Description

Technical Field

[0001] This utility model relates to the field of electronic device manufacturing technology, specifically to a cleanroom plate double-track adhesive removal device and a cleanroom plate double-track composite device. Background Technology

[0002] With the increasing use of cleanroom panels, the demand for production efficiency is constantly rising. The original pressing of cleanroom panels using a static press meant the panels were stationary during lamination, slowing down the entire production line. Switching to a dual-track machine for panel lamination significantly increases production speed. However, during lamination, a small amount of adhesive overflows from the panels and accumulates on the track plates of the dual-track machine. Over time, this solidifies and affects the flatness of the track plates, consequently impacting the flatness of the cleanroom panel surface. In actual production, manual scraping of the adhesive is required from the exit points of the dual-track machine, which is time-consuming and labor-intensive. Furthermore, scraping the adhesive during production is not feasible, and the machine is running, posing a safety hazard. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This embodiment provides a dual-track adhesive removal device for a cleanroom plate, see reference. Figures 1-4 The cleanroom plate dual-track adhesive removal device shown includes a scraper 44, an adjusting device, a fixing device, a connecting device, and a driving device. The adjusting device is used to adjust the position and angle of the scraper 44, which is located at one end of the adjusting device. The fixing device is used to fix the adhesive removal device to the cleanroom plate dual-track. The connecting device connects the fixing device and the adjusting device. The driving device, connected to the fixing device, provides a power source to the scraper 44 to drive it for adhesive removal. The cleanroom plate dual-track adhesive removal device provided in this embodiment can be installed in the narrow space at the bottom of the dual-track machine outlet. It can automatically remove adhesive during production, removing it before it is completely cured. Residual adhesive will automatically fall to the ground and accumulate to a certain level for manual cleaning. The width of the cleanroom plate can be adjusted as needed, and the device can adjust the width accordingly.

[0033] In one embodiment of this utility model, reference is made to Figure 1 As shown, the fixing device includes a base plate 1, a mounting plate 2, a frame 3, and a pressure rail 4. The base plate 1 is welded to the double tracks of the cleanroom plate via the mounting plate 2; the frame 3 supports the entire adhesive removal device; and the pressure rail 4 fixes the frame 3 to the base plate 1.

[0034] In one embodiment of this utility model, reference is made to Figure 5 As shown, a height adjustment seat 5 is installed at the bottom of the base plate 1. The height adjustment seat 5 is equipped with height adjustment screws. By rotating these screws, the entire adhesive removal device is kept parallel to the chain plates of the double-track cleanroom machine. The scraper 44 contacts the chain plates of the double-track machine parallel to each other, improving the adhesive removal effect. When adhesive removal is not required during cleanroom plate production, the entire device can be lowered by rotating the height adjustment screws, causing the scraper 44 to disengage from the chain plates, thereby extending the service life of the scraper 44. The base plate 1 also has through holes and threaded holes, allowing it to be fixed to the double-track machine frame 3 using threaded fasteners when welding is inconvenient.

[0035] In one embodiment of this utility model, reference is made to Figure 2 As shown, the cleanroom plate dual-track adhesive removal device may include two oppositely arranged fixing devices and two oppositely arranged scraper discs 44, respectively disposed at both ends in the width direction of the dual tracks. The drive device is mounted on one of the fixing devices. The cleanroom plate dual-track adhesive removal device also includes a transfer device connecting the two scraper discs 44, wherein one end of the transfer device is connected to the drive device.

[0036] In one embodiment of this utility model, reference is made to Figure 1 , Figure 2 and Figure 3 As shown, the transmission device also includes a synchronous pulley 8, a double-row synchronous pulley 10, a short synchronous belt 11, a long synchronous belt 12, a fixed-side pulley seat 14, a tensioning-side pulley seat 15, a pulley adjusting seat 16, an idler shaft 45, and an idler pulley 17. The long synchronous belt 12 passes over the idler pulley 17, the synchronous pulleys, the long pin shaft 48, and the short pin shaft 49, enabling one motor to drive two degumming heads. Specifically, to enable one motor to drive two degumming heads and to adjust the relative distance to accommodate different plate widths, a structure with fixed pulleys at both ends and a movable pulley in the middle is adopted. When the middle pulley moves, the length of the long synchronous belt 12 only changes slightly. To keep the long synchronous belt 12 always taut, a synchronous belt tensioner 28 is installed in the middle of the device. This synchronous belt tensioner 28 can rotate around its mounting fulcrum. When the length of the long synchronous belt 12 changes slightly, the rollers on the tensioner firmly hold the long synchronous belt 12 against the rubber spring, keeping it taut. To increase the wrap angle of the central movable pulley, there is an idler pulley 17 and an idler pulley shaft 45 on each side, thereby preventing the pulley from slipping during degumming.

