Description

Technical Field

[0001] This utility model relates to the field of glue dispensing technology, and in particular to a glue delivery device with adjustable needle position. Background Technology

[0002] In existing technologies, when applying resin adhesive to a product surface for protection, the resin adhesive is typically poured into the cavity of an injection mold with an injection port. The product is then placed at the injection port of the injection mold so that the bottom surface of the product is in full contact with the injected resin adhesive. After the injected resin adhesive has cured, the product, along with the cured resin adhesive, can be removed from the injection mold. This completes the process of applying resin adhesive to the product surface for protection.

[0003] The current common practice is to manually fill the resin liquid into the mold cavity of the corresponding injection mold with the injection port, and place the product at the injection port of the injection mold to cover the resin liquid filled in the mold cavity.

[0004] In the course of his work, the inventor of this patent discovered that the aforementioned practices have certain defects and shortcomings.

[0005] Specifically, on the one hand, manually filling resin into the mold cavity of an injection mold with an injection port is very troublesome and laborious, and the amount of resin injected is also difficult to control. On the other hand, different injection molds have different heights, which means that the height of the upper injection port will also vary. This means that during the current operation, it is necessary to manually adjust the height of the injection tool and the injection needle installed at the bottom, making the operation even more troublesome. In addition, some injection molds may have irregular shapes, and their upper injection port may not be set straight upwards, that is, it may be set at an angle. This requires manual adjustment of the pointing angle of the injection needle installed at the bottom of the injection tool so that the injection needle can be inserted into the mold cavity of the injection mold with the injection port set at an appropriate angle. Thus, the operation is even more time-consuming and laborious.

[0006] In response, the inventor of this patent, drawing on work experience, deeply considered the problems encountered in his work, reviewed a large amount of scientific research data and literature, and gradually conceived and designed this application through a novelty search to solve the relevant technical problems. Utility Model Content

[0007] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the purpose of this invention is to provide a needle-position adjustable adhesive delivery device.

[0008] To achieve one of the above objectives, an adjustable needle position adhesive delivery device according to an embodiment of the present utility model includes a fixed plate, an up-and-down moving mechanism, an adhesive dispensing tank for dispensing adhesive, and an adhesive dispensing needle connected to the bottom of the dispensing tank for discharging adhesive.

[0009] The up-and-down moving mechanism is fixed to the front end face of the fixed plate; the glue injection barrel and the glue injection needle connected thereto are fixed to the up-and-down moving mechanism so that they can be driven to move up and down under the control of the up-and-down moving mechanism.

[0010] In addition, the needle position adjustable adhesive delivery device according to the above embodiments of the present invention may also have the following additional technical features:

[0011] According to one embodiment of the present invention, the up-and-down moving mechanism has a rotating plate that fits against the front end face of the fixed plate;

[0012] The lower end of the rotating plate is rotatably connected to the lower part of the fixed plate; when the rotating plate is rotated along the front end face of the fixed plate, the rotation angle of the up-down moving mechanism is adjustable, so that the lower end of the glue injection needle fixed on it can be oriented at an adjustable angle.

[0013] According to one embodiment of the present invention, it further includes a rotating shaft and a locking nut;

[0014] The fixing plate has a shaft hole in the lower middle part that penetrates its front and rear end faces, and an arc-shaped groove with the center point of the shaft hole as the center in the upper middle part.

[0015] The lower end of the rotating plate is rotatably connected to the lower part of the fixed plate through the rotating shaft that passes through the shaft hole in the front-back direction. The upper part of the rear end face of the rotating plate has a locking hole facing the arc groove. The locking nut is abutted against the rear end face of the fixed plate and passes through the arc groove and is screwed into the locking hole.

[0016] When the locking nut is loosened, the rotating plate can rotate around the rotating shaft and against the front end face of the fixed plate, so that the lower end of the glue injection needle can be oriented at an adjustable angle.

[0017] According to one embodiment of the present invention, the upper part of the front end face of the fixing plate is provided with an angle measuring scale line for indicating the angle of the lower end of the glue injection needle around the arc groove, and the angle measuring scale line is provided with an angle measuring value;

[0018] The upper part of the rotating plate is provided with an indicator arrow pointing to the angle scale line, and the central axis of the indicator arrow is parallel to the central axis of the glue injection needle in the front-back direction.

[0019] According to one embodiment of the present invention, the glue injection barrel has a glue inlet at the top and a glue guide head at the bottom, and the glue guide head is connected to the glue injection needle by insertion or thread.

