For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0026] The following is a detailed description of the test equipment provided in the embodiment of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0027] Please refer to Figure 1-Figure 6 The test device disclosed in the embodiment of the present application includes a base 100, a positioning mechanism 200 and a test needle holder 300, wherein the base 100 serves as an installation base for the positioning structure and the test needle holder 300, the positioning mechanism 200 and the test needle holder 300 are both arranged on the base 100, the base 100 is used to carry a fixture 500, and the fixture 500 is used to place a product 600. This embodiment does not specifically limit the type of product 600; the positioning mechanism 200 is used to position the fixture 500 so that the test needle holder 300 is opposite to the product 600 carried by the fixture 500. When the test needle holder 300 is opposite to the product 600, the test needle holder 300 can test the product 600.

[0028] Alternatively, if Figure 2 As shown, the base 100 includes a base body 110 and a support plate 120, the support plate 120 is connected to the base body 110, and the plane where the support plate 120 is located is perpendicular to the support surface of the base body 110, the positioning mechanism 200 is installed on the base body 110, and the test needle seat 300 is slidably connected to the support seat. Further optionally, the test needle seat 300 and the support plate 120 are slidably connected through the second guide rail 310, that is, one of the test needle seat 300 and the support plate 120 is provided with a second slider, and the other is provided with a second slide rail, the second slide rail is slidably matched with the second slide rail, and the second slide rail and the second slider together form the second guide rail 310.

[0029] The positioning mechanism 200 includes a first pressing member 210 and a positioning member 240, and the first pressing member 210 is connected to the positioning member 240. Optionally, the first pressing member 210 can be directly connected to the positioning member 240, and when the first pressing member 210 is pressed and moved, it directly drives the positioning member 240 to move; the first pressing member 210 can also be indirectly connected to the positioning member 240 through other components, and when the first pressing member 210 is pressed and moved, it drives the positioning member 240 to move and rotate.

[0030] When the first pressing member 210 is in the first pressure state, the first pressing member 210 moves and drives the positioning member 240 to move, and the positioning member 240 extends into the positioning hole of the fixture 500 to lock the positioning member 240. When the first pressing member 210 is in the second pressure state, the positioning member 240 can be separated from the positioning hole to unlock the positioning member 240. Optionally, when the first pressing member 210 is in the second pressure state, the first pressing member 210 moves and triggers other components to drive the positioning member 240 to reset in the opposite direction, so that the positioning member 240 is separated from the positioning hole.

[0031] It should be noted that the “first compressed state” refers to the state when the first pressing member 210 is compressed before the positioning member 240 extends into the positioning hole of the fixture 500, and the “second compressed state” refers to the state when the first pressing member 210 is compressed after the positioning member 240 extends into the positioning hole of the fixture 500.

[0032] In the embodiment of the present application, the positioning mechanism 200 of the test equipment positions the fixture 500 only by pressing the first pressing member 210 with an external force. The positioning mechanism 200 does not require an external power source such as an air source or a power source, thereby getting rid of the industrial power source, saving power source, and no longer being restricted by the industrial power source. Therefore, the test equipment can be placed at any position as needed. Moreover, the operator does not need to control the power source such as the air source or the power source, and is not easily affected by the on-site working conditions, which is conducive to ensuring the safety of the operator.

[0033] In an alternative embodiment, reference Figure 3 and Figure 4 As shown, the positioning mechanism 200 also includes a first guide rod 220 and a first guide cylinder 230, and the first pressing member 210 can move relative to the base 100. Optionally, the first pressing member 210 can be slidably connected to the base 100. Further optionally, the first pressing member 210 and the base 100 can be slidably connected through a first guide rail 211, that is, one of the first pressing member 210 and the base 100 is provided with a first slider, and the other is provided with a first slide rail, the first slide rail is slidably matched with the first slider, and the first slide rail and the first slider together form the first guide rail 211.

