The inventor of the application finds that the traditional detection mode of manual naked eye detection is still adopted when the appearance of relatively precise products such as a camera module is detected at present. On one hand, the detection efficiency is low in a manual visual detection mode; on the other hand, the visual inspection accuracy is low and continuous inspection for a long time cannot be performed.
In order to solve the above problems, the present inventors propose a product detection device, which includes a feeding device, an appearance detection device and a discharging device, wherein the feeding device is used for feeding a workpiece to the appearance detection device, the appearance detection device can perform appearance detection on the workpiece, and the discharging device classifies the detected workpiece according to the detection result of the appearance detection device so as to remove defective products. The appearance detection device comprises a conveying component and a detection component, wherein the conveying component can automatically carry a workpiece to move to the detection component so as to receive appearance detection. Therefore, the appearance detection of the workpiece can be automatically performed through the detection function of the automatic feeding matched detection assembly, and the efficiency and the accuracy are greatly improved relative to the human eye detection. In addition, the detection efficiency of the appearance detection device can be further improved by increasing the number of workpieces which can be carried by the conveying assembly. However, as the number of workpieces carried by the conveying assembly increases, the process of loading the carriers becomes complicated and affects the efficiency of the detection process due to the need to individually load each carrier of the conveying assembly. Meanwhile, the number of the carriers is increased, and the movement range and flexibility of each carrier are easy to restrict each other.
In order to solve the problems, the inventor of the application performs further optimization on the basis of the product detection equipment, and the feeding assembly is provided with a feeding piece, wherein the feeding piece is used for transmitting a workpiece to a carrier; the carriers are arranged to be able to transfer the workpieces to each other. Therefore, after the workpiece is transferred to one of the carriers by the feeding part, the workpiece can be transferred to other carriers based on the effect that the workpiece can be transferred between the carriers. So set up, need not to set up loading attachment for every carrier is this carrier individual feed to improve the efficiency of material loading, make whole detection efficiency higher. And moreover, the arrangement among the carriers is more orderly and the labor division is clear, so that the overall linkage of the appearance detection device is better. The product inspection apparatus and the appearance inspection device will be described in detail below with reference to specific embodiments and drawings attached to the specification.
Referring to fig. 1 to 3, an embodiment of the present application provides a product appearance detecting apparatus, where the product appearance detecting apparatus 1 includes a feeding device 10, an appearance detecting device 20, and a discharging device 30.
The appearance detection device 20 comprises a base 210, a detection assembly 220 and a material conveying assembly 230, wherein the detection assembly 220 and the material conveying assembly 230 are both arranged on the base 210, and the material conveying assembly 230 is used for bearing a workpiece. The feeding assembly 230 includes a plurality of carriers 2320, and a feeding member 2310 and a discharging member 2330 rotatably disposed on the base 210, wherein rotation axes of the feeding member 2310 and the discharging member 2330 are parallel to each other.
The loading piece 2310 is used for positioning a workpiece on a loading side 2310b of the loading piece 2310, the loading piece 2310 is rotatably disposed on the base 210, and when the loading piece 2310 rotates, the orientation of the loading side 2310b can be adjusted to be used for receiving the workpiece transferred by the loading device 10 and transferring the workpiece to the carrier 2320. In this way, the workpiece can be conveniently transferred from the feeding device 10 to the carrier 2320 by adjusting the orientation of the feeding side 2310b, so that the feeding efficiency is improved. Because the feeding member 2310 can also position the workpiece on the feeding side 2310b, when the feeding member 2310 transfers the workpiece to the carrier 2320, the carrier 2320 can be accurately positioned at an expected position on the carrier 2320, so that a detection effect can be ensured.
The carriers 2320 are located between the feeding part 2310 and the discharging part 2330, and the carriers 2320 are movably disposed on the base 210 to drive the workpiece to approach or depart from the adjacent carriers 2320 and drive the workpiece to move within the detection range of the detection assembly 220. Adjacent carriers 2320 act on different portions of the workpiece, respectively, adjacent carriers 2320 being used to transfer the workpiece to each other.
