[0002] In the field of machinery, tilting doors are often hinged to the main unit of equipment such as optical inspection equipment, semiconductor processing equipment, and non-standard equipment in processing production lines. The main unit has an opening, and the tilting door can rotate relative to the main unit to either the open or closed position.

Detailed Implementation

[0054] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0055] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected" and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0056] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0057] In related technologies, some mechanical equipment is equipped with a flip-up door. Most flip-up doors are L-shaped or approximately L-shaped, and have two parts that fit together at an angle. This allows the flip-up door to simultaneously cover the openings on both sides of the main equipment when closed. For example, if the flip-up door is the front upper door of the equipment, it can be flipped upwards to open or downwards to close. When closed, part of the flip-up door is located on the upper side of the main equipment, and part is located on the front side of the main equipment.

[0058] Typically, a support mechanism is needed between the tilting door and the main unit of the equipment to support the tilting door and keep it in the open position. A gas spring is one type of support mechanism; in some technologies, a gas spring is installed between the tilting door and the main unit to support the tilting door and keep it in the open position.

[0059] The force value of a gas spring mainly refers to its spring force, that is, the elastic force that a nitrogen gas spring can generate under specific conditions (such as temperature, inflation pressure, etc.). The larger the gas spring force value, the greater the supporting force for the tilting door. The nominal value of a gas spring, also known as the standard force value, refers to the spring force of the gas spring under standard conditions. It is the maximum force that the gas spring can withstand under standard conditions. The nominal value is an important indicator of the gas spring's performance and directly relates to its effectiveness and safety in practical applications. In the manufacturing process of mechanical equipment, gas springs with the same nominal value are generally purchased uniformly. However, the actual force value of a gas spring usually has a tolerance compared to its nominal value.

[0060] However, the inventors discovered that even if the same batch of gas springs are used in the production of the same batch of mechanical equipment, the actual force value of the gas spring may differ from the nominal force value. This can lead to inconsistencies in the opening angle and height of the flip doors after they are opened, affecting the structural and performance consistency of the mechanical equipment. Figure 19 This illustrates situations where the opening angle and height of a flip-top door vary after different mechanical equipment has been assembled, such as... Figure 19The diagram illustrates that a tilting door 20 is installed on the main unit 10. The tilting door 20 includes a first door body 21 and a second door body 22 that are angled together. The first door body 21 is rotatably mounted on the main unit 10. However, if the actual force values ​​of the gas springs differ, even if the tilting doors 20 of different mechanical devices can be supported in the open position by the gas springs, the opening angle of some tilting doors 20 may be too small (e.g., Figure 19 (α' is a diagram) The door opening height is too small (e.g.) Figure 19 (h1 is shown in the diagram), and some flip doors 20 have an excessively large opening angle (such as...). Figure 19 (α symbol) and the door opening height is too large (e.g.) Figure 19 (h2 diagram).

[0061] To address the problems associated with using gas springs as a support mechanism, the inventors considered the following approach: Multiple mounting positions would be provided on both the main unit and the tilting door. During assembly, after installing the gas springs, operators would conduct a door-opening test to determine if the opening angle or height of the tilting door met the requirements. If not, the operator would disassemble the entire gas spring or remove only one end, reinstall it in another position, and repeat the test until the opening angle or height of the tilting door met the requirements. However, this gas spring assembly and adjustment method was time-consuming, resulting in high overall assembly costs for the mechanical equipment and limited adjustment accuracy.

[0062] To address the problems associated with using gas springs as a support mechanism, the inventors also considered directly sliding one end of the gas spring onto the main unit of the equipment or the flip door. However, when the flip door is in the open position, it is easy for an external object to touch the flip door, causing the end of the gas spring to slide and displace, making it difficult to maintain the current opening angle stably. This is unsafe during the application of mechanical equipment.

[0063] Based on this, this application provides a mechanical device with a flip door, and provides a new assembly method between the gas spring, the main unit of the device and the flip door. During the process of adjusting the opening angle and opening height of the flip door, it is easy to adjust the supporting force of the gas spring on the flip door. The adjustment operation of the gas spring is simple, convenient and not cumbersome.

[0064] The position of the first end of the gas spring on the main unit of the equipment can be steplessly adjusted, and / or the position of the second end of the gas spring on the tilting door can be steplessly adjusted, so that the operator can adjust the position of at least one end of the gas spring according to actual needs, thereby adjusting the opening angle and opening height of the tilting door and improving the consistency of opening height and opening angle of tilting doors of different mechanical equipment.

[0065] Please refer to the following. Figures 1 to 18 This application describes the mechanical device with a flip-up door.

[0066] The mechanical equipment with a flip door includes the main unit 10, the flip door 20, and the gas spring 30.

[0067] Figure 3 , Figure 7 , Figure 9 , Figure 10 The diagram illustrates some components of a mechanical device with a flip door, mainly used to show the cooperation relationship between the main unit 10, the flip door 20, and the gas spring 30. Figure 1 , Figure 2 A partial schematic diagram of a mechanical device with a flip-up door is shown. Figure 1 This indicates that the flip door 20 is in the open position. Figure 2 This indicates that the flip door 20 is in the closed position. Figure 18 The diagram also shows the tilting door 20 in the closed position, but the gas spring 30 is not shown; only the interaction between the tilting door 20 and the main unit 10 is illustrated. For ease of understanding, some accompanying drawings indicate the y-direction and z-direction, two mutually perpendicular directions, to aid in understanding the positional relationships between different components. In some embodiments, the y-direction is the horizontal direction of the device (e.g., the front-to-back direction), and the z-direction is the vertical direction of the device (also known as the up-and-down direction).

