[0001] The utility model relates to the technical field of bonding detection devices, in particular to an adsorption platform for a PCB board bonding detection device. Background Art

[0002] The suction platform of a PCB bonding inspection device is used to load workpieces to be inspected. Conventional PCB bonding inspection devices utilize vacuum suction to hold the workpieces, but this method fails to effectively position the workpieces, leaving room for improvement in loading efficiency and accuracy. To address these issues, the present application proposes a novel technical solution that effectively positions the workpieces to be inspected, thereby improving loading efficiency and accuracy.

[0003] It can be seen that the existing technology still needs to be improved and enhanced. Utility Model Content

[0018] This utility model provides an adsorption platform for a PCB bonding detection device. To clarify the purpose, technical solution, and effects of this utility model, the following is a further detailed description of this utility model. It should be understood that the specific embodiments described herein are intended only to illustrate this utility model and are not intended to limit this utility model.

[0019] See also Figures 1 to 4 The present invention provides an adsorption platform for a PCB board bonding detection device. The accompanying drawings are only used to explain the structural principles and are not proportional to the actual product. The accompanying drawings only depict structures related to the invention of this application, and some conventional structures are not specifically depicted. The terms "first", "second", etc. described herein are merely different names for similar structures for the purpose of explanation and are not intended to limit this application. The "several" described herein refers to an indefinite number, because the number of structures referred to is not an invention point and is therefore not specifically limited.

[0020] An adsorption platform for a PCB bonding detection device includes a vacuum box 81 and a top plate 82, wherein a first placement area A ( Figure 4 91) and the second placement area B (corresponding to Figure 4 The first placement area is provided with a first transverse limit block 11 at both ends, and a first longitudinal limit block 12 is provided on the outward side of the first placement area; the first placement area and the second placement area are provided with a plurality of adsorption holes (such as Figure 3 101 and 102 ), each adsorption hole is connected to the vacuum box. In actual use, the vacuum box is connected to an external vacuum pumping device.

[0021] like Figure 4 As shown, the workpiece to be inspected includes a PCB board 91, a cable 92, and a screen 93 (or other components) connected in sequence. During actual loading, the PCB is located in the first placement area, and the screen (or other components) is located in the second placement area. The object of the bonding inspection is the connection between the gold fingers of the PCB board and the cable, so the PCB board needs to be positioned more accurately. In this application, by setting a first horizontal limit block and a first vertical limit block, the PCB board is limited on three sides. When loading, the PCB board can be quickly placed in the area defined by the first horizontal limit block and the first vertical limit block, thereby improving loading efficiency and loading accuracy. Since the screen is not the object of inspection, there is no need to set up a special limit block to strictly position the screen.

[0022] In practical applications, it is also possible to first place the workpiece to be inspected on a tray (not shown in the accompanying drawings) and then place the tray on the adsorption platform of the PCB bonding inspection device. To address this, the present application can also be improved as follows: two second lateral limit blocks 21 are positioned opposite each other on the top plate, and two second longitudinal limit blocks 22 are positioned opposite each other on the top plate; each first lateral limit block is positioned inside the second lateral limit block on the same side, and each first longitudinal limit block is positioned inside the second longitudinal limit block on the same side. These second lateral limit blocks and second longitudinal limit blocks can limit the tray on all four sides, allowing the tray to be easily and accurately placed on the top plate.

[0023] See also Figure 2 In actual application, in order to adapt to pallets of different sizes, the following settings can be made: the top plate is provided with two transverse guide grooves 301 corresponding to each second transverse limit block, and each second transverse limit block is inserted into the corresponding two transverse guide grooves; the top plate is provided with two longitudinal guide grooves 302 corresponding to each second longitudinal limit block, and each second longitudinal limit block is inserted into the corresponding two longitudinal guide grooves. Figure 3 and 4 It can be seen that there are several connection holes (labeled 501 and 502 in the figure) next to each transverse guide groove and longitudinal guide groove. Before use, after moving each second transverse limit block and second longitudinal limit block to the appropriate position, they are locked by connecting them to the corresponding connection holes with bolts (not shown in the figure).

[0024] Furthermore, to accommodate PCBs of varying sizes, the present application can be configured as follows: each first transverse limit block 11 is inserted into a corresponding transverse guide slot 301; each first longitudinal limit block 12 is inserted into a corresponding longitudinal guide slot 302. Similarly, after each first transverse limit block and first longitudinal limit block are adjusted to the appropriate position, they are connected to the corresponding connection holes via bolts. This configuration fully utilizes both the transverse and longitudinal guide slots, eliminating the need for additional guide slots for the first transverse limit blocks and first longitudinal limit blocks.

[0025] In actual applications, the bottom of a tray or screen may not be very flat, making it difficult for the suction holes in the second placement area to stably adhere to it. To address this, the present application can further configure the second placement area as follows: A plurality of suction cups 41 are provided in the second placement area, each of which is connected to a vacuum box 81, and the upper surface of each suction cup is higher than the upper surface of the top plate. Because each suction cup is higher than the top plate, it can always contact the bottom surface of the tray or screen, thereby achieving a good adsorption effect.

[0026] Preferably, each suction cup is provided with an elastic element (not shown) so that each suction cup can be retracted and contracted in the vertical direction. That is, after the tray or screen is placed on the suction cup, each suction cup is compressed by a certain amount to ensure that each suction cup can contact the lower surface of the tray or screen.

[0027] Preferably, each suction cup is a double-layer accordion suction cup.

[0028] In practical applications, the adsorption holes 101 of the first placement area, the adsorption holes 102 of the second placement area, and the suction cup 41 can be independently controlled, so as to be applicable to different workpieces or application scenarios.

[0029] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the present invention, and all these changes or substitutions should fall within the scope of protection of the present invention.
