Description

Technical Field

[0001] This application relates to the field of pressing equipment technology, and more specifically to a pressing device. Background Technology

[0002] In the assembly of electronic products, it is often necessary to attach multiple small components to larger components. To improve the connection strength between the small components and the large components, a pressing process is required after the small components are attached to the large components. However, due to the structural differences between the various small components, their heights vary after being attached to the large components, and the required pressing pressures also differ. Traditional pressing methods use a different pressing device for each small component. This method not only requires multiple pressing devices, significantly increasing production costs, but also necessitates multiple pressing operations, resulting in extended processing time and low work efficiency. Utility Model Content

[0003] In view of the above, it is necessary to propose a pressing device that can press different workpieces simultaneously, with low production cost, high operating efficiency and good pressing effect.

[0004] This application provides a pressing device for pressing a first workpiece and a plurality of second workpieces, the plurality of second workpieces being disposed above the first workpiece. The device includes: a positioning mechanism for supporting and positioning the first workpiece; and a pressing mechanism comprising a driving component, an elastic pressing component, and a fixed pressing component. The driving component includes a pressing driving member and a connecting member. The pressing driving member is connected to the positioning mechanism, and the connecting member is connected to the pressing driving member. The elastic pressing component is elastically connected to the connecting member in a vertical direction. The fixed pressing component is fixedly connected to the connecting member and spaced apart from the elastic pressing component. The elastic pressing component and the fixed pressing component correspond to the plurality of second workpieces respectively. The pressing driving member drives the connecting member to move toward the second workpiece, so that the elastic pressing component and the fixed pressing component abut against the corresponding second workpiece, thereby pressing the first workpiece and the plurality of second workpieces.

[0005] The aforementioned pressing device precisely positions the first workpiece using a positioning mechanism, and drives the elastic pressing component and the fixed pressing component within the pressing mechanism to simultaneously press multiple second workpieces. The elastic pressing component can adapt to second workpieces of different heights and shapes, providing flexible pressing; the fixed pressing component ensures the stability of the pressing process. This pressing device not only solves the problems of varying heights and pressing requirements of different second workpieces, but also significantly improves production efficiency, reduces equipment investment and maintenance costs, and enhances product quality by pressing multiple second workpieces at once.

[0006] In some embodiments, the elastic pressing assembly includes an elastic pressing member and an elastic member. The elastic pressing member is slidably connected to the connector in a vertical direction. One end of the elastic pressing member extends out of the connector from the side opposite to the pressing drive member. The two ends of the elastic member abut against the elastic pressing member and the connector, respectively.

[0007] In some embodiments, the fixed pressing assembly includes a fixed pressing member, which is fixedly connected to the connector and spaced apart from the elastic pressing member. One end of the fixed pressing member extends out of the connector from the side opposite to the pressing drive member, and the length of the fixed pressing member extending out of the connector is less than the length of the elastic pressing member extending out of the connector.

[0008] In some embodiments, the elastic pressing assembly further includes a first flexible sleeve, which is sleeved on one end of the elastic pressing member that extends out of the connector; the fixed pressing assembly further includes a second flexible sleeve, which is sleeved on one end of the fixed pressing member that extends out of the connector.

[0009] In some embodiments, the pressing device further includes a heating mechanism, which is detachably connected to the positioning mechanism and abuts against the side of the first workpiece away from the plurality of second workpieces.

[0010] In some embodiments, the pressing device further includes a force measuring mechanism, which is detachably connected to the positioning mechanism and is disposed opposite to the elastic pressing member and the fixed pressing member. The force measuring mechanism is used to detect the pressure applied by the elastic pressing member and the fixed pressing member.

