Description

Technical Field

[0001] This utility model relates to the technical field of high-speed dispensing equipment, and in particular to a valve body material box mechanism. Background Technology

[0002] High-speed dispensing equipment is widely used in the electronic packaging, lighting, and energy industries. With technological advancements, new requirements have been placed on the dispensing performance of high-speed dispensing equipment. Among these requirements, the dispensing valve, as the core component of high-speed dispensing equipment, directly determines the overall dispensing accuracy.

[0003] Currently, some high-speed dispensing equipment uses non-contact jet dispensing valves. This type of valve enables high-speed dispensing through non-contact jet technology. It is powered by gas and features precise dispensing, a wide applicable fluid viscosity range, and easy cleaning. However, after prolonged use, the dispensing valve needs to be removed from the high-speed dispensing equipment and moved outside for cleaning. To improve the ease of disassembly and assembly, the inventors have developed an automatic valve replacement device. This device replaces the dispensing valve on the high-speed dispensing equipment by gripping it, reducing labor costs and optimizing the overall automation level of the equipment.

[0004] However, in the process of replacing the dispensing valve in the above-mentioned device, the existing technology still lacks a solution for loading and unloading the dispensing valve, which makes it difficult for the valve body to achieve efficient loading and unloading inside and outside the equipment. Therefore, a solution that can meet the high-speed loading and unloading of the dispensing valve is provided here.

[0005] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Utility Model Content

Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments.

When a component is considered to be "set" on another component, it can be directly set on the other component or there may be a component that is centrally positioned therein.

Therefore, they should not be construed as limitations of this utility model.

[0050] Reference Figure 1This invention demonstrates a dispensing valve, which includes a valve body with an L-shaped outline and a quick-change disc for quick valve replacement. The dispensing valve requires a robotic arm for loading and unloading. Because the valve's shape is not conventionally symmetrical, transferring new and old valves presents challenges. Therefore, this embodiment provides a valve body material box mechanism to solve the dispensing valve loading and unloading problem. The following description, in conjunction with the attached... Figure 1-6 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0051] Please refer to Figure 2 This utility model provides a valve body material box mechanism, including a valve body support frame 1, a first valve body placement seat 2, a second valve body placement seat 3, and a valve body limiting component 4.

[0052] The valve body support frame 1 has a first platform 11 and a second platform 12, which provides support for the first valve body placement seat 2 and the second valve body placement seat 3. Specifically, the valve body support frame 1 provided in this embodiment includes a frame and support plates. The frame is vertically arranged, and there are two support plates. The two support plates are fixedly installed on the top and bottom of the frame, thus forming a three-dimensional frame structure with good structural stability. In addition, the two support plates form the first platform 11 and the second platform 12, respectively. Here, the support plate located above is defined as the first platform 11, and the support plate located below is defined as the second platform 12.

[0053] Meanwhile, in this embodiment, the first valve body placement seat 2 and the second valve body placement seat 3 are elongated block structures. The top of the first valve body placement seat 2 and the second valve body placement seat 3 are respectively provided with placement platforms 1001 for placing the valve body. Furthermore, an abutment plane 1002 is provided at the bottom of the dispensing valve. The abutment plane 1002 and the placement platform 1001 abut against each other in the horizontal direction. At this time, under the interaction of the abutment plane 1002 and the placement platform 1001, the dispensing valve can be placed on the top of the first valve body placement seat 2 or the second valve body placement seat 3.

[0054] Optionally, the new dispensing valve can be placed in the first valve body placement seat 2, and the old dispensing valve can be placed in the second valve body placement seat 3. Alternatively, the new dispensing valve can be placed in the second valve body placement seat 3, and the old dispensing valve can be placed in the first valve body placement seat 2. The specific placement of the dispensing valve is not limited here. In this embodiment, the new dispensing valve is placed in the first valve body placement seat 2 and the old dispensing valve is placed in the second valve body placement seat 3 as an example.

[0055] In addition, the valve body limiting component 4 is set on the placement platform 1001. The valve body limiting is used to lock and limit the dispensing valve, thereby improving the stability of the dispensing valve on the placement platform 1001 and providing a basis for automatic replacement of the dispensing valve.

[0056] By adopting the above technical solution, the first valve body placement seat 2 and the second valve body placement seat 3 can realize the classified placement of dispensing valves. At the same workstation, they can meet the functional requirements of replacing new and old dispensing valves at the same time. Furthermore, under the action of the valve body limiting component 4, the dispensing valves can be stably placed, and the problem of difficult loading and unloading of dispensing valves is solved.

