Description

Technical Field

[0001] This application relates to the technical field of laser dot detection equipment, and in particular to a laser dot detection machine. Background Technology

[0002] In the sensor manufacturing process, laser dotting inspection machines are often used to program the sensor chip and to dot the sensor housing with laser dots.

[0003] The laser dotting inspection machine in the related technology includes a base, on which are provided a programming module, a laser dotting module and a transport module. The programming module is used to program the internal chip of the sensor, the laser dotting module is used to perform laser dotting on the sensor shell, and the transport module includes a conveyor belt with a placement seat for placing the sensor. The placement seat is transported sequentially to the corresponding workstation of each module by the conveyor belt to complete the corresponding process.

[0004] When the conveyor belt stops to align the placement base with the programming module or laser dotting module, the placement base and the sensor it carries cannot stop immediately and accurately due to motion inertia. This results in a deviation between the actual stopping position of the placement base and the preset position. The probe or programming head of the programming module is difficult to accurately align with the programming contact of the sensor, which can easily cause poor programming contact or even programming failure, thereby reducing production efficiency and product yield. Summary of the Invention

[0005] To address the problem of difficulty in accurately positioning the placement seat on the conveyor belt, this application provides a laser dotting detection machine.

[0006] This application provides a laser dot detection machine, which adopts the following technical solution: A laser dot detection machine includes a base, on which a transport module and a programming module are mounted. The programming module is used to program a sensor chip. The transport module has a placement seat, which is used to drive the placement seat to move into the programming module. The transport module includes a conveyor belt for moving the placement seat. The base has a positioning mechanism, which includes a blocking structure and a positioning structure. The blocking structure blocks the placement seat on its moving path to achieve initial positioning. The positioning structure includes a positioning moving component and a positioning block. The positioning block is disposed on the positioning moving component. The placement seat has a positioning groove for the positioning block to be inserted into. The positioning moving component drives the positioning block to be inserted into the positioning groove. When the placement seat abuts against the blocking structure, the positioning block can be inserted into the positioning groove.

[0007] By adopting the above technical solution, a blocking structure mechanically obstructs the moving placement seat, achieving reliable initial positioning and stopping the placement seat within a predetermined range. Then, a positioning moving component drives a positioning block to insert into the positioning slot on the placement seat for precise mechanical correction and locking, thereby eliminating the stopping position deviation caused by the conveyor belt stopping and inertia. This ensures that the placement seat stops at the programming station with high precision every time, allowing the programming module's probes or programming head to accurately align with the programming contacts of the sensor chip, effectively avoiding poor programming contact or programming failure, and significantly improving production efficiency and product yield.

[0008] Optionally, the positioning mechanism further includes a lifting structure, which includes a lifting drive and a lifting plate. The lifting drive is mounted on the base, and the lifting plate is mounted on the lifting drive. The blocking structure and the positioning structure are both mounted on the lifting plate. The lifting drive is used to drive the blocking structure and the positioning structure to move away from the placement seat.

[0009] By adopting the above technical solution, after the burning and other processes are completed, the lifting drive can drive the lifting plate to fall as a whole, so that the blocking structure and positioning structure are separated from the movement path of the placement seat, thus not interfering with the normal transmission of the placement seat. This allows the blocking structure and positioning structure to quickly separate from the placement seat. Furthermore, during the process of the lifting structure falling, the blocking structure and positioning structure can be reset so that the blocking structure and positioning structure can accurately position the next placement seat, further improving the automation level and working cycle of the equipment.

[0010] Optionally, the placement base is provided with two mounting slots for placing sensors, and two positioning slots are provided. The blocking structure includes two blocking strips and a blocking drive component. The blocking drive component is used to move one of the blocking strips onto the moving path of the placement base. When each of the blocking strips abuts against the placement base, the positioning block can be inserted into the corresponding positioning slot. When the blocking strip away from the placement base is on the moving path of the placement base, the blocking strip close to the placement base is not on the moving path of the placement base. The conveyor belt is used to drive the placement base to abut against the blocking strip, and the positioning block can be inserted into the corresponding positioning slot.

[0011] By adopting the above technical solution, different blocking bars can be selected to enter the moving path through the blocking drive component, which can correspond to two different workstations of the placement seat. This allows the blocking bars to perform two different initial positioning operations on the same placement seat, so that the subsequent positioning blocks can be inserted into the corresponding positioning slots. This enables the equipment to flexibly adapt to the high-precision positioning requirements of dual-station sensors, and the positioning switching is fast and accurate. This expands the applicable scenarios of the equipment and improves the efficiency of multi-station operations.

