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 sheet-like and fragile items, they must be stable during transportation to avoid being cracked or damaged due to large shaking or collision. Therefore, special transportation devices such as forklifts and cranes are usually required. Especially for integrated circuit chips (ICs), they usually need to be 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 in the factory area. In terms of the handling of the crane jaw, higher clamping and positioning actions and higher stability during movement are required.

[0003] However, when the above-mentioned crane jaw is in use, the following problems and deficiencies need to be improved:

[0004] First, the positioning of the jaw generally relies on a large number of sensors. At least one transmitter and one receiver are respectively provided on the jaw 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 jaw 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 jaw or the crane, and not all loading boxes have a handle 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 control requirements of users, it is a necessary process to confirm the type of the clamped loading box. Therefore, it often requires a high-cost configuration of multiple jaws or sensors.

[0007] Therefore, the above problems need to be solved urgently. Summary of the Utility Model

[0008] The purpose of the utility model is to provide a crane jaw structure, which can complete the clamping and positioning actions and the identification action of the magazine with a simple structure and a small number of sensors, so as to achieve stable clamping, magazine identification and convenient control;

[0009] Another purpose of the utility model is to provide a crane jaw structure. When the moving carrier approaches the magazine, the positioning column and the positioning guide are first used for calibration as a pre-operation before the lateral movement of the jaw and the magazine are positioned, so that the upper positioning member is easier to position.

[0010] To achieve this purpose, the utility model adopts the following technical solutions:

[0011] An overhead crane jaw structure, comprising:

[0012] A moving carrier;

[0013] Two transverse moving jaws, movably arranged on both sides below the moving carrier, and capable of moving towards each other to clamp a plurality of material boxes, and each of the transverse moving jaws includes a clamping wall, two limiting walls formed on both side edges of the clamping wall, and a support member formed on the lower edge of the clamping wall;

[0020] A plurality of positioning columns, arranged on the moving carrier and extending downward to one side of the transverse moving jaws;

[0021] A plurality of positioning guides, arranged on one side of the material box to be combined with the positioning columns;

[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, the ends of the abutting parts respectively have guiding parts.

[0024] Preferably, the bottom end of the suspension assembly is provided with a hook part, and the top surface of the lifting assembly has a limiting part, so that the lifting assembly is combined on the suspension assembly.

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

[0026] Preferably, each of the identification detection parts is provided with a height adjustment part.

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

[0028] Preferably, at least one side of the support part has a clamping groove for corresponding combination with the lower protruding part.

[0029] Preferably, each of the positioning guides has a conical guiding part and a limiting channel communicating with the tip of the conical guiding part.

[0030] Preferably, the moving carrier is provided with a driving device and a linkage mechanism pivotally connected to the driving device. The linkage mechanism includes a linkage plate pivotally connected to the driving device and a connecting rod member pivotally provided at both ends to the linkage plate and the transverse clamping jaw respectively. The transverse clamping jaw is arranged on a guide rail and is driven by the linkage mechanism.

[0031] Advantages of the present utility model:

[0032] For the overhead crane jaw structure proposed by the present utility model, when the user performs a clamping action on the cartridge, first move the overhead crane roughly above the cartridge and gradually lower the moving carrier. First, use the positioning posts and positioning guides for fine positioning adjustment to perform the first-stage positioning. The moving carrier continues to descend so that the upper positioning part corresponds to and combines with the upper protruding part on the top surface of the cartridge to perform the second-stage positioning. At the same time, in order to identify different types of cartridges, the penetration amplitude of the identification detection part in the moving carrier is different and forms a height difference. According to different types of cartridges, the upper positioning part will be pushed upward to different heights, and this height difference can be used for the identification sensing component to judge the type of the cartridge, so as to feedback the clamping target in real time, which is beneficial for the user to control. Then, use the transverse clamping jaws to move towards each other to clamp the cartridge, and at the same time perform a wrapped clamping on the clamping wall, limiting wall and support part, so that it can clamp more stably and is suitable for clamping various cartridges. When clamping, use the lower positioning part for the third-stage positioning to improve the accuracy of the clamping action, and then cooperate with the clamping detection part to confirm the clamping state and issue a warning in due time to improve the clamping stability.

