Description

Technical Field

[0001] The present application relates to the technical field of electrostatic dust removal, and in particular to an FPC electrostatic dust removal device. Background Art

[0002] Flexible printed circuits (FPC) are an important part of modern electronic manufacturing. Their production quality directly affects the performance and reliability of electronic products. In the FPC manufacturing process, the cleanliness of the FPC protective film surface is one of the key factors to ensure product quality.

[0003] At present, the industry mainly adopts physical contact and non-contact solutions to the problem of dust removal on the FPC surface. Physical contact dust removal mainly uses sticky rollers to directly contact the FPC surface through sticky materials to absorb dust. This method has a limited contact area, a general dust removal effect, and may also cause residual glue to adhere to the FPC surface; non-contact dust removal is mainly based on electrostatic dust removal, which uses an electrostatic roller that can generate high-voltage static electricity on the surface to remove surface impurities through air adsorption, and then the sticky roller contacts the electrostatic roller to clean the impurities on the surface of the electrostatic roller.

[0004] However, the combination of electrostatic dust removal and sticky roller in the prior art requires regular tearing off of the outermost layer of adhesive paper on the sticky roller to ensure the cleaning effect. Although the electrostatic roller and the sticky roller are both configured as drawer-type pull-out structures for easy operation, the operation time for pulling out the sticky roller and tearing off a layer of adhesive paper each time is still relatively long. This not only results in frequent shutdown operations during equipment operation, but also a long shutdown time each time, making it difficult to meet the actual needs of efficient and continuous production. Summary of the invention

[0005] In order to improve the dust removal efficiency of FPC, the present application provides an FPC electrostatic dust removal device.

[0006] The present application provides an FPC electrostatic dust removal device, which adopts the following technical solution: An FPC electrostatic dust removal device comprises a mounting frame, a pull-out box, an electrostatic roller, a sticky roller, a mounting unit and a control component, wherein the electrostatic roller is rotatably arranged on the mounting frame; the pull-out box is pulled out and arranged on the mounting frame, two mounting units are arranged in the pull-out box at intervals along the vertical direction, and the two mounting units are symmetrically arranged up and down; a sticky roller is rotatably arranged in each mounting unit; the sticky roller close to the electrostatic roller abuts against the side wall of the electrostatic roller; the control component can control the two mounting units to move simultaneously and exchange positions with each other; Each of the mounting units includes two mounting side plates parallel to each other, a connecting rod connected between the two mounting side plates, and a control shaft arranged on the mounting side plates. The two ends of the adhesive roller are rotatably arranged on the two mounting side plates. The control shaft is respectively arranged on the sides of the two mounting side plates facing away from each other. A control groove for the control shaft to be inserted and slide is arranged on the side wall of the pull-out box. The control shafts on the same side of the two mounting units are respectively inserted into the upper and lower ends of the control groove. The control component can control the two control shafts to slide upward and downward along the control groove.

[0007] By adopting the above technical solution, the control component can drive the two mounting units to swap positions up and down without interrupting the operation of the equipment, so that the spare adhesive roller automatically replaces the used adhesive roller, thereby avoiding the downtime caused by the traditional manual adhesive tape tearing operation. This design not only improves production efficiency, but also ensures the continuity and stability of the electrostatic dust removal process, significantly improving the quality and reliability of FPC surface cleaning.

[0008] Optionally, the control component includes a central axis, a driving member and a driving rod. The central axis is rotatably arranged on the side panel of the pull-out box and is located at the center position of the upper and lower mounting units. The driving member can drive the central axis to rotate. The central axis is connected to the center of the driving rod and can drive the driving rod to rotate. The control shafts on the same side of the two mounting units are respectively fixedly connected to the upper and lower ends of the driving rod; the control groove includes a left arc groove and a right arc groove. When the driving rod rotates, the control shafts on the two mounting units can slide up and down along the left arc groove and the right arc groove respectively to exchange positions.

[0009] By adopting the above technical solution, the automatic exchange function of the sticky roller in the FPC electrostatic dust removal device is realized; specifically, the setting of the central axis, the driving member and the driving rod can accurately control the movement of the two mounting units, so that they slide along the left arc groove and the right arc groove respectively, driving the sticky rollers symmetrically arranged up and down to quickly complete the position exchange.

