Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of end-sealing machine equipment, in particular to a method and device for slurry spreading on an end-sealing plate and for slurry line drawing and thickness parallel detection. Background Art
[0002] Traditional chip component end-capping slurry-spreading equipment simply spreads the slurry and performs end-capping. This method first uses a scraper to flatten the slurry on the slurry pan. A lead screw then moves the slurry pan forward and backward beneath the scraper, while the scraper remains stationary. Because the gap between the scraper and the slurry pan is kept very small, this relative movement ensures a uniform slurry thickness across the slurry pan surface.
[0003] In existing production, a common end-capping slurry-spreading method and device first neatly adheres multiple chip electronic components to a board. A large suction cup is then used to hold the back of the board, with all the chip electronic components on the other side neatly protruding at one end. The suction cup is then controlled to neatly immerse the held end of the chip electronic component in the slurry on the slurry tray, coating the ends of the chip components with electronic slurry. However, this method can cause a small amount of electronic components to fall off during the coating process. These fallen components can remain in the slurry tray, or even remain in the gap between the scraper and the slurry tray, resulting in an uneven slurry thickness on the slurry tray. This uneven slurry thickness can affect the production of chip electronic components. Summary of the Invention

Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0036] The method for slurry laying, slurry line drawing and thickness parallel detection of end capping board of the present invention comprises:
[0037] A sensor moving mechanism is set above the slurry disc moving mechanism and perpendicular to the moving direction of the slurry disc, and a slurry thickness detection sensor is installed on the sensor moving mechanism; while the slurry disc moves back and forth, the sensor moves left and right perpendicular to the moving direction of the slurry disc, and the moving sensor moves above the moving slurry disc in the shape of several connected horizontal "V"-shaped tracks, so that the sensor detection range can cover the slurry layer at every position on the slurry disc to detect the slurry thickness at each position; if the slurry thickness is detected to be uneven, an alarm will be issued, and the machine will be stopped in time to detect the cause of the uneven slurry thickness, so as to solve the problem of uneven coating on the ends of electronic components in real time.
[0038] In an embodiment of the present invention, the method further includes:
[0039] An adjusting bolt is provided on the sensor moving mechanism to adjust the parallelism between the entire mechanism and the slurry disc, so as to more accurately measure the thickness change of the slurry on the surface of the slurry disc;

