Description

Processor

Invention Field

The present invention relates to a processor.

Invention background

Generally, electronic components can be circulated in the market after undergoing tests such as durability and defect detection. In order to test the electronic components, a tester for testing the electrically connected electronic components and a device handler for electrically connecting the electronic components are required.

After the processor completes the test of the electronic components, it classifies the tested electronic components according to the test results and loads them onto the customer tray. In addition, the electronic components are tested in lots. The electronic components in lots refer to the number of electronic components loaded on a specified number of customer trays. The specified number of customer trays can be loaded in the stacker installed in the processor.

In order to prevent the loading quantity of the customer pallet loaded in the stacker from exceeding the target quantity, the processor monitors whether the customer pallet is overloaded. The processor determines whether the customer pallet is overloaded in the stacker by comparing the sum of the predetermined loading heights of the customer pallets loaded according to the specified loading quantity (hereinafter, the set loading height value) with the sum of the loading heights of the actual customer pallets loaded according to the specified loading quantity to the actual stacker (hereinafter, the actual loading height value). For example, when the difference between the actual loading height value and the set loading height value is greater than the height value of one customer pallet, the monitoring means can determine that the customer pallet is overloaded by the stacker. On the other hand, when manufacturing customer pallets, manufacturing tolerances occur in customer pallets. Due to the manufacturing tolerances, there is a difference between the set loading height value and the actual loading height value. In addition, as the loading quantity of the customer pallet increases, the difference between the set loading height value and the actual loading height value of the customer pallet loaded with the same quantity as above further increases.

The loading quantity of the customer pallet loaded in the existing stacker is less than or equal to a certain quantity. As described above, the difference between the actual loading height value and the set loading height value caused by the manufacturing tolerance of the customer pallet loaded with less than a certain quantity is less than the height value of one customer pallet. Although it is the error of the loading height value caused by the manufacturing tolerance, the reliability of the monitoring result of whether the handler is overloaded is guaranteed.

However, recently the number of customer pallets that the customer company requested to be loaded in the stacker has increased to a certain number. As the number of customer pallets loaded increases, the difference between the set loading height value and the actual loading height value may become larger than the height value of one customer pallet.

The existing processor has a problem that when the difference between the set loading height value and the actual loading height value is greater than the height value of a customer pallet, the processor will mistakenly determine that the customer pallet is overloaded in the stacker even if the customer pallet is actually loaded in the stacker according to the customer's expected loading amount. For example, when the number of customer pallets required by the customer company to be loaded in the stacker is n, and the number of customer pallets actually loaded in the stacker is n, and the sum of the manufacturing tolerances of the n customer pallets is greater than the height of one customer pallet, there is a problem that the processor recognizes that the number of customer pallets loaded in the stacker is n+1, and then mistakenly determines that the customer pallets are overloaded in the stacker.

As described above, the existing processor has a problem that even if the stacker is not overloaded with customer pallets, it mistakenly determines that it is overloaded, thereby reducing the reliability of the processor.

One embodiment of the present invention is invented with an eye on the above background, and provides a processor that improves the reliability of the processor by accurately judging whether the customer pallet loaded on the stacker is overloaded.

Detailed description of the preferred embodiment

As described below, in order to realize the technical idea of the present invention, refer to the attached drawings for detailed description of specific embodiments.

In addition, when explaining the present invention, if it is considered that a specific description of the structure or function of the relevant announcement may obscure the gist of the present invention, the detailed description will be omitted.

Furthermore, when it is mentioned that a certain constituent element is "connected" and "supported" by other constituent elements, it should be understood that it can be directly connected to or supported by other constituent elements, or that other constituent elements may exist in between.

The terms used in this specification are only used to describe specific embodiments and are not intended to limit the present invention. The expression of paragraph numbers includes plural expressions unless there is an obvious different meaning in the context.

Furthermore, terms containing ordinal numbers such as first, second, etc. can be used to describe various constituent elements, but the constituent elements are not limited to the terms. The terms are only used to distinguish one constituent element from another constituent element.

The meaning of "including" used in the specification is to specify specific features, regions, integers, steps, actions, elements and/or components, and does not exclude the existence or addition of other specific features, regions, integers, steps, actions, elements, components and/or groups.

