Abstract
Description
Technical Field
[0001] This utility model relates to the field of product testing technology, and in particular to a turntable module and testing device. Background Technology
[0002] In the mechanical manufacturing process, the manufactured workpieces need to be inspected to remove defective products. The turntable module, with its compact structure, plays a role in the handling of workpieces during inspection.
[0003] In the turntable module of the related technology, multiple vacuum suction heads are arranged circumferentially on the turntable. Each vacuum suction head is controlled by an independent air path control structure. During the rotation of the turntable, the vacuum suction head can pick up the workpiece and move the workpiece to the defective product storage module and the good product storage module. The vacuum state of the vacuum suction head is controlled by the corresponding air path control structure so that the vacuum suction head can place the picked-up workpiece in the defective product storage module or the good product storage module.
[0004] However, since each vacuum nozzle requires an independent air path control structure, the number of air path control structures is relatively large. Each air path control structure has two states: air supply and vacuum maintenance. This makes the control of the entire rotary module more complex, and the response speed of the rotary module is relatively low. As a result, the rotation speed of the rotary disk in the existing rotary module is relatively low, which affects the working efficiency of the entire rotary module. Utility Model Content
[0005] The purpose of this invention is to at least solve one of the technical problems existing in the prior art. The first aspect of this invention provides a turntable module with higher working efficiency. The second aspect of this invention also provides a detection device.
[0006] According to a first aspect embodiment of the present invention, a turntable module includes a frame, a driver, and multiple suction heads. The frame includes a first frame and a second frame. The first frame has a first contact surface. The first frame contains a first air passage and multiple second air passages. One end of the first air passage extends to the first contact surface, and the other end of the first air passage is used to communicate with a vacuum generator. One end of each second air passage extends to the first contact surface, and the other end of the second air passage is used to communicate with an air path control structure. The second frame is rotatably connected to the first frame, and the second frame has a connection to the first air passage. A second contact surface is attached to the first contact surface. The second frame is provided with multiple third air channels. Each third air channel has a first air hole and a second air hole. The first air hole is located on the second contact surface. Multiple suction heads are located on the second frame and are circumferentially spaced around the rotation axis of the second frame. Each suction head corresponds to and is connected to the second air hole. The driver is connected to the second frame and can drive the second frame to rotate relative to the first frame so that the first contact surface closes the first air hole, or connects the first air channel to the first air hole, or connects the second air channel to the first air hole.
[0007] The turntable module of this utility model has at least the following beneficial effects: In the turntable module of this application, the first air channel is connected to the vacuum generator, and the second air channel is connected to the air path control structure. Under the drive of the driver, the second frame rotates relative to the first frame. When the first air hole of the third air channel is connected to the first air channel, a vacuum is generated inside the suction head connected to the third air channel under the action of the vacuum generator. The suction head adsorbs the workpiece. Under the drive of the driver, the second frame continues to rotate, the first contact surface seals the first air hole, the suction head remains in a vacuum state, and continues to adsorb the workpiece. When the second frame rotates to the point where the first air hole is connected to the second air channel, the air path control structure can adjust according to the actual situation. The system allows for selection of whether to disrupt the vacuum environment inside the suction head. When the workpiece adsorbed by the suction head needs to be unloaded, the air path control structure can disrupt the vacuum environment inside the suction head to allow the workpiece to detach from the suction head and thus unload it. When the workpiece adsorbed by the suction head does not need to be unloaded, the air path control structure does not disrupt the vacuum environment inside the suction head, and the suction head can still maintain adsorption of the workpiece. Therefore, in the turntable module of this application, only a few air path control structures connected to the second air passage need to be controlled, thereby increasing the response speed of the turntable module of this application, allowing the second frame to rotate faster, and thus improving the working efficiency of the turntable module of this application.
[0008] According to the turntable module described in this embodiment of the present invention, an arc-shaped air groove is provided on the first contact surface. The curvature center of the air groove is located on the rotation axis of the second frame. The first air passage is connected to the air groove. The frame also includes a plurality of transition structures that are arranged one-to-one with the second air passages. The transition structure is detachably disposed in the air groove. A transition channel is formed in the transition structure. One end of the transition channel is connected to the corresponding second air passage, and the other end of the transition channel is used to connect to the first air hole.
