Description

Technical Field

[0001] The utility model relates to the technical field of handling equipment, in particular to a crane jaw structure. Background Art

[0002] Since semiconductor components such as wafers, chips, photomasks or glass substrates are almost all fragile sheet-like objects, they must be stable during transportation to avoid being broken or damaged due to large shaking or collision. Therefore, special transportation devices such as handling carts and cranes are usually required. Especially for integrated circuit chips (ICs), they are usually placed in arrays in a carrier tray, and then several carrier trays are placed in a loading box such as a tray cassette or a magazine before moving within the factory area. For the handling of crane jaws, higher clamping and positioning actions and higher stability during movement are required.

[0003] However, when the above crane jaws are in use, the following problems and deficiencies need to be improved:

[0004] First, the positioning of the jaws generally relies on a large number of sensors. At least one transmitter and one receiver are respectively provided on the jaws and the loading box, and at most three groups are installed to complete the surface correspondence to further improve the accuracy. However, the more sensors, the higher the cost.

[0005] Second, the clamping action of the jaws generally uses the handle on the top of the loading box for fixation. However, the handle is located in the center of the top of the loading box, and it is easy to shake during the movement of the jaws or the crane, and not all loading boxes have handles for clamping.

[0006] Third, there are various types of loading boxes. Generally, one type of jaw corresponds to one type of loading box, or more sensors are configured to identify the type of loading box. And for the user management and control requirements, it is a necessary process to confirm the type of the loaded loading box. Therefore, it often requires a relatively high cost to configure multiple jaws or sensors.

[0007] Fourth, since the carrier tray is only placed on the track in the magazine, it is easy to protrude out of the magazine due to shaking or improper manual placement, resulting in the exposure of the carrier tray and even collision with the jaws or other components.

[0008] Therefore, the above problems need to be solved urgently. Summary of the Utility Model

[0009] The purpose of the utility model is to provide a crane jaw structure, which can complete the clamping and positioning actions and the magazine identification actions by using a simple structure and a small number of sensors, so as to achieve stable clamping, magazine identification and convenient management and control;

[0010] Another object of the present utility model is to provide a crane jaw structure to avoid clamping in the protruding state of the carrier plate and improve the safety of the clamping action.

[0011] To achieve this purpose, the present utility model adopts the following technical solutions:

[0012] A crane jaw structure includes:

[0013] A moving carrier;

[0014] Two transverse jaws, movably arranged on both sides below the moving carrier and capable of moving towards each other to clamp at least one cartridge, and any one of the transverse jaws includes a clamping wall, two limiting walls formed on both side edges of the clamping wall, and a support member arranged at the lower edge of the clamping wall;

[0015] A plurality of upper positioning members, movably arranged below the moving carrier and correspondingly combined with a plurality of upper protruding portions arranged on the top surface of the cartridge;

[0016] A plurality of identification detection parts, arranged on the upper positioning members and respectively penetrating into the moving carrier with different lengths;

[0017] A plurality of identification sensing components, arranged on the moving carrier and respectively arranged on one side of each of the identification detection parts, and cooperating with the identification detection parts to identify the cartridge;

[0018] A plurality of lower positioning members, arranged on the support member and correspondingly combined with a plurality of lower protruding portions arranged on the bottom surface of the cartridge;

[0019] A plurality of clamping detection parts, respectively arranged on each of the transverse jaws;

[0020] A plurality of clamping sensing components, arranged on the moving carrier and located on one side of the clamping detection parts, and cooperating with the clamping detection parts to confirm the positions of the transverse jaws;

[0021] A plurality of protruding sensing components, arranged on the moving carrier and located on both sides of the cartridge adjacent to the clamping wall to detect the carrier plate of the cartridge.

[0022] Preferably, the upper positioning member has a suspension assembly fixedly arranged on the bottom surface of the moving carrier, a lifting assembly movably arranged on the suspension assembly, an elastic assembly arranged on the suspension assembly and pushing the lifting assembly, and a plurality of abutting parts arranged on the lifting assembly.

[0023] Preferably, each end of the abutting part is respectively provided with a guiding part.

[0024] Preferably, a hook portion is provided at the bottom end of the suspension assembly, and a limiting portion is provided on the top surface of the lifting assembly so that the lifting assembly is coupled to the suspension assembly.

[0025] Preferably, an identification code is provided on the top surface of the cartridge, and a plurality of readers for reading the identification code are provided on the moving carrier.

[0026] Preferably, a height adjustment portion is provided on each of the identification detection portions.

