Description

Technical Field

[0001] This utility model is an optical coupler dispensing device, belonging to the field of optical coupler processing technology. Background Technology

[0002] In the production and assembly process of optocouplers, the dispensing operation is a crucial step in ensuring component fixation and performance stability. A cylinder-driven dispensing mechanism is commonly used to achieve precise dispensing. The core working logic of this mechanism is that the extension and retraction of the cylinder drives the dispensing head, which carries the dispensing nozzle, to perform a reciprocating linear motion. This allows the dispensing nozzle to flexibly switch between two states: close to the optocoupler (performing the dispensing operation) and away from the optocoupler (resetting and standing by), ensuring that the adhesive is accurately applied to the preset location. To achieve a continuous supply of adhesive, the dispensing head is connected to a rubber hose that delivers the adhesive via a rotary joint. The rotary joint is originally designed to adapt to the movement of the dispensing head and reduce the torsional stress on the rubber hose.

[0003] In actual operation, because the dispensing head needs to move back and forth frequently under the drive of the cylinder, and the movement stroke and direction are relatively fixed, the part of the rubber hose near the dispensing head will be constantly pulled and bent with the movement of the dispensing head. Due to the lack of guiding measures, this area of ​​the rubber hose is prone to excessive bending. This excessive bending will have a negative impact on the delivery of adhesive. The internal channel of the rubber hose at the bend becomes narrower, the flow resistance of the adhesive increases, the originally stable adhesive delivery rate will fluctuate, and even adhesive breakage will occur, directly affecting the accuracy of the dispensing amount and causing uneven adhesive layer thickness of the optocoupler. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an optical coupler dispensing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an optocoupler dispensing device, comprising: Seat; A slide block is slidably mounted on one side of a carrier, and a drive component for driving the slide block to move is mounted on the side of the carrier opposite to the slide block. A dispensing head is connected to a slide block. One end of the dispensing head is equipped with a dispensing nozzle, and a rubber hose is connected to the dispensing head via a rotary joint. The disc has an annular groove machined on its annular side for storing a rubber hose. The rubber hose is connected to the disc via a limiting member. The rubber hose enters the annular groove tangentially to the disc. The disc is connected to a carrier via an adjusting member.

[0006] Furthermore, the driving component includes a cylinder, and the side of the carrier facing away from the slide is connected to the cylinder via a bracket. A connecting arm is installed on the movable end of the cylinder. A guide groove is provided on one side of the carrier. The guide groove is arranged along the length direction of the cylinder. The end of the connecting arm away from the cylinder passes through the guide groove and is connected to the slide via a screw.

[0007] Furthermore, a slider is installed on the side of the slide facing the carrier, and a linear guide rail is inserted inside the slider. The linear guide rail is connected to the carrier by screws, and the linear guide rail is arranged parallel to the guide groove.

[0008] Furthermore, a pressure plate is installed on the end of the slide away from the dispensing head by screws, an upper support is installed on the end of the carrier near the cylinder, a first blocking head that cooperates with the pressure plate is connected to the upper support, and a lower support is installed on the end of the carrier away from the cylinder, a second blocking head that cooperates with the pressure plate is connected to the lower support.

[0009] Furthermore, the limiting component includes a sleeve, which is fitted onto the rubber hose. The sleeve is arranged along the tangential direction of the disc, and a connecting plate is fixedly connected to the outer surface of the sleeve. The end of the connecting plate away from the sleeve is connected to the disc by a screw.

[0010] Furthermore, the adjusting component includes a screw, which is installed at the center of one side of the disc, and a support arm is installed on one side of the carrier. An elongated opening is provided on one side of the support arm, and the end of the screw away from the disc passes through the elongated opening. Two nuts are threaded onto the screw, and the two nuts are located on both sides of the support arm.

[0011] Furthermore, a rectangular block is fitted onto the end of the screw away from the disc and is fixedly connected to the screw. The rectangular block is slidably installed inside the elongated opening, and the two sides of the rectangular block are respectively attached to the two inner walls of the elongated opening.

[0012] Furthermore, a connecting seat is installed at one end of the slide, and the dispensing head is connected to the connecting seat by screws.

[0013] The beneficial effects of this utility model are: The annular groove of the disc provides storage and guidance space for the rubber hose, and the rubber hose enters the annular groove tangentially, which can follow the reciprocating movement trajectory of the dispensing head, avoiding sharp-angle bends or folds in the area of ​​the rubber hose near the dispensing head, thus solving the problem of channel compression and deformation at the source and ensuring smooth flow of adhesive.

[0014] The sleeve is fitted over the rubber hose and fixed to the disc by the connecting plate. This not only restricts the displacement of the rubber hose, but also guides the rubber hose to move along the preset path, reducing the pulling and shaking of the rubber hose when the dispensing head moves, and further avoiding excessive bending.

