Description

Technical Field

[0001] This invention relates to the field of air switch assembly equipment, and in particular to an automatic assembly equipment for air switch windows. Background Technology

[0002] An air switch, also known as an air circuit breaker, is a type of circuit breaker that automatically disconnects the circuit when the current exceeds the rated current. Air switches are crucial electrical appliances in low-voltage power distribution networks and electric drive systems, integrating control and multiple protection functions, and are frequently used in typical household wiring. This application relates to the assembly equipment for the plastic housing of air switches and related components.

[0003] The plastic housing of the air switch consists of two interlocking upper and lower housings. The lower housing has a viewing window for observing the internal components of the air switch. A transparent plastic sheet, also called a "window," is installed inside this viewing window. This window facilitates observation of the air switch's internal components while preventing external impurities from entering. Because the window is very small and is installed in a slot on the inner wall of the lower housing, it requires manual installation. During installation, the upper and lower housings are first separated, and then the window is inserted into the slot. Manual assembly is cumbersome, has poor positioning accuracy, a low yield rate, low work efficiency, and is not conducive to large-scale production. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide an automatic assembly equipment for air switch windows, which solves the problems of cumbersome manual assembly operation, poor positioning accuracy, low yield, low work efficiency, and unfavorable conditions for large-scale production in the prior art.

[0005] To achieve the above and other related objectives, the present invention provides an automatic assembly device for an air switch window. The plastic housing of the air switch includes an upper housing, a lower housing, and a window, wherein the window is installed in a slot at the viewing hole of the lower housing; comprising:

[0006] The workbench is equipped with a platform for positioning and mounting multiple of the plastic housings.

[0007] An automatic plastic shell feeding device is located at the front end of the platform on the workbench and is used to feed a batch of plastic shells onto the platform.

[0008] An automatic feeding and transfer device for viewing windows is located on one side of the platform on the workbench. It is used for automatic batch feeding of viewing windows and to transfer multiple viewing windows to the top of the platform.

[0009] An automatic window installation device is located behind the stage on the workbench and is used to simultaneously insert multiple window pieces into the slots at the viewing holes of the lower housing.

[0010] An automatic plastic shell unloading and sorting device is located below the platform and is used to transfer assembled plastic shells in batches to the sorting area on the platform and remove defective products.

[0011] The detection device, installed on the workbench, is used to detect defective products.

[0012] The controller is used to control the above-mentioned execution units to operate according to a predetermined rhythm.

[0013] In the above design, the automatic feeding device for the plastic shell and the automatic feeding and transfer device for the viewing window are used to realize the automatic batch feeding of the plastic shell and the viewing window, respectively; the automatic installation device for the viewing window is used to simultaneously insert multiple viewing windows into the slots at the viewing holes of the lower shell; and the automatic unloading and sorting device for the plastic shell, together with the detection device and the controller, realizes the rejection of defective products and the collection of good products.

[0014] Preferably, the automatic feeding and transfer device for the viewing window includes a vibratory feeder, a transfer and pushing mechanism, an equidistant differential mechanism, and a transfer mechanism. The transfer and pushing mechanism includes a pushing component and a material trough plate. The material trough plate has multiple through slots for accommodating the viewing window. The pushing component includes multiple inserts that can be movably inserted into the through slots, and the inserts can push the viewing window out from the other end of the through slots. The equidistant differential mechanism includes a group of material separating plates. The group of material separating plates includes multiple parallel material separating plates. Each material separating plate has a material separating slot for receiving the viewing window on the side closest to the material trough plate. The vibratory feeder guides multiple viewing windows into the multiple through slots of the material trough plate through a vibration transmission track. The pushing component cooperates with the material trough plate to guide multiple viewing windows into the material separating slots of the multiple material separating plates for the transfer mechanism to use. The transfer mechanism transfers the viewing window to the top of the platform.

[0015] In the above design, the vibratory feeder is responsible for arranging the randomly placed materials (window pieces) one by one and then transferring them to the transfer and pushing mechanism via the vibratory transmission track; the material trough plate of the transfer and pushing mechanism is responsible for docking with the vibratory transmission track to guide the window pieces into the through slot; the pushing component uses its multiple inserts to push multiple window pieces out of the through slot and into the material distribution slot of the equidistant differential mechanism for use by the window piece transfer device; through the coordinated operation of the vibratory feeder, the transfer and pushing mechanism and the equidistant differential mechanism, the batch automatic feeding of window pieces is realized, which greatly improves the automation level of the automatic assembly equipment for air switch window pieces.

