Description

Technical Field

[0001] This utility model relates to the technical field of shell drilling equipment, and in particular to a shell drilling equipment for a high-sensitivity heart rate sensor. Background Technology

[0002] In the field of precision electronic component manufacturing, high-sensitivity heart rate sensors are core sensing components for wearable devices such as smartwatches and health monitoring bracelets. The processing precision of their miniaturized housings directly determines the stability of the sensor's signal acquisition and its anti-interference capability.

[0003] When using housing drilling equipment, existing technologies for drilling sensor housings mostly employ a single-station manual clamping mode. Operators need to place the housings one by one, adjust the fixture position, and start the processing unit. Such equipment has significant drawbacks in continuous batch production scenarios: First, a single clamping can only process one housing. After processing, the fixture must be completely released and repositioned, resulting in an excessively high proportion of non-processing time. Second, when manually moving the housing to the next station, relying on visual alignment or simple ruler positioning, accumulated errors can easily cause hole position deviations. Finally, the rigid fixture directly contacts the precision housing surface, and during high-frequency clamping, uneven operating force can easily cause housing deformation or scratches, resulting in large fluctuations in yield.

[0004] Therefore, to address the issue of inconvenient production efficiency in continuous batch production scenarios, a high-sensitivity heart rate sensor housing drilling device can be designed. When using this device, the operator first places the sensor housings to be processed one by one into multiple positioning slots above the sliding seat. Then, multiple clamping seats on both sides are driven to move synchronously towards the housing, thus clamping it together. Once the housing is clamped, the drilling mechanism is activated to perform the drilling operation. After the first housing is drilled, subsequent housings need to be moved sequentially below the drilling mechanism. At this point, the adjustment mechanism is activated, which pushes the sliding seat horizontally via a fixed toothed plate. Through these steps, the sliding seat moves the distance of one positioning slot each time, accurately conveying the next housing to be processed to the bottom of the drilling mechanism. The operator only needs to repeat the "clamping-processing-moving" cycle to achieve continuous batch drilling of multiple housings. In summary, this device, through the design of multi-station positioning slots and distributed clamping seats, achieves batch clamping and synchronous processing of multiple sensor housings, significantly improving production efficiency. It is suitable for small-batch, multi-variety precision processing scenarios such as heart rate sensor housings. Utility Model Content

[0005] To overcome the problem that when using drilling equipment for sensor housings, most drilling equipment adopts a single-station manual clamping mode, which can only process one housing at a time. After processing, the clamp must be completely released and repositioned, resulting in an excessive proportion of non-processing time. Therefore, it is inconvenient to improve production efficiency when used in continuous batch production scenarios.

[0006] The technical solution of this utility model is as follows: a drilling device for processing the housing of a high-sensitivity heart rate sensor, including a drilling frame, a drilling mechanism on the top of the drilling frame, a support base between the bottom of the drilling frame and the drilling mechanism, and a sliding base. A groove is formed on the upper surface of the support base, and the sliding base is slidably embedded in the groove.

Multiple sets of positioning grooves are formed on the upper surface of the sliding base, and the multiple sets of positioning grooves are arranged in a horizontal array. Each set of positioning grooves is arranged between the corresponding clamping seats on both sides. A fixing toothed plate is embedded and fixedly arranged at the bottom of the sliding base.

