Description

Technical Field

[0001] This invention relates to the field of universal joint manufacturing technology, and more specifically, to a method and apparatus for tempering and feeding universal joint bell-shaped covers. Background Technology

[0002] Currently, in the production and processing of universal joint bell covers, heat treatment is a key process to ensure the mechanical properties and reliability of the bell cover. Before the heat treatment process, a specific conveying system is needed to transfer the workpiece to the heat treatment equipment. Existing technologies typically use conveyor belts as the conveying device. Their core function is to receive the universal joint bell cover workpieces to be processed and stably transport them to the carrier belt. The carrier belt then serves as the subsequent transfer carrier, receiving the workpieces from the conveyor belt and further precisely transporting them into the tempering furnace. This provides the necessary pre-transfer guarantee for the standardized heat treatment process of the universal joint bell cover in the tempering furnace.

[0003] However, in the actual operation of the universal joint bell-shaped cover machining involving heat treatment processes, after the workpiece (universal joint bell-shaped cover) arrives, it is pushed to the carrier belt by a telescopic cylinder, and then transported to the heat treatment tempering furnace by the carrier belt. But this can easily lead to excessive accumulation of workpieces on the carrier belt. At the same time, under the pushing force of the telescopic cylinder or the influence of the vibration of the carrier belt, the workpiece may also be pushed over. The accumulated or tilted workpieces will directly collide with the side of the inlet of the tempering furnace. On the one hand, this will hinder the normal operation trajectory of the carrier belt. On the other hand, the resistance generated by the collision will cause the carrier belt to jam. The continued jamming will further lead to the overload damage of the drive source that drives the carrier belt. Summary of the Invention

[0004] To address the problem that universal joint bell covers are prone to jamming during transport, leading to damage to the drive source, this invention provides a method and apparatus for tempering and feeding universal joint bell covers.

[0005] In a first aspect, the present invention provides a method for tempering and feeding a universal joint bell-shaped cover, the method comprising:

[0006] Control the first conveyor belt to transport the workpiece to the preset position;

[0007] Based on the workpiece being located at the preset position, the pushing component is controlled to push the workpiece along the second conveyor belt until the workpiece reaches the third conveyor belt; wherein, there is an angle between the first conveyor belt and the second conveyor belt;

[0008] Based on the workpiece passing through the second conveyor belt, the dwell time of the workpiece in the preset area of ​​the second conveyor belt is obtained;

[0009] Based on the fact that the dwell time is greater than a preset time, the first conveyor belt, the pushing component, and the third conveyor belt are controlled to stop working.

[0010] In some embodiments, the state of the preset position is obtained based on the workpiece being located on the first conveyor belt;

[0011] Based on the fact that the preset position is in an unloaded state, the control is executed to transport the workpiece to the preset position via the first conveyor belt;

[0012] Based on the preset position being in the material receiving state, the first conveyor belt is controlled to remain stationary.

[0013] In some embodiments, the cumulative accumulation number is incremented by 1 based on the fact that the dwell time is less than the preset time.

[0014] Based on the accumulation quantity reaching a preset quantity, the third conveyor belt is controlled to convey a preset distance; wherein, the conveying direction of the third conveyor belt forms an angle with the length direction of the second conveyor belt.

[0015] In some embodiments, the number of stacked items is reduced to zero based on the distance conveyed by the third conveyor belt to the preset distance.

[0016] In some embodiments, if the number of stacked items is less than the preset number, the control of the first conveyor belt to transport the workpiece to the preset position is returned.

[0017] In some embodiments, the speed at which the pushing component moves the workpiece is negatively correlated with the number of stacked items.

[0018] In a second aspect, the present invention provides a universal joint bell-shaped cover tempering feeding device, applied to the universal joint bell-shaped cover tempering feeding method described in any one of the first aspects, wherein the universal joint bell-shaped cover tempering feeding device comprises:

[0019] A first conveying assembly includes a first conveyor belt and a first sensor; the first conveyor belt has a preset position; the first sensor is used to sense the working state of the preset position; the working state includes a material receiving state and an empty state.

[0020] The second conveying assembly includes a second conveyor belt, a positioning plate, an elastic plate, and a second sensor. The positioning plate and the elastic plate are laid along the length direction of the second conveyor belt. The length direction of the second conveyor belt forms an angle with the length direction of the first conveyor belt. There is a gap between the positioning plate and the elastic plate. The second sensor is fixedly connected to the second conveyor belt. The second sensor is used to detect the deformation of the elastic plate.

