Description

Technical Field

[0001] This application belongs to the field of fixture technology, and more specifically, relates to a cleaning fixture. Background Technology

[0002] Flip-chip products have high precision requirements, and their production process is greatly affected by panel tolerances. Therefore, the design uses fewer circuit boards per panel to ensure component mounting accuracy. After the surface mount technology soldering process is completed, the flux and other impurities on the bottom of the surface mount devices need to be cleaned.

[0003] In related technologies, equipment spraying water is used for cleaning. However, this method sprays water directly onto the surface of the surface-mount device, making it difficult to effectively rinse the solder joints. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning fixture to solve the technical problem that the soldering positions of surface-mount devices are difficult to clean effectively in the prior art.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a cleaning fixture is provided, the cleaning fixture includes a housing, a cavity is provided inside the housing, an opening communicating with the cavity is provided at one end of the housing, and an inclined groove is provided on the side wall of the cavity, the length direction of the inclined groove is inclined to the height direction of the housing, and the inclined groove is used for inserting the side of the plate to be cleaned.

[0006] Optionally, the cavity has two opposite sidewalls respectively provided with inclined grooves, the inclined grooves are arranged in pairs, and the two inclined grooves of each pair are directly opposite each other on the two opposite sidewalls.

[0007] Optionally, multiple inclined slots are provided, and the multiple inclined slots are arranged at intervals along the length direction of the shell.

[0008] Optionally, the angle of inclination of the chute relative to the height direction ranges from 30° to 60°.

[0009] Optionally, the inclination angle of the chute is 45°.

[0010] Optionally, the shell has openings at opposite ends along the height direction, and the two openings are interconnected.

[0011] Optionally, the inclined groove extends from one end face of the housing in the height direction toward the opposite end, and the inclined groove forms a slot on the end face of the housing. The cleaning fixture also includes a frame adapted to be installed at one end of the housing, and the frame closes the slot of the inclined groove.

[0012] Optionally, the cleaning fixture also includes a locking element for securing the frame to the housing, the locking element being mounted on the housing.

[0013] Optionally, two rotating buckles are provided, and the locking element includes a rotating rod rotatably mounted on the housing. The rotating rod is provided with a pressure block adapted to press against the frame, and the frame is provided with a clearance opening corresponding to the position of the rotating rod.

[0014] Optionally, the opening of the inclined groove is flared.

[0015] The beneficial effects of the cleaning fixture provided in this application are as follows: Compared with the prior art, the cleaning fixture of this application, by setting a housing and setting an inclined groove in the cavity of the housing, and because the inclined groove is set at an angle on the housing, the plate to be cleaned is inserted into the inclined groove, so that the plate to be cleaned is also in an inclined state in the cleaning fixture. The cleaning liquid sprayed from the spray head of the cleaning equipment, under the action of water pressure and the rotation of the spray head, the angle of the cleaning liquid sprayed from the nozzle is at a certain angle with the central axis of the spray head.

Detailed Implementation

[0024] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0025] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0026] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0028] Flip-chip products have high precision requirements, and their production process is greatly affected by panel tolerances. Therefore, the design uses fewer circuit boards per panel to ensure component mounting accuracy. After the surface mount technology soldering process is completed, the flux and other impurities on the bottom of the surface mount devices need to be cleaned.

[0029] In related technologies, cleaning is carried out by spraying water with cleaning equipment. However, in this method, the cleaning liquid sprayed from the spray head of the cleaning equipment is at a certain angle to the central axis of the spray head under the action of water pressure and the rotation of the spray head. Since the cleaning fixture is placed horizontally, and general circuit boards can only be placed horizontally, the spray water is sprayed directly onto the surface of the surface-mount device during cleaning, and the solder joints are difficult to be effectively cleaned.

[0030] Please refer to the following: Figures 1 to 5 The cleaning fixture 100 provided in the embodiments of this application will now be described. The cleaning fixture 100 includes a housing 10, a cavity 11 is provided inside the housing 10, an opening 12 communicating with the cavity 11 is provided at one end of the housing 10, and an inclined groove 13 is provided on the side wall of the cavity 11. The length direction of the inclined groove 13 is inclined to the height direction of the housing 10, and the inclined groove 13 is used for inserting the side of the plate 200 to be cleaned.