[0057] Before explaining in detail any implementation manner of the present application, it should be understood that the present application is not limited to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0058] In the present application, the terms "comprising", "including", "having" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article or device comprising that element.

[0059] In the present application, the term "and / or" is an associative relationship describing associated objects, indicating that three relationships may exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump may represent: the sole existence of a centrifugal vortex magnetic pump, the simultaneous existence of a centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump, and the sole existence of a centrifugal vortex magnetic pump. Additionally, in the present application, the character " / " generally represents an "and / or" relationship between the associated objects before and after.

[0060] In this application, the terms "connect", "combine", "couple", and "mount" can be direct connections, combinations, couplings, or mounts, or can be indirect connections, combinations, couplings, or mounts. Among them, by way of example, a direct connection means that two parts or components are connected together without the need for an intermediate member, and an indirect connection means that two parts or components are respectively connected to at least one intermediate member, and these two parts or components are connected through the intermediate member. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and can include electrical connections or couplings.

[0061] In this application, those of ordinary skill in the art will understand that relative terms used in connection with a quantity or condition (e.g., "about", "approximately", "substantially", etc.) are intended to include the recited value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances resulting from manufacture, assembly, use, etc. associated with a particular value. Such terms should also be considered to disclose a range defined by the absolute values of two endpoints. A relative term may refer to a plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values that do not employ relative terms should also be disclosed as having tolerances. In addition, when expressing a relative angular positional relationship (e.g., substantially parallel, substantially perpendicular), "substantially" may refer to a plus or minus a certain number of degrees (e.g., 1 degree, 5 degrees, 10 degrees or more) from the indicated angle.

[0062] In this application, those of ordinary skill in the art will understand that the functions performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the functions performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0063] In this application, the orientation terms such as "upper", "lower", "left", "right", "front", "rear", etc. are described based on the orientation and positional relationship shown in the drawings, and should not be construed as a limitation on the embodiments of this application. In addition, in the context, it should also be understood that when it is mentioned that one element is connected "above" or "below" another element, it can not only be directly connected "above" or "below" another element, but also be indirectly connected "above" or "below" another element through an intermediate element. It should also be understood that orientation terms such as upper side, lower side, left side, right side, front side, rear side, etc. not only represent the positive orientation, but can also be understood as the side orientation. For example, the lower side can include directly below, lower left, lower right, lower front, and lower rear, etc.

[0064] Please refer to the perspective view to the usage state diagrams of the preferred embodiment of the present invention shown in the first to fourth figures. It can be clearly seen from the figures that the present invention includes a mobile carrier 1, two transverse clamping jaws 2, several upper positioning members 3, multiple identification sensing components 11, several lower positioning members 231, multiple clamping detection parts 24, multiple clamping sensing components 12, multiple positioning columns 13 and multiple positioning guides 6. The two transverse clamping jaws 2 are movably arranged on both sides below the mobile carrier 1 and can move towards each other to clamp several material boxes 5. Each transverse clamping jaw 2 includes a clamping wall 21, two limiting walls 22 formed on both side edges of the clamping wall 21 and a support member 23 formed on the lower edge of the clamping wall 21; several upper positioning members 3 are movably arranged below the mobile carrier 1 and are correspondingly combined with several upper protruding parts 51 arranged on the top surface of the material box 5; multiple identification detection parts 31 are arranged on the upper positioning members 3 and respectively penetrate into the mobile carrier 1 with different lengths; multiple identification sensing components 11 are arranged on the mobile carrier 1 and are respectively arranged on one side of each identification detection part 31 and cooperate with the identification detection part 31 to identify the types of the material boxes 5; several lower positioning members 231 are arranged on the support member 23 and are correspondingly combined with several 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 part 24 and cooperate with the clamping detection part 24 to confirm the positions of the transverse clamping jaws 2. Multiple positioning columns 13 are arranged on the mobile carrier 1 and extend downward to one side of the transverse clamping jaws 2; multiple positioning guides 6 are arranged on one side of the material box 5 to be combined with each positioning column 13.

