Description

Technical Field

[0001] This utility model relates to the field of semiconductor chip production and testing equipment, and in particular to a feeding mechanism for an automated cleaning equipment for conductive adhesive. Background Technology

[0002] In semiconductor chip manufacturing, functional and performance testing is a crucial process for quality control. To prevent chip damage, an increasing number of manufacturers and institutions are replacing elastic pin plates with conductive adhesive in test fixtures and equipment used to connect chips and test circuit boards. During production testing, prolonged or high-frequency use can leave contaminants such as particles and dust on the conductive adhesive. After a certain period, cleaning is necessary. Currently, there are generally two methods for cleaning conductive adhesive: one is chemical cleaning with a brush or cotton swab, and the other is ultrasonic cleaning. Cleaning with chemicals and brushes or cotton balls can easily damage the gold wires used for conduction within the adhesive. Ultrasonic cleaning is costly and complex, and both methods have low automation levels and are inefficient for cleaning large batches of conductive adhesive in large-scale production testing. Utility Model Content

[0003] This invention provides a feeding mechanism for an automated conductive adhesive cleaning device, solving the problems of low automation and low efficiency in batch cleaning operations in existing conductive adhesive cleaning systems.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a feeding mechanism for an automated conductive adhesive cleaning device, comprising an elastically deformable adhesive part for sticking and cleaning conductive adhesive, a transmission part for driving the adhesive part to move, and a feeding mechanism for automatically removing the adhesive part from the transmission part. The feeding mechanism includes a feeding fixing plate, a feeding limiting plate, a pushing and cutting feeding part, a scraping mechanism, and a feeding driving mechanism. The feeding fixing plate is provided with a rectangular through-hole first groove, and the feeding limiting plate is fixedly mounted on the feeding fixing plate. The plate frame covers the first groove. A vertically penetrating limiting hole is provided on the unloading limiting plate at a position corresponding to the first groove to limit the connection between the transmission part and the adhesive part. The pushing-cutting unloading part is fixedly connected to the unloading drive mechanism and is driven by the unloading drive mechanism to reciprocate horizontally below the limiting hole in the first groove to perform a pushing-cutting action. The scraping mechanism is located below the unloading limiting plate and on the side away from the limiting hole from the pushing-cutting unloading part. The scraping mechanism includes a scraper plate elastically configured to scrape the adhesive part on the pushing-cutting unloading part. This achieves automated unloading of the adhesive part on the transmission part, effectively improving cleaning efficiency.

[0005] Furthermore, the upper end of the scraper is configured as a smooth guide arc surface facing the side of the pushing and cutting section. This facilitates the pushing and cutting end of the pushing and cutting section passing through the upper end of the scraper.

[0006] Furthermore, a cutting and pushing bevel is provided on the lower side of the end of the push-cutting and unloading part near the limiting hole, and the height of the vertical surface on the upper side of the end of the push-cutting and unloading part near the limiting hole is between 1 mm and 2 mm. This facilitates subsequent cleaning of the adhesive parts on the push-cutting and unloading part.

[0007] Furthermore, the outer surfaces of the material feeding fixing plate, the material feeding limiting plate, the pushing and cutting part, and the scraping mechanism are all coated with an anti-stick coating. This prevents adhesive parts from sticking to the material feeding structure and affecting subsequent operations.

[0008] Furthermore, the height of the first groove is greater than the thickness of the cutting and unloading section, and a limiting boss is provided on the first groove of the unloading fixing plate near the end of the cutting and unloading section to limit the horizontal movement of the cutting and unloading section. This prevents residue or structural jamming on the cutting and unloading transmission section due to force displacement during long-term use.

[0009] Furthermore, the scraping mechanism also includes a fixed base plate and an elastic element. The upper surface of the fixed base plate is provided with a rectangular limiting cavity for limiting the vertical movement of the scraper plate. The bottom of the rectangular limiting cavity is provided with multiple lower limiting holes. The bottom of the scraper plate is provided with an upper limiting hole corresponding to the lower limiting hole. The elastic element includes multiple scraping drive springs with their upper and lower ends respectively located in the corresponding upper and lower limiting holes. When the upper end of the scraper plate abuts against the lower end surface of the feeding limiting plate, the scraping drive springs are in an effectively compressed state. This design is simple and effectively cleans the push-cut feeding section after the feeding and bonding parts have been completed, facilitating subsequent feeding operations.

