Description

Technical Field

[0001] This utility model relates to the field of tire production equipment, specifically to a lubricating oil filling system for a tire loading and unloading robot in a vulcanizing machine. Background Technology

[0002] Currently, with the rapid development of China's automotive industry, the demand for tires is increasing. Tire production generally involves the following steps: raw material preparation – rubber refining and compounding – tread and carcass manufacturing – semi-finished product production – molding – vulcanization – quality inspection and packaging.

[0003] After assembling semi-finished products such as the tread, carcass, and cord fabric into a green tire (an uncured tire, also called a tire blank) on a forming machine, the formed green tire needs to be placed in a vulcanizing machine for vulcanization under appropriate time and conditions in a mold. After vulcanization, the upper vulcanization chamber mold (i.e., the upper mold cavity) is lifted by a gantry crane, and then the tire is transported to the next process by a tire loading and unloading robot.

[0004] The tire loading and unloading robot used in this factory has numerous moving parts, including sixteen key moving structures such as the inner bearings of the left and right crank gears, the left and right bearings of the worm gear shaft, the inner bearings of the left and right intermediate shafts, the left and right gear pairs of the worm gear shaft, the outer bearings of the left and right crank gears, the left and right crank gear pairs, the outer auxiliary bearings of the left and right intermediate shafts, the guide rod bearings of the tire unloading mechanism, the piston rod bearings of the tire unloading mechanism, the lifting device bearings, the end washers of the left and right connecting rods and the upper crossbeam, the guide wheels of the left and right small tie rods, the guide wheels of the left and right journals of the upper crossbeam, the upper bearings of the left and right connecting rods, the lower bearings of the left and right connecting rods, and the rotation in and rotation out bearings. These components play a crucial role in the daily operation of the robot, and to ensure smooth operation and reduce wear, these moving parts must be lubricated regularly.

[0005] However, this robotic arm is not equipped with an automatic lubrication system. Therefore, workers must manually lubricate the various moving parts using a lubricant can at regular intervals. For lower-positioned moving parts, this process is relatively simple, and workers can operate it directly. The problem lies in the fact that some moving parts of the robotic arm are located at higher positions. In these cases, workers must use ladders to climb and reach them to apply lubricant. This method is not only time-consuming and labor-intensive, significantly increasing the worker's workload, but also poses a serious safety hazard when using ladders for high-altitude work, as the ladders may become unstable and tip over. Utility Model Content

Its purpose is to improve the existing tire loading and unloading robot in the factory and solve the problem that the existing robot does not have an autonomous lubricating oil filling system, so as to save manpower and avoid safety risks.

[0014] Furthermore, the grease dispenser A is connected via pipelines to the inner bearing grease ports of the left and right crank gears, the left and right bearing grease ports of the worm gear shaft, and the inner bearing grease ports of the left and right intermediate shafts, respectively; the grease dispenser F is connected via pipelines to the inner bearing grease ports of the left and right crank gears, the left and right bearing grease ports of the worm gear shaft, and the inner bearing grease ports of the left and right intermediate shafts, respectively; the grease dispenser B is connected via pipelines to the auxiliary bearing grease ports of the left and right worm gears, the outer bearing grease ports of the left and right crank gears, the auxiliary bearing grease ports of the left and right crank gears, and the outer auxiliary bearing grease ports of the left and right intermediate shafts, respectively; the grease dispenser E is connected via pipelines to the auxiliary bearing grease ports of the left and right worm gears, the outer bearing grease ports of the left and right crank gears, and the inner bearing grease ports of the left and right intermediate shafts, respectively. The gear assembly filler port is connected to the filler port of the outer auxiliary bearing of the left and right intermediate shafts; the dry oil distributor C is connected to the filler port of the guide rod bearing of the tire unloading mechanism and the filler port of the piston rod bearing of the tire unloading mechanism through pipelines respectively; the dry oil distributor D is connected to the filler port of the guide rod bearing of the tire unloading mechanism and the filler port of the piston rod bearing of the tire unloading mechanism through pipelines respectively; the dry oil distributor G is connected to the filler ports of the inner bearings of the left and right crank gears, the outer bearings of the left and right crank gears, the filler port of the lifting device bearing, and the filler port of the swivel-in and swivel-out bearings through pipelines respectively; the dry oil distributor H is connected to the filler ports of the inner bearings of the left and right crank gears, the outer bearings of the left and right crank gears, and the filler port of the lifting device bearing through pipelines respectively.