Since the carriers 2320 are movably disposed on the base 210, and the carriers 2320 are capable of transferring the workpieces to each other, when the workpiece 2310 transfers a workpiece to one of the carriers 2320, the carrier 2320 is capable of transferring the workpiece to the next carrier 2320. In this way, by the function of transferring the workpieces from each carrier 2320 to each other, the workpiece 2310 is transferred to only one carrier 2320, and the workpiece can be transferred to each carrier 2320. Therefore, each carrier 2320 does not need to be fed independently, and the efficiency of workpiece detection efficiency is improved.
Further, adjacent carriers 2320 act on different portions of the workpiece, i.e., the shielding formed by carriers 2320 on the workpiece does not overlap. Therefore, when the adjacent carriers 2320 respectively drive the same or same batch of workpieces to be in the detection range of the detection assembly 220, the detection assembly 220 can detect different areas of the workpieces, so that the comprehensiveness of detecting the appearance of the workpieces is improved. That is, the process in which the workpiece is transferred from one of the carriers 2320 to the next carrier 2320 is not only used for transferring the workpiece but also for turning over the workpiece, so that no additional process is required to turn over the workpiece, thereby improving the detection efficiency of the workpiece.
The blanking member 2330 is rotatably disposed on the base 210 to face the blanking device 30 and the carrier 2320, and the blanking member 2330 receives the workpiece transferred by the carrier 2320, so that the blanking efficiency is improved. In this way, the workpiece after detection can be received and transferred to the discharging device 30 by the discharging member 2330 rotating to face the discharging device 30 or the carrier 2320.
The unloader 30 is used for receiving the work piece transferred by the unloader 2330, the unloader 30 is electrically connected with the detection assembly 220, and the unloader 30 is used for sorting the work piece. That is, after the workpiece is transferred to the blanking device 30 by the blanking member 2330, the blanking device 30 can sort the detected workpiece according to the detection result of the detection assembly 220, so as to sort the good product and the defective product, and improve the yield of the product.
Referring to fig. 3 and 4, in one embodiment, in a direction from the feeding member 2310 to the discharging member 2330, the plurality of carriers 2320 are sequentially arranged, and an arrangement direction of the plurality of carriers 2320 is shown as a reference number K in fig. 3 and 4.
In one embodiment, the loading member 2310 is fixedly disposed on the base 210 for transferring the workpiece. Of course, in some embodiments, the loading member 2310 may be movably disposed on the base 210 to more flexibly transfer the workpiece.
Referring to fig. 4 and fig. 5, in one embodiment, the carrier 2320 includes a first bracket 23210 and a first body 23220, the first bracket 23210 is movably disposed on the base 210, and the first body 23220 is rotatably connected with the first bracket 23210. When the first support 23210 moves relative to the base 210, the first machine body 23220 and the workpiece can be driven to move together, so that the workpiece is in a detection range of the detection assembly 220. Meanwhile, the first support 23210 may further drive the first machine body 23220 to approach the feeding part 2310 or other carriers 2320, so as to transfer the workpiece.
The first machine body 23220 is used for limiting a workpiece on a bearing side 2320a of the first machine body 23220, and the first machine body 23220 is rotationally connected with the first bracket 23210 so as to adjust the direction of the bearing side 2320a, so that the carrier 2320 can conveniently receive the workpiece and conveniently transmit the workpiece to another carrier 2320 or the blanking piece 2330 by reasonably adjusting the direction of the bearing side 2320 a. For example, when each carrier 2320 is arranged in a direction away from the loading member 2310, the first body 23220 is rotated within an angle towards or away from the loading member 2310, such that the carrying side 2320a faces towards the loading member 2310 to receive a transferred workpiece, or such that the carrying side 2320a faces away from the loading member 2310 to transfer a workpiece to a next carrier 2320. Similarly, the carrier 2320 located furthest from the charging member 2310 may transfer a workpiece to the discharging member 2330 when it is facing away from the charging member 2310, to complete the discharging.