[0011] In some embodiments, the force measuring mechanism includes a force sensor, a first detection block, and a second detection block. The force sensor is detachably connected to the positioning mechanism and is disposed opposite to the elastic pressing member and the fixed pressing member. The first detection block and the second detection block are detachably disposed on the force sensor. The first detection block is disposed opposite to the elastic pressing member, and the second detection block is disposed opposite to the fixed pressing member. The pressing drive member drives the connecting member to move toward the force sensor, so that the elastic pressing member abuts against the first detection block, or the fixed pressing member abuts against the second detection block, thereby allowing the force sensor to detect the pressure applied by the elastic pressing member or the fixed pressing member.

[0012] In some embodiments, the positioning mechanism includes a positioning seat, a plurality of limiting members, and a plurality of pushing members.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0023] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0024] Please see Figure 1 This application provides a pressing device 100 for pressing a first workpiece 200 and a plurality of second workpieces 300. The plurality of second workpieces 300 are disposed on the upper side of the first workpiece 200. The first workpiece 200 can be a plate-shaped or block-shaped structure, such as the back cover, middle plate, or glass panel of an electronic product, such as a mobile phone or tablet. The second workpieces 300 can be small structural components. In this application embodiment, the second workpieces 300 are pre-attached to the first workpiece 200. The second workpieces 300 and the first workpiece 200 can be attached together using double-sided tape, glue, etc. The number of second workpieces 300 can be two, three, four, etc. The pressing device 100 includes a positioning mechanism 10 and a pressing mechanism 20.

[0025] Specifically, please see Figure 1 and Figure 2The positioning mechanism 10 is used to support and position the first workpiece 200. Since the second workpiece 300 is attached to the first workpiece 200, the positioning mechanism 10 also positions the second workpiece 300 when positioning the first workpiece 200.

[0026] The pressing mechanism 20 includes a driving component 21, an elastic pressing component 22, and a fixed pressing component 23. The driving component 21 includes a pressing driving member 211 and a connecting member 212. The pressing driving member 211 is connected to the positioning mechanism 10, and the connecting member 212 is connected to the pressing driving member 211. The elastic pressing component 22 is elastically connected to the connecting member 212 in the vertical direction. The fixed pressing component 23 is fixedly connected to the connecting member 212 and is spaced apart from the elastic pressing component 22. The elastic pressing component 22 and the fixed pressing component 23 correspond to a plurality of second workpieces 300 respectively. The pressing driving member 211 drives the connecting member 212 to move toward the second workpiece 300 so that the elastic pressing component 22 and the fixed pressing component 23 abut against the corresponding second workpiece 300, thereby pressing the first workpiece 200 and the plurality of second workpieces 300.

[0027] The pressing drive component 211 can be a cylinder or other driving component. The pressing drive component 211 is connected to the positioning mechanism 10, and its driving end faces the positioning mechanism 10. The connecting component 212 can be a block structure, and its interior can have multiple receiving slots (not shown) to accommodate the elastic pressing component 22 and the fixed pressing component 23. In this embodiment, multiple elastic pressing components 22 can be provided, such as two or three, while only one fixed pressing component 23 can be provided. The sum of the number of elastic pressing components 22 and fixed pressing components 23 is consistent with the number of the second workpiece 300.

[0028] The elastic pressing component 22 is elastically connected to the connector 212 in the vertical direction, and can adapt to the second workpiece 300 of different heights. During the pressing process, the elastic pressing component 22 can automatically adjust according to the actual height of the second workpiece 300 to ensure a stable pressing force. The fixed pressing component 23 can provide a stable pressing force to its corresponding second workpiece 300, and when the fixed pressing component 23 abuts against the second workpiece 300, it can also play a limiting role to prevent the pressing drive component 211 from running excessively, which would cause the elastic pressing component 22 to press the second workpiece 300 with excessive pressure.

[0029] The pressing device 100 provided in this application embodiment precisely positions the first workpiece 200 using a positioning mechanism 10, and drives the elastic pressing component 22 and the fixed pressing component 23 through the driving component 21 in the pressing mechanism 20 to simultaneously press multiple second workpieces 300. The elastic pressing component 22 can adapt to second workpieces 300 of different heights and shapes, providing flexible pressing; the fixed pressing component 23 ensures the stability of the pressing process. The pressing device 100 provided in this application embodiment not only solves the problems of height differences and varying pressing requirements of different second workpieces 300, but also significantly improves production efficiency, reduces equipment investment and maintenance costs, and enhances product quality by pressing multiple second workpieces 300 at once.

