Description

Technical Field

[0002] Precision dispensing technology is widely used in automated production lines for various electronic products, and dispensing valves are the core equipment for achieving this precision. Dispensing valves primarily consist of a valve body and a valve seat. The valve seat is the primary functional module for the flow, storage, and dispensing of glue. Therefore, in practice, regular disassembly and assembly of the valve seat and body are often required for maintenance, such as replacing glue or cleaning and maintaining the glue flow path.

[0003] Currently, the valve body and valve seat of dispensing valves are secured together using screws. Dispensing valves are typically located relatively low on production line equipment and very close to the flow control table, resulting in very limited space for screw removal and assembly, making disassembly of the valve seat and valve body relatively difficult.

[0065] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in this embodiment. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0066] In order to facilitate the understanding of the technical solution provided by this application, the relevant contents of the technical solution of this application are first explained below. With the advancement of science and technology, various electronic products are constantly moving towards a more sophisticated and lightweight direction. In the process of advancement, more stringent requirements are inevitably placed on the production and assembly process of the product. Precision dispensing is to use dispensing equipment to accurately apply, encapsulate, and drip glue, protective liquid, etc. to the designated position of the product, thereby making the product sticky, encapsulated, insulated, fixed, and smooth on the surface. The dispensing valve is a functional unit on the dispensing equipment used to complete the precision dispensing action. In order to achieve rapid disassembly and assembly of the valve seat part and the valve body part of the dispensing valve, so as to facilitate the replacement, disassembly, maintenance and other processing of the valve seat, the present application provides a dispensing valve, in which the valve seat part and the valve body part are relatively fixed by nesting and plugging, which can realize quick and convenient disassembly and assembly of the dispensing valve, reduce space requirements, and simplify operation, which is conducive to the promotion of the dispensing valve.

[0067] Figure 1 A cross-sectional view of a dispensing valve provided in this application, such as Figure 1 As shown, the dispensing valve comprises a main valve body and a valve seat. The main valve body includes a main valve cavity 1, a striker 2, a seal 3, and a locking mechanism 4. The valve seat comprises a valve seat body 5, a nozzle assembly 6, and a rubber cartridge 7. The rubber cartridge 7 stores rubber and delivers it to the valve seat through a flow channel, allowing the rubber to be precisely dripped into the designated location through the nozzle assembly 6.

[0068] The valve seat body 5 is provided with a guide sleeve structure 8; the main valve body cavity 1 is provided with a guide hole structure corresponding to the guide sleeve structure 8, and the striker 2 is fixed to the guide hole structure. The striker 2 on the guide hole structure is fixed to the valve seat part by correspondingly inserting and inserting the guide hole structure of the main valve body and the guide sleeve structure 8 of the valve seat part.

[0069] The present application provides corresponding guide hole structures and guide sleeve structures, so that the main valve body and the valve seat part can be precisely plugged in.

[0070] Figure 2 A schematic diagram of the structure of a dispensing valve provided in this application is shown as follows: Figure 2 As shown, the locking mechanism 4 is disposed on and connected to the main valve body cavity 1, thereby being fixedly connected to the main valve body. Specifically, the locking mechanism 4 is disposed at the lower portion of one side of the main valve body. The locking mechanism 4 is used to lock the relative position of the valve seat and the main valve body after the dispensing valve is assembled. As an alternative, the locking mechanism 4 is fixedly connected to the main valve body via screws.

[0071] The main valve body cavity 1 is fixed to the valve seat portion via a seal 3. Specifically, the seal 3 passes through the striker 2 on the guide hole structure and connects to the guide hole structure; the striker 2 on the guide hole structure is fixed to the valve seat portion by correspondingly nesting and inserting the guide hole structure of the main valve body, the seal 3, and the guide sleeve structure 8 of the valve seat portion.

[0072] In the present application, the sealing member is arranged between the main valve body cavity and the valve seat portion, which can play a sealing role and can make the main valve body cavity and the valve seat portion fixed more tightly.

[0073] Figure 3 A schematic diagram of the structure of a main valve body provided in this application is shown as follows: Figure 3 As shown, the main valve body further includes a first tongue plate structure 11 .

[0074] A first tongue plate structure 11 is disposed at the lower portion of the main valve body cavity 1; the first tongue plate structure 11 is used to retain the valve seat, thereby securing the main valve body relative to the valve seat. Alternatively, the main valve body can be hooked to the valve seat via the first tongue plate structure 11, thereby securing the main valve body relative to the valve seat.

[0075] Furthermore, if Figure 3 As shown, the main valve body further includes a first slot structure 12 .

