Detailed Description

The technical solutions in the specific embodiments of the present invention will be clearly and completely described below, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example one

Fig. 1 shows an embodiment of the present invention, and in this embodiment, it should be noted that, in order to describe the technical solution more specifically, the steps described in this embodiment do not strictly correspond to the steps described in the content of the present invention.

The utility model provides a device for detecting the front and back sides of a product, which comprises a double-side detection mechanism as shown in figure 1; wherein, two-sided detection mechanism contains station carousel, moves material mechanism, detects piece, upset module 5 and cleaning mechanism group. Further, the material moving mechanism is a feeding manipulator and a discharging manipulator in this embodiment. Of course, in other embodiments, the material moving mechanism may be a single robot, and one robot is used to complete the loading and unloading of the product. In other embodiments, the material moving mechanism is a feeding manipulator and a discharging manipulator, and the feeding manipulator and the discharging manipulator can be located at the same position outside the station turntable, i.e. the feeding and discharging of the product are performed at the same station. Preferably, the loading mechanical rear and the unloading mechanical hand are located at different positions outside the station turntable, as in the present embodiment: the feeding mechanical arm, the detection camera 3, the discharging mechanical arm, the overturning module 5, the ultrasonic cleaning unit 6 and the alcohol cleaning unit 7 are sequentially arranged around the station turntable in the clockwise direction. In this embodiment, the feeding robot is a six-axis robot feeding module 2, and the discharging robot is a four-axis robot 4, wherein the interval angle between the six-axis robot feeding module 2, the inspection camera 3, the four-axis robot 4, the turnover module 5, the ultrasonic cleaning unit 6, and the alcohol cleaning unit 7 is 60 °. Of course, in other embodiments, the spacing angle between the six-axis robot feeding module 2, the inspection camera 3, the four-axis robot 4, the flipping module 5, the ultrasonic cleaning mechanism 6 and the alcohol cleaning mechanism 7 is 60 °, however, the disclosure is not limited thereto, and the spacing angle between the six-axis robot feeding module 2, the inspection camera 33, the four-axis robot 4, the flipping module 5, the ultrasonic cleaning unit 6 and the alcohol cleaning mechanism 7 in the clockwise direction may be other angles to achieve the object of the present invention.

When the six-axis manipulator feeds the product sucked from the tray of the upstream platform onto the station turntable, the six-axis manipulator feeding module 3 overturns the product to enable the reverse side of the product to be upward, and then the product is placed on the station turntable in a state that the reverse side is upward. As shown in fig. 2, in this embodiment, 6 stations are provided on the station turntable, wherein each station is provided with a number 1 jig position and a number 2 jig position, that is, there are two jig positions on each station. Corresponding induction devices are installed below each jig position and used for transferring information about whether products are placed in the jigs to other devices. Preferably, in other embodiments, the station turntable station can be provided with four or eight stations; of course, each station can be provided with three or four jig positions.

In this embodiment, the six-axis manipulator feeding module 3 places the first product to be detected in the fixture 1011 No. 1 of the first station of the six-station turntable 1 in a state that the reverse side is upward, and the product rotates clockwise along with the six-station turntable 1 to the position of the detection camera 3. Because the detection camera 3 is fixed on the frame of the detection piece, as shown in fig. 5, the tool 1 can be driven by the driving device arranged at the bottom of the six-station turntable 1 to move in the first station, so as to move the product to the detection position of the detection camera 3, and the detection camera 3 receives information from the sensor below the tool 1 1011 to detect the back side of the product in the tool 1 1011. After the reverse side detection is finished, the product rotates to the position of the four-axis manipulator 4 along with the six-station turntable 1 in the No. 1 jig 1011, at the moment, the product does not perform the blanking action because the product is not subjected to the front side detection, and the product continues to rotate to the overturning module 5 along with the six-station turntable 1.

