Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of clamping devices, in particular to a clamping mechanism. BACKGROUND

[0002] In the process of assembling products, technicians usually perform glue sticking on some parts to realize the assembly of the parts on the products. For example, in an electronic notebook product, a technician needs to first attach double-sided tape on a rubber column, and then stick the rubber column on the product through the double-sided tape. However, in the related art, a manual single glue sticking manner is generally adopted, and the technician needs to take and stick multiple tapes in release paper one by one on corresponding parts, which is time-consuming and laborious and has low work efficiency. CONTENT OF THE UTILITY MODEL

[0003] Therefore, it is necessary to provide a clamping mechanism to improve the technical problems of low glue sticking efficiency and high labor intensity.

[0004] An embodiment of the present application provides a clamping mechanism. The clamping mechanism comprises a base, a driving assembly, and multiple clamping pieces. The base is provided with multiple mounting grooves, and each clamping piece is movably mounted in one mounting groove. In the mounting groove, the clamping piece and the base jointly form an accommodation space configured to accommodate a target object. The driving assembly is mounted on the base and connected with all the clamping pieces. The driving assembly is configured to drive all the clamping pieces to move towards the target object to clamp the target object, and to drive all the clamping pieces to move away from the target object to release the target object.

[0005] In the above clamping mechanism, multiple accommodation spaces are provided to accommodate multiple target objects at a time. Through the cooperation of the driving assembly and the multiple clamping pieces, the clamping or releasing of multiple target objects can be realized. Obviously, compared with the current manual single glue sticking, the technician can use the clamping mechanism in the present application to attach multiple tapes on corresponding target objects at a time, that is, batch glue sticking is realized, which is beneficial to improve the glue sticking efficiency, reduce the number of repeated glue sticking operations of the technician, and reduce the labor intensity of the technician.

[0006] In at least one embodiment, the driving assembly comprises a first driving piece and a pushing piece. The first driving piece and the pushing piece are both mounted on the base. One end of the pushing piece is connected with the first driving piece, and the other end of the pushing piece is connected with all the clamping pieces. The pushing piece is configured to drive all the clamping pieces to move towards or away from the target object under the action of the first driving piece.

[0007] Through the cooperation of the first driving piece and the pushing piece, a single driving piece can drive multiple clamping pieces to move, which helps to reduce the number of driving pieces used in the clamping mechanism, thereby reducing the production cost.

[0008] In at least one embodiment, the driving assembly comprises a plurality of second driving members. The plurality of second driving members are mounted on the base, and each second driving member is connected with one clamping member. The second driving member is configured to drive the corresponding clamping member to move towards or away from the target object.

[0009] By adopting the one-to-one correspondence between the second driving member and the clamping member, the flexibility of the clamping mechanism can be improved. For example, when any one or several clamping members fail, the remaining clamping members can still clamp or release the target object under the action of the corresponding second driving member, so as to ensure that the rubberizing process can continue.

[0010] In at least one embodiment, the plurality of clamping members are arranged and form a first clamping member group and a second clamping member group along the moving direction of the clamping members. The number of the pushing members is two, and the two pushing members are connected with the first driving member. One of the two pushing members is connected with all the clamping members in the first clamping member group, and the other is connected with all the clamping members in the second clamping member group.

[0011] The first driving member can simultaneously drive the two pushing members to control the clamping or releasing of the clamping members in the first clamping member group and the clamping members in the second clamping member group, which can further improve the number of target objects accommodated and clamped by the clamping mechanism without increasing the number of driving members, and further improve the rubberizing efficiency.

[0012] In at least one embodiment, the first driving member comprises a rotating member and a cam. The rotating member is rotatably inserted into the base, and the rotating member is at least partially exposed outside the base. The cam is mounted on the rotating member and located between the two pushing members. The cam is configured to rotate under the action of the rotating member and push the two pushing members to move towards or away from each other.

