Detailed Implementation

[0028] The following description, in conjunction with the accompanying drawings, further illustrates the automatic assembly equipment for level tubes according to this utility model.

[0029] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0030] See appendix Figure 1-7 As shown, this embodiment of an automatic assembly device for a spirit level tube is characterized by including an assembly support 1, a rotatable indexing plate 101 mounted on the assembly support 1, a motor 102 driving the indexing plate 101 to rotate, an elastic limiting seat 2 mounted on the indexing plate 101 to facilitate the placement of the spirit level tube, an unlocking structure 3 mounted on the assembly support 1 to facilitate the placement of the spirit level tube on the elastic limiting seat 2, a filling mechanism 4 for automatically filling the spirit level tube, and an automatic assembly mechanism 5 for automatically loading and assembling the tube cap; the elastic limiting seat 2 includes a product placement seat 201, a clamping plate 202 and a pushing plate 203 slidably mounted on both sides of the product placement seat 201, a slide rod 205 passing through the product placement seat 201 and connected to the clamping plate 202 and the pushing plate 203 respectively, and an elastic element 204 installed between the pushing plate 203 and the product placement seat 201; the unlocking structure 3 includes a side block 301 that pushes the pushing plate 203 to move and a drive side block 301 to move. The automatic assembly mechanism 5 for bubble tube caps includes a vibratory feeder 501 for automatically conveying bubble tube caps, a material distribution component 502 connected to the vibratory feeder 501 for distributing and conveying bubble tube caps, and an automatic assembly machine 503 for assembling bubble tube caps. The drive source 302 drives the side block 301 to move, the side block 301 pushes the push plate 203 to move, the push plate 203 drives the slide rod 205 to move along the product placement seat 201, and the slide rod 205 pushes the clamping plate 202 towards... The external movement compresses the elastic element 2045, allowing the empty level tube to be placed on the product placement seat 201. Then, the drive source 302 drives the side block 301 to move in the opposite direction, eliminating the pushing force of the push plate 203. The elastic element 204 automatically drives the push plate 203 to reset, which in turn drives the slide rod 205 to reset. The slide rod 205 then drives the clamping plate 202 to reset, clamping the empty level tube on the product placement seat 201, thus facilitating the placement of the empty level tube.

[0031] See appendix Figure 5 As shown, the filling mechanism 4 includes a filling support 401, a dispensing valve 402 mounted on the filling support 401, and a filling tube 403 communicating with the dispensing valve 402 to fill the bubble tube of the level. The dispensing valve 402 controls the filling tube 403 to fill the bubble tube of the level with liquid, thereby facilitating the control of the liquid volume in the bubble tube of the level.

[0032] See appendix Figure 6-7As shown, the automatic assembly machine 503 for assembling the bubble tube caps on the dispensing component 502 includes an assembly bracket 504, a first slide rail 505 rotatably mounted on the assembly bracket 504, a servo motor 506 driving the first slide rail 505 to rotate, and a cap suction nozzle 507 mounted on the first slide rail 505 to suck up the bubble tube caps using negative pressure; the assembly bracket 504 is also equipped with a second slide rail 508, a second slider 509 mounted on the second slide rail 508, and a component mounted on the second slider 509 that is connected to the first slide rail 504. 5. A first slider 510 is adapted; the assembly bracket 504 is also provided with a guide groove 511 for rotating and guiding the first slide rail 505; a connecting guide block 512 adapted to the guide groove 511 is installed between the first slide rail 505 and the servo motor 506; the material distribution assembly 502 includes a material distribution bracket 513, a material distribution block 514 slidably mounted on the material distribution bracket 513, and a first cylinder 515 for driving the material distribution block 514 to slide; the material distribution block 514 is provided with a material distribution groove 516; the material distribution bracket 513 is also equipped with a first cylinder 515 for rotating the first slide rail 505; the first slider 510 is adapted to the first slide rail 505 and the servo motor 506 ... There is a third guide rail 517 and a third slider 518 mounted on the third guide rail 517 and connected to the distribution block 514. The bubble tube caps are transported to the distribution assembly 502 by the vibratory feeder. The first bubble tube cap is pushed into the distribution trough 516 by the following bubble tube caps. Then, the first cylinder 515 drives the distribution block 514 to move forward along the third guide rail 517, transporting the bubble tube caps in the distribution trough 516 to the automatic assembly machine 503. Then, the cap suction nozzle 507 uses negative pressure to adsorb the bubble tube caps. Then, the servo motor 506 drives the connecting guide. Block 512 moves along guide groove 511, and connecting guide block 512 drives first slide rail 505 to move along guide groove 511. First slide rail 505 drives cap suction nozzle 507 to move. At the same time, during the movement of first slide rail 505 along guide groove 511, it drives second slider 509 to move along second slide rail 508 until cap suction nozzle 507 is above level bubble tube. Then cap suction nozzle 507 cancels negative pressure, allowing bubble tube cap to fall directly onto level bubble tube, thereby facilitating automated feeding and installation of bubble tube cap and improving installation material unloading.

