[0003] The chip transfer device includes a first conveying track and a second conveying track, and the second conveying track is used for conveying a frame containing chips. The input end of the second conveying track is connected to the output end of the first conveying track, and the second conveying track is used for conveying chips. When the width of the first track is debugged, the frame needs to be placed on the first conveying track to ensure that the buckle on the frame can be normally opened and closed for taking and placing the chips. If the distance between the frame and the side of the first conveying track is too large, it will affect the accuracy of the position of the frame on the first conveying track and affect the subsequent operation of the mechanical gripper. When the width of the second conveying track is debugged, the chip needs to be placed on the second conveying track, and then the chip is manually pushed to slide in the second conveying track.

[0032] To solve the problems in the prior art, the application provides a positioning jig and a chip transfer device, which can quickly and accurately complete width adjustment of a first conveying track and a second conveying track in the chip transfer device, and the operation is simple.

[0033] As shown in Figure 1-5 The embodiment of the application provides a positioning jig 4 applied to a chip transfer device, the chip transfer device comprising a first conveying track 1 and a second conveying track 2, the first conveying track 1 being used for conveying a frame 3 provided with a carrier plate, the frame 3 being provided with a buckle 31 for controlling opening and closing of an opening 33 of the frame 3, an input end of the second conveying track 2 being connected to an output end of the first conveying track 1, the second conveying track 2 being used for conveying the carrier plate, the positioning jig 4 comprising a first positioning part 41 and a second positioning part 42, the first positioning part 41 being used for positioning a width of the first conveying track 1, a length of the first positioning part 41 being equal to a sum of a length of the frame 3 and a first reserved length of opening and closing of the buckle 31, the second positioning part 42 being used for positioning a width of the second conveying track 2, a length of the second positioning part 42 being equal to a sum of a length of the carrier plate and a second reserved length, the second reserved length being a standard gap between the carrier plate and the second conveying track 2.

[0034] In this application, the width of the first conveying track 1 is positioned by the first positioning portion 41, and the length of the first positioning portion 41 is equal to the length of the frame 3 plus the first reserved length for the opening and closing of the buckle 31. Therefore, the width of the first conveying track 1 can be accurately positioned, and the width of the second conveying track 2 is positioned by the second positioning portion 42. The length of the second positioning portion 42 is equal to the length of the carrier plate plus the second reserved length. Therefore, the width of the second conveying track 2 can be accurately positioned, thereby realizing the rapid and accurate completion of the width debugging of the first conveying track 1 and the second conveying track 2 in the chip transfer equipment, and the operation is simple.

[0035] Specifically, the frame 3 is transported through the first conveying track 1. A multi-layer carrier is provided in the frame 3, and the carrier is loaded with chips. A robot is required to move the carrier in the frame 3 to the second conveying track 2. The carrier is transported through the second conveying track 2, and then the chip on the carrier is photographed and positioned by a shooting camera.

[0036] Currently, when adjusting the width of the first and second conveyor tracks 1 and 2, the equipment must be mailed to the manufacturer, which is time-consuming and unreliable. Furthermore, the frame 3 and carrier are confidential fixtures, which could easily leak company secrets. After the manufacturer's adjustment, further verification is generally required. Currently, when adjusting the width of the first conveyor track 1, the company must place the frame 3 inside the first conveyor track 1 and then open the latches 31 at each end of the frame 3 to ensure that the latches 31 can open properly. If the width is too small, the latches 31 may not open properly. If the width is too large, the mechanical gripper may not be able to accurately grasp the correct position, causing the equipment to alarm. Currently, adjusting the width of the first conveyor track 1 mainly relies on manual feel. When adjusting the width of the geothermal conveyor track, the company must place the carrier plate inside the second conveyor track 2 and then manually push the carrier plate to slide within the second conveyor track 2, determining whether the carrier plate slides smoothly within the second conveyor track 2 based on manual feel. There is no fixed standard for spacing. If the spacing is too small, it can easily cause "board jamming," where the carrier board gets stuck in the second conveyor track 2. If the spacing is too large, the carrier board cannot be fixed in the same position during camera shooting, affecting the accuracy of subsequent shooting and positioning. Moreover, directly using the frame 3 and carrier board for debugging can easily damage the frame 3 and the carrier board, resulting in a waste of resources.

[0037] In the present application, the width of the first conveyor track 1 is determined by a first positioning portion 41. The length of the first positioning portion 41 is equal to the length of the frame 3 plus a first reserved length for the latches 31 at both ends of the frame 3 to open and close. The length of the frame 3 is the length along the width of the first conveyor track 1 after the frame 3 is placed in the first conveyor track 1. The first positioning portion 41 can accurately determine the width of the first conveyor track 1 to ensure that the latches 31 can open and close normally, while also ensuring that the mechanical gripper can accurately grasp the correct position. The width of the second conveyor track 2 is determined by a second positioning portion 42. The length of the second positioning portion 42 is equal to the length of the carrier plus a second reserved length. The length of the carrier is the length along the width of the second conveyor track 2 after the carrier is placed in the second conveyor track 2. The second reserved length is a safety distance. This allows for precise control of the width of the second conveyor track 2 to ensure that the carrier can slide smoothly within the second conveyor track 2 and to ensure the accuracy of the carrier's position when it is transported to the camera position within the second conveyor track 2, thereby ensuring the accuracy of subsequent shooting positioning. Furthermore, there is no need to use the frame 3 and the carrier board for debugging, thereby reducing damage to the frame 3 and the carrier board.

