[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0026] The present utility model provides a patch device, such as Figure 1As shown, the material adsorption device 1 and the material positioning device 2 arranged on one side of the material adsorption device 1 are included. The material positioning device 2 includes a loading platform 21 on which a target material 3 is placed and a material pressing component 22 arranged on the loading platform 21. After the material adsorption device 1 adsorbs the mounting material and places it on the target material 3, the material pressing component 22 presses the mounting material and the target material 3. Through the arrangement of this structure, the mounting material is adsorbed by the material adsorption device 1 and transferred to the loading platform 21, and when the mounting material is placed on the target material 3 pre-fixed on the loading platform 21, the mounting material and the target material 3 are pressed by the material pressing component 22, so that the mounting material can be closely attached to the target material 3 after being mounted, so as to solve the problem that the mounting material and the target material 3 are not in sufficient contact, and in the state where the material pressing component 22 is pressed, the entire loading platform 21 and the material pressing component 22 can be put into the furnace for baking and curing, and at this time, the mounting material is always closely attached to the target material 3, so as to solve the mounting displacement caused by the curing of glue and transportation after the mounting material is mounted, thereby realizing high-precision mounting of the mounting material. The patch equipment of the utility model can be applied to the mounting of electronic components on the surface of a circuit board in the manufacture of various electronic products, including but not limited to the mounting of optical devices.

[0027] Furthermore, combined with Figure 2 As shown, the material adsorption device 1 includes a first linear slide assembly 11, and a suction block assembly 12 arranged on the first linear slide assembly 11. The suction block assembly 12 includes a first suction block 121 connected to the first linear slide assembly 11, and a second suction block 122 adsorbed and connected to the first suction block 121. The second suction block 122 is connected to the vacuum generating device through the first suction block 121, so that after the second suction block 122 adsorbs the mounting material and moves onto the target material 3, the material pressing assembly 22 presses the second suction block 122 to press the mounting material and the target material 3. Through the setting of this structure, two independent suction blocks are used. In the process of the material adsorption device 1 adsorbing the mounting material, the vacuum generating device is first opened to allow the first suction block 121 to adsorb the second suction block 122, and the second suction block 122 adsorbs the mounting material. When the second suction block 122 absorbs the mounting material and transfers it to the loading platform 21, and the second suction block 122 is aligned with the pre-fixed target material 3, the material pressing component 22 is pressed on the second suction block 122. At this time, the vacuum generating device can be turned off to separate the second suction block 122 from the first suction block 121, and the material pressing component 22 continues to press down quickly to press the second suction block 122 and the mounting material toward the target material 3, and make the mounting material close to the target material 3. To ensure that when the material pressing component 22 is pressed down, the relative position of the mounting material and the target material 3 is always fixed, so that mounting displacement does not occur, so as to achieve high-precision mounting of the mounting material.

[0028] Furthermore, combined with Figure 3 and Figure 4 As shown, a first suction channel 1211 is provided in the first suction block 121, and the first suction block 121 is connected to a vacuum generating device through one end of the first suction channel 1211. A second suction channel 1221 corresponding to the other end of the first suction channel 1211 is provided in the second suction block 122. A third suction channel 1212 independent of the first suction channel 1211 is also provided in the first suction block 121, and an adsorption cavity 1222 connected to one end of the third adsorption channel 1212 is provided inside the second suction block 122, and the other end of the third adsorption channel 1212 is connected to the vacuum generating device, so that the second suction block 122 can adsorb the mounting material. Through the setting of this structure, the first adsorption channel 1211 is connected to the vacuum generating device, and the second adsorption channel 1221 is correspondingly connected to the first adsorption channel 1211, so that the first suction block 121 can stably and quickly adsorb the second suction block 122. At the same time, the third suction channel 1212 is used to connect the vacuum generating device, and the suction chamber 1222 is correspondingly connected to the third suction channel 1212, so that the second suction block 122 can stably and quickly adsorb the mounting material. Based on the independent first suction channel 1211 and third suction channel 1212 on the first suction block, the first suction block 121 adsorbs the second suction block 122, and the second suction block 122 adsorbs the mounting material independently, so as to adsorb the second suction block and the mounting material in turn, avoiding the position deviation between the second suction block 122 and the mounting material during the adsorption process, or other foreign matter being adsorbed on the second suction block 122.

[0029] Furthermore, the second suction block 122 is provided with a suction surface, and a plurality of suction holes 1223 connected to the suction cavity 1222 are provided on the suction surface, so that the second suction block 122 can suction the mounting material through the suction surface. Through the setting of this structure, the mounting material is suctioned by the suction surface to ensure that the second suction block 122 can horizontally suction and place the mounting material, so as to facilitate the subsequent mounting material to be accurately mounted on the target material 3. At the same time, the plurality of suction holes 1223 on the suction surface are used to increase the suction points of the mounting material on the suction surface, so as to ensure that the second suction block 122 can strongly suction and stably transfer the mounting material.

