Abstract
Description
Technical Field
[0001] This utility model belongs to the field of watch manufacturing, and in particular relates to testing devices and watch manufacturing equipment. Background Technology
[0002] In the field of watch manufacturing and quality inspection, the assembly quality of the lugs is one of the key factors affecting the safety and user experience of wearing a watch. The lugs are protruding parts on both sides of the watch case used to connect the strap or bracelet. They typically have holes or grooves inside, with spring rods at both ends acting as connecting blocks. These springs must be precisely engaged into the lug holes to secure the strap or bracelet. The reliability of this connection directly determines whether the watch will accidentally fall off. The damping force of the lugs is a core indicator for evaluating this quality; therefore, it is necessary to test the torque of the lugs rotating relative to the watch case to obtain the damping force data.
[0003] Currently, testing different parameters of the lugs requires multiple testing devices with different testing functions. The existing testing method involves setting up multiple independent testing devices at different locations on the conveyor belt for separate testing. The arrangement of multiple testing devices along the extension direction of the conveyor belt results in an excessively large lateral space occupied by the entire testing device. Furthermore, the existing testing method usually uses suction cups to adsorb and position the test piece. The adsorption force of the suction cups is prone to fluctuation, which cannot effectively position the test piece. This causes the test piece to shake or shift during testing, thereby increasing the measurement deviation caused by the instability of the test piece's position. Utility Model Content
[0004] The purpose of this application is to provide a testing device and a watch manufacturing equipment, aiming to solve the problems of how to reduce the space occupied by the testing device and how to improve the accuracy of the testing device.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0006] In a first aspect, a testing apparatus is provided, comprising a frame, a turntable rotatably connected to the frame, a carrier disposed on the turntable, a detection structure for detecting a component to be tested, and a drive structure disposed on the frame and connected to the turntable. Multiple detection structures are arranged at intervals along the circumference of the turntable. The drive structure drives the turntable to rotate so that the carrier sequentially engages with each of the detection structures. The component to be tested includes multiple test parts, and each detection structure is used to detect each test part. The carrier includes a placement seat for carrying the component to be tested, a first clamping member disposed on the placement seat, and a second clamping member slidably disposed relative to the first clamping member along a preset direction and spaced apart from the first clamping member. The second clamping member is used to move toward the first clamping member to clamp the component to be tested together with the first clamping member.
[0007] In some embodiments, the carrier further includes a power member spaced apart from the placement seat along the preset direction, the second clamping member being connected to the output end of the power member, and the power member being used to drive the second clamping member to move along the preset direction, so that the second clamping member moves toward or away from the first clamping member.
[0008] In some embodiments, the carrier further includes a limiting block connected to the edge of the placement seat, wherein a plurality of limiting blocks are arranged at intervals along the circumference of the carrier, and the plurality of limiting blocks surround to form a limiting space for limiting the test object.
[0009] In some embodiments, the shape of the limiting space is adapted to the outer contour of the object to be tested.
[0010] In some embodiments, the limiting block has an abutting surface that abuts against the test piece, so that the abutting surface is adapted to the outer surface shape of the test piece.
[0011] In some embodiments, a buffer is provided on the contact surface between the second clamping member and the test piece. The buffer is made of a flexible material and is used to buffer the vibration generated when the second clamping member contacts the test piece.
[0012] In some embodiments, the power component includes a driver and a guide structure for the driver, the second clamping member is connected to the output end of the driver, and the guide structure is used to guide the second clamping member to slide along the preset direction.
[0013] In some embodiments, the guide structure includes a guide plate connected to the side of the second clamping member opposite to the placement seat and a guide rail connected to the driver. The guide rail extends along the preset direction, and the guide plate is provided with a sliding groove extending along the preset direction. The sliding groove is slidably connected to the guide rail.
[0014] In some embodiments, multiple carriers are arranged at circumferential intervals along the turntable, and the drive structure drives the turntable to rotate so that each carrier sequentially docks with each detection structure.
[0015] Secondly, a watch manufacturing apparatus is provided, which includes the testing device described above.
