[0030] Example 1:
[0031] Specifically, as Figures 1 to 12As shown, a non-vacuum tire and rim assembly line includes a tire conveying line 1, a rim conveying line 2 arranged below the tire conveying line 1, and a rim transfer line 3 arranged in a staggered manner with the rim conveying line 2, and further includes:
[0032] An automatic centering and sizing mechanism 4 is arranged on one side of the rim transfer line 3 close to the rim conveying line 2.
[0033] A tire and rim assembly mechanism 5 is arranged on one side of the rim transfer line 3 close to the rim conveying line 2.
[0034] A moving disc 6 is slidably connected to the rim transfer line 3 through two groups of guide rails.
[0035] The tire and rim assembly mechanism 5 includes a chassis 51 arranged below the rim transfer line 3, a lifting assembly 52 arranged on the chassis 51, a bearing assembly 53 arranged on one side of the chassis 51, and an inclined air cylinder 54 hingedly connected to the chassis 51.
[0036] It should be noted that the present scheme focuses on the tire and rim assembly link, connects the previous processing and subsequent assembly, integrates mechanical structure design, pneumatic control and electrical automation control technology, and realizes efficient and accurate assembly of non-vacuum tires and rims. It is suitable for automobile production factories, tire repair sites, automobile parts distribution centers and other places, and can meet the needs of large-scale batch production and small-batch multi-specification personalized assembly. It is a specific application of intelligent manufacturing technology in the field of automobile parts assembly.
[0037] The lifting assembly 52 includes a cylinder connecting plate 521, a lower cylinder 522 arranged at the bottom of the cylinder connecting plate 521, a lower cylinder limiting column 523 arranged on the cylinder connecting plate 521, a lower connecting plate 524 arranged on the lower cylinder limiting column 523, a rim bracket 525 fixedly arranged on the lower connecting plate 524, and a limiting rod 526 arranged on both sides of the lower connecting plate 524 and penetrating the cylinder connecting plate 521.
[0038] The piston rod of the lower cylinder 522 is connected to the bottom of the rim bracket 525 in sequence through the cylinder connecting plate 521, the lower cylinder limiting column 523, and the lower connecting plate 524.
[0039] The bearing assembly 53 includes two groups of side supports 531 fixedly arranged on the chassis 51, an annular support plate 532 rotatably connected to the two groups of side supports 531 through a bearing center shaft, a rotating roller 533 arranged along the circumference of the annular support plate 532, and four groups of support units 534 arranged along the circumference of the annular support plate 532.
[0040] The support unit 534 includes a support cylinder 5341 installed at the bottom of the annular support plate 532, a slider 5343 slidably connected to the annular support plate 532 through a slide seat 5342, and a connector 5344 for connecting the support cylinder 5341 and the slider 5343.
[0041] Specific working steps:
[0042] Step 1: The entire tire and rim assembly mechanism is assembled on the assembly frame. The tire is transported from the tire conveyor line 1 to the assembly pallet. The forward roller is an unpowered roller whose main function is to reduce the friction of the tire on the assembly pallet. After the tire arrives at the assembly station, it is manually rotated so that the valve is directly in front. During the rotation of the tire, the rotating roller 533 reduces the friction of the tire.
[0043] Step 2: While operating the tire, the rim front rim centering station ensures that the rim is in the center and the rim air nozzle is in the front. After the centering, the rim of the wheel is on the movable plate 6. The propulsion cylinder propels the movable plate 6 and the centered rim along the slide rail to the assembly station. At this time, the electric control cabinet receives a signal, and the ejection cylinder, i.e., the lower cylinder 522, pushes the rim bracket 525 out. When passing the movable plate 6, it rises with the upper rim. When it rises to the lower position of the ejection cylinder, the electric control cabinet receives a signal and lets the propulsion cylinder retract with the movable plate 6 to transport the next rim.
[0044] Step 3: While the lower cylinder 522 is rising to the top cylinder lower position, the electric control cabinet controls the tilt cylinder 54 to retract. Normally, the tilt cylinder 54 is in an extended state. When the tilt cylinder 54 is retracted to the tilt cylinder lower position, the rim air valve opening on the rim bracket 525 leaks out. Manually insert the tire valve into the rim air valve opening.
