The dispensing needle limiting and fixing device for dispensing equipment disclosed in this utility model mainly consists of dispensing equipment, a sliding frame, a glue bottle, a dispensing syringe, a positioning mechanism, and a self-lubricating mechanism.

[0003] In existing technologies, the dispensing needle limiting and fixing device is usually directly installed on the dispensing equipment. The operator fixes the glue bottle in the corresponding position, aligns the dispensing syringe with the area to be dispensed, and performs the dispensing operation through the control commands of the equipment.

[0004] However, due to the lack of precise positioning and stable limiting structure, it is difficult to ensure accurate resetting when adjusting the position of the dispensing syringe, resulting in deviations in the positional accuracy of each dispensing, making it difficult to guarantee vertical accuracy and directly affecting the uniformity of dispensing. Therefore, a dispensing needle limiting and fixing device for dispensing equipment is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a dispensing needle limiting and fixing device for dispensing equipment, which aims to solve the problem of deviation in vertical accuracy in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dispensing needle limiting and fixing device for a dispensing equipment, comprising a dispensing equipment, a sliding frame slidably connected to the side wall of the dispensing equipment, a glue bottle fixedly connected to the outer wall of the sliding frame, a dispensing syringe fixedly connected to the bottom of the glue bottle, a positioning mechanism provided above the dispensing equipment, the positioning mechanism comprising a threaded plate, a screw threadedly connected to the inner wall of the threaded plate, a positioning plate fixedly connected to the bottom outer wall of the threaded plate, and a guide block hinged to the top of the threaded plate.

[0007] As a further description of the above technical solution: a fixing plate is fixedly connected to the outer wall of the glue bottle, and the outer wall of the screw is rotatably connected to the inner wall of the fixing plate.

[0008] As a further description of the above technical solution: the screw is a bidirectional threaded rod.

[0009] As a further description of the above technical solution: a limiting rod is fixedly connected to the outer wall of the glue bottle, and the inner wall of the threaded plate is slidably connected to the outer wall of the limiting rod.

[0010] As a further description of the above technical solution: an anti-deviation box is fixedly connected to the outer wall of the glue bottle, and the outer wall of the guide block is slidably connected to the inner wall of the anti-deviation box.

[0011] As a further description of the above technical solution: a vertical rod is fixedly connected to the inner wall of the anti-deviation box, and the outer wall of the vertical rod is slidably connected to the inner wall of the guide block.

[0012] As a further description of the above technical solution: a flexible pad is provided on the arc-shaped clamping surface of the positioning plate.

[0013] As a further description of the above technical solution: a self-lubricating mechanism is provided on the outer wall of the glue bottle. The self-lubricating mechanism includes an oil storage box. The bottom of the oil storage box is fixedly connected to the top of the glue bottle. A connecting pipe is fixedly connected to the inner wall of the oil storage box. The connecting pipe is fixedly connected to the inner wall of the anti-deviation box.

[0014] As a further description of the above technical solution: a connecting plate is fixedly connected to the outer wall of the guide block.

[0015] As a further description of the above technical solution: a control switch is fixedly connected to the outer wall of the oil storage box, and a compression head is fixedly connected to the outer wall of the connecting plate.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, when it is necessary to fix the dispensing syringe, the screw is rotated to bring the positioning plates closer together to clamp the dispensing syringe. The guide block hinged at the top of the threaded plate slides in the anti-deviation box. The vertical rod in the anti-deviation box further restricts the movement direction of the guide block to prevent the threaded plate from deviating. This ensures that the positioning plate accurately clamps and positions the dispensing syringe, improving the stability of the dispensing syringe during operation and thus improving the accuracy and quality of dispensing.

[0018] 2. In this utility model, when the clamping of the dispensing syringe is released, the threaded plate moves upward, causing the guide block and connecting plate to move downward. The extrusion head on the connecting plate presses the control switch on the outer wall of the oil storage box, opening the valve at the connecting pipe of the oil storage box. The lubricating oil in the oil storage box flows down to the vertical rod through the connecting pipe, lubricating the sliding part between the vertical rod and the guide block. When the dispensing syringe is clamped again, the threaded plate moves downward, causing the guide block and connecting plate to move upward. The extrusion head presses the control switch again, closing the valve and stopping the oil injection. This eliminates the need for frequent manual addition of lubricating oil, reducing maintenance costs, reducing wear on components caused by friction, and extending the overall service life of the device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a dispensing needle limiting and fixing device for a dispensing equipment, comprising a dispensing equipment 1, a sliding frame 6 slidably connected to the side wall of the dispensing equipment 1, a glue bottle 2 fixedly connected to the outer wall of the sliding frame 6, the sliding displacement of the sliding frame 6 can drive the glue bottle 2 to move, a dispensing syringe 3 fixedly connected to the bottom of the glue bottle 2, the dispensing syringe 3 being used for dispensing glue, and a positioning mechanism 4 provided above the dispensing equipment 1, the positioning mechanism 4 limiting and fixing the dispensing syringe 3, the positioning mechanism 4 including a threaded plate 4. 03. The inner wall of the threaded plate 403 is threaded with a screw 402. The rotation of the screw 402 can drive the threaded plate 403 to move. A positioning plate 404 is fixedly connected to the bottom outer wall of the threaded plate 403. The displacement of the two threaded plates 403 causes the two positioning plates 404 to move closer or further apart. Under the action of moving closer together, it plays a role in limiting and fixing the dispensing syringe 3. A guide block 408 is hinged to the top of the threaded plate 403. The guide block 408 plays a role in correcting the deviation of the two threaded plates 403.

