Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of product assembly, and in particular to a clamping device and assembly equipment. Background Technology

[0002] In the large-scale precision manufacturing of ring-shaped electronic products, the steel ring, as a core supporting structural component, directly determines the magnetic circuit stability and sealing performance of subsequent electronic components through its coaxiality and fit clearance with the main product.

[0003] In the existing technology, the steel ring assembly operation for ring-shaped electronic products is mostly carried out by manual positioning and assembly. The operator uses simple tooling to place the pre-fixed ring product on the work station, and then embeds the steel ring into the pre-set installation groove of the product one by one by visual alignment and manual pressure. The whole process is highly dependent on the operator's skill and operating status.

[0004] In this assembly mode that relies entirely on manual labor, visual errors in manual alignment and hand tremors can easily lead to problems such as positional shifts and tilting of the steel rings. The assembly accuracy fluctuates greatly. At the same time, the lack of a unified pressure control standard during manual assembly can also easily cause hidden damage such as scratches and deformation on the surface of the steel rings or annular products. As a result, the pass rate of the final products has remained at a low level for a long time, and the overall production efficiency is also low. Summary of the Invention

[0005] The purpose of this invention is to provide a clamping device and assembly equipment to solve the problems in the prior art where assembly is highly dependent on manual labor, resulting in poor accuracy, easy damage, and low overall efficiency.

[0006] To achieve this objective, the embodiments of the present invention adopt the following technical solutions: In a first aspect, the present invention provides a clamping device for gripping a workpiece and assembling it to the outside of a product after opening a notch in the workpiece, comprising: Base; A clamping component is disposed on the base for clamping against the positioning area of ​​the workpiece; A clamping module is disposed on the base and has multiple adsorption ends, which are distributed on both sides of the abutment component to adsorb the part of the workpiece near the notch. The clamping module can drive the multiple adsorption ends to move to open the workpiece.

[0007] Optionally, the clamping component includes: A retaining seat is provided on the base; A clamping block is disposed on the side of the clamping seat facing the workpiece and has a clamping surface that can clamp against the positioning area of ​​the workpiece.

[0008] Optionally, the clamping module includes: Two clamping rods are arranged opposite each other. The clamping component is located between the two clamping rods. One end of the clamping rod is hinged to the base and the other end extends freely. Each clamping rod is provided with at least one adsorption component for adsorbing and fixing the workpiece as the adsorption end. A driving element is connected to the clamping rod to drive the clamping rod to rotate, thereby causing the adsorption components disposed on the two clamping rods to separate or move closer to each other.

[0009] Optionally, the adsorption component includes: An adsorption seat is disposed at the free end of the clamping rod; The second adsorption element is disposed on the side of the adsorption seat facing the workpiece for adsorption and fixation with the workpiece.

[0010] Optionally, the adsorption assembly further includes: A floating seat, rotatably connected to the adsorption seat, the floating seat having an adsorption surface on the side facing the workpiece that fits against the side of the workpiece, the second adsorption element being located on the adsorption surface; and / or, The drive rod has one end connected to the drive component and the other end connected to the two clamping rods to drive the two clamping rods to rotate synchronously.

[0011] Optionally, the abutment block is provided with a first adsorption element on the side facing the workpiece, which can be adsorbed and fixed to the workpiece.

[0012] Optionally, the side of the abutment facing the workpiece is provided with a limiting groove that engages with the workpiece.

[0013] Optionally, the adsorption seat has a limiting groove on the side facing the workpiece that is inserted into the workpiece, and the opposite sidewalls of the limiting groove are respectively attached to the upper and lower sides of the workpiece.

[0014] In a second aspect, the present invention provides an assembly apparatus comprising: Machine tool; The clamping device as described in any of the first aspects is disposed on the machine base; Positioning posts, the workpiece and the product are spaced apart on the positioning posts, and the positioning posts are adjustablely positioned on the machine base; A driving mechanism is connected to the positioning column, and the driving mechanism is used to drive the positioning column to move so that the workpiece and the product carried on the positioning column correspond sequentially to the clamping device.