[0009] According to the turntable module described in this embodiment of the present invention, the air groove has a connecting structure at one end in its extending direction.
[0010] According to the turntable module described in this embodiment of the present invention, the transfer structure includes a floating sealing block and a first elastic connector. The floating sealing block is provided with a third abutting surface for fitting with the second abutting surface. The transfer channel is located inside the floating sealing block and extends to the third abutting surface. The first elastic connector is connected to the floating sealing block and the first frame respectively. The first elastic connector is used to provide elasticity to keep the third abutting surface fitted with the second abutting surface.
[0011] According to the turntable module described in this embodiment of the present invention, the floating sealing block has a mounting hole at one end away from the third contact surface, and the first elastic connecting member is a spring, with the spring portion passing through the mounting hole.

The first rotating member is buoyantly disposed in the vertical direction. The first abutting surface and the second abutting surface are respectively disposed at the ends of the first frame and the first rotating member that are close to each other. The second elastic connector is connected to the first rotating member and the second rotating member respectively, and is used to provide elastic force to keep the second abutting surface abutting against the first abutting surface.
[0013] According to the turntable module described in this embodiment of the present invention, the suction head is disposed on the second rotating component, and the suction head is connected to the second air hole through a flexible air tube.
[0014] According to the turntable module described in this embodiment of the present invention, the first rotating member and the second rotating member are respectively provided with a first receiving groove and a second receiving groove, and the two opposite ends of the second elastic connecting member are respectively received in the first receiving groove and the second receiving groove.
[0015] The detection device provided according to the second aspect of the present invention includes the turntable module provided in the first aspect of the present invention.

The driver can drive the second frame to rotate so that the suction head moves sequentially to the feeding module, the detection module, the defective product storage module, and the good product storage module. When the suction head is located at the feeding module, the first air channel can communicate with the first air hole. When the suction head is located at the defective product storage module, the first air hole communicates with one of the second air channels.

[0032] The following is for reference. Figures 1 to 5 The turntable module of the first aspect of this application will be described in detail.
[0033] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5According to a first aspect embodiment of the present invention, a turntable module includes a frame 100, a driver 200, and multiple suction heads 300. The frame 100 includes a first frame 110 and a second frame 120. The first frame 110 has a first contact surface 111. The first frame 110 is provided with a first air passage 112 and multiple second air passages 113. One end of the first air passage 112 extends to the first contact surface 111, and the other end of the first air passage 112 is used to communicate with a vacuum generator. One end of the second air passage 113 extends to the first contact surface 111, and the other end of the second air passage 113 is used to communicate with an air path control structure. The second frame 120 is rotatably connected to the first frame 110, and the second frame 120 is provided with a first contact surface 111. The second abutment surface 121a is in contact with the abutment surface 111. The second frame 120 is provided with multiple third air passages 121b. The third air passages 121b have a first air hole and a second air hole. The first air hole is located on the second abutment surface 121a. Multiple suction heads 300 are provided on the second frame 120. The multiple suction heads 300 are circumferentially distributed around the rotation axis of the second frame 120. Each suction head 300 corresponds to and is connected to a second air hole. The driver 200 is connected to the second frame 120. The driver 200 can drive the second frame 120 to rotate relative to the first frame 110 so that the first abutment surface 111 closes the first air hole, or connects the first air passage 112 to the first air hole, or connects the second air passage 113 to the first air hole.
