Description

Pressure maintaining mechanism and device

Technical Field

The present application relates to parts assembling equipment, and more particularly, to a pressure maintaining mechanism and a pressure maintaining device.

Background

In the 3C (Computer, communication, and Consumer Electronics (consumer electronics) electronic industry, the assembly of parts of a product may be achieved by welding, gluing, riveting, etc. processes. When two parts are glued, glue can be dispensed on one of the parts, and then the other part is placed on the glued part. The two parts are then pressed together by pressing and holding the pressure on the other part for a period of time using a pressure holding device.

When the existing most pressure maintaining devices are used for maintaining pressure, operators need to rely on balancing weights to adjust the pressure of the pressure maintaining, and balancing weights with different weights are stacked according to the pressure required by the pressure maintaining. Because the pressure precision requirement is higher when keeping pressure, when carrying out the regulation of the pressurize power of higher precision, need use several grams, even the balancing weight of a few tenths of a gram. Because the volume of the balancing weight of a few grams or a few tenths of a gram is too small, the balancing weight is easy to lose. Once the balancing weight is lost, the balancing weight is required to be overlapped again for re-balancing, so that the workload of operators in pressure maintaining operation is increased, and the operators are easy to fatigue. Therefore, the existing pressure maintaining device has the problem that the balancing weight is easy to lose, so that the workload of pressure maintaining operation is increased.

Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The specific meaning of the terms in this application will be understood by those of ordinary skill in the art in a specific context.

As shown in fig. 1, in an embodiment, a dwell mechanism 1 is provided for dwell a product 2 to be dwell, comprising: a first moving part 10, a second moving part 11, a bracket 12 and an adjusting member 13. The first moving member 10 may abut against the product 2 to be pressurized. The second moving part 11 and the first moving part 10 are movably connected. The bracket 12 and the second moving member 11 are movably connected. The adjusting piece 13 is connected with the bracket 12, and the adjusting piece 13 can be adjusted to enable one end of the adjusting piece 13 to prop against the second moving part 11, so that the second moving part 11 elastically props against the first moving part 10, and the second moving part 11 elastically props against the bracket 12, so that the first moving part 10 generates a pressure maintaining force on the product 2 to be maintained. The connection between the adjusting member 13 and the bracket 12 may be fixed or detachable.

By providing the first moving part 10, the second moving part 11, the bracket 12 and the adjusting member 13. The first moving part 10 can be abutted against the product 2 to be pressurized. The second moving part 11 and the first moving part 10 are movably connected with the bracket 12. The adjusting member 13 is connected to the bracket 12. The adjusting member 13 is adjusted to make one end of the adjusting member 13 abut against the second moving member 11, so that the second moving member 11 elastically abuts against the first moving member 10, and the second moving member 11 elastically abuts against the bracket 12. Since the second moving member 11 elastically abuts against the first moving member 10, an elastic force can be generated, and when the elastic force acts on the first moving member 10, the first moving member 10 can generate a holding force on the product 2 to be held in pressure together with the gravity of the first moving member 10 itself. Therefore, after one end of the adjusting member 13 abuts against the second moving part 11, the pressure maintaining force can be adjusted by adjusting the adjusting member 13 without additionally arranging a balancing weight to adjust the pressure maintaining force, and the adjusting member 13 is connected with the bracket 12, so that the pressure maintaining operation is not easy to lose, i.e. the workload of pressure maintaining operation is not increased because the balancing weight is easy to lose.

As shown in fig. 1, the product 2 to be pressurized may be composed of a part a and a part B, and after the part B is coated with the adhesive, the part a is placed on the surface of the part B coated with the adhesive. The product 2 to be held under pressure is located below the first moving member 10 (for example, the product 2 to be held under pressure may be placed on a stage (not shown) below the first moving member 10). After the first moving part 10 moves downwards to abut against the part a, the pressure maintaining operation can be performed on the assembly of the part a and the part B. The adjusting member 13 may be a micrometer or a screw. The adjusting member 13 may be fixed to the bracket 12, and the adjusting member 13 may include a moving head 130, and the moving head 130 may move relative to the bracket 12 and rigidly abut against the second moving member 11. The bottom end of the first moving member 10 may abut against the product 2 to be pressure-maintained. The bottom end of the adjusting member 13 (e.g., the bottom end of the moving head 130) may abut against the top left side of the second moving member 11, and the top right side of the second moving member 11 may elastically abut against the top end of the first moving member 10. The adjusting member 13 may be connected to the top end of the support 12, and the bottom end of the second moving member 11 may elastically abut against the bottom end of the support 12.

