Description

Technical Field

[0001] The present invention relates to the technical field of lamp holder assembly detection, and in particular to a lamp holder spring processing and detection device and method. Background Art

[0002] The lamp holder is the connecting part between the lamp base and the bulb. The lamp holder assembly requires the installation of a spring sheet. During the installation process, due to the lack of corresponding detection devices, it is easy for the lamp holder pins to be of different lengths or the spring sheet to be missing, resulting in the assembled lamp holder being unable to be used in subsequent processes and also affecting the quality of the final product.

[0003] Chinese patent CN202122893726.0 discloses a pin detection device, including a workbench, a conveyor track, a drive mechanism, a first sensing device, and a second sensing device; the conveyor track is installed on the workbench, the drive mechanism is installed on the conveyor track, and can drive a PCBA board with pins to move on the conveyor track, and the first sensing device and the second sensing device are installed on both sides of the conveyor track to detect the length of the pins on the PCBA board when the PCBA board passes between the first sensing device and the second sensing device.

[0004] The above technical solution can detect whether the pin length is qualified by utilizing whether the component has an obstruction effect on the transmission of the light signal between the sensing devices when the component passes between the first sensing device and the second sensing device; however, there are requirements for the posture of the component. The pin must be completely exposed and unobstructed when passing between the first sensing device and the second sensing device to achieve the purpose of pin length detection. Once the component is placed in an incorrect position, it will affect the final detection result, and it cannot be adapted to the pin detection during the rotation process, so it has limitations.

[0005] The purpose of the present invention is to provide a lamp holder spring processing and testing device and method to solve the above technical problems.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0022] An image acquisition unit, used for acquiring in real time image information of the top of the lamp holder during detection by the pin detection mechanism;

[0023] A processing unit is used to perform hierarchical analysis after comparing pin parameters and image information, and determine whether to generate a marking instruction based on the analysis results;

[0026] As a further technical solution, the processing unit performs a hierarchical analysis process of comparing pin parameters and image information as follows:

[0027] Compare the actual picture information obtained with the standard picture. If they are different, it means that the spring piece is missing and the lamp holder is classified as Class B. If they are the same, it is classified as Class A.

[0028] Get the standard height H of the top surface of the ring under the lamp holder 标 The effective number of pins O, the effective number of pressure sensors R;

[0029] R and R 预 Preset comparison, if R=R 预 , it means that the number of effective pins O all meet the standards and are classified as level 1;

[0030] If R<R 预 , it means that the number of effective pins O does not meet the standard and is classified as level 2;

[0031] The lamp holders are divided into four grades: A1, A2, B1 and B2 based on the comparison of pin parameters and picture information;

[0036] The risk factor P of the current lamp head assembly is compared with the preset threshold P s To compare:

[0037] When P ≥ P s When the lamp head assembly is detected, it is judged that the current lamp head assembly risk is high and the yield rate is low, and an early warning is issued;

[0038] Otherwise, it is determined that the current lamp holder assembly yield rate is good.

[0039] As a further technical solution, a distance sensor is installed on the bottom surface of the ring, and the distance sensor is used to measure the distance between the bottom surface of the ring and the supporting platform.

[0040] A lamp cap spring processing and detection method, the method steps are as follows:

[0041] S1: Prepare the materials and put the lamp head assembly and spring sheet into the No. 1 electromagnetic vibration plate and the No. 2 electromagnetic vibration plate respectively;

[0042] S2: The driving motor drives the turntable to rotate counterclockwise at a constant speed. The No. 1 electromagnetic vibration plate sends the lamp head assembly to the conveyor track, and the first industrial robot picks up the lamp head assembly and puts it into the cylinder.

[0043] S3: When the lamp holder assembly moves to the next station, the second electromagnetic vibration plate sends the spring sheet to the conveyor track, and the second industrial robot installs the spring sheet on the lamp holder assembly to complete the lamp holder spring installation;

[0045] S5: According to the marking information, the third industrial robot takes out the good products from the good product outlet. If they are defective products, they will be taken out. When they reach the defective product outlet, the fourth industrial robot takes out the defective products.

