Description
Technical Field
[0001] The utility model relates to the technical field of PCB board positioning devices, in particular to a tool for gluing PCB boards. Background Art
[0002] PCBs, also known as printed circuit boards, are crucial circuit components that provide electrical connections for electronic components. During PCB manufacturing, the bottoms of electronic components are soldered to the PCB. However, due to the height of some components, soldering alone cannot guarantee their stability. These components are prone to falling off or becoming damaged during transportation or use due to vibration. Therefore, a sealant is applied between adjacent electronic components. This sealant, after curing, provides mutual support between the components, ensuring a more stable and reliable attachment to the PCB.
[0003] In the prior art, PCBs are typically placed flat for gluing, or placed on a plate-shaped positioning fixture to secure the PCB for subsequent gluing. However, some electronic components on the PCB are relatively tall, and when applying gluing between adjacent electronic components, the spacing available for gluing is too large. In practice, due to the fluidity of the glue, it is difficult to ensure accurate gluing locations. This results in inaccurate bonding and fixing positions between the electronic components after the sealant cures. Furthermore, to ensure reliable fixing of the electronic components, repeated gluing operations are required, requiring excessive amounts of sealant and resulting in high costs. Utility Model Content
[0004] The purpose of the present utility model is to provide a tool for gluing PCB boards, so as to solve the problem in the prior art that, when performing gluing operations on PCB boards, the spacing between higher components on the PCB boards is large, and because the glue liquid has a certain fluidity, it is difficult to ensure the accurate gluing positions, thereby requiring multiple operations and requiring an excessive amount of glue.
[0005] To achieve the above-mentioned purpose, the technical solution of the tooling for gluing PCB boards provided by the present invention is: it includes a base frame, the base frame is provided with a bearing structure for positioning and supporting the PCB board, the base frame is also provided with a glue supporting assembly, the glue supporting assembly includes a glue supporting part for extending between two adjacent electronic components on the PCB board and fitting with the sides of the two electronic components, and the upper space between the electronic components on both sides and the glue supporting part forms a gluing space for injecting glue liquid.
[0006] As a further improvement, the height of the rubber support member satisfies the requirement of being located close to the top of the electronic component during use.
[0007] As a further improvement, a glue blocking member is provided on at least one side of the glue supporting member, and the glue blocking member is used to stick to one side of the electronic component after the glue supporting member extends into between two adjacent electronic components, so as to block the end of the glue space.
[0008] As a further improvement, the rubber support assembly also includes a mounting plate horizontally slidably arranged on the base frame, the rubber support part is fixed on the mounting plate, and the rubber support part includes rubber support arms arranged at intervals, and the rubber support arms extend into and out from between two adjacent electronic components during the horizontal sliding of the mounting plate.
[0009] As a further improvement, a glue blocking member is provided on at least one side of the glue supporting member, and the glue blocking member is used to stick to one side of the electronic component after the glue supporting arm extends between two adjacent electronic components, so as to block the end of the glue application space.
[0010] As a further improvement, the rubber stopper is a stop plate extending along the arrangement direction of the rubber supporting arms, and the stop plate is arranged on the mounting plate at a position close to the end of the rubber supporting member.
[0011] As a further improvement, the base frame is L-shaped, including a horizontal bottom plate and a vertical upright plate, the bearing structure is arranged on the horizontal bottom plate, and the rubber supporting member is slidably arranged on the vertical upright plate.
[0012] As a further improvement, a slot is provided on the vertical plate, and a guide plate extending along the sliding direction of the rubber supporting member is provided at the slot opening to guide the mounting plate to slide in the slot.
[0013] As a further improvement, the bearing structure is a positioning column fixed on the base plate, and the upper end of the positioning column is used to pass through the hole on the PCB board to fix the PCB board.
[0014] As a further improvement, the rubber supporting arm is a plexiglass column.