[0021] A pushing assembly is fixedly connected to the first conveyor belt; the piston rod of the pushing assembly extends and retracts parallel to the second conveyor belt; the piston rod of the pushing assembly is positioned toward the preset position; the piston rod of the pushing assembly extends and retracts between the elastic plate and the positioning plate.

[0022] A third conveying assembly, comprising a third conveyor belt; the conveying direction of the third conveyor belt forms an angle with the length direction of the second conveyor belt;

[0023] The tempering furnace, with a portion of the third conveyor belt located inside the tempering furnace and another portion located outside the tempering furnace.

[0024] In some embodiments, the pushing assembly includes a cylinder and a push plate; the push plate is fixedly connected to the piston rod of the cylinder; the cylinder pushes the push plate to move between the positioning plate and the elastic plate; in its natural state, the distance between the positioning plate and the elastic plate is greater than the width of the push plate; the width direction of the push plate is perpendicular to the sliding direction of the push plate.

[0025] In some embodiments, one end of the elastic plate near the third conveyor belt is a movable section, and the other end is a fixed section; the movable section can swing elastically; the fixed section is fixedly connected to the second conveyor belt; the second sensor is used to detect the swing of the movable section.

[0026] In some embodiments, the length of the second conveyor belt is greater than three times the dimension occupied by the workpiece in the length direction of the second conveyor belt;

[0027] The length of the active segment is greater than twice the length of the fixed segment;

[0028] The second conveying assembly further includes a pressure elastic element; one end of the pressure elastic element is fixedly connected to the second conveyor belt, and the other end is fixedly connected to the side of the movable section of the elastic plate opposite to the positioning plate.

[0029] To address the problem of the universal joint bell cover easily getting stuck during transport, leading to damage to the drive source, this invention has the following advantages:

[0030] The workpiece is transported to a preset position by controlling the first conveyor belt, and then the pushing component is controlled to move the workpiece along the second conveyor belt until it reaches the third conveyor belt. When the workpiece passes the second conveyor belt, the dwell time of the workpiece in the preset area of ​​the second conveyor belt is obtained. If the dwell time is longer than the preset time, the first conveyor belt, the pushing component and the third conveyor belt are controlled to stop working. This can prevent the tilted workpiece from moving with the conveyor belt to the side of the tempering furnace inlet and colliding, thereby avoiding the jamming of the third conveyor belt and ultimately solving the problem of the drive source being damaged due to overload.

[0036] In the actual operation of machining the ball cage universal joint shaft involving heat treatment, after the workpiece 60 arrives, it is pushed to the carrier belt by a telescopic cylinder, and then transported to the heat treatment tempering furnace 50 by the carrier belt. However, this can easily lead to excessive accumulation of workpiece 60 on the carrier belt. At the same time, under the pushing force of the telescopic cylinder or the vibration of the carrier belt, workpiece 60 may also be pushed over. The accumulated or tilted workpiece 60 will directly collide with the inlet side of the tempering furnace 50. On the one hand, this will hinder the normal operation trajectory of the carrier belt. On the other hand, the resistance generated by the collision will cause the carrier belt to jam. The continued jamming will further damage the drive source that drives the carrier belt due to overload.

[0037] Example 1:

[0038] Therefore, in order to solve the above problems, the present invention provides a method for tempering and feeding universal joint bell-shaped covers. The apparatus relating to the method for tempering and feeding universal joint bell-shaped covers includes a first conveying assembly 10, a second conveying assembly 20, a third conveying assembly 40, a pushing assembly 30, and a tempering furnace 50.

[0039] The first conveying assembly 10 includes a first conveyor belt 11 and a first sensor 13. The first conveyor belt 11 of the first conveying assembly 10 achieves the initial conveying of the workpiece 60, while the first sensor 13 accurately senses the incoming or unloaded state at a preset position. The second conveying assembly 20 includes a second conveyor belt 21, a positioning plate 22, an elastic plate 23, and a second sensor 24. A gap exists between the positioning plate 22 and the elastic plate 23, which can limit the movement of the workpiece 60. The second sensor 24 is used to detect the deformation of the elastic plate 23 to determine whether the workpiece 60 is tilting or jammed. The piston rod of the pushing assembly 30 extends and retracts between the elastic plate 23 and the positioning plate 22. The third conveying assembly 40 includes a third conveyor belt 41. The third conveyor belt 41 can smoothly receive the workpiece 60 conveyed by the second conveyor belt 21 and transfer the workpiece 60 to the tempering furnace 50.