[0046] Beneficial effects of the present invention:

[0047] (1) The lamp holder of the present invention rotates counterclockwise with the turntable and passes through the spring sheet installation, inspection, good product and defective product stations one by one, thereby ensuring that the installation of the pins and spring sheets in the lamp holder assembly is qualified, and the good and defective products are separated and collected at the outlet. At the same time, the pin detection mechanism in the detection equipment is not restricted by obstruction, and only the contact between the pressure sensor and the pin can be used to determine whether the pin is uneven in length, which has few restrictions on use and is more flexible.

[0048] (2) When the ring member in the detection device of the present invention does not move, the upper part of the cylinder is kept open, which facilitates the installation of the lamp holder and the spring sheet. During the detection process, as the ring member moves upward, the traction on the upper baffle is gradually relaxed. Under the elastic force of the torsion spring itself, the upper baffle returns to its initial state, thereby cooperating with and limiting the upper part of the lamp holder, allowing the ring member to move upward to smoothly detect the lamp holder pin, effectively preventing the lamp holder from moving upward due to the push of the bottom ring member, resulting in the pin being unable to be accurately detected.

[0049] (3) The present invention sets a spring piece missing detection module, which can quickly and effectively analyze whether the current lamp holder has a pin length that is too short and a spring piece missing, and comprehensively divides the corresponding level according to the severity of the analysis results. According to the level, it can quickly distinguish whether it is exported from the defective product outlet or the good product outlet, and can also provide direction for the subsequent separate processing of good and defective products. On the one hand, it achieves the purpose of rapid identification, saves the detection time of the lamp holder, and improves the overall efficiency of lamp holder assembly and detection. On the other hand, it can prepare for the subsequent classification of defective and good products. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0058] See also Figure 1-5 As shown, the present invention is a lamp holder spring processing and testing device, comprising a turntable 1, the turntable 1 is rotatably mounted on a base and is in transmission connection with a drive motor, the drive motor is fixed on the base;

[0059] The turntable 1 is provided with a plurality of supporting platforms 2, on which a cylinder 3 with an open top is detachably fixed. The cylinder 3 is used to support the lamp holder, and the cylinder 3 is distributed along the circumference of the turntable 1. The turntable 1 is provided with a first electromagnetic vibration disk 4, a second electromagnetic vibration disk 6, a detection device 5, a defective product outlet 7, and a good product outlet 8 in sequence in a counterclockwise direction.

[0060] Conveying tracks are provided between the No. 1 electromagnetic vibration disk 4, the No. 2 electromagnetic vibration disk 6 and the turntable 1. The No. 1 electromagnetic vibration disk 4 is used to convey the lamp holder assembly to the cylinder, and the No. 2 electromagnetic vibration disk 6 is used to convey the spring sheet to the lamp holder assembly; the detection device 5 is used to detect whether the spring sheet is missing and the pin length of the lamp holder assembly.

[0061] The detection device 5 comprises:

[0062] A pin detection mechanism, used to detect whether the pin is qualified;

[0063] The spring piece missing installation detection module is used to detect whether the spring piece is missing.

[0064] The pin detection mechanism includes:

[0065] A through slot 51 is provided at the bottom of the cylinder 3 and is capable of accommodating a pin at the bottom of the lamp holder;

[0066] A ring 52 is located below the cylinder 3 and matches the through groove 51. A plurality of pressure sensors 53 are provided on the surface of the ring 52. The number of effective working pressure sensors 53 reflects the number of contacts between the ring 52 and the lamp holder pins at the same height.

[0067] A first bevel block 54 , the first bevel block 54 being fixed to the bottom of the ring member 52 with its bevel facing downward;

[0068] A second inclined block 55, wherein the second inclined block 55 is fitted with the inclined surface of the first inclined block 54;

[0069] An electric telescopic rod 56 is installed on a stand 57 , and the stand 57 is fixed on the ground. The telescopic end of the electric telescopic rod 56 is detachably fixed to the second inclined block 55 .

