Description

Technical Field

[0001] This utility model relates to the field of pick and place machine technology, and in particular to an adhesive storage device for dipping adhesive and a pick and place machine. Background Technology

[0002] In optical communication products, surface mount technology (SMT) is a common process used to mount optical components such as lenses, mirrors, and gratings onto a ceramic substrate according to a light path refraction diagram, forming the desired optical path. During mounting, adhesive is typically applied precisely to the corresponding positions on the ceramic substrate, and the optical components are then attached. In actual mounting processes, for materials with high mounting requirements and large adhesive particles, a dipping adhesive method is used.

[0003] When using the glue-dip method, in order to ensure the stability of the glue amount, a glue tray and a glue scraper are usually used together. The horizontality of the glue scraper and the glue tray must be 0.002mm / m. The positioning and matching of the glue scraper and the glue tray have high requirements for processing and positioning accuracy, which makes the operation more difficult. Moreover, the glue layer thickness cannot be adjusted. Utility Model Content

The scraping part includes a scraping plate, guide plates disposed on both sides of the scraping plate, and a top plate connected to the scraping plate and the guide plates respectively. The scraping part is connected to the connecting part through the top plate. A glue storage groove is formed between the top plate, the scraping plate and the guide plates, and the depth of the glue storage groove near the scraping plate is less than the depth of the glue storage groove away from the scraping plate.

[0009] Optionally, the glue storage device for applying glue further includes a light-shielding component, which includes a support arm rotatably connected to the mounting base and a light-shielding plate connected to the support arm. The mounting base is also provided with a limiting member, which is used to limit the support arm so that when the support arm abuts against the limiting member, the light-shielding plate is located above the glue tray.

[0010] Optionally, the support arm includes a first arm and a second arm connected at right angles. The first arm is rotatably connected to the mounting base, and the second arm is connected to the light shield. The limiting member is a bolt, and the limiting member is threadedly connected to the mounting base. The light shield is provided with a clearance opening, which is used to avoid the glue scraper and the glue stick used to pick up glue.

[0011] Optionally, the adhesive storage device for dipping adhesive further includes a cleaning component and a cleaning belt winding component. The cleaning component is used to clean the adhesive stick. The cleaning component includes a gripper cylinder disposed on the bracket, and a first chuck and a second chuck connected to the gripper of the gripper cylinder. The cleaning belt winding component is used to make the cleaning belt pass through the first chuck and the second chuck in sequence, so as to clean the adhesive stick through the cleaning belt.

[0015] The beneficial effects of the glue storage device for applying glue provided in this embodiment are as follows: By connecting the drive motor mounted on the bracket to the rotating base, the rotating base rotates relative to the mounting base, causing the glue tray connected to the rotating base to rotate synchronously. This causes relative movement between the glue in the glue tray and the glue scraper, which smooths the glue and ensures the stability of the glue application rate. Furthermore, when adjusting the thickness of the smoothed glue, rotating the screw adjusts the distance between the glue scraper and the glue tray, allowing for flexible adjustment of the glue layer thickness. Simultaneously, the elastic element allows the top of the screw and the bottom of the blade holder to abut against each other, compensating for errors generated during processing and installation to a certain extent, reducing the requirements for processing and positioning accuracy, and thus reducing operational difficulty. Moreover, the screw is located between the blade holder and the mounting base and does not protrude above the glue tray, avoiding interference with normal glue application. By coordinating the glue scraping assembly and the height adjustment module, the thickness of the glue layer in the glue tray can be adjusted during glue application, and the height can be adjusted simply by turning the screw, which helps to reduce the difficulty of precision control during assembly and adjustment.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figure 1 As shown, this utility model embodiment provides a glue storage device 100 for applying glue, including: a bracket 110; a mounting base 120 disposed on the bracket 110; at least one rotating assembly 130, the rotating assembly 130 including a drive motor 132 and a rotating base 134 connected by transmission, the drive motor 132 being connected to the bracket 110, and the rotating base 134 being rotatably connected to the mounting base 120; a glue tray 140 connected to the rotating base 134, the glue tray 140 being used to hold glue and for a glue applicator to apply glue; and a glue scraping assembly 150 corresponding to the glue tray 140. The device includes a blade holder 152 slidably connected to the mounting base 120, a scraper blade 154 connected to the blade holder 152, an elastic element 156 connected between the blade holder 152 and the mounting base 120, and a height adjustment module 158. The scraper blade 154 is used to scrape the glue evenly. The height adjustment module 158 includes an adjusting nut 1582 disposed on the mounting base 120 and a screw 1584 threadedly connected to the adjusting nut 1582. The elastic element 156 is used to make the top of the screw 1584 abut against the bottom of the blade holder 152. When the screw 1584 is rotated, it is used to adjust the distance between the scraper blade 154 and the glue tray 140.