[0057] Reference Figure 2 and Figure 3 To achieve the limiting and reinforcement of the dispensing valve, the valve body limiting component 4 includes two valve body baffles arranged opposite each other, forming a valve body positioning gap between the valve body baffles. The valve body positioning gap is used for the valve body to be inserted. When the valve body is inserted into the valve body positioning gap, the two valve body baffles abut against the opposite sides of the valve body respectively.

[0058] It needs to be explained that, in combination Figure 1 In order to enable the dispensing valve to be fitted into the positioning gap, limiting bosses 1003 are provided on opposite sides of the bottom of the dispensing valve. By embedding the limiting bosses 1003 into the positioning gap of the valve body, a vertical limiting effect can be achieved to prevent the dispensing valve from being loosened from the placement platform 1001.

[0059] Specifically, refer to Figure 3 To achieve the aforementioned limiting effect, the valve body baffle provided in this embodiment includes a vertical extension section 41 and a horizontal extension section 42. The bottom side of the vertical extension section 41 is connected to the placement platform 1001. At the same time, the horizontal extension section 42 is connected to the top side of the vertical extension section 41 and extends horizontally into the valve body positioning gap. At this time, the valve body baffle is equivalent to forming an inverted L-shaped limiting structure. By embedding the limiting boss 1003 on the dispensing valve into the valve body positioning gap, the limiting boss 1003 and the horizontal extension section 42 abut against each other in the vertical direction to achieve a firm limiting support effect.

[0060] It is understandable that in other embodiments, the positioning function of the dispensing valve can also be achieved by magnetic attraction. For example, a permanent magnet can be installed on the first valve body placement seat 2 or the second valve body placement seat 3. The permanent magnet can generate magnetic attraction force, thereby magnetically positioning the dispensing valve on the platform 1001. This embodiment can also improve the placement stability of the dispensing valve. Regardless of the specific solution adopted, any structure that can provide a limiting function for the dispensing valve can be tried, and all should be included in the same interpretation scope of the valve body limiting component 4.

[0061] Referring to the figure, in order to facilitate the robot arm to pick up and put down the dispensing valve, a valve body inlet 5 is provided at one end of the valve body baffle. The valve body inlet 5 can form an open space on one side of the valve body limiting component 4, so that the robot arm can freely enter and exit to the first valve body placement seat 2 or the second valve body placement seat 3, which is convenient for picking up and putting down the dispensing valve.

[0062] Furthermore, referring to Figure 4 The valve body baffle extends along the length of the first valve body placement seat 2 or the second valve body placement seat 3, thus widening the limiting space. Combined with the first valve body placement seat 2 and the second valve body placement seat 3, which have long side profiles, multiple dispensing valves can be placed on the first valve body placement seat 2 or the second valve body placement seat 3 at the same time.

[0063] However, if multiple dispensing valves are placed on the placement platform 1001, the dispensing valves may detach at both ends along the length of the placement platform 1001. This position is defined as the side end of the placement platform 1001. Based on this, to prevent the dispensing valves from detaching at the side end of the placement platform 1001, the valve body limiting assembly 4 also includes a valve body anti-detachment block 43. In this embodiment, the valve body anti-detachment block 43 can be fixed on the valve body support 1, the first valve body placement seat 2, or the second valve body placement seat 3. The specific setting position of the valve body anti-detachment block 43 is not limited here. At this time, the valve body anti-detachment block 43 blocks the side end of the placement platform 1001, thereby achieving a limiting effect. The dispensing valves are not easy to detach from the first valve body placement seat 2 or the second valve body placement seat 3, and the placement of the dispensing valves is more stable.

[0064] Furthermore, since the dispensing valve needs to pass through the valve body inlet 5 when being picked up or placed, and the valve body inlet 5 is open at this time, there is a possibility that the dispensing valve may tip over or shift during the picking and placing process. Based on this, the valve body limiting assembly 4 also includes a side pressure cylinder 44 and a side pressure block 45. The side pressure cylinder 44 is fixedly installed on the valve body support 1 and is adjacent to the positioning gap. Specifically, the output shaft of the side pressure cylinder 44 is horizontally set and faces the valve body inlet 5. The side pressure block 45 is fixedly connected to the side pressure cylinder 44. The side pressure cylinder 44 is used to drive the side pressure block 45 to press the dispensing valve, thereby achieving initial positioning of the dispensing valve, so that the dispensing valve is not easily tilted or shifted before picking and placing, and ensuring that the picking and placing of the valve body can be carried out smoothly.