[0015] Optionally, the assembly equipment further includes: Multiple pressure-holding components are circumferentially spaced around the positioning post so that the pressure-holding components press against the workpiece after the workpiece is assembled into the product.

[0016] In a first aspect, in the embodiments of the present invention, during workpiece assembly, the workpiece is placed in the space enclosed by the clamping component and multiple positioning ends. The clamping component clamps against the positioning area of ​​the workpiece, restricting the movement of the workpiece. Multiple adsorption ends adsorb and fix the workpiece near the notch. Then, the clamping module is controlled to separate the multiple adsorption ends from each other. The adsorption ends will synchronously pull the workpiece. Since the workpiece itself has a certain rigidity, only when the clamping component is clamped and limited, and in conjunction with the traction of the adsorption ends, can the notch of the workpiece be opened, thereby increasing the internal space of the workpiece so that the product can be smoothly inserted into the workpiece. When the specific assembly position of the workpiece and the product corresponds, the clamping module brings the multiple adsorption ends together to assemble the inner side of the workpiece with the outer side of the product. After the assembly is firm, the adsorption ends are separated from the workpiece, thus completing the assembly of the workpiece and the product. Therefore, when using this clamping device, the workpiece can be clamped and locked in advance before being opened, and the product can be accurately inserted into the workpiece. During the product insertion process, the workpiece remains in a locked state and will not move. At this time, it is only necessary to accurately control the moving speed of the product to ensure that the workpiece and the product are accurately positioned. Then, the workpiece is assembled onto the outer side of the product, which significantly reduces the dependence on manpower in the entire assembly process, and the assembly accuracy can meet expectations. Moreover, the pressure generated during assembly remains stable, and the possibility of damage to the workpiece or product is low. At the same time, the overall work efficiency can also be effectively improved.

[0017] Secondly, in the embodiments of the present invention, before assembly, the corresponding workpieces and products are placed at designated positions on the positioning columns. At the start of assembly, the drive mechanism moves the positioning columns downwards. When the workpiece aligns with the clamping device, the clamping device grips the workpiece and opens it. The drive mechanism continues to move the positioning columns downwards, allowing the product on the positioning column to be inserted into the workpiece. The clamping device then assembles the workpiece onto the product. Therefore, when this assembly equipment is used for assembling products and workpieces, it only requires placing the product and workpiece on the positioning columns, and the entire assembly process can be completed automatically according to the program. This not only improves the overall automation level and reduces reliance on manual labor, effectively improving assembly efficiency, but also ensures accurate positioning of the product and workpiece during assembly, ensuring that the final production quality meets expectations and effectively improving the final product qualification rate.

[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 11 As shown, the present invention provides a clamping device and an assembly equipment.

[0025] Reference Figures 1 to 4 The clamping device is used to grasp the workpiece 10 and assemble it onto the outside of the product 20 after opening the notch 101 of the workpiece 10. It includes a base 1, a clamping component 2, and a clamping module 3. The clamping component 2 is disposed on the base 1 to clamp against the positioning area 102 of the workpiece 10; the clamping module 3 is disposed on the base 1 and has multiple adsorption ends, which are distributed on both sides of the clamping component 2 to adsorb the part of the workpiece 10 near the notch 101. The clamping module 3 can drive the multiple adsorption ends to move away from each other to open the workpiece 10.