[0076] A first retaining groove structure 12 is provided at the lower portion of the main valve body cavity 1; the first retaining groove structure 12 is used to retain the main valve body relative to the valve seat, thereby securing the main valve body relative to the valve seat. Alternatively, the main valve body can be hooked onto the valve seat via the first retaining groove structure 12, thereby securing the main valve body relative to the valve seat.

[0077] like Figure 3 As shown, a guide hole structure 9 is provided on the main valve body cavity 1, and the position of the guide hole structure 9 corresponds to the position of the guide sleeve structure 8. The guide hole structure 9 can play a positioning and guiding role when the main valve body and the valve seat are nested and plugged, so that the main valve body and the valve seat can be accurately nested and plugged, thereby being relatively fixed.

[0078] like Figure 3 As shown, the sealing member 3 passes through the striker rod 2 on the guide hole structure 9 and is fitted into place on the main valve body cavity 1 to assemble the main valve body.

[0079] Figure 4 A cross-sectional view of a main valve body cavity provided in this application, such as Figure 4 As shown, the main valve body further includes a first transition zone 13 .

[0080] The first transition zone 13 is arranged at the front end of the first tongue plate structure 11, and the first transition zone 13 is fixedly connected to the front end of the first tongue plate structure 11, that is, the first transition zone 13 and the first tongue plate structure 11 are integrally formed, so that the first tongue plate structure 11 is relatively fixed to the valve seat part through the first transition zone 13.

[0081] As an optional solution, the first transition zone 13 is a sloped transition zone, which can achieve adaptive adjustment of the longitudinal position during the relative fixation of the first tongue plate structure and the valve seat portion.

[0082] Figure 5 A schematic diagram of the structure of a locking mechanism provided in this application is shown as follows: Figure 5 As shown, the locking mechanism 4 includes a screw 41, and the locking mechanism 4 is fixedly connected to the main valve body through the screw 41. The side of the main valve body is provided with an interface corresponding to the screw 41 for fastening the locking mechanism 4 to the main valve body through the screw 41. Figure 5 The locking mechanism 4 shown is fixed by two sets of screws.

[0083] like Figure 5 As shown, the locking mechanism 4 further includes a rebound mechanism (not shown) and an elastic telescopic rod 42. As an optional solution, the rebound mechanism is a conventional rebound mechanism such as a spring or a shrapnel.

[0084] The elastic telescopic rod 42 includes a first portion 421 disposed within the locking mechanism and a second portion 422 disposed outside the locking mechanism. The first portion 421 and the second portion 422 of the elastic telescopic rod 42 are integrally formed. As an alternative, the first portion 421 of the elastic telescopic rod 42 is a cylindrical straight segment, and the first portion 422 of the elastic telescopic rod 42 is a spherical arc segment. The cylindrical straight segment first portion 421 and the spherical arc segment second portion 422 are integrally formed.

[0085] In the present application, the rebound mechanism is arranged inside the locking mechanism 4, and one side of the rebound mechanism is connected to the inside of the locking mechanism 4, and the other side is connected to the first portion 421 of the elastic telescopic rod 42. The rebound mechanism is used to control the elastic expansion and contraction of the elastic telescopic rod 42.

[0086] In the present application, during the assembly process of the dispensing valve, the valve seat part and the second part 422 of the elastic telescopic rod 42 are squeezed, so that the rebound mechanism is in a compressed state until the angle between the valve seat part and the main valve body in the horizontal direction is zero, and the elastic telescopic rod 42 is extended and reset to lock the relative position of the valve seat part and the main valve body.

[0087] In this application, a rebound mechanism is set inside the locking mechanism, and the elastic telescopic function of the elastic telescopic rod is realized by compression or extension of the rebound mechanism, thereby controlling the relative position of the locking valve seat part and the main valve body during the assembly process of the dispensing valve.

[0088] Figure 6 A schematic diagram of the structure of a valve seat portion provided in this application, such as Figure 6 As shown, the valve seat portion further includes a second tongue plate structure 51 .

[0089] A second tongue plate structure 51 is disposed above the valve seat body 5; its position corresponds to the first retaining groove structure 12 of the main valve body. The second tongue plate structure 51 is used to retain the main valve body, thereby securing the main valve body and the valve seat relative to each other. Specifically, the main valve body engages with the second tongue plate structure 51 on the valve seat via the first retaining groove structure 12, thereby securing the main valve body and the valve seat relative to each other.

[0090] Further, if Figure 6 As shown, the valve seat portion further includes a second groove structure 52 .

