Description

Technical Field

[0002] At present, the old-fashioned dispensing methods such as herringbone dispensing or Z-shaped dispensing tracks are still used in the market to bond screen glass and screens. However, the old-fashioned dispensing method can only be used in situations where the uniformity of glue thickness distribution is not required or the glue path track is fixed. If the old-fashioned dispensing method is still used in situations where the uniformity of glue thickness distribution is required to be high, it will lead to problems such as thickness tolerance or inconsistent uniformity of glue output thickness, which will lead to a low pass rate of dispensed glue products.

[0003] The utility model will provide a slit gluing device and a three-axis slit gluing machine, which are used to solve the problems of inconsistent glue thickness uniformity and thickness tolerance in the prior art. The equipment will use a slit gluing device for slit gluing. The advantage of using slit gluing is that the glue is evenly discharged and the glue thickness remains consistent, there is no problem of thickness tolerance, and controlling the width of the slit can not only ensure the control of the glue discharge rate, but also ensure the glue discharge speed.

[0066] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0067] See also Figure 1-Figure 9 Now, the utility model discloses a slit glue coating device, which is used for gluing precision products, such as Figure 2, including a vertical adjustment component 41, a horizontal adjustment component 42, a slit glue coating head 43, a connecting block 44 and a connecting plate 45. The top of the slit glue coating head 43 is provided with a connecting block 44, and the width of the slit is adjustable, which is composed of two clamping plates. The connecting block 44 is provided with a through hole. The slit glue coating head 43 is screwed and installed on the left side of the connecting plate 45. The glue is introduced into the slit through the through hole. The bottom of the vertical adjustment component 41 is hingedly provided with a horizontal adjustment component 42. The slit width of the slit glue coating head 43 can be adjusted for glue discharge speed and glue discharge amount of different glue thicknesses; and the vertical adjustment component 41 and the horizontal adjustment component 42 are used to adjust the glue coating angle of the slit glue coating head 43.

[0068] In this embodiment, if Figure 3 The vertical adjustment component 41 includes a connecting piece 411, a vertical adjustment spring 412 and a vertical micrometer 413. The horizontal adjustment component 42 is hingedly installed in the middle of the connecting piece 411. The top of the vertical adjustment spring 412 is connected to the connecting piece 411, and the bottom is against the horizontal adjustment component 42. The vertical micrometer 413 passes through the connecting piece 411 and is against the horizontal adjustment component 42.

[0069] In this embodiment, the vertical micrometer 413 is arranged at one end of the connecting piece 411, and the vertical adjustment spring 412 is installed at the other end of the connecting piece 411. When the knob of the vertical micrometer 413 is turned, the length of the vertical micrometer 413 increases, compressing the length of the vertical adjustment spring 412, thereby causing the slit coating head 43 to rotate in the vertical direction and maintain a stable posture under the elastic force of the vertical adjustment spring 412.

[0070] In a specific embodiment, a horizontal adjustment component 42 is hingedly provided on the right side of the connecting plate 45 , and the horizontal adjustment component 42 passes through the connecting plate 45 and abuts against the slit glue coating head 43 .

[0071] In this embodiment, the horizontal adjustment assembly 42 includes a plate body 421, a horizontal micrometer 422 and a horizontal adjustment spring 423. The middle part of the plate body 421 is hinged to the connecting plate 45, and the top part is hinged to the connecting piece 411. The horizontal micrometer 422 passes through the plate body 421 and abuts against the connecting plate 45. The head end of the horizontal adjustment spring 423 abuts against the connecting plate 45, and the tail end abuts against the plate body 421. The horizontal adjustment assembly 42 is connected to the connecting plate 45, and the connecting plate 45 is connected to the slit glue head 43, so the horizontal angle of the slit glue head 43 can be adjusted through the horizontal adjustment assembly 42, and the adjustment of the horizontal angle is achieved by twisting the horizontal micrometer 422. The horizontal adjustment spring 423 has the same effect as the vertical adjustment spring 412, and is used to prevent the connecting plate 45 from tilting.

The DAM gluing device 6 is used to apply glue to the outer periphery of the glass plate to form a fence around the outer periphery of the glass plate to prevent the glue from flowing out during the slit gluing. After the outer periphery gluing is completed, the slit gluing head 43 is used to fully coat the glass plate. The detection component 5 uses a distance sensor to detect the distance between the glass plate and the sensor. If the detection distance exceeds the set limit value, it means that the glass plate is placed unevenly and tilted, and needs to be rearranged. The frame 8 can perform Y-axis displacement.

