In order to make the present application clear, elements not related to the description are omitted from the details of this specification.

[0097] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0098] The present application discloses a detection mechanism including a clamping assembly and a detection assembly. The clamping assembly is used to clamp a product. The clamping assembly includes a fixing member, a bearing member, a first pressing member, a second pressing member, a first elastic member, a second elastic member and a clamping drive unit. Among them, the bearing member is arranged on one side of the fixing member in the second direction, and the bearing member is provided with a clamping area, a first fixing part and a second fixing part on the side away from the fixing member in the second direction. The clamping area is used to accommodate the product, the first fixing part is located on one side of the clamping area in the third direction, and the second fixing part is located on one side of the clamping area in the first direction. The first pressing member is movably arranged at the top of the fixing member, and the first pressing member is located on the side of the bearing member in the third direction away from the first fixing part. The first elastic member is arranged on the side of the first pressing member in the third direction away from the bearing member, and the two ends of the first elastic member are respectively connected to the first pressing member and the fixing member. The second pressing member is movably arranged at the top of the fixing member, and the second pressing member is located on the side of the bearing member in the first direction away from the second fixing part. The second elastic member is arranged on a side of the second pressing member away from the bearing member in the first direction, and the two ends of the second elastic member are respectively connected to the second pressing member and the fixing member. The clamping drive unit is arranged on the fixing member, and the clamping drive unit is configured to drive the first pressing member and the second pressing member to move outside the clamping area to vacate the clamping area to place the product and compress the first elastic member and the second elastic member respectively. The first elastic member and the second elastic member are configured to push the first pressing member and the second pressing member to move and press the product to the first fixed part and the second fixed part respectively. The detection component includes a displacement sensor and a probe. The displacement sensor is located on one side of the clamping component and extends toward the clamping component in the first direction. The displacement sensor is provided with a telescopic rod that moves in the first direction. The probe is fixedly connected to the telescopic rod and is used to contact the surface of the product. The telescopic rod is configured to be driven by an external force to move the probe in the first direction, and the displacement sensor is configured to detect the distance moved by the telescopic rod in the first direction.

[0099] The detection mechanism of the above embodiment uses a clamping assembly to clamp the product, and drives the first pressing member and the second pressing member to push the product in the third direction and the first direction respectively through external force, so that the product is relatively fixed to the first fixing part and the second fixing part respectively, so as to achieve the purpose of accurately clamping the product with smaller size. The telescopic rod drives the probe to move toward the product until the probe contacts the surface of the product, and the displacement sensor detects the moving distance of the probe, thereby obtaining the detection distance when the probe moves to contact the product, so as to achieve the effect of high-precision detection of the product size, and can achieve the measurement size of less than 10mm with an accuracy of 0.02mm.

[0100] Some embodiments of the present application will be described below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0101] See also Figure 1, a detection device 10 is provided, which includes a discharging mechanism 11, a storage mechanism 13, a feeding mechanism 14 and a detection mechanism 12. In a third direction Z, the discharging mechanism 11, the detection mechanism 12 and the storage mechanism 13 are arranged in sequence. The discharging mechanism 11 is configured to deliver products 20 in sequence. The detection mechanism 12 is configured to detect the size of the product 20. The storage mechanism 13 is configured to store the product 20 detected by the detection mechanism 12. The feeding mechanism 14 is configured to be movably arranged in the third direction Z, and the feeding mechanism 14 feeds the product 20 delivered by the storage mechanism 13 to the clamping assembly 121, and the feeding mechanism 14 also feeds the product 20 after the detection on the clamping assembly 121 to the storage mechanism 13.

[0102] The first direction X and the third direction Z are perpendicular.

[0103] When the detection device 10 is working, the feeding mechanism 14 transfers the product 20 sent by the discharging mechanism 11 to the detection mechanism 12 for detection. After the detection mechanism 12 completes the detection of the size of the product 20, the feeding mechanism 14 transfers the detected product 20 to the storage mechanism 13 for storage, and the cycle is repeated in sequence. Thus, the detection device 10 can automatically detect the size of the product 20, and the detection efficiency of the detection device 10 is improved.