[0012] Optionally, the blocking structure further includes a blocking plate with two blocking holes for the blocking strip to pass through. The blocking plate has a rotating cavity connecting the two blocking holes, and a rotating plate is rotatably connected inside the rotating cavity. The drive shaft of the blocking drive is located on the side of the rotating plate away from the blocking strip. The blocking drive is used to drive the rotating plate to rotate inside the rotating cavity. The two blocking strips are located on different sides of the rotating plate. When the rotating plate rotates, one of the blocking strips can be located on the moving path of the placement seat.

[0013] By adopting the above technical solution, the design is ingenious and highly integrated. It can reliably achieve the alternating selection of the two blocking bars with only a single drive source, which simplifies the transmission mechanism, reduces manufacturing costs, and ensures stable and reliable action switching.

[0014] Optionally, the blocking hole extends along a direction perpendicular to the movement of the placement seat, and the blocking strip can abut against different positions of the placement seat when it is in different positions of the blocking hole.

[0015] By adopting the above technical solution, by adjusting the position of the blocking strip in the blocking hole, the blocking strip can abut against different positions of the placement seat, thereby reducing the problem of dents caused by long-term collision between the blocking strip and the placement seat, which affects the positioning accuracy of the initial positioning, so that the subsequent positioning block can stably align with the positioning groove.

[0016] Optionally, the blocking strip includes a first part, a second part, and a third part, with the second part disposed between the first part and the third part, and the first part disposed on the rotating plate. The width of the second part is smaller than the width of the first part and the width of the third part. When the first part or the third part abuts against the wall of the blocking hole, the blocking strip is fixed at the blocking hole. When the second part is located at the blocking hole, the blocking strip can slide along the extension direction of the blocking hole.

[0017] By adopting the above technical solution, when the narrower second part is at the blocking hole, the blocking strip can slide freely along the hole for position adjustment; after adjustment, the wider first or third part can be inserted into the blocking hole, and a stable lock can be achieved using the step. This structure ingeniously achieves tool-free, rapid position adjustment and reliable fixation of the blocking strip, is easy to operate, and has no risk of loosening after locking, ensuring positioning stability for long-term use.

[0018] Optionally, a sliding ramp is provided on the surface of the rotating plate facing the blocking strip, and the distance between the sliding ramp and the ground gradually decreases along the extension direction of the blocking hole; when the second part is located at the blocking hole, the blocking strip abuts against the sliding ramp.

[0019] By adopting the above technical solution, as the rotating plate rotates, the sliding inclined plane smoothly pushes the blocking strip along the extension direction of the blocking hole, automatically completing the precise adjustment of the blocking position. This eliminates the need for manual adjustment or additional drive sources, enabling the position adjustment process to be linked with the workstation switching process and fully automated, further improving efficiency and intelligence.

[0020] Optionally, the base is provided with an adsorption magnet, which is used to adsorb the blocking strip. The adsorption magnet is located on the moving path of the blocking strip driven by the lifting structure. When the lifting structure drives the blocking strip to fall, the adsorption magnet is used to reset the blocking strip.

[0021] By adopting the above technical solution, when the lifting structure falls back to its original position, the adsorption magnet uses magnetic force to attract and fix the blocking strip, which may have deviated from its initial position due to sliding adjustment, back to the preset reference position. This ensures that the subsequent blocking strip still has space to slide in the blocking hole, avoiding the situation where the blocking strip does not have corresponding space in the blocking hole due to long-term sliding along the sliding slope.

[0022] Optionally, the blocking strip has an elastic element on its surface facing the placement seat, the elastic element being used to abut against the placement seat.

[0023] By adopting the above technical solution, the kinetic energy of the placement seat impact is effectively absorbed, reducing the potential damage to the sensor chip and precision structure caused by impact vibration. At the same time, the slight compression of the elastic element can also compensate for the minute gaps between parts, making the positioning contact softer and more snug, further improving the stability of the initial positioning and the reliability of the final accurate positioning.

[0024] In summary, this application includes at least one of the following beneficial technical effects: By mechanically blocking the moving placement seat through a blocking structure, reliable initial positioning is achieved, stopping the placement seat within a predetermined range. Then, a positioning moving component drives a positioning block to insert into the positioning slot on the placement seat for precise mechanical correction and locking, thus eliminating positional deviations caused by conveyor belt stops and inertia. This ensures that the placement seat stops precisely at the programming station each time, allowing the programming module's probes or programming head to accurately align with the programming contacts of the sensor chip, effectively avoiding poor programming contact or programming failures, and significantly improving production efficiency and product yield.

