Description

Technical Field

[0001] The present application relates to the technical field of automated product detection, and in particular to a transfer device and detection equipment. Background Art

[0002] With the development of science and technology, automated production is becoming increasingly common. Automated production generally refers to the process by which machinery, equipment, systems, or processes achieve desired goals through automated detection, information processing, analysis, judgment, and manipulation and control, with minimal or no human involvement. During the production process, products are carried by carriers, which have a defined positioning space to locate and accommodate the product, providing some protection while facilitating its movement.

[0003] In the existing technology, when a product is processed in multiple aspects, one carrier cannot meet the needs. It is often necessary to take out multiple products from one carrier and transfer them to another carrier. The transfer process is time-consuming and labor-intensive, resulting in low product transfer efficiency and affecting work efficiency.

[0004] In addition, in the inspection equipment, the inspection device must not only perform back-end appearance inspection on the product carried on the carrier, but also detect the contour of the product through the backlight source. The accuracy requirements for product contour detection are high, and the positioning accuracy of existing carriers often cannot be controlled within a relatively precise range. On the other hand, during the carrier docking process, the two docking carriers must not only achieve smooth transfer of the product, but also ensure that the product is firmly fixed, otherwise it is easy to cause the product to fall.

[0005] Therefore, there is an urgent need for a transfer device and a detection device to solve the above technical problems. Summary of the Invention

[0046] like Figures 1 to 7 As shown, the present application provides a transfer device for use in the field of industrial automation and in industries such as 3C. The transfer device includes a conveying mechanism 100 extending along a first direction and a carrier assembly arranged on the conveying mechanism 100. The carrier assembly includes at least two carriers, and the conveying mechanism 100 can independently drive each carrier to move back and forth along the first direction. Specifically, the carrier includes a carrier, a driving mechanism and a fixing mechanism. A product station for accommodating products is provided on the carrier, the driving mechanism is used to drive the carrier to flip between a docking position and a non-docking position, and the fixing mechanism is provided on the carrier to fix the product; when the carriers of two adjacent carriers are flipped to the corresponding docking positions, the conveying mechanism 100 is used to drive the two carriers to dock, so as to transfer the product on one of the carriers to the other carrier, thereby completing the synchronous transfer of multiple products.

In addition, the clamping mechanism 24 can position the product in a precise position range to ensure detection accuracy.

[0048] Optionally, in one embodiment of the present application, the carrier assembly includes three carriers arranged in sequence along the first direction, wherein the two carriers at the two end positions are each provided with an adsorption mechanism 14, the carrier at the middle position is provided with a clamping mechanism 24, and one of the two carriers at the two end positions corresponds to the loading station, and the other corresponds to the unloading station. In this way, the product can be reliably fixed throughout the entire process of loading, processing, and unloading, thereby improving the reliability of the product processing and transfer process. Of course, in other embodiments, the three carriers can also be provided with a clamping mechanism 24 on the two carriers at the two end positions, and an adsorption mechanism 14 on the carrier at the middle position, and one of the two carriers at the two end positions corresponds to the loading station, and the other corresponds to the unloading station, which can also improve the reliability of the product processing and transfer process. It should be noted that in actual production, according to usage requirements, the number of carriers can also be set to other numbers, such as two, four, five, etc., and is not limited to this embodiment.

[0049] Optionally, in one embodiment of the present application, the conveying mechanism 100 is a linear motor module, including a linear guide rail extending in a first direction, a slider, a stator assembly and a mover assembly, etc. Each carrier in the carrier assembly is slidably connected to the linear guide rail through a slider, and the mover assembly can drive each carrier to move back and forth along the first direction. This embodiment adopts a linear motor module with a compact structure and strong adaptability. It can improve the motion accuracy and operation stability of the carrier, and it is convenient to set up multiple movers for independent control, which can meet complex motion requirements. Furthermore, the linear motor module of this embodiment has three independently controlled movers, and the three movers are respectively connected to the above-mentioned three carriers in a one-to-one correspondence to independently drive the three carriers to move back and forth along the first direction respectively.

