Description

Technical Field

[0001] This utility model relates to the field of product manufacturing and testing equipment technology, and in particular to a stacked feeding device and a feeding machine. Background Technology

[0002] In the field of modern intelligent manufacturing, especially in high-speed automated production lines for precision electronic component packaging and new energy battery module production, the rapid and precise stacking and loading of multi-layer trays has become a core factor affecting overall production efficiency. Existing loading devices generally suffer from the following technical problems:

[0003] (1) Poor compatibility of multi-specification trays: Existing equipment usually adopts a fixed limiting structure, which is difficult to adapt to the continuous production needs of trays of different sizes. Frequent tooling changes result in production line downtime accounting for as high as 15%-20%, which seriously affects production efficiency.

[0004] (2) Lack of dynamic adjustment capability: During continuous production, it is impossible to compensate for the displacement of the material tray caused by transportation vibration in real time, resulting in a stacking misalignment rate of up to 8%-12%, which seriously restricts the yield rate of high-speed production lines. Utility Model Content

[0005] The purpose of this utility model is to provide a stackable feeding device and a feeding machine to alleviate the above-mentioned technical problems existing in the prior art.

[0006] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0061] Example 1

[0062] This embodiment provides a stacking feeding device, referring to... Figures 1 to 10 The stacking feeding device includes a base plate 100 and a feeding mechanism 200 mounted on the base plate 100. The base plate 100 is defined to have a front-back direction and a left-right direction, with its front-back direction as the Y-axis, its left-right direction as the X-axis, and its up-down direction as the Z-axis.

[0063] The feeding mechanism 200 of the stacked feeding device includes an adjustment mechanism and a tray lifting mechanism 2.

[0064] Its adjustment mechanism 1 includes a left limiting rod seat 11, a right limiting rod seat 12, and an X-direction displacement drive assembly 13. Multiple upwardly extending limiting rods are fixedly connected to the left limiting rod seat 11 and the right limiting rod seat 12 respectively. One of the left limiting rod seat 11 and the right limiting rod seat 12 is fixed to the base plate 100, and the other is connected to the X-direction displacement drive assembly 13. The X-direction displacement drive assembly 13 is installed on the base plate 100 and can drive the one of the left limiting rod seat 11 and the right limiting rod seat 12 that is not fixed to the base plate 100 to move along the X direction, so as to neatly arrange the stacked trays between the limiting rods of the left limiting rod seat 11 and the right limiting rod seat 12.

[0065] Its material tray lifting mechanism 2 includes a Z-direction displacement drive assembly 21 and a support plate 22. The Z-direction displacement drive assembly 21 is installed on the base plate 100, and the support plate 22 is connected to the top of the Z-direction displacement drive assembly 21 and is located between the left limit rod seat 11 and the right limit rod seat 12 for lifting the stacked material trays.

[0066] In use, the trays are stacked between the left limiting rod seat 11 and the right limiting rod seat 12 (above the pallet 22). The trays are limited in the front and back directions by means of the inner side wall of the equipment or other positioning structures inside the equipment. The X-axis displacement drive assembly 13 is activated to arrange the stacked trays neatly between the limiting rods of the left limiting rod seat 11 and the right limiting rod seat 12. Then the Z-axis displacement drive assembly 21 is activated, and the pallet 22 lifts the trays upward to send the trays to the upper position to pick up the materials layer by layer, and transfer the trays of products that have been removed layer by layer to the designated empty tray placement position.

[0067] The stacking feeding device provided in this embodiment adopts a left-right symmetrical limit rod design and is equipped with an X-direction displacement drive component 13. It can support the adaptive adjustment of the X-direction dimension of various specifications of trays after stacking. The adjustment time is short, which greatly improves the work efficiency compared with the traditional tooling replacement method. It can also maintain the limit function of stacking trays after adjustment, ensuring that the trays are not misaligned during production, thereby improving work efficiency and yield.

[0068] In detail: In an optional embodiment of this example, the X-direction displacement drive assembly 13 includes a motor 131, a transmission belt 132, a first pulley 133, a second pulley 134, and an X-direction guide rail 135. The X-direction guide rail 135 and the motor 131 are both fixed to the base plate 100. The first pulley 133 and the second pulley 134 are rotatably mounted on the base plate 100 and located at both ends of the X-direction guide rail 135. The transmission belt 132 surrounds and is drively connected to the first pulley 133 and the second pulley 134. One of the left limiting rod seat 11 and the right limiting rod seat 12 is fixedly connected to the transmission belt 132. The first pulley 133 is connected to the output shaft of the motor 131. The motor 131 can drive the first pulley 133 to rotate, causing the transmission belt 132 and the second pulley 134 to rotate, thereby moving the other of the left limiting rod seat 11 and the right limiting rod seat 12 along the X-direction guide rail 135.

[0069] In an optional embodiment of this example, multiple limiting rods of the left limiting rod seat 11 are arranged to form a U-shape with the opening facing the right, and multiple limiting rods of the right limiting rod seat 12 are arranged to form a U-shape with the opening facing the left. This allows the limiting rods on the limiting rod seat to limit the corner area of ​​the material tray. In addition to achieving the function of limiting in the X direction, it can also limit the front and rear sides of the corner area of ​​the material tray, further adjusting the material tray and improving the adjustment accuracy.

[0070] In an optional embodiment of this example, the Z-axis displacement drive component 21 is mounted on the lower surface of the base plate 100 and extends upward through the base plate 100 to ensure that there is a large material tray bearing space above the base plate 100 as much as possible.

