[0002] During the chip mounting process of a module, generally, a gripper is used to move a carrier plate loaded with workpieces to be chip-mounted onto a vacuum platform, and then the vacuum platform adsorbs the workpieces to be chip-mounted and the gripper presses against the carrier plate to fix the relative position between the carrier plate and the workpieces to be chip-mounted thereon. However, during chip mounting, the chip mounting head of the chip mounter presses down on the carrier plate with a certain pressure and performs a lateral pushing action thereon. This lateral pushing action will cause the carrier plate to move slightly, resulting in a large gap between the mounted workpieces and a low chip mounting yield. Summary of the Utility Model

[0033] See Figures 1 to 5The embodiment of the present application provides a fixing device, which includes: a working platform 100, which is provided with a fixing position for placing a carrier 1; a driving component 200, which is arranged on the working platform 100; an adjusting component 300, which is arranged at the output end of the driving component 200; and a pressing piece 400, which is connected to the driving component 200 through the adjusting component 300 and is located above the fixing position. The driving component 200 drives the pressing piece 400 to approach or move away from the fixing position to tighten or loosen the carrier 1, and the adjusting component 300 is used to adjust the flatness of the pressing piece 400.

[0034] In this embodiment, by adding a driving component 200, an adjusting component 300 and a pressing piece 400 connected to the output end of the driving component 200, a pressure can be provided to the carrier 1 to press against the working platform 100, so as to prevent the gap between the carrier 1 and the workpiece to be processed from being greatly different from the predetermined processing gap and the low product processing yield rate due to the slight movement of the carrier 1 by the original lateral pushing action of the patch equipment during the patch operation, thereby effectively improving the position stability of the carrier 1, improving the gap accuracy between the carrier 1 and the workpiece to be processed, and improving the processing yield rate of the workpiece to be processed. At the same time, by adjusting the flatness of the pressing piece 400 pressed on the carrier 1 by adjusting the adjusting component 300, it can also effectively avoid the problem that the carrier 1 will be slightly deformed and slightly tilted upward when the patch equipment is pressed down, so that the carrier 1 is unevenly stressed and the patch effect of the workpiece to be processed on the carrier 1 is poor, thereby improving the force uniformity of the carrier 1 when the patch equipment is pressed down, and effectively improving the patch yield rate of the product.

[0035] Specifically, the fixing device is configured as a combined component including at least the working platform 100, the driving component 200, and the pressing component 400. The working platform 100 can be two tracks arranged at intervals and provided with card slots. The two card slots are respectively arranged on the opposite inner sides of the two tracks for plugging the opposite sides of the carrier plate 1. The two tracks extend along a preset direction to move the carrier plate 1 along the preset direction, facilitating the next process. The working platform 100 provided in this example provides at least a supporting force for the carrier plate 1 and defines the position of the carrier plate 1 at least in the direction perpendicular to the moving direction of the carrier plate 1, improving the position stability and reliability of the carrier plate 1 and the working platform 100 in at least three degrees of freedom. The driving component 200 can be a driving cylinder, which can be arranged on the working platform 100 and above the carrier plate 1, used to provide a driving force for the pressing component 400 to approach or move away from the carrier plate 1, and provide a driving force for the pressing component 400 to press the carrier plate 1, so as to realize the limit of the top of the carrier plate 1 through the pressing component 400. The pressing component 400 can be a near-plate-shaped structure with a hollowed-out avoidance area, which can be connected to the output end of the driving component 200 by means of clamping, fastening with screws / bolts, etc. The bottom surface of the pressing component 400 can be approximately a plane, which is used to press against the top surface of the carrier plate 1 to realize the pressing of the top of the carrier plate 1, at least realizing the limitation of the degree of freedom above the carrier plate 1, and further improving the position stability and reliability of the carrier plate 1 and the working platform 100. It should be explained that the hollowed-out avoidance area provided on the pressing component 400 can avoid the workpieces to be processed placed on the carrier plate 1 to prevent the pressing component 400 from scratching or damaging the workpieces to be processed. In this way, the position between the workpieces to be processed and the carrier plate 1 can be limited, the processing gap accuracy between the two can be improved, and the processing accuracy and processing yield can be improved. At the same time, the workpieces to be processed can be protected, and the yield of the workpieces to be processed can be improved.

[0036] In one example, the chip mounter can be provided with two attaching heads, which are oppositely arranged on the opposite sides of the carrier plate 1. At this time, the fixing device can be provided with one working platform 100, two driving components 200, and two pressing components 400. One pressing component 400 is correspondingly connected to the output end of one driving component 200 to form a pressing group. The two pressing groups are oppositely arranged, and one pressing group corresponds to one attaching head to press and heat-cure the workpieces to be processed on the carrier plate 1 corresponding to the attaching head, improving the chip mounting efficiency and chip mounting effect.

