The present invention relates to a method for manufacturing a display device and a display device according to the method, the method comprising the following steps: placing a plurality of light-emitting elements on a first transfer film; stretching the first transfer film so that the plurality of light-emitting elements are spaced apart from each other; transferring the plurality of light-emitting elements onto a TFT array substrate; and removing the transfer film from the plurality of light-emitting elements.

The utility model relates to a novel high -pressure safety explosion -proof film -coated capacitor shell, its characterized in that: the shell includes aluminium base layer, film layer, the shell inside is provided with the cavity for accommodating nucleon, the cavity one end is provided with the opening, the aluminium base layer outer peripheral surface covers film layer, film layer and aluminium base layer outer peripheral surface are combined integrally and form the shell. Through adopting a kind of to melt liquid state coating hot-pressing formation in aluminium base layer obtains novel high -pressure safety explosion -proof film -coated shell, solves the technical bottleneck of the existing solid-state film pasting process, can obviously improve the peel strength between film layer and aluminium base layer, solves the problem that film layer appears to fall off or bulge on the surface of aluminium shell in processing or high temperature environment, reduces process yield. It can be applied to the high -voltage aluminium electrolytic capacitor of voltage greater than 400V, is applicable to AI server, electric automobile, photovoltaic energy storage, communication equipment, artificial intelligence and other national strategic emerging industries have extensive market demand.

The application relates to a heat exchanger, comprising a heat exchange unit and a connecting unit, the number of the heat exchange units is at least two, each heat exchange unit comprises a header section arranged along a first direction, and the plurality of header sections are coaxially and sequentially arranged at intervals; at least part of the connecting units is arranged between two adjacent header sections along the first direction, and the two ends of the connecting unit are respectively communicated with the corresponding side header sections. The application connects the header sections in the adjacent heat exchange units by using the connecting unit, so that a plurality of shorter header sections can form a longer header section. Compared with the heat exchanger without the connecting unit, the plurality of header sections in the heat exchanger of the application are shorter, therefore, each shorter header section is not prone to bending deformation during production, and the plurality of shorter header sections can reduce the processing difficulty and the product processing failure rate when the heat exchanger is manufactured.

The utility model relates to a riveting operation counting device which comprises a riveting gun and a control box, a switching power supply and a magnetic force type water flow switch are arranged in the control box, the magnetic force type water flow switch is connected with an air source through an air inlet connector and connected with the riveting gun through an air outlet connector, and the magnetic force type water flow switch is electrically connected with a time relay and a counter. The magnetic water flow switch, the time relay and the counter are powered by a switching power supply, and the counter is provided with a work indicating lamp, a buzzer and a reset button. The automatic riveting machine is simple in structure and convenient to operate, the pneumatic sensing element is matched with the timer to count riveting operation, the machining reject ratio of the lower shell of the aluminum battery tray is reduced, and riveting missing accidents caused by negligence of manual operation are avoided; the workload of quality inspection and acceptance related personnel is greatly reduced, and the labor cost is saved.

The utility model discloses a kind of aligning tool for supercharger nozzle ring machining, the utility model relates to the technical field of machining. Including nozzle ring, the outer wall of the nozzle ring is fixedly connected with vane, further include: aligning component, the side of aligning component close to vane is slidably connected with adjusting assembly, the adjusting assembly includes protective cover, the inside rotationally connected with gear of protective cover, the upper and lower of gear are all meshingly connected with rack bar;By rotating handle, aligning block can be driven to move flexibly, without replacing whole tooling, only simple adjustment can adapt to the processing needs of different outer diameter, different vane distribution density, reduce tooling change time and inventory cost, on the convenience of operation, aligning process step is clear, operator can complete adjustment by pulling locking rod, rotating handle, quickly confirm in combination with pointer and scale, after processing, reverse operation can reset tooling, replace repeatedly trial processing workpiece, shorten single-piece aligning time-consuming.

This utility model discloses a tooling for processing the top cover of a spinning assembly, relating to the field of processing tooling. It includes: a clamping and positioning seat for assembling the top cover; a positioning device symmetrically mounted on the clamping and positioning seat for positioning the top cover; and an indexing chuck that cooperates with the clamping and positioning seat and is used to adjust the angle of the clamping and positioning seat. This tooling for processing the top cover of a spinning assembly allows for rapid positioning of the workpiece by inserting the top cover into the clamping and positioning seat, positioning the top cover by the positioning device, and rotating it to the required angle using the indexing chuck. This enables the machining of oblique holes and countersunk holes in a machining center. The oblique holes produced by this tooling have stable angles, improving processing efficiency and significantly reducing the defect rate caused by inaccurate clamping and positioning. Through the synergistic effect of the clamping and positioning seat and the positioning device, rapid and accurate positioning of the workpiece is achieved.
