DETAILED DESCRIPTION

[0021] In order to explain the present invention more clearly, the present invention is further described below in conjunction with preferred embodiments. Those skilled in the art should understand that the following specific description is illustrative rather than restrictive, and should not be used to limit the scope of protection of the present invention.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0023] See also Figure 1 and Figure 2 The utility model embodiment proposes a tray separation mechanism, including a tray bin, which is open at the upper and lower ends, and is used to stack a number of trays; a transverse guide rail 2 is arranged on the back of the tray bin, and two symmetrical displacement plates 3 are respectively arranged on the guide rail 2 in a sliding and clamping manner through sliders, that is, the displacement plates 3 can move horizontally, and a tension spring 4 is connected between the upper ends of the two displacement plates 3, and the tension spring 4 is always in a tensioned state, that is, under the action of the tension spring 4, the two displacement plates 3 will always be Move closer to the middle; a clamping baffle 6 is vertically arranged at the lower part of the displacement plate 3 and is located on one side of the bottom of the material tray bin, and a dividing tray insertion strip 61 is provided at the bottom end of the clamping baffle 6 which protrudes inward and extends. The clamping baffles 6 on both sides are respectively located on the sides of the stacked material trays in the material tray bin, and under the action of the tension spring 4, the clamping baffle 6 will move closer to the middle together with the displacement plate 3 until the clamping baffle 6 contacts the side of the material tray. At this time, the dividing tray insertion strip 61 at the bottom end of the clamping baffle 6 will be at the bottom of the material tray, thereby supporting the stacked material trays in the material tray bin.

[0024] Secondly, a lifting cylinder 5 is also provided on the back of the material tray bin, and the output end of the lifting cylinder 5 is upwardly connected to a lifting cone 51 located on the central symmetry line between the two displacement plates 3. The two displacement plates 3 are opened by the lifting cone 51. The diameter of the lifting cone 51 is a gradient design with a narrow upper part and a wide lower part. That is to say, the lifting cone 51 is driven by the lifting cylinder 5 to move upward, so that the lifting cone 51 is inserted upward between the two displacement plates 3, so as to prop up the two displacement plates 3 outward, thereby realizing the outward translation movement of the clamping baffle 6.

[0025] When the tray dividing mechanism is in use, it is used in conjunction with an external lifting platform, that is, the lifting platform moves to the bottom of the tray bin, and then the lifting cylinder drives the lifting cone to open the two displacement plates outward, so as to realize the outward translation of the clamping baffles on both sides, so that the tray dividing strip is pulled out from the bottom of the tray. At this time, the stacked trays in the tray bin will fall downward on the lifting platform, and then the lifting cylinder drives the lifting cone to move downward. Under the stretching action of the tension spring, the two displacement plates will gradually move toward the middle, so as to realize the inward translation of the clamping baffles on both sides, so that the tray dividing strip is inserted between the penultimate tray and the penultimate tray, realizing the tray dividing action of the penultimate tray, and the separated tray is moved to the next workstation by the lifting platform; then the above process is repeated to separate and unload the trays stacked together in the tray bin one by one.

[0026] Specifically, a rotatable contact roller 31 is disposed on the inner side of the displacement plate 3, a spacing is left between the contact rollers 31 on the two displacement plates 3, and the lifting cone 51 is located on the central symmetry line between the two contact rollers 31. In this way, when the lifting cylinder drives the lifting cone to move upward, the lifting cone will squeeze between the two contact rollers from bottom to top, and there will be rolling friction between the contact rollers, reducing the friction force, thereby realizing the rapid outward expansion of the two displacement plates.

[0027] Specifically, two left and right slot-type photoelectric switches 32 are symmetrically arranged on the back of the material tray bin, and contact pieces 33 that can be used to trigger the slot-type photoelectric switches 32 are respectively arranged on the two displacement plates 3. When the contact pieces trigger the slot-type photoelectric switches, it means that the clamping baffle has been translated into place and the lifting cylinder has stopped moving.

[0028] Specifically, the material tray bin includes a vertical plate 1, vertical side plates 11 are symmetrically arranged on both sides of the vertical plate 1, the lower part of the side plate 11 extends forward to form a support plate 12, and the front end of the support plate 12 is bent inward to form a limiting retaining edge 13. In this way, a rectangular space for stacking a number of material trays is formed by the side plates, the support plates, and the limiting retaining edges, thereby making rational use of the space.

[0029] Among them, a gap 121 is set at the lower part of the support plate 12 for the clamping baffle 6 to pass through, so that the clamping baffle can translate through the gap and contact or separate from the side of the material tray in the material tray bin.

[0030] Among them, the top end of the limiting retaining edge 13 is inclined outward to set a protective part 131. When the number of stacked trays in the tray bin is large and the overall height is high, the protective part can play a blocking effect to a certain extent to prevent the stacked trays from excessively moving outward during the downward movement.

[0031] On the basis of the above embodiments, further, Figure 3As shown, the utility model also provides a tray dividing device, including two spaced-apart parallel supporting legs 20, a crossbeam 30 is commonly arranged between the top ends of the two supporting legs 20, and a plurality of tray dividing mechanisms 10 as described above are arranged in a horizontal array on the crossbeam 30, so as to realize batch tray dividing of multiple groups of material tray bins and improve work efficiency.

[0032] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
