Description

Technical Field

[0001] The present invention relates to the field of product automatic production equipment, and particularly relates to a transfer and rotation device and a detection device. Background Art

[0002] In the field of automatic production equipment, workpieces are usually transferred through fixtures. Specifically, the workpieces are installed on the connections of the fixtures; in the automatic production of some products, in order to facilitate detection or processing, the connections need to be rotated to drive the workpieces to rotate. In the prior art, this is achieved by matching one fixture with a driving part that is rotationally locked with the connection, which results in a high cost; however, if only driving parts are provided at the corresponding workstations, the connections may rotate during the transfer process of the fixtures due to machine vibrations or other reasons, thereby causing the workpieces to rotate and resulting in an unsatisfactory processing or detection condition.

[0016] The NG product blanking mechanism is adapted to blank the relay semi-finished product when the appearance of the relay semi-finished product is judged to be NG.

[0017] Solution Six, based on Solution Five, the OK product blanking mechanism includes a first moving member, a second moving member and a transfer plate; the first moving member is adapted to drive the second moving member to move along the rotation axis direction of the relay semi-finished product at the OK product blanking station; the transfer plate is provided with a seating surface and a blanking convex block protruding from the seating surface, a first guide plate, a second guide plate and a limiting plate, the first guide plate and the second guide plate are arranged at intervals facing each other, the limiting plate and the blanking convex block are arranged at intervals facing each other, and the second moving member is adapted to drive the transfer plate to move relative to the relay semi-finished product in the vertical direction to a third position; at the third position, the seating surface is for the relay semi-finished product to seat on and the blanking convex block is inserted into the blanking groove, and the first moving member is adapted to, when the transfer plate is at the third position, drive the second moving member to move along this rotation axis direction and away from the jig so that the blanking convex block pushes the relay semi-finished product out of the jig.

[0018] Solution Seven, based on Solution Six, the number of the blanking convex blocks is multiple, and each of the blanking convex blocks is arranged along a second direction perpendicular to the rotation axis and the vertical direction, and the number of the first guide plate, the second guide plate and the limiting plate is adapted to the number of the blanking convex blocks; the OK product blanking mechanism further includes a third moving member, and the third moving member is adapted to drive the first moving member to move along the second direction to switch each of the blanking convex blocks to correspond to the relay semi-finished product at the OK product blanking station.

[0019] Solution Eight, based on Solution Five, further includes a first detection mechanism, a second detection mechanism, a third detection mechanism, a fourth detection mechanism, a fifth detection mechanism and a sixth detection mechanism;

[0020] The first detection mechanism is adapted to obtain a front image of the base to detect the injection molding condition of the base.

The first driving device is arranged corresponding to the working station of the third detection mechanism to drive the connecting piece corresponding to this working station to rotate and drive the relay semi-finished product to rotate until the mark faces up;

[0026] The second driving part is arranged corresponding to the line scan working station and is configured to drive the connecting piece corresponding to this working station to rotate 360° and then continue to rotate so that the opening of the blanking groove on the circumferential surface of the base body faces downwards.

[0027] Solution Ten, based on Solution Nine, further includes a sensor, a controller and an alarm that are electrically connected to each other. The first matching part is shown as a rotation stopping groove, and both ends of the rotation stopping groove extend to the circumferential surface of the connecting piece; the timing of the sensor is before the timing corresponding to the OK product blanking mechanism and after the timing corresponding to the sixth detection mechanism. The sensor detects the distance from the rotation stopping groove to detect whether the opening of the blanking groove on the circumferential surface of the base body faces downwards, and sends a warning signal when the opening of the blanking groove on the circumferential surface of the base body does not face downwards. When the controller receives the warning signal, it controls the alarm to alarm and pauses the detection device.

[0028] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. Solution One, the first driving part is used to drive the second driving part and the push block to move along the rotation axis direction of the workpiece at the working position, so that the output end of the second driving part moves towards the connecting piece and establishes a rotation stopping cooperation relationship with the first matching part. And the push block also slides towards the top block until it drives the top block to overcome the elastic force of the reset part and move to the second position by cooperating with the inclined surface of the third matching part. Through the action of the inclined surface, a vertically downward component force is applied to the top block, so that the top block can move to the second position. At this time, the second driving part can drive the connecting piece to drive the workpiece to rotate so as to realize detection or processing.