[0020] According to one embodiment of the present invention, the up-and-down moving mechanism further includes a movable frame that can move up and down under its control, and the movable frame is provided with a first locking ring and a second locking ring from top to bottom;

[0021] The glue dispensing bucket is detachably secured to the first retaining ring, and the glue guide head is detachably secured to the second retaining ring.

[0022] According to one embodiment of the present invention, an upper stop limiting rod is provided on the upper part of the rotating plate to prevent the moving frame from moving upward to the upper limit position; a lower stop limiting rod is provided on the lower part of the rotating plate to prevent the moving frame from moving downward to the lower limit position.

[0023] The upper stop limit rod and the lower stop limit rod are vertically opposite each other; the movable frame is provided with a stop plate located between the upper stop limit rod and the lower stop limit rod.

[0024] According to one embodiment of the present invention, a horizontal plate is connected to the lower rear part of the fixing plate, and a fixing groove penetrating the upper and lower end faces of the horizontal plate is provided along the front-back direction.

[0025] According to one embodiment of the present invention, the left and right sides of the rear middle of the fixing plate are respectively provided with connecting ribs that connect to the horizontal plate.

[0026] According to one embodiment of the present invention, the up-and-down moving mechanism is a cylinder-driven linear module or a lead screw-driven linear module.

[0027] The beneficial effects of this utility model are:

[0028] Firstly, the adjustable needle position adhesive delivery device provided in this application, in specific implementation, uses the glue injection barrel and the glue injection needle connected to it to fill the resin adhesive into the mold cavity of the injection mold. It saves effort by eliminating the need for manual handling and also makes it easy to control the amount of resin adhesive injected. In specific implementation, a capacity scale can be set on the outer wall of the glue injection barrel from top to bottom. The amount of resin adhesive to be injected into the mold cavity of the injection mold each time can be controlled by observing the height of the resin adhesive level in the glue injection barrel and controlling the opening and closing of the switch valve installed at the bottom.

[0029] Secondly, for injection molds with a vertically upward-facing injection port, regardless of the height of the injection port, the injection barrel and the injection needle connected to it can be moved up and down to a suitable height under the control of the up-and-down moving mechanism. This ensures that the lower end of the injection needle can be inserted into the injection port of the injection mold at the appropriate height, preventing leakage of glue outside the injection port due to the lower end of the injection needle being too far away from it. As a result, this application is flexible, reliable, and highly adaptable to use.

[0030] Thirdly, for different injection molds, which may have irregular shapes, the upper injection port may not be set directly upwards. That is to say, it may be set at an angle so that it faces the upper left or upper right. In this case, the rotating plate can be rotated along the front end face of the fixed plate so that the up and down moving mechanism can be rotated to a suitable angle. This will drive the lower end of the injection needle fixed on it to face the appropriate angle, so that the installed injection needle can be inserted into the mold cavity of the injection mold with the injection port set at an appropriate angle. In this way, the operation of this application is more flexible and the adaptability is also stronger.

[0031] Fourthly, for the injection molds with different opening orientations, the direction of the injection needle can be adjusted to inject glue into the mold cavity of the injection mold with the different shape. When adjusting the direction of the injection needle, since this application is provided with the angle scale line, angle value and the indicator arrow, the angle of the injection needle can be accurately measured in a basically consistent manner, which is convenient for recording and archiving. This provides data reference for subsequent injection of glue into the mold cavity of the same irregular shape, so that the direction of the injection needle can be adjusted less effortfully, making this application more worry-free and labor-saving to use.

[0032] Fifthly, by setting the upper stop limit rod and the lower stop limit rod, it is easy to control the moving frame to move upward only to the upper limit position and not to move further upward, and it is also easy to control the moving frame to move downward only to the lower limit position and not to move further downward. This makes the vertical movement displacement of the moving frame controllable, so that the vertical movement range of the glue injection barrel and the glue injection needle connected to it is controllable and it is not easy to be damaged due to large vertical movement range.

[0033] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

"Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0069] The needle position adjustable adhesive delivery device 1000 of this utility model is described in detail below with reference to the accompanying drawings.

[0070] Reference Figures 1 to 3 As shown, the adjustable needle position adhesive delivery device 1000 provided according to the embodiment of this utility model includes a fixed plate 10, an up-down moving mechanism 20, an adhesive dispensing tank 30 with capacity scales on the outer wall from top to bottom for dispensing adhesive, and an adhesive dispensing needle 40 connected to the bottom of the adhesive dispensing tank 30 for dispensing adhesive.