[0050] refer to Figure 1-Figure 7 As shown, the following content of this application is described by taking an example in which a carrier assembly includes a first carrier 1, a second carrier 2 and a first carrier 1 arranged in sequence along a first direction.

[0051] In one embodiment of the present application, the conveying mechanism 100 is provided with a loading station, a first inspection station, a second inspection station and an unloading station in sequence along the first direction. Figure 1 The first carrier 1 at the middle left end is a loading carrier, which is used to receive products at the loading station and transport the products to the second carrier 2; the second carrier 2 is an inspection carrier, which can receive products on the first carrier 1, and complete the inspection of the back and outline of the product at the first inspection station, and then transport the product to the first carrier 1 on the right end; the first carrier 1 on the right end is an inspection unloading carrier, which can receive products on the second carrier 2, and complete the inspection of the front of the product at the second inspection station, and then transport the product to the unloading station to complete the unloading operation.

[0052] In one embodiment of the present application, the first carrier 1 includes a first base 11, a first platform 12, a first driving mechanism 13 and an adsorption mechanism 14. The first base 11 serves as a supporting structure for the first carrier 1 and is transmission-connected to the mover of the conveying mechanism 100. A first workstation for accommodating products is provided on the first platform 12. Specifically, a plurality of first workstations are provided on the first platform 12 so that multiple products can be carried for processing at the same time. The first driving mechanism 13 is fixed to the first base 11 and is used to drive the first platform 12 to rotate. Specifically, the first platform 12 of the first carrier 1 for loading can rotate between a loading position and a first docking position. Optionally, in one embodiment of the present application, when the first platform 12 is in the loading position, the front of the first platform 12 faces upward and is in a horizontal state; when the first platform 12 is in the first docking position, the front of the first platform 12 faces the second carrier 2 and is in a vertical state so as to dock with the second carrier 2. The suction mechanism 14 is provided on the first carrier 12 and corresponds to the first station, and is used to stably suck the product and prevent it from falling. Specifically, the suction mechanism 14 includes multiple vacuum suction cups, which are arranged one-to-one with the multiple first stations to ensure good suction and fixation of each product.

[0053] Optionally, the first carrier 1 further includes a first mounting base 15 and a first rotating frame 16. The first mounting base 15 is fixed to two sides of the first base 11. Both ends of the first rotating frame 16 are rotatably connected to the first mounting base 15. The bottom of the first carrier 12 is fixed to the first rotating frame 16. With this arrangement, the first rotating frame 16 can drive the first carrier 12 to rotate within a range of 180 degrees relative to the first mounting base 15.

[0054] Optionally, in one embodiment of the present application, the first driving mechanism 13 includes a first motor 131, a first synchronous belt 132, a first driving wheel 133, and a first driven wheel 134. The first motor 131 is fixed to the first base 11, the first driving wheel 133 and the first driven wheel 134 are both rotatably mounted in the first mounting seat 15, and the first driven wheel 134 is spaced apart above the first driving wheel 133. The output shaft of the first motor 131 is transmission-connected to the first driving wheel 133, the first driving wheel 133 and the first driven wheel 134 are connected via the first synchronous belt 132, and the first driven wheel 134 is transmission-connected to the first rotating frame 16. The first driving mechanism 13 has precise transmission, high efficiency, and convenient control, ensuring precise adjustment of the rotation angle of the first carrier 12.

[0055] Furthermore, the first carrier 1 also includes a first sensor 17, which is a position sensor installed on one side of the first mounting seat 15 and is used to detect the flip position of the first carrier 12. The first sensor 17 is electrically connected or signal-connected to the controller. When the first sensor 17 detects that the first carrier 12 flips to the loading position or the first docking position, it can feedback a signal to the controller to control the first drive mechanism 13 to stop rotating, thereby ensuring the rotation position accuracy of the first carrier 12. In addition, the first carrier 1 also includes a first elastic buffer assembly, which is arranged on the first carrier 12 and is used to buffer the product. Specifically, the first elastic buffer assembly includes a slide rail arranged in the first carrier 12, a slider slidingly arranged on the slide rail, and a spring connected between the slider and the first carrier 12, wherein the extension direction of the slide rail is perpendicular to the bearing surface of the first carrier 12, and the first station is connected to the slider. This arrangement allows the product to be subjected to a certain elastic buffering effect when the product is placed on the first station, thereby avoiding hitting the hard limit and accidentally damaging the product.

