Description

Technical Field

[0001] This application relates to the technical field of timer assembly, and in particular to a timer screw assembly method and assembly equipment. Background Technology

[0002] A timer is a mechanical or electronic device used for timing and counting. Currently, most timers on the market have a square cover with a storage slot on the back for holding various electrical components of the timer. A post is fixed at the corner of the front of the timer, and the center of the post is hollow. Screws are installed inside the post to facilitate the subsequent production and processing of the timer.

[0003] In the production process of timers in the existing technology, the operator usually places the outer shell on the clamping device and then manually aligns and inserts the screw into the insert; or, the operator places several outer shells on the vibrating screen, and the vibrating screen feeds the outer shells to be separated into the worktable of the circular rotating disc through the hopper, and then the robot inserts the screw into the corresponding insert.

[0004] However, whether screws are installed manually or automatically, the assembled casing needs to be stored and then transferred to another machine for the processing of electrical components. The casing is then turned upside down, and the various electrical components are placed into the storage slot. This repeated handling of the casing makes it easy for the screws to come out of the casing, and also causes problems such as poor production continuity and low production efficiency of timers. Summary of the Invention

[0005] To further improve the continuity of timer production, this application provides a timer screw assembly method and assembly equipment, which can reduce the number of times the housing is transferred, reduce the phenomenon of screws coming out of the housing, improve production efficiency, and reduce labor intensity.

[0006] Firstly, this application provides a timer screw assembly method, which adopts the following technical solution:

[0007] A method for assembling a timer screw includes the following processing steps:

[0008] Shell loading: The shell is placed from the top of the loading channel and slides onto the top surface of the first support.

[0009] Screw feeding: Place several screws in the vibrating screen, start the vibrating screen, and the screws will be neatly arranged side by side in the feeding guide rail, continuously supplying screws to the clamping seat.

[0010] Shell feeding: The output end of the automatic feeding mechanism is assembled with the support plate. The first support is fixed at one end of the support plate near the feeding channel, and the second support is fixed at the other end of the support plate. The support plate is driven to move forward by the automatic feeding mechanism. The screw feeding robot is aligned with the top surface of the first support and the second support is aligned with the output port of the flipping mechanism.

[0011] Adding screws to the outer casing: The screw feeding robot picks up the screws from the clamping base and inserts them into the inserts of the outer casing to obtain the initial finished outer casing.

[0012] Automatic flipping of the initial shell product: After the automatic feeding mechanism drives the second support to align with the output port of the flipping mechanism, the automatic feeding mechanism first moves downward and then returns to the initial position, and the flipping mechanism drives the initial shell product to flip 180°.

[0013] Initial shell product pushing: The pushing mechanism pushes the initial shell product to the top surface of the transmission mechanism.

[0014] Shell transfer: The transfer mechanism transfers the pre-finished shell to the mounting mechanism, which then installs the electrical components into the storage slot of the pre-finished shell to obtain the finished shell.

[0015] By adopting the above technical solution, after the processing steps of shell feeding, screw feeding, shell feeding, shell screw installation, automatic flipping of the initial shell product, shell pushing, and shell transfer, the two purposes of installing screws on the shell and flipping the initial shell product can be achieved on one machine. Compared with the existing technology, it effectively reduces the number of shell transfers, reduces the phenomenon of screws coming out of the shell, improves production efficiency, and further improves the continuity of timer production, meeting production needs.

[0016] Preferably, the outer casing loading process also includes the following processing steps:

[0017] Shell positioning and feeding: The opposite side walls of the shell are pressed against the two elastic guide plates of the feeding channel. After the external force applied to the shell is released, the shell falls freely and passes through the inlet formed between the two elastic guide plates. The shell slides and connects with the inner side wall of the feeding channel. The shell lands on the top surface of the first support. At the same time, the positioning post set on the top surface of the first support is inserted into the positioning hole of the shell.

[0018] By adopting the above technical solution, the operator presses the opposite side walls of the outer shell against the two elastic guide plates of the feeding channel. After releasing the external force applied to the outer shell, the outer shell falls freely on the top surface of the first support, completing the feeding of the outer shell. The setting of the elastic guide plates can play a restraining role in preventing and correcting erroneous behavior, so that the operator can complete the feeding action of the outer shell without spending attention or experience. This reduces the risk of equipment or personal injury caused by operator error in feeding, helps to improve the safety of operators and improve production continuity.

