Description

Technical Field

[0001] This invention belongs to the field of watch testing technology, and particularly relates to drop testing devices and watch production lines. Background Technology

[0002] With the increasing popularity of smart wearable devices, the market share of watches (including smartwatches, sports watches, and traditional mechanical watches) continues to grow in the consumer electronics market. As everyday wearable devices, watches inevitably experience accidental drops and impacts during use, making their impact resistance and structural reliability key quality indicators. Currently, the industry typically uses drop tests to simulate the conditions under which products are dropped from different heights and angles during transportation, carrying, or use, in order to assess the watch's appearance damage, internal structural stability, and functional integrity.

[0003] However, most existing watch drop tests rely on manual operation, often using manual or semi-automatic methods. For example, a robotic arm holds the watch and lifts it to a specified height before releasing it, allowing the watch to fall freely onto a hard surface. This method has a low degree of automation, is not only inefficient but also prone to errors. Furthermore, it usually relies on visual analysis of the damage, which is highly subjective and results in incomplete data recording. Summary of the Invention

[0004] The purpose of this application is to provide a drop testing device and a watch production line, aiming to solve the problem of how to improve production efficiency.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, a drop test device is provided, comprising a detection mechanism, a release structure, a receiving platform disposed below the release structure and rotatably arranged around a preset axis, and a conveying structure located below the receiving platform. The release structure is used to drive material to move to a preset height and release the material so that the material undergoes free fall. The receiving platform has a first position state and a second position state. When the receiving platform is in the first position state, the receiving platform is located on the falling path of the material and receives the material. When the receiving platform is in the second position state, the receiving platform is angled to the conveying surface of the conveying structure so that the material on the receiving platform slides toward the conveying structure under the action of gravity. The conveying structure conveys the material to a preset position. The detection mechanism is used to acquire an image of the material at the preset position to detect the drop state of the material.

[0007] In some embodiments, the drop test device includes a drop box disposed between the release structure and the conveying structure, the drop box including a plurality of side plates connected in sequence, the plurality of side plates surrounding to form a drop channel for the material to pass through, and the receiving platform being rotatably connected to one of the side plates.

[0008] In some embodiments, one of the side plates has an avoidance groove extending along the direction of gravity to the edge of the side plate, the receiving platform is rotatably connected to the top wall of the avoidance groove, and the drop test device further includes a drive structure for driving the receiving platform to rotate, the drive structure being connected to the side plate with the avoidance groove and the drive structure being located on the side of the side plate away from the drop channel.

[0009] In some embodiments, the drop test device further includes a guide structure disposed on the conveying structure, the conveying structure having a collection area, the detection mechanism being able to collect images within the collection area, and the guide structure being used to guide the material to move to the collection area during the material conveying process.

[0010] In some embodiments, the release structure includes a linear moving mechanism and an adsorption mechanism slidably disposed on the linear moving mechanism. The linear moving mechanism is used to drive the adsorption mechanism to move in three-dimensional space, and the adsorption mechanism is used to adsorb or release the material.

[0011] In some embodiments, the drop testing device is provided with a loading station and a picking station along a preset direction. The drop testing device further includes a loading structure, which includes a sliding driver, a first loading mechanism for carrying the material, and a second loading mechanism located below the first loading mechanism for carrying the material. The first loading mechanism and the second loading mechanism are both slidably arranged along the preset direction. The release structure is located at the picking station. The sliding driver is used to drive the first loading mechanism and the second loading mechanism to slide back and forth between the loading station and the picking station. The first loading mechanism or the second loading mechanism receives the material to be tested at the loading station and transfers the material to the picking station. The release structure adsorbs the material at the picking station.

[0012] In some embodiments, the drop test apparatus further includes a material transfer structure, a first conveyor line spaced apart from the material transfer structure, and a second conveyor line spaced apart from the material transfer structure. The material transfer structure is used to pick up the tested and qualified material from the conveyor structure and transfer it to the first conveyor line. The material transfer structure is also used to pick up the tested and unqualified material from the conveyor structure and transfer it to the second conveyor line.

[0013] In some embodiments, a flipping structure is provided on the first conveyor line. The flipping structure includes a support seat that spans across the first conveyor line, a rotary driver connected to the support seat, and a gripping mechanism connected to the rotary driver. The material transfer structure releases the material to the gripping mechanism. The gripping mechanism is used to grip or release the material. The rotary driver is used to drive the gripping mechanism to rotate so that the material gripped by the gripping mechanism faces or turns away from the first conveyor line.

