[0033] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0034] like Figure 1 The figure shows the structure of the product after press-fitting. The product consists of a pressing sheet and a lifting ear which are press-fitted to each other. The lifting ear is provided with a penetrating pressing hole. A convex column is integrally connected to the pressing sheet. The convex column is press-fitted into the pressing hole by a press machine, thereby completing the assembly of the product.

[0035] like Figure 2 The figure is a schematic diagram of the structure of the automatic detection device for blanking of products after press-fitting of the utility model, which is used for Figure 1 The device is shown in the figure. The product after press-fitting is inspected to detect whether the lifting lug is press-fitted in place. The device comprises a support component 1, a detection component 2, a transfer component 3 and a blanking component 4. The support component 1 is used to support the product to be inspected and the remaining components. The detection component 2 is used to inspect the product after press-fitting to detect whether the lifting lug is press-fitted in place. The transfer component 3 is used to clamp the inspected product. The blanking component 4 is divided into a first collecting mechanism and a second collecting mechanism. The first collecting mechanism is used to collect qualified products clamped by the transfer component 3, and the second collecting mechanism is used to collect unqualified products clamped by the transfer component 3.

[0036] The support assembly 1 includes a support frame 101, a rotating motor 102, a rotating plate 103 and a bearing platform 104. The support frame 101 is fixed on the assembly line machine by screw fastening, and the rotating motor 102 is fixed on the top of the support frame 101 to drive the rotating plate 103 to rotate. The bearing platform 104 is fixed on the top of the rotating plate 103, and is used to carry the pressed product, and driven by the rotating plate 103, it rotates to the detection assembly 2 for detection, and then rotates to the transfer assembly 3 to clamp the blank.

[0037] like Figure 3 , 4As shown, it is a schematic diagram of the structure of the detection component 2. The detection component 2 is used to detect the product after press-fitting, so as to ensure whether the lifting lug is pressed in place. The detection component 2 includes a detection frame 201, a vertical displacement platform 202, a lifting plate 203, a detection cylinder 204, a connecting plate 205, an angle plate 206, a proximity switch 207, a sleeve plate 208, a linear bearing 209, a guide column 210, a detection plate 211, a avoidance groove 212, a detection column 213, a reset spring 214 and an anti-slip block 215. The detection frame 201 is vertically fixed on the top of the support frame 101, the vertical displacement platform 202 is fixed on the side of the detection frame 201 close to the rotating plate 103, and the lifting plate 203 is connected to the vertical displacement platform 202, and the lifting plate 203 is driven to rise and fall in a vertical plane through the vertical displacement platform 202. The vertical displacement platform 202 can be a commercially available "WN215TM120L" model displacement platform.

[0038] The detection cylinder 204 is fixed on the side of the lifting plate 203 close to the rotating plate 103, and the connecting plate 205 is fixed on the bottom of the detection cylinder 204. The connecting plate 205 is driven to move up and down by the detection cylinder 204. The lifting plate 203 is driven to move up and down by the vertical displacement platform 202, so as to adjust the initial height of the detection cylinder 204 to meet the detection work of products of different sizes.

[0039] The angle plate 206 is fixed to one side of the connecting plate 205, and performs synchronous lifting and lowering motion with the connecting plate 205. The angle plate 206 is in an "L" shape, the proximity switch 207 is fixed to the top of the "L"-shaped angle plate 206, the sleeve plate 208 is fixed to one side of the bottom of the "L"-shaped angle plate 206, and the proximity switch 207 is located above the sleeve plate 208.

[0040] The linear bearing 209 is embedded in the sleeve plate 208, the guide column 210 is inserted in the linear bearing 209, and the bottom of the guide column 210 is fixed with a detection plate 211. By providing the guide column 210 and the linear bearing 209 that cooperate with each other, the descending sleeve plate 208 is guided to improve the accuracy of the detection result.

[0041] The detection column 213 is fixed on the top of the detection plate 211 and penetrates the cover plate 208. The detection column 213 cooperates with the upper proximity switch 207. The anti-dropping block 215 is fixed on the top of the detection column 213, and the diameter of the anti-dropping block 215 is larger than the diameter of the detection column 213. Under the resistance of the anti-dropping block 215, the detection column 213 and the detection plate 211 are prevented from falling from the cover plate 208.

[0042] The reset spring 214 is sleeved on the detection column 213 and respectively abuts against the sleeve plate 208 and the detection plate 211. After the detection is completed, the detection column 213 is reset by the reset spring 214 to facilitate the subsequent product detection; and under the elastic force of the reset spring 214, it can be ensured that the detection column 213 does not tilt during the rising and falling process, thereby improving the accuracy of the detection result.

[0043] The detection steps of detection component 2 are as follows:

[0044] First, adjust the vertical displacement table 202 according to the size of the product to be tested, until the detection cylinder 204 is at a suitable height, and set the descending distance of the detection cylinder 204. The detection cylinder 204 drives the sleeve plate 208 to descend until the detection plate 211 contacts the lower ear, and the detection cylinder 204 continues to descend until the detection column 213 rises and abuts against the proximity switch 207. Only when the descending distance of the detection cylinder 204 meets the set distance and the detection column 213 and the proximity switch 207 just abut, can the product be pressed into place; if the detection column 213 abuts against the proximity switch 207, but the descending distance of the detection cylinder 204 does not reach the set stroke, it means that the ear is not pressed into place; if the descending distance of the detection cylinder 204 meets the set distance, but the detection column 213 and the proximity switch 207 do not abut, it means that the ear is pressed too. After the detection is completed, when the detection cylinder 204 is reset, the reset spring 214 drives the detection column 213 to reset.

