Description

Technical Field

[0001] The present disclosure relates to the field of automation equipment, and in particular to a device for injecting a viscous fluid into a blind hole. Background Art

[0002] Conductive adhesive coating and dispensing technology are widely used in many industrial fields, especially in automobile manufacturing, semiconductor manufacturing and sensor manufacturing. These technologies are mainly used to apply glue-like substances to specific locations on the surface or inside of the product to ensure the stability and reliability of the product in terms of electronic, electrical and mechanical properties. Conductive adhesive is mainly used for conductive connection of electronic components and has excellent conductivity and adhesion properties; dispensing technology is used to accurately control the amount of glue and the coating position, and is often used in products that require precision processing, such as semiconductor chip packaging and sensor component manufacturing.

[0003] At present, glue dispensing is usually achieved through manual operation. The traditional glue dispensing process relies on the operator holding a glue gun, inserting the needle into the hole of the product and manually controlling the injection depth of the glue. This method can meet the needs in some simple and small-batch production, but in modern manufacturing that requires high precision and high efficiency, manual glue dispensing has many limitations. Manual operation is not only time-consuming and labor-intensive, but also easily affected by the operator's skill level, resulting in unstable coating quality.

[0004] More specifically, due to the manual control of the needle insertion depth and glue amount, problems such as position offset and uneven glue amount are prone to occur, resulting in poor coating accuracy and the inability to ensure product consistency. Manual operation requires alignment and coating one by one, and each operation takes a long time, which cannot meet the needs of large-scale production and has low production efficiency. The quality of manual operation is highly dependent on the proficiency and attention of the operator, and is easily affected by human factors, resulting in unstable product quality. In summary, the manual dispensing method of the prior art has significant deficiencies in modern manufacturing, and there is an urgent need for an automated dispensing solution that can improve accuracy, efficiency and stability. Utility Model Content

[0008] A conveyor belt, the conveyor belt is used to convey the product having the blind hole;

[0009] a lifting member configured to move in a vertical direction so as to lift the product from the conveyor belt to an injection position by a supporting action and to lower the product from the injection position back onto the conveyor belt by a supporting action; and

[0010] A nozzle is provided for releasing the viscous fluid into a blind hole of the product raised to the injection position.

[0011] The disclosed embodiment provides a device for injecting a viscous fluid into a blind hole, and the combination of a conveyor belt and a lifting component realizes automated assembly line production. The injection process can be automatically completed by simply placing the product on the conveyor belt. When the conveyor belt transports the product, the lifting component lifts it, and the nozzle accurately injects into the blind hole, thereby realizing efficient and continuous production and greatly improving production efficiency. The nozzle can accurately find the blind hole and inject it, thanks to the vertical movement of the lifting component to ensure that the nozzle is aligned with the blind hole. This design simplifies the alignment process, ensures the accuracy and consistency of the injection, and avoids injection failure or product defects caused by position offset. The lifting component plays a key role in the process of the product being detached from and put back on the conveyor belt. The product is lifted and lowered back through simple vertical reciprocating motion, without the need for complex clamping or adsorption operations. This design simplifies the mechanical structure, reduces production and maintenance costs, makes the operation more stable and reliable, reduces the equipment failure rate, and further improves production efficiency and product quality.

[0018] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In the prior art, due to the manual control of the needle insertion depth and glue amount, problems such as position offset and uneven glue amount are prone to occur, resulting in poor coating accuracy and the inability to ensure product consistency. Manual operation requires alignment and coating one by one, and each operation takes a long time, which cannot meet the needs of large-scale production and has low production efficiency. In addition, the quality of manual operation is highly dependent on the proficiency and attention of the operator, and is easily affected by human factors, resulting in unstable product quality. In summary, the manual dispensing method of the prior art has significant deficiencies in the modern manufacturing industry, and there is an urgent need for an automated dispensing solution that can improve accuracy, efficiency and stability.

[0020] In order to overcome the above-mentioned deficiencies in the prior art, the present disclosure proposes an automated device, which effectively solves the problems of poor precision, low efficiency and unstable quality in the prior art, significantly improves the degree of automation and production efficiency of the dispensing process, and is suitable for large-scale industrial production.