[0030] In some embodiments, see Figure 1 and Figure 2 The elastic pressing assembly 22 includes an elastic pressing member 221 and an elastic member 222. The elastic pressing member 221 is slidably connected to the connector 212 in a vertical direction. One end of the elastic pressing member 221 extends out of the connector 212 and faces away from the pressing drive member 211. The two ends of the elastic member 222 abut against the elastic pressing member 221 and the connector 212, respectively. The elastic pressing member 221 can be a columnar or rod-shaped structure, and the elastic member 222 can be an elastic structure such as a spring. In this embodiment, the receiving groove in the connector 212 corresponding to the elastic pressing member 221 can be provided with a limiting step, and the elastic pressing member 221 can be provided with a corresponding limiting protrusion to prevent the elastic pressing member 221 from moving out of the connector 212. The elastic element 222 can be sleeved on the elastic pressing element 221. The two ends of the elastic element 222 can respectively abut against the limiting protrusion and the connecting element 212 of the elastic pressing element 221, which can enhance the stability of the elastic element 222 when it pushes against the movement of the elastic pressing element 221.

[0031] During pressing, the elastic pressing member 221 abuts against the second workpiece 300, compressing the elastic member 222. The elastic member 222 applies pressure to the elastic pressing member 221, thereby pressing the second workpiece 300. The elastic member 222 also provides effective cushioning for the pressing process. At the moment of pressing, the elastic member 222 can absorb part of the impact force, preventing rigid contact from damaging the second workpiece 300. The elastic member 222 acts uniformly on the elastic pressing member 221. During the pressing process, the elastic pressing member 221 can more evenly transmit pressure to the surface of the second workpiece 300. For some irregularly shaped second workpieces 300, the uniform pressure distribution can ensure that the fit between the entire second workpiece 300 and the first workpiece 200 is consistent, thereby ensuring the reliability of the connection.

[0032] In some embodiments, see Figure 1 and Figure 2The fixed pressing assembly 23 includes a fixed pressing member 231, which is fixedly connected to the connector 212 and spaced apart from the elastic pressing member 221. One end of the fixed pressing member 231 extends out of the connector 212 from the side opposite to the pressing drive member 211, and the length of the fixed pressing member 231 extending out of the connector 212 is less than the length of the elastic pressing member 221 extending out of the connector 212. The fixed pressing member 231 can be rod-shaped or columnar. The fixed pressing member 231 is fixedly connected to the connector 212, providing a stable and reliable pressure support point. When the pressing drive member 211 drives the fixed pressing member 231 to move a preset distance toward the second workpiece 300 through the connector 212, the fixed pressing member 231 abuts against the second workpiece 300 and applies a preset pressure to the second workpiece 300, thereby completing the pressing. The length of the fixed pressing member 231 extending out of the connecting member 212 is less than the length of the elastic pressing member 221 extending out of the connecting member 212. This allows the elastic pressing member 221 to abut against the corresponding second workpiece 300 before the fixed pressing member 231 during the pressing process. When the fixed pressing member 231 abuts against the second workpiece 300, the elastic pressing member 221 compresses the elastic member 222, and the elastic member 222 applies a force to the elastic pressing member 221, so that the elastic pressing member 221 presses against the corresponding second workpiece 300 with a preset pressure.

[0033] The fixed pressing component 231 and the elastic pressing component 221 have a clear division of labor. During one driving process of the pressing drive component 211, the two can simultaneously and efficiently press the second workpiece 300 with different requirements. There is no need to adjust the pressing method or change the pressing tool for different workpieces multiple times, which reduces the pressing steps and time and improves production efficiency.