In addition, in this manual, expressions such as upper, lower, and above are explained based on the diagrams on the drawings. If the direction of the object is changed, different expressions can be indicated in advance. In addition, the up-down direction, the front-back direction, and the left-right direction can be defined as the coordinate axes shown in Figures 1 to 5. The up-down direction can be defined as the direction of loading the customer pallet (CT). In the front-back direction, the front end can be defined as the direction of the stacker 100 toward the door 700, and the rear end can be defined as the direction opposite to the front end. In addition, the left-right direction can be defined as a direction perpendicular to the up-down direction and the front-back direction.

Below, the specific structure of the processor 1 according to an embodiment of the present invention is described with reference to the attached figure.

Referring to FIG. 1 and FIG. 2 , a processor 1 according to an embodiment of the present invention can test electronic components manufactured by a prescribed manufacturing process, and classify and load them into a customer tray (CT) according to the test results. In addition, the processor 1 can load multiple customer trays (CT) and check the loading quantity of the loaded customer trays (CT). The processor 1 may include a stacker 100, a camera 200, a lighting unit 300, a conveyor 400, a horizontal movement guide 500, a frame 600, a door 700, a driver 800, and a controller 900.

The stacker 100 may provide a loading space that can load a specified number of customer pallets (CT). The specified number may represent a maximum number of customer pallets (CT) that can be loaded in the loading space. In other words, the loading space may be defined as a space that determines the maximum number of customer pallets (CT) that can be loaded.

When the customer pallet (CT) is loaded in the loading space to the maximum extent, the upper end height of the loading space can be defined as the height of the upper end of the customer pallet (CT) loaded at the uppermost end. In addition, when the customer pallet (CT) is loaded in the loading space to the maximum extent, the lower end height of the loading space can be defined as the height of the lower end of the customer pallet (CT) loaded at the lowermost end. The stacker 100 can be arranged between the door 700 and the camera 200 in the front-rear direction. For example, the stacker 100 can be arranged at a position further back than the door 700 and further forward than the camera 200. The stacker 100 is provided in multiple numbers and can be arranged in the left-right direction. The stacker 100 can include a position sorting unit 110 and a pallet support unit 120.

Next, referring to FIG. 3 , the position sorting unit 110 can sort the positions of the customer pallets (CT) loaded in the loading space. For example, the position sorting unit 110 can prevent the customer pallets (CT) loaded in the loading space from rotating more than a specified angle or moving more than a specified distance in the horizontal direction. In this specification, the customer pallets (CT) loaded in the loading space can be named as loaded customer pallets (CTs). The position sorting unit 110 can form a loading space together with the pallet support unit 120. The position sorting unit 110 can extend in the up and down directions.

In addition, the position sorting unit 110 may be provided in plurality. The plurality of position sorting units 110 may be arranged at intervals along the left-right direction and the front-rear direction. For example, the plurality of position sorting units 110 may be arranged adjacent to each vertex of the loaded customer pallets (CTs).

The tray support portion 120 can support the loaded customer trays (CTs). The tray support portion 120 can be opposite to the bottom of the customer tray (CT) disposed at the bottom among the customer trays (CT) loaded in the loading space. In addition, the tray support portion 120 can be connected to the lower end of the position sorting portion 110.

The camera 200 can photograph the loaded customer pallets (CTs) according to a specified photographing direction. The photographing direction can be defined as the direction in which the camera 200 faces the loaded customer pallets (CTs) that are photographed. The photographing direction can be a horizontal direction that is offset from the front-rear direction and the left-right direction. In other words, by setting the photographing direction to a direction that is offset from the front-rear direction and the left-right direction in the horizontal direction, a plurality of customer pallets (CTs) loaded on the stacker 100 that are photographed by the camera 200 can be photographed. For example, when the camera 200 is observed from the upper side of the processor 1, the shooting direction is a direction misaligned with the front-rear direction and the left-right direction, and it can be a direction inclined to the left-right direction relative to the virtual line extending in the front-rear direction. As a more specific example, the angle formed by the virtual straight line extending along the shooting direction and the virtual straight line extending along the left-right direction can be less than 45°. For example, the camera 200 can be a web cam. The camera 200 can also be set at a position further back than the stacker 100. Since the camera 200 is set at the rear, the camera 200 is set to have a higher space utilization rate than when it is set in the front (between the stacker and the door), thereby preventing the expansion of the equipment. Since the camera 200 has a relatively large viewing angle and a large focal length, and is set to shoot in an oblique direction, it can be set at the rear.