[0007] Preferably, when using this housing drilling equipment, the operator first places the sensor housings to be processed one by one into the multiple positioning slots above the sliding seat. Then, the multiple clamping seats on both sides are driven to move towards the housing synchronously, thereby clamping the housing together. The flexible layer on the inner wall of the clamping seat can buffer the clamping force and prevent the housing from being damaged due to rigid contact. After the housing is clamped, the drilling mechanism is started to perform drilling operations. After the first housing is drilled, the subsequent housings need to be moved to the bottom of the drilling mechanism in sequence. At this time, the adjustment mechanism is started to push the sliding seat to move horizontally through the fixed toothed plate. Through the above steps, the sliding seat moves the distance of one positioning slot each time, so that the next housing to be processed can be accurately transported to the bottom of the drilling mechanism. The operator only needs to repeat the cycle of "clamping-processing-moving" to realize continuous batch drilling of multiple housings. In summary, this equipment, through the design of multi-station positioning slots and distributed clamping seats, realizes the batch clamping and synchronous processing of multiple sensor housings, which significantly improves production efficiency and is suitable for precision processing scenarios with small batches and multiple varieties, such as heart rate sensor housings.

[0008] Preferably, support plates are symmetrically fixed on both sides of the upper surface of the sliding seat, and an electrically controlled push rod is fixedly installed inside the support plate. A connecting rod is fixedly installed at the telescopic end of the electrically controlled push rod, and the outer wall of multiple clamping seats on one side is fixedly connected to the outer wall of the connecting rod.

[0009] Preferably, two sets of fixing rods are fixedly installed between the two sets of support plates, and sliding blocks are symmetrically fixedly installed on both sides of the connecting rod, with the sliding blocks slidably sleeved on the side wall of the fixing rod.

[0010] Preferably, an adjustment motor is fixedly installed at the bottom of the support base, an adjustment shaft is installed at the output end of the adjustment motor, and an adjustment gear is fixedly installed at the end of the adjustment shaft, the adjustment gear meshing with the fixed gear plate.

[0011] Preferably, guide grooves are symmetrically provided between the bottom of the support base and the groove, and guide rods are fixedly provided inside the guide grooves. Guide blocks are slidably sleeved on the side walls of the guide rods, and the tops of the two sets of guide blocks are fixedly connected to the two sides of the bottom of the sliding base, respectively.

[0012] Preferably, the drilling mechanism includes a C-shaped frame, support rods, a lifting seat, and a hydraulic lifting rod. The C-shaped frame is fixedly installed on the top of the drilling machine frame, and two sets of support rods are fixedly installed inside the C-shaped frame. A lifting seat is installed on one side of the C-shaped frame, and the lifting seat is slidably sleeved on the side wall of the two sets of support rods. A hydraulic lifting rod is fixedly installed on the top of the C-shaped frame.

[0013] Preferably, the drilling mechanism also includes a rotary motor and a drill rod. The telescopic end of the hydraulic lifting rod is fixedly connected to one side of the top of the lifting seat, and a rotary motor is fixedly installed on the other side of the top of the lifting seat. The output end of the rotary motor is equipped with a drill rod.

[0014] The beneficial effects of this utility model are: 1. When using this housing drilling equipment, the operator first places the sensor housings to be processed one by one into the multiple positioning slots above the sliding seat. Then, the multiple clamping seats on both sides are driven to move towards the housing synchronously, thereby clamping the housing together. The flexible layer on the inner wall of the clamping seat can buffer the clamping force and prevent the housing from being damaged due to rigid contact. After the housing is clamped, the drilling mechanism is started to perform drilling operations. After the first housing is drilled, the subsequent housings need to be moved to the bottom of the drilling mechanism in sequence. At this time, the adjustment mechanism is started, which can push the sliding seat to move horizontally through the fixed toothed plate. Through the above steps, the sliding seat moves the distance of one positioning slot each time, so that the next housing to be processed can be accurately transported to the bottom of the drilling mechanism. The operator only needs to repeat the cycle of "clamping-processing-moving" to realize continuous batch drilling of multiple housings. In summary, this equipment, through the design of multi-station positioning slots and distributed clamping seats, realizes the batch clamping and synchronous processing of multiple sensor housings, which significantly improves production efficiency and is suitable for small-batch, multi-variety precision processing scenarios such as heart rate sensor housings.