[0033] See appendix Figure 8As shown, it also includes a cap detection mechanism 6 for detecting the installation of the bubble tube cap; the cap detection mechanism 6 includes a detection bracket 601, a detection block 602 slidably mounted on the detection bracket 601, a detection live bolt sleeve 603 mounted on the detection block 602, a photoelectric switch 604, and a second cylinder 605 for driving the detection block 602 to move; the detection bracket 601 is also equipped with a fourth slide rail 606 and a fourth slider 607 mounted on the fourth slide rail 606 and connected to the detection block 602; the second cylinder 605 drives the detection block 602 to move downward along the fourth slide rail 606, so that the detection live bolt sleeve 603 on the detection block 602 contacts the bubble tube cap. When the detection live bolt sleeve 603 does not move, the bubble tube cap is not installed on the level bubble tube. When the detection live bolt sleeve 603 is pushed to the photoelectric switch 604 and is sensed by the photoelectric switch 604, it indicates that the bubble tube cap is installed, thus facilitating automated sensing of whether the bubble tube cap is installed.

[0034] See appendix Figure 9 As shown, it also includes a pressing mechanism 7 that fully presses the bubble tube of the level into the elastic limiting seat 2; the pressing mechanism 7 includes a pressing bracket 701, a third cylinder 702 mounted on the pressing bracket 701, and a pressing block 703 connected to the third cylinder 702 to press the bubble tube of the level into the elastic limiting seat 2; by pushing the pressing block 703 downward by the third cylinder 702, the bubble tube of the level is fully pressed into the elastic limiting seat 2, thereby ensuring that the bubble tube of the level is fully installed in the elastic limiting seat 2 and preventing movement in subsequent steps that would affect normal assembly.

[0035] See appendix Figure 10-11 As shown, it also includes an ultrasonic welding mechanism 8 for welding bubble tube caps; the ultrasonic welding mechanism 8 includes a welding base 801, an ultrasonic welding machine 802 mounted on the welding base 801, and a bottom support structure 803 for supporting the bubble tube caps during welding; the bottom support structure 803 includes a support base 804, a support block 805 movably mounted on the support base 804, a drive block 806 for pushing the support block 805 to move, and a fourth cylinder 807 for driving the drive block 806 to move; the drive block 806 is provided with a guide slope 808 for driving the support block 805 to move upward; by the fourth cylinder 807 pushing the drive block 806 forward, the support block 805 is pushed upward along the guide slope 808 on the drive block 806 until the support block 805 is below the indexing plate 101, thereby facilitating the ultrasonic welding machine 802 to support it from the bottom during welding, improving the quality and efficiency of welding.

[0036] See appendix Figure 12As shown, it also includes a feeding mechanism 9 for automatically feeding the assembled level bubble tube; the feeding structure includes a feeding bracket 901, a sliding plate 902 slidably mounted on the feeding bracket 901, a fifth cylinder 903 for driving the sliding plate 902, a lifting plate 904 liftably mounted on the sliding plate 902, a clamping cylinder 905 mounted on the lifting plate 904 for clamping the level bubble tube, a sixth cylinder 906 for driving the lifting plate 904 to rise and fall, and a feeding mechanism 905 mounted on the assembly support 1 to facilitate the feeding of the level bubble tube. The tube feeding guide channel 907; the assembly support 1 is also equipped with a seventh cylinder 908 and a feeding unlocking plate 909 connected to the seventh cylinder 908; the feeding bracket 901 and the sliding plate 902 are respectively equipped with a fifth slide rail 910 and a sixth slide rail 911, and a fifth slider 912 and a sixth slider 913 respectively installed on the fifth slide rail 910 and the sixth slide rail 911 and connected to the sliding plate 902 and the lifting plate 904; the lifting plate 904 is driven by the sixth cylinder 906. Moving downwards along the sixth slide rail 911, the clamping cylinder 905 clamps the assembled level bulb. Then, the sixth cylinder 906 drives the lifting plate 904 to move upwards along the sixth slide rail 911. Simultaneously, the fifth cylinder 903 drives the sliding plate 902 to move. The sliding plate 902 moves the lifting plate 904 and the clamping cylinder 905 to above the unloading guide channel 907. Then, the sixth cylinder 906 drives the lifting plate 904 to move downwards along the sixth slide rail 911, and the clamping cylinder 905 releases the level bulb. The spirit level tube is placed on the unloading guide channel 907 and collected uniformly along the unloading guide channel 907, which facilitates automated unloading and improves unloading efficiency. The seventh cylinder 908 drives the unloading unlocking plate 909 to move, which pushes the push plate 203 on the elastic limit seat 2 to move. The push plate 203 pushes the clamping plate 202 to move outward, and at the same time, the elastic element 204 extends outward to release the spirit level tube, which makes it easier for the clamping cylinder 905 to clamp the spirit level tube.

