Technical Field

The application relates to the technical field of camera modules, in particular to a material loading platform suitable for automatic material changing and corresponding automatic module testing equipment.

Background

At present, the camera module has been widely applied to the field of consumer electronics terminals (such as smart phones, tablet computers, notebook computers, etc.), becomes an indispensable part in the life of people, and has a wide market prospect. The camera module is a small and precise product, and precise processing is required in the production process. In the early stage of the industry, the camera module industry spent a growing period mainly by purchasing a small amount of foreign production equipment and combining a large amount of manpower. And, along with intelligent terminal's popularization, the module industry of making a video recording has come a high-speed development period. In this period, small module factories with small volume and immature technology are gradually eliminated, and module factories with mature technology and large volume are left. The module factories digest a large amount of module orders in domestic markets, the production capacity of the orders can reach the level of millions or even millions, the defect that the orders are excessively dependent on manpower production is more and more obvious when the orders reach the level of the order, and semi-automatic or automatic production of mechanical equipment is a necessary trend.

The semi-automatic or automatic production is realized by firstly needing the support of corresponding production equipment, and the equipment can be obtained by two modes of self-research and external purchase. The externally purchased equipment is expensive on one hand, cannot completely meet the production requirements of purchasers due to production reasons (such as secrecy in some production processes) and the like on the other hand, and self-developed equipment can be designed according to the production requirements so as to improve the production efficiency.

The application mainly relates to a camera module detection device. The module of making a video recording detects and is a ring of indispensable in the module production of making a video recording. The camera module inspection apparatus (hereinafter, simply referred to as module inspection apparatus) also faces a major issue of improving the production efficiency. Early module inspection equipment typically had a dedicated inspection equipment for each test session (i.e., each test). And under the development thinking that integrates, have more and more module check out test set integrated a plurality of test links, some module check out test set can integrate whole test links even, namely accomplish whole tests with monomer equipment promptly. On the other hand, for improving production efficiency, some module test equipment have adopted array detection scheme, and a mark board corresponds to the module array of making a video recording that a plurality of modules of making a video recording are constituteed promptly, and this test link can once test a plurality of modules of making a video recording like this to show promotion production efficiency. Moreover, some module test equipment still further will make a video recording the unloading link integration of module in module test equipment to further improve the integrated level of equipment.

Although the prior art has adopted many techniques to improve the module inspection apparatus, the existing module inspection apparatus has many disadvantages, which need to be further improved.

For example, in an integrated module detection device, each functional module is densely arranged in a compact space. Theoretically, this helps to increase the output per unit area. However, this design also results in inconvenient maintenance of the device. When equipment failure, the maintainer will spend more time just can make module check out test set resume production. Therefore, if considering the production interruption time due to the failure, the yield per unit area of the entire excessively integrated module inspection apparatus may not be optimal.

For another example, the camera module is a precise optical device, and during testing, the testing equipment is often required to provide better protection for the camera module, so as to prevent the imaging quality of the camera module from being reduced or even scrapped due to collision, contamination or other reasons. Therefore, the module carrying platform of the testing equipment usually needs to cover the camera module. However, in an automatic production scenario, the cover and the mechanism for moving the cover may need to occupy more space, which adversely affects the miniaturization of the device.

For another example, the camera module carrying platform in the test equipment and the loading and unloading mechanism are compactly configured, which may help to reduce the stroke of module loading and unloading, thereby helping to improve the production efficiency. However, a lid for protecting the module of making a video recording needs frequent opening and shutting, if go up unloading mechanism and the mounting platform of the module of making a video recording too close, probably leads to the material loading in-process to bump, causes equipment shutdown. Meanwhile, the collision brings great inconvenience to maintenance work. How to balance the factors is a big problem in the field, and designing equipment which can reduce the failure rate and has the advantages of miniaturization, high production efficiency and the like.

Further, for other materials similar to the camera module (for example, a structured light projection module, a fingerprint module, etc. in a mobile phone), the above problems may also be encountered when the automation equipment in the detection link or the production link faces a series of problems such as equipment miniaturization and production efficiency improvement.

In summary, there is a need for a solution for a module inspection apparatus (or other automated inspection or production apparatus for materials similar to a camera module) that can overcome the above-mentioned drawbacks.

