While the first turntable is performing electrical parameter testing, etc., the second turntable can perform marking and front vision inspection, and the two processes are carried out in parallel, making full use of time, avoiding the situation where other equipment idles and waits when one equipment is working in the traditional way, greatly reducing the overall idle time of the equipment and the switching waiting time between processes, significantly improving the processing efficiency of products per unit time, meeting the requirements of mass production, and thus effectively reducing the production cost.

[0058] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar components or components with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0059] In one embodiment, a quartz crystal resonator testing, marking, detecting, and packaging process is based on a quartz crystal resonator testing, marking, detecting, and packaging device as shown in Figure 1-2 The device includes a loading module 100, a processing module 200, and a packaging module 300. The processing module 200 includes a first turntable 211 and a second turntable 212. The processing module further includes an exchange station 510, and the exchange station 510 is located at the position directly opposite to the first turntable 211 and the second turntable 212. Refer to Figure 4 , and the process includes the following steps:

[0060] S100. The loading module outputs the quartz crystal resonator with the front side facing up to the processing module.

[0061] In a specific embodiment, the step S100 specifically includes: the quartz crystal resonator with the front side facing down is blown off, and the quartz crystal resonator with the front side facing up is continuously conveyed to the processing module. The loading module may include a hopper, a spiral feeding track, and a nozzle 1. The spiral feeding track is arranged on the inner side wall of the hopper. The spiral feeding track includes a blowing section. The nozzle 1 blows air continuously towards the inner bottom of the hopper facing the blowing section. The quartz crystal resonator with the front side facing down is blown off by the nozzle into the inner bottom of the hopper at the blowing section. The front side of the quartz crystal resonator is usually relatively flat and may even be polished to ensure the smoothness of the front side. The back side of the quartz crystal resonator needs to include other functional structures, such as a mounting bracket or additional electrodes, etc., so the roughness is relatively high. Therefore, when affected by the same air flow, the force on the back side of the quartz crystal resonator is greater than the force on its front side. At this time, only by setting the magnitude of the air flow ejected by the nozzle 1 can the quartz crystal resonator with the front side facing up pass through the blowing section of the spiral track smoothly without being blown off, and the quartz crystal resonator with the front side facing down falls into the inner bottom of the hopper under the blowing of the nozzle, thus ensuring to a certain extent that the quartz crystal resonator output from the feeding device has the front side facing up for subsequent testing, marking, detecting, and packaging, etc.

[0062] Furthermore, the bottom surface width of the blowing section is smaller than the bottom surface width of other sections of the spiral feeding track, so that when the quartz crystal resonator passes through the blowing section, the supporting area of its bottom surface is reduced, the stability becomes relatively weaker, and it is more easily affected by the external air flow, creating favorable conditions for distinguishing the front and back sides of the quartz crystal resonator by the nozzle 1.

[0063] In another specific embodiment, step S100 specifically includes: detecting the front and back sides of the transported quartz crystal resonator, blowing off the quartz crystal resonator facing up, and continuously transporting the quartz crystal resonator facing up to the processing module. The loading module may further include a front and back detection optical fiber and a second air nozzle. The front and back detection optical fiber is used to detect the front and back sides of the quartz crystal resonator on the spiral material track. When a quartz crystal resonator facing down is detected, the front and back detection optical fiber issues an air blowing command; the second air nozzle is disposed downstream of the front and back detection optical fiber, and the second air nozzle blows air toward the inner bottom of the hopper facing the spiral material track according to the air blowing command.

[0064] In other specific embodiments, step S100 can also output the quartz crystal resonator facing up to the processing module through other processes, such as through screening by a rotating sieve plate structure, where the quartz crystal resonator facing up and falling into the sieve hole will rotate with the sieve plate to a specific discharge position; or through visual recognition combined with robotic arm sorting, electrostatic adsorption to distinguish the front and back sides, and other processes.

[0065] In another specific embodiment, step S100 further specifically includes: the quartz crystal resonators facing upward are arranged in a straight line and continuously transported to the processing module. The loading module also includes a flat track, one end of which is connected to the output end of the spiral material track and the other end is the output end of the feeding device. The flat track transports the quartz crystal resonators through vibration. The flat track is configured as a straight line to ensure that the quartz crystal resonators can be transported stably and orderly. The portion of the flat track that connects to the spiral material track gradually becomes flat along the output end of the spiral material track until it is horizontal. The flat track vibration mechanism provides piezoelectric frequency vibration to drive the material movement within the flat track.

