plate 510 connected by transmission. The transfer plate 510 is clamped between the discharge end 310 and the pusher 410. The transfer plate 510 has a blocking part 520 and a transfer part. The blocking part 520 is located on the side of the transfer part away from the pusher 410. The transfer part has a transfer groove 530 that can accommodate a spring 900. The second drive device 511 can drive the transfer plate 510 to reciprocate in the left and right direction. The frame 100 is also provided with a top-loading mechanism 600. The top-loading mechanism 600 is located at The front side of the pusher 410; when the transfer plate 510 moves to the transfer groove 530 and the discharge end 310 are aligned, the spring sheet feeding mechanism 300 can transport the spring sheet 900 of the discharge end 310 into the transfer groove 530; when the transfer plate 510 moves to the transfer groove 530 and the pusher 410 are aligned, and the blocking part 520 is close to or abuts against the discharge end 310, the top material mechanism 600 can push the spring sheet 900 in the transfer groove 530 onto the pusher 410.

[0046] When assembling the spring clips 900 and the tube 950 using the spring clip assembly equipment of this embodiment, the tube 950 is fixed to the tube fixing mechanism 200. The spring clip feeding mechanism 300 sequentially feeds each spring clip 900 from front to back to the discharge end 310. The second driving device 511 drives the transfer plate 510 to move closer to the discharge end 310, aligning the transfer trough 530 with the discharge end 310. At this time, the spring clip feeding mechanism 300 can feed the spring clips 900 located at the discharge end 310 into the transfer trough 530. Then, the second driving device... The drive plate 510 is moved closer to the pusher 410 by the drive device 511, so that the transfer groove 530 is aligned with the pusher 410. At this time, the spring piece 900 located in the transfer groove 530 can be pushed onto the pusher 410 by the pusher mechanism 600. Then, the pusher 410 can be moved closer to the pipe fixing mechanism 200 by the first drive device 411, so that the pusher 410 can push the spring piece 900 toward the pipe fixing mechanism 200 and insert it into the pipe 950 fixed to the pipe fixing mechanism 200. Thus, the assembly of the pipe 950 and the spring piece 900 can be completed.

[0047] During the assembly process of the aforementioned pipe fitting 950 and spring sheet 900, by setting up a transfer plate 510, when the transfer plate 510 moves to the point where the transfer groove 530 is aligned with the discharge end 310, the spring sheet feeding mechanism 300 can transport the spring sheet 900 from the discharge end 310 into the transfer groove 530. This allows the spring sheet 900 at the very end of the spring sheet feeding mechanism 300 to be accurately transferred to the pusher 410, thereby enabling the assembly mechanism to accurately push and assemble the spring sheet 900 at the very end of the spring sheet feeding mechanism 300. This avoids the situation where the assembly mechanism simultaneously pushes the two spring sheets 900 at the very end of the spring sheet feeding mechanism 300 toward the pipe fitting 950, thus greatly improving the assembly accuracy and efficiency of the spring sheet 900 and the pipe fitting 950. Furthermore, when the transfer plate 510 moves to the position where the transfer trough 530 is aligned with the pusher 410, the blocking part 520 approaches or abuts against the discharge end 310. That is, when the transfer mechanism 500 transfers the spring piece 900 from the discharge end 310 to the pusher 410, the blocking part 520 of the transfer plate 510 approaches or abuts against the discharge end 310, thereby playing a blocking role and preventing other spring pieces 900 from falling from the discharge end 310 after being transported to it. This avoids the impact on the assembly efficiency of the spring piece 900 and the fitting 950 due to the need to pick up and rework the fallen spring pieces 900, which is conducive to the smooth assembly of the fitting 950 and the spring piece 900 and further improves the assembly efficiency of the spring piece 900 and the fitting 950.

[0048] Understandably, referring to Figures 4 to 9To prevent the spring 900 from falling out of the gap between the discharge end 310 and the transfer plate 510 when it is conveyed from the discharge end 310 to the transfer trough 530, the distance between the discharge end 310 and the transfer plate 510 in the front-to-back direction should be less than the width of the spring 900. That is, the distance between the blocking part 520 and the discharge end 310 in the front-to-back direction should be less than the width of the spring 900. This can also effectively prevent the spring 900 of the discharge end 310 from continuing to be conveyed backward and falling out during the transfer process. Specifically, the distance between the discharge end 310 and the transfer plate 510 in the front-to-back direction can be set to 0, that is, the transfer plate 510 slides against the discharge end 310, so that when the transfer mechanism 500 moves the spring 900 of the discharge end 310 to the pusher 410, the blocking part 520 of the transfer plate 510 abuts against the discharge end 310, thereby effectively preventing other springs 900 from continuing to be conveyed backward from the discharge end 310 and falling down.

