Description

Technical Field

[0001] This utility model relates to the field of water meter module packaging technology, specifically to a potting device. Background Technology

[0002] Water meter modules are used in a variety of environments, such as outdoor exposed environments and underground damp environments. The installation and use conditions are harsh. Furthermore, since existing water meter modules usually contain electronic structures such as circuit boards, the industry usually performs a potting operation between the bottom shell and the cover plate of the water meter module to eliminate the gap at the connection between the bottom shell and the cover plate and achieve the sealing of the water meter module in order to ensure the normal use and service life of the water meter module.

[0003] Currently, the equipment used for water meter module potting in the industry typically includes a potting machine and a placement fixture mounted on the platform of the potting machine. The placement fixture includes a placement plate with several placement holes, each with a shape consistent with the outer contour of the water meter module to be potted. This allows for manual placement of the assembled water meter module into the placement hole during potting, followed by filling the gap between the bottom shell and the cover plate of the water meter module with potting adhesive through the nozzle of the potting machine. While this structure meets the potting requirements of water meter modules, the placement holes are only contoured to mimic the outer contour of the water meter module. Furthermore, to facilitate the placement and removal of the water meter module within the placement holes, the size of the placement holes is usually slightly larger than the outer contour of the water meter module. This causes the water meter module to shift within the placement hole after placement, resulting in inaccurate positioning and potential loosening of the water meter module during potting. Consequently, defective products are prone to occur during the potting process. Furthermore, if the water meter module to be potted is loose, the nozzle may collide with the edge of the water meter module, affecting the service life of the potting machine. Summary of the Invention

[0004] To address the aforementioned problems in the existing technology, this invention aims to provide a potting device. This device involves installing a placement fixture with an adjustable clamping part on a platform. Each placement hole has a corresponding adjustable clamping part, ensuring that the water meter module to be potted within the placement hole is clamped against the corresponding adjustable clamping part. Furthermore, one side wall of the placement hole is used as a positioning reference surface, and the adjustable clamping part is positioned opposite this reference surface. This ensures that the water meter module to be potted within the placement hole is pushed against the positioning reference surface by the adjustable clamping part. This not only ensures stable clamping but also improves the accuracy of the clamping position, enhances potting quality, and increases product yield. Additionally, it avoids nozzle collisions, improving safety and extending service life.

[0005] The specific technical solution is as follows:

[0006] A potting device includes a potting machine, which has a platform and a nozzle, with the nozzle facing the platform. The platform is equipped with a placement fixture, which includes a placement plate with several placement holes. The outline of each placement hole matches the outer outline of the water meter module to be potted. An adjustable clamping part is provided on the placement plate next to each placement hole. Each adjustable clamping part includes a telescopic block, one side of which extends into the corresponding placement hole. The inner wall of each placement hole has several positioning reference surfaces, and each positioning reference surface corresponds to an adjustable clamping part. The adjustable clamping part and the corresponding positioning reference surface are located on opposite sides of the placement hole.

[0007] In the aforementioned potting device, the adjustable clamping part includes a sliding strip, a telescopic strip, a telescopic block, a telescopic spring, and a blocking block. The sliding strip is fixed to the bottom surface of the placement plate and includes a sliding hole arranged along its length. The telescopic strip is slidably disposed in the sliding hole and one end extends out of the sliding strip. The telescopic block is installed on the end of the telescopic strip that extends out of the sliding strip. A blocking block is provided on the sliding strip at the end opposite to the end of the telescopic strip that extends out of the sliding strip. The telescopic spring is installed between the sliding strip and the blocking block and its two ends abut against the sliding strip and the blocking block, respectively.

[0008] In the above-mentioned potting device, the plug is a countersunk screw, and the plug and the sliding strip are connected by a thread.

[0009] In the aforementioned potting device, the telescopic strip is a cylindrical structure, and a limiting surface covering its length direction is provided on the outer wall of the telescopic strip. The limiting surface is a plane arranged tangentially along the telescopic strip.

[0010] In the aforementioned potting device, the sliding strip includes a fixed plate, a front sliding sleeve, and a rear sliding sleeve. The fixed plate is a strip-shaped flat plate, and the front and rear sliding sleeves are arranged at intervals along its length. Both the front and rear sliding sleeves have through holes, and along the length of the fixed plate, the through holes on the front and rear sliding sleeves face each other to form a sliding hole. The telescopic strip passes through both through holes simultaneously. At the same time, the inner wall of each through hole is provided with a protrusion corresponding to the limiting surface. The protrusion abuts against the limiting surface, and a retaining ring is provided at the end of the telescopic strip near the block.

[0011] In the aforementioned potting device, a retaining ring is sleeved on the outer wall of the telescopic strip near the end of the plug, and a predetermined distance is provided between the retaining ring and the end face of the telescopic strip. One end of the telescopic spring is sleeved on the telescopic strip and the other end abuts against the retaining ring.

