Description

Technical Field

[0001] This utility model relates to the field of dispensing and pressure holding, specifically, to a dispensing and pressure holding device. Background Technology

[0002] In modern industrial manufacturing, the dispensing and pressure-holding process is widely used in many industries such as electronics, automotive, and aerospace. Dispensing involves applying specific adhesive to a workpiece in precise amounts and locations to achieve multiple functions such as bonding, sealing, and fixing. The pressure-holding process is a crucial step in the dispensing process. It involves applying a certain pressure to the dispensed workpiece and maintaining it for a period of time to ensure that the adhesive fully fills the gaps between the workpieces, forming a uniform and stable adhesive layer, thereby achieving the ideal bonding or sealing effect and ensuring product quality and performance. Currently, one common pressure-holding method is to place the workpiece in a dedicated pressure-holding chamber. In this method, after the workpiece completes the dispensing process, it is transferred to the pressure-holding chamber, then a cover is placed on it, and pressure is applied to the workpiece through the cover to achieve the pressure-holding purpose. However, the existing pressure-holding operation process has a significant drawback.

[0003] After the workpiece is placed in the pressure chamber, it remains unsecured until the cover is closed. Industrial production environments are typically complex, with various external forces present, such as vibrations from production equipment, movement of personnel within the workshop, and airflow disturbances generated by material handling. These external forces can easily act on the unsecured workpiece, causing it to shift.

[0004] If the workpiece shifts before the cover plate closes, the pressure applied after the cover plate closes will deviate from its position. The accuracy of the pressure application position is crucial for the dispensing effect; an incorrect pressure application position will prevent the adhesive from distributing evenly as designed, potentially leading to uneven adhesive layer thickness and reduced bonding area. This not only affects the bonding strength and sealing performance between workpieces, reducing the overall product quality, but also results in defective products, increasing production costs and scrap rates, negatively impacting production efficiency and economic benefits.

[0005] Therefore, it is necessary to make further improvements to the existing technology. Summary of the Invention

[0019] According to one embodiment of the present invention, a connecting platform is provided at each of the opposite ends of the upper surface of the base plate, and both connecting platforms extend along the width direction of the base plate.

[0020] Both ends of the upper surface of the two connecting plates are provided with a connecting groove, and multiple locking components are provided on the bottom surface of the cover plate and are arranged opposite to the multiple connecting grooves one by one.

[0021] The locking member can switch between a third state and a fourth state. When the locking member is in the third state, the lower end of the locking member is locked in the connecting groove.

[0022] According to one embodiment of the present invention, each of the locking members includes a second slider, a locking part, and a second elastic member.

[0023] The cover plate has a second mounting surface on both sides, and both second mounting surfaces extend along the length of the cover plate. Both ends of the two second mounting surfaces have a second mounting groove. The second slider is located in the second mounting groove and can slide along the length of the second mounting groove.

[0024] The bottom surface of the second mounting groove is provided with a second through groove. The second mounting groove extends along the width direction of the cover plate and penetrates to the bottom surface of the cover plate. The upper end of the locking part is connected to the bottom surface of the second slider, and the lower end extends through the second through groove to the bottom surface of the cover plate.

[0025] The second mounting groove is provided with a second mounting hole on one side parallel to the second mounting surface.

[0029] According to an embodiment of this utility model, a dispensing and pressure-holding device allows for the orderly placement of multiple workpieces by distributing multiple placement slots at intervals along the length of a placement table. This facilitates batch processing, improves production efficiency, and the placement slots provide initial positioning of the workpieces, ensuring accurate placement. Multiple clamping components are mounted on the mounting table and correspond one-to-one with the placement slots, allowing for switching between a first state and a second state. Before the cover plate is closed after placing the workpiece, the clamping components are adjusted to the first state, with one end pressing against and fixing the workpiece. This prevents displacement of the workpiece due to external forces, ensuring accurate subsequent pressure-holding positioning, improving product quality, and reducing defective products. When the workpiece needs to be removed after pressure holding is completed, adjust the clamping device to the second state to move it away from the workpiece for easy operation. The cover plate is detachably connected to the base plate through multiple locking devices.

[0040] The following describes in detail, with reference to the accompanying drawings, an embodiment of the present invention: a dispensing and pressure-holding device.

[0041] Reference Figures 1 to 10 As shown, a dispensing and pressure-holding device according to an embodiment of the present invention includes a base plate 10, a placement platform 20, a mounting platform 30, multiple clamping members 31, and a cover plate 40. The base plate 10 is suitable for mounting on a machine base.

[0042] The placement platform 20 is located on the upper surface of the base plate 10. The placement platform 20 is provided with a plurality of placement slots 21, which are spaced apart along the length of the placement platform 20 for placing workpieces.

