Description

Technical Field

[0001] The utility model relates to the field of detection technology, in particular to a whole board device and detection equipment. Background Art

[0002] In AOI optical inspection lines, the products typically inspected are printed circuit boards (PCBs). Due to factors such as the PCB's own weight and the processing technique, the PCB will deform to a certain extent when placed on the inspection equipment's track.

[0050] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them.

In this specification, schematic representations of these terms do not necessarily refer to the same embodiment or example.

[0055] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0056] Unless specifically stated or defined otherwise, the term “and / or” used in the present invention includes any and all combinations of one or more of the associated listed items.

[0057] For the convenience of description, unless otherwise specified, the up and down directions mentioned below are the same as Figure 1 The up and down directions are consistent.

[0058] In the related art, when performing AIO optical inspection on a circuit board, the circuit board is generally placed on two spaced-apart tracks of the inspection equipment. Due to the relatively small thickness of the circuit board and the low overall rigidity, especially when the circuit board is relatively large and thin, in the absence of a fixture, the circuit board will be deformed to a certain extent when placed on the track. When the deformation exceeds the depth of field of the camera, the image captured by the camera will be unclear, resulting in inspection failure. Existing inspection equipment generally has a pin to lift and correct downward-concave circuit boards, but it cannot be used for upward-convex circuit boards. The upward-convex circuit boards cannot be adjusted, which seriously affects the efficiency of circuit board inspection and the accuracy of the inspection results.

[0059] In order to solve the problem in the related art that it is impossible to correct the upwardly protruding circuit board, the present application provides a whole-board device 1, which can adjust the flatness of the downwardly concave circuit board and the upwardly protruding circuit board, so as to facilitate the camera of the detection equipment to perform shooting and detection, improve the applicability of the detection equipment, avoid the detection equipment from having inaccurate detection results or detection failures of the circuit board due to unclear photographed images, and improve the efficiency and accuracy of circuit board detection.

[0060] like Figures 1 to 7As shown, the whole plate device 1 provided in the present application includes a base 11, a lifting seat 12, an adsorption member 13, a lifting member 14, and a driver 15. The lifting seat 12 is arranged above the base 11, and the lifting seat 12 can be movably arranged relative to the base 11. The adsorption member 13 and the lifting member 14 can be detachably installed on the upper surface of the lifting seat 12, and the adsorption member 13 and the lifting member 14 are arranged at intervals on the lifting seat 12. The driver 15 connects the base 11 and the lifting seat 12 to drive the lifting seat 12 to move closer to or away from the base 11. The driver 15 can drive the lifting seat 12 to move up and down relative to the base 11, so that the lifting seat 12 switches between an ascending position and a descending position, thereby driving the adsorption member 13 and the lifting member 14 to move up and down.

[0061] During the process of placing the circuit board on the track for photo inspection, when the circuit board is concave, the whole board device 1 is installed on the inspection equipment so that the whole board device 1 is located below the track and the lifting member 14 is located below the concave area on the circuit board, and then the driver 15 can be used to drive the lifting seat 12 to move upward relative to the base 11, and the lifting member 14 pushes upward against the concave area on the circuit board, causing the concave area on the circuit board to deform upward, thereby adjusting the flatness of the circuit board. When the circuit board is convex upward, the whole board device 1 is installed on the inspection equipment so that the whole board device 1 is located below the track and the suction member 13 is located below the concave area on the circuit board, and then the driver 15 can be used to drive the lifting seat 12 to move upward relative to the base 11, and the suction member 13 sucks the concave area on the circuit board upward, and then the driver 15 drives the lifting seat 12 to move downward, so that the suction member 13 can pull the concave area on the circuit board downward, causing the concave area on the circuit board to deform downward, thereby adjusting the flatness of the circuit board. The whole-board device 1 provided in the present application can control the accuracy of the up and down movement of the lifting seat 12 by controlling the driver 15, and use the correction of the lifting part 14 or the adsorption part 13 to control the flatness of the circuit board within ±1mm, which can meet the AOI equipment detection requirements.