[0012] In the aforementioned potting device, a first connecting hole is provided on the end face of the end where the telescopic strip connects to the telescopic block, and a second connecting hole is provided on the telescopic block that passes through and corresponds to the first connecting hole. A screw passes through the second connecting hole and is threadedly connected to the first connecting hole. The second connecting hole is a countersunk hole.

[0013] In the above-mentioned potting device, one end of the telescopic block extends into the placement hole and is arranged on an inclined plane on the side near the opening of the placement hole, with one end of the inclined plane extending outside the outline of the placement hole.

[0014] In the aforementioned potting device, a plurality of positioning holes are provided on the platform, a plurality of fixing holes are provided on the placement plate, and a plurality of screws pass through the fixing holes and are threadedly locked into the positioning holes.

[0015] In the above-mentioned potting device, a support plate is provided on one side of the placement plate and in each placement hole, and the support plate is placed horizontally in the placement hole.

[0016] The positive effects of the above technical solution are:

[0017] The aforementioned potting device, by setting a placement fixture with several placement holes on the platform of the potting machine, and by setting an adjustable clamping part on the placement fixture at each placement hole, allows the water meter module to be potted to be clamped by the adjustable clamping part after being placed in the placement hole, thereby maintaining stability during potting. In addition, a positioning reference surface is set on the inner wall of the placement hole, and the positioning reference surface and the adjustable clamping part are arranged opposite to each other, so that the water meter module to be potted placed in the placement hole can be pushed onto the positioning reference surface by the adjustable clamping part. This not only meets the requirement of stable clamping but also ensures accurate clamping position, thereby improving product quality, reducing defective products, and preventing the problem of nozzle collision during potting, thus providing higher safety and a longer service life.

[0021] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 2 The technical solution provided by this utility model is described in detail, but the following content is not intended to limit this utility model.

[0022] Figure 1 This is a structural diagram of an embodiment of the potting device of this utility model; Figure 2 This is a structural diagram of the adjustable clamping part according to a preferred embodiment of the present invention. Figure 1 and Figure 2 As shown, the potting device provided in this embodiment includes a potting machine 1 and a placement fixture 2 disposed on the potting machine 1. At this time, the potting machine 1 has a platform 11 and a nozzle 12. The nozzle 12 is arranged facing the platform 11 so that the nozzle 12 can perform potting operation on the water meter module placed on the platform 11.

[0023] Specifically, the placement fixture 2 includes a placement plate 21 with legs at its bottom, which rest on the platform 11. Several placement holes 211 are provided on the placement plate 21, with the outlines of the holes matching the outer contours of the water meter module to be potted. This allows the water meter module to be placed through the placement holes 211, limiting its position and achieving initial positioning. Furthermore, an adjustable clamping part 3 is provided on the placement plate 21 beside each placement hole 211. Each adjustable clamping part 3 includes a telescopic block 33, with one side of the telescopic block 33 extending into the corresponding placement hole 211. This allows the telescopic block 33 to push the water meter module in the corresponding placement hole 211 to one side, providing conditions for subsequent clamping of the water meter module. In addition, several positioning reference surfaces 2111 are provided on the inner wall of each placement hole 211. The positioning reference surfaces 2111 are surfaces that completely fit the side wall of the water meter module to be potted. Furthermore, each positioning reference surface 2111 is provided with an adjustable clamping part 3. At the same time, the adjustable clamping part 3 and the corresponding positioning reference surface 2111 are respectively provided on both sides of the placement hole 211. That is, when the water meter module to be potted is placed in the corresponding placement hole 211, the extension block 33 of the corresponding adjustable clamping part can be used to tighten the module. The water meter module is pushed toward the positioning reference surface 2111, so that the side wall of the water meter module to be potted can completely abut against the positioning reference surface 2111. This not only clamps the water meter module to be potted, avoiding shaking during the potting process, ensuring potting quality and improving product qualification rate, but also ensures that the water meter module to be potted is more accurately positioned in the corresponding placement hole 211, avoiding collision between the nozzle 12 of the potting machine 1 and the side of the water meter module, resulting in better safety protection and longer service life.