[0027] Specifically, the bracket 110 serves as the basic support component of the glue storage device 100 for dispensing glue, providing a platform for the installation and fixation of other components and ensuring the overall stability of the glue storage device 100. The mounting base 120, mounted on the bracket 110, is a crucial component connecting and supporting the rotating assembly 130, the glue scraping assembly 150, and other components, integrating multiple functional components to enable them to work collaboratively. The rotating assembly 130 includes a drive motor 132 and a rotating base 134, which are connected by a drive mechanism. The drive motor 132 is connected to the bracket 110, providing power for the rotation of the rotating base 134; the rotating base 134 is rotatably connected to the mounting base 120 and can rotate under the drive of the drive motor 132. The glue tray 140 is connected to the rotating base 134 and rotates along with the rotating base 134.

[0028] The glue scraper assembly 150 corresponds to the glue tray 140 and is used to scrape the glue in the glue tray 140. In practical applications, the blade holder 152 is slidably connected to the mounting base 120, allowing the glue scraper 154 to adjust its position as the blade holder 152 moves. The glue scraper 154 is connected to the blade holder 152 and acts directly on the glue to scrape it flat. The elastic element 156 and the height adjustment module 158 are connected between the blade holder 152 and the mounting base 120. The height adjustment module 158 includes an adjusting nut 1582 on the mounting base 120 and a screw 1584 threadedly connected to the adjusting nut 1582. The elastic element 156 keeps the top of the screw 1584 and the bottom of the blade holder 152 in a supporting state. When the screw 1584 is rotated, due to the threaded engagement between the screw 1584 and the adjusting nut 1582, the screw 1584 will move up and down, thereby pushing the cutter holder 152 and moving the scraper blade 154 away from the glue tray 140, or pulling the cutter holder 152 down under the action of the elastic element 156, moving the scraper blade 154 closer to the glue tray 140. The movement accuracy of the cutter holder 152 depends on the pitch of the threads on the screw 1584, and the pitch can be flexibly set according to the required accuracy.

[0029] It should be noted that only one rotating component 130 can be provided. In this case, one glue tray 140 and one glue scraper component 150 are also provided. The thickness of the glue in the glue tray 140 is ensured through the cooperation of the rotating component 130, the glue tray 140, and the glue scraper component 150. Alternatively, two or three rotating components 130 can be provided. In this case, each rotating component 130 corresponds to one glue tray 140, and each glue tray 140 corresponds to one glue scraper component 150, to meet the usage requirements of different working conditions.

