The cover assembly 23 is disposed on the base 10 and opposite to the base 21, and the cover assembly 23 is disposed on the base 21 to fix the product to the base 21.

In the present embodiment, the number of the positioning members 22 is 6, and for convenience of description, the positioning members 22 are divided into the first positioning members 221 and the second positioning members 222, and the number of the first positioning members 221 and the second positioning members 222 is three. The first positioning piece 221 is fixedly arranged on the substrate 21, the second positioning piece 222 is provided with a waist-shaped hole 2221, the second positioning piece 222 is fixed on the substrate 21 through a bolt, and the second positioning piece 222 is provided with the waist-shaped hole 2221, so that an operator can adjust the fixing position of the second positioning piece 222 through the waist-shaped hole 2221. Because the position of the second positioning member 222 can be adjusted, the carrying assembly 20 can be used for positioning products with different dimensions, so that the versatility of the key detection mechanism 100 is enhanced.

When the product is positioned by the positioning member 22, the cover plate assembly 23 is placed over the product, and the product is secured to the base 21 by the cover plate assembly 23.

In addition, the base 10 is provided with a scanning mechanism (not shown) for scanning the label of each product and uploading the scanned information to the system.

Referring to fig. 2 and 3, in some embodiments, the cover assembly 23 includes a cover 231 and a locking unit 232.

The locking unit 232 is provided to the base 10 for locking the other end of the cover 231 to fix the cover 231 to the carrier assembly 20.

In the present embodiment, the cover assembly 23 further includes a pressing unit 233, where the pressing unit 233 is disposed on a side of the cover 231 facing the substrate 21, and is configured to elastically press against the product when the cover 231 is covered on the product.

When the product is mounted on the base 21, the cover plate 231 is rotated and the cover plate 231 is covered on the product, at this time, the pressing unit 233 on the cover plate 231 abuts against the top surface of the product and presses the product on the base 21, and then the locking unit 232 is used to lock the cover plate 231 to prevent the cover plate 231 from moving, at this time, the product is fixed on the base 21.

Referring to fig. 3, in some embodiments, the pressing unit 233 includes a pressing member 2331 and a pressing elastic member 2332. The pressing piece 2331 is provided at a side of the cover plate 231 facing the base 21.

One end of the pressing elastic member 2332 is connected with the cover plate 231, the other end of the pressing elastic member 2332 is connected with the pressing member 2331, and the pressing elastic member 2332 is used for enabling the pressing member 2331 to elastically press against a product. The pressing elastic member 2332 may be an elastic member such as a spring.

When the cover plate 231 is covered on the product, the pressing piece 2331 elastically presses the product under the elastic action of the pressing elastic piece 2332, and the pressing piece 2331 is elastically abutted with the product, so that the pressing piece 2331 can be effectively prevented from pressing the product, and the purpose of protecting the product is achieved. In this embodiment, the pressing member 2331 may be made of a high-strength adhesive, and since the pressing member 2331 is made of an elastic material, the pressing member 2331 may further prevent the product from being crushed.

Referring to fig. 3 to 5, in some embodiments, the locking unit 232 includes a locking member 2321, a first magnetic member 2322, and a second magnetic member 2323.

The locking member 2321 is rotatably connected to the base 10, and the locking member 2321 abuts against a side of the cover 231 facing away from the base 21 to lock the cover 231.

The first magnetic member 2322 is connected to the locking member 2321, and is located at an end of the locking member 2321 away from the cover plate 231.

The second magnetic element 2323 is disposed on the base 10 and opposite to the first magnetic element 2322, and the polarity of the second magnetic element 2323 is the same as that of the first magnetic element 2322.

When the cover plate 231 is covered on a product, an operator can rotate the locking member 2321 to make the locking member 2321 abut against one side of the cover plate 231, which is away from the substrate 21, at this time, the first magnetic member 2322 and the second magnetic member 2323 are opposite, and since the polarities of the first magnetic member 2322 and the second magnetic member 2323 are the same, the locking member 2321 cannot rotate at will under the action of the first magnetic member 2322 and the second magnetic member 2323, so as to realize self-locking, so that the locking member 2321 firmly abuts against the cover plate 231, so that the cover plate 231 cannot be opened. Because the locking member 2321 is simply self-locking, an operator can conveniently lock the cover 231 or unlock the cover 231.

Referring to fig. 1, 6 and 7, the holding mechanism 30 includes a driving member 31, a transmission member 32 and at least one elastic holding assembly 33. The driving member 31 is spaced apart from the carrier assembly 20.

The transmission piece 32 is connected with the driving piece 31, the transmission piece 32 moves along the first direction under the driving of the driving piece 31, the transmission piece 32 is provided with a sliding groove 321, and the extending direction of the sliding groove 321 is intersected with the first direction.