[0071] The up-and-down moving mechanism 20 is fixed to the front end face of the fixed plate 10; the glue injection barrel 30 and the glue injection needle 40 connected thereto are fixed to the up-and-down moving mechanism 20 so that they can be driven to move up and down under the control of the up-and-down moving mechanism 20, and the bottom of the glue injection barrel 30 is provided with a switch valve.

[0072] Based on the above, it is clear that in specific implementation, this application is mainly used as a needle position adjustable adhesive delivery device 1000.

[0073] Specifically, when applying this application, a certain amount of resin is pre-filled in the injection barrel 30. For injection molds with the injection port facing straight upwards, regardless of the height of the injection port, the injection barrel 30 and the injection needle 40 connected to it can be moved up and down to a suitable height under the control of the up and down moving mechanism 20, so that the lower end of the injection needle 40 can just extend into the injection port of the injection mold of the appropriate height. In this way, this application can be used easily.

[0074] Clearly, the use of this application will have the following technical effects:

[0075] On the one hand, this application uses the glue injection bucket 30 and the glue injection needle 40 connected thereto to fill the resin liquid into the mold cavity of the injection mold. This not only saves effort by eliminating the need for manual handling, but also makes it easy to control the amount of resin liquid injected. In specific implementation, a capacity scale can be set on the outer wall of the glue injection bucket 30 from top to bottom. The amount of resin liquid to be injected into the mold cavity of the injection mold each time can be controlled by observing the height of the resin liquid level in the glue injection bucket 30 and controlling the opening and closing of the switch valve installed at the bottom of the bucket.

[0076] On the other hand, for injection molds with a straight upward injection port, regardless of the height of the injection port, the injection barrel 30 and the injection needle 40 connected to it can be moved up and down to a suitable height under the control of the up and down moving mechanism 20. This ensures that the lower end of the injection needle 40 can just extend into the injection port of the injection mold at the appropriate height, preventing leakage of glue outside the injection port of the injection mold due to the lower end of the injection needle 40 being too far away from the injection port. As a result, this application is flexible, reliable, and highly adaptable to use.

[0077] Furthermore, through the above-mentioned optimized design, the whole constituted by this application is highly practical and has a good effect in use.

[0078] Furthermore, in specific implementation, we will continue to refer to... Figures 1 to 3 As shown, according to one embodiment of the present invention, the up-down moving mechanism 20 has a rotating plate 201 that is in contact with the front end face of the fixed plate 10;

[0079] The lower end of the rotating plate 201 is rotatably connected to the lower part of the fixed plate 10. When the rotating plate 201 is rotated along the front end face of the fixed plate 10, the rotation angle of the up-down moving mechanism 20 is adjustable so that the lower end of the glue injection needle 40 fixed on it can be oriented at an adjustable angle.

[0080] It should be noted that different injection molds may have irregular shapes, and their upper injection ports may not be set straight upwards. That is, they may be set at an angle so that they face the upper left or upper right. In this case, the rotating plate 201 can be rotated along the front end face of the fixed plate 10 so that the up-down moving mechanism 20 can be rotated to a suitable angle. This will drive the lower end of the glue injection needle 40 fixed on it to face the appropriate angle, so that the installed glue injection needle can be inserted into the mold cavity of the injection mold with the injection port set at an angle upwards at a suitable angle. In this way, the operation of this application is more flexible and the adaptability is also greater.

[0081] Preferably, in this technical solution, it is still compared with Figures 1 to 3 As shown, according to one embodiment of the present invention, this application also includes a rotating shaft 50 and a locking nut 60;

[0082] The fixing plate 10 has a shaft hole 101 in the lower part that penetrates its front and rear end faces, and an arc-shaped groove 102 with the center point of the shaft hole 101 as the center in the upper part.

[0083] Based on this, in this application, the lower end of the rotating plate 201 is rotatably connected to the lower part of the fixed plate 10 through the rotating shaft 50, which is arranged in the front-back direction and passes through the shaft hole 101. The upper part of the rear end face of the rotating plate 201 has a locking hole 2011 facing the arc groove 102. The locking nut 60 is abutted against the rear end face of the fixed plate 10 and passes through the arc groove 102 and is screwed into the locking hole 2011.

[0084] When the locking nut 60 is loosened, the rotating plate 201 can rotate around the rotating shaft 50 and in contact with the front end face of the fixing plate 10, so that the lower end of the glue injection needle 40 can be oriented at an adjustable angle.

