Description

Technical Field

[0001] The present application relates to the field of non-standard detection, and specifically to a carrier rotation mechanism. Background Art

[0002] In the workpiece production line or test line, the process of the carrier rotating relative to the processing equipment or the testing equipment is often required. In order to save space and reduce manufacturing costs, in the prior art, a driver is provided at the workstation that needs to rotate to drive the carrier to rotate. In this process, meshing transmission between gears is often required.

[0003] On the one hand, when the carrier is transferred to the above-mentioned workstation, the gears need to mesh with each other. However, during the transfer process, the gears are in rigid contact with each other. When there is a deviation in the position of the two gears, that is, when the teeth of the two gears are in contact, the teeth and the gears need to be forced to rotate one of the gears by means of collision until the two gears mesh. Since this structure is used in the production line, the gears mesh and disengage frequently, and the gears are more easily damaged, affecting their service life. On the other hand, since the gears on the carrier and the gears on the motor need to mesh and disengage frequently, it is difficult to achieve dust-free processing, which makes it easier for impurities to adhere to the surface of the gears. When the two gears mesh and transmit, the impurities between the two will cause the gears to collide hard, causing serious damage to the gears. Summary of the invention

[0004] In order to solve the above technical problems, this application provides the following technical solutions:

[0005] The present application provides a carrier rotation mechanism, comprising:

[0006] A carrier transmission assembly, on which a driven gear is mounted;

[0007] The driving assembly comprises a base and a driving unit. The driving unit is provided with a driving gear. The driving gear and the driven gear are meshed with each other. The base and the driving unit are elastically connected.

[0008] In one embodiment, the driving unit includes a motor and a sliding seat, the motor is mounted on the sliding seat, and the base is slidably connected to the sliding seat;

[0009] An elastic module is arranged between the base and the sliding seat.

[0010] In one embodiment, a slide rail is installed on the bottom plate, a slider is installed on the sliding seat, and the slider is cooperatively connected with the slide rail.

[0011] In one embodiment, the base includes a bottom plate, the bottom plate is provided with an avoidance groove, and the motor is located in the avoidance groove.

[0012] In one embodiment, a stopper is installed on one end of the slide rail close to the carrier, and the sliding seat abuts against the stopper.

[0013] In one embodiment, there are at least two elastic modules, and the plurality of elastic modules are arranged on both sides of the motor.

[0014] In one embodiment, the carrier transmission assembly includes a transport module and a connecting seat, wherein the connecting seat is mounted on a movable end of the transport module, a carrier is rotatably connected to the connecting seat, and a driven gear is disposed on the carrier.

[0015] In one embodiment, the driving assembly is located below the carrier transmission assembly, the carrier is disposed on the top surface of the connecting seat, and the driving gear is disposed on the bottom surface of the connecting seat.

[0016] In one embodiment, the transport module is a multi-station turntable.

[0017] In one embodiment, the driving assembly further includes a detector for detecting a rotation angle of the driving gear.

[0018] This application has at least the following beneficial effects:

[0019] In the present application, the base and the driving unit are elastically connected. When the driving gear and the driven gear are engaged, if the tooth portion interferes with the gear, the driving gear can be offset relative to the driven gear. After the tooth portion of the driving gear passes over the interfering tooth portion, the driving unit is reset to complete the engagement of the driving gear and the driven gear, thereby reducing damage to the gears caused by collisions.

[0020] In addition, when the driving gear and the driven gear are transmitting, if there is a rigid collision between the driving gear and the driven gear, the base and the driving unit are elastically connected, and the driving gear can be offset relative to the driven gear. The elastic connection structure of the driving unit is used to buffer the impact force generated by the collision, thereby extending the working life of the gear. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0040] Reference Figure 1 , 2 As shown, in some embodiments of the present application, a carrier rotation mechanism is provided, including: a carrier transmission component 100 and a driving component 200, a driven gear 14 is installed on the carrier transmission component 100, specifically, the carrier transmission component 100 is used to transport multiple carriers 13, the carriers 13 are loaded with workpieces 15, and the carriers 13 are provided with driven gears 14.

