Description

Technical Field

[0006]

[0001] The present invention relates to the technical field of article transportation, and particularly to a clamp jaw device.

Background Art

[0002] A wafer is a basic raw material for manufacturing semiconductor devices. Ultra-high purity semiconductors are processed into wafers through processes such as pulling and slicing. Wafers are formed into extremely minute circuit structures through a series of semiconductor manufacturing processes, and then become IC chips through cutting, sealing, and testing. They are widely applied in various electronic equipment.

[0003] During the semiconductor manufacturing process, an IC chip needs to go through multiple operating stages. To ensure the safety during the operating stages of the IC chip, the IC chip is stored in a material case (magazine) during storage and transportation to ensure the stability during the transportation process of the IC chip.

[0004] During the operating stage, a clamp jaw is often used to grasp the material case. The clamp jaw transports the material case to a designated position under the drive of a robot arm. The material case has openings at both ends, and the IC chip is placed inside the material case through the openings. The clamp jaw directly sandwiches two side walls of the material case that do not have openings. When the control of the clamping force of the clamp jaw is inappropriate, if the clamping force is too large, it will cause physical damage to the metal surface of the material case. If the clamping force is too small, the material case cannot be stably clamped, causing the center of gravity of the material case to shift and tilt, resulting in the IC chip slipping off from the opening. In severe situations, the material case will directly fall off, causing damage to all of the material case and the IC chip.

[0005] Therefore, how to provide a clamp jaw with strong stability is a technical problem that needs to be urgently solved by those skilled in the art.

Summary of the Invention

[0006] To solve the problems of the prior art, the present invention provides a clamp jaw device and solves one or more technical problems that exist in the prior art. A clamp jaw device used for clamping a housing, wherein the housing includes a top plate provided with at least two lifting members, the lifting members include a recessed structure, and the clamp jaw device includes the following: At least two clamp jaw units, each of which includes a projection structure, the projection structure engages with the recess structure. The clamp jaw unit moves along a direction toward the lifting member, causing the projection structure and the recess structure to interlock and come into contact to form an engagement structure, or moves along a direction toward away from the lifting member, causing the projection structure and the recess structure to separate and release the engagement structure. In this design, the protruding structure on the clamp jaw unit and the recessed structure of the lifting member on the top plate of the housing are designed to fit together in a complementary manner. This tightens the two structures to form an engaging structure, ensuring stable clamping of the housing. This protects the contents of the housing from damage during transport and simultaneously avoids problems such as damage to the housing due to improper clamping force or the contents slipping out of the housing.

[0007] The clamp jaw device may also include a main controller. The projection structure includes a main body, a pressing structure, and a transmission structure and a microswitch installed inside the main body. The main body has a notch on one side, the pressing structure aligns with the notch, and the pressing structure is connected to the transmission structure. In the first state, the pressing structure moves from the notch to the pressing position along a direction away from the main body, and the pressing position is located on one side of the recessed structure (1010). In the second state, the projection structure moves toward the recess structure, bringing the pressing structure and the recess structure into contact. The pressing structure moves along the direction toward the main body, complementing the notch and becoming integrated, so that the projection structure and the recess structure interlock and come into contact to form an engagement structure. When the pressing structure is integrally fitted with the notch, the pressing structure applies an external force to the microswitch via the transmission structure, and when the microswitch is activated, a lock signal is transmitted to the main controller, and the lock signal indicates that the clamp jaw device and the housing are engaged.

[0008] In the first state, or initial state, the pressing structure is not fitted into the main body but extends naturally outside the main body. In the second state, or engagement operation, the pressing structure first engages with and contacts the recessed structure, is pushed back into the notch under the action of an external force, and becomes one with the notch in a complementary manner. Furthermore, the protruding structure and the recessed structure engage and abut against each other to form an engagement structure, stably engaging the clamp jaw unit and the lifting component, and improving the stability of the clamp jaw device.