[0013] Through the cooperation of the rotating member and the cam, the two pushing members can move towards or away from each other, and then the clamping or releasing of the target object can be realized. The driving precision of the cam is high, and the driving effect is stable, which can improve the stability and precision of the clamping mechanism.

[0014] In at least one embodiment, the two pushing members are each provided with a first inclined surface, and the two first inclined surfaces are distributed towards each other. The two sides of the cam are each provided with a second inclined surface. When the cam rotates under the action of the rotating member, the first inclined surface cooperates with the second inclined surface.

[0015] When the cam rotates under the action of the rotating member and pushes the two pushing members to move towards or away from each other, the first inclined surface contacts the second inclined surface and slides along the second inclined surface, which can reduce the risk of jamming or blocking of the pushing member and the cam due to motion interference between the pushing member and the cam, thereby improving the smoothness of the operation of the clamping mechanism.

[0016] In at least one embodiment, the first driving member further comprises a handle for a user to hold, the handle is arranged at one end of the rotating member away from the cam and outside the base. By arranging the handle, it is convenient for a technician to operate, the technician only needs to manually rotate the handle to realize clamping or releasing the target object by the clamping mechanism, and the experience is improved.

[0017] In at least one embodiment, the clamping mechanism further comprises a limiting member, the limiting member is installed on the base, and the limiting member is configured to stop the handle to constrain the rotating range of the rotating member.

[0018] After the technician rotates the handle to the target position, the limiting member can stop the handle to constrain the rotating range of the rotating member, that is, to constrain the rotating position of the cam, so as to ensure that the cam accurately drives the pushing member to move, reduce the risk that the pushing member moves too far to damage the components due to the too large angle of the cam rotating, and improve the stability of the clamping mechanism.

[0019] In at least one embodiment, the clamping mechanism further comprises a resilient member, the resilient member is installed in the installation groove along the clamping member, one end of the resilient member abuts against the base, and the other end abuts against the clamping member.

[0020] By arranging the resilient member, the automatic reset of the clamping member can be realized. It can be understood that when the cam rotates from the highest point to the lowest point, the clamping member can move towards the target object under the elastic force of the resilient member, and the pushing member always abuts against the outer edge profile of the cam.

[0021] In at least one embodiment, the clamping mechanism further comprises a positioning member, the positioning member is installed on the base. The positioning member is configured to be inserted into a positioning hole in the release paper provided with a plurality of adhesive tapes.

[0022] By arranging the positioning member, the accuracy of the adhesive paper installation is improved, and the risk of adhesive paper deviation due to misoperation of the technician or external factors is reduced. It can be understood that when the adhesive paper is installed, the technician only needs to insert the positioning member into the positioning hole of the release paper provided with the adhesive paper to realize the positioning of the adhesive paper and the target object.

[0034] The following detailed description will further describe the present application in combination with the above-mentioned drawings. DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present application will be described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0037] The application provides a clamping mechanism. The clamping mechanism comprises a base, a driving assembly and a plurality of clamping pieces. The base is provided with a plurality of mounting grooves, and each clamping piece is movably mounted in one mounting groove. In the mounting groove, the clamping piece and the base jointly form an accommodation space configured to accommodate a target object. The driving assembly is mounted on the base and connected with all the clamping pieces. The driving assembly is configured to drive all the clamping pieces to move towards the target object to clamp the target object, and to move away from the target object to release the target object.

[0038] In the clamping mechanism, a plurality of accommodation spaces are provided, and a plurality of target objects can be accommodated at one time. Through cooperation of the driving assembly and the plurality of clamping pieces, clamping or releasing of the plurality of target objects can be realized. Obviously, compared with the current manual single adhesive tape pasting, the technical personnel can use the clamping mechanism to paste a plurality of adhesive tapes on corresponding target objects at one time, that is, batch adhesive tape pasting is realized, which is beneficial to improving the adhesive tape pasting efficiency, reducing the number of repeated adhesive tape pasting operations of the technical personnel, and reducing the labor intensity of the technical personnel.

