The invention relates to a touch display device which comprises a display module, a touch module and an elastic optical film, wherein the touch module is configured above the display module; the elastic optical film has no viscosity and is positioned between the touch module and the display module; and when the touch module is assembled above the display module, the elastic optical film generateselastic deformation to absorb a clearance of a surface between the touch module and the display module.

The invention discloses an engine timing chain system assembly tool and an assembly method. The assembly tool comprises a crank timing tool, a cam shaft timing tool and a tensioner tool. Through the adoption of the assembly tool provided by the invention, the assembly positioning accuracy can be effectively improved.

This invention discloses a folded polar plate lead acid battery and its making method, among which the lead wire connecting two plates is folded into u-shape and monopolar and bipolar plates are arranged in the box in sequence according to the matched polarities, a V-shaped diaphragm wraps both sides of each plate, insulation bag sleeve two adjacent polar plates and the diaphragm warapping the polar plates, realizing internal serials connection by lead wires. The lead acid battery has the advantages of small volume, light weight and good power characteristic.

The invention relates to a part surface design method capable of improving automatic assembling visual identity. The part surface design method comprises the following steps of step I, arranging a reference characteristic on the surface of a part, wherein the reference characteristic is located at the middle part of the surface of the part, the reference characteristic at least comprises one continuous edge, and the continuous edge is a curve; and step II, locally performing gold-plating treatment or metal oxidation treatment on the surface of the part on a region except the reference characteristic on the surface of the part, and enabling the other part of the surface of the part to maintain the primary color of the part. Through the adoption of the method disclosed by the invention, therecognition degree of the visual identity of the part surfaces is high, and the clarity of a visual sense template is higher, so that the automatic deviation correcting capacity of an assembling robotis improved, the surface treatment manner having color differences is easy to realize, and development cost cannot be increased.

The method of installing the magnet in the round hole includes the following installation steps: install the yoke body into the fixture base, install the auxiliary magnet with the auxiliary magnet installation jig and push the auxiliary magnet jig, and install the magnet positioning block into the In the yoke body, put the simulated magnetic steel into the yoke body, replace the first simulated magnetic steel with the first magnetic steel and press it with the pressure plate structure, and replace the one next to the first magnetic steel with the second magnetic steel For the second piece of simulated magnet, push the second piece of magnet close to the first piece of magnet by rotating the pressing device, and press it tightly with the pressure plate structure; install the remaining magnet according to the replacement method of the second piece of magnet above; Fasten the yoke body and the magnetic steel positioning block with the fastening magnetic steel device, then take it out from the fixture base and perform position curing to complete the installation. The invention adopts a special assembly fixture and installs the magnetic steel with a specific process method, can well control the assembly process of the magnetic steel, meets the assembly requirements of the magnetic steel, has high positioning accuracy, simple and practical assembly process, and can be installed in place at one time, reducing Assembly rework rate.