[0010] Optionally, the driving component includes a motor, a synchronous wheel and a synchronous belt, the motor is arranged on the pull-out box, the synchronous wheel is arranged on the motor output shaft and the central shaft respectively, and the synchronous belt is wound around the two synchronous wheels.

[0011] By adopting the above technical solution and utilizing the cooperation of the motor, synchronous wheel and synchronous belt, the central shaft can be stably driven, thereby simplifying the power transmission structure and improving the reliability of the device operation.

[0012] Optionally, a mounting seat is slidably arranged up and down on a side wall of the mounting side plate facing the sticky roller. Both ends of the sticky roller are mounted on the mounting seat. The mounting side plate is respectively provided with limiting grooves for the mounting seat to slide up and down on both sides of the mounting seat. The mounting side plate is further provided with a pressing member for driving the mounting seat to always slide in a direction away from the other mounting unit. The pressing member can drive the sticky roller close to the static roller to always abut against the side wall of the static roller.

[0013] By adopting the above technical solution, the up-and-down sliding design of the mounting seat in cooperation with the arrangement of the limiting groove and the pressing member can ensure that the sticky roller is always in close contact with the side wall of the static roller during the working process. This structure effectively avoids the problem of the increase in the gap between the sticky roller and the static roller caused by continuously tearing off the adhesive tape, thereby ensuring that the impurities on the surface of the static roller can be fully adsorbed and cleaned by the sticky roller, and improving the stability and reliability of the dust removal effect.

[0014] Optionally, the pressing member includes a positioning rod and a first spring arranged on the mounting side plate. The positioning rod slidably passes through the mounting seat and the first spring. The first spring is arranged on a side of the mounting seat away from the other mounting unit. When the mounting seat slides towards the side where the first spring is located until it abuts against the side wall of the limiting groove, the first spring is in a stretched state.

[0015] By adopting the above technical solution, the mounting seat is always subjected to a force in a direction away from the other mounting unit under the action of the first spring, so as to ensure that the sticky roller close to the static roller can be closely attached to the side wall of the static roller, improving the cleaning effect.

[0016] Optionally, a first plug connector and a second plug connector are respectively arranged at both ends of the sticky roller. The first plug connector includes a first plug post, a first baffle and a first plug which are connected in sequence. The first plug can be detachably inserted into the sticky roller. A first slot for inserting the first plug post is provided on the side wall of one of the mounting seats. The diameter of the first baffle is larger than the inner diameter of the sticky roller; The second plug connector includes a second plug post, a second baffle and a second plug which are connected in sequence. The second plug can be detachably inserted into the sticky roller. A second slot for inserting the second plug post is provided on the side wall of the other mounting seat. The diameter of the second baffle is larger than the inner diameter of the sticky roller. The second plug post is slidably inserted between the second baffle and the second plug. The second plug connector further includes a stop block and a second spring. The stop block is coaxially arranged on the second plug post. The second spring is arranged between the stop block and the second baffle. When the sticky roller is mounted on the mounting unit, the stop block abuts against the side wall of the mounting seat, and the second spring is in a compressed state. By adopting the above technical solution, the first plug connector and the second plug connector arranged at both ends of the sticky roller can achieve quick disassembly and assembly. The first plug and the second plug are respectively inserted into the sticky roller. Among them, the second plug connector further includes a stop block and a second spring. When the sticky roller is installed on the installation unit, the stop block abuts against the side wall of the mounting seat, and the second spring is in a compressed state, thereby providing an additional tightening force to ensure the stable fixation of the sticky roller. At the same time, by controlling the second plug post to slide and insert towards the second baffle, the sticky roller can be quickly removed, improving the replacement efficiency.

[0017] Optionally, two static rollers are provided, and the sticky roller is arranged between the two static rollers and abuts against the side walls of the two static rollers; the control groove further includes an upper radial groove and a lower radial groove connected to the upper and lower ends of the left arc groove and the right arc groove; in the working state, the two control shafts on the upper and lower installation units are respectively located in the upper radial groove and the lower radial groove; when the positions of the two control shafts are exchanged, the control component can control the control shaft located in the upper radial groove to first slide out along the upper radial groove and enter the right arc groove, and then slide into the lower groove along the right arc groove; the control component can also simultaneously control the control shaft located in the lower radial groove to first slide out along the lower radial groove and enter the left arc groove, and then slide into the upper groove along the left arc groove.

