Technical Field
[0001] The present application relates to the technical field of workpiece detection equipment, and in particular to a workpiece multi-surface detection equipment. Background Art
[0002] After the blank printed circuit board is processed by SMT patch, welding and other processes, various types of raised structures with specific directions can be formed on the printed circuit board. This type of printed circuit board with raised structures on the surface can be called a workpiece. Before the next step of fine processing, the workpiece needs to be inspected for scratches, pressure injuries, and contamination on its surface by optical inspection equipment to eliminate defective workpieces that do not meet the requirements of fine processing.
[0003] Most existing optical inspection equipment includes a camera fixed at a high place, a conveyor belt that runs continuously in a specific direction under the camera, and an automatic graphic comparison and analysis structure that is electrically connected to the camera and the conveyor belt and can analyze the photos taken by the camera. The workpiece to be inspected is placed on the conveyor belt. As the conveyor belt continues to run, when the workpiece passes under the camera, the camera can quickly take a front photo of the workpiece. The photo taken by the camera can be acquired by the automatic graphic comparison and analysis structure and compared with the standard workpiece photos in its database. If the surface of the workpiece is not damaged, contaminated or otherwise affects the next step of finishing, the conveyor belt continues to transport other workpieces to be inspected; if the surface of the workpiece is damaged, contaminated or otherwise affects the workpiece to enter the next step of finishing, the conveyor belt can stop to remind the operator that there is a problem with the workpiece currently being transported.
[0004] However, this type of optical inspection equipment can only inspect the front side of the workpiece in transit, while the back side of the workpiece also has various types of raised structures with specific directions, which also need to be inspected; even some workpieces with special uses also need to be inspected on the side of the workpiece; therefore, when the front, back and side of the workpiece need to be inspected, a workpiece must be put on the conveyor belt at least three times, and each time the operator needs to turn the workpiece to be inspected upwards, and when the side of the workpiece is facing upwards, it may be necessary to use external objects to complete the positioning; this makes the optical inspection equipment cumbersome, inconvenient and inefficient when performing multi-sided inspection of workpieces, which needs to be improved. Summary of the invention

[0025] The embodiment of the present application discloses a workpiece multi-surface detection device.
[0026] The following is combined with Figure 1-5 This application is described in further detail.
[0027] Reference Figure 1 A multi-faceted workpiece inspection device includes an operating table 1. In this embodiment, the operating table 1 can be a rectangular steel box with an electric control device inside and a horizontal top wall.

[0028] Reference Figure 2 A conveyor frame 11 is installed on the top wall of the operating table 1 along the first direction X. The conveyor frame 11 can be a belt conveyor, and the conveyor frame 11 is used to place the workpiece to be inspected.
[0029] Reference Figure 2 In order to inspect the workpieces transported on the conveyor 11, the workpiece multi-faceted inspection device further includes at least two groups of searchlight mechanisms 2. In this embodiment, the number of the searchlight mechanisms 2 can be two groups, and the two groups of searchlight mechanisms 2 are both located on the same side of the width direction of the conveyor 11; taking one group of searchlight mechanisms 2 as an example, the searchlight mechanism 2 includes a bracket 3 and a camera assembly 4.
[0030] Reference Figure 2The bracket 3 can be a rectangular steel column, and the bracket 3 is vertically welded to the top wall of the operating table 1.
[0031] Reference Figure 2 The camera assembly 4 includes a transverse linear motor 41, a shadowless spotlight 42 and a camera probe 43; wherein the transverse linear motor 41 is welded to the bracket 3 along the second direction Y, the two are L-shaped, and the end of the transverse linear motor 41 away from the bracket 3 can pass through the top of the conveying rack 11.
[0032] Reference Figure 2 and Figure 3 The shadowless spotlight 42 is fixed to the moving end of the horizontal linear motor 41 by bolts, and the shadowless spotlight 42 is installed along the third direction Z, with its light source facing the conveying rack 11 to provide illumination for the workpiece on the conveying rack 11.