[0091] A second retaining groove structure 52 is provided on the upper portion of the valve seat body 5; its position corresponds to the first tongue structure 12 of the main valve body. The second retaining groove structure 52 is used to retain the main valve body, thereby securing the main valve body and the valve seat relative to each other. Specifically, the main valve body is secured relative to the valve seat by hooking the first tongue structure 12 with the second retaining groove structure 52 of the valve seat.

[0092] like Figure 6 As shown, the valve seat body 5 is provided with a guide sleeve structure 8, the position of which corresponds to the position of the guide hole structure 9. The guide hole structure 9 serves as a positioning guide when the main valve body and the valve seat are nested and plugged together, allowing the main valve body and the valve seat to be precisely nested and plugged together, thereby relatively fixed.

[0093] Figure 7 A cross-sectional view of a valve seat portion provided in this application, such as Figure 7 As shown, the valve seat portion further includes a second transition zone 53 .

[0094] The second transition zone 53 is arranged at the front end of the second tongue plate structure 51, and the second transition zone 53 is fixedly connected to the front end of the second tongue plate structure 51, that is, the second transition zone 53 and the second tongue plate structure 51 are integrally formed, so that the second tongue plate structure 51 is relatively fixed to the main valve body through the second transition zone 53.

[0095] As an optional solution, the second transition zone is a sloped transition zone, which can achieve adaptive adjustment of the longitudinal position during the relative fixation of the second tongue plate structure and the main valve body.

[0096] like Figure 6 As shown, the valve seat body 5 further includes a limiting platform structure 54 .

[0097] The limiting platform structure 54 is disposed on the upper portion of the second slot structure 52 , and the limiting platform structure 54 is fixedly connected to the upper portion of the second slot structure 52 , that is, the limiting platform structure 54 and the upper portion of the second slot structure 52 are integrally formed.

[0098] like Figure 7 As shown, the limit platform structure 54 includes a progressive lifting belt 541 and a rapid lifting transition belt 542, which are integrally formed. The limit platform structure 54 is used to prevent the locking mechanism 4 from restricting the rotation process during the relative rotation of the valve seat portion and the main valve body.

[0099] The progressive lifting belt 541 is used to lift the elastic telescopic rod 42 of the locking mechanism 4, so that the valve seat part and the main valve body are relatively fixed or separated by the progressive lifting belt 541.

[0100] The rapid lifting transition zone 542 is used to enable the elastic telescopic rod 42 to quickly extend and reset when the angle between the valve seat portion and the main valve body in the horizontal direction is zero.

[0101] As an optional solution, the progressive lifting belt 541 of the limit platform structure 54 is a gentle and long slope structure, and its function is to smoothly lift the elastic telescopic rod 42 of the locking mechanism 4 during the process of the valve seat part being rotated into the main valve body as a whole, so that it cannot hinder the rotation operation of the valve seat part.

[0102] As an optional solution, the rapid lifting transition zone 542 of the limit platform structure 54 is a steep and short small slope structure, which can ensure that the elastic telescopic rod 42 of the locking mechanism 4 is quickly and elastically reset after the valve seat part is screwed into the main valve body, thereby locking the relative position of the valve seat part and the main valve body. At this time, since the lowest point of the rapid lifting transition zone 542 is higher than the lowest point of the progressive lifting zone 541, that is, there is a height difference d between the lowest point of the progressive lifting zone 541 and the lowest point of the rapid lifting transition zone 542, it can ensure that the first part 421 of the elastic telescopic rod 42 of the locking mechanism 4 is fully in contact with the vertical surface of the limit platform structure 54, thereby forming a reliable limit for the relative rotation movement of the valve seat part; when the valve seat part needs to be removed, the elastic telescopic rod 42 of the locking mechanism 4 can be lifted to a certain height by using a suitable tool and maintained at the lifted height, and at the same time, the valve seat part can be relatively rotated (the rotation direction is opposite to the screw-in direction), so that the elastic telescopic rod 42 can be quickly lifted to the top, and the valve seat part can be smoothly rotated into place and removed. The upward lifting height is not less than the height difference d between the lowest point of the progressive lifting zone 541 and the lowest point of the rapid lifting transition zone 542 .

[0103] The present application also provides a dispensing valve assembly method. The assembly process of the dispensing valve is described below through a specific embodiment:

[0104] The striker on the guide hole structure is inserted through the guide hole structure of the main valve body and the guide sleeve structure of the valve seat at a specified angle α. As an optional solution, the specified angle α is 90 degrees, so that the center positions of the guide hole structure of the main valve body and the guide sleeve structure of the valve seat are aligned and the corresponding inserting and inserting are performed. Figure 8 A schematic diagram of a valve seat portion and a main valve body provided in this application is shown as follows: Figure 8 As shown, the guide hole structure 9 of the main valve body and the guide sleeve structure 8 of the valve seat part are at an angle of 90 degrees, that is: α = 90°. The center positions of the guide hole structure 9 of the main valve body and the guide sleeve structure 8 of the valve seat part are aligned and nested and plugged.

