[0035] In order to explain the technical content and structural features of the present invention in detail, the following is a further description in conjunction with the embodiments and the accompanying drawings.

[0036] See also Figure 1 and Figure 2, the present invention provides a detection device 100, which includes a turntable 101 rotatably arranged on a frame. Along the circumferential direction of the turntable 101, a feeding mechanism 10, a first detection mechanism 20, a second detection mechanism 30, and a discharging mechanism 40 are sequentially arranged along its rotation direction. Among them, a plurality of positioning mechanisms 50 for placing materials are arranged on the turntable 101 along the circumferential direction. The positioning mechanism 50 is used for placing and positioning the shrapnel. The shrapnel is placed on the positioning mechanism 50 and sequentially passes through the feeding mechanism 10, the first detection mechanism 20, the second detection mechanism 30, and the discharging mechanism 40 on the turntable 101. A pre-positioning mechanism 12 for pre-positioning the shrapnel is also arranged on the frame near the feeding mechanism 10. The pre-positioning mechanism 12 is used for pre-positioning the shrapnel. After the shrapnel is pre-positioned by the pre-positioning mechanism 12, the feeding mechanism 10 picks up the shrapnel at a specific position on the pre-positioning mechanism 12 and can place the shrapnel more accurately on the positioning mechanism 50. The specific position on the pre-positioning mechanism 12 is the position for placing the shrapnel. The feeding mechanism 10 is used to pick up the shrapnel from the pre-positioning mechanism 12 and place it on the positioning mechanism 50. The first detection mechanism 20 is used to detect the dimensions on the first surface of the shrapnel, the second detection mechanism 30 is used to detect the dimensions on the second surface of the shrapnel, and the discharging mechanism 40 is used to discharge the shrapnel after the detection is completed.

[0037] After adopting the above technical solutions, the detection device 100 of the present invention includes a pre-positioning mechanism 12 located on the frame for pre-positioning the shrapnel. Through the pre-positioning mechanism 12, the shrapnel can be accurately picked up and placed at a preset position on the positioning mechanism 50. The preset position is the position where the shrapnel is placed during detection, that is, the position where the shrapnel cooperates with the positioning mechanism 50 for detection. The positioning mechanism 50 is arranged on the rotatable turntable 101. The rotation of the turntable 101 causes the positioning mechanism 50 on the turntable 101 to sequentially pass through the feeding mechanism 10, the first detection mechanism 20, the second detection mechanism 30, and the discharging mechanism 40. The positioning mechanism 50 is used to place and position the shrapnel. The feeding mechanism 10 is used to pick up the shrapnel from the pre-positioning mechanism 12 to the positioning mechanism 50 and assist the positioning mechanism 50 to position the shrapnel. The first detection mechanism 20 is used for detecting the dimensions on the first surface of the shrapnel, the second detection mechanism 30 is used for detecting the dimensions on the second surface of the shrapnel, and the discharging mechanism 40 is used to discharge the shrapnel after the detection is completed. The detection device 100 of the present invention realizes the automatic transmission and positioning of the shrapnel, and can automatically detect the shrapnel, effectively improving the automation degree and detection efficiency, and the detection is more accurate.

[0038] Please refer to Figures 1 to 4 and Figure 7, in some alternative embodiments, the loading mechanism 10 includes a first picking structure (not shown in the figure) for picking up materials. The first picking mechanism is mounted on the frame through a support base and is close to the turntable 101. The first picking mechanism can slide between the pre-positioning mechanism 12 and the positioning mechanism 50 to pick up the elastic pieces on the pre-positioning mechanism 12 and place them on the positioning mechanism 50. Specifically, the first picking structure includes a plurality of picking components 11 and a fixing base for fixing the plurality of picking components 11. Each picking component 11 is slidably arranged on the fixing base, and the picking component 11 can slide up and down along the fixing base to pick up and place materials. The picking component 11 includes a positioning block 111 for positioning and clamping jaws 112 movably located on both sides of the positioning block 111. The clamping jaws 112 move to cooperate with the positioning block 111 to pick up and place the elastic pieces. Since the workpiece to be picked up is an elastic piece, and the elastic piece is in an eight-shaped configuration, the legs on both sides of the elastic piece will have a certain elastic movement range. Only clamping by the clamping jaws 112 will cause certain inconvenience in picking up materials. Therefore, a positioning block 111 that can extend into the elastic piece is provided in the picking component 11, and the clamping jaws 112 on both sides cooperate with the positioning block 111 in the middle to pick up the elastic piece. The positioning block 111 is provided with a protruding limiting portion. The clamping jaws 112 on both sides are opened so that the positioning block 111 can extend into the elastic piece. Limiting portions for restricting the up and down movement of the elastic piece protrude from both sides of the positioning block 111. By abutting the elastic piece with the limiting portions, and then the clamping jaws 112 on both sides of the positioning block 111 clamp the elastic piece, so that the elastic piece can be firmly picked up. The picking component 11 further includes a first cylinder 113. The clamping jaws 112 are installed at the output end of the first cylinder 113. The first cylinder 113 operates to make the clamping jaws 112 cooperate with the positioning block 111 to clamp the elastic piece.