4 , the camera 200 may have a specified angle of view (angle of view, a). The angle of view (a) may be defined as the field of view of a scene captured using the camera 200. The angle of view (a) may be defined as the angle formed by a virtual first straight line passing through the camera 200 and the upper end of the customer tray (CT) loaded with the maximum load and a virtual second straight line passing through the camera 200 and the lower end of the customer tray (CTs) loaded with the maximum load. For example, when the camera 200 is observed on the left or right side of the processor 1, the angle of view (a) may be defined as the angle formed between the first straight line and the second straight line. The viewing angle (a) may be determined corresponding to the front-to-back spacing distance between the camera 200 and the loaded customer pallets (CTs). For example, when the front-to-back spacing distance between the camera 200 and the loaded customer pallets (CTs) changes, the viewing angle (a) may also change accordingly. As a more detailed example, if the front-to-back spacing distance between the camera 200 and the loaded customer pallets (CTs) becomes smaller, the viewing angle (a) may become larger, and if the front-to-back spacing distance between the camera 200 and the loaded customer pallets (CTs) becomes larger, the viewing angle (a) may become smaller.

The plurality of cameras 200 may be arranged at relatively narrow intervals in the left-right direction compared to the viewing angle (a). For example, when the area within the viewing angle (a) of the camera 200 is defined as a viewing angle area, each viewing angle area of the plurality of cameras 200 may overlap with each other when viewed from above. The viewing angle area is shown in FIG5 , and three or more viewing angle areas may overlap. As described above, by installing the cameras 200 at relatively narrow intervals, space utilization is improved, and by shortening the length of the wiring connected to the cameras 200, noise that may be generated in the wiring may be minimized, thereby improving image reliability. In addition, although the plurality of cameras 200 are arranged in a relatively central area, by shooting toward the stacker in a direction tilted toward the relatively front-rear direction, the shooting distance becomes longer than when not tilted, thereby having the advantage of ensuring the focusing distance without using a focusing lens. The processor generates vibrations during operation, and since the camera 200 does not have a focusing lens, focus deviation in the focusing lens can be prevented.

The camera 200 may be spaced apart from the customer loading tray (CTs). For example, the camera 200 may be disposed at a position further back than the loading space. The camera 200 may be disposed between the upper end and the lower end of the customer loading tray (CTs) in the up-down direction.

The height h2 of the camera 200 may be lower than the height h1 of the loading customer tray (CTs). The height h2 of the camera 200 may be defined as the upper and lower spacing distance between the lower end of the loading customer tray CTs and the camera 200. In addition, the height h1 of the loading customer tray (CTs) may be defined as the upper and lower spacing distance between the upper end and the lower end of the loading customer tray CTs. As a more detailed example, the height h1 of the lens of the camera 200 may be 1/2 of the height h2 of the loading customer tray (CTs).

In addition, the camera 200 may be provided in a plurality. The plurality of cameras 200 may be provided in a number corresponding to the number of the plurality of stackers 100. The plurality of cameras 200 may correspond one-to-one to the plurality of stackers 100, respectively. For example, any one of the plurality of stackers 100 may correspond one-to-one to any one of the plurality of cameras 200. As a more detailed example, when the number of stackers 100 is n, n cameras 200 may be provided to correspond one-to-one to the n stackers 100. Any one of the plurality of cameras 200 may photograph a customer pallet (CT) loaded in any predetermined one of the plurality of stackers 100.

Next, referring to FIG. 5 , the width d2 of the plurality of cameras 200 in the left-right direction may be smaller than the width d1 of the plurality of stackers 100 in the left-right direction. The width d2 of the plurality of cameras 200 in the left-right direction may be defined as the left-right spacing distance between the camera 200 disposed on the leftmost side and the camera 200 disposed on the rightmost side among the plurality of cameras 200. In addition, the width d1 of the plurality of stackers 100 in the left-right direction may be defined as the left-right distance between the left end of the stacker 100 disposed on the leftmost side and the right end of the stacker 100 disposed on the rightmost side among the plurality of stackers 100.

