Description

Technical Field

[0001] The invention relates to the technical field of end-capping machine equipment, and in particular to a method and device for parallel detection of slurry laying, slurry line drawing and thickness on an end-capping plate. Background Art

[0002] Traditional chip component end-sealing slurry spreading equipment only spreads the slurry and performs end-sealing. The method is to first use a scraper to scrape the slurry in the slurry plate flat, and then drive the slurry plate under the scraper forward and backward through the lead screw, while the scraper remains stationary. Since the gap between the scraper and the slurry plate is controlled to be very small, the relative movement of the scraper and the slurry plate ensures that the slurry thickness on the surface of the slurry plate is uniform.

[0003] In existing production, a common end-sealing slurry spreading method and device is to first neatly stick multiple chip electronic components on a board, then use a large suction cup to suck the back of the entire board, and all the chip electronic components on the other side of the board neatly protrude one end, and then control the entire suction cup to make the end of the sucked chip electronic component neatly immersed in the slurry on the slurry tray, so that the end of the chip component is coated with electronic slurry. However, this method may cause a small amount of electronic components to fall off when the chip component end is coated, and the fallen electronic components will remain in the slurry tray, and may even remain in the gap between the scraper and the slurry tray, resulting in uneven slurry thickness on the slurry tray. Once the slurry thickness is uneven, it will affect the production of chip electronic components. Summary of the invention

[0004] In view of the problems and shortcomings of the prior art, the present invention provides a method and device for slurry laying on end capping plates and slurry line drawing and thickness parallel detection, so as to achieve uniform slurry thickness and improve the slurry laying speed and production efficiency of end capping plates.

[0005] The technical solution of the present invention is achieved in this way: The method for testing the slurry laying, slurry marking and thickness of the end capping plate includes: A sensor moving mechanism is arranged 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 forward and backward, the sensor moves left and right perpendicular to the moving direction of the slurry disc. The moving sensor moves out a number of connected horizontal "V"-shaped tracks above the moving slurry disc, 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 uneven slurry thickness is detected, a warning will be issued, and the machine will be stopped in time to detect the cause of the uneven slurry thickness and solve the problem of uneven coating on the ends of electronic components in real time.

[0006] The method for slurry laying and slurry line drawing and thickness parallel detection of end capping board further includes: 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; A position sensor is installed on the sensor moving mechanism to limit the left and right moving range of the entire slurry thickness sensor; A limit block is installed on the sensor moving mechanism to limit the left and right moving range of the entire slurry thickness sensor.

[0007] A method for parallel detection of slurry laying, slurry line drawing and thickness on end capping plates. Furthermore, the slurry thickness detection sensor adopts an optical fiber sensor. When in use, the optical fiber sensor first emits an infrared light beam. The slurry on the slurry disk will reflect back a part of the light after encountering the infrared light beam. The reflected light is received by the detector inside the sensor, and the received reflected light is converted into a digital signal for output through a signal processor, thereby realizing the change of slurry thickness in real time and in detail.

[0008] The present invention adopts the above-mentioned device for slurry spreading on the end plate and the method for parallel detection of slurry line drawing and thickness, comprising a frame, a slurry disc mounted on the frame, a slurry disc driving mechanism and a scraper mechanism, and a sensor moving mechanism is arranged on the frame above the slurry disc and perpendicular to the moving direction of the slurry disc, and the sensor moving mechanism comprises: Two support columns are arranged on both sides of the pulp disk and a mounting cross plate is installed on the two support columns and spans the pulp disk, wherein a transverse guide rail is provided on the mounting cross plate, a slide is installed on the transverse guide rail, a slurry thickness detection sensor is installed at the lower part of the slide, the slurry thickness detection sensor is connected to a controller with a warning module, and the slide is driven by a transverse driving mechanism to carry the slurry thickness detection sensor to move back and forth laterally along the transverse guide rail.

