[0026] The utility model is further described below in conjunction with embodiments and drawings.
[0027] like Figure 1As shown, an automatic switching device for material trays includes a conveying component A, and an empty tray recovery mechanism B, a full tray placement mechanism C, and a clamping claw connection mechanism D are sequentially installed in the conveying direction of the conveying component A. Among them, the empty tray recovery mechanism B can stack the empty trays in a vertical stacking manner, the full tray placement mechanism C can stack the full trays in a vertical stacking manner, and the clamping claw connection mechanism D is used to stably support the full trays. In specific applications, the clamping claw connection mechanism D is arranged at a position close to the mechanical clamp, and the mechanical clamp can take and place the tail cover parts on the full tray from this area. Under the action of the conveying component A and the full tray placement mechanism C, the full tray stacked on the bottom layer of the full tray placement mechanism C can be transported to the clamping claw connection mechanism D. Under the action of the conveying component A and the empty tray recovery mechanism B, the empty tray located on the clamping claw connection mechanism D can be transported and stacked on the bottom layer of the empty tray recovery mechanism B.
[0028] With such a design, through the interaction between the transmission component A and the empty tray recovery mechanism B and the clamp connection mechanism D, automatic switching between the empty tray and the full tray at the clamp connection mechanism D can be achieved, with a high degree of automation, fast switching efficiency, and reduced labor costs.
[0029] For details, please refer to Figure 2 The conveying assembly A includes a mounting plate 1 that is symmetrically distributed on both sides. A conveying crawler 2 is installed on the top of the inner side of the two mounting plates 1. The top of the conveying crawler 2 is used to place the material tray. A synchronous rod 3 is arranged between the two sets of conveying crawlers 2. A driving motor 4 is also fixedly installed between the two mounting plates 1. The driving motor 4 is used to drive the synchronous rod 3 to rotate. In this embodiment, an output wheel 16 is sleeved on the output end of the driving motor 4, and a synchronous wheel 17 is sleeved on the synchronous rod 3. The output wheel 16 and the synchronous wheel 17 are connected by a synchronous belt 18. With such a design, the conveying crawler 2 can be rotated by running the driving motor 4, thereby ensuring the transportation of the material tray.
[0030] like Figure 3 As shown, the empty tray recovery mechanism B includes first pillars 5 symmetrically arranged on the upper outer sides of two mounting uprights 1, and a first lifting cylinder 6 arranged between the two mounting uprights 1. In this embodiment, two first pillars 5 are fixedly installed on any mounting upright 1, and four first pillars 5 are symmetrically distributed in pairs to form a rectangular frame, and the rectangular frame is used to stack empty trays vertically. A support block 7 is arranged on one side of each first pillar 5 close to the conveyor crawler 2, and the empty tray lifted by the first lifting cylinder 6 can be supported by the support block 7.
[0031] like Figure 3 and Figure 6As shown, in this embodiment, a protrusion 7a is rotatably provided on one side of the support block 7 close to the conveyor track 2, and the top of the protrusion 7a is used to support the empty tray. The empty tray lifted by the first lifting cylinder 6 can force each protrusion 7a to rotate toward the outside of the mounting plate 1. A reset element 7b is connected between the support block 7 and the protrusion 7a, and the reset element 7b applies a reset force that ensures the protrusion 7a to be in a protruding state, that is, when the first lifting cylinder 6 lifts the empty tray beyond the upper end surface of the protrusion 7a, the reset element 7b forces the protrusion 7a to rotate to a protruding state, so that the top of the protrusion 7a can be used to support the empty tray. With such a design, the entire empty tray recovery mechanism B is made more compact by the method of longitudinal stacking, and the rotating protrusion 7a also makes the entire support structure very compact. In order to facilitate the rotation of the protrusion 7a, a guiding inclined surface 7c is also formed at the lower end of the protrusion 7a.
[0032] In this embodiment, the empty trays stacked at the empty tray recovery mechanism B are ultimately transported manually. In order to prevent the empty tray recovery mechanism B from collapsing due to excessive empty trays stacked thereon, a limiting photoelectric 19 is further provided at the upper end of the first pillar 5.
[0033] For example Figure 4 As shown, the full tray placement mechanism C includes a clamping mechanism E symmetrically arranged on the outside of two mounting plates 1, a second pillar 8, and a second lifting cylinder 9 fixedly installed between the two mounting plates 1 by bolts, wherein two second pillars 8 are installed on any mounting plate 1, and the two second pillars 8 are symmetrically distributed on the left and right sides of the clamping mechanism E, and the four second pillars 8 are symmetrically distributed in pairs to form a rectangular frame, and full trays can be conveniently stacked in the rectangular frame, and the clamping assembly E is used to clamp the full trays.