[0026] During the assembly of workpiece 10, workpiece 10 is placed in the space enclosed by the clamping component 2 and multiple adsorption ends. The clamping component 2 is clamped against the positioning area 102 of workpiece 10, restricting the movement of workpiece 10. Multiple adsorption ends are adsorbed and fixed near the notch 101 of workpiece 10. Then, the clamping module 3 is controlled to drive the multiple adsorption ends to move. The adsorption ends will synchronously pull workpiece 10. Since workpiece 10 has a certain rigidity, only when the clamping component 2 is clamped and limited, and the adsorption ends are pulled, can the notch 101 of workpiece 10 be opened, thereby increasing the internal space of workpiece 10 so that product 20 can be smoothly taken out and inserted into workpiece 10. When the specific assembly position of workpiece 10 and product 20 corresponds, the clamping module 3 brings the multiple adsorption ends together to assemble the inner side of workpiece 10 with the outer side of product 20. After the assembly is firm, the adsorption ends are separated from workpiece 10, thus completing the assembly of workpiece 10 and product 20. Therefore, when using this clamping device, the workpiece 10 can be clamped and locked in advance, and then the workpiece 10 can be opened. The product 20 can then be accurately inserted into the workpiece 10, and the workpiece 10 remains in a locked state during the insertion process and will not move. At this time, it is only necessary to accurately control the moving speed of the product 20 to make the workpiece 10 and the product 20 accurately positioned. Then, the workpiece 10 is assembled onto the outer side of the product 20, which significantly reduces the dependence on manpower in the entire assembly process, and the assembly accuracy can meet expectations. Moreover, the pressure generated during assembly remains stable, and the possibility of damage to the workpiece 10 or the product 20 is low. At the same time, the overall work efficiency can also be effectively improved.

[0027] Specifically, the base 1 is flat and can be fixed to a designated platform or slidably mounted onto a designated platform via the translation component 11. The position of the base 1 can be adjusted via the translation component 11, thereby adjusting the positions of the abutment component 2 and the clamping module 3 mounted on the base 1. In this embodiment, the base 1 is slidably arranged on the machine base 4 of the assembly equipment via the translation component 11.

[0028] The base 1 has a space for accommodating the workpiece 10 and the product 20. The workpiece 10 and product 20 can be sequentially fed into this space by individual robotic arms, or they can be positioned at intervals using a specific positioning structure before being sequentially fed into the space. The product 20 can be a rotating structure or another shape. The outer diameter of the top and bottom ends of the product 20 is larger, while the outer diameter of the middle part is smaller, to accommodate the workpiece 10. The workpiece 10 can be a ring-shaped structure or a polygonal frame structure, with a notch 101 on one side to allow it to open so that the inner dimension of the workpiece 10 is larger than the outer diameter of the top and bottom ends of the product 20, ensuring that the product 20 can be smoothly inserted into the workpiece 10. In this embodiment, the product 20 is a coil frame in a ring-shaped electronic component such as a toroidal inductor, transformer, or voice coil, and the workpiece 10 is a steel ring fitted around the outside of the coil frame. The outer side of the coil frame has an adhesive layer that can bond and fix the workpiece 10 to the steel ring after it is fitted.

[0029] The shape of the aforementioned space is designed to correspond to the shapes of the actual product 20 and workpiece 10. A clamping component 2 and a holding module 3 are arranged at the edge of this space. The clamping component 2 is fixed to the base 1. The workpiece 10 enters the space in a designated position, ensuring that the positioning area 102 of the workpiece 10 corresponds to the clamping component. Movement of the base 1 pushes one end of the clamping component 2 to press against the surface of the workpiece 10. In this embodiment, to facilitate the subsequent opening of the workpiece 10, the positioning area 102 of the workpiece 10 is aligned with the notch 101 of the workpiece 10. In other embodiments, depending on the shape of the workpiece 10 and the position of the notch 101, the positioning area 102 can be set at other locations. To facilitate the correspondence between the workpiece 10 and the clamping component 2, the clamping component 2 is positioned at the center of the base 1.

[0030] Reference Figure 5 Optionally, the clamping assembly 2 includes a clamping seat 21 and a clamping block 22. The clamping seat 21 is disposed on the base 1; the clamping block 22 is disposed on the side of the clamping seat 21 facing the workpiece 10 and has a clamping surface that can clamp against the positioning area 102 of the workpiece 10.

[0031] Specifically, the abutment 21 is block-shaped, with an ear seat on one side of its bottom surface, which is fixedly connected to the base 1, and the other side of its bottom surface extends into the aforementioned space. Abutment block 22 is formed by a partial protrusion on the side of the abutment 21. The side of the abutment block 22 facing the workpiece 10 serves as an abutment surface that can be adapted to the side of the workpiece 10. In this embodiment, the workpiece 10 is a steel ring with an arc-shaped outer surface, and the abutment surface is an arc shape that fits against the surface of the steel ring.

