Description

Technical Field

[0001] The present application relates to the technical field of electronic component production auxiliary mechanisms, and in particular to an RTV glue supply mechanism. Background Art

[0002] RTV glue is widely used in the packaging or bonding of electronic components and semiconductor materials as a bonding, sealing, insulating, moisture-proof and shock-absorbing material. It is mainly packaged in a rubber tube, which is hollow inside and has an opening at one end. A piston is slidably arranged inside the rubber tube, so that a cavity for holding the glue liquid is formed inside the rubber tube. A glue outlet is provided on the end face of the rubber tube away from its own opening, and the glue outlet is blocked with a sealing film. When in use, the sealing film is punctured, and then the piston is moved to discharge the glue liquid.

[0003] When using RTV glue, the sealing film is penetrated or torn off, and then the opening of the rubber cartridge is connected to the one-way valve. In order to facilitate the connection between the rubber cartridge and the one-way valve, a circular sleeve is usually set at the rubber outlet of the rubber cartridge. After the one-way valve is connected to the sleeve, the staff can move the piston to make the glue flow and flow out from one side of the one-way valve to complete the glue supply.

[0004] During the replacement of the rubber cartridge, the sealing film needs to be penetrated or torn off first, so it is easy for the rubber to leak during the replacement process, which not only causes waste but also leads to dirt on the site. Utility Model Content

[0005] In order to reduce waste and the occurrence of on-site dirt during the glue replacement process, the present application provides an RTV glue supply mechanism.

[0008] By adopting the above technical solution, when replacing the rubber cartridge, the tip of the penetrating member is directed toward the sealing film on the rubber cartridge, and then moved toward the rubber cartridge. During the movement, the tip pierces the sealing film and is inserted into the inside of the rubber cartridge. At this time, the inside of the rubber cartridge is connected to the glue outlet member, and the glue can flow out from the glue outlet member. This reduces the phenomenon of prematurely piercing the sealing film when replacing the rubber cartridge, which causes the glue to flow out and cause waste or dirt on the site.

[0009] Optionally, the penetrating member can be inserted into a sleeve on the rubber sleeve and fit with the inner wall of the sleeve.

[0010] By adopting the above technical solution, the penetrating piece is inserted into the casing and fits with the inner wall of the casing, which improves the stability of the penetrating piece after being connected to the rubber tube, and improves the sealing between the side wall of the penetrating piece and the rubber tube, reducing the leakage of the rubber liquid between the rubber tube and the penetrating piece.

[0016] By adopting the above technical solution, the limiting rod is inserted into the limiting groove to limit the relative position between the connecting member and the mounting tube, thereby preventing the connecting member from being separated from the mounting tube and realizing the connection between the connecting member and the mounting tube.

[0017] Optionally, the inner side wall of the connecting piece is cylindrical, and the limiting groove includes a horizontal portion and a vertical portion, the horizontal portion extends circumferentially along the inner side wall of the connecting piece, and the vertical portion extends radially along the inner side wall of the connecting piece, and an opening is formed on the side of the connecting piece away from the glue outlet piece, and the horizontal portion and the vertical portion are connected to each other.

[0018] By adopting the above technical solution, when installing the connecting piece, the opening of the vertical part is aligned with the limiting rod, and then the connecting piece is moved to make the limiting rod slide to a position in the vertical part corresponding to the horizontal part, and then the connecting piece is rotated to make the limiting rod move into the horizontal part to prevent the connecting piece from being separated from the installation tube. When removing the connecting piece, the above steps are performed in reverse.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The embodiment of the present application discloses an RTV glue supply mechanism.

[0035] Reference Figure 1 and Figure 2 A RTV glue supply mechanism includes a fixed component 1, a glue outlet 2 and a piercing component 3. The fixed component 1 is used to fix the glue cylinder 8 so that it is connected to the production equipment of electronic components. The glue outlet 2 is detachably connected to one side of the fixed component 1, and is used to connect with the glue outlet of the glue cylinder 8 (the glue outlet 2 is a one-way valve in this embodiment), and the glue in the glue cylinder 8 can flow out from the side of the glue outlet 2 away from the fixed component 1. The piercing component 3 is installed on the side of the glue outlet 2 close to the fixed component 1, and is used to penetrate the sealing film on the glue cylinder 8. When the glue supply mechanism is used, the glue cylinder 8 is installed on the fixed component 1, and then the glue outlet 2 is installed on the fixed component 1, and the glue outlet 2 is installed. The piercing component 3 pierces the sealing film to connect the glue outlet 2 with the inside of the glue cylinder 8, thereby reducing the spillage of glue during the replacement of the glue cylinder 8, resulting in waste or dirt on the site.

