Abstract

This invention relates to a pick-and-place machine, comprising a machine body and a feeder cart. The machine body is provided with positioning holes and floating holes at intervals, and the machine body has a docking interface. The feeder cart includes a body and a first positioning post, a second positioning post, and a communication interface disposed on the body. The first positioning post and the second positioning post are spaced apart, and the first positioning post matches the positioning hole. During the docking of the feeder cart to the machine body, the first positioning post slides with the positioning hole, and the second positioning post floats with the floating hole, so that the communication interface docks with the docking interface. The first positioning post and the positioning hole can be machined to obtain relatively high fitting accuracy, ensuring that the communication interface and the docking interface are basically aligned. The floating fit of the second positioning post and the floating hole provides suitable floating space, preventing jamming problems caused by small engineering errors during docking. This allows the feeder cart to dock smoothly to the pick-and-place machine and reduces the machining difficulty of the docking structure between the feeder cart and the machine body.

Description

Technical Field

[0001] This invention relates to the field of chip mounting technology, and in particular to a chip mounting machine. Background Technology

[0002] Automated pick-and-place machines are devices used to place electronic components at high speed and with high precision. They are the most critical and complex equipment in the entire SMT (Surface Mount Technology) production process. In related technologies, pick-and-place machines can use feeder carts for loading components. The feeder and the roll of material tape are loaded onto the feeder cart, and the feeder guides the surface mount components on the tape to the head of the pick-and-place machine during the placement process. The feeder cart usually also needs to be equipped with a communication interface to enable communication between the feeder and the pick-and-place machine's control system after the feeder cart is installed on the machine.

[0003] To ensure accurate docking between the communication interface and the machine body, the positional accuracy requirements for the docking structure between the feeder car and the machine body are high, but the high positional accuracy requirements will increase the processing difficulty of the docking structure. Summary of the Invention

[0004] This invention provides a chip mounter to reduce the processing difficulty of the feeder cart docking structure with the machine body.

[0005] A pick and place machine, comprising:

[0006] The body has positioning holes and floating holes spaced apart, and the body is equipped with a docking interface; and

[0007] The feeder cart includes a body and a first positioning post, a second positioning post, and a communication interface disposed on the body. The first positioning post and the second positioning post are spaced apart, and the first positioning post matches the positioning hole. During the process of the feeder cart docking with the machine body, the first positioning post slides with the positioning hole, and the second positioning post floats with the floating hole, so that the communication interface docks with the docking interface.

[0008] In one embodiment, the feeder cart has a first direction, a second direction, and a docking direction that are perpendicular to each other. The feeder cart docks to the machine body along the docking direction. The second direction has a plurality of mounting slots for installing feeders. The first positioning post and the second positioning post are arranged at intervals along the second direction, and the second positioning post and the floating hole float in the first direction.

[0009] In one embodiment, the first positioning post includes an integrally formed first guide portion and a first positioning portion. The first positioning portion has a conical surface for sliding contact with the wall of the positioning hole, and the diameter of the first positioning portion matches the diameter of the positioning hole. The second positioning post includes an integrally formed second guide portion and a second positioning portion. The second positioning portion has a conical surface for sliding contact with the wall of the floating hole. The width of the second positioning portion in the second direction matches the width of the floating hole in the second direction, and the height of the second positioning portion in the first direction is less than the height of the floating hole in the first direction.

[0010] In one embodiment, the feeder cart includes two third positioning posts disposed on the body, the two third positioning posts being spaced apart in the second direction, and the third positioning posts being spaced apart from the first positioning post and the second positioning post in the first direction; the machine body is provided with two guide holes, the two guide holes corresponding one-to-one with the two third positioning posts; during the process of the feeder cart docking with the machine body, the two third positioning posts cooperate with the machine body before the first positioning post and the second positioning post.

