DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] The core of the utility model is to provide a vacuum suction device which can solve the problem of strong air permeability on the surface of the carton. The negative pressure of the suction device assembly can be adjusted according to the situation of the product being adsorbed, so as to ensure a reliable adsorption effect for products with different air permeability.

[0034] The vacuum suction device provided by the utility model can solve the problem of strong air permeability on the surface of the carton, including an air compressor 1, a vacuum suction device component 5 and a control element, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 .

[0035] The vacuum suction device 5 includes a suction device assembly 51 and a negative pressure value monitoring element 52. The suction device assembly 51 can be in a common form, including a suction cup, a spring, a joint and other components, and is used to achieve the suction of the product to be sucked. The negative pressure value monitoring element 52 is used to detect the negative pressure value generated when the suction device assembly 51 sucks the product to be sucked.

[0036] The product to be adsorbed here is a carton, but it can also be a box such as a mesh box or a shell or other objects to be adsorbed, and different products have different air permeabilities.

[0037] The air inlet of the vacuum generator 55 is connected to the air compressor 1, and the vacuum port of the vacuum generator 55 is connected to the gripper assembly 51. The compressed air of the air compressor 1 generates negative pressure through the vacuum generator 55 and is provided to the gripper assembly 51, so that the gripper assembly 51 generates negative pressure to adsorb the product to be adsorbed;

[0038] After the product is reliably adsorbed, the vacuum suction device as a whole can realize the transfer of the product by connecting with the end of the robot. When the product is transferred into place, the air intake of the air inlet of the vacuum generator 55 is cut off or the vacuum generator 55 is stopped. The vacuum generator 55 no longer generates negative pressure, and the operation requirement of putting the product down can be realized.

[0039] The detection element (not shown in the figure) is used to detect the position information of the product to be adsorbed and return the product position information to the control element (not shown in the figure) through the signal connection with the control element (not shown in the figure). The control element determines whether the product is adsorbed based on the position information. If the vacuum generator 55 has started working, but the product position is still the initial position point, it means that the product is not adsorbed; if the product position has moved from the initial position point to the next position point (such as movement in the height direction), it means that the product is adsorbed.

[0040] Optionally, the detection element can be arranged on the shelf where the products are stacked, or on the opposite side of the shelf, as long as the movement of the products can be detected without interfering with the overall gripper.

[0041] Optionally, the detection element may be a sensor or an infrared detection device, which can detect the movement of the product to provide feedback on whether it is adsorbed.

[0042] The negative pressure value monitoring element 52 is connected to the control element signal, and is used to detect the negative pressure value generated by the suction assembly 51 when sucking the product. When the value fed back to the control element by the negative pressure value monitoring element 52 is 0, the negative pressure needs to be increased to suck the product, specifically, the control element controls the adjustment element to increase the negative pressure generated by the suction assembly 51 until the product is sucked up.

[0043] If the pressure value fed back to the control element by the negative pressure monitoring element 52 is the preset negative pressure value, the product is determined to be adsorbed through the position information fed back by the detection element. At this time, the product is a product that meets the requirements under the preset negative pressure value, such as a standardized product, and the adjustment element does not need to operate. If the position information fed back by the detection element determines that the product is not adsorbed under the preset negative pressure value, the product is a product with strong air permeability, and the control element needs to be used to control the operation of the adjustment element to increase the negative pressure of the suction assembly 51 to ensure that products with strong air permeability can be reliably adsorbed.

[0044] It should be noted here that the preset negative pressure value in the above process is the value originally stored in the control element, which is the preset negative pressure value corresponding to the adsorption of products that meet the requirements, such as standardized products (i.e., there are no air permeability problems, depression problems, etc., and cartons with standardized size and shape).

[0045] Next, taking the adjustment element as a component inside the air compressor 1 as an example, the adjustment element is set in the air compressor 1 and can adjust the power of the air compressor 1. The setting of the adjustment element can make the air compressor 1 have multiple power modes, such as high power mode, energy saving mode (normal operation mode), etc. By adjusting the power of the air compressor 1, the amount of compressed air entering through the air inlet of the vacuum generator 55 is adjusted to change the negative pressure generated by the vacuum generator 55, and further change the negative pressure generated by the vacuum gripper component 5.

