[0037] Specific embodiments are given below to introduce the technical solutions of the present application in detail.
[0038] Figure 1 This is a top view of a fixing fixture shown in an exemplary embodiment of the present application. Figure 2 This is a three-dimensional diagram of a fixing fixture according to an exemplary embodiment of the present application. Figure 1 and Figure 2 The fixing fixture for replacing spare parts of a mounting device provided in this embodiment includes a base 1, a positioning groove 2 provided on the base 1 for positioning the spare part, and a fixing component 3 provided on the base 1 for fixing the spare part positioned in the positioning groove 2; wherein,
[0039] The shape of the positioning groove 2 matches the shape of the spare part to position the spare part;
[0040] The fixing assembly 3 is arranged around the positioning groove 2 so as to apply a holding force to the spare part from the circumferential direction of the spare part when the spare part positioned in the positioning groove 2 is fixed.
[0041] It should be noted that the fixing fixture provided in this embodiment is used to fix, accurately position and support spare parts, and includes a base 1, a positioning groove 2 provided on the base 1, and a firmware component 3 provided on the base 1.
[0042] Specifically, the base 1 is the basic part of the fixed fixture, which is used to support and place other components. Optionally, in one possible implementation, the base 1 is large and thick, and has a flat surface to provide sufficient support area so that the entire fixed fixture remains stable during use and does not tilt or move easily. In addition, the shape of the base 1 is set according to actual needs. In this embodiment, the shape of the base 1 is not limited. Optionally, in one embodiment, the base 1 is generally a regular geometric shape, such as a rectangle, square, etc. In addition, in certain specific applications, the shape of the base 1 can be set according to the requirements of the spare parts to adapt to specific spare parts.
[0043] Furthermore, in one possible implementation, base 1 is made of a metal material. It is understood that the metal material used to make base 1 of the fixture is not fixed and can be selected based on actual needs. For example, in one embodiment, to ensure high strength and rigidity, as well as corrosion resistance, base 1 may be made of a titanium alloy. In another embodiment, base 1 may be made of a copper-zinc alloy or a copper-tin alloy.
[0044] For further information, please refer to Figure 1 The base 1 is provided with a positioning groove 2 for positioning the spare part and a fixing component 3 for fixing the spare part positioned in the positioning groove 2.
[0045] Specifically, the shape of positioning groove 2 matches the spare part to be secured, and its primary function is to precisely position the spare part, ensuring its accurate placement on the fixture. In other words, the shape, size, and overall contour of positioning groove 2 are designed based on the exterior shape of the spare part, ensuring that the spare part can be accurately placed within positioning groove 2 without shifting or shaking.
[0046] Specifically, the morphology of the positioning groove 2 has the following characteristics:
[0047] 1. The inner contour of the positioning groove 2 closely matches the outer contour of the spare part. That is, no matter whether the spare part has a regular geometric shape or an irregular shape, the shape of the positioning groove 2 accurately replicates the outer contour of the spare part so that the spare part can be placed in the positioning groove 2 smoothly.
[0048] 2. The depth of the positioning groove 2 is related to the thickness of the spare part to ensure that after the spare part is placed in the positioning groove 2, its surface is flush with the surface of the base 1, or slightly higher than the surface of the base 1 (to facilitate further operation or fixation).
[0049] Optionally, in a possible implementation, the spare part is a nozzle assembly, wherein the nozzle assembly includes a nozzle holder and a nozzle installed on the nozzle holder. At this time, the nozzle needs to be replaced. The nozzle assembly can be fixed by the fixing fixture, and then the nozzle is replaced to avoid damage to the nozzle holder.
[0050] Figure 3 This is a top view of a nozzle holder according to an exemplary embodiment of the present application. Figure 4 This is a front view of a nozzle holder shown in an exemplary embodiment of the present application. Figure 3 and Figure 4 The nozzle seat includes a seat body and a group of positioning pins.
[0051] At this time, please continue to refer to Figure 1 and Figure 2The positioning groove 2 includes a circular groove 21 for accommodating the seat body and at least one group of positioning pin slots 22 for accommodating the group of positioning pins; wherein,
[0052] When the suction nozzle assembly is positioned in the positioning groove 2, the seat body is accommodated in the circular groove 21; the group of positioning pins 42 is accommodated in any group of positioning pin card slots 22 in the at least one group of positioning pin card slots 22; wherein, when the suction nozzle assembly is accommodated in the positioning groove 2, the positioning pin card slots 22 clamp the suction nozzle assembly.
