It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] In order to solve the technical problem that the medicine box defect detection equipment in the prior art lacks a structure for assisting the medicine box flipping, when the medicine box falls from the upper conveyor belt to the lower conveyor belt, the medicine box is prone to fail to flip in time, resulting in certain parts of the medicine box being unable to be detected, and defective products will be shipped out of the factory, the utility model provides an aluminum pharmaceutical packaging production line defect detection device, which can realize the flipping of the medicine box so that all sides of the medicine box can be photographed and inspected, and basically no defective medicine boxes will appear when leaving the factory.

[0026] It should be noted that the aluminum pharmaceutical packaging production line defect detection device described in the present invention is used for but not limited to detecting the appearance of medicine boxes, etc. For the convenience of explanation, in the present invention, only the application of the aluminum pharmaceutical packaging production line defect detection device to detecting the appearance of medicine boxes is used as an example for explanation. The principle of applying the aluminum pharmaceutical packaging production line defect detection device to other types of equipment is essentially the same as the principle of applying it to detecting the appearance of medicine boxes, and they will not be described one by one here.

[0027] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of the aluminum pharmaceutical packaging production line defect detection device in one embodiment of the present invention. The aluminum pharmaceutical packaging production line defect detection device includes a conveying component, a detection component and a flip guide component. The conveying component includes a first conveyor line 1 and a second conveyor line 2 spaced apart from each other. The first conveyor line 1 and the second conveyor line 2 are both composed of a conveyor belt and a plurality of rollers, one of which is connected to a motor (not shown in the figure) through a transmission belt 3. When the motor is working, it can drive the conveyor belt to move through the transmission belt 3 to drive the medicine box on the conveyor belt to move. The first conveyor line 1 is used to drive the medicine box 3 toward Figure 1 The second conveyor line 2 is used to drive the medicine box 3 toward the right side of the Figure 1 In the left-side movement shown, the movement directions of the first conveyor line 1 and the second conveyor line 2 are opposite.

[0028] The detection assembly includes a first detection member and a second detection member, which are respectively located on the first conveyor line 1 and the second conveyor line 2. The first detection member is used to detect the medicine boxes 3 located on the first conveyor line 1, and the second conveyor line 2 is used to detect the medicine boxes located on the second conveyor line 2. The first detection member and the second detection member detect inconsistent parts of the medicine boxes. Through the comprehensive detection of the first detection member and the second detection member, the medicine boxes 3 are fully inspected.

[0029] See also Figure 2 The flip guide assembly includes an auxiliary flip part 4, which is located between the output end of the first conveyor line 1 and the input end of the second conveyor line 2, so that the medicine box 3 falling from the first conveyor line 1 can pass through the auxiliary flip part 4. The auxiliary flip part 4 has an arc-shaped guide surface 44. The medicine box 3 will automatically flip over due to its own gravity in the process of falling into the auxiliary flip part 4. The medicine box 3 will then slide along the arc-shaped guide surface 44 to the second conveyor line 2, and then move along the second conveyor line 2 to the second detection part to be detected by the second detection part.

[0030] In one embodiment, see Figure 2 The auxiliary flip member 4 includes a first section 41, a second section 42 and a third section 43 connected in sequence. The first section 41 is vertically arranged and close to the outlet end of the first conveyor line 1. The second section 42 is arc-shaped. The third section 43 is straight and arranged at an angle to the second conveyor line 42. The outlet end of the third section 43 is close to the second conveyor line 2. In this embodiment, the first section 41, the second section 42 and the third section 43 are an integrally formed structure, so that the first section 41, the second section 42 and the third section 43 are stably connected and the connection is smooth, which does not affect the downward movement of the medicine box 3. The first section 41 is set to a vertical shape, which can limit the medicine box 3 to prevent the medicine box 3 from flying away when entering the auxiliary flip member 4. The second section 42 is set to an arc shape, which is conducive to the smooth sliding of the medicine box 3. The third section 43 is inclined, and its outlet end is close to the second conveyor line 2, which is conducive to the medicine box 3 being able to slide into the second conveyor line 2 along the third section 43.