[0015] By tightening the nuts on both sides of the screw, the position of the disc can be adjusted along the long oval opening of the support arm, flexibly adapting to the length of the rubber hose and the travel of the dispensing head, ensuring that the rubber hose is always in the best guiding state and improving adaptability.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3 This utility model provides a technical solution: an optocoupler dispensing device, including a carrier 1, with a guide groove 11 on one side of the carrier 1; a slider 21 is mounted on the side of the slide 2 facing the carrier 1, and a linear guide rail 22 is inserted inside the slider 21. The linear guide rail 22 is connected to the carrier 1 by screws, and the linear guide rail 22 is arranged parallel to the guide groove 11. The slider 21 and the linear guide rail 22 cooperate with each other to allow the slide 2 to slide on one side of the carrier 1, and to limit the movement trajectory of the slide 2.

[0019] A connecting seat 23 is installed at one end of the slide 2, and the dispensing head 5 is connected to the connecting seat 23 by screws. A dispensing nozzle 51 is installed at one end of the dispensing head 5, and a rubber hose 53 is connected to the dispensing head 5 by a rotary joint 52. A cylinder 3 is connected to the side of the carrier 1 away from the slide 2 by a bracket 32. A connecting arm 31 is installed at the movable end of the cylinder 3. A guide groove 11 is arranged along the length of the cylinder 3. The end of the connecting arm 31 away from the cylinder 3 passes through the guide groove 11 and is connected to the slide 2 by screws. When the cylinder 3 extends or retracts, it drives the connecting arm 31 to move along the guide groove 11, and the slide 2 moves synchronously along the linear guide rail 22. This allows for adjustment of the relative position of the dispensing head 5 and the optocoupler as needed, achieving precise dispensing.

[0020] See Figures 1-4 The disc 6 has an annular groove 63 machined on its annular side for storing a rubber hose 53. A sleeve 62 is fitted onto the rubber hose 53, and the sleeve 62 is arranged along the tangential direction of the disc 6. A connecting plate 61 is fixedly connected to the outer surface of the sleeve 62, and the end of the connecting plate 61 away from the sleeve 62 is connected to the disc 6 by screws. The connecting plate 61 serves to connect the sleeve 62 and the disc 6. The sleeve 62 and the connecting plate 61 work together to allow the rubber hose 53 to enter the annular groove 63 in the tangential direction of the disc 6. The annular groove 63 of the disc 6 provides storage and guiding space for the rubber hose 53, which can follow the reciprocating movement trajectory of the dispensing head 5 and prevent the rubber hose 53 from being bent at sharp angles or folded in the area near the dispensing head 5. This solves the problem of channel compression and deformation from the root and ensures smooth flow of adhesive. The sleeve 62 is fitted over the rubber hose 53 and fixed to the disc 6 by the connecting plate 61. This not only restricts the displacement of the rubber hose 53, but also guides the rubber hose 53 to move along the preset path, reducing the pulling and shaking of the rubber hose 53 when the dispensing head 5 moves, and further avoiding excessive bending.

[0021] See Figures 1-3 A pressure plate 42 is screwed onto the end of the slide block 2 furthest from the dispensing head 5. An upper support lug 4 is mounted on the end of the carrier 1 closest to the cylinder 3, and a first blocking head 41, which mates with the pressure plate 42, is connected to the upper support lug 4. A lower support lug 43 is mounted on the end of the carrier 1 furthest from the cylinder 3, and a second blocking head 44, which mates with the pressure plate 42, is connected to the lower support lug 43. When the slide block 2 moves under the drive of the cylinder 3, the pressure plate 42 moves synchronously with the slide block 2. When the pressure plate 42 contacts the first blocking head 41 or the second blocking head 44, it limits the range of movement of the slide block 2, preventing excessive movement that could damage the components.

[0022] See Figures 1-4A screw 64 is installed in the center of one side of the disc 6; a support arm 65 is installed on one side of the carrier 1, and an elongated oval opening 67 is opened on one side of the support arm 65; the end of the screw 64 away from the disc 6 passes through the elongated oval opening 67, and two nuts 66 are threaded onto the screw 64, which are located on both sides of the support arm 65; a rectangular block 68 is fitted onto the end of the screw 64 away from the disc 6 and is fixed to the screw 64. The rectangular block 68 is slidably installed in the elongated oval opening 67, and its two sides are respectively in contact with the two inner walls of the elongated oval opening 67 to prevent the disc 6 from rotating arbitrarily. By turning the nuts 66 on both sides of the screw 64, the position of the disc 6 can be adjusted along the elongated oval opening 67 of the support arm 65, flexibly adapting to the length of the rubber hose 53 and the travel of the dispensing head 5, ensuring that the rubber hose 53 is always in the best guiding state and improving adaptability.
