Further, referring to fig. 1, fig. 1 is a schematic structural diagram of an adaptive pressing mechanism 100 according to some embodiments of the present application, wherein the adaptive pressing mechanism 100 can cooperate with a pressing device to perform a pressing process on a pressed product.

The pressing assembly 10 is disposed on one side of the mounting assembly 20, and the floating joint 30 is disposed on the other side of the mounting assembly 20. Namely, the pressing component 10 and the floating joint 30 are respectively disposed on two opposite sides of the mounting component 20, in other words, the floating joint 30 is disposed on a side of the mounting component 20 away from the pressing component 10.
Further, the substrate 40 is disposed on a side of the floating joint 30 away from the mounting assembly 20, i.e., the substrate 40 is disposed above the floating joint 30 and spaced apart from the floating joint 30. The cylinder 50 is disposed on a side of the substrate 40 away from the mounting assembly 20, and a cylinder axis of the cylinder 50 penetrates through the substrate 40 and is connected to the floating joint 30. It will be appreciated that the cylinder shaft of the cylinder 50 is connected to the floating joint 30, and the floating joint 30 is driven to move when the cylinder 50 is operated, so that the mounting assembly 20 and the pressing assembly 10 perform linear movement for performing the pressing operation.
Specifically, the pressing assembly 10 is fixedly connected with the mounting assembly 20, so that the pressing assembly 10 and the mounting assembly 20 can perform synchronous movement.

It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiment of the present application are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.
The self-adaptive pressing mechanism 100 provided by the embodiment of the application drives the floating joint 30 to move through the cylinder shaft movement of the cylinder 50, so as to provide an acting force for the installation component 20 and the pressing component 10, and thus the pressing component 10 can perform pressing operation on a pressed product.
In the research of the applicant, in the conventional pressing device, the pressing head of the pressing device is generally in hard contact with the pressed product during pressing, so that when the pressing head is not parallel to the pressing surface of the pressed product, the pressure applied to the pressed product by the pressing device is not uniformly distributed on the pressed product, thereby causing poor pressing.
Based on the technical problems, the applicant further researches and discovers that when the pressure head is in contact with a pressed product, if the pressure head can automatically adjust the angle of the pressure head according to the pressed product, the parallelism error of the pressing surface is compensated, so that the pressure head can provide uniform pressing force for the pressed product, and the pressing yield is improved.
Based on this, some embodiments of the present application further provide a pressing component 10, and this pressing component 10 can automatically compensate the pressing plane parallelism error when performing the pressing operation on the pressed product, so as to realize the uniform stress of the pressed product, thereby improving the yield of the pressing production.
Specifically, referring to fig. 2 and fig. 3 in combination, fig. 2 is a schematic structural diagram of a pressing assembly 10 in some embodiments of the present application, and fig. 3 is a schematic structural diagram of the pressing assembly 10 in some embodiments of the present application, where the pressing assembly 10 may substantially include a fixing structure 11, a pressing head 12 and a connecting structure 13. Wherein, fixed knot constructs 11 and installation component 20 fixed connection, and pressure head 12 sets up in the one side that fixed knot constructs 11 and keep away from installation component 20, and connection structure 13 connects fixed knot and constructs 11 and pressure head 12. The mounting assembly 20 may include a mounting plate, and the fixing structure 11 is fixedly connected to the mounting plate to fixedly connect the pressing assembly 10 and the mounting assembly 20.
It is understood that the fixing structure 11 and the mounting component 20 can be fixedly connected by screws, for example, screw holes are formed at corresponding positions of the fixing structure 11 and the mounting component 20, and then the fixing structure is screwed tightly. Of course, in other embodiments, the fixing structure 11 and the mounting assembly 20 may be fixedly connected by a fixing method such as a bolt, a snap, and the like.
Further, the connecting structure 13 generally includes a movable member 131 and an elastic member 132, the movable member 131 is disposed through the fixed structure 11, and the elastic member 132 connects the movable member 131 and the pressing head 12, so as to realize the angle adjustment of the pressing head 12 when pressing.
