Description

Technical Field

[0001] The utility model relates to the technical field of tire handling, in particular to a tire vulcanization production line and a tire handling robot thereof. Background Art

[0002] In the current tire production process, especially in the vulcanization and subsequent processing stages from green tires to finished tires, there are a series of technical problems that need to be solved urgently. These problems not only affect production efficiency, but also seriously threaten the health and work safety of operators.

[0003] First, in traditional workshops, loading green tires from the green tire rack to the curing press is entirely manual. This manual loading method is not only inefficient but also increases worker intensity, leading to fatigue and the risk of work-related injuries over time.

[0004] Secondly, the temperature of the finished tire after vulcanization in the vulcanizer is high. In this high temperature environment, the rubber material will release irritating odors, which pose a serious threat to the respiratory system of the operators. Long-term exposure may cause occupational diseases, such as respiratory diseases, which seriously damage the health of the workers.

[0005] Furthermore, the process of transporting finished tires from the vulcanizer to the PI machine (forming machine) also relies on manual labor, which is time-consuming and inefficient. Furthermore, working in a high-temperature environment (40-50°C) exacerbates worker fatigue. This is especially true in the summer, when high-temperature working environments can easily lead to heatstroke, fainting, and even more serious health problems such as heat stroke, seriously threatening workers' lives.

[0006] Furthermore, after the PI machine completes the shaping process, the finished tires must be manually hung on the hanging chains. This process is also inefficient and prone to errors. Due to the wide variety of products in the workshop, each product requires a different specification of hanging chain hook. Manual operation is prone to errors, leading to chaotic production processes and affecting product quality and production efficiency.

[0007] Finally, the vulcanizer needs to regularly replace tire molds during the production process. This task is usually completed by a motorized forklift. Although mechanized operation has been achieved, the frequency of mold replacement and the requirements for precision throughout the entire production process still place high demands on production efficiency and equipment maintenance.

[0008] In view of this, the applicant filed this application after studying the existing technology. Utility Model Content

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] Example 1: Figures 1 to 7 As shown, an embodiment of the present invention provides a tire handling robot 20 for a tire curing production line, comprising a base assembly 1, a robotic arm assembly 2 coupled to the base, and a tire attachment assembly 3 coupled to the robotic arm assembly 2. The robotic arm assembly 2 is used to move the tire attachment assembly 3. The first driving member 12 is used to drive the rotating guide plate 13 to rotate.

[0041] The tire attachment assembly 3 includes a support base 8 for engaging with the robotic arm assembly 2, a plurality of attachment movable parts 14 circumferentially distributed on the support base 8, a rotating guide plate 13 engaged with the attachment movable part 14, and a first driving part 12 transmission-connected to the rotating guide plate 13.

Specifically, the second tire attachment part 18 with an arc structure can better fit on the tire. Preferably, the number of the attachment movable parts 14 is four. The four attachment movable parts 14 are centrally symmetrically arranged with the support base 8.

[0042] The rotating guide plate 13 is provided with a guide groove 11 adapted to the guide portion 15. The guide groove 11 is configured to move the guide portions 15 of the plurality of attached movable members 14 closer to or further away from each other when the rotating guide plate 13 rotates. Preferably, the guide groove 11 is configured as an arc-shaped through-hole structure.

[0043] The tire handling robot 20 for a tire vulcanization production line according to the present invention significantly improves production efficiency and optimizes space utilization. Compared to traditional truss module and robotic arm combinations, this technology can fully utilize existing limited space, achieve comprehensive spatial coverage, and effectively save production time.

[0044] On the basis of the above embodiments, in an optional embodiment of the present invention, as Figures 1 to 4 As shown, the tire handling robot 20 further includes a moving assembly 4 coupled to the robotic arm assembly 2. The tire handling robot 20 includes at least two tire attachment assemblies 3. The at least two tire attachment assemblies 3 are slidably coupled to the moving assembly 4. The moving assembly 4 is configured to adjust the distance between the tire attachment assemblies 3.

[0045] The moving assembly 4 includes a bracket 5 coupled to the robotic arm assembly 2, and at least two second driving members 6 coupled to the bracket 5. The support base 8 is slidably coupled to the bracket 5. The second driving members 6 are transmission-connected to the support base 8 and are configured to drive the support base 8 to move on the bracket 5.

[0046] Specifically, by adjusting the distance between the tire attachment assemblies 3 using the movable assembly 4, the tire handling robot 20 can simultaneously accommodate tires of varying sizes, the green tire rack 19, the vulcanizer 21, and the PI shaping machine 22, significantly improving the versatility of the tire handling robot 20. In other embodiments, only one tire attachment assembly 3 may be installed without the movable assembly 4, and this is not specifically limited in the present invention.

[0047] On the basis of the above embodiments, in an optional embodiment of the present invention, as Figures 4 to 7 As shown, the support seat 8 is provided with an annular support portion 9, and a connecting portion 10 extending outward from the annular support portion 9. The multiple attachment movable parts 14 are distributed circumferentially on the annular support portion 9.
