Abstract
Description
Technical Field
[0001] This application relates to the technical field of drawing force testing devices, and particularly relates to a testing mechanism. Background Art
[0002] Sometimes, connection components such as snap fasteners need to be bonded on electronic products. After bonding, a drawing test needs to be performed on the connection components to determine whether the bonding strength of the connection components relative to the electronic products meets the standard. The connection components usually have a small gap. Currently, during testing, generally, the testing mechanism is inserted into the gap of the connection components, and then a preset pulling force is applied for testing. However, due to the small gap of the connection components, the size of the part of the testing mechanism inserted into the gap of the connection components is also small, and this part is prone to break during the drawing test, resulting in a short service life of the testing mechanism. Summary of the Utility Model
[0003] In view of the above, it is necessary to propose a testing mechanism that can improve the service life of the testing mechanism.
[0004] An embodiment of this application provides a testing mechanism for testing whether the bonding strength between a connection component bonded to a workpiece and the workpiece meets the standard. The testing mechanism includes a drawing component and a driving component. The drawing component is provided with a through hole for inserting the connection component. The driving component is connected to the drawing component. The driving component is used to apply a preset pulling force along a first direction and draw the connection component through the drawing component, so as to judge whether the bonding strength between the connection component and the workpiece meets the standard according to the separation situation between the connection component and the workpiece.
[0005] In some embodiments, the connection component includes a small part bonded to the workpiece and a clamping part connected to the small part. The clamping part has two oppositely arranged clamping portions. The drawing component has a separating portion. The separating portion is located in the through hole and divides the through hole into a first sub-hole and a second sub-hole that are spaced along a second direction. The first sub-hole is used for inserting one of the clamping portions, and the second sub-hole is used for inserting the other clamping portion. The second direction is perpendicular to the first direction.
[0006] In some embodiments, the clamping part is movably connected to the small part. The drawing component further includes a first magnetic component. The first magnetic component is arranged on the inner wall of the first sub-hole far from the second sub-hole or the first magnetic component is arranged on the inner wall of the second sub-hole far from the first sub-hole. The first magnetic component is used to apply a suction force towards the first magnetic component to the two clamping portions.
[0007] In some embodiments, the pulling assembly also includes two second magnetic members, which are respectively arranged on the inner wall of the first sub-hole close to the driving member and the inner wall of the second sub-hole close to the driving member, and the two second magnetic members are respectively used to apply suction force toward the driving member to the two clamping parts, so that the two clamping parts are respectively opposite to the first sub-hole and the second sub-hole under the suction force of the first magnetic member and the two second magnetic members.
[0008] In some embodiments, the first sub-hole and the second sub-hole have a first guide surface and a second guide surface that are inclined on one side thereof and close to each other, respectively, and the first guide surface and the second guide surface are used to guide the two clamping parts when the two clamping parts are inserted into the first sub-hole and the second sub-hole, respectively.
[0009] In some embodiments, the pulling assembly includes a connecting member and a pulling member connected to each other, the driving member is connected to an end of the connecting member away from the pulling member, and the through hole is opened at an end of the pulling member away from the connecting member.
[0010] In some embodiments, the pulling assembly further includes a fixing member, wherein the fixing member is respectively connected to the connecting member and the pulling member to fix the pulling member and the connecting member.
[0011] In some embodiments, a positioning groove is formed on a side of the connecting member facing the pulling member, and the pulling member is disposed in the positioning groove.
[0012] In some embodiments, the pulling member includes a pulling portion and a connecting portion connected to each other, an end of the connecting portion away from the pulling portion is inserted into the positioning groove, and the through hole is opened at an end of the pulling portion away from the connecting portion, and along the first direction, the size of the cross-section of the pulling portion is smaller than the size of the cross-section of the connecting portion.
[0013] In some embodiments, along the direction from the pulling portion to the connecting portion, the size of the cross section of an end of the pulling portion away from the connecting portion gradually increases.
[0014] When using the above-mentioned testing mechanism to test whether the bonding strength of the connecting component relative to the workpiece meets the standard, the workpiece is set at a preset position, and then the driving member drives the pulling member to move in a direction close to the clamping member to insert the connecting component into the through hole. The driving member then applies a preset pulling force along a first direction and pulls the connecting component through the pulling member. If the connecting component is not pulled away from the workpiece, the bonding strength of the connecting component relative to the workpiece meets the standard. If the connecting component is pulled away from the workpiece, the bonding strength of the connecting component relative to the workpiece does not meet the standard.