[0031] In one embodiment, see Figure 2 The flip guide assembly also includes a support rod 5 and a sliding rod 6. The sliding rod 6 is inserted into the support rod 5 for sliding in the vertical direction. The top of the sliding rod 6 is connected to the auxiliary flip part 4 and can adjust the height of the auxiliary flip part 4 when sliding so that the auxiliary flip part 4 is at a suitable height, which can not only limit the medicine box 3 from flying out, but also guide the medicine box 3.

[0032] In one embodiment, see Figure 2The flip guide assembly further includes a locking mechanism disposed on the support rod 5. The locking mechanism comprises a locking member 7 and a spring 8. The slide rod 6 defines a plurality of slots 61 spaced apart along its length. The locking member 7 is horizontally slidably inserted into the support rod 5 to engage or disengage with the slots 61. The spring 8 connects the support rod 5 and the locking member 7. The spring 8 is capable of elastically driving the locking member 7 to engage with the slots 61 and is capable of being stretched to accumulate elastic force when the locking member 7 is disengaged from the slots 61. In this embodiment, when the height of the auxiliary flip member 4 needs to be adjusted, the locking member 7 can be first moved away from the slide rod 6 to disengage from the slots 61 of the slide rod 6. During this process, the spring 8 is stretched, accumulating elastic force, and the slide rod 6 is now unlocked. The slide rod 6 is then slid up and down relative to the support rod 5 to a target position. The locking member 7 is then released. The spring 8 releases its elastic force, driving the locking member 7 to slide and engage with a new slot 61, thereby securing the slide rod 6. In this embodiment, the height of the auxiliary flip member 4 can be adjusted and fixed only by the cooperation of the locking member 7 and the spring 8, which is convenient to use.

[0033] In one embodiment, see Figure 1 The conveying assembly further includes a storage platform 9, on which both the first conveyor line 1 and the second conveyor line 2 are disposed. The support rod 5 is slidably connected to the storage platform 9 to move closer to or further away from the first conveyor line 1. In this embodiment, the support rod 5 is slidably connected to the storage platform 9 in a horizontal direction, so that the support rod 5 can slide back and forth in the horizontal direction to change the horizontal position of the auxiliary flip member 4. The auxiliary flip member 4 can move closer to or further away from the first conveyor line 1 or the second conveyor line 2, allowing the medicine box 3 to stably flip and fall into the auxiliary flip member 4.

[0034] In one embodiment, see Figure 1 and Figure 2 The storage platform 9 has a horizontally extending slideway (not shown), into which the bottom of the support rod 5 is slidably engaged, enabling the support rod 5 to slide back and forth horizontally. The conveying assembly also includes a screw 10, which is threaded through the support rod 5 and rotates in place to connect to the storage platform 9, driving the support rod 5 to slide back and forth as it rotates. In this embodiment, the screw 10 drives the support rod 5 and the auxiliary flip member 4 to reciprocate, allowing for more precise adjustment of the position of the auxiliary flip member 4.

[0035] In one embodiment, see Figure 1The first detection part includes a bracket 11 and a first camera 12, a second camera 13 and a third camera 14 arranged on the bracket 11. Specifically, the first camera 12 is arranged on the top of the bracket 11, and the second camera 13 and the third camera 14 are respectively arranged on the front and back sides of the bracket 11. The first detection part also includes a fourth camera 15 arranged on the support rod 5. The fourth camera 15 is used to shoot the side of the medicine box 3 after it is flipped. When the medicine box 3 is flipped, the left side of the medicine box 3 faces the fourth camera 15, so the fourth camera 15 is used to shoot the left side of the medicine box 3. The first camera 12 is used to shoot the top side of the medicine box on the first conveyor line 11, and the second camera 13 and the third camera 14 are used to shoot the front and back sides of the medicine box 3. The medicine box 3 of this application is limited to a rectangular shape. The medicine box 3 has a total of six faces. The above four cameras can shoot and detect four of the faces of the medicine box 3.