Each reticle module 200 may correspond to a test station. Each test station can complete at least one module test item. The refueling mechanism 300 corresponds to a refueling station. In this embodiment, each test module 110 may arrive at each station in sequence during rotation to complete each test in combination with each target module 200 disposed about the rotary testing mechanism. The target module 200 may have a separate base frame and housing (mainly suitable for a target module for long-distance and medium-distance tests with a larger volume), or may be directly mounted on the base frame 150 (refer to fig. 2) of the rotary testing mechanism 100 and share the same housing with the rotary testing mechanism 100 (mainly suitable for a target module for short-distance tests with a smaller volume). Further, fig. 2 shows a perspective structure diagram of the rotary testing mechanism in an embodiment of the present application. Referring to fig. 2, in the present embodiment, the rotary testing mechanism 100 includes a turntable 120, a plurality of racks 130, and a plurality of detection modules 110. A plurality of brackets 130 are disposed at the peripheral region of the turntable 120, each bracket 130 is configured to mount one of the detection modules 110, and the front surface of each detection module 110 is vertical and disposed outward in the detection state (refer to the detection module 110b located at the bottom right in fig. 2), that is, the front surface of the detection module 110 faces the target module in the detection state (the target module is not shown in fig. 2). In a non-detection state, such as a refueling state, the front face of the detection module 110 may face upward (see the detection module 110a located at the upper left in fig. 2). Further, fig. 3 is a schematic perspective view illustrating a positional relationship between the detection module and the light curtain device in an embodiment of the present application, and fig. 4 is a schematic top view illustrating a positional relationship between the detection module and the light curtain device in an embodiment of the present application. Referring to fig. 3 and 4 (which only schematically show main components), and referring to fig. 2, in this embodiment, the detection module 110 includes a material stage 111. Further, fig. 5 shows a schematic diagram of a safety protection principle based on a light curtain device in an embodiment of the present application. The open cover state of the tool holder 113 is shown in fig. 5. Referring to fig. 5 in combination, the material carrying platform 111 includes a mounting surface 112 and at least one tooling fixture 113, where the tooling fixture 113 includes a material carrying plate 114 fixed on the mounting surface 112 and a cover 115 pivotally connected to the material carrying plate 114. The target module 200 is suitable for providing a test light source and a target object for a camera module which is loaded in the tool clamp 113 as a material. The material changing mechanism 300 comprises a material taking head 310 which is suitable for moving materials, the material changing mechanism 300 and the plurality of target modules 200 form at least one material changing station and a plurality of testing stations around the turntable 120, and the turntable can drive the detection module 110 to rotate relative to the target modules 200 and the material changing mechanism 300. Wherein, a light curtain device 400 is arranged at the material changing station, which is suitable for generating a light curtain 410 parallel to the mounting surface, and the position of the light curtain 410 is higher than the frock clamp 113 in the state that the cover body 115 is completely opened. And during the process of the material intake head 310 moving laterally (here, the lateral translation refers to the process of moving the material into the area above the material carrier and the process of moving the material out of the area above the material carrier), the material intake head 310 and the material intake by it are always higher than the light curtain. After the cover opening action of each tool clamp of the material carrying table is finished, before the material intake head executes the lifting motion, whether safety measures are started or not can be determined according to whether the duration time of the continuous shielding of the light curtain exceeds a threshold value or not. The safety measure may comprise that the light curtain device gives an alarm and/or stops the operation of the material change mechanism. In actual work, the light curtain device may be always in an on state in the whole detection process, the control program determines whether the current time is in a time interval after the cover opening operation of each tool fixture is completed and before the material pickup head performs the lifting motion, if the determination is yes, a signal of the light curtain device is read, if the light curtain is continuously shielded, it may be considered that a part of components of the material carrier may be abnormal (for example, the cover 115 of the tool fixture 113 may be in an abnormal open state), and at this time, the light curtain device may issue an alarm and/or stop the work of the material changing mechanism, so as to avoid collision between the material picked up by the material changing mechanism or the material changing mechanism and the material carrier. The material carrying platform has the advantages of being small in size, high in reliability, high in material changing efficiency and the like, and is particularly suitable for highly integrated automatic test equipment. Particularly, in this embodiment, through setting up safe light curtain, can be guaranteeing not under the prerequisite of colliding, the guide rail height that will reload the mechanism drops to the position that is closer to the material microscope carrier to reduce the required stroke of unloading on the material, ensure higher production efficiency.

Further, in an embodiment of the present application, the material intake head 310 can perform a lateral translation and a lifting motion, where the lateral translation is a motion with a moving direction parallel to the mounting surface, and the lifting motion is a motion with a moving direction perpendicular to the mounting surface. In an xyz three-dimensional rectangular coordinate system, the lateral translation may be movement in the x-axis and y-axis directions, and the lifting motion may be movement in the z-axis direction. In some embodiments, the lateral translation may further include rotation in the xy plane (i.e., rotation about the z axis) to better achieve alignment of the camera module with the material carrier plate. The material intake head 310 may be a suction nozzle having a suction capability to suck the material, or may be a clamp capable of clamping the material.

During discharging, the material intake head 310 can take material from the material carrying platform of the detection module 110, move along the guide rail 330 to above the material tray area 340, and then discharge the material. In practical operation, the material intake head 310 may perform the unloading process first and then perform the loading process, so as to smoothly complete the material exchange of the single material carrier 111. The tray zone 340 may arrange one or more trays. When a plurality of material trays are arranged, the material trays for bearing untested modules and the material trays for bearing tested modules can be respectively arranged.

The reference surface may be, for example, the ground, or a horizontal work surface with an adaptive balancing mechanism.