As shown in fig. 6, the turnover module 5 includes a turnover mechanism 501 and a pick-and-place mechanism 502, and when the product is transferred to the turnover module 5 along with the six-station turntable 1, the pick-and-place mechanism 502 of the turnover module 5 takes out the product from the six-station turntable 1 and places the product in a jig placing rack of the turnover mechanism 501. The turnover mechanism 501 turns the jig placing rack 180 degrees, and changes the product from the reverse side upward state to the front side upward state. Because the jig placing frame is adopted for overturning, the jig placing frame is hardly influenced by the specification and the size of a product, only the corresponding jig plate needs to be changed, and the overturning mechanism 501 can be compatible with different products, especially can be completely compatible under the conditions of different specifications and sizes of similar products; therefore, the detection equipment using the turnover mechanism can quickly realize the replacement of models when different products are detected, effectively reduces the equipment acquisition cost and the equipment storage management cost of manufacturers, and is suitable for popularization and application.

After the turnover mechanism 501 finishes turnover of the product, the pick-and-place mechanism 502 sucks the product with the upward front from the jig placing frame in the turnover mechanism 501, moves to the position right above the No. 2 jig 1012 at the first station of the six-station turntable 1, and places the product with the upward front in the No. 2 jig 1012 at the first station.

The product in the first station No. 2 tool 1012 with the upward front surface continues to rotate to the ultrasonic cleaning mechanism 6 along with the six-station turntable 1. The ultrasonic cleaning mechanism 6 is provided with a fan assembly and a dust collecting device, and the fan assembly and the dust collecting device are controlled by a driving device in the ultrasonic cleaning mechanism 6. The ultrasonic cleaning mechanism 6 starts to start after receiving information of a sensor below the No. 2 jig 1012 from the first station, the front of a product is cleaned by the aid of the air knife assembly, and meanwhile, dust generated in the cleaning process is collected by the dust collecting device to guarantee stable operation of equipment. In this embodiment, when the six-axis manipulator feeding module 11 feeds the jig 1011 No. 1 at the first station, the turntable starts, the downstream devices do not start at the same time, and the downstream devices need to start after receiving the information of the existing products in the jig sent by the sensor below the corresponding jig. In this embodiment, when the jig 1011 of the first station 1 is rotated to the ultrasonic cleaning mechanism 6, the ultrasonic cleaning mechanism 6 is not activated because no product is placed in the jig 1011 of the first station 1.

After the ultrasonic cleaning mechanism 6 finishes cleaning, the product with the upward front surface placed in the No. 2 jig 1012 of the first station continues to rotate to the downstream alcohol cleaning mechanism 7 along with the six-station turntable 1. The sensor below No. 2 tool 1012 at the first station transmits the information that the product is in the tool to the alcohol cleaning mechanism 7, and the alcohol cleaning mechanism 7 starts to start after receiving the information. The clean mechanism 7 of alcohol is provided with and places the mechanism including driving piece, moving mechanism and alcohol, and clean mechanism 7 of alcohol utilizes the dustless cloth that the driving piece drive was placed on moving mechanism to clean the front of product in No. 2 tool 1012 of first station, cleans it and carries out the alcohol after finishing. After cleaning, the six-station turntable 1 rotates again.

Six station carousel 1 rotates and gets back to six manipulators material loading module 11 departments after the round, and six manipulators material loading module 11 carries out the material loading for the second time to vacant tool 1011 No. 1 in the first station, all placed the product in two tools in the first station this moment, and the product in tool 1011 No. 1 is reverse side upwards, and the product in tool 1012 No. 2 is positive upwards. After the feeding is finished, the six-station turntable 1 continues to rotate to the position of the detection camera 3. The detection camera 3 carries out reverse side detection on products in the No. 1 jig 1011 at the first station. The first station No. 2 jig 1012 is driven by the bottom driving device to move to the detection position of the detection camera 3, and the detection camera 3 detects the front of the product in the first station No. 2 jig 1012 to complete the front and back detection of the product in the first station No. 2 jig 1012.

