Description

Technical Field

[0001] This invention relates to the field of mechanical operation technology, and in particular to a quick-release valve body structure and a soldering machine. Background Technology

[0002] In industrial fields such as electronics manufacturing, semiconductor packaging, and precision assembly, automated equipment such as solder paste spraying machines and glue dispensing machines play a crucial role. These machines typically consist of two main parts: the core actuator valve (such as the solder paste spraying valve or glue dispensing valve) and the valve drive unit (such as a multi-axis robotic arm or an XYZ linear drive module). The actuator valve is responsible for performing precise processing operations such as solder paste spraying and glue coating, while the valve drive unit, through program control, drives the actuator valve to move at high speed and high precision along a predetermined trajectory to achieve complex work paths.

[0003] Currently, the connection between the valve body and the valve body drive unit generally adopts a mechanical rigid fixing method, the most typical of which is to directly lock the valve body to the end flange or mounting surface of the drive unit with bolts (or screws). This connection method exhibits good rigidity and reliability during long-term stable operation of the equipment, and can ensure the positional accuracy of the valve body during high-speed movement.

[0004] However, the drawbacks of this traditional connection method are significant during equipment maintenance. As a precision component, the valve body is susceptible to material residue, wear, or electrical faults during continuous operation, requiring frequent preventative maintenance, cleaning, repair, or replacement. Each operation necessitates technicians using specialized tools to loosen or tighten multiple bolts one by one, a tedious and time-consuming process. This not only reduces equipment maintenance efficiency and increases production line downtime but also increases the labor intensity of operators and the risk of component damage due to improper operation, caused by limited operating space and repetitive manual labor. In production environments requiring rapid changeovers or process adjustments, this disassembly and assembly efficiency becomes a bottleneck in improving overall flexibility.

[0005] Therefore, the existing bolted connection between the valve body and the drive unit is no longer adequate for the demands of modern intelligent manufacturing for efficient equipment maintenance, rapid response, and flexible production. A novel valve body assembly / disassembly structure is urgently needed to enable quick and easy assembly and disassembly of the valve body, thereby improving maintenance efficiency.

[0006] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] One objective of this invention is to provide a quick-release valve body structure and a soldering machine, which enables quick and easy disassembly and assembly of the valve body, thereby improving maintenance efficiency.

[0008] To achieve the above objectives, the present invention provides a quick-release valve body structure and a soldering machine, comprising:

[0009] A replaceable module, comprising a replaceable docking plate with a limiting window on the back, a replaceable circuit board on the back of the replaceable docking plate, and an actuator valve body mounted on the front of the replaceable docking plate and electrically connected to the replaceable circuit board.

[0010] The multiplexing module includes a multiplexing docking plate disposed opposite to the replaceable docking plate, a valve body drive unit whose drive end is connected to the multiplexing docking plate to drive the multiplexing docking plate to move, a multiplexing circuit board mounted on the multiplexing docking plate and disposed opposite to the replaceable circuit board, a rotating pressure plate rotatably mounted on the side of the multiplexing docking plate near the replaceable docking plate, and a pressure plate rotary drive unit that drives the rotating pressure plate to rotate.

[0011] in,

[0012] The rotating pressure plate, driven by the pressure plate rotary drive unit, has a switchable loose position and a tight position:

[0013] In the released position, the rotating pressure plate rotates inward until it is completely within the axial projection boundary of the limiting window, so that the rotating pressure plate can pass through the limiting window;

[0014] At the clamping position, the rotating pressure plate extends into the limiting window and rotates outward to cooperate with the multiplex docking plate to press against the inner edge of the limiting window, thereby locking the replaceable docking plate onto the multiplex docking plate and making the replaceable circuit board electrically connected to the multiplex circuit board.

[0015] Optionally, the pressure plate rotary drive unit includes:

[0016] An axially lateral sliding slider is slidably connected to the reusable docking plate along a first direction, and the circumferential surface of the axially lateral sliding slider near the replaceable docking plate is provided with a limiting guide groove extending along a second direction for one end of the rotating pressure plate to be movably embedded; wherein, the first direction is parallel to the docking direction of the two circuit boards, and the second direction is perpendicular to the first direction.