[0039] Some embodiments of the application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0040] An embodiment of the application provides a clamping mechanism 100. The clamping mechanism 100 is used for clamping a target object 200, so as to facilitate subsequent adhesive tape pasting or assembly of the target object 200. The target object 200 can be a rubber column, a gasket or other parts that need to be pasted with adhesive tape or assembled, which is not limited in the application, and can be selected by the technical personnel according to the actual situation.

[0041] Please refer to Figures 1 to 3 The clamping mechanism 100 comprises a base 10, a driving assembly 30 and a plurality of clamping pieces 20. The base 10 is provided with a plurality of mounting grooves 11, and each clamping piece 20 is movably mounted in one mounting groove 11. In each mounting groove 11, the clamping piece 20 and the base 10 jointly form an accommodation space 12 configured to accommodate the target object 200. Through the plurality of accommodation spaces 12, the clamping mechanism 100 can accommodate a plurality of target objects 200 at one time.

[0042] In some embodiments, the driving assembly 30 is mounted on the base 10 and connected with all the clamping pieces 20. The driving assembly 30 is configured to drive all the clamping pieces 20 to move towards the target object 200 to clamp the target object 200, and to move away from the target object 200 to release the target object 200. Through cooperation of the driving assembly 30 and the plurality of clamping pieces 20, clamping or releasing of the plurality of target objects 200 can be realized.

[0043] Please refer toFigures 4 to 7 For example, when the adhesive paper 310 in the release paper 300 needs to be attached to the target objects 200, the technician places the target objects 200 in the corresponding accommodation spaces 12. The driving assembly 30 drives all the clamping members 20 to move towards the target objects 200, and each clamping member 20 clamps the corresponding target object 200 together with the slot wall of the corresponding mounting slot 11, that is, the fixation of the target objects 200 is achieved.

[0044] After the target objects 200 are fixed, the technician assembles the release paper 300 on the clamping mechanism 100 (specifically, one adhesive paper 310 corresponds to one target object 200), and then attaches the adhesive paper 310 to the corresponding target object 200. After the adhesive paper 310 is attached, the driving assembly 30 drives all the clamping members 20 to move away from the target objects 200, and each clamping member 20 releases the corresponding target object 200, that is, the fixation of the target objects 200 is released.

[0045] Compared with the current manual single adhesive attachment, the technician can use the clamping mechanism 100 in the present application to attach multiple adhesive papers 310 to the corresponding target objects 200 at one time, which realizes batch adhesive attachment, improves the adhesive attachment efficiency, reduces the number of repeated adhesive attachment operations of the technician, and reduces the labor intensity of the technician.

[0046] Please refer to Figure 3 , Figure 8 and Figure 9 In some embodiments, the driving assembly 30 includes a first driving member 31 and a pushing member 32. The first driving member 31 and the pushing member 32 are both installed on the base 10. One end of the pushing member 32 is connected to the first driving member 31, and the other end of the pushing member 32 is connected to all the clamping members 20. The pushing member 32 is configured to drive all the clamping members 20 to move towards or away from the target objects 200 under the action of the first driving member 31.

[0047] Understandably, when the target objects 200 need to be clamped, the first driving member 31 drives the pushing member 32 to move, and the pushing member 32 drives all the clamping members 20 to move towards the target objects 200 to clamp the target objects 200. When the target objects 200 need to be released, the first driving member 31 drives the pushing member 32 to move in the opposite direction, and the pushing member 32 drives all the clamping members 20 to move away from the target objects 200, thereby releasing the target objects 200.

[0048] Through the cooperation of the first driving member 31 and the pushing member 32, a single driving member can drive multiple clamping members 20 to move, which helps to reduce the number of driving members used in the clamping mechanism 100, thereby reducing the production cost.

