Description

Technical Field

[0001] This invention relates to the field of automated equipment, specifically to an inner and outer shell assembly machine. Background Technology

[0002] With the increasing awareness of health management and the expansion of the diabetic patient population, continuous glucose monitoring (CGM) technology has become a core technology in the field of blood glucose management because it can monitor blood glucose levels in real time and continuously, providing accurate data support for the diagnosis and treatment of diabetes. Its market demand is rapidly increasing.

[0003] Continuous glucose monitoring (CGM), as the core carrier of this technology, is a complex system composed of a variety of precision components, including signal acquisition, processing and transmission, power supply and protection, and fixed auxiliary components. Specifically, it includes a flexible probe integrating working and reference electrodes, a signal conditioning chip, a microcontroller (MCU), a low-power wireless communication module (Bluetooth / NFC), a micro battery, an inner and outer shell, biocompatible adhesive, and auxiliary components such as a temperature compensation sensor, sealing gaskets, and activation switches. All components need to be assembled with high precision to form a complete product in order to realize the functions of continuous acquisition, processing, transmission and accurate monitoring of blood glucose signals.

[0004] In the overall production process of CGM products, the assembly of the inner shell and outer shell is a crucial step connecting the assembly of inner shell components with film encapsulation. It is the final core step in product assembly, and its assembly accuracy and efficiency directly affect the overall performance, production capacity, and manufacturing cost of the product. The inner shell serves as a key carrier for core electronic components such as flexible probes, chips, and batteries, while the outer shell provides protection, fixation, and compatibility with human skin. The assembly of the two must meet strict requirements for coaxiality and fit to avoid damage to internal electronic components due to pressure, abnormal signal transmission, or insufficient sealing performance of the outer shell affecting the product's lifespan due to assembly deviations.

[0005] However, existing technologies for assembling the inner and outer shells of CGM products mostly employ manual or semi-automated assembly methods. Manual assembly relies on the operator's skill and concentration, which is not only labor-intensive and inefficient, making it difficult to meet the production capacity requirements of large-scale production, but also prone to insufficient assembly precision due to factors such as hand tremors and positioning deviations. This can lead to problems such as inner shell tilting, damage to outer shell clips, and poor sealing performance, seriously affecting the product qualification rate.

[0006] In the existing technology, some semi-automated assembly equipment lacks dedicated positioning fixtures, resulting in insufficient positioning accuracy after the inner and outer shells are placed. The lack of a targeted guiding mechanism makes it easy for the inner shell to get stuck or collide when inserted into the outer shell. Furthermore, the coordination between the moving module and the assembly mechanism of the equipment is poor, making it impossible to achieve precise linkage of inner shell clamping, positioning, and insertion, resulting in a difficulty in balancing assembly efficiency and accuracy.

[0007] In addition, the inner and outer shells of CGM products are mostly small and precision structures with small dimensions and strict tolerance requirements. Existing assembly equipment does not fully consider the protection requirements during the assembly process of the inner and outer shells. During the assembly process, improper clamping force or rough insertion method can easily cause scratches on the surface of the outer shell and damage to the internal components of the inner shell, further reducing the product qualification rate.

[0008] Therefore, in response to the technical problems existing in the assembly process of CGM products, such as low automation, insufficient assembly precision, difficulty in meeting the needs of large-scale production, and easy damage to products, there is an urgent need to develop an inner and outer shell assembly machine with a reasonable structure, high automation, high assembly precision, and high efficiency to solve the defects of existing technologies, ensure the assembly quality and production efficiency of CGM products, and meet the surge in market demand for CGM products.

[0026] The following examples further illustrate the features and other related characteristics of the present invention in detail, to facilitate understanding by those skilled in the art: For ease of description and understanding, please refer to the attached diagram for descriptions related to positional relationships such as front, back, top, bottom, left, right, outside, and inside, as well as descriptions related to X, Y, and Z axis directions.

[0027] It should be noted that the inner and outer shell assembly machine in this case includes some common equipment mechanisms or components such as a frame and a protective shell. These are well-known technologies in the field and are not the focus of protection in this case. Therefore, in order to make the description and explanation more intuitive in conjunction with the accompanying drawings, the textual description of this part has been simplified or omitted in this case, and the drawings have also been simplified or omitted.

