Description

Technical Field

[0001] This invention relates to the field of silicone jig production equipment technology, and in particular to an integrated device for automatic glue scraping and residual glue cleaning of silicone jigs. Background Technology

[0002] In the manufacturing process of silicone products, silicone jigs are often used to complete the casting and molding of AB glue. During the operation, AB glue needs to be poured into the groove of the jig plate, and then the AB glue inside the groove is scraped flat by a glue scraper to ensure that the glue is filled evenly, thereby ensuring the quality of the subsequent silicone product molding.

[0003] After the glue is scraped, the glue will overflow from the groove, forming residual glue on the upper surface of the jig plate and the sides of the plate. Currently, the residual glue is usually removed manually by wiping with a lint-free cloth or scraper. However, it is difficult to control the wiping force manually. When cleaning the residual glue, it is easy to pull up the glue that has been scraped flat inside the groove, causing the glue edge inside the groove to become rough and uneven, which directly affects the yield of finished products. At the same time, manual cleaning also has the problems of incomplete cleaning and poor cleaning consistency, resulting in large fluctuations in product quality during mass production.

[0004] Therefore, it is necessary to provide an integrated device for automatic glue scraping and residual glue cleaning of silicone jigs to solve the above-mentioned technical problems. Summary of the Invention

The limiting member is provided with a stop part, a clearance part, and a guide part connecting the two on the side opposite to the slide rod. The clearance part is recessed inward relative to the stop part along the length direction of the scraper towards the side away from the slide rod. A protrusion is provided at one end of the slide rod that passes through the connecting plate. During the process of the driving member driving the scraper to deflect around the fixed axis, the protrusion disengages from the stop part and slides towards the clearance part.

[0011] As a further aspect of the present invention: a connecting member is provided between the slide rod and the pin, the connecting member is fixedly connected to the connecting rod along the axial direction of the pin and rotates in cooperation with it along the circumferential direction of the pin, and the unwinding drum is axially fixedly connected to the slide rod.

[0020] like Figures 1-10 As shown, an integrated device for automatic scraping and residual adhesive cleaning of silicone jigs includes a scraper 6 for uniformly coating AB glue onto the groove 101 at the top of the jig plate 1 and a drive assembly for driving the scraper 6 to move horizontally; it also includes a drive component 18 for driving the scraper 6 to deflect around a fixed axis. It should be noted that the drive component 18 can move synchronously with the scraper 6 in the horizontal direction.

[0021] Reference Figure 7 As shown, during actual operation, vacuum-sealed AB glue is poured into the groove 101 at the top of the fixture plate 1. The drive assembly drives the scraper 6 to move slowly back and forth relative to the fixture plate 1. The tilt angle of the scraper 6 can be adjusted by the drive component 18, which helps to evenly fill the groove 101 with AB glue. Specifically, the scraper 6 can be adjusted to a near-vertical state and attached to the top of the fixture plate 1; or the scraper 6 can be adjusted to a tilted state and attached to the top of the fixture plate 1. When the scraper 6 moves to the edge of the fixture plate 1 along one side, the drive component 18 drives the scraper 6 to deflect away from the fixture plate 1 around the fixed axis, so that the scraper 6 is no longer in contact with the top of the fixture plate 1. Then, the drive component moves the scraper 6 away from the fixture plate 1 and drives the scraper 6 to deflect in the opposite direction around the fixed axis through the drive component 18, so that the other side of the scraper 6 can be reattached to the top of the fixture plate 1. At this time, the drive component can drive the scraper 6 to move in the horizontal direction to perform the scraping operation again. Repeating the above actions 4-5 times can evenly fill the AB glue into the groove 101.

[0022] During the process of the scraper 6 reciprocating to fill the groove 101 with AB glue, some glue will inevitably flow to the perimeter of the groove 101 and the side of the fixture plate 1. Therefore, after the AB glue filling is completed, it is generally necessary to clean the residual glue around the groove 101 and the side of the fixture plate 1. Based on this, this solution also provides a cleaning component on one side of the scraper 6 for removing residual glue, combined with... Figures 3-7 As shown, the cleaning assembly includes a roll unwinding drum 17, a roller 10, and a lint-free cloth 5. The lint-free cloth 5 is wound around the outside of the roll unwinding drum 17, and one free end of the lint-free cloth 5 is fixedly connected to the roller 10.