[0068] The machinery and equipment can be testing equipment, semiconductor processing equipment, etc. Testing equipment can be, but is not limited to, automated optical inspection equipment (AOI equipment, AOI stands for Automated Optical Inspection), and semiconductor processing equipment can be, but is not limited to, SMT placement equipment.

[0069] The main unit 10 of the equipment has an opening, which facilitates the operator's inspection, maintenance, or replacement of parts inside the equipment. In some equipment, there is a working chamber inside, and the opening provides a channel for the input and output of target objects, such as items to be processed or tested. The flip door 20 is rotatably mounted on the main unit 10 of the equipment. The flip door 20 can be opened or closed by rotation. During normal operation of the equipment, the flip door 20 is closed to prevent dust from entering the equipment.

[0070] A gas spring 30 is installed between the main equipment 10 and the tilting door 20. The gas spring 30 serves as a support mechanism for the tilting door 20 when it is in the open position, keeping the tilting door 20 in the open position and thus keeping the opening of the main equipment 10 open for convenient maintenance, parts replacement, and material feeding / discharging operations. The gas spring 30 is a liquid supply accessory that can provide support, buffering, braking, height adjustment, and angle adjustment. It consists of a pressure cylinder, piston rod 31, piston, sealing guide sleeve, and filling material (inert gas or oil-gas mixture).

[0071] The main unit 10 of the equipment is provided with a first mounting part 13. The first mounting part 13 can be an integrally formed part on the main unit 10 of the equipment, or it can be a component fixed to the main unit 10 by means of screws, welding, or other methods. The first mounting part 13 is used to provide a mounting position for the gas spring 30.

[0072] The flip door 20 includes a first door body 21 and a second door body 22. The first door body 21 and the second door body 22 are angled and connected to each other. For example, the first door body 21 and the second door body 22 are set at approximately 90 degrees. By rotatably mounting the first door body 21 to the device host 10, the flip door 20 can rotate relative to the device host 10, allowing the flip door 20 to be adjusted between an open position and a closed position. In this application, openings are provided on both adjacent sides of the device host 10 to make the openings of the device host 10 approximately L-shaped, and a corresponding approximately L-shaped flip door 20 structure is adopted. This allows more of the internal space of the device to be exposed through a larger opening when the flip door 20 is open, making it more practical. The flip door 20 is provided with a second mounting part 23. The second mounting part 23 can be an integrally formed part of the flip door 20, or it can be a component fixed to the flip door 20 by means of screws, welding, etc. The second mounting part 23 is used to provide a mounting position for the gas spring 30.

[0073] Reference Figure 1 , Figure 3 , Figure 4 , Figures 7 to 13 The first end of the gas spring 30 is mounted on the first mounting part 13 of the main unit 10, and the second end is mounted on the second mounting part 23 of the tilting door 20. (See reference...) Figures 10 to 12 The first end of the gas spring 30 is hinged to the first mounting part 13 via the first connecting shaft 40, allowing the first end of the gas spring 30 to rotate relative to the first mounting part 13, thus achieving a rotatable engagement between the gas spring 30 and the main unit 10 of the equipment. The second end of the gas spring 30 is hinged to the second mounting part 23 via the second connecting shaft 60, allowing the second end of the gas spring to rotate relative to the second mounting part 23, thus achieving a rotatable engagement between the gas spring 30 and the flip door 20. When the flip door 20 rotates relative to the main unit 10 for opening or closing operations, the first end of the gas spring 30 will rotate relative to the main unit 10, and the second end of the gas spring 30 will rotate relative to the flip door 20, ensuring that the opening and closing process is smooth and unobstructed by the gas spring 30.

[0074] To address the aforementioned issue where the actual force value of the gas spring 30 differs from its nominal value, resulting in discrepancies between the actual opening angle and the designed opening angle of the tilting door 20 after assembly, and between the actual opening height and the designed opening height, the gas spring 30 of the mechanical equipment in this application is configured such that the mounting position of at least one end is adjustable, and this adjustment is stepless. The gas spring 30 can be configured in at least three ways.

[0075] One configuration of the gas spring 30 is as follows: the installation position of the first end of the gas spring 30 on the main unit 10 of the equipment can be infinitely adjusted, while the installation position of the second end of the gas spring 30 on the flip door 20 is either not adjustable or can only be adjusted in steps.

[0076] The second configuration of the gas spring 30: the installation position of the second end of the gas spring 30 on the flip door 20 can be infinitely adjusted, while the installation position of the first end of the gas spring 30 on the flip door 20 can be either not adjusted or can only be adjusted in steps.

[0077] The third configuration of the gas spring 30: the installation position of the first end of the gas spring 30 on the main unit 10 of the equipment can be infinitely adjusted, and the installation position of the second end of the gas spring 30 on the flip door 20 can be infinitely adjusted.

[0078] The mounting position of the first end of the gas spring 30 on the main unit 10 of the equipment can be steplessly adjusted, which is achieved in the following way:

[0079] The first mounting part 13 is provided with a first mounting hole 131, which is an adjustment hole. The first mounting hole 131 is elongated to allow the first connecting shaft 40 to be fixed in different positions within the first mounting hole 131. The mechanical device also includes a first locking member 50. The first end of the gas spring 30 is rotatably connected to the first connecting shaft 40, which passes through the first mounting hole 131. The first locking member 50 is used to fix the first connecting shaft 40 in any position within the first mounting hole 131. When the first connecting shaft 40 is fixed in different positions within the first mounting hole 131, the gas spring 30 is used to support the flip door 20 in different opening positions.