Firstly, the cooperation between the electrically controlled push rod and the sliding block ensures the stability of the clamping process, and the flexible layer effectively avoids damage to the shell surface, improving the product qualification rate. Secondly, the combination of the adjusting motor and the gear plate mechanism, combined with the auxiliary positioning of the guide rod, realizes the precise stepping movement of the sliding seat, ensuring the repeatability of the drilling position. Overall, the equipment integrates functions such as automated clamping, precise positioning, and continuous processing, improving production efficiency while ensuring processing accuracy and product quality.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figure 1 and Figure 3 This utility model provides an embodiment: a drilling device for processing the housing of a high-sensitivity heart rate sensor, including a drilling frame 1, a drilling mechanism on the top of the drilling frame 1, a support seat 2 between the bottom of the drilling frame 1 and the drilling mechanism, and a sliding seat 3. A groove 4 is formed on the upper surface of the support seat 2, and the sliding seat 3 is slidably disposed inside the groove 4. Multiple sets of clamping seats 5 are symmetrically arranged on both sides of the upper surface of the sliding seat 3, and the multiple sets of clamping seats 5 on both sides are arranged in a one-to-one correspondence. The multiple sets of clamping seats 5 on one side are arranged in a horizontal array. A flexible layer is provided on the inner wall of the clamping seat 5. Multiple sets of positioning grooves 6 are formed on the upper surface of the sliding seat 3, and the multiple sets of positioning grooves 6 are arranged in a horizontal array. Each set of positioning grooves 6 is disposed between the corresponding clamping seats 5 on both sides. A fixing toothed plate 7 is embedded and fixedly disposed at the bottom of the sliding seat 3.

[0019] Please see Figure 3 and Figure 5 Support plates 8 are symmetrically fixed on both sides of the upper surface of the sliding seat 3. An electric push rod 9 is fixedly installed inside the support plate 8. A connecting rod 10 is fixedly installed at the telescopic end of the electric push rod 9. The outer walls of multiple clamping seats 5 on one side are fixedly connected to the outer walls of the connecting rod 10. When the electric push rod 9 in the support plates 8 on both sides is activated, the telescopic end of the electric push rod 9 pushes the connecting rod 10 to move towards the housing. Two sets of fixed rods 11 are fixedly installed between the two sets of support plates 8. Sliding blocks 12 are symmetrically fixed on both sides of the connecting rod 10. The sliding blocks 12 are slidably sleeved on the side walls of the fixed rods 11. Since the two sides of the connecting rod 10 are slidably connected to the fixed rods 11 through the sliding blocks 12, the sliding of the sliding blocks 12 along the fixed rods 11 can effectively limit the movement trajectory of the connecting rod 10, ensuring that it only makes horizontal linear movements and avoiding clamping deviation caused by uneven force on the push rod.

[0020] Please see Figure 4 and Figure 5 An adjusting motor 13 is fixedly installed at the bottom of the support base 2. An adjusting shaft 14 is installed at the output end of the adjusting motor 13. An adjusting gear 15 is fixedly installed at the end of the adjusting shaft 14. The adjusting gear 15 meshes with the fixed toothed plate 7. When the adjusting motor 13 is started, the adjusting gear 15 can be driven to rotate through the adjusting shaft 14. The rotational motion of the adjusting gear 15 is converted into the linear motion of the sliding seat 3, which pushes the sliding seat 3 to move horizontally along the groove 4 on the surface of the support base 2. A guide groove 16 is symmetrically opened between the bottom of the support base 2 and the groove 4. A guide rod 17 is fixedly installed inside the guide groove 16. A guide block 18 is slidably sleeved on the side wall of the guide rod 17. The tops of the two sets of guide blocks 18 are fixedly connected to the bottom sides of the sliding seat 3, respectively. When the adjusting gear 15 rotates, the guide block 18 slides along the guide rod 17, which can effectively counteract the lateral force that may be generated during the movement of the sliding seat 3 and avoid the sliding seat 3 from swaying due to gear meshing clearance or load changes.