[0018] By adopting the above technical solution, the driving rod is composed of the first rod and the second rod inserted into each other, forming a matching structure of the first chute and the second chute, so that the control shaft can achieve precise positioning and stable transmission during the sliding process. The meshing relationship between the gear and the first tooth and the second tooth ensures the reliability of power transmission. At the same time, the limiting member effectively prevents the control shaft from sliding in the reverse direction when the positions are exchanged, thereby improving the stability of the device operation. This solution significantly improves the accuracy and efficiency of the position exchange of the installation unit, reduces the equipment downtime for adjustment, and meets the actual requirements of high-efficiency continuous production.

[0019] Optionally, the driving rod includes a first rod and a second rod inserted into each other. One end of the first rod facing the second rod includes a first inner rod and a first outer rod parallel to each other, and a first chute is formed between the first inner rod and the first outer rod; one end of the second rod facing the first rod includes a second inner rod and a second outer rod parallel to each other, and a second chute is formed between the second inner rod and the second outer rod; The first inner rod is inserted into the second sliding groove, and the outer side wall of the first inner rod is abutted against the inner side wall of the second outer rod; the second inner rod is inserted into the first sliding groove, and the outer side wall of the second inner rod is abutted against the inner side wall of the first outer rod; the inner side wall of the first inner rod is provided with a first tooth, and the inner side wall of the second inner rod is provided with a second tooth, and the control assembly also includes a gear and a limit member, the gear is coaxially fixed on the central axis, and the gear is respectively meshed with the first tooth and the second tooth. When the gear rotates to drive the two control shafts to slide out of the upper radial groove and the lower radial groove, the end faces of the first inner rod and the second inner rod are respectively abutted against the bottom walls of the first sliding groove and the second sliding groove; when the control shaft slides out of the upper radial groove and rotates clockwise through the right arc groove to reach the notch of the lower radial groove, the limit member can limit the control shaft from sliding back into the right arc groove.

[0020] By adopting the above technical solution, the meshing relationship between the gear and the first teeth and the second teeth ensures the reliability of power transmission. At the same time, the limiter effectively prevents the control shaft from sliding in the opposite direction when exchanging positions, thereby improving the stability of the device operation.

[0021] Optionally, the limit member includes a limit block and a third spring. A receiving groove for the limit block to slide up and down is opened on the side wall of the pull-out box. The third spring is arranged between the bottom wall of the receiving groove and the end face of the limit block. The receiving groove is connected with the left arc groove. The third spring can always drive the end of the limit block to slide into the left arc groove. The lower end of the limit block has a guide bevel on the side away from the upper end radial groove. When the control shaft slides clockwise and abuts the guide bevel, it can drive the limit block to slide into the receiving groove.

[0022] By adopting the above technical solution, a limit block, a guide bevel and a third spring are set, so that when the control shaft rotates clockwise, it can pass through the limit block smoothly. When the control shaft rotates in the opposite direction, it will be restricted by the limit block, and thus slide into the upper radial groove or the lower radial groove under the action of the gear.

[0023] In summary, the present application includes at least one of the following beneficial effects: 1. The position of the sticky rollers of the two installation units can be quickly exchanged by controlling the components, and the adhesive tape on the replaced sticky rollers can be manually torn off, which can avoid the problem of frequent shutdown for cleaning, effectively shorten the downtime, and improve the equipment operation efficiency and continuous production capacity; 2. By adding an electrostatic roller, the cleaning effect of the FPC can be further improved. At the same time, the adaptive adjustment of the control component can smoothly clean the sticky roller.

Detailed implementation manners

[0026] The following further elaborates on this application in conjunction with the attached Figure 1-8 drawings for a more detailed description.

[0027] Embodiment 1: The embodiment of this application discloses an FPC electrostatic dust removal device. Refer to Figure 1 and Figure 2The dust removal device includes a mounting frame 1, a pull-out box 2, an electrostatic roller 3, a sticky roller 4, a mounting unit 5 and a control component 6, wherein the mounting frame 1 plays the role of installing and supporting the entire dust removal device, and the conveyor belt 101 on the roller conveyor for transporting FPC passes through the mounting frame 1; the electrostatic roller 3 is rotatably mounted on the mounting frame 1, and the electrostatic roller 3 can generate high-voltage static electricity on the surface to remove impurities on the surface of the FPC by air absorption; the electrostatic roller 3 is preferably symmetrically arranged at the upper and lower ends of the conveyor belt 101 to remove dust from the upper and lower surfaces of the FPC respectively. The electrostatic roller 3 can be directly rotatably mounted on the mounting frame 1, or it can be installed by pulling to facilitate the maintenance of the electrostatic roller 3.