The six-station turntable 1 continues to rotate to the four-shaft mechanical arm 4. The four-axis manipulator 4 receives information from a sensor below the first station No. 2 jig 1012 to start, and sucks and places a product which is subjected to front and back detection from the first station No. 2 jig 1012 into a downstream working platform. The six-station turntable 1 for detecting the front side and the back side of a product needs to rotate more than one circle. In this embodiment, the rotation angle of the six-station rotary table 1 for completing front and back detection of one product is 480 °, which greatly shortens the time for completing front and back detection of a single product, namely the sum of the time required for completing steps from all original mechanisms for completing front and back detection of a single product and the time required for rotating the rotary table to each mechanism, and the sum of the time required for completing the most complex instruction function, namely the sum of the time required for turning over a single cycle of a module and the time required for rotating the rotary table by 60 °, and greatly shortens the time required for detecting a single cycle of front and back detection of a product.

The six-axis manipulator feeding module 2 places the product on the six-station turntable 1 in a state that the front surface of the product is upward. In this embodiment, two jig positions, i.e., No. 1 jig 1011 and No. 2 jig 1012, are provided at each station. Of course, in other embodiments, three or four jig positions may be provided for each station. The six-axis manipulator feeding module 2 feeds a product to the jig 1011 at the first station in a state that the front surface of the product faces upwards, the six-station turntable 1 rotates the jig 1011 at the first station to rotate to the ultrasonic cleaning unit 6 for cleaning for the first time, and the six-axis manipulator feeding module 2 feeds the jig 1 at the second station. After the first cleaning is finished, the product 1011 in the jig 1 at the first station is rotated to the alcohol cleaning unit 7 for secondary cleaning, and the product in the jig 1 at the second station is cleaned for the first time at the ultrasonic cleaning unit 6. After the secondary cleaning is finished, the product of 1011 in the No. 1 jig of the first station rotates to the detection camera 3, and the detection camera 3 detects the front of the product by moving to the detection position of the detection camera 3 under the driving of the jig bottom driving device. The product in the tool 1011 of 1 number of the first station rotates to upset module 5 department after positive detection, and upset module 5 overturns 180 through the product in tilting mechanism 501 in with tool 1, then returns the product after the reversal to original tool 1011 number 1 through getting and putting mechanism 502.

Further, the product that has finished overturning rotates to the six-axis manipulator feeding module 11 along with the six-station turntable 1, the six-axis manipulator feeding module 11 feeds the No. 2 jig 1012, and the product is fed in a state that the front surface is upward. After the feeding is finished, the products with the upward back surfaces in the jig 1011 and the upward front surfaces in the jig 1012 1 and the products with the upward front surfaces in the jig 1012 continue to rotate to the ultrasonic cleaning unit 6 and the alcohol cleaning unit 7 along with the six-station turntable 1, and the products with the upward front surfaces in the jig 6 2 are cleaned. After the cleaning, the ascending product of 1011 reverse side in 1 tool and the ascending product of 1012 obverse side in No. 2 tool continue to rotate to detection camera 3 department along with six station carousel 1, and detection camera 3 carries out the reverse side to the ascending product of reverse side in No. 1 tool 1011 earlier and detects, and No. 2 tool 1012 carries out the position switch under bottom drive arrangement's drive afterwards, moves to the detection position that detects camera 3, and detection camera 3 carries out the obverse side to the ascending product of obverse side in No. 2 tool 1012 and detects. After the detection is finished, products with upward back surfaces in the No. 1 jig 1011 and products with upward front surfaces in the No. 2 jig 1012 continue to rotate to the position of the four-shaft mechanical arm 4 along with the six-station turntable 1, and when the four-shaft mechanical arm 4 senses that products exist in the No. 2 jig 1012, the products with the detected front surfaces and the detected back surfaces in the No. 1 jig 1011 are discharged. In this embodiment, the front and back sides of a product are inspected for its angular position of 600 ° as it rotates with the six-station turret.

Of course, in other embodiments, eight stations are provided on the station turntable, and each station is provided with four jig positions, two No. 1 jig positions and two No. 2 jig positions.

After the detection of one side is completed, the turntable continues to rotate to the turning module 5, and the turning mechanism 501 of the turning module 5 synchronously turns over two products in the two jig numbers 1 1011. After the turning is completed, the pick-and-place mechanism 502 of the turning module places the turned 2 products into two No. 2 jigs 1012. The eight-station turntable rotates to the position of the six-axis manipulator feeding module 11, and the six-axis manipulator feeding module feeds two vacant No. 1 jigs 1011.