[0104] In some embodiments, see Figure 2 and Figure 3 , the detection mechanism 12 includes a clamping assembly 121 and a detection assembly 122. The clamping assembly 121 is used to clamp the product 20. The detection assembly 122 includes a displacement sensor 1221 and a probe 1222. The displacement sensor 1221 is located at one side of the clamping assembly 121 and extends toward the clamping assembly 121 in the first direction X. An end of the displacement sensor 1221 close to the clamping assembly 121 is provided with a telescopic rod 1223 that moves in the first direction X. The probe 1222 is fixedly connected to the telescopic rod 1223, and the probe 1222 is used to contact the surface of the product 20. The telescopic rod 1223 is configured to be driven by an external force to move the probe 1222 in the first direction X, and the displacement sensor 1221 is configured to detect the distance moved by the telescopic rod 1223 in the first direction X.

[0105] Before the detection mechanism 12 works, the position of the probe 1222 is calibrated, and the telescopic rod 1223 is driven by an external force to move the probe 1222 to a specified position relative to the displacement sensor 1221. At this time, the displacement sensor 1221 detects that the distance moved by the telescopic rod 1223 to drive the probe 1222 is the initial position, that is, the probe 1222 is at the zero position. When the detection mechanism 12 works, the clamping assembly 121 is used to clamp the smaller product 20 to solve the problem that it is difficult to clamp the smaller product 20 manually. The telescopic rod 1223 drives the probe 1222 to move closer to the product 20 until the probe 1222 contacts the surface of the product 20. The displacement sensor 1221 detects the moving distance of the probe 1222, thereby obtaining the moving distance of the probe 1222 when it moves to contact the product 20. An external control center is used to calculate the difference between the moving distance of the probe 1222 detected by the displacement sensor 1221 and the initial position of the probe 1222. When the difference is within a specified range, it indicates that the size of the product 20 is qualified. When the difference exceeds the specified range, it indicates that the size of the product 20 is unqualified, thereby achieving the effect of automatic detection of the size of the product 20 by the detection mechanism 12 and improving the automation function of the detection mechanism 12.

[0106] The use of a probe 1222 with a smaller diameter can reduce the contact area between the probe 1222 and the surface of the smaller product 20, which helps to improve the accuracy of the contact between the probe 1222 and the detection position on the surface of the product 20, and reduces the error of the detection mechanism 12 in detecting the size of the smaller product 20. The telescopic rod 1223 automatically drives the smaller probe 1222 to move, so as to achieve a high-precision detection effect on the size of the product 20, and can achieve a measurement size of less than 10 mm with an accuracy of 0.02 mm.

[0107] In some embodiments, see Figure 3 The detection component 122 further includes a mobile driving unit 1224 and a lifting driving unit 1225. The mobile driving unit 1224 is connected to the displacement sensor 1221, and the mobile driving unit 1224 is configured to drive the displacement sensor 1221 to move in the third direction Z. The lifting driving unit 1225 is connected to the mobile driving unit 1224, and the lifting driving unit 1225 is configured to drive the mobile driving unit 1224 to move in the second direction Y.

[0108] The first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0109] The mobile driving unit 1224 is used to drive the displacement sensor 1221 to drive the telescopic rod 1223 and the probe 1222 to move in the third direction Z to adjust the position of the probe 1222 in the third direction Z. At the same time, the lifting and moving unit is used to drive the mobile driving unit 1224 to drive the displacement sensor 1221 to move up and down in the second direction Y. The displacement sensor 1221 drives the telescopic rod 1223 and the probe 1222 to move up and down in the second direction Y to adjust the position of the probe 1222 in the second direction Y, thereby achieving the effect of the probe 1222 accurately contacting the detection position of different products 20 or different detection positions of the same product 20.