[0085] Therefore, it is clear that for different injection molds, which may have irregular shapes, the upper injection port may not be set directly upwards. That is to say, it may be set at an angle so that it faces the upper left or upper right. In this case, the locking nut 60 can be loosened and the rotating plate 201 can be rotated around the rotating shaft 50 so that the lower end of the injection needle 40 is aligned with the opening direction of the upper injection port of the irregularly shaped injection mold. Then, the locking nut 60 is tightened again, and under the control of the up and down moving mechanism 20, the injection barrel 30 and the injection needle 40 connected to it are moved downwards to a suitable height so that the lower end of the injection needle 40 can just extend into the injection port of the injection mold of the appropriate height.

[0086] Furthermore, preferably, in this technical solution, the reference is still made. Figures 1 to 3As shown, according to one embodiment of the present utility model, the upper part of the front end face of the fixing plate 10 is provided with an angle measuring scale line 103 for indicating the angle of the lower end of the glue injection needle 40 around the arc groove 102, and the angle measuring scale line 103 is provided with an angle measuring value.

[0087] Based on this, in this application, the upper part of the rotating plate 201 is provided with an indicator arrow 2012 pointing to the measuring scale line 103, and the central axis of the indicator arrow 2012 is parallel to the central axis of the dispensing needle 40 in the front-back direction.

[0088] Therefore, for injection molds with different opening orientations, the direction of the injection needle 40 can be adjusted to inject glue into the mold cavity of the injection mold with the different shape. When adjusting the direction of the injection needle 40, since this application is provided with the angle scale line 103, the angle value and the indicator arrow 2012, the angle of the injection needle 40 can be accurately measured in a basically consistent manner, which makes it easy to record and archive. This provides data reference for subsequent injection of glue into the mold cavity of the same irregular shape, so that the direction of the injection needle 40 can be adjusted less effortfully, making this application more convenient and less labor-intensive to use.

[0089] Furthermore, through the above-mentioned optimized design, the overall performance of this application can be effectively improved.

[0090] Furthermore, in specific implementation, we will continue to refer to... Figures 1 to 3 As shown, according to one embodiment of the present invention, the glue injection barrel 30 has a glue inlet 301 at the top and a glue guide head 302 at the bottom. The glue guide head 302 is connected to the glue injection needle 40 by insertion or thread.

[0091] Therefore, a certain amount of resin can be pre-filled into the glue injection tank 30 through the glue inlet 301, and the glue injection needle 40 can be easily disassembled and replaced when it is plugged into or threadedly connected to the glue guide head 302.

[0092] Furthermore, in a specific implementation, according to one embodiment of the present utility model, the up-and-down moving mechanism 20 also has a movable frame 202 that can move up and down under its control, and the movable frame 202 is provided with a first locking ring 2021 and a second locking ring 2022 from top to bottom;

[0093] Based on this, in this application, the glue dispensing bucket 30 is detachably clamped to the first retaining ring 2021, and the glue guide head 302 is detachably clamped to the second retaining ring 2022.

[0094] Preferably, in this technical solution, the outer wall of the first locking ring 2021 is provided with a first locking knob for locking the glue dispensing barrel 30, and the outer wall of the second locking ring 2022 is provided with a second locking knob for locking the glue guide head 302. In this way, the glue dispensing barrel 30 can be easily disassembled and replaced when the first locking knob and the second locking knob are loosened.

[0095] Furthermore, in specific implementation, it is still necessary to refer to... Figures 1 to 3 As shown, according to one embodiment of the present invention, the upper part of the rotating plate 201 is provided with an upper stop limit rod 2013 for blocking the moving frame 202 from moving upward to the upper limit position; the lower part of the rotating plate 201 is provided with a lower stop limit rod 2014 for blocking the moving frame 202 from moving downward to the lower limit position.

[0096] The upper stop limit rod 2013 and the lower stop limit rod 2014 are vertically opposite each other; based on this, in this application, the movable frame 202 is provided with a stop plate 2023 located between the upper stop limit rod 2013 and the lower stop limit rod 2014.

[0097] When the up-and-down moving mechanism 20 drives the moving frame 202 to move upward to the upper limit position, the upper end face of the stop plate 2023 abuts against the lower end of the upper stop limit rod 2013; when the up-and-down moving mechanism 20 drives the moving frame 202 to move downward to the lower limit position, the lower end face of the stop plate 2023 abuts against the upper end of the lower stop limit rod 2014.

[0098] Therefore, by setting the upper stop limit rod 2013 and the lower stop limit rod 2014, it is possible to control the moving frame 202 to only move upward to the upper limit position and not to move further upward, and it is also easy to control the moving frame 202 to only move downward to the lower limit position and not to move further downward. This makes the vertical movement displacement of the moving frame 202 controllable, so that the vertical movement range of the glue injection barrel 30 and the glue injection needle 40 connected to it is controllable and not easily damaged due to large vertical movement range.