[0037] The working process of this utility model is as follows: First, the drive source 302 drives the side block 301 to move. The side block 301 pushes the push plate 203 to move. The push plate 203 drives the slide rod 205 to move along the product placement seat 201. The slide rod 205 pushes the clamping plate 202 outward, and at the same time compresses the elastic element 2045. At this time, the empty level bubble tube can be placed on the product placement seat 201. Then, the drive source 302 drives the side block 301 to move in the opposite direction. The push plate 203 loses its pushing force. The elastic element 204 automatically drives the push plate 203 to reset. The push plate 203 drives the slide rod 205 to reset. The slide rod 205 drives the clamping plate 202 to reset, thus resetting the product placement seat. The empty spirit level tube on the product placement seat 201 is clamped. Then, the motor 102 drives the indexing plate 101 to rotate. The indexing plate 101 drives the elastic limit seat 2 to rotate to the pressing mechanism 7. Then, the third cylinder 702 pushes the pressing block 703 downward to completely press the spirit level tube into the elastic limit seat 2, thus ensuring that the spirit level tube is completely installed in the elastic limit seat 2. Then, the spirit level tube is transported to the filling mechanism 4 in the above manner. Then, the dispensing valve 402 opens to transport liquid into the spirit level tube through the filling pipe 403. After filling, the dispensing valve 402 closes. Then, the spirit level tube is transported to the automatic tube cap assembly mechanism 5. The process involves conveying the bubble tube caps to the dispensing assembly 502. The foremost bubble tube cap is pushed into the dispensing trough 516 by the following bubble tube caps. Then, the first cylinder 515 drives the dispensing block 514 to move forward along the third guide rail 517, conveying the bubble tube caps in the dispensing trough 516 to the automatic assembly machine 503. The cap suction nozzle 507 then uses negative pressure to suction the bubble tube caps. Next, the servo motor 506 drives the connecting guide block 512 to move along the guide groove 511. The connecting guide block 512 drives the first slide rail 505 to move along the guide groove 511. Simultaneously, the first slide rail 505 moves the cap suction nozzle 507. The second slider 509 is driven to move along the second slide rail 508 until the cap suction nozzle 507 is above the level tube. Then the negative pressure of the cap suction nozzle 507 is released, allowing the tube cap to fall directly onto the level tube. The level tube is then transported to the cap detection mechanism 6. The second cylinder 605 drives the detection block 602 to move downward along the fourth slide rail 606, so that the detection live bolt sleeve 603 on the detection block 602 contacts the tube cap. When the detection live bolt sleeve 603 does not move, the tube cap is not installed on the level tube. When the detection live bolt sleeve 603 is pushed to the photoelectric switch 604 and is sensed by the photoelectric switch 604, it indicates that the tube cap is installed.The spirit level tube is then transported to the ultrasonic welding mechanism 8. The fourth cylinder 807 pushes the drive block 806 forward, causing the support block 805 to rise along the guide ramp 808 on the drive block 806 until it reaches below the indexing plate 101. The ultrasonic welding machine 802 then ultrasonically welds the tube cap. The welded spirit level tube is then transported to the unloading mechanism 9. The seventh cylinder 908 drives the unloading unlocking plate 909, which in turn pushes the push plate 203 on the elastic limit seat 2. The push plate 203 pushes the clamping plate 202 outward, simultaneously causing the elastic element 204 to extend outward, thus releasing the spirit level tube. The sixth cylinder 906 drives the lifting plate 904 to move downward along the sixth slide rail 911, while the clamping cylinder 905 clamps the assembled level indicator bulb. Then, the sixth cylinder 906 drives the lifting plate 904 to move upward along the sixth slide rail 911. Simultaneously, the fifth cylinder 903 drives the sliding plate 902 to move. The sliding plate 902 moves the lifting plate 904 and the clamping cylinder 905 to above the unloading guide channel 907. Then, the sixth cylinder 906 drives the lifting plate 904 to move downward along the sixth slide rail 911, while the clamping cylinder 905 releases the level indicator bulb, placing it on the unloading guide channel 907 for unified collection.

[0038] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