[0016] The beneficial effects of this application are as follows: When the testing device of this application is in use, the drive structure drives the turntable to rotate so that the carrier docks with each detection structure in sequence. Each detection structure is used to detect each component of the test piece, thereby realizing the testing of the test piece. By arranging multiple detection structures at intervals along the circumference of the turntable, compared with the straight layout that requires reserving a transmission path for the test piece for each detection structure, the turntable transmission method occupies less space and has a more compact structure, which is beneficial to reducing the space occupied by the testing device. Furthermore, during the testing process, the second clamping member moves toward the first clamping member to clamp the test piece together with the first clamping member, thereby realizing the positioning of the test piece. The positioning method is simple and is not affected by the fluctuation of the adsorption force, ensuring that the test piece does not shake or shift during the testing process, thereby improving the accuracy of the testing.

[0027] Please see Figures 1 to 3This application provides a testing device, including a frame 50, a turntable 20 rotatably connected to the frame 50, a carrier 10 disposed on the turntable 20, a detection structure 40 for detecting a test piece 200, and a drive structure 30 disposed on the frame 50 and connected to the turntable 20. Multiple detection structures 40 are arranged at intervals along the circumference of the turntable 20. The drive structure 30 is used to drive the turntable 20 to rotate so that the carrier 10 sequentially docks with each detection structure 40. The test piece 200 includes multiple test components 220, and each detection structure 40 is used to detect each test component 220. The carrier 10 includes a placement seat 13 for carrying the test piece 200, a first clamping member 11 disposed on the placement seat 13, and a second clamping member 12 that is slidably disposed relative to the first clamping member 11 along a preset direction a and spaced apart from the first clamping member 11. The second clamping member 12 is used to move toward the first clamping member 11 to clamp the test piece 200 together with the first clamping member 11.
[0028] In this embodiment, the detection structure 40 can be used to detect the damping force data of the component 200 to be tested. The component 200 to be tested includes a main body 210 and a test component 220 rotatably connected to the main body 210. In a specific embodiment, the component 200 to be tested is a watch, with the main body 210 and the test component 220 being the watch case and lugs, respectively. The lugs are protruding parts on both sides of the watch case used to connect the watch strap or bracelet. They are usually designed with holes or grooves inside. A spring rod acts as a connecting block, with compression springs at both ends, and needs to be precisely inserted into the lug holes to fix the watch strap or bracelet. Therefore, the testing device in this embodiment can detect the torque of the lugs rotating relative to the watch case, thereby obtaining the damping force of the lugs. This damping force is a core indicator for evaluating the assembly quality of the watch. Of course, in other possible embodiments, the main body 210 and the test component 220 can also be other structures that can rotate relative to each other. This embodiment does not limit the specific structure of the main body 210 and the test component 220.
[0029] In addition, since there may be multiple test components 220, for example, when the main body 210 and the test component 220 are the watch case and lugs of a watch respectively, there are two lugs, which are located on opposite sides of the watch case. In this case, there are two detection structures 40. The two testing devices are used to detect the damping force data of the two test components 220 connected to the same test component 200, and compare the damping force data of the two test components 220.
[0030] Understandably, in this embodiment of the application, the turntable 20 is a disc-shaped structure, the carrier 10 is set on the edge of the turntable 20, and multiple detection structures 40 are arranged in a ring array around the rotation center of the turntable 20.
[0031] In use, the testing device of this application drives the turntable 20 to rotate so that the carrier 10 sequentially docks with each detection structure 40. Each detection structure 40 is used to detect each component 220 of the test piece 200, thereby realizing the testing of the test piece 200. By arranging multiple detection structures 40 at intervals along the circumference of the turntable 20, compared with the linear layout that requires reserving a transmission path for the test piece 200 for each detection structure 40, the turntable 20 transmission method occupies less space and has a more compact structure, which is beneficial to reducing the space occupied by the testing device. In addition, during the testing process, the second clamping member 12 moves toward the first clamping member 11 to clamp the test piece 200 together with the first clamping member 11, thereby realizing the positioning of the test piece 200. The positioning method is simple and is not affected by the fluctuation of the adsorption force, ensuring that the test piece 200 does not shake or shift during the testing process, thereby improving the accuracy of the testing.