[0037] In one embodiment of this utility model, reference is made to Figure 2 and Figure 3 As shown, the drive device includes a motor mount 7 and a motor adjustment seat 13. The motor mount 7 is fixed to the frame 3, and a motor is mounted on the motor mount 7; preferably, the motor is a DC geared motor 9. The motor mount 7 is mounted on the motor mount 7 adjustment seat; the motor mount 7 has elongated slots for easy installation, and the motor adjustment seat 13 is equipped with adjusting screws and nuts to adjust the position of the motor mount 7, thereby ensuring that the short belt in the transmission device remains taut. A cover 47 is provided on the motor to prevent safety hazards during use.

[0038] In one embodiment of this utility model, reference is made to Figure 1 and Figure 4 As shown, the dual-track adhesive removal device for the purification plate uses multiple synchronous pulleys 8 as power transmission components. One of them is fixed to a DC geared motor 9, serving as the power output source. The fixed pulley on the motor side is a double-row synchronous pulley 10, which is fixed to the fixed-side pulley seat 14 on the motor side via a long pin shaft 48 and a deep groove ball bearing 40, thereby transmitting power from the DC geared motor 9 to the middle movable pulley. The fixed pulley away from the motor side is a synchronous pulley 8, which is mounted on the tensioning-side pulley seat 15 on the right side via a short pin shaft 49 and a deep groove ball bearing 40. The tensioning-side pulley seat 15 has a long slot, and the pulley adjusting seat 16 is equipped with two adjusting screws and nuts to adjust the position of the tensioning-side pulley seat 15, facilitating the installation and replacement of the long synchronous belt 12.

[0039] In one embodiment of this utility model, reference is made to Figure 1 As shown, multiple timing belt support blocks 29 are installed on the loose side of the long timing belt 12. Angle seats 46 are installed on the timing belt support blocks 29. The angle seats 46 have long slots to facilitate the adjustment of the timing belt support height.

[0040] In one embodiment of this utility model, reference is made to Figure 7 As shown, the connecting device includes a lateral adjusting screw 20; the guide shaft clamping seat 19 clamps two guide shafts 18 at both ends and is fixed on the double-track frame 3, serving as the guide part of the entire device. Since the width adjustment is not frequent, the lateral adjusting screw 20 can use flanged oilless bearings 21 and shaft end flanged oilless bearings 26 as rotational supports for the fixed and support ends, making the entire device more compact and reducing costs.

[0041] In one embodiment of this utility model, reference is made to Figure 7 The connecting device shown also includes a shaft end nut seat 27 disposed in the middle of the connecting device; the connecting device also includes a screw nut 24 for adjusting the lateral adjusting screw 20; the connecting device also includes a screw clamping seat 30.

[0042] In one embodiment of this utility model, reference is made to Figure 3 and Figure 7 As shown, the dual-track adhesive removal device for the purification plate also includes an adjusting handwheel 23, which is connected to the lateral adjusting screw 20. The adjusting handwheel 23 facilitates the rotation of the lateral adjusting screw 20. When the scraper disc 44 is severely worn and needs replacement, rotating the adjusting handwheel 23 moves the left and right scraper discs 44 to the outside of the chain plate. Replacement requires no additional tools; simply pull out the scraper disc 44 and replace it with a new one.

[0043] In one embodiment of this utility model, reference is made to Figure 7 As shown, the limit screw 22 is fixed to the inside of the guide shaft clamping seat 19 to limit the adjustment of the movable pulley in the middle from going out of range.