[0065] Preferably, the mobile carrier 1 is provided with a driving device 14 and a linkage mechanism 15 pivotally connected to the driving device 14. The linkage mechanism 15 includes a linkage plate 151 pivotally connected to the driving device 14 and a connecting rod member 152 with two ends respectively pivotally arranged on the linkage plate 151 and the transverse clamping jaw 2. The transverse clamping jaw 2 is arranged on a guide rail 25 and is driven by the linkage mechanism 15.

[0066] Preferably, the upper positioning member 3 has a suspension assembly 32 fixedly arranged on 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 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 on different material boxes 5, the identification detection part 31 rises to different degrees according to the types of the material boxes 5.

[0067] Preferably, a hook part 321 is arranged at the bottom end of the suspension assembly 32, and a limiting part 331 is arranged on the top surface of the lifting assembly 33 to combine the lifting assembly 33 with the suspension assembly 32.

[0068] Among them, the mobile carrier 1 is coupled to a crane 7; the driving device 14 takes a motor as an example; the two transverse clamping jaws 2 perform linear movements in opposite directions by means of a linkage mechanism 15; the clamping walls 21 of the transverse clamping jaws 2 abut against the front and rear sides of the magazine 5, the limiting walls 22 limit 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 moves between the hook portion 321 and the sleeve portion 341 on the suspension assembly 32, the elastic component 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, so as to be inserted between the lower protruding portions 52; the identification sensing component 11 and the clamping sensing component 12 are interruption type infrared sensors; the identification detection portion 31 and the clamping detection portion 24 are sheet structures for interrupting the light of the identification sensing component 11 and the clamping sensing component 12; the positioning post 13 is a long rectangular structure; the positioning guide 6 is two L-shaped block structures arranged oppositely, and the inner side surface thereof is a guiding L-shaped inclined surface 61. The corresponding types of the above components are only examples of the preferred embodiments, and all structures with the same functions belong to the scope of the present invention and are not limited to the above examples.

[0069] Through the above description, the structure of the present technology can be understood. Based on the corresponding cooperation between this structure, it further achieves the clamping of the magazine 5, provides a three-resetting effect, and has advantages such as high clamping stability and identification of different types of magazines 5. The detailed explanation will be given in the following description.

[0070] Please also refer to the perspective view to the clamping schematic diagram (two) 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 pick up the magazine 5, first, the crane 7 is roughly moved above the magazine 5. Since the magazines 5 to be picked up are all located at fixed positions, the stop position of the crane 7 can be controlled by the motor stroke of the crane 7, or it can be roughly stopped above the magazine 5. Then, the mobile carrier 1 gradually descends away from the crane 7 by using its motor. During the descending process, the positioning post 13 will first contact the positioning guide 6. When the rectangular surface of the positioning post 13 abuts against the L-shaped inclined surface 61 of the positioning guide 6, since the two positioning guides 6 are arranged oppositely or in reverse directions, they respectively provide limiting and guiding effects in two directions. For example, the positioning guide 6a provides limiting on the left and rear sides, and the positioning guide 6b provides limiting on the right and front sides, thereby compensating for the error of simply controlling the stop position of the crane 7 by the motor stroke and providing the horizontal positioning function in the first stage (as shown in FIG. 5).

[0071] Next, the moving carrier 1 continues to descend, so that the upper positioning member 3 is correspondingly combined with the upper convex portion 51 on the top surface of the cartridge 5. At this time, the abutting portion 35 abuts against the top surface of the cartridge 5, and the upper convex portion 51 is inserted into the groove 351 on one side of the abutting portion 35, and a sleeve portion 341 is pushed by the downward pushing force of the elastic component 34, and then the lifting and lowering component 33 and the abutting portion 35 are pressurized to achieve the positioning effect, and then combined with the upper convex portion 51 of the cartridge 5 to complete the positioning in the second stage (as shown in the sixth figure).