Meanwhile, since the first machine body 23220 is used for carrying the workpiece, and the first machine body 23220 can rotate relative to the first bracket 23210, when the workpiece is located in the detection range of the detection assembly 220, the first machine body 23220 can enable the workpiece to face the detection assembly 220 at different angles when rotating relative to the first bracket 23210, so that the detection angle of the detection assembly 220 in detecting the workpiece is increased, and the comprehensiveness of detecting the workpiece is improved.
In one embodiment, the load sides 2320a of adjacent carriers 2320 are used to transfer workpieces to each other when facing each other.
In one embodiment, the rotation axis of the first body 23220 is parallel to the rotation axis of the feeding member 2310, that is, the rotation axes of the feeding member 2310, the first body 23220 of the plurality of carriers 2320, and the discharging member 2330 are parallel to each other. Therefore, the change range of the transmission positions among the feeding piece 2310, the carrier 2320 and the discharging piece 2330 of the workpiece can be reduced, the workpiece can be conveniently transmitted, and the position accuracy of the workpiece can be conveniently improved.
Referring to fig. 3 and 4, in one embodiment, the feeding assembly 230 includes a driving platform 2340, and the driving platform 2340 is disposed on the base 210. The driving platform 2340 is respectively connected to each carrier 2320, so as to respectively drive each carrier 2320 to move relative to the base 210, so that the carriers 2320 can mutually transfer the workpiece, and the carriers 2320 can conveniently drive the workpiece to move within the detection range of the detection assembly 220.
In this embodiment, the first support 23210 of the carrier 2320 may be specifically connected to the driving platform 2340, that is, the driving platform 2340 drives each first support 23210 to move relative to the base 210, so as to drive each carrier 2320 to move on the base 210, so as to realize carrying the workpiece to different positions.
It can be appreciated that the driving manner of the driving platform 2340 for driving each carrier 2320 may be set according to actual requirements, and the direction of movement of each carrier 2320 driven by the driving platform 2340 may be set. For example, the driving platform 2340 may be configured to drive each carrier 2320 to slide in the same direction with respect to the base 210.
Referring to fig. 3 and fig. 4, in one embodiment, the loading member 2310 and the carriers 2320 are sequentially arranged at intervals along the reference direction, and each carrier 2320 is movable relative to the base 210 along the reference direction. In other words, the plurality of carriers 2320 are arranged along the reference direction in a direction away from the feeding member 2310. That is, the driving platform 2340 drives the carriers 2320 to move in the reference direction so as to approach each other or move away from each other. The reference direction is the arrangement direction, and the reference direction is shown as reference number K in fig. 3.
With continued reference to fig. 4 and 5, in one embodiment, the first machine body 23220 includes a housing 23221 and a carrier 23222 for carrying a workpiece, and the carrier 23222 is located on the carrying side 2320a. The housing 23221 is rotatably coupled to the first bracket 23210 about a first axis and the carrier 23222 is rotatably coupled to the housing 23221 about a second axis. The first axis intersects the second axis, i.e., the housing 23221 rotates about the first axis and the carrier 23222 rotates about the second axis, respectively, such that the workpiece is inspected by the inspection assembly 220 at different angles. In this way, the angle of the workpiece detected by the detecting unit 220 can be further increased, so that the detection is finer and more comprehensive.
In addition, since the inspection unit 220 can inspect the workpiece at a plurality of angles, the inspection unit 220 can perform inspection even for some workpieces having complicated shapes. That is, the product adaptability of the appearance inspection device 20 can be improved, and the appearance inspection device 20 can cope with inspection of a plurality of different products. The first axis is shown in fig. 4 and 5 with respect to the central axis C1, and the second axis is shown in fig. 5 with respect to the central axis C2.