[0028] Reference Figure 1 and Figure 2 The pull-out box 2 is pulled out and set on the mounting frame 1, and the adhesive roller 4 is installed in the pull-out box 2. The adhesive roller 4 is used to adhere and remove impurities on the surface of the electrostatic roller 3 to clean the electrostatic roller 3. Therefore, the pull-out box 2 is also set at the upper and lower ends of the conveyor belt 101, and both are located on the side of the electrostatic roller 3 away from the conveyor belt 101. The pull-out box 2 can be installed and slid by setting a slide rail. When the pull-out box 2 is pulled out, the adhesive roller 4 can be easily replaced.

[0029] Reference Figure 2 and Figure 3 , two installation units 5 are arranged at intervals in a single pull-out box 2 along the vertical direction, and the two installation units 5 are arranged symmetrically up and down; a sticky roller 4 is rotatably arranged in each installation unit 5, that is, two sticky rollers 4 are also symmetrically arranged up and down in the pull-out box 2 through the installation units 5. Among them, the sticky roller 4 close to the electrostatic roller 3 is in contact with the side wall of the electrostatic roller 3; the control component 6 can control the two installation units 5 to move simultaneously and exchange positions with each other. In this way, when there are many impurities on the surface of the sticky roller 4 in contact with the electrostatic roller 3, the control component 6 is started to drive the two sticky rollers 4 to exchange positions. After the exchange, the sticky roller 4 with a clean surface can continue to clean the electrostatic roller 3, and the sticky roller 4 with impurities after use rotates to a position away from the electrostatic roller 3. At this time, the surface of the sticky roller 4 can be cleaned, that is, the outermost adhesive tape of the sticky roller 4 is torn off to expose the new adhesive tape layer inside, without affecting the operation of the cleaning device; thereby, the sticky roller 4 can be continuously cleaned without stopping, so that the dust removal device can continue to work, which greatly improves the work efficiency. It should be noted that, in order to facilitate the cleaning of the adhesive roller 4 far away from the electrostatic roller 3, that is, the replaced adhesive roller 4, the upper and lower ends of the mounting frame 1 are both opened to facilitate hand operation.

[0030] Reference Figure 2 and Figure 3In the embodiment of the present application, the mounting units 5 each include two mounting side plates 51 parallel to each other, a connecting rod 52 connected between the two mounting side plates 51, and a control shaft 53 arranged on the mounting side plates 51, wherein the mounting side plates 51 are rectangular plates, and the two ends of the adhesive roller 4 are rotatably arranged on the two mounting side plates 51; a plurality of connecting rods 52 can be arranged between the two mounting side plates 51 to improve the connection strength between the two mounting side plates 51; the control shaft 53 is respectively arranged on the side of the two mounting side plates 51 that are away from each other, and a control groove 21 for the end of the control shaft 53 to be inserted and slid is arranged on the inner side wall of the side plate of the pull-out box 2, and the control groove 21 is a circular groove as a whole, and the control component 6 can drive the control shaft 53 to slide in the control groove 21; the control shafts 53 on the same side of the two mounting units 5 are respectively inserted into the upper and lower ends of the control groove 21, and the control component 6 can control the two control shafts 53 to rotate clockwise or counterclockwise along the control groove 21 at the same time, so that the two control shafts 53 slide upward or downward alternately to exchange positions.

[0031] Preferably, in order to improve the stability of the control shaft 53 inserted into the control groove 21, the diameter of the end of the control shaft 53 can be increased to form a T-shaped structure. At the same time, the cross section of the control groove 21 is correspondingly opened into a T shape. When the control shaft 53 slides in the control groove 21, this matching method can limit the control shaft 53 from escaping from the control groove 21. For reference only, when this design method is adopted, the mounting side plate 51 can be assembled in a half-splicing manner to facilitate the installation of the control shaft 53 in the control groove 21.