[0021] Please see Figure 1 and Figure 2 The drilling mechanism includes a C-shaped frame 19, support rods 20, a lifting seat 21, and a hydraulic lifting rod 22. The C-shaped frame 19 is fixedly installed on the top of the drilling machine frame 1. Two sets of support rods 20 are fixedly installed inside the C-shaped frame 19. The lifting seat 21 is installed on one side of the C-shaped frame 19 and slides on the side wall of the two sets of support rods 20. The hydraulic lifting rod 22 is fixedly installed on the top of the C-shaped frame 19. The telescopic end of the hydraulic lifting rod 22 pushes the lifting seat 21 downward, and the lifting seat 21 descends smoothly along the two sets of support rods 20. The drilling mechanism also includes a rotary motor 23 and a drill rod 24. The telescopic end of the hydraulic lifting rod 22 is fixedly connected to one side of the top of the lifting seat 21. The rotary motor 23 is fixedly installed on the other side of the top of the lifting seat 21. The output end of the rotary motor 23 is equipped with the drill rod 24. When the rotary motor 23 is started, its output end drives the drill rod 24 to rotate at high speed.

[0022] When using this housing drilling equipment, the workflow of the high-sensitivity heart rate sensor housing processing drilling equipment can be divided into four core stages: housing clamping, drilling, sliding seat 3 movement, and batch cyclic processing, as follows: The operator first places the sensor housing to be processed one by one into multiple sets of positioning slots 6 above the sliding seat 3. The positioning slots 6 are arranged in a horizontal array, and each set of positioning slots 6 corresponds to the clamping seats 5 symmetrically arranged on both sides. Through the physical limiting effect of the positioning slots 6, the initial placement position of the housing can be quickly determined to avoid displacement during subsequent clamping.

[0023] Subsequently, the electrically controlled push rods 9 inside the support plates 8 on both sides are activated. The telescopic ends of the electrically controlled push rods 9 synchronously push the connecting rods 10 towards the housing. Since the two sides of the connecting rods 10 are slidably connected to the fixed rods 11 through the sliding blocks 12, the sliding of the sliding blocks 12 along the fixed rods 11 can effectively limit the movement trajectory of the connecting rods 10, ensuring that they only make horizontal linear movements and avoiding clamping deviation caused by uneven force on the push rods. As the connecting rods 10 move, multiple sets of clamping seats 5 on one side of its outer wall are synchronously moved closer to the housing, and finally clamp the housing together with the multiple sets of clamping seats 5 on the other side. The flexible layer set on the inner wall of the clamping seats 5 can buffer the clamping force and prevent the housing from being damaged by rigid contact. At the same time, through the distributed clamping of multiple sets of clamping seats 5, the housing can be stably fixed at multiple points, avoiding housing displacement caused by vibration during drilling.

[0024] After the housing is clamped, the drilling mechanism is started for processing. The C-shaped frame 19 of the drilling mechanism is fixed to the top of the drilling machine frame 1. The two sets of support rods 20 inside provide sliding guides for the lifting seat 21. First, the rotating motor 23 is started, and its output end drives the drill rod 24 to rotate at high speed. At the same time, the telescopic end of the hydraulic lifting rod 22 pushes the lifting seat 21 downward. The lifting seat 21 descends smoothly along the two sets of support rods 20, driving the rotating drill rod 24 to gradually approach the housing. When the end of the drill rod 24 contacts the surface of the housing, the drilling operation begins.