[0033] Reference Figure 2 and Figure 3 The camera probe 43 can be an ultra-high-definition camera connected to an automatic graphic comparison and analysis structure. The camera probe 43 passes through the shadowless spotlight 42 along the third direction Z and is glued and fixed on the shadowless spotlight 42. When the conveyor frame 11 transports the workpiece under the shadowless spotlight 42, the conveyor frame 11 pauses for 2-5 seconds, and the specific time can be adjusted by the operator according to needs. During this period, the shadowless spotlight 42 provides light to the workpiece, which facilitates the camera probe 43 to take an intuitive and shadow-free photo of the front of the workpiece. The photos taken by the camera probe 43 can be automatically uploaded to the cloud, and the photos taken can be compared with the photos of qualified workpieces on the cloud through the automatic graphic comparison and analysis structure to determine whether there is damage, contamination or other problems on the surface of the workpiece that affect the workpiece from entering the next step of fine processing.
[0034] Reference Figure 2 When the conveyor frame 11 transports workpieces of different outer circumferential sizes, the moving end of the transverse linear motor 41 can move along the first direction X to drive the shadowless spotlight 42 and the camera probe 43 to move to a position where the workpiece can be fully and clearly photographed.
[0035] Reference Figure 3 In order to reduce the problem of interference of dust or other impurities in the air on the shooting of the camera probe 43, a plurality of guide fans 421 are arranged on the side wall of the shadowless spotlight 42. The guide fans 421 can be fans with their own rechargeable power supply. The plurality of guide fans 421 are evenly and spacedly distributed along the circumference of the shadowless spotlight 42, and each guide fan 421 is arranged along the third direction Z, with the air outlet of the guide fan 421 pointing vertically downward; each guide fan 421 is detachably fixed on the side wall of the shadowless spotlight 42 by magnetic attraction of positive and negative magnets.
[0036] Reference Figure 3In this embodiment, the multiple guide fans 421 blow air downward along the third direction Z to reduce the problem of a large number of floating objects and impurities in the irradiation range of the shadowless spotlight 42, and reduce the pollution to the camera probe 43. In addition, in actual use, the guide fans 421 speed up the airflow velocity around the shadowless spotlight 42, which helps to reduce the ambient temperature around the shadowless spotlight 42, thereby reducing the problem of unstable illumination of the shadowless spotlight 42 due to long-term high-temperature application.
[0037] Reference Figure 4 In order to enable the camera probe 43 to take pictures of the back side and even the side of the workpiece, the workpiece multi-side detection equipment also includes at least two groups of positioning mechanisms 5; in this embodiment, the number of positioning mechanisms 5 can be two groups, and the two groups of positioning mechanisms 5 are on the operating table 1 and located on the side of the conveying rack 11 away from the bracket 3. One group of positioning mechanisms 5 can correspond to one group of brackets 3.
[0038] Reference Figure 4 In this embodiment, the multi-faceted workpiece inspection device further includes a transverse linear motor 2 6 for assisting the two sets of positioning mechanisms 5 to be installed on the operating table 1. The transverse linear motor 2 6 is fixed to the top wall of the operating table 1 along the first direction X by bolts, and the transverse linear motor 2 6 is parallel to the conveyor frame 11. In addition, the transverse linear motor 2 6 can be a linear motor with two moving ends, and the two moving ends of the transverse linear motor 2 6 can approach or move away from each other along the first direction X, or one of the moving ends remains stationary and the other moves along the first direction X.
[0039] Reference Figure 4 , taking a set of positioning mechanism 5 as an example, the positioning mechanism 5 includes a vertical linear motor 7, a flip motor 8 and a negative pressure adsorption component 9; it should be noted that in this embodiment, the two vertical linear motors 7 of the two sets of positioning mechanism 5 are respectively fixed to the two moving ends of the horizontal linear motor 2 6 by bolts. A set of vertical linear motors 7 corresponds to a set of brackets 3, and the horizontal linear motor 2 6 can move along the first direction X through the moving end, so that the vertical linear motor 7 can be moved and adjusted relative to the conveying rack 11.