[0032] Reference Figure 2 and Figure 3 In the embodiment of the present application, the control assembly 6 includes a central shaft 61, a driving member 62 and a driving rod 63. The central shaft 61 is vertically rotated and arranged on the side plate of the pull-out box 2, and is located at the center of the upper and lower mounting units 5, that is, at the center of the control slot 21; the driving member 62 can drive the central shaft 61 to rotate, the driving rod 63 is a rectangular long rod, the central shaft 61 is connected to the center of the driving rod 63 and can drive the driving rod 63 to rotate, and the control shafts 53 on the same side of the two mounting units 5 are respectively fixedly connected to the upper and lower ends of the driving rod 63; the control slot 21 includes a left arc groove 211 and a right arc groove 212. When the driving rod 63 rotates, the control shafts 53 on the two mounting units 5 can slide up and down and exchange positions along the left arc groove 211 and the right arc groove 212 respectively. Optionally, during installation, the driving rod 63 can be arranged on the inner side of the side plate of the pull-out box 2, and the control shaft 53 is inserted into the control slot 21 after passing through the driving rod 63.

[0033] Further, the driving member 62 includes a motor 621, a synchronous pulley 622 and a synchronous belt 623. The motor 621 is arranged on the drawer box 2, and the length direction of the output shaft of the motor 621 is parallel to the length direction of the central shaft 61. For the convenience of maintenance, the motor 621 can be arranged on the outer side wall of the side plate of the drawer box 2 by means of a support. The synchronous pulley 622 is respectively arranged on the output shaft of the motor 621 and the central shaft 61. Among them, the outer end of the central shaft 61 passes through the side plate of the drawer box 2 and is coaxially connected with the synchronous pulley 622. The synchronous belt 623 is wound around the two synchronous pulleys 622. Thus, when the motor 621 is started, the synchronous pulley 622 and the central shaft 61 can be driven to rotate by the synchronous belt 623, so as to drive the driving rod 63 to rotate, and finally drive the control shafts 53 and the adhesive wheels at both ends of the driving rod 63 to rotate.

[0034] Referring to Figure 4 and Figure 5 , in the embodiment of the present application, a mounting seat 511 is slidably arranged up and down on the side wall of the mounting plate facing the adhesive roller 4. The adhesive roller 4 is mounted on the mounting seat 511. At the same time, a pressing member 54 for driving the mounting seat 511 to slide away from the other mounting unit 5 is also provided. Generally, multiple layers of adhesive paper are covered on the surface of the adhesive roller 4. After the adhesive paper is continuously torn off during use, a distance will be generated between the adhesive roller 4 and the static roller 3, affecting the cleaning effect on the static roller 3. By setting the pressing member 54 to drive the mounting seat 511 to slide away from the other mounting unit 5, that is, the adhesive roller 4 in contact with the static roller 3 can be driven to always slide towards the static roller 3 and press against the static roller 3, so as to ensure the cleaning effect on the static roller 3.

[0035] Referring to Figure 5, specifically, a long slot for the up-and-down sliding of the mounting base 511 is formed in the middle of the mounting side plate 51, and limiting slots 512 are formed on both sides of the long slot. The overall cross-section of the mounting base 511 can be set in a "convex" shape, and the protruding parts on both sides of its lower part are inserted into the limiting slots 512 and can slide up and down along the limiting slots 512. The distance that the mounting base 511 can slide in the limiting slots 512 is preferably equal to the thickness of the adhesive tape pasted on the outer side of the sticky roller 4. The pressing member 54 includes a positioning rod 541 and a first spring 542 arranged on the mounting side plate 51. The positioning rod 541 is arranged along the vertical direction, and its two ends are fixed to the mounting side plate 51. At the same time, the positioning rod 541 slidably passes through the mounting base 511 and the first spring 542. The first spring 542 is arranged on the side of the mounting base 511 away from the other mounting unit 5. When the mounting base 511 slides towards the side where the first spring 542 is located until it abuts against the side wall of the limiting slot 512, the first spring 542 is in a stretched state, that is, the first spring 542 is always in a stretched state. This design makes the mounting base 511 always have a tendency to slide away from the other mounting unit 5. Even after the adhesive tape on the outer layer of the sticky roller 4 is continuously torn off, when it rotates to abut against the static electricity roller 3, it can always abut against the side wall of the static electricity roller 3, ensuring that there is always close contact between the sticky roller 4 and the static electricity roller 3, thereby improving the cleaning effect.