[0011] In one embodiment, the patching machine includes a first detection component and a second detection component disposed on the machine body and used to detect the feeder. The first detection component includes a first transmitter and a first receiver spaced apart and correspondingly disposed in the second direction. The second detection component includes a second transmitter and a second receiver spaced apart and correspondingly disposed in the second direction. The first transmitter and the second receiver are disposed on one side of the vehicle body, and the first receiver and the second transmitter are disposed on the opposite side of the vehicle body.

[0012] In one embodiment, the feeder includes a mounting bracket and a cover, the cover having a first end and a second end opposite to each other, the first end being rotatably connected to the mounting bracket, and the second end being detachably fastened to the mounting bracket; in the mating direction, the first detection component is further away from the second end than the second detection component, and the second detection component detects an angle at which the cover is lifted relative to the mounting bracket less than the angle at which the cover is lifted relative to the mounting bracket detected by the first detection component.

[0013] In one embodiment, the machine body includes a baffle bar fixed relative to the position of the positioning hole, and the feeder cart includes a movable plate movably fitted to the machine body. The machine body has a recycling channel for guiding the waste belt. During the process of the feeder cart docking with the machine body, the baffle bar abuts against the movable plate to drive the movable plate to move relative to the machine body. After the feeder cart is docked with the machine body, the movable plate returns to its original position to close the gap between the recycling channel and the baffle bar.

[0014] In one embodiment, the movable plate includes an integrally formed sliding part and a stop part, the sliding part and the stop part being arranged at an angle, and the sliding part being slidably engaged with the vehicle body; during the process of the feeder car docking with the machine body, the connection part of the sliding part and the stop part abuts against the material stop bar to drive the sliding part to move relative to the vehicle body; when the feeder car is docked with the machine body, the movable plate moves back to its original position under the action of gravity.

[0015] In one embodiment, the end of the baffle bar facing away from the recycling channel has a guide portion, the guide portion extends along the docking direction and has a guide slope, the guide slope is inclined relative to the docking direction, and during the process of the feeder car docking to the machine body, the connection part of the sliding part and the stop part abuts against the guide slope.

[0016] In one embodiment, the pick-and-place machine includes a moving mechanism and at least two clamping mechanisms. The moving mechanism is fixedly connected to the machine body, and the two clamping mechanisms are arranged at intervals in the second direction. Each clamping mechanism includes a driver fixedly connected to the output end of the moving mechanism and a clamping block linked to the output end of the driver. The feeder cart includes a crossbar connected to the machine body and extending along the second direction. During the process of the feeder cart docking with the machine body, after the crossbar passes the clamping block, the clamping mechanism drives the clamping block to rotate to restrict the crossbar from disengaging from the machine body along the docking direction. The moving mechanism drives the feeder cart to dock with the machine body along the docking direction.

[0017] The above-mentioned pick-and-place machine includes a machine body and a feeder cart. The machine body is equipped with positioning holes and floating holes at intervals, and has a docking interface. The feeder cart includes a body and a first positioning post, a second positioning post, and a communication interface located on the body. The first and second positioning posts are spaced apart, and the first positioning post matches the positioning hole. During the docking process of the feeder cart to the machine body, the first positioning post slides with the positioning hole, and the second positioning post floats with the floating hole, so that the communication interface docks with the docking interface. The sliding engagement of the first positioning post and the positioning hole, and the floating engagement of the second positioning post and the floating hole, can effectively limit the spatial freedom of the feeder cart and ensure the reliability of the feeder cart's positioning within the machine body. The first positioning post and the positioning hole can be machined to achieve relatively high fitting accuracy, ensuring that the communication interface and the docking interface are basically aligned. The floating engagement of the second positioning post and the floating hole provides suitable floating space, preventing jamming problems caused by small engineering errors during docking. This allows the feeder cart to dock smoothly to the machine body and reduces the machining difficulty of the docking structure between the feeder cart and the machine body.