[0010] Furthermore, a first waste material collection cavity is provided on the side of the scraper plate away from the push-cutting section on the fixed base plate. This cavity collects and processes the waste adhesive parts, preventing contamination of the material feeding structure and affecting subsequent feeding operations.

[0011] Furthermore, a second waste disposal cavity is provided on the side of the scraper plate near the push-cutting section on the fixed base plate. The second waste disposal cavity is located below the first trough, and the bottom of the first trough is provided with a downward-through waste drain hole. This collects and processes the adhesive parts that fall into the first trough, preventing contamination of the feeding structure and affecting subsequent feeding operations.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1 The illustrated automatic conductive adhesive cleaning equipment includes a feeding mechanism for a conductive adhesive that can be elastically deformed, a transmission part for driving the adhesive part to move, and a feeding mechanism for automatically removing the adhesive part from the transmission part. The feeding mechanism includes a feeding fixing plate 110, a feeding limiting plate 120, a pushing and cutting feeding part 130, a scraping mechanism 140, and a feeding driving mechanism 150. The feeding fixing plate 110 has a rectangular through-hole first groove 111. The feeding limiting plate 120 is fixedly mounted on the feeding fixing plate 110 and covers the first groove 111. The plate 120 is provided with a vertically penetrating limiting hole 121 at a position corresponding to the first groove 111 for limiting the connection between the transmission part and the adhesive part. The push-cutting part 130 is fixedly connected to the feeding drive mechanism 150 and is driven by the feeding drive mechanism 150 to move horizontally back and forth in the first groove 111 below the limiting hole 121 to perform a push-cutting action. The scraping mechanism 140 is provided below the feeding limiting plate 120 and is located on the side of the limiting hole 121 away from the push-cutting part 130. The scraping mechanism 140 includes a scraper plate 141 that is elastically provided for scraping the adhesive part on the push-cutting part 130.

[0019] In this specific embodiment, the unloading drive mechanism 150 is a cylinder. In specific implementations, the unloading drive mechanism 150 can also be a linear drive mechanism composed of a screw assembly and a motor, or other drive mechanisms with linear drive functions. The unloading limit plate 120 is fixedly mounted on the unloading fixing plate frame 110 through the outer threaded holes and bolt structure. The transmission part is an adapter rod, and the adhesive part is a custom-made double-sided silicone with a thickness greater than 2.5 mm purchased from the market and cut to the required size according to actual needs, which is low in cost.

[0020] In practice, the transmission unit is moved into the limiting hole 121 and is horizontally limited. At this time, the main body of the adhesive part mating with the transmission unit is located in the first groove 111 (the thickness of the adhesive part in the limiting hole 121 is no more than 0.1 mm. This thickness is determined by the overall precision of the equipment structure. With higher precision, the thickness of the adhesive part in the limiting hole 121 can be made smaller. The adhesive part generally adopts an overall thickness of at least 2.5 mm, and the thickness in the limiting hole 121 is no more than 0.1 mm. During debugging, this is sufficient to push the cutting and unloading part 130 to cut the adhesive part off the transmission unit). Then, the feeding drive mechanism 150 drives the pushing and cutting feeding part 130 to move horizontally below the limiting hole 121 in the first groove 111 to perform a pushing and cutting action, pushing and cutting the adhesive part off the transmission part. During this process, after the pushing and cutting end of the feeding drive mechanism 150 drives the pushing and cutting feeding part 130 to pass the upper end of the scraper 141, during the reset process, the elastically set scraper 141 scrapes off the adhesive part pushed and cut off from the pushing and cutting feeding part 130, so that the pushing and cutting feeding part 130 can proceed to the next operation; thus realizing the automated feeding of the adhesive part on the transmission part and effectively improving the cleaning efficiency.

[0021] Based on the above, such as Figure 1 , Figure 2 and Figure 4 As shown, the upper end of the scraper 141 is configured as a smooth guide arc surface 148 facing the side of the push-cutting and unloading section 130. In a specific implementation, this facilitates the unloading drive mechanism 150 to drive the push-cutting end of the push-cutting and unloading section 130 to push the upper end of the scraper 141, causing the scraper 141 to elastically move downward and pass through its upper end.