[0027] Preferably, a second positioning member is provided on one side of the upper positioning member, and a plurality of connecting members are provided between the upper positioning member and the second positioning member so that the upper positioning member and the second positioning member act synchronously.

[0028] Preferably, a clamping groove is provided on at least one side of the support member to correspondingly engage with the lower protruding portion.

[0029] Preferably, a fixing plate for coupling with the moving carrier is provided on the transverse clamping jaw, and a perforation portion corresponding to the protruding sensing assembly is provided on the fixing plate.

[0030] Preferably, a plurality of buffer members are provided on the transverse clamping jaw on the clamping wall, the limiting wall and the support member.

[0031] Advantages of the present utility model:

[0032] In the present utility model, a crane clamping jaw structure is proposed. When the user performs a clamping action on the cartridge, first move the crane approximately above the cartridge, and gradually lower the moving carrier so that the upper positioning member corresponds to and engages with the upper protruding portion on the top surface of the cartridge to perform the first-stage positioning. At the same time, in order to identify different types of cartridges, the penetration amplitude of the identification detection portion into the moving carrier is different and forms a height difference. According to the different types of cartridges, the upper positioning member will be pushed up by a different height, and this height difference can be used by the identification sensing assembly to determine the type of the cartridge in real time to feed back the clamping target, which is beneficial for the user to control. Before the transverse clamping jaw moves, the protruding sensing assembly is used to confirm the placement status of all the carrier trays in the cartridge. If the carrier tray is not properly placed and protrudes outside the carrier tray, the protruding sensing assembly will send a warning signal to inform the user and at the same time pause the movement of the transverse clamping jaw to improve the safety of the clamping action. Then, the transverse clamping jaw is used to move towards each other to clamp the cartridge, and at the same time, the clamping wall, the limiting wall and the support member are used for wrap-around clamping to clamp more stably and be applicable to the clamping of various cartridges. During clamping, the lower positioning member is used for the second-stage positioning to improve the accuracy of the clamping action, and then the clamping detection portion is used to confirm the clamping state and issue a warning in a timely manner to improve the clamping stability.

[0059] Please refer to the first to fourth figures, which are the perspective view and the usage state view of the preferred embodiment of the present utility model. It can be clearly seen from the figures that the present utility model includes a mobile carrier 1, two transverse clamping jaws 2, several upper positioning members 3, multiple identification and detection parts 31, several lower positioning members 231, multiple clamping detection parts 24, multiple clamping sensing components 12, and multiple protruding sensing components 13.

Several lower positioning members 231 are arranged on the support member 23 and are correspondingly combined with lower protruding parts 52 arranged on the bottom surface of the material box 5. Multiple clamping detection parts 24 are respectively arranged on each transverse clamping jaw 2. Multiple clamping sensing components 12 are arranged on the mobile carrier 1 and are located on one side of the clamping detection parts 24, and cooperate with the clamping detection parts 24 to confirm the positions of the transverse clamping jaws 2. Multiple protruding sensing components 13 are arranged on the mobile carrier 1 and are located on both sides of the material box 5 adjacent to the clamping wall 21 to detect the placement condition of the carrier plate 53 of the material box 5.

[0060] Preferably, the transverse clamping jaw 2 has a fixing plate 25 for combining with the mobile carrier 1, and the fixing plate 25 has a perforation part 251 corresponding to the protruding sensing component 13 in position.

[0061] Preferably, the upper positioning member 3 has a suspension assembly 32 fixed to the bottom surface of the mobile carrier 1, a lifting assembly 33 movably arranged on the suspension assembly 32, an elastic assembly 34 arranged on the suspension assembly 32 and pushing against the lifting assembly 33, and multiple abutting parts 35 arranged on the lifting assembly 33. When the abutting parts 35 are combined with the upper protruding parts 51 of different material boxes 5, the identification and detection parts 31 rise to different degrees according to the type of the material box 5.

[0062] Preferably, a hook portion 321 is provided at the bottom end of the suspension assembly 32, and a limiting portion 331 is provided on the top surface of the lifting assembly 33 for the lifting assembly 33 to be coupled to the suspension assembly 32.

