[0002] In the field of surface mount technology for electronic components, SMT trays are important tools for carrying and transporting SMT bulk components, and their performance directly affects the efficiency and quality of electronic component placement.
[0003] Existing technologies, such as the SMT tray disclosed in patent CN220182110U, have certain shortcomings in practical use. The main problem with these existing trays is low loading efficiency. Their load-bearing structure is usually fixed, making it impossible to adjust their position according to the specifications of loose SMT components, the gripping angle of robot fixtures, or production process requirements. This results in low efficiency, cumbersome operation, and time-consuming loading each time. It is difficult to meet the demands of modern large-scale production for efficient loading.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] refer to Figure 1-4 This embodiment of an SMT tray includes a tray body 1 and a servo motor 4. A fixing block is fixedly disposed in the center of the tray body 1, and the servo motor 4 is installed below the fixing block. The shaft of the servo motor 4 is connected to the fixing block by a thread to ensure stability during rotation. Four arc-shaped through holes 3 are evenly distributed around the center of the tray body 1, and each arc-shaped through hole 3 is equipped with a mounting component 2 for supporting the SMT loose material shell 202. A circular base 6 is disposed at the bottom of the servo motor 4, and a second tray body 7 is connected below it. The bottom of the second tray body 7 is fixed to the shaft of a rotary motor 8, and a second base 9 is installed below the rotary motor 8, forming a multi-layer rotating structure.
[0023] Mounting assembly 2 includes a support base 205, a circular pin 204, and a movable plate 201. The support base 205 has a through-hole in the square shape, and the movable plate 201 passes through the through-hole and is slidably connected to the support base 205. A circular through-hole is formed at one end of the movable plate 201 near the fixed block, through which the circular pin 204 passes and is fitted into the arc-shaped through-hole 3, allowing the movable plate 201 to move along an arc-shaped trajectory. Multiple sets of SMT loose component housings 202 are provided at the other end of the movable plate 201 for storing loose SMT components. Multiple limiting grooves are formed above the square through-hole of the support base 205, and corresponding discharge devices 203 are provided above them to achieve automatic loading and locking of loose components.
[0024] The support base 205 is fixedly connected to the tray body 2 7 via a support column 701, which enhances the structural stability of the mounting assembly 2. A circular groove is provided in the center of the top surface of the tray body 2 7, which is fixed to the circular base 1 6 with an embedded thread. A circular ring column is fixed at the bottom and connected to the shaft of the rotary motor 8, ensuring that the tray body 2 7 can rotate synchronously with the rotary motor 8.
[0025] In some examples, a circular bearing 207 is fitted on the circular pin 204. The circular bearing 207 is clearance-fitted with the arc-shaped through hole 3 to reduce the frictional resistance when the moving plate 201 slides, so that the displacement of the moving plate 201 is smoother when the pallet body 1 rotates, and the stability of the automatic feeding process is improved.
[0026] In some examples, the dispensing device 203 includes a square frame, a spring 209, and a baffle 211. A pivot 208 is fixed at each of the four corners of the square frame, and a baffle 211 is mounted on the pivot 208. A strong magnet 210 passes through the center of the baffle 211, and the bottom end of the baffle 211 is connected to the side wall of the square frame via the spring 209. The spring 209 supports the baffle 211 to maintain a horizontal position. When workers temporarily retrieve components, the strong magnet 210 can attract loose SMT components, preventing them from falling and facilitating accurate component retrieval.
[0027] In some examples, the SMT bulk material shell 202 and the limiting groove of the support base 205 are embedded. The protrusions on both sides of the shell and the grooves on both sides of the limiting groove are fitted together to ensure that when the SMT bulk material shell 202 reaches the designated position under the action of the moving plate 201, it can be accurately locked into the limiting groove, thereby achieving automatic locking and preventing the bulk material shell from shaking and affecting the loading accuracy.
[0028] In some examples, a circular groove is opened in the center of the top of the base 2 9, and the rotary motor 8 is fixed in the groove. This structure enhances the stability of the rotary motor 8 through embedded installation, reduces vibration during operation, and makes the rotation angle of the tray body 2 7 more precise, which makes it easier for the robot mechanical fixture to accurately pick up SMT bulk materials.
[0029] In some examples, the top of the support column 701 is fixed to the support base 205, and the bottom is fixed to the pallet body 2 7 by bolts. This connection method facilitates disassembly and maintenance, while enhancing the support strength of the support column 701 for the mounting component 2, ensuring that the mounting component 2 will not tilt due to uneven force when the pallet body 1 rotates.
[0030] The working principle of this utility model is as follows:
[0031] When using this SMT tray, the operator first loads the loose SMT components into the SMT component housing 202 at the other end of the moving plate 201, completing the initial placement of the components. Then, the servo motor 4 is activated. The shaft of the servo motor 4 is threadedly fixed to the fixing block in the center of the tray body 1, thereby causing the tray body 1 to rotate counterclockwise. Since the tray body 1 has four arc-shaped through holes 3 around its center, and the circular pin 204 in the mounting assembly 2 passes through the circular through holes of the moving plate 201 and is fitted into the arc-shaped through holes 3, as the tray body 1 rotates, the circular pin 204 moves inward along the arc-shaped through holes 3, thereby causing the moving plate 201 to slide within the square through hole of the support base 205, thus moving the moving plate 201 inward.
[0032] When the moving board 201 reaches a specific position, the SMT bulk material shell 202 and the limiting groove on the support base 205 are embedded and engaged. The protrusions on both sides of the SMT bulk material shell 202 and the grooves on both sides of the limiting groove are engaged with the gap, thereby quickly and stably completing the loading and locking process of the SMT bulk material, ensuring that the bulk material remains stable in subsequent processes.
[0033] When it is necessary to replace loose materials later, the rotary motor 8 under the tray body 2 7 is activated. Since the circular column at the bottom of the tray body 2 7 is fixedly connected to the shaft of the rotary motor 8, the rotary motor 8 drives the tray body 2 7 to rotate. The support base 205 is fixedly connected to the tray body 2 7 through the support column 701, thereby realizing the rotation of the SMT loose material shell 202. This rotation function can well adapt to the picking angle and position requirements of the robot mechanical fixture, improving the compatibility of the tray with automated equipment.
[0034] In addition, the circular bearing 207 fitted on the circular pin 204 and the arc through hole 3 are fitted with a clearance, which reduces the frictional resistance when the moving plate 201 slides, making the entire movement process smoother. In the material discharge device 203, the spring 209 supports the baffle 211 to be horizontal. When the staff temporarily picks up the SMT loose materials, the strong magnet 210 can temporarily fix the SMT loose materials on the bottom surface of the baffle 211 to prevent the loose materials from falling and facilitate accurate material picking. The circular groove in the center of the top of the base 2 9 fixes the rotary motor 8, which enhances the stability of the rotary motor 8 and ensures that the rotation angle of the tray body 2 7 is accurate, further improving the automation level and production efficiency of the entire production process.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
