Description

Technical Field

[0001] The present application relates to the technical field of mechanical parts assembly, and in particular to a bonding and pressing device. Background Art

[0002] Magnets are widely used in traditional industry, medicine, astronomy, military industry and other industries. Magnets can generate magnetic fields and have the characteristics of attracting ferromagnetic materials such as iron, nickel, cobalt and other metals. It is precisely because of this characteristic that the magnetic field of the magnet can be strengthened by bonding the magnet with the ferromagnetic material to form a magnetic coupling component. For example, in the production process of medical centrifugal pumps, the above-mentioned magnetic coupling components need to be assembled to drive the centrifugal pump to work.

[0003] However, in the process of assembling and producing magnetic coupling components in the prior art, ferromagnetic parts are often manually bonded to N-pole or S-pole magnets by traditional manual assembly. At the same time, in order for the bonding glue to achieve the best fixing effect, it is necessary to shorten the gap between the two until the glue is initially solidified. However, by manually bonding the magnets, it is difficult to ensure the flatness of the magnets after bonding and the consistency of the overall size of the magnetic coupling assembly. And when the magnets are manually pressed hard to solidify the glue, the pressure and time are uncontrollable. And from the perspective of cost consumption, manually assembling magnets to ferromagnetic parts not only places high demands on the operators, but also greatly reduces work efficiency, ultimately increasing the company's employment costs and reducing the company's production efficiency.

[0037] As described in the background technology, magnets can generate magnetic fields and have the characteristics of attracting ferromagnetic materials such as iron, nickel, cobalt and other metals. It is precisely because of this characteristic that the magnetic field of the magnet can be strengthened by fitting the magnet with the ferromagnetic material to form a magnetic coupling assembly. However, in the process of assembling and producing magnetic coupling assemblies in the prior art, ferromagnetic parts are often manually bonded to N-pole or S-pole magnets by traditional manual assembly. At the same time, in order to allow the bonding glue to achieve the best fixing effect, it is necessary to shorten the gap between the two with force until the glue is initially solidified. However, by manually operating the bonding magnet, it is difficult to ensure the flatness of the magnet after bonding and the consistency of the overall size of the magnetic coupling assembly. And when the magnet is manually pressed to solidify the glue, the pressure and time are uncontrollable. And from the perspective of cost consumption, manually assembling the magnet to the ferromagnetic parts not only requires high requirements for the operator, but also greatly reduces the work efficiency, ultimately increasing the employment cost of the enterprise and reducing the production efficiency of the enterprise.

[0038] To this end, the present application provides a bonding and clamping device, which uses electric or pneumatic control to move the first part to bond the first part to the second part, thereby enabling semi-automatic or even fully automatic assembly to form a product and ensuring the overall size of the product.

[0039] The structure of the bonding and pressing device in the present application is described below by taking the first part as a magnet, the second part as a ferromagnetic part, and the product formed by assembling the two as a magnetic coupling assembly as an example. It can be understood that in other embodiments, the bonding and pressing device of the present application is not limited to being used to bond and fix a magnet to a ferromagnetic part to form a magnetic coupling assembly, and can also be used to bond any part to another part to form a desired product, which is not limited here.

[0040] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 The structure diagram of the bonding and pressing device 10 in one embodiment of the present application is shown. The bonding and pressing device 10 provided in one embodiment of the present application includes a control box 100, a base 200, a parts placement table 300, a bonding assembly 400 and a pressing assembly 500. The base 200 is arranged on the control box 100. Figure 1 and Figure 2 In the embodiment shown in , the base 200 is arranged on the upper surface of the control box 100, the part placement table 300 and the bonding assembly 400 are arranged on the base 200, the pressing assembly 500 is arranged on the control box 100, and the bonding assembly 400 and the pressing assembly 500 are arranged beside the part placement table 300. The part placement table 300 is used to carry the ferromagnetic part 30 (i.e., the second part); the bonding assembly 400 is used to carry the magnet (i.e., the first part, Figure 1 and Figure 2 The adhesive component 400 is used to bond and fix the ferromagnetic part 30 to the side wall of the ferromagnetic part 30; the clamping component 500 is used to clamp and fix the ferromagnetic part 30 on the part placement table 300 to prevent the ferromagnetic part from shifting at will during the process of the adhesive component 400 bonding the magnet to the ferromagnetic part 30; the control box 100 is used for the operator to control the opening and closing of the adhesive clamping device 10 and control the actions of the adhesive component 400 and the clamping component 500.