[0049] In some embodiments, the driving assembly 30 comprises a plurality of second driving members (not shown in the figure). The plurality of second driving members are each mounted on the base 10, and each of the second driving members is connected with one of the clamping members 20. The second driving members are configured to drive the corresponding clamping members 20 to move towards or away from the target object 200.

[0050] It can be understood that, when it is required to clamp the target object 200, each of the second driving members directly drives the corresponding clamping member 20 to move towards the target object 200 to clamp the target object 200. When it is required to release the target object 200, the second driving member directly drives the corresponding clamping member 20 to move away from the target object 200 to release the target object 200.

[0051] By adopting the one-to-one correspondence between the second driving members and the clamping members 20, the flexibility of the clamping mechanism 100 can be improved. For example, when one or more of the clamping members 20 fail, the remaining clamping members 20 can still clamp or release the target object 200 under the action of the corresponding second driving members, so as to ensure that the gluing process can continue.

[0052] For example, the second driving members are telescopic cylinders, and each of the telescopic cylinders is connected with one of the clamping members 20. When the telescopic cylinder extends, the telescopic cylinder drives the clamping member 20 to move towards the target object 200 to clamp the target object 200. When the telescopic cylinder retracts, the telescopic cylinder drives the clamping member 20 to move away from the target object 200 to release the target object 200.

[0053] In other embodiments, the second driving members can also be other driving members, which are not limited in the present application, and can be selected by those skilled in the art according to actual conditions.

[0054] Please refer to Figure 1 , Figure 8 and Figure 9 In some embodiments, the plurality of clamping members 20 are arranged and form a first clamping member group (not shown in the figure) and a second clamping member group (not shown in the figure) along the moving direction of the clamping members 20. That is, the plurality of mounting grooves 11 are arranged and form a first mounting groove group (not shown in the figure) and a second mounting groove group (not shown in the figure) along the moving direction of the clamping members 20.

[0055] In some embodiments, the arrangement mode of the plurality of clamping members 20 needs to be set according to the arrangement mode of the plurality of adhesive papers 310 in the release paper 300. That is, the arrangement mode of the plurality of accommodating spaces 12 needs to be set according to the arrangement mode of the plurality of adhesive papers 310 in the release paper 300.

[0056] In this way, it is beneficial to ensure that the target object 200 is positioned relative to the adhesive paper 310, and to reduce the risk of the target object 200 being misaligned with the adhesive paper 310 or not being attached with the adhesive paper 310.

[0057] For example, the adhesive paper 310 in the release paper 300 is arranged in a matrix, and the plurality of clamping members 20 are also arranged in a matrix. In other embodiments, the adhesive paper 310 in the release paper 300 can also be arranged in a circular shape, and the plurality of clamping members 20 are also arranged in a circular shape. The present application does not limit this, and those skilled in the art can select according to actual conditions. Figure 4 Figure 7 For example, the adhesive paper 310 in the release paper 300 is arranged in a matrix, and the plurality of clamping members 20 are also arranged in a matrix. In other embodiments, the adhesive paper 310 in the release paper 300 can also be arranged in a circular shape, and the plurality of clamping members 20 are also arranged in a circular shape. The present application does not limit this, and those skilled in the art can select according to actual conditions.

[0058] In some embodiments, the number of pushers 32 is two, and both of the two pushers 32 are connected with the first driving member 31. One of the two pushers 32 is connected with all the clamping members 20 in the first group of clamping members 20, and the other is connected with all the clamping members 20 in the second group of clamping members 20.

[0059] For example, the two pushers 32 are defined as a first pusher (not shown in the figure) and a second pusher (not shown in the figure). The first pusher is connected with all the clamping members 20 in the first group of clamping members 20, and the second pusher is connected with all the clamping members 20 in the second group of clamping members 20.

