Description

[Technical Field]

[0001] This relates to an electronic component placement tray for an odd-shaped component insertion device used in an electronic circuit board production line. [Background technology]

[0002] Conventionally, there has been a device called an odd-shaped component insertion device used in electronic circuit board production lines, which inserts components of different sizes and shapes into a single electronic circuit board. The odd-shaped component insertion device includes an insert-component placement unit that arranges insert components to be inserted into the electronic circuit board on a tray, and an electronic circuit board placement unit that places the electronic circuit board to be produced. Positional information on the leads of each insert component in the insert-component placement unit and the positional information on the insertion holes of each insert component in the electronic circuit board in the electronic circuit board placement unit are acquired in advance. When inserting an insert component, a robot is used to grasp the insert component to be inserted into the electronic circuit board based on both positional information, move it from the insert-component placement unit to the electronic circuit board placement unit, and insert the leads of the insert component into the insertion holes of the electronic circuit board.

[0003] Insert parts of the same type are arranged on a common tray, and the task of placing the insert parts on the tray is almost always done manually. This is because there are an extremely large number of insert parts, making mechanization difficult, and the number of products manufactured is often small, so manual work is actually more efficient than mechanization.

[0004] The process of arranging insert parts on trays involves manufacturing trays that fit the shape of each insert part, or printing the part positions on sponges to indicate the insertion positions, and then arranging the insert parts manually.This method takes time and effort, and also has the problem that the trays cannot be reused.

[0006] The invention of this application relates to a tray on which insertion parts used in an odd-shaped part insertion device are arranged, and an object of the invention is to provide a tray that can be used repeatedly. [Means for solving the problem]

[0007] (1) The problem is solved by an electronic component loading tray for use in an irregular component insertion device, which includes a base tray having insertion holes for inserting the leads of electronic components at equal intervals on all four sides of the surface on which the electronic components are placed, and a position display sheet that is placed on the base tray and has placement holes that indicate the placement positions of the electronic components. (2) The problem is solved by the electronic component mounting tray described in (1), characterized in that the insertion holes are provided at intervals of 2.54 mm. (3) The problem is solved by the electronic component placing tray described in (1) or (2), characterized in that the base tray has a layer made of rubber material extending parallel to the surface on which the electronic components are placed, and the insertion holes are drilled to a depth that reaches the layer made of rubber material. (4) The problem is solved by the electronic component mounting tray according to any one of (1) to (3), characterized in that the position display sheet is colored.

[0008] The leads of electronic components are inserted into the insertion holes. For this reason, the insertion holes have a diameter that allows the leads of electronic components to be inserted. Furthermore, since a large number of electronic components are inserted side by side into the base tray, the insertion holes are provided on almost the entire surface of the base tray, on all four sides of the surface on which the electronic components are placed. The spacing between adjacent insertion holes needs to match the spacing between the leads. For this reason, the spacing between adjacent insertion holes is the same. The position indication sheet has placement holes that indicate the placement position of the electronic components. When placing electronic components on the electronic component placement tray, the position indication sheet is placed on the base tray and the components are placed while indicating their positions.

[0009] The spacing between adjacent insertion holes is set to 2.54 mm because the leads of many electronic components are multiples of 2.54 mm (0.1 inch).

[0010] By providing the base tray with a rubber layer, the reed inserted into the insertion hole comes into contact with the rubber inside the insertion hole, which makes it easier for the frictional force of the rubber to maintain the position of the reed and makes it less likely for the reed to fall out.

[0011] The color of the indicator sheet makes it clear where on the base tray the electronic component should be inserted. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0013] A preferred embodiment of the present invention is outlined as follows. The present invention comprises a tray that is highly versatile and can be used any number of times, and a sheet that is easily prepared according to the size and shape of the components. The entire surface of the tray is perforated with insertion holes on the order of inches to match the lead spacing of many electronic components. The sheet is placed on the tray, and the electronic components are placed on it. The sheet has placement holes that match the size and shape of the electronic components to be inserted. The placement holes allow the worker to easily determine the position on the tray where to place the electronic components, making it easy to insert the electronic components manually. The following explanation will be given with reference to the drawings. [Example]

[0014] The odd-shaped component insertion device will be explained with reference to Figure 1. Electronic components of various sizes and shapes are mounted on electronic boards. On the electronic board production line, information on the type of electronic component to be inserted on the electronic board and the position at which it should be inserted is acquired in advance. Information on the type and position of the electronic component to be inserted is also acquired in advance. Information on which electronic components should be inserted on the electronic board and in what order is also acquired.