Detailed Implementation

[0033] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the accompanying drawings. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present disclosure.

[0034] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] refer to Figure 1 This invention discloses a pick-and-place machine 100, which can be used to mount surface mount components onto a circuit board. In some embodiments, the surface mount components for mounting are disposed on a flexible tape wound into a disc shape, and the surface mount components are distributed along the tape. See also... Figure 2 The pick-and-place machine 100 includes a machine body 10 and a feeder cart 20. The machine body 10 may include an electrical control module and a head (not shown). The electrical control module is used to control the operation of the entire pick-and-place machine 100. Reels of tape are mounted on the feeder cart 20 and pass through a feeder 30 (see reference) on the feeder cart 20. Figure 7 The feeder 30 conveys surface mount components to the feeder head, which then retrieves the components from the feeder and attaches them to the circuit board. Specifically, the feeder 30 may be equipped with a power mechanism, such as a motor or gear transmission mechanism, which pulls the conveyor belt to the feeder head, sequentially exposing the surface mount components attached to the conveyor belt to the feeder head for easy retrieval. The conveyor belt after removing the surface mount components becomes waste belt and can be recycled to prevent environmental pollution.

[0037] refer to Figure 2 and combined Figure 3 , Figure 4 and Figure 5 The body 10 of the pick-and-place machine 100 is provided with positioning holes 10a and floating holes 10b at intervals, and the body 10 is provided with a docking interface 10c. The feeder cart 20 is detachably mounted to the body 10 and includes a body 21 and a first positioning post 22, a second positioning post 23, and a communication interface 24 located on the body 21. The first positioning post 22 and the second positioning post 23 are spaced apart, and the first positioning post 22 mates with the positioning hole 10a. During the docking of the feeder cart 20 to the body 10, the first positioning post 22 slides with the positioning hole 10a, and the second positioning post 23 floats with the floating hole 10b, so that the communication interface 24 docks with the docking interface 10c. The body 21 can also be configured with corresponding control circuitry, and after the body 21 is mounted to the body 10 of the pick-and-place machine 100, communication connection with the body 10 is achieved through the communication interface 24 and the docking interface 10c.

[0038] refer to Figure 6The feeder cart 20 has two perpendicular directions: a first direction, a second direction, and a docking direction. The feeder cart 20 docks with the machine body 10 along the docking direction. In other words, after the operator pushes the feeder cart 20 to a preset position on the machine body 10, they continue to push the feeder cart 20 along the docking direction, and the feeder cart 20 is installed on the machine body 10, realizing the docking of the feeder cart 20 with the machine body 10, enabling the feeder 30 to communicate with the electrical control module of the pick-and-place machine 100. The second direction of the feeder cart 20 can be arranged with multiple mounting slots 20a for mounting the feeder 30, each mounting slot 20a for detachably mounting the feeder 30. After the feeder 30 is installed in the mounting slot 20a, the feeder 30 and the feeder cart 20 are in communication connection.

[0039] Combination Figure 5 In some embodiments, the communication interface 24 includes multiple floating terminals, which may adopt a pogo-pin structure and can be arranged in an array on the body 21. Correspondingly, the docking interface 10c of the body 10 may include multiple conductive pads, each corresponding to a floating terminal, to enable communication between the feeder cart 20 and the electrical control module of the pick-and-place machine 100 after the feeder cart 20 docks with the body 10 of the pick-and-place machine 100. This, in turn, enables communication between the electrical control module of the pick-and-place machine 100 and the feeder 30 to control the operating status of the feeder 30. By using floating terminals in conjunction with conductive pads, the conductive pads can have a relatively large contact area, providing a certain floating space for the floating terminals. This ensures that the fit error requirement between the floating terminals and the docking interface 10c is not too high, reducing the positional accuracy requirements for processing and assembly while guaranteeing the reliability of the communication connection between the feeder cart 20 and the electrical control module of the pick-and-place machine 100 after docking.

