Description

Technical Field

[0001] The invention relates to the field of automatic loading and unloading of electronic materials, and in particular to a silo and a silo mechanism. Background Art

[0002] refer to Figure 1 , the automatic loading and unloading of electronic materials cannot be separated from the tray. The tray 5 is used to hold electronic materials to facilitate the automatic transportation of electronic materials. Generally, the upper surface of the tray 5 is provided with pits 51 distributed in an array for placing electronic materials. A plurality of bayonet holes 52 are provided at the bottom of a pair of sides of the tray 5. Preferably, two bayonet holes 52 are provided on one side. The electronic materials on the tray 5 can be fixed by covering the tray cover plate on the tray 5 to prevent the electronic materials from escaping from the pit 51. However, since the electronic materials, especially the chip materials, are getting smaller and lighter in volume, the tray cover plate and the tray are well covered during the transportation and transfer of the existing tray 5, resulting in the electronic materials being easily detached from the pit 51 during the movement of the tray, resulting in the electronic materials in the tray being dislocated, jumping, etc. In addition, electronic materials such as chip materials are light and small. During the transportation and transfer of the tray 5, due to the unstable lifting and moving process, it is also easy for the electronic materials to be easily detached from the pit 51, resulting in the electronic materials in the tray being dislocated / jumping, resulting in the inability to load and unload. Rearranging the chips in the tray requires a lot of manpower and time, which seriously affects the loading and unloading efficiency of chips and other electronic materials.

[0003] In addition, the existing silo used for loading and unloading the material tray 5 can only store material trays with one function. When material trays with different functions need to be added, additional silos need to be added to achieve this. That is, one silo cannot realize the loading and unloading of material trays with different functions. The silos are not versatile, and the silos cannot be switched at any time. Moreover, the solution of implementing multiple silos requires a large equipment space. Summary of the invention

[0024] refer to Figure 4 and5 In a preferred embodiment, the silo mechanism includes a silo 1, an X-axis tray-taking mechanism 2, a Z-axis lifting mechanism 3 and a cylinder assembly 4. The Z-axis lifting mechanism 3 is used to drive the overall lifting of the silo 1, and the X-axis tray-taking mechanism 2 is used to enter the interior of the silo 1, take the tray in the silo 1 and move the tray horizontally out of the silo 1. The X-axis tray-taking mechanism 2 has an X-axis moving support plate 21, and the X-axis tray-taking mechanism 2 extends into the interior of the silo 1 through the X-axis moving support plate 21 to take the tray and move it out of the silo 1. The cylinder assembly 4 is provided with a tray buckle 41, and the cylinder assembly 4 is used to control the tray buckle 41 to extend to support the tray cover plate to separate the tray and the tray cover plate (or extend into the tray bayonet when the upper and lower trays are stacked to separate the upper and lower trays), or control the tray buckle 41 to retract to allow the silo 1 and the tray to be lifted up and down.

[0025] refer to Figure 2 and 3 The silo 1 includes a bottom plate 12, two side plates 11 (i.e., a left plate and a right plate) arranged in parallel on the left and right sides of the bottom plate 12, and a top plate 13. The bottom plate 12, the side plates 11 and the top plate 13 surround a silo space for accommodating the material tray. The inner walls of the two side plates 11 are provided with a plurality of groups of tray raised strips 14 at intervals in the Z-axis direction. Each group of tray raised strips 14 has two tray raised strips 14, and the two tray raised strips 14 have the same height in the Z-axis, extend along the X-axis and are relatively raised in the Y-axis direction, that is, the two tray raised strips 14 are horizontally mirrored on the inner walls of the two side plates 11. Each group of tray raised strips 14 is used to hold the material tray from the bottom edge. The silo space is divided into a corresponding number of sub-material cavities 18 by the plurality of groups of tray raised strips 14. Figure 2 In the middle, it is divided into 4 sub-cavities 18. The sub-cavities 18 are distributed up and down along the Z axis. Each sub-cavity 18 stores a number of trays. Each sub-cavity 18 can hold trays with the same function or trays with different functions. Above each group of tray protrusions 14, a number of tray pressing blocks 15 are provided on the inner wall of the side plate 11. Preferably, the tray pressing blocks 15 are circular and are elastic, such as urethane. In this way, each sub-cavity 18 can store a number of trays separately, and the tray protrusions 14 support the trays from the bottom edge, while the tray pressing blocks 15 press the tray cover plate of the top layer of each sub-cavity 18. In this way, during the overall lifting of the silo 1, or the material taking process of the X-axis tray taking mechanism 2, the trays are stacked, or the tray cover plate and the tray are pressed against each other, which can avoid the shaking of the trays and prevent the internal electronic materials from jumping out, falling or misalignment. In addition, since the tray pressing block 15 is round and elastic, it is also beneficial to push the tray into the silo, reducing resistance and ensuring that the tray cover always presses the tray tightly during the pushing process.

