In this process, the measurement value is read by manual visual reading, and the transcription process of data is also prone to errors due to manual factors. In view of this problem, digital measurement tape measures have appeared on the market, which convert the distance of the tape pulled out into a digital measurement result through various principles (such as capacitive grid, infrared, etc.), and then output the result to the information / digital system through various data transmission means (such as Bluetooth, WIFI, serial port, etc.).

[0045] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0046] Example 1

[0047] To address the problems existing in the prior art, this invention provides an automated testing device for digital measuring tapes.

[0048] like Figure 1 The image shows a prior art leather measuring tape 6, which includes a tape body 61 and a tape 62. The tape body 61 has an internal cavity and an opening that connects the cavity to the outside. The tape 62 is wound inside the cavity, with one end extending from the opening as a tap. When the tap is pulled outwards, the tape 62 wound inside the tape body 61 can be pulled out. Traditional leather measuring tapes 6 have graduations on the tape. Starting from the tap, as the tape 62 is gradually stretched, the graduations on the tape at the opening indicate the length of the object being measured. To facilitate data recording, in addition to directly visually viewing the scale on the measuring tape 62, existing technologies have also invented digital measuring tapes. These digital tape measures convert the distance the tape 62 is pulled out into digital measurement results using various principles (such as capacitive gratings and infrared technology). The results are then output to an information / digital system via various data transmission methods (such as Bluetooth, Wi-Fi, and serial ports). A recording button 63 is provided on the tape body 61. When the tape 62 is pulled to a predetermined position, pressing the recording button 63 records the current tape length and stores it in the relevant system. The digital measuring tape 6 effectively avoids errors or incorrect recording caused by manual readings, improving the accuracy of data measurement.

[0049] However, the above-mentioned leather tape 6 also has certain problems. In actual production process, it is necessary to ensure that the leather tape 6 maintains consistent accuracy under different pulling speeds, and to avoid the problem of inaccurate reading caused by too fast pulling of the leather tape 6. In addition, the leather tape 6 generally has an automatic retraction function to facilitate use. The automatic retraction function is often damaged due to high-intensity use, or due to differences in the use scenarios of the leather tape 6, the pulling angle of the tape 62 is different during the pulling and retraction processes, and the tape 62 and the opening position are prone to mutual friction to generate debris, which falls into the inside of the ruler body 61 and also affects the measurement accuracy of the leather tape. Therefore, it is necessary to invent a test device capable of durability testing of the leather tape 6.

[0050] In order to facilitate the description of the device, as shown in Figure 2 , first, the direction of the device is described. The first direction is A1A2 direction, specifically the length direction of the slide rail 11; the second direction is B1B2 direction, specifically the width direction of the slide rail 11; the third direction is C1C2 direction, specifically the direction of gravity; the first direction, the second direction and the third direction intersect with each other.

[0051] As shown in Figure 2 , Figure 3 , it is an automatic testing device for leather tape, which comprises a limiting assembly 1. In this embodiment, the limiting assembly 1 comprises a slide rail 11 and a plurality of fixed blocks 12. The slide rail 11 is in a straight line form, and the slide rail 11 is provided with opposite first end 111 and second end 112 along the first direction. A plurality of fixed blocks 12 are distributed along the first direction. The plurality of fixed blocks 12 can be equally spaced or unequally spaced.

[0052] As shown in Figure 4 , the bottom of the fixed block 12 is provided with a fixed seat 123, and the top surface of the fixed seat 123 is provided with two groove walls 122. The two groove walls 122 are respectively located on both sides of the slide rail 11 along the second direction, and the two groove walls 122 are both upwardly extended. The two groove walls 122 form a limiting groove 121 therebetween, and the slide rail 11 is accommodated in the limiting groove 121. The width of the limiting groove 121 is equal to or slightly greater than the width of the slide rail 11. The groove wall 122 is provided with a fixed screw 124, which penetrates the groove wall 122 and abuts against the side surface of the slide rail 11, so that the fixed block 12 and the slide rail 11 can be fixed with each other. The width of the fixed seat 123 is greater than the width between the outer surfaces of the two groove walls 122, and the two sides of the fixed seat 123 extend outwardly to form a protruding portion 126. The protruding portion 126 is provided with a fixed screw hole 125, so that the fixed block 12 can be fixed with the components (such as support frame, test bench) of the external environment, thereby assisting in fixing the slide rail 11.

