[0002] Epoxy molding compound is made by injection molding, and the mold used for injection molding is composed of a fixed mold and a movable mold. Since there is a gap between the mold cavities of the fixed mold and the movable mold, flash will be formed around the epoxy molding compound after it is cooled and formed, which is not conducive to the packaging of integrated circuits. To solve this problem, in the process of designing the mold of epoxy molding compound, a model of the epoxy molding compound is first made by the mold, and then the flash of the model is tested on a test bench to facilitate designers to improve the mold. However, when the existing epoxy molding compound test bench performs flash testing on the model of epoxy molding compound, the flash test can only be performed from one side of the model, the test range is relatively small, and the test data error is relatively large, which affects the efficiency of later mold improvement.

[0003] The existing patent application number: 202223426168.8 discloses a flash testing device for epoxy molding compounds. When the device is used, the model of the epoxy molding compound to be tested is first placed in a placement groove, and then the bottom of the inner wall of the placement groove and the bottom of the model are evacuated through an air pump, a conduit, a suction cup and a through hole, so that a negative pressure suction force is formed between the two, thereby improving the fixing efficiency of the model.

[0036] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0037] like Figures 1 to 4 As shown, an epoxy molding compound testing workbench includes a workbench 1 for testing epoxy molding compound, a CCD detector 5 is provided on the workbench 1, and the epoxy molding compound testing workbench also includes:

[0038] The test piece 2 is rotatably sleeved with the limiting hole 7 provided on the workbench 1, and the test piece 2 is used to take pictures of the epoxy molding compound.

[0039] Test piece 2 includes:

[0040] The support shaft 21 is rotatably sleeved in the limiting hole 7 , and a middle hole 26 penetrating from top to bottom is provided on the top of the support shaft 21 .

[0041] A support plate 22 is fixed to the top of the support shaft 21 .

[0042] A semicircular guide rail 24 is vertically fixed on the support plate 22 .

[0043] The sliding sleeve is arranged on the semicircular guide rail 24 to carry the electric slide 25 of the CCD camera.

[0044] A flat gear 27 is fixed to the bottom of the support shaft 21 .

[0045] A clamping member 3 is provided on the workbench 1 for fixing the epoxy molding compound.

[0046] A power chamber 4 is arranged on one side of the workbench 1 .

[0047] The support rod 6 is vertically fixed inside the power chamber 4, and the top end of the support rod 6 passes through the middle hole 26 from bottom to top.

[0048] A suction cup 8 is provided at the free end of the clamping member 3 and the top end of the support rod 6 for adsorbing and fixing the epoxy molding compound.

[0049] A driving member 9 is arranged in the power chamber 4 and is used to drive the flat gear 27 to rotate.

[0050] After the epoxy molding material is fixed, the electric slide 25 is controlled to stop at different positions on the semicircular guide rail 24, and then the flat gear 27 is driven to rotate through the driving member 9. The rotating flat gear 27 will drive the semicircular guide rail 24 to rotate synchronously through the support shaft 21 and the support plate 22, so that the CCD camera can take pictures of the epoxy molding material at various angles in the vertical and circumferential directions, and then the taken pictures are transmitted to the CCD detector 5, so as to improve the comprehensiveness and accuracy of data collection, so as to speed up the researchers' improvement progress on the mold in the later stage.

[0051] In this embodiment, the test piece 2 includes a support column 23 fixed on the support plate 22, and the top of the support column 23 is fixed on the semicircular guide rail 24. Since the semicircular guide rail 24 is vertically arranged on the support plate 22, there is only one connection point between it and the top of the support plate 22, and the stability and supporting strength are poor. By setting the support column 23, the supporting strength and stability of the semicircular guide rail 24 are enhanced to prevent the semicircular guide rail 24 from shaking significantly when the electric slide 25 moves and the support plate 22 rotates, thereby affecting the shooting accuracy of the CCD camera.

[0052] In this embodiment, the bottom of the support column 23 is located at the boundary of the support disk 22, and the support column 23 is tangent to the outside of the semicircular guide rail 24, so that an approximately triangular support surface is formed between the support column 23, the support disk 22 and the semicircular guide rail 24, thereby improving the stability and support strength of the semicircular guide rail 24, and preventing the semicircular guide rail 24 from shaking significantly when the electric slide 25 moves and the support disk 22 rotates, thereby affecting the shooting accuracy of the CCD camera.

[0053] In this embodiment, the support rod 6 and the support plate 22 are coaxial, and the top end of the support rod 6 is close to the center of the semicircular guide rail 24. After the epoxy molding material is fixed, the CCD camera on the electric slide 25 can take pictures from any thermal angle between the top and the bottom of the epoxy molding material. At the same time, the semicircular guide rail 24 and the electric slide 25 thereon are driven to rotate synchronously through the support plate 22. The electric slide 25 can be positioned at any thermal angle between the top and the bottom of the epoxy molding material, thereby realizing comprehensive photography of the epoxy molding material and improving the comprehensiveness and accuracy of data collection.

[0054] In this embodiment, the clamping member 3 includes:

[0055] A support base 31 is fixed on the workbench 1 , and a mounting groove 32 is provided on the support base 31 . Transverse holes 33 are provided on opposite surfaces of the mounting groove 32 .

[0056] The horizontal shaft 34 is rotatably sleeved in the horizontal hole 33 .

[0057] A clamping arm 36 is fixed between the two transverse shafts 34 .

[0058] The torsion spring 35 is sleeved on the outside of the transverse shaft 34 , and the two ends of the torsion spring 35 are respectively fixed on the transverse shaft 34 and the support seat 31 .

[0059] When the epoxy molding plastic is fixed, first push the top end of the clamping arm 36 laterally to deflect it by a certain angle with the horizontal axis 34 as the deflection axis. During this process, the torsion spring 35 undergoes elastic deformation and accumulates elastic torque, so that the suction cup 8 at the free end of the clamping arm 36 is separated from the suction cup 8 at the top end of the support rod 6. Then the epoxy molding plastic is pressed and placed on the top of the suction cup 8 at the top end of the support rod 6. The suction cup 8 initially adsorbs the column epoxy molding plastic. Then release the hand that pushes the clamping arm 36. Under the combined action of the gravity of the clamping arm 36 and the torsion of the torsion spring 35, the free end of the clamping arm 36 is automatically reset, and the suction cup 8 at the free end adsorbs and fixes the top of the epoxy molding plastic, thereby improving the efficiency and fixing effect of the fixing operation of the epoxy molding plastic, and preventing the clamping arm 36 and the support rod 6 from blocking the shooting angle of the CCD camera.

[0060] In the present embodiment, one side of the mounting groove 32 is open, and the open opening and the support plate 22 are respectively located on both sides of the clamping arm 36. This design allows the free end of the clamping arm 36 to deflect normally in a direction away from the support plate 22 when the epoxy molding material is clamped and fixed, and the clamping arm 36 can be restricted when it is reset to maintain its state, thereby avoiding affecting its stability in clamping and fixing the epoxy molding material.

[0061] The above description is only the preferred embodiment of the utility model, and the parts not described in the utility model can be implemented by adopting or drawing on existing technologies. Of course, the above description is not a limitation of the utility model, and the utility model is not limited to the above examples. The changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the utility model should also fall within the protection scope of the utility model.
