[0020] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0021] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that, in the absence of conflict, the features in the following embodiments and embodiments can be combined with each other. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative work are within the scope of protection of this application.

[0022] like Figure 1 As shown, an embodiment of the present invention provides an adjustable, fully automatic placement machine bulk electronic chip tray, comprising a tray support 1, a transverse movable beam 2, and a longitudinal movable beam 3. A guide rail 11 is provided on the inner periphery of the frame of the tray support 1; both ends of the transverse movable beam 2 are slidably connected to corresponding groove rails 11, and a limit groove 6 is provided on the bottom surface of the transverse movable beam 2; both ends of the longitudinal movable beam 3 are slidably connected to corresponding groove rails 11, and a matching groove 7 is provided on the top surface of the longitudinal movable beam 3 to match the limit groove 6. The moving direction of the transverse movable beam 2 and the moving direction of the longitudinal movable beam 3 form an angle, and this angle is a minor angle.

[0023] The present invention has a simple structure and can arbitrarily adjust the length and width between the transverse moving beam 2 and the longitudinal moving beam 3 according to the size of the components. By uniformly placing the components in the small squares of the IC tray according to the picking direction, batch production of the fully automatic placement machine is achieved.

[0024] Specifically, the embodiment of the present application provides an adjustable tray for bulk electronic chips of a fully automatic placement machine, which can be used in conjunction with the MY300 fully automatic placement machine. A groove track 11 is provided on the inner side of the frame of the tray bracket 1, and the transverse moving beam 2 and the longitudinal moving beam 3 can move in the groove track 11, and a single-step movement is adopted when moving. The above-mentioned single-step movement method is specifically: first moving the transverse moving beam 2 as a whole and then moving the longitudinal moving beam 3, or first moving the longitudinal moving beam 3 as a whole and then moving the transverse moving beam 2, so as to ensure the relative movement of the transverse moving beam 2 and the longitudinal moving beam 3 and the stability of the generated grid structure. Furthermore, there is an angle between the moving direction of the transverse moving beam 2 and the moving direction of the longitudinal moving beam 3, and the angle is a minor angle (greater than 0° and less than 180°). In the embodiment of the present application, it is preferred that the angle is a right angle. In another embodiment, the angle is any angle other than a right angle among the minor angles.

[0025] The present invention provides an adjustable, fully automatic placement machine bulk electronic chip tray. Guide rails are provided within the tray support. Both horizontal and vertical beams are slidably connected to the tray support via the rails. The horizontal and vertical beams engage with each other via serrated grooves, enabling relative limited movement. The adjustable horizontal and vertical beams enable storage of components of various specifications. This, combined with fully automatic placement equipment, allows for efficient, high-quality placement of bulk materials of various specifications.

[0026] Preferably, the cross-section of the groove rail 11 is L-shaped, and both ends of the transverse moving beam 2 and the longitudinal moving beam 3 are provided with L-shaped slots 5 that cooperate with the L-shaped groove rail 11 .

[0027] Specifically, if Figure 2 and Figure 3 As shown in the embodiment of the present invention, the transverse moving beam 2 and the longitudinal moving beam 3 are slidably connected by the L-shaped slots 5 at both ends of the beams and the groove rails 11, ensuring that the moving beams move in the same direction. Figure 4 As shown. The cross-section of the groove rail 11 and the retaining slot 5 is L-shaped, ensuring a tighter and more secure sliding fit between the transverse movable beam 2 and the longitudinal movable beam 3. In other embodiments, the cross-section of the groove rail 11 and the retaining slot 5 can be C-shaped, T-shaped, or other shapes. In practice, the transverse movable beam 2 and the longitudinal movable beam 3 can be adjusted to suit the size of the components. By uniformly placing the components in the small squares of the IC tray according to the pick-up orientation, mass production can be achieved using a fully automatic placement machine.

[0028] Furthermore, the first clearance is defined as the clearance between the groove rail 11 and the transverse movable beam 2, and the second clearance is defined as the clearance between the groove rail 11 and the longitudinal movable beam 3. The first clearance and the second clearance are equal. In the embodiment of the present application, the range of the first clearance and the second clearance is 0.4 mm to 0.6 mm.