[0053] To test the precision and durability of the tape measure 6, the tape 62 needs to be repeatedly pulled out of the tape body 61 at different speeds and the measurement readings of the tape measure 6 are recorded. As shown in Figure 2 The first clamping assembly 2 is used to fix the tape body of the tape measure 6, and the first clamping assembly 2 is located at one end (in this embodiment, specifically the second end 112, and those skilled in the art can know that it can also be arranged at the first end 111, and the present application does not limit this) of the sliding rail 11. The second clamping assembly 3 is used to connect with the tap of the tape 62, and the second clamping assembly 3 can slide along the sliding rail 11. When the second clamping assembly 3 slides towards the first end 111 (that is, slides in a direction away from the first clamping assembly 2), the tape 62 is pulled out of the tape body 61 by the first clamping assembly; when the second clamping assembly 3 slides towards the second end 112 (that is, slides in a direction close to the first clamping assembly 2), the tape 62 is retracted into the inside of the tape body 61. In the actual test process, only the first clamping assembly 3 needs to be continuously driven to reciprocate, so that the tape can be continuously pulled out from the inside of the tape body.

[0054] As shown in Figure 5 The second clamping assembly 3 specifically includes a sliding part 31 and a connecting part 32. The sliding part 31 specifically includes a first connecting block 311 and two ball slides 312. The two ball slides 312 are respectively located on both sides of the first connecting block 311 and are fixedly connected with the first connecting block 311. The two ball slides 312 also respectively match the shape of the two side edges of the sliding rail 11 in the second direction, so that the sliding part 31 will not fall off the sliding rail 11 during sliding along the sliding rail 11. The top surface of the first connecting block 311 and the top surfaces of the two ball slides 312 are located on the same horizontal plane, forming a fixed platform that can carry the connecting part 32. The bottom of the connecting part 32 is fixedly connected with the sliding part 31. In this embodiment, the connecting part 32 and the sliding part 31 are fixedly connected with each other by screws, and can also be fixedly connected with each other by other connection methods, such as welding, clamping, glue connection, etc., which will not be described in detail in this embodiment. The connecting part 32 includes a second connecting block 321 extending in the third direction, a third connecting block 322 extending in the first direction, and a first clamping block 323. The bottom of the second connecting block 321 is fixedly connected with the top surface of the sliding part 31. The first end of the third connecting block 322 in the first direction is fixedly connected with the top end of the second connecting block 321. The first clamping block 323 and the third connecting block 322 are stacked in the third direction. The first clamping block 323 and the third connecting block 322 are connected by screws. When the screws are tightened, the first clamping block 323 and the third connecting block 322 are close to each other and clamped. When the screws are loosened, the first clamping block 323 and the third connecting block 322 are separated to form a gap. When the first clamping block 323 and the third connecting block 322 are clamped, they can be fixedly connected with the tap of the tape 62.