Specifically, a side of the fixing structure 11 close to the mounting assembly 20 is provided with a groove (to be further described later), and the pressing head 12 is provided on a side of the fixing structure 11 far from the groove. The elastic member 132 is disposed between the fixing structure 11 and the pressing head 12, and two ends of the elastic member 132 respectively abut against the fixing structure 11 and the pressing head 12, so that the pressing head 12 and the pressed product are in elastic contact when performing the pressing operation, the pressing head 12 can automatically adjust the angle of the pressing head 12 according to the pressed product, and further compensate the parallelism error of the pressing surface, so that the pressing head 12 can provide an even pressing force for the pressed product, and the pressing yield is improved. The movable element 131 is inserted through the fixed structure 11 in the direction of the bottom wall of the groove toward the ram 12, in other words, the movable element 131 extends along the bottom wall of the groove toward the ram 12 and penetrates the bottom wall of the groove.
Referring to fig. 4 and 5 in combination, fig. 4 is a schematic cross-sectional view taken along a-a direction in fig. 2, and fig. 5 is a schematic structural view of a fixing structure 11 according to some embodiments of the present disclosure, where the fixing structure 11 generally includes a fixing portion 111 and a connecting portion 112. The fixing portion 111 is protruded from a side of the connecting portion 112 close to the mounting component 20, and a groove 113 is defined by the fixing portion 111 and the connecting portion 112. It will be appreciated that the recess 113 opens towards the mounting assembly 20; in other words, the bottom wall of the groove 113 is close to the elastic member 132, and the opening of the groove 113 is distant from the elastic member 132.
Further, a first through hole 114 is formed in the bottom wall of the groove 113, the first through hole 114 penetrates through the fixed structure 11 in the direction from the bottom wall of the groove 113 to the pressing head 12, and the movable element 131 penetrates through the first through hole 114. Specifically, the fixing portion 111 of the fixing structure 11 is used to be fixed with the mounting component 20 to position the press-fit component 10, that is, the fixing portion 111 of the fixing structure 11 and the mounting component 20 can be fixed by screwing.
Further, the fixing portion 111 of the fixing structure 11 is protruded from the connecting portion 112 to form a groove 113, and the groove 113 provides a mounting space for the movable member 132 on one hand to facilitate mounting; on the other hand, when the pressing assembly 10 presses the product, the movable member 132 moves back and forth along the first through hole 114, and the groove 113 provides a moving space for the movable member 132. It will be appreciated that the maximum height of the movable member 132 projected from the bottom wall of the recess 113 in the direction of the extension of the axis of the first through hole 114 during the expansion and contraction of the movable member 132 does not exceed the depth of the recess 113.
Referring to fig. 6 in combination, fig. 6 is a schematic structural diagram of the movable element 131 according to some embodiments of the present disclosure, and the movable element 131 generally includes a position-limiting portion 1311 and a main body portion 1312. The position-limiting portion 1311 is disposed at one end of the main body 1312 close to the bottom wall of the groove 113, and the elastic member 132 is connected at one end of the main body 1312 far from the bottom wall of the groove 113. It can be understood that, when the movable element 132 moves back and forth along the first through hole 114, the position-limiting portion 1311 may protrude from the bottom wall of the groove 113 along the axial extension of the first through hole 114.
Further, the cross-sectional area of the stopper portion 1311 in the axial extending direction of the first through hole 114 gradually increases, in other words, the area of the end surface of the stopper portion 1311 away from the main body portion 1312 is larger than the area of the end surface of the stopper portion 1311 close to the main body portion 1312. Specifically, the cross section of the stopper 1311 in the direction a-a is substantially trapezoidal, with the lower base (i.e., the longer base) of the trapezoid being away from the main body 1312 and the upper base (i.e., the shorter base) of the trapezoid being connected to the main body 1312.
It is to be understood that the terms "first", "second" and "third" in the embodiments of the present application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature.