EXAMPLE III

The method for detecting the front and back surfaces of the product by the single camera is used for detecting the front and back surfaces of the product by the device for detecting the front and back surfaces of the product.

The feeding manipulator takes out the product from the upstream jig tray and turns the product 180 degrees before feeding, so that the product is placed in the No. 1 jig 1011 of the first station of the station turntable at the feeding port in a reverse side-up state. In order to improve the utilization rate of the corresponding device in the embodiment, the product is uniformly turned over during feeding, so that the product is fed in a reverse side-up state. In other embodiments, the product is not turned during loading, and the product is placed in the jig of the station turntable in a front-up state. The positions of the material moving mechanism, the detection camera 3 and the turning module 5 are correspondingly adjusted to realize the front and back detection of the product.

After the feeding action is finished, the turntable rotates to a detection station along the clockwise direction, and a detection camera 3 fixed at the detection station is ready for detection after receiving information; as shown in fig. 4, a jig cylinder below the station turntable drives the jig 1011 # 1 to move to the detection position of the detection camera 3 on the station; the detection camera 3 performs reverse detection on the product.

And then, after the detection is finished, the station turntable continuously rotates to the four-axis manipulator 4. Since no product is placed in the No. 2 jig 1012, the four-axis robot 4 does not operate, that is, does not perform a blanking operation. The station turntable continues to rotate to the turnover module 5, the turnover mechanism 501 in the turnover module 5 turns over the product in the jig 1011 No. 1 by 180 degrees, and the product is turned from a state that the back surface is upward to a state that the front surface is upward. The pick-and-place mechanism 502 of the turnover module 5 places the turned product in a state of front side up into the No. 2 fixture 1012 of the station turntable.

Subsequently, the station turntable is rotated to the station of the ultrasonic cleaning mechanism 6. The ultrasonic cleaning mechanism 6 receives a signal from a sensor under the No. 2 jig 1012, and starts to clean a product placed in the No. 2 jig 1012 with an upward front surface for the first time. After the first cleaning, the station turntable continues to rotate to the station of the alcohol cleaning mechanism 7, the alcohol cleaning mechanism 7 starts to start after receiving a signal of the sensor below the No. 2 jig 1012, and the product with the upward front surface in the No. 2 jig 1012 is cleaned for the second time.

After the two cleaning processes, the station turntable continues to rotate to the position of the six-axis manipulator feeding module 11, and the empty jig 1011 No. 1 is fed again. Then, the station turntable rotates to the position of the detection camera 3, the detection camera 3 carries out reverse detection on the product in the No. 1 jig 1011, then the No. 2 jig 1012 moves relatively, the detection camera 3 carries out front detection on the product in the No. 1 jig 1011,

then, the station turntable continues to rotate to the four-axis manipulator 4, and after receiving the information from the lower part of the No. 2 jig 1012, the four-axis manipulator 4 feeds the product which is detected on the front side and the back side in the No. 2 jig 1012. In the embodiment, the angle of the front and back detection of a single product along with the rotation of the station turntable is 480 degrees, and when any peripheral mechanism on the outer side of the station turntable runs, other mechanisms synchronously work, so that the synchronous operation of nine stations by using six stations is realized, the standby state of mechanisms such as a detection camera and an overturning module is avoided, the time required by the detection period of the single product is shortened, and the utilization rate of related mechanisms arranged on the periphery on the outer side of the station turntable is improved. The time for completing the front and back detection of a single product is shortened to the sum of the time for completing the most complex instruction function and the time for rotating the turntable for one station from the sum of the time required by all the original mechanisms for completing the steps and the time required by rotating the turntable to each mechanism. If the time that the instruction function was accomplished to the upset module is the longest in this embodiment, then the time of accomplishing single product detection is the sum of the time that upset module 5 accomplished a cycle of upset product and the time that the carousel rotated to upset module 5 from the unloading station, has improved detection efficiency when shortening product detection time.
