The utility model relates to an inductance type sensor fixed interval performance test frock. Including detection platform, the photoelectric sensor for inductance type sensor detection, the main shaft for driving photoelectric sensor rotation, the support seat for supporting main shaft, the drive arrangement for driving main shaft rotation, the mounting seat for supporting drive arrangement and the support frock for supporting inductance type sensor, support seat and mounting seat are installed at detection platform top respectively, drive arrangement is installed at mounting seat top end, main shaft is rotatably connected at support seat top end through bearing, drive arrangement is connected in one end of main shaft through shaft coupling drive. Solveed the prior art in the drive arrangement's rotating speed usually cannot high -speed rotation under no obvious vibration, lead to unable simulation sensor under high -speed rotation state real performance, the structure of test frock is fixed simultaneously, it is difficult to adapt to different models inductance type sensor, needs integral dismounting when replacing test object, the technical problem of low efficiency.

The invention relates to the technical field of semiconductor manufacturing, in particular to a photoresist smearing device for coating, which comprises a box body; the conveying assembly is used for conveying a substrate to be coated to a coating station and is arranged on the box body; the coating and cleaning integrated switching mechanism is arranged above the box body; the coating and cleaning integrated switching mechanism comprises a rotary switching assembly used for driving the two slit coating die heads to be switched between a coating station and a cleaning station; and the glue supply and waste discharge assembly is used for supplying glue to the coating position die head and extracting residual glue from the cleaning position die head. According to the device, through cooperation of the annular variable-diameter guide groove and the first elastic telescopic rod, automatic compensation of rotating avoiding and accurate positioning is achieved, the die head automatically avoids and resets during switching, and it is ensured that the distance between the nozzle and a base plate or a cleaning piece is constant; due to the design of the convex section, the working position is accurately butted with the cleaning position, and the thickness uniformity and the cleaning effect of a coating film are effectively guaranteed.

The utility model relates to the technical field of foam pasting, and disclose a kind of foam pasting frock, this foam pasting frock, including bottom plate, fixedly installed with conveying device on the bottom plate, the bottom plate is provided with pasting subassembly, and the pasting subassembly includes mounting bracket. This foam pasting frock, in order to make the device satisfy batch production demand, by being provided with pasting subassembly, the component cooperation horizontal electric slide rail and vertical electric slide rail collaborative drive pressing frame movement, drive adsorption head accurate alignment foam workpiece, adsorption head is pasted foam by negative pressure, avoid foam deformation when grabbing, spring rod provides buffer pressure when pasting, ensure that foam is tightly attached to workpiece on conveying device, simultaneously, the tensioning roller on support block cooperates with the vertical rod of tension spring traction and electrostatic roller, and foam workpiece is flattened and electrostatic is removed, prevent foam from adsorbing impurities due to static electricity, and collection motor drives collection rack to recycle foam waste, reduce waste accumulation.

This technical solution belongs to the field of cartoning equipment technology, specifically relating to a cartoning machine, including: a frame; a box feeding device mounted on the frame; a transfer device mounted on the frame; a lid pushing device mounted on the frame; a medical consumables feeding device mounted on the frame; a cartoning device mounted on the frame for loading medical consumables transported by the medical consumables feeding device into boxes transported by the transfer device; and a unloading device mounted on the frame. The box feeding device loads the boxes, and then the transfer device moves the boxes to the cartoning device in a set sequence to await cartoning. Simultaneously, the medical consumables feeding device performs orderly conveying and fixed-quantity sorting of the medical consumables. Finally, the cartoning device loads the fixed-quantity medical consumables into the boxes. This mechanized cartoning method improves cartoning efficiency, saves labor costs, and ensures the hygiene and safety of the consumables cartoning process and the consistency of the finished carton.

The embodiment of the utility model relates to the technical field of vehicles, and discloses a horizontal jack and vehicle assembling equipment. The horizontal jack comprises a base, a rod body assembly, a transmission mechanism and a handle. The base is suitable for being horizontally arranged, a containing cavity is limited by the base, a telescopic opening communicated with the containing cavity is formed in one end, in the axial direction, of the base, and an operation opening communicated with the containing cavity is formed in the side wall of the base; the rod body assembly is arranged in the containing cavity in the axial direction in a telescopic mode through the telescopic opening. The transmission mechanism is arranged in the containing cavity, the transmission mechanism is in transmission fit with the rod body assembly, and the transmission mechanism is opposite to the operation opening; the handle is arranged at the operation opening and is in transmission connection with the transmission mechanism so as to drive the rod body assembly to stretch out and draw back through the transmission mechanism.