[0040] The frame of the feeder cart 20's body 21 can be formed by welding sheet metal, providing rigid support for the entire feeder cart 20. The feeder cart 20 may also include rollers 25 rotatably connected to the body 21. Four or more rollers 25 can be provided and can be used to roll on a support surface, such as the ground, reducing the resistance of the body 21's movement on the ground and facilitating the operator's movement of the feeder cart 20, for example, removing the feeder cart 20 from the body 10 of the pick-and-place machine 100 to replace the feeder 30. Alternatively, it facilitates the operator's movement and installation of the feeder cart 20 after replacing the feeder 30 onto the body 10 of the pick-and-place machine 100.

[0041] The first positioning post 22 and the second positioning post 23 are arranged at intervals along the second direction, and the second positioning post 23 floats and engages with the floating hole 10b in the first direction. Specifically, refer to... Figure 3The first positioning post 22 includes an integrally formed first guide portion 221 and a first positioning portion 223. The first positioning portion 223 is approximately cylindrical, and its diameter matches the diameter of the positioning hole 10a, or in other words, the diameter of the first positioning portion 223 is equivalent to the diameter of the positioning hole 10a, or, considering engineering errors, the diameter of the first positioning portion 223 is equal to the diameter of the positioning hole 10a. The first guide portion 221 has a conical surface for sliding contact with the wall of the positioning hole 10a, that is, the first guide portion 221 is conical, and the diameter of the cone gradually increases from the end away from the first positioning portion 223 toward the first positioning portion 223.

[0042] refer to Figure 4 The second positioning post 23 includes an integrally formed second guide portion 231 and a second positioning portion 233. The second positioning portion 233 is approximately cylindrical, and its diameter can be equal to the diameter of the first positioning portion 223, taking into account engineering errors. The second guide portion 231 has a conical surface for sliding contact with the wall of the floating hole 10b; that is, the second guide portion 231 is conical, and the diameter of the cone gradually increases from the end away from the second positioning portion 233 toward the second positioning portion 233. The width of the second positioning portion 233 in the second direction matches the width of the floating hole 10b in the second direction, or in other words, the width of the second positioning portion 233 in the second direction is equal to the width of the floating hole 10b in the second direction, taking into account engineering errors. The height of the second positioning portion 233 in the first direction is less than the height of the floating hole 10b in the first direction.

[0043] During the docking process of feeder cart 20 to body 10, the engagement of the first positioning post 22 with positioning hole 10a and the engagement of the second positioning post 23 with floating hole 10b can occur almost simultaneously. That is, the ends of the first positioning post 22 and the second positioning post 23 can be located on a straight line extending along the second direction. In the initial stage of docking, the first guide part 221 enters the positioning hole 10a. The engagement of the conical surface of the first guide part 221 with the positioning hole 10a can prevent the feeder cart 20 from having a rigid collision with the periphery of the first positioning post 22 and the positioning hole 10a due to displacement error. With the centering and error-proofing effect of the conical surface, the feeder cart 20 can be moved to the preset position. Similarly, in the initial stage of docking, the second guide part 231 enters the floating hole 10b. The conical surface of the second guide part 231 cooperates with the floating hole 10b, which can also prevent the feeder cart 20 from having a rigid collision with the periphery of the floating hole 10b due to displacement error. With the centering and error-proofing effect of the conical surface, the feeder cart 20 can be moved to the preset position.

[0044] By ensuring the machining accuracy of the first positioning post 22 and the positioning hole 10a, the movement freedom of the feeder cart 20 in the first and second directions can be restricted, thereby initially ensuring the alignment of the communication interface 24 and the docking interface 10c in the first and second directions. Combined with the limiting of the second positioning post 23 and the floating hole 10b in the second direction, and limiting the floating range of the second positioning post 23 and the floating hole 10b in the first direction to a certain range (for example, floating up and down in the first direction less than 0.5mm), the rotational freedom of the feeder cart 20 around the docking direction can be limited to a suitable range, preventing the floating terminal and the corresponding conductive disk from being too far off-center, thereby ensuring the docking accuracy of the communication interface 24 and the docking interface 10c, and preventing collision damage to the communication interface 24 during the docking process.