Referring to fig. 4-6, the first through hole 114 generally includes a first hole section 1141 and a second hole section 1142, the position-limiting portion 1311 is partially received in the first hole section 1141, and the main body portion 1312 is partially received in the second hole section 1142. Specifically, the first hole section 1141 is substantially matched with the limiting portion 1311, and the second hole section 1142 is substantially matched with the main body portion 1312. In other words, the area of the end surface of the first bore section 1141 away from the main body portion 1312 is larger than the area of the end surface of the first bore section 1141 close to the main body portion 1312. It will be appreciated that the diameter of the first bore section 1141 is greater than the diameter of the second bore section 1142, and the diameter of the first bore section 1141 increases progressively along the axial extent of the first through bore 114.
Further, the first bore section 1141 has a generally trapezoidal cross-section along the direction a-a, with the lower base (i.e., the longer base) of the trapezoid facing away from the body portion 1312 and the upper base (i.e., the shorter base) of the trapezoid connecting the body portion 1312. The first hole section 1141 is surrounded to form a first inclined surface 1143, the side surface of the limiting portion 1311 close to the first inclined surface 1143 is surrounded to form a second inclined surface 1313, and the inclination angles of the first inclined surface 1143 and the second inclined surface 1313 are substantially the same. Specifically, the first inclined surface 1143 and the second inclined surface 1313 are at the same angle to a plane perpendicular to the axis of the first through hole 114.
Further, the included angle between the first inclined surface 1143 and the second inclined surface 1313 and the plane perpendicular to the axis of the first through hole 114 is generally 15 to 75 degrees, and may be, for example, 15 degrees, 30 degrees, 45 degrees, 60 degrees, 75 degrees, and the like. It can be understood that, when the pressing assembly 10 provided by the embodiment of the present application is in the initial state (i.e. when a product is not pressed), the position accuracy of the pressing head 12 in the initial state of the pressing assembly 10 can be ensured by providing the first inclined surface 1143 and the second inclined surface 1313 which are matched with each other.
It should be noted that, in the pressing assembly 10 provided in some embodiments of the present application, the pressing head 12 of the pressing assembly 10 can automatically compensate for the parallelism error of the pressing surface during the pressing operation, so as to achieve uniform stress on the pressed product. Referring to fig. 7, fig. 7 is a schematic view illustrating a structural state of the pressing assembly 10 according to some embodiments of the present application when the pressing head 12 presses the pressed product, a force between the pressing head 12 and the pressed product acts on the elastic element 132, so as to push the movable element 131 out in a reverse direction. When the parallelism error exists on the pressing surface between the pressing head 12 and the pressed product, the main body portion 1312 of the movable element 131 is properly inclined in the first through hole 114 to compensate the parallelism error existing on the pressing surface. It is understood that, in order to facilitate the generation of the proper inclination of the body portion 1312 at the first through hole 114, the diameter of the body portion 1312 is smaller than that of the first through hole 114.
It can be understood that, when the pressing assembly 10 provided in the embodiment of the present application is in a pressing state (i.e., when a product is not pressed), the position-limiting portion 1311 of the movable member 131 is lifted, and the first inclined surface 1143 and the second inclined surface 1313 are separated from each other, so that a certain gap is formed therebetween. At this time, the indenter 12 may be deflected by a certain angle in any direction until the body portion 1312 of the movable element 131 comes into contact with the inner wall of the first through hole 144, thereby achieving the angle adjustment of the indenter 12. Further, when the pressure head 12 and the pressed product are not parallel, the angle of the pressure head 12 can be automatically adjusted, and then the parallelism error of the pressing surface is compensated, so that the pressing surfaces of the pressure head 12 and the pressed product are parallel to each other, the stress of the pressed surface is uniform, and the pressing yield is improved.
Further, the main body portion 1312 is substantially matched with the second hole section 1142, the diameter of the main body portion 1312 is smaller than that of the second hole section 1142, and the main body portion 1312 is substantially in a cylindrical structure. Of course, in other embodiments, to achieve a substantial fit between the body portion 1312 and the second bore section 1142, the body portion 1312 and the second bore section 1142 may have a substantially rectangular body structure, with the body portion 1312 having a smaller cross-sectional area perpendicular to the axis of the first through-hole 114 than the second bore section 1142.
