Description

Technical Field

[0001] The utility model relates to the technical field of valve islands, and particularly relates to a base structure for a valve island supporting extended functions. Background Technique

[0002] Vacuum equipment is a device for generating, improving, and / or maintaining a vacuum, including vacuum application equipment and vacuum acquisition equipment. Vacuum generators and vacuum pumps both belong to vacuum equipment. As a means to achieve automation, vacuum equipment has been widely used in many aspects such as electronics, semiconductor component assembly, automobile assembly, automatic handling machinery, light industrial machinery, food machinery, medical machinery, printing machinery, plastic products machinery, packaging machinery, forging machinery, robots, etc.

[0003] With the development of life and the progress of technology, vacuum equipment is gradually developing towards high integration, and valve island-type vacuum equipment (such as valve island-type vacuum generators and valve island-type vacuum pumps) has emerged as the times require. Valve island-type vacuum equipment integrates the input or output of signals and the control of signals. Just like a control island, valve island-type vacuum equipment is a new generation of gas-electric integrated control components. Valve island-type vacuum equipment greatly simplifies the commissioning, performance detection, diagnosis, and maintenance of complex systems and has broad application prospects.

[0004] The bus base is one of the core components of island-type vacuum equipment. In the prior art, there are mainly two forms of bus bases. One is a bus valve unit fixedly arranged directly at the bottom of the vacuum generation unit. For example, a vacuum island disclosed in a Chinese invention patent (publication number: CN118462875A). After the valve island is assembled, each bus valve unit is connected in sequence to form the bus base. However, the defect of this structure is that since the bus valve unit is directly arranged at the bottom of the vacuum generation unit, that is, the bus valve unit and the vacuum generation unit are an integrated module. Therefore, when a certain vacuum generation unit fails and needs to be maintained or replaced, the entire valve island assembly needs to be disassembled, and the operation is cumbersome and inconvenient.

[0005] The other is to set a separate bus plate. For example, a bus valve island disclosed in a Chinese invention patent (publication number: CN113507804A) includes a bus plate. A plurality of ventilation holes are arranged on the bus plate. The solenoid valve is detachably connected to the bus plate through the ventilation holes, and the bus plate is provided with a wire groove in which a bus socket and a plurality of wiring components are installed. However, the defect of this structure is that since the number of ventilation holes on its bus plate is limited, the number of solenoid valves that can be connected is also limited, so the expansion function of the bus plate cannot be realized; and its electrical connection is achieved through wire harnesses, so there will be many lines, making the lines complex, the use cumbersome, and the maintenance inconvenient.

[0006] Therefore, it is necessary to improve the prior art. Summary of the Invention

[0007] The object of the present utility model is to provide a base structure for a valve island supporting expansion functions, which can conveniently realize the expansion function of the base, and replaces the traditional wire harness connection method with the plug-in connection method of the pin and the socket, making the electrical connection of the base more convenient.

[0012] Further, a first bolt is horizontally penetrated through the first mounting seat, the base and the second mounting seat to realize the detachable fixed connection of the first mounting seat, the base and the second mounting seat.

[0013] Further, a first air port and a second air port are arranged on the base, and a first air passage communicated with the first air port and a second air passage communicated with the second air port are arranged inside the base; when a plurality of bases are stacked, the positions of the first air passages correspond and are communicated with each other to jointly form a first confluence channel, and the positions of the second air passages correspond and are communicated with each other to jointly form a second confluence channel; the first confluence channel and the second confluence channel are arranged separately from each other.

[0014] Further, the first mounting base and / or the second mounting base are provided with a third air port and a third air passage for connecting the third air port and the first confluence passage, and the first mounting base and / or the second mounting base are further provided with a fourth air port and a fourth air passage for connecting the fourth air port and the second confluence passage.

[0015] Further, it further includes a cover plate cooperating with the base, and the lower end surface of the cover plate is provided with a first plug corresponding to and cooperating with the first air port and a second plug corresponding to and cooperating with the second air port.

[0016] Further, a first sealing ring is arranged between the first air port and the first plug, and a second sealing ring is arranged between the second air port and the second plug.

[0017] Further, a silencing device is arranged at the fourth air port.

[0018] Further, a connecting block is arranged at the fourth air port, the connecting block is provided with a fifth air port, and a fifth air passage communicating the fifth air port and the fourth air port is arranged inside the connecting block.