[0032] In addition, the entire system only requires one drive structure 30 to drive the transport of all the test pieces 200, which greatly simplifies the drive and control system. It does not require a complex linear conveyor belt system, multi-axis robotic arms or a large number of independent propulsion cylinders to transfer the test pieces 200 between multiple detection structures 40.
[0033] Optionally, the drive structure 30 may include a stepper motor, a reducer, and an indexing structure. The stepper motor provides precise angle control, controlling the rotation angle and speed by receiving pulse signals. The reducer is typically a planetary reducer or a worm gear reducer, which reduces the motor's output speed while significantly increasing the output torque to meet the requirements of driving the large inertia turntable 20, and also improves system rigidity and reduces vibration. The indexing mechanism is key to achieving precise indexing and positioning. Specifically, the indexing mechanism can be a cam divider, which uses a conjugate cam structure to convert the continuous rotational motion of the motor into intermittent precise indexing motion of the turntable 20. This results in extremely high positioning accuracy and repeatability, strong load-bearing capacity, good rigidity, smooth operation, and long service life. It is suitable for medium-to-high speed, high-precision, and heavy-load applications.
[0034] In some embodiments, such as Figure 1As shown, multiple carriers 10 are arranged at intervals along the circumference of the turntable 20. The drive structure 30 drives the turntable 20 to rotate so that each carrier 10 sequentially mates with each detection structure 40. Understandably, the multiple carriers 10 are arranged in a circular array around the rotation center of the turntable 20, and the positions of the multiple detection structures 40 correspond to the positions of the multiple carriers 10. The drive structure 30 controls the rotation of the turntable 20 so that the multiple carriers 10 sequentially mate with each detection structure 40. When the turntable 20 is in a certain position, after all the items to be tested 200 on all the carriers 10 corresponding to the detection structures 40 on the turntable 20 have been tested, the turntable 20 rotates to the next position, so that the carriers 10 on the turntable 20 mate with the detection structures 40 at the next position. Then, the detection structures 40 continue to test the items to be tested 200 on their corresponding carriers 10 until all carriers 10 have been sequentially tested. In this way, when each item 200 is being tested, the carrier 10 always holds the item 200 in place, eliminating the need for repeated handling and reducing the time spent on handling the item 200, thus improving the testing efficiency. Furthermore, when each testing structure 40 corresponds to a carrier 10, and each carrier 10 carries an item 200, all testing structures 40 can simultaneously test their corresponding items 200, avoiding interference between different testing structures 40 due to asynchronous testing.
[0035] In addition, by setting the first clamping member 11 and the second clamping member 12, the distance between the first clamping member 11 and the second clamping member 12 can be adjusted. Therefore, after the test piece 200 is placed on the placement seat 13, the second clamping member 12 slides toward the first clamping member 11 to clamp the test piece 200. When it is necessary to remove the test piece 200, the second clamping member 12 slides away from the first clamping member 11 to release the test piece 200.
[0036] In some embodiments, such as Figure 2 and Figure 3 As shown, the carrier 10 also includes a power component 14 spaced apart from the placement seat 13 along the preset direction a. A second clamping member 12 is connected to the output end of the power component 14. The power component 14 drives the second clamping member 12 to move along the preset direction a, causing the second clamping member 12 to move towards or away from the first clamping member 11. By incorporating the power component 14, manual intervention can be reduced, clamping efficiency improved, and clamping consistency ensured.
[0037] In some embodiments, such as Figure 2 and Figure 3As shown, the carrier 10 also includes limiting blocks 15 connected to the edge of the placement seat 13. Multiple limiting blocks 15 are arranged at intervals along the circumference of the carrier 10. The multiple limiting blocks 15 surround to form a limiting space for limiting the test piece 200. Therefore, the multiple limiting blocks 15 limit the test piece 200 from multiple directions, thereby improving the limiting effect of the test piece 200, making the position of the test piece 200 stable during the test, and thus improving the stability and accuracy of the test.
