Description

Technical Field

[0001] This utility model relates to the field of temperature sensor manufacturing technology, and more specifically, to a laser marking conveyor for temperature sensor housings. Background Technology

[0002] A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. Currently, the most common temperature sensors on the market are resistive temperature sensors and thermocouple temperature sensors. During the production process, the outer wall of the temperature sensor housing needs to be laser-marked.

[0003] A temperature sensor housing is as follows Figure 8 When a worker places product 11 on the marking station of the laser marking equipment, it is difficult for the worker to determine whether the product 11 is placed correctly. If the placement of product 11 is deviated, causing the distance between product 11 and the laser emitter of the laser marking equipment to be outside the predetermined value, the marking quality of product 11 will decrease. Product 11 with poor-quality marking cannot be marked again, making product 11 a defective product, resulting in resource waste and economic loss. At the same time, when the worker uses the laser marking equipment to mark multiple products 11 continuously, the worker needs to frequently place product 11 on the marking station and frequently remove the marked product 11 from the marking station. The worker's labor intensity is high, and the worker's work efficiency will decrease after loading and unloading product 11 for a long time, resulting in an overall decrease in the marking efficiency of product 11. Utility Model Content

[0004] The purpose of this invention is to provide a laser marking conveyor for temperature sensor housings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, one objective of this utility model is to provide a laser marking conveyor for temperature sensor housings, comprising a base, a column fixedly mounted on the top upper surface of the base, a turntable rotatably mounted on the column near its top, and a drive mechanism for driving the turntable to rotate on the column. Eight placement platforms are fixedly connected in a circular array on the upper surface of the turntable. A feeding mechanism, a front-end detection mechanism, a clamping mechanism, a laser marking mechanism, a unloading mechanism, and a rear-end detection mechanism are provided on the upper side of the base. The front-end detection mechanisms are respectively set around the turntable. The feeding mechanism is used to place the product on an adjacent placement platform. The front-end detection mechanism is used to detect whether the product is placed in the predetermined position on the placement platform. After the front-end detection mechanism detects that the product is not in the predetermined position on the placement platform, the clamping mechanism clamps the product and moves the product to the upper side of the placement platform. After the front-end detection mechanism detects that the product is in the predetermined position on the placement platform, the laser marking mechanism performs laser marking on the product. The unloading mechanism removes the marked product from the placement platform. The rear-end detection mechanism is used to detect whether the unloading mechanism removes the product from the placement platform.

[0006] As a further improvement to this technical solution, the drive mechanism includes a servo motor fixedly installed on one side of the column. The servo motor is located on the lower side of the turntable. A drive gear is coaxially fixedly connected to the output shaft of the servo motor. An internal gear is coaxially fixedly connected to the lower surface of the turntable. The internal gear meshes with the drive gear.

[0007] As a further improvement to this technical solution, the feeding mechanism includes a vibrating feeding plate fixedly installed on the upper surface of the base. A vibrating conveyor is fixedly installed on one side of the vibrating feeding plate. A slide rail is opened at the top of the vibrating conveyor, and a low slide groove is opened at the bottom of the slide rail near the turntable. A movable groove through the vibrating conveyor is opened at the bottom of the low slide groove. A progress rod is slidably arranged inside the movable groove. Both ends of the progress rod extend to the outside of the movable groove. A first telescopic rod is fixedly installed at the bottom of the vibrating conveyor. One end of the piston rod of the first telescopic rod is fixedly connected to the lower end of the progress rod. Two first pneumatic grippers are arranged on one side of the vibrating conveyor. The two first pneumatic grippers continuously transfer the products on the vibrating conveyor to the placement table.

[0008] As a further improvement to this technical solution, the front-end detection mechanism includes a second upright frame fixedly installed on the upper surface of the base. A second telescopic rod is fixedly installed on the upper surface of the second upright frame. The lower end of the piston rod of the second telescopic rod passes through the second upright frame and is fixedly connected to an end plate. Three side plates are fixedly connected to the lower surface of the end plate near the edge. A first infrared rangefinder is fixedly installed at the center of the side plates.

[0009] As a further improvement to this technical solution, the clamping mechanism includes a third frame fixedly mounted on the upper surface of the column. A third telescopic rod is fixedly installed on the upper surface of the third frame. The lower end of the piston rod of the third telescopic rod passes through the third frame and is fixedly connected to a second pneumatic gripper. Each of the two grippers of the second pneumatic gripper is fixedly connected to a clamping rod. The two grippers of the second pneumatic gripper respectively drive the two clamping rods to rotate laterally.