[0028] The inner and outer shell assembly machine in this case is used to connect the final assembly process of the previous inner shell and the film coating process after the inner and outer shells are assembled. After the film coating is completed, the finished product is packaged.

[0029] like Figures 1 to 5 As shown, this invention provides an inner and outer shell assembly machine, including a frame (not shown in the figure) and an installation platform (not shown in the figure) mounted on the frame. In specific implementation, the frame provides an overall support framework for the device, possessing sufficient rigidity to ensure the stable operation of each mechanism. The installation platform provides an installation support surface for subsequent mechanisms. An XYZ moving module 1 is mounted on the frame, and a clamping assembly mechanism 2 is connected to the XYZ moving module 1. A fixture table 3 is mounted on the installation platform, and the fixture table 3 includes an inner shell positioning groove 31 and an outer shell positioning groove 32. An inner shell 100 is placed in the inner shell positioning groove 31, and an outer shell 200 is placed in the outer shell positioning groove 32. The XYZ moving module 1 in this invention is the power drive component of the clamping assembly mechanism 2, responsible for driving the clamping assembly mechanism 2 to move precisely in three-dimensional space, realizing the full stroke action of clamping the inner shell 100 from the inner shell positioning groove 31, transferring it above the outer shell positioning groove 32, and finally assembling the inner shell 100 into the outer shell 200. The XYZ moving module 1 ensures the accuracy of the moving position and meets the positioning requirements for the precision assembly of the inner and outer shells of CGM products. The three-axis linkage design can fully cover the slot layout on the fixture table 3 and adapt to the spatial position requirements for inner shell clamping and assembly. Users can balance assembly efficiency and smooth operation according to the actual production scenario, and avoid the inner shell 100 from falling off or colliding due to excessive movement during the transfer process.

[0030] The clamping assembly mechanism 2 is suspended below the XYZ moving module 1, receiving the three-dimensional moving power transmitted by the XYZ moving module 1. Its clamping action is linked with the position signal of the XYZ moving module 1, ensuring that the inner shell 100 is gripped and assembled in a precise position. It is the core component connecting the XYZ moving module 1 and the inner shell 100. Driven by the XYZ moving module 1, it completes the assembly action of transferring and inserting the inner shell 100 from the inner shell positioning groove 31 to the outer shell 200. By setting up the clamping assembly mechanism 2, the clamping stability of the inner shell 100 is ensured. The clamping assembly mechanism 2 can penetrate deep into the groove of the fixture table 3 for precise material picking, improving operational flexibility. An inner liner guide mechanism 4 is also installed on the installation platform to guide the inner shell 100 into the outer shell 200. The inner liner guide mechanism 4 can move along the Y-axis direction to insert / remove the outer shell 200 in the outer shell positioning groove 32. By setting up the inner liner guide mechanism 4, the inner shell 100 is inserted into the outer shell positioning groove 32 along the Y-axis direction before the inner shell 100 and outer shell 200 are assembled. This provides precise guidance for the insertion of the inner shell 100, preventing collisions or jamming between the inner shell 100 and the inner wall of the outer shell 200, and ensuring coaxial assembly. The precise fit between the inner liner guide mechanism 4 and the inner wall of the inner shell 100 ensures the coaxiality of the inner shell 100 and outer shell 200 assembly, effectively solving the problems of tilting and misalignment of the inner shell 100 in traditional assembly methods. This facilitates the smooth insertion of the inner shell 100 into the outer shell 200 in the outer shell positioning groove 32, improving equipment operating efficiency and preventing the inner shell 100 from shifting during assembly. In specific implementation, the structural shape of the inner shell positioning groove 31 is adapted to the inner shell 100, and the structural shape of the outer shell positioning groove 32 is adapted to the outer shell 200.

