[0029] As Figure 1-2 shown, in an embodiment of a detection device, the detection device includes a bracket 1 and a driving mechanism 2. Along a first direction, a first mounting position 111 and a second mounting position 112 are spaced on the bracket 1. Both the first mounting position 111 and the second mounting position 112 are used to mount one end of a spring 100. The driving mechanism 2 includes a driving component 21, a transmission component 22 and an optocoupler 23. The transmission component 22 is located between the first mounting position 111 and the second mounting position 112 and can be connected to the spring 100 connected to the first mounting position 111 and the second mounting position 112. The driving end of the driving component 21 is connected to the transmission component 22 and is used to drive the transmission component 22 to reciprocate between the first mounting position 111 and the second mounting position 112. The optocoupler 23 is mounted on the bracket 1 and is located between the first mounting position 111 and the second mounting position 112. The optocoupler 23 is used to detect the transmission component 22.

[0030] In this embodiment, by providing the first mounting position 111 and the second mounting position 112 in the first direction on the bracket 1 and providing the transmission component 22 in the middle of the first mounting position 111 and the second mounting position 112, in this way, under the drive of the driving component 21, the reciprocating movement of the transmission component 22 between the first mounting position 111 and the second mounting position 112 can compress the spring 100 at the first mounting position 111 while stretching the spring 100 at the second mounting position 112, or vice versa, improving the detection efficiency. And by providing the optocoupler 23, the test times of the spring 100 can be known according to the trigger times of the optocoupler 23.

[0031] The first direction can be Figure 1 the X direction in

[0032] Specifically, the bracket 1 may include a bottom plate 12 and a vertical plate 11. The vertical plate 11 is vertically installed on the bottom plate 12. In terms of placement, the base is placed horizontally, so that the vertical plate 11 can be vertical along the direction of gravity. In this way, components such as the driving mechanism 2 and the spring 100 installed on the vertical plate 11 can save space. It can be understood that the spring 100 is suspended on the first installation position 111 and the second installation position 112. For this reason, the first installation position 111 and the second installation position 112 can be of various structural shapes, such as protrusions, grooves or hole-like structures, which can be used for the spring 100 to be snap-connected. Further, in order to improve the connection stability between the spring 100 and the bracket 1, the spring 100 can also be fixed by bolts in cooperation with grooves and hole-like structures.

[0033] It can be understood that the driving mechanism 2 can be in various forms such as a cylinder or a linear motor, as long as it can achieve reciprocating motion. The transmission component 22 can be a plate-like or block-like structural member.

[0034] In an embodiment of the detection device, the transmission component 22 includes a main body 221 and a shielding member 222. The driving end of the driving component 21 is connected to the main body 221, and the shielding member 222 is connected to the main body 221 and is used to shield the optical signal of the optocoupler 23.

[0035] In this embodiment, specifically, the main body 221 can be a plate-like structural member, and the shielding member 222 can protrude from the main body 221, such as a plate-like or sheet-like structural member. By setting the shielding member 222, the optocoupler 23 can be better shielded, avoiding accidental triggering of the optocoupler 23 and improving the accuracy. Specifically, the optocoupler 23 has a transmitting end and a receiving end. Under normal conditions, the receiving end can receive signals from the transmitting end. The shielding member 222 can pass through the transmitting end and the receiving end during reciprocating movement, thereby blocking the receiving end from receiving signals, so that the number of test times can be known.

[0036] In an embodiment of the detection device, a first fixing portion 2211 and a second fixing portion 2212 are respectively provided on the main body 221 at intervals along a first direction. The first fixing portion 2211 can be connected to the spring 100 installed on the first installation position 111, and the second fixing portion 2212 can be connected to the spring 100 installed on the second installation position 112.

[0037] In this embodiment, by providing the first fixing portion 2211 and the second fixing portion 2212, it is convenient to connect and fix with the spring 100.

[0038] Specifically, the first fixing portion 2211 is a protrusion, a groove or a hole, and / or the second fixing portion 2212 is a protrusion, a groove or a hole.

[0039] In this embodiment, when it is a protrusion, the spring 100 can be hooked on the protrusion. Preferably, a groove or hole can be formed on the side wall of the protrusion to hook the spring 100. When it is a groove or hole, the spring 100 can be hooked on the inner wall of the groove or hole.

