Description

Technical Field

[0001] This utility model belongs to the field of fluid dispensing machine technology, and in particular relates to an auxiliary component for a fluid dispensing machine. Background Technology

[0002] Fluid dispensing machines, also known as coating machines, dripping machines, glue applicators, or potting machines, are automated machines specifically designed to control fluids and precisely dispense or coat them onto the surface or interior of products. They can achieve three-dimensional and four-dimensional path dispensing, precise positioning, accurate glue control, and ensure consistent glue dots. Fluid dispensing machines play a vital role in numerous industrial production sectors, including but not limited to the electronics, lighting, automotive, and industrial electrical industries. Based on factors such as control methods, structural forms, and application scenarios, fluid dispensing machines can be categorized into various types, such as single-component dispensing machines, two-component dispensing machines, automatic dispensing machines, and semi-automatic dispensing machines. When selecting a model, it is necessary to consider the basic characteristics of the adhesive (such as type, volume ratio, viscosity and density, curing time, and packaging method) as well as the specific requirements of the dispensing process (such as dispensing accuracy, adhesive application, and operation method).

[0003] The problems with the existing technology are: without clamping and positioning, the workpiece may move or shift during the dispensing process, resulting in the glue not being accurately applied to the predetermined position. Furthermore, the instability of the workpiece may cause changes in the distance between the dispensing head and the workpiece, thereby affecting the glue flow rate and coating amount, resulting in uneven glue application. Utility Model Content

This solves the problem that without clamping and positioning, the workpiece may move or shift during the dispensing process, resulting in the glue not being accurately applied to the predetermined position. Furthermore, the instability of the workpiece may cause changes in the distance between the dispensing head and the workpiece, thereby affecting the glue flow rate and coating amount, resulting in uneven glue application.

[0005] This utility model is implemented as follows: an auxiliary component for a fluid dispensing machine includes a dispensing machine, a guide rail, and a worktable. The guide rail is fixedly connected to the top of the dispensing machine, and the worktable is slidably connected to the top of the guide rail. Placement boxes are fixedly connected to the left and right sides of the bottom of the worktable. The placement boxes have cavities inside, and a driving component is installed inside the cavity.

[0020] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 4As shown in the figure, an auxiliary component for a fluid dispensing machine provided in this embodiment of the utility model includes a dispensing machine 1, a guide rail 2 and a worktable 3. The guide rail 2 is fixedly connected to the top of the dispensing machine 1, and the worktable 3 is slidably connected to the top of the guide rail 2. Placement boxes 4 are fixedly connected to the left and right sides of the bottom of the worktable 3. A cavity 5 is opened inside the placement box 4. A drive component 6 is arranged inside the cavity 5. A clamping component 7 is arranged inside the cavity 5 to cooperate with the drive component 6, and the clamping component 7 extends to the top of the worktable 3.

[0023] refer to Figure 4 The drive assembly 6 includes a double-ended lead screw 601, a first pulley 602, a motor 603, a second pulley 604, and a linkage belt 605. The double-ended lead screw 601 is rotatably connected to the inside of the cavity 5. The first pulley 602 is rotatably connected to the front side of the placement box 4, and the rear side of the first pulley 602 is fixedly connected to the front side of the double-ended lead screw 601. The motor 603 is fixedly connected to the top of the dispensing machine 1. The second pulley 604 is fixedly connected to the output end of the motor 603. The linkage belt 605 is sleeved on the surface of the first pulley 602 and the second pulley 604.

[0024] Using the above solution: by setting the driving component 6, the pressing component 7 can be moved, and then the workpiece that needs to be glued can be pressed by the pressing component 7.

[0025] refer to Figure 4 The clamping assembly 7 includes a moving block 701, a base block 702, an L-shaped column 703, an electric cylinder 704, and a pressing block 705. The moving block 701 is threaded to the surface of the double-ended lead screw 601. The base block 702 is fixedly connected to the top of the moving block 701 and slidably connected to the top of the placement box 4. The L-shaped column 703 is fixedly connected to the top of the base block 702 and faces the worktable 3. The electric cylinder 704 is fixedly connected to the bottom of the L-shaped column 703. The pressing block 705 is fixedly connected to the output end of the electric cylinder 704.

[0026] The above solution involves setting up a clamping component 7 to clamp the dispensing workpiece, preventing it from moving during dispensing.

[0027] refer to Figure 4 A tripod 8 is fixedly connected to the top of the base block 702, and the other side of the tripod 8 is fixedly connected to the surface of the L-post 703.

[0028] By adopting the above solution, the stability of the connection between the L-post 703 and the base block 702 can be improved by setting the tripod 8, thus preventing it from tilting.

[0029] refer to Figure 4 The 705 pressure block is made of rubber.

[0030] The above solution is adopted: by setting a rubber pressure block 705, damage to the workpiece is avoided after the pressure block 705 comes into contact with the workpiece.

[0031] refer to Figure 2 and Figure 4 There are two clamping components 7, which are threaded to both sides of the double-ended lead screw 601.

[0032] The above solution, by setting four clamping components 7, can stably clamp the workpiece and prevent it from moving during dispensing.

[0033] refer to Figure 4 The two threads of the double-ended lead screw 601 are set in opposite directions.

[0034] Using the above solution: by setting a double-ended lead screw 601, the two clamping components 7 can be moved toward each other or away from each other according to the opposite direction of their surface threads.

[0035] The working principle of this utility model:

[0036] In use, the workpiece to be glued is placed on the worktable 3, and then the motor 603 is started. The motor 603 drives the second pulley 604 to rotate, and then the second pulley 604 drives the first pulley 602 to rotate through the linkage belt 605. At this time, the first pulley 602 drives the double-ended lead screw 601 to rotate. After the double-ended lead screw 601 rotates, it can drive the two threaded moving blocks 701 to move. When the moving blocks 701 move, they drive the base block 702 to move. When the base block 702 moves, it drives the L-column 703 and the electric cylinder 704 to move. Then the electric cylinder 704 can be started. The electric cylinder 704 drives the pressure block 705 to move down, and then the pressure block 705 can press the workpiece tightly to prevent the workpiece from moving.

[0037] In summary, the auxiliary components for this fluid dispensing machine, through the coordinated use of the dispensing machine 1, guide rail 2, worktable 3, placement box 4, cavity 5, drive assembly 6, clamping assembly 7, and tripod 8, solve the problems of workpiece movement or displacement during dispensing without clamping and positioning, resulting in inaccurate glue application to the predetermined position. Furthermore, the instability of the workpiece may cause changes in the distance between the dispensing head and the workpiece, thus affecting the glue flow rate and coating amount, and causing uneven glue application.