[0031] The housing 10 has a cavity 11, and an opening 12 is provided at one end of the housing 10 and communicates with the cavity 11, so that the liquid sprayed from the spray head can enter the cavity 11 through the opening 12 to clean the plate 200 to be cleaned inside the cavity 11. The plate 200 to be cleaned can be a panel (a substrate that combines multiple circuit boards together), with multiple circuit boards assembled on the panel; the plate 200 to be cleaned can also be a printed circuit board.

[0032] The opening 12 of the housing 10 can be open or semi-open; there can be one or more openings 12; when there is one opening 12, the liquid sprayed from the spray head enters the cavity 11 through the opening 12, and an outlet can also be provided at the end of the cavity 11 away from the opening 12 so that the cleaning liquid can flow out; when there are two openings 12, they can be opposite openings 12 on the housing 10, or they can be two adjacent openings 12 on the housing 10.

[0033] An inclined groove 13 is formed on the side wall of the cavity 11, the length direction of the inclined groove 13 refers to the extension direction of the inclined groove 13 itself; the height direction of the housing 10 is the height direction of the housing 10 when it is placed in the cleaning equipment to be cleaned; such as Figure 1 As shown, the length direction of the inclined groove 13 is inclined to the height direction of the housing 10, and the inclination angle can be 30 degrees, 45 degrees, or 60 degrees. The design of the inclined groove 13 can be adjusted according to the different sizes and shapes of the plates to be cleaned 200 to adapt to different layouts of the plates to be cleaned 200.

[0034] The side of the board to be cleaned 200 can be inserted into the inclined groove 13, so that the board to be cleaned 200 is also tilted in the cleaning fixture 100. The cleaning fluid can more easily impact the bottom of the flip chip and its solder joint on the circuit board according to the predetermined path, and can better rinse the soldering position. Since the cleaning fluid can directly act on the soldering position, it can rinse away the flux and other impurities in the flip chip to the maximum extent, and the cleaning effect is good.

[0035] When the plate to be cleaned 200 is inserted into the inclined groove 13 of the housing 10, the plate to be cleaned 200 is tilted in the height direction of the housing 10. The path of water flow along the surface of the plate to be cleaned 200 will also change. Compared with horizontal placement, the cleaning liquid and other media are more likely to slide off the plate to be cleaned 200, reducing the drying time and reducing the risk of corrosion caused by moisture residue, thereby further improving the cleaning efficiency.

[0036] Effective cleaning can prevent problems such as corrosion and electromigration caused by flux and other impurities, thereby improving the long-term stability and reliability of circuit boards, especially flip-chip products.

[0037] Compared with the prior art, the cleaning fixture 100 provided in this application embodiment has a housing 10 and an inclined groove 13 in the cavity 11 of the housing 10. Since the inclined groove 13 is inclined on the housing 10, the plate to be cleaned 200 is inserted into the inclined groove 13, so that the plate to be cleaned 200 is also inclined in the cleaning fixture 100. The cleaning liquid sprayed from the spray head of the cleaning equipment is sprayed at an angle with the central axis of the spray head under the action of water pressure and the rotation of the spray head. The cleaning liquid is more likely to directly impact the bottom of the flip chip and its solder joints according to the predetermined path. It can better clean the soldering position and prevent corrosion, electromigration and other problems caused by flux and other impurities, thereby improving the reliability and service life of the product.

[0038] Please refer to some embodiments of this application. Figure 3 The cavity 11 has two opposite side walls with inclined grooves 13. The inclined grooves 13 are arranged in pairs, with the two inclined grooves 13 of each pair facing each other on the two opposite side walls.