[0009] The clamp jaw device further includes a sliding mechanism, the sliding mechanism may include a sliding rail and a sliding table mounted on the sliding rail. The clamp jaw unit is connected to the slide table and moves along the slide rail by the slide table in a direction toward or toward the lifting member. In this process, the sliding mechanism is installed by moving two clamp jaw units closer together or further apart, thereby engaging the protruding structure and the recessed structure to form an engagement structure, or by separating the protruding structure and the recessed structure to cut them apart.

[0010] The clamp jaw device may further include a drive mechanism, which is connected to one end of the clamp jaw unit that is far from the projection structure, and which moves the clamp jaw unit on the slide rail by the slide table. The drive mechanism then provides power to move the clamp jaw unit, causing it to move along the slide rail.

[0011] The clamp jaw device may further include a baffle plate and at least one first sensor mechanism. The first sensor mechanism is provided below the clamp jaw unit along the height direction and includes a first optical signal emitter and a first optical signal receiver, the first optical signal emitter being used to emit an optical signal and the first optical signal receiver being used to receive the optical signal. The baffle plate is provided at the bottom of the clamp jaw unit along the height direction, and when the projection structure and the recess structure interlock and contact to form an engagement structure, the baffle plate is positioned between the first optical signal emitter and the first optical signal receiver, blocking the path of the optical signal, the first sensor mechanism transmits a termination signal to the main controller, and the main controller controls the stopping of operation of the drive mechanism based on the termination signal. When the protruding and recessed structures interlock to form an engaging structure, the clamp jaw unit is already tightened against the lifting member. However, if the drive mechanism still does not stop operating, the clamp jaw unit continues to move toward the lifting member. In this gripping state, continuous pressure from the clamp jaw unit against the lifting member is likely to cause damage to both the clamp jaw unit and the lifting member. Therefore, a baffle plate is used to block the optical signal path of the first sensor mechanism, and the first sensor mechanism transmits a termination signal to the main controller, thereby stopping the operation of the drive mechanism and preventing damage to itself and the lifting member due to the continuous movement of the clamp jaw unit.

[0012] The clamp jaw device further includes at least two second sensor mechanisms, each of which is installed in close proximity to the clamp jaw unit and includes a second optical signal emitter and a second optical signal receiver, wherein the second optical signal emitter emits a detection signal in the direction of the lifting member, and the second optical signal receiver is used to receive a reflected signal formed when the detection signal is incident on the lifting member. The second sensor mechanism transmits the reflected signal to the main controller, and the main controller determines, based on the reflected signal, whether the angle between the transmission path of the detection signal and the plane on which the lifting member is located maintains a predetermined angle. When a predetermined angle is maintained, it is determined that the relative position between the lifting member and the clamp jaw unit conforms to a predetermined standard, and the clamp jaw unit is controlled to move in a direction approaching the lifting member. The second sensor mechanism is used to detect whether the housing is in the correct position. If it is not in the correct position, there is a possibility that the clamp jaw unit may not be securely fixed to the lifting member. Therefore, the main controller controls the clamp jaw unit to move toward the lifting member and fix it to the lifting member only when the relative position of the lifting member and the clamp jaw unit conforms to a predetermined standard.

[0013] The clamp jaw device further includes a casing, the casing including a housing cavity and a mounting opening. The drive mechanism is provided on the side of the housing cavity away from the mounting opening, and the slide mechanism is provided on the side of the housing cavity close to the mounting opening. The portion connecting the clamp jaw unit, the drive mechanism, and the slide mechanism is located within the housing cavity, while the other portions may extend outside the casing, passing through the mounting opening in a direction away from the housing cavity. In addition, installing a casing provides mounting space for the drive mechanism and sliding mechanism, protecting the safety of the mechanism. This prevents damage to the internal mechanism even if the clamp jaw device collides with the outside while performing a gripping operation.

[0014] The clamp jaw unit includes a first plate member, a second plate member, and a third plate member connected in sequence, wherein the first plate member is connected to the drive end of the drive mechanism, the bottom end of the first plate member is connected to the slide table, one end of the second plate member is connected to the end of the first plate member away from the drive end, and the other end extends outside the casing through the mounting opening in a direction away from the housing cavity and is connected to the third plate member, and the projection structure may be provided on the end of the third plate member away from the second plate member. Of these, the first and third plate members can be installed parallel to each other, which facilitates the drive mechanism's movement of the clamp jaw unit. Installing the second plate member allows for adjustment of the step between the clamp jaw device and the housing, improving the adaptability of the clamp jaw device.

