Description

Technical Field

[0001] The invention relates to the technical field of spoke manufacturing, and in particular to a spoke end conical piece adhesion device. Background Art

[0002] In the prior application, the applicant proposed a solution for forming a tapered structure at the end of a carbon fiber spoke. Generally speaking, a tapered section is designed at the end of the spoke, and the outer diameter of the tapered section gradually increases along the length direction of the spoke toward the end of the spoke. The metal piece provided at the end of the spoke can form a limit fit with the tapered section in the length direction, thereby fixing the metal piece to the spoke body, solving the problem that the metal piece at the end of the carbon fiber spoke is difficult to combine and fix with the carbon fiber spoke body. After being assembled on the rim, the limit fit between the tapered section and the metal piece in the length direction can effectively ensure that the spoke has a good performance in withstanding the tension of the rim and the hub in the length direction. Figure 1 In the process of forming the tapered section, the applicant designed a flexible tapered sheet, which is unfolded on a plane into a right triangle, with two right-angled sides and a hypotenuse, wherein the right-angled side can be attached to the spoke end and the extension direction of the right-angled side is consistent with the extension direction of the spoke body, and then the tapered sheet attached to the spoke end is wound on the spoke end. Due to the triangular shape of the tapered sheet itself, a tapered section with an outer diameter gradually increasing toward the end of the spoke end is automatically formed at the spoke end. Before forming the tapered section, the metal piece on the spoke can be inserted into the spoke body first, and after the tapered section is formed, the metal piece can be inserted into the tapered section to form a limited fit between the two.

[0003] Currently, the conical pieces are attached to the spoke ends manually, which results in low production efficiency and high labor costs. Summary of the invention

[0016] It can be seen from the above description of the present invention that, compared with the prior art, the present invention has the following beneficial effects:

[0017] Technical solution 1 provides a spoke end conical piece adhesion device, which mainly includes a frame, a adhesion component and a displacement component; wherein the adhesion component is installed on the frame and is provided with a placement portion and a clamping head, the conical piece can be laid flat on the placement portion, and the clamping head is arranged above the placement portion, and the clamping head can be moved up and down along a vertical first direction; in addition, the displacement component is provided with a receiving groove and a displacement mechanism, wherein the receiving groove can accommodate the spoke and expose the end of the spoke in a second direction, and the displacement mechanism can drive the spoke to reciprocate along the first direction, thereby driving the spoke to sit on the placement portion and adhere the conical piece; when adhering, firstly lay the conical piece flat on the placement portion, then place the spoke in the receiving groove, and The end of the spoke is exposed, and the displacement assembly is at a higher position at this time. When the spoke is placed, the spoke will not interfere with the adhesion assembly; then the displacement mechanism drives the spoke to move downward, so that the spoke can be placed on the placement part and adhere to the conical piece, but at this time the spoke is only adhered to the conical piece by gravity, and the adhesion between the two is not strong enough, so a pressing head is provided, and the pressing head can move downward and press the end of the spoke after the conical piece is adhered to the end of the spoke, so that the end of the spoke can firmly adhere to the conical piece. After the pressing head presses the end of the spoke, the pressing head moves up, and then the displacement mechanism drives the spoke to move upward, and the conical piece is taken away from the placement part together with the spoke, and then the spoke is taken out of the accommodating groove, and the adhesion process of the conical piece at the end of the spoke can be completed. Through the adhesion equipment, the conical piece adhesion process of the spoke end can be automatically realized, which reduces labor costs and improves production efficiency.

[0018] In the second technical solution, a groove is provided in the placement part. When the conical piece is laid flat on the placement part, it crosses the groove. The position of the spoke corresponds to the groove. When the spoke moves downward with the displacement assembly, the end of the spoke will first contact the conical piece. Then, the conical piece is deformed under the action of the spoke. At the same time, the spoke falls into the groove. The bent and deformed part of the conical piece will contact the outer surface of the end of the spoke. The groove structure can increase the contact area between the conical piece and the outer surface of the end of the spoke, thereby improving the adhesion of the conical piece to the end of the spoke. If the conical piece is laid flat on the placement part without the groove structure, when the end of the spoke is located on the placement part, since the shape of the end of the spoke is generally cylindrical, only a very small part contacts the conical piece. In this way, even if the end of the spoke is pressed by a clamping head, the adhesion of the two is limited. In addition, more importantly, by setting the groove, the conical piece can be placed on the placement part with greater redundancy in the placement position; it is easy to understand that if the groove is not set, when the conical piece is adhered, in order to avoid the conical piece having excess edges exposed on the spoke ends to hinder the subsequent adhesion process, it is necessary to ensure that the spoke ends are located at the straight edge of the conical piece, which requires that the placement position of the conical piece needs to be extremely accurate, and at the same time, the position of the spokes in the displacement assembly and the position of the displacement assembly relative to the adhesion assembly must always be consistent, which obviously puts higher requirements on the overall manufacturing accuracy of the equipment, and also increases the manufacturing cost of the equipment. In this technical solution, a groove is set on the placement part, and the conical piece is placed across the groove. Due to the large size of the groove, the spoke ends can enter the groove more easily. At the same time, the conical piece will deform with the movement of the spoke ends, thereby avoiding the edge of the conical piece from being exposed outside the spoke ends. Therefore, the conical piece does not need to be placed very accurately, as long as the conical piece spanning the other side of the groove is roughly determined.