The plurality of cameras 200 may include a first camera 210 and a second camera 220. The shooting direction of the first camera 210 may be oriented to the front left side as an example. The first camera 210 may be provided in plurality. The plurality of first cameras 210 may shoot a customer pallet (CT) loaded on a plurality of stackers 100 and arranged on the left side with a prescribed baseline as the center. The prescribed baseline may be defined as a virtual straight line passing through the center of the plurality of stackers 100 and extending in the front-rear direction.

The shooting direction of the second camera 220 can be, for example, the direction toward the front right side. The second camera 220 can be provided in multiple numbers. The multiple second cameras 220 can shoot the above-mentioned customer pallets (CT) loaded on multiple stackers 100 and set on the right side with the specified baseline as the center. The multiple first cameras 210 and the multiple second cameras 220 can be arranged alternately in the left-right direction.

Next, referring to FIG. 2 , the lighting unit 300 can increase the brightness of the image of the customer-loaded pallet (CTs) captured by the camera 200. The lighting unit 300 can emit light toward the customer-loaded pallet (CTs). The lighting unit 300 can emit light forward, for example. The lighting unit 300 can be disposed in front of the conveyor 400. In addition, the lighting unit 300 can be disposed at a position further back than the stacker 100 and further forward than the camera 200. In other words, the lighting unit 300 can be disposed between the camera 200 and the stacker 100 in the front-rear direction. As such, as the lighting unit 300 can be disposed in front of the conveyor 400, light emitted from the lighting unit 300 can reach the loaded customer pallets (CTs) without being interfered by the conveyor 400.

The lighting unit 300 may be configured to move along the horizontal direction (e.g., left-right direction) together with the transmitter 400. The lighting unit 300 may be an LED as an example. In addition, the lighting device 300 may be provided in multiple numbers. In order to be spaced apart in the vertical direction, the multiple lighting units 300 may be arranged adjacent to the bracket guide 420 described later.

The conveyor 400 can clamp the customer pallet (CT) loaded in the stacker 100 and convey it to the loading tray (not shown) or the unloading tray (not shown). In addition, the conveyor 400 can clamp the customer pallet (CT) on the loading tray or the unloading tray and load it on the stacker 100. The conveyor 400 can be provided in multiple numbers. The multiple conveyors 400 can be arranged in a spaced relationship in the left-right direction. The conveyor 400 can include a tray bracket 410 and a bracket guide 420. The tray bracket 410 can clamp or release the customer pallet (CT). The tray bracket 410 can be configured to move in the up-down direction relative to the bracket guide 420.

The support guide 420 can guide the vertical movement of the tray support 410. The support guide 420 can have a track as an example. The support guide 420 can extend in the vertical direction. In addition, the support guide 420 can be set at a position further back than the stacker 100. The lighting unit 300 can be set in at least one of the left and right sides of the support guide 420.

The horizontal moving guide 500 can guide the movement of the transmitter 400 and the lighting unit 300 in the horizontal direction (for example, the left-right direction). The horizontal moving guide 500 can be set at a position further back than the transmitter 400 and the lighting unit 300. In addition, the horizontal moving guide 500 can be set at a position further back than the moving frame 620 described later. In addition, the horizontal moving guide 500 can extend in the left-right direction. The horizontal moving guide 500 can be provided in plurality. Multiple horizontal moving guides 500 can be arranged spaced apart in the up-down direction.

The frame 600 may include a support frame 610 and a moving frame 620. The support frame 610 may include a first support frame 611 and a second support frame 612. The first support frame 611 may support the camera 200, the lighting unit 300 and the transmitter 400. The first support frame 611 may be disposed between the transmission device 400 and the camera 200 in the front-rear direction. For example, the first support frame 611 may be disposed in front of the camera 200 and in the rear of the transmitter 400. The first support frame 611 may extend in the left-right direction.

A horizontal moving guide 500 may be provided in front of the first supporting frame 611. In addition, the first supporting frame 611 may move in the front-rear direction relative to the second supporting frame 612. The second supporting frame 612 may support the stacker 100 and the door 700. The second supporting frame 612 may be provided at a lower side than the first supporting frame 611.

