[0002] The photoelectric device includes a light-emitting component and a light-receiving component, which are arranged on the same horizontal plane. In the nut abnormality detection equipment, the photoelectric device is usually fixed on the positive electrode device first, and then the height of the detection strip is adjusted. A notch is provided at the upper end of the detection strip. When the height is adjusted accurately, the light-emitting component of the photoelectric device can pass through the notch on the detection strip and illuminate the light-receiving component.

[0003] During the detection, if the light from the photoelectric device can pass through the slot, it proves that the nut is placed correctly. When the light from the photoelectric device cannot pass through the slot, it proves that there is an abnormality in the placement of the nut, which may be due to the stacking of nuts or the inversion of nuts. When an abnormality is detected, it is fed back to the host computer.

[0004] However, during testing, the height of the equipment needs to be adjusted according to nuts of different sizes. In the prior art, the height needs to be adjusted manually, which is difficult to calibrate, inaccurate, and time-consuming. After the height is adjusted, it usually needs to be locked. In the prior art, since the staff adjusts the height by hand, one hand is needed to control the screw rod and the other hand is needed to lock it when locking. This can easily cause errors in the force applied, affecting the accuracy of the height. Utility Model Content

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", "third", "fourth", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] See also Figures 1 to 5 The embodiment of the utility model discloses a height adjustment device for a nut abnormality detection device (hereinafter referred to as "height adjustment device"), including a detection strip 1, on which a notch 2 is provided for the photoelectric device to transmit light when emitting light, and a mounting plate 3, a screw rod 4 and a threaded column 5. The mounting plate 3 is provided with a limit groove 301 for the axial movement of the detection strip 1. In addition, the mounting plate 3 is also provided with a receiving groove 302 located below the limit groove 301, and the threaded column 5 is arranged in the receiving groove 302. Furthermore, the screw rod 4 penetrates the threaded column 5 and the limit groove 301 from the bottom of the mounting plate 3 upward, and penetrates into the limit groove 301 to connect with the detection strip 1. The threaded column 5 and the screw rod 4 constitute a ball screw structure. Specifically, the surface of the screw rod 4 is provided with threads. When the threaded column 5 is fixed in the receiving groove 302, it is limited by the height of the receiving groove 302. Therefore, when the threaded column 5 is rotated by an external force, the threaded column 5 drives the screw rod 4 to move axially, and the upper end of the screw rod 4 is connected to the detection strip 1, thereby driving the detection strip 1 to move up and down in the limiting groove 301, thereby achieving the purpose of adjusting the height of the detection strip 1. In the prior art, the detection strip 1 is usually stretched manually to achieve the purpose of adjusting the height. Since the slot 2 is only 1mm wide, it is difficult to fine-tune the stretching adjustment method, and it is difficult to align the photoelectric device with the slot 1, which affects the work efficiency. The utility model changes the method of rotating the threaded column 5 to drive the screw rod 4 to move axially, thereby achieving the purpose of lifting and lowering the detection strip 1. It is not only more convenient when adjusting, but also better controlled, more accurate, and better adjustment effect.

[0039] Specifically, in the process of detecting nut abnormalities, a photoelectric device is required. The photoelectric device is an external device. The photoelectric device is provided with a light-emitting component and a light-receiving component at the same horizontal height. It is used in conjunction with the height adjustment device of the utility model to detect whether the nut is inverted or the nuts are stacked. In this embodiment, a batch of nuts of the same specification are generally tested together. Specifically, the first nut of the batch is placed first, and the height of the height adjustment device is adjusted so that the light-receiving component of the photoelectric device can receive the signal of the light-emitting component passing through the slot 2; then, the remaining nuts of the batch are tested. When the same batch of nuts is tested, the height does not need to be adjusted. When the light-emitting component of the photoelectric device can pass through the slot 2 of the detection strip 1 and is detected by the light-receiving component, it means that the height is correct, that is, the corresponding nut placement state is correct.

[0040] In this embodiment, a screw rod through hole 101 is provided at the bottom of the detection strip 1, and the screw rod 4 is inserted into the screw rod through hole 101 and fixed to the detection strip 1, so that the connection between the detection strip 1 and the screw rod 4 is more firmly established.

[0041] In this embodiment, a fixing cover 6 is further included, and the fixing cover 6 is fixed outside the limiting groove 301, so that the detection strip 1 is limited between the limiting groove 301 and the fixing cover 6. The surface of the mounting plate 3 is provided with a limiting groove 301 for the detection strip 1 to move up and down. The fixing cover 6 can ensure that the detection strip 1 does not fall off from the limiting groove 301, and the fixing effect is better.

[0042] In this embodiment, a wrench 7 is also included. The wrench 7 is provided with a fixing portion 701. The fixing portion 701 is provided with threads on its surface. The fixing portion 701 is threadedly connected to the fixing cover 6. When the wrench 7 is rotated, the fixing portion 701 presses against the detection strip to tighten the detection strip 1. After the threaded column 5 is rotated to adjust the height of the detection strip 1, in order to fix the detection strip 1 to maintain the height and prevent errors caused by accidental contact by the staff, the wrench 7 for tightening the detection strip 1 is added to fix the detection strip 1 in the limiting groove 301.

[0043] In this embodiment, the tail end of the screw rod 4 is provided with a stopper 401 that is engaged with the outside of the bottom of the mounting plate 3. Specifically, when the threaded column 5 is rotated by an external force, the threaded column 5 will drive the screw rod 4 to move axially, and the stopper 401 will always keep the tail end of the screw rod 4 outside the bottom of the mounting plate 3 to prevent the screw rod 4 from being separated from the threaded column 5 when it moves upward.