[0019] Preferably, the machining step of adding screws to the outer casing also includes the following machining processes:

[0020] Shell clamping: The screw feeding robot inserts the screw into the insertion post, and at the same time, the clamping mechanism clamps the shell to the top surface of the first support.

[0021] By adopting the above technical solution, the clamping mechanism clamps the outer shell, which helps to improve the stability of the outer shell placed on the top surface of the first support, allowing the screw feeding robot to easily insert the screw into the insertion post.

[0022] Preferably, the automatic flipping process of the initial shell product further includes the following processing steps:

[0023] Automatic feeding mechanism stroke adjustment: The first support is equipped with an identification sensor. When the automatic feeding mechanism is in the initial position, the identification sensor is aligned with the shell placed in the feeding channel. The shell is placed on the first support. The automatic feeding mechanism is started. The shell pre-finished product placed on the top surface of the second support is transferred to the input end of the flipping mechanism. The reverse transfer distance of the automatic feeding mechanism is consistent with the forward transfer distance. The automatic feeding mechanism repeats the movement steps.

[0024] The initial shell product is flipped and limited: The flipping mechanism includes a limiting mechanism and a flipping drive assembly. The output end of the flipping drive assembly is assembled with the limiting mechanism. The limiting mechanism includes an input limiting seat and an output limiting seat with the same shape and structure. The input limiting seat is located at one end near the feeding channel. The automatic feeding mechanism drives the second support seat to move to the middle of the input limiting seat. The initial shell product transitions from the second support seat to the top surface of the input limiting seat. When the flipping drive assembly drives the limiting mechanism to flip 180°, the input limiting seat and the output limiting seat alternate.

[0025] By adopting the above technical solution, in the process of flipping and limiting the initial shell product, it is ensured that the initial shell product is not easily detached from the flipping mechanism when it is flipped 180°, which helps to improve the connection stability between the initial shell product and the flipping mechanism. In the process of adjusting the stroke of the automatic feeding mechanism, the reverse transfer distance of the automatic feeding mechanism is consistent with the forward transfer distance. The automatic feeding mechanism repeats the movement steps, which can repeatedly realize the two functions of adding screws to the shell and flipping the initial shell product, thereby improving the continuity of timer production and improving production efficiency.

[0026] Preferably, the outer casing loading process also includes the following processing steps:

[0027] Timed feeding of outer shells: Several outer shells are neatly stacked in the feeding channel. At the same time, the timed cylinder is activated. The output end of the timed cylinder is pressed against the clamping head. The clamping head presses against the outer wall of the outer shell located at the bottom of the feeding channel. The side of the outer shell away from the clamping head presses against the inner wall of the feeding channel.

[0028] By adopting the above technical solution, the timing cylinder drives the clamping head to press against the outer wall of the housing. At the same time, the side of the housing away from the clamping head presses against the inner wall of the feeding channel. This can control the feeding speed of the housing to adapt to the timing of screw installation on the housing and automatic flipping of the initial finished product of the housing. This helps to reduce material blockage and ensure the continuity of timer production.

[0029] Preferably, the shell pushing process further includes the following processing steps:

[0030] Parallel feeding of the initial shell product: After the flipping drive assembly drives the limiting mechanism to flip 180°, the feeding mechanism is started. The feeding mechanism pushes the flipped initial shell product parallel from the top surface of the second support to the top surface of the transmission mechanism, and then returns to the initial position to repeat the feeding process.

[0031] By adopting the above technical solution, the pre-finished shell that has been flipped can be quickly pushed to the top surface of the conveying mechanism under the action of the pushing mechanism, so as to make way for the next pre-finished shell, which helps to improve production continuity, reduce material blockage, and improve production efficiency.

[0032] Secondly, this application provides a timer screw assembly device that uses an assembly method to install screws onto a timer, employing the following technical solution:

[0033] A timer screw assembly device, comprising:

[0034] Base;

[0035] The feeding channel is fixed to the top surface of the input end of the machine base. A hollow groove is opened through the middle of the feeding channel, and several shells are neatly stacked inside the feeding channel.

[0036] An automatic feeding mechanism is located at the bottom of the machine base;

[0037] A support plate is mounted on the output end of the automatic feeding mechanism. A first support seat is provided at one end of the support plate near the feeding channel, and a second support seat is provided at the other end.

