[0023] In laser processing equipment, air inlets and exhaust outlets are usually required to maintain ventilation in the processing space for heat dissipation and dust removal; however, this can easily lead to light leakage at the air inlet, which not only causes laser energy loss but also can easily cause damage to external components of the processing equipment or personnel.

[0024] Based on the above considerations, this utility model proposes a laser processing equipment 100.

[0025] Please see Figure 1 , Figure 3 and Figure 5 In one embodiment of this utility model, the laser processing equipment 100 includes a frame 10, a laser head 20, and a light-blocking module 30. The frame 10 is provided with a processing space 111 and a first air inlet 112 and an exhaust outlet 113 communicating with the processing space 111. The first air inlet 112 and the exhaust outlet 113 are located on the side wall of the frame 10. The laser head 20 is disposed in the processing space 111. The light-blocking module 30 is disposed in the processing space 111 and is disposed opposite to the first air inlet 112. The light-blocking module 30 and the side wall provided with the first air inlet 112 form a tortuous air intake channel 33, and the air intake channel 33 is communicating with the first air inlet 112.

[0026] The laser processing equipment 100 proposed in this application is a device that uses laser as a medium to process workpieces. The laser processing methods include, but are not limited to, at least one of laser engraving, laser cutting, laser welding, laser marking, and laser cleaning.

[0027] The frame 10 serves as the supporting foundation for the laser processing equipment 100, used for installing and connecting other components of the laser processing equipment 100. The frame 10 includes a frame body 11 and a cover 12. The frame body 11 contains a processing space 111, and the processing space 111 contains a processing platform 13 for supporting workpieces. The processing space 111 communicates with the outside world through an opening on the frame 10. This opening allows workpieces to enter and exit the processing space 111, and also allows operators to disassemble, assemble, and maintain the components within the processing space 111. The cover 12 covers the opening of the frame body 11. The shape of the cover 12 roughly matches the shape of the opening, allowing the cover 12 to be rotatably connected to the frame body 11, enabling the cover 12 to be flipped up and down or left and right relative to the frame body 11 for opening and closing.

[0028] The laser head 20 is a module used to emit laser light to process workpieces. The laser head 20 can integrate a laser generator and a light guide structure, allowing it to generate laser light itself. In some embodiments, the laser generator can be set independently of the laser head 20, for example, in a laser host located outside the frame 10. The laser host and laser head 20 are connected via an optical cable. In this case, the laser head 20 emits the received laser light onto the workpiece to process it. Optionally, the laser head 20 can be fixed in the frame 10. The laser head 20 can be directed towards different areas of the workpiece for processing by moving the workpiece. Alternatively, a laser galvanometer can be installed in the laser head 20, and the laser beam deflection can be controlled by oscillating the galvanometer, thus directing the laser beam towards different areas of the workpiece for processing. Of course, in some embodiments, a moving component 80 can be provided in the laser processing equipment 100 to control the movement of the laser head 20, allowing it to move to different areas for processing. In some embodiments, the laser processing equipment 100 may also include a lifting assembly for controlling the lifting of the laser head 20, which can adjust the height of the laser head 20 and the laser focal point to process surfaces at different heights, and can also adjust the laser processing mode.

[0029] The side wall of the frame 10 is provided with a first air inlet 112 and an exhaust outlet 113 communicating with the processing space 111. The first air inlet 112 is used to allow outside air to flow into the processing space 111. The first air inlet 112 can be a single opening or include several small openings. For example, the side wall with the first air inlet 112 can be set as a grille or a perforated plate. The exhaust outlet 113 is used to discharge the airflow in the processing space 111 to the outside, thereby carrying away the waste gas, waste residue, dust, etc. generated during the laser processing. This can prevent waste gas, waste residue, and dust from remaining in the processing space 111 and causing optical path pollution and workpiece contamination. It also actively discharges the airflow in the processing space 111 for purification treatment to avoid environmental pollution. Optionally, an exhaust fan 42 can be provided at the exhaust outlet 113 to drive the airflow and improve the gas flow efficiency. Of course, a fan 50 can also be provided at the first air inlet 112, the processing space 111, or the second air inlet 114 in the following embodiment to drive the airflow.