[0045] Compared to the scheme where the second positioning post 23 and the body 10 are fitted in a similar way to the first positioning post 22 and the positioning hole 10a, ensuring the fitting accuracy of the first positioning post 22 and the positioning hole 10a during the docking process, and ensuring the fitting accuracy of the second positioning post 23 and the body 10, places extremely high machining accuracy requirements on the mating structure of the second positioning post 23 and the body 10. This high machining accuracy requirement not only reduces the yield rate, but may also cause difficulties in docking the feeder cart 20 and the body 10 due to factors such as deformation errors in the body 21 structure, damaging the docking structure and leading to poor communication. By using the fitting of the second positioning post 23 and the floating hole 10b, the machining positional accuracy requirements of the mating structure of the second positioning post 23 and the body 10 can be reduced. While ensuring the limiting reliability of the feeder cart 20, it prevents small engineering errors from causing jamming problems during docking, allowing the feeder cart 20 to successfully dock to the pick-and-place machine 100, and reducing the machining difficulty of the docking structure between the feeder cart 20 and the body 10.

[0046] Further, refer to Figure 3 and Figure 4 In some embodiments, the second positioning part 233 may have flat cut surfaces 2331 on both sides of the first direction, that is, the opposite sides of the second positioning part 233 in the first direction are machined into planes, so that the cross-section of the second positioning part 233 is approximately racetrack-shaped. This reduces the amount of material removed from the floating hole 10b on the opposite sides of the first direction, reduces the machining difficulty of the floating hole 10b, and ensures that the floating range of the second positioning post 23 and the floating hole 10b is within a preset range, ensuring smooth docking between the communication interface 24 and the docking interface 10c. Of course, the opposite sides of the first positioning post 22 in the first direction can also be machined into planes to reduce the machining difficulty of the positioning hole 10a and ensure smooth docking between the first positioning post 22 and the positioning hole 10a.

[0047] Simultaneously combined Figure 2 , Figure 5In some embodiments, the feeder cart 20 includes two third positioning posts 26 disposed on the body 21. The two third positioning posts 26 are spaced apart in a second direction, and are spaced apart from the first positioning posts 22 and the second positioning posts 23 in the first direction. The machine body 10 is provided with two guide holes (not shown), which correspond one-to-one with the two third positioning posts 26. During the docking process of the feeder cart 20 to the machine body 10, the two third positioning posts 26 engage with the machine body 10 before the first positioning posts 22 and the second positioning posts 23. The shape of the third positioning posts 26 is similar to that of the first positioning posts 22; their front end can be conical, and their rear end can be cylindrical. The guide holes of the machine body 10 can be circular holes, but the machining accuracy of the guide holes and the third positioning posts 26 can be appropriately reduced, for example, the diameter of the guide holes can be larger than that of the third positioning posts 26. The third positioning post 26 engages with the body 10 before the first positioning post 22 and the second positioning post 23. It guides the alignment of the first positioning post 22 with the positioning hole 10a and the second positioning post 23 with the floating hole 10b. The third positioning post 26 can have a larger diameter and a longer length in the docking direction than the first positioning post 22 and the second positioning post 23 to achieve better structural rigidity. During the insertion into the guide hole, a longer guide path is provided to guide the first positioning post 22, the second positioning post 23, and the communication interface 24 to the correct docking position. First, the third positioning post 26 is used to guide the guide hole for a less precise fit. Then, the first positioning post 22 and the second positioning post 23 are used for a more precise docking process. This prevents the first positioning post 22 and the second positioning post 23 from rigidly impacting the machine body 10, and also prevents the communication interface 24 from rigidly impacting the machine body 10. This also prevents the feeder cart 20 from getting stuck during docking with the machine body 10, ensuring smooth docking and reliable docking between the communication interface 24 and the interface 10c.