[0025] When the narrower second part is in the blocking hole, the blocking strip can slide freely along the hole for position adjustment; after adjustment, the wider first or third part is inserted into the blocking hole, and a stable lock is achieved using the step. This structure ingeniously achieves tool-free, rapid position adjustment and reliable fixation of the blocking strip, is easy to operate, and has no risk of loosening after locking, ensuring positioning stability for long-term use.

[0028] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail. Example

[0029] This embodiment discloses a laser dot detection machine. (Refer to...) Figure 1 A laser dot-marking inspection machine includes a base 1, on which a transport module 11, a programming module 12, and a laser dot-marking module 13 are mounted. The transport module 11 has a placement seat 2 for placing a sensor. The transport module 11 transports the placement seat 2 to the programming module 12 and the laser dot-marking module 13. The programming module 12 programs the internal chip of the sensor and performs post-programming chip inspection. The laser dot-marking module 13 performs laser dot-marking on the sensor housing.

[0030] Reference Figure 1 and Figure 2The placement base 2 has a mounting slot 22 for placing the sensor. The transport module 11 includes two conveyor belts 111, which extend along the direction from the programming module 12 to the laser dotting module 13, and are used to move the placement base 2 from the programming module 12 to the laser dotting module 13.

[0031] Reference Figure 1 and Figure 2 The base 1 is provided with a positioning mechanism 3, which includes a lifting structure 31, a blocking structure 32 and a positioning structure 33. The blocking structure 32 and the positioning structure 33 are both set on the lifting structure 31. The lifting structure 31 is used to drive the blocking structure 32 and the positioning structure 33 to move in the vertical direction. The blocking structure 32 is used to perform initial positioning of the placement seat 2, and the positioning structure 33 is used to perform fine positioning of the placement seat 2.

[0032] Reference Figure 1 and Figure 2 The lifting structure 31 includes a lifting drive component 311 and a lifting plate 312. In this application, the lifting drive component 311 is a lifting cylinder; in other embodiments, it may be another drive component. The lifting plate 312 is fixedly connected to the drive shaft of the lifting cylinder, which is fixedly connected to the base 1. The lifting cylinder drives the lifting plate 312 to move vertically.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The positioning structure 33 includes a positioning moving component 331 and a positioning block 332. In this application, the positioning moving component 331 is a positioning cylinder; in other embodiments, it may be another driving component. The positioning cylinder is fixedly connected to the lifting plate 312, and the positioning block 332 is fixedly connected to the drive shaft of the positioning cylinder. The positioning cylinder drives the positioning block 332 to move vertically. The placement seat 2 has a positioning groove 21 for the positioning block 332 to be inserted. When the positioning block 332 is inserted into the positioning groove 21, the placement seat 2 can accurately align the probe in the programming module 12 or the mechanical gripper in the laser dotting module 13.

[0034] Reference Figure 2 The blocking structure 32 includes a blocking drive component 321 and a blocking bar 322. In this application, the blocking drive component 321 is a blocking cylinder, which is fixedly connected to the lifting plate 312. The blocking bar 322 is fixedly connected to the drive shaft of the blocking cylinder. The blocking cylinder drives the blocking bar 322 to move vertically.

[0035] Reference Figure 2 and Figure 3The lifting cylinder drives the lifting plate 312 to rise, so that the blocking structure 32 and the positioning structure 33 can be positioned between the two conveyor belts 111. Then, the blocking cylinder drives the blocking strip 322 to extend, so that the blocking strip 322 can initially position the placement seat 2. As the conveyor belt 111 continues to rotate, the placement seat 2 can always abut against the blocking strip 322. Then, the positioning cylinder drives the positioning block 332 to move, so that the positioning block 332 is inserted into the positioning groove 21, thereby achieving precise positioning of the placement seat 2.

[0036] The implementation principle of Example 1 is as follows: by moving the blocking strip 322 and the positioning block 332, the initial positioning and precise positioning of the placement seat 2 are achieved, so that the burning module 12 and the laser dotting module 13 can work smoothly for the sensor. Example

[0037] Reference Figure 4 and Figure 5 The difference between this embodiment and embodiment 1 is that the placement seat 2 has two mounting slots 22, which are arranged in an array along the length of the conveyor belt 111. The placement seat 2 also has two positioning slots 21, which are arranged in an array along the length of the conveyor belt 111.