[0030] In this embodiment, a light-blocking module 30 is provided in the laser processing equipment 100. The light-blocking module 30 is located on the air outlet side of the first air inlet 112 and forms an air intake channel 33 communicating with the first air inlet 112 with the side wall of the frame 10 where the first air inlet 112 is located. The air intake channel 33 is configured as a tortuous flow channel structure. With this configuration, external air can enter the processing space 111 through the first air inlet 112 and the air intake channel 33. Furthermore, due to the tortuous configuration of the air intake channel 33, the laser inside the laser processing equipment 100 cannot be directed towards the first air inlet 112 through the air intake channel 33, thereby achieving a good light-blocking effect. This improves the light leakage prevention performance of the laser processing equipment 100, reduces laser energy loss, and prevents external devices and personnel from being burned by the laser.

[0031] Optionally, the light-blocking module 30 can be configured as an integral structure, in which an air intake channel 33 is formed; the air intake channel 33 may include at least one of a curved channel, a bent channel, a spiral channel, and other types of channel structures. Alternatively, the light-blocking module 30 may also include at least two separate structures, for example, in the following embodiment, a first light-blocking plate 31 and a second light-blocking plate 32 are arranged side by side, such that the first air guide port 311 of the first light-blocking plate 31 and the second air guide port 321 of the second light-blocking plate 32 are staggered. In this case, the area between the side wall of the first air inlet 112 and the first light-blocking plate 31, the first air guide port 311, the area between the first light-blocking plate 31 and the second light-blocking plate 32, and the second air guide port 321 are sequentially connected to form a tortuous channel structure.

[0032] See also Figures 3 to 6In one embodiment, the light-blocking module 30 includes a first light-blocking plate 31 and a second light-blocking plate 32. The first light-blocking plate 31 is disposed opposite to the first air inlet 112 and has a first air guide 311. The second light-blocking plate 32 is disposed on the side of the first light-blocking plate 31 away from the first air inlet 112 and is spaced apart from the first light-blocking plate 31. The second light-blocking plate 32 has a second air guide 321. The second air guide 321 is offset from the first air guide 311 in the orthographic projection of the first light-blocking plate 31. The first air inlet 112, the first air guide 311, and the second air guide 321 are not on the same straight line. The area between the side wall of the first air inlet 112 and the first light-blocking plate 31, the first air guide 311, the area between the first light-blocking plate 31 and the second light-blocking plate 32, and the second air guide 321 are sequentially connected to form at least a partial air intake channel 33.

[0033] In this embodiment, the light-blocking module 30 includes a split first light-blocking plate 31 and a second light-blocking plate 32, located between the first air inlet 112 and the processing platform 13. The first light-blocking plate 31 has a first air guide 311, which can be positioned opposite to the first air inlet 112, or its projection onto the first light-blocking plate 31 can be offset from the first air guide 311. The second light-blocking plate 32 is located on the side of the first light-blocking plate 31 facing away from the first air inlet 112, and has a second air guide 321. The projection of the second air guide 321 onto the first light-blocking plate 31 is offset from the first air guide 311, and the first air inlet 112, the first air guide 311, and the second air guide 321 are not on the same straight line. In this configuration, when airflow flows from the first air inlet 112 to the light-blocking module 30, it passes through the first air guide 311 to the second baffle. However, due to the misalignment of the first air guide 311 and the second air guide 321, the airflow first flows along the second baffle to the second air guide 321, causing the airflow to flow in a tortuous manner, rather than directly passing through the first air guide 311 and then directly through the second air guide 321. Even if the laser in the processing space 111 is directed towards the second air guide 321, because the second air guide 321 and the first air guide 311 are misaligned, the laser will be blocked by the first baffle and will not then be directed towards the first air inlet 112. This effectively prevents light leakage, reduces laser energy loss, and avoids laser burns to external devices and personnel.

[0034] Alternatively, a connecting post can be provided on the second baffle to fix the second baffle to the side wall of the frame 10 or to the first baffle, so that the first baffle and the second baffle are spaced apart while the second baffle is installed; or the second baffle can include an air guide part and a bending part, the air guide part is recessed relative to the bending part away from the first baffle and is provided with a second air guide port 321, the bending part is connected to the frame 10 or the first baffle, so that the air guide part and the first baffle are spaced apart, which can also prevent the second baffle from blocking the first air guide port 311 and prevent the first baffle from blocking the second air guide port 321.

