[0061] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0062] See also Figure 1 、 Figure 2 and Figure 3 The embodiment of the present application provides a detection device 100, which includes a frame 10, a transmission component 20, a lifting component 30, a stop component 40, a clamping component 50, a detection component 60 and a push component 70. The detection device 100 is used to detect a product 200. Please refer to Figure 2 The product 200 includes a first workpiece 201 and a second workpiece 202. The first workpiece 201 has a mounting hole 2011. The second workpiece 202 covers the mounting hole 2011 and is bonded to the first workpiece 201. For example, the first workpiece 201 can be a back panel of a tablet computer, and the second workpiece 202 can be a logo.

[0063] It can be understood that a three-dimensional coordinate system is established in some of the drawings in this application, and the first direction is Figure 1 The X-axis direction is shown, and the second direction is Figure 1 The Y-axis direction shown, the third direction is Figure 1 In the Z-axis direction shown, the X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other.

[0064] See also Figure 1 The frame 10 has a detection position 11, and the transmission component 20 is arranged on the frame 10 for transmitting the product 200 along the first direction. The lifting component 30 is arranged below the transmission component 20 and connected to the frame 10. The lifting component 30 is used to lift the transmission component 20 to lift the product 200. The stop component 40 is spaced apart from the detection position 11 along the first direction and connected to the frame 10. The stop component 40 is used to stop the product 200 transmitted by the transmission component 20 from reaching the detection position 11. Please refer to Figure 3 and Figure 4The clamping assembly 50 includes a carrier 51, a clamping drive 52, a linkage 53, and two clamping members 54. The carrier 51 is located at the detection position 11 and connected to the frame 10. The carrier 51 has a through hole 511. The carrier 51 is used to receive the fallen product 200 and carry the first workpiece 201. The clamping drive 52 is located on the carrier 51 and connected to the linkage 53. The two clamping members 54 are movably connected to the linkage 53. The clamping drive 52 drives the linkage 53 to drive the two clamping members 54 to move relative to each other synchronously to clamp the first workpiece 201, or to move away from each other synchronously to release the first workpiece 201. Figure 3 、 Figure 5 and Figure 6 The detection assembly 60 includes a pressing member 61 and a negative pressure detection member 62. The pressing member 61 is connected to the carrier 51 and is used to press the first workpiece 201 to the carrier 51. The pressing member 61 has a receiving groove 611 connected to the external vacuum member. The receiving groove 611 is used to cover the second workpiece 202 under the drive of the pressing member 61 and form a negative pressure environment under the conduction of the external vacuum member. The negative pressure detection member 62 is connected to the receiving groove 611 and is used to monitor the negative pressure information of the receiving groove 611. Please refer to Figure 3 The push assembly 70 is movably disposed in the through hole 511 and connected to the frame 10. The push assembly 70 is used to push the second workpiece 202 so that the negative pressure detection member 62 detects the product 200 based on the negative pressure information of the receiving groove 611. For example, the clamping drive member 52 can be a cylinder, and the negative pressure detection member 62 can be a negative pressure detection gauge.

[0065] When the above-mentioned detection device 100 is actually used, the lifting component 30 first lifts the transmission component 20 to lift the product 200 transmitted by the transmission component 20, and the stop component 40 stops the product 200 to the detection position 11. Then the lifting component 30 drives the transmission component 20 to fall back, and the carrier 51 receives the fallen product 200 and carries the first workpiece 201. The clamping drive member 52 drives the linkage member 53 to drive the two clamping members 54 to move synchronously relative to each other to clamp the first workpiece 201 to the carrier 51, and then the pressing member 61 presses the first workpiece 201. 01 to the supporting member 51, the accommodating groove 611 covers the second workpiece 202 under the drive of the pressing member 61, and forms a negative pressure environment under the conduction of the external vacuum member, and finally the pushing component 70 pushes the second workpiece 202, and the negative pressure detection component 62 detects the product 200 based on the negative pressure information of the accommodating groove 611, and the lifting component 30 lifts the jacking transmission component 20 to enable the transmission component 20 to drive the transmission along the first direction after detection, thereby realizing rapid detection of the product 200 without stopping the transmission component 20, thereby improving the detection efficiency.