[0041] A limit block is installed on the sensor moving mechanism to limit the left and right moving range of the entire slurry thickness sensor.
[0042] In an embodiment of the method of the present invention, the slurry thickness detection sensor adopts an optical fiber sensor. When in use, the optical fiber sensor first emits a beam of infrared light. When the slurry on the slurry disk encounters the infrared light beam, it will reflect back a part of the light. The reflected light is received by the detector inside the sensor, and the received reflected light is converted into a digital signal by the signal processor for output, so as to understand the change of the slurry thickness in real time and in detail.
[0043] like Figure 1-5 As shown, this embodiment adopts a device for end plate slurry laying and slurry line drawing and thickness parallel detection method, including a frame, a slurry disc 11 installed on the frame, a slurry disc driving mechanism and a scraper mechanism. A sensor moving mechanism is provided on the frame above the slurry disc 11 and perpendicular to the moving direction of the slurry disc 11. The sensor moving mechanism includes: two support columns 12 arranged on both sides of the slurry disc 11 and a mounting cross plate 13 installed on the two support columns 12 and spanning the slurry disc 11. A transverse guide rail 5 is provided on the mounting cross plate 13, and a slide 71 is installed on the transverse guide rail 5. A slurry thickness detection sensor 7 is installed at the lower part of the slide 71. The slurry thickness detection sensor 7 is connected to a controller with an alarm module. The slide 71 is driven by the transverse driving mechanism to carry the slurry thickness detection sensor 7 for transverse reciprocating movement along the transverse guide rail 5.
[0044] The transverse driving mechanism of the preferred embodiment of the present invention includes a servo motor 1, a reducer 2 and two fixed synchronous wheels 3 installed on the mounting transverse plate 13, and a synchronous belt 10 is installed on the two fixed synchronous wheels 3. The connecting line of the two fixed synchronous wheels 3 is parallel to the guide rail 5, and the slide 71 is connected to the synchronous belt 10.
[0045] As another embodiment, the transverse driving mechanism includes a servo motor, a transmission gear and a ball screw installed on the mounting transverse plate 13, and the slide 71 is connected to the ball screw.
[0046] As another embodiment, the transverse driving mechanism includes a cylinder and a piston rod installed on the mounting transverse plate 13, and the slide 71 is connected to the piston rod.
[0047] In a preferred embodiment of the present invention, bolt seats 40 and adjusting bolts 4 vertically screwed on the bolt seats 40 are respectively provided on both sides of the two support columns 12. The bolt seats 40 are installed on the two support columns 12, and the top screw heads of the adjusting bolts 4 are in conflict with the bottom of the mounting cross plate 13; a waist-shaped hole 41 is provided on the mounting cross plate 13, and the two ends are fixed by upper bolts passing through the waist-shaped hole 41 and the threaded holes of the two support columns 12 behind, so that the mounting cross plate 13 is fixed to the two support columns 12.
[0048] The slurry thickness detection sensor 7 is a fiber optic sensor, which includes a light source, an optical fiber, a detector, and a signal processor. The warning module includes a three-color light module or a sound warning module, or a combination of the two. In this embodiment, the warning module is a sound warning module.
[0049] like Figure 1 As shown, a position sensor 6 is mounted on the mounting plate 13 to limit the left and right movement range of the entire slurry thickness sensor 7 at the software level. A limit block 8 is mounted on the mounting plate 13 to limit the left and right movement range of the entire slurry thickness sensor 7 at the hardware level. A limit block 72 is provided on the slide 71 to cooperate with the position sensor 6.
[0050] like Figure 1 As shown, a drag chain 9 is installed on the mounting cross plate 13 to protect the line from being worn during continuous movement. One end of the drag chain 9 is connected to the mounting cross plate 13 , and the other end of the drag chain 9 is connected to the slide 71 .
[0051] The working principle of the device for slurry spreading, slurry line drawing and thickness parallel detection of the end-capping plate of the present invention is as follows:
[0052] like Figure 1 As shown, the device is fixed on the end-sealed pulp disc and moves back and forth with the pulp disc ( Figure 1 、 Figure 4 The direction of movement is marked on the top), and at the same time, the synchronous belt 10 of the detection device drives the slurry thickness detection sensor 7 to move left and right ( Figure 1 、 Figure 4 There is a moving direction on the ). Figure 5 As shown, as they move relative to each other, the slurry thickness detection sensor 7 will eventually move out of several connected horizontal "V"-shaped tracks on the slurry disk 11. The slurry thickness detection sensor 7 moves left and right while detecting the slurry thickness at each position of the slurry disk 11. If it is detected that the thickness of the slurry is uneven, an alarm will be issued with sound or light.
[0053] like Figure 1 As shown, the servo motor 1 drives the reducer 2 to rotate the fixed synchronous wheel 3, and the synchronous wheel 3 drives the synchronous belt 10 and causes the slurry thickness detection sensor 7 fixed on the synchronous belt 10 to move left and right.
[0054] In a preferred embodiment of the present invention, the slurry thickness detection sensor 7 utilizes a fiber optic sensor, which comprises a light source, an optical fiber, a detector, and a signal processor. During operation, the fiber optic sensor first emits an infrared beam. The slurry on the slurry disc 11 reflects a portion of the infrared beam, which is then received by the detector within the slurry thickness detection sensor 7. The signal processor then converts the received reflected light into a digital signal for output, providing real-time and detailed information on changes in slurry thickness.
[0055] like Figure 1-Figure 3 As shown, the slide 71 fixes the entire slurry thickness detection sensor 7 so that it can move left and right with support. While the entire mechanism is installed, the parallelism of the entire mechanism and the slurry disc 11 can be adjusted by adjusting the bolt 4, so as to more accurately measure the thickness change of the slurry on the surface of the slurry disc 11. The top of the adjusting bolt 4 supports the entire mounting cross plate 13 above. By rotating the adjusting bolt 4, the adjusting bolt 4 can be moved up and down against the entire mounting cross plate 13, thereby fine-tuning the parallelism of the entire mounting cross plate 13 and the slurry disc 11, so that the slurry thickness detection sensor 7 can more accurately detect the thickness of the slurry.
[0056] The position sensor 6 is installed to limit the left and right movement range of the entire slurry thickness sensor at the software level, and the limit block 8 is added to limit the left and right movement range of the entire slurry thickness sensor at the hardware level. Since the entire mechanism moves left and right, it is necessary to install a drag chain 9 to protect the circuit from constant movement and wear.
[0057] Figure 1 The structure and connection relationship of the device for slurry spreading, slurry marking and thickness parallel detection of the end plate of the present invention are only briefly shown. However, this figure is only for the purpose of showing the main structure and connection relationship of the present invention. Some other mechanical parts are removed in the figure, such as the scraper drive mechanism and transmission device. Therefore, this embodiment Figure 1 The display is not to be regarded as limiting the present invention to the only structure and connection relationship.
[0058] The innovative focus of the present invention lies in the method, mechanical structure and connection relationship. The equipment system controller controls the actions of the servo motor 1, the slurry disk drive motor, the slurry thickness detection sensor 7, the scraper drive motor, the position sensor 6, etc., and the corresponding electronic control system by writing and setting the program. The details will not be elaborated here.

Any modifications or substitutions that can be readily conceived by a person skilled in the art within the technical scope disclosed herein are intended to be encompassed within the scope of protection of the present invention.