[0034] The first guide rod 220 is rotatably connected with the first pressing member 210. Optionally, the first pressing member 210 is provided with a first axial hole, one end of the first guide rod 220 extends into the first axial hole, and the first guide rod 220 is rotatably matched with the first axial hole. Further optionally, the positioning mechanism 200 also includes a first bearing 270. The first bearing 270 can be a tapered roller bearing or other types of bearings. The first bearing 270 is located in the first axial hole, and the first bearing 270 is sleeved on the outside of the first guide rod 220. In this way, the friction force of the first guide rod 220 relative to the first pressing member 210 during the rotation process is reduced, which is conducive to the smooth rotation of the first guide rod 220. At the same time, the first pressing member 210 is prevented from rotating with the first guide rod 220.

[0035] The first guide cylinder 230 is connected to the base 100. Optionally, the first guide cylinder 230 can be directly connected to the base 100 or indirectly connected to the base 100. The position of the first guide cylinder 230 relative to the base 100 is fixed. The first guide rod 220 penetrates the first guide cylinder 230, and the first guide rod 220 and the first guide cylinder 230 are transmission-matched in the spiral direction of the first guide rod 220, that is, the first guide rod 220 can move relative to the first guide cylinder 230 along the spiral direction of the first guide rod 220, and the positioning member 240 is connected to the first guide rod 220.

[0036] When the first pressing member 210 is in the first pressed state, the first pressing member 210 moves and drives the first guide rod 220 to move, and the first guide rod 220 rotates relative to the first pressing member 210 , and the positioning member 240 moves with the first guide rod 220 and extends into the positioning hole of the fixture 500 .

[0037] In this way, when an external force presses the first pressing member 210, the first pressing member 210 moves under the force. Since the first pressing member 210 is connected to the first guide rod 220, the first guide rod 220 moves with the first pressing member 210. At the same time, since the first guide rod 220 and the first guide cylinder 230 are transmitted and matched in the spiral direction, and the position of the first guide cylinder 230 is fixed, the first guide rod 220 moves and rotates around its own axis. The positioning member 240 is connected to the first guide rod 220, so the positioning member 240 will also move and rotate with the first guide rod 220, so that it can smoothly extend into the positioning hole of the fixture 500, thereby realizing the positioning of the fixture 500.

[0038] In an optional embodiment, the positioning mechanism 200 further includes a first elastic member 250, and the first elastic member 250 is connected to the first guide rod 220. The first elastic member 250 may be a spring, a torsion spring or other elastic structure, and the embodiment of the present application does not limit the structure of the first elastic member 250.

[0039] When the first pressing member 210 is in the first pressure state, the first elastic member 250 is driven by the first guide rod 220 to produce elastic deformation due to the movement and rotation of the first guide rod 220; when the first pressing member 210 is in the second pressure state, the first elastic member 250 can restore the elastic deformation and drive the first guide rod 220 to reset.

[0040] Specifically, after the first pressing state of the first pressing member 210 is completed, that is, when the positioning member 240 extends into the positioning hole and the first pressing member 210 is no longer pressed, the first guide rod 220 is locked and the elastic deformation of the first elastic member 250 is constant; then, when the first pressing member 210 is in the second pressing state, that is, when the first pressing member 210 is pressed again, the first guide rod 220 is unlocked, and the first elastic member 250 further produces elastic deformation. When the pressing force disappears again, the first elastic member 250 restores the elastic deformation and drives the first guide rod 220 to reset.

[0041] In this way, the elastic force generated by the first elastic member 250 is used to directly drive the first guide rod 220 to reset, which is beneficial to improving the reset efficiency of the first guide rod 220 and shortening the reset time.

[0042] Of course, in other embodiments, the testing device may not be provided with the first elastic member 250 , and the first guide rod 220 may be reset in the reverse direction through other structures or with the help of external force.

[0043] In an optional embodiment, the first elastic member 250 includes a first torsion spring 251 and a first spring 252, both of which are sleeved on the outside of the first guide rod 220, the first end of the first torsion spring 251 is connected to the first guide rod 220, and the second end of the first torsion spring 251 is connected to the first guide cylinder 230. In this way, during the rotation of the first guide rod 220, the first end and the second end of the first torsion spring 251 approach or move away from each other in the circumferential direction of the first guide rod 220, and the first torsion spring 251 generates elastic deformation.