[0072] As shown in the second figure and the seventh figure, since the upper positioning member 3 is combined with the moving carrier 1 in such a way that the lifting and lowering component 33 is slidably arranged on the suspension component 32. The top end of the suspension component 32 is fixed to the bottom surface of the moving carrier 1, and the bottom end is provided with a hook portion 321. The hook portion 321 is a structure that can be used to hang objects. In this embodiment, a disc shape with a diameter larger than that of the suspension component 32 is taken as an example, and the suspension component 32 and the hook portion 321 are combined or integrally formed as an example. The lifting and lowering component 33 is arranged through the suspension component 32 to slide up and down along the axial direction of the suspension component 32, and the limiting portion 331 on the top surface of the lifting and lowering component 33 is hung on the hook portion 321 as the lower limit of the lowest position of the lifting and lowering component 33. In other words, according to the different types of the cartridge 5, when the abutting portion 35 is combined with the upper convex portion 51 of different cartridges 5, the upper positioning member 3 can be pushed up to different heights, so that the lifting and lowering component 33 moves upward. The difference in the displacement length cooperates with the different amplitudes of the identification and detection portion 31 arranged in the moving carrier 1, so that the identification and detection portion 31 can rise to different degrees along with the lifting and lowering component 33. Then, the total number of the identification and detection portions 31 detected by the identification and sensing component 11 is used to judge the type of the cartridge 5, so as to feedback the type of the clamped target in real time, which is beneficial for the user to control.

[0073] As shown in the third, eighth, and ninth figures, the horizontal transfer gripper 2 is then used to grip the magazine 5 by moving towards each other, and at the same time, a wrapping grip is performed using the gripping wall 21, the limiting wall 22, and the support member 23. First, regarding the movement of the horizontal transfer gripper 2, a driving device 14 is provided in the center of the moving carrier 1 to drive the linkage plate 151 to rotate, and the linkage plate 151 uses the link member 152 to pull the horizontal transfer gripper 2. Since the horizontal transfer gripper 2 is restricted by the guide rail 25 and can only move linearly, the action of the linkage mechanism 15 on the horizontal transfer gripper 2 is only a pushing or pulling action. With the above simple mechanical structure, a single driving device 14 can make the horizontal transfer gripper 2 move towards or away from each other synchronously. Regarding the gripping action of the horizontal transfer gripper 2, the gripping wall 21 can increase the contact area between the horizontal transfer gripper and the front and rear sides of the magazine 5. The front and rear sides refer to the inlet and outlet sides of the carrier plate 53 on the magazine 5. Therefore, the gripping wall 21 can also prevent the carrier plate 53 from sliding out of the magazine 5. The limiting wall 22 is a sheet body bent from both sides of the gripping wall 21 to limit the left and right sides of the magazine 5, and the support member 23 is a sheet body bent from the lower edge of the gripping wall 21 to support the bottom surface of the magazine 5. Thus, the gripping action of the horizontal transfer gripper 2 is to tightly hold from the front and rear sides, support upward from the bottom surface, and supplement with the limitation of the left and right sides, so that the magazine 5 can be gripped more stably. During gripping, 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 protrusions 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 gripping action. Then, the gripping detection unit 24 and the gripping sensing component 12 are used to confirm the gripping state. Specifically, the gripping sensing component 12 includes a starting point positioning function (such as the gripping sensing component 12a) and the positioning functions of multiple correct gripping positions (such as the gripping sensing components 12b, 12c), so that the gripping detection unit 24 can only be detected by the gripping sensing component 12 when the lower positioning member 231 is completely combined with the magazine 5. Thereby, it is judged whether the horizontal transfer gripper 2 has indeed gripped the magazine 5. On the contrary, if the gripping sensing component 12 does not detect the gripping detection unit 24, a warning will be issued. In this way, the magazine 5 can be gripped firmly.

[0074] And since the horizontal transfer gripper 2 in this case is 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 protrusions 51 are different), and the gripping method in this case does not limit the height of the magazine 5 and can be applicable to the gripping of multiple types of magazines 5.

[0075] Please refer to FIGS. 10 to 14 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-mentioned 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 clamping jaws 2. Therefore, as long as the two material boxes 5 are arranged side by side and the front and rear sides of the two material boxes 5 are flush, they can be simultaneously abutted against the clamping wall 21, so that the transverse clamping jaws 2 can simultaneously clamp the two material boxes 5. Each positioning guide 6 has a conical guide portion 62 and a limiting channel 63 communicating with the tip of the conical guide portion 62. By means of the conical guide portion 62, the guiding range and guiding surface are increased. As long as the positioning post 13 is above the circular range of the conical guide portion 62, it can be guided to the limiting channel 63 at the central tip. And the limiting channel 63 is a long and narrow channel with a cross-sectional shape the same as that of the positioning post 13. Since only the top end of the positioning post 13 is fixed to the moving carrier 1, the limiting channel 63 is used to limit the positioning post 13 entering therein, which can prevent the positioning post 13 from tilting and affecting the positioning effect, and further reduce the requirement for the structural strength of the positioning post 13 (as shown in FIG. 11).