[0073] In a specific embodiment, Figure 5 The mounting part 3 includes a connecting frame 31 and a lifting assembly 32. The left side of the upgrading assembly 32 is connected to the glue mixing device 1 by transmission, and the lifting assembly 32 is screwed and installed on the inner side of the connecting frame 31. The mounting part 3 is a central part, and most of the devices are installed on the connecting frame 31 in the mounting part 3; the lifting assembly 32 in the mounting part 3 is used to adjust the position of the glue mixing device 1. By adjusting the lifting assembly 32, the glue mixing assembly 2 is driven to rise and fall, so as to adjust the depth of the rubber hose inserted into the slit glue coating device 4.

[0074] In a specific embodiment, Figure 7 The glue storage device 2 includes a mounting plate 21, a liquid outlet assembly 22, a pressure reducing gauge assembly 23 and a glue storage tank 24. The mounting plate 21 is screwed on the left side of the glue storage tank 24, and the glue storage tanks 24 are arranged in pairs. The mounting member 3 is screwed on the right side of the mounting plate 21. The glue storage tanks 24 are screwed on the top of the liquid outlet assembly 22, and the liquid outlet assembly 22 is arranged in pairs. The pressure reducing gauge assembly 23 is arranged in pairs outside the glue storage tank 24. A capacitive sensor is connected to the right side of the glue storage tank 24. The capacitive sensor and the pressure reducing gauge assembly 23 jointly detect the liquid outlet pressure. The glue in the glue storage tank 24 is discharged through the liquid outlet assembly 22, so that the glue flows into the glue mixing device 1.

[0075] Based on the previous embodiment, Figure 6The glue mixing device 1 includes a pushing component 11, a glue feeding component 12, a liquid infusion pipeline 13 and a glue mixing component 14. The right side of the glue mixing component 14 is connected to the mounting part 3 in a transmission manner. The lower part of the glue mixing component 14 is connected to a slit glue coating head 43. The lower part of the liquid infusion pipeline 13 is connected to the glue mixing component 14. The liquid infusion pipeline 13 is arranged in pairs. The lower part of the pushing component 11 is connected to the liquid infusion pipeline 13. The pushing component 11 is arranged in pairs. The pushing component 11 uses a driving motor to push the glue in the liquid infusion pipeline 13 into the glue mixing component 14. The glue feeding component 12 is arranged in pairs outside the liquid infusion pipeline 13. The glue in the glue storage device 2 flows into the liquid infusion pipeline 13 through the glue feeding component 12, and then the glue is fed into the glue mixing component 14 through the pushing component 11. The glue mixing component 14 will feed the mixed glue into the slit glue coating device 4.

[0076] In a specific embodiment, Fig. 9 The displacement drive device 7 includes an X-axis drive 71 and a Z-axis drive 72. The front of the Z-axis drive 72 is screwed with a mounting member 3, and the front of the X-axis drive 71 is connected to the Z-axis drive 72. Both the Z-axis drive 72 and the X-axis drive 71 use a driving motor to drive the slider to move on the slide rail. The Z-axis drive 72 can be used for gluing glass plates of different thicknesses, because the Z-axis drive 72 can send the slit gluing device 4 to the most suitable height for gluing; while the X-axis drive uses a servo motor to control the moving speed, which can make the slit gluing device 4 move forward at a uniform speed, making the gluing more uniform.

[0077] In a specific embodiment, the DAM gluing device 6 includes a pneumatic component 61, a glue storage tube 62 and a gluing head 63. The right side of the pneumatic component 61 is screwed with the mounting member 3, the right side of the glue storage tube 62 is screwed with the pneumatic component 61, and the glue storage tube 62 is connected to the top of the gluing head 63. The pneumatic component 61 can drive the DAM gluing device 6 to rise and fall to ensure that the gluing is carried out at the best height; and the glue storage tube 62 will send the glue to the gluing head 63 for gluing.

[0078] On the basis of the previous embodiment, the glue coating head 63 is composed of four baffles and a glue outlet. When in use, the four baffles rotate to make the glue coating uniform and increase the glue coating area. Because the DAM glue coating device 6 is to coat the periphery of the glass plate with glue, a fence must be formed around the periphery of the glass plate to prevent the glue from flowing out. Therefore, the four baffles are rotated to coat the periphery with glue, which can make the glue coating more uniform, and the fence formed is higher, which can better ensure that the glue will not flow out.

[0079] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