[0036] In one embodiment, the conveying assembly further includes a buffer mechanism, the inlet and outlet ends of which are respectively close to the outlet end of the first conveyor line 11 and the inlet end of the auxiliary flip member 4. Since the conveying speed of the first conveyor line 11 is relatively fast, the buffer mechanism of this embodiment is used to buffer the medicine boxes 3 conveyed by the first conveyor line 11 to prevent the medicine boxes 3 from colliding with the auxiliary flip member 4 due to their large inertia and causing damage to the medicine boxes 4.

[0037] See also Figure 3 Furthermore, the buffer mechanism includes a gantry 16 and a buffer tray provided on the gantry 16, the buffer tray includes a frame 17 and a plurality of buffer rollers 18, the frame 17 is connected to the gantry 16, and the plurality of buffer rollers 18 are arranged on the frame 17 in parallel and rotated at intervals. The medicine box 3 on the first conveyor line 11 is pushed to the buffer tray by inertia and continues to move forward along the plurality of buffer rollers 18 until one end of the medicine box 3 exceeds the edge of the frame 17. When the center of gravity of the medicine box 3 exceeds the edge of the frame 17, the medicine box 3 can flip over, with one side first contacting the auxiliary flip part 4, and then sliding along the auxiliary flip part 4 to the second conveyor line 2. It should be emphasized that the distance between the edge of the frame 17 and the auxiliary flip part 4 needs to be controlled so that the medicine box 3 can just slide down along the auxiliary flip part 4 to the second conveyor line 2 after flipping once.

[0038] In one embodiment, see Figure 1 The detection assembly further includes a fifth camera 19 disposed on the gantry 16. The fifth camera 19 is used to photograph the right side of the medicine box 3. When the medicine box 3 moves on the first conveyor line 1, the right side of the medicine box 3 faces the fifth camera 19, so the fifth camera 19 can photograph the right side of the medicine box 3.

[0039] In addition, the second detection part includes a sixth camera 20. The second camera 20 is arranged above the second conveyor line 2 and is used to photograph and detect the medicine box 3 on the second conveyor line 2. When the medicine box 3 slides along the auxiliary flip part 4 to the second conveyor line 2, the medicine box 3 moves to the left under the drive of the second conveyor line 2. At this time, the medicine box 3 has been flipped, so the bottom of the medicine box 3 faces up and the bottom faces down. When the medicine box 3 moves to the bottom of the sixth camera 20, the sixth camera 20 can photograph and detect the bottom of the medicine box 3, thereby completing the all-round shooting and detection of the medicine box 3, and there is no blind spot in the detection of the medicine box 3.

[0040] In one embodiment, see Figure 1 The detection device also includes a blowing piece 21, which is arranged near the outlet end of the second conveyor line 2. All cameras and the blowing piece 21 are connected to the same control system. When any of the above cameras detects that one side of the medicine box 3 is unqualified, the control system will control the blowing piece 21 to blow out the medicine box 3 to prevent the medicine box 3 from entering the qualified area.

[0041] In one embodiment, see Figure 1 The detection device also includes a display screen 22. When the medicine box 3 detected by the camera is unqualified, the display screen 22 can display the unqualified side for the staff to view.

[0042] In order to better understand the present invention, the following Figures 1 to 3 The technical solution of the utility model is described in detail:

[0043] The aluminum pharmaceutical packaging production line defect detection device provided by the present invention comprises a first conveyor line 1 and a second conveyor line 2, both of which are capable of conveying medicine boxes 3. The first detection component includes a first camera 12, a second camera 13, a third camera 14, and a fourth camera 15, which are capable of photographing and inspecting the top side, front side, back side, and left side of the medicine box 3, respectively. The fifth camera 19 is capable of photographing and inspecting the right side of the medicine box 3. The sixth camera 20 included in the second detection component is capable of photographing and inspecting the bottom surface of the medicine box 3 after the medicine box 3 is flipped by the auxiliary flipping component 4, so that all directions of the medicine box can be photographed and inspected, and there is basically no possibility of defective medicine boxes when leaving the factory.