[0040] In this embodiment, as Figure 1 As shown, the universal joint bell cover tempering feeding method includes steps S10 to S40, which will be described in detail below:

[0041] Step S10: Control the first conveyor belt 11 to accurately transport the workpiece 60 to the preset position, and use the first sensor 13 to detect the position of the workpiece 60 at the preset position to avoid positional deviation of the workpiece 60 during the transport stage, so as to ensure the accurate pushing of the subsequent push assembly 30 and the orderly start of the entire transport process. The workpiece 60 can be a universal joint bell-shaped cover.

[0042] In step S20, based on the workpiece 60 being located at a preset position, since the second conveyor belt 21 and the third conveyor belt 41 convey in opposite directions, the workpieces 60 are arranged in a row along the width direction of the third conveyor belt 41, with multiple workpieces per row, and the third conveyor belt 41 can carry multiple rows. If the second conveyor belt 21 is electrically powered, the friction of the second conveyor belt 21 would drive the workpieces 60 towards the third conveyor belt 41, preventing subsequent workpieces 60 from reaching the third conveyor belt 41. Therefore, the second conveyor belt 21 is configured without a power source, and instead, a pushing component 30, such as a cylinder 31, is used to push the workpieces 60 on the second conveyor belt 21. By controlling the pushing component 30, the workpieces 60 are moved along the second conveyor belt 21 until they reach the third conveyor belt 41. Since the workpieces 60 need to be pushed to the third conveyor belt 41 by the pushing component 30 after reaching the preset position, the pushing component 30 needs to extend and retract. To prevent the pushing component 30 from affecting other workpieces 60 on the first conveyor belt 11, the first conveyor belt 11 and the second conveyor belt 21 are at an angle. This allows the pushing component 30 to form a reasonable conveying path, facilitating the precise conveying of the workpieces 60. Preferably, the first conveyor belt 11 and the second conveyor belt 21 are perpendicular. Furthermore, the second conveyor belt 21 keeps the first conveyor belt 11 a certain distance from the tempering furnace 50.

[0043] Step S30: Based on the workpiece 60 passing through the second conveyor belt 21, obtain the dwell time of the workpiece 60 in the preset area of ​​the second conveyor belt 21. This can determine whether there is any abnormality in the workpiece 60 (such as tilting or jamming) and ensure effective monitoring of the workpiece 60 during the conveying process.

[0044] In step S40, based on the fact that the dwell time is longer than the preset time, it indicates that the workpiece 60 may tilt or get stuck. Therefore, the first conveyor belt 11, the push component 30 and the third conveyor belt 41 are controlled to stop working, thereby preventing the tilted workpiece 60 from moving with the conveyor belt to the subsequent work station and colliding with the equipment components, preventing the conveyor belt from getting stuck, and thus ensuring the stable operation of the entire device in conveying the workpiece 60.

[0045] In some embodiments, the universal joint bell-shaped cover tempering and feeding method further includes step S40. Step S40 includes steps S41 to S43. The universal joint bell-shaped cover tempering and feeding method executes steps S40, S10, S20, and S30 sequentially. Steps S41 to S43 will be described in detail below:

[0046] Step S41: Based on the workpiece 60 being located on the first conveyor belt 11, the status of the preset position is obtained, and it is known in advance whether the preset position is occupied by the workpiece 60, so as to provide a basis for judgment for the subsequent operation control of the first conveyor belt 11 and avoid blindly conveying the workpiece 60, which would cause the workpiece 60 to accumulate at the preset position.

[0047] Step S42: Based on the preset position being in an unloaded state, execute step S10. This ensures that workpiece 60 can accurately enter the preset position to await subsequent pushing, guaranteeing the continuity of the conveying process, and avoiding the workpiece 60 congestion problem caused by the need to continue conveying workpiece 60 even when there is one at the preset position.

[0048] Step S43: Based on the preset position being in the material receiving state (i.e., there is already a workpiece 60 at the preset position), the first conveyor belt 11 is controlled to stop. This prevents the first conveyor belt 11 from continuing to transport workpieces 60 to the preset position, avoiding the accumulation of workpieces 60 at the preset position from the source, further ensuring the orderly pushing of workpieces 60 by the subsequent pushing component 30, and ensuring the stability of the entire device in transporting workpieces 60.