[0014] In some embodiments, the gripping mechanism includes a connecting frame connected to the rotary driver, a clamping driver connected to the connecting frame, and a clamping member slidably connected to the connecting frame. Two clamping members are spaced apart, and the clamping driver is used to drive the two clamping members to move towards each other or away from each other.

[0015] Secondly, a watch production line is provided, including the aforementioned drop testing device.

[0016] The drop testing device provided in this application, when the receiving platform is in the first position, the release structure drives the material to be tested to move to a preset height and releases the material. After release, the material undergoes free fall, and the receiving platform can catch the material. After catching the material, the receiving platform switches to the second position under the drive of the drive structure. Since the receiving platform is set at an angle to the conveying surface of the conveying structure, the material on the receiving platform slides towards the conveying structure under the action of gravity. The conveying structure conveys the material, and the detection mechanism detects the material on the conveying structure. The entire process, through the automatic coordination and operation of the release structure, receiving platform, drive structure, and detection mechanism, reduces manual operation and greatly improves the degree of automation. Moreover, after the material completes the drop, it can be automatically guided to the conveying structure immediately, and can flow to the detection position through the conveying structure without stopping, avoiding the material from staying at the drop position and affecting the testing of the next material. This allows the testing device to continuously perform drop tests at a very high rate, greatly improving production efficiency. Attached Figure Description

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] Please see Figures 1 to 7This application provides a drop test device, including a detection mechanism 40, a release structure 10, a receiving platform 20 disposed below the release structure 10 and rotatably arranged around a preset axis a, and a conveying structure 50 located below the receiving platform 20. The release structure 10 is used to drive the material 200 to move to a preset height and release the material 200 so that the material 200 can fall freely. The receiving platform 20 has a first position state and a second position state. When the receiving platform 20 is in the first position state, the receiving platform 20 is located on the falling path of the material 200 and receives the material 200. When the receiving platform 20 is in the second position state, the receiving platform 20 is set at an angle to the conveying surface of the conveying structure 50 so that the material 200 on the receiving platform 20 slides towards the conveying structure 50 under the action of gravity. The conveying structure 50 conveys the material 200 to the preset position. The detection mechanism 40 is used to collect an image of the material 200 at the preset position to detect the drop state of the material 200.

[0032] It should be noted that the material 200 in this embodiment is a watch. Understandably, as a daily wearable device, a watch will inevitably experience accidental drops, collisions, and other scenarios during use. Therefore, its impact resistance and structural reliability become key quality indicators. Thus, a drop test device can be used to test the watch's impact resistance and structural reliability.

[0033] In this embodiment, "preset height" refers to the vertical distance between the material 200 and the surface of the receiving platform 20 in its first position when the actuator lifts the material 200 and prepares to release it. Understandably, "preset height" is not a fixed value, but a parameter that can be preset and adjusted according to testing requirements. When testing materials 200 of different specifications and weights, different values ​​can be set for "preset height" to obtain comparable test results or simulate real-world usage scenarios.

[0034] In this embodiment, the drop test device further includes a drive structure 30 for driving the receiving platform 20 to rotate. By driving the receiving platform 20 to rotate through the drive structure 30, the receiving platform 20 can switch between a first position state and a second position state. Specifically, when the receiving platform 20 is in the first position state, the bearing surface of the receiving platform 20 extends in the horizontal direction, so it can smoothly receive the material 200 released by the release structure 10; while when the receiving platform 20 is in the second position state, the receiving platform 20 deflects toward the conveying surface of the conveying structure 50, and the conveying surface of the conveying structure 50 is parallel to the horizontal plane, so at this time the bearing surface of the receiving platform 20 is set at an acute angle to the horizontal plane.

[0035] Optionally, when the receiving platform 20 is in the second position, the angle between the receiving platform 20 and the conveying surface of the conveying structure 50 is in the range of 30° to 60°. Understandably, the angle between the receiving platform 20 and the conveying surface of the conveying structure 50 cannot be too large, otherwise the material 200 on the receiving platform 20 will slide towards the conveying structure 50 too quickly, causing damage to the material 200; conversely, the angle between the receiving platform 20 and the conveying surface of the conveying structure 50 cannot be too small, otherwise the weight of the material 200 will be insufficient to propel it towards the conveying structure 50.