[0023] When the drive component 18 drives the scraper 6 to deflect around a fixed axis at a certain angle, the scraper 6 disengages from the top of the fixture plate 1, while the roll 10 abuts against the area on the top of the fixture plate 1 located outside the groove 101. During the horizontal movement of the scraper 6 driven by the drive component, the roll 10 rotates due to the friction between itself and the top surface of the fixture plate 1, thereby winding up the lint-free cloth 5. The lint-free cloth 5 can then be used to clean the residual adhesive around the groove 101. Traditional cleaning methods often involve scraping with the scraper 6 or wiping manually. During the residual adhesive cleaning process, the adhesive inside the groove 101 is easily pulled and disturbed, causing unevenness, burrs, and other defects at the edges of the adhesive-filled groove 101. In this solution, as the lint-free cloth 5 is rolled up to the outside of the roller 10, it is pressed between the roller 10 and the top surface of the fixture plate 1, which can absorb residual adhesive around the groove 101. Furthermore, the roller 10 presses the lint-free cloth 5 tightly around the groove 101, enabling stress separation between the residual adhesive in contact with the lint-free cloth 5 and the adhesive inside the groove 101. Therefore, the cleaning operation will not disturb or damage the adhesive inside the groove 101. Subsequently, the roller 10 continues to rotate and roll up the lint-free cloth 5, winding and storing the lint-free cloth 5 that was originally in contact with the top surface of the fixture plate 1 onto the roller 10. The residual adhesive attached to the periphery of the groove 101 is then peeled off by the lint-free cloth 5, thus completing the residual adhesive cleaning.

[0024] Combination Figures 1-4 As shown, the upper part of the scraper 6 is connected and fixed to a scraper holder 601 by bolt-like fasteners. Connecting plates 602 are fixed to both sides of the top of the scraper holder 601. A U-shaped connecting frame 9 is provided above the scraper holder 601. A central shaft 20 is fixedly mounted on the connecting plate 602 along the length of the scraper 6. The central shaft 20 passes through the side of the connecting frame 9 and forms a rotating pair with the connecting frame 9. Relying on this rotating fit structure, the scraper 6 can deflect around the axis of the central shaft 20 as the center of rotation, thereby switching between station one for scraping adhesive and station two for cleaning residual adhesive.

[0025] A U-shaped tie rod 19 is fixed between the two sets of connecting plates 602, as shown in the reference. Figure 4As shown, the driving component 18 is configured as an electric cylinder or a pneumatic cylinder, etc. The tail end of the driving component 18 is hinged to the connecting frame 9, and the telescopic end of the driving component 18 is hinged to the pull rod 19. Both sets of hinge axes are arranged parallel to the axis of the central axis 20. In this structure, the telescopic movement of the driving component 18 can drive the connecting plate 602 and the scraper 6 to deflect around the axis of the central axis 20, so that the scraper 6 can switch between the first workstation and the second workstation.

[0026] The drive assembly includes a lead screw 8 and a guide shaft 7. A protrusion 901 that mates with the lead screw 8 and a guide block that mates with the guide shaft 7 are fixed on the connecting frame 9. Specifically, the lead screw 8 passes through the protrusion 901 and is threadedly connected to it, while the guide shaft 7 passes through the guide block, and the two form a sliding pair, which facilitates guiding the movement of the connecting frame 9. In this structure, the scraper 6 can be driven to reciprocate horizontally by rotating the lead screw 8 in both directions, thereby facilitating the filling of AB glue into the groove 101 or the cleaning of residual glue around the groove 101.

[0027] The device is also equipped with brackets on both sides. Both ends of the lead screw 8 and the guide rod are rotatably connected to the brackets, and a motor is installed on the bracket. The output end of the motor is connected to the end of the lead screw 8 that passes through the bracket.

[0028] The spool 10 is rotatably mounted relative to the scraper holder 601 via a connecting rod 11. See Figures 3-6 for details. A base 15 is fixedly mounted on the top of the scraper holder 601. A pin 14 is fixedly mounted on the base 15 along the length of the scraper 6. The pin 14 passes through a pre-drilled through hole in the connecting rod 11, allowing the connecting rod 11 to rotate relative to the pin 14 around its axis and also to move horizontally relative to the pin 14 along its axis. One end of the spool 10 passes through the connecting rod 11 and is rotatably connected to it via a one-way bearing. This configuration ensures that the spool 10 can only rotate in one direction, preventing the cleanroom cloth 5 from becoming loose. The connecting rod 11 is also elastically connected to the pin 14 along its circumference.