Further, fig. 5 shows a schematic diagram of a safety protection principle based on a light curtain device in an embodiment of the present application. Referring to fig. 5, the cover 115 and the material carrier 114 after the tooling fixture 113 is completely opened (i.e. after the tooling fixture is completely opened) have an included angle, which may be referred to as an opening angle (the material carrier 114 bears against the mounting surface 112, so the opening angle may also be understood as an included angle between the cover 115 and the mounting surface 112, when the detection module is in a horizontal posture, the mounting surface is also in a horizontal posture, and at this time, the opening angle may also be understood as an included angle between the cover 115 and a horizontal plane). This design uncap angle value may be 160 °. In this embodiment, in the process of the transverse translation of the material pickup head (not shown in fig. 5), the camera module picked up by the material pickup head is 5mm away from the light curtain (note that, the application is not limited thereto). This height can be achieved by a corresponding arrangement of the guide rails of the change mechanism and the material pick-up head. It is noted that in practice the light sheet has a certain thickness (e.g. 1mm), where 5mm from the light sheet means 5mm from the upper surface of the light sheet, i.e. the upper limit position. In this embodiment, in a state where the cover is completely opened, a highest point of the fixture is 10mm away from the light curtain (note that, the application is not limited thereto). By 10mm from the light sheet is here meant 10mm from the lower surface (i.e. the lower limit position) of the light sheet. The highest point may be, for example, the highest point of the cover body when the tooling fixture is opened to the maximum angle (i.e., in a completely uncapped state), and the highest point may also be located in other structures of the tooling fixture. As described above, after the cover opening operation of each tool clamp of the material carrying table is completed and before the material pickup head performs the lifting motion, whether to start a safety measure is determined according to whether the duration of the continuous shielding of the light curtain exceeds a threshold, where the safety measure may include that the light curtain device sends an alarm and/or stops the work of the material changing mechanism. In actual work, the light curtain device can be always in a connected state in the whole detection process, a control program judges whether the current time interval is after the cover opening action of each tool clamp is finished and before the material intake head executes the lifting motion, if so, a signal of the light curtain device is read, if the light curtain is continuously shielded, part of components of the material carrying platform can be considered to be abnormal (for example, a cover body of the tool clamp is incompletely opened), and at the moment, the light curtain device can send an alarm and/or stop the work of the material changing mechanism so as to avoid collision between the material intake by the material changing mechanism or the material changing mechanism and the material carrying platform. Fig. 5 shows a malfunction caused by incomplete opening of the door. Referring to fig. 5, after the cover opening operation of the tooling fixture is completed, the cover opening angle of the tooling fixture on the right side is only 144 ° and does not reach the design value of 160 °. At this time, the cover blocks the light curtain 410, resulting in the light curtain emitting a signal. When the signal continuously exists, the tool clamp can be judged to be abnormal (for example, the cover body of the tool clamp is not completely opened). In this embodiment, the cover opening and closing actions of the tooling clamp 113 need to be driven by a driving mechanism, and due to various factors such as tolerance and the like, the risk of incomplete cover opening always exists (for example, incomplete cover opening caused by insufficient power of the driving mechanism may occur). If the prevention is not taken, the material changing mechanism or the materials collide with the cover body. Such collisions may cause damage to the equipment or the accuracy of the equipment is severely affected. And after the light curtain device of this embodiment is installed, above-mentioned collision problem can be avoided effectively. It should be noted that due to various factors such as external disturbance, the material loading platform and the material changing mechanism may be misaligned (which is often difficult to observe by naked eyes), and the material changing mechanism or the material collides with the cover body due to the misalignment. Such collision can be effectively avoided by installing the light curtain device of the present embodiment. Note that the preset door opening angle (fully opened door opening angle) is not limited to 160 ° in the present application, and in other embodiments, the door opening angle may be set at 145 ° to 162 °.

Further, the material carrying platform also comprises a cover body driving mechanism which is suitable for driving the cover body to rotate around the rotating pivot. Figure 6 is a schematic perspective view of a single tooling fixture and its drive mechanism at a first angle in a closed position according to one embodiment of the present application. Figure 7 is a perspective view of a single tooling fixture and its drive mechanism at a second angle in a closed position according to one embodiment of the present application. Figure 8 is a schematic perspective view of a single tooling fixture and its drive mechanism at a first angle in an open lid configuration in one embodiment of the present application. Figure 9 is a perspective view of a single tooling fixture and its drive mechanism at a second angle in an open lid configuration in one embodiment of the present application. Referring to fig. 6-9, in this embodiment, the cover driving mechanism may include a cylinder 118 and a crank link 119, the crank link 119 includes a cylinder rod 119a and a driven rod 119b, and the cylinder rod 119a is connected to the piston of the cylinder 118 and driven by the piston to reciprocate. Specifically, the piston may have a piston rod 119c, and the piston rod 119c may be fixed to the bottom of the cylinder rod 119 a. Thus, cylinder rod 119a can reciprocate (e.g., linearly reciprocate) relative to the body of cylinder 118 under the driving of the piston, i.e., cylinder rod 119a can be raised and lowered relative to the body of cylinder 118. One end of the driven rod 119b is movably connected with the cylinder rod 119a, and the other end of the driven rod is connected with the cover body. In this embodiment, the cover body has a root portion near the rotation pivot 117 and an end portion far from the rotation pivot 117, the root portion has a boss structure 115a, and the driven lever 119b is connected to the cover body 115 through the boss structure 115 a. For a single tooling fixture, the pivot shaft 117 may be split into two sections (i.e., pivot shaft 117 may include a first section 117a and a second section 117b, see fig. 7), and the two sections (first section 117a and second section 117b) may have a gap 117c therebetween to form an escape zone that allows the driven rod 119b to pass through (see fig. 8). The cylinder 118 may be located below the material carrier plate 114, the material carrier plate 114 has an avoiding hole 114a (or referred to as an avoiding groove) adapted to the protrusion structure 115a, and the avoiding hole 114a allows the driven rod 119b to pass through. The design can avoid the mutual interference between the cover body driving mechanism and the material replacing mechanism, the space utilization rate is high, and the reduction of the size of the detection module is facilitated.

Further, in an embodiment of the present application, the material loading platform further comprises a position identification sensor for identifying a position of the cylinder rod (i.e. for identifying a relative position of the cylinder rod with respect to the cylinder block), and the material change mechanism starts or stops the lateral translation of the material intake head according to the identified position information. Therefore, the reloading mechanism avoids the uncovering process of the tool clamp according to the identified position information of the cylinder rod. Avoiding collision in the cover opening process. By means of the design, the track for transverse translation of the intake head of the reloading mechanism can be arranged at a lower position, so that the working efficiency is improved. The position recognition sensor is a magnetic sensor or a photoelectric sensor.

Further, still referring to fig. 6 to 9, in an embodiment of the present application, in the material carrying platform, the cover 115 has a through hole 115b adapted to an outer periphery of the lens of the camera module, and the cover covers a portion outside the lens of the camera module after covering.