[0063] The mobile carrier 1 is coupled to the overhead crane 6 and has a motor 14 for controlling the lateral movement of the crosswise gripper 2; the two crosswise grippers 2 perform linear movements in opposite directions by means of a connecting rod 26 and a guide rail 27; the clamping wall 21 of the crosswise gripper 2 abuts against the front and rear sides of the magazine 5, the limiting wall 22 limits the left and right sides of the magazine 5, and the support member 23 supports the bottom surface of the magazine 5; the lifting assembly 33 and the abutting portion 35 of the upper positioning member 3 form an F-shaped or E-shaped structure, the lifting assembly 33 is movable between the hook portion 321 and the sleeve portion 341 on the suspension assembly 32, the elastic assembly 34 is a compression spring, and the groove 351 on one side of the abutting portion 35 is for engaging with the upper protruding portion 51 of the magazine 5; the lower positioning member 231 can be a part of the support member 23 or a structure protruding from the support member 23 to be inserted between the lower protruding portions 52; the identification sensing assembly 11, the clamping sensing assembly 12, and the protruding sensing assembly 13 are break-type infrared sensors; the identification detection portion 31 and the clamping detection portion 24 are sheet structures for blocking the light of the identification sensing assembly 11 and the clamping sensing assembly 12. The corresponding forms of the above components are only examples of the preferred embodiments. Those having the same functions are within the scope of the present invention and are not limited to the above examples.

[0064] Through the above description, the structure of the present technology can be understood. Based on the corresponding cooperation of this structure, it further achieves the clamping of the magazine 5, provides a dual positioning effect, and has advantages such as high clamping stability and identification of different types of magazines 5. The detailed explanation will be described below.

[0065] Please also refer to the three-dimensional perspective view to the clamping schematic diagram (II) of the preferred embodiment of the present invention shown in FIGS. 1 to 9. When the above components are assembled, it can be clearly seen that when the user uses the present invention to clamp the magazine 5, first, the overhead crane 6 is roughly moved above the magazine 5. Since the magazines 5 to be clamped are all in fixed positions, the stop position of the overhead crane 6 can be controlled by the motor stroke of the overhead crane 6 and can be roughly stopped above the magazine 5. Then, the mobile carrier 1 gradually descends away from the overhead crane 6 by using its motor, so that the upper positioning member 3 is correspondingly combined with the upper protruding portion 51 on the top surface of the magazine 5. At this time, the abutting portion 35 abuts against the top surface of the magazine 5, and the upper protruding portion 51 is inserted into the groove 351 on one side of the abutting portion 35, and the sleeve portion 341 is pushed by the downward pushing force of the elastic assembly 34, thereby pressing the lifting assembly 33 and the abutting portion 35 to achieve the positioning effect, and the combination with the upper protruding portion 51 of the magazine 5 completes the first stage of positioning.

[0066] As shown in the second, fifth and sixth figures, the upper positioning member 3 is combined with the movable carrier 1 in such a way that the lifting member 33 can be slid up and down on the suspension member 32, wherein the top of the suspension member 32 is fixed to the bottom surface of the movable carrier 1, and the bottom is provided with a hook 321, which is a structure that can be used to hang items. This embodiment takes a disc with a diameter larger than the suspension member 32 as an example, and the suspension member 32 and the hook 321 are combined into one or integrally formed as an example, and the lifting member 33 is passed through the suspension member 32 for sliding up and down along the axial direction of the suspension member 32, and is hung on the hook 321 by using the limiting portion 331 on the top surface of the lifting member 33 to serve as the lower limit of the lowest position of the lifting member 33. In other words, depending on the type of material box 5, when the resistance part 35 is combined with the upper protrusion 51 of different material boxes 5, the upper positioning member 3 will be pushed upward to a different height, causing the lifting component 33 to move upward. The difference in the displacement length is combined with the different amplitudes of the identification detection part 31 passing through the mobile carrier 1, allowing the identification detection part 31 to rise to different degrees with the lifting component 33, and then using the identification sensing component 11 to detect the total number of identification detection parts 31 to determine the type of material box 5, so as to provide real-time feedback on the type of clamped target, which is beneficial to user control.

[0067] As shown in the third and seventh figures, before the transverse moving clamp 2 moves, the protrusion sensing component 13 on the mobile carrier 1 is first used to detect the placement status of all the supporting plates 53 in the material box 5. Specifically, the protrusion sensing component 13 is irradiated downward from the bottom of the mobile carrier 1, and its irradiation position is the front and rear sides of the material box 5, that is, the inlet and outlet sides of its supporting plates 53. In this embodiment, the position of the protrusion sensing component 13 is located above the transverse moving clamp 2, so a perforated portion 251 is designed on the fixed plate 25 of the transverse moving clamp 2, so that the light of the protrusion sensing component 13 can pass through the transverse moving clamp 2 and irradiate downward. The fixed plate 25 is used by the transverse moving clamp 2 to connect the connecting rod 26 and the guide rail 27, and the perforated portion 251 is at least in the form of a long hole, so that the transverse moving clamp 2 will not cover the protrusion sensing component 13 for a long time within its moving range. In order to reduce the weight of the fixed plate 25, this embodiment opens a larger triangular hole. Therefore, when the carrier plate 53 is not properly placed and protrudes out of the material box 5, the light of the protrusion sensing component 13 will be blocked (the figure shows that the light is blocked by one of the carrier plates 53), and a warning signal will be sent to inform the user. At the same time, the movement of the transverse clamping jaw 2 will be suspended to prevent the transverse clamping jaw 2 from hitting the carrier plate 53, thereby improving the safety of the clamping action.