[0076] Moreover, in order to make the positioning actions of the upper positioning member 3 and the lower positioning member 231 easier, each end of the abutting portion 35 is respectively provided with a guiding portion 352 and a clamping groove 232 arranged on at least one side of the support member 23 to correspond and combine with the lower protruding portion 52. The guiding portion 352 is an inclined angle or a rounded corner on the abutting surface. When the position of the transverse clamping jaws 2 is offset, it can assist the upper protruding portion 51 to enter the groove 351 on one side of the abutting portion 35, 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.

[0077] As shown in FIG. 12, or a recognition code 54 can be simultaneously provided on the top surface of the material box 5, and a plurality of readers 16 for reading the recognition code 54 are provided on the moving carrier 1. When the transverse clamping jaws 2 clamp the material box 5, the information of the recognition code 54 is simultaneously linked by the readers 16 to obtain the information related to the material box 5 stored in the recognition code 54, which is more conducive to the user's control.

[0078] In addition, as shown in FIGS. 13 and 14, when clamping another type of material box 5, since the width and height of this material box 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 higher height makes the upper positioning member 3 pushed higher, so that the two identification detection portions 31 are successively detected by the identification sensing component 11, and the user can know the type of the current material box 5 through the feedback signals of the two identification sensing components 11.

[0079] Please refer to FIGS. 15 and 16 simultaneously, which are respectively the structural schematic diagram and the adjustment schematic diagram of the upper positioning member of another preferred embodiment of the present invention. It can be clearly seen from the figures that this embodiment is similar to the above-mentioned embodiment, except that there is a second positioning member 4 on one side of the upper positioning member 3, and several connecting members 41 are 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 the upper positioning members 3 is also two, so the number of the 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. In this embodiment, two connecting members 41 are provided between each group of the upper positioning member 3 and the second positioning member 4.

[0080] 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. Thus, 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 applicable. Moreover, the upper positioning member 3 with the same design can 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, so that the upper positioning member 3 can be manufactured modularly, reducing the manufacturing cost.

[0081] The above description is only a preferred embodiment of the present utility model, and thus does not limit the patent scope of the present utility model. Therefore, all simple modifications and equivalent structural changes made by using the content of the specification and drawings of the present model should be equally included in the patent scope of the present model, and are hereby stated.

[0082] In summary, the technical key points of the overhead crane clamping jaw structure proposed by the present utility model are as follows:

[0083] First, by using the design of the upper positioning member 3 and the lower positioning member 231, a double positioning effect is provided to improve the accuracy of the clamping action, and at the same time, the cost of the positioning sensor is saved.

[0084] Second, by using the design of the identification and detection portion 31 and the identification and sensing component 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.

[0085] 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.

[0086] Fourth, by means of the design of the guiding part 352 or the clamping groove 232, the positioning effects of the upper positioning part 3 or the lower positioning part 231 are improved respectively.

[0087] Fifth, by means of the design of the second positioning part 4 and the connecting part 41, the upper positioning part 3 can be more stably combined with the upper protruding part 51 of the material box 5, preventing errors caused by the shaking or tilting of the clamping jaws.

[0088] Sixth, by means of the design of the height adjusting part 311, the upper positioning part 3 can be applicable to material boxes 5 with a wider range and more different heights. Moreover, due to the free adjustment, the upper positioning part 3 can be modularly designed, thereby reducing the manufacturing cost.

[0089] Seventh, by means of the design of the positioning column 13 and the positioning guide 6, the error of simply controlling the stopping position of the overhead crane 7 by the motor stroke is compensated, and the first-stage horizontal positioning effect is provided.

[0090] Eighth, by means of the design of the conical guiding part 62 and the limiting channel 63, the guiding range and the guiding surface can be increased. At the same time, the tilting of the positioning column 13 is prevented from affecting the positioning effect, and further, the requirement for the structural strength of the positioning column 13 is reduced.

[0091] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