[0062] In this application, both the suction member 13 and the lifting member 14 are detachably mounted on the upper surface of the lifting base 12. During use, the suction member 13 or the lifting member 14 can be selected and installed on the upper surface of the lifting base 12 according to the concave and convex conditions of the circuit board. The suction member 13 and the lifting member 14 can be installed separately or simultaneously on the upper surface of the lifting base 12.

[0063] In one embodiment, in a non-working state, the top height of the lifting member 14 is slightly lower than the top height of the adsorption member 13. For a scenario where the circuit board bulges upward, the lifting member 14 and the adsorption member 13 move together to below the position to be adsorbed under the movement of the lifting seat 12. Since the adsorption member 13 is slightly higher than the lifting member 14, the adsorption member 13 is the first to contact the circuit board in the whole board device 1. The adsorption member 13 adsorbs the convex plate position and generates a downward contraction force through airflow control, thereby causing the upward protruding position of the circuit board to move downward. In addition, due to the presence of the lifting member 14, the adsorption member 13 is prevented from over-adsorbing the protruding position of the circuit board. Through the joint action of the adsorption member and the lifting member, the control accuracy of the flatness of the circuit board is improved.

[0064] In one embodiment, for the scenario where the circuit board is recessed downward, since the top of the adsorption member 13 is higher than the lifting member 14, the adsorption member 13 will interfere with the lifting member 14. Therefore, in order to avoid the interference of the adsorption member, for the scenario where the recessed circuit board needs to be lifted up, the adsorption member 13 needs to be removed before lifting.

[0065] In one embodiment, the whole-board device 1 has only the adsorption member 13 but no lifting member 14. The adsorption member 13 is used as a soft ejector pin, so that the adsorption member 13 can both adsorb and pull the circuit board downward and lift the circuit board.

[0066] In one embodiment, the board leveling device 1 is provided with a suction member 13 and a lifting member 14, both of which are disposed on a lifting base 12. Either the suction member 13 or the lifting member 14 can be raised or lowered to adjust the height, or both can be raised or lowered to adjust the height. Without requiring removal of the suction member 13 or the lifting member 14, interference between the suction member 13 and the lifting member 14 can be avoided during the process of leveling the circuit board.

[0067] In one embodiment, the lifting member 14 includes a base 141 and a pin 143 having a connecting end and a lifting end. The base 141 is mounted on the lifting base 12, and the connecting end of the lifting member 14 is threadedly connected to the base 141. For example, the base 141 is provided with an adjustment hole 148 having an internal thread, and the pin 143 is provided with an external thread that mates with the adjustment hole 148. The connecting end of the pin 143 is threadedly connected to the base 141. A sealing ring is mounted on the base 141, which is fitted around the pin 143 and located at the opening of the adjustment hole 148 to prevent dust and the like from entering the adjustment hole 148 and affecting the vertical adjustment of the pin 143.

[0068] The ejector pin 143 is a hexagon socket set screw with an external thread or a hexagon socket set screw with an external thread. By driving the ejector pin 143 to rotate, the ejector pin 143 can move up and down to achieve the initial height adjustment of the ejector pin 143, so that the lifting height of the ejector pin 143 can be adjusted according to different circuit boards, which is convenient for debugging the lifting part 14 and avoids the stroke limitation of the driver 15 such as the cylinder 151, which makes it impossible to adjust the flatness of the circuit board. At the same time, the relative height between the top of the ejector pin 143 and the top of the adsorption part 13 can be adjusted to avoid interference.

[0069] Optionally, the lifting member 14 also includes a first magnetic body 144, which is a permanent magnet. The first magnetic body 144 is provided on the base 141, and the lifting seat 12 has a first magnetic portion. The lifting seat 12 can be made of a material that can be attracted by a magnet as a whole, or a partial area can be made of a material that can be attracted by a magnet to form the first magnetic portion, or a magnet that is attracted to the first magnetic body 144 is provided on the lifting seat 12 to form the first magnetic portion. The base 141 is installed on the lifting seat 12 by the attraction between the first magnetic body 144 and the first magnetic portion. In this embodiment, the lifting seat 12 is made of Q235 material, and the lifting seat 12 and the first magnetic body 144 can be attracted to each other to achieve rapid installation of the lifting member 14. The lifting member 14 can be moved to any position on the lifting seat 12, which can better adapt to the whole board requirements of different PCB boards.