[0032] The clamping block 22 is fixed to the base 1 by the clamping seat 21, and the clamping surface of the clamping block 22 can be set facing the workpiece 10. After the workpiece 10 is placed in the space, the clamping block 22 can be moved closer to the workpiece 10 as the base 1 moves. When the clamping surface is in contact with the surface of the workpiece 10, the clamping block 22 can be clamped to the workpiece 10, thereby limiting the position of the workpiece 10.

[0033] Optionally, the abutting block 22 is provided with a first adsorption element 23 on the side facing the workpiece 10, which can be adsorbed and fixed with the workpiece 10.

[0034] Specifically, the first adsorption element 23 can be a vacuum suction cup, or it can be an electromagnet or a magnetic block, etc. It is disposed on the abutting surface. When the abutting surface is in contact with the workpiece 10, it can be adsorbed and fixed to the workpiece 10, thereby further improving the limiting effect on the workpiece 10. In this embodiment, the first adsorption element 23 is a magnetic block, and multiple magnetic blocks can be distributed at intervals around the circumference of the workpiece 10.

[0035] Optionally, the side of the abutment 21 facing the workpiece 10 is provided with a limiting groove 24 that engages with the workpiece 10.

[0036] Specifically, locking blocks are fixedly installed on the upper and lower sides of the clamping seat 21, with both blocks protruding from the clamping block 22. The protruding portions correspond vertically to form limiting grooves 24. The width of the limiting grooves 24 is slightly larger than the height of the workpiece 10, and the sidewalls of the limiting grooves 24 can also protrude partially to fit the shape of the workpiece 10. The fixed connections of each structure within the clamping assembly 2 described above can be achieved by any method such as welding, bonding, riveting, or bolting. This invention does not limit the specific method used.

[0037] By setting a limiting groove 24, when the abutting surface is in contact with the surface of the workpiece 10, the workpiece 10 will be partially inserted into the limiting groove 24. The side wall of the limiting groove 24 can be in contact with the upper and lower sides of the workpiece 10, thereby restricting the movement of the workpiece 10 in the vertical direction, so as to further improve the limiting effect on the workpiece 10.

[0038] After the clamping component 2 clamps and limits the workpiece 10, the clamping module 3 can be used to adsorb the workpiece 10. Multiple adsorption ends of the clamping module 3 can be evenly distributed on both sides of the clamping component 2, and the adsorption ends can adsorb and fix the workpiece 10 near the notch 101. The clamping module 3 rotates partially to move the adsorption ends distributed on both sides of the clamping component 2 away from each other. The clamping module 3 can also use two sets of drive structures to drive the adsorption ends distributed on both sides of the clamping component 2 to translate, making the adsorption ends on both sides of the clamping component 2 move away from each other. Because the workpiece 10 is partially clamped and limited by the clamping component 2, when it is pulled at the notch 101, the workpiece 10 can only deform and cannot shift, thus allowing the workpiece 10 to be smoothly pulled open at the notch 101. It should be understood that the layout of the multiple adsorption ends on both sides of the clamping component 2 can be designed according to the actual shape of the workpiece 10, as long as it can smoothly clamp and open the workpiece 10, and is not limited to the case described above where the multiple adsorption ends are evenly distributed on both sides of the clamping component 2.

[0039] Reference Figure 6 Optionally, the clamping module 3 includes a driving member 31 and two opposing clamping rods 32. The pressing component 2 is located between the two clamping rods 32. One end of the clamping rod 32 is hinged to the base 1, and the other end extends freely. Each clamping rod 32 is provided with at least one adsorption component 33 for adsorbing and fixing the workpiece 10 as an adsorption end. The driving member 31 is connected to the clamping rod 32 to drive the clamping rod 32 to rotate so that the adsorption components 33 provided on the two clamping rods 32 are separated from each other or brought closer together.