[0044] The positioning mechanism 200 further includes a fixing seat 260, which is connected to the base 100. Optionally, the fixing seat 260 may be directly connected to the base 100 or indirectly connected to the base 100. The fixing seat 260 is provided with a through hole for the first guide rod 220 to pass through. The first guide cylinder 230 and the positioning member 240 are respectively located on opposite sides of the fixing seat 260. The first end of the first spring 252 is connected to the fixing seat 260, and the second end of the first spring 252 is connected to the first guide rod 220. In this way, during the movement of the first guide rod 220, the first spring 252 is compressed or stretched, and the first spring 252 generates elastic deformation.

[0045] In this embodiment, the first elastic member 250 is provided with a first torsion spring 251 and a first spring 252 at the same time. The first torsion spring 251 is mainly used to drive the first guide rod 220 to rotate and reset, and the first spring 252 is mainly used to drive the first guide rod 220 to move and reset. Therefore, the combination of the first torsion spring 251 and the first spring 252 is more conducive to the rotational reset and movement reset of the first guide rod 220, and is conducive to the first guide rod 220 accurately restoring to its initial position.

[0046] Of course, in other embodiments, the first elastic member 250 may only be provided with the first torsion spring 251 or the first spring 252. Optionally, the first elastic member 250 may be a gas spring, which has high stiffness and adjustability and a large load range.

[0047] In an optional embodiment, if Figure 3 As shown, one of the first guide rod 220 and the first guide cylinder 230 is provided with a first spiral groove 231, and the other is provided with a first convex column 221, the first convex column 221 extends into the first spiral groove 231, and the first convex column 221 and the first spiral groove 231 are slidably matched. The first convex column 221 can be a cylinder or a cylinder of other shapes, and can slide along the first spiral groove 231. Optionally, the first guide rod 220 is provided with the first convex column 221, and the first guide cylinder 230 is provided with the first spiral groove 231; or, the first guide rod 220 is provided with the first spiral groove 231, and the inner wall surface of the first guide cylinder 230 is provided with the first convex column 221. In this way, through the matching structure of the first convex column 221 and the first spiral groove 231, the first guide rod 220 is moved relative to the first guide cylinder 230 along the spiral direction.

[0048] In a further embodiment, a first clamping groove 232 is also provided at the end of the first spiral groove 231, and the first clamping groove 232 is connected to the first spiral groove 231. When the first pressing member 210 is in the first pressure state, the first protrusion 221 can extend into the first clamping groove 232 to fix the first guide rod 220 relative to the first guide cylinder 230; when the first pressing member 210 is in the second pressure state, the first protrusion 221 is disengaged from the first clamping groove 232.

[0049] Specifically, when the first pressing member 210 is in the first pressure state, the first protrusion 221 slides in the first spiral groove 231. After the first pressure state of the first pressing member 210 is completed, the first guide rod 220 moves to the extreme position relative to the first guide cylinder 230, that is, the first protrusion 221 slides to the end of the first spiral groove 231, and the first protrusion 221 can change the movement direction to extend into the first clamping groove 232; when the first protrusion 221 extends into the first clamping groove 232, the first protrusion 221 is stuck, and the first protrusion 221 is locked. A guide rod 220 is locked, the position of the positioning member 240 is fixed, and the positioning member 240 remains in a state of continuously positioning the fixture 500; when the first pressing member 210 is in the second pressure state, the first protrusion 221 disengages from the first slot 232, and the first protrusion 221 extends into the first spiral groove 231, unlocking the first guide rod 220. After the second pressure state of the first pressing member 210 is completed, the first protrusion 221 slides in the first spiral groove 231 in the reverse direction, and the positioning member 240 also moves in the reverse direction to gradually disengage from the positioning hole.

[0050] In this embodiment, the first clamping groove 232 is provided to clamp the first convex column 221, so as to fix the positions of the first guide rod 220 and the positioning member 240, which is conducive to the positioning mechanism 200 to continuously position the fixture 500, thereby facilitating the testing of the product 600 on the fixture 500. Moreover, the matching structure of the first clamping groove 232 and the first convex column 221 is simple, and there is no need to set up an additional mechanism for fixing the first guide rod 220.

