The invention discloses PCBA performance test equipment. The PCBA performance test equipment comprises a supporting seat, a test execution mechanism and a self-adaptive clamping and fixing mechanism, wherein the test execution mechanism and the self-adaptive clamping and fixing mechanism are mounted on the supporting seat; the test execution mechanism comprises a rotation adjusting disc, test execution units and power transmission units, a plurality of test execution units are distributed on the rotation adjusting disc along the circumference, and the power transmission units are distributed between every two adjacent test execution units; the self-adaptive clamping and fixing mechanism comprises a rotary supporting seat, a clamping and limiting chassis, a clamping transmission device, a clamping power device and a limiting, clamping and fixing device, the clamping and limiting chassis is fixed on the rotary supporting seat, the clamping transmission device is mounted on the clamping and limiting chassis, and the limiting, clamping and fixing device is matched with the clamping and limiting chassis and the clamping transmission device. According to the invention, adaptive clamping can be carried out according to the size of the to-be-tested PCBA, the to-be-tested PCBA is subjected to plugging and bending tests through the test execution units, and the accuracy and safety of PCBA performance test are improved.

The invention relates to a reinforcement cage supporting device and a reinforcement cage seam welder. The reinforcement cage supporting device comprises a base, a connecting rod mechanism, a supporting frame, a driving mechanism and an adjusting mechanism. The connecting rod mechanism is arranged on the base. The supporting frame is installed on the connecting rod mechanism. The driving mechanismis used for driving the connecting rod mechanism to drive the supporting frame to lift. The adjusting mechanism is arranged on at least one connecting rod in the connecting rod mechanism. The adjusting mechanism is used for adjusting the length of the corresponding connecting rod according to the height relation between the reinforcement cage and the supporting frame so as to drive the supportingframe to ascend and descend. Therefore, due to the application of the reinforcement cage supporting device, the self-adaptability of the reinforcement cage of the supporting frame is enhanced while the supporting effect on the reinforcement cage is guaranteed.

The invention discloses a double-roller-shaft light blocking device. The two ends of each jacking spring correspondingly jack a bearing and an adjusting bolt of a corresponding press roller, and therefore the adaptive adjustment of the pressure of the press rollers can be achieved, then the adaptive adjustment of the production tension is achieved, the accurate detection is guaranteed, and the phenomenon that a tipping paper disc is irregularly wound is avoided. Specifically, when the pressure needs to be increased, the adjusting bolts are rotated in the forward direction, the adjusting bolts can press the jacking springs, the jacking springs are compressed, and therefore the downward pressure is applied to the bearings at the ends of the press rollers, and the purpose of increasing the pressure can be achieved. Otherwise, when the pressure needs to be reduced, the adjusting bolts are rotated in the reverse direction, the adjusting bolts can loosen the jacking springs, the jacking springs are released, and therefore the downward pressure which is applied to the bearings at the ends of the press rollers is reduced, and the purpose of reducing the pressure can be achieved.

The invention discloses a robot for automatically peeling a pineapple and peeling holes of the pineapple. The robot comprises a main frame, a material sending conveyor belt and a material discharging conveyor belt, two vertical columns, an upper horizontal frame, a lower horizontal frame, an upper horizontal electric cylinder, a lower horizontal electric cylinder, an upper vertical electric cylinder, a lower vertical electric cylinder, a U-shaped hole-peeling frame, a hole-peeling collecting box, a material sending electric cylinder and a material discharging electric cylinder, wherein the cylinder body of the upper horizontal electric cylinder is arranged on the upper horizontal frame; the cylinder body of the upper vertical electric cylinder is slidably arranged in a sliding groove of the upper horizontal frame, and the end part of a piston rod of the upper vertical electric cylinder is further provided with an upper rotating motor; the cylinder body of the lower horizontal electric cylinder is arranged on the lower horizontal frame; the cylinder body of the lower vertical electric cylinder is slidably arranged in a sliding groove of the lower horizontal frame, and the vertical electric cylinder slides in the sliding groove of the lower horizontal frame under the drive of the lower horizontal electric cylinder. According to the robot for automatically peeling the pineapple and peeling holes of the pineapple, by arranging a peeling system and a hole peeling system, the functions of automatically peeling the pineapple and peeling holes of the pineapple are achieved; by arranging adjusting mechanisms in the vertical direction and the horizontal direction, the dimension adjusting of different pineapples is achieved; the structure is reasonable and the work efficiency is high.

The invention provides an audio and video transmission control method of a network conference and a system thereof. The method comprises the following steps that: a server acquires different types of receiving parameters of a conference participant and a number of the each type of the receiving parameters is more than one; the server calculates through weighting so as to obtain the different types of the transmission parameters according to the receiving parameters and corresponding weight and the different types of the transmission parameters possess a priority order; the conference initiator transmits audio and video data to the conference participant through the server and according to the transmission parameter with a higher priority; when a variance ratio of the receiving parameters of the conference participant to the transmission parameters is larger than or equal to a preset value and the number of the conference participant whose variance ratio is larger than or equal to the preset value is greater than or equal to a preset number, the conference initiator transmits the audio and video data to the conference participant through the server and according to the transmissionparameters with a next lever in the priority order.