[0019] In the third technical solution, the groove structure is further refined so that the groove depth is greater than the radius of the spoke end, and the groove edge extends toward the groove wall, thereby enhancing the wrapping of the spoke end by the conical piece. When the spoke end falls into the groove, the conical piece can better wrap the spoke end, forming a tighter fit, further improving the adhesion strength and reliability. This structural design also helps to prevent the conical piece from shifting during the adhesion process, ensuring the accuracy of the adhesion position.

[0020] In the fourth technical solution, a vacuum negative pressure device and a specific placement block structure are introduced, and the conical piece is adsorbed and fixed through the first negative pressure port when the vacuum negative pressure device is working. This allows the conical piece to be stably positioned in the placement part before being adhered by the spokes, avoiding movement due to its own gravity or slight vibration, and improving the accuracy of the conical piece placement and the convenience of operation. Vacuum adsorption fixation also helps to ensure that the conical piece remains flat during the adhesion process, improving the final adhesion quality.

[0021] In technical solution five, a clamping drive mechanism is added, which is used to drive the clamping block to reciprocate in the first direction, thereby realizing active control of the clamping force of the conical piece. Compared with clamping by gravity alone, the clamping drive mechanism can provide a more stable and controllable clamping force, ensuring full contact between the conical piece and the spoke end, significantly improving the firmness and consistency of adhesion. At the same time, active control of the clamping force also enables the device to adapt to conical pieces of different materials or sizes, improving the versatility of the device.

[0022] In technical solution six, a rotating disk and multiple placement blocks fixed at circumferential intervals are introduced to realize multi-station synchronous operation. The operator can place the conical sheet on the placement block that has not entered the bonding station, and multiple placement blocks can take turns entering the bonding station to bond the conical sheet, thereby separating the placement and bonding operation positions of the conical sheet, facilitating the loading of the conical sheet and improving the production efficiency of the equipment.

[0023] In the technical solution 7, the rotation angle of the rotating disk is precisely controlled by the rotating drive mechanism, ensuring that each rotation is at the preset second angle, and the second angle is equal to the first angle of the placement blocks arranged at intervals on the rotating disk. This ensures that each placement block can be accurately rotated to the working position, achieving precise connection and circulation of the process, and ensuring the stability and reliability of multi-station operation.

[0024] In technical solution eight, a negative pressure connecting component is introduced to realize independent control and distribution of vacuum negative pressure of multiple placement blocks. The first negative pressure port of each placement block is connected to the vacuum negative pressure device through independent second and third negative pressure channels, which ensures that the vacuum adsorption effect of each station is not affected by other stations, and improves the reliability and stability of vacuum adsorption. The cooperation between the negative pressure driving mechanism and the negative pressure connecting piece can accurately control the application and disconnection of negative pressure, so as to coordinate with the movement of the rotating disk. When the rotating disk rotates, the negative pressure connecting piece moves up to separate the second negative pressure port and the third negative pressure port. After the rotating disk rotates to the position and stops, the negative pressure connecting piece moves down to connect the third negative pressure port with the next second negative pressure port on the rotating disk. Through this negative pressure connecting component, in the equipment using the rotating disk, the problem of difficult layout of the negative pressure pipeline caused by the rotation of the rotating disk can be solved, which greatly simplifies the layout problem of the negative pressure pipeline.

[0025] In technical solution nine, a sliding component is provided, through which the displacement component can be driven to translate, so that the displacement component can load materials at one position, adhere the conical sheet at another position, and then move to the unloading position, thereby realizing the automation of the adhesion process, and separating the loading, adhesion and unloading positions can avoid mutual interference between components, which is beneficial to improving the automation level of the adhesion equipment.

[0026] In technical solution ten, the accommodating mechanism includes two accommodating seats, and the positioning grooves respectively arranged on the two accommodating seats cooperate to form the above-mentioned accommodating grooves. By forming the accommodating grooves through the accommodating seats, the spokes can be limited by the accommodating grooves only at the positions near the two ends, and the middle part can be conveniently taken; two adhesion components are arranged at the same time, and the two adhesion components can simultaneously perform adhesion operations on the conical pieces at the two ends of the spokes, which can further improve the adhesion efficiency.

[0050] Example

[0051] Reference Figure 2 The embodiment of the present invention relates to a spoke end conical piece 12 adhesion device, which mainly includes a frame 20, an adhesion component 30, a displacement component 40, a negative pressure connection component 50, a sliding component 60 and a vacuum negative pressure device.