[0029] When the drive unit 18 drives the scraper 6 to deflect around the fixed axis, causing the lint-free cloth 5 wound on the outside of the roll 10 to adhere to the area around the groove 101, the elastic pre-tightening force provided by the connecting rod 11 can press the lint-free cloth 5 on the outside of the roll 10 to the periphery of the groove 101, thereby improving the adsorption and cleaning effect of the lint-free cloth 5 on the residual adhesive around the groove 101.

[0030] The unwinding drum 17 is arranged on one side of the connecting plate 602, and a rotatable connection is formed between the unwinding drum 17 and the connecting plate 602. Specifically, a slide rod 21 is mounted on the connecting rod 11 along the length direction of the scraper 6, and the unwinding drum 17 is sleeved on the outer periphery of the slide rod 21 and forms a rotatable engagement with the slide rod 21. With the above structure, when the cleanroom cloth 5 on the outside of the roll 10 is in contact with the top surface of the fixture plate 1, and the roll 10 moves relative to the fixture plate 1 as a follower mechanism, the rotating roll 10 performs a winding action on the cleanroom cloth 5, and simultaneously drives the unwinding drum 17 to rotate around its own axis, thus completing the unwinding supply of the cleanroom cloth 5.

[0031] In one embodiment, the slide rod 21 is fixedly connected to the connecting plate 602 at least along the circumferential direction of the slide rod 21. Specifically, the inner wall of the circular hole through which the slide rod 21 passes on the connecting plate 602 can protrude outward along the diameter direction to form a protrusion structure, and the outer circular surface of the slide rod 21 is provided with a groove along its axial direction that slides and engages with the protrusion structure; or the part of the slide rod 21 that engages with the connecting plate 602 is set as a prism shape, thereby restricting the rotation of the slide rod 21 relative to the connecting plate 602; furthermore, retaining rings 2103 are provided on the outer side of the connecting rod 11 and at both ends of the unwinding drum 17, wherein the retaining ring 2103 near the connecting plate 602 is fixedly connected to the slide rod 21, while the other retaining ring 2103 is detachably connected to the slide rod 21. For example, combined with Figure 6 As shown, after the unwinding drum 17 is fitted onto the outside of the slide rod 21, the retaining ring 2103 on the side away from the connecting plate 602 is fitted onto the outside of the slide rod 21 and abuts against the end of the unwinding drum 17. By adjusting the pressure between the rubber pad at the end of the retaining ring 2103 and the end of the unwinding drum 17, the resistance to the rotation of the unwinding drum 17 can be adjusted, thereby preventing the unwinding drum 17 from rotating spontaneously when the scraper 6 is in position one, which would cause the cleanroom cloth 5 to loosen. In this embodiment, the retaining ring 2103 on the side away from the connecting plate 602 can be threadedly connected to the slide rod 21 or fixedly connected to the slide rod 21 by a radially arranged screw. That is, the screw is set radially through the retaining ring 2103 and threadedly connected to it, and one end of the screw abuts against the outer wall of the slide rod 21.

[0032] In actual use, to clean residual adhesive on the side of the jig plate 1, this solution also includes a side scraper 4, which is vertically arranged and located on the outer side of the jig plate 1. Combined with... Figure 3 , Figure 6As shown, a guide seat 12 that cooperates with the side scraper 4 is fixed on the connecting rod 11. The side scraper 4 is elastically engaged with the guide seat 12 in the vertical direction, and the top arc portion of the side scraper 4 abuts against the outer side of the lint-free cloth 5 sleeved on the outer side of the roll 10. Specifically, a limiting block 401 is fixed on one side of the blade holder mounted on the side scraper 4. The limiting block 401 has a T-shaped structure and passes through a pre-set through groove on the guide seat 12. The two sides of the limiting block 401 slide against the side of the guide seat 12 away from the side scraper 4, thereby locking the guide seat 12 and the side scraper 4 along the axial direction of the roll 10. Further, an elastic element 13, such as a spring, is connected between the bottom end of the through groove and the limiting block 401, so that the two are elastically connected along the diameter direction of the roll 10.

