Abstract
Description
Technical Field
[0001] This application relates to the field of assembly and processing technology, specifically to an assembly device. Background Technology
[0002] In the assembly and processing of electronic products, it is often necessary to assemble multiple small parts onto larger components. Traditional assembly methods typically involve using jigs or pressing devices to assemble multiple small parts simultaneously. Specifically, the small parts are first mounted onto the jig or pressing device, and then pressed together. However, traditional jigs or pressing devices cannot adaptively adjust the pressure on each small part. Due to potential errors in the mounting position of the small parts, or the uneven placement of the larger component, some small parts may fit correctly while others fail to assemble accurately, resulting in uneven assembly. Furthermore, if glue is needed between the small and large parts, uneven assembly can also lead to glue overflow and other problems. Utility Model Content
[0003] In view of the above, it is necessary to propose an assembly device that can simultaneously assemble multiple first workpieces onto a second workpiece, and can adaptively adjust the pressure on each first workpiece to improve the assembly effect.
[0004] This application provides an assembly device for assembling a first workpiece onto a second workpiece, comprising: a positioning mechanism including a positioning component configured to position the second workpiece; and a pressing mechanism including a pressing component and a plurality of pressing head assemblies. The pressing component includes a pressing drive and a heating component. The pressing drive is mounted above the positioning component, and the heating component is connected to the pressing drive. The heating component has a plurality of spaced-apart first receiving holes extending along a first direction. The plurality of pressing head assemblies are arranged one-to-one with the plurality of first receiving holes. Each pressing head assembly includes components sequentially arranged along a direction away from the positioning component. The first receiving hole includes a pressure head, an elastic element, and a stop element. The pressure head is slidably disposed in the first receiving hole. One end of the pressure head away from the elastic element extends out of the heating element and is configured to carry the first workpiece. The two ends of the elastic element abut against the pressure head and the stop element, respectively. The elastic element is configured to push the pressure head away from the stop element. The pressing drive element is configured to drive the heating element to move toward or away from the positioning component. The heating element is configured to heat the pressure head and drive the pressure head to move closer to or away from the positioning component. The pressure head is configured to assemble the first workpiece onto the second workpiece.
[0005] The aforementioned assembly equipment uses a positioning component in the positioning mechanism to position the second workpiece. The pressing mechanism includes a pressing drive and a heating component. The pressing drive can move the heating component closer to or away from the positioning component. The heating component has multiple first receiving holes, each containing a pressure head assembly.

During assembly, the positioning component positions the second workpiece, and then the first workpiece is mounted on the multiple pressure heads. The heating component heats the first workpiece, and the pressing drive moves the heating component closer to the second workpiece on the positioning component, thus assembling the multiple first workpieces onto the second workpiece. When the first workpiece abuts against the second workpiece, the elastic element can be compressed, adaptively adjusting the pressure of the corresponding pressure head on the first workpiece, ensuring each first workpiece is precisely assembled onto the second workpiece, effectively improving the assembly result.

[0024] Please see Figure 1 , Figure 2 and Figure 3 This application provides an assembly device 100 for assembling a first workpiece 200 onto a second workpiece 300. The first workpiece 200 can be a small part, such as a cap-shaped or columnar structure, while the second workpiece 300 can be a large part. The main body of the second workpiece 300 is generally a plate-like structure, and the second workpiece 300 can be provided with multiple assembly slots 301 to accommodate the first workpiece 200. In this embodiment, adhesive can also be applied between the first workpiece 200 and the second workpiece 300 to improve the stability of the assembly of the first workpiece 200 onto the second workpiece 300. The assembly device 100 includes a positioning mechanism 10 and a pressing mechanism 20.
[0025] Specifically, the positioning mechanism 10 includes a positioning component 11 configured to position the second workpiece 300. Thus, the second workpiece 300 can be positioned by the positioning component 11, improving stability during assembly.