As shown in fig. 1, the second moving part 11 elastically abuts against the first moving part 10, that is, the second moving part 11 elastically deforms when abutting against the first moving part 10 to generate elastic force, and the elastic force generated when the second moving part 11 and the first moving part 10 elastically abut against each other may be generated by the elastic deformation of the second moving part 11 or the first moving part 10 itself, or may be generated by providing an elastic part (such as the first elastic part 14) between the second moving part 11 and the first moving part 10, as described later in this embodiment. The sum of the elastic force generated when the second moving part 11 and the first moving part 10 elastically prop against each other and the gravity of the first moving part 10 is the holding force. The dwell force remains substantially unchanged during the dwell operation.

As shown in fig. 1, similarly, the elastic force generated when the second moving member 11 elastically abuts against the bracket 12 may be generated by elastic deformation of the second moving member 11 or the bracket 12 itself, or may be generated by an elastic member (e.g., the second elastic member 15) disposed between the second moving member 11 and the bracket 12 as described later in this embodiment. The second moving part 11 elastically abuts against the bracket 12 to generate elastic deformation so as to match the elastic deformation generated when the second moving part 11 abuts against the first moving part 10, so that the movement of the first moving part 10 and the movement of the second moving part 11 can be synchronous.

As shown in fig. 1, the pressure maintaining mechanism 1 preferably further comprises a first elastic component 14 and a second elastic component 15, wherein the first elastic component 14 is located between the first moving component 10 and the second moving component 11, the second elastic component 15 is located between the second moving component 11 and the bracket 12, and the adjusting piece 13 can enable one end of the adjusting piece 13 to abut against the second moving component 11, and further push the second moving component 11 to abut against the first elastic component 14 and the second elastic component 15, so that the first elastic component 14 is elastically deformed to adjust the pressure maintaining force. The first elastic member 14 may be located between the tip of the first moving member 10 and the right side of the tip of the second moving member 11. The second elastic member 15 may be located between the bottom end of the second moving member 11 and the bottom end of the bracket 12. The first elastic member 14 and the second elastic member 15 may be compression springs. The first elastic member 14 and the second elastic member 15 may be disposed parallel to each other.

As shown in fig. 2, the number of the first elastic members 14 and the number of the second elastic members 15 are two, and the two first elastic members 14 are disposed apart from each other. For example, the two first elastic members 14 may be disposed parallel to each other. The two second elastic members 15 are disposed apart from each other. For example, the two second elastic members 15 may be disposed parallel to each other. The number of the first elastic members 14 and the second elastic members 15 may be other values. When the second moving member 11 is a plate-like member, the two first elastic members 14 are disposed apart from each other, and it is less likely to cause the second moving member 11 to be unstable against the first elastic members 14 than when a single elastic member is used. Similarly, when the second moving member 11 is a plate-like member, the two second elastic members 15 are disposed apart from each other, and it is less likely to destabilize when the second moving member 11 abuts against the second elastic member 15 than when a single elastic member is used.

As shown in fig. 2, the central axis of the moving head 130 of the adjusting member 13 may be parallel to the central axis of the first elastic member 14, and the central axis of the moving head 130 may be parallel to the central axis of the second elastic member 15. When the number of first elastic members 14 is two, the projection of the moving head 130 on the first moving member 10 (the first riser 100 as described later in the examples) may be located between the two projections of the two first elastic members 14 on the first riser 100. When the number of the second elastic members 15 is two, the central axes of the moving head 130 may be parallel to the central axes of both the second elastic members 15 (i.e., three central axes may be coplanar). The projection of the moving head 130 at the bottom end of the support 12 (e.g., the base 122 in the following of the implementation) may be located between the two second elastic members 15. Defining a median plane (not shown) perpendicular to the bottom end of the support 12 (e.g., to the bottom plate 122 in the vertical implementation and to the side of the first riser 100 and passing through the midpoint of the distance between the two second elastic members 15, the two first elastic members 14 and the two second elastic members 15 may be symmetrically disposed about the median plane. The mid-plane may pass through a central axis of the moving head 130.