[0040] In an embodiment of a detection device, the first fixing portion 2211 is a groove or a hole, and a thread is provided in the groove or the hole. The transmission assembly 22 further includes a fastener that can cooperate with the thread to fix the spring 100. And / or, the second fixing portion 2212 is a groove or a hole, and a thread is provided in the groove or the hole. The transmission assembly 22 further includes a fastener that can cooperate with the thread to fix the spring 100.

[0041] In this embodiment, as shown in the spring 100 in the figure, for such a spring 100 having holes formed at both ends, bolts can pass through it to connect with the threads on the first fixing portion 2211 or the second fixing portion 2212, enabling the spring 100 to be stably fixed.

[0042] In an embodiment of a detection device, there are multiple first mounting positions 111, and the first mounting positions 111 are arranged at intervals along a second direction, and the second direction is arranged at an angle with the first direction. And / or, there are multiple second mounting positions 112, and the second mounting positions 112 are arranged at intervals along the second direction, and the second direction is arranged at an angle with the first direction.

[0043] In this embodiment, by arranging multiple first mounting positions 111 and / or multiple second mounting positions 112 along the second direction, the number of springs 100 can be increased, thereby further improving the detection efficiency.

[0044] Combined with the previous embodiments and the figure, the first direction can be the vertical direction, and the second direction can be the horizontal direction.

[0045] In an embodiment of a detection device, the driving assembly 21 includes a driving member 211, a first wheel 212, a second wheel 213, and a transmission belt 214. The driving member 211, the first wheel 212, and the second wheel 213 are all mounted on the bracket 1. The first wheel 212 and the second wheel 213 are arranged at intervals along the first direction. The transmission belt 214 is sleeved on the first wheel 212 and the second wheel 213 and is fixedly connected to the transmission assembly 22. The driving end of the driving member 211 is connected to the first wheel 212 or the second wheel 213. The driving member 211 is used to drive the first wheel 212, the transmission belt 214, and the second wheel 213 to rotate, so as to drive the transmission assembly 22 to reciprocate between the first mounting position 111 and the second mounting position 112 through the transmission belt 214.

[0046] This embodiment provides a specific structural composition of a driving component 21. Specifically, the driving member 211 can be a motor, which is used to drive the first wheel 212, the second wheel 213, and the transmission belt 214 to rotate, thereby driving the transmission component 22 (main body 221) connected to the transmission belt 214 to move reciprocally. By adopting the method of combining the motor with the transmission belt 214, it is convenient to control.

[0047] In an embodiment of a detection device, the driving end of the driving member 211 is connected to the second wheel 213. A through hole is provided in the bracket 1 corresponding to the position of the second wheel 213, and the driving member 211 passes through the through hole.

[0048] In this embodiment, combined with the previous embodiment, as shown in the figure, the first wheel 212 and the second wheel 213 are arranged in sequence along the first direction, and the first direction is the vertical direction. Thus, it can be understood that the second wheel 213 is arranged at the bottom. Further, the driving member 211 is arranged at the bottom. By arranging the driving member 211 at the bottom, the center of gravity of the overall device can be reduced, and the stability of the device can be improved.

[0049] In an embodiment of a detection device, the driving component 21 further includes a guide rail 24 and a slider 25. The guide rail 24 is installed on the bracket 1, and the extending direction of the guide rail 24 is parallel to the first direction. The slider 25 is slidably connected to the guide rail 24 and is connected to the transmission component 22.

[0050] In this embodiment, by providing the guide rail 24 and the slider 25, the effect of guiding the movement of the transmission component 22 can be achieved, and the movement accuracy can be improved.

[0051] In an embodiment of a detection device, the annular extending direction formed by the surrounding of the transmission belt 214 is parallel to the first direction. In this embodiment, by setting the annular extending direction formed by the surrounding of the transmission belt 214 to be parallel to the first direction, the effects of energy saving and high efficiency can be achieved. It can be understood that the transmission belt 214 is surrounded to form a ring, and its extending direction needs to be considered from the overall shape and is axisymmetric along the first direction.

[0052] The technical features of the above embodiments can be combined arbitrarily. For the sake of brief description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