[0039] Please refer to Figure 8 , in some alternative embodiments, the pre-positioning mechanism 12 includes a second cylinder 126 and a bottom plate 124 located at the output end of the second cylinder 126. The bottom plate 124 is slidably arranged on the frame through a first sliding assembly 125. A plurality of pre-positioning stations for pre-positioning are provided on the bottom plate 124, and a first magnetic member 121 for adsorbing the elastic pieces is provided at the pre-positioning stations. Exemplarily, the number of the first magnetic members 121 can be three to adsorb the head and two legs of the elastic piece, so that the adsorption is more firm. A limiting member 122 is also provided at the pre-positioning station. The elastic piece cooperates with the first magnetic member 121 and abuts against the limiting member 122, so that the elastic piece can be accurately pre-positioned at the pre-positioning station. A sensor 123 for detecting whether there is a workpiece is further provided on the pre-positioning mechanism 12. The sensor 123 is used to determine whether there is an elastic piece at the corresponding pre-positioning station. After the elastic piece is placed at the pre-positioning station, the second cylinder 126 operates to drive the entire bottom plate 124 to slide, so that all the elastic pieces on the bottom plate 124 abut against the corresponding limiting members 122.

[0040] Please refer toFigure 3 , Figures 5 to 7 , in some alternative embodiments, the positioning mechanism 50 includes a positioning fixture 51 located on the turntable 101 and a power assembly 52 located on the frame and cooperating with the positioning fixture 51. The power assembly 52 acts on the positioning fixture 51 or moves away from the positioning fixture 51. In this embodiment, the power assembly 52 is mounted on the frame and is located below the positioning fixture 51 in a lifting manner. The power assembly 52 includes a third cylinder 521 and a jacking assembly located at the output end of the third cylinder 521. Among them, the jacking assembly includes a first pushing member 522, a second pushing member 523, and a material pushing member 524.

[0041] Please refer to Figures 5 to 7, in some alternative embodiments, the positioning mechanism 50 includes a plurality of positioning fixtures 51. The plurality of positioning fixtures 51 are mounted on the turntable 101 through a mounting plate, and the plurality of positioning fixtures 51 on the same mounting plate are all driven by a power assembly 52. The positioning fixture 51 includes a feeding member 510 for placing the elastic piece. On both sides of the feeding member 510, a first clamping assembly 511 and a second clamping assembly 512 are oppositely arranged. A pressing assembly 514 is also arranged on the feeding member 510. Among them, the first clamping assembly 511 includes a first clamping member 5111 and a first rolling member 5112 located below the first clamping member 5111 and cooperating with the first pushing member 522. The second clamping assembly 512 includes a second clamping member 5121 and a second rolling member 5122 located below the second clamping member 5121 and cooperating with the second pushing member 523. The pressing assembly 514 includes a pressing member 5141 acting on the elastic piece and a pushing block 5142 cooperating with the power assembly 52. The first pushing member 522 and the second pushing member 523 are respectively provided with pushing inclined surfaces cooperating with the first rolling member 5112 and the second rolling member 5122. The third cylinder 521 acts so that the pushing inclined surface on the first pushing member 522 acts on the first rolling member 5112, the pushing inclined surface on the second pushing member 523 acts on the second rolling member 5122, and the pushing member 524 acts on the pushing block 5142. So that the first clamping assembly 511 and the second clamping assembly 512 on the positioning fixture 51 move away from each other, and the pressing assembly 514 lifts upward, so that the elastic piece on the feeding member 510 can be taken out. Or, the third cylinder 521 acts so that the first pushing member 522 moves away from the first rolling member 5112, the second pushing member 523 moves away from the second rolling member 5122, and the pushing member 524 moves away from the pushing block 5142. So that the first clamping assembly 511 and the second clamping assembly 512 on the positioning fixture 51 move closer to each other to clamp the elastic piece in the horizontal direction, and the pressing member 5141 moves downward to press the elastic piece, so that the movement of the elastic piece can be restricted in the horizontal left-right direction and the vertical direction, and the elastic piece can be stably placed on the feeding member 510. It can be understood that the action of a power assembly 52 can act on the first clamping assembly 511, the second clamping assembly 512 and the pressing assembly 514 on a plurality of positioning fixtures 51 at the same time.