[0015] The housing may include at least one opening, through which the article is housed within the housing. The clamp jaw device further includes at least one shielding mechanism, which is installed on the outer wall of the casing, and when the projection structure and the recess structure engage and come into contact, the shielding mechanism moves to the opening and comes into contact with the end face of the housing having the opening, preventing the article from falling out of the housing through the opening. When the clamp jaw device grips the housing, the presence of an opening in the housing means that if the housing is subjected to external forces, vibration and shaking can occur, causing items inside the housing to fall out through the opening. The shielding mechanism shields the opening side of the housing and makes close contact with the housing structure, preventing items from falling out through the opening and ensuring the safety of items stored inside the housing.

[0016] The shielding mechanism includes a movable rod member, a shielding member, and a movable connecting member. One end of the movable rod member is connected to the casing, and the other end is connected to the shielding member by the movable connecting member, and the movable connecting member may be used to mitigate the reaction force from the housing on the shielding member when the shielding member comes into contact with it. When the shape of the housing matches a predetermined shape, the shielding member comes into contact with the end face of the housing having an opening, the movable connecting member is in a natural state, and a first predetermined angle is maintained between the movable rod member and the shielding member. When the shape of the housing does not match the predetermined shape, the shielding member abuts against the end face of the housing having an opening, the movable connecting member is in an extended state, and a second predetermined angle is maintained between the movable rod member and the shielding member. Of these, the second predetermined angle is greater than the first predetermined angle. Among these, different types of housings have different sizes. For housings that are relatively small and conform to a predetermined shape, the shielding member can just abut against the end face of the housing that has the opening when it moves into the opening. For housings that are relatively large and do not conform to a predetermined shape, the shielding member is expanded by the end face of the housing that has the opening when it moves into the opening, and the movable connecting member is in an expanded state. This reduces the reaction force from the housing on the shielding member when it abuts against it, avoids damage to the shielding member, and enables application to various types of housings.

[0017] The embodiments provided by the present invention bring about the following technical effects. The present invention provides a clamp jaw device for use in clamping a housing. The housing includes a top plate provided with at least two lifting members, the lifting members include a concave structure, and the clamp jaw device includes at least two clamp jaw units. The clamp jaw unit includes a protrusion structure, and the protrusion structure and the concave structure are complementary. The clamp jaw unit moves in a direction approaching the lifting member, and engages the protrusion structure and the concave structure in abutment to form an engagement structure. In this solution, through the complementary fitting design of the protrusion structure on the clamp jaw unit and the concave structure of the lifting member on the top plate of the housing, the two are clamped to form an engagement structure, realizing a stable grip on the housing. Thereby, it prevents the articles in the housing from being damaged during the transportation process, and avoids the problems of damage to the housing due to inappropriate gripping force or slipping of the articles from the housing.

Embodiments for Implementing the Invention

[0019] Hereinafter, some embodiments of the present invention will be described with reference to the drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention and do not limit the protection scope of the present invention.

[0020] As described in the background art, in the transportation process, the material case is often gripped using gripping claws, and the gripping claws are driven by a robot arm to transport the material case to a specified position. The material case has openings at both ends, the IC chip is housed inside the material case through the openings, and the gripping claws directly grip two side walls of the material case that do not have openings. If the control of the gripping force of the gripping claws is inappropriate, if the gripping force is too large, it may cause physical damage to the metal surface of the material case. If the gripping force is too small, the material case cannot be stably gripped, the center of gravity of the material case shifts and tilts, causing the IC chip to slide off from the opening. In severe cases, the material case directly falls off, causing damage to the entire material case and IC chip.