[0024] More specifically, such as Figure 2As shown, the adjustable clamping part 3 for clamping the water meter module to be potted includes a sliding bar 31, a telescopic bar 32, a telescopic block 33, a telescopic spring 34, and a blocking block 35. During assembly, the sliding bar 31 is fixed to the bottom surface of the placement clamping plate to facilitate pushing against the side wall of the water meter module to be potted, which is placed in the placement hole 211. Furthermore, the sliding bar 31 includes a sliding hole arranged along its length. The telescopic bar 32 is slidably disposed within the sliding hole, with one end extending beyond the sliding bar 31. The sliding hole provides guidance for the telescopic movement of the telescopic bar 32, ensuring its stability during movement. Additionally, the telescopic block 33 is installed on the end of the telescopic bar 32 extending beyond the sliding bar 31, allowing the telescopic movement of the telescopic bar 32 to drive the telescopic block 33 to move. This also ensures the stability of the telescopic block 33 during movement, providing conditions for the subsequent stable clamping of the water meter module to be potted. Furthermore, a block 35 is provided on the sliding strip 31 at the end opposite to the extension of the telescopic strip 32. At the same time, a telescopic spring 34 is installed between the sliding strip 31 and the block 35, with both ends abutting against the sliding strip 31 and the block 35 respectively. That is, the block 35 also forms an abutting structure on the sliding strip 31, so that both ends of the telescopic spring 34 can have corresponding abutting bases. The telescopic spring 34 provides a force for the telescopic strip 32 to push the block 35 toward the corresponding placement hole 211 and push against the water meter module to be potted.

[0025] More specifically, the plug 35 used to abut against the telescopic spring 34 is a countersunk screw, and the plug 35 and the sliding strip 31 are connected by threads. Preferably, the sliding strip 31 is provided with a protrusion with a threaded adjustment hole. The plug 35 is threaded into the threaded adjustment hole on the protrusion, and one end of the plug 35 extends out of the threaded adjustment hole and abuts against the telescopic spring 34. This allows the operator to adjust the preload of the telescopic spring 34 by turning the plug 35. That is, when a greater force is needed to clamp the water meter module to be sealed, the telescopic spring 34 can be further compressed by turning the plug 35. The structure is more flexible and meets different usage needs.

[0026] More specifically, the telescopic strip 32 has a cylindrical structure, which can be directly machined, making processing more convenient. Furthermore, a limiting surface 321 covering its length direction is provided on the outer wall of the telescopic strip 32, ensuring that the telescopic movement of the strip 32 is guided by the limiting surface 321. Simultaneously, the limiting surface 321 is set as a plane arranged tangentially to the telescopic strip 32, ensuring that the limiting surface 321 remains within the same plane height when the telescopic strip 32 extends or retracts along its axial direction, resulting in better guiding effect and preventing jamming.

[0027] More specifically, the sliding strip 31 that guides the movement of the telescopic strip 32 includes a fixed plate 311, a front sliding sleeve 312, and a rear sliding sleeve 313. In this case, the fixed plate 311 is a strip-shaped flat plate, which meets the telescopic requirements of the telescopic strip 32 in the length direction. Meanwhile, front sliding sleeves 312 and rear sliding sleeves 313 are arranged at intervals along the length of the fixed plate 311. Both front sliding sleeves 312 and rear sliding sleeves 313 have through holes 3121. Along the length of the fixed plate 311, the through holes 3121 on the front sliding sleeves 312 and rear sliding sleeves 313 face each other and form sliding holes. The telescopic strip 32 passes through both through holes 3121 at the same time. That is, the two ends of the telescopic strip 32 are supported and guided by the sliding holes formed by the through holes 3121 on the front sliding sleeves 312 and rear sliding sleeves 313, so as to ensure that the telescopic strip 32 can be more stable when it is extended and retracted. In addition, stable guidance can be achieved by the cooperation of the spaced front sliding sleeves 312 and / or the sliding sleeves, without the need to design an overall wrap-around guide structure, which reduces the weight of the device and saves manufacturing costs. Meanwhile, a protrusion corresponding to the limiting surface 321 is provided on the inner wall of each perforation 3121. In this case, the protrusion and the corresponding front sliding sleeve 312 or rear sliding sleeve 313 form an integral structure, resulting in higher structural strength. Furthermore, by abutting the protrusion against the limiting surface 321, the mutual abutment between the limiting surface 321 and the protrusion effectively prevents the telescopic strip 32 from rotating circumferentially within the sliding hole during telescopic movement, ensuring the stability of the telescopic block 33 and avoiding the problem of the telescopic block 33 rotating and failing to fit against the side wall of the water meter module to be potted, or interfering with the movement of the placement plate 21 itself. Moreover, a retaining ring 322 is provided at the end of the telescopic strip 32 near the blocking block 35. The retaining ring 322 forms a limit at the end of the telescopic strip 32, preventing the telescopic strip 32 from detaching from the sliding hole under the action of the telescopic spring 34, resulting in a more rational structural design.