[0017] A slider direct drive mechanism is mounted and fixed on the multiplex docking plate, and the drive end of the slider direct drive mechanism is connected to the axial transverse slider. It is used to cause the rotating pressure plate to rotate between the loose position and the pressing position when the axial transverse slider is driven to slide back and forth along the first direction.

[0018] Optionally, the rotating pressure plate has a rotating shaft in the middle that is rotatably connected to the reusable docking plate, one end of the rotating pressure plate has a limiting part that is movably embedded in the limiting guide groove, and the other end of the rotating pressure plate has a pressing part for pressing the inner edge of the limiting window.

[0019] Optionally, the distance from the rotating shaft to the limiting part is greater than the distance from the rotating shaft to the pressing part.

[0020] Optionally, both the replaceable circuit board and the reusable circuit board include a circuit board body and several conductive mating parts;

[0021] Of the replaceable circuit board and the reusable circuit board, the conductive contact portion of one is a metal sheet, and the conductive contact portion of the other is a spring probe.

[0022] Optionally, the multiplexed circuit board is mounted on the multiplexed mating plate and protrudes outward relative to the multiplexed mating plate;

[0023] The replaceable docking plate has a docking groove in the area corresponding to the multiplex circuit board, into which the multiplex circuit board extends, and the replaceable circuit board is installed in the docking groove.

[0024] Optionally, the back of the replaceable docking plate is provided with an outwardly protruding alignment pin;

[0025] The reusable docking plate is provided with a pin hole for the alignment pin to be inserted;

[0026] Wherein, the protrusion dimension of the alignment pin relative to the replaceable mating plate is greater than the protrusion dimension of the replaceable circuit board relative to the replaceable mating plate.

[0027] Optionally, the replaceable docking plate and the reusable docking plate are magnetically connected.

[0028] Optionally, the actuator valve body is a solder spray valve or a glue dispensing valve.

[0029] On the other hand, a tin spraying machine is provided, including a workpiece transverse platform for receiving workpieces and at least one of the valve body quick-release structures located above the workpiece transverse platform.

[0030] The actuator valve body is a solder spray valve.

[0031] The beneficial effects of this invention are: it provides a quick-release valve body structure and a soldering machine.

[0032] When installing or replacing a replaceable module containing an actuator valve body, the operator first roughly aligns the replaceable docking plate of the replaceable module with the reusable docking plate of the reusable module. At this point, the pressure plate rotary drive unit drives the rotating pressure plate inward to the released position, causing the rotating pressure plate to extend axially, its outer contour not exceeding the projection boundary of the limiting window in the axial direction (i.e., the docking direction). In this way, the rotating pressure plate will not obstruct the approach and contact of the replaceable docking plate.

[0033] Once the replaceable docking plate is brought close to the reused docking plate and the replaceable circuit board and reused circuit board are initially aligned, the rotating pressure plate is inserted into the limiting window on the back of the replaceable docking plate. The pressure plate rotary drive unit then drives the rotating pressure plate to rotate towards the pressing position. During this process, the rotating pressure plate rotates outward and presses against the inner edge of the limiting window. At this time, the rotating pressure plate and the reused docking plate work together like a "buckle" or "hook," firmly clamping the replaceable docking plate onto the reused docking plate. Simultaneously, because the two docking plates are tightly pressed together, the replaceable circuit board and reused circuit board mounted on them also achieve a stable and reliable electrical connection, thereby providing an electrical path for the normal operation of the valve body.

[0034] Therefore, the quick-release valve body structure and tin spraying machine provided by the present invention can realize the quick and easy disassembly and assembly of the valve body, thereby improving maintenance efficiency. Attached Figure Description

[0061] This embodiment provides a quick-release valve body structure and a soldering machine, which enables quick and easy disassembly and assembly of the valve body, thereby improving maintenance efficiency.