[0039] The two sidewalls of the cavity 11 can be two opposite sidewalls along the length direction or two opposite sidewalls along the width direction. In one embodiment, such as Figure 3 Two inclined grooves 13 are provided on the two side walls of the cavity 11 along the width direction. The inclined grooves 13 are arranged in pairs so that both sides of the plate to be cleaned 200 can be inserted into the inclined grooves 13. By setting two opposing inclined grooves 13, a clear positioning point can be provided for the plate to be cleaned 200, ensuring that the plate to be cleaned 200 is placed at a consistent angle and position each time, thus ensuring the consistency of cleaning.

[0040] When the plate to be cleaned 200 is inserted into the two opposing inclined slots 13, the supports on both sides provide better stability and balance, preventing the plate to be cleaned 200 from moving or shifting due to water flow impact or other vibrations during the cleaning process, ensuring a smooth cleaning process. At the same time, the simple inclined slot design 13 makes the installation and removal of the plate to be cleaned 200 more convenient, improving work efficiency.

[0041] In another embodiment of this application, please refer to Figures 1 to 3 Multiple inclined grooves 13 are provided, and the multiple inclined grooves 13 are arranged at intervals along the length direction of the shell 10.

[0042] The inclined grooves 13 are all opened along the sidewalls of the cavity 11 in the width direction, so multiple inclined grooves 13 can be opened along the length direction of the cavity 11 at intervals. That is, multiple plates 200 to be cleaned can be placed simultaneously in the same cleaning fixture 100, which improves the overall efficiency of the cleaning process. Figure 3 By rationally arranging multiple inclined grooves 13, the internal space of the cleaning fixture 100 can be maximized, ensuring that as many plates 200 as possible can be processed in each cleaning operation. The evenly spaced multiple inclined grooves 13 also ensure that all plates 200 can obtain a relatively uniform cleaning effect.

[0043] In addition, in one embodiment, multiple spaced inclined grooves 13 are provided on the two opposite side walls of the cavity 11, and the inclined grooves 13 are arranged in pairs. When multiple plates 200 to be cleaned are inserted into different corresponding inclined grooves 13, each plate 200 to be cleaned can be well supported and fixed, preventing movement or collision during the cleaning process, and ensuring the safety and stability of the cleaning process.

[0044] In another embodiment, such as Figure 3 The cleaning fixture 100 can hold 11 panels at a time, with 5 circuit boards assembled on each panel. In the cleaning device, the cleaning frame can hold 8 cleaning fixtures 100 at a time, cleaning a total of 440 circuit boards, which improves cleaning efficiency and ensures cleaning effect.

[0045] In another embodiment of this application, see [reference] Figure 1 and Figure 2 The angle of inclination of the inclined groove 13 relative to the height direction ranges from 30° to 60°.

[0046] It should be noted that if the tilt angle of the board 200 to be cleaned is too small, the cleaning fluid may not be able to effectively reach the target area, while if the angle is too large, the water flow may be too concentrated, resulting in uneven cleaning. In this embodiment, the tilt angle of the inclined groove 13 relative to the height direction of the housing 10 is set to 30° to 60°. This range provides a balance point that ensures good rinsing effect while avoiding damage to the circuit board.

[0047] If set to 60°, the angle of the sloping groove 13 is steeper, which is suitable for rapid drainage, quickly removing loose impurities and accelerating the drying process; if set to 30°, the angle of the sloping groove 13 is gentler, which is suitable for fine cleaning, increases contact time, helps dissolve and remove stubborn contaminants, and ensures that even the smallest stains are removed.

[0048] In another embodiment of this application, the inclination angle of the sloping groove 13 is 45°.

[0049] By setting the tilt angle of the inclined groove 13 relative to the height direction of the housing 10 to 45°, the 45° angle provides a good balance. On the one hand, gravity can help the liquid flow better along the surface of the circuit board, so that the cleaning fluid can be distributed more evenly on the surface of the circuit board, ensuring that the cleaning fluid fully contacts all areas that need to be cleaned, including hard-to-reach places such as the bottom of flip chips and soldering positions, without neglecting some areas due to the angle being too large or too small. On the other hand, the direction and speed of the water flow are also strong enough to effectively flush away contaminants and drain the liquid faster, but without putting excessive pressure on the components on the circuit board.