[0070] In this embodiment, the lamp holder and the spring piece are first put into the No. 1 electromagnetic vibration disk 4 and the No. 2 electromagnetic vibration disk 6 respectively, and the driving motor drives the turntable 1 to rotate counterclockwise at a uniform speed. The No. 1 electromagnetic vibration disk 4 sends the lamp holder assembly to the conveying track, and the lamp holder assembly is picked up by the first industrial robot and placed in the cylinder 3. When the lamp holder assembly moves to the next station, the No. 2 electromagnetic vibration disk 6 sends the spring piece to the conveying track, and the second industrial robot installs the spring piece on the lamp holder assembly to complete the installation of the lamp holder spring; when the lamp holder spring is installed and moved to the inspection station, the pin detection mechanism in the inspection device 5 detects the pin, and the spring piece missing detection module detects whether the spring piece is missing, and uses the existing marking equipment to mark it accordingly; according to the marking information, the third industrial robot takes out the good product from the good product outlet 8, and takes out the defective product if it is a defective product. When it reaches the defective product outlet 7, the fourth industrial robot takes out the defective product;

[0071] The lamp holder rotates counterclockwise with the turntable 1 and passes through the spring sheet installation, inspection, good product and defective product stations one by one, thereby ensuring that the pins and spring sheets in the lamp holder assembly are installed properly. The good and defective products are separated at the outlet 7 and collected together. At the same time, the pin detection mechanism in the inspection equipment is not restricted by obstruction. It only needs to determine whether the pins are uneven in length through the contact between the pressure sensor 53 and the pins, which has few restrictions on use and is more flexible.

[0072] The specific working process of the pin detection mechanism is as follows:

[0073] After the lamp holder is equipped with a spring sheet, it continues to move to the detection work. At this time, the turntable 1 stops. Taking advantage of the pause time of the turntable 1, the electric telescopic rod 56 extends and pushes the connected No. 2 inclined block 55 to move toward the supporting platform 2. Since the height of the No. 1 inclined block 54 is lower on the side facing the No. 2 inclined block 55, there is just space for the No. 2 inclined block 55 to enter. As the No. 2 inclined block 55 enters, the No. 1 inclined block 54 and the No. 2 inclined block 55 cooperate to push the No. 1 inclined block 54 upward. The ring 52 on the top of the No. 1 inclined block 54 moves upward and gradually contacts the pin. When the specified height is reached, the pressure sensor 53 contacts the pin at the bottom of the lamp holder and applies pressure to the pressure sensor 53.

[0074] The effective number of the pressure sensor 53 is compared with the number of pins that the lamp holder should have. If the number is less, it means that the pins are too short. The lamp holder with uneven pin lengths is a defective product. The existing marking mechanism is activated to mark the lamp holder in red. If the number is consistent, it means that the pins of the lamp holder meet the requirements and are good products, which can be marked in green.

[0075] If the effective number of pressure sensors 53 increases when the ring 52 reaches the specified height, it means that although the pins meet the composite length requirements, some pins are too long and need to be trimmed. They can be marked in yellow. After the above marking, the subsequent division operation can be facilitated; at the same time, the upward push-up action of the ring 52 can squeeze and bend the pins that exceed the standard length. The bending part is the standard length, and there is no need to measure the pin length separately. In the subsequent trimming, you only need to shorten them along the bending part to achieve the requirement of consistent pin length, which is convenient and quick.

[0076] A plurality of upper baffles 9 are hingedly mounted on the outer wall of the cylinder 3 via torsion springs. A pull rope 10 is provided at the bottom end of the upper baffle 9 . The bottom end of the pull rope 10 passes through the supporting platform 2 and is fixed to the bottom surface of the ring 52 .

[0077] In order to ensure that the lamp holder assembly will not separate from the cylinder 3 during the process of the ring 52 moving up and contacting the pin, an upper baffle 9 is also provided. Under the action of the torsion spring, the upper end of the upper baffle 9 should be in contact with the upper part of the lamp holder to limit the upper part of the lamp holder. However, the ring 52 in the non-working state is at the lowest point. Therefore, the traction of the pull rope 10 acts on the bottom end of the upper baffle 9 to deflect the upper baffle 9. On the one hand, when the ring 52 in the detection device 5 is not in motion, the upper part of the cylinder 3 is kept open to facilitate the installation of the lamp holder and the spring sheet. On the other hand, during the detection process, as the ring 52 moves up, the traction on the upper baffle 9 is gradually relaxed. Under the action of the elastic force of the torsion spring itself, the upper baffle 9 returns to its initial state, thereby cooperating to limit the upper part of the lamp holder, allowing the ring 52 to move up to detect the lamp holder pin smoothly, effectively preventing the lamp holder from moving up due to the push of the bottom ring 52, resulting in the pin being unable to be accurately detected.