[0026] The pressing mechanism 20 includes a pressing assembly 21 and multiple pressing head assemblies 22. The pressing assembly 21 includes a pressing drive 211 and a heating element 212. The pressing drive 211 is mounted above the positioning assembly 11. The heating element 212 is connected to the pressing drive 211. The heating element 212 has multiple spaced first receiving holes 2121 that all extend along a first direction. The multiple pressing head assemblies 22 are arranged one-to-one with the multiple first receiving holes 2121. Each pressing head assembly 22 includes a pressing head assemblies 2121 that extend along a first direction. The pressure head 221, the elastic element 222, and the stop element 223 are sequentially arranged in the first receiving hole 2121 away from the positioning component 11. The pressure head 221 is slidably disposed in the first receiving hole 2121. One end of the pressure head 221 away from the elastic element 222 extends out of the heating element 212 and is configured to carry the first workpiece 200. The two ends of the elastic element 222 abut against the pressure head 221 and the stop element 223 respectively. The elastic element 222 is configured to push the pressure head 221 away from the stop element 223.
[0027] The pressing drive 211 is configured to drive the heating element 212 to move toward or away from the positioning component 11. The heating element 212 is configured to heat the pressure head 221 and drive the pressure head 221 to move closer to or away from the positioning component 11. The pressure head 221 is configured to assemble the first workpiece 200 onto the second workpiece 300.
[0028] The pressing drive component 211 can be a cylinder, a telescopic motor, etc., and the heating component 212 can be a plate-like structure. In this embodiment, the heating component 212 is connected to a heating circuit, which heats the component 212. A temperature sensor can be installed on the heating component 212 to monitor its temperature in real time. When the temperature of the heating component 212 reaches the required level, the heating circuit stops heating the component 212. Of course, the heating component 212 can also be heated in other ways, which are not limited here. The number of first receiving holes 2121 in the heating component 212 can be two, three, four, etc., and the specific number and position are consistent with the number and position of the first workpiece 200 installed, which are not limited here. The number of pressing head assemblies 22 can be two, three, four, etc., and the number of pressing head assemblies 22 is consistent with the number of first receiving holes 2121. The pressure head 221 is generally cylindrical in shape and is slidably disposed in the first receiving hole 2121. The elastic element 222 can be a spring, etc., and the stop element 223 can be a block structure. During assembly, the first workpiece 200 is first installed on the end of the pressure head 221 that extends out of the first receiving hole 2121. Then, the heating element 212 heats up, thereby heating the pressure head 221. If glue needs to be applied, glue can be applied to the first workpiece 200 or to the assembly groove 301 of the second workpiece 300. Then, the pressing drive element 211 drives the heating element 212 to move closer to the second workpiece 300 of the positioning component 11. The pressure head 221 assembles the first workpiece 200 into the assembly groove 301 of the second workpiece 300. As the heating element 212 continues to move, the pressure head 221 can compress the elastic element 222, improving the consistency of assembly and preventing some of the first workpieces 200 from abutting against the second workpiece 300 first, thus preventing other first workpieces 200 from being mis-assembled. The heating element 212 can heat up the pressure head 221 and the first workpiece 200, thereby enhancing the stability of the connection between the first workpiece 200 and the second workpiece 300 after assembly.
[0029] The assembly equipment 100 provided in this application embodiment can position the second workpiece 300 through the positioning component 11 in the positioning mechanism 10. The pressing component 21 in the pressing mechanism 20 is provided with a pressing drive component 211 and a heating component 212. The pressing drive component 211 can drive the heating component 212 to move closer to or away from the positioning component 11. The heating component 212 has a plurality of first receiving holes 2121, and each first receiving hole 2121 is provided with a pressure head assembly 22. The pressure head assembly 22 includes a pressure head 221, an elastic component 222 and a stop component 223. The pressure head 221 is used to support the first workpiece 200. During assembly, the second workpiece 300 is positioned by the positioning component 11, and then the first workpiece 200 is installed on multiple pressure heads 221. The heating component 212 heats the first workpiece 200, and the pressing drive component 211 drives the heating component 212 to move closer to the second workpiece 300 on the positioning component 11, thereby assembling multiple first workpieces 200 onto the second workpiece 300. When the first workpiece 200 abuts against the second workpiece 300, the elastic component 222 can be compressed, thereby adaptively adjusting the pressure of the corresponding pressure head 221 on the first workpiece 200, so that each first workpiece 200 is accurately assembled onto the second workpiece 300, effectively improving the assembly effect. After the first workpiece 200 is heated by the heating component 212, the first workpiece 200 and the second workpiece 300 can be thermally pressed, further improving the stability of the first workpiece 200 assembled onto the second workpiece 300.