[0036] Furthermore, the detection mechanism 40 in this embodiment can automatically acquire high-definition images of the material 200 after the drop test, and intelligently determine its drop state, such as damage, scratches, and structural separation, through image analysis technology, thereby replacing inefficient and subjective manual visual inspection. Optionally, the detection mechanism 40 is a camera. In this embodiment, the preset position is a fixed physical position. When the material 200 is transported to this position, the camera detection mechanism 40 will be immediately triggered to acquire an image.

[0037] The drop test device provided in this application, when the receiving platform 20 is in the first position, the release structure 10 drives the material 200 to be tested to move to a preset height and releases the material 200. After release, the material 200 undergoes free fall, and the receiving platform 20 can catch the material 200. After catching the material 200, the receiving platform 20 switches to the second position under the drive of the drive structure 30. Since the receiving platform 20 is set at an angle to the conveying surface of the conveying structure 50, the material 200 on the receiving platform 20 slides towards the conveying structure 50 under the action of gravity. The conveying structure 50 then transports the material 200. The material 200 on the conveying structure 50 is then tested by the testing mechanism 40. The entire process is automated through the release structure 10, the receiving platform 20, the drive structure 30, and the testing mechanism 40, which reduces manual operation and greatly improves the degree of automation. After the material 200 completes the drop test, it can be automatically guided to the conveying structure 50 immediately. It can flow to the testing position through the conveying structure 50 without stopping, avoiding the material 200 from staying at the drop position and affecting the testing of the next material 200. This allows the testing device to continuously perform drop tests at a very high rate, which greatly improves production efficiency.

[0038] In addition, the receiving platform 20 is designed to switch between a horizontal receiving state and an inclined unloading state, which effectively utilizes vertical space. The conveying structure 50 is arranged below, so that the whole device integrates drop, receiving and conveying functions without the need for an additional mechanical transfer arm. The overall structure of the equipment is more compact and reliable, reducing manufacturing costs and failure rate.

[0039] Understandably, this application also includes a control system (not shown in the figure). The release structure 10, the receiving platform 20, the drive structure 30, and the detection mechanism 40 are all communicatively connected to the control system. The control system can control the release structure 10, the receiving platform 20, the drive structure 30, and the detection mechanism 40 to automatically coordinate and operate, thereby reducing the impact of human factors and improving production efficiency.

[0040] In some embodiments, such as Figures 1 to 3 As shown, the drop test device includes a drop box 60 located between the release structure 10 and the conveying structure 50. The drop box 60 includes a plurality of side plates 61 connected in sequence. The plurality of side plates 61 surround to form a drop channel 62 for the material 200 to pass through. The receiving platform 20 is rotatably connected to one of the side plates 61.

[0041] Understandably, multiple side plates 61 surround to form a falling channel 62. The falling channel 62 forms two openings at the top and bottom of the drop box 60, respectively. The upper opening corresponds to the release structure 10. The release structure 10 releases the material 200 from the upper opening of the drop box 60. The falling channel 62 provides a controlled, closed, and standardized environment for the free fall motion of the material 200, thereby isolating external interference and effectively isolating external airflow, personnel movement, and other accidental factors from interfering with the falling trajectory. This ensures that the watch will not accidentally deviate or rotate during the fall. Furthermore, the inner wall of the channel guides and constrains the posture of the material 200, enabling it to fall strictly according to the preset vertical path, thereby ensuring that the impact angle and the height of the force point are consistent during the test.

[0042] Furthermore, by rotatably connecting the receiving platform 20 to one of the side plates 61, the side plate 61 provides a sturdy and stable mounting base for the rotation of the receiving platform 20, avoiding the complexity of suspending the platform separately or setting up a separate support frame. This makes the overall structure more compact, rigid, and reliable in operation, reducing assembly difficulty and long-term maintenance costs. Optionally, the drop box 60 in this embodiment is rectangular. Of course, in other possible implementations, the drop box 60 can also be other shapes. This embodiment does not limit the specific shape of the drop box 60.

[0043] In some embodiments, such as Figure 2 and Figure 4 As shown, one of the side plates 61 has a clearance groove 63, which extends along the direction of gravity to the edge of the side plate 61. The receiving platform 20 is rotatably connected to the top wall of the clearance groove 63. The driving structure 30 is connected to the side plate 61 with the clearance groove 63 and is located on the side of the side plate 61 away from the falling channel 62.