[0030] When the first driving member drives the second driving member and the pushing block to slide in a direction away from the fixture, the output end of the second driving member and the pushing block are disengaged from the fixture, so that the fixture can continue to be transferred along with the multi-station turntable without interfering with the driving device. At this time, under the action of the reset member, the top block automatically resets to the locked state. During the subsequent transfer process of the fixture, the connecting member will not rotate, so the workpiece will not rotate, which does not affect the subsequent workstations.

[0031] The first driving member drives the second driving member and the pushing block to slide simultaneously, which saves more energy compared to the second driving member and the pushing block sliding independently. And the driving device only needs to be set at the corresponding workstations, without corresponding to the fixtures one by one, saving costs.

[0032] 2. Solution two: The connecting member is provided with an anti-rotation portion, and the anti-rotation portion is adapted to be anti-rotationally connected to the workpiece. The anti-rotation portion is in the form of a groove or a protrusion, so as to achieve an anti-rotation cooperation relationship with the workpiece, so that the connecting member drives the workpiece to rotate, realizing anti-rotation while facilitating the installation or removal of the workpiece from the connecting member. In specific occasions, the anti-rotation portion also plays a supporting role.

[0033] 3. Solution three: The fixing portion is inserted into the hole of the workpiece to support the workpiece, and the assembly force between the workpiece and the fixing portion is increased to prevent it from being easily detached.

[0034] 4. Solution four: A detection device, which includes the above-mentioned transfer and rotation device and a line scan detection mechanism. It includes a line scan camera, and the receiving light of the line scan camera is perpendicular to the rotation axis of the relay semi-finished product when it is at the line scan workstation, so as to obtain an image of the entire coil. When the fixture is at the line scan workstation, the second driving member drives the connecting member and drives the relay semi-finished product, and the line scan camera obtains a full-circle image to detect the appearance of the coil of the relay semi-finished product, so as to prevent problems such as dirt and soldering on the coil appearance from causing poor conductivity or vulnerability of the final product.

[0035] 5. Solution five: It further includes a multi-station turntable, a feeding mechanism, an OK product discharging mechanism and an NG product discharging mechanism; a number of fixtures are provided corresponding to each workstation of the multi-station turntable one by one. The multi-station turntable has a compact structure and occupies a small space. The feeding mechanism is used to install the relay semi-finished product on the fixture at the feeding workstation and make the anti-rotation surface and the anti-rotation portion in anti-rotation cooperation, and the fixing portion is inserted into the iron core hole; the OK product discharging mechanism and the NG product discharging mechanism classify the products, so as to realize automatic production.

[0036] 6. Solution six: The method of using a stripping bump to push the relay semi-finished product out of the fixture can wait below the workpiece in advance, and only two steps of upward movement and backward movement are required to detach the workpiece. Compared with the manipulator, it requires fewer steps of upward movement (or forward movement), clamping and backward movement, has higher efficiency, and will not damage the workpiece.

[0037] 7. Solution VII: The number of stripping bumps is multiple. The third moving part is adapted to drive the first moving part to move along the second direction to switch each stripping bump corresponding to the relay semi-finished product at the OK product blanking station, so that multiple OK products can be collected and then uniformly transferred to the OK product placement location, saving energy.

[0038] 8. Solution VIII: The first detection mechanism ensures that there is no white edge on the substrate, thus ensuring the substrate strength; the second detection mechanism prevents the pins from falling off in the subsequent process; the third detection mechanism prevents the interference of the OK product blanking mechanism caused by material mixing and prevents assembly problems caused by product deformation; the fourth detection mechanism and the fifth detection mechanism prevent poor conductivity; the sixth detection mechanism prevents the pins from bending and causing fracture during subsequent assembly and prevents the magnetic flux of the same product from being different due to the coil being wound more or less; thus, corresponding detections are carried out on the interference of the semi-finished relay, and the product quality is controlled at the semi-finished product stage to prevent process waste caused by NG products flowing to the subsequent process.