The expansion function of the base is realized by detachably arranging a plurality of bases between the first mounting base and the second mounting base. When it is necessary to increase the number of bases, loosen the first bolt and take it out, after adding the required number of bases, then tighten the first mounting base, the base and the second mounting base with the first bolt. At the same time, spare bases can also be configured to facilitate customers to expand external vacuum equipment. For example, in the case of needing to use N vacuum equipment, assemble N + 1 bases between the first mounting base and the second mounting base, and install a cover plate on one of the bases. When it is necessary to enable the (N + 1)-th base, just remove the cover plate and plug the vacuum equipment onto the spare base.

Any two adjacent bases are plugged and matched through the corresponding first electrical signal socket and second electrical signal socket to achieve electrical connection between the two adjacent bases. The first electrical signal socket is a first row of pins, and the second electrical signal socket is a first row of female connectors. The plugging and matching of the first row of pins and the first row of female connectors replace the traditional wire harness connection. This structural design makes the electrical connection between adjacent bases more convenient. Instead of sorting out the wire harness and then connecting it to the corresponding end, only need to insert the first row of pins into the first row of female connectors. Moreover, this structure makes the overall structure of the installed base more compact and beautiful. Brief Description of the Drawings

[0049] It should be noted that, without conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0050] Such as Figures 1 to 18As shown in the figure, a base structure for a valve island supporting extended functions includes a plurality of bases 1, which are stacked in the X-axis direction, and the plurality of bases 1 cooperate to form a confluence channel for air flow; a circuit board A11 is arranged in each base 1, and a first electrical signal socket 12, a second electrical signal socket 13 and a third electrical signal socket 14 respectively electrically connected to the circuit board A11 are arranged on the base 1. Any two adjacent bases 1 are plugged and matched through the corresponding first electrical signal socket 12 and second electrical signal socket 13 to realize the electrical connection between two adjacent bases 1; the base 1 is electrically connected to an external device through the third electrical signal socket 14. It further includes a first mounting seat 2 and a second mounting seat 3. The plurality of bases 1 are connected in series between the first mounting seat 2 and the second mounting seat 3 in the X-axis direction. A circuit board B21 is arranged in the first mounting seat 2, and a fourth electrical signal socket 22 electrically connected to the circuit board B21 is arranged on the first mounting seat 2. The fourth electrical signal socket 22 is electrically connected to the first electrical signal socket 12 of the outermost base 1. It further includes a control box 4, the control box 4 is fixedly connected to the first mounting seat 2, a circuit board C41 is arranged in the control box 4, a fifth electrical signal socket 42 electrically connected to the circuit board C41 is arranged on the control box 4, and a sixth electrical signal socket 23 electrically connected to the fifth electrical signal socket 42 is further arranged on the first mounting seat 2. A first bolt 5 is horizontally penetrated through the first mounting seat 2, the base 1 and the second mounting seat 3 to realize the detachable fixed connection of the first mounting seat 2, the base 1 and the second mounting seat 3.

[0051] Based on the above embodiments, the utility model aims to provide a base structure for a valve island supporting extended functions, including a plurality of bases 1, which are stacked along the X-axis direction, and the plurality of bases 1 cooperate to form a confluence channel for air flow; it further includes a first mounting seat 2 and a second mounting seat 3, and the plurality of bases 1 are connected in series between the first mounting seat 2 and the second mounting seat 3 along the X-axis direction; it also includes a cover plate 8 cooperating with the base 1, and a first plug 81 corresponding to and cooperating with the first air port 15 and a second plug 82 corresponding to and cooperating with the second air port 16 are arranged on the lower end surface of the cover plate 8. A first bolt 5 is horizontally penetrated through the first mounting seat 2, the second mounting seat 3 and the base 1 to realize the detachable fixed connection of the first mounting seat 2, the second mounting seat 3 and the base 1. The extended function of the base is realized by detachably arranging a plurality of bases 1 between the first mounting seat 2 and the second mounting seat 3. When it is necessary to increase the number of bases 1, loosen the first bolt 5 and take it out, add the required number of bases 1, and then tighten the first mounting seat 2, the base 1 and the second mounting seat 3 with the first bolt 5. At the same time, spare bases 1 can also be configured to facilitate customers to expand external vacuum equipment. For example, in the case of needing to use N vacuum equipment, assemble N + 1 bases 1 between the first mounting seat 2 and the second mounting seat 3, and install a cover plate 8 on one of the bases 1. When it is necessary to enable the (N + 1)-th base 1, just remove the cover plate 8 and plug the vacuum equipment onto the spare base 1. In this embodiment, the number of bases 1 that can be assembled between the first mounting seat 2 and the second mounting seat 3 is limited by the number of PIN feet of the first row of pins. Taking the first row of pins with 50 PIN feet as an example, the positive power supply occupies 1 PIN foot, the negative power supply occupies 1 PIN foot, and each vacuum equipment occupies 3 PIN feet, which are respectively used for vacuum pumping, vacuum breaking and vacuum signal feedback. Therefore, at most 16 vacuum equipment units can be assembled, that is, at most 16 bases 1 can be assembled between the first mounting seat 2 and the second mounting seat 3. When replacing with a first row of pins with more PIN feet, more bases 1 can be assembled between the first mounting seat 2 and the second mounting seat 3.