[0080] In other words, the first mounting hole 131 is an extended hole-type structure, with a dimension d1 in its extending direction and a diameter d2 for the first connecting shaft 40, where d1 > d2 (e.g., d1 ≥ 2d2). The first connecting shaft 40 can be locked in multiple positions within the first mounting hole 131. Alternatively, the first mounting hole 131 has multiple mounting positions, with adjacent mounting positions directly connected or connected via a transition structure. The first locking member 50 is used to fix the first connecting shaft 40 to any mounting position within the first mounting hole 131.

[0081] The mounting position of the second end of the gas spring 30 on the main unit 10 of the equipment can be steplessly adjusted, which is achieved in the following way:

[0082] The second mounting part 23 is provided with a second mounting hole 231, which is an adjustment hole. The second mounting hole 231 is elongated to allow the second connecting shaft 60 to be fixed in different positions within the second mounting hole 231. The mechanical device also includes a second locking member. The second end of the gas spring 30 is rotatably connected to the second connecting shaft 60, which passes through the second mounting hole 231. The second locking member is used to fix the second connecting shaft 60 in any position within the second mounting hole 231. When the second connecting shaft 60 is fixed in different positions within the second mounting hole 231, the gas spring 30 is used to support the tilting door 20 in different opening positions.

[0083] In other words, the second mounting hole 231 is an extended hole structure with a dimension d3 in its extension direction and a diameter d4 for the second connecting shaft 60, where d3 > d4 (e.g., d3 ≥ 2d4). The second connecting shaft 60 can be locked in multiple positions within the second mounting hole 231. Alternatively, the second mounting hole 231 has multiple mounting positions, with adjacent mounting positions directly connected or connected via a transition structure. The second locking element is used to fix the second connecting shaft 60 to any mounting position within the second mounting hole 231.

[0084] Understandably, when the flip door 20 is in the open position, the greater the supporting force exerted by the gas spring 30 on the flip door 20, the greater the opening angle of the flip door 20 when it is held in a stable open position under the support of the gas spring 30. Similarly, the smaller the supporting force exerted by the gas spring 30 on the flip door 20, the smaller the opening angle of the flip door 20 when it is held in a stable open position under the support of the gas spring 30.

[0085] In this application, the connecting shaft at at least one end of the gas spring 30 is installed in an adjustable mounting hole. Through the cooperation of the adjustable mounting hole, the corresponding locking member, and the corresponding connecting shaft, the connecting shaft at the end of the gas spring 30 can be locked in any position within the adjustable mounting hole by the locking member, realizing stepless adjustment of the fixed position of the connecting shaft, thereby realizing stepless adjustment of the position of the end of the gas spring 30, realizing adjustment of the tilt angle of the gas spring 30, and further realizing adjustment of the supporting force of the gas spring 30 on the tilt door 20 when it is opened, realizing adjustment of the opening angle and opening height of the tilt door 20. In other words, in this application, the installation position of at least one end of the gas spring 30 is steplessly adjustable. By adjusting the installation position of the gas spring 30, the opening angle and height of the tilt door 20 can be adjusted to meet the opening accuracy requirements of the tilt door 20.

[0086] Understandably, after the gas spring 30 is installed and adjusted, and the opening angle and height of the tilting door 20 meet the requirements, the locking mechanism is tightened. During normal operation of the equipment, the first end of the gas spring 30 is fixed on the main unit 10, and the first connecting shaft 40 will not slide within the first mounting hole 131. The second end of the gas spring 30 is fixed on the tilting door 20, and the second connecting shaft 60 will not slide within the second mounting hole 231. This ensures that the gas spring 30 provides consistent support to the tilting door 20, keeping the force on the tilting door 20 stable during opening. The tilting door 20 can be stably maintained in the open position with the support of the gas spring 30, preventing accidental closure of the tilting door 20 and causing injury to personnel or materials, thus ensuring high safety performance.

[0087] Compared to the scheme where multiple first mounting holes 131 are provided in the first mounting part 13 and multiple second mounting holes 231 are provided in the second mounting part 23, so that the installation position of both ends of the gas spring 30 can be adjusted in stages, the scheme of this application can fix the first connecting shaft 40 of the first end of the gas spring 30 to any position in the first mounting hole 131 by the first locking member 50, or fix the second connecting shaft 60 of the second end of the gas spring 30 to any position in the second mounting hole 231 by the second locking member. This can achieve stepless adjustment of the gas spring 30. The stepless adjustment method can steplessly adjust the supporting force of the gas spring 30 on the flip door 20, thereby making the difference in the opening force and opening support force of the gas spring 30 on the flip door 20 of each device smaller and the consistency of the mechanical equipment higher.

[0088] If a scheme is adopted where multiple first mounting holes 131 are provided in the first mounting part 13 and multiple second mounting holes 231 are provided in the second mounting part 23, allowing the gas spring 30 to be adjusted in stages at both ends, the operator needs to repeatedly disassemble and reinstall the gas spring 30 to another mounting position when adjusting it. This is cumbersome, requires frequent changes to the connecting shaft position, and is time-consuming, resulting in high time and labor costs. The solution proposed in this application simplifies the adjustment process of the gas spring 30 and reduces costs. Taking the adjustment of the first connecting shaft 40 position by the first locking member 50 as an example, it is only necessary to unlock the first locking member 50, then move the first connecting shaft 40 to the appropriate position within the first mounting hole 131, and then lock the first locking member 50. The adjustment of the second connecting shaft 60 position by the second locking member is similar.