[0015] In this application, the through hole of the drawing component is for the connection component to be inserted. Thus, when the driving component applies a preset pulling force in the first direction and pulls the connection component through the drawing component, the whole of the drawing component except the through hole area is stressed, resulting in a relatively large stress area of the drawing component. As a result, the drawing component is not easily broken during the drawing process, and the service life of the testing mechanism is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Some embodiments of the present application will be described in detail below with reference to the drawings.
[0047] Please refer to Figure 1, an embodiment of the present application provides a testing mechanism 100 for testing whether the adhesion strength between a connection component 300 bonded to a workpiece and the workpiece meets the standard. Among them, the workpiece can be the lower case, middle frame, etc. of electronic products such as notebook computers and tablet computers, and the connection component 300 can be a plug-in structure, snap structure, etc. bonded to the workpiece. For the convenience of understanding and description, in the embodiment of the present application, taking the workpiece as the lower case of a notebook computer and the connection component 300 as a snap structure bonded to the lower case of the notebook computer, and the connection component 300 is used to connect with the upper case of the notebook computer as an example, obviously, this is not a limitation on the embodiment of the present application.
[0048] Please refer to Figure 1 and Figure 2 , the testing mechanism 100 includes a pulling component 10 and a driving member 20.
[0049] The pulling component 10 is provided with a through hole 1221 for inserting the connection component 300. The driving member 20 is connected to the pulling component 10. The driving member 20 is used to apply a preset pulling force in the first direction and pull the connection component 300 through the pulling component 10 to judge whether the adhesion strength between the connection component 300 and the workpiece meets the standard according to the separation situation of the connection component 300 from the workpiece. Among them, the magnitude of the preset pulling force is set according to the magnitude of the required adhesion strength between the connection component 300 and the workpiece. In this embodiment, the first direction is Figure 1 the Z-axis direction shown.
[0050] When using the above-mentioned testing mechanism 100 to test whether the adhesion strength of the connection component 300 relative to the workpiece meets the standard, the workpiece is set at a preset position, and then the driving member 20 drives the pulling component 10 to move in the direction close to the connection component 300 so that the connection component 300 is inserted into the through hole 1221. The driving member 20 then applies a preset pulling force in the first direction and pulls the connection component 300 through the pulling component 10. Among them, when the driving member 20 drives the pulling component 10 to pull the connection component 300, if the connection component 300 is not pulled off from the workpiece, the adhesion strength of the connection component 300 relative to the workpiece meets the standard; if the connection component 300 is pulled off from the workpiece, the adhesion strength of the connection component 300 relative to the workpiece does not meet the standard. In the present application, the through hole 1221 of the pulling component 10 is for the connection component 300 to be inserted. Thus, when the driving member 20 applies a preset pulling force in the first direction and pulls the connection component 300 through the pulling component 10, the whole of the pulling component 10 except the area of the through hole 1221 is stressed, so that the stressed area of the pulling component 10 is larger, and further the pulling component 10 is not easily broken during the pulling process, improving the service life of the testing mechanism 100.
[0051] Please further refer to Figure 3, the connecting component 300 includes a small part 301 adhered to the workpiece and a clamping part 302 connected to the small part 301. The clamping part 302 has two oppositely arranged clamping portions 3021. The pulling component 10 has a separating portion 1222. The separating portion 1222 is located in the through hole 1221 and divides the through hole 1221 into a first sub-hole 12211 and a second sub-hole 12212 that are spaced apart along the second direction. The first sub-hole 12211 is for inserting one of the clamping portions 3021, and the second sub-hole 12212 is for inserting the other clamping portion 3021. The second direction is perpendicular to the first direction. Specifically, by providing the separating portion 1222 to divide the through hole 1221 into the first sub-hole 12211 and the second sub-hole 12212 that are spaced apart along the second direction, the first sub-hole 12211 and the second sub-hole 12212 correspond to the two clamping portions 3021 one by one, facilitating the pulling component 10 to simultaneously pull the two clamping portions 3021 of the clamping part 302, and further pulling the small part 301 adhered to the workpiece. The pulling component 10 simultaneously pulls the two clamping portions 3021 of the clamping part 302, enabling the clamping part 302 to be pulled more smoothly and reliably. The second direction is Figure 1 the Y-axis direction shown.