[0009] The traverse drive mechanism can be realized by adopting the following technical solutions: As a technical solution, the transverse driving mechanism includes a servo motor, a reducer and two fixed synchronous wheels installed on the mounting transverse plate. The two fixed synchronous wheels are installed with synchronous belts. The connecting line of the two fixed synchronous wheels is parallel to the guide rail, and the slide is connected to the synchronous belt.

[0010] As a technical solution, the transverse driving mechanism includes a servo motor, a transmission gear and a ball screw mounted on the mounting transverse plate, and the slide is connected to the ball screw.

[0011] As a technical solution, the transverse driving mechanism includes a cylinder and a piston rod installed on the mounting transverse plate, and the slide seat is connected to the piston rod.

[0012] Furthermore, bolt seats and adjusting bolts vertically screwed on the bolt seats are respectively provided on both sides of the two support columns. The bolt seats are installed on the two support columns, and the top screw heads of the adjusting bolts are in conflict with the bottom of the mounting cross plate. The mounting cross plate is provided with waist-shaped holes, and the two ends are fixed by upper bolts passing through the waist-shaped holes and the threaded holes of the two support columns behind, so that the mounting cross plate is fixed on the two support columns. When it is necessary to adjust the parallelism, first loosen the bolts passing through the waist-shaped holes, then adjust the lifting and lowering of the adjusting bolts to the appropriate position, and then tighten the bolts, so as to adjust the parallelism of the mounting cross plate and the paddle disc. The slurry thickness detection sensor adopts an optical fiber 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.

[0013] Furthermore, a position sensor is installed on the installation horizontal plate to limit the left and right movement range of the entire slurry thickness sensor at the software level; A limit block is installed on the installation transverse plate to limit the left and right moving range of the entire slurry thickness sensor at the hardware level, and a limit stopper matched with the position sensor is provided on the slide seat.

[0014] Beneficial effects of the present invention: The present invention sets a sensor moving mechanism above the slurry disk moving mechanism and perpendicular to the moving direction of the slurry disk. The slurry thickness detection sensor is installed on the sensor moving mechanism. As the slurry disk moves forward and backward, the synchronous belt of the detection device drives the slurry thickness detection sensor to move left and right. As the two move forward and backward and left and right relative to each other, the slurry thickness detection sensor finally walks out a horizontal "V"-shaped track like several connected ones on the slurry disk, so that the sensor detection range can cover the slurry layer at every position on the slurry disk, thereby detecting the slurry thickness at each position. If the slurry thickness is detected to be uneven, a warning reminder will be issued, and the cause of the uneven slurry thickness will be detected. For example, the uneven slurry thickness caused by the falling of electronic components can be detected in time, and the problem of uneven coating of the electronic component ends can be solved in real time. The slurry spreading speed of the end plate is improved, and the production efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the 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. On the contrary, these embodiments are provided in order 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.

[0022] The method for slurry laying, slurry line drawing and thickness parallel detection of end capping board of the present invention comprises: A sensor moving mechanism is arranged above the slurry disk moving mechanism and perpendicular to the moving direction of the slurry disk, and a slurry thickness detection sensor is installed on the sensor moving mechanism; while the slurry disk moves forward and backward, the sensor moves left and right perpendicular to the moving direction of the slurry disk, and the moving sensor moves above the moving slurry disk in the shape of several connected horizontal "V"-shaped tracks, so that the sensor detection range can cover the slurry layer at each position on the slurry disk, so as to detect the slurry thickness at each position; if uneven slurry thickness is detected, a warning reminder will be issued, and the machine will be stopped in time to detect the cause of uneven slurry thickness, so as to solve the problem of uneven coating on the ends of electronic components in real time.

[0023] In an embodiment of the present invention, the method further comprises: 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; A position sensor is installed on the sensor moving mechanism to limit the left and right moving range of the entire slurry thickness sensor; A limit block is installed on the sensor moving mechanism to limit the left and right moving range of the entire slurry thickness sensor.

[0024] In the method embodiment of the present invention, the slurry thickness detection sensor adopts an optical fiber sensor. When in use, the optical fiber sensor first emits an infrared light beam. The slurry on the slurry disk will reflect back a part of the light after encountering the infrared light beam. 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, thereby realizing the change of the slurry thickness in real time and in detail.