[0042] Please refer to Figures 5 to 7, in this embodiment, the first clamping component 511 and the second clamping component 512 are symmetrically arranged on both sides of the blanking part 510. The first clamping component 511 and the second clamping component 512 are both slidably arranged on the mounting plate through slide rails. The first clamping component 511 includes a first clamping member 5111 for clamping the workpiece, and the second clamping component 512 includes a second clamping member 5121 for clamping the workpiece. A first fixing block and a second fixing block are also arranged on the mounting plate. The first fixing block is close to the first clamping member 5111 to fix the first clamping member 5111, and the second fixing block is close to the second clamping member 5121 to fix the second clamping member 5121. A first buffer member 5113 is arranged between the first fixing block and the first clamping member 5111, and a second buffer member 5123 is arranged between the second fixing block and the second clamping member 5121. The first buffer member 5113 and the second buffer member 5123 can be spring structures. With the first buffer member 5113 and the second buffer member 5123 provided, when the power component 52 moves away from the positioning fixture 51, the first buffer member 5113 and the second buffer member 5123 can drive the first clamping member 5111 and the second clamping member 5121 to slowly reset to clamp the elastic sheet after the elastic sheet is placed. On the other hand, an elastic member for driving the pressing member 5141 to reset is also arranged on the pushing block 5142. When the power component 52 moves away from the positioning fixture 51, the pressing member 5141 can also reset under the action of the elastic member to press the elastic sheet. The provision of the first buffer member 5113, the second buffer member 5123 and the elastic member can also prevent damage to the elastic sheet.

[0043] Please refer to Figures 5 to 7 , in some alternative embodiments, a first positioning component 513 linked to the first clamping component 511 and the second clamping component 512 is further arranged on the blanking part 510. When the first clamping component 511 and the second clamping component 512 clamp the elastic sheet, the first positioning component 513 penetrates through the first clamping component 511 and the second clamping component 512 to limit the movement of the elastic sheet in the first direction. When the first clamping component 511 and the second clamping component 512 move in the direction away from each other, the first positioning component 513 disengages from the elastic sheet. Specifically, the first positioning component 513 can be connected to the first clamping component 511 or the second clamping component 512 to drive the first positioning component 513 to act when the first clamping component 511 and the second clamping component 512 act. The first positioning component 513 includes a first positioning member 5131 that can cooperate with the groove on the elastic sheet and a second magnetic member 5132 for adsorbing and fixing the first positioning member 5131. The provision of the second magnetic member 5132 enables the first positioning member 5131 to cooperate more stably with the elastic sheet.

[0044] Please refer to Figures 5 to 7In some optional embodiments, the positioning jig 51 is further provided with a second positioning assembly 515 for positioning, and the second positioning assembly 515 is slidably provided on the positioning jig 51. On the other hand, the feeding mechanism 10 includes a first toggle assembly 13 for driving the second positioning assembly 515, and the first toggle assembly 13 acts on the second positioning assembly 515 to slide the second positioning assembly 515 to be located in the spring sheet. Specifically, the second positioning assembly 515 includes a second positioning member 5151, a toggle block 5152 connected to the second positioning member 5151, and a second sliding assembly 5153. The second positioning member 5151 is mounted on the mounting plate through the second sliding assembly 5153, and the toggle block 5152 protrudes above the second positioning member 5151. The first toggle assembly 13 includes a toggle block 131 that cooperates with a toggle block 5152. The power element on the first toggle assembly 13 operates to cause the toggle block 131 to act on the toggle block 5152, which in turn causes the toggle block 5152 to drive the second positioning member 5151 to slide between the two legs of the spring, thereby restricting the spring's forward and backward movement. The coordination of the first clamping assembly 511, the second clamping assembly 512, the first positioning assembly 513, the pressing assembly 514, and the second positioning assembly 515 ensures that the spring is securely placed on the discharge member 510.