Further, still referring to fig. 8, in an embodiment of the application, in the material loading platform, each of the tooling fixtures 113 has two camera

module carrying positions

113a and 113 b. Each of the carrier plates 114 is adapted to carry two of the camera modules, and each of the cover plates 115 also has two camera

module adapting structures

115c and 115d, so as to fix the two camera modules after the cover is closed. And each air cylinder is suitable for driving the opening and closing of one tool clamp. Therefore, for the scheme that every frock clamp carried a module of making a video recording, the number of cylinder can be reduced in this kind of design of this embodiment, is favorable to reducing the volume that actuating mechanism took, still can keep higher lid rate of opening and shutting and lower fault rate simultaneously.

Further, in an embodiment of the application, a contact array may be disposed in the material carrier of the tooling fixture, the contact array is adapted to a connector of the camera module carried in the tooling fixture, and after the cover is closed, the cover body presses the camera module under the action of the driving mechanism, so that the connector is in close contact with the contact array. The design is beneficial to realizing efficient and reliable electric connection, so that the time occupied by feeding a single module is reduced, and the production efficiency is improved.

Further, still referring to fig. 2, in an embodiment of the present application, a central receiving case 140 may be disposed at the center of the turntable 120, and a top of the central receiving case 140 may have a through hole to allow a cable to pass therethrough. Cables drawn from the back of each detection module 110 (or other portions thereof) may pass through the through-hole and be received in the central receiving case 140.

Further, still referring to fig. 2, in one embodiment of the present application, the detection module 110 may be 90 ° flipped with respect to the bracket 130 such that the detection module may be switched between a horizontal posture and a vertical posture. The target modules are arranged around the turntable, each target module forms a testing station of the material carrying platform, and each material carrying platform can carry a plurality of camera modules to test. The automatic detection equipment is characterized by further comprising a material changing mechanism (namely a material loading and unloading mechanism), wherein the material loading and unloading mechanism is suitable for taking the camera module placed in the horizontal posture (a material tray for loading the camera module can also be placed horizontally), moving the camera module to the detection module in the horizontal posture and placing the camera module into a tool clamp of the detection module in the horizontal posture. The design of this embodiment can be decomposed the action of going up unloading, and the action of will overturning is handed over by the detection module end and is realized for the mechanism that is used for going up unloading need not have the upset function, and then makes its complexity reduce. In the transmission process, the charging tray and the camera module are generally horizontally placed. After the action is decomposed, the camera module can keep a horizontal state, the loading and unloading time does not need to be additionally occupied due to the overturning action, and the overturning action of the detection module can be carried out simultaneously with the movement of the module, so that the production efficiency is favorably improved. Particularly, when the module of making a video recording that has detected got back to and goes up unloading position (station of reloading promptly), the material microscope carrier can carry out 90 upset for the module of making a video recording goes up and down to go on the horizontal plane, and after the material loading was accomplished, the objective carrier can carry out 90 upset, and then the carousel can rotate, drives the material microscope carrier and removes first detection module, begins to make a video recording the detection of module. In other words, during detection, the material carrying platform is in a vertical state and faces the target board module. In this embodiment, the target module is adapted to provide a light source and a target (e.g., a target) for testing, where the target is a target photographed by the module to be tested. On the other hand, the complexity of the feeding and discharging mechanism is reduced, and particularly the moving freedom degree required by the feeding and discharging mechanism is reduced, so that the space occupied by the moving range is reduced (for example, a multi-joint mechanical arm capable of realizing overturning usually needs to occupy a larger moving space, and a mechanism based on a guide rail with a simpler structure can be used for realizing feeding and discharging after the overturning automation degree is reduced). Therefore, the automatic detection equipment does not need to reserve a large space for avoiding the action range of the feeding and discharging mechanism, so that the detection equipment is more compact, and the unit area output rate is improved.

Further, in an embodiment of the present application, the detection module may include a flipping cylinder, and the flipping cylinder may drive the detection module to flip 90 ° relative to the bracket (the detection module, the flipping cylinder, and the like will be described in more detail in conjunction with other embodiments below). In this way, the detection module can be turned 90 degrees, so that the detection module can be switched between a horizontal posture and a vertical posture. When the detection module is in a horizontal posture, the material changing mechanism can change the detection module, and when the detection module is in a vertical posture, the detection module and the target module at the corresponding position can jointly complete corresponding test items.

Further, still referring to fig. 2 and 3, in one embodiment of the present application, the bracket may include two posts, the detection module is mounted between the two posts, and each post is mechanically connected to the detection module by a single fastener. The design can enable the automatic detection equipment to achieve the technical effects of easiness in disassembly and maintenance. Specifically, in this embodiment, the detection module is arranged in the peripheral region of the turntable, and when a certain detection module breaks down, the fault detection module can be conveniently detached by only opening two fasteners and pulling out a cable plug on the back (or other positions) of the detection module, and then a new detection module is replaced, so that the operation of the detection device is quickly recovered. Therefore, the scheme of the embodiment reduces the fault interruption time, and further improves the production efficiency. Particularly, in a large-scale mass production (for example, mass production of tens of millions of scales), reducing the fault interruption time is very practical to improve the production efficiency.

Further, in an embodiment of the present application, in the automatic detection device, each detection module may have an AFC detection function, a DCC detection function, and an OTP burning function. Still referring to fig. 2, the OTP burning unit 116 can be directly fabricated on the detection module (of course, in another embodiment, the OTP burning unit 116 can be eliminated). And the AFC detection function and the DCC detection function need to be realized by matching with corresponding target modules. And each reticle module may be configured to be dedicated to one detection function. Based on the carousel of this embodiment, can rotate every detection module in proper order to the respective mark board module department that corresponds of AFC detection function and DCC detection function to realize AFC and DCC and detect. Moreover, each detection module has an AFC detection function, a DCC detection function and an OTP burning function, so that the camera module can complete all testing processes without being repeatedly placed on and taken out of the material carrying platform. In fig. 1, the number of the detection modules is four, but the application is not limited to this number. For example, the number of detection modules arranged along the periphery of the turntable can be five, six, etc. In another embodiment, each detection module may be responsible for detecting only one performance of the camera module.

