[0035] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0036] like Figure 1 and Figure 2 As shown, in one embodiment, the detection equipment 100 includes a supporting device 1, a turntable 2, a driving device, a loading device 3, an unloading device 4, a detection device 5, a first visual recognition device 6 and a control device; the turntable 2, the driving device, the loading device 3, the unloading device 4, the detection device 5, the first visual recognition device 6 and the control device are all installed on the supporting device 1.

[0037] The turntable 2 is provided with a placement area 21, and the turntable 2 can rotate around its own axis relative to the support device 1, so that each placement area 21 can be rotated in sequence to correspond to the loading device 3, the detection device 5 and the unloading device 4; the driving device is used to drive the disk to rotate; the loading device 3 is used to transfer the circuit board in the loading area to the corresponding placement area 21; the detection device 5 is used to detect the circuit board on the corresponding placement area 21; the unloading placement area 21 is used to move the circuit board on the corresponding placement area 21 out of the turntable 2; the first visual recognition device 6 is used to identify the relative position between the loading device 3 and the circuit board placed in the loading area; the control device is respectively connected to the driving device, the loading device 3, the unloading device 4, the detection device 5 and the first visual recognition device 6, so as to control the operation of each device. In addition, the circuit board can be FPC, PCB, etc.

[0038] In this embodiment, when working, the loading device 3 can transfer the circuit board in the loading area to the corresponding placement area 21; then, the turntable 2 rotates to transfer the circuit board to the detection device 5 (that is, the placement area 21 is moved to correspond to the detection device 5), and stops rotating; then, the detection device 5 detects the circuit board; then, the turntable 2 rotates again to transfer the circuit board to the unloading device 4 (that is, the placement area 21 is moved to correspond to the unloading device 4), and stops moving; then, the unloading device 4 can move the circuit board in the placement area 21 out of the turntable 2; then, the turntable 2 rotates again to move the placement area 21 to correspond to the loading device 3 again. That is, through the setting of this embodiment, automatic loading and unloading can be realized when the circuit board is detected, thereby improving production efficiency. In addition, the use of the turntable 2 to move the circuit board between the devices can make the detection setting more integrated.

[0039] In addition, when working, the first visual recognition device 6 can identify the relative position between the circuit board in the placement area 21 and the loading device 3. The control device can control the loading device 3 to move to a suitable position according to the position recognition result to grab the circuit board in the loading area, and can accurately move the circuit board to a suitable position in the placement area 21, thereby ensuring that the circuit board is placed more accurately in the placement area 21. This can improve the detection effect of the detection device 5 on the circuit board, and avoid the circuit board from being damaged by the detection device 5 or other devices due to deviation in position placement.

[0040] In addition, corresponding marks are set on the feeding device 3 and the circuit board, and the first visual recognition device 6 can recognize the relative position of the two objects according to the marks on the two objects. Among them, the recognition visual device recognizes the relative position of two objects by vision, which belongs to the existing design and will not be described in detail in this embodiment.

[0041] Since the relative position of the feeding device 3 and the placement area 21 can be fixed, the feeding device 3 can place the circuit board grabbed in a suitable place. Of course, in other embodiments, the first visual recognition device 6 can also recognize the relative position of the feeding device 3 and the storage area to further improve the placement accuracy of the circuit board in the placement area 21.

[0042] The turntable 2 can rotate around its own axis relative to the supporting device 1 so that the placement area 21 can be rotated in sequence to correspond to the loading device 3, the detection device 5 and the unloading device 4. In fact, it means that when the turntable 2 rotates in the same direction, the placement area 21 can be rotated in sequence to correspond to the loading device 3, the detection device 5 and the unloading device 4, that is, the placement area 21 first corresponds to the loading device 3, then rotates to correspond to the detection device 5, and then rotates to correspond to the unloading device 4; the direction can be clockwise or counterclockwise.

[0043] In one embodiment, the turntable 2 may be a disc structure, and the control device may be a PLC, a single chip microcomputer, a computer, etc. The driving device may be a servo motor, etc.

[0044] In one embodiment, a plurality of placement areas 21 are provided, and each placement area 21 is evenly arranged around the axis of the turntable 2; and when one of the loading device 3, the detection device 5, and the unloading device 4 corresponds to one placement area 21, the other two of the loading device 3, the detection device 5, and the unloading device 4 also correspond to one placement area 21. In this way, during the working process, when the loading device 3 is loading, the detection device 5 can perform detection, and the unloading device 4 can unload at the same time, thereby further improving the production efficiency.