[0028] More specifically, the retaining ring 322 is fitted onto the outer wall of the end of the telescopic strip 32 near the block 35, and a predetermined distance is provided between the retaining ring 322 and the end face of the telescopic strip 32, so that the end of the telescopic strip 32 has a predetermined length that is not affected by the retaining ring 322. In addition, one end of the telescopic spring 34 is fitted onto the telescopic strip 32 and the other end abuts against the retaining ring 322. That is, the retaining ring 322 serves both as a limiting structure to prevent the telescopic strip 32 from slipping off and as a support structure for the telescopic spring 34 to abut against the telescopic strip 32. Furthermore, it allows one end of the telescopic spring 34 to be fitted onto the outside of the telescopic strip 32 while having a stable support structure, improving the stability of the telescopic spring 34 after installation and preventing it from falling off during use. Preferably, the retaining ring 322 can be a retaining ring that is snapped onto the outside of the telescopic strip 32, facilitating the installation of the telescopic strip 32 into the sliding hole.

[0029] More specifically, a first connecting hole is provided on the end face of the telescopic strip 32 where it connects to the telescopic block 33. Simultaneously, a second connecting hole 331, corresponding to the first connecting hole, is provided on the telescopic block 33. When the telescopic block 33 is installed on the telescopic strip 32, a screw can pass through the second connecting hole 331 and be threaded into the first connecting hole. This facilitates the installation and removal of the telescopic block 33 on the telescopic strip 32, thus facilitating the installation of the telescopic strip 32 into the sliding hole of the sliding strip 31. Furthermore, it provides the possibility of replacing different types of telescopic blocks 33 with different models and specifications of water meter modules to be potted, resulting in a more flexible structure and better adaptability. Moreover, the second connecting hole 331 is a countersunk hole, concealing the screw head and maintaining the flatness of the side of the telescopic block 33. This allows the telescopic block 33 to fit tightly against the side wall of the water meter module to be potted, improving the clamping effect.

[0030] More specifically, the end of the telescopic block 33 extending into the placement hole 211 and positioned at an angle near the opening of the placement hole 211 is arranged on the side. Since the end of the telescopic block 33 in the placement hole 211 is initially located inside the telescopic hole, when the water meter module to be potted is placed in the placement hole 211, the end of the telescopic block 33 extending into the placement hole 211 will press against the bottom of the water meter module to be potted, preventing the water meter module to be potted from entering the placement hole 211. However, by setting an angle on the telescopic block 33, the side edge of the bottom of the water meter module to be potted can contact the angle immediately. When the water meter module to be potted is pressed down, the angle will push the telescopic block 33 in the opposite direction, causing the telescopic spring 34 to deform and allowing the telescopic block 33 to move outward toward the placement hole 211, thereby allowing the water meter module to be potted to smoothly enter the placement hole 211. In addition, one end of the inclined surface extends outside the outline of the placement hole 211, so that after the water meter module to be potted enters the placement hole 211, the bottom side edge of the water meter module to be potted always contacts the inclined surface of the telescopic block 33 at the first moment, and there will be no jamming problem, making the structural design more reasonable.

[0031] More specifically, the platform 11 is provided with several positioning holes 111, and the placement plate 21 is provided with several fixing holes. When the placement clamp 2 is installed on the platform 11, it can be threaded into the positioning holes 111 by passing a screw through the fixing holes, thus achieving stable installation of the placement clamp 2 on the platform 11. In addition, different specifications and models of placement clamps 2 can be adapted by selecting different positioning holes 111, making the device more adaptable.

[0032] More specifically, a support plate 2112 is also provided on one side of the placement plate 21 and located within each placement hole 211. The support plate 2112 is horizontally placed within the placement hole 211. Preferably, the support plate 2112 is formed without penetrating the placement hole 211, that is, the thickness of the support plate 2112 is less than the thickness of the placement plate 21, so that the support plate 2112 and the placement plate 21 are an integral structure without the need for additional assembly, resulting in higher structural strength. In addition, the support plate 2112 can restrict the further downward movement of the water meter module to be potted within the placement hole 211, which also provides conditions for the stable placement of the water meter module to be potted within the placement hole 211.

[0033] The potting device provided in this embodiment includes a potting machine 1 and a placement clamp 2. By installing a placement clamp 2 with a plurality of placement holes 211 on the platform 11 of the potting machine 1, and by providing an adjustable clamping part 3 with a telescopic block 33 at each placement hole 211, the water meter module to be potted can be clamped by the telescopic block 33 of the adjustable clamping part 3 when placed in the placement hole 211, maintaining the stability of the water meter module during potting, improving product quality and pass rate. In addition, a positioning reference surface 2111 is provided on the inner wall of each placement hole 211, and each positioning reference surface 2111 corresponds to an adjustable clamping part 3 located on both sides of the corresponding placement hole 211. This allows the telescopic block 33 to push the water meter module to be potted toward the positioning reference surface 2111, ensuring the accurate clamping position of the water meter module to be potted, avoiding the problem of collision between the nozzle 12 of the potting machine 1 and the side of the water meter module during the potting process, thus improving safety and extending service life.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