[0052] First refer to Figure 1, which shows the structure of the spoke with the conical piece 12 attached. The spoke as a whole includes a spoke body 10, a connecting cap 11 and a conical piece 12, wherein there are two connecting caps 11, which are respectively sleeved on the spoke body 10 from both ends, and there are two conical pieces 12, which are respectively attached to the two ends of the spoke body 10. The conical piece 12 can be attached to the spoke body 10 by means of a glue station, and at the same time, one side surface of the conical piece 12 itself can be designed to be sticky, so that the side surface is used as the inner side during winding, so that the conical piece 12 will not fall apart after adhesion. The triangular shape of the conical piece 12 can automatically form a conical section at the end of the spoke after the conical piece 12 is adhered. The size and shape of the conical section are adapted to the size and shape of the inner through hole of the connecting cap 11. The connecting cap 11 can be pulled outward to the position of the conical section, and the connecting cap 11 and the spoke body 10 are limited in the length direction through the conical section, which can effectively increase the tensile force that the connecting cap 11 can withstand when pulling the connecting cap 11. In this embodiment, the spoke body 10 and the conical piece 12 are made of carbon fiber material, and the connecting cap 11 is made of metal. After the conical piece 12 is wrapped around the spoke body 10, the conical piece 12 and the spoke body 10 can be cured into one through a curing process to prevent the conical piece 12 from falling off the spoke body 10. After the two are cured into one, the connecting cap 11 can be pulled to the position of the conical section.

[0053] Reference Figure 2 The spoke end conical piece 12 adhering device involved in the embodiment of the present invention is used to adhere the conical piece 12 to the spoke end, wherein the adhering component 30 is installed on the frame 20 and is provided with a placement portion 311 and a pressing head 32; the placement portion 311 is suitable for laying the conical piece 12 flat; the pressing head 32 is located above the placement portion 311 and is suitable for reciprocating along a vertical first direction relative to the frame 20; the displacement component 40 is installed on the frame 20 and is provided with a receiving groove 42 and a displacement mechanism 44; the receiving groove 42 is suitable for accommodating the spoke and making the end of the spoke exposed in a second direction, which is perpendicular to the first direction; the displacement mechanism 44 drives the spoke to reciprocate along the first direction, so that the spoke is seated on the placement portion 311 and adheres to the conical piece 12; the pressing head 32 moves down and presses the spoke end after adhering the conical piece 12 to the spoke end.

[0054] It is necessary to define the terms related to orientation used in this specification and claims. Figures 1 to 10 In this specification, the words front, back, left, right, up, and down are used to describe the directions, wherein the left-right direction corresponds to the second direction referred to in this specification and the claims, the up-and-down direction corresponds to the first direction referred to in this specification and the claims, and the front-to-back direction corresponds to the third direction referred to in this specification and the claims.

[0055] First, refer to Figure 2 In this embodiment, the adhesion component 30 and the displacement component 40 are both installed on a frame 20. The frame 20 includes a main support as a supporting body, and a platform 21 arranged above the main support. The platform 21 and the main support are connected by a slide rail 22 and a slider 23. Specifically, the main support is a table-shaped component, which can be made of aluminum profiles or other materials. The platform 21 is a flat plate-shaped component. There are two platforms 21, which are respectively installed on the main support in the left and right directions. The slide rail 22 and the slider 23 cooperate to form a sliding structure. The slide rail 22 is fixedly installed on the top of the main support, and the slide rail 22 extends in the left and right directions. The slider 23 is installed on the slide rail 22. The slider 23 can slide back and forth along the extension direction of the slide rail 22. The platform 21 is fixed to the slider 23 by bolts, so the platform 21 can slide in the left and right directions relative to the main support. Through the cooperation of the slide rail 22 and the slider 23, the two platforms 21 can slide in the left-right direction, so that the distance and respective positions of the two platforms 21 in the left-right direction can be adjusted. Among them, a driving motor or a driving cylinder can be set on the frame 20 corresponding to each platform 21 to control the movement of the platform 21 in an automated manner and accurately adjust the position of the platform 21. In addition, referring to Figure 2 and Figure 3 The frame 20 also includes a flat plate-shaped drive mounting plate 24, which is fixedly mounted above the platform 21 through a plurality of support rods extending in the up-down direction, and a clearance space is formed between the lower surface of the drive mounting plate 24 and the upper surface of the platform 21, and some components of the adhesion assembly 30 are mounted on the drive mounting plate 24.

[0056] Reference Figure 3 and Figure 8 The adhesion component 30 includes a placement block 31, the top surface of the placement block 31 forms the placement portion 311, and the placement block 31 is provided with a first negative pressure channel connected to the vacuum negative pressure device, and the placement block 31 is provided with a plurality of first negative pressure ports 312 connected to the first negative pressure channel at a position corresponding to the placement portion 311, and the first negative pressure ports 312 fix the conical sheet 12 by negative pressure adsorption when the vacuum negative pressure device is working.

[0057] A vacuum negative pressure device can be arranged inside the frame 20 of the bonding device. The vacuum negative pressure device can generate negative pressure after being powered on and transmit the pressure to the required position through the negative pressure pipeline, thereby realizing negative pressure adsorption of the workpiece. The vacuum negative pressure device is a conventional device for realizing negative pressure adsorption in the art, and will not be described in detail here.

