Description

Technical Field

[0001] The utility model relates to the technical field of optical coupling plastic sealing, in particular to an optical coupling plastic sealing sheet arrangement frame. Background Art

[0002] The optocoupler plastic sealing film arrangement rack is used to arrange the films of the optocoupler brackets during the plastic sealing process. However, the current film arrangement rack structure is mainly a handheld frame with multiple holes arranged in the frame. Two support rods for supporting and positioning the optocoupler brackets are fixed in the holes by bolts. The optocoupler brackets are placed on the two support rods. For this structure, when plastic sealing films are arranged for different optocoupler brackets, due to the differences in the positioning holes on the optocoupler brackets, and the support rods of this structure also have fixed positioning positions for the optocoupler brackets, different film arrangement racks need to be replaced. Therefore, when there are many types of optocoupler brackets, the cost of making the film arrangement rack is also relatively high. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides an optically coupled plastic-sealed film rack, which solves the problem that the current film rack structure is relatively fixed and difficult to adapt to optically coupled brackets of different structures, thereby requiring the storage of different types of film racks, resulting in high costs.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A photocoupler plastic-sealed film row rack comprises a frame assembly as a mounting carrier, wherein a plurality of film row holes are arranged in the frame assembly, and limiting grooves are arranged on the side walls around the film row holes, and a film row frame is detachably positioned and installed in the limiting grooves, and an avoidance hole is opened on the film row frame, and two groups of mutually parallel photocoupler support rods are symmetrically installed on the inner walls of the avoidance holes, and at least two photocoupler support rods in the same group of photocoupler support rods are provided with positioning columns for positioning the photocoupler brackets.

[0006] Preferably, the limiting groove is an L-shaped limiting surface for limiting the bottom and side surfaces of the film arrangement frame.

[0007] Preferably, the sheet-dispensing hole is rectangular, and there are a plurality of limiting grooves which are L-shaped and arranged at each corner of the sheet-dispensing hole.

[0008] Preferably, at least one side of the inner wall of the sheet discharging hole is provided with a discharge groove for taking out the sheet discharging frame.

[0009] Preferably, the optical coupling support rods in the same group are evenly distributed and the number is at least 3.

[0010] Preferably, the plurality of optical coupling support rods are all provided with a bending portion located on the same plane.

[0011] Preferably, the frame assembly comprises a film arrangement frame provided with film arrangement holes, a plurality of weight reduction holes are provided on the film arrangement frame, and a grab bar for grabbing is installed on the film arrangement frame.

[0012] Preferably, a plurality of elastic members for cooperating with each other to squeeze and fix the sheet arrangement frame are installed in the side walls of the limiting groove.

[0013] Compared with the prior art, the utility model provides an optically coupled plastic-sealed film rack, which has the following beneficial effects:

[0014] 1. By cooperating with the limiting grooves on the inner walls around the film arrangement holes and positioning the film arrangement frame detachably installed therein, compared with the prior art method of replacing the entire film arrangement frame when plastic-sealing the optocoupler brackets with different positioning positions, only the overall result of the film arrangement frame, the optocoupler support rod and the positioning column needs to be replaced. Therefore, the replacement cost is relatively lower. Moreover, when the film arrangement frame, the optocoupler support rod and the positioning column are made of light materials such as aluminum alloy, the overall structure can be made lighter, and the frame assembly can still use relatively strong materials, thereby ensuring its rigidity during use to ensure the plastic sealing effect of the optocoupler bracket.

[0015] 2. By providing a discharge groove on the side wall of the limit groove, on the one hand, the weight of the frame assembly is reduced. On the other hand, when the frame assembly needs to be replaced, the film arrangement frame can be replaced conveniently by pinching the film arrangement frame on the side with hands. At the same time, the limit groove is an L-shaped limit surface for limiting the bottom and side surfaces of the film arrangement frame, and then cooperated with the elastic part, the positioning and fixation of the film arrangement frame can be better achieved, and replacement is also convenient.

[0016] 3. By providing a bent portion on the optical coupling support rod, the contact area between the optical coupling support rod and the surface of the optical coupling bracket can be increased, thereby better supporting the optical coupling bracket and better preventing deformation of the optical coupling bracket.