[0039] 9. Solution IX: There are two driving devices, namely the first driving device and the second driving device. The first driving device is arranged corresponding to the station of the third detection mechanism to drive the connecting piece corresponding to this station to rotate and drive the relay semi-finished product to rotate so that the mark faces upward, so that the subsequent detection mechanism can obtain the desired image from above or below, which is more convenient. The second driving part is arranged corresponding to the line scan station and is configured to drive the connecting piece corresponding to this station to rotate 360° and then continue to rotate so that the opening of the stripping groove on the circumferential surface of the substrate faces downward, thereby preventing the OK product blanking mechanism from interfering with the semi-finished relay.

[0040] 10. Solution X: By setting sensors, it is possible to prevent the posture of the relay semi-finished product from being incorrect due to power failure, shutdown, etc. during the process, and there is no driving device for adjustment later. When reaching the OK product blanking station, the OK product blanking mechanism interferes with the relay semi-finished product, resulting in damage. BRIEF DESCRIPTION OF THE DRAWINGS

[0070] Refer to Figures 1-10 , a detection device, which is suitable for transferring and detecting the relay semi-finished product 5, refer to Figure 11, the semi-finished relay 5 is installed with a coil 52 and pins 53, and the reaction spring, contacts, and housing are not installed yet. The semi-finished relay 5 includes a base body 51, a coil 52, and pins 53; the base body 51 is further provided with an iron core hole 511 extending along the direction of its rotation axis, the coil 52 is wound around the base body 51 along its rotation axis and is electrically connected to the pins 53; the pins 53 are installed on the positive side of the base body 51 along its rotation axis, and in this embodiment, there are two pins 53 connected to the coil 52; the back side of the base body 51 along its rotation axis includes a rotation stopping surface 512 and a stripping groove 513, the rotation stopping surface 512 is parallel to its rotation axis, and the stripping groove 513 is in the form of a groove and opens on the circumferential surface of the base body 51; the side surface of the base body 51 is also provided with a mark for identifying the product model; the above-mentioned structures such as the stripping groove 513 are all used for subsequent assembly of other parts of the workpiece and do not require special processing.

[0071] Reference Figures 1-10 , the detection device includes a transfer and rotation device 1, a line scan detection mechanism 2, a multi-station turntable 3, a feeding mechanism, an OK product discharging mechanism 4, an NG product discharging mechanism, a first detection mechanism, a second detection mechanism, a third detection mechanism, a fourth detection mechanism, a fifth detection mechanism, a sixth detection mechanism, sensors, a controller, and an alarm.

[0072] The transfer and rotation device 1 is used to transfer the workpiece to the working position on the base and drive the workpiece located at the working position to rotate. In this embodiment, the base is a machine part fixed to the ground and does not move, the workpiece is the semi-finished relay 5, and the working position is the detection station of the semi-finished relay 5. It should be understood that in the automated application of other workpieces, it can also be a processing station, such as machining, labeling, etc.

[0073] Reference Figures 2-6 , the transfer and rotation device 1 includes a jig 11 and a driving device 12. Among them, there are several jigs 11, which are arranged corresponding to each station of the multi-station turntable 3 one by one. It should be understood that transportation can also be carried out through other forms besides the multi-station turntable 3.