[0015] Furthermore, the dry oil distributor I is connected to the oil filling port of the upper crossbeam end face washer and the oil filling port of the left and right small tie rod guide wheels through pipelines and left and right connecting rods respectively.

[0019] The beneficial effects achieved by this utility model are as follows:

[0020] First, by setting up a dry oil pump and several dry oil distributors, and arranging them around the robot arm, automatic distribution and filling of lubricating oil is achieved. This design ensures that each moving part of the robot arm receives lubricating oil regularly and quantitatively, effectively avoiding damage to the robot arm caused by workers forgetting to add lubricating oil, thereby extending the robot arm's service life and improving its operational stability.

[0021] Secondly, this invention automates the lubrication process, significantly reducing labor costs. Traditionally, workers manually add lubricating oil to the various moving parts of the robotic arm, which is time-consuming, labor-intensive, and prone to errors. This invention, through an automatic control system, enables the dry oil pump to automatically activate at regular intervals, pumping lubricating oil from the tank into each dry oil distributor. After precise flow control, the oil is then added to each moving part. The entire process requires no manual intervention, greatly reducing the labor intensity of workers; it also avoids waste and reduces the amount of lubricating oil used.

[0022] Furthermore, automated operation brings significant safety benefits. Since workers no longer need to frequently climb the robotic arm for lubrication, the safety risks associated with climbing are eliminated, ensuring worker safety. This not only meets the safety requirements of modern enterprises but also helps improve the overall safety management level of the company.

[0023] In summary, this utility model, by achieving automatic lubrication of the robotic arm, not only extends the service life of the equipment and improves operational stability, but also saves labor costs, reduces maintenance difficulty, and significantly enhances operational safety.

[0038] Among them, the starting end of the main refueling pipe 40, the first refueling pipe branch 41 and the second refueling pipe branch 42 are the ends where lubricating oil enters, and the other end is the end.

[0040] The dry oil distributors A301, B302, C303, D304, E305, F306, G307, H308, I309, J310, K311, L312, M313, and N314 are arranged around the tire loading and unloading robot. They can be installed on the robot or on equipment around it. The aim is to ensure that each dry oil distributor is close to its assigned filling port without affecting the operation of the robot. The specific arrangement depends on the actual site conditions and can be easily implemented by those skilled in the art, so the arrangement details will not be described in detail.

[0041] The dry oil distributors A301, B302, C303, D304, E305, F306, G307, H308, I309, J310, K311, L312, M313, and N314 are all connected to different oil filling ports on the robotic arm through several pipelines.

[0042] The various pipes used in this utility model can be flexible or rigid pipes, and the arrangement depends on the requirements, which will not be elaborated in detail in this article.

[0043] Specifically, the dry oil distributor A301 is connected to the inner bearing filler ports 1 of the left and right crank gears, the left and right bearing filler ports 2 of the worm gear shaft, and the inner bearing filler ports 3 of the left and right intermediate shafts via pipelines; the dry oil distributor F306 is connected to the inner bearing filler ports 1 of the left and right crank gears, the left and right bearing filler ports 2 of the worm gear shaft, and the inner bearing filler ports 3 of the left and right intermediate shafts via pipelines. The dry oil distributor B302 is connected to the auxiliary bearing filler ports 4 of the left and right worm gears, the outer bearing filler ports 5 and 6 of the left and right crank gears, and the outer auxiliary bearing filler port 7 of the left and right intermediate shafts via pipelines; the dry oil distributor E305 is connected to the auxiliary bearing filler ports 4 of the left and right worm gears, the outer bearing filler ports 5 and 6 of the left and right crank gears, and the outer auxiliary bearing filler port 7 of the left and right intermediate shafts via pipelines. The dry oil distributor C303 is connected to the tire unloading mechanism guide rod bearing filler port 8 and the tire unloading mechanism piston rod bearing filler port 9 via pipelines. The dry oil distributor D304 is connected to the tire unloading mechanism guide rod bearing filler port 8 and the tire unloading mechanism piston rod bearing filler port 9 via pipelines. The dry oil distributor G307 is connected to the left and right crank gear inner bearing filler port 1, the left and right crank gear outer bearing filler port 5, the lifting device bearing filler port 10, and the rotary bearing filler port 16 via pipelines. The dry oil distributor H308 is connected to the left and right crank gear inner bearing filler port 1, the left and right crank gear outer bearing filler port 5, and the lifting device bearing filler port 10 via pipelines.