[0052] In this embodiment, the provision of the separating portion 1222 causes the separating portion 1222 to be stressed during the pulling test, further increasing the bearing capacity of the pulling component 10 and further reducing the probability of the pulling component 10 being pulled off.
[0053] In this embodiment, the driving member 20 is further configured to drive the pulling component 10 to move in a third direction so that the connecting component 300 is inserted into the through hole 1221 of the pulling component 10. The third direction is perpendicular to both the first direction and the second direction. Specifically, when testing whether the adhesion force of the connecting component 300 relative to the workpiece meets the standard, after the workpiece is set at a preset position, the driving member 20 drives the pulling component 10 to move in the third direction so that the pulling component 10 gradually approaches the connecting component 300 until the two clamping portions 3021 of the clamping part 302 are respectively inserted into the first sub-hole 12211 and the second sub-hole 12212, and then the driving member 20 applies a preset pulling force in the first direction and pulls the two clamping portions 3021 of the clamping part 302 through the pulling component 10. The third direction is Figure 1 the X-axis direction shown.
[0054] In this embodiment, the card member 302 is movably connected to the small member 301. The pulling component 10 further includes a first magnetic member 13. The first magnetic member 13 is disposed on the inner wall of the first sub-hole 12211 away from the second sub-hole 12212. The first magnetic member 13 is configured to apply a suction force towards the first magnetic member 13 to the two latching portions 3021. Specifically, since the card member 302 is movably connected to the small member 301, when the driving member 20 drives the pulling component 10 to move in the third direction, the two latching portions 3021 of the card member 302 may be misaligned with the first sub-hole 12211 and the second sub-hole 12212, resulting in the pulling component 10 directly hitting the two latching portions 3021 of the card member 302. By providing the first magnetic member 13 in this application, when the pulling component 10 moves in the third direction and approaches the connecting component 300, the two latching portions 3021 of the card member 302 are biased towards the direction where the first magnetic member 13 is located under the suction force of the first magnetic member 13, thereby preventing the card member 302 from moving relative to the small member 301 to an uncertain position or orientation, so that the two latching portions 3021 of the card member 302 are respectively aligned with the first sub-hole 12211 and the second sub-hole 12212, and further enabling the two latching portions 3021 of the card member 302 to be respectively inserted into the first sub-hole 12211 and the second sub-hole 12212. In this embodiment, the first magnetic member 13 may be, but is not limited to, a magnet; the card member 302 may be, but is not limited to, a circlip; the card member 302 is made of a ferromagnetic material, so that the card member 302 can be attracted by the first magnetic member 13.
[0055] In some other embodiments, the first magnetic member 13 may also be disposed on the inner wall of the second sub-hole 12212 away from the first sub-hole 12211. The first magnetic member 13 can also apply a suction force towards the first magnetic member 13 to the two latching portions 3021, thereby also achieving the effect that the two latching portions 3021 of the card member 302 are respectively aligned with the first sub-hole 12211 and the second sub-hole 12212. The embodiments of this application do not make specific limitations on this.
[0056] In this embodiment, the pulling component 10 further includes two second magnetic attracting members 14 which are respectively arranged on the inner walls of the first sub-hole 12211 and the second sub-hole 12212 close to the driving member 20. The two second magnetic attracting members 14 are respectively used to apply a suction force towards the driving member 20 to the two clamping portions 3021, so that the two clamping portions 3021 are respectively aligned with the first sub-hole 12211 and the second sub-hole 12212 under the suction force of the first magnetic attracting member 13 and the two second magnetic attracting members 14. Specifically, the first magnetic attracting member 13 applies a suction force towards the second direction to the two clamping portions 3021 of the clamping member 302, and the two second magnetic attracting members 14 respectively apply a suction force towards the first direction to the two clamping portions 3021 of the clamping member 302. Thus, the two clamping portions 3021 of the clamping member 302 both tend to the included angle direction of the first direction and the second direction. When the pulling component 10 approaches the connecting component 300 along the third direction, the two clamping portions 3021 of the clamping member 302 are respectively aligned with and inserted into the first sub-hole 12211 and the second sub-hole 12212. In this embodiment, the second magnetic attracting member 14 can be, but is not limited to, a magnet.