[0031] As described above, in the initial state, the XYZ moving module 1 drives the clamping assembly mechanism 2 to stop at the initial standby position, the inner liner guide mechanism 4 is at the extreme position of Y-axis retraction, the inner shell 100 is placed in the inner shell positioning groove 31 of the fixture table 3, and the outer shell 200 is placed in the outer shell positioning groove 32 (no manual feeding is required, the material is automatically fed by the robot arm in the previous process); after the equipment starts, the inner liner guide mechanism 4 moves forward along the Y-axis direction and inserts the outer shell 200 into the outer shell positioning groove 32 of the fixture table 3. Then, the XYZ moving module 1 moves left and right along the X-axis and forward and backward along the Z-axis, driving the clamping assembly mechanism 2 to precisely move above the inner shell positioning groove 31. Subsequently, the Y-axis descends, aligning the grippers of the clamping assembly mechanism 2 with the inner shell 10, precisely clamping the inner shell 100. Next, the XYZ moving module 1 makes slight adjustments left and right along the X-axis and moves forward and backward along the Z-axis, driving the clamping assembly mechanism 2 holding the inner shell 100 to move above the outer shell positioning groove 32, aligning the axis of the inner shell 100 with the axis of the outer shell 200. After complete alignment, the XYZ moving module 1 drives the Y-axis to continue descending, causing the inner shell 100 to move slowly downwards. Guided by the inner liner guide mechanism 4, the inner shell 100 is smoothly inserted into the outer shell 200 until the inner shell 100 and the outer shell 200 are assembled in place. After assembly, the clamping assembly mechanism 2 releases the inner shell 100, and the XYZ moving module 1 drives the Y-axis to rise, causing the clamping assembly mechanism 2 to rise. Then, it moves left and right along the X-axis and back and forth along the Z-axis to reset to the initial standby position. At the same time, the inner liner guide mechanism 4 resets and removes the outer shell 200 from the fixture table 3. Finally, the robot arm removes the assembled inner and outer shell assembly from the outer shell positioning slot 32. Simultaneously, the front-end robot arm puts the new inner shell 100 and outer shell 200 back into the inner shell positioning slot 31 and the outer shell positioning slot 32, and the equipment enters the next assembly cycle. In this case, through the precise linkage and cooperation of various mechanisms, the efficient and precise automated assembly of the inner shell 100 and outer shell 200 of CGM products is achieved, which greatly improves the assembly efficiency and assembly stability.

[0032] Specifically, refer to Figure 1 , Figure 2As shown, the XYZ moving module 1 of this invention includes a Z-axis moving module 11, an X-axis moving module 12 slidably connected to the Z-axis moving module 11, and a Y-axis moving module 13 slidably connected to the X-axis moving module 12. The clamping assembly mechanism 2 is connected to the Y-axis moving module 13. The XYZ moving module 1 of this invention adopts a three-dimensional three-level sliding connection architecture, ensuring the precision of the movement of the clamping assembly mechanism 2 and improving the assembly accuracy of the inner and outer shells. The three-dimensional motion of the XYZ moving module 1 of this invention is decomposed into three independent and interconnected modules. The Z-axis moving module 11 drives the X-axis, Y-axis, and clamping assembly mechanism 2 to move along the front-back direction; the X-axis moving module 12 drives the Y-axis and clamping assembly mechanism 2 to move along the left-right direction; and the Y-axis moving module 13 independently drives the clamping assembly mechanism 2 to move up and down in the vertical direction. The three modules work together to achieve precise three-dimensional positioning of the clamping assembly mechanism 2. This project simplifies the assembly and debugging process of the XYZ mobile module 1 through its modular mobile module structure. Each axis group can be prefabricated and calibrated independently, improving equipment production efficiency. The three-level sliding connection architecture makes the motion load distribution more reasonable, avoiding the decrease in accuracy caused by excessive load on a single axis group and extending the service life of the equipment. The independent and controllable motion of each axis makes it easy to adjust the motion parameters of a single axis according to assembly requirements, improving the adaptability of the equipment and allowing for adaptive adjustments to different product models.