[0051] Of course, in other embodiments, the first spiral groove 231 may not be provided with the first clamping groove 232, and the positioning mechanism 200 may be provided with a separate mechanism for fixing the first guide rod 220 at the extreme position.

[0052] In an embodiment in which the positioning mechanism 200 includes a first elastic member 250, the first pressing member 210 is moved by being pressed, the first guide rod 220 rotates and moves relative to the first guide cylinder 230, the first protrusion 221 slides along the first spiral groove 231, and the first elastic member 250 produces elastic deformation; when the first guide rod 220 moves to the extreme position, the pressing force of the first pressing member 210 disappears, the first elastic member 250 recovers part of its deformation and drives the first guide rod 220 to move, so that the first protrusion 221 extends into the first slot 232, and the positions of the first guide rod 220 and the positioning member 240 are fixed. When the first pressing member 210 is pressed again, the first guide rod 220 moves again, the first protrusion 221 moves from the first slot 232 to the first spiral groove 231, and the first elastic member 250 further produces elastic deformation. After the pressing force of the first pressing member 210 disappears, the first elastic member 250 restores the elastic deformation and drives the first guide rod 220 to reset in the reverse direction, and the first protrusion 221 slides in the reverse direction along the first spiral groove 231.

[0053] In an optional embodiment, the positioning member 240 is a rigid structural member or other structure that cannot produce elastic deformation. In another embodiment, the positioning member 240 is an elastic positioning member, and when the first pressing member 210 is in the second pressure state, the first protrusion 221 moves from the first slot 232 to the first spiral slot 231, and the elastic positioning member produces elastic deformation. Optionally, the elastic positioning member can be an integrally formed elastic positioning rod.

[0054] It should be noted that the “first compressed state” refers to the state when the first pressing member 210 is compressed when the first protrusion 221 is located in the first spiral groove 231 , and the “second compressed state” refers to the state when the first pressing member 210 is compressed when the first protrusion 221 is located in the first slot 232 .

[0055] With such arrangement, during the process of the first boss 221 disengaging from the first slot 232, the elastic positioning member further generates elastic deformation, and the elastic positioning member accumulates elastic force. Subsequently, the elastic positioning member applies force to the fixture 500, which is beneficial for the elastic positioning member to disengage from the positioning hole of the fixture 500 in time during the subsequent resetting process of the first guide rod 220, thereby avoiding the situation where the positioning member 240 is stuck in the positioning hole and cannot be successfully reset.

[0056] In an optional embodiment, if Figure 3 and Figure 4 As shown, the elastic positioning member is a split structure, and the elastic positioning member includes a positioning pin 241, a first fastener 242 and a second elastic member 243. The first fastener 242 can be a screw, a screw or other components. The first fastener 242 penetrates the positioning pin 241 and extends into the first guide rod 220, and the first fastener 242 is threadedly matched with the first guide rod 220, that is, the positioning pin 241 is connected to the first guide rod 220 through the first fastener 242. Optionally, a threaded hole is provided at the end of the first guide rod 220, and the first fastener 242 extends into the threaded hole.

[0057] The second elastic member 243 may be, but is not limited to, a spring, and the present embodiment does not limit the structure of the second elastic member 243. The second elastic member 243 is sleeved on the outside of the first fastener 242, the first end of the second elastic member 243 is connected to the positioning pin 241, and the second end of the second elastic member 243 is connected to the first guide rod 220. Optionally, the first end of the second elastic member 243 may directly abut against the end of the first guide rod 220, and the second end of the second elastic member 243 may directly abut against the positioning pin 241; or, the first end of the second elastic member 243 is fixedly connected to the first guide rod 220 by welding or the like, and the second end of the second elastic member 243 is fixedly connected to the positioning pin 241 by welding or the like.

[0058] When the first pressing member 210 is in the second pressure state, the first guide rod 220 rotates relative to the first fastener 242, and the first guide rod 220 approaches the positioning pin 241, and the second elastic member 243 produces elastic deformation. Since the positioning pin 241 has positioned the fixture 500 at this time, the positioning pin 241 cannot continue to extend into the positioning hole, and the positions of the positioning pin 241 and the first fastener 242 are fixed. Then, the first guide rod 220 is threadedly engaged with the first fastener 242 during the movement, and the axial distance between the first guide rod 220 and the positioning pin 241 is shortened, and the second elastic member 243 is compressed or stretched.