[0066] S200: The processing module processes the quartz crystal resonator facing upward, and outputs qualified quartz crystal resonators to the packaging module.

[0067] S300: The packaging module packages the qualified quartz crystal resonators.

[0068] Specifically, after receiving qualified quartz crystal resonators from the processing module, the packaging module will package them. For example, carrier tape packaging may be used, and the quartz crystal resonators may be neatly packaged in the carrier tape through a series of packaging mechanisms (such as filling, heat sealing, and tape cutting). Or other common packaging forms such as paper boxes may be used to ensure that the products are properly protected during transportation and storage, while also facilitating subsequent operations such as product counting, handling, and sales.

[0069] Among them, step S200 is performed synchronously on the first turntable and the second turntable, and it includes steps S210 and S220. Specifically, the first turntable sucks and drives the quartz crystal resonator to perform various process steps through a plurality of evenly distributed suction nozzles thereon, and the second turntable carries and drives the quartz crystal resonator to perform various process steps through a plurality of evenly distributed temporary placement platforms thereon. The first turntable is sequentially provided with an output end of the loading module, a positioning mechanism one for positioning the quartz crystal resonator, a testing mechanism one for testing the electrical parameters of the quartz crystal resonator, a testing mechanism two for testing the insulation performance of the quartz crystal resonator, a positioning mechanism three for positioning the quartz crystal resonator, a detection mechanism two for performing bottom vision inspection on the quartz crystal resonator, a rejection mechanism two for discharging the quartz crystal resonator with unqualified insulation performance test and / or bottom vision inspection, a recognition mechanism four for identifying the presence or absence of the quartz crystal resonator, and an input end of the packaging module along its circumferential direction. The second turntable is sequentially provided with a recognition mechanism one for identifying the presence or absence of the quartz crystal resonator, a positioning mechanism two for positioning the quartz crystal resonator, a marking mechanism, a recognition mechanism two for identifying the presence or absence of the quartz crystal resonator, a detection mechanism one, a rejection mechanism one, and a recognition mechanism three for identifying the presence or absence of the quartz crystal resonator along its circumferential direction.

[0070] See Figure 5 , in the step S210, the first turntable rotates and drives the quartz crystal resonator to sequentially perform the following process steps:

[0071] S211. Loading, receiving the quartz crystal resonator with the front side facing up conveyed by the loading module. The first turntable starts to receive the quartz crystal resonator with the front side facing up conveyed by the loading module in this step. The evenly distributed suction nozzles on its circumference precisely suck the product. The suction nozzles cooperate with the external vacuum system to ensure firm adsorption of the quartz crystal resonator by generating negative pressure, so that the product will not fall or shift during the subsequent rotation of the turntable, ensuring the normal progress of the subsequent processes.

[0072] S212. First test, testing the electrical parameters of the quartz crystal resonator. After the loading is completed, as the first turntable rotates, the quartz crystal resonator is brought to the first test station, where there is a professional testing mechanism one for testing the electrical parameters of the quartz crystal resonator, such as a high-precision frequency tester, an equivalent series resistance measuring instrument, etc. By electrically connecting to the quartz crystal resonator, key electrical parameters such as its oscillation frequency and equivalent series resistance are accurately measured to determine whether the product initially meets the requirements in terms of electrical performance. The test results will be transmitted to the control system in real time for subsequent process decisions.

[0073] S213. Exchange, output the quartz crystal resonator that has completed steps S211 - S212 to the second turntable, and receive the quartz crystal resonator that has completed steps S222 - S224. After the previous electrical parameter tests, the first turntable rotates to the exchange station, outputs the quartz crystal resonator that has completed steps S211 - S212 to the second turntable. This process involves the nozzle releasing the product and precisely docking with the temporary placement table on the second turntable. At the same time, the first turntable will also receive the quartz crystal resonator that has completed the corresponding processes (i.e., steps S222 - S224) on the second turntable at this station, realizing the material flow and connection between the two turntables and ensuring the coherence of the entire process.