[0034] It should be noted that when the turntable module is working, the suction head 300 on the turntable module needs to pick up the workpiece from the feeding module, transfer the workpiece to the detection module for detection, and then move the workpiece sequentially to the defective product storage module and the good product storage module. If the detection module detects the workpiece as defective, the suction head 300 will discard the workpiece into the defective product storage module. If the detection module detects the workpiece as good, the suction head 300 will place the workpiece into the good product storage module. When the suction head 300 picks up the workpiece, a vacuum generator needs to create a vacuum inside the suction head 300 to enable the suction head 300 to pick up the workpiece. When the suction head 300 needs to discard the workpiece, the vacuum environment inside the suction head 300 needs to be broken. In order to improve the working efficiency of the turntable module, multiple suction heads 300 are often set on the turntable module. The system drives each suction head 300 to rotate synchronously, allowing them to sequentially cycle through the feeding module, detection module, defective product storage module, and good product storage module. However, different suction heads 300 are in different states; some are in a vacuum state, while others are in a devastated state. Consequently, it is difficult to simultaneously control all suction heads 300. Therefore, each suction head 300 requires a separate control structure. In this case, the excessive number of control structures makes the control of the entire turntable module complex. Consequently, during operation, in order to promptly control the corresponding suction head 300 to switch between vacuum and devastated states, the turntable module drives the suction head 300 to rotate at a slower speed, thus reducing the overall working efficiency of the turntable module.
[0035] It is understood that in the turntable module of this embodiment, under the drive of the driver 200, the second frame 120 rotates relative to the first frame 110, thereby causing the first air hole of the third air channel 121b to connect sequentially with the first air channel 112 and each of the second air channels 113. When the first air hole connects with the first air channel 112, since the first air channel 112 is connected to the vacuum generator, under the action of the vacuum generator, the corresponding suction head 300 is switched to a vacuum state through the third air channel 121b to adsorb the workpiece. When the driver 200 drives the second frame 120 to continue rotating relative to the first frame 110 so that the first air hole connects with the second air channel 113, at this time, since the second air channel 113 is connected to the air path control structure, the air path control structure can selectively disrupt the vacuum state of the corresponding suction head 300, so that the workpiece adsorbed by the suction head 300 falls off or the suction head 300 continues to hold the adsorbed workpiece. For example, in the application of the turntable module, the defective product storage module and the good product storage module can each correspond to a second air passage 113. The air path control structure connected to the second air passage 113 corresponding to the defective product storage module is the first air path control structure, and the air path control structure connected to the second air passage 113 corresponding to the good product storage module is the second air path control structure. When the suction head 300 is located at the feeding module, the third air passage 121b connected to the suction head 300 is connected to the first air passage 112. At this time, the suction head 300 is in a vacuum state, and the suction head 300 adsorbs the workpieces in the feeding module. When the driver 200 drives the first frame 110 to rotate, so that the suction head 300 moves to the defective product storage module, the suction head 300 and the defective product storage module... The second air passage 113 is connected. If the workpiece adsorbed by the suction head 300 is a defective product, the first air path control structure breaks the vacuum state of the suction head 300 through the second air passage 113, so that the workpiece adsorbed by the suction head 300 falls into the defective product storage module. If the workpiece adsorbed by the suction head 300 is a good product, the first air path control structure does not work, and the suction head 300 remains in a vacuum state. When the driver 200 drives the second frame 120 to rotate, so that the suction head 300 moves to the good product storage module, the second air passage 113 corresponding to the good product storage module is connected to the suction head 300. The second air path control structure breaks the vacuum state of the suction head 300 through the second air passage 113, so that the workpiece adsorbed by the suction head 300 falls into the good product storage module.
[0036] It is understandable that in the turntable device of this application, since the number of second air passages 113 is relatively less than the number of suction heads 300, the number of air path control structures can be reduced accordingly. Each air path control structure can switch the state of its corresponding suction head 300 more quickly, thereby increasing the rotation speed of the second frame 120 driving the suction head 300 to improve the working efficiency of the entire turntable module.
[0037] In some embodiments of this utility model, reference is made to Figure 3 The first contact surface 111 is provided with an arc-shaped air groove 114. The curvature center of the air groove 114 is located on the rotation axis of the second frame 120. The first air passage 112 is connected to the air groove 114. The frame 100 also includes a plurality of transition structures 130 that are arranged one-to-one with the second air passage 113. The transition structure 130 is detachably disposed in the air groove 114. A transition channel 131a is formed in the transition structure 130. One end of the transition channel 131a is connected to the corresponding second air passage 113, and the other end of the transition channel 131a is used to connect to the first air hole.
