Description

Technical Field

[0001] This utility model relates to the field of LCD and OLED screen processing technology, specifically to a glue scraping head mechanism. Background Technology

[0002] Squeegee application is a process that involves applying electronic adhesives, oils, or other liquids to a product to achieve adhesion. Using a squeegee head ensures uniform adhesive thickness, reduces defect rates, and lowers process costs, among other advantages.

[0003] Using a scraper head to perform the scraping operation can effectively ensure the consistency of adhesive thickness, reduce product defect rates, and cut costs in the production process. However, the existing scraping operation has a significant drawback: it is difficult to maintain a stable and uniform adhesive output during the scraping process. This problem directly leads to a significant reduction in scraping accuracy, which in turn seriously interferes with the accuracy of subsequent product bonding processes, negatively impacting the overall product quality.

[0004] In view of this, it is necessary to improve the existing scraper head mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a glue scraping head mechanism to solve the problem of uneven glue dispensing, which seriously affects the glue scraping accuracy and subsequent bonding accuracy.

[0006] To solve the above technical problems, this utility model provides the following solution: A scraping head mechanism of this utility model includes:

[0007] The scraper head assembly has internal flow channels;

[0008] An adjustment component capable of adjusting the position of the scraper head assembly;

[0009] A glue tube connected to the glue scraper head assembly and communicating with the flow channel.

[0010] Furthermore, the scraper head assembly includes:

[0011] An upper component having a downwardly stepped surface, the stepped surface being slotted to form the flow channel, the flow channel having a downwardly opening;

[0012] The lower component covers the stepped surface and covers the flow channel and the groove, and an adhesive outlet is formed between the lower component and the groove.

[0013] Furthermore, the slot is configured as an inclined slot.

[0014] Furthermore, the lower component and the flow channel have a side leakage prevention structure, which includes a groove provided on the stepped surface, the groove surrounding the upper side and left and right sides of the flow channel, and a sealing gasket is embedded in the groove, the sealing gasket being pressed by the lower component.

[0015] Furthermore, the inner side of the flow channel is provided with a connection hole.

[0016] Furthermore, the adjustment component includes:

[0017] The connector is an L-shaped structural component, with one end horizontally connected to and sealing the connecting hole, and the other vertical end facing upwards.

[0018] A left-right adjustment component is connected to the vertical end of the connector. The left-right adjustment component has a clamping slot. The vertical end of the connector enters the clamping slot and is fixed to the left-right adjustment component. The vertical end of the connector and the left-right adjustment component adjust the left and right positions of the connector through left-right adjustment holes and adjustment screws.

[0019] The front and rear adjustment parts adjust the front and rear positions of the left and right adjustment components through the front and rear adjustment holes and adjustment screws.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. Significantly improves glue application accuracy: Through the carefully designed internal flow channel structure of the glue application head assembly, especially the flow channel formed by the groove on the stepped surface of the upper component and the glue outlet formed by its cooperation with the lower component, the flow path of the glue can be effectively standardized, greatly improving the uneven glue application in the existing technology. This ensures that the glue can be squeezed out from the glue outlet at a stable and uniform flow rate and accurately applied to the product surface, significantly improving the accuracy of the glue application process and meeting the stringent requirements of LCD and OLED screen processing for high-precision glue application.

[0022] 2. Strongly Guaranteed Bonding Accuracy: A stable and uniform adhesive application effect lays a solid foundation for subsequent bonding processes. A uniform adhesive layer thickness ensures more even stress distribution on product components during bonding, avoiding bonding deviations caused by inconsistent adhesive layer thickness. This effectively improves product bonding accuracy, reduces defective products due to poor bonding, and enhances overall product quality and yield.

[0023] 3. Optimized Adjustment Function: The adjustment component allows for flexible adjustment of the scraper head assembly position according to different processing requirements. In actual production, facing products of different sizes and shapes, as well as diverse scraping process requirements, operators can easily change the position of the scraper head assembly through the adjustment component, ensuring that the scraping operation can always be carried out accurately and efficiently, significantly enhancing the adaptability of the scraper head mechanism to complex production environments.

[0024] 4. Reduced production costs: On the one hand, stable glue application and bonding accuracy reduce rework costs and material waste caused by defective products, thus lowering the scrap rate; on the other hand, the flexibility and adaptability brought by the adjustment components reduce the cost of replacing equipment or carrying out large-scale equipment modifications due to the inability of the equipment to adapt to different products. This reduces the overall cost in the production process from multiple dimensions and improves production efficiency and economic benefits. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] Example 1: The specific structure of this utility model is as follows:

[0031] Please refer to the appendix. Figure 1-2 The present invention provides a scraper head mechanism, comprising a scraper head assembly 4 having an internal flow channel 413, an adjustment component capable of adjusting the position of the scraper head assembly, and a glue cylinder 5 connected to the scraper head assembly and communicating with the flow channel 413.