[0078] The spring piece missing detection module includes:

[0079] A data acquisition unit, used to collect pin parameters of each lamp holder when it is tested in the pin detection mechanism, wherein the pin parameters include the effective number of pressure sensors, the number of pin contacts and the top surface height of the ring;

[0080] An image acquisition unit, used for acquiring in real time image information of the top of the lamp holder during detection by the pin detection mechanism;

[0081] A processing unit is used to perform hierarchical analysis after comparing pin parameters and image information, and determine whether to generate a marking instruction based on the analysis results;

[0082] The marking unit is used to receive a marking instruction, select a corresponding color mark according to the level of the marking instruction, and mark the current lamp head;

[0083] The early warning unit generates corresponding early warning signals according to the number of marks in a unit of time to remind management personnel.

[0084] In this embodiment, the image acquisition unit and the data information acquisition unit acquire corresponding information, and the processing unit processes the information and classifies the lamp caps according to the processing structure. The marking unit then performs corresponding color marking according to the classification results.

[0085] Through the above information processing process, it is possible to quickly and effectively analyze whether the current lamp holder has a pin length that is too short or a spring piece that is missing, and comprehensively classify the corresponding level according to the severity of the analysis results. According to the level, it is possible to quickly distinguish whether the lamp holder is exported from the defective product outlet 7 or the good product outlet, and it can also provide direction for the subsequent separate processing of good and defective products. On the one hand, it achieves the purpose of rapid identification, saves the inspection time of the lamp holder, and improves the overall efficiency of the lamp holder assembly and inspection. On the other hand, it can prepare for the subsequent classification of defective and good products.

[0086] For example, the severity of pin length being too short, pin length being too long, and missing spring sheets gradually decreases;

[0087] The pin length is too short and the spring piece is missing. Both are classified as defective products. However, the pin length is too short and cannot be used. It is classified as a Class 1 defective product and discarded directly. The pin length is qualified but the spring piece is missing. It is classified as a Class 2 defective product and recycled. You only need to put the lamp head back into the No. 1 electromagnetic vibration plate and reinstall it.

[0088] The spring sheet installation, pin length is too long and the pin length is standard are classified as good products. The pin length is too long, which is classified as good product 2 and can be used but affects the installation, so the pins need to be further trimmed; the pin length is standard, which is classified as good product 1 and can be used directly;

[0089] Through the above division, the lamp holders in the defective and good areas can be further subdivided to improve the utilization rate of the lamp holders, and the pins can be trimmed in a targeted manner to improve the quality of the finished lamp holders;

[0090] The image acquisition unit includes a camera mounted on the stand 57 and aimed at the cylinder above the turntable 1, and uses the camera to take pictures of the top of the lamp head; the marking unit uses existing marking equipment for color marking.

[0091] The hierarchical analysis process of the processing unit for comparing pin parameters and image information is as follows:

[0092] Compare the actual picture information obtained with the standard picture. If they are different, it means that the spring piece is missing and the lamp holder is classified as Class B. If they are the same, it is classified as Class A.

[0093] Get the standard height H of the top surface of the ring under the lamp holder 标 The effective number of pins O, the effective number of pressure sensors R;

[0094] R and R 预 Preset comparison, if R=R 预 , it means that the number of effective pins O all meet the standards and are classified as level 1;

[0095] If R<R 预 , it means that the number of effective pins O does not meet the standard and is classified as level 2;

[0096] The lamp holders are divided into four grades: A1, A2, B1 and B2 based on the comparison of pin parameters and picture information;

[0097] The level information of the current lamp head is sent to the marking unit, and the marking unit marks it according to the color corresponding to the level information.