[0010] As a further improvement to this technical solution, the laser marking mechanism includes a fourth frame fixedly installed on the upper surface of the column, a fourth telescopic rod fixedly installed on the upper surface of the fourth frame, the lower end of the piston rod of the fourth telescopic rod passing through the fourth frame and fixedly connected to an extension frame, and a laser marking device fixedly installed on the extension frame.

[0011] As a further improvement to this technical solution, the unloading mechanism includes a slide fixedly mounted on the upper surface of the base, the upper end of the slide being located on one side of the turntable, and a third pneumatic gripper being provided on the upper side of the slide.

[0012] As a further improvement to this technical solution, the back-end detection mechanism includes a fifth stand fixedly mounted on the upper surface of the base, a mounting plate fixedly connected to the lower surface of the fifth stand, and a second infrared rangefinder fixedly mounted on the mounting plate. The second infrared rangefinder is located on the side of the placement platform near the axis of the column.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. In this temperature sensor housing laser marking conveyor, when the placement table rotates the product to the position corresponding to the front-end detection mechanism, the front-end detection mechanism will detect the placement position of the product. If the product is not placed in the predetermined position on the placement table, the clamping mechanism will remove the product from the placement table to prevent the product from flowing into the laser marking laser and being marked with poor quality codes, thus making the product defective and improving the product yield.

[0015] 2. This temperature sensor housing laser marking conveyor uses a feeding mechanism to place individual products from a vibrating feeding tray onto a corresponding placement table, achieving automatic product feeding. After the laser marking device completes marking the product, the placement table rotates the product to a position corresponding to the unloading mechanism, which then removes the marked product from the placement table, achieving automatic product unloading. This reduces the labor intensity of workers and improves marking efficiency during the product marking process. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1

[0036] Please see Figures 1-7 As shown, one of the objectives of this embodiment is to provide a laser marking conveyor for a temperature sensor housing, including a base 1. A column 3 is fixedly mounted on the top upper surface of the base 1. A turntable 31 is rotatably mounted on the column 3 near its top. Eight placement platforms 32 are fixedly connected in a circular array on the upper surface of the turntable 31. The upper surface of the placement platforms 32 is used to place products 11. A drive mechanism 4 for driving the turntable 31 to rotate is provided on the column 3. The structure of the drive mechanism 4 is detailed below, referring to... Figure 7 The drive mechanism 4 includes a servo motor 41 fixedly mounted on one side of the column 3. The servo motor 41 is located on the lower side of the turntable 31. A drive gear 42 is coaxially fixedly connected to the output shaft of the servo motor 41. An internal gear 43 is coaxially fixedly connected to the lower surface of the turntable 31. The internal gear 43 meshes with the drive gear 42. The servo motor 41 is electrically connected to an external control device. The control device controls the servo motor 41 to start intermittently. Each time the servo motor 41 starts, the output shaft of the servo motor 41 drives the drive gear 42 to rotate. Through the meshing transmission between the drive gear 42 and the internal gear 43, the internal gear 43 drives the turntable 31 to rotate 45 degrees, so that the next placement table 32 rotates to the position of the previous placement table 32, thereby causing the placement table 32 to drive the product 11 to rotate, so that the turntable 31 completes the feeding effect.

[0037] The upper side of the base 1 is provided with a feeding mechanism 2, a front-end detection mechanism 5, a clamping mechanism 6, a laser marking mechanism 7, a unloading mechanism 8, and a rear-end detection mechanism 9. The feeding mechanism 2, the front-end detection mechanism 5, the clamping mechanism 6, the laser marking mechanism 7, the unloading mechanism 8, and the rear-end detection mechanism 9 are respectively arranged around the turntable 31, and are arranged sequentially around the turntable 31. Four equidistant placement platforms 32 on the turntable 31 correspond to the positions of the feeding mechanism 2, the clamping mechanism 6, the laser marking mechanism 7, and the unloading mechanism 8, respectively. The placement platform 32 between the two placement platforms 32 corresponding to the feeding mechanism 2 and the clamping mechanism 6 corresponds to the front-end detection mechanism 5, and the placement platform 32 between the two placement platforms 32 corresponding to the unloading mechanism 8 and the feeding mechanism 2 corresponds to the rear-end detection mechanism 9.