[0055] As Figure 6 shown, in order to drive the second clamping assembly 3 to slide linearly, a second driving assembly 5 is further arranged to drive the second clamping assembly 3 to move along the limiting assembly 1; in the embodiment, the second driving assembly 5 specifically comprises a stepping motor 51, a shaft coupling 52, a first synchronous wheel fixing seat 53, a second synchronous wheel fixing seat 54 and a synchronous belt 55; the first synchronous wheel fixing seat 53 is fixed at the first end 111 of the slide rail 11, the second synchronous wheel fixing seat 54 is fixed at the second end 112 of the slide rail 11, a first synchronous wheel is installed inside the first synchronous wheel fixing seat 53, a second synchronous wheel is installed inside the second synchronous wheel fixing seat 54, the synchronous belt 55 extends along the first direction, and the synchronous belt 55 is wrapped around the top surface and the bottom surface of the slide rail 11 after passing through the first synchronous wheel and the second synchronous wheel, the synchronous belt is tensioned by the two synchronous wheels and can be driven to rotate by the synchronous wheels. The side of the synchronous belt 55 located on the top surface of the slide rail 11 is further fixedly connected with the first connecting block 311. The driving shaft of the stepping motor 51 is in transmission connection with one of the synchronous wheels through the shaft coupling 52, and in the embodiment, the stepping motor 51 is in transmission connection with the second synchronous wheel. When the stepping motor 51 receives a signal to rotate, it can drive the second synchronous wheel to rotate through the shaft coupling 52, and in turn drive the synchronous belt to rotate. When the synchronous belt rotates, it can drive the first connecting block 311 to move, and the first connecting block 311 can drive the connecting part 32 at the top and the tape 62 to move, thereby realizing the extension and retraction of the tape measure.

[0056] As Figure 7 shown, the top surface of the slide rail 11 is provided with a first groove 113 in the first direction; the part of the synchronous belt 55 located on the top surface of the slide rail 11 is arranged inside the first groove 113, and the first groove 113 is used to limit the synchronous belt 51 to avoid lateral deviation of the synchronous belt 55 during continuous reciprocating motion. The two sides of the slide rail 11 along the second direction are respectively provided with a second groove 114, and the second groove 114 is used to cooperate with the ball sliding block 312, and the balls of the ball sliding block 312 are embedded inside the second groove 114, so that the ball sliding block 312 can slide along the second groove 114. The two sides of the slide rail 11 along the second direction are respectively provided with a third groove 115, and the third groove 115 is used to cooperate with the fixing screw 124, and the fixing screw 124 penetrates through the groove wall 122 and then enters the inside of the third groove 115, so that the fixing block 12 and the slide rail 11 are fixed to each other.

The first waist-shaped hole 262 is used to adjust the position of the driving end of the push-pull electromagnet 265 in the height direction, and the second waist-shaped hole 264 is used to adjust the position of the driving end of the push-pull electromagnet 265 in the second direction, so that the driving end of the push-pull electromagnet 265 can be aligned with the recording button.

[0064] Further, as shown in the drawings, Figure 8As shown, on the fourth fixed plate 24, a plurality of finger units 26 are arranged, which can press the recording button 63 of the tape measure 6 from different directions.

[0065] In order to drive the first clamping assembly 2 to rotate the tape measure, a first driving assembly for driving the first clamping assembly 2 to rotate is also installed on the heightening frame 13. In the embodiment, the first driving assembly is a rudder machine 4, the main body of the rudder machine 4 is fixedly connected with the first fixed plate 141, and the driving shaft of the rudder machine 4 is in transmission connection with the second fixed plate 22. Under the transmission action of the rotating bearing 21, the power output by the driving shaft of the rudder machine 4 can drive the fourth fixed plate 24 to rotate.

[0066] In the actual test process, in order to make the length of the tape measure 6 pulled out consistent with the predetermined driving distance of the second driving assembly 5, it is necessary to keep the direction in which the tape 62 is pulled out parallel to the slide rail 11, so that the distance that the first clamping assembly 2 moves on the slide rail is equal to the distance that the tape is pulled out from the opening position. That is, during the test process, it is necessary to keep the opening of the tape body 61 at a specific height, and regardless of how the tape body rotates, it is necessary to keep the opening of the tape body 61 at a specific height. Therefore, when the tape measure 6 is installed on the fourth fixed plate 24, it is necessary to keep the opening of the tape body 61 as much as possible overlapping with the center position of the fourth fixed plate 24, so that regardless of how the tape body rotates, the height of the opening position can be maintained unchanged, and the height of the third connecting block 322 and the first clamping block 323 of the second clamping assembly 3 needs to be consistent with the height of the center of the fourth fixed plate 24, so as to ensure that the tape 62 can be pulled out horizontally.

