Description

Technical Field

[0001] This utility model relates to the field of precision dispensing technology, and in particular to a joint dispensing fixture. Background Technology

[0002] The joint dispensing fixture is a device used to precisely control the delivery and dispensing process of adhesive. It is widely used in precision assembly and repair work in industries such as electronics, automotive, and medical. In these industries, dispensing operations usually require high precision and stability to ensure that the adhesive is applied only to the designated location and to avoid leakage or waste.

[0003] Traditional joint dispensing fixtures mainly consist of an adhesive storage device, a delivery pipeline, a dispensing head, an adjustment device, and a support frame. Its working principle is to deliver the adhesive to the dispensing head through the adhesive storage device, and then control the flow rate and pressure of the adhesive through the adjustment device to accurately control the amount and position of dispensing. The dispensing head releases the adhesive according to the instructions of the control device to ensure that the adhesive is accurately applied to the joint of the workpiece.

[0004] Traditional dispensing head designs are not perfect, lacking effective adhesive backflow prevention mechanisms or sealing designs. This results in adhesive still flowing out of the dispensing head after dispensing, causing excessive adhesive to drip onto the outside of the workpiece and affecting the connection of the joint. To address this issue, a joint dispensing fixture is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a joint dispensing fixture, which aims to improve the problem of glue leakage that occurs when the dispensing is completed in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A joint dispensing fixture includes a fixed shell, an infusion tube fixedly connected to the inner wall of the fixed shell, four fixed blocks fixedly connected to the inner wall of the infusion tube, a sliding ring fixedly connected to the adjacent sides of the four fixed blocks, a sliding column slidably connected to the inner wall of the sliding ring, a baffle fixedly connected to the outer wall of the sliding column, a blocking block fixedly connected to the bottom of the baffle, a spring sleeved on the outer wall of the sliding column, a top head fixedly connected to the bottom of the sliding column, a baffle plate fixedly connected to the top of the sliding column, and a detachable component provided on the top of the fixed shell.

[0008] As a further description of the above technical solution:

[0009] The detachable component includes a connecting block, the top of which is fixedly connected to a connecting shell, and the inner wall of the connecting shell is threaded with a threaded pin.

[0010] As a further description of the above technical solution:

[0011] A connecting rod is slidably connected to the inner wall of the connecting shell, and a locking block is fixedly connected to the bottom of the connecting rod;

[0012] As a further description of the above technical solution:

[0013] The inner wall of the connecting shell is provided with a sliding groove, and one side of the fixed shell is provided with a liquid inlet;

[0014] As a further description of the above technical solution:

[0015] The infusion tube is fixedly connected to the bottom of the infusion tube, and the top is made of rubber.

[0016] As a further description of the above technical solution:

[0017] One end of the spring is fixedly connected to the bottom of the sliding ring, and the other end of the spring is fixedly connected to the top of the baffle.

[0018] As a further description of the above technical solution:

[0019] The outer wall of the plug contacts the bottom of the inner wall of the infusion tube, and the outer wall of the threaded pin is threaded to the inner wall of the connecting rod.

[0020] As a further description of the above technical solution:

[0021] The bottom of the connecting block is fixedly connected to the top of the fixed shell, and the outer wall of the card block is slidably connected to the inner wall of the connecting shell.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when the mandrel contacts the workpiece, pressure is applied and the mandrel moves upward, thereby driving the sliding column to move upward. During the upward movement of the sliding column, the blockage of the outlet inside the infusion tube is released, allowing the adhesive to flow smoothly through the infusion tube into the outlet tube, thereby achieving dispensing of adhesive to the workpiece. When the mandrel leaves the workpiece, the spring is compressed and generates elastic force, pushing the sliding column downward. When the sliding column moves downward, it drives the block to move downward as well. The block can tightly seal the inner wall of the infusion tube, cutting off the flow of adhesive and thus preventing adhesive leakage.

[0024] 2. In this utility model, by turning the threaded pin, the threaded pin can be removed from the inside of the connecting rod, thereby allowing the connecting rod to rotate. The rotation of the connecting rod can drive the locking block to rotate inside the connecting shell. When the locking block is flush with the slide groove, the connecting rod can drive the locking block to be removed from the inner wall of the connecting shell. The connecting rod and the locking block can be positioned with the connecting shell and the slide groove. When the locking block rotates inside the fixed shell, it can lock the connecting rod and the connecting shell. Then, the threaded pin is threaded to the inner wall of the connecting shell and the connecting rod, further reinforcing the locking of the connecting rod. Attached Figure Description

[0031] 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.

