The invention provides a workpiece surface wiping device. An unwinding mechanism, a press roller and a winding mechanism are arranged in sequence in a mutual axial parallel manner. One end of a flexible cleaning object is wound on the unwinding mechanism while the other end of the same is wound on the winding mechanism after being wound on the press roller. A workpiece fixing mechanism is used for fixing a to-be-cleaned workpiece and arranged with the press roller at an interval, so that the flexible cleaning object wound on the press roller is located between the workpiece fixing mechanism and the press roller and clings to the press roller; the workpiece fixing mechanism is arranged movably relatively to the press roller, so that when the to-be-cleaned workpiece is fixed on the workpiece fixing mechanism, a to-be-cleaned surface of the workpiece is in contact with the flexible cleaning object wound on the press roller and moves relatively to the flexible cleaning object so as to contact with the flexible cleaning object wound on the press roller from one end to the other end successively. The invention further provides a workpiece surface wiping method. The workpiece surface wiping device is simple in structure, low in cost, small in occupied area, free of large amount of labor input, high in efficiency, good in cleaning effect and stable in workpiece quality, and can not cause scratch to the workpiece.

The invention provides a conveying device, and belongs to the technical field of automobile detection equipment. The conveying device comprises a conveying rail and adjusting structures, wherein the conveying rail is provided with a conveying surface used for conveying objects, and the adjusting structures are arranged on the two transverse sides of the conveying rail to form an adjusting channel;and in the process of conveying the objects on the conveying rail, the objects entering the adjusting channel are subjected to transverse adjustment one by one. According to the conveying device, theadjusting structures are arranged on the two transverse sides of the conveying rail, and can be used for transversely adjusting the objects conveyed on the conveying rail in the conveying process, and the adjusting structures are capable of preventing the objects from being blocked when the objects are being transversely adjusted; according to the conveying device, the position of each object does not need to be accurately detected when the position of the object is transversely adjusted, and the time to start the adjusting structures does not need to be judged, so that the whole adjusting process is convenient to adjust, the error rate is low, a wheel hub cannot be pushed slantly, so that the safety is good.

The invention discloses an idler wheel for conveying glass substrates. The idler wheel comprises a wheel main body and a peripheral member, wherein the wheel main body is provided with a convex curved surface and a groove is formed on the surface of the wheel main body and on the outermost edge, and the peripheral member is mutually embedded with the groove on the wheel main body to contact with, support and convey the glass substrates. The idler wheel provided by the invention has the advantages that the glass substrates are prevented from being scraped when being conveyed by the idler wheel; and when the idler wheel needs maintenance and repair, only the peripheral member needs to be changed instead of the whole idler wheel. Therefore, the cost is saved because the idler wheel can be repeatedly used.

The invention provides a workpiece feeding, arranging and direction arranging device and technology for sorting to-be-tidied workpieces. According to the workpiece feeding, arranging and direction arranging device, based on a plurality of stations lowered layer by layer, the gravity action of the to-be-tidied workpieces is utilized, and the multiple stations are sequentially used for conducting corresponding arranging and direction arranging operation. By adoption of the provided workpiece feeding, arranging and direction arranging device and technology, threats to operator safety during existing manual arranging can be avoided, and the problems that a vibration disc is adopted for repeated vibration and friction, product surface scratches are caused, and the quality is not good can be solved. According to the provided workpiece feeding, arranging and direction arranging device and technology, the gravity action of the to-be-tidied workpieces is utilized, the correspondingly-matched stations are matched, accordingly, the arranging and direction arranging operation on the to-be-tidied workpieces is achieved, and the cost of an integral arranging and direction arranging structure canbe lower.

The invention relates to a plastic packaging box. The plastic packaging box comprises a box body, a box cover, a connection bar and lugs, wherein the box body is connected with the box cover through the connection bar; grooves are formed in the lower end of the box body in the form of front-rear symmetry, the lugs are arranged at the upper end of the box cover in the form of front-rear symmetry, and the grooves form one-to-one correspondence with the lugs in position; and the box cover comprises a cover body, an auxiliary buckle, a clamping block, an elastic sheet and a press sheet. The invention further provides a production process for the plastic packaging box. The production process for the plastic packaging box comprises the steps of material mixing, injection die fixing, injection forming, die release, slitting, finish machining, and stacking and boxing, wherein a slitting device comprises a base plate, a workbench, a working cylinder, an installation frame, a location frame anda slitting tool. The plastic packaging box has the advantages of being firm in connection firmness for the box cover and the box body, high instability during stacking and transporting; and the slitting device has the advantages of being high in slitting accuracy, free from causing scratches to the plastic packaging box, capable of directly carrying out stacking, and the like.