[0049] In some embodiments, the universal joint bell-shaped cover tempering and feeding method further includes step S50. Step S50 includes steps S51 and S52. The universal joint bell-shaped cover tempering and feeding method executes steps S10, S20, S30, S51, and S52 sequentially. Steps S51 and S52 will be described in detail below:

[0050] In step S51, based on the fact that the dwell time is less than the preset time (i.e., when the workpiece 60 normally passes through the preset area of ​​the second conveyor belt 21), the cumulative accumulation number is incremented by 1. This can accurately count the number of workpieces 60 that are normally conveyed to the subsequent stages, providing a precise quantitative basis for the operation control of the third conveyor belt 41.

[0051] Step S52: Based on the accumulation reaching a preset quantity, the third conveyor belt 41 is controlled to convey the workpieces 60 a preset distance, ensuring timely transfer of the accumulated workpieces 60 along the set distance and preventing excessive accumulation of workpieces 60 on the third conveyor belt 41. The third conveyor belt 41 uses intermittent conveying, pausing for a period of time after each preset distance. The conveying direction of the third conveyor belt 41 forms an angle with the length direction of the second conveyor belt 21. This angled design allows more workpieces 60 to be fed into the tempering furnace 50 for heat treatment. If the third conveyor belt 41 and the second conveyor belt 21 were arranged parallel, only one row of workpieces 60 would enter the tempering furnace 50; the angled design allows for the conveying of multiple rows of workpieces 60. Furthermore, the square shape of the tempering furnace 50 allows for simultaneous heat treatment of multiple rows of workpieces 60 while saving space. This, combined with the conveying action, forms a reasonable transfer path, ensuring stable transfer of workpieces 60 and further guaranteeing the orderliness of the entire conveying process. Preferably, the length direction of the second conveyor belt 21 is perpendicular to the length direction of the third conveyor belt 41.

[0052] In some embodiments, the universal joint bell-shaped cover tempering and feeding method further includes step S60. The universal joint bell-shaped cover tempering and feeding method sequentially executes steps S10, S20, S30, S51, S52, and S60. Step S60 will be described in detail below:

[0053] In step S60, since the third conveyor belt 41 needs to move into the tempering furnace 50 after reaching the preset quantity, the accumulated quantity is reset to zero after the third conveyor belt 41 has transported the goods to the preset distance. This allows for timely reset of the accumulated quantity, ensuring accurate statistics on the newly transported accumulated quantity. This provides reliable data support for controlling the third conveyor belt 41 to transport the goods to the preset distance based on the accumulated quantity, avoiding errors in the operation control of the third conveyor belt 41 due to statistical deviations in the accumulated quantity. This further ensures the orderly accumulation and transfer of workpieces 60 on the third conveyor belt 41, maintaining the stable operation of the entire device.

[0054] In some embodiments, the universal joint bell-shaped cover tempering and feeding method further includes step S70. The universal joint bell-shaped cover tempering and feeding method sequentially executes steps S10, S20, S30, S51, S52, and S70. Step S70 will be described in detail below:

[0055] In step S70, based on the fact that the accumulated quantity is less than a preset quantity, the execution control returns to the first conveyor belt 11 to transport the workpiece 60 to the preset position, ensuring that the workpiece 60 continuously and orderly enters the second conveyor belt 21, and the number of transported workpieces 60 is accumulated before being transported to the third conveyor belt 41. This ensures that the third conveyor belt 41 moves only after it has a sufficient quantity, which can improve the efficiency of transporting workpieces 60 for heat treatment.

[0056] Furthermore, the moving speed of the push component 30 pushing the workpiece 60 is negatively correlated with the number of stacked items. By making the pushing speed of the push component 30 decrease as the number of stacked items increases and increase as the number of stacked items decreases, the pushing rhythm can be dynamically adjusted according to the actual stacking situation of the workpieces 60. When the number of stacked items is large, reducing the pushing speed can avoid large impact forces between the subsequent workpieces 60 and the workpieces 60 on the third conveyor belt 41, thus avoiding damage to the workpieces 60. At the same time, it can avoid the momentary resistance of the push component 30 being large when the workpieces 60 behind collide with the workpieces 60 in front, which could damage the push component 30. When the number of stacked items is small, increasing the pushing speed can speed up the conveying efficiency of the workpieces 60, thereby ensuring conveying efficiency while effectively avoiding excessively fast conveying speed of the workpieces 60, which could lead to large impact forces with the workpieces 60 stacked in the third conveyor belt 41, further maintaining the stable operation of the entire conveying system.