[0030] The glue storage device 100 for applying glue provided in this embodiment of the application, through the transmission connection between the drive motor 132 mounted on the bracket 110 and the rotating base 134, causes the glue tray 140 connected to the rotating base 134 to rotate synchronously when the rotating base 134 rotates relative to the mounting base 120. In this way, the glue loaded in the glue tray 140 and the glue scraper 154 move relative to each other, and the glue scraper 154 smooths the glue, ensuring the stability of the glue amount applied during application. Furthermore, when it is necessary to adjust the thickness of the smoothed glue, rotating the screw 1584 adjusts the distance between the glue scraper 154 and the glue tray 140, thereby achieving flexible adjustment of the glue layer thickness. Simultaneously, the elastic element 156 holds the top of the screw 1584 against the bottom of the blade holder 152, which can compensate for errors generated during processing and installation to a certain extent, reducing the requirements for processing and positioning accuracy, and thus reducing the difficulty of operation. Furthermore, the screw 1584 is located between the tool holder 152 and the mounting base 120, and does not protrude above the glue tray 140, thus avoiding interference with normal glue application. Through the cooperation between the glue scraper assembly 150 and the height adjustment module 158, the thickness of the glue layer inside the glue tray 140 can be adjusted during glue application, and the height can be adjusted simply by rotating the screw 1584, which helps to reduce the difficulty of precision control during assembly and adjustment.

[0031] like Figure 2 and Figure 3 As shown, the blade holder 152 includes a first connecting segment 1522 and a second connecting segment 1524 that are connected to each other, and the included angle between the first connecting segment 1522 and the second connecting segment 1524 is a right angle. The glue scraping assembly 150 also includes a slide rail 151 disposed on the mounting base 120, and a slider 153 that is slidably connected to the slide rail 151. The first connecting segment 1522 is fixedly connected to the slider 153, and the second connecting segment 1524 is fixedly connected to the glue scraper 154.

[0032] Specifically, the cooperation between the slide rail 151 and the slider 153 provides precise guidance for the sliding of the blade holder 152, making the movement of the scraper blade 154 more stable and smooth, improving the accuracy of the cooperation between the scraper blade 154 and the glue tray 140, and further reducing the difficulty of operation. At the same time, the right-angle structure of the blade holder 152 optimizes the installation position and angle of the scraper blade 154, allowing the scraper blade 154 to fit more closely to the surface of the glue tray 140, improving the scraping effect, ensuring the flatness of the glue layer, and facilitating the stability of the glue application. In addition, the elastic element 156 can be a tension spring or an elastic rope, with one end of the elastic element 156 connected to the first connecting section 1522 and the other end connected to the mounting base 120 to provide the required elastic force.

[0033] like Figure 3As shown, a notch 1524a is provided on the second connecting section 1524, the end of the screw 1584 corresponds to the notch 1524a, and the diameter of the screw 1584 is greater than the width of the notch 1524a. A retaining groove is provided at the end of the screw 1584, and the width of the retaining groove is less than the width of the notch 1524a.

[0034] Specifically, by aligning the end of the screw 1584 with the notch 1524a, and providing a retaining groove at the end of the screw 1584, a tool can be used to hold the screw 1584 within the retaining groove for rotation. In practical applications, the retaining groove can be an internal hexagonal groove, and an internal hexagonal wrench can be used to rotate the screw 1584. The width of the retaining groove is smaller than the width of the notch 1524a to facilitate the engagement between the tool and the screw 1584. The diameter of the screw 1584 is larger than the width of the notch 1524a to ensure stable engagement between the screw 1584 and the second connecting section 1524. Alternatively, cutting portions can be provided on opposite sides of the outer circumference of the screw 1584, and a nut wrench can be used to engage with the cutting portions to achieve rotation of the screw 1584.

[0035] like Figure 3 and Figure 4 As shown, the glue tray 140 is provided with an annular groove 142. The glue scraper 154 includes a connecting part 1542 and a scraping part 1544 connected to each other. The scraping part 1544 is engaged in the annular groove 142. The scraping part 1544 includes a scraping plate 1544a, guide plates 1544b provided on both sides of the scraping plate 1544a, and a top plate 1544c connected to the scraping plate 1544a and the guide plates 1544b respectively. The scraping part 1544 is connected to the connecting part 1542 through the top plate 1544c. A glue storage groove 1546 is formed between the top plate 1544c, the scraping plate 1544a and the guide plates 1544b, and the depth of the glue storage groove 1546 near the scraping plate 1544a is less than the depth of the glue storage groove 1546 away from the scraping plate 1544a.