[0074] S214. Test 2, conduct an insulation performance test on the quartz crystal resonator that has completed the process on the second turntable. After receiving the quartz crystal resonator from the second turntable, the first turntable continues to rotate, bringing the product to the Test 2 station for an insulation performance test. At this station, testing mechanism 2 such as a leakage current tester, insulation resistance tester, etc. will be used to detect the insulation performance of the quartz crystal resonator according to the set test method, checking for problems such as leakage and non - compliance of the insulation resistance with the standard, ensuring that the product will not malfunction due to insulation problems during subsequent use.

[0075] S215. Inspection 2, conduct a bottom visual inspection on the quartz crystal resonator. The quartz crystal resonator is sent to the Inspection 2 station, and through inspection mechanism 2 such as a high - definition camera, a suitable lighting system, and an image - processing algorithm, a bottom visual inspection is carried out on the quartz crystal resonator from the bottom to determine whether there are problems such as cracks, scratches, uneven coating, etc. After image acquisition, the intelligent algorithm analyzes and judges to accurately identify the products with appearance defects.

[0076] S216. Scrap 2, the quartz crystal resonators that fail the insulation performance test and / or the bottom visual inspection are removed from the production line. If the quartz crystal resonator is found to be unqualified in the insulation performance test and / or the bottom visual inspection, then at this station, the unqualified product will be removed from the production line and removed from the production line through the Scrap mechanism 2, preventing unqualified products from mixing into the subsequent packaging process, wasting packaging resources and affecting the quality of the final product.

[0077] S217. Feeding, output the quartz crystal resonator to the packaging module. For the quartz crystal resonators that have passed all the previous tests, marking, and inspections, the first turntable will transport them to the packaging module to prepare for the final packing process, ensuring that only qualified products enter the packaging process.

[0078] Among them, the exchange station is located between the first test mechanism and the second test mechanism, and is also located between the second positioning mechanism and the first detection mechanism; at the exchange station, the suction nozzle releases a quartz crystal resonator onto the temporary placement table and picks up a quartz crystal resonator from the next temporary placement table. The first test mechanism includes a probe test mechanism mounting base, test probes, and a test probe board. The test probes are used to contact the electrodes of the quartz crystal resonator and obtain electrical parameter signals; the test probe board is arranged on the probe test mechanism mounting base, and a plurality of the test probes are fixedly and signal-connected to the test probe board. The test probe board outputs electrical parameter signals through test probe board connection wires. The first test mechanism can also be set to other structures, such as a capacitive coupling test structure, an electromagnetic induction test structure, a microelectromechanical system (MEMS) test structure, a system-on-chip (SoC) test structure, a laser interference test structure, a spectral analysis test structure, etc.

[0079] The second test mechanism can include common insulation testers such as an insulation resistance tester, a leakage current tester, an LC comprehensive tester, or an electrostatic capacitance scanning tester, etc., which are used to perform insulation performance tests on the quartz crystal resonators to ensure that the insulation performance of each quartz crystal resonator meets the standards and provide reliable quality assurance for subsequent use.

[0080] The second detection mechanism includes a camera part and a light source irradiation part. The camera part includes a camera adjustment mounting base and a camera arranged on the camera adjustment mounting base. The camera adjustment mounting base is used to adjust the position and shooting angle of the camera; the light source irradiation part includes a light source mounting base, a reflecting prism, and an annular light source arranged on the light source mounting base. Among them, the reflecting prism reflects the light irradiated by the annular light source to the bottom of the quartz crystal resonator at a certain angle to the camera, and the centers of the camera and the reflecting prism are on the same horizontal line. The second detection mechanism can also be set to other structures, such as a line scan camera detection structure, a binocular stereo vision detection structure, a machine vision-based multispectral detection structure, etc.

[0081] The second waste material mechanism includes a second air nozzle and a collection mechanism. The quartz crystal resonators with unqualified items in the electrical parameter test, insulation performance test, and bottom vision detection are blown into the collection mechanism by the second air nozzle at the second waste material station. Among them, the blowing force of the air flow ejected by the second air nozzle is greater than the suction force of the suction nozzle, so that the second air nozzle can easily blow away the unqualified products picked up by the suction nozzle.