[0037] It can be explained that the fixing device provided in this application is not limited to the chip mounter, and it is also applicable to any device with requirements for the processing gap accuracy between the carrier plate 1 and the workpieces to be processed, such as coding devices, dispensing devices, etc.

[0038] Such as Figures 2 to 4, in a possible implementation, the pressing member 400 includes a connecting portion 410 and a pressing portion 420. The pressing portion 420 is connected to the driving assembly 200 through the connecting portion 410, and the pressing portion 420 is located above the fixed position.

[0039] In this embodiment, the specific configuration of the pressing member 400 is optimized. Specifically, the pressing member 400 is configured as a composite structure including at least a connecting portion 410 and a pressing portion 420. The connecting portion 410 can be a solid plate-like structure with a near-square through-hole provided thereon, and the through-hole can avoid the fixing screw on the output end of the driving assembly 200. The pressing portion 420 can be a frame structure with a hollowed-out avoidance area, which is correspondingly arranged above the carrier plate 1; the hollowed-out avoidance area on the pressing portion 420 can not only avoid the workpiece to be processed provided on the carrier plate 1, but also avoid the attaching head of the chip mounter; the periphery of the pressing portion 420 can be pressed against the top surface of the carrier plate 1 to provide a downward pressure to the carrier plate 1 towards the working platform 100, so that the carrier plate 1 is in good fit with the vacuum platform below, and the adsorbing member 500 on the vacuum platform can firmly adsorb the workpiece to be processed, fix the position between the carrier plate 1 and the workpiece to be processed, ensure that the gap between the two is the preset processing gap, and improve the processing effect; at this time, the attaching head can pass through the hollowed-out avoidance area and act on the workpiece to be processed in this area to realize the chip mounting operation on the workpiece to be processed.

[0040] In a possible implementation, the pressing portion 420 includes a front beam 421 and two connecting beams 422. The two ends of the front beam 421 are respectively connected to the corresponding connecting portion 410 through the two connecting beams 422.

[0041] In this embodiment, the specific configuration of the pressing part 420 is optimized. Specifically, the pressing part 420 is configured as a composite structure including at least a front beam 421 and two connecting beams 422. The front beam 421 can be a connecting rod with convex teeth, and a plurality of convex teeth can be provided thereon. The plurality of convex teeth are distributed at intervals between the two connecting beams 422. The convex teeth face the carrier plate 1 and are used to press against the top surface of the carrier plate 1. There is a height difference between the bottom surface of the convex teeth and the bottom surface of the connecting rod. This height difference can make up for the height of the bearing platform on the carrier plate 1 for placing the workpiece to be processed. When the pressing member 400 presses down, the top surface of the workpiece to be processed can be approximately on the same horizontal plane as the top surface of the connecting rod, avoiding scratching the workpiece to be processed during the rising of the pressing member 400 and the movement of the carrier plate 1, and facilitating the subsequent processing by the chip mounter. The connecting beam 422 can be a gun-shaped plate structure. One end thereof close to the connecting part 410 is thicker to enhance the connection tightness and reliability between the connecting beam 422 and the connecting part 410; the end close to the front beam 421 is thinner to reduce the overall weight on the front side of the pressing member 400 and avoid damaging the carrier plate 1; at the same time, the thinner front end of the connecting beam 422 can also avoid the attaching head of the chip mounter in the height direction Z of the pressing member 400, preventing the attaching head from hitting the connecting beam 422 and realizing mechanical protection for the attaching head.

[0042] In a possible implementation manner, the connecting beam 422 is inclined, and in the height direction Z of the pressing member 400, the height of the connecting beam 422 closer to the front beam 421 is smaller. With this setting, on the one hand, the overall weight of the pressing member 400 can be reduced, the moving difficulty of the pressing member 400 can be decreased, and the operation can be facilitated; on the other hand, the attaching head of the chip mounter can be avoided at the front end of the pressing member 400, realizing mechanical protection for the chip mounter. Moreover, the inclined connecting beam 422 can also improve the external aesthetics of the pressing part 420. The connecting beam 422 provided in this example is more convenient to process and has a low production cost.

[0043] In a possible implementation manner, a first avoidance notch 4221 is provided on the side of the connecting beam 422 close to the front beam 421, and the first avoidance notch 4221 is located on the side of the connecting beam 422 away from the working platform 100. With this setting, an avoidance space in the height direction Z can be formed on the front side of the connecting beam 422, further reducing the risk of the attaching head hitting the connecting beam 422 and improving the mechanical protection for the chip mounter. The cooperation between the connecting beam 422 provided in this example and the chip mounter is safer.

