[0025] The following is a detailed description of the present invention with reference to the accompanying drawings. Figures 1 to 5 As shown, it includes a plurality of fixed workstations 1 arranged at equal intervals along a straight line, a movable transport platform 2 is provided under the fixed workstations 1, the center distance between two adjacent fixed workstations 1 is equal to the center distance between two adjacent movable transport platforms 2, a gripping device 2a is provided on the movable transport platform 2, and a connected pit 1a and a through groove 1b are provided on the fixed workstation 1. The size of the pit 1a is variable and is used to place products therein, and the through groove 1b is for the upper part of the gripping device 2a to pass vertically and horizontally. An object detection device is provided on the fixed workstation 1, and the detection range of the object detection device covers the top of the pit 1a.

[0026] The movable transport platform 2 includes a transverse slide 2b and a longitudinal slide 2c. The bottom of the transverse slide 2b is supported by a horizontal linear guide rail 2d. The side of the longitudinal slide 2c is connected to a linear bearing 2e. The linear bearing 2e is sleeved on the guide column 2f vertically connected to the transverse slide 2b. The grabbing device 2a is fixed to the longitudinal slide 2c. A pneumatic push rod 2g is arranged between the transverse slide 2b and the longitudinal slide 2c. The fixed part of the pneumatic push rod 2g is connected to the transverse slide 2b, and the movable part is connected to the longitudinal slide 2c. The movable part of the pneumatic push rod 2g is controlled to rise and fall to drive the longitudinal slide 2c to move up and down with the grabbing device 2a.

[0027] The gripping device 2a includes a pneumatic gripper 2a-1, the movable fingers of which are located above and connected to an extended gripper finger 2a-2. The extended gripper finger 2a-2 can move vertically and horizontally in the through slot 1b to clamp the workpiece and move it with the workpiece. A notch is provided at the upper end of the extended gripper finger 2a-2 where it contacts the workpiece to better clamp the workpiece.

[0028] The fixed workstation 1 includes a platform plate 1c located above the highest point of the longitudinal slide 2c. The four corners of the platform plate 1c are supported by the columns 1h. A fixed clamp 1d and a movable clamp 1e are provided on the platform plate 1c. The pit 1a and the through groove 1b are located between the fixed clamp 1d and the movable clamp 1e. The platform plate 1c and the movable clamp 1e are connected by a slide cylinder 1f. When compressed air enters the slide cylinder 1f, it pushes the internal piston to move, and the piston rod extends or retracts accordingly. The movement of the piston rod drives the slide to move in a straight line under the guidance of the guide device. By controlling the entry and discharge of compressed air, the reciprocating motion of the slide can be realized, and finally the reciprocating motion of the movable clamp 1e is controlled to cooperate with the fixed clamp 1d to loosen or clamp the workpiece in the pit 1a.

[0029] Specifically, the object detection device includes a photoelectric sensor 1g, which corresponds one-to-one with each pit 1a and detects upward. The photoelectric sensor 1g primarily consists of a light emitter and a receiver. The light emitter emits light of a specific wavelength. When the light strikes an object, some of the light is reflected or scattered by the object, and the receiver receives this reflected or scattered light. The intensity of the light signal received by the receiver determines the presence of an object. When the extended gripper finger 2a-2, carrying the workpiece, leaves the pit 1a and rises to a certain height, it is detected by the photoelectric sensor 1g.

[0030] The number of transverse slides 2b is ≥2, and two adjacent transverse slides 2b are fixed by a long hard bridge plate 2b-1. One of the transverse slides 2b is connected to a rack 2b-2, and the rack 2b-2 is engaged with the gear connected to the motor for transmission, so that one power device drives multiple groups of movable transport platforms 2 to move synchronously laterally.

[0031] An electromagnetic valve 3 is provided between the pneumatic clamp 2a-1, the pneumatic push rod 2g and the slide cylinder 1f and the air source. When the solenoid valve 3 is energized, the electromagnetic coil generates a magnetic field, attracting the valve core to move, thereby opening or closing the gas channel. By controlling the power on and off of the solenoid valve 3, precise control of the movement of the pneumatic components can be achieved. The solenoid valve 3 is provided on the bridge plate 2b-1, and the solenoid valve 3 moves synchronously with the bridge plate 2b-1. The air source and the solenoid valve 3 are connected by a hose, so there will be no interference with the movement of the bridge plate 2b-1.

[0032] As a further optimization, the extended gripper fingers 2a-2, fixed clamping block 1d, and movable clamping block 1e are all made of scissor steel, which has excellent mechanical properties, good wear resistance, and self-lubrication, allowing for long-term use under high-load and high-speed conditions. It also has a low coefficient of thermal expansion and water absorption, maintaining dimensional stability under varying temperature and humidity conditions. This ensures rigidity when gripping products while ensuring that the product is removed and placed without damaging the surface.

[0033] The workflow of the utility model technical solution is as follows:

[0034] 1: First, place the product into the pit 1a in a fixed workstation 1, and the movable clamp 1e cooperates with the fixed clamp 1d to clamp the workpiece for processing.

[0035] 2: Then, the movable clamp 1e moves away from the fixed clamp 1d to release the workpiece, the pneumatic push rod 2g lifts the grasping device 2a, the pneumatic clamp 2a-1 moves to clamp the product and stabilize it, the pneumatic push rod 2g continues to lift the grasping device 2a, the product moves upward until it leaves the pit 1a and is detected by the photoelectric sensor 1g.

[0036] 3: The motor rotates to make the gear rack 2b-2 move the movable transport platform 2 horizontally on the linear guide rail 2d.

[0037] 4: Move to the set position, the movable part of the pneumatic push rod 2g descends with the grasping device 2a, the pneumatic clamp 2a-1 opens and places the product in the pit 1a in another fixed workstation 1, and the movable clamp 1e approaches the fixed clamp 1d to clamp the workpiece.

[0038] The utility model realizes rapid displacement, precise alignment and stable fixation of products through the automated moving mechanism and cylinder clamp, improves the inaccuracy of traditional manual alignment, ensures that each workstation does not stop working during product movement, significantly optimizes the production process, improves production efficiency, and each clamping component does not damage the product surface.