[0068] As shown in the third, eighth, and ninth figures, next, the transverse clamping jaws 2 are used to clamp the magazine 5 by moving towards each other, and at the same time, the clamping wall 21, the limiting wall 22, and the support member 23 are used for wrapped clamping. Specifically, the clamping wall 21 is used to abut against the front and rear sides of the magazine 5 on a large area. The front and rear sides refer to the inlet and outlet sides of the carrier plate 53 on the magazine 5. Therefore, the clamping wall 21 can prevent the carrier plate 53 from sliding out of the magazine 5 at the same time. The limiting wall 22 is a sheet body bent from both sides of the clamping wall 21 to limit the left and right sides of the magazine 5. The support member 23 is a sheet body bent from the lower edge of the clamping wall 21 to support the bottom surface of the magazine 5. Thus, the clamping action of the transverse clamping jaws 2 is to tightly abut against the front and rear sides, support the bottom surface upward, and supplement with the limitation of the left and right sides, so that the magazine 5 can be clamped more stably. During clamping, the lower positioning member 231 is used for the second-stage positioning. The lower positioning member 231 can be positioned by being inserted between the lower protruding portions 52 of the magazine 5. Therefore, combined with the upper positioning member 3, a double positioning effect can be provided to improve the accuracy of the clamping action. Then, the clamping detection unit 24 and the clamping sensing component 12 are used to confirm the clamping state. Specifically, the clamping sensing component 12 includes a starting point positioning function (such as the clamping sensing component 12a) and a positioning function for multiple correct clamping positions (such as the clamping sensing components 12b, 12c), so that the clamping detection unit 24 can only be detected by the clamping sensing component 12 when the lower positioning member 231 is completely combined with the magazine 5. Thereby, it is judged whether the transverse clamping jaws 2 have indeed clamped the magazine 5. On the contrary, if the clamping sensing component 12 does not detect the clamping detection unit 24, a warning will be issued. In this way, the magazine 5 can be clamped firmly.

[0069] And since the transverse clamping jaws 2 of this case are mainly for the magazine 5 (Magazine) for loading the IC carrier plate 53, although there are multiple types of magazines 5, the differences between them are only in height or width (the positions of the upper protruding portions 51 are different). And the clamping method of this case does not limit the height of the magazine 5, but can be applicable to the clamping of multiple types of magazines 5.

[0070] Please refer to FIGS. 10 to 13 simultaneously, which are the schematic diagram of the positioning structure to the identification schematic diagram (2) of another preferred embodiment of the present invention. It can be clearly seen from the figures that this embodiment is similar to the above embodiment with minor differences. Only the number of the upper positioning members 3 is changed to two, and the two upper positioning members 3 are arranged on the same straight line perpendicular to the moving direction of the transverse gripper 2. Therefore, as long as the two cartridges 5 are arranged side by side and the front and rear sides of the two cartridges 5 are flush, so as to be simultaneously abutted against the clamping wall 21, the transverse gripper 2 can clamp the two cartridges 5 at the same time. In order to make the positioning action of the upper positioning member 3 and the lower positioning member 231 easier, a guiding portion 352 is respectively provided at the end of each abutting portion 35, and a clamping groove 232 is provided on at least one side of the support member 23 to correspondingly engage with the lower protruding portion 52. The guiding portion 352 is an inclined angle or a rounded corner for abutting, which can assist the upper protruding portion 51 to enter the groove 351 on one side of the abutting portion 35 when the position of the transverse gripper 2 is offset, and the clamping groove 232 can cooperate with the lower positioning member 231 to perform a clamping action on the lower protruding portion 52, further improving the overall positioning effect. In addition, a plurality of buffer members 28 are provided on the transverse gripper 2 on the clamping wall 21, the limiting wall 22 and the support member 23. The buffer members 28 are made of rubber, silica gel, or other soft plastic materials and are arranged at the positions on the transverse gripper 2 that will contact the cartridge 5. In addition to avoiding collision damage, the buffer members 28 can also reduce the vibration generated when the transverse gripper 2 contacts the cartridge 5 by absorbing the impact force.