[0066] It can be understood that if the negative pressure detection part 62 detects that the negative pressure environment of the receiving groove 611 is released, it means that the first workpiece 201 and the second workpiece 202 are loosened from each other, and the atmosphere enters the receiving groove 611 through the mounting hole 2011, and it is determined that the product 200 fails the inspection. If the negative pressure detection part 62 detects that the negative pressure environment of the receiving groove 611 is stable and maintains a fixed negative pressure value, it means that the first workpiece 201 and the second workpiece 202 are stably bonded, and it is determined that the product 200 passes the inspection.

[0067] See also Figure 4 In some embodiments, the linkage member 53 includes a linkage body 531 and two rotating bodies 532. The linkage body 531 is disposed on a side of the support member 51 facing the frame 10 and is slidably connected to the support member 51 along the second direction. The linkage body 531 is connected to the clamping drive member 52. The two rotating bodies 532 correspond to the two clamping members 54 one by one and are respectively rotatably connected to the linkage body 531. One end of each rotating body 532 away from the linkage body 531 is rotatably connected to the corresponding clamping member 54. The two rotating bodies 532 are configured to tilt relative to the linkage body 531 under the drive of the linkage body 531, thereby driving the two clamping members 54 to move synchronously relative to each other or synchronously move away from each other.

[0068] In this way, by setting the specific structure of the above-mentioned linkage part 53, the linkage body 531 slides along the second direction under the drive of the clamping driving part 52, so that the two rotating bodies 532 are driven by the linkage body 531 to tilt relative to the linkage body 531, so as to drive the two clamping parts 54 to move synchronously relative to each other, thereby realizing the function of centering the first workpiece 201 along the first direction, ensuring that the first workpiece 201 and the second workpiece 202 are fixed to the detection position 11, so that the accommodating groove 611 can stably cover the second workpiece 202.

[0069] See also Figure 4 and Figure 7 In some embodiments, the clamping member 54 includes a connecting body 541, a protrusion 542, and a rolling body 543. The connecting body 541 is provided on a side of the supporting member 51 facing away from the pressing member 61 and is slidably connected to the supporting member 51 along a first direction. One end of the connecting body 541 is rotatably connected to the corresponding rotating body 532. The protrusion 542 is rotatably connected to the other end of the connecting body 541. The protrusions 542 of the two clamping members 54 are provided on opposite sides of the supporting member 51 along the first direction and extend out of the upper surface of the supporting member 51. The rolling body 543 is provided on a side of the protrusion 542 facing the pressing member 61 and is rotatably connected to the protrusion 542. The rolling body 543 is used to roll and abut the first workpiece 201 under the drive of the protrusion 542.

[0070] In this way, the connecting body 541 slides along the first direction driven by the rotating member, so that the protrusion 542 extending from the upper surface of the supporting member 51 drives the rolling body 543 to move close to the first workpiece 201, thereby realizing the function of clamping the workpiece along the first direction. At the same time, the rolling body 543 rolls and abuts the first workpiece 201, preventing the first workpiece 201 from being damaged during clamping.

[0071] Please continue reading Figure 4 and Figure 7 In some embodiments, the supporting member 51 includes a fixed body 512 and a supporting body 513. The fixed body 512 is provided at the detection position 11 and is connected to the frame 10. The fixed body 512 is provided with an avoidance hole 5121. The clamping drive member 52 and the pressing member 61 are both provided on the fixed body 512. The supporting body 513 is provided on a side of the fixed body 512 away from the frame 10 and has a plurality of supporting portions 5131. The plurality of supporting portions 5131 are spaced apart on a side of the supporting body 513 away from the fixed body 512 and are used to abut against the first workpiece 201 to support the first workpiece 201. The supporting body 513 is provided with an avoidance hole 5132. The avoidance hole 5132 is connected to the avoidance hole 5121 to form a through hole 511.