[0044] As Figures 1 to 5 , in a possible implementation manner, the pressing part 420 further includes a partition beam 423. The partition beam 423 is arranged at intervals between the two connecting beams 422, and both ends of the partition beam 423 are respectively connected between the front beam 421 and the connecting part 410.

[0045] In this embodiment, the specific configuration of the pressing part 420 is further optimized. Specifically, the pressing part 420 is configured as a composite structure including at least a front beam 421, two connecting beams 422 and a partition beam 423. The partition beam 423 can be a gun-shaped rod with one end thick and the other end thin, and its thick end is connected to the connecting part 410, and its thin end is connected to the front beam 421. In this way, the connection tightness between the partition beam 423 and the connecting part 410 can be enhanced, and an avoidance space in the height direction Z can be formed at the front beam 421, so as to avoid the attachment head of the patch equipment and improve the operation safety. In addition, by adding the partition beam 423, the contact area between the pressing part 420 and the carrier 1 can be increased, and the pressing stability can be improved. For example but not limited to, two partition beams 423 are provided, and the two partition beams 423 are spaced apart between the two connecting beams 422 to further enhance the pressing effect of the pressing member 400 on the carrier 1, improve the position stability between the carrier 1 and the workpiece to be processed, and improve the processing accuracy.

[0046] like Figure 2 and Figure 4 In a possible implementation manner, the pressing piece 400 further includes a second avoidance notch 430 , and the second avoidance notch 430 is disposed on a side of the connecting portion 410 facing the working platform 100 .

[0047] In this embodiment, the specific configuration of the pressing piece 400 is further optimized. Specifically, the pressing piece 400 is configured as a composite structure including at least a connecting portion 410, a pressing portion 420, and a second avoidance notch 430. The second avoidance notch 430 is arranged below the connecting portion 410, which can reduce the overall weight of the connecting portion 410, so as to transfer the center of gravity of the pressing piece 400 to the pressing portion 420, avoid the pressing piece 400 from tipping over and tilting toward the connecting portion 410, and improve the stability of the pressing piece 400.

[0048] like Figure 1 and Figure 5 In a possible implementation, the driving assembly 200 includes a gantry 210, a connecting member 220 and a driving member 230. The gantry 210 is erected above the working platform 100. The connecting member 220 is movably disposed on the gantry 210 through the driving member 230 and is located above the second avoidance gap 430. The pressing member 400 is connected to the connecting member 220 through the adjusting assembly 300.

[0049] In this embodiment, the specific configuration of the driving component 200 is optimized. Specifically, the driving component 200 is configured as a combined component including at least a gantry 210, a connecting member 220, and a driving member 230. The gantry 210 can be configured as a combined component including at least two brackets and a crossbeam. The two brackets are respectively arranged on opposite sides of the working platform 100, and the crossbeam is erected on the tops of the two brackets and located above the working platform 100. The connecting member 220 can be a horizontally arranged plate-like structure, which is located below the crossbeam of the gantry 210. The two ends of the connecting member 220 can be respectively slidably connected to the two brackets of the gantry 210 through sliders to reduce the moving friction between the connecting member 220 and the gantry 210, facilitating the subsequent movement of the connecting member. At the same time, the connection stability and reliability of the connecting member 220 and the moving stability can also be improved through the two brackets. The driving member 230 can be a cylinder / motor and is located between the crossbeam and the connecting member 220. One end of the driving member 230 is fixedly arranged on the crossbeam of the gantry 210, and the output end is connected to the connecting frame 220. In this way, the driving member 230 can drive the connecting member 220 to approach or move away from the working platform 100 along the bracket, thereby driving the pressing member 400 connected to the connecting member 220 to approach or move away from the working platform 100 to press or release the carrier plate 1 placed on the working platform 100.

[0050] As Figures 2 to 5 , in a possible implementation manner, a connection hole 411 is provided on the connection part 410, a locking hole 201 corresponding to the connection hole 411 and adjustment holes 202 distributed on the periphery of the locking hole 201 are provided on the connecting member 220. The adjustment assembly 300 further includes a fixing member 310 and an adjusting member 320. The fixing member 310 is sequentially inserted into the locking hole 201 and the connection hole 411, and the adjusting member 320 is inserted into the adjustment hole 202 and abuts against the connection part 410 to adjust the conforming degree of the pressing part 420 and the carrier plate 1.