[0034] In this embodiment, the clamping mechanism E includes a fourth lifting cylinder 12 fixedly installed on the outside of the mounting plate 1 and a clamping cylinder 13 fixedly installed on the top of the fourth lifting cylinder 12, wherein the fourth fixed lifting cylinder 12 is directly used to lift the clamping cylinder 13 up and down, and the clamping cylinder 13 is used to clamp the full material tray.
[0035] Under normal conditions, the fourth lifting cylinder 12 is in a retracted state and the clamping cylinder 13 is in a clamping state. When the full tray needs to be placed on the conveyor belt 2, the second lifting cylinder 9 is lifted and ensures that the plane where the top of the second lifting cylinder 9 is located exceeds the upper end surface of the conveyor belt 2; then the clamping cylinder 13 is released, and the stacked full trays fall to the top of the second lifting cylinder 9; then the fourth lifting cylinder 12 drives the clamping cylinder 13 to lift to the position of the second layer of full trays and clamp to ensure that only one full tray is placed on the top of the second lifting cylinder 9; finally, the second lifting cylinder 9 contracts so that the full tray is placed on the conveyor belt 2.
[0036] like Figure 5As shown, the clamp connection mechanism D includes a third lifting cylinder 10 arranged between two mounting plates 1, and a support block 11 fixedly installed on the top of the two mounting plates 1. The material tray lifted by the third lifting cylinder 10 can rest against the lower end of the support plate 11 to ensure that the material tray will not shake when the mechanical clamp grabs the tail cover.
[0037] In this embodiment, the ends of the two mounting uprights 1 are fixed with limit plates 14 by bolts, and the limit plates 14 can effectively prevent the conveyor track 2 from not stopping in time and causing the tray to fall. A sensing element 15 is arranged in the middle of the limit plate 14, and the sensing element 15 can sense whether the tray moves to the empty tray recovery mechanism B and the clamping claw connection mechanism D. In addition, in this embodiment, a sensing element 15 is also installed on the second lifting cylinder 9 to detect whether the tray moves to the full tray placement mechanism C.
[0038] In this embodiment, the cross-sections of the first pillars 5 and the second pillars 8 are both "L"-shaped structures, so that the rectangular structure formed by the four first pillars 5 and the rectangular structure formed by the four second pillars 8 are easier to stack the trays, and the trays are not prone to displacement and tipping.
[0039] In order to facilitate the first lifting cylinder 6, the second lifting cylinder 9 and the third lifting cylinder 10 to lift the material tray more stably, in this embodiment, a base plate 20 is fixedly installed on the ends of the cylinder rods of the first lifting cylinder 6, the second lifting cylinder 9 and the third lifting cylinder 10 by bolts.
[0040] In this embodiment, the driving motor 4 is also connected to a speed regulator 21 , and the speed regulator 21 can control the speed at which the conveying track 2 conveys the material tray.
[0041] Through the above structure, the working process of the automatic tray switching device is as follows:
[0042] When the tray at the clamping claw connection mechanism D needs to be replaced, the third lifting cylinder 10 descends, causing the empty tray to fall onto the conveyor track 2, and the driving motor 4 drives the conveyor track 2 to rotate, so that the empty tray moves to the empty tray recovery mechanism B. At the same time, the sensing element 15 senses whether the tray is in place, and the limit plate 14 prevents the empty tray from falling; then the first lifting cylinder 6 is lifted, so that the empty tray moves upward and is finally supported on the top of the protrusion 7a; then, the first lifting cylinder 6 is lowered, and the second lifting cylinder 9 is lifted, clamping The cylinder 13 is released, so that the stacked full trays fall to the top of the second lifting cylinder 9; then, the fourth lifting cylinder 12 is lifted, and the clamping cylinder 13 is clamped again to ensure that only one full tray falls to the top of the second lifting cylinder 9; then, the second lifting cylinder 9 descends, so that the full tray falls to the conveyor track 2; then, the drive motor 4 is reversed, so that the full tray is conveyed to the clamping claw connection mechanism D; finally, the third lifting cylinder 10 is lifted, so that the full tray rests on the lower end of the support plate 11, completing the replacement of the entire tray.
[0043] With such a design, the entire tray replacement process, except for stacking full trays on the full tray placement mechanism C and recovering empty trays from the empty tray recovery mechanism B, is an automated operation, which not only ensures the tray replacement efficiency but also greatly reduces labor costs.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make a variety of similar expressions without violating the purpose and claims of the present invention, and such changes fall within the scope of protection of the present invention.
