Description

Technical Field

[0001] The utility model relates to the field of aluminum plating of film substrates, in particular to a fixture for unloading a crucible. Background Art

[0002] For example, patent No. 201510298119.6 is named as a new type of high-efficiency aluminum plating equipment, which is used to perform aluminum plating on the film.

[0003] In this equipment, there is boron nitride material in the crucible. Boron nitride material is a consumable. After a period of use, the entire crucible needs to be replaced.

[0004] However, replacing the crucible is a very difficult matter. Figure 3 The positive electrode and negative electrode connected to the crucible are in close contact with the crucible. The effect of this close contact comes from other clamping mechanisms. The spring used in the clamping mechanism has a large spring constant. Therefore, to unload the crucible, the spring must be compressed. It is very difficult to compress the spring with a large spring constant. At present, the manual instrument for unloading the crucible is not dedicated to unloading the crucible, but is used in coordination with existing instruments. Therefore, unloading the crucible is a rather troublesome and inconvenient thing. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a fixture for unloading a crucible, which is used to solve the problem of the inconvenience of unloading the crucible in the traditional way.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a jig for unloading a crucible, characterized in that it includes a first pushing member and a second pushing member that are slidably connected to each other, and an ejection component arranged on the first pushing member and slidingly pushing the second pushing member, and the ejection component is connected to a push handle.

[0007] Furthermore, a spring is also included, and two ends of the spring are respectively connected to the first pushing component and the second pushing component.

[0008] Furthermore, the first pushing member is a pair of first top plates, and the second pushing member includes a pair of second top plates and a connecting base. The two first top plates are spaced apart, and the second top plates are also spaced apart. Any first top plate is independent and accommodated in any second top plate, and is slidably connected to the second top plate. The upper edges of the second top plates are connected through the connecting base.

[0009] Furthermore, the rear end of the second pushing member has a thickness capable of intersecting with the moving track of the ejection component.

[0010] Furthermore, the ejection assembly is composed of a rotating block and a bearing connected in a staggered and parallel manner through a rotating axis. The rotating block is embedded in the first pushing member, the end surface of the bearing is connected to the end surface of the rotating block by screws, and the push handle is fixed on the bearing.

[0011] Furthermore, the push handle extends above the first pushing member.

[0012] Furthermore, a buffer is provided at the front end of the first pushing member and the rear end of the second pushing member.

[0013] Beneficial effects of the utility model:

[0014] It is not difficult to see that the utility model uses the form of an inner push plate to open the contact relationship between the positive electrode, the negative electrode and the crucible. During the opening process, the eccentric rotation drive mode of the ejection component just meets the movement process of executing the inner push plate. Combined with the use of the push handle, this method of pushing the push plate open is very labor-saving when the torque becomes longer. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 1 This is a fixture for unloading a crucible of the utility model. Figure 2 This is the status diagram of the fixture in the aluminum plating equipment. The crucible E is connected to the positive and negative electrodes D. Figure 1The jig shown includes a first pushing member 1 and a second pushing member 2 having a sliding relationship with each other. The first pushing member 1 and the second pushing member 2 are arranged in the evaporation mechanism and abut against the baffle F. In this embodiment, an ejection member 3 is arranged on the first pushing member 1 to perform eccentric rotational motion. After the arc-shaped motion trajectory thereof contacts the second pushing member 2, the second pushing member 2 is driven away from the first pushing member 1. The ejection member 3 is connected to a push handle 4.

[0024] like Figure 2-3 As shown, it is not difficult to see that the utility model uses the form of an inner push plate F to open the contact relationship between the positive electrode, the negative electrode D and the crucible E. During the opening process, the eccentric rotation driving method performed by the ejection component 3 just meets the movement process of executing the inner push plate F. In combination with the use of the push handle 4, when the torque becomes longer, this method of opening the push plate F is very labor-saving.