[0030] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The pressing assembly 21 also includes a heat insulation plate 213 and a plurality of first baffles 214. The heat insulation plate 213 is disposed on the side of the heating element 212 away from the positioning assembly 11. The heat insulation plate 213 has a plurality of second receiving holes 2131 that correspond one-to-one with the plurality of first receiving holes 2121. The plurality of first baffles 214 are all disposed on the side of the heat insulation plate 213 away from the heating element 212 and are disposed one-to-one with the plurality of second receiving holes 2131. Each first baffle 214 has a receiving cavity 2141 that communicates with the corresponding second receiving hole 2131. The heat insulation plate 213 is disposed on the side of the heating element 212 away from the positioning assembly 11, which can effectively isolate the heat generated by the heating element 212 and prevent the heat from being transferred to other components. This can avoid component damage or performance degradation caused by high temperature and extend the service life of the equipment. The number of second receiving holes 2131 can be two, three, four, etc., and the number and position of the second receiving holes 2131 correspond one-to-one with the number and position of the first receiving holes 2121. The number of first stops 214 can be two, three, four, etc., and the number and position of the first stops 214 correspond one-to-one with the number and position of the second receiving holes 2131.
[0031] Each pressure head assembly 22 includes a pressure sensor 224 disposed in a corresponding receiving cavity 2141. A stop member 223 is slidably disposed in a second receiving hole 2131 and abuts against the pressure sensor 224. The pressure sensor 224 is configured to detect the pressure on the stop member 223.
[0032] It is understood that the second receiving hole 2131 and the first receiving hole 2121 cooperate to receive the pressure head assembly 22. In this embodiment, the pressure head 221 is slidably disposed in the first receiving hole 2121, the stop member 223 is slidably disposed in the second receiving hole 2131, and the elastic member 222 is movably disposed in the first receiving hole 2121 and the second receiving hole 2131.
[0033] Each pressure head assembly 22 is equipped with a pressure sensor 224 to detect the pressure on the stop member 223. This design allows for real-time monitoring of the force on the pressure head 221 during assembly, ensuring uniformity and consistency in the pressing process. Through the pressure sensor 224, operators can adjust the pressing force based on actual pressure feedback, avoiding assembly defects caused by excessive or insufficient pressure. For example, excessive pressure may damage the workpiece, while insufficient pressure may result in a loose assembly. The use of the pressure sensor 224 effectively solves these problems, thereby improving assembly quality. It is understandable that after a period of operation, the elastic member 222 is prone to deformation, leading to insufficient pressure on the pressure head 221. When the pressure sensor 224 detects insufficient pressure during assembly, the operator can replace the elastic member 222.
[0034] In some embodiments, see Figure 1 , Figure 2 and Figure 3The pressing assembly 21 also includes a plurality of second stops 215. Each second stop 215 is disposed on the side of the heating element 212 opposite to the pressing drive element 211 and corresponds one-to-one with a plurality of first receiving holes 2121. Each second stop 215 has a limiting hole 2151 communicating with the corresponding first receiving hole 2121. The cross-sectional area of the limiting hole 2151 is smaller than the cross-sectional area of the first receiving hole 2121. The pressing head 221 includes a sliding part 2211 and a material loading part 2212 disposed opposite to each other. The sliding part 2211 is slidably disposed in the first receiving hole 2121, and the material loading part 2212 is slidably disposed through the corresponding limiting hole 2151. The second stops 215 are configured to abut against the sliding part 2211 to limit the pressing head 221. The number of second stops 215 can be two, three, four, etc., and the number and position of the second stops 215 correspond one-to-one with the number and position of the first receiving holes 2121. By setting the second stop 215, the pressure head 221 can be stopped, preventing the elastic element 222 from pushing the pressure head 221 out of the first receiving hole 2121. At the same time, the cooperation between the sliding part 2211 and the first receiving hole 2121, and the cooperation between the material loading part 2212 and the limiting hole 2151, can effectively reduce the shaking and displacement of the pressure head 221 during the movement, enhance the structural stability of the pressure head 221, and thus improve the reliability of the assembly process.
[0035] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The material-carrying part 2212 has a material-holding groove 2213 at one end away from the sliding part 2211. The material-holding groove 2213 is configured to hold the first workpiece 200. In this embodiment, the first workpiece 200 has a protrusion. By providing the material-holding groove 2213, the first workpiece 200 can be held. Through the fixing of the material-holding groove 2213, the first workpiece 200 is always kept in the correct position during the pressing process, thereby improving the assembly accuracy and consistency.
