DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more explicit definition of the protection scope of the present invention. Obviously, the embodiments described in the present invention are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] Embodiment 1: The specific structure of the present invention is as follows: Please refer to the attached Figure 1-9 An automatic detection device for a rod component of the present invention includes a frame 1 having a platform. The detection device also includes a turntable mechanism 4, a plurality of supporting fixtures 41, an automatic feeding device 3, an opening and closing device 8, a beam detection device 7 and a positioning mechanism 9.

[0034] The turntable mechanism 4 has a turntable 42 rotatably mounted on the platform and a first power source mounted on the platform and drivingly connected to the turntable 42 to enable the turntable to rotate in a horizontal circle. The turntable 42 is rotatably mounted on the platform via a supporting cylinder, and the first power source is an intermittent divider, which drives the turntable 42 to rotate intermittently. A plurality of support fixtures 41 are distributed in a ring array on the edge of the turntable surface, and each support fixture 41 has a support slot 411; the support slot 411 is a first V-shaped structural groove with an opening facing upward, such as Figure 2 The rod member 6 can fall into the first V-shaped structural groove, and the outer edge of the turntable 42 is distributed with first notch grooves in an array, and each first notch groove is arranged one-to-one with each supporting fixture 41.

[0035] like Figure 4 As shown, the support fixture 41 includes a bottom plate and a vertical block, the outer end of the bottom plate is provided with a second notch groove, and the first notch groove and the second notch groove overlap and align. The vertical block is vertically arranged at the edge of the bottom plate, and a through hole 412 is arranged in the upper and lower directions of the middle part thereof, and a vertically communicating channel is formed between the through hole 412, the first notch groove, and the second notch groove, and the first V-shaped structural groove is arranged at the upper end of the vertical block and the horizontal direction of the first V-shaped structural groove passes through the through hole 412.

[0036] The automatic feeding device 3 is fixed to the platform and is located at the feeding station of the platform; the automatic feeding device 3 includes a straight vibrator 31 and a straight vibration plate 32 arranged at the upper end of the straight vibrator 31, the straight vibration plate 32 has a linear groove 33, and the discharge end of the linear groove 33 points to the receiving slot 81. The feed of the straight vibration plate 32 is provided by a vibration disk, and the rod body member 6 vibrated by the vibration disk is guided to the linear groove 33 through a guide groove, and the linear groove 33 is a second V-shaped structural groove. When the straight vibrator 31 vibrates, it will drive the straight vibration plate 32 to vibrate. After the straight vibration plate 32 vibrates, it will generate a thrust in the direction of the discharge port of the straight vibration plate 32, thereby driving the rod body member 6 in the linear groove 33 in the direction of the discharge port.

[0037] The openable and closable device 8 is fixed to the platform. The openable and closable device 8 has an openable and closable component and a second power source for driving the closable component to open and close. The second electric power source is a first clamping cylinder, and the first clamping cylinder drives and connects the openable and closable component. The openable and closable component has an openable and closable receiving slot 81. The receiving slot 81 is located above the rotation path of the supporting slot 411. When the supporting slot 411 reaches directly below the receiving slot 81, there is a vertical penetration space between the supporting slot 411 and the receiving slot 81. The channel formed between the through hole 412, the first notch slot, and the second notch slot is within the penetration space area. After the opposing beam detection device 7 is fixed to the platform, the vertical opposing direction between them is within the range of the penetration space. The opposing beam detection device 7 includes a one of an opposing beam photoelectric sensor and an opposing beam laser sensor. The opening and closing assembly includes two opening and closing brackets, and the two opening and closing brackets are provided with relative inclined surfaces, and the two inclined surfaces form the receiving slot 81 with an upward opening and a V-shaped structure. When there is no obstacle between the opposing detection device 7, the two opening and closing brackets are in a closed state, and a certain gap is left between them for light to pass through. The width of the gap is sufficient to prevent the rod member 6 on the receiving slot 81 from falling. The receiving slot 81 is aligned with the linear slot 33 in a straight line. When the rod member 6 in the linear slot 33 enters the receiving slot 81, the rod member 6 blocks the light, and the light between the opposing detection devices 7 is isolated, which sends a signal to the processing center, and the processing center controls the two opening and closing brackets to open, so that the rod member 6 falls into the supporting slot 411, and the turntable mechanism 4 rotates an angle, so that the supporting fixture 41 that receives the rod member 6 enters the positioning station.