[0015] The beneficial effect is: the utility model provides a new tool for gluing PCB boards. When gluing the PCB board, first, two adjacent electronic components on the PCB board are passed through the glue supporting piece, and the bottom of the PCB board is fixed on the supporting structure to avoid movement or shaking of the PCB board during the gluing process, which may affect the gluing quality. At the same time, the glue support is in contact with and fits the side surfaces of the two adjacent electronic components, and a special gluing area is determined between the two adjacent electronic components by the glue support. Compared with the existing technology that requires gluing to the larger gap between the two adjacent electronic components, the operator only needs to gluing towards the gluing space on the upper side of the glue support, which reduces the required amount of sealant and saves the operation time required for gluing. The sealant is filled between the upper side of the glue support and the two adjacent electronic components, which can stick to the two adjacent electronic components faster. After curing, the two adjacent electronic components are fixed, so that the two electronic components are connected and relied on each other by gluing, so that they are more stably and reliably fixed on the PCB base plate, ensuring that the electronic components on the PCB board will not be displaced or fall off due to vibration, impact, etc., thereby improving the reliability and stability of the PCB board and extending its service life.

[0020] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.
[0021] PCBs provide electrical connections for electronic components. During the use of electronic devices, they may be subject to various external impacts and vibrations. If the electronic components on the PCB are not properly secured, they can easily shift or fall off during vibration. Prior art techniques typically require applying glue between the electronic components soldered to the bottom of the PCB to ensure that the electronic components on the PCB remain stable during vibration. In particular, PCBs often have some taller electronic components with a relatively high center of gravity and relatively poor stability. This makes it even more necessary to apply glue so that adjacent electronic components can support each other, thereby more stably and reliably securing them to the PCB. However, the spacing between adjacent electronic components is large, and because the glue has a certain degree of fluidity, it is difficult to ensure that the glue is applied accurately, which can easily lead to unreliable fixing effects after the sealant cures. This often requires repeated application of glue, which is not only time-consuming and labor-intensive, but also requires an excessive amount of sealant, resulting in high costs. Therefore, the present invention provides a novel PCB glue application tool to address the aforementioned problems in the prior art.
[0022] The overall design concept of the PCB board gluing tool provided by the utility model is:
[0023] A tool for gluing PCBs comprises a base frame provided with a supporting structure for positioning and supporting the PCB. During gluing, the PCB is secured to and supported by the supporting structure to prevent movement or shaking of the PCB during gluing, which could affect the gluing quality. The base frame also includes a glue support member that can extend between two adjacent electronic components on the PCB and fit against the sides of the two components. The upper space between the electronic components on either side and the glue support member forms a gluing space for injecting glue.
[0024] The gap between two adjacent electronic components is determined as a special gluing area by the glue support. The operator only needs to apply glue towards the gluing space on the upper side of the glue support. Not only is the amount of glue required less, but gluing can also be performed at the position where gluing is required, ensuring that the two adjacent electrical components are bonded and fixed at the determined position, ensuring the reliability of the fixation. When the sealant flows on the glue support, it can contact the sides of the two adjacent electronic components more quickly, thereby sticking to the two adjacent electronic components more quickly, and achieving fixation between the two adjacent electronic components after curing. The electronic components are all glued together, and after the sealant is cured, the two adjacent electronic components can support and rely on each other, thereby being more stably and reliably fixed on the PCB baseboard, ensuring that the electronic components of the PCB board will not be displaced or fall off due to vibration, impact, etc., improving the reliability and stability of the PCB board, and extending its service life.
[0025] Especially for some electronic components on PCB boards that are taller and less stable, the glue support can determine a smaller, dedicated glue area in the larger gap between two adjacent electronic components, so that the two adjacent electronic components can be bonded while using a smaller amount of sealant.
[0026] Based on the above overall introduction to the present invention, a more specific embodiment is provided below:
[0027] This embodiment focuses on the detailed description of the rubber support component.
[0028] The glue supporting assembly includes a glue supporting piece, which extends between two adjacent electronic components on the PCB board and forms a glue application space for injecting glue with the upper space between the electronic components on both sides; the glue supporting piece is arranged on the base frame, and in order to further improve the reliability and stability of the PCB board after gluing, the glue supporting piece is arranged at a higher position on the base frame. When performing the gluing operation, the height of the glue supporting piece is close to the top of the electronic component, which is equivalent to one end of the electronic component being welded to the PCB board, and the other end near the top being bonded to the adjacent electronic component through sealant and more stably fixed on the PCB board. The glue supporting piece is arranged at different heights on the base frame, and correspondingly, after the glue supporting piece extends between two adjacent electronic components, it can form a glue application space for injecting glue at different heights on the side of the electronic component.