[0082] See Figure 6 , the S220, the second turntable rotates and drives the quartz crystal resonator to sequentially perform the following process steps:

[0083] S221. Exchange: Receive the quartz crystal resonators that have completed steps S211 - S212 and output the quartz crystal resonators that have completed steps S222 - S224. The second turntable receives the quartz crystal resonators that have completed steps S211 - S212 from the first turntable at the exchange station. Similarly, it relies on the temporary storage table to receive the products to ensure the accuracy of the receiving process. And after the subsequent processes are completed, the quartz crystal resonators that have completed steps S222 - S224 are output back to the first turntable through this station, realizing the material cycle and collaborative work between the first turntable and the second turntable.

[0084] S222. Marking: Mark the quartz crystal resonators that have completed steps S211 - S212. Specifically, after receiving the quartz crystal resonators, as the second turntable rotates, the products enter the marking station. The marking mechanism will use technologies such as laser marking. According to information such as the model, batch, and parameters of the products, it will precisely control parameters such as the power, pulse frequency, and spot size of the laser to mark a clear, durable, and standardized identification on the front of the quartz crystal resonator, facilitating subsequent product identification, quality traceability, and market circulation management.

[0085] S223. Inspection 1: Conduct a front - side visual inspection of the quartz crystal resonator. After marking, the quartz crystal resonator is sent to the inspection 1 station, where the inspection mechanism 1 conducts a visual inspection of the product from the front side. On the one hand, it checks the marking effect, such as the clarity, integrity, and accuracy of the marking position of the font; on the other hand, it also screens the appearance quality of the front side of the product to check for defects such as scratches and impurities, and timely discovers problems in marking and appearance.

[0086] S224. Scrap 1: The quartz crystal resonators that are unqualified in the electrical parameter test and / or front - side visual inspection are removed. If the quartz crystal resonator is found to be unqualified in the electrical parameter test (step S212 of the first turntable) and / or the front - side visual inspection (step S223 of the second turntable), it will be removed at this station, and the unqualified products will be removed by the scrap mechanism 1 to ensure that all products finally transported to the packaging module are strictly screened qualified products.

[0087] Among them, an air suction port can be arranged in the middle of the temporary placement table. The air suction port forms a negative pressure through air suction, so that the quartz crystal resonator can be more firmly carried on the temporary placement table. During the movement of the quartz crystal resonator along with the temporary placement table, it is not easy to have relative displacement with the temporary placement table. The marking mechanism can include a marking adjustment mounting seat with adjustable height and angle, a laser installed at the upper end of the marking adjustment mounting seat, and a laser head installed at one end of the laser. The laser is used to generate a laser beam and emit it to the quartz crystal resonator at the marking station through the laser head. The first detection mechanism can include an installation adjustment bracket, a red light annular light source and a black and white camera installed on the installation adjustment bracket. The black and white camera is located directly above the red light annular light source; the red light annular light source emits light downward directly facing the quartz crystal resonator at the first detection station, and the black and white camera is used to capture the image of the quartz crystal resonator. The structure of the first waste material removing mechanism can be the same as that of the second waste material removing mechanism.

[0088] In the quartz crystal resonator testing, marking, detection, and packaging process of this embodiment, based on specific quartz crystal resonator testing, marking, detection, and packaging equipment, the first turntable and the second turntable in its processing module perform different processes synchronously, and realize the efficient flow and collaborative operation of materials through exchanging workstations. While the first turntable is performing electrical parameter testing, etc., the second turntable can perform marking and front vision detection. The two processes are carried out in parallel, making full use of time, avoiding the situation where other equipment idles and waits when one piece of equipment is working in the traditional way, greatly reducing the overall idle time of the equipment and the switching waiting time between processes, significantly improving the processing efficiency of products per unit time, meeting the requirements of mass production, and thus effectively reducing the production cost.

[0089] The whole process is highly automated. From the feeding of the quartz crystal resonator, multiple tests, marking, and detection in the processing module to the final packaging, each link depends on the high-precision instruments, automated mechanisms, and precise control on the equipment to complete. Compared with the prior art that requires manual cooperation to complete material handling, operation connection, etc. between different pieces of equipment, this process greatly reduces the participation of manual operations, reduces the dependence on manpower, saves a large amount of labor costs, and at the same time avoids the mistakes and uncertainties that may be brought by manual operations, further ensuring the stability of the production process and the consistency of product quality. The integrated equipment and process make the data in the production process easier to collect and manage, providing strong support for production management and quality improvement.