[0038] In some embodiments, the first positioning portion 41 is a first side of the positioning fixture 4 along the length direction, and the second positioning portion 42 is a second side of the positioning fixture 4 along the width direction.

[0039] In this application, the positioning fixture 4 is a rectangular plate, the first side of which is a first positioning portion 41, which is used to position the width of the first conveying track 1. The second side of the rectangular plate is a second positioning portion 42, which is used to position the width of the second conveying track 2. The structure is simple and easy to operate.

[0040] In some embodiments, the first conveying track 1 and / or the second conveying track 2 includes multiple conveying units 24, and the multiple conveying units 24 are arranged at intervals along the conveying direction; the positioning fixture 4 also includes a third positioning portion 43, and the third positioning portion 43 is used to locate the gap between two adjacent conveying units 24.

[0041] In the present application, the first conveying track 1 and the second conveying track 2 may include multiple conveying units 24, and the multiple conveying units 24 are arranged in sequence along the conveying direction, and there is a gap between two adjacent conveying units 24. The gap between two adjacent conveying units 24 is positioned by the third positioning part 43 on the positioning jig 4, thereby further improving the positioning function of the positioning jig 4.

[0042] Specifically, the second conveying track 2 in the present application includes multiple conveying units 24. Since the second conveying track 2 is used to convey the carrier, the chips on the carrier need to pass through multiple processing positions. Therefore, the length of the second conveying track 2 needs to be set long enough to ensure that the chips on the second conveying track 2 can be processed multiple times at the same time.

[0043] In the related art, there is no standard for adjusting the gap between the conveying units 24, and the adjustment is performed by visual inspection, which is low in efficiency and poor in positioning accuracy. If the gap between the two adjacent conveying units 24 is too large, the particles in the workshop will affect the product; if the gap is too small, the track conveying will be not smooth, affecting the normal conveying of the product and the subsequent adjustment.

[0044] In the embodiment of the present application, the gap between the two adjacent conveying units 24 is adjusted by the third positioning part 43, which can accurately position the gap and is simple to operate.

[0045] In some embodiments, the third positioning part 43 is a third edge of the positioning jig 4 in the thickness direction.

[0046] In the present application, the positioning jig 4 is a rectangular plate, and the third edge in the thickness direction is the third positioning part 43, so that the overall structure of the positioning jig 4 is simple and convenient to operate.

[0047] Specifically, the first edge of the rectangular plate in the length direction is the first positioning part 41, and the second edge in the width direction is the positioning part. Alternatively, the first positioning part 41 can be in the width direction of the rectangular plate, and the second positioning part 42 can be in the length direction of the rectangular plate.

[0048] In some embodiments, the positioning jig 4 has a plurality of third edges in the thickness direction, and the plurality of third edges are respectively used to position two conveying units 24 with different gaps.

[0049] In the present application, the positioning jig 4 has a plurality of third edges in the thickness direction, so that the required third edge can be selected according to different types of conveying units 24. Specifically, the gap between the two adjacent conveying units 24 of the first conveying track 1 is different from the gap between the two adjacent conveying units 24 of the second conveying track 2, and two third edges are respectively arranged to correspond to the gap between the two conveying units 24 of the first conveying track 1 and the gap between the two conveying units 24 of the second conveying track 2.

[0050] In some embodiments, the third edge has a placing part 44 placed on the conveying unit 24, and the positioning jig 4 is provided with a level 45.

[0051] In the present application, after the placing part 44 of the third edge is placed on the conveying unit 24, the levelness of the conveying unit 24 can be adjusted according to the level 45, and then the levelness and height of the conveying unit 24 are adjusted.

[0052] Specifically, the bottom of the conveying unit 24 is generally provided with adjustable feet at the four end corners, and the height of a certain end corner of the conveying unit 24 can be adjusted by the adjustable feet. When the height of one end of the conveying unit 24 along the conveying direction needs to be adjusted, the positioning jig 4 needs to be placed on the two conveying units 24, that is, one end of the positioning jig 4 is placed on the fixed conveying unit 24, and the other end is placed on the conveying unit 24 that needs to be adjusted, and then the height of the conveying unit 24 that needs to be adjusted is adjusted by the level 45. When one end of the conveying unit 24 needs to be horizontally adjusted along the width direction, the gap between the two conveying units 24 is positioned by the third side. At this time, the placing part 44 is placed on the conveying unit 24 that needs to be adjusted, and the horizontal degree of the conveying unit 24 that needs to be adjusted is adjusted by calibrating the level 45 to ensure its horizontality. The horizontal adjustment of the conveying unit 24 can be completed while the spacing adjustment of the conveying units 24 is completed.