[0038] The vibrating screen plate is fixed to the top surface of the machine base, and several screws are placed inside the vibrating screen plate.

[0039] The feeding guide rail is located at the output end of the vibrating screen plate;

[0040] The screw feeding robot is installed on the machine base near the output end of the feeding guide rail.

[0041] A flipping mechanism is located on the top surface of the output end of the machine base;

[0042] The material pushing mechanism is located in the middle of the flipping mechanism and is used to unload the initial finished shell.

[0043] The transmission mechanism is installed on the top surface of the machine base, near the pusher mechanism and away from the feed channel.

[0044] By adopting the above technical solution, the shell is placed into the feeding channel, ensuring that the feeding position of each shell is the same, that is, that each timer falls on the first support, improving the positional accuracy of shell feeding. At the same time, the screw feeding robot picks up the screws and installs screws on the shells placed on the second support. Under the action of the automatic feeding mechanism, the shells placed on the first support can be quickly transferred to the bottom of the screw feeding robot and the shells placed on the second support can be transferred to the flipping mechanism. The screw feeding robot repeats the screw installation action, and the flipping mechanism flips the shells 180°. Then, with the cooperation of the pushing mechanism and the conveying mechanism, the shells can be unloaded. Compared with the prior art, this application makes the shell screw installation process more continuous by rationally arranging the spatial positions of each mechanism. Moreover, it has a high degree of mechanization, requires less operator intervention, helps to reduce labor intensity and save production costs.

[0045] Preferably, the conveying mechanism includes a conveyor belt mounted on the machine base, and the flipping mechanism includes an output limiting seat located at one end of the machine base near the feeding channel. The height of the output limiting seat from the working ground is greater than the height of the conveyor belt from the working ground. The pushing mechanism transfers the pre-finished outer shell on the output limiting seat to the top surface of the conveyor belt.

[0046] By adopting the above technical solution, the height of the output limiting seat from the working ground is greater than the height of the conveyor belt from the working ground, so that there is a drop between the output limiting seat and the conveyor belt, allowing the initial finished product of the outer shell to easily transition to the top surface of the conveyor belt, which helps to improve the unloading efficiency.

[0047] Preferably, the feeding channel includes two elastic guide plates, which are symmetrically arranged along the center line of the feeding channel. The elastic guide plates are fixed to the side wall of the feeding channel and are inclined downward from the top wall of the feeding channel towards the center. A buffer spring is connected between the elastic guide plate and the side wall of the feeding channel.

[0048] By adopting the above technical solution, the elastic guide plate and the buffer spring work together to make the elastic guide plate have good elasticity. When the operator places the shell at the entrance of the feeding channel, the elastic guide plate can provide guidance for the shell, so that the shell can slide into the feeding channel better, thereby realizing the feeding of the shell.

[0049] Preferably, the automatic feeding mechanism includes a vertical drive component, a slide block, a slide rail, and a horizontal drive assembly. The slide rail is installed at the bottom of the machine base, and the length direction of the slide rail is consistent with the transmission direction of the housing. The slide block is slidably connected to the slide rail. The output end of the horizontal drive assembly is assembled with the slide block. The horizontal drive assembly is used to drive the slide block to move along the slide rail. The vertical drive component is installed on the top surface of the slide block, and the output end of the vertical drive component is assembled with the bottom surface of the support plate.

[0050] By adopting the above technical solution, under the drive of the horizontal drive component, the slide can easily reciprocate along the slide rail, thereby enabling the support plate to repeatedly transport the outer shell and the initial outer shell product. Furthermore, under the drive of the vertical drive component, the support plate can move vertically, ensuring that the support plate does not interfere with the flipping mechanism during the return stroke, thus improving the smoothness of the outer shell and the initial outer shell product transported by the support plate.

[0051] In summary, this application includes at least one of the following beneficial technical effects:

[0052] 1. After the processing steps of shell feeding, screw feeding, shell feeding, shell screw installation, shell initial finished product automatic flipping, shell initial finished product pushing, and shell transfer, the two purposes of installing screws on the shell and flipping the shell initial finished product can be achieved on one machine. Compared with the existing technology, it effectively reduces the number of shell transfers, reduces the phenomenon of screws coming out of the shell, improves production efficiency, and further improves the continuity of timer production, meeting production needs.