[0059] In this way, when it is difficult to set up a separate positioning piece 240 with an elastic effect to position the fixture 500, an elastic positioning piece can be formed by cooperating with existing more conventional components, that is, the positioning pin 241, the first fastener 242 and the second elastic piece 243 are matched to achieve the above process, which can not only cooperate with the positioning hole of the fixture 500 through the positioning pin 241, but also generate corresponding elastic deformation through the second elastic piece 243.

[0060] In an optional embodiment, the number of the first guide cylinder 230 , the number of the first guide rod 220 and the number of the positioning member 240 are all one.

[0061] In another embodiment, the number of the first guide cylinder 230, the first guide rod 220 and the positioning member 240 is at least two, the first guide cylinder 230, the first guide rod 220 and the positioning member 240 correspond to each other one by one, each first guide rod 220 is arranged at intervals, the first pressing member 210 is rotatably connected to each first guide rod 220, and each positioning member 240 extends into a different positioning hole of the fixture 500. Optionally, the first pressing member 210 is arranged at intervals with a plurality of first shaft holes, each first guide rod 220 extends into each first shaft hole, each first guide rod 220 is rotatably matched with the corresponding first shaft hole, and the first bearing 270 is sleeved on the outside of each first guide rod 220.

[0062] By adopting this embodiment, when external force presses the first pressing member 210, multiple first guide rods 220 can be driven to move at the same time, thereby driving multiple positioning members 240 to move to extend into different positioning holes of the fixture 500, thereby positioning the fixture 500 at different positions, which is beneficial to improving the positioning accuracy of the fixture 500.

[0063] In an optional embodiment, if Figure 1As shown, the positioning mechanism 200 further includes at least two positioning ribs 280, each of which is arranged at intervals, and two of which are respectively used to contact two adjacent side surfaces of the fixture 500. Optionally, the positioning ribs 280 can be a strip structure, and the extension direction of the strip structure is the same as the extension direction of the side surface of the fixture 500, so that the positioning ribs 280 and the side surface of the fixture 500 are better fitted, thereby improving the accuracy of the initial positioning of the fixture 500.

[0064] Optionally, the fixture 500 may be a quadrilateral structure, and two adjacent side surfaces of the fixture 500 are perpendicular to each other, wherein two positioning ribs 280 are perpendicular to each other, and the fixture 500 may be preliminarily positioned by means of the two positioning ribs 280 .

[0065] According to this embodiment, before pressing the first pressing member 210 , at least two positioning ribs 280 are used to preliminarily position the fixture 500 , which is beneficial for the positioning member 240 to be aligned with the positioning hole of the fixture 500 , thereby facilitating the positioning member 240 to accurately extend into the positioning hole, thereby improving the positioning accuracy of the fixture 500 .

[0066] Of course, the structure of the preliminary positioning fixture 500 is not limited to the positioning rib 280 . In other embodiments, the positioning mechanism 200 may utilize other mechanisms to preliminarily position the fixture 500 .

[0067] In the solution of the present application, the test device also includes a driving mechanism 400, which is arranged on the base 100, and the driving mechanism 400 is connected to the test needle holder 300, and the driving mechanism 400 can drive the test needle holder 300 to move so that the test needle holder 300 is close to or away from the product 600. Among them, the driving mechanism 400 can be a driving member such as a cylinder, a linear module, etc. that can generate linear displacement. Optionally, after the fixture 500 completes the positioning process, the test needle holder 300 is located directly above the product 600, and the driving mechanism 400 can drive the test needle holder 300 to move downward or upward.

[0068] With this embodiment, the driving mechanism 400 is used to directly drive the test needle holder 300 to approach the product 600, so that the test needle holder 300 can test the product 600 easily, which is beneficial to improving the testing efficiency of the test needle holder 300.

[0069] Of course, in other embodiments, the test device may not be provided with the driving mechanism 400, and the test needle holder 300 can move by means of an external structure.