[0056] In one embodiment of the present application, the second carrier 2 includes a second base 21, a second platform 22, a second driving mechanism 23 and a clamping mechanism 24. The second base 21 serves as a supporting structure for the second carrier 2, and is transmission-connected to the mover of the conveying mechanism 100. A second workstation for accommodating products is provided on the second platform 22. Specifically, a plurality of second workstations are provided on the second platform 22 so that multiple products can be carried for processing at the same time. The second driving mechanism 23 is fixed to the second base 21, and is used to drive the second platform 22 to rotate between the second docking position, the first detection position and the third docking position. Optionally, in this embodiment, when the second platform 22 is in the second docking position, the front of the second platform 22 faces the first carrier 1 for loading and is in a vertical state, so as to dock with the first platform 12 in the first docking position to transfer the product; when the second platform 22 is in the first detection position, the front of the second platform 22 faces upward and is in a horizontal state, so as to facilitate the detection device to detect the product; when the second platform 22 is in the third docking position, the front of the second platform 22 faces the first carrier 1 for unloading and is in a vertical state, so as to dock with the first carrier 1 for unloading.

[0057] In one embodiment of the present application, at the first inspection station, the inspection device not only performs an appearance inspection on the back of the product on the second carrier 2, but also detects the contour of the product through the backlight source. The accuracy requirement for product contour detection is relatively high. If a suction cup is used to fix the product, the positioning accuracy cannot be controlled within a relatively precise range. On the other hand, during the carrier docking process, if both docked carriers use suction cups to absorb the product, the product may fall when the docking is completed and the vacuum is removed. To solve the above problem, the second carrier 2 of this embodiment is provided with a clamping mechanism 24. Optionally, the clamping mechanism 24 is provided in multiple groups, and corresponds one-to-one to multiple second stations, for positioning and clamping multiple products. This embodiment can firmly clamp the product by providing the clamping mechanism 24 to prevent the product from falling during the docking transfer process, and the clamping mechanism 24 can position the product in a precise position range to ensure detection accuracy. Specifically, the clamping mechanism 24 includes a clamping cylinder 241 and a clamping jaw 242. The clamping cylinder 241 is fixed to the second carrier 22, and the clamping jaw 242 is located at the actuating end of the clamping cylinder 241. The clamping cylinder 241 can drive the clamping jaw 242 to move toward or away from the product, thereby clamping and releasing the product. Optionally, a buffer structure can also be provided within the clamping mechanism 24 to protect the product from damage during the process of clamping and positioning the product.

[0058] Optionally, the second carrier 2 further includes a second mounting base 25 and a second rotating frame 26. The second mounting base 25 is fixed to two sides of the second base 21. Both ends of the second rotating frame 26 are rotatably connected to the second mounting base 25. The bottom of the second platform 22 is fixed to the second rotating frame 26. With this arrangement, the second rotating frame 26 can drive the second platform 22 to rotate within a range of 180 degrees relative to the second mounting base 25.

[0059] Optionally, in one embodiment of the present application, the second drive mechanism 23 includes a second motor 231, a second synchronous belt 232, a second driving wheel 233, and a second driven wheel 234. The second motor 231 is fixed to the second base 21, the second driving wheel 233 and the second driven wheel 234 are both rotatably mounted in the second mounting seat 25, and the second driven wheel 234 is spaced apart above the second driving wheel 233. The output shaft of the second motor 231 is transmission-connected to the second driving wheel 233, the second driving wheel 233 and the second driven wheel 234 are connected via the second synchronous belt 232, and the second driven wheel 234 is transmission-connected to the second rotating frame 26. The second drive mechanism 23 has precise transmission, high efficiency, and convenient control, ensuring precise adjustment of the rotation angle of the second carrier 22.

