And the initial shape after expansion is not influenced.

The utility model belongs to the field of chip heat curing, specifically disclose a kind of general heat-pressing curing fixture of multi-size LCoS chip, including bottom plate, detachably connected on the cover plate of bottom plate and be used for pressing chip air bag, bottom plate, cover plate between the installation space for chip installation formed, cover plate detachably connected with pressure bar, pressure bar is used to in the circumferential direction of air bag to air bag perimeter is fixed;Bottom plate detachably connected with several pressing blocks, pressing block is arranged in the inside of pressure bar, and the upper and lower ends of pressing block are respectively and cover plate, bottom plate are in abutment, and multiple pressing blocks are used to be in the circumferential direction of air bag and the expansion range of air bag is positioned.Using the scheme of the utility model, it can solve the problem that the fixture in the prior art is only suitable for a specific size of chip, and when the production line needs to switch to produce chips of different sizes, the fixture needs to be replaced, reducing the production efficiency.

The invention discloses angle valve assembling equipment, and relates to the technical field of valve assembling, the angle valve assembling equipment comprises a tightening device, the tightening device is used for tightening angle valve parts to complete assembling of an angle valve, the tightening device is composed of a first sliding assembly and a cross-shaped tightening head, and the angle valve assembling equipment is characterized by further comprising a water pressure detection mechanism; the water pressure detection mechanism is used for testing the sealing performance of the finished product angle valve, the water pressure detection mechanism is composed of a sealing ring, a water pressure pipe, a guide rail, a piston, a groove, a firing pin, a water pressure cover, a firing pin pipe and a second sliding assembly, and the sliding rail lifting mechanism is used for adjusting the vertical height of the tightening device. The sliding rail lifting mechanism is composed of a sliding rail lifter, a sliding frame, a sliding beam, a transverse sliding rail and a longitudinal sliding rail, and the mechanical arm clamping mechanism is used for clamping a finished angle valve. Full-automatic operation can be achieved in the angle valve assembling process, sealing detection is automatically conducted after assembling is completed, and therefore the labor intensity of workers is greatly reduced.

This invention provides an adaptive pressure head structure for welding cylindrical modules, comprising a lower mounting component, a ceramic pressure head, an elastic element, and an upper mounting component mounted on a laser welding equipment. The lower mounting component is fixedly connected to the upper mounting component. Both the upper mounting component and the ceramic pressure head are provided with laser channels for laser transmission. The lower mounting component has a mounting groove, and the ceramic pressure head is buoyantly housed within the mounting groove of the lower mounting component. The bottom of the mounting groove has an opening, and the laser channel exit end of the ceramic pressure head extends out of the opening. One end of the elastic element abuts against the upper mounting component, and the other end of the elastic element abuts against the ceramic pressure head. This invention also provides a laser welding equipment including the aforementioned adaptive pressure head structure for welding cylindrical modules.

The utility model relates to the field of electrolytic baths, and discloses a PEM electrolytic bath and a hydrogen compressor, and the PEM electrolytic bath comprises a hydrogen channel which is arranged on the center line of the electrolytic bath and is used for leading out generated hydrogen; the water channel and the oxygen channel are symmetrically arranged on the two sides of the hydrogen channel, the water channel is located above the oxygen channel, the water channel is used for conveying water, and the oxygen channel is used for guiding out generated oxygen; the hydrogen channel, the waterway channel and the oxygen channel are positioned on the same central axis; the hydrogen channel is communicated with one end of the electrolytic cell, and the waterway channel and the oxygen channel are both communicated with the other end of the electrolytic cell.