[0110] In some embodiments, the mobile driving unit 1224 and the lifting driving unit 1225 are respectively high-precision linear transmission mechanisms such as linear motors or slide cylinders.

The supporting member 1212 is arranged on the top of the fixing member 1211. The top of the supporting member 1212 is provided with a clamping area 12121, a first fixing portion 12123 and a second fixing portion 12124. The clamping area 12121 is used to accommodate the product 20. The first fixing portion 12123 is located on one side of the clamping area 12121 in the third direction Z, the second fixing portion 12124 is located on one side of the clamping area 12121 in the first direction X, the fixing member 1211 is provided with a third fixing portion 12111 and a fourth fixing portion 12112, the third fixing portion 12111 is located on one side of the supporting member 1212 in the third direction Z away from the first fixing portion 12123, the fourth fixing portion 12112 is located on one side of the supporting member 1212 in the first direction X away from the first fixing portion 12123 On one side of the second fixed portion 12124, the first pressing member 1213 is movably disposed between the first fixed portion 12123 and the third fixed portion 12111, the first elastic member 1215 is disposed between the first pressing member 1213 and the third fixed portion 12111, and the two ends of the first elastic member 1215 are respectively connected to the first pressing member 1213 and the third fixed portion 12111, and the second pressing member 1214 is movably disposed between the second fixed portion 12124 and the fourth fixed portion 12112. The second elastic member 1216 is disposed between the second pressing member 1214 and the fourth fixed portion 12112, and the two ends of the second elastic member 1216 are respectively connected to the second pressing member 1214 and the fourth fixed portion 12112. The clamping drive unit 1217 is disposed on the fixed portion 1211, and the clamping drive unit 1217 is respectively connected to the first pressing member 1213 and the second pressing member 1214.

[0112] The second direction Y is parallel to the gravity direction, and the first direction X and the third direction Z are horizontal directions.

[0113] When the loading mechanism 14 places the product 20 in front of the clamping area 12121, the clamping drive unit 1217 simultaneously drives the first pressing member 1213 and the second pressing member 1214 to move, so that the first pressing member 1213 and the second pressing member 1214 respectively move from the inside of the clamping area 12121 to the outside of the clamping area 12121 to vacate the clamping area 12121, and the first pressing member 1213 compresses the first elastic member 1215, and the second clamp compresses the second elastic member 1216, so that the loading mechanism 14 can place the product 20 in the clamping area 12121.

[0114] After the loading mechanism 14 places the product 20 in the clamping area 12121 , the driving force of the clamping driving unit 1217 is cancelled. The first elastic member 1215 and the second elastic member 1216 push the first pressing member 1213 and the second pressing member 1214 to move respectively under the action of their own elasticity, and the first pressing member 1213 and the second pressing member 1214 move respectively from the outside of the clamping area 12121 to the inside of the clamping area 12121 until the first pressing member 1213 acts on the product 20 in the clamping area 12121, and the first pressing member 1213 pushes the product 20 to contact with the first fixing portion 12123, so that the first fixing portion 12123 and the product 20 are relatively fixed, and the second pressing member 1214 acts on the product 20 in the clamping area 12121, and the second pressing member 1214 pushes the product 20 to contact with the second fixing portion 12124, so that the second fixing portion 12124 and the product 20 are relatively fixed, thereby realizing the function of the clamping assembly 121 to automatically clamp the product 20. The first fixing portion 12123 and the second fixing portion 12124 are in contact with the product 20 respectively, and respectively limit the smaller product 20, so that the clamping component 121 can accurately clamp the smaller product 20 in the clamping area 12121, which helps to improve the accuracy of the detection component 122 in detecting the size of the product 20.

