[0033] The workpiece needs to be placed in the tray 400 for support and fixation during the compression molding process of the mobile phone camera module, so as to facilitate the alignment and downward pressing of the workpiece by the pressing head. The force for fixing the workpiece is provided by the spring 420. The insufficient clamping force caused by the decrease of the spring force may cause the workpiece to be loose or warped, thereby affecting the compression molding precision. Therefore, the spring force of the spring 420 needs to be regularly inspected. Since the spring force of the spring 420 is related to the deformation amount thereof, manual measurement is difficult to control the stroke and the pushing direction, thereby affecting the measurement accuracy.

[0034] It can be understood that, with reference to Figures 1 to 7 The elastic force measuring device of the utility model, including base 100, positioning mechanism 200 and measuring mechanism 300, positioning mechanism 200 is used for supporting and fixing tray 400;Measuring mechanism 300 and positioning mechanism 200 are respectively arranged on the opposite sides of base 100 along the longitudinal direction, measuring mechanism 300 includes support plate 310, sliding seat 320, push-pull force meter 330 and transverse movement assembly 340, sliding seat 320 is slidably connected to base 100, transverse movement assembly 340 is used for driving sliding seat 320 to move laterally, support plate 310 is slidably connected to sliding seat 320, push-pull force meter 330 is fixedly arranged on support plate 310, the probe of push-pull force meter 330 is arranged along the longitudinal direction, support plate 310 can move along the longitudinal direction to the direction close to positioning mechanism 200, the side wall of sliding seat 320 is provided with limiting block 321, the side wall of sliding seat 320 is provided with abutment block 311, abutment block 311 can abut against limiting block 321 to limit the movement of support plate 310 to the direction close to positioning mechanism 200.

[0035] When measuring, tray 400 is fixedly placed in positioning mechanism 200, sliding seat 320 is driven to move laterally by transverse movement assembly 340, and support plate 310 and push-pull force meter 330 are driven to move laterally, until the probe of push-pull force meter 330 and one of the push rods 440 are aligned along the same axial direction, then support plate 310 is moved along the longitudinal direction to the direction close to positioning mechanism 200 by pushing, since the probe of push-pull force meter 330 is arranged along the longitudinal direction, the probe of push-pull force meter 330 can push the push rod 440 along the same axial direction to compress the spring 420, thereby measuring the spring force of the spring 420, which can reduce the possibility of deviation of the pushing direction, and abutment block 311 abuts against limiting block 321 to limit the movement of support plate 310 to the direction close to positioning mechanism 200, which can control the pushing stroke of push-pull force meter 330, thereby improving the measurement accuracy. In addition, sliding seat 320 is driven to move laterally by transverse movement assembly 340, so that the probe of push-pull force meter 330 can be aligned with different push rods 440 respectively, to measure the spring force of different springs 420 in the same tray 400 one by one, which can improve the convenience of measurement.

[0036] It should be noted that the tray 400 is provided with a plurality of springs 420 and a plurality of push rods 440, and one push rod 440 corresponds to a plurality of springs 420. The probe of the push-pull force meter 330 can be used to push the different push rods 440 one by one to measure the elastic force of the different springs 420. Therefore, the slide 320 is driven to move laterally by the lateral movement assembly 340, so that the probe of the push-pull force meter 330 can be aligned with the different push rods 440 respectively to measure the elastic force of the different springs 420 in the same tray 400 one by one, thereby improving the convenience of measurement.

[0037] After the slide 320 is driven to move laterally to the preset position by the lateral movement assembly 340, the position of the slide 320 can be fixed by using bolts or pins as fasteners to improve the measurement accuracy.

[0038] The base 100 is provided with a guide rail 110 arranged in the lateral direction, and the slide 320 is slidingly connected to the guide rail 110. The slide 320 is guided to move laterally by the guide rail 110, thereby improving the stability of the movement of the slide 320.

[0039] It can be understood that, referring to Figure 1 and Figure 2 , the measuring mechanism 300 further comprises a micrometer 350, the fixed end of the micrometer 350 is fixedly arranged on the limiting block 321, the movable end of the micrometer 350 can be extended or retracted towards the abutting block 311, and the abutting block 311 can abut against the movable end of the micrometer 350 to limit the movement of the support plate 310 towards the positioning mechanism 200. Since the fixed end of the micrometer 350 is fixedly arranged on the limiting block 321, and the abutting block 311 can abut against the movable end of the micrometer 350 to limit the movement of the support plate 310 towards the positioning mechanism 200, the stroke distance of the abutting block 311 can be adjusted by extending or retracting the movable end of the micrometer 350 towards the abutting block 311, thereby adjusting the stroke distance of the support plate 310 moving with the push-pull force meter 330. The push stroke can be adjusted as needed, and the stroke control accuracy can be improved to improve the measurement accuracy.

[0040] It can be understood that, referring to Figures 1 to 4The transverse moving assembly 340 comprises a rotating shaft 341, a gear 342 and a rack 343. The rotating shaft 341 is rotatably connected to the sliding base 320 and longitudinally arranged. The gear 342 is fixedly sleeved on the rotating shaft 341. The rack 343 is fixedly arranged on the base 100 in a transverse direction and engaged with the gear 342. Since the rotating shaft 341 is rotatably connected to the sliding base 320 and longitudinally arranged, the gear 342 is fixedly sleeved on the rotating shaft 341, and the rack 343 is fixedly arranged on the base 100 in a transverse direction, the rotating shaft 341 is rotated to drive the gear 342 to rotate, and the gear 342 is engaged with the rack 343 to drive the rotating shaft 341 to move in a transverse direction, thereby driving the sliding base 320 to move in a transverse direction and driving the support plate 310 and the push-pull force gauge 330 to move in a transverse direction. The stability of the transverse movement of the push-pull force gauge 330 can be improved, and the accuracy of the transverse position adjustment of the push-pull force gauge 330 can be improved.