[0057] Example 2:

[0058] In this embodiment, as Figure 2 As shown, the universal joint bell-shaped hood tempering feeding device includes a first conveying component 10, a second conveying component 20, a third conveying component 40, a pushing component 30, and a tempering furnace 50.

[0059] The first conveying assembly 10 includes a first conveyor belt 11 and a first sensor 13. The first conveyor belt 11 has a preset position. The first sensor 13 is used to sense the working state of the preset position. The working state includes a material receiving state and an empty state. The first conveyor belt 11 of the first conveying assembly 10 realizes the initial conveying of the workpiece 60. The first sensor 13 accurately senses the material receiving state or the empty state of the preset position, providing accurate information for subsequent control of starting and stopping the first conveyor belt 11, preventing the accumulation of workpieces 60 at the preset position, and ensuring the orderliness and safety of the initial conveying of the workpieces 60.

[0060] The second conveying assembly 20 includes a second conveyor belt 21, a positioning plate 22, an elastic plate 23, and a second sensor 24. The positioning plate 22 and the elastic plate 23 are laid along the length of the second conveyor belt 21. The length of the second conveyor belt 21 forms an angle with the length of the first conveyor belt 11, receiving the workpiece 60 conveyed by the first conveyor belt 11 and forming a reasonable conveying path. A gap exists between the positioning plate 22 and the elastic plate 23, allowing the workpiece 60 to move within this gap, thus limiting its movement. The second sensor 24 is fixedly connected to the second conveyor belt 21. The second sensor 24 detects the deformation of the elastic plate 23, determining whether the workpiece 60 is tilting or jammed. If the dwell time is too long, the operation of the universal joint bell-shaped cover tempering feeding device is stopped to prevent abnormal conveying of the workpiece 60 (workpiece 60 jamming and damage to the device, device damage). Simultaneously, it indirectly accumulates the number of workpieces 60 conveyed, providing a reference for the movement of the third conveying assembly 40.

[0061] The push assembly 30 is fixedly connected to the first conveyor belt 11. The piston rod of the push assembly 30 extends and retracts parallel to the second conveyor belt 21. The piston rod of the push assembly 30 is set towards a preset position and extends and retracts between the elastic plate 23 and the positioning plate 22. This accurately pushes the workpiece 60 at the preset position between the positioning plate 22 and the elastic plate 23 of the second conveyor belt 21, ensuring that the workpiece 60 moves stably along the second conveyor belt 21 and avoiding pushing deviation that could cause the workpiece 60 to tip over or accumulate, thus ensuring the stability of the workpiece 60 during the conveying process.

[0062] The third conveying assembly 40 includes a third conveyor belt 41. The conveying direction of the third conveyor belt 41 forms an angle with the length direction of the second conveyor belt 21. This allows it to smoothly receive the workpieces 60 conveyed by the second conveyor belt 21 and transfer them to the tempering furnace 50, forming a continuous feeding path and preventing jamming of the workpieces 60 during transfer, ensuring a smooth feeding process. Simultaneously, the angled design between the conveying direction of the third conveyor belt 41 and the length direction of the second conveyor belt 21 adapts to the shape of the tempering furnace 50, allowing the third conveying assembly 40 to convey a maximum number of workpieces 60 to the tempering furnace 50 for heat treatment, thus improving the processing efficiency of the workpieces 60. Preferably, the conveying direction of the third conveyor belt 41 is perpendicular to the length direction of the second conveyor belt 21.

[0063] Part of the third conveyor belt 41 is located inside the tempering furnace 50, and the other part is located outside the tempering furnace 50. This allows the workpiece 60 on the third conveyor belt 41 to directly enter the tempering furnace 50 for heat treatment without additional transfer steps, reducing the loss and delay during the transfer of the workpiece 60. At the same time, it facilitates the removal of the workpiece 60 from the tempering furnace 50 after subsequent processing, ensuring efficient connection between the heat treatment process and the feeding process.

[0064] In other embodiments, the third conveying assembly 40 further includes partitions 42 arranged in an array and fixedly connected to the third conveyor belt 41. These partitions are used to block multiple rows of workpieces 60.

[0065] The first conveying assembly 10 also includes a blocking part 12, which is located at the end of a preset position on the first conveyor belt 11. The blocking part 12 can prevent the workpiece 60 from moving too far from the conveying position and falling to the ground. Thus, the blocking part 12 enables the workpiece 60 to be accurately conveyed to the preset position on the first conveyor belt 11.

