[0009] As a preferred embodiment of the present invention: the detection station is also provided with: A supporting bracket, the supporting bracket is mounted on the second supporting frame; The electric telescopic cylinder is installed on the supporting frame. A supporting wheel frame is fixed on the output end of the electric telescopic cylinder, and the supporting wheel frame is located below the moving path of the positioning block.

[0010] As a preferred embodiment of the present invention: two first arc-shaped guide rods are fixed on the top of the support bracket, the two first arc-shaped guide rods are located on both sides of the supporting wheel frame, the positions of the two first arc-shaped guide rods are adapted to the arc-shaped guide seats; the ends of the first arc-shaped guide rods are in a conical structure.

[0015] The beneficial effects of the present invention are: By setting up structures such as a turntable and a carrier, the present invention can better improve the processing efficiency in a multi-station operation mode with a high degree of automation; by setting up a supporting mechanism, it can work based on the lifting drive motor to drive the lifting adjustment screw to rotate, and then control the lifting platform to rise and fall under the guidance of the guide seat, so as to better support the positioning block to facilitate the operation of the pressure output mechanism; in addition, since the support mechanism is height-adjustable and the carrier can move up and down, the compression position of the pressure output mechanism can be well controlled, thereby adapting to different production needs.

[0016] The present invention provides an arc guide seat, a second arc guide rod and other structures. When the turntable rotates, since the spacing between the two second arc guide rods is constant, when the arc guide seat slides on the outside of the second arc guide rod, the two second arc guide rods can be used to limit the two arc guide seats, thereby achieving the limitation of the two positioning blocks and maintaining the stability of the positioning blocks.

[0017] The present invention provides a detection mechanism so that the detection wheel frame can be used to perform height detection during the rotation of the turntable. If there is a situation where the structure is lifted and contacts the detection wheel frame during movement, the collision sensor will sense it in time and transmit information to the control module. Based on the control of the control module, processing of the product can be avoided, thereby improving reliability.

[0018] By providing structures such as a supporting wheel frame, the present invention can use the supporting wheel frame to provide limited support to the bottom of the positioning block when the positioning block passes through a detection station for detection, so as to ensure that the positioning block is at a normal height, thereby improving the reliability of detection.

[0019] The present invention can reliably position and limit the arc guide seat and the positioning block by setting the first arc guide rod, so as to facilitate subsequent processing, and the end of the conical structure can better guide the arc guide seat to contact with the first arc guide rod, avoiding the problem of structural jamming.

[0020] The present invention can better detect the position status of each structure by providing structures such as an arc-shaped connecting seat. When pressure processing is performed, the second arc-shaped guide rod is pressed downward, and the end of the second arc-shaped guide rod is separated from the arc-shaped connecting seat, causing the first contact and the second contact to be disconnected. When the processing is completed, the first contact and the second contact are reset based on the rebound force of the third spring, and the first contact and the second contact are connected again. The control module controls the rotation drive mechanism to continue to drive the turntable to rotate based on the change of the electrical signal, thereby improving reliability.

[0021] The present invention arranges expansion rods and top columns, so that when the turntable rotates, the two arc-shaped guide seats can slide on the outer walls of the two expansion rods respectively and be guided and limited by the expansion rods. Since the distance between the two expansion rods gradually increases in the direction away from the second arc-shaped guide rod, the distance between the two positioning blocks also increases during the rotation process, and finally the product can fall from between the two positioning blocks, thereby realizing automatic discharging and improving reliability.