[0049] Understandably, referring to Figures 4 to 9 To prevent the spring 900 from falling out of the gap between the transfer plate 510 and the pusher 410 when it is transferred from the transfer groove 530 to the pusher 410, the distance between the transfer plate 510 and the pusher 410 in the front-back direction should be less than the width of the spring 900.

[0050] It is understood that the first drive device 411 and the second drive device 511 may specifically adopt linear drive structures such as cylinders and electric push rods, and the present invention does not specifically limit them.

[0051] Reference Figure 1 In some embodiments, the spring 900 includes a first elastic portion 910, a bent portion 930, and a second elastic portion 920. The bent portion 930 connects the first elastic portion 910 and the second elastic portion 920, and there is an included angle between the first elastic portion 910 and the second elastic portion 920. A ball 940 protrudes from the outer surface of the first elastic portion 910. Thus, during assembly, the first elastic portion 910 and the second elastic portion 920 can deform and move closer to each other under external compression through the bent portion 930, thereby reducing the included angle between the first elastic portion 910 and the second elastic portion 920, allowing the spring 900 to be smoothly inserted into the tube 950.

[0052] Reference Figures 4 to 9 In some embodiments, the transfer groove 530 includes a first relief groove 531, a clamping groove 534 and a second relief groove 532. The clamping groove 534 is inclined from top to bottom toward the pipe fixing mechanism 200, and the thickness of the clamping groove 534 is adapted to the thickness of the first elastic part 910. The first relief groove 531 is located at the upper end of the clamping groove 534 and is used to accommodate the ball 940. The second relief groove 532 is located at the lower end of the clamping groove 534 and is used to accommodate the bending part 930.

[0053] By adopting the above structure, the first clearance groove 531, the clamping groove 534 and the second clearance groove 532 can effectively clamp and limit the spring piece 900 and prevent the spring piece 900 from falling from the lower end of the transfer groove 530, thereby making the transfer of the spring piece 900 more stable.

[0054] It is understandable that, in addition to setting the transfer groove 530 to the above structure, the transfer groove 530 may also include a receiving groove adapted to the second elastic part 920, thereby making the shape of the entire transfer groove 530 compatible with the entire spring 900, and thus enabling stable transfer of the spring 900.

[0055] Reference Figure 4 and Figure 5 In some embodiments, the top material mechanism 600 includes a third drive device 611 and a top material rod 610, the top material rod 610 being arranged in the front-back direction, and the transfer groove 530 further includes a third clearance groove 533 adapted to the top material rod 610; when the transfer plate 510 moves to the transfer groove 530 and is aligned with the pusher 410, the third drive device 611 can drive the top material rod 610 to move to the third clearance groove 533 and push the spring piece 900 in the transfer groove 530 onto the pusher 410.

[0056] In the above structure, the setting of the third clearance groove 533 enables the top material rod 610 to move accurately into the transfer groove 530 and accurately push the spring piece 900 in the transfer groove 530 onto the pusher 410, thereby making the transfer of the spring piece 900 faster and more accurate.

[0057] It is understood that the third drive device 611 may specifically adopt a linear drive structure such as a cylinder or an electric push rod, and the present invention does not specifically limit it.

[0058] Understandably, referring to Figure 4 and Figure 5 In some embodiments, there are two push rods 610, and the transfer groove 530 is provided with two third clearance holes corresponding to the push rods 610. The arrangement of two push rods 610 can make the pushing force on the spring piece 900 more balanced, avoiding the situation where the spring piece 900 is not accurately transferred to the pusher 410 due to angular deviation when it is transferred from the transfer groove 530 to the pusher 410, thus making the transfer of the spring piece 900 more stable. It should be noted that the number of push rods 610 can be two, one, three, four or more, and the present invention does not make a specific limitation on this.