Further, still referring to fig. 2, in one embodiment of the present application, the turntable 120 is disposed on a horizontal base 151, the horizontal base 151 has a flat surface, the base 151 can be disposed on a base frame 150 having a stable structure, and four legs of the base frame 150 can be placed on the ground. The base frame 150 adjusts the horizontal state of the upper surface of the base 151 by means of height adjusting devices located at the four legs, so that the flatness of the turntable can be ensured under acceptable installation conditions. In other words, the height variation in the Z-axis (i.e., vertical direction) direction of the detection module 110 on the turntable 120 is very small (i.e., within an error tolerance) as the turntable 120 rotates. In this embodiment, the turntable 120 has four brackets 130, and the four brackets 130 are respectively disposed at the trimming positions of the turntable 120. In particular, in the present embodiment, the trimming position of the turntable has four trimming slots 121, and one pillar of the bracket 130 is disposed on each of both sides of each trimming slot 121. The support 130 may support the detection module 110 at a height above the turntable 120. The upper ends of the two pillars of the bracket 130 may have openings, the pillar opening at one side of the detection module 110 may be disposed with a rotation bearing, and the pillar opening at the other side may be disposed with a turnover motor (the turnover motor may be replaced by a turnover cylinder, which is not described in detail below). The turning motor is connected with the detection module 110, and drives the detection module 110 to rotate around the rotating bearing, so that the material carrying platform 111 can be positioned at different angles. Furthermore, the overturning range can be 0-90 degrees through the limiting structure, so that the horizontal state and the vertical state are two stable states, and feeding and discharging and various tests are performed conveniently. Wherein, can go on unloading under the horizontal condition, can carry out each item test under the vertical condition. Note that, in the present embodiment, the flipping motor is a driving mechanism for driving the detection module 110 to rotate integrally (from the horizontal posture to the vertical posture or from the vertical posture to the horizontal posture), and is not a driving mechanism for driving the tool fixture to open and close the cover.

Further, in an embodiment of the application, the automatic detection equipment further includes a control device, which is used for controlling the rotation of the turntable and sequentially moving the plurality of test modules to the material changing station and each test station; and for any one test module, after the test module moves to the material changing station, the test module is turned to a horizontal posture, then all the tool fixtures of the test module are controlled to open the cover, the material changing mechanism is controlled to complete the material changing of the test module, all the tool fixtures of the test module are controlled to close the cover, the test module is turned to a vertical posture, and finally the turntable is controlled to rotate to sequentially move the test module to each test station for testing.

It should be noted that the material stage of the present application is not limited to the rotary integrated detection device. For example, to the integrated check out test set that each detection station is the linear type and arranges, or the single check out test set who is exclusively used in single detection link, the material microscope carrier of this application also can be suitable for. Through the safety light curtain, the material carrying platform can realize automatic material changing with low fault and high efficiency.

For example, in one embodiment of the present application, there is provided a material carrier adapted for automatic refuelling, comprising: installation face, at least one frock clamp, light curtain device and mechanism of reloading. The tooling clamp comprises a material carrier plate fixed on the mounting surface and a cover body connected with the material carrier plate through a pivot. The light curtain device is suitable for generating a light curtain parallel to the mounting surface, and the position of the light curtain is higher than that of the tool clamp in the fully opened state of the cover body. The material changing mechanism comprises a material taking head suitable for moving materials, wherein in the process of transverse translation of the material taking head, the material taking head and the materials taken by the material taking head are always higher than the light curtain. The material microscope carrier of this embodiment can realize the automatic reloading of low fault rate high efficiency, still has the advantage that occupies smallly simultaneously, is favorable to realizing the miniaturization of equipment. To the integrated check out test set that each detection station is linear type and arranges, perhaps be exclusively used in the single check out test set of single detection link, the material microscope carrier that is suitable for automatic reloading of this embodiment all can be suitable for.

The material microscope carrier of this application can also be applied to in the automated inspection or the production facility of other materials that are similar to the module of making a video recording to the efficient realization of low fault rate is automatic to be expected, and realizes the miniaturization of equipment. For example, the material may be other electronic device function modules to be detected. The electronic device may be any kind of consumer electronics terminal device, such as a smart phone, a tablet computer, a notebook computer, and so on. The electronic equipment function module is a module which can be arranged in the electronic equipment to complete a certain specific function of the electronic equipment. For example, the camera module, the structured light projection module, the TOF projection module (where TOF is called Time of Flight), the fingerprint identification module, and so on. These modules are generally small in size and inconvenient to transfer one by one in the production line, and are usually loaded in batches using trays (or called product boxes) and then transferred in the production line in units of whole trays. Also, these modules typically require a connector, which typically has a relatively dense array of contacts, to electrically connect to a motherboard of an electronic device (e.g., a cell phone) to allow the module to receive power and exchange data (e.g., output images). Before leaving the factory, the modules are usually subjected to power-on factory inspection to test the product performance and eliminate defective products. The material carrying platform is suitable for the detection equipment for the functional module of the electronic equipment, so that the automatic material changing with low failure rate and high efficiency is realized, and the miniaturization of the equipment (the detection equipment) is realized at the same time.