[0015] In a production line for electronic board 1, electronic components 5A, 5B, and 5C are inserted into predetermined positions on electronic board 1. Electronic component 5 is placed on tray 10A, electronic component 5B is placed on tray 10B, and electronic component 5C is placed on tray 10C, and each tray is placed in an electronic component placement section (not shown). Electronic board 1 is placed in the electronic board placement section (not shown). Information on the type and position of the leads of each electronic component, information on the type and position of the electronic components to be inserted into the electronic board, and information on the order in which the electronic components are to be inserted into the electronic board are stored in a memory unit (not shown) of the odd-shaped component insertion device.

[0016] An operating unit (not shown) of the odd-shaped component insertion device grasps electronic component 5A placed on tray 10A based on previously acquired position information. Based on the previously acquired position information, the operating unit moves electronic component 5A to the position on electronic board 1 where electronic component 5A should be inserted, and inserts it. Similarly, electronic components 5B and 5C are inserted into the positions on electronic board 1 where they should be inserted, respectively.

[0017] FIG. 2 shows the tray 10 and placement sheet 20 of Example 1. The tray 10 has a two-layer structure consisting of a stainless steel layer 11 and a rubber layer 12. Insertion holes 15 for inserting the leads of electronic components are drilled on almost the entire surface of the tray 10. The insertion holes 15 have a diameter of 1.2 mm so that they can accommodate the leads of electronic components. The insertion holes are deep enough to accommodate most leads and are deep enough to reach the rubber layer. Furthermore, since the leads of many electronic components are arranged in inch increments, adjacent insertion holes are drilled at a pitch of 0.1 inches (= 2.14 mm). The depth of the insertion holes 15 is adjusted to the length of the longest lead so that they can accommodate the pitch of many electronic components.

[0018] During the production process of electronic circuit boards, trays are frequently moved back and forth and side to side, which can easily cause the position of electronic components to become distorted. The trays are provided with a rubber layer so that when electronic components are inserted into the insertion holes, the leads are properly gripped and the position of the electronic components is maintained.

[0019] The placement sheet 20 is suitably made of polypropylene. The placement sheet 20 has placement holes 20 that indicate the positions where the electronic components are to be placed. As shown in Figures 3 and 4, the tray 10 has positioning protrusions 14 for determining the position where the placement sheet 20 is placed. Figure 4 shows the tray 10 from directly above, Figure 5 shows the placement sheet 20, Figure 6 shows the state where the placement sheet 20 is placed on the tray 10, and Figure 7 shows the state where the electronic components 5 are inserted via the placement sheet 20, all of which are shown from directly above.

[0020] The position, shape, and size of the placement holes in the placement sheet are determined depending on how the electronic components are inserted into the tray. For example, in the case shown in Figures 4 to 7, the space occupied by one electronic component 5B on tray 10 is three insertion holes vertically and three insertion holes horizontally. Taking into account factors such as avoiding collisions when the electronic components are moved on the production line, it was determined that three insertion holes was appropriate for the gap between the electronic components, and placement holes 25 as shown in Figure 5 were provided. As shown in Figures 6 and 7, the position, shape, and size of such placement holes 25 are suitable for placing electronic components 5B on tray 10.

[0021] The work of placing the placement sheet 20 on the tray 10 and the work of inserting the electronic components 5B into the tray 10 with the placement sheet 20 placed on it are performed manually. The placement sheet is placed on the tray 10 using the positioning protrusions 14. The placement of the electronic components is easy because the placement sheet 20 indicates the location where the electronic components should be inserted. While FIG. 7 shows a state in which three electronic components have been placed, the placement of electronic components continues, and the number of electronic components used in the production line for the electronic board 1 is placed on the tray 10.

[0022] If the spacing between the leads of the electronic components is not a multiple of 0.1 inches or the lead diameter is 1.2 mm or greater, the leads cannot be inserted into the insertion holes, and therefore the tray 10 is not suitable for use. Furthermore, if the electronic component has a protrusion on its bottom surface or for other reasons that would cause the electronic component to tilt when inserted into the tray 10, the tray 10 is also not suitable for use. For electronic components other than those described above, the tray can be reused any number of times. While placement sheets according to the size and shape of the electronic components are required, these placement sheets are easy to manufacture.