[0050] The 45° angle of the inclined groove 13 can more effectively utilize gravity to help the liquid flow away quickly, reducing the possibility of water accumulation and residue. This reduces the time the cleaning fluid stays on the circuit board, lowering the risk of secondary contamination caused by residual liquid, such as corrosion or other chemical reactions. It is suitable for more than 200 types of contaminants on the board to be cleaned, effectively removing both larger particles and fine flux residues through appropriate water flow speed and direction, thus improving the efficiency of the entire cleaning process.

[0051] In another embodiment of this application, the housing 10 has openings 12 at both opposite ends along the height direction, and the two openings 12 are interconnected.

[0052] like Figure 3 The two end faces of the housing 10 with the largest area relative to the height of the housing 10 are provided with openings 12, which facilitates the liquid flushed out by the spray head to enter the cavity 11 and better clean the plate 200 to be cleaned.

[0053] The spray head can spray cleaning fluid into the cavity 11 from two directions, ensuring that both sides of the board 200 to be cleaned are thoroughly cleaned. Especially for panel boards or circuit boards with components or solder joints on both sides, it can remove flux residue and other impurities, and thoroughly clean the circuit board.

[0054] The design of the openings 12 at both ends of the housing 10 allows the cleaning fluid to circulate throughout the entire cavity 11, reducing dead zones and further promoting natural flow and drainage of the liquid. Simultaneous spraying of the cleaning fluid from both ends ensures even water pressure on the plate 200 to be cleaned, preventing deformation of the plate 200 or damage to components due to high pressure on one side, thus improving cleaning safety. Furthermore, the openings 12 at both ends of the housing 10 allow the cleaning fluid to contact the plate 200 at different angles, especially in areas below components or near the edges, ensuring that all minute impurities are removed.

[0055] In another embodiment of this application, please refer to Figure 1 and Figure 5 The inclined groove 13 extends from one end face of the housing 10 in the height direction toward the opposite end. The inclined groove 13 forms a slot 131 on the end face of the housing 10. The cleaning fixture 100 also includes a frame 20 adapted to be installed at one end of the housing 10. The frame 20 closes the slot 131 of the inclined groove 13.

[0056] The inclined groove 13 is formed on the inner wall of the housing 10 by extending from one end of the housing 10 along its height direction to the other end face, such as... Figure 1 and Figure 2 The inclined groove 13 is open at one end of the housing 10, and the other end extends into the housing 10 but does not extend beyond the other end of the housing 10. The plate to be cleaned 200 can be directly inserted into the inclined groove 13 through the slot 131 of the inclined groove 13.

[0057] A frame 20 is installed above the housing 10 along its height. The frame 20 is shaped to fit the housing 10, and a connecting opening 21 is provided in the middle of the frame 20, communicating with the opening 12. The frame 20 closes the slot 131 of the inclined groove 13, thus confining the plate to be cleaned 200 within the inclined groove 13. The frame 20 can be installed on the housing 10 by threaded connection or snap-fit ​​connection, etc. In use, the operator only needs to insert the plate to be cleaned 200 into the inclined groove 13 and then cover it with the frame 20 to complete the fixation. No complicated adjustment steps are required, making installation and disassembly simpler and faster.

[0058] The frame 20, through the slot 131 of the closed inclined groove 13, provides constraint to the plate to be cleaned 200, ensuring that it maintains a fixed tilt angle and position during the cleaning process. This prevents the plate to be cleaned 200 from shifting or even falling off due to water flow impact or mechanical vibration, thus contributing to a consistent cleaning effect. When multiple plates to be cleaned 200 are installed, the frame 20 can apply pressure evenly, ensuring that each plate to be cleaned 200 is subject to the same constraint conditions throughout the cleaning process.