[0045] In addition, the total number of the loading devices 3 , the detecting devices 5 and the unloading devices 4 may be equal to or less than the number of the placement areas 21 .

[0046] In the scenario where there are multiple placement areas 21, each detection device 5 can correspond to the corresponding placement area 21 at the same time, wherein one detection device 5 corresponds to one placement area 21 at a time. At this time, some detection devices 5 can also detect the same function of the circuit board.

[0047] In actual scenarios, the circuit board is usually located above the placement area 21, that is, the turntable 2 supports the circuit board in the vertical direction, and the detection point of the circuit board is also located above. During detection, the detection device 5 presses the circuit board onto the turntable 2 from above the circuit board (at this time, the probe of the detection device 5 is electrically contacted with the detection point) to detect the circuit board.

[0048] like Figure 2 As shown, in one embodiment, a plurality of detection devices 5 are provided; when the turntable 2 rotates around its own axis relative to the support device 1, it can drive the placement area 21 to rotate in sequence to correspond to each detection device 5. Among them, each detection device 5 can detect different functions of the circuit board. "Multiple" means greater than or equal to two, and "multiple" has the same meaning in each embodiment.

[0049] In one embodiment, the placement area 21 is provided with an avoidance hole, which passes through the turntable 2 along the axis of the turntable 2; the detection device 5 includes a support module 51 and a detection module 52 (refer to Figure 3), in the axial direction of the turntable 2, the support module 51 and the detection module 52 are respectively located on both sides of the turntable 2; the support module 51 and the detection module 52 are opposite to each other at the avoidance hole, so as to respectively contact the two sides of the circuit board placed on the placement area 21 at the avoidance hole. When working, the support module 51 is used to support the circuit board, and the detection module 52 is used to detect the circuit board. At this time, the probe of the detection module 52 contacts the detection point of the circuit board from the side of the circuit board away from the support module 51. Among them, the support module 51 can be located below the detection module 52.

[0050] Corresponding electronic components are usually arranged on the circuit board. In order to avoid damage to the electronic components on the circuit board, corresponding avoidance holes are arranged in the placement area 21. When the circuit board is placed in the placement area 21, the electronic components on the circuit board can be located in the avoidance holes.

[0051] However, in this scenario, some detection points of the circuit boards may also be located in the area opposite to the avoidance hole. At this time, when the probe of the detection device 5 hits the detection point from top to bottom, the circuit board will bend downward, thereby affecting the detection effect.

[0052] Therefore, in this embodiment, the support module 51 supports the circuit board below the circuit board to prevent the circuit board from being bent by the probe. The support module 51 can only support the area where the detection point is located to avoid damage to the electronic components on the circuit board during detection.

[0053] In one embodiment, the support module 51 includes a support driver and a support column. The support driver is connected to the support platform 11 and is used to drive the support column to move up and down. When the support column moves upward, it can extend into the avoidance hole to support the circuit board. In addition, the support driver can be a cylinder or the like.

[0054] The detection module 52 includes a detection bracket, a detection drive, a probe and a detector. The detection bracket is connected to the support device 1. The detection drive is connected to the detection bracket and is located above the turntable 2. The probe is installed on the detection drive and connected to the detector. The detection drive is used to drive the probe to move up and down. When the elasticity moves downward, it can electrically conflict with the detection point of the circuit board in the placement area 21, so that the detector can perform corresponding detection on the circuit board.

[0055] like Figure 3As shown, in one embodiment, the support device 1 includes a support platform 11, and the turntable 2 is arranged on the support platform 11; the detection module 52 is arranged on the side of the support platform 11 close to the turntable 2; the support module 51 is arranged on the side of the support platform 11 away from the turntable 2; a window is provided on the support platform 11, and the support module 51 can pass through the support platform 11 from the window so as to contact the circuit board placed on the placement area 21 at the avoidance hole. Among them, the window is a through hole that passes through the support platform 11 along the axis of the turntable 2.

[0056] In one scenario, the turntable 2 and the detection module 52 are located above the support platform 11, and the support module 51 is located below the support platform 11. The arrangement of this embodiment can improve space utilization and reduce the height of the turntable 2 relative to the support platform 11.

[0057] In addition, only one window may be provided. When a storage area is rotated to correspond to the detection device 5, the avoidance hole on the storage area will be opposite to the window, so that the support column of the support module 51 can pass through the support platform 11 from the window and extend into the avoidance hole to support the circuit board.