[0074] Reference Figures 2-5The fixture 11 includes a seat body 111, a connecting member 112, a top block 113 and a reset member 114. The seat body 111 is suitable for moving relative to the base to transfer the workpiece to the working position. Specifically, the seat body 111 is fixedly connected to the multi-station turntable 3. When the multi-station turntable 3 rotates, the seat body 111 moves relative to the base so that the entire fixture 11 moves relative to the base. The connecting member 112 is rotatably connected to the base and is suitable for being detachably connected to the relay semi-finished product 5. The connecting member 112 is used to drive the workpiece to rotate. The rotation axis of the connecting member 112 is configured to coincide with the rotation axis of the workpiece; specifically, the connecting member 112 is provided with a stop portion 1121. The stop portion 1121 is suitable for being connected to the workpiece so that the connecting member 112 drives the workpiece to rotate. The stop portion 1121 is manifested as a groove or a protrusion to correspond to the stop surface 512 on the workpiece. In this embodiment, the stop The rotating part 1121 is a protrusion, and the back side of the relay semi-finished product 5 includes a stop surface 512. The side surface of the stop surface 1121 abuts against the stop surface 512 to achieve a stop fit. When there are two stop surfaces 512 or annular surfaces on the workpiece, the stop part 1121 can also be correspondingly mounted on the protrusion or inserted into the groove to achieve support for the product; wherein the two stop surfaces 512 are respectively formed by two facing or opposite surfaces of a square protrusion or groove, and the annular surface is formed by the wall of a cylindrical protrusion or groove.

[0075] In the present embodiment, there is only one anti-rotation surface 512 on the relay semi-finished product 5, which cannot provide support. In the present embodiment, the connecting member 112 also includes a fixing portion 1122, which is used to support the relay semi-finished product 5. Specifically, the fixing portion 1122 includes two fixing plates 11221 spaced apart from each other, and the fixing portion 1122 is suitable for being inserted into the hole of the workpiece and reducing the interval between the two fixing plates 11221. The two fixing plates 11221 are pressed against the hole wall of the workpiece under the action of their respective reset forces to fix the workpiece; in the present embodiment, the fixing portion 1122 is inserted into the core hole 511 to support the relay semi-finished product 5, and increase the assembly force of the relay semi-finished product 5 on the fixing portion 1122 to prevent the relay semi-finished product 5 from being easily detached.

[0076] The connecting member 112 is further provided with a first matching portion 1123 and a second matching portion 1124, both of which are located at one end of the connecting member 112 along its rotation axis and away from the fixed portion 1122, and the first matching portion 1123 is represented by a rotation-stopping groove 11231, both ends of which extend to the circumference of the connecting member 112. The second matching portion 1124 is represented by a plurality of arc-shaped grooves opening on the circumference of the connecting member 112 and extending in the direction of its rotation axis.

[0077] The top block 113 is used to lock or unlock the rotation of the connecting member 112. The top block 113 slides relative to the base body 111 in a direction intersecting the rotation axis between a first position and a second position. In this embodiment, the top block 113 slides in the vertical direction.

[0078] The top block 113 is provided with a third engaging portion 1131 and a fourth engaging portion 1132. The third engaging portion 1131 and the first engaging portion 1123 face the same side away from the relay semi-finished product 5. The third engaging portion 1131 is presented as a first inclined surface, and the first inclined surface is an inclined surface that tilts towards the side of the relay semi-finished product 5.

[0079] The fourth engaging portion 1132 is presented as an arc-shaped protrusion adapted to the arc-shaped groove. The cooperation between the arc-shaped protrusion and the arc-shaped groove has a certain guiding effect. For small angular deviations, corresponding alignment can be achieved through the cooperation of the arc-shaped protrusion and the arc-shaped groove. And when the top block 113 moves to the first position, the fourth engaging portion 1132 and the second engaging portion 1124 achieve a rotation-stopping fit through insertion, thereby fixing the connecting member 112. At this time, the connecting member 112 cannot rotate. When the top block 113 moves to the second position and moves away from the second engaging portion 1124, the fourth engaging portion 1132 is disengaged from the insertion with the second engaging portion 1124, realizing unlocking, thereby allowing the connecting member 112 to rotate.

[0080] The reset member 114 is located between the transfer member and the top block 113 to apply an elastic force to the top block 113 to keep it in the first position, so that the top block 113 automatically resets to the locked state. In this embodiment, the reset member 114 is a spring.