[0021] The present invention provides a clamp jaw device that securely tightens the housing. Referring to the overall schematic diagram of the clamp jaw device shown in Figure 1 and the schematic diagrams of the projection structure and recess structure shown in Figure 2, the clamp jaw device is used to clamp the housing 10. The housing 10 includes a top plate 100 provided with at least two lifting members 101, and the lifting members 101 include recess structures 1010. The clamp jaw device includes at least two clamp jaw units 20. Each clamp jaw unit 20 includes a projection structure 200, which is fitted into the recess structure 1010. The clamp jaw unit 20 moves in a direction approaching the lifting member 101, causing the projection structure 200 and the recess structure 1010 to interlock and contact to form an engagement structure 30, or moves in a direction away from the lifting member 101, separating the projection structure 200 and the recess structure 1010 to release the engagement structure 30. In this configuration, the complementary fitting design of the projection structure 200 on the clamp jaw unit 20 and the recess structure 1010 of the lifting member 101 on the top plate 100 of the housing tightens them together to form an engagement structure 30, thereby achieving a stable grip on the housing 10. This prevents damage to the items inside the housing 10 during transport and avoids damage to the housing 10 due to inappropriate gripping force, as well as the problem of items slipping off the housing 10.

[0022] In one embodiment of the present invention, there are two lifting members 101, maintaining a predetermined distance between them, and their recessed structures 1010 are positioned opposite each other. There are also two clamp jaw units 20, initially positioned between the two lifting members 101, with their projection structures 200 facing the recessed structures 1010. When performing a gripping operation, the two clamp jaw units 20 move away from each other, each moving toward the corresponding lifting member 101, and engaging one projection structure 200 with the recessed structure 1010 to form an engagement structure 30. The engagement of the projection structure 200 and the recessed structure 1010 allows the clamp jaw unit 20 to securely grip the housing 10, reducing the risk of the article slipping or the housing 10 being damaged due to gripping instability during the transport process. At the same time, the clamp jaw unit 20 considers the equilibrium distribution of force, and the symmetrical movement of the two clamp jaw units 20 ensures a uniform distribution of force during the gripping process, avoiding tilting of the article or deformation of the housing 10 due to uneven force. In one embodiment of the present invention, the clamp jaw device can be adapted to housings 10 of different dimensions and shapes. By installing appropriate lifting members 101 and recessed structures 1010 on the top plate 100 of the housing 10, the clamp jaw unit 20 can perform a rapid gripping operation, achieve stable gripping, improve operational efficiency, and reduce the complexity of manual operation.

[0023] Preferably, referring to the schematic diagrams of the projection and recessed structures shown in Figure 2 and the schematic diagrams of the first and second states shown in Figures 3 and 4, the clamp jaw device further includes a main controller (not shown). The projection structure 200 includes a main body, a pressing structure 201, and a transmission structure 202 and a microswitch 203 installed inside the main body. A notch 40 is provided on one side of the main body, the pressing structure 201 complements the notch 40, and the pressing structure 201 is connected to the transmission structure 202. In the first state, the pressing structure 201 moves along the direction away from the main body from the notch 40 to the pressing position, and the pressing position is located on one side of the recessed structure 1010. In the second state, the projection structure 200 moves toward the recess structure 1010, bringing the pressing structure 201 into contact with the recess structure 1010. The pressing structure 201 then moves toward the notch 40 along the direction approaching the main body, engaging integrally with the notch 40, and interlocking the projection structure 200 with the recess structure 1010 to form the engagement structure 30. When the pressing structure 201 engages integrally with the notch 40, the pressing structure 201 applies an external force to the microswitch 203 via the transmission structure 202. When the microswitch 203 is activated, it transmits a lock signal to the main controller, which indicates that the clamp jaw device and the housing 10 have completed engagement. In the first state, or initial state, the pressing structure 201 is not fitted into the main body and protrudes naturally outside the main body. In the second state, or during gripping operation, the pressing structure 201 first engages with and contacts the recessed structure 1010, is pushed back into the notch 40 by the action of an external force, and becomes one with the notch 40 through mutual complementarity. Furthermore, the projection structure 200 and the recessed structure 1010 engage and come into contact to form an engagement structure 30, which stably tightens the clamp jaw unit 20 and the lifting member 101, improving the stability of the clamp jaw device.