[0115] In some embodiments, when the first pressing member 1213 and the second pressing member 1214 push the product 20 toward the first fixing portion 12123 and the second fixing portion 12124 respectively, the loading mechanism 14 acts on the product 20 in the second direction Y to increase the pressure between the product 20 and the carrier 1212, thereby reducing the gap between the product 20 and the carrier 1212, so that the product 20 is in full contact with the carrier 1212, so as to improve the stability of the product 20 placed in the clamping area 12121.

[0116] In some embodiments, see Figure 4The clamping assembly 121 also includes a linkage structure 1218, and the linkage structure 1218 includes a guide block 12183, a first linkage rod 12181 and a second linkage rod 12182. In the second direction Y, the guide block 12183 is arranged between the fixing member 1211 and the supporting member 1212, the guide block 12183 is fixedly connected to the fixing member 1211, the supporting member 1212 is fixedly connected to the guide block 12183, the third fixing portion 12111 and the fourth fixing portion 12112 are respectively fixedly connected to the guide block 12183, and guide grooves 121831 for the first linkage rod 12181 and the second linkage rod 12182 to slide are respectively provided on the guide block 12183. The first linkage rod 12181 has two opposite ends in the third direction Z, one end of the first linkage rod 12181 is connected to the first pressing member 1213, and the other end of the first linkage rod 12181 extends from the guide groove 121831 to the outside of the guide groove 121831 and is connected to the clamping drive unit 1217. A first inclined surface 121811 is provided in the middle of the first linkage rod 12181, and the second linkage rod 12182 has two opposite ends in the first direction X, one end of the second linkage rod 12182 is connected to the second pressing member 1214, and the other end of the second linkage rod 12182 is provided with a second inclined surface 121821, and the second inclined surface 121821 contacts the first inclined surface 121811.

[0117] When the feeding mechanism 14 places the product 20 in front of the clamping area 12121, the clamping drive unit 1217 drives the first linkage rod 12181 to move in the first direction X, and the first linkage rod 12181 drives the first pressing member 1213 to move away from the carrier 1212. The first inclined surface 121811 applies a force to the second inclined surface 121821 in the first direction X, so that the first linkage rod 12181 pushes the second linkage rod 12182 to move in the first direction X. Then, the second pressing member 1214 is driven to move away from the supporting member 1212, so that one clamping drive unit 1217 simultaneously drives the first pressing member 1213 and the second pressing member 1214 to move from the inside of the clamping area 12121 to the outside of the clamping area 12121 respectively. Compared with using two clamping drive units 1217 to drive the first pressing member 1213 and the second pressing member 1214 respectively, it helps to reduce the number of components of the detection device 10, making the structure of the detection device 10 simpler and more compact.

[0118] In some embodiments, the guide block 12183 and the fixing member 1211 are integrally provided to improve the strength of the connection between the guide block 12183 and the fixing member 1211 .

[0119] In some embodiments, see Figure 7The discharging mechanism 11 includes a material receiving component 112 and a material discharging component 111. The material receiving component 112 is arranged on a side of the detection mechanism 12 away from the storage mechanism 13. A material discharging area 113 is arranged between the material receiving component 112 and the detection mechanism 12. The material discharging component 111 is arranged between the material receiving component 112 and the material discharging area 113.

[0120] Specifically, the material receiving assembly 112 is a material receiving mechanical arm 1121 and a material receiving driving unit 1122. The material receiving driving unit 1122 drives the material receiving mechanical arm 1121 to reciprocate in the third direction Z, and a material receiving space 11211 is provided at the top of one end of the material receiving mechanical arm 1121. The material discharging assembly 111 is a vibration plate, and the material discharging port of the vibration plate extends in the first direction X to the moving path of the material receiving mechanical arm 1121, and the material discharging port of the vibration plate is located above the material receiving space 11211. When the material discharging mechanism 11 is working, the vibration plate sequentially conveys the product 20 to the material receiving space 11211 of the material receiving mechanical arm 1121, and when the product 20 falls into the material receiving space 11211 under the action of gravity, the material receiving driver drives the material receiving mechanical arm 1121 to drive the product 20 to move to the material discharging area 113, so that the loading mechanism 14 moves to the material discharging area 113 and obtains the product 20 in the material receiving space 11211. After the loading mechanism 14 acquires the product 20 , the material receiving driving unit 1122 and the material receiving mechanical arm 1121 move and reset in the third direction Z so that the vibration plate can transport the product 20 to the material receiving space 11211 again.