DETAILED DESCRIPTION

[0025] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] In order to solve the problem that the current film row frame structure is relatively fixed and difficult to adapt to optical coupling brackets of different structures, thus requiring the storage of different types of film rows and resulting in high costs, the utility model provides an optical coupling plastic sealed film row frame, wherein a plurality of film row holes 2 are arranged in a frame assembly 1, and limiting grooves 3 are arranged on the side walls around the film row holes 2, and a film row frame 4 is detachably positioned and installed in the limiting grooves 3, and an avoidance hole 5 is opened on the film row frame 4, and two groups of mutually parallel optical coupling support rods 6 are symmetrically installed on the inner wall of the avoidance hole 5. For the convenience of processing, the optical coupling support rods 6 are usually integrally formed on the film row frame 4, and at least two optical couplings are included in the same group of optical coupling support rods 6. The support rod 6 is provided with a positioning column 7 for positioning the optical coupling bracket. For optical coupling brackets with different positioning positions, during production and processing, it is only necessary to take out the film arrangement frame 4, the optical coupling support rod 6 and the positioning column 7 as a whole, and replace the overall part that matches the optical coupling bracket to be processed. In order to ensure the applicability of the entire film arrangement frame, the frame assembly 1 is generally made of iron material, and the film arrangement frame 4, the optical coupling support rod 6 and the positioning column 7 as a whole are made of aluminum alloy material, thereby ensuring that the overall firmness of the film arrangement frame can be ensured, and the weight of the film arrangement frame can be ensured to be light, which is convenient for employees to use. Compared with overall replacement, only replacing the aluminum alloy part is relatively cheaper.

[0027] When the film arrangement frame 4 is arranged in the limiting groove 3, in order to achieve a quick positioning effect on the film arrangement frame 4, the limiting groove 3 is made into an L-shaped limiting surface for limiting the bottom and side surfaces of the film arrangement frame 4, so that the L-shaped limiting surface is fitted with the bottom and side surfaces of the film arrangement frame 4 for limiting the position, thereby preventing the optical coupling bracket from being placed on the optical coupling support rod 6 and causing the film arrangement frame 4 to shake, resulting in inaccurate position during plastic sealing.

[0028] When the limiting grooves 3 are spread all over the inner wall around the entire row of film holes 2, the processing difficulty is relatively large. In order to reduce the processing difficulty while ensuring the positioning effect of the row of film frames 4, the row of film holes 2 are made rectangular, and there are several limiting grooves 3 and they are L-shaped and arranged at each corner of the row of film holes 2. Thereby, the total processing area of ​​the limiting grooves 3 can be reduced to reduce the processing difficulty, and the row of film frames 4 are positioned by the limiting grooves at the four corners, which also has the same positioning effect.

[0029] When the film ejection frame 4 is installed in the film ejection hole 2, there may be a lack of force points to take out the film ejection frame 4, so a discharge chute 8 for taking out the film ejection frame 4 is provided on at least one side of the inner wall of the film ejection hole 2, which is convenient for pinching the film ejection frame 4 to take it out, and on the other hand, it also reduces the weight of the frame assembly 1, making it easier for workers to use it.

[0030] When the optocoupler bracket is placed on the same group of optocoupler support rods 6, since the thickness of the optocoupler bracket is relatively small, generally about 0.2 mm, and the length is generally above 240 mm, when the number of optocoupler support rods 6 is small, the optocoupler bracket may bend. Therefore, after experiments, the same group of optocoupler support rods 6 are evenly distributed and the number is at least 3, which can well ensure that when the optocoupler bracket is placed on multiple optocoupler support rods 6, the probability of deformation can be greatly reduced, thereby ensuring the plastic sealing effect of the optocoupler bracket.

[0031] When the optocoupler support rod 6 is a light rod, the contact area with the optocoupler bracket is small, so the supporting force of the optocoupler bracket is small, and the surface of the optocoupler support rod 6 may be difficult to fully contact with the optocoupler bracket. Therefore, a bending portion a located on the same plane is provided on multiple optocoupler support rods 6 to ensure the supporting area and supporting effect of the optocoupler bracket.

[0032] The frame assembly 1 includes a film arrangement frame 11 provided with film arrangement holes 2, a plurality of weight reduction holes 12 are provided on the film arrangement frame 11, and a grab bar 13 for grabbing is installed on the film arrangement frame 11 to facilitate employees to hold the grab bar 13 by hand for operation.

[0033] When the film-element frame 4 is placed in the limiting groove 3 and fixed with bolts and other parts, it is not convenient to quickly switch the film-element frame 4. Therefore, a plurality of elastic parts 9 are installed in the side walls of the limiting groove 3 for cooperating with each other to squeeze and fix the film-element frame 4. The elastic parts 9 can ensure that there is a gap between the film-element frame 4 and the limiting groove 3 to prevent shaking, and can realize quick replacement of the film-element frame 4 on the other hand.

[0034] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0035] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