Referring to fig. 4 and 6, in one embodiment, the carrier 23222 is disposed on the housing 23221, and the carrier 23222 of at least one carrier 2320 of the carriers 2320 disposed adjacently is retractable with respect to the housing 23221, so that the end of the carrier 23222 near the workpiece is elastically retracted toward the housing 23221 when being pressed. Since the carrier 23222 is used for carrying the workpiece and the carrier 23222 is elastically stretchable when being pressed, the possible impact on the workpiece can be buffered by the elastic stretchable property of the carrier 23222, so as to reduce the probability that the possible impact forces of the carriers 2320 on each other damage the workpiece when the carriers 2320 transfer the workpiece to each other.
Referring to fig. 6, in one embodiment, the carrier 23222 includes an elastic member 23222a, a rotating portion 23222b and a carrier 23222c. The rotating portion 23222b is rotatably connected to the housing 23221 about a second axis, and the carrying portion 23222c is configured to carry a workpiece. The elastic member 23222a is connected between the rotating portion 23222b and the bearing portion 23222c, and the bearing portion 23222c can slide along the rotating portion 23222b in a direction to compress the elastic member 23222a when being pressed. The elastic member 23222a may be a compression spring or other components having elastic properties.
Therefore, when the carriers 2320 mutually transmit the workpieces and the bearing portions 23222c mutually impact, the two bearing portions 23222c can correspondingly retract and elastically compress the elastic member 23222a so as to reduce the impact force applied to the workpieces. It will be appreciated that when the pressure applied to the carrier 23222 is removed, the carrier 23222c can be restored to the pre-pressed position under the action of the elastic member 23222a, so that the consistency of the positions of the workpieces on the carrier 23222 relative to the housing 23221 is high, so as to ensure the detection effect.
Since the rotating portion 23222b is rotatably coupled to the housing 23221, the rotating portion 23222b and the housing 23221 have a stable relative position in a direction other than the rotational direction. The rotation portion 23222b guides and limits the movement of the bearing portion 23222c when pressed, so that the bearing portion 23222c can move stably when pressed and the elastic member 23222a returns to the pre-compression position, thereby improving the workpiece position accuracy.
With continued reference to fig. 6, in one embodiment, one of the bearing portion 23222c and the rotating portion 23222b is provided with a limiting cavity 23222d, and the limiting cavity 23222d has an opening 23222e; the other is provided with a sliding block 23222f, and the sliding block 23222f is extended and arranged in the limiting cavity 23222d through the opening 23222 e. The slider 23222f is slidably engaged with the cavity wall of the retaining cavity 23222d to define the relative movement direction of the bearing portion 23222c and the slider 3326 e.
The elastic member 23222a is disposed in the limiting cavity 23222d, and two ends of the elastic member 23222a respectively abut against the sliding block 23222f and the cavity wall of the limiting cavity 23222d, so that the bearing member 23222 has elastic compression capability. At least a part of the inner peripheral wall of the opening 23222e extends into the opening 23222e to form a stopper 23222g, and the stopper 23222g abuts against a side of the slider 23222f away from the elastic member 23222 a. Thus, the slider 23222f can have a certain stroke in the limiting cavity 23222d by limiting the slider 23222f by the limiting body 23222g, and the bearing portion 23222c and the rotating portion 23222b are prevented from being separated by the elastic member 23222 a.
In the above embodiments, the carrier 23222 itself has elastic expansion and contraction capability. In some embodiments, the carrier 23222 may be integrally movably disposed on the housing 23221, and the elastic member 23222a is connected between the housing 23221 and the carrier 23222, so that the carrier 23222 has an elastic expansion capability relative to the housing 23221.
Referring to fig. 4 and 6, in one embodiment, the carrier 23222 can pick up the workpiece by vacuum suction. The vacuum adsorption pick-up method has low requirements on the structure of the carrier 2320, so that the structure of the carrier 2320 can be designed to be simpler, thereby facilitating the transfer of workpieces between the carrier 2320 and the feeding piece 2310 or the discharging piece 2330 and facilitating the transfer of workpieces between the carriers 2320.