[0038] like Figure 8As shown, the positioning mechanism 9 is arranged on the platform and is located at the positioning station of the platform. It has a positioning assembly and a third power source for driving the positioning assembly to open and close. The clamping area between the positioning assemblies is on the rotation path of the support slot 411. The positioning assembly includes two positioning blocks 91 that can be opened and closed. There is a clamping opening between the two positioning blocks 91 that can be opened and closed. There is a clamping area between the clamping openings. When the support slot 411 reaches the clamping area and stops moving, the support slot 411 is perpendicular to the two opposite sides of the clamping area. A clamping opening is provided in the lower area of ​​the gap between the two positioning blocks 91, and the clamping opening can meet the passage of the vertical block on the support fixture 41.

[0039] The third power source is the second clamping cylinder, which drives and connects two openable and closable positioning blocks 91. The two openable and closable positioning blocks 91 are driven to an open state. When the supporting slot 411 reaches the clamping area and stops moving, the second clamping cylinder drives the two openable and closable positioning blocks 91 to clamp. After the clamping mouths of the two openable and closable positioning blocks 91 clamp the rod body component 6, they are released. At this time, the rod body component 6 is in the preset position of the supporting slot 411. The preset position makes the detection of the rod body component 6 more accurate.

[0040] The automated inspection equipment further includes at least one set of CCD camera inspection devices 5, which are arranged on the platform and located at the inspection station between the positioning station and the unloading station, and the lens of the CCD camera inspection device 5 is directed to the support slot 411 directly below the lens. There are multiple CCD camera inspection devices 5, and the lens of the CCD camera is directed to the support slot 411 after reaching it, and takes pictures and sends them to the processing center, which compares the preset parameters, determines whether the rod member 6 is qualified, and makes calibration.

[0041] like Figure 3 , 9 As shown, Fig. 9 This is a structural diagram of the unloading mechanism of the present invention. The automated detection equipment also includes at least one unloading mechanism 2. The unloading mechanism 2 includes a fourth power source and a push rod bracket 10 driven and connected to the fourth power source. The push rod bracket 10 is height-adjustably mounted with a push rod 101.

[0042] Figure 3 In the embodiment, six groups of unloading mechanisms 2 are arranged on the platform, and the six groups of unloading mechanisms correspond to six fixture stations, and 1-2 groups are set as unqualified stations. When an unqualified rod body component 6 reaches the unqualified station, the unloading mechanism 2 at the unqualified station drives the push rod bracket 10 to retreat, and the push rod 101 pushes the unqualified rod body component 6 out of the supporting slot 411. When a qualified product reaches a qualified station, the current unloading mechanism 2 drives the push rod bracket 10 to retreat, and the push rod 101 pushes the qualified rod body component 6 out of the supporting slot 411.

[0043] The above action cycle allows the rod member 6 to be detected continuously, thereby improving the detection efficiency.

[0044] In summary, the present invention eliminates the traditional feeding robot and uses a direct vibrator to vibrate the material, thereby improving the feeding efficiency through vibration feeding. The automatic feeding device is low in cost compared to the existing robot structure. The present invention is provided with a through-type detection device to detect whether the rod body component is delivered to the receiving slot, and a penetrating space is provided to ensure that the rod body component can block the through-light. The present invention uses the structure of a turntable to efficiently detect the rod body component, and the detection efficiency is high. The present invention is also provided with a positioning mechanism to keep the rod body component in a fixed position on the fixture to meet the detection requirements of the CCD camera detection device.
