Description

Technical Field

[0001] This utility model relates to the technical field of AB glue drilling and scraping machines, specifically to an AB glue drilling and scraping machine. Background Technology

[0002] In the field of AB glue water drilling, traditional glue scraping equipment generally suffers from problems such as insufficient glue layer filling density and residual air bubbles. In the existing technology, glue scraping machines mostly adopt a single scraping process, and the glue is directly scraped flat after being poured in, which makes it impossible for air in the template hole to be effectively discharged. Especially in complex water drilling groove structures, air bubble defects are easily formed, which seriously affect the bonding strength and appearance quality of the glue after curing. In order to solve the above problems, this utility model provides an AB glue water drilling glue scraping machine. Utility Model Content

[0003] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide an AB glue drilling and scraping machine that uses negative pressure space to promote the expulsion of air from the hole, and performs secondary scraping after the air has dissipated, replenishing the glue while further compacting the glue.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: This utility model provides an AB glue drilling and scraping machine, comprising:

[0005] A base, used to fix the template;

[0006] The glue dispensing head is mounted on the base via a drive unit and can move along the long and short sides of the base.

[0007] The adhesive scraping part is mounted on the drive unit and slides along the long side of the base;

[0008] The glue scraping section scrapes glue twice during operation, and between the two scraping times, the air remaining in the template hole is extracted by negative pressure.

[0009] Preferably, the scraping part includes:

[0010] A substrate, which is mounted on a drive unit;

[0011] The first scraper is fixedly connected to the substrate;

[0012] The second scraper is fixedly connected to the substrate;

[0013] The first scraper is located between the second scraper and the substrate, and a negative pressure space is formed between the first scraper and the second scraper.

[0014] Preferably, the first scraper is provided with an adhesive inlet communicating with the negative pressure space above it.

[0015] Preferably, an air extraction port is provided above the second scraper and on the substrate, the air extraction port is connected to an air extraction frame fixedly installed on the substrate, and the air extraction frame is connected to an external negative pressure device.

[0016] Preferably, the upper side of the first and second scrapers facing the forward direction is a wedge-shaped surface, and the lower side is a flat surface.

[0017] Preferably, the lower end of the substrate is inclined away from the dispensing head.

[0018] Preferably, the substrate is made of an elastic material and has a pressing force that presses the first and second scrapers downward.

[0019] Preferably, the driving unit includes:

[0020] Two long-side screws are respectively installed in the frames provided on both sides of the base, and the long-side screws are respectively driven by the corresponding long-side motors;

[0021] A support frame is installed between two frames and is threadedly connected to two long-side screws respectively;

[0022] The dispensing head is slidably mounted on the support frame.

[0023] Preferably, a short-side screw is rotatably mounted inside the support frame, and the dispensing head is threadedly connected to the short-side screw via a fixing block fixedly connected thereto. The short-side screw is driven by a short-side motor mounted on the support frame.

[0024] Preferably, the base has a hollow structure, and the upper side of the base is provided with multiple suction ports, which are connected to an external negative pressure device through suction tubes fixedly connected to the base.

[0025] The beneficial effects of this utility model are as follows:

[0026] This invention, through the setting of a first scraper, a second scraper, and a negative pressure space, allows residual air in the hole to be expelled by negative pressure after the first scraping of adhesive. Then, the second scraper performs a second scraping of adhesive to replenish the air-expelled hole, thereby effectively avoiding residual air bubbles and ensuring the density of the adhesive filling.

[0027] The lower end of the substrate of this invention is inclined away from the dispensing head, and the substrate is made of an elastic material. Through this design, the first and second squeegees can maintain a stable contact pressure with the template, ensuring consistent glue thickness and thus improving the stability of the glue application process.

[0037] 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.

[0038] This utility model provides an AB glue drilling and scraping machine, such as... Figures 1 to 6 As shown.