[0044] In one embodiment of this utility model, reference is made to Figures 4-6 As shown, the adjustment device includes: a frame structure formed by fixing multiple vertical plates 31 and flat plates 32; a horizontal shaft 34 and a vertical shaft, which are disposed inside the frame structure; two helical gears 35, one of which is disposed on the horizontal shaft 34 together with the transmission device, and the other helical gear 35 and a turntable 39 are disposed on the vertical shaft; and multiple angular contact bearings 36, which are respectively disposed at both ends of the horizontal shaft 34 and the vertical shaft.

[0045] To reduce the overall working height of the device, the movable pulley section in the middle is fixed to the side of the nut seat 25 via the upright plate 31. The left and right upright plates 31 and the upper and lower flat plates 32 are fixed together with threaded fasteners to form a sturdy frame structure. Since the belt rotation and the required rotation for degreasing are inconsistent, a pair of helical gears 35 are added in the middle of the frame for transition. One helical gear 35 is mounted on the horizontal shaft 34 together with the synchronous pulley 8, and the other helical gear 35 is mounted on the vertical shaft 33 together with the turntable 39. The two are staggered shafts, and the power is rotated by the helical gear 35. Since the helix angle of the helical gear 35 reaches 45°, the axial force is relatively large. A pair of angular contact bearings 36 are installed at both ends of the vertical shaft 33 and the horizontal shaft 34 to bear both radial and axial forces. The bearing clearance is adjusted using round nuts and locking washers. After the rotation is achieved by the helical gear 35, the rotation of the turntables 39 at both ends becomes symmetrical. During degreasing, the double track chain plates of the scraper disc 44 can move relatively to form the optimal rotation direction, improving the degreasing efficiency. Considering the need for gear installation clearance adjustment, the left and right vertical plates 31 and the upper and lower flat plates 32 can be slightly adjusted through the gaps in the threaded through holes. Through the helical gear reversing mechanism, the rotation direction of the long synchronous belt 12 remains parallel to the double track chain plates, preventing the synchronous belt from vertically driving, thus improving the stability and service life of the synchronous belt drive.

[0046] In one embodiment of this utility model, reference is made to Figure 9 As shown, the adjusting device includes a central gear 37 and a planetary gear 38. The central gear 37 is fixed to the plate 32; the planetary gear 38 is connected to the turntable 39 via a deep groove ball bearing 40 and a planetary gear shaft 41.

[0047] During glue removal, the simple rotation of the scraper 44 is inefficient when facing the moving chain plate; a swing function is needed simultaneously. Therefore, a central gear 37 is fixed to the plate 32, and planetary gears 38 on both sides of the central gear 37 are connected to the turntable 39 via deep groove ball bearings 40 and planetary gear shafts 41. Preferably, the gear ratio between the central gear 37 and the planetary gears 38 is 2:1. When the vertical shaft 33 rotates, it drives the scraper 44 to rotate at twice its own speed while simultaneously revolving around the vertical shaft 33, creating a swing function and thus improving glue removal efficiency. A pair of deep groove ball bearings 40 are installed at the bottom of the vertical shaft 33, reducing the cantilever length and thus better bearing the forces exerted on the turntable 39 during glue removal.

[0048] In one embodiment of this utility model, since the traditional flat key structure is limited by its short length and cannot transmit a large torque, in order to reduce the overall working height of the device, the turntable 39 is chosen as a flat disc structure (see reference). Figure 9As shown, the flat disc structure further reduces rotational inertia. The torque between the vertical shaft 33 and the turntable 39 is transmitted through two cylindrical pins 50, resulting in less weakening of the shaft and a more compact overall structure.

[0049] In one embodiment of this utility model, because the entire device does not maintain perfect parallelism with the chain plates of the dual-track machine, the scraper 44 cannot be completely pressed against the chain plates, resulting in excessive localized wear and reduced service life. (Reference) Figure 8 As shown, in this embodiment, convex and concave spherical surfaces are machined at the bottom of the planetary gear shaft 41 and the top of the scraper 44, respectively. The interaction of the convex and concave spherical surfaces allows the scraper 44 to make relatively small oscillations, thus enabling the scraper 44 to better fit the chain plate and increase the adhesive removal working area. A flat key 43 is directly mounted on the end face of the scraper 44 and the deep groove ball bearing 40 for power transmission, realizing the power transmission between the planetary gear shaft 41 and the scraper 44 without increasing the thickness of the scraper 44. A retaining ring 42 is installed between the flat key 43 and the scraper 44 as a safety component to prevent the scraper 44 from detaching from the planetary gear shaft 41 in extreme cases.