[0053] It should be noted that the number of at least one set of positioning pin slots 22 is set according to actual needs and is not limited in this embodiment. Figure 1 In the example shown, the positioning slot 2 includes two groups of positioning pin slots 22 .
[0054] Furthermore, each group of positioning pin slots 22 includes two slots, and the shape of each group of positioning pin slots 22 matches the shape of a group of positioning pins 42. The matching can be completely identical or adapted.
[0055] Please continue to refer to Figure 3 and Figure 4 , a set of positioning pins on the nozzle assembly includes a long positioning pin and a short positioning pin.
[0056] Optionally, in one embodiment, as Figure 1 As shown, the shape of each slot constituting the at least one group of positioning pin slots 22 is the same, and the shape of the slot matches the shape of the long positioning pin in the group of positioning pins.
[0057] Further, Figure 5 This is a schematic diagram of a fixing fixture shown in another exemplary embodiment of the present application, please refer to Figure 5 ,exist Figure 5 In the example shown, the shape of each group of positioning pin slots 22 in the at least one group of positioning pin slots 22 matches the shape of the group of positioning pins; each group of positioning pin slots 22 includes a slot for accommodating the long positioning pins and a slot for accommodating the short positioning pins.
[0058] In other words, in a possible implementation, the positioning groove 2 includes a group of positioning pin slots 22, and the morphology of the group of positioning pin slots 22 is as follows: Figure 3 As shown, for example, in another possible implementation, the positioning slot 2 includes a group of positioning pin slots 22, and each slot constituting the group of positioning pin slots 22 has the same shape, and the shape of the slot matches the shape of the long positioning pin in the group of positioning pins. Figure 1As shown, the positioning slot 2 includes two groups of positioning pin slots 22. The shape of each slot in each group of positioning pin slots 22 is the same, and the shape of the slot matches the shape of the long positioning pin in the group of positioning pins. Figure 5 As shown, the positioning groove 2 includes two groups of positioning pin retaining grooves 22 , and the shape of each group of positioning pin retaining grooves 22 matches the shape of a group of positioning pins.
[0059] Referring to the previous description, it can be understood that a group of positioning pin slots 22 includes two positioning pin slots. When the shapes of the two positioning pin slots are the same, the shapes of the slots need to match the shapes of the long positioning pins in a group of positioning pins on the nozzle assembly (that is, each group of positioning pin slots includes two long slots), so that a group of positioning pins on the nozzle assembly can be placed into the positioning pin slots 22 to achieve the positioning of the nozzle assembly. Further, when the shape of each group of positioning pin slots 22 matches the shape of a group of positioning pins on the nozzle assembly, at this time, referring to Figure 3 Each group of positioning pin slots 22 includes a slot for accommodating a long positioning pin in a group of positioning pins of the nozzle assembly and a slot for accommodating a short positioning pin in a group of positioning pins of the nozzle assembly, that is, each group of positioning pin slots 22 includes a long slot and a short slot.
[0060] It should be noted that, as described above, the number of groups of positioning pin slots 22 is not fixed and can be set according to actual needs. For example, in one embodiment, the number of groups of positioning pin slots 22 can be 2, and in another embodiment, the number of groups of positioning pin slots can be 3.
[0061] It should be noted that the number of groups of positioning pin slots can be greater than or equal to the number of groups of positioning pins on the nozzle assembly, so as to increase the scope of application of the fixing fixture.
[0062] For further information, please refer to Figure 1 The base 1 is also provided with a fixing component 3 for fixing the suction nozzle component positioned in the positioning groove 2. During the fixing process, the fixing component 3 applies a clamping force from the circumference of the spare part (i.e. along the periphery of the spare part) to keep the spare part stably in the positioning groove 2.
[0063] It should be noted that, in one possible implementation, the fixing assembly 3 may include adjustable components, such as screws, pressure plates, clamping devices, etc., to accommodate spare parts of different sizes and shapes. Furthermore, in another possible implementation, the fixing assembly 3 may include an adjustment mechanism (such as a knob, nut, etc.) and a locking mechanism to change the force applied by the fixing assembly 3 through adjustment.
[0064] In addition, the fixing assembly 3 can be arranged around the periphery of the positioning groove 2 to apply a clamping force in multiple directions. For example, in one possible implementation, the spare part can be clamped from multiple directions by multiple evenly distributed clamping blocks.