[0040] Reference Figure 4 and Figure 5 The flip motor 8 is fixed to the moving end of the vertical linear motor 7 along the second direction Y by bolts, the output end of the flip motor 8 is close to the conveying rack 11, and the moving end of the vertical linear motor 7 can carry the flip motor 8 to move along the third direction Z to adjust the distance between the flip motor 8 and the operating table 1.
[0041] Reference Figure 4 and Figure 5The negative pressure adsorption component 9 is arranged on the output end of the flip motor 8, and the negative pressure adsorption component 9 includes an abutment plate 91, a negative pressure suction nozzle 92 and an air pipe 93; wherein, the abutment plate 91 is arranged on the output end of the flip motor 8 through the connecting component 10. In the present embodiment, the abutment plate 91 can be a rectangular solid steel block, and the abutment plate 91 is located above the conveying rack 11.
[0042] Reference Figure 4 and Figure 5 One end of the air pipe 93 in the length direction is connected to an air source, which can be a negative pressure suction pump, and the air source is installed on the operating table 1. The other end of the air pipe 93 in the length direction is connected to the abutment plate 91, and a channel that can be connected to the air pipe 93 is provided on the abutment plate 91. The negative pressure suction nozzle 92 is glued to the side wall of one side of the abutment plate 91 in the width direction, and the negative pressure suction nozzle 92 is connected to the air pipe 93.
[0043] Reference Figure 4 and Figure 5 When the camera probe 43 takes a picture of the front of the workpiece, the abutment plate 91 is located on the side of the workpiece being inspected. When the camera probe 43 completes taking pictures, the moving end of the horizontal linear motor 26 can carry the vertical linear motor 7, the flip motor 8 and the abutment plate 91 to move directly below the camera probe 43. Then, the moving end of the vertical linear motor 7 moves downward, so that the flip motor 8 carries the abutment plate 91 and moves downward along the third direction Z until the side wall of the abutment plate 91 with the negative pressure suction nozzle 92 abuts against the workpiece.
[0044] Reference Figure 4 and Figure 5 , the air source sucks the air at the negative pressure suction nozzle 92 through the air pipe 93, and the negative pressure suction nozzle 92 negatively absorbs the workpiece, so that the workpiece can be tightly adsorbed on the side wall of the abutment plate 91 on which the negative pressure suction nozzle 92 is installed. The moving end of the vertical linear motor 7 moves upward along the third direction Z again, so that the abutment plate 91 moves the workpiece toward the direction close to the camera probe 43 through the negative pressure suction nozzle 92 until it is located above the conveying rack 11. The flip motor 8 rotates the output end, so that the abutment plate 91 can carry the workpiece and rotate along the circumferential direction of the output end of the flip motor 8, thereby exposing the back or side of the workpiece to the shadowless spotlight 42, so that the camera probe 43 can shoot the front, back, or side of the workpiece. Furthermore, since two groups of searchlight mechanisms 2 and positioning mechanisms 5 are provided, the multi-sided workpiece detection equipment can detect at least two groups of workpieces on a conveyor rack 11 at the same time. While the multi-sided workpiece detection equipment can detect multiple surfaces of the workpiece, the efficiency of the multi-sided workpiece detection equipment in detecting workpieces is further improved by increasing the number of workpieces that can be detected at a single time by the multi-sided workpiece detection equipment.
[0045] Reference Figure 5The connection assembly 10 is used to ensure the connection strength of the abutment plate 91 installed on the output end of the flip motor 8 and the stability of the abutment plate 91 in subsequent applications. The connection assembly 10 includes a fixed enclosure 101, multiple reinforcement members 102 and a locking unit 103; the fixed enclosure 101 can be a rectangular solid steel plate, and the fixed enclosure 101 is passed through the output end of the flip motor 8 and then welded to the output end of the flip motor 8.
