Description

Technical Field

[0001] This invention relates to the field of glass cleaning technology, specifically to a highly adaptable adjustable car curved glass cleaning machine. Background Technology

[0002] Automotive glass is an essential component of a car body, primarily serving a protective function. With the booming development of the new energy vehicle industry, the product range of automotive glass has expanded dramatically, with tens of thousands of glass models used in vehicles. Due to the requirements of the production process, automotive glass needs to be cleaned before processes such as lamination and screen printing. Due to its special strength and structure, cleaning automotive glass requires specialized equipment.

[0003] Currently, the industry commonly uses customized cleaning machines to address these needs. This means that during the design phase, the width of the conveyor channel, support height, spray / brush positioning, and air knife opening are all tied to a fixed size and curvature. This results in the machine only being able to reliably clean a few types of glass that meet specific size and curvature ranges, making it unsuitable for all models. This existing "fixed size / fixed curvature" customization solution still has shortcomings when facing the multi-model, rapidly iterating production model of new energy vehicles. (1) Existing glass cleaning equipment has poor compatibility and high replacement cost. Since there are tens of thousands of glass models used in automobiles, and one machine can only clean a few fixed models, the machine needs to be adjusted or parts need to be replaced when switching models, resulting in high replacement cost and time and effort consumption.

[0004] (2) Existing glass cleaning equipment has the problem of incompatibility of size, curvature and thickness, which leads to cleaning instability. Due to the large variety of glass models, large size range and many curved and irregular shapes of new energy vehicle glass, traditional cleaning machines usually have fixed size and fixed curvature, which makes small glass easy to deviate during cleaning, large glass cannot be "scraped", and curved surfaces cannot be cleaned, reducing the cleaning effect. Lamination and screen printing have extremely high requirements for cleanliness. Uneven cleaning will cause burrs or ink loss in screen printing, and lamination will produce bubbles and delamination, directly threatening the product qualification rate of lamination and screen printing.

[0005] (3) Existing glass cleaning equipment uses "multiple customized machines to cover specifications" in exchange for specification coverage. This not only doubles the equipment purchase and floor space, but also makes the water / air / electrical systems redundant and daily maintenance more complicated. In essence, it still does not have the flexible production capability of one-click model change, which is contrary to the small batch and multi-variety production cycle of new energy and has poor practicality.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0009] Furthermore, the outer width adjustment structure includes a precision lead screw that is rotatably inserted between the two sides of the inner wall of the frame. The precision lead screw is a bidirectional lead screw. One end of the precision lead screw extends outside the box frame and is fixedly connected to a servo motor.

A guide rail is provided on the frame along its width direction. The slider is slidably connected to the guide rail.

[0010] Furthermore, the intermediate height adjustment structure includes a servo motor 2 fixedly mounted at the bottom center of the frame, a precision lead screw 2 fixedly connected to the output end of the servo motor 2, a guide shaft 1 at both ends of the precision lead screw 2, the guide shaft 1 fixedly connected to the bottom of the frame, a lifting seat fixedly connected to the bottom of the two intermediate belt supports, a nut 2 fixedly connected to the bottom of the lifting seat, the nut 2 threadedly connected to the precision lead screw 2, and the lifting seat slidably connected to the guide shaft 1.

[0011] Furthermore, the upper spray pipe is located above the middle belt, and the lower spray pipe is located below the middle belt. Both the upper and lower spray pipes extend along the width direction of the frame.

[0012] Furthermore, the lifting transmission assembly includes a servo motor three fixedly connected to the top of the frame, a precision lead screw three fixedly connected to the top output end of the servo motor three, a nut three threadedly connected to the precision lead screw three, a movable plate fixedly connected to the top of the nut three, guide shaft two fixedly connected to both ends of the bottom of the movable plate, a sleeve fixedly connected to both ends of the top of the frame, the guide shaft two being inserted into the sleeve, and the bottom end of the guide shaft two being fixedly connected to the top of the upper spray pipe.