[0025] In the embodiment, a spring 5 is also included, and both ends of the spring 5 are respectively connected to the first pushing member 1 and the second pushing member 2. The spring 5 is used to reset the positional relationship between the first pushing member 1 and the second pushing member 2. After the crucible E is replaced, the spring 5 pulls the first pushing member 1 and the second pushing member 2 towards each other through the contraction of its own stress, and the position of the baffle F is reset, and the positive and negative electrodes D are in close contact with the crucible E again.

[0026] In this embodiment, two ends of the spring 5 are connected to the upper edges of the first pushing member 1 and the second pushing member 2 respectively.

[0027] like Figure 4-5 As shown, the first pushing member 1 is a pair of first top plates 100a, and the second pushing member 2 is a pair of second top plates 200a. The two first top plates 100a are arranged at intervals, and the second top plates 200a are also arranged at intervals. Any first top plate 100a is independent and accommodated in any second top plate 200a, and is slidably connected to the second top plate 200a (the rear end 2-a of the second pushing member 2 is provided with a channel T connected to the interior thereof, and the front end 1-a of the first pushing member 1 penetrates into The second top plate 200a is connected to the passage T at its upper edge by a connecting base 200b; the spacing in the above scheme is to prevent the crucible E from being taken out of the jig, and when the crucible E is unloaded, the crucible E is taken out from the space between the first top plates 100a; it should be noted that when the jig is used to eject the push plate F, the jig is located above the crucible E and between the first top plates 100a, or the crucible E is located in the jig and between the first top plates 100a.

[0028] from Figure 4It can be seen that the rear end 2-a of the second pushing member 2 has a thickness that intersects with the moving track of the ejection member 3, so when the ejection member 3 rotates, it can contact the second pushing member 2 and push the second pushing member 2 to move toward the baffle F;

[0029] It should be noted here that the positions of the negative electrode D and the positive electrode (not shown in the figure) are relative, and the positive and negative electrodes 6 each correspond to a push plate F, and the push plates F also each correspond to the use of a clamping mechanism. When the above-mentioned rear end 2-a pushes the second pushing member 2 to move in the direction of the baffle F, the first pushing member 1 moves in the opposite direction of the second pushing member 2 due to the contact between the ejection part 3 and the rear end 2-a, thereby pushing the baffle F on the other side.

[0030] The ejection assembly 3 is composed of a rotating block 3a and a bearing 3b connected in a staggered and parallel manner through the rotating axes. In the embodiment, the rotating block 3a is embedded in the first pushing member 1. The rotating block 3a and the bearing 3b are both cylinders. The end face of the bearing 3b is connected to the end face of the rotating block 3a by screws. The end of the push handle 4 is a connecting seat 41, and the connecting seat 41 is fixed on the other end face of the bearing 3b. When the push handle 4 is pressed, the movement trajectory of the bearing 3b is arc-shaped. In addition, the purpose of using the bearing 3b is based on the fact that the friction coefficient of rolling friction is smaller than that of sliding friction, which can reduce the loss of the second pushing member 2.

[0031] It should be noted that the push handle 4 extends above the first pushing member 1 .

[0032] It should also be noted that the rear end of the first pushing member 1 and the front end of the second pushing member 2 are provided with a buffer 6, and the buffer 6 is used to avoid direct contact between the first pushing member 1, the second pushing member 2 and the push plate F, thereby avoiding direct contact between the two and causing wear between each other.

[0033] like Figure 6-8 As shown, various state diagrams of the utility model when in use are shown.

[0034] Figure 6 It is a stereogram of the utility model in the initial state.

[0035] When in use, pull the push handle 4 to flip it to the right of the drawing to obtain Figure 7 The status shown in Figure 7 It can be seen that the position of the connection seat 41 has changed. Figure 8 This is a state diagram of the final position of the bearing 3b after pushing the second pushing member 2.

[0036] It should be noted that Figure 6-8 The bearing 3b is not shown.

[0037] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
