DETAILED DESCRIPTION

[0024] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the drawings and specific implementation methods of the specification. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] like Figure 1-6 The automatic material tray collecting device shown in the figure comprises a base 1, two guide rails 2 are installed in parallel on the upper side of the base 1, four support seats 4 are symmetrically installed on the two guide rails 2, and support claws 41 are flipably installed on the support seats 4, and the support claws 41 at least partially extend between the two guide rails 2. A lifting mechanism 3 is installed on the base 1, and lifting plates 31 are vertically installed on both sides of the lifting mechanism 3. The lifting plates 31 are parallel to the guide rails 2, and the lifting plates 31 are arranged close to the inner side of the guide rails 2. A conveying mechanism (not shown) is arranged between the two lifting plates 31, and the conveying plane of the conveying mechanism is higher than the top surface of the lifting plate 31 and lower than the top surface of the guide rail 2.

[0026] When in use, the conveying mechanism conveys the material tray 7 to between the two tracks 2, and the lifting mechanism 3 lifts the material tray 7 upward, so that the supporting claw 41 flips upward and resets, and then the lifting mechanism 3 descends to make the material tray 7 fall on the supporting claw 41. Repeat the above actions to stack the material trays 7 one by one, so as to realize the automatic collection of the material trays 7. The lifting mechanism lifts the material trays, and the flipping and resetting of the supporting claws are coordinated to realize the automatic collection of the material trays. The recycling method is simple and efficient, and the investment cost is low.

[0027] like Figure 1 , Figure 4 , Figure 5As shown, two guide rails 2 are horizontally mounted on the upper end surface of the base 1 through brackets (not shown), and a guide groove 21 is provided on the upper surface of the guide rail 2. The guide groove 21 is connected to the inner side surface of the guide rail 2, and a protruding step is formed on the adjacent side of the two guide rails 2. During transportation, both sides of the material tray 7 are accommodated in the guide groove 21, so as to guide and limit the material tray 7.

[0028] like Figure 4 , Figure 5 As shown, four support seats 4 are symmetrically installed at both ends of the two guide rails 2, and steps 42 are provided on the side of the support seats 4. A rotating shaft 43 is horizontally installed on the side wall of the support seat 4 located above the steps 42. A supporting claw 41 is rotatably installed on the rotating shaft 43. One end of the supporting claw 41 extends out of the support seat 4 to between the two guide rails 2, and the center of gravity of the supporting claw 41 is located near the end extending out of the supporting seat 4. In the absence of external force, the end of the supporting claw 41 extending out of the support seat 4 overlaps the step 42 in a horizontal state; when the material tray 7 moves from bottom to top, the supporting claw 41 is pushed to flip upward to provide a position for the upward movement of the material tray 7.

[0029] like Figure 4 As shown, two guide rods 6 are symmetrically installed on the inner side of the two support seats 4 at the left end, and the adjacent sides of the two guide rods 6 are respectively flush with the side walls of the guide groove 21, which are used to guide the rising material tray 7. Two height detection rods 5 are symmetrically installed on the inner side of the two support seats 4 at the right end. The height detection rods 5 are L-shaped structures. The side of the height detection rod 5 parallel to the guide rail 2 is flush with the side of the guide groove 21, which is used to guide the side of the material tray 7. The height detection rod 5 is perpendicular to the side of the guide rail 2 and extends between the two guide rails 2, which is used to limit the lifting position of the material tray 7.

[0030] Preferably, an empty material sensor 51 is installed at the lower end of the height detection rod 5, and a full material sensor 52 is installed at the upper end of the height detection rod 5. Both the empty material sensor 51 and the full material sensor 52 are through-beam photoelectric switches.

[0031] like Figure 1-3 As shown, the lifting mechanism 3 includes a lifting cylinder 32, which is vertically installed at the center of the lower end surface of the base 1. The telescopic rod of the lifting cylinder 32 is fixedly connected to a rectangular lifting platform 33. Guide rods 34 are vertically installed at the four corners of the upper end surface of the lifting platform 33. The guide rods 34 are connected to the base 1 through linear bearings. The top of the guide rods 34 passes through the base 1, and the two lifting plates 31 are respectively fixed to the tops of the two guide rods 34.

[0032] like Figure 3As shown, a trigger plate 35 is vertically installed on the upper side of the jacking platform 33, the right side of the top of the trigger plate 35 protrudes to form an upper trigger part 351, and the lower part of the left side of the trigger plate 35 protrudes to form a lower trigger part 352. An upper limit sensor 36 and a lower limit sensor 37 are fixed to the lower side of the base 1 through brackets, and the upper limit sensor 36 and the lower limit sensor 37 cooperate with the upper trigger part 351 and the lower trigger part 352 to realize the positioning of the upper and lower positions of the jacking cylinder 32.

[0033] Preferably, a buffer pad is installed between the telescopic rod of the jacking cylinder 32 and the jacking platform 33 to reduce the impact between the jacking plate 31 and the material tray 7, avoid damage to the material tray 7, and extend the service life of the jacking cylinder 32.

[0034] Preferably, the conveying mechanism is a double belt streamline, and the conveying plane of the double belt streamline is higher than the height of the top surface of the lifting plate 31 and lower than the bottom surface of the guide groove 21. Figure 2 As shown, a position sensor 8 is installed at one end of the height detection rod 5 on the base 1. The position sensor 8 is located between the two conveyor belts of the double-belt streamline and is used to detect whether there is a material tray 7 at the jacking position. When the position sensor 8 detects the presence of a material tray, the jacking cylinder 32 performs a jacking action.

[0035] like Figure 1-Figure 6 As shown, the working principle of the embodiment of the present application is:

[0036] The conveying mechanism conveys the material tray 7 between the two guide rails 2. The guide groove 21 between the guide rails 2 is used to guide the material tray 7. When the material tray 7 abuts against the height detection rod 5, it stops moving. At this time, the position sensor 8 detects the material tray 7, and the lifting mechanism 3 drives the lifting plate 31 to rise, thereby lifting the material tray 7 upward.

[0037] During the upward movement of the tray 7, the support claws 41 are pushed upward. When the tray 7 completely passes through the support claws 41, the support claws 41 return to a horizontal state under the action of gravity. The lifting mechanism 3 drives the lifting plate 31 to reset downward, and the tray 7 falls on the four support claws 41. Repeat the above actions to achieve the stacking and collection of multiple trays 7. When the stacking height of the trays 7 triggers the full material sensor 52, the entire device stops running, prompts the operator to move out the tray 7, and starts the automatic collection of the tray 7 after resetting.

[0038] By lifting the edge of the tray 7 through two lifting plates 31, the tray can be prevented from tipping over and deviating during the lifting process; the cooperation between the guide rod 6 and the height detection rod 5 can also achieve position limiting during the stacking process of the trays to prevent the trays from tipping over.

[0039] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present utility model: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0040] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