[0013] Furthermore, the lifting transmission assembly 2 includes a servo motor 4 fixedly connected to the bottom of the frame, a precision lead screw 4 fixedly connected to the top output end of the servo motor 4, a nut 4 threadedly connected to the precision lead screw 4, the top of the nut 4 fixedly connected to the bottom of the lower spray pipe, guide shafts 3 symmetrically provided at both ends of the precision lead screw 4, and collars fixedly connected to the bottom of both ends of the outer side of the lower spray pipe, with the guide shafts 3 inserted into the collars.

[0014] Furthermore, a traction member is wound on the winding device, and the outer end of the traction member is fixedly connected to the second slider.

There is no need to replace parts, no need to manually adjust, and no need for tooling fixtures, which significantly improves the utilization rate and reduces the changeover time from hours to minutes. This reduces manual alignment and repeated trial runs, and improves production efficiency. (3) In this invention, the outer belt assembly, the middle belt assembly and the spray assembly are set up so that the curved glass can be stably transported without deviation by opening and closing the outer belt and floating the middle belt. The upper and lower spray pipes can be raised and lowered to adjust the position, so that the fan-shaped spray is closer to the surface of the curved glass, improving the uniformity of cleaning and increasing the cleanliness of cleaning. This reduces the risk of burrs or ink loss in screen printing, bubbles or delamination in glue due to uneven cleaning, and improves the qualification rate of screen printing or glued products. (4) The scheme of arranging multiple customized machines in parallel in this invention has a small number of machines and a small footprint. The adjustment mechanism is mainly based on standardized servo screw sliders. The water / air / electrical circuits are centrally arranged, making operation and maintenance simpler.

[0026] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] like Figures 1 to 9 As shown, this embodiment proposes a highly adaptable adjustable car curved glass washing machine, including a frame 1, on which a washing section and a drying section are arranged sequentially along its own length.

[0029] The frame 1 has an outer belt assembly 2 at both the front and rear ends on one side. The outer belt assembly 2 includes an outer belt bracket 21 and an outer belt 22 is fitted on the outer belt bracket 21 to form a channel width constraint and participate in the conveying.

[0030] A middle belt assembly 3 is provided in the middle of one side of the frame 1. The middle belt assembly 3 includes a middle belt bracket 31 and a middle belt 32 is sleeved on the middle belt bracket 31. The middle belt bracket 31 is located between two outer belt brackets 21 along the width direction of the frame 1 to provide middle / bottom support. The four belts mainly make contact with the glass through the support fulcrum to reduce the risk of scratches and adapt to irregular curved surface workpieces.

[0031] The frame 1 has an outer width adjustment structure 4 on one side. The outer width adjustment structure 4 includes a precision lead screw 41 that is rotatably inserted between the two sides of the inner wall of the frame 1. The precision lead screw 41 is a bidirectional lead screw. One end of the precision lead screw 41 extends outside the box frame 1 and is fixedly connected to a servo motor 42. The bottom of the outer belt bracket 21 is fixedly connected to a slider 44. Nuts 43 are fixedly connected to both ends of the bottom of the slider 44. The nuts 43 are threaded onto the precision lead screw 41. The frame 1 has a guide rail 45 along its width direction. The slider 44 is slidably connected to the guide rail 45 for limiting and guiding the movement of the slider 44.

[0032] Specifically, servo motor 42 drives precision lead screw 41 to rotate. Since precision lead screw 41 is a bidirectional lead screw, the two nuts 43 generate opposite or opposite displacements in the left-hand and right-hand sections respectively. Through slider 44, the two outer belt brackets 21 are driven to open and close synchronously along guide rail 45, completing the channel width matching and naturally forming automatic centering. After reaching the position, the width is maintained by lead screw self-locking or system locking.

[0033] A middle height adjustment structure 5 is provided on one side of the frame 1. The middle height adjustment structure 5 includes a servo motor 51 fixedly installed at the bottom center of the frame 1. A precision lead screw 52 is fixedly connected to the output end of the servo motor 51. Guide shafts 53 are provided at both ends of the precision lead screw 52. The guide shafts 53 are fixedly connected to the bottom of the frame 1. Lifting seats 54 are fixedly connected to the bottom of the two intermediate belt brackets 31. Nuts 55 are fixedly connected to the bottom of the lifting seats 54. Nuts 55 are threaded to the precision lead screw 52. The lifting seats 54 are slidably connected to the guide shafts 53 for limiting and guiding the movement of the lifting seats 54.