[0057] In one embodiment, the first direction is the vertical direction, and the second direction and the third direction are two mutually perpendicular directions in the horizontal direction. When using the above-mentioned testing mechanism 100 to test whether the adhesion strength of the connecting component 300 relative to the workpiece meets the standard, the workpiece is set at a preset position in the horizontal direction, and then the driving member 20 drives the pulling component 10 to approach the clamping member 302 along the third direction, so that the connecting component 300 is inserted into the through hole 1221. Then, the driving member 20 applies a preset pulling force in the vertical direction and pulls the connecting component 300 through the pulling component 10. In this way, it is convenient to carry out the pulling test.
[0058] Please refer to Figure 5The first sub-hole 12211 and the second sub-hole 12212 have a first guide surface 12213 and a second guide surface 12214 arranged obliquely on the side close to each other. The first guide surface 12213 and the second guide surface 12214 are used to guide the two clamping parts 3021 when the two clamping parts 3021 are inserted into the first sub-hole 12211 and the second sub-hole 12212. The angle between the extended surface of the first guide surface 12213 and the extended surface of the second guide surface 12214 is an acute angle. When the test mechanism 100 is working, the distance between the first guide surface 12213 and the second guide surface 12214 facing the connecting component 300 is smaller, that is, the size of the first sub-hole 12211 and the second sub-hole 12212 facing the connecting component 300 is larger, so that the first guide surface 12213 and the second guide surface 12214 can play a guiding role for the two clamping parts 3021. Thus, by providing the first guide surface 12213 and the second guide surface 12214, when the driving member 20 drives the pulling assembly 10 to approach the two clamping parts 3021 of the clamping member 302 along the third direction, the first guide surface 12213 and the second guide surface 12214 guide the two clamping parts 3021, so that the two clamping parts 3021 can be respectively inserted into the first sub-hole 12211 and the second sub-hole 12212. The first guide surface 12213 is the side wall of the partition 1222 facing the first sub-hole 12211, and the second guide surface 12214 is the side wall of the partition 1222 facing the second sub-hole 12212.
[0059] Please refer to Figure 1 , Figure 2 and Figure 4 In this embodiment, the drawing assembly 10 includes a connecting member 11 and a drawing member 12 connected to each other, the driving member 20 is connected to an end of the connecting member 11 away from the drawing member 12, and the through hole 1221 is provided at an end of the drawing member 12 away from the connecting member 11. In this embodiment, the connecting member 11 can be, but is not limited to, a flange. By providing the connecting member 11, it is convenient to realize the connection between the drawing member 12 and the driving member 20.
[0060] In this embodiment, the drawing assembly 10 further includes a fixing member 15, which is connected to the connecting member 11 and the drawing member 12 respectively, so as to fix the drawing member 12 and the connecting member 11. Specifically, the fixing member 15 may be, but is not limited to, a bolt, and the fixing member 15 passes through the connecting portion 121 of the connecting member 11 and extends into the connecting member 11, so as to realize the connection between the connecting member 11 and the drawing member 12. By providing the fixing member 15, it is convenient to realize the reliable fixation of the connecting member 11 and the drawing member 12.
[0061] In this embodiment, the number of the fixing members 15 is two or more, and the two or more fixing members 15 are respectively connected to the connecting member 11 and the pulling member 12 and are arranged at intervals, thereby improving the connection reliability of the connecting member 11 and the pulling member 12.
[0062] In this embodiment, the connecting member 11 and the pulling member 12 are detachably connected. Such a setting facilitates the replacement and repair of the pulling member 12.
[0063] Please refer to Figure 4 , in this embodiment, a positioning groove 111 is formed on one side of the connecting member 11 facing the pulling member 12, and the pulling member 12 is disposed in the positioning groove 111. Specifically, the setting of the positioning groove 111 positions the pulling member 12. In this way, when the pulling member 12 is placed in the positioning groove 111, the correctness of the position of the pulling member 12 relative to the connecting member 11 can be ensured, and it is convenient to accurately fix the pulling member 12 to the connecting member 11 through the fixing member 15.
