Description

Technical Field

[0001] The utility model relates to the field of automated production equipment, in particular to a tray stacking mechanism. Background Art

[0002] Current industrial automation production is gradually moving toward modularization, high speed, and compatibility with multiple specifications. Material trays are widely used in the automated production of electronic products, particularly in automated production lines for small-scale mass-produced industrial products such as mobile phones, batteries, and glass. Material trays are typically injection-molded from rigid plastic and feature several grooves to hold the electronic components, allowing them to circulate on automated production lines. Since it's difficult to ensure perfect timing consistency between workstations as the material trays circulate on the production line, and the flow of material trays on the production line isn't linear and uniform, a material tray access mechanism is required to coordinate operations at different workstations. In existing technology, material trays are typically retrieved and placed by installing a robotic arm. However, installing a robotic arm is costly, requires a large installation space, and requires complex programming, making operation difficult. This makes it difficult to use in narrow spaces and compactly arranged equipment, making it unsuitable for robotic installation. Manual operation is slow and inefficient. Utility Model Content

The directional terms used are for better and clearer explanation and understanding of the present invention, rather than indicating or implying the orientation that the present invention must have, and therefore cannot be understood as a limitation on the present invention.

[0020] The present utility model is implemented as follows Figures 1 to 3As shown in, a material tray stacking mechanism includes a material bin 1 for storing material trays 6, and the material bin 1 includes four support columns 12 in an L-shaped structure located at the four vertices of a rectangle, and the two ends of the L-shaped structure of each support column 12 correspond to the two support columns 12 adjacent to it, that is, the four support columns 12 enclose a rectangular space, and the bending vertex of the L-shaped structure of each support column 12 faces the outside of the space. The L-shaped structure of the support column 12 can well position the material tray 6 in the material bin 1, and a feeding port 10 is provided at the bottom of the material bin 1, which means that the material of the material bin 1 is fed from the bottom of the material bin 1. At this time, the four support columns 12 of the material bin 1 can be erected above the production line, and a material feeding port 10 is provided directly below the feeding port 10. There is a jacking mechanism 2 at a certain distance, and the jacking mechanism 2 is set on the production line. The distance between the jacking mechanism 2 and the silo 1 makes it convenient for the material tray 6 to be transported from the production line to the jacking mechanism 1. The material tray 6 is lifted by the jacking mechanism 2 and passed through the feed port 10 to be transported to the silo 1 for storage. At the same time, a sensor 5 for sensing the material tray 6 is set on the upper part of the silo 1. The sensor 5 uses a photoelectric sensor. The sensor 5 is set at a certain height above the silo 1. When the sensor 5 senses the material tray 6 at this height, it means that the silo 1 is full of material trays 6; the edges of the inner wall of the silo 1 adjacent to the feed port 10 on both sides are rotatably provided with a one-way buckle that can be unidirectionally engaged with the material tray 6, that is, the one-way buckle is set on the inner wall of the silo 1 and is at the feed port When the hopper 1 is lifted up, the hopper 1 is lifted up and the hopper 1 is in a closed position, and the hopper 1 is in a closed position, and the hopper 1 is in a closed position, and the hopper 1 is in a closed position, and the hopper 1 is in a closed position, and the hopper 1 is in a closed position, and the hopper 1 is in a closed position, and the hopper 1 is in a closed position, and the hopper 1 is in a closed position, and the hopper 1 is in a closed position, and the hopper 1 is in a closed position, and the hopper 1 is in a closed position, and the hopper 1 is in a closed position, and the hopper 1 is in a closed position, and the hopper 1 is in a closed position, and the hopper 1 is in a closed position, and the hopper 1 is in a closed position, and the hopper The lifting mechanism 2 is provided with a clamping cylinder 4 at the top for pushing the one-way buckle to rotate upward and disengage from the engagement with the material tray 6. The clamping claws of the clamping claw cylinder 4 are arranged as parallel clamping claws of a square structure, which are arranged in the middle position of the top of the lifting mechanism 2.When storing the material tray 6, the clamping claw of the clamping claw cylinder 4 is in a closed state. After the material tray is transported from the production line, it is placed on the top of the clamping claw of the clamping claw cylinder 4. Then, as the lifting mechanism 2 rises, the material tray 6 drives the one-way buckle to rotate upward, thereby placing the material tray 6 into the silo 1; when taking the material tray 6, as the lifting mechanism 2 rises, the clamping claw cylinder 4 rises synchronously, and the clamping claw of the clamping claw cylinder 4 is synchronously expanded and abutted on the one-way buckle. The one-way buckle is driven to move upward, and the one-way buckle can also push and press against it. The material tray 6 on the upper part moves upward, and as the lifting mechanism 2 and the clamping cylinder 4 continue to rise, the one-way buckle disengages from the material tray 6, and the material tray 6 at the bottom is pressed against the top of the clamping claw of the clamping claw cylinder 4. Then, as the lifting mechanism 2 descends, the material tray 6 is taken out from the silo 1 as it descends. At this time, the material tray 6 on the top of the clamping claw cylinder 4 descends with the lifting mechanism 2, and the one-way buckle is reset synchronously to block the material tray 6 above it, thereby completing the removal of the material tray 6. When the silo 1 is composed of support columns 12, the two one-way clips are installed between two adjacent support columns 12 through the mounting base 31. The mounting base 31 is set at the lower ends of the two support columns 12. For example, the left mounting base 31 is set at the lower ends of the two left support columns 12, and the right mounting base 31 is set at the lower ends of the two right support columns 12. In this way, the mounting base 31 and the two corresponding support columns 12 form a U-shaped support member. Of course, the four support columns 12 constituting the silo 1 can also be configured as two U-shaped support members arranged in parallel at intervals. Then, the one-way clip is installed on the inner bottom surface of the U-shaped structure. In this case, the inner bottom surface of the U-shaped structure serves as the surface of the mounting base 31, or an additional mounting base 31 is set on the inner bottom surface of the U-shaped structure to install the one-way clip.