[0033] Continue to refer to Figure 1 , Figure 2 As shown, further, the Z-axis moving module 11 of this invention includes support frames 111 symmetrically arranged on the left and right sides of the fixture table 3, a first linear module body 112 mounted on the left support frame 111, and a first linear guide rail 113 mounted on the right support frame 111. In specific implementation, the height of the support frames 111 can be adaptively adjusted according to actual product requirements and equipment installation requirements. The support frames 111 provide an equal-height mounting reference for the first linear module body 112 and the first linear guide rail 113, ensuring their parallelism. The first linear module body 112 serves as the Z-axis power source, driving the X-axis moving module 12 to move in the front-back direction. The first linear guide rail 113 provides guiding support for the right end of the X-axis moving module 12, preventing the X-axis moving module 12 from tilting during movement. The symmetrically arranged support frames 111 ensure balanced support force on the Z-axis moving module 11, reducing the impact of frame deformation on motion accuracy. The height-adjustable structure of the support frame 111 allows the equipment to be adapted to jig tables 3 or clamping assembly mechanisms 2 of different heights, expanding the applicability of the equipment. The Z-axis moving module 11 of this invention not only ensures the power output of Z-axis movement but also improves the smoothness of movement, avoiding wobbling caused by sliding of a single guide rail support.

[0034] The X-axis moving module 12 of this invention includes a first connecting frame 121 slidably connected at both ends to a first linear module body 112 and a first linear guide rail 113, and a second linear module body 122 and a second linear guide rail 123 mounted on the first connecting frame 121. The second linear module body 122 and the second linear guide rail 123 are arranged in parallel. The left end of the first connecting frame 121 is slidably connected to the first linear module body 112 via a first slide block 124, and the right end is slidably connected to the first linear guide rail 113 via a first slider 125. The first connecting frame 121 serves as the support for the X-axis, transmitting power from the Z-axis moving module 11 to the second linear module body 122 and the second linear guide rail 123. The second linear module body 122 drives the Y-axis moving module 13 to move in the left-right direction. The second linear guide rail 123 provides guidance for the Y-axis moving module 13. The first slide block 124 and the first slider 125 cooperate to achieve smooth sliding of the first connecting frame 121 along the Z-axis. The dual-rail sliding structure of the second linear module body 122 and the second linear guide rail 123 makes the force on the Y-axis moving module 13 more uniform and improves the stability of the movement.

[0035] The Y-axis moving module 13 of this invention includes a connecting plate 131 slidably connected to both the second linear module body 122 and the second linear guide rail 123, and a third linear module body 132 mounted on the connecting plate 131. The front end of the connecting plate 131 is slidably connected to the second linear guide rail 123 via a second slider 133. The front end of the connecting plate 131 is also slidably connected to the second linear module body 122 via a second slide block 134. The clamping assembly mechanism 2 is slidably connected to the third linear module body 132 via a third slide block 135. The connecting plate 131 transmits X-axis motion power to the third linear module body 132. The third linear module body 132, as the power source of the Y-axis moving module 13, drives the third slide block 135 to move the clamping assembly mechanism 2 up and down, thereby adjusting the height for picking up and assembling the inner shell 100. The second slider 133 and the second slide block 134 respectively cooperate with the second linear guide rail 123 and the second linear module body 122 to slide, ensuring that the connecting plate 131 moves smoothly along the X-axis. At the same time, this symmetrical installation structure makes the connecting plate 131 balanced in the X-axis movement, improving the stability of the Y-axis moving module 13 movement.

[0036] Reference Figures 1-4As shown, preferably, the clamping assembly mechanism 2 of this invention includes a second connecting frame 21, a first cylinder 22 mounted on the second connecting frame 21, and a receiving head 23 mounted on the lower end of the first cylinder 22. A first sensor 24 is mounted on the receiving head 23. The second connecting frame 21 is used for a stable connection with the third slide 135 of the Y-axis moving module 13, and provides mounting support for the first cylinder 22 and the receiving head 23. It works in conjunction with the third linear module body 132 of the Y-axis moving module 13 to achieve precise lifting and lowering of the first cylinder 22 and the receiving head 23, adapting to the material picking and assembly height requirements of the inner shell 100.

[0037] In a specific implementation, the inner shell 100 includes an inner shell body 101, a mounting groove 102 formed on the inner shell body 101, and a strip groove 103 formed on the outer wall of the inner shell body 101. A clamping part 104 is provided in the mounting groove 102, and two strip grooves 103 are symmetrically arranged on the left and right sides.