[0043] The mounting platform 30 is located on the upper surface of the base plate 10 and is arranged adjacent to the placement platform 20.

[0044] Multiple clamping members 31 are disposed on the mounting platform 30 and are arranged opposite to multiple placement slots 21. Multiple clamping members 31 can switch between a first state and a second state. When the clamping member 31 is in the first state, one end of the clamping member 31 presses and fixes the workpiece. When the clamping member 31 is in the second state, the clamping member 31 is away from the workpiece.

[0045] The cover plate 40 is disposed above the placement platform 20 and is detachably connected to the base plate 10 by multiple locking members 41. The bottom surface of the cover plate 40 is provided with multiple pressure plates 42, and the multiple pressure plates 42 and the multiple placement slots 21 are opposite to each other. When the cover plate 40 is closed on the base plate 10, the multiple pressure plates 42 press against the workpiece in the placement slot 21 to maintain pressure on the workpiece in the placement slot 21.

[0046] Based on the above, by distributing multiple placement slots 21 at intervals along the length of the placement table 20, multiple workpieces can be placed in an orderly manner, facilitating batch processing, improving production efficiency, and the placement slots 21 can perform preliminary positioning of the workpieces, ensuring the accuracy of the workpiece placement position. Multiple clamping components 31 are arranged on the mounting table 30 and are one-to-one with the placement slots 21, capable of switching between a first state and a second state. Before the cover plate 40 closes after placing the workpiece, the clamping component 31 is adjusted to the first state, with one end pressing against and fixing the workpiece, preventing displacement due to external forces, ensuring accurate subsequent pressure holding position, improving product quality, and reducing the generation of defective products. When the workpiece needs to be removed after pressure holding is completed, the clamping member 31 is adjusted to the second state to keep it away from the workpiece for easy operation. The cover plate 40 is detachably connected to the base plate 10 through multiple locking members 41. The bottom surface is provided with multiple pressure plates 42 that are one-to-one with the placement groove 21. When the cover plate 40 is closed on the base plate 10, the pressure plates 42 can press the workpiece in the placement groove 21 one-to-one, apply uniform and stable pressure to the workpiece, achieve a good pressure holding effect, ensure that the glue fully fills the gap of the workpiece, form a uniform and stable glue layer, and improve the bonding or sealing quality of the workpiece.

[0047] Preferably, in one embodiment of the present invention, each of the plurality of clamping members 31 includes a first slider 311, a connecting part 312, a clamping part 313, and a first elastic member 314.

[0048] Each mounting platform 30 is provided with a plurality of first mounting slots 32, and the plurality of first mounting slots 32 are arranged opposite to the plurality of placement slots 21. The first slider 311 is disposed in the first mounting slot 32 and can slide along the length direction of the first mounting slot 32.

[0049] The upper surface of the mounting platform 30 is provided with a plurality of first through grooves 33, which are connected to a plurality of first mounting grooves 32 one by one. The connecting part 312 is provided in the first through groove 33 and its lower end is connected to the first slider 311.

[0050] The clamping part 313 is located above the mounting platform 30, and its bottom surface is connected to the upper end of the connecting part 312; The first elastic element 314 is disposed between the first slider and the groove wall of the first mounting groove 32 away from the placement groove 21, and is used to apply elastic pressure to the first slider 311 so that one end of the clamping part 313 is clamped on the side of the workpiece.

[0051] Thus, by aligning the first mounting groove 32 with the placement groove 21 one-to-one, the first slider 311 slides along its length within the first mounting groove 32. This correspondence and guiding design enable the clamping member 31 to precisely operate the workpiece placed in the placement groove 21. The connecting part 312 passes through the first through groove 33 to connect the first slider 311 and the clamping part 313, ensuring the stability and coordination of the entire clamping member 31 structure during movement. It accurately converts the sliding of the first slider 311 into the clamping action of the clamping part 313 on the workpiece, achieving stable clamping of the workpiece side and effectively preventing the workpiece from shifting due to external force before pressure holding. The first elastic member 314 is disposed between the first slider 311 and the groove wall of the first mounting groove 32 away from the placement groove 21. It provides elastic pressure to the first slider 311, thereby ensuring that one end of the clamping part 313 is always clamped on the side of the workpiece.

[0052] Preferably, in one embodiment of the present invention, the upper surface of the other end of the clamping part 313 is provided with an insertion hole 3131, so that the clamping part 313 can be driven away from the workpiece after the robot arm is inserted.