[0041] Specifically, referring to Figures 1 to 4 , one end of the rotating shaft 341 away from the positioning mechanism 200 is provided with a hand wheel 344. The hand wheel 344 is convenient for the operator to rotate the rotating shaft to improve the convenience of transverse position adjustment.

[0042] It can be understood that, referring to Figures 1 to 3 , the sliding base 320 is fixedly provided with a quick clamp 360. The movable end of the quick clamp 360 is connected to the support plate 310. The quick clamp 360 is used to drive the support plate 310 to move in a longitudinal direction towards the positioning mechanism 200, and the quick clamp 360 can lock the position of the support plate 310 to make the abutting block 311 abut against the limiting block 321. During measurement, the handle of the quick clamp 360 is pulled to a horizontal position to drive the support plate 310 to move in a longitudinal direction towards the positioning mechanism 200 until the abutting block 311 abuts against the limiting block 321. The position of the support plate 310 is locked by using the dead point clamping principle of the quick clamp 360 to make the abutting block 311 abut against the limiting block 321. The position stability of the push-pull force gauge 330 during measurement can be improved, and the possibility of the position movement of the push-pull force gauge 330 due to the reaction force of the push rod 440 can be reduced, thereby improving the measurement accuracy.

[0043] It should be noted that when the test is completed, the handle of the quick clamp 360 is pulled to a vertical position to release the locking state of the quick clamp 360, so that the support plate 310 can move in a longitudinal direction away from the positioning mechanism 200.

[0044] It can be understood that, referring to Figure 1 and Figure 2The upper end face of the support plate 310 is provided with three positioning blocks 312, and a positioning groove 313 is formed between the three positioning blocks 312. The push-pull force gauge 330 can be clamped into the positioning groove 313 to position the push-pull force gauge 330. Since the positioning groove 313 is formed between the three positioning blocks 312, the position of the push-pull force gauge 330 can be conveniently positioned by clamping the push-pull force gauge 330 into the positioning groove 313, and the horizontal position deviation of the push-pull force gauge 330 during measurement can be reduced to improve the measurement accuracy.

[0045] It should be noted that one of the positioning blocks 312 abuts against one side of the push-pull force gauge 330 away from the probe, and the other two positioning blocks 312 abut against the transversely opposite two sides of the push-pull force gauge 330, respectively.

[0046] Specifically, referring to Figure 2 , the upper end face of the support plate 310 is provided with a first magnet 314 for magnetically attracting the push-pull force gauge 330. The vertical position of the push-pull force gauge 330 can be positioned by the first magnet 314 magnetically attracting the push-pull force gauge 330, which can reduce the possibility of the push-pull force gauge 330 being separated from the positioning groove 313, and can reduce the vertical position deviation of the push-pull force gauge 330 during measurement to improve the measurement accuracy.

[0047] It can be understood that, referring to Figure 1 and Figure 2 , the positioning mechanism 200 includes a support seat 210, and the upper end face of the support seat 210 is provided with a plurality of positioning pins 221. The positioning pins 221 can be inserted into the positioning holes 410 of the tray 400 to position the tray 400. The horizontal position of the tray 400 can be fixed by supporting the tray 400 by the support seat 210 and inserting the positioning pins 221 into the positioning holes 410 of the tray 400, which can facilitate the disassembly and fixation of the tray 400.

[0048] It should be noted that the support seat 210 includes two support blocks arranged symmetrically along the transverse direction on the base 100, and the two support blocks can be used to support the tray 400.

[0049] Specifically, referring to Figure 1 , Figure 2 and Figure 5The positioning mechanism 200 further comprises a rotating plate 220, which is rotationally connected to the support base 210, and a plurality of positioning pins 221 are protrusively arranged on opposite sides of the rotating plate 220, and the side of the rotating plate 220 can abut against the support base 210 to limit the rotation of the rotating plate 220. Since the plurality of positioning pins 221 are protrusively arranged on the opposite sides of the rotating plate 220, the opposite sides of the rotating plate 220 can support the fixing of the tray 400, and by rotating the rotating plate 220, one side of the rotating plate 220 faces upward and the other side abuts against the support base 210, so that the support and fixation of the tray 400 of different models and sizes can be adapted, thereby improving the applicability of the elastic force measuring device.

[0050] It should be noted that the upper end surface of the support base 210 is provided with a clamping groove 212, and the rotating plate 220 can be embedded in the clamping groove 212, when one side of the rotating plate 220 abuts against the bottom wall of the clamping groove 212, the opposite side of the rotating plate 220 is flush with the upper end surface of the support base 210, thereby supporting the tray 400.

[0051] It should be noted that the arrangement positions of the positioning pins 221 on the opposite sides of the rotating plate 220 can be different, thereby being able to adapt to the support and fixation of the tray 400 of different models and sizes.

[0052] Specifically, referring to Figure 1 、 Figure 2 and Figure 5 , the upper end surface of the support base 210 is provided with a second magnet 211, and the opposite sides of the rotating plate 220 are each provided with a third magnet 222, and the second magnet 211 can attract the third magnet 222 to position the rotating plate 220. Since the upper end surface of the support base 210 is provided with the second magnet 211, and the opposite sides of the rotating plate 220 are each provided with the third magnet 222, when the rotating plate 220 is rotated to a position where one side faces upward and the other side abuts against the support base 210, the second magnet 211 attracts the third magnet 222, so that the side of the rotating plate 220 tightly abuts against the upper end surface of the support base 210, thereby positioning the overturning position of the rotating plate 220, which can reduce the possibility of the tray 400 shaking due to the overturning of the rotating plate 220, and improve the position stability of the tray 400.