[0038] Reference Figure 5 and Figure 6 The blocking structure 32 includes a blocking drive member 321, a blocking plate 323, and two blocking strips 322. The blocking plate 323 is fixedly connected to the lifting plate 312. Two blocking holes 34 are formed on the surface of the blocking plate 323 away from the lifting plate 312. The two blocking holes 34 are distributed along the length direction of the conveyor belt 111, and each blocking hole 34 allows the corresponding blocking strip 322 to slide. A rotating cavity 341 is formed on the surface of the blocking plate 323 facing the lifting plate 312, and the rotating cavity 341 connects to the two blocking holes 34.

[0039] Reference Figure 5 and Figure 7 A rotating plate 342 is rotatably connected inside the rotating cavity 341. The length direction of the rotating plate 342 is the same as the length direction of the conveyor belt 111. The blocking strips 322 are located on different sides of the rotating plate 342, and the two blocking strips 322 are located in different blocking holes 34.

[0040] Reference Figure 5 and Figure 6In this application, the blocking drive component 321 is a blocking cylinder, but in other embodiments it may be other drive components. The blocking cylinder is fixedly connected to the lifting plate 312, and the drive shaft of the blocking cylinder is fixedly connected to the side of the rotating plate 342 facing the lifting plate 312. When the blocking cylinder is activated, it drives the rotating plate 342 to swing, allowing the different blocking bars 322 to be smoothly raised and positioned in the moving path of the placement seat 2. When each blocking bar 322 abuts against the placement seat 2, the positioning block 332 is inserted into the corresponding positioning groove 21.

[0041] Reference Figure 5 and Figure 6 When the blocking cylinder is activated, it drives the rotating plate 342 to rotate. The rotating plate 342 swings to make one blocking bar 322 higher than the other blocking bar 322. At this time, the higher blocking bar 322 can be located on the moving path of the placement seat 2, while the lower blocking bar 322 is not on the moving path of the placement seat 2.

[0042] Reference Figure 5 and Figure 6 When the lifting cylinder is activated, it lifts the lifting plate 312. At this time, the blocking strip 322, which is close to the initial position of the conveyor belt 111, is located on the moving path of the placement seat 2. As the conveyor belt 111 moves, the placement seat 2 can abut against the blocking strip 322 to achieve the first preliminary positioning of the placement seat 2. Then, the positioning cylinder lifts the positioning block 332, allowing the positioning block 332 to be inserted into the positioning groove 21, thus achieving the first precise positioning of the placement seat 2.

[0043] The blocking cylinder is activated, causing the rotating plate 342 to rotate. This adjusts the height of the two blocking bars 322, causing the blocking bar 322 closer to the initial position of the conveyor belt 111 to fall down and the blocking bar 322 further away from the initial position of the conveyor belt 111 to rise. This allows the blocking bar 322 closer to the initial position of the conveyor belt 111 to be removed from the moving path of the placement seat 2, while the blocking bar 322 further away from the initial position of the conveyor belt 111 can be positioned on the moving path of the placement seat 2. As the conveyor belt 111 moves, the placement seat 2 can abut against the blocking bars 322 to achieve the second preliminary positioning of the placement seat 2. Afterward, the positioning cylinder drives the positioning block 332 to rise, allowing the positioning block 332 to insert into another positioning slot 21, achieving the second precise positioning of the placement seat 2.

[0044] Then, the lifting cylinder is activated, causing the lifting plate 312 to fall. This allows the positioning block 332 and the blocking strip 322 to simultaneously disengage from the moving path of the placement seat 2. During the falling of the lifting plate 312, the blocking cylinder drives the rotating plate 342 to reset and the positioning cylinder drives the positioning block 332 to reset, so as to facilitate the next lifting and positioning of the lifting plate 312. At the same time, the direct falling of the lifting plate 312 and the synchronous reset of the blocking cylinder and the positioning cylinder further accelerate the release of the fixation of the placement seat 2, allowing the placement seat 2 to move smoothly to the subsequent position.

[0045] Reference Figure 6 and Figure 7 The blocking strip 322 includes a first part 35, a second part 351, and a third part 352. The second part 351 is integrally formed between the first part 35 and the third part 352. The blocking strip 322 is made of iron. The width of the second part 351 is smaller than the width of the first part 35 and the width of the third part 352, and the width of the first part 35 and the width of the third part 352 are the same. The blocking hole 34 extends along the direction from one conveyor belt 111 to another conveyor belt 111. The width of the first part 35 is the same as the width of the blocking hole 34. An elastic member 353 is fixedly connected to the surface of the first part 35 facing the initial position of the conveyor belt 111. The elastic member 353 is used to abut against the surface of the placement seat 2.