[0034] In some embodiments, see Figure 1 and Figure 2 The elastic pressing assembly 22 further includes a first flexible sleeve 223, which is sleeved on one end of the elastic pressing member 221 that extends out of the connecting member 212. The fixed pressing assembly 23 further includes a second flexible sleeve 232, which is sleeved on one end of the fixed pressing member 231 that extends out of the connecting member 212. Both the first flexible sleeve 223 and the second flexible sleeve 232 can be made of materials such as urethane. By setting the first flexible sleeve 223 and the second flexible sleeve 232, rigid contact between the elastic pressing member 221 and the fixed pressing member 231 and the second workpiece 300 can be avoided, preventing scratches and wear on the workpiece surface, which is beneficial to improving production yield.

[0035] In some embodiments, see Figure 1 and Figure 3The pressing device 100 also includes a heating mechanism 30, which is detachably connected to the positioning mechanism 10. The heating mechanism 30 abuts against the side of the first workpiece 200 opposite to the plurality of second workpieces 300. The heating mechanism 30 is used to heat the first workpiece 200 and the plurality of second workpieces 300. The heating mechanism 30 may include structures such as a heater, a heating block, and a heat insulation block. The heater heats the heating block, which abuts against the first workpiece 200 and transfers heat to the second workpieces 300 on the first workpiece 200, thereby heating both the first workpiece 200 and the second workpiece 300. Heating the first workpiece 200 and the second workpiece 300 through the adding mechanism facilitates the curing of adhesives or other substances between the first workpiece 200 and the second workpiece 300, improving the pressing efficiency.

[0036] In some embodiments, see Figure 1 , Figure 2 and Figure 4 The pressing device 100 also includes a force measuring mechanism 40, which is detachably connected to the positioning mechanism 10. The force measuring mechanism 40 is positioned opposite to the elastic pressing member 221 and the fixed pressing member 231. The force measuring mechanism 40 is used to detect the pressure applied by the elastic pressing member 221 and the fixed pressing member 231. By setting the force measuring mechanism 40, the pressure applied by the elastic pressing member 221 and the fixed pressing member 231 can be detected before pressing and after a preset working time, thereby enabling precise control of the pressure applied by the elastic pressing member 221 and the fixed pressing member 231 to the second workpiece 300 during the pressing process. This ensures that each second workpiece 300 receives appropriate pressure during pressing, avoiding insufficient pressure leading to weak adhesion or excessive pressure leading to damage to the second workpiece 300.

[0037] It is understood that both the heating mechanism 30 and the force measuring mechanism 40 correspond to the pressing mechanism 20, therefore, the heating mechanism 30 and the force measuring mechanism 40 can be connected to the same position in the positioning mechanism 10. Before pressing, when testing the pressure applied by the elastic pressing member 221 and the fixed pressing member 231, the heating mechanism 30 is removed, and the force measuring mechanism 40 is installed in the positioning mechanism 10, after which pressure testing can be performed. After testing, the force measuring mechanism 40 can be removed, and the heating mechanism 30 can be installed in the positioning mechanism 10, after which pressing operations can be performed.

[0038] In some embodiments, see Figure 1 , Figure 2 and Figure 4The force measuring mechanism 40 includes a force sensor 41, a first detection block 42, and a second detection block 43. The force sensor 41 is detachably connected to the positioning mechanism 10 and is positioned opposite to the elastic pressing member 221 and the fixed pressing member 231. The first detection block 42 and the second detection block 43 are both detachably mounted on the force sensor 41. The first detection block 42 is positioned opposite to the elastic pressing member 221, and the second detection block 43 is positioned opposite to the fixed pressing member 231. The pressing drive member 211 drives the connecting member 212 to move toward the force sensor 41, so that the elastic pressing member 221 abuts against the first detection block 42, or the fixed pressing member 231 abuts against the second detection block 43, thereby allowing the force sensor 41 to detect the pressure applied by the elastic pressing member 221 or the fixed pressing member 231. By setting the force sensor 41, pressure can be detected. By setting the first detection block 42 and the second detection block 43, the positions of multiple second workpieces 300 can be simulated, thereby improving the accuracy of pressure detection.

