Embodiment 1

[0031] like figure 1 As shown, a sanding machine includes a conveying bed 101, a sanding device 102 and a detection device 103. The sanding device 102 is provided with a key-type sanding pad, and the key-type sanding pad includes a number of keys arranged in sequence, and the keys include The proportional electromagnet 104 and the pressing block 105 are connected to each other, and the detection device 103 includes a number of detection units corresponding to the keys. In the conveying direction 106 of the conveying bed, the keys and their corresponding detection units are located on the same straight line, and the detection unit includes at least one detection unit. The sensor that detects the passing of the board is a proximity switch or an infrared detection sensor. When a board passes under the sensor that detects the passing of the board, the sensor can detect it. Preferably, in this embodiment, the sensor that detects the passing of the board is a proximity switch.

Embodiment 2

[0036] A sanding method includes the following steps: the sensor 222 in the detection unit for detecting the passage of the plate detects whether there is a plate passing; the proportional electromagnet of the key corresponding to the detection unit outputs the pressure of P*n / m, and P is the output pressure. The full value, n is the number of sensors that detect the passing of the plate, m is the total number of sensors, the pressure of the output P*n / m is controlled by inputting the current of I*n / m to the proportional electromagnet, and I is the proportional solenoid The current required when the iron outputs P.

[0037] like Figure 4 As shown, the same parts as in the first embodiment will not be repeated, the difference is that the key-type sanding pad in this embodiment includes ten keys, which are the No. 1 key 201, No. 2 key 202, No. 3 keys 203, 4 No. 204, No. 5 key 205, No. 6 key 206, No. 7 key 207, No. 8 key 208, No. 9 key 209 and No. 10 key 210 (only the pressing ...

Abstract

The invention discloses a sander and a sanding method. The sander comprises a conveying bed, a sanding device and a detecting device. A piano type sanding pad is arranged in the sanding device, and comprises a plurality of keys arranged in sequence, each key comprises a proportion electro-magnet and a pressing block connected with the proportion electro-magnet, the detecting device comprises a plurality of detecting units corresponding to the keys, and each detecting unit comprises at least one sensor for detecting passing plates. The sander is used for sanding the surfaces of the plates, theproblem that in the prior art, an air cylinder has action errors after being used for a long time is solved, high control precision is achieved, and a control method is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of sheet metal processing equipment, in particular to a sanding machine and a sanding method. Background technique [0002] In the process of sheet metal processing, sanding needs to be carried out by a sanding machine. Sanding pads are an important part of sanding machines. Key-type sanding pads are one of the sanding pads. At present, the power of key-type sanding pads The component is a cylinder, and after a long time of use, the cylinder has an action error, that is, the output pressure cannot be accurately controlled. [0003] In view of this, this invention is proposed. SUMMARY OF THE INVENTION [0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a sanding machine for sanding the board surface, which solves the problem of the action error in the prior art when the cylinder is used for a long time, and has higher The control accuracy is high, and ...