[0060] Furthermore, the second carrier 2 also includes a second sensor 27, which is a position sensor installed on one side of the second mounting seat 25 and is used to detect the flip position of the second carrier 22. The second sensor 27 is electrically connected or signal-connected to the controller. When the second sensor 27 detects that the second carrier 22 flips to the second docking position, the first detection position or the third docking position, it can feedback a signal to the controller to control the second drive mechanism 23 to stop rotating, thereby ensuring the rotation position accuracy of the second carrier 22. In addition, the second carrier 2 also includes a second elastic buffer assembly, which is arranged on the second carrier 22 and is used to buffer the product. Specifically, the second elastic buffer assembly includes a slide rail arranged in the second carrier 22, a slider sliding on the slide rail, and a spring connected between the slider and the second carrier 22, wherein the extension direction of the slide rail is perpendicular to the bearing surface of the second carrier 22, and the second station is connected to the slider. This arrangement allows the product to be subjected to a certain elastic buffering effect when it is placed on the second station, thereby avoiding hitting the hard limit and accidentally damaging the product.

[0061] In one embodiment of the present application, the first carrier 1 for unloading and the first carrier 1 for loading have the same structure, the difference being that the first platform 12 of the first carrier 1 for unloading can rotate between the fourth docking position, the second detection position and the unloading position. Optionally, in the first carrier 1 for unloading, when the first platform 12 is in the fourth docking position, the front of the first platform 12 faces the second carrier 2 and is in a vertical state, so as to dock with the second platform 22 in the third docking position to transfer the product; when the first platform 12 is in the second detection position, the front of the first platform 12 faces upward and is in a horizontal state, so as to facilitate the detection device to detect the product; when the first platform 12 is in the unloading position, the front of the first platform 12 faces upward or toward the side away from the second carrier 2 to complete the unloading of the product.

[0062] Furthermore, the first carrier 1 for unloading is also provided with a first sensor 17. When the first sensor 17 detects that the first carrier 12 is flipped to the fourth docking position, the second detection position or the unloading position, it can feedback a signal to the controller to control the first driving mechanism 13 to stop rotating, thereby ensuring the rotation position accuracy of the first carrier 12.

[0063] One embodiment of the present application further provides a testing device, comprising a testing device and the transfer device of embodiment 1. The platform of at least one carrier in the transfer device can be flipped between a testing position and a docking position, and the testing device is used to test the product on the platform in the testing position.

[0064] In one embodiment of the present application, the conveying mechanism 100 is provided with a loading station, a first inspection station, a second inspection station and an unloading station in sequence along the first direction. Figure 1The first carrier 1 at the middle left end is a loading carrier, which is used to receive products at the loading station and transport the products to the second carrier 2; the second carrier 2 is an inspection carrier, which can receive products on the first carrier 1, and inspect the back and outline of the products through the inspection device at the first inspection station, and then transport the products to the first carrier 1 at the right end. The first carrier 1 at the right end is an inspection and unloading carrier, which can receive products on the second carrier 2, and inspect the front of the products through the inspection device at the second inspection station, and then transport the products to the unloading station to complete the unloading operation. Specifically, the first carrier 12 of the first carrier 1 for loading can rotate between the loading position and the first docking position; the second carrier 22 of the second carrier 2 can rotate between the second docking position, the first inspection position and the third docking position; the first carrier 12 of the first carrier 1 for unloading can rotate between the fourth docking position, the second inspection position and the unloading position.

