Its root mainly lies in, the limiting detection device on the conveying line, such as photoelectric switch, travel switch, once failure or response delay occurs, workpiece cannot be intercepted in time, and then easily falls from the end of the conveying line to the ground.
[0003] The current solution is more to rely on the maintenance of the limiting detection device of the output end of the conveying line to reduce the probability of workpiece falling from the end of the conveying line as far as possible, but still cannot eliminate such events, and once the workpiece falls from the conveying line, because the conveying line is often a certain height from the ground, the low one generally has about 1 meter height, for the workpiece completed machining, such height falling is easy to cause damage or even scrap of workpiece, thereby reducing the qualified rate of workpiece and increasing the cost of enterprise.

[0008] Preferably, as an improvement, an upward flange is arranged around the receiving plate, and the flange and the receiving plate jointly form a receiving groove.
[0009] Preferably, as an improvement, a drain hole is arranged in the groove bottom of the receiving groove.
[0010] Preferably, as an improvement, baffle plates are arranged on both sides of the width direction of the belt line.
[0011] Preferably, as an improvement, the input end of the conveying line is surrounded by a protective net.
[0012] Preferably, as an improvement, the four-side protection net is fixed on the support frame of the conveying line, and one side of the four-side protection net perpendicular to the conveying direction of the conveying line is provided with a discharge port for outputting the workpieces along with the conveying line.
[0013] Preferably, as an improvement, the four-side protection net is fixed on the support frame of the conveying line, and one side of the four-side protection net perpendicular to the conveying direction of the conveying line is provided with a discharge port for outputting the workpieces along with the conveying line.
[0014] Preferably, as an improvement, the four-side protection net is fixed on the support frame of the conveying line, and one side of the four-side protection net perpendicular to the conveying direction of the conveying line is provided with a discharge port for outputting the workpieces along with the conveying line.
[0015] Preferably, as an improvement, the four-side protection net is fixed on the support frame of the conveying line, and one side of the four-side protection net perpendicular to the conveying direction of the conveying line is provided with a discharge port for outputting the workpieces along with the conveying line.
[0016] Preferably, as an improvement, the four-side protection net is fixed on the support frame of the conveying line, and one side of the four-side protection net perpendicular to the conveying direction of the conveying line is provided with a discharge port for outputting the workpieces along with the conveying line.
[0017] Preferably, as an improvement, the four-side protection net is fixed on the support frame of the conveying line, and one side of the four-side protection net perpendicular to the conveying direction of the conveying line is provided with a discharge port for outputting the workpieces along with the conveying line.
[0018] In addition, because cutting fluid is used in the machining of the workpieces, after the workpieces are quickly taken out from the machining equipment by the mechanical arm, the cutting fluid will remain on the workpieces and be taken to the belt line along with the mechanical arm, and the receiving groove of the present application can receive the cutting fluid flowing down the belt line and facilitate the discharge of the cutting fluid below the drain hole.
[0019] In addition, the setting of the side plates on both sides of the belt line avoids the situation that the workpieces fall off from the side of the belt line due to the deviation of the belt in the belt conveying.
[0020] In addition, the setting of the four-side protection net not only facilitates the output of the workpieces, but also limits the area above the conveying line after the workpieces are taken out by the mechanical arm, thereby avoiding the safety risk caused by the accidental entry of workers into the unloading area of the mechanical arm.

[0024] The following is further described in detail through specific embodiments:
[0025] The reference signs in the drawings of the specification include: conveying line 1, support frame 11, limit detection switch 12, receiving plate 2, flange 21, drainage hole 22, drainage pipe 23, protective net 3, discharge port 31.
[0026] The embodiment is basically as shown in the accompanying drawings. Figures 1 to 3
[0027] A workpiece unloading device, comprising a conveying line 1, a receiving plate 2 installed below the conveying line 1, and a protective net 3 installed above the conveying line 1, the conveying line 1 being a belt line, a limit detection switch 12 being installed at the output end of the conveying line 1, and the limit detection switch 12 being detachably connected to the support frame 11 of the conveying line 1. The limit detection switch 12 is a reflection type photoelectric switch. When the reflection type photoelectric switch senses that there is a workpiece at the output end of the conveying line 1, the conveying line 1 is controlled to stop conveying.
[0028] The receiving plate 2 is fixed on the support frame 11 of the conveying line 1, the length of the receiving plate 2 extends from the side close to the input end of the conveying line 1 to the output end of the conveying line 1, and the length of the receiving plate 2 is greater than the length of one workpiece, the width of the receiving plate 2 is not less than the conveying width of the conveying line 1, and the height distance between the receiving plate 2 and the top surface of the conveying line 1 is less than 20 cm.
[0029] The front end of the receiving plate 2 extends to receive the workpiece falling from the conveying line 1 to avoid the workpiece falling directly from the conveying line 1 to the ground. The flange 21 is formed by bending the periphery of the receiving plate 2 to form a receiving groove, and the drainage hole 22 is formed at the bottom of the receiving groove of the receiving plate 2, and the drainage pipe 23 is fixed on the drainage hole 22 to facilitate the collection of cutting fluid by inserting a pipe.
[0030] The two sides of the belt line are provided with baffle plates, the baffle plates 7 are parallel to the length direction of the conveying line 1 to prevent the workpiece from falling from the side of the belt line when the belt deviates.