[0044] The dry oil distributor I309 is connected to the oil filling port 11 of the upper crossbeam end face washer and the oil filling port 12 of the left and right small pull rod guide wheels through pipelines and left and right connecting rods respectively.

[0045] The dry oil distributor J310 is connected to the oil filling ports 13 of the left and right journal guide wheels of the upper crossbeam and the oil filling ports 14 of the upper bearings of the left and right connecting rods through pipelines; the dry oil distributors K311 and N314 are both connected to the oil filling ports 15 of the lower bearings of the left and right connecting rods through pipelines; the dry oil distributor L312 is connected to the oil filling port 11 of the end face washer of the upper crossbeam and the oil filling ports 12 of the left and right small tie rod guide wheels through pipelines and the left and right connecting rods; the dry oil distributor M313 is connected to the oil filling ports 13 of the left and right journal guide wheels of the upper crossbeam and the oil filling ports 14 of the upper bearings of the left and right connecting rods through pipelines.

[0046] It is worth noting that, in order to ensure uniform lubrication and avoid wear on some moving parts due to uneven lubrication, each moving part of the robot arm may have more than one lubrication point; for example, the guide rod bearing of the tire unloading mechanism has four lubrication points, which are uniformly named "Tire Unloading Mechanism Guide Rod Bearing Lubrication Port 8" in this article; the situation is similar for other parts of the robot arm, and will not be repeated here; therefore, please refer to the following for the number and specific arrangement of lubrication points. Figure 2 and Figure 3Based on this, and with minor adjustments made according to the actual situation of the robotic arms in the workshop and the requirements of the production process; for those skilled in the art, no creative effort is required, so it will not be elaborated further.

[0047] Furthermore, the dry oil pump 20 is a pneumatic plunger type dry oil pump.

[0048] Furthermore, the dry oil distributor is model GF5-4, and its lubricating oil delivery rate can be manually adjusted.

[0049] Furthermore, the lubricating oil filling system also includes an alarm module (not shown in the figure). The alarm module includes a level detection module, a warning light, and an alarm bell installed inside the oil tank. The control module monitors the lubricating oil level in the tank through the level detection module. When the lubricating oil level in the tank falls below a warning value, the control module activates the warning light and alarm bell to remind workers to replenish the lubricating oil in time. The level detection module can be a traditional level sensor, an ultrasonic ranging sensor, or a float-type level sensor, etc. The specific type and model selected depends on the density and other characteristics of the lubricating oil.

[0050] Furthermore, the lubricating oil filling system also includes a control module (not shown in the figure). This control module is the central control unit of this application. It includes a PLC controller and several relays. The PLC controller operates the control system and controls the opening and closing of the dry oil pump 20, warning lights, and alarm bells via the relays. In addition, the PLC controller is connected to the control modules of the host computer and the robotic arm to facilitate control and linkage. For those skilled in the art, implementing the control module based on the description herein is relatively easy and requires no creative effort; therefore, specific details will not be elaborated further.

[0051] Specifically, the method of using this utility model is as follows: First, set the initial information such as the starting conditions, starting interval, and running time of the dry oil pump 20; second, the worker manually adjusts the lubricating oil output of each dry oil distributor according to experience, with the principle of adjusting the oil output gradually from large to small; then, start this utility model and use the robot normally, while checking whether there is any lubricating oil overflow at each point of the robot. If so, the worker needs to reduce the output of the corresponding dry oil distributor until there is no more lubricating oil overflow at each point; finally, this utility model can automatically run according to the settings to replenish and add lubricating oil to the robot.

[0052] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