[0065] Furthermore, in a possible implementation, the contact surface between the fixing component 3 and the spare part may be covered with a flexible material (such as rubber or plastic) to prevent damage to the surface of the spare part.
[0066] Optionally, in a possible implementation, the main body of the fixing component 3 is made of metal material to ensure that the shape remains unchanged when the clamping force is applied, thereby improving the stable fixing effect.
[0067] The working principle of this fixture is as follows: by matching the shape and size of the positioning groove 2 with the spare part, the spare part is placed in the positioning groove 2 for preliminary positioning. Then, the fixing component 3 surrounds the positioning groove 2 and fixes the spare part in the positioning groove by applying appropriate clamping force to prevent it from moving or deviating, thereby achieving reliable fixation of the spare part.
[0068] The fixing jig provided in this embodiment for replacing spare parts of mounting equipment is provided with a base, further provided with a positioning groove and a fixing assembly on the base, and the shape of the positioning groove is matched to the shape of the spare part, and the fixing assembly is arranged around the positioning groove. In this way, the spare part can be placed in the positioning groove, and the fixing assembly is used to apply a clamping force to the spare part placed in the positioning groove to ensure that the spare part is stably fixed in the fixing jig, preventing damage to the spare part caused by the use of pliers or the like to fix the spare part. In addition, using this fixing jig to fix the spare part can also speed up the replacement of spare parts, reduce the complexity of the operation, and improve replacement efficiency.
[0069] For further information, please refer to Figure 1 and Figure 5 In one possible implementation, the fixing assembly 3 includes a plurality of fixing plates 31; the plurality of fixing plates 31 are fixed to the base 1 by fastening bolts 32; wherein, the plurality of fixing plates 31 can be moved along the circumference away from the spare part positioned in the positioning groove or the circumference close to the spare part positioned in the positioning groove, so that when the spare part positioned in the positioning groove 2 is fixed, the plurality of fixing plates 31 can hold the spare part tightly and apply a holding force to the spare part.
[0070] Figure 6 This is a schematic diagram of a fixing plate shown in an exemplary embodiment of the present application, please refer to Figure 6 . Figure 6 Figure (a) is a top view of the fixed plate. Figure 6 Figure (b) is the main view of the fixing plate. Figure 6The fixing assembly 3 achieves precise fixation of the spare parts in the positioning groove 2 through a combination of multiple adjustable fixing plates 31 and fastening bolts 32.
[0071] Specifically, the plurality of fixing plates 31 are fixed to the base 1 in a detachable connection manner.
[0072] The fixing plate 31 is connected to the base 1 via fastening bolts 32, allowing for quick removal and replacement according to different needs. Furthermore, the design of the fixing plate 31 is determined based on practical needs and is not limited in this embodiment. During implementation, the appropriate design of the fixing plate 31 (e.g., different shapes, sizes, or clamping structures) can be selected based on the characteristics of different spare parts to optimize the fixing effect.
[0073] Please continue to refer to Figure 6 ,exist Figure 6 In the illustrated implementation, each fixing plate 31 is provided with one or more bolt holes for fixing the fixing plate 31 to the base 1 by means of fastening bolts 32. These bolt holes allow the fixing plate 31 to move circumferentially away from the suction nozzle assembly positioned in the positioning groove 2 or circumferentially close to the suction nozzle assembly positioned in the positioning groove 2, thereby realizing the release and fastening of the suction nozzle assembly fixed in the positioning groove 2.
[0074] In practice, when the position of the fixing plate 31 needs to be adjusted, the operator can loosen the fastening bolts 32 on the fixing plate 31 to slide the fixing plate 31 along the direction of the bolt hole to a suitable position, and then re-tighten the fastening bolts 32 to fix the fixing plate 31 in the new position.
[0075] Specifically, the fixing assembly 3 includes a plurality of fixing plates 31 , and the plurality of fixing plates 31 are arranged at different positions on the base 1 to fasten the spare parts from different directions.
[0076] In a specific implementation, a plurality of fixing plates 31 can be arranged in a circular or annular shape around the periphery of the positioning groove 2 , and each fixing plate 31 is evenly spaced.
[0077] For example, in Figure 1 and Figure 5 In the example shown, when the positioning slot 2 includes two groups of positioning pin slots 22 , the fixing assembly 3 includes four fixing pieces 31 ; the four fixing pieces 31 are spaced apart between the four slots constituting the two groups of positioning pin slots 22 .