[0041] Specifically, in one embodiment, the control box 100 is a hollow structure, in which electronic components and control components are arranged, and a main switch 101 and a plurality of control switches are arranged on the outer wall thereof, wherein the plurality of control switches include a first switch 102, a second switch 103 and an emergency stop switch 104, wherein the first switch 102 and the second switch 103 are electrically connected to the bonding assembly 400 and the pressing assembly 500 through the electronic components and the control components respectively, the first switch 102 is used to control the action of the bonding assembly 400, the second switch 103 is used to control the action of the pressing assembly 500, and the emergency stop switch 104 is used to stop the action of the bonding assembly 400 and the pressing assembly 500 in an emergency. In addition, a power source switch 105 is also arranged on the control box 100, which is used to connect an external power source (such as an air source) to the bonding and pressing device 10, so as to provide power for the bonding assembly 400 and the pressing assembly 500.

[0042] It is understandable that in other embodiments, the base 200 may not be set on the control box 100, but may be set separately from the control box 100, and the two may be interconnected by a cable. Alternatively, the control box 100 may not be set, and the electrical components and control components may be set in the base 200. The actions of components such as the bonding assembly 400 and the clamping assembly 500 may be controlled by remote control, without specific limitation.

[0043] See also Figure 3 and Figure 4 ,exist Figure 3 and Figure 4In the embodiment shown in , the part placement table 300 is arranged in the middle of the base 200, and there are two bonding components 400. The two bonding components 400 are respectively arranged on opposite sides of the part placement table 300 along the radial direction of the part placement table 300, so that the two bonding components 400 can simultaneously bond and fix the two magnets 20 to the outer peripheral side wall of the ferromagnetic part 30. At the same time, the two relatively arranged bonding components 400 can jointly clamp the ferromagnetic part 30 when bonding the magnet 20 to the ferromagnetic part 30, thereby preventing the ferromagnetic part 30 from moving at will on the part placement table 300, and avoiding the situation where the magnet 20 cannot be bonded to the correct position on the side wall of the ferromagnetic part 30.

[0044] In other embodiments, the number of adhesive assemblies 400 is not limited to two, but may be an even number, and the multiple adhesive assemblies 400 are arranged in pairs, and the two adhesive assemblies 400 in each pair of adhesive assemblies 400 are arranged opposite to each other along the radial direction of the component placement table 300. In this way, the multiple adhesive assemblies 400 act simultaneously, and the multiple magnets 20 can be bonded to the side wall of the ferromagnetic component 30 at the same time, so that the side wall of the ferromagnetic component 30 in the circumferential direction thereof is bonded to multiple magnets 20 at one time.

[0045] In a specific implementation, please continue to refer to Figure 3 and Figure 4 Each bonding assembly 400 includes a first driving member 410 and a bonding arm 420. The first driving member 410 is fixedly mounted on the base 200. The first driving member 410 may be a cylinder or an electric cylinder, etc. The bonding arm 420 is movably connected to the first driving member 410 in cooperation with each other. The bonding arm 420 is used to carry the magnet 20 and bond the magnet 20 to the ferromagnetic part 30. Driven by the first driving member 410, the bonding arm 420 can move relative to the first driving member 410, so that it can approach or move away from the part placement table 300 along the radial direction of the part placement table 300, so that multiple magnets 20 can be bonded and fixed to the outer peripheral surface of the ferromagnetic part 30 repeatedly and in sequence.

[0046] It is understandable that the end of the bonding arm 420 can be made of iron material, which can be directly adsorbed with the magnet 20, so as to carry the magnet 20 for transfer and make the magnet 20 against the side wall of the ferromagnetic part 30, so as to bond the glued magnet 20 to the side wall of the ferromagnetic part 30. After waiting for the glue on the magnet 20 to solidify, the adhesive force of the glue is greater than the magnetic adsorption force between the bonding arm 420 and the magnet 20. When the bonding arm 420 moves away from the part placement table 300, it can be separated from the magnet 20 bonded to the ferromagnetic part 30 and adsorb a new magnet 20, so as to prepare to bond the new magnet 20 to the side wall of the ferromagnetic part 30 to which the magnet 20 is not bonded.

[0047] It can also be understood that the end of the bonding arm 420 can also be a structure such as a nozzle or a clamping claw that can carry and transfer the magnet 20, and the specific details are not limited.