[0048] refer to Figure 6 The pick-and-place machine 100 includes a moving mechanism (not shown) and at least two clamping mechanisms 40. The moving mechanism is fixedly connected to the machine body 10 and can be a hydraulic cylinder or a pneumatic cylinder. The two clamping mechanisms 40 are arranged at intervals in a second direction. Each clamping mechanism 40 includes a driver 41 fixedly connected to the output end of the moving mechanism and a clamping block 43 linked to the output end of the driver 41. The driver 41 can be a hydraulic cylinder or a pneumatic cylinder. The feeder cart 20 includes a crossbar 27 connected to the body 21 and extending in a second direction. During the docking of the feeder cart 20 to the machine body 10, after the crossbar 27 passes the clamping block 43, the driver 41 of the clamping mechanism 40 drives the clamping block 43 to rotate to restrict the crossbar 27 from disengaging from the machine body 10 in the docking direction. The moving mechanism then drives the feeder cart 20 to dock with the machine body 10 in the docking direction.

[0049] The machine body 10 can also be equipped with a guide channel and a position sensor, while the body 21 can be equipped with guide wheels that slide with the guide channel to facilitate the operator pushing the feeder cart 20 into the guide channel. When the operator pushes the feeder cart 20 a certain distance towards the machine body 10, the position sensor, such as a light sensor or a pressure sensor, can detect the position of the body 21, thereby activating the clamping mechanism 40, causing the clamping block 43 to rotate. Then, the moving mechanism pulls the clamping mechanism 40 towards the machine body 10, and the clamping block 43 pulls the third positioning post 26 of the feeder cart 20 to align with the guide hole. The first positioning post 22 then aligns with the positioning hole 10a, and the second positioning post 23 aligns with the floating hole 10b, thus achieving smooth alignment between the feeder cart 20 and the machine body 10. The moving mechanism and the clamping mechanism 40 can achieve automatic alignment between the feeder cart 20 and the machine body 10 after the feeder cart 20 is pushed to a certain position, improving the convenience of the alignment operation.

[0050] refer to Figure 7 In some embodiments, the pick-and-place machine 100 includes a first detection component 51 and a second detection component 53 disposed on the machine body 10 and used for detecting the feeder 30. The first detection component 51 includes a first transmitting end 511 and a first receiving end 513 spaced apart and correspondingly arranged in a second direction. The second detection component 53 includes a second transmitting end 531 and a second receiving end 533 spaced apart and correspondingly arranged in a second direction. The first transmitting end 511 and the second receiving end 533 are disposed on one side of the body 21, and the first receiving end 513 and the second transmitting end 531 are disposed on the opposite side of the body 21. The first detection component 51 can be a photoelectric sensor, in which the first transmitting end 511 emits light and the second receiving end 533 receives the light. If the light emitted by the first transmitting end 511 is blocked, it indicates that there is an obstacle between the first transmitting end 511 and the first receiving end 513, thereby realizing the detection function. The second detection component 53 can also be a photoelectric sensor, and its principle is similar to that of the first detection component 51.

[0051] Specifically, refer to Figure 8 The feeder 30 includes a mounting frame 31 and a cover 33. The mounting frame 31 can be equipped with a power mechanism such as a motor or transmission gear to pull the material belt from the material tray to the machine head. After the surface mount components on the material belt are removed by the machine head, it guides the recycling of waste material belt in a timely manner to prevent interference with the normal feeding of surface mount components. The cover 33 has a first end 331 and a second end 333. The first end 331 is rotatably connected to the mounting frame 31, and the second end 333 is used to detachably fasten to the mounting frame 31. In the mating direction, the first detection component 51 is further away from the second end 333 than the second detection component 53, and the angle at which the second detection component 53 detects the cover 33 being lifted relative to the mounting frame 31 is smaller than the angle at which the first detection component 51 detects the cover 33 being lifted relative to the mounting frame 31.