[0039] Specifically, before testing, the heating mechanism 30 is removed from the positioning mechanism 10, and then the force gauge 41 is installed in the position corresponding to the pressing mechanism 20. During testing, the second detection block 43 is placed on the force gauge 41, and the second detection block 43 is aligned with the fixed pressing member 231. At this time, the height of the second detection block 43 is consistent with the height of the second workpiece 300 to be pressed by the fixed pressing member 231. The pressing drive member 211 drives the fixed pressing member 231 to abut against the second detection block 43, and the pressure generated by the fixed pressing member 231 can be detected. If the pressure of the fixed pressing member 231 is too high or too low, the pressure of the fixed pressing member 231 can be adjusted by adjusting the driving pressure of the pressing drive member 211 or the length of travel of the output end of the pressing drive member 211.

[0040] Then, the first detection block 42 and the second detection block 43 are simultaneously placed on the force measuring device 41, with the first detection block 42 corresponding to the position of the elastic pressing member 221 and the second detection block 43 corresponding to the position of the fixed pressing member 231. If there are multiple elastic pressing members 221, multiple first detection blocks 42 can be set, or different stepped surfaces can be set on the first detection blocks 42 to simulate the height position of each second workpiece 300. The pressing drive member 211 drives the elastic pressing member 221 and the fixed pressing member 231 to simultaneously abut against the corresponding first detection block 42 and the second detection block 43, thereby detecting the pressure of the elastic pressing member 221. If the pressure of the elastic pressing member 221 is too high, the force exerted by the elastic member 222 on the elastic pressing member 221 can be reduced by replacing the elastic member 222 or cutting off a certain length of the elastic member 222; if the pressure of the elastic pressing member 221 is too low, it can be adjusted by replacing the elastic member 222.

[0041] In some embodiments, see Figure 1 , Figure 3 and Figure 4 The positioning mechanism 10 includes a positioning seat 11, multiple limiting members 12, and multiple pushing members 13. The positioning seat 11 is provided with a loading area 111 for supporting the first workpiece 200. The multiple limiting members 12 are fixedly connected to the positioning seat 11 and are located on two adjacent sides of the loading area 111. The multiple pushing members 13 are connected to the positioning seat 11 and are located on two other adjacent sides of the loading area 111. The pushing members 13 are used to push the first workpiece 200 against the corresponding limiting member 12 to position the first workpiece 200. The positioning seat 11 can be a plate-shaped structure, the limiting members 12 can be column-shaped or block-shaped structures, and the number of limiting members 12 can be four, six, etc. The pushing members 13 can be a combination of a cylinder and a block structure, and the number of pushing members 13 can be four, six, etc.

[0042] The positioning mechanism 10 carries the first workpiece 200 through the loading area 111 on the positioning seat 11, and uses multiple limiting members 12 and pushing members 13 to accurately position the first workpiece 200. The limiting members 12 are fixed to two adjacent sides of the loading area 111, providing stable boundary constraints; the pushing members 13 apply a pushing force to the first workpiece 200 on the other two adjacent sides, accurately pushing the first workpiece 200 to the limiting members 12. This achieves high-precision positioning, ensuring that the first workpiece 200 remains in the correct position during the pressing process, thereby improving the quality and consistency of the pressing.

[0043] In this embodiment, a clearance portion 112 may be provided on the positioning seat 11 at a position opposite to the pressing mechanism 20 for mounting the heating mechanism 30 or the detection mechanism.

[0044] In some embodiments, see Figure 1 and Figure 3 Multiple pushing members 13 are adjustablely connected to the positioning seat 11 in the direction toward the corresponding limiting member 12, so that the pushing member 13 can move closer to or further away from the corresponding limiting member 12. The limiting member 12 and the positioning seat 11 can be connected by a structure such as bolts. The positioning seat 11 can be provided with multiple bolt holes spaced apart. The limiting member 12 can be installed in different bolt holes by bolts, thereby completing the adjustment of the pushing member 13.