[0071] As shown in FIG. 11, or a recognition code 54 may be provided on the top surface of the cartridge 5 at the same time, and at least one reader 15 for reading the recognition code 54 is provided on the moving carrier 1. When the transverse gripper 2 clamps the cartridge 5, the information of the recognition code 54 can be linked with the reader 15 at the same time to obtain the information related to the cartridge 5 stored in the recognition code 54, which is more beneficial for the user to manage and control.

[0072] In addition, as shown in FIGS. 12 and 13, in this embodiment, another type of cartridge 5 is clamped. Since the width and height of this cartridge 5 are different, the different width makes the corresponding abutting portion 35 of the upper protruding portion 51 and the actual abutting groove 351 also different, and the height is relatively high, so that the upper positioning member 3 is pushed higher, and the two identification detection portions 31 are successively detected by the identification sensing component 11, so that the user can know the type of the current cartridge 5 through the feedback signals of the two identification sensing components 11.

[0073] Please refer to FIGS. 14 and 15 simultaneously, which are the structural schematic diagram and adjustment schematic diagram of the upper positioning member 3 of another preferred embodiment of the present utility model. It can be clearly seen from the figures that this embodiment is similar to the above embodiment with minor differences. Only one side of the upper positioning member 3 has a second positioning member 4, and at least one connecting member 41 is provided between the upper positioning member 3 and the second positioning member 4 to enable the upper positioning member 3 and the second positioning member 4 to act synchronously. The number of upper positioning members 3 is also two, so the number of second positioning members 4 is also two. Since the upper positioning member 3 and the second positioning member 4 are fixedly arranged side by side through the connecting member 41, they will simultaneously contact the same material box during use, forming a situation of multi-point contact, which can prevent errors caused by the shaking or tilting of the clamping jaws. Two connecting members 41 are provided between each group of upper positioning members 3 and second positioning members 4 in this embodiment.

[0074] In addition, a height adjustment portion 311 is provided on the identification and detection portion 31, which can be used to adjust the height of the identification and detection portion 31 relative to the upper positioning member 3, that is, the length of the identification and detection portion 31 penetrating into the moving carrier 1. In this embodiment, the adjustment is carried out by the design of screws cooperating with long holes. Thereby, by adjusting the movement range of the lifting assembly 33 and the height of the identification and detection portion 31, the upper positioning member 3 (and the second positioning member 4) can be freely adjusted to correspond to different types of material boxes, and more types of material boxes can be applied. Moreover, the upper positioning member 3 of the same design can be used to achieve this function, without designing different upper positioning members 3 for the distance between the hook portion 321 and the sleeve portion 341 or the height of the identification and detection portion 31, enabling the upper positioning member 3 to be modularly manufactured and reducing the manufacturing cost.

[0075] In summary, the key points of the overhead crane clamping jaw structure proposed by the present utility model are as follows:

[0076] First, by using the design of the upper positioning member 3 and the lower positioning member 231, a dual positioning effect is provided to improve the accuracy of the clamping action, while saving the cost of the positioning sensor.

[0077] Second, by using the design of the identification and detection portion 31 and the identification and sensing assembly 11, the type of the material box 5 can be judged by a small number of sensors, and the type of the clamping target can be fed back in real time, which is beneficial for the user to control.

[0078] Third, by using the design of the suspension assembly 32, the lifting assembly 33, the abutting portion 35, the hook portion 321 and the limiting portion 331, the identification action of the type of the material box 5 can be completed by simple physical actions, reducing the purchase cost of electronic devices.

[0079] Fourth, by using the design of the guiding portion 352 or the clamping groove 232, the positioning effect of the upper positioning member 3 or the lower positioning member 231 is improved respectively.

[0080] Fifth, by means of the design of the second positioning member 4 and the connecting member 41, the upper positioning member 3 can be more stably combined with the upper protruding portion 51 of the material box 5, preventing errors caused by the shaking or tilting of the clamping jaws.

[0081] Sixth, by means of the design of the height adjustment portion 311, the upper positioning member 3 can be applied to material boxes 5 with a wider range and more different heights, and due to the free adjustment, the upper positioning member 3 can be modularly designed, thereby reducing the manufacturing cost.

[0082] Seventh, by means of the design of the protruding sensing assembly 13, the placement status of all the carrier plates 53 in the material box 5 is detected, so as to send a warning signal to inform the user in case of an abnormality, and at the same time, the movement of the transverse clamping jaw 2 is paused to avoid the transverse clamping jaw 2 hitting the carrier plate 53, thereby improving the safety of the clamping action.
