Description

Technical Field

[0001] The invention relates to the field of walking belt manufacturing, and in particular to a method for manufacturing a walking belt for a window cleaning robot and a product thereof. Background Art

[0002] The walking belt of the window cleaning robot is to help the robot maintain smooth movement on the window according to the set program to achieve glass cleaning.

[0003] The walking belt connects the motor and the cleaning module of the window cleaning robot, and effectively transmits the power of the motor to the cleaning module.

[0004] The walking belt of the window cleaning robot usually consists of three parts: the main body of rubber (inner rubber, outer rubber), the skeleton material cord and the covering cloth layer (see Figure 1 ).

[0005] At present, the preparation process of the walking belt for window cleaning robots is complicated and the cost is high, which has been a problem for the industry. The existing industry adopts casting or injection processing technology, such as Chinese patent CN2020114174841 "A synchronous belt for window cleaning robots and its preparation method", Chinese patent CN201510793610.6 "A synchronous belt for window cleaning robots", Chinese patent CN105504564B "A synchronous belt for window cleaning robots and its manufacturing method", Chinese patent CN202022961124.X "A synchronous belt for glass cleaning robots", Chinese patent CN204971089U "A synchronous belt for glass cleaning robots", and Chinese patent CN216984714U "A belt and window cleaning robot". The manufacturing method of the product is usually cast or injected.

[0006] The manufacturing method of casting or injection molding products generally includes the following steps:

[0007] a. Heat the prepolymer to about 85℃, and vacuum degas for about 45 minutes while stirring;

[0008] b. Wind the wire on the inner rubber molding mold through a winding machine;

[0009] c. Put the inner glue forming mold into the drying oven and adjust the temperature to about 120℃ for more than half an hour;

[0010] d. Pour the prepolymer into the preheated mold and wait for a few minutes to solidify;

[0011] e. Put it in the oven and cook it at a constant temperature of about 120℃ for about 1 hour before removing from the mold to complete the first cooking;

[0012] f. Put the semi-finished product that has been matured once into an oven, raise the temperature to about 85°C, and then mature it for about 4 hours to complete the inner side glue molding;

[0013] g. Then put the inner plastic molded part into the outer plastic mold, and repeat steps a to obtain the finished product. However, the traditional method of manufacturing cast molded products has the following shortcomings:

[0014] 1. The processing technology is complicated. Not only the inner and outer glues are processed in two steps, but also one product is obtained in one mold, which has low production efficiency and high cost.

[0015] 2. The product is prone to bubbles and shortages, and the yield rate is low, about 90%.

[0016] 3. The product has low density and poor wear resistance.

[0017] 4. High labor intensity and high energy consumption.

[0018] Therefore, in order to improve the existing process and enhance production efficiency, the present invention provides a method for manufacturing a walking belt for a window cleaning robot. Summary of the invention

[0019] In order to overcome the above-mentioned defects of the prior art, the purpose of the present invention is to overcome the shortcomings of the traditional casting molding product preparation method of the walking belt, and to provide a manufacturing method that does not use casting molding. This method improves production efficiency and yield rate by using the advanced process of encapsulation vulcanization.

[0030] The fifth step is to grind the semi-finished belt sleeve to the required size, and then groove, grind and cut the surface to obtain the walking belt product for the window cleaning robot.

[0031] In a preferred embodiment of the present invention, the rope is made of glass fiber.

[0032] In a preferred embodiment of the present invention, the vulcanization reaction is to first open the steam external pressure for vulcanization for 3-10 minutes, so that the bladder is compressed and contracted to ensure sufficient flow of the rubber material, and then open the steam internal pressure for heating and vulcanization until the vulcanization is completed.

[0033] In a preferred embodiment of the present invention, the grinding to the required size is to put the semi-finished belt tube on the grinding machine drum, start the grinder and the vacuum cleaner, and after the grinder runs balanced, slowly enter the grinding wheel and grind to the required size.

[0034] In a preferred embodiment of the present invention, the surface grooving is performed by putting the semi-finished belt drum on a grooving machine, and uniformly making drainage grooves on the surface of the semi-finished belt drum, with a groove width of 0.3-1 mm and a groove depth of 0.3-1 mm.

[0035] In a preferred embodiment of the present invention, the edge grinding and slitting are to place the semi-finished belt roll into an edge grinding and slitting machine, and after balanced operation, enter edge grinding and slitting, the edge grinding angle is 45-60 degrees, and the slitting width is as required, so as to obtain the walking belt for the window cleaning robot.

[0036] A walking belt for a window-cleaning robot is prepared by the above method.

[0037] The beneficial effects of the present invention are:

[0038] Compared with the prior art, the present invention is a manufacturing method that does not use casting molding.

[0045] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the scope of the present invention. In addition, in the following structure, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the present invention.

[0046] Compared with the prior art, the technical features of the present invention are further manifested as follows:

[0047] In the prior art, the manufacturing method of casting or injection molding products usually adopts a two-step method to include inner and outer glue, that is, firstly cast the inner glue and then cast the outer glue after curing, which is complex and inefficient. In the present invention, the inner glue, outer glue and vulcanization are realized in a one-step method, which simplifies the processing technology and improves the production efficiency.

[0048] The existing technology usually uses casting or injection molding under normal pressure, which is easy to produce bubbles, lack of materials and low quality rate.

[0049] The present invention realizes pressure control by utilizing the contraction and expansion of the capsule through airbag vulcanization, which can ensure uniform pressure distribution during the vulcanization process and is beneficial to improving product quality. Under the action of the external steam pressure of 12-18MPa, the rubber material flows fully with full teeth, the product is not prone to bubbles and material shortage, and the genuine product rate can reach more than 99.5%.

[0050] The prior art generally uses casting or injection molding to produce products that are vulcanized under normal pressure, resulting in low product density and poor wear resistance. The capsule vulcanization used in the present invention is performed under the action of an external steam pressure of 12-18 MPa, resulting in a product with high density and good wear resistance.

[0051] In the prior art, the manufacturing method of casting or injection molding products usually has a large change in product shrinkage due to the influence of processing parameters.

[0052] The capsule vulcanization manufacturing method adopted by the present invention can achieve high dimensional accuracy of the product after being polished by a grinder.

[0053] The prior art generally uses a casting or injection molding method to manufacture products, where one product is obtained from one mold, and the production efficiency is low.

[0054] The capsule vulcanization manufacturing method adopted by the present invention can cut and obtain 50 products by processing one mold, thereby significantly improving the production efficiency and greatly reducing the cost by multiples.

[0055] The prior art generally uses a two-step process for casting or injection molding products, which consumes a lot of energy. The capsule vulcanization used in the present invention uses a one-step process, which significantly reduces energy consumption.
