Description

Technical Field

[0001] This utility model relates to the field of metal product handling technology, specifically to a palletizing device. Background Technology

[0002] In the process of stacking small and medium-sized water tank components for photovoltaic applications, traditional electromagnetic adsorption is often used. However, when using electromagnetic adsorption to adsorb lighter metal products for translational movement, it is easy to lift already stacked metal products, causing stacking misalignment and disordered placement of metal products. Furthermore, when using electromagnetic adsorption to adsorb lighter metal products for high-speed translational movement, the metal products may swing, which seriously affects the stacking accuracy of the metal products. Utility Model Content

[0003] In view of this, the present invention provides a palletizing device to solve the problem that when using electromagnetic adsorption to adsorb lighter metal products for translational movement, it is easy to lift the already stacked metal products, causing palletizing misalignment and disordered placement of metal products; and that when using electromagnetic adsorption to adsorb lighter metal products for high-speed translational movement, the metal products swing, which seriously affects the accuracy of palletizing and placing metal products.

[0004] This utility model provides a palletizing device, comprising:

[0005] Support structure;

[0006] A horizontal frame is disposed on the top surface of the supporting structure;

[0007] Two parallel slide rails are spaced apart and mounted on the horizontal frame;

[0008] A first rack is disposed on the horizontal frame, and the first rack is parallel to the slide rail;

[0009] The slide table is slidably connected to two slide rails;

[0010] The first power component is mounted on the slide table;

[0011] The first gear is connected to the first power component, and the first gear meshes with the first rack;

[0012] A vertical frame is mounted on the slide platform;

[0013] The second rack is arranged vertically on the vertical frame;

[0014] A carriage is provided to slide around the vertical frame.

[0015] The second power component is mounted on the carriage.

[0016] The second gear is connected to the second power component, and the second gear meshes with the second rack;

[0017] A bracket is connected to the bottom surface of the carriage;

[0018] At least one double-layer suction cup is disposed on the bottom surface of the bracket;

[0019] The palletizing device is adapted to have a first gear rotated by a first power component, thereby moving the slide table along the slide rail on a horizontal plane; and is also adapted to have a second gear rotated by a second power component, thereby moving the slide frame along a vertical frame; and is adapted to have metal products adsorbed by a double-layer suction cup. Beneficial effects: By adopting the above technical solution, the double-layer suction cup can reduce the probability of scratching the surface coating of metal products to zero when in contact with materials such as metal products, improving the quality of the metal products; at the same time, when dealing with metal products whose gripping point is not a 180° plane, the double-layer suction cup has compressibility, which can be compressed according to the different shapes of the metal products. When dealing with metal products of various shapes, it can more firmly adhere to the surface of the metal products, firmly adsorb the metal products, and ensure that the metal products will not swing significantly at the placement position, thereby improving palletizing accuracy and success rate. In addition, after the adsorption action is completed, the double-layer suction cup will not cause the metal products to become magnetic. When stacking lighter metal products, the already stacked metal products will not be lifted again due to the magnetic properties of the metal products, thus increasing the need for manual intervention and increasing costs. Even at high speeds, metal products maintain a stable posture, significantly improving the efficiency of palletizing operations. Compared to traditional electromagnetic adsorption methods, the vacuum adsorption method used in this application greatly reduces setup costs and offers greater flexibility. In terms of maintenance, the vacuum adsorption method eliminates the electromagnetic adsorption function, resulting in a lower failure rate and significantly reduced maintenance costs. The adsorption power of the double-layer suction cup is provided by compressed gas, which significantly reduces energy consumption costs compared to electrically driven electromagnetic adsorption and avoids generating new pollution sources, meeting the requirements of green development. Furthermore, by utilizing the first gear and rack, the double-layer suction cup performs precise horizontal movement; by utilizing the second gear and rack, it performs precise vertical movement, accurately picking up and placing metal products.

Beneficial effects: This application adopts the above technical solution, arranging a positive pressure vacuum generator on the support, which shortens the distance between the double-layer suction cup and the positive pressure vacuum generator, reduces the time required to create the required negative pressure environment, and improves work efficiency.

The closed-frame form of the fitting is compressible, which can prevent the low success rate of gripping due to uneven metal surfaces during rapid movements in actual use environments.

[0045] Existing palletizing devices, if employing electromagnetic adsorption structures, are complex in design, difficult to assemble, and costly. Furthermore, existing palletizing devices struggle to stably grip objects that are not on a 180° plane, limiting their usability. For these reasons, this application proposes an improved palletizing device.

