Description

Technical Field

[0001] This invention relates to the field of watch parts assembly technology, specifically to an assembly device for a watch battery and casing. Background Technology

[0002] With the rapid development of high-end industrial product processing technology at home and abroad and the increasingly fierce market competition, controlling product quality has become the common pursuit of all enterprises. Product quality has become the top priority in the product production process. For example, when assembling watch batteries into watch cases, with the miniaturization and integration of products, the requirements for battery assembly are getting higher and higher. Moreover, since batteries are explosive products, the space left for battery installation in watch cases is limited. This requires fast and efficient assembly.

[0003] Chinese patent discloses an assembly device for a watch battery and casing (publication number CN106002167A). This patented technology includes an installation platform, a six-axis robot, a battery loading mechanism, a loading and unloading conveyor line, an installation alignment vision system, and a pressure holding mechanism. The battery loading mechanism includes a battery platform and a battery loading cylinder; the loading and unloading conveyor line includes a casing platform and a conveying mechanism; the six-axis robot moves the battery into the casing on the casing platform using a suction cup; the installation alignment vision system includes an assembled CCD and its light source A for taking pictures to determine the position of the casing on the casing platform, and a microscope camera and its light source B for taking pictures to determine the relative position of the casing and the battery on the casing platform; the pressure holding mechanism includes a pressure holding head and a pressure holding linear module that drives the pressure holding head to maintain pressure after the battery and casing are attached and assembled. This invention enables rapid and efficient assembly of a watch battery into a watch case, ensuring the battery's relative position and secure fit. However, before installing the battery, the watch's main chip needs to be placed inside the case. Excessive pressure applied during battery installation can damage this chip. Existing assembly devices typically use electronic controllers to control the pressing pressure, which are more prone to failure than traditional mechanical structures, potentially leading to excessive pressure and damage to the chip. Therefore, this invention provides an assembly device for a watch battery and watch case to address these problems. Summary of the Invention

[0004] The purpose of this invention is to provide an assembly device for a watch battery and a watch case, in order to solve the problem mentioned in the background art that excessive force can be applied to the battery, resulting in damage to the main chip in the watch case.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An assembly device for a watch battery and casing includes an assembly platform. A placement mechanism is provided at the upper end of the assembly platform. The placement mechanism includes a storage rack and a movable placement plate. An assembly mechanism for placing materials from the storage rack onto the placement plate is installed inside the assembly platform. The assembly mechanism includes an assembly tube and a lifting tube that can move up and down inside the assembly tube. A limiting mechanism is provided between the lifting tube and the assembly tube. The limiting mechanism includes several push rings coaxially disposed inside the lifting tube. Each push ring has a push rod fixedly installed on its outer wall. Multiple push sleeves corresponding to the push rods are fixedly installed on the inner wall of the lifting tube, and the push rods are slidably disposed inside the push sleeves. A limiting spring is fixedly installed on the inner wall of the assembly tube corresponding to the push sleeve, and a stop block is fixed to the other end of each limiting spring.

[0006] As a further embodiment of the present invention, a longitudinal slide rail is fixedly installed on the upper end of the mounting platform, and the placement plate is slidably installed on the upper end of the longitudinal slide rail. Multiple battery blocks are placed in the storage rack. A discharge hopper is fixedly connected to the upper end of the mounting platform. A control rod is fixedly installed on the upper end of the mounting platform near the discharge hopper. A baffle is slidably installed on the upper end of the placement plate. A pressing plate that can press the watch case is slidably installed on the end of the placement plate away from the baffle.

[0007] As a further embodiment of the present invention, a transverse slide rail is fixedly installed above the mounting platform, a pneumatic telescopic rod is slidably installed on the side end of the transverse slide rail, a mounting frame is fixedly installed at the output end of the pneumatic telescopic rod, and an air suction pipe is fixedly installed inside the mounting frame.

[0008] As a further embodiment of the present invention, a rotating connecting pipe is rotatably mounted on the lower end of the suction pipe, and the mounting pipe is rotatably mounted on the lower end of the rotating connecting pipe, and the mounting pipe is fixedly connected to the mounting bracket.

[0009] As a further embodiment of the present invention, a fixing ring is fixedly installed at the lower end of the mounting tube, and the lifting tube is slidably installed inside the mounting tube. A mounting cover is fixedly installed at the lower end of the lifting tube, and a mounting ring is fixedly installed at the lower end of the mounting cover. A telescopic spring is fixedly installed between the mounting ring and the fixing ring, and an air suction hopper is fixedly installed at the lower end of the mounting ring.