[0072] In this way, the fixed body 512 is connected to the pressing member 61 and the clamping drive member 52, so that the fixed body 512 supports the pressing member 61 and the clamping drive member 52, so that the layout of the detection device 100 is reasonable. In addition, the bearing portion 5131 is provided on the side of the bearing portion 513 away from the fixed body 512. When the transmission assembly 20 is in the process of falling back, the bearing portion 5131 supports the first workpiece 201 to carry the first workpiece 201. After falling back, the transmission assembly 20 is suspended on the upper surface of the bearing portion 513 and continues to operate, thereby realizing the detection of the product 200 without stopping the transmission assembly 20. At the same time, multiple bearing portions 5131 respectively abut against different positions of the first workpiece 201, thereby increasing the contact area between the bearing portion 51 and the first workpiece 201 and ensuring the bearing stability of the bearing portion 51. In addition, the avoidance hole 5121 of the fixing body 512 and the avoidance hole 5132 of the supporting body 513 are connected to form a through hole 511 to avoid the pushing assembly 70 and ensure that the pushing assembly 70 stably pushes the second workpiece 202.

[0073] See also Figure 7 In some embodiments, the clamping assembly 50 further includes a reference member 55 and a positioning member 56. The reference member 55 is disposed on a side of the fixed body 512 facing the pressing member 61. The positioning member 56 is protruding from a side of the linkage body 531 facing away from the frame 10 and corresponds to the reference member 55 along the second direction. The positioning member 56 is used to position the first workpiece 201 relative to the reference member 55 under the drive of the linkage body 531.

[0074] In this way, the positioning member 56 moves along the second direction close to the reference member 55 under the drive of the linkage body 531, so that the positioning member 56 and the reference member 55 position the first workpiece 201 along the second direction, thereby achieving the simultaneous positioning of the first workpiece 201 in the first direction and the second direction, ensuring that the first workpiece 201 remains in a stably placed state during the detection process, thereby improving the detection stability.

[0075] See also Figure 1 and Figure 8 In some embodiments, the stop assembly 40 includes a stop driver 41, a stopper 42, and a sensor 43. The stop driver 41 is spaced apart from the carrier 51 along a first direction and connected to the frame 10. The stopper 42 is connected to the stop driver 41. The stopper 42 is used to stop the product 200 being transported by the transport assembly 20 when driven by the stop driver 41. The sensor 43 is connected to the stop driver 42 and electrically connected to the stop driver 41. The sensor 43 is used to detect whether the product 200 has moved to the detection position 11. For example, the stop driver 41 may be a cylinder, and the sensor 43 may be a photoelectric sensor, a metal sensor, etc.

[0076] In this way, when the transmission component 20 drives the product 200 to move close to the detection position 11, the sensor 43 detects that the product 200 moves to the detection position 11 and sends an electrical signal to the stop drive 41. The stop drive 41 drives the stop member 42 to move away from the frame 10, so that the stop member 42 stops the product 200 to the detection position 11, thereby ensuring that the carrier 51 stably supports the product 200.

[0077] See also Figure 5 In some embodiments, the pressure member 61 includes a support frame 612, a pressure driving body 613, a support body 614, a holding body 615, and a pressure body 616. The support frame 612 is mounted on the carrier 513 and connected to the fixed body 512, and the pressure driving body 613 is disposed on the support frame 612. The support body 614 is disposed above the carrier 513 and connected to the pressure driving body 613. The support body 614 is used to move closer to or away from the carrier 513 along a third direction under the drive of the pressure driving body 613. The holding body 615 is disposed on a side of the support body 614 facing the carrier 513 and is connected to the support body 614. The holding body 615 is used to hold the first workpiece 201 against the carrier 513 under the drive of the support body 614. The pressing body 616 corresponds to the through hole 511 and is connected to the support body 614. The pressing body 616 is provided with a receiving groove 611. The pressing body 616 is used to press the first workpiece 201 and cover the second workpiece 202. For example, the pressing driving body 613 can be a cylinder.

[0078] In this way, by setting the specific structure of the above-mentioned pressing member 61, the pressing driving body 613 drives the support frame 612 to drive the supporting body 615 and the pressing body 616 to move synchronously close to the first workpiece 201, the supporting body 615 presses the first workpiece 201 to the carrier body 513 to position the workpiece along the third direction, and the pressing body 616 presses on the first workpiece 201 so that the receiving groove 611 covers the second workpiece 202, so as to facilitate the external vacuum part to perform vacuum operation on the receiving groove 611.

