Description
Technical Field
[0001] The invention relates to a cleaning effect inspection device, in particular to a dispensing head cleaning effect inspection device, and belongs to the technical field of semiconductor packaging. Background Art
[0002] The chip loading process in the semiconductor packaging process is to load the chip onto the fixed area base island of the substrate and frame according to the position requirements of the drawing; during the fixing process, it is necessary to pre-draw glue on the lead frame and substrate fixing area.
[0003] Therefore, the dispensing head needs to be cleaned after being used for a period of time.
[0004] Currently, after the dispensing head is cleaned, the cleaning effect is manually confirmed under a light, but the cleaning effect cannot be directly and effectively confirmed. Summary of the invention
[0005] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a device for inspecting the effect of a dispensing head of a wafer loader after cleaning.
[0006] In order to achieve the above object, the present invention adopts the following technical solution:
[0007] A device for inspecting the cleaning effect of a dispensing head comprises a detection table, wherein a table top of the detection table is provided with a plurality of mounting holes for fixing the dispensing head, and a lamp head for irradiating the mounting holes is provided at the bottom of the table top.
[0008] The above-mentioned mounting holes are threaded holes.
[0009] The plurality of mounting holes are distributed in a ring shape on the table top.
[0010] Furthermore, there are several distributed rings, each based on the same center and different radii.
[0011] The table top is provided with marks corresponding to the mounting holes.
[0012] Furthermore, the lamp caps are distributed in a ring shape, and the outer ring of the lamp caps is provided with a ring-shaped anti-leakage halo.
[0013] A parallel light projection board is arranged on the top of the table.
[0014] The bottom axis of the detection platform is provided with a supporting bottom plate.
[0015] The present invention is beneficial in that:
[0016] A device for inspecting the cleaning effect of a dispensing head of the present invention can fix a plurality of dispensing heads to be inspected through a table top, and judge whether the dispensing heads are cleaned by confirming whether the light spot formed by the transmitted light at the bottom on the light projection board forms the shape of the entire dispensing head, and quickly locate each dispensing head through the marks on the table top.
[0017] The device for checking the cleaning effect of a dispensing head of the present invention has a simple structure, is easy to use, has good detection effect and high efficiency. It can effectively solve the problems of unclean dispensing cleaning and waste of labor costs by checking the quality of the dispensing head after cleaning, and prevents the dispensing head that is not cleaned from being used on a machine, causing blockage of the dispensing head and causing abnormal phenomenon of poor dispensing. The device has strong practicality and wide applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.
[0022] A device for inspecting the cleaning effect of a dispensing head is composed of a detection platform 1, a light projection board 3 and a supporting bottom board 4.
[0023] The test table 1 is composed of a table top 8, a lamp holder 2 and a leak-proof halo 9. The table top 8 is provided with a plurality of through holes, and the inner side walls of the through holes are provided with threads, that is, the through holes are threaded holes, which are mounting holes 6 for fixing the dispensing head by threads.
[0024] The plurality of mounting holes 6 are sequentially arranged into a plurality of concentric circular rings with different radii. On the surface of the table top 8, there are marks 7 corresponding to the mounting holes 6, and preferably, the marks 7 can be serial numbers.
[0025] The lamp holder 2 arranged in a ring is arranged at the bottom of the table 8, and the light of the lamp holder 2 illuminates the mounting hole 6. A ring-shaped leakproof halo 9 for shading is arranged on the outer ring of the lamp holder 2. Preferably, the leakproof halo 9 can be screwed with the bottom of the table 8, and the lamp holder 2 is fixed to the bottom of the table 8. Preferably, a leakproof bottom plate is provided at the bottom of the leakproof halo 9, which further seals the lamp holder 2 at the bottom of the table 8 and protects it, and can seal the power module and control module for powering the lamp holder 2 at the same time, and the control switch of the control module can be set on the outer wall of the leakproof halo 9.
[0026] When using,
[0027] A plurality of dispensing heads are screwed into the mounting holes 6 via threads.
[0028] Turn on lamp head 2, illuminate the dispensing head, and use the transmitted light to confirm whether the inside of the dispensing head is clean. To facilitate the observation of the transmitted light, the transmitted light can be projected on any plane, and the size of the projected light spot can be used to determine whether there are any residual stains inside, forming a blockage that affects the transmitted light.
[0029] Preferably, the plane may be a light projection board 3 mounted on the top of the table 8 via a bracket 5 .
[0030] For a defective light spot, the corresponding dispensing head can be quickly selected through the mark 7 on the table 8, that is, the dispensing head that has not been cleaned or has a poor cleaning effect.
[0031] Preferably, the bottom of the detection platform 1 is axially connected to a pair of support rods 10, and the bottom ends of the support rods 10 are fixedly connected to the support base plate 4. The support base plate 4 is used to support the detection platform 1, and the detection platform 1 is rotated by a certain angle through the axis, so that the light projection board 3 forms a certain deflection angle relative to the longitudinal direction, which is convenient for observing the light spot projected on the bottom surface of the light projection board 3 from the side.
[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