[0062] Example 1

[0063] See Figures 1-5 This embodiment provides a quick-release valve body structure, including:

[0064] The replaceable module 200 includes a replaceable docking plate 1 with a limiting window 101 on the back, a replaceable circuit board 2 located on the back of the replaceable docking plate 1, and an actuator valve body 3 installed on the front of the replaceable docking plate 1 and electrically connected to the replaceable circuit board 2.

[0065] The multiplexing module 300 includes a multiplexing docking plate 4 disposed opposite to the replaceable docking plate 1, a valve body drive unit 5 whose drive end is connected to the multiplexing docking plate 4 to drive the multiplexing docking plate 4 to move, a multiplexing circuit board 6 mounted on the multiplexing docking plate 4 and disposed opposite to the replaceable circuit board 2, a rotating pressure plate 7 rotatably mounted on the side of the multiplexing docking plate 4 near the replaceable docking plate 1, and a pressure plate rotary drive unit 8 that drives the rotating pressure plate 7 to rotate.

[0066] in,

[0067] The rotating pressure plate 7, driven by the pressure plate rotary drive unit 8, has a switchable loose position and a tight position:

[0068] In the released position, the rotating pressure plate 7 rotates inward until it is completely within the axial projection boundary of the limiting window 101, so that the rotating pressure plate 7 can pass through the limiting window 101;

[0069] At the pressing position, the rotating pressure plate 7 extends into the limiting window 101 and rotates outward to cooperate with the multiplex docking plate 4 to press against the inner edge of the limiting window 101, thereby locking the replaceable docking plate 1 onto the multiplex docking plate 4 and making the replaceable circuit board 2 electrically connected to the multiplex circuit board 6.

[0070] The quick-release valve body structure and soldering machine provided in this embodiment mainly involve two states in actual operation: "installation / replacement" and "locking / operation".

[0071] When it is necessary to install or replace a replaceable module 200 containing an actuator valve body 3, the operator first roughly aligns the replaceable docking plate 1 of the replaceable module 200 with the reuse docking plate 4 of the reuse module 300. At this time, the pressure plate rotary drive unit 8 drives the rotating pressure plate 7 to rotate inward to the released position, so that the rotating pressure plate 7 extends axially and its outer contour does not exceed the projection boundary of the limiting window 101 in the axial direction (i.e., the docking direction). In this way, the rotating pressure plate 7 will not obstruct the approach and contact of the replaceable docking plate 1;

[0072] When the replaceable docking plate 1 is brought close to the reused docking plate 4 and the replaceable circuit board 2 and reused circuit board 6 are initially aligned, the rotating pressure plate 7 is inserted into the limiting window 101 on the back of the replaceable docking plate 1, and the pressure plate rotary drive unit 8 begins to drive the rotating pressure plate 7 to rotate toward the pressing position. During this process, the rotating pressure plate 7 rotates outward and presses against the inner edge of the limiting window 101. At this time, the rotating pressure plate 7 and the reused docking plate 4 work together like a "buckle" or "hook" to firmly clamp the replaceable docking plate 1 onto the reused docking plate 4. At the same time, because the two docking plates are tightly pressed together, the replaceable circuit board 2 and reused circuit board 6 mounted on them also achieve a stable and reliable electrical connection, thereby providing an electrical path for the normal operation of the actuator valve body 3.

[0073] This solution, through ingenious mechanical structure design, achieves rapid disassembly and reliable locking of the module containing the actuator valve body 3. Its core lies in the rotatable rotating pressure plate 7 and its corresponding limiting window 101. By switching between two positions, the contradiction between "avoidance for passage" and "rotation for clamping" is cleverly resolved. In the loosened position, the rotating pressure plate 7 completely avoids interference, enabling interference-free disassembly and assembly of the module and greatly improving replacement efficiency. In the clamping position, the rotating pressure plate 7 generates a clamping force parallel to the docking direction through its rotational motion, producing a large locking force to ensure that the two modules will not loosen even in high-speed, vibrating industrial environments, while also ensuring the stability of the electrical connection between the circuit boards. The entire locking and unlocking process can be completed automatically or semi-automatically by the pressure plate rotary drive unit 8, making operation simple and quick.