[0059] It is understood that the third relief groove 533 can be directly set in the first relief groove 531 or designed with the same groove structure as the first relief groove 531, that is, the push rod 610 can be directly moved into the first relief groove 531 and push the ball 940. Alternatively, the third relief groove 533 can also be directly set in the second relief groove 532 or designed with the same groove structure as the second relief groove 532, that is, the push rod 610 can be directly moved into the second relief groove 532 and push the bent part 930. The present invention does not specifically limit this.

[0060] Understandably, referring to Figure 4 and Figure 5 In some embodiments, the ejector mechanism 600 further includes a guide block 620, which has a guide hole corresponding to the ejector rod 610. The third driving device 611 can drive the ejector rod 610 to move through the guide hole and into the third clearance groove 533, thereby pushing the spring piece 900 in the transfer groove 530 onto the pusher 410. The guide block 620 can guide and limit the movement of the ejector rod 610, preventing the ejector rod 610 from shifting position during movement and failing to move accurately into the third clearance groove 533, thereby improving the accuracy of the ejector rod 610 pushing the spring piece 900.

[0061] Reference Figures 4 to 9 In some embodiments, the pusher assembly 400 further includes a support member 420 fixedly installed on the frame 100 and located on the upper side of the pusher member 410. The support member 420 has a support surface 421 that slopes downward toward the pipe fixing mechanism 200. When the top material mechanism 600 pushes the spring piece 900 in the transfer groove 530 onto the pusher member 410, the support surface 421 can support the inner surface of the spring piece 900. When the first driving device 411 drives the pusher member 410 to move relative to the support member 420 and approach the pipe fixing mechanism 200, the pusher member 410 can drive the spring piece 900 to disengage from the support member 420 and push the spring piece 900 into the pipe 950 of the pipe fixing mechanism 200.

[0062] In the above structure, the support member 420 can stably support the spring 900 during its movement, preventing the spring 900 from falling off. When the first driving device 411 drives the pusher 410 to move closer to the pipe fixing mechanism 200, the pusher 410 moves relative to the support member 420 and drives the spring 900 to disengage from the support member 420, so that the pusher 410 can easily push the spring 900 into the pipe 950.

[0063] Understandably, the support surface 421 can support the inner surface of the spring piece 900. Specifically, the spring piece 900 includes a first elastic portion 910, a bent portion 930, and a second elastic portion 920. The bent portion 930 connects the first elastic portion 910 and the second elastic portion 920, and there is an included angle between the first elastic portion 910 and the second elastic portion 920. A ball 940 is protruding from the outer surface of the first elastic portion 910. When the spring piece 900 moves from the transfer groove 530 to the support member 420, the support surface 421 can specifically support the side surface of the first elastic portion 910 facing the second elastic portion 920.

[0064] Reference Figure 4 and Figure 5 In some embodiments, the material transfer mechanism 500 further includes a first limiting plate 540 and a second limiting plate 550 arranged at intervals along the front-back direction. The first limiting plate 540 is fixedly installed on the frame 100 and slides against the side of the material transfer plate 510 away from the discharge end 310. Thus, when the material transfer plate 510 moves to the point where the material transfer trough 530 is aligned with the discharge end 310, the spring sheet feeding mechanism 300 conveys the spring sheet 900 located at the discharge end 310 into the material transfer trough 530. At this time, the first limiting plate 540 can limit the spring sheet 900 to prevent the spring sheet 900 from falling off the rear side of the material transfer trough 530, thereby enabling the spring sheet 900 to be stably conveyed into the material transfer trough 530 and move with the material transfer plate 510. The second limiting plate 550 is fixedly installed on the frame 100 and slides against the side of the pusher 410 away from the transfer plate 510, so that the pusher 410 is slidably clamped between the first limiting plate 540 and the second limiting plate 550. The first limiting plate 540 is also provided with a clearance notch on the side of the pusher 410 that allows the spring sheet 900 to move from the transfer groove 530 to the pusher 410. Therefore, the second limiting plate 550 can limit the spring piece 900, preventing it from falling off the rear side of the pusher 410 when it moves from the transfer groove 530 to the pusher 410. Furthermore, the first limiting plate 540 and the second limiting plate 550 can also cooperate to limit the pusher 410, ensuring that it can only move left and right between the first limiting plate 540 and the second limiting plate 550, approaching or moving away from the pipe fitting fixing mechanism 200. This reduces the risk of positional deviation during movement, improves the accuracy of the assembly of the pipe fitting 950 and the spring piece 900, and thus improves the assembly efficiency. In addition, the support member 420 can be fixedly installed between the first limiting plate 540 and the second limiting plate 550, facilitating its installation and ensuring it is stably installed above the pusher 410 and provides stable support for the spring piece 900.