[0035] Optionally, the light-blocking module 30 may also include a third light-blocking plate or more light-blocking plates, each light-blocking plate being provided with an air duct for airflow, wherein the air ducts of at least two light-blocking plates are staggered relative to each other, or the air ducts of any two adjacent light-blocking plates may be staggered.

[0036] Optionally, in addition to setting the first light-blocking plate 31 and the second light-blocking plate 32, the light-blocking module 30 may also include other light-blocking structures with tortuous flow channels, which are not limited here.

[0037] Please see Figure 6 In one embodiment, the first light-blocking plate 31 is provided with a plurality of first air vents 311 arranged in an array; and / or, the second light-blocking plate 32 is provided with a plurality of second air vents 321 arranged in an array.

[0038] In this embodiment, by providing multiple first air vents 311 on the first light-blocking plate 31, the ventilation area on the first baffle plate can be increased to ensure the air intake; it also avoids the structural strength of the first light-blocking plate 31 being too low due to the excessively large opening area of ​​a single first air vent 311.

[0039] Similarly, by setting multiple second air inlets 321 on the second light-blocking plate 32, the ventilation area on the second light-blocking plate can be increased to ensure the air intake; it also avoids the structural strength of the second light-blocking plate 32 being too low due to the excessively large opening area of ​​a single second air inlet 321.

[0040] Please see Figure 2 In one embodiment, the laser processing equipment 100 further includes an exhaust module 40, which includes a mounting bracket 41 and an exhaust fan 42. The mounting bracket 41 is disposed in the processing space 111; the exhaust fan 42 is fixed to the mounting bracket 41 and is disposed toward the exhaust port 113.

[0041] In this embodiment, the laser processing equipment 100 is equipped with an exhaust module 40, which includes an exhaust fan 42 and a mounting bracket 41 for fixing the exhaust fan 42. The mounting bracket 41 is positioned near the exhaust port 113, and the exhaust fan 42 is opposite to the exhaust port 113. The exhaust fan 42 can be spaced apart from the exhaust port 113, or it can be located within the exhaust port 113. This arrangement allows the exhaust fan 42 to drive the gas flow in the processing space 111, directing the airflow towards the exhaust port 113 and then outwards. This improves the airflow rate and exhaust speed, ensuring timely removal of waste gas from the processing space 111 and reducing the risk of contaminating the optical path and workpiece.

[0042] Please see Figure 2 , Figure 3 as well as Figure 10 In one embodiment, the frame 10 is provided with a second air inlet 114, which is located on two opposite side walls of the frame 10, and an exhaust port 113 is located on the other side wall of the frame 10. The mounting bracket 41 is located on the side of the processing space 111 near the second air inlet 114 and is opposite to the second air inlet 114. The exhaust fan 42 is fixed to the side of the mounting bracket 41 near the exhaust port 113. The mounting bracket 41 is provided with a third air guide port 413, and the orthographic projection of the second air inlet 114 on the mounting bracket 41 is offset from the third air guide port 413.

[0043] In this embodiment, a second air inlet 114 is also provided on the frame 10. The first air inlet 112 and the second air inlet 114 are respectively located on two opposite side walls of the frame 10. Both the first air inlet 112 and the second air inlet 114 are used to allow external airflow into the processing space 111, which can increase the air intake volume, better drive the exhaust gas in the processing space 111 to the location of the exhaust port 113, and also help improve heat dissipation efficiency. The second air inlet 114 can be a single opening or include several small openings. For example, the side wall with the second air inlet 114 can be set as a grille or a perforated plate.

[0044] The mounting bracket 41 is positioned opposite the side wall where the second air inlet 114 is located, and a third air guide 413 is provided on the mounting bracket 41. This misalignment of the orthographic projection of the second air inlet 114 onto the mounting bracket 41 with the third air guide 413 ensures that the airflow from the second air inlet 114 into the processing space 111 is not affected, and also prevents laser light directed towards the third air guide 413 from being directed towards the second air inlet 114 and escaping outwards. In other words, the mounting bracket 41 can act as a light-blocking element at the second air inlet 114, thus preventing light leakage at the second air inlet 114. This also eliminates the need for other light-blocking structures, simplifying the number of components in the laser processing equipment 100.

[0045] See also Figure 1 and Figure 3 In one embodiment, the opening area of ​​the first air inlet 112 is larger than the opening area of ​​the second air inlet 114.