[0079] Please continue reading Figure 5 In some embodiments, the abutting body 615 includes a abutting portion 6151 and an elastic portion 6152. One end of the abutting portion 6151 is movably disposed through the support body 614 and is used to abut the first workpiece 201 toward the carrier 513. The other end of the abutting portion 6151 is used to abut the side of the support body 614 facing away from the carrier 513. The elastic portion 6152 is sleeved on the abutting portion 6151, and the two ends of the elastic portion 6152 elastically abut the side of the support body 614 facing the carrier 513 and the abutting portion 6151, respectively. Exemplarily, the elastic portion 6152 can be a spring.

[0080] In this way, when the supporting portion 6151 supports the first workpiece 201 to the carrier 513, the supporting portion 6151 compresses the elastic portion 6152 to the support body 614, so that the supporting portion 6151 flexibly supports the first workpiece 201 to prevent the first workpiece 201 from being damaged. When the supporting portion 6151 and the first workpiece 201 are loosened from each other, the compressed elastic portion 6152 elastically opens and resets, and drives the supporting portion 6151 to reset synchronously, so that the supporting member 61 can repeat the operation.

[0081] See also Figure 6 In some embodiments, the pressing member 61 further includes a sealing body 617, which is disposed around the receiving groove 611 and embedded in the side of the pressing member 616 facing the carrier 513. For example, the sealing body 617 can be a sealing ring.

[0082] In this way, by setting the above-mentioned sealing body 617, when the pressing body 616 moves close to the carrier 513, the sealing body 617 abuts against the first workpiece 201 to stably seal the accommodating groove 611, avoiding air leakage between the pressing body 616 and the first workpiece 201 and destroying the negative pressure environment of the accommodating groove 611.

[0083] See also Figure 1 and Figure 9In some embodiments, the transmission assembly 20 includes two parallel transmission members 21, and the lifting assembly 30 includes a lifting drive member 31, a lifting member 32, and two rotating members 33. The lifting drive member 31 is disposed below the transmission member 21 and connected to the frame 10. The lifting member 32 is connected to the lifting drive member 31 and is configured to move toward or away from the frame 10 under the drive of the lifting drive member 31. The two rotating members 33 correspond one-to-one with the two transmission members 21 and are rotatably connected to the ends of the lifting member 32. Each rotating member 33 is provided with an annular groove 331, which is arranged along the circumference of the rotating member 33 and accommodates the corresponding transmission member 21. The two rotating members 33 are configured to lift the two transmission members 21 under the drive of the lifting member 32. By way of example, the transmission member 21 may be a conveyor belt, and the lifting drive member 31 may be a cylinder.

[0084] In this manner, by accommodating the corresponding transmission member 21 through the annular groove 331, the lifting drive member 31 drives the lifting member 32 to cause the two rotating members 33 to move synchronously away from or toward the frame 10, so that the two rotating members 33 lift the two transmission members 21 or return the two transmission members 21 to their initial positions, thereby achieving the lifting and lowering operation of the transmission member 21. In addition, by providing a rotational connection between the rotating member 33 and the lifting member 32, the transmission member 21 can slide within the annular groove 331 when being lifted or lowered, thereby ensuring that the transmission member 21 always maintains a normal operating state.

[0085] See also Figure 1 In this embodiment, there are two sets of lifting assemblies 30, which are spaced apart along the first direction, with the carrier 513 and the stopper assembly 40 located between the two sets of lifting assemblies 30. Thus, by providing two sets of lifting assemblies 30, the transmission member 21 can be parallel to the upper surface of the carrier 513 when it is lifted to a predetermined height, thus preventing the transmission member 21 from tilting, which could cause the product 200 to tilt and collide with other components.

[0086] See also Figure 3 、 Figure 10 and Figure 11In some embodiments, the push assembly 70 includes a push drive member 71, a loading member 72, an elastic member 73, a limiting member 74, and a push member 75. The push drive member 71 is disposed below the support member 51 and connected to the frame 10. The loading member 72 is connected to the push drive member 71 and is provided with a seating groove 721 and a limiting groove 722. The seating groove 721 is spaced away from the push drive member 71 relative to the limiting groove 722, and the limiting groove 722 is formed at the bottom of the seating groove 721 adjacent to the push drive member 71. The elastic member 73 is disposed in the seating groove 721. One end of the limiting member 74 is movably inserted into the elastic member 73, and the other end of the limiting member 74 is configured to abut against the bottom of the limiting groove 722. The push member 75 is detachably connected to the limiting member 74 and abuts against an end of the elastic member 73 away from the push-driving member 71. The push member 75 extends out of the receiving groove 721 and is movably inserted into the through hole 511. The push member 75 is used to push the second workpiece 202 under the drive of the push-driving member 71. For example, the push-driving member 71 can be a cylinder, and the elastic member 73 can be a spring.