[0032] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a joint dispensing fixture, including a fixed shell 1, which provides stable support and protection to ensure the positioning and normal operation of subsequent components. An infusion tube 2 is fixedly connected to the inner wall of the fixed shell 1. The infusion tube 2 is used to transport dispensing liquid to ensure continuous flow of liquid. Four fixing blocks 3 are fixedly connected to the inner wall of the infusion tube 2. The four fixing blocks 3 can ensure that the subsequent components do not shift during operation, thereby maintaining the stability of the dispensing process. Sliding rings 4 are fixedly connected to the adjacent sides of the four fixing blocks 3. The function of the sliding rings 4 is to reduce friction between components and ensure smooth sliding function.

[0033] A sliding column 5 is slidably connected to the inner wall of the sliding ring 4. The sliding column 5 can drive the movement of subsequent components on the inner wall of the sliding ring 4, thereby achieving flexible dispensing control. A baffle 7 is fixedly connected to the outer wall of the sliding column 5. The baffle 7 can drive the movement of subsequent components. A block 8 is fixedly connected to the bottom of the baffle 7. The block 8 can effectively prevent liquid from overflowing. A spring 9 is sleeved on the outer wall of the sliding column 5. The spring 9 on the outer wall of the sliding column 5 provides a reaction force, so that the sliding column 5 can return to the initial position after pressure is applied, thereby improving the flexibility of use and the automatic return function. A top head 11 is fixedly connected to the bottom of the sliding column 5. The top head 11 is used to contact the workpiece to accurately control the dispensing accuracy. A baffle 6 is fixedly connected to the top of the sliding column 5. The baffle 6 can prevent the sliding column 5 from moving excessively. A detachable component is provided on the top of the fixed shell 1.

[0034] Reference Figures 1 to 3 The detachable component includes a connecting block 12, which serves to fix and connect subsequent components, allowing each component to be securely installed together. A connecting shell 13 is fixedly connected to the top of the connecting block 12, providing additional support and accommodating space, and providing a stable interface for subsequent connections. A threaded nail 14 is threadedly connected to the inner wall of the connecting shell 13, ensuring a tight connection between the connecting shell 13 and subsequent components and preventing loosening. A connecting rod 16 is slidably connected to the inner wall of the connecting shell 13, and a locking block 17 is fixedly connected to the bottom of the connecting rod 16. The locking block 17 locks the bottom inner wall of the connecting shell 13, ensuring that the connecting rod 16 can be firmly fixed and preventing loosening.

[0035] The inner wall of the connecting shell 13 is provided with a sliding groove 15, which provides a stable sliding trajectory for the connecting rod 16 and the locking block 17, reduces friction and wear, and ensures smooth sliding action. A liquid inlet 18 is provided on one side of the fixed shell 1. The liquid inlet 18 is used to connect to an external liquid source to ensure the liquid supply during the dispensing process. The bottom of the infusion pipe 2 is fixedly connected to the liquid outlet pipe 10, which ensures that the liquid flows out smoothly from the tooling and avoids blockage. The top head 11 is made of rubber material. The top head 11 is made of rubber material, which has good flexibility and pressure resistance, and can effectively contact the workpiece to provide a stable dispensing effect while reducing damage to the surface of the workpiece.

[0036] Working principle: By pressing the top head 11 against the workpiece, the top head 11 moves upward. During the upward movement of the top head 11, it can drive the sliding column 5 to move upward. The upward movement of the sliding column 5 can release the blockage of the internal outlet of the infusion tube 2, allowing the adhesive to flow into the internal outlet tube 10 through the internal outlet tube 2, thus enabling the adhesive to be dispensed onto the workpiece. When the top head 11 leaves the workpiece, the elastic force generated by the baffle 7 compressing the spring 9 upward can push the sliding column 5 downward. During the downward movement of the sliding column 5, it can drive the block 8 to move downward. The block 8 can seal the inner wall of the infusion tube 2, thereby enabling the device to dispense adhesive better and preventing adhesive leakage.

[0037] By turning the threaded pin 14, the threaded pin 14 can be removed from the inside of the connecting rod 16, thereby allowing the connecting rod 16 to rotate. The rotation of the connecting rod 16 can drive the locking block 17 to rotate inside the connecting shell 13. When the locking block 17 is flush with the slide groove 15, the connecting rod 16 can drive the locking block 17 to be removed from the inner wall of the connecting shell 13. The connecting rod 16 and the locking block 17 can be positioned with the connecting shell 13 and the slide groove 15. When the locking block 17 rotates inside the fixed shell 1, it can lock the connecting rod 16 to the connecting shell 13. Then, the threaded pin 14 is threadedly connected to the inner wall of the connecting shell 13 and the connecting rod 16, further reinforcing the locking of the connecting rod 16.

[0038] 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.