[0038] The feeding mechanism 2 is used to place the product 11 on an adjacent placement table 32. The structure of the feeding mechanism 2 is described in detail below, please refer to... Figure 2 and Figure 3The feeding mechanism 2 includes a vibrating feeding plate fixedly installed on the upper surface of the base 1. Several products 11 are placed inside the vibrating feeding plate. A vibrating conveyor 21 is fixedly installed on one side of the vibrating feeding plate. A slide rail is provided on the top of the vibrating conveyor 21. After the vibrating feeding plate is started, it conveys the products 11 one by one into the slide rail of the vibrating conveyor 21 by vibration. The products 11 slide along the inner wall of the slide rail towards the turntable 31. A low slide groove 22 is provided at the bottom of the slide rail near the turntable 31. A movable groove 23 penetrating the vibrating conveyor 21 is provided at the bottom of the low slide groove 22. A forwarding rod 24 is slidably installed inside the movable groove 23, with both ends of the forwarding rod 24 extending outside the movable groove 23. The forwarding rod 24 is located in the low slide groove 22. 2. Near one end of the slide, when product 11 falls from one end of the slide into the interior of the low slide trough 22, the advancing rod 24 receives product 11, causing product 11 to be fitted onto the upper end of the advancing rod 24. A first telescopic rod 25 is fixedly installed at the bottom of the vibrating conveyor 21. One end of the piston rod of the first telescopic rod 25 is fixedly connected to the lower end of the advancing rod 24. After product 11 is fitted onto the upper end of the advancing rod 24, the piston rod of the first telescopic rod 25 extends, driving the advancing rod 24 closer to the turntable 31. The moving advancing rod 24 moves product 11 to a predetermined position in the low slide trough 22. At the same time, two first pneumatic grippers 26 are provided on one side of the vibrating conveyor 21. The two first pneumatic grippers 26 continuously transfer the product on the vibrating conveyor 21 to the release plate. On the platform 32, two first pneumatic grippers 26 are fixedly mounted on a sliding plate. A mounting bracket fixed to the base 1 is provided on one side of the sliding plate. The sliding plate slides on the mounting bracket, which is also equipped with a push cylinder. The push cylinder drives the sliding plate to reciprocate on the mounting bracket. A waiting platform is fixed at the midpoint between the vibrating conveyor 21 and the turntable 31. The distance from the waiting platform to the vibrating conveyor 21 or the turntable 31 is the same as the distance between the two first pneumatic grippers 26. When the advance rod 24 moves the product 11 to a predetermined position in the low chute 22, the push cylinder moves the sliding plate away from the turntable 31. At this time, one first pneumatic gripper 26 moves to the upper side of the low chute 22, and the other first pneumatic gripper 26... 6. Move to the waiting table, then the two first pneumatic grippers 26 respectively grip the advancing rod 24 and the product 11 on the waiting table. After the two first pneumatic grippers 26 grip the product 11, push the cylinder to push the slide plate closer to the turntable 31. When the slide plate stops, the first pneumatic grippers 26 holding the product 11 on the advancing rod 24 move to the waiting table, and the first pneumatic grippers 26 holding the product on the waiting table move to the placement table 32. At this time, the two first pneumatic grippers 26 place the product 11 on the waiting table and the placement table 32 respectively. After the two first pneumatic grippers 26 release the product 11, push the cylinder to drive the slide plate to return the two first pneumatic grippers 26 to their original positions. As the slide plate moves away from the turntable 31, the drive mechanism 4 drives the turntable 31 to rotate 45 degrees.The loading mechanism 2 moves the placement table 32, which is not currently holding product 11, to the side closer to the waiting table. Then, the first pneumatic gripper 26 places product 11 onto the placement table 32. This process is repeated to ensure that the loading mechanism 2 continuously places product 11 onto the constantly moving placement table 32.