[0044] By setting the clearance groove 63, the drive structure 30 can be connected to the receiving platform 20 through the clearance groove 63 and can drive the receiving platform 20 to rotate. The drive structure 30 and the receiving platform 20 can be integrated on the drop box 60, making the internal layout of the entire drop box 60 more compact. In addition, setting the clearance groove 63 greatly reduces the external space required by the receiving platform 20 during rotation, further realizing miniaturization.

[0045] Optionally, the drive structure 30 is a cylinder, which includes a piston rod 31. The edge of the receiving platform 20 is hinged to the top wall of the clearance groove 63, and a connecting block 32 is connected between the receiving platform 20 and the piston rod 31 of the drive structure 30. One end of the connecting block 32 is connected to the receiving platform 20, and the other end of the connecting block 32 is hinged to the piston rod 31 of the drive structure 30. Therefore, the receiving platform 20 can be rotated by the extension and retraction of the piston rod 31.

[0046] Understandably, among the multiple side plates 61 of the drop box 60, the side plate 61 corresponding to the conveying surface of the conveying structure 50 is shorter, so there is a gap between the side plate 61 corresponding to the conveying surface of the conveying structure 50 and the conveying surface of the conveying structure 50, allowing the material 200 located inside the drop box 60 on the conveying structure 50 to flow outward through the gap between the side plate 61 and the conveying surface of the conveying structure 50; while the side plates 61 in the drop box 60 that do not correspond to the conveying surface of the conveying structure 50 are longer, allowing the side plates 61 in the drop box 60 that do not correspond to the conveying surface of the conveying structure 50 to be connected to the conveying structure 50, thereby connecting the drop box 60 as a whole to the conveying structure 50 and ensuring the stability of the position of the drop box 60 and the conveying structure 50.

[0047] In some embodiments, such as Figure 1 and Figure 3 As shown, the drop test device also includes a guide structure 70 disposed on the conveying structure 50. The conveying structure 50 has a collection area 51, and the detection mechanism 40 can collect images within the collection area 51. The guide structure 70 is used to guide the material 200 to move to the collection area 51 during the material 200 conveying process. During the conveying process, the guide structure 70 gradually straightens the material 200, guiding and precisely positioning it to the preset collection area 51. This ensures that the material 200 is in the exact center of the camera's field of view during each test, improving the reliability and consistency of the test results. Understandably, the collection area 51 is the "preset position".

[0048] Optionally, such as Figure 1 and Figure 3As shown, the guiding structure 70 is a guiding plate 71. The guiding plate 71 abuts against the material 200 during the material 200 conveying process to guide the material 200 to the collection area 51. Two guiding plates 71 are arranged at intervals, forming a moving channel between the two guiding plates 71. Along the conveying direction of the conveying structure 50, the interval between the two guiding plates 71 decreases and connects with the collection area 51, thereby better guiding the material 200 to the collection area 51.

[0049] Optionally, in this embodiment, a protective layer is affixed to the surfaces of the side panel 61 and the guide plate 71. The protective layer is made of a soft material. By affixing the protective layer, the material 200 can be prevented from making hard contact with the side panel 61 or the guide plate 71, thereby avoiding damage to the surface of the material 200. Specifically, the material of the protective layer is simulated leather.

[0050] In some embodiments, such as Figure 2 As shown, the release structure 10 includes a linear motion mechanism 11 and an adsorption mechanism 12 slidably disposed on the linear motion mechanism 11. The linear motion mechanism 11 drives the adsorption mechanism 12 to move in three-dimensional space, and the adsorption mechanism 12 adsorbs or releases the material 200. Through the linear motion mechanism 11, the adsorption mechanism 12 can be driven to perform precise movement in three-dimensional space, enabling precise movement of the material 200 to any preset drop starting point, ensuring the consistency of the initial position of the material 200 during each drop. The adsorption mechanism 12 can be connected to a vacuum generator, gripping the material 200 through negative pressure adsorption. Compared with traditional mechanical grippers, vacuum adsorption avoids pinching, scratching, or indentation caused by clamping force on the surface of the material 200. Optionally, the adsorption mechanism 12 can be a suction cup or the like.