[0021] See also Figure 1 The embodiment of the present disclosure provides a device 1 for injecting a viscous fluid F into a blind hole B, specifically, Figure 2 The viscous fluid F and the blind hole B are shown in FIG. The viscous fluid F can be, for example, a conductive adhesive used in the packaging and assembly process of electronic components. Figure 3 As more clearly shown in FIG. 1 , the device 1 may include:

[0022] A conveyor belt 10, the conveyor belt 10 is used to convey a product P having a blind hole B;

[0023] A lifting member 20, which is configured to move in the vertical direction so as to lift the product P from the conveyor belt 10 to the injection position by supporting action and to lower the product P from the injection position back to the conveyor belt 10 by supporting action. The lifting member 20 here can be driven by a cylinder, for example; and

[0024] A nozzle 30 is provided for releasing the viscous fluid F into the blind hole B of the product P which is raised to the injection position.

[0025] For the device 1 according to the embodiment of the present disclosure: First, the combination of the conveyor belt 10 and the lifting component 20 realizes automated assembly line production. The conveyor belt 10 can continuously convey the product P with the blind hole B. The entire injection process can be automatically completed by simply placing the product P on the conveyor belt 10. Specifically, in the process of the conveyor belt 10 transporting the product P, the lifting component 20 lifts the product P, and the nozzle 30 then accurately injects the viscous fluid F into the blind hole B. In this way, the entire device 1 can achieve efficient and continuous assembly line production, greatly improving production efficiency; secondly, the nozzle 30 can accurately find the blind hole B and inject it, which is mainly due to the design of the lifting component 20. The lifting component 20 moves in the vertical direction to lift the product P from the conveyor belt 10, so that it is separated from the conveyance of the conveyor belt 10, ensuring that the nozzle 30 can freely adjust its position to align with the blind hole B. This design not only simplifies the alignment of the nozzle 30 with the blind hole B, but also greatly improves the production efficiency. process, and ensures the accuracy and consistency of each injection, avoiding injection failure or defective product P due to position deviation; finally, the lifting component 20 plays a key role in the process of product P being detached from and put back into the conveyor belt 10. Specifically, the lifting component 20 can complete the lifting and lowering of product P through simple vertical reciprocating motion. This process does not require complex operations such as clamping or adsorption. Only one component is needed to achieve support and movement, which greatly simplifies the mechanical structure and reduces production costs and maintenance difficulties. At the same time, this design makes the operation more stable and reliable, reduces equipment failure rate, and further improves production efficiency and product P quality.

[0026] In a specific embodiment of the present disclosure, see Figure 3 , the device 1 may further include:

[0027] a vision unit 40 for identifying the position of the blind hole B of the product P raised to the injection position; and

[0028] The control unit 50 is used to guide the nozzle 30 to extend into the blind hole B according to the position recognized by the vision unit 40.

[0029] Through the combination of the visual unit 40 and the control unit 50, high-precision positioning and injection of the blind hole B can be achieved. The visual unit 40 monitors and identifies the position of each blind hole B of each product P in real time to ensure that the nozzle 30 is injected at the optimal position. The control unit 50 accurately controls the movement path and injection depth of the nozzle 30 according to the data provided by the visual unit 40, thereby ensuring the accuracy and consistency of each injection. In this way, not only the coating accuracy of the product P is improved, but also the consistency and quality stability of the product P are greatly improved. In addition, for products P with one or more blind holes B, the position of each blind hole B is identified by the visual unit 40, and the control unit 50 guides the nozzle 30 to perform multi-hole injection in turn. In this way, no matter how the number and distribution of blind holes B on the product P change, the device 1 can efficiently complete the injection task, adapt to complex production needs, and improve the versatility and flexibility of the equipment.

[0030] In a specific embodiment of the present disclosure, see Figure 2 Combined with Figure 3 The control unit 50 is also used to adjust the distance between the opening 31 of the nozzle 30 and the bottom BU of the blind hole B before the nozzle 30 releases the viscous fluid F, so that the viscous fluid F leaving the opening 31 will not block the air at the bottom BU of the blind hole B.

[0031] The technical solution is specially designed that the control unit 50 adjusts the distance between the opening of the nozzle 30 and the bottom of the blind hole B before the nozzle 30 releases the viscous fluid F, so as to ensure that the viscous fluid F will not block the air at the bottom of the blind hole B during the injection process. In this way, the viscous fluid F leaving the opening of the nozzle 30 can smoothly fill the bottom of the blind hole B without forming bubbles, thereby ensuring a high level of injection quality. This not only solves the bubble problem, but also further improves the performance and reliability of the product P.

