Description

Technical Field

[0001] This utility model relates to the field of mouse chip processing technology, specifically a tooling fixture for mouse chip processing. Background Technology

[0002] In the modern electronics manufacturing industry, the mouse, as an important computer peripheral device, relies heavily on the precision of its core control chip for its performance and lifespan. With the miniaturization of consumer electronics, mouse chips are shrinking in size, leading to increasingly higher precision requirements. This places higher demands on positioning and clamping technologies during chip manufacturing.

[0003] According to CN221247261U, a fixture for installing a mouse chip is disclosed. This technology discloses a technical solution including "a support box, a metal spring embedded in the center of the top surface of the support box, a small vibration motor installed at the bottom of the metal spring, limit plates welded to the top two sides of the support box, a screw installed inside the lower part of the limit plate, a bearing connected to the end of the screw, a clamping plate installed outside the bearing, and a slider connected to the bottom of the clamping plate, and grooves opened on the front and rear sides of the top of the support box". It has the technical effect of "clamping the mouse motherboard with the fixture, and then soldering the mouse chip. The small vibration motor drives the metal spring to vibrate slightly at high frequency, which can drive the mouse motherboard to vibrate slightly at high frequency, so that the solder paste distributed between the mouse chip pins and the mouse motherboard can vibrate fully, thereby completely wrapping the mouse chip pins and making the mouse chip soldering and installation more stable".

[0004] When existing chip fixtures need to clamp and fix multiple chips at the same time, the lack of an effective mechanical linkage system means that the movements of each clamping point cannot be kept synchronized and coordinated. This results in differences in the clamping force borne by different chips. Some chips may be deformed or damaged due to excessive clamping force, while other chips may be displaced during processing due to insufficient clamping force. This uneven clamping phenomenon directly affects the processing accuracy of chips and product consistency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a tooling fixture for mouse chip processing, which enables synchronous and precise clamping at multiple stations, ensures consistency of action at each clamping point, and guarantees uniform clamping force. It is particularly suitable for the batch processing needs of high-precision mouse chips.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tooling fixture for processing mouse chips, comprising a base, wherein a tooling mechanism is provided on the base for clamping and positioning the chip, the tooling mechanism comprising:

[0007] The adjustment assembly includes side seats fixed to the left and right ends of the top of the base. A balance bar is fixed between the two side seats. A first slide, a second slide, a third slide, and a fourth slide are slidably mounted on the balance bar from left to right. Two left short connecting brackets are pivotally connected to the top of the first slide. Two left long connecting brackets are pivotally connected to the top of the second slide and are pivotally connected to the left short connecting brackets. Two right long connecting brackets are pivotally connected to the top of the third slide and are pivotally connected to the left long connecting bracket. Two right short connecting brackets are pivotally connected to the top of the fourth slide and are pivotally connected to the right long connecting bracket. A cam is rotatably mounted at the upper end of the pivot point between the left and right long connecting brackets. A mounting plate is fixed between the tops of the two side seats. A limit bracket is fixed in the middle of the bottom of the mounting plate, and the cam is located inside the limit bracket. A bracket is fixed to the upper end of the first slide, the second slide, the third slide, and the fourth slide.

[0008] A clamping assembly is mounted on the adjustment assembly and is used for positioning and clamping the chip.

[0009] Preferably, the clamping assembly includes a left clamping plate installed on the top left side of the bracket, a right clamping plate installed on the top right side of the bracket, and clamps fixed on both sides of the top of the left clamping plate and both sides of the top of the right clamping plate.

[0010] Preferably, the clamping assembly further includes an outward protrusion fixed to the right end of the left clamping plate, an inward concave portion opened at the left end of the right clamping plate, a protrusion fixed to the right end of the outward protrusion, and a groove opened inside the inward concave portion.

[0011] Preferably, the clamp assembly further includes a notch formed at the corner of the inner wall of the clamp.

[0012] Preferably, the clamping assembly further includes mounting holes on both sides of the left clamping plate and both sides of the right clamping plate.

[0014] Beneficial effects

[0015] This utility model provides a tooling fixture for processing mouse chips. Compared with the prior art, it has the following advantages:

[0016] 1. When the fourth slide moves to the left, the third slide moves synchronously to the left through the linkage of the right short connecting frame and the right long connecting frame; at the same time, the right long connecting frame drives the second slide to move to the right in the opposite direction through the left long connecting frame, and the left long connecting frame drives the first slide to move synchronously to the right through the left short connecting frame; this allows the four-slide linkage mechanism to work with the limit frame to guide and limit the cam, ensuring that the clamping components on each slide can move precisely and synchronously; it realizes synchronous and precise clamping at multiple stations, ensuring the consistency of the action of each clamping point and ensuring uniform clamping force, which is particularly suitable for the batch processing needs of high-precision mouse chips, and significantly improves production efficiency while ensuring processing quality.