[0051] In some embodiments, such as Figure 5 As shown, the drop test device is provided with a loading station 300 and a pickup station 400 along a preset direction b. The drop test device also includes a loading structure 81, which includes a sliding driver 813, a first loading mechanism 811 for carrying material 200, and a second loading mechanism 812 located below the first loading mechanism 811 for carrying material 200. The first loading mechanism 811 and the second loading mechanism 812 are both slidably arranged along the preset direction b. The release structure 10 is provided at the pickup station 400. The sliding driver 813 is used to drive the first loading mechanism 811 and the second loading mechanism 812 to slide back and forth between the loading station 300 and the pickup station 400. The first loading mechanism 811 or the second loading mechanism 812 receives the material 200 to be tested at the loading station 300 and conveys the material 200 to the pickup station 400. The release structure 10 adsorbs the material 200 at the pickup station 400.

[0052] By placing the second loading mechanism 812 below the first loading mechanism 811, the running paths of the second loading mechanism 812 and the first loading mechanism 811 are vertically offset. Therefore, both the first loading mechanism 811 and the second loading mechanism 812 can simultaneously slide back and forth between the loading station 300 and the picking station 400 without interfering with each other. When the first loading mechanism 811 is carrying material 200 and waiting to be picked up at the picking station 400, the sliding driver 813 can simultaneously drive the second loading mechanism 812 to slide to the loading station 300 to receive the next material 200 to be tested. Conversely, when the material 200 on the second loading mechanism 812 is waiting to be picked up at the picking station 400, the first loading mechanism 811 can return to the loading station 300 to perform the loading operation. This achieves synchronous loading and picking, thereby significantly improving the overall production cycle time and increasing production efficiency.

[0053] Optionally, the sliding driver 813 includes a driving member 8132 and a rotatably mounted synchronous belt 8131. The driving member 8132 drives the synchronous belt 8131 to rotate. The first loading mechanism 811 and the second loading mechanism 812 are respectively connected to the belt surfaces on opposite sides of the synchronous belt 8131, so that the synchronous belt 8131 drives the first loading mechanism 811 and the second loading mechanism 812 to slide alternately. In addition, the feeding structure 81 also includes a slide rail 83, which extends along a preset direction b. Two slide rails 83 are arranged at intervals. The first loading mechanism 811 and the second loading mechanism 812 are slidably connected to the two slide rails 83, thereby guiding the sliding of the first loading mechanism 811 and the second loading mechanism 812. In addition, the feeding station 300 is provided with a feeding cover 82, which has a feeding port 821. Material 200 can be fed into the feeding port 821 through an external structure, such as a robotic arm.

[0054] In some embodiments, such as Figure 1 As shown, the drop test device also includes a material transfer structure 93, a first conveyor line 91 spaced apart from the material transfer structure 93, and a second conveyor line 92 spaced apart from the material transfer structure 93. The material transfer structure 93 is used to pick up the qualified material 200 from the conveyor structure 50 and transfer it to the first conveyor line 91. The material transfer structure 93 is also used to pick up the unqualified material 200 from the conveyor structure 50 and transfer it to the second conveyor line 92.

[0055] Understandably, after the test, the material transfer structure 93 can pick up the tested material 200 from the conveying structure 50. The material transfer structure 93 transfers the qualified material 200 from the conveying structure 50 to the first conveyor line 91, and transfers the unqualified material 200 from the conveying structure 50 to the second conveyor line 92. Thus, this application can automatically transfer qualified and unqualified materials 200 to different positions through the cooperation of the conveying structure 50, the material transfer structure 93, the first conveyor line 91 and the second conveyor line 92, so as to facilitate subsequent material processing and improve production efficiency.

[0056] Specifically, in this application embodiment, the first conveyor line 91, the second conveyor line 92, and the conveying structure 50 can all be belt transmission structures. The belt transmission structure comprises a driving pulley, a driven pulley, and an annular belt tensioned on the two pulleys. Due to the tension, a clamping force is generated at the contact portion between the belt and the pulleys. When the driving pulley rotates, it drives the belt through friction, and the belt drives the driven pulley to rotate. Because belt transmission relies on friction, it can effectively mitigate the impact of the load, resulting in smooth and noiseless operation. Optionally, as... Figure 6 As shown, the material transfer structure 93 includes a multi-axis robotic arm 931 and a clamping mechanism 932 connected to the multi-axis robotic arm 931. The clamping mechanism 932 is used to clamp the material 200, and the multi-axis robotic arm 931 is used to drive the clamping mechanism 932 and the material 200 to move in three-dimensional space.