[0041] Combination Figure 3As shown, the carrier transmission component 100 includes a transport module 11 and a connecting seat 12, and a plurality of connecting seats 12 are arranged and connected on the movable end of the transport module 11, and the transport module 11 can drive the connecting seat 12 to transfer. The transport module 11 can drive the connecting seat 12 to transfer to the inspection station. The carrier 13 is rotatably connected to the connecting seat 12, and the carrier 13 can rotate relative to the connecting seat 12, and the carrier 13 and the driven gear 14 follow. The driving component 200 includes a base 21 and a driving unit, and a driving gear 24 is installed on the driving unit. The base 21 and the driving unit are elastically connected. The elastic connection specifically means that the base 21 and the driving unit can move relative to each other and can be quickly reset.

[0042] The driving unit includes a motor 23 , and a driving gear 24 is mounted on the power output end of the motor 23 .

[0043] When the connecting seat 12 is transferred to the detection station, the carrier 13 approaches the driving assembly 200, and the driving gear 24 meshes with the driven gear 14. The motor 23 drives the carrier 13 to rotate relative to the connecting seat 12, so that the carrier 13 rotates, and then drives the workpiece 15 loaded on the carrier 13 to rotate. After the connecting seat 12 leaves the detection station, the driving gear 24 and the driven gear 14 are disengaged. On the one hand, compared with the detector rotating 360° around the workpiece, the detector of this solution does not move, and the rotation of the workpiece 15 can reduce the space required for rotation. On the other hand, compared with multiple detectors detecting the workpiece 15 from different angles, through the cooperation of the driving gear 24 on the motor 23 and the driven gear 14 on the carrier 13, only a single motor 23 is needed to drive the carrier 13 on any connecting seat 12 to rotate, reducing the use of the motor 23 and reducing the manufacturing cost.

[0044] In some embodiments of the present application, reference Figure 4 , 5 As shown, the driving unit further includes a sliding seat 22, the base 21 is slidably connected to the sliding seat 22, and the motor 23 is installed on the sliding seat 22. An elastic module 25 is arranged between the base 21 and the sliding seat 22. Under the traction of the elastic module 25, the sliding seat 22 is always kept close to the carrier 13 to ensure that the driving gear 24 is engaged with the driven gear 14, and the driving gear 24 drives the driven gear 14.

[0045] At the same time, during the process of the driving gear 24 and the driven gear 14 being in rigid contact, the driving gear 24 cooperates with the elastic module 25 and slides relatively through the sliding seat 22, driving the driving gear 24 away from the driven gear 14, so as to avoid the driving gear 24 and the driven gear 14 from colliding and damaging the gears. The elastic module 25 is elastically deformed when the driving gear 24 is away from the driven gear 14, and then elastically recovers to allow the driving gear 24 to re-engage with the driven gear 14.

[0046] It should be noted that the elastic deformation of the elastic module 25 requires a large force to ensure that the driving gear 24 and the driven gear 14 are difficult to separate when the driving gear 24 drives the driven gear 14. The elastic module 25 can be a common elastic element such as a tension spring or a compression spring.

[0047] In this solution, the base 21 includes a bottom plate 211, a slide rail 213 is installed on the bottom plate 211, and a slider 26 is installed on the slide seat 22, and the slider 26 is connected with the slide rail 213. The slide seat 22 is installed on the slider 26, so that the slide seat 22 can slide relative to the base 21.

[0048] In a specific embodiment, when the driving gear 24 is meshed with the driven gear 14, the elastic module 25 has a certain elastic deformation, and when the teeth of the driving gear 24 and the driven gear 14 interfere, the elastic deformation of the elastic module 25 is aggravated. Generally speaking, as the degree of deformation of the elastic element increases, the restoring force to overcome the deformation is also greater. Therefore, in the present application, when the driving gear 24 is meshed with the driven gear 14, the elastic module 25 maintains a certain deformation to prevent the driving gear 24 from being separated from the driven gear 14.

[0049] Furthermore, the sliding seat 22 on the slide rail 213 can move in a straight path close to the carrier 13 and away from the carrier 13. A stopper 212 is installed on one end of the slide rail 213 close to the carrier 13, and under the action of the elastic module 25, the sliding seat 22 often abuts against the stopper 212.