[0066] Furthermore, such as Figure 2 As shown, the pushing assembly 30 includes a cylinder 31 and a pusher plate 32. The pusher plate 32 is fixedly connected to the piston rod of the cylinder 31. Power is provided by the cylinder 31 to drive the pusher plate 32, which is fixedly connected to the piston rod, to move. This provides a stable driving force for the pusher plate 32 to push the workpiece 60, ensuring that the pusher plate 32 reliably pushes the workpiece 60 along the set direction and avoids pushing failure due to insufficient power or loose connection. At the same time, the use of the pusher plate 32 can increase the contact area with the workpiece 60 and improve the stability of conveying the workpiece 60. The cylinder 31 pushes the pusher plate 32 to move between the positioning plate 22 and the elastic plate 23, ensuring that the pusher plate 32 always moves along the preset trajectory (along the length direction of the second conveying assembly 20) and preventing the pusher plate 32 from deviating and causing the workpiece 60 to be pushed in a deviated position. In its natural state, the distance between the positioning plate 22 and the elastic plate 23 is greater than the width of the pusher plate 32, and the width direction of the pusher plate 32 is perpendicular to the sliding direction of the pusher plate 32. This provides ample space for the push plate 32 to move between the two, avoiding friction or collision between the push plate 32 and the positioning plate 22 or the elastic plate 23 when the push plate 32 moves, reducing wear on the push plate 32 and the elastic plate 23 and positioning plate 22, extending the service life of the components, and ensuring the smooth movement of the push plate 32.

[0067] Furthermore, such as Figure 2 As shown, the elastic plate 23 has a movable section 232 at one end near the third conveyor belt 41 and a fixed section 231 at the other end. The fixed section 231 is fixedly connected to the second conveyor belt 21, providing a stable mounting base for the elastic plate 23. This allows the movable section 232 to swing elastically, ensuring that the elastic plate 23 and the positioning plate 22 can limit the transport of the workpiece 60. The deformation of the elastic plate 23 also allows the second sensor 24 to detect the number and status of the workpiece 60 passing through the second conveyor belt 21 (whether it tilts or jams), ensuring effective capture of the workpiece 60's status. Furthermore, the number of workpieces 60 transported to the third conveyor belt 41 can be accumulated, and the third conveyor belt 41 will then transport the workpiece 60 to the tempering furnace 50 for heat treatment.

[0068] Furthermore, such as Figure 2As shown, the length of the second conveyor belt 21 is greater than three times the dimension occupied by the workpiece 60 along the length of the second conveyor belt 21. This provides sufficient space for multiple workpieces 60 to be conveyed sequentially on the second conveyor belt 21, avoiding the workpieces 60 from being squeezed and piled up due to insufficient conveyor belt length, and ensuring the orderly conveying of the workpieces 60 on the second conveyor belt 21.

[0069] The length of the movable segment 232 is more than twice the length of the fixed segment 231, which allows the movable segment 232 to have a larger swing space and a more obvious deformation amplitude. This makes it easier for the second sensor 24 to detect the swing of the movable segment 232 more clearly, improves the accuracy of judging the state of the workpiece 60, and avoids detection errors caused by the inconspicuous swing of the movable segment 232.

[0070] The second conveying assembly 20 also includes a pressure elastic element 25. One end of the pressure elastic element 25 is fixedly connected to the second conveyor belt 21, and the other end is fixedly connected to the side of the movable section 232 of the elastic plate 23 facing away from the positioning plate 22. The pressure elastic element 25 provides a reverse elastic force when the movable section 232 of the elastic plate 23 swings away from the positioning plate 22 under the pressure of the workpiece 60, assisting the movable section 232 to quickly reset after the workpiece 60 passes, ensuring that the status detection of the next workpiece 60 is not affected and maintaining the continuity of detection. At the moment when the workpiece 60 just reaches the end of the movable section 232 near the fixed section 231, the movable section 232, due to its long distance, experiences smaller deformation near the fixed section 231, but a larger swing amplitude in the part away from the fixed section 231, which is prone to collision with the second sensor 24. The pressure elastic element 25 can prevent this phenomenon, thereby preventing the swing amplitude of the movable section 232 from exceeding the limit and ensuring that the elastic plate 23 deforms within a safe range.

[0071] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