[0045] See also Figure 9 In some optional embodiments, the first inspection mechanism 20 includes a first camera inspection assembly 21 and a first light source assembly 22 for inspection. The first camera inspection assembly 21 is located at the top of the turntable 101, and the first light source assembly 22 is located at the bottom of the turntable 101. The first camera inspection assembly 21 and the first light source assembly 22 cooperate to inspect the appearance and dimensions of the first surface of the spring clip on the positioning fixture 51 of the turntable 101. When the first inspection mechanism 20 inspects the spring clip, the spring clip is in a clamped state.

[0046] See also Figure 10In some optional embodiments, the second inspection mechanism 30 includes a second camera assembly 31 for inspection, a second light source assembly 32 for inspection, and a second toggle assembly 34 for actuating the positioning mechanism 50. The second camera assembly 31 is located at the bottom of the turntable 101, while the first light source assembly 22 and the second toggle assembly 34 are located at the top of the turntable 101. The second camera assembly 31 and the second light source assembly 32 cooperate to inspect the appearance and dimensions of the second surface of the spring clip on the positioning jig 51 of the turntable 101. When the second inspection mechanism 30 inspects the spring clip, it is released. The second toggle assembly 34 is used to actuate the toggle block 5152 to remove the second positioning member 5151 from the spring clip, enabling the second inspection mechanism 30 to effectively inspect the appearance and dimensions of the second surface of the spring clip. Because the second camera assembly 31 for inspection is located at the bottom of the turntable 101 with its lens facing upward, dust easily accumulates, thus affecting inspection effectiveness. Therefore, a cleaning component 33 for blowing air to clean is provided near the second camera detection component 31, so that the lens of the second camera detection component 31 can be blown to clean before the second camera detection component 31 performs detection, thereby ensuring that there is no dust on the second camera detection component 31, thereby not affecting the detection effect.

[0047] See also Figure 11 In some optional embodiments, the unloading mechanism 40 includes a dust removal structure and a second material picking structure located on the frame. The dust removal structure includes a blowing component 41 and an air suction component 42. The blowing component 41 and the air suction component 42 are arranged opposite to each other. After the shrapnel is dusted by the dust removal structure, the second material picking structure unloads the shrapnel. The structure of the second material picking structure is similar to that of the first material picking structure. Both include a plurality of material picking components 11 that can be used to clamp the shrapnel. The structure of the material picking component 11 is also similar. The blowing component 41 includes a plurality of blowing parts 411. The blowing parts 411 face the shrapnel on the positioning jig 51. The air suction component 42 is used to absorb dust on the shrapnel blown out by the blowing parts 411. After the shrapnel is cleaned by the blowing component 41 and the air suction component 42, it is unloaded by the second material picking structure.

[0048] like Figures 1 to 11As shown in the figure, the detection device 100 of the present invention includes a pre-positioning mechanism 12 located on the frame for pre-positioning the elastic sheet. Through the pre-positioning mechanism 12, the elastic sheet can be picked up and placed at a preset position on the positioning mechanism 50. The preset position is the position of the elastic sheet on the feeding member 510 during detection, that is, the position where the elastic sheet cooperates with the positioning mechanism 50 for detection. Among them, the positioning mechanism 50 is arranged on the rotatable turntable 101. The rotation of the turntable 101 enables the positioning mechanism 50 on the turntable 101 to sequentially pass through the feeding mechanism 10, the first detection mechanism 20, the second detection mechanism 30, and the discharging mechanism 40. The positioning mechanism 50 is used to place and position the elastic sheet. The feeding mechanism 10 is used to pick up the elastic sheet from the pre-positioning mechanism 12 to the positioning mechanism 50 and assist the positioning mechanism 50 in positioning the elastic sheet. The first detection mechanism 20 is used to detect the dimensions on the first surface of the elastic sheet, the second detection mechanism 30 is used to detect the dimensions on the second surface of the elastic sheet, and the discharging mechanism 40 is used to discharge the detected elastic sheet. Specifically, a positioning fixture 51 and a power component 52 cooperating with the positioning fixture 51 are arranged on the positioning mechanism 50. Through the cooperation of the positioning fixture 51 and the power component 52, the elastic sheet can be well detected on the positioning fixture 51. The detection device 100 of the present invention realizes the automatic transmission and positioning of the elastic sheet, and can automatically detect the elastic sheet, effectively improving the automation degree and detection efficiency, and the detection is more accurate.

[0049] The above-disclosed are only the preferred examples of the present invention, and the scope of the rights of the present invention cannot be limited thereby. Therefore, all equivalent changes made according to the claims of the present invention fall within the scope covered by the present invention.