[0051] In this embodiment, the specific configuration of the adjusting component 300 is optimized. Specifically, connecting holes 411 are provided at intervals on the connecting portion 410 of the pressing component 400. At the same time, locking holes 201 and adjusting holes 202 corresponding to the connecting holes 411 are provided on the connecting member 220, and the adjusting component 300 is configured as a combined component including at least a fixing member 310 and an adjusting member 320. The fixing member 310 can be a component such as a screw / bolt / plug, etc., which can be sequentially inserted into the locking hole 201 and the connecting hole 411 to realize the firm connection between the pressing component 400 and the connecting member 220. The adjusting member 320 can be a component such as a screw / bolt / plug or a set screw, etc., which can be inserted into the locking hole 201 and abutted against the top of the connecting portion 410. In this way, the adjusting member 320 can be screwed to adjust the degree of fitting between the pressing portion 420 and the carrier plate 1 by controlling the insertion degree of the adjusting member 320 into the adjusting hole 202 and the abutting tightness between the adjusting member 320 and the top wall surface of the connecting portion 410. For example, when the front and rear sides of the pressing portion 420 are overly fitted with the carrier plate 1, or the left and right sides are overly fitted, the tightening degree of the adjusting members 320 on the front and rear sides with the locking holes 201 can be adjusted, or the tightening degree of the adjusting members 320 on the left and right sides with the locking holes 201 can be adjusted, so as to lock the connecting portion 410 and the connecting member 220 in this direction, lift the pressing portion 420 upward, reduce the abutting pressure of the pressing portion 420 on the carrier plate 1, and eliminate the excessive fitting between the pressing portion 420 and the carrier plate 1 in this direction; when the front and rear sides of the pressing portion 420 are not fitted enough with the carrier plate 1, or the left and right sides are overly fitted, the tightening degree of the adjusting members 320 on the front and rear sides with the locking holes 201 can be loosened, or the tightening degree of the adjusting members 320 on the left and right sides with the locking holes 201 can be loosened, so as to loosen the connecting portion 410 and the connecting member 220 in this direction, so that the pressing portion 420 presses against the carrier plate 1, and the self-weight of the pressing portion 420 is used to increase the pressing force on the carrier plate 1. The whole adjustment method is simple and convenient to operate.

[0052] For example but not limited to, there are four connecting holes 411, and the four connecting holes 411 are arranged at intervals along the direction of the two connecting beams 422; there are four locking holes 201, and one locking hole 201 corresponds to one connecting hole 411; there are four fixing members 310, and one fixing member 310 corresponds to one locking hole 201 and one connecting hole 411. There are 8 adjusting holes 202, one locking hole 201 corresponds to two adjusting holes 202, and the two adjusting holes 202 are respectively arranged on the opposite sides of the locking hole 201; there are 8 adjusting members 320, and one adjusting member 320 is arranged corresponding to one adjusting hole 202. In this way, the fitting property between different parts of the pressing portion 420 and the carrier plate 1 can be adjusted by adjusting the tightness between one or several of the adjusting members 320 and the corresponding adjusting holes 202, which is beneficial to improving the fitting accuracy between the pressing portion 420 and the carrier plate 1 and enhancing the overall stability of the carrier plate 1.

[0053] As Figure 5 , in a possible implementation, it further includes an adsorbing member 500. The adsorbing member 500 is correspondingly fixed at a fixed position on the working platform 100, and the adsorbing member 500 is used to adsorb the workpiece to be processed on the carrier plate 1.

[0054] In this embodiment, the specific configuration of the fixing device is further optimized. Specifically, the fixing device is configured as a combined component at least including the working platform 100, the driving component 200, the pressing component 400 and the adsorbing member 500. The adsorbing member 500 can be a vacuum adsorption platform, which is used to adsorb and fix the workpiece to be processed at a preset position on the carrier plate 1, so as to improve the relative position stability between the carrier plate 1 and the workpiece to be processed.

[0055] As Figure 6 shown, in a possible implementation, the pressing component 400 is further provided with positioning holes 412, the connecting member 220 is provided with alignment holes corresponding to the positioning holes 412, and the fixing device further includes positioning pins 600. The positioning pins 600 are inserted into the positioning holes 412. When the pressing component 400 is connected to the connecting member 220, the positioning pins 600 are inserted into the alignment holes. The fixing device provided in this example is convenient for alignment, has high assembly accuracy and high assembly efficiency.

[0056] For example but not limited to, there are two positioning holes 412, and the two positioning holes 412 are located in the middle of the four connecting holes 411; there are two alignment holes, and one alignment hole is correspondingly arranged with one positioning hole 412; there are two positioning pins 600, and one positioning pin 600 is correspondingly inserted into one positioning hole 412 and inserted into the corresponding alignment hole. In this way, the alignment accuracy between the pressing component 400 and the connecting member 220 is improved at least in terms of quantity, and the assembly efficiency is improved.

[0057] In addition, as Figures 1 to 5 , the embodiment of the present application also provides a chip mounter, including the fixing device described in any one of the above. The specific structure of the fixing device refers to the above embodiment.