[0070] Furthermore, the base 141 includes a bottom shell 145 and a cover 146, with an adjustment hole 148 provided in the cover 146. The interior of the bottom shell 145 is a stepped hollow structure. A portion of the cover 146 is mounted inside the bottom shell 145, and the top of the cover 146 and the cavity corresponding to the second step of the bottom shell 145 together enclose a receiving chamber 140. The receiving chamber 140 is a cylindrical cavity, and the first magnetic body 144 is a cylindrical shape that matches the receiving chamber 140. The first magnetic body 144 is mounted in the receiving chamber 140. The first magnetic body 144 is a strong magnet, and the magnetic force can pass through the bottom of the bottom shell 145 to act on the lifting seat 12, thereby achieving the installation of the first magnetic body 144. The installation of the first magnetic body 144 in the receiving chamber 140 can prevent the first magnetic body 144 from being separated from the base 141 due to external forces during operation of the lifting member 14.

[0071] Furthermore, a socket 147 connected to the accommodating chamber 140 is provided on the bottom shell 145, and the bottom shell 145 is in contact with the lifting seat 12. The socket 147 is located at the bottom of the bottom shell 145, and an avoidance hole is provided on the first magnetic body 144. The socket 147, the accommodating chamber 140, and the adjustment hole 148 are connected in sequence from bottom to top, so that the adjustment tool can pass through the socket 147, the accommodating chamber 140, and the adjustment hole 148 in sequence from bottom to top, and then the adjustment tool is stuck in the hexagonal socket on the lower end surface of the ejector pin 143, which is convenient for adjusting the height of the ejector pin 143. At the same time, the adjustment hole 148 is provided to reduce obstruction and also to improve the adsorption force between the first magnetic body 144 and the first magnetic part of the lifting seat 12.

[0072] In one embodiment, the lifting member 14 also includes a top screw 142. The top screw 142 is installed in the adjustment hole 148. The external thread of the connecting end of the top screw 142 is threadedly connected to the internal thread of the adjustment hole 148. The top screw 142 is located below the ejector pin 143 and is connected or abutted with the connecting end of the ejector pin 143. When the connecting end of the ejector pin 143 abuts the top screw 142 below, when the top screw 142 moves downward, the ejector pin 143 moves downward due to gravity. The connecting end of the ejector pin 143 extends from top to bottom into the adjustment hole 148. The adjustment hole 148 can not only accommodate the connecting end of the ejector pin 143, but also provide a guide for the up and down movement of the ejector pin 143, thereby preventing the ejector pin 143 from swinging when it moves up and down to adjust the height or when lifting the circuit board. The upper end of the top screw 142 is stuck in the hexagonal socket of the ejector pin 143. By driving the top screw 142 to rotate, the top screw 142 is moved up and down, thereby realizing the up and down movement of the ejector pin 143. The ejector screw 142 can not only adjust the height of the ejector pin 143 , but also pre-tighten and position the ejector pin 143 after the height adjustment is completed, thereby preventing the ejector pin 143 from moving during the circuit board leveling process.

[0073] Optionally, an adjustment hole 148 is provided on the cover body 146 and communicated with the accommodating cavity. The height of the ejector 143 can be adjusted by removing the base 141 from the lifting seat 12 and then inserting the adjustment tool into the socket 147 and the adjustment hole 148 to drive the hexagonal head of the ejector 143 to rotate.

[0074] Optionally, a buffer 149 is provided at the lifting end of the ejector pin 143. The buffer 149 can be a flexible body such as a silicone pad or sponge, or can be a rubber that wraps the lifting end of the ejector pin 143. The buffer 149 can prevent the lifting end of the ejector pin 143 from damaging the surface of the circuit board.

[0075] The lift member 14 of the present invention has a large height adjustment stroke, which can cope with various application scenarios. The diameter of the lift pin 143 of the lift member 14 is small, and the direct contact between the lift pin 143 and the PCB board is only 4mm, which can avoid many components on the PCB and has better adaptability.