[0046] like Figures 1 to 4 One specific embodiment of the palletizing device shown includes: a support structure, a horizontal frame 6, two parallel slide rails 16 spaced apart, a first rack 25, a slide table 29, a first power component 14, a first gear, a vertical frame 5, a second rack 27, a slide 30, a second power component 15, a second gear, a bracket 9, and at least one double-layer suction cup 17.

A gas source is connected to the positive pressure vacuum generator 3 via a positive pressure conduit 11 to provide a positive pressure gas source to the positive pressure vacuum generator 3; the positive pressure vacuum generator 3 is adapted to convert the positive pressure gas source into a negative pressure gas source. The negative pressure main conduit 12 is arranged along the length of the support 9 and is connected to the positive pressure vacuum generator 3. The negative pressure branch conduit 10 connects the negative pressure main conduit 12 and the double-layer suction cup 17. The pressure gauge 4 can be connected to the negative pressure gas source outlet of the positive pressure vacuum generator 3 to monitor and display the gas pressure value of the negative pressure gas source in real time. Specifically, the negative pressure branch conduit 10 is connected to the negative pressure main conduit 12 via a quick-connect tracheal tee 8; the negative pressure branch conduit 10 is connected to the double-layer suction cup 17 via a quick-connect tracheal connector 18.

[0049] like Figure 2 and Figure 3 As shown, the palletizing device described in this application further includes: a solenoid valve 28; the solenoid valve 28 is connected to the air source, and the solenoid valve 28 is adapted to control whether the air source provides positive pressure air to the outside.

[0050] Specifically, such as Figure 4 As shown, the double-layer suction cup 17 is connected to the bottom surface of the bracket 9 via a connecting structure.

[0051] like Figure 4 As shown, the connection structure includes a fitting 23 and a compressible movable tube 19. The fitting 23 is a closed frame and can be made of profile. The top surface of the fitting 23 is connected to the bottom surface of the bracket 9 by a fastener 24, which can be a screw. The lower end of the compressible movable tube 19 is connected to the top surface of the double-layer suction cup 17; the upper end of the compressible movable tube 19 is threaded to the bottom surface of the fitting 23 by a screw 20. The positive pressure vacuum generator 3, the fitting 23, and the double-layer suction cup 17 described in this application can together form a mechanical gripper.

[0052] Furthermore, such as Figure 4 As shown, a first locking nut 21 is screwed onto one end of the screw 20 that passes through the bottom surface of the fitting 23, and a second locking nut 22 is screwed onto the other end of the screw 20.

[0053] Specifically, such as Figure 1 As shown, the support structure includes a fixed base 1 and a support column 2. The support column 2 is hollow inside and is fixedly installed on the top surface of the fixed base 1. Cement is poured into the interior of the support column 2. The support column 2 is welded to the top surface of the fixed base 1.

[0054] Specifically, such as Figure 1 and Figure 3 As shown, the horizontal frame 6 is fixedly mounted on the top surface of the support structure via a fixing plate 13; specifically, screws can be used to connect the horizontal frame 6, the fixing plate 13, and the support structure. The bracket 9 is connected to the bottom surface of the slide 30 via a connecting plate 7; the connecting plate 7 can be a square plate. The vertical frame 5 is connected to the slide 29 via a fixing seat 26.

[0055] The working process of the palletizing device described in this application is briefly described as follows:

[0056] After the palletizing device is powered on, the first power component 14 starts, and the slide table 29 moves upward above the picking point according to the preset palletizing program, and stops after reaching the picking point; then the second power component 15 starts, and the slide 30 moves towards the picking point under the preset program signal. After reaching the picking point, the solenoid valve 28 is energized to provide a positive pressure air source to the positive pressure vacuum generator 3. The positive pressure vacuum generator 3 converts the positive pressure air source into a negative pressure air source. The negative pressure air source is connected to each negative pressure branch conduit 10 through the negative pressure main conduit 12 and then through the quick-connect tee 8. With the connection of the quick-connect tee 18, a negative pressure environment is formed in the inner cavity of the double-layer suction cup 17 to adsorb metal products and other adsorbents or materials. After the adsorption action is completed according to the preset palletizing program, the slide 30 moves upward to a safe position; then the slide table 29 moves above the discharge point, and the slide 30 moves downward until it reaches the preset discharge point; subsequently, the solenoid valve 28 stops supplying power, stops providing positive pressure air, and the inner cavity of the double-layer suction cup 17 returns to normal pressure, causing the adsorbed material to fall. This completes the first cycle of the palletizing device. Subsequent cycles of the same type of action are then performed according to the preset palletizing program. After the palletizing action is completed, the program automatically stops, waiting for the next cycle.