[0046] If the value generated by the negative pressure value monitoring element 52 is 0, the control element controls the adjustment element to increase the negative pressure of the suction assembly 51 until the product is adsorbed; if the value generated by the negative pressure value monitoring element 52 is a preset negative pressure value (or within a certain range of the preset negative pressure value), the product is adsorbed, indicating that the product does not have an air permeability problem at this time and is a standardized product. At this time, the air compressor 1 can operate in the normal operation mode to ensure reliable adsorption of standardized products; if the value generated by the negative pressure value monitoring element 52 is a preset negative pressure value, the product is not adsorbed, indicating that the product is a product with strong air permeability at this time, and the air compressor 1 needs to turn on the high power mode. Specifically, the control element needs to control the adjustment element to increase the output power of the air compressor 1, so that the vacuum generator 55 generates a larger negative pressure, until the control element determines that the product is adsorbed based on the feedback information of the detection element, so as to ensure the reliable adsorption of the suction assembly 51 on the product with strong air permeability. The same batch or the same product as the product with strong air permeability can be adsorbed according to the negative pressure value of the negative pressure value monitoring element 52 at this time.

[0047] For products with good sealing properties (poor air permeability, standardized products), air compressor 1 can operate in normal operation mode. For products with strong air permeability, air compressor 1 can start high-power mode to perform targeted adsorption operations on different permeable products. There is no need for air compressor 1 to run at high power for a long time, thus reducing energy consumption.

[0048] Optionally, a numerical value may be displayed on the negative pressure value monitoring element 52, or a display panel may be provided on the control element, so that the user can conveniently and quickly obtain the negative pressure value of the suction device assembly 51 when sucking the product to be sucked.

[0049] Optionally, an alarm element connected to the control element signal can also be set. If the value fed back to the control element by the negative pressure value monitoring element 52 exceeds or approaches the maximum negative pressure value that can be output by the vacuum port of the vacuum generator 55, the control element controls the alarm element to alarm to avoid damage to components.

[0050] Optionally, a pressure regulating valve may be provided on the connecting pipeline between the air inlet of the vacuum generator 55 and the air compressor 1. The pressure regulating valve is connected to the control element signal. The pressure regulating valve is controlled by the control element to change the cross-sectional area of ​​the air flow through the connecting pipeline, thereby adjusting the air pressure reaching the vacuum generator 55 to adjust the adsorption force of the suction assembly 51.

[0051] Optionally, a valve may be provided at the air inlet of the vacuum generator 55 , and the valve is connected to a control element signal. The control element controls the valve opening to adjust the vacuum degree at the outlet of the vacuum generator 55 , thereby adjusting the adsorption force of the suction device assembly 51 .

[0052] The above can solve the problem of vacuum suction cups with strong air permeability on the surface of cartons. The vacuum suction cup component 5 includes a suction cup assembly 51 and a negative pressure value monitoring element 52. The suction cup assembly 51 is used to adsorb the product to be adsorbed, and the negative pressure value monitoring element 52 is used to detect the value generated when the suction cup assembly adsorbs the product to be adsorbed; the air inlet of the vacuum generator 55 is connected to the air compressor 1, and the vacuum port of the vacuum generator 55 is connected to the suction cup assembly 51. The compressed air of the air compressor 1 generates negative pressure through the vacuum generator 55 and is provided to the suction cup assembly 51, so that the suction cup assembly 51 generates negative pressure to adsorb the product to be adsorbed; the detection element is used to detect the position information of the product to be adsorbed and feed it back to the control element. The control element can determine whether the product is adsorbed based on the position information of the product to be adsorbed. The regulating element is connected to the control element signal to adjust the negative pressure generated by the suction assembly; when the pressure value fed back to the control element by the negative pressure detection element 52 is 0, the control element needs to control the regulating element to operate to increase the negative pressure generated by the suction assembly 51 to absorb the product; when the pressure value fed back to the control element by the negative pressure monitoring element 52 is a preset negative pressure value, if the control element determines that the product is not absorbed based on the position information of the detection element, the product at this time is a product with strong air permeability, and the control element controls the regulating element to operate to increase the negative pressure of the suction assembly 51 to ensure reliable absorption of products with strong air permeability; if the product has been absorbed under the preset negative pressure value, the product is a standardized product at this time, and the regulating element does not need to operate. The above-mentioned vacuum suction device can adjust the negative pressure of the suction assembly according to the absorption of the product to ensure reliable absorption of products with different air permeability.

[0053] On the basis of the above embodiment, a gas temporary storage component 3 is provided between the air compressor 1 and the vacuum suction device component 5, the inlet end of the gas temporary storage component 3 is connected to the air compressor 1 through the first pipeline 2, and the outlet end of the gas temporary storage component 3 is connected to the air inlet of the vacuum generator 55 through the second pipeline 4.