[0040] Specifically, the clamping rod 32 includes an integrally formed rotating section 321, a driving section 322, and an adsorption section 323. The rotating section 321, the driving section 322, and the adsorption section 323 are all in the same plane, but their extension directions are different. The specific extension direction can be designed according to the actual installation space and rotation range, and this invention does not limit it. By designing the clamping rod 32 as a multi-segment structure, the installation space on the top wall of the base 1 is fully released, so that the clamping component 2 and other structures can be arranged more compactly, effectively improving the space utilization rate.

[0041] The rotating section 321 is rotatably connected to the base 1 via a rotating rod, which serves as the rotation center of the entire clamping rod 32. The driving section 322 is rotatably connected to the output end of the driving component 31. Each clamping rod 32's driving section 322 can be equipped with a corresponding driving component 31, or one driving component 31 can be connected to two driving sections 322 simultaneously via a linkage mechanism. The driving component 31 can be a linear motor module or an electric slide cylinder, which can be selected according to the actual driving requirements. The adsorption section 323 extends along the edge of the space, and an adsorption component 33 is installed at the end of the adsorption section 323 away from the rotating section 321. The installation position of the adsorption component 33 can correspond to the part of the workpiece 10 near the notch 101. The adsorption component 33 can be adsorbed and fixed to the outer wall of the workpiece 10 by vacuum adsorption or magnetic attraction. In this embodiment, each clamping rod 32 is provided with one adsorption component 33. In other embodiments, multiple adsorption components 33 can be distributed at intervals on each clamping rod 32.

[0042] Once the clamping component 2 clamps the workpiece 10, the driving component 31 drives the two clamping rods 32 to rotate and move closer to each other. The adsorption component 33 on the clamping rods 32 approaches the workpiece 10 and forms an adsorption fixation after contacting the surface of the workpiece 10. Then, the driving component 31 drives the two clamping rods 32 to separate from each other, and the adsorption component 33 pulls the notch 101 of the workpiece 10, causing the workpiece 10 to open. Since the opposite part of the notch 101 of the workpiece 10 is clamped and limited by the clamping component 2, the notch 101 of the workpiece 10 will be gradually pulled open under the traction of the adsorption component 33, increasing the internal space of the workpiece 10. The specific opening range can be precisely controlled according to the actual assembly requirements to ensure that the workpiece 10 can open smoothly without damaging the workpiece 10.

[0043] Reference Figure 1 To further limit the opening range of the workpiece 10, a limiting block 12 is provided on the top wall of the base 1. The limiting block 12 is fixed at the position of the base 1 near the adsorption section 323 and is located near the adsorption assembly 33. The limiting block 12 is threadedly connected to a limiting bolt 13. The end face of the limiting bolt 13 is opposite to the side of the clamping rod 32 away from the workpiece 10. The distance between the limiting bolt 13 and the clamping rod 32 is the maximum range of rotation that the clamping rod 32 can rotate, which is also the maximum range that the workpiece 10 can open. This ensures that the workpiece 10 will not exceed the maximum threshold and be damaged during the opening process.

[0044] Reference Figure 6 Optionally, the clamping module 3 includes a drive rod 34. One end of the drive rod 34 is connected to the drive member 31, and the other end is connected to two clamping rods 32 to drive the two clamping rods 32 to rotate synchronously.

[0045] Specifically, the horizontal cross-section of the drive rod 34 is U-shaped. The middle of its horizontal arm is connected to the output end of the drive member 31 via an ear seat, and the ends of its two vertical arms are rotatably connected to the drive sections 322 of the two clamping rods 32, respectively. This way, only one drive member 31 is needed. When the drive member 31 is running, it can drive the two clamping rods 32 to rotate synchronously via the drive rod 34. It should be understood that the drive rod 34 can also be replaced with other linkage mechanisms or pulley mechanisms, etc., depending on the actual installation space and transmission requirements.

[0046] Reference Figure 7 and Figure 8 Optionally, the adsorption assembly 33 includes an adsorption seat 331 and a second adsorption member 332. The adsorption seat 331 is disposed at the free end of the clamping rod 32; the second adsorption member 332 is disposed on the side of the adsorption seat 331 facing the workpiece 10 for adsorption and fixation with the workpiece 10.