[0053] Thus, in modern industrial production, automation is a key trend for improving production efficiency and reducing labor costs. The insertion hole 3131 allows the robotic arm to easily dock with the clamping part 313. The robotic arm can precisely insert into the insertion hole 3131 and drive the clamping part 313 away from the workpiece according to a preset program, eliminating the need for manual operation of the clamping part 31. This allows for seamless integration with the entire automated dispensing and pressure-holding production line, greatly improving the level of automation and continuity of production, and significantly enhancing overall production efficiency.

[0054] Preferably, in one embodiment of the present invention, one end face of the clamping part 313 is provided with an arc-shaped surface, and the arc-shaped surface is adapted to the side profile of the workpiece.

[0055] Thus, compared to flat clamping, the curved surface matches the side profile of the workpiece, greatly increasing the contact area between the clamping part 313 and the workpiece. According to the principle of friction, under a constant normal force, the larger the contact area, the greater the friction. This makes the clamping part 313 clamp the workpiece more securely, effectively preventing the workpiece from sliding or shifting due to external forces (such as vibration or airflow in the production environment) before pressure holding, ensuring the positional accuracy of the workpiece during the pressure holding process, and thus guaranteeing the quality of dispensing and pressure holding. Of course, the aforementioned curved surface can also be other shapes, and its specific design can be tailored to the outer contour of the workpiece being pressure held.

[0056] Preferably, in one embodiment of the present invention, the mounting platform 30 is provided with a first mounting surface 34 on the side away from the placement platform 20. The first mounting surface 34 is provided with a plurality of first mounting holes 341. The plurality of first mounting holes 341 are opposite to a plurality of first mounting grooves 32 and penetrate into the first mounting grooves 32. A plurality of first elastic members 314 are provided in the first mounting holes 341 in opposite directions. The first mounting surface 34 is provided with a detachable sealing strip 35. One end of the first elastic member 314 abuts against the first slider 311, and the other end abuts against the sealing strip 35.

[0057] Thus, a first mounting surface 34 is provided on the side of the mounting platform 30 away from the placement platform 20, and multiple first mounting holes 341 are formed, one-to-one with the first mounting grooves 32 and penetrating into the first mounting grooves 32, providing a precise mounting position for the first elastic element 314. This design allows each first elastic element 314 to be accurately placed in a specific first mounting hole 341, forming a good fit with the first slider 311, ensuring that the first elastic element 314 can stably and reliably apply elastic pressure to the first slider 311, thereby ensuring the clamping effect of the clamping part 313 on the workpiece.

[0058] Meanwhile, since the first elastic element 314 is located within the first mounting hole 341 and is fixed by a detachable sealing strip 35, when the first elastic element 314 is damaged or requires adjustment of its elastic force, the operator can easily remove the sealing strip 35 to replace or adjust the first elastic element 314. This eliminates the need for extensive disassembly of the entire mounting platform 30 or clamping component 31, significantly shortening maintenance time, reducing maintenance costs, and improving the maintainability and service life of the device.

[0059] Preferably, in one embodiment of the present invention, a connecting platform 11 is provided at each of the opposite ends of the upper surface of the base plate 10, and both connecting platforms 11 extend along the width direction of the base plate 10.

[0060] Both ends of the upper surface of the two connecting platforms 11 are provided with a connecting groove 12, and multiple locking elements 41 are provided on the bottom surface of the cover plate 40 and are arranged opposite to the multiple connecting grooves 12 one by one.

[0061] The locking member 41 can switch between a third state and a fourth state. When the locking member 41 is in the third state, the lower end of the locking member 41 is locked in the connecting groove 12. When the locking member 41 is in the fourth state, the lower end of the locking member 41 can be disengaged from the connecting groove 12.

[0062] Thus, by providing connecting platforms 11 extending along the width direction at opposite ends of the base plate 10, and opening connecting grooves 12 at both ends of the upper surface of the connecting platforms 11, each corresponding to a plurality of locking elements 41 provided on the bottom surface of the cover plate 40, this design allows the locking elements 41 to be precisely inserted into the corresponding connecting grooves 12 when the cover plate 40 is closed onto the base plate 10. When the locking elements 41 are locked in the connecting grooves 12 in the third state, a reliable connection is provided between the cover plate 40 and the base plate 10, effectively preventing the cover plate 40 from shifting or loosening during the pressure holding process due to factors such as glue reaction force or external vibration, ensuring that the pressure plate 42 on the bottom surface of the cover plate 40 can always accurately press against the workpiece in the placement groove 21, and ensuring the stability and reliability of the pressure holding effect.

[0063] Preferably, in one embodiment of the present invention, each of the locking members 41 includes a second slider 411, a locking part 412, and a second elastic member 413.

[0064] The cover plate 40 has a second mounting surface 43 on both sides. Both second mounting surfaces 43 extend along the length of the cover plate 40. Both ends of the two second mounting surfaces 43 have a second mounting groove 431. The second slider 411 is located in the second mounting groove 431 and can slide along the length of the second mounting groove 431.