[0121] The setting of using the receiving component 112 to transfer the product 20 from the discharging component 111 to the discharging area 113 is used to extend the distance between the discharging component 111 and the detection mechanism 12, so that the discharging component 111 avoids the detection mechanism 12, which helps to avoid interference between the discharging component 111 and the detection mechanism 12. In addition, the setting of the loading mechanism 14 to obtain the product 20 in the discharging area 113 helps the loading mechanism 14 avoid the discharging end of the discharging component 111, so that the discharging detection component 1111 is set above the discharging port of the discharging component 111, and the discharging detection component 1111 is used to detect whether the discharging component 111 has discharged the product 20 into the receiving space 11211, which is conducive to reducing the idling of the loading robot arm 1121.

[0122] In some embodiments, see Figure 8 The material storage mechanism 13 includes two material storage containers 131 and a material storage driving unit 132. The two material storage containers 131 are spaced apart in the first direction X, and the material storage driving unit 132 is arranged between the two material storage containers 131. The material storage driving unit 132 is used to release the qualified or unqualified products 20 into the two material storage containers 131 respectively, so as to achieve the purpose of classified storage of the qualified or unqualified products 20.

[0123] Specifically, a storage area 133 is provided between the two storage containers 131, and the plane where the storage area 133 is located is higher than the ports of the two storage containers 131 in the second direction Y. The storage drive unit 132 includes two blowing nozzles 1321 arranged above the storage area 133 in the second direction Y, and the two blowing nozzles 1321 are respectively arranged on both sides of the storage area 133 in the first direction X, and the two blowing nozzles 1321 are respectively inclined downward and facing the storage area 133. When the feeding mechanism 14 releases the product 20 after the inspection to the storage area 133, since the weight of the smaller product 20 is lighter, one of the blowing nozzles 1321 blows the product 20 on the storage area 133 according to the result of the inspection mechanism 12, and blows the product 20 into one of the storage containers 131, so as to achieve the effect that the storage drive unit 132 releases the qualified or unqualified products 20 into the two storage containers 131 respectively.

[0124] In some embodiments, see Fig. 9 The feeding mechanism 14 includes an adsorption component 141, a first drive unit 142, and a second drive unit 143. The adsorption component 141 is connected to the first drive unit 142. The first drive unit 142 is connected to the second drive unit 143. When the feeding mechanism 14 obtains the product 20, the second drive unit 143 drives the first drive unit 142 to move in the third direction Z, so that the first drive unit 142 drives the adsorption component 141 to move in the third direction Z to above the discharge area 113 or the clamping area 12121, and the first drive unit 142 drives the adsorption component 141 to descend close to the product 20 on the discharge area 113 or the clamping area 12121 to reduce the distance between the adsorption component 141 and the product 20, which helps the adsorption component 141 to adsorb the product 20, thereby achieving the function of the feeding mechanism 14 to obtain the product 20.

[0125] In addition, due to the small size of the product 20, when clamping and obtaining the product 20, it is necessary to align the product 20 precisely, and it is easy to get pinched during the clamping and moving process. Therefore, compared with the clamping method, the method of obtaining the product 20 by adsorption only requires the product 20 to be close to the adsorption area to obtain the product 20, and the atmospheric pressure acts on the product 20, which can effectively reduce the risk of the product 20 being pinched when moving.