Specifically, the carrier 2320 includes a vacuum generator (not shown, the same applies hereinafter), and an adsorption channel (not shown, the same applies hereinafter) is formed in the carrier 23222, and the adsorption channel has a plurality of adsorption holes 23222h communicating with the outside, so as to form a negative pressure in the adsorption holes 23222 h. Thus, when the work piece covers the suction hole 23222h outside, the negative pressure in the suction passage can suck the work piece onto the carrier 23222.
The number of the adsorption holes 23222h is plural, and the plurality of adsorption holes 23222h are spaced apart from one end of the carrying portion 23222c away from the rotating portion 23222 b. The plurality of suction holes 23222h can have different sizes and can be specifically designed according to the shape of the workpiece to be picked up.
To ensure tightness between the slider 23222f and the cavity wall of the limiting cavity 23222d, a sealing member may be provided on the cavity wall of the slider 23222f and/or the limiting cavity 23222 d. For example, a sealing ring (not shown) may be sleeved on the sliding block 23222f (the same applies below) to improve the sealing performance between the sliding block 23222f and the cavity wall of the limiting cavity 23222 d.
The limiting cavity 23222d can be specifically formed on the carrying portion 23222c, and the rotating portion 23222b includes the slider 23222f. That is, the bearing portion 23222c can be slid with respect to the rotating portion 23222b by being engaged with the rotating portion 23222 b.
Of course, in other embodiments, the first body 23220 may pick up the workpiece in other forms, such as magnetic attraction, clamping by a clamping jaw, and the like.
Referring to fig. 3, in one embodiment, the detecting assembly 220 may include a plurality of detecting modules 2210, and the plurality of carriers 2320 respectively move to positions corresponding to the plurality of detecting modules 2210. In other words, the number of the detection modules 2210 may correspond to the number of the carriers 2320. In this way, on the one hand, the detection module 2210 can detect the workpiece on the corresponding carrier 2320 in a targeted manner, so that the detection accuracy is improved; on the other hand, the idle carriers 2320 are avoided so as to improve the detection efficiency.
It should be noted that, the corresponding relationship between the number of the detection modules 2210 and the number of the carriers 2320 may be flexibly configured according to actual requirements. For example, the detection modules 2210 may be configured to correspond to the carriers 2320 one by one; alternatively, one detection module 2210 may be configured to correspond to a plurality of carriers 2320; alternatively, a plurality of detection modules 2210 may be disposed corresponding to one carrier 2320.

The second body 23120 is configured to position a workpiece on a loading side 2310b of the second body 23120, and the second body 23120 is rotatably connected to the second bracket 23110 to adjust an orientation of the loading side 2310 b. It is appreciated that when the loading side 2310b faces the carrier 2320, the carrier 2320 may remove the workpiece from the second body 23120. When the second body 23120 is rotated to make the feeding side 2310b face the carrier 2320 but face other positions, the specific orientation of the feeding side 2310b can be reasonably adjusted, so that the feeding device 10 can conveniently fill workpieces into the feeding member 2310. In this way, the workpiece can be continuously transferred to the carrier 2320 by correspondingly adjusting the orientation of the feeding side 2310b, so that the appearance detection device 20 can continuously perform appearance detection on the workpiece. The second body 23120 included in the loading device 2310 can rotate about a first rotation axis, which is referred to as the R1 axis in fig. 4, with respect to the second bracket 23110.
In one embodiment, the loading side 2310b and the adjacent load-bearing side 2320a are configured to transfer workpieces to one another when disposed opposite one another.

Thus, when the position of the workpiece is offset from the expected position, the positioning structure 23130 can push the workpiece to move to the expected position when moving relative to the mating member 23121 based on the mating member 23121, and cooperate with the mating member 23121 to position the workpiece at the loading position 2310a, so that the position accuracy of the workpiece is improved, and each carrier 23222 of the carrier 2320 can accurately pick up the workpiece. In addition, since the positioning structure 23130 is respectively surrounded by the plurality of mating members 23121 to form a plurality of loading positions 2310a, that is, only the positioning structure 23130 needs to be driven to simultaneously push the plurality of workpieces, so as to respectively mate with the plurality of mating members 23121 to simultaneously position the plurality of workpieces. So set up, make the structure of material loading piece 2310 simpler, location process is more convenient, swift, and efficiency is higher.