[0058] In one embodiment, the support device 1 also includes a support seat and a support frame. The support platform 11 is installed on the support seat, and the support frame surrounds the outer side of the support platform 11. A corresponding protective plate can be installed on the support frame. The protective plate can protect the turntable 2 to prevent it from colliding with other objects or people.

[0059] like Figure 4 As shown, in one embodiment, the turntable 2 includes a disk body 22 and a plurality of jigs 23; the disk body 22 is rotatably connected to the support device 1, and a plurality of installation areas are provided on the disk body 22, and each installation area is evenly arranged around the axis of the disk body 22; one jig 23 is installed in one installation area, and one jig 23 is provided with a placement area 21; the jig 23 is detachably connected to the disk body 22. When the jig 23 is worn, only the damaged jig 23 needs to be replaced, which can reduce maintenance costs.

[0060] The axis of the disk body 22 is the axis of the turntable 2. The fixture 23 and the disk body 22 may be connected by bolts; or the two may be connected by a limiting column. In this case, the fixture 23 may be provided with a corresponding limiting hole, and the disk body 22 may be provided with a corresponding limiting column. When the fixture 23 is placed on the disk body 22, the limiting column extends into the limiting hole to limit the relative position of the fixture 23 on the disk body 22. There may be multiple limiting columns and limiting holes, and one limiting column cooperates with one limiting hole, so that the installation position of the fixture 23 on the disk body 22 can be limited.

[0061] In addition, the installation area can be a stepped hole provided on the disc body 22, wherein the stepped hole includes a first hole and a second hole along the direction from top to bottom, the aperture of the first hole is larger than the aperture of the second hole, and a step surface is formed between the two, and the fixture 23 is installed on the step surface. The fixture 23 can be limited by the hole wall of the first hole, so that the installation of the fixture 23 is more convenient.

[0062] In one embodiment, the loading device 3 includes a first loading drive module, a second loading drive module and a loading suction cup, the first loading drive module is installed on the supporting device 1, the second loading drive module is installed on the first loading drive module, and the loading suction cup is installed on the second loading drive module; one of the first loading drive module and the second loading drive module is used to drive the loading suction cup to move along the X-axis, Y-axis and Z-axis respectively, and the other is used to drive the loading suction cup to rotate around the Z-axis; wherein the Z-axis is parallel to the axis of the turntable 2.

[0063] In one scenario, the Z axis is perpendicular to the Y axis, the Z axis is perpendicular to the X axis, the X axis is perpendicular to the Y axis, and the Z axis is parallel to the up and down direction. The first loading drive module can drive the second loading drive module and the loading suction cup to move along the X axis, Y axis and Z axis respectively, and the second loading drive module can drive the loading suction cup to rotate around the Z axis.

[0064] The first feeding drive module can be installed on the support seat or the support frame 12, and the first feeding module can be a module in the prior art that can drive the object to move in three dimensions. At the same time, the second feeding drive module can be a module in the prior art such as a motor that can drive the object to rotate.

[0065] The loading suction cup is connected to a corresponding negative pressure device so as to grab the circuit board by vacuum adsorption.

[0066] like Figure 5 and Figure 6 As shown, in one embodiment, the detection device 100 further includes a conveying device 7 and a first lifting device 8; the conveying device 7 is connected to the supporting device 1 and is used to transfer the material tray, in which the circuit board is placed; the first lifting device 8 includes a first lifting drive module 81 and a first lifting plate 82, and the first lifting drive module 81 is used to drive the first lifting plate 82 to move up and down; when the first lifting plate 82 moves upward, it can lift the material tray on the conveying device 7, and the loading device 3 is used to transfer the circuit board in the material tray lifted by the first lifting plate 82 to the corresponding placement area 21; when the first lifting plate 82 lifts the material tray on the conveying device 7, the conveying device 7 can convey other material trays to pass under the material tray lifted by the first lifting plate 82; when the first lifting plate 82 moves downward, it can place the material tray lifted by it on the conveying device 7. In this embodiment, the conveying device 7 can be docked with the conveying device of other equipment to facilitate the transfer of the material tray equipped with the circuit to the detection device 100.