[0047] Specifically, the adsorption seat 331 is inserted into the clamping rod 32, and the two are fixedly connected. To adapt to different workpieces 10, the position of the adsorption seat 331 on the clamping rod 32 can be adjusted. For example, the adsorption seat 331 can be located at the end of the free end of the clamping rod 32, so that the two adsorption components 33 and one clamping component 2 form an equilateral triangle layout. The adsorption seat 331 can also be located in the middle of the clamping rod 32, so that the two adsorption components 33 and one clamping component 2 form an isosceles triangle layout. It should be understood that other shapes can also be formed, which can be designed according to the actual shape of the workpiece 10. In this embodiment, a groove is provided on the bottom surface of the adsorption seat 331, and a portion of the clamping rod 32 is inserted into the groove and slides in cooperation with the groove. Multiple bolts and other fasteners are provided on the top wall of the adsorption seat 331. The fasteners can be connected to the clamping rod 32 to fix the adsorption seat 331 on the clamping rod 32.

[0048] A second adsorption element 332 is provided on the side of the adsorption seat 331 away from the clamping rod 32. The second adsorption element 332 can be a vacuum suction cup, an electromagnet, or a magnetic block, etc., which can effectively form an adsorption fixation with the workpiece 10. In this embodiment, the second adsorption element 332 is a magnetic block, and multiple second adsorption elements 332 are distributed along the circumference of the workpiece 10 to improve the connection strength between the adsorption assembly 33 and the workpiece 10.

[0049] After the clamping rod 32 pushes the adsorption seat 331 and the second adsorption member 332 close to the workpiece 10, the second adsorption member 332 will adhere to the surface of the workpiece 10 to form an adsorption fixation. When the clamping rod 32 rotates in the opposite direction, it will drive the adsorption seat 331 and the second adsorption member 332 away from the workpiece 10. At this time, the second adsorption member 332 continues to adsorb the workpiece 10, so that the notch 101 of the workpiece 10 can be smoothly pulled, and the workpiece 10 can be opened smoothly.

[0050] Optionally, the adsorption assembly 33 further includes a floating seat 333. The floating seat 333 is rotatably connected to the adsorption seat 331. The side of the floating seat 333 facing the workpiece 10 has an adsorption surface that fits against the side of the workpiece 10, and the second adsorption member 332 is located on the adsorption surface.

[0051] Specifically, the floating seat 333 is located in front of the adsorption seat 331, and one end of it has an extension that extends into the adsorption seat 331 and is rotatably connected to the adsorption seat 331. The rotation direction is the circumferential direction of the workpiece 10. The other end of the adsorption seat 331 is provided with an adsorption surface, the shape of which is adapted to the shape of the workpiece 10. The second adsorption element 332 is provided on the adsorption surface.

[0052] By setting the floating seat 333, when the workpiece 10 is opened, the workpiece 10 itself deforms. For example, the ring-shaped workpiece 10 may become an elliptical workpiece 10. At this time, a tangential load will be generated between the second adsorption member 332 and the workpiece 10. Under the action of this load, the floating seat 333 will be pushed to swing, thereby buffering the stress caused by the load. This ensures that the second adsorption member 332 will not generate additional stress that would damage the workpiece 10 while adsorbing and fixing the workpiece 10, thus effectively improving the protection effect of the workpiece 10.

[0053] Optionally, the adsorption seat 331 has a limiting groove 334 on the side facing the workpiece 10, which is inserted and engaged with the workpiece 10. The opposite sidewalls of the limiting groove 334 are respectively attached to the upper and lower sides of the workpiece 10.

[0054] Specifically, limiting parts are provided on the upper and lower sides of the adsorption seat 331. Both limiting parts protrude partially from the floating seat 333 to form limiting grooves 334. The width of the limiting grooves 334 is slightly greater than the height of the workpiece 10, so that the opposite sidewalls of the limiting grooves 334 are in contact with the upper and lower sides of the workpiece 10. When the second adsorption member 332 is adsorbed and fixed to the workpiece 10, the limiting grooves 334 can simultaneously restrict the vertical movement of the workpiece 10, further reducing the possibility of the workpiece 10 shifting.