[0036] Specifically, the annular groove 142 provides positioning and guidance for the scraper 1544, and ensures that the adhesive accumulates within the annular groove 142, reducing the contact area between the adhesive and air to extend the adhesive's usability and facilitating its cooperation with the scraper blade 154. The scraper plate 1544a is used to smooth the adhesive within the annular groove 142, and the guide plate 1544b has a certain curvature to facilitate its fit with the inner wall of the annular groove 142, ensuring smooth rotation between the adhesive tray 140 and the scraper blade 154. The adhesive storage tank 1546 is designed to store adhesive during the scraping process, preventing uneven scraping due to insufficient adhesive. In addition, the depth of the glue storage tank 1546 near the scraper 1544a is less than the depth of the glue storage tank 1546 away from the scraper 1544a. This difference in depth design of the glue storage tank 1546 helps the glue to accumulate at the scraper 1544a under its own weight and the combined action of the scraper 1544a, ensuring that there is always enough glue at the scraper 1544a, improving the scraping effect and making the glue layer smoother.

[0037] like Figure 3 As shown, the glue storage device 100 for applying glue also includes a light-shielding assembly 160. The light-shielding assembly 160 includes a support arm 162 rotatably connected to the mounting base 120 and a light-shielding plate 164 connected to the support arm 162. The mounting base 120 is also provided with a limiting member 166, which is used to limit the support arm 162 so that when the support arm 162 abuts against the limiting member 166, the light-shielding plate 164 is located above the glue tray 140.

[0038] Specifically, the main function of the light-shielding plate 164 is to block light from shining onto the adhesive in the glue tray 140, preventing the adhesive from changing its properties due to light exposure. For example, when using UV adhesive, it can delay the curing of the adhesive. The rotatable connection of the support arm 162 allows the light-shielding plate 164 to be opened or closed as needed, such as opening when adding adhesive and closing during the adhesive application process. The limiting member 166 ensures that the light-shielding plate 164 is accurately positioned above the glue tray 140 during operation.

[0039] Please continue to refer to this. Figure 3 The support arm 162 includes a first arm 1622 and a second arm 1624 connected at right angles. The first arm 1622 is rotatably connected to the mounting base 120, and the second arm 1624 is connected to the light shield 164. The limiting member 166 is a bolt and is threadedly connected to the mounting base 120. The light shield 164 is provided with a clearance opening 1642, which is used to avoid the glue scraper 154 and the glue stick used to pick up glue.

[0040] Specifically, the bolt, acting as a limiting member 166, can be rotated to adjust its height, thereby adjusting the position of the light-shielding plate 164. In practical applications, simply adjusting the limiting member 166 to a suitable height, with the first arm 1622 rotatably connected to the mounting base 120 until the second arm 1624 abuts against the top of the limiting member 166, ensures the stability of the relative positional relationship between the light-shielding plate 164 and the adhesive tray 140. Furthermore, the clearance opening 1642 prevents interference between the light-shielding plate 164 and the adhesive scraper 154 and the adhesive stick, ensuring the normal operation of all components.

[0041] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the glue storage device 100 for applying glue also includes a cleaning component 170 and a cleaning tape winding component 180. The cleaning component 170 is used to clean the glue stick. The cleaning component 170 includes a gripper cylinder 172 mounted on the bracket 110, and a first chuck 174 and a second chuck 176 connected to the gripper of the gripper cylinder 172. The cleaning tape winding component 180 is used to make the cleaning tape 181 pass through the first chuck 174 and the second chuck 176 in sequence, so as to clean the glue stick by means of the cleaning tape 181.