[0065] The bottom surface of the second mounting groove 431 is provided with a second through groove 44. The second mounting groove 431 extends along the width direction of the cover plate 40. The second through groove 44 penetrates to the bottom surface of the cover plate 40. The upper end of the locking part 412 is connected to the bottom surface of the second slider 411, and the lower end extends through the second through groove 44 to the bottom surface of the cover plate 40.

[0066] The second mounting groove 431 has a second mounting hole 45 on one side parallel to the second mounting surface. One end of the second elastic member 413 is located in the second mounting hole 45, and the other end abuts against the side of the second slider 411. The connecting groove 12 has a protrusion 13 on one side wall near the middle of the connecting platform 11. The locking part 412 has a slot 4121 on the side opposite to the protrusion 13. When the locking member 41 is in the third state, the lower end of the locking part 412 is inserted into the connecting groove 12, and the protrusion 13 is held in the slot 4121.

[0067] Thus, when the locking member 41 is in the third state, the lower end of the locking part 412 is inserted into the connecting groove 12, and the protrusion 13 on the side wall of the connecting groove 12 precisely engages with the slot 4121 on the side of the locking part 412. This engaging structure forms a mechanical interlock, which can effectively prevent the cover plate 40 from shifting in the horizontal and vertical directions. During the pressure holding process, even if affected by the reaction force of the glue, external vibration, etc., the cover plate 40 can be firmly covered on the base plate 10, ensuring that the pressure plate 42 accurately presses the workpiece, ensuring a stable and reliable pressure holding effect, and improving product quality. One end of the second elastic member 413 is fixed in the second mounting hole 45, and the other end abuts against the side of the second slider 411. During the locking process, the second elastic member 413 always applies elastic pressure to the second slider 411, so that the locking part 412 is tightly engaged with the protrusion 13 in the connecting groove 12. This elastic assistance further enhances the stability of the locking, avoids connection failure caused by component wear or loosening, and extends the service life of the device.

[0068] Meanwhile, since the second slider 411 is located in the second mounting groove 431 and can slide along its length, during production, the position of the locking part 412 can be controlled by using a robot to clamp, push or release the outer side of the second slider 411, thereby realizing the locking and unlocking operation of the locking part 41.

[0069] Preferably, in one embodiment of the present invention, the second slider 411 is provided with a limiting groove 4111, the limiting groove 4111 extends along the length direction of the second slider 411, the bottom surface of the cover plate 40 is provided with a third mounting hole 46, the third mounting hole 46 is disposed opposite to the limiting groove 4111, a limiting post 47 passes through the mounting hole, the upper end of the limiting post 47 extends into the limiting groove 4111, and is used to limit the stroke of the second slider 411.

[0070] Thus, the cooperation between the limiting post 47 and the limiting groove 4111 provides a stable guiding and constraining effect for the second slider 411. During the movement of the second slider 411, the limiting post 47 remains within the limiting groove 4111, preventing the second slider 411 from moving excessively.

[0071] Preferably, in one embodiment of the present invention, a quick-release plate 14 is further included, which is detachably disposed on the upper surface of the base plate 10, and the mounting platform 30 and the placement platform 20 are both disposed on the upper surface of the quick-release plate 14.

[0072] Thus, because the quick-release plate 14 can be quickly disassembled, when different workpieces need to be held under pressure or when the mounting platform 30, placement platform 20 or their components malfunction, since the mounting platform 30 and placement platform 20 are individual components, they need to be disassembled for repair or replacement, which affects production. However, by setting the quick-release plate 14, when the mounting platform 30 or placement platform 20 malfunctions, the components can be quickly disassembled directly through the quick-release plate 14 and replaced with new components, without having to disassemble and inspect the entire structure one by one. This helps to shorten maintenance time and avoid affecting production efficiency.

[0073] Preferably, in one embodiment of the present invention, a limiting platform 15 is provided on the placement platform. The limiting platform 15 is located on the side of the placement groove 21 away from the mounting platform 30, and is used to cooperate with the clamping member 31 to clamp the workpiece in the placement groove 21.

[0074] Thus, the limiting platform 15 and the clamping member 31 cooperate to clamp the workpiece from both sides. The clamping member 31 applies pressure from one side, while the limiting platform 15 provides a reaction force from the other side, forming a stable clamping system. This bidirectional clamping method can effectively fix the workpiece and prevent it from moving or shaking during the pressure holding process due to the reaction force of the glue, external vibration, or other factors. This ensures that the pressure plate 42 can always accurately press the workpiece at the specified position, guaranteeing the stability and reliability of the pressure holding effect.