[0032] In a specific embodiment of the present disclosure, see Figure 2 Combined with Figure 3 The control unit 50 is also used to drive the nozzle 30 to move upward during the process of the nozzle 30 releasing the viscous fluid F, and control the moving distance and the time of moving the distance so that the nozzle 30 will not be immersed in the viscous fluid F released into the blind hole B.

[0033] In this way, when the nozzle 30 leaves the blind hole B, the injected viscous fluid F will not be carried along, thereby preventing the nozzle 30 from taking away the viscous fluid F. With this design, the viscous fluid F will not spill, ensuring the cleanliness and safety of the working area. At the same time, the viscous fluid F in the blind hole B can be fully injected into place, improving the overall quality and reliability of the injection.

[0034] In a specific embodiment of the present disclosure, see Figure 4 Combined with Figure 3 The device 1 may further include a calibration platform 60 having a horizontal plane 61 , and the control unit 50 may be configured to make the nozzle 30 contact the horizontal plane 61 to calibrate the vertical position of the nozzle 30 .

[0035] The design of the calibration table 60 makes the calibration process of the newly replaced nozzle 30 intuitive and easy to operate. Specifically, the calibration table 60 is equipped with a horizontal plane 61, and the control unit 50 can detect the position of the nozzle 30 when it contacts the horizontal plane 61. Such a design simplifies the calibration steps, and the operator can complete the calibration without complicated adjustments when replacing the nozzle 30. Moreover, the calibration table 60 provides a stable and accurate reference surface. When the nozzle 30 contacts the horizontal plane 61, the control unit 50 can accurately record the vertical position at this time as the reference vertical position, which can ensure the position accuracy of the nozzle 30 in actual operation, reduce errors, and improve the overall reliability of the equipment. In addition, the use of mechanical calibration has lower manufacturing and maintenance costs than electronic or optical calibration equipment. The calibration table 60 has a simple structure, and the materials are easily available and inexpensive, which can significantly reduce production costs. In addition, simple mechanical calibration also reduces the failure rate and maintenance costs of the equipment.

[0036] In a specific embodiment of the present disclosure, see Figure 5 , the device 1 may further include:

[0037] A plurality of trays 70, each tray 70 of the plurality of trays 70 is used for carrying a product P;

[0038] a material clamp 80 configured to clamp the plurality of trays 70 each carrying the product P therein, for example, a clamping groove may be formed in the material clamp, the clamping groove being used to clamp the trays 70; and

[0039] The material pulling mechanism 90 is used to transfer the multiple trays 70 clamped in the material clamp 80 to the conveyor belt 10 one by one, and the lifting component 20 applies a supporting effect on the tray 70. The material pulling mechanism 90 here can also be driven by a cylinder, for example.

[0040] The multiple trays 70 in the device 1 are used to carry the product P, and each tray 70 is clamped by the material clamp 80. The material pulling mechanism 90 is responsible for transferring the multiple trays 70 clamped in the material clamp 80 to the conveyor belt 10 one by one. This process realizes automatic and uninterrupted placement, significantly improves production efficiency, and avoids manual operation. The product P is placed on the conveyor belt 10 by automated equipment instead of manual labor, which reduces the dependence on manual operation, reduces labor intensity, and reduces errors and delays that may be caused by manual operation. Since the tray 70 can be automatically and continuously transferred to the conveyor belt 10 by the material pulling mechanism 90, the entire product P placement process becomes smoother and more efficient, the production line runs more smoothly, and the overall production efficiency is significantly improved. The automated equipment ensures that the product P on each tray 70 is placed on the conveyor belt 10 in the same position and manner, thereby ensuring the accuracy of product P placement and the consistency of production quality, and reducing position deviations and quality problems caused by manual operation.

[0041] In a specific embodiment of the present disclosure, see Figure 5 The multiple trays 70 clamped in the material clamp 80 can be arranged vertically, the material pulling mechanism 90 can be moved horizontally, and the device 1 can also include a material tower mechanism 100, which is used to drive the material clamp 80 to move vertically, so that the material pulling mechanism 90 can transfer each tray 70.