[0053] 2. The flexible guide plate can play a restraining role in preventing and correcting erroneous behavior, allowing operators to complete the loading action of the shell without having to pay attention or have experience. This reduces the risk of equipment or personal injury caused by operator error loading, helps to improve the safety of operators and improve production continuity.

[0054] 3. The timing cylinder drives the clamping head to press against the outer wall of the housing, while the side of the housing away from the clamping head presses against the inner wall of the feeding channel. This can control the feeding speed of the housing to adapt to the timing of screw installation on the housing and automatic flipping of the initial finished product, which helps to reduce material blockage.

[0061] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0062] In a first aspect, embodiments of this application disclose a method for assembling timer screws.

[0063] Reference Figure 1 and Figure 2 A method for assembling a timer screw includes the following processing steps:

[0064] Shell loading: Shell 2 is placed from the top of the loading channel 4 and slides onto the top surface of the first support.

[0065] Shell positioning and feeding: The operator holds the shell 2 with the front of each shell 2 facing up. The operator's thumb supports the back of the shell 2 and the four fingers hold the front of the shell 2. When the shell 2 is placed parallel to the top of the feeding channel 4, the operator's thumb is distributed on the relief opening 43 of the feeding channel 4, so that the opposite side walls of the shell 2 are pressed against the two elastic guide plates 41 of the feeding channel 4. After releasing the external force applied to the shell 2, the shell 2 falls freely and passes through the inlet formed between the two elastic guide plates 41. The shell 2 slides and connects with the inner side wall of the feeding channel 4. The shell 2 lands on the top surface of the first support. At the same time, the positioning post 753 set on the top surface of the first support is inserted into the positioning hole of the shell 2.

[0066] Timed feeding of outer shells: Several outer shells 2 are neatly stacked in the feeding channel 4 according to the above steps. At the same time, the timed cylinder 91 is activated. The output end of the timed cylinder 91 is pressed against the clamping head 92. The clamping head 92 presses against the outer wall of the outer shell 2 located at the bottom of the feeding channel 4. The side of the outer shell 2 away from the clamping head 92 presses against the inner wall of the feeding channel 4. This ensures that the movement speed of the clamping head 92 driven by the timed cylinder 91 is consistent with the speed at which the outer shell 2 falls from the bottom of the feeding channel 4 to the top surface of the first support, thereby ensuring the smooth feeding of the outer shell 2 and reducing the occurrence of material blockage.

[0067] Screw feeding: Place several screws in the vibrating screen plate 5, start the vibrating screen plate 5, the vibrating screen plate 5 acts as a power source to shake the screws apart, so that the screws are neatly arranged side by side in the feeding guide rail, and continuously supply screws to the clamping seat.

[0068] Shell feeding: The output end of the automatic feeding mechanism 7 is assembled with the support plate 75. The length of the support plate 75 is the distance between the bottom of the feeding channel 4 and the bottom of the screw feeding robot 6. The first support is fixed at one end of the support plate 75 near the feeding channel 4, and the second support is fixed at the other end of the support plate 75. The direction of movement from the feeding channel 4 to the screw feeding robot 6 is set as forward transfer, and the opposite is reverse transfer.

[0069] Under the action of the automatic feeding mechanism 7, the support plate 75 is driven to move forward, so that the screw feeding robot 6 is aligned with the top surface of the first support and the second support is aligned with the output port of the flipping mechanism 8.

[0070] Adding screws to the outer shell: The screw feeding robot 6 picks up the screws from the clamping seat and inserts them into the insert 21 placed in the outer shell 2, thus obtaining the initial finished outer shell 3.

[0071] Shell clamping: The screw feeding robot 6 inserts the screw into the insertion post 21. At the same time, the clamping mechanism clamps the shell onto the top surface of the first support, which helps to improve the stability of the shell 2 placed on the top surface of the first support, allowing the screw feeding robot 6 to easily insert the screw into the insertion post 21.

[0072] Automatic flipping of the initial shell product: After the automatic feeding mechanism 7 drives the second support to align with the output port of the flipping mechanism 8, the automatic feeding mechanism 7 first moves downward and then returns to the initial position. The flipping mechanism 8 drives the initial shell product 3 to flip 180°.