[0074] In this embodiment, the pressure plate rotary drive unit 8 includes:

[0075] An axial transverse sliding slider 801 is slidably connected to the reusable docking plate 4 along a first direction, and the circumferential surface of the axial transverse sliding slider 801 near the end of the replaceable docking plate 1 is provided with a limiting guide groove 8011 extending along a second direction for one end of the rotating pressure plate 7 to be movably embedded; wherein, the first direction is parallel to the docking direction of the two circuit boards, and the second direction is perpendicular to the first direction.

[0076] A slider direct drive mechanism 802 is installed and fixed on the reusable docking plate 4, and the driving end of the slider direct drive mechanism 802 is connected to the axial transverse slider 801. It is used to make the rotating pressure plate 7 rotate between the loose position and the pressing position when the axial transverse slider 801 is driven to slide back and forth along the first direction.

[0077] Furthermore, the rotating pressure plate 7 has a rotating shaft 701 in the middle that is rotatably connected to the reusable docking plate 4, a limiting part 702 in the limiting guide groove 8011 that is movably embedded at one end of the rotating pressure plate 7, and a pressing part 703 for pressing the inner edge of the limiting window 101 at the other end of the rotating pressure plate 7.

[0078] In this embodiment, the rotating pressure plate 7 is specifically designed as an integrated lever component with clearly defined functional zones. The central pivot 701 engages with a bearing or shaft hole on the reusable docking plate 4, forming the fulcrum for the rotational movement of the rotating pressure plate 7. The limiting part 702 is movably embedded in the limiting guide groove 8011 of the axial transverse slider 801, serving as the input end to receive the push-pull force from the slider direct drive mechanism 802. The clamping part 703 is the working end that performs the locking function. When the axial transverse slider 801 moves and drives the limiting part 702 to move through the limiting guide groove 8011, the rotating pressure plate 7 rotates around the pivot 701, causing the clamping part 703 to generate an arc-shaped swing trajectory centered on the pivot 701. In the clamping position, the specific contour of the clamping part 703 rotates precisely to a position where it can clamp or hook the inner edge of the limiting window 101.

[0079] During operation, the slider direct drive mechanism 802 (e.g., cylinder, motor screw, etc.) is activated, driving the axial transverse slider 801 to reciprocate along a direction parallel to the mating direction of the two circuit boards (i.e., the first direction). Since one end of the rotating pressure plate 7 is movably embedded in the limiting guide groove 8011 on the axial transverse slider 801, and the limiting guide groove 8011 extends along a second direction perpendicular to the first direction, the linear motion of the axial transverse slider 801 is converted into constraint and drive on one end of the rotating pressure plate 7. Specifically, when the slider direct drive mechanism 802 drives the axial transverse slider 801 to slide away from the rotation axis of the rotating pressure plate 7, the groove wall of the limiting guide groove 8011 will pull the embedded end (i.e., the limiting part 702) of the rotating pressure plate 7 through the contact surface, forcing the rotating pressure plate 7 to rotate inward to the released position; conversely, when the axial transverse slider 801 slides in the opposite direction, it will push the embedded end (i.e., the limiting part 702) of the rotating pressure plate 7, causing it to rotate outward to the pressing position. By controlling the stroke of the axial transverse slider 801, the rotation angle of the rotating pressure plate 7 can be precisely controlled, enabling reliable switching between the two positions.

[0080] Optionally, the distance from the pivot 701 to the limiting part 702 is greater than the distance from the pivot 701 to the pressing part 703. Due to the lever principle, a small linear driving force applied to the limiting part 702 can generate a larger locking force in the pressing part 703, which has a longer lever arm, thereby completing the locking action efficiently and reliably.