The stiffness coefficient of the first elastic member 14 may be smaller than that of the second elastic member 15 so that the elastic force between the first and second moving members 10 and 11 and the elastic force between the second moving member 11 and the bracket 12 can be adjusted, respectively. Since the holding force is the sum of the weight of the first moving part 10 itself and the elastic force generated by the deformation of the first elastic part 14 and the weight of the first moving part 10 itself is larger than the elastic force generated by the deformation of the first elastic part 14, only a small elastic force is required between the first moving part 10 and the second moving part 11 (generally at 10 ^-3 N to 10 ^-2 N), the total pressure maintaining force can be accurately adjusted, so that the first elastic component 14 with small stiffness coefficient can provide the needed elastic force with higher precision. Because the second elastic member 15 needs to support the weight of the first moving member 10 and the second moving member 11 and support the adjusting pressure generated by the adjusting member 13, the second elastic member 15 with a large stiffness coefficient is used, so that the second elastic member 15 is prevented from being deformed too much to be easily failed.

As shown in fig. 3, preferably, the first moving member 10 includes a first riser 100, a first traverse plate 101, and a pressing head 103, one end of the first riser 100 is connected to one end of the first traverse plate 101, the other end of the first traverse plate 101 is connected to one end of the pressing head 103, the other end of the pressing head 103 is movable against the product 2 to be held in pressure, the first riser 100 and the second moving member 11 are movably connected, and the first elastic member 14 is located between the other end of the first riser 100 and the second moving member 11. One end of the first riser 100 and one end of the first cross plate 101 may be connected by welding, cementing, or an integral molding. The first riser 100 and the pressing head 103 may each be disposed perpendicular to the first cross plate 101. The first riser 100 and the first cross plate 101 may each have a rectangular parallelepiped shape. The right side bottom end of the first riser 100 may be connected to the left side of the first cross plate 101.

As shown in fig. 3, the top surface of the pressing head 103 may be connected to the bottom surface of the first cross plate 101 at a position distant from the first riser 100. The bottom surface of the pressing head 103 may abut against the top surface of the product 2 to be pressure-maintained. The pressing head 103 may be formed by stacking a plurality of (e.g., three) rectangular parallelepiped blocks in order, and of the plurality of rectangular parallelepiped blocks, the volume of the rectangular parallelepiped block in contact with the product 2 to be held pressure may be minimum and the volume of the rectangular parallelepiped block connected to the first traverse plate 101 may be maximum.

As shown in fig. 3, the first elastic member 14 may be located between the top surface of the first riser 100 and the top bottom surface right side of the second moving member 11. At the other end (e.g., the top surface) of the first riser 100 may be disposed a first guide post 104, and the first elastic member 14 may be sleeved on the first guide post 104. The first guide post 104 is used to secure the first elastic member 14. The first guide posts 104 may be disposed in one-to-one correspondence with the first elastic members 14. The length of the first guide post 104 is smaller than the original length of the first elastic member 14, so as not to influence the elastic force generated by the first elastic member 14.

As shown in fig. 3, one end of the pressing head 103 is detachably connected to the other end of the first cross plate 101. One end of the pressing head 103 and the other end of the first cross plate 101 can be detachably connected by screwing or clamping. Because in actual production, the specifications of the product 2 to be pressure-maintained may be more than one, different products 2 to be pressure-maintained need different pressing heads 103 to be matched, and after the pressing heads 103 are detachably connected with the first transverse plate 101, the different pressing heads 103 can be conveniently replaced.

As shown in fig. 3, the bottom surface of the other end of the pressing head 103 and the upper surface of the product 2 to be held in pressure are substantially the same in size. For example, the bottom surface of the pressing head 103 and the upper surface of the product 2 to be held pressure may each be rectangular and have substantially the same size. The bottom surface of the other end of the pressing head 103 and the upper surface of the product 2 to be pressurized are approximately the same in size, so that the upper surface of the product 2 to be pressurized can be uniformly pressurized, and the product 2 to be pressurized is prevented from being crushed due to the fact that the bottom surface of the other end of the pressing head 103 is too small (too sharp).