[0065] Reference Figure 5 When multiple dispensing valves are placed on the first valve body placement seat 2 or the second valve body placement seat 3, the position of the valve body needs to be arranged to reduce the problem of excess dispensing valves occupying the valve body inlet 5, so as to ensure that the robot can smoothly pick up and put the dispensing valve at the dispensing valve inlet.

[0066] Specifically, it also includes a valve body adjustment assembly 6, which is respectively disposed on the first valve body placement seat 2 and the second valve body placement seat 3. The valve body adjustment assembly 6 includes a valve body belt module 61 and a drive module 62.

[0067] The valve body belt module 61 abuts against the dispensing valve. In this embodiment, the valve body belt module 61 mainly includes a drive wheel 611, a driven wheel 612, and a belt 613. The drive wheel 611 and the driven wheel 612 are rotatably mounted on the first valve body placement seat 2 or the second valve body placement seat 3, respectively. The belt 613 covers the drive wheel 611 and the driven wheel 612. When the drive wheel 611 rotates, the belt 613 can rotate under the drive of the driven wheel 612. The valve body is placed on the belt 613, and the belt 613 can drive the valve body to move along the length direction of the first valve body placement seat 2 or the second valve body placement seat 3, thereby adjusting the displacement of multiple valve bodies and realizing automatic sorting of valve bodies. This ensures that the valve body placement inlet 5 is empty, which is conducive to the picking and placing of valve bodies.

[0068] At the same time, refer to Figure 6 The drive module 62 is connected to the valve body belt module 61 and is used to drive the valve body belt module 61 to operate. Specifically, the drive module 62 adopts a motor component, which is fixedly installed on the first valve body mounting seat 2 or the second valve body mounting seat 3, and the output shaft of the drive module 62 is connected to the drive wheel 611. By driving the drive wheel 611 to rotate, the valve body belt module 61 is operated.

[0069] By adopting the above configuration, the drive module 62 can provide stable power output. During the operation of the valve body belt module 61, it can drive the valve body to move and adjust along the length direction of the first valve body placement seat 2 or the length direction of the second valve body placement seat 3, so as to achieve orderly arrangement among multiple dispensing valves, and at the same time, it is also beneficial for the robot to pick up and put down the dispensing valves.

[0070] Furthermore, the valve body belt modules 61 are configured as two sets that are parallel to each other and spaced apart, and the drive module 62 is connected to both sets of valve body belt modules 61 simultaneously. Specifically, the two sets of valve body belt modules 61 are arranged in a mirror-symmetrical manner, and the output shaft of the motor component is connected to the two drive pulleys 611 respectively, so that the drive module 62 can drive the two sets of valve body belt modules 61 to operate synchronously at the same time. At the same time, the two sets of valve body belt modules 61 are in contact with the opposite sides of the abutment plane 1002, thereby providing a balanced driving force for the valve body. The valve body is not prone to torsion and uneven load during displacement and rotation, and the valve body rotation is smooth and stable.

[0071] Furthermore, the first dispensing valve placement seat is slidably disposed on the first platform 11, and / or the second dispensing valve placement seat is slidably disposed on the second platform 12. When all new dispensing valves are removed from the first valve body placement seat 2, or when the second valve body placement seat 3 is full of old dispensing valves, it is necessary to periodically replace the old dispensing valves with new ones. Therefore, by slidably installing the first valve body placement seat 2 and the second valve body placement seat 3, they can be pulled outwards from the equipment, facilitating manual replacement of the dispensing valves and making the operation convenient and quick.

[0072] It is understood that in this embodiment, the first valve body placement seat 2 is slidably disposed on the first platform 11, and the second valve body placement seat 3 is slidably disposed on the second platform 12. In other embodiments, the first valve body placement seat 2 or the second valve body placement seat 3 may be configured as slidable. The specific configuration of the first valve body placement seat 2 and the second valve body placement seat 3 is not limited here.