[0052] The cover 33 has a window 335 for exposing surface mount components. After the feeder 30 is installed on the feeder cart 20, the cover 33 can be opened to pull the front end of the material strip from the tray to the window 335 of the cover 33; after the cover 33 is fastened to the mounting bracket 31, the feeder cart 20 is docked to the body 21, and the feeder 30 is used for loading. Since one end of the cover 33 is detachably fastened to the mounting bracket 31, it is possible for it to accidentally detach from the mounting bracket 31. The first detection component 51 and the second detection component 53 are used to detect the state of the cover 33, and the electrical control module of the pick-and-place machine 100 can then determine whether the cover 33 of the feeder 30 is in the normal position based on the detection results. When the end of the pressure cap 33 that is fastened to the mounting bracket 31 comes off the mounting bracket 31 and forms a small angle with the mounting bracket 31, the pressure cap 33 blocks the optical path of the second detection component 53. The pick-and-place machine 100 responds to this detection signal by alarming and stopping, or by stopping the operation of the feeder cart 20, which is convenient for the operator to perform maintenance. When the end of the pressure cap 33 that is fastened to the mounting bracket 31 comes off the mounting bracket 31 and forms a larger angle with the mounting bracket 31, the detection optical path of the second detection component 53 is no longer blocked by the pressure cap 33, but the pressure cap 33 will block the optical path of the first detection component 51. The pick-and-place machine 100 can also respond to this detection signal by alarming and stopping, or by stopping the operation of the feeder cart 20, which is convenient for the operator to perform maintenance. In other words, the cooperation of the first detection component 51 and the second detection component 53 can detect both the small and large angles at which the cover 33 is lifted relative to the mounting bracket 31. That is, the range of angles at which the cover 33 is lifted relative to the mounting bracket 31 is larger than that of a single detection component, thereby providing timely alarms and preventing damage to the nose or other mechanisms caused by the feeder 30 operating in an abnormal state.

[0053] Since the first transmitter 511 and the second receiver 533 are located on one side of the vehicle body 21, and the first receiver 513 and the second transmitter 531 are located on the opposite side of the vehicle body 21, the light emitted by the first transmitter 511 will not reach the second receiver 533 due to accidental vibration or scattering of the fuselage 10 or the vehicle body 21, thus preventing the second detection component 53 from missing a detection. Similarly, the light emitted by the second transmitter 531 will not reach the first receiver 513 due to accidental vibration or scattering of the fuselage 10 or the vehicle body 21, thus preventing the first detection component 51 from missing a detection. Therefore, the above arrangement can prevent interference between the first detection component 51 and the second detection component 53, thus ensuring the reliability of the detection.

[0054] refer to Figure 9 , Figure 10 , Figure 11 and Figure 12The body 10 includes a baffle strip 11 fixed relative to the position of the positioning hole 10a, the baffle strip 11 spanning the body 21 in a second direction. The feeder cart 20 includes a movable plate 28 movably fitted to the body 21, the movable plate 28 extending from one side of the body 21 to the opposite side in a second direction. The body 21 has a recycling channel 21a for guiding the waste strip, the recycling channel 21a extending from one side of the body 21 to the opposite side in a second direction, such that all feeders 30 mounted on the body 21 can recover the waste strip from the recycling channel 21a. (Reference) Figure 9 and Figure 10 During the process of feeder car 20 docking with machine body 10, the baffle bar 11 abuts against movable plate 28 to drive movable plate 28 to move relative to machine body 21; Reference Figure 11 and Figure 12 When the feeder trolley 20 is docked in place with the machine body 10, the movable plate 28 returns to its original position to close the gap between the recycling channel 21a and the baffle bar 11.