[0087] In this way, the loading part 72 is driven by the pushing driving part 71 to drive the pushing part 75 to move close to the second workpiece 202. The pushing part 75 is subjected to the reaction force of the second workpiece 202 to compress the elastic part 73 to the bottom of the installation groove, so that the elastic part 73 offsets part of the thrust applied by the pushing driving part 71, so that the pushing part 75 can flexibly push the second workpiece 202 to avoid damage to the second workpiece 202. When the pushing part 75 and the second workpiece 202 are loosened from each other, the compressed elastic part 73 elastically opens and resets and drives the pushing part 75 to drive the limiting part 74 to reset. The limiting part 74 abuts against the bottom of the limiting groove 722 to limit the movement distance of the pushing part 75 and prevent the pushing part 75 from separating from the loading part 72. In addition, since the driving force of the push-pull driving member 71 is a fixed value and the length to which the elastic member 73 can be compressed is limited, by setting the push-pull member 75 and the limiting member 74 to be detachably connected, the length of the push-pull member 75 extending to the mounting groove 721 is adjusted or the elastic member 73 with a different elastic coefficient is replaced to control the push-pull member 75 to compress the elastic member 73 to a preset length when in the initial position, thereby controlling the length value of the elastic member 73 compressed by the push-pull member 75 when pushing the second workpiece 202, so as to control the size of the inference value that the elastic member 73 can offset, and then control the push force applied to the second workpiece 202 by the push-pull member 75, thereby ensuring that the push-pull member 75 applies a preset thrust to the second workpiece 202 according to different detection requirements, and avoiding the replacement of the push-pull driving member 71 with different thrusts.

[0088] The working process of the above-mentioned detection device 100 is roughly as follows:

[0089] First, the two rotating members 33 receive the corresponding transmission members 21 through the annular grooves 331, and the lifting member 31 drives the lifting member 32 to move the two rotating members 33 away from the frame 10, so that the two rotating members 33 lift the two transmission members 21 at the initial height to a preset height, so that the two transmission members 21 lifted to the preset height transport the products 200 along the first direction;

[0090] Next, when the transmission assembly 20 drives the product 200 to move toward the detection position 11, the sensor 43 detects that the product 200 has moved to the detection position 11 and sends an electrical signal to the stop driver 41. The stop driver 41 drives the stop driver 42 to move away from the frame 10, so that the stop driver 42 stops the product 200 at the detection position 11. The lifting driver 31 drives the two rotating members 33 to drive the two transmission members 21 back to the initial height, so that the carrier 513 receives the product 200 and carries the first workpiece 201.

[0091] Then, the clamping drive member 52 drives the linkage member 53 to drive the two clamping members 54 to move synchronously relative to each other, so as to clamp the first workpiece 201 to the carrier 51 along the first direction. At the same time, the positioning member 56, driven by the linkage member 53, clamps the first workpiece 201 to the reference member 55 along the second direction. The pressing member 61 presses the first workpiece 201 to the carrier 51. The accommodating groove 611, driven by the pressing member 61, covers the second workpiece 202, and forms a negative pressure environment under the conduction of the external vacuum member.

[0092] Finally, the push driving member 71 drives the push member 75 to move close to the second workpiece 202 and push the second workpiece 202. The negative pressure detection member 62 detects the product 200 based on the negative pressure information of the accommodating groove 611. After the product 200 completes the detection, the lifting driving member 31 drives the two rotating members 33 to lift the two transmission members 21 to a preset height, so that the two transmission members 21 drive the continued transmission along the first direction after detection, thereby realizing rapid detection of the product 200 without stopping the transmission member 21, thereby improving the detection efficiency.

[0093] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