[0042] Specifically, during the glue application process, excess glue may remain on the surface of the glue stick. If not cleaned promptly, this will affect the subsequent glue application amount and effect, leading to unstable product quality. The cleaning component 170 and the cleaning belt winding component 180 can clean the glue stick in a timely manner, removing residual glue from its surface and ensuring a consistent state of the glue stick each time it is applied, thus ensuring the stability of the glue application amount. The continuous movement of the cleaning belt 181 ensures the cleaning effect and avoids the problem of incomplete cleaning caused by repeated use of the cleaning belt 181. When cleaning the glue stick, the gripper cylinder 172 drives the first gripper 174 and the second gripper 176 to move, and the cleaning is performed by the cleaning belt 181 passing through the first gripper 174 and the second gripper 176 in sequence. This process automates the cleaning process, improves work efficiency, and reduces the difficulty and error of manual operation.

[0043] like Figure 2 and Figure 5As shown, the cleaning belt winding assembly 180 includes a first connecting shaft and a second connecting shaft connected to the bracket 110, as well as a motor 182 and a damper 184 mounted on the bracket 110. The motor 182 is connected to the first connecting shaft, and the damper 184 is connected to the second connecting shaft. The bracket 110 is also provided with a first guide roller 185, a second guide roller 186, and a third guide roller 187. The second connecting shaft is used to load the cleaning belt 181. The cleaning belt 181 passes through the first guide roller 185, the first clamp 174, the second guide roller 186, the second clamp 176, and the third guide roller 187 in sequence, and then winds onto the first connecting shaft. Foam 177 is respectively provided on the inner side of the first clamp 174 and the second clamp 176.

[0044] Specifically, the motor 182 provides power to the first connecting shaft, driving the cleaning belt 181 to wind; the damper 184 provides damping to the second connecting shaft, ensuring that the cleaning belt 181 maintains appropriate tension during winding; the first guide roller 185, the second guide roller 186, and the third guide roller 187 are used to guide the direction of the cleaning belt 181, so that the cleaning belt 181 can pass through the first clamp 174 and the second clamp 176 according to a predetermined path; the foam 177 can play an elastic buffering role for the adhesive stick, and when the first clamp 174 and the second clamp 176 approach and squeeze the adhesive stick, the cleaning belt 181 inside the foam 177 has a larger contact area when cleaning the adhesive stick, thus improving the cleaning effect.

[0045] like Figure 6 As shown, the first clamp 174 is provided with a first roller 178 at its end, and the second clamp 176 is provided with a second roller 179 at its end. The cleaning belt 181 engages with the first clamp 174 via the first roller 178 and with the second clamp 176 via the second roller 179. A gear 188 is also provided on the first connecting shaft, and a length detection sensor 189 corresponding to the gear 188 is provided on the bracket 110 for sensing the length of the cleaning belt 181 extended.

[0046] Specifically, the arrangement of the first roller 178 and the second roller 179 makes the cleaning belt 181 move more smoothly, reducing friction between the cleaning belt 181 and the first clamp 174 and the second clamp 176, and preventing it from breaking due to excessive resistance during the winding and retraction of the cleaning belt 181. In addition, the cooperation of the gear 188 and the length detection sensor 189 can monitor the length of the cleaning belt 181 in real time. When the cleaning belt 181 reaches a certain length, it can remind the user to replace it, ensuring cleaning effectiveness. The length detection sensor 189 can be a through-beam photoelectric switch. The change in light signal is achieved through the engagement of the teeth on the gear 188, thereby determining the winding length of the cleaning belt 181.

[0047] This application also provides a pick-and-place machine, including a three-dimensional moving component, a glue-dipping stick disposed on the three-dimensional moving component, and a glue storage device 100 for dipping glue as described in the foregoing embodiments, wherein the glue-dipping stick is capable of dipping glue into the glue tray 140 of the glue storage device 100. The three-dimensional moving component can be implemented by splicing together linear moving modules respectively arranged in three mutually perpendicular directions to drive the glue-dipping stick to move to a specific spatial position. This pick-and-place machine has the same structure and beneficial effects as the glue storage device 100 for dipping glue in the foregoing embodiments. The structure and beneficial effects of the glue storage device 100 for dipping glue have been described in detail in the foregoing embodiments and will not be repeated here.

[0048] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