[0036] Reference Figure 2 and Figure 3The piercing assembly 3 includes a penetrating member 31, which is a cylindrical structure. A conical surface 312 is provided on the side of the penetrating member 31 close to the mounting cylinder 11. The conical surface 312 is inclined along the length direction of the penetrating member 31 from the side close to the glue outlet 2 to the side away from the glue outlet 2 in the direction close to the axis of the penetrating member 31, forming a conical tip. A connecting groove 311 is provided on the side of the penetrating member 31 close to the glue outlet 2, and the glue outlet 2 is connected to the connecting groove 311. A glue inlet hole 313 is provided on the conical surface 312, and the glue inlet hole 313 is connected to the connecting groove 311. When the piercing assembly 3 is moved in the direction close to the mounting cylinder 11, the tip of the penetrating member 31 pierces the sealing film and is inserted into the inside of the rubber cylinder 8. At this time, the inside of the rubber cylinder 8 is connected to the connecting groove 311, so that the glue inside the rubber cylinder 8 can flow into the glue outlet 2. In order to improve the efficiency of the glue entering the connecting groove 311, a plurality of glue inlet holes 313 are evenly spaced around the circumference of the penetrating member 31, and four are arranged in this embodiment.

[0037] Reference Figure 2 and Figure 3 The puncture assembly 3 also includes a rubber ring 32, which is sleeved on the penetration member 31. An annular groove is provided on the penetration member 31 at a position corresponding to the rubber ring 32, and the rubber ring 32 is partially immersed in the annular groove. When the tip of the penetration member 31 penetrates into the rubber tube 8, the side wall of the penetration member 31 fits with the inner wall of the sleeve. At the same time, the rubber ring 32 is squeezed to improve the sealing between the penetration member 31 and the sleeve, and reduce the occurrence of glue leakage. In order to further improve the sealing between the penetration member 31 and the sleeve, a plurality of rubber rings 32 can be evenly spaced along the length direction of the penetration member 31, and three are set in this embodiment.

[0038] Reference Figure 2 and Figure 4 The fixing assembly 1 includes a mounting tube 11 and a mounting seat 13. The mounting tube 11 is a cylindrical tube structure. A through hole for placing the rubber tube 8 is formed inside the mounting tube 11. The mounting seat 13 is used to connect with the electronic component production equipment. The mounting seat 13 is provided with a slot 131. One end of the mounting tube 11 is inserted into the slot 131 to achieve the connection between the mounting tube 11 and the mounting seat 13, and at the same time, the mounting tube 11 is blocked. The rubber tube 8 can be inserted into the mounting tube 11 from the opening of the mounting tube 11 away from the mounting seat 13.

[0039] Reference Figure 2 and Figure 5 The fixing assembly 1 further includes a connecting member 14 and a limiting rod 15, and the connecting member 14 is a ring structure. Figure 3, the end of the penetration member 31 close to the glue outlet member 2 is sleeved and welded with a mounting plate 33. One end of the connecting member 14 is fixedly connected to the mounting plate 33 by a screw. The end of the connecting member 14 away from the mounting plate 33 is sleeved on the mounting cylinder 11. One end of the limiting rod 15 is welded to the side wall of the mounting cylinder 11, and the other end extends in the radial direction of the mounting cylinder 11 away from the mounting cylinder 11. A limiting groove 16 is provided on the inner side wall of the connecting member 14, and the end of the limiting rod 15 away from the mounting cylinder 11 is inserted into the limiting groove 16, so as to prevent the connecting member 14 from being separated from the mounting cylinder 11, and improve the stability of the penetration member 31 after being inserted into the inside of the glue cylinder 8.

[0040] Reference Figure 5 The limiting groove 16 includes a horizontal portion 161 and a vertical portion 162. The horizontal portion 161 extends along the circumferential direction of the connecting member 14, and the vertical portion 162 extends along the axial direction of the connecting member 14, and forms an opening on the side of the connecting member 14 away from the glue outlet member 2. The horizontal portion 161 and the vertical portion 162 are connected to each other. When the connecting member 14 is connected to the mounting tube 11, the connecting member 14 is moved toward the mounting tube 11, and the limiting rod 15 can slide from the opening of the vertical portion 162 to the inside of the vertical portion 162. When the limiting rod 15 corresponds to the horizontal portion 161, the connecting member 14 is rotated to move the limiting rod 15 to the inside of the horizontal portion 161 to limit the connecting member 14.