[0039] The front-end inspection mechanism 5 is used to detect whether the product 11 is placed in the predetermined position on the placement table 32. The structure of the front-end inspection mechanism 5 is described in detail below, please refer to... Figure 4 The front-end detection mechanism 5 includes a second upright 51 fixedly installed on the upper surface of the base 1. A second telescopic rod 52 is fixedly installed on the upper surface of the second upright 51. The lower end of the piston rod of the second telescopic rod 52 passes through the second upright 51 and is fixedly connected to an end plate 53. Three side plates 54 are fixedly connected to the lower surface of the end plate 53 near the edge. A first infrared rangefinder 55 is fixedly installed at the center of the side plate 54. When the turntable 31 drives the eight placement platforms 32 to rotate 45 degrees, one of the placement platforms 32 drives the product 11 to rotate directly below the end plate 53. At this time, the piston rod of the second telescopic rod 52 extends and drives the end plate 53 to move downward until the three side plates 54 respectively drive the three first infrared rangefinders 55 to move to the periphery of the product 11. The first infrared rangefinders 55 emit infrared rays towards the surface of the product 11 and receive the infrared rays reflected from the surface of the product 11 to calculate the distance between the first infrared rangefinder 55 and the product 11. All three infrared rangefinders 55 are electrically connected to an external control device. After the three infrared rangefinders 55 send the calculated distance data to the control device, the control device compares the three sets of data with the pre-saved standard data. The standard data is the distance data between the three infrared rangefinders 55 and the product 11 when the product 11 is placed at the predetermined position on the placement platform 32. If the three sets of data are consistent with the standard data, the control device determines that the product 11 is placed at the predetermined position on the placement platform 32. If the three sets of data are inconsistent with the standard data, the control device determines that the product 11 is not located at the predetermined position on the placement platform 32. At this time, the control device sounds an alarm and sends feedback to the clamping mechanism 6. When the placement platform 32 corresponding to the product 11 moves to the bottom of the clamping mechanism 6, the clamping mechanism 6 unloads the product from the placement platform 32, so that the removed product 11 is put back into the vibrating feeding tray for secondary feeding to avoid resource waste and economic loss.

[0040] After the front-end detection mechanism 5 completes the detection of the position of product 11, the piston rod of the second telescopic rod 52 drives the end plate 53, side plate 54 and first infrared rangefinder 55 to move upward and reset. Then, the turntable 31 drives the eight placement platforms 32 to rotate 45 degrees. One of the placement platforms 32 moves the product 11 to the position corresponding to the clamping mechanism 6. If the front-end detection mechanism 5 detects that the product 11 is not in the predetermined position on the placement platform 32, the clamping mechanism 6 clamps the product 11 and removes the product 11 from the placement platform 32. The structure of the clamping mechanism 6 is detailed below, refer to Figure 4 The clamping mechanism 6 includes a third frame 61 fixedly mounted on the upper surface of the column 3. A third telescopic rod 62 is fixedly mounted on the upper surface of the third frame 61. The lower end of the piston rod of the third telescopic rod 62 passes through the third frame 61 and is fixedly connected to a second pneumatic gripper 63. Each of the two grippers of the second pneumatic gripper 63 is fixedly connected to a clamping rod 64. The two grippers of the second pneumatic gripper 63 drive the two clamping rods 64 to rotate laterally. When the product 11, which is not in the predetermined position, is rotated by the placement table 32 to the position corresponding to the clamping mechanism 6, the piston rod of the third telescopic rod 62 extends, driving the second pneumatic gripper 63 and the two clamping rods 64 to move downwards. Then the second pneumatic gripper... When the two grippers of the movable gripper 63 close, they drive the two clamping rods 64 to move closer together and clamp the product 11. Then, the piston rod of the third telescopic rod 62 retracts, causing the second pneumatic gripper 63 and the two clamping rods 64 to move upward, so that the two clamping rods 64 remove the product 11 from the placement table 32, preventing the product 11 from flowing into the laser marking process. At this time, the turntable 31 continues to rotate to transfer other products 11 without affecting the laser marking mechanism 7 to perform laser marking on other products 11. When the worker hears the alarm and handles the alarm, the product 11 between the two clamping rods 64 is removed, and the clamping function of the two clamping rods 64 on the product 11 is restored.

[0041] When the front-end detection mechanism 5 detects that the product 11 is in the predetermined position on the placement table 32, the clamping mechanism 6 does not move. After the placement table 32 rotates the product 11 to the position corresponding to the laser marking mechanism 7, the laser marking mechanism 7 performs laser marking on the product 11. The structure of the laser marking mechanism 7 is detailed below, refer to... Figure 4 and Figure 6The laser marking mechanism 7 includes a fourth frame 71 fixedly installed on the upper surface of the column 3. A fourth telescopic rod 72 is fixedly installed on the upper surface of the fourth frame 71. The lower end of the piston rod of the fourth telescopic rod 72 passes through the fourth frame 71 and is fixedly connected to an extension frame 73. A laser marking device 74 is fixedly installed on the extension frame 73. When the placement platform 32 rotates the product 11 to the position corresponding to the laser marking mechanism 7, the product 11 is located directly below the laser marking device 74. At this time, the piston rod of the fourth telescopic rod 72 extends, driving the extension frame 73 and the laser marking device 74 to move downward, covering the outside of the product 11 with the laser marking device 74. Then, the laser marking device 74 starts to perform laser marking on the side of the product 11. The laser marking device 74 is a mature device that can be easily purchased on the market, and its working principle will not be described in detail here.

