Description

Technical Field

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

[0002] Since semiconductor components such as wafers, chips, photomasks or glass substrates are almost all sheet-shaped and fragile items, they must be stable during transportation to avoid being broken or damaged due to large shaking or collision. Therefore, special transportation devices such as cantilever cranes and overhead cranes are usually required. Especially for integrated circuit chips (ICs), they are usually placed in an array on a carrier tray, and then several carrier trays are placed in a loading box such as a tray cassette or a magazine, and then transported within the factory area. Therefore, for overhead crane handling, higher positioning accuracy requirements and smooth movement requirements are put forward for the jaws of the overhead crane.

[0003] The jaws of the existing overhead cranes have the following deficiencies:

[0004] First, the positioning of the jaws generally relies on a large number of sensors. At least there is a transmitter and a receiver on the jaw and the loading box respectively, and at most three groups are installed to complete the planar positioning 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 usually set in the center of the top of the loading box, so that the loading box is prone to shaking during the movement of the overhead crane. In addition, not all loading boxes are provided with handles that can be clamped.

[0006] Third, there are many types of loading boxes. Usually, one type of jaw corresponds to one type of loading box, or more sensors are configured to identify the type of loading box. And it is a necessary process to confirm the type of the clamped loading box. Therefore, it often requires a high cost to configure multiple jaws or sensors.

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

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

[0058] Embodiment 1

[0059] Figures 1 to 4 For the three-dimensional perspective view to the use state diagram of the embodiment of the present utility model, it can be clearly seen from the figure that the present utility model includes:

[0060] A mobile carrier 1;

[0061] Two transverse grippers 2, movably arranged below the mobile carrier 1, and capable of moving towards each other to clamp at least one magazine 5, and each transverse gripper 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;

[0062] At least one upper positioning member 3, movably arranged below the mobile carrier 1, and correspondingly engaged with at least one upper protruding portion 51 on the top surface of the magazine 5;

[0063] A plurality of identification detection parts 31, all arranged on the upper positioning member 3;

[0064] A plurality of identification sensing elements 11, all arranged on the mobile carrier 1 and on one side close to the plurality of identification detection parts 31, and the plurality of identification detection parts 31 cooperate with the plurality of identification sensing elements 11 to identify the type of the magazine 5;

[0065] At least one lower positioning member 231, arranged on the support member 23, and correspondingly engaged with at least one lower protruding portion 52 on the bottom surface of the magazine 5;

[0066] A plurality of clamping detection parts 24, respectively arranged on each transverse gripper 2; and

[0067] A plurality of clamping sensing elements 12 are all arranged on the moving carrier 1 and correspond one by one to a plurality of clamping detection parts 24. Each clamping sensing element 12 cooperates with its corresponding clamping detection part 24 to confirm the positions of the transverse clamping jaws 2.

[0068] Preferably, the upper positioning member 3 includes a suspension element 32 fixedly arranged on the bottom surface of the moving carrier 1, a lifting element 33 movably arranged on the suspension element 32, an elastic element 34 arranged on the suspension element 32 and pushing against the lifting element 33, and a plurality of abutting parts 35 arranged on the lifting element 33. When the plurality of abutting parts 35 abut against the upper protruding parts 51 of different cartridges 5, the plurality of identification detection parts 31 rise to different degrees according to the types of the cartridges 5.

[0069] Preferably, a hook part 321 is arranged at the bottom end of the suspension element 32, and a limiting part 331 is arranged on the top surface of the lifting element 33. The hook part 321 and the limiting part 331 can be adaptively engaged so that the lifting element 33 can be connected to the suspension element 32.

[0070] The moving carrier 1 is connected to a crane 6 and includes a motor 13 for controlling the movement of the transverse clamping jaws 2; the two transverse clamping jaws 2 perform linear movements in opposite directions by means of a connecting rod 25 and a guide rail 26; the clamping walls 21 of the transverse clamping jaws 2 are for abutting against the front and rear sides of the cartridge 5, the limiting walls 22 are for limiting the left and right sides of the cartridge 5, and the support member 23 is for supporting the bottom surface of the cartridge 5; the lifting element 33 and the abutting part 35 of the upper positioning member 3 form an F-shaped or E-shaped structure. The lifting element 33 is movably arranged between a hook part 321 on the suspension element 32 and a sleeve part 341. The elastic element 34 is a compression spring. A groove 351 on one side of the abutting part 35 is for engaging with the upper protruding part 51 of the cartridge 5; the lower positioning member 231 can be a part of the support member 23 or a structure protruding from the support member 23 for being inserted between the lower protruding parts 52; the identification sensing element 11 and the clamping sensing element 12 are interruption type infrared sensors; the identification detection part 31 and the clamping detection part 24 are sheet structures for interrupting the light of the identification sensing element 11 and the clamping sensing element 12. The corresponding models of the above elements are only examples of the embodiments. Any models with the same functions belong to the scope of the present utility model and are not limited to the above examples.