The moving frame 620 can support the transmitter 400 and the lighting unit 300. The front side of the moving frame 620 is connected to the transmitter 400 and the lighting unit 300, and the rear side can abut against the horizontal moving guide 500. The moving frame 620 can move in the left and right directions along with the horizontal moving guide 500. The moving frame 620 can move in the left and right directions together with the transmitter 400 and the lighting unit 300.

The door 700 may be connected to the front portion of the stacker 100. The door 700 may move along the front-rear direction relative to the second support frame 612 together with the stacker 100. For example, the door 700 may be introduced into or led out of the upper space together with the stacker 100. The door 700 may be provided in plurality. The plurality of doors 700 may be connected to the plurality of stackers 100, respectively. In other words, the number of doors 700 provided may be the same as the number of stackers 100 provided, and the plurality of doors 700 may be arranged in the left-right direction.

The driver 800 may drive the conveyor 400. The driver 800 may include a vertical driver and a horizontal driver. The vertical driver may move the tray bracket 410 along the bracket guide 420. The horizontal driver may move the conveyor 400 in a horizontal direction (e.g., left-right direction). For example, when the conveyor 400 moves in the left-right direction by the horizontal driver, the lighting unit 300 and the moving frame 620 may move in the left-right direction together with the conveyor 400. The driver 800 may include, for example, a belt, a roller, a motor, etc.

The controller 900 can control the camera 200, the lighting unit 300 and the driver 800. The controller 900 can determine the loading quantity of the customer pallet (CT) loaded in the loading space based on the shooting result of the camera 200. For example, the controller 900 can determine the loading quantity based on the number of tray protrusions (CTa) of the customer pallet (CT) loaded in the loading space photographed by the camera 200. The rear end portion of the customer pallet (CT) may have a tray protrusion (CTa) and a tray groove portion (CTb). The tray protrusion (CTa) may be provided at the upper portion of the rear end portion of the customer pallet (CT) and may have a shape protruding rearward. In addition, the tray groove portion (CTb) may be a groove provided below the rear end portion of the customer tray (CT). For example, when observing the rear of the loaded customer tray (CTs), the tray protrusion (CTa) and the tray groove portion (CTb) may be arranged alternately in the up-down direction. The controller (900) may determine the number of tray protrusions (CTa) photographed by the camera (200) as the number of customer trays (CT). In addition, the controller (900) may determine the tray groove portion (CTb) photographed by the camera (200) as the boundary between two adjacent customer trays (CT).

The controller 900 can be implemented by a computing device including a microprocessor. The implementation method is self-evident to those skilled in the art, so further detailed description is omitted.

The following describes the function and effect of the processor 1 according to an embodiment of the present invention.

A specified number of customer pallets (CT) can be loaded in each of the multiple stackers 100 of the processor 1. The processor 1 can determine whether the specified number of customer pallets (CT) are normally loaded according to the target number through the shooting result of the camera 200. For example, the camera 200 can shoot the customer pallets (CT) loaded on the stacker 100 as the shooting object. The loading number of the loaded customer pallets (CTs) photographed by the camera 200 can be determined by the controller 900. The controller 900 can determine that the number of the pallet protrusions (CTa) of the loaded customer pallets (CTs) photographed is the loading number of the loaded customer pallets (CTs).

In addition, when the camera 200 photographs the customer pallet (CT) loaded in the stacker 100, the lighting unit 300 can emit light to the stacker 100. Through the lighting unit 300, the camera 200 can photograph the loaded customer pallets (CTs) in a relatively bright environment. The lighting unit 300 can prevent the various devices installed in the processor 1 from causing the shooting area to be photographed by the camera 200 to become dark.

In addition, since the lighting unit 300 can move in the left-right direction together with the conveyor 400, light can be selectively emitted to a plurality of stackers 100. In other words, since there is no need to provide a corresponding lighting unit 300 for each stacker 100, the structure of the processor 1 is simplified and the manufacturing cost of the processor 1 is reduced.

Although the embodiments of the present invention are described above as specific implementation forms, this is only an example, and the present invention is not limited thereto. It should be understood that it has the broadest scope of the technical ideas disclosed in this specification. A person skilled in the art can implement unspecified shape patterns by combining/replacing the above disclosed embodiments, but this does not exceed the scope of the present invention. In addition, a person skilled in the art can easily change or deform the above disclosed implementation forms based on this specification, and it is obvious that the changes or deformations also belong to the scope of the present invention.