[0070] Alternatively, if Figure 1As shown, the test device further includes a position sensing device 800, which can be a position sensor or other detection device that can detect the position of the test needle holder 300. The position sensing device 800 is disposed on the base 100, and further optionally, the position sensing device 800 is disposed on the support plate 120. In this way, by relying on the position sensing device 800, it is detected whether the test needle holder 300 has moved to a suitable position, and the driving mechanism 400 is promptly controlled to stop driving the test needle holder 300 to move, so as to avoid excessive movement of the test needle holder 300.

[0071] In an alternative embodiment, reference Figure 5 and Figure 6 As shown, the driving mechanism 400 includes a second pressing member 410, which can move relative to the base 100, and the second pressing member 410 is connected to the test needle holder 300. Optionally, the second pressing member 410 can be directly connected to the test needle holder 300, and when the second pressing member 410 is pressed and moved, it directly drives the test needle holder 300 to move; the second pressing member 410 can also be indirectly connected to the test needle holder 300.

[0072] When the second pressing member 410 is in the third pressure state, the second pressing member 410 moves and drives the test needle holder 300 to move in the first direction so that the test needle holder 300 is close to the product 600; when the second pressing member 410 is in the fourth pressure state, the test needle holder 300 can move in the second direction so that the test needle holder 300 is away from the product 600, and the first direction and the second direction are opposite. Optionally, when the second pressing member 410 is in the fourth pressure state, the second pressing member 410 moves and triggers other components to drive the test needle holder 300 to reset in the reverse direction, so that the test needle holder 300 moves in the reverse direction.

[0073] With this embodiment, the test needle holder 300 is moved by pressing the second pressing member 410 with an external force, and the driving mechanism 400 does not need an external power source such as an air source or a power source, thereby further saving power sources. The test equipment is no longer restricted by industrial power sources, further reducing the requirements for placement location, and further benefiting the safety of the operator.

[0074] In a further embodiment, the driving mechanism 400 further comprises a second guide rod 420 and a second guide cylinder 430, the second guide rod 420 is rotatably connected to the second pressing member 410, and optionally, the second pressing member 410 is provided with a second axial hole, one end of the second guide rod 420 extends into the second axial hole, and the second guide rod 420 is rotatably matched with the second axial hole. The second guide cylinder 430 is connected to the base 100, and optionally, the second guide cylinder 430 can be directly connected to the base 100, or can be indirectly connected to the base 100, in short, the position of the second guide cylinder 430 relative to the base 100 is fixed. The second guide rod 420 penetrates the second guide cylinder 430, and the second guide rod 420 and the second guide cylinder 430 are transmission matched in the spiral direction of the second guide rod 420, that is, the second guide rod 420 can move relative to the second guide cylinder 430 along the spiral direction of the second guide rod 420.

[0075] The test needle holder 300 is rotatably connected to the second guide rod 420. Optionally, the drive mechanism 400 further includes a second fastener 460, which can be a screw, a screw or other components, and the test needle holder 300 is provided with an opening, and the second fastener 460 passes through the opening and extends into the end of the second guide rod 420, so that the second fastener 460 is fixedly connected to the second guide rod 420, and the second fastener 460 is rotatably matched with the opening of the test needle holder 300. Further optionally, the drive mechanism 400 further includes a second bearing 450, which can be a tapered roller bearing or other types of bearings, and the second bearing 450 is located in the opening, and the second bearing 450 is sleeved on the outside of the second fastener 460. In this way, the friction force of the second fastener 460 during the rotation relative to the test needle seat 300 is reduced by relying on the second bearing 450, which is conducive to the smooth rotation of the second fastener 460 relative to the test needle seat 300 and prevents the test needle seat 300 from rotating with the second fastener 460, which is conducive to the smooth movement of the test needle seat 300.

[0076] When the second pressing member 410 is in the third pressed state, the second pressing member 410 moves and drives the second guide rod 420 to move, and the second guide rod 420 rotates relative to the second pressing member 410 , and the second guide rod 420 drives the test needle holder 300 to move, so that the test needle holder 300 is close to the product 600 .