[0010] As a further embodiment of the present invention, a fixing frame is fixedly installed at one end of the lifting tube near the inner wall of the pushing ring, and a limit rod is slidably installed at one end of the fixing frame near the pushing ring.

[0011] As a further embodiment of the present invention, a push plate is fixedly installed at the lower end of the limiting rod, and a retaining ring is fixedly installed at the upper end of the limiting rod.

[0012] As a further embodiment of the present invention, a semi-through plate is fixedly installed at the upper end of the lifting pipe, a threaded ring is threadedly installed on the inner wall of the mounting pipe near the semi-through plate, a sliding frame is fixedly installed on the outside of the threaded ring, and the sliding frame is slidably installed on the inner wall of the rotating connecting pipe, a sliding plate is slidably installed on the inner wall of the sliding frame, and the gap of the sliding plate matches the gap of the semi-through plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. When using this invention, when the push plate presses the battery block, the limit rod rises and pushes the push ring to move, thereby causing the push rod to push the stop block out of the push sleeve. The stop ring set at the upper end of the limit rod pushes the push ring to move upward, causing the lifting tube to slide upward in the inner wall of the mounting tube. When the lifting tube retracts, the mounting ring and the fixing ring squeeze the telescopic spring, causing the mounting ring to press the battery block, thereby fixing the battery block in the watch case. As the distance between the mounting ring and the fixing ring pressing the battery gradually decreases, the pushing force provided by the telescopic spring is greater, and the distance the lifting tube moves in the inner wall of the mounting tube is longer. When the semi-through plate installed at the upper end of the lifting tube contacts the sliding plate slidably installed on the sliding frame, the semi-through plate and the sliding plate seal the lifting tube. The negative pressure generated in the suction pipe drives the lifting tube to move upward. After the semi-through plate and the sliding plate seal the lifting tube, the suction bucket no longer sucks up the battery block, thereby keeping the pressure of pressing the battery block within a reasonable range during the installation process.

[0014] 2. When using this invention, rotating the rotating connecting pipe causes the threaded ring at the upper end of the sliding frame to rotate, causing the sliding frame to move up or down. This increases or decreases the distance between the sliding frame and the semi-through plate installed at the upper end of the lifting pipe, and increases or decreases the distance between the mounting ring and the fixed ring pressing the telescopic spring. This makes it more convenient to increase or decrease the pressing force required for the battery block. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-8 In this embodiment of the invention, an assembly device for a watch battery and its casing includes an assembly platform 1. The upper end of the assembly platform 1 is provided with a placement mechanism, which includes a storage rack 203 and a movable placement plate 201. A watch casing 303 is placed on the upper end of the placement plate 201, and the placement plate 201 is configured as a "U" shape. An installation mechanism for placing materials from the storage rack 203 onto the placement plate 201 is installed inside the assembly platform 1. The installation mechanism includes an installation tube 310 and a lifting tube 311 that can move up and down inside the installation tube 310. The lifting tube 311 moves up and down on the inner wall of the installation tube 310, thereby keeping the pressure during battery installation within a suitable range. A limiting mechanism is provided between the lifting tube 311 and the installation tube 310. The limiting mechanism includes several push rings 402 coaxially arranged inside the lifting tube 311. Each push ring 402 has a push rod 403 fixedly installed on its outer wall. Multiple push sleeves 404 corresponding to push rods 403 are fixedly installed on the inner wall of the lifting tube 311, and the push rods 403 are slidably disposed inside the push sleeves 404 and will not slide out; A limiting spring 406 is fixedly installed on the inner wall of the mounting tube 310 and the corresponding push sleeve 404. A stop block 405 is fixed to the other end of the limiting spring 406. Under normal conditions, the stop block 405 is located inside the push sleeve 404. During the movement of the push rod 403, it can push the stop block 405 out of the push sleeve 404. At this time, the lifting tube 311 can move freely upward. The inner wall of the mounting tube 310 has a mounting groove corresponding to the stop block 405. The stop block 405 is slidably installed in the mounting groove. The push sleeve 404 penetrates the inner wall of the lifting tube 311. When the push sleeve 404 moves to the position corresponding to the stop block 405, the limiting spring 406 pushes the stop block 405 into the push sleeve 404, thereby fixing and blocking the lifting tube 311. When the stop block 405 moves out of the push sleeve 404, the lifting tube 311 moves. The stop block 405 plays the role of limiting the movement of the lifting tube 311.

