Description

Technical Field

[0001] The present invention relates to the technical field of feeding equipment, and in particular to a flipping feeding equipment. Background Art

[0002] Generally, the states of many workpieces such as lenses when coming in are as follows: a plurality of workpieces are pasted on a large film in a way of 12×8 or other specifications.

[0065] In order to make the objectives, features, and advantages of the present invention more obvious and understandable, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0066] In the description of the present invention, it should be understood that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component present at the same time. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component present at the same time.

[0067] In addition, terms such as "long", "short", "inner", "outer", etc. indicating orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or component referred to must have this specific orientation and be constructed and operated in this specific orientation. Therefore, it should not be construed as a limitation of the present invention.

[0068] The following will describe the present invention in detail in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional transformation made by those of ordinary skill in the art based on these embodiments is included in the protection scope of the present invention.

[0069] The present invention provides a flipping feeding device, which is applicable to the application scenario of tearing a workpiece originally facing down from a film and finally recycling it in an upright manner. The flipping feeding device provided by the present invention can realize the mechanized flipping operation of the workpiece, thereby improving production efficiency.

[0070] See Figure 1 , in this embodiment, the flipping feeding device includes a first feeding mechanism 1, a first feeding device 2, a first collecting mechanism 3, a second feeding mechanism 4, a second feeding device 5, a second collecting mechanism 6, a transfer mechanism 7, a third feeding mechanism 8, and a flipping mechanism 9.

[0071] Specifically, the first feeding mechanism 1 is used to store the first trays full of workpieces; the first feeding device 2 is used to convey the first trays; the first collecting mechanism 3 is used to store the empty first trays; the second feeding mechanism 4 is used to store the empty second trays; the second feeding device 5 is used to convey the second trays; the second collecting mechanism 6 is used to store the second trays full of workpieces; the transfer mechanism 7 is used to transfer the workpieces in the first tray located on the first feeding device 2 to the second tray located on the second feeding device 5; the third feeding mechanism 8 is used to provide transfer trays; the flipping mechanism 9 is used to invert the transfer tray onto the second tray and flip the transfer tray and the second tray up and down.

[0072] It should be noted that the flipping feeding device provided in this embodiment works as follows:

[0073] S10: At the beginning, each first tray is placed with a large film, and several workpieces are attached to the film (at this time, the back of the workpieces is facing up). Each of the first trays is stacked and placed in the first feeding mechanism 1, and the first feeding mechanism 1 sends the first trays into the first feeding device 2 one by one;

[0074] Correspondingly, each second tray is provided with several workpiece placing grooves. Each of the second trays is stacked and placed in the second feeding mechanism 4, and the second feeding mechanism 4 sends the second trays into the second feeding device 5 one by one;

[0075] The shape and size of the transfer tray are the same as those of the second tray, that is, the transfer tray is also provided with several workpiece placing grooves corresponding one by one to the workpiece placing grooves of the second tray;

[0076] S20: When the first tray moves to the transfer mechanism 7, the transfer mechanism 7 sucks up the workpieces in the first tray (the film remains on the tray, so the film tearing operation is synchronously completed), and then places the workpieces into the workpiece placing grooves of the second tray. At this time, the workpieces in the second tray are still facing up on the back;

[0077] S30: When the first tray is emptied, the first feeding device 2 sends the empty first tray into the first collecting mechanism 3, and the first collecting mechanism 3 lifts the first tray, so that the empty first trays are stored in a stacked manner in the first collecting mechanism 3;

[0078] S40: When the second tray is full, the second feeding device 5 sends the full second tray to the lower part of the flipping mechanism 9; the flipping mechanism 9 first picks up a transfer tray from the third feeding mechanism 8, and then flips the transfer tray up and down, that is, makes the workpiece placing grooves of the transfer tray face down;

[0079] S50: The flipping mechanism 9 transfers the transfer tray to directly above the full second tray, aligns the transfer tray and the second tray, and then releases the transfer tray;

[0080] S60: The flipping mechanism 9 simultaneously clamps the second tray and the transfer tray, and then flips the second tray and the transfer tray up and down. The workpieces in the second tray will fall into the transfer tray and be in a state with the front side facing up. At this time, the original second tray is replaced by a new transfer tray for the next snap-fit use, and the original transfer tray is replaced by a new fully loaded second tray.

[0081] S70: The flipping mechanism 9 places the second tray back onto the second feeding device 5.

[0082] S80: The second feeding device 5 feeds the fully loaded second tray into the second receiving mechanism 6, and the second receiving mechanism 6 jacks up the second tray, so that the fully loaded second trays are stored in a stacked manner in the second receiving mechanism 6.

[0083] It should be noted that the feeding or receiving mechanisms for storing stacked trays are relatively common, and their specific structures are not the focus of this embodiment. Therefore, this embodiment does not elaborate on the first feeding mechanism 1, the first receiving mechanism 3, the second feeding mechanism 4, the second receiving mechanism 6, etc.