[0076] In one embodiment, the adsorption component 13 includes a bracket 131 and a suction nozzle 132 provided on the bracket 131. The suction nozzle 132 can be mounted on the bracket 131 in an adjustable manner up and down. The suction nozzle 132 is fixed to the bracket 131 after being moved up and down relative to the bracket 131 to adjust the height. Exemplarily, the lower end of the suction nozzle 132 is a threaded rod 136 with an external thread. The suction nozzle 132 is fixed to the bracket 131 by the screw rod 136 and the nut 137. The height of the suction nozzle 132 is adjusted by the fixed position of the nut 137. The threaded rod 136 is fixedly connected to the bracket 131 by at least one nut 137. The adsorption component 13 can adjust the height of the suction nozzle 132 by adjusting the position of the upper and lower nuts 137 on the threaded rod 136.

[0077] In one embodiment, screw holes are provided on the bracket 131 , and the bracket 131 is fixed to the lifting base 12 by screws. The bracket 131 and the lifting base 12 can be directly locked by the screws, and the installation of the bracket 131 is more stable.

[0078] In one embodiment, the bracket 131 is further provided with a second magnetic body 133, which can be a permanent magnet. The suction nozzle 132 can use negative pressure to adsorb the lower end surface of the circuit board. The lifting seat 12 has a second magnetic portion, and the bracket 131 is installed on the lifting seat 12 through the attraction between the second magnetic body 133 and the second magnetic portion. The lifting seat 12 can be made of a material that can be adsorbed by a magnet as a whole, or a part of the area can be made of a material that can be adsorbed by a magnet to form the second magnetic portion. The lifting seat 12 can also be provided with a magnet that is attracted to the second magnetic body 133 to form the second magnetic portion. The lifting seat 12 and the second magnetic body 133 can be attracted to each other to achieve rapid installation of the adsorption component 13. The adsorption component 13 can be moved to any position on the lifting seat 12, which can better meet the whole board requirements of different PCB boards.

[0079] Furthermore, the bracket 131 is Z-shaped or stepped, and the bracket 131 is installed on the lifting seat 12 to form an avoidance space. The lower end of the suction nozzle 132 can extend into the avoidance space through the card hole on the bracket 131. The bracket 131 is provided with a fifth connecting hole, and the second magnetic body 133 is installed on the bracket 131 by screws through the fifth connecting hole. Specifically, the bracket 131 includes a first plate body, a second plate body, and a third plate body connected in sequence. The first plate body, the second plate body, and the third plate body are integrally formed, the first plate body and the second plate body can be perpendicular to each other or the angle between the first plate body and the second plate body is within a preset range, the third plate body and the second plate body can be perpendicular to each other, the first plate body and the third plate body are parallel to each other and the first plate body is located above the third plate body, the first plate body is connected to one end of the second plate body, and the third plate body is connected to the other end of the second plate body. The second magnetic body 133 is installed on the lower end surface of the third plate body, and the suction nozzle 132 is installed on the first plate body. The first plate body and the lifting base 12 are spaced apart from each other from top to bottom to form an avoidance space.

[0080] Optionally, the suction member 13 further includes a fixing seat 134 provided on the lifting seat 12 and a negative pressure generator 135 provided on the fixing seat 134. The negative pressure generator 135 is connected to the suction nozzle 132, and the negative pressure generator 135 can be used to enable the suction nozzle 132 to generate negative pressure to suction the lower end surface of the circuit board.

[0081] Furthermore, there are multiple adsorption members 13 and spaced apart on the lifting base 12, and multiple lifting members 14 and spaced apart on the lifting base 12. The number of adsorption members 13 and lifting members 14 can be set according to the number of concave and convex positions, and the flattening efficiency of the circuit board is higher.