[0026] Please see Figure 1 , Figure 2 A longitudinal slide rail 302 is fixedly installed on the upper end of the mounting platform 1, and a placement plate 201 is slidably installed on the upper end of the longitudinal slide rail 302. A storage rack 203 is fixedly installed on the upper end of the mounting platform 1, and multiple battery blocks 304 are placed inside the storage rack 203. A discharge hopper 204 is fixedly connected to the upper end of the mounting platform 1 (for details, please refer to...). Figure 2 The discharge hopper 204 is installed at the left end of the longitudinal slide rail 302. A control rod 206 is fixedly installed on the inner wall of the mounting platform 1, and a hole is provided at the end of the placement plate 201 near the control rod 206. Please refer to [link / reference]. Figure 3 Furthermore, the holes provided in the placement plate 201 correspond to the control rod 206, that is, the control rod 206 can pass through the holes through the placement plate 201. A baffle 205 is slidably connected to the upper end of the placement plate 201, and the baffle 205 and the control rod 206 are on the same vertical line. A pushing hole is provided on the side end of the baffle 205 near the control rod 206, and the size of the pushing hole matches the size of the control rod 206. When the control rod 206 is inserted into the push hole provided in the baffle 205, the control rod 206 pushes the baffle 205 to move, so that the baffle 205 no longer obstructs the watch case 303, making the discharge more convenient. The end of the placement plate 201 away from the baffle 205 is slidably installed with a pressing plate 202 that can press the watch case 303, and a spring telescopic rod is provided between the pressing plate 202 and the placement plate 201. When it is necessary to install the watch case 303, after the watch case 303 is placed on the placement plate 201, the spring telescopic rod pushes the pressing plate 202, and the pressing plate 202 and the baffle 205 press and fix the watch case 303. When the baffle 205 moves to a certain position, the spring telescopic rod pushes the watch case 303 to move.

[0027] Please see Figure 1 , Figure 3 A horizontal slide rail 301 is fixedly installed above the mounting platform 1. A pneumatic telescopic rod 305 is slidably installed at the moving end of the horizontal slide rail 301. The pneumatic telescopic rod 305 is slidably installed on the horizontal slide rail 301, making it more convenient to drive the pneumatic telescopic rod 305 to move and pick up materials. A mounting bracket 306 is fixedly installed at the output end of the pneumatic telescopic rod 305. The mounting bracket 306 is set in the shape of "U". A suction pipe 308 is fixedly installed inside the mounting bracket 306.

[0028] Please see Figure 1 , Figure 3 An air pump 307 is fixedly installed at the upper end of the air suction pipe 308, and a rotating connecting pipe 309 is rotatably installed at the lower end of the air suction pipe 308. An installation pipe 310 is rotatably installed at the lower end of the rotating connecting pipe 309, and the installation pipe 310 is fixedly connected to the mounting bracket 306. Both the air suction pipe 308 and the installation pipe 310 are fixedly installed on the mounting bracket 306, so that when the rotating connecting pipe 309 is rotated, the air suction pipe 308 and the installation pipe 310 remain stable and do not rotate.

[0029] Please see Figure 3A fixing ring 314 is fixedly installed at the lower end of the mounting tube 310, and a lifting tube 311 is slidably installed inside the mounting tube 310. A mounting cover 312 is fixedly installed at the lower end of the lifting tube 311, and a mounting ring 313 is fixedly installed at the lower end of the mounting cover 312. A telescopic spring 315 is fixedly installed between the mounting ring 313 and the fixing ring 314. When the lifting tube 311 moves up and down inside the mounting tube 310, the telescopic spring 315 between the mounting ring 313 and the fixing ring 314 causes the fixing ring 314 and the mounting ring 314 to move up and down. 313 compresses the telescopic spring 315, thereby causing the telescopic spring 315 to push the mounting ring 313 downward to press the battery block 304. The lower end of the mounting ring 313 is fixedly installed with an air suction bucket 317, and the mounting ring 313 and the air suction bucket 317 are made of rubber. The mounting ring 313 and the air suction bucket 317 are made of rubber so that when the air suction bucket 317 and the mounting ring 313 press the battery block 304, the squeezing force of the mounting ring 313 and the air suction bucket 317 on the battery block 304 is too large, which would cause damage to the battery block 304.