[0038] Furthermore, the receiving head 23 includes a gripper cylinder 231 connected to the lower end of the first cylinder 22 and a vacuum suction head 232. In a specific implementation, the upper end of the vacuum suction head 232 is connected to an external air extraction device through an air pipe connector 233. In this embodiment, the air extraction device is preferably a vacuum pump.

[0039] The vacuum suction head 232 includes a vacuum nozzle 2321 and elastic pins 2322 symmetrically arranged on both sides of the vacuum nozzle 2321. The elastic pins 2322 are slidably connected to the vacuum nozzle 2321, and their upper ends are connected to a first cylinder 22 to extend and retract relative to the vacuum suction head 232 under the drive of the first cylinder 22, thereby inserting / removing into the strip groove 103. The vacuum suction head 232 is used to adsorb the inner shell body 101, and the gripper cylinder 231 is used to extend into the mounting groove 102 and clamp the clamping part 104.

[0040] As described above, the mounting groove 102 provides insertion space for the gripper cylinder 231 of the receiving head 23, and the clamping part 104 provides a stable clamping position for the clamping action of the gripper cylinder 231, ensuring that the inner shell 100 is reliably clamped. The strip groove 103 is specifically designed to cooperate with the elastic pin 2322 of the receiving head 23 to achieve circumferential positioning of the inner shell 100, preventing circumferential rotation or axial displacement of the inner shell 100 during transfer, and also serving as a foolproof mechanism to prevent the inner shell 100 from being installed backwards. The receiving head 23 of this invention has been adapted to the structure of the inner shell 100 product, ensuring safety and stability during clamping and assembly of the inner shell 100. The structural design of the mounting groove 102 and the clamping part 104 makes the clamping force of the gripper cylinder 231 more concentrated, preventing the inner shell body 101 from being deformed by force. The symmetrical strip grooves 103 and the elastic pins 2322 fit together precisely, effectively restricting the circumferential degree of freedom of the inner shell 100, improving the posture stability during the transfer process, and this foolproof design improves the assembly stability.

[0041] In practical implementation, the gripper opening of the gripper cylinder 231 is adjustable to accommodate different widths of the clamping portion 104 corresponding to different models of inner shells 100. A toothed structure matching the anti-slip texture of the clamping portion 104 is provided on the inner side of the gripper to enhance clamping stability. The vacuum suction head 232 is located below the center of the gripper cylinder 231. The vacuum suction nozzle 2321 is made of silicone, with an arc-shaped end face that fits against the upper end face of the inner shell body 101. An internal air passage connects to the air pipe connector 233 to ensure suction sealing. The elastic pin 2322 is a cylindrical metal component with a nickel-plated anti-rust treatment. A guide chamfer is provided at the lower end for easy insertion into the strip groove 103. The elastic pin 2322 is slidably connected to the vacuum suction nozzle 2321 through a sliding hole, and its upper end is fixed to the piston rod of the first cylinder 22 via a linkage rod, allowing for precise extension and retraction under the drive of the first cylinder 22. The air pipe connector 233 in this case is a quick-connect connector, which is sealed to the air pipe of the external air extraction device to ensure stable negative pressure and continuous and reliable adsorption force. Specifically, the gripper cylinder 231 extends into the mounting groove 102 of the inner shell 100 when picking up materials, and applies clamping force to the clamping part 104 by opening and closing the gripper, thereby achieving mechanical fixation of the inner shell 100. The vacuum suction head 232 generates negative pressure through the external air extraction device, and the vacuum suction nozzle 2321 adsorbs the upper end face of the inner shell body 101, forming a dual fixation of mechanical clamping and vacuum adsorption, further improving the clamping reliability. The elastic pin 2322 extends and retracts under the drive of the first cylinder 22. When inserted into the strip groove 103 of the inner shell 100, it achieves circumferential positioning to prevent the inner shell 100 from rotating or shaking during transfer, and when it is removed, it facilitates the assembly action.

[0042] To maximize production efficiency and adapt to the overall operating efficiency of the equipment, the receiving head 23 and the gripper cylinder 231 are each equipped with at least two sets, and the inner shell positioning groove 31 and the outer shell positioning groove 32 are arranged side by side in two sets. The outer shell positioning groove 32 is located in front of the inner shell positioning groove 31. Of course, users can selectively install different numbers of the above components according to actual production needs and the equipment or product model, and are not limited to this.