[0025] like Figure 1-5 As shown, the present embodiment adopts a device for paving slurry on an end plate and a method for drawing lines and detecting thickness of the slurry in parallel, including a frame, a slurry disk 11 installed on the frame, a slurry disk driving mechanism and a scraper mechanism. A sensor moving mechanism is provided on the frame above the slurry disk 11 and perpendicular to the moving direction of the slurry disk 11. The sensor moving mechanism includes: two support columns 12 arranged on both sides of the slurry disk 11 and a mounting cross plate 13 installed on the two support columns 12 and spanning the slurry disk 11. A transverse guide rail 5 is provided on the mounting cross plate 13. 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 a warning module. The slide 71 is driven by the transverse driving mechanism to carry the slurry thickness detection sensor 7 to move back and forth laterally along the transverse guide rail 5.

[0026] 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.

[0027] As another embodiment, the transverse driving mechanism includes a servo motor, a transmission gear and a ball screw mounted on the mounting transverse plate 13, and the slide seat 71 is connected to the ball screw.

[0028] As another embodiment, the transverse driving mechanism includes a cylinder and a piston rod installed on the mounting transverse plate 13, and the slide seat 71 is connected to the piston rod.

[0029] In the 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 on the two support columns 12.

[0030] The slurry thickness detection sensor 7 adopts an optical fiber 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 adopts a sound warning module.

[0031] like Figure 1 As shown, a position sensor 6 is installed on the installation horizontal 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 installed on the installation horizontal plate 13 to limit the left and right movement range of the entire slurry thickness sensor 7 at the hardware level, and a limit stopper 72 that cooperates with the position sensor 6 is provided on the slide seat 71.

[0032] like Figure 1 As shown, a drag chain 9 is installed on the installation cross plate 13 to protect the line from being worn during continuous movement. One end of the drag chain 9 is connected to the installation cross plate 13 , and the other end of the drag chain 9 is connected to the slide seat 71 .

[0033] Working principle of the device for slurry spreading, slurry line drawing and thickness parallel detection of the end-capping plate of the present invention: like Figure 1 As shown, the device is fixed on the end-sealed pulp disc and moves forward and backward with the pulp disc ( Figure 1 , Figure 4 The moving direction 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 relatively forward, backward, left and right, the slurry thickness detection sensor 7 will eventually move out of a plurality of 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 uneven thickness of the slurry is detected, a sound or light alarm will be issued.

[0034] like Figure 1 As shown, the servo motor 1 drives the reducer 2 to fix the synchronous wheel 3 to rotate, 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 accordingly.

[0035] In a preferred embodiment of the device of the present invention, the slurry thickness detection sensor 7 uses an optical fiber sensor, which is composed of a light source, an optical fiber, a detector, and a signal processor. When in use, the optical fiber sensor first emits an infrared beam, and the slurry on the slurry disk 11 reflects a part of the light after encountering the infrared beam, and the detector inside the slurry thickness detection sensor 7 receives the reflected light. The received reflected light is converted into a digital signal by the signal processor for output, so that the change of the slurry thickness can be understood in real time and in detail.

[0036] 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 installing the entire mechanism, the parallelism between the entire mechanism and the slurry 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 disk 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 always move up and down against the entire mounting cross plate 13, thereby fine-tuning the parallelism between the entire mounting cross plate 13 and the slurry disk 11, so that the slurry thickness detection sensor 7 can more accurately detect the thickness of the slurry.

[0037] 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, a drag chain 9 needs to be installed to protect the line from constant movement and wear.

[0038] Figure 1 The structure and connection relationship of the slurry spreading and slurry line drawing and thickness parallel detection device of the end plate of the present invention are only briefly shown, but only to show 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 the transmission device. Therefore, this embodiment Figure 1 The display is not to be regarded as limiting the only structure and connection relationship of the present invention.

[0039] The innovation 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.

[0040] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