[0065] Reference Figure 4 and Figure 5In some embodiments, the material transfer mechanism 500 further includes a mounting bracket 560 mounted on the frame 100. The first limiting plate 540 and the second limiting plate 550 are both mounted on the mounting bracket 560, the second driving device 511 is also mounted on the mounting bracket 560, and the material transfer plate 510 is mounted on the output end of the second driving device 511. Therefore, the mounting bracket 560 facilitates the installation layout of the first limiting plate 540, the second limiting plate 550, and the material transfer plate 510, making the structure of the spring-loaded tube assembly equipment more compact and stable.

[0066] Reference Figure 4 and Figure 5 In some embodiments, a connector 430 is installed at the output end of the first drive device 411. One end of the connector 430 extends between the first limiting plate 540 and the second limiting plate 550. The pusher 410 is installed at the end of the connector 430 that extends between the first limiting plate 540 and the second limiting plate 550. This allows the pusher 410 to be conveniently confined between the first limiting plate 540 and the second limiting plate 550, making the connection between the pusher assembly 400 and the transfer mechanism 500 more compact and facilitating the installation layout of each component.

[0067] Reference Figures 1 to 11 In some embodiments, the outer surface of the spring 900 is provided with an outwardly protruding ball 940. The assembly mechanism also includes a pressing component 700, which includes a fourth driving device 711 and a pressing block 710 connected by a transmission. The pressing block 710 is located on the side of the pipe fixing mechanism 200 near the pusher 410. When the first driving device 411 drives the pusher 410 to push the spring 900 to the opening of the inserted pipe 950, the ball 940 abuts against the periphery of the opening of the pipe 950. The fourth driving device 711 can drive the pressing block 710 to press down against the spring 900 and cause the spring 900 to be compressed and deformed downward. The first driving device 411 can continue to drive the pusher 410 to push the spring 900 and the ball 940 into the inserted pipe 950.

[0068] In the above structure, the pressing component 700 can press the spring 900 downward when the spring 900 is inserted into the opening of the tube 950, so that the spring 900 is compressed to the size that the ball 940 can also be inserted into the opening. This makes it convenient for the pusher 410 to push the entire spring 900 and the ball 940 into the tube 950.

[0069] Understandably, referring to Figures 1 to 11The spring 900 includes a first elastic part 910, a bending part 930, and a second elastic part 920. The bending part 930 connects the first elastic part 910 and the second elastic part 920, and there is an included angle between the first elastic part 910 and the second elastic part 920. A ball 940 is protruding from the outer surface of the first elastic part 910. Therefore, during the assembly process, the pressing component 700 can press the first elastic part 910 downward, so that the first elastic part 910 can bend downward through the bending part 930 and approach the second elastic part 920 under the pressing action of the pressing component 700. This reduces the included angle between the first elastic part 910 and the second elastic part 920, thereby allowing the spring 900 and the ball 940 to be smoothly inserted into the tube 950.

[0070] It is understood that the fourth drive device 711 may specifically adopt a linear drive structure such as a cylinder or an electric push rod, and the present invention does not specifically limit it in this regard.

[0071] Reference Figure 10 and Figure 11 In some embodiments, the pipe fixing mechanism 200 includes a lower mold base 220 and an upper mold base 210 arranged opposite each other in the vertical direction. The upper mold base 210 and the lower mold base 220 can move closer or further apart relative to each other. The lower surface of the upper mold base 210 is provided with an upper pressing groove 211, and the upper surface of the lower mold base 220 is provided with a lower pressing groove 221. The upper mold base 210 is provided with a mounting hole communicating with the upper pressing groove 211, and a positioning pin 230 is movably installed in the mounting hole. The side wall of the pipe fitting 950 is provided with a positioning hole 9 for ejecting a ball 940. 51. When the upper mold base 210 and the lower mold base 220 move closer to each other, the upper pressure groove 211 and the lower pressure groove 221 can cooperate to clamp the tube 950. The positioning pin 230 can move downward and protrude out of the upper pressure groove 211 and be inserted into the positioning hole 951 of the tube 950. When the pusher 410 pushes the spring 900 into the tube 950 and causes the ball 940 to move closer to the positioning hole 951, the positioning pin 230 can move upward out of the positioning hole 951 of the tube 950 and cause the ball 940 to pop out from the positioning hole 951.

