The utility model discloses a positioning tool for PCBA (printed circuit board assembly) processing, which comprises a bottom plate, a controller is mounted at the front end of the bottom plate, and a carrying table is mounted at the top end of the bottom plate. Through the arrangement of the movable plate, the linear sliding rail, the cushion block, the cross rod, the rubber strip, the pull rod, the connecting plate, the electric push rod and the fixed shaft, rapid positioning of the PCBA board is achieved, the photoelectric sensor can monitor the top end of the carrying table, when the PCBA board is placed on the carrying table, the PCBA board can cover the photoelectric sensor, and the PCBA board can be accurately positioned. A photoelectric sensor can send sensing information to a controller, a system program in the controller can control an electric push rod to operate according to a control instruction, the electric push rod can stretch out and draw back to control movable plates to move horizontally in the direction of a linear sliding rail, and the two sets of movable plates are driven to move towards the center in cooperation with connection of a pull rod and a connecting plate. The rubber strips are indirectly controlled to clamp and position the two sides of the PCBA board, the machining efficiency of the positioning tool is improved, and therefore the positioning tool has the rapid positioning function.

The utility model relates to the technical field of bedside tables, and discloses a bedside table with a dust removal function, which comprises a dust removal component, a dust removal component and a dust removal component, the reciprocating screw rod is rotationally connected between the brackets; an output shaft of the motor I is fixedly connected with the front end of the reciprocating screw rod; the threaded block is in threaded connection with the reciprocating screw rod; the optical axis is arranged on the bottom surface of the bedside table through a bracket; the transverse plate is arranged on the right side wall of the threaded block, and the right end of the transverse plate is slidably connected to the polished shaft; the long brush plate is arranged on the bottom surface of the transverse plate; the springs are symmetrically arranged on the bottom surface of the transverse plate; the short brush plate is arranged at the bottom of the spring; the collecting mechanism is arranged on the left side wall of the bedside table. After a first motor is started, a linkage transverse plate moves, a long brush plate cleans dust at the bottom of the bedside table leftwards, when a short brush plate passes through the supporting legs, a spring drives the short brush plate to twist to change the direction, dust between the supporting legs is conveniently cleaned, and a collecting mechanism collects the dust cleaned out of the bottom of the bedside table.

The casting smelting waste gas treatment device with the dust removal function comprises a treatment box, an air suction fan and a filter tank, the air suction fan and a fixing plate are fixedly installed in the treatment box, a dust removal structure and an activated carbon filter screen are arranged in the fixing plate, a box door is installed on the front side of the treatment box, and a dust removal structure is installed on the box door. A pretreatment structure is mounted at the top end of the outer side of the treatment box, an air inlet pipe is fixedly mounted at the top end of the pretreatment structure, a filter tank is mounted at the bottom end of the outer side of the treatment box, and an exhaust pipe is fixedly connected to the right side of the filter tank. According to the casting smelting waste gas treatment device with the dust removal function, particle impurities in waste gas can be removed through the dust removal structure, the dust removal structure can be conveniently detached and cleaned through a fixing plate and a box door, an activated carbon filter screen can be conveniently replaced, the waste gas can be conveniently cooled through a pretreatment structure, and through a circulating pump, the waste gas can be recycled. And cooling water can be recycled, so that the cooling efficiency is improved.

The utility model relates to the technical field of optical part processing, in particular to an optical part gluing device which comprises a box body, a support is riveted to the rear side of the top of the box body, a hydraulic rod is connected to the front side of the top of the support through a bolt, and the output end of the hydraulic rod penetrates through the support and is connected with a pressure sensor through a bolt. The bottom of the pressure sensor is connected with a shell through a bolt, the top of an inner cavity of the shell is connected with a UV lamp through a bolt, and the interior of the shell is connected with a rectangular frame through a bolt. Through cooperation of the support, the hydraulic rod, the pressure sensor, the shell, the UV lamp and the rectangular frame, the gluing device has the advantage of a pressurization function, during gluing, the external controller controls the hydraulic rod to work, the output end of the hydraulic rod drives the pressure sensor and the shell to move downwards, the shell and the bottom of the rectangular frame make contact with an optical part, and therefore pressurization treatment is conducted on the optical part; and the optical parts are attached more tightly.

This utility model relates to the field of cardboard box production technology and discloses an automatic folding and forming machine for cardboard box production. It includes a processing base, a processing table installed at the bottom of the processing base, a support base installed at the top of the processing table, a door hinged to the rear end of a dust collection box, a collection mesh frame installed inside the dust collection box, and a negative pressure fan installed at the bottom of the dust collection box. This utility model, by incorporating a suction pipe, a moving frame, a fourth telescopic cylinder, and a collection mesh frame at the top of a second adsorption mechanism, allows the fourth telescopic cylinder to move above the cardboard box and adsorb dust from its surface when the cardboard box is placed above the second adsorption mechanism for folding.