[0024] In one embodiment of the present invention, when the projection structure 200 and the recess structure 1010 separate, the pressing structure 201 separates from the notch 40 and is positioned to protrude along the direction away from the notch 40 and the main body, returning to the first state, i.e., the initial state position. In one embodiment of the present invention, in the first state, a certain distance is maintained between one end of the transmission structure 202 away from the pressing structure 201 and the microswitch 203. When the pressing structure 201 becomes integral with the notch 40 in a complementary manner, the transmission structure 202 comes into contact with the microswitch 203, and a lock signal is generated.

[0025] Preferably, referring to the schematic diagram of the drive mechanism, slide mechanism, and clamp jaw unit connections shown in Figure 6, the clamp jaw device further includes a slide mechanism, which includes a slide rail 50 and a slide table 51 mounted on the slide rail 50. The clamp jaw unit 20 is connected to the slide table 51, and the slide table 51 moves along the slide rail 50 in a direction toward or toward the lifting member 101. By installing a sliding mechanism, the two clamp jaw units 20 can be brought closer together or separated, causing the projection structure 200 and the recess structure 1010 to interlock and form an engagement structure 30, or the projection structure 200 and the recess structure 1010 to separate and release the engagement, thereby improving operational flexibility.

[0026] In one embodiment of the present invention, the slide rail 50 employs a linear ball-type guide slide rail having a linearity accuracy of up to 1 μm, thereby achieving high-precision sliding. In one embodiment of the present invention, the sliding mechanism may be installed above or below the clamp jaw unit 20. In one embodiment of the present invention, the sliding mechanism can achieve long-stroke sliding by a chain structure, allowing the clamp jaw unit 20 to move for a longer distance and adapt to a wider range of motion.

[0027] Preferably, referring to the schematic diagram of the connection of the drive mechanism, slide mechanism, and clamp jaw unit shown in Figure 6, the clamp jaw device further includes a drive mechanism 60 connected to one end of the clamp jaw unit 20 away from the projection structure 200 in order to move the clamp jaw unit 20 on the slide rail 50 by the slide table 51. By installing the drive mechanism 60, power is supplied for the clamp jaw unit 20 to move along the slide rail 50.

[0028] In one embodiment of the present invention, the drive mechanism 60 employs a servo motor that provides precise speed and position control. In one embodiment of the present invention, the drive mechanism 60 employs a stepping motor that provides a precise step speed in order to precisely control the opening and closing position of the clamp jaw unit 20. In one embodiment of the present invention, the drive mechanism 60 employs a hydraulic cylinder or a pneumatic cylinder, and the gripping portion is opened and closed by the transmission of a rack and pinion mechanism, thereby enabling the clamp jaw unit 20 to move closer to or further away from each other.

[0029] Preferably, the clamp jaw device further includes a baffle plate (not shown) and at least one first sensor mechanism (not shown). The first sensor mechanism is located below the clamp jaw unit 20 along the height direction and includes a first optical signal emitter (not shown) and a first optical signal receiver (not shown), the first optical signal emitter being used to emit an optical signal and the first optical signal receiver being used to receive an optical signal. The baffle plate is located at the bottom of the clamp jaw unit 20 along the height direction, and when the projection structure 200 and the recess structure 1010 interlock and contact to form an engagement structure 30, the baffle plate is located between the first optical signal emitter and the first optical signal receiver, blocking the optical signal path, the first sensor mechanism transmits a termination signal to the main controller, and the main controller controls the stopping of operation of the drive mechanism 60 based on the termination signal. When the projection structure 200 and the recess structure 1010 interlock to form the engagement structure 30, the clamp jaw unit 20 is already tightened against the lifting member 101. However, if the drive mechanism 60 does not stop operating, the clamp jaw unit 20 continues to be driven toward the lifting member 101. In this gripping state, continuous pressure applied by the clamp jaw unit 20 to the lifting member 101 is likely to cause damage to both the clamp jaw unit 20 and the lifting member 101. Therefore, a baffle plate is used to block the optical signal path of the first sensor mechanism, and the first sensor mechanism transmits a termination signal to the main controller, thereby stopping the operation of the drive mechanism and preventing damage to itself and the lifting member 101 due to the continuous movement of the clamp jaw unit 20.