[0046] In this embodiment, the opening area of ​​the second air inlet 114 refers to the area of ​​all air intake regions on the side wall where the second air inlet 114 is located. For example, the second air inlet 114 includes several small openings, and the opening area of ​​the second air inlet 114 is the total area of ​​all the small openings. Similarly, the opening area of ​​the first air inlet 112 refers to the area of ​​all air intake regions on the side wall of the first air inlet 112. For example, the first air inlet 112 includes several small openings, and the opening area of ​​the second air inlet 114 is the total area of ​​all the small openings. The opening area of ​​the first air inlet 112 is made larger than the opening area of ​​the second air inlet 114, thereby increasing the air intake volume of the first air inlet 112 compared to the second air inlet 114.

[0047] In this embodiment, the exhaust fan 42 is fixed on the mounting bracket 41 near the second air inlet 114, and the first air inlet 112 and the second air inlet 114 are located on opposite sides of the processing platform 13; that is, the distance between the exhaust fan 42 and the first air inlet 112 is relatively far, and the first air inlet 112 is also closer to the processing platform 13. By setting a larger air intake volume for the first air inlet 112, it is beneficial to drive the exhaust gas near the first air inlet 112 to the exhaust port 113, ensuring the ventilation effect. Optionally, the opening area size and ratio of the first air inlet 112 and the second air inlet 114 can be set according to the air intake volume requirements on both sides. For example, the air intake volume of the first air inlet 112 can account for about 70% of the total air intake volume, and the air intake volume of the second air inlet 114 can account for about 30% of the total air intake volume; of course, other air volume ratios can also be set.

[0048] Please see Figure 9 In one embodiment, the laser processing equipment 100 further includes a fan 50, which is disposed in the processing space 111 and is disposed opposite to the second air inlet 114. The fan 50 is used to drive the external airflow into the processing space 111 along the second air inlet 114.

[0049] In this embodiment, a fan 50 is provided on the side where the second air inlet 114 is located. The fan 50 can be used to drive the external airflow from the second air inlet 114 into the processing space 111, which is beneficial to increase the airflow efficiency, ensure the air intake volume, and also prevent the phenomenon of airflow being discharged from the second air inlet 114, ensuring that the processing space 111 has sufficient air intake, and also preventing exhaust gas from leaking from the second air inlet 114.

[0050] See also Figure 3 and Figure 9In one embodiment, the laser processing equipment 100 further includes a main control board 60, which is disposed on the side of the mounting bracket 41 facing the second air inlet 114 and is disposed opposite to the second air inlet 114.

[0051] In this embodiment, the main control board 60 of the laser processing equipment 100 is positioned on the side of the mounting bracket 41 facing the second air inlet 114. This arrangement ensures that the airflow entering the processing space 111 from the second air inlet 114 first passes through the main control board 60, which helps cool the main control board 60, improves its heat dissipation efficiency, and prevents overheating. Optionally, the main control board 60 can be mounted on the mounting bracket 41 or on the frame 10.

[0052] Optionally, the main control board 60 and the mounting bracket 41 can be spaced apart to form an airflow channel between the main control board 60 and the mounting bracket 41. This allows airflow to flow through the back of the main control board 60, increasing the heat dissipation area of ​​the main control board 60. It also allows airflow to flow along the airflow channel to the third air guide hole and the fourth air guide hole in the following embodiment.

[0053] In some embodiments, the laser processing equipment 100 also includes a fan 50 disposed on the side of the second air inlet facing the main control board 60, which can increase the airflow velocity to improve the heat dissipation efficiency of the main control board 60.

[0054] Please see Figure 10 In one embodiment, the mounting bracket 41 is further provided with a fourth air duct 414. The fourth air duct 414 and the third air duct 413 are respectively located at both ends of the mounting bracket 41. The orthographic projection of the second air inlet 114 on the mounting bracket 41 is offset from the fourth air duct 414.

[0055] In this embodiment, a third air inlet 413 and a fourth air inlet 414 are respectively provided at both ends of the mounting bracket 41. The orthographic projection of the second air inlet 114 on the mounting bracket 41 is offset from both the third air inlet 413 and the fourth air inlet 414. Part of the airflow flowing into the processing space 111 from the second air inlet 114 flows to the third air inlet 413 and the other part flows to the fourth air inlet 414, thereby flowing into one side of the processing platform 13 from both ends of the mounting bracket 41, increasing the amount of air that can pass through the mounting bracket 41, avoiding the large wind resistance caused by the setting of the mounting bracket 41, and facilitating the uniform flow of airflow in the processing space 111.