[0016] Preferably, the equidistant differential mechanism further includes a sliding guide frame and a differential assembly, wherein the material distribution plate is slidably connected to the sliding guide frame, and each material distribution plate has a fixed terminal and a sliding terminal at its lower end; the differential assembly includes multiple independent differential plates, each differential plate having a fixed connection end and a sliding limiting groove; two adjacent material distribution plates are connected through a differential plate, wherein the fixed terminal is slidably connected to the sliding limiting groove of the differential plate, and the fixed terminal is fixedly connected to the fixed connection end of the differential plate.

[0017] In the above design, the multiple differential plates that make up the differential component have the same structure, and the multiple material distribution plates cooperate with the differential component, making it easy to merge and separate the multiple material distribution plates at equal intervals.

[0018] Preferably, the transfer mechanism includes a frame, a vertical transfer plate, and a horizontal transfer plate. The vertical transfer plate is slidably connected to the frame via a Y-axis drive mechanism, and the horizontal transfer plate is slidably connected to the vertical transfer plate via an X-axis drive mechanism. A mounting plate is fixedly connected to the horizontal transfer plate, and multiple negative pressure suction heads are rotatably mounted on the mounting plate. The negative pressure suction heads adsorb the viewing window in the dispensing trough. The mounting plate is provided with an attitude adjustment component for driving the negative pressure suction heads to rotate to adjust the attitude of the viewing window.

[0019] In the above design, the vertical transfer plate moves up and down relative to the frame under the drive of the Y-axis drive mechanism, aligning multiple negative pressure suction heads with multiple windows on the automatic window loading device. After the negative pressure suction head picks up the window, it rotates axially under the action of the posture adjustment component, so that the orientation of the window adapts to the installation requirements of the next station (window installation station). After the posture adjustment is completed, the horizontal transfer plate moves horizontally under the drive of the X-axis drive mechanism, synchronously transporting multiple windows to the window installation station for the next installation process. Through the cooperation of the vertical transfer plate, horizontal transfer plate, X-axis drive mechanism, Y-axis drive mechanism, negative pressure suction head and posture adjustment component, the batch automatic transfer and posture adjustment of windows between different stations are realized, which greatly improves the automation level of the automatic assembly equipment for air switch windows.

[0020] Preferably, the detection device employs a visual recognition component, which is positioned along the transport path of the viewing window, enabling the orientation of all viewing windows to be detected by the visual recognition component, which then feeds back the detection results to the controller.

[0021] In the above design, during the detection process, the visual recognition component will feed back the location number of the defective product to the controller. The controller will then control the automatic plastic shell unloading and sorting device to remove the defective product, thereby achieving automatic sorting. Furthermore, the visual recognition component will identify two situations: the negative pressure suction head not adsorbing the viewing window and the viewing window being in an incorrect posture. Both of these situations indicate that the viewing window cannot be correctly installed in subsequent operations, thus resulting in defective products.

[0022] Preferably, the automatic plastic shell feeding device includes a feeding platform, multiple storage mechanisms, and a pushing mechanism; wherein, the multiple storage mechanisms are linearly arranged and fixedly installed on the feeding platform, and multiple plastic shells are vertically stacked in each storage mechanism; the carrying platform is located on one side of the discharge port of the storage mechanism, and the carrying platform is provided with multiple mounting positions corresponding one-to-one with the discharge port of the storage mechanism; the pushing mechanism is slidably installed on the feeding platform, located on the opposite side of the discharge port of the storage mechanism; the pushing mechanism includes multiple push plates, which are respectively arranged corresponding to the multiple storage mechanisms, and the pushing mechanism, driven by the driving device, uses the multiple push plates to synchronously push the plastic shells located at the bottom of the multiple storage mechanisms to the multiple mounting positions on the carrying platform, thereby completing the batch feeding operation of the plastic shells.

[0023] In the above design, the operator pre-places a batch of plastic shells into the multiple storage mechanisms. When the automatic plastic shell feeding device is working, the pushing mechanism operates periodically under the drive of the drive device, using multiple push plates to simultaneously push the plastic shells located at the bottom of the multiple storage mechanisms to multiple mounting positions on the platform. The pushing mechanism completes the feeding operation of the plastic shells before each working cycle of the automatic window assembly device, realizing the automation of batch feeding of plastic shells.