[0082] In one embodiment, a third magnetic body 114 is provided on the base 11, and the third magnetic body 114 is a permanent magnet. The base 11 can be adsorbed onto the detection equipment through the third magnetic body 114, so as to facilitate the installation of the whole board device 1. Specifically, the base 11 includes an adsorption block 114 connected to the support block 111. There are two adsorption blocks 114 and they are symmetrically distributed on both sides of the support block 111. Each adsorption block 114 is provided with four third magnetic bodies 114 to facilitate the whole board device 1 to be more firmly adsorbed on the frame 2 of the detection mechanism. The installation by magnetic attraction can also facilitate the free movement of the whole board device 1 to change the installation position. The whole board device 1 can move within the specified stroke on the frame 2 to cope with PCB boards of different sizes.

[0083] Optionally, the base 11 includes a support block 111 and a connecting block 112 mounted on the support block 111. The support block 111 is a square block, and there are two connecting blocks 112 symmetrically distributed on two sides of the support block 111, and there are two adsorption blocks 114 symmetrically distributed on the other two sides of the support block 111. The driver 15 includes a cylinder 151 mounted on the support block 111, a push plate 152 connected to the output rod of the cylinder 151, and a guide rod 155 slidably mounted on the support block 111. The lifting seat 12 is locked to the push plate 152 by countersunk screws. The lifting seat 12 is mounted on the push plate 152, and the guide rod 155 is connected to the push plate 152 to improve the stability of the lifting seat 12 in moving up and down. The whole board device 1 of the present application has a large stroke, with a maximum stroke of 200 mm. The advantage of the large stroke is obvious, which allows for a larger board height under the PCB board, which can effectively prevent the track of the detection mechanism from interfering with the whole board device 1 when returning to the track origin at startup.

[0084] In one embodiment, the lifting base 12 is provided with a first connection hole and a second connection hole. The push plate 152 is provided with a third connection hole, and the lifting base 12 is connected to the push plate 152 via screw fasteners passing through the first and third connection holes. A reinforcement plate 18 is sleeved on the base 141. The reinforcement plate 18 has a limiting hole and is sleeved on the base 141 through the limiting hole. The reinforcement plate 18 has a mounting hole and is connected to the lifting base 12 via screw fasteners passing through the second and mounting holes. This strengthens the installation stability of the lifting member 14. The lifting member 14 may deviate due to impact after long-term operation. The reinforcement plate 18 can prevent the lift pin 143 of the lifting member 14 from moving due to vibration during long-term operation.

[0085] Optionally, there are multiple first connecting holes and they are spaced apart along the circumference of the output rod of the cylinder 151. Specifically, the lifting seat 12 is a rectangular plate, and two of the lifting seat 12 are diagonally installed with adsorption members 13, and the other two are diagonally installed with lifting members 14. Multiple first connecting holes are spaced apart along the center circumference of the lifting seat 12. By rotating the lifting seat 12, the positions of the adsorption members 13 and the lifting members 14 can be adjusted, and then the screw fasteners are passed through the first connecting holes corresponding to the third connecting holes to achieve the installation and fixation of the lifting seat 12. Furthermore, the base 11 is also equipped with a locking screw 116, and the locking screw 116 is threadedly connected to the base 11. Specifically, the base 11 also includes a locking block 115. The locking block 115 is connected to the support block 111, and the locking screw 116 is installed on the locking block 115. A clamping gap is formed between the locking screw 116 and the adsorption block 114. After the adsorption block 114 of the base 11 is adsorbed on the frame 2 through the third magnetic body 114, the clamping gap size is adjusted by rotating the locking screw 116 so that the locking screw 116 and the adsorption block 114 are clamped on the frame 2, thereby improving the stability of the base 11 installed on the frame 2.

[0086] Furthermore, the driver 15 also includes a limit plate 153. The limit plate 153 is connected to the guide rod 155, and the limit plate 153 limits the movement of the output rod of the cylinder 151. The base 11 or other components installed on the base 11 are located on the movement path of the limit plate 153 when it moves upward. When the driver 15 drives the lifting seat 12 upward away from the base 11, the base 11 or other components installed on the base 11 are located on the movement path of the limit plate 153 when it moves upward. The limit plate 153 is used to limit after the cylinder 151 drives the lifting seat 12 upward to its position, thereby limiting the upward movement of the output rod of the cylinder 151 and preventing the ejector pin 143 from moving too far and damaging the circuit board.