[0056] See also Figure 2 and Figure 10In one embodiment, the mounting bracket 41 includes a first bracket 411 and a second bracket 412 connected to each other. The first bracket 411 is disposed opposite to the second air inlet 114, and a third air guide port 413 is provided at the end of the first bracket 411 away from the second bracket 412. The second bracket 412 is provided with a mounting hole 415 and a fourth air guide port 414. The mounting hole 415 is disposed opposite to the exhaust port 113, and the exhaust fan 42 is fixed in the mounting hole 415. The fourth air guide port 414 is located below the mounting hole 415.

[0057] In this embodiment, the mounting bracket 41 includes a first bracket 411 and a second bracket 412 connected together. The first bracket 411 is spaced between the processing platform 13 and the second air inlet 114, and a third air guide port 413 is provided at the end of the first bracket 411 away from the exhaust port 113. The second bracket 412 is set at an angle to the first bracket 411, and the second bracket 412 is opposite to the exhaust port 113 and is provided with a mounting hole 415 opposite to the exhaust port 113. The exhaust fan 42 is installed in the mounting hole 415. The second bracket 412 is also provided with a fourth air guide port 414, which is located below the mounting hole 415. This arrangement can not only meet the installation requirements of the exhaust fan 42, but also reduce the mutual influence between the airflow flowing through the fourth air guide port 414 and the airflow discharged from the exhaust fan 42, thus avoiding airflow short-circuiting.

[0058] Please see Figure 7 , Figure 8 as well as Figure 11 In one embodiment, the laser processing equipment 100 further includes an air guide module 70, which includes a fixed sleeve 71, a sealing element 72, and a smoke exhaust pipe 73. It is located on the outside of the frame 10 and is disposed opposite to the exhaust port 113. At least part of the sealing element 72 is disposed inside the fixed sleeve 71 and is arranged around the exhaust port 113 in a circumferential manner. One end of the smoke exhaust pipe 73 is sandwiched between the sealing element 72 and the fixed sleeve 71.

[0059] In this embodiment, the laser processing equipment 100 further includes an exhaust pipe 73 for discharging waste gas. The exhaust pipe 73 is connected to the outside of the exhaust port 113 and is fixed by a fixing sleeve 71 and a sealing element 72. The fixing sleeve 71 can be connected to any of the frame 10, the exhaust fan 42, and the mounting bracket 41. Both ends of the fixing sleeve 71 are open. At least a portion of the sealing element 72 is disposed within the fixing sleeve 71 and is arranged circumferentially around the exhaust port 113. One end of the exhaust pipe 73 is inserted into the fixing sleeve 71 and sandwiched between the outer wall of the sealing element 72 and the inner wall of the fixing sleeve 71. The sealing element 72 can be made of, but is not limited to, silicone, rubber, or silicone rubber. The sealing element 72 is elastic and can deform to better fit the exhaust pipe 73, thereby achieving a good sealing effect and preventing air leakage due to gaps between the sealing element 72 and the exhaust pipe 73. The exhaust pipe 73 can guide the exhaust gas to a suitable location, such as connecting the exhaust outlet of the exhaust pipe 73 to the purification module, so that the exhaust gas is introduced into the purification module, purified and filtered, and then discharged to the outside.

[0060] Please see Figure 11 In one embodiment, the sealing member 72 includes a first sealing part 721 and a second sealing part 722. The first sealing part 721 is disposed on the side of the fixed sleeve 71 facing the frame 10 and is arranged around the exhaust port 113. The second sealing part 722 is connected to the inner edge of the first sealing part 721 and is disposed inside the fixed sleeve 71. The second sealing part 722 is arranged around the exhaust port 113. One end of the exhaust pipe 73 is clamped between the second sealing part 722 and the fixed sleeve 71.

