Description

Technical Field

[0001] The utility model belongs to the technical field of printed tin products, and particularly relates to a detection device for printed tin products. Background Art

[0002] Printed tin can making is a process of printing patterns on tinplate and then making the material into various shaped packaging products. In the printed tin step, it mainly involves printing various patterns on tinplate, which is an important basic link in the whole production process. Tinplate, as a metal material, has good ductility and hardness and is suitable for printing various patterns. In the can making stage, the printed tinplate will be further processed into various shapes required by customers, such as round, square or special-shaped cans. This process needs to ensure the beauty and practicability of the products, and at the same time, it is also a test of the quality of the printed patterns. After the printed tin cans are made, spot checks need to be carried out on the cans, and the lid grooves and the cans are detected.

[0003] However, there are still some deficiencies in the existing detection devices. For example, when detecting the lid grooves of printed tin cans, the cans need to be rotated for detection. Since the lid grooves are prone to deformation during the production process, the error tolerance of rotating the cans to check the lid grooves is relatively high, and the depth of the lid grooves and the thickness of the lid groove edges cannot be accurately detected. Moreover, the problem of lid groove deformation cannot be accurately detected, resulting in omissions in the spot checks of defective products. And because the existing detection devices do not have a comprehensive detection of the can body shell, when the can body shell has unevenness during the production process, the detection accuracy of the flatness of the can body shell by the detection device is relatively low, thus affecting the efficiency of spot checks of the cans after production.

[0040] Referring to the attachedFigure 4 , Figure 5 , the top of the robotic arm mechanism 2 is connected to a cover groove detection mechanism 3. The cover groove detection mechanism 3 includes a box body 31, a rotating rod 32 arranged on the lower side of the box body 31, and a circular limiting piece 33 arranged at the bottom of the rotating rod 32. A cylindrical hole is opened on one side of the box body 31, and a rectangular groove communicating with the cylindrical hole is opened on one side of the box body 31. The box body 31 is movably connected to the rotating rod 32 through the cylindrical hole. At the same time, a first driving motor 241 is arranged at one end of the third clamping arm 24, and the first driving motor 241 is provided with a rectangular groove matching the rectangular groove of the box body 31. At the same time, a rotating shaft 242 is fixedly arranged in the rectangular groove. Then, an annular groove is opened on the outer side of the rotating shaft 242, and a transmission belt 243 is movably connected in the annular groove. Thus, the rotating shaft 242 is connected to the rotating rod 32 through the transmission belt 243. By using the rectangular groove opened on the inner side of the box body 31, the rotating shaft 242 and the transmission belt 243 are accommodated therein. At the same time, the rotating rod 32 is arranged in the cylindrical hole, and an annular groove matching the rotating shaft 242 is opened on the outer side of the rotating rod 32. Through the rotating shaft 242 and the transmission belt 243 arranged inside the first driving motor 241 and inside the box body 31, the first driving motor 241 drives the rotating rod 32 to perform regular reciprocating motion, controlling the arc-shaped limiting block 322 to detect the depth of the cover groove of the tank body and the uniformity of the thickness of the edge of the cover groove, so as to ensure the flatness of the outer shell of the tank body after can making.

At the same time, a circular limiting piece 33 is fixedly connected to the lower side of the rotating rod 32 through the connecting rod 321. Then, a connecting groove 331 is opened in the middle of the circular limiting piece 33, and three limiting holes 332 are opened on the same side of the connecting groove 331. At the same time, an arc-shaped limiting groove 323 is opened at the bottom of the arc-shaped limiting block 322. Then, the arc-shaped limiting block 322 is movably clamped with the circular limiting piece 33 through the limiting holes 332, so as to facilitate the regular reciprocating rotation of the arc-shaped limiting block 322 in the limiting holes 332. The arc-shaped limiting groove 323 matches the depth of the cover groove of the tank body and the edge of the cover groove. Thus, by rotating on the top of the tank body with the arc-shaped limiting groove 323, the depth of the cover groove of the tank body and the uniformity of the thickness of the edge of the cover groove are detected. If the cover groove is deformed or the thickness is abnormal when the tank body is formed, the cover groove detection mechanism 3 will stop urgently and alarm, so as to eliminate the defective products of the tank body after can making.

At the same time, a cylinder is fixedly connected to the top of the first slider 412, and a connecting seat 413 is fixedly connected to the side of the cylinder close to the support frame 41. Thus, the cylinder is fixedly connected to the inside of the support frame 41 through the connecting seat 413. Then, the first slider 412 and the first slide rail 411 are movably clamped through a chute. By the cooperation of the first slide rail 411 arranged inside the support frame 41 and the first slider 412 arranged outside the first slide rail 411, and at the same time, the cylinder arranged on the upper part of the first slider 412 controls the first slider 412 to perform reciprocating motion. While driving the rotating mechanism 42, it controls the up and down movement of the clamping mechanism 43, and uses the connecting seat 413 to limit the first slider 412 to prevent the first slider 412 from derailing during reciprocating motion, so as to make the clamping mechanism 43 close to or away from the tank body.

[0043] Specifically refer to the appendix Figure 7 , Figure 8 , outside the first slider 412, there is a rotating mechanism 42. Then, the rotating mechanism 42 includes a rotating head 421 and a controller 422 arranged outside the rotating head 421. At the same time, a rotating groove is opened on one side of the rotating head 421, and a rotor 4211 is movably connected inside the rotating groove.