[0081] In this embodiment, the limiting part 702 is cylindrical, and its diameter is smaller than the depth of the limiting guide groove 8011 along the second direction. The cylindrical limiting part 702 can smoothly roll or slide within the limiting guide groove 8011, effectively reducing frictional resistance during movement. The key design element is that the diameter of the limiting part 702 is intentionally set to be smaller than the depth of the limiting guide groove 8011 along the second direction. This means that within the limiting guide groove 8011, the cylindrical limiting part 702 has a small clearance in the direction perpendicular to the slider's movement. This clearance allows the limiting part 702 of the rotating pressure plate 7 to have a certain adaptive displacement space in the depth direction of the limiting guide groove 8011 during rotation. It can automatically compensate for part machining tolerances, assembly errors, and minor deformations that may occur during long-term use, ensuring that during the entire process of the axially lateral slider 801 driving the rotating pressure plate 7 to rotate, there will be no rigid interference, jamming, or additional wear due to minor dimensional deviations.

[0082] In this embodiment, both the replaceable circuit board 2 and the reusable circuit board 6 include a circuit board body and several conductive mating parts;

[0083] Of the replaceable circuit board 2 and the multiplexed circuit board 6, the conductive contact part of one is a metal sheet and the conductive contact part of the other is a spring probe.

[0084] Both the replaceable circuit board 2 and the multiplexed circuit board 6 are provided with several conductive contacts for transmitting power, control signals, or data. Specifically, the conductive contacts on one circuit board (e.g., the multiplexed circuit board 6) are in the form of metal sheets (such as gold-plated pads, copper foil contacts, etc.), while the conductive contacts on the other circuit board (e.g., the replaceable circuit board 2) are correspondingly set as spring probes (also called spring pins or pogo pins). When the rotating pressure plate 7 presses the two contact plates into the working position, the head of the spring probe on the replaceable circuit board 2 will precisely press against the metal sheet of the multiplexed circuit board 6. The spring inside the spring probe is compressed, and its elastic restoring force ensures a continuous, tight, and low-resistance physical contact between the probe tip and the surface of the metal sheet, thereby establishing a stable electrical connection path. Multiple such spring probes and metal sheet contacts are arranged in parallel to complete all the necessary electrical connections.

[0085] In this embodiment, the multiplexed circuit board 6 is mounted on the multiplexed docking plate 4 and protrudes outward relative to the multiplexed docking plate 4;

[0086] The replaceable docking plate 1 is provided with a docking groove 103 in the area corresponding to the multiplex circuit board 6, into which the multiplex circuit board 6 extends, and the replaceable circuit board 2 is installed in the docking groove 103.

[0087] In the multiplexing module 300, the multiplexing circuit board 6 is not mounted flush with the surface of the multiplexing docking plate 4. Instead, it is mounted such that the side with the conductive docking portion (i.e., the back side) protrudes outward by a certain distance relative to the surface of the multiplexing docking plate 4, forming a boss structure. Correspondingly, on the replaceable docking plate 1 of the replaceable module 200, a recessed docking groove 103 is formed in the area opposite to the multiplexing circuit board 6. The replaceable circuit board 2 is installed at the bottom of this docking groove 103. When the two modules dock, the outwardly protruding multiplexing circuit board 6 acts as a "guide head," first inserting into the docking groove 103 of the replaceable docking plate 1. This insertion process physically guides the relative position of the two docking plates, ensuring that the two circuit boards can be basically aligned on the plane. As docking continues, the protruding multiplexing circuit board 6 fully enters the docking groove 103, and its conductive docking portion contacts the conductive docking portion of the replaceable circuit board 2 installed at the bottom of the groove. Finally, under the clamping force of the rotating pressure plate 7, a tight electrical connection is achieved.

[0088] Optionally, the back of the replaceable docking plate 1 is provided with an outwardly protruding alignment pin 102;

[0089] The reusable docking plate 4 is provided with a pin hole 401 for the alignment pin 102 to be inserted;

[0090] Wherein, the protrusion dimension of the alignment pin 102 relative to the replaceable mating plate 1 is greater than the protrusion dimension of the replaceable circuit board 2 relative to the replaceable mating plate 1.