[0046] Reference Figure 5 and Figure 7 When the first part 35 or the third part 352 abuts against the wall of the blocking hole 34, the blocking strip 322 can be fixed at the blocking hole 34. When the second part 351 is located at the blocking hole 34, since the width of the second part 351 is smaller than the width of the blocking hole 34, the blocking strip 322 can slide along the length of the blocking hole 34, allowing the blocking strip 322 to abut against different positions of the placement seat 2, thereby reducing the possibility of dents caused by long-term collision between the blocking strip 322 and the placement seat 2 at the same position.

[0047] Reference Figure 7 A sliding inclined surface 343 is formed on the surface of the rotating plate 342 facing the blocking strip 322. The distance between the sliding inclined surface 343 and the ground gradually decreases along the extension direction of the blocking hole 34, and the blocking strip 322 abuts against the sliding inclined surface 343. When the blocking cylinder drives the rotating plate 342 to be parallel to the conveyor belt 111, the rotating plate 342 is in a horizontal state, and the second part 351 of both blocking strips 322 is located at the blocking hole 34. At this time, the blocking strips 322 can slide along the sliding inclined surface 343.

[0048] Reference Figure 7An adsorption magnet 14 is fixedly connected to the base 1. The adsorption magnet 14 extends vertically and is used to adsorb the blocking strip 322. The adsorption magnet 14 can drive the blocking strip 322 to move along the sliding inclined plane 343 to the highest point of the sliding inclined plane 343, thereby realizing the reset of the blocking strip 322.

[0049] Reference Figure 5 and Figure 7 The lifting cylinder drives the lifting plate 312 to fall, and the blocking cylinder drives the rotating plate 342 to reset. During this process, when the rotating plate 342 reaches the horizontal state, the adsorption magnet 14 can adsorb the blocking strip 322, allowing the blocking strip 322 to slide on the sliding inclined surface 343, thereby resetting the blocking strip 322.

[0050] The implementation principle of Example 2 is as follows: the lifting cylinder is activated, and the lifting cylinder drives the lifting plate 312 to rise. At this time, the blocking strip 322 near the initial position of the conveyor belt 111 is located on the moving path of the placement seat 2. As the conveyor belt 111 moves, the placement seat 2 can abut against the blocking strip 322 to achieve the first preliminary positioning of the placement seat 2. Then, the positioning cylinder drives the positioning block 332 to rise, so that the positioning block 332 is inserted into the positioning groove 21 to achieve the first precise positioning of the placement seat 2.

[0051] When the blocking cylinder is activated, it drives the rotating plate 342 to rotate, adjusting the height of the two blocking bars 322. This causes the blocking bar 322 closer to the initial position of the conveyor belt 111 to fall down, while the blocking bar 322 further away from the initial position of the conveyor belt 111 is raised. This allows the blocking bar 322 closer to the initial position of the conveyor belt 111 to be removed from the moving path of the placement seat 2, while the blocking bar 322 further away from the initial position of the conveyor belt 111 is positioned on the moving path of the placement seat 2. At this time, when the rotating plate 342 is in a horizontal state, the blocking bars 322 can slide along the sliding inclined surface 343. As the conveyor belt 111 moves, the placement seat 2 can abut against the blocking bars 322 to achieve the second preliminary positioning of the placement seat 2. Afterward, the positioning cylinder drives the positioning block 332 to rise, allowing the positioning block 332 to insert into another positioning groove 21, achieving the second precise positioning of the placement seat 2.

[0052] Then, the lifting cylinder is activated, causing the lifting plate 312 to fall. This causes the positioning block 332 and the blocking strip 322 to simultaneously disengage from the moving path of the placement seat 2. During the falling of the lifting plate 312, the blocking cylinder causes the rotating plate 342 to reset and the positioning cylinder causes the positioning block 332 to reset, so as to facilitate the next lifting and positioning of the lifting plate 312. At the same time, the direct falling of the lifting plate 312 and the synchronous reset of the blocking cylinder and the positioning cylinder mean that when the rotating plate 342 is in a horizontal state, the adsorption magnet 14 can drive the blocking strip 322 to reset.