In the above embodiment, the tool clamp of the material carrier is an openable tool, and in the use process, the tool clamp needs to be opened first, the electronic device functional module to be detected is put in, and then the tool clamp is closed, so that subsequent detection can be performed. In the process of high-speed operation of automatic test equipment (such as integrated camera module automatic test equipment), the uncovering or closing state of the tool fixture is often required to be detected and state information is fed back to a control center, so that equipment faults caused by collision among different mechanisms or different modules in the equipment are avoided. Specifically, if the cover body of the tool clamp of the detection module is not opened in time or is completely opened, the automatic feeding and discharging mechanism carries out feeding and discharging actions, so that a suction nozzle of the feeding and discharging mechanism collides with the cover body of the clamp, equipment faults are caused, and the detection efficiency of the camera module is further influenced; because the speed that opens and shuts of frock lid is high, need carry out timely accurate judgement to the position of lid in the action process of automatic opening and shutting. Therefore, a device for accurately judging the position (opening angle) of the cover body in the high-speed automatic opening and closing operation of the tool and timely and accurately sending the position information to the control system for effective control is required to be developed, so that the device is matched with the automatic loading and unloading mechanism and the automatic detection device, and the detection efficiency of the mobile phone module is effectively improved.

The state detection device for the openable and closable tool will be described below with reference to a series of embodiments. The state detection device can be matched with the material carrying platform suitable for automatic material changing and corresponding automatic module testing equipment for use, so that the position (opening angle) of the clamp cover body which opens and closes at a high speed can be accurately judged, the feeding and discharging actions of the suction nozzle of the feeding and discharging mechanism can be accurately controlled, and the high-efficiency detection of the camera module is realized.

According to an embodiment of the application, a state detection device for an openable and closable tool is provided, and the state detection device is particularly suitable for an openable and closable tool for testing a functional module (such as a camera module) of electronic equipment. Fig. 10 is a schematic perspective view illustrating an openable and closable tool and a driving device thereof according to an embodiment of the present application. In this embodiment, the tool can be applied to, for example, a camera module detection device. Fig. 11 is a schematic view showing an openable and closable tool and a driving device thereof in an uncapped state according to an embodiment of the present application. Fig. 12 shows a schematic diagram of an openable and closable tool and a driving device thereof when the tool is in a closed state according to an embodiment of the present application. Fig. 13 shows a schematic diagram of an openable and closable tool provided with a blocking piece and a photoelectric switch circuit board and a driving device thereof in one embodiment of the present application. Fig. 14 is a schematic diagram illustrating a position relationship between the blocking sheet and the photoelectric switch element in an embodiment of the present application. Specifically, referring to fig. 10 to 14, in this embodiment, the tool 1001 includes a carrier 1100 and a cover 1200, where the carrier 1100 has two material carrying positions. In other embodiments, each tool may have only one material carrying location, or three or more material carrying locations. In this embodiment, the material can be the module of making a video recording. To traditional frock that is used for carrying the module of making a video recording, adopt the artifical mode that uncaps to close the lid to go up unloading usually. In the embodiment, the automatic opening and closing of the tool is realized based on the opening and closing driving device. The state detection device provided by the embodiment is mainly used for detecting the opening and closing state of the tool and outputting a state signal representing the opening and closing state of the tool in time, so that the tool is matched with other mechanisms (such as a feeding and discharging mechanism or other feeding and discharging mechanisms) in a cooperation manner in the high-speed opening and closing process, and feeding and discharging work is completed fully automatically and efficiently. Specifically, the state detection device of the present embodiment may include: an opening and closing driving device 2000, a baffle plate 3000 and a photoelectric switch circuit board 4000. The opening and closing driving device 2000 may include a moving part and a stationary part, wherein the moving part is connected to the cover 1200 and is used to drive the cover to open and close. The static part of the opening and closing driving device and the carrier of the tool can be fixed at the static end. The stationary end may be a stationary platform or may be other forms of stationary components. The moving part of the opening and closing driving device can reciprocate relative to the static part. In the present embodiment, the opening/closing state information of the cover 1200 is obtained by detecting the start point and the end point of the stroke of the moving member for driving the cover 1200 (here, the start point and the end point of the stroke are both end points of the linear movement stroke of the moving member), and therefore, the opening/closing driving device 2000 can be regarded as a part of the state detection device. Further, a stopper 3000 may be mounted to the moving member. Specifically, the stopper 3000 may be installed on a member connected to a piston of the opening and closing driving means and linearly reciprocated along with the piston. The optoelectronic switch circuit board 4000 may include a circuit board 4100 and an optoelectronic switch element 4200, the back surface of the circuit board 4100 may be mounted on the stationary part, the optoelectronic switch element 4200 may be mounted on the front surface of the circuit board 4100, the blocking piece 3000 may move to a position where the optoelectronic switch element 4200 is located along with the moving part and block the optoelectronic switch element 4200, the circuit board 4100 may output a status signal when the optoelectronic switch element 4200 is blocked, and the status signal may be used to indicate that the cover is opened or closed, so as to achieve a function of accurately detecting (for example, compared to a conventional magnetic position sensor-based) the open/close status of the tool. For example, assuming that the tool 1001 is in the closed state at the stroke start point of the moving member, the position where the stopper 3000 is disposed may be: the shutter just blocks the position of the optoelectronic switch element 4200 when the moving part is at the beginning of the stroke. Thus, when the moving part moves to the stroke starting point each time, the photoelectric switch circuit board 4000 can output a cover closing completion signal. Similarly, assuming that the tool 1001 is at the maximum uncapping position (i.e., uncapping to the set maximum angle) at the end of the stroke of the moving member, the set position of the shutter 3000 may be: the shutter 3000 just blocks the position of the photoelectric switch element 4200 when the moving member is located at the end of the stroke. Therefore, when the moving part moves to the stroke end every time, the photoelectric switch circuit board can output a cover opening completion signal. The movement of the moving part can be reciprocating movement, namely reciprocating movement between a stroke starting point and a stroke end point, so that the actions of opening and closing the cover are repeated continuously, and the detection device can also continuously output an opening and closing state signal corresponding to the clamp. The output opening and closing state signal can be matched with an automatic loading and unloading mechanism, so that automatic loading and unloading of the mobile phone module are completed, and full-automatic detection of the mobile phone module is further facilitated.