[0033] In this embodiment, the connecting rod 11 is connected to the unwinding drum 17 via the connecting member 16. Specifically, the connecting rod 11 and the connecting member 16 are rotatably connected along the circumferential direction of the pin 14 and fixedly connected along the axial direction of the pin 14, so that the unwinding drum 17 and the winding shaft 10 can move synchronously along the axial direction of the pin 14. In this embodiment, the sliding rod 21 is slidably connected to the connecting plate 602, thereby adjusting the distance between the side scraper 4 and the fixture plate 1, so that when the scraper 6 is in the second working position, the side scraper 4 can be in close contact with the side of the fixture plate 1, thereby cleaning the residual glue on the side.

[0034] The bottom end of the connecting frame 9 is fixed with a limiting member 22. The limiting member 22 is L-shaped and arranged along the length of the scraper 6. The inner side of the vertical section of the limiting member 22 is provided with a stop part 2201, a clearance part 2203, and a guide part 2202 connecting the two. Specifically, the clearance part 2203 is recessed relative to the stop part 2201 along the length of the scraper 6 away from the slide rod 21, and the guide part 2202 is set as a slope or arc surface. One end of the slide rod 21 that passes through the connecting plate 602 is fixed with a stop member 2101, and the stop member 2101 is connected to the connecting plate 602 with a limiting spring, so that the slide rod 21 is elastically connected to the connecting plate 602 along the length of the scraper 6. The stop member 2101 protrudes outward along the length of the scraper 6 to form a protrusion 2102 that cooperates with the limiting member 22.

[0035] It is understood that the cooperation between the protrusion 2102 and the stop 2201 is in response to the first working position of the scraper 6. Under this condition, the protrusion 2102 abuts against the stop 2201, and the side scraper 4 is in a disengaged state from the side of the fixture plate 1. The dust-free cloth 5 on the outside of the roll 10 does not contact the periphery of the groove 101. The drive assembly drives the scraper 6 to reciprocate in the horizontal direction to complete the glue scraping operation. The cooperation between the protrusion 2102 and the avoidance part 2203 is in response to the second working position of the scraper 6. In this working condition, the protrusion 2102 is offset from the stop part 2201 and moves towards the avoidance part 2203 through the guide part 2202, so that the slide rod 21 moves towards the vertical section of the limiting member 22 under the elastic force of the limiting spring, and finally makes the side scraper 4 abut against the side of the fixture plate 1.

[0036] In summary, when the drive unit 18 drives the scraper 6 to deflect around the central axis 20 via the pull rod 19, the protrusion 2102 slides from the stop part 2201 to the avoidance part 2203, causing the slide rod 21 to slide horizontally under elastic force. During this process, the lint-free cloth 5 wound around the outside of the roll 10 will contact the top of the jig plate 1 to clean the residual adhesive around the groove 101, while the side scraper 4 abuts against the side of the jig plate 1, which is beneficial for cleaning the residual adhesive on the side of the jig plate 1. Compared with traditional scraper cleaning or manual cleaning, this device can clean the residual adhesive on the jig plate 1 from all directions, and will not disturb or damage the glue already filled in the groove 101 during the cleaning process.

[0037] Reference Figure 5 As shown, the connector 16 is at least circumferentially fixedly connected to the slide rod 21. In a specific embodiment, the slide rod 21 can pass through the connector 16 and be fixedly connected to it. A connector head 1102 is provided on the side of the connecting rod 11 near the connector 16. It should be noted that the connector head 1102 is sleeved on the outside of the pin 14 and is fixedly connected to the connecting rod 11. The connector 16 has a slot for installing the connector head 1102, and the inner end face of the slot has a connecting groove 1601 that mates with the end of the connector head 1102. Specifically, the cross-sections of the connecting groove 1601 and the connector head 1102 along their axial direction are both T-shaped structures. Through this structure, when the connector head 1102 is rotatably disposed inside the connecting groove 1601, the connector head 1102 and the connector 16 can be fixedly disposed along the axial direction of the pin 14. Furthermore, a torsion spring 1103 is sleeved on the outer side of the connector 1102. The two free ends of the torsion spring 1103 are connected to the connector 1102 and the connector 16, respectively, so that the connecting rod 11 and the connector 16 are elastically engaged in the circumference. With this structure, when the drive member 18 drives the scraper 6 to rotate around the central axis 20 and presses the clean cloth 5 on the outer side of the roll 10 against the top of the fixture plate 1, the connecting rod 11 can deflect around the pin 14 and compress the torsion spring 1103. Thus, the reaction force of the torsion spring 1103 can further press the roll 10 against the top of the fixture plate 1.