[0024] Preferably, the automatic installation device for the viewing window includes an opening mechanism and an installation mechanism; wherein, the installation mechanism is disposed on one side of the platform and includes a second bracket, a spatial position adjustment component, a positioning guide component, and a connector for finally completing the installation action; the second bracket is fixedly connected to the worktable, and the connector is connected to the second bracket through the spatial position adjustment component; the spatial position adjustment component drives the connector to adjust its spatial position to align with the positioning guide component; the opening mechanism includes a third bracket and a gripping component; the third bracket is fixedly installed on the worktable, and the gripping component is slidably connected to the third bracket through a first lifting mechanism; the gripping component grips the upper shell of the plastic shell and lifts it to a height that does not interfere with the transfer mechanism for transporting the viewing window.

[0025] In the above design, multiple plastic shells are sequentially installed on the mounting positions of the stage. The gripping component of the opening mechanism separates the upper and lower shells of the plastic shells, exposing the slots. The insertion part is aligned with the slots by the spatial position adjustment component, and the viewing window is pushed into the slots with the assistance of the positioning guide component. Through the coordinated operation of the stage, the opening mechanism, and the installation mechanism, the automated installation of the viewing window is achieved, improving the installation efficiency of the viewing window.

[0026] Preferably, the automatic plastic shell unloading and sorting device includes: a platform, a conveying mechanism, and a sorting mechanism; wherein, the platform is mounted on the upper surface of the workbench at both ends via first supports, and the platform is rotatably connected to the first supports via a rotary drive device; multiple assembled plastic shells are placed on the platform; the conveying mechanism is located below the platform and includes a first conveying trough and a pusher mechanism; the sorting mechanism includes a pusher mechanism located on the upper surface of the workbench and multiple rejection components located on the lower surface of the workbench, with the multiple rejection components corresponding one-to-one with the multiple plastic shells; the platform is flipped towards the side closer to the first conveying trough under the drive of the rotary drive device, guiding the multiple plastic shells into the first conveying trough; the multiple plastic shells move towards the sorting mechanism under the pusher mechanism; the rejection components reject defective products according to the feedback from the detection device and guide them into a defective product recycling bin.

[0027] In the above design, the platform is flipped towards the side closer to the first transmission groove under the drive of the rotary drive device, and the multiple plastic shells are introduced into the first transmission groove. The multiple plastic shells are moved towards the sorting mechanism under the pusher mechanism, and the plastic shells with missing viewing windows are introduced into the defective product recycling bin below the workbench under the action of the multiple rejection components. The batch unloading and sorting of plastic shells are realized through the cooperation of the platform, the transmission mechanism and the sorting mechanism, which greatly improves the automation and efficiency of unloading.

[0028] Preferably, the rejection assembly includes a support block for supporting the plastic shell and a third linear drive device for driving the support block to extend and retract, the third linear drive device being electrically connected to the controller; a rectangular trough is provided on the worktable, the support block extends and retracts in the rectangular trough along the width direction of the rectangular trough, and the defective product recycling box is located directly below the rectangular trough.

[0029] In the above design, after receiving feedback from the detection device, the controller controls the corresponding rejection component to operate, causing the corresponding plastic shell to leak out of the rectangular trough and fall into the defective product recycling bin below, while good products remain on the workbench surface; through the cooperation of the detection device, the controller, and multiple rejection components, the effect of automatically rejecting defective products (plastic shells without correctly installed viewing windows) is achieved.

[0030] Preferably, the pushing mechanism includes a pusher plate and a second linear drive device. The sorting area on the workbench is provided with a good product storage area. Under the drive of the second linear drive device, the pusher plate pushes the assembled plastic shell to the good product storage area for temporary storage.

[0031] As described above, the automatic assembly equipment for air switch windows of the present invention has the following beneficial effects: The automatic feeding device for the plastic housing and the automatic feeding and transfer device for the window pieces respectively realize the automatic batch feeding of the plastic housing and the window pieces; the automatic installation device for the window pieces synchronously inserts multiple window pieces into the slots at the viewing holes of the lower housing; the automatic unloading and sorting device for the plastic housing, along with the detection device and controller, achieves the rejection of defective products and the collection of good products; the present invention fully realizes the automatic assembly of air switch windows, greatly improving the assembly efficiency of the window pieces and adapting to large-scale production. Simultaneously, the real-time monitoring of the assembly operation through a visual recognition component greatly improves the yield rate. Attached Figure Description

[0071] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0072] Please see Figures 1 to 32 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and to facilitate understanding and reading. They are not intended to limit the scope of the invention and therefore have no substantial technical significance.

Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0073] Please see Figures 1-4 This invention provides an automatic assembly device for air switch windows, used for automatically assembling air switch windows. The plastic housing 1 of the air switch includes an upper housing 2, a lower housing 3, and a window 4. The window 4 is installed in a slot 6 at the viewing hole 5 of the lower housing 3. The automatic assembly device for air switch windows includes:

[0074] Workbench 7, with a platform 8 for positioning and mounting six plastic housings 1:

[0075] The automatic plastic shell feeding device 9 is located at the front end of the loading platform 8 on the workbench 7, and is used to feed a batch of plastic shells 1 onto the loading platform 8.

[0076] The automatic loading and transfer device 10 for viewing windows is located on one side of the loading platform 8 on the worktable 7. It is used for automatic batch loading of viewing windows 4 and to transfer six viewing windows 4 to the loading platform 8.

[0077] The automatic window installation device 11 is located behind the loading platform 8 on the worktable 7, and is used to simultaneously insert the six windows 4 into the slots 6 at the viewing holes 5 of the lower housing 3.

[0078] An automatic plastic casing unloading and sorting device 12 is located below the platform 8. It is used to transfer assembled plastic casings 1 in batches to the sorting area on the workbench 7 and reject defective products. Furthermore, a defective product recycling bin 101 for storing defective products is provided below the workbench 7.

[0079] The detection device 13 is installed on the workbench 7 and is used to detect defective products.

[0080] The controller (not shown in the figure) is used to control the actions of the above-mentioned execution units according to a predetermined rhythm.

[0081] In this design, the automatic batch feeding of plastic shells 1 and window pieces 4 is achieved through the automatic plastic shell feeding device 9 and the automatic window piece feeding and transfer device 10, respectively. The automatic window piece installation device 11 simultaneously inserts six window pieces 4 into the slots 6 at the viewing holes 5 of the lower housing 3. The automatic plastic shell unloading and sorting device 12, the detection device 13, and the controller work together to remove defective products and collect good products.

[0082] Furthermore, the workbench is fixedly installed on the protective frame 129, and a protective plate 130 is fixedly installed on the protective frame.

[0083] 1. Automatic film loading and transfer device (see also) Figure 5-12 )

[0084] Please see Figures 5-12 In this embodiment, the automatic feeding and transfer device 10 for the window film includes a vibratory feeder 14, a transfer and pushing mechanism 15, an equidistant differential mechanism 16, and a transfer mechanism.

[0085] The transfer and pushing mechanism 15 includes a pushing component 17 and a material trough plate 18. The material trough plate 18 has six through slots 19 for accommodating the viewing window 4. The pushing component 17 includes six inserts A20 that are movably inserted into the through slots 19. The inserts A20 can push the viewing window 4 out from the other end of the through slot 19.

[0086] The equidistant differential mechanism 16 includes a material distribution plate group 21, which includes six parallel material distribution plates 22. Each material distribution plate 22 has a material distribution slot 23 for receiving the viewing window 4 on the side near the material trough plate 18.

[0087] The vibratory feeder 14 guides the six viewing windows 4 into the six through slots 19 of the material trough plate 18 via the vibration transmission track 24. The pushing assembly 17, in cooperation with the material trough plate 18, guides the six viewing windows 4 into the distribution slots 23 of the six distribution plates 22 for use by the transfer mechanism. The transfer mechanism then transports the viewing windows 4 to the top of the loading platform 8.

[0088] In the above scheme, the vibratory feeder 14 is responsible for arranging the randomly placed materials (window pieces 4) one by one and then transferring them to the transfer and pushing mechanism 15 via the vibratory transmission track 24. The material trough plate 18 of the transfer and pushing mechanism 15 is responsible for docking with the vibratory transmission track 24 to guide the window pieces 4 into the through slot 19. The pushing assembly 17 uses its six inserts A20 to push the six window pieces 4 out of the through slot 19 and into the material distribution slot 23 of the equidistant differential mechanism 16 for use by the transfer mechanism 40. Through the coordinated operation of the vibratory feeder 14, the transfer and pushing mechanism 15 and the equidistant differential mechanism 16, the batch automatic feeding of the window pieces 4 is realized, which greatly improves the automation level of the automatic assembly equipment for air switch window pieces 4.

[0089] Furthermore, the transfer and pushing mechanism 15 also includes a driven linear slide 25, and the material trough plate 18 is fixedly installed on the linear slide 25. The material trough plate 18 slides linearly with the linear slide 25 so that the six through slots 19 are aligned and positioned with the vibration transmission track 24 or the six material distribution slots 23 of the equidistant differential mechanism 16.