[0072] In the above structure, the pipe fitting 950 can be clamped and fixed by the upper mold base 210 and the lower mold base 220. The upper mold base 210 and the lower mold base 220 can be moved closer to each other and the pipe fitting 950 can be placed in the upper pressure groove 211 and the lower pressure groove 221. The operation is convenient and the clamping is stable. In addition, the positioning pin 230 can be used to position the pipe fitting 950 at an angle. Since the ball bearing 940 is arranged facing upwards when the spring piece 900 is inserted, when fixing the pipe fitting 950, the positioning pin 230 is moved downwards until it protrudes from the upper pressure groove 211 and is inserted into the positioning hole 951 of the pipe fitting 950. This makes the positioning hole 951 of the pipe fitting 950 face upwards. This makes it easier for the ball bearing 940 to gradually move closer to the positioning hole 951 and finally pop out from the positioning hole 951 after the spring piece 900 and the ball bearing 940 are moved into the pipe fitting 950. This makes the assembly of the pipe fitting 950 and the spring piece 900 more accurate and faster, and thus makes the assembly of the pipe fitting 950 and the spring piece 900 more efficient.

[0073] Reference Figure 10 and Figure 11 In some embodiments, the upper mold base 210 is equipped with a fifth driving device 231 that is pulsatorically connected to the positioning pin 230. The fifth driving device 231 can drive the positioning pin 230 to move in the up-down direction. The lower mold base 220 is pulsatorically connected to a sixth driving device 222, which can drive the lower mold base 220 to move in the up-down direction closer to or away from the upper mold base 210.

[0074] In the above structure, by installing the fifth drive device 231 on the upper mold base 210, the positioning pin 230 can be easily driven to move up and down. By connecting the sixth drive device 222 to the lower mold base 220, the lower mold base 220 can be easily driven to move upward toward or away from the upper mold base 210 to clamp or release the pipe fitting 950. Specifically, when fixing the pipe fitting 950, the pipe fitting 950 is placed between the upper pressure groove 211 and the lower pressure groove 221. The fifth drive device 231 can drive the positioning pin 230 to move downward, protruding out of the upper pressure groove 211 and inserting into the positioning hole 951. The sixth drive device 222 can drive the lower mold base 220 to move upward toward the upper mold base 210 to clamp and fix the pipe fitting 950, thereby positioning and clamping the pipe fitting 950. After the tube 950 is clamped, the fifth drive device 231 can drive the positioning pin 230 to move upward and disengage from the positioning hole 951 of the tube 950, which makes it easier for the subsequent ball 940 to pass through the positioning hole 951, thereby facilitating the smooth assembly of the tube 950 and the spring 900.

[0075] Furthermore, by installing the fifth drive device 231 for driving the positioning pin 230 to move up and down on the upper mold base 210, and by connecting the sixth drive device 222 for realizing the relative movement between the upper mold base 210 and the lower mold base 220 to the lower mold base 220, the fifth drive device 231 and the sixth drive device 222 are respectively located on the upper mold base 210 and the lower mold base 220, thereby facilitating the installation and layout of the fifth drive device 231 and the sixth drive device 222.

[0076] It is understood that both the fifth drive device 231 and the sixth drive device 222 can adopt linear drive structures such as cylinders, electric push rod mechanisms, and linear motors, and the present invention does not specifically limit them.

[0077] It is understandable that, in order to achieve the up and down movement of the positioning pin 230, in addition to using the fifth driving device 231, in some embodiments, an elastic element can also be provided between the positioning pin 230 and the upper mold base 210. The elastic force of the elastic element is less than that of the spring sheet 900. When fixing the tube 950, the positioning pin 230 protrudes downward from the upper pressure groove 211 and passes through the positioning hole 951 of the tube 950. When the spring sheet 900 and the ball 940 move into the tube 950, the ball 940 can gradually move closer to the positioning hole 951. The ball 940 can abut against the positioning pin 230 and push the positioning pin 230 upward under the elastic force of the spring sheet 900. The elastic element is compressed under the pushing force of the ball 940, so that the positioning pin 230 can move upward out of the positioning hole 951. Thus, the ball 940 can pass out of the positioning hole 951, completing the assembly of the spring sheet 900 and the tube 950.