[0067] As shown in the figure, Figure 17 In the first direction, the length of the third connecting block 322 is equal to the radius of the fourth fixed plate 24, when the second clamping assembly 3 moves to the edge position of the second end 112, the second connecting block 321 is tangent to the edge of the fourth fixed plate 24, and the edge of the third connecting block 322 is located at the center position of the fourth fixed plate 24, that is, the tap of the tape measure 6 is located at the opening position of the tape body 61. The height of the second connecting block 321 in the third direction is equal to the radius of the fourth fixed plate 24, so that after the second connecting block 321 extends upward, the height of the third connecting block 322 is located at the center position of the fourth fixed plate 24.

[0068] As shown in the figure, Figure 18 When the opening of the tape body 61 is located at the center position of the fourth fixed plate 24, when viewed in the second direction B2, the main body of the tape body 61 is located on the right side of the center, if a diameter extending in the third direction is used to divide the fourth fixed plate 24 into a first region X1 and a second region X2, then the tape body 61 and the clamp 25 are both located in the second region X2.

[0069] The control component can be a computer device capable of executing predetermined programs, such as an MCU, microcontroller, or edge computing terminal. The control component is communicatively connected to the stepper motor 51, servo motor 4, and finger unit 26, and also to the tape measure 6. The control component, communicating with the stepper motor 51, can control the stepper motor 51 to rotate according to a predetermined program, thereby moving the second clamping component along the slide rail 11 a first distance Ds. The control component, communicating with the servo motor 4, can control the servo motor 4 to rotate according to a predetermined program, thereby rotating the fourth fixing plate 24 and the ruler body 61 by a predetermined angle, thus adjusting the angle between the tape 62 and the ruler body 61. The control component, communicating with the finger unit, can control the extension or retraction of the push-pull electromagnet 265 of the finger unit 26 to simulate the pressing of the recording button 63 by a finger. The control component, communicating with the tape measure, can record the second distance Dm measured by the tape measure after the recording button 63 is pressed.

[0070] like Figure 12 to Figure 15 As shown, a first sensing component 116, a second sensing component 117, and a third sensing component 118 are also provided on the side of the slide rail 12. In the first direction, the first sensing component 116 is located at the first end 111 of the slide rail, the second sensing component 117 is located at the second end 112 of the slide rail, and the third sensing component 118 is located between the first sensing component 116 and the second sensing component 117. In this embodiment, the sensing component is specifically a photoelectric sensor. The first sensing component 116, the second sensing component 117, and the third sensing component 118 are all communicatively connected to the control component. A blocking part 33 is fixedly provided on the bottom surface of the second clamping component 3. When the blocking part 33 is inside the sensing component area, it can trigger the corresponding function according to a predetermined program. In this embodiment, the first sensing component 116 and the second sensing component 117 are limiting points. When the second clamping component 3 moves to the position of the first sensing component 116, it indicates that the second clamping component 3 has moved to the limit position close to the first end 111, and the control component issues a command to stop the stepper motor 51 from rotating. When the second clamping component 3 moves to the position of the second sensing component 117, it indicates that the second clamping component 3 has moved to the limit position close to the second end 112, and the control component issues a command to stop the stepper motor 51 from rotating. The third sensing component 118, located between the first sensing component 116 and the second sensing component 117, is used to provide positioning for the second clamping component 3. When the machine is unexpectedly stopped or started, the control component cannot distinguish the position of the second clamping component 3. When the second clamping component 3 is sensed by the third sensing component 118, it can be used as the origin position of the second clamping component 3 for the control component.