[0073] Specifically, the stroke adjustment of the automatic feeding mechanism: an identification sensor is provided on the first support. When the automatic feeding mechanism 7 is in the initial position, the identification sensor is aligned with the outer shell 2 placed in the feeding channel 4, and the outer shell 2 is placed on the first support.

[0074] The automatic feeding mechanism 7 is started in the forward direction, so that the outer shell 2 placed on the top surface of the first support is transferred to the bottom of the screw feeding robot 6, and the initial finished outer shell 3 placed on the top surface of the second support is transferred to the input end of the flipping mechanism 8. After the forward feeding is completed, the automatic feeding mechanism 7 is started in the reverse direction to ensure that the distance of the reverse transfer of the automatic feeding mechanism 7 is consistent with the distance of the forward transfer. The automatic feeding mechanism 7 repeats the movement steps to achieve the effect of repeated feeding.

[0075] The initial shell product is flipped and limited: The flipping mechanism 8 includes a limiting mechanism 81 and a flipping drive assembly 82. The output end of the flipping drive assembly 82 is assembled with the limiting mechanism 81. The limiting mechanism 81 includes an input limiting seat 811 and an output limiting seat 812 with the same shape and structure. The input limiting seat 811 is located at one end near the feeding channel 4. The automatic feeding mechanism 7 drives the second support seat to move to the middle of the input limiting seat 811. The automatic feeding mechanism 7 first moves downward, causing the positioning pin 753 to disengage from the positioning hole. The initial shell product 3 thus transitions from the second support seat to the top surface of the input limiting seat 811, and then moves in the opposite direction to return to the initial position. When the flipping drive assembly 82 drives the limiting mechanism 81 to flip 180°, the input limiting seat 811 and the output limiting seat 812 alternately change, so that the reverse side of the initial shell product 3 placed on the top surface of the output limiting seat 812 faces upward.

[0076] Initial shell product pusher: The pusher mechanism pushes the initial shell product 3 to the top surface of the transmission mechanism.

[0077] Parallel feeding of the initial shell product: After the flipping drive assembly 82 drives the limiting mechanism 81 to flip 180°, the feeding mechanism is started. The feeding mechanism pushes the flipped initial shell product 3 parallel from the top surface of the second support to the top surface of the transmission mechanism, and then moves in the opposite direction and returns to the initial position. The feeding is repeated to ensure the continuity of unloading.

[0078] In this application, the two purposes of adding screws to the outer casing and flipping the initial finished outer casing 3 are achieved on one machine, which effectively reduces the number of times the outer casing 2 is transferred, reduces the phenomenon of screws coming out of the outer casing 2, improves production efficiency, and further improves the continuity of timer production, thus meeting production requirements.

[0079] Secondly, embodiments of this application disclose a timer screw assembly device, which uses an assembly method to install screws onto a timer.

[0080] Reference Figure 1 and Figure 2 A timer screw assembly device includes a base 1 and a feeding channel 4. In this embodiment, the feeding channel 4 is a square feeding channel 4, which is vertically fixed to the top surface of the input end of the base 1. A hollow groove is opened through the middle of the feeding channel 4. The inner four walls of the feeding channel 4 are all smoothly arranged. Several shells 2 are neatly stacked in the feeding channel 4 to reduce the frictional resistance between the outer wall of the shell 2 and the inner wall of the feeding channel 4, thereby reducing the occurrence of material blockage of the shells 2 in the feeding channel 4.

[0081] The feeding channel 4 includes two elastic guide plates 41. The elastic guide plates 41 are made of rubber, which gives them good elasticity and can protect the outer shell 2 when it is unloaded. The two elastic guide plates 41 are symmetrically arranged along the center line of the feeding channel 4. The elastic guide plates 41 are fixed to the short side wall of the feeding channel 4. The elastic guide plates 41 are inclined downward from the top wall of the feeding channel 4 towards the center. A buffer spring 42 is connected between the elastic guide plate 41 and the side wall of the feeding channel 4. When the operator places the outer shell 2 at the entrance of the feeding channel 4, the elastic guide plate 41 can provide guidance for the outer shell 2, so that the outer shell 2 can slide into the feeding channel 4 better, thereby realizing the loading of the outer shell 2. In addition, in order to further improve the convenience of the operator to put the outer shell 2 in, a clearance opening 43 is provided on the long side of the top of the feeding channel 4.