[0081] Reference Figure 6 As shown in the figure, the driving device 12 includes a first driving member 121, a second driving member 122 and a pushing block 123. The first driving member 121 is fixedly connected to the position of the base near the working position. The first driving member 121 is used to drive the second driving member 122 and the pushing block 123 to move along the rotation axis direction of the workpiece at the working position, so that the output end of the second driving member 122 moves towards the connecting member 112 and establishes a rotation-stopping fit relationship with the first engaging portion 1123. In this embodiment, the output end of the second driving member 122 is a rotation-stopping convex block adapted to the rotation-stopping groove 11231. And the pushing block 123 also slides towards the top block 113 until it drives the top block 113 to move to the second position by cooperating with the inclined surface of the third engaging portion 1131, overcoming the elastic force of the reset member 114. Through the action of the inclined surface, a force with a vertical downward component is applied to the top block 113, so that the top block 113 can move to the second position. At this time, the second driving member 122 can drive the connecting member 112 to drive the workpiece to rotate.

[0082] When the first driving member 121 drives the second driving member 122 and the pushing block 123 to slide in a direction away from the fixture 11, the output end of the second driving member 122 and the pushing block 123 are disengaged from the fixture 11, so that the fixture 11 can continue to be transferred with the multi-station turntable 3 without interference with the driving device 12. At this time, under the action of the reset member 114, the top block 113 automatically resets to the locked state, and during the process of the fixture 11 continuing to be transferred with the multi-station turntable 3, the connecting member 112 will not rotate.

[0083] The first driving member 121 drives the second driving member 122 and the pushing block 123 to slide simultaneously, which saves more energy compared to the second driving member 122 and the pushing block 123 sliding independently. And the driving device 12 only needs to be set at the corresponding station, without corresponding to the fixture 11 one by one, saving costs.

[0084] In this embodiment, according to the setting of the station timing, they are successively the feeding mechanism, the first detection mechanism, the second detection mechanism, the third detection mechanism, the fourth detection mechanism, the fifth detection mechanism, the line scan detection mechanism 2, the sixth detection mechanism, the OK product discharging mechanism 4, and the NG product discharging mechanism, so as to realize automatic detection and production.

[0085] In the existing relay detection mechanism, most are for the appearance detection of finished products, and there is little detection of semi-finished products. However, through testing, whether there are dirt and soldering on the appearance of the coil 52; the soldering condition of the pins 53; the injection molding condition of the base body 51; the insertion condition of the base body 51 and the pins 53; whether the feet are perpendicular to the back surface of the base body 51 and the diameter of the coil 52 will all affect the service life and usage of the final product. The above-mentioned missed detections will lead to problems such as poor conductivity or vulnerability of the final product. However, in the appearance detection of finished products, the above-mentioned appearances cannot be detected.

[0086] The feeding mechanism is used to install the relay semi-finished product 5 to be detected on the fixture 11 at the feeding station and make the anti-rotation surface 512 and the anti-rotation part 1121 be in anti-rotation cooperation, and the fixing part 1122 is inserted into the iron core hole 511, so as to realize the installation of the relay to be detected. The feeding mechanism can be a manipulator.

[0087] Reference Figures 12-15 , since in the previous process, the pins 53 need to be inserted into the tin solution for tin plating, therefore, when initially entering this detection device, the two pins 53 face downward, and the opening of the stripping groove 513 on the circumferential surface of the base body 51 faces upward.

[0088] The first detector is adapted to obtain the front image of the base body 51 to detect the injection molding condition of the base body 51, ensure that there is no white edge on the base body 51, so as to ensure the strength of the base body 51. The mainly obtained image is Figure 11 The dotted line part.

[0089] The second detection mechanism is suitable for obtaining the back image of the base body 51 to detect the insertion condition of the base body 51 and the pins 53, so as to prevent the pins 53 from falling off in the subsequent process; the main image obtained is Figure 12 the dotted line.

[0090] The third detection mechanism is suitable for obtaining the top image of the base body 51 to detect whether the base body is deformed and the identification of the base body 51 to prevent material mixing, so as to prevent assembly problems caused by product deformation in the subsequent process and prevent interference with the OK product blanking mechanism 4 caused by material mixing; such as Figure 13 the whole of the relay semi-finished product 5 in

[0091] The fourth detection mechanism is suitable for obtaining the top image of the base body 51 to detect the soldering condition of the pins 53 at the top, so as to prevent poor conductivity; the main image obtained is Figure 13 the dotted line.

