Description

Technical Field

[0001] This utility model relates to the field of instrument box palletizing technology, and more specifically, to an automatic palletizing machine. Background Technology

[0002] Currently, after the instruments are assembled, they need to be stored in collection boxes. After the instruments are placed in the collection boxes and the collection boxes are sealed and packaged, several collection boxes are transported sequentially to the end area of ​​the conveying equipment. Then, the robotic arm at the end of the conveying equipment, in conjunction with the vacuum adsorption component, neatly stacks the instrument collection boxes onto the pallet according to the pre-set program. This can significantly reduce the labor intensity of manual stacking and has a high degree of automation.

[0003] However, current methods using robotic arms and vacuum adsorption components to adsorb instrument cases lack dust removal and static electricity elimination designs for the case surface. If the case surface has a lot of dust and large particles, it will reduce the sealing performance of the vacuum suction cup, leading to an increased leakage rate. This can easily cause the case to slip or shift during the palletizing process. Furthermore, a large amount of static electricity on the instrument case surface will also reduce the adsorption force, posing a safety hazard. Insufficient vacuum adsorption can easily cause the case to fall and damage the instrument. Therefore, these problems exist in the current automatic palletizing process for instrument cases and urgently need to be solved. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0032] like Figure 1 As shown, an automatic palletizing machine includes a conveying device 1 (specifically a belt conveyor), a robotic arm 2 located at the end of the conveying device 1, a vacuum adsorption assembly 3 connected to the robotic arm 2, and a tray 4 placed on the ground to one side of the robotic arm 2. It also includes a limiting frame 5, a dust removal chamber 6, a suction assembly 7, an anti-static component 8, a thickness detection component 9 (specifically a non-contact laser thickness sensor), a vision inspection component 10, and a controller.

[0033] The limit frame 5 is installed at the end area of ​​the conveyor 1 and is spaced apart from the belt of the conveyor 1;

[0034] The dust removal chamber 6 is mounted on the conveying equipment 1, and the dust removal chamber 6 has an inlet and an outlet on both sides (the inlet and outlet are shown in the figure but are not labeled).

[0035] The adjustable suction component 7 and the static eliminator 8 are both located inside the dust removal chamber 6, and the static eliminator 8 is connected to the suction component 7 (specifically, the static eliminator 8 is an ionizing air bar).

[0036] The thickness detection element 9 and the visual inspection element 10 are both mounted on the suction assembly 7. The thickness detection element 9 and the suction assembly 7 are electrically connected to the controller, and the visual inspection element 10 and the conveying device 1 are electrically connected to the controller.

[0037] Specific implementations of this utility model embodiment, such as Figure 1 As shown, the suction assembly 7 includes a suction hood 71, a pipe 72, a filter 73, a dust removal fan 74, and a telescopic cylinder 75.

[0038] The suction hood 71 is located inside the dust removal chamber 6, and the suction hood 71 is connected to a pipe 72 that slides with the top of the dust removal chamber 6.

[0039] The input end of filter 73 is connected to one end of pipe 72;

[0040] The dust removal fan 74 is connected to the output end of the filter 73, and both the dust removal fan 74 and the filter 73 are fixed on the pipeline 72;

[0041] The telescopic cylinders 75 are symmetrically fixed on the dust removal chamber 6 and connected to the suction hood 71;

[0042] The thickness detection component 9 and the telescopic cylinder 75 are electrically connected to the controller.

[0043] To measure the total weight of the instrument storage boxes stacked on pallet 4 in real time and reduce the risk of subsequent transportation caused by overloaded stacking, further optimizations to the above embodiment are made, such as... Figure 2 As shown, the tray 4 is placed on the weighing device 13. An electronic indicator is provided on one side of the weighing device 13. Both the electronic indicator and the weighing device 13 are electrically connected to the controller (the electronic indicator is not shown in the figure).

[0044] To prevent static electricity from being generated on the surface of the limit frame 5 and then transferred to the surface of the instrument storage box during limiting, the above embodiment is further optimized by using an anti-static hollow board 12 for the limit frame 5, and the limit frame 5 is connected to an independent grounding pile through a copper strip.

[0045] It should be noted that the conveying equipment 1, robotic arm 2, dust removal fan 74, telescopic cylinder 75, antistatic component 8, thickness detection component 9, visual inspection component 10, weighing device 13, and electronic indicator are all electrically connected to the controller, which is shown in the figure without a number.

[0046] The working process of this utility model:

[0047] First, the instrument storage boxes to be stacked are transported by the conveyor 1 (each instrument storage box weighs less than 30KG and is not numbered in the figure). Then, after the instrument storage box enters the dust removal chamber 6 from the entrance, it will pass under the thickness detection component 9 (the speed of the box passing under the laser thickness sensor should not be too fast to ensure that the laser thickness sensor has enough time to capture the change in the height of the box). At this time, the thickness detection component 9 can automatically detect the height of the instrument storage box (i.e., L1). The initial distance (L2) between the suction hood 71 and the belt of the conveyor 1 is determined (this height will not hinder the movement of the instrument storage box). Then, the controller can control the telescopic cylinder 75 to move by calculation, so that the distance between the suction hood 71 and the upper surface of the instrument storage box is kept within the value range (5-8cm) set in the controller in advance. This is to improve the effect of dust suction and removal on the surface of the instrument storage box.

[0048] When the visual inspection unit 10 detects the instrument storage box, it immediately sends a signal to the controller. The controller then stops the conveying equipment 1 and begins dust extraction. After a fixed time of extraction, the controller restarts the conveying equipment 1, and the instrument storage box continues to move. The instrument storage box then passes under the ion bar (the width of the ion bar is greater than the width of the instrument storage box). After most of the electrostatic removal process on the surface of the instrument storage box is completed, the instrument storage box can move from the outlet to the outside of the dust removal chamber 62. It should be noted that the instrument storage box must stay for more than 1 second when passing under the ion bar.

[0049] Once the instrument storage box contacts the limit frame 5, it can stop moving forward (there is no static electricity on the surface of the limit frame). Then, the controller controls the robotic arm 2 and the vacuum adsorption component 3 to operate, so that the instrument storage box can be neatly transferred and stacked on the tray 4. At this time, the dust and static electricity on the surface of the instrument storage box before vacuum adsorption are greatly reduced, which greatly reduces the probability of the instrument storage box slipping or shifting during the subsequent stacking process. The vacuum adsorption effect is firm, and the safety during the stacking process is greatly improved. By repeating the above process, the automated stacking process of the instrument storage box can be realized on the production line.

[0050] In some embodiments, such as Figure 2 As shown, the conveying equipment 1 is equipped with a positioning assembly, which includes an electric push rod 11, an anti-static hollow plate 12, and an insulating pad.

[0051] Electric push rods 11 are symmetrically arranged at the end of the conveying device 1, and the outer shell of the electric push rods 11 is grounded;

[0052] The antistatic hollow plate 12 and the electric push rod 11 are connected, and an insulating gasket is provided on the contact surface between the two (the insulating gasket is not shown in the figure).

[0053] In a further optimization of the above embodiment, the surface of the antistatic hollow board 12 is coated with a nano antistatic coating and connected to an independent grounding pile via a copper strip. In this embodiment, the positioning component can limit the position of the instrument storage box after it comes into contact with the limiting frame 5, thereby improving the accuracy of the subsequent vacuum adsorption process and reducing adsorption deviation. At the same time, during positioning, static electricity can be prevented from being conducted to the surface of the instrument storage box, resulting in a better stacking process for the instrument storage box.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