[0042] After the laser marking device 74 completes marking on the side of the product 11, the piston rod of the fourth telescopic rod 72 retracts, causing the extension frame 73 and the laser marking device 74 to move upward and reset. Then, the placement table 32 rotates the product 11 to the position corresponding to the unloading mechanism 8, and the unloading mechanism 8 removes the marked product 11 from the placement table 32. The structure of the unloading mechanism 8 is described in detail below, referring to... Figure 5 The unloading mechanism 8 includes a slide 82 fixedly mounted on the upper surface of the base 1. The upper end of the slide 82 is located on one side of the turntable 31, and the lower end of the slide 82 is provided with a container for collecting the product 11. A third pneumatic gripper 81 is provided on the upper side of the slide 82, and a sliding frame is provided on one side of the third pneumatic gripper 81. A vertical cylinder is mounted on the sliding frame, and the piston rod of the vertical cylinder and the third pneumatic gripper 81 are fixedly mounted together. A support frame is provided on one side of the sliding frame, and the sliding frame is slidably mounted on the support frame. At the same time, a pneumatic push rod is fixed on the support frame, and the pneumatic push rod pushes the sliding frame to slide on the support frame. When the placement table 32 rotates the product 11... When the vertical cylinder moves to the position corresponding to the unloading mechanism 8, it drives the third pneumatic gripper 81 to move downward and clamps and fixes the product 11 during the downward movement of the third pneumatic gripper 81. After the third pneumatic gripper 81 clamps the product 11, the vertical cylinder drives the third pneumatic gripper 81 and the product 11 to move upward. During the upward movement of the product 11, the pneumatic push rod drives the sliding frame to move, so that the third pneumatic gripper 81 moves to the top of the slide 82. Then the third pneumatic gripper 81 releases the product 11, so that the product 11 falls onto the slide 82 under the action of gravity. Then the product 11 slides along the slide 82 into the collection container to complete the unloading.

[0043] After the third pneumatic gripper 81 removes the coded product 11 from the placement table 32, the turntable 31 drives the placement table 32 to rotate 45 degrees, so that the placement table 32 rotates to the position corresponding to the rear detection mechanism 9. The rear detection mechanism 9 is used to detect whether the unloading mechanism 8 has removed the product 11 from the placement table 32. The structure of the rear detection mechanism 9 is described in detail below, refer to Figure 5 The back-end inspection mechanism 9 includes a fifth stand 91 fixedly mounted on the upper surface of the base 1. A mounting plate 92 is fixedly connected to the lower surface of the fifth stand 91. A second infrared rangefinder 93 is fixedly mounted on the mounting plate 92. The second infrared rangefinder 93 is located on the side of the placement platform 32 near the axis of the column 3. Infrared rays emitted by the second infrared rangefinder 93 illuminate the placement platform 32. The second infrared rangefinder 93 is electrically connected to an external control device. When the third pneumatic gripper 81 fails to remove the product 11 from the placement platform 32, the product 11 will rotate with the placement platform 32 to a position corresponding to the back-end inspection mechanism 9. At this time, infrared rays emitted by the second infrared rangefinder 93 will illuminate the product 11, and the second infrared rangefinder 93 will... The distance data between product 11 and the second infrared rangefinder 93 is measured and sent to the control device. This distance data is the error data. When the control device receives the error data, it will issue an alarm and the turntable 31 will stop rotating, reminding the worker to remove product 11 from the placement table 32 to prevent the placement table 32 from rotating back to the position corresponding to the feeding mechanism 2, which would cause interference between the product 11 being fed and the product 11 after coding, affecting the normal operation of the production line. When the second infrared rangefinder 93 does not detect the error data, the turntable 31 will drive the placement table 32 to continue rotating 45 degrees, returning the placement table 32 to the position corresponding to the feeding mechanism 2, so that the placement table 32 completes the conveying work of a single product 11.