[0045] A side of the detection plate 211 is provided with an avoidance groove 212, which is used to avoid the position of the convex column of the product. By setting the detection plate 211, the contact area with the lower ear can be increased during detection, thereby improving the accuracy of the detection result. If the installation of the ear is detected only by the detection column 213, due to the limited contact area, a detection blind area will appear, resulting in a detection loophole.

[0046] like Figure 5 , 6 As shown, it is a schematic diagram of the structure of the transfer assembly 3. The transfer assembly 3 is used to clamp the tested product and place it on the blanking assembly 4 below. The transfer assembly 3 includes a transfer frame 301, a slider 302, a slide rail 303, a push cylinder 304, a transfer plate 305, a rotating cylinder 306, a horizontal displacement table 307, a moving plate 308, a clamping cylinder 309, a clamping plate 310 and an anti-slip protrusion 311. The transfer frame 301 is fixed to the top of the support frame 101, the slider 302 is fixed to the top of the transfer frame 301, and the slide rail 303 is slidably mounted on the slider 302. The transfer plate 305 is fixed to the slide rail 303 and moves under the drive of the push cylinder 304 to approach or move away from the rotating plate 103, so as to facilitate the clamping of the tested product on the carrier 104.

[0047] The rotating cylinder 306 is fixed on the top of the transfer plate 305, and the horizontal displacement stage 307 is fixed on the rotating part of the rotating cylinder 306. The horizontal displacement stage 307 can be a commercially available "WN215TM120L" displacement stage. By setting the rotating cylinder 306, the product clamped by the clamping cylinder 309 is placed on the first collection mechanism or the second collection mechanism.

[0048] The moving plate 308 is fixed on the top of the horizontal displacement table 307, and the clamping cylinder 309 is fixed on the top of the moving plate 308 to clamp the tested product on the carrier 104. By setting the moving plate 308, the position of the clamping cylinder 309 is properly adjusted to ensure that the clamping cylinder 309 can accurately clamp the product on the carrier 104.

[0049] The clamping plate 310 is fixed on the clamping cylinder 309, and the anti-skid protrusion 311 is integrally arranged on the inner side of the clamping plate 310. The clamping cylinder 309 drives the clamping plate 310 to move inward to clamp the product on the carrier 104. The anti-skid protrusion 311 can increase the contact area with the product and prevent the product from falling during transfer.

[0050] The blanking assembly 4 is arranged below the transfer assembly 3, and is used to carry and collect the tested products. The blanking assembly 4 is divided into a first collecting mechanism and a second collecting mechanism. The first collecting mechanism is used to collect qualified products (i.e., products that are pressed into place). The second collecting mechanism is used to collect unqualified products (i.e., products that are not pressed into place).

[0051] like Figure 7 , 8 , which is a schematic diagram of the structure of the first collecting mechanism, and the first collecting mechanism includes a blanking rack 403, a driving cylinder 404, a driven cylinder 405, a conveyor belt 406, a blanking motor 407, a driving wheel 408, a driven wheel 409, an adjustment slot 410, an adjustment roller 411, a guide column 412, a support plate 413 and a driving belt 414. The blanking rack 403 is fixed on the top of the support frame 101, the driving cylinder 404 is rotatably mounted on one side of the blanking rack 403, the driven cylinder 405 is adjustably mounted on the other side of the blanking rack 403, and the conveyor belt 406 is wound around the driving cylinder 404 and the driven cylinder 405 to complete the conveying of qualified products. The conveyor belt 406 is made of rubber, and when conveying qualified products, scratches on the surface of the products are avoided.

[0052] like Figure 8 As shown, the adjusting groove 410 is opened on the side of the blanking rack 403 away from the active cylinder 404, and the adjusting roller 411 is adjustably arranged in the adjusting groove 410. A movable cylinder connected to the adjusting roller 411 is fixed on the outer side of the blanking rack 403 to push the adjusting roller 411, thereby satisfying the tension of the conveyor belt 406 (the movable cylinder is not shown in the figure).

[0053] The guide column 412 is fixed in the adjustment slot 410 and passes through the adjustment roller 411. The adjustment roller 411 is guided by the guide column 412 when moving to prevent the adjustment roller 411 from tilting. The driven cylinder 405 is mounted on the adjustment roller 411 through a bearing sleeve to ensure the normal rotation of the driven cylinder 405.

[0054] The support plate 413 is fixed in the blanking rack 403 to support the conveyor belt 406 to prevent the conveyor belt 406 from sinking inwards and affecting the normal conveyance of the product.

[0055] The blanking motor 407 is fixed at the bottom of the blanking rack 403, and the output end of the blanking motor 407 is connected to the driving wheel 408, the driven wheel 409 is connected to one end of the driving cylinder 404, and the driving belt 414 is wound around the driving wheel 408 and the driven wheel 409. The blanking motor 407 drives the driving cylinder 404 to rotate, thereby driving the conveyor belt 406 to rotate.

[0056] The diameter of the driving wheel 408 is greater than the diameter of the driven wheel 409 , and the stacking of products on the conveyor belt 406 is avoided by increasing the rotation speed of the driven wheel 409 .

[0057] The second collecting mechanism includes a collecting box 401 and a blanking plate 402 obliquely arranged above the collecting box 401, and is used to collect unqualified products.

[0058] The automatic detection and blanking device for products after press-fitting of the utility model completes the automatic detection of products through the detection component 2, and then the transfer component 3 transfers the products to the first collection mechanism and the second collection mechanism. The whole process has a high degree of automation, which significantly improves the detection efficiency of products and the accuracy of detection results, and will not cause the problem of false detection and missed detection, and does not require manual input, saving costs.