[0071] In an optional embodiment of this example, the feeding mechanism 200 further includes a rear positioning plate mechanism 3, used to position the rear side of the stacked trays, thereby ensuring that the stacked trays have high Y-axis alignment accuracy. The rear positioning plate mechanism 3 includes a rear limiting rod 31, a second Z-axis displacement drive component 32, and a Y-axis displacement drive component 33. Specifically: the Y-axis displacement drive component 33 is mounted on the base plate 100; the second Z-axis displacement drive component 32 is mounted on the Y-axis displacement drive component 33; and the rear limiting rod 31 extends along the Z-axis and is connected to the second Z-axis displacement drive component 32. The Y-axis displacement drive component 33 is used to drive the Z-axis displacement drive component and the rear limiting rod 31 to move along the Y-axis, and the second Z-axis displacement drive component 32 drives the rear limiting rod 31 to rise and fall. The Y-axis alignment function is achieved by adjusting the rear limiting rod 31 through the Y-axis displacement drive component 33 and the Z-axis displacement drive component to align the rear side of the tray.

[0072] To further enhance driving stability, the rear positioning plate mechanism 3 may optionally include a mounting base 34, a Y-axis guide rail 35, and a slider 36 mounted on the Y-axis guide rail 35. The mounting base 34 is fixed to the slider 36, the Z-axis displacement drive assembly 32 is mounted on the mounting base 34, and the rear limiting rod 31 is slidably mounted on the mounting base 34.

[0073] In an optional embodiment of this example, the feeding mechanism 200 of the stacked feeding device includes two sets installed along the X direction on the base plate 100; and the stacked feeding device also includes a top frame 300 and a tray transfer mechanism 400. The top frame 300 is fixedly connected to the top of the base plate 100 by multiple columns, and the tray transfer mechanism 400 is installed on the top frame 300 to transfer the tray between the left limit rod seat 11 and the right limit rod seat 12 of one feeding mechanism 200 to the left limit rod seat 11 and the right limit rod seat 12 of another feeding mechanism 200, thereby realizing the rapid transfer of the tray after the product is taken out. That is, the space between the left limit rod seat 11 and the right limit rod seat 12 of one feeding mechanism 200 is used as the feeding space for the tray containing the product, and the space between the left limit rod seat 11 and the right limit rod seat 12 of the other feeding mechanism 200 is used as the placement space for the empty tray after the product is taken out, thereby further improving production efficiency.

[0074] Optionally, the aforementioned tray transfer mechanism 400 includes an X-direction displacement drive assembly 4, a top frame slide rail 5, a top fixing plate 6, a middle mounting plate 7, a lifting assembly 8, and a material handling structure 9. The top frame slide rail 5 extends along the X-direction and is fixed to the top frame 300; the top fixing plate 6 is fixed to the X-direction displacement drive assembly 4 and slidably mounted on the top frame slide rail 5; the X-direction displacement drive assembly 4 is mounted on the top frame 300 and is used to drive the top fixing plate 6 to slide along the top frame slide rail 5. The middle mounting plate 7 is mounted below the top fixing plate 6 via the lifting assembly 8. The material handling structure 9 is located on the middle mounting plate 7 and is used to transfer the material tray. During transfer, the lifting assembly 8 drives the middle mounting plate 7 to descend so that the material handling structure 9 contacts the material tray, lifts it to transfer the material tray, and then lowers it again to release the material tray, thus realizing the tray transfer action.

[0075] The material handling structure 9 can be configured to either use a suction nozzle to pick up the material tray or a mechanical claw structure to grip the material tray. When a mechanical claw structure is selected, for ease of manufacturing, the material handling structure 9 can optionally include an X-direction left telescopic drive assembly 91, a left-side gripper plate 92, an X-direction right telescopic drive assembly 93, and a right-side gripper plate 94. The X-direction left telescopic drive assembly 91 and the X-direction right telescopic drive assembly 93 are symmetrically installed on both sides of the central mounting plate 7. The left-side gripper plate 92 is fixed to the X-direction left telescopic drive assembly 91, and its lower end is located in the middle. The mounting plate 7 is below and bent to the right; the right claw plate 94 is fixed to the X-direction right telescopic drive assembly 93, and its lower end is located below the middle mounting plate 7 and bent to the left. The X-direction left telescopic drive assembly 91 and the X-direction right telescopic drive assembly 93 retract synchronously to close the left claw plate 92 and the right claw plate 94 to grab the material tray. The X-direction left telescopic drive assembly 91 and the X-direction right telescopic drive assembly 93 extend synchronously to open the left claw plate 92 and the right claw plate 94 to release the material tray, thereby realizing the tray transfer action.

[0076] Specifically, in this embodiment, the X-direction displacement drive component 13, X-direction displacement drive component 2 4, Y-direction displacement drive component 33, Z-direction displacement drive component 1 21, Z-direction displacement drive component 2 32, X-direction left telescopic drive component 91, and X-direction right telescopic drive component 93 can be selected, but are not limited to, combinations of motor and telescopic rod, combinations of motor and ball screw, various forms of electric slides, electric push rods, combinations of motor and transmission wheel sets and transmission belts (or chains), or combinations of cylinder and telescopic rod, hydraulic cylinder and telescopic rod, electric cylinder and telescopic rod, etc., any structure that can realize displacement drive.