[0043] Reference Figure 1 , Figure 2 , Figure 5 As shown, preferably, the inner liner guiding mechanism 4 of this invention includes a fixed bracket 41, a third connecting bracket 43 slidably connected to the fixed bracket 41 via a second cylinder 42, and an inner shell liner mold 44 mounted on the third connecting bracket 43. A second sensor 45 for detecting whether the inner shell liner mold 44 is accurately inserted into the outer shell 200 is also mounted on the third connecting bracket 43. In specific implementation, the inner shell liner mold 44 is hollow inside, and its shape and structure are adapted to the inner and outer shells. It is used to guide the inner shell 100 to be better inserted into the outer shell 200.

[0044] The fixed bracket 41 serves as the supporting foundation for the inner lining guide mechanism 4, and is suspended above the outer shell positioning groove 32. It provides a stable vertical mounting reference for the second cylinder 42 and the third connecting bracket 43, ensuring that the axis of the inner shell lining mold 44 is precisely aligned with the axis of the outer shell 200. The suspension design of the fixed bracket 41 does not affect the loading and unloading of workpieces on the fixture table 3, and provides a stable vertical mounting reference. Its strong structural rigidity can effectively resist the reaction force when the second cylinder 42 is activated, preventing the movement trajectory of the inner shell lining mold 44 from deviating and ensuring guiding accuracy. The second cylinder 42 provides power for the vertical movement (Y-axis direction) of the inner shell liner mold 44, driving it to vertically descend into the outer shell 200 or vertically rise out of the outer shell 200. The thrust of the second cylinder 42 is stable, and the air pressure can be adjusted according to the assembly resistance of the outer shell 200 to avoid impact damage to the inner shell liner mold 44 or the outer shell 200. At the same time, the vertical drive method makes the insertion and removal of the inner shell liner mold 44 smoother and less likely to scratch the inner wall of the outer shell 200. The third connecting bracket 43 achieves a rigid connection between the second cylinder 42 and the inner shell liner mold 44, transmitting the vertical driving force of the second cylinder 42 to the inner shell liner mold 44, and providing a mounting carrier for the second sensor 45, ensuring the synchronous movement of the second sensor 45 and the inner shell liner mold 44. After the inner shell liner mold 44 is vertically inserted into the outer shell 200, it forms a vertical guide channel for the assembly of the inner shell 100, ensuring that the inner shell 100 is vertically inserted into the outer shell 200 along a precise axis and avoiding deviation. The second sensor 45 is used to detect in real time whether the inner shell liner mold 44 is vertically inserted into the outer shell 200 and in place, and feeds back the signal to the control system to ensure the orderly execution of subsequent inner shell 100 assembly actions. The setting of the second sensor 45 realizes the automated detection of the insertion status of the inner shell liner mold 44, avoids assembly deviation of the inner shell 100 due to incomplete insertion, reduces the product defect rate, and forms a closed loop with the control system to improve the automation level of the equipment.

[0045] Furthermore, a third linear guide rail 46 is provided on the fixed bracket 41, and the third connecting bracket 43 is slidably connected to the third linear guide rail 46 via a third slider 49. The upper end of the third connecting bracket 43 is connected to the second cylinder 42 to move under the drive of the second cylinder 42. In specific implementation, two third linear guide rails 46 are arranged side by side to ensure the stability of the movement of the third bracket 43. The sliding cooperation between the third slider 49 and the third linear guide rail 46 provides precise guidance for the up and down movement of the second sensor 45 of the third connecting bracket, limits the horizontal offset of the third connecting bracket 43, ensures that the second sensor 45 of the inner shell liner mold moves up and down along the vertical axis, and at the same time distributes the load to avoid the piston rod of the second cylinder bearing radial force. A hydraulic buffer 47 located at the lower end of the third linear guide rail 46 is also installed on the fixed bracket 41. The hydraulic damper 47 is used to buffer the descent of the third connecting bracket. When the second sensor 4543 of the third connecting bracket descends into position, the hydraulic damper absorbs kinetic energy, slows down the descent speed, avoids damage to the outer shell 200 caused by rigid collision, and ensures the docking accuracy of the two.