[0092] The fifth detection mechanism is suitable for obtaining the bottom image of the base body 51 to detect the soldering condition of the pins 53 at the bottom, so as to prevent poor conductivity;

[0093] The line scan detection mechanism 2 includes a line scan camera. The receiving light of the line scan camera is perpendicular to the rotation axis of the relay semi-finished product 5 when it is at the line scan station. The line scan camera is suitable for obtaining the full-circle image of the relay semi-finished product 5 driven by the second driving member 122 to drive the connecting member 112 and drive the relay semi-finished product 5 to rotate, so as to detect the appearance of the coil 52 of the relay semi-finished product 5, so as to prevent problems such as dirt on the appearance of the coil 52, soldering leading to poor conductivity or vulnerability of the final product.

[0094] The sixth detection mechanism is suitable for obtaining the top image of the base body 51 to detect whether the two pins 53 are perpendicular to the back surface of the base body 51 and the diameter of the coil 52, so as to prevent the pins 53 from bending and breaking during subsequent assembly and prevent the coil 52 from being wound more or less, resulting in different magnetic fluxes of the same product; such as Figure 14

[0095] After the above detection mechanism transmits the obtained image to be measured to the computer, the computer performs contour grabbing, measurement of the data to be measured or comparison with the OK product image on the image to be measured, and draws a conclusion on whether the relay semi-finished product 5 is an OK product or an NG product. The means of detecting the appearance are similar to those for detecting surface defects of objects in the prior art, and will not be elaborated here.

[0096] Reference Figures 7-10 ​, the OK product blanking mechanism 4 is adapted to blank the relay semi-finished product 5 when the appearance of the relay semi-finished product 5 is judged to be OK; the OK product blanking mechanism 4 includes a first moving member 41, a second moving member 42, a transfer plate 43 and a third moving member 44; the first moving member 41 is adapted to drive the second moving member 42 to move along the rotation axis direction of the relay semi-finished product 5 located at the OK product blanking station; the transfer plate 43 is provided with a seating surface 431 and a blanking convex block 432 protruding from the seating surface 431, a first guide plate 433, a second guide plate 434 and a limiting plate 435. The first guide plate 433 and the second guide plate 434 are arranged at intervals facing each other and are respectively used to block the left and right movement of the relay semi-finished product 5 relative to the transfer plate 43. The limiting plate 435 and the blanking convex block 432 are arranged at intervals facing each other and are respectively used to block the front and back movement of the relay semi-finished product 5 relative to the transfer plate 43. The second moving member 42 is adapted to drive the transfer plate 43 to move relative to the relay semi-finished product 5 in the vertical direction to a third position; at the third position, the seating surface 431 is for the relay semi-finished product 5 to seat and the blanking convex block 432 is inserted into the blanking groove 513, so that a force for separating the relay semi-finished product 5 can be applied without the front end of the transfer plate 43 protruding from the relay semi-finished product 5, the transfer plate 43 is more material-saving, and since the front end of the transfer plate 43 does not need to protrude from the relay semi-finished product 5, the transfer plate 43 will not interfere with the connecting member 112 during the upward movement, preventing the risk of collision. The first moving member 41 is adapted to drive the second moving member 42 to move along this rotation axis direction and away from the jig 11 when the transfer plate 43 is at the third position, so that the blanking convex block 432 pushes the relay semi-finished product 5 out of the jig 11. By limiting the relay semi-finished product 5 in all directions through the blanking convex block 432, the first guide plate 433, the second guide plate 434 and the limiting plate 435, the relay semi-finished product 5 will only move horizontally during blanking, preventing the relay semi-finished product 5 from tilting relative to the transfer plate 43 during blanking, resulting in scratching the iron core hole 511 of the relay semi-finished product 5 or damaging the fixing part 1122. At the same time, it also positions the relay semi-finished product 5 after blanking for subsequent transfer, preventing the position from being uncertain due to inertia during separation, which is inconvenient for subsequent transfer. The OK product blanking mechanism 4 can wait below the workpiece in advance and only needs two steps of upward movement and backward movement to separate the workpiece. Compared with the manipulator, it requires fewer steps of upward movement (or forward movement), clamping and backward movement, has higher efficiency, and will not damage the workpiece.