[0038] Reference Figure 6 , Figure 8As shown, a sleeve 1701 is coaxially provided at the end of the unwinding drum 17 away from the connecting plate 602, and the sleeve 1701 is fixedly connected to the unwinding drum 17. The retaining ring 2103 on the side away from the connecting plate 602 can abut against the outer end face of the sleeve 1701, thereby controlling the resistance when the unwinding drum 17 rotates relative to the slide rod 21. Further, multiple sets of slots 1702 are formed on the outer circular surface of the sleeve 1701 along its axial direction. The multiple sets of slots 1702 are distributed in a circumferential array. One end of the connecting rod 11 extends to the sleeve 1701, and the side of the connecting rod 11 near the sleeve 1701 is provided with a protruding tooth 1101 that cooperates with the slot 1702. With this structure, when the cleanroom cloth 5 on the outside of the roll 10 is pressed against the top of the fixture plate 1, causing the connecting rod 11 to deflect around the pin 14, the protruding tooth 1101 can disengage from the slot 1702, thereby allowing the unwinding drum 17 to rotate to release the cleanroom cloth 5. When the roll 10 is reset so that the scraper 6 is in position one, the connecting rod 11 is reset and the protruding tooth 1101 can be engaged in the slot 1702, thereby preventing the unwinding drum 17 from rotating and helping to prevent the cleanroom cloth 5 from becoming loose and affecting the next use.

[0039] Reference Figures 6-7 As shown, the connecting plate 602 is provided with an adjusting shaft 23, which is arranged along the length of the scraper 6 and is slidably connected to the connecting plate 602. The sliding direction can be perpendicular to the cleanroom cloth 5 between the roll 10 and the unroll drum 17. Specifically, the connecting plate 602 has a guide groove that slides with the adjusting shaft 23. Two sets of sliders 25 are fixedly sleeved on the adjusting shaft 23, and the two sets of sliders 25 are respectively disposed on both sides of the connecting plate 602. The bottom of each slider 25 is provided with a limiting plate 24, which is fixed to the connecting plate 602. Figure 7 As can be seen, the limiting plate 24 has multiple limiting grooves on the side near the slider 25, and the bottom of the slider 25 is elastically connected to a wedge block 2501 via a spring along a direction perpendicular to the surface of the limiting plate 24. The cooperation between the inclined surface of the wedge block 2501 and the limiting groove allows the slider 25 to slide downward relative to the limiting plate 24. With this structure, when the cleanroom cloth 5 between the unwinding drum 17 and the winding shaft 10 becomes loose, the adjusting shaft 23 slides towards the cleanroom cloth 5 under its own weight and tightens the cleanroom cloth 5. Since the slider 25 only moves downward relative to the limiting plate 24, the rotation of the winding shaft 10 and the winding of the cleanroom cloth 5 will not cause the adjusting shaft 23 to move upward, which helps to further pull the cleanroom cloth 5 closer, so that the cleanroom cloth 5 on the outside of the winding shaft 10 can press against the top of the fixture plate 1.

[0040] Combination Figures 1-2As shown, the device also includes a base 2 and a fixing member 3 disposed on the top of the base 2. The fixing member 3 is used to fix the jig plate 1. In one embodiment, the worker can fix the jig plate 1 to the outer support using an external clamp. Of course, in another embodiment, the fixing member 3 can be provided with an air chamber inside, and the top of the fixing member 3 is provided with an air hole communicating with the air chamber. By using an external air pump to evacuate the air chamber, the jig plate 1 is attracted to the top of the fixing member 3 through negative pressure to fix the jig plate 1. In a further embodiment, the fixing member 3 can be rotatably connected relative to the base 2. For example, a servo motor is provided inside the base 2, and the output end of the servo motor is connected to the fixing member 3 to drive the fixing member 3 to rotate, which is beneficial for rotating the jig plate 1 and for thoroughly cleaning the residual adhesive around the groove 101. It is understood that during the rotation of the jig plate 1, the drive component needs to move the scraper 6 away from above the jig plate 1 to avoid interference between the two.

[0041] The above-disclosed examples are merely preferred embodiments of this application, intended to facilitate understanding and implementation by those skilled in the art. However, they cannot be used to limit the scope of this application. Therefore, equivalent variations made within the scope of this application are still within the scope of this application.