[0046] Preferably, continue to refer to Figure 1 , Figure 2 , Figure 5 As shown, the lower end of the fixed bracket 41 is connected to the mounting platform via an adjustable base 48. The adjustable base 48 includes adjusting bolts 481 for adjusting the front-to-back position of the fixed bracket 41 and adjusting bolts for adjusting the left-to-right position of the fixed bracket 41. In this invention, adjusting bolts 481 are used to adjust the positional accuracy of the fixed bracket to correspond to the mounting holes on the mounting platform. Sometimes machining deviations may occur, or different product models may require different tolerances. Adjusting bolts 481 are used to eliminate these deviations, increasing the versatility of the equipment in this invention.

[0047] In this case, the specific structure of the main body of the linear module mentioned is preferably that of a synchronous belt type linear module. The synchronous belt type linear module includes a belt, linear guide rail, metal profile base and housing, coupling, motor, photoelectric sensor, etc. Therefore, other specific structures of the main body of the linear module not mentioned in this case can be implemented by referring to existing synchronous belt type linear modules. Synchronous belt drives have the advantages of high speed, low noise, long stroke, and reliable operation.

[0048] It should be further explained that, in specific implementation, the device in this case also uses multiple inductive switches to detect the presence or absence of objects, and to detect the position or state of objects, thereby triggering the actions of various mechanisms or changing the state of each mechanism, thus realizing the cyclical operation of each mechanism. The relevant content here is well-known technology in the art, and the specific placement and number of each inductive switch will not be described in detail here. In specific implementation, those skilled in the art can adapt the corresponding inductive switches according to common knowledge in the art and the various mechanisms in this case to achieve the linkage between the various mechanisms.

[0049] The following describes the complete working principle of the device in this case, based on the full text: Before the equipment starts, the XYZ moving module 1 drives the clamping assembly mechanism 2 to stop at the initial standby position, and the inner lining guide mechanism 4 is at the extreme position of the Y-axis rise. The inner shell positioning groove 31 and outer shell positioning groove 32 of the fixture table 3 have been automatically placed into the inner shell 100 and outer shell 200 by the robot arm in the previous process. After the equipment starts, the second cylinder 42 of the inner lining guide mechanism 4 drives the third connecting bracket 43 to descend vertically along the double third linear guide rail 46, which drives the hollow contour inner shell lining mold 44 to be smoothly inserted into the inner cavity of the outer shell 200. The hydraulic buffer 47 buffers the descent impact, and the second sensor 45 detects that the mold has been inserted into place and feeds back a signal to the control system. Subsequently, the Z-axis moving module 11 and X-axis moving module 12 of the XYZ moving module 1 work together to drive the clamping assembly mechanism 2 to move above the inner shell positioning groove 31. The Y-axis moving module 13 drives the clamping assembly mechanism 2 to descend, and the first sensor 24 detects the inner shell lining mold. After shell 100 is in place, vacuum suction head 2321 adsorbs inner shell body 101, gripper cylinder 231 extends into mounting groove 102 to clamp gripping part 104, first cylinder 22 drives elastic pin 2322 to insert into strip groove 103 to complete circumferential positioning; then XYZ moving module 1 drives clamping assembly mechanism 2 holding inner shell 100 to move above outer shell positioning groove 32, fine adjustment to make the axis of inner shell 100 coincide with the axis of inner shell liner mold 44, Y-axis moving module 13 drives inner shell 100 to smoothly insert into outer shell 200 along mold guide channel; after assembly is in place, clamping assembly mechanism 2 releases inner shell 100 and resets, inner liner guide mechanism 4 rises synchronously to remove outer shell 200, finally the robot arm takes out the assembled inner and outer shell assembly, and at the same time the new inner shell 100 and outer shell 200 are sent into the corresponding positioning groove, the equipment enters the next cycle, realizing efficient and precise automated assembly of inner and outer shells of CGM products.

[0050] As stated above, this case protects an internal and external assembly machine, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