[0089] The assembly and adjustment scheme of the gas spring 30 in this application can reduce the requirements for the nominal value tolerance of the gas spring 30, reduce the requirements for the difference between the actual force value and the nominal value of the gas spring 30 to a certain extent, reduce the accuracy requirements of the gas spring 30, and reduce material procurement costs and operation and maintenance costs.

[0090] In one embodiment, the mechanical equipment is an AOI (Optical Inspection) device, which is a device that detects common defects encountered in welding production based on optical principles. The main unit 10 has openings on its upper and front sides, and the flip door 20 is an upward-opening flip door (also called an upward-opening door). When the mechanical equipment is placed on the ground, such as... Figure 1 , Figure 9 The diagram illustrates that the tilting door 20 can be tilted upwards from the closed position to the open position. After the user operates the tilting door 20 away from the closed position, it can tilt towards the open position under the elastic force of the gas spring 30. When the tilting door 20 is open and stable, it is in the open position. When the tilting door 20 is in the open position, the gas spring 30 supports the tilting door 20 to keep it in the open position. In mechanical equipment, using an upward-tilting door 20 can reduce the space occupied by the equipment on its left and right sides.

[0091] Optionally, the flip door 20 has an L-shaped or near-L-shaped door structure. The L-shaped flip door offers excellent adaptability to various operating conditions in AOI equipment: First, the L-shaped flip door design makes internal components easier to expose, facilitating maintenance and replacement by personnel; second, when opened, the L-shaped flip door flips upwards and sits above the main unit 10, without occupying additional horizontal space, which is advantageous for AOI equipment installation environments with limited space.

[0092] In one embodiment, the gas spring 30 is a nitrogen spring 30, which refers to a gas spring 30 in which the inert gas filled in the pressure cylinder is high-pressure nitrogen, and the spring function is achieved by utilizing the reaction force of nitrogen. The nitrogen spring 30 is safe and reliable.

[0093] In one embodiment, the gas spring 30 is a free-moving gas spring 30. The free-moving gas spring 30 has two working positions: shortest and longest. The gas spring 30 cannot stop automatically during its extension and retraction stroke. Using a free-moving gas spring 30 simplifies the opening and closing of the tilting door 20, eliminating the need for other sensing and control elements to stop the gas spring 30 during its stroke. This results in a simple structure and low cost. Furthermore, the connecting shaft at at least one end of the gas spring 30 can be fixed at any position in the adjustable mounting hole, allowing for stepless adjustment of the gas spring 30's mounting angle. This enables adjustments to the support effect of the free-moving gas spring 30 on the tilting door 20 when it is in its longest working position, and also meets the requirement for consistency in the opening angle and height of the tilting door 20 in mechanical equipment.

[0094] In one embodiment, the main unit 10 is connected to a side panel 12 and a top panel 11. The top panel 11 has a first opening 101, the side panel 12 has a second opening 102, and the top panel 11 has a second opening 102. The first opening 101 and the second opening 102 are connected. Figure 1 The diagram shows that the side panel 12 and the top panel 11 enclose the inner cavity of the equipment body, which is used to easily accommodate other parts (such as electronic components) or to hold items to be processed or tested.

[0095] Optionally, the main unit 10 of the equipment also includes a base plate, and openings are provided at the top and bottom of the top of the side plate 12. The top plate 11 is provided on the top of the side plate 12 and only covers a part of the opening at the top of the side plate 12, so as to leave the first opening 101 on the top side of the equipment body. The base plate is provided at the bottom of the side plate 12.

[0096] like Figure 3 , Figure 6 , Figure 9 As shown, the end of the first door 21 facing away from the second door 22 is rotatably connected to the top plate 11 via a door mounting bracket 90; the tilting door 20 can rotate between the open and closed positions. For example... Figure 1 , Figure 9 As shown, when the flip door 20 is in the open position, the first door body 21 leaves one opening, and the second door body 22 leaves the second opening 102. (Example) Figure 2 , Figure 18 As shown, when the flip door 20 is in the closed position, the first door body 21 covers the first opening 101, and the second door body 22 covers the second opening 102.

[0097] A gas spring 30 is disposed between the side panel 12 and the first door 21. A first mounting part 13 is disposed on the side panel 12, and a second mounting part 23 is disposed on the first door 21. Thus, the first end of the gas spring 30 is mounted on the side panel 12, and the second end is mounted on the first door 21. When the flip door 20 is in the open position, the first door 21 and the plane containing the first opening 101 are angled to expose the first opening 101, and the gas spring 30 supports the first door 21.

[0098] Optionally, the machine side panel 12 includes a first side panel 121, and a second opening 102 is disposed on the first side panel 121. The machine side panel 12 also includes two mounting side panels 122 located on opposite sides of the first opening 101 and the top panel 11. For example, the flip door 20 is an upward-opening door. When the mechanical equipment is in use, the first opening 101 is located on the upper side of the equipment, the second opening 102 is located on the front side of the equipment, and the two mounting side panels 122 are located on the left and right sides of the equipment, respectively. When the flip door 20 is in the closed position, the first door body 21 covers the upper side of the equipment, and the second door body 22 covers the front side of the equipment. Figure 1As shown, gas springs 30 are provided on both the left and right sides of the first door body 21, and second mounting parts 23 for mounting the second ends of the gas springs 30 are provided on the left and right sides of the first door body 21. The first end of the gas spring 30 on the left side is mounted on the mounting side plate 122 on the left side, and the first end of the gas spring 30 on the right side is mounted on the mounting side plate 122 on the right side.