[0091] Furthermore, the replaceable docking plate 1 and the reusable docking plate 4 are magnetically connected.

[0092] This implementation provides a logically clear, step-by-step precision alignment and connection scheme. In actual docking operations, the alignment functions work collaboratively in the following order:

[0093] (1) First, when the operator moves the replaceable docking plate 1 of the replaceable module 200 to the multiplex docking plate 4, since the protrusion dimension of the alignment pin 102 relative to the replaceable docking plate 1 is larger than the protrusion dimension of the replaceable circuit board 2, the tip of the alignment pin 102 will first contact and insert into the pin hole 401 of the multiplex docking plate 4. This process utilizes the precision fit of small gaps to forcibly correct all deviations of the two docking plates in the plane, achieving primary, high-precision circumferential positioning.

[0094] (2) After the pins are precisely positioned and the relative positions of the two mating plates are fully constrained, the circuit board guide structure is seamlessly connected. At this time, the reusable circuit board 6 with a shorter protrusion dimension smoothly enters the mating groove 103 of the replaceable mating plate 1 without any risk of lateral collision. This "boss-groove" fit further ensures that the replaceable circuit board 2 and the reusable circuit board 6 achieve perfect alignment under the determined precise positioning.

[0095] (3) When the pin is fully inserted and the circuit board is also in the mating slot 103, and the two mating plates are in the correct relative positions, the magnetic connection begins to function. The magnetic components (such as magnets and magnetic conductors) on the contact surfaces of the two mating plates generate an attraction force, quickly pulling them together. This magnetic force provides a stable and uniform preload, keeping the entire module stable before the subsequent locking operation of the rotating pressure plate 7, and ensuring initial tight contact between the circuit board contacts.

[0096] (4) After the magnetic attraction achieves the initial pre-tightening positioning, the rotating pressure plate 7 is used to rotate and press the replaceable docking plate 1 to complete the locking.

[0097] In this embodiment, the actuator valve body 3 is either a solder spraying valve or a dispensing valve. When the actuator valve body 3 is a solder spraying valve, this quick-release structure is used in the solder spraying process. The solder spraying valve, through its internal precision control, sprays molten solder paste into a specific shape onto designated locations on workpieces such as circuit boards. When the actuator valve body 3 is a dispensing valve, this structure is used in the dispensing process. The dispensing valve is used to precisely apply fluid materials such as sealant, conductive adhesive, and glue. Both solder spraying valves and dispensing valves are precision fluid control devices, requiring stable mechanical installation and reliable electrical connections to ensure their operational accuracy. This quick-release structure, through the aforementioned mechanical locking and circuit board docking method, precisely meets the core requirements of these valve bodies for rapid replacement and maintenance, as well as high-reliability connections.

[0098] Example 2

[0099] See Figure 6This embodiment provides a solder spraying machine, including a workpiece transverse platform 100 for receiving workpieces, and at least one quick-release valve body structure located above the workpiece transverse platform 100 as described in Embodiment 1; wherein, the actuating valve body 3 is a solder spraying valve.

[0100] In this embodiment, the solder spraying machine operates by having the workpiece transverse platform 100 move the workpiece to a pre-set position below the solder spraying valve. The valve body drive unit 5, according to control commands, drives the entire multiplex module 300 and the replaceable module 200 (including the solder spraying valve) locked to it to perform precise movements, adjusting the height and position of the solder spraying valve relative to the workpiece. Once everything is in place, the solder spraying valve opens under the control of an electrical signal, performing precise solder spraying. Depending on production needs, the solder spraying machine can be flexibly configured with different numbers of quick-release valve bodies. For example, configuring a single valve results in a single-valve solder spraying machine, suitable for single processes or low-capacity requirements; configuring two valve bodies forms a dual-valve asynchronous solder spraying structure, where the two valve bodies can work alternately or use different solder pastes, improving efficiency or enabling complex processes; configuring more valve bodies allows for the construction of a highly efficient multi-valve synchronous or asynchronous solder spraying system.
