Grooves (for vertical division and horizontal division) are formed in predetermined dimensions corresponding to the dimensions of the chip in advance, and a material sheet t ″ having a resistive film formed on the surface is vertically divided in a primary dividing step to form a narrow elongated plate. A raw material bar t 'is provided, and a paste for an electrode (for example, silver palladium paste) is applied to both longitudinal sides of the raw material bar t' by appropriate means, dried through a drying furnace, and then subjected to a secondary splitting process.

ね共通しており、夫々効率を上げているが、In the above-mentioned manufacturing process, a step of providing a material sheet and vertically dividing the material sheet in a primary splitting step to provide a material bar, and drying the material bar on which the electrode paste has been applied in a drying furnace, The process of finishing each chip type resistor by dividing it horizontally in the secondary splitting process is generally common to each of the conventional technologies, and the efficiency is increased respectively.

来、下記のように行われており、夫々に課題が存在して
いる。The electrode coating process for efficiently and accurately applying the electrode paste to both side surfaces of the vertically divided material bar has been conventionally performed as described below, and each has its own problems.

ず、それらの能力を減殺してしまっている欠点があっ
た。The first method is to pick up a material bar, which is vertically divided and sent one by one by a conveyor or the like, by a moving chuck or the like, and if the electrode paste is squeezed flat on a flat surface. Move, descend, contact and apply paste on one side of the material bar, rise, reverse, descend,
The coating is performed on the opposite side by contact, and since this is performed for each material bar, the efficiency is extremely low. In particular, the processing speed is limited, and the material is subjected to the previous process (the material after the primary splitting process). There was a drawback that the speed of feeding the bar) and the speed of the next process (drying of the coated material bar by a conveyor or the like) could not be coped with, and their abilities were reduced.

済な難点があった。The second problem is that a set number of material bars vertically divided in the primary splitting process are set on a jig board, and in this state, the electrode paste is simultaneously applied to all the material bars of the jig board. Although common to the invention, in the conventional case, after the coating process is completed, the jig board is dried through a drying furnace while the material bar is set on the jig board, and sent to the secondary splitting step. Therefore, the material bars which are vertically divided and fed are set one after another on a new jig board, so that an expensive jig configured with high precision is used. There was an extremely uneconomical disadvantage in that a large number of boards (100 or more) were required.

な対策が強く望まれてきたものである。In each of the above two examples, when the electrode paste is applied to the side surface of the raw material bar, the raw material bar descends with respect to the paste extended on the plane below the raw material bar.
It is a method of applying by contact, but the material bar is extremely small and made of ceramic and is very brittle, so it is often damaged during work, so fragments of the material bar etc. fall and scatter on the paste and become In addition to adhering and mixing, the paste becomes useless, and serious accidents often occur in which all the material bars to which the paste is applied become defective, and effective countermeasures have been strongly desired.

The present invention provides a unique jig board and the jig. The above problem is solved by an electrode coating device which is configured by disposing an electrode paste supply device and a material bar lifting plate centering on a plate, and in this device, the flattened paste is applied to a jig plate (ie, This problem has been solved by providing the jig board so as to be positioned above the material bar) so as to contact (apply) the jig board up (as opposed to the conventional one).

した良好な塗布を行い得る。When the paste is applied by pressing the side of the material bar against the paste film, the shape and the like of each material bar may be slightly different or deviated. In this regard, the present invention is provided with the lifting pins elastically supported by springs, respectively, relative to the individual material bars, so that the spring resilience of the lifting pins acts separately for each material bar. As a result, it is possible to perform good application corresponding to each material bar.