[0082] Reference Figure 2 and Figure 3 The assembly equipment includes an automatic feeding mechanism 7 and a vibrating screen plate 5. The automatic feeding mechanism 7 is located at the bottom of the base 1. A support plate 75 is installed at the output end of the automatic feeding mechanism 7. A first support seat is provided at one end of the support plate 75 near the feeding channel 4, and a second support seat is provided at the other end. The structure of the first support seat and the second support seat is consistent. Positioning pins 753 are fixed on the top surface of both the first support seat and the second support seat, so that the feeding channel 4 is distributed above the support plate 75, and the outer shell 2 rests on the top surface of the first support seat. At the same time, the positioning pins 753 are inserted into the positioning holes of the outer shell 2.

[0083] The two long side walls of the support plate 75 are respectively fixed with baffle plates 76. The extension direction of the baffle plates 76 is consistent with the transmission direction of the outer shell 2. The cross section of the baffle plates 76 is "U" shaped, so that the openings of the two baffle plates 76 are directly opposite each other. After the outer shell 2 falls from the feed channel 4 to the top surface of the first support, it is slidably connected to the middle of the baffle plates 76 under the drive of the automatic feeding mechanism 7, so as to reduce the situation where the outer shell 2 is thrown out of the baffle plates 76 during the movement process.

[0084] The assembly equipment includes a vibrating screen plate 5 and a screw feeding robot 6. The vibrating screen plate 5 is fixed on the top surface of the base 1. Several screws are placed inside the vibrating screen plate 5. A feeding guide rail is provided at the output end of the vibrating screen plate 5. The input end of the feeding guide rail is connected to the output end of the vibrating screen plate 5. The vibrating screen plate 5 acts as a power source to shake the screws apart and allow them to exit one by one from the output end of the feeding guide rail. The screw feeding robot 6 is located on the base 1 near the output end of the feeding guide rail. A mounting frame is fixed on the top of the base 1 near the screw feeding robot 6. The screw feeding robot 6 is slidably connected to the bottom surface of the mounting frame. At the same time, a clamping mechanism is provided on the bottom surface of the mounting frame. During the process of the screw feeding robot 6 picking up the screws in the feeding guide rail and installing screws on the outer shell 2, the clamping mechanism simultaneously clamps the outer shell 2 placed on the top surface of the first support, which can improve the positioning accuracy of the screw feeding robot 6 inserting the screws into the insertion post 21.

[0085] Furthermore, the assembly equipment also includes a flipping mechanism 8, a pushing mechanism, and a conveying mechanism. The flipping mechanism 8 is located on the top surface of the output end of the machine base 1, and the pushing mechanism is located in the middle of the flipping mechanism 8. The pushing mechanism is used to unload the initial finished product 3 of the outer shell. The conveying mechanism is installed on the top surface of the machine base 1, near the pushing mechanism and away from the feeding channel 4. Under the action of the flipping mechanism 8, the initial finished product 3 of the outer shell can be flipped 180°. With the cooperation of the pushing mechanism and the conveying mechanism, the initial finished product 3 of the outer shell can be unloaded. This application achieves two purposes by adding screws to the outer shell and flipping the initial finished product 3 of the outer shell through the assembly equipment, thereby improving production efficiency and further improving the continuity of timer production.

[0086] Reference Figure 2 The automatic feeding mechanism 7 includes a vertical drive component, a slide block 72, a slide rail 73, and a horizontal drive component. The slide rail 73 is installed at the bottom of the base 1, and the length direction of the slide rail 73 is consistent with the transmission direction of the housing 2. The slide block 72 is slidably connected to the slide rail 73. The output end of the horizontal drive component is assembled with the slide block 72. The horizontal drive component is used to drive the slide block 72 to move along the slide rail 73. The vertical drive component is installed on the top surface of the slide block 72, and the output end of the vertical drive component is assembled with the bottom surface of the support plate 75.

[0087] Specifically, the lateral drive assembly includes a drive motor 741 and a connecting screw 742. The connecting screw 742 is rotatably connected to the bottom of the base 1, so that the connecting screw 742 is parallel to the slide rail 73. The bottom of the slide 72 is threadedly connected to the connecting screw 742. The drive motor 741 is fixed to one end of the base 1 near the connecting screw 742. More specifically, the vertical drive component is a drive cylinder 71. The drive cylinder 71 is mounted on the top surface of the slide 72, and the output end of the drive cylinder 71 is assembled with the support plate 75.