[0098] In this embodiment, a specific grading method is provided. Specifically, based on the actual image information and the standard image comparison results, it is determined whether the current lamp holder has a missing spring piece. If it is missing, it is divided into area A, and if it is not missing, it is divided into area B. Then, the predetermined height H of the top surface of the ring is determined according to the preset pin length. 标 , obtain the value at the predetermined height H 标 The effective number of pressure sensors R and the preset effective number of pressure sensors R 预 For comparison, if R=R 预 , it means the pin meets the requirements and is classified as level 1. If R<R 预 , it means the pin does not meet the requirements and is classified as level 2;

[0099] After comprehensive analysis, four grades are obtained: A1, A2, B1 and B2, among which B1 is a good product, and A1, A2 and B2 are defective products. A1 can be directly recycled for the lamp holder, B2 can be discarded after recycling the spring sheet, and A2 can be directly discarded. According to the above grade classification, the corresponding processing strategy can be obtained, which can not only realize the rapid detection of the lamp holder assembly status, but also quickly distinguish between good and defective products, and also provide instructions for the subsequent use of defective products, thereby improving the efficiency of defective product classification and processing.

[0100] The process of generating the early warning signal is as follows:

[0101] Get a curve showing the number of A1 grade marks changing over time;

[0102] By formula Calculate the risk factor P of the current lamp assembly, where n is the number of units of time, i∈n, p i is the risk coefficient corresponding to the i-th unit time, S i is the total number of A1-level marks in the i-th unit time, and S0 is the preset standard number interval of A1 level;

[0103] The risk factor P of the current lamp head assembly is compared with the preset threshold P s To compare:

[0104] When P ≥ P s When the lamp head assembly is detected, it is judged that the current lamp head assembly risk is high and the yield rate is low, and an early warning is issued;

[0105] Otherwise, it is determined that the current lamp holder assembly yield rate is good.

[0106] In this embodiment, the number of statistical unit time n, the risk coefficient p corresponding to each unit time i And the total number of A1 level marks per unit time S i To conduct early warning analysis on the status of the current lamp assembly spring, specifically, through the formula Calculate the risk factor P of the current lamp assembly, where n is the number of units of time, i∈n, p i is the risk coefficient corresponding to the i-th unit time, S i is the total number of A1 grade marks in the i-th unit time, S0 is the preset standard number interval of A1 grade, so by counting the number of all A1 grade marks in each unit time, it is possible to combine the number of good lamp holders assembled at present, the number of units in time and the risk coefficients corresponding to different unit times to conduct early warning analysis on the finished lamp holder assembly. By comparing the risk coefficient P of the current lamp holder assembly with the preset threshold value P s By comparing, timely warning and processing of the yield rate of lamp holder assembly can be carried out.

[0107] In the above technical solution, the calculation formula of the risk coefficient P of the current lamp head assembly and the preset threshold value P s It is determined by fitting multiple groups of test data, and the risk coefficient p in different unit time is i It is determined based on the defective product rate per unit time in the history of the equipment. Specifically, the risk factor is 1-10.

[0108] It should also be noted that the early warning analysis process in the above technical solution can be implemented together with the conventional quality control analysis method in the existing technology to achieve the early warning analysis process.

[0109] A distance sensor is mounted on the bottom surface of the ring 52 to measure the distance between the bottom surface of the ring 52 and the support platform 2. In this embodiment, a method for obtaining the height H of the top surface of the ring 52 is provided. The distance sensor obtains the distance between the bottom surface of the ring 52 and the support platform 2 in real time, and then adds the distance to the thickness of the ring 52 to obtain the height H of the top surface of the ring 52.

[0110] A lamp cap spring processing and detection method, the method steps are as follows:

[0111] S1: Prepare the materials and put the lamp head assembly and spring sheet into the No. 1 electromagnetic vibration plate and the No. 2 electromagnetic vibration plate respectively;

[0112] S2: The driving motor drives the turntable to rotate counterclockwise at a constant speed. The No. 1 electromagnetic vibration plate sends the lamp head assembly to the conveyor track, and the first industrial robot picks up the lamp head assembly and puts it into the cylinder.