[0026] In a preferred embodiment, a plurality of connecting rods 16 are provided between the two side panels 11, i.e., the inner walls of the left and right panels. The connecting rods 16 are located below each group of tray protrusion strips 14, and the distance between the connecting rods 16 and the tray protrusion strips 14 in the Z axis is ≥ the thickness of the X-axis movable pallet 21. In this way, a material taking cavity 19 is formed between the connecting rods 16 and the tray protrusion strips 14 for the horizontal entry and exit of the X-axis movable pallet 21. Preferably, the lowest point of each tray pressing block 15 is located below the corresponding connecting rod 16. In this way, when each sub-cavity 18 stores a tray, the tray will not occupy the space of the material taking cavity 19, and will not affect the horizontal entry and exit of the X-axis movable pallet 21. Since a material taking cavity 19 is provided between each sub-cavity 18, it is ensured that the X-axis movable pallet 21 can enter the bottom of each sub-cavity 18 tray to perform the tray taking and transfer operations. In this way, each sub-cavity 18 can be defined as a different bin or bin mode as needed, and trays with different functions can be placed in each sub-cavity 18. For example, one of the sub-material chambers 18 can be defined as the first re-measurement position, one as the second re-measurement position, one as the spare position, one as the default loading and unloading position, one as the cleaning disk position, and so on. In this way, a silo can realize different working modes or different functions, realize the multi-function of the silo, enhance the versatility of the silo, and reduce the equipment space occupied by the silo.

[0027] refer to Figure 2 and 3 In a preferred embodiment, no connecting rod 16 is provided below the lowest sub-material cavity 18, but the distance between the bottom plate 12 and the lowest sub-material cavity 18 in the Z-axis is ≥ the thickness of the X-axis movable pallet 21, so that the bottom plate 12 and the lowest sub-material cavity 18 can also form a material taking cavity 19 to ensure the horizontal entry and exit of the X-axis movable pallet 21.

[0028] In a preferred embodiment, a tray limiting rod 17 is provided between the bottom plate 12 and the top plate 13 at the other end away from the silo entrance (the silo entrance refers to the end where the connecting rod 16 is located or the end of the support plate 21 moving toward the X-axis). When the tray is pushed in, the tray is put into place when it abuts against the tray limiting rod 17. In addition, it can also prevent the tray from horizontally detaching from the silo during the overall lifting process of the silo 1 to a certain extent.

[0029] Continue to refer Figure 4 and 5In a preferred embodiment, the X-axis material picking tray mechanism 2 includes a horizontally arranged guide rail, a driving motor, a belt, a slider, etc. The X-axis movable support plate 21 is fixedly connected to the slider, and the driving motor drives the slider to move along the guide rail through the belt, thereby realizing the movement of the X-axis movable support plate 21 along the X-axis. Similarly, the Z-axis lifting mechanism 3 includes a driving motor, a screw, a screw nut connecting seat 31, a lifting assembly 32, etc. The lifting assembly 32 is fixedly connected to the screw nut connecting seat 31. The Z-axis lifting mechanism 3 drives the screw to rotate through the driving motor, and the rotation of the screw drives the screw nut connecting seat 31 to rise and fall, thereby driving the lifting assembly 32 to move up and down. Preferably, the lifting assembly 32 includes a horizontally arranged lifting plate or support frame, and a reinforcing rib 321. The lifting plate or support frame is fixedly connected to the screw nut connecting seat 31 through the reinforcing rib 321. A clip 322 is also provided on the lifting plate or the support frame. When the silo 1 is placed on the lifting plate or the support frame as a whole, both sides of the silo 1 are automatically clamped and fixed to prevent the silo 1 from shaking or deflecting during the lifting process, and also facilitate the replacement of the silo 1.

[0030] In this way, the entire silo 1 can be lifted and lowered smoothly through the Z-axis lifting mechanism 3, so that different material removal cavities 19 are at the same height as the X-axis movable pallet 21, so as to facilitate the X-axis movable pallet 21 to remove and move the material tray of the corresponding sub-cavity 18, and also facilitate the operation of material trays at different heights.

[0031] When the silo mechanism is working, first, the silo 1 is placed on the lifting plate or support frame of the lifting assembly 32, and the spring clip 322 of the lifting assembly 32 automatically clamps the two sides of the silo 1. The Z-axis lifting mechanism 3 drives the silo 1 to lift as a whole, so that the sub-cavity 18 corresponding to the tray to be taken reaches the specified height, specifically, the material taking cavity 19 below the sub-cavity 18 is at the same height as the X-axis moving support plate 21 of the X-axis material taking tray mechanism 2, or the bottom of the tray at the bottom of the sub-cavity 18 reaches the height of the tray to be taken that matches the X-axis moving support plate 21. The X-axis moving support plate 21 of the X-axis material taking tray mechanism 2 moves along the X-axis, enters the material taking cavity 19 and reaches directly below the tray to be taken in the corresponding sub-cavity 18. The cylinder assembly 4 drives the tray buckle 41 to extend to support the tray cover, and the Z-axis lifting mechanism 3 drives the silo 1 to lift as a whole, so that the tray and the tray cover are separated. Finally, the X-axis moving support plate 21 moves along the X-axis to move the tray out of the silo. In this way, each sub-cavity 18 of the silo 1 can be defined as a different bin or bin mode to place trays with different functions. When a specific tray needs to be operated, the cooperation of the Z-axis lifting mechanism 3 and the X-axis tray-taking mechanism 2, as well as the unique structure of the silo, can smoothly, quickly and accurately operate the required tray, realizing the multi-function of the silo 1, enhancing its versatility, and avoiding the shaking of the tray, preventing the internal electronic materials from jumping out, falling or misalignment.