[0027] Reference Figure 1 - Figure 3 A fixing plate 401 is fixedly connected to the outer wall of the glue bottle 2. The outer wall of the screw 402 is rotatably connected to the inner wall of the fixing plate 401. The fixing plate 401 provides a limiting and load-bearing function for the screw 402. The screw 402 is a bidirectional threaded rod. Two threaded plates 403 are symmetrically arranged on the positive and negative threads of the bidirectional threaded rod. A limiting rod 405 is fixedly connected to the outer wall of the glue bottle 2. The limiting rod 405 provides a limiting and load-bearing function for the two threaded plates 403. The inner wall of the threaded plate 403 is slidably connected to the outer wall of the limiting rod 405. An anti-deviation box 406 is fixedly connected to the outer wall of the glue bottle 2. The outer wall of the guide block 408 is slidably connected to the inner wall of the anti-deviation box 406, which limits the guide block 408. A vertical rod 407 is fixedly connected to the inner wall of the anti-deviation box 406, which further limits the guide block 408, prevents the guide block 408 from shifting, and allows the guide block 408 to slide vertically up and down. The outer wall of the vertical rod 407 is slidably connected to the inner wall of the guide block 408. A flexible pad is provided on the arc-shaped clamping surface of the positioning plate 404. The flexible pad can provide a flexible clamping effect when the two positioning plates 404 are close to each other to clamp the dispensing syringe 3, avoiding damage.

[0028] Reference Figure 2 - Figure 4 A self-lubricating mechanism 5 is provided on the outer wall of the glue bottle 2. The self-lubricating mechanism 5 includes an oil storage box 501, which is used to fill lubricating oil through the movable door on the back. The bottom of the oil storage box 501 is fixedly connected to the top of the glue bottle 2. A connecting pipe 503 is fixedly connected to the inner wall of the oil storage box 501. The connecting pipe 503 is fixedly connected to the inner wall of the anti-deviation box 406. The connecting pipe 503 can allow the lubricating oil to flow onto the vertical rod 407, thus achieving a lubrication effect. A connecting plate 502 is fixedly connected to the outer wall of the guide block 408. The displacement of the guide block 408 can carry... The movable connecting plate 502 is displaced. A control switch 504 is fixedly connected to the outer wall of the oil storage box 501. A squeezing head 505 is fixedly connected to the outer wall of the connecting plate 502. When the connecting plate 502 moves upward, it will squeeze the control switch 504 through the squeezing head 505, so that the valve at the oil storage box 501 connecting pipe 503 is closed. When the dispensing syringe 3 is released from the clamp, the connecting plate 502 will move downward with the guide block 408, and then use the squeezing head 505 to move downward to squeeze the control switch 504, so that the valve is opened and oil lubrication can be performed.

[0029] Working principle: First, by manually rotating the screw 402, the two threaded plates 403 move along the axial direction of the screw 402, causing the bottom positioning plates 404 to move closer or further apart. When it is necessary to fix the dispensing syringe 3, rotating the screw 402 makes the two positioning plates 404 move closer together. The arc-shaped clamping surface of the positioning plate 404 is provided with a flexible pad, which can flexibly clamp the dispensing syringe 3 to avoid damage, thereby achieving the limiting and fixing of the dispensing syringe 3. During the movement of the threaded plate 403, the limiting rod 405 plays a limiting and load-bearing role, ensuring that the threaded plate 403 moves smoothly. At the same time, the guide block 408 is hinged to the top of the threaded plate 403 and slides in the anti-deviation box 406. The vertical rod 407 in the anti-deviation box 406 further restricts the movement direction of the guide block 408, making it only able to slide vertically up and down, preventing the threaded plate 403 from deviating, ensuring that the positioning plate 404 accurately clamps and positions the dispensing syringe 3, ensuring accuracy during use.

[0030] When the guide block 408 moves with the threaded plate 403, the connecting plate 502 on the outer wall of the guide block 408 also moves accordingly. When it is necessary to release the clamping of the dispensing syringe 3, the threaded plates 403 move away from each other under the rotation of the bidirectional threaded rod, causing the guide block 408 and the connecting plate 502 to move downward. The extrusion head 505 on the connecting plate 502 will press the control switch 504 on the outer wall of the oil storage box 501, causing the valve at the connecting pipe 503 of the oil storage box 501 to open. The lubricating oil in the oil storage box 501 flows down to the vertical rod 407 through the connecting pipe 503, lubricating the sliding part between the vertical rod 407 and the guide block 408 and reducing friction. When the dispensing syringe 3 is clamped again, the bidirectional threaded rod is rotated in the opposite direction, causing the threaded plates 403 to move closer to each other, causing the guide block 408 and the connecting plate 502 to move upward. The extrusion head 505 on the connecting plate 502 will press the control switch 504 again, causing the valve to close and stopping the oil injection, thus realizing the function of automatic control lubrication.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