[0099] In this embodiment, the first end of the gas spring 30 is installed on the side plate 12. Firstly, this eliminates the need for a transverse beam passing through the inner cavity of the equipment body to provide a mounting position for the first end of the gas spring 30, saving internal space and reducing interference between the gas spring 30 and other internal components of the main unit 10. Secondly, it allows for better and more stable support of the first door 21 from both sides. In this embodiment, the second end of the gas spring 30 is installed on the first door 21 instead of the second door 22. When the flip door 20 is open, the gas spring 30 can apply support force to the first door 21 instead of the second door 22, thus more stably and reliably keeping the flip door 20 in the open position and preventing the gas spring 30 from jamming during the opening and closing of the flip door 20.

[0100] In one embodiment, the flip door 20 is an upward-opening flip door 20. When the flip door 20 is in the closed position, the first door body 21 is located on the upper side of the main unit 10, and the second door body 22 is located on the front side of the main unit 10. The first end of the gas spring 30 is mounted on the side plate 12, and the second end is mounted on the first door body 21. (Referring to...) Figure 9 When the flip door 20 is in the open position, the gas spring 30 tilts upward and backward from its first end to its second end. Compared with the scheme where the gas spring 30 is installed at both ends in other positions, in this embodiment, the gas spring 30 can use its thrust to push the first door body 21 upward and backward during the opening process of the flip door 20, and finally reliably hold the first door body 21 in the open position. In this embodiment, the setting angle and end installation position of the gas spring 30 are reasonable, which can smoothly support the flip door 20 to the open position with minimal space occupation, and stably support and hold the flip door 20 in the open position.

[0101] The inventors considered setting many fixing holes in the first mounting part 13 and the second mounting part 23 to accommodate the force tolerance range of the gas spring 30. However, during the assembly of the whole machine, the uncertainty of the force value makes it impossible to make fine adjustments. During debugging, it is often necessary to repeatedly adapt the mounting positions of the two ends of the gas spring 30 to different fixing holes. Operators often do not know whether to adjust the position of the first end or the second end of the gas spring 30, nor do they know which direction to adjust the position of the gas spring 30 end. This makes the operation of gas spring 30 installation and adjustment difficult and inefficient.

[0102] To address the cumbersome adjustment process of the force value of the gas spring 30 to the opening position of the tilting door 20, in one embodiment, the gas spring 30 is configured such that the position of its first end is infinitely adjustable, while the position of its second end is fixed. This means that after the gas spring 30 is installed in the mechanical equipment, if an opening test reveals that the final opening angle or height of the tilting door 20 does not meet requirements, only the position of the first end needs to be adjusted during the installation and adjustment of the gas spring 30; the position of the second end does not need to be adjusted.

[0103] The gas spring 30 has an adjustable first end: a first mounting part 13 has a first mounting hole 131, and the mechanical device also includes a first locking member 50, which is used to fix the first connecting shaft 40, which is rotatably connected to the first end of the gas spring 30, at any position within the first mounting hole 131. The gas spring 30 has a fixed second end: a second mounting part 23 has a second mounting hole 231, and the mechanical device also includes a second locking member, which is used to fix the second connecting shaft 60, which is rotatably connected to the second end of the gas spring 30, within the second mounting hole 231. The position of the second connecting shaft 60 within the second mounting hole 231 is not adjustable, and the external dimensions of the second connecting shaft 60 match the shape of the second mounting hole 231. Both the first and second ends of the gas spring 30 are rotatable.

[0104] Thus, when the opening angle or opening height does not meet the requirements, during the installation and debugging of the gas spring 30, it is only necessary to simply unlock the first locking part 50 without completely disassembling it, so that the first connecting shaft 40 can move within the first mounting hole 131. When the operator adjusts the position of the first connecting shaft 40, the position of the first end of the gas spring 30 is adjusted simultaneously until the opening angle and opening height meet the requirements and the force balance point is reached (that is, the actual force of the gas spring 30 can support and hold the flip door 20 in the target opening position). Then, the first locking part 50 is locked to complete the debugging.

[0105] In this embodiment, the improvements to the installation method and conditions of the gas spring 30 achieve the following effects:

[0106] First, when adjusting the gas spring 30, the position of the second end of the gas spring 30 is fixed, and only the position of the first end of the gas spring 30 needs to be adjusted. This stepless adjustment on one side makes it clearer for operators how to adjust the installation position of the gas spring 30, simplifying operation and avoiding confusion. Second, the second connecting shaft 60 connected to the second end of the gas spring 30 fits well with the second mounting hole 231. The second mounting part 23 provides good support for the second end of the gas spring 30, ensuring a stable connection and allowing the gas spring 30 to more stably support the tilting door 20. Third, when adjusting the gas spring 30, it is not necessary to completely pull the connecting shaft hinged to the end of the gas spring 30 out of the mounting hole, nor is it necessary to reinsert the connecting shaft into the mounting hole, making operation simpler and more time-saving. Fourth, the position of the first connecting shaft 40 within the first mounting hole 131 is steplessly adjustable, resulting in higher adjustment precision and easier adjustment without the need for repeated attempts. Fifth, the first mounting hole 131 is provided on the first mounting part 13 of the main unit 10 as a mounting hole that allows the position of the first connecting shaft 40 to be adjusted. In this way, it is not necessary to set the first mounting part 13, which may occupy a certain space, in the first door body 21, so that the first door body 21 can maintain a thinner thickness and avoid affecting the aesthetics of the first door body 21.