[0042] In this way, the material tower mechanism 100 can drive the material clamp 80 to move vertically, and the material pulling mechanism 90 can move horizontally. This two-way movement design makes the system highly flexible and adaptable, and can adapt to the placement requirements of products P of different sizes and types, further improving the versatility of the production line. In addition, the production line can realize an efficient, continuous, and automated product P placement process, significantly improving production efficiency and product P quality, while reducing manual operations and related costs.

[0043] In a specific embodiment of the present disclosure, the visual unit 40 is also used to judge the injection quality after the viscous fluid F is injected into the blind hole B. Figure 1 and Figure 4 , the device 1 may further include:

[0044] A material discharge chute 110, wherein the material discharge chute 110 is configured so that the tray 70 placed on the material discharge chute 110 automatically slides away from the device 1;

[0045] The suction cup 120 is used to transfer the product P judged by the visual unit 40 as having unqualified injection quality from the conveyor belt 10 to the unloading chute 110.

[0046] Through the visual unit 40, after the viscous fluid F is injected into the blind hole B, the injection quality can be automatically judged. This automated detection process ensures that the injection quality of each product P meets the requirements, reduces the errors and delays of human judgment, and improves the overall quality control level of the production line. For the product P judged by the visual unit 40 as having unqualified injection quality, it is transferred from the conveyor belt 10 to the unloading chute 110 through the suction cup 120. This process realizes the automatic sorting and removal of unqualified products P, avoids unqualified products P from entering the subsequent process or market, and further improves the quality of the final product P. The design of the unloading chute 110 enables the tray 70 placed on it to automatically slide away from the device 1, realizing the automatic transfer and processing of unqualified products P. This automated process reduces manual intervention, ensures the continuity and efficient operation of the production line, and significantly improves the overall production efficiency. Through visual inspection and automatic sorting, the entire process does not require manual intervention, reduces dependence on manual operation, reduces labor intensity and labor costs, and reduces errors and instability caused by manual operation.

[0047] In a specific embodiment of the present disclosure, see Figure 1 The device 1 may further include three mutually perpendicular guide rails 130 , wherein the first guide rail 131 is fixedly arranged, the second guide rail 132 is configured to move along the first guide rail 131 , the third guide rail 133 is configured to move along the second guide rail 132 , and the nozzle 30 may be arranged on the third guide rail 133 .

[0048] The device 1 includes three mutually perpendicular guide rails 130, so that the nozzle 30 can move freely in three-dimensional space. Specifically, since the first guide rail 131 is fixedly arranged, the second guide rail 132 can move along the first guide rail 131, and the third guide rail 133 can move along the second guide rail 132, so that the nozzle 30 can cover the entire working area, thereby achieving accurate positioning of any position in space. Through the coordinated movement of the three guide rails, the nozzle 30 can be quickly and accurately moved to the target position, greatly improving work efficiency and operation accuracy. Through the automated guide rail system, the need for manual intervention is reduced for the movement of the nozzle 30.

[0049] In a specific example according to the present disclosure, see Figure 6 The device 1 further comprises a nozzle positioning fixture 190, which is formed with a hole which is not shown in the drawings but can be understood, and the hole is configured to limit the freedom of the nozzle 30 inserted into the hole in the horizontal plane.

[0050] The nozzle positioning fixture 190 can effectively limit the freedom of the nozzle 30 in the horizontal plane, which means that the nozzle 30 can maintain a stable position during use, avoiding inaccurate release due to position deviation, thereby improving operation accuracy and product quality.

[0051] In a specific example according to the present disclosure, the aperture of the blind hole B can be less than 1.5 mm. When operating at a very small aperture, consistency and stability of operation are crucial. The fine control and high-precision operation of the device 1 can ensure the consistent injection quality of each blind hole B, reduce the defective rate and rework rate, and thus improve the overall product P quality. High-precision operations at small apertures are difficult and error-prone to manual operation. Through the application of automated equipment, the reliance on manual operation is reduced, the difficulty of operation and labor intensity are reduced, and the work efficiency and operation accuracy are improved.

[0052] See also Figure 1 For the device 1 according to the embodiment of the present disclosure, in addition to the components described above, it can also include a cabinet 140, a computer 150, a table panel 160, a material tower protective shell 170, a mounting bracket 180, etc.

[0053] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