[0090] Furthermore, the vibration transmission track 24 includes a double track 26, which improves the efficiency of single transmission of the viewing window 4. In this embodiment, the material trough plate 18 has six through slots 19. The double track 26 can align with two through slots 19 at a time. In a single transfer cycle, the material trough plate 18 only needs to move three times to complete the handover of the six viewing windows 4 with the double track 26. In this design, the linear slide table 25 slides linearly, allowing the six material trough plates 18 to dock with the vibration transmission track 24 and also to align and position with the six material troughs 23 of the equidistant differential mechanism 16. The material trough plate 18 acts like an airport shuttle bus, completing the batch transfer of the viewing windows 4 under the drive of the linear slide table 25. This structure not only enables rapid handover of the smaller viewing windows 4 but also effectively improves the compactness of the structure.

[0091] In this embodiment, the equidistant differential mechanism 16 further includes a sliding guide frame 27 and a differential assembly 28. The material distribution plates 22 are slidably connected to the sliding guide frame 27, and each material distribution plate 22 has a fixed terminal 29 and a sliding terminal 30 at its lower end. The differential assembly 28 includes six independent differential segments 31, each with a fixed connection end 32 and a sliding limiting groove 33. Adjacent material distribution plates 22 are connected through a differential segment 31, wherein the fixed terminal 29 is slidably connected to the sliding limiting groove 33 of the differential segment 31, and the fixed terminal 29 is fixedly connected to the fixed connection end 32 of the differential segment 31. In this design, the six differential segments 31 constituting the differential assembly 28 have identical structures, and the six material distribution plates 22 cooperate with the differential assembly 28, easily achieving the merging and equidistant separation of the six material distribution plates 22.

[0092] Please see Figure 11Furthermore, a first linear drive assembly 34 is installed on the sliding guide frame 27. The first linear drive assembly 34 is connected to the innermost material distribution plate 22 on the sliding guide frame 27 via an L-shaped bend 39. The first linear drive assembly 34 cooperates with the differential assembly 28 to separate the six material distribution plates 22 at equal intervals on the sliding guide frame 27. In this design, the first linear drive assembly 34 drives the innermost material distribution plate 22 to move, and the innermost material distribution plate 22 pulls the adjacent material distribution plate 22 to move, and so on, so that the material distribution plates 22 separate at equal intervals in sequence, which facilitates the material handling mechanism 40 to pick up materials.

[0093] In this embodiment, the pusher assembly 17 is disposed on one side of the linear slide 25, located behind the material distribution plate assembly 21. The pusher assembly 17 includes a second linear drive assembly 35 for driving the six inserts A20 to move back and forth.

[0094] In this embodiment, a stroke sensor A36 for auxiliary positioning is fixedly installed on the linear slide 25. The stroke sensor A36 enables the linear slide 25 to move and position.

[0095] II. Transfer Mechanism (Please refer to...) Figure 13-17 )

[0096] Please see Figure 13 , Figure 16 , Figure 17 In this embodiment, the transfer mechanism 40 includes a frame 41, a vertical transfer plate 42, and a horizontal transfer plate 43. The vertical transfer plate 42 is slidably connected to the frame 41 via a Y-axis drive mechanism 44, and the horizontal transfer plate 43 is slidably connected to the vertical transfer plate 42 via an X-axis drive mechanism 45. A first mounting plate 46 is fixedly connected to the horizontal transfer plate 43, and six negative pressure suction heads 47 are rotatably mounted on the first mounting plate 46. The negative pressure suction heads 47 adsorb the viewing window 4 in the dispensing trough 23. The first mounting plate 46 is provided with a posture adjustment assembly 49, which is used to drive the negative pressure suction heads 47 to rotate so as to adjust the posture of the viewing window 4.

[0097] In this design, the vertical transfer plate 42 moves up and down relative to the frame 41 under the drive of the Y-axis drive mechanism 44, aligning the six negative pressure suction heads 47 with the six viewing windows 4 on the material distribution plate group 21. After the negative pressure suction heads 47 adsorb the viewing windows 4, they rotate axially under the action of the negative pressure suction head 47 attitude adjustment component 49, so that the orientation of the viewing windows 4 adapts to the installation requirements of the next station (viewing window 4 installation station). After the attitude adjustment is completed, the horizontal transfer plate 43 moves horizontally under the drive of the X-axis drive mechanism 45, synchronously transporting the six viewing windows 4 to the viewing window 4 installation station for the next installation process. Through the cooperation of the vertical transfer plate 42, the horizontal transfer plate 43, the X-axis drive mechanism 45, the Y-axis drive mechanism 44, the negative pressure suction heads 47, and the attitude adjustment component 49, the batch automatic transfer and attitude adjustment of the viewing windows 4 between different stations are realized, which greatly improves the automation level of the automatic assembly equipment for air switch viewing windows 4.