[0034] Specifically, servo motor 251 drives precision lead screw 252 to rotate, which in turn causes nut 255 to drive lifting seat 54 to move vertically up and down along guide shaft 153, thereby raising or lowering the two intermediate belt supports 31 as a whole, so that the support surface of the intermediate belt 32 can adaptively float and match the glass arc height, deep bend and warp.

[0035] A spray assembly 6 is provided on one side of the frame 1. The spray assembly 6 is located in the cleaning section. The spray structure 6 includes an upper spray pipe 61 and a lower spray pipe 62. The upper spray pipe 61 is located above the intermediate belt 32, and the lower spray pipe 62 is located below the intermediate belt 32. Both the upper spray pipe 61 and the lower spray pipe 62 extend along the width direction of the frame 1. The cleaning section is organized according to the water path as a closed loop of flushing, cleaning, and final pure water rinsing, and is used in conjunction with multi-stage filtration and circulation. For the cleaning area involving water or water vapor, the motor, coupling, bearing housing, and electrical installation position are isolated and protected with waterproof and water-proof material layers.

[0036] The top of the upper spray pipe 61 is equipped with a lifting transmission assembly 63. The lifting transmission assembly 63 includes a servo motor 631 fixedly connected to the top of the frame 1. A precision lead screw 632 is fixedly connected to the top output end of the servo motor 631. A nut 633 is threaded onto the precision lead screw 632. A movable plate is fixedly connected to the top of the nut 633. Guide shafts 634 are fixedly connected to both ends of the bottom of the movable plate. Sleeves are fixedly connected to both ends of the top of the frame 1. The guide shafts 634 are inserted into the sleeves and are used to limit and guide the movement of the movable plate. The bottom end of the guide shafts 634 is fixedly connected to the top of the upper spray pipe 61 and is used to drive the middle part of the upper spray pipe 61 to rise and fall to produce bending and change the curvature.

[0037] Specifically, servo motor 3631 drives precision lead screw 3632 to rotate, which in turn causes nut 3633 to drive movable plate to move vertically up and down along guide shaft 2634, thereby driving upper spray pipe 61 to be height positioned, so that upper spray pipe 61 can be driven in the middle to present a position closer to the curvature of the upper surface of curved glass, which is called "adjustable curvature", so that high pressure fan-shaped nozzles are closer to / closer to vertical incident on the glass surface, stripping dust and mold powder.

[0038] The bottom of the lower spray pipe 62 is provided with a lifting transmission assembly 2 64. The lifting transmission assembly 2 64 includes a servo motor 4 641 fixedly connected to the bottom of the frame 1. A precision lead screw 4 642 is fixedly connected to the top output end of the servo motor 4 641. A nut 4 643 is threaded onto the precision lead screw 4 642. The top of the nut 4 643 is fixedly connected to the bottom of the lower spray pipe 62. Guide shafts 3 644 are symmetrically provided at both ends of the precision lead screw 4 642. A collar is fixedly connected to the bottom of both ends of the lower spray pipe 62. The guide shafts 3 644 are inserted into the collars and are used to limit and guide the movement of the lower spray pipe 62.

[0039] Specifically, servo motor 4641 drives precision lead screw 4642 to rotate, which in turn causes nut 4643 to drive collar to move vertically up and down along guide shaft 3644, thereby driving the lower spray pipe 62 to be height positioned, so that the lower spray pipe 62 can be driven in the middle to present a position closer to the curvature of the lower surface of the curved glass, which is called "adjustable curvature", so that the high-pressure fan-shaped nozzle is closer to / closer to vertically incident on the glass surface, stripping away dust and mold powder.