[0030] Further, look back Figure 1, the first linear slide assembly 11 is rotatably connected with a connecting plate 4, so that the first linear slide assembly 11 drives the connecting plate 4 to perform horizontal displacement. The first suction block 121 is connected to the first linear slide assembly 11 through the connecting plate 4. After the connecting plate 4 is flipped to the horizontal, the first suction block 121 is located on the side of the first linear slide assembly 11, so that the mounting material on the second suction block 122 corresponds to the target material 3 on the loading platform 21. Through the setting of this structure, the first linear slide assembly 11 is used to drive the connecting plate 4 to perform horizontal displacement in different directions, so as to adjust the first suction block 121 to move toward the loading platform 21, and adjust the mounting material on the second suction block 122 to correspond to the position of the pre-fixed target material 3 on the loading platform 21. At the same time, through the flippable connecting plate 4, the connecting plate 4 can be flipped open, so as to install the first suction block 121 on the connecting plate 4, and to adsorb the second suction block 122 and the mounting material in turn. After the second suction block 122 adsorbs the mounting material, the connecting plate 4 is flipped down to transfer the mounting material.

[0031] Furthermore, the material positioning device 2 also includes a second linear slide assembly 23, and the loading platform 21 is arranged on the second linear slide assembly 23, so that the second linear slide assembly 23 drives the loading platform 21 to move in the vertical direction. Through the arrangement of this structure, the second linear slide assembly 23 is used to drive the loading platform 21 to move in the vertical direction, so as to adjust the loading platform 21 to correspond to the suction block assembly 12, so that the mounting material adsorbed by the second suction block 122 can be directly transferred to the upper part of the pre-fixed target material 3 on the loading platform 21.

[0032] Preferably, the first linear slide assembly 11 and the second linear slide assembly 23 are conventional standard parts in the mechanical field. The first linear slide assembly 11 may include a base, a first linear slide arranged on the base, and a second linear slide arranged on the first linear slide. The first linear slide is arranged along the first horizontal direction, and is used to drive the second linear slide to move along the first horizontal direction; the second linear slide is arranged along the second horizontal direction, and the second horizontal direction is arranged at an angle to the first horizontal direction, and is used to drive the connecting plate 4 to move along the second horizontal direction. The second linear slide assembly 23 may include a base, a third linear slide arranged on the base, and the first linear slide is arranged along the vertical direction, and is used to drive the loading platform 21 to move along the vertical direction. Among them, the first linear slide, the second linear slide, and the third linear slide are respectively installed with a differential head. The differential head is also called a micrometer screw, a micrometer, etc. The differential head is made according to the principle of spiral amplification, that is, the micrometer screw of the differential head rotates one circle in the nut, and the micrometer screw moves forward or backward along the direction of the rotation axis by a pitch. Therefore, the minute distance moved along the axis direction can be represented by the reading on the circumferential surface of the nut. The first linear slide, the second linear slide, and the third linear slide are pushed by the micrometer screw of the differential head to achieve high-precision distance adjustment in thousandths.

[0033] Furthermore, if Figure 5 As shown, a material positioning groove 211 is provided on the loading platform 21, and a pressing frame 212 is provided on one side of the material positioning groove 211 on the loading platform 21. The material pressing assembly 22 includes an adjustment unit provided on the pressing frame 212, and a pressing block 221 provided on the adjustment unit. The pressing block 221 corresponds to the material positioning groove 211, so that after the target material 3 and the mounting material are both placed in the material positioning groove 211, the adjustment unit controls the pressing block 221 to press against the mounting material. Through the arrangement of this structure, the target material 3 is first placed in the material positioning groove 211 on the loading platform 21. When the second suction block 122 absorbs the mounting material and transfers it to the top of the material positioning groove 211 on the loading platform 21, and the second suction block 122 absorbs the mounting material and aligns it with the target material 3 pre-fixed in the material positioning groove 211, the second suction block 122 is pressed down by the adjustment unit to control the pressing block 221, and the second suction block 122 is separated from the first suction block 121 by turning off the vacuum generating device. At this time, the adjustment unit controls the pressing block 221 to continue to press down the second suction block 122, so as to press the second suction block 122 and the mounting material toward the target material 3 together, so as to realize the precise pressing of the mounting material and the target material 3 by the material pressing component 22, so as to improve the mounting accuracy of the mounting material.

[0034] Preferably, a plurality of material positioning grooves 211 and a plurality of material pressing components 22 are provided on the loading platform 21, and the plurality of material positioning grooves 211 and the plurality of material pressing components 22 correspond one to one, so as to facilitate the placement of multiple groups of placement materials and target materials 3 at one time.