[0107] In one embodiment, the first mounting part 13 is provided with a first mounting hole 131, and the mechanical device further includes a first locking member 50, which is used to fix the first connecting shaft 40 at any position within the first mounting hole 131; when the first connecting shaft 40 is fixed at different positions in the first mounting hole 131, the gas spring 30 is used to support the flip door 20 at different opening positions. Here, the flip door 20 being at different opening positions means that the included angle between the first door body 21 and the plane containing the first opening 101 is different; such as... Figure 19 As shown in the diagram, the solid line indicating the flip door 20 and the dashed line indicating the flip door 20 are at different angles to the plane S1 where the first opening 101 is located. At this time, the opening angle α and the opening height h of the flip door 20 are different.

[0108] Based on this, the two ends of the first mounting hole 131 are a first hole end 1311 and a second hole end 1312, respectively. The first mounting hole 131 is an elongated hole extending from the first hole end 1311 to the second hole end 1312, so that the mounting position of the first connecting shaft 40 on the side plate 12 of the main unit 10 can be adjusted. The first mounting hole 131 can be configured in at least the following ways:

[0109] One configuration method for the first mounting hole 131: such as Figure 15 , Figure 16To illustrate, in the height direction of the mechanical equipment, the end of the first hole 1311 is closer to the first opening 101 than the end of the second hole 1312; in the horizontal direction of the mechanical equipment, the end of the second hole 1312 is closer to the second mounting part 23 than the end of the first hole 1311. Furthermore, the first mounting hole 131 is an arc-shaped hole. When the flip door 20 is in the open position, the center of the arc of the first mounting hole 131 is located on the side of the first mounting hole 131 closest to the second mounting part 23. In other words, the side of the first mounting hole 131 closest to the second mounting part 23 is a concave portion, and the side away from the second mounting part 23 is a convex portion.

[0110] Optionally, when the flip door 20 is in the open position, it follows an arc-shaped trajectory centered on the rotation axis of the second connecting shaft 60 and passing through the first mounting hole 131, passing through the first hole end 1311 and the second hole end 1312 of the first mounting hole 131 (e.g., ...). Figure 15 , Figure 16 (Example of a dashed arc trajectory in the image).

[0111] The second configuration method for the first mounting hole 131: (e.g.) Figure 17 The mounting hole 131' is illustrated in the diagram. In the height direction of the mechanical equipment, the end of the first hole 1311 is close to the first opening 101 relative to the end of the second hole 1312; in the horizontal direction of the mechanical equipment, the end of the second hole 1312 is close to the second mounting portion 23 relative to the end of the first hole 1311. Furthermore, the first mounting hole 131 is a straight hole. Exemplarily, the first mounting hole 131 is a straight, angled hole extending downward and backward from the end of the first hole 1311 to the end of the second hole 1312.

[0112] The third configuration method for the first mounting hole 131: (e.g.) Figure 17 The first mounting hole 131 extends along the height direction.

[0113] Fourth configuration method for the first mounting hole 131: (e.g.) Figure 17 The first mounting hole 131 extends along the height direction.

[0114] It is understandable that when the flip door 20 is in the closed position, the main unit 10 of the equipment will support the flip door 20, and there will be no accident caused by the flip door 20 falling and failing. The configuration of the gas spring 30 is mainly to ensure that when the flip door 20 is in the open position, it can stably support the flip door 20 in the target open position.

[0115] Below, taking one configuration of the first mounting hole 131 as an example, we will analyze the force state of the flip door 20 when it is in the open position:

[0116] If the actual force value of the gas spring 30 is greater than the nominal value of the gas spring 30, the actual opening angle of the flip door 20 may be greater than the target opening angle. In this case, the first end of the gas spring 30 needs to be adjusted upward and towards the end 1311 of the first hole so that the upward supporting force of the gas spring 30 on the first door body 21 is reduced, thereby allowing the gas spring 30 to apply a smaller supporting force to the flip door 20 and reduce the opening angle of the flip door 20.

[0117] If the actual force value of the gas spring 30 is less than the nominal value of the gas spring 30, the actual opening angle of the flip door 20 may be less than the target opening angle. In this case, the first end of the gas spring 30 needs to be adjusted downward and towards the end of the second hole 1312 so that the upward supporting force of the gas spring 30 on the first door body 21 can be increased, thereby allowing the gas spring 30 to apply a greater supporting force to the flip door 20 and increase the opening angle of the flip door 20.

[0118] Therefore, when adjusting the gas spring 30, operators can clearly know the position of the first end of the gas spring 30 to be adjusted, and also know in which direction the first end of the gas spring 30 should be adjusted. The adjustment operation is clear, easy to understand, and highly efficient, greatly reducing debugging time and costs. For mechanical equipment, it can ensure assembly consistency and door opening height consistency.

