This utility model discloses an ultra-long substrate carrier and an SMT assembly machine capable of processing ultra-long substrates. The ultra-long substrate carrier includes a rectangular carrier plate. A support portion is formed at the center of the top surface of the carrier plate, and a first mounting surface is formed around the support portion. The first mounting surface is enclosed by two long plate surfaces and two short plate surfaces, and several positioning portions are provided on the two long plate surfaces. By setting multiple positioning portions on the carrier, the ultra-long substrate is loaded onto the carrier, and the substrate no longer directly contacts the transport track. The transport track is stopped by any set of positioning portions blocking a sensor on the transport track, thus stopping and positioning the substrate. Multiple sets of positioning portions enable multiple stops for ultra-long substrate mounting. This allows the SMT assembly machine to produce ultra-long substrates in multiple batches, enabling the production of substrates exceeding the machine's rated size. This eliminates the need to purchase equipment with multiple rated sizes, reducing enterprise costs.

This application relates to the field of cutting tool technology, and provides a metal cutting tool with a vibration damping component, comprising a tool head and a tool shank. The tool head includes an insert and a shank, the insert being mounted on the shank, and the shank being mounted on the tool shank. A first vibration chamber is formed in the shank, and a second vibration chamber is formed in the tool shank. The first and second vibration chambers are in communication. A first damping block is disposed in the first vibration chamber, and a second damping block is disposed in the second vibration chamber. An abutment block and a first telescopic spring are disposed between the first and second damping blocks. Based on this, the first and second damping blocks move under the action of damping oil, and the abutment block and the first telescopic spring achieve a buffering effect of mutual collision, absorbing and canceling the vibration energy, thereby eliminating vibration energy and achieving the effect of vibration reduction.

The utility model provides an automatic drainage control circuit for a sump. The automatic drainage control circuit comprises a power supply, an alternating current contactor and a water pump motor which are positioned on a main loop, the first liquid level sensor, the second liquid level sensor and the interlocking switch are located on a control loop; the main loop is connected with the control loop in parallel; a power supply on the main loop is connected with a water pump motor after sequentially passing through a main contact of an alternating-current contactor and a thermal element of a thermal relay, and is connected in series with the water pump motor through the main contact of the alternating-current contactor; a first liquid level sensor on the control loop is connected in series with the automatic end of the interlocking switch; the second liquid level sensor is connected in parallel with the manual end of the interlocking switch; the first liquid level sensor and the second liquid level sensor are connected in series. When the automatic drainage device works, the interlocking switch is used for controlling the automatic control input and output of the liquid level sensor, automatic drainage of the water pump is achieved, the gradient of a pipeline does not need to be considered, and automatic starting and stopping of the water pump motor are achieved through the interlocking switch.

The application discloses a T-shaped anchor bolt mounting device and method, which comprises an anchor plate, a sleeve welded above the anchor plate for mounting a T-shaped anchor bolt, a stop and anti-sinking device welded below the anchor plate, and a sealing box welded below the anchor plate for isolating concrete; a rectangular through hole slightly larger than the T-shaped head of the T-shaped anchor bolt is formed on the anchor plate, so that the T-shaped head of the T-shaped anchor bolt can pass through the rectangular through hole at an angle coinciding with the rectangular through hole; the stop and anti-sinking device is a U-shaped round steel, and both ends of the U-shaped round steel are welded at the edges of two long sides of the rectangular through hole, so that the T-shaped head will be in contact with the U-shaped round steel after rotating a certain angle to pass through the rectangular through hole, thereby preventing the T-shaped head from continuing to rotate and preventing the T-shaped anchor bolt from sinking into the box bottom. The application has the advantages of simple structure, low manufacturing cost, convenient operation during hoisting and fixing, no need to hold the T-shaped anchor bolt by hand all the time, and good safety.