[0029] Specifically, the transverse moving beam 2, the longitudinal moving beam 3 and the groove rail 11 are all clearance-fitted. By controlling the fitting clearance to be between 0.4 mm and 0.6 mm, the tightness of the transverse moving beam 2 and the longitudinal moving beam 3 when they slide relative to the groove rail is ensured, thereby improving the reliability of the IC tray.

[0030] Preferably, the limiting groove 6 of the transverse moving beam 2 and the matching groove 7 of the longitudinal moving beam 3 are both serrated grooves, and the groove depths and groove spacings of the limiting groove 6 and the matching groove 7 are the same.

[0031] Specifically, if Figure 2 and Figure 3As shown, the embodiment of the present application is based on the principle of inter-tooth engagement, and the transverse moving beam 2 and the longitudinal moving beam 3 are connected by a sawtooth groove to achieve relative movement. The limiting groove 6 and the matching groove 7 are both sawtooth grooves, which play a guiding and limiting role in the relative movement of the transverse moving beam 2 and the longitudinal moving beam 3, ensuring that the transverse moving beam 2 moves in the same plane and in the same direction relative to the longitudinal moving beam 3, and the groove depth and the groove spacing are the same, thereby ensuring that the size of the discharge tray is consistent during the movement of the transverse moving beam 2 and the longitudinal moving beam 3. In another embodiment, the tooth groove shape of the limiting groove 6 and the matching groove 7 can also be an arc tooth groove, an oblique tooth groove, etc. In the embodiment of the present application, the groove depth of the limiting groove 6 and the matching groove 7 is preferably 0.8mm to 1mm.

[0032] Furthermore, there are multiple transverse moving beams 2 and longitudinal moving beams 3, the top surfaces of the multiple transverse moving beams 2 are all located in the same plane, and the multiple transverse moving beams 2 are arranged in parallel and spaced apart; the bottom surfaces of the multiple longitudinal moving beams 3 are all located in the same plane, and the multiple longitudinal moving beams 3 are arranged in parallel and spaced apart.

[0033] Specifically, if Figure 2 and Figure 3 As shown, the number of transverse beams 2 and longitudinal beams 3 is selected based on the specifications of the components stored in the IC tray. The top surfaces of the multiple transverse beams 2 all lie in the same plane to ensure even and flat placement of the components. The bottom surfaces of the multiple transverse beams 2 are provided with retaining grooves 6 that engage with the mating grooves 7 of the longitudinal beams 3. The mating grooves 7 are located on the top surfaces of the longitudinal beams 3, and the bottom surfaces of the multiple longitudinal beams 3 all lie in the same plane. The parallel spacing of the multiple transverse beams 2 and the multiple longitudinal beams 3 is adjusted based on the specific specifications and number of components stored in the IC tray.

[0034] Preferably, in the embodiment of the present application, the tray support 1 is rectangular, and bosses 4 for limiting are provided on two opposite sides of the tray support 1 .

[0035] It should be noted that if Figure 1 As shown, in the embodiment of the present application, the tray holder 1 is rectangular, with the transverse and longitudinal beams 2 and 3 moving in perpendicular directions. However, in other embodiments, the tray holder 1 can also be diamond-shaped, with the angle between the transverse and longitudinal beams 2 and 3 being a minor angle. Bosses 4 are provided on opposite sides of the tray holder 1 to limit the movement of the IC tray.

[0036] Furthermore, the tray support 1, the transverse moving beam 2 and the longitudinal moving beam 3 are all made of polypropylene plastic.

[0037] Specifically, polypropylene (PP), a commonly used material for IC trays, is a colorless, odorless, non-toxic, translucent solid. It is heat-resistant and anti-static, with an operating temperature range of -30°C to 140°C. This prevents tray deformation caused by high-temperature components during actual production. Alternatively, other heat-resistant and anti-static materials such as MPPO (polyphenylene ether), PPE (polypropylene), and PSU (polysulfone) can be used.

[0038] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