[0098] Please see Figure 13 , Figure 14 In this embodiment, the attitude adjustment assembly 49 includes a linear drive assembly 50 and a drive rod 51. Driven by the linear drive assembly 50, the drive rod 51 moves horizontally along the length of the first mounting plate 46. The drive rod 51 drives the negative pressure suction head 47 to rotate axially via a six-gear rack assembly to adjust the orientation of the viewing window 4. In this design, the synchronous adjustment of the attitude of the six viewing windows 4 is achieved through the cooperation of the linear drive assembly 50, the drive rod 51, and the gear rack assembly. Furthermore, the gear rack assembly includes a rack 52 fixedly mounted on one side of the drive rod 51 and a gear 53 fixedly sleeved with the negative pressure suction head 47.

[0099] Please see Figure 13 In this embodiment, a stroke sensor B54 is fixedly mounted on the first mounting plate 46. The stroke sensor B54 cooperates with the baffle 55 of the drive rod 51 for zero-point positioning of the drive rod 51. By setting the stroke sensor B54, the adjustment accuracy of the attitude adjustment assembly 49 is effectively improved.

[0100] For further details, please refer to Figure 14-15 The upper end of the negative pressure suction head 47 is connected to a negative pressure pump (not shown in the attached diagram), and the lower end of the negative pressure suction head 47 is formed with a suction hole 48 that mates with the viewing window 4. Furthermore, the suction hole 48 is a rectangular hole that fits with the viewing window 4 with a clearance.

[0101] Please see Figure 13 In this embodiment, both the X-axis drive mechanism 45 and the Y-axis drive mechanism 44 include a linear drive mechanism and a guide rail. Furthermore, the linear drive mechanism in the X-axis drive mechanism 45 is a drive cylinder, and the linear drive mechanism in the Y-axis drive mechanism 44 uses a synchronous belt drive.

[0102] Please see Figure 4-5In this embodiment, the detection device 13 employs a visual recognition component, which is positioned along the transport path of the viewing window 4. This ensures that the posture of all viewing windows 4 can be detected by the visual recognition component, which then feeds the detection results back to the controller (not shown in the attached diagram). In this design, during the detection process, the visual recognition component feeds back the location number of defective products to the controller. The controller then controls the automatic plastic casing unloading and sorting device 12 to remove the defective products, thus achieving automatic sorting. Furthermore, the visual recognition component identifies two scenarios: the negative pressure suction head 47 not adhering to the viewing window 4 and the viewing window 4 being in an incorrect posture. Both scenarios indicate that the viewing window 4 cannot be correctly installed in subsequent operations, resulting in defective products.

[0103] III. Automatic feeding device for plastic casings (see also) Figure 18-19 )

[0104] Please see Figure 18-19 In this embodiment, the automatic plastic shell feeding device 9 includes a feeding platform 59, six storage mechanisms 60, and a pushing mechanism 61. The six storage mechanisms 60 are linearly arranged and fixedly installed on the feeding platform 59, with six plastic shells 1 vertically stacked in each storage mechanism 60. A carrying platform 8 is located on one side of the discharge port 62 of the storage mechanism 60, and the carrying platform 8 has six mounting positions 63 corresponding one-to-one with the discharge port 62 of the storage mechanism 60. The pushing mechanism 61 is slidably installed on the feeding platform 59, located on the opposite side of the discharge port 62 of the storage mechanism 60. The pushing mechanism 61 includes six push plates A64, which are respectively arranged corresponding to the six storage mechanisms 60. Driven by the driving device 65, the pushing mechanism 61 uses the six push plates A64 to simultaneously push the plastic shells 1 at the bottom of the six storage mechanisms 60 to the six mounting positions 63 on the carrying platform 8, completing the batch feeding operation of the plastic shells 1.

[0105] In this design, the operator pre-places a batch of plastic shells 1 into six storage mechanisms 60. When the automatic plastic shell feeding device 9 is working, the pushing mechanism 61 operates periodically under the drive of the drive device 65. Using six push plates A64, the plastic shells 1 located at the bottom of the six storage mechanisms 60 are simultaneously pushed to the six mounting positions 63 of the platform 8. The pushing mechanism 61 completes the feeding operation of the plastic shells 1 before each working cycle of the automatic assembly device of the viewing window 4, thus realizing the automation of batch feeding of plastic shells 1.