[0060] When it is necessary to clamp the target object 200, the first driving member 31 simultaneously drives the first pusher and the second pusher to move towards each other, the first pusher drives all the clamping members 20 in the first group of clamping members 20 to move towards the target object 200 to clamp the target object 200. At the same time, the second pusher drives all the clamping members 20 in the second group of clamping members 20 to move towards the target object 200 to clamp the target object 200.

[0061] When it is necessary to release the target object 200, the first driving member 31 simultaneously drives the first pusher and the second pusher to move away from each other, the first pusher drives all the clamping members 20 in the first group of clamping members 20 to move away from the target object 200 to release the target object 200. At the same time, the second pusher drives all the clamping members 20 in the second group of clamping members 20 to move away from the target object 200 to release the target object 200.

[0062] The first driving member 31 can simultaneously drive the two pushers 32 to control the clamping or release of the clamping members 20 in the first group of clamping members 20 and the clamping members 20 in the second group of clamping members 20, which is beneficial to further increase the number of target objects 200 accommodated and clamped by the clamping mechanism 100 without increasing the number of driving members, and further improve the efficiency of gluing.

[0063] For example, the adhesive paper 310 in the release paper 300 is arranged in a matrix, and the plurality of clamping members 20 are also arranged in a matrix. In other embodiments, the adhesive paper 310 in the release paper 300 can also be arranged in a circular shape, and the plurality of clamping members 20 are also arranged in a circular shape. The present application does not limit this, and those skilled in the art can select according to actual conditions. Figure 3 Figure 8 ​​And Figure 9 In some embodiments, the first driving member 31 comprises a rotating member 311 and a cam 312. The rotating member 311 is rotatably connected to the base 10, and the rotating member 311 is at least partially exposed to the base 10. The cam 312 is mounted on the rotating member 311 and located between the two pushing members 32. The cam 312 is configured to rotate under the action of the rotating member 311 and push the two pushing members 32 to move towards or away from each other.

[0064] Through the cooperation of the rotating member 311 and the cam 312, the two pushing members 32 can be moved towards or away from each other, thereby achieving clamping or releasing of the target object 200. The driving precision of the cam 312 is high, and the driving effect is stable, which is beneficial to improve the stability and precision of the clamping mechanism 100.

[0065] It is worth noting that the cam 312 is configured to rotate to a first position and a second position under the action of the rotating member 311. When the cam 312 is in the first position, the cam 312 pushes the two pushing members 32 to move away from each other, and the clamping member is in a released state. When the cam 312 is in the second position, the cam 312 drives the two pushing members 32 to move towards each other, and the clamping member is in a clamped state.

[0066] In other embodiments, the cam 312 can adopt a lifting form to push the two pushing members 32 to move towards or away from each other. For example, the cam 312 is connected with a lifting cylinder. When the lifting cylinder drives the cam 312 to rise, the cam 312 pushes the two pushing members 32 to move away from each other. When the lifting cylinder drives the cam 312 to descend, the cam 312 drives the two pushing members 32 to move towards each other. The present application does not limit this, and those skilled in the art can select according to actual conditions.

[0067] It is also necessary to note that in other embodiments, a plurality of clamping member groups can be added to further increase the number of clamped target objects 200. Correspondingly, the number of cams 312 needs to be increased, and one cam 312 is arranged between every two clamping member groups. The present application does not limit this, and those skilled in the art can select according to actual conditions.

[0068] Please refer to Figure 8 And Figure 9 In some embodiments, the two pushing members 32 are each provided with a first inclined surface 3121, and the two first inclined surfaces 3121 are distributed towards each other. The cam 312 is provided with a second inclined surface 321 on each side. When the cam 312 rotates under the action of the rotating member 311, the first inclined surface 3121 cooperates with the second inclined surface 321.

[0069] Understandably, when the cam 312 rotates under the action of the rotating member 311 and pushes the two pushers 32 to move towards or away from each other, the first inclined surface 3121 contacts and slides along the second inclined surface 321.