[0029] The glue support can be fixed on the base frame. When performing the glue application operation, the operator needs to move the PCB board so that two adjacent electronic components extend from both sides of the glue support. Figure 1-3 As shown, a more preferred method is that the rubber support member is slidably set on the base frame, specifically, the rubber support member is fixed on the mounting plate 5, and rubber support arms 6 are arranged at intervals on the mounting plate 5 to form a rubber support member extending into the adjacent electronic components. At this time, the operator only needs to fix the PCB board on the base frame, and then move the mounting plate 5 to make each rubber support member synchronously enter the gap between the corresponding electrical components, which is more labor-saving and convenient to operate.
[0030] In this embodiment, the glue support arm is an organic glass column. The organic glass column has good anti-sticking properties and is not easily adhered to by the sealant. It can be convenient for the glue support member to be removed after the glue application is completed and the sealant is cured. In addition, during the glue application process, a relatively flat surface is provided for the sealant, so that after the sealant is cured, the bottom of the cured sealant between the two adjacent electronic components is flat and more beautiful. In addition, the organic glass column has good transparency, which is convenient for observing the sealant during the glue application process, ensuring that the sealant can be accurately applied and the sides of the two adjacent electronic components are bonded together. Of course, the glue support arm can also be a plate-like structure such as an organic glass plate, or in other embodiments, a polycarbonate (PC) plate or a polycarbonate (PC) column can also be used.
[0031] Based on the above overall introduction to the present invention, a more specific embodiment is provided below:
[0032] like Figure 1-3 As shown, the base frame is L-shaped, including a horizontal bottom plate 1 and a vertical upright plate 2. The rubber support member is horizontally slidably arranged on the upright plate 2. A slot 4 is provided on the upright plate 2. The mounting plate 5 can be inserted into and slide through the slot 4, so that the rubber support member can be inserted between two adjacent electronic components. One end of the mounting plate 5 is provided with a plurality of columns along the extension direction of the slot 4. The columns are arranged at intervals to form a rubber support arm 6 that extends between two adjacent electronic components. The thickness of the mounting plate 5 is matched with the clearance of the slot 4, so that the mounting plate 5 can slide in the slot 4 along the extension direction of the rubber support arm 6. In addition, in order to ensure that the rubber support member does not slide out of the slot 4 and fall off during the sliding process, a structure for preventing it from falling off is provided at both ends of the mounting plate, such as columns higher than the slot directly fixed at both ends of the mounting plate, so as to prevent the mounting plate from falling off during the pushing and pulling process.
[0033] The mounting plate 5 is fixed with a stopper at the end of the glue supporting arm 6. The stopper is specifically a bent plate 8 fixed on the mounting plate 5 on one side and perpendicular to the glue supporting arm 6 on the other side. The bent plate 8 can be limited. When the mounting plate 5 is pulled out to the point where the bent plate 8 is against the vertical plate 2, it cannot be pulled out anymore, and the bending part of the bent plate 8 is flush with the end of the mounting plate 5. The end of the mounting plate 5 is arranged with a glue supporting arm 6. The side of the bent plate 8 facing away from the vertical plate 2 cooperates with the glue supporting arm 6 when gluing, and pushes the glue when gluing. The movable mounting plate 5 is moved to the bending plate 8 so that one side is attached to the electronic component 11. At this time, the glue supporting arm 6 is just extended between two adjacent electronic components 11. At this time, the bending plate 8 constitutes a glue blocking piece to block the gluing space from one side, which can resist the sealant during the gluing process and prevent the sealant from flowing to the vertical plate 2. It can not only further reduce the amount of sealant used, but also prevent the sealant from sticking to the vertical plate 2, avoiding the extra workload of the operator to clean the vertical plate 2 after the gluing is completed. More preferably, the bending plate is an organic glass bending plate. During the gluing, the sealant is not easy to adhere to the organic glass bending plate. After the gluing is completed, it is easier to remove the glue supporting piece from between the electronic components, and it is easy to clean, reducing the work intensity, and it can be reused. A handle 9 is provided at the end of the mounting plate 5, and the operator can use the handle 9 to easily pull the mounting plate 5.