[0058] Place block 31's structure reference Figure 3, which is roughly a rectangular block-shaped component, and a placement portion 311 is formed on the upper surface of the placement portion 311, and the conical piece 12 can be placed flat on the placement portion 311, and when the conical piece 12 is placed on the placement portion 311, the sticky side of the conical piece 12 faces upward, and the non-sticky side faces downward. The placement block 31 is provided with a plurality of first negative pressure ports 312 at the position of the placement portion 311, and these first negative pressure ports 312 are arranged in a regular manner, and each first negative pressure port 312 is designed to be of a smaller size, and adjacent first negative pressure ports 312 are designed to have a smaller distance between them. Such a configuration allows the conical piece 12 to be placed on the placement portion 311, and the negative pressure formed by the first negative pressure ports 312 can act on the conical piece 12 more evenly, thereby preventing the conical piece 12 from being deformed or bent due to negative pressure adsorption. Among them, a first negative pressure channel is provided inside the placement block 31, and the first negative pressure channel can be connected to the vacuum negative pressure device through a negative pressure pipeline, so that negative pressure is formed through the vacuum negative pressure device, and the conical piece 12 is adsorbed and fixed at the position of the first negative pressure port 312. In this way, the conical piece 12 can be stably positioned in the placement portion 311 before being adhered by the spokes, avoiding movement due to its own gravity or slight vibration, and improving the placement accuracy and operation convenience of the conical piece 12. Vacuum adsorption fixation also helps to ensure that the conical piece 12 remains flat during the adhesion process, improving the final adhesion quality.

[0059] In particular, refer to Figure 7 and Fig.10 The placement portion 311 is recessed to form a groove 313 for the end of the spoke to fall into, and the conical piece 12 is laid flat on the placement portion 311 across the groove 313 .

[0060] Specifically, a groove 313 is provided on the surface of the placement portion 311 of the placement block 31, which penetrates the upper surface of the placement block 31 in the left-right direction and is recessed downward. The shape and size of the groove 313 are roughly adapted to the shape and size of the spoke end, but the size of the groove 313 is larger than the size of the spoke end to ensure that the spoke end can fall into the groove 313. Figure 8When the conical piece 12 is placed, part of it will cross the groove 313, that is, the conical piece 12 will cover the groove 313, but the width of the conical piece 12 is obviously smaller than the width of the placement portion 311, so the conical piece 12 will only cover part of the groove 313. In this way, since the position of the spoke corresponds to the groove 313, when the spoke moves downward with the displacement assembly 40, the end of the spoke will first contact the conical piece 12, and then the conical piece 12 will be deformed under the action of the spoke, and the spoke will fall into the groove 313, and the bent and deformed part of the conical piece 12 will contact the outer surface of the end of the spoke. The design of the groove 313 structure can increase the contact area between the conical piece 12 and the outer surface of the end of the spoke, thereby improving the firmness of the conical piece 12 adhering to the end of the spoke. If the conical sheet 12 is laid flat on the placement portion 311 without the groove 313 structure, when the spoke end is located on the placement portion 311, since the shape of the spoke end is generally cylindrical, only a very small part is in contact with the conical sheet 12, so even if the spoke end is pressed by the pressing head 32, the degree of adhesion between the two is limited. In addition, more importantly, by setting the groove 313, the conical sheet 12 can be placed on the placement portion 311. The position where it can be placed has greater redundancy; it is easy to understand that if the groove 313 is not set, when the conical sheet 12 is adhered, in order to avoid the conical sheet 12 having excess edges exposed on the spoke ends to hinder the subsequent adhesion process, it is necessary to ensure that the spoke ends are located at the straight edge of the conical sheet 12, which requires that the placement position of the conical sheet 12 needs to be extremely accurate, and the position of the spoke in the displacement component 40 and the position of the displacement component 40 relative to the adhesion component 30 must always be consistent, which obviously puts higher requirements on the overall manufacturing accuracy of the device, thereby increasing the manufacturing cost of the device. In the present technical solution, a groove 313 is provided on the placement portion 311, and the conical piece 12 is placed across the groove 313. Since the groove 313 is relatively large, the spoke end can enter the groove 313 relatively easily. At the same time, the conical piece 12 will deform with the movement of the spoke end, thereby preventing the edge of the conical piece 12 from being exposed outside the spoke end. Therefore, the placement position of the conical piece 12 does not need to be determined very accurately, and it is sufficient to roughly determine the portion of the conical piece 12 that spans the other side of the groove 313.