[0044] In this embodiment, the surface of the detection strip 1 is provided with a scale bar 8, and the scale bar 8 is preferably 1mm. After testing the previous batch of nuts of the same specification, when entering the next batch of nuts of the same model, the staff can visually observe the height difference between the current batch of nuts and the previous batch of nuts, and after visual estimation, turn the nut column 5 to adjust the height of the detection strip 1 upward or downward. When the light-emitting part of the photoelectric device can pass through the notch 2 to irradiate the light-receiving part, the height adjustment is completed, and the batch of nuts is inspected. When the staff is working, they first estimate the height difference of the nuts by visual observation, and then adjust the height through the scale bar 8, which is faster and more accurate.

[0045] In this embodiment, a fixed bracket 9 is also included, and a horizontal moving groove 10 is provided in the fixed bracket 9; a raised moving block 303 is provided at the rear end of the mounting plate 3, and the moving block 303 is embedded in one side of the moving groove 10, and a fixed block 11 is provided on the other side of the moving groove 10 and passes through the moving groove 10 to connect with the moving block 303, and the mounting plate 3 can move horizontally along the moving groove 10. In the nut abnormality detection equipment, the photoelectric device is usually fixed on the frame, and the height adjustment device is fixed on the pressure mechanism. Specifically, the fixed bracket 9 is fixed on the pressure mechanism. In order to ensure that the light-emitting part of the photoelectric device can irradiate the light-receiving part through the notch, in addition to the height adjustment, the light-emitting part and the light-receiving part of the photoelectric device need to be brought into the range of the notch 2 in the horizontal direction. By adding the function of adjusting the mounting plate 3 forward and backward by the moving groove 10, the photoelectric device can better calibrate the notch 2.

[0046] In this embodiment, the photoelectric device is fixed on the frame, and the height adjustment device is fixed on the pressure mechanism, wherein the photoelectric device should be in the same straight line with the height adjustment device in the vertical direction, a positive electrode device is provided on the frame, and a negative electrode device is provided on the pressure mechanism. When testing nuts, nuts of uniform specifications are tested as a batch, the first nut of the batch is taken out, the nut is placed on the negative electrode device, and the positive electrode device is moved downward until it stops when it touches the nut, after which the staff starts to adjust the height adjustment device.

[0047] Specifically, the height adjustment device includes a detection strip 1, a mounting plate 3, a screw rod 4, a threaded column 5 and a fixed bracket 9; in the process of adjusting the height adjustment device, the vertical height and the front-to-back distance are adjusted so that the slot 2 is aligned with the photoelectric device. Specifically, the vertical height mainly includes that the mounting plate 3 includes a limit groove 301 and a receiving groove 302, the detection strip 1 is arranged in the limit groove 301, and a fixed cover 6 is fixed outside the limit groove 301 so that the detection strip 1 is limited between the limit groove 301 and the fixed cover 6, the screw rod 4 and the threaded column 5 constitute a ball screw structure, and the screw rod 4 is connected to the bottom of the detection strip 1. When the staff rotates the threaded column 5, the screw rod is rotated by the threaded column 5 and moves axially, thereby driving the detection strip 1 to move up and down. This is one of the steps to adjust the height adjustment device so that the slot 2 is aligned with the photoelectric device. After rotating the threaded column 5 to adjust the height, it is sometimes necessary to move the detection strip 1 forward or backward so that the photoelectric device can pass through the slot. When adjusting the front and rear distance, it mainly involves the fixed bracket 9, which is provided with a movable slot 10; specifically, the movable block 303 at the tail end of the mounting plate 3 is embedded in the movable slot 10, and a fixed block 11 is provided at the other end of the movable slot 10. The fixed block 11 is passed through the movable slot 10 and fixed to the movable block 303, so that the mounting plate 3 can move horizontally along the movable slot 10 to achieve the effect of moving the height adjustment device forward and backward. After the moving groove 10 and the threaded column 5 are set so that the light-emitting part and the light-receiving part of the photoelectric device can be aligned with the slot 2, the height adjustment of the batch is completed, the positive electrode device is moved upward, the nut is removed, and the next nut of the batch is replaced. The positive electrode device is then moved downward until it touches the nut, and the photoelectric device is started. If the light-receiving part of the photoelectric device can receive the signal emitted by the light-emitting part from the slot 2, it means that the nut is normal, and the next nut is replaced for inspection. When the light-receiving part of the photoelectric device cannot detect the signal of the light-emitting part, it means that the photoelectric signal cannot pass through the slot 2, which proves that there is a problem with the height of the nut, which may be due to the stacking of nuts or the inversion of nuts. When an abnormality is detected, it is fed back to the host computer.

[0048] When adjusting the height of the height adjustment device, compared with the hand-pull adjustment in the traditional technology, the utility model adopts the combination of the nut column 5 and the screw rod 4. The staff only needs to rotate the nut column 5 to make the screw rod 4 rise and fall to achieve the purpose of moving the detection strip 1 up and down. This method is more stable. When adjusting, compared with the hand-pull adjustment method, the adjustment device is more accurate and convenient for fine-tuning; and the utility model is also equipped with a wrench 7, which is rotated to tighten the detection strip 1 to prevent other staff from accidentally touching it; in the prior art, due to the hand-pull height adjustment method, when the wrench 7 is rotated to fix it, the other hand needs to control the height of the current detection strip 1, while the utility model has fixed the height in the process of rotating the threaded column 5, and rotating the wrench 7 is a safer and anti-accidental touch method of tightening the detection strip 1, so when rotating the wrench 7, there is no need to control the current height with the other hand; and when replacing the next batch of nuts, the height difference between the two batches of nuts can be visually observed first, and then the scale bar 8 on the detection strip 1 can be adjusted to the corresponding height more quickly, which is more convenient and accurate.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