[0067] Among them, when the material tray moves to a suitable position, the first lifting device 8 can lift it up, and at this time, the circuit board in the material tray is in the loading area. Moreover, at this time, the first lifting drive module is in the maximum lifting position, and the material tray placed on the first lifting plate 82 can be regarded as the loading area. Usually, there are multiple circuit boards placed in the material tray, so lifting the material tray can facilitate the loading device 3 to grab the circuit board, and will not affect the conveying of other material trays by the conveying device 7. Of course, in other embodiments, the loading area can also be located on other objects used to support the placement of circuit boards.

[0068] like Figure 6 As shown, in one embodiment, the conveying device 7 can be a conveyor belt. The conveyor belt can transfer materials along the Y-axis direction. The first lifting drive module 81 includes a first cylinder 811 and a second cylinder 812, and the first cylinder 811 and the second cylinder 812 are arranged at intervals on both sides of the conveying device 7 along the X-direction. The first lifting plate 82 includes a first plate 821 and a second plate 822, and the first plate 821 is connected to the first cylinder 811, and the second plate 822 is connected to the second cylinder 812. The first plate 821 and the second plate 822 are also located outside the conveying device 7. After the tray is placed on the conveying device 7, both ends of the tray in the X-axis direction are located outside the conveying device 7, and both ends of the tray in the Z-axis direction are located above the first plate 821 and the second plate 822, respectively.

[0069] When the first plate 821 and the second plate 822 rise at the same time, they can respectively contact the two ends of the material tray to lift the material tray. At this time, when other material trays pass through the first lifting device 8, the first lifting device 8 will not interfere with them. When the first plate 821 and the second plate 822 descend at the same time, the material tray can be placed on the conveying device 7.

[0070] When the first cylinder 811 and the second cylinder 812 are at the maximum lifting position (i.e., when the first lifting drive module is at the maximum lifting position), the first plate 821 and the second plate 822 lift the material tray to the maximum height, and at this time, the loading device 3 can grab the circuit board. When the first cylinder 811 and the second cylinder 812 are at the maximum retracted position (i.e., when the first lifting drive module is at the maximum retracted position), the heights of the first plate 821 and the second plate 822 are both lower than the surface of the conveying device 7 for supporting the material tray, so that the material tray can be placed on the conveying device 7.

[0071] like Figure 5 and Figure 6As shown, in one embodiment, the detection equipment 100 also includes a second lifting device 9; the second lifting device 9 includes a second lifting drive module and a second lifting plate, the second lifting drive module is used to drive the second lifting plate to move up and down, so that the second lifting plate can switch between the first position and the second position; when the second lifting plate is in the first position, the second lifting plate is located above the conveying device 7, and the unloading device 4 is used to transfer the circuit board on the turntable 2 to the material tray on the second lifting plate located in the first position; when the second lifting plate is in the first position, the conveying device 7 can convey other material trays from under the second lifting plate; when the second lifting plate moves downward to the second position (the first position is above the second position), the material tray lifted by it can be placed on the conveying device 7.

[0072] Among them, when the second lifting plate is in the first position, the empty material tray placed on it is the unloading area, and the unloading device 4 is used to place the circuit board on the turntable 2 in the unloading area. In addition, the structural setting of the second lifting device 9 can be the same as the first lifting device 8, and this embodiment will not be described in detail here. Moreover, when the second lifting plate is in the first position, the second lifting drive module is in the maximum lifting position, and when the second lifting plate is in the second position, the second lifting drive module is in the maximum retracted position.

[0073] In one embodiment, the detection device 100 further includes a second visual recognition device, which is used to identify the relative position relationship between the unloading device 4 and the unloading area, so that the circuit board can be placed in the unloading area more accurately.

[0074] In addition, the unloading area usually places circuit boards detected as good products. At this time, the detection equipment 100 also includes a defective product placement area 21, which is used to place circuit boards detected as defective products, wherein the defective product placement area 21 can be located on the support platform 11.

[0075] In one embodiment, the detection device 100 further includes a third visual recognition device, which is used to scan and recognize the circuit board placed in the placement area 21 corresponding to the loading device 3 .

[0076] The embodiment of the utility model further provides a circuit board detection line, which includes the detection device 100 described in any one of the above embodiments.

[0077] In one embodiment, there are multiple testing devices 100, and each testing device 100 is connected in series in sequence; the conveying device 7 of one testing device 100 can convey the material tray to the conveying device 7 of another testing device 100. The sequential connection of each testing device 100 means that after one testing device 100 completes one circuit board test, it can flow to another testing device 100, until it flows to the last testing device 100.

[0078] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