[0025] After drilling is completed, the hydraulic lifting rod 22 retracts in the reverse direction, driving the lifting seat 21 and drill rod 24 to rise to the initial position, completing one drilling action. After the first housing is drilled, the subsequent housings need to be moved to the bottom of the drill rod 24 in sequence. At this time, the adjustment motor 13 at the bottom of the support seat 2 is started. The output end of the adjustment motor 13 drives the adjustment gear 15 to rotate through the adjustment shaft 14. Since the adjustment gear 15 meshes with the fixed tooth plate 7 at the bottom of the sliding seat 3, the rotational motion of the adjustment gear 15 is converted into the linear motion of the sliding seat 3, pushing the sliding seat 3 to move horizontally along the groove 4 on the surface of the support seat 2. To ensure the smooth movement of the sliding seat 3, guide grooves 16 are symmetrically arranged between the support seat 2 and the groove 4. A guide block 18 is slidably sleeved on the guide rod 17 fixed in the guide groove 16. The top of the guide block 18 is fixedly connected to the bottom of the sliding seat 3.

[0026] When the adjusting gear 15 rotates, the guide block 18 slides along the guide rod 17, which can effectively counteract the lateral force that may be generated during the movement of the sliding seat 3, avoid the sliding seat 3 from swaying due to gear meshing clearance or load changes, and ensure the positional accuracy of the housing after each movement {that is, the step distance of each movement is consistent with the distance of the positioning groove 6, ensuring that the drill rod 24 is always aligned with the preset drilling position of the next housing}.

[0027] Through the above steps, the sliding seat 3 moves by the distance of one positioning slot 6 each time {the movement step is determined by the number of teeth and module of the adjusting gear 15}, which can accurately transport the next shell to be processed to the bottom of the drill rod 24. The operator only needs to repeat the cycle of "starting the electric control push rod 9 to clamp - starting the drilling mechanism to process - starting the adjusting motor 13 to move" to realize continuous batch drilling of multiple shells. The equipment has a high degree of automation throughout the process. Only the initial shell needs to be placed manually and each actuator needs to be started, which greatly reduces the time for manual intervention. At the same time, the precise cooperation of the mechanical structure ensures the consistency of processing.

[0028] In summary, firstly, the equipment, through the design of multi-station positioning slots 6 and distributed clamping seats 5, enables batch clamping and synchronous processing of multiple sensor housings, significantly improving production efficiency. Secondly, the cooperation between the electrically controlled push rod 9 and the sliding block 12 ensures the stability of the clamping process, and the flexible layer effectively avoids damage to the housing surface, improving the product qualification rate. Thirdly, the combination of the adjusting motor 13 and the gear tooth plate mechanism, combined with the auxiliary positioning of the guide rod 17, enables the precise stepping movement of the sliding seat 3, ensuring the repeatability of the drilling position. Overall, the equipment integrates functions such as automated clamping, precise positioning, and continuous processing, improving production efficiency while ensuring processing accuracy and product quality. It is suitable for precision processing scenarios involving small batches and multiple varieties, such as heart rate sensor housings.

[0029] Following the steps described above, when using this housing drilling equipment, the operator first places the sensor housings to be processed one by one into the multiple positioning slots 6 above the sliding seat 3. Then, the multiple clamping seats 5 on both sides are driven to move synchronously towards the housing, thus clamping it together. The flexible layer on the inner wall of the clamping seat 5 buffers the clamping force, preventing the housing from being damaged due to rigid contact. After the housing is clamped, the drilling mechanism is started to perform the drilling operation. After the first housing is drilled, subsequent housings need to be moved sequentially below the drilling mechanism. At this time, the adjustment mechanism can be activated by fixing the toothed plate. 7. Push the sliding seat 3 to move horizontally. Through the above steps, the sliding seat 3 moves by the distance of one positioning slot 6 each time, so that the next housing to be processed can be accurately transported to the bottom of the drilling mechanism. The operator only needs to repeat the cycle of "clamping-processing-moving" to realize continuous batch drilling of multiple housings. In summary, the equipment, through the design of multi-station positioning slots 6 and distributed clamping seats 5, realizes the batch clamping and synchronous processing of multiple sensor housings, which significantly improves production efficiency and is suitable for precision processing scenarios with small batches and multiple varieties such as heart rate sensor housings.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