[0078] Reference Figure 10 and Figure 11 In some embodiments, a feeding mechanism 800 is also included. The feeding mechanism 800 includes a seventh drive device 811 and a feeding rod 810 that are connected by a transmission. The feeding rod 810 is located on the side of the pipe fixing mechanism 200 near the pusher 410. When the pusher 410 pushes the spring 900 into the pipe 950 and causes the ball 940 to pop out from the positioning hole 951, the seventh drive device 811 can drive the feeding rod 810 to move closer to the upper pressure groove 211 and push the pipe 950 out of the upper pressure groove 211 and the lower pressure groove 221.

[0079] In the above structure, the unloading mechanism 800 includes a seventh drive device 811 and an unloading rod 810 connected by a transmission. After the spring sheet 900 and the tube 950 are assembled, the seventh drive device 811 can drive the unloading rod 810 to move closer to the upper pressure groove 211 and push the tube 950 out from between the upper pressure groove 211 and the lower pressure groove 221, thereby completing the unloading. The structure is simple and the operation is convenient. In addition, since the upper mold base 210 is fixedly installed on the frame 100 and the lower mold base 220 is movably installed on the frame 100 through the sixth drive device 222, the accuracy of the unloading rod 810 pushing the tube 950 can be ensured by moving the unloading rod 810 closer to the upper pressure groove 211 during the unloading process.

[0080] Reference Figure 10 and Figure 11 In some embodiments, the pressing assembly 700 further includes a support frame 730 and a slide 731. The support frame 730 is mounted on the frame 100, and the slide 731 is slidably mounted on the support frame 730. A fourth drive device 711 is mounted on the support frame 730 and is connected to the slide 731 in a transmission manner. The fourth drive device 711 can drive the slide 731 to reciprocate in the up-down direction. The pressing block 710 and the feeding mechanism 800 are both mounted on the slide 731 and can move with the slide 731 in the up-down direction. When the slide 731 moves downward, the pressing block 710 can press down against the spring 900, so that the pusher 410 can push the ball 940 into the tube 950. The feeding rod 810 is aligned with the upper pressing groove 211 and can be inserted between the upper pressing groove 211 and the lower pressing groove 221.

[0081] In the above structure, by setting a support frame 730 and a slide 731, the fourth drive device 711 is mounted on the support frame 730 and connected to the slide 731 for transmission. The pressure block 710 and the feeding mechanism 800 are both mounted on the slide 731. Thus, the fourth drive device 711 can drive the pressure block 710 and the feeding mechanism 800 to move up and down simultaneously. When the pressure block 710 moves to press down against the spring 900 and allows the pusher 410 to push the ball 940 into the tube 950, the lower... The feeding rod 810 of the feeding mechanism 800 is aligned with the upper pressure groove 211. Thus, after the pusher 410 pushes the spring 900 and the ball 940 into the tube 950 and causes the ball 940 to pop out from the positioning hole 951 of the tube 950, the feeding rod 810 can be driven by the seventh drive device 811 to move closer to the upper pressure groove 211 and insert between the upper pressure groove 211 and the lower pressure groove 221, so that the tube 950 can be smoothly pushed out from between the upper pressure groove 211 and the lower pressure groove 221. After the pipe fitting 950 is ejected, the seventh drive device 811 drives the unloading rod 810 to move out between the upper pressure groove 211 and the lower pressure groove 221. Then, the fourth drive device 711 drives the pressure block 710 and the unloading mechanism 800 to move upward synchronously. This leaves enough space between the pipe fitting fixing mechanism 200 and the assembly mechanism, and allows the pusher 410 to make way for the movement of the pusher 410 during the process of pushing the spring 900 to move closer to the pipe fitting fixing mechanism 200 and the pusher 410 moving and resetting. This avoids interference and collision between the pusher 410 and the pressure block 710 or the unloading mechanism 800, making the assembly of the spring 900 and the pipe fitting 950 smoother and more stable.