[0084] Furthermore, the first feeding device 2 and the second feeding device 5 can be conveyor belts or feeding rollers, etc., and this embodiment does not limit this.

[0085] Optionally, in order to improve the transfer efficiency between the first tray and the second tray, multiple transfer mechanisms 7 can be provided, and a lifting mechanism 10 is provided at each position of the first feeding device 2 corresponding to each transfer mechanism 7, and a lifting mechanism 10 is also provided at each position of the second feeding device 5 corresponding to each transfer mechanism 7. The lifting mechanism 10 can jack up one of the first trays (or second trays) so that the corresponding transfer mechanism 7 can transfer the workpieces, and the other first trays (or second trays) can pass under the lifting mechanism 10 and be jacked up by the next lifting mechanism 10.

[0086] Furthermore, it is also common to provide a lifting mechanism 10 on the feeding device, and the specific structure of the lifting mechanism 10 is not the focus of this embodiment. Therefore, this embodiment does not elaborate on it.

[0087] See Figure 2 and Figure 3 In this embodiment, the transfer mechanism 7 includes a suction head module 701, a first linear drive mechanism 702, and a second linear drive mechanism 703.

[0088] The first linear drive mechanism 702 drives the suction head module 701 to move up and down; the second linear drive mechanism 703 drives the first linear drive mechanism 702 to reciprocate horizontally between the first feeding device 2 and the second feeding device 5.

[0089] The suction head module 701 includes a transfer motor 7011, a horizontal rotating shaft 7012, a plurality of cam members 7013, a plurality of sliding suction heads 7014, and a plurality of elastic members. The horizontal rotating shaft 7012 is drivingly connected to the transfer motor 7011 by means of belt pulley transmission. Each of the cam members 7013 is sleeved on the horizontal rotating shaft 7012 and rotates with the horizontal rotating shaft 7012; a slidable sliding suction head 7014 is provided below each of the cam members 7013. Each of the sliding suction heads 7014 is correspondingly connected to an elastic member, and the elastic member is used to drive the sliding suction head 7014 to slide upward.

[0090] Optionally, a rolling bearing 7015 is provided at a position corresponding to the cam member 7013 at the top of the sliding suction head 7014, thereby reducing the resistance between the cam member 7013 and the sliding suction head 7014 and improving the smoothness of the operation of the suction head module 701. The elastic member can be a compression spring or a tension spring, etc.

[0091] In this embodiment, the convex portions of the cam members 7013 are staggered.

[0092] It should be noted that in this embodiment, the distance between two adjacent workpieces in the first tray is small. Limited by the manufacturing process, the distance between two adjacent sliding suction heads 7014 on the suction head module 701 is large. Therefore, when multiple sliding suction heads 7014 slide down to pick up parts at the same time, not every sliding suction head 7014 can suck up a workpiece. For this reason, a cam structure is specifically adopted in this embodiment to solve the problem of the mismatch between the distances of two adjacent workpieces and two adjacent sliding suction heads 7014.

[0093] Specifically, the above step S20 can be refined as:

[0094] S201: The second linear driving mechanism 703 drives the suction head module 701 to move above the first tray, and the first sliding suction head 7014 is located directly above the first workpiece. The first linear driving mechanism 702 drives the suction head module 701 to move downward to approach the first tray;

[0095] S202: The transfer motor 7011 is started to drive the horizontal rotating shaft 7012 to rotate. The horizontal rotating shaft 7012 drives all the cam members 7013 to rotate. Since the convex portions of the cam members 7013 are staggered, when the first cam member 7013 rotates to the convex portion abutting against the first sliding suction head 7014, the convex portions of the other cam members 7013 have not yet contacted the corresponding sliding suction heads 7014;

[0096] Specifically, when the first cam member 7013 rotates to the convex portion to abut against the first sliding suction head 7014, as the first cam member 7013 continues to rotate, the first sliding suction head 7014 will slide downward, thereby sucking the first workpiece located directly below the first sliding suction head 7014;

[0097] The first cam member 7013 continues to rotate, and the convex portion of the first cam member 7013 rotates away from the first sliding suction head 7014, and the first sliding suction head 7014 slides upward under the action of the first elastic member;

[0098] S203: The second linear drive mechanism 703 drives the suction head module 701 to move horizontally a certain distance so that the second sliding suction head 7014 is located directly above the second workpiece;

[0099] The transfer motor 7011 is started to drive the horizontal rotating shaft 7012 to rotate, and the horizontal rotating shaft 7012 drives all the cam members 7013 to rotate. When the second cam member 7013 rotates to the convex portion to abut against the second sliding suction head 7014, the second sliding suction head 7014 will slide downward, thereby sucking the second workpiece located directly below the second sliding suction head 7014;

[0100] The second cam member 7013 continues to rotate, and the convex portion of the second cam member 7013 rotates away from the second sliding suction head 7014, and the second sliding suction head 7014 slides upward under the action of the second elastic member;

[0101] By repeatedly executing S203, the picking operations of all other sliding suction heads 7014 can be sequentially performed.