[0057] In some embodiments, such as Figure 6 and Figure 7 As shown, a flipping structure 94 is provided on the first conveyor line 91. The flipping structure 94 includes a support base 941 spanning above the first conveyor line 91, a rotary driver 942 connected to the support base 941, and a gripping mechanism 943 connected to the rotary driver 942. The material transfer structure 93 releases the material 200 to the gripping mechanism 943. The gripping mechanism 943 is used to grip or release the material 200. The rotary driver 942 is used to drive the gripping mechanism 943 to rotate so that the material 200 gripped by the gripping mechanism 943 faces or turns away from the first conveyor line 91.

[0058] Understandably, material 200 includes a first surface and a second surface. After material 200 has finished falling, it may be with the first surface or the second surface facing up. If it is ultimately necessary to make all materials 200 with the first surface facing up, and when the second surface of material 200 held by a certain material transfer structure 93 is facing up, then it is necessary to flip material 200 180 degrees through flipping structure 94 so that material 200 is flipped to the first surface facing up and falls on the conveying surface of the first conveyor line 91 to continue to be conveyed forward. The placement state of material 200 can be quickly adjusted through flipping structure 94, making the testing device more intelligent.

[0059] Specifically, when the gripping mechanism 943 is ready to receive material, the rotary driver 942 drives the gripping mechanism 943 to rotate, so that the gripping mechanism 943 faces upward. At this time, the material transfer structure 93 above the gripping mechanism 943 releases the material 200 onto the gripping mechanism 943. After the gripping structure grips the material 200, the rotary driver 942 drives the gripping mechanism 943 to rotate 180 degrees, so that the material 200 gripped by the gripping mechanism 943 faces the first conveyor line 91. Then the gripping mechanism 943 releases the material 200, thereby realizing the release of the flipped material 200 to the first conveyor line 91.

[0060] In some embodiments, such as Figure 7 As shown, the gripping mechanism 943 includes a connecting frame 9431 connected to the rotary driver 942, a clamping driver 9432 connected to the connecting frame 9431, and a clamping member 9433 slidably connected to the connecting frame 9431. Two clamping members 9433 are spaced apart. The clamping driver 9432 is used to drive the two clamping members 9433 to move towards each other or away from each other.

[0061] By setting two clamping elements 9433, which move towards each other under the drive of the clamping driver 9432, the material 200 can be clamped from both sides. This symmetrical clamping method can adapt to materials 200 of different sizes and models, ensuring that the center of the clamping force is aligned with the center of mass of the material 200. Furthermore, the clamping method avoids the risks of unstable adsorption or detachment due to uneven surface of the material 200 that may occur with single-point adsorption. At the same time, by controlling the output force of the clamping driver 9432, the clamping force can be precisely controlled, providing sufficient clamping force to resist inertial impacts without causing indentations or damage to the material 200 due to excessive clamping force, achieving a balance between stability and non-destructive operation.

[0062] The present invention also proposes a watch production line, which includes a drop testing device. The specific structure of the drop testing device is as described in the above embodiments. Since this watch production line 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.

[0063] In summary, the drop test device provided in this application, when the receiving platform 20 is in the first position, the release structure 10 drives the material 200 to be tested to move to a preset height and releases the material 200. After release, the material 200 undergoes free fall, and the receiving platform 20 can catch the material 200. After catching the material 200, the receiving platform 20 switches to the second position under the drive of the drive structure 30. Since the receiving platform 20 is set at an angle to the conveying surface of the conveying structure 50, the material 200 on the receiving platform 20 slides towards the conveying structure 50 under the action of gravity. The conveying structure 50 then... The material 200 on the conveying structure 50 is conveyed and tested by the testing mechanism 40. The entire process is automated through the release structure 10, receiving platform 20, drive structure 30 and testing mechanism 40, which reduces manual operation and greatly improves the degree of automation. After the material 200 completes the drop test, it can be automatically guided to the conveying structure 50 immediately. It can flow to the testing position through the conveying structure 50 without stopping, avoiding the impact of the drop position on the testing of the next material 200. This allows the testing device to continuously perform drop tests at a very high rate, which greatly improves production efficiency.

[0064] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