[0126] When the loading mechanism 14 releases the product 20, the first driving unit 142 drives the adsorption component 141 to rise so that the adsorption component 141 is away from the discharge area 113 or the clamping area 12121, and the second driving unit 143 drives the first driving unit 142 to move in the third direction Z, so that the first driving unit 142 drives the adsorption component 141 to move in the third direction Z to above the clamping area 12121 or the storage area 133, and the first driving unit 142 drives the adsorption component 141 to descend close to the clamping area 12121 or the storage area 133 to reduce the distance between the product 20 and the clamping area 12121 or the storage area 133. When the product 20 is located in the clamping area 12121 or the storage area 133, the adsorption component 141 is vacuumed to eliminate the pressure difference on both sides of the product 20 in the second direction Y, and the product 20 falls from the adsorption component 141 to the clamping area 12121 or the storage area 133 under the action of gravity, thereby achieving the function of the loading mechanism 14 releasing the product 20.

[0127] The feeding mechanism 14 adopts an adsorption method to obtain the product 20 , which helps to reduce the risk of the product 20 being easily damaged due to clamping relative to the direction of clamping the product 20 .

[0128] In some embodiments, see Figures 9 to 11 The adsorption component 141 includes a suction nozzle 1412 and a mounting member 1411. The mounting member 1411 is connected to the first driving unit 142, and the suction nozzle 1412 is arranged on the mounting member 1411. The portion of the suction nozzle 1412 extends below the mounting member 1411 in the second direction Y. A cavity 14121 for accommodating a portion of the product 20 is provided at the bottom of the suction nozzle 1412. The cavity 14121 is connected to an external negative pressure source, and a negative pressure is formed in the cavity 14121 under the action of the external force. When the first driving unit 142 drives the mounting member 1411 to move, and the mounting member drives the suction nozzle 1412 to approach the product 20, a pressure difference is formed on both sides of the product 20, and the product 20 is pushed by the atmospheric pressure and enters the cavity 14121, so that the product 20 is adsorbed by the suction nozzle 1412, thereby achieving the purpose of the adsorption component 141 obtaining the product 20.

[0129] In addition, when the suction nozzle 1412 contacts the product 20, the suction nozzle 1412 is extended below the mounting member 1411 in the second direction Y, which helps the suction nozzle 1412 to be closer to the product 20 relative to the mounting member 1411, so that there is a gap between the mounting member 1411 and the product 20 or the outside world, thereby reducing the risk of collision between the mounting member 1411 and the outside world.

[0130] In some embodiments, see Fig. 9 and Fig.10The mounting member 1411 is provided with a vacuum regulating structure 1414 which is connected to the cavity 14121. Specifically, the vacuum regulating structure 1414 is a vacuum breaking valve. When the suction nozzle 1412 releases the product 20, the external negative pressure source stops providing negative pressure to the cavity 14121, and the vacuum breaking valve connects the cavity 14121 with the atmosphere to destroy the negative pressure in the cavity 14121, thereby eliminating the pressure difference on both sides of the product 20. Under the action of gravity, the product 20 falls from the cavity 14121 and separates from the suction nozzle 1412.

[0131] In some embodiments, see Fig. 9 and Fig.10 The mounting member 1411 is provided with a through hole (not marked) for the suction nozzle 1412 to pass through in the second direction Y, and the suction nozzle 1412 is provided with a boss 14122 on the side away from the cavity 14121 in the second direction Y, and the projection of the boss 14122 in the first direction X is located outside the through hole, and the mounting member 1411 is provided with a covering member 14111 at the top in the second direction Y, and the covering member 14111 covers the boss 14122. The adsorption assembly 141 also includes a third elastic member 1413, which is located between the covering member 14111 and the boss 14122 in the second direction Y, and the two ends of the third elastic member 1413 are respectively connected to the covering member 14111 and the boss 14122. When the mounting member 1411 drives the suction nozzle 1412 to approach the product 20 in the second direction Y until the product 20 contacts the suction nozzle 1412, or the mounting member 1411 drives the suction nozzle 1412 to push the product 20 toward the supporting member 1212, the product 20 will support the suction nozzle 1412 and move the suction nozzle 1412 relative to the mounting member 1411. The suction nozzle 1412 compresses the third elastic member 1413, and the suction nozzle 1412 is buffered by the third elastic member 1413, thereby reducing the hard contact between the product 20 and the suction nozzle 1412, thereby reducing the risk of damage to the product 20 due to excessive pressure.