[0036] Refer to Figure 4 and Figure 5, Further optionally, for the convenience of replacing the sticky roller 4, the sticky roller 4 can be installed on the mounting seat 511 in a quick-release manner. Specifically, the two ends of the sticky roller 4 are respectively provided with a first plug connector 41 and a second plug connector 42; the first plug connector 41 includes a first plug post 411, a first baffle 412 and a first plug head 413 connected in sequence. The first plug head 413 can be detachably inserted into the sticky roller 4, preferably by an interference plugging method. A first slot for the first plug post 411 to be plugged into is opened on the side wall of one of the mounting seats 511, and the diameter of the first baffle 412 is larger than the inner diameter of the sticky roller 4. The second plug connector 42 includes a second plug post 421, a second baffle 422 and a second plug head 423 connected in sequence. The second plug head 423 can be interference inserted into the sticky roller 4. A second slot for the second plug post 421 to be plugged into is opened on the side wall of the other mounting seat 511. The diameter of the second baffle 422 is larger than the inner diameter of the sticky roller 4. The second plug post 421 is slidably plugged on the second baffle 422 and the second plug head 423. The second plug connector 42 further includes a stop block 424 and a second spring 425. The stop block 424 is coaxially arranged on the second plug post 421, and the second spring 425 is arranged between the stop block 424 and the second baffle 422. When the sticky roller 4 is installed on the mounting unit 5, the first plug post 411 is plugged into the first slot, the second plug post 421 is plugged into the second slot, the stop block 424 abuts against the side wall of the mounting seat 511, and the second spring 425 is in a compressed state. The second spring 425 can ensure that both ends of the sticky roller 4 are connected to the mounting seat 511 and are not easily detached. At the same time, when the sticky roller 4 needs to be replaced, only need to control the second plug post 421 to slide towards the direction of the second baffle 422, so that the other end of the second plug post 421 disengages from the mounting seat 511, and then the sticky roller 4 can be removed for replacement.

[0037] The implementation principle of an FPC electrostatic dust removal device according to an embodiment of the present application is as follows: By providing two symmetrically arranged mounting units 5 up and down, and realizing the automatic exchange of the two mounting units 5 through the control component 6, so that the two sticky rollers 4 can work alternately. Taking the dust removal component below the conveyor belt 101 as an example, when a sticky roller 4 has been used for a period of time, it is exchanged to the lower position through the control component 6, and the unused sticky roller 4 below is exchanged to the upper position to continue working, and then the adhesive tape on the outer circle of the sticky roller 4 replaced and moved to the lower position is torn off; In this way, the replacement of the sticky roller 4 can be completed without stopping the machine, greatly shortening the downtime and improving the operation efficiency of the equipment.

[0038] Embodiment 2: The difference between the embodiment of the present application and Embodiment 1 is that two static rollers 3 are respectively arranged at the upper and lower ends of the conveyor belt 101, and the sticky rollers 4 on the same side are arranged between the two static rollers 3 and are simultaneously in contact with the side walls of the two static rollers 3; by adding the static rollers 3, the cleaning effect on the dust and impurities on the surface of the FPC can be further improved. At the same time, the control component 6 is adaptively adjusted so that the sticky roller 4 can first move away from the static roller 3 by a certain distance in the vertical direction to smoothly rotate and alternate positions.

[0039] Refer to Figure 6 And Figure 7 In the embodiment of the present application, the control groove 21 further includes an upper radial groove 213 and a lower radial groove 214 connected to the upper and lower ends of the left arc groove 211 and the right arc groove 212; in the working state, the two control shafts 53 on the upper and lower two mounting units 5 are respectively located in the upper radial groove 213 and the lower radial groove 214; when exchanging the positions of the two control shafts 53, the control component 6 can control the control shaft 53 located in the upper radial groove 213 to first slide out along the upper radial groove 213 and enter the right arc groove 212, and then slide into the lower groove along the right arc groove 212; the control component 6 can also simultaneously control the control shaft 53 located in the lower radial groove 214 to first slide out along the lower radial groove 214 and enter the left arc groove 211, and then slide into the upper groove along the left arc groove 211. According to the actual production requirements, the two control shafts 53 can also exchange positions in a counterclockwise rotation manner. In the embodiment of the present application, for the convenience of understanding the technical solution, the following descriptions are all made in the manner of the control shaft 53 rotating clockwise to exchange positions.