[0054] Please refer to Figure 1 , Figure 2 , Figure 3A gas temporary storage part 3 is provided between the air compressor 1 and the vacuum suction device part 5. The gas temporary storage part 3 can be in a can shape, a cylinder shape or other structural forms without limitation.

[0055] The inlet end of the gas temporary storage part 3 is connected to the air compressor 1 through the first pipeline 2, and the outlet end of the gas temporary storage part 3 is connected to the air inlet of the vacuum generator 55 through the second pipeline 4, so that the compressed air generates negative pressure through the vacuum generator 55, so that the suction assembly 51 generates negative pressure and adsorbs the product to be adsorbed. The compressed gas of the air compressor 1 can be temporarily stored in the gas temporary storage part 3, providing a transition space for the compressed gas. When the gas in the gas temporary storage part 3 can meet the use of the suction assembly 51 of the vacuum suction component 5, the air compressor 1 can be turned off to minimize the energy consumption of the equipment and achieve the effect of energy saving and emission reduction.

[0056] It should be noted that the gas temporary storage unit 3 itself has good sealing properties, and the gas will not leak or be mixed with impurities when not in operation, thereby ensuring reliable and safe gas transportation.

[0057] On the basis of any of the above embodiments, the first pipeline 2 and the second pipeline 4 are provided with switch valves, and the switch valves are connected to the control element signals.

[0058] Please refer to Figure 1 , Figure 2 There is no restriction on the specific shapes and numbers of the first pipeline 2 and the second pipeline 4, so long as they can meet the gas transportation requirements.

[0059] Both the first pipeline 2 and the second pipeline 4 are provided with switch valves, which can control the on / off of gas delivery to the suction device assembly 51 according to demand. The switch valves can be opened and closed manually, and can also be automatically started and stopped by a control element.

[0060] Take the example of closing or opening the switch valves on the first pipeline 2 and the second pipeline 4 by the control element; the control element controls the switch valve on the first pipeline 2 to open, so that the compressed gas in the air compressor 1 enters the gas temporary storage part 3. When the value displayed by the pressure gauge on the gas temporary storage part 3 reaches the upper limit value (the gas in the gas temporary storage part 3 is full), the control element controls the switch valve on the first pipeline 2 to close and controls the switch valve on the second pipeline 4 to open, so that the compressed air generates negative pressure through the vacuum generator 55 and is provided to the suction device assembly 51 to adsorb the product. operation; when the value displayed by the pressure gauge on the gas temporary storage part 3 reaches the lower limit (the amount of gas in the gas temporary storage part 3 is low), the control element controls the switch valve on the second pipeline 4 to open so as to deliver the compressed gas of the air compressor 1 to the gas temporary storage part 3, until the value displayed by the pressure gauge reaches the upper limit, the switch valve on the first pipeline 2 is controlled to be closed, and the switch valve on the second pipeline 4 is controlled to be opened, so as to perform the adsorption operation again; in addition, when the vacuum suction device component 5 is not operating, the control element controls the switch valves on the first pipeline 2 and the second pipeline 4 to be in a normally closed state.

[0061] Preferably, the switch valves provided in the first pipeline 2 and the second pipeline 4 are preferably solenoid valves.

[0062] Optionally, the opening of the switch valve on the second pipeline 4 can also be adjusted to adjust the cross-sectional area of ​​the airflow on the pipeline, thereby adjusting the air pressure reaching the vacuum generator 55 to adjust the adsorption force of the suction assembly 51.

[0063] Based on any of the above embodiments, the vacuum suction device component 5 includes a suction cup mounting member 53, a vacuum generator 55 is provided on the upper portion of the suction cup mounting member 53, a suction device assembly 51 corresponding to the vacuum generator 55 is provided on the lower portion of the suction cup mounting member 53, and a negative pressure value monitoring element 52 is provided on the side of the suction cup mounting member 53.

[0064] Please refer to Figure 1 , Figure 3 , Figure 4 The suction cup mounting member 53 is a two-layer structure and the two layers are connected by a connecting plate. Figure 3 As shown, the two connecting plates correspond to the left and right sides of the two-layer structure respectively, and the connection between the two-layer structure is achieved through the two connecting plates.

[0065] The upper structure of the two-layer structure is used to install the vacuum generator 55, the lower structure is used to install the suction assembly 51 corresponding to the vacuum generator 55, and the space between the upper structure and the lower structure is used to provide installation space for the connecting pipelines between the vacuum generator 55 and the suction assembly 51.