[0030] In one embodiment of the present invention, the first sensor mechanism uses an optical signal sensor. In one embodiment of the present invention, the baffle plate has a plate-like rectangular parallelepiped structure, and when the baffle plate crosses the optical signal path, the optical signal path is perpendicular to the baffle plate.

[0031] Preferably, referring to the schematic side cross-sectional view of the inside of the casing shown in Figure 5, the clamp jaw device further includes at least two second sensor mechanisms 70 installed in close proximity to the clamp jaw unit 20, each second sensor mechanism 70 including a second optical signal emitter (not shown) for emitting a detection signal in the direction toward the lifting member 101, and a second optical signal receiver (not shown) for receiving a reflected signal formed when the detection signal is incident on the lifting member 101. The second sensor mechanism 70 transmits the reflected signal to the main controller, which determines, based on the reflected signal, whether the angle between the transmission path of the detection signal and the plane on which the lifting member 101 is located maintains a predetermined angle. If the predetermined angle is maintained, the main controller determines that the relative position between the lifting member 101 and the clamp jaw unit 20 conforms to a predetermined standard, and controls the clamp jaw unit 20 to move toward the lifting member 101. Of these, the second sensor mechanism 70 is used to detect whether the housing 10 is in the correct position. If it is not in the correct position, there is a possibility that the clamp jaw unit 20 will not be able to be securely tightened to the lifting member 101. For this reason, the main controller controls the clamp jaw unit 20 to move toward the lifting member 101 and tighten it with the lifting member 101 only when the relative position of the lifting member 101 and the clamp jaw unit 20 conforms to a predetermined standard. In one embodiment of the present invention, the second sensor mechanism uses an optical signal sensor.

[0032] Preferably, referring to the overall schematic diagram of the clamp jaw device shown in Figure 1 and the schematic side cross-sectional diagram of the inside of the casing shown in Figure 5, the clamp jaw device further includes a casing 80, which includes a housing cavity (not shown) and a mounting opening 800. The drive mechanism 60 is located on the side of the housing cavity away from the mounting opening 800, and the slide mechanism is located on the side of the housing cavity close to the mounting opening 800. The parts of the clamp jaw unit 20 that connect to the drive mechanism 60 and the slide mechanism are located inside the housing cavity, while the other parts extend outside the casing 80, passing through the mounting opening 800 in a direction away from the housing cavity. In addition, the installation of the casing 80 provides mounting space for the drive mechanism 60 and the sliding mechanism, thereby protecting the safety of the mechanism. This prevents damage to the internal mechanism even if the clamp jaw device collides with the outside while performing a gripping operation.

[0033] In one embodiment of the present invention, the casing 80 includes an upper plate 81, a lower plate 82, a side plate 83, a rear plate 84, and a front plate 85. These plate members surround each other to form the casing 80, and a housing cavity is formed inside the casing 80. A partition plate 86 is provided inside the housing cavity, dividing it into two parts, upper and lower. The drive mechanism 60 is mounted below the upper plate 81 and above the partition plate 86. The slide mechanism is located below the partition plate 86 and is installed close to the front plate 85. The first sensor mechanism is installed close to the slide mechanism, and the second sensor mechanism is located below the slide mechanism and is installed close to the front plate 85. The detection signal emitted by the second sensor mechanism passes through the signal port 850 of the front plate 85 and reaches the lifting member 101.

[0034] Preferably, referring to the schematic diagram of the connection of the drive mechanism, slide mechanism, and clamp jaw unit shown in Figure 6, the clamp jaw unit 20 includes a first plate member 21, a second plate member 22, and a third plate member 23 that are connected in sequence, forming a structure that approximates a "Z" shape. The first plate member 21 is connected to the drive end of the drive mechanism 60, the bottom end of the first plate member 21 is connected to the slide table 51, one end of the second plate member 22 is connected to the end of the first plate member 21 away from the drive end, and the other end extends outside the casing 80 through the mounting opening 800 in a direction away from the housing cavity and is connected to the third plate member 23, and a projection structure 200 is provided on the end of the third plate member 23 away from the second plate member 22. The clamp jaw unit 20 is designed to have a "Z" shape, with the first plate member 21 and the third plate member 23 installed parallel to each other. This facilitates the drive mechanism 60's movement of the clamp jaw unit 20 and optimizes the movement path of the clamp jaw unit 20. The installation of the second plate member 22 allows for adaptation to the step difference between the clamp jaw device and the housing 10, improving the adaptability of the clamp jaw device.