The elastic supporting component 33 is slidably disposed on the base 10 along the second direction and is located on one side of the carrying component 20, the elastic supporting component 33 is provided with a sliding support portion 3312 inserted into the sliding groove 321, and the sliding support portion 3312 is used for sliding along the extending direction of the sliding groove under the driving of the driving member 32, so that the elastic supporting component 33 is close to the carrying component 20, so as to elastically press the key on the product or keep away from the product on the carrying component 20 to release the key.

In this embodiment, the sliding groove 321 is in a long shape, since the sliding support portion 3312 on the elastic supporting component 33 is inserted into the sliding groove 321 on the driving component 32, when the driving component 31 drives the driving component 32 to move along the first direction (such as the negative direction of the X axis) during the detection process of the key detection mechanism 100, the driving component 32 drives the elastic supporting component 33 to approach the product along the second direction through the sliding groove 321, so that the elastic supporting component 33 can press the key on the product, then the driving component 31 drives the driving component 32 to move reversely along the first direction, so that the elastic supporting component 33 releases the key, and then the pressing process is repeated for multiple times, for example, the key can be pressed 2 times per second. The fact that the key is blocked in the detection process indicates that the key is normal in use, otherwise, the key needs to be reworked again. Because the detection process is not operated by hands, the labor input is reduced, and the labor intensity is reduced. In addition, compared with the manual detection mode, the key detection mechanism 100 can improve the detection efficiency.

In some embodiments, the two sets of elastic supporting components 33 are two sets, the two sets of elastic supporting components 33 are located at opposite sides of the carrying component 20, the two sliding grooves 321 are two, the two sliding grooves 321 are arranged at intervals and the extending directions are intersected, the sliding supporting portions 3312 of the two sets of elastic supporting components 33 are respectively inserted into the two sliding grooves 321, and the two sets of elastic supporting components 33 are driven by the driving member 32 to synchronously approach to the carrying component 20 to press the key, or far from the carrying component 20 to release the key. In other embodiments, the number of resilient abutment members 33 may be four or more. Since the key detection mechanism 100 adopts the two groups of elastic supporting components 33 to detect the keys on two sides of the product simultaneously, the two groups of elastic supporting components 33 improve the detection efficiency of the product.

Referring to fig. 1, 6 and 7, in some embodiments, the elastic supporting component 33 includes a supporting member 331, a supporting member 332 and a supporting elastic member 333.

The support 331 is slidably disposed on the base 10, and the sliding support portion 3312 is disposed on the support 331.

The supporting member 332 is slidably connected to the supporting member 331, and is located at an end of the supporting member 331 away from the sliding supporting portion 3312, and the supporting member 332 is used for pressing the key.

One end of the holding elastic member 333 abuts against the supporting member 331, the other end of the holding elastic member 333 abuts against the holding member 332, and the holding elastic member 333 is used for elastically abutting the holding member 332 against the key. The holding elastic member 333 may be an elastic member such as a spring.

In this embodiment, the support 331 includes a connector 3311 and a boss 3313, for example, a sliding rail may be provided on the base 10, and the sliding rail extends along the second direction. The connecting body 3311 is in a square frame structure, the abutting piece 332 is connected to the top end of the connecting body 3311, the inner side of the connecting body 3311 is slidably connected to a sliding rail, and the sliding rail plays a role in guiding the connecting body 3311, so that the abutting piece 332 can accurately abut against a key. The sliding support portion 3312 has a rod shape, one end of the sliding support portion 3312 is connected to the bottom end of the connecting body 3311, and the other end of the sliding support portion 3312 is slidably inserted into the slide groove 321. When the driving member 31 drives the driving member 32 to move, the driving member 32 drives the sliding support portion 3312 to move through the sliding slot 321, and the sliding support portion 3312 drives the connecting body 3311 to slide along the sliding rail, so that the connecting body 3311 carries the supporting member 332 to press the key.

The protruding portion 3313 is disposed at the top end of the connecting body 3311, one end of the abutting elastic member 333 is connected to the protruding portion 3313, the other end of the abutting elastic member 333 is connected to the abutting member 332, and under the action of the abutting elastic member 333, the abutting member 332 elastically abuts against the key, so that the abutting member 332 does not crush the key, and further the product is protected.

The number of the holding pieces 332 may be plural, the number of the holding elastic pieces 333 is the same as the number of the holding pieces 332 or more than the holding pieces 332, and the plural holding pieces 332 are mounted on the same support 331.

In addition, two holding members 332 may be used to simultaneously hold one key, for example, in the present embodiment, two holding members 332 simultaneously hold two ends of the power key.

The elastic supporting assembly 33 further includes a rotating member 334, the rotating member 334 is rotatably connected to an end of the sliding support portion 3312, and the rotating member 334 abuts against the sliding slot 321. Wherein the rotating member 334 may be a bearing.

When the transmission member 32 drives the sliding support portion 3312 to move through the sliding groove 321, the sliding support portion 3312 slides along the sliding groove 321 relative to the transmission member 32, and by providing the rotation member 334 on the sliding support portion 3312, the sliding friction between the sliding support portion 3312 and the transmission member 32 can be changed into rolling friction, so that the friction force applied to the sliding support portion 3312 is reduced, and the abrasion is further reduced.