[0102] See Figure 4 and Figure 5 In this embodiment, the flipping mechanism 9 includes two oppositely arranged clamping assemblies 901, an installation box 902, a third linear drive mechanism 903 for driving the installation box 902 to move up and down, and a fourth linear drive mechanism 904 for driving the third linear drive mechanism 903 to reciprocate horizontally between the first feeding device 2 and the second feeding device 5.

[0103] Among them, the clamping assembly 901 includes a mounting plate 9011 whose upper part extends into the installation box 902 and a clamping plate 9012 rotatably connected to the lower part of the mounting plate 9011.

[0104] The installation box 902 is provided with a flipping motor 905 and a long rotating shaft 906. Specifically, the middle part of the long rotating shaft 906 is drivingly connected to the flipping motor 905 through a first belt 907, and the end part is drivingly connected to the clamping plate 9012 through a second belt 908. When the flipping motor 905 is started, the two clamping plates 9012 can rotate synchronously around the same horizontal axis, thereby realizing the up-and-down flipping of the transfer tray and the second tray.

[0105] The installation box 902 is provided with a clamping motor 909, a lead screw 910 and a third belt 911. The clamping motor 909 is used to drive the two mounting plates 9011 to approach or move away from each other. Specifically, one end of the lead screw 910 is connected to the driving end of the flipping motor 905, and the other end is threadedly connected to one of the mounting plates 9011. The mounting plate 9011 threadedly connected to the lead screw 910 is connected to the lower half circle of the third belt 911, and the other mounting plate 9011 is connected to the upper half circle of the third belt 911. Therefore, when the clamping motor 909 rotates forward, the lead screw 910 rotates forward, thereby driving the mounting plate 9011 connected to the lead screw 910 to move in the direction close to the clamping motor 909. The mounting plate 9011 connected to the lead screw 910 will drive the third belt 911 to rotate clockwise, thereby driving the other mounting plate 9011 to also move in the direction close to the clamping motor 909, so as to realize the clamping operation. Similarly, by rotating the clamping motor 909 in the reverse direction, the two mounting plates 9011 can be moved away from each other, thereby releasing the second tray and the transfer tray.

[0106] In this embodiment, two jacks are provided on each side surface of the second tray and the transfer tray, and two groups of pointed top plug posts 9013 are provided on the clamping plate 9012. Each group of pointed top plug posts 9013 has two, and the two groups of pointed top plug posts 9013 are arranged up and down.

[0107] Specifically, the above step S60 can be refined as follows:

[0108] S601: The clamping motor 909 drives the two clamping plates 9012 to approach each other until the transfer tray and the second tray are clamped; at this time, the group of pointed top plug posts 9013 with a higher position on the clamping plate 9012 is inserted into the jack on the side surface of the transfer tray, and the group of pointed top plug posts 9013 with a lower position is inserted into the jack on the side surface of the second tray;

[0109] S602: The third linear driving mechanism 903 drives the clamping assembly 901 to rise a little to leave a flipping space;

[0110] S603: The flipping motor 905 starts, causing the second tray and the transfer tray to flip up and down. At this time, the workpieces in the second tray will fall into the transfer tray and be in a face-up state. The original second tray is replaced by the new transfer tray, and the original transfer tray is replaced by the new fully loaded second tray.

[0111] The above step S70 can be refined as follows:

[0112] S701: The third linear drive mechanism 903 drives the clamping assembly 901 to move downward until the second tray and the transfer tray are placed on the lifting mechanism 10.

[0113] S702: The clamping motor 909 drives the two clamping plates 9012 to move away from each other, releasing the second tray and the transfer tray.

[0114] S703: The third linear drive mechanism 903 drives the clamping assembly 901 to move upward by a distance equal to the thickness of the second tray. At this time, the higher pointed top post 9013 on the clamping plate 9012 protrudes above the transfer tray, and the lower pointed top post 9013 on the clamping plate 9012 is aligned with the jack on the side of the transfer tray.

[0115] S704: The clamping motor 909 drives the two clamping plates 9012 to move closer to each other, and the lower pointed top post 9013 is inserted into the jack on the side of the transfer tray, thereby realizing clamping only the transfer tray without clamping the second tray.

[0116] S705: The third linear drive mechanism 903 drives the clamping assembly 901 to move upward, lifting the transfer tray, and the lifting mechanism 10 returns the second tray to the second feeding device 5.

[0117] It should be noted that each of the linear drive mechanisms described in this embodiment is a telescopic cylinder, a rodless cylinder, or a motor screw 910 sliding assembly, etc., and the present invention does not limit this.

[0118] The flipping feeding device provided by the present invention tears the workpiece from the first tray and places it face-down into the second tray through the transfer mechanism, and then uses the flipping mechanism to flip the workpiece up and down, thereby realizing the mechanized flipping operation of the workpiece and greatly improving the production efficiency.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