[0061] In this embodiment, the first sealing portion 721 of the seal 72 is located on the side of the fixing sleeve 71 facing the frame 10. The side of the first sealing portion 721 facing away from the fixing bracket can be connected to any of the frame 10, the exhaust fan 42, and the mounting bracket 41. For example, the fixing sleeve 71 is connected to the exhaust fan 42 and fixed together with the exhaust fan 42 on the mounting bracket 41, and the first sealing portion 721 can be sandwiched between the fixing sleeve 71 and the exhaust fan 42; or, the fixing sleeve 71 is mounted on the frame 10, so that the first sealing portion 721 is sandwiched between the fixing sleeve 71 and the outer side wall of the frame 10. This arrangement allows the first sealing portion 721 to provide a seal between the end face of the fixing sleeve 71 and the surface on which the fixing sleeve 71 is mounted, preventing air leakage between the end face of the fixing sleeve 71 and the surface on which the fixing sleeve 71 is mounted. The second sealing part 722 of the sealing element 72 is inserted into the fixed sleeve 71 and is used to cooperate with the fixed sleeve 71 to clamp the exhaust pipe 73.

[0062] Please see Figure 7 , Figure 8 as well as Figure 11In one embodiment, the inner wall of the fixed sleeve 71 is provided with a plurality of limiting parts arranged side by side along the axial direction, and the exhaust pipe 73 is inserted into one end of the fixed sleeve 71 and is provided with a corrugated section, and the pleated part 731 of the corrugated section is engaged between two adjacent limiting parts.

[0063] In this embodiment, the limiting portion provided in the fixing sleeve 71 can be a closed-loop rib arranged around the circumference of the exhaust pipe 73, or it can be a rib extending partially around the circumference of the exhaust pipe 73; no limitation is made here. A limiting region is formed between two adjacent limiting portions along the axial direction of the fixing sleeve 71.

[0064] Meanwhile, the exhaust pipe 73 is inserted into one end of the fixed sleeve 71 and is provided with a corrugated section. The corrugated section includes multiple pleats 731 arranged along the length of the exhaust pipe 73, so that some of the pleats 731 are confined in the limiting area between two limiting parts. This can limit the exhaust pipe 73 along the length of the exhaust pipe 73, prevent the exhaust pipe 73 from detaching from the fixed sleeve, and improve the installation stability.

[0065] Please see Figure 11 In one embodiment, the exhaust pipe 73 is configured as a corrugated pipe.

[0066] This design allows the exhaust pipe 73 to have a certain degree of flexibility, enabling it to bend and be easily pulled to a suitable position. At the same time, it also allows the exhaust pipe 73 to be telescopically adjustable to suit different usage environments.

[0067] Please see Figure 2 In one embodiment, the laser processing equipment 100 further includes a moving component 80 for driving the laser head 20 to translate.

[0068] The moving component 80 can be used to drive the laser head 20 to move back and forth in one direction, or it can drive the laser head 20 to move in different directions as in the following embodiment.

[0069] For example, the moving component 80 includes a first slide rail 81 and a second slide rail 82. The first slide rail 81 is disposed in the processing space 111. The second slide rail 82 is slidably disposed on the first slide rail 81. The length direction of the second slide rail 82 intersects the length direction of the first slide rail 81. The laser head 20 is slidably disposed on the second slide rail 82.

[0070] In this embodiment, the laser head 20 can slide along the second slide rail 82 or along the first slide rail 81, thereby giving the laser head 20 a larger range of motion, allowing it to move to more areas for laser processing and improving processing flexibility. The first slide rail 81 can be configured as an optical axis, guide rail, or similar structure, and the second slide rail 82 can also be configured as an optical axis, guide rail, or similar structure. Furthermore, the laser processing equipment 100 also includes a first driving component for driving the second slide rail 82 to slide along the first slide rail 81, and a second driving component for driving the laser head 20 to slide along the second slide rail 82. The first driving component and the second driving component can be configured as a motor lead screw assembly, a synchronous belt assembly, or similar components, and are not limited here.

[0071] In one embodiment, the laser processing equipment 100 further includes a lifting assembly, which is in transmission cooperation with the laser head 20 to drive the laser head 20 to move up and down. This configuration allows the height of the laser head 20 and the laser focal point to be adjusted via the lifting assembly, enabling processing of surfaces at different heights, and also allowing for adjustment of the laser processing method.

[0072] Optionally, the lifting assembly can be configured as a motor lead screw assembly, a timing belt assembly, a cylinder or electric cylinder pushing assembly, etc., and there is no limitation here.