[0106] Please see Figure 18-19In this embodiment, the discharge port 62 of the storage mechanism 60 is located at the bottom of the storage mechanism 60, near the platform 8. The pusher plate A64 of the pushing mechanism 61 is inserted from the opposite side of the discharge port 62 to push the plastic shell 1 out of the discharge port 62. In this design, by setting the discharge port 62 at the bottom of the storage mechanism 60, gravity can be used to automatically fill in the lower plastic shell 1, thereby achieving automatic continuous feeding.

[0107] Please see Figure 18-19 In this embodiment, the storage mechanism 60 includes four limiting columns, which are fixedly installed on the upper surface of the feeding platform 59 and cooperate to form a space for stacking the plastic shell 1. Each of the four limiting columns is formed with a right-angle limiting groove 66 that respectively mates with the four side edges of the plastic shell 1. The space for stacking the plastic shell 1 is formed by the four limiting columns, which simplifies the structure of the storage mechanism 60.

[0108] Furthermore, the four limiting columns that make up the material storage mechanism 60 include two front limiting columns 67 and two rear limiting columns 68. The bottom of the right-angle limiting groove 66 of the front limiting column 67 is provided with a discharge notch 69, and the two opposite discharge notches 69 cooperate to form a discharge port 62.

[0109] Please see Figure 18-19 In this embodiment, the pushing mechanism 61 includes a horizontal plate 70 and six push plates A64, which are fixedly connected to the horizontal plate 70. The horizontal plate 70 is slidably connected to the feeding table 59, and under the action of the driving device 65, it drives the six push plates A64 to synchronously push the bottom plastic shell 1 out. Furthermore, the driving device 65 can be a driving cylinder.

[0113] In this design, six plastic shells 1 are sequentially installed on the mounting positions 63 of the stage 8. The gripping component 79 of the opening mechanism 77 separates the upper shell 2 and lower shell 3 of the plastic shell 1, exposing the slot 6. The insertion part 76 is aligned with the slot 6 under the action of the spatial position adjustment component 74, and the viewing window 4 is pushed into the slot 6 with the cooperation of the positioning guide component 75.

The opening mechanism 77 separates the upper housing 2 and the lower housing 3 and raises the upper housing 2 to a position that does not interfere with the installation mechanism 71, preparing for the next step of the installation operation of the installation mechanism 71.

[0116] Please see Figure 25 , Figure 26In this embodiment, the spatial position adjustment component 74 of the mounting mechanism 71 includes an X-axis linear drive component 88, a vertical frame plate 89, and a first Y-axis linear drive component 90. The vertical frame plate 89 is slidably connected to the second bracket 73 via the X-axis linear drive component 88, and the insertion part 76 is slidably connected to the vertical frame plate 89 via the first Y-axis linear drive component 90. In this design, the insertion part 76 moves back and forth along the X-axis under the drive of the X-axis linear drive component 88, and moves up and down along the Y-axis under the drive of the first Y-axis linear drive component 90.

[0117] Please see Figure 25 , Figure 26 In this embodiment, the plug-in portion 76 includes a second mounting plate 91 and six plug-in assemblies 92.

[0120] V. Automatic Plastic Shell Unloading and Sorting Device (Please refer to...) Figure 28-32 )

[0121] Please see Figure 28-32In this embodiment, the automatic plastic shell unloading and sorting device 12 includes: a platform 8, a conveying mechanism, and a sorting mechanism. The platform 8 is mounted on the upper surface of the workbench 7 at both ends via first brackets 102, and the platform 8 is rotatably connected to the first brackets 102 via a rotary drive device 122. Six assembled plastic shells 1 are placed on the platform 8. The conveying mechanism is located below the platform 8 and includes a first conveying groove 104 and a pusher mechanism 105. The sorting mechanism includes a pusher mechanism 106 disposed on the upper surface of the workbench 7 and six rejecting components 107 disposed on the lower surface of the workbench 7, with each of the six rejecting components 107 corresponding one-to-one with the six plastic shells 1. Driven by the rotary drive device 122, the platform 8 flips to the side closer to the first transfer groove 104, and the six plastic shells 1 are introduced into the first transfer groove 104. The six plastic shells 1 are pushed towards the sorting mechanism by the push rod mechanism 105. The rejecting component 107 rejects the defective products according to the feedback from the detection device 13 and introduces them into the defective product recycling box 101.