[0065] In order to improve the detection accuracy of the detection device for the product, in one embodiment of the present application, the second carrier 2 also includes a carrier positioning cylinder 28. The carrier positioning cylinder 28 is fixed on the second base 21. The action end of the carrier positioning cylinder 28 is provided with a positioning pin 281, and the bottom of the second carrier 22 is provided with a positioning hole; when the second carrier 22 rotates to the first detection position, the carrier positioning cylinder 28 can be actuated to insert the positioning pin 281 into the positioning hole. In this way, the second carrier 22 is accurately positioned at the first detection position, so that the second carrier 22 can remain horizontal and prevent the position error of the second carrier 22 from affecting the detection effect. It should be noted that in other embodiments, the carrier positioning cylinder 28 can also be set on other carriers to achieve the positioning of the corresponding carrier position and improve the product processing effect, which is not limited to this embodiment.

[0066] Optionally, in one embodiment of the present application, the second carrier 2 further includes a first light source assembly 29, which is fixed to the second carrier 22 and is used to illuminate the bottom of the product on the second carrier 22, thereby facilitating the detection device to obtain product contour information to detect whether the product is qualified. Optionally, the first light source assembly 29 is a bar light source.

[0067] Furthermore, at the second inspection station, the inspection device also performs an appearance inspection on the front of the product on the first carrier 1 for unloading. To this end, the first carrier 1 for unloading also includes a second light source assembly, which is fixed to the first carrier 12 and is used to illuminate the bottom of the product on the first carrier 12, facilitating the inspection device to obtain product appearance information and verify whether the product is qualified.

[0068] Optionally, in one embodiment of the present application, the detection device is a camera (including a 2D camera and a 3D camera), which can be set above the second carrier 2 and the first carrier 1 for unloading through a gantry, and can detect the product by taking downward photos to obtain product information.

[0069] The working process of the detection equipment provided in this application is as follows:

[0070] After the first carrier 1 for loading arrives at the loading station, its first drive mechanism 13 drives the first carrier 12 to flip to the loading position, and then the adsorption mechanism 14 is activated to achieve one-time loading of multiple products through vacuum adsorption; after loading is completed, the first drive mechanism 13 drives the first carrier 12 to flip to the first docking position. At the same time, the second drive mechanism 23 of the second carrier 2 drives the second carrier 22 to flip to the second docking position, and then the mover of the conveying mechanism 100 drives the first carrier 1 to move to the first inspection station to achieve docking between the first carrier 1 and the second carrier 2. When the product is placed on the second carrier 22, the clamping mechanism 24 is activated to clamp and position the multiple products to prevent them from falling; then the adsorption mechanism 14 of the first carrier 1 for loading is closed, the adsorption of the products stops, and the conveying mechanism 100 drives the first carrier 1 back to the loading station.

[0071] Next, the second drive mechanism 23 of the second carrier 2 drives the second platform 22 to flip to the first inspection position. At this point, the carrier positioning cylinder 28 activates, positioning the second platform 22 via the positioning pin 281, keeping it horizontal. The inspection device then inspects the back of the product. Simultaneously, the first light source assembly 29 activates to illuminate the bottom of the product. The 3D camera inspects the product's height and flatness, while the 2D camera inspects the product's contours. After inspection, the second drive mechanism 23 drives the second platform 22 to flip to the third docking position. Simultaneously, the first drive mechanism 13 of the first carrier 1 for unloading drives the first platform 12 to flip to the fourth docking position. The conveyor mechanism 100 then drives the second carrier 2 to the second inspection station, docking the second carrier 2 with the first carrier 1 for unloading. Once the product is placed on the first platform 12, the suction mechanism 14 activates, securing the product through vacuum suction. The clamping mechanism 24 then closes to release the product, and the conveyor mechanism 100 drives the second carrier 2 back to the first inspection station.

[0072] Next, the first drive mechanism 13 of the first carrier 1 for unloading drives the first platform 12 to flip to the second inspection position. Simultaneously, the second light source assembly activates to illuminate the bottom of the product. The inspection device performs a final inspection of the front of the product and feeds the inspection results back to the controller to distinguish between good and defective products for easy tray unloading. After inspection, the first drive mechanism 13 drives the first platform 12 to flip to the unloading position. The conveyor mechanism 100 then drives the first carrier 1 to the unloading station, completing the product unloading operation.