[0046] Reference Figure 5 A reinforcement 102 is vertically welded to the side wall of the fixed enclosure 101 along the second direction Y, and all reinforcements 102 are evenly and spacedly distributed along the circumference of the output end of the flip motor 8, and the extension direction of the reinforcement 102 is the same as the axial direction of the output end of the flip motor 8.
[0047] Reference Figure 5 In this embodiment, each reinforcing member 102 further includes a fixed square column 1021, an outer sleeve 1022 and a locking bolt 1023. One end of the fixed square column 1021 in the length direction is directly welded to the side wall of the fixed enclosure 101, and the length dimension of the output end of the flip motor 8 is smaller than the length dimension of the fixed square column 1021. The outer sleeve 1022 can be a square cylinder whose inner diameter dimension is adapted to the outer diameter dimension of the fixed square column 1021. The outer sleeve 1022 is sleeved on the other end of the fixed square column 1021 in the length direction, and the outer sleeve 1022 can move along the axial direction of the fixed square column 1021. When the outer sleeve 1022 moves on the fixed square column 1021 and determines the position, the locking bolt 1023 can pass through the outer sleeve 1022 and be screwed into the preset thread groove on the fixed square column 1021, so that the outer sleeve 1022 is fixed on the fixed square column 1021.
[0048] Reference Figure 5 The abutment plate 91 is fixedly connected to all the reinforcement members 102 through the locking unit 103, wherein the locking unit 103 includes a top arc-abutting plate 1031 and a plurality of connecting bolts 1032. The abutment plate 91 is tightly abutted and welded to the side wall of all the outer sleeves 1022 located below the output end of the flip motor 8, and the top arc-abutting plate 1031 passes through all other reinforcement members 102 to achieve sleeve connection on the reinforcement members 102. In addition, both ends of the top arc-abutting plate 1031 in the length direction are abutted and welded to the abutment plate 91 and the reinforcement members 102 abutting against the abutment plate 90.
[0049] Reference Figure 5 At this time, the abutment plate 91 and the top arc plate 1031 can wrap all the reinforcement members 102 from top to bottom along the third direction Z. The connecting bolts 1032 can be threaded on the side wall of the outer sleeve 1022 after passing through the top arc plate 1031 to strengthen the connection strength between the top arc plate 1031 and the reinforcement member 102, which helps to ensure the connection strength of the abutment plate 91 installed on the outer sleeve 1022.
[0050] The implementation principle of a workpiece multi-faceted inspection device according to an embodiment of the present application is as follows: when the conveyor frame 11 transports the workpiece to under the shadowless spotlight 42 , the conveyor frame 11 stops running. At this time, two groups of workpieces are under two groups of shadowless spotlights 42 .
[0051] At least one group of workpieces is photographed from the front; the shadowless spotlight 42 provides illumination for the workpiece, so that the camera probe 43 can take intuitive, shadow-free photos of the front of the workpiece. The photos taken by the camera probe 43 can be automatically uploaded to the cloud, and the photos taken can be compared with the photos of qualified workpieces on the cloud through the automatic graphic comparison and analysis structure to determine whether the workpiece surface is damaged, contaminated, or has other problems that affect the workpiece from entering the next step of fine processing.
[0052] When one group of workpieces is photographed from the front, the air pipe 93 can suck the gap at the negative pressure suction nozzle through the air source, so that the abutment plate 91 sucks the workpiece through the negative pressure suction nozzle 92. The moving end of the vertical linear motor 7 carries the flip motor 8 and the workpiece to move upward along the third direction Z, so that the workpiece moves to the top of the conveyor rack 11. The flip output end of the flip motor 8 can expose the back or side of the workpiece to the shadowless spotlight 42, so that the camera probe 43 can take pictures of the front, back, or side of the workpiece, so as to improve the efficiency of the workpiece multi-faceted detection equipment in detecting workpieces.
[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