[0041] Reference Figure 2 and Figure 4 An air-filling cavity 17 is formed between the mounting seat 13, the rubber cylinder 8 and the piston 81 inside the rubber cylinder 8, and an air-filling hole 12 is provided on the mounting seat 13. Air is introduced into the air-filling cavity 17 through the air-filling hole 12, so that the pressure inside the air-filling cavity 17 can be increased, thereby pushing the piston 81 to move and squeeze the glue liquid out of the glue outlet.

[0042] Reference Figure 2 and Figure 4A plugging assembly 4 is provided on the side of the mounting seat 13 close to the mounting cylinder 11. The plugging assembly 4 includes a plugging member 41 and an elastic member 42. The plugging member 41 is a circular ring structure. The plugging member 41 is slidably connected to the inside of the slot 131 along the length direction of the mounting cylinder 11. The plugging member 41 is located on the side of the mounting cylinder 11 away from the glue outlet 2. The outer wall of the plugging member 41 is in contact with the side wall of the slot 131, and an elastic sealing ring is pasted on the outer wall of the plugging member 41. The inflation hole 12 is connected to the inside of the plugging member 41, and the elastic sealing ring can prevent the gas from flowing out of the gap between the plugging member 41 and the mounting seat 13, and then from flowing out of the gap between the mounting cylinder 11 and the glue cylinder 8. The elastic member 42 is installed on the side of the plugging member 41 away from the glue outlet 2, and is used to keep the plugging member 41 moving in the direction close to the glue outlet 2. In this embodiment, the elastic member 42 is a spring, one end of which is welded to the mounting seat 13, and the other end is welded to the plugging member 41. Under the action of the elastic member 42 , the blocking member 41 can be pressed against the opening of the rubber tube 8 close to the piston 81 , thereby preventing the gas from flowing out from between the blocking member 41 and the side wall of the rubber tube 8 .

[0043] Reference Figure 5 A guide surface 5 is provided on the side of the horizontal portion 161 away from the glue outlet member 2, and the guide surface 5 is inclined along the length direction of the horizontal portion 161 from the direction away from the vertical portion 162 to the direction close to the glue outlet member 2, so that when the connecting member 14 is rotated, the guide surface 5 can drive the connecting member 14 to move in the direction close to the mounting cylinder 11, and at the same time further compress the elastic member 42.

[0044] Reference Figure 5 A blocking groove 6 is provided on the guide surface 5. During the rotation of the connecting member 14, when the limiting rod 15 corresponds to the blocking groove 6, the side of the limiting rod 15 is placed in the blocking groove 6, thereby preventing the connecting member 14 from rotating. Under the action of the elastic member 42, the limiting rod 15 can be stably in the blocking groove 6, thereby further improving the stability of the connecting member 14 after being connected to the mounting tube 11.

[0045] Reference Figure 2 and Figure 4 The mounting seat 13 is also provided with a booster assembly 7, which includes a pressurizing cylinder 71 and a pressurizing flange 72. The pressurizing cylinder 71 is fixedly connected to the mounting seat 13 by screws, and the piston rod of the pressurizing cylinder 71 extends through the mounting seat 13 to the air charging chamber 17, and the pressurizing flange 72 is fixedly connected to the end of the piston rod by screws. During the production process of electronic components, the pressurizing cylinder 71 is started to assist in pushing the piston movement in the rubber cylinder 8, thereby improving the stability of the movement of the piston 81.

[0046] Reference Figure 2 and Figure 4Two sensors are arranged on the cylinder barrel of the pressurizing cylinder 71 at intervals along the length direction of the cylinder barrel, which are used to detect the position of the piston 81 inside the pressurizing cylinder 71, so as to determine the remaining amount of glue in the rubber cylinder 8, which is convenient for the staff to prepare the rubber cylinder 8 in advance for replacement.

[0047] The implementation principle of an RTV glue supply mechanism of the embodiment of the present application is as follows: when replacing the rubber cylinder 8, remove the connecting piece 14, and then insert the rubber cylinder 8 into the installation cylinder 11. Then, the connecting piece 14 is sleeved on the rubber cylinder 8 and moves in the direction close to the installation cylinder 11. During this process, the penetrating piece 31 can penetrate the sealing film, so that the tip of the penetrating piece 31 is inserted into the inside of the rubber cylinder 8, and the penetrating piece 31 is inserted into the sleeve on the rubber cylinder 8. The connecting piece 14 is rotated to insert the side of the limit rod 15 into the blocking groove 6, and the replacement of the rubber cylinder 8 is completed. Since there is no need to penetrate the sealing film in advance, the phenomenon of waste caused by leakage of glue and dirt on the site can be reduced.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