[0030] Please see Figure 5 , Figure 6 The pushing ring 402 is semi-circular, and several pushing rings 402 can be arranged to form a complete ring. Each pushing ring 402 corresponds to a pushing rod 403. A fixing frame 316 is fixedly installed on one end of the lifting tube 311 near the inner wall of the pushing ring 402. A limiting rod 411 is slidably installed on the other end of the fixing frame 316 near the pushing ring 402. The upper end of the limiting rod 411 is conical, and the pushing ring 402 is located above the limiting rod 411. The conical shape at the upper end of 411 makes it easier to push the push ring 402 when the limit rod 411 rises. The lower end of the limit rod 411 is fixedly installed with a push plate 401. A retaining ring 318 is fixedly installed on the outer wall of the limit rod 411. The retaining ring 318 on the limit rod 411 pushes the push ring 402 upward after the limit rod 411 moves to the appropriate position. This causes the push ring 402 to drive the lifting tube 311 upward through the push rod 403.

[0031] Please see Figure 7 , Figure 8A semi-through plate 409 is fixedly installed at the upper end of the lifting pipe 311. A threaded ring 408 is threadedly installed on the inner wall of the mounting pipe 310 near the semi-through plate 409. A sliding bracket 407 is fixedly installed on the outside of the threaded ring 408, and the sliding bracket 407 is slidably installed on the inner wall of the rotating connecting pipe 309. The threaded ring 408 is fixedly installed at both the upper and lower ends of the sliding bracket 407. Threads are provided on the inner walls of both the mounting pipe 310 and the suction pipe 308 near the threaded ring 408. When the rotating connecting pipe 309 rotates... When in motion, the sliding frame 407 begins to rotate, causing the threaded ring 408 to rotate at the threaded location on the inner wall of the mounting pipe 310 and the suction pipe 308. This causes the sliding frame 407 to slide up and down on the inner wall of the rotating connecting pipe 309. A sliding plate 410 is slidably installed on the inner wall of the sliding frame 407, and the gap in the sliding plate 410 matches the gap in the semi-through plate 409. After the sliding plate 410 on the sliding frame 407 and the semi-through plate 409 at the upper end of the lifting pipe 311 are in contact, a complete sealing ring is formed.

[0032] The working principle of this invention is as follows: After the watch case 303 is placed and fixed on the placement plate 201, the horizontal slide rail 301 and the suction pump 307 are activated to move the suction bucket 317 to one side of the storage rack 203. Then, the pneumatic telescopic rod 305 is activated to push the mounting bracket 306 downward, causing the suction bucket 317 to pick up the battery block 304 placed on the storage rack 203. The horizontal slide rail 301 is activated again to move the battery block 304 picked up by the suction bucket 317 to the position where the watch case 303 needs to be installed and fixed. Then, the pneumatic telescopic rod 305 is activated to push the suction bucket 317 downward. 7. Push the battery block 304 to the position where the watch case 303 needs to be placed. When the pneumatic telescopic rod 305 continues to descend and press the battery block 304, the push plate 401 will contact the battery block 304. At this time, under the reaction force of the push plate 401, the limit rod 411 will rise and push the push ring 402 to move, so that the push rod 403 pushes the stop block 405 to move out of the push sleeve 404. At this time, the stop block 405 can no longer block the lifting tube 311. The stop ring 318 set at the upper end of the limit rod 411 pushes the push ring 402 to move upward, so that the lifting tube 311 slides upward in the inner wall of the mounting tube 310. When the lifting tube 311 retracts, the mounting ring 313 and the fixing ring 314 compress the telescopic spring 315, causing the mounting ring 313 to press the battery block 304, thereby fixing the battery block 304 in the watch case 303. As the distance between the mounting ring 313 and the fixing ring 314 gradually decreases, the pushing force provided by the telescopic spring 315 increases, and the lifting tube 311 moves a longer distance within the inner wall of the mounting tube 310. When the semi-through plate 409 installed at the upper end of the lifting tube 311 contacts the sliding plate 410 slidably installed on the sliding frame 407, the semi-through plate 409 and the sliding plate 410 seal the lifting tube 311. The negative pressure generated in the suction tube 308 drives the lifting tube 311 to move upward. After the semi-through plate 409 and the sliding plate 410 seal the lifting tube 311, the suction bucket 317 no longer sucks up the battery block 304, thus keeping the pressure of pressing the battery block 304 within a reasonable range during the installation of the battery block 304.

[0033] When using this invention, rotating the rotating connecting pipe 309 causes the threaded ring 408 at the upper end of the sliding frame 407 to rotate, causing the sliding frame 407 to move up or down. This increases or decreases the distance between the sliding frame 407 and the semi-through plate 409 installed at the upper end of the lifting pipe 311, and increases or decreases the distance between the mounting ring 313 and the fixing ring 314 compressing the telescopic spring 315. This makes it more convenient to increase or decrease the pressing force required for the battery block 304.

[0034] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