[0077] In this way, when the second pressing member 410 is pressed by an external force, the second pressing member 410 is moved by the force. Since the second pressing member 410 is connected to the second guide rod 420, the second guide rod 420 moves with the second pressing member 410. At the same time, the second guide rod 420 and the second guide cylinder 430 are driven and matched in the spiral direction, and the position of the second guide cylinder 430 is fixed, so the second guide rod 420 will rotate around its own axis while moving. The test needle holder 300 is rotatably connected to the second guide rod 420, so the test needle holder 300 moves with the second guide rod 420, so that it can smoothly approach the product 600 to test the product 600.

[0078] In an optional embodiment, the driving mechanism 400 further includes a third elastic member 440, and the third elastic member 440 is connected to the second guide rod 420. The third elastic member 440 may be a spring, a torsion spring or other elastic structure, and the embodiment of the present application does not limit the structure of the third elastic member 440.

[0079] When the second pressing member 410 is in the third pressure state, the third elastic member 440 is driven by the second guide rod 420 to produce elastic deformation due to the movement and rotation of the second guide rod 420; when the second pressing member 410 is in the fourth pressure state, the third elastic member 440 can restore the elastic deformation and drive the second guide rod 420 to reset.

[0080] Specifically, after the third pressure state of the second pressing member 410 is completed, that is, when the test needle seat 300 is close to the product 600 and the second pressing member 410 is no longer pressurized, the second guide rod 420 is locked, and the elastic deformation of the third elastic member 440 is constant; then, when the second pressing member 410 is in the fourth pressure state, that is, when the second pressing member 410 is pressurized again, the second guide rod 420 is unlocked, and the third elastic member 440 further produces elastic deformation, and when the pressing force disappears again, the third elastic member 440 restores the elastic deformation and drives the second guide rod 420 to reset.

[0081] In this way, the elastic force generated by the third elastic member 440 is used to directly drive the second guide rod 420 to reset, which is beneficial to improving the reset efficiency of the second guide rod 420 and shortening the reset time.

[0082] Of course, in other embodiments, the testing device may not be provided with the third elastic member 440, and the second guide rod 420 may be reset in the reverse direction through other structures or with the help of external force.

[0083] In a further embodiment, Figure 5As shown, the third elastic member 440 includes a second torsion spring 441 and a second spring 442, both of which are sleeved on the outside of the second guide rod 420, the first end of the second torsion spring 441 is connected to the second guide rod 420, and the second end of the second torsion spring 441 is connected to the second guide cylinder 430. In this way, during the rotation of the second guide rod 420, the first end and the second end of the second torsion spring 441 approach or move away from each other in the circumferential direction of the second guide rod 420, and the second torsion spring 441 generates elastic deformation.

[0084] The first end of the second spring 442 is a fixed end, and the second end of the second spring 442 is connected to the second guide rod 420 . Thus, during the movement of the second guide rod 420 , the second spring 442 is compressed or stretched, and the second spring 442 undergoes elastic deformation.

[0085] In this embodiment, the third elastic member 440 is provided with a second torsion spring 441 and a second spring 442 at the same time. The second torsion spring 441 is mainly used to drive the second guide rod 420 to rotate and reset, and the second spring 442 is mainly used to drive the second guide rod 420 to move and reset. Therefore, the combination of the second torsion spring 441 and the second spring 442 is more conducive to the rotational reset and movement reset of the second guide rod 420, and is conducive to the second wire rod accurately restoring to its initial position.

[0086] Of course, in other embodiments, the third elastic member 440 may also only be provided with the second torsion spring 441 or the second spring 442. Optionally, the third elastic member 440 may be a gas spring, which has strong stiffness and adjustability and a large load range.

[0087] In an optional embodiment, one of the second guide rod 420 and the second guide cylinder 430 is provided with a second spiral groove 431, and the other is provided with a second convex column 421, the second convex column 421 extends into the second spiral groove 431, and the second convex column 421 and the second spiral groove 431 are slidably matched. The second convex column 421 can be a cylinder or a cylinder of other shapes, and can slide along the second spiral groove 431. Optionally, the second guide rod 420 is provided with a second convex column 421, and the second guide cylinder 430 is provided with a second spiral groove 431; or, the second guide rod 420 is provided with a second spiral groove 431, and the inner wall surface of the second guide cylinder 430 is provided with a second convex column 421. In this way, through the matching structure of the second convex column 421 and the second spiral groove 431, the second guide rod 420 is moved relative to the second guide cylinder 430 along the spiral direction.