[0045] Step 5: Manually press the next button again. After the electric control cabinet receives the next button signal again, it controls the ejection cylinder, i.e., the lower cylinder 522, to drive the rim bracket 525, the rim, and the tire to continue to extend to the upper position of the ejection cylinder. Then, the support cylinder 5341 is controlled to extend. At this time, the support cylinder 5341 drives the slider 5343 to the lower end of the rim. After the support cylinder 5341 extends for 10 seconds, the lower cylinder 522 drives the rim bracket 525 to retract to the initial position. At the same time, the assembled tire rim is manually sent to the next workstation. After all operations are completed, press the finish button, the support cylinder 5341 retracts, and the next cycle starts.
[0046] Example 2:
[0047] Specifically, if Figures 1 to 8 As shown, the automatic centering and selection mechanism 4 includes a support frame 41, a lifting assembly 42 fixedly installed at the center of the support frame 41 through a transverse plate, a rotating assembly 43 installed on the top of the lifting assembly 42, positioning assemblies 44 symmetrically arranged on both sides of the rim transfer line 3, and a driving assembly 45 for synchronously driving the two groups of positioning assemblies 44 to work.
[0048] The lifting assembly 42 comprises a base 421 fixedly installed at the center of the support frame 41, a lifting cylinder 422 arranged through the base 421, a lifting plate 423 connected with the output rod of the lifting cylinder 422, and two groups of guide rods 424 arranged through the lifting plate 423 and the base 421 in sequence.
[0049] It should be noted that the guide rods 424 can ensure the stability and accuracy of the lifting plate 423 during lifting. When the lifting cylinder 422 works, the lifting plate 423 connected with the output rod of the lifting cylinder 422 will rise, and in this process, the two groups of guide rods 424 will also rise with the lifting plate 423, thereby ensuring the stability and accuracy of the lifting plate 423 during lifting.
[0050] The rotating assembly 43 comprises a bearing frame 431 installed on the lifting plate 423, a rotating motor 432 installed inside the bearing frame 431, a stabilizing frame 433 installed on the top of the bearing frame 431, a connecting shaft 434 connected with the output shaft of the rotating motor 432 and arranged through the bearing frame 4331 and the stabilizing frame 433 in sequence, and an alignment tray 435 connected with the top end of the connecting shaft 434.
[0051] It should be noted that when the lifting cylinder 422 works, the rotating motor 432 also works, and the alignment tray 435 is driven to rotate by the connecting shaft 433, that is, the rim is rotated, so as to detect the length of the rim air nozzle and other parameters.
[0052] The positioning assembly 44 comprises a gear box 441 installed on one side of the rim transfer line 3, a drive gear 442 and a driven gear 443 arranged inside the gear box 441, and two groups of clamping units 444 connected with the drive gear 442 and the driven gear 443, respectively.
[0053] The clamping unit 444 comprises a long shaft 4441, a clamping arm 4442 fixedly connected to the top end of the long shaft 4441, and a clamping wheel 4443 rotationally connected to the clamping arm 4442 through a fixed shaft. The two groups of long shafts 4441 are arranged through the gear box 441 and are fixedly connected with the centers of the drive gear 442 and the driven gear 443, respectively.
[0054] The driving assembly 45 comprises a cylinder seat 451 installed on one side of the rim transfer line 3, a clamping cylinder 452 arranged in a hinged manner with the cylinder seat 451, a connecting rod unit 453 hingedly connected with the output end of the clamping cylinder 452, and two groups of short shafts 454 connected with the drive gear 52.
[0055] The connecting rod unit 453 comprises a bent rod 4531 hingedly connected with the output end of the clamping cylinder 452, a straight rod 4532 hingedly connected with the bent rod 4531, and a trapezoidal rod 4533 hingedly connected with the straight rod 4532, and the bent rod 4531 and the top part of the trapezoidal rod 4533 are respectively connected with the bottom of the two groups of short shafts 454.
[0056] It should be noted that the automatic centering selection mechanism is provided with a detection sensor, a load sensor, an air nozzle detection sensor and a PLC register.