[0036] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The pressing assembly 21 also includes a limiting plate 216 and a plurality of limiting posts 217. The limiting plate 216 is connected to the pressing drive member 211 and disposed between the pressing drive member 211 and the heating member 212. The heating member 212 is connected to the side of the limiting plate 216 away from the pressing drive member 211 and is connected to the pressing drive member 211. The plurality of limiting posts 217 extend along the first direction and are disposed on the periphery of the positioning assembly 11. The limiting plate 216 and the plurality of limiting posts 217 are slidably connected. The plurality of limiting posts 217 are configured to limit the limiting plate 216.
[0037] The limiting posts 217 can be four, six, or more. In this embodiment, multiple limiting posts 217 are disposed around the periphery of the positioning assembly 11, and each limiting post 217 is slidably inserted into the limiting plate 216. Through the cooperation of the limiting plate 216 and the limiting posts 217, the heating element 212 connected to the limiting plate 216 can maintain linear motion when moving along the first direction, avoiding assembly errors caused by offset or shaking, and significantly improving assembly quality. In this embodiment, to enhance the stability of the limiting plate 216 during movement, a linear bearing can be provided on the limiting plate 216, and slidably connected to the limiting posts 217 via the linear bearing.
[0038] In some embodiments, see Figure 1 , Figure 3 and Figure 4 The positioning mechanism 10 also includes a pressing assembly 12, which includes a pressing drive 121 and a pressing plate 122. The pressing drive 121 is disposed on the side of the positioning assembly 11 along a second direction perpendicular to the first direction. The pressing plate 122 is connected to the pressing drive 121 and is mounted between the heating element 212 and the positioning assembly 11. The pressing plate 122 has a clearance hole 1221. The pressing drive 121 is configured to drive the pressing plate 122 to move along the first direction to press the second workpiece 300 on the positioning assembly 11. The clearance hole 1221 is configured to avoid the position where the second workpiece 300 is assembled with the first workpiece 200.
[0039] The pressure drive component 121 can be a cylinder, etc. In this embodiment, to improve the stability of the pressure plate 122 in holding the second workpiece 300, two pressure drive components 121 can be provided, respectively connected to both ends of the pressure plate 122, for synchronously driving the pressure plate 122 to rise or fall. The position of the clearance hole 1221 corresponds to the position of the first workpiece 200 to be assembled, and the number can be two, three, four, etc. It can be understood that by pressing the second workpiece 300 with the pressure plate 122 during assembly, the stability of the assembly process can be enhanced, thereby improving the assembly accuracy. After assembly, when the pressure head 221 is removed from the first workpiece 200, it is easy to drive the first workpiece 200 and the second workpiece 300 to be removed from the positioning component 11, affecting the separation of the pressure head 221 from the first workpiece 200. By pressing the second workpiece 300 with the pressure plate 122, it is convenient for the pressure head 221 to separate from the first workpiece 200.
[0040] In some embodiments, see Figure 1 , Figure 3 and Figure 4The positioning mechanism 10 also includes a transfer component 13, which includes a transfer drive 131 and a transfer plate 132. The transfer drive 131 is disposed below the pressing drive 211, and the transfer plate 132 is connected to the transfer drive 131. The positioning component 11 is disposed on the transfer plate 132. The transfer drive 131 is configured to drive the transfer plate 132 to move along a third direction perpendicular to the first and second directions, thereby causing the positioning component 11 and the second workpiece 300 to move into or out of the pressing drive 211 along the third direction.
[0041] The transfer drive 131 can be a linear module, etc. The transfer drive 131 drives the positioning component 11 to move in and out of the pressing drive 211 through the transfer plate 132, thereby facilitating the installation and removal of the second workpiece 300. During assembly, the transfer drive 131 moves the positioning component 11 out of the pressing drive 211 through the transfer plate 132. After the second workpiece 300 is placed on the positioning component 11, the transfer drive 131 transfers the positioning component 11 and the second workpiece 300 to the underside of the pressing drive 211 through the transfer plate 132. After assembly, the transfer drive 131 moves the positioning component 11 and the assembled first workpiece 200 and second workpiece 300 out of the underside of the pressing drive 211 through the transfer plate 132, which facilitates unloading.