[0088] By starting the drive motor 741, the connecting screw 742 rotates, and the slide 72 moves along the length of the connecting screw 742. At the same time, the cooperation between the slide 72 and the slide rail 73 can improve the movement stability of the slide 72, allowing the slide 72 to easily reciprocate along the slide rail 73. This enables the support plate 75 to repeatedly transport the outer shell 2 and the initial outer shell 3. Furthermore, under the drive of the drive cylinder 71, the support plate 75 can move vertically, ensuring that the support plate 75 does not interfere with the flipping mechanism 8 during its return stroke, thus improving the smoothness of the transport of the outer shell 2 and the initial outer shell 3 by the support plate 75.

[0089] In addition, refer to Figure 1 and Figure 2 The mechanical structure and operating principle of the vibrating screen plate 5, the screw feeding robot 6, and the clamping mechanism are all existing technologies and will not be described in detail in the embodiments of this application.

[0090] In order to achieve automatic flipping of the initial shell product 3, refer to Figure 4 and Figure 5 The flipping mechanism 8 includes an input limit seat 811, an output limit seat 812, and a flipping transmission assembly. A connecting rod is fixed between the input limit seat 811 and the output limit seat 812. The input limit seat 811 is located at one end near the feed channel 4, and the output limit seat 812 is located at one end near the transmission mechanism. The output end of the flipping transmission assembly is assembled with the connecting rod. The flipping transmission assembly acts as a power source to drive the input limit seat 811 and the output limit seat 812 to achieve a 180° exchange.

[0091] Specifically, the flipping transmission assembly includes two connecting gears 821, a connecting gear 821 belt, and a flipping starter motor 823. The connecting gears 821 are mounted on the base 1 via shaft connections. The flipping starter motor 823 is connected to the mounting shaft of one of the connecting gears 821. The connecting gear 821 belt meshes with both connecting gears 821 simultaneously. Correspondingly, a sliding groove 824 is provided on the side of the base 1 near the flipping mechanism 8. The extension direction of the sliding groove 824 is consistent with the unloading direction of the initial finished product 3 of the outer shell. A moving block 825 is slidably connected in the sliding groove 824. A fixed shaft is fixed in the middle of the side wall of the moving block 825. A mating gear 822 is rotatably connected to the end of the fixed shaft away from the moving block 825. The mating gear 822 meshes with the outer wall of the connecting gear 821 belt simultaneously. Furthermore, an mounting shaft is fixed on the base 1. A flipping rod 826 is provided between the mounting shaft and the connecting rod, so that one end of the flipping rod 826 is rotatably connected to the mounting shaft and the other end is rotatably connected to the connecting rod.

[0092] When the operator starts the flip start motor 823, the connecting gear 821 can rotate, thereby driving the belt of the connecting gear 821 to rotate, causing the mating gear 822 to move along the length direction of the belt of the connecting gear 821. At the same time, the moving block 825 slides along the sliding groove 824, causing the flip rod 826 to drive the input limit seat 811 and the output limit seat 812 to exchange 180°, thereby causing the shell pre-finished product 3 placed on the top surface of the input limit seat 811 to flip from the front to the back.

[0093] Reference Figure 1 The transmission mechanism includes a transmission belt 11, which is mounted on the base 1. The height of the output limiting seat 812 from the working ground is greater than the height of the transmission belt 11 from the working ground. The pushing mechanism transfers the pre-finished shell 3 on the output limiting seat 812 to the top surface of the transmission belt 11. The pushing mechanism includes an "L"-shaped pushing plate and a pushing cylinder. The pushing cylinder is fixed to the bottom of the base 1. The short side of the pushing plate passes through the middle of the output limiting seat 812. The output end of the pushing cylinder is assembled with the long side of the pushing plate.

[0094] After the initial shell product 3 is flipped, the pusher cylinder is activated, and the pusher plate moves towards one end of the conveyor belt 11, which can transfer the initial shell product 3 placed on the output limit seat 812 to the top surface of the conveyor belt 11. The conveyor belt 11 then transports the initial shell product 3 away, which improves the transfer efficiency of the initial shell product 3.

[0095] The above are all preferred embodiments of this application. These embodiments are merely explanations of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of this application should be covered within the scope of protection of this application.