[0052] In this embodiment, a circuit board A11 is disposed in each of the bases 1. A first electrical signal socket 12, a second electrical signal socket 13, and a third electrical signal socket 14 that are electrically connected to the circuit board A11 are disposed on the base 1. Any two adjacent bases 1 are plugged and matched through the corresponding first electrical signal socket 12 and second electrical signal socket 13 to achieve electrical connection between the two adjacent bases 1. The first electrical signal socket 12 is a first row of pins, and the second electrical signal socket 13 is a first row of sockets. The plugging and matching of the first row of pins and the first row of sockets are used to replace the traditional wire harness connection. This structural design makes the electrical connection between the adjacent bases 1 more convenient. There is no need to straighten out the wire harness and then connect it to the corresponding end. Only need to insert the first row of pins into the first row of sockets. Moreover, this structure makes the overall structure of the installed base more compact and beautiful. In this embodiment, the base 1 is electrically connected to a vacuum device (i.e., a vacuum pump unit or a vacuum generator unit) through the third electrical signal socket 14. The third electrical signal socket 14 is a second row of pins or a second row of sockets. The corresponding vacuum pump unit or vacuum generator unit is provided with a second row of sockets or a second row of pins. In this embodiment, the third electrical signal socket 14 is a second row of sockets.

[0053] In this embodiment, as Figure 4 shown, a circuit board B21 is disposed in the first mounting base 2. A fourth electrical signal socket 22 that is electrically connected to the circuit board B21 is disposed on the first mounting base 2. The fourth electrical signal socket 22 is electrically connected to the first electrical signal socket 12 of the outermost base 1. A control box 4 is further included. The control box 4 is fixedly connected to the first mounting base 2. A circuit board C41 is disposed in the control box 4. A fifth electrical signal socket 42 that is electrically connected to the circuit board C41 is disposed on the control box 4. A sixth electrical signal socket 23 that is electrically connected to the fifth electrical signal socket 42 is further disposed on the first mounting base 2. The sixth electrical signal socket 23 is a first row of pins, and both the fourth electrical signal socket 22 and the fifth electrical signal socket 42 are first rows of sockets. The plugging and matching of the first row of pins and the first row of sockets are used to replace the traditional wire harness connection. This structural design makes the electrical connection between the control box 4 and the first mounting base 2, and between the first mounting base 2 and the outermost base 1 more convenient. There is no need to straighten out the wire harness and then connect it to the corresponding end. Only need to insert the first row of pins into the first row of sockets. Moreover, this structure makes the overall structure of the installed base for the valve island type vacuum device more compact and beautiful.

In this embodiment, as Figure 5 , Figure 6 and Figure 17 shown, the first confluence channel 6 and the second confluence channel 7 are arranged separately from each other. The first mounting seat 2 and / or the second mounting seat 3 are provided with a third air port 24 and a third air passage 25 for communicating the third air port 24 with the first confluence channel 6. A first air passage 17 communicating with the first air port 15 is provided inside the base 1.

A second air passage 18 communicating with the second air port 16 is provided inside the base 1. When a plurality of bases 1 are stacked, the positions of the second air passages 18 of the bases 1 correspond to each other and are communicated with each other, and jointly form a second confluence channel 7.

