Description

Technical Field

[0001] This invention belongs to the field of bumper manufacturing technology, and specifically relates to a manufacturing process for an illuminated bumper. Background Technology

[0002] With the rapid development of the automotive industry, the front of electric vehicles has undergone significant changes. Exterior designers are incorporating light elements into the design of cars, with exterior lights serving as auxiliary signal lights or as an important component of brand design language. Illuminated bumpers are one such trend. Summary of the Invention

[0003] The main objective of this invention is to provide a manufacturing process for an illuminated bumper, which manufactures the illuminated bumper through an injection molding module, a laser engraving module, a painting module, and a light source installation module, and performs quality inspection at each step to ensure the quality of the finished product. This process has the advantages of high pass rate, high efficiency, and automation.

[0004] To achieve the above objectives, the present invention provides a manufacturing process for an illuminated bumper, comprising the following steps:

[0005] Step S1: The injection molding module uses a pure transparent PP substrate to injection mold the bumper to obtain the first semi-finished product. The first detection unit of the detection module detects the light transmittance of the first semi-finished product to determine whether the light transmittance of the current first semi-finished product meets the preset light transmittance value. If it does, it is transmitted to the laser engraving module through the transmission module. Otherwise, the first semi-finished product is transmitted to the first unqualified area through the transmission module. The pass rate of the injection molding module is obtained by counting the number of first semi-finished products in the first unqualified area.

[0006] Step S2: The first semi-finished product is laser-engraved with micro-features using the laser engraving module. A light-shielding strip is attached to the first semi-finished product and laser-engraved on it to create the desired pattern (so that only the pattern illuminates after the light source is emitted, improving the visibility of the bumper). This results in the second semi-finished product. The second detection unit of the detection module detects the position and integrity of the pattern on the second semi-finished product to determine whether the position and integrity of the current second semi-finished product meet the preset requirements. If they do, the product is transferred to the painting module via the transmission module. Otherwise, the second semi-finished product is transferred to the second non-conforming area via the transmission module. The pass rate of the laser engraving module is obtained by counting the number of second semi-finished products in the second non-conforming area.

[0007] Step S3: The second semi-finished product is sprayed with translucent paint through the coating module to obtain the third semi-finished product. The paint spraying quality of the third semi-finished product is detected by the third detection unit of the detection module to determine whether the paint spraying quality of the current third semi-finished product meets the preset requirements. If it does, it is transmitted to the light source installation module through the transmission module. Otherwise, the third semi-finished product is transmitted to the third unqualified area through the transmission module. The pass rate of the coating module is obtained by counting the number of third semi-finished products in the third unqualified area.

[0008] Step S4: The light source installation module installs the light source on the third semi-finished product to obtain the finished product. The fourth detection unit of the detection module detects the light emission quality of the finished product to determine whether the light emission quality of the current finished product meets the preset requirements. If it does, it is transmitted to the qualified area through the transmission module. Otherwise, the fourth semi-finished product is transmitted to the fourth unqualified area through the transmission module. The pass rate of the light source installation module is obtained by counting the number of finished products in the fourth unqualified area.

[0009] As a further preferred technical solution to the above technical solution, when testing the luminous quality, the light source is lit so that the light emitted by the light source passes sequentially through the transparent first semi-finished product, the hollow pattern carved on the light-shielding strip, and the light-transmitting paint, so that the emitted light presents a pattern shape. The luminous quality of the final product is judged by detecting the matching degree between the presented pattern shape and the carved hollow pattern.

[0010] As a further preferred technical solution to the above technical solution, regarding the matching degree between the pattern shape and the engraved hollow pattern, wherein:

[0011] When the matching degree is greater than the preset value (80%), it is determined that the light emission quality of the current finished product meets the preset requirements and is transmitted to the qualified area;

[0012] When the matching degree is less than the preset value, it is determined that the light emission quality of the current finished product does not meet the preset requirements and is transmitted to the fourth unqualified area.

[0013] As a further preferred technical solution to the above technical solution, the light transmittance preset value is 80%.

[0014] As a further preferred technical solution to the above technical solution, the finished products in the qualified area are automatically packaged by the packaging module. Attached Figure Description

[0018] Preferred embodiment.

[0019] like Figure 1 As shown, this invention discloses a manufacturing process for a light-emitting bumper, including the following steps:

[0020] Step S1: The injection molding module uses a pure transparent PP substrate to injection mold the bumper to obtain the first semi-finished product. The first detection unit of the detection module detects the light transmittance of the first semi-finished product to determine whether the light transmittance of the current first semi-finished product meets the preset light transmittance value. If it does, it is transmitted to the laser engraving module through the transmission module. Otherwise, the first semi-finished product is transmitted to the first unqualified area through the transmission module. The pass rate of the injection molding module is obtained by counting the number of first semi-finished products in the first unqualified area.

[0021] Step S2: The first semi-finished product is laser-engraved with micro-features using the laser engraving module. A light-shielding strip is attached to the first semi-finished product and laser-engraved on it to create the desired pattern (so that only the pattern illuminates after the light source is emitted, improving the visibility of the bumper). This results in the second semi-finished product. The second detection unit of the detection module detects the position and integrity of the pattern on the second semi-finished product to determine whether the position and integrity of the current second semi-finished product meet the preset requirements. If they do, the product is transferred to the painting module via the transmission module. Otherwise, the second semi-finished product is transferred to the second non-conforming area via the transmission module. The pass rate of the laser engraving module is obtained by counting the number of second semi-finished products in the second non-conforming area.

[0022] Step S3: The second semi-finished product is sprayed with translucent paint through the coating module to obtain the third semi-finished product. The paint spraying quality of the third semi-finished product is detected by the third detection unit of the detection module to determine whether the paint spraying quality of the current third semi-finished product meets the preset requirements. If it does, it is transmitted to the light source installation module through the transmission module. Otherwise, the third semi-finished product is transmitted to the third unqualified area through the transmission module. The pass rate of the coating module is obtained by counting the number of third semi-finished products in the third unqualified area.

[0023] Step S4: The light source installation module installs the light source on the third semi-finished product to obtain the finished product. The fourth detection unit of the detection module detects the light emission quality of the finished product to determine whether the light emission quality of the current finished product meets the preset requirements. If it does, it is transmitted to the qualified area through the transmission module. Otherwise, the fourth semi-finished product is transmitted to the fourth unqualified area through the transmission module. The pass rate of the light source installation module is obtained by counting the number of finished products in the fourth unqualified area.

[0024] Specifically, when testing the luminescence quality, the light source is turned on so that the light emitted by the light source passes sequentially through the transparent first semi-finished product, the hollow pattern carved on the light-shielding strip, and the light-transmitting paint, so that the emitted light presents a pattern shape. The luminescence quality of the final product is judged by detecting the matching degree between the presented pattern shape and the carved hollow pattern.

[0025] Furthermore, regarding the matching degree between the pattern shape and the carved openwork pattern, among which:

[0026] When the matching degree is greater than the preset value (80%), it is determined that the light emission quality of the current finished product meets the preset requirements and is transmitted to the qualified area;

[0027] When the matching degree is less than the preset value, it is determined that the light emission quality of the current finished product does not meet the preset requirements and is transmitted to the fourth unqualified area.

[0028] Furthermore, the preset light transmittance is 80%.

[0029] Preferably, the finished products in the qualified areas are automatically packaged by a packaging module.