[0071] Through the above description, the structure of the present technology can be understood. Based on the corresponding cooperation of this structure, the clamping of the cartridge 5 (Magazine) is achieved, and a double positioning effect is provided. Moreover, it has advantages such as high clamping stability and identification of the types of the cartridges 5. For a detailed description, please refer to the following text.

[0072] Please also refer to Figures 1 to 8 as shown in Figure 8The three-dimensional perspective view of the first embodiment of the present invention and the clamping schematic diagram (second) are clearly shown in the figure. Through the above-mentioned component assembly, it can be clearly seen that when the user uses the present invention to clamp the material box 5, the crown crane 6 is first moved roughly to the top of the material box 5. Since the material box 5 to be clamped is in a fixed position, the stopping position of the crown crane 6 can be controlled by the stroke of the motor 13 of the crown crane 6, and it can roughly stop above the material box 5. Then the mobile carrier 1 uses its motor 13 to gradually move away from the crown crane 6 and descend, so that the upper positioning member 3 is correspondingly engaged with the upper protrusion 51 on the top surface of the material box 5. At this time, the resistance portion 35 is against the top surface of the material box 5, and the upper protrusion 51 is inserted into the groove 351 on one side of the resistance portion 35, and the sleeve portion 341 is pushed downward by the force of the elastic element 34, thereby pressurizing the lifting element 33 and the resistance portion 35 to achieve the positioning effect, and then abut with the upper protrusion 51 of the material box 5 to complete the first stage of positioning.

[0073] like Figure 2 、 Figure 5 and Figure 6 As shown, since the upper positioning member 3 is connected to the mobile carrier 1 in a manner that the lifting element 33 is slidably arranged on the suspension element 32, wherein the top of the suspension element 32 is fixed to the bottom surface of the mobile carrier 1, and the bottom is provided with a hook 321, which is a structure that can be used to hang objects. This embodiment takes a disc with a diameter larger than the suspension element 32 as an example, and a structure in which the suspension element 32 and the hook 321 are connected as one or integrally formed as an example, and the lifting element 33 is penetrated by the suspension element 32 for sliding up and down along the axial direction of the suspension element 32, and is hung on the hook 321 by using the limiting portion 331 on the top surface of the lifting element 33 to serve as the lower limit of the lowest position of the lifting element 33. In other words, depending on the type of material box 5, when the resistance part 35 abuts against 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 element 33 to move upward. The difference in the displacement length is different in accordance with the amplitude of the identification detection part 31 passing through the mobile carrier 1, so that the identification detection part 31 can rise to different degrees with the lifting element 33, and then the type of the material box 5 is determined by the total number of identification detection parts 31 detected by multiple identification sensing elements 11, so as to provide real-time feedback on the type of the clamped target, which is beneficial to user control.

[0074] like Figure 3 、 Figure 7 and Figure 8As shown, the horizontal transfer gripper 2 then moves towards each other to grip the magazine 5, and at the same time, it performs a wrapping grip with the clamping wall 21, the limiting wall 22, and the support member 23. Specifically, the clamping wall 21 can abut against the front and rear sides of the magazine 5 over a large area. The front and rear sides refer to the inlet and outlet sides of the carrier tray 53 on the magazine 5. Therefore, the clamping wall 21 can also prevent the carrier tray 53 from sliding out of the magazine 5. 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. Therefore, the clamping action of the horizontal transfer gripper 2 tightly abuts against the front and rear sides, supports the bottom surface upward, and is supplemented by the limitation of the left and right sides, so that the magazine 5 can be gripped 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 into the lower protruding portion 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 element 12 are used to confirm the clamping state. Specifically, the clamping sensing element 12 includes a starting point positioning function (such as the clamping sensing element 12a) and the positioning functions of multiple correct clamping positions (such as the clamping sensing elements 12b and 12c), so that the clamping detection unit 24 can only be detected by the clamping sensing element 12 when the lower positioning member 231 is completely engaged 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 clamping sensing element 12 does not detect the clamping detection unit 24, a warning will be issued, and thus the magazine 5 can be indeed gripped.