[0055] Reference Figures 9 to 11 The assembly equipment includes a machine base 4, positioning columns 5, a drive mechanism 6, and the clamping device mentioned above. The clamping device is disposed on the machine base 4; the workpiece 10 and the product 20 are spaced apart on the positioning columns 5, and the positioning columns 5 are adjustablely disposed on the machine base 4; the drive mechanism 6 is connected to the positioning columns 5, and the drive mechanism 6 is used to drive the positioning columns 5 to move so that the workpiece 10 and the product 20 on the positioning columns 5 are sequentially aligned with the clamping device.

[0056] Before assembly, both workpiece 10 and product 20 are placed at designated positions on the positioning post 5. At the start of assembly, the drive mechanism 6 moves the positioning post 5 downwards. When workpiece 10 aligns with the clamping device, the clamping device picks up workpiece 10 and opens it. The drive mechanism 6 continues to move the positioning post 5 downwards, allowing product 20 on the positioning post 5 to be inserted into workpiece 10. The clamping device then assembles workpiece 10 onto product 20. Therefore, when assembling product 20 and workpiece 10, this assembly equipment only requires placing both on the positioning post 5; the entire assembly process is automated according to the program. This not only improves the overall automation level and reduces reliance on manual labor, effectively increasing assembly efficiency, but also ensures precise positioning of product 20 and workpiece 10 during assembly, ensuring that the final production quality of product 20 meets expectations and effectively improving the pass rate of the final product 20.

[0057] Specifically, the base 1 is slidably connected to the machine base 4 via the translation component 11, and a positioning column 5 is set in the middle of the machine base 4. The positioning column 5 is elongated, and installation positions for the product 20 and the workpiece 10 can be reserved on the positioning column 5 respectively. The top of the positioning column 5 is closed by the detachable pressure cover 51. When the product 20 and the workpiece 10 are installed on the positioning column 5 in sequence and at intervals, the pressure cover 51 can be removed, and then installed again after installation. The workpiece 10 is located below the product 20, and multiple vacuum suction holes 52 are arranged around the position corresponding to the workpiece 10 to adsorb the workpiece 10 onto the positioning column 5. A support platform 53 is set at the position corresponding to the product 20, and the product 20 can be fixed by fitting it onto the support platform 53.

[0058] The drive mechanism 6 may include a lifting module 61 and a rotating module 62. The lifting module 61 can drive the rotating module 62 and the positioning column 5 to move up and down as a whole, while the rotating module 62 is connected to the positioning column 5 and can drive the positioning column 5 to rotate, thereby adjusting the angle between the product 20 and the workpiece 10. Both the lifting module 61 and the rotating module 62 can be driven by a motor, cylinder, or electric cylinder, etc., in conjunction with a gear set or lead screw, etc., to achieve the lifting and rotation drive. The specific configuration can refer to the prior art, which is not the inventive point of this invention and will not be described in detail here.

[0059] Optionally, the assembly equipment also includes a plurality of pressure-holding components 7. The plurality of pressure-holding components 7 are arranged circumferentially around the positioning post 5 so that after the product 20 is assembled on the workpiece 10, the pressure-holding components 7 press against the workpiece 10.

[0060] Specifically, the pressure-holding assembly 7 includes a pressure-holding drive and a pressure-holding part disposed at the output end of the pressure-holding drive. The pressure-holding drive can be a cylinder or a motor, etc., and the pressure-holding part has a block-shaped or plate-shaped structure. The pressure-holding drive can drive the pressure-holding part to approach the positioning post 5, so that after the product 20 is mounted on the workpiece 10, the pressure-holding part presses against the workpiece 10, making the workpiece 10 continuously adhere to the product 20, and the pressure-holding part is withdrawn after the adhesive between the product 20 and the workpiece 10 solidifies. In this embodiment, in order to further optimize the spatial layout, one pressure-holding assembly 7 is disposed on the machine base 4, while the remaining pressure-holding assemblies 7 are distributed on the base 1 of the clamping device. A protective pad, such as a rubber pad, can also be disposed on the side of the pressure-holding part facing the workpiece 10 to avoid damage to the workpiece 10 or the product 20.