[0040] In order to realize the control of the route of the control shaft 53, on the basis of the above embodiment, the driving rod 63 is further arranged to be composed of a first rod 631 and a second rod 632 that are inserted into each other. One end of the first rod 631 facing the second rod 632 includes a first inner rod 6311 and a first outer rod 6312 that are parallel to each other, and a first chute is formed between the first inner rod 6311 and the first outer rod 6312; one end of the second rod 632 facing the first rod 631 includes a second inner rod 6321 and a second outer rod 6322 that are parallel to each other, and a second chute is formed between the second inner rod 6321 and the second outer rod 6322; the first inner rod 6311 is inserted into the second chute, and the outer side wall of the first inner rod 6311 is in contact with the inner side wall of the second outer rod 6322; the second inner rod 6321 is inserted into the first chute, and the outer side wall of the second inner rod 6321 is in contact with the inner side wall of the first outer rod 6312; the inner side wall of the first inner rod 6311 is provided with first teeth, and the inner side wall of the second inner rod 6321 is provided with second teeth.

[0041] The control assembly 6 also includes a gear 64 and a limiter 65. The gear 64 is coaxially fixed on the central shaft 61, and the gear 64 meshes with the first tooth and the second tooth respectively. When the central shaft 61 rotates clockwise, the gear 64 can drive the first rod 631 and the second rod 632 to slide closer together, thereby driving the two control shafts 53 located on the same pull-out box 2 to slide out of the upper radial groove 213 and the lower radial groove 214 respectively. When the control shaft 53 escapes from the upper radial groove 213 and the lower radial groove 214, the end faces of the first inner rod 6311 and the second inner rod 6321 abut against the bottom walls of the first slide groove and the second slide groove respectively; continue to rotate the central shaft 61 clockwise, and when the gear 64 and the first inner rod 631 are in contact with each other, the first inner rod 6311 and the second inner rod 6321 are in contact with the bottom walls of the first slide groove and the second slide groove respectively. Under the cooperation and limit of the teeth and the second teeth, the first rod 631 and the second rod 632 can be driven to rotate, thereby driving the two control shafts 53 to slide along the right arc groove 212 and the left arc groove 211 respectively; when the control shaft 53 slides out of the upper radial groove 213 and rotates clockwise through the right arc groove 212 to reach the notch of the lower radial groove 214, the central shaft 61 is rotated counterclockwise. At this time, the limit member 65 can limit the control shaft 53 from sliding back into the right arc groove 212. The first rod 631 and the second rod 632 move away from each other under the cooperation of the gear 64 and the first teeth and the second teeth, thereby driving the two control shafts 53 to enter the lower radial groove 214 and the upper radial groove 213 respectively.

[0042] Reference Figure 7 and Figure 8 The limiting member 65 includes a limiting block 651 and a third spring 652. The limiting block 651 can be arranged on the left side of the upper radial groove 213 or on the right side of the lower radial groove 214, both of which can limit the reversal of the control shaft 53. The following takes the setting of the limiting block 651 on the left side of the upper radial groove 213 as an example. Specifically, a receiving groove 22 for the limiting block 651 to slide up and down is provided on the side wall of the pull-out box 2 at the bottom. The lower end of the receiving groove 22 is connected to the left arc groove 211, and the lower end of the limiting block 651 can slide into the left arc groove 211.

[0043] The third spring 652 is arranged between the bottom wall of the receiving groove 22 and the end face of the limit block 651. The receiving groove 22 is connected to the left arc groove 211. The third spring 652 can always drive the end of the limit block 651 to slide into the left arc groove 211. The lower end of the limit block 651 has a guide bevel on the side away from the upper radial groove 213. When the control shaft 53 slides clockwise and abuts the guide bevel, it can drive the limit block 651 to slide into the receiving groove 22, so as to pass through the limit block 651 smoothly. When the control shaft 53 slides counterclockwise, it will be limited by the other side wall of the limit block 651. This design realizes the automatic limit function of the control shaft 53 through the cooperation of the third spring 652 and the guide bevel, and further improves the operation accuracy and reliability of the equipment.

[0044] Optionally, in order to improve the accuracy of limiting the control shaft 53, the lower end of the limit block 651 can extend to the right, so that the right side wall of the lower end of the limit block 651 and the left side wall of the upper radial groove 213 are on the same plane. At the same time, in order to prevent the limit block 651 from slipping out of the limit groove 512, a rectangular block can also be provided on the side wall of the limit block 651, and a rectangular groove is provided on the side wall of the drawer box 2 for the rectangular block to slide, so as to limit the sliding stroke of the limit block 651.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