[0061] Further, refer to Fig.10The depth of the groove 313 is greater than the radius of the end of the spoke, and the edge of the notch 314 of the groove 313 extends toward the groove wall 315 thereof, so that after the spoke end adheres to the conical sheet 12 and falls into the groove 313, the conical sheet 12 surrounds the spoke end. The cross section of the groove 313 is roughly semicircular, with the notch 314 formed above it, and the inner groove wall 315 is arc-shaped to adapt to the cylindrical spoke end. The size of the notch 314 should be larger than the outer diameter of the spoke end to ensure that the spoke end can fall into the groove 313, and the depth of the groove 313 should be larger than the radius of the spoke end. That is to say, when the spoke end falls into the groove 313, the portion of the spoke end exposed from the groove 313 should belong to the upper portion of the spoke end, and the distance of the edge of the notch 314 of the groove 313 should be smaller than the maximum distance of the groove wall 315 of the groove 313. In this way, the groove 313 forms an opening structure with inward surrounding. When the spoke end falls into the groove 313 together with the conical piece 12, the notch 314 and the groove wall 315 of the groove 313 will apply force to the conical piece 12, so that the conical piece 12 is attached to the outer surface of the spoke end. At the same time, due to the shape design of the notch 314 of the groove 313 and the toughness of the material of the conical piece 12 itself, the conical piece 12 will wrap around the spoke end. The wrapping here does not mean that the conical piece 12 completely surrounds the spoke end, but that the conical piece 12 partially covers the spoke end, for example, one side edge of the conical piece 12 is wrapped toward the other side edge and attached to the spoke end. In this way, when the spoke end falls into the groove 313, the conical piece 12 can better wrap the spoke end to form a tighter fit, further improving the adhesion strength and reliability, and also helping to prevent the conical piece 12 from shifting during the adhesion process, ensuring the accuracy of the adhesion position. In addition, when the pressing head 32 presses down the spoke end, it will contact the conical piece 12 located above the spoke end, so that the conical piece 12 is more firmly adhered to the spoke end.

[0062] Reference Figure 3 and Figure 4 The adhesion component 30 also includes a clamping drive mechanism 33; the clamping drive mechanism 33 is installed on the frame 20, the clamping block is fixed to the output end of the clamping drive mechanism 33, and is suitable for being driven by the clamping drive mechanism 33 to reciprocate along the first direction.

[0063] Specifically, the clamping head 32 is a block-shaped component, which can move up and down under the drive of the clamping drive mechanism 33, and clamp the spoke end when moving down, and then move up to enable the spoke to leave the adhesion station. The clamping drive mechanism 33 is installed on the drive mounting plate 24 of the frame 20. The main body of the clamping drive mechanism 33 is a cylinder, which can move its output end up and down by changing the air pressure. The clamping output end 331 of the clamping drive mechanism 33 is located below the drive mounting plate 24, and a clamping adapter plate 333 is fixed to the clamping output end 331 by bolts, and the clamping head 32 is fixed to the clamping adapter plate 333 by bolts. In addition, two clamping sliding rods 332 are also provided in the clamping drive mechanism 33, and the two clamping sliding rods 332 are connected to the drive mounting plate 24 in a sliding manner in the up and down direction, that is, under the restriction of the drive mounting plate 24, the two clamping sliding rods 332 can only move in the up and down direction. The two clamping sliding rods 332 are fixedly connected to the clamping adapter plate 333, so that the clamping head 32 can only move in the up and down directions, ensuring the accuracy of the movement route of the clamping head 32. A clamping drive mechanism 33 is added, and the clamping block is driven to reciprocate in the first direction by the mechanism, thereby realizing active control of the clamping force of the conical piece 12. Compared with clamping relying solely on gravity, the clamping drive mechanism 33 can provide a more stable and controllable clamping force, ensuring full contact between the conical piece 12 and the spoke end, significantly improving the firmness and consistency of adhesion. At the same time, active control of the clamping force also enables the device to adapt to conical pieces 12 of different materials or sizes, thereby improving the versatility of the device.

[0064] In addition, the adhesion assembly 30 further includes a rotating disk 34, the rotating disk 34 rotates relative to the frame 20 around a first axis in a first direction, and a plurality of the placement blocks 31 are fixedly arranged at preset first angles along the circumference of the rotating disk 34. In this embodiment, the adhesion assembly 30 further includes a rotation driving mechanism 35, the rotation driving mechanism 35 is mounted on the frame 20, and an output end thereof is fixedly connected to the rotating disk 34; the rotation driving mechanism 35 is adapted to drive the rotating disk 34 to rotate around the first axis by a preset second angle each time, and the second angle is equal to the first angle.

[0065] Specifically, refer to Figure 3 and Figure 4The rotating drive mechanism 35 includes a rotating motor 351 and a rotating connection block 352. The rotating motor 351 is installed below the platform 21 of the frame 20. The rotating connection block 352 is arranged at the output end of the rotating motor 351. The rotating connection block 352 can rotate around the first axis as the output end of the rotating motor 351 rotates. At the same time, the rotating connection block 352 extends from the platform 21 from the bottom to the top and is fixedly connected to the rotating disk 34 by bolts. In this embodiment, the number of the placement blocks 31 in the adhesion component 30 is four. The four placement blocks 31 are fixedly installed on the outer edge of the rotating disk 34 along the circumferential direction, and the interval angle between the placement blocks 31, that is, the first angle, is 90 degrees. Driven by the rotating drive mechanism 35, the angle of each rotation of the rotating disk 34, that is, the second angle, is also 90 degrees. In the initial state, there is always a placement block 31 in the correct adhesion position. After the rotating drive mechanism 35 rotates once, the next placement block 31 will also be rotated to the adhesion position. The adhesion position is the position for adhering the cone piece 12 to the spoke end. The introduction of the rotating disk 34 and a plurality of placement blocks 31 fixed at intervals along the circumference realizes the synchronous operation of multiple stations. The operator can place the cone sheet 12 on the placement block 31 that has not entered the adhesion station, and the plurality of placement blocks 31 can enter the adhesion station in turn to adhere the cone sheet 12, thereby separating the placement and adhesion operation positions of the cone sheet 12, facilitating the loading of the cone sheet 12 and improving the production efficiency of the equipment. In addition, the rotation angle of the rotating disk 34 is precisely controlled by the rotating drive mechanism 35 to ensure that each rotation is a preset second angle, and the second angle is equal to the first angle of the placement blocks 31 arranged at intervals on the rotating disk 34. This ensures that each placement block 31 can be accurately rotated to the working position, realizes the precise connection and cycle of the process, and ensures the stability and reliability of the multi-station operation.