[0070] By arranging the first inclined surface 3121 and the second inclined surface 321, the risk of the pushers 32 and the cam 312 being stuck or jammed due to movement interference between them is reduced, thereby improving the smoothness of the operation of the clamping mechanism 100.

[0071] Please refer to Figure 1 , Figure 8 and Figure 9 In some embodiments, the first driving member 31 further comprises a handle 33 for a user to hold, the handle 33 being arranged at one end of the rotating member 311 away from the cam 312 and located outside the base 10. By arranging the handle 33, the convenience of operation for a technician is improved, and the technician only needs to manually rotate the handle 33 to achieve clamping or releasing of the target object 200 by the clamping mechanism 100, thereby improving the experience of use.

[0072] For example, when it is necessary to clamp the target object 200, the technician manually rotates the handle 33 counterclockwise, the handle 33 drives the rotating member 311 to rotate counterclockwise, and the cam 312 rotates from the first position to the second position. The cam 312 drives the two pushers 32 to move towards each other, and the pushers 32 drive the clamping members 20 to move towards the target object 200 to clamp the target object 200.

[0073] When it is necessary to release the target object 200, the technician manually rotates the handle 33 clockwise, the handle 33 drives the rotating member 311 to rotate clockwise, and the cam 312 rotates from the second position to the first position. The cam 312 drives the two pushers 32 to move away from each other, and the pushers 32 drive the clamping members 20 to move away from the target object 200 to clamp the target object 200.

[0074] Please refer to Figure 1 , Figure 5 and Figure 6 In some embodiments, the clamping mechanism 100 further comprises a limiting member 40, the limiting member 40 being installed on the base 10 and configured to stop the handle 33 to constrain the rotation range of the rotating member 311.

[0075] It should be noted that after the technician rotates the handle 33 to the target position (specifically the first position and / or the second position), the limiting piece 40 can stop the handle 33, so as to constrain the rotation range of the rotating piece 311, that is, constrain the rotation position of the cam 312, which is beneficial to ensure that the cam 312 accurately drives the pusher 32 to move, reduce the risk of damaging the components due to the excessive rotation angle of the cam 312, and improve the stability of the clamping mechanism 100.

[0076] For reference Figure 8 and Figure 9 In some embodiments, the clamping mechanism 100 further comprises an elastic piece 50, which is movably installed in the installation slot 11 along the clamping piece, one end of the elastic piece 50 abuts against the base 10, and the other end abuts against the clamping piece 20. Through the arrangement of the elastic piece 50, the automatic reset of the clamping piece 20 can be realized.

[0077] It should be noted that when the cam 312 rotates from the highest point (specifically the first position) to the lowest point (specifically the second position), the clamping piece 20 can move in the direction of approaching the target object 200 under the elastic force of the elastic piece 50, and the pusher 32 always abuts against the outer edge profile of the cam 312.

[0078] For reference Figure 4 and Figure 7 In some embodiments, the clamping mechanism 100 further comprises a positioning piece 60, which is installed on the base 10. The positioning piece 60 is configured to be inserted into the positioning hole 320 in the release paper 300 provided with a plurality of adhesive papers. It can be understood that when the adhesive paper 310 is installed, the technician only needs to insert the positioning piece 60 into the positioning hole 320 in the release paper 300 provided with the adhesive paper 310, so as to realize the positioning of the adhesive paper 310 and the target object 200.

[0079] Through the arrangement of the positioning piece 60, it is beneficial to improve the installation accuracy of the adhesive paper 310 and reduce the risk of offset of the adhesive paper 310 due to the misoperation of the technician or external factors.

[0080] In addition, those skilled in the art should understand that the above embodiments are only used to illustrate the present application, and are not used as a limitation to the present application, and any appropriate changes and modifications to the above embodiments within the spirit and principles of the present application are within the scope of the present application.