Referring to fig. 6-8, in some embodiments, the abutment 332 includes a main body 3321 and a resilient abutment 3322. The main body 3321 is slidably disposed on the support 331.

The elastic supporting body 3322 is connected to one side of the main body 3321 facing away from the supporting elastic member 333, the elastic supporting body 3322 is made of an elastic material, and the elastic supporting body 3322 is used for elastically supporting the key. The elastic supporting body 3322 may be a high-strength adhesive.

In this embodiment, a sliding rail is disposed on the connecting body 3311, the main body 3321 is slidably connected to the connecting body 3311 through the sliding rail, one end of the supporting elastic member 333 is connected to the protruding portion 3313, and the other end of the supporting elastic member 333 is connected to the main body 3321. When the supporting member 332 approaches the product, the elastic supporting body 3322 of the supporting member 332 is pressed against the button of the product. Since the elastic supporting body 3322 is made of an elastic material, when the elastic supporting body 3322 is pressed against the key, the elastic supporting body 3322 can protect the key.

In some embodiments, the elastic supporting body 3322 is provided with two protruding supporting portions 3322a, the two supporting portions 3322a are spaced apart, and the two supporting portions 3322a are used for supporting two ends of the key respectively.

When the elastic supporting body 3322 approaches the key, the two supporting portions 3322a of the elastic supporting body 3322 respectively press the two ends of the key, thereby pressing the key. Because the two ends of the key are stress points, the stress of the key is more balanced when the key is pressed.

Referring to fig. 6 and 7, in some embodiments, the elastic supporting component 33 further includes an adjusting member 335, one end of the adjusting member 335 is slidably connected to the supporting member 331, the other end of the adjusting member 335 is screwed with the supporting member 332, and the adjusting member 335 is used for adjusting the pre-compression force of the supporting elastic member 333 between the supporting member 332 and the supporting member 331. Wherein the adjustment member 335 is a bolt.

In this embodiment, the adjusting member 335 passes through the protruding portion 3313, is screwed with the main body 3321, and is sleeved on the adjusting member 335 by the supporting elastic member 333. When the adjusting member 335 is rotated, the adjusting member 335 adjusts the interval between the main body 3321 and the boss 3313, and when the distance therebetween becomes shorter, the pre-pressure against the elastic member 333 becomes larger, and when the distance therebetween becomes longer, the pre-pressure against the elastic member 333 becomes smaller. Because the products are different, the pressure with which the keys can be pressed is different, and the operator can adjust the pre-pressure of the elastic member 333 according to the detected products. When the pressing force applied to the key is greater than the pre-pressing force of the abutting elastic member 333, the abutting elastic member 333 is compressed, so as to protect the product and prevent the product from being crushed.

Referring to fig. 1, in some embodiments, the display module 40 includes a PLC for controlling the holding mechanism 30 to automatically press a key, and an integrated machine for displaying the operating parameters of the holding mechanism 30.

The key detection mechanism 100 provided in the embodiment of the present utility model generally has the following working procedures:

firstly, a product is placed on a substrate 21, a plurality of positioning pieces 22 on the substrate 21 position the product so that the product is not easy to move at will in the horizontal direction, then a cover plate 231 is rotated and the cover plate 231 is covered on the product, at this time, a pressing piece 2331 elastically presses the product under the action of a pressing elastic piece 2332, and the pressing piece 2331 does not crush the product under the action of the pressing elastic piece 2332, so that the product is protected. When the cover 231 is disposed on the product, the locking member 2321 is rotated to press the locking member 2321 against the cover 231, and at this time, the locking member 2321 performs self-locking under the action of the first magnetic member 2322 and the second magnetic member 2323, so that the cover 231 cannot be opened.

When detecting a key on a product, the driving member 31 drives the driving member 32 to move, the driving member 32 drives the sliding support portion 3312 to move through the sliding slot 321, at this time, the sliding support portion 3312 drives the connecting body 3311 to approach the product, and when the connecting body 3311 drives the main body 3321 to approach the product, the elastic supporting body 3322 on the main body 3321 can press the key and push the key. Then, the driving member 31 drives the driving member 32 to move reversely, so that the driving member 32 can drive the connecting body 3311 to move away from the product, and the elastic supporting body 3322 releases the key, thereby completing one complete pressing detection action, and completing the detection of one product after repeating the detection action for a plurality of times. Since the elastic supporting body 3322 is elastically supported against the key under the action of the supporting elastic member 333 during the detection process, the elastic supporting body 3322 does not crush the key, thereby protecting the key. In addition, by using the key detection mechanism 100 to automatically detect the product, manual operation can be reduced, labor intensity can be reduced, detection efficiency of the product can be improved, and reject ratio of the product can be reduced.