[0099] Furthermore, through the above-mentioned optimized design, the overall performance of this application can be further improved.

[0100] Furthermore, in a specific implementation, according to one embodiment of the present utility model, the lower rear part of the fixing plate 10 is connected to a horizontal plate 104, and the horizontal plate 104 has a fixing groove 1041 extending through its upper and lower end faces along the front-back direction.

[0101] Therefore, when a fixing bolt is inserted into a fixing hole on a platform in the fixing groove 1041, the front and rear positions of the horizontal plate 104 can be adjusted by using the fixing groove 1041 before the fixing bolt is fully tightened. This makes the front and rear positions of the fixing plate 10, the glue injection bucket 30 fixed thereon, and the glue injection needle 40 connected thereto adjustable, which makes the application more flexible and applicable.

[0102] Furthermore, in this technical solution, according to an embodiment of the present utility model, the left and right sides of the rear middle of the fixing plate 10 are respectively provided with connecting ribs 105 connected to the horizontal plate 104.

[0103] Thus, the connection between the fixed plate 10 and the horizontal plate 104 is more secure, resulting in better overall stability of the application.

[0104] It should be added that, in a specific implementation, according to one embodiment of this utility model, the up-and-down moving mechanism 20 is a cylinder-driven linear module or a screw-driven linear module, which are common linear guide modules in the prior art. Therefore, its details will not be described in detail here.

[0105] Other embodiments, etc., will not be described here.

[0106] In summary, the adjustable needle position adhesive delivery device 1000 provided in this application, in specific implementation, uses the glue injection tank 30 and the glue injection needle 40 connected thereto to fill the resin adhesive into the mold cavity of the injection mold. It saves effort by eliminating the need for manual handling and also makes it easy to control the amount of resin adhesive injected. In specific implementation, a capacity scale can be set on the outer wall of the glue injection tank 30 from top to bottom. The amount of resin adhesive to be injected into the mold cavity of the injection mold each time can be controlled by observing the height of the resin adhesive level in the glue injection tank 30 and controlling the opening and closing of the switch valve installed at the bottom of the tank.

[0107] Furthermore, for injection molds with a straight upward injection port, regardless of the height of the injection port, the injection barrel 30 and the injection needle 40 connected to it can be moved up and down to a suitable height under the control of the up-and-down moving mechanism 20. This ensures that the lower end of the injection needle 40 can just extend into the injection port of the injection mold at the appropriate height, preventing glue leakage from the injection port of the injection mold due to the lower end of the injection needle 40 being too far away. As a result, this application is flexible, reliable, and highly adaptable to use.

[0108] Furthermore, for different injection molds, which may have irregular shapes, the upper injection port may not be set directly upwards. That is to say, it may be set at an angle so that it faces the upper left or upper right. In this case, the rotating plate 201 can be rotated along the front end face of the fixed plate 10 so that the up-down moving mechanism 20 rotates to a suitable angle, thereby driving the lower end of the glue injection needle 40 fixed on it to face the appropriate angle, so that the installed glue dispensing needle can be adapted to extend into the mold cavity of the injection mold where the injection port is set at an angle upwards. In this way, the operation of this application is more flexible and the adaptability is also stronger.

[0109] For the injection molds with different opening orientations, the direction of the injection needle 40 can be adjusted to inject glue into the mold cavity of the injection mold with the different shape. When adjusting the direction of the injection needle 40, since this application is provided with the angle scale line 103, the angle value and the indicator arrow 2012, the angle of the injection needle 40 can be accurately measured in combination, which makes it easy to record and archive. This provides data reference for subsequent injection of glue into the mold cavity of the same irregular shape, so that the direction of the injection needle 40 can be adjusted less effortfully. Therefore, this application is more convenient and less laborious to use.

[0110] Furthermore, by setting the upper stop limit rod 2013 and the lower stop limit rod 2014, it is possible to control the moving frame 202 to only move upward to the upper limit position and not to move further upward, and it is also easy to control the moving frame 202 to only move downward to the lower limit position and not to move further downward. This makes the vertical movement displacement of the moving frame 202 controllable, so that the vertical movement range of the glue injection barrel 30 and the glue injection needle 40 connected to it is controllable and not easily damaged due to large vertical movement range.

[0111] Furthermore, the adjustable needle position adhesive delivery device 1000 provided in this application is indeed highly practical and has excellent performance, which makes this application inherently valuable for market promotion and will certainly be very popular and widely adopted.