[0088] In a further embodiment, a second clamping groove 432 is also provided at the end of the second spiral groove 431, and the second clamping groove 432 is connected to the second spiral groove 431. When the second pressing member 410 is in the third pressure state, the second protrusion 421 can extend into the second clamping groove 432 to fix the second guide rod 420 relative to the second guide cylinder 430; when the second pressing member 410 is in the fourth pressure state, the second protrusion 421 is disengaged from the second clamping groove 432.

[0089] Specifically, when the second pressing member 410 is in the third pressure state, the second protrusion 421 slides in the second spiral groove 431. After the first pressure state of the second pressing member 410 is completed, the second guide rod 420 moves to the extreme position relative to the second guide cylinder 430, that is, when the second protrusion 421 slides to the end of the second spiral groove 431, the second protrusion 421 can change the movement direction to extend into the second slot 432; when the second protrusion 421 extends into the second slot 432, the second protrusion 421 and the second guide rod 420 are stuck, the position of the test needle holder 300 is fixed, and the test needle holder 300 starts to test the product 600. When the second pressing member 410 is in the fourth pressure state, the second protrusion 421 disengages from the second slot 432, and the second protrusion 421 extends into the second spiral groove 431 to unlock the second guide rod 420. After the fourth pressure state of the second pressing member 410 is completed, the second protrusion 421 slides in the second spiral groove 431, and the test needle seat 300 also moves in the opposite direction to move away from the product 600.

[0090] In this embodiment, the second guide rod 420 and the test needle holder 300 are fixed by providing the second clamping groove 432 to clamp the second protrusion 421, which is conducive to maintaining the test needle holder 300 in the test state. In addition, the matching structure of the second clamping groove 432 and the second protrusion 421 is simple, and no additional mechanism for fixing the test needle holder 300 is required.

[0091] Of course, in other embodiments, the second spiral groove 431 may not be provided with the second clamping groove 432 , and the driving mechanism 400 may be provided with a separate mechanism for fixing the second guide rod 420 at the extreme position.

[0092] In an embodiment in which the driving mechanism 400 includes a third elastic member 440, the second pressing member 410 is moved by being pressed, the second guide rod 420 rotates and moves relative to the second guide cylinder 430, the second boss 421 slides along the second spiral groove 431, and the third elastic member 440 produces elastic deformation; when the second guide rod 420 moves to the extreme position, the pressing effect of the second pressing member 410 disappears, the third elastic member 440 recovers part of the deformation and drives the second guide rod 420 to move, so that the second boss 421 extends into the second slot 432, and the positions of the second guide rod 420 and the test needle seat 300 are fixed. When the second pressing member 410 is pressed again, the second guide rod 420 moves again, the second protrusion 421 moves from the second slot 432 to the second spiral groove 431, and the third elastic member 440 further produces elastic deformation. After the pressing force of the second pressing member 410 disappears, the third elastic member 440 restores the elastic deformation and drives the second guide rod 420 to reset in the opposite direction, and the second protrusion 421 slides in the opposite direction along the second spiral groove 431.

[0093] In an optional embodiment, if Figure 1 As shown, the test device also includes a first packaging shell 710 and a second packaging shell 720. The other components of the positioning mechanism 200 except the positioning rib 280 are encapsulated in the first packaging shell 710, and the first pressing piece 210 extends out of the first packaging shell 710. The first pressing piece 210 is slidably connected to the first packaging shell 710 through the first guide rail 211. The driving mechanism 400 is encapsulated in the second packaging shell 720, and the second pressing piece 410 extends out of the second packaging shell 720, and the end of the second spring 442 is lower than the second packaging shell 720.

[0094] In this way, the components of the positioning mechanism 200 except the positioning rib 280 are packaged as an integral module through the first packaging shell 710, and the first packaging shell 710 can directly fix the module to the base 100. Similarly, the driving mechanism 400 is also packaged as an integral module through the second packaging shell 720, and the second packaging shell 720 can directly fix the module to the base 100 without installing each component one by one.