[0105] When the nested insertion depth reaches the specified depth, the valve seat portion is rotated in a first direction relative to the main valve body until the first tongue plate structure of the main valve body and the second slot structure of the valve seat portion are relatively fixed and the first slot structure of the main valve body and the second tongue plate structure of the valve seat portion are relatively fixed. The first direction is the screw-in direction, generally the right direction. It is worth noting that the specified depth can be set according to actual conditions. This application does not impose any restrictions on the specified depth, as long as the specified depth ensures that the insertion depth of the guide sleeve structure is sufficient to act as a radial limit.

[0106] During the rotation process, the second tongue plate structure is rotated from the second transition zone and buckled into the first slot structure, and the first tongue plate structure is rotated from the first transition zone and buckled into the second slot structure; during the rotation and buckling process, the progressive lifting belt of the limit platform structure of the valve seat part and the second part of the elastic telescopic rod of the locking structure of the main valve body are squeezed, and the elastic telescopic rod is gradually lifted upward until the first tongue plate structure of the main valve body is completely buckled into the second slot structure of the valve seat part and the first slot structure of the main valve body is completely buckled into the second tongue plate structure of the valve seat part. When the angle between the valve seat part and the main valve body in the horizontal direction is zero, the elastic telescopic rod is reset downward and extended from the rapid lifting transition zone of the limit platform structure.

[0107] Figure 9 A schematic diagram of relative rotation between a valve seat portion and a main valve body provided in this application, such as Figure 9 As shown in the figure, as the valve seat portion gradually rotates to the right relative to the main valve body, the valve seat portion and the main valve body begin to hook together. Figure 9As shown, the second tongue plate structure 51 of the valve seat rotates from the second transition zone 53 to snap into the first slot structure 12 of the main valve body. Simultaneously, the first tongue plate structure 11 of the main valve body rotates from the first transition zone 13 to snap into the second slot structure 52 of the valve seat, until the first tongue plate structure 11 of the main valve body and the second slot structure 52 of the valve seat are relatively fixed, and the first slot structure 11 of the main valve body and the second tongue plate structure 51 of the valve seat are relatively fixed. During the gradual snapping process, the valve seat is gradually lifted and vertically aligned with the main valve body. During the rotational insertion process, the progressive lifting band 541 of the stopper structure 54 of the valve seat portion squeezes the second portion 422 of the elastic telescopic rod 42 of the locking structure 4 of the main valve body, causing the rebound mechanism to be in a compressed state, causing the elastic telescopic rod 42 to gradually lift upward until the first tongue plate structure 11 of the main valve body is fully engaged with the second slot structure 52 of the valve seat portion, and the first slot structure 12 of the main valve body is fully engaged with the second tongue plate structure 51 of the valve seat portion. During the rotational insertion process, the horizontal angle α between the valve seat portion and the main valve body gradually decreases until it reaches zero. At this point, the valve seat portion and the main valve body are vertically aligned, and the elastic telescopic rod 42 quickly returns downward and extends from the rapid lifting transition band 542 of the stopper structure 54. The first portion 421 of the elastic telescopic rod 42 mates with the vertical surface of the stopper, thereby locking the relative positions of the valve seat portion and the main valve body, completing the assembly of the dispensing valve.

[0108] The rotation process continues until the outer surface of the tongue plate fits with the inner surface of the slot, at which point the angle α is reduced to zero. At the same time, the vertical matching between the valve seat and the main valve body is fully in place, and the elastic telescopic rod of the lock can just be reset downward from the transition zone at the rear end of the limiter in time. The straight section fits with the vertical surface at the rear end of the limiter to lock the circumferential position of the valve seat. Figure 1 As shown. Quick assembly operation completed

[0109] The present application also provides a disassembly method for a dispensing valve. The disassembly process of the dispensing valve is described below through a specific embodiment:

[0110] Use a designated tool to lift the elastic telescopic rod of the main valve body's locking structure upward, so that the second portion of the elastic telescopic rod contacts the lower edge of the rapid lifting transition zone of the valve seat's limit platform structure. Rotate the valve seat relative to the main valve body in a second direction until a designated angle is reached between the valve seat's guide sleeve structure and the main valve body's guide hole structure. Pull the valve seat and main valve body away from each other to complete disassembly of the dispensing valve. The second direction is the unscrewing direction, typically to the left.