The first guide rail 433 arranged on one side of the guide rail seat 431 is movably clamped with the second guide rail 4361 arranged on one side of the second slider 436. And through the baffle arranged outside the first guide rail 433 and the stop block 434 arranged between the first guide rails 433, it is convenient for the second slider 436 to be limited during reciprocating motion, and then it is convenient for the first chuck 435 to fix the tank body.

[0046] Specifically refer to the appendix Figure 8 , installation grooves are opened on both sides of the guide rail seat 431, and the guide rail seat 431 is connected with a cylinder through the installation grooves. By using the cylinders arranged at both ends of the guide rail seat 431, the second slider 436 is controlled to perform reciprocating motion, so that the first chuck 435 tightens or loosens the tank body.

[0047] Specifically refer to the appendix Figure 8 , a pressure sensing device is arranged inside the first chuck 435, and the pressure sensing device is connected with a number of first induction probes 4351.

[0053] Refer to the attached Figure 8 、 Figure 10 figure, the clamping mechanism 43 includes a guide rail seat 431, a second chuck 438 provided on the outside of the guide rail seat 431, a third slider 439 provided on the side of the second chuck 438 close to the guide rail seat 431, a second induction probe 4381 provided on the inner wall of the second chuck 438, a second contact pad 4382 provided on the same side as the second induction probe 4381. At the same time, installation slots are opened on both sides of the guide rail seat 431, and the guide rail seat 431 is connected to a cylinder through the installation slots. By using the cylinders provided at both ends of the guide rail seat 431, the third slider 439 is controlled to reciprocate, so that the second chuck 438 tightens or loosens the tank body.

[0054] Specifically refer to the attached Figure 10, a pressure sensing device is provided inside the second chuck 438, and the pressure sensing device is connected with a number of second sensing probes 4381. The second sensing probes 4381 are evenly arranged on the inner side of the second chuck 438. The pressure sensing is used to detect the square tank shell. The slight concavities and convexities generated during the manufacturing process of the square tank shell will be sensed by the second sensing probes 4381, thus excluding the inferior tanks during sampling inspection. In addition, cylindrical through holes matching the second sensing probes 4381 are opened on the outer sides of the second contact pads 4382. The second sensing probes 4381 protrude from the cylindrical through holes and do not extend out of the holes, ensuring that the second sensing probes 4381 will not be damaged and will not cause damage to the square tank shell, so as to detect the square tank shell and exclude the inferior products of the sampled square tanks.

[0055] According to the above structure, through the cooperation of the rotating mechanism 42 and the clamping mechanism 43, the square tank after can making is rotated and fixed, which is convenient for detecting the cover groove at the top of the square tank. At the same time, the square tank shell can be synchronously detected to prevent detection errors and omissions caused by uneven forming of the cover groove depth and the edge thickness of the cover groove of the square tank or deformation of the cover groove. Moreover, the flatness of the square tank shell is detected by the second sensing probes 4381 connected by the pressure sensing device, so as to prevent detection errors and omissions caused by deformation or unevenness of the square tank shell.

[0056] The working principle of the present utility model is as follows:

[0057] Through the rectangular groove opened on the inner side of the box body 31, the rotating shaft 242 and the transmission belt 243 are accommodated therein. At the same time, a rotating rod 32 is arranged in the cylindrical hole. An annular groove matching the rotating shaft 242 is opened on the outer side of the rotating rod 32. Through the rotating shaft 242 and the transmission belt 243 arranged inside the first driving motor 241 and inside the box body 31, the first driving motor 241 drives the rotating rod 32 to perform regular reciprocating motion, and the arc-shaped limiting block 322 is used to detect the uniformity of the cover groove depth and the tank body thickness of the tank body, so as to ensure the flatness and smoothness of the cover groove of the tank body after can making.

[0058] Then, the arc-shaped limiting block 322 performs regular reciprocating rotation in the limiting hole 332. The arc-shaped limiting groove 323 matches the cover groove of the tank body and the edge thickness of the tank body. Thus, the arc-shaped limiting groove 323 rotates on the top of the tank body to detect the cover groove depth and the uniformity of the tank body thickness. If the cover groove is deformed or the thickness is abnormal during the forming of the tank body, the cover groove detection mechanism 3 will stop suddenly and alarm, so as to exclude the inferior products of the tank body after can making.

[0059] Furthermore, a transmission rod 4222 disposed outside the controller 422 and a rotor 4211 connected to the transmission rod 4222 drive the transmission rod 4222 to rotate, thereby driving the rotating mechanism 42 to rotate, further driving the fixture mechanism 43 to complete rotation, and using the control head to stably control the controller 422 to prevent the rotating mechanism 42 from jittering, thereby preventing the tank body from being misaligned.

[0060] Finally, a pressure sensing device is arranged inside the first chuck 435, and the pressure sensing device is connected with a plurality of first induction probes 4351. The pressure sensing is used to detect the cylindrical tank body shell. The fine unevenness generated during the production process of the cylindrical tank body shell can be sensed by the first induction probes 4351, thereby eliminating the inferior tank bodies in the sampling inspection. Moreover, cylindrical through holes matching the first induction probes 4351 are formed on the outer sides of the first contact pads 437. The first induction probes 4351 protrude from the cylindrical through holes and do not extend out of the holes, ensuring that the first induction probes 4351 will not be damaged and will not damage the tank body shell either, thereby detecting the tank body shell and eliminating the defective products of the tank body shell after sampling inspection of can making.