[0032] The scraper head assembly 4 includes:

[0033] The upper component 41 has a downwardly arranged stepped surface 411, the stepped surface 411 being slotted to form the flow channel 413, the flow channel 413 having a downwardly arranged slot 415, and the lower corner of the upper component 41 facing away from the flow channel 413 being chamfered.

[0034] The lower component 42 covers the stepped surface 411 and covers the flow channel 413 and the groove 415, and an adhesive outlet is formed between the lower component 42 and the groove 415.

[0035] The slot 415 is set as an inclined slot. After the lower component 42 is fixed, the glue outlet formed between the lower cover 42 and the inclined slot is narrower and the glue outlet cavity formed changes from wide to narrow, which effectively ensures the glue dispensing speed and avoids excessive glue spraying.

[0036] A leak-proof structure is provided between the lower component 42 and the flow channel 413. This leak-proof structure includes a groove 412 provided on the stepped surface 411. The groove 412 surrounds the upper and left and right sides of the flow channel 413. A sealing gasket is embedded in the groove 412. The sealing gasket is pressed tightly by the lower component 42 to prevent glue leakage. A connection hole 414 is provided on the inner side of the flow channel 413.

[0037] The adjustment component includes:

[0038] Connector 3 is an L-shaped structural component, one end of which is horizontally connected to the connecting hole 414 and blocks the connecting hole, while the other vertical end is set upwards.

[0039] The left and right adjustment component 2 is connected to the vertical end of the connector 3. The left and right adjustment component 2 has a clamping slot. The vertical end of the connector 3 enters the clamping slot and is fixed to the left and right adjustment component 2. The vertical end of the connector 3 and the left and right adjustment component 2 adjust the left and right positions of the connector 3 through the left and right adjustment hole and the adjustment screw.

[0040] The front-to-back adjustment part 1 adjusts the front-to-back position of the left-to-right adjustment component 2 through the front-to-back adjustment hole and adjustment screw.

[0041] The glue-dispensing end of the scraper head assembly 4 of this invention is leveled with the product surface by adjusting the front and rear parts 1 and the left and right adjustment components 2, and a certain distance is reserved between the scraper head assembly 4 and the pre-coated surface of the product. The glue in the glue cylinder 5 is squeezed out by pressure, and the glue flows along the flow channel to the groove 415, and then is sprayed out from the glue outlet at the groove to the product surface. The glue outlet of this invention is a long and narrow opening, which can achieve efficient glue coating on the entire surface of the product.

[0042] In summary, this invention can significantly improve the precision of glue application: through the carefully designed internal flow channel structure of the glue application head assembly, especially the flow channel formed by the groove on the stepped surface of the upper component and the glue outlet formed in cooperation with the lower component, the flow path of the glue can be effectively standardized, greatly improving the uneven glue output in the prior art. This ensures that the glue can be squeezed out from the glue outlet at a stable and uniform flow rate and accurately applied to the product surface, significantly improving the precision of the glue application process and meeting the stringent requirements of LCD and OLED screen processing for high-precision glue application.

[0043] This invention effectively ensures bonding accuracy: the stable and uniform adhesive application directly lays a solid foundation for subsequent bonding processes. A uniform adhesive layer thickness allows for more even force distribution on product components during bonding, avoiding bonding deviations caused by inconsistent adhesive layer thickness. This effectively improves product bonding accuracy, reduces defective products due to poor bonding, and enhances overall product quality and yield.

[0044] This invention optimizes the adjustment function: the adjustment component allows the position of the scraper head assembly to be flexibly adjusted according to different processing requirements. In actual production, facing products of different sizes and shapes, as well as diverse scraping process requirements, operators can easily change the position of the scraper head assembly by adjusting the component, ensuring that the scraping operation can always be carried out accurately and efficiently, significantly enhancing the adaptability of the scraper head mechanism to complex production environments.

[0045] This invention reduces production costs: on the one hand, stable glue application and bonding accuracy reduce rework costs and material waste caused by defective products, thus lowering the scrap rate; on the other hand, the flexibility and adaptability brought by the adjustment components reduce the cost of replacing equipment or carrying out large-scale equipment modifications due to the inability of the equipment to adapt to different products. It reduces the overall cost in the production process from multiple dimensions and improves production efficiency and economic benefits.