[0113] S3: When the lamp holder assembly moves to the next station, the second electromagnetic vibration plate sends the spring sheet to the conveyor track, and the second industrial robot installs the spring sheet on the lamp holder assembly to complete the lamp holder spring installation;

[0114] S4: After the lamp holder spring is installed, it is moved to the inspection station. The pin detection mechanism in the inspection device detects the pins. The spring piece missing detection module detects whether the spring piece is missing and uses the marking equipment to mark it accordingly.

[0115] S5: According to the marking information, the third industrial robot takes out the good products from the good product outlet, and takes out the defective products if they are defective products. When they reach the defective product outlet 7, the fourth industrial robot takes out the defective products.

[0116] Working principle of the present invention:

[0117] First, the lamp holder and spring piece are respectively placed into the No. 1 electromagnetic vibration disk 4 and the No. 2 electromagnetic vibration disk 6, and the driving motor drives the turntable 1 to rotate counterclockwise at a uniform speed. The No. 1 electromagnetic vibration disk 4 sends the lamp holder assembly to the conveying track, and the lamp holder assembly is picked up by the first industrial robot and placed in the cylinder 3. When the lamp holder assembly moves to the next station, the No. 2 electromagnetic vibration disk 6 sends the spring piece to the conveying track, and the second industrial robot installs the spring piece on the lamp holder assembly to complete the installation of the lamp holder spring; when the lamp holder spring is installed and moved to the inspection station, the pin detection mechanism in the inspection device 5 detects the pin, and the spring piece missing detection module detects whether the spring piece is missing, and uses the existing marking equipment to mark it accordingly; according to the marking information, the third industrial robot takes out the good product from the good product outlet 8, and takes out the defective product if it is, and waits until it reaches the defective product outlet 7, where the fourth industrial robot takes out the defective product;

[0118] The lamp holder rotates counterclockwise with the turntable 1 and passes through the spring sheet installation, inspection, good product and defective product stations one by one, thereby ensuring that the pins and spring sheets in the lamp holder assembly are installed properly. The good and defective products are separated at the outlet 7 and collected together. At the same time, the pin detection mechanism in the inspection equipment is not restricted by obstruction. It only needs to determine whether the pins are uneven in length through the contact between the pressure sensor 53 and the pins, which has few restrictions on use and is more flexible.

[0119] The specific working process of the pin detection mechanism is as follows:

[0120] After the lamp holder is equipped with a spring sheet, it continues to move to the detection work. At this time, the turntable 1 stops. Taking advantage of the pause time of the turntable 1, the electric telescopic rod 56 extends and pushes the connected No. 2 inclined block 55 to move toward the supporting platform 2. Since the height of the No. 1 inclined block 54 is lower on the side facing the No. 2 inclined block 55, there is just space for the No. 2 inclined block 55 to enter. As the No. 2 inclined block 55 enters, the No. 1 inclined block 54 and the No. 2 inclined block 55 cooperate to push the No. 1 inclined block 54 upward. The ring 52 on the top of the No. 1 inclined block 54 moves upward and gradually contacts the pin. When the specified height is reached, the pressure sensor 53 contacts the pin at the bottom of the lamp holder and applies pressure to the pressure sensor 53.

[0121] The effective number of the pressure sensor 53 is compared with the number of pins that the lamp holder should have. If the number is less, it means that the pins are too short and the lamp holder with uneven pin lengths is a defective product. The existing marking mechanism is activated to mark the lamp holder in red. If the number is consistent, it means that the pins of the lamp holder meet the requirements and are good products, and a green mark is given.

[0122] If the effective number of pressure sensors 53 increases when the ring 52 reaches the specified height, it means that although the pins meet the composite length requirements, some pins are too long and need to be trimmed and marked in yellow. After the above marking, the subsequent division operation can be facilitated; at the same time, the upward push-up action of the ring 52 can squeeze and bend the pins that exceed the standard length, and the bending part is the standard length. There is no need to measure the pin length separately. In the subsequent trimming, you only need to shorten it along the bending part to achieve the requirement of consistent pin length, which is convenient and quick.

[0123] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