[0050] In the above embodiment, when the driving gear 24 is meshed with the driven gear 14, the elastic module 25 maintains a certain deformation, the driving gear 24 is pressed on the driven gear 14, and the teeth of the driving gear 24 are easily stuck in the groove between the two teeth on the driven gear 14, affecting the normal rotation of the driving gear 24 and the driven gear 14. In this solution, the sliding seat 22 abuts against the stopper 212 to limit the relative position of the driving gear 24 and the driven gear 14. That is, the driving gear 24 is ensured to be meshed with the driven gear 14, and the driving gear 24 and the driven gear 14 are prevented from being stuck.

[0051] Furthermore, there are at least two elastic modules 25, and the plurality of elastic modules 25 are disposed on both sides of the motor 23. In this solution, a connecting pile 27 is installed on the sliding seat 22, and the plurality of connecting piles 27 are disposed on both sides of the motor 23. A pile body corresponding to the connecting pile 27 is installed on the bottom plate 211, and both ends of the elastic module 25 are sleeved on the connecting pile 27 and the pile body, connecting the sliding seat 22 and the base 21 to form a relatively movable overall structure.

[0052] More specifically, the elastic restoring forces generated by the elastic modules 25 on both sides of the motor 23 are consistent or approximately consistent, and the elastic modules 25 on both sides of the motor 23 can maintain the sliding balance of the sliding seat 22. In this solution, the elastic deformation degree and elastic restoring forces generated by the elastic modules 25 on both sides are consistent, driving the reset speeds of both sides of the sliding seat 22 connected to the elastic modules 25 to be consistent, thereby ensuring that the sliding seat 22 moves smoothly on the slide rail 213. Exemplarily, the elastic module 25 can be a spring.

[0053] In some embodiments of the present application, Figure 2 3, one end of the connecting seat 12 is installed at the edge of the transport module 11, so that part of the connecting seat 12 extends out of the transport module 11, and the carrier 13 is arranged near the other end of the connecting seat 12. The driving assembly 200 is located below the carrier transmission assembly 100, the carrier 13 is arranged on the top surface of the connecting seat 12, and the driving gear 24 is arranged on the bottom surface of the connecting seat 12. The workpiece 15 is loaded on the carrier 13, and the workpiece 15 is located above the driven gear 14. In this solution, the detector (not shown) is located above the connecting seat 12, and there is no obstruction between the detector and the workpiece 15. After the carrier 13 rotates, the detector can completely detect the workpiece 15.

[0054] Exemplarily, the bottom plate 211 is provided with an avoidance groove 2111, and the motor 23 is located in the avoidance groove 2111. The motor 23 passes through the bottom plate 211, so that the motor 23 stands upright in the base 21.

[0055] In this solution, the transport module 11 can be a multi-station turntable. It should be noted that the transport module 11 includes but is not limited to a multi-station turntable, and the transport module 11 can also be a conveyor belt. The movable end of the transport module 11 is specifically a rotating disc or a moving material belt.

[0056] In some embodiments of the present application, the drive assembly 200 also includes a detector for detecting the rotation angle of the driving gear 24. In this solution, the detector includes an optical coupler and a sensor sheet. The sensor sheet is mounted on the output shaft of the motor 23, and the sensor sheet and the driving gear 24 are staggered to prevent the sensor sheet and the driven gear 14 from interfering with each other when the driving gear 24 and the driven gear 14 are in contact. The optical coupler is mounted on the sliding seat 22, and the sensor sheet can move relative to the optical coupler so that when the sensor sheet and the optical couple are inductively coupled, the output shaft rotates one circle. According to the detection signal of the detector, the motor 23 is controlled to work so as to intermittently drive the carrier 13 to rotate 360°, so as to facilitate comprehensive detection of the workpiece.

[0057] It should be pointed out that the detector includes but is not limited to photoelectric sensors, and the detector can also be a Hall sensor, a rotary encoder, and a mechanical electric shock sensor. Among them, the mechanical electric shock sensor specifically includes a turntable with a protrusion, the turntable is installed on the output shaft, and the mechanical electric shock sensor also includes a switch adapted to the protrusion. The turntable rotates one circle, so that the protrusion is pressed again on the switch, which is counted as one circle.

[0058] The above embodiments are used to further illustrate the present application, but the present application is not limited to these specific implementations. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be understood to be within the scope of protection of the present application.