[0048] Preferably, as a further improvement, each bonding assembly 400 further includes a linear guide 430, which is movably connected to the first driving member 410, and the bonding arm 420 is detachably connected to the linear guide 430, and can be installed at different positions of the linear guide 430 in the radial direction of the part placement table 300 by fasteners such as screws. Driven by the first driving member 410, the linear guide 430 and the bonding arm 420 can move closer to or away from the part placement table 300 along the radial direction of the part placement table 300.

[0049] In this way, by enabling the bonding arm 420 to be detachably mounted on the linear guide rail 430 at different positions in the radial direction of the part placement table 300, it is only necessary to select a first driving member 410 with a smaller stroke to bond the magnet 20 to ferromagnetic parts 30 with different outer diameters, thereby avoiding the situation where the bonding arm 420 is unable to bond the magnet 20 to the ferromagnetic part 30 with a smaller outer diameter due to insufficient stroke of the first driving member 410. There is also no need to select a first driving member 410 with a larger stroke in order to enable the bonding arm 420 to bond the magnet 20 to the ferromagnetic part 30 with a smaller outer diameter, thereby saving the production cost of the device.

[0050] It should be noted that the bonding and pressing device 10 provided in the present application may not be provided with a base 200. In this case, the part placement table 300 and the bonding assembly 400 may be directly provided on the control box 100 or placed on an external work platform.

[0051] More preferably, when the first driving member 410 is a cylinder, the first driving member 410 is further provided with a first vent 411 for allowing compressed air to pass into the first driving member 410, so that after the bonding arm 420 bonds the magnet 20 to the ferromagnetic part 30, under the control of the electrical components and control components in the control box 100, the bonding arm 420 can be pressed against the magnet 20 with a constant air pressure within a certain time range, and then the magnet 20 can be pressed against the side wall of the ferromagnetic part 30 with a constant force, so that the holding force and holding time of the bonding arm 420 can be controlled, and two important parameters, the bonding pressure and curing parameters of the magnet 20 bonded to the ferromagnetic part 30, can also be controlled, thereby ensuring good bonding quality.

[0052] For further information, please refer to Figure 3 and Figure 4In this embodiment, the number of the clamping assemblies 500 is two, and the two clamping assemblies 500 are relatively arranged on the axial side or circumferential side of the part placement platform 300 along the other radial direction of the part placement platform 300. In the embodiment shown in the figure, the two clamping assemblies 500 are arranged on the circumferential side of the part placement platform. Specifically, it can be installed on the control box 100 or on the base 200. In this embodiment, the two clamping assemblies 500 are installed on the control box 100, and each clamping assembly 500 has a pressure head 520 that can be controlled to move relative to the part placement platform 300, so as to clamp or loosen the ferromagnetic part 30 placed on the part placement platform 300, so as to further ensure that the ferromagnetic part 30 will not move arbitrarily when the bonding assembly 400 bonds the magnet 20, so as to ensure that the magnet 20 is accurately bonded to the predetermined position on the ferromagnetic part 30. It can be understood that there is no limit to the number of the clamping assemblies 500, and there can be only one or more, which can be set arbitrarily according to needs.

[0053] Specifically, the clamping assembly 500 includes a second driving member 510 and a connecting rod 530. The connecting rod 530 is a bent rod-shaped structure. The pressing head 520 is connected to one end of the connecting rod 530. The other end of the connecting rod 530 can be movably connected to the second driving member 510. The second driving member 510 can also be a cylinder or an electric cylinder. The connecting rod 530 and the pressing head 520 can be driven by the second driving member 510 to rise and fall together along the height direction shown in the figure (i.e., the height direction of the clamping assembly) relative to the second driving member 510 to clamp or loosen ferromagnetic parts 30 of different thicknesses, and can rotate relative to the second driving member 510 around an axis extending along the height direction, so as to facilitate operation when removing the ferromagnetic part 30 from the part placement table 300. Preferably, the second driving member 510 is provided with a second vent 511 through which compressed air can be introduced into the second driving member 510 so that the pressing head 520 can press the ferromagnetic part 30 placed on the part placement table 300 with a constant pressure.

[0054] In other embodiments, the second driving member 510 may only drive the connecting rod 530 and the pressing head 520 to rise and fall, or only drive the connecting rod 530 and the pressing head 520 to rotate, but in this case, the pressing head 520 can only press the ferromagnetic part 30 of a certain thickness. Of course, the pressing assembly 500 may not be provided, and a locking feature may be provided on the part placement table 300 so that the ferromagnetic part 30 is fixed on the part placement table 300 when it is placed on the part placement table 300.