[0078] Further, please continue Figure 3 and Figure 4In one possible implementation, when the spare part is a nozzle assembly, the seat body of the nozzle seat has a boss. When the fixing component 3 fixes the nozzle assembly positioned in the positioning groove 2, the fixing component 3 applies a clamping force to the nozzle assembly from the circumference of the boss.
[0079] Specifically, referring to the previous description, when the fixing assembly 3 fixes the nozzle assembly positioned in the positioning groove 2, the fixing piece 31 moves along the circumference of the nozzle assembly positioned in the positioning groove 2, and multiple fixing pieces 31 hold the nozzle seat of the nozzle assembly tightly, applying a holding force to it, and fixing the entire nozzle assembly. Please continue to refer to Figure 1 、 Figure 3 and Figure 4 The position where the fixing plate 31 applies the clamping force to the nozzle seat is the boss position on the seat body, and accordingly, the fixing plate 31 has a groove at the position corresponding to the boss position, which can effectively clamp the boss position of the seat body, making the nozzle assembly more firmly fixed.
[0080] It can be understood that in order to adapt to different bosses, grooves of different shapes can be designed to effectively enhance the effect of the fixing plate 31 in applying the clamping force, so that the nozzle assembly is fixed more firmly. In addition, by designing a groove that matches the boss of the base body, the physical damage caused by the clamping contact can be effectively reduced, the wear of the fixing plate 31 and the nozzle assembly can be reduced, and the service life of the fixing plate 31 and the nozzle assembly can be improved.
[0081] The following combination Figure 1 and Figure 5 , the working principle of the fixed fixture for replacement of placement equipment spare parts provided in this application is introduced in detail:
[0082] Please refer to Figure 1 and Figure 5 It can be understood that when the spare part is a nozzle assembly, the fixing fixture is a fixing fixture for replacing the nozzle of the placement equipment, which is used to fix the nozzle assembly.
[0083] Furthermore, the fixing fixture is provided with a base 1 and a positioning groove 2 on the base 1 for positioning the nozzle assembly. The shape of the positioning groove 2 matches the shape of the nozzle assembly. The positioning groove 2 includes a circular groove 21. The nozzle assembly is placed into the positioning groove 2 to achieve positioning of the nozzle assembly.
[0084] In addition, the nozzle assembly is provided with a group of positioning pins, each group of positioning pins includes a long positioning pin and a short positioning pin, and the positioning groove 2 also includes at least one group of positioning pin card slots 22 to achieve further positioning and fixation of the nozzle assembly.
[0085] Furthermore, the fixing fixture is also provided with a fixing component 3 for fixing the suction nozzle assembly positioned in the positioning groove 2. The fixing component 3 is composed of multiple fixing plates 31. The fixing plates 31 are dynamically fixed to the base 1 by fastening bolts 32 to achieve the tightness of the suction nozzle assembly.
[0086] In addition, please continue to refer to Figure 5 The positioning groove 2 contains two groups of positioning pin slots 22. There are four fixing plates 31 that make up the fixing assembly 3, which are respectively located at four positions of the base 1 and are spaced between the four slots 22 that make up the two groups of positioning pin slots 22. They collectively point to the suction nozzle assembly fixed in the circular groove 21 to apply a clamping force to the suction nozzle assembly from the circumferential direction.
[0087] Furthermore, by loosening or tightening the fastening bolts 32 of the fixing plate, the fixing plate 31 can be moved on the base 1. By moving the fixing plate 31 circumferentially toward the nozzle assembly positioned in the positioning groove 2, the fixing plate 31 can be fitted to the nozzle assembly. When the fixing plate 31 and the nozzle assembly are tightly fitted, the fastening bolts 32 are adjusted to tighten them. At this time, multiple fixing plates 31 jointly hold the nozzle assembly in the positioning groove 2, applying a holding force thereto, thereby fixing the nozzle assembly. Furthermore, the fastening bolts 32 can be loosened to allow the fixing plate 31 to move circumferentially away from the nozzle assembly positioned in the positioning groove 2, loosening the fixing plate 31 that holds the nozzle assembly in the positioning groove 2, and removing or replacing the nozzle assembly.
[0088] The fixing fixture provided in this embodiment can avoid damage to the spare parts.
[0089] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