[0053] The positioning jig 4 positions the width of the first conveying track 1 through the first positioning portion 41. The length of the first positioning portion 41 is equal to the length of the frame 3 plus the first reserved length for the opening and closing of the buckle 31. Therefore, the width of the first conveying track 1 can be accurately positioned. The width of the second conveying track 2 is positioned through the second positioning portion 42. The length of the second positioning portion 42 is equal to the length of the carrier plate plus the second reserved length. Therefore, the width of the second conveying track 2 can be accurately positioned, thereby realizing the rapid and accurate completion of the width debugging of the first conveying track 1 and the second conveying track 2 in the chip transfer equipment, and the operation is simple.

[0054] like Figure 1 and 5 As shown, an embodiment of the present application provides a chip transfer device, including: a frame 3, in which a support portion 32 for carrying a carrier is provided, openings 33 for the carrier to enter and exit are provided at both ends of the frame 3, and a snap 31 is provided at the opening 33, and the snap 31 is used to control the opening and closing of the opening 33; a first conveying track 1, and the first conveying track 1 is used to convey the frame 3; a second conveying track 2, the input end of the second conveying track 2 is connected to the output end of the first conveying track 1, and the second conveying track 2 is used to convey the carrier; and the above-mentioned positioning fixture 4.

[0055] In the present application, the first conveying track 1 is used to convey the frame 3, and the support portion 32 in the frame 3 is used to carry the carrier. The carrier enters and exits through the opening 33. The opening and closing of the opening 33 can be controlled by the buckle 31. When the buckle 31 is in the closed state, the carrier cannot be exported through the opening 33. When the opening 33 is in the open state, the carrier can be exported through the opening 33. The frame 3 with the carrier is conveyed by the first conveying track 1 to the input end of the second conveying track 2, and then the buckle 31 is opened, and the carrier is moved to the second conveying track 2 by the mechanical claw. The carrier is conveyed by the second conveying track 2. The carrier is equipped with a chip, so that the chip passes through multiple processing positions on the second conveying track 2 in sequence to complete the processing and detection of the chip.

[0056] Specifically, the positioning jig 4 is an accessory of the equipment, and is specifically designed according to the specific settings of the first conveying track 1 and the second conveying track 2. By adopting the positioning jig 4 in this application, the width adjustment of the first conveying track 1, the width adjustment of the second conveying track 2, and the adjustment of the spacing between the conveying units 24 can be completed quickly and accurately.

[0057] In some embodiments, the first conveying track 1 includes: two first side plates 11 arranged opposite to each other, forming a first conveying space for conveying the frame 3 between the two first side plates 11; a first adjustment component 12, used to adjust the distance between the two first side plates 11; and a first conveyor belt 13, arranged in the first conveying space, used to convey the frame 3 in the first conveying space.

[0058] In this application, when the width of the first conveying track 1 needs to be adjusted, the positioning jig 4 is placed in the first conveying space of the first conveying track 1, and the first edge of the positioning jig 4 is set along the width direction of the first conveying space. The spacing between the two first side panels 11 is adjusted by the first adjustment component 12, so that the two first side panels 11 are respectively fitted with the two ends of the first edge of the positioning jig 4, and the positioning of the width of the first conveying track 1 can be completed. Then, the two first side panels 11 are fixed, and the positioning jig 4 is removed for easy operation, so that the first conveying track 1 can be accurately positioned.

[0059] In some embodiments, the second conveying track 2 includes: two second side plates 21 arranged opposite to each other, forming a second conveying space for conveying chips between the two second side plates 21; a second adjustment component 22, used to adjust the distance between the two second side plates 21; and a second conveyor belt 23, arranged in the second conveying space, used to convey the carrier in the second conveying space.

[0060] In this application, when the width of the second conveying track 2 needs to be adjusted, the positioning jig 4 is placed in the second conveying space of the second conveying track 2, and the second long side of the positioning jig 4 is set along the width direction of the second conveying space. The spacing between the two second side panels 21 is adjusted by the second adjustment component 22, so that the two second side panels 21 are respectively fitted with the two ends of the second side of the positioning jig 4, so that the positioning of the width of the second conveying track 2 can be completed, and then the two second side panels 21 are fixed, and the positioning jig 4 is removed for easy operation, so as to achieve precise positioning of the second conveying track 2.

[0061] In some embodiments, the first conveying track 1 and / or the second conveying track 2 includes a plurality of conveying units 24 , and a gap is left between two adjacent conveying units 24 .

[0062] In the present application, the first conveying track 1 and the second conveying track 2 can both include multiple conveying units 24, and the spacing between the conveying units 24 can be positioned by the third side of the positioning fixture 4, thereby facilitating the debugging of the spacing between two adjacent conveying units 24 of the first conveying track 1 or the second conveying track 2.