[0066] The adhesion device also includes a negative pressure communication component 50 and a sliding component 60. The negative pressure communication component 50 includes a negative pressure driving mechanism 51 and a negative pressure communication piece 52; the rotating disk 34 is provided with a plurality of second negative pressure channels corresponding to and connected with the first negative pressure channels of each placement block 31, and each second negative pressure channel is provided with a second negative pressure port 341 at one end away from the corresponding placement block 31; the negative pressure driving mechanism 51 is installed on the frame 20, and the negative pressure communication piece 52 is fixedly arranged at the output end of the negative pressure driving mechanism 51, and is suitable for being driven by the negative pressure driving mechanism 51 to reciprocate in the first direction; the negative pressure communication piece 52 is provided with a negative pressure port 341 connected to the vacuum negative pressure channel ... provided with a negative pressure port 341 connected to the vacuum negative pressure channel 31; the negative pressure driving mechanism 51 is provided with a negative pressure driving mechanism 51; the negative pressure communication piece 52 is provided with a negative pressure port 341 connected to the vacuum negative pressure channel 31; the negative pressure driving mechanism 51 is provided with a negative pressure driving mechanism 51; the negative pressure communication piece 52 is provided with a negative pressure port 341 connected to the vacuum negative pressure channel 31; the negative pressure driving mechanism 51 is provided with a negative pressure driving mechanism 51; the negative pressure communication piece 52 is provided with a negative pressure port 341 connected to the vacuum negative pressure channel 31; the negative pressure driving mechanism 51 is provided with a negative pressure driving mechanism 51; The device is connected to several third negative pressure channels, and the vacuum negative pressure device independently supplies pressure for each of the third negative pressure channels; a second negative pressure port 341 is formed at one end of each of the third negative pressure channels away from the vacuum negative pressure device; the first negative pressure port 312 and the second negative pressure port 341 are arranged in the same number at a preset third angle at a circumferential interval relative to the first axis, the third angle is equal to the first angle, and the negative pressure driving mechanism 51 is suitable for driving the negative pressure connecting piece 52 to move toward the rotating disk 34 so that the second negative pressure port 341 is connected to the first negative pressure port 312 corresponding to a position.

[0067] Specifically, refer to Figure 3 and Figure 4The negative pressure drive mechanism 51 is fixedly mounted on the drive mounting plate 24. The main body of the negative pressure drive mechanism 51 is a cylinder, and its output end forms a negative pressure drive output end 511. The negative pressure drive output end 511 is fixedly connected to the negative pressure connecting piece 52. Four third negative pressure ports 521 are arranged around the first axis of the rotating disk 34 at intervals of 90 degrees, and each of the four third negative pressure ports 521 is independently connected to the vacuum negative pressure device through a negative pressure pipeline. At the same time, four second negative pressure ports 341 are arranged at corresponding positions on the rotating disk 34. The four second negative pressure ports 341 are connected to the second negative pressure channel in the rotating disk 34, and each second negative pressure channel is connected to the first negative pressure channel of a placement block 31 through a negative pressure pipeline. In addition, two negative pressure drive sliding rods 512 extending in the up-down direction are also provided on both sides of the main body of the negative pressure drive mechanism 51, which can also limit the negative pressure drive output end 511 from driving the negative pressure connecting piece 52 to move in the up-down direction. When the rotating disk 34 is in a state of stopping rotation, the negative pressure connecting member 52 can be driven by the negative pressure driving mechanism 51 to move downward, and each third negative pressure port 521 can be docked and connected with a second negative pressure port 341 at a corresponding position. Before the rotating disk 34 rotates, the negative pressure connecting member 52 is driven by the negative pressure driving mechanism 51 to move upward, and the third negative pressure port 521 leaves the corresponding second negative pressure port 341. When the rotating disk 34 rotates 90 degrees to the next position, the negative pressure connecting member 52 can be driven by the negative pressure driving mechanism 51 to move downward and make the third negative pressure port 521 docked and connected with a second negative pressure port 341 at a corresponding position. In order to ensure the sealing effect of docking and connection, a sealing ring is provided on the negative pressure connecting member 52 corresponding to each third negative pressure port 521. When the negative pressure connecting member 52 moves downward to the third negative pressure port 521 to dock with the second negative pressure port 341, the sealing ring will be squeezed by the upper surface of the rotating disk 34, thereby sealing the gap between the third negative pressure port 521 and the second negative pressure port 341. By introducing the negative pressure communication component 50, the vacuum negative pressure of multiple placement blocks 31 is independently controlled and distributed. The first negative pressure port 312 of each placement block 31 is connected to the vacuum negative pressure device through independent second and third negative pressure channels, ensuring that the vacuum adsorption effect of each station is not affected by other stations, and improving the reliability and stability of vacuum adsorption. The cooperation of the negative pressure driving mechanism 51 and the negative pressure communication member 52 can accurately control the application and disconnection of negative pressure, so as to coordinate with the movement of the rotating disk 34. When the rotating disk 34 rotates, the negative pressure communication member 52 moves up to separate the second negative pressure port 341 and the third negative pressure port 521. After the rotating disk 34 rotates to the position and stops, the negative pressure communication member 52 moves down to connect the third negative pressure port 521 with the next second negative pressure port 341 on the rotating disk 34. Through the negative pressure communication component 50, in the equipment using the rotating disk 34, the problem of difficult arrangement of the negative pressure pipeline caused by the rotation of the rotating disk 34 can be solved, which greatly simplifies the arrangement problem of the negative pressure pipeline.

