Description

Technical Field

[0001] This utility model relates to the field of tooling, and in particular to the field of needle positioning technology, specifically a device for confirming the position of the coating needle in an automatic coating equipment. Background Technology

[0002] Because the existing automatic coating equipment has a theoretical gap of 3mm between the needle position confirmation device and the needle, the distance in the Z direction of the needle can be confirmed by the go / no-go gauge, but the confirmation in the X and Y directions requires visual confirmation, which is prone to deviation. This causes the solder to be coated off-center during coating, resulting in defective products being produced and shipped out! Summary of the Invention

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a coating needle position confirmation device for an automatic coating equipment, so as to solve the difficulties of the prior art.

[0004] To achieve the above and other related objectives, this utility model provides a device for confirming the position of the coating needle in an automatic coating equipment, comprising:

[0005] The reference base 1 has a base section 11 at its bottom and a boss connecting ring 12 at its top. The boss connecting ring 12 has connecting holes 13 around its perimeter and bolts are inserted into the connecting holes 13.

[0006] XY position positioning cylinder 2, which is inserted through the center of the reference base 1;

[0007] Z-position positioning detection block 3 is placed on top of XY-position positioning cylinder 2 during detection.

[0008] According to the preferred embodiment, the reference base 1 has a travel through hole 14 in the center.

[0009] According to the preferred embodiment, the XY position positioning cylinder 2 is T-shaped and its bottom is locked in the travel through hole 14.

[0010] According to the preferred scheme, the XY position positioning cylinder 2 moves up and down along the stroke through hole 14.

[0011] According to the preferred embodiment, a cusp hole 21 is provided at the center of the top of the XY position positioning cylinder 2;

[0012] According to the preferred embodiment, the diameter of the tip position hole 21 is larger than the maximum outer diameter of the needle to be tested.

[0013] According to the preferred embodiment, the bottom of the XY position positioning cylinder 2 is provided with a needle tip clearance hole 22, which communicates with the tip position hole 21.

[0014] According to the preferred embodiment, the Z position positioning detection block 3 has a through side on the side near the pointed position hole 21 and a stop side on the other side. The height of the through side is less than the height of the stop side, and the difference between the height of the through side and the height of the stop side is 6mm.

[0015] This invention employs a reference base, an XY position positioning cylinder, and a Z position positioning detection block. The robot controls the coating needle to hover directly above the XY position positioning cylinder. The XY position positioning cylinder is manually moved upwards along the travel through-hole until the bottom of the coating needle can contact the top of the XY position positioning cylinder. The robot then checks if the bottom of the coating needle is correctly positioned in the center of the alignment hole. The Z position positioning detection block is then placed close to the travel through-hole, and its side is moved towards the alignment hole to detect the Z-axis position of the needle. This achieves the following beneficial effects:

[0016] (1) It is more accurate than conventional visual confirmation, and when the position deviates, there is a clear position as a reference for adjustment, which is more efficient.

[0030] This utility model proposes a device for confirming the position of a coating needle in an automatic coating equipment. It is used for needle positioning. This utility model does not limit the specifications and types of the coating needles to be positioned. However, the structure of the reference base 1, the XY position positioning cylinder 2, and the Z position positioning detection block 3 is particularly suitable for positioning the coating needles in an automatic coating equipment.

[0031] In general, the automatic coating equipment coating needle position confirmation device proposed in this utility model mainly includes: a reference base 1, an XY position positioning cylinder 2, and a Z position positioning detection block 3. (See also...) Figure 1 It shows the arrangement of the reference base 1, the XY position positioning cylinder 2 and the Z position positioning detection block 3.

[0032] The automatic coating equipment coating needle position confirmation device proposed in this utility model involves a robot controlling the coating needle to hover 3-5cm directly above the XY position positioning cylinder 2. The specific height parameter is set according to the reference height of the center of the Z position positioning detection block 3. The XY position positioning cylinder 2 is manually moved upward along the travel through hole 14 until the bottom of the coating needle can contact the top of the XY position positioning cylinder 2. The device then checks whether the bottom of the coating needle is correctly locked in the center of the tip position hole 21. If the coating needle is against the top plane of the XY position positioning cylinder 2, the XY position of the needle is offset and manual correction is required. After the XY position detection of the coating needle is completed, the XY position positioning cylinder 2 is reset. The Z position positioning detection block 3 is placed on the top of the reset XY position positioning cylinder 2. The through side of the Z position positioning detection block 3 is brought close to the travel through hole 14. The through side of the Z position positioning detection block 3 is controlled to move towards the tip position hole 21. If the coating needle is blocked on the through side of the Z position positioning detection block 3 or the Z position positioning detection block 3 passes through the stop side, the Z position of the needle will be offset. The needle position needs to be manually corrected. This is more accurate than conventional visual confirmation. Moreover, when the position is offset, there is a clear position as a reference for adjustment, which is more efficient.

[0033] The bottom of the aforementioned reference base 1 is a mounting section 11, and the top of the mounting section 11 is provided with a boss connecting ring 12. The boss connecting ring 12 has connecting holes 13 around its perimeter, and bolts are inserted into the connecting holes 13. The reference base 1 has a travel through hole 14 in the center. The mounting section 11 is convenient to be mounted in the through hole of the automatic coating equipment, and the boss connecting ring 12 is convenient to fix the reference base 1 to the automatic coating equipment by bolt connection.

[0034] The aforementioned XY position positioning cylinder 2 is inserted through the center of the reference base 1. The bottom of the XY position positioning cylinder 2 is T-shaped and locked in the travel through hole 14. The XY position positioning cylinder 2 moves up and down along the travel through hole 14. A tip-alignment hole 21 is opened in the center of the top of the XY position positioning cylinder 2. The diameter of the tip-alignment hole 21 is larger than the maximum outer diameter of the needle to be tested. The tip-alignment hole 21 is the reference for XY axis position detection and adjustment of the coating needle. A needle tip clearance hole 22 is opened at the bottom of the XY position positioning cylinder 2. The needle tip clearance hole 22 communicates with the tip-alignment hole 21.

[0035] When the Z position positioning detection block 3 is used for detection, it is placed on top of the XY position positioning cylinder 2. The side of the Z position positioning detection block 3 closest to the pointed position hole 21 is the through side, and the other side is the stop side. The height of the through side is less than the height of the stop side. The difference between the height of the through side and the height of the stop side is 6mm. The standard height of the center of the Z position positioning detection block 3 is an integer such as 3 / 4 / 5. The height difference between the left and right through and stop sides is equivalent to a tolerance of ±0.3.

[0036] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