[0064] In this embodiment, the pulling member 12 includes a pulling portion 122 and a connecting portion 121 connected to each other. One end of the connecting portion 121 away from the pulling portion 122 is inserted into the positioning groove 111, and a through hole 1221 is formed at one end of the pulling portion 122 away from the connecting portion 121. Along the first direction, the cross-sectional dimension of the pulling portion 122 is smaller than that of the connecting portion 121. Specifically, the cross-sectional dimension of the pulling portion 122 is set to be smaller, so that the space occupied by the pulling portion 122 is smaller, and thus when a pulling test is performed, the probability of interference between the pulling portion 122 and the workpiece is reduced.
[0065] In this embodiment, along the direction from the pulling portion 122 to the connecting portion 121, the cross-sectional dimension of one end of the pulling portion 122 away from the connecting portion 121 gradually increases. In this way, the space occupied by one end of the pulling portion 122 away from the connecting portion 121 is smaller, and thus when a pulling test is performed, the probability of interference between the pulling portion 122 and the workpiece can be further reduced.
[0066] The operation process of the testing mechanism 100 in the embodiment of the present application is generally as follows:
[0067] Place the workpiece bonded with the connection component 300 at a preset position, and drive the connecting piece 11 and the pulling piece 12 to move along the third direction by the driving piece 20, so that the pulling piece 12 gradually approaches the clamping piece 302 of the connection component 300. During this process, the first magnetic attraction piece 13 and the two second magnetic attraction pieces 14 apply suction forces to the two clamping portions 3021 of the clamping piece 302, so that the two clamping portions 3021 are respectively aligned with the first sub-hole 12211 and the second sub-hole 12212 of the pulling piece 12 under the suction forces of the first magnetic attraction piece 13 and the two second magnetic attraction pieces 14. Then, insert the two clamping portions 3021 into the first sub-hole 12211 and the second sub-hole 12212 respectively. Then, the driving piece 20 applies a preset pulling force along the first direction and pulls the clamping piece 302 and the small piece 301 through the pulling component 10. If the small piece 301 is separated from the workpiece under the action of the preset pulling force, it indicates that the bonding strength between this connection component 300 and the workpiece does not meet the standard. If the small piece 301 remains bonded to the workpiece under the action of the preset pulling force, it indicates that the bonding strength between this connection component 300 and the workpiece meets the standard.
[0068] The testing mechanism 100 provided by the embodiment of the present application opens a through hole 1221 on the pulling component 10, so that during the pulling test, the area of the pulling component 10 except the through hole 1221 is stressed, thereby increasing the stress area of the pulling component 10, so that the bearing capacity of the pulling component 10 is stronger, the pulling component 10 is not easily broken, and further the service life of the testing mechanism 100 is improved; by providing a partition portion 1222 to divide the through hole 1221 into a first sub-hole 12211 and a second sub-hole 12212 that are spaced apart along the second direction. In this way, the first sub-hole 12211 and the second sub-hole 12212 correspond to the two clamping portions 3021 one by one, which is convenient for the pulling component 10 to pull the two clamping portions 3021 of the clamping piece 302 at the same time, so as to pull the clamping piece 302 stably and reliably. And when performing the pulling test, the partition portion 1222 is also stressed, thereby further increasing the stress area of the pulling component 10; by providing the first magnetic attraction piece 13 and the two second magnetic attraction pieces 14, the two clamping portions 3021 are respectively aligned with the first sub-hole 12211 and the second sub-hole 12212 under the suction force, so as to facilitate the two clamping portions 3021 to accurately insert into the first sub-hole 12211 and the second sub-hole 12212; by providing the first guiding surface 12213 and the second guiding surface 12214, when the two clamping portions 3021 are respectively inserted into the first sub-hole 12211 and the second sub-hole 12212, they are guided by the first guiding surface 12213 and the second guiding surface 12214, so as to further facilitate the two clamping portions 3021 to accurately insert into the first sub-hole 12211 and the second sub-hole 12212; by providing the connecting piece 11 and the pulling piece 12 to be detachably connected, it is convenient to replace and repair the pulling piece 12; by opening a positioning groove 111 on the side of the connecting piece 11 facing the pulling piece 12, it is convenient to realize the positioning of the pulling piece 12 relative to the connecting piece 11.
[0069] It is obvious to those skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, and that the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present application is defined by the appended claims rather than the above description.