[0040] Furthermore, the two ends of the lower spray pipe 62 are hinged with connecting rods, one end of which is hinged to the slider 44, which makes the curvature of the two ends of the lower spray pipe 62 closer to the curvature of the lower surface of the curved glass.

[0041] On the other side of the frame 1, there is a drying assembly 7. The drying assembly 7 is located in the drying section. The drying assembly 7 includes guide rails 71 symmetrically arranged at both ends of the inner side of the frame 1. Multiple sliders 72 are slidably connected on the guide rails 71. Air knives 73 are fixedly installed on the sliders 72. A winder 74 is fixedly installed at one end of the guide rails 71. A traction component is wound on the winder 74. The outer end of the traction component is fixedly connected to the sliders 72.

[0042] Specifically, the air knife 73 is installed on the guide rail 71 via the slider 2 72. The winding device 74 takes up and releases the traction component to change the position of the slider 2 72 along the guide rail 2 71, thereby changing the extension opening and relative posture of the air knife 73 to adapt to glass outlines of different widths and curvatures. The air from the air knife passes through a uniform air curtain and then through a hot air constant temperature drying zone to remove the residual water film.

[0043] Furthermore, the frame 1 is also equipped with an electronic control system, which is connected to the signals of each servo motor and is equipped with a recipe storage module. It stores multiple sets of parameter records for the width, height, spray pipe position and air knife position corresponding to different sizes and curvatures of glass. By inputting the size through the touch screen or calling the recipe, the servo motors are driven to automatically complete the width adjustment, height adjustment and centering.

[0044] In practical implementation, the operator first inputs the size and curvature model of the curved glass to be cleaned on the human-machine interface, or directly calls the stored recipe. The recipe must at least record the channel width value, the middle belt support height value, the lifting position of the upper / lower spray pipe, and the opening and closing position of the air knife corresponding to this model.

[0045] Next, the system drives the servo motor 42 to rotate the precision lead screw 41 according to the formula value. The two nuts 43 move along the left and right rotation sections respectively, and are guided by the slider 44 along the guide rail 45. This drives the two outer belt brackets 21 to open and close synchronously to the target width. The conveying channel formed by the two outer belts 22 matches the width of the glass and achieves automatic centering. At the same time, the servo motor 51 drives the precision lead screw 52 to rotate, and the nut 55 drives the lifting seat 54 to rise and fall along the guide shaft 53. The two middle belt brackets 31 and the middle belt 32 move up or down to the support height that is adapted to the current glass arc height, so that the upper sections of the four belts together form a conveying surface that fits the bottom of the curved glass.

[0046] Afterwards, the glass enters the frame 1 from the upstream section and is supported by four belts and conveyed along the length of the frame: it first enters the cleaning section. In the cleaning section, the upper spray pipe 61 and the lower spray pipe 62 are adjusted to the positions given by the formula by the lifting transmission assembly 63 and the lifting transmission assembly 64, respectively, so that the arc-shaped spray pipe and its fan-shaped nozzle are kept within the working distance set by the formula from the upper and lower surfaces of the glass. High-pressure water is sprayed from the nozzles to remove dust and mold powder. The final stage is connected to pure water rinsing to reduce residue. The couplings, bearing housing outer rings and electrical installation positions used in the water-contact area of ​​the cleaning section are covered with waterproof and water-proof isolation layers.

[0047] After leaving the cleaning section, the glass enters the drying section. The rewinder 74 rewinds or unwinds the traction component, causing the slider 72 to slide along the guide rail 71, so that each air knife 73 reaches the opening and closing position and height posture given by the formula. The air knife outputs high-pressure airflow / hot air to peel off and dry the water film on the glass surface. The entire process does not require the replacement of parts or tooling fixtures, realizing fully automatic, high-precision, and rapid adaptation of the transmission channel to automotive glass with different length, width, and curvature heights. No parts need to be replaced, no manual adjustment is required, and no tooling fixtures are required. Moreover, the switching between different models can be completed by one-click formula call, which can be compatible with flat, single-curved, double-curved, and deeply curved glass, meeting the universal cleaning needs of tens of thousands of car models.