Further, in an embodiment of the present application, the opening and closing driving device 2000 is a cylinder driving device. The stroke start and end may be understood as the start and end positions of the reciprocating motion of the piston in the cylinder. The cylinder may include a cylinder 2100, a piston 2200, and a transmission mechanism. The cylinder 2100 may be filled with and discharged from gas, and the piston 2200 may be driven to reciprocate in the cylinder 2100 by the filling and discharging of the gas. Both the piston 2200 and the transmission mechanism are moving parts. Wherein the piston 2200 is located inside the cylinder 2100. The transmission mechanism may include a piston rod 2300 and a crank rod 2400, one end of the piston rod 2300 is connected to the piston 2200, and the other end thereof extends out of the cylinder 2100. One end extending out of the cylinder 2100 may be connected to a crank link 2400 outside the cylinder. One end of the crank rod 2400 is fixed to the piston rod 2300, and the other end is connected to the cover 1200. The stopper 3000 is attached to the crank link 2400. Preferably, the crank link 2400 includes a support rod 2410 and a driven rod 2420, the support rod 2410 is pivotally connected to the piston rod 2300, the driven rod 2420 is pivotally connected to the other end of the support rod 2410, and the driven rod 2420 is pivotally connected to the support rod 2410 and the other end of the driven rod 2420 is connected to the cover 1200. Specifically, a protruding structure 1210 may be provided at the root of the cover body, and the driven rod 2420 may be connected to the protruding structure 1210 (refer to fig. 10). . The blocking piece 3000 is installed on the supporting rod 2410. The back surface of the circuit board 4100 of the photoelectric switch circuit board 4000 may be mounted on the outer surface of the cylinder 2100 (or a mounting base may be fixed to the outer surface of the cylinder, and then the back surface of the circuit board may be supported and fixed on the mounting base, and in this case, the mounting base may be regarded as a part of the stationary member). In this embodiment, the photoelectric switch circuit board 4000 and the blocking plate 3000 that is photo-sensitive to the photoelectric switch are disposed outside the cylinder, so that the inherent structure of the cylinder itself can be directly utilized without changing the structure and operation mode of the cylinder itself, which is very advantageous particularly for a small-sized cylinder. In this embodiment, the sensor and other components (e.g., the blocking plate) added for state detection are installed outside the cylinder, so that the present embodiment can effectively avoid many problems (e.g., how to arrange the wires, how to ensure airtightness, how to reduce occupied space, etc.) caused by installing the sensor inside the cylinder, thereby making the cylinder itself simple in structure, convenient for installation, maintenance and replacement, low in cost, and small in occupied space. On one hand, the blocking pieces and the photoelectric switch circuit board are both in a sheet shape or a thin plate shape, the blocking pieces and the photoelectric switch circuit board are suitable for being inserted into gaps between adjacent tools, and the tools are arranged in an array manner, so that a material carrying platform and a detection module which are compact in structure are formed, and the occupied size is reduced. On the other hand, separation blade 3000 and photoelectric switch circuit board 4000 are external, can make cylinder simple structure itself, also are favorable to reducing the volume. Generally speaking, electronic device modules such as camera modules need to be produced and inspected in a highly clean environment, and the cost of the factory building is high, and people expect to improve the yield per unit area as much as possible. Therefore, the yield per unit area of the module inspection equipment is an important evaluation index. This requires that the module detection device be as compact as possible. Therefore, the installation space of the material carrying platform and the detection module of the module detection equipment (such as mobile phone camera module detection equipment) is very limited. On the other hand, a single module detection device sometimes integrates a plurality of detection modules so as to detect a plurality of different items at the same time, and the highly integrated design also requires that the size of the tool for carrying the module and the attached structure thereof be reduced as much as possible, and the design of the embodiment can effectively solve the problems.

In the testing of functional modules of electronic devices, especially in the testing of precision optical devices such as camera modules, testing equipment is generally required to provide better protection for the tested modules so as to avoid the quality degradation and even rejection of the modules caused by collision, contamination or other reasons. Therefore, the tooling of the testing equipment needs to cover the camera module. In order to realize miniaturization of automatic production equipment and improve testing efficiency, the cover body and a mechanism for moving the cover body need to be prevented from occupying more space, and a module carrying platform and a material taking and placing mechanism in the testing equipment are compactly configured, so that the stroke of loading and unloading of the module is reduced; moreover, through reducing module carrying platform and getting the distance of putting between the material control mechanism (especially reduce the difference in height between material ingestion head and the module carrying platform), help reducing the space that slider and guide rail occupy, can also improve the module simultaneously and place the precision in carrying the platform, avoid placing the inaccurate unable normal electric connection scheduling problem that leads to because of the displacement distance causes the module greatly in carrying the platform. Fig. 16 is a schematic diagram illustrating a positional relationship between the material taking and placing mechanism and the openable and closable tool and the driving device thereof in a state where the cover is incompletely opened in one embodiment of the present application. Referring to fig. 16, it can be seen that the height difference between the material pick-up head 310 (or the guide rail 330) and the module carrying platform (i.e. the fixture) is very small, and at the preset uncovering angle, the material pick-up head and the module picked up by the material pick-up head just can get over the highest point of the cover 1200 in the completely uncovered state of the fixture. Because material absorbs head (or guide rail) and module and carries on the platform and have less difference in height, consequently after the translation of material absorbing head to module carries on the platform top, only need descend (promptly) less distance down, can place the module on module carries on the platform (the carrier of frock). The material ingestion head usually combines with the guide rail through the slider, if the required lift distance of material ingestion head is great, in order to guarantee mechanical stability, its slider and guide rail often also need to carry out corresponding improvement, and this just leads to getting drop feed mechanism's occupation space increase. Therefore, the distance between the module carrying platform and the material taking and placing control mechanism is reduced, the occupied space of the material taking and placing mechanism can be reduced, and the miniaturization of module detection equipment is facilitated. In this embodiment, based on the cooperation of separation blade 3000 and photoelectric switch circuit board 4000, can realize the accurate detection to the lid state of opening and shutting, this collision that has just avoided because of the frock is uncapped incompletely and is leaded to. While the cover position 1290 is shown in fig. 16 in the incomplete-uncapping state, it can be seen that if the tooling is incompletely uncapped, the material pick-up head 310 or material it picks up (e.g., module 3300) may collide with the cover (e.g., the cover at cover position 1290).