[0055] Please continue reading Figure 3 and Figure 4In a preferred embodiment, the part placement table 300 is a disc-shaped structure, or a square disc-shaped structure, etc. When it is necessary to bond multiple magnets 20 to the outer wall of the ferromagnetic part 30, in order to facilitate the rotation of the ferromagnetic part 30, the part placement table 300 is rotatably mounted on the base 200 around its own central axis, so that the part placement table 300 can rotate relative to the base 200 around its own central axis. In this way, after the two bonding components 400 arranged opposite to each other have bonded the two bonding components 400, the part placement table 300 is rotated to rotate the ferromagnetic part 30 by an angle, and the bonding component 400 can sequentially bond multiple magnets 20 to the side wall of the ferromagnetic part 30 that is not bonded with the magnets 20. The way to rotate the part placement table 300 can be manually rotated by an operator, or a control button can be set on the console, and the operator operates the control button to make the electronic component and the control component control the part placement table 300 to rotate automatically, and there is no special limitation here.

[0056] As a further improvement, the upper surface of the part placement table 300 is provided with a plurality of grooves 301 evenly arranged along the circumferential direction of the part placement table 300; when the bonding arm 420 carries the magnet 20 and is pressed against the ferromagnetic part 30 to bond the magnet 20 to the ferromagnetic part 30, the bonding arm 420 is partially limited in the corresponding groove 301, so that the groove 301 can guide the bonding arm 420, and can guide the bonding arm 420 to bond the magnet 20 to the corresponding correct position on the ferromagnetic part 30, and the bonding position is uniform and controllable.

[0057] More preferably, in order to enable the parts placement platform 300 to rotate relative to the base 200 and to be limited at a certain position when rotating to the position without rotating arbitrarily, refer to Figure 5 The bonding and pressing device 10 further includes a limiting assembly 600, which is partially embedded in the base 200. Specifically, a mounting hole 201 can be opened on the base 200, and the limiting assembly 600 is partially embedded in the mounting hole 201. The limiting assembly 600 is used to engage with the part placement table 300, so that the part placement table 300 can be limited to a predetermined position on the base 200 on the part placement table 300, so as to ensure the circumferential bonding accuracy of the bonding assembly 400 bonding the magnet to the ferromagnetic part.

[0058] exist Figure 5In the embodiment shown in , there are four limit assemblies 600, and the four limit assemblies 600 are evenly spaced along the circumferential direction of the part placement platform 300, so that when the part placement platform 300 rotates relative to the base 200 around its own central axis, the part placement platform 300 can be limited at four different angular positions. There is no limit to the number of limit assemblies 600, and there can be more. When there are more limit assemblies 600, the part placement platform 300 can be limited at more positions in its own circumferential direction, and can be arbitrarily set according to needs.

[0059] Specifically, in one embodiment, the limit assembly 600 is a structure of an elastic universal ball, which includes a housing 610, a limit block 620 and an elastic element ( Figure 6 ), wherein the shell 610 is embedded in the mounting hole 201 provided in the base 200, the limit block 620 is preferably a ball, a part of which is embedded in the shell 610 and the other part is exposed from the shell 610, or the limit block 620 is completely exposed from the shell 610, the elastic element is provided in the shell 610, and is connected to the limit block 620 and the shell 610 at the same time, so that the limit block 620 is connected to the base 200 through the elastic element; correspondingly, a limit groove ( Figure 6 not shown).

[0060] In this way, when the part placement table 300 and the limit assembly 600 are engaged with each other, the part of the limit block 620 exposed outside the shell 610 is limited in the limit groove, or when the limit block 620 is completely exposed outside the shell 610, the limit block 620 is completely limited in the limit groove, so that the part placement table 300 cannot rotate around its own central axis relative to the base 200 when no external force is applied; and when the part placement table 300 rotates relative to the base 200 under the action of external force, the limit block 620 is supported by the bottom wall of the part placement table 300 and retracted into the base 200, and at the same time, the elastic element is compressed by the limit block 620 and generates an elastic force for resetting the limit block 620 and limiting it in the limit groove.

[0061] In another embodiment, the limit assembly 600 may also only include a limit block 620 and an elastic element. The elastic element is arranged in the mounting hole 201 opened in the base 200 and is simultaneously connected to the base 200 and the limit block 620. The limit block 620 is partially exposed from the mounting hole 201 and can also play the same limiting role on the part placement table 300 when the part placement table 300 is not subjected to external force. It will not be repeated here.