[0073] Optionally, the sliding assembly method of the first valve body placement seat 2 and the second valve body placement seat 3 is the same under normal circumstances. In order to realize the sliding function of the first valve body placement seat 2 and the second valve body placement seat 3, taking the first valve body placement seat 2 as an example, a slide rail 7 can be fixedly installed at the first platform 11, and a slider that slides with the slide rail 7 is provided at the bottom of the first valve body placement seat 2. Under the action of the slide rail 7 and the slider, the first valve body placement seat 2 is slidably set on the first platform 11. Correspondingly, the assembly method of the second valve body placement seat 3 on the second platform 12 adopts the same method, which will not be described in detail here.

[0074] Furthermore, continue to refer to Figure 6 When the first valve body placement seat 2 and the second valve body placement seat 3 are configured to be slidable, there may be a positional offset, which will affect the positioning accuracy of the structure and cause the gripping action of the robot to fail. Based on this, in order to improve the positioning accuracy of the first valve body placement seat 2 and the second valve body placement seat 3, a wedge-shaped positioning block 8 is provided on the valve body support frame 1; and a wedge-shaped extension 9 is provided on the first valve body placement seat 2 and / or the second valve body placement seat 3 to engage and position with the wedge-shaped positioning block 8.

[0075] With the cooperation of the wedge-shaped positioning block 8 and the wedge-shaped extension 9, the excessive displacement of the first valve body placement seat 2 or the second valve body placement seat 3 can be restricted, thereby positioning the first valve body placement seat 2 or the second valve body placement seat 3 and ensuring the accuracy of dispensing valve placement.

[0076] In this embodiment, the first platform 11 and the second platform 12 are respectively provided with wedge-shaped positioning blocks 8, and the first valve body placement seat 2 and the second valve body placement seat 3 are respectively provided with wedge-shaped extensions 9. The two wedge-shaped positioning blocks 8 and the two wedge-shaped extensions 9 are paired up in pairs, so that the first valve body placement seat 2 and the second valve body placement seat 3 are positioned in the sliding state, and the overall accuracy of the structure is optimized and improved.

[0077] Furthermore, to prevent the first valve body placement seat 2 and the second valve body placement seat 3 from shaking when the dispensing valve is picked up or put down, the valve body support frame 1 is provided with an elastic pin 10. The elastic pin 10 is used to abut and limit the first valve body placement seat 2 or the second valve body placement seat 3 to prevent the first valve body placement seat 2 and the second valve body placement seat 3 from slipping off on their own.

[0078] Specifically, the resilient pin 10 typically includes a pin shaft and a spring element. The pin shaft is slidably mounted on the first platform 11 or the second platform 12, and one end of the pin shaft faces the location of the first valve body mounting seat 2 or the second valve body mounting seat 3. At the same time, both ends of the spring element are connected to the pin shaft and the first platform 11, or both ends of the spring element are connected to the pin shaft and the second platform 12. The spring element provides elastic force to the pin shaft, enabling the pin shaft to extend toward the first valve body mounting seat 2 and the second valve body mounting seat 3.

[0079] At this time, a limiting hole that engages with the pin can be provided on the first valve body placement seat 2 or the second valve body placement seat to provide a locking function for the first valve body placement seat 2 and the second valve body placement seat 3. When the spring pin and the limiting hole are in the locking condition, the displacement of the first valve body placement seat 2 and the second valve body placement seat 3 can be restricted, thereby ensuring that the first valve body placement seat 2 and the second valve body placement seat 3 will not wobble or shift during operation.

[0080] Alternatively, the pin can be directly abutted against the side of the first valve body mounting seat 2 or the second valve body mounting seat 3, which can also achieve the limiting function and prevent the first valve body mounting seat 2 and the second valve body mounting seat 3 from shaking or shifting during operation.

[0081] Here, no restrictions are placed on the specific limiting method of the spring pin. As long as the abutment limiting method is adopted, it should be included in the scope of interpretation of this solution.

[0082] The valve body material box mechanism provided in this application embodiment has the following beneficial effects:

[0083] 1. The dual-layer placement structure can simultaneously accommodate both new and old dispensing valves, enabling the loading and unloading of new and old dispensing valves at the same workstation, thus solving the problem of low efficiency in valve loading and unloading.

[0084] 2. The valve body limiting component 4 can restrict the vertical movement of the dispensing valve, making the dispensing valve more stable when placed.

[0085] 3. It can accommodate multiple dispensing valves simultaneously, which helps meet the long-term replacement needs of high-speed dispensing equipment.

[0086] Therefore, the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