[0090] In one embodiment, the step S216 specifically includes: separately discharging the quartz crystal resonators with unqualified insulation performance tests and the quartz crystal resonators with unqualified bottom vision inspections into different spaces; the step S224 specifically includes: separately discharging the quartz crystal resonators with unqualified electrical parameter tests and the quartz crystal resonators with unqualified front vision inspections into different spaces. Specifically, the collection mechanism includes a collection mechanism mounting base, as well as defective product cups and material passing pipes provided on the collection mechanism mounting base. The unqualified quartz crystal resonators fall into the defective product cups through the material passing pipes. The collection mechanism further includes a cylinder. There are two defective product cups. The two defective product cups of the first waste discharging mechanism respectively load the quartz crystal resonators with unqualified electrical parameter tests and the quartz crystal resonators with unqualified front vision inspections. The two defective product cups of the second waste discharging mechanism respectively load the quartz crystal resonators with unqualified insulation performance tests and the quartz crystal resonators with unqualified bottom vision inspections, so as to subsequently detect, analyze or recycle different unqualified products respectively. The material passing pipe includes two pipes and a pipe head. The quartz crystal resonators enter different defective product cups from the pipe head and the pipes. The pipe connected to the pipe head is switched according to the cylinder detection result, so as to realize the classified collection of different unqualified products.

[0091] In one embodiment, before step S212, there is also: positioning one, performing a first positioning on the quartz crystal resonator. Before the electrical parameter test (step S212) on the first turntable, a first positioning is performed on the quartz crystal resonator. This positioning step is mainly to ensure that the quartz crystal resonator is in an accurate position during the electrical parameter test, so that the test instrument can accurately contact the quartz crystal resonator and obtain accurate test data. The first positioning mechanism is arranged on the periphery of the first turntable, at a position after receiving the quartz crystal resonator conveyed by the receiving and feeding module (step S211) and before the electrical parameter test (step S212).

[0092] Before step S222, there is also: positioning two, performing a second positioning on the quartz crystal resonator. A second positioning is performed before the marking (step S222) on the second turntable. The marking operation requires high-precision position control, and positioning is required to ensure that the mark can be accurately made on the predetermined position of the quartz crystal resonator, such as the center area of the front of the product or a specific identification area. The second positioning mechanism is located on the periphery of the second turntable, at a position after receiving the quartz crystal resonator from the first turntable (S221) and before the marking (S222). Among them, the quartz crystal resonator can perform the second positioning and the marking at the same position on the periphery of the second turntable respectively, so as to prevent the quartz crystal resonator from shifting again as the turntable rotates after positioning, affecting the accuracy of the marking.

[0093] Before step S215, the following steps are also included: Positioning three, which is the third positioning of the quartz crystal resonator. The third positioning is carried out before the bottom vision inspection on the first turntable (step S215). The bottom vision inspection mainly checks the appearance defects at the bottom of the quartz crystal resonator, such as cracks, scratches, etc. In order to obtain a clear and complete bottom image, it is necessary to accurately position the quartz crystal resonator to ensure that its bottom is completely within the field of view of the vision inspection system and maintains a stable posture. The positioning mechanism three is arranged on the first turntable, at the position after receiving the quartz crystal resonator from the second turntable (S213), completing the insulation performance test (S214), and before the bottom vision inspection (S215).

[0094] In one embodiment, both positioning one and positioning three specifically include: Two pairs of claw pieces with perpendicular clamping directions position the quartz crystal resonator in four directions on a plane. Specifically, both the positioning mechanism one and / or the positioning mechanism three include a positioning motor one and a positioning cam mechanism connected in transmission, and four positioning claw pieces arranged orthogonally. The positioning motor one drives the positioning cam mechanism to rotate, and the positioning cam mechanism drives the four positioning claw pieces to open / close to correct the position of the quartz crystal resonator. In other embodiments, the positioning mechanism one and the positioning mechanism three can also adopt a combination of mechanical positioning and optical positioning.