[0075] And since the horizontal transfer gripper 2 in this case is mainly for the magazine 55 (Magazine) for loading the IC carrier tray 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). The clamping method in this case does not limit the height of the magazine 5 and can be applicable to the clamping of multiple types of magazines 5.

[0076] Embodiment 2

[0077] Please refer to Figures 9 to 12As shown, the difference between this embodiment and the above embodiment is that 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 material boxes 5 are arranged side by side and the front and rear sides of the two material boxes 5 are flush, so as to be simultaneously abutted against the clamping wall 21, so that the transverse gripper 2 can simultaneously grip the two material boxes 5. Also, in order to make it easier for the upper positioning member 3 and the lower positioning member 231 to perform the positioning action, 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, which corresponds to and engages with the lower protruding portion 52. The guiding portion 352 is an oblique angle or a rounded corner on the abutting portion 35. When the position of the transverse gripper 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.

[0078] As Figure 10 shown, a recognition code 54 is provided on the top surface of the material box 5, and at least one reader 14 for reading the recognition code 54 is provided on the moving carrier 1, so that when the transverse gripper 2 grips the material box 5, the information of the reader 14 is used to link the recognition code 54 at the same time, so as to know the information related to the material box 5 stored in the recognition code 54, which is more beneficial for the user to control.

[0079] In addition, as Figure 11 and Figure 12 shown, this embodiment grips 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 height part is higher, so that the upper positioning member 3 is pushed higher, and the two identification detection portions 31 are successively detected by the identification sensing element 11, so as to let the user know the type of the current material box 5 through the feedback signals of the two identification sensing elements 11.

[0080] Embodiment Three

[0081] Please also refer to Figure 13 and Figure 14 shown, the difference between this embodiment and the above embodiment is that only a second positioning member 4 is provided on one side of the upper positioning member 3, and at least one connecting member 41 is provided between the upper positioning member 3 and the second positioning member 4, so that the upper positioning member 3 and the second positioning member 4 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 abut against the same material box 5 during use, forming a situation of multi-point contact, and the error caused by the shaking or tilting of the gripper can be prevented. Two connecting members 41 are provided between each group of the upper positioning member 3 and the second positioning member 4 in this embodiment.

[0082] In addition, a height adjustment portion 311 is provided on the identification and detection portion 31 for adjusting 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 11. In this embodiment, the adjustment is performed by screws cooperating with slotted holes. Therefore, by coordinating the adjustment of the movement range of the lifting element 33 and the height adjustment 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 cartridges 5, enabling the application of more types of cartridges 5, and this function can be achieved with the upper positioning member 3 of the same design. There is no need to design 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, allowing the upper positioning member 3 to be modularly manufactured and reducing the manufacturing cost.

[0083] The above is only the preferred embodiment of the present invention and does not limit the patent scope of the present invention. Therefore, all simple modifications and equivalent structural changes made by using the content of the specification and drawings of the present invention should be equally included in the patent scope of the present invention, and this is hereby stated.

[0084] Therefore, the beneficial effects of the gripper of the overhead crane of the present invention are as follows:

[0085] 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, while saving the cost of the positioning sensor.

[0086] Second, by using the design of the identification and detection portion 31 and the identification sensing element 11, the type of the cartridge 5 can be judged with 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.

[0087] Third, by using the design of the suspension element 32, the lifting element 33, the abutting portion 35, the hook portion 321 and the limiting portion 331, the identification action of the type of the cartridge 5 can be completed by simple physical actions, reducing the purchase cost of electronic devices.

[0088] 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.

[0089] Fifth, by using the design of the second positioning member 4 and the connecting member 41, the upper positioning member 3 can be more smoothly engaged with the upper protruding portion 51 of the cartridge 5, preventing errors caused by the shaking or tilting of the gripper.

[0090] Sixth, by using the design of the height adjustment portion 311, the upper positioning member 3 can be applied to a wider range and more different heights of cartridges 5, and due to the free adjustment, the upper positioning member 3 can be modularly designed, thus reducing the manufacturing cost.

[0091] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. 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 utility model. 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 utility model shall be included within the protection scope of the claims of the present utility model.