[0034] Of course, the stopper can be a long plate fixed to the mounting plate. In other embodiments, glue stoppers can also be provided on both sides of the glue support member, such as providing another baffle. After the bent plate is attached to one side of the electronic component, the baffle is used to attach to the other side of the electronic component. The baffle is provided with a plug-in post, and the baffle is inserted into the socket on the bottom plate so that the baffle can be attached to the other side of the electronic component, thereby blocking both sides of the glue application space, providing a more precise glue application space, and further reducing the amount of sealant used.
[0035] In this embodiment, in order to ensure that the rubber supporting member can slide more smoothly, Figure 1-3 As shown, the slot 4 is provided with a guide plate for supporting and guiding. The guide plate is a support plate 12 provided at the slot. The support plate 12 extends a certain length along the length of the rubber support arm 6 to support the mounting plate 5 during its sliding process and guide the sliding direction of the mounting plate 5. In particular, the support plate 12 is arranged parallel to the base plate 1 so that the rubber support member can slide horizontally and extend between two adjacent electronic components 11.
[0036] More preferably, a long plate extending along the sliding direction of the rubber support is fixed on the back of the vertical plate, that is, on the side facing away from the PCB board. The long plate also serves as a guide plate to guide the mounting plate to slide in the slot, and the long plate and the support plate are respectively arranged at the notches on both sides of the slot, and the long plate is arranged on the upper side of the support plate. The rubber support slides between the long plate and the support plate and along the plate surface of the long plate and the support plate, so that the rubber support slides more smoothly on the vertical plate. And when the rubber support extends between two adjacent electronic components, the long plate can resist one end of the rubber support, so that the rubber support is relatively stable on the vertical plate. Preferably, in this embodiment, if Figure 1-3 As shown, the guide plate is an L-shaped plate 7 fixed to the vertical plate 2, with the shorter side of the L-shaped plate 7 fixed to the vertical plate 2, and the mounting plate 5 slides along the longer side of the L-shaped plate 7. In addition, the plate is provided with an escape groove for accommodating the handle 9 to prevent the handle from affecting the sliding of the rubber support.
[0037] In other embodiments, slots are not required on the vertical plate. Instead, rails are provided at the ends of the vertical plate for the mounting plate to slide on. A matching slider is provided at the bottom of the mounting plate. After the PCB is secured to the base plate, the mounting plate slides along the rails, allowing the rubber support members on the vertical plate to extend into the gaps between the corresponding electronic components. The different heights of the slots and rails on the vertical plate allow the rubber support members to operate at different heights. For example, for taller electronic components on the PCB, the slots or rails can be positioned higher on the vertical plate.
[0038] A clamp can be set on the bottom plate as a bearing structure to fix the PCB board on the bottom plate for gluing operation, ensuring that the PCB board will not move or shake during the gluing process. In this embodiment, it is preferred to set a positioning column 3 on the bottom plate, such as Figure 3 As shown, the upper end of the positioning post 3 can pass through the hole in the bottom 10 of the PCB board. The positioning post 3 is stepped, including a large diameter section and a small diameter section. The upper surface of the large diameter section supports the PCB board, while the position of the PCB board is restricted by the small diameter section. To improve the applicability of the PCB board gluing tool of the present invention, it is more preferable to provide a screw as a positioning member on the bottom plate, and configure a nut to fix the PCB board at different heights. The nut is mounted on the screw. The operator only needs to pass the hole in the PCB board over the screw and then rotate the nut to change the position of the nut on the screw to adjust the positioning height of the PCB board.
[0039] It should be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
[0040] In addition, the various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be based on the claims. Any equivalent structural changes made using the description and drawings of the present invention shall also be included in the scope of protection of the present invention.