[0122] In this design, the platform 8, driven by the rotary drive device 122, flips towards the side closest to the first transfer groove 104, guiding six plastic shells 1 into the first transfer groove 104. The six plastic shells 1 then move towards the sorting mechanism under the pusher mechanism 105, and, with the help of six rejection components 107, guide the plastic shells 1 with missing viewing windows 4 into the defective product recycling bin 101 below the workbench 7. Through the cooperation of the platform 8, the transfer mechanism, and the sorting mechanism, batch unloading and sorting of the plastic shells 1 are achieved, greatly improving the automation and efficiency of unloading.

[0123] Please see Figure 31 In this embodiment, the first transmission groove 104 is fixedly mounted on the workbench 7, including two parallel guide plates 108, with six plastic shells 1 arranged sequentially between the two guide plates 108. A push rod mechanism 105 is mounted on the bottom surface of the workbench 7, including a push rod 109 and a synchronous pulley assembly 110 that drives the push rod 109 to move linearly. A guide groove 111 for the push rod 109 to move is provided on the workbench 7. In this design, the push rod 109 reciprocates intermittently under the drive of the synchronous pulley assembly 110. Specifically, within one pushing cycle, the push rod 109 moves from the starting end 123 to the ending end 124 of the guide groove 111, while a row of plastic shells 1 is pushed to the sorting mechanism. Then, before the next pushing cycle, the push rod 109 returns to the starting end 123 of the guide groove 111, preparing for the next pushing.

[0124] In this embodiment, an auxiliary unloading mechanism 112 is provided on one side of the first transmission channel 104. The auxiliary unloading mechanism 112 includes a fourth bracket 113, a baffle 114, and a first linear drive device 115 for driving the baffle 114 closer to or away from the platform 8.

[0125] In this embodiment, the rejection assembly 107 includes a support block 116 for supporting the plastic shell 1 and a third linear drive device 117 for driving the support block 116 to extend and retract. The third linear drive device 117 is electrically connected to the controller. A rectangular trough 118 is provided on the workbench 7. The support block 116 extends and retracts in the rectangular trough 118 along the width direction of the rectangular trough 118. The defective product recycling box 101 is located directly below the rectangular trough 118. In this design, after receiving feedback from the detection device 13, the controller controls the corresponding rejection assembly to act, causing the corresponding plastic shell 1 to leak out of the rectangular trough 118 and fall into the defective product recycling box 101 below, while good products remain on the workbench 7. Through the cooperation of the detection device 13, the controller, and the six rejection assemblies 107, the effect of automatically rejecting defective products (plastic shells 1 that do not have the viewing window 4 correctly installed) is achieved.

[0126] In this embodiment, the pushing mechanism 106 includes a push plate C119 and a second linear drive device 120. The sorting area on the workbench 7 is provided with a good product storage area 121. Under the drive of the second linear drive device 120, the push plate pushes the assembled plastic shell 1 to the good product storage area 121 for temporary storage.

[0127] The good product storage area is fixedly equipped with a first slide plate 125 and a second slide plate 126. Clamping plates 127 are slidably mounted on the first slide plate 125 and the second slide plate 126, with both ends of the clamping plates 127 slidably connected to slide grooves 128 on the first slide plate 125 and the second slide plate 126. The push plate C119 and the clamping plates 127 cooperate to form a second transmission groove that guides the movement of the plastic casing.

[0128] During operation, the automatic plastic casing feeding device 9 and the automatic window sheet feeding and transfer device 10 are responsible for the automatic batch feeding of plastic casings 1 and window sheets 4, respectively. The transfer mechanism 40 transfers the window sheets in batches to the top of the loading platform (see reference). Figure 12 The viewing window is placed into the positioning guide assembly 75 and the rectangular through hole 98. Then, the six viewing windows 4 are simultaneously inserted into the slots 6 at the viewing holes 5 of the lower housing 3 by the automatic viewing window installation device 11. The automatic plastic shell unloading and sorting device 12, the detection device 13 and the controller work together to remove defective products and collect good products.

[0129] In summary, this invention achieves automatic batch feeding of the plastic casing and the window piece through the automatic feeding and transfer device for the plastic casing and the automatic feeding and transfer device for the window piece, respectively; the automatic window piece installation device synchronously inserts six window pieces into the slots at the viewing holes of the lower casing; and the automatic unloading and sorting device for the plastic casing, along with the detection device and controller, enables the rejection of defective products and the collection of good products. This invention fully realizes the automatic assembly of the air switch window piece, greatly improving the assembly efficiency of the window piece and adapting to large-scale production. Simultaneously, the real-time monitoring of the assembly operation through a visual recognition component significantly improves the yield rate. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.