[0017] 2. The chip is placed on the protrusion and positioned by the bumps. Before the chucks perform the clamping action, the bumps first contact the edge of the chip to achieve pre-positioning, ensuring that the chip is in a precise processing position. When the left and right clamps move towards each other, the four chucks act synchronously on the chip on the protrusion, forming a clamping force that is evenly distributed at four points.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a tooling fixture for processing mouse chips, including a base 1, on which a tooling mechanism 2 is provided for clamping and positioning the chip, the tooling mechanism 2 including:

[0025] Adjustment assembly 21 includes side seats 211 fixed to the left and right ends of the top of base 1. A balance bar 212 is fixed between the two side seats 211. A first slide block 213, a second slide block 214, a third slide block 215, and a fourth slide block 216 are slidably mounted on the balance bar 212 from left to right. Two left short connecting brackets 217 are pivotally connected to the top of the first slide block 213. Two left long connecting brackets 218 are pivotally connected to the top of the second slide block 214 and are pivotally connected to the left short connecting brackets 217. Two right long connecting brackets 219 are pivotally connected to the top of the third slide block 215 and are pivotally connected to the left long connecting brackets. 218 is pivotally connected, and the top of the fourth slide 216 is pivotally connected to two right short connecting frames 2110 and the right long connecting frame 219. The upper end of the pivot point between the left long connecting frame 218 and the right long connecting frame 219 is rotatably mounted with a cam 2111. The top of the two side seats 211 is fixed between the tops of the two side seats 211. The bottom middle of the mounting plate 2112 is fixed with a limit frame 2113, and the cam 2111 is located inside the limit frame 2113. The upper ends of the first slide 213, the second slide 214, the third slide 215 and the fourth slide 216 are all fixed with brackets 2116.

[0026] The clamping assembly 22 is disposed on the adjusting assembly 21 and is used for positioning and clamping the chip.

[0027] In this implementation scheme, when the fourth slide 216 moves to the left, the third slide 215 moves to the left synchronously through the linkage of the right short connecting frame 2110 and the right long connecting frame 219. At the same time, the right long connecting frame 219 drives the second slide 214 to move to the right in the opposite direction through the left long connecting frame 218, and the left long connecting frame 218 drives the first slide 213 to move to the right synchronously through the left short connecting frame 217. This allows the four-slide linkage mechanism to cooperate with the limiting frame 2113 to guide and limit the cam 2111, ensuring that the clamping components 22 on each slide can move precisely and synchronously. This achieves synchronous and precise clamping at multiple workstations, ensuring the consistency of the action of each clamping point and ensuring uniform clamping force. It is particularly suitable for the batch processing requirements of high-precision mouse chips, significantly improving production efficiency while ensuring processing quality.

[0028] Specifically, the clamp assembly 22 includes a left clamp 221 installed on the top left side of the bracket 2116, a right clamp 222 installed on the top right side of the bracket 2116, and clamps 223 fixed on both sides of the top of the left clamp 221 and the top of the right clamp 222.

[0029] In this embodiment, when the left clamping plate 221 and the right clamping plate 222 move toward each other, the four clamps 223 act synchronously on the chip on the protrusion 224 to form a clamping force that is evenly distributed at four points.

[0030] Specifically, the clamp assembly 22 also includes an outward protrusion 224 fixed to the right end of the left clamping plate 221, an inward concave portion 225 opened at the left end of the right clamping plate 222, a protrusion 226 fixed at the right end of the outward protrusion 224, and a groove 227 opened inside the inward concave portion 225.

[0031] In this embodiment, the chip is placed on the protrusion 224 and positioned by the bump 226. Before the chuck 223 performs the clamping action, the bump 226 first contacts the edge of the chip to achieve pre-positioning, ensuring that the chip is in a precise processing position.

[0032] Specifically, the clamp assembly 22 also includes a notch 228 formed at the corner of the inner wall of the chuck 223.

[0033] In this embodiment, the notch 228 avoids mechanical damage to the chip corners caused by right-angle contact during clamping.

[0034] Specifically, the clamping assembly 22 also includes mounting holes 229 on both sides of the inside of the left clamping plate 221 and both sides of the inside of the right clamping plate 222.

[0035] In this embodiment, the left clamp 221 and the right clamp 222 can be fixed to the top of the bracket 2116 by bolts through the mounting holes 229, which facilitates quick replacement of the appropriate clamps according to different chip specifications.

[0036] Specifically, the adjustment assembly 21 also includes a cylinder 2114 installed on the right end of the mounting plate 2112. The output end of the cylinder 2114 is fixed with a connector 2115, and the connector 2115 is connected to the fourth slide block 216.

[0037] In this embodiment, the output end of the cylinder 2114 drives the connector 2115 to drive the fourth slide block 216 to slide horizontally along the balance bar 212.

[0038] The working principle and usage process of this utility model are as follows: First, the chip is placed on the outer protrusion 224 and positioned by the protrusion 226; before the chuck 223 performs the clamping action, the protrusion 226 first contacts the edge of the chip to achieve pre-positioning, ensuring that the chip is in a precise processing position;

[0039] Then, the output end of cylinder 2114 drives connector 2115 to drive the fourth slide 216 to slide horizontally along balance bar 212; when the fourth slide 216 moves to the left, the linkage between the right short connecting frame 2110 and the right long connecting frame 219 drives the third slide 215 to move to the left in sync; at the same time, the right long connecting frame 219 drives the second slide 214 to move to the right in the opposite direction through the left long connecting frame 218, and the left long connecting frame 218 drives the first slide 213 to move to the right in sync through the left short connecting frame 217; so that the four slide linkage mechanism, together with the limit frame 2113, guides and limits the cam 2111, ensuring that the clamping components 22 on each slide can move precisely and synchronously.

[0040] Meanwhile, when the left clamping plate 221 and the right clamping plate 222 move toward each other, the four clamps 223 act synchronously on the chip on the protrusion 224, forming a clamping force evenly distributed at four points; this achieves synchronous and precise clamping at multiple stations, ensuring the consistency of action at each clamping point and guaranteeing uniform clamping force. It is particularly suitable for the batch processing needs of high-precision mouse chips, significantly improving production efficiency while ensuring processing quality.