[0050] In one embodiment of this utility model, to avoid damaging the surface of the chain plate during glue removal, the scraper 44 can be made of a wear-resistant and high-temperature-resistant non-metallic material. (Reference) Figure 10 As shown, the bottom surface of the scraper 44 is machined with multiple grooves, and the raised parts can serve as cutting edges for removing adhesive. Multiple slots are machined around the grooves as expansion joints to prevent the bottom surface of the scraper 44 from becoming uneven after being deformed by heat at high temperatures.

[0051] In one embodiment of this invention, the higher the rotational speed of the scraper 44, the higher the glue removal efficiency, but the faster the wear and the shorter the service life. Two adjacent scraper 44s can be installed at the turntable 39 in the glue removal device. With the output speed of the DC geared motor 9 remaining constant, the glue removal efficiency is doubled, while the service life of the scraper 44 is also guaranteed. Considering extreme usage scenarios, two additional scraper 44s can be configured in the turntable 39 to further improve the glue removal efficiency. It is understood that the number of scraper 44s can be set according to actual production needs; this invention does not limit the number of scraper 44s.

[0052] In one embodiment of this utility model, reference is made to Figure 1As shown, the dual-track adhesive removal device for the purification plate may further include a bamboo-joint spray nozzle 51, connected to the adjustment device; the bamboo-joint spray nozzle 51 moves with the scraper and is used to spray adhesive remover. Preferably, the bamboo-joint spray nozzle 51 is a flexible adjustable bamboo-joint spray nozzle, which can automatically move with the scraper and spray release agent and adhesive remover at the glue overflow position of the chain plate, reducing the adhesion between the glue and the chain plate, making it easier for the scraper to remove the glue, while reducing the friction between the scraper and the chain plate and improving the life of the scraper.

[0053] In one embodiment of this utility model, reference is made to Figure 11 As shown, the connecting device also includes a guiding and width adjustment mechanism. The guiding and width adjustment mechanism is installed side by side with the adjustment device, which reduces the working height of the entire device and makes it easy to install in the narrow space under the double tracks. It can adapt to existing double tracks without the need for additional modifications to existing equipment, thus reducing the customer's operating costs.

[0054] In one embodiment of this utility model, the rotation directions of the scraper discs 44 on the left and right sides are mirror symmetrical, which makes it easier to throw the removed residual glue from the inside out, thus improving the glue removal efficiency.

[0055] In one embodiment of this invention, the scraper disc 44 can rotate planetarily around the common vertical axis 33, enabling it to perform both rotational and oscillating adhesive removal. Compared to a purely rotary adhesive removal method, this significantly improves adhesive removal capacity at the same rotational speed. The relative positions of the scraper discs are adjustable. Using a single DC geared motor 9 to achieve these functions improves the equipment's integration, simplifies control, facilitates speed adjustment, and reduces costs.

[0056] This embodiment provides a cleanroom plate dual-track composite device, see reference. Figures 12-15 As shown, the cleanroom plate dual-track composite device includes: the cleanroom plate dual-track adhesive removal device mentioned above; dual-track machine chain plate; dual-track machine frame, wherein the dual-track machine chain plate is installed on the dual-track machine frame, and the cleanroom plate dual-track adhesive removal device is fixed on the dual-track machine frame.

[0057] In one embodiment of this utility model, the scraper of the cleaning plate double track adhesive removal device is arranged parallel to the chain plate of the double track machine.

[0058] In one embodiment of this utility model, since the curing of adhesive is affected by time and temperature, the operating temperature of the dual-track machine is generally high during production to ensure that the adhesive in the cleanroom board cures as quickly as possible. To achieve automated adhesive removal, it is necessary to minimize the curing time of the adhesive. Since the cleanroom board has just undergone hot-pressing lamination, the overflowing adhesive has not yet completely cured. Installing the adhesive removal device on the lower side of the dual-track machine outlet does not affect the production of the board and can immediately remove the adhesive before it completely cures.