As shown in fig. 4, preferably, the second moving part 11 (refer to fig. 3 for the second moving part 11) includes a second riser 110 and a second traverse 111, the second riser 110 and the second traverse 111 are connected, the second riser 110 and the first riser 100 are movably connected, and the second riser 110 and the bracket 12 are movably connected. The second riser 110 and the second cross plate 111 may each have a rectangular parallelepiped shape. The second riser 110 and the second cross plate 111 may be connected by welding, gluing or integrally forming. The second riser 110 may be disposed perpendicular to the second cross plate 111. For example, the right side top of the second riser 110 may be connected with the left side of the second cross plate 111. One end of the adjusting member 13 may abut against the second riser 110, the second transverse plate 111 is located above the first riser 100, the first elastic member 14 is located between the second transverse plate 111 and the other end of the first riser 100, and the second elastic member 15 is located between the second riser 110 and the bracket 12.

As shown in fig. 4, the bottom end of the moving head 130 of the adjusting member 13 may abut against the middle position of the top surface of the second riser 110, and the bottom surface of the second transverse plate 111 may be parallel to the top surface of the first riser 100. The first elastic member 14 may be located between the right side of the bottom surface of the second cross plate 111 and the top surface of the first riser 100. The second resilient member 15 may be located between the bottom surface of the second riser 110 and, for example, the bottom end of the bracket 12. The first riser 100 and the second riser 110 may be disposed parallel to each other, and the first transverse plate 101 and the second transverse plate 111 may be disposed parallel to each other.

As shown in fig. 4, the second moving member 11 (refer to fig. 3 for the second moving member 11) preferably includes a stopper 112. Specifically, the second riser 110 includes a stopper 112, the stopper 112 is located below the first elastic member 14, the first riser 100 is located between the stopper 112 and the first elastic member 14, and the first riser 100 can be stopped from moving in a direction away from the first elastic member 14 by being blocked by the stopper 112. For example, the stop 112 may block the first riser 100 from moving vertically downward. The stopper 112 is a protrusion extending laterally along the second riser 110. The stopper 112 may be a cylinder, and the stopper 112 may be disposed perpendicular to the bottom end of the right side surface of the second riser 110. The stopper 112 and the second riser 110 may be connected by plugging or integrally molding. The number of the stop portions 112 is two, and the two stop portions 112 are disposed apart from each other. The two stops 112 may be symmetrically disposed about the aforementioned mid-plane. The two stoppers 112 may be disposed parallel to each other. The two stops 112 are spaced apart from one another and are less likely to destabilize the first riser 100 when blocked by the stops 112 than if a single stop were used.

Preferably, when the first riser 100 is blocked by the stopper 112, the elastic force generated by the first elastic member 14 is zero. When the first riser 100 is blocked by the blocking portion 112, the elastic force generated by the first elastic member 14 is zero, so that the first elastic member 14 is in an original length state when not in use (i.e., when pressure maintaining is not needed), that is, the first elastic member 14 is neither stretched nor compressed when not in use, so as to avoid unnecessary deformation of the first elastic member 14 and reduce the service life. For example, the stop portion 112 may be disposed at a suitable position of the second riser 110, so that when the first riser 100 is blocked by the stop portion 112, the first elastic member 14 may be just in an original length state, and both ends thereof respectively abut against the right side of the bottom surface of the second transverse plate 111 and the top surface of the first riser 100.

As shown in fig. 5, the bracket 12 (see fig. 4 for the bracket 12) preferably includes a top plate 120, a side plate 121, and a bottom plate 122, and the top plate 120 and the bottom plate 122 are respectively connected to both ends of the side plate 121. The adjusting member 13 is connected to the top plate 120, the second riser 110 is located between the top plate 120 and the bottom plate 122, the second riser 110 is movably connected to the side plate 121, and the second elastic member 15 is located between the second riser 110 and the bottom plate 122. The top plate 120, the side plates 121, and the bottom plate 122 may each have a rectangular parallelepiped shape. The top plate 120 and the bottom plate 122 may be connected to both ends of the side plate 121 by welding, gluing or integrally molding. The top plate 120 may be connected to the top of the side plate 121, and the bottom plate 122 may be connected to the bottom of the side plate 121.

As shown in fig. 5, the top plate 120 and the bottom plate 122 may be disposed parallel to each other and perpendicular to the side plate 121, and the side plate 121 may be disposed parallel to the first riser 100 and the second riser 110. The bottom left portion of the top plate 120 may be connected to the top surface of the side plate 121.