[0055] In this embodiment, as Figures 1 to 3As shown, when the base is used as the base of a vacuum generator system, the vacuum device is a vacuum generator unit at this time. The first confluence channel 6 is a positive pressure air source intake channel, and the second confluence channel 7 is an exhaust channel. A first air port 15 communicating with the positive pressure air source intake channel and a second air port 16 communicating with the exhaust channel are provided on the base 1. The positive pressure air source enters the positive pressure air source intake channel through the third air port 24 and the third air duct 25, and then enters each vacuum generator unit through the first air port 15; each vacuum generator unit communicates with the exhaust channel through the second air port 16, and the gas enters the exhaust channel through the second air port 16, then enters the fourth air port 26 through the fourth air duct 27, and is uniformly silenced and exhausted through the silencing device 9 provided at the fourth air port 26. When the base is used as the base of a vacuum pump system, the vacuum device is a vacuum pump unit at this time. The first confluence channel 6 is a positive pressure air source intake channel, and the second confluence channel 7 is a negative pressure air source intake channel. The negative pressure air source enters the negative pressure air source intake channel through the fifth air port 101 and the fifth air duct 102, and then enters each vacuum pump unit through the second air port 16; the positive pressure air source enters the positive pressure air source intake channel through the third air port 24 and the third air duct 25, and then enters each vacuum pump unit through the first air port 15.

[0056] As another preferred solution of the present invention, it further includes a cover plate 8 cooperating with the base 1. A first plug 81 corresponding to and cooperating with the first air port 15 and a second plug 82 corresponding to and cooperating with the second air port 16 are provided on the lower end surface of the cover plate 8. A first sealing ring 811 is provided between the first air port 15 and the first plug 81, and a second sealing ring 821 is provided between the second air port 16 and the second plug 82. In this embodiment, as Figure 3 and Figure 13 shown, the setting of the cover plate 8 facilitates the configuration of a spare base 1 to facilitate the customer to expand the externally connected vacuum device. The vacuum device is a vacuum generator unit or a vacuum pump unit. For example, in the case where N vacuum devices need to be used, N + 1 bases 1 are assembled between the first mounting seat 2 and the second mounting seat 3, and a cover plate 8 is installed on one of the bases 1. When the (N + 1)th base 1 needs to be enabled, only need to remove the cover plate 8 and plug the vacuum device onto the spare base 1. Of course, two or more spare bases 1 can also be set, that is, configure two or more bases 1 with cover plates 8. The first plug 81 is in sealing cooperation with the first air port 15, and the second plug 82 is in sealing cooperation with the second air port 16 to prevent air leakage in the spare base 1. The setting of the first sealing ring 811 increases the sealing performance between the first air port 15 and the first plug 81; the setting of the second sealing ring 821 increases the sealing performance between the second air port 16 and the second plug 82.

[0057] As another preferred embodiment of the present utility model, a third sealing ring 28 is provided between the first mounting seat 2 and the base 1, between adjacent bases 1, and between the base 1 and the second mounting seat 3. In this embodiment, as Figure 3 and Figure 16 shown, the provision of the third sealing ring 28 increases the sealing performance between the first mounting seat 2 and the base 1, between adjacent bases 1, and between the base 1 and the second mounting seat 3.

[0058] As another preferred embodiment of the present utility model, a silencing device 9 is provided at the fourth air port 26. A fourth sealing ring 29 is provided between the silencing device 9 and the fourth air port 26. In this embodiment, as Figure 3 shown, when the base is used as the base of a vacuum generator system, the first confluence channel 6 is a positive pressure air source intake channel, the second confluence channel 7 is an exhaust channel, and each vacuum generator unit is connected to the silencing device 9 via the exhaust channel. The silencing device 9 is used for unified silencing and exhaust, which is beneficial to reducing the noise generated during the operation of the vacuum generator. By adopting the unified exhaust method, each vacuum generator unit does not need to be additionally provided with a silencing device 9, which is beneficial to reducing the cost of the vacuum generator. The provision of the fourth sealing ring 29 increases the sealing performance between the silencing device 9 and the fourth air port 26.

[0059] As another preferred embodiment of the present utility model, a connection block 10 is provided at the fourth air port 26. The connection block 10 is provided with a fifth air port 101, and a fifth air channel 102 communicating the fifth air port 101 with the fourth air port 26 is provided inside the connection block 10. A fourth sealing ring 29 is provided between the connection block 10 and the fourth air port 26. In this embodiment, as Figure 16 shown, when the base is used as the base of a vacuum pump system, the first confluence channel 6 is a positive pressure air source intake channel, the second confluence channel 7 is a negative pressure air source intake channel, and the negative pressure air source enters the negative pressure air source intake channel through the fifth air port 101, and then enters each vacuum pump unit through the second air port 16. By uniformly introducing the negative pressure air source through the fifth air port 101 of the connection block 10, each vacuum pump unit does not need to be additionally provided with an intake assembly, which is beneficial to reducing the cost of the vacuum pump system. The provision of the fourth sealing ring 29 increases the sealing performance between the connection block 10 and the fourth air port 26.

[0060] Obviously, the above embodiments are merely examples for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. The obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