[0038] It is understandable that by setting an arc-shaped air groove 114, and the air groove 114 being connected to the first air channel 112, when the driver 200 drives the second frame 120 to rotate, the first air hole can always be connected to the air groove 114 when it can move between two adjacent transition structures 130, thereby filling the vacuum of the suction head 300, reducing the probability of the vacuum state of the suction head 300 being destroyed due to air leakage. Furthermore, when the suction head 300 is connected to the transition channel 131a of each transition structure 130, the suction head 300 is in a vacuum state, ensuring that the air path control structure can accurately control whether the workpiece adsorbed by the suction head 300 falls by controlling the vacuum state of the suction head 300.
[0039] In some embodiments of this utility model, reference is made to Figure 3 The air groove 114 has a transition structure 130 at one end of its extension direction.
[0040] Furthermore, one of the adapter structures 130 is located at one end of the air groove 114 in its own extension direction. Thus, when the turntable module of this application is used, the adapter structure 130 located at the end of the air groove 114 can correspond to the good product storage module. When the suction head 300 is located at the good product storage module, the first air hole corresponding to the suction head 300 is connected to the adapter channel 131a of the adapter structure 130 located at the end of the air groove 114. At this time, the suction head 300 can break its own vacuum state under the action of the gas control structure. Under the drive of the driver 200, the second frame 120 continues to rotate so that the first air hole corresponding to the suction head 300 is disengaged from the air groove 114. Afterwards, under the drive of the second frame 120, the suction head 300 can move again to the air groove 114 connected to the corresponding first air hole for the next workpiece handling.
[0041] It is understandable that by placing one of the adapter structures 130 at one end of the air groove 114 in its own extending direction, the vacuum state inside the suction head 300 can be broken after the suction head 300 rotates until the corresponding first air hole is disengaged from the air groove 114, thereby reducing the probability that the first air hole adsorbs the first contact surface 111, so that the second frame 120 can rotate with less resistance relative to the first frame 110.
[0042] In some embodiments of this utility model, reference is made to Figure 4 The transition structure 130 includes a floating sealing block 131 and a first elastic connector 132. The floating sealing block 131 is provided with a third abutting surface 131b for abutting with the second abutting surface 121a. The transition channel 131a is located inside the floating sealing block 131 and extends to the third abutting surface 131b. The first elastic connector 132 is connected to the floating sealing block 131 and the first frame 110 respectively. The first elastic connector 132 is used to provide elasticity to keep the third abutting surface 131b abutting with the second abutting surface 121a.
[0043] It should be noted that if there is a gap between the third contact surface 131b and the second contact surface 121a, when the transfer channel 131a is connected to the first air hole, even if the gas control structure breaks the vacuum inside the suction head 300, because the air groove 114 is connected to the vacuum generator, under the action of the vacuum generator, the gas inside the suction head 300 will enter the air groove 114 through the gap between the third contact surface 131b and the second contact surface 121a, thereby increasing the vacuum inside the suction head 300, which is not conducive to the drop of the workpiece adsorbed by the suction head 300.
[0044] Understandably, under the elastic force of the first elastic connector 132, the third abutting surface 131b can approach and fit against the second abutting surface 121a, thereby reducing the probability of a gap between the third abutting surface 131b and the second abutting surface 121a. When the transfer channel 131a and the first air hole are connected, the gas control structure can successfully disrupt the vacuum environment inside the suction head 300.
[0045] Understandably, during the rotation of the second frame 120, wear will occur between the second frame 120 and the floating sealing block 131, resulting in a gap between the second abutment surface 121a and the third abutment surface 131b. The first elastic connector 132 ensures that even if a gap occurs between the second abutment surface 121a and the third abutment surface 131b, the floating sealing block 131 will always remain in close contact with the second abutment surface 121a, thus ensuring that the third abutment surface 131b always remains in contact with the second abutment surface 121a, thereby reducing the probability of a gap forming between the second abutment surface 121a and the third abutment surface 131b.