[0042] In some embodiments, see Figure 1 , Figure 3 and Figure 4 The positioning component 11 includes a support plate 111, a plurality of fixed positioning members 112, a plurality of pushing driving members 113, and a plurality of movable positioning members 114. The support plate 111 is provided with a loading position 1111 configured to carry the second workpiece 300. The plurality of fixed positioning members 112 are disposed on the two adjacent sides of the loading position 1111. The plurality of pushing driving members 113 are connected to the support plate 111 and disposed close to the loading position 1111. The plurality of movable positioning members 114 are connected one-to-one with the plurality of pushing driving members 113, and the plurality of movable positioning members 114 are respectively opposite to the other two adjacent sides of the loading position 1111. The pushing driving members 113 are configured to drive the movable positioning members 114 connected to them to move toward the opposite fixed positioning members 112, thereby positioning the second workpiece 300.
[0043] The fixed positioning component 112 can be a block or plate structure, and the number of fixed positioning components 112 can be two, three, four, etc. The pushing drive component 113 can be a cylinder, etc., and there can be two pushing drive components 113. The movable positioning component 114 can be a block or plate structure, and the number of movable positioning components 114 can be two, three, four, etc. When positioning the second workpiece 300, the second workpiece 300 is placed on the loading position 1111 of the support plate 111. Each pushing drive component 113 drives the connected movable positioning component 114 to move towards the corresponding fixed positioning component 112, thereby pushing the second workpiece 300 against the fixed positioning component 112, thus completing the positioning of the second workpiece 300.
[0044] In some embodiments, see Figure 1 , Figure 3 and Figure 4 The support plate 111 has an adsorption hole 1112, which corresponds to the position where the second workpiece 300 is to be fitted with the first workpiece 200. The adsorption hole 1112 is configured to communicate with an external air extraction device (not shown). The external air extraction device draws air through the adsorption hole 1112, creating a negative pressure in the adsorption hole 1112, thereby adsorbing the second workpiece 300. During assembly, the second workpiece 300 needs to maintain a stable position to ensure that the first workpiece 200 can be accurately assembled into the designated position. The adsorption function can provide additional fixing force to prevent the second workpiece 300 from shifting due to vibration or external force during pressing, thereby improving the accuracy and reliability of assembly. In this embodiment, the adsorption hole 1112 can be located close to the position where the second workpiece 300 is to be fitted with the first workpiece 200 to further improve the accuracy of the first workpiece 200 being assembled with the second workpiece 300.
[0045] In some embodiments, see Figure 1 , Figure 3 and Figure 4 The positioning assembly 11 also includes a material sensor 115, which is connected to the support plate 111 and positioned at the loading position 1111. The material sensor 115 is configured to detect the second workpiece 300 at the loading position 1111. The material sensor 115 can be a proximity switch or other similar sensor. By placing the material sensor 115 at the loading position 1111, it can be confirmed before assembly whether the second workpiece 300 has been correctly placed on the loading position 1111. If the second workpiece 300 is not detected, the equipment can pause the assembly process to avoid assembly errors or equipment damage caused by the missing second workpiece 300.
[0046] The working process of the assembly equipment 100 provided in this embodiment is roughly as follows:
[0047] First, the second workpiece 300 is placed on the support plate 111 of the positioning assembly 11. The pushing drive 113 drives the movable positioning member 114 to push the second workpiece 300 toward the fixed positioning member 112, thereby positioning the second workpiece 300. Then, the external suction device adsorbs the second workpiece 300 through the suction hole 1112, increasing the stability of the second workpiece 300. The first workpiece 200 is installed in the material slot 2213 of the pressure head 221. The heating member 212 heats up, and then the heat is transferred to the first workpiece 200 through the pressure head 221, completing the heating process.
[0048] Then, the transfer drive 131 drives the transfer plate 132 to move along a third direction, thereby moving the positioning assembly 11 and the second workpiece 300 below the pressing drive 211 via the transfer plate 132. The pressing drive 121 drives the pressing plate 122 to move along a first direction, and the pressing plate 122 presses down on the second workpiece 300, further fixing the position of the second workpiece 300.
[0049] Next, the pressing drive 211 drives the limiting plate 216 to move, simultaneously driving the heat insulation plate 213 and the heating element 212 to move towards the positioning assembly 11. The heating element 212 drives the pressure head assembly 22 to approach the second workpiece 300, and the pressure head 221 of the pressure head assembly 22 presses the first workpiece 200 into the designated position of the second workpiece 300. The heat from the heating element 212 helps the first workpiece 200 and the second workpiece 300 to bond together, and the pressure sensor 224 detects the pressure on the stop member 223 in real time.