[0095] Positioning two specifically includes: A positioning block protruding vertically upward is formed on the temporary placement table, and the positioning piece pushes the quartz crystal resonator to abut against the positioning block to complete the positioning of the quartz crystal resonator. The positioning mechanism two includes a positioning mounting base, a positioning motor two and a positioning slide table mounted on the positioning mounting base, and a positioning piece fixedly connected to one end of the positioning slide table. The positioning motor two drives the positioning slide table to reciprocate and drives the positioning piece to reciprocate. When receiving the positioning instruction sent by the control system, the positioning motor two accurately starts according to the preset program and parameters, rotates at the required speed and direction, and drives the positioning slide table to perform a linear forward and backward movement. The positioning piece gradually approaches the quartz crystal resonator as the positioning slide table moves. When it contacts the product, it accurately corrects the position of the product on the temporary placement table to ensure that the key position parameters such as its center and angle meet the requirements of subsequent marking or inspection processes. The positioning mechanism two can also adopt a combination of mechanical positioning and optical positioning, or a combination of a vision positioning system and a micro-motion platform.

[0096] In one embodiment, after step S221, it further includes: Identification 1, identifying whether there is a quartz crystal resonator. If there is, the subsequent steps are carried out; if not, the subsequent steps are suspended. After the second turntable receives the quartz crystal resonator that has completed a specific process from the first turntable (step S221), the Identification 1 process is immediately started. This identification process is usually completed by an identification mechanism 1 (such as a photoelectric sensor, proximity sensor, etc.) installed near the second turntable. The identification mechanism 1 will detect in real time whether there is a quartz crystal resonator on the temporary placement table. If it detects that there is a quartz crystal resonator, the control system will determine that the condition is met, and then trigger subsequent steps, such as positioning, marking, etc.; if the identification mechanism 1 does not detect a quartz crystal resonator, that is, the identification result is none, the control system will suspend the subsequent steps to avoid performing unnecessary operations such as positioning and marking on the empty temporary placement table. If the identification result is always none, it may also trigger an alarm to prompt the staff to check relevant links, such as whether the material transportation between the first turntable and the second turntable is normal.

[0097] After step S222, it further includes: Identification 2, identifying whether there is a quartz crystal resonator. If there is, the subsequent steps are carried out; if not, the subsequent steps are suspended. After completing the marking process (S222), the Identification 2 process is started. Similarly, with the help of an identification mechanism 2 (such as a photoelectric sensor, proximity sensor, etc.), the presence or absence of a quartz crystal resonator on the temporary placement table after marking is identified. If it is identified that there is a quartz crystal resonator, it means that no abnormal situation such as product loss occurred during the marking process, and the control system allows subsequent steps such as front vision detection (S223) to continue; if the identification result is none, the control system will suspend the subsequent steps to prevent performing ineffective detection operations without a product, and at the same time check the marking process to determine the reason for the absence of the quartz crystal resonator, such as whether the product fell during the marking process.

[0098] After step S224, it further includes: Identification 3, identifying whether there is a quartz crystal resonator. If there is, the subsequent steps are carried out; if not, the subsequent steps are suspended. After completing the front vision detection (step S223) and performing the first rejection (step S224) operation, the Identification 3 process starts. The identification mechanism 3 detects again whether there is still a quartz crystal resonator on the temporary placement table. If there is, it indicates that there is still a qualified quartz crystal resonator after the product has undergone detection and rejection operations, and the qualified quartz crystal resonator will return to the first turntable to continue performing relevant steps; if the identification is none, the subsequent steps are suspended.

[0099] After step S216, the following steps are further included: Identification Four, to identify the presence or absence of a quartz crystal resonator; for the identification of the presence or absence of a quartz crystal resonator, if there is one, subsequent steps are carried out; if not, subsequent steps are suspended. After the first turntable completes the insulation performance test and / or bottom vision inspection and performs the second rejection operation, the Identification Four process comes into play. The identification mechanism four detects whether there is still a quartz crystal resonator on the temporary placement table. If it is detected that there is one, it indicates that there are still qualified quartz crystal resonators after inspection, and the control system will continue with subsequent feeding (S217) and other steps; if it is identified that there is none, subsequent operations are suspended.

[0100] By setting Identification One, Identification Two, Identification Three, and Identification Four at key process nodes, the presence or absence of a quartz crystal resonator can be identified in a timely manner, avoiding ineffective operations on workstations without products, reducing equipment wear and energy consumption, extending the service life of the equipment, and reducing equipment maintenance costs. In addition, the identification operation provides real-time status feedback of the product in the production process, enabling users to timely discover potential problems during the transfer of the product between various processes, optimize the production process, improve the refinement of production management, and ensure the stability of product quality.