[0039] Example 1:

[0040] An AB glue drilling and scraping machine includes a base 1, a drive unit on the base 1, a glue dispensing head 2 and a scraping part mounted on the drive unit, the drive unit can drive the glue dispensing head 2 to move precisely along the long side and short side of the base 1, and the drive unit can drive the scraping part to move along the long side of the base 1.

[0041] The drive unit includes two frames 10, which are respectively installed on both sides of the base 1. A long-side screw 9 is rotatably installed inside each of the two frames 10, and the two long-side screws 9 are driven by corresponding long-side motors 15. The two long-side motors 15 start and stop synchronously. The two long-side motors 15 are respectively installed on the corresponding frames 10. A support frame 11 is provided between the two frames 10. The two ends of the support frame 11 extend into the interior of the two frames 10 and are threadedly connected to the two long-side screws 9. The rotation of the motor shaft of the long-side motor 15 can drive the long-side screw 9 to rotate, so that the support frame 11 can slide along the long side of the frame 10 in the direction of the long side of the base 1.

[0042] A short-side screw 12 is rotatably mounted inside the support frame 11. The short-side screw 12 is connected to the motor shaft of the short-side motor 14 mounted on the support frame 11 via a synchronous belt. Both the short-side screw 12 and the motor shaft of the short-side motor 14 are fixedly connected to synchronous pulleys. The synchronous belt and the synchronous pulleys are meshed together. The rotation of the motor shaft of the short-side motor 14 can drive the short-side screw 12 to rotate. A fixing block 13 is fixedly connected to the dispensing head 2. The fixing block 13 is slidably mounted inside the support frame 11 and is threadedly connected to the short-side screw 12. The rotation of the short-side screw 12 can drive the dispensing head 2 to slide in the short-side direction of the base 1 through the fixing block 13.

[0043] Example 2:

[0044] The squeegee section includes a substrate 3. The upper end of the substrate 3 is fixedly connected to the support frame 11, and the lower end is inclined away from the dispensing head 2. The substrate 3 is made of an elastic material (such as elastic plastic). The lower end of the substrate 3 is fixedly connected to a first squeegee 4 and a second squeegee 5. Under the elastic force of the substrate 3, the first squeegee 4 and the second squeegee 5 always maintain a stable contact pressure with the template, so that the thickness of the squeegee can be kept consistent, thereby ensuring the stability of the squeegee operation.

[0045] A negative pressure space is formed between the first scraper plate 4 and the second scraper plate 5. An adhesive inlet 6 is provided above the first scraper plate 4, and an air extraction port 7 is provided above the second scraper plate 5 and located on the substrate 3. The air extraction port 7 is connected to an external negative pressure device through an air extraction frame 8. The upper front side of the first scraper plate 4 and the second scraper plate 5 is a wedge-shaped surface, and the lower side is a flat surface, which facilitates the flow of adhesive during scraping.

[0046] During operation, the drive unit moves the scraping unit. At this time, the first scraping plate 4 will first perform the first scraping operation. Then, as the scraping unit moves, the negative pressure space will move to the top of the template hole after the first scraping plate 4 has scraped the glue. If there is residual air in the hole, the air will be extracted under the action of negative pressure. At the same time, the glue scraped by the first scraping plate 4 will enter the interior of the negative pressure space through the glue inlet 6 and be scraped back into the template hole where the air has been discharged by the second scraping plate 5. This can further fill the glue, effectively avoid the residue of air bubbles, and ensure the uniformity of the glue layer and the density of the filling.

[0047] The upper side of the squeegee 5 can collect excess glue, so that excess glue will not affect the squeegee effect.

[0048] Example 3:

[0049] The base 1 has a hollow structure, and the upper side of the base 1 is provided with multiple suction ports 16. The suction ports 16 are connected to the cavity inside the base 1. The cavity is connected to the suction pipe 17 fixedly connected to the base 1. The suction pipe 17 is connected to the external negative pressure device. When in use, the external negative pressure device is activated, so that negative pressure can be generated above the suction ports 16, which can fix the template placed on the base 1 and ensure the stability of the template when applying glue.

[0050] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