[0119] Reference Figure 15 Point O is the upper fixed point of the first end of gas spring 30, and point T0 is the lower fixed point when the force of gas spring 30 is the nominal value F. Since the force value of gas spring 30 has a tolerance range during manufacturing, it is tentatively set to F±a, meaning the actual force value may be between Fa and F+a. To ensure a consistent door opening height (with point O remaining stationary), when the actual force value of gas spring 30 differs, we need to adjust the position of its first end (i.e., adjust the position of its lower fixed point):

[0120] ① When gas spring 30 is supplied with material, the actual force value is the maximum force value, i.e., F+a. In order to ensure that the vertical component of the gas spring 30 is reduced, from Figure 15 It can be seen that moving the position of the first end (lower fixed point) of the gas spring 30 upward will reduce the vertical component of the force used to support the tilting door 20 upward. Therefore, we need to move the first end (lower fixed point) upward. Assume that the first end (lower fixed point) of the gas spring 30 is T1 at this point, and ∠A1OT1 is α1; according to the sine theorem for right triangles: SINα1=G(equivalent weight of the entire door frame) / F+a.

[0121] ② Similarly, when the gas spring is 30mm thick, the actual force value is at its minimum, i.e., Fa, and ∠A2OT2 is α2. According to the sine theorem of a right triangle: SINα2=G(equivalent weight of the entire door frame) / Fa.

[0122] According to the sine principle, when the angle is less than 90 degrees, the larger the sine value, the closer the angle is to 90 degrees. This also confirms the descriptions in ① and ② above: when the actual force value of the gas spring 30 is greater than the nominal value, we need to move the first end (lower fixed point) of the gas spring 30 upwards; conversely, we move the first end (lower fixed point) of the gas spring 30 downwards. Based on the actual G and F and their tolerance values, we can define this radian angle range. Figure 15 In the diagram, L1, L0, and L2 can be used to indicate the magnitude of the supporting force that the gas spring 30 can exert on the first door body 21 when the first end (lower fixed point) of the gas spring 30 is located at points T1, T0, and T2, respectively.

[0123] Understandably, the difference between one configuration of the first mounting hole 131 and another configuration of the first mounting hole 131 lies only in whether the first mounting hole 131 is an arc-shaped hole or a straight hole. When the first mounting hole 131 is an arc-shaped hole, when the second connecting shaft 60 at the second end of the gas spring 30 moves to different positions within the first mounting hole 131, it can better achieve stepless change of the supporting force, and the arc-shaped hole can better support the second connecting shaft 60.

[0124] In addition, compared with the third and fourth configurations of the first mounting hole 131, the configuration of the first mounting hole 131 has the following advantages: after the position of the first end of the gas spring 30 is adjusted to a suitable position and the first locking member 50 is locked, the wall of the first mounting hole 131 can provide more upward support force to the first connecting shaft 40, so that the positions of both ends of the gas spring 30 can be stably fixed in the desired position; and, in the process of adjusting the position of the first connecting shaft 40 in the first mounting hole 131, it is easier to achieve stepless adjustment of the gradual increase and decrease of the support force.

[0125] In one embodiment, reference is made to Figure 3 , Figure 5 The second mounting portion 23 is provided with a plurality of second mounting holes 231, which are spaced apart from the side opposite to the second door body 22 to the side close to the second door body 22. The second locking member is used to fix the second connecting shaft 60 to any of the second mounting holes 231. It is understood that, generally, if the opening angle and opening height of the flip door 20 do not meet the requirements, the position of the second connecting shaft 60 at the second end of the gas spring 30 does not need to be adjusted. However, the second mounting portion 23, with its multiple mounting holes, provides a larger adjustment range for the gas spring 30, meeting the requirements of more usage scenarios and offering greater versatility. Furthermore, the second mounting portion 23 is more versatile; for example, for flip doors 20 of different sizes and weights, the second end of the gas spring 30 can be mounted in different second mounting holes 231.

[0126] In other embodiments, the second mounting part 23 may also be provided with only one second mounting hole 231.

[0127] In one embodiment, the first mounting part 13 is an independent component, and it is mounted to the device host 10 by means of screws, welding, or other methods. Thus, the first mounting part 13 and the device host 10 can be made of different materials to meet their different performance and cost requirements. Furthermore, the first mounting hole 131 does not need to be directly provided on the device host 10, avoiding affecting the integrity and aesthetic appearance of the device host 10.

[0128] Optionally, the first mounting part 13 is a sheet metal component.

[0129] Optionally, refer to Figure 4 , Figure 13 The first mounting part 13 includes a first mounting plate 132 and a first connecting plate 133. The first mounting plate 132 is spaced apart from the mounting side plate 122 of the machine side plate 12, and the first mounting plate 132 is connected to the mounting side plate 122 of the machine side plate 12 through the first connecting plate 133. A first mounting hole 131 is provided in the first mounting plate 132, and the first mounting hole 131 can be, but is not limited to, an arc-shaped hole. The first locking member 50 is used to fix the first connecting shaft 40 at any position in the first mounting hole 131. When the first connecting shaft 40 is fixed in different positions in the first mounting hole 131, the gas spring 30 is used to support the flip door 20 in different opening positions.

[0130] The first end of the gas spring 30 is located on the side of the first mounting plate 132 opposite to the mounting side plate 122 of the machine side plate 12. The first locking member 50 is disposed between the first mounting plate 132 and the mounting side plate 122 of the machine side plate 12. One end of the first connecting shaft 40 is connected to the first end of the gas spring 30, and the other end is connected to the first locking member 50. It can be understood that the space between the first mounting plate 132 and the mounting side plate 122 of the machine side plate 12 provides an operating space 14, which allows the user to reach into the operating hole with their hand or a tool to lock or unlock the first locking member 50.