[0059] The design of the connecting port 21 on the frame 20 allows the cleaning fluid to enter the cavity 11 through the connecting port 21 and the opening 12, without obstructing the normal flow of the liquid due to the presence of the frame 20. This ensures that the cleaning fluid can cover all critical areas of the board 200 to be cleaned, including the bottom of the flip chip and the soldering positions. In addition, the frame 20 also enhances the structural strength of the entire cleaning fixture 100, reducing the risk of deformation caused by external impacts or internal pressure changes, and extending the service life of the equipment.

[0060] In another embodiment of this application, see [reference] Figure 3 The cleaning fixture 100 also includes a locking member 30 for locking the frame 20 onto the housing 10, the locking member 30 being mounted on the housing 10.

[0061] The frame 20 is connected to the housing 10 via a locking member 30. In one embodiment, the locking member 30 is located on the surface of the housing 10 facing the frame 20, so that the locking member 30 can lock and release the frame 20. This method is convenient for both operation and unlocking.

[0062] The locking element 30 can be a snap-fit, a screw, or an adhesive layer. The locking element 30 can lock the frame 20, ensuring that the frame 20 firmly seals the slot 131 of the inclined groove 13, and also ensuring that it will not loosen accidentally during the cleaning process.

[0063] The locking component 30 reduces friction and wear by locking, extends the service life of the equipment, has a simpler and clearer design, reduces the number of parts and assembly complexity, and lowers manufacturing costs and maintenance difficulty.

[0064] In addition, multiple first threaded holes 14 are provided on the surface of the housing 10 facing the frame 20, and second threaded holes 23 are provided on the surface of the frame 20 facing the housing 10. The first threaded holes 14 and the second threaded holes 23 are connected by screws to fix the frame 20 and the housing 10. That is, the housing 10 and the frame 20 can be further fixed by threaded connection, making the connection between the frame 20 and the housing 10 more stable, ensuring that the plate to be cleaned 200 will not shift when subjected to water flow impact, and ensuring the cleaning quality.

[0065] In another embodiment of this application, please refer to Figure 3 The locking component 30 includes a rotating rod 31 rotatably mounted on the housing 10. The rotating rod 31 is provided with a pressure block 32 adapted to press against the frame 20. The frame 20 is provided with a clearance opening 22 corresponding to the position of the rotating rod 31.

[0066] The pressure block 32 is fixedly connected to the outer wall of the rotating rod 31, which is rotatably connected to the housing 10. By using the rotating rod 31 and the pressure block 32, the operator can easily lock or release the frame 20 without the need for additional tools, greatly simplifying the installation and disassembly process of the plate to be cleaned 200. The pressure block 32 locks the frame 20, ensuring that it securely seals the slot 131 of the inclined groove 13 and prevents accidental loosening during cleaning. When unlocking is required, rotating the pressure block 32 allows it to be removed from the frame 20 and positioned within the clearance opening 22 for easy unlocking.

[0067] In some embodiments, two rotating rods 31 and two pressure blocks 32 are provided and are arranged on the same side of the housing 10, symmetrically arranged along the centerline of that side of the housing 10. This helps to prevent the plate to be cleaned 200 from warping or shifting due to uneven force during the cleaning process, and ensures the stability of the entire cleaning process.

[0068] The two pairs of symmetrically arranged rotating rods 31 and pressure blocks 32 can better disperse the stress acting on the frame 20 and the housing 10, reduce the risk of structural deformation or damage caused by local stress concentration, extend the service life of the equipment, and ensure that each circuit board can be properly fixed, avoiding damage to the circuit board due to excessive pressure or insecure fixing due to insufficient pressure, and reducing the occurrence of skew or twisting.

[0069] In another embodiment of this application, please refer to Figure 2 The groove 131 of the inclined groove 13 is flared.

[0070] The flared design makes the entrance of the inclined groove 13 larger, making it easier for the plate to be cleaned 200 to find the correct entry point during insertion and slide smoothly along the direction of the inclined groove 13, reducing alignment difficulties and improving work efficiency. At the same time, the flared design provides more tolerance space, reducing the possibility of friction or collision between the edge of the plate to be cleaned 200 and the inclined groove 13 during insertion, and reducing the risk of damage to the edge of the plate to be cleaned 200.

[0071] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