[0045] When changing to a different size and specification of the first workpiece 200, operators do not need to perform complex equipment disassembly and reinstallation. They can quickly complete the equipment debugging by simply adjusting the position of the pusher 13. This not only reduces production downtime caused by equipment debugging, but also lowers labor costs and the risk of potential equipment damage during the debugging process, improves production efficiency, and enhances the company's ability to meet diverse production needs.

[0046] In some embodiments, see Figure 1 and Figure 3 The positioning mechanism 10 also includes multiple adsorption elements 14, which are all disposed on the positioning seat 11 and located within the material loading area 111. The multiple adsorption elements 14 are used to adsorb the first workpiece 200. The adsorption element 14 can be a suction nozzle. The adsorption element 14 is connected to an external air extraction device (not shown). The external air extraction device can adsorb the first workpiece 200 through the adsorption element 14, thereby positioning the first workpiece 200 in the vertical direction.

[0047] During the pressing process, the first workpiece 200 may shift in position due to external forces, such as impact forces during pressing or equipment vibrations. The adsorption member 14, by generating an adsorption force, fixes the first workpiece 200 within the material loading area 111 of the positioning seat 11, effectively preventing displacement of the workpiece during pressing and ensuring the stability and reliability of the pressing process. The coordinated operation of the adsorption member 14, the pushing member 13, and the limiting member 12 enables more precise positioning of the first workpiece 200 in the predetermined position. The adsorption force ensures the stability of the first workpiece 200 during the pushing process, avoiding positioning deviations caused by uneven surfaces of the first workpiece 200 or uneven pushing forces, thereby further improving positioning accuracy.

[0048] The working process of the pressing device 100 provided in this embodiment is roughly as follows:

[0049] Before pressing, the heating mechanism 30 is removed from the positioning mechanism 10, and then the force gauge 41 is installed in the position corresponding to the pressing mechanism 20. During testing, the second detection block 43 is first placed on the force gauge 41, and the second detection block 43 is aligned with the fixed pressing member 231. At this time, the height of the second detection block 43 is consistent with the height of the second workpiece 300 to be pressed by the fixed pressing member 231. The pressing drive member 211 drives the fixed pressing member 231 to abut against the second detection block 43, and the pressure generated by the fixed pressing member 231 can be detected. Then, the first detection block 42 and the second detection block 43 are placed on the force gauge 41 at the same time, and the first detection block 42 is aligned with the elastic pressing member 221, and the second detection block 43 is aligned with the fixed pressing member 231. The pressing drive 211 drives the elastic pressing component 221 and the fixed pressing component 231 to simultaneously abut against the corresponding first detection block 42 and second detection block 43, thereby detecting the pressure of the elastic pressing component 221.

[0050] Then, the force measuring mechanism 40 is removed and the heating mechanism 30 is installed. The first workpiece 200 is placed in the loading area 111 of the positioning seat 11 of the positioning mechanism 10. The first workpiece 200 is bounded by multiple limiting members 12, and the first workpiece 200 is pushed to the limiting members 12 by multiple pushing members 13 to achieve precise positioning. Finally, the first workpiece 200 is further adsorbed by the adsorption member 14 to ensure that the first workpiece 200 is stably fixed on the positioning seat 11.

[0051] During pressing, the pressing drive 211 drives the connecting member 212 to move towards the second workpiece 300. The connecting member 212 drives the elastic pressing component 22 and the fixed pressing component 23 to move towards the corresponding second workpiece 300, until the elastic pressing component 22 and the fixed pressing component 23 press the corresponding second workpiece 300. After a preset pressing time, the pressing drive 211 drives the elastic pressing component 22 and the fixed pressing component 23 away from the second workpiece 300.