[0131] Optionally, the first mounting part 13 is located inside the mounting side plate 122, so that when viewed from the outside of the main unit 10, neither the first mounting part 13, the first mounting hole 131, nor the first locking part 50 can be seen, resulting in an aesthetically pleasing appearance.

[0132] Optionally, refer to Figure 13 The first connecting plate 133 is provided with a first clearance opening 1331, which facilitates the insertion of the first clearance opening 1331 into the operating space 14 to unlock or lock the first locking member 50.

[0133] In one embodiment, the mechanical device with a flip door includes at least two gas springs 30, with one gas spring 30 disposed between each mounting side plate 122 and the first door body 21; a first mounting part 13 is fixed to the side of each mounting side plate 122 closest to the other mounting side plate 122. The two gas springs 30 support the flip door 20 from both sides, providing more stable support for the flip door 20 during opening, and the gas springs 30 do not occupy the middle of the first opening 101 and the second opening 102, thus not affecting the inspection or material feeding / exit of the main equipment 10 when the door is open.

[0134] In one embodiment, the gas spring 30 includes a cylinder 32 and a piston rod 31. The first end of the gas spring 30 is located at the end of the piston rod 31 opposite to the cylinder 32; that is, the end of the piston rod 31 is mounted on the side plate 12. The second end of the gas spring 30 is located at the end of the cylinder 32 opposite to the piston rod 31; that is, the end of the cylinder 32 is mounted on the tilting door 20. Thus, when the tilting door 20 is in the open position, the piston rod 31 of the gas spring 30 is located below the cylinder 32. When the piston rod 31 is below, the friction between the piston rod 31 and the cylinder 32 is relatively reduced due to gravity, which helps to extend the service life of the gas spring 30. The piston rod 31 being below helps to maintain the stability of the internal pressure of the gas spring 30, thereby improving the damping effect and making the gas spring 30 perform better in terms of support and cushioning. With the piston rod 31 installed downwards, the gas spring 30 can better absorb and disperse impact forces, providing more effective cushioning protection.

[0135] In one embodiment, the first end of the gas spring 30 is assembled to the first mounting portion 13 in the following manner:

[0136] Reference Figure 11 The gas spring 30 has a first ball head seat 33 at its first end, a first connecting shaft 40 is a first ball head bolt, and a first locking member 50 is a first locking nut. The first ball head bolt includes a first ball head body 41 and a first screw 42. The first ball head body 41 is connected to the first screw 42 and is rotatably mounted in the first ball head seat 33. The first ball head body 41 and the first locking nut are located on opposite sides of the first mounting portion 13. The first screw 42 passes through the first mounting hole 131 and is threadedly connected to the first locking nut. The first end of the gas spring 30 is rotatable relative to the first connecting shaft 40, and the first connecting shaft 40 is fixed in the first mounting hole 131 by the first locking nut. Optionally, the first ball head bolt also includes a first limiting protrusion 43 protruding outward from the outer circumference of the first screw 42.

[0137] By providing a first ball head seat 33 at the first end of the gas spring 30 and correspondingly using a first ball head bolt as the first connecting shaft 40, even when the first connecting shaft 40 is fixed to the first mounting hole 131 of the first mounting part 13 by the first locking member 50, the first end of the gas spring 30 can still rotate relative to the first mounting part 13. Thus, the first end of the gas spring 30 can be fixed in position but rotatable. Furthermore, the first limiting protrusion 43 added to the first ball head bolt can cooperate with the first locking nut to clamp both sides of the first mounting part 13. This ensures that while fixing the position of the first connecting shaft 40, it does not interfere with the rotation of the first ball head seat 33 relative to the first ball head body 41, thus balancing the positional fixation of the first connecting shaft 40 with the rotational effect of the first ball head seat 33.

[0138] In one embodiment, the second end of the gas spring 30 is assembled to the second mounting portion 23 in the following manner:

[0139] Reference Figure 12 The second end of the gas spring 30 is provided with a second ball head seat 34, the second connecting shaft 60 is a second ball head bolt (the structure of the second ball head bolt is not fully shown in the figure), and the second locking element is a second locking nut. The second ball head bolt includes a second ball head body and a second screw. The second ball head body is connected to the second screw and is rotatably mounted in the second ball head seat 34. The second ball head body and the second locking nut are located on opposite sides of the second mounting part 23. The second screw passes through the second mounting hole 231 and is threadedly connected to the second locking nut. The second end of the gas spring 30 can rotate relative to the second connecting shaft 60, and the second connecting shaft 60 is fixed in the second mounting hole 231 by the second locking nut. Optionally, the second ball head bolt also includes a second limiting protrusion protruding outward from the outer circumference of the second screw.

[0140] By providing a second ball head seat 34 at the second end of the gas spring 30 and correspondingly using a second ball head bolt as the second connecting shaft 60, even when the second connecting shaft 60 is fixed to the second mounting hole 231 of the second mounting part 23 by the second locking member, the second end of the gas spring 30 can still rotate relative to the second mounting part 23. Thus, the second end of the gas spring 30 can be fixed in position but rotatable. Furthermore, the second limiting protrusion added to the second ball head bolt can cooperate with the second locking nut to clamp both sides of the second mounting part 23. This ensures that while fixing the position of the second connecting shaft 60, it does not interfere with the rotation of the second ball head seat 34 relative to the second ball head body, thus balancing the positional fixation of the second connecting shaft 60 with the rotational effect of the second ball head seat 34.