[0038] In some embodiments, the shape of the limiting space is adapted to the outer contour of the part to be tested 200, that is, multiple limiting blocks 15 are arranged to form a contoured cavity to accommodate the part to be tested 200. Since the contoured cavity closely matches the outer contour of the part to be tested 200, it provides a maximized contact area, eliminating the slight wobbling or rotational degrees of freedom that may exist in the part to be tested 200 during the positioning process. The simultaneous contact constraint of multiple complex curved surfaces can accurately and uniquely fix the part to be tested 200 in the expected position and orientation. In addition, the large contact area evenly distributes the positioning force across the entire contact surface. This greatly reduces the risk of local stress concentration and deformation of the part to be tested 200, significantly improves the rigidity of the entire carrier 10, and makes it less likely for the part to be tested 200 to undergo micro-displacement within the cavity.
[0039] Furthermore, the operator only needs to place the part to be inspected 200 into the shape-matching contour cavity, and it will automatically and quickly fall into the single correct position. This eliminates the need for tedious adjustments and alignment of multiple locating pins or reference surfaces, significantly reducing clamping time and lowering operational difficulty and error rates. Specifically, if the part to be inspected 200 has a ring-shaped structure, then multiple limiting blocks 15 form a ring array along the center of the part to be inspected 200.
[0040] In some embodiments, the limiting block 15 has an abutment surface 151 that abuts against the test piece 200. The abutment surface 151 is adapted to the shape of the outer surface of the test piece 200. Multiple abutment surfaces 151 simultaneously contact and constrain, which can accurately and uniquely fix the test piece 200 in the expected position and direction. Specifically, if the test piece 200 is a ring-shaped structure, then the abutment surface 151 is an arc-shaped surface adapted to the outer contour of the test piece 200.
[0041] In addition, a buffer 16 is provided on the contact surface between the second clamping member 12 and the test piece 200. The buffer 16 is made of a flexible material and is used to buffer the vibration generated by the contact between the second clamping member 12 and the test piece 200. The material of the buffer 16 can be Teflon, engineering plastic, or soft alloy, etc., to avoid hard contact between the second clamping member 12 and the test piece 200, thereby avoiding damage to the test piece 200.
[0042] In some embodiments, the power member 14 includes a driver 141 and a guide structure 142 for the driver 141. The second clamping member 12 is connected to the output end of the driver 141. The guide structure 142 is used to guide the second clamping member 12 to slide along a preset direction a, thereby preventing the movement direction of the second clamping member 12 from deviating and thus improving the positioning accuracy.
[0043] In some embodiments, the guide structure 142 includes a guide plate 1421 connected to the side of the second clamping member 12 facing away from the placement base 13 and a guide rail connected to the driver 141. The guide rail extends along a preset direction a, and the guide plate 1421 is provided with a groove extending along the preset direction a. The groove is slidably connected to the guide rail. By slidingly connecting the groove to the guide rail, the guide plate 1421 is guided, thereby guiding the second clamping member 12.
[0044] This utility model also proposes a watch production equipment, which includes a testing device. The specific structure of the testing device is as described in the above embodiments. Since this watch production equipment adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0045] In summary, when the testing device of this application is in use, the drive structure 30 drives the turntable 20 to rotate so that the carrier 10 sequentially docks with each detection structure 40. Each detection structure 40 is used to detect each component 220 of the test piece 200, thereby realizing the testing of the test piece 200. By arranging multiple detection structures 40 at intervals along the circumference of the turntable 20, compared with the linear layout that requires reserving a transmission path for the test piece 200 for each detection structure 40, the turntable 20 transmission method occupies less space and has a more compact structure, which is beneficial to reducing the space occupied by the testing device. Furthermore, during the testing process, the second clamping member 12 moves toward the first clamping member 11 to clamp the test piece 200 together with the first clamping member 11, thereby realizing the positioning of the test piece 200. The positioning method is simple and is not affected by the fluctuation of the adsorption force, ensuring that the test piece 200 does not shake or shift during the testing process, thereby improving the accuracy of the testing.