[0132] In some embodiments, the first elastic member 1215 , the second elastic member 1216 and the second elastic member 1216 are all compression springs.

[0133] In some embodiments, see Fig. 9, there are two suction nozzles 1412, and the two suction nozzles 1412 are spaced apart in the third direction Z. The spacing between the two suction nozzles 1412, the spacing between the discharge area 113 and the clamping area 12121, and the spacing between the clamping area 12121 and the storage area 133 are equal. When the adsorption component 141 obtains the product 20, the mounting member 1411 drives the two suction nozzles 1412 to move, and makes one of the suction nozzles 1412 close to the discharge area 113, and the other suction nozzle 1412 close to the clamping area 12121, so that one suction nozzle 1412 can adsorb the product 20 in the discharge area 113, and at the same time, the other suction nozzle 1412 adsorbs the product 20 in the clamping area 12121, so that the adsorption component 141 can simultaneously obtain the products 20 in two different positions. When the adsorption component 141 releases the product 20, the mounting part 1411 drives the two suction nozzles 1412 to move, and one of the suction nozzles 1412 drives the product 20 close to the clamping area 12121, and the other suction nozzle 1412 drives the product 20 close to the storage area 133, so that one suction nozzle 1412 releases the product 20 obtained from the discharge area 113 to the clamping area 12121, and at the same time, the other suction nozzle 1412 releases the product 20 obtained from the clamping area 12121 to the storage area 133, so as to achieve the purpose of the adsorption component 141 releasing the two products 20 to different positions at the same time.

[0134] In some embodiments, the clamping drive unit 1217, the first drive unit 142, the second drive unit 143 and the material receiving drive unit 1122 are respectively drive devices with output reciprocating force, such as cylinders, electric pushers or linear motors.

[0135] The working process of the detection mechanism 12 of the present application is as follows:

[0136] When the loading mechanism 14 places the product 20 in front of the clamping area 12121, the clamping drive unit 1217 simultaneously drives the first pressing member 1213 and the second pressing member 1214 to move, so that the first pressing member 1213 and the second pressing member 1214 move from the inside of the clamping area 12121 to the outside of the clamping area 12121 respectively, and the first pressing member 1213 compresses the first elastic member 1215, and the second clamp compresses the second elastic member 1216.

[0137] After the loading mechanism 14 places the product 20 in the clamping area 12121, the driving force of the clamping driving unit 1217 is canceled. The first elastic member 1215 and the second elastic member 1216 respectively push the first pressing member 1213 and the second pressing member 1214 to move under the action of their own elasticity, and the first pressing member 1213 and the second pressing member 1214 respectively move from the outside of the clamping area 12121 to the inside of the clamping area 12121. The first pressing member 1213 moves to the point where the first pressing member 1213 acts on the product 20 in the clamping area 12121, and the first pressing member 1213 pushes the product 20 to contact the first fixing portion 12123, so that the first fixing portion 12123 and the product 20 are relatively fixed; the second pressing member 1214 moves to the point where the second pressing member 1214 acts on the product 20 in the clamping area 12121, and the second pressing member 1214 pushes the product 20 to contact the second fixing portion 12124, so that the second fixing portion 12124 and the product 20 are relatively fixed.

[0138] When the product 20 is clamped and fixed, the telescopic rod 1223 drives the probe 1222 to move closer to the product 20 until the probe 1222 contacts the surface of the product 20 , and the displacement sensor 1221 detects the moving distance of the probe 1222 .

[0139] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application, and are not intended to limit the present application. As long as they are within the essential scope of the present application, appropriate changes and modifications to the above embodiments are within the scope disclosed in the present application.