[0101] In one embodiment, Identification One, Identification Two, Identification Three, and Identification Four can all identify the presence or absence of a quartz crystal resonator through a fiber optic sensor. Specifically, the fiber optic detection mechanism can include a light source, an optical fiber, a photodetector, etc. The light emitted by the light source is transmitted through the optical fiber to the detection point corresponding to the material identification station. When there is a quartz crystal resonator, the optical signal will change (such as changes in reflection, refraction, scattering, etc.), and then the changed optical signal is transmitted back to the photodetector through the optical fiber. The photodetector converts the change in the optical signal into an electrical signal to determine whether there is a quartz crystal resonator. For example, in a reflective fiber optic sensor, if a quartz crystal resonator is at the detection position, it will change characteristics such as the intensity of the reflected light, thereby achieving detection. Multiple fiber optic detection mechanisms can detect the presence or absence of materials and control the operations of subsequent workstations, avoiding unnecessary operations and improving production efficiency.

[0102] In one embodiment, the first turntable and the second turntable rotate in opposite directions. At the exchange station, the positions of the first turntable and the second turntable are relatively set. Due to their opposite rotation directions, at the exchange station, the moving directions of the edges of the two turntables are the same. For example, when the first turntable rotates clockwise to the exchange station, the moving direction of its edge part is from left to right; while when the second turntable rotates counterclockwise to the exchange station, its edge part also moves from left to right. This enables the suction nozzle on the first turntable to accurately and smoothly release the quartz crystal resonator onto the temporary placement table of the second turntable at the exchange station. At the same time, it can also smoothly pick up the quartz crystal resonator that has completed the corresponding process from the next temporary placement table of the second turntable, realizing efficient and smooth material exchange between the two turntables. The same moving direction makes the impact force and inertia influence on the material smaller during the exchange process. During the transfer of the quartz crystal resonator, the risk of shaking, offset, or even dropping due to the difference in the moving directions of the two turntables is reduced. This ensures the stability of the material exchange, improves the safety of the product during the transfer process, reduces product damage or loss caused by improper material exchange, thereby ensuring the stability of the product quality and reducing the scrap rate.

[0103] In one embodiment, in step S213, the first turntable pauses rotation; in step S221, the second turntable rotates by one indexing. Both step S213 and step S221 are performed at the exchange station.

[0104] Rotating by one indexing means that the second turntable rotates at a pre-set angular interval so that the next temporary placement table can successively reach the exchange station opposite to the suction nozzle of the first turntable. For example, if there are n temporary placement tables evenly distributed on the second turntable, then one indexing is 360° / n. Through this rotation, the temporary placement table that receives the quartz crystal resonator released by the first turntable is transported to the next station of the exchange station. At the same time, the quartz crystal resonator that has completed the process on the second turntable is rotated to the exchange station by the next temporary placement table, so that the suction nozzle waiting for suspension on the first turntable can perform the suction operation. This process ensures that the second turntable can orderly participate in the material exchange link and closely cooperate with the actions of the first turntable.

[0105] Specifically, when starting to use, there is no material on the second turntable. Therefore, at the exchange station, after the suction nozzle releases the quartz crystal resonator, it cannot pick up the quartz crystal resonator from the next temporary placement table. When the suction nozzles on the first turntable continuously release materials to the temporary placement tables on the second turntable until the temporary placement tables are full, at the exchange station, after the suction nozzle releases the quartz crystal resonator, it can pick up the quartz crystal resonator from the next temporary placement table. From this point on, each time a suction nozzle on the first turntable releases a quartz crystal resonator to the second turntable, without waiting for this quartz crystal resonator to be marked and visually inspected on the front side, it can directly pick up a quartz crystal resonator that has been marked and visually inspected on the front side from the next temporary placement table on the second turntable, and then drive it to perform subsequent processes. After that, the processes on the first turntable and the second turntable are carried out synchronously and cooperate with each other. The overall rhythm of the production line is significantly accelerated, the number of products that can be processed per unit time increases significantly, the entire process enters a continuous cycle state, the processes on the first turntable and the second turntable are closely coordinated, and the above operations are continuously repeated according to the established process to ensure the stable and efficient output of qualified products by the production line.