[0046] In some embodiments of this utility model, reference is made to Figure 4 The floating sealing block 131 has a mounting hole 131c at one end away from the third abutment surface 131b, and the first elastic connector 132 is a spring, with the spring part passing through the mounting hole 131c.
[0047] It is understandable that the spring has a simple structure and is easy to obtain; by setting a mounting hole 131c on the floating sealing block 131 and inserting the spring part into the mounting hole 131c, the probability of the spring shifting during operation can be reduced.
[0048] In some embodiments of this utility model, the second frame 120 includes a first rotating member 121, a second rotating member 122, and a second elastic connector 123. The first rotating member 121 is buoyant in the vertical direction. The first abutting surface 111 and the second abutting surface 121a are respectively located at the ends of the first frame 110 and the first rotating member 121 that are close to each other. The second elastic connector 123 is connected to the first rotating member 121 and the second rotating member 122 respectively, and is used to provide an elastic force that keeps the second abutting surface 121a abutting against the first abutting surface 111.
[0049] For example, such as Figure 5 As shown, the second frame 120 includes a first rotating member 121, a second rotating member 122, and a second elastic connecting member 123. The first rotating member 121 is located on the upper side of the second rotating member 122 and on the lower side of the first frame 110. The first abutting surface 111 is located on the lower end surface of the first frame 110, and the second abutting surface 121a is located on the upper end surface of the first rotating member 121. The second elastic connecting member 123 is located between the first rotating member 121 and the second rotating member 122, and the upper and lower ends of the first elastic connecting member 123 are respectively connected to the first rotating member 121 and the second rotating member 122.
[0050] Understandably, during prolonged operation of the second frame 120, wear will occur between the second abutment surface 121a and the first abutment surface 111, resulting in a large gap between them. Under these circumstances, it is difficult for the air groove 114 to maintain a vacuum state for a long time. By configuring the second frame 120 as a first rotating member 121 and a second rotating member 122, under the action of the second elastic connector 123, the first rotating member 121 can always abut against the first frame 110 upwards. Thus, even if a large gap occurs between the first abutment surface 111 and the second abutment surface 121a, the second elastic connector 123 can push the first rotating member 121 upwards, so that the second abutment surface 121a always fits tightly against the first abutment surface 111.
[0051] In some embodiments of this utility model, reference is made to Figure 5The suction head 300 is mounted on the second rotating member 122, and the suction head 300 is connected to the second air hole through the flexible air tube 310.
[0052] Understandably, the flexible air tube 310 ensures that even if the first rotating member 121 floats in the vertical direction under the action of the second elastic connector 123, the suction head 300 can still maintain stable communication with the second air hole through the flexible air tube 310.
[0053] In some embodiments of this utility model, the first rotating member 121 and the second rotating member 122 are respectively provided with a first receiving groove and a second receiving groove, and the two opposite ends of the second elastic connecting member 123 are respectively received in the first receiving groove and the second receiving groove.
[0054] It is understandable that the first and second receiving slots are designed so that the first receiving slot can cooperate with the second receiving slot to protect the second elastic connector 123. On the one hand, this can improve the overall structural compactness of the second frame 120, and on the other hand, it can improve the overall appearance of the second frame 120.
[0055] The detection device provided according to the second aspect of the present invention includes the turntable device provided in the first aspect of the present invention.
[0056] In some embodiments of this utility model, the detection device further includes a feeding module, a detection module, a defective product storage module, and a good product storage module. The feeding module is used to provide workpieces, the detection module is used to detect the workpieces, the defective product storage module is used to receive workpieces that are detected as defective, and the good product storage module is used to receive workpieces that are detected as good. The driver 200 can drive the second frame 120 to rotate so that the suction head 300 moves sequentially to the feeding module, the detection module, the defective product storage module, and the good product storage module. When the suction head 300 is located at the feeding module, the first air passage 112 can communicate with the first air hole. When the suction head 300 is located at the defective product storage module, the first air hole communicates with one of the second air passages 113. When the suction head 300 is located at the good product storage module, the first air hole communicates with the other of the second air passages 113.