[0035] Further, the adjustment unit includes a guide cylinder 222 connected to the pressing frame 212, a rotating rod 223 passing through the guide cylinder 222, and a limiting member 224 arranged on the rotating rod 223. A limiting groove 2221 is arranged on the guide cylinder 222, and the limiting groove 2221 is located at the top of the guide cylinder 222 and has an inlet, so that when the rotating rod 223 moves axially along the guide cylinder 222, the limiting member 224 moves into or out of the limiting groove 2221. The pressing block 221 is located below the guide cylinder 222, and the pressing block 221 is connected to the bottom end of the rotating rod 223. A first elastic member 225 is arranged between the pressing block 221 and the guide cylinder 222, so that after the limiting member 224 rotates to the inlet with the rotating rod 223, the first elastic member 225 pushes the pressing block 221 to press the mounting material in the material positioning groove 211. Through the setting of this structure, the automatic downward pressing method of rotation is adopted. Before the material adsorption device 1 adsorbs and transfers the mounting material, the rotary rod 223 is first lifted upward to move the limiter 224 out of the limiter groove 2221. At the same time, the pressing block 221 moves upward with the rotary rod 223 and compresses the first elastic member 225. Since the first elastic member 225 will push the pressing block 221 downward under the action of restoring deformation, it is necessary to rotate the rotary rod 223 to make the limiter 224 turn away from the placement entrance, so that the top of the guide cylinder 222 blocks the limiter 224 from moving downward, so that the pressing block 221 rises and is fixed. At this time, the pressing block 221 is away from the material positioning groove 211, and the target material 3 can be placed, as well as the transfer and placement of the mounting material. Similarly, when the second suction block 122 absorbs the mounting material and transfers it to the top of the material positioning groove 211 on the loading platform 21, and the second suction block 122 aligns the mounting material with the target material 3 pre-fixed in the material positioning groove 211, the rotary rod 223 is rotated to rotate the limiter 224 to the inlet, and the first elastic member 225 pushes the pressing block 221 downward under the action of restoring deformation, so that the pressing block 221 is quickly pressed down on the second suction block 122. After the second suction block 122 is separated from the first suction block 121, the first elastic member 225 continues to push the pressing block 221 downward quickly, so as to quickly press the second suction block 122 and the mounting material toward the target material 3, so as to realize that the material pressing assembly 22 can quickly and accurately press the mounting material and the target material 3, so as to improve the accuracy of mounting the mounting material.

[0036] Furthermore, combined with Figure 5 and Figure 6As shown, a pressing boss 5 is rotatably connected in the material positioning groove 211, and a second elastic member 6 is arranged on the pressing boss 5, so that the pressing boss 5 can press the target material 3 located on one side of the pressing boss 5 under the action of the second elastic member 6. Through the setting of this structure, using the rotatable pressing boss 5, it is only necessary to press the pressing boss 5 to rotate the pressing boss 5, at which time the pressing boss 5 rotates away from the pre-installed position of the target material 3 in the material positioning groove 211, and compresses the second elastic member 6, and at this time the target material 3 can be placed at the designated position in the material positioning groove 211. Similarly, when the pressing boss 5 is released, the pressing boss 5 will rotate in the opposite direction under the action of the second elastic member 6 restoring the deformation, and the target material will be pressed on one side of the target material, thereby achieving the fixation of the target material 3 and facilitating the taking and placing of the target material 3, so as to avoid the situation where the mounting material and the target material 3 are mounted and displaced when the mounting material is mounted, thereby achieving high-precision mounting of the mounting material.

[0037] Furthermore, a first placement groove 2111 and a second placement groove 2112 in which the target material 3 is pre-placed are provided in the material positioning groove 211. The pressing boss 5 is located in the first placement groove 2111, and the pressing boss 5 includes a positioning body 51 and a pressing body 52 provided on the positioning body 51. The pressing boss 5 is rotatably connected to the first placement groove 2111 through the positioning body 51. The second elastic member 6 connects the positioning body 51 and the inner groove wall of the first placement groove 2111, so that the positioning body 51, under the action of the second elastic member, presses the target material 3 in the second placement groove 2112 horizontally toward one side groove wall of the material positioning groove 211. Through the setting of this structure, the pressing boss 5 is divided into two parts, namely the positioning body 51 and the pressing body 52, and the pressing body 52 is used to facilitate the operator to press the positioning body 51. Preferably, the pressing body 52 is a protrusion formed on the positioning body 51. When the pressing body 52 is pressed, the positioning body 51 rotates toward the pressing side, and at this time, the positioning body 51 rotates away from the pre-installed position of the target material 3 in the material positioning groove 211, and can place the target material 3 in the second placement groove 2112. Similarly, when the pressing body 52 is released, the positioning body 51 will rotate in the opposite direction under the action of the second elastic member 6 restoring the deformation. Since the target material 3 is usually higher than the second placement groove 2112, the positioning body 51 can press the target material 3 in the second placement groove 2112 horizontally toward the groove wall of one side of the material positioning groove 211, so as to press and fix the target material 3.

[0038] Preferably, the first elastic member 225 and the second elastic member 6 can be conventional elastic parts such as springs.
