Description

1238450 V. Description of the invention α) [Technical field to which the invention belongs] This case refers to a conveying device for cutting a thin-film substrate in which a matrix of electronic components is arranged in a matrix shape (cutting once) and cutting again (secondary cutting) A cutting machine for obtaining the wafer data therein, in particular, a conveying device that can convey the sheet-shaped components placed in the storage box after the primary cutting to the secondary cutting machine piece by piece. [Prior Art] The process of manufacturing a chip module of a fixed resistor or a variable electric group has been shown in FIG. 9 all the time. That is, on the wafer substrate S in which the data matrix of the wafer t is arrayed and burned, vertical grooves are provided around the data of the wafer t. Next, the module W (a secondary cutting) is first cut from the longitudinal grooves into a narrow (hereinafter referred to as a thin sheet), and then cut into individual wafer modules t from the horizontal grooves (secondary cutting). Between the first cutting and the second cutting, there is a work of transporting the front and back of the module W (eg, the recording surface is the front side). The transport device used in this transport operation can be used in Kaiping 1 1 1 6 It is known in 0 3 6. The data of Japanese Patent Laid-Open Publication No. 1 1 16 0 36 is shown in FIG. 10. 5 0 is the receiving table, and 5 1 is a cylindrical drum. A plurality of grooves 5 2 are engraved on the inner ring of the drum 51 in the direction of the shaft and can be fitted with the module W in the direction of the shaft. Put the module W into the drum 51 to perform the operation. Although the module W will first stay in the component concentration area E of the lowest A of gravity, it can be rotated in the direction of the arrow by the rotation and stirring of the drum 51 in the direction of the arrow. Transported and fitted with grooves 5 2. Every time the drum 5 1 rotates more than 1/4 turn from the point A, the component W may fall due to gravity. Therefore, the suction groove 5 4 is designed to maintain a negative pressure inside.

111 · III IIIKIRII iliill · III S? Outline of anti-malignant ® Hi Press II Page 6 1238450 V. Description of the invention (2) The module W is held by the suction hole 5 3 designed in the groove 5 2 Location of groove 5 2. Next, before the roller 51 moves from point B to point C, the peephole provided on the groove 5 2 uses the suction hole 5 3 to inspect the front and back of the module W by an inspection device (such as a light sensor). an examination. As a result, the applicable components are separated from the grooves 52 by the nozzles 55 provided at the top point C of the drum through the suction holes 53 and sent to the next job by the conveyor er 5 6 in the drum 51 ( Secondary cutting). In addition, the module W which is judged to be unsuitable will pass through the point C and reach D downstream of the communication suction groove 54 directly because the nozzle 55 of the vertex C cannot spray. Although the module W will stay in the groove 5 2 due to the suction of the communication suction groove 54 before reaching the point D, as long as it passes the point D because the suction of the suction hole 5 3 is missing, it will fall back to the module detention due to gravity. E Redo the job again. Because the opening at the front of the lowermost part A of the roller 51 is higher and the opening at the rear is lower, the component W to be moved will move toward the rear opening and be blocked by the receiving table 50 and stay at the rear of the roller 51. The space between the inner wall near the opening and the receiving desk. However, all the current transportation devices have the following problems. 1 / The module W is easy to be broken (or easy to be injured). The electronic module t, which is a module, is getting thinner and smaller, such as the size of 1 0 0 5 is 1 below mm, thickness below 0.5 mm, and the length of specification 0 6 0 3 is below 0.6 mm, thickness is below 0.3 mm) If a groove is formed in such a thin circuit board, the force will be weakened due to stress concentration. Also less resistant to impact. ★ Easy to break when falling after passing point D. 2 / groove 5 2 The storage accuracy of the 2 pair module W is low.

1238450 V. Explanation of the invention (3) ★ It is difficult to store because there is no certain direction when investing. ★ Even if it is put along the groove 52, it will be easier to turn when the module W hits the receiving table 50 because it is lower than the opening at the front end (that is, it intersects with the groove 52). 3 / Difficulty in speeding up: The rotation speed has its limit. To increase the speed of the drum, increasing the rotation speed of the drum 5 1 will cause the following problems. ★ The centrifugal force caused by the rotation will make some inapplicable components. 2 came out and couldn't handle it. ★ The component W will fall from a higher height for mixing and is therefore easily broken. If the speed is further increased, the component W will become unable to stir. 4 / It is difficult to adjust the jet force. If the jet force of the nozzle 5 is smaller than the attraction force, the module W cannot be separated by the groove 5 2. c ο nveyer) The reaction force at 5 6 is reversed so that the front and back are reversed or dropped outside the conveyor 5 6. In addition, the adjustment of the jet force is more difficult because of the influence of the jet time on the jet time. 5 / The size of the groove W 2 of the component W must be changed, and the roller 5 1 must be replaced. The object of the invention of the present invention is to provide a conveying device which enables a module to be conveyed at a high speed without being injured and also freely corresponds to the size of the module. [Summary of the Invention] The idea of this case is a supply method of pushing the aforementioned components upward from the bottom of the storage box to supply the components, and vacuuming the supplied components to the rear