Then, the feeding member 2310 and the first carrier 2320 rotate relative to the base 210, so that the feeding side 2310b and the carrying side 2320a of the first carrier 2320 are opposite to each other, and at this time, the first carrier 2320 can act on the second surface to be inspected 2b to take the workpiece 2 away from the feeding side 2310 b. Subsequently, the first carrier 2320 moves within the detection range of the first detection module 2210 along the reference direction K, so that the first detection module 2210 detects the first surface to be detected 2a, the third surface to be detected 2c, the fourth surface to be detected 2d, the connection between the first surface to be detected 2a and the third surface to be detected 2c, and the connection between the first surface to be detected 2a and the fourth surface to be detected 2d of the workpiece 2. It is appreciated that at any time after the first carrier 2320 picks up the workpiece 2 and until the first carrier 2320 moves within the detection range of the first detection component 220, the orientation of the carrying side 2320a of the first carrier 2320 may be adjusted so that the workpiece 2 located on the carrying side 2320a may be subjected to detection at a desired angular position. Meanwhile, in the detection process, the first machine body 23220 of the first carrier 2320 can be driven to rotate around the first shaft, and the bearing member 23222 of the first carrier 2320 is driven to rotate around the second shaft, so that different surfaces to be detected on the workpiece 2 are adjusted to be capable of being detected at different angles.
When the first detection module 2210 completes detection, the first carrier 2320 and/or the second carrier 2320 move to approach each other. Subsequently, the first carrier 2320 and the second carrier 2320 rotate relative to the base 210, so that the carrying sides 2320a of the first carrier 2320 and the second carrier 2320 are opposite to each other, and thus the second carrier 2320 can act on the first surface 2a to be inspected of the workpiece 2 to pick up the workpiece 2. Afterwards, the second carrier 2320 moves within the detection range of the second detection module 2210 along the reference direction K, so that the second detection module 2210 detects the second surface to be detected 2b, the third surface to be detected 2c, the fourth surface to be detected 2d, the connection between the second surface to be detected 2b and the third surface to be detected 2c, and the second surface to be detected 2b and the fourth surface to be detected 2d of the workpiece 2. In the same manner as the first carrier 2320, at any time from when the second carrier 2320 picks up the workpiece 2 to when the second carrier 2320 moves within the detection range of the second detection component 220, the orientation of the carrying side 2320a of the second carrier 2320 may be adjusted, so that the workpiece 2 located on the carrying side 2320a may be detected at an expected angular position. Meanwhile, in the detection process, the first machine body 23220 of the second carrier 2320 can be driven to rotate around the first shaft, and the bearing member 23222 of the second carrier 2320 is driven to rotate around the second shaft, so that different surfaces to be detected on the workpiece 2 are adjusted to be capable of being detected at different angles.
When the second detecting assembly 220 completes the detection, the carrying side 2320a of the second carrier 2320 may be adjusted toward the blanking member 2330, so that the blanking member 2330 can take the workpiece 2 from the second carrier 2320.

Since the matching piece 23121 is used for bearing the workpiece, and the matching piece 23121 can elastically stretch and retract towards the base plate 23122 when being pressed, the impact possibly received by the workpiece can be buffered by the elastic stretch property of the matching piece 23121, so that the probability that the workpiece is damaged due to the impact possibly received by the feeding piece 2310 and the carrier 2320 when the workpiece is transmitted by the feeding piece 2310 and the carrier 2320 is reduced.
In one embodiment, the mating member 23121 can be specifically configured to resiliently retract toward the base 23122 when the end of the base 23121a adjacent to the workpiece is pressurized.