[0097] In this embodiment, there are multiple stripping protrusions 432, each stripping protrusion 432 is arranged along the second direction perpendicular to the rotation axis and the vertical direction, and the number of the first guide plate 433, the second guide plate 434 and the limit plate 435 is adapted to the stripping protrusion 432, that is, one relay semi-finished product 5 corresponds to one first guide plate 433, one second guide plate 434, one limit plate 435 and one stripping protrusion 432; the third moving member 44 is suitable for driving the first moving member 41 to move along the second direction to switch each stripping protrusion 432 to correspond to the relay semi-finished product 5 of the OK product unloading station, so that multiple OK products can be collected and uniformly transferred to the OK product placement, saving energy. The transfer of the relay semi-finished product 5 at the OK product unloading mechanism 4 to the OK product placement can be achieved by the vertically moving manipulator clamping the relay semi-finished product 5 to separate it from the transfer plate 43 and then performing other movements.

[0098] The NG product unloading mechanism is suitable for unloading the relay semi-finished product 5 when the appearance of the relay semi-finished product 5 is judged to be NG. It can be a robot, and it can also have multiple unloading positions, so that multiple NG products can be collected and uniformly transferred to the NG product placement area to save energy.

[0099] In this embodiment, there are two drive devices 12, namely, the first drive device 12 and the second drive device 12. The first drive device 12 is set corresponding to the station of the third detection mechanism to drive the connecting piece 112 corresponding to the station to rotate and drive the relay semi-finished product 5 to rotate so that the mark faces upward, which is 90 degrees in this embodiment. At this time, the soldering part of one pin 53 faces upward, and the soldering part of the other pin 53 faces downward. By rotating the first drive device 12 90 degrees, the cameras of most subsequent stations can obtain corresponding images by shooting from the top and bottom, without shooting from the left and right sides, which will cause interference with the multi-station turntable 3, making it impossible to arrange the camera.

[0100] The second driving member 122 is provided corresponding to the line scanning station and is configured to drive the connecting member 112 corresponding to the station to rotate 360° and then continue to rotate so that the opening of the stripping groove 513 on the peripheral surface of the base 51 faces downward, thereby preventing the OK product unloading mechanism 4 from interfering with the semi-finished product relay. In this embodiment, the total rotation is 450°.

[0101] The timing of the sensor is before the timing corresponding to the OK product discharging mechanism 4 and after the timing corresponding to the sixth detection mechanism. The sensor detects the distance from the anti-rotation groove 11231 to detect whether the opening of the material discharging groove 513 on the circumferential surface of the base body 51 faces downward, and emits a warning signal when the opening of the material discharging groove 513 on the circumferential surface of the base body 51 does not face downward. Specifically, in this embodiment, the sensor emits a laser beam vertically, and when the laser beam emitted by the sensor passes through the anti-rotation groove 11231, the opening of the material discharging groove 513 of the relay semi-finished product 5 on the circumferential surface of the base body 51 faces downward. When the laser beam penetrates the anti-rotation groove 11231 (the two ends of the anti-rotation groove 11231 extend to the circumferential surface of the connecting member 112, so the laser beam can penetrate), the detected distance is to other objects, and the distance is relatively large. When the connecting member 112 rotates incorrectly, the laser beam irradiates the circumferential surface of the connecting member 112 or the groove wall of the anti-rotation groove 11231, and the distance is relatively small. Therefore, by setting the interval of the detected distance, the attitude of the connecting member 112 at this time can be known, and thus the attitude of the material discharging groove 513 can be known.

[0102] The controller is electrically connected to the sensor and the alarm. When receiving the warning signal, it controls the alarm to give an alarm and suspends the detection device, so as to prevent the OK product discharging mechanism 4 from hitting the product and causing damage.