Furthermore, in the embodiment, a small air cylinder with a simple structure can be configured for each tool to serve as a driving device for driving the cover body to open and close, so that the miniaturization of equipment is facilitated, and the testing efficiency is improved. In addition, because the cover body for protecting the camera module needs to be frequently opened and closed in the process of rapid testing, the position/state of the cover body needs to be accurately judged and accurately matched with the material taking and placing control mechanism, and therefore equipment production halt caused by collision of the cover body and the material taking and placing control mechanism in the feeding and discharging process is avoided. The photoelectric switch element and the corresponding baffle are arranged to shield the photoelectric switch element at a specific position (corresponding to the fully opened position of the cover body, for example) through the baffle so as to form a sensing signal, so that the position (opening angle) or the state (opening or closing) of the cover body can be accurately measured, and the cover body is matched with the material taking and placing control mechanism so as to avoid collision between the material taking and placing control mechanism and the cover body. Because module test equipment's action speed is very fast, for example the frock is opened from the lid, is accomplished to get and puts to the lid and closes probably to be accomplished in the very short time, and gets the distance of material intake head and the frock of expecting control mechanism and be very close (the position of material intake head and frock is very close, is on the one hand for shortening the operation route of material intake head, on the other hand is for improving the efficiency of the automatic unloading of module), general position sensor is difficult to satisfy the requirement in the aspect of the precision. Taking the magnetic sensor as an example, based on the principle of magnetic field induction, a magnetic induction signal may be generated when an object to be measured approaches and does not actually reach a measurement point, which may result in an inaccurate measurement result. Compare in other position sensor products on the market, the advantage of the circuit board based on photoelectric switch element of this embodiment lies in that its precision and reliability are higher, response speed is faster, the interference killing feature is stronger, can satisfy the requirement of the moment of accurate judgement object arrival position to be measured.

Further, in an embodiment of the present application, the optoelectronic switch element includes a first optoelectronic switch element and a second optoelectronic switch element, when the blocking piece blocks the first optoelectronic switch element, the circuit board outputs a state signal for representing that the cover opening is completed, and when the blocking piece blocks the second optoelectronic switch element, the circuit board outputs a state signal for representing that the cover closing is completed. Preferably, the blocking piece includes a first blocking piece for blocking the first photoelectric switch element and a second blocking piece for blocking the second photoelectric switch element. By providing two photoelectric switching elements and two corresponding blocking pieces, the moment when the cover body is completely opened and the moment when the cover body is completely closed can be determined and correspondingly controlled. For example, when the first blocking piece blocks the first photoelectric switch element, the first photoelectric switch element sends an induction signal to the controller, and the controller controls the material intake head of the material taking and placing mechanism to move towards the tool according to the received induction signal so as to carry out material taking and placing operations; when the second blocking piece shields the second photoelectric switch, the second photoelectric switch element sends a sensing signal to the controller, and the controller starts subsequent module testing operation according to the received sensing signal. It should be noted that, in the present application, when the state detection device only needs to output the cover opening completion signal, or only needs to detect the cover closing completion signal, the state detection device may only have one blocking piece and one photoelectric switch element. When the state detection device needs to output two signals, namely, the cover opening completion signal and the cover closing completion signal, the state detection device can be provided with two blocking pieces and two photoelectric switch elements. If the shape and the position of the blocking piece are reasonable in design, the blocking piece and the two photoelectric switch elements can be used for outputting a cover opening completion signal and a cover closing completion signal, the blocking piece is arranged at the position capable of blocking the first photoelectric switch element at the stroke starting point, and the blocking piece can be moved to the position just blocking the second photoelectric switch element at the stroke end point, so that the first photoelectric switch element and the second photoelectric switch element can timely output the two signals of the cover opening completion signal and the cover closing completion signal. On the other hand, in the present embodiment, the optoelectronic switch circuit board may have an LED lamp thereon, and the LED lamp may serve as a status signal indicator lamp. Therefore, if the safety of equipment operators and the cleanliness of equipment are considered, when the openable tool and the auxiliary mechanical device thereof are arranged in the box body, an operator can judge the current opening and closing state of the tool by observing the condition of the indicator lamp.

Further, in this embodiment, when various parameters of the tool, such as the speed of opening and closing the cover, the pressure applied to the module by the cover closing action, the maximum opening angle, and the like, need to be adjusted, the installation position of the baffle can be adjusted in an adaptive manner by only changing the size of the air flow introduced into the air cylinder, and further adjustment of control programs of other mechanisms of the detection equipment, such as the material taking and placing mechanism, is not needed. Therefore, the present embodiment can greatly facilitate the debugging of the tool to achieve the optimal state.

Referring to fig. 10, it is preferable that the cover body 1200 has a protruding structure 1210 at a root, and the driven lever 2420 is connected to the cover body 1200 through the protruding structure 1210, wherein the cover body 1200 and the carrier 1100 are pivotally connected through a pivot, and the root is a portion of the cover body 1200 close to the pivot.