Referring to fig. 3 again, the elastic element 132 is provided with a second through hole 1321 corresponding to the first through hole 114, and the diameter of the second through hole 1321 is not smaller than the diameter of the first through hole 114. One end of the main body 1312 of the movable element 131, which is far away from the bottom wall of the groove 113, is inserted through the elastic element 132, that is, the elastic element 132 may be sleeved on one end of the main body 1312, which is far away from the bottom wall of the groove 113.
Specifically, the diameter of the second through hole 1321 is not smaller than the diameter of the first through hole 114, that is, the elastic member 132 is not pressed into the first through hole 114 when performing the pressing operation, so that both ends of the elastic member 132 always abut against the fixing structure 11 and the pressing head 12, and provide a stable elastic deformation force. It is understood that the elastic member 132 may be a spring, foam, gel, or the like that generates an elastic deformation force. In the embodiment of the present application, the elastic member 132 is made of a spring and is made into a spiral shape, and the first through hole 114 is a screw hole of the spiral spring.
Of course, in other embodiments, the first through hole 114 and the second through hole 1131 may be rectangular holes, and the cross-sectional area of the second through hole 1321 perpendicular to the axis of the first through hole 114 is not smaller than the cross-sectional area of the first through hole 114 perpendicular to the axis of the first through hole 114.
The pressing component provided by the embodiment of the application is fixedly connected with the mounting component through the fixing structure so as to fix and position the pressing component; simultaneously, connection structure wears to locate fixed knot and is connected in the pressure head for being pressed the product and carry out the pressfitting operation. Furthermore, the diameter of the moving part with the connecting structure is smaller than that of the first through hole of the fixing structure, so that the main body part of the moving part can be properly inclined during pressing operation, the parallelism error of a pressing surface is compensated, uniform stress of a pressed product is realized, and the pressing yield is improved. The pressing component that this application embodiment provided simple structure, and the compensation pressfitting face parallelism error that can be nimble compare in the fixed pressure head structure of tradition, the pressing component that this application embodiment provided can be when lamination equipment debugs, can need not very accurate regulation pressure head parallelism to reduce equipment debugging time, promote pressfitting production efficiency.

It is understood that the meaning of "a plurality" is at least two, e.g., two, three, etc., unless specifically limited otherwise. In the embodiment of the present application, two first through holes 114 are provided at the bottom of the groove 113 of the fixing structure 11 for example. Referring to fig. 8, fig. 8 is a schematic structural view of the pressing assembly 10 according to another embodiment of the present application, two first through holes 114 are formed at the bottom of the groove 113 of the fixing structure 11, two movable members 131 and two elastic members 132 of the connecting structure 11 are respectively disposed, and the two movable members 131 and the two elastic members 132 are respectively disposed in one-to-one correspondence with the two first through holes 114. Further, the two first through holes 114 may be symmetrically distributed on the bottom wall of the groove 113. It should be understood that the plurality of first through holes 114 formed in the bottom wall of the groove 113 may be symmetrically distributed on the bottom wall of the groove 113, or may be arranged and distributed on the bottom wall of the groove 113 according to a certain sequence, which is not specifically limited in this embodiment of the application. It is understood that the specific structures and connection relationships of the fixing structure 11, the pressing head 12 and the connecting structure 13 in the present embodiment are substantially the same as those described in the previous embodiments, and thus, detailed descriptions are omitted in the present embodiment.
The utility model provides a pressing component sets up a plurality of first through-holes through the recess bottom at fixed knot constructs to set up a plurality of connection structure and first through-hole one-to-one setting, when carrying out the pressfitting operation, not only can compensate pressfitting face depth of parallelism error, can also promote pressfitting stability.

Further, one side of the supporting member 133 abuts against the elastic member 132, and the other side of the supporting member 133 abuts against the pressure head 12. Specifically, the supporting member 133 is fixedly connected to the elastic member 132 and the ram 12, respectively, that is, the supporting member 133 is disposed between the elastic member 132 and the ram 12.