[0068] Reference Figure 5 The sliding assembly 60 includes a sliding seat 61, a sliding member 62 and a sliding drive mechanism; the output end of the sliding drive mechanism is connected to the sliding member 62 and drives the sliding member 62 to slide on the sliding seat 61 along a third direction perpendicular to both the first direction and the second direction; the sliding member 62 is fixedly connected to the displacement assembly 40 and drives the displacement assembly 40 to translate along the third direction.

[0069] Specifically, the sliding assembly 60 is mounted on the frame 20 and is located in the middle of the two platforms 21 in the left-right direction. In the sliding assembly 60, the sliding seat 61 extends in the front-to-back direction and is fixedly mounted on the frame 20. The above-mentioned sliding drive mechanism is installed inside the sliding seat 61. The sliding drive mechanism can adopt a structure such as a threaded screw, a cylinder or an electric cylinder, and its output end is connected to the sliding member 62. The sliding member 62 forms a sliding fit with the sliding seat 61, and under the action of the sliding drive mechanism, the sliding member 62 can slide back and forth along the extension direction of the sliding seat 61, that is, the front-to-back direction. Among them, the sliding member 62 is provided with an upward plane, which can be used for the installation of the displacement assembly 40. At the same time, the sliding member 62 can reciprocate in the pre-set feeding station and the bonding station under the action of the sliding drive mechanism. At the feeding station, the operator can feed the spokes to the displacement assembly 40, and at the bonding station, the spokes located in the displacement assembly 40 can be bonded by the bonding assembly 30. The sliding member 62 can also be moved to the unloading station, where the operator can remove the spokes that have been bonded from the displacement assembly 40. The loading station and the unloading station can be at the same location. The sliding assembly 60 can drive the displacement assembly 40 to translate, so that the displacement assembly 40 can load at one location, bond the conical piece 12 at another location, and then move to the unloading location, thereby realizing the automated operation of the bonding process, and separating the loading, bonding and unloading locations can avoid mutual interference between components, which is conducive to improving the automated operation level of the bonding device.

[0070] Reference Figure 6 and Fig. 9 The displacement component 40 includes two receiving seats 41 arranged along the first direction, and the two receiving seats 41 are provided with positioning grooves 411 which are corresponding in position and penetrate along the second direction, and the openings of the two positioning grooves 411 are both upward and cooperate to form the receiving groove 42; the spokes received in the receiving grooves 42 are exposed from the two receiving seats 41 at both ends in the first direction; the adhesion components 30 are arranged in two along the second direction, and are respectively used to adhere the conical piece 12 to the two ends of the spokes in the second direction.

[0071] The displacement assembly 40 includes a fixed base 45 as an installation base. The fixed base 45 is a flat plate-shaped member. The displacement mechanism 44 is fixedly mounted on the fixed base 45. At the same time, the fixed base 45 is fixedly mounted on the sliding member 62 of the sliding assembly 60 by bolts, so that the displacement assembly 40 can reciprocate in the front-back direction under the drive of the sliding assembly 60. The displacement mechanism 44 includes a displacement cylinder 441 and a displacement connection block 442. The displacement cylinder 441 is fixedly mounted on the fixed base 45 by bolts. The displacement connection block 442 is fixedly arranged at the output end of the displacement cylinder 441 and connected to the fixed seat 43 through the displacement connection block 442. The accommodating seat 41 is then fixedly mounted to the fixed seat 43. By pressurizing and depressurizing the displacement cylinder 441, the displacement connection block 442 can be driven to move up or down, thereby driving the fixed seat 43 to move up and down. Of course, in other embodiments, the displacement cylinder 441 in the displacement mechanism 44 can be replaced by other drivers, such as electric cylinders.