[0022] Based on the above, such as Figures 1 to 3As shown, a cutting and pushing bevel 131 is provided on the lower side of the end of the push-cutting and unloading part 130 near the limiting hole 121. The height of the vertical surface on the upper side of the end of the push-cutting and unloading part 130 near the limiting hole 121 is between 1 mm and 2 mm. In specific implementations, the thickness of the adhesive part is generally between 2.5 mm and 3.5 mm. Setting the height of the vertical surface on the upper side of the end of the push-cutting and unloading part 130 near the limiting hole 121 to between 1 mm and 2 mm avoids directly cutting off the adhesive part during the pushing and cutting process, which would result in residue of the adhesive part on the transmission part and affect the cleaning effect after the new adhesive part is connected to the transmission part. The cutting and pushing bevel 131 ensures that the main body of the pushed-off adhesive part is located in the adhesive part, which facilitates the subsequent cleaning of the adhesive part on the push-cutting and unloading part 130.

[0023] Based on the above, such as Figures 1 to 4 As shown, the outer surfaces of the feeding fixing plate 110, the feeding limiting plate 120, the pushing and cutting feeding part 130, and the scraping mechanism 140 are all coated with an anti-stick coating. In this specific embodiment, the anti-stick coating is a sprayed Teflon coating, forming a smooth surface and achieving hydrophobic, oleophobic, and non-stick effects; preventing adhesive parts from sticking to the structure of the feeding fixing plate 110, the feeding limiting plate 120, the pushing and cutting feeding part 130, and the scraping mechanism 140, thus affecting subsequent operations.

[0024] Based on the above, such as Figures 1 to 3 As shown, the height of the first groove 111 is greater than the thickness of the cutting and unloading section 130. A limiting boss 112 is provided on the first groove 111 of the unloading fixing plate 110 near the end of the cutting and unloading section 130 to limit the horizontal movement of the cutting and unloading section 130. In specific implementations, the first groove 111 and the limiting boss 112 limit the cutting and unloading section 130, preventing residue or structural jamming on the cutting and unloading transmission section due to force displacement during long-term use.

[0025] Based on the above, such as Figure 1 , Figure 2 and Figure 4As shown, the scraping mechanism 140 also includes a fixed base plate 142 and an elastic element. The upper end surface of the fixed base plate 142 is provided with a rectangular limiting cavity 143 for limiting the vertical movement of the scraper plate 141. The bottom of the rectangular limiting cavity 143 is provided with a plurality of lower limiting holes 144. The bottom of the scraper plate 141 is provided with an upper limiting hole 145 corresponding to the lower limiting hole 144. The elastic element includes a plurality of scraping drive springs 146 with their upper and lower ends respectively in the corresponding upper limiting hole 145 and lower limiting hole 144. When the upper end of the scraper plate 141 abuts against the lower end surface of the unloading limiting plate 120, the scraping drive springs 146 are in an effective compressed state. In specific implementation, when the feeding drive mechanism 150 drives the pushing and cutting end of the feeding part 130 to pass over the upper end of the scraper plate 141, the cutting and pushing inclined surface 131 and the guide arc surface 148 interact, causing the scraper plate 141 to move vertically downward and drive the scraper drive spring 146 to be further compressed. In the subsequent reset process of the feeding drive mechanism 150 driving the pushing and cutting part 130, the scraper drive spring 146 drives the upper end of the scraper plate 141 to elastically contact the cutting and pushing inclined surface 131, scraping off the adhesive part on the cutting and pushing inclined surface 131. The structure is simple and achieves the cleaning of the feeding and cutting part 130 after the adhesive part has been fed, which facilitates the subsequent feeding operation.

[0026] Based on the above, such as Figure 1 , Figure 2 and Figure 4 As shown, a first waste material placement cavity 147 is provided on the side of the scraper plate 141 on the fixed base plate 142 away from the push-cutting and unloading section 130. In specific implementation, the waste adhesive parts are collected and processed to avoid contaminating the unloading structure and affecting subsequent unloading operations.

[0027] Based on the above, such as Figure 1 , Figure 2 and Figure 4 As shown, a second waste disposal cavity 149 is provided on the side of the scraper plate 141 on the fixed base plate 142 near the push-cutting and unloading section 130. The second waste disposal cavity 149 is located below the first trough 111, and a downward-through waste drain hole 113 is provided at the bottom of the first trough 111. In specific implementation, the adhesive parts that fall into the first trough 111 are collected and processed to avoid contaminating the unloading structure and affecting subsequent unloading operations.

[0028] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