[0035] In one embodiment of the present invention, both ends of the second plate member 22 are perpendicular to the first plate member 21 and the third plate member 23, respectively. In one embodiment of the present invention, the connection between one end of the second plate member 22 and the first plate member 21 maintains a predetermined angle, and the connection between the other end and the third plate member 23 maintains a predetermined angle.

[0036] Preferably, referring to the overall schematic diagram of the clamp jaw device shown in Figure 1 and the schematic side cross-sectional diagram of the inside of the casing shown in Figure 5, the housing 10 includes at least one opening 11, and the article is housed inside the housing 10 through the opening 11. The clamp jaw device further includes at least one shielding mechanism 90, which is installed on the outer wall of the casing 80, and when the projection structure 200 and the recess structure 1010 engage and come into contact, the shielding mechanism 90 moves into the opening 11 and contacts the end face of the housing 10 having the opening 11, preventing the article from falling out of the housing 10 through the opening 11. When the clamp jaw device grips the housing 10, there is an opening 11 in the housing 10. If the housing 10 is affected by an external force, vibration and shaking will occur, which can cause items inside the housing 10 to fall out through the opening 11. The shielding mechanism 90 shields the opening side of the housing 10 and makes close contact with the housing 10 structure, thereby preventing items from falling out through the opening 11 and ensuring the safety of items stored inside the housing 10.

[0037] Preferably, the shielding mechanism 90 includes a movable rod member 91, a shielding member 92, and a movable connecting member 93. One end of the movable rod member 91 is connected to the casing 80, and the other end is connected to the shielding member 92 by the movable connecting member 93. The movable connecting member 93 is used to mitigate the reaction force from the housing 10 to the shielding member 92 when the shielding member 92 makes contact. When the shape of the housing 10 matches a predetermined shape, the shielding member 92 is in contact with the end face of the housing 10 having the opening 11, and the movable connecting member 93 is in its natural state, maintaining a first predetermined angle between the movable rod member 91 and the shielding member 92. When the shape of the housing 10 does not match a predetermined shape, the shielding member 92 is in contact with the end face of the housing 10 having the opening 11, and the movable connecting member 93 is in an extended state, maintaining a second predetermined angle between the movable rod member 91 and the shielding member 92. Of these, the second predetermined angle is greater than the first predetermined angle. Among these, different types of housings 10 have different sizes. For housings 10 that are relatively small in size and conform to a predetermined shape, the shielding member 92 can just abut against the end face of the housing 10 having the opening 11 when it moves into the opening 11. For housings 10 that are relatively large in size and do not conform to a predetermined shape, when the shielding member 92 moves into the opening 11, it is pushed outwards against the end face of the housing 10 having the opening 11, and the movable connecting member 93 is in an expanded state. This reduces the reaction force from the housing 10 to the shielding member 92 when it abuts against it, avoiding damage to the shielding member 92, and also enables application to various types of housings 10, thereby enhancing the adaptability and practicality of the clamp jaw device.

[0038] In one embodiment of the present invention, the second sensor mechanism detects that the relative position between the clamp jaw unit 20 and the housing 10 conforms to a predetermined standard. The main controller controls the clamp jaw unit 20 to move toward the lifting member 101 of the housing 10, and engages the projection structure 200 and the recess structure 1010 to form the engagement structure 30. At the same time, the baffle plate below the clamp jaw unit 20 blocks the optical signal path of the first sensor mechanism, and the main controller controls the stopping of the drive mechanism 60 and controls the shielding mechanism 90 to move toward the opening 11 of the housing 10, bringing the shielding mechanism 90 into contact with the end face structure having the opening 11 of the housing 10.