[0055] Specifically, the movable plate 28 extends in the second direction and its cross-section may be L-shaped, including a sliding portion 281 and a stopping portion 283. The sliding portion 281 and the stopping portion 283 correspond to the two sides of the L-shape, that is, the sliding portion 281 and the stopping portion 283 are arranged at an angle. Further, the sliding portion 281 forms an acute angle with the docking direction and is deflected to the side where the fuselage 10 is located, and the sliding portion 281 is slidably engaged with the body 21. The stopping portion 283 forms an acute angle with the docking direction and is deflected to the side away from the fuselage 10. During the docking process between the feeder trolley 20 and the machine body 10, the connecting part of the sliding part 281 and the stop part 283 abuts against the baffle bar 11 to drive the sliding part 281 to move upward relative to the machine body 21. After the feeder trolley 20 is docked in place on the machine body 10, the movable plate 28 moves downward back to its original position under the action of gravity, thereby sealing the gap between the recycling channel 21a and the baffle bar 11. This prevents the waste belt entering the recycling channel 21a from the feeder 30 from running into other positions on the machine body 21 through the gap between the recycling channel 21a and the baffle bar 11, thus hindering the normal operation of the feeder trolley 20 or causing abnormal waste belt recycling. After the waste belt entering the recycling channel 21a from the feeder 30 enters the waste box equipped with the feeder trolley 20 normally, it can be easily recycled normally afterward, avoiding environmental pollution.

[0056] The body 21 may be provided with a limiting groove to limit the sliding range of the sliding part 281. For example, the body 21 may be provided with an elongated limiting groove along the sliding direction of the sliding part 281, and the sliding part 281 may have a protrusion that extends into the limiting groove and slides into the limiting groove. Before the feeder cart 20 docks with the machine body 10, the protrusion of the sliding part 281 is kept in a position relatively close to the ground under the action of gravity. The groove wall of the limiting groove restricts the extreme position of the downward movement of the movable plate 28, thereby preventing the movable plate 28 from falling out of the body 21 and preventing the movable plate 28 from extending too far and obstructing the docking of the feeder cart 20 with the machine body 10. During the docking process of the feeder cart 20 with the machine body 10, the connection part of the sliding part 281 and the stop part 283 abuts against the baffle bar 11 to drive the sliding part 281 to move upward relative to the body 21. After the feeder cart 20 docks with the machine body 10, the movable plate 28 moves downward back to its original position under the action of gravity, thereby closing the gap between the recycling channel 21a and the baffle bar 11.

[0057] Furthermore, the connection between the sliding part 281 and the stop part 283 on the side facing the ground, or the part that abuts against the stop bar 11, can be processed into an arc transition to ensure the smooth relative sliding of the movable plate 28 and the stop bar 11 and prevent the movable plate 28 from getting stuck.

[0058] Furthermore, the end of the baffle bar 11 facing away from the recycling channel 21a has a guide portion 111. The guide portion 111 extends along the docking direction and has a guide slope 1111. The guide slope 1111 is inclined relative to the docking direction. During the docking process of the feeder cart 20 to the machine body 10, the connection part of the sliding part 281 and the stop part 283 abuts against the guide slope 1111. For example, the inclination angle of the guide slope 1111 relative to the docking direction is small, for example, within 30 degrees. During the docking process of the feeder cart 20 to the machine body 10, the guide slope 1111 can slowly push the movable plate 28 upward, preventing the movable plate 28 from getting stuck. Furthermore, in some embodiments, the baffle bar 11 has the above-mentioned guide portions 111 at both ends in the second direction, that is, the two guide portions 111 are located at opposite ends of the baffle bar 11 in a one-to-one correspondence, so as to reduce the contact area between the movable plate 28 and the baffle bar 11 during the docking process, reduce the docking resistance, and prevent the movable plate 28 from getting stuck.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