[0072] The fixed seat 43 is fixedly connected to the displacement connection block 442 of the displacement mechanism 44. A sliding groove 431 is provided in the front part of the fixed seat 43 along the left-right direction. The sliding groove 431 is a sunken groove, and its two ends in the left-right direction are open and the openings face upward. The sliding groove 431 is used for adjusting the position of the accommodating seat 41 in the left-right direction. The sliding groove 431 is also provided with a plurality of through holes at a certain distance in the left-right direction. These through holes are used for bolts to pass through, so as to form a detachable fixed fitting relationship with the accommodating seat 41.

[0073] There are two accommodating seats 41, and the two accommodating seats 41 are arranged on the fixing seat 43 in the left-right direction. The shape of the accommodating seat 41 is roughly an inverted "L" shape, and the long side of the accommodating seat 41 extends in the left-right direction. A matching protrusion 412 extending in the left-right direction is provided at the bottom. The size of the matching protrusion 412 is adapted to the size of the sliding groove 431 on the fixing seat 43, so that the accommodating seat 41 can be adjusted in the left-right direction under the limit of the sliding groove 431 of the fixing seat 43; at the same time, a long strip-shaped through hole extending in the left-right direction is also provided on the long side of the accommodating seat 41 corresponding to the through hole on the sliding groove 431. When fixing the accommodating seat 41, the bolt can be passed through the through hole of the fixing seat 43 and penetrated through the through hole on the fixing seat 43, and then the bolt can be tightened. When adjusting the position of the accommodating seat 41 in the left-right direction, the bolt can be loosened, and then the position of the accommodating seat 41 can be adjusted. The short side of the receiving seat 41 extends in the up-down direction and is provided with a positioning groove 411 that runs through in the left-right direction and opens upward. The two positioning grooves 411 of the two receiving seats 41 correspond to each other and cooperate to form a receiving groove 42 of the receiving mechanism. When the spoke is placed in the receiving groove 42, the two ends of the spoke in the length direction will be placed in the two positioning grooves 411 of the two receiving seats 41 respectively, and the middle part will be suspended. Fig. 9, the positioning groove 411 can be designed to have a structure with a variable groove width. Specifically, the positioning groove 411 can be divided into two sections with different groove widths along the left and right directions, wherein the groove width of the portion close to the inner side is greater than the groove width of the portion close to the outer side, and the groove width of the inner side is adapted to the outer diameter of the connecting cap 11, and the groove width of the outer side is adapted to the outer diameter of the end of the spoke body 10. By designing the groove width of the positioning groove 411 differently, when the spoke is placed on the receiving groove 42, the positions of its two ends will be pre-determined by the position of the connecting cap 11 to a rough range, thereby making it easier to position the spoke in the receiving groove 42 at an accurate position.

[0074] The accommodating mechanism includes two accommodating seats 41. The positioning grooves 411 respectively arranged on the two accommodating seats 41 cooperate to form the above-mentioned accommodating grooves 42. The accommodating grooves 42 are formed by the accommodating seats 41, so that the spokes can be limited by the accommodating grooves 42 only near the two ends, and the middle part can be conveniently taken; at the same time, two adhesion components 30 are arranged, and the two adhesion components 30 can simultaneously adhere to the conical pieces 12 at the two ends of the spokes, which can further improve the adhesion efficiency.

[0075] The spoke end conical piece 12 adhesion device involved in the embodiment of the present invention mainly includes a frame 20, a adhesion component 30 and a displacement component 40; wherein, the adhesion component 30 is installed on the frame 20 and is provided with a placement portion 311 and a clamping head 32, the conical piece 12 can be laid flat on the placement portion 311, and the clamping head 32 is arranged above the placement portion 311, and the clamping head 32 can be moved up and down along a vertical first direction; in addition, the displacement component 40 is provided with a receiving groove 42 and a displacement mechanism 44, wherein the receiving groove 42 can accommodate the spoke and expose the end of the spoke in the second direction, and the displacement mechanism 44 can drive the spoke to reciprocate along the first direction, thereby driving the spoke to sit on the placement portion 311 and adhere the conical piece 12; when adhering, firstly, the conical piece 12 is laid flat on the placement portion 311, and then the clamping head 32 is placed in the receiving groove 42. The spokes are placed and the ends of the spokes are exposed. At this time, the displacement assembly 40 is located at a higher position. When the spokes are placed, the spokes will not interfere with the adhesion assembly 30; then the displacement mechanism 44 drives the spokes to move downward so that the spokes can be seated on the placement portion 311 and adhere to the conical piece 12. However, at this time, the spokes are only adhered to the conical piece 12 by gravity, and the degree of adhesion between the two is not strong enough. Therefore, a clamping head 32 is provided. The clamping head 32 can move downward and clamp the spoke end after the spoke end adheres to the conical piece 12, so that the spoke end can firmly adhere to the conical piece 12. After the clamping head 32 clamps the spoke end, the clamping head 32 moves upward, and then the displacement mechanism 44 drives the spokes to move upward, and the conical piece 12 is taken away from the placement portion 311 together with the spokes. Then the spokes are taken out of the accommodating groove 42, and the adhesion process of the conical piece 12 at the spoke end can be completed. By means of the bonding device, the bonding process of the conical piece 12 at the spoke end can be automatically realized, thereby reducing labor costs and improving production efficiency.