[0057] Specific working mode:
[0058] Step S1, first, the rim is positioned, and the rim is transported on the rim transfer line 3. When transported to the specified position, the control cabinet automatically starts the clamping cylinder 452 to push the connecting rod unit 453 to move, so as to drive the driving gear 442 to rotate through the two groups of short shafts 454, that is, drive the passive gear 443 engaged with it to rotate, so as to make the two groups of clamping units 444 rotate inward at the same time, thereby clamping the rim;
[0059] Step S2, detecting the diameter of the rim, after contact, the detection sensor confirms the position signal, and feeds back to the PLC of the control cabinet, so as to deduce the extension length of the clamping cylinder to determine the diameter of the rim;
[0060] Step S3, detecting the weight of the rim, the voltage analog signal of the load sensor is fed back to the PLC of the control cabinet, and the PLC converts the analog signal into a weight value;
[0061] Step S4, detecting the length of the rim air nozzle, after the above detection is completed, the lifting cylinder 422 is started to drive the rotary motor 432 and the rim to lift and separate from the rim transfer line, and the rotary motor 432 is started to drive the rim to rotate, and the air nozzle detection sensor detects the position of the rim air nozzle. When detected, the detection forms a pulse signal feedback to the PLC of the control cabinet, and the PLC determines the length of the air nozzle according to the range of the pulse signal;
[0062] Step S5, rim sorting, through the results of the above detection, the rim model is determined by comparing with the database of the PLC, and the model data is stored in the PLC register, at the same time, the rotary motor 432 stops rotating, the lifting cylinder 422 retracts, and the rim returns to the rim transfer line 3, and then is transported to the automatic sorting line. In the sorting process, the rim is sorted to the corresponding production line according to the rim model.
[0063] Specifically, after the rim is clamped and positioned, the detection sensor immediately starts to work, acquires the position signal after the rim contacts the clamping unit, and rapidly feeds back the signal to the PLC of the control cabinet; the PLC reverses the extension length of the clamping cylinder according to the preset algorithm, the position signal fed back by the detection sensor, and the related parameters of the clamping cylinder, so as to accurately determine the diameter of the rim; at the same time, the weight sensor continuously detects the weight of the rim and transmits the detected voltage analog signal to the PLC of the control cabinet; the analog-digital conversion module in the PLC converts the analog signal into a digital weight value, which is one of the important bases for determining the rim model; after the diameter and weight detection are completed, the lifting cylinder drives the rotary motor and the rim to lift and separate from the rim transfer line, and the rotary motor is started to drive the rim to rotate; the air nozzle detection sensor monitors the position of the air nozzle in real time during the rotation of the rim; when the air nozzle is detected, the air nozzle detection sensor generates a pulse signal and feeds it back to the PLC of the control cabinet; the PLC accurately determines the length of the air nozzle according to the range of the pulse signal and the preset algorithm; finally, the PLC compares the detected diameter, weight and length of the air nozzle with the four rim models A, B, C and D in the PLC database one by one; through accurate data analysis and logical judgment, the PLC determines the rim model and stores the model data in the PLC register; then, the rotary motor stops rotating, the lifting cylinder retracts, and the rim returns to the rim transfer line; the rim transfer line transports the rim to the automatic sorting line, and in the sorting process, the system accurately sorts the rim to the corresponding production line according to the rim model, completing the entire rim classification process.
[0064] The database of the PLC includes the following four rim models:
[0065] A: the diameter is set to 390-410mm, the weight is set to 13.8-14.1KG, and the air nozzle length is set to 45-48mm;
[0066] B: the diameter is set to 390-410mm, the weight is set to 15.5-16.5KG, and the air nozzle length is set to 45-48mm;
[0067] C: the diameter is set to 500-520mm, the weight is set to 40-42KG, and the air nozzle length is set to 53-55mm;
[0068] D: the diameter is set to 500-520mm, the weight is set to 44-46KG, and the air nozzle length is set to 50-53mm.
[0069] The application is described above with reference to the drawings; obviously, the specific implementation of the application is not limited to the above-described manner, and various non-essential improvements can be made to the application using the method concept and technical solutions of the application; or the above-mentioned concept and technical solutions of the application are directly applied to other occasions without improvement, and all fall within the protection scope of the application.