[0087] In one embodiment, the whole plate device 1 further includes an adjusting screw 16 threadedly connected to the base 11, and the adjusting screw 16 is located on the moving path of the limit plate 153 to adjust the stroke of the output rod of the cylinder 151. Specifically, the base 11 is provided with a threaded hole adapted to the adjusting screw 16, and the adjusting screw 16 is arranged vertically. When the adjusting screw 16 is rotated, the entire adjusting screw 16 moves up and down, thereby adjusting the height of the lower end of the adjusting screw 16. The lower end of the adjusting screw 16 is located on the upward moving path of the limit plate 153. When the limit plate 153 moves upward, it abuts against the lower end of the adjusting screw 16. By rotating the adjusting screw 16, the height of the lower end of the adjusting screw 16 is adjusted, thereby adjusting the stroke of the output rod of the cylinder 151.

[0088] Furthermore, the whole plate device 1 also includes a buffer 17 connected to the base 11. The buffer 17 is arranged parallel to the guide rod 155 and is located on the moving path of the limit plate 153. Specifically, the buffer 17 and the adjusting screw 16 are respectively installed on both sides of the base 11. The buffer 17 is located on the upward movement path of the limit plate 153. When the limit plate 153 moves upward and abuts against the lower end of the adjusting screw 16, the limit plate 153 will abut against the buffer 17 to achieve buffering, thereby avoiding a rigid collision between the limit plate 153 and the adjusting screw 16. In this way, the contact between the oil pressure buffer 17 and the limit plate 153 can absorb the impact energy and reduce the impact force.

[0089] Optionally, the driver 15 further includes a throttle valve 154. The throttle valve 154 is in communication with the cylinder 151. The throttle valve 154 is an airflow throttle valve 154, and there are two throttle valves 154, which can adjust the lifting speed of the cylinder 151.

[0090] The whole-board device provided in the present application can adjust the circuit board to a preset flatness through an adsorption component and / or a lifting component. Moreover, by controlling at least one of the height of the lifting seat, the height of the adsorption component, and the height of the lifting component, the adjustment error of the flatness of the circuit board is continuously reduced, and the control accuracy is greatly improved.

[0091] like Figure 6As shown, at the same time, the embodiment of the present application also provides a detection device, such as an optical detection device or some other automated equipment. The detection device includes a frame 2 and the above-mentioned whole plate device 1, a track transmission mechanism above the whole plate device, an imaging mechanism, etc. There are multiple whole plate devices 1 and they are arranged at intervals. The weight of a single whole plate device 1 is about 1.2 kg. It is light in weight, compact in size, and can be moved flexibly and freely. The whole plate device 1 can be used in combination and coordination alone or in multiples. The number of adsorption parts 13 of each whole plate device 1 and the number of adsorption parts 13 can also be freely combined to meet the use requirements of different working conditions and the personalized needs of various products. It has strong compatibility. The frame 2 is at least partially a third magnetic part with magnetism. The base 11 is installed on the frame 2 by the attraction of the third magnetic body 114 and the third magnetic part, so as to realize the rapid installation of the whole plate device 1. The whole plate device 1 can also be fixed to the frame by screws or the like to improve the stability of the whole plate device 1.

[0092] When the detection equipment detects the circuit board, the circuit board is placed on the detection equipment and the circuit board is placed above the whole board device 1. When the circuit board is concave downward, the driver 15 drives the lifting seat 12 to move upward, and the lifting member 14 on the lifting seat 12 lifts the concave part of the circuit board to achieve correction. When the circuit board is convex upward, the driver 15 drives the lifting seat 12 to move upward, and the adsorption member 13 on the lifting seat 12 adsorbs and pulls down the convex part of the circuit board to achieve correction. The lifting mechanism can also be combined to prevent the circuit board from being lower than the preset horizontal plane after adsorption, so as to achieve adjustment of the flatness of the circuit board, thereby facilitating the camera of the detection equipment to take pictures and detect, and improving the efficiency and accuracy of circuit board detection.