[0082] Furthermore, by mounting the pressing assembly 700 and the feeding mechanism 800 together, and driving the pressing block 710 and the feeding mechanism 800 to move up and down synchronously via the fourth drive device 711, the structural compactness of the spring tube assembly equipment can be improved, and the installation layout of each component can be facilitated.

[0083] Understandably, the feeding mechanism 800 is mounted on the slide 731. Specifically, the seventh drive device 811 is fixedly mounted on the slide 731, and the feeding rod 810 is mounted on the output end of the seventh drive device 811.

[0084] Understandably, referring to Figure 10 and Figure 11In some embodiments, a first extension rod 720 and a second extension rod 820 are installed on the slide 731. A pressure block 710 is installed at the end of the first extension rod 720 away from the slide 731, and a feeding rod 810 is installed at the end of the second extension rod 820 away from the slide 731. The arrangement of the first extension rod 720 and the second extension rod 820 makes the pressure block 710 and the feeding rod 810 located in the vertical plane where the central axis of the upper pressure groove 211 is located. Thus, when the slide 731 drives the first extension rod 720 and the second extension rod 820 to move downward, the pressure block 710 can press down against the spring piece 900, and the feeding rod 810 can be arranged coaxially with the upper pressure groove 211 to facilitate the feeding operation of the pipe 950. The first extension rod 720 and the second extension rod 820 can further make way for the pusher 410, avoiding interference and collision caused by the support frame 730, the slide 731 and other mechanisms on the slide 731 on the movement of the pusher 410, thereby making the assembly of the spring 900 and the tube 950 smoother and more stable.

[0085] Reference Figures 1 to 12 In some embodiments, the spring feeding mechanism 300 includes a vibratory plate 320 and a vibratory table 330. The vibratory table 330 is arranged in the front-back direction between the material transfer mechanism 500 and the vibratory plate 320. The vibratory plate 320 is used to store the spring pieces 900 and vibrate the spring pieces 900 sequentially onto the vibratory table 330. The discharge end 310 is located at the end of the vibratory table 330 away from the vibratory plate 320. The vibratory table 330 can vibrate and transport the spring pieces 900 and transport each spring piece 900 sequentially to the discharge end 310.

[0086] In the above structure, by setting the feeding mechanism as a vibratory feeder 320 and a vibratory table 330, the vibratory feeder 320 can convey each piece 900 sequentially to the vibratory table 330 through vibration. The vibratory table 330 is arranged in the front-back direction and can convey each piece 900 sequentially to the discharge end 310 through vibration, and the piece 900 at the discharge end 310 can be conveyed to the transfer groove 530 of the transfer plate 510. The structure is simple and the conveying is convenient.

[0087] Reference Figures 1 to 12In some embodiments, the spring sheet 900 includes a first elastic portion 910, a bent portion 930, and a second elastic portion 920. The bent portion 930 is connected between the first elastic portion 910 and the second elastic portion 920, and there is an included angle between the first elastic portion 910 and the second elastic portion 920. The vibration table 330 is provided with a bearing surface 331 adapted to the first elastic portion 910 and the bent portion 930. The bearing surface 331 is arranged downwardly along the direction close to the pipe fixing mechanism 200, thereby enabling stable bearing of the spring sheet 900. A limit rod 340 is also provided on the side of the vibration table 330 close to the pipe fixing mechanism 200. The limit rod 340 is arranged at intervals from the vibration table 330. The bent portion 930 of the spring sheet 900 is located between the limit rod 340 and the vibration table 330, thereby preventing the spring sheet 900 from falling downwards and facilitating the stable transport of the spring sheet 900. Furthermore, a pressing component 350 is installed above the vibrating table 330, mounted on the limiting rod 340 and pressing against the vibrating table 330. The pressing component 350 has a limiting part 351 that extends downward and is spaced apart from the bearing surface 331. The first elastic part 910 of the spring sheet 900 can move below the limiting part 351 during the conveying process. Thus, the cooperation between the limiting rod 340 and the pressing component 350 can further ensure the stable conveying of the spring sheet 900.

[0088] It is understood that, in addition to using a vibration table 330, a conveyor belt or other conveying structure can also be used for conveying the spring sheet 900, and the present invention does not specifically limit this.

[0089] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings.