[0062] In addition, in order to make the part placement table 300 rotate more smoothly relative to the base 200, a bearing 700 is also provided on the outer peripheral surface of the part placement table 300 to reduce the friction coefficient of the part placement table 300 during rotation, making the rotation smoother and ensuring its rotation accuracy.

[0063] Further, see Figure 6 In order to facilitate the removal of the magnetic coupling assembly 40 from the part placement table 300 after the magnet 20 and the ferromagnetic part 30 are assembled to form the magnetic coupling assembly 40, the bonding and pressing device 10 further includes a lifting assembly 800, which is connected to the bottom wall of the part placement table 300 and is used to lift the part placement table 300 in the height direction to detach the part placement table 300. Correspondingly, refer to Figure 1 and Figure 2 A third switch 106 may also be provided on the outer wall of the control box 100 . The third switch 106 is electrically connected to the lifting assembly 800 through the electronic components and control components inside the control box 100 , so that the operator can control the action of the lifting assembly 800 by operating the third switch 106 .

[0064] Specifically, combined Figure 1 and Figure 6 As shown, the lifting assembly 800 includes a third driving member 810 and a lifting rod 820. There are multiple lifting rods 820, each of which is penetrated by the base 200, and one end of each lifting rod 820 is connected to the third driving member 810, and the other end is connected to the part placement table 300. In the non-lifted state, most of the lifting rod 820 and the third driving member 810 are accommodated in the control box 100. The third driving member 810 can also be a cylinder or an electric cylinder, which is used to drive the lifting rod 820 to rise together with the part placement table 300 in the height direction to lift the part placement table 300 upward, or after the lifting rod 820 and the part placement table 300 rise to a preset height together, the lifting rod 820 and the part placement table 300 are driven to descend together to the initial position.

[0065] In order to perform power control more efficiently, in some embodiments, the first driving member 410, the second driving member 510 and the third driving member 810 are pneumatically controlled.

[0066] The following combination Figures 1 to 6 , introduce the operating steps of the bonding and pressing device 10 provided by the present application:

[0067] The first step, such as Figures 1 to 4As shown, the ferromagnetic part 30 is placed on the part placement table 300, the magnet 20 after glue application is placed on the bonding arm 420 of the bonding component 400, and the second switch 103 is pressed. The compressed air enters the second driving component 510 from the second air vent 511 of the second driving component 510. The clamping component 500 uses the air pressure of the compressed air to achieve the rotation and clamping action, so that the pressure head 520 presses the ferromagnetic part 30 to fix the ferromagnetic part 30.

[0068] In the second step, the first switch 102 is pressed, and compressed air enters the first driving member 410 from the first vent 411 of the first driving member 410, so that the linear guide 430 of the bonding assembly 400 and the bonding arm 420 are linked together and approach the part placement table 300, until the magnet 20 on the bonding arm 420 contacts the ferromagnetic part 30 and is held against the ferromagnetic part 30 for a period of pressure holding time. After the pressure holding time is maintained, the first driving member 410 and the second driving member 510 are depressurized, and the bonding arm 420 and the pressure head 520 are both released and return to the initial position.

[0069] The third step is to rotate the part placement table 300 so that the side wall of the ferromagnetic part 30 that is not bonded with the magnet 20 faces the bonding arm 420, repeat the above steps so that new magnets 20 are bonded to other positions of the ferromagnetic part 30, rotate the part placement table 300 again, and repeat the above steps until the side walls of the ferromagnetic part 30 are fully bonded with the magnets 20, and finally complete the assembly of the magnetic coupling component 40.

[0070] Step 4: After assembly, Figure 1 and Figure 6 As shown, the third switch 106 is pressed again, so that the lifting assembly 800 lifts up the part placement table 300 carrying the magnetic coupling assembly 40, and removes the magnetic coupling assembly 40 from the part placement table 300.

[0071] It can be seen that the above-mentioned bonding and clamping device only needs to manually place the ferromagnetic parts on the parts placement table, and then the magnet can be bonded to the ferromagnetic parts by machine instead of manual labor to form a magnetic coupling assembly, thereby ensuring the flatness of the magnet after bonding and the consistency of the overall size of the magnetic coupling assembly, and can also control the clamping time of the magnet and the ferromagnetic parts, thereby ensuring the consistency of the glue curing effect during the assembly process. Compared with the traditional manual assembly method, it can greatly improve the production efficiency of batch assembly of products, thereby reducing the company's employment costs. In addition, the above-mentioned bonding and clamping device has a delicate and simple structure, is easy to produce and carry, and has strong practicality and broad application prospects.

[0072] Finally, it should be noted that the various technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