[0021] Further improvements, such as Figures 1 to 3As shown in the figure, the silo 1 is provided with grooves 11 on the edges of the inner wall adjacent to the feed port 10 on both opposite sides. The one-way clip is rotatably installed in the groove 11. That is to say, the grooves 11 are provided on the left and right sides, or the front and rear sides, of the inner wall of the silo 1. The one-way clip is installed in the groove 11, which facilitates the installation and rotation of the one-way clip. In this case, the groove 11 can also be provided as a groove with a through hole at the bottom of the groove. The one-way clip is a rotating block 3 that can be rotated up and down and is provided in the groove 11. The initial position of the rotating block 3 is in the horizontal position. In the horizontal position, part of the rotating block 3 protrudes outside the groove 11. In the vertical position, the rotating block 3 is flush with the inner wall of the silo 1. If the groove 11 is provided on the left and right sides of the inner wall of the silo 1, the rotation of the rotating block 3 in the groove 11 is to provide corresponding rotating holes and rotating axes between the front side wall of the groove 11 and the front end face of the rotating block 3, and between the rear side wall of the groove 11 and the rear end face of the rotating block 3. Yes, for example, the rotating holes are set on the front side wall and the rear side wall of the groove 11 and are set as through holes, the rotating shaft is set on the front end face and the rear end face of the rotating block 3, and then the rotating shaft on the rotating block 3 is installed in the corresponding rotating holes; the initial state of the rotating block 3 is in a horizontal position, and the rotating block 3 will rotate upward after being subjected to an upward force. When the rotating block 3 is rotated to a vertical position, it is flush with the inner wall of the silo 1, that is, it is hidden in the groove 11, and will not affect the entry and exit of the material tray 6 in the silo 1. When the upper force disappears, the rotating block 3 is restored to the horizontal position under the action of the torsion spring. When the rotating block 3 is subjected to the downward force, the rotating block 3 does not rotate downward, forming a unidirectional motion structure. At this time, the part of the rotating block 3 protruding from the groove 11 plays a bearing role for the material tray 6 above the rotating block 3; the groove wall at the top of the groove 11 is provided with an avoidance notch 110 for avoiding the rotating block 3, and a torsion spring (not shown in the figure) is provided between the rotating block 3 and the groove wall of the groove 11. The avoidance notch 110 is provided on the side wall above the groove 11. When the rotating block 3 rotates upward, it will not affect the upward rotation of the rotating block 3, and the rotating block 3 can be well hidden. The groove wall below the groove 11 forms a barrier to the downward rotation of the rotating block 3, so that the rotating block 3 can only rotate upward but not downward in the initial state, forming a unidirectional rotation structure; the torsion spring can be sleeved on the rotating shaft between the rotating block 3 and the groove wall of the groove 11, and then the two ends of the torsion spring are correspondingly connected to the groove wall of the rotating block 3 and the groove 11. When the silo 1 is composed of four support columns 12 and the one-way clip is installed on the mounting seat 31, the groove 11 is set on the inner wall of the mounting seat 31 facing the inside of the silo 1, and the avoidance gap 110 is located on the upper side wall of the mounting seat 31.The bottom surface of the rotating block 3 protruding from the outside of the groove 11 is provided with a first inclined surface 30 extending from the bottom to the top and away from the end surface of the groove 11. In this way, when the material tray 6 is stored, it is convenient for the material tray 6 to move upward with the lifting mechanism 2 and for the material tray 6 to push the rotating block 3 upward. At the same time, the end surface of the rotating block 3 adjacent to the bottom of the groove 11 can be set as an outward convex arc surface, and the axis direction of the arc surface is guaranteed to be the same as the axis direction of the rotating shaft. The groove 11 is provided with a second inclined surface 111 extending from the bottom to the top and to the avoidance gap 110 on the groove wall on the side of the avoidance gap 110. When the rotating block 3 is in a horizontal position, the first inclined surface 30 and the second inclined surface 111 are parallel to each other. The setting of the second inclined surface 111 prevents the side wall above the groove 11 from obstructing the rotation of the rotating block 3. The groove 11 is provided with a third inclined surface 112 extending from top to bottom on the groove wall opposite to the avoidance notch 110 , which enlarges the movable space of the rotating block 3 when rotating near one end of the groove bottom 11 .

[0022] Further improvements, such as Figure 1 and Figure 2 The two jaws of the clamping cylinder 4 are opened and closed left and right or opened and closed front and back, and the top of the clamping claw is flush with the top of the top plate 21, so that the material tray 6 can be conveniently transported while maintaining the stability of the material tray 6 on the top plate 21.

[0023] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, such modifications or improvements, without departing from the spirit of the present invention, are within the scope of protection claimed herein.
